Development of a safety-aware intrinsically passive controller for a multi-DOF manipulator

In contexts where robots share their workspace with humans, safety is of supreme importance. Consequently, in recent years, a big impulse has been given to the design of human friendly robots by involving both mechanical and control design aspects. When it comes to controller design, this often involves introducing compliance and ensuring asymptotic stability using an interaction control scheme and passivity theory. Moreover, when human operators physically interact with the robot during work, strict safety measures become necessary with some of these including power and force limitations. In this thesis, a novel impedance control technique for collaborative robots is presented. The featured controller allows safe human-robot interaction by defining energy and power based safety metrics. An energy tank system is incorporated to this controller, in order to assure passivity of the overall system. The effectiveness of the proposed controller is evaluated with a KUKA robot arm in a co-manipulation environment.
Porphyra tenera Protects against PM2.5-Induced Cognitive Dysfunction with the Regulation of Gut Function

To evaluate the biological effects of Porphyra tenera (P. tenera), we tried to confirm the possibility that the intake of P. tenera could modulate cognitive and intestinal functions in PM2.5-induced cognitive decline mice. P. tenera attenuated PM2.5-induced learning and memory impairment through antioxidant and anti-inflammatory effects by regulating the mitochondrial function and TLR-initiated NF-κB signaling. In addition, P. tenera effectively alleviated Aβ production/tau phosphorylation by inhibiting the JNK phosphorylation. Also, the bioactive constituents of P. tenera determined the sulfated galactan, mycosporine-like amino acids (MAAs), and chlorophyll derivatives. Moreover, the bioactive compounds of P. tenera by gut fermentation protected against gut dysbiosis and intestinal tight junction damage with a decrease in inflammatory response and short-chain fatty acid production. Based on these results, our findings suggest that P. tenera with sulfated galactan and MAAs is a potential material for cognitive function improvement.
The use of a fuzzy neural network to determine the information content of factors affecting the implementation of the grip properties of a road with a tire

The task of assessing the traction of the road and tires is one of the most relevant in the technical examination of road accidents, as the results of its solution directly affect the assessment of the effectiveness of braking of wheeled vehicles, as the main method of preventing road accidents on motor transport. In the presence of such damage to the vehicle, which makes it impossible to conduct road tests, the expert has to use outdated calculation methods. This contributes to errors and increases the uncertainty of the data on which expert opinions are formed.The paper proposes ways to improve existing approaches to estimating the adhesion factor and indicators of braking efficiency of vehicles in the automotive examination of accidents in the presence of compositional (stochastic and fuzzy) uncertainty. Analysis of the use of mathematical methods in the practice of accident investigation showed that in the absence of the possibility of using traditional mathematical methods based on the detection of accurate quantitative relationships, to study accidents in uncertainty, it is advisable to use approximate modeling methods based on fuzzy (continuous) logics. The results of the study of the braking efficiency of vehicles of category M1 in operating conditions and the results of the evaluation of the informativeness of the factors influencing the adhesion factor, using the Fuzzy Logic Toolbox of the Matlab computing environment were used to the choice and substantiation of the method of estimating the coupling qualities of car tires in the study of road accidents in conditions of uncertainty. As a result, it was found that the improvement of existing approaches to estimating the adhesion factor and efficiency of vehicle braking in autotechnical examination of road accidents in the presence of compositional uncertainty can be achieved through the use of simple ANFIS models that provide better generalizing properties
Predicting Patient Length of Stay in Australian Emergency Departments Using Data Mining

Length of Stay (LOS) is an important performance metric in Australian Emergency Departments (EDs). Recent evidence suggests that an LOS in excess of 4 h may be associated with increased mortality, but despite this, the average LOS continues to remain greater than 4 h in many EDs. Previous studies have found that Data Mining (DM) can be used to help hospitals to manage this metric and there is continued research into identifying factors that cause delays in ED LOS. Despite this, there is still a lack of specific research into how DM could use these factors to manage ED LOS. This study adds to the emerging literature and offers evidence that it is possible to predict delays in ED LOS to offer Clinical Decision Support (CDS) by using DM. Sixteen potentially relevant factors that impact ED LOS were identified through a literature survey and subsequently used as predictors to create six Data Mining Models (DMMs). An extract based on the Victorian Emergency Minimum Dataset (VEMD) was used to obtain relevant patient details and the DMMs were implemented using the Weka Software. The DMMs implemented in this study were successful in identifying the factors that were most likely to cause ED LOS > 4 h and also identify their correlation. These DMMs can be used by hospitals, not only to identify risk factors in their EDs that could lead to ED LOS > 4 h, but also to monitor these factors over time.
Prevalence and Predictors of Scoliosis and Back Pain in 591 Adolescents: A Randomized, Stratified, Cross-Sectional Study in Riyadh, Saudi Arabia

Purpose Owing to the difficulty of establishing a screening program for scoliosis and back pain, along with their disabling consequences and the lack of local prevalence rates, we sought to study the prevalence of scoliosis and back pain in adolescents in Saudi Arabia and the burden reported by the affected age group on the health system. Materials and methods A school-based, cross-sectional pilot study covering all school districts in Riyadh, Saudi Arabia, was conducted. Students between 12 and 18 years of age were included. Students with any spinal or neurological disorders were excluded. Physical examinations to screen for scoliosis and student-filled questionnaires to assess back pain and health-related quality of life were performed. Results Of the 700 students, 591 met the inclusion criteria. High suspicion of adolescent idiopathic scoliosis (AIS) was considered in 174 students (29.44%). In addition, 45.42% of the students had a history of back pain. The Oswestry Disability Index showed that 87 students had disabilities. The average Scoliosis Research Society-22 score was 3 out of 5. A significant difference was found in the self-image and mental health domains for AIS (p = 0.04, p = 0.02, respectively). Age showed a significant increase in the odds ratio of a positive physical exam for every increase of one year in age (p < 0.01). Conclusion Identifying the prevalence rates and early associated factors during adolescence would help lower the burden on the health system and benefit public health in general. A nationwide study is required to identify the relationship between scoliosis and back pain.
N-Heptane Pool Fire Suppression with Twin-Fluid Water Mist

As one of the most promising halon alternatives, the merits of water mist have been demonstrated by prior research and tests. Much research done before has been focusing on the improvement of some aspects of water mist systems such as the shape of nozzle, the size of mist particles, and the additive used etc. In order to study the effectiveness of twin-fluid water mist technology and the role of nitrogen in fire suppression, a series of n-heptane pool fire suppression tests were carried out in this paper. The parameters such as fuel mass loss, flame temperature above the centerline of the pool, and axial heat fluxes were measured for assistant analysis of fire suppression during the tests as well as the fire video recorded. All suppression times were analyzed statistically based on the video and they all were under 30 seconds. Results show that the higher Nitrogen pressure is, the less the suppression time is, which means better suppression effect.
Physical Stimulation Combined with Biomaterials Promotes Peripheral Nerve Injury Repair

Peripheral nerve injury (PNI) is a clinical problem with high morbidity that can cause severe damage. Surgical suturing or implants are usually required due to the slow speed and numerous factors affecting repair after PNI. An autologous nerve graft is the gold standard for PNI repair among implants. However, there is a potential problem of the functional loss of the donor site. Therefore, tissue-engineered nerve biomaterials are often used to bridge the gap between nerve defects, but the therapeutic effect is insufficient. In order to enhance the repair effect of nerve biomaterials for PNI, researchers are seeking to combine various stimulation elements, such as the addition of biological factors such as nerve growth factors or physical factors such as internal microstructural modifications of catheters and their combined application with physical stimulation therapy. Physical stimulation therapy is safer, is more convenient, and has more practical features than other additive factors. Its feasibility and convenience, when combined with nerve biomaterials, provide broader application prospects for PNI repair, and has therefore become a research hot spot. This paper will review the combined application of physical stimulation and biomaterials in PNI repair in recent years to provide new therapeutic ideas for the future use of physical stimulation in PNI repair.
Moiré-driven electromagnetic responses and magic-angle in sandwiched hyperbolic metasurface

Recent moiré configurations provide a new platform for tunable and sensitive photonic responses, as their enhanced light – matter interactions originate from the relative displacement or rotation angle in a stacking bilayer or multilayer periodic array. However, previous findings are mostly focused on atomically thin condensed matter, with limitations on the fabrication of multilayer structures and the control of rotation angles. Structured microwave moiré configurations are still difficult to realize. Here, we design a novel moiré structure, which presents unprecedented capability in the manipulation of light – matter interactions. Based on the effective medium theory and S -parameter retrieval process, the rotation matrix is introduced into the dispersion relation to analyze the underlying physical mechanism, where the permittivity tensor transforms from a diagonal matrix to a fully populated one, whereas the permeability tensor evolves from a unit matrix to a diagonal one and finally becomes fully filled, so that the electromagnetic responses change drastically as a result of stacking and rotation. Besides, the experiment and simulation results reveal hybridization of eigenmodes, drastic manipulation of surface states, and magic angle properties by controlling the mutual rotation angles between two isolated layers. Here, not only a more precisely controllable bilayer hyperbolic metasurface is introduced to moiré physics, the findings also open up a new avenue to realize flat bands at arbitrary frequencies, which shows great potential in active engineering of surface waves and designing multifunctional plasmonic devices.
Comparison of Wuqinxi Qigong with Stretching on Single- and Dual-Task Gait, Motor Symptoms and Quality of Life in Parkinson’s Disease: A Preliminary Randomized Control Study

The objective of this study was to investigate the therapeutic effect of Wuqinxi Qigong vs. stretching on single- and dual-task gait, motor symptoms, and quality of life in people with mild and moderate Parkinson’s disease (PD). This single-blind, randomized control trial included 40 participants with idiopathic PD who were randomized into the Wuqinxi Qigong (WQ) group or stretching group. Participants completed 12 weeks (two sessions/week) of intervention. The primary outcomes were gait parameters when performing single-task (comfortable pace) and dual-task (obstacle crossing, serial-3 subtraction and backward digit span) walking, including gait speed, stride length, and double support percentage. The secondary outcomes were ratings from the Movement Disorder Society Unified Parkinson’s Disease Rating Scale (MDS-UPDRS), results of the timed-up-and-go test (TUGT), results of the Mini-Balance Evaluation Systems Test (MiniBESTest), and responses from the 39-item Parkinson’s Disease Questionnaire (PDQ-39). All measures were assessed pre- and post-intervention. The WQ group demonstrated increased gait speed (p = 0.000) during the single task, and increased stride length (p = 0.001, p = 0.021) during the single-task and serial-3 subtraction task. Double support percentage significantly decreased (p = 0.004) in the WQ group during the obstacle crossing task, and also decreased (p = 0.045) in the stretching group during the single-task. TUGT (p = 0.005), MiniBESTest (p = 0.023) and PDQ-39 (p = 0.043) in the WQ group significantly improved, and both groups showed significant improvement in MDS-UPDRS after intervention. Wuqinxi Qigong is an effective method to improve single- and dual-task gait. While both exercises improve motor symptoms, Wuqinxi Qigong results in better mobility, balance and quality of life compared to stretching alone.
ANXA10 Expression Is Inversely Associated with Tumor Stage, Grade, and TP53 Expression in Upper and Lower Urothelial Carcinoma

Introduction: Urothelial carcinoma (UC) is a common type of malignant disease, but little is known about the diagnostic and prognostic markers of upper urinary tract urothelial cancer (UTUC) because of its rarity. To clarify the significance of ANXA10 in UTUC, we studied ANXA10 expression with immunohistochemistry (IHC). Methods: The expression of ANXA10 was analyzed in the upper and lower urinary tract of UC by IHC in combination with The Cancer Genome Atlas (TCGA) data analysis. The association between ANXA10 expression and representative cancer-related molecules was also evaluated. Results: ANXA10 expression was weak in normal upper tract urothelium but was positive in 39/117 (33%) UTUCs. ANXA10 was more frequently positive in tumors with pure UC (36%, p < 0.05), papillary morphology (50%, p < 0.01), low grade (G1/2: 57%, p < 0.01), and pTa/is/1 stage (55%, p < 0.01) than in those with histological variants (0%), nodular morphology (9%), G3 (16%), and pT2/3/4 (13%), respectively. ANXA10-positive patients showed better cancer-specific survival and progression-free survival than ANXA10-negative patients (p < 0.05). IHC showed that ANXA10 positivity was detected more in cases with the low expression of TP53 (p < 0.01) and Ki-67 labeling index <20% (p < 0.01). In TCGA dataset of muscle-invasive bladder cancer, higher ANXA10 expression correlated with papillary morphology, lower grade/stage, luminal papillary subtype, wild-type TP53, and FGFR3 gene mutation. Conclusion: We revealed that ANXA10 expression was increased during carcinogenesis and was observed more frequently in papillary UC of lower grade and stage. However, its expression decreased as cancer progressed. Therefore, the ANXA10 expression in UTUC might be clinically useful for decision-making.
Forskolin Induces Endocrine Disturbance in Human JEG-3 Placental Cells

Forskolin, used in folk medicine since ancient times, is now available as a dietary supplement, with an indication as a fat burner and appetite suppressant. However, the safety of forskolin is poorly documented especially for pregnant women. The question that we raised is what about the safety of forskolin in pregnant women? As the placenta, an endocrine organ, is the key organ of pregnancy, we evaluated the in vitro placental toxicity of forskolin. We focused first on the activation of a P2X7 degenerative receptor as a key biomarker for placental toxicity, and second on steroid and peptide hormonal secretion. We observed that forskolin activated P2X7 receptors and disturbed estradiol, progesterone, hPL and hyperglycosylated hCG secretion in human placental JEG-Tox cells. To the best of our knowledge, we highlighted, for the first time, that forskolin induced endocrine disturbance in placental cells. Forskolin does not appear to be a safe product for pregnant women and restrictions should be taken.
Outcome-Driven Thresholds for Home Blood Pressure Measurement: International Database of HOme blood pressure in relation to Cardiovascular Outcome

The lack of outcome-driven operational thresholds limits the clinical application of home blood pressure (BP) measurement. Our objective was to determine an outcome-driven reference frame for home BP measurement. We measured home and clinic BP in 6470 participants (mean age, 59.3 years; 56.9% women; 22.4% on antihypertensive treatment) recruited in Ohasama, Japan (n=2520); Montevideo, Uruguay (n=399); Tsurugaya, Japan (n=811); Didima, Greece (n=665); and nationwide in Finland (n=2075). In multivariable-adjusted analyses of individual subject data, we determined home BP thresholds, which yielded 10-year cardiovascular risks similar to those associated with stages 1 (120/80 mm Hg) and 2 (130/85 mm Hg) prehypertension, and stages 1 (140/90 mm Hg) and 2 (160/100 mm Hg) hypertension on clinic measurement. During 8.3 years of follow-up (median), 716 cardiovascular end points, 294 cardiovascular deaths, 393 strokes, and 336 cardiac events occurred in the whole cohort; in untreated participants these numbers were 414, 158, 225, and 194, respectively. In the whole cohort, outcome-driven systolic/diastolic thresholds for the home BP corresponding with stages 1 and 2 prehypertension and stages 1 and 2 hypertension were 121.4/77.7, 127.4/79.9, 133.4/82.2, and 145.4/86.8 mm Hg; in 5018 untreated participants, these thresholds were 118.5/76.9, 125.2/79.7, 131.9/82.4, and 145.3/87.9 mm Hg, respectively. Rounded thresholds for stages 1 and 2 prehypertension and stages 1 and 2 hypertension amounted to 120/75, 125/80, 130/85, and 145/90 mm Hg, respectively. Population-based outcome-driven thresholds for home BP are slightly lower than those currently proposed in hypertension guidelines. Our current findings could inform guidelines and help clinicians in diagnosing and managing patients.
Atorvastatin Induced Constipation

A 72-year-old with high cholesterol levels (Hypercholesteremia) was advised to take Atorvastatin 20 mg (Atorva-20 mg) which led to constipation and abdominal discomfort. As management, the Atorvastatin was discontinued and replaced with Rosuvas-tatin. The symptoms of constipation were reduced after cessation of the suspect drug Atorvastatin. The possible mechanisms for the event were unknown but has some proposed mechanisms like1. Levels of Nitric oxide 2. Inhibiting the production of melvonic acid 3. Decrease in coenzyme Q10.
Research on the Design and Analysis Method of the Bird Collision-Resistant Structure of Electric Aircraft Composite Cap-Type-Reinforced Wall Panel-Filled Battery Integration

Compared with traditional energy aircraft, electric/hybrid aircraft show the advantages of environmental protection and low carbon and have been considered one of the most promising directions for the future development of the aviation industry. However, the battery (battery box) structure employed in electric/hybrid aircraft generally faces several problems (e.g., insufficient rigidity/strength and low structural load-bearing efficiency). In this study, the composite cap-type-reinforced wall plate structure commonly applied in electric aircraft is developed to fill the battery structure using the internal cavity of the cap type, which leads to the formation of an integrated structure type of a composite cap-type-reinforced wall plate filled battery. The basic static strength analysis of the integrated structure was conducted to measure its basic load-bearing capacity. To investigate the impact resistance of the integrated structure, a series of bird collision simulations were conducted to analyze the impact position, impact angle, impact speed, and other factors on the integrated structure and the design direction of the composite cap-type-reinforced wall plate-filled battery-integrated structure against bird collision was summarized.
Religious education projects with collaborative teaching and technology tools

Technology is the tool that can help theological colleges in many areas such as providing education platforms, making connection with the community and reaching existing students and even potential lay people. However technology cannot replace the strength of collaboration of people and community. In this paper, two projects of HKSKH Ming Hua Theological College Lai Wong Yan Lin Library (MH Library) will be highlighted. One project provides religious courses to people around the world; the other project is for local secondary schools students using the theme of “Life Education with positive thinking” to help their personal growth and digital literacy skills. These projects show how a theological library team acts as an academic link for a theological college to spread knowledge and creates inter-religious possibilities beyond the physical limitation of the College buildings. The MH library team uses collaborative teaching (religious and Life Education courses by teachers; digital literacy skills by librarians), and develops IT tools (especially the MH Global Classroom System and online IT tools) as learning and communication platforms for teachers, students, public and outside organizations with different religious and non-religious backgrounds.
Challenges And Solution of Artificial Intelligence in Cyber Security

A computer can completely perform like a person thanks to the advancement of information technology. A machine that responds and performs like a human brain is required for AI, an amazing feature of information technology. Touch and speech are recognized by the system as qualities that can be used to operate potential daily operations without human intervention. Artificial intelligence, on the other hand, is the study of an intelligence "agent" that effectively completes a task while taking the state of the environment into account. The majority of computing systems are created to fulfil certain functions based on the context, applying special traits drawn from components of human nature that exist inherently. Using approaches and understanding of higher-level human-inspired elements, judgement, and emotions flow working, artificial intelligence frequently collaborates with mankind to fix the problem. Artificial intelligence is intelligence based on machines as opposed to human intelligence. A single person cannot manage the complexity of activities and the volume of information needed to secure cyberspace without significant automation. But in order to adequately defend against security risks, technology and software with conventional fixed implementations are challenging to design. AI machine learning and simplification techniques can be used to treat this issue. After reviewing the available artificial intelligence software for cyber security, we may assume that useful applications currently exist. They employ neural networks to first secure the perimeter and many other cyber security domains. On the other hand, it was evident that certain cyber security issues could only be effectively solved by the application of artificial intelligence techniques. This study paper's objective is to assess the existing difficulties posed by artificial intelligence for cyber security. The research report will include ground-breaking suggestions for AI in cyber security.
