Visualizing differences between brain networks

Nowadays, it is possible to obtain brain networks from data measured by a Magnetic Resonance Imaging (MRI) scanner. This opens up new ways of understanding the human brain. One new possibility is comparing two brain networks, which may aid in understanding brain diseases like Alzheimer’s disease. We present an application designed to compare two such networks, either obtained from two people, the same person using different techniques, or the same person at a different point in time. Visualizing two brain networks is challenging because these networks are already difficult to understand on their own. The usual way to compare two large networks is by computing graph properties, such as the small-worldness. Such graph properties are only a coarse representation of a network, and many interesting properties are lost. Our application shows more information, allowing an expert to not only identify differences and their anatomical locations, but also to investigate their causes and their effects on the rest of the network.
Néel transition in (Mg,Fe)O: A possible change of magnetic structure

Abstract The Néel temperature (TN) of (Mg1-X,FeX)O and its compositional dependence have been studied with a superconducting quantum interference device (SQUID) in the temperature range 5-300 K at constant magnetic field of 1000 Oe. We determined the magnetic phase diagram at ambient pressure. As the TN constantly increased with iron content, we found a kink in the paramagnetic-antiferromagnetic boundary at around X = 0.5, which suggests a possible change of the magnetic structure in the antiferromagnetic state. We propose that the magnetic boundary ends at X = 0.12(1) and 0 K. Our results show that the pressure of the rhombohedral distortions of (Mg,Fe)O can be very sensitive to Fe content if the structure distortion is correlated to magnetic ordering
Investigating the Relationship between Sprint and Jump Performances with Velocity and Power Parameters during Propulsive Phase of the Loaded-Squat Jump Exercise.

The purpose of this study was to investigate the relationship between sprint and jump performance with velocity parameters in the loaded-squat jump exercise (SQ Loaded ). In accordance with this purpose, a total of 13 athletes competing in martial sports have participated in this study voluntarily. In this study, sprint tests, vertical jump (VJ), standing long jump (SLJ) tests and one repetition maximal strength test were applied. In order to determine velocity and power parameters, SQ Loaded exercise was applied by using an external load that corresponds to 40% of body weights of the subjects via an isoinertial velocity transducer (T-Force dynamic measurement system) and values of mean propulsive velocity (MPV), peak velocity (PV), mean propulsive power (MPP) and peak power (PP) were obtained. Descriptive statistics, Spearman correlation analysis and Shapiro-Wilk normality tests were used for data assessment. It has been concluded that there is no statistically significant relation between 10, 20 and 30 meter sprint times and the values of MPV (r= -,332; r= -,375; r= -,446; p>.05 respectively), PV (r= -,058; r= -,118; r= -,165; p>.05 respectively), MPP (r= -,285; r= -,482; r= -,485; p>.05 respectively) and PP (r= -,205; r= -,512; r= -,391; p>.05 respectively) during SQ Loaded exercise. In addition, while no statistically significant relation has been obtained between the VJ and SLJ values of the participants and MPV (r= ,496; r = ,429; p>.05 respectively) and PV (r= ,300; r= ,223; p>.05 respectively) values during propulsive stage of SQ Loaded exercise, it has been ascertained that there is a statistically positive and significant relation between the values of MPP(r= ,620; r= ,580; p>.05 respectively) and PP (r= ,678; r=,572; p<.05 respectively). In conclusion, it can be suggested that lifting velocity and power values don't have a positive effect on short sprint performance; however power values affect the vertical jump and standing long jump performances positively.
Blood Pressure Variability and Vascular Dysfunction in Essential Hypertension

❙ABSTRACT❙ There are several aspects of blood pressure. Clinically, how to best assess blood pressure average and variability is still a matter of the ongoing debate. Besides office blood pressure, we must pay more careful attention focused on hypertension with blood pressure fluctuation. Impaired endothelial function is intimately associated with the development of hypertension and atherosclerosis. In this review, we describe the relation between endothelial dysfunction and hypertension, the effect of gene polymorphism on endothelial dysfunction, the effects of antihypertensive agents and dietary supplementation on impaired endothelial function in hypertension. In order to predict the future atherosclerosis and cardiovascular events in subjects with hypertension, the adequate assessment of endothelial function is one of the most reliable markers. Furthermore, we discuss the close relationship between blood pressure variability and endothelial function. Blood pressure variability during a day or a week is an important, new risk factor for cardiovascular disease and restoring impaired endothelial function might be a target to prevent blood pressure variation and future cardiovascular events.

Consumers' and producers' expectations towards geographical indications Empirical evidence for a German case study

Purpose – This paper's objective is to investigate consumers' and producers' expectations towards geographical indications (GIs) in a German context, where this certification scheme has not been widely used so far.Design/methodology/approach – Data for the consumer side were obtained by a structured questionnaire. A total of 741 consumers were asked online with respect to their knowledge and expectations towards geographical indications in general and Hessian apple wine in particular. The collected data were analysed by an explorative factor analysis and a binary logit model. Additionally, data for the producer side were collected via an in‐depth interview with one major producer of Hessian apple wine.Findings – The consumer side results indicate that Hessian consumers' awareness and knowledge about GIs is very limited. Moreover, it is found that the quality warranty dimension is not as important as the economic support dimension and perceived authenticity of the product. A hypothetical willingness to pay.
Comparison between under 20 and Over 20 amateur football players with the use of hi-tech Gps (K-Gps 20Hz)

It is being understood that technical and tactical qualities are the most important values for a football player, anyway during the last years the physical performance became crucial to determinate the result of a game. Normally, the physiological component is a discrimination that permit to differentiate between professional and amateur player. But what are the real differences between an “Over 20 years old” and a “Under 20 years old” player, evaluated in amateur context which parameters emerge to determine the level of an athlete and which elements are crucial to move on to senior category. The performance parameters data collection, has been possible through the use of GPS (Global Position System). In our case were analyzed 6 matches in First Category championship (Marche, Italy), corresponding at the seventh level of Italian league and 6 games of the Juniors Provincial championship (Marche, Italy), using 10 GPS, 5 for each team, each divided into positions, to give larger specificity to the study. Afterward data were analyzed, dividing two control groups, substituted players (outgoing) calling them "Full Match Sub" and players who have played the entire game, calling them "Full Match".
Envelopes of cometary orbits

SUMMARY: We discuss cometary orbits from the standpoint of Nonstandard(Leibnitz) analysis, a relatively new branch of mathematics. In particular, we con-sider parabolic cometary paths. It appears that, in a sense, every parabola is anellipse.Key words. Comets: general { Methods: analytical 1. INTRODUCTIONThe standard approach to physics is based onmathematics over R, the ﬂeld of real numbers, or C,the ﬂeld of complex numbers. Both these structuresare Archimedean, i.e. they do not admit explicitlyinﬂnite quantities. In discussing the real line R wehave no way of knowing what a line in physical spaceis really like. It might be like the real line R , the hy-perreal line ⁄ R which contains inﬂnitesimals and in-ﬂnite numbers, or neither. However, in applicationsof the mathematical analysis it is helpful to imaginea line in a physical space as ⁄ R . The hyperreal lineis, like the real line, a useful mathematical model fora line in the physical space. One of the aims of thispaper is to advocate the use of methods from non-standard analysis (also known as Leibnitz analysis,non-Archimedean analysis or Robinson’s analysis) instudies of certain phenomena in astronomy. Here weshall discuss trajectories of comets.101

Embodying Social Interactions: Integrating Physiology into the Study of Connections and Relationships at Work

We review how positive social interactions at work affect the physiological functioning of employees’ cardiovascular, immune and neuroendocrine systems. We illustrate how consideration of the physiological effects of positive connections and relationships invites new research questions for leader-member exchange, mentoring, and interpersonal helping perspectives. We then raise research questions generated by gaps in the existing literature. Finally, we address the practical implications of pursuing a research agenda that integrates physiological mechanisms and measures.
NN-Based Approximate Model Control for the EAF Electrode Regulator System

This paper proposes a robust adaptive neural network controller (RANNC) for electrode regulator system. According to the characteristics of electrode regulator system, an affine-like equivalent model is first derived. Then, the nonlinear control law is derived directly based on the affine-like equivalent model identified with neural networks, which avoids complex control development and intensive computation. The control scheme is simple enough that it can be implemented on an automotive microcontroller system, and the performance meets the system requirements. The stability of the system is established by the Lyapunov method. Several simulations illustrate the effectiveness of the controller.
Ask the expert: Smoking cessation

1. If the budget is poor, the programme should target the most cost-effective interventions, ask for free radio and television presentations, collaborate with various associations (medical and social, etc.) for voluntary anti-smoking interventions. Cessation programmes can be partially charged to companies and administrations. The programme should increase the awareness of the funding agencies and of the government about the cost-effectiveness of the various types of interventions, and call for external funding agencies to be involved (e.g. the Bloomberg Foundation).
Bait visitation by Formica lemani (Hymenoptera: Fomicidae) indicates shortage of carbohydrates in alpine grasslands

Insights can be gained by analysing the feeding decisions of animals in terms of nutrient demands at a species or community level. Using carbohydrate and protein food baits, resource use and food preferences of Formica (Serviformica) lemani were determined at nine locations situated at different altitudes (1875 to 2400 m a.s.l.) in the alpine grassland belt above the tree line in Austria and northern Italy. F. lemani is the most common species of ant in this habitat. Sucrose baits placed around ant colonies were visited by significantly (3.9 times) more workers than protein baits. This indicates that sources of sugar (carbohydrate) are in short supply in the alpine zone, whereas availability of prey items appears to be less constraining. Overall, we recorded a decrease in the incidence of visits to baits from low (31.9% baits attracting ants at least once) to high altitudes (16.7%). Foraging ants never visited 51.5% of the baits exposed for periods of 75 min. This indicates that with increasing altitude competition for food among ant colonies becomes less intense in alpine grassland ant communities.
On the decidability of bigraphical sorting

Bigraphical reactive systems are a general framework for mobile, concurrent, and communicating systems based on the notions of location and channel connection. Bigraphs have been shown to be suitable for representing several formalisms, but despite their expressive power, in many cases some disciplines on the structure of bigraphs are needed to faithfully encode the computational model at hand. Sortings have been proposed as an abstract technique to discipline bigraphs. In this paper, we investigate the decidability problem of bigraphical sorting, that is, to decide whether a bigraph belongs to some sorted bigraphical category. While the problem is not decidable in general (and in particular in the case of Debois and coauthors’ predicate sortings), we propose a decidable subclass of bigraphical sortings, match predicate sortings, which can be decided using the matching algorithm for bigraphs. The proposed subclass is shown to be expressive enough to capture several bigraphical sortings present in literature, e.g., homomorphic sortings and local bigraphs.
Biogas originated from residual biomass in ecosystem services

Human demand for the provisioning services of the ecosystem has been rising and shows the existence of trade-offs in their generation. Brazil is a great producer of agricultural commodities and animal protein, which generates a large amount of residual biomass throughout the production process, especially animal highly polluting waste concentrated in small areas. Ecosystems provide a wide range of services that are of fundamental importance to the well-being, health, subsistence and survival of human beings. The impacts of the waste generated by confined animals can degrade the ecosystem and reduce the services it can supply. Using waste to generate biogas does not require direct resources from the ecosystems to generate energy. In this context, it is an energy product classified as a provisioning service and, at the same time, an ecosystem regulating service, as it mitigates undesirable effects in the environment. The main goal of the classification of biogas as an ecosystem service is to explore its contributions to the ecosystem and to human well-being.
Highly ionized disc and transient outflows in the Seyfert galaxy IRAS 18325-5926

We report on strong X-ray variability and the Fe K band spectrum of the Seyfert galaxy IRAS 18325-5926 obtained from the 2001 XMM-Newton EPIC pn observation of a 120 ks duration. While the X-ray source is highly variable, the 8-10 keV band shows larger variability than that of the lower energies. Amplified 8-10 keV flux variations are associated with two prominent flares of the X-ray source during the observation. The Fe K emission is peaked at 6.6 keV with moderate broadening. It is likely to originate from a highly ionized disc with the ionization parameter of log xi ~3. The Fe K line flux responds to the major flare, supporting its disc origin. There is a short burst of the Fe line flux with no relation to the continuum brightness for which we have no clear explanation. We also find transient, blueshifted Fe K absorption features, which can be identified with high-velocity (~0.2 c) outflows of highly ionized gas, as found in other active galaxies. The deepest absorption feature appears only briefly (~1 hr) at the onset of the major flare and disappears when the flare is declining. The rapid evolution of the absorption spectrum makes this source peculiar among the active galaxies with high velocity outflows. Another detection of the absorption feature also precedes the other flare. The variability of the absorption feature partly accounts for the excess variability in the 8-10 keV band where the absorption feature appears. Although no reverberation measurement is available, the black hole mass of 2e6 Msun is inferred from the X-ray variability. When this mass is assumed, the black hole is accreting at around the Eddington limit, which may fit the highly ionized disc and strong outflows observed in this galaxy.
A comparison of international HRM practices by Indian and European MNEs: evidence from Africa

By comparing the HRM practices in Indian and European MNE subsidiaries located in four of the Southern African Development Community countries, this paper tests the relevance of the country-of-origin effect and analyses the strength of institutional and firm-level influences. Examining data from 865 MNE subsidiaries obtained from the World Bank enterprise survey data, the paper finds that Indian MNEs have higher labour costs in relation to total sales than their European counterparts, that Indian MNEs make more use of temporary labour than their European counterparts, that Indian MNEs invest in less training than their European counterparts. No support is found for the hypothesis that Indian MNEs have a lower ratio of skilled workers in comparison to European-owned subsidiaries. The study shows that country-of-origin effects are weakened if they are not consistent with host country ideology and that as economies evolve so too do their expectations of HR policy and practices.
PRIME NUMBERS IN INTERVALS STARTING AT A FIXED POWER OF THE INTEGERS

Abstract The best known results about the distribution of prime numbers in short intervals imply that all intervals [n,n+H]⊂[N,2N] contain the expected number of primes for all H≥N7/12, and almost all intervals [n,n+H]⊂[N,2N] contain the expected number of primes for all H≥N1/6. As a natural generalization, this paper is concerned with the distribution of prime numbers in intervals of type [nα,nα+H] with α>1.
Modeling Tree Mortality Following Wildfire in the Southeastern Canadian Mixed-Wood Boreal Forest

We modeled tree mortality three months after a wildfire in the mixed-wood boreal forest (Quebec, Canada) using data from 1963 trees in 36 stands burned under a wide range of fire behavior conditions during the 1997 Val Paradis fire. Stand composition influenced the char height: height of burn was lower in deciduous stands than mixed or coniferous stands. Analysis of species mortality rates revealed that Populus tremuloides Michx. was the least fire-resistant species, whereas Picea mariana Moench and Pinus banksiana Lamb. were the most resistant species. Efficient interactions for conifers exist between crown and cambial resistance to injury and fire behavior, as diameter at breast height (DBH), total tree height (TOTH), and mean bark thickness are characteristic variables through- out the fire behavior range. The best logistic regressions, relating probability of wildfire- induced mortality to morphology and fire variables, always entered char height (CH) at the first step of the stepwise procedure, followed by a morphological variable (DBH or TOTH). The Kappa coefficient used for model validations revealed that logistic regressions using morpho- logic and fire variables were very efficient as compared to logistic regressions based only on morphologic variables. Potential applications of these results by land managers are discussed. FOR. SCI. 49(4):566-576.
Wireless sensor network design through genetic algorithm

In this paper, we used WSN design, as a multi-objective optimization problem through Genetic Algorithm (GA) technique. We examined the effects of GA parameters including population size, mutation probability, and selection and crossover methods on the design. Choosing suitable parameters is a trade-off between different network criteria and characteristics. Type of deployment, effect of network size, radio communication radius, deployment density of sensors in an application area and location of base station are the WSN’s characteristics, which were investigated in this paper. The simulation results of this study indicate that the value of radio communication radius has direct effect on radio interference, cluster-overlapping, sensor node distribution uniformity and communication energy consumption. The optimal value of radio communication radius depends on network deployment density rather than network size and deployment type. Location of the base station affects radio communication energy, cluster-overlapping and average number of communication per cluster head. BS located outside the application domain is preferred over that located inside. In all the network situations, random deployment has better performance compared to grid deployment.
Accompanying “in-service teaching” internships of prospective mathematics teachers – a model for encouraging exchange between theory and practice using the triple coaching approach

Developing professional expertise of prospective teachers not only in terms of theoretical knowledge but also in terms of competencies of designing challenging and cognitively activating learning opportunities in the mathematics classroom is certainly one of the key aims of internship phases in pre-service mathematics teacher training. As mathematics-related theoretical contents of teacher training and practice-related learning opportunities of school internships are not always linked in an optimal way, this paper aims at discussing a model of an intensive internship phase combined with a triple coaching approach partly integrated in a course accompanying the internship phase.
The Political Economy of the Vanishing Marginals: Tiebout Sorting and the American Political System

An overview of our methodology and results suggests that there does exist a trend stationary pattern of increasing vote margins driven by traditional and expanded Tiebout Sorting. First, we have found a long-term trend stationary pattern of increasing vote margins. This was followed by the discovery that within a subset of the trend, 1942 to 1992, a blunt measurement of Tiebout Sorting through the application of urban-rural differences, soliciting information regarding age, class, gender, income, occupation, and race while measuring preferences for public goods through an individual's vote, was statistically significant. Finally, we identified evidence of Tiebout Sorting of both the traditional variety (sorting based on public goods provided) and the economic, but not ideological, portion of the expanded variety (spatial sorting by ideological and economic factors).
