Hybrid finite‐time fault‐tolerant consensus control of non‐linear fractional order multi‐agent systems based on fault detection and estimation
Authors: Nazifi Mahmood , Pourgholi Mahdi
Published: February 2024

This paper addresses the problem of achieving finite‐time fault‐tolerant consensus control for a class of non‐linear fractional‐order multi‐agent systems (NFO‐MAS) using finite‐time fault detection and estimation, as well as a finite‐time state observer. To achieve this, a specific lemma is utilized to rewrite the high‐order model of NFO‐MAS as a lower‐order NFO unique system. By employing new identification rules and introducing a fault estimation method, both the state variables and faults of the agents are estimated within a finite time. Subsequently, a finite‐time sliding mode control law is designed based on the estimated fault and the state variables obtained from the proposed finite‐time observer to achieve consensus within a finite time for the fractional‐order non‐linear MAS. The stability of the fault estimation, state observer, and consensus controller is proven using the finite‐time Lyapunov theory. The effectiveness of the proposed approach is demonstrated through numerical simulations.

Optimal resource allocation strategy for integrated sensing and communication cellular network with multiple user demands
Authors: Zhu Jia , Xie Yanxi , Jing Xiaojun , Mu Junsheng
Published: February 2024

Future communication networks are widely considered to be able to provide both high‐speed communication service and reliable sensing service. Integrated sensing and communication (ISAC) is considered to be the key technology to realize this vision. Appropriate resource allocation strategy is essential for ensuring the quality of both communication and sensing services in terms of ISAC. Existing ISAC‐based resource allocation schemes mainly focus on the coexistence of sensing and communication. However, in multi‐user ISAC networks, the services required by users are diverse, including sensing‐only, communication‐only and dual‐function cases. To this end, a resource allocation strategy is proposed based on user quality of service (QoS). Specifically, the sum rate of cellular network is maximized via optimizing spectrum resource selection and transmit power, while satisfying the sensing QoS. The optimal solution to the entire problem is achieved by first demonstrating that the communication rate in this paper is a monotonically increasing function of sensing power, which allows to obtain the optimal power allocation scheme. Subsequently, a matching method is employed to obtain the optimal spectrum sharing scheme. Numerical results validate the effectiveness of the proposed algorithm and also unveil a flexible trade‐off in ISAC systems over the benchmark scheme.
Reinforcement learning based two‐timescale energy management for energy hub
Authors: Chen Jinfan , Mao Chengxiong , Sha Guanglin , Sheng Wanxing , Fan Hua , Wang Dan , Qiu Shushan , Wu Yunzhao , Zhang Yao
Published: February 2024

Maintaining energy balance and economical operation is significant for energy hub (EH) which serves as the central component. Implementing real‐time regulation for heating and cooling equipment within the EH is challenging due to their slow response time in response to the stochastic fluctuation in renewable energy sources and demands while the opposite is true for electric energy storage equipment (EST), a conventional single timescale energy management strategy is no longer sufficient to take into account the operating characteristics of all equipment. With this motivation, this study proposes a deep reinforcement learning based two‐timescale energy management strategy for EH, which controls heating & cooling equipment on a long timescale of 1 h, and EST on a short timescale of 15 min. The actions of the EST are modelled as discrete to reduce the action spaces, and the discrete‐continuous hybrid action sequential TD3 model is proposed to address the problem of handling both discrete and continuous actions in long timescale policy. A joint training approach based on the centralized training framework is proposed to learn multiple levels of policies in parallel. The case studies demonstrate that the proposed strategy reduces the economic cost and carbon emissions by 1%, and 0.5% compared to the single time‐scale strategy respectively.
Fostering team dynamics in university sport science student: a low-constraint social identity intervention
Authors: Pellet Julien , Gabarrot Fabrice , Laurin Raphaël , Campo Mickaël
Published: February 2024

Traditionally, improving group dynamic has relied on cohesion and team building (TB) interventions. However, the time-intensive nature of TB interventions poses challenges for their implementation and effectiveness. Acknowledging the significance of the Social Identity Approach (SIA) in shaping group dynamic, this study aims to propose an enlightened TB intervention tailored for task-oriented groups. A total of 741 sports science students (Mage = 19.65; SD = 1.43; female = 187) participated in a 45-minutes intervention, based on an experimental scenario involving inter-group competition, forming 19 teams with stakes for the winners and losers. The identity group underwent a three-step intervention, including defining team boundaries, discussing team desirability and values, and creating a visual team identity symbol. The control group received a theoretical course on social identity theories. Results demonstrated a significant improvement in group belonging, ingroup ties, and cognitive centrality compared to the control group. The findings support the interest of a social identity approach for teams with demanding schedules to initiate preliminary work targeting optimal Group dynamic.
Multimodale Therapie bei pudendaler Varikose

Published: February 2024

Die pudendale Varikose wird nahezu regelhaft durch pathologischen Reflux aus dem kleinen Becken gespeist. Daher muss bei der Behandlung von Patientinnen mit pudendaler Varikose stets abgewogen werden, ob zusätzlich zur Sanierung der sichtbaren Varizen auch ein Verschluss der vorgeschalteten Refluxquelle angestrebt werden soll. Für diese Fragestellung haben wir aus unserem Krankengut einen Algorithmus entwickelt, der zur Entscheidungsfindung herangezogen werden kann. Anhand eines Fallbeispiels soll unser multimodales Konzept bei der Behandlung einer pudendalen Varikose exemplarisch dargestellt werden.

Steuerung von Patient*innen aus Notaufnahmen in die
vertragsärztliche Versorgung: Eine Machbarkeitsstudie
Authors: Koech Lea , Ströhl Sarah , Lauerer Michael , Oslislo Sarah , Bayeff-Filloff Michael , Thoß Reno , Nagel Eckhard , Carnarius Sebastian , Stillfried Dominik
Published: February 2024

Hintergrund § 120 Abs. 3b SGB V beauftragt den Gemeinsamen
Bundesausschuss (G-BA), Vorgaben zur Ersteinschätzung von
Patient*innen, die selbständig eine Notaufnahme aufsuchen sowie
zur Weiterleitung vertragsärztlich behandelbarer Patient*innen
in die ambulante Versorgung zu definieren. Ein entsprechendes Steuerungskonzept
wurde am RoMed Klinikum Rosenheim in einer Machbarkeitsstudie
geprüft.

Material und Methoden Im Studienzeitraum schätzten
Fachkräfte des Klinikums selbsteinweisende Patient*innen mit dem
Manchester Triage System (MTS) ein. Patient*innen der Kategorien
Grün und Blau, die keine Ressourcen der Zentralen Notaufnahme (ZNA)
benötigten, wurden zudem durch Fachkräfte der
Kassenärztlichen Vereinigung Bayerns mittels Strukturierter
medizinischer Ersteinschätzung in Deutschland (SmED)
eingeschätzt. Bei einer vertragsärztlichen Empfehlung erfolgte
eine Weiterleitung in die Bereitschaftspraxis oder nach hausärztlicher
Videokonsultation in Arztpraxen. Für die Evaluation wurde die Steuerung
quantitativ nachvollzogen und semistrukturierte qualitative Interviews mit
beteiligten Berufsgruppen durchgeführt und ausgewertet.

Ergebnisse1091 Selbsteinweisende wurden eingeschlossen. Eine direkte
Steuerung in die ZNA erfolgte in 525 Fällen, 13 Patient*innen
lehnten eine Teilnahme ab. Auf Grundlage des SmED-Ergebnisses wurden 24 weitere
Patient*innen in die ZNA, 514 in die Bereitschaftspraxis, 23 zur
Videokonsultation gesteuert und fünf verließen die ZNA. Nach der
Videokonsultation wurden acht Patient*innen in eine Arztpraxis
vermittelt, zehn abschließend beraten und fünf zurück an
die ZNA verwiesen, eine Person lehnte die Arztpraxis ab.
Rückläufer*innen aus Praxen in die ZNA wurden nicht
festgestellt. Das Steuerungskonzept wurde in den Interviews (n=18)
grundsätzlich positiv bewertet. Insbesondere technisches
Verbesserungspotenzial wurde identifiziert.

Schlussfolgerung Insgesamt sprechen die Ergebnisse für die
Umsetzbarkeit des Steuerungskonzepts sowie eine hohe Akzeptanz. Vor der
Weiterleitung in eine Praxis erscheint SmED hilfreich, zur Überleitung
in die Bereitschaftspraxis nach MTS hingegen verzichtbar. Die Steuerung von
Patient*innen in Arztpraxen kann die ZNA zu den Schließzeiten
der Bereitschaftspraxis entlasten. Neben der Vermittlung von Akutterminen bieten
Videokonsultationen ein zusätzliches Potenzial zum Behandlungsabschluss.
In einer Folgestudie sollte das Steuerungskonzept geringfügig angepasst
und die Angemessenheit der Weiterleitung evaluiert werden.

nur 6,5% der Befragten notfallmedizinische Angebote nannten
(8,1% bei hoher Dringlichkeit, d. h. Notfälle, die
keinen Aufschub duldeten). Die intendierte Inanspruchnahme variierte in
Abhängigkeit von der Dringlichkeit und dem Alter bzw. der
Erkrankung.

Schlussfolgerungen Es sollte verstärkt darüber
aufgeklärt werden, dass es bei dringlichen psychischen Beschwerden
notwendig ist, umgehend medizinische Hilfe aufzusuchen.
Seltenes Kompressionssyndrom des N. medianus durch den Processus
supracondylaris und das Struthers-Ligament
Authors: Tosin Davide , Antoniadis Gregor , Wirtz Christian Rainer , Pedro Maria Teresa
Published: February 2024

Einleitung Der Processus (Proc.) supracondylaris ist ein knöcherner
Fortsatz am distalen anteromedialen Humerusschaft, der eine anatomische
Rarität darstellt. Laut Studien kommt dieser lediglich bei
0,4–2,7% der Menschen vor. In nahezu allen Fällen
befindet er sich in Assoziation zu einem fibrösen, gelegentlich
verknöcherten Band, das vom Proc. supracondylaris zum Epicondylus
medialis hinreicht. Das letztere ist in der Literatur als Ligament of Struthers
bekannt und benannt nach dem schottischen Anatomen, der es im Jahre 1854 zuerst
ausführlich beschrieb. Selten kann das Vorhandensein des Ligament of
Struthers im Sinne eines Nervenkompressionssyndroms klinisch relevant werden,
wobei der N. medianus oder N. ulnaris durch die ringförmige Struktur aus
Band und Knochenfortsatz eingeengt werden können.

Fallbericht Wir berichten von einem 59-jährigen Patienten, der sich
mit Symptomen eines Kubitaltunnelsyndroms und außerdem ipsilateralen
sensiblen Defiziten am Daumen in unserer Klinik vorstellte. Elektrophysiologisch
bestand kein Anhalt für ein zusätzliches Karpaltunnelsyndrom.
Die präoperativen Röntgen- und CT-Aufnahmen des Oberarmes wiesen
einen Proc. supracondylaris auf, sodass wir ein damit assoziiertes
Medianuskompressionssyndrom vermuteten. Im MRT des Oberarmes fielen zudem ein
Ligament of Struthers und Hinweise für eine Kompression des N. medianus
durch diese anatomischen Varianten auf. Bei einer operativen Behandlung wurden
der N. medianus am distalen Oberarm und der N. ulnaris im Kubitaltunnel
dekomprimiert. Intraoperativ bestätigte sich eine deutliche Einengung
des N. medianus durch das Ligament of Struthers und den Proc. supracondylaris.
Das Ligament wurde gespalten und der Proc. supracondylaris reseziert. Drei
Monate nach der Operation bestanden keine motorischen und sensiblen
Ausfälle.

Fazit Die ringförmige Struktur bestehend aus Proc. supracondylaris
und Ligament of Struthers stellt eine seltene Ursache eines Medianus- sowie
Ulnariskompressionssyndroms dar, deren Inzidenz in der Literatur bisher
unbekannt bleibt. Diese anatomische Variante sollte aus unserer Sicht bei
entsprechenden Beschwerden nach Ausschluss anderer Nervenkompressionsstellen als
Ursache in Betracht gezogen werden. Ferner sollte bei der Operation der Proc.
supracondylaris samt Periost komplett reseziert werden, um das Risiko eines
erneuten Wachstums zu minimieren.

Tumor- and Radiation-Related Complications after Ruthenium-106 Brachytherapy in Small to Medium Uveal Melanomas (Part 1)
Authors: Lalos Fotios , Flühs Dirk , Guberina Maja , Bornfeld Norbert , Stuschke Martin , Sauerwein Wolfgang , Bechrakis Nikolaos E.
Published: February 2024

Purpose The purpose of this study was to analyze tumor-related complications after ruthenium-106 brachytherapy in patients with uveal melanoma, with respect to local tumor control, insufficient radiation response, enucleation, and metastasis rate.

Patients/Methods and Materials This retrospective study included 608 patients treated consecutively with ruthenium-106 brachytherapy between January 2008 and December 2010 at the Department of Ophthalmology, University Hospital Essen. The occurrence of radiation-induced results was analyzed by estimating the risk by applying the Kaplan-Meier method, i.e., the “time to event” analysis. The Cox model test was used for the univariate and multivariate risk factor analyses. The median follow-up was 51 months after primary treatment.

Results Tumor recurrence was found in 21 patients (3.5%) and repeated treatment due to insufficient effect after the initial ruthenium-106 brachytherapy was performed in 40 patients (6.6%). The 5-year cumulative risk of recurrence was 4.0% and that of insufficient effect was 7.3%. Thirteen patients (2.1%) underwent a secondary enucleation; 8 because of a local recurrence and 5 because of severe post-brachytherapy complications. The cumulative enucleation risk was 2.3% after 5 years and 2.9% after 10 years, corresponding to eye preservation of 97.7 and 97.1%, respectively. In forty-two patients (7.2%), metastatic disease was diagnosed during the follow-up. The metastatic rate as calculated by the Kaplan-Meier method was 9.0, and 13.1% at 5 and 10 years, respectively.

Conclusion Our study demonstrated that ruthenium-106 brachytherapy is an excellent treatment option for achieving local tumor control and eye preservation in well-selected patients. The metastatic rate is in agreement with that of previous studies analyzing small to medium size uveal melanomas.
Manganese(I)-Catalyzed C–H Allylation of Tryptophans and Their Oligopeptides On Water
Authors: Gallou Fabrice , Ackermann Lutz , Struwe Julia , Oyama Tsuyoshi
Published: February 2024

The manganese(I)-catalyzed allylation of the amino acid tryptophan is realized under exceedingly mild conditions using water as a sustainable and non-hazardous reaction medium, instead of classical organic solvents, with great potential for green and sustainable chemistry. Synthetically useful α,β-unsaturated esters can be accessed by reaction with Morita–Baylis–Hillman (MBH) adducts following a fast C–H activation approach. The robustness of this procedure is reflected by kinetic analysis at different reaction temperatures and reduced catalyst loadings are employed.
The Detailed Anatomy of the Deep Plane of the Face and Neck with Current Nomenclature
Authors: Talei Benjamin , Ziai Hedyeh
Published: February 2024

The fundamental goal of modern face and neck lifting is to enhance and restore a more youthful facial appearance by addressing soft tissue descent. There are variations in described facelift technique including superficial musculoaponeurotic system (SMAS) flaps, composite flaps, deep plane, skin flaps, and subperiosteal facelifts, among others. The term “deep plane rhytidectomy” was originally described by Hamra. This term has since been linked with facelift surgery with recent advances including incision placement, treatments of SMAS–platysma complex, and mastoid crevasse among others. In the lead authors' experience, using deep plane techniques have demonstrated superior facial surgical rejuvenation results with less dependence on ancillary measures such as fat grafting or implantation for midface volumization. In order to successfully perform any face or neck lift, it is key to understand the relationship of the skin, the fat compartments, and the ligamentous attachments. This chapter details the anatomy of the deep plane of the face and neck and explains some nuances as it relates to surgical lifting. We also describe recent anatomical revelations of the mandibular ligament and its management in deep plane face lifting. In this chapter, given this opportunity to share personal experiences and preferences, the authors hope to describe relevant anatomy for the deep plane and provide some clarity on the merits of deep plane face and neck lift technique.
HistoriView: Implementation and Evaluation of a Novel Approach to Review a Patient Using a Scalable Space-Efficient Timeline without Zoom Interactions
Authors: Park Heekyong , Wang Taowei David , Wattanasin Nich , Castro Victor M. , Gainer Vivian , Murphy Shawn
Published: February 2024

Background Timelines have been used for patient review. While maintaining a compact overview is important, merged event representations caused by the intricate and voluminous patient data bring event recognition, access ambiguity, and inefficient interaction problems. Handling large patient data efficiently is another challenge.

Objective This study aims to develop a scalable, efficient timeline to enhance patient review for research purposes. The focus is on addressing the challenges presented by the intricate and voluminous patient data.

Methods We propose a high-throughput, space-efficient HistoriView timeline for an individual patient. For a compact overview, it uses nonstacking event representation. An overlay detection algorithm, y-shift visualization, and popup-based interaction facilitate comprehensive analysis of overlapping datasets. An i2b2 HistoriView plugin was deployed, using split query and event reduction approaches, delivering the entire history efficiently without losing information. For evaluation, 11 participants completed a usability survey and a preference survey, followed by qualitative feedback. To evaluate scalability, 100 randomly selected patients over 60 years old were tested on the plugin and were compared with a baseline visualization.

Results Most participants found that HistoriView was easy to use and learn and delivered information clearly without zooming. All preferred HistoriView over a stacked timeline. They expressed satisfaction on display, ease of learning and use, and efficiency. However, challenges and suggestions for improvement were also identified. In the performance test, the largest patient had 32,630 records, which exceeds the baseline limit. HistoriView reduced it to 2,019 visual artifacts. All patients were pulled and visualized within 45.40 seconds. Visualization took less than 3 seconds for all.

Discussion and Conclusion HistoriView allows complete data exploration without exhaustive interactions in a compact overview. It is useful for dense data or iterative comparisons. However, issues in exploring subconcept records were reported. HistoriView handles large patient data preserving original information in a reasonable time.
Craniofacial Injury in a Child by Agricultural Fan Blade: A Case Report
Authors: Khan Abdul Vakil , Anwer Majid , Kumar Anurag , Kumar Anil , Ahmed Farheen
Published: February 2024

Farm machine-related injuries in children are common modality of head injury. We describe here a case of threshing fan blade injury to head and its successful management. A 10-year-old male was brought to the emergency department of All India Institute of Medical Sciences (AIIMS) Patna with the complains of accidental fall on the fan blade of the thresher machine. On arrival he had a Glasgow Coma Scale of E1VTM5 status, bilateral pupil mid-dilated and sluggish reaction to light. On secondary survey, he had a lacerated wound of size 15 × 4 × 2 cm extending from left side forehead to right temporal region exposing bone and brain parenchyma herniation through the wound. A noncontrast computed tomography head showed B/L frontal contusion with gross edema, subarachnoid hemorrhage, and intraventricular hemorrhage. There was fracture of bilateral frontal bone extending to right parietotemporal bone. Patient was taken to operating room, where after painting and draping, the wound was irrigated with normal saline. The herniated brain was removed, securing hemostasis with surgical and Bovie cautery. He underwent a prolonged neurorehabilitation and made a complete recovery after 3 months of injury. Bihar is an eastern part of India where agriculture plays a major role in rural livelihood. Winnowing fan machines are used to separate the grain from the husk. Children have peculiar behavior to inspect things and this curious behavior leads to coming in contacts with the open blade. Falling on even a stationary blade can sometimes lead to head injury. Early surgery with meticulous wound debridement and closure of dura is required. Covering the fan blade as well as careful parenting of children will prevent further injuries.
Supra- and Infratentorial Extradural Hematoma: A Series of Three Cases with Literature Review
Authors: Ranjan Nitish , Maurya Ved Prakash , Bhaisora Kamlesh Singh , Verma Pawan Kumar , Kumar Raj
Published: February 2024

The extradural hematoma (EDH) of the posterior fossa is a rare clinical condition in head injury cases. The posterior fossa extradural hematoma (PFEDH) contributes to not more than 4 to 8% of all the EDH encountered in traumatic brain injury. The limited volume of the posterior fossa leads to early clinical deterioration and, if not subjected to timely intervention, may be fatal. This rapid deterioration is because of significant compression over the brainstem and cervicomedullary junction as well as obstructive hydrocephalus. The PFEDHs are often associated with fracture of the occipital bone, which may lead to the extension of hematoma in the supratentorial and infratentorial spaces. The traumatic supra- and infratentorial EDH (TSIEDH) constitutes less than 2% of all the EDH. Limited literature is available regarding TSIEDH, and the majority are in the form of isolated case reports. We share our experience of three cases over the last 5 years from a tertiary care referral institute with a literature review of TSIEDH. Two of these cases were managed nonoperatively, and one underwent surgical evacuation of hematoma. In the present study, we share our experience regarding prompt diagnosis and management of this particular subset of traumatic brain injury patients. We also describe the surgical technique for evacuation of TSIEDH. Early diagnosis and prompt surgical intervention can be life-saving as these hematomas may have a benign clinical presentation but rapid clinical deterioration.

Published: February 2024

Urorectal septum malformation sequence (URSMS) is a rare congenital anomaly characterized by lack of perineal or anal opening, external genital defects, and various urogenital and colonic abnormalities. This condition results from deficient separation of the cloaca and the failure of the membrane to rupture. Here, we present a unique case of URSMS with prenatal diagnosis, which is extremely challenging to identify before birth. Prenatal ultrasonography revealed the presence of intraluminal enterolithiasis in the sigmoid colon, indicating high anal atresia and a vesicocolic fistula. The diagnosis was confirmed postnatally by clinical examination and ascending cystourethrogram. This case highlights the importance of prenatal screening in detecting rare congenital anomalies, and the role of ultrasonography in distinguishing enterolithiasis from other conditions. Moreover, it underscores the significance of precise fistula location determination for optimal neonatal management of anorectal malformations.
Trials, Tribulations, and Techniques for Transitioning to an Extended Deep Plane Facelift for All Patients: Insight from a Very Experienced Surgeon's Perspective
Authors: Williams Edwin F. , Urban Matthew J.
Published: February 2024

The extended deep plane facelift is a powerful technique to correct aging of the midface and neck. After many years of superficial muscular aponeurotic system lift techniques, the senior author transitioned to an extended deep plane facelift for all patients. The primary catalyst for this shift in practice was the pursuit of superior rejuvenation of the midface. Consistent uniform elevation of the deep plane with complete ligament release and management of the soft tissue flap were the most significant challenges in the early adoption period. Navigating the transition was facilitated by consultation with experienced colleagues and frequent cadaver dissections. This manuscript details the authors' current technique. Complications and recovery from this technique are similar to those reported with historical techniques and are minimized with proper preparation, precision, and perioperative management. In our experience the results from this procedure are extremely reproducible, durable, and natural, and patients are overwhelmingly extremely satisfied.

Published: February 2024

Ninetinae is a group of small to tiny short-legged spiders largely restricted to arid habitats. Among daddy-long-legs spiders (Pholcidae) this is by far the least diverse subfamily but this may partly be a result of inadequate collecting, poor representation in collections or scientific neglect. We build on a large recent collection of the ninetine genus Papiamenta Huber, 2000 from the Leeward Antilles and use cytochrome oxidase 1 (COI) sequences, extensive scanning electron microscopy data, transmission electron microscopy data and karyotyping to analyse this geographically isolated and poorly known island genus. COI sequences support the split between the two morphologically distinct species on Curaçao but genetic distances between these are surprisingly low (7.4–9.8%; mean 8.6%). The type species P. levii (Gertsch, 1982) may include more than one species but COI and morphology suggest conflicting clade limits. A third species, P. bonay Huber sp. nov. is newly described from Bonaire. Our data on sperm ultrastructure and karyology are puzzling as these suggest different phylogenetic affinities of Papiamenta to other genera. Males transfer sperm as individual sperm (cleistosperm), agreeing with the putative closest relatives as suggested by molecular data, the North American genera Pholcophora and Tolteca. The sex chromosome system (X1X2X3Y) of P. levii, however, is as in the South American Ninetinae genera Gertschiola and Nerudia but different from the putative closest relatives.

Methyltransferase Setd2 prevents T cell–mediated autoimmune diseases via phospholipid remodeling
Authors: Chen Yali , Chen Kun , Zhu Ha , Qin Hua , Liu Juan , Cao Xuetao
Published: February 2024

Coordinated metabolic reprogramming and epigenetic remodeling are critical for modulating T cell function and differentiation. However, how the epigenetic modification controls Th17/Treg cell balance via metabolic reprogramming remains obscure. Here, we find that Setd2, a histone H3K36 trimethyltransferase, suppresses Th17 development but promotes iTreg cell polarization via phospholipid remodeling. Mechanistically, Setd2 up-regulates transcriptional expression of lysophosphatidylcholine acyltransferase 4 (Lpcat4) via directly catalyzing H3K36me3 ofLpcat4gene promoter in T cells. Lpcat4-mediated phosphatidylcholine PC(16:0,18:2) generation in turn limits endoplasmic reticulum stress and oxidative stress. These changes decrease HIF-1α transcriptional activity and thus suppress Th17 but enhance Treg development. Consistent with this regulatory paradigm, T cell deficiency ofSetd2aggravates neuroinflammation and demyelination in experimental autoimmune encephalomyelitis due to imbalanced Th17/Treg cell differentiation. Overall, our data reveal that Setd2 acts as an epigenetic brake for T cell–mediated autoimmunity through phospholipid remodeling, suggesting potential targets for treating neuroinflammatory diseases.

Glucose and amino acid metabolism are critical for glioblastoma (GBM) growth, but little is known about the specific metabolic alterations in GBM that are targetable with FDA-approved compounds. To investigate tumor metabolism signatures unique to GBM, we interrogated The Cancer Genome Atlas for alterations in glucose and amino acid signatures in GBM relative to other human cancers and found that GBM exhibits the highest levels of cysteine and methionine pathway gene expression of 32 human cancers. Treatment of patient-derived GBM cells with the FDA-approved single cysteine compound N-acetylcysteine (NAC) reduced GBM cell growth and mitochondrial oxygen consumption, which was worsened by glucose starvation. Normal brain cells and other cancer cells showed no response to NAC. Mechanistic experiments revealed that cysteine compounds induce rapid mitochondrial H2O2production and reductive stress in GBM cells, an effect blocked by oxidized glutathione, thioredoxin, and redox enzyme overexpression. From analysis of the clinical proteomic tumor analysis consortium (CPTAC) database, we found that GBM cells exhibit lower expression of mitochondrial redox enzymes than four other cancers whose proteomic data are available in CPTAC. Knockdown of mitochondrial thioredoxin-2 in lung cancer cells induced NAC susceptibility, indicating the importance of mitochondrial redox enzyme expression in mitigating reductive stress. Intraperitoneal treatment of mice bearing orthotopic GBM xenografts with a two-cysteine peptide induced H2O2in brain tumors in vivo. These findings indicate that GBM is uniquely susceptible to NAC-driven reductive stress and could synergize with glucose-lowering treatments for GBM.
Pedagogical construction grammar
Authors: Pakzadian Maryam
Published: February 2024

The concept of constructions has become increasingly important in theories of language acquisition and use during
the last 20 years. Constructions are form-meaning pairings that are learned and stored as pieces of linguistic knowledge. Fillmore, Kay, and O’Conner (1988), and Goldberg (1995, 2006, 2019) were among the
first linguists who paved the way for this alternative constructivist view on grammar. Since then, Construction Grammar (CxG) has
become a widely accepted descriptive and processing model that is based on a large body of scientific research (e.g., Herbst, Schmid, & Faulhaber, 2014; Herbst,
2016; Hilpert, 2019; Hoffmann,
2022; Stefanowitsch, 2011). However, it is only recently that linguists have
addressed the question of whether second/foreign language learners’ linguistic competence depends on constructions (e.g., Boas, 2022; De Knop & Gilquin, 2016). If
CxG is widely recognized in the branch of first language acquisition, it is also indispensable to transfer this concept to Applied
Linguistics to design suitable teaching materials and methods. Drawing upon the proposition “foreign language learning is
construction learning” (Ellis, 2001; Herbst,
2016), this article aims to suggest a proposal for teaching English collocations following Herbst’s (2016) seven principles of Pedagogical Construction Grammar (PCxG). In particular, this article
aims to suggest ways to apply these principles to developing supplementary teaching materials, activities, and tasks for teaching
English collocations and collostructions.
Teaching lexical collocations to enhance speaking proficiency of college English majors in Taiwan
Authors: Hsu Jeng-yih Tim , Cheng Su-han
Published: February 2024

The present study explores lexical collocations and their relation to speaking proficiency of Taiwanese EFL
college students learning English for academic purposes (i.e., EAP). The data is obtained from 92 English majors at a national
university of science and technology in southern Taiwan. The results show that (a) direct collocation instruction promotes the
subjects’ performance on their speaking fluency tests, outscoring the other two instruction types; (b) the advanced level students
seem to benefit most as they outperformed the other three groups after receiving each of the three instruction types (i.e.,
lexical collocations, single-item vocabulary, and no instruction); and (c) no significant difference can be found between the
high-intermediate and intermediate groups with regard to their post-instruction performances. Therefore, the current study
concludes that direct collocation instruction deserves immediate attention and calls for a series of systematic studies to be done
on the possible connection between lexical collocations and English proficiency of EFL learners.
Infants’ imitative learning from third-party observations
Authors: Stenberg Gunilla
Published: February 2024

In two separate experiments, we examined 17-month-olds’ imitation in a third-party context. The aim was to explore
how seeing another person responding to a model’s novel action influenced infant imitation. The infants watched while a reliable
model demonstrated a novel action with a familiar (Experiment 1) or an unfamiliar (Experiment 2) object to a second actor. The
second actor either imitated or did not imitate the novel action of the model. Fewer infants imitated the model’s novel behavior
in the non-imitation condition than in the imitation condition in Experiment 1. In Experiment 2, infants’ likelihood of imitating
was not influenced by whether they had watched the second actor imitating the model’s novel action with the unfamiliar object. The
findings indicate that infants take into account a second adult’s actions in a third party context when infants receive
information that contradicts their existing knowledge and when it corresponds with their own experiences. If infants do not have
prior knowledge about how to handle a certain object, then the second adult’s actions do not seem to matter.
A matter of consequences

On reviewing the literature regarding acceptance and trust in human-robot interaction (HRI), there are a number of
open questions that needed to be addressed in order to establish effective collaborations between humans and robots in real-world
applications. In particular, we identified four principal open areas that should be investigated to create guidelines for the
successful deployment of robots in the wild. These areas are focused on: (1) the robot’s abilities and limitations; in particular
when it makes errors with different severity of consequences, (2) individual differences, (3) the dynamics of human-robot trust,
and (4) the interaction between humans and robots over time. In this paper, we present two very similar studies, one with a
virtual robot with human-like abilities, and one with a Care-O-bot 4 robot. In the first study, we create an immersive narrative
using an interactive storyboard to collect responses of 154 participants. In the second study, 6 participants had repeated
interactions over three weeks with a physical robot. We summarise and discuss the findings of our investigations of the effects of
robots’ errors on people’s trust in robots for designing mechanisms that allow robots to recover from a breach of trust. In
particular, we observed that robots’ errors had greater impact on people’s trust in the robot when the errors were made at the
beginning of the interaction and had severe consequences.

Our results also provided insights on how these errors vary according to the individuals’ personalities,
expectations and previous experiences.

Previous research shows that females use more exclamation marks than males, often to establish rapport. The purpose of the present studies was to test whether people associate texters’ use of exclamation marks with friendliness and femaleness. If this association is due to normative expectations, we hypothesized that females would appear less friendly if they did not use an exclamation mark in texting. In Study 1, participants rated a texter using an exclamation mark to be highly female and highly friendly. The gender results disappeared when friendliness was controlled for. In Study 2, we tested whether friendliness ratings decreased if texters violated gender-associated punctuation. Participants rated a texter with a gendered name on friendliness. Regardless of gender, participants inferred greater friendliness to texters using an exclamation mark. That is, there was no evidence of a cost for violating this gender expectation. We conclude that people predict that a texter using an exclamation mark is likely to be female, but do not penalize females for not using an exclamation mark.

Published: February 2024

Thermally induced magnetization switching (TIMS) relying solely on a single laser without any applied magnetic field is a key research direction of current spintronics. Most studies on TbFe so far have focused on helicity-dependent all-optical switching (HD-AOS). In this work, we observe the TIMS on TbFe alloys excited by atomic spin dynamics simulations combined with a two-temperature model. The results show that the magnetization switching of TbFe can be found under certain damping conditions. In addition, we further investigated the reasons why energy density leads to the opposite switching time behavior of Tb and Fe, and our research results also found that changes in damping can affect the concentration and energy density range of the switching, as well as the maximum pulse duration. The dynamic behavior indicates that TbFe switching in 2 ps or less. Our findings widen the basis for fast optical switching of magnetization and break new ground for engineered materials that can be used for nonvolatile ultrafast switching using ultrashort pulses of light.
SVM bearing fault diagnosis based on fast inter-class distance in the feature space and DMPSO algorithm

Published: February 2024

Support vector machines (SVMs) have good processing performance for small sample datasets. The giant search space for kernel parameters and the tendency of parameter optimization to fall into local optima are two essential factors that affect the generalization ability of SVM models and, thus, affect the accuracy of fault diagnosis results. Propose using fast inter-class distance (FICDF) in the feature space to reduce the search space for kernel function parameters and then use differential mutation particle swarm optimization (DMPSO) to optimize kernel function parameters to improve the generalization ability and classification accuracy of the SVM model. Firstly, the FICDF algorithm is used to calculate the Euclidean distance between classes, and a fast segmentation idea is proposed for fast operations to obtain a smaller kernel parameter search space. Then, the global search ability of the DMPSO algorithm is used to obtain the optimal parameter combination of the SVM model. Finally, the fault diagnosis model of the SVM is applied to the fault diagnosis of rolling bearings. The experimental results show that compared with other fault diagnosis methods, this model method has higher classification accuracy and verifies its better classification speed.
Study on the variation law of shock wave on the surface of landmine shell under touchdown explosion
Authors: Chen Jiahui , Kong Deren
Published: February 2024

To study the variation law of shock wave pressure load on the surface of a certain type of landmine installed on the ground when explosive contact ground explosion, the TNT (C7H5N3O6) contact ground explosion experiments were conducted. Using the pressure test device that simulates the shape of a certain type of landmine to test the shock wave pressure load on its side and top surface respectively. Combined with the numerical simulation, studied the variation law of shock wave overpressure peak, positive pressure action time, and specific impulse on the side and top surface of the landmines at different scaled distances. The results show that the scaled distance less than 1.453 m/ kg1/3 is the range of near-range explosion. In this range, the shock wave pressure time history curve shows multiple peaks due to the combined action of the shock wave and detonation products. The closer to the explosion source, the pressure peak generated by the detonation product is significantly higher than the shock wave pressure peak, and the propagation speed of the shock wave is faster than that of detonation products. With the further increase of the blast center distance, the positive pressure action time of the shock wave on the side and top surface of the landmine it was increased significantly. The specific impulse of the shock wave on the side of the landmines is significantly higher than that on the top surface of the device at the same scaled distance. In the range of scaled distance less than 1.937 m/kg1/3, the specific impulse of the shock wave on both the side and top surfaces of the landmines increases at first and then decreases later, and its variation curve shows an obvious triangle. With the increase of the explosive quality, the rate of rise and attenuation of specific impulse of the shock wave is faster. With the further increase of blasting center distance, the specific impulse of the shock wave on the side and the top surface of the landmines tends to be equal at the same scaled distance, the continuous range is wide, and the explosive quality has little effect on it.
