Development of a grid enabled chemistry application

P-GRADE development and run-time environment provides high-level graphical support to develop scientific applications and to execute them efficiently on various platforms. This paper gives an overview on the parallelisation of two simulator algorithms; for chemical reaction-diffusion systems and for accidental release of chemical (or radioactive) substances. Applying the same user environment we present our experiences regarding the execution of these chemistry applications on dedicated and non-dedicated clusters, and in different grid environments.
The Active and Periactive Zone Organization and the Functional Properties of Small and Large Synapses

The arrival of an action potential (AP) at a synaptic terminal elicits highly synchronized quanta release. Repetitive APs produce successive synaptic vesicle (SV) fusions that require management of spent SV components in the presynaptic membrane with minimum disturbance of the secretory apparatus. To this end, the synaptic machinery is structured accordingly to the strength and the range of frequencies at which each particular synapse operates. This results in variations in the number and dimension of Active Zones (AZs), amount and distribution of SVs, and probably, in the primary endocytic mechanisms they use. Understanding better how these structural differences determine the functional response in each case has been a matter of long-term interest. Here we review the structural and functional properties of three distinct types of synapses: the neuromuscular junction (NMJ; a giant, highly reliable synapse that must exocytose a large number of quanta with each stimulus to guarantee excitation of the postsynaptic cell), the hippocampal excitatory small synapse (which most often has a single release site and a relatively small pool of vesicles), and the cerebellar mossy fiber-granule cell synapse (which possesses hundreds of release sites and is able to translocate, dock and prime vesicles at high speed). We will focus on how the release apparatus is organized in each case, the relative amount of vesicular membrane that needs to be accommodated within the periAZ upon stimulation, the different mechanisms for retrieving the excess of membrane and finally, how these factors may influence the functioning of the release sites.
Us Faculty Patenting: Inside and Outside the University

This paper examines the empirical anomaly that in a sample of 5811 patents on which US faculty are listed as inventors, 26% of the patents are assigned solely to firms rather than to the faculty member's university as is dictated by US university employment policies or the Bayh Dole Act. In this paper we estimate a series of probability models of assignment as a function of patent characteristics, university policy, and inventor fields in order to examine the extent to which outside assignment is nefarious or comes from legitimate activities, such as consulting. Patents assigned to firms (whether established or start-ups with inventor as principal) are less basic than those assigned to universities suggesting these patents result from faculty consulting. A higher inventor share increases the likelihood of university assignment as compared with assignment to a firm in which the inventor is a principal but it has no effect on consulting with established firms versus assignment to the university. Faculty in the physical sciences and engineering are more likely to assign their patents to established firms than those in biological sciences.
Crime Prevention through Environmental Design (CPTED) and Secured by Design (SBD): What Works

Crime Prevention through Environmental Design (CPTED) is a crime reduction measure that aims to design out crime at the planning, or pre-planning stage. It is based upon the five key elements of creating defensible space, limiting through movement, maximising natural surveillance, managing and maintaining an area and ensuring that standards of physical security are commensurate with risk. Secured by Design (SBD) is an award scheme, delivered by police forces, that incorporates the principles of CPTED. This presentation will explore what works (and what doesn’t) in delivering CPTED and SBD. It will also explore the effectiveness of CPTED and SBD in terms of their impact on police recorded crime, self-reported crime and offender decision-making.
Principles and perspectives for the conservation of goat buck spermatozoa

This paper is focused on the use of alternative protocols for goat buck sperm cryopreservation and other current approaches to study sperm cryosurvival, considering theoretical principles for the preservation of cells at freezing temperatures. Simple modifications to traditional freeze-thawing protocols may improve sperm cryosurvival; thus, cooling to −5 ◦C instead of +5 ◦C, before freezing, improves buck, ram and boar sperm cryosurvival. Premature capacitation induced by cryopreservation may be used as an additional tool to: (1) assess new cryopreservation protocols; i.e. the least aggressive one would induce the lowest proportion of premature capacitated spermatozoa; (2) to estimate the subpopulation of frozen-thawed spermatozoa that remain fertile (live cells showing Pattern F or B; Chlortetracycline Assay). Freezing and storage of spermatozoa using ultra-low freezers (−150 ◦C) represents a feasible alternative to the use of liquid nitrogen, at least in both short and medium term. Simple tests based on simulation of osmotic stress that occurs during freeze-thawing are promising approaches to predict sperm cryosurvival. Assessment of spermatozoa during hyperosmotic and isosmotic conditions at 23 ◦C has revealed that proportions of plasma membrane-intact and acrosome-intact spermatozoa are similar to those observed after cryopreservation (after freeze-thawing). Inter-male differences in are an sperm freezability

Slope-corrected vegetation-corrected polarimetric two-scale model for soil moisture retrieval

We present a method able to retrieve the soil moisture content and the surface roughness of a moderately vegetated soil in a possibly hilly area, from a fully polarimetric SAR dataset. The estimation procedure is based on the prediction of the second order statistics of the scattered field provided by the Slope-Corrected Polarimetric Two-Scale Model combined with a two-component scattering model. The performance of the estimation method is assessed by comparing obtained retrieval results to “in situ” measurements. To this aim, data from AGRISAR 2006 campaign are employed.
Slepian-Wolf Coding for Reconciliation of Physical Layer Secret Keys

In this paper, we show how to compute the Slepian-Wolf lower bound for the reconciliation of physical layer secret keys between two radio terminals. Two coding approaches, including the syndrome method and the parity method, have been proven to require the same number of bits exchanged between two terminals for the reconciliation in the noiseless environment. We also present a practical coding approach based on LDPC codes, and the gap between the practical approach and the Slepian-Wolf bound is given.
Histological examination has a major impact on macroscopic necropsy diagnoses

Background: Necropsy is the gold standard for clinicopathological discrepancy studies and epidemiological surveys. Inadequate sampling or lack of tissue may hamper the final interpretation and quality of the necropsy. Aim: To compare the histological and gross necropsy diagnoses of different organs. Methods: A retrospective comparison of the provisional reports (gross findings only) and the final reports (after histological examination) of the necropsies performed at the department of pathology of the Hospital das Clínicas, Sao Paulo University, Brazil, a large tertiary care complex, in 2001. The total number of diagnoses listed for the lungs, heart, liver, pancreas, kidneys, and spleen were calculated. Findings were categorised into concordant/refined diagnosis, discordant/additional diagnosis, histology needed, and inconclusive. Results: Three hundred and seventy one postmortem reports were analysed. There were 214 men and 157 women, with a mean age of 50.3 years, ranging from 1 to 92. The lung received the highest number (954) and the pancreas the lowest number (390) of diagnoses. The highest frequencies of discrepancies between the gross and microscopic findings were found in the lung and the liver: 38.7% and 35.1%, respectively. The brain had the lowest frequency of discrepancies. In a small number of cases, the final diagnosis could only be achieved through microscopic analysis, with the highest frequency being found in the kidneys (8.5%). Conclusions: Histological analysis has a major impact on previously performed gross diagnosis at necropsy, especially in the lungs, liver, and kidneys. Adequate sampling and histological analysis are important for necropsy quality.
The Returns to Schooling for Displaced Workers

This paper presents new evidence regarding the benefits of retraining prime-aged adults by analyzing the impacts of community college schooling on displaced workers in Washington State during the 1990s. The authors also conducted a similar analysis of a small program that provided community college courses to workers displaced from their jobs during the mid-1980s in Alleghany County, (Pittsburgh) Pennsylvania. The samples were constructed by matching displaced workers' state unemployment insurance earnings records to their community college transcripts. The samples included only workers who had three or more years of job tenure when they were permanently displaced from their jobs. The Washington State sample consists of 21,000 workers displaced between 1990 and 1994 who enrolled in at least one community college course, and 64,000 displaced workers who did not take courses. The Pittsburgh sample consists of 3,200 displaced workers who took part in a county training program, and 3,500 displaced workers who did not enroll in the program. Both samples include dropouts in the samples of workers who enrolled in retraining programs. Findings of this study indicate that one year of community college training raised the hourly wage of both male and female workers by less than 2%. But earnings increased 5-6% because of increased hours worked due to training. (Contains 8 tables and 25 references.)

Trade and fisheries: Key issues for the World Trade Organization

Fisheries are common-pool resources, and many of world's fisheries are overexploited. At the same time, capture fisheries and aquaculture operations can impinge on public goods provided by marine ecosystems such as marine biodiversity and unique habitat. The common-pool and public goods dimensions of the marine environment justify regulation, but the issues frequently transcend national boundaries. Individual countries have few alternatives to protect the marine environment beyond their own jurisdictions. The international nature of marine conservation thus provides an incentive for countries to use trade policy as an indirect means to protect the marine environment. Because a large share of the available seafood is being traded, trade restrictions can potentially lead to better resource protection and better fishing practices.
Change and innovation strategies during the implementation of an open source LMS : an Australian case study

This paper analyses the change and innovation strategies that Charles Sturt University (CSU) used during the implementation of an open source learning management system (LMS) i.e. Sakai but locally called CSU Interact in 2007 and 2008. CSU was in January 2008 the first Australian University to implement an open source learning management system institution wide. This study has been strongly influenced by the writer’s doctorate research into technological innovation in higher education. The unique charateristics of implementing change and innovation in higher education are discussed as well as CSU‘s change model that comprises eight dimensions that can occur in any order and also simultaneously. This model is based on the work of Kotter and Cohen, and Synnot. Two key strategies to support change of building learning communities and sharing best practice in implementing educational technology have emerged. Some of the findings were that the change was largely driven from the bottom-up and through the writer’s role from middle-management in terms of top-down strategies. During this change and innovation process it was noticeable that the known movers and shakers engaged in the process as early adopters. As indicated in the LASO model (developed by the writer as a direct income of his PhD word), a multi-pronged approach addressing topdown and bottom-up strategies has more potential for success. Educational change and innovation and the related key strategies change management, professional development and communications needs to focus on people. Technological innovation in the context of an open learning management system have wider, external implications than the local institution given the free flow of information and intellectual property within the community. CSU needs to continue to extend the educationally focussed implementation of CSU Interact in learning and teaching to create richer experiences for the students so that educational technology truly serves the purposes of learning.
Diversity Multiplexing Tradeoff for Full-Duplex Relay Networks

Co-operative communication with relay assistance helps in enhancing the capacity of point to point links. The capacity of relay networks has been known to be upper bounded by the cut-set bound. Recently, the authors of [1] showed that it is possible to achieve the upper bound up to a constant additive gap, independent of the channel parameters. Presence of multiple relays provides multiple paths from the source to the destination. With no channel state information at the transmitter, these paths can be used to either obtain a high communication rate or a low probability of error. We can trade off one of these quantities for the other. This diversity multiplexing trade off has been studied extensively for MIMO systems. However, the trade off for full duplex Gaussian relay networks is not well understood. We shall study the diversity multiplexing trade off for multiple relay networks. This work provides a lower bound on the error probability at the destination as a function of the communication rate, assuming a finite time for communication. We see that if we choose block length corresponding to the optimal DMT for the min-cut, the probability of error is governed by one of the cuts with diversity gain less than the min-cut diversity gain. The error probability is exactly equal to the one obtained from the optimal DMT for the corresponding cut.
Biased Technical Change and Economic Growth: The Case of Korea, 1970–2013

This paper explores the pattern of technical change in the Korean economy from 1970 to 2013 and investigates its determinants. We use the Classical growth-distribution schedule to show that the labor-saving and capital-using pattern has predominated. For the rationale behind this Marx-biased technical change (“MBTC”), we focus on the relationship between technical change and real wage growth via the evolution of labor and capital productivity, and verify the historical direction of technical change against the rise and fall of the working class. Furthermore, we find that the deviation during the post-crisis period from the long-run trend of MBTC is not attributable to the vitality of new technological innovations, but rather the reflection of class dynamics over extracting productivity under weaker capital deepening. The results suggest that the recent deterioration of labor share and labor unions in Korea is closely associated with low incentive for technological progress, which contributes to prolonged stagnation.
Optical wireless cochlear implants

In the present contribution, we introduce a wireless optical communication-based system architecture which is shown to significantly improve the reliability and the spectral and power efficiency of the transcutaneous link in cochlear implants (CIs). We refer to the proposed system as optical wireless cochlear implant (OWCI). In order to provide a quantified understanding of its design parameters, we establish a theoretical framework that takes into account the channel particularities, the integration area of the internal unit, the transceivers misalignment, and the characteristics of the optical units. To this end, we derive explicit expressions for the corresponding average signal-to-noise-ratio, outage probability, ergodic spectral efficiency and capacity of the transcutaneous optical link (TOL). These expressions are subsequently used to assess the dependence of the TOL’s communication quality on the transceivers design parameters and the corresponding channels characteristics. The offered analytic results are corroborated with respective results from Monte Carlo simulations. Our findings reveal that OWCI is a particularly promising architecture that drastically increases the reliability and effectiveness of the CI TOL, whilst it requires considerably lower transmit power compared to the corresponding widely-used radio frequency (RF) solution. © 2019 Optical Society of America under the terms of the OSA Open Access Publishing Agreement
Valuations of ‘Sustainably Produced’ Labels on Beef, Tomato, and Apple Products

This study evaluates consumer perceptions of what “sustainably produced” food labels imply and estimates corresponding demand for products carrying these labels. Results suggest that the typical U.S. consumer is not willing to pay a positive premium for beef, tomatoes, or apple products labeled as “sustainably produced. ” Demand is particularly sensitive to inferences consumers make regarding what a “sustainably produced” food label implies. Suggestions for future work and implications of standardizing the definition of sustainability are provided.
Pictorial Competence in Primates: A Cognitive Correlate of Mirror Self-Recognition?

Alternative interpretation to the long-standing assertion that mirror self-recognition entails self-awareness suggests that mirror self-recognition rather refers to the ability to differentiate its own body from other objects of the environment. From this standpoint, individuals should be able to interpret the mirror reflection as a symbolic representation of the self and to map this image to an internal representation of self. The framework of this chapter is based on the assumption that the cognitive processing underlying self-recognition might be related to the capacity of processing mirror image as a symbolic representation of the real object. To support that purpose, the critical developmental and comparative literature on pictorial competence and self-recognition ability in human infants and primates are contrasted. Furthermore, relationship between mirror self-recognition and pictorial abilities are discussed based upon two experiments. We first observed the behavior of pictorially naive primates, with a realistic picture. We second assessed whether non-naïve chimpanzees, demonstrating or not self-recognition, would behave with a realistic picture. Finally, I propose a refined postulate that illustrates how the pictorial competence and self-recognition ability may co-develop. The intent of this model is to open up new perspectives for further explorations of self-recognition ability in primates. involved 55 baboons ( Papio anubis ): 26 males and 29 females (mean age 6.9 years, S.D. = 4.6 years) from the CNRS Rousset-sur-Arc Primate Center (France), 7 chimpanzees ( Pan troglodytes ): 3 males and 4 females (mean age 9.75 years, S.D. = 7.3 years) from the Wolfgang Kohler Primate Research Center of the Leipzig Zoo, and 4 gorillas ( Gorilla gorilla ): 1 male and 3 females (age 24.5 years, S.D. = 11.15 years) from the zoos of Leipzig or Nuremberg (Germany). Monkeys and apes, habitually housed in social group, were either tested in groups or isolated, depending on the specificity of their living quarters. Their participation was always voluntary. All animals were selected at purpose because they have no known exposure to videos, still pictures, or draw -ings, and were thus pictorially naive. We hypothesized that testing monkeys and apes at an equivalent level of expertise with two-dimensional stimuli would provide cues on the evolu tion of picture comprehension within the primate phylum. This research adhered to the legal requirements of the current French laws and the European directive 2010/63/EU (see Figure 2 ).
Spiking Neurons with Boltzmann-like Properties to Learn Xor

A computational model of biological neurons is used to learn the exclusive or relation. The neural model is a fatiguing leaky integrate and fire model, and spontaneous firing emerges from the hypo-fatigue. This spontaneous firing enables the system to move from direct stimulation from the environment. A form of Hebbian learning, post-synaptic weighted compensatory learning, is used to support firing in interior neurons. A range of numbers of interior neurons performs the task at above 99% precision.
Assessment of Petroleum Reservoir Recovery Factor Using Complexity Scoring and Artificial Neural Network

The Recovery factor (R.F) is an important parameter needed for assessing the commercial viability of a petroleum reservoir. This parameter is however very difficult to determine as existing models require large number of parameters that must be known accurately. This paper demonstrates the use of complexity scoring approach and artificial neural network in predicting the recovery factor of petroleum reservoirs. Various oilfields with known complexity parameters and recovery factors were considered. These complexity parameters were then scored based on carefully defined criteria. The scored parameters were then used to train a carefully designed artificial neural network (ANN) which was then validated and tested for RF prediction. Results show good prediction of RF with this approach.
Sectoral Heterogeneity in the Employment Effects of Job Creation Schemes in Germany

Summary Job creation schemes (JCS) have been one important programme of active labour market policy (ALMP) in Germany for a long time. They aim at the re-integration of hard-to-place unemployed individuals into regular employment. A thorough microeconometric evaluation of these programmes was hindered by the fact, that available survey datasets have been too small to account for a possible occurrence of effect heterogeneity. However, identifying effect heterogeneity can help to improve the design and implementation of future programmes. Hence, we use administrative data of the Federal Employment Agency, containing over 11,000 participants to analyse the employment effects of JCS on an individual level. We focus explicitly on effect heterogeneity caused by differences in the implementation of programmes, whereas we analysed these effects with respect to group-specific and regional heterogeneity in a previous paper. At first, we evaluate the effects with respect to the economic sector in which the JCS are accomplished. Second, we analyse if different types of support lead to different effects. Finally, we examine if there are varying effects which can be attributed to different implementing institutions. The results are rather discouraging and show that JCS are in general not able to improve the re-integration chances of participants into regular employment.
