Using music reviews in the intermediate L2 German classroom: An exploratory lesson in genre‐based writing
Authors: Strietholt Sophia , Larson‐Guenette Julie , Fox Gemini 
Published: January 2024

AbstractThis article presents an exploratory genre‐based writing lesson conducted in a third‐year collegiate German language course. While genre‐based approaches to writing have gained recognition in second language (L2) contexts, little attention has been given to learner perceptions of genre‐based writing activities. Additionally, there is a lack of pedagogical strategies and materials for intermediate‐level German language classes. This article addresses these gaps by introducing a lesson on consumer music reviews designed following genre‐based pedagogical principles, the flipped classroom approach, and the use of language corpora. The lesson, consisting of two 75‐min class periods, aimed at familiarizing students with the structure and style of consumer music reviews, culminating in the writing of their own reviews. Using authentic texts and incorporating the Digitales Wörterbuch der deutschen Sprache corpus tool for vocabulary building, students engaged with contemporary German‐language music. Data from student surveys indicated positive perceptions of the lesson, particularly regarding vocabulary acquisition, lesson structure, and topic relevance. Students also found the corpus tool beneficial for contextual understanding and word usage. This exploratory lesson highlights the potential of genre‐based writing pedagogy, the flipped classroom model, and corpus tools for L2 writing development and contributes to the growing body of literature on genre‐based writing in L2 classrooms.
‘Against all floods’: plant adaptation to flooding stress and combined abiotic stresses
Authors: Renziehausen Tilo , Frings Stephanie , Schmidt‐Schippers Romy 
Published: January 2024

SUMMARYCurrent climate change brings with it a higher frequency of environmental stresses, which occur in combination rather than individually leading to massive crop losses worldwide. In addition to, for example, drought stress (low water availability), also flooding (excessive water) can threaten the plant, causing, among others, an energy crisis due to hypoxia, which is responded to by extensive transcriptional, metabolic and growth‐related adaptations. While signalling during flooding is relatively well understood, at least in model plants, the molecular mechanisms of combinatorial flooding stress responses, for example, flooding simultaneously with salinity, temperature stress and heavy metal stress or sequentially with drought stress, remain elusive. This represents a significant gap in knowledge due to the fact that dually stressed plants often show unique responses at multiple levels not observed under single stress. In this review, we (i) consider possible effects of stress combinations from a theoretical point of view, (ii) summarize the current state of knowledge on signal transduction under single flooding stress, (iii) describe plant adaptation responses to flooding stress combined with four other abiotic stresses and (iv) propose molecular components of combinatorial flooding (hypoxia) stress adaptation based on their reported dual roles in multiple stresses. This way, more future emphasis may be placed on deciphering molecular mechanisms of combinatorial flooding stress adaptation, thereby potentially stimulating development of molecular tools to improve plant resilience towards multi‐stress scenarios.

SUMMARYSpecific ecological conditions in the high mountain environment exert a selective pressure that often leads to convergent trait evolution. Reticulations induced by incomplete lineage sorting and introgression can lead to discordant trait patterns among gene and species trees (hemiplasy/xenoplasy), providing a false illusion that the traits under study are homoplastic. Using phylogenetic species networks, we explored the effect of gene exchange on trait evolution in Soldanella, a genus profoundly influenced by historical introgression. At least three features evolved independently multiple times: the single‐flowered dwarf phenotype, dysploid cytotype, and ecological generalism. The present analyses also indicated that the recurring occurrence of stoloniferous growth might have been prompted by an introgression event between an ancestral lineage and a still extant species, although its emergence via convergent evolution cannot be completely ruled out. Phylogenetic regression suggested that the independent evolution of larger genomes in snowbells is most likely a result of the interplay between hybridization events of dysploid and euploid taxa and hostile environments at the range margins of the genus. The emergence of key intrinsic and extrinsic traits in snowbells has been significantly impacted not only by convergent evolution but also by historical and recent introgression events.

AbstractMediastinal cysts (MCs) are rare lesions that can arise from embryonic remnants of various mediastinal structures. MCs usually are incidental findings in dogs and cats; however, they can reach a mass‐like appearance. The description of MCs on CT in dogs is limited. This retrospective, single‐center, descriptive, prevalence study aimed to determine the prevalence of presumed mediastinal cysts (PMCs) in dogs and assess their CT characteristics. Dogs that underwent a thoracic CT scan from January 2019 to August 2021 were included. CT images were evaluated for the presence of PMCs by two diagnostic imaging interns, two last year diagnostic imaging residents, and a board‐certified veterinary radiologist. Number, location, margins, shape, volume, size, mass effect, and attenuation values of PMCs were assessed. A total of 866 CT scans were reviewed, and 49 PMCs were identified. The prevalence of PMCs in dogs was 5.66%. English Bulldog and mixed‐breed dogs were subjectively overrepresented; however, the possibility of population bias could not be excluded. PMCs were subjectively more frequently observed in male dogs. The PMCs were predominantly round, small, solitary fluid‐filled findings localized in the cranioventral mediastinum, with well‐defined margins, homogeneous attenuation, and no contrast enhancement. The median attenuation value was 6.32 HU (range: −20.16 to 23.45 HU) precontrast and 7.58 HU (range: −2.45 to 20.79 HU) postcontrast, and the median volume was 1.19 cm3 (range: 0.02–45.32 cm3). Although the prevalence of PMCs was low in our sample population, findings supported prioritizing a differential diagnosis of incidental PMC for dogs with the above imaging characteristics.

Published: January 2024

AbstractChronic wounds are a common and costly health issue affecting millions of individuals in the United States, particularly those with underlying conditions such as diabetes, venous insufficiency, and peripheral artery disease. When standard treatments fail, advanced wound care therapies, such as skin substitutes, are often applied. However, the clinical effectiveness, indications, and comparative benefits of these therapies have not been well established. In this study, we report on the usage of both acellular and cellular, single and bilayer, natural and synthetic, dermal, and epidermal skin substitutes in a VA hospital system. We performed a retrospective chart review to understand the ordering and usage patterns of advanced wound therapies for patients with chronic wounds at the VA Northern California Health Care System. We examined types of products being recommended, categories of users recommending the products, indications for orders, and rate of repeated orders. Neuropathic, venous, or pressure ulcers were the main indications for using advanced wound matrices. Only 15.6% of patients for whom the matrices were ordered had supporting laboratory tests. Exactly 34.3% of the ordered matrices were not applied. And the use of wound matrices resulted in increased costs per patient visit of $1018–$3450. Our study sheds light on the usage patterns of these therapies in a VA healthcare facility and highlights the need for more robust evidence‐based studies to determine the true benefits, efficacy, and cost‐effectiveness of these innovative treatment options.

A unified half‐integral Erdős–Pósa theorem for cycles in graphs labelled by multiple abelian groups
Authors: Gollin J. Pascal , Hendrey Kevin , Kawarabayashi Ken‐ichi , Kwon O‐joung , Oum Sang‐il 
Published: January 2024

AbstractErdős and Pósa proved in 1965 that there is a duality between the maximum size of a packing of cycles and the minimum size of a vertex set hitting all cycles. Such a duality does not hold if we restrict to odd cycles. However, in 1999, Reed proved an analogue for odd cycles by relaxing packing to half‐integral packing. We prove a far‐reaching generalisation of the theorem of Reed; if the edges of a graph are labelled by finitely many abelian groups, then there is a duality between the maximum size of a half‐integral packing of cycles whose values avoid a fixed finite set for each abelian group and the minimum size of a vertex set hitting all such cycles. A multitude of natural properties of cycles can be encoded in this setting, for example, cycles of length at least , cycles of length modulo , cycles intersecting a prescribed set of vertices at least times and cycles contained in given ‐homology classes in a graph embedded on a fixed surface. Our main result allows us to prove a duality theorem for cycles satisfying a fixed set of finitely many such properties.
Oversizing Novel Aircraft Propulsion Systems for Power Redundancy

Published: January 2024

Abstract
This paper expands the one-engine-inoperative conventional oversizing consideration to account for aircraft propulsion systems with multiple energy sources and thrust-generating media. Components in a generic hybrid propulsion system are categorized into power-generation, power-transmission, and thrust-generation. For a given architecture, each possible single component failure is simulated to identify elements affected or eliminated by the respective loss of power, through the use of connection matrices. Failures are linked to losses in supplied and propulsive power, creating a list of oversizing factors for all individual components. Each element is oversized according to its corresponding maximum oversizing rate, defining the ideally redundant propulsion system. Case studies for conventional, all-electric, and hybrid-electric powertrains highlight the need for balancing the number of components between minimizing excess power and increasing the probability of a failure. Additionally, it is shown that asymmetrical configurations should not have a major imbalance of power to avoid significant oversizing. The proposed methodology is applied to a 19-passenger, commuter aircraft. Increasing oversizing rate close to ideal leads to lower optimum energy consumption and boosts redundancy. However, payload capacity penalties are required, up to four passengers for ideal oversizing. Heavier variants without penalties are up to 4% more efficient in terms of energy-per-weight in their carrying capacity against counterparts of the same oversize rate with reduced payload capacity. The proposed method maintains the principles of the conventional oversizing process and highlights the tradeoffs needed between redundancy and performance in sizing novel propulsion systems.

Abstract
The Lawrence Livermore National Laboratory (LLNL) will soon have in place the El Capitan exascale supercomputer, based on advanced micro devices (AMD) graphics processing units (GPUs). As part of a multiyear effort under the National Nuclear Security Administration (NNSA) Advanced Simulation and Computing (ASC) program, we have been developing marbl, a next generation, performance portable multiphysics application based on high-order finite elements. In previous years, we successfully ported the Arbitrary Lagrangian–Eulerian (ALE), multimaterial, compressible flow capabilities of marbl to nvidia GPUs as described in Vargas et al. (2022, “Matrix-Free Approaches for GPU Acceleration of a High-Order Finite Element Hydrodynamics Application Using MFEM, Umpire, and RAJA,” Int. J. High Perform. Comput. Appl., 36(4), pp. 492–509). In this paper, we describe our ongoing effort in extending marbl's GPU capabilities with additional physics, including multigroup radiation diffusion and thermonuclear burn for high energy density physics (HEDP) and fusion modeling. We also describe how our portability abstraction approach based on the raja Portability Suite and the mfem finite element discretization library has enabled us to achieve high performance on AMD based GPUs with minimal effort in hardware-specific porting. Throughout this work, we highlight numerical and algorithmic developments that were required to achieve GPU performance.
Peculiarities for domain walls in Taub coordinates
Authors: Lanosa Leandro , Santillón Osvaldo Pablo 
Published: January 2024

AbstractIn the present letter the infinite domain wall geometry in GR (Vilenkin in Phys Rev D 23:852, 1981; Vilenkin in Phys Lett B 133:177, 1983; Ipser and Sikivie in Phys Rev D 30:712, 1984) is reconsidered in Taub coordinates (Taub in Ann Math 53:472, 1951). The use of these coordinates makes explicit that the regions between the horizons and the wall and the outer ones are flat. By use of these coordinates, it is suggested that points inside the horizon and outside never communicate each other. The wall is seen on the left and the right side as contracting and expanding portions of spheres and a plane singularity, which is the imprint the contracting and expanding domain wall. Particles of each region will never reach this imprint. In addition, at some point during the evolution of the system, four curious holes inside the space time appear, growing at the speed of light. This region is not parameterized by the standard Taub coordinates, and the boundary of this hole adsorbs all the particles that intersect it. The boundary of these holes are composed by points which in the coordinates of [1–3] are asymptotic, in the sense that they correspond to trajectories tending to infinite values of the time or space like coordinates, while the proper time elapsed for the travel is in fact finite. This is not paradoxical, as the coordinates [1–3] are not to be identified with the true lengths or proper time on the space time. The correct interpretation of the boundary is particularity relevant when studying scattering of quantum fields approaching the domain wall. A partial analysis about this issue is done in the last section.

Published: January 2024

Abstract
Heteroptera belongs to a group of highly diversified insect forms ranging from plant feeders, blood-feeders, predators, scavengers, detritivores, and fungivores with terrestrial or aquatic habitats. These insects have been used in entomophagy and entomotherapeutic practices. Edible insects are a source of essential bioactive secondary metabolites and bioactive peptides, having nutraceutical potential to deal with metabolic disorders. Various venomous peptides from heteropterans with therapeutic properties have been reported and are constantly being investigated for various medical conditions. This review enlists heteropteran edible insects and bioactive peptides identified from heteropterans for use as an alternative medicine. The heteropteran categories and feeding habits have been briefly outlined. The role of bioinformatics in putting up a translational aspect of insect venom has been discussed. Further, the possible exploration of therapeutic function-based proteins and peptides and the need for advanced studies using modern bioinformatics tools, and scientific validation processes are also discussed.
Education Research and Audiovisual Production: The Emergence of Minor Stories in Postmedia Society
Authors: Armella Julieta , Dafunchio Sofia 
Published: January 2024

Abstract
The authors discuss findings from an educational research study carried out in a secondary school of the Buenos Aires Metropolitan Region based on creative research methods and on a collaborative audiovisual project. They inquire into the forms education takes in a postmedia society and they explore the possibilities of the school as time-space to reflect upon the world by means of experimenting with diverse languages and techniques. Here the authors analyze audiovisual materials produced by students and suggest three analytic categories—the scream, the testimony and the singular experience—which are related by an incident that took place in the students’ neighborhood, known as the “Carcova Massacre”. The authors hypothesize that when this event is narrated in the first person by the students—who witnessed the death of their two young neighbors—, the story reported by the media as a police incident becomes a minor story, making it a lived story.
Audiovisual Storytelling in Secondary Schools Located in the Slums of the Buenos Aires Metropolitan Region
Authors: Grinberg Silvia 
Published: January 2024

Abstract
School in postmedia society falls prey to “systemic stupidity” (Stiegler, 2011), while the teacher-cum-coach heeds what is considered the new divine calling for education. In this framework, this video-article looks to elements from research that the author believes might serve as a roadmap for work with words and images in schools that lie beyond that stupidity. Through the audiovisual narratives of students in secondary schools located in a slum in the Buenos Aires Metropolitan Area, the author explores possible approaches to the question of the audiovisual narrative in school and how school is or, rather, can continue to be the repository of the hopes that critical thought harbors. More specifically, the author asks whether audiovisual narratives can contribute to more complex conceptions of the world that help us go beyond the binary logics and infantilization.

Background The Rural Trauma Team Development Course (RTTDC) is designed to help rural hospitals better organize and manage trauma patients with limited resources. Although RTTDC is well-established, limited literature exists regarding improvement in the overall objectives for which the course was designed. The aim of this study was to analyze the goals of RTTDC, hypothesizing improvements in course objectives after course completion. Methods This was a prospective, observational study from 2015 through 2021. All hospitals completing the RTTDC led by our Level 1, academic trauma hospital were included. Our institutional database was queried for individual patient data. Cohorts were delineated before and after RTTDC was provided to the rural hospital. Basic demographics were obtained. Outcomes of interest included: Emergency Department (ED) dwell time, decision time to transfer, number of total images/computed tomography scans obtained, and mortality. Chi square and non-parametric median test were used. Significance was set at P < .05. Results Sixteen rural hospitals were included with a total of 472 patients transferred (240 before and 232 after). Patient demographics were similar before and after RTTDC. ED dwell time was significantly reduced by 64 min ( P = .003) and decision to transfer time was cut by 62 min ( P = .004) after RTTDC. Mean total radiographic images and CT scans were significantly reduced ( P < .001 and P = .002, respectively) after RTTDC. Mortality was unaffected by RTTDC completion ( P = .941). Conclusion The RTTDC demonstrates decreased ED dwell time, decision time to transfer, and number of radiographic images obtained prior to transfer. More rural hospitals should be offered this course.

Introduction This study aims to evaluate program signaling in surgical specialties, analyze its influence on residency applications, and provide recommendations for enhancing its consistency and effectiveness. Methods This cross-sectional study analyzed AAMC ERAS data from the 2021 to 2022 and 2023 residency match cycles, focusing on surgical specialties including general surgery, neurological surgery, obstetrics and gynecology, and orthopedic surgery. Results A positive correlation existed between the number of signals received and the number of applicants to a program across 4 surgical specialties. 10% of programs in each specialty received between 17% and 28% of all signals. There was a negative correlation between the number of current DO residents at a program and the number of signals received. Amongst surgical specialties, those with more signals per applicant had a more equitable distribution of signals across competitive programs. University programs received the most signals, programs were less likely to receive signals if they had a higher percentage of DO residents, and IMG applicants were less likely to send signals. Conclusion Specialties with more signals per applicant had a more equitable distribution of signals across competitive programs, and university programs received proportionally more signals than community programs. Further research is required to investigate the disparities in signaling and the impact of signaling on successful matching.
