A Trajectory Privacy-Preserving Scheme Based on Transition Matrix and Caching for IIoT

With the increasing integration of location-based services (LBSs) into various societal domains, location privacy preservation has emerged as a pivotal concern. In most continuous LBS privacy protection approaches, the user needs to send a query to an untrusted location service provider (LSP) to request the corresponding query results, and these results are discarded immediately after being used. This leads to similar queries in the future having to be sent to the LSP again, which increases the risk of privacy leakage when facing the LSP. To solve these issues, caching techniques are typically used to provide answers to users’ future queries. However, minimizing the interaction with the LSP is a challenge. Here, we propose a trajectory privacy-preserving scheme based on a transition matrix and caching (TMC) scheme for continuous LBS in the Industrial Internet of Things (IIoT). It employs multilevel caching to reduce the risk of exposing sensitive information to untrusted entities. We designed a transition matrix to predict the user’s next query location and simplify the computation complexity. We designed a cloaking set generation algorithm by considering transition entropy, location prediction, data freshness, and cache contribution degree to enhance user location privacy and improve the cache hit rate. The security analysis demonstrates how the TMC scheme resists attacks from both internal and external entities and ensures robustness in trajectory privacy. The experimental results show that the proposed TMC scheme can provide a higher level of privacy protection and lower system overhead compared to several previous schemes.

The current study aimed at investigating the psychometric properties of School Connectedness Scale (SCS) among 9th & 10th grade students at Al-Queismeh Directory schools in Jordan. The Arabic version of Lohmeier and Lee (2011) scale was applied to a sample of (374) students including both males and females. This was done after the initial verification of the Psychometric properties of the scale on an exploratory sample of (53) male and female students. The results of the study showed that the factorial structure of the school connectedness scale is a complex structure. The analysis of the data using principal components leads to five factors. The five factors showed (43.395 %) from the variance of the items. The results of the reliability, using Cronbach Alpha, also showed good indicters (0.60 – 0.92). The results of split-half also showed good indicaters (0.62 – 0.88). The researchers recommended the possibility of using the scale for the Jordanian environment because of its acceptable psychometric properties.
Evaluation of Policies for the Implementation of Social Welfare for Women in Socio-Economic Vulnerabilities in Sukabumi City

The purpose of this study is to describe and find out about the Evaluation of Policies for the Implementation of Social Welfare for Socio-Economic Vulnerable Women in Sukabumi City. In this study, the research method used was a qualitative method with a descriptive approach. The analytical techniques in this study were data reduction, data presentation, and analysis. conclusion. The results showed that on the Context Evaluation dimension, the welfare goals for WRSE can be said to be good, it's just that the existing budget constraints make the implementation not run properly. In the Input Evaluation dimension, the increase in the social welfare of people with WRSE has not been significant. In the Process Evaluation dimension, the obstacles experienced by KUBE members who are WRSE sufferers, are overall due to the lack of attention and thoroughness from the policy implementers towards the KUBE they foster. In the Product Evaluation dimension, the existence of this empowerment program will have a positive impact on the lives of themselves and other WRSE sufferers, but there are still improvements from the Sukabumi City Social Service as policy implementers and decision makers in every KUBE activity.

Weighted Filtered Back-Projection for Source Translation Computed Tomography Reconstruction

Micro-computed tomography (micro-CT) is an indispensable tool to provide attenuation-based, high-resolution 3-D images in scientific research. However, its current available configuration limits the size of objects that can be imaged. Previously, we have proposed a multiple source translation computed tomography (mSTCT) imaging geometry to extend the field-of-view (FOV) of micro-CT, and developed a corresponding reconstruction algorithm called virtual projection-based filtered back-projection (V-FBP). V-FBP achieves high-resolution reconstructions when the source is densely sampled but fails if the source is coarsely sampled. In this article, to achieve high-resolution reconstruction at a low source sampling rate, we propose a full-scan multiple-STCT (F-mSTCT) scanning configuration, which allows for a simple and effective weighting function to deal with data redundancy and truncation simultaneously. Based on this concept, we develop a weighted FBP (W-FBP) algorithm. The numerical and physical experiments demonstrate that W-FBP is able to reconstruct high-resolution images at a low source sampling rate, and can reduce 1/2–3/4 projections compared with V-FBP at the same resolution.
Motivating Employees through Job Design and Compensation: An Observation

This study aims to examine the relationship and impact of job design and compensation on employee motivation. It is based on primary data obtained by distributing questionnaires to 15 Nepalese business organizations. The results show that job design has a significant positive relationship with employee motivation. In the same way, the results demonstrate that compensation has a significant positive relationship with employee motivation. In fact, employees who think their jobs are well-designed are highly motivated at work. Moreover, employees are highly motivated at work when they perceive a fair and efficient compensation system. Therefore, to enhance employee motivation, organizations must redesign job policies and foster employee trust. They also need to develop trusting compensation and incentive systems for their employees to increase employee motivation.
Dual Band Coaxial Y-Monopole for Hyperthermia Treatment of Cervical Cancer Delivered Through an Intrauterine Tandem

In this work, we report a coaxial antenna consisting of a flexible Y-monopole with dual-band operation and low-profile wideband flexible ferrite choke for delivering localized HT treatment at shallow insertion depth of 50 mm inside the cervix using custom fabricated non-metallic intrauterine cervix tandem of 8 mm outer diameter and 1 mm wall thickness. Variable treatment coverage was achieved by selecting the excitation of the dual-band Y-monopole as 915 and 1300 MHz. The Y-monopole is a coaxial wire with a Y-split in the exposed inner conductor and wideband flexible ferrite sheet on the outer conductor to suppress the secondary current. The water loaded Y-monopole inside the intrauterine tandem cervix applicator with 15° bend angle resonated at 915 and 1300 MHz for arm lengths of 21 and 13.5 mm, respectively. The heating characteristics of Y-monopole was assessed using tissue-mimicking phantoms. Phantom measurements indicate dual band operation with power reflection coefficient $ \leq -$ 24 dB at 915 and 1300 MHz. The measured extents of 25% axial specific absorption rate in tissue phantom at 915 and 1300 MHz is 39.4 and 28.4 mm, respectively. Localized power deposition with $\Delta T = 3$ °C iso-contour of 46.3 mm × 39.2 mm and 37 mm × 31 mm along axial and radial directions was measured at 915 and 1300 MHz, respectively. Phantom measurements demonstrate the ability of the proposed antenna to deliver variable treatment volume to the cervix through 15° intrauterine tandem.
Kinetics of Cold Ions in Asymmetric Reconnection: Particle‐In‐Cell Simulation

Cold ions from Earth's ionosphere and plasmasphere have frequently been observed at the magnetopause, where they impact reconnection and get energized in the process. The behavior of cold ions in different regions of magnetopause reconnection is not well understood. This study investigates their kinetics in asymmetric reconnection through a 2.5‐D fully kinetic simulation. The simulation starts with cold ions being present only in the magnetosphere. We find that the velocity distribution functions (VDFs) of cold ions in different reconnection regions are composed of two types of particles, distinguished by their ability to penetrate the magnetosheath. One type produces ring‐shaped distributions in the magnetosheath due to meandering motion, while the other generates ring‐shaped distributions in the magnetospheric separatrix as a result of gyromotion. The reconnection electric field Ey has a negative effect on one type and a positive effect on the other. Moreover, the Hall electric field Ez can stepwise accelerate the meandering particles. The cold ion temperature increases significantly in the magnetosheath as compared to its original temperature, the enhancement is a kinetic effect as a result of the ring‐shaped velocity distribution. On the other hand, in the remaining regions, cold ions experience bulk heating, resulting in noticeable temperature elevation. These findings further emphasize the necessity to examine the VDF for an all‐round comprehension of the particle heating mechanism and contribute to a better understanding of cold ion dynamics at the Earth's magnetopause.

Written by leading international scholars, it offers new insight into emergent behaviours, motivations and sought meanings on the part of tourists based on five contemporary themes determined by current research activity in tourism experience:conceptualization of tourist experience; dark tourism experiences; the relationship between motivation and the contemporary tourist experience; the manner in which tourist experience can be influenced and enhanced by place; and how managers and suppliers can make a significant contribution to the tourist experience. The book critically explores these experiences from multidisciplinary perspectives and includes case studies from wide range of geographical regions. By analyzing these contemporary tourist experiences, the book will provide further understanding of the consumption of tourism.
Influence of cysteamine supplementation during in vitro culture of early stage caprine embryos on blastocyst production

The objective of this study was to evaluate the effect of cysteamine supplementation on embryo development in mCR2 media. The COCs (1251) were matured in TCM–199 medium containing FSH (5µg/ml), LH (10µg/ml), follicular fluid (10%), FBS (10%) with 3 mg/ml BSA for 27h at 38.5°C and 5% CO2 in an incubator. Matured oocytes were co-cultured with 1×106 spermatozoa/ml collected from a Sirohi buck in fertTALP (10% FBS+ 4mg/ml BSA and 10 µg/ml heparin) for 18 h in incubation. After 18 h of sperm-oocytes, co-incubation of oocytes with sperms were washed in embryo development medium to remove sperm cells adhered to zonapellucida. Presumptive zygotes (1,171) were selected and randomly divided into 2 groups. Group 1, the presumptive zygotes (610) were cultured in mCR2aa as a control for 12 days. Group 2, the presumptive zygotes (561) were culture in mCR2aa medium supplemented with 100 µM cysteamine for 10 days. The percentage of cleavage, morula, and blastocyst production in groups 1 and 2 were 36.39% and 31.71% (cleavage); 21.62% and 30.89% (morula); 4.95% and 8.98% (blastocyst) respectively. In conclusion, results indicated that the addition of cysteamine to the IVC medium stimulates caprine embryo development and blastocyst production.
A Theoretical Model of Underground Dipole Antennas for Communications in Internet of Underground Things

The realization of Internet of underground things (IOUT) relies on the establishment of reliable communication links, where the antenna becomes a major design component due to the significant impacts of soil. In this paper, a theoretical model is developed to capture the impacts of the change of soil moisture on the return loss, resonant frequency, and bandwidth (BW) of a buried dipole antenna. Experiments are conducted in silty clay loam, sandy, and silt loam soil, to characterize the effects of soil, in an indoor testbed and field testbeds. It is shown that at subsurface burial depths (0.1–0.4 m), the change in soil moisture impacts communication by resulting in a shift in the resonant frequency of the antenna. Simulations are done to validate the theoretical and measured results. This model allows system engineers to predict the underground antenna resonance and also helps to design an efficient communication system in IOUT. Accordingly, a wideband planar antenna is designed for an agricultural IOUT application. Empirical evaluations show that an antenna designed considering both the dispersion of soil and the reflection from the soil–air interface can improve communication distances by up to five times compared to antennas that are designed based on only the wavelength change in soil.
Invisible Digital Image by Thin-film Interference of Niobium Oxide using its Periodic Repeatability

SUMMARY There are several beneﬁts of the information that is invis-ible to the human eye. “Invisible” here means that it can be visualized or quantiﬁed when using instruments. For example, it can improve security without compromising product design. We have succeeded in making an invisible digital image on a metal substrate using periodic repeatability by thin-ﬁlm interference of niobium oxides. Although this digital information is invisible in the visible light wavelength range of 400-800nm, but detectable in the infrared light that of 800-1150nm. This technology has a potential to be applied to anti-counterfeiting and traceability.
Darkness at night during the new moon period alters the expression levels of the clock genes in the brain of a moon-related spawner, the Malabar grouper Epinephelus malabaricus

ABSTRACT Some fish in tropical and subtropical waters exhibit moon-related rhythmicity in their reproduction and migration. We investigated the involvement of the subtypes of cryptochrome (mgCry) in moon-related rhythmicity of the Malabar grouper Epinephelus malabaricus, which spawns around the new moon period. Under natural photoperiodic conditions, the levels of mgCry1 and mgCry2 showed daily variation with peaks at 11:00 and 19:00, respectively, in the diencephalon (including the pituitary), regardless of the moon phase. The weekly changes in mgCry2, but not mgCry1, were moon-dependent, with higher levels around the new moon. When fish were reared under natural moonlight, mgCry2 in the pituitary was higher at 15:00 and 11:00 during the new moon period than the full moon period. Rearing fish under moonlight-exposed or moonlight-blocked conditions resulted in increases in mgCry genes in the pituitary during the night at full moon, suggesting that the pituitary is a target organ of the moonlight-dependent clock system. These findings indicate that mgCry genes in the brain of the Malabar grouper exhibits moon dependency, with changes according to the duration of darkness at night. We conclude that weekly changes in Cry genes in the brain play a role in entraining moon-dependent events in the Malabar grouper.
Simulazione dinamica non lineare di superfici estese collegate mediante contatto per attrito = Non-linear dynamic simulation of wide surfaces coupled by means of friction contact

L'analisi dinamica e essenziale per la progettazione dei sistemi meccanici. I sistemi meccanici spesso prevedono elementi connessi tramite varie tecniche di collegamento e molti studi affrontano questo aspetto con differenti approcci al problema. In particolar modo e stata posta l’attenzione sulla modellazione delle superfici di contatto in presenza di una forzante esterna e sulla modellazione dell'attrito. Inoltre, vengono proposte delle soluzioni per tener conto dell’incertezza delle proprieta del materiale e delle condizioni al contorno perche incidono in maniera importante sul comportamento dinamico del sistema. Si osserva che un sistema meccanico sottoposto ad un carico esterno variabile nel tempo presenta dei fenomeni di rilassamento e allentamento del vincolo che amplifica l’ampiezza della risposta del sistema e che influenza anche la vita a fatica del sistema. Dall’analisi sperimentale di un accoppiamento di due travi tramite otto magneti si e osservato il suo comportamento dinamico al variare della forzante esterna. L'obiettivo di questo studio e quello di ricreare il modello su Ansys per determinare a livello numerico il comportamento dinamico delle superfici estese collegate mediante contatto per attrito. E stato studiato il comportamento dinamico del modello al variare del coefficiente di attrito, della forzante esterna e della discretizzazione della mesh del modello. La simulazione dinamica non lineare e stata poi confrontata con l'analisi sperimentale.
