AbstractUnderstanding development and genetic regulation in theAnopheles gambiaegermline is essential to engineer effective genetic control strategies targeting this malaria mosquito vector. These include targeting the germline to induce sterility or using regulatory sequences to drive transgene expression for applications such as gene drive. However, only very few germline-specific regulatory elements have been characterised with the majority showing leaky expression. This has been shown to considerably reduce the efficiency of current genetic control strategies, which rely on regulatory elements with more tightly restricted spatial and/or temporal expression. Meiotic silencing of the sex chromosomes limits the flexibility of transgene expression to develop effective sex-linked genetic control strategies. Here, we build on our previous study, dissecting gametogenesis into four distinct cell populations, using single-cell RNA sequencing to define eight distinct cell clusters and associated germline cell–types using available marker genes. We reveal overexpression of X-linked genes in a distinct cluster of pre-meiotic cells and document the onset of meiotic silencing of the X chromosome in a subcluster of cells in the latter stages of spermatogenesis. This study provides a comprehensive dataset, characterising the expression of distinct cell types through spermatogenesis and widening the toolkit for genetic control of malaria mosquitoes.
Imaging Fermi-level hysteresis in nanoscale bubbles of few-layer MoS2

Published: August 2023

AbstractThe electrical stability and reliability of two-dimensional (2D) crystal-based devices are mainly determined by charge traps in the device defects. Although nanobubble structures as defect sources in 2D materials strongly affect the device performance, the local charge-trapping behaviors in nanobubbles are poorly understood. Here, we report a Fermi-level hysteresis imaging strategy using Kelvin probe force microscopy to study the origins of charge trapping in nanobubbles of MoS2 on SiO2. We observe that the Fermi-level hysteresis is larger in nanobubbles than in flat regions and increases with the height in a nanobubble, in agreement with our oxide trap band model. We also perform the local transfer curve measurements on the nanobubble structures of MoS2 on SiO2, which exhibit enhanced current-hysteresis windows and reliable programming/erasing operations. Our results provide fundamental knowledge on the local charge-trapping mechanism in nanobubbles, and the capability to directly image hysteresis can be powerful tool for the development of 2D material-based memory devices.
A novel artificial intelligence based wireless local area network channel access control scheme for low latency e‐health applications
Authors: Liu Zixin , Lv Yunxin , Bi Meihua , Zhai Yanrong 
Published: August 2023

AbstractTo effectively support low‐latency e‐health applications, a novel artificial intelligence‐based wireless local area network (WLAN) channel access control scheme named intelligent hybrid channel access (IHCA) is proposed and studied. In the IHCA scheme, each beacon interval comprises multiple cycles, with each cycle containing a contention‐free period (CFP) and a contention period (CP). By adopting an artificial neural network (ANN) and utilizing its calculation outputs to (1) decide whether to poll a hub during the CFP and (2) determine the initial backoff count (IBC) of each hub, polling of empty hubs during CFP can be reduced, and collisions during CP can be relieved. The authors’ simulation results show that the IHCA scheme can effectively reduce latency compared to the Hybrid coordination function Controlled Channel Access (HCCA) and the Request based Polling Access (RPA) reference designs.
A novel blind tamper detection and localization scheme for multiple faces in digital images
Authors: Thabit Rasha 
Published: August 2023

AbstractFace image manipulation detection (FIMD) is a research area of great interest, widely applicable in fields requiring data security and authentication. Existing FIMD schemes aim to identify manipulations in digital face images, but they possess individual strengths and limitations. Most schemes can only detect specific manipulations under certain conditions, leading to variable success rates across different images. The literature lacks emphasis on detecting manipulations involving multiple faces. This paper introduces a novel blind tamper detection and localization scheme specifically designed for multiple faces in digital images. The proposed multiple faces manipulation detection (MFMD) scheme consists of two stages: face detection and selection, and image watermarking. Through extensive experiments, the MFMD scheme's performance has been evaluated on various multiple‐face images, considering embedding capacity, payload, watermarked image quality, time complexity, and manipulation detection ability. The results demonstrate the MFMD scheme's efficacy in detecting different types of manipulations for multiple faces in images. Furthermore, the watermarked images exhibit high visual quality, even when multiple faces are present. The scheme's efficiency recommends it for practical applications, especially in sharing personal images over unsecured networks. This research advances FIMD techniques by addressing the neglected area of multiple‐face manipulation detection. With improved accuracy, faster processing times, and resilience against various manipulations, the MFMD scheme offers valuable capabilities for enhancing data security and authentication in real‐world scenarios.

Abstract
Purpose The aim of this guideline was to find evidence on whether carrying out Doppler examinations and CTGs in low-risk cohorts of pregnant women improves outcomes.
Methods First, a systematic search for guidelines was carried out. Identified guidelines were evaluated using the DELPHI instrument of the AWMF. Three guidelines were found to be
suitable to evaluate CTG. Two DEGUM best practice guidelines were judged suitable to describe the methods. All studies on this issue were additionally analyzed using 8 PICO questions. A
structured consensus of the participating professional societies was achieved using a nominal group process and a structured consensus conference moderated by an independent moderator.
Recommendations No antepartum Doppler sonography examinations should be carried out in low-risk cohorts in the context of antenatal care. No antepartum CTG should be carried out in
low-risk cohorts.
Note The guideline will be published simultaneously in the official journals of both professional societies (i.e., Geburtshilfe und Frauenheilkunde for the DGGG and
Ultraschall in der Medizin/European Journal of Ultrasound for the DEGUM).

Published: August 2023

AbstractThe cruise market has significant potential for family travel as birth rates continue to decline. To explore the reasons behind family cruise travel, passenger needs, and the three stages of cruise travel experience (anticipation, participation, and recall), this study employs qualitative research and in-depth survey methods. The study’s findings indicate that motivations for joining family cruise travel include "new experiences," "desire for cruise travel," "convenience," and "generating social topics/publicity." During the anticipation and recall stages, the most significant factors are the "port of call" and the "destination" of the cruise itinerary. Additionally, other important aspects include the dining options on the cruise. In the participation stage, the study reveals that cabins, entertainment, and special considerations for children hold particular significance. These results can provide valuable guidance in the planning of family cruise travel.
Exploring factors influencing pre-service teacher’s digital teaching competence and the mediating effects of data literacy: empirical evidence from China

Published: August 2023

AbstractThe development of pre-service teachers’ digital teaching competence is crucial for effectively infusing technology into teaching. With the growing importance of data in education, it is imperative to explore the influencing factors of digital teaching competence and the potential role of data literacy in facilitating competence. Thus, this study focused on investigating the factors influencing pre-service teachers’ digital teaching competence, namely technology attitudes, technology operations, technology ethics, and data literacy. Additionally, it examined the potential effect of data literacy on digital teaching competence. The study involved 244 Chinese pre-service teachers, and a Structural Equation Model (SEM) was created using SPSS and SmartPLS for analysis. The findings highlighted that technology attitudes, technology ethics, and data literacy directly influenced pre-service teachers’ digital teaching competence. Data literacy fully mediated the relationship between technology operations and digital teaching competence, and partially mediated the relationships between technology attitudes and digital teaching competence, as well as between technology ethics and digital teaching competence. Moreover, technology ethics acted as a partial mediator between technology attitudes and both digital teaching competence and data literacy. These results indicated that fostering positive technology attitudes, technology operations, and technology ethics could enhance pre-service teachers’ data literacy and improve their digital teaching competence.
Robust control design for suspension system in LIGO
Authors: Roy Ashmita , Banavar Ravi N 
Published: August 2023

Abstract
In this article, we present a relatively new state-space methodology, called

synthesis, to design a robust controller for a subsystem of the Laser Interferometer Gravitational Wave Observatory. In particular, we examine the quadruple pendulum subsystem, which is simplified for the purpose of the study to a two wire simple pendulum system. Structured and unstructured uncertainties are considered in the modelling, though the structured ones are incorporated in the unstructured framework based on a design philosophy presented in the literature. Incorporating weighting functions that emphasize the spectral band of the uncertainties as well as the band in which disturbances are to be attenuated, we design a robust control law using the coprime factorization technique of the

paradigm.

. We obtain an analytical expression for the set of maxima of the trajectories, in Cartesian coordinates, without using the Lambert W function. Also, we investigate the effect of parameter k on the radial distance of the projectile showing that the radial distance oscillates from a certain critical launch angle and find an approximate expression for it. In our analysis, we consider the impact of parameter k in the kinetic energy, the potential energy, the total energy, the rate of energy loss, and the phase space. Our results can be included in an intermediate-level classical mechanics course.
Experimental validation and uncertainty analysis of an innovative IoT infrared sensor for in-situ wall thermal transmittance measurement
Authors: Serroni Serena , Arnesano Marco , Martarelli Milena , Revel Gian Marco 
Published: August 2023

Abstract
This paper presents the development and experimental validation of an Internet of Things (IoT) thermography system for in-situ and real-time monitoring of wall thermal transmittance. The solution proposed has been derived from the upgrade of the Comfort Eye sensor, which is an infrared-based sensor adopted for non-intrusive indoor environmental quality monitoring in occupied buildings. In this work, the system has been used to detect potential building envelope inefficiencies and track building performance trends in a continuous way. The methodology is based on the ISO 9869-2 standard but it has been applied to an entire wall and during its normal functioning without the need of operators. The data management has been performed with a dedicated IoT architecture that allows the synchronised collection of quantities required for transmittance calculation, i.e. indoor and outdoor air temperatures together with the thermographic maps of the wall. The measurement technique has been validated in a real building through the comparison with the results obtained using a heat flux meter (HFM). An uncertainty analysis with Monte Carlo simulation has also been performed to evaluate the overall uncertainty of the method. The values obtained are coherent with those measured with the HFM and the infrared system has proved to be able to provide thermal transmittance measurements with an expanded uncertainty of ±0.038 W m−2K−1 with coverage factor k = 2. The innovative methodology described can be used for U-value estimation without the need for extra measuring tools.
A molecular dynamics study of the effects of velocity and diameter on the impact behavior of zinc oxide nanoparticles
Authors: Burlison Scott , Becker Michael F , Kovar Desiderio 
Published: August 2023

Abstract
Molecular dynamics simulations of particle impact have been conducted for a ceramic with mixed ionic-covalent bonding. For these simulations, individual zinc oxide (ZnO) nanoparticles (NPs) were impacted onto a ZnO substrate to observe the effects of impact velocity (1500–3500 m s−1) and particle diameter (10, 20, and 30 nm) on particle deformation and film formation mechanisms that arise during the micro-cold spray process for producing films. The study shows that a critical impact velocity range exists, generally between 1500 and 3000 m s−1, for sticking of the NP to the substrate. Results suggest that solid-state amorphization-induced viscous flow is the primary deformation mechanism present during impact. Decreasing particle diameter and increasing impact velocity results in an increased degree of amorphization and higher local temperatures within the particle. The impact behavior of mixed ionic-covalent bonded ZnO is compared to the behavior of previously studied ionic and covalent materials.
Complex coincidence of superconducting and inverse proximity in quasi 2D nanostructured SnTe
Authors: Singh Satyendra , Saravanan M P , Venkatesh R 
Published: August 2023

Abstract
The induction of superconductivity in topological insulators and topological crystalline insulators is being investigated rigorously as a promising strategy for taking quantum spintronic applications to the next level. In this work, the complex interplay between topological and superconducting components is carefully tuned in such a way that an unusual coincidence of superconducting and inverse proximity is captured for the first time in the electrical transport properties of quasi two-dimensional nanostructured SnTe contacted using ‘s-wave’ superconducting electrodes. Ultralow temperature measurements in the complex superconducting proximity phase reveal two critical fields (H
c2) of 0.9 T and 510 Oe. The lower H
c2 is identified to be from the superconducting electrode while the higher one is attributed to the interface. The presence (absence) of coincidence between the upper critical field (H
C2) extracted from Ginzburg–Landau theory and the Werthamer–Helfand–Hohenberg plot in the normal (inverse) superconducting proximity region and concurrent crossover in correlation lengths ξ(T) and L
φ(T) are observed to be the manifestation of robust competition between the mutual domination of different mechanisms such as topological surface states and Cooper pair correlations. The current-dependent magnetoresistance measurements clearly demonstrate the dominant role of the interplay between the superconducting correlations and spin–orbit coupling. Interestingly, mere doubling of the contact area of the superconductor is observed to simultaneously enhance the critical field to ∼4 T and the transition temperature to ∼4.1 K in the interface region, suggesting the possibility of opening up a new gateway into nano-topological superconducting spintronic applications.
Near-field diffraction of protons by a nanostructured metallic grating under external electric field: asymmetry and sidebands in Talbot self-imaging
Authors: Barman Sushanta , Bhattacharjee Sudeep 
Published: August 2023

Abstract
Self-imaging in near-field diffraction is a practical application of coherent manipulation of matter waves in Talbot interferometry. In this work, near-field diffraction of protons by a nanostructured metallic grating under the influence of (a) uniform, (b) spatially modulated, and (c) temporally modulated electric fields are investigated. Time-domain simulations of two-dimensional Gaussian wave packets for protons are performed by solving the time-dependent Schrödinger’s equation using the generalized finite difference time domain method for quantum systems. Effects of strength (E
0) and orientation (θ) of the uniform electric field on the diffraction properties, such as fringe pattern, intensity of the peaks, fringe shift, and visibility, are investigated. The results show that the Talbot fringes shift significantly in the transverse direction even for a small change in the applied electric field (

This study will be helpful in uniform electric field-controlled precision metrology, developing a highly sensitive electric field sensor based on Talbot interference, and precisely aligning the matter wave optical setup. Furthermore, the sidebands in the Talbot fringe can be used as a precise tool for momentum splitter in matter wave interferometry.
Revisiting the Software-Efficient Stream Ciphers RCR-64 and RCR-32
Authors: Joseph Mabin , Sekar Gautham , Balasubramanian R 
Published: August 2023

Abstract
The synchronous stream ciphers RCR-64 and RCR-32 designed by Sekar, Paul and Preneel are strengthened variants of the ciphers TPy and TPypy (designed by Biham and Seberry), respectively. The RCR ciphers have remained unbroken since they were published in 2007. In this paper, we present arguments that not only support the designers’ security claims but suggest, in general, that the ciphers are secure against several classes of cryptanalytic attacks. We find that the ciphers are best used with 256-bit keys and 384-bit IVs. We also suggest ways to protect software implementations of the RCR ciphers against (cache-)timing and processor flag attacks. Our performance evaluation suggests that the protected implementation of the RCR-64 encrypts long messages at speeds comparable to some of the fastest stream ciphers available today. Consequently, we find that the RCR ciphers may be well suited for PC-based applications in general and streaming audio / video applications in particular. This is the first paper to present a detailed study on the security and performance of the RCR ciphers.

Published: August 2023

Abstract

Background
Vedolizumab, an anti-α4β7 integrin approved for intravenous (IV) treatment of moderately to severely active ulcerative colitis (UC) and Crohn’s disease (CD), was evaluated as a subcutaneous (SC) formulation in maintenance therapy for UC and CD in phase 3 VISIBLE 1, 2, and open-label extension studies, and recently approved in Europe, Australia, and Canada. Our aim was to evaluate efficacy and safety of IV and SC vedolizumab in clinically relevant UC and CD scenarios.

Methods
Post hoc data analyses from VISIBLE trials examined: (1) whether baseline characteristics predict clinical response to 2 vs 3 IV vedolizumab induction doses; (2) efficacy and safety of switching during maintenance vedolizumab IV to SC in patients with UC; (3) vedolizumab SC after treatment interruption of 1–46 weeks; (4) increasing dose frequency of vedolizumab SC from every 2 weeks (Q2W) to every week (QW) after disease worsening.

Results
No baseline characteristics were identified as strong predictors of response to 2 vs 3 vedolizumab infusions. Most patients achieved clinical response after 2 or 3 doses of IV vedolizumab maintained with SC treatment. Clinical remission and response rates were maintained in patients transitioned from maintenance vedolizumab IV to SC treatment. Of patients with UC, ≥75% achieved response following resumption after dose interruption. Escalation to QW dosing resulted in ≥45% of patients regaining response after loss while receiving vedolizumab Q2W.

Conclusions
Clinical real-world scenarios with vedolizumab SC were reviewed using VISIBLE studies data. Vedolizumab SC provides an additional dosing option for patients with UC and CD.
