EFFECTS OF VIRTUAL REALITY-BASED TREADMILL TRAINING ON BALANCE AND GAIT IN STROKE PATIENTS: A RANDOMIZED CONTROLLED TRIAL

: Gait and balance impairments contribute significantly to long-term disability after stroke. Modern concepts of stroke rehabilitation recommend a task-specific repetitive approach, such as using treadmill training. The purpose of this study was to investigate the effectiveness of using virtual reality-based treadmill training to improve balance and gait in subacute stroke patients. Twenty-two stroke patients were randomly stratified into two groups: the experimental (n = 11) and the control group (n = 11). Parameters associated with balance and gait were measured using the 6-minute walk test, the 10-meter walk test, the timed “up and go” test, the functional gait assessment, and the four square step test. Gait analysis using the zebris Rehawalk® treadmill system was also performed. Patients in the experimental group received virtual reality-based treadmill training five times a week for a period of four weeks, while those in the control group received treadmill training at the same frequency, duration, intensity, and structure, along with a progressively more difficult task demands. Significant improvements were observed in selected outcome measures in both groups after training. Patients in the experimental group experienced improvements in all of the spatiotemporal gait parameters, but there was a significant difference before and after training in duration of double support and lateral asymmetry. The findings of this pilot randomized controlled trial support the benefits of using a virtual reality-based treadmill training program to improve gait and balance in subacute stroke patients.
Volatile organic compound profi ling of Capsicum annuum var . longum grown under diff erent concentrations of nitrogen

Summary Emission of volatile organic compounds (VOCs) in plants is triggered by several biotic and abiotic factors, such as nutrient defi ciency, environmental stress, and pathogenic attacks. For instance, plants suff ering from limited or excessive nitrogen (N) supply may experience internal stress which can ultimately lower their stability and immunity making them susceptible to infection and infestation. In this study, VOCs from Capsicum annuum var. longum (Solanaceae) exposed to nitrogen (1.8 g/L, 4.5 g/L, and 9 g/L urea) were extracted using a 100 μm Solid Phase Microextraction (SPME) fi ber coated with polydimethylsiloxane (PDMS). Using Gas Chromatography-Mass Spectrometry (GC-MS), extracted VOCs from N-treated plants were identifi ed as Butanoic acid, 3-hexenyl ester, (E)-; Butanoic acid, hexyl ester; Hexanoic acid, 3-hexenyl ester, (Z)-; Hexanoic acid, 4-hexen-1-yl ester; cis-3-Hexenyl cis-3-hex-enoate and 4-Pentenoic acid 2-methyl-, hexyl ester. Among these volatiles, butanoic acid, 3-hexenyl ester showed the most distinctive peak from the N-treated plants in comparison with the untreated. In addition, the Green Leaf Volatiles (GLV) 3-Hexenal; 2-Hexenal; 3-Hexen-1-ol, (Z)-; 2-Hexen-1-ol, (E) and 1-Hexanol were also detected from the N-treated plants. The identifi cation of plant volatiles provides useful information that can be used in agricultural practices and plant phenotyping.
MASSIVE GOITRE (STRUMA PARENCHYMATOSA) IN GEESE

In a goose flock consisting of 2300 birds of 6 months of age severe goitre was diagnosed. To the best of our knowledge this is the first report of naturally occurring goitre in geese, which is not related to the feeding of rapeseed meal. The major pathological findings included retarded growth and plumage development, significantly (300%) increased relative thyroid weight, fat accumulation in the mesenteric and abdominal region, and lipid infiltration of liver and kidney cells. Subsequent hormone analysis showed undetectable thyroxine (T 4 ) levels and a dramatic drop in triiodothyronine (T 3 ) plasma levels of the diseased geese. Thyroidal histology displayed the typical signs of struma parenchymatosa. In order to get more information about the possible causes of the goitre, 10 geese from the affected farm were transferred into the laboratories of the Central Veterinary Institute. The geese were allotted into two groups. Group I received iodine supplementation for 55 days, while the other group served as sick control (Group S). Iodine treatment caused a dramatic improvement in the birds(cid:146) clinical condition except in plumage growth in Group I, while the clinical and main pathological signs of goitre remained unchanged or worsened in the untreated Group S. Contrary to this, the serum levels of thyroid hormones and responsiveness to thyrotropin releasing hormone (TRH) improved not only in Group I but also in Group S. Almost euthyroid biochemical parameters were found after 55 days of iodine treatment in Group I and, surprisingly, a considerable improvement (especially in serum T 3 levels) occurred also in Group S. These findings confirm the diagnosis of goitre but also call attention to the fact that iodine deficiency was not the only factor eliciting the disorder. The underlying possible goitrogenic substance could not be traced down.
A Comparative Study of 25-Hydroxyvitamin D Level and Associated Parameters in chronic kidney disease (CKD) and Dialysis Patients in Shiraz, Iran

Background: Vitamin D deficiency and insufficiency are generally observed in chronic kidney disease (CKD) and dialysis patients. The goal of this work was to compare the serum levels of vitamin D and its-related metabolic parameters in CKD patients and hemodialysis patients. Materials and Methods: A total of 109 dialysis patients and 99 CKD patients who had not consumed vitamin D for ≥ 1 year were enrolled in this study. 25-Hydroxy vitamin D (25-(OH) D) levels, calcium, alkaline phosphatase (ALP), hemoglobin (Hb), hematocrit (HCT), total iron-binding capacity (TIBC), parathyroid hormone (PTH), and phosphorous were evaluated in the serum of the patients. Results : 25-(OH) D levels in patients with CKD and dialysis patients were 31.73±13.34 ng/mL and 15.52±5.36 ng/mL, respectively. The levels of calcium (P=0.000), ALP (P=0.006), 25(OH) D (P=0.000), FBS (P=0.000), Hb (P=0.002), HCT (P=0.002), and TIBC (P=0.000) were significantly higher, and the levels of PTH (p=0.000) and phosphorous (P=0.000) were significantly lower in the CKD group compared to dialysis group. Conclusion: The 25-(OH) Vitamin D levels and its metabolic parameters except PTH and phosphorus are lower in patients on dialysis compared with the patients with CKD.
Redescription of Rhinus ciliatus (Gastropoda: Simpulopsidae), An Endemic Species from the Atlantic Rainforest in Brazil

ABSTRACT The genus Rhinus Martens, 1860, is represented in Brazil by about twenty species, which are predominantly found in the Atlantic rainforest, an endangered ecosystem with extraordinary biodiversity and high endemism. There is a dearth of detailed morphological data for most species of the genus Rhinus, and the anatomy of only a few species has been described. Rhinus ciliatus, an endemic species from southwestern Brazil, is known by few conchological traits and scarce anatomical data from the reproductive system and pallial cavity. In this study, we redescribe the shell morphology and soft body anatomy of Rhinus ciliatus in detail and compare the new data with known traits of other closely related species. Rhinus ciliatus is diagnosed by the following features: (i) transition from protoconch to teleoconch well marked; (ii) shell ovate-conic, accuminate; (iii) aperture sub-ovate, lip simple; (iv) kidney with granulated lamellae; and (v) marginal teeth with blunt spatula-shaped mesocones. The record of spermatophores for the genus is provided here for the first time.
Reproduction and Recruitment of the Intertidal Clam Darina solenoides (Bivalvia: Mactridae) in Patagonian Sandy Shores, Argentina

ABSTRACT Darina solenoides (P. P. King, 1832) is an abundant clam of sandy shores of southern South America. It has an essential ecologic role as a main food source for marine predators, including migratory seabirds, and is an intermediate host in parasitic life cycles. We describe the reproductive cycle and recruitment of D. solenoides in relation to environmental factors in central Patagonia, Argentina. Histological analysis of gonadal stages and quantitative indicators such as the condition index (CI), oocyte density and relative oocyte area (ROA) were examined monthly for two years (2016–2017; n = 1,315) from clams collected from two sandy shores of the San Jorge Gulf (SJG). Recruitment pattern was followed at a single site. The shell lengths ranged between 25.2 and 42.8 mm and the sex ratio did not differ significantly from 1:1. The proportion of clams showing total or partial castration by digenean trematodes was low (< 5%). A clear annual reproductive cycle was found and was characterized by high synchrony between sexes, years and sites. Proliferation of gonia extended throughout the colder months and vitellogenesis occurred mainly during the spring increase of seawater temperature and shortly after the major phytoplankton bloom. Maximum development of oocytes (mean diameter, 32.1 ± 12.9 µm) and presumed spawning by both males and females occurred during the austral summer. Settlement was also highest (mean = 162.8 ± 47.1 ind.m-2) during summer and was coincident with a second phytoplankton bloom that might favour larval development and subsequent early recruitment. This is the first reproductive study of a mactrid bivalve from the southwest Atlantic Ocean and provides useful information on the population dynamics of this key species from Patagonian sandy shores.
Blending CNNs with different signal lengths for real-time EEG classification sensitive to the changes

Although a lot of BMI research using CNN has been performed, CNN’s response to changes in the input EEG is too late to proceed in real-time. We propose a method to improve the real-time performance by blending multiple CNNs with different input signal length. The proposed method generates a classifier which has the advantage of a classifier with short input signal length, i.e., fast response to changes in the input signal, and also the advantage of a classifier with long input signal length, i.e., high classification performance.
Water and Sanitation as a Wicked Governance Problem in Brazil: An Institutional Approach

The world is facing a large number of interrelated crises that have seriously increased the level of uncertainty and ambiguity in many areas. In 2018, the UN anticipated that the world was careering toward a global water crisis with a 40% shortfall in freshwater resources by 2030 coupled with a rising population. This nascent crisis represents a “connected challenge” for countries: it contains a multitude of causes and consequences, a multitude of actors and interests for which no “one-size-fits-all” solutions are available. The adequate approach to this type of complex—or “wicked”—problems is not to search for technological solutions only, but to consider new forms of governance that make use of complementary institutional logics. Effective governance depends on the extent of alignment with the complexity and the root causes of the issues. This paper applies wicked problem theory to identify the root institutional and governance causes of uncertainty in a developing country like Brazil, which provides insights to (also) identify approaches that could navigate change in less uncertain and ambiguous directions. We distinguish three types of relevant institutional constraints: logics, complementarities, and voids. Based on semi-structured interviews with representatives from Brazil's water and sanitation sector, we delineate institutional constraints precipitated by the plurality of the governance system. We argue why a tripartite partnership approach—as for instance pioneered by Dutch international water projects in the global South—presents a way out of the wicked water and sanitation problems in Brazil.
Achieving fast page load for websites across multiple domains

The dependencies between the resources on web page slow down the page load process, resulting in degradation of user experience and provider revenue. Recent solutions reprioritize requests at client side to fetch resources according to the page's dependency structure. However, since resources on modern web pages are often served by the direct‐connect and multiple third‐party domains, optimizing web performance only at the client side is not able to minimize the long waiting time for the resources across multiple domains. To address this inefficiency problem, we present fast page load (FPL), a scheme of restructuring the interaction between multiple domains to accelerate web page loads. The key of our solution is that the credible servers in third‐party domains proactively push resources to client with the aid of server in the direct‐connect domain. Therefore, FPL eliminates the waiting time of resource requesting and TCP handshaking between the client and servers in third‐party domains. Furthermore, we propose FPL+ to schedule resources based on the dependency and size of objects to improve user perception and experience in terms of time‐to‐first‐paint. Experiment results show that our approach FPL and FPL+ effectively reduces the median page load time by up to 44% across popular websites.
Low-q dispersion of transverse acoustic phonons in YBa_ 2 Cu_ 3 O_ 7 (cid:0)

High-resolution (∆ E =1.3 meV) inelastic X-ray scattering (IXS) in optimally doped untwinned YBa 2 Cu 3 O 7 − δ single crystals show that the dispersion of transverse acoustic phonons in the a direction remains linear with no softening due to bending modes in the long wavelength limit, down to q =0.02. The sound velocity is found to be 2700 ± 70 m s − 1 , in excellent agreement with ultrasound measurements, and unchanged upon cooling from room temperature to 98 K. These results rule out a strong coupling between bending dynamics of the CuO 2 planes and charge carriers in cuprates. hitherto unexplored low- q region. Using IXS with a very high resolution in energy, ∆ E =1.3 meV, we measured the dispersion relation from q =0.3 down to q =0.02 in YBa 2 Cu 3 O 7 − δ single crystals. In the q ≤ 0 . 1 region, the data show no deviation from linearity either at room temperature or at 98 K, the latter temperature being well inside the region of superconducting ﬂuctuations. These results rule out a strong coupling between bending dynamics of the CuO 2 layers and high- T c superconductivity in cuprates, and furthermore demonstrate the feasibility of accurate measurements of very low- q modes by means of

A Conceptual Framework for Understanding Armed Non State Actors (ANSAs): Strategic Roles and Operational Dynamics

Abstract : This is the Final Report of the Technology Investment Fund (TIF) Project entitled A Conceptual Framework for Understanding Armed Non-state Actors (ANSAs): Strategic Roles and Operational Dynamics (Project Code: 10az01). The Socio-cognitive Systems Section (SCSS) at Defence Research and Development Canada (DRDC), Toronto Research Centre, undertook this multi-year Project in order to advance our understanding of the motivation, intent, and behaviour of ANSAs. Consistent with DRDCs support-to-operations mandate, this understanding will help the Canadian Armed Forces (CAF) effectively engage these actors in future expeditionary operations. The in-house Project team and two world-class academic contracting teams carried the Project through three Phases. Phase 1 Conceptual Development established the boundaries of the conceptual problem space. Phase 2 Framework Calibration calibrated the first-cut Irregular Adversary (Insurgent) [IA(I)] Concept Map (Cmap)8 using a real-world test case the Somali Islamist ANSA al-Shabaab. Phase 3 Project Integration integrated the findings of the first two phases and recast the IA(I) Cmap in order to create the key end-product of this Project: the ANSA Cmap. The generic ANSA Cmap is a high-level conceptual framework grounded in both multidisciplinary theory and mixed methods practice that distills our understanding of these actors to its core strategic-level factors. It serves as a cognitive model or primer on this class of irregular adversary as well as a knowledge model or template for organizing and managing the overwhelming mass of information collected on ANSAs. The Projects independent research thrusts triangulated on two critical factors that featured as focal elements of the ANSA Cmap, that is, the competition between the in group and an out group(s) (social conflict), and the perceived threat to the future vitality of the in group arising from this competition (collective threat).
Technical and Economical Comparison between

This paper presents a technical and economical comparative analysis between two topology of photovoitaic plant. In particular the performances of series­parallel (SP) and total cross tied (TCT), topologies are taken into account, referring to a partially shaded photovoitaic plant. Thanks to a simulation model developed, in the paper the mismatch effects due to three different shading conditions, for SP and TCT topology plant, are quantified. Since the TCT solution, even though increase the energy production, raise the complexity of plants as well as their costs, an evaluation of the individual costs of each component of a SP and TCT plant topology, as PV modules, support structure, inverter, protection devices, cables and wiring, ordinary maintenance and so on, is carried out.

Activation State-specific Monoclonal Antibody Detects Tyrosine Phosphorylated pl85â€ž*Â«/*r*B-2Â¡na Subset of Human Breast Tumors Overexpressing This Receptor1

Amplification of the neu/erbB-2/HER-2 gene and/or overexpression of its receptor tyrosine kinase product, piss"""'"*8"2 (pl85), occurs in 15-40% of primary human breast tumors and is variably correlated with poor patient prognosis. Variability in predictive accuracy likely results from activation of pl85 by agonist(s) in only a subset of tumors in which it is overexpressed, which may greatly affect outcomes. As a first step toward evaluating this hypothesis, we previously produced a polyclonal antibody that specifically recognizes the activated, tyrosine-phosphory-lated forms of p185 and the closely related epidermal growth factor receptor (L. Bangalore et al., Proc. Nati. Acad. Sci. USA, 89: 11637-11641, 1992). We now describe the production of a inAh, PN2A, that specifically recognizes tyrosine-phosphorylated pl85 and bears no cross-reactivity with closely related receptors. Furthermore, we demonstrate its reactivity in immunohistochemical staining of paraffin-embedded, formalin-fixed tumor samples. In a series of five pl85-overexpressing human tumors examined thus far, PN2A reactivity was detected in two, indicating that pl85 is phosphorylated and hence actively signaling in a subset. This reagent will facilitate both clinical and research analyses of pl85 activity. Furthermore, this work serves as a prototype for similar analyses of other tyrosine phosphoproteins.
Critical Challenges and Solutions for an Ultra-Large-Scale Enterprise DevOps Platform

As the enterprise IT systems continuously migrate to cloud, conventional waterfall development process model undermines system flexibility and brings some unacceptable disadvantages, such as slow delivery of business requirements, long release cycles and high risk of manual deployment. However, adopting the DevOps methodology can solve these problems as it helps enterprise develop and deliver IT systems and software products efficiently. Based on the widely adopted processes and toolchains, we have developed a novel ultra-large-scale enterprise application development platform, YunDao. Although it has achieved many successes and wide applications, some critical challenges still exist with the promotion and extensive use of this advanced platform. In this study, a preliminary analysis was conducted on the critical challenges during the operation and maintenance process. Some solutions were proposed and discussed to grapple with these issues to further optimize the platform. This work can contribute to the understanding the DevOps concept, yielding new insights into developing and optimizing other ultra-large-scale platforms.
Intrusion Detection System Based on Machine Learning Algorithms: A Review

Due to the widespread use of the internet, computer networks are vulnerable to cyber-attacks, prompting various researchers to suggest intrusion detection systems (IDSs). Detecting intrusions is one of the important research topics in network security. As a precaution to guarantee the network's security, it aids in the detection of unwanted usage and assaults. This study summarizes significant literature reviews on machine learning (ML), and deep learning (DL) approaches for intrusion detection network analysis and includes a brief instructional overview of each ML / DL method. The papers describing each approach were indexed and summarized according to the dataset used, and the highest level of accuracy was attained.
Design of Self Biased Rail to Rail Input Operational Amplifier

Operational amplifiers use a large number of external bias voltages. These results in numerous drawbacks, namely, an area and power overhead, susceptibility of the bias lines to noise and cross-talk and high sensitivity of the bias point to process variations. Self-biased operational amplifiers are free from the above mentioned drawbacks and exhibit the same performance as existing folded casode operational amplifiers, except for a small reduction in slew rate. This thesis work is for the development of new trend of operational amplifier. The technology is shrinking down, portability of electronic systems is gaining more important. With the technology shrinking threshold voltage is not shrinking with the same proportion. So it is useful for operational amplifier to work at any common mode level so a rail-to-rail input stage is a better choice for an operational amplifier. A rail-to-rail input common mode range is an important requirement in operational amplifiers for some applications. Conventional techniques to achieve a constant-gm rail-to-rail complementary N-P differential input stage require complex additional circuitry. In addition, the frequency response and common-mode rejection ratio (CMRR) are degraded. The technique used here in this thesis work is generating a voltage source between source terminals of both N and P differential pair, which keeps effective gate source voltage hence gm constant over the whole rail-to-rail common mode level. Finally, a self biased rail-to-rail input operational amplifier is designed using TSMC 0.35 m μ CMOS technology with a supply voltage of 3.3V. As the input common mode varies, variation in DC gain is up to 3.65dB. The power dissipation of the operational amplifier is 268.5 W μ with unity gain bandwidth 9.17MHz and phase margin of 54.94o. Further process corner simulations have been done for process variation of 15% in threshold voltage TH V , oxide thickness ox t and mobility 0 μ . Variation in gain in this process variation is 84.5588 dB to 86.2154 dB which is very less. And power dissipation variation from 44.549 W μ to around 1 mW.
