AI‐generated video steganography based on semantic segmentation
Authors: Lin Yangping , Luo Peng , Zhang Zhuo , Liu Jia , Yang Xiaoyuan 
Published: June 2024

AbstractTraditional video steganography methods primarily rely on modifying concealed spaces for embedding, thereby exhibiting a certain degree of security and embedding capacity. Nevertheless, these methods do not fully capitalize on the rich semantic information inherent in videos, limiting their overall effectiveness. In this paper, an AI‐generated video steganography scheme based on semantic segmentation is proposed. The mapping relationship between secret and semantic information is established by using a semantic segmentation model. The secret information can be converted into semantic labels by semantic histograms or pixels means, and semantic labels containing secret information are obtained and input into the video‐to‐video model to drive the generation of stego videos. After receiving the stego video, the receiver extracts the secret information using a pre‐defined specific embedding mode, including the methods of sub‐block partitioning and embedding capacity per frame. The experimental results show that the stego video has good visual quality, security, and robustness against various noise attacks.

Authors: Zhan Yage , Liu Lirui , Li Kehan 
Published: June 2024

AbstractCoherent Rayleigh scattering‐based distributed fibre optic sensing technology enables real‐time acquisition of vibration and acoustic information along the optical fibres. However, the complexity of monitoring environments often leads to false alarms and missed detections during the process of information source identification with distributed acoustic sensing (DAS). Therefore, it becomes crucial to effectively extract meaningful signal features and perform accurate pattern recognition in the presence of external noise disturbance. The authors provide a comprehensive review of signal feature extraction and pattern recognition techniques applied in DAS technology. After introducing the fundamentals of DAS, specific applications are considered, and the following techniques have been analysed and compared: feature extraction algorithms based on wavelet decomposition, feature extraction schemes utilising other decomposition models, traditional recognition classifiers, and neural network‐based recognition classifiers using deep learning. The advantages and limitations of each scheme are discussed, along with their potential applications in various scenarios. The aim is to provide insights into the latest technologies in signal processing and pattern recognition for DAS, fostering further advancements in this field.
Optimising collection geometry for long‐range synthetic aperture sonar interferometry
Authors: Hansen Roy Edgar , Sæbø Torstein Olsmo 
Published: June 2024

AbstractInterferometric synthetic aperture sonar (SAS) is a technique to image and map the seabed in very high resolution. For large area coverage rate systems with hundreds of metres swath width, the achievable performance varies significantly over the swath. The performance is a function of system, collection geometry, and seabed type. A model is suggested to optimise the collection geometry for maximising area coverage rate given certain optimisation criteria, such as observation geometry, signal‐to‐noise ratio, depth measurement accuracy, and coverage within swath. The model is fitted to measurements (or calibrated) through a simple procedure. Specifically, the effect of vehicle altitude during the interferometric SAS data collection is studied. A novel model on data collected by a HUGIN Superior autonomous underwater vehicle carrying a HISAS 1032 Dual Rx interferometric SAS is demonstrated. The authors show that optimising the collection geometry, and in this case specifically the vehicle altitude, significantly improves the overall performance.

Published: June 2024

AbstractIn the realm of smart city development, the integration of intelligent agents has emerged as a pivotal strategy to enhance the efficacy of search methodologies. This study introduces a novel state‐space navigational model employing intelligent agents tailored specifically for fire surveillance in urban environments. Central to this model is the fusion of a convolutional neural network and multilayer perceptron, enabling accurate fire detection and localisation. Leveraging this capability, the intelligent agent proactively navigates through the search space, guided by the shortest path to the identified fire location. The utilisation of the A* algorithm as the search mechanism underscores the efficiency and efficacy of our proposed approach. Implemented in Python and Gephi, our method surpasses traditional search algorithms, both informed and uninformed, demonstrating its effectiveness in navigating urban landscapes for fire surveillance. This research study contributes significantly to the field by offering a robust solution for proactive fire detection and surveillance in smart city environments, thereby enhancing public safety and urban resilience.
Research on the online monitoring technique for transformer oil level based on ultrasonic sensors

Published: June 2024

AbstractIn order to solve the problem of remote oil level measurement for unmanned transformers, this paper proposes an online monitoring technology for transformer oil level based on ultrasonic sensors. Subsequently, a finite element model and experimental testing platform were constructed to analyse and verify the influencing factors of the transformer oil level sensors. The results indicated that there is a lower measurement error at 140 kHz in the ultrasonic frequency range of 20–320 kHz, which can be selected as the recommended frequency. The impurities in the oil and the thickness of the tank wall have a slight impact on the accuracy of oil level measurement, and can lead to a decrease in the signal‐to‐noise ratio of the echo. Furthermore, as the speed of sound increases by about 4 m/s, for every 1°C increase in oil temperature, it is necessary to calibrate the measurement results based on the oil temperature. The test results of actual experimental transformers showed that the designed online monitoring device can achieve high‐precision monitoring of transformer oil level, with a relative error generally less than 3%.

ResumoA escoliose idiopática do adolescente (EIA) é considerada a deformidade vertebral de maior gravidade e ocorrência, que acomete crianças e adolescentes ainda na fase de desenvolvimento neuropsicomotor, antes de atingirem a maturidade esquelética.Este estudo teve como objetivo avaliar a abordagem cirúrgica da EIA, considerando resultados associados à redução de curvatura patológica, função pulmonar e repercussões na qualidade de vida dos adolescentes submetidos a tal tratamento.Revisão Sistemática de literatura, com abordagem quanti-qualitativa dos dados coletados, cuja estruturação se deu conforme as orientações de Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) realizada nas bases de dados vinculadas à Medical Literature Analysis and Retrieval System Online (MEDLINE) e Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS). A amostra total dos estudos foi de 638 adolescentes com EIA, com uma idade média de 14,93 anos ± 1,24.A correção média da curvatura patológica principal nos estudos foi de 55,06% ± 12,24. Em todos os estudos selecionados com fusão espinhal posterior para correção da EIA verificou-se redução significativa das curvaturas patológicas (> 49%), sendo que a reincidência de curvatura em nenhum dos estudos superou um ganho patológico superior a 5%. Quanto à função pulmonar, os estudos apontaram ganhos significativos de volume expiratório forçado em 1 segundo (VEF1) e capacidade vital forçada (CVF) em pacientes com EIA grave. Além disso, não foram relatados prejuízos de função pulmonar após intervenção cirúrgica para correção da EIA.

Published: June 2024

Resumo
Objetivo A síndrome da dor regional complexa (SDRC) precisa ser mais bem compreendida. Assim, este estudo objetiva analisar se fatores pré e intraoperatórios poderiam estar relacionados ao desenvolvimento de SDRC no pós-operatório.
Métodos Foram revisados 1.183 prontuários de pacientes submetidos a cirurgias no antebraço e na mão entre 2015 e 2021. Os dados de interesse, como diagnóstico, incisões, material de síntese e anestesia realizada, foram coletados, tabulados e submetidos a testes estatísticos com posterior cálculo da razão de chances.
Resultados A maioria dos pacientes era do gênero feminino, com idade entre 30 e 59 anos, que buscaram o serviço de forma eletiva (67% dos casos). Os diagnósticos agrupados de forma geral foram: traumas de partes moles (43%), traumas ósseos (31,6%) e síndromes compressivas (25,5%). Durante esse período, 45 pacientes (3,8%) evoluíram com SDRC. A análise estatística mostrou que a chance de desenvolver SDRC é duas vezes maior em pacientes com síndrome compressiva, especialmente a síndrome do túnel do carpo (STC), que representou a maioria dos cirurgias realizadas em nosso serviço (24%). Em 7,6% dos casos, foram realizadas duas ou mais incisões, o que triplicou a possibilidade de SDRC pós-operatória. Gênero, idade, uso de material de síntese, ou tipo de anestesia não aumentaram estatisticamente o risco de SDRC no pós-operatório.
Conclusão Em suma, a incidência de SDRC é baixa, mas é importante conhecer e reconhecer os fatores de risco para a prevenção e a busca ativa no pós-operatório.

Anti-Müllerian Hormone: A Molecular Key to Unlocking Polycystic Ovary Syndrome?
Authors: Abbott David H. , Hutcherson Beverly A. , Dumesic Daniel A. 
Published: June 2024

AbstractAnti-Müllerian hormone (AMH) is an important component within androgen receptor (AR)-regulated pathways governing the hyperandrogenic origin of polycystic ovary syndrome (PCOS). In women with PCOS, granulosa cell AMH overexpression in developing ovarian follicles contributes to elevated circulating AMH levels beginning at birth and continuing in adolescent daughters of PCOS women. A 6 to 7% incidence among PCOS women of gene variants coding for AMH or its receptor, AMHR2, suggests genetic contributions to AMH-related pathogenesis. Discrete gestational AMH administration to pregnant mice induces hypergonadotropic hyperandrogenic, PCOS-like female offspring with high circulating AMH levels that persist over three generations, suggesting epigenetic contributions to PCOS through developmental programming. Moreover, adult-onset, selective hyperactivation of hypothalamic neurons expressing gonadotropin-releasing hormone (GnRH) induces hypergonadotropic hyperandrogenism and PCOS-like traits in female mice. Both gestational and adult AMH inductions of PCOS-like traits are prevented by GnRH antagonist coadministration, implicating luteinizing hormone–dependent ovarian theca cell testosterone (T) action, mediated through the AR in AMH-induced pathogenesis. Interestingly, gestational or peripubertal exogenous T or dihydrotestosterone induction of PCOS-like traits in female mice, rats, sheep, and monkeys fails to elicit ovarian AMH hypersecretion; thus, AMH excess per se may lead to a distinct pathogenic contribution to hyperandrogenic PCOS origins.
From the past to the present: the enduring impact of Hukum Kanun Pahang (Pahang Laws) in Malaysian society
Authors: Muslim Nazri , Mohamed Amaal Fadhlini , Arham Ahmad Firdhaus 
Published: June 2024

AbstractThe legal system known as Hukum Kanun Pahang, or Pahang Laws, was established during the reign of Sultan Abdul Ghafur Muhayiddin Syah (1592–1614), the 12th Sultan of Pahang. The enduring influence of the legal system on the Institution of the Malay Sultanate has had a profound and ongoing effect on the societal structure of Malaysian society. The enduring influence of the Pahang Laws on the Institutions of the Malay Sultanate serves as a testament to the significance of safeguarding cultural legacy and maintaining social cohesion, despite the challenges posed by colonialism and globalization. This study investigates the worldwide ramifications of Pahang Laws, which are inspired by Islamic Law, and analyses the extent to which this legal framework contributes to the implementation of justice within the Malaysian social system. This study illuminates the significance of the legal system in the Malay Sultanate, providing valuable insights that can serve as a reference point for the development of legal frameworks in other countries sharing similar demographics and cultures. Particularly, it has the potential to shape the socio-legal environment of Southeast Asia and beyond.
Human development and disaster mortality: evidence from India

Published: June 2024

AbstractNatural disasters present substantial dangers to both human life and physical infrastructure. Although the human development index (HDI) is recognized for its pivotal role in mitigating mortality resulting from natural disasters, the exact extent of its impact on fatalities remains unclear. In this study, we investigate the relationship between HDI and fatalities resulting from floods and cyclones using panel data for 19 states of India spanning from 1983 to 2011. Employing Fixed Effects Poisson and Negative Binomial estimates, we establish a causal-effect relationship between HDI and disaster-related fatalities. Additionally, we utilize the Instrumental Variable Poisson (IV) model to address the endogeneity between HDI and fatalities. Our empirical findings indicate that states with higher HDI levels experience lower fatalities due to natural disasters. Furthermore, our results underscore the importance of critical policy discussions regarding the role of inequality-adjusted HDI, government responsiveness, and human capital development in disaster risk reduction strategies.
Choice of Device II: Strength of Reasons
Authors: Chan Cora 
Published: June 2024

Abstract
The chapter explores which device/combination of devices courts should use to give effect to the strength of the reason for deference. It compares the range and granularity of deference expressible by the six devices, arguing that the range and granularity expressible by the burden of proof are smaller/less than those expressible by other devices. The chapter argues that when deference is exercised at the definition and limitation stages in ways that lead to favourable outcomes for the primary decision-maker at those two stages, the degree of deference manifested at the three stages—defintion, limitation, remedy—is, as some have assumed, in decreasing order. The chapter then examines the combinability of devices. It defines the double counting of deference: double counting occurs when a court gives undue additional weight to a ground served by deference. Understood as such, deference using more than one device does not necessarily lead to double counting.

Abstract
This chapter first summarizes the book’s arguments. It then demonstrates how the four sets of techniques proposed in Chapter 6 can be put into practice by combining them into four models: the algorithmic model, stable model, elastic model, and amorphic model (in increasing order of flexibility). It illustrates how the four models can be applied using the case of Hong Kong. The chapter then draws a connection between the demands of internal logic and those of external constraints, presents examples of the empirical data needed to draw conclusive observations using the book’s ideas, and highlights several directions for future research.
Continued harmonization of the international normalized ratio across a large laboratory network: Evidence of sustained low interlaboratory variation and bias after a change in instrumentation
Authors: Favaloro Emmanuel J , Arunachalam Sandya , Chapman Kent , Pasalic Leonardo 
Published: June 2024

Abstract

Objectives
Our objective was to maintain low interlaboratory variation and bias in international normalized ratio (INR) results following a network change in instrumentation and reagents, using a process of ongoing standardization and harmonization.

Methods
Network-wide standardization to new common instrument and reagent platforms followed by network-wide application of a simple novel process of verification of international sensitive index and mean normal prothrombin time values for each new lot of prothrombin time (PT) reagent that does not require use of World Health Organization reference thromboplastin or INR calibration/certified plasma.

Results
The network transitioned from mechanical hemostasis detection instruments with associated PT reagent (Diagnostica Stago; NeoPTimal) to optical detection (ACL TOPs) with associated PT reagent (Werfen; RecombiPlasTin 2G). Comparing 3 years of data for each situation, the network (n = 27 laboratories) maintained low INR variability and bias relative to general mechanical and optical groups and other laboratories.

Conclusions
Harmonized support for patient management of vitamin K antagonists such as warfarin was continuously maintained in our geography, with potentially positive implications for other coagulation laboratories and geographies. For the United States in particular, paucity of US Food and Drug Administration–cleared INR certified plasmas potentially compromises INR test accuracy; our novel approach may provide workable alternatives for other laboratories/networks.
