Involvement of the central nervous system in adult patients with acute myeloid leukemia

Involvement of the central nervous system (CNS) arising in patients with acute myeloid leukaemia (AML) are rare at the time of diagnosis, but more often occur during relapse or after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Clinical manifestations include symptoms of increased intracranial pressure, cranial nerve palsies and altered mental status. Furthermore,
Bering Sea surface water conditions during Marine Isotope Stages 12 to 10 at Navarin Canyon (IODP Site U1345)

Abstract. Records of past warm periods are essential for understanding interglacial climate system dynamics. Marine Isotope Stage 11 occurred from 425 to 394 ka, when global ice volume was the lowest, sea level was the highest, and terrestrial temperatures were the warmest of the last 500 kyr. Because of its extreme character, this interval has been considered an analog for the next century of climate change. The Bering Sea is ideally situated to record how opening or closing of the Pacific–Arctic Ocean gateway (Bering Strait) impacted primary productivity, sea ice, and sediment transport in the past; however, little is known about this region prior to 125 ka. IODP Expedition 323 to the Bering Sea offered the unparalleled opportunity to look in detail at time periods older than had been previously retrieved using gravity and piston cores. Here we present a multi-proxy record for Marine Isotope Stages 12 to 10 from Site U1345, located near the continental shelf-slope break. MIS 11 is bracketed by highly productive laminated intervals that may have been triggered by flooding of the Beringian shelf. Although sea ice is reduced during the early MIS 11 laminations, it remains present at the site throughout both glacials and MIS 11. High summer insolation is associated with higher productivity but colder sea surface temperatures, which implies that productivity was likely driven by increased upwelling. Multiple examples of Pacific–Atlantic teleconnections are presented including laminations deposited at the end of MIS 11 in synchrony with millennial-scale expansions in sea ice in the Bering Sea and stadial events seen in the North Atlantic. When global eustatic sea level was at its peak, a series of anomalous conditions are seen at U1345. We examine whether this is evidence for a reversal of Bering Strait throughflow, an advance of Beringian tidewater glaciers, or a turbidite.
SORPTION OF S-TRIAZINES IN BRAZILIAN RAINFOREST SOILS

This research was conducted to evaluate the sorption of Ametryn, Atrazine, Simazine, Prometrine and Metamitron to soils from �Mata Atlântica� at Ubatuba region (Atlantic rainforest soils), employing the batch equilibrium approach. The herbicides were weakly retained in soils with low soil organic matter (SOM) content and thus presenting high potential to water contamination. All herbicides have shown high Koc at Typic Humaquepts soil, the higher in SOM content. The sorption isotherms for the herbicides at Typic Humaquepts soil suggested specific interactions between herbicides and SOM probably with partial protonation of herbicides followed by ion-exchange processes and/or hydrogen bonding formation of hydroxyl groups on the SOM surface
Population subdivision of saddled seabream Oblada melanura in the Aegean Sea revealed by genetic and morphometric analyses

The population structure of marine fishes is often cryptic, due to limited knowledge about life history and ecological habitats. Understanding environmental stability is a challenge to retrieve possible structuring patterns responsible for dispersal and demographic habits. In the present study, a combination of genetic and phenotypic assessments was applied in order to inves- tigate population structure of the saddled seabream Oblada melanura in the Aegean Sea, eastern Mediterranean basin. Analyses of 6 microsatellite loci and 15 morphometric characters revealed that saddled seabream individuals differ among northern, southern and central Aegean popula- tions. These observed boundaries may be related to the differentiated seascape of the Aegean Sea, suggesting that oceanographic factors are a significant stressor for population subdivision of the saddled seabream. Individual-based landscape genetic approaches and multivariate analysis of the morphometric characters suggest the presence of habitat-related limitations of saddled seabream dispersal potential. Molecular genetics and phenotypic analyses along with life-history traits provide useful informative data for the management and conservation schemes applied for this species in the Aegean Sea.
Heart Rate Variability analysis as a tool for assessing the effects of chi meditation on cardiovascular regulation.

Alrededor de 30 indices han sido propuestos para evaluar la Variabilidad de la Frecuencia Cardiaca. Algunos de esos indices son matematicamente identicos o muy semejantes a otros y los resultados pueden ser interpretados desde puntos de vista completamente distintos. Al comparar varios indices estimados a partir de un tacograma y combinando la significacion estadistica con la plausibilidad biologica pudiera mejorarse la interpretacion de los resultados. Utilizando el paquete de analisis “KubiosHRV” estudiamos la base de datos de senales R-R “Chi meditation”, disponible en el portal “Physionet.org”, centrandonos en las interrogantes siguientes: i) ? cuales indices son los mas adecuados para describir los efectos de la meditacion? ii) ? son los efectos de la meditacion beneficiosos, nocivos o insustanciales? iii) ? cuales son los eventos fisiologicos asociados a la meditacion? Se concluye que el componente de baja frecuencia del espectro de potencia (LF), la relacion LF/HF y los indices no lineales α 1 yα 2, la razon de recurrencia y la entropia de Shannon, fueron los indicadores mas apropiados (p < 0.05). Los cambios observados parecen armonizar con cambios observados en otras acciones promotoras de salud como entrenamiento fisico, combatir el estres, mientras que exhiben una tendencia opuesta a los cambios asociados al envejecimiento, habito de fumar, elevados niveles de glucosa, denervacion cardiaca, e insuficiencia cardiaca congestiva. Los cambios inducidos por la meditacion chi parecen estar asociados a incrementos en el componente respiratorio proximo a los 0.04 hertzios, a una menor entropia y una menor correlacion a largo termino combinadas a una mayor complejidad cardiovascular. Palabras Clave. Variabilidad de la Frecuencia Cardiaca, complejidad cardiovascular, meditacion chi, modulacion del ritmo cardiaco por la respiracion.
Development of High-Performance UV Detector Using Nanocrystalline Diamond Thin Film

Nanocrystalline diamond (NCD) films are promising materials for wide-spread applications due to their outstanding characteristics of chemical, physical, and highly smooth surface. Our present work aimed at the fabrication of high performance diamond-based UV detector. NCD films were prepared by microwave plasma enhanced chemical vapor deposition process, and then Au interdigital electrodes were deposited onto the surface of the as-grown NCD film by sputtering technique. Annealing procedures were conducted at various temperatures to obtain Ohmic contact of NCD/Au structure. The surface morphology, microstructure, and wettablity of the NCD films were analyzed by scanning electron microscopy, atomic forced microscopy, Raman spectroscopy, X-ray photoelectron spectroscopy, transmission electron microscopy, and water contact angle measurement, respectively. The electrical property and photoconductivity of the fabricated devices were tested for UV detection application. It was found that the NCD films possessed high sp3 fraction of 68.6%, low surface roughness of 9.6 nm, and good hydrophobicity, as deposited under working pressure of 40 Torr. Also, the NCD/Au structure annealed at 500°C exhibited a good Ohmic contact characteristic, high detection efficiency, and fast response to UV irradiation in air ambient. The proposed study indeed demonstrates prospective applications of NCD films in UV detector, photocatalyst, solar cell, and so on.
Computational Techniques for Haplotype Inference and for Local Alignment Significance

This thesis which consists of an introduction and four peer–reviewed original publications studies the problems of haplotype inference (haplotyping) and local alignment significance. The problems studied here belong to the broad area of bioinformatics and computational biology. The presented solutions are computationally fast and accurate, which makes them practical in high–throughput sequence data analysis. Haplotype inference is a computational problem where the goal is to estimate haplotypes from a sample of genotypes as accurately as possible. This problem is important as the direct measurement of haplotypes is difficult, whereas the genotypes are easier to quantify. Haplotypes are the key–players when studying for example the genetic causes of diseases. In this thesis, three methods are presented for the haplotype inference problem referred to as HaploParser, HIT, and BACH. HaploParser is based on a combinatorial mosaic model and hierarchical parsing that together mimic recombinations and point–mutations in a biologically plausible way. In this mosaic model, the current population is assumed to be evolved from a small founder population. Thus, the haplotypes of the current population are recombinations of the (implicit) founder haplotypes with some point–mutations.
Parasitic Infections of Cattle in North Eastern Region of IndiaÃ¢ÂÂAn Overview

The Northeast (NE) India is the eastern most region of India, constitutes about 8% of India’s size and its population is approximately 3.1% of the total Indian population. The NE region of India though predominantly dependent on cultivation of crops, animal husbandry is an inseparable part of the economy. They not only contribute to their income but also their best insurance against any natural calamity. The humid climatic conditions of this region are very conducive for the rapid growth and multiplication of parasites. They cause clinical and subclinical parasitism. Subclinical infections are responsible for high morbidity and mortality in young animals and enormous production losses in adults. Different species of gastrointestinal parasites i.e. Haemonchus, Strongyloides, Mecistocirrus, Cooperia, Neoascaris, Fasciola gigantica, Paramphistomes, Bunostomum phlebotomum, Nematodirus fillicolis, Nematodirus helvetianus, Trichostrongylus sp. , Oesophagostomum raditum, Moniezia sp. , Trichuris sp. , Eimeria bovis, E. zuernii, E. subspherica, E. bukidnonensis, E. auburnensis, E. ellipsoidalis, E. alabamensis etc were reported from cattle of this region. Zoonotic parasites such as Cryptosporidium parvum, Giardia duodenalis, Cysticercus bovis, Fasciola hepatica and hydatidosis in cattle was also reported. Cattle ticks and tick borne diseases (TBD) such as Babesiosis, Oriental theileriosis and Anaplasmosis are also observed in this region. Many epidemiological factors are responsible for causing parasitic infections in cattle of this region. So, proper monitoring, diagnosis and control of parasitic infections in cattle of this region is required for sustainable growth and development of cattle population.

Paper— An Exploration of Factors Influencing Self-Efficacy in Online Learning : A Systematic Review An Exploration of Factors Influencing Self-Efficacy in Online Learning : A Systematic Review

— This review examines 12 years of research by focusing on the following question: What are the factors that influence self-efficacy in an online learning environment? There has been a plethora of research concerning self-efficacy. However, few works have focused on the sources of self-efficacy in online-learning environments. Systematic searches of numerous online databases published between 2005 and 2017, which covered factors influencing self-efficacy in online learning context, resulted in the investigation of 25 studies. The data were extracted, organized and analyzed using a narrative synthesis. Results revealed that various factors improved self-efficacy and provided evidence of significant sources of self-efficacy in the context of online learning. Moreover, the investigation provides guidance for further research in designing online learning environments to enhance the self-efficacy of learners.
Defensive behaviour in pit vipers of the genus Bothrops (Serpentes, Viperidae)

The genus Bothrops encompasses at least six evolutionary lineages that show a great diversification in macro and microhabitat use. We studied the defensive behaviour of one species of each of five lineages within the genus Bothrops: B. alternatus, B. jararaca, B. jararacussu, B. moojeni and B. pauloensis. Specifically, we investigated if this diversification in habitat use was accompanied by a similar divergence in the characters related to defensive behaviour in the genus. Eight behavioural categories were recorded, five of which may be classified as “threatening” (strike, tail vibration, head and neck elevation, dorsoventral body compression and body thrashing); two as “escape” (locomotor escape and cocking); and one as “cryptic” (head hiding). We observed significant differences in four behavioural categories. We also detected a significant difference in the way species elevated their head and neck. Tail vibration and strikes were the most common behaviours presented, and snakes that displayed their tails struck more frequently than those that did not display. A reconstruction of characters related to defensive behaviour on a phylogeny of Bothrops indicated an increase in the use of dorsoventral body compression in the groups alternatus and neuwiedi, which may be associated with the invasion of open areas by these lineages.
The relative importance of chlorine and bromine radicals in the oxidation of atmospheric mercury at Barrow, Alaska

[1] Mercury is a toxic environmental contaminant originating from both natural and anthropogenic sources. Gaseous elemental mercury (GEM) is relatively long lived in the midlatitudes and can be transported long distances in the atmosphere. In the Polar Regions, mercury can have a much shorter lifetime and is known to experience episodic depletions following polar sunrise in concert with ozone depletion events. A series of photochemically initiated reactions involving halogen radicals is believed to be the primary pathway responsible for converting elemental mercury to oxidized forms of reactive gaseous mercury (RGM) that are subsequently deposited to snow and ice surfaces. Using field measurements from the Ocean-Atmosphere-Sea Ice-Snowpack (OASIS) 2009 field campaign of GEM, RGM, ozone, and a large suite of both inorganic halogen and volatile organic compounds, we calculated steady state Br and Cl atom concentrations and investigated the contribution of Br, BrO, Cl, ClO, O3, and OH to the observed decay of GEM for five cases of apparent first-order decay. The results of this study indicate that Br and BrO are the dominant oxidizers for Arctic mercury depletion events, with Br having the greatest overall contribution to GEM decay. Ozone is likely the primary factor controlling the relative contribution of Br and BrO, as BrO is a product of the reaction of Br with ozone, and reaction with O3 can be the largest Br atom sink. Cl was not found to be significant in any of the studied events; however, this result is highly dependent on the rate constant, for which there is a large range in the literature. Modeled 48 h back trajectories of the mercury depletion events studied here indicate significant time spent over sea ice–covered regions, where the concentration of halogen radicals is likely higher than those estimated using local-scale chemical mole fractions.
Nonequilibrium quantum systems: Divergence between global and local descriptions

Even photosynthesis—the most basic natural phenomenon underlying life on Earth—involves the nontrivial processing of excitations at the pico- and femtosecond scales during light-harvesting. The desire to understand such natural phenomena, as well as interpret the output from ultrafast experimental probes, creates an urgent need for accurate quantitative theories of open quantum systems. However it is unclear how best to generalize the well-established assumptions of an isolated system, particularly under nonequilibrium conditions. Here we compare two popular approaches: a description in terms of a direct product of the states of each individual system (i.e., a local approach) versus the use of new states resulting from diagonalizing the whole Hamiltonian (i.e., a global approach). The main difference lies in finding suitable operators to derive the Lindbladian and hence the master equation. We show that their equivalence fails when the system is open, in particular under the experimentally ubiquitous condition of a temperature gradient. By solving for the steady state populations and calculating the heat flux as a test observable, we uncover stark differences between the formulations. This divergence highlights the need to establish rigorous ranges of applicability for such methods in modeling nanoscale transfer phenomena—including during the light-harvesting process in photosynthesis.
INEFFICIENT DRIVING OF BULK TURBULENCE BY ACTIVE GALACTIC NUCLEI IN A HYDRODYNAMIC MODEL OF THE INTRACLUSTER MEDIUM

Central jetted active galactic nuclei (AGNs) appear to heat the core regions of the intracluster medium (ICM) in cooling-core galaxy clusters and groups, thereby preventing a cooling catastrophe. However, the physical mechanism(s) by which the directed flow of kinetic energy is thermalized throughout the ICM core remains unclear. We examine one widely discussed mechanism whereby the AGN induces subsonic turbulence in the ambient medium, the dissipation of which provides the ICM heat source. Through controlled inviscid three-dimensional hydrodynamic simulations, we verify that explosive AGN-like events can launch gravity waves (g-modes) into the ambient ICM, which in turn decays to volume-filling turbulence. In our model, however, this process is found to be inefficient, with less than 1% of the energy injected by the AGN activity actually ending up in the turbulence of the ambient ICM. This efficiency is an order of magnitude or more too small to explain the observations of AGN-feedback in galaxy clusters and groups with short central cooling times. Atmospheres in which the g-modes are strongly trapped/confined have an even lower efficiency since, in these models, the excitation of turbulence relies on the g-modes’ ability to escape from the center of the cluster into the bulk ICM. Our results suggest that, if AGN-induced turbulence is indeed the mechanism by which the AGN heats the ICM core, its driving may rely on physics beyond that captured in our ideal hydrodynamic model.
Regional melt-pond fraction and albedo of thin Arctic first-year drift ice in late summer

Abstract. The paper presents a case study of the regional (≈150 km) morphological and optical properties of a relatively thin, 70–90 cm modal thickness, first-year Arctic sea ice pack in an advanced stage of melt. The study combines in situ broadband albedo measurements representative of the four main surface types (bare ice, dark melt ponds, bright melt ponds and open water) and images acquired by a helicopter-borne camera system during ice-survey flights. The data were collected during the 8-day ICE12 drift experiment carried out by the Norwegian Polar Institute in the Arctic, north of Svalbard at 82.3° N, from 26 July to 3 August 2012. A set of > 10 000 classified images covering about 28 km2 revealed a homogeneous melt across the study area with melt-pond coverage of ≈ 0.29 and open-water fraction of ≈ 0.11. A decrease in pond fractions observed in the 30 km marginal ice zone (MIZ) occurred in parallel with an increase in open-water coverage. The moving block bootstrap technique applied to sequences of classified sea-ice images and albedo of the four surface types yielded a regional albedo estimate of 0.37 (0.35; 0.40) and regional sea-ice albedo of 0.44 (0.42; 0.46). Random sampling from the set of classified images allowed assessment of the aggregate scale of at least 0.7 km2 for the study area. For the current setup configuration it implies a minimum set of 300 images to process in order to gain adequate statistics on the state of the ice cover. Variance analysis also emphasized the importance of longer series of in situ albedo measurements conducted for each surface type when performing regional upscaling. The uncertainty in the mean estimates of surface type albedo from in situ measurements contributed up to 95% of the variance of the estimated regional albedo, with the remaining variance resulting from the spatial inhomogeneity of sea-ice cover.
More Than Just Words: Modeling Non-Textual Characteristics of Podcasts

Recent years have witnessed the flourishing of podcasts, a unique type of audio medium. Prior work on podcast content modeling focused on analyzing Automatic Speech Recognition outputs, which ignored vocal, musical, and conversational properties (e.g., energy, humor, and creativity) that uniquely characterize this medium. In this paper, we present an Adversarial Learning-based Podcast Representation (ALPR) that captures non-textual aspects of podcasts. Through extensive experiments on a large-scale podcast dataset (88,728 episodes from 18,433 channels), we show that (1) ALPR significantly outperforms the state-of-the-art features developed for music and speech in predicting theseriousness andenergy of podcasts, and (2) incorporating ALPR significantly improves the performance of topic-based podcast-popularity prediction. Our experiments also reveal factors that correlate with podcast popularity.
