Enhancing Early Identification of Speech-Language-Hearing Delays Through Interprofessional Peer Teaching in a Communication Sciences and Disorders Graduate Training Program
Authors: Lopez Leslie C. , Guidry Megan 
Published: May 2024

Introduction:
In the current health care landscape, a paradigm shift toward team-based care is underway. Integrating interprofessional education experiences into graduate communication sciences and disorders (CSD) programs is essential to cultivate collaborative skills and prepare future professionals for the interprofessional demands of the field. Within this context, peer teaching has emerged as a noteworthy strategy to promote learning. This study aims to contribute to this evolving field by reporting the impact of an interprofessional (speech-language pathology and audiology) peer teaching educational intervention on physician assistant (PA) students' knowledge of speech-language-hearing developmental milestones and developmental screening.

Method:
A quantitative, descriptive methodology with a pretest, posttest interventional design was utilized to assess the impact of a CSD peer-led educational intervention on the knowledge of 35 PA students. The perceived satisfaction of the PA students with the peer-led educational experience was also evaluated.

Results:
Data analysis revealed a significant increase on knowledge posttest scores compared to pretest scores. PA students also reported an overall positive peer learning experience.

Conclusion:
The collaboration between speech-language pathology, audiology, and PA students through peer teaching holds significant importance in the context of pediatric primary care, and for CSD graduate trainings programs interested in improving educational experiences that tailor to interprofessional learning and practice.
Perception of Voicing and Aspiration in Hindi, American English, and Tamil Listeners in Quiet and in Background Noise
Authors: Antony Reethee , Martin Brett , Shafer Valerie , Behrens Susan 
Published: May 2024

Purpose:
There is a dearth of literature in determining whether language groups for whom aspiration and/or voicing is phonologically contrastive show better perception relative to those who do not use these features contrastively and whether the cue type modulates perception in noise. This study addresses perception of laryngeal cues (voicing and aspiration) by Hindi, English, and Tamil listeners, in quiet and in noise.

Method:

Sixteen participants between 20 and 45 years of age were included in each of the three language groups. The stimuli were bilabial stops that contrasted phonetically in voicing and aspiration, voicing-lead [ba], short-lag [pa], and long-lag aspirated [pha], with one set corresponding to the Hindi phonemes /ba/, /pa/, and /p
h
a/ and the second set to the English phonemes /ba/ and /pa/ (which are phonetically [pa] and [pha], respectively). Tamil includes only the short-lag [pa] as a bilabial stop consonant. The stimuli were presented at 70 dB SPL, in quiet and in speech-shaped noise at a signal-to-noise ratio of 0. Participants performed two speech identification tasks and a speech discrimination task.

Results:

Patterns of perceptual assimilation related to the first language were observed in all three language groups, and accuracy was generally higher in quiet than in noise. Hindi participants identified the English /pa/ as Hindi /p
h
a/ and English /ba/ as Hindi /pa/. The American English participants identified Hindi /p
h
a/ as English /pa/ and both the Hindi /pa/ and Hindi /ba/ as English /ba/. In contrast, Tamil listeners generally perceived both Hindi and English bilabial stops as one category, regardless of voicing and aspiration. English and Hindi participants generally showed higher accuracy for native language stimuli. Patterns of assimilation in quiet and noise differed across language groups for each stimulus type. The aspirated stimuli were most likely to be misperceived in noise by all groups (often as /ha/).

Conclusions:
The results serve as evidence that listeners accurately access native language speech cues, even in noise. The results contribute toward a better understanding of cross-linguistic speech processing in noise.

AbstractLinear discriminant analysis is a classical method for solving problems of dimensional reduction and pattern classification. Although it has been extensively developed, however, it still suffers from various common problems, such as the Small Sample Size (SSS) and the multimodal problem. Neighbourhood linear discriminant analysis (nLDA) was recently proposed to solve the problem of multimodal class caused by the contravention of independently and identically distributed samples. However, due to the existence of many small‐scale practical applications, nLDA still has to face the SSS problem, which leads to instability and poor generalisation caused by the singularity of the within‐neighbourhood scatter matrix. The authors exploit the eigenspectrum regularisation techniques to circumvent the singularity of the within‐neighbourhood scatter matrix of nLDA, which is called Eigenspectrum Regularisation Reverse Neighbourhood Discriminative Learning (ERRNDL). The algorithm of nLDA is reformulated as a framework by searching two projection matrices. Three eigenspectrum regularisation models are introduced to our framework to evaluate the performance. Experiments are conducted on the University of California, Irvine machine learning repository and six image classification datasets. The proposed ERRNDL‐based methods achieve considerable performance.

Published: May 2024

ZusammenfassungEine 21-jährige Patientin stellte sich mit seit 2 Wochen bestehendem Fieber, Pharyngitis, Lymphadenopathie und generalisiertem Exanthem vor. Allergien seien nicht bekannt, die Familien- und Reiseanamnese ist unauffällig. Aufgrund einer Depression wird seit 1,5 Jahren Duloxetin eingenommen, bei bipolarer Störung wurde seit 4 Wochen Lamotrigin eingenommen, bei ansteigenden Transaminasen jedoch abgesetzt. Laborchemisch zeigten sich bei Aufnahme eine Eosinophilie (1,327 /nl), eine Lymphozytose sowie das Bild einer akuten Hepatitis (GOT 428 U/l, GPT 438 U/l) mit eingeschränkter Spontangerinnung. Die Entzündungsparameter waren erhöht. Sonografisch imponierte eine Hepatosplenomegalie mit Aszites. Eine akute virale oder parasitäre Infektion wurde serologisch ausgeschlossen. Im Hautbiopsat zeigte sich ein perivaskuläres Entzündungsinfiltrat, passend zu einem Hypersensitivitätssyndrom. Im Leberbiopsat fanden sich entzündliche Infiltrate, vereinbar mit einer medikamentös-toxisch induzierten Hepatitis. Im Verlauf traten Husten, Dyspnoe und ein Pleuraerguss rechts auf. In Zusammenschau der Befunde und mit Hilfe des RegiSCAR-Scores konnte die Diagnose „drug reaction with eosinophilia and systemic symptoms“ (DRESS) gestellt werden. Unter hochdosierter Prednisolontherapie kam es zu einem sukzessiven Abfall der Transaminasen und zur Rekonstitution der Lebersynthese.Bei Eosinophilie, Lymphadenopathie, akuter Hepatitis und generalisiertem Exanthem stellt DRESS eine seltene, aufgrund des potenziell lebensbedrohlichen Verlaufes jedoch wichtige Differenzialdiagnose dar. Die wichtigste Maßnahme ist das sofortige Absetzen der als Auslöser vermuteten Medikation. In schweren Fällen sollte die Therapie mit hochdosierten systemischen Kortikosteroiden erfolgen.

ResumoO cotovelo flutuante é um quadro complexo e raro, causado por trauma de alta energia. Neste artigo, apresentamos o caso de um paciente que sofreu um acidente de trânsito com trauma craniano grave, cotovelo flutuante (fratura diafisária do úmero, fratura diafisária proximal do rádio e fratura segmentar da ulna) e lesão no nervo radial. Foram realizadas fixações com uma placa umeral e hastes intramedulares no antebraço. Embora o resultado tenha sido satisfatório, a sinostose radioulnar foi identificada nos controles pós-operatórios. Devido ao comprometimento neurológico, ao tipo de fraturas e à estabilização selecionada, acreditamos que o uso de hastes intramedulares no antebraço para casos semelhantes deve ser cuidadosamente avaliado.

Published: May 2024

AbstractSolid pseudopapillary tumor is a mixed solid and cystic neoplasm of the pancreas which occurs most commonly in females in second or third decade of life with few reported pediatric cases. It has a low malignancy potential with good prognosis after surgical resection.We present a case of an 11-year-old male child with solid pseudopapillary tumor of pancreas who presented with clinical features of acute pancreatitis. He was initially evaluated with ultrasound, followed by computed tomography (CT) and magnetic resonance imaging (MRI).Solid pseudopapillary tumor of pancreas presenting as acute pancreatitis is rarely reported in literature. This case is a unique presentation of a pancreatic tumor and highlights the value of multiphase CT imaging and MRI in the diagnosis.

The efficient conversion of solar energy to chemical energy represents a critical bottleneck to the energy transition. Photocatalytic splitting of water to generate solar fuels is a promising solution. Semiconductor quantum dots (QDs) are prime candidates for light-harvesting components of photocatalytic heterostructures, given their size-dependent photophysical properties and band-edge energies. A promising series of heterostructured photocatalysts interface QDs with transition-metal oxides which embed midgap electronic states derived from the stereochemically active electron lone pairs of p-block cations. Here, we examine the thermodynamic driving forces and dynamics of charge separation in Sb2VO5/CdSe QD heterostructures, wherein a high density of Sb 5s2-derived midgap states are prospective acceptors for photogenerated holes. Hard-x-ray valence band photoemission spectroscopy measurements of Sb2VO5/CdSe QD heterostructures were used to deduce thermodynamic driving forces for charge separation. Interfacial charge transfer dynamics in the heterostructures were examined as a function of the mode of interfacial connectivity, contrasting heterostructures with direct interfaces assembled by successive ion layer adsorption and reaction (SILAR) and interfaces comprising molecular bridges assembled by linker-assisted assembly (LAA). Transient absorption spectroscopy measurements indicate ultrafast (&lt;2 ps) electron and hole transfer in SILAR-derived heterostructures, whereas LAA-derived heterostructures show orders of magnitude differentials in the kinetics of hole (&lt;100 ps) and electron (∼1 ns) transfer. The interface-modulated kinetic differentials in electron and hole transfer rates underpin the more effective charge separation, reduced charge recombination, and greater photocatalytic efficiency observed for the LAA-derived Sb2VO5/CdSe QD heterostructures.

Novel magnetic materials with non-trivial magnetic structures have led to exotic magnetic transport properties and significantly promoted the development of spintronics in recent years. Among them is the Cr

family, the magnetism of which can persist above room temperature, thus providing an ideal system for potential spintronic applications. Here we report the synthesis of a new compound, Cr0.82Te, which demonstrates a record-high topological Hall effect at room temperature in this family. Cr0.82Te displays soft ferromagnetism below the Curie temperature of 340 K. The magnetic measurement shows an obvious magneto-crystalline anisotropy with the easy axis located in the ab plane. The anomalous Hall effect can be well explained by a dominating skew scattering mechanism. Intriguing, after removing the normal Hall effect and anomalous Hall effect, a topological Hall effect can be observed up to 300 K and reaches up to 1.14 μΩ⋅cm at 10 K, which is superior to most topological magnetic structural materials. This giant topological Hall effect possibly originates from the noncoplanar spin configuration during the spin flop process. Our work extends a new Cr

Ameliorated in vitro anti-cancer efficacy of methotrexate loaded zinc oxide nanoparticles in breast cancer cell lines MCF-7 & MDA-MB-231 and its acute toxicity study
Authors: Joshi Mitesh , Bhatt Purvi 
Published: May 2024

Abstract
Traditional therapies often struggle with specificity and resistance in case of cancer treatments. It is therefore important to investigate new approaches for cancer treatment based on nanotechnology. Zinc oxide nanoparticles (ZnONPs) are known to exhibit anti-cancer properties by inducing oxidative stress, apoptosis, and cell cycle arrest. Methotrexate (MTX) a known anti-folate shows specificity to folate receptors and interrupts healthy functioning of cells. This study proposes the use of previously characterized biocompatible Methotrexate loaded Zinc oxide nanoparticles (MTX-ZnONPs) as a dual action therapeutic strategy against breast cancer cell lines, MCF-7 (MTX-sensitive) and MDA-MB-231 (MTX-resistant). To elucidate the cytotoxicity mechanism of MTX-ZnONPs an in depth In vitro study was carried out. In vitro assays, including cell cycle analysis, apoptosis assay, and western blot analysis to study the protein expression were performed. Results of these assays, further supported the anti-cancer activity of MTX-ZnONPs showing apoptotic and necrotic activity in MCF-7 and MDA-MB-231 cell line respectively. In vivo acute oral toxicity study to identify the LD50 in animals revealed no signs of toxicity and mortality up to 550 mg kg−1 body weight of animal, significantly higher LD50 values than anticipated therapeutic levels and safety of the synthesized nanosystem. The study concludes that MTX-ZnONPs exhibit anti-cancer potential against breast cancer cells offering a promising strategy for overcoming resistance.

Published: May 2024

Abstract

Objective. Intra-esophageal pressure (Pes) measurement is the recommended gold standard to quantify respiratory effort during sleep, but used to limited extent in clinical practice due to multiple practical drawbacks. Respiratory inductance plethysmography belts (RIP) in conjunction with oronasal airflow are the accepted substitute in polysomnographic systems (PSG) thanks to a better usability, although they are partial views on tidal volume and flow rather than true respiratory effort and are often used without calibration. In their place, the pressure variations measured non-invasively at the suprasternal notch (SSP) may provide a better measure of effort. However, this type of sensor has been validated only for respiratory events in the context of obstructive sleep apnea syndrome (OSA). We aim to provide an extensive verification of the suprasternal pressure signal against RIP belts and Pes, covering both normal breathing and respiratory events. Approach. We simultaneously acquired suprasternal (207) and esophageal pressure (20) signals along with RIP belts during a clinical PSG of 207 participants. In each signal, we detected breaths with a custom algorithm, and evaluated the SSP in terms of detection quality, breathing rate estimation, and similarity of breathing patterns against RIP and Pes. Additionally, we examined how the SSP signal may diverge from RIP and Pes in presence of respiratory events scored by a sleep technician. Main results. The SSP signal proved to be a reliable substitute for both esophageal pressure (Pes) and respiratory inductance plethysmography (RIP) in terms of breath detection, with sensitivity and positive predictive value exceeding 75%, and low error in breathing rate estimation. The SSP was also consistent with Pes (correlation of 0.72, similarity 80.8%) in patterns of increasing pressure amplitude that are common in OSA. Significance. This work provides a quantitative analysis of suprasternal pressure sensors for respiratory effort measurements.
Study on copper-to-copper bonding of three-dimensional integrated circuits using the quasicontinuum method
Authors: Nguyen Hoang-Giang , Wu Miao-Jing , Fang Te-Hua 
Published: May 2024

Abstract
Cu-Cu bonding presents an attractive approach to bottom-up manufacturing, facilitating nanoparticle production, linking, and restoration. The ramifications of varying bonding depths and orientations exhibit distinct characteristics. At the same time, investigations into the material composition of nanoscale bonded pairs involve scrutiny of atomic slippage, strain distribution, and the force-displacement profile. The methodology simulates the Cu-Cu bonding process by implementing the quasi-continuum (QC) approach, constituting a multifaceted mixed molecular dynamics technique integrating atomistic and continuum methods. The analysis of results reveals variations in the Contact effect induced by the four orientations, along with discrepancies in the atomic slippage observed in distinct directions. Notably, a pronounced distinction is discernible in the directional movement. Specifically, the strained regions on the flat surface of the lower substrate, characterized by the directionality of X[001]-Y[110], exhibit a notably broader range of atomic slip compared to regions strained by alternative orientations. Furthermore, the directional alignment of X[110]-Y[111] illustrates that irrespective of whether the lower substrate’s surface is flat or rough, the orientation of atomic slip diverges. In conclusion, our study employed a quasi-continuous method to explore the bonding efficacy of copper-to-copper interfaces on flat and irregular substrate surfaces. Through this approach, we scrutinized the distributions of strain, stress, average Newtonian force, and atom differential arrangement direction across different orientations.

Published: May 2024

Abstract
Multiferroics with strong magnetoelectric coupling can be created by improving the magnetostriction of the ferrite phase and combining it with the best-known piezoelectric. Herein, the ferromagnetic CoFe2O4 was modified with Al incorporation further improve the resistivity, magnetic, and magnetostrictive properties and then combined with (0.5)Ba(Zr0.2Ti0.8)O3−(0.5)(Ba0.7Ca0.3)TiO3 (BCZT) with different weight percentages. XRD results revealed the presence of a mixed spinel cubic phase for CAF (Fd-3m), whereas BCZT crystallized in a tetragonal structure (Amm2) in composite systems. The dielectric response of the materials was studied using impedance spectroscopy and it displayed a typical Maxwell–Wagner polarization of two-phase composites. The magnetic response of the CAF sample improved significantly which is attributed to the preference of Al3+ ions on tetrahedral sites. The magnetization of composites increased as the nonmagnetic BCZT component increased and the (0.75)CAF-(0.25)BCZT system had the highest saturation magnetization. We anticipate that these systems will have significantly improved magnetoelectric characteristics than unmodified CFO-BCZT systems.

Published: May 2024

Abstract
In this study, an examination of the Yu-Toda-Sasa-Fukuyama equation is undertaken, a model that characterizes elastic waves in a lattice or interfacial waves in a two layer liquid. Our emphasis lies in conducting a comprehensive analysis of this equation through various viewpoints, including the examination of soliton dynamics, exploration of bifurcation patterns, investigation of chaotic phenomena, and a thorough evaluation of the model’s sensitivity. Utilizing a simplified version of Hirota’s approach, multi-soliton pattens, including 1-wave, 2-wave, and 3-wave solitons, are successfully derived. The identified solutions are depicted visually via 3D, 2D, and contour plots using Mathematica software. The dynamic behavior of the discussed equation is explored through the theory of bifurcation and chaos, with phase diagrams of bifurcation observed at the fixed points of a planar system. Introducing a perturbed force to the dynamical system, periodic, quasi-periodic and chaotic patterns are identified using the RK4 method. The chaotic nature of perturbed system is discussed through Lyapunov exponent analysis. Sensitivity and multistability analysis are conducted, considering various initial conditions. The results acquired emphasize the efficacy of the methodologies used in evaluating solitons and phase plots across a broader spectrum of nonlinear models.
