An Overview of Massive MIMO Technology Components in METIS

As the standardization of full-dimension MIMO systems in the Third Generation Partnership Project progresses, the research community has started to explore the potential of very large arrays as an enabler technology for meeting the requirements of fifth generation systems. Indeed, in its final deliverable, the European 5G project METIS identifies massive MIMO as a key 5G enabler and proposes specific technology components that will allow the cost-efficient deployment of cellular systems taking advantage of hundreds of antennas at cellular base stations. These technology components include handling the inherent pilot-data resource allocation trade-off in a near optimal fashion, a novel random access scheme supporting a large number of users, coded channel state information for sparse channels in frequency- division duplexing systems, managing user grouping and multi-user beamforming, and a decentralized coordinated transceiver design. The aggregate effect of these components enables massive MIMO to contribute to the METIS objectives of delivering very high data rates and managing dense populations.
Addressing the anti-vaccination movement and the role of HCWs.

Over the last two decades, growing numbers of parents in the industrialized world are choosing not to have their children vaccinated. Trying to explain why this is occurring, public health commentators refer to the activities of an anti-vaccination movement. The aim of this paper is to review the literature about the anti-vaccination movements and to highlight the knowledge and the skills needed for HCWs to fight against their ideas. The main theoretical structures of anti-vaccination ideology in the 19th and 20th centuries are: vaccines cause idiopathic illness; opponents against vaccines accused vaccine partisans to be afraid of the "search after truth," they fear unveiling errors; the vaccination law not only insults every subject of the realm, but also it insults every human being; vaccine immunity is temporary; an alternative healthy lifestyle, personal hygiene and diet stop diseases. Proponents against vaccination now have additional means to communicate their positions to the general public, the Internet in particular. Doctors and HCWs constantly have to face parents and patients who search information about vaccination. A lot of these people have previously found data about vaccinations from a lot of sources, such as papers, media or in websites and in these sources most contents come from anti-vaccine movements. For these reasons doctors and HCWs need to have updated knowledge about the vaccinations and to know the contents proposed by vaccine sceptics. Educating the general public cannot be fully effective unless there is a corresponding provision, enthusiasm and commitment by trained HCWs.
Effects of yoga on cardiovascular disease risk factors: a systematic review and meta-analysis.

The aim of this review was to systematically assess and meta-analyze the effects of yoga on modifiable biological cardiovascular disease risk factors in the general population and in high-risk disease groups.



MEDLINE/PubMed, Scopus, the Cochrane Library, and IndMED were screened through August 2013 for randomized controlled trials (RCTs) on yoga for predefined cardiovascular risk factors in healthy participants, non-diabetic participants with high risk for cardiovascular disease, or participants with type 2 diabetes mellitus. Risk of bias was assessed using the Cochrane risk of bias tool.



Forty-four RCTs with a total of 3168 participants were included. Risk of bias was high or unclear for most RCTs. Relative to usual care or no intervention, yoga improved systolic (mean difference (MD)=-5.85 mm Hg; 95% confidence interval (CI)=-8.81, -2.89) and diastolic blood pressure (MD=-4.12 mm Hg; 95%CI=-6.55, -1.69), heart rate (MD=-6.59 bpm; 95%CI=-12.89, -0.28), respiratory rate (MD=-0.93 breaths/min; 95%CI=-1.70, -0.15), waist circumference (MD=-1.95 cm; 95%CI=-3.01, -0.89), waist/hip ratio (MD=-0.02; 95%CI=-0.03, -0.00), total cholesterol (MD=-13.09 mg/dl; 95%CI=-19.60, -6.59), HDL (MD=2.94 mg/dl; 95%CI=0.57, 5.31), VLDL (MD=-5.70 mg/dl; 95%CI=-7.36, -4.03), triglycerides (MD=-20.97 mg/dl; 95%CI=-28.61, -13.32), HbA1c (MD=-0.45%; 95%CI=-0.87, -0.02), and insulin resistance (MD=-0.19; 95%CI=-0.30, -0.08). Relative to exercise, yoga improved HDL (MD=3.70 mg/dl; 95%CI=1.14, 6.26).



This meta-analysis revealed evidence for clinically important effects of yoga on most biological cardiovascular disease risk factors. Despite methodological drawbacks of the included studies, yoga can be considered as an ancillary intervention for the general population and for patients with increased risk of cardiovascular disease.
CEN@Amrita FIRE 2016: Context based Character Embeddings for Entity Extraction in Code-Mixed Text

This paper presents the working methodology and results on Code Mix Entity Extraction in Indian Languages (CMEE-IL) shared the task of FIRE-2016. The aim of the task is to identify various entities such as a person, organization, movie and location names in a given code-mixed tweets. The tweets in code mix are written in English mixed with Hindi or Tamil. In this work, Entity Extraction system is implemented for both Hindi-English and Tamil-English code-mix tweets. The system employs context based character embedding features to train Support Vector Machine (SVM) classifier. The training data was tokenized such that each line containing a single word. These words were further split into characters. Embedding vectors of these characters are appended with the I-O-B tags and used for training the system. During the testing phase, we use context embedding features to predict the entity tags for characters in test data. We observed that the cross-validation accuracy using character embedding gave better results for Hindi-English twitter dataset compare to TamilEnglish twitter dataset.

A Case Study into the Development Process of Cyber Physical Systems

For the past several years, Cyber Physical Systems (CPS) have emerged as a new system type like embedded systems or information systems. CPS are highly context-dependent, observe the world through sensors, act upon it through actuators, and communicate with one another through powerful networks. It has been widely argued that these properties pose new challenges for the development process.  Yet, how these CPS properties impact the development process has thus far been subject to conjecture. An investigation of a development process from a cyber physical perspective has thus far not been undertaken.  In this paper, we conduct initial steps into such an investigation. We present a case study involving the example of a software simulator of an airborne traffic collision avoidance system.  The goal of the case study is to investigate which of the challenges from the literature impact the development process of CPS the most.
Coordinated Interactions between Hippocampal Ripples and Cortical Spindles during Slow-Wave Sleep

Sleep is characterized by a structured combination of neuronal oscillations. In the hippocampus, slow-wave sleep (SWS) is marked by high-frequency network oscillations (approximately 200 Hz "ripples"), whereas neocortical SWS activity is organized into low-frequency delta (1-4 Hz) and spindle (7-14 Hz) oscillations. While these types of hippocampal and cortical oscillations have been studied extensively in isolation, the relationships between them remain unknown. Here, we demonstrate the existence of temporal correlations between hippocampal ripples and cortical spindles that are also reflected in the correlated activity of single neurons within these brain structures. Spindle-ripple episodes may thus constitute an important mechanism of cortico-hippocampal communication during sleep. This coactivation of hippocampal and neocortical pathways may be important for the process of memory consolidation, during which memories are gradually translated from short-term hippocampal to longer-term neocortical stores.
Submitted as part of TTIC 31210 Advanced Natural Language Processing , Spring 2017 CONTEXT-SENSITIVE PREDICTION OF HASKELL TYPE SIGNATURES FROM NAMES

Identifiers in programs contain semantic information that might be leveraged to build tools that help programmers write code. This work explores using RNN models to predict Haskell type signatures given the name of the entity being typed. A large corpus of real-world type signatures is gathered from online sources for training and evaluation. In real-world Haskell files, the same type signature is often immediately repeated for a new name. To attempt to take advantage of this repetition, a varying attention mechanism was developed and evaluated. The RNN models explored show some facility at predicting type signature structure from the name, but not the entire signature. The varying attention mechanism provided little gain.
An Efficient Approach for Optimizing Frequency Reconfigurable Pixel Antennas Using Genetic Algorithms

In this paper we describe a method for optimizing frequency reconfigurable pixel antennas. The method utilizes a multi-objective function that is efficiently computed by using only one full electromagnetic simulation in the entire genetic algorithm optimization process. Minimization of the number of switches in the design is also attempted. The method is demonstrated using an antenna structure consisting of a rectangular grid of pixels adjacent to a ground plane and using RF MEMS switches for achieving the reconfigurability. The effects of the RF MEMS switches on the antenna performance as well as the control feed lines for them are also addressed. We provide both simulation and experimental results for a reconfigurable dual-band antenna that reconfigures the bands 820-1140 and 1720-1900 MHz to the bands 860-1160 and 1890-2300 MHz with dimensions of 39 mm × 24 mm on a ground plane of 40 mm × 65 mm with one switch only. The results demonstrate that reconfigurable antennas can be designed effectively with a minimum number of switches using an efficient optimization method.
Life on the edge: hydrogen sulfide and the fish communities of a Mexican cave and surrounding waters

Most eucaryotic organisms classified as living in an extreme habitat are invertebrates. Here we report of a fish living in a Mexican cave (Cueva del Azufre) that is rich in highly toxic H2S. We compared the water chemistry and fish communities of the cave and several nearby surface streams. Our study revealed high concentrations of H2S in the cave and its outflow (El Azufre). The concentrations of H2S reach more than 300 μM inside the cave, which are acutely toxic for most fishes. In both sulfidic habitats, the diversity of fishes was heavily reduced, and Poecilia mexicana was the dominant species indicating that the presence of H2S has an all-or-none effect, permitting only few species to survive in sulfidic habitats. Compared to habitats without H2S, P. mexicana from the cave and the outflow have a significantly lower body condition. Although there are microhabitats with varying concentrations of H2S within the cave, we could not find a higher fish density in areas with lower concentrations of H2S. We discuss that P. mexicana is one of the few extremophile vertebrates. Our study supports the idea that extreme habitats lead to an impoverished species diversity.
Balance-Compensated Asymmetric Marchand Baluns on Silicon for MMICs

The balance compensating techniques for asymmetric Marchand balun are presented in this letter. The amplitude and phase difference are characterized explicitly by S21 and S31, from which the factors responsible for the balance compensating are determined. Finally, two asymmetric Marchand baluns, which have normal and enhanced balance compensation, respectively, are designed and fabricated in a 0.18 μm CMOS technology for demonstration. The simulation and measurement results show that the proposed balance compensating techniques are valid in a very wide frequency range up to millimeter-wave (MMW) band.
Nurse-led clinics as an effective service for cardiac patients: results from a systematic review.

The article summarises results of a systematic review on the effectiveness of nurse-led clinics for patients with coronary heart disease. The objective was to present the best available evidence related to effective interventions in nurse-led cardiac clinics including patient education, risk factor assessment and continuity of care.



Following the principles of the Cochrane Collaboration for systematic reviews on effectiveness, this is an update to a previously published review. Thirty databases, relevant journals and hand searching of reference lists were the basis for a comprehensive literature search for the period September 2002 to March 2008. Assessment of methodological quality, data extraction and synthesis was undertaken using a systematic review management tool (JBI-SUMARI). When possible, data was pooled in a meta-analysis.



The systematic review is based on seven randomised controlled trials. Inconsistencies of interventions executed in nurse-led clinics and various effects on the outcomes make a comparison difficult. The major nurse-led intervention applied in the clinics consisted of health education, counselling behaviour change and promotion of a healthy lifestyle. There were no harmful effects on patients with coronary heart disease identified when exposed to a nurse-led clinic. A few risk factors were significantly reduced in the short term by attending nurse-led clinics, but long-term changes were less apparent. The success of modifying behaviour such as smoking cessation and diet adherence was limited. However, nurse-led clinics may positively influence perceived quality of life and general health status.



The results indicated that care was equivalent to non-nurse-managed clinics, and there was no greater risk of poorer outcomes in the nurse-led clinics. The effectiveness of clinics might be dependent on the intensity of the nursing support. Before establishing a nurse-led clinic appropriate qualification and responsibilities, as well as the particular structure of the healthcare system and funding possibilities have to be considered. The combination of counselling and regular assessment of risk factors and health status delivered at nurse-led clinics is supported by the available research, and given that outcomes were in general equivalent between nurse-led and other clinics, further research should investigate the cost-effectiveness of the different models of care.
Research on Presence in Virtual Reality: A Survey

Virtual Reality (VR) is starting to be used in psychological therapy around the world. However, a thorough understanding of the reason why VR is effective and what effect it has on the human psyche is still missing. Most research on this subject is related to the concept of presence. This paper gives an up-to-date overview of research in this diverse field. It starts with the most prevailing definitions and theories on presence, most of which attribute special roles for the mental process of attention and for mental models of the virtual space. A review of the phenomena thought to be effected by presence shows that there is still a strong need for research on this subject because little conclusive evidence exists regarding the relationship between presence and phenoma such as emotional responses to virtual stimuli. An investigation shows there has been substantial research for developing methods for measuring presence and research regarding factors that contribute to presence. Knowledge of these contributing factors can play a vital role in development of new VR applications, but key knowledge elements in this area are still missing.
Effect of 21 days of horizontal bed rest on behavioural thermoregulation

The present study investigated the effect of 21 days of horizontal bed rest on cutaneous cold and warm sensitivity, and on behavioural temperature regulation. Healthy male subjects (N = 10) were accommodated in a hospital ward for the duration of the study and were under 24-h medical care. All activities (eating, drinking, hygiene, etc.) were conducted in the horizontal position. On the 1st and 22nd day of bed rest, cutaneous temperature sensitivity was tested by applying cold and warm stimuli of different magnitudes to the volar region of the forearm via a Peltier element thermode. Behavioural thermoregulation was assessed by having the subjects regulate the temperature of the water within a water-perfused suit (T wps) they were wearing. A control unit established a sinusoidal change in T wps, such that it varied from 27 to 42°C. The subjects could alter the direction of the change of T wps, when they perceived it as thermally uncomfortable. The magnitude of the oscillations towards the end of the trial was assumed to represent the upper and lower boundaries of the thermal comfort zone. The cutaneous threshold for detecting cold stimulus decreased (P < 0.05) from 1.6 (1.0)°C on day 1 to 1.0 (0.3)°C on day 22. No effect was observed on the ability to detect warm stimuli or on the regulated T wps. We conclude that although cold sensitivity increased after bed rest, it was not of sufficient magnitude to cause any alteration in behavioural thermoregulatory responses.
Arrhinencephaly associated with a deficiency involving chromosome 18.

and The Children's Hospital, Birmingham Bilateral harelip, cleft palate, and some form of arrhinencephalic malformation of the brain are among the more common striking features of tri-somy 13-15. These cranio-facial malformations are attributable to a defect of the prechordal meso-derm, and the most extreme form consists of cyclopia associated with a monoventricular brain. The facial and cerebral malformations do not necessarily correspond to each other in severity. For example, in a recent analysis of seven cases of trisomy 13-15, one child (Case 4) showed no cleft of the lip or palate but had an extreme form of monoventricular and Russell, 1966). Arrhinencephaly, with various degrees of involvement of the face and brain, is by no means confined to children with an abnormal karyotype. Landau, Barry, and Koch (1963) described severe cleft lip and palate associated with monoventricular arrhinencephaly in an infant with normal chromosomes. Cebocephaly, one of the more severe forms of this type of malformations, characterized by a single nostril and monoventricular arrhinence-phaly has also been observed with a normal karyo-type (De Myer, 1964). It is probable that such cases are reported less frequently than those with chromosomal abnormalities. N. E. France (personal communication, 1966) found that 4 out of 12 children with various types of arrhinencephaly had normal chromosomes; 6 showed trisomy 13-15, one trisomy 17-18, and one had a deficiency of part of the short arm of chromosome 5. (1963) reported 2 sibs with median harelip, cleft palate, and mono-ventricular arrhinencephaly; the chromosomes of O0 one were examined and showed a normal karyotype. There is general agreement that children with arrhinencephaly and normal chromosomes have few other malformations. This is in contrast to those with trisomy 13-15 where extracephalic malforma-tions are the rule. there have been 12 other reports (Table I). These include 2 with some variety of the arrhinence-phalic type of malformation of the face and brain. This paper described a further case, thus adding to the aetiological significance of the chromosomal deficiency.  This male infant was born 12 days before term to a gravida-2 mother aged 25 years. Pregnancy was uneventful ; deliverywas byforceps because of foetal distress. The baby weighed 2-48 kg. (51 lb.) at birth, and measured 49 5 cm. (191 in.) in length. There was severe bilateral cleft lip and palate, with flattening of the nose, close-set eyes, and unusual configuration of the ears . The skull …
Cu-Sn based joint material having IMC forming control capabilities

This paper describes development of joint materials using only base metals (Cu and Sn) for power semiconductor assembly. The optimum composition at this moment is Cu8wt%Sn92wt% (8Cu92Sn hereafter) particles: pure Cu (100Cu hereafter) particles = 20:80 (wt% ratio), which indicates good stability under Thermal Cycling Test (TCT, −55°C∼+200°C, 20cycles). The composition indicated to be effective to eliminate voids and chip cracks. As an initial choice of joint material using TLPS (Transient Liquid Phase Sintering), we considered SAC305 might have good role as TLPS trigger. But, actual TCT results indicated that existence of Ag must have negative effect to eliminate voids from the joint region. Tentative behavior model using 8Cu92Sn and 100Cu joint material is proposed. Optimized composition indicated shear force 40MPa at 300°C. Re-melting point of the composition is 409°C after TLPS when there is additional Cu supply from substrate and terminal of mounted die.
Soldier-worn augmented reality system for tactical icon visualization

This paper describes the development and demonstration of a soldier-worn augmented reality system testbed that provides intuitive „heads-up‟ visualization of tactically-relevant geo-registered icons. Our system combines a robust soldier pose estimation capability with a helmet mounted see-through display to accurately overlay geo-registered iconography (i.e., navigation waypoints, blue forces, aircraft) on the soldier‟s view of reality. Applied Research Associates (ARA), in partnership with BAE Systems and the University of North Carolina – Chapel Hill (UNC-CH), has developed this testbed system in Phase 2 of the DARPA ULTRA-Vis (Urban Leader Tactical, Response, Awareness, and Visualization) program. The ULTRA-Vis testbed system functions in unprepared outdoor environments and is robust to numerous magnetic disturbances. We achieve accurate and robust pose estimation through fusion of inertial, magnetic, GPS, and computer vision data acquired from helmet kit sensors. Icons are rendered on a high-brightness, 40°x30° field of view see-through display. The system incorporates an information management engine to convert CoT (Cursor-onTarget) external data feeds into mil-standard icons for visualization. The user interface provides intuitive information display to support soldier navigation and situational awareness of mission-critical tactical information.
Query based event extraction along a timeline

In this paper, we present a framework and a system that extracts events relevant to a query from a collection C of documents, and places such events along a timeline. Each event is represented by a sentence extracted from C, based on the assumption that "important" events are widely cited in many documents for a period of time within which these events are of interest. In our experiments, we used queries that are event types ("earthquake") and person names (e.g. "George Bush"). Evaluation was performed using G8 leader names as queries: comparison made by human evaluators between manually and system generated timelines showed that although manually generated timelines are on average more preferable, system generated timelines are sometimes judged to be better than manually constructed ones.
The Limits of Popularity-Based Recommendations, and the Role of Social Ties

In this paper we introduce a mathematical model that captures some of the salient features of recommender systems that are based on popularity and that try to exploit social ties among the users. We show that, under very general conditions, the market always converges to a steady state, for which we are able to give an explicit form. Thanks to this we can tell rather precisely how much a market is altered by a recommendation system, and determine the power of users to influence others. Our theoretical results are complemented by experiments with real world social networks showing that social graphs prevent large market distortions in spite of the presence of highly influential users.
