Published: July 2023

Quantum key distribution (QKD) is a promising technique to resist the threat against quantum computers. However, the high loss of quantum signals over a long-distance optical fiber is an obstacle for QKD in the intercontinental domain. In this context, the quantum satellite network is preferred over the terrestrial quantum optical network. Due to the mobility of satellites, the satellite topology is dynamic in the quantum satellite network, which remains a challenge for routing. In hybrid geostationary-earth-orbit (GEO)/low-earth-orbit (LEO) quantum satellite networks, the lack of an efficient scheduling scheme for GEO/LEO satellites also limits the construction of quantum satellite networks. Therefore, this paper provides a topology abstraction-based routing scheme for secret-key provisioning, where the dynamic physical topology is translated into a quasi-static abstracted topology. This scheme contributes to saving the precious secret key resources. In order to improve the success probability of long-distance QKD requests, three novel resource-scheduling heuristic algorithms are proposed in hybrid GEO/LEO quantum satellite networks. Simulation results indicate that the proposed algorithms can improve the success probability of QKD requests by 47% compared to the benchmark.

Published: July 2023

The transformation of high-molecular DNA from a random swollen coil in a solution to a discrete nanosized particle with the ordered packaging of a rigid and highly charged double-stranded molecule is one of the amazing phenomena of polymer physics. DNA condensation is a well-known phenomenon in biological systems, yet its molecular mechanism is not clear. Understanding the processes occurring in vivo is necessary for the usage of DNA in the fabrication of new biologically significant nanostructures. Entropy plays a very important role in DNA condensation. DNA conjugates with metal nanoparticles are useful in various fields of nanotechnology. In particular, they can serve as a basis for creating multicomponent nanoplatforms for theranostics. DNA must be in a compact state in such constructions. In this paper, we tested the methods of DNA integration with silver, gold and palladium nanoparticles and analyzed the properties of DNA conjugates with metal nanoparticles using the methods of atomic force microscopy, spectroscopy, viscometry and dynamic light scattering. DNA size, stability and rigidity (persistence length), as well as plasmon resonance peaks in the absorption spectra of systems were studied. The methods for DNA condensation with metal nanoparticles were analyzed.
A Newly Established Cuproptosis-Related Gene Signature for Predicting Prognosis and Immune Infiltration in Uveal Melanoma
Authors: Huang Wei , Yang Fan , Zhang Yichi , Fang Qianqi , Lai Yitao , Lan Yuqing
Published: July 2023

Uveal melanoma (UVM) is the most common primary ocular malignancy in adults and involves several types of regulated cell death. Cuproptosis is a novel method of regulating cell death by binding lipoylated TCA cycle proteins. There is still no research on the relationship between cuproptosis-related genes (CRGs) and UVM. Here, we aimed to develop a prognostic CRG signature for UVM. After a prognostic CRG signature was constructed, we determined the relationship between the signature and immune infiltration, bioinformatics analysis and experimental validation. Finally, a prognostic cuproptosis-related three-gene (CRTG) signature was constructed, which comprised ORAI2, ACADSB and SLC47A1. The risk score of the CRTG signature was negatively correlated with the overall survival (OS) and progression-free survival (PFS) of patients, which revealed strong predictive ability and its independent prognostic value. In addition, we found that the risk score was negative for chromosomes 3 and 6p, and positive for 8q, and high-risk UVM patients showed an increase in protumor immune infiltrates and a high expression of immune checkpoints. Finally, experimental validation verified that the migratory ability of MUM-2B cells was suppressed by the knockdown of the identified genes in vitro. We constructed a CRTG signature that is helpful in predicting prognosis and guiding treatment for patients with UVM.
Deciphering the Signaling Mechanisms of Osteosarcoma Tumorigenesis
Authors: Nirala Bikesh K. , Yamamichi Taku , Yustein Jason T.
Published: July 2023

Osteosarcoma (OS) is the predominant primary bone tumor in the pediatric and adolescent populations. It has high metastatic potential, with the lungs being the most common site of metastasis. In contrast to many other sarcomas, OS lacks conserved translocations or genetic mutations; instead, it has heterogeneous abnormalities, including somatic DNA copy number alteration, ploidy, chromosomal amplification, and chromosomal loss and gain. Unfortunately, clinical outcomes have not significantly improved in over 30 years. Currently, no effective molecularly targeted therapies are available for this disease. Several genomic studies showed inactivation in the tumor suppressor genes, including p53, RB, and ATRX, and hyperactivation of the tumor promoter genes, including MYC and MDM2, in OS. Alterations in the major signaling pathways, including the PI3K/AKT/mTOR, JAK/STAT, Wnt/β-catenin, NOTCH, Hedgehog/Gli, TGF-β, RTKs, RANK/RANKL, and NF-κB signaling pathways, have been identified in OS development and metastasis. Although OS treatment is currently based on surgical excision and systematic multiagent therapies, several potential targeted therapies are in development. This review focuses on the major signaling pathways of OS, and we propose a biological rationale to consider novel and targeted therapies in the future.

Published: July 2023

Mycobacterium tuberculosis complex causes tuberculosis (TB), a disease that causes pulmonary inflammation but can also affect other tissues. Despite macrophages having a defined role in TB immunopathogenesis, other innate immune cells, such as neutrophils, are involved in this process. These cells have high phagocytic ability and a microbial-killing machine comprised of enzymes, antimicrobial peptides, and reactive oxygen species. In the last two decades, a new neutrophil immune response, the neutrophil extracellular traps (NETs), has been intensely researched. NETs comprise DNA associated with histones, enzymes, and antimicrobial peptides. These structures are related to antimicrobial immune response and some immuno-pathogenesis mechanisms. This mini review highlights the role of NETs in tuberculosis and how they can be helpful as a diagnostic tool and/or therapeutic target.
Wi-Fi-Based Indoor Localization and Navigation: A Robot-Aided Hybrid Deep Learning Approach
Authors: Lin Xuxin , Gan Jianwen , Jiang Chaohao , Xue Shuai , Liang Yanyan
Published: July 2023

Indoor localization and navigation have become an increasingly important problem in both industry and academia with the widespread use of mobile smart devices and the development of network techniques. The Wi-Fi-based technology shows great potential for applications due to the ubiquitous Wi-Fi infrastructure in public indoor environments. Most existing approaches use trilateration or machine learning methods to predict locations from a set of annotated Wi-Fi observations. However, annotated data are not always readily available. In this paper, we propose a robot-aided data collection strategy to obtain the limited but high-quality labeled data and a large amount of unlabeled data. Furthermore, we design two deep learning models based on a variational autoencoder for the localization and navigation tasks, respectively. To make full use of the collected data, a hybrid learning approach is developed to train the models by combining supervised, unsupervised and semi-supervised learning strategies. Extensive experiments suggest that our approach enables the models to learn effective knowledge from unlabeled data with incremental improvements, and it can achieve promising localization and navigation performance in a complex indoor environment with obstacles.

Authors: Alhamad Rami , Seth Nitin , Abdullah Hussein A.
Published: July 2023

The preliminary test results of a novel robotic hand rehabilitation device aimed at treatment for the loss of motor abilities in the fingers and thumb due to stroke are presented. This device has been developed in collaboration with physiotherapists who regularly treat individuals who have suffered from a stroke. The device was tested on healthy adults to ensure comfort, user accessibility, and repeatability for various hand sizes in preparation for obtaining permission from regulatory bodies and implementing the design in a full clinical trial. Trials were conducted with 52 healthy individuals ranging in age from 19 to 93 with an average age of 58. A comfort survey and force data ANOVA were performed to measure hand motions and ensure the repeatability and accessibility of the system. Readings from the force sensor (p < 0.05) showed no significant difference between repetitions for each participant. All subjects considered the device comfortable. The device scored a mean comfort value of 8.5/10 on all comfort surveys and received the approval of all physiotherapists involved. The device has satisfied all design specifications, and the positive results of the participants suggest that it can be considered safe and reliable. It can therefore be moved forward for clinical trials with post-stroke users.
Fasys: Visible-Light-Based Communication and Positioning Services towards Smart Cities
Authors: Yu Baozhu , Liu Xiangyu , Guo Lei , Wei Xuetao , Song Song
Published: July 2023

Visible-light-based transmission application plays an important role in various types of sensor services for the Internet of Things (IoTs). However, in big data scenarios, current visible-light-based systems cannot achieve concurrent high-speed communication, low-speed communication, and positioning. Therefore, in this article, we propose a smart visible-light-based fusion applications system, named Fasys, to solve the above problem for the big data traffic with heterogeneity. Specifically, for low-speed data services, we propose a novel linear block coding and bit interleaving mechanism, which enhances the LED positioning accuracy and recovers the lost data bits in the interframe gap (IFG). For high-speed data services with traffic possessing burstiness, an elegant statistical reliability analysis framework in regard to latency is proposed based on martingale theory. The backlog martingale process is constructed. Leveraging stopping time theory, a tight upper bound of unreliability is obtained. An arrival abstraction and traffic allocation scheme is designed, which contributes to decouple the reliability requirement as the maximum supportable arrival load. Finally, we implement our Fasys system, and extensive experimental results show that our system can achieve consistent high-precision positioning and low-BER data communication for low-speed data services. And the proposed martingale-based traffic allocation scheme can achieve the provisioning of reliability in regard to the latency for high-speed data services.
Design and Characterization of a Burst Mode 20 Mfps Low Noise CMOS Image Sensor
Authors: Yue Xin , Fossum Eric R.
Published: July 2023

This paper presents a novel ultra-high speed, high conversion-gain, low noise CMOS image sensor (CIS) based on charge-sweep transfer gates implemented in a standard 180 nm CIS process. Through the optimization of the photodiode geometry and the utilization of charge-sweep transfer gates, the proposed pixels achieve a charge transfer time of less than 10 ns without requiring any process modifications. Moreover, the gate structure significantly reduces the floating diffusion capacitance, resulting in an increased conversion gain of 183 µV/e−. This advancement enables the image sensor to achieve the lowest reported noise of 5.1 e− rms. To demonstrate the effectiveness of both optimizations, a proof-of-concept CMOS image sensor is designed, taped-out and characterized.
Tourism, Value Appropriation, and Ecological Degradation
Authors: Liodakis George
Published: July 2023

This article highlights the main characteristics of the rapid development of tourism during recent decades, as well as the limitations of the existing literature concerning this development. An alternative (Marxist) theoretical framework is then developed for the explication of the development of commodified tourism, the role of ecological and cultural (value) appropriation in the determination of capitalist profitability, and its developmental implications. As argued, this value and resource appropriation and the exploitation/appropriation dialectic have adverse socioeconomic and ecological implications, while leading to the rapid growth of tourism against other sectors. On the other hand, the cultural homogenization and ecological degradation brought about especially by mass tourism imply a self-limiting development of tourism itself. Concluding that the current mode of tourism development is ecologically and socially unsustainable, we end with a broad outline of a different perspective of decommodified tourism within a post-capitalist development.
MATHEMATICAL MODELS OF THE DEPENDENCE OF THE STRUCTURAL AND DEFORMATION-STRENGTH PROPERTIES OF THE GYPSUM-WOOD COMPOSITE ON THE COMPONENT COMPOSITION
Authors: Lukuttsova N. , Pykin A. , Lukash A. , Shvachko S. , Krasnyy V.
Published: July 2023

The production of cement-wood composites (CWC) is difficult due to the presence of extractable substances in the wood filler, which have a negative effect on the hydration of cement, the shape and size of the resulting crystalline hydrates, and the setting time, which leads to a decrease in the strength characteristics of the CWC. Gypsum-wood composites (GWC), in contrast to CWC, are less sensitive to the effects of extractable substances, but they are characterized by low strength and deformability. In order to improve the structural and deformation-strength properties of the GWC, the article presents a mathematical modeling of the effect of the component composition on the average density, open porosity, compressive strength and modulus of elasticity of a gypsum-wood composite for the installation of partitions and enclosing structures in buildings for various purposes. Mathematical models of the dependence of GWC properties on the amount of building gypsum, urea-formaldehyde resin and wood filler from freshly cut hardwood are presented. According to Student's and Fisher's criteria, an assessment was made of the statistical significance and adequacy of the obtained mathematical models, which make it possible to determine the rational values of recipe factors in the manufacture and operation of GWC with an average density of 1250-1370 kg/m3, an open porosity of 25-36%, and a compressive strength of 25-30 MPa, modulus of elasticity 1210-1780 MPa.

El denso trabajo teórico respecto al ocio, al tiempo libre y a prácticas vinculadas a lo corporal se articula con la experiencia y lo recopilado desde el campo realizada en el grupo de running “La Cava”, la experiencia en la MaratónUNLP y el acceso y análisis de los datos de inscripción de los años 2018, 2019 y 2022, se suma a entrevistas en profundidad realizadas a informantes claves y a los datos de la Encuesta Nacional 2021 sobre Uso del tiempo realizada y publicada con acceso abierto por el Instituto Nacional de Estadísticas y Censos (INDEC, Argentina). La tesis representa un estudio longitudinal que explora al running como una práctica corporal que permite analizar la vinculación entre el uso del cuerpo y las clases medias, los estilos de vida y el tiempo de ocio, y es, a su vez, un trabajo que permite la actualización de la crítica al tiempo libre y ocio como un proyecto al que acceden, en potencia, las clases medias, y en donde se producen los procesos de distinción. Se concluye que si las personas manifiestan que cuando corren transitan estados de felicidad y, por lo tanto, pasar la meta se hace con una sonrisa, festejando y con los brazos en alto, quizás sea momento de pensar que todas las personas podrían tener derecho a transitar por experiencias similares.
Antipoverty programs : impact evaluation, externalities and limitations
Authors:   , Pacheco Barzallo Diana
Published: July 2023

This doctoral thesis utilizes diﬀerent microeconometric methods to estimate the direct impact, the generated externalities, and the limitations of two antipoverty programs implemented in Latin America in the form of Conditional Cash Transfers (CCT). I focus on CCT programs for two reasons. First, due to the important positive eﬀects shown, many governments have rapidly adopted this tool as their main initiative to fight poverty. And second, CCTs are one of the very few initiatives that were actually generated in the developing world and later imported in developed economies. The thesis is comprised of three separate, but closely related chapters. I perform empirical analyses using data from two programs in Mexico and Colombia, employing program evaluation techniques, as well as parametric regression modelling. The main contribution of this thesis is to show that social interventions, besides having important eﬀects on the targeted population, have also a great impact on people not part of the program. In fact, individuals respond to incentives, pushing a change in their decisions, either through monetary transfers, or by a change in the observed behavior of their peers. Thus, CCT programs can be expected to have an eﬀect beyond the targeted group. The externalities shown by CCT are mainly positive, specially when analyzing health, nutrition and educational outcomes. The results are less clear when analyzing labor outcomes. Nevertheless, as any policy, these programs are perfectible. It is important to identify these limitations, as well as the changes to the designs for future work.

“AN ANALYSIS OF IMPACT OF FOREIGNDIRECT INVESTMENT ON ASIAN STOCK MARKETS : WITH SPECIAL REFERENCE TO BSESENSEX AND SZSE COMPONENT INDEX"
Authors: B. Raval Vatsal , Kumar Chakrawal Alok
Published: July 2023

This research paper explores the influence of Foreign Direct Investment (FDI) on the Bombay Stock Exchange Sensitive Index (BSE SENSEX) in India and the Shenzhen Stock Exchange Component Index (SZSE) in China. By analysing the relationship between FDI and these stock market indices, the study aims to provide insights into the potential effects of foreign investment on their respective performances. Employing a quantitative methodology, the research utilizes yearly data from 2015-16 to 2021-22 to examine the dynamic interactions between FDI inflows and stock market indices. Preliminary findings indicate a high positive correlation between FDI and SZSE indices performance while in case of the BSE SENSEX there is a very little positive correlation with FDI. The results suggest that FDI inflows have an insignificant impact on these indices. In conclusion, this research contributes to the existing literature by examining the impact of FDI on the BSE SENSEX and SZSE indices. The findings provide valuable insights into the interplay between foreign investment and stock market performance, in the Indian and Chinese economies and contributing to the broader understanding of the Asian financial market.

Background- Cervicogenic headache is a unilateral headache felt in the occipital,temporal or orbital region and is a
common finding in patients suffering from neck pain, ranging from mild to severe in intensity.Several interventions are
effective in treating neck pain with headaches that focus on the muscles and joints of the posterior neck.The purpose of
this case report is to describe the efficacy of C1-C2 SNAG mobilization and deep cervical flexor muscle (DCFM)
strengthening in reducing cervicogenic headache. Case Description: This case report describes the effect of training
DCFM using a pressure biofeedback unit in addition to SNAG mobilization at C1-C2 in a 46-year-old female patient who
presented with cervicogenic headache post neck pain.Upon referral to physical therapy,she was treated for 6 sessions,
two sessions per week focusing on pain reduction,posture re-education,improving cervical range of motion,and muscle
strength. Outcome: Physical therapy intervention targeting DCFM using pressure biofeedback unit along with manual
therapy significantly reduced the patient's NPRS score from 8/10 to 3/10 within three weeks and further reduced it to 1/10
at three months and six months follow-up. Her headache duration changed from being constant to intermittent, lasting
only few minutes. Neck Disability Index changed from 40 to 18. Discussion & Coclusion: Combined intervention of
SNAG mobilization and DCFM training is effective in reducing pain in cervicogenic headache. This case report
concluded that both treatment intervention when used in combination can be employed as the mainstay treatment in
reducing frequency,intensity and duration of this condition.

Background : Intra operative pathological assessment has offered a very valuable service in patient management. The present study was done to evaluate the status of intraoperative cytology as a diagnostic and supportive investigation for various tumours. To evaluate the utility of imprint /scrape cytology for the rapid diagnosis of Aim and objectives: surgically removed specimens. 70 surgically removed specimens from various organs and Materials and Methods: systems were studied. Smears were taken from each specimen before formalin fixation and stained by modified rapid H&E and Papanicolaou staining. Cytological diagnosis was made and then results were compared with the histological diagnosis taking the latter as the gold standard. Out of the 70 cases sampled, 70 were satisfactor Results: y for evaluation. Overall accuracy rate was 87.14 % .Six cases of false positive diagnosis and 3 false negative diagnosis were made. Positive predictive value was 75% and negative predictive value was 93.47%. Imprint /scrape Conclusions: cytology is a good complement for the rapid diagnosis in histopathological study of tumor/tumor like lesions and intra operative cytology can be used an adjunct to frozen section.
The Future of Physical Education and Sports in Light of the Crisis of Playgrounds in Schools in the Republic of Djibouti

Published: July 2023

The teaching of Physical Education and Sports (PES) is increasingly compromised in Djibouti, as most of the new middle and secondary schools built in the past two decades do not have playgrounds. This situation has meant that some students have never had access to physical and sports activities as part of their school curriculum. They consequently suffer the detrimental consequences of this situation, particularly on health, well-being, and overall development. To carry out this research, we have analyzed several data sources, such as internal reports and statistical directories of the national education system. We have also studied legislative documents, articles, reports, and chapters on the evolution of school education in Djibouti, as well as ethnographic surveys. Through descriptive analyses, the purpose of this article is to highlight the disparities that exist among different schools in terms of playground equipment and, by extension, access to physical and sports activities. Ultimately, this article emphasizes the urgent need to address the crisis of playgrounds in schools to ensure a better future for PES and enable students to benefit from the physical, social, and educational advantages associated with engaging in physical and sports activities.

Modeling and simulation of pulp mill plant permanent magnet synchronous machines (PMSM) with damper windings using Matlab/Simulink is presented. Pulp mill is a manufacturing facility that converts wood chips, timber, wood products into wood pulp that is used to produce paper, cardboard, thick fiber board, which can be used by a paper mill for further processing. Pulp and paper industry has been considered a large consumer of energy and constitute a native treat to the plant as a result of machines transient due to heavy load variation. Modeling and simulation of pulp mill plant (PMSM) with damper windings show the behavior of machines virtual image environments to test the performance, stability and safety for less cost. It helps the pulp mill plant designers, engineers and technicians to understand the process of creating and analyzing machines model and predict its performance in the real world. Damper winding is an additional property added in pulp mill plant PMSM to damping out any oscillation that may cause any sudden changes in the load on the rotor when in synchronism. It prevents hunting and provides starting torque and dose not requires machines spinning. The rotor field lags the stator by which the load angle changes as a result of load variation. Permanent magnet synchronous machine (PMSM) is an alternating current (ac) machine whose excitation is provided by the permanent magnet. It has permanent magnet (PM) on the rotor and windings on the stator. PMSM does not have field windings on the stator frame instead, it relies on the magnets to provide the magnetic field against which the rotor interacts to produce a torque. Pulp mill plant PMSM with damper windings was modeling and simulated using Matlab/Simulink as presented in this paper. The electrical and mechanical equations of various steps ware developed in state space form from which the SIMULINK models were built with pulp mill plant PMSM with damper windings using the block-approach method with in-built Matlab/SIMULINK to obtained results for dynamics performance, controllability, stability study and is widely used in the engineering, manufacturing, physical sciences, product development and recommended for pulp mill plant designers, engineers, technicians and plant operators.
