Performance comparison of antenna deployment cases and precoding schemes in an ultra-dense scenario for high SHF wide-band massive MIMO in 5G

: Multiuser multiple-input multiple-output (MU-MIMO) downlink technology over massive MIMO is a key enabler for 5G systems and beyond. However, its performance may deteriorate when users are spatially correlated. Distributed antenna deployment (DAD) and nonlinear precoding (NLP) have been studied as countermeasures for this issue. In this paper, through simulations of 28 GHz-band massive MIMO downlink transmission in an ultra-dense urban scenario, it is revealed that, rather than DAD, concentrated antenna deployment (CAD) is more robust against channel transition issues up to walking speed. It is also found that combining CAD with NLP provided the best throughput performance in the evaluated scenario.
Postural changes versus balance control and falls in community-living older adults: a systematic review

Abstract Introduction: Since falls are considered to be a public health problem, it is important to identify whether postural changes over time contribute to the risk of falls in older adults. Objective: To investigate whether postural changes increase fall risk and/or postural imbalance in healthy, community-dwelling older adults. Methods: In April 2016, two reviewers independently searched the PubMed, Web of Science, SPORTDiscus, and CINAHL databases for studies in English published in the previous 10 years, using the following combined keywords: “posture” or (“kyphosis”,“lumbar lordosis”,“flexed posture”,“spinal curvature”,“spinal sagittal contour”) AND “elderly” AND “fall”. Study quality was assessed according to the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) guidelines for observational studies. Results: The search retrieved 1,734 articles. Only observational studies that assessed posture, balance, and/or falls in older adults were considered eligible for review. The final sample included 17 articles: reliability and reproducibility of the instruments were not reported in five studies, while two studies offered a questionable description of the instruments used. Fourteen articles analyzed postural changes at the trunk level and three articles assessed them at the ankles and feet. Most studies found a positive association between postural changes and an increased risk for loss of balance and falls. Conclusion: Thoracic hyperkyphosis, loss of lumbar lordosis, and decreased plantar arch seem to contribute to greater postural instability, and thus to a higher risk of falls in community-living older adults.
Non-Trivial Off-Path Network Measurements without Shared Side-Channel Resource Exhaustion

Most traditional network measurement scans and attacks are carried out through the use of direct, on-path network packet transmission. This requires that a machine be on-path (i.e., involved in the packet transmission process) and as a result have direct access to the data packets being transmitted. This limits network scans and attacks to situations where access can be gained to an on-path machine. If, for example, a researcher wanted to measure the round trip time between two machines they did not have access to, traditional scans would be of little help as they require access to an on-path machine to function. Instead the researcher would need to use an off-path measurement scan. Prior work using network side-channels to perform off-path measurements or attacks relied on techniques that either exhausted the shared, finite resource being used
Light-modulation of corticular CO2-refixation in young birch stems (Betula pendula Roth.)

(212). Photosynthetic bark reduces the flux of CO 2 from woody tissues to the atmosphere by recycling endogenous CO 2 derived from mitochondrial respiration. In young birch trees (Betula pendula Roth.) this process is modulated by the light intensity regime at the growing site. Although positive net photosynthesis was not yet found in intact birch twigs, CO 2 efflux was distinctly reduced upon illumination by 65% in high-light grown birches (HL: 100% sunlight) and by up to 82% in low-light grown trees (LL: 20% of full sunlight). Bark chlorenchymes were found to be optimized for light harvesting and photosynthetic performance under LL-conditions, due to the shading effect of the outer peridermal (or rhytidomal) layers. Compared on a unit area basis the inner bark tissue contained up to 47%-49% of the chlorophyll of the concomitant leaves under both HL and LL conditions, respectively. Peridermal light transmittance was changed by the light intensity regime during growth, due to changes within the microstructure of the outer bark. The inner bark morphology, quantified as specific bark area (SBA), was found to be strongly correlated with twig respiration (r2 = 0.83-0.96) and the CO 2 -refixation rate (r2 = 0.81-0.95) under LL and HL conditions and thus can be used to predict the efflux of CO 2 from the stem organs. Besides leaf dark respiration (R d ) also twig R d was clearly related with the light environment. Under shading the investigated twigs showed a lower Rd but a higher relative CO 2 -refixation (expressed as a percentage of dark respiration); up to 100% of the respired carbon was refixed in LL twigs. Furthermore, twig R d was the physiological parameter that correlated most strongly with CO 2 -refixation rate.
FRI0552 Sm04690, a wnt pathway inhibitor: anti-inflammatory and cartilage protective effects in preclinical oa models

Background Osteoarthritis (OA) is characterised by pain, swelling, and reduced function in the knee joint. Upregulated Wnt signalling drives OA through synovial inflammation, increased subchondral bone, and thinning cartilage. Objectives SM04690, a small molecule Wnt pathway inhibitor that demonstrated chondrogenic and anti-inflammatory properties preclinically1, was further evaluated to determine its potential to reduce inflammation, protect cartilage, improve joint health and modify pain in OA. Methods Cytokine secretion (IL-6 and TNF-α) from IL-1β-stimulated and SM04690-treated synovial fibroblasts was measured by ELISA. A single intra-articular injection of SM04690 or vehicle was evaluated in an in vivo rat knee monosodium iodoacetate (MIA) OA model. Joint inflammation was evaluated by H and E staining, inflammatory cytokines (IL-1α, IL-1β, IL-6, TNF-α and IFN-γ) by qPCR, and cartilage protection by qPCR for matrix metalloproteinases (MMPs). Histological evaluation of cartilage health was performed using OARSI score and thickness by Safranin-O staining. Pain was measured as paw withdrawal threshold using Von Frey apparatus and weight distribution using incapacitance metre and analysed using generalised estimating equation regression. Results SM04690 dose-dependently inhibited IL-1β-induced cytokine secretion in synovial fibroblasts (EC50 ~30 nM; figure 1). In the rat MIA OA model, compared to vehicle, SM04690 injection reduced visible knee swelling, inflammatory cells, and proinflammatory cytokine and MMP production (p<0.05). SM04690 increased (p<0.01) paw withdrawal threshold from day 6 and improved weight distribution to the affected limb in treated rats, at multiple timepoints, compared to vehicle (figure 2). SM04690 increased Safranin-O stained cartilage thickness and decreased OARSI score (p<0.05) compared to vehicle.Abstract FRI0552 – Figure 1 SM04690 inhibited inflammatory cytokine production in synovial fibroblasts in vitroAbstract FRI0552 – Figure 2 SM04690 inhibited inflammatory cytokine production and decreased inflammation and pain in the MIA model of OA Conclusions In a rat MIA OA model, SM04690 injection reduced inflammation, protease production, and pain, with improved cartilage and joint health, compared to vehicle. Previously demonstrated regenerative effects in nonclinical studies1, along with anti-inflammatory properties, show SM04690 may improve symptoms and potentially provide disease modification in OA.

Occlusion-aware Multifocal Displays

The goal of three-dimensional (3D) displays is to recreate reality by satisfying all perceptual cues used by the human visual system. While many perceptual cues can be replicated by showing 2D images to our eyes, the accommodation cue, or the change of the focal length of the ocular lens, is very difficult to satisfy with today’s 3D displays. This inability to support the focusing of the eyes causes a problem called the vergence-accommodation conflict, which results in visual discomfort after long periods of use. Multifocal displays satisfy the accommodation cue by displaying content on multiple virtual planes, each at a different depth. However, current designs of multifocal displays suffer from a limited number of focal planes and their inability to block light. The small number of focal planes significantly reduces the supported depth range of multifocal displays. The light leaking from the far focal planes also dramatically reduces the contrast of the image formed on the retina and weakens the occlusion cue — anotherimportant perceptual cue used by the human visual system to estimate depth. This dissertation focuses on solving the two limitations of multifocal displays — the paucity of focalplanes and the weak occlusion cue. Specifically, we design and build a multifocal display that can generate a dense focal stack — with an order of magnitude increase in the number of focal planes over existing works. To create proper occlusion cues, we endow multifocal displays with a novel capability to tilt the light emitted by each pixel. We showthat the capability enables multifocal displays to generate occlusion cues without losing spatial resolution. The dissertation also contributes to the theoretical understandingof multifocal displays. We analyze the domain of light fields that can be generated by multifocal displays and characterize multifocal displays in terms of their depth-of-field, spatial resolution, and the required number of focal planes. The proposed methods enable natural accommodation and occlusion cues that are critical for animmersive virtual world. Virtual and augmented reality (VR/AR) devices stand to benefit significantlyfrom the advancements made in the dissertation. Moreover, all of the proposed methods require only simple modifications to existing AR/VR displays and are computationally and bandwidth-efficient. In this sense, the technologies are timely and could pave the way to a more immersive AR/VR experience.
Effect of LEDs on flower bud induction in Chrysanthemum morifolium cv. Zembla

The effect of LEDs was studied to induce flower under artificial long days (LD) in Chrysanthemum morifolium cv. Zembla plants, using light emitting diodes (LED) @ PAR m-2 s-1 80% Red / 20% Blue maintained @ 100 µ mol m- 2 s- 1 using royal blue light @ 455 nm and red light @ 640 nm wavelengths and compared with short day (SD) length. Difference in growth and flowering response were also investigated. Stem length is determined as a function of internode length which could be the function of attaining minimum number of leaves required for expressing the diurnal response using LEDs. Chrysanthemum plants exhibited a strong diurnal response attained in leaves and transmitted to the apex and took minimum (28 days) and maximum time (61 days) with an exposure to LEDs with (15h) and without (11h) additional blue spectrum, respectively. However, bud induction was possible earliest due to low red/far ratio in the extended exposure of plants with blue LEDs.
Data-Driven Human-Centric Web Design: Beyond Tables and Statistics

Conventional web design tends to see tabular data as providing a barrier to creative graphic design. This project explores how such data can be displayed in a more abstract visual format, free from tables and the need to navigate through layers of information. The creative component reported here is the result of a personal exploration based on curriculum taught by the author in an undergraduate interdisciplinary course that merged perspectives from the fields advertising, graphic design and computer science to create personalized data-driven applications. Of particular interest to this project was determining if there are limits to the design elements that can be controlled by live data in a web page displaying weather information. Seven data sources, connected to via application programming interfaces (APIs), were used to bring in 16 location-specific data points relating to weather, population, and geolocation. Literal text-based content displays used some of the data points, while others were used to control various visual elements (e.g., backgrounds, weather condition representations, and animation speeds). The result was a single visual web page displaying current conditions and forecasts using limited text, dynamically applied images, and Cascading Style Sheet (CSS) animations, all of which required minimal user intervention.

Engagement With Live Blogs: When Passive Consumption Overpowers Participation

This study investigated citizen participation in live blogs in the changing media ecosystem from the public sphere perspective. The live blog is a web-native, participatory-oriented journalistic genre comprised of brief updates of an event in motion and designed to deliver real-time information from multiple sources about breaking news and scheduled events. To examine participation in this contemporary news format, the current, exploratory study, collected survey responses from 339 volunteers and found that participation was not a motivating factor for readers to engage in live blogging on a deeper level. Other study findings pertaining to participation were also pessimistic, showing that the majority of participants were not personally interested in participating in live blogging. This is an important finding for digital journalism as it implies that the capacity of online platforms to accommodate participation does not necessarily translate into citizens’ willingness to participate.
Maternal immune activation alters the behavioral, cytokine, and gene expression profiles in rat offspring

Maternal immune activation (MIA) is a risk factor for the development of schizophrenia and autism. The relationship between maternal infection and atypical fetal development is likely mediated by the activation of the maternal immune system, notably with elevated inflammatory cytokines in the fetal environment, but the intervening cellular and molecular links between infection and risk for neuropsychiatric disorders are unknown. The following dissertation addressed the behavioral, immunological, and molecular effects of MIA in the offspring of pregnant Sprague-Dawley rats given an intraperitoneal (0.25 mg/kg) injection of lipopolysaccharide (LPS) on embryonic day 15. In Study 1, the consequences of maternal LPS on postnatal behavioral development were examined. Offspring born to LPS-dams exhibited reduced social preference and exploration behaviors as juveniles and adults. In Study 2, the effects of maternal LPS on cytokine, chemokine, and growth factor protein levels in maternal serum, amniotic fluid, and fetal brain at 4 and 24 h post injection were examined. Across the three compartments, LPS elevated proinflammatory cytokine and chemokine levels at 4 h, and levels decreased but remained elevated at 24 h. The greatest elevations were in serum, followed by amniotic fluid, then fetal brain. Treatment initially reduced anti-inflammatory cytokine levels at 4 h, which could partly explain the sustained cytokine response. Growth factor levels in the fetal brain were reduced at both

Segmentation of Brain Tumor Images Using Genetic Algorithms

31 Segmentation of Brain Tumor Images Using Genetic Algorithms Mohameed Nathem Manar Y. Kashmola Dhuha B. Abdullah Prof.dhuha_basheer@uomosul.edu. iq College of Computer Sciences and Mathematics University of Mosul, Iraq Received on: 20/08/2008 Accepted on: 04/12/2008 ABSTRACT In this research, the brain images resulting from computerized tomography (CT) have been used in order to determine the tumor area in the brain. the steps started by preprocessing operation to the image before inputting it to algorithm . the image was converted to binary image in order to segment the image, later on into equal segments ,then the correlation coefficient was found among these segments ,these values used as fitness function in the genetic algorithm in order to different iate between segments ,the result of the genetic algorithm was segment numbers which will be merged to form the sub-images ,then continuing these steps till determining the tumor approximate location. Another approach of image segmentation has been used without using the genetic algorithm by choosing the segments though a certain condition not randomly. Satisfying results have been reached in both approaches, but in different execution times. In both approaches tumor location was determined approximately, as a result the genetic algorithm was succeeded in about 85% while the first algorithm determine 80% of tumor locations.
Working memory and learning in children: a matter of attention

Memorizing is crucial for human beings because it constitutes the fundamental step in acquiring knowledge. Among the different memory systems, the one called "working memory" works continuously to simultaneously memorize and process information. It is particularly important in children who are continually confronted to learning situations. It has long been considered that memorizing required verbalizing and repeating. The present paper offers an alternative conception: working memory relies on attentional mechanisms constrained by time and do not depend on verbal characteristics. The empirical analyses we present here do not only conduct to important theoretical conclusions, they also give a glimpse of practical applications for preventing school failure.
Toward an epistemology of Wikipedia

Wikipedia (the “free online encyclopedia that anyone can edit”) is having a huge impact on how a great many people gather information about the world. So, it is important for epistemologists and information scientists to ask whether people are likely to acquire knowledge as a result of having access to this information source. In other words, is Wikipedia having good epistemic consequences? After surveying the various concerns that have been raised about the reliability of Wikipedia, this article argues that the epistemic consequences of people using Wikipedia as a source of information are likely to be quite good. According to several empirical studies, the reliability of Wikipedia compares favorably to the reliability of traditional encyclopedias. Furthermore, the reliability of Wikipedia compares even more favorably to the reliability of those information sources that people would be likely to use if Wikipedia did not exist (viz., Web sites that are as freely and easily accessible as Wikipedia). In addition, Wikipedia has a number of other epistemic virtues (e.g., power, speed, and fecundity) that arguably outweigh any deficiency in terms of reliability. Even so, epistemologists and information scientists should certainly be trying to identify changes (or alternatives) to Wikipedia that will bring about even better epistemic consequences. This article suggests that to improve Wikipedia, we need to clarify what our epistemic values are and to better understand why Wikipedia works as well as it does.
Axillary Metastatic Breast Cancer and Tuberculous Lymphadenopathy in Supraclavicular Region

A healthy assessment of the axilla is a basic requirement in the grading of breast cancer and determining the prognosis. Despite all of the imaging techniques at hand, tissue diagnosis remains to be the gold standard in the assessment of axillary lymphadenopathies in cases with a diagnosis of primary breast tumor. With this presentation, we aimed to discuss our case which seemed to be axillary metastatic lymphadenopathy according to imaging techniques, however supraclavicular tuberculosis lymphadenitis was detected simultaneously with axillary metastatic lymphadenopathy.
Fuzzy control of self‐balancing robots: A control laboratory project

This paper presents a novel control laboratory project that provides hands‐on experience in feedback control concepts (embedded control systems) through dedicated assignments, with a particular focus on the design and implementation of fuzzy control. The project is structured around an inexpensive, portable self‐balancing robot (SBR), whose embedded system is realized using commercially available breakout boards as the first assignment. For the stabilization of the plant, students are guided to execute the essential stages of control system design, from system modeling and parameter optimization, over basic or advanced control strategy design in the MATLAB/Simulink environment, to both implementation and validation of the closed loop on the real robot. To demonstrate and foster the application of fuzzy logic, the second part of the paper introduces a simple control strategy based on fuzzy logic controllers. Then, a lookup table‐based implementation technique is described for the demonstration of manual interfacing and embedded coding of fuzzy control strategies. The proposed methods are clear and straightforward; they highly foster the understanding of feedback control techniques and allow students to gain vast knowledge in the practical implementations of control systems.
