Cognitive Neurophysiologic Synchronies

Objective: Cognitive neurophysiologic synchronies (NS) are low-level data streams derived from electroencephalography (EEG) measurements that can be collected and analyzed in near real time and in realistic settings. The objective of this study was to relate the expression of NS for engagement to the frequency of conversation between team members during Submarine Piloting and Navigation (SPAN) simulations. Background: If the expression of different NS patterns is sensitive to changes in the behavior of teams, they may be a useful tool for studying team cognition. Method: EEG-derived measures of engagement (EEG-E) from SPAN team members were normalized and pattern classified by self-organizing artificial neural networks and hidden Markov models. The temporal expression of these patterns was mapped onto team events and related to the frequency of team members’ speech. Standardized models were created with pooled data from multiple teams to facilitate comparisons across teams and levels of expertise and to provide a framework for rapid monitoring of team performance. Results: The NS expression for engagement shifted across task segments and internal and external task changes. These changes occurred within seconds and were affected more by changes in the task than by the person speaking. Shannon entropy measures of the NS data stream showed decreases associated with periods when the team was stressed and speaker entropy was high. Conclusion: These studies indicate that expression of neurophysiologic indicators measured by EEG may complement rather than duplicate communication metrics as measures of team cognition. Application: Neurophysiologic approaches may facilitate the rapid determination of the cognitive status of a team and support the development of novel adaptive approaches to optimize team function.
Studies on Lipochromes: IV. The Nature of the Pigments in Certain Organs.

In previous papers the works of Willstiitter and Stoll,' Van den Bergh and Snapper,2 Palmer and his associates,3 and others, have been referred to, and the methods, in part, by which they have established the identity of the lipochrome pigments with the carotin and xanthopyll of plants have been mentioned. I have been able to demonstrate the presence of carotin by chemical means in the liver, spleen, adrenal glands, corpus luteum, skin and fat, using a method which seems to be satisfactory for its quantitative estimation, at least for purposes of comparison.4 But many tissues which are commonly said to contain lipochrome are not amenable to chemical examination because of their close association with other carotincontaining tissues, or because of the small amount present in the body. It was therefore necessary to resort to histologic methods to demonstrate the presence or absence of the pigment in such tissues. By the application of methods previously described,5 and by chemical examinations, I have been able to confirm the presence of lipochrome in the tissues just mentioned but could not demonstrate it satisfactorily in the heart, ganglion cells, seminal vesicles, or in any other tissues which are commonly said to contain this substance. The pigment present in these last organs, as is well known, is a yellow to brown granular substance which is frequently tinged with fat stains, and therefore has been called lipochrome in this country, and lipofuscin in Germany. These two names are used to designate the substance in most English and American literature, but they actually represent different pigments. Borst originated the term "Lipofuscin " (Hueck 6) because he thought it was derived from some sort of lipoid. Sehrt7 named it "fat-binding wear-and-tear pigment" (fekthaltige Abnutzungspigment), and Lubarsch8 used this term for over twenty years. From time to time during this period the question has been taken up in Lubarsch's laboratory and varying results
Bryophyte response to eastern hemlock decline caused by hemlock woolly adelgid infestation1

Abstract The understory conditions of eastern hemlock stands in the Delaware Water Gap National Recreation Area have been altered by canopy decline caused by an exotic insect pest, the hemlock woolly adelgid. We consider the response of bryophytes to these changes, particularly increased availability of understory light and coarse woody debris (CWD). Pre-adelgid surveys and environmental measurements were taken at a network of 72 permanent plots in 1994 and 1995. Re-measurement of understory variables was conducted in 2003 and 2006. Bryophytes have responded to adelgid impacts through a sustained increase in plot-level richness, mainly achieved through a greater frequency of species occurring on CWD and to a lesser extent on bare soil in the plots. Greater gains in species richness took place in plots closer to the streams. Bryophyte responses to understory light availability and shrub density suggest that light availability may be more important for species maintenance than for species colonization. Orthodicranum montanum (Hedw.) Loeske had the greatest increase in frequency, occurring in two-thirds of all plots on one or more substrata by 2006. Several nitrophilous species had appeared by 2003 and 2006 including Brachythecium rutabulum (Hedw.) Schimp. , which has now colonized almost one-third of the plots since the hemlock woolly adelgid invasion. Bryophytes are a significant component of the understory vegetation in eastern hemlock stands and this study is the first to document the dynamic nature of their response to hemlock woolly adelgid impacts.
The Mini Nutritional Assessment (MNA) after 20 years of research and clinical practice

Nutritional assessment in older people to detect malnutrition or risk of malnutrition is essential to avoid adverse nutrition-related outcomes. Poor nutritional status appears to be a major contributing factor for poor prognosis in malnourished individuals. Nowadays, nutritional assessment is considered to be one of the domains which should be evaluated in comprehensive geriatric assessment (CGA). CGA is a comprehensive assessment tool with the capacity of detecting impairments in older people and, at the same time, suggest interventions. Although many assessment tools are proposed, those used in CGA are not widely agreed. After 20 years of clinical practice and research, the Mini Nutritional Assessment (MNA) seems to be the tool most widely accepted by health carers and patients for the assessment of nutritional impairment in CGA.
ROTATION OF COMET 103P/HARTLEY 2 FROM STRUCTURES IN THE COMA

The CN coma structure of the NASA EPOXI mission target, comet 103P/Hartley 2, was observed during 20 nights from 2010 September to December. These CN images probe the rotational state of the comet's nucleus and provide a ground-based observational context to complement the EPOXI observations. A dynamically excited cometary nucleus with a changing rotational rate is observed, a characteristic not seen in any comet in the past. The lack of rotational damping during the four-month observing interval places constraints on the interior structure of the nucleus.
A J‐function for Inhomogeneous Spatio‐temporal Point Processes

We propose a new summary statistic for inhomogeneous intensity‐reweighted moment stationarity spatio‐temporal point processes. The statistic is defined in terms of the n‐point correlation functions of the point process, and it generalizes the J‐function when stationarity is assumed. We show that our statistic can be represented in terms of the generating functional and that it is related to the spatio‐temporal K‐function. We further discuss its explicit form under some specific model assumptions and derive ratio‐unbiased estimators. We finally illustrate the use of our statistic in practice. © 2014 Board of the Foundation of the Scandinavian Journal of Statistics
Tractable Distributionally Robust Optimization with Data

We present a unified and tractable framework for distributionally robust optimization that could encompass a variety of statistical information including, among others things, constraints on expectation, conditional expectation, and disjoint confidence sets with uncertain probabilities defined by φ-divergence. In particular, we also show that the Wasserstein-based ambiguity set has an equivalent formulation via our proposed ambiguity set, which would enable us to tractably approximate a Wasserstein-based distributionally robust optimization problem with recourse. To address a distributionally robust optimization problem with recourse, we introduce the tractable adaptive recourse scheme (TARS), which is based on the classical linear decision rule and can also be applied in situations where the recourse decisions are discrete. We demonstrate the effectiveness of the TARS in our computational study on a multi-item newsvendor problem.
Social enterprise versus social entrepreneurship: An examination of the ‘why’ and ‘how’ in pursuing social change

This article critically considers distinctions between, social enterprise and social entrepreneurship from a theoretical perspective. Using case study analysis of 10 non-governmental organisations the paper explores these concepts empirically. Findings on social enterprise reveal a focus on the purpose of social businesses, while findings on social entrepreneurship reveal an emphasis on the processes underlying innovative and entrepreneurial activity for social purposes. Discussion of these findings indicates important developments relevant to informing the growing area of social enterprise and social entrepreneurship research. Implications extend to understanding the need for action to achieve social change, and an acceptance of risk when existing actions fail to achieve their intended outcomes.
Performance simulations of a mobile radio network using contention-based WIMA protocol under Rayleigh- and log-normal-fading environments

The performance of mobile radio network using the contention-based wireless integrated multiple access (WIMA) protocol on a packet reservation basis for frequency division duplex (FDD) hierarchies in Rayleigh- and log-normal-fading environments is simulated. The contention-based movable-boundary WIMA protocol is applied for an exiting mobile radio network to provide the data service and to compare its expected data-packet delay with those of the fixed-boundary WIMA and General Packet Radio Service (GPRS) protocol. The simulation results demonstrate that the mobile radio network using the contention-based movable-boundary WIMA protocol to integrate voice and data services can reduce the expected data-packet delay. The analytical results are used to validate the simulation results.
Design and Performance Analysisof OFDM-based Single mode and Multimode Optical Fiber Communication System

Orthogonal Frequency Division Multiplexing(OFDM) has recently emerged in optical communication to support high data transmission rates over the dispersive channels. The OFDM technique provides combat to the various limitations such as chromatic dispersion, modal dispersion etc. existing in optical communication system. In order to achieve the improved performance of optical OFDM system, the effect of parameters related to laser source and optical fiber and nonlinearities of Mach-Zehnder Modulator(MZM) etc. must be considered in detail. Despite many advantages of OFDM technique, it has major drawbacks of high peak-to-average power ratio, sensitivity to carrier frequency offset and phase noise. This paper presents optical-OFDM system design for both single mode and multimode fibers along with the analysis of different modelling parameters and various performance parameters like Bit Error Rate (BER), Q factor etc. Further, effect of MZM nonlinearities on the system performance is also considered. Keywords:Optical OFDM (O-OFDM), Quadrature Amplitude Modulation(QAM), Mach-Zehnder Modulator (MZM), Fast Fourier Transform (FFT), Inverse Fast Fourier Transform (IFFT), Intersymbol Interference (ISI), Bit Error Rate (BER).
Advanced software tools for parametric identification based on quantized data

Parametric estimation of signals, based on quantized data, is often carried out by means of least squares (LS) or averaging techniques. Such an approach often leads to optimal performance, resulting in almost unbiased estimators when the quantization error can approximately be modeled as an additive white Gaussian noise, or when other additive white Gaussian noise sources are larger than the quantization error. When such hypotheses are not satisfied, however, averaging may produce suboptimal, and biased estimators. In such a case, maximum likelihood or quantile based identification techniques can be shown to lead to more performing estimators, mostly unbiased and with a lower mean square error than that of an LS estimator. A software tool is presented, capable of estimating a DC level, a DC level corrupted by Additive White Gaussian Noise (AWGN), and sinewave parameters when the frequency is known, using data quantized by a nonuniform ADC.
Characterization of Bacillus licheniformis 6346 Mutants Which Have Altered Lytic Enzyme Activities

Two groups of mutants altered in lytic enzyme activities have been isolated from Bacillus licheniformis 6346 MH-1 by screening clones for halo production in agar plates containing cell wall conjugated with Procion brilliant red. In the first group which produced halos during colony formation, two were shown to contain three- and eightfold more muramyl-l-alanine amidase than the parent. These strains liberated amidase and intracellular α-glucosidase into the culture medium during exponential growth in liquid medium. Isolated walls had a normal qualitative composition and in autolysing liberated N-terminal amino acids and reducing groups. Wall preparations from the second group of mutants which did not produce halos lysed very poorly at pH 9.5, the optimal pH for amidase activity, and poorly at pH 5.5 even though they had similar endo-N-acetylglucosaminidase activities to the parent. Two of these strains that were also deficient in phosphoglucomutase had only 3 to 5% of the membrane-bound amidase activity compared with that in the parent. Cell walls of the phosphoglucomutase-deficient mutants treated with sodium dodecyl sulfate to inactivate endogenous lytic enzymes were dissolved at 10% of the rate of those from the parent by added amidase, but their sensitivities to lysozyme were similar. Those from one mutant had 10 to 20% of the amidase-binding capacity of parent walls, whereas its isolated mucopeptide was essentially inactive in this respect. The failure of these phosphoglucomutase-deficient mutants to autolyse is likely to be due to the combined effects of both low amidase activity and resistant walls. As a result, daughter cells are unable to separate and long chains are formed during exponential growth.

Pituitary adenylate cyclase‐activating polypeptide counteracts the impaired adult neural stem cell viability induced by palmitate

Diabetes and obesity are characterized by hyperlipidemia and represent risk factors for premature neurological disorders. Diabetic/obese animals have impaired adult neurogenesis. We hypothesize that lipotoxicity leading to neurogenesis impairment plays a role in the development of neurological complications. If so, normalizing neurogenesis in diabetes/obesity could be therapeutically useful in counteracting neurological dysfunction. The goal of this study was to determine the potential of pituitary adenylate cyclase‐activating polypeptide (PACAP) to protect adult neural stem cells (NSCs) from lipotoxicity and to study the expression of PACAP receptors in NSCs under lipotoxic conditions in vitro and in the subventricular zone in vivo. The viability of NSCs isolated from the adult mouse brain subventricular zone was assessed in the presence of a high‐fat milieu, as mimicked by palmitate, which characterizes diabetic lipotoxicity. Regulation studies of PACAP receptors were performed by quantitative PCR on NSCs in vitro or on subventricular tissues isolated from obese ob/ob mice and their lean littermates. We show that palmitate impairs NSC viability by promoting lipoapoptosis. We also show that PACAP counteracts lipotoxicity via PAC‐1 receptor activation. Studies on PACAP receptor expression revealed that PAC‐1 and VPAC‐2 are expressed by NSC in vitro and are upregulated by palmitate treatment and that PAC‐1, VPAC‐1, and VPAC‐2 are expressed in the subventricular zone/striatum in vivo and are upregulated in ob/ob mice. The present study reveals a previously uncharacterized role of PACAP to protect NSC from lipotoxicity and suggests a potential therapeutic role for PACAP receptor agonists in the treatment of neurological complications in obesity and diabetes. © 2011 Wiley Periodicals, Inc.
Small ruminants ownership pattern and level of veterinary consultation under traditional system of management in Ondo and Ekiti state of Nigeria

Ownership pattern and level of veterinary consultation among small ruminant farmers under the traditional system of management was assessed in Ondo and Ekiti states. Data from One hundred and ninety six (196) purposively sampled households were presented using frequency tables and percentages. Regression analysis was used to determine factors influencing level of veterinary consultation. Results revealed that 100% of the household's owned goats while 54% of the households kept sheep. Mean household size was 7 persons while females (65%) owned more small ruminants. Mean number of sheep kept per household was 4±5.0 while that for goats was 10±6. Only 50.5% of the households made veterinary consultations. Forty seven percent of these do regular veterinary consultations while the rest consulted occasionally. Significant positive correlations were found between household size and number of goats (r = 0.57, p

ABSTRACT Bacillus cereus is a prevalent, soil-dwelling, Gram-positive bacterium. Some strains are harmful to humans and cause food-borne illness, while other strains can be beneficial as probiotics for animals. To gain insight into the bacterial genetic determinants, we report the genome sequence of a strain, LCT-BC244, which was isolated from CGMCC 1.230.
Overexpression of ID1 reverses the repression of human dental pulp stem cells differentiation induced by TWIST1 silencing.

Multiple studies showed that the cessation of TWIST1 expression is the prerequisite for osteoblasts' maturation. However, recent reports revealed that the function of TWIST1 is different in the dental pulp stem cells (DPSCs), where a high level of TWIST1 expression promoted DPSCs' differentiation. The aim of the study was to investigate the impact of TWIST1 and ID1 on the differentiation process in the human DPSCs. METHODS TWIST1 and ID1 expression in the DSPCs was modulated by lentivirus transduction. Genes expression was assessed with qRT-PCR. The proteins level was evaluated by Western blot. The DPSCs differentiation was assessed with the proliferation, alkaline phosphatase (ALP) activity, and calcium concentration assays. RESULTS TWIST1 silencing suppressed the expression of ID1 and both the early and late markers of odontoblasts' differentiation detected at the transcript and protein level. The forced overexpression of ID1 increased the expression of the late markers of odontoblasts differentiation but diminished the expression of the early markers. DPCSs with the silenced TWIST1 and subsequent ID1 overexpression displayed an increase in the expression of the late markers of odontoblasts differentiation. Cells with silenced TWIST1 and overexpressing ID1 had increased activity of ALP, higher calcium concentration and decreased proliferation rate. The high level of ID1 expression might be a critical factor stimulating DPSCs differentiation and it might compensate the repressed differentiation of DPSCs caused by TWIST1 silencing. CONCLUSION The mutual correlation between the expression level of TWIST1 and ID1 might be a critical factor driving the process of the human odontoblasts' differentiation.
Heme-regulated eIF2α kinase modifies the phenotypic severity of murine models of erythropoietic protoporphyria and β-thalassemia

Heme-regulated eIF2α kinase (HRI) controls protein synthesis by phosphorylating the α-subunit of eukaryotic translational initiation factor 2 (eIF2α). In heme deficiency, HRI is essential for translational regulation of α- and β-globins and for the survival of erythroid progenitors. HRI is also activated by a number of cytoplasmic stresses other than heme deficiency, including oxidative stress and heat shock. However, to date, HRI has not been implicated in the pathogenesis of any known human disease or mouse phenotype. Here we report the essential role of HRI in 2 mouse models of human rbc disorders, namely erythropoietic protoporphyria (EPP) and β-thalassemia. In both cases, lack of HRI adversely modifies the phenotype: HRI deficiency exacerbates EPP and renders β-thalassemia embryonically lethal. This study establishes the protective function of HRI in inherited rbc diseases in mice and suggests that HRI may be a significant modifier of many rbc disorders in humans. Our findings also demonstrate that translational regulation could play a critical role in the clinical manifestation of rbc diseases.
