Exploring Assumptions of the Bilingual Delay in Children With and Without Developmental Language Disorder
Authors: Peña Elizabeth D. , Bedore Lisa M. , Vargas Alejandro Granados 
Published: September 2023

Purpose:
Bilingual children are both over- and under-identified with developmental language disorder (DLD). We propose that this may be a function of monolingual approaches that fail to consider the dynamic nature of bilingualism as well as assumptions of bilingual delay. We explored the extent to which bilingual children with and without DLD demonstrated mixed dominance as a function of exposure to English. We document patterns of performance in bilingual children with and without DLD on the Bilingual English–Spanish Assessment or Bilingual English–Spanish Assessment–Middle Extension in Spanish, English, and their best language scores.

Method:
A total of 595 (100 with DLD) Spanish–English bilingual children between the ages of 5 and 12 years were included in the analyses. We employed logistic regression to evaluate the probability of demonstrating mixed dominance across semantics and morphosyntax in Spanish and English by ability status. We then evaluated the association between English exposure and performance in Spanish, English, and the best language on semantics and morphosyntax measures.

Results:
There were similar typically developing and DLD probabilities of Spanish or English dominance associated with high degrees of Spanish and English exposure. Mixed dominance was associated with both ability and exposure. Children with DLD demonstrated more mixed dominance from 0% to 60% English exposure. The patterns of mixed dominance were similar by ability when they had more than 60% exposure to English. There were significant associations between single language testing in Spanish and English with percentage of exposure for children with and without DLD. When the best score (comparing English and Spanish) was used, there were no significant associations with exposure for semantics or morphosyntax.

Conclusions:
These results inform researchers and clinicians about the nature of bilingual proficiency in children with and without DLD. Mixed dominance was observed in both groups but with different patterns at lower levels of English exposure in children with and without DLD. We also see that when children's best score is considered, all differences in performance along the bilingual continuum are related to ability not language exposure. This has implications for how to consider children's language test scores in making clinical decisions about bilingual children.

Scaled p‐norm and its application in fast time‐synchronized control
Authors: Wang Shaocong , Su Chuxiong , Chang Jing , Dai Hao , Li Jing 
Published: September 2023

AbstractThe definition of scaled p‐norm and its properties are given here. Compared with the norm‐normalized sign function, using scaled p‐norm in the controller design can not only achieve the time‐synchronized stability of non‐linear dynamic systems, but also improve the convergence rate of the system. Besides, the scaled p‐norm is applied to design the consensus protocol for multi‐agent systems, which enables the states of all agents to achieve fast time‐synchronized consensus. The simulation results demonstrate the superiority of this method in improving the convergence rate of the system.

AbstractThe multiphase matrix converter outperforms the conventional three‐phase system with higher fault tolerance capability and higher power control competency. This paper discusses the direct control based on different possible switching combinations of a three‐phase to five‐phase matrix converter (MC). The proposed control topology significantly reduces the switching commutations in a switching cycle when compared with its counterpart. The control is based on the modified space vector pulse width modulation (SVPWM) strategy. The proposed space vector scheme intelligently selects the voltage vectors to get the desired output characteristics with the least possible switching transitions in a switching cycle. Three possible cases exist in controlling space vectors based on their magnitude, the number of active switching vectors, and their commutations. The results for three different cases of SVPWM have been presented and compared. The total harmonic distortion (THD) obtained in the output is lower in case 2; however, it suffers from a higher common‐mode voltage (CMV). The scheme has been successfully implemented and verified in hardware.

Published: September 2023

AbstractSARS‐CoV‐2 epidemic (severe acute respiratory corona virus 2 syndromes) has caused major impacts on a global scale. Several countries, including India, Europe, U.S.A., introduced a full state/nation lockdown to minimise the disease transmission through human interaction after the virus entered the population and to minimise the loss of human life. Millions of people have gone unemployed due to lockdown implementation, resulting in business and industry closure and leading to a national economic slowdown. Therefore, preventing the spread of the COVID‐19 virus in the world while also preserving the global economy is an essential problem requiring an effective and immediate solution. Using the compartmental epidemiology S, E, I, R or D (Susceptible, Exposed, Infectious, Recovery or Death) model extended to multiple population regions, the authors predict the evolution of the SARS‐CoV‐2 disease and construct an optimally scheduled lockdown calendar to execute lockdown over phases, using the well‐known Knapsack problem. A comparative analysis of both classical and quantum models shows that our model decreases SARS‐CoV‐2 active cases while retaining the average global economic factor, Gross Domestic Product, in contrast to the scenario with no lockdown.

Published: September 2023

(J. Extra-Corpor. Technol. 19[3] p. 305-311 Fall 1987, 11 ref.) To promote the development of heart transplantation by developing a complete technique of prolonged preservation of the graft in an independent, miniaturized and computerized container, a surgical technique is described, which allows continuous protection of the myocardium during removal, preservation and grafting.
The use of cardioplegia allows diastole arrest, an essential point for good preservation. The preservation system consists of a refrigerated and thermostatic container. The heart is perfused by a micropump and the perfusate is oxygenated and bubblefree due to a special filter. Captors are placed in the perfusion, thermic catheter, K ++, pH, lactate, electrodes and the results are analyzed by a microcomputer and transmitted to a feedback control system which adjusts the parameters. This device can be portable. With this type of device, good results were obtained as evidenced by:
• ckmb release was low
• the histological lesions are rare and reversible
• after transport, the heart maintains electrical and mechanical activity.
The Roller Pump Does Produce Pulsatile Flow

Published: September 2023

(J. Extra-Corpor. Technol. 19[3] p. 376-383 Fall 1987, 15 ref.) This study was undertaken to investigate, under experimental conditions, the nature of the roller pump output. Pressure and flow studies were done on 200° roller pumps using PVC and silastic formulations in the raceway. Polyvinyl chloride (PVC) tubing in all sizes produced comparatively higher pressure levels with narrow pressure spikes. Small bore tubing with high revolutions per minute (RPMs) delivered characteristic pulseless flow due to telescoping of flow and pressure pulses. Large bore PVC tubing produced pulsatile flow curves with spikes, ripples and artifacts. Silastic and fluorocarbon tubing achieves pulsatile flow curves without ripples or artifacts at a comparatively lower pressure range. A wide pulse width and a single roller ripple chararacterize it. Ideal combinations used clinically in over 1,500 cases result in appreciable pulse flow measurable in significant changes in renal output both in normothermic and hypothermic conditions.
These results show that a regular roller pump, with the use of tubing with specific viscoelastic properties and the proper choice of stroke volume, will produce a significant level of pulsatile flow. There is no need for an add-on system. Preliminary work utilizing a single roller pump, as a means of enhancing the pulse wave, is presented. Techniques to remove the 200° single roller induced ripple is also discussed.

ZusammenfassungDas Debridement chronischer Wunden ist eine Voraussetzung für die Wundheilung. Eine der Optionen, um Debris, Nekrosen oder posttraumatische Fremdkörper zu entfernen, ist die Hydrochirurgie in Anästhesie und in einem sterilen OP-Umfeld. Diese chirurgische Maßnahme ist z.B. geeignet für chronische Beinulzera, aber auch für Verbrennungen, nekrotische Wunden, Fremdmaterialeinsprengungen, axilläre Osmosis und Phyme bei Rosazea. Die Studienlage zeigt einige wenige, aber kontrollierte Studien und Metaanalysen. Für dieses chirurgische Gerät mit einem Einmal-Handstück sind die Kosten zwar hoch wegen des Verbrauchsmaterials, aber die Zeitersparnis ist belegt und kann gegengerechnet werden. Das Absaugen des debridierten Materials, welche das Gerät während der Maßnahme leistet, ist für den Operateur angenehm.
Tracking the acceptance of neologisms in German: Psycholinguistic factors and their correspondence with corpus-linguistic findings
Authors: Wolfer Sascha , Klosa-Kückelhaus Annette 
Published: September 2023

AbstractNeologisms, i.e., new words or meanings, are finding their way into everyday language use all the time. In the process, already existing elements of a language are recombined or linguistic material from other languages is borrowed. But are borrowed neologisms accepted similarly well by the speech community as neologisms that were formed from “native” material? We investigate this question based on neologisms in German. Building on the corresponding results of a corpus study, we test the hypothesis of whether “native” neologisms are more readily accepted than those borrowed from English. To do so, we use a psycholinguistic experimental paradigm that allows us to estimate the degree of uncertainty of the participants based on the mouse trajectories of their responses. Unexpectedly, our results suggest that the neologisms borrowed from English are accepted more frequently, more quickly, and more easily than the “native” ones. These effects, however, are restricted to people born after 1980, the so-called millenials. We propose potential explanations for this mismatch between corpus results and experimental data and argue, among other things, for a reinterpretation of previous corpus studies.

Published: September 2023

The validity of local thermodynamic equilibrium (LTE) in plasma is a long-term concern for laser-induced breakdown spectroscopy applications. In this paper, the spatial and temporal dependence of LTE deviation in picosecond laser-induced plasmas has been proved. A picosecond (∼20 ps) laser operated at 532 nm was used to ablate a silicon target to produce plasma at a pressure of 10−5 mbar. A general electron energy distribution function was used to provide access to the insight into population ratios of different energy levels for the spatially and temporally resolved optical emission intensity of laser-induced plasma. A precise temporal and spatial LTE boundary of plasma generated in picosecond laser ablation was obtained, and the results showed that only at delay times of 180–300 ns, the plasma away from the surface (&gt;4 mm) is in LTE.

Published: September 2023

Abstract
The rich nature of van der Waals interactions between artificially-stacked atomic layers has been demonstrated by various quantum states and resonant tunneling transport in low-dimensional materials. However, the role of topological fluctuations in quantum transport through artificially-stacked junctions of 2D superconducting materials, and the resulting energy dissipation, remain elusive. In this research, unique phase-slip centers are designed in artificially-stacked junction areas, where nonequilibrium quasiparticles are formed and relaxed with energy dissipation. The phase slips are observed as voltage steps (peaks or valleys) in transport measurements across a junction between two exfoliated NbSe2 flakes, and at a distance of 4 μm from the junction using local and nonlocal chemical potential probes. Accordingly, two types of energy dissipation modes are newly identified in the artificially-stacked NbSe2 when subjected to an in-plane magnetic field, which implies distinct vortex formation and current flow in the superconducting junction under magnetic fields.

Published: September 2023

Abstract
This work reports a nanostructure resonant tunnelling diode-photodetector (RTD-PD) device and demonstrates its operation as a controllable, optically-triggered excitable spike generator. The top contact layer of the device is designed with a nanopillar structure (500 nm in diameter) to restrain the injection current, yielding therefore lower energy operation for spike generation. We demonstrate experimentally the deterministic optical triggering of controllable and repeatable neuron-like spike patterns in the nanostructure RTD-PDs. Moreover, we show the device’s ability to deliver spiking responses when biased in either of the two regions adjacent to the negative differential conductance region, the so-called ‘peak’ and ‘valley’ points of the current–voltage (I–V) characteristic. This work also demonstrates experimentally key neuron-like dynamical features in the nanostructure RTD-PD, such as a well-defined threshold (in input optical intensity) for spike firing, as well as the presence of spike firing refractory time. The optoelectronic and chip-scale character of the proposed system together with the deterministic, repeatable and well controllable nature of the optically-elicited spiking responses render this nanostructure RTD-PD element as a highly promising solution for high-speed, energy-efficient optoelectronic artificial spiking neurons for novel light-enabled neuromorphic computing hardware.
Advances in understanding the changes of tropical rainfall annual cycle: a review
Authors: Song Fengfei , Leung L Ruby , Lu Jian , Zhou Tianjun , Huang Ping 
Published: September 2023

AbstractAided by progress in the theoretical understanding, new knowledge on tropical rainfall annual cycle changes under global warming background has been advanced in the past decade. In this review, we focus on recent advances in understanding the changes of tropical rainfall annual cycle, including its four distinct features: amplitude, pattern shift, phase and wet/dry season length changes. In a warming climate, the amplitude of tropical rainfall annual cycle is enhanced, more evidently over ocean, while the phase of tropical rainfall annual cycle is delayed, mainly over land. The former is explained by the wet-get-wetter mechanism and the latter is explained by the enhanced effective atmospheric heat capacity and increased convective barrier. The phase delay over land has already emerged in the past four decades. The pattern shift under warming is marked by two features: equatorward shift of the inter-tropical convergence zone throughout the year and the land-to-ocean precipitation shift in the rainy season. The former is explained by the upped-ante mechanism and/or related to the enhanced equatorial warming in a warmer world. The latter is suggested to be caused by the opposite land and ocean surface temperature annual cycle changes in the tropics. Over tropical rainforest regions such as Amazon and Congo Basin, the dry season has lengthened in the recent decades, but the fundamental reason is still unclear. Despite the notable progress of the last decade, many gaps remain in understanding the mechanism, quantifying and attributing the emergence, narrowing the inter-model uncertainty, and evaluating the impact of tropical rainfall annual cycle changes, motivating future work guided by some directions proposed in this review.
AliSim-HPC: parallel sequence simulator for phylogenetics
Authors: Ly-Trong Nhan , Barca Giuseppe M J , Minh Bui Quang 
Published: September 2023

Abstract

Motivation
Sequence simulation plays a vital role in phylogenetics with many applications, such as evaluating phylogenetic methods, testing hypotheses, and generating training data for machine-learning applications. We recently introduced a new simulator for multiple sequence alignments called AliSim, which outperformed existing tools. However, with the increasing demands of simulating large data sets, AliSim is still slow due to its sequential implementation; for example, to simulate millions of sequence alignments, AliSim took several days or weeks. Parallelization has been used for many phylogenetic inference methods but not yet for sequence simulation.

Results
This paper introduces AliSim-HPC, which, for the first time, employs high-performance computing for phylogenetic simulations. AliSim-HPC parallelizes the simulation process at both multi-core and multi-CPU levels using the OpenMP and message passing interface (MPI) libraries, respectively. AliSim-HPC is highly efficient and scalable, which reduces the runtime to simulate 100 large gap-free alignments (30 000 sequences of one million sites) from over one day to 11 min using 256 CPU cores from a cluster with six computing nodes, a 153-fold speedup. While the OpenMP version can only simulate gap-free alignments, the MPI version supports insertion–deletion models like the sequential AliSim.

Availability and implementation
AliSim-HPC is open-source and available as part of the new IQ-TREE version v2.2.3 at https://github.com/iqtree/iqtree2/releases with a user manual at http://www.iqtree.org/doc/AliSim.
Exploring water-borne corticosterone collection as a non-invasive tool in amphibian conservation physiology: benefits, limitations and future perspectives

Published: September 2023

Abstract
Global change exposes wildlife to a variety of environmental stressors and is affecting biodiversity worldwide, with amphibian population declines being at the forefront of the global biodiversity crisis. The use of non-invasive methods to determine the physiological state in response to environmental stressors is therefore an important advance in the field of conservation physiology. The glucocorticoid hormone corticosterone (CORT) is one useful biomarker to assess physiological stress in amphibians, and sampling water-borne (WB) CORT is a novel, non-invasive collection technique. Here, we tested whether WB CORT can serve as a valid proxy of organismal levels of CORT in larvae of the common frog (Rana temporaria). We evaluated the association between tissue and WB CORT levels sampled from the same individuals across ontogenetic stages, ranging from newly hatched larvae to froglets at 10 days after metamorphosis. We also investigated how both tissue and WB CORT change throughout ontogeny. We found that WB CORT is a valid method in pro-metamorphic larvae as values for both methods were highly correlated. In contrast, there was no correlation between tissue and WB CORT in newly hatched, pre-metamorphic larvae, metamorphs or post-metamorphic froglets probably due to ontogenetic changes in respiratory and skin morphology and physiology affecting the transdermal CORT release. Both collection methods consistently revealed a non-linear pattern of ontogenetic change in CORT with a peak at metamorphic climax. Thus, our results indicate that WB CORT sampling is a promising, non-invasive conservation tool for studies on late-stage amphibian larvae. However, we suggest considering that different contexts might affect the reliability of WB CORT and consequently urge future studies to validate this method whenever it is used in new approaches. We conclude proposing some recommendations and perspectives on the use of WB CORT that will aid in broadening its application as a non-invasive tool in amphibian conservation physiology.
Defining a core microbial necrobiome associated with decomposing fungal necromass

Published: September 2023

Abstract
Despite growing interest in fungal necromass decomposition due to its importance in soil carbon retention, whether a consistent group of microorganisms is associated with decomposing necromass remains unresolved. Here, we synthesize knowledge on the composition of the bacterial and fungal communities present on decomposing fungal necromass from a variety of fungal species, geographic locations, habitats, and incubation times. We found that there is a core group of both bacterial and fungal genera (i.e. a core fungal necrobiome), although the specific size of the core depended on definition. Based on a metric that included both microbial frequency and abundance, we demonstrate that the core is taxonomically and functionally diverse, including bacterial copiotrophs and oligotrophs as well as fungal saprotrophs, ectomycorrhizal fungi, and both fungal and animal parasites. We also show that the composition of the core necrobiome is notably dynamic over time, with many core bacterial and fungal genera having specific associations with the early, middle, or late stages of necromass decomposition. While this study establishes the existence of a core fungal necrobiome, we advocate that profiling the composition of fungal necromass decomposer communities in tropical environments and other terrestrial biomes beyond forests is needed to fill key knowledge gaps regarding the global nature of the fungal necrobiome.
