Published: November 2023

ObjectiveLarger diameter sutures can provide sufficient tensile strength to surgical incisions but may exacerbate the inflammatory response caused by the amount of implanted foreign material. This experiment aims to investigate the differences in biomechanical stability and tissue reactivity after suturing canine midline abdominal incisions with different suture sizes.MethodAssessing the biomechanical differences between USP 2-0, 3-0, and 4-0 PGA sutures using uniaxial tensile testing on ex vivo canine midline skin and fascial muscle tissues using either a simple continuous or simple interrupted technique. mRNA and protein expression levels of inflammatory factors were measured through RT-PCR and ELISA. Tissue reactivity was evaluated using a semi-quantitative scoring system.ResultFor strains below 30% in skin and below 50% in muscle, there were no significant differences among groups. The results of skin biomechanical testing showed that the USP 4-0 PGA suture group demonstrated significantly lower maximum tensile strength compared to the USP 2-0 PGA or USP 3-0 PGA suture groups. However, it remained capable of providing at least 56.3 N (1.03 MPa) tensile strength for canine skin incisions, matching the tensile strength requirements of general canine abdominal wall surgical incisions. In addition, there were no statistically significant differences observed in the maximum tensile strength among different size of sutures according to the data of biomechanical testing in muscle. Larger diameter sutures led to increased levels of inflammatory factors (IL-1β, IL-6, TNF-ɑ) and tissue reactivity. Simple interrupted sutures caused higher levels of inflammatory factors in muscular tissue compared to simple continuous sutures.ConclusionUSP 4-0 PGA sutures provide sufficient biomechanical stability for suturing canine abdominal skin and linea alba. Suture size significantly influences tissue reactivity after suturing, with smaller gauge sutures reducing early tissue inflammatory response. Thus, USP 4-0 PGA suture has more advantages to suturing canine abdominal surgical incisions.

To enhance the holographic properties, one of the main methods is increasing the solubility of the photosensitizer and modifying the components to improve the modulation of the refractive index in the photopolymer. This study provides evidence, through the introduction of a mutual diffusion model, that the incorporation of SiO2 nanoparticles in photopolymers can effectively enhance the degree of refractive index modulation, consequently achieving the objective of improving the holographic performance of the materials. Different concentrations of SiO2 nanoparticles have been introduced into highly soluble photosensitizer Irgacure 784 (solubility up to 10wt%)-doped poly-methyl methacrylate (Irgacure 784/PMMA) photopolymers. Holographic measurement experiments have been performed on the prepared samples, and the experiments have demonstrated that the Irgacure 784/PMMA photopolymer doped with 1.0 × 10−3wt% SiO2 nanoparticles exhibits the highest diffraction efficiency (74.5%), representing an approximate 30% increase in diffraction efficiency as compared to an undoped photopolymer. Finally, we have successfully achieved the recording of real objects on SiO2/Irgacure 784/PMMA photopolymers, demonstrated by the SiO2/Irgacure 784/PMMA photopolymer material prepared in this study, which exhibits promising characteristics for holographic storage applications. The strategy of doping nanoparticles (Nps) in Irgacure 784/PMMA photopolymers has also provided a new approach for achieving high-capacity holographic storage in the future.

Цель исследования — обобщение и виктимологическая оценка спонтанных мер борьбы с виктимизацией и определение антивиктимных средств противодействия негативным факторам в пожилом возрасте. Было установлено, что в настоящее время не существует общепризнанных теоретически обоснованных позитивных стратегий функционирования личности в пожилом возрасте. Доминирует тенденция описания пожилого человека не как субъекта деятельности, а как пассивного объекта воздействия, что порождает геронтологический эйджизм и формирует у пожилого человека позицию жертвы. В эмпирической части исследования приняли участие 90 человек разного социального статуса — предпенсионеры, работающие и неработающие пенсионеры. Было выявлено, что антивиктимные свойства личности — антивиктимные установки, антивиктимная жизненная позиция и внутренний локус-контроль позволяют пожилому человеку успешно преодолевать виктимологические угрозы, возникающие в пожилом возрасте, сохраняя и защищая основные резервы своей личности — самоуважение и личное достоинство. Описаны основные обобщенные антивиктимные инструменты, создающие условия для реализации позитивных жизненных стратегий в пожилом возрасте, — комплексность, ритмизация жизни, компенсаторность и нетворкинг.
The aim of the study was to generalize and assess victimological spontaneous measures to combat victimization and to identify anti-victim means to counteract negative factors in old age. It was found that at present there are no generally recognized theoretically substantiated positive strategies for the functioning of the personality in old age. The dominant tendency is to describe an elderly person not as a subject of activity, but as a passive object of influence, which gives rise to gerontological ageism and forms the position of a victim in an elderly person. The empirical part of the study involved 90 people of different social status: prepensioners, working and non-working pensioners. It was found that anti-victim personality traits: anti-victim attitudes, anti-victim life position and internal locus of control allow an elderly person to successfully overcome victimological barriers that arise in old age, while maintaining and protecting the main reserve of his personality: self-esteem and personal dignity. The main generalized anti-victim tools that create conditions for the implementation of positive life strategies in old age are described: complexity, rhythmization of life, compensatory and networking.

To reduce water losses in the Samara municipal water supply system the specialists of Samara Utility Systems LLC have been monitoring the volume of water delivered to the inspected local water supply zones for more than 10 years. During this period, various approaches to this work were tested; the requirements to the observed parameters were determined, and solutions were found to problems that impede the effective control of the operation of the water supply and distribution system. Based on the experience gained, the main difficulties that interfere with the described work have been identified: interruptions in data transfer to the SCADA system, incorrect values in the database; errors of pressure gauges in buildings and a small number of points for measuring pressure in the local water supply zones; consumers who pay for the water services by standards and do not have metering devices.
Discovering Premature Replacements in Predictive Maintenance Time-to-Event Data

Published: November 2023

Time-To-Event (TTE) modeling using survival analysis in industrial settings faces the challenge of premature replacements of machine components, which leads to bias and errors in survival prediction. Typically, TTE survival data contains information about components and if they had failed or not up to a certain time. For failed components, the time is noted, and a failure is referred to as an event. A component that has not failed is denoted as censored. In industrial settings, in contrast to medical settings, there can be considerable uncertainty in an event; a component can be replaced before it fails to prevent operation stops or because maintenance staff believe that the component is faulty. This shows up as “no fault found” in warranty studies, where a significant proportion of replaced components may appear fault-free when tested or inspected after replacement.
In this work, we propose an expectation-maximization-like method for discovering such premature replacements in survival data. The method is a two-phase iterative algorithm employing a genetic algorithm in the maximization phase to learn better event assignments on a validation set. The learned labels through iterations are accumulated and averaged to be used to initialize the following expectation phase. The assumption is that the more often the event is selected, the more likely it is to be an actual failure and not a “no fault found”.
Experiments on synthesized and simulated data show that the proposed method can correctly detect a significant percentage of premature replacement cases.

Published: November 2023

The goal of predictive maintenance (PdM) is to facilitate on-condition maintenance or reduce/eliminate unscheduled maintenance events. For critical systems such as aircraft,PdM improves safety while increasing operational readiness. Aircraft operators can order the parts and ensure the correct skills and tools are available to avoid unplanned downtime.An enabler for PdM is the need to estimate the remaining useful life (RUL). For RUL to be accurate, there needs to be an assessment of the current component health, a thresholdfor when it is appropriate to do maintenance, and a degradation model. This model could be based on some physical processes, such as high-cycle fatigue failure.However, often the exact fatigue process is unknown. In this paper, a quadratic RUL model is used to calculate RUL using a state estimator. The proposed process allows for modelvalidation of the RUL state estimator itself. This is demonstrated using a bearing fault, a gear fault, and oil debris example.

<p>This paper presents a Millimeter wave Microstrip Patch antenna(MPA) with a metaplate which consists of Split Ring resonators(SRR) design. The gain and bandwidth of MPA are improved by using 4×3 array unit cells printed on both the sides of the metaplate. Simulation results show that the Gain of the antenna was increased by 4.82 dBi and 4.53 dBi, bandwidth was increased by 2.25% and 6.21% in CST and HFSS softwares respectively using the Metaplate along with the MPA. The center frequency of the proposed antenna is 28.5 GHz. Thus the proposed antenna has a very small size of 18×22 mm2 and is suitable for Millimeter wave applications </p>
Directional Modulation for Enhanced Privacy in Smart Watch Devices

Published: November 2023

<p>This article studies security aspects of data transmission in on-body Internet of Things (IoT) devices through the use of Directional Modulation (DM) from a smart watch integrated antenna. DM is a beamsteering-based Physical Layer Security (PLS) method used to transmit baseband constellations to known secure locations, while simultaneously scrambling them in other directions. However, in the state-of-the-art DM is implemented using large arrays, which are out-sized for many on-body IoT devices. To overcome this challenge, this study proposes multimodal ultra-thin compact antennas suitable for integration into smart watches. These antennas present advanced beamsteering capabilities that allow the implementation of DM from a low-thickness structure of up to 0.57 mm or 1/100th of wavelength at the center operating frequency. Two different DM implementations<br>
(simultaneous multiport transmission and an energy-efficient single-port transmission) are tested using a multi-layer phantom. Overall, secure steerable transmissions are realized, and experimental verifications are carried out to validate the proposed concept. Ultimately, this article demonstrates the feasibility of applying new energy-efficient and low-cost security techniques to enhance the privacy of resource-constrained IoT devices. </p>
Real-time Ultrasound Imaging Based Muscle Feedback To Inform Afferent Stimulation For Tremor Suppression
Authors: Sharma Nitin 
Published: November 2023

<p> Tremors due to Essential Tremor (ET) and Parkinson’s Disease (PD) often result in involuntary oscillations of human limbs that impact daily activities such as eating, drinking, and writing. Recently, afferent stimulation of peripheral nerves has emerged as a new non-invasive approach to tremor suppression. To increase its efficacy there is a desire to develop sensing and control strategies the complement the emerging suppression approach. Motivated by technical challenges to deploy prevalent sensing methods for tremor characterization we investigated real-time ultrasound (US)-imaging derived signal to cue afferent stimulation times. To achieve this, we first derived a real-time US-image based metric to characterize tremor in participants with ET and PD. We further determined an effective afferent stimulation frequency for each participant that achieved the best tremor suppression. Finally for the first time, we present results from the implementation of real-time US-imaging that triggers afferent stimulation (on or off) on the onset or subsidence of the wrist tremor in three participants with PD and ET .</p>
Distributed Repairing Multiple Erasures in Reed-Solomon Codes
Authors: Lin Xing 
Published: November 2023

<p>The application of Reed-Solomon (RS) codes in distributed storage systems is widespread. A lot of literature have proposed repair schemes for RS codes with one or multiple failed symbols, which can reduce communication cost during repair (i.e. repair bandwidth).</p>
<p> However, for repair schemes of RS codes with multiple failed symbols, the existing distributed repair schemes can only repair $e=2,3$ erasures. In this paper, by intelligently dividing the set of evaluation points corresponding to failed symbols, a distributed repair scheme for RS codes with $e\geq 4$ erasures are proposed.</p>

Semantic Communication: A Survey on Research Landscape, Challenges, and Future Directions
Authors: Getu Tilahun , Kaddoum Georges , Bennis Mehdi 
Published: November 2023

<p> Amid the global rollout of fifth-generation (5G) services, researchers in academia, industry, and national labo?ratories have been developing proposals for the sixth generation (6G). Despite the many 6G proposals, the materialization of 6G as presently envisaged is fraught with many fundamental interdisciplinary, multidisciplinary, and transdisciplinary (IMT) challenges. To alleviate some of these challenges, semantic com?munication (SemCom) has emerged as promising 6G technology enabler. SemCom is designed to transmit only semantically?relevant information and hence help to minimize power usage, bandwidth consumption, and transmission delay. Thus, SemCom embodies a paradigm shift that can change the status quo that wireless connectivity is an opaque data pipe carrying messages whose context-dependent meaning have been ignored. On the other hand, 6G is critical for the materialization of major SemCom use cases. These paradigms of 6G for SemCom and SemCom for 6G call for a tighter integration and marriage of 6G and SemCom. To facilitate this integration and marriage, this comprehensive survey paper first provides the fundamentals of semantics and semantic information, semantic representation, semantic information, and semantic entropy. It then builds on this understanding and details the state-of-the-art research landscape of SemCom; exposes the fundamental and major challenges of SemCom; and offers promising future research directions for SemCom theories, algorithms, and realization. Accordingly, this survey article stimulates major streams of research on SemCom theories, algorithms, and implementation. </p>
