Practical Privacy-Preserving Multiparty Linear Programming Based on Problem Transformation

Cryptographic solutions to privacy-preserving multiparty linear programming are slow. This makes them unsuitable for many economically important applications, such as supply chain optimization, whose size exceeds their practically feasible input range. In this paper we present a privacy-preserving transformation that allows secure outsourcing of the linear program computation in an efficient manner. We evaluate security by quantifying the leakage about the input after the transformation and present implementation results. Using this transformation, we can mostly replace the costly cryptographic operations and securely solve problems several orders of magnitude larger.
Joint Transceiver Design for Full-Duplex Cloud Radio Access Networks with SWIPT

This work studies the joint transceiver design for a full-duplex (FD) cloud radio access network (C- RAN) with simultaneous wireless information and power transfer (SWIPT). In the considered network, a number of FD remote radio heads (RRHs) receive information from uplink users (UUs), while transmitting both information and energy to a set of half-duplex (HD) downlink users (DUs) with power splitting receivers. Based on the particular problem structure, a block coordinate descent (BCD) method is proposed to minimize the total transmission power subject to both uplink-downlink quality of service (QoS) constraints and energy harvesting (EH) constraints. Although the problem has complicated constraints coupling a set of transceivers, uplink transmit power levels, and receive power splitting ratios, we prove that the proposed BCD algorithm converges to a Karush-Kuhn- Tucker (KKT) solution. Simulation results validate the effectiveness of the proposed algorithm as compared with the traditional HD scheme.
Flow-Mediated Dilatation Is Impaired by a High–Saturated Fat Diet but Not by a High-Carbohydrate Diet

Objective—It is unknown whether a low-fat diet, which may elevate triglycerides and lower high-density lipoprotein (HDL) cholesterol, harms the endothelium. Our aim was to determine whether a low-fat, high-carbohydrate (CARB) diet impaired endothelial vasodilation compared with high saturated fat (SFA), monounsaturated fat (MUFA), or polyunsaturated fat (PUFA) diets. Methods and Results—Forty healthy subjects were randomly crossed over to 4, 3-week isocaloric diets high in PUFA, MUFA, or SFA, containing at least 25 g of the relevant fat or a low-fat, CARB, high–glycemic load diet. Flow-mediated dilatation (FMD), fasting blood lipids, high sensitivity C-reactive protein, plasma intercellular, and vascular adhesion molecules plasma E- and P-selectin were measured after each intervention. SFA impaired FMD compared with all other diets (5.41±2.45% versus 10.80±3.69%; P=0.01). FMD did not change on CARB relative to MUFA or PUFA, despite 23% to 39% rises in triglyceride and 10% to 15% falls in HDL cholesterol. P-selectin was highest after SFA (121±52.7 ng/mL) versus MUFA (98±44.5 ng/mL; P=0.001) and PUFA (96±36.4 ng/mL; P=0.001). Conclusion—High SFA caused deterioration in FMD compared with high PUFA, MUFA, or CARB diets. Inflammatory responses may also be increased on this diet.
Effect of the pitch size and presence of goalkeepers on the work load of players during small-sided soccer games

Abstract Small-sided games (SSGs) are spontaneous forms of specific training where exercise intensity can be manipulated by modifying external factors. To ensure suitable usage of small-sided games in practice, we have to know which variables can influence internal responses and external loads. The aim of the present study was to determine the influence of presence of a goalkeeper and the pitch size on internal responses and the external load during five-a-side soccer games. Twenty nine junior soccer players (age: 18.11 ± 1.31 years; body mass index: 21.04 ± 2.58 kg·m-2; peak heart rate: 199.53 ± 7.51 beats·min–1) participated in the study. The heart rate, distance covered and the rate of perceived exertion were monitored. We found significantly higher average heart rates of players in 5v5 SSGs without goalkeepers than with them on a small pitch. Analysis showed significant differences in the time spent in 65-85% of the peak heart rate zone and ˂65% of the peak heart rate zone on the small pitch. Furthermore, we found significantly higher distance covered by players during five-a-side games with goalkeepers than without them played on the small pitch. Our results indicate that the pitch size is a very important variable that influences the work load of players. The inclusion of the goalkeeper decreases the work load of the player on a small pitch (28 × 20 m; 560 m2), but not on a medium or large pitch.
Relations between blood serum biochemical indicators and weight gain and fat and lean meat content of carcass in pigs

In 98 growing pigs serum biochemical indicators (T4, T3, AspAT, ALAT, total protein, urea nitrogen and total cholesterol) were determined twice, at the end of the first fattening phase and next at slaughter. Correlations were determined between serum biochemical indicators, daily gains in the two fattening stages and carcass quality characteristics. We found a number of significant changes in serum concentration of particular components during the fattening period. T4 level was lower at the end of fattening (P<0.01), no visible changes were found in T3 and urea nitrogen, whereas the remaining indicators, particularly transaminases, displayed a significant increase (P<0.01). Some of the indicators were significantly correlated with weight gain (total serum protein, urea, AspAT and ALAT) or with carcass fatness (T4, urea, cholesterol, AspAT) and carcass lean meat content (urea, AspAT). The results proved the significant effects of biochemical metabolic processes on some fattening performance traits as well as on the fat and lean meat content of carcass in pigs.
Partial Key-Hiding in RSA

This paper explores the idea of partially exposing sections of the private key in public-key cryptosystems whose security is based on the intractability of factorising large integers. It is proposed to allow significant portions of the private key to be publicly available, reducing the amount of data which must be securely hidden. The “secret” data could be XORed with an individual’s biometric reading in order to maintain a high level of security, and we suggest using iris templates for this purpose. Finally, we propose an implementation of this system for RSA, and consider the potential risks and advantages associated with such a scheme.
Structural model of the alpha phosphoglucomutase: A promising target for the treatment of mycobacterium tuberculosis

Objective: Tb is considered to be growing menaces in various countries especially Africa and South East Asia. In 2011, 8.7 million people fell ill with TB, out of which a total of about 1.4 million people died. The children being affected in large, increases the severity of Tb. It remains to be the leading cause of death of people infected with HIV. The growing multidrug resistant strains of bacteria affecting the population has increase since 2010. The search for potential targets for fighting Tb has identified different pathways for drug development against tuberculosis. One such pathway identified, an enzyme alpha phosphoglucomutase involved in bacterial polysaccharide capsule formation, important for bacterial virulence and infection. The absence of X-ray crystallographic structure of alpha phosphoglucomutase resulted in the modelling of this potential target. Methods: Homology modelling of was performed by modeller9.1, the multiple sequence alignment was carried out selecting three different relevant templates. Model evaluation was performed using Ramachandran plot and ERRAT plot, further RMSD with the template obtained using Pymol. Results: Stereochemical evaluation of protein by Ramachandran plot indicated a good quality model with 99.8% residues in the most favoured and allowed regions. The model was compared with the suitable template by superimposing the structures, RMSD was determined to be 0. 202Å, the further analysis by ERRAT program gave a score of 95.733, both indicating a good quality model. Conclusion: The various results obtained, conclude the reliability of modelled protein which can be further used for Denovo design of inhibitors against the target.
Beam-laser lifetime measurements for low-lying quartet states in Fe II.

Radiative lifetimes for seven levels of the z $^{4}\mathrm{\ifmmode^\circ\else\textdegree\fi{}}$, $^{4}$D\ifmmode^\circ\else\textdegree\fi{}, and $^{4}$F\ifmmode^\circ\else\textdegree\fi{} terms of Fe ii have been measured by using laser excitation of a beam of fast ${\mathrm{Fe}}^{+}$ ions. The ratio of the measured lifetime to that calculated from Kurucz's gf values appears to increase systematically with the energy of the levels involved.
Structure and Properties of Protective Coatings Deposited by Pulsed Cathodic Arc Evaporation in Ar, N2, and C2H4 Environments using the TiC–NiCr–Eu2O3 Cathode

Coatings were deposited by pulsed cathodic arc evaporation (PCAE) of a TiC–NiCr–Eu2O3 cathode fabricated by the powder metallurgy method. The deposition was carried out in different gas media, including Ar, N2, and C2H4. The structure, elemental, and phase compositions of coatings were studied by scanning electron microscopy (SEM), X-ray diffraction (XRD), energy-dispersive spectroscopy (EDS), Raman spectroscopy, and glow discharge optical emission spectroscopy (GDOES). Coatings were tested in terms of their hardness, elastic modulus, elastic recovery, friction coefficient, and wear and corrosion resistance. The obtained results demonstrated that the coatings deposited in Ar possessed higher hardness up to 20 GPa and an elastic recovery of 92%. Coatings produced using С2H4 showed the minimum friction coefficient (0.35 ± 0.01). The use of nitrogen as a gas medium led to the formation of coatings with the best corrosion resistance in sulfuric acid. Coatings formed in N2 had a free corrosion potential of +0.28 V and a corrosion current density of 0.012 µA/cm2.
Expression of Caytaxin Protein in Cayman Ataxia Mouse Models Correlates with Phenotype Severity

Caytaxin is a highly-conserved protein, which is encoded by the Atcay/ATCAY gene. Mutations in Atcay/ATCAY have been identified as causative of cerebellar disorders such as the rare hereditary disease Cayman ataxia in humans, generalized dystonia in the dystonic (dt) rat, and marked motor defects in three ataxic mouse lines. While several lines of evidence suggest that Caytaxin plays a critical role in maintaining nervous system processes, the physiological function of Caytaxin has not been fully characterized. In the study presented here, we generated novel specific monoclonal antibodies against full-length Caytaxin to examine endogenous Caytaxin expression in wild type and Atcay mutant mouse lines. Caytaxin protein is absent from brain tissues in the two severely ataxic Atcayjit (jittery) and Atcayswd (sidewinder) mutant lines, and markedly decreased in the mildly ataxic/dystonic Atcayji-hes (hesitant) line, indicating a correlation between Caytaxin expression and disease severity. As the expression of wild type human Caytaxin in mutant sidewinder and jittery mice rescues the ataxic phenotype, Caytaxin’s physiological function appears to be conserved between the human and mouse orthologs. Across multiple species and in several neuronal cell lines Caytaxin is expressed as several protein isoforms, the two largest of which are caused by the usage of conserved methionine translation start sites. The work described in this manuscript presents an initial characterization of the Caytaxin protein and its expression in wild type and several mutant mouse models. Utilizing these animal models of human Cayman Ataxia will now allow an in-depth analysis to elucidate Caytaxin’s role in maintaining normal neuronal function.
Evaluation Traditions in Denmark

Evaluation research developed slowly in Denmark, partly due to special political conditions in the development of the Danish welfare state. In the last 10 years evaluation has been growing rapidly, especially in the area of public services. This article presents four major traditions in Danish evaluation research today; survey-based evaluations, theory-developing evaluations, action research-based evaluations and internal evaluations. The picture of Danish evaluation research is still rather dominated by survey- based evaluations relying on otherwise much criticized positivistic quantitative methods and without the use of theory in evaluations. Even if other traditions exist the international discussions of theory and methods in evaluation research have not yet found their way into Danish evaluation discussions to any substantial degree. The positive political interest in Denmark in the use of evaluations—and especially the growth in internal evaluations—accentuates the problem of evaluation research being able to overcome its link with positivistic methodologies and subsequently integrate newer traditions in social science theory and methodology in order to produce useful knowledge.
Cultivable endophytic bacteria from leaf bases of Agave tequilana and their role as plant growth promoters

Agave tequilana Weber var. ‘Azul’ is grown for the production of tequila, inulin and syrup. Diverse bacteria inhabit plant tissues and play a crucial role for plant health and growth. In this study culturable endophytic bacteria were extracted from leaf bases of 100 healthy Agave tequilana plants. In plant tissue bacteria occurred at mean population densities of 3 million CFU/g of fresh plant tissue. Three hundred endophytic strains were isolated and 16s rDNA sequences grouped the bacteria into eight different taxa that shared high homology with other known sequences. Bacterial endophytes were identified as Acinectobacter sp. , A. baumanii, A. bereziniae, Cronobacter sakazakii, Enterobacter hormaechei, Bacillus sp. Klebsiella oxytoca, Pseudomonas sp. , Enterococcus casseliflavus, Leuconostoc mesenteroides subsp. mesenteroides and Gluconobacter oxydans. Isolates were confirmed to be plant growth promoting bacteria (PGPB) by their capacities for nitrogen fixation, auxin production, phosphate solubilization, or antagonism against Fusarium oxysporum AC132. E. casseliflavus JM47 and K. oxytoca JM26 secreted the highest concentrations of IAA. The endophyte Acinectobacter sp. JM58 exhibited the maximum values for nitrogen fixation and phosphate solubilization index (PSI). Inhibition of fungi was found in Pseudomonas sp. JM9p and K. oxytoca JM26. Bacterial endophytes show promise for use as bio-inoculants for agave cultivation. Use of endophytes to enhance cultivation of agave may be particularly important for plants produced by micropropagation techniques, where native endophytes may have been lost.
Use of inertial sensors to support video tracking

One of the biggest obstacles to building effective augmented reality (AR) systems is the lack of accurate sensors that report the location of the user in an environment during arbitrary long periods of movements. In this paper, we present an effective hybrid approach that integrates inertial and vision‐based technologies. This work is motivated by the need to explicitly take into account the relatively poor accuracy of inertial sensors and thus to define an efficient strategy for the collaborative process between the vision‐based system and the sensor. The contributions of this papers are threefold: (i) our collaborative strategy fully integrates the sensitivity error of the sensor: the sensitivity is practically studied and is propagated into the collaborative process, especially in the matching stage (ii) we propose an original online synchronization process between the vision‐based system and the sensor. This process allows us to use the sensor only when needed. (iii) an effective AR system using this hybrid tracking is demonstrated through an e‐commerce application in unprepared environments.

Mediators of the Relation Between Sexual Victimization and Distress: Comparison to Bereavement

Objective: The purposes of this research were (a) to examine relationship quality and neuroticism as mediators of the relation between past sexual victimization and current distress in 2 samples of college students and (b) to examine the specificity of the mediated effects by assessing whether these variables also mediated the relation between the most common potentially traumatic event in both samples (past bereavement) and current distress. This study improved on prior research by using longitudinal data, assessing multiple mediators, assessing specificity of mediated effects, and replicating results across 2 samples. Method: Participants in both studies were undergraduate students in psychology courses (Ns = 1,528 and 1,084, respectively). In both studies, sexual victimization, bereavement and the 2 mediators (relationship quality and neuroticism) were assessed at baseline, and distress was assessed at baseline and 2 months later using standard measures. Results: Structural equation modeling was used to assess the indirect (mediated) effects of sexual victimization and bereavement on later distress through relationship quality and neuroticism, controlling for baseline distress. In Study 1, the indirect effects of sexual victimization on distress through relationship quality and neuroticism were both significant. In Study 2, only the indirect effects through neuroticism were significant. None of the indirect effects were significant for bereavement, suggesting that the mediators were specific to sexual victimization. Conclusions: Neuroticism was a consistent mediator of the relation between lifetime sexual victimization and current distress, suggesting that it may be an important target of intervention for those with a history of sexual victimization.
Impact of One HF-rTMS Session on Fine Motor Function in Right-Handed Healthy Female Subjects: A Comparison of Stimulation over the Left versus the Right Dorsolateral Prefrontal Cortex

Background: Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive tool to investigate neural conduction in motor processes. Most rTMS research has been conducted by targeting the primary motor cortex. Several studies have also found increased psychomotor speed after rTMS of the dorsolateral prefrontal cortex (DLPFC). However, these studies were mainly performed in psychiatric patients, only targeting the left DLPFC, and often without sham control. Moreover, psychomotor speed is mostly measured based on tasks that also require higher executive functions. Methods: Here, we examined the lateralized effect of one sham-controlled high-frequency rTMS session applied to the left or right DLPFC on fine motor function in 36 healthy right-handed females, using the Fitts’ paradigm. Results: We found a significant improvement in psychomotor speed only after actively stimulating the right DLPFC. Conclusion: Our results support the assumption of a right prefrontal neural network implicated in visuomotor behavior and performance processes, and that the improvement in psychomotor speed is not a secondary effect of decreased mood.
Qualitative Analysis of College Students' Ideas about the Earth: Interviews and Open-Ended Questionnaires

Student conceptual understanding and conceptual change is an active area of research in many science disciplines. In the geosciences, alternative conceptions held by students, particularly college students, are not well documented or understood. To further this body of research, students enrolled in introductory science courses at four institutions completed 265 open-ended questionnaires and participated in 105 interviews. Data were collected at a small private university, two large state schools, and one small public liberal arts college. Students were probed on a variety of topics related to the Earth's crust and interior, as well as geologic time. Analysis of questionnaire and interview responses indicates that students hold a number of non-scientific ideas about the Earth. Additionally, students apply a range of ontological categories to geologic phenomena, with significant implications for teaching geosciences from a systems perspective.
Performance degradation due to code tracking errors on a RAKE spread-spectrum receiver in the presence of unresolvable multipath

The effects of multipath and tracking error on a RAKE receiver are analyzed. It is shown that, in the presence of unresolvable multipath, the RAKE receiver, formed by combining the same samples that are used for tracking, is less sensitive to tracking errors, and that there is a wide range of tracking errors for which such a receiver outperforms the conventional receiver. Also, the effects of how interchip interference degrades the performance of the proposed receiver are examined.
Strongly interacting dynamics beyond the standard model on a space–time lattice

Strong theoretical arguments suggest that the Higgs sector of the standard model of electroweak interactions is an effective low-energy theory, with a more fundamental theory expected to emerge at an energy scale of the order of a teraelectronvolt. One possibility is that the more fundamental theory is strongly interacting and the Higgs sector is given by the low-energy dynamics of the underlying theory. I review recent works aimed at determining observable quantities by numerical simulations of strongly interacting theories proposed in the literature to explain the electroweak symmetry-breaking mechanism. These investigations are based on Monte Carlo simulations of the theory formulated on a space–time lattice. I focus on the so-called minimal walking technicolour scenario, an SU(2) gauge theory with two flavours of fermions in the adjoint representation. The emerging picture is that this theory has an infrared fixed point that dominates the large-distance physics. I shall discuss the first numerical determinations of quantities of phenomenological interest for this theory and analyse future directions of quantitative studies of strongly interacting theories beyond the standard model with lattice techniques. In particular, I report on a finite size scaling determination of the chiral condensate anomalous dimension γ, for which 0.05≤γ≤0.25.
Probabilistic Prediction of Privacy Risks in User Search Histories

This paper proposes a new model of user-centric, global, probabilistic privacy, geared for today's challenges of helping users to manage their privacy-sensitive information across a wide variety of social networks, online communities, QA forums, and search histories. Our approach anticipates an adversary that harnesses global background knowledge and rich statistics in order to make educated guesses, that is, probabilistic inferences at sensitive data. We aim for a tool that simulates such a powerful adversary, predicts privacy risks, and guides the user. In this paper, our framework is specialized for the case of Internet search histories. We present preliminary experiments that demonstrate how estimators of global correlations among sensitive and non-sensitive key-value items can be fed into a probabilistic graphical model in order to compute meaningful measures of privacy risk.
Low power pipelining of linear systems: A common operand centric approach

In this paper, we propose a systematic pipelining method for a linear system to minimize power and maximize throughput, given a constraint on the number of pipeline stages and a set of resource constraints. The method first retimes operations such that as many operations as possible take common operands as their inputs, and then performs the operand sharing based on the list scheduling. Experimental results show that the proposed approach reduces the power consumption of the functional units by up to more than 20%, compared to the state-of-the-art pipelining and operand sharing techniques.
