Published: January 2023

This study proposed to investigate the generation mechanism of raisins-derived volatile compounds during unsaturated fatty acids oxidation (UFAO) using a mixture of fatty acids (FAs) and four individual FA at different time intervals (0, 4, 8, 12, 16, and 20 days; 60 °C). During the sun-drying of ‘Thompson Seedless’ grapes (Vitis vinifera L.), a total of 39 UFAO-derived volatiles were characterized by the GC-MS. Firstly a pH value of 4.2 was optimized to proceed with a raisin drying-like UFAO model reaction. Afterward, GC-MS quantification revealed 45 UFAO-derived volatiles, and the maximum numbers of compounds were identified in the interaction of all FAs (39) following linoleic acid (29), erucic acid (27), oleic acid (25), and linolenic acid (27). Pentanoic acid, (E,E)-2,4-octadienal, and n-decanoic acid were only quantified in all FAs, linoleic acid, and erucic acid, respectively. This study showed that all FAs reactions were found to be responsible for the generation of a greater number of UFAO-derived volatiles with higher concentrations.

A total of 24,000 healthy 1-day-old Arbor Acres broilers with similar initial weights were used in this study and fed a basal diet supplemented with 0, 400 and 800 mg/kg isoleucine (Ile), denoted CON, ILE400 and ILE800, respectively. Results revealed that the final body weight, average daily weight gain, and eviscerated carcass rate, of broiler chickens in the ILE400 group were significantly higher than in other groups (p < 0.05). In addition, the ILE400 and ILE800 groups had a lower feed conversion rate and a higher survival rate and breast muscle rate (p < 0.05), while the abdominal fat rate was significantly lower than the CON group (p < 0.05). There were significantly lower serum concentrations of UREA, glucose (GLU) and total cholesterol (TCHO) in the ILE400 and ILE800 groups than in the CON group (p < 0.05); glutathione peroxidase (GSH-Px) activity was significantly higher in the ILE400 group than in the other groups, and tumor necrosis factor-alpha (TNF-α) concentration was considerably lower than in other groups (p < 0.05). Moreover, interleukin (IL)-10 concentration in the ILE800 group was significantly higher than in the other groups (p < 0.05). The ILE400 group significantly down-regulated the mRNA expressions of fatty-acid synthase (FASN) and solid alcohol regulatory element binding protein 1c (SREBP1c), and significantly up-regulated the mRNA expressions of adipose triglyceride lipase (ATGL), hormone-sensitive lipase (HSL), lipoprotein lipase (LPL) and sirtuin1 (Sirt1) (p < 0.05). The ILE400 group had significantly higher intestinal villus height than the CON and ILE800 groups, while the ILE800 group had significantly lower intestinal villus height/crypt depth (p < 0.05). Furthermore, high-throughput sequencing showed that the Shannon index, and Verrucomicrobiota, Colidextribacter and Bacteroides abundances were significantly higher in the ILE400 group than in the CON group (p < 0.05). Interestingly, the ILE800 group reduced the Simpson index, phylum Firmicutes and Bacteroidota abundances (including genera Colidextribacter, Butyricicoccus, [Ruminococcus]_torques_group, Bacteroides, Alistipes, Barnesiella and Butyricimonas), and increased Proteobacteria and Cyanobacteria (including genera Dyella, Devosia, unidentified_Chloroplast and Hyphomicrobium) (p < 0.05). Overall, our study showed that adding 400 mg/kg Ile to the diet (diets total Ile levels at 1.01%, 0.90% and 0.87% during the starter, grower and finisher phases, respectively) increased production performance and improved the health status in broiler chickens.

Published: January 2023

Abstract
Benefitted from progress on the large-diameter Ga2O3 wafers and Ga2O3 processing techniques, the Ga2O3 power device technology has witnessed fast advances toward power electronics applications. Recently, reports on large-area (ampere-class) Ga2O3 power devices have emerged globally, and the scope of these works have gone well beyond the bare-die device demonstration into the device packaging, circuit testing, and ruggedness evaluation. These results have placed Ga2O3 in a unique position as the only ultra-wide bandgap semiconductor reaching these indispensable milestones for power device development. This paper presents a timely review on the state-of-the-art of the ampere-class Ga2O3 power devices (current up to >100 A and voltage up to >2000 V), including their static electrical performance, switching characteristics, packaging and thermal management, and the overcurrent/overvoltage ruggedness and reliability. Exciting research opportunities and critical technological gaps are also discussed.

Published: January 2023

Abstract
In this work, the effect of high-energy proton irradiation on the radiofrequency (RF) properties of silicon-on-insulator (SOI) substrates is investigated. The localized backside etching (LBE) structure is introduced for RF properties improvement and proton irradiation hardening. It is observed that after the 50 MeV proton irradiation with a fluence of 1 × 1012 p cm−2, the attenuation, crosstalk, and relative permittivity significantly decrease for conventional SOI substrates. In contrast, LBE substrates are less sensitive to proton irradiation and simultaneously exhibit better RF performance. The enhancement of the LBE structure on irradiation tolerance is qualitatively characterized by the equivalent circuit model parameter extraction.

Published: January 2023

Abstract
This letter introduces the collinear double-pulse generation method of the electro-optical Q-switched Nd:YAG laser and the rate equations describing its pulse formation dynamics. The two pulses share the same resonator and thus have a natural and highly coaxial characteristic. The effect of the voltage applied on the electro-optic crystal on the pulse energy and temporal waveform was studied. The time interval of the double-pulse laser can be tuned from 80 ns to 10 μs, thus satisfying the needs of a general double-pulse laser. This method is ideal for obtaining a collinear double-pulse laser and can be extended to other lasers.

Published: January 2023

Este artigo visa apresentar uma reflexão sobre planos de texto de aulas teóricas remotas, com foco na sequência dialogal, cujas perguntas propiciam a tão necessária interação para o aprendizado em meios digitais. O aporte teórico que embasa a discussão é formado pelos pressupostos da Linguística Textual, em sua abordagem da Análise Textual dos Discursos (ADAM, 2011, 2019; MARQUESI, 2013, 2017, 2018, 2019). A análise de duas aulas destinadas, respectivamente, a um curso de Direito e a um curso de Letras, evidencia resultados que confirmam planos de texto conduzidos por sequências textuais dialogais, com perguntas que revelam diferentes funções, como: contextualizar, motivar, tematizar, justificar, inserir com clareza objetivos, definir, conceituar, fundamentar e promover a reflexão. As conclusões apontam para planos de texto em que o autor da aula, o professor, na busca de cumprir sua intenção comunicativa, faz combinações de perguntas que lhe permitam expandir o conteúdo da aula, trazendo vozes de outros autores, conduzidas por sua voz. Essas conclusões corroboram interfaces possíveis com as metodologias ativas (BACICH, MORAN, 2017; MARQUESI, AGUIAR, 2021; MARQUESI, SILVEIRA, 2015), cujos princípios se centram na aprendizagem interativa, autônoma e significativa.

Published: January 2023

Das Einlippentiefbohren zeichnet sich durch hohe Oberflächengüte und Druckeigenspannungen in der Bohrungswand aus. Diese Eigenschaften hängen wesentlich von den thermomechanischen Bedingungen im Bearbeitungsprozess ab. Die geforderten Randzoneneigenschaften lassen sich durch Prozessregelung einstellen, wenn die thermomechanischen Bedingungen im optimalen Bereich gehalten werden. In diesem Beitrag wird eine Methode zur Regelung der Vorschubkraft vorgestellt. Die Vorgehensweise zur Ableitung der Übertragungsfunktion sowie die verwendete Hardware und die Schnittstellen werden beschrieben.

Single-lip deep-hole drilling is characterized by high surface quality and compressive residual stress in the subsurface of the drill hole. These properties depend significantly on the thermomechanical conditions in the machining process. The desired subsurface properties can be adjusted in-process via closed loop control by maintaining the thermomechanical conditions in the optimum range. This paper presents a method to control the feed force, including the procedure for deriving the transfer function and the employed hardware and interfaces.

Das in der Informationstechnik bewährte Prinzip der Virtualisierung erlaubt die parallele Nutzung mehrerer Betriebssysteme auf derselben Hardware. Zusätzliche Anforderungen in der Steuerungstechnik an Sicherheit, Verfügbarkeit und zeitliche Determiniertheit erschweren den Einsatz dieses Prinzips jedoch erheblich. Ein Konzept zur Virtualisierung und Konsolidierung industrieller Steuerungen soll die Adaption erleichtern und zur Steigerung der Wirtschaftlichkeit beitragen.

The principle of virtualization, which has proven itself in information technology, enables the parallel use of several operating systems on the same hardware. However, additional requirements in control technology in terms of security, availability and time determinism make the use of this principle significantly more difficult. A concept for virtualization and consolidation of industrial control systems is intended to facilitate adaptation and contribute to increasing economic efficiency.

High-resolution Radio Study of the Dragonfly Pulsar Wind Nebula Powered by PSR J2021+3651
Authors: Jin Ruolan , Ng C.-Y. , Roberts Mallory S. E. , Li Kwan-Lok 
Published: January 2023

Abstract
The Dragonfly Nebula (G75.2+0.1) powered by the young pulsar J2021+3651 is a rare pulsar wind nebula (PWN) that shows double tori and polar jets enclosed by a bow-shock structure in X-rays. We present new radio observations of this source taken with the Very Large Array at 6 GHz. The radio PWN has an overall size about two times as large as the X-ray counterpart, consisting of a bright main-body region in the southwest, a narrow and fainter bridge region in the northeast, and a dark gap in between. The nebula shows a radio spectrum much softer than that of a typical PWN. This could be resulting from compression by the ram pressure as the system travels mildly supersonically in the interstellar medium. Our polarization maps reveal a highly ordered and complex B-field structure. This can be explained by a toroidal field distorted by the pulsar motion.
Application of Convolutional Neural Networks to Predict Magnetic Fields’ Directions in Turbulent Clouds
Authors: Xu Duo , Law Chi-Yan , Tan Jonathan C. 
Published: January 2023

Abstract
We adopt the deep learning method casi-3d (convolutional approach to structure identification-3D) to infer the orientation of magnetic fields in sub-/trans-Alfvénic turbulent clouds from molecular line emission. We carry out magnetohydrodynamic simulations with different magnetic field strengths and use these to generate synthetic observations. We apply the 3D radiation transfer code radmc-3d to model 12CO and 13CO (J = 1−0) line emission from the simulated clouds and then train a casi-3d model on these line emission data cubes to predict magnetic field morphology at the pixel level. The trained casi-3d model is able to infer magnetic field directions with a low error (≲10° for sub-Alfvénic samples and ≲30° for trans-Alfvénic samples). We further test the performance of casi-3d on a real sub-/trans- Alfvénic region in Taurus. The casi-3d prediction is consistent with the magnetic field direction inferred from Planck dust polarization measurements. We use our developed methods to produce a new magnetic field map of Taurus that has a three times higher angular resolution than the Planck map.

Published: January 2023

Abstract
The youngest Galactic supernova remnant G1.9+0.3 shows a discrete feature between its radio and X-ray morphologies. The observed radio morphology features a single maximum in the north, while the X-ray observation shows two opposite “ears” on the east and west sides. Using 3D magnetohydrodynamical simulations, we investigate the formation of the discrete feature of the remnant. We have tested different parameters for better simulation and reproduced similar discrete features under an environment with a density gradient and an environment with clump, which provides a possible explanation of the observation.
Ce que disent les interventions des enseignants sur les copies des élèves de la place de la textualité et du genre dans les productions écrites
Authors: Moysan Arnaud , Vinel Élise , Delarue-Breton Catherine , Bautier Élisabeth 
Published: January 2023

L’analyse comparée des traces laissées sur des copies d’élèves du primaire et du secondaire par des enseignants a permis d’illustrer plusieurs pratiques : ce qui est commun et ce qui ne l’est pas dans leurs pratiques, quels que soient les niveaux scolaires et les contextes qui révèle des profils de correcteurs, l’influence du niveau du cursus scolaire, et celle des consignes d’écriture. Elle met également au jour la faible place accordée aux dimensions du genre et de la textualité. Cette faible place permet d’interroger la fonction des situations de production écrite scolaire dans le processus d’apprentissage de l’écrit, au-delà de celui de l’apprentissage de l’orthographe.
Les implications éthiques de l’accompagnement doctoral
Authors: Charmillot Maryvonne 
Published: January 2023

« Etre avec et aller vers », telle est la définition minimale du verbe accompagner. Cette perspective fait de l’accompagnement une relation particulière qui repose sur la valeur symbolique du partage (Paul, 2009). Parler d’accompagnement doctoral marque donc un positionnement conceptuel fort. Quelles sont les implications éthiques d’une telle approche et comment les identifier? Cette contribution aborde cette question à partir d’une entrée épistémologique. L’hypothèse suggérée est que malgré les chartes éthiques du doctorat qui définissent les contours de l’encadrement ou plus largement de la formation doctorale et malgré la liberté académique déterminée comme principe général de la recherche universitaire, demeure un point aveugle lié aux questionnements épistémologiques. Les doctorantes et les doctorants sont confrontés à des lacunes de significations et peuvent se sentir seuls, isolés, voire en détresse. Cette contribution propose d’actualiser les implications éthiques de l’accompagnement doctoral en reconnaissant la dimension politique des savoirs, en remettant au centre la responsabilité des chercheurs et des chercheuses, en favorisant l’engagement et en valorisant la dimension biographique dans la construction des connaissances. Ces implications sont illustrées par des exemples d’actes de recherche insolents en réponse à certaines injonctions positivistes qui mettent les doctorantes et les doctorants en difficulté.
Leukotrienes in Innate Immunity: Still Underappreciated after All These Years?
Authors: Serezani C Henrique , Divangahi Maziar , Peters-Golden Marc 
Published: January 2023

Abstract
Leukotrienes (LTs) are lipid mediators derived from the 5-lipoxygenase pathway of arachidonate metabolism. Though best known for their role in asthma, they have broad actions that touch on virtually every aspect of mammalian biology. In a Brief Review published in the journal in 2005, we presented the existing evidence supporting a role for LTs in host defense. In this updated Brief Review, we focus on selected advances since then. We detail new insights into mechanisms and regulation of LT biosynthesis; the protective roles of LTs in the host response to diverse classes of pathogens, with an emphasis on viruses, including SARS-CoV-2; the phagocyte signal transduction mechanisms by which LTs exert their antimicrobial actions; the capacity for overexuberant LT production to promote tissue damage; and roles of LTs in the noninfectious immune-relevant conditions neuroinflammation and cancer.
Effect of photodynamic therapy as an adjunctive to mechanical debridement on the nonsurgical treatment of peri-implant mucositis: A randomized controlled clinical trial
Authors: Pourabbas Reza , Khorramdel Azin , Sadighi Mehrnoosh , Kashefimehr Atabak , Mousavi Seyed Amin 
Published: January 2023

Background:
The use of photodynamic therapy (PDT) has been evaluated as an adjunctive technique for bacterial decontamination of implants with peri-implantitis. Given the controversies over the efficacy of the application of PDT to treat peri-implant diseases, the present clinical study aimed to evaluate the posttherapeutic clinical parameters and cytokine levels in peri-implant crevicular fluid in patients with peri-implant mucosal inflammation, receiving mechanical debridement (MD) alone or in association with PDT.

Materials and Methods:
In this double-blinded randomized clinical trial, 52 patients with peri-implant mucosal inflammation were selected and they were randomly assigned to 2 treatment groups: a MD group and an MD + PDT group using an 805 nm laser and indocyanine green (ICG). Although the decrease in bleeding on probing was the primary outcome, pocket depth, PUS, pain on probing, clinical attachment level, gingival recession, tumor necrosis factor-α, interleukin (IL)-1β, IL-6 and matrix metalloproteinase-8 were also evaluated at baseline, 2-week, and 3-month postintervention. Repeated measure analysis of variance was used to analyze inter-group differences and a P ≤ 0.05 was considered for significant differences between tested parameters.

Results:
Statistically significant improvements (P < 0.001) were detected for all variables after comparison of baseline data with those collected at each time interval of the study. Nevertheless, the inter-group comparisons of these variables between the baseline, 2-week, and 3-month intervals did not reveal any significant decrease in sites treated with either MD alone or MD + PDT.

Conclusion:
The application of PDT using 805-nm laser and ICG as an adjunct therapy to MD did not provide any additional improvements in the clinical or biologic parameters of peri-implant mucosal inflammation.
