SELECTION AND CLASSIFICATION METHODS FOR DETECTING IMAG- INATION MOVEMENT AND SPONTANEOUS EEG SIGNALS: A STUDY OF METHODOLOGIES

The incorporation of pattern recognition tech- niques into Brain Computer Interface (BCI) systems has become an essential and promising field of research. This article analyzes and compares two new methodologies for classification of BCI signal into spontaneous and im- aginary movements. Such methodologies are based on a combination of a feature selection technique with a learn- ing algorithm. Comparing the results obtained in this study with those found in the literature, it can be said that they are similar with average success rate around 80 % and 90 % (8, 10-12).
Nutritional Assessment of Some Land and Water Snail Species in Delta State , Nigeria

Proximate and mineral analyses were carried out on three land snails in Delta State (Archachatina marginata ovum, Archachatina marginata saturalis and Limicolaria spp) and two fresh water (Lanistes varicus and Nucella lapillus) snail species for nutritional assessment using their muscular foot tissues. The mean of crude protein ranged from 70.00 ± 0.03 in Lanistes varicus to 84.43 ± 0.01% in Archachatina marginata ovum and moisture content of 73.69 ± 0.01 in Nucella lapillus to 80.78 ± 0.06% in Archachatina marginata ovum were obtained. The water snails had significantly (P < 0.05) higher crude fibre than the land snails. Values as low as 0.50 ± 0.02 crude fibre were obtained in Archachatina marginata ovum while Nucella lapillus had the highest value of 1.50± 0.01. Mineral analysis of the snail species revealed relatively high amount of minerals in the water snails compared to the land snails. Calcium values of 172.79 ± 0.01 in Limicolaria spp to 182.70 ± 0.02mg /100g in Nucella lapillus were obtained. Phosphorus ranged from 51.49 ± 0.01 in Archachatina marginata saturalis to 62.52± 0.01 mg/100g in Lanistes varicus and Iron content ranged from 6.79 ± 0.06 in Archachatina marginata ovum to 11.09 ± 0.01mg/ 100g in Nucella lapillus with low zinc content of 1.14 ± 0.01 in Limicolaria spp. to 1.32± 0.01mg/100g in Nucella lapillus. This research therefore, encourages increase in production and consumption of snail species especially Archachatina marginata ovum based on its high crude protein content and size.
Distributed architectures and logical-task decomposition in multimedia surveillance systems

In the past few years, the development of complex surveillance systems has captured the interest of both the research and industrial worlds. Strong and challenging requirements of modern society are involved in this problem, which aims to increase safety and security in several application domains such as transport, tourism, home and bank security, military applications, etc. At the same time, fast improvements in microelectronics, telecommunications, and computer science make it necessary to consider new perspectives in this field. The main objective of this paper is to investigate, discuss, and evaluate the impact of distributed processing and new communication techniques on multimedia surveillance systems, which represent the so-called third-generation surveillance systems (3 GSSs). In particular, aspects related to the distribution of intelligence among multiple-processing and wide-bandwidth resources are discussed in detail. It is shown how distribution of intelligence can be obtained by a hierarchical architecture that partitions, in a dynamic way, the main logical processing tasks (i.e., representation, recognition, and communication) performed in a 3 GSS physical architecture made up of intelligent cameras, hubs, and central control rooms. The advantages of this solution are pointed out in terms of 1) increased flexibility and reconfigurability and 2) optimal allocation of available processing and bandwidth resources. Finally, a case study is analyzed that allows one to gain a deeper insight into a distributed surveillance system.
A Diagnostic Dilemma in a Rare Presentation of Neurosarcoidosis : A Case Report

Sarcoidosis is a multisystem granulomatous disease of unknown etiology which has a tendency for involvement of lungs. But in around 30-35% of cases, patients can present with extrathoracic manifestations of the disease [1-3]. Diagnosis of extrapulmonary sarcoidosis presents a challenge to health care providers and is often delayed in as many as 50% of cases, especially when there is an isolated extrapulmonary organ involvement [2]. Also, certain extrapulmonary sarcoid features are more common than others. Of the patients that present with extrathoracic manifestations of sarcoidosis, only around 5-10% have clinical involvement of the nervous system [46]. Furthermore, these neurologic symptoms vary in presentation in different patients, further obscuring the diagnosis.
The Influence of Representation by Works Councils on Organizational Performance of Government Health Care Institutions in Kenya

The influence of representation by works councils has been identified in research to promote organizational commitment, employee job satisfaction and improved individual productivity which in turn leads to organizational performance. The lack of representation by works councils has been identified as the major factor perpetuating strikes and lack of commitment of health workers. This has resulted in loss of lives in the hospitals and poor health services. This study aimed at assessing the influence of representation by works councils on organizational performance among health workers in Kenya. Descriptive survey design was adopted in conducting the study and Stratified sampling techniques was employed to select 384 employees from the selected Kiambu and Machakos Level 5 hospitals as well as Kenyatta National Hospital as the respondents to the study. A response of 87.5% was achieved and both primary and secondary data was used for the study. Questionnaires and interview guides were used as data collection instruments. Data was analyzed using qualitative and quantitative procedure. In addition, a multiple linear regression model was applied to examine the relationship between the variables. SPSS version 24 was used for data analysis and generation of tables, figures and relationships. In conclusion, representation by works councils/trade unions was found to influence organizational performance in Kenya. The study recommends that the management should seek to keep workers and problems separate so as to enable real issues to be debated without damaging working relationships. By listening carefully and paying attention to the interests presented by employees, management will most likely understand them. Workers as well can seek more advice and assistance from trade unions in advocating for their rights and management should not punish their works for joining relevant work councils relevant to them. The study recommends further study on private health institutions to confirm and validate the theories and findings.
Identifikasi Fitur Wajah Dengan Menggunakan Facial Points Dan Euclidean Distance

: Face recognition currently is one of the research which keeps on developing notably used in security field. There are unique features on each human face which differs one from another. This research identify the face features by combining Facial Points and Euclidean distance method. The used data is obtained from the webcam which was acquired into 2D format as much as 3 reference images and 15 trial images from 3 people. Facial Points method using Viola Jones and labelling facial feature points in some of face features such as eyes, nose, and mouth is relatively acquired in more faster, accurate and efficient results in detecting the face features. Every feature is measured its ratio towards reference features using Euclidean Distance to explore the closest distance. In this research, the identification using Euclidean Distance acquired system accuracy value in face recognition as much as 80 percent. Other results obtained is the focused face position exposed to light determines the success of face detection.

The Altered Somatic Brain Network in State Anxiety

Highly anxious individuals often show excessive emotional arousal, somatic arousal, and characteristics of mental illness. Previous researches have extensively investigated the emotional and cognitive biases of individuals with high anxiety, but overlooked the spontaneous brain activity and functional connections associated with somatic arousal. In this study, we investigated the relationship between state anxiety and the spontaneous brain activity of the somatosensory cortex in a non-clinical healthy population with state anxiety. Furthermore, we also explored the functional connections of the somatosensory cortex. We found that state anxiety was positively correlated with the amplitude of low-frequency fluctuations (ALFFs) of somatic related brain regions, including the right postcentral gyrus (somatosensory cortex) and the right precentral gyrus (somatic motor cortex). Furthermore, we found that state anxiety was positively correlated with the connections between the postcentral gyrus and the left cerebellum gyrus, whereas state anxiety was negatively correlated with the connectivity between the postcentral gyrus and brain regions including the left inferior frontal cortex and left medial superior frontal cortex. These results revealed the association between the anxious individuals’ body-loop and state anxiety in a healthy population, which revealed the importance of somatic brain regions in anxiety symptoms and provided a new perspective on anxiety for further study.
Microcirculatory Differences in Children With Congenital Heart Disease According to Cyanosis and Age

Background: Congenital heart disease (CHD) is one of the main causes of morbidity and mortality in children. Microcirculatory changes in CHD patients have previously been investigated using a variety of techniques. Handheld videomicroscopy enables non-invasive direct visualization of the microcirculatory bed. The aim of our study was to determine if there are microcirculatory differences among CHD patients based on age and the presence of cyanosis. Methods: A prospective observational study was carried out. Patients with CHD undergoing corrective surgery were evaluated after anesthetic induction prior to surgery. Microcirculation was evaluated using sidestream dark field (SDF) imaging. Hemodynamics and respiratory, biochemical, and tissue perfusion parameters were analyzed. Results: A total of 30 patients were included, of whom 14 were classified as cyanotic and 16 as non-cyanotic. Cyanotic patients had a higher total vessel density (TVD) (p = 0.016), small vessel density (p = 0.004), and perfused small vessel density (p = 0.013), while their microvascular flow index (MFI) was lower (p = 0.013). After adjustment for age and PaO2, cyanotic patients showed increased TVD (p = 0.023), and small vessel density (p = 0.025) compared to non-cyanotic patients but there were no differences on the MFI. Age was directly correlated with total MFI (spearman's rho = 0.499, p = 0.005) and small vessel MFI (spearman's rho = 0.420, p = 0.021). After adjustment for the type of CHD (cyanotic vs. non-cyanotic) patients with MFI and small MFI vessels <3 were younger than those with values ≥3 (p = 0.033 and p = 0.037). Conclusions: SDF-based evaluation of microcirculation in CHD patients showed that patients with cyanotic defects had higher vascular density, as compared to patients with non-cyanotic defects. Younger patients were more likely to have a low MFI regardless of their type of CHD.
Building capacity for librarian support and addressing collaboration challenges by formalizing library systematic review services

Background Many health sciences librarians are noticing an increase in demand for systematic review support. Developing a strategic approach to supporting systematic review activities can address commonly reported barriers and challenges including time factors, methodological issues, and supporting student-led projects. Case Presentation This case report describes how a health sciences library at a mid-sized university developed and implemented a structured and defined systematic review service in order to build capacity for increased librarian support and to maximize librarians’ time and expertise. The process also revealed underlying collaboration challenges related to student-led systematic reviews and research quality concerns that needed to be addressed. The steps for developing a formal service included defining the librarian’s role and a library service model, building librarian expertise, developing documentation to guide librarians and patrons, piloting and revising the service model, marketing and promoting the service, and evaluating service usage. Conclusions The two-tiered service model developed for advisory consultation and collaboration provides a framework for supporting systematic review activities that other libraries can adapt to meet their own needs. Librarian autonomy in deciding whether to collaborate on reviews based on defined and explicit considerations was crucial for maximizing librarians’ time and expertise and for promoting higher quality research. Monitoring service usage will be imperative for managing existing and future librarian workload. These data and tracking of research outputs from librarian collaborations may also be used to advocate for new librarian positions.
Professional development in evidence-based practice: course survey results to inform administrative decision making

Objective To understand librarians’ evidence-based practice (EBP) professional development needs and assist library administrators with professional development decisions in their own institutions, the study team surveyed past participants of an EBP online course. This study aimed to (1) understand what course content participants found valuable, (2) discover how participants applied their course learning to their work, and (3) identify which aspects of EBP would be beneficial for future continuing education. Methods The study team distributed an eighteen-question survey to past participants of the course (2011–2017). The survey covered nontraditional demographic information, course evaluations, course content applications to participants’ work, additional EBP training, and EBP topics for future CE opportunities. The study team analyzed the results using descriptive statistics. Results Twenty-nine percent of course participants, representing different library environments, responded to the survey. Eighty-five percent of respondents indicated that they had prior EBP training. The most valuable topics were searching the literature (62%) and developing a problem, intervention, comparison, outcome (PICO) question (59%). Critical appraisal was highly rated for further professional development. Fifty-three percent indicated change in their work efforts after participating in the course. Ninety-seven percent noted interest in further EBP continuing education. Conclusions Survey respondents found value in both familiar and unfamiliar EBP topics, which supported the idea of using professional development for learning new concepts and reinforcing existing knowledge and skills. When given the opportunity to engage in these activities, librarians can experience new or expanded EBP work roles and responsibilities. Additionally, the results provide library administrators insights into the benefit of EBP professional development.
VLSI implementation of a 32-bit Kozen formulation Ladner/Fischer parallel prefix adder

As modern processors' word lengths increase and clock cycle times get shorter, it becomes more and more important to have basic arithmetic functions which can be used without becoming a bottleneck. The parallel prefix adder has depth O(log n) and area O(n). Since the parallel prefix adder has a regular structure with very limited fan-out, it is ideally suited for use in VLSI applications.
A Data Provenance Model for Collaboration Design Process

Data provenance is the basic metadata for process analysis in process aware system and plays an important role in collaboration design process for process auditing and process improvement, but data collaboration and iterative processin theexecutionof collaboration design process impede the integrity of provenance tracking based on data provenance. This paper proposes a collaborative design provenance model based on OPM, which can support provenance tracking in the execution of multiple related collaboration design processes. In this model, it descripts the basic characteristic of the execution of collaboration design process, supports the description of iterative process by execution path expansion, and supports the descriptions of different data collaboration patternsbetween different design processes. Based on this model, we finally provide the global data provenance directed graph by the mechanism of data provenance sharing and combination that can insure the integrity of provenance tracking of collaboration design process.
Giant vortex clusters in a two-dimensional quantum fluid

Clustering vortices Many-body systems generally become more disordered as more energy is pumped into them. A curious exception to this rule was predicted in the context of turbulent flow by the physical chemist Lars Onsager. He suggested that the entropy of certain two-dimensional (2D) systems can decrease with increasing energy, corresponding to an effective negative temperature. Using 2D Bose-Einstein condensates of atoms, Gauthier et al. and Johnstone et al. put Onsager's theory to the test. They provided energy to the system by perturbing the condensate, creating vortices and antivortices. With increasing energy, the system became more ordered as clusters containing either only vortices or only antivortices emerged. Science, this issue p. 1264, p. 1267 2D Bose-Einstein condensates are used to reach the vortex clustering regime in Onsager’s model of turbulent flow. Adding energy to a system through transient stirring usually leads to more disorder. In contrast, point-like vortices in a bounded two-dimensional fluid are predicted to reorder above a certain energy, forming persistent vortex clusters. In this study, we experimentally realize these vortex clusters in a planar superfluid: a 87Rb Bose-Einstein condensate confined to an elliptical geometry. We demonstrate that the clusters persist for long time periods, maintaining the superfluid system in a high-energy state far from global equilibrium. Our experiments explore a regime of vortex matter at negative absolute temperatures and have relevance for the dynamics of topological defects, two-dimensional turbulence, and systems such as helium films, nonlinear optical materials, fermion superfluids, and quark-gluon plasmas.
A soft ring oscillator

An elastomeric device converts a constant input pressure into multiple oscillating, temporally offset output pressures. Periodic actuation of multiple soft, pneumatic actuators requires coordinated function of multiple, separate components. This work demonstrates a soft, pneumatic ring oscillator that induces temporally coordinated periodic motion in soft actuators using a single, constant-pressure source, without hard valves or electronic controls. The fundamental unit of this ring oscillator is a soft, pneumatic inverter (an inverting Schmitt trigger) that switches between its two states (“on” and “off”) using two instabilities in elastomeric structures: buckling of internal tubing and snap-through of a hemispherical membrane. An odd number of these inverters connected in a loop produces the same number of periodically oscillating outputs, resulting from a third, system-level instability; the frequency of oscillation depends on three system parameters that can be adjusted. These oscillatory output pressures enable several applications, including undulating and rolling motions in soft robots, size-based particle separation, pneumatic mechanotherapy, and metering of fluids. The soft ring oscillator eliminates the need for hard valves and electronic controls in these applications.
Impact-resistant nacre-like transparent materials

Nacre-inspired toughened glass Nacre is a biological composite that is present in seashells. This composite contains a small amount of organic material that toughens brittle ceramics, such that a highly regular three-dimensional brick-and-mortar assembly of microscopic mineral tablets is bonded together with biopolymers. Synthetic nacres have not been able to capture the large-scale sliding of the bricks that is key to enhancing toughness. Yin et al. applied this model to toughening glass, where square or hexagonal borosilicate glass sheets were bonded together using ethylene-vinyl acetate interlayers (see the Perspective by Datsiou). This generated a structure that allows glass plates to slide past each other. The resulting five-layered glass composite was deformable and impact resistant, while maintaining high stiffness, flexural strength, surface hardness, and transparency. Science, this issue p. 1260; see also p. 1232 A ductile, yet hard, nacre-inspired glass outperforms laminated glass and tempered glass in impact resistance. Glass has outstanding optical properties, hardness, and durability, but its applications are limited by its inherent brittleness and poor impact resistance. Lamination and tempering can improve impact response but do not suppress brittleness. We propose a bioinspired laminated glass that duplicates the three-dimensional “brick-and-mortar” arrangement of nacre from mollusk shells, with periodic three-dimensional architectures and interlayers made of a transparent thermoplastic elastomer. This material reproduces the “tablet sliding mechanism,” which is key to the toughness of natural nacre but has been largely absent in synthetic nacres. Tablet sliding generates nonlinear deformations over large volumes and significantly improves toughness. This nacre-like glass is also two to three times more impact resistant than laminated glass and tempered glass while maintaining high strength and stiffness.
