Full textAbstract:
Anthocyanin pigmentation is an important morphological marker that is commonly used to identify rice varieties and for linkage analysis. The following study investigates the genetic factors involved in the purple stigma (Ps) and purple apiculus (Pa) traits of an important indica rice cross between Zhenshan 97 (purple stigma and purple apiculus) and Minghui 63 (grey stigma and colourless apiculus). A recombinant inbred line (RIL) population derived from this cross was used for quantitative trait loci (QTL) mapping of the purple stigma and purple apiculus traits. As a result, one major QTL for the purple stigma trait, temporarily designated qPS-1-1, and one major QTL for the purple apiculus trait, temporarily designated qPA-1-1, were mapped to the short arm of chromosome 6 in the interval between the two markers Y4073L and *P. The LOD peaks of qPS-1-1 and qPA-1-1 were 44.0127 and 173.3585, respectively. In addition, qPS-1-1 and qPA-1-1 explained 66.7416% and 98.6441% of the total phenotypic variance, respectively. The Zhenshan 97 allele increased the purple stigma trait by approximately 8.0355% (for qPS-1-1) and 9.8863% (for qPA-1-1). Moreover, since qPS-1-1 and qPA-1-1 were strongly correlated, they were also located in the same vicinity of the C gene on the short arm of chromosome 6, which suggested that the two QTL might be the same. By comparing these and previous results, it was deduced that qPS-1-1 or qPA-1-1 was the C gene and was pleiotropic for both the colouration of the apiculus and the colouration of the stigma in rice.

Full textAbstract:
In this work, we first propose a parallel batch switching algorithm called Small-Batch Queue-Proportional Sampling (SB-QPS). Compared to other batch switching algorithms, SB-QPS significantly reduces the batch size without sacrificing the throughput performance and hence has much lower delay when traffic load is light to moderate. It also achieves the lowest possible time complexity of O(1) per matching computation per port, via parallelization. We then propose another algorithm called Sliding-Window QPS (SW-QPS). SW-QPS retains and enhances all benefits of SB-QPS, and reduces the batching delay to zero via a novel switching framework called sliding-window switching. In addition, SW-QPS computes matchings of much higher qualities, as measured by the resulting throughput and delay performances, than QPS-1, the state-of-the-art regular switching algorithm that builds upon the same underlying bipartite matching algorithm.

Vibration signal parameter estimation for rotating machinery diagnostics operating under variable speedconditions is considered. At first, we provide a brief survey of existing methods for Quadratic Phase Signal (QPS)parameter estimation. Then, we introduce improved solutions for the general QPS case and the Order QPS (O-QPS)case, respectively. For all considered cases (namely the QPS, O-QPS with tachometer and O-QPS without tachometer),we develop the Cramer Rao Bounds to assess and compare the estimation performance limits for each model. Finally, wecompare the performance of all considered methods and highlight, in particular, the gain of the proposed solutions.

AbstractWe study quivers with potential (QPs) whose Jacobian algebras are finite-dimensional selfinjective. They are an analogue of the ‘good QPs’ studied by Bocklandt whose Jacobian algebras are 3-Calabi–Yau. We show that 2-representation-finite algebras are truncated Jacobian algebras of selfinjective QPs, which are factor algebras of Jacobian algebras by certain sets of arrows called cuts. We show that selfinjectivity of QPs is preserved under iterated mutation with respect to orbits of the Nakayama permutation. We give a sufficient condition for all truncated Jacobian algebras of a fixed QP to be derived equivalent. We introduce planar QPs which provide us with a rich source of selfinjective QPs.

Corpus callosum connects the bilateral primary motor cortices (M1s) and plays an important role in motor control. Using the paired-pulse transcranial magnetic stimulation (TMS) paradigm, we can measure interhemispheric inhibition (IHI) and interhemispheric facilitation (IHF) as indexes of the interhemispheric interactions in humans. We investigated how quadripulse transcranial magnetic stimulation (QPS), one form of repetitive TMS (rTMS), on M1 affects the contralateral M1 and the interhemispheric interactions. QPS is able to induce bidirectional plastic changes in M1 depending on the interstimulus intervals (ISIs) of TMS pulses: long-term potentiation (LTP)-like effect by QPS-5 protocol, and long-term depression-like effect by QPS-50, whose numbers indicate the ISI (ms). Twelve healthy subjects were enrolled. We applied QPS over the left M1 and recorded several parameters before and 30 min after QPS. QPS-5, which increased motor-evoked potentials (MEPs) induced by left M1 activation, also increased MEPs induced by right M1 activation. Meanwhile, QPS-50, which decreased MEPs elicited by left M1 activation, did not induce any significant changes in MEPs elicited by right M1 activation. None of the resting motor threshold, active motor threshold, short-interval intracortical inhibition, long-interval intracortical inhibition, intracortical facilitation, and short-interval intracortical inhibition in right M1 were affected by QPS. IHI and IHF from left to right M1 significantly increased after left M1 QPS-5. The degree of left first dorsal interosseous MEP amplitude change by QPS-5 significantly correlated with the degree of IHF change. We suppose that the LTP-like effect on the contralateral M1 may be produced by some interhemispheric interactions through the corpus callosum.

"Static anteroposterior knee laxity tests are poorly correlated to quantitative pivot shift in the ACL-deficient knee: a prospective multicentre study."

ObjectiveTo determine the relationship between preoperative static knee joint laxity and non-invasive quantitative pivot shift (QPS) in patients with anterior cruciate ligament (ACL) rupture.MethodsPatients with an ACL injury participating in a multicentre trial were analysed if they had complete preoperative data on the following laxity tests: the rolimeter, the KT-1000 (134 N and manual maximum force), the Lachman, the anterior drawer and QPS. The QPS was assessed via a non-invasive inertial sensor system and an image analysis system for tibial acceleration and lateral tibial translation, respectively. Awake examination and examination under anaesthesia (EUA) were performed. Correlation between absolute values of static laxity and the QPS for each leg was assessed by Spearman’s rho. The Lachman and the anterior drawer were dichotomised into low- and high-grade, and differences between the groups in terms of continuous values of QPS were assessed.ResultsA total of 58 patients were included (41.4% women, mean age 27.1±9.8 years). Awake static laxity and QPS acceleration were negatively correlated in the ACL-deficient knee, meaning that a greater acceleration correlated to a lesser static tibial translation, and vice versa. The mean QPS acceleration correlated with the static tests as follows: the rolimeter r=−0.30 (P=0.024), the KT-1000 134 N r=−0.25 (P=0.06) and the KT-1000 manual maximum r=−0.37 (P=0.004). A negative correlation between awake QPS acceleration and the static tests was also shown for the non-involved knee. Patients with a high-grade Lachman’s test in the EUA had significantly greater QPS acceleration (P=0.0002) and QPS translation (P<0.001) compared with patients with a low-grade. The corresponding analysis for the anterior drawer showed a significantly greater QPS translation in the high-grade group (P=0.01), while no differences were found in the QPS acceleration.ConclusionStatic anteroposterior and dynamic knee laxities, as presented by QPS, are poorly correlated in the ACL-deficient knee and should therefore be considered as separate entities of the knee examination. These findings strengthen the implementation of non-invasive technology for quantification of the pivot shift when establishing treatment algorithms for ACL reconstruction.Level of evidenceLevel III, prospective cohort.

Abstract Introduction/Objective Since the start of the new millennium, optimization of Quality and Patient Safety (QPS) has taken a renewed focus in the healthcare industry. Consequently, the Accreditation Council for Graduate Medical Education has mandated that QPS be a part of residency training. We have previously presented our curriculum designed to meet the specific needs of Pathology training programs, and covering four content areas: Handoffs, Error Management, Laboratory Administration, and Process Improvement. We are now presenting implementation. Methods To implement this curriculum, we 1) created online modules for self-directed learning on basic topics (using courses developed by IHI and CAP, and assigned articles), and paired these with faculty-facilitated interactive learning activities on more complex topics, including proficiency testing, root cause analysis and test utilization, 2) assigned every resident to a QPS project that was aligned with departmental priorities, led by a faculty advisor, and ran over 8- 10 months, and 3) appointed a QPS Chief Resident to coordinate and support the residents’ QPS activities. We measured the impact of the curriculum by comparing RISE laboratory accreditation percentiles and QPS curriculum quiz scores before and after curriculum implementation. Results After its implementation, RISE percentiles increased by at least 25 for every PGY, and QPS quiz scores increased by at least 10% for 3 of 4 PGY. Every QPS project was presented at Grand Rounds, and 4 were presented externally, including 2 at national conferences. Conclusion Our curriculum was successful in improving residents’ knowledge and competence in QPS. Challenges included designing appropriate learning activities, tracking completion of activities, coordinating faculty schedules and maintaining resident buy-in to the curriculum. We believe that the basic structure of our curriculum offers a solid foundation to which revisions can be made as QPS priorities evolve, and which can be readily adapted to other programs and locations.

25 Background: Data on the use of question prompt sheets (QPS) in palliative care is limited. Our team previously developed a single page QPS using a Delphi process. The main objective of this study was to determine the perception of helpfulness of a QPS in patient-physician communication among advanced cancer outpatients. Methods: 104 eligible patients received the QPS for use during their first palliative care clinic. Patient and physician perceptions about the QPS were assessed at the end of the visit. Patients’ anxiety was also measured pre- and post-consultation using the Spielberger State Anxiety Inventory. Results: 100/104 (96%) patients completed the study. Among those responders, most agreed that the material was helpful in communicating with their doctor (77%), clear to understand (90%), had the right amount of information (87%), and they would use a similar material in the future (76%) and recommend it to other patients(70%). Overall, 92% were satisfied with their consultation visit. Physicians perceived that the QPS was helpful to 68% of the encounters and it did not prolong the consultation in 73% of the encounters. Physician agreement on helpfulness of the QPS was not significantly different from the patients (p = 0.3). Patient anxiety improved after consultation from a mean (SD) STAI score of 39.2 (12.8) to 33.8 (10.7), p ≤ 0.0001. Conclusions: The QPS was perceived as helpful in patient-physician communication among advanced cancer outpatients and it did not increase patient anxiety. Physicians similarly reported that the QPS was helpful and it did not prolong clinic visits. Further research is needed for its widespread adoption and integration into routine clinical practice.

Full textAbstract:
Quinoa is known for its rich nutrients and bioactive compounds. In order to elucidate the preliminary structural characteristics and biological activity of polysaccharides from quinoa (QPs), five crude polysaccharides (QPE50, QPE60, QPE70, QPE80 and QPE90) were successively fractionated by gradient ethanol, and their physicochemical properties, antioxidant and antidiabetic activities were analyzed. The results implied that their total sugar contents were 52.82%, 63.69%, 67.15%, 44.56%, and 41.01%, and their weight-average molecular weights were 13,785 Da, 6489 Da, 4732 Da, 3318 Da, and 1960 Da, respectively. Glucose was a predominantly monosaccharide in these QPs, which together in QPE50, QPE60, QPE70, QPE80, and QPE90, respectively, made up 94.37%, 87.92%, 92.21%, 100%, and 100% of the total polysaccharide. Congo red test showed that all five QPs contained triple-helix structure. The Fourier transform-infrared spectroscopy (FT-IR) and X-ray diffractometry (XRD) results suggest that the QPs form a semi-crystalline polymer constituted typical functional groups of polysaccharide including CO, CH and OH. The thermogravimetric analysis (TGA) of QPs showed that weight loss was at about 200 °C and 320 °C. The observation from scanning electron microscope (SEM) and atomic force microscope (AFM) image indicated that the morphology of QPs exhibited spherical shape. Antioxidant and antidiabetic assay exhibited that all five QPs samples had certain antioxidant and antidiabetic activities, and QPE90 showed the best antioxidant and antidiabetic activity. Overall, QPs present a promising natural source of food antioxidants and antidiabetic agents.

ObjectiveThe objective of the current study was to evaluate the utility and ease of use of a novel non-invasive tablet-based application for quantification of the pivot shift (QPS) in a multicentre setting.MethodsNine senior orthopaedic surgeons were recruited from academic medical centres and enrolled a total of 90 subjects. All surgeons received video and electronic training on how to perform QPS measurement using a novel tablet-based visual tracking system. Skin markers were used for visual tracking. Each orthopaedic surgeon performed a pivot shift test and obtained a QPS measurement for 10 subjects with known anterior cruciate ligament (ACL) injuries. Anterior translation of the lateral tibial compartment during the reduction event (in millimetre) was recorded. After all subjects were evaluated, the surgeons completed a survey about the ease of use, utility and willingness to use the mobile-based application in clinical practice. All automated visual tracking used to calculate anterior translation of the lateral tibial compartment was manually evaluated to ensure accurate tracking of skin markers. Statistical comparison was made between groups using Student’s t-test with significance defined as p<0.05.ResultsThe results showed that there is adequate tracking of skin markers to provide a QPS measurement across multiple academic medical centres and surgeons in only 70% of subjects. In 27 of 90 subjects, there were tracking errors which resulted in an invalid QPS measurement. Tracking errors were due to background noise, including objects in the room which were the same colour as the skin markers or use of skin preparation solution similar in colour to the skin markers. The QPS measurement was 3.2±1.8 mm, 2.4±1.3 mm in isolated ACL deficiency, and 3.2±2.0 mm with combined ACL and meniscus injury (not significant). There was significant variation among the QPS measurements of different surgeons (p=0.008).ConclusionThis study showed that mobile-based QPS measurement software can be used intraoperatively to allow surgeons greater objective feedback regarding the rotatory laxity of the knee prior to and following ACL reconstruction. Software upgrades with improved real-time feedback could help prevent errors in measurement and improve utility of QPS for assessment of injury severity in subjects.Level of evidenceLevel III.

ABSTRACT Microorganisms are intentionally added at different stages of the food and feed chain (food or feed additive, novel food or plant protection product) and are subjected to regulation and safety assessment by the European Food Safety Authority. Safety evaluation is based on application dossiers for market authorisation to the European Commission. The qualified presumption of safety (QPS) concept was developed in 20032 to provide a harmonised generic safety pre-appraisal of the above microorganisms. Unambiguously defined biological taxonomic units (TUs) are assessed for their body of knowledge, their safety and their end use. Identified safety concerns for a certain TU can be, where reasonable in number and not universally present, reflected as ‘qualifications.’ Strains belonging to TUs having QPS status may benefit of a fast track evaluation. The lowest TU for which the QPS status is granted is the species level for bacteria and yeasts and the family for viruses. The QPS concept is also applicable to genetically modified microorganisms used for production purposes. Based on the current body of knowledge and/or the ambiguous taxonomic position, some TUs, such as filamentous fungi, bacteriophages, Enterococcus faecium, Escherichia coli, Streptomyces spp. and Oomycetes, are not considered liable for QPS status.

An AI tool called the Quantitative Problem Solver (QPS) has been developed for building knowledge based systems which can solve quantitative problems in science and engineering. QPS can store and manipulate quantitative knowledge comprising numerical data and scientific laws represented by formulas. The human interface is based on the symbols commonly used by scientists and engineers. All knowledge is represented as objects and classes in an object-oriented knowledge base. QPS employs the familiar Problem Decomposition strategy for selecting the correct sequence of equations needed for solving problems and it has been tested by the building of knowledge based systems to solve several simple problems in Engineering and Physics.

ObjectivesTo investigate, prior to an oncology consultation, the use of a pre-prepared list of evidence based questions, Question Prompt Sheet (QPS), compared with a Question List (QL), a patient self-generated list of questions.DesignMulti-centred, randomised controlled trial.SettingSecondary-care patients attending three outpatient oncology clinics in Northern Italy.Participants308 women completed the study. Inclusion criteria were an age between 18 and 75 years, a recent diagnosis of early stage, non-metastatic breast cancer, adequate Italian language skills, no previous oncology visits and no evidence of cognitive impairment.InterventionPatients received the QPS or the QL prior to the consultation, completed it without suggestion or coaching session and delivered back before the visit.The consultations were audio-recorded and analysed for the number and content of questions. Multilevel linear models were used to compare the two groups.Outcome measuresThe primary outcome was the comparison of questions asked between QPS and QL group. Secondary outcomes included satisfaction about questions asked, satisfaction with decision, and level of anxiety.ResultsPatients in the QPS and QL group asked 13 and 16 questions respectively. The difference was not significant (b=1.7, CI –0.3 to 3.6, p=0.10). A mean of 22 questions was selected in the QPS, while a mean of 2 questions was written in the QL. Patients in the QPS group were significantly less satisfied (t=3.60, p<0.01) with questions asked but wanted less additional information (t=2.20, p<0.05). Levels of patient decisional satisfaction were equivalent between groups. Similarly, anxiety levels were equal between groups prior to the consultation and decreased in similar way after the consultation.ConclusionsBoth interventions have similar impact on patients’ participation in terms of question asking during the consultation. Future research is needed in order to explore which components of the interventions are really useful and efficacious.Trial registrationClinicalTrials.govNCT01510964

Full textAbstract:
AbstractThe costs of occupational stress are rising and employers increasingly need to address occupational stress, prevention and rehabilitation issues. However, there is a relative lack of understanding about implementing strategies within specific organisational contexts. Extant literature indicates a need for integrated prevention and rehabilitation strategies that address specific organisational climates that contribute to stress. The Queensland Police Service (QPS) is one policing organisation facing significant occupational stress issues requiring organisational solutions. This article describes a Participatory Action Research case study, the aim of which is to develop an occupational rehabilitation system within the QPS to address identified stress issues. A combination of background information, interview and focus group data is being used to determine stress issues and provide potential solutions to specifically address the needs of the QPS. The findings of this study emphasise the importance of participant involvement in identifying issues and generating solutions, as well as demonstrating the value of taking a systemic approach. The findings suggest that the use of the Participatory Action Research approach is invaluable in promoting the long-term success of the QPS change process.

Full textAbstract:
Abstract Quantifier phrases (QP) can co-occur in a single sentence, which may cause ambiguity in terms of scope relation, viz. wide scope and narrow scope interpretations. Aoun & Li (1993) claim that quantifier scope ambiguity also exists in Chinese passive construction, such as yige nűren bei meige ren ma ‘a woman was scolded by everyone’. Following Lee (1986)’s proposal, it is argued in this paper that the scopal relations of Chinese QPs are not purely syntactic as in Aoun & Li’s analysis, but should be determined by the interaction between syntax, semantics, and pragmatics. Based on naturalistic data, it is shown that (i) Chinese QPs can be classified into whQP, distributive-universal QP and group-denoting QP, whose semantic properties determine the scope relations between them; (ii) in general, a QP is devoid of referentiality, yet it can acquire referentiality depending on its co-occurrence with other QPs or contextual factors; (iii) the subject definiteness constraint in Chinese, a language-specific constraint, would affect the interpretation of subject QPs in Chinese passive construction.

Full textAbstract:
Queue Proportional Scheduling (QPS) has been shown to be throughput optimal for Gaussian Broadcast Channels. This paper examines the use of QPS for Video Broadcasting. First, the behavior of QPS is examined as the scheduling frequency is reduced and a method is proposed that uses statistics on the arrival rates to improve its performance. The reduction of the scheduling frequency simplifies the scheduler and decreases the required operations. Then, the packet delay variation is modeled using a Markov Chain approach leading to a method for approximating the packet delay distribution. Based on the resulting distribution, it is discussed how the video encoding rate can be chosen in order to reduce the expected distortion of streams transmitted through Broadcast Channels.

Full textAbstract:
In this paper, the sea surface wind speed (SSWS) retrieval from Gaofen-3 (GF-3) quad-polarization stripmap (QPS) data in vertical-vertical (VV), horizontal-horizontal (HH), and vertical-horizontal (VH) polarizations is investigated in detail based on 3170 scenes acquired from October 2016 to May 2018. The radiometric calibration factor of the VV polarization data is examined first. This calibration factor generally meets the requirement of SSWS retrieval accuracy with an absolute bias of less than 0.5 m/s but shows highly dispersed characteristics. These results lead to SSWS retrievals with a small bias of 0.18 m/s, but a rather high root mean square error (RMSE) of 2.36 m/s when compared with the ERA-Interim reanalysis model data. Two refitted polarization ratio (PR) models for the QPS HH polarization data are presented. Based on a combination of the incidence angle-dependent and azimuth angle-dependent PR model and CMOD5.N, the SSWS derived from the QPS HH data shows a bias of 0.07 m/s and an RMSE of 2.26 m/s relative to the ERA-Interim reanalysis model wind speed. A linear function relating SSWS and the normalized radar cross section (NRCS) of QPS VH data is derived. The SSWS data retrieved from the QPS VH data show good agreement with the WindSat SSWS data, with a bias of 0.1 m/s and an RMSE of 2.02 m/s. We also apply the linear function to the GF-3 Wide ScanSAR data acquired for the typhoon SOULIK, which yields very good agreement with the model results. A comparison of SSWS retrievals among three different polarization datasets is also presented. The current study and our previous work demonstrate that the general accuracy of the SSWS retrieval based on GF-3 QPS data has an absolute bias of less than 0.3 m/s and an RMSE of 2.0 ± 0.2 m/s relative to various datasets. Further improvement will depend on dedicated radiometric calibration efforts.

Full textAbstract:
A compression method for good visual quality is proposed in this paper. It is based on JPEG-XR. The visual quality is measured by structural similarity (SSIM). By some image compression experiments, the minimum SSIM is determined in a manual way. It represents the required visual quality. The image activity measure (IAM) is selected as an image feature. The relationship between IAM and image compression performance under different quantization parameters (QPs) is analyzed. Based on this relationship, proper QPs can be chosen for different images. Then JPEG XR can be used to compress images with these QPs, which will result in good visual quality with fewer bits consumed. The experiments have verified the effectiveness of the proposed method.

Full textAbstract:
25 Background: An effective communication strategy is the fundamental backbone in the delivery of an impeccable palliative care intervention. Different communication tools are sometimes utilized to enhance discussions between patients and their physicians. An example is a question prompt sheet (QPS) which is a structured list of potential questions available for the patient to ask their doctor during a clinical encounter. Although it has been shown to improve physician-patient interaction during clinical consultations, there is paucity of data on its use in the palliative care setting. The objective of this study was to develop a QPS that is feasible and applicable in palliative care clinical practice. Methods: An expert group of experienced physicians and mid-level providers were invited to participate in the study. The process was conducted in 3 Delphi rounds. In the last round, the top 25 questions with the highest level of endorsement were chosen and used towards the development of the QPS. Results: One hundred percent of the 22 experts invited to participate in the study accepted the invitation and completed all the 3 Delphi rounds. They consisted of 82% physicians and 18% mid-level providers. Participants were mostly males (59%), had a median age of 42 years, and a median of 8 years’ experience in palliative care. 98% of the top 25 questions for the QPS were endorsed by at least 50% of the expert panel in round 3. Twenty-eight percent of the questions were about symptoms, treatment and lifestyle, 24% were about commonly asked questions by caregivers, 20% were regarding end-of-life issues, 16% were regarding the nature of palliative care service, and 12% were regarding the type of available support. The question which had the highest number of endorsements among the panel members was “Is there someone I can talk to about my fears, concerns, spiritual or religious needs?” Conclusions: A 25-item, single page QPS containing some of the most relevant questions in diverse aspects of advanced cancer care and feasible for use in clinical practice was developed in this study. Further studies are needed to determine the clinical effectiveness of the QPS in assisting patient physician communication.

Full textAbstract:
A major issue for the implementation of large-scale superconducting quantum circuits is the interaction with interfacial two-level system (TLS) defects that lead to qubit parameter fluctuations and relaxation. Another major challenge comes from nonequilibrium quasiparticles (QPs) that result in qubit relaxation and dephasing. Here, we reveal a previously unexplored decoherence mechanism in the form of a new type of TLS originating from trapped QPs, which can induce qubit relaxation. Using spectral, temporal, thermal, and magnetic field mapping of TLS-induced fluctuations in frequency tunable resonators, we identify a highly coherent subset of the general TLS population with a low reconfiguration temperature ∼300 mK and a nonuniform density of states. These properties can be understood if the TLS are formed by QPs trapped in shallow subgap states formed by spatial fluctutations of the superconducting order parameter. This implies that even very rare QP bursts will affect coherence over exponentially long time scales.

Full textAbstract:
This paper proposes an innovative multi-thread stochastic optimization approach for the calibration of microscopic traffic simulation models. Combining Quasi-Monte Carlo (QMC) sampling and the Particle Swarm Optimization (PSO) algorithm, the proposed approach, namely the Quasi-Monte Carlo Particle Swarm (QPS) calibration method, is designed to boost the searching process without prejudice to the calibration accuracy. Given the search space constructed by the combinations of simulation parameters, the QMC sampling technique filters the searching space, followed by the multi-thread optimization through the PSO algorithm. A systematic framework for the implementation of the QPS QMC-initialized PSO method is developed and applied for a case study dealing with a large-scale simulation model covering a 6-mile stretch of Interstate Highway 66 (I-66) in Fairfax, Virginia. The case study results prove that the proposed QPS method outperforms other methods utilizing Genetic Algorithm and Latin Hypercube Sampling in achieving faster convergence to obtain an optimal calibration parameter set.

"Augmentation of Anatomic Anterior Cruciate Ligament Reconstruction With Lateral Extra-articular Tenodesis Does Not Significantly Affect Rotatory Knee Laxity: A Time Zero, In Vivo Kinematic Analysis." American Journal of Sports Medicine 48, no. 14 (November 11, 2020): 3495–502. http://dx.doi.org/10.1177/0363546520966624.
Full textAbstract:
Background: The pivot-shift test is used to assess for rotatory knee laxity in the anterior cruciate ligament (ACL)-deficient knee and ACL-reconstructed knee; however, the pivot shift uses a subjective grading system that is limited by variability between examiners. Consequently, quantified pivot shift (QPS) test software (PIVOT iPad application) has been developed and validated to measure the magnitude of rotatory knee laxity during the positive pivot-shift test. Purpose: To employ intraoperative QPS (iQPS) to assess for differences in residual rotatory knee laxity after ACL reconstruction (ACLR) versus ACLR augmented with lateral extra-articular tenodesis (ACLR + LET), and to employ iQPS to determine if ACLR and/or ACLR + LET result in overconstrained knee kinematics when compared with the contralateral knee. Study Design: Cohort study; Level of evidence, 2. Methods: iQPS was performed in 20 patients by a single surgeon on both the operative and contralateral knees before ACLR. ACLR was augmented with a LET if the lateral compartment tibial translation measured during QPS was greater than or equal to double the amount of lateral tibial compartment translation measured for the contralateral knee. After each reconstruction (ACLR or ACLR + LET), iQPS measurements were performed. iQPS data were compared with the preoperative QPS measurements of the operative and contralateral knees. Postoperative iQPS data were compared with both the preoperative QPS measurements of the operative and contralateral knees with paired samples t tests. Categorical variables were compared using the Fisher exact test. Results: The mean age in the cohort was 17.3 years (range, 15-24 years). There were no significant differences between the groups in terms of the proportion of male patients (ACLR: 5 male, 5 female vs ACLR + LET: 4 male, 6 female) or age (ACLR: 17.7 ± 3.3 years; 95% CI, 15.4-24.0 vs ACLR + LET: 16.8 ± 2.8 years, 95% CI, 14.8-22.0; P = .999). There were no significant differences between the groups with respect to preoperative QPS performed during examination under anesthesia (ACLR: 4.7 ± 2.0 mm; 95% CI, 3.3-6.1 vs ACLR + LET: 3.6 ± 1.8 mm; 95% CI, 2.3-4.9; P = .2). Both ACLR and ACLR + LET resulted in significant decreases in rotatory knee laxity when compared with preoperative QPS measurements (ACLR: –3.4 ± 1.7 mm; 95% CI, −4.6 to −2.2; P < .001: ACLR + LET: –2.6 ± 1.9 mm; 95% CI, −3.9 to −1.3; P < .002). Moreover, when compared with isolated ACLR, ACLR + LET did not result in a significantly smaller magnitude of change in iQPS between the pre- and postoperative states ( P = .3). Conclusion: Both ACLR and ACLR + LET resulted in significant decreases in rotatory knee laxity. The augmentation of ACLR with LET did not change the constraint of the knee with respect to lateral compartment translation as measured during iQPS.

With further research, the theory of local discrimination of orthogonal product states (OPSs) becomes more and more perfect. In this paper, we present a quantum proxy signature (QPS) scheme based on a set of OPSs that cannot be exactly discriminated by local operations and classical communation (LOCC). Our scheme possesses all the properties of QPS. More importantly, no one can obtain any meaningful information of a signature owing to the different particles of an OPS are separately transmitted. We show that our scheme is secure by a detailed security analysis.

We discuss some basic concepts and present a numerical procedure for finding the minimum-norm solution of convex quadratic programs (QPs) subject to linear equality and inequality constraints. Our approach is based on a theorem of alternatives and on a convenient characterization of the solution set of convex QPs. We show that this problem can be reduced to a simple constrained minimization problem with a once-differentiable convex objective function. We use finite termination of an appropriate Newton’s method to solve this problem. Numerical results show that the proposed method is efficient.

"Lateral Extra-Articular Tenodesis Does Not Affect Rotatory Knee Instability in Anatomic ACL Reconstruction." Orthopaedic Journal of Sports Medicine 7, no. 7_suppl5 (July 2019): 2325967119S0029. http://dx.doi.org/10.1177/2325967119s00295.
Full textAbstract:
Objectives: Single-bundle, anatomic anterior cruciate ligament reconstruction (ACLR) may not fully restore rotatory knee stability, and the addition of a lateral extra-articular tenodesis (LET) has been proposed as means for reducing residual rotatory knee instability. However, the magnitude of the in vivo, time zero effects of these procedures on rotatory knee instability remain poorly defined. The pivot shift test is used to assess for rotatory knee instability; however, it is a subjective grading system with limited generalizability and ability to predict clinical outcomes. Consequently, a quantified pivot shift (QPS) test software application, PIVOT iPad, has been developed and validated to measure the magnitude of rotatory knee laxity. The objective of this study was use intraoperative QPS (iQPS) to assess for differences in residual rotatory knee instability after ACLR versus ACLR augmented with lateral extra-articular tenodesis (ACLR + LET.) Methods: During examination under anesthesia (EUA), QPS was performed on both the operative and non-operative knees prior to ACLR (Figure 1A) Three, yellow ¾ inch markers were attached to skin overlying bony landmarks: lateral epicondyle, Gerdy’s tubercle and 3 cm posterior to Gerdy’s tubercle. The PIVOT software application was used to measure lateral compartment translation (Figure 1B) ACLR were randomly augmented with a LET if the lateral compartment translation measured during QPS was greater than or equal to double the amount of lateral compartment translation measured for the unaffected knee. iQPS measurements were subsequently performed after either ACLR or ACLR + LET with sterile markers (Figure 1C) iQPS data were recorded and compared to both the preoperative QPS measurements of the affected and unaffected knees. Based upon normative QPS data established from a database of >150 previously performed ACLR at our institution, it was determined that 8 patients in each group would be required to achieve 80% power with an effect size of 1.2 mm and an alpha level of 0.05. Post-procedure iQPS data were compared to preoperative QPS measurements with paired samples t-tests. Results: iQPS measurements were performed in 20 ACLR (10 ACLR and 10 ACLR + LET). The mean age in the cohort was 17.3 years old (range: 17-24 years old.). Both ACLR and ACLR + LET resulted in significant decreases in rotatory knee instability when compared to preoperative QPS measurements (pre-ACLR: 4.7 ± 1.9 v. post-ACLR: 1.3 ± 0.70, P < 0.001; pre-ACLR +LET: 3.6 ± 1.8 v. post-ACLR + LET: 0.9 ± 0.5, P < 0.001.) When comparing isolated ACLR to ACLR + LET, no significant differences were observed in the magnitude of change in iQPS between the pre and post-intervention states (ACLR: - 3.5 ± 1.6 mm v. ACLR + LET: -1.5 ± 3.1 mm, P = N.S.) Furthermore, there were no significant differences in lateral compartment translation between the operative knees and non-operative knees (ACLR: -0.1 ± 0.9 mm v. ACLR + LET: -0.5 ± 1.0 mm, P = N.S.), suggesting that neither ACLR nor ACLR + LET led to over-constrained kinematics. Conclusion: In this randomized control study, both ACLR and ACLR + LET resulted in significant decreases in rotatory knee instability. However, there were no significant differences in time-zero, rotatory knee instability detected between isolated ACLR versus ACLR combined with LET in patients. The utility of combining a LET with ACLR remains unclear, and future research is necessary to refine the indications for LET in patients with high-grade rotatory knee instability.

Full textAbstract:
Polymer-supported quaternary phosphonium salt (PS-QPS) was explored as effective catalyst for the coupling reaction of carbon dioxide with epoxides. The results indicated that cyclic carbonates with high yields (98.6%) and excellent selectivity (100%) could be prepared at the conditions of 5 MPa CO2, 150°C, and 6 h without the addition of organic solvents or cocatalysts. The effects of various reaction conditions on the catalytic performance were investigated in detail. The catalyst is applicable to a variety of epoxides, producing the corresponding cyclic carbonates in good yields. Furthermore, the catalyst could be recovered easily and reused for five times without loss of catalytic activity obviously. A proposed mechanism for synthesis of cyclic carbonate in the presence of PS-QPS was discussed. The catalyst was characterized by thermogravimetric analysis (TGA), scanning electron microscopy (SEM), and Fourier transform infrared (FT-IR) spectrum. It is believed that PS-QPS is of great potential for CO2fixation applications due to its unusual advantages, such as easy preparation, high activity and selectivity, stability, low cost, and reusability.

Full textAbstract:
On 24 September 1997 the Criminal Justice Commission (CJC) released a comprehensive report entitled Integrity in the Queensland Police Service: Implementation and Impact of the Fitzgerald Inquiry Reforms, in line with its statutory obligation to report to Parliament on the implementation of the recommendations of the Inquiry. Earlier reports have examined the implementation of the Inquiry's recommendations relating to recruitment and training and the restructuring of the police service (see CJC 1993, 1994). This most recent report addresses issues such as whether the Fitzgerald reforms have enhanced the effectiveness of the complaints investigation process, led to improved standards of behaviour within the Queensland Police Service (QPS), reduced the incidence of corruption and weakened the influence of the police ‘code of silence’. In addition to providing a retrospective assessment of the ‘Fitzgerald reforms’, the report identifies key areas where further action is required by the QPS and provides a reference point against which to measure future progress. This article summarises the key findings of the report and briefly discusses the implications for further reform of the QPS and the role of the CJC in that process.

ABSTRACT In order to provide a harmonised preassessment to support risk assessment performed by the European Food Safety Authority (EFSA), the Biohazard Panel in 2007 published guidelines for evaluation of the safety of a strain included in the food chain, the Qualified Presumption of Safety (QPS). Since 2008, the Biohazard Panel has published on a regular basis an update of the microbial strains submitted for approval and extends the list of species which have been granted QPS status. The International Dairy Federation (IDF) and the European Food and Feed Cultures Association (EFFCA) have, since 2002, been conducting a project on the safety demonstration of microbial food cultures (MFCs). Following the publication of IDF Bulletin 377–2002, an inventory of MFCs was published in IDF Bulletin 455–2012 and updated most recently in IDF Bulletin 495–2018. These two lists developed by EFSA (QPS) and IDF/EFFCA both propose as an outcome an inventory of microbial species that are safe for human consumption. To avoid confusion when these two inventories are compared, this review attempts to explain the rationale that was used to develop them and explain how the two lists should be understood.

Quantum phase slips (QPS) are the primary excitations in one-dimensional superfluids and superconductors at low temperatures. They have been well characterized in most condensed-matter systems, and signatures of their existence have been recently observed in superfluids based on quantum gases too. In this review, we briefly summarize the main results obtained on the investigation of phase slips from superconductors to quantum gases. In particular, we focus our attention on recent experimental results of the dissipation in one-dimensional Bose superfluids flowing along a shallow periodic potential, which show signatures of QPS.

Full textAbstract:
Quadratic programming problems (QPs) frequently appear in control engineering. For use on embedded platforms, a QP solver implementation is required in the programming language C. A new solver for quadratic optimization problems, EmbQP, is described, which was implemented in well readable C code. The algorithm is based on the dual method of Goldfarb and Idnani and solves strictly convex QPs with a positive definite objective function matrix and linear equality and inequality constraints. The algorithm is outlined and some details for an efficient implementation in C are shown, with regard to the requirements of embedded systems. The newly implemented QP solver is demonstrated in the context of control allocation of an over-actuated vehicle as application example. Its performance is assessed in a simulation experiment.

Background: The pivot-shift test has become more consistent and reliable and is a meaningful outcome measurement after anterior cruciate ligament reconstruction (ACLR). Purpose/Hypothesis: The purpose of this investigation was to assess patient-reported outcomes (PROs) and the quantitative pivot shift (QPS) preoperatively, at time zero immediately after anatomic ACLR, and after 24 months as well as the relationship between PROs and the QPS. It was hypothesized that anatomic ACLR would restore rotatory stability measured by the pivot-shift test and that QPS measurements would be positively correlated with PROs. Study Design: Cohort study; Level of evidence, 2. Methods: The ACL-injured and contralateral uninjured knees from 89 of 107 (83.2%) enrolled patients at 4 international centers were evaluated using a standardized pivot-shift test. Tibial acceleration was assessed with an inertial sensor, and lateral compartment translation was measured using an image analysis system preoperatively, at time zero immediately postoperatively, and at follow-up after 2 years. PROs were assessed at 12 and 24 months postoperatively with the International Knee Documentation Committee (IKDC) subjective knee form, Cincinnati Knee Rating System (CKRS), Marx activity rating scale, and activity of daily living score (ADLS). Results: The mean patient age at surgery was 27 years (range, 15-45 years). A positive pivot shift preoperatively (side-to-side difference in tibial acceleration, 2.6 ± 4.0 m/s2; side-to-side difference in anterior tibial translation, 2.0 ± 2.0 mm) was reduced at time zero postoperatively (side-to-side difference in tibial acceleration, –0.5 ± 1.3 m/s2; side-to-side difference in anterior tibial translation, –0.1 ± 1.0 mm). All PROs improved from preoperatively to final follow-up at 24 months: from 56.5 to 85.5 points for the IKDC ( P = .0001), from 28.8 to 32.4 points for the CKRS ( P = .04), from 11.2 to 7.9 points for the Marx ( P < .0001), and from 75.7 to 91.6 points for the ADLS ( P < .0001). Neither preoperative nor time zero postoperative rotatory laxity assessed by the pivot-shift test correlated with PROs at 24-month follow-up. A graft retear was observed in 4 patients (4.5%) within 2 years of follow-up. Conclusion: Anatomic ACLR resulted in significantly improved and acceptable PROs at 2-year follow-up and a low failure rate. Anatomic ACLR restored QPS measurements of anterior tibial translation and tibial acceleration to those of the contralateral knee immediately after surgery while still under anesthesia, but there was no correlation between the QPS preoperatively or at time zero after ACLR and PROs at 2-year follow-up.

Full textAbstract:
In this paper, the performance of C-band synthetic aperture radar (SAR) Gaofen-3 (GF-3) quad-polarization Stripmap (QPS) data is assessed for classifying late spring and summer sea ice types. The investigation is based on 18 scenes of GF-3 QPS data acquired in the Arctic Ocean in 2017. In this study, floe ice (FI), brash ice (BI) between floes and open water (OW, ice-free area) were classified based on a mini sea ice residual convolutional network, which we call MSI-ResNet. While investigating the optimal patch size for MSI-ResNet, we found that, as the patch size continues to grow, the classification accuracy first increases and then decreases. A patch size of 31 × 31 was found to achieve the best performance. The performance of classification using different polarization combinations from the QPS data was also assessed. The vertical-vertical (VV) polarization input overestimates the FI category while incorrectly identifying most of the BI as FI. The VH polarization produces a synchronous improvement in FI, BI, and OW discrimination, with a higher overall accuracy and kappa coefficient (91.09% and 0.85, respectively) than the VV polarization (83.37% and 0.70, respectively). The combination of VV and vertical-horizontal (VH) polarizations presents a modest precision improvement for BI and OW together with a slight overestimation for FI. With VV, VH, and horizontal-horizontal (HH) polarization data as the inputs, the user’s accuracy improves to 95.12%, 93.42%, and 95.17% for FI, BI, and OW, respectively. The accuracy was assessed against visual interpretation of the sea ice classes in the images using a stratified sampling method. The application of the MSI-ResNet method to data covering the Beaufort Sea and the north of the Severnaya Zemlya archipelago was found to achieve a high overall accuracy (kappa) of 94.62% (±0.92) and 94.23% (±0.90), respectively. This is similar to the classification accuracy obtained in the Fram Strait. From the results of this study, it is shown that the MSI-ResNet method performs better than the classical support vector machine (SVM) classifier for sea ice discrimination. The GF-3 QPS mode data also show more details in discriminating scattered sea ice floes than the coincident Sentinel-1A Extra Wide (EW) swath mode data.

This paper discusses the risk analysis of single stock and portfolio returns. The stock data analyzed are BNI, BRI shares and portfolio. After obtaining a stock return, value at risk (VaR) will be estimated using the normal distribution approach, logistic distribution, and historical simulation. From the VaR results, a backtest is then conducted to test the validity of the model and the backtest results for BNI and the portfolio produce a smaller QPS on the historical simulation method compared to the normal distribution and logistics distribution approaches. This shows that BNI VaR and VaR portfolios with the historical simulation method are more consistent than other methods. While the backtest results for BRI produced the smallest QPS on the normal distribution approach compared to the logistical distribution and historical simulation approaches. This shows that the VaR BRI using the normal distribution approach is more consistent than the other methods.

In this study, 14 endophytic fungus from Quercus phillyraeoides A. Gray were isolated. Alternaria sp. QPS 05, an endophytic fungi which was isolated from the stem of Q. phillyraeoides A. Gray showed the highest α-glucosidase inhibitory activity. Further separation of ethyl acetate extract from the fungus led to the isolation of active substance from hexane-soluble fraction which give fatty acids mixture consist of palmitic acid, oleic acid, linoleic acid and linolenic acid (1) strong inhibitory activity against α-glucosidase. Isolated fatty acids (1) had inhibitory concentration (IC50) values against Saccharomyces cerevisiae was 12.10 μg/mL. The results of the present study showed that endophytic fungus from Alternaria sp. QPS 05 potentially contained a rich source of natural antidiabetic medicine.

Our purpose was to investigate the safety of the probiotic strain Lactobacillus brevis KB290. The European Qualified Presumption of Safety (QPS) evaluation approach was applied to the strain. We determined the strain's antibiotic resistance, verified it at the genetic level, and determined whether it could be transferred to intestinal microflora. Of 14 antibiotics tested, 11 showed MICs within the limits of the QPS criteria. However, the L. brevis KB290 MICs of ciprofloxacin (a fluoroquinolone), tetracycline, and vancomycin were two, four, and eight times, respectively, the breakpoint MICs suggested by the European Scientific Committee on Animal Nutrition, and the MIC of tetracycline was eight times the breakpoint MIC suggested by the European Scientific Panel on Additives and Products or Substances Used in Animal Feed. Using analysis of gapped-genome sequences, we found no known transferable determinants for tetracycline or vancomycin resistance, and we found no mutations in the quinolone resistance–determining regions of the genes encoding GyrA or ParC for ciprofloxacin resistance associated with insertion sequences, integrons, or transposons. These data were confirmed by using PCR primers specific for the respective genes. We assessed the transferability of the resistance traits in conjugation experiments with enterococci and obtained no transconjugants, strongly suggesting that the resistance traits were not transferable. This study demonstrated that the antibiotic resistance observed in L. brevis KB290 was due not to dedicated mechanisms but to intrinsic resistance. According to the QPS criteria, these results provide safety assurance for the ongoing use of L. brevis KB290 as a probiotic.

Tremor is the most common movement disorder encountered during daily neurological practice. Tremor in the upper limbs causes functional disability and social inconvenience, impairing daily life activities. The response of tremor to pharmacotherapy is variable. Therefore, a combination of drugs is often required. Surgery is considered when the response to medications is not sufficient. However, about one third of patients are refractory to current treatments. New bioengineering therapies are emerging as possible alternatives. Our study was carried out in the framework of the European project “Tremor” (ICT-2007-224051). The main purpose of this challenging project was to develop and validate a new treatment for upper limb tremor based on the combination of functional electrical stimulation (FES; which has been shown to reduce upper limb tremor) with a brain-computer interface (BCI). A BCI-driven detection of voluntary movement is used to trigger FES in a closed-loop approach. Neurological tremor is detected using a matrix of EMG electrodes and inertial sensors embedded in a wearable textile. The identification of the intentionality of movement is a critical aspect to optimize this complex system. We propose a multimodal detection of the intentionality of movement by fusing signals from EEG, EMG and kinematic sensors (gyroscopes and accelerometry). Parameters of prediction of movement are extracted in order to provide global prediction plots and trigger FES properly. In particular, quality parameters (QPs) for the EEG signals, corticomuscular coherence and event-related desynchronization/synchronization (ERD/ERS) parameters are combined in an original algorithm which takes into account the refractoriness/responsiveness of tremor. A simulation study of the relationship between the threshold of ERD/ERS of artificial EEG traces and the QPs is also provided. Very interestingly, values of QPs were much greater than those obtained for the corticomuscular module alone.

The main goal of this paper is to argue that Korean pronouns must be phi-feature-compatible with their antecedents, whereas Korean reflexives are not. It is worth pointing out that Korean pronouns are sensitive to the number feature, whereas Korean anaphors are not. A major point to note is that every-type QPs have a Q feature that is plural in its number, whereas which-type QPs have an optional Q-feature that is singular or plural in number. A further point to note is that Korean pronouns are sensitive to phi-features, which is in accordance with Safir’s (2014) hypothesis that “D-bound anaphora must be feature-compatible with its antecedent”. With respect to Korean pronouns, it is worth noting that Safir’s hypothesis does not work for Korean pronouns since they induce a bound variable reading through the phi-feature agreement. Finally, it is significant to note that Korean anaphors are not feature-compatible with antecedents and that they yield a bound variable reading regardless of their phi-features.
