Full textAbstract:
The advanced constitutive model KHSM for structured clays, which incorporates the effects of loss of structure within an elastoplastic framework, has been implemented in a finite element procedure and used to investigate the failure height and pore-water pressures of embankment A constructed at Saint Alban, Quebec. For the purpose of model comparison, simulations were also performed using the standard bubble model (KHM) without destructuration. The numerical predictions of pore-water pressures and settlements are also compared with field measurements. The results clearly demonstrate the importance of including the effects of loss of structure in the analysis.

Konsep branding pada universitas dapat memberikan reputasi yang baik untuk universitas baik dari segi pelayanan maupun fasilitas yang diberikan kepada para calon mahasiswanya. Namun, penelitian mengenai konsep branding tersebut di Indonesia masih relatif terbatas. Melalui aspek sosial, penelitian ini bertujuan untuk menyelidiki dampak nilai-nilai yang dirasakan mahasiswa Universitas Bangka Belitung (nilai utilitas, nilai hedonic dan relasional atau hubungan) terhadap Kualitas Hubungan Merek (KHM) dengan merek institusional Universitas Bangka Belitung (UBB) serta pada akhirnya pada resonansi merek (RM). Sejumlah 250 sampel yang berlokasi di Universitas Bangka Belitung dapat diambil secara online menggunakan teknik convenience sampling dan data tersebut dianaliskan melalui Persamaan Model Struktural (SEM). Hasil menunjukkan bahwa seluruh faktor prediktif dapat mempengaruhi secara positif terhadap KHM dan KHM dapat memediasi hubungan faktor-faktor prediktif dan RM. Dengan roadmap merek yang dirancang dengan baik, universitas dapat menurunkan masalah salah interpretasi oleh calon mahasiswa yang dapat menggagalkan upaya pengembangan citra merek universitas di masa depan. AbstractThe concept of branding at universities can provide a good reputation for universities both in terms of services and facilities provided to prospective students. However, research on the concept of branding in Indonesia is still relatively limited. Through social aspects, this study aims to investigate the impact of perceived values of Bangka Belitung University students (utility value, hedonic value, and relational value) on Brand Relationship Quality (BRQ) with the institutional brand of Bangka Belitung University (UBB) and finally in Brand Resonance (BR). A total of 250 samples located at Bangka Belitung University can be taken online using convenience sampling techniques and the data is analyzed through Structural Model Equations (SEM). The results show that all predictive factors can positively influence the BRQ and BRQ can mediate the relationship between predictive factors and RM. With a well-designed brand roadmap, universities can reduce the problem of misinterpretation by prospective students that can thwart efforts to develop the university's brand image in the future.

Full textAbstract:
Abstract Introduction Kigamicin (KM) is a compound isolated from Actinomycetes, which reportedly induces necrosis in pancreatic cancer cells under nutrient-starving condition but not under nutrient rich condition via PI3-kinase inhibition (Lu et al., Cancer Science 95, 547–52, 2004). Although the PI3-kinase activity is thought to be critical in the growth of myeloma cells, its actual role remains to be determined. In the present study, we evaluated KM’s anti-myeloma activity in both laboratory and primary myeloma cells and found that, contrary to the original finding in pancreatic cancer cells, KM induced necrosis in human myeloma cells both under nutrient-starving and nutrient-rich conditions. Results and discussion Myeloma cell lines (12PE and KHM-11) and primary myeloma cells purified with CD138-coated immune-magnetic beads were incubated with KM under nutrient-rich conditions. The CC50 value of KM for myeloma cells was approximately 100 nM after 24-hour exposure while pancreatic cancer cell line, PANC-1, did not show inhibition of viability even at 10 mM under nutrient-rich conditions, suggesting high sensitivity of myeloma cells to KM. When whole mononuclear cells obtained from a myeloma patient’s bone marrow were cultured with KM at a concentration of 500 nM in vitro, normal lymphocytes were spared while all myeloma cells underwent necrosis, suggesting that preferential cytotoxicity of KM in myeloma cells. Western blot analysis revealed that AKT phosphorylation decreased with KM treatment, suggesting that KM inhibits PI-3 kinase activity as previously reported. However, another pan-PI3 kinase inhibitor, LY294002, did not induce necrosis in myeloma cells, suggesting that PI3-kinase inhibition is not critically related to the cytotoxicity of KM in myeloma cells. A pan-caspase inhibitor, ZVAD-FMK, only partially inhibited cell death, suggesting that caspase is not involved in the cytotoxic function of KM, either. To further determine the mechanism of cytotoxicity in myeloma cells, a possible involvement of cyclin D1 and p21 was also examined. Western blot analysis revealed that KM completely reduced cyclin-D1 in myeloma cells. Moreover, KM induced translocation of p21 from cytoplasm to nucleus within 5 hours treatment, suggesting that KM disrupted cell cycle regulation. Finally, melphalan-resistant myeloma cell line, 11-EMS, showed significant cell death when exposed to KM even more efficiently than did melphalan-sensitive parental cell line, KHM-11. Since a number of anti-cancer reagents induce apoptosis in myeloma cells, KM induction of necrosis may represent a unique mechanism(s) and may overcome drug resistance of myeloma cells. Taking into a consideration a recent report by Lu et al. (Cancer Science 95, 547–52, 2004) showing that KM’s safe usage in a murine pancreatic cancer xenograft model, the present data suggest that KM could be a potential therapeutic agent for treatment of myeloma and warrant that further preclinial development of KM be continued.

Full textAbstract:
The heterogeneous nuclear ribonucleoproteins (hnRNPs) comprise a large family of proteins that play important roles in telomere biogenesis, DNA repair, cellular signaling, and the regulation of expression at both the transcriptional and translational levels. One of the most extensively studied hnRNP family members, hnRNP K, has been implicated in a variety of processes, including chromatin remodeling, transcription, splicing, and translation events. In this study, we analyzed processed HNRPK pseudogenes (HNRPK ψ1–ψ4) and coding sequences. HNRPK pseudogenes are apparently nonfunctional, and ψ1 might correspond to transcripts from an ancestral gene. Phylogenetic and sequence analyses suggest that HNRP genes arose by duplication, and that new structural and sequence features expanded the functions of hnRNPs. The expression analysis of hnRNP K isoforms showed that isoform a is expressed in normal testis and in non-small cell lung cancer (NCI-H1155 NSCLC cell line), although the shorter isoform (isoform b) is expressed in different tumor cell lines (IM9 B-lymphoblastoid, Hs578T human breast cancer epithelial, T98G human glioma cell lines). Using molecular modeling, we obtained KH1 and KH3 models, which pointed to important residues for DNA–protein binding and no structural differences between isoforms a and b. To our knowledge, this is the first phylogenetic study including vertebrate HNRP genes and HNRPK pseudogenes, and the first report comparing the KH1 and KH3 domains of isoforms a and b of the hnRNP K protein. New investigations in tumor samples must be done to validate the differential expression observed here. The results shown are important because the hnRNP K protein might represent a new target for pharmacologic intervention in virus replication and cancer.

Modal models are commonly encountered forms of dynamic characterization of mechanical structures. They are applied in machine-condition diagnosing as well as in monitoring processes. In research practice the most frequently applied method is Experimental Modal Analysis, and in exploitation - Operational Modal Analysis. Difficulties associated with the EMA and OMA have contributed to the increase of OMAX model applications, especially in case of energetic machines. Theoretical assumptions related with modal analysis are very strong. In reality when big and heavy structures are considered often those assumptions are not fulfilled. In the paper such situations are considered and practical solutions are showed.

To better understand and exploit the knowledge necessary to comprehend and evolve an existing system, different models can be extracted from it. Models represent the extracted information at various abstraction levels, and are useful to document, maintain, and reengineer the system. The Knowledge Discovery Metamodel (KDM) has been defined by the object management group as a meta-model supporting a large share of reverse engineering activities. Its specification has also been adopted by the ISO in 2012. This paper explores and describes alternative meta-models proposed in the literature to support reverse engineering, program comprehension, and software evolution activities. We focus on the similarity and differences of the alternative meta-models with KDM, trying to understand the potentials of reciprocal information interchange. We describe KDM and other five meta-models, plus their extensions available in the literature and their diffusion in the reverse engineering community. We also investigate the approaches using KDM and the five meta-models. In the paper, we underline the limited reuse of models for reverse engineering, and identify potential directions for future related research, to enhance the existing models and ease the exchange of information among them.

A strategy of coupling length scales from atomistic to continuum is investigated on the basis of quasicontinuum model for interface fracture problems. In the model, an atomistic region of the interest is discretized by finite elements and the positions of atoms are prescribed by means of nodal displacements of the elements with shape function for the reduction of the degrees of freedom. Total energy of the system consists of interatomic potentials, and minimized through variational method employed in conventional finite element formulation. In this study, we deal with the fracture behavior of Cu-Fe interface crack in two dimensional problems, and investigate the adequate discretization manner around the crack tip in use of quasicontinuum method.

A series of low-cycle fatigue experiments of axial-torsional loading of variable amplitudes were performed on the tubular specimens of 304 stainless steel. Two models of multiaxial low-cycle fatigue life, KBM and FS method, are evaluated based on the fatigue life data of 304 stainless steel. Rainflow cycle counting and the Liner Damage Rule are used to calculate fatigue damage. It was shown that the part prediction results are nonconservative for the two models. The life prediction is done again based on the weight function critical plane method for the two models. The prediction results are better by using the weight function critical plane method than the previous results for KBM model. But the prediction results are improved little for FS model in spite of the weight function critical plane method being used.

This study revisits the parameters of authenticity, balance, and challenge in The Kaleidoscope Career Model (KCM) concerning gender differences in midcareer. Unemployed individuals were surveyed ( n = 744) to determine gender differences in the three parameters across five segmented career stages. The results showed variance in the Authenticity, Balance and Challenge (ABC) parameters across career stages by gender, with balance increasingly important in full midcareer for women but of lesser importance for men. Authenticity showed a similar pattern for men and women, with authenticity rising for women and declining for men in very late career as predicted by the model. Challenge remained consistent for men and women, declining in importance over time. The study contribution offers sharper resonance of the KCM through closely segmented midlife career stages for an unemployed population undergoing career transitions.

Full textAbstract:
Finite element model updating is a well-known technique to better characterize the real behaviour of civil engineering structures. The updated numerical model can be used to perform a more accurate structural assessment. Herein, its effectiveness is validated through the fatigue assessment of a lively footbridge considering two different numerical models: (i) a preliminary finite element (FE) model and (ii) an updated version of the preliminary model based on the modal parameters of the footbridge identified experimentally. For this purpose, the Malecon footbridge (Murcia, Spain) has been considered. This footbridge, a cable-stayed structure, is prone to vibrate in vertical direction under continuous walking pedestrian flows so fatigue damage might be expected on its supporting cables. A detailed FE model of the footbridge has been performed and subsequently updated based on the experimental modal parameters of the structure. The behaviour of the pedestrian flows was characterized by field observations. Finally, a comparison is performed between the fatigue damage of some cables of the footbridge considering the two mentioned FE models. The safe life method was used to assess such damage. As result, a maximum relative difference around 52 % was obtained between the two numerical models.

Purpose – The purpose of this research is to examine the experiences of female CEOs in New Zealand sport using a career account approach overlaid with the Kaleidoscope Career Model (KCM). This research focuses on their successful careers, rather than constraints and barriers, which is a feature of much previous research in the area. Design/methodology/approach – Semi-structured interviews and analysis were informed by the principles of the KCM of career authenticity, balance and challenge. Seven chief executive officers in New Zealand sport organizations were interviewed. Data analysis was undertaken through a three-step coding process. Findings – Respondents highlighted the importance of authenticity, balance and challenge in different ways. The KCM model is extended by identifying sub-themes within each principle. These were, under authenticity, passion and relationship-building; under balance, self-awareness and influencing the organization; and under challenge, taking opportunities and working in sport’s gendered environment. Findings indicate that a more nuanced development of KCM is required and that decision-makers in sport organizations need to be aware of the varied drivers of women’s positive experiences. Research limitations/implications – This research contributes to an understanding of successful women’s careers, rather than focusing on barriers to success. It also extends the KCM. Future research is necessary to examine the viability of our suggested extensions to the KCM. Practical implications – While not generalizable, this study’s findings suggest that sport organization decision-makers would be well advised to understand the unique ways in which authenticity, balance and challenge are understood by their female employees. This may encourage organizations to look more closely at their cultures to ensure that they are more welcoming and supportive to women in a male-dominated industry. Originality/value – This research contributes to an understanding of successful women’s careers, rather than focusing on barriers to success. It also extends the KCM. Future research is necessary to examine the viability of our suggested extensions to the KCM.

One of the objectives of the EU research project InMAR (“Intelligent Materials for Active Noise Reduction”) is to reduce car engine noise by active control. An oilpan of a passenger car serves as a demonstrator. A concern in the application of active control is that the controlled system may change during service life (e.g. due to damage), and hence, may degrade the control performance. This paper presents two vibration-based methods that are able to autonomously detect damage and yield updated experimental models of the structure. A first approach is based on (operational) modal analysis. Based on vibration measurements, the modal parameters of the structure are estimated. The idea is now to automate this process so that, without human intervention, a representative dynamic model of the structure is always available. A second approach uses multiple-model estimation in the case when the state-space models have different state dimensions. To this end, an existing non-interacting multiple-model estimator has been extended to make it alert to jumps from one model to another. Both techniques (“Automatic Modal Analysis” and “Alert Autonomous Multiple Model Estimator”) will be applied to experimental vibration data from an oilpan of a passenger car subjected to damage (loosening of bolts).

The study of spontaneous mutations in mice over the last century has been fundamental to our understanding of normal physiology and mechanisms of disease. Here we studied the phenotype and genotype of a novel mouse model we have called the New Zealand Ginger (NZG/Kgm) mouse. NZG/Kgm mice are very large, rapidly growing, ginger-colored mice with pink eyes. Breeding NZG/Kgm mice with CAST/Ei or C57BL/6J mice showed that the ginger coat colour is a recessive trait, while the excessive body weight and large body size exhibit a semidominant pattern of inheritance. Backcrossing F1 (NZG/Kgm × CAST/Ei) to NZG/Kgm mice to produce the N2 generation determined that the NZG/Kgm mouse has two recessive pigmentation variant genes ( oca2 p and tyrp-1 b) and that the tyrp-1b gene locus associates with large body size. Three coat colors appeared in the N2 generation; ginger, brown, and dark. Strikingly, N2 male coat colour associated with body weight; the brown-colored mice weighed the most followed by ginger and then dark. The male brown coat-colored offspring reached adult body weights indistinguishable from NZG/Kgm males. The large NZG/Kgm mouse body size is a result of excessive lean body mass since these mice are not obese or diabetic. NZG/Kgm mice exhibit an unusual pattern of fat distribution; compared with other mouse strains they have disproportionately higher amounts of subcutaneous and gonadal fat. These mice are susceptible to high-fat diet-induced obesity but are resistant to high-fat diet-induced diabetes. We propose NZG/Kgm mice as a novel model to delineate gene(s) that regulate 1) growth and metabolism, 2) resistance to Type 2 diabetes, and 3) preferential fat deposition in the subcutaneous and gonadal areas.

Full textAbstract:
Abstract In PKC 2000, Pointcheval presented a generic technique to make a highly secure cryptosystem from any partially trapdoor one-way function in the random oracle model. More precisely, any suitable problem providing a one-way cryptosystem can be efficiently derived into a chosen-ciphertext attack (CCA) secure public key encryption (PKE) scheme. In fact, the overhead only consists of two hashing and a XOR. In this paper, we consider the key-dependent message (KDM) security of the Pointcheval’s transformation. Unfortunately, we do not know how to directly prove its KDM-CCA security because there are some details in the proof that we can not bypass. However, a slight modification of the original transformation (we call twisted Pointcheval’s scheme) makes it possible to obtain the KDM-CCA security. As a result, we prove that the twisted Pointcheval’s scheme achieves the KDM-CCA security without introducing any new assumption. That is, we can construct a KDM-CCA secure PKE scheme from partial trapdoor one-way injective family in the random oracle model.

Full textAbstract:
Context: Prospective measures of high external knee-abduction moment (KAM) during landing identify female athletes at increased risk of patellofemoral pain (PFP). A clinically applicable screening protocol is needed. Objective: To identify biomechanical laboratory measures that would accurately quantify KAM loads during landing that predict increased risk of PFP in female athletes and clinical correlates to laboratory-based measures of increased KAM status for use in a clinical PFP injury-risk prediction algorithm. We hypothesized that we could identify clinical correlates that combine to accurately determine increased KAM associated with an increased risk of developing PFP. Design: Descriptive laboratory study. Setting: Biomechanical laboratory. Patients or Other Participants: Adolescent female basketball and soccer players (n = 698) from a single-county public school district. Main Outcome Measure(s): We conducted tests of anthropometrics, maturation, laxity, flexibility, strength, and landing biomechanics before each competitive season. Pearson correlation and linear and logistic regression modeling were used to examine high KAM (>15.4 Nm) compared with normal KAM as a surrogate for PFP injury risk. Results: The multivariable logistic regression model that used the variables peak knee-abduction angle, center-of-mass height, and hip rotational moment excursion predicted KAM associated with PFP risk (>15.4 NM of KAM) with 92% sensitivity and 74% specificity and a C statistic of 0.93. The multivariate linear regression model that included the same predictors accounted for 70% of the variance in KAM. We identified clinical correlates to laboratory measures that combined to predict high KAM with 92% sensitivity and 47% specificity. The clinical prediction algorithm, including knee-valgus motion (odds ratio [OR] = 1.46, 95% confidence interval [CI] = 1.31, 1.63), center-of-mass height (OR = 1.21, 95% CI = 1.15, 1.26), and hamstrings strength/body fat percentage (OR = 1.80, 95% CI = 1.02, 3.16) predicted high KAM with a C statistic of 0.80. Conclusions: Clinical correlates to laboratory-measured biomechanics associated with an increased risk of PFP yielded a highly sensitive model to predict increased KAM status. This screening algorithm consisting of a standard camcorder, physician scale for mass, and handheld dynamometer may be used to identify athletes at increased risk of PFP.

The unique architecture of neurons requires the establishment and maintenance of polarity, which relies in part on microtubule-based transport to deliver essential cargo into dendrites. To test different models of differential motor protein regulation and to understand how different compartments in neurons are supplied with necessary functional proteins, we studied mechanisms of dendritic transport, using Drosophila as a model system. Our data suggest that dendritic targeting systems in Drosophila and mammals are evolutionarily conserved, since mammalian cargoes are moved into appropriate domains in Drosophila. In a genetic screen for mutants that mislocalize the dendritic marker human transferrin receptor (hTfR), we found that kinesin heavy chain (KHC) may function as a dendritic motor. Our analysis of dendritic and axonal phenotypes of KHC loss-of-function clones revealed a role for KHC in maintaining polarity of neurons, as well as ensuring proper axonal outgrowth. In addition we identified adenomatous polyposis coli 1 (APC1) as an interaction partner of KHC in controlling directed transport and modulating kinesin function in neurons.

It is known that chaotic oscillations for chemical reactions can be described by non-stationary kinetic models consisting of three ordinary differential equations. Rossler established the first examples of chemical reactions, including the two-route five-stage reaction of the Villamovski-Rossler, with three intermediate substances, containing three autocatalytic on intermediates stages, the dynamic model of which describes chaotic oscillations. In given article presents a simple one-route four-stages reaction A+E=D involving two autocatalytic and one linear on intermediate stage, the non-stationary kinetic model of which describes chaotic oscillations. The non-stationary kinetic model under the assumption of quasistationarity with respect to the main substances within the framework of the law of acting masses is a system of three ordinary differential equations. The presence of chaos is confirmed by numerical calculations of the kinetic model and Lyapunov exponentials. The Lyapunov exponents satisfy the condition L1+L2+L3<0, which proves the existence of chaotic oscillations.Forcitation:Kol'tsov N.I. Chaotic oscillations in simplest chemical reaction. Izv. Vyssh.

In the model updating process, the objective function is usually set as the weighted sum of the difference between analytical and experimental dynamic characteristics. But it is difficult to select the weighting factors since the relative importance of each parameter to updated results is not obvious but specific for different problem. To overcome this problem, multi-objective genetic algorithm (GA) is introduced into model updating by Gyeong-Ho Kim since there is no need for selecting weighting values in multi-objective optimization technique. To complex structures, however, it is difficult to update the structural models by GA because of the relative low efficiency. While Taguchi updating method, deemed as an efficient and robust method, is a good choice to update the models of large structures. But Taguchi method is only applied to solve the single objective optimization problem of model updating. Therefore, this paper proposed improved Taguchi updating method to deal with the problem of model updating using multi-objective optimization technique. Then the proposed method is applied to update the model of a 14-bay beam with measured frequencies and modal shapes. The updated results show that the proposed method is promising to structural model updating.

The erosion of the river bed material at bridge pier foundation produced by scour events is one of the main causes of the observed masonry bridges failures and collapses. Foundation settlements and rotations derived from the reduction of the footprint under the piers threaten masonry arch bridges integrity more than any gravity load. The resulting effect on the structure is the development of cracking mechanisms on the arches which may affect the dynamic behaviour of the whole bridge. A scaled experimental model of a masonry arch bridge has been built in the laboratory of the Dep. of Structural Engineering at the Politecnico di Torino. The aim was to better understand scour damage scenario and to identify early structural symptoms of pier erosion. A preliminary dynamic identification is carried out on the intact structure and a comparison with the FEM results is performed. The set of identified modal parameters is adopted as the reference system that will be compared with those acquired after the application of damage of increasing extent.

In order to control the IPMC (Ionic Polymer Metal Composite) actuators, it is necessary to use a vision sensing system and a reduced order model from the vision sensing data. In this study, the MROVS (Modal Reduced Order Vision Sensing) model using the least square method has been developed for implementation of the biomimetic motion generation. The simulated transverse displacement is approximated with a sum of the lower mode shapes of the cantilever beam. The NIPXI 1409 image acquisition board and CCD camera (XC-HR50) are used in the experimental setup. Present results show that the MROVS model can efficiently process the vision sensing of the biomimetic IPMC actuator with cost-effective computational time.

To reveal quality change rules and establish the predicting model of konjac vacuum drying, a response surface methodology was adopted to optimize and analyze the vacuum drying process, while an artificial neural network (ANN) was applied to model the drying process and compare with the response surface methodology (RSM) model. The different material thickness (MT) of konjac samples (2, 4 and 6mm) were dehydrated at temperatures (DT) of 50, 60 and 70 °C with vacuum degrees (DV) of 0.04, 0.05 and 0.06 MPa, followed by Box–Behnken design. Dehydrated samples were analyzed for drying time (t), konjac glucomannan content (KGM) and whiteness index (WI). The results showed that the DT and MT should be, respectively, under 60 °C and 4 mm for quality and efficiency purposes. Optimal conditions were found to be: DT of 60.34 °C; DV of 0.06 MPa and MT of 2 mm, and the corresponding responses t, KGM and WI were 5 h, 61.96% and 82, respectively. Moreover, a 3-10-3 ANN model was established to compare with three second order polynomial models established by the RSM, the result showed that the RSM models were superior in predicting capacity (R2 > 0.928; MSE < 1.46; MAE < 1.04; RMSE < 1.21) than the ANN model. The main results may provide some theoretical and technical basis for the konjac vacuum drying and the designing of related equipment.

Purpose The purpose of this paper is to investigate the influence of social capital and relationship quality on key account management (KAM) effectiveness. Design/methodology/approach Based on the literature, the authors designed a framework that links social capital, relationship quality and KAM effectiveness. Data were collected through a self-administered questionnaire. Using data from a sample of 172 business-to-business supplier firms, the authors examined this model. Findings The research results provide empirical support to the importance of relational aspects of KAM by showing how the relational aspects of relationship quality and social capital influence the effectiveness of the supplier-key account relationship. Originality/value The authors add to the literature on relational KAM by integrating theoretical perspectives on social capital, relationship quality and KAM. They develop a model that investigates the antecedents of the effectiveness of supplier–key account relationships from a relational perspective. The study explains the relationships between six constructs representing social capital (ability, benevolence, integrity, flexibility, information exchange and solidarity) and three constructs representing relationship quality (trust, satisfaction and relationship atmosphere), together with the relationships between these three constructs of relationship quality and KAM effectiveness.

Finite element model updating of structures usually ends up with a nonlinear optimization problem. An efficient optimization technique is proposed firstly, which draws together the global searching capability of chaos-based optimization technique and high searching efficiency of trust-region Newton method. This hybrid approach is demonstrated to be more efficient and prone to global minimum than conventional gradient search methods and random search methods by testifying with three test functions. The optimization problem for model updating using modal frequencies and modal shapes is formulated, and a procedure to update the boundary support parameters is presented. A modal test was conducted on a beam structure, and the identified mode frequencies are employed to formulate the optimization problem with the support parameters as the updating parameters. The discrepancy between the mode frequencies of the finite element models before and after updating is greatly reduced, and the updated support condition meet quite well with the insight to the devices that form the supports.

To obtain diagnostic results, doctors combine clinical experience and medical knowledge in their diagnosis process. External medical knowledge provides strong support for diagnosis. Therefore, it is worth studying how to make full use of EMRs and medical knowledge in intelligent diagnosis. Objective This study aims to improve the performance of intelligent diagnosis in EMRs by combining medical knowledge. Methods As an EMR usually contains multiple types of diagnostic results, the intelligent diagnosis can be treated as a multilabel classification task. We propose a novel neural network knowledge-aware hierarchical diagnosis model (KHDM) in which Chinese obstetric EMRs and external medical knowledge can be synchronously and effectively used for intelligent diagnostics. In KHDM, EMRs and external knowledge documents are integrated by the attention mechanism contained in the hierarchical deep learning framework. In this way, we enrich the language model with curated knowledge documents, combining the advantages of both to make a knowledge-aware diagnosis. Results We evaluate our model on a real-world Chinese obstetric EMR dataset and showed that KHDM achieves an accuracy of 0.8929, which exceeds that of the most advanced classification benchmark methods. We also verified the model’s interpretability advantage. Conclusions In this paper, an improved model combining medical knowledge and an attention mechanism is proposed, based on the problem of diversity of diagnostic results in Chinese EMRs. KHDM can effectively integrate domain knowledge to greatly improve the accuracy of diagnosis.

The effect of heterogeneity of pressure-volume (PV) behavior of lung units and the effect of the pulsations of the heart on expired N2 following a single breath of O2 were studied mathematically in a model of the lung. The lung was pictured as consisting of three compartments, one of high compliance (HC) and another of low compliance (LC), both affected by cardiac pulsations, and a third, nonoscillatory compartment (NC). Three sigmoid PV curves were assigned to the three compartments, for both acini and airway (generation 10–23), so that total compliance summed up to 200 ml/cmH2O. Bifurcation of NC was at generation 5/6 and that of HC and LC at any chosen generation. A steepness constant, K, was defined to characterize the sharply descending portion of the sigmoid PV curve. For a ratio of the steepness constant for the oscillatory compartments, KHC/KLC = 1, a sloping alveolar plateau was produced. The plateau was concave for KHC/KLC greater than 1 and slightly convex for KHC/KLC less than 1. Cardiogenic oscillations (CO) of the expired N2 were produced by alternate flows from either NC or HC and LC. CO diminished in fast expiration, and a phase shift between the heart pulsation and the CO was seen; both agree with experimental findings.
