Published: October 2024

AbstractEmbryogenesis entails dramatic shifts in mRNA translation and turnover that reprogram gene expression during cellular proliferation and differentiation. Codon identity modulates mRNA stability during early vertebrate embryogenesis, but how the composition of tRNA pools is matched to translational demand is unknown. By quantitative profiling of tRNA repertoires in zebrafish embryos during the maternal-to-zygotic transition, we show that zygotic tRNA repertoires are established after the onset of gastrulation, succeeding the major wave of zygotic mRNA transcription. Maternal and zygotic tRNA pools are distinct, but their reprogramming does not result in a better match to the codon content of the zygotic transcriptome. Instead, we find that an increase in global translation at gastrulation sensitizes decoding rates to tRNA supply, thus destabilizing maternal mRNAs enriched in slowly translated codons. Translational activation and zygotic tRNA expression temporally coincide with an increase of TORC1 activity at gastrulation, which phosphorylates and inactivates the RNA polymerase III repressor Maf1a/b. Our data indicate that a switch in global translation, rather than tRNA reprogramming, determines the onset of codon-dependent maternal mRNA decay during zebrafish embryogenesis.

Authors: Hein Machado Sofia , Sweeney Alex , Hernandez Arturo E , Bunta Ferenc 
Published: October 2024

Purpose:
The purpose of this study was to investigate how the amount of home language use between the primary caregiver and bilingual Spanish- and English-speaking children with hearing loss who use cochlear implants (CIs) versus their bilingual age-matched peers with normal hearing (NH) can impact speech outcomes in the home language.

Method:
Thirty-four bilingual Spanish- and English-speaking children (17 CI users and 17 with NH) between the ages of 5;3 and 7;9 (years;months) participated in this study. Independent variables were the amount of home language use with the primary caregiver and hearing status, and dependent variables were vowels and consonants correctly produced and occurrence of selected phonological processes. The amount of home language use was ascertained from surveys, and the dependent measures were based on a single-word picture elicitation task.

Results:

Bilingual children with CIs who are exposed to Spanish for more than 80% of the time via their primary caregiver performed better on Spanish segmental accuracy measures than those who are exposed to Spanish from only 20% to 50% of the time, specifically on vowels (partial η
2
= .31) and consonants (partial η
2
= .025). Children with NH outperformed children with CIs on all accuracy measures in Spanish.

Conclusions:
Preliminary results suggest the importance of language exposure through interactions with the primary caregiver for speech development in bilingual children. Future studies should investigate strategies to facilitate home language development in bilingual children with CIs, enabling them to reach their full potential.

Published: October 2024

Purpose:
This study is part of a larger study that explores the beliefs and attitudes of Haitian parents in the United States regarding heritage language maintenance. The study sought to understand Haitian parents' perspective of heritage language maintenance when the parent has a child with a communication disorder.

Method:
Semistructured interviews were conducted with seven Haitian parents of children who have or had a speech-language disorder. The interviews were conducted virtually through videoconferencing. A thematic analysis was used to explore the data and determine recurring themes.

Results:
Participants desired to preserve the heritage language; however, fear of further language delay and sociolinguistic factors influenced their language choice. Furthermore, the results revealed that the lack of Haitian Creole language maintenance led to a communication breakdown with family and parental regret on the missed opportunity to pass on the heritage language.

Conclusion:
The findings from this study demonstrate a need for continued education with physicians, SLPs, and other related service providers on the issues related to bilingual language development, language maintenance, and counseling families regarding home language practice.

Survey on coherent multiband splicing techniques for wideband channel characterization
Authors: Dimce Sigrid , Dressler Falko 
Published: October 2024

AbstractCoherent multi‐band splicing is an optimal solution for extending existing band‐limited communication systems to support high‐precision sensing applications. Conceptually, the communication system performs narrow‐band measurements at different centre frequencies, which are then concatenated to increase the effective bandwidth without altering the sampling rate. This can be done in parallel for multiple non‐contiguous subbands or by hopping across the different bands. However, multi‐band splicing poses significant challenges, particularly in compensating for phase offsets and hardware distortions before stitching the acquired samples, which can be distributed in contiguous or non‐contiguous manners. This survey paper studies the state of the art in coherent multi‐band splicing and identify open research questions. For beginners in the field, this review serves as a guide to the most relevant literature, enabling them to quickly catch up with the current achievements. For experts, open research questions that require further investigation are highlighted.
An evolutionary algorithm‐based classification method for high‐dimensional imbalanced mixed data with missing information
Authors: Liu Yi , Li Gengsong , Zheng Qibin , Yang Guoli , Liu Kun , Qin Wei 
Published: October 2024

AbstractThe data scale keeps growing by leaps and the majority of it is high‐dimensional imbalanced data, which is hard to classify. Data missing often happens in software which further aggravates the difficulty of classifying the data. In order to resolve high‐dimensional imbalanced mixed‐variables missing data classification problem, a novel method based on particle swarm optimization is developed. It has three original components including multiple feature selection, mixed attribute imputation, and quantum oversampling. Multiple feature selection uses a two‐stage strategy to obtain stable relevant features. Mixed attribute imputation separates features into continuous and discrete features and fills missing values with different models. Quantum oversampling chooses instances to balance data based on the quantum operator. Furthermore, particle swarm optimization is employed to optimize the parameters of the components to obtain preferable classification results. Six representative classification datasets, six typical algorithms, and four measures are taken to conduct exhaust experiments, and results indicate that the proposed method is superior to the comparison algorithms.

Published: October 2024

AbstractThe application of medical image segmentation technology enables accurate localization of human tissues, providing doctors with a reliable foundation for diagnosis. While deep learning methods have proven effective in this task, most current approaches rely on a single prediction framework, which overlooks Edge semantic features and results in flawed texture features. Moreover, existing supervised methods face challenges due to limited availability of high‐quality annotations in the field of medical imaging. In this article, a Semi‐supervised Contextual Cognitive Augmentation‐based Cross‐teaching Network is proposed. A Contextual Cognitive Enhancement Module is introduced consisting of two components: data augmentation and information extraction. The data augmentation component provides multi‐level data distribution by incorporating diverse perturbation strategies such as Discrete Cosine Transform and Gaussian noise. The information extraction component employs the Comprehensive Information Extraction module, which consists of Global Perception Information Extraction module and Multi‐channel Information Extraction module to extract perceptual information from images and enhance interaction between image channels, respectively. Additionally, a cross‐teaching strategy is adopted and a hybrid loss function is utilized to encourage knowledge sharing among the networks, leveraging the advantages of dual networks for improved performance. Experimental results demonstrate significant enhancements in multiclass medical image segmentation compared to several state‐of‐the‐art single‐framework networks.

The Value of lncRNAs as a Biomarker for the Diagnosis of Gestational
Diabetes: A Meta-Analysis
Authors: Fan Yang , Chen Xin , Yang Song , Tu Hongxia , Zhang Youyi , Wang Mingyi , Jiang Jingying 
Published: October 2024

AbstractGestational diabetes mellitus (GDM) is a common metabolic disorder in pregnancy
and leads to serious harm to the mother and the fetus. A variety of lncRNAs play
a key role in GDM. This meta-analysis was performed to explore the potential
value of lncRNAs in GDM diagnosis. Articles correlated with lncRNA and GDM were
screened from Embase, Medline, EBSCO, PubMed, Chinese National Knowledge
Infrastructure, and WanFang databases. Summary receiver operator characteristic
(SROC) was performed to evaluate the pooled area under curve (AUC). Forest plot
was conducted to calculate the sensitivity, specificity, diagnostic likelihood
ratio (LR), diagnostic score, and diagnostic odds ratio (DOR). Deeks’ funnel
plot was utilized to evaluate the publication bias. Eleven articles containing
12 tests (1060 GDM patients and 1066 controls) were included in this
meta-analysis. AUC (0.89, 95%CI=0.86–0.92), sensitivity (0.84, 95%CI=0.80–0.87),
and specificity (0.81, 95%CI=0.77–0.85)of the SROC curve showed a high
diagnostic value of lncRNA for GDM. Positive LR (PLR 4.40, 95%CI=3.45–5.60) and
negative LR (NLR 0.20, 95%CI=0.15–0.26) results indicated that the diagnosis of
lncRNA for GDM had low clinical utility. Diagnostic score (3.09,
95%CI=2.62–3.57) and DOR (22.04, 95%CI=13.68–35.51) results suggested lncRNAs
have good discriminative effect on GDM. Heterogeneity was significantly higher,
but not induced by the subgroups. LncRNAs had high diagnostic value and good
discriminative effect for GDM, but the clinical utility was not high. This
meta-analysis study offers a potential target for GDM diagnosis.
Deflection of light by wormholes and its shadow due to dark matter within modified symmetric teleparallel gravity formalism
Authors: Mustafa G , Hassan Zinnat , Sahoo P K 
Published: October 2024

Abstract
We explore the possibility of traversable wormhole formation in the dark matter halos in the context of f(Q) gravity. We obtain the exact wormhole solutions with anisotropic matter source based on the Bose–Einstein condensate, Navarro-Frenk-White, and pseudo-isothermal matter density profiles. Notably, we present a novel wormhole solution supported by these dark matters using the expressions for the density profile and rotational velocity along with the modified field equations to calculate the redshift and shape functions of the wormholes. With a particular set of parameters, we demonstrate that our proposed wormhole solutions fulfill the flare-out condition against an asymptotic background. Additionally, we examine the energy conditions (ECs), focusing on the null ECs at the wormhole’s throat, providing a graphical representation of the feasible and negative regions. Our study also examines the wormhole’s shadow in the presence of various dark matter models, revealing that higher central densities result in a shadow closer to the throat, whereas lower values have the opposite effect. Moreover, we explore the deflection of light when it encounters these wormholes, particularly noting that light deflection approaches infinity at the throat, where the gravitational field is extremely strong.
Aspect ratio optimization of piezoelectric extensional mode resonators for quality factor and phase noise performance enhancement
Authors: Tang Ken-Wei , Lin Wei , Zope Anurag A , Lin Zhong-Wei , Li Sheng-Shian 
Published: October 2024

Abstract
This study focuses on optimizing the resonator geometry via the aspect ratio design of a width-extensional mode resonator to improve its quality factor (Q), which is one of the critical performance parameters for resonators in either sensing (Allan deviation) or frequency reference (phase noise) applications. The proposed approach uses finite element analysis to reduce the strain energy at anchor supports by altering the resonator geometric structure, thereby reducing energy loss through anchors. Moreover, process limitations on feature sizes are used as constraints to find aspect ratios that can not only increase the Q but also reduce spurious modes near the targeted frequency. The devices were fabricated using AlN thin film piezoelectric on a substrate (TPoS) process. The simulated energy dissipation trends for specific length-to-width (L/W) ratios closely match the measured changes in the resonator Q values in vacuum. In vacuum, the highest Q-factor achieved by the device is close to 8816, with a motional resistance of a few tens of ohms. Additionally, a board-level oscillator realized using a commercial low-noise amplifier exhibits phase noise performance of −141.21 dBc Hz−1 and −164.25 dBc Hz−1 at 1 kHz and 1 MHz frequency offsets, respectively. The calculated figures of merit for these offsets are 204 and 168, respectively.

Abstract
The three-body dissociation dynamics of the dicationic camphor molecule (C10H16O2+) resulting from Auger decay are investigated using soft x-ray synchrotron radiation. A photoelectron-photoion-photoion coincidence method, a combination of a velocity map imaging spectrometer and a time-of-flight spectrometer is employed to measure the 3D momenta of ions detected in coincidence. The ion mass spectra and the ion–ion coincidence map at photon energies of 287.9 eV (below the C 1s ionization potential) and 292.4 eV (above the C 1s ionization potential for skeletal carbon) reveal that fragmentation depends on the final dicationic state rather than the initial excitation. Using the native frame method, three new fragmentation channels are discussed; (1) CH2CO+ + C7H

Impact of thickness and saturation direction over magnetostatic mode energies and profiles in Ni80Fe20 antidots
Authors: Chiroli S , Faurie D , Adeyeye A O , Zighem F 
Published: October 2024

Abstract
The magnetization dynamics of square arrays of circular antidots fabricated on Si(001) substrates using deep ultraviolet lithography with a 248 nm exposing wavelength have been studied. The effects of thickness (40 nm and 80 nm) and the in-plane direction of the applied magnetic field on the magnetostatic mode energies were investigated through ferromagnetic resonance experiments and micromagnetic simulations for both thicknesses. The experimental results and the simulations allowed the determination of nature of the magnetostatic modes nature measured at angles of 0° and 45° between the applied magnetic field and the axis of the square array. Notably, in this geometry, the main modes do not disapear when the sample is rotated; instead, the localization of the modes follow the rotation of the applied field, with a variation in measured intensity directly related to the surface area occupied by the localized mode.
Ultrafast structural transition and electron-phonon/phonon–phonon coupling in antimony revealed by nonadiabatic molecular dynamics
Authors: Niu Meng , Qin Shun-Yao , Wang Bai-Qian , Chen Nian-Ke , Li Xian-Bin 
Published: October 2024

Abstract
Real-time time-dependent density-functional theory molecular dynamics (rt-TDDFT-MD) reveals the nonadiabatic dynamics of the ultrafast photoinduced structural transition in a typical phase-change material antimony (Sb) with Peierls distortion (PD). As the excitation intensity increases from 3.54% to 5.00%, three distinct structural transition behaviors within 1 ps are observed: no PD flipping, nonvolatile-like PD flipping, and nonstop back-and-forward PD flipping. Analyses on electron-phonon and phonon–phonon couplings indicate that the excitation-activated coherent A1g phonon mode by electron-phonon coupling drives the structural transition within several hundred femtoseconds. Then, the energy of coherent motions are transformed into that of random thermal motions via phonon–phonon coupling, which prevents the A1g-mode-like coherent structure oscillations. The electron-phonon coupling and coherent motions will be enhanced with increasing the excitation intensity. Therefore, a moderate excitation intensity that can balance the coherent and decoherent thermal movements will result in a nonvolatile-like PD flipping. These findings illustrate important roles of nonadiabatic electron-phonon/phonon–phonon couplings in the ultrafast laser-induced structural transitions in materials with PD, offering insights for manipulating their structures and properties by light.
Analysis of an Accurate Iterative Technique with Attenuation Compensation in Planar Laser Induced Fluorescence
Authors: Cholemari Murali R , Vishnubhatla Sri Hari 
Published: October 2024

Abstract
Iterative techniques in Planar Laser Induced Fluorescence (PLIF) evaluations are theoretically analysed. Correction for laser light attenuation is also incorporated in the analysis. Conditions for the convergence of the results and the scalings for the errors are derived. The results are validated against experiments. It is shown that the optimal strategy for implementation of iterative PLIF evaluation with attenuation correction is on the ensemble mean of the fluorescence field. Compared to the implementation with instantaneous fluorescence images, this approach is not only far more efficient computationally, but also is assured to converge monotonically and extremely rapidly, with minimal errors. This is suggested to be a viable and useful technique for PLIF in general, but especially for cases where a reference cell is unfeasible for explicit attenuation correction.

Abstract
Understanding the transport mechanisms that regulate the H-mode pedestal structure is crucial for developing regimes with edge dynamics that are compatible with the thermal and particle load constraints of plasma facing components. In this regard, at the JET tokamak, H-mode plasma regimes featuring small-ELM (BSE) dynamics have been developed, expelling less plasma energy per ELM compared to the standard type-I ELM. The pedestal of these new regimes remains stable against peeling-ballooning modes, leaving its structure unexplained. In this study, three baseline H-mode JET discharges—a reference with type-I ELM and two BSE regimes—are selected to investigate the turbulent transport mechanisms occurring in pedestals with different structures. The turbulence analysis is conducted using local gyrokinetic simulations around the pedestal top position. The results show that at ion scales, while hybrid ITG-KBM and KBM are destabilized in the type-I ELM discharge, the BSE regimes are dominated by hybrid ITG-TEM, suggesting a different role of turbulent transport in the two cases. At electron scales, both regimes are dominated by toroidal and slab ETG, the latter extending up to very small scales. Simulations of turbulence driven by hybrid ITG-TEM focuses on the impact and competition of electromagnetic (EM) effects and equilibrium
