Relationship between bow stability and postural control in recurve archery
Authors: Sarro Karine Jacon , Viana Thaynã De Castro , De Barros Ricardo Machado Leite 
Published: April 2020

AbstractArchery is a sport that requires fine movement control, and postural stability is considered an important variable to achieve high performance. In order to better understand the coupling between archer and bow during the aiming phase, the aim of this study was to investigate the relationship between bow stability and postural control in recurve archery according to shooting performance. A total of 8 archers shot 6 arrows at a 13‐m distant target. The three‐dimensional position of one marker attached to the bow and the center of pressure (COP) position of the archer (the point of application of the resultant ground reaction force on a force plate) were measured during the aiming phase, representing bow and archer displacement, respectively. COP displacement in the direction across the target (COPY), length of the COP trajectory (DCOP) and length of the bow trajectory (Dbow) were higher in the lowest scoring shot compared to the highest one. A strong and significant correlation was found between COP and bow displacement in the direction towards/away from the target (COPX and DX) and between COPX and vertical displacement of the bow (DZ) during the highest scoring shot. This result indicates that synchronization between body and bow sway may influence the accuracy of the shot, suggesting that combined balance and bow stability training exercises would be beneficial to improve archery performance.
Directly coupled adiabatic superconductor logic
Authors: Takeuchi Naoki , Arai Kota , Yoshikawa Nobuyuki 
Published: April 2020

Abstract
Adiabatic superconductor logic (ASL) families are energy-efficient because they can operate with a switching energy much less than the I
cΦ0 product, where I
c is the critical current for Josephson junctions, Φ0 is the flux quantum, and I
cΦ0 is generally on the order of 10–19 J. A switching energy of 0.03I
cΦ0 has been demonstrated by adiabatic quantum-flux-parametron (AQFP) logic, which indicates the possibility of extremely energy-efficient digital circuits using ASL. ASL uses signal transformers to propagate and invert the signal current; otherwise, it is difficult to design inverters. However, signal transformers are generally difficult to miniaturize. Therefore, to realize high-density and energy-efficient superconductor circuits, ASL that does not use signal transformers is required. In this paper, we propose ASL without signal transformers, which we call directly coupled quantum-flux-parametron (DQFP). DQFP logic is based on AQFP, but it can invert signal current without using signal transformers. We conducted numerical simulation of a DQFP inverter chain to show that DQFP logic can invert signal current without signal transformers, and that DQFP logic can operate adiabatically. Then, we designed and fabricated basic DQFP circuits, such as an inverter chain and a full adder. All the circuits were found to have wide operating margins. Our results indicate that DQFP logic is suitable for high-density and energy-efficient superconductor circuits.

Abstract

Saccharum officinarum L. bagasse is waste from sugarcane plants contains lignin, hemicellulose, cellulose and wax compounds. Isolation of cellulose from sugarcane can be done by acid hydrolysis of sugarcane waste and delignification with Sodium Hydroxide (NaOH). The objectives of this research were to study the effect of acid type and concentration on the physical and chemical characteristics of cellulose isolated from sugarcane bagasse. The acid variation that used were nitric acid: sulphuric acid; nitric acid; hydrochloric acid and sulphuric acid: hydrochloric acid in 1:1; 2:1 and 3:1 in the variation of concentration for each combination. Cellulose characteristics observed were color, shape and powder properties such as Hausner Ratio, Carr’s index, Angle of Repose and functional group analysis of cellulose using FTIR (Fourier Transform Infrared). The cellulose that isolated from sugarcane bagasse with HNO3: H2SO and HNO3: HCl were matched in white powder form with standard cellulose. Cellulose color that obtained with other acids were cream in fiber form. The results showed that the hydrolysis process of cellulose with nitric acid was more effective than sulfuric acid and hydrochloric acid. Standard cellulose FTIR spectra showed that delignification process was success and cellulose obtained from sugarcane bagasse. Sugarcane bagasse cellulose samples that isolated with nitric acid: hydrochloric acid (2:1) was the largest in percentage of cellulose (44.143%) and showed in line peaks with standard cellulose. Bulk Densities, Tapped Densities, Hausner Ratio, Carr’s index and Angle of Repose values of sugarcane bagasse cellulose isolated in sequence were 0.05; 0.07; excellent; 26.6; good.

Abstract
A preliminary study of the site-specific inorganic fertilization on lowland rice was carried out in Jambu village, Burneh District Bangkalan Regency East Java Province from March to July 2014. The experiment used a factorial split-plot design, with 5 replications. As the main plot were two varieties of lowland rice namely Inpari 4 and Inpari 10; and as a subplot was fertilization (dose level/inorganic type) based on a. existing practices (250 kg Urea + 300 kg NPK Ponska + 100 kg SP-36) b. PSTK (300 kg Urea + 75 kg SP-36 + 150 kg NPK), c. PC (150 kg Urea + 350 kg Ponska) and d. SSNM (125 kg Urea + 300 kg Ponska). The observations showed that there was no interaction effect between varieties and fertilization to the plant growth and yield. These parameters were affected significantly only by fertilization treatment. The highest weight of plotting yield and harvest yield was obtained in the fertilizer treatment of 453.62 kg/6.25 m2 and 7.26 tons’ ha−1. Thus the use of assistive devices, especially the PSTK and SSNM applications were more efficient in the use of inorganic fertilizers with the yields equivalent to the existing practice by the farmers.

Abstract
Moslems are required to remain consistent in wearing syar’i clothing. Sometimes, however, it is very difficult to distinguish between syar’i clothes and the non-syar’i ones, especially in the current millennial era and until the end of time there are many temptations that are not good. Digital image processing in the present day has become one of the areas that can be processed to help various problems associated with images. However, it requires very long processing time and ineffective processing. The CPU alone is not enough. Therefore, it takes processing time allocation that can cut the time to speed up the process. This study utilizes the way to speed up performance analysis of digital images through GPU. The performance analysis of GPU includes CUDA and Yolo because it allows specialists in parallel programming to use GPU resources and can perform the object detection process quickly and accurately by applying an artificial neural network to the image of someone who is wearing syar‘i hijab as smart clothes for Moslem women. Several hardware, software, and file dependency specifications are employed to support the implementation process. The test results achieve the accuracy of 100%, proving that by using the implementation of Yolo under GPU.

Authors: Karthik N. B. , Bal Krishna KC , Sathasivan Arumugam 
Published: April 2020

Abstract
Chloramine is used as a secondary disinfectant in water distributions system (WDS). However, nitrification is a major concern involved in the chloraminated WDS as it leads to the accelerated decay of chloramines. After the onset of nitrification, breakpoint chlorination followed by rechlorination is generally practiced in WDS to reinstate chloramine residuals in the WDS. In this study, two different control strategies re-chlorination and breakpoint chlorination followed rechloramination were applied on the severely nitrified water collected from the laboratory-scale reactor system. Results showed that breakpoint chlorination followed by rechloramination is highly stable as the chloramine residual was maintained up to 300 hours and is highly effective than rechlorination alone as it could maintain residue only up to 50 hours even with repeated re-dosing.

Abstract
The intelligent distribution network is an important hub for connecting power generation and users, and the security of its information is closely related to the stable operation of the power grid. In order to solve the contradiction between the security and real-time of information in intelligent distribution network according to Supplementary Provisions for Safety Protection of Medium and Low Voltage Distribution Network Automation System, an information security model of intelligent distribution network is proposed, after deeply studying AES encryption algorithm and SHA-256 authentication algorithm, using OPNET as simulation software for smart distribution network information to carryout transmission delay curve. FPGA is used as information security processing platform. We obtain the total delay, analyze the integrity and availability. The experiment proves that the intelligent distribution network information security processing solution satisfies the three elements of CIA information security, and has good confidentiality, integrity and availability.

Abstract
A parabolic trough collector was subject of a thermal study considering heat exchange mechanisms involved in the conversion process of solar energy into heat. The physical model presented was developed with assumptions related to steady state conditions. A code, developed under Matlab, allowed to estimate, by an iterative calculation, all temperatures encountered in the studied system and to calculate, consequently, various efficiencies: optical, energetic and exergetic. After validation of the model, a parametric analysis was carried out in order to consider the influence of the main model parameters on the exergetic behavior of the solar system.

Abstract
We studied the magnetic properties of polycrystalline Y3Fe5O12 (YIG) thin films (less than 100 nm) deposited on thermally oxidized silicon wafer by magnetron sputtering and followed by the post-annealing process. Our ferromagnetic resonance (FMR) results demonstrate that sputtering at room temperature combined with the post-annealing treatment can be an efficient method to achieve large-area (inch scale) and highly uniform YIG thin films with a low damping constant
α
∼ 7 × 10−3 on cheap oxidized Si wafer. Furthermore, our spin pumping experiments demonstrate that the polycrystalline YIG/Pt system has a good spin mixing conductance, where spin current can be effectively injected into the adjacent Pt layer from YIG through the interface. Then the electrical detection of magnetic properties (e.g., spin waves) of insulating YIG film can be achieved via the inverse spin Hall effect of Pt. The electrical detection of spin waves in the large-area polycrystalline YIG/Pt on silicon wafer may help to develop new spintronic devices (e.g., magnon-based devices) by utilizing the complementary metal-oxide-semiconductor (CMOS) technology.

Published: April 2020

AbstractBackgroundGlaucoma is the most frequent cause of irreversible blindness worldwide. There is no cure, but early detection and treatment can slow the progression and prevent loss of vision. It has been suggested that artificial intelligence (AI) has potential application for detection and management of glaucoma.Sources of dataThis literature review is based on articles published in peer-reviewed journals.Areas of agreementThere have been significant advances in both AI and imaging techniques that are able to identify the early signs of glaucomatous damage. Machine and deep learning algorithms show capabilities equivalent to human experts, if not superior.Areas of controversyConcerns that the increased reliance on AI may lead to deskilling of clinicians.Growing pointsAI has potential to be used in virtual review clinics, telemedicine and as a training tool for junior doctors. Unsupervised AI techniques offer the potential of uncovering currently unrecognized patterns of disease. If this promise is fulfilled, AI may then be of use in challenging cases or where a second opinion is desirable.Areas timely for developing researchThere is a need to determine the external validity of deep learning algorithms and to better understand how the ‘black box’ paradigm reaches results.

Published: April 2020

Abstract
African American (AA) women have an excess breast cancer mortality than European American (EA) women. To investigate the contribution of tumor biology to this survival health disparity, we compared gene expression profiles in breast tumors using RNA sequencing data derived from 260 AA and 155 EA women who were prospectively enrolled in the Southern Community Cohort Study (SCCS) and developed breast cancer during follow-up. We identified 59 genes (54 protein-coding genes and 5 long intergenic non-coding RNAs) that were expressed differently between EA and AA at a stringent false discovery rate (FDR) &lt; 0.01. A gene signature was derived with these 59 genes and externally validated using the publicly available Cancer Genome Atlas (TCGA) data from180 AA and 838 EA breast cancer patients. Applying C-statistics, we found that this 59-gene signature has a high discriminative ability in distinguishing AA and EA breast cancer patients in the TCGA dataset (C-index = 0.81). These findings may provide new insight into tumor biological differences and the causes of the survival disparity between AA and EA breast cancer patients.
