Automated Generation of Holographic Heart Visualization from Coronary Tomography for Multi-place Medical Diagnostics using Holographic devices

Medical imaging techniques play an important role in the diagnostic process. Through these techniques, it is possible to observe and analyze hidden details of the human anatomy, which is critical to the success of surgeries or clinical treatments. In so doing, an extensive experience in analyzing digital medical images is requested. However, physicians do not currently master such expertise. Therefore, greater accuracy and improved technology in dealing with these images must be sought. In particular, according to the Center for Disease Control and Prevention, about 610,000 people die of heart disease in the United States every year, which equates to 1 in every 4 deaths. Thus, computational tools for dealing with this grim reality are also imperative. In this context, emerging technologies such as Mixed Reality (MR) and Holography are increasing rapidly. These technologies allow for 1) the creation of high-definition virtual computing models of human organs and 2) the direct manipulation of interacting interfaces through such 3D models within a holographic environment that blends virtual and real elements seamlessly. This work combines several imaging techniques to support the automated generation of Holographic 3D volumetric heart models from coronary tomography. In turn, these models are presented in a real time shared holographic experience using Microsoft’s HoloLens, without the need of any further editing of the generated model. As a result, a tangible collaborative medical diagnostic solution, using shared reality concepts with other MR devices, such as HTC’s Vive, is provided.

NTimeUnit: Testing Software with Respect to Execution Time

Testing is an important part of the software development process. Many forms of testing are used, including unit testing, integration testing, and stress testing. Unit testing is particularly important in that it allows errors to be detected sooner, saving time and money. An often overlooked aspect of unit testing is expected performance . For example, binary search is an O(lgn) algorithm — what if a binary search method returns the correct result, but performs in O(n) time. Is it still correct? Most would argue it is not. We are developing an extension to NUnit called NTimeUnit that allows the tester to assert the expected performance of a method. The testing framework makes repeated calls to the method for a range of n, collects timing data, and attempts to identify the big-Oh category the method falls into. We have a preliminary implementation of NTimeUnit, and present our initial findings.
Genetics and population analysis Recombination-filtered genomic datasets by information

Summary: With the increasing amount of DNA sequence data available from natural populations, new computational methods are needed to efficiently process raw sequences into formats that are applicable to a variety of analytical methods. One highly successful approach to inferring aspects of demographic history is grounded in coalescent theory. Many of these methods restrict themselves to perfectly tree-like genealogies (i.e. regions with no observed recombination), because theoretical difficulties prevent ready statistical evaluation of recombining regions. However, determining which recombination-filtered dataset to analyze from a larger recombination-rich genomic region is a non-trivial problem. Current applications primarily aim to quantify recombination rates (rather than produce optimal recombination-filtered blocks), require significant manual intervention, and are impractical for multiple genomic datasets in high-throughput, automated research environments. Here, we present a fast, simple and automatable command-line program that extracts optimal recombination-filtered blocks (no four-gamete violations) from recombination-rich genomic re-sequence data.
Comparative histological and ultrastructural studies on the liver and pancreas of Schilbe mystus and Labeo niloticus

he present investigation aims to illustrate the histological and ultrastructural differences of the liver and pancreas of a carnivorous fish, Schilbe mystus, and a herbivorous fish, Labeo niloticus. The histological examination of the liver of both studied species revealed that the liver is mainly composed of a continuous compact field of the hepatocytes. The hepatocyte-sinusoidal structure of the liver of Schilbe mystus consists of the solid form and tubular one, while that of Labeo niloticus consists of the tubular form and cord-like one. The ultrastructural examination of the liver of both studied species revealed that it is composed mainly of hepatocytes, Kupffer (macrophages) and to (fat-storing) cells. The hepatocytes of Schilbe mystus are characterized by the presence of numerous glycogen rosettes, numerous lipid droplets and a rough endoplasmic reticulum, while those of Labeo niloticus are characterized by the presence of numerous glycogen rosettes, a few lipid droplets and a rough endoplasmic reticulum. The hepatocytes of both studied species possess numerous microvilli, which extend into the space of Disse or into the bile canaliculi lumina. In both studied species, there is a prominent perisinusoidal space between the hepatocytes and blood sinusoids, the space of Disse. This space usually contains the Ito cells, which are stellate in shape and are characterized by the presence of lipid droplets. The bile canaliculi of Schilbe mystus are of the intercellular type, while those of Labeo niloticus are of both the intercellular and intracellular types. The histological investigation of the pancreas of both studied species revealed that there are three types: the compact, disseminated and intrahepatic types. This pancreas showed that it consists of a highly lobulated gland of the compound acinar type. The acinar (pancreatic) cells are pyramidal in shape; they possess a basophilic cytoplasm and eosinophilic zymogenous secretory granules. The ultrastructural investigation of the acinar cells of both studied species revealed two cell types: the dark and light acinar cells. These cells are characterized by the presence of numerous zymogenous secretory granules and a well-developed rough endoplasmic reticulum.
Algorithms for Detecting Disputed Information: Final Version

FP7-ICT Collaborative Project ICT-2013-611233 P HEME Deliverable D4.2. 2 (WP4) This deliverable reports on building and evaluating resources for contradiction detection in the context of information veriﬁcation in user-generated content for the PHEME project. The resources include special-purpose Recognizing Textual Entailment (RTE) datasets and machine learning-based systems trained on these datasets. The systems are evaluated in terms of baseline strategies, utilizing existing RTE collections and systems, and compared with scores reported in the literature. The best scores on classifying contradictory text pairs achieve comparable F-scores across the datasets and the systems that we have investigated. We conclude that our results on contradiction detection in social media data are state-of-the-art.
DEMOGRAPHY OF THE ARABLE WEED DIPLOTAXIS ERUCOIDES IN CENTRAL CATALONIA, SPAIN

The demographic performance of a Mediterranean annual arable weed (Diplotaxis erucoides) related to both environmental conditions and disturbance was studied in an agricultural system disturbed by ploughing at various times in the year. Comparative analysis of survival curves reveals that mortality rates are dependent on a variety of environmental conditions, namely competition with neighbouring plants, frost, and availability of water resources. The demographic response of D. erucoides may vary depending upon how the unfavourableness of the environment compares with its physiological tolerance. Under environmental conditions not exceeding its physiological tolerance, D. erucoides reacts through phenotypic plasticity. However, in arable fields where periodic mechanical disturbance removed all individuals before reproduction, or unfavourable environmental conditions such as frost and drought exceeded the physiological tolerance of D. erucoides, widespread mortality occurred. Persistence then depended on hi.
ANTIOXIDANT EFFECT OF NYCTANTHES ARBOR TRISTIS L. ON D- GALACTOSAMINE INDUCED HEPATOTOXICITY IN RATS

To investigate the antioxidant activity of Nyctanthes arbor tristis. In albino wistar rats. Rats were divided into four groups, groups 1 received 0.9% saline; groups 2 received control and ethanolic extract of Nyctanthes arbor tristis (300mg/kg BW); groups 3 received Dgalactosamine (400mg/kg/BW) and group 4 received D-galactosamine and ethanolic extract of Nyctanthes arbor tristis for the total experimental period of 12 hrs. The results showed significantly elevated levels of serum AST (Aspartate aminotransferase), ALT (Alanine aminotransferase) and thiobarbituric acid reactive substances (TBARS), significantly lowered enzymic antioxidant activity of superoxide dismutase (SOD), catalase (CAT) and Glutathione peroxidase (Gpx) in D-galactosamine treated rats as compared to those of the experimental control rats. Ethanolic extract of Nyctanthes arbor tristis was administered at a dose of 300 mg/kg of body weight/day for the last 12hrs of the experiment to rats with D-galactosamine induced liver injury, which significantly decreased AST and ALT activities in serum, and also the hepatic level of TBARS, significantly elevated the activities of superoxide dismutase (SOD), catalase (CAT) and Glutathione peroxidase (GPx) in liver at the end of the experimental period as compared to those of untreated D Galactosamine - administered rats. Thus, our data indicate that treatment with H. indicus extract offers protection against free radical-mediated oxidative stress in serum and liver of animals with D-galactosamine induced liver injury.
Lysine and threonine responses in Ross TP16 male broilers

SUMMARY Today’s economy requires minimal feed cost for poultry producers to maintain a profit. Two experiments were performed to evaluate Lys (2 levels) and Thr (4 levels) factorial responses in Ross TP16 (Test Product 16) high-yielding male broilers from 14 to 28 d and 28 to 42 d of age. From 14 to 28 d (experiment 1), digestible Lys was fed at 1.12 and 1.18% of the diet. The basal diets contained digestible Thr at 0.69, 0.73, 0.77, and 0.81% of the diet, and l-Thr was added to achieve supplemented Thr diets. From 28 to 42 d (experiment 2), the basal test diet contained 1.00% digestible Lys and 0.60% digestible Thr. Additions of crystalline Lys and Thr yielded additional digestible levels of Lys (1.05% of diet) and Thr (0.64, 0.68, and 0.72% of diet). Live performance measurements in experiment 1 did not differ among treatments. In experiment 2, increasing Lys and Thr in the diet improved some live performance parameters, but 1.05% Lys may have been too high to estimate a Thr-to-Lys ratio, as indicated by significant BW gain and feed intake interactions. We conclude, based on the 28- to 42-d interactions, that a Thr-to-Lys ratio of 68 supports adequate growth in birds fed the 1.00% digestible Lys.
Avoidance of Suspended Sediment by Juvenile Coho Salmon

Abstract Some water quality standards established by the states permit only minor increases in suspended sediment when background turbidity is low, allow greater absolute increases as background levels rise, and do not consider acclimation of stream biota to high turbidity. Juvenile coho salmon (Oncorhynchus kisutch) were subjected to experimentally elevated concentrations of suspended sediment and did not avoid moderate turbidity increases when background levels were low, but exhibited significant avoidance when turbidity exceeded a threshold that was relatively high (>70 NTU) and was varied according to previous suspended sediment exposure.
Quantification of Morphological Variation within Species of Anoura from Ecuador, with an Emphasis on A. fistulata (Chiroptera: Phyllostomidae)

The original description for Anoura fistulata (long-lipped bat) was mostly qualitative in nature. Here we make a quantitative reassessment of morphological variation in skull shape for this and other Ecuadorian species. Our goal is to provide a perspective into morphospace for understanding the boundaries and extent of variation within and among species of Anoura occurring in Ecuador. Our results show that, besides its singular differences in soft-tissue anatomy, the distribution of samples in morphospace for A. fistulata suggests this species occupies an intermediate space between A. geoffroyi and A. caudifer. Anoura geoffroyi and A. caudifer share opposite regions of morphospace, where size is the largest factor contributing to variation, and along the shape vector both species are distinguished mostly by a contraction of the maxilla and a contraction of the braincase, respectively. Although size is the main factor determining boundaries among species, for A. cultrata shape seems to be more relevant, as its geometric configuration of the skull is remarkably different. The other species are similar in shape when size is factored out. An unusual group of specimens may require further study as they may represent an unknown species, as these occupy unexpected areas of morphospace. A discussion of why we do not think there is evidence to assign this unusual group to any of the small species of Anoura (i.e. A. caudifer, A. aequatoris, and A. luismanueli) is also included. Populations of A. geoffroyi from the western and eastern slopes of the Andes show statistically supported differences in most of the measured morphological traits, however this is not true for A. caudifer. The effect of western and eastern habitats on the geometric configuration of the skull is different and inverted between both species. This results in a statistical interaction between the two slopes of the Andes and the two species. Eastern populations of A. geoffroyi and A. caudifer are morphologically closer than western populations in both species. Anoura geoffroyi possesses a larger altitudinal range and a larger body size, a positive correlation that may concur with the hypothesis of body size serving as a buffer to extreme or highly variable environments. The frequency distribution of character states in morphospace and their differentiation across the various species of Anoura is discussed in the context of diet and habitat.
Domain-Specific Reduction of Language Model Databases: Overcoming Chatbot Implementation Obstacles

This paper addresses optimization of language model databases for use in range of chatbots, e.g . virtual conversational mentors. The proliferation and practical use of chatbots depends on the ability of users to conversationally retrieve information or activate events. These conversations ideally help the user efficiently access a broad set of computational functions accurately and in as few turns as possible. However, there is a concomitant pressure to reduce size, increase speed, and enable offline capabilities. Such offline and online dialog capabilities are particularly vital for DoD applications, which are increasingly being developed to produce intelligent agents that help explain complex data and operate in low-resource environments ( e.g ., no reliable internet). Unfortunately, not only is natural language processing a computationally expensive task, but language models are often heavyweight, with large storage space footprints and challenges for keeping data in-memory that affect search and retrieval times. A chatbot must be able to understand and respond to a variety of unique user inputs and do so within the limits of conversationally tolerable latencies. The difficulty comes in trying to balance an effective chat agent while optimizing storage for peak performance. This paper applies and analyzes two methods for reducing language models, using the Google News Word2vec model as an example. These methods were implemented with the goal to support natural a language dialog system without the storage overhead of the significantly larger comprehensive models. Two metrics were applied to reduce the language model: word frequency and relevance to the domain-specific information that the agent can discuss. We will document and analyze similar efforts, set forth potential approaches, discuss solutions within our environment, quantify impacts of the implementation of these approaches, outline future applications, and suggest topics for further research. The paper closes with ways in which others can adopt this approach to their own efforts.
Factors Associated with Elevated Depression in Family Caregivers of End Stage Kidney Disease in Nairobi County, Kenya

Following a diagnosis of kidney failure, known as End Stage Kidney Disease (ESKD), the patient is normally required to undergo dialysis to sustain life. For most patients, the family is the most affected as it has to cope with changes in medication, diet and dialysis. Usually, one or two members of the family become primarily responsible for taking care of the patient and are referred to as the family caregivers (FCGs). Studies have shown that this population has an onerous caregiving burden with the patient requiring much care due to the unique demands of ESKD which may lead to psychological difficulties, including depression. However, little research has been done regarding the development of depression in this population, yet ESKD is considered a family matter. There is therefore, the need to consider the incidence of and factors associated with depression among FCGs of patients with ESKD. In a crosssectional study, using a convenience sample of 96 FCGs and their patients in various hospitals in Nairobi and the Beck’s Depression Inventory (BDI) tool, this study found that 33.3% of the sample, with a mean depression score of 18.9 (+ 6.5 SD) had mild depression. There was no significant association between most socio-demographic and socio-behavioural characteristics of the patients and FCGs and FCG depression that were measured. These variables included substance abuse, age, duration of care for patient and educational level of FCGs and patients. However, gender was found to be significantly associated with depression among the FCGs. Additionally, those not residing with the patients had a significantly high level of depression than those residing with the patients. These findings are significant for clinical practice for the multi-disciplinary team involved in ESKD that includes the medical and psychological practitioners.
STRUGGLE FOR SPACE IN COASTAL CITIES: A CELLULAR AUTOMATA MODEL FOR SIMULATING URBAN STRATIFICATION DYNAMICS

The social production of Brazilian cities has historically accentuated the diï¬€erences between urban locations and promoted urban stratification. This reality is particularly pronounced in coastal areas, where the locational advantages of areas near the sea create an increasingly competitive and exclusionary land market. Through methods of computational modeling and simulation, this work analyzes the production of the urban space of Caraguatatuba, a Brazilian city located on the northern coast of São Paulo State. We developed a cellular automata model called URBIS-Caragua to explore the dynamics of urban stratification bounded by urban legislation and the spatial distribution of residential location opportunities. In this process, particular attention was directed towards the empirical parameterization of the model, which relied on exploratory data analysis and statistical models for the periods 1991-2000 and 2000-2010. Through the parameterization and development of simulation experiments about past dynamics, it was possible to obtain new insights about how trends of urban expansion and stratification changed over the recent years, and the possible relation of these trends to urban legislation, locational factors and sociodemographic pressures. The experiments about future dynamics (2010-2025) indicated that the Master Plan of the city, approved in 2011, is likely to reinforce trends that have historically established an unequal distribution of opportunities for residents that belong to diï¬€erent social groups.
Viral and Host Factors Associated with HIV-1 Vertical Transmission and Pathogenesis

The majority of neonates and infants acquire HIV-1 infection through vertical transmission. In addition these HIV-1 infected infants have a higher viral load and progress to AIDS faster than adults, often times more rapidly than their own infected mothers. However, the mechanisms of this differential disease progression are not well understood. Several studies have shown, including work from our laboratory, that it is the transmission of the minor genotype with the R5 phenotype that is involved in transmission. We have also shown that a lower viral heterogeneity may influence vertical transmission. Moreover, we have also shown that there is a differential HIV-1 replication and HIV-1 gene expression in neonatal cells as compared to adult cells. The hypothesis of this dissertation is that viral determinants and cellular factors in neonatal and adult mononuclear cells influence HIV-1 replication and HIV-1 gene expression. In this dissertation I have molecularly characterized the HIV-1 long terminal repeat (LTR) from 6 mother-infant HIV-1 infected pairs, and shown that mutations generated during vertical transmission correlate with HIV-1 gene expression. Furthermore, I have also shown that there was a low degree of viral heterogeneity and a high conservation of critical transcription factor binding sites within the LTR. I have also shown that nuclear extracts from neonatal (cord) mononuclear cells bind with higher efficiencies to HIV-1 LTR as compared to nuclear extracts from adult mononuclear cells. In addition, I have also made strides in trying to elucidate the mechanisms of differential HIV-1 replication and gene expression. I have shown that there is a differential HIV-1 replication in naive and memory T-lymphocytes from cord vs. adults and this increased HIV-1 replication was
Charge Monitors at the Relativistic Electron Gun for Atomic Exploration – REGAE

Relativistic electron diffraction requires electron bunches of extreme quality. Typical values are: electron bunch charges of 100 fC, pulse duration of 10 fs, emittance of 5 nm. In order to operate an accelerator in such conditions proper diagnostics is needed. Furthermore any possible shot-to-shot variation has to be monitored especially when it comes to the analysis of the diffraction pattern. Desired properties of electron bunches to be diagnosed include: position, charge, emittance, bunch length, energy and energy spread. In this paper the beam charge as well as dark current monitors implemented at REGAE are described with a main focus on Faraday cups.
