Actividad funcional cerebral en estado de reposo: REDES EN CONEXIÓN

El analisis de la conectividad funcional mediante resonancia magnetica funcional (RMf) puede llevarse a cabo durante la realizacion de una tarea, la percepcion de un estimulo o en estado de reposo. En tales casos, el estudio de la senal de baja frecuencia en la actividad cerebral a traves del contraste BOLD en estado de reposo ha revelado patrones de actividad cortical sincronizados, lo que ha permitido describir la arquitectura funcional intrinseca del cerebro humano. La comunidad cientifica internacional dispone de recursos compartidos que contribuiran mediante este analisis de RMf en estado de reposo a la obtencion de diagnosticos y tratamientos mas precisos y avanzados en el campo de las neurociencias. Recientemente, el Spanish Resting State Network (SRSN) se ha aunado a este proyecto colaborativo creando una estructura de habla espanola para la cooperacion entre los distintos grupos de investigacion en neurociencias (http://www.nitrc.org/projects/srsn).
Prognostic model for cervical cancer With disease : 104 Local recurrence : 63 Distant recurrence : 41 Regional recurrence : 36 Disease-free patients : 193 Alive : 22 Death : 82 Alive : 182 Death

Objective: To externally validate the prognostic models for predicting the time-dependent outcome in patients with locally advanced cervical cancer (LACC) who were treated with concurrent chemoradiotherapy in an independient cohort. Methods: A historical cohort of 297 women with LACC who were treated with radical concurrent chemoradiotherapy from 1999 to 2014 at the 12 de Octubre University Hospital (H12O), Madrid, Spain. The external validity of prognostic models was quantified regarding discrimination, calibration, measures of overall performance, and decision curve analyses. Results: The review identified 8 studies containing 13 prognostic models. Different (International Federation of Gynecology and Obstetrics [FIGO] stages, parametrium involvement, hydronephrosis, location of positive nodes, and race) but related cohorts with validation cohort (5-year overall survival [OS]=70%; 5-year disease-free survival [DFS]=64%; average age of 50; and over 79% squamous cell) were evaluated. The following models exhibited good external validity in terms of discrimination and calibration but limited clinical utility: the OS model at 3 year from Kidd et al.'s study (area under the receiver operating characteristic curve [AUROC]=0.69; threshold of clinical utility [TCU] between 36% and 50%), the models of DFS at 1 year from Kidd et al.'s study (AUROC=0.64; TCU between 24% and 32%) and 2 years from Rose et al.'s study (AUROC=0.70; TCU between 19% and 58%) and the distant recurrence model at 5 years from Kang et al.'s study (AUROC=0.67; TCU between 12% and 36%). Conclusion: The external validation revealed the statistical and clinical usefulness of 4 prognostic models published in the literature.
Effect of A-/ B-site Doping on Oxygen Non-Stoichiometry , Structure characteristics , and O 2 Releasing Behavior of La 1 − x Ca x Co 1 − y Fe y O 3 − δ Perovskites

Oxy-fuel combustion is one of the proposed technologies with the potential to achieve zero CO2 emission. La1−xCaxCo1−yFeyO3−δ (LCCF) perovskites are promising materials with high selectively for oxygen. In this study, the oxygen non-stoichiometry of perovskites LCCF was investigated by means of iodometric titration. LCCF was prepared using the liquid citrate method, and the phase structures were identified by X-ray diffraction. Fixed-bed experiments were performed to study the oxygen desorption performance of LCCF. The oxygen deficiency of LCCF increased with increasing Ca molar content of A site, but the value of δ of LCCF with increasing Fe molar content in B site is nearly constant. Experimental observation demonstrated that the O2 release amount of LCCF does not depend on oxygen non-stoichiometry δ generated from A-site doping. At the same time, doping Fe in B site has an obvious impact on the oxygen desorption amount.
ANewControl Framework forFlapping-WingVehicles based on 3DPendulumDynamics

In this paper, a new control framework for an insect-scale flapping-wing vehicle is presented that exploits passive aerodynamic effects to stabilize the attitude dynamics. Many flapping-wing robotic flyers and flying insects share a common morphological feature in that the center of mass (CoM) is below the center of pressure (CoP), which makes the hovering configuration intrinsically unstable with open-loop control. Motivated by the fact that the CoM should be ahead of the CoP to ensure the longitudinal stability of the flight dynamics, a new coordinate system is proposed by placing a virtual control point (VCP) above the CoP. The dynamics in the new coordinates are derived using a near-identity diffeomorphism which admits a partial feedback linearization with stable zero dynamics. The behavior of the zero dynamics resembles the dynamics of a 3D pendulum with an aerodynamic damper. An adaptive controller is proposed to make the upright orientation almost globally asymptotically stable over a bounded uncertainty of the aerodynamic drag coefficient. The controller is evaluated in simulation with a Harvard RoboBee following a virtual control point reference trajectory.
Deep Reinforcement Learning for 2048

In this paper, we explore the performance of a Reinforcement Learning algorithm using a Policy Neural Network to play the popular game 2048. After proposing a modelization of the state and action spaces, we review our learning process, and train a first model without incorporating any prior knowledge of the game. We prove that a simple Probabilistic Policy Network achieves a 4 times higher maximum score than the initial random policy. We then try to improve the learning process with Approximate Dynamic Programming. Finally we test the performances of our network by coupling it with Monte-Carlo Tree Search in order to encourage optimal decisions using an explorative methodology.

AN EFFICIENT STRUCTURE AWARE HALFTONING USING BIT-CLIMBER

In this paper, we present an efficient halftoning method in generating structurally similar halftone images. The proposed method uses bit-climbing algorithm where each pixel is flipped within inter-correlated blocks of a halftone image. Simulation results show that the proposed method reaches a better image quality with fewer evaluations than the conventional structure aware halftone methods which uses pixel swapping.

Survey of Malware Distribution Networks

A vast spectrum of people are interacting with Internet, either to perform their daily activities online such as banking, or to simply surf the web. As more people are connected not only they become more dependent on it, yet their systems can be the target of adversaries with different aims. Recently, one of the attacks that has become very common in the network society, is the distribution of malware by malware distribution networks or MDNs. The main components in a malware distribution network, are the landing pages and malware repository. The goal of the MDNs is to redirect the user to the malware repository through the landing pages where a malicious binary is downloaded by the user and thus, the adversary can extend his attack. In this paper, a complete overview of the malware distribution network is provided, explaining many different aspects regarding the malware distribution network.

Feeding and migration habits of white shark Carcharodon carcharias ( Lamniformes : Lamnidae ) from Isla Guadalupe inferred by analysis of stable isotopes δ 15 N and δ 13 C

Stable isotope composition of marine top predator’s tissues provides insight information of its trophic ecology and migratory behavior. Previous reports have shown that dermal tissues could record longer patterns of hunting and movement. Based on this, the aim of this study was to describe the feeding and migratory habits of the white shark from Isla Guadalupe, using stable isotopic analysis of dermis. We considered a small subset of many possible prey taxa that the sharks could have eaten throughout their migration: pinnipeds, squid and tuna. We grouped the data in five focal areas: Gulf of California, Coast of California, Isla Guadalupe, SOFA and Hawaii. We performed a Bayesian mixing model to study the trophic ecology of this top predator. Average isotopic values for dermis tissue of white shark were δ 13 C (-14.5‰) and δ 15 N (19.1‰). Corrected white shark dermal mean values to resemble muscle were δ13C (-16.6‰) and δ 15 N (21.2‰). Mixing model data from dermis showed predation in offshore areas such the SOFA and a main importance of pinnipeds as prey of the white shark in Isla Guadalupe. Rev. Biol. Trop. 62 (2): 637-647.

Title World Federation of Pediatric Imaging ( WFPI ) volunteer outreach through tele-reading : The pilot project in South Africa Permalink

Background Shortages in radiology services are estimated to affect 3.5–4.7 billion people worldwide. Teleradiology is a potential means of alleviating this shortage. Objective This paper examines the practicality and sustainability of a pilot pediatric teleradiology project at the Khayelitsha District Hospital in sub-Saharan Africa. We analyze how this World Federation of Pediatric Imaging (WFPI) program fares against the global challenges described in the current literature facing these practice types. Materials and methods A teleradiology pilot was developed to provide coverage to the Khayelitsha District Hospital after the district pediatrician requested assistance in interpreting radiographs. This program utilized a network of WFPI volunteer pediatric radiologists, direct JPEG conversion of digital radiographic images, and an e-mail delivery system of images, referral requests and teleradiology opinion. Data were collected retrospectively from referral cards and JPEG images of radiographs, as well as from the volunteer officer database. Results A total of 555 referral cards and 1,106 radiographs were submitted for teleradiology opinion during the course of this pilot program; 74.6% of requests for image interpretation were chest radiographs and 14.2% of those were for the evaluation of tuberculosis. There were 40 volunteer teleradiologists from 17 countries; all spoke English, and 14 were bilingual (8 fluent in Spanish, 5 in Portuguese, and 1 in Italian). Conclusion Teleradiology is a viable option to alleviate radiologist shortages in underserved areas, but there are many challenges to designing an adequate teleradiology system. The WFPI pilot teleradiology program can be considered a successful one.
Abiotic and biotic sources influencing spring new particle formation in North East Greenland

In order to improve our ability to predict cloud properties, radiative balance and climate, it is crucial to understand the mechanisms that trigger the formation of new particles and their growth to activation sizes. Using an array of real time aerosol measurements, we report a categorization of the aerosol population taken at Villum Research Station, Station Nord (VRS) in North Greenland during a period of 88 days (February–May 2015). A number of New Particle Formation (NPF) events were detected and are herein discussed. Air mass back trajectories analysis plotted over snow-sea ice satellite maps allowed us to correlate early spring (April) NPF events with air masses travelling mainly over snow on land and sea ice, whereas late spring (May) NPF events were associated with air masses that have passed mainly over sea ice regions. Concomitant aerosol mass spectrometry analysis suggests methanesulfonic acid (MSA) and molecular iodine (I2) may be involved in the NPF mechanisms. The source of MSA was attributed to open leads within the sea ice. By contrast, iodine was associated with air masses over snow on land and over sea ice, suggesting both abiotic and biotic sources. Measurements of nucleating particle composition as well as gas-phase species are needed to improve our understanding of the links between emissions, aerosols, cloud and climate in the Arctic; therefore our ability to model such processes.
Options for the abatement of methane and nitrous oxide from ruminant production – a review

Agriculture produces an estimated 10%-12% of total global anthropogenic greenhouse gas emissions, contributing ~50% and ~60% of all anthropogenic methane (CH4) and nitrous oxide (N2O), respectively. Apart from their significant contribution to anthropogenic greenhouse gas emissions, the energy lost as CH4 and total N losses are two of the most significant inefficiencies remaining in ruminant production systems. A number of options are reviewed for reducing enteric CH4 and N2O production from ruminant production systems, mainly focused around breeding, feeding, animal management, soil and fertiliser management and rumen manipulation. In order to fully assess the net abatement potential, each strategy needs to be subjected to whole farm systems modelling and a full life cycle assessment, to ensure that a reduction in emissions at one point does not stimulate higher emissions elsewhere in the production system. Most of the options reviewed require many years of research before practical options and commercially viable products are available for implementation on farm. This paper reviews the options for livestock production to reduce CH4 and N2O emissions, while further improving production, highlighting research issues and the need for a systems approach to the evaluation of the relative merits of abatement options.

Scaling up Molecular Epidemiology of Lassa Fever Virus among High Risk Groups in Abuja F.C.T. "Are These Challenges Summontable?"

Haemoharrgic fever virus disease caused by Lassa virus that belong to the Arena virus family, is now a big threat to human existence in Africa if not the whole world. The painful aspect in the management of this disease in Nigeria and other parts of Africa is the lack of the state of arts equipment required for diagnosis and the relatively poor attitude of stakeholders in giving it the attention it deserves! This work critically examined the scaling up processes necessary in terms of the Molecular Epidemiology of the Lassa Fever Virus among high risk groups in Abuja F.C. T. , challenges ahead, and strategies that must be put in place in nipping the task on the bud. As no drug has been approved yet by FAD i.e. Food and Drug for combating the Lassa fever virus disease; developing a preventative vaccine for researchers, health care providers and their patients therefore becomes imperative. Although, this work is a proposal, implementation of ideas raised here could be a giant step forward in curtailing the threat of haemoharrgic fever virus diseases, not only limited to Lassa virus disease, but others such as Marburg, Ebola, Dengue, Yellow fever, e.t. c.
Title Is non-parametric hypothesis testing model robust for statisticalfault localization ?

Fault localization is one of the most difficult activities in software debugging. Many existing statistical faultlocalization techniques estimate the fault positions of programs by comparing the program feature spectra between passed runs and failed runs. Some existing approaches develop estimation formulas based on mean values of the underlying program feature spectra and their distributions alike. Our previous work advocates the use of a nonparametric approach in estimation formulas to pinpoint fault-relevant positions. It is worthy of further study to resolve the two schools of thought by examining the fundamental, underlying properties of distributions related to fault localization. In particular, we ask: Can the feature spectra of program elements be safely considered as normal distributions so that parametric techniques can be soundly and powerfully applied? In this paper, we empirically investigate this question from the program predicate perspective. We conduct an experimental study based on the Siemens suite of programs. We examine the degree of normality on the distributions of evaluation biases of the predicates, and obtain three major results from the study. First, almost all examined distributions of evaluation biases are either normal or far from normal, but not in between. Second, the most fault-relevant predicates are less likely to exhibit normal distributions in terms of evaluation biases than other predicates. Our results show that normality is not common as far as evaluation bias can represent. Furthermore, the effectiveness of our non-parametric predicate-based fault-localization technique weakly correlates with the distributions of evaluation biases, making the technique robust to this type of uncertainty in the underlying program spectra.
Infertility Childhood outcomes of assisted reproductive technology

There is a large population of children conceived via assisted reproductive technology (ART), which continues to increase worldwide, without a clear understanding of associated long-term outcomes. ART children are more likely to be the result of multiple pregnancies, and thus to be born prematurely or low birthweight. There is growing evidence that ART children are phenotypically and biochemically different from naturally conceived children, but the mechanism(s) leading to these changes have not been elucidated. There is a possible increased risk of rare imprinted gene disorders in these children. However, it remains unclear whether more subtle changes in DNA methylation occur commonly, leading to differences in gene expression and phenotype in ART children. Although an increased risk of cancer among ART children has been reported, the role of ART in the development of cancer has not been demonstrated. Further research and ongoing surveillance of ART children is essential to better understand the possible effects of ART on the long-term health of this population.
3 D interconnect technology based on low temperature copper nanoparticle sintering

We explore a methodology for patterned copper nanoparticle paste for 3D interconnect applications in wafer to wafer (W2W) bonding. A novel fine pitch thermal compression bonding process (sintering) with coated copper nanoparticle paste was developed. Most of the particle size is between 10-30 nm. Lithographically defined stencil printing using photoresist and lift-off was used to apply and pattern the paste. Variations in sintering process parameters, such as: pressure, geometry and ambient atmosphere, were studied. Compared to Sn-Ag-Cu (SAC) microsolder bumps, we achieved better interconnect resistivity after sintering at 260 °C for 10 min, in a 700 mBar hydrogen forming gas (H2/N2) environment. The electrical resistivity was 7.84 ± 1.45 μΩ∙cm, which is about 4.6 times that of bulk copper. In addition, metallic nanoparticle interconnect porosity can influence the electrical properties of the interconnect. Consequently, we investigated the porosity effect on conductivity using finite element simulation. A linear relationship between the equivalent conductivity and particle overlapping ratio was found.
