Full textAbstract:
As is well known, according to the "new" theory of reference, the reference relation can be carried out by means of rigid designators whose relationship with the object they designate cannot be analyzed away. Moreover, the new theorists claim, the category of proper names in a natural language marks almost invariably rigid designators. In this paper, both claims are rejected. Using distinctions between the referential system (which determines which entities the primitive symbols of language refer to in each possible world) and the identification system (which determines which member of one world is identical with which member of another), and between two types of object identification (public and perspectival), it is argued that the use of a noun phrase as a rigid designator is predicated on the assumption that a language user knows who (or what) the noun phrase refers to in the actual world. The conclusion is that rigid designation is not a conceptually irreducible reference relation, nor are proper names always used as rigid designators.

Abstract A morphosyntactic peculiarity that separates proper names from (most) other noun types is their ability to occur in a special type of plural, called associative plural, whose meaning is X and X’s associated person(s). In this paper, we apply a ‘converging evidence’ methodology to the analysis of associative plurals, by providing a diachronic typology of these plurals through the identification of the more frequent sources of associative plural markers that are attested in a sample of 80 languages, and by looking for emerging constructions for the expression of associative plurality in two corpora of English and Italian, two languages that do not have a grammaticalized way to encode this type of plurality. The analysis will show that associative plurals are likely to grammaticalize from a restricted pool of synchronic sources, and that these sources are mostly indexical sources and sources denoting the plural set, in accordance with the special semantics and referential properties of proper names.

AbstractA classical task of cross-identification of stars taken from different catalogs becomes a non-trivial one in a case of very big catalogs with significant epoch difference and without proper motions. Some new concepts for this problem solution are proposed here. The method discussed was applied for the Guide Star Catalog with the Astrographic Catalogue identification. About 4.3 million stars were identified in both catalogs.

Full textAbstract:
Summary The U.S. legal system increasingly accepts the idea that the confidence expressed by an eyewitness who identified a suspect from a lineup provides little information as to the accuracy of that identification. There was a time when this pessimistic assessment was entirely reasonable because of the questionable eyewitness-identification procedures that police commonly employed. However, after more than 30 years of eyewitness-identification research, our understanding of how to properly conduct a lineup has evolved considerably, and the time seems ripe to ask how eyewitness confidence informs accuracy under more pristine testing conditions (e.g., initial, uncontaminated memory tests using fair lineups, with no lineup administrator influence, and with an immediate confidence statement). Under those conditions, mock-crime studies and police department field studies have consistently shown that, for adults, (a) confidence and accuracy are strongly related and (b) high-confidence suspect identifications are remarkably accurate. However, when certain non-pristine testing conditions prevail (e.g., when unfair lineups are used), the accuracy of even a high-confidence suspect ID is seriously compromised. Unfortunately, some jurisdictions have not yet made reforms that would create pristine testing conditions and, hence, our conclusions about the reliability of high-confidence identifications cannot yet be applied to those jurisdictions. However, understanding the information value of eyewitness confidence under pristine testing conditions can help the criminal justice system to simultaneously achieve both of its main objectives: to exonerate the innocent (by better appreciating that initial, low-confidence suspect identifications are error prone) and to convict the guilty (by better appreciating that initial, high-confidence suspect identifications are surprisingly accurate under proper testing conditions).

Abstract The use of official proper names is regulated by laws that contribute to the social codification and standardization of propria registration. The paper deals with minority language laws concerning the use of proper names of national minorities in Slovakia. The author gives an overview of the laws, or more precisely paragraphs dealing with the use of official anthroponyms, toponyms and names of institutions. In Slovakia, the largest national minority is Hungarian, so the paper gives examples of using the proper names of Hungarians living in Slovakia, that is, from Slovak-Hungarian bilingual municipalities. In an ethnically mixed environment, the variability of the forms of propria increases, since in the official (and non-official) sphere, proper names can be used not only in the state language, but also in the minority language. In bilingual municipalities, bilingual toponyms and names of institutions appear in both languages. Members of national minorities have the option of entering a personal name in the Register Offices in their mother tongue. Minority proper names fulfil an ethno-identification function, they are a source of individual and collective identity.

Abstract The non-Mendelian mutant d48 of Paramecium tetraurelia contains micronuclear wild type A genes, but at autogamy and conjugation proper processing fails and new macronuclei lack A genes. When cloned A genes are injected into the macronucleus of d48, proper processing is restored at the next autogamy; d48 is rescued, becoming permanently wild type. In the present study we have injected portions of the A gene into d48. We find that the ability to rescue extends over a large portion of the gene, with highest activity near a series of 221-bp repeat units in the middle of the gene. Regions outside the A gene are inactive.

Abstract. The problem of root fracture in case of prosthetically restored non-vital teeth is a common concern among clinicians. These fractures are caused by increasing the diameter of the root canal during the endodontic retreatment and occure on the dental arches in both the anterior and posterior area. Such treatment failures lead to extraction, therefore the physician’s goal is to limit as much as possible their occurrence. We used finite element analysis method to find out what type of corono-radicular restoration is more appropriate in order to avoid fractures. We selected two of the most commun posts used in our country: metallic NiCr casted RCR (corono-radicular reconstruction) and prefabricated fiberglass endodontic posts of various diameters and we analyzed the existing tensions in the dental structures that would predispose the root to fracture.

AbstractObjective:A non-recurrent inferior laryngeal nerve is a rare anomaly in which the nerve enters the larynx directly off the cervical vagus nerve, without descending to the thoracic level. It is very susceptible to damage during surgery. This report describes the important pre-operative radiological evaluations and surgical landmarks in a case of a non-recurrent inferior laryngeal nerve, identified during the recently developed technique of robotic thyroidectomy.Case report:A 38-year-old woman presented with suspected papillary microcarcinoma, as indicated by aspiration cytology. Pre-operative computed tomography showed a right aberrant subclavian artery that indicated a possible right non-recurrent inferior laryngeal nerve. Using robotic thyroidectomy methods, it was possible to carefully dissect along the thyroid capsule. The laryngeal entrance point of the right non-recurrent inferior laryngeal nerve (a constant anatomical landmark) was successfully identified via the three-dimensional, high-magnification views provided by the robotic endoscope.Conclusion:With proper knowledge of radiological and surgical anatomy, and the benefits of high-magnification endoscopic views, a non-recurrent inferior laryngeal nerve can be safely preserved during robotic surgery.

This article presents an account of the involvement of forensic anthropology in the investigation of human rights abuses in the modern era, and the difficulties it faces with respect to lack of adequate funding, volatile settings, the presence of unexploded ordnance, corruption in governmental agencies and a lack of good will, absence of support for NGOs and the curtailment of formal judicial proceedings to effect transitional justice. Syria, Iraq, Afghanistan, Spain, Mexico and the Northern Triangle are provided as regional examples of the problems encountered when attempting to conduct forensic anthropological investigations to locate mass graves, retrieve victims and obtain proper identifications. Interventions by various organisations are highlighted to illustrate their assistance to forensic and non-forensic individuals through technical support, training and mentoring in the areas of crime-scene management and identification techniques. Interventions in mass-grave processing when state agencies have failed, the importance of DNA banks and information from family members and witnesses are also presented.

Full textAbstract:
AbstractDamage detection and identification is one of the most important tasks of proper operation of technical objects and structures. It is, therefore, essential to develop efficient and sensitive methods of early damage detection. Delamination is the type of damage occurring in laminated composites that is one of the most dangerous and most difficult to detect. In this paper, the computational study was performed on the numerical data of the modal shapes of laminated composite beams with simulated delaminations in order to detect them using a fractal dimension-based approach. The obtained results allowed for improvement of detection accuracy as compared to previously applied wavelet-based approach. An additional benefit was decreasing the computational time. Basing on the obtained results it is reasonable to consider the presented approach as a promising alternative to currently applied signal processing methods used for supporting non-destructive testing of structures.

AbstractBetter handling of neurological or neurodegenerative disorders such as Parkinson’s Disease (PD) is only possible with an early identification of relevant symptoms. Although the entire disease can’t be treated but the effects of the disease can be delayed with proper care and treatment. Due to this fact, early identification of symptoms for the PD plays a key role. Recent studies state that gait abnormalities are clearly evident while performing dual cognitive tasks by people suffering with PD. Researches also proved that the early identification of the abnormal gaits leads to the identification of PD in advance. Novel technologies provide many options for the identification and analysis of human gait. These technologies can be broadly classified as wearable and non-wearable technologies. As PD is more prominent in elderly people, wearable sensors may hinder the natural persons movement and is considered out of scope of this paper. Non-wearable technologies especially Image Processing (IP) approaches captures data of the person’s gait through optic sensors Existing IP approaches which perform gait analysis is restricted with the parameters such as angle of view, background and occlusions due to objects or due to own body movements. Till date there exists no researcher in terms of analyzing gait through 3D pose estimation. As deep leaning has proven efficient in 2D pose estimation, we propose an 3D pose estimation along with proper dataset. This paper outlines the advantages and disadvantages of the state-of-the-art methods in application of gait analysis for early PD identification. Furthermore, the importance of extracting the gait parameters from 3D pose estimation using deep learning is outlined.

Full textAbstract:
The identification of non-linear systems is an important topic in structural health monitoring of structures undergoing non-stationary behavior. In general, a non-linear or hysteretic response is typical for buildings, bridges, dampers and structural elements not only as a consequence of strong excitations (i. e. earthquake), but also for low to medium loading levels, due to the constitutive behavior of structural elements or joints. This paper focuses on the non-linear identification of a RC beam-column joint, modeled as a SDoF system, subjected to non-stationary loading: the technique used entails the definition of proper instantaneous estimators of the system dynamic properties by using a linear time-varying approximation of the actual system dynamics and representing the structural response in the joint time-frequency domain.

SUMMARY Since the division of the Streptococcus genus into enterococci, lactococci, and streptococci in 1984, many changes in the nomenclature and taxonomy of the Streptococcus genus have taken place. The application of genetic comparisons has improved the proper classification of the different species. The Lancefield system of serogrouping the streptococci by the expression of beta-hemolysis on blood agar plates is still very useful for the identification of streptococci for patient management. The Lancefield grouping system cannot be used in itself for accurate identification of specific beta-hemolytic species, but it can be a useful part of the identification procedure. Except for identification of the “Streptococcus bovis group” of species and Streptococcus suis, Lancefield grouping is of little value in identification of the non-beta-hemolytic streptococci and related genera. In fact, identification of the non-beta-hemolytic species is problematic for conventional as well as commercially available identification procedures. A combination of conventional tests and specific chromogenic tests suggested by several investigators is presented and discussed. Tables are included that suggest tests and procedures to guide investigators attempting to identify all the species.

Full textAbstract:
In Arabic, a pronominal element (PE) (Note 1) appears in almost all copular clause types, specifically the specificational, identificational, and identity clauses, as well as in clauses with a post-copular definite description. It is obligatory in an identity clause consisting of proper nouns and is otherwise optional. However, the PE cannot be used in Arabic predicational clauses. This paper examines the nature of this PE, why it is illicit in the predicational clause and licit in all other types, and why it is obligatory only in the identity clause consisting of proper nouns and is otherwise optional. It suggests that the PE is a realization of the F head (the identity predicate) in the structure of the identity clause. The illicit use of the PE in the predicational clause follows from the presence of predicative expressions in this type of clause. Lastly, it is shown that the PE is obligatory only in an identity clause involving proper nouns to avoid ambiguity, and is otherwise optional.

Full textAbstract:
Proper orthogonal decomposition (POD) is a coherent structure identification technique based on either measured or computed data sets. Recently, POD has been adopted for the analysis of the in-cylinder flows inside internal combustion engines. In this study, stereoscopic particle image velocimetry (Stereo-PIV) measurements were carried out at the central vertical tumble plane inside an engine cylinder to acquire the velocity vector fields for the in-cylinder flow under different experimental conditions. Afterwards, the POD analysis were performed firstly on synthetic velocity vector fields with known characteristics in order to extract some fundamental properties of the POD technique. These data were used to reveal how the physical properties of coherent structures were captured and distributed among the POD modes, in addition to illustrate the difference between subtracting and non-subtracting the ensemble average prior to conducting POD on datasets. Moreover, two case studies for the in-cylinder flow at different valve lifts and different pressure differences across the air intake valves were presented and discussed as the effect of both valve lifts and pressure difference have not been investigated before using phase-invariant POD analysis. The results demonstrated that for repeatable flow pattern, only the first mode was sufficient to reconstruct the physical properties of the flow. Furthermore, POD analysis confirmed the negligible effect of pressure difference and subsequently the effect of engine speed on flow structures.

AbstractDouble-mode RR Lyrae stars (RRd) represent a fundamental testing ground for the theory of stellar pulsation because they play an important role in understanding the interaction between different pulsation modes. In spite of the fact that from an observational point of view the identification of the fundamental (F) and first overtone (IO) periods needs only few periods of light curve coverage (Sandage et al. 1981, Nemec 1985), the theoretical models of double-mode and mixed-mode variables dating back to the original papers of Cox et al. (1983) and Stellingwerf (1975) were not integrated for long enough times to ensure proper mode identification. Recently Kovacs and Buchler (1992) using a standard radiative hydrodynamical code investigated the theoretical properties of RRd stars in more detail. This paper represents a brief description of the results of few cases computed adopting a non-linear, non-local treatment of convective transport, and long integration times to enable positive mode identification.

Full textAbstract:
Non-smooth dynamics of a cantilever beam subjected to a transverse harmonic force and impacting onto a soft obstacle is studied. Upon formulating the equations of motion of the beam, proper attention is paid to identifying the mechanical properties of an equivalent single-degree-of-freedom (SDOF) piecewise linear impacting model. A multi-degree-of-freedom (MDOF) model of the impacting beam is also derived via standard finite elements. An ‘optimal’ identification curve of the obstacle spring rigidities in the two models is obtained by comparing the relevant pseudo-resonance frequencies. The identification is then exploited in the non-linear dynamic regime to get hints on some main, mostly regular, features of non-linear dynamic response of the impacting beam by the actual investigation of the behaviour of the sole equivalent SDOF model, with a definitely lower computational effort. Sample regular and non-regular responses of the MDOF model are also presented where the identification does not work. Overall, useful points are made as regards the possibility and the limitations of referring to an SDOF impacting model to investigate the non-linear response of the underlying infinite-dimensional system.

Full textAbstract:
Prefabricated power support structure foundations are made in prefabrication plants where concrete is laid in layers in moulds. The quality of the prefabricated units depends mainly on proper concrete mixture compaction, which is usually effected by means of immersion vibrators. It happens that when the vibrator is withdrawn too quickly, defects, in the form of, e.g., air voids and zones of insufficiently vibrated concrete, appear. Modern non-destructive acoustic techniques, which in recent years have been increasingly commonly used in the construction industry, are highly suitable for testing concrete elements, particularly prefabricated concrete units. The non-destructive impact-echo technique is particularly useful for determining defect location depth and for locating defective areas.

ABSTRACT Outer dense fiber 2 (Odf2) was initially identified as a major component of sperm tail cytoskeleton and later was suggested to be a widespread component of centrosomal scaffold that preferentially associates with the appendages of the mother centrioles in somatic cells. Here we report the identification of two Odf2-related centrosomal components, hCenexin1 and hCenexin1 variant 1, that possess a unique C-terminal extension. Our results showed that hCenexin1 is the major isoform expressed in HeLa cells, whereas hOdf2 is not detectably expressed. Mammalian polo-like kinase 1 (Plk1) is critical for proper mitotic progression, and its association with the centrosome is important for microtubule nucleation and function. Interestingly, depletion of hCenexin1 by RNA interference (RNAi) delocalized Plk1 from the centrosomes and the C-terminal extension of hCenexin1 was crucial to recruit Plk1 to the centrosomes through a direct interaction with the polo-box domain of Plk1. Consistent with these findings, the hCenexin1 RNAi cells exhibited weakened γ-tubulin localization and chromosome segregation defects. We propose that hCenexin1 is a critical centrosomal component whose C-terminal extension is required for proper recruitment of Plk1 and other components crucial for normal mitosis. Our results further suggest that the anti-Odf2 immunoreactive centrosomal antigen previously detected in non-germ line cells is likely hCenexin1.

AbstractThe proper and efficient operation of the Hipparcos satellite requires positions within 1.5 arcsec at the 1989 epoch for the 100-120 000 programme stars. The first steps of the preparation have been the identification of the proposed stars in the well-known astrometric catalogues and the output of successive lists of ‘non-astrometric’ stars not belonging to these catalogues. Ground-based observations needed to supplement the presently available data, which are now under way, are also described.

Full textAbstract:
The paper describes the results of a measurement campaign to characterize the non-intentional emissions (NIE) that are present in the low voltage section of the electrical grid, within the frequency range assigned to narrowband power line communications (NB-PLC), from 20 kHz to 500 kHz. These NIE may severely degrade the quality of the communications and, in some cases, even isolate the transmission devices. For this reason, the identification and characterization of these perturbations are important aspects for the proper performance of the smart grid services based on PLC. The proper characterization of NIE in this frequency range is a key aspect for the selection of efficient configurations to find the best trade-off between data throughput and robustness, or even for the definition of new improved error detection and correction methods. The huge number of types of NIE, together with the wide variety of grid topologies and loads distribution (density and location of homes and industrial facilities) are great challenges that complicate the thorough characterization of NIE. This work contributes with results from field trials in different scenarios, the identification of different types of NIE and the characterization both in time and frequency domains of all the registered disturbances. This contribution will be helpful for a better knowledge of the electrical grid as a transmission medium for PLC and, therefore, for evaluating the appropriateness of different robustness techniques to be applied in the next generation of smart grid services.

Due to significant increment in harmonic polluting loads in the power system, there has been enhanced attention of the power professionals towards the estimation of harmonic signals and identification of their sources in the system. Harmonic source identification is an important step for proper accountability, monitoring, and mitigation of any harmonic pollution. The active power direction (APD) method is one of the conventional approaches for harmonic source detection in the distribution system. Although it is simple and easy to implement, serious concerns were raised on its validity, as the direction of active power is dependent on the phase angle. In this paper, APD is augmented with distorting and non-distorting power to improve its accuracy and reliability for harmonic source identification. The distorting and non-distorting portions of the loads are separated, and the distorting and non-distorting powers are calculated at each node. These calculated powers, in addition to the direction of the harmonic active power, are used to formulate the logic required for deciding the severity index at each node. The validity of the method has been tested on a single-phase network, an IEEE-5 bus system, and an IEEE-14 bus system. It has been observed that the proposed method provides good results than conventional APD with the same measurement requirement.

Full textAbstract:
<p style="text-align: justify;">An empirical investigation of elementary school teacher candidates on classification activities dealing with animate and inanimate objects in terms of being living or non-living demonstrates that as the size of the objects increases, subjects are more likely to classify them correctly as either being an animal or having living characteristics. Despite a variety of misconceptions having an impact on the results, size magnitude is shown to play a significant role on proper classification. The subjects’ performance on these activities at an advanced stage of their preparation suggests that their factual and procedural knowledge are deficient due to a lack of opportunities for conceptual development of the items tested. The identification of the role of size on the proper classification of objects in the activities bears significantly on the science curricular structure at the elementary school level. As the results of this study indicate, both pre-service elementary school teachers and by extension their prospective students need longer practice dealing with living and non-living classification activities, particularly in tasks where the microscopic features of matter can be investigated so that the proclivity to regard size as the defining characteristic is effectively addressed.</p>

The near infrared spectroscopy is widely used in the different industries as a rapid, non-invasive analitical tool. It is suitable for identification, qualification and quantitative analysis as well. As this technique is indirect, to make accurate calibration equations we need a proper sample population. Before the quantitaive analysis, developing calibiration modells we have to collect and examine the spectra. In our study we examined wheat samples with known origins to find if there is any effect of the growing area on the NIR spectra.

AbstractThis article contributes to the discussion about proper product safety in the wake of disruptive digital technologies. By picking the example of 3D printing we analyse why incumbent product liability law does not incentivise optimal deterrence of harmful 3D printed products. We identify the new business models associated with 3D printing as the main trigger for the non-applicability of incumbent liability law. The new business models are characterised by making no strong reference to economies of scale. As a result, the informational content of specific producers and their products is scarce and the identification of tortfeasors becomes a challenge for the legal system. While there is yet no easy solution to the problem, we provide at the end of the article an inventory of institutions that may take the lead in finding new proper liability rules and safety regulations.

Full textAbstract:
Urine color is an indicator of health status, especially for patients undergoing medical intervention treatment of urinary catheterization. Urinary tract infections are the most frequently developed infections among patients receiving treatment in medical institutions. Such infections can be detected from urine color, like in the case of the purple urine bag syndrome. However, it is a difficult task for non-nursing care staff and even the nursing staff to correctly conduct naked-eye identification without proper tools. To better assist both nursing and non-nursing care staff with the detection of infection signs in urine bag patients, a urine color automatic identification device has been developed. The device is based on microcontroller framework and color quantization algorithm. A hybrid color quantization algorithm and two features were proposed to identify the urine color. The identified color, as query data instead of human-described color keyword, can be used to retrieve the information from the database and then find possible symptoms for early warning. Instead of the nursing staff, the device can automatically identify the patient's urine color. From experimental results, the device with the proposed algorithm shows its capability and feasibility of the urine color automatic identification.

Background: In its early development, radar (radio detection and ranging) was primarily used by the navy, the military, and the aviation services, as well as space organizations for security and monitoring purposes. Nowadays, the demand of radar is expanding. Research has been conducted to overcome the limitations of radar.Objective: One of the current limitations to detect moving object. The current paper aims to fill the gap in the literature by using a radar system in the identification of moving object, capturing the distance, direction, radar pulse duration and object shape simultaneously. Velocity or the object’s speed towards or away from the radar was determined by using an algorithm to obtain the precision.Methods: The accuracy of distance measurement and angle is ensured by comparing the real values and the values obtained by the radar. The objects under study consist of metal and non-metal. Novelty of this work is the accurate detection of moving objects with suitable algorithms using only one Arduino UNO and one ultrasonic sensor.Results: The experiment design yielded much better efficiency than previous works. The proposed method predicted the exact speed of the object detected by the radar system. The experiment has successfully proven the accuracy of moving object sensor.Conclusion: Besides proper distance and velocity, a large set of data was taken to find the accuracy of the radar for objects of different shapes. For a cylindrical object, the radar provided 100% efficiency in a constant environment when the object was 5 cm away. The accuracy decreased to 30% when the distance was 17 cm away. The limitation of this system is that it was unable to detect small object or if the object was very close (1 cm).

AbstractGenerally, the Force-State Mapping (FSM) is an effective method to identify the parameters of nonlinear joints provided that the joint model is exactly known in advance. However, the variation of the non-linear joints is so large that the mathematical models of non-linear joints generally are not known in advance. Therefore, the model and the parameters of a non-linear joint should be identified simultaneously in practice. In this work, a new identification procedure which was based on the FSM method in frequency domain was proposed to identify the mathematical model and parameters of a non-linear joint simultaneously. Generally, there are many feasible combinations of models and parameters which can satisfy the measurement data within an allowable range of error. In this work, an iteration procedure was used to update the feasible models to result in an optimal model with its parameters. The simulation results show that a proper mathematical model and accurate parameters can be identified simultaneously by the new procedure even that the measurement data are contaminated by noise.

Advanced esophageal cancer is known to have a poor prognosis. The early detection of esophageal neoplasms, including esophageal dysplasia and early esophageal cancer, is highly important for the accurate treatment of the disease. However, esophageal dysplasia and early esophageal cancer are usually subtle and can be easily missed. In addition to the early detection, proper pretreatment evaluation of the depth of invasion of esophageal cancer is very important for curative treatment. The progression of non-invasive diagnosis via image-enhanced endoscopy techniques has been shown to aid the early detection and estimate the depth of invasion of early esophageal cancer and, as a result, may provide additional opportunities for curative treatment. Here, we review the advancement of image-enhanced endoscopy-related technologies and their role in the early identification of esophageal neoplasms.

Abstract An approach to estimation of a parametric discrete-time model of a process in the case of some a priori knowledge of the investigated process properties is presented. The knowledge of plant properties is introduced in the form of linear bounds, which can be determined for the coefficient vector of the parametric model studied. The approach yields special biased estimation of model coefficients that preserves demanded properties. A formula for estimation of the model coefficients is derived and combined with a recursive scheme determined for minimization of the sum of absolute model errors. The estimation problem of a model with known static gains of inputs is discussed and proper formulas are derived. This approach can overcome the non-identifiability problem which has been observed during estimation based on measurements recorded in industrial closed-loop control systems. The application of the proposed approach to estimation of a model for an industrial plant (a water injector into the steam flow in a power plant) is presented and discussed.

Full textAbstract:
Proper investment in mushroom production (farming and wild mushroom picking activities) may represent a winning strategy for many countries, including Italy, to better face the problems of food security and environmental impact, and to break away from imports, enhancing the local products. However, the risk related to the consumption of poisoning species requires governments to implement or reinforce effective control measures to protect consumers. Mushroom identification by phenotype observation is hardly applicable if morphologically-similar species, non-whole specimens, or clinical samples are involved. Genotypic analysis is a valid alternative. An ongoing research project involving the Experimental Zooprophylactic Institute of Lazio and Tuscany, the regional Mycological Inspectorate, the Tuscany Mycological Groups Association, and the Department of Veterinary Sciences of the University of Pisa aims to reinforce the collaboration among institutions for the management of mushroom poisoning. The core’s project aims to develop an internal genetic database to support the identification of wild and cultivated mushroom species in the Italian territory. The database will include Internal Transcribed Spacer (ITS) sequences retrieved from official databases (the NCBI GenBank and the BOLD system) which are considered to be reliable, after a proper selection process, and sequences from specimens collected directly and identified by expert mycologists. Once it is validated, the database will be available and further implementable by the official network of national laboratories.

In the design and realisation process of the linear objects it is extremely important to identify ground properties and specify the extent of the complexity of hydrogeological conditions. Aiming at detailed site identification as well as proper discontinuity and anomaly detection is impossible in the light of the point character of geotechnical investigations. In order to deal successfully with such impediments, various non-invasive geophysical methods, including the ground penetrating method, are worth using. The analysis carried out proves that the GPR technique can be used for illustrating the boundaries of the organic layers in the subsoil.

Full textAbstract:
ABSTRACT Legionella pneumophila, a causative agent of bacterial pneumonia, survives inside phagocytic cells by avoiding rapid targeting to the lysosome. This bacterium utilizes a type IVB secretion system, encoded by the dot/icm genes, to replicate inside host cells. DotL, a critical component of the Dot/Icm secretion apparatus, functions as the type IV coupling protein. In contrast to most dot/icm genes, which are dispensable for growth on bacteriological media, dotL is required for the viability of wild-type L. pneumophila. Previously we reported that ΔdotL lethality could be suppressed by inactivation of the Dot/Icm complex via mutations in other dot/icm genes. Here we report the isolation of non-dot/icm suppressors of this phenotype. These ΔdotL suppressors include insertions that disrupt the function of the L. pneumophila homologs of cpxR, djlA, lysS, and two novel open reading frames, lpg0742 and lpg1594, that we have named ldsA and ldsB for lethality of ΔdotL suppressor. In addition to suppressing ΔdotL lethality, inactivation of these genes in a wild-type strain background causes a range of defects in L. pneumophila virulence traits, including intracellular growth, implicating these factors in the proper function of the Dot/Icm complex. Consistent with previous data showing a role for the cpx system in regulating expression of several dot/icm genes, the cpxR insertion mutant produced decreased levels of three Dot/Icm proteins, DotA, IcmV, and IcmW. The remaining four suppressors did not affect the steady-state levels of any Dot/Icm protein and are likely to represent the first identified factors necessary for assembly and/or activation of the Dot/Icm secretion complex.

Full textAbstract:
Fault management (FM) performance and information sampling behavior were examined while participants operated a complex micro-world that simulated system failures within a generic life-support system of a spacecraft. One group of participants was supported by an integrated display that facilitated fault identification while the other group had to rely on separated raw data readings. The effects of two modes of intelligent automation support were also examined. At a low level of automation (LOA), fault identification was generated along with an advisory on a sequence of recovery actions to be implemented manually at the operator's discretion. The higher LOA generated fault identification but allowed the operator a veto against automatic implementation of the suggested recovery plan. Automated fault identification was unreliable 30% percent of the time; in these trials the automation missed fault identification, gave a false alarm to a nominal situation, or provided false or incomplete fault identification. Initiation of proper recovery when the automation failed was less accurate and slowest when operators were supplied with the non-integrated display, but only when they operated at the low LOA mode prior to the failure. This effect was associated with superior information sampling behavior at the higher LOA when automation was reliable. Display integration and the higher LOA thus supported more efficient sampling of fault relevant displays thereby, promoting better fault state awareness in the presence of reliable automation. This also benefited fault management when the automation failed.

Introduction: LCK gene, also known as lymphocyte-specific proto-oncogene, is expressed in lymphocytes, and associated with coordinated expression of MHC class I and II in response to physiological stimuli, mediated through a combined interaction of promoters, suppressors, and enhancers. Differential usage of LCK promoters, transcribes dysfunctional transcript variants leading to leukemogenesis and non-induction of MHC class I gene variants. Viruses use C-type lectins, like CD209, to penetrate the cell, and inhibit Pattern Recognition Receptors (PRR), hence evading immune destruction. Given that Ebolavirus (EBOV) disease burden could result from a dysfunctional LCK pathway, identification of the genetic pathway leading to proper immune induction is a major priority. Methods: Data for EBOV related virus samples were obtained from Gene Expression Omnibus database and RMEAN information per gene per sample were entered into a table of values. R software v.3.3.1 was used to process differential expression patterns across samples for LCK, CD209 and immune-related genes. Principal component analysis (PCA) using ggbiplot v.0.55 was used to explain the variance across samples. Results: Data analyses identified three viral clusters based on transmission patterns as follows: LCK-CD209 dependent, LCK-dependent specific to EBOV, and CD209 dependent. Compared to HLA class II gene variants, HLA class I (A, B and C) variants were <2 fold expressed, especially for EBOV samples. PCA analyses classified TYRO3, TBK1 and LCK genes independent of the data, leading to identification of a possible pathway involving LCK, IL2, PI3k, TBK1, TYRO3 and MYB genes with downstream induction of immune T-cells. Discussion: This is the first study undertaken to understand the non-functional immune pathway, leading to EBOV disease pathogenesis and high fatality rates. Our lab currently exploits, through cutting edge genetic technology to understand the interplay of identified genes required for proper immune induction. This will guide antiviral therapy and possible markers for viral disease identification during outbreaks.

Abstract Context.—Acute leukemia displays characteristic patterns of surface antigen expression (CD antigens), which facilitate their identification and proper classification and hence play an important role in instituting proper treatment plans. In addition to enzyme cytochemical analysis, multiparameter flow cytometric analysis has become commonplace in most laboratories for that purpose. The essential role and caveats of flow cytometry in that regard, however, have received little scrutiny. Objective.—To evaluate the expression of commonly used immunomarkers and patterns in various acute leukemias to help define the best use and role of multiparameter flow cytometry in the diagnosis and proper classification of acute leukemias. Design.—We have retrospectively analyzed the immunophenotypic data from 508 de novo adult and pediatric acute leukemia patients, as studied using multiparameter flow cytometry in addition to routine morphologic and enzyme cytochemical analysis. Cytogenetic and/or molecular data were correlated in all 41 cases of acute promyelocytic leukemia (APL) and in 203 other cases of acute leukemia where those data were available. We have also determined the positive and negative predictive values of a combined CD34 and HLA-DR expression pattern for the differentiation of APL from other myeloid leukemias. Results.—In acute myeloid leukemia (AML) other than APL, expression of CD34 was seen in 62% and expression of HLA-DR in 86% of all cases. Twenty-six (10%) of 259 cases of non-APL AML were negative for both CD34 and HLA-DR as opposed to 33 (80%) of 41 cases of APL. None of the cases of APL were positive for both CD34 and HLA-DR in contrast to 149 (58%) of 259 cases of non-APL AML. Fifty-three cases were found to be examples of minimally differentiated AML (AML M0) based on the lack of expression of cytoplasmic CD3 and cytoplasmic CD79a and expression of one or more myelomonocytic-associated antigens and/or myeloperoxidase. Expression of CD20 was seen in 40 (24%) of 168 cases of precursor B-cell acute lymphoblastic leukemia (pB-ALL) and 52 (29%) lacked CD34 expression. Five of 180 cases of pB-ALL and 2 cases of precursor T-cell ALL (pT-ALL) were negative for terminal deoxynucleotidyl transferase (TdT). Aside from cytoplasmic CD3, CD5 and CD7 were the most sensitive antigens present in all 21 cases of pT-ALL. CD33 was more sensitive but less specific than CD13 for myeloid lineage. Conclusion.—Aside from identification of blasts, flow cytometry was found to be especially useful in the correct identification of AML M0, differentiation of APL from AML M1/M2, and correct identification of TdT-negative ALL and unusual variants, such as transitional B-cell ALL and undifferentiated and biphenotypic acute leukemias.

Biosurfactants are amphiphilic compound, having hydrophilic and hydrophobic moieties enabling them to reduce surface and interfacial tension at the surface. Their unique properties are applied in various industries such as foaming and wetting agents, emulsifiers, detergents and bioremediation. A total of 98 isolates showed biosurfactant activity using hemolytic activity, drop collapse test and oil spreading assay. All isolates were rod-shaped, Gram positive and majority of them were non-endospore former. Only the isolates showing the highest percentage of emulsification index (E24) and ability to reduce tension were used for species identification using 16S rDNA gene sequencing which were isolates A1(6) and A2(1). Both isolates were identified as Bacillus sp. cp-h50 and Bacillus sp. XT-24 respectively, rod-shaped, endospore former and Gram positive. The biosurfactant produced by both species showed high emulsification index (E24) (A1(6), 63.3% and A2(1), 46.7%) and good surfactant capacity. The size of amplified gene of 16S rDNA gene was approximately 1.5 kb. These features provide evidence that both species could be a potential biosurfactant producer with proper optimization for the production of biosurfactant. The biosurfactant produced by both bacterial species were identified as surfactin using Fourier Transform Infrared Spectroscopy (FTIR).

This paper investigates the use of fractal geometry for analyzing ECG time series signals. A technique of identifying cardiac diseases is proposed which is based on estimation of Fractal Dimension (FD) of ECG recordings. Using this approach, variations in texture across an ECG signal can be characterized in terms of variations in the FD values. An overview of methods for computing the FD is presented focusing on the Power Spectrum Method (PSM) that makes use of the characteristic of Power Spectral Density Function (PSDF) of a Random Scaling Fractal Signal. A 20 dataset of ECG signals taken from MIT-BIH arrhythmia database has been utilized to estimate the FD, which established ranges of FD for healthy person and persons with various heart diseases. The obtained ranges of FD are presented in tabular fashion with proper analysis. Moreover, the experimental results showing comparison of Normal and Abnormal (arrhythmia) ECG signals and demonstrated that the PSM shows a better distinguish between the ECG signals for healthy and non-healthy persons versus the other methods.

Full textAbstract:
In this paper, a non-Lyapunov novel approach is proposed to estimate the unknown parameters and orders together for noncommensurate and hyper fractional chaotic systems based on cuckoo search oriented statistically by the differential evolution (CSODE). Firstly, a novel Gaos’ mathematical model is proposed and analyzed in three submodels, not only for the unknown orders and parameters’ identification but also for systems’ reconstruction of fractional chaos systems with time delays or not. Then the problems of fractional-order chaos’ identification are converted into a multiple modal nonnegative functions’ minimization through a proper translation, which takes fractional-orders and parameters as its particular independent variables. And the objective is to find the best combinations of fractional-orders and systematic parameters of fractional order chaotic systems as special independent variables such that the objective function is minimized. Simulations are done to estimate a series of noncommensurate and hyper fractional chaotic systems with the new approaches based on CSODE, the cuckoo search, and Genetic Algorithm, respectively. The experiments’ results show that the proposed identification mechanism based on CSODE for fractional orders and parameters is a successful method for fractional-order chaotic systems, with the advantages of high precision and robustness.

Computational modelling of the crack growth in brittle and quasi-brittle materials used in mechanical, civil, etc. engineering applies the cohesive zone model with various traction separation laws; determination of micro-mechanical parameters comes then from static tests, microscopic observation and numerical calibration. Although most authors refer to ill-possedness and need of artificial regularization in inverse problems (identification of material parameters), some difficulties originate even in nonlinear formulations of direct and sensitivity problems. This paper demonstrates the possibility of proper analysis of the existence of a weak solution and of the convergence of a corresponding numerical algorithm for such model problem, avoiding non-physical assumptions.

Abstract The expression of ad hoc categories ranges from discourse-level to syntactic and morphological strategies. Considering derivation in particular, it has been observed that also collective suffixes can be used for the identification of context-dependent sets. The aim of this paper is to investigate the relation between collectives and ad hoc categories by focusing on the Italian suffix -aglia and by discussing its diachronic relation with the Latin neuter nouns ending in -ālia. The discussion concerning the notion of collective will take into account a recent proposal that distinguishes between collective nouns, aggregate nouns, and superordinates. As will be shown, aggregate nouns are of particular interest for interpreting some Latin pluralia tantum in -ālia that denote sets of heterogeneous entities with similar properties. The same possibility to derive aggregate nouns characterizes the suffix -aglia that, when attached to proper nouns, can also convey associative meanings, or denote categories including persons and situations that share the named exemplar as a common denominator. As the analysis will show, the development of these functions correlates with the mechanisms of (inter)subjectification.

Since the amount and quality of experimental ‘omics’ data continue to increase rapidly, there is great need for methods for proper model building which can handle this complexity. In the present chapter we review two key steps of the model building process, namely parameter estimation (model calibration) and optimal experimental design. Parameter estimation aims to find the unknown parameters of the model which give the best fit to a set of experimental data. Optimal experimental design aims to devise the dynamic experiments which provide the maximum information content for subsequent non-linear model identification, estimation and/or discrimination. We place emphasis on the need for robust global optimization methods for proper solution of these problems, and we present a motivating example considering a cell signalling model.

As the first mass of land in Vietnam becoming a French colony, Nam Ky – the Southern part of Vietnam (currently renamed Nam Bo – the South of Vietnam) was affected, earliest and hardest, by the consequences of colonialism. Brutal governance mechanism; plundering ruses to fully exploit profit; policies of enslavement, for obscurantism, and cultural intoxication; etc. are all sinful acts and evil nature of colonialism which the Vietnamese people as well as the entire advanced humankind have fought against and eradicated. However, it would be full of prejudices, non-objective and one-sided to totally deny important impacts for the evolutional process of the nation’s history in a number of economic sectors that the colonial exploitation has brought, if temporarily excluding its driving force and purpose. Therefore, study of the process, characteristics and consequences of the policy to exploit colonies in the Southern part of Vietnam is to contribute to sound recognition of historical heritages during colonial times, also to better understand our socio-economic starting point 100 years, more or less, ago; so as to reach proper selection and inheritance in the mission of fostering industrialization and modernization for and towards today’s sustainable development strategy.

Background: Ovarian lesions are quite common among females of all age groups. Ovarian cancers account for 6% of female malignancy. Ultrasonography (USG) can help in proper identification and categorization of these lesions. Fine Needle Aspiration Cytology (FNAC) under USG guidance can be an effective modality for early diagnosis of ovarian masses. Aims And Objectives: To evaluate the role of USG guided FNAC over ovarian space occupying lesions (SOLs) for proper categorization into non-neoplastic, benign & malignant variants and to identify possible underlying causes of cytological misdiagnosis, if any, in comparison to histopathological diagnosis. Materials and Methods: FNAC under USG guidance were performed over one hundred and sixteen cases with radiologically proved ovarian SOLs during a period of five years. Aspirated materials were interpreted as non- neoplastic, benign or malignant lesions. Histopathological study was possible in 47 of these cases. Results: Out of 116 aspirations, non-neoplastic, benign and malignant diagnosis were given in 51, 42 & 23 cases, respectively. During histopathological correlation 41 out of 47 cases (87.2%) show exact cytohistological parity. Rest six cases with cytological misdiagnosis were discussed in detail. Conclusion: USG guided FNAC can effectively diagnose ovarian lesions in more than 87% cases. Scrutiny about failed diagnosis will help to improve accuracy in future.
