Application of Current Transformers in Power Electronics Converters with Voltage Feedback

The article presents a solution through a current transformer (or a transformer that operates in current mode), which provides galvanic separation of the signal between the control unit and the power unit, in power electronic converters. The design of this specific current transformer is introduced. The magnetic core of the current transformer is chosen to be toroidal. The design recommendations for selecting the appropriate magnetic core material are discussed. The soft magnetic materials as nanocrystalline materials and amorphous alloys with flat hysteresis loops meet the design requirements. The errors of the current transformer are estimated. Some other specific applications of current transformers are also presented.

An integrative study of social and reproductive systems in northern bobwhite (Colinus virginianus)

Northern Bobwhite (Colinus virginianus) inhabit variable environments. Individual behavior likely arose to address this environmental variability. Specific, resulting actions of bobwhites include group living, brood amalgamation, and breeding. I investigate these behaviors by integrating techniques from field and molecular biology to examine the effects of relatedness on individual cooperation and quantify the breeding behavior of bobwhites. My results suggest that kin selection does not affect bobwhite behavior and bobwhite may adopt behavioral strategies, flexibly expressed in the presence of environmental variation, to maximize individual fitness.

A Novel Low-Jitter Interface for Synchronization with Low-Cost Integrated IEEE802.11 Chips

This paper presents a novel low-jitter interface between a low-cost integrated IEEE802.11 chip and a FPGA. It is designed to be part of system hardware for ultra-precise synchronization between wireless stations. On physical level, it uses Wi-Fi chip coexistence signal lines and UART frame encoding. On its basis, we propose an efficient communication protocol providing precise timestamping of incoming frames and internal diagnostic mechanisms for detecting communication faults. Meanwhile it is simple enough to be implemented both in low-cost FPGA and commodity IEEE802.11 chip firmware. The results of computer simulation shows that developed FPGA implementation of the proposed protocol can precisely timestamp incoming frames as well as detect most of communication errors even in conditions of high interference. The probability of undetected errors was investigated. The results of this analysis are significant for the development of novel wireless synchronization hardware.
Music Source Separation Using Generative Adversarial Network and U-Net

The separation of sound sources in the decomposition of music has become an interesting problem among scientists for the last 50 years. It has the main target of making it difficult for components in the music, such as vocals, bass, drums, and others. The results of sound separation have also been applied on many fields, such as remixing, repanning, and upmixing. In this paper, a new model based on a Generative Adversarial Network (GAN) is proposed to separate the music sources to rebuild the sound sources that exist in the music. The GAN architecture is built using U-net with VGG19 as an encoding block, mirror from VGG19 as an encoder block on the generator, and three times combinations of Convolution, Batch Normalization, and Leaky Rectified Linear Unit (LeakyReLU) blocks. An evaluation using the DSD100 dataset shows that the proposed model gives quite high average source to distortion ratios (SDR): 7.03 dB for bass, 18.72 dB for drums, 20.20 dB for vocal, and 12.73 dB for others.
It's so Real: Psychophysiological Reaction towards Virtual Reality Exposure

Virtual reality (VR) technology has been utilized in various types of scientific fields. In psychology, VR is used as an alternative intervention particularly exposure therapy, in which therapists often have difficulties in maintaining client confidentiality and security when confronting them with feared situations, especially in public places. VR allows therapist to present a three-dimensional stimulus virtually, so that the risks of safety can be minimized. This study aimed to explore the effect of height stimulus presented with VR technology on physiological and psychological reactions. The research method used was a non-random pre-test and post-test experiment. Physiological reactions were measured using the ProComp5 Infiniti biofeedback system with three sensors: heart rate, respiratory rate, and skin conductance. Participants were confronted with a height environment simulated through a Head-mounted display (HMD) Oculus Rift Development Kit 2. The results indicated that there were changes in their psychological and physiological reactions. It could be concluded that exposure through VR, which is very close to brain’s information processor accompanied by various sensory stimuli, is able to create conditions where individuals can really feel as if being at a real height. Changes in psychological and physiological reactions are discussed in this paper.
An assessment of the in-vitro multiplication rates of fourteen black currant cultivars

SummaryThe in-vitro multiplication rates of fourteen black currant (Ribes nigrum) cultivars from a range of geographical origins were compared. Shoot tips and axillary buds were cultured for 21 days in a medium supplemented with 2.2 mg l−1 6-benzylaminopurine. The highest shoot multiplication rate achieved was by cv. Ben Lomond, where the mean rate was 3.53 shoots from a single initial expiant. Mean rates between 1.50 and 3.33 were obtained from other cultivars. The results are discussed in relation to the parentage of each cultivar.
Enhanced Ultraviolet Spectroscopy by Optical Clearing for Biomedical Applications

In this paper, we describe the combination of ultraviolet (UV) spectroscopy with the optical clearing technique to induce new tissue windows, evaluate their efficiency, study the diffusion properties of agents and discriminate cancer. The use of highly concentrated glycerol solutions has induced high efficiency clearing effects in the UV, both in human colorectal and gingival tissues. The protein dissociation rate obtained for colorectal tissues was approximately 3 times higher in pathological than in normal mucosa and the kinetics of diffuse reflectance in the UV allowed to estimate the diffusion coefficient for water in gingival mucosa at glycerol action as (1.78 ± 0.26) × 10−6 cm2/s.
Developments in X-Ray Contrast Media and the Potential Impact on Computed Tomography

Abstract Over the past 120 years, continuous developments in medical imaging has improved diagnosis and treatment for many diseases and has thereby improved treatment outcome and quality of life of many patients. The number of computed tomography (CT) examinations is today increasing by 4% per year worldwide, for a total of approximately 300 million CT scans per year. About 40% of CT scans are contrast enhanced. Intravenous iodinated contrast media are commonly used for contrast enhancement in CT scans to evaluate diseases and determine treatment response. The current gold standards for intravenous x-ray contrast media in CT or interventional angiography are iodinated low- and iso-osmolar compounds such as iopromide, iohexol, or iodixanol. Both classes have similar and favorable efficacy and safety profiles. Although iodine is biologically inert, iodinated contrast media can cause adverse reactions. In the future, one possibility would be to develop iodine-free contrast media that are better suited to higher x-ray tube voltage ranges, allowing greater flexibility for scanning protocols and thus leading to techniques that can provide equivalent diagnostic value at lower doses of radiation. Iodine-free contrast media would in addition provide an alternative to the market standard that could offer benefits for patients with known reactions to low-osmolality contrast media or thyroid disorders. The development of a new contrast medium, however, needs to be put in context with all upcoming technological advances in x-ray and CT. New detector technologies and artificial intelligence algorithms will in the future also improve the CT image reconstruction enabling the reduction of contrast media and radiation doses.
SLE: reconciling heterogeneity

Patients with SLE experience multiple, varied symptoms and laboratory abnormalities that occur in different combinations, at different points in time.1 A result of the heterogeneity is that studies on SLE employ several, sometimes conflicting, definitions of the illness. Investigators disagree about when SLE begins; how SLE relates to similar and overlapping rheumatic illnesses; whether SLE-like illnesses of known genetic causes count as SLE; and whether the same diagnosis name should apply when investigators describe stratified populations, for instance, SLE with and without renal disease. Inconsistent definitions lead stakeholders—patients, practising physicians, administrators, epidemiologists and investigators—to count different patients and to develop different opinions about the mechanisms and treatment of SLE. To advocate a consensus vocabulary and conceptual model, in this paper we deconstruct the process of making a diagnosis of SLE by examining its classification and diagnostic criteria, definitions and illness models. We discuss the ways by which stratification biases conclusions and how the purpose for which a stakeholder names a diagnosis determines whom they accept as having this disease. ### Classification and diagnostic criteria When in the mid-19th century Cazenave first used the name lupus erythematosus , SLE was a rare and life-threatening illness.2 3 A century later, as new technologies identified more patients,4–10 physicians found SLE to be more clinically diverse, and often less severe, than they once believed. To improve homogeneity of patient populations identified for clinical studies, investigators developed classification criteria that are specific, binary (SLE is present or not) and time limited (valid only for the extent of a study). The homogeneity of classification criteria is implied but not real. The American College of Rheumatology (ACR) criteria allow 330 different combinations of symptoms and laboratory tests to affirm a diagnosis of SLE.11 Classification criteria are insensitive; they exclude patients who, despite disabling and treatable symptoms, fall below …
A new species of Pagurixus Melin, 1939 (Crustacea, Decapoda, Anomura, Paguridae) from the Ryukyu Islands, Japan

A new species of the hermit crab genus Pagurixus Melin, 1939, P. patiae n. sp. , is described from intertidal reef fl at of Iriomote Island, Yaeyama Islands of southern Ryukyu Islands, Japan. Morphological similarity suggests that the new species is allied to P. laevimanus (Ortmann, 1892) and P. anceps (Forest, 1954). However, the notably dissimilar fourth pereopods immediately distinguishes P. patiae n. sp. from P. laevimanus and P. anceps. Furthermore, characters of the cheliped, ambulatory legs and/or coloration in life also separate P. patiae n. sp. from the latter two species.
Inter-and Intraspecific Variation of the Nucleotide Sequence of the Cytochrome b Gene in Cory's (Calonectris diomedea), Manx Shearwater (Puffinus puffinus) and the Fulmar (Fulmavus glacialis)

Abstract Cytochrome b, DNA Sequence, Polymerase Chain Reaction (PCR), Molecular Evolution, Procellariidae The cytochrome b gene of three European taxa of the family of Procellariidae was amplified from total DNA and sequenced. The sequence comparison shows that the Fulmar (Fulmarus glacialis) is significantly distinct from shearwaters, whereas Cory’s (Calonectris diomedea) and Manx Shearwater (Puffinus puffinus) are closely related. Although the populations of C. diomedea can be distinguished morphologically, the sequences of cyt b differ only slightly between the Atlantic and Mediterranean subspecies (i.e. C. d. borealis versus C. d. diomedea) and do not reveal other population differences within subspecies.
Integrating Geohazard Demand And Structural Capacity Modelling Within a Probabilistic Design Framework For Offshore Arctic Pipelines

The design of buried offshore pipelines in ice environments must consider extreme load events. Current practice for the characterization of geotechnical loads (i.e. system demand) and pipeline mechanical resistance (i.e. system capacity) has limitations due to idealizations and uncertainties associated with statistics of physical data sets, experimental techniques and engineering models used in analysis and design. Advancements in computational methods have provided improved engineering tools to analyse complex nonlinear geotechnical failure processes, load transfer and pipeline/soil interaction events and pipeline failure mechanisms. Probabilistic methods provide an objective, rational and quantitative framework to optimize design options with respect to technical, economic and environmental criteria that meet specified target safety levels.
Physiologie du sport : enfant et adolescent

La physiologie de l'exercice musculaire se definit comme etant l'etude des reponses et adaptations des differents systemes organiques induites par l'activite physique. De fait, elle s'interesse aux reponses aigues (immediates) faisant suite a un exercice isole et aux adaptations organiques chroniques (a long terme) provoquees par la repetition d'exercices. Il est classique de dire qu'enfants et adolescents ne sont pas des adultes en miniature. Leur developpement biologique est non seulement specifique, mais variable selon les individus. De meme, leurs differentes reponses physiologiques suite a une pratique reguliere de l'activite physique et sportive sont differentes selon leur croissance et leur stade de maturation refletant le passage de l'enfance a l'adolescence, puis au stade adulte. Cet ouvrage suppose que les principes elementaires de la physiologie de l'exercice musculaire soient connus. En effet, chaque chapitre est redige sous forme d'une revue generale des connaissances les plus recentes quant aux reponses physiologiques induites par l'activite physique et sportive au cours du developpement biologique.

Degree-Day Model for Vegetable Leafminer (Diptera: Agromyzidae) Phenology

The lack of data on temperature-dependent development of instars of Liriomyza sativae Blanchard is an impediment to research on biological control of this pest because parasitoids will likely interact differently with each instar. In this study, development times of eggs and instars of L. sativae were determined at constant temperatures of 20, 25, 30, and 35 ± 1°C on Phaseolus lunatus L. ‘Henderson’. Development rates of eggs and larvae increased linearly with temperature up to 35°C ( r 2 ≥ 0.95). More than 91% of the variation in development rate of first and second instars was explained by temperature, whereas temperature explained only 42% of the variation in third-instar development rate. A part of the variation in development rate of third instars may be explained by the fact that the designated end point of this stadium (emergence of third instars from leaves) occurred only during the photophase. Overall, 99.9% of larvae emerged from leaves after 95 degree-days (DD) (threshold temperature, 10°C). When the constant temperature data were used to parameterize a stochastic phenology model for L. sativae , the model predicted that 50% of the population would advance beyond the egg and first-, second-, and third-instar stages by 39.2, 67.0, 85.5, and 101.2 DD, respectively. The model predicted peak proportions of the population to be in first, second, and third stadia at 52.7, 76.1, and 93.2 DD. Pooled data from two fluctuating temperature experiments resulted in very similar estimates of timing of peak stage proportions (51.3, 74.4, and 94.1 DD, respectively). Degree-day values at peak stage proportions were used successfully to determine the temperatures required to advance members of a cohort to a particular stadium at a given time, thereby facilitating experiments examining interactions of parasitoids with each larval instar.

Phenolics contents and sensory characterisation of melting and non-melting peach

Summary There is increasing consumer dissatisfaction regarding the quality of peaches due to the rapid decay that these fruit undergo after harvest. This study aimed to determine the phenolics contents and provide sensory characterisations of four commercial melting flesh (MF) and four commercial non-melting flesh (NMF) peach cultivars. Low molecular weight phenolic compounds (LMWPC) were determined by high performance liquid chromatography coupled to a diode array detector (HPLC-DAD). A trained sensory panel with 12 members evaluated the principal quality attributes of each cultivar. Skin ground colour was different among the MF and NMF cultivars. Fifteen LMWPC were identified in peach flesh tissue. Procyanidin gallate 1, procyanidin gallate 3, procyanidin B3, and flavonoids 1, 2, and 3 were detected in all eight cultivars, while gallic acid was present only in ‘Elegant Lady’. Two main clusters were formed based on the 15 LMWPC observed, but no correlation with flesh type was observed. On the other hand, a principal components analysis (PCA) based on sensory attributes showed a clear segregation between the MF and NMF cultivars. The NMF cultivars were associated with “texture” and a low score for “visual appearance”, while the MF cultivars were associated with attributes such as “sweetness”, “juiciness”, and “flavour”. The types and amounts of LMWPC were not correlated with flesh type in both these peach cultivars (MF and NMF). LMWPC profiles were therefore more dependent on genetic background than on the specific MF or NMF trait.
Mixed histology poses a greater risk for noncurative endoscopic resection in early gastric cancers regardless of the predominant histologic types.

OBJECTIVES Clinicopathologic characteristics and treatment outcomes of mixed-histological-type (MT) early gastric cancers (EGCs) treated with endoscopic submucosal dissection (ESD) have not been sufficiently elucidated. We aimed to clarify them in comparison with pure-histological-type EGCs. METHODS We used 3022 consecutive EGCs in 2281 patients treated with ESD from our prospectively maintained database. Cases were stratified into four groups according to the final diagnosis of the resected specimen are as follows: 2780 pure differentiated-type (DT), 127 DT-predominant MT (D-MT), 87 pure undifferentiated-type (UDT), and 28 UDT-predominant MT (U-MT). Clinicopathologic characteristics and treatment outcome were compared between pure DT and D-MT, and between pure UDT and U-MT separately. Risk factors for deep submucosal invasion, lymphovascular invasion, and a final diagnosis of MT were identified using multivariate analysis. RESULTS Both D-MT (41.7 vs. 92.0%; P < 0.0001) and U-MT (35.7 vs. 75.9%; P = 0.0002) showed a significantly lower curative resection rate than their pure histologic counterparts. Multivariate analysis revealed that MT was an independent risk factor for deep submucosal (OR 6.55; 95% CI, 4.18-10.14) and lymphovascular (OR 4.74; 95% CI, 2.72-8.29) invasion. Preoperative biopsy results that did not show well-differentiated tubular adenocarcinoma (OR 28.2; 95% CI, 18.9-42.9) were an independent risk factor for a final diagnosis of MT. CONCLUSIONS MT poses a greater risk for noncurative resection regardless of the predominant histologic types, reflecting more aggressive malignant potential. Although a biopsy examination rarely shows MT, clinicians should consider the possibility of MT when a biopsy examination does not show well-differentiated tubular adenocarcinoma.
Development of Fully Flexible Tactile Pressure Sensor with Bilayer Interlaced Bumps for Robotic Grasping Applications

Flexible tactile sensors have been utilized in intelligent robotics for human-machine interaction and healthcare monitoring. The relatively low flexibility, unbalanced sensitivity and sensing range of the tactile sensors are hindering the accurate tactile information perception during robotic hand grasping of different objects. This paper developed a fully flexible tactile pressure sensor, using the flexible graphene and silver composites as the sensing element and stretchable electrodes, respectively. As for the structural design of the tactile sensor, the proposed bilayer interlaced bumps can be used to convert external pressure into the stretching of graphene composites. The fabricated tactile sensor exhibits a high sensing performance, including relatively high sensitivity (up to 3.40% kPa−1), wide sensing range (200 kPa), good dynamic response, and considerable repeatability. Then, the tactile sensor has been integrated with the robotic hand finger, and the grasping results have indicated the capability of using the tactile sensor to detect the distributed pressure during grasping applications. The grasping motions, properties of the objects can be further analyzed through the acquired tactile information in time and spatial domains, demonstrating the potential applications of the tactile sensor in intelligent robotics and human-machine interfaces.
