Stick boundary conditions and rotational velocity auto-correlation functions for colloidal particles in a coarse-grained representation of the solvent

We show how to implement stick boundary conditions for a spherical colloid in a solvent that is coarse-grained by the method of stochastic rotation dynamics. This allows us to measure colloidal rotational velocity auto-correlation functions by direct computer simulation. We find quantitative agreement with Enskog theory for short times and with hydrodynamic mode-coupling theory for longer times. For aqueous colloidal suspensions, the Enskog contribution to the rotational friction is larger than the hydrodynamic one when the colloidal radius drops below 35 nm.
Two new species of Myotis (Chiroptera: Vespertilionidae) for Argentina

Seven new species of Myotis have been recently described from South America, elevating to 20 the total number of species of the genus recognized for the region. Myotis izecksohni and Myotis lavali were recently described from the States of Rio de Janeiro, Parana and Pernambuco, Brazil. These are clearly different from all other known species of the genus in their external and cranial characters, which are exactly comparable with our specimens collected in Argentina. This allows to greatly expand the known geographic distributions for these two species. The addition to Argentina of Myotis lavali with specimens collected in the Yungas ecoregion of Salta Province, and Myotis izecksohni with specimens collected in the Fields and Weedlands ecoregion of Misiones Province, increases the known ecoregions to date for the distribution of the two species.
Concept Mapping: Connecting Educators Proc. of the Third Int. Conference on Concept Mapping Concept Mapping and Expert Systems: Exploring Synergies

Concept maps and expert systems are both in the soft toolbar of knowledge modelling. We have spent nearly two decades developing our expert system shell " Doctus ". Several years ago we have seen the first concept mapping solutions and started using them very soon. Frequently we have found ourselves using both tools in a particular research or consultancy project and started to wander how the two could be combined to achieve synergies. We came up with several ideas, typically when we have faced a situation which called for one of the potential synergies. In this paper we present the first of these ideas in elaborated form of a conceptual model and we also mention few additional ideas as our plans for future research. In this first idea we combine different kinds of concept maps and our expert system in order to map organisational knowledge. The expert system here is used in machine learning mode, i.e. the resulting concept map will be capable of learning – this is our intelligent concept map. 1 Organisational Knowledge Map Let's try to construct an organisational knowledge map. In the first part of it we will combine ideas from the various mapping approaches. The first is the cognitive mapping, a form of which has been developed by Eden (see Eden, 1988 for historical summary) based on Kelly's (1955) conception of personal psychological constructs and the Repertory Grid developed by Fransella and Bannister (1967). (See also Eden & Ackermann, 1998; Bryson et al., 2004) These cognitive maps can be, in a sense, considered as subsets of more extensive use of causal mapping, e.g. in the case we are mapping knowledge of a group of people. (Ackermann & Eden, 2004) A product related to this approach to cognitive mapping is Decision Explorer 1 ; Eden and his colleagues typically use it for supporting managers in structuring their problems for better understanding. Those who developed the various approaches to mapping knowledge typically agree that our concepts form some sort of hierarchies. Bu-zan's (e.g. Buzan & Buzan, 1995) approach puts this feature into the focus; this is why his mind maps always branch out from a single central concept. He claims that this represents the natural organisation of the human memory, which assertion would be in line with the previous discussion about taxonomies. The product developed in by Buzan is called Mind Map 2 ; it harnesses the …
The measure and significance of Bateman's principles

Bateman's principles explain sex roles and sexual dimorphism through sex-specific variance in mating success, reproductive success and their relationships within sexes (Bateman gradients). Empirical tests of these principles, however, have come under intense scrutiny. Here, we experimentally show that in replicate groups of red junglefowl, Gallus gallus, mating and reproductive successes were more variable in males than in females, resulting in a steeper male Bateman gradient, consistent with Bateman's principles. However, we use novel quantitative techniques to reveal that current methods typically overestimate Bateman's principles because they (i) infer mating success indirectly from offspring parentage, and thus miss matings that fail to result in fertilization, and (ii) measure Bateman gradients through the univariate regression of reproductive over mating success, without considering the substantial influence of other components of male reproductive success, namely female fecundity and paternity share. We also find a significant female Bateman gradient but show that this likely emerges as spurious consequences of male preference for fecund females, emphasizing the need for experimental approaches to establish the causal relationship between reproductive and mating success. While providing qualitative support for Bateman's principles, our study demonstrates how current approaches can generate a misleading view of sex differences and roles.
Destructive index: a measurement of lung parenchymal destruction in smokers.

Destruction of alveolar walls is considered by most observers to be the most important part in the definition of emphysema, yet it has never been precisely defined and quantitated. We therefore attempted to devise a reliable microscopic technique to quantitate alveolar destruction that would be both sensitive to disease and easy to perform. Using a point-count system, we obtained an index of parenchymal destruction that represents the percentage of destroyed space as a fraction of the total alveolar and duct space. We have called this measurement the destructive index (DI). In the lungs of 8 nonsmokers and 23 smokers, we quantitated the DI and compared it with the mean linear intercept (Lm) and with pulmonary function in smokers. Although Lm was not significantly different in the 2 groups, significant differences between the DI of smokers and nonsmokers (p less than 0.005) were found. In addition, the DI correlated with FEV1(-0.43, p less than 0.05), MMEF (r = -0.44, p less than 0.05), and recoil pressure at 90% TLC (r = -0.61, p less than 0.05) in smokers. These findings suggest that the destructive component of emphysema can be easily quantitated microscopically, occurs in smokers before dimensional changes are evident (i.e., increased Lm), and influences lung function. Therefore, the quantitation of this destruction (DI) could add greatly to the microscopic definition of emphysema, complementing the information given by the dimensional component of emphysema (Lm).
EnReal: An Energy-Aware Resource Allocation Method for Scientific Workflow Executions in Cloud Environment

Scientific workflows are often deployed across multiple cloud computing platforms due to their large-scale characteristic. This can be technically achieved by expanding a cloud platform. However, it is still a challenge to conduct scientific workflow executions in an energy-aware fashion across cloud platforms or even inside a cloud platform, since the cloud platform expansion will make the energy consumption a big concern. In this paper, we propose an Energy-aware Resource Allocation method, named EnReal, to address the above challenge. Basically, we leverage the dynamic deployment of virtual machines for scientific workflow executions. Specifically, an energy consumption model is presented for applications deployed across cloud computing platforms, and a corresponding energy-aware resource allocation algorithm is proposed for virtual machine scheduling to accomplish scientific workflow executions. Experimental evaluation demonstrates that the proposed method is both effective and efficient.
Online Rank Elicitation for Plackett-Luce: A Dueling Bandits Approach

We study the problem of online rank elicitation, assuming that rankings of a set of alternatives obey the Plackett-Luce distribution. Following the setting of the dueling bandits problem, the learner is allowed to query pairwise comparisons between alternatives, i.e., to sample pairwise marginals of the distribution in an online fashion. Using this information, the learner seeks to reliably predict the most probable ranking (or top-alternative). Our approach is based on constructing a surrogate probability distribution over rankings based on a sorting procedure, for which the pairwise marginals provably coincide with the marginals of the Plackett-Luce distribution. In addition to a formal performance and complexity analysis, we present first experimental studies.
Mining group correlations over data streams

Mining correlation over steams attracts a lot of attentions recently. However, group correlation analysis over data streams is relatively few. Moreover, existing literatures are mainly focused on a single time window, with large space and time complexity. This paper proposes an online canonical correlation analysis algorithm called MGDS (Mining Group Data Streams). Based on base-window, the MGDS algorithm dynamically maintains a few statistics from raw data to calculate correlation. The mining range is not limited in a single window, but can be changed according to queries. Theoretical analysis and experimental results show that the algorithm is accurate and efficient with space and time overhead reduced greatly.
Understanding and Designing Surface Computing with ZOIL and Squidy

In this paper we provide a threefold contribution to the Surface Computing (SC) community. Firstly, we will discuss frameworks such as “Reality-based Interaction” which provide a deeper theoretical understanding of SC. Secondly, we will introduce our ZOIL user interface paradigm for SC on mobile, tabletop or wall-sized devices. Thirdly, we will describe our two software tools “Squidy” and “ZOIL UI Framework” which have supported and facilitated our iterative design of SC prototypes.
A Dynamical Model of Twitter Activity Profiles

The advent of the era of Big Data has allowed many researchers to dig into various socio-technical systems, including social media platforms. In particular, these systems have provided them with certain verifiable means to look into certain aspects of human behavior. In this work, we are specifically interested in the behavior of individuals on social media platforms---how they handle the information they get, and how they share it. We look into Twitter to understand the dynamics behind the users' posting activities---tweets and retweets---zooming in on topics that peaked in popularity. Three mechanisms are considered: endogenous stimuli, exogenous stimuli, and a mechanism that dictates the decay of interest of the population in a topic. We propose a model involving two parameters η* and λ describing the tweeting behaviour of users, which allow us to reconstruct the findings of Lehmann et al. (2012) on the temporal profiles of popular Twitter hashtags. With this model, we are able to accurately reproduce the temporal profile of user engagements on Twitter. Furthermore, we introduce an alternative in classifying the collective activities on the socio-technical system based on the model.
Counting States of Near-Extremal Black Holes.

A six-dimensional black string is considered and its Bekenstein-Hawking entropy computed. It is shown that to leading order above extremality, this entropy precisely counts the number of string states with the given energy and charges. This identification implies that Hawking decay of the near-extremal black string can be analyzed in string perturbation theory and is perturbatively unitary.
Are we narrowing genetic variability in seed orchards? An attempt to answer, based on the analysis of microsatellite DNA of grafts growing in Scots pine (Pinus sylvestris L.) seed orchard in the Forest District Susz

Abstract Scots pine (Pinus sylvestris L.) is the most common species in Poland’s forest stands. The mode of pine stands renovation requires that silviculture practitioners have continuous access to seed banks. Orchard-grown seeds are predicted to constitute an increasingly larger part of the average demand for pine seeds in Poland. Seed orchards, due to a limited number of maternal trees as well as the irregularity of their blooming and pollination, enhance the risk of genetic diversity reduction in planted forest stands. This is of particular importance in the context of dynamic climate change. Markers based on microsatellite DNA fragments are effective tools for monitoring genetic variability. In the present study, three different microsatellite DNA fragments were used: SPAC 12.5, SPAG 7.14 and SPAC 11.4. The main objective of this research was to study genetic variability in one of the biggest seed orchards in Poland, located in the Forest District Susz. The obtained results indicated heterozygosity loss within the orchard, proving the existence of specimen selection effects on genetic variability. Hence, it seems quite important to take account of molecular genetic variability of maternal trees in future breeding strategies.
Chemokine receptors Ccr1, Ccr2, and Ccr5 mediate neutrophil migration to postischemic tissue

Leukocyte infiltration of reerfused tissue is a key event in the pathogenesis of ischemia‐reperfusion. However, the role of chemokine receptors Ccr1, Ccr2, and Ccr5 for each single step of the postischemic recruitment process of leukocytes has not yet been characterized. Leukocyte rolling, firm adherence, transendothelial, and extravascular migration were analyzed in the cremaster muscle of anaesthetized C57BL/6 mice using near‐infrared reflected light oblique transillumination microscopy. Prior to 30 min of ischemia as well as at 5, 30, 60, 90, and 120 min after onset of reperfusion, migration parameters were determined in wild‐type, Ccr1−/−, Ccr2−/−, and Ccr5−/− mice. Sham‐operated wild‐type mice without ischemia were used as controls. No differences were detected in numbers of rolling leukocytes among groups. In contrast, the number of firmly adherent leukocytes was increased significantly in wild‐type mice as compared with sham‐operated mice throughout the entire reperfusion phase. Already after 5 min of reperfusion, this increase was reduced significantly in Ccr1−/− and Ccr5−/− mice, whereas only in Ccr2−/− mice, was adherence attenuated significantly at 120 min after onset of reperfusion. Furthermore, after 120 min of reperfusion, the number of transmigrated leukocytes (>80% Ly‐6G+ neutrophils) was elevated in wild‐type mice as compared with sham‐operated animals. This elevation was significantly lower in Ccr1−/−, Ccr2−/−, and Ccr5−/− mice. Leukocyte extravascular migration distances were comparable among groups. In conclusion, these in vivo data demonstrate that Ccr1, Ccr2, and Ccr5 mediate the postischemic recruitment of neutrophils through effects on intravascular adherence and subsequent transmigration.
3D domain‐swapped human cystatin C with amyloidlike intermolecular β‐sheets

Oligomerization of human cystatin C (HCC) leads to amyloid deposits in brain arteries, and this process is greatly accelerated with a naturally occurring L68Q variant. The crystal structures of N‐truncated and full‐length HCC (cubic form) showed dimer formation via three‐dimensional (3D) domain swapping, and this observation has led to the suggestion that an analogous domain‐swapping mechanism, but propagated in an open‐ended fashion, could be the basis of HCC fibril formation. Here we report that full‐length HCC, when crystallized in a new, tetragonal form, dimerizes by swapping the same secondary structure elements but with a very different overall structure generated by the flexibility of the hinge linking the moveable elements. The β‐strands of the β‐cores of the two folding units of the present dimer are roughly parallel, while they formed an angle of about 100° in the previous two structures. The dimers pack around a crystallographic dyad by extending their molecular β‐sheets in an intermolecular context. At the other edge of the molecular β‐sheet, side‐chain–side‐chain hydrogen bonds propagate the β‐structure in the same direction. In consequence, a supramolecular crystal structure is generated, with all the β‐strands of the domain‐swapped dimers being perpendicular to one crystallographic direction. This observation is relevant to amyloid aggregation of HCC, as X‐ray diffraction studies of amyloid fibrils show them to have ordered, repeating structure, consistent with the so‐called cross‐β structure, in which extended polypeptide chains are perpendicular to the fiber axis and form infinite β‐sheets that are parallel to this axis.

Baduanjin Exercise for Type 2 Diabetes Mellitus: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Objective To investigate the effects of Baduanjin exercise for type 2 diabetes mellitus. Methods Literature retrieval was performed in several databases, including PubMed, EMBASE, Cochrane Library, CNKI, Wanfang Data Information Site, CBM, and VIP from inception to April 2017. Randomized controlled trials on evaluating the effects of Baduanjin exercise were identified. The primary outcomes were glycosylated hemoglobin, fasting blood-glucose, and postprandial plasma glucose. Review Manager 5.2 (RevMan 5.2) and Stata V.13. 0 software were conducted for data analysis. Results The results of the meta-analysis indicated that the effects of type 2 diabetes mellitus were favoring Baduanjin plus conventional therapy, when compared with the routine treatment. Baduanjin plus conventional therapy lowered the level of glycosylated hemoglobin, fasting blood-glucose, postprandial plasma glucose, TC, TG, and LDL-C and improved HDL-C. Adverse events were not mentioned in all included studies. No publication bias was detected by Begg's and Egger's test and no single study affected the overall result by influence analysis. Conclusions Evidence from meta-analysis suggested that Baduanjin exercise plus conventional therapy has a positive effect on type 2 diabetes mellitus. However, more rigorously designed and large sample RCTs are required to confirm the efficacy and safety in further studies.
Spectrum and energy efficiency analysis of ultra dense network with sleep

Recently, Ultra Dense Network (UDN) emerges as one of the state-of-the-art technologies to cope with the pressure of the ever-growing traffic demands in wireless communication. By deploying dense Base Stations (BSs) to provide ubiquitous coverage and high-speed transmission, it is considered as one of the most promising paradigms. However, large numbers of BSs bring the rise of the energy consumption of circuit and other costs for maintenance. Therefore, along with spectrum efficiency, the energy efficiency also becomes a major concern in UDN. In this paper, we analyze the UDN performance on both network Spectrum Efficiency (SE) and network Energy Efficiency (EE) with sleep mode. We first offer an alternative analytical expression of the average achievable rate. Then we modified the existing stochastic model where BSs and users are modeled as the Poisson Point process (PPP). Unlike the previous work, we introduce the active BSs density and show its relationship with densities of BSs and users. After that, we analytically derive the expression of the network SE and EE, and analyze the network performance through numerical simulations. We further do practical simulations to prove the validity of our analysis. In the end, we draw the conclusions that tradeoff needs to be made since different network performance metrics cannot be optimal at the same time.
