Lombalgia e o equilíbrio corporal de atletas da seleção Brasileira feminina de canoagem velocidade

Low back pain has been shown to interfere with body stability. In sports, the study of these relationships is important because the bouts may influence the results of training and competitions. High rates of injury to the lumbar region have been reported for elite female canoe paddlers. The objective of this study was to assess the influence of low back pain on body balance in female athletes of the Brazilian flatwater canoe team. Athletes with low back pain (in the last week) were compared to those without pain in the two-leg and single-leg stance, with the eyes open and closed, using an AccuSway Plus force platform (Advanced Mechanical Technology, Inc.). The variables analyzed were the amplitude of the pressure center in the anteroposterior direction (COPap) and medial-lateral direction (COPml). The results showed higher body ins- tability for athletes with low back pain. For COPml, no significant difference between the two groups was observed for only one condition (single-leg stance) (p = 0.901), and for COPap, no significant difference was observed for two conditions (p = 0.414 and p = 0.567), i.e., single-leg stance and eyes closed. In conclusion, low back pain was harmful to body balance in high-level female canoe paddlers.
Learning based versus heuristic based: A comparative analysis of visual saliency prediction in immersive virtual reality

While visual saliency has been used for various purposes in virtual reality (VR), the efforts to properly understand the saliency mechanism in VR remain insufficient. In this paper, we present an extensive comparative analysis of learning‐based and heuristic‐based approaches to visual saliency prediction in immersive VR experienced using head‐mounted‐displays with a particular focus on the contribution of the depth cue. To this end, we use three learning‐based RGB‐D image saliency detection methods and two heuristic‐based RGB‐D image saliency detection methods on a VR dataset curated from three distinct virtual environments under two‐dimensional and three‐dimensional viewing conditions. Additionally, we extend the analysis by including a heuristic‐based RGB video saliency detection method and its depth‐infused version. The results acquired using these seven methods reveal the superiority of the learning‐based RGB‐D image saliency prediction methods in VR and validate the importance of the depth cue in the saliency prediction of virtual environments.

Virtual Reality for Shoulder Rehabilitation: Accuracy Evaluation of Oculus Quest 2

Virtual reality (VR) systems are becoming increasingly attractive as joint kinematics monitoring systems during rehabilitation. This study aimed to evaluate the accuracy of the Oculus Quest 2 in measuring translational and rotational displacements. As the Oculus Quest 2 was chosen for future applications in shoulder rehabilitation, the translation range (minimum: ~200 mm, maximum: ~700 mm) corresponded to the forearm length of the 5th percentile female and the upper limb length of the 95th percentile male. The controller was moved on two structures designed to allow different translational displacements and rotations in the range 0–180°, to cover the range of motion of the upper limb. The controller measures were compared with those of a Qualisys optical capture system. The results showed a mean absolute error of 13.52 ± 6.57 mm at a distance of 500 mm from the head-mounted display along the x-direction. The maximum mean absolute error for rotational displacements was found to be 1.11 ± 0.37° for a rotation of 40° around the z-axis. Oculus Quest 2 is a promising VR tool for monitoring shoulder kinematics during rehabilitation. The inside-out movement tracking makes Oculus Quest 2 a viable alternative to traditional motion analysis systems.
Effectiveness of reactive hepatitis therapy in injured with ballistic wounds

Reactive hepatitis complicates the treatment of ballistic wounds. The aim of our study was to study the clinical and pharmacoeconomic effectiveness of the treatment of reactive hepatitis in the wounded. A prospective study of 112 wounded servicemen with increased transaminase activity was randomized into three groups: group I received arginine glutamate intravenously for 10 days, group II received phosphatidylcholine intravenously for 10 days, and group III received standard treatment. In the presence of hypoalbuminemia, the wounded received intravenous infusions of albumin to normalize its level in serum. The initial level of alanine aminotransferases was 62.5 in group I patients [50.5; 80.0] IU / l, in the second group - 64.0 [48.5; 83.0] IU / l and 62.0 [47.0; 85.5] IU / l, respectively, in group III (p> 0.05 according to the Mann-Whitney test). In the period up to 14 days after injury, alanine aminotransferase levels decreased significantly in all groups (p <0.05 according to Wilcoxon's test) and amounted to 38.5 in group I [34,0; 63.5] IU / l, in the second group 46.0 [32.0; 62.5] IU / l, in group III 50.0 [40.0; 78.0] IU / l (p = 0.014 according to the Mann-Whitney test compared to group I). In 14 and more days after injury in all groups the average concentration of alanine aminotransferases was significantly lower compared to the previous study period (p <0.05 according to Wilcoxon’s test): in group I the concentration of alanine aminotransferases was 33.0 [29,8; 40.0] IU / l (p = 0.048, p <0.001 according to the Mann-Whitney test in comparison with group II and III, respectively), in group II - up to 38.0 [31.0; 62.0] and in group III to 48.0 [39.5; 69.0] (p = 0.014 according to the Mann-Whitney test compared to group II). Also, there was a tendency to reduce the frequency of complications from internal organs: in 13% (8 of 63) patients of groups I and II, compared with 27% (13 of 49) of group III (p = 0.063). Significantly decreased both the duration of treatment in the intensive care unit: in group I (4.2 ± 1.8) days, compared with group III (7.4 ± 6.0) days, p = 0.012, and the duration of total hospital stay (20.4 ± 11.1) days for group I, compared with (29.7 ± 3.5) days for group III, p = 0.022. In the cost-effectiveness analysis of arginine glutamate and phosphatidylcholine regimens, a 2-fold better cost-effectiveness ratio was found in the group of reactive hepatitis wounded who received arginine glutamate.

Supporting Behavior Change After AECOPD – Development of a Hospital-Initiated Intervention Using the Behavior Change Wheel

Abstract After hospitalization due to acute COPD exacerbations, patient-manageable behaviors influence rehospitalization frequency. This study’s aim was to develop a hospital-ward-initiated Behaviour-Change-Wheel (BCW)-based intervention targeting patients’ key health behaviors, with the aim to increase quality of life and reduce rehospitalization frequency. Intervention development was performed by University Hospital Zurich working groups and followed the three BCW stages for each of the three key literature-identified problems: insufficient exacerbation management, lack of physical activity and ongoing smoking. In stage one, by analyzing published evidence – including but not limited to patients’ perspective – and health professionals’ perspectives regarding these problems, we identified six target behaviors. In stage two, we identified six corresponding intervention functions. As our policy category, we chose developing guidelines and service provision. For stage three, we defined eighteen basic intervention packages using 46 Behaviour Change Techniques in our basic intervention. The delivery modes will be face-to-face and telephone contact. In the inpatient setting, this behavioral intervention will be delivered by a multi-professional team. For at least 3 months following discharge, an advanced nursing practice team will continue and coordinate the necessary care package via telephone. The intervention is embedded in a broader self-management intervention complemented by integrated care components. The BCW is a promising foundation upon which to develop our COPD intervention. In future, the interaction between the therapeutic care team-patient relationships and the delivery of the behavioral intervention will also be evaluated.
Interleukin-5 Levels in Chronic Rhinosinusitis Patients With and Without Allergy

Introduction: Chronic rhinosinusitis (CRS) is an inflammation of the nasal mucosa and paranasal sinuses that is present for more than 12 weeks. The pathogenesis of allergic CRS includes mucosal edema and causes sinus ostial obstruction, which. It leads to the infection of the paranasal sinuses. Interleukin- 5 (IL-5) is a cytokine and acts in eosinophil and basophil biology. It is the main effector unit of allergic reactions. Aim: This study aimed to determine IL-5 levels in allergic and nonallergic chronic rhinosinusitis patients. Material and methods: A comparative analytic cross-sectional study was used. A total of 10 allergic chronic and 10 nonallergic chronic rhinosinusitis patients took part in this study. The real-time polymerase chain reaction (RT-PCR) method was used to determine gene expression. Data were analyzed with SPSS. A p-value below 0.05 was considered statistically significant. Results: IL-5 gene expression in non-allergic chronic rhinosinusitis was higher than in allergic chronic rhinosinusitis. IL-5 gene expression was not significant between chronic non-allergic and allergic chronic rhinosinusitis (p > 0.05). There was an elevated IL-5 gene expression in non-allergic chronic rhinosinusitis, but it was not significant compared to chronic allergic rhinosinusitis.
Fault-Tolerant Control for Path-Following of Independently Actuated Autonomous Vehicles Using Tube-Based Model Predictive Control

This paper designs a fault-tolerant controller for the path-following of independently actuated (IA) electric autonomous vehicles (AVs) with steer-by-wire (SBW) systems. Such a controller can handle the effect of steering motor fault and the bounded disturbances of the vehicle dynamic system. Firstly, we formulate the dynamic models of the vehicle, the tire, the SBW system, and the steering motor. Secondly, with the models, we identify the effectiveness coefficient of the steering motor and calculate the steering resistance torque. Both the two parameters are used to determine the potential maximum front-wheel angle. The effectiveness coefficient can determine when the control system switches to the fault-tolerant control (FTC) mode. For the FTC mode, we then introduce a tube-based model predictive control (MPC) framework to guarantee vehicle stability in steering processes and maintain the tracking performance. The disturbances of the vehicle dynamic system affect both the control input and the state. On one hand, the disturbances are formulated to be a tightened state constraint. On the other hand, together with the potential maximum front-wheel angle, the disturbances are formulated to be a tightened input constraint. Finally, we show the effectiveness of the designed fault-tolerant controller via Carsim-Simulink joint simulation and real-vehicle experiment.
Reliability-Based Large-Vocabulary Audio-Visual Speech Recognition

Audio-visual speech recognition (AVSR) can significantly improve performance over audio-only recognition for small or medium vocabularies. However, current AVSR, whether hybrid or end-to-end (E2E), still does not appear to make optimal use of this secondary information stream as the performance is still clearly diminished in noisy conditions for large-vocabulary systems. We, therefore, propose a new fusion architecture—the decision fusion net (DFN). A broad range of time-variant reliability measures are used as an auxiliary input to improve performance. The DFN is used in both hybrid and E2E models. Our experiments on two large-vocabulary datasets, the Lip Reading Sentences 2 and 3 (LRS2 and LRS3) corpora, show highly significant improvements in performance over previous AVSR systems for large-vocabulary datasets. The hybrid model with the proposed DFN integration component even outperforms oracle dynamic stream-weighting, which is considered to be the theoretical upper bound for conventional dynamic stream-weighting approaches. Compared to the hybrid audio-only model, the proposed DFN achieves a relative word-error-rate reduction of 51% on average, while the E2E-DFN model, with its more competitive audio-only baseline system, achieves a relative word error rate reduction of 43%, both showing the efficacy of our proposed fusion architecture.
RoSense: Refining LOS Signal Phase for Robust RFID Sensing via Spinning Antenna

RFID sensing leveraging backscatter signal features (e.g., phase shift) from tags has gained increasing popularity in numerous applications but also suffers from negative impacts of environmental multipaths. Past works to address it rely on extra customized devices, labor-intensive offline training, or frequency channel hopping, all of which are non-ubiquitous or ineffective for real-life adoption. This article presents RoSense, a universal method to alleviate multipath reflections’ impacts by spinning the reader antenna, thus enabling more robust RFID sensing. Besides, RoSense requires no RF devices or offline training and operates in a nonintrusive manner. The key insight of RoSense is to exploit two properties of line-of-sight (LOS) signal when spinning the antenna, i.e., the linearity of phase changes and stability of received signal strength to attenuate the nonlinear and nonmonotonic effect of multipath signals and refine the phase shift of LOS signal. We have implemented a prototype of RoSense with COTS devices and studied two cases for evaluation: 1) material identification and 2) object localization. Experimental results show that RoSense can improve the material identification accuracy by up to 16.22% and reduce the mean localization error by up to 39.93%, greatly outperforming the state-of-the-art solutions.
The Divorce of Ownership from Control and Stakeholders

It is said that within a company, shareholders are after profit making while managers are after their own interests. Also, corporations are said to have stakeholders other than shareholders and managers that are affected by the actions they take, though not owning or employed by them. It will be discussed in this essay that whether the statement is accurate.
Multi-Echelon Inventory Management for a Non-Stationary Capacitated Distribution Network

We present an inventory management solution for a non-stationary capacitated multi-echelon distribution network involving thousands of products. Assuming backlogged sales, we revisit and leverage the seminal multi-echelon inventory management results in the literature to establish the structural properties of the problem, and derive an eﬃcient and practical solution method. In particular, we describe how the additive separability nature of the objective function can be used in a dynamic programming framework to circumvent the usual curse of dimensionality inherent to high-dimensional inventory management problems. We incorporate features such as asynchronous replenishment intervals at the diﬀerent echelons, accounting of perishability, capacity constraints (both volume and ﬂow), stochastic lead times, reverse logistics, supply risk and risk-pooling. Illustrative examples demonstrate some of these features. A version of this model was tested at a large grocery retailer in a two-layer network, resulting in a statistically signiﬁcant increase of availability, sold units, and revenue, while lowering inventory volume at the hub.
Evidence of Metallic and Polyether Ionophores as Potent Therapeutic Drug Candidate in Cancer Management

Cancer remains one of the most crucial human malignancies with a higher mortality rate globally, and is predicted to escalate soon. Dysregulated ion homeostasis in cancerous cells prompted the researchers to investigate further ion homeostasis impeding agents as potent anticancerous agents. Reutilization of FDA-approved non-cancerous drugs has emerged as a practical approach to developing potent, cost-effective drugs for cancer treatment. Across the globe, most nations are incapable of fulfilling the medical demands of cancer patients due to costlier cancerous drugs. Therefore, we have inclined our review towards emphasizing recent advancements in cancer therapies involving ionophores utilization in exploring potent anticancer drugs. Numerous research reports have established the significant anticancerous potential of ionophores in several pre-clinical reports via modulating aberrant cell signaling pathways and enhancing antitumor immunity in immune cells. This review has mainly summarized the most significant ion homeostasis impeding agents, including copper, zinc, calcium, and polyether, that presented remarkable potential in cancer therapeutics via enhanced antitumor immunity and apoptosis induction. Altogether, this study could provide a robust future perspective for developing cost-effective anticancerous drugs rapidly and cost-effectively, thereby combating the limitations of currently available drugs used in cancer treatment.
“Intervention Program Based on Self”: A Proposal for Improving the Addiction Prevention Program “Unplugged” through Self-Concept

The “Intervention Program based on Self” (IPSELF) project was created to address the gap between the acquisition of life skills during prevention programs and their application with a session for developing one’s self-concept included in the European program “Unplugged”. The present study evaluated its effectiveness. A total of 157 middle school students (94 girls, 63 boys, MAGE = 12.89, SD = 0.45) from three schools in France participated in this study. The participants attended one of two programs (Unplugged/IPSELF). The effectiveness of the IPSELF add-on session was measured with the Self-Concept Clarity Scale, and the differences between the two programs was measured with the prototype willingness model. Adolescents in IPSELF rated the typical nonsmoker and cannabis nonsmoker more favorably, and the typical drinker less favorably. They felt more different from the typical smoker and drinker after participation in IPSELF. More alcohol experimenters were observed in Unplugged. The knowledge gained in IPSELF appeared to help adolescents more than that gained in Unplugged to change their smoking behavior. Furthermore, IPSELF had a more beneficial effect for girls, who felt that they had gained more control over their alcohol and cannabis use than boys, whereas Unplugged had a more positive effect on boys, who gained better control over their consumption. Moreover, the girls felt that they had gained more knowledge about the substances discussed in IPSELF than in Unplugged. We therefore recommend the use of IPSELF especially with female audiences.
The Power of Teaching Strategy and its Impact on Children with ADHD

Attention deficit hyperactivity disorder (ADHD) is a type of disorder caused by brain dysfunction that is easy to be found in childhood, and it is common in children, adolescents, and adults. Although there is a lot of research on attention deficit hyperactivity disorder (ADHD), there seems to be a lack of comprehensive research on educational strategies and their effects on this disorder. This literature review attempts to discuss what ADHD is and some risk factors associated with the prevalence of ADHD, the executive function problems associated with ADHD and related interventions, other possible interventions or educational strategies, and ultimately, what kind of collaboration relationship should be achieved between the educator and the parent or family will be discussed.
MODECP: A Multi-Objective Based Approach for Solving Distributed Controller Placement Problem in Software Defined Network

Software-Defined Network is an emerging networking paradigm that enables intelligent and flexible network management. Specifically, the design of the control plane is crucial. Therefore, in order to avoid a single point of failure, multiple controllers are deployed constantly in a distributed manner on the control plane. In this paper, we propose a controller placement approach based on multiple objectives (MODECP), including network delay, network security, load-balancing rate, and link occupancy. In the controller placement stage, an improved multi-objective differential evolution algorithm is proposed to search for controllers’ positions and assign switches to controllers reasonably. Furthermore, an improved affinity propagation algorithm is proposed to obtain the number of controllers placed in the network partition stage, comprehensively considering the delay, node security, and load. Simulations are performed based on several topologies from Internet Topology Zoo. Extensive results show that the proposed algorithm can realize trade-offs among multiple objectives and improve network performance in delay, security, controller load, and link occupancy compared to the single-objective based approach. Moreover, compared with the genetic algorithm and random placement algorithm, the proposed algorithm performs better with low latency, high security, low load rate, and low link overhead.
