Coordinated constant voltage control strategies of a battery‐free medium‐voltage direct current system incorporating distributed photovoltaic generation units
Authors: Fan Yiwen , Chi Yongning , Li Yan , Fan Xiaojie , Liu Hongzhi 
Published: September 2022

AbstractTraditional distributed photovoltaic generation units (DPVGUs) with maximum power point tracking (MPPT) control strategies are generally regarded as current sources without voltage regulation capability. Due to the lack of voltage regulation capability of DPVGUs, this paper proposes two control strategies to realise the voltage regulation capability of a battery‐free medium‐voltage DC (MVDC) system incorporating DPVGUs in the off‐grid mode. A primary control strategy used on an individual DPVGU is proposed first, which is called an improved DC constant voltage control (CVC) strategy. Under this strategy, the maximum dynamic output characteristics of a photovoltaic (PV) panel and the boost capability of a DC/DC boost converter can be fully utilised to control the MVDC system bus voltage. Secondly, the sequential coordinated constant voltage control (SCCVC) strategy is then proposed on the condition that the limitation of the voltage regulation capability of an individual DPVGU is reached. Under the SCCVC strategy, according to the sequence of the voltage regulation capability of the DPVGUs from large to small, the DPVGUs take turns to operate in the improved DC CVC strategy to realise the voltage control function. Furthermore, simulations using the RTDS are conducted to verify the effectiveness of the proposed control strategies in actual applications.
Gestion d'une lésion en regard d'une articulation : illustration par une plaie en face d'un carpe
Authors: de Chaisemartin Charles 
Published: September 2022

L’atteinte des structures synoviales est fréquente en cas de plaie des membres et peut engager le pronostic sportif, voir vital du cheval. A travers ce rapport de cas, un exemple est donné de l’évaluation d’une structure synoviale.
Un hongre est référé après avoir été retrouvé avec une plaie en face dorso-latérale du carpe droit. Bien que la plaie soit en regard de l’articulation radiocarpienne droite, l’examen met en évidence une atteinte des couches plus profondes quand le membre est mis en flexion. La ponction du liquide synovial et un test de distension mettront en évidence une contamination de l’articulation médio-carpienne en communication avec la plaie. Une arthroscopie permettra finalement d’affiner le diagnostic, de laver l’articulation et de fermer la plaie.
Ce cas souligne l’importance de l’évaluation des structures touchées initialement. L’observation des tissus en position statique ne correspond pas toujours à la position des tissus lors de la chute. La confirmation d’atteinte articulaire a été réalisée grâce à la ponction de l’espace synovial. Avec le test de distension, ce geste remplit des objectifs diagnostiques et thérapeutiques. Cette manipulation peut freiner les praticiens sur le terrain. Pourtant, elles ne sont la résultante d’une infection que dans moins de 0,1 % des cas. Enfin, le comptage cellulaire ne constitue que l’un des paramètres à évaluer. La couleur, la quantité, la turbidité, la viscosité et la quantité de protéines sont également des paramètres qui rentrent en compte dans l’analyse.

Published: September 2022

Abstract
Introduction Dysphonia and lower pitch after surgery of Reinke edema are common. They are caused especially due to chronic smoking but, probably, other factors should be associated.
Objectives To evaluate the results of laryngeal microsurgery in patients with Reinke edema, following a standardized postoperative guidance protocol in our service.
Methods Retrospective study. Thirty patients (3 males; 27 females) were included, 70% between 41 and 60 years old. The parameters analyzed in the pre- and postoperative (between 4 and 6 months) of patients undergoing laryngeal microsurgery for Reinke edema were: smoking, vocal symptoms, videolaryngostroboscopy, voice therapy, perceptual and acoustic vocal evaluation, histopathological report.
Results Smoking was reported by 100% of the patients and maintained in the postoperative period by 80%. Complete improvement of symptoms in the postoperative period was reported by 43% of them, partial improvement by 40%, and maintenance by 17%.There was low adherence to voice therapy in the pre- and postsurgery.Postoperative videolaryngoscopy indicated congestion (19), atrophy and bowed vocal fold (1), subepithelial edema (2), and normal findings (8). The histological findings were subepithelial edema, enlargement of vessels, inflammation, epithelial hyperplasia, and thickening of the basement membrane. The perceptual and acoustic vocal analyzes indicated improvement of the analyzed parameters.
Conclusions The maintenance of some vocal symptoms and laryngeal alterations in videolaryngoscopy after microsurgery of Reinke edema is frequent, even in patients who follow the recommendations of vocal rest and control of gastroesophageal reflux. Vocal symptoms are attributed to changes in the laryngeal mucosa caused by chronic smoking, aggravated by the maintenance of addiction in the postoperative period.

Abstract
Introduction Acquired tracheomalacia (ATM) is characterized by a loss of structural strength of the tracheal framework, resulting in airway collapse during breathing. Near half of the patients undergoing prolonged invasive mechanical ventilation will suffer tracheal lesions. Treatment for ATM includes external splinting with rib grafts, prosthetic materials, and tracheal resection. Failure in the use of prosthetic materials has made reconsidering natural origin scaffolds and tissue engineering as a suitable alternative.
Objective To restore adequate airway patency in an ovine model with surgically-induced ATM employing a tissue-engineered extraluminal tracheal splint (TE-ETS).
Methods In the present prospective pilot study, tracheal rings were partially resected to induce airway collapse in 16 Suffolk sheep (Ovis aries). The TE-ETS was developed with autologous mesenchymal-derived chondrocytes and allogenic decellularized tracheal segments and was implanted above debilitated tracheal rings. The animals were followed-up at 8, 12, and 16 weeks and at 1-year postinsertion. Flexible tracheoscopies were performed at each stage. After sacrifice, a histopathological study of the trachea and the splint were performed.
Results The TE-ETS prevented airway collapse for 16 weeks and up to 1-year postinsertion. Tracheoscopies revealed a noncollapsing airway during inspiration. Histopathological analyses showed the organization of mesenchymal-derived chondrocytes in lacunae, the proliferation of blood vessels, and recovery of epithelial tissue subjacent to the splint. Splints without autologous cells did not prevent airway collapse.
Conclusion It is possible to treat acquired tracheomalacia with TE-ETS without further surgical removal since it undergoes physiological degradation. The present study supports the development of tissue-engineered tracheal substitutes for airway disease.

Abstract
Objectives The objectives of this study are to describe the role of dual-energy computed tomography (DECT) in evaluation of renal stones in current practice and elaborate the imaging findings that need to be reported to help surgeons make an appropriate management strategy for renal stones.
Background Nephrolithiasis is a global problem, affecting people across geographical, cultural, and economic boundaries. Renal stones can be accurately diagnosed on computed tomography.
Discussion With the development of DECT, renal stones can now be better characterized in terms of stone burden, stone composition, and stone fragility.
Conclusion These parameters are helpful to treating surgeons in not only planning an appropriate management for patient but also in predicting the success of the various procedures such as extracorporeal shock wave lithotripsy, flexible ureterorenoscopy, or percutaneous nephrolithotomy. Familiarity with recent developments will help radiologists give an apt description of renal stone to meet the requirements of treating surgeon.
When institutions matter: electoral systems and intraparty fractionalization in Western Europe
Authors: Emanuele Vincenzo , Marino Bruno , Diodati Nicola Martocchia 
Published: September 2022

AbstractThe comparative study of intraparty divisions and their determinants has been a long-debated matter, but some issues remain unresolved. First, the problem of the empirical identification of intraparty groups. Second, the lack of comparative perspective and large-N cross-country and cross-time analyses, given intraparty divisions have been studied mostly through theoretical or, at best, small-N analyses. Third, the underestimation of the potential role exerted by contextual factors because of the emphasis put almost exclusively on intraparty dynamics. To fill these gaps, the article employs a measure of visible intraparty fractionalization allowing for large-N cross-time and cross-country comparison. Moreover, by focusing on about 700 party cases in 11 Western European countries since 1965, the article shows that institutional factors, particularly electoral systems’ characteristics, impact intraparty fractionalization. Specifically, intraparty fractionalization is higher in more disproportional systems and where there are stronger incentives for personal vote.
The benefits of social interaction and proficiency for foreign language acquisition of Spanish conventional expressions
Authors: Denbaum-Restrepo Nofiya 
Published: September 2022

AbstractSeveral studies have examined the second language acquisition of English conventional expressions (CEs) in the study abroad context. However, there is a lack of studies that investigate Spanish CEs and CEs in general in the at-home context. This study examines the foreign language acquisition of Spanish CEs in the at-home context and the effect of proficiency and Spanish social interaction outside of the classroom. Three levels of learners (3rd semester, 5th semester, and graduate level) (N = 32) and a Spanish speaker comparison group (N = 10) completed an oral discourse completion task, a recognition task, and a social interaction questionnaire. Results showed that social interaction in Spanish leads to better recognition of conventional expressions and that proficiency is a significant predictor of production of these expressions. Results have pedagogical implications, including the importance for instructors to provide input of expressions related to a variety of contexts.
Molecular beam mass spectrometry measurements of vibrationally excited N2 in the effluent of an atmospheric plasma jet: a comparison with a state-to-state kinetic model

Published: September 2022

Abstract
Vibrationally excited N2 molecules are suggested to be one of the possible key species responsible for the observed synergistic effects in plasma catalysis for NH3 synthesis. To assess the impact of vibrationally excited species in plasma-catalysis, quantitative measurements near interfaces are required, which remains challenging. In this letter, we report spatially resolved measurements of vibrationally excited N2 in the effluent of an atmospheric pressure plasma jet by molecular beam mass spectrometry (MBMS). The mass spectrometry signals as a function of electron energy of the ionizer were fitted with the effective electron-impact ionization cross section of N2(v) considering the vibrational distribution function as determined by a detailed vibrational level resolved plasma kinetic calculation. The reported method presented in this letter shows the capability of MBMS to measure vibrationally excited species of N2 near interfaces when the vibrational distribution function is known or assumed and shows excellent agreement with state-to-state kinetic models of N2(v).

Abstract
There has been a lot of research on hybrid composites, but most of the research is limited to traditional composites. As a kind of thermo-responsive material, the mechanical properties of shape memory polymer composites (SMPCs) vary dramatically with temperature, so researches on the isothermal mechanical properties of hybrid SMPCs under different temperatures are necessary. This paper investigates the flexural and shape memory performances of carbon fiber (CF) and glass fiber (GF) reinforced hybrid SMPCs. After determining the lamina properties of CF and GF laminae at different temperatures, the flexural properties of hybrid SMPCs were predicted by simulation and theoretical calculations, which agreed well with the subsequent experimental results. The failure modes, dynamic thermomechanical properties, and shape memory properties of hybrid SMPCs with different fiber stacking configurations at different temperatures were then investigated. Finally, the effects of hybrid ratios on the flexural moduli of hybrid SMPCs at different temperatures were studied.
Comprehensive analysis of gene regulatory dynamics, fitness landscape, and population evolution during sexual reproduction
Authors: Okubo Kenji , Kaneko Kunihiko 
Published: September 2022

Abstract
The fitness landscape is a critical concept in biophysics, evolutionary biology, and genetics that depicts fitness in the genotype space and visualizes the relationship between genotype and fitness. However, the fitness landscape is challenging to characterize because the quantitative relationships between genotype and phenotype and their association to fitness has not been comprehensively well described. To address this challenge, we adopted gene regulatory networks to determine gene expression dynamics. We analyzed how phenotype and fitness are shaped by the genotype in two-gene networks. A two-by-two matrix provided the two-gene regulatory network in which a vector with two angle values (Θ) was introduced to characterize the genotype. Mapping from this angle vector to phenotypes allowed for the classification of steady-state expression patterns of genes into seven types. We then studied all possible fitness functions given by the Boolean output from the on/off expression of the two genes. The possible fitness landscapes were obtained as a function of the genetic parameters Θ. Finally, the evolution of the population distribution under sexual reproduction was investigated in the obtained landscape. We found that the distribution was restricted to a convex region within the landscape, resulting in the branching of population distribution, including the speciation process.

Published: September 2022

Abstract
In recent years, it is becoming inevitable to design/construct eco-friendly sustainable electronic and photonic devices to minimize the footprints of these as part of the fight against global problems like resource depletion and pollution. To this end, scientists have been researching to produce sustainable, self-powered electronic and photonic devices capable of meeting the standards of consumers along with minimal adverse effects on the environment. In this study, we fabricated and analyzed a high-performance self-powered silicon carbide ultraviolet photodetector (SiC-UVPD) through functionalizing with gold nanoparticles (Au NPs). The effect of Au NPs on the improvement of the photodetector was systematically investigated. The self-powered SiC-UVPD exhibited a very good responsitivity of 0.30 A W−1 and a detectivity of 7.0 × 1011 cm.Hz1/2.W−1 under 254 nm wavelength UV light irradiation without any external power. The photodetector also provided quick responses to incident UV light with 28 ms rise time and 88 ms fall time. To sum up, the performance of the fabricated self-powered SiC-UVPD shows that SiC-UVPDs can offer new solutions for high performance emerging sustainable energy and eco-friendly optoelectronic devices.

Abstract
We generate new spherical and time-dependent solutions of viable Horndeski gravity by
disforming a solution of the Einstein equations with scalar field source and positive cosmological
constant. They describe dynamical objects embedded in asymptotically FLRW spacetimes and contain
apparent horizons and a finite radius singularity that evolve in time in peculiar ways apparently
not encountered before in Einstein and “old” scalar-tensor gravity.

Published: September 2022

Abstract

Objective. Early diagnosis of mild traumatic brain injury (mTBI) is challenging, yet crucial for providing patients with timely treatments and minimizing the risks of developing injury-related disorders. To tackle this problem, this paper presents a framework based on measures of frequency-specified brain functional networks identifying mTBI. Approach. Cortical activity of 15 control and 15 injury Thy1-GCaMP6s mice are recorded, using widefield calcium imaging, prior to and 20 minutes after inducing injury. Power spectral distribution (PSD) of the recorded cortical activities is examined, and the frequency bands with significant difference in PSD between the injury and control groups are identified. Frequency-specified functional networks are then constructed. Employing graph theoretical analysis, various network measures from the constructed frequency-specified functional networks are extracted and used as features. Several classifiers are utilized to evaluate the performance of the computed network measures, either individually or collectively as features, to classify mTBI from control. Main results. Spectral analysis reveals the presence of two dominant frequency bands (low:

<

1

Hz) and high: [1–8] Hz) in the cortical activities recorded via calcium imaging. Comparison of the brain networks of control and injury groups shows significant reduction (p < 0.05) in global functional connectivity following injury, specially for the high frequency band network. Interestingly, graph measures of the high frequency band network provided higher classification accuracy results, compared to those computed from the low frequency band network, suggesting that mTBI network-based features are frequency dependent. Using all network measures collectively as a multi-measure feature vector and a convolutional neural networks classifier, a model for identifying mTBI is developed, offering an average classification accuracy of 97.28%. Significance. Results signifies the importance of considering frequency-specific analysis in functional networks for mTBI identification, and demonstrate the possibility of using network measures for early mTBI diagnosis.
Kinematic fitting of neutral current events in deep inelastic ep collisions.
Authors: Aggarwal Ritu , Caldwell Allen 
Published: September 2022

Abstract
In this paper we present a technique to reconstruct the
scaling variables defining ep deep inelastic scattering by
performing a kinematic fit. This reconstruction technique makes use
of the full potential of the data collected. It is based on Bayes'
Theorem and involves the use of informative priors. The kinematic
fit method has been tested using a simulated sample of ep neutral
current events at a center of mass energy of 318 GeV with
Q
2 > 400 GeV2. In addition to the scaling variables, this
method is able to estimate the energy of possible initial state
radiation (Eγ
) which otherwise goes undetected. A better
resolution than standard electron and double angle techniques in the
reconstruction of scaling variables is achieved using a kinematic
fit.
