Published: October 2022

Abstract
We describe a wireless RF network for capturing event-driven data from thousands of spatially distributed sensors. As asynchronous devices, each sensor detects events within its local environment. Information acquired by the full network can enable prediction of the time evolution of the system, whether a brain or cardiac circuit in the human body, or an assistive living environment, for example. We develop a communication concept inspired by principles of synaptic information processing in the brain which we mimic by a code-division multiple access strategy in a sparse network. Through extensive simulation, we optimize wireless transmission from ensembles of event-detecting sensors for efficient use of the power and spectrum at low error rates, which is then implemented on-chip to demonstrate the core communication scheme in silico. We also apply the concept to recordings from thirty thousand neurons in the primate cortex, to decode and predict forward state trajectories for hand movement.

AbstractBackground Undernutrition among adolescent girls is a major public health problem. Despite the adolescence period being a unique opportunity to break the intergenerational cycle of malnutrition, in Ethiopia, particularly in the study area information regarding the nutritional status of adolescent girls is lacking. Therefore, this study aimed to fill this identified gap. Objective To assess the prevalence of undernutrition and associated factors among rural adolescent girls in Daramalo district, Southern Ethiopia. Methods: A community-based cross-sectional study was conducted among 672 adolescent girls from March 11 to April 11, 2021, using a systematic random sampling technique. Anthropometric measurements were analyzed by WHO Anthro plus software for Z-score. The data were entered into Epi data version 3.1 and analyzed with SPSS window version 25.0. Binary logistic regression analysis was used to identify factors associated with undernutrition. Adjusted odds ratio (AOR) and 95% confidence intervals (CI) were used to measure the strength of association and a p-value less than 0.05 was used to declare the level of statistical significance. Results The prevalence of thinness and stunting was 12.6% (95%CI: 10.3%, 15.2%) and 21.1% (95%CI: 18.3%, 24.3%), respectively. Large family size (AOR = 3.23; 95%CI: 1.87, 5.58), ≤ 2 meal frequency (AOR = 3.21; 95%CI: 1.59, 6.45), being non-menstruating (AOR = 4.24; 95%CI: 2.36, 7.61), poor and medium wealth index (AOR = 2.34; 95%CI: 1.15, 4.72) and (AOR = 3.16; 95%CI: 1.61, 6.21), and inadequate dietary diversity (AOR = 2.23; 95%CI: 1.34, 3.68) were factors significantly associated with an increased odds of thinness. Whereas, early adolescence (AOR = 1.54; 95%CI: 1.04, 2.28), large family (AOR = 1.85; 95%CI: 1.24, 2.77), separate decision making on nutrition service by father or mother, (AOR = 3.21; 95%: 1.68, 6.14) and (AOR = 3.01; 95%CI: 1.76, 5.15), inadequate dietary diversity (AOR = 2.12; 95%CI: 1.41, 3.19), and household food insecurity (AOR = 2.24; 95%CI: 1.48, 3.41) were factors significantly associated with an increased odds of stunting. Conclusions Stunting and thinness were found to be high in the study area. Future interventions and programs may consider strategies to improve dietary diversity, food security, wealth status, household decision-making power, meal frequency, and family size through increasing the awareness of the community on the intergenerational effect of adolescent undernutrition and by strengthening community-based adolescent nutrition programs.
Genetic Dysregulation of Immunologic and Oncogenic Signaling Pathways Associated with Tumor-intrinsic Immune Resistance: A Molecular Basis for Combination Targeted Therapy-Immunotherapy for Cancer
Authors: Hargadon Kristian Michael 
Published: October 2022

Abstract
Since the turn of the century, advances in targeted therapy and immunotherapy have revolutionized the treatment of cancer. Although these approaches have far outperformed traditional therapies in various clinical settings, both remain plagued by mechanisms of innate and acquired resistance that limit therapeutic efficacy in many patients. With a focus on tumor-intrinsic resistance to immunotherapy, this review highlights our current understanding of the immunologic and oncogenic pathways whose genetic dysregulation in cancer cells enables immune escape. Emphasis is placed on genomic, epigenomic, transcriptomic, and proteomic aberrations that influence the activity of these pathways in the context of immune resistance. Specifically, the role of pathways that govern interferon signaling, antigen processing and presentation, and immunologic cell death as determinants of tumor immune susceptibility are discussed. Likewise, mechanisms of tumor immune resistance mediated by dysregulated RAS-MAPK, WNT, PI3K-AKT-mTOR, and cell cycle pathways are described. Finally, this review brings attention to the ways in which genetic dysregulation of these immunologic and oncogenic signaling pathways are informing the design of targeted interventions to restore immune susceptibility of cancer cells and enhance immunotherapeutic efficacy through combination targeted therapy-immunotherapy regimens that overcome the resistance mechanisms known to limit the success of monotherapies.
WITHDRAWN: Microplastic accumulation in aquatic insects of different feeding guilds collected from wastewater in Sohag Governorate, Egypt
Authors: ali  
Published: October 2022

Abstract
Microplastics (MPs) have been detected in many freshwater organisms because of increasing plastic contamination within the freshwater environment. However, the correlation between MPs in organisms and their surrounding environment still needs studies. This study investigates MP contamination in one of the wastewater ponds east of Sohag Governorate, Egypt. Four common freshwater insect families representing different feeding guilds were employed to detect MPs contamination.
Revisit the performance of Doppler positioning with LEO satellites
Authors: Shi Chuang , Zhang Yulu , Li Zhen 
Published: October 2022

Abstract
Recently, the Doppler shifts from Low Earth Orbit (LEO) satellites have been used to augment GNSS and provide standalone positioning, navigation and timing services in opportunistic navigation frameworks or GNSS-like navigation systems. In this paper, we proposed a Doppler-only point-solution algorithm for GNSS-like navigation systems operated in LEO. In these systems, LEO satellites are assumed to be modified to support navigation capabilities. Their positions, velocities and clock drifts could be obtained from ephemeris. The proposed point-solution algorithm can estimate the receiver clock drift, position and velocity simultaneously. Then, the main error sources in Doppler positioning are analyzed. As one of the main error sources, satellites’ position error of several meters and velocity error of several centimeters per second would reduce the positioning performance significantly. The LEO doppler positioning accuracy will deteriorate if there are no error corrections for the ionospheric and tropospheric delay rates. Subsequently, the performance of Doppler positioning algorithms is analyzed. The Zero-Difference Doppler positioning accuracy is in meter-level, which is comparable with pseudorange-based positioning in GNSS. By doing difference between satellites, the receiver clock drift is eliminated and the Between-Satellite-Difference Doppler positioning accuracy is improved by about 10% as Doppler Dilution of Precision is reduced by 12.3%. Moreover, we analyzed the sensitivity of initial position error in the LEO-based Doppler positioning and found that the initial position error should be less than 300 km to ensure convergence.

Abstract
The blending of π-conjugated molecules with polymeric semiconductors is an effective strategy to promote the charge carrier mobility because of the transmission path by the conductive polymers through electrical bridge connection of the small organic molecule crystalline domain. In this work, pentacene single crystal was prepared to induce the molecular orientation of polymeric semiconductor PDPP2T-TT-OD, which led to an enhanced field-effect mobility of the organic thin-film transistor (OTFTs) by improving the crystallinity due to nucleation and growth phase separation. Besides, with the addition of anti-solvents, the crystallization of the blend film was further improved, 27 times higher than that of a pure polymer semiconductor-based OTFTs. That was because the pentacene nuclei induced polymer crystallization through π-π interactions and the addition of antisolvent promoted the aggregation of polymer chains in solution, enabling the molecular chains packed more closely in solid films. Therefore, the chain arrangement of polymers induced via small molecular single crystals provides a new idea to improve mobility in composite semiconductor thin films for the construction of novel organic optoelectronic devices.

Abstract
The wide application of polysaccharide-based aerogel is limited by its hydrophilicity. To solve this problem, sodium alginate/ sodium carboxymethyl cellulose (SA/CMC) with silica nanoparticles and methyl trimethoxysilane as hydrophobic modifiers was prepared in this study. The sodium alginate (SA) and sodium carboxymethyl cellulose (CMC) were selected because of their low cost and easy of combination with the other two materials. After the silane reagent modification, Ca2+ crosslinking, surface plasma treatment, thermochemical vapor deposition and freeze-drying methods, the aerogel get density of 0.080 g/cm3, high porosity of 94%, three-dimensional porous structure with great adsorbed ability. This superhydrophobic SA/CMC aerogel exhibits excellent water stability, appropriate compressive strength and good adsorption capacity of cationic dye methylene blue (MB). And the adsorption process is analyzed by adsorption kinetics. Meanwhile, this aerogel gets great absorbency and efficiency towards varieties of organic solvents, which gives it great potential of being used in the field of oil-water separation, textile dye wastewater treatment, etc. Moreover, this aerogel is expected to be recycled after washing.

AbstractDue to its wide distribution, the long-distance oil and gas pipeline will inevitably pass through the landslide risk area. And pipeline landslide disaster has become one of the biggest threats to pipeline safety because of its multiple. The field monitoring method is time-consuming and expensive, and the probability of monitoring the whole process of landslide pipeline disaster is extremely low, and these problems can be effectively solved by physical models. A large physical simulation platform of oil and gas pipelines influenced by landslide geological disasters was designed and established. Under different dip angles of landslides was conducted, and the changes of stress and strain pipeline, and soil displacement during the test process were monitored and analysed. The experimental results show: (1) the bending process of the pipeline can be divided into slow-bending stage, constant-speed bending stage, and accelerated-bending stage. (2) The tensile strain is produced back to the impact direction of landslide; the compressive strain is produced facing the direction of landslide. (3) When the pipeline is in the accelerated-bending stage, the pipeline stress presents a linear and rapid increasing state, and rebounds occurs after reaching the maximum. (4) At the centre of the pipeline, the strain difference between back and facing the direction of landslide increases continuously. These experimental results have obtained the pipeline deformation law in the whole process of pipeline landslide disaster, which can provide great help for the monitoring and early warning of pipeline landslide disasters on site.
Precise measurement for 3D laser scanner with large range
Authors: Sheng Wei-wei 
Published: October 2022

Abstract
High precision and large measurement range are the target of any one three-dimensional scanner. For a laser scanner, measurement precision depends on its calibration results, i.e. determining mathematical expression of the light plane in camera coordinate system. However, as calibration results are locally optimal solutions, high precise measurement in a large range is difficult. In this paper, we give a precise measurement method and the corresponding calibration procedure for a laser scanner with a large measurement range. With the help of a linear translation stage and a planar target, functions which gives the relationship between center point of the laser stripe and the perpendicular/ horizontal distance are obtained. Once image of light stripe is captured, we can get a precise measurement result from the normalized feature points. Compared with a traditional measurement method, distortion compensation is not necessary and precision of measurement is improved significantly. Experiments show that root mean square error of measurement results according to our proposed method is reduced by 64.67% related to the traditional method.

Published: October 2022

Abstract
Bulk solids stacking in terminals, ships, trains and other bulk solids storage yards is always challenging considering the requirements of the optimal utilization of the storage area. In this study, the stacking shapes of a variety of bulk solids with different particle sizes were tested, and the curved shapes of the stockpiles were extracted to establish the actual three-dimensional models of the bulk solids accordingly. The three-dimensional curved stockpiles were used to design the bulk solids stacking strategy where the bulk stacking locations, the stacking volume and the flatness of stacking were optimized. A modified golden section method with a self-influenced factor was developed to improve the calculation efficiency of the stacking algorithm for bulk solids stacking flatness. Furthermore, the bulk solids stacking strategy and algorithm were verified by experiments. The results showed that the curved three-dimensional models were very close to the actual shapes of the bulk solids stockpiles while the improved golden section method was more accurate and efficient than the traditional golden section method in finding the optimal values of the stacking volumes for flatness. For different bulk solids tested, the experiment results showed that good flat stacking can be achieved by the developed stacking strategy.

Abstract
Purpose
The safety of an MRI simulation-guided boost after short-course preoperative radiotherapy (SCPRT) for unresectable rectal cancer is assessed with a planned interim analysis.
Methods and materials
Patients diagnosed with clinical stage T3-4 or regional lymph node-positive disease with positive mesorectal fascia (MRF) or T4b disease evaluated by pelvic MRI were randomly assigned to the SCPRT-boost group (25 Gy over 5 fractions plus 4 Gy delivered to the gross tumor volume, followed by four cycles of chemotherapy) or preoperative chemoradiotherapy group (50 Gy over 25 fractions with concurrent chemotherapy). Then, patients received total mesorectal excision surgery after preoperative treatment. The primary endpoint was the R0 resection rate. The interim analysis was performed when 42 patients completed their assigned treatments.
Results
From October 2018 to November 2019, a total of 43 patients were enrolled, and 42 patients were included in the interim analysis. During preoperative therapy, grade 3 or above toxicities were observed in 10/21 (47.6%) patients in the experimental group, and 4/21 (19.0%) patients in the control group. A total of 17 (81.0%) and 13 (61.9%) patients in the experimental group and control group underwent surgery, respectively. Overall, 69.7% of the patients achieved R0 resection or clinical complete response (cCR) in the intention-to-treat analysis. Surgery-related adverse complications were observed in 2 patients (11.8%) in the experimental group and 1 patient (7.7%) in the control group.
Conclusion
Our results show that the toxicity of an MRI simulation-guided boost dose after short-course preoperative radiotherapy (SCPRT) for unresectable rectal cancer is acceptable. Thus, this clinical trial will be continued as planned.
A variational derivation of Stoney-like formulas for self-stressed bilayered plates
Authors: DiCarlo Antonio , Rizzoni Raffaella , Paroni Roberto 
Published: October 2022

Abstract
Since the beginning of the 20th century, it is known that the spontaneous bending of heterogeneous bilayered plates correlates with the self-stress due to the contrast in the material properties of the two layers, and that this correlation can be exploited to gauge the internal stress state. Over the last decades, ever-growing device miniaturization has made stress assessment and even stress engineering an area of major technological interest. In this paper, we obtain two effective 2D models accounting for the spontaneous bending of devices comprised of a thin substrate and a much thinner coating by applying a Gamma-convergence technique to the standard 3D linear hyperelastic model of a bilayered plate. Our procedure is characterized by the introduction of two distinct smallness parameters plus three independent energy scaling parameters.

Abstract

Marine macroalgae are nutraceuticals rich in nutritional profile and secondary bioactive metabolites. However, they have varied nutritional and biochemical qualities due to a variety of reasons. This study aimed to determine the phytochemical profile and biological activities of Caulerpa racemosa, edible green algae also known as Sea grapes. The study successfully identified secondary metabolites through metabolomic profiling untargeted by LC-HRMS as well as a bioactive peptide. In addition, antioxidant activity and cytotoxicity of extracts and compounds were determined. A total of 103 metabolites were identified in C. racemosa extract obtained by the maceration, while 48 were detected in the soxhlet extract. A peptide with the sequence ELWKTF (Glu-Leu-Trp-Lys-Thr-Phe; C41H58N8O) and its abundance was identified in the α-chymotrypsin hydrolysate of C. racemosa. In the antioxidant activity test, Soxhletated-extract (ES) and purified fraction 1 (PF1) had half-maximal effective concentration (EC50) < EC50 of control/GSH (DPPH inhibition) and PF1 had EC50 < EC50 of control/Trolox (ABTS inhibition). The cytotoxicity results showed that macerated-extract (EM), ES, and PF1 as antioxidant agents in the observed EC50 were safe. In general, C. racemosa contains antioxidant nutrients, metabolites, and bioactive peptides, a factor that makes it a promising functional food and pharmaceutical.

Published: October 2022

Abstract
Background
Self-evaluation, as an expression of self-concept, becomes increasingly complex in adolescence. Parental bonding, personality traits, and psychological status were the three main determining factors of adolescents’ self-evaluation. We aimed to tested associations through a systematic approach.
Methods
Data were from the 2014 Chinese Family Panel Studies (CFPS). The association of parental bonding (measured by the Parental Bonding Instrument), personality traits (the Responsibility Scale), and psychological status (the Kessler Psychological Distress Scale) with self-evaluation measured in three domains (the Rosenberg Self-Esteem Scale, the Nowicki- Strickland Locus of Control Scale for children and the Self-Discipline Scale) were tested by the structural equation modeling (SEM) analysis.
Results
A total of 892 Chinese adolescents were included. Significant positive correlations were found among self-evaluation, parental bonding, personality traits, and psychological status. The overall (direct and indirect) effect of parental bonding on adolescents’ self-evaluation was 0.49. Personality traits and psychological status were directly associated with adolescents’ self-evaluation.
Conclusion
The use of SEM offered a detailed analysis of the correlations between parental bonding, personality traits, and psychological status and a systematic approach to investigate their direct and indirect effects on adolescents’ self-evaluation. The three factors directly associated with adolescents’ self-evaluation and parental bonding indirectly affected adolescents’ self-evaluation that was mediated by both personality traits and psychological status.
