Attentional and Ocular Movements

The relationship between eye movements and movements of attention was examined in a series of 6 experiments. A temporal order judgment technique was used to index attentional allocation. The results showed that endogenous movements of attention were slower than movements of the eyes and that the participants were able to hold attention at one location while executing an eye movement to another location. Under conditions of exogenous cueing, attention moved rapidly to the cued location, in advance of the eyes. These findings challenge the prevailing view that ocular movements must necessarily be preceded by a movement of The human visual system has two means by which to sample information from a scene, ocular and attentional. Ocular sampling involves movements of the eyes and consists of a series of fixations from one location to another. Attentional sampling has been described as a movement of an attentional spotlight (Posner, Snyder, & Davidson, 1980) or beam (Eriksen & Yeh, 1985) or as the repositioning of an attentional gradient (LaBerge & Brown, 1989). An important issue concerns the relationship between the ocular and the attentional systems and the manner in which the two systems interact. It is accepted that the ocular system does not constrain the attentional system insofar as attention can be moved in the visual field while the eyes remain fixated at one position. The extent to which attention constrains eye movements, however, has not been resolved. One possibility is that the eyes cannot be moved to an unattended location in the visual field; that is, prior to each saccade, attention must move ahead of the eyes to select the next fixation location. Another possibility is that eye movements can occur independently of attention such that the eyes can be moved to a location in the visual field that has not been targeted by attention. In the present research, we studied whether saccadic eye movements can occur independently
Auditory Collaborative Surfaces

Interactive tabletops offer unique collaborative features, particularly their size, geometry, orientation and, more importantly, the ability to support multi-user interaction. Although previous efforts have been made to make interactive tabletops accessible to blind people, the potential to use them in collaborative activities remains unexplored. In this paper, we present the design and implementation of a multi-user screen reader for interactive tabletops, supporting three feedback modes that vary on how much information about the partners’ actions is conveyed. We conducted a user study with ten blind people to assess the effect of feedback modes on workspace awareness and task performance. Furthermore, we analyze the type of awareness information exchanged and the emergent collaboration strategies. Finally, we provide implications for the design of future tabletop collaborative tools for blind users.
Mechanism of interferon-gamma action in control of trypanosoma cruzi infection

A real-time PCR technique that allows for accurate and sensitive quantitation of tissue parasite burden in animals infected with the protozoan parasite Trypanosoma cruzi was developed. The utility of this method was demonstrated by confirmation of higher parasite load in mice with acute infections in comparison to chronically infected mice, detection of tissuerestricted parasite persistence in different parasite:host strain combinations, and the observation of increased tissue parasite burden with higher infective doses. This method should be a useful tool for monitoring parasite burden in hosts under various treatment regimens. Introduction Infection with the protozoan Trypanosoma cruzi generally results in an acute phase, wherein parasites are relatively plentiful both in the peripheral blood and in tissues, followed by a chronic stage during which parasites are difficult to detect in either the blood or tissue. A variety of methods that have been used to detect T. cruzi in tissues, including haematoxylin and eosin staining, in situ PCR and competitive PCR. Although useful for making a qualitative evaluation for the presence of T. cruzi, none of these methods are reliable for quantitative purposes. Competitive quantitative PCR is generally considered to be at best semi-quantitative since the calculation of amplified product is limited to the plateau phase of the amplification reaction. Alternatively, real-time PCR acquires data at each cycle of the PCR reaction, allowing for calculation of product amount from the log-linear region of the amplification curve. In this study, we evaluate real-time PCR as a method to quantify the amount of T. cruzi in tissue samples from infected mice. During the acute phase of T. cruzi infection, parasites are distributed throughout most tissues of the body (22, 96, 111). However, in both animal models and in humans as the chronic
Isolation of .the Rb-r.elated p 130 through its mteraeuon wlUl CDK2 and eyelins

A two-hybrid protein interaction screen was used to isolate cDNAs encoding human proteins that can interact with human CDK2 in yeast. A new member of the retinoblastoma susceptibility gene family, Rbr-2 (Rb-related), was obtained. The sequence of the Rbr-2 protein shares -50% identity with p107 and homology to Rb within the pocket domain. Several lines of evidence indicate that Rbr-2 is the adenovirus E1A-associated p130. Like Rb and p107, p130 Rbr-2 can bind to viral oncoproteins, SV40 large T antigen, and adenovirus E1A through its pocket domain. Although p130 Rbr'2 does not bind to CDK2 in vitro, it can interact with cyclins, with a clear preference for D-type cyclins. Because both CDK2 and p130 Rbr'2 show affinity for cyclins, we suggest that p130 Rbr'2 and CDK2 interacted through a yeast-derived cyclin bridge in the two-hybrid screen. The gene encoding p130 Rbr'2 mapped to 16q13, a region of frequent genomic alteration in human tumors.
COMPARISON OF NATIVE AND INVASIVE SPECIES OF AEDES ALBOPICTUS USING DATA MINING; DERIVING THEIR GENETIC VARIATION FROM COI SEQUENCE VARIABILITY

In this study, Apriori algorithm was employed to genetic sequence patterns of Aedes albopictus (Asian tiger mosquito, Skuse, Dengue fever vector) in native and invasive ranges. It has spread widely across the world from its native region, South-east Asian countries, to every continent except Antarctica. To find the congruity of the species and their origins, I decided to compare them. To analyze the short-term genetic mutations, mtDNA was used to derive the pattern.

Yeasts isolated from Vitis vinifera L. grapes cultivated in Brazilian Equatorial region

The Sao Francisco Submid Valley is located in Bahia and Pernambuco states , and it is one of most promising regions for wine production in Brazil. It is still unknown the capability of this region in producing wine by spontaneous fermentation, and generating a product with typical regional characteristics. This study aimed at isolating and identifying the yeasts contaminating the peel of grapes Vitis vinifera L. cultivated in the Valley of the Sao Francisco Submid, Brazil. The isolates were identified based on morpho-physiological characteristics, growth ability in culture medium L-lysine agar, and biochemical identification by means of physiological tests (glucose fermentation ability, assimilation of carbon and nitrogen sources, osmotolerance and thermotolerance). Sixty yeasts isolates were detected on yeast extract-malt extract (YM) agar, and all of them belonged to non-Saccharomyces group. Physiological tests showed that 20 of 60 isolates did not grouped into any genera; and 40 isolates were suggestively identified as belonging to Hanseniaspora spp. Of 40 isolates, 17 were suggestively classified into Hanseniaspora guilliermondi species. The microbiota found on the grapes peel, grown in this region, is predominantly non-Saccharomyces yeasts, specifically Hanseniaspora spp.
SCREENING FOR FECGH MUTATION OF GROWTH DIFFERENTIATION FACTOR 9 GENE IN IRANIAN GHEZEL SHEEP POPULATION

Background: Ghezel sheep are highly prolific and one of the local sheep breeds in Iran and Turkey. Growth differentiation factor-9 (GDF9) gene has been found to be essential for growth and differentiation of early ovarian follicles. Novel mutations in GDF9 have been associated with increased ovulation rates and high litter sizes in heterozygous carriers. Therefore, fecundity gene for GDF9 (FecGH) mutation in GDF9 is considered as a possible candidate for the increased litter size observed in Ghezel ewes. Materials and Methods: The aim was to evaluate the frequency of recently reported SNP (FecGH) using polymerase chain reaction (PCR) single strand conformation polymorphism (SSCP) in 110 Ghezel ewes with a history of high litter size reproductive activity and 75 fertile ewes with normal reproductive activity. Results: The GDF9 gene exon II was investigated by this technique to screen whether they are FecGH (S395F) carriers or not. SSCP analysis identified four fragments that contained conformational differences; however the combined results with sequencing analysis data did not reveal the FecGH mutation (C to T) in GDF9 gene in Iranian Ghezel ewes. Conclusion: Current results confirmed that FecGH mutation is not present in the selected Iranian Ghezel sheep population and is not associated with Ghezel sheep high prolificacy performance. Therefore, this SNP may not represent a molecular marker for marker assisted selection programs

A shortcut to the Kovalevskaya curve via pencils of genus 3 curves

We present a systematic way of derivation of the algebraic curves of separation of variables for the classical Kovalevskaya top and its generalizations, starting from the spectral curve of the corresponding Lax representation found by Reyman and Semonov-Tian-Shansky. In particular, we show how the known Kovalevskaya curve of separation can be obtained, by a simple one-step transformation, from the spectral curve. The algorithm works for the general constants of motion of the system and is based on W. Barth’s description of Prym varieties via pencils of genus 3 curves. It also allows us to derive new curves of separation of variables in various generalizations of this system.
Supplement to “ Smoothed Quantile Regression with Large-Scale Inference ”

As noted in Section 3.1, the smoothing bias is of order h2 when a non-negative kernel is used. The ensuing empirical loss β 7→ (1/n) ∑ni=1(ρτ ∗ Kh)(yi − 〈xi,β〉) is not only twice-differentiable and convex, but also (provably) strongly convex in a local vicinity of β∗ with high probability. Kernel smoothing is ubiquitous in nonparametric statistics. The order of a kernel, ν, is defined as the order of the first non-zero moment. The order of a symmetric kernel is always even. A kernel is called high-order if ν > 2, which inevitably has negative parts and thus is no longer a probability density. Thus far we have focused on conquer with second-order kernels, and the resulting estimator achieves an `2-error of the order √ p/n + h2. Let G(·) be a higher-order symmetric kernel with order ν ≥ 4, and b > 0 be a bandwidth. Again, via convolution smoothing, we may consider a bias-reduced estimator that minimizes the empirical loss β 7→ Q̂b (β) := (1/n) ∑n i=1(ρτ ∗ Gb)(yi − 〈xi,β〉). This, however, leads to a non-convex optimization. Without further assumptions, finding a global minimum is computationally intractable: finding an -suboptimal point for a k-times continuously differentiable loss function requires at least Ω{(1/ )p/k} evaluations of the function and its first k derivatives, ignoring problem-dependent constants; see Section 1.6 in Nemirovski and Yudin (1983). Instead, various gradient-based methods have been developed for computing stationary points, which are points β with sufficiently small
Fixpoint Node Selection Query Languages for Trees

The study of node selection query languages for (finite) trees has been a major topic in the recent research on query languages for Web documents. On one hand, there has been an extensive study of XPath and its various extensions. On the other hand, query languages based on classical logics, such as first-order logic (FO) or Monadic Second-Order Logic (MSO), have been considered. Results in this area typically relate an XPath-based language to a classical logic. What has yet to emerge is an XPath-related language that is as expressive as MSO, and at the same time enjoys the computational properties of XPath, which are linear time query evaluation and exponential time query-containment test. In this paper we propose muXPath, which is the alternation-free fragment of XPath extended with fixpoint operators. Using two-way alternating automata, we show that this language does combine desired expressiveness and computational properties, placing it as an attractive candidate for the definite node-selection query language for trees.
SHALLOW (< 55 KM) SEISMIC ACTIVITY TRIGGERED ALONG THE MARASESTI-GALATI-BRAILA LINEAMENT IN RESPONSE TO THE MAJOR SUB-CRUSTAL EARTHQUAKES OF VRANCEA AREA

Introduction Earthquake triggering is the process by which stress changes associated with an earthquake can induce or retard seismic activity in the surrounding region, or trigger other earthquakes at great distances. In the case of the sub-crustal seismogenic volume of Vrancea area, a Coulomb Failure Stress analysis has been performed by Wustefeld (2003), and Wuestefeld et al., (2003), in order to determine whether the major (6.9 ≤ Mw ≤ 7.4) seismic events which had occurred in that region during the last 70 years had been independent, or if they had been triggered by the preceding large earthquakes. More recently, Radulian et al. (2007, 2008) have noticed that the intermediate-depth Vrancea earthquakes exhibited a non-random distribution of their hypocenters, a setting which could not be explained by stress transfer associated to a simple mechanical rupture process. By performing a seismicity pattern analysis, the latter authors additionally inferred that the strong earthquakes in the upper part of the Vrancea sub-crustal seismogenic volume (such as the 1977 earthquake, or the 1990 earthquake) seem to have been generated in response to the preceding large shocks having occurred below (in 1940 and in 1986, respectively); all in all, there was inferred that the seismicity configuration at shallower depths (including the crust) should correspond to that particular triggering mechanism. In the following, we provide new evidence that at shallow (crustal) levels, a significant seismic activity is triggered in response to the major earthquakes generated at intermediatedepth in Vrancea area. The crustal region which we identified as being concerned by that seismic triggering processes is located along the so-called “Marasesti-Galati-Braila Lineament” (MGBL).

Heat absorbing flat solar collector tubes hydraulic analysis has shown, that using the heat transfer standard size there might be located the pipeline, the length of which 2.5 times more than of the collector's body, sufficiently increasing at that insolation time on the transfer media.
From the Lab Notebook: Observations on Tactile Sensing for Robotic Manipulation

Manipulation is having a moment. Over the last decade, academic and commercial players alike have renewed interest in robotic manipulation due to a variety of factors: increasing availability of robotic arms, standardization of grippers, and decreasing cost of compute power. One of the key challenges that remain is making manipulators robust and safe for interaction in unstructured environments. Tactile sensors, by augmenting visual perception with shape, texture, compliance, temperature, vibration, and/or force feedback, are a vital step towards making robotic manipulators useful outside the lab sandbox. As a reflection on tactile sensing for robotic manipulation, this paper has two goals: 1) to provide practical advice on choosing a tactile sensor design, and 2) to discuss prevalent sensing archetypes and trends through a historical lens. We conclude this paper with a discussion of future research questions and community goals given trends in tactile sensor design.
Relation between parameters of body composition and echocardiography in patients with nonvalvular atrial fibrillation

Purpose: Both nutritional status and echocardiographic parameters are associated with the risk of atrial fibrillation (AF). The aim of this study was to determine the relationships between parameters of transthoracic echocardiography and nutritional status assessment as risk factors for AF. Methods: This cross-sectional study considered 120 consecutive patients hospitalized due to AF and 240 inpatients admitted due to exacerbation of cardiovascular conditions. Echocardiographic parameters and parameters of nutritional status were determined for each patient. Results: Patients in the lowest body mass index (BMI) quartile and without visceral adiposity had the lowest standard echocardiographic parameters; however, the majority of these differences disappeared after the parameters were indexed to BSA. In logistic regression analysis echocardiographic parameters were associated with slightly higher or similar AF risk comparing with parameters of nutritional status assessment. When comparison was made in relation to cut-off values obtained in ROC analysis, then having a visceral adipose tissue (VAT) score ≥ 12 was associated with lower increase in AF risk (odds ratio [OR]; 95% confidence interval [CI]: 3.09; 1.85-5.15) than the risk increase associated with e.g. left atrium diameter greater than 45mm ([OR; 95% CI] 10.483; 6.308-17.421). Conclusions: The unitary values of echocardiographic and body composition parameters only slightly differed in relation to the risk of AF occurrence, however the use of cut-off values significantly increases an impact of echocardiography on prediction of AF. The U-shaped relationships between patient’s nutritional status and AF occurrence cannot be explained by the effect of body mass on cardiac structure and size.
