Harmonic Modeling and Analysis of Series-Parallel Compensated IPT Systems With an Inductive Filter

In the series-parallel (S-P) compensated inductive power transfer (IPT) system for the electric vehicle charging application, an inductive filter is required after the rectifier on the secondary side to avoid the large charging current surge when the diodes conduct. This article proposes a harmonic modeling method for the S-P compensated IPT systems with an inductive filter where both the fundamental and higher order harmonics are considered. Compared to the well-known fundamental harmonic approximation (FHA) method, a more accurate description can be obtained by constructing the circuit model at different harmonics, especially in a strongly coupled case. The zero-voltage switching (ZVS) condition is derived, which shows that a larger load current will cause the power switches to lose ZVS. A larger coupling coefficient will help increase the ZVS range. The output dc voltage will drop slightly due to the high order harmonics, which is different from the FHA method where the output voltage is constant regardless of the load. Experimental results are provided to validate the effectiveness of the proposed harmonic modeling method of the S-P compensated IPT system.
An antimicrobial thiopeptide producing novel actinomycetes Streptomyces terrae sp. nov., isolated from subsurface soil of arable land

Abstract An antimicrobial producing Gram-positive, aerobic, nonmotile, and filamentous actinobacterial strain SKN60T was isolated from soil The isolate exhibited 99.3% and 99.0% identity with Streptomyces laurentii ATCC 31255T and S. roseicoloratus TRM 44457T, respectively, in 16S rRNA gene sequence analysis. However, the genome sequence displayed maximum ANI (88.45%) and AAI (85.61%) with S. roseicoloratus TRM 44457T. Similarly, the dDDH showed 33.7% identity with S. roseicoloratus TRM 44457T. It formed a cluster with S. roseicoloratus TRM 44457T and S. laurentii ATCC 31255T in phylogenomic tree. Cell wall analysis revealed the presence of diphosphatidylglycerol, phosphatidylethanolamine, and phosphatidylcholine as major polar lipids and diaminopimelic acid as diagnostic diamino acid. Major fatty acids were iso-C15:0, anteiso-C15:0, and iso-C16:0. The G+C content was found to be 72.3 mol%. Genome sequence analysis using antiSMASH database showed occurrence of a thiopeptide biosynthesis gene cluster with 94% similarity to berninamycin from S. bernensis UC5144. The mass of 1146 Da is identical with berninamycin. But subtle differences observed in leader peptide sequence of thiopeptide and berninamycin. Notably, S. bernensis is not validly reported and thus SKN60T is the only strain containing berninamycin BGC as no other phylogenetic relative had it. Additionally, strain SKN60T differed in phenotypic and genetic characteristics with all phylogenetic relatives of the genus Streptomyces. Therefore, it is proposed as a novel species with the name Streptomyces terrae sp. nov. strain SKN60T (=MTCC 13163T; = JCM 35768T).
Carvedilol Phenocopies PGC-1α Overexpression to Alleviate Oxidative Stress, Mitochondrial Dysfunction and Prevent Doxorubicin-Induced Toxicity in Human iPSC-Derived Cardiomyocytes

Doxorubicin (DOX), one of the most effective and widely used anticancer drugs, has the major limitation of cancer treatment-related cardiotoxicity (CTRTOX) in the clinic. Reactive oxygen species (ROS) generation and mitochondrial dysfunction are well-known consequences of DOX-induced injury to cardiomyocytes. This study aimed to explore the mitochondrial functional consequences and associated mechanisms of pretreatment with carvedilol, a ß-blocking agent known to exert protection against DOX toxicity. When disease modeling was performed using cultured rat cardiac muscle cells (H9c2 cells) and human iPSC-derived cardiomyocytes (iPSC-CMs), we found that prophylactic carvedilol mitigated not only the DOX-induced suppression of mitochondrial function but that the mitochondrial functional readout of carvedilol-pretreated cells mimicked the readout of cells overexpressing the major regulator of mitochondrial biogenesis, PGC-1α. Carvedilol pretreatment reduces mitochondrial oxidants, decreases cell death in both H9c2 cells and human iPSC-CM and maintains the cellular ‘redox poise’ as determined by sustained expression of the redox sensor Keap1 and prevention of DOX-induced Nrf2 nuclear translocation. These results indicate that, in addition to the already known ROS-scavenging effects, carvedilol has a hitherto unrecognized pro-reducing property against the oxidizing conditions induced by DOX treatment, the sequalae of DOX-induced mitochondrial dysfunction and compromised cell viability. The novel findings of our preclinical studies suggest future trial design of carvedilol prophylaxis, such as prescreening for redox state, might be an alternative strategy for preventing oxidative stress writ large in lieu of the current lack of clinical evidence for ROS-scavenging agents.
Toughness Enhancement of PLA-Based Filaments for Material Extrusion 3D Printing

Poly(lactic acid) (PLA) is one of the most popular biodegradable thermoplastics in the market of 3D printing filaments used in the material extrusion (ME) technique. This is because it can be printed easily at low temperatures. However, its inherent brittleness limits its use in many applications. In this work, the toughness of PLA filament was improved by blending with various types of rubbers including natural rubber (NR), acrylic core–shell rubber (CSR), and thermoplastic polyurethane (TPU) in the amount of 15% by weight. PLA/TPU filament was found to have the smoothest surface with the best shape and dimension stability, while PLA/NR filament rendered the highest tensile toughness. In term of the effect of printing temperature, the highest printing temperature in this study (210°C) provided the highest smoothness with the best shape stability and dimension accuracy. Interestingly, the tensile toughness and elongation at break of 3D printed specimens were found to be higher than those of compression-molded specimens for all filament types. This could be explained by the ability of the 3D printing technique to produce specimens that aligned in the printing direction in a fiber-like pattern.
Video Scene Detection Using Transformer Encoding Linker Network (TELNet)

This paper introduces a transformer encoding linker network (TELNet) for automatically identifying scene boundaries in videos without prior knowledge of their structure. Videos consist of sequences of semantically related shots or chapters, and recognizing scene boundaries is crucial for various video processing tasks, including video summarization. TELNet utilizes a rolling window to scan through video shots, encoding their features extracted from a fine-tuned 3D CNN model (transformer encoder). By establishing links between video shots based on these encoded features (linker), TELNet efficiently identifies scene boundaries where consecutive shots lack links. TELNet was trained on multiple video scene detection datasets and demonstrated results comparable to other state-of-the-art models in standard settings. Notably, in cross-dataset evaluations, TELNet demonstrated significantly improved results (F-score). Furthermore, TELNet’s computational complexity grows linearly with the number of shots, making it highly efficient in processing long videos.
Good Outcome With Respect to Acute Necrotizing Encephalitis in Children Associated With Post-infectious SARS-CoV-2

This case report demonstrates an excellent outcome in a child with acute necrotizing encephalitis that was likely associated with the post-infectious SARS-CoV-2. The aim of this report is to emphasize that early diagnosis and initiation of immunotherapy treatment may yield good outcome, particularly with the use of tocilizumab and high-dose methylprednisolone. Post immunotherapy, significant neurological improvement was seen through the gradual improvement of Glasgow Coma Scale (GCS) score of 6 to GCS score of 12 within three weeks and subsequently acquired almost full neurological function with minimally dependent activity of daily living (ADL) at eight weeks in the post-treatment follow-up. It is interesting to identify that the possible causative factor could be the natural infection in a vaccinated patient. This was evidenced by the persistently high SARS-CoV-2 immunoglobulin G (IgG)-Spike antibodies titre in a patient vaccinated with two doses of BNT162b2, 11 months before presentation.

Use of a novel shockwave trode results in better patient acceptance in awake canine patients treated for musculoskeletal disease

Introduction Extracorporeal shockwave therapy (ESWT) is used as a treatment option for several musculoskeletal pathologies in dogs. When performing ESWT using electrohydraulic devices, sedation is commonly recommended due to the noise and discomfort associated with the treatment. The aim of this study was to compare the tolerance of ESWT delivered by a standard or novel trode in awake canine patients with musculoskeletal disease. Materials and methods This was a prospective, blinded clinical trial in which dogs with musculoskeletal disease received awake treatment with ESWT with a gradually increasing energy protocol using both standard and novel trodes with an electrohydraulic generator in a randomized fashion. Noise reactivity and tolerance to treatment as measured in number of shocks and energy level achieved were recorded. Results Forty client-owned dogs with pathology affecting the hips, stifles, elbows, or shoulders were enrolled. Thirty-three dogs completed all three treatment sessions, three dogs completed two sessions, and four dogs completed one session. There was evidence of improved patient tolerability with the novel trode, based on an increased average number of shocks delivered (n ± SD = 848 ± 334 for novel trode; n ± SD = 767 ± 358 for standard trode; p = 0.0384) and higher average treatment energy level achieved (E ± SD = 6.5 ± 2.5 for novel trode; E ± SD = 5.3 ± 2.8 for standard trode; p = < 0.001). Decreased noise reactivity was found to be positively correlated with tolerability of shockwave treatment (energy level: p = 0.0168; number of shocks: p = 0.0097). Discussion Administration of electrohydraulic ESWT is feasible in select awake patients using a gradually increasing energy protocol, and the tested novel shockwave trode is better tolerated than the standard trode. Further studies are required to determine the efficacy of the novel trode, and if gradually increasing energy protocols are clinically equivalent to current standard protocols that employ a consistent energy level.
High Performance Inversion-Mode In0.53Ga0.47As FinFETs for Logic and RF Applications

An inversion-mode In0.53Ga0. 47As FinFET exhibiting a transition frequency (fT) of 271 GHz and a maximum oscillation frequency (fmax) of 78 GHz at Vds = 0.5 V is reported in this work. Simultaneously, the transconductance (gm) of 2056 (μS/μm) and drain induced barrier lowering (DIBL) of 121 (mV/V) obtained were also exhibited. Moreover, a subthreshold swing (SS) of 86 and 97 (mV/dec) was obtained at Vds = 0.05 and 0.5 V, respectively. These exceptional properties are the result of employing N2 remote plasma treatment, enhancing the quality of high-k/III-V interface and carrier mobility. The fin structure contributes to good suppression of short channel effects (SCEs), and the superior transfer characteristics are due to the improved gate controllability. We also extracted an effective electron velocity (νeff) of 2.18 × 107 (cm/s) by delay time analysis, providing a probable explanation for the obtained fT performance. This work explicitly exhibits the potential of high-performance inversion-mode InGaAs FinFETs, positioning them as promising candidates for future high-frequency system applications.
Temporary Property Tax Relief and Residential Home Sales

This paper tests whether temporary property tax relief influences sales of eligible properties. We examine the short-run impact of a new five-year property tax credit made available to long-tenured senior homeowners in Maryland using property-level assessment and transaction data. We find that the temporary credit resulted in a statistically insignificant and economically modest decline in sales of eligible properties. We also find no change in non-arm’s-length sales of eligible properties, which include foreclosures. The results suggest temporary property tax relief does not induce short-term lock-in effects among eligible homeowners.
Grands pélagiques et Dispositifs de Concentration de Poissons (DCP) en Martinique (Antilles françaises)

Les ressources recifales et cotieres du plateau insulaire de la Martinique subissent une pression anthropique croissante et ne sont plus en mesure d'assurer un revenu suffisant aux pecheurs professionnels. La presente etude a pour objectif d'accompagner le redeploiement de l'activite de la flottille martiniquaise de proximite vers l'exploitation des ressources en grands poissons pelagiques a l'aide de dispositifs de concentration de poissons (DCP), sans imposer un changement d'echelle des unites d'exploitation. Les travaux sont developpes selon deux axes complementaires (i) l'amelioration technologique des DCP, (ii) une meilleure connaissance de la biologie des grands poissons pelagiques exploitables dans la zone d'activite de la flottille. La modelisation du comportement des DCP sous l'action des courants, completee par un suivi technologique en mer, permet de faire progresser la conception des dispositifs ancres et d'accroitre leur duree de vie. Les peches experimentales ont revele la presence de ressources accessibles pour les petites unites de peche, durant de longues periodes au cours de l'annee: l'espadon (Xiphias gladius), le thon noir adulte (Thunnus atlanticus), l'albacore (Thunnus albacares). Elles ont permis de mieux definir les moyens de capture a mettre en œuvre pour leur exploitation. En complement des resultats obtenus sur la technologie des DCP et sur la biologie des especes agregees, cette etude permet d'identifier des priorites de recherche dans les differents domaines abordes. Ces priorites ont ete discutees au niveau international dans le cadre du colloque Peche thoniere et DCP organise en Martinique a l'issue du programme. Parmi ces priorites, l'etude du comportement agregatif des principales especes d'interet halieutique permettrait une meilleure evaluation de l'impact biologique des DCP (piege ecologique).
¿Cómo influye la falta de sueño sobre la conducta adictiva?

En su Tractatus Theológico-Politicus, Baruch Spinoza escribió que “es una ley universal de la naturaleza humana que nadie rechaza lo que considera bueno excepto por la esperanza de un bien mayor o el miedo a una gran pérdida, y que nadie soporta ningún mal excepto para evitar un mal mayor u obtener un gran bien”. En otras palabras, para Spinoza existían dos fuerzas fundamentales que dirigían la conducta humana: la búsqueda de recompensas y la evasión del castigo. En las neurociencias, una recompensa puede definirse como aquel estímulo que se traduce en sentimiento de placer, excitación y gozo; es el componente principal del aprendizaje basado en incentivos y la realización de conductas dirigidas y consumatorias. Históricamente, las recompensas le han permitido al humano sobrevivir al conservar aquellas conductas que facilitan la obtención de alimento, agua, compañía, sexo y descendencia. No obstante, al mismo tiempo han influido en el desarrollo de conductas nocivas como la compulsión y el abuso de sustancias. Una de las principales metas de la investigación neurobiológica es entender los cambios a nivel molecular, celular y de circuitos que medían la transición del uso ocasional y controlado de dichas sustancias a la pérdida de control en el consumo y la adicción. En este trabajo se explicarán las bases neurobiológicas que subyacen en la transición entre en el placer y la compulsión. Posteriormente, se relacionará la influencia de la reducción de horas de sueño como factor de riesgo en el aumento en el consumo de drogas y alimentos palatables así como las bases biológicas de esta interacción.
Investigations on the temperature-dependent tribological behaviour of spark plasma sintered CNT-304 SS self-lubricating nanocomposites

Herein, we report the tribological behaviour of CNT-304 stainless steel composites at room (28°C) and high temperatures (200°C). Nanocomposites of various CNT concentrations, namely 0.2, 0.5, 1.0, 2.0, 3.0, and 4.0 wt%, were prepared. A significant amount of grain refinement resulted in an increase in CNT loading. A tribological study was carried out at 28°C and 200°C. Wear resistance was found to enhance with an increase in CNT concentration at both temperatures. However, a slightly higher wear rate was observed at 200°C for the samples with CNT content < 3 wt% than their corresponding low-temperature values. About 86%, 91% drop-in wear rate was seen in 2.0 wt% CNT-304 SS, and 4.0 wt% CNT-304SS, respectively, as compared to pure SS at 28°C, which is 54% and 88% decrease at 200°C and is very promising. The decrease in wear volume with CNT content at both temperatures can be ascribed to the self-lubricating and reinforcing nature of CNTs in the metal matrix composites. Severe abrasive wear in the pristine SS samples was slowly changed to mild abrasive and lubricated wear in composites. A systematic study on the tribological behaviour of CNT-SS composites can shed light on the benefits and detriments of using them for various applications. Highlights Incorporation of CNTs into 304 SS matrix caused grain refinement. Wear rate decreased with CNT content and 4.0 wt% CNT-SS showed minimum wear rate while pristine gave the maximum at both 28°C and 200°C. About 86% and 54% decrease in wear rate were observed for 2.0 wt% CNT-304 SS at 28°C and 200°C respectively as compared to the pristine 304 SS sample. Wear rate at 200°C was slightly more than that of room temperature (28°C) for CNT content < 3 wt%. The 3.0 wt% CNT-304 SS and 4.0 wt% CNT-304 SS showed nearly the same wear rate at both ambient and 200°C test.

SSRN: A Nonlocal Sparse Attention and Multiscale Fusion Super Resolution Network for Spacecraft ISAR Image

Inverse synthetic aperture radar (ISAR) is a popular space object detection method. However, due to the complex flight conditions of spacecraft and limited observation time, the resolution of spacecraft ISAR images is reduced. Although there are many methods of ISAR image super resolution, but none of them aim at spacecraft. To this end, in this letter, we analyze the characteristics of spacecraft ISAR images, and first propose an approach space super resolution network (SSRN), suitable for spacecraft ISAR images. Specially, our approach is designed to utilize the repetitive structures commonly observed in spacecraft ISAR images. So we introduce nonlocal sparse attention (NLSA) to capture the long-distance self-similarity in the spacecraft ISAR image. Spherical locality sensitive hashing (SLSH) is used to construct multiple attention buckets, and the query feature and features in the same and adjacent buckets are used for attention operations. To effectively extract multiscale features and contrast features from spacecraft ISAR image, we design the Residual Atrous Spatial Pyramid Pooling block (ResASPPblock), connect a number of atrous convolution layers with different dilation rates, and add the skip connection. The experiment on the real ISAR image of a certain type spacecraft proves the effectiveness of our approach, and the performance of our approach is higher than the popular ISAR super resolution method. Overall, our approach provides a promising solution for improving the resolution of spacecraft ISAR images.
Hormonal Regulation in Animals

Hormonal regulation is an essential biochemical process for the life of the animal organism. This document is a bibliographic review article whose objective was to analyze hormonal regulation in animals, taking as a reference cell as a morphological, physiological, genetic and reproductive entity of any living being. For this, an exhaustive documentary investigation was carried out regarding the subject matter, where the most suitable articles were chosen from scientific journals indexed in various international repositories (Scielo, Latindex, Elseiver). The body of the article consists of two fundamental sections which are: hormonal regulation at the cellular level and the importance of hormonal concentration. The analysis of the documents shows that hormones exert a local and systemic effect at the organic level through biochemical signaling in the H-R complex, which has a decisive impact on cell physiology. According to the results of the review, it is concluded that hormonal regulation allows channeling metabolic or physiological mechanisms at the cellular and tissue level, through feedbacks of increasing and decreasing plasma concentrations at the blood level, and through the HR Complex for homeostatic maintenance necessary for life.
The Contribution of TRPA1 to Corneal Thermosensitivity and Blink Regulation in Young and Aged Mice

The role of TRPA1 in the thermosensitivity of the corneal cold thermoreceptor nerve endings was studied in young and aged mice. The contribution of the TRPA1-dependent activity to basal tearing and thermally-evoked blink was also explored. The corneal cold thermoreceptors’ activity was recorded extracellularly in young (5-month-old) and aged (18-month-old) C57BL/6WT (WT) and TRPA1−/− knockout (TRPA1-KO) mice at basal temperature (34 °C) and during cooling (15 °C) and heating (45 °C) ramps. The blink response to cold and heat stimulation of the ocular surface and the basal tearing rate were also measured in young animals using orbicularis oculi muscle electromyography (OOemg) and phenol red threads, respectively. The background activity at 34 °C and the cooling- and heating-evoked responses of the cold thermoreceptors were similar in WT and TRPA1-KO animals, no matter the age. Similar to the aged WT mice, in the young and aged TRPA1-KO mice, most of the cold thermoreceptors presented low frequency background activity, a low cooling threshold, and a sluggish response to heating. The amplitude and duration of the OOemg signals correlated with the magnitude of the induced thermal change in the WT but not in the TRPA1-KO mice. The basal tearing was similar in the TRPA1-KO and WT mice. The electrophysiological data suggest that the TRPA1-dependent nerve activity, which declines with age, contributes to detecting the warming of the ocular surface and also to integrating the thermally-evoked reflex blink.
