Find U: Privacy-Preserving Distributed Profile Matching in Secure Multi-party Computation (SMC) for Preventing Malicious Attacks

Making new connections according to personal preferences is a crucial service in mobile social networking, where the initiating user can find matching users within physical proximity of him/her. In existing systems for such services, usually all the users directly publish their complete profiles for others to search. However, in many applications, the users’ personal profiles may contain sensitive information that they do not want to make public. In this paper, we propose Find U, the first privacy-preserving personal profile matching schemes for mobile social networks. In Find U, an initiating user can find from a group of users the one whose profile best matches with his/her; to limit the risk of privacy exposure, only necessary and minimal information about the private attributes of the participating users is exchanged. Matching user profiles using their physical proximity via mobile social networking is a critical thing. We propose Find U, the concept used to limit the privacy levels and also to find the best matching profiles. To realize the user privacy levels here we are using secure multiparty computation (SMC) techniques. We also propose protocols such as PSI, PCSI to prove their security proofs. We evaluate the efficiency of the protocols by adopting the total run time and energy consumption.
Aggregating Static and Dynamic Methodologies For PHP Application Security Assessment

The state-of-the-art tools for bug discovery in languages used for web-application development, such as PHP, suffer from a relatively high falsepositive rate and low coverage of real errors; this is caused mainly by non-precise modeling of dynamic features of such languages and path-insensitivity of the tools. In this project, we will demonstrate Lacunae of the current tools and implement a novel approach to address these issues. We will show how our technique handles some of the situations where other tools fail and illustrate it on examples.
HPLC ANALYSIS OF AMINOACIDS IN THE MERCURY AND CADMIUM TREATED GILL, LIVER AND MUSCLE IN Clarias batrachus

High performance liquid chromatography (HPLC) based separation of individual amino acids was quite revealing and promising field. It has provided the present study with necessary information on amino acid metabolism in the target tissues of the experimental fish Clarias batrachus and also in their relative assimilation, storage and excretion during stress induced response with treated heavy metals like mercury (Hg) and cadmium (Cd). This induction was found to be both as tissue and time specific as it was clearly observed in the morphological changes in gill, liver and muscles. Such differential expression was a great monitor to understand the physiological and cellular adaption's of the fish. The LC50 values were observed at 1.5ppm and 8.0ppm with the treated heavy metals of mercury and cadmium in the fish C.batrachus . HPLC studies revealed changes in the intensity and ranges of amide I, II and III bands in control, mercury and cadmium treated tissues. Amide II band was only the characteristic feature of the treated tissues and it was absent in the control tissues. Amide III band was notably present in the liver tissue exclusively. The presence of these amide band results gave a new direction to the studies on binding site determination of heavy metals like mercury and cadmium.

Does Titling Matter? Evidence from Housing Markets in India

In this paper, we exploit the plausibly exogenous random relocation of slum dwellers in Pune, India to evaluate whether the provision of a formal title is capitalized into property values. Using propensity score matching methods, which address important sources of bias that are present in conventional Ordinary Least Squares (OLS) hedonic methods, we find no effect of titling. Our results suggest that slum improvements may be sufficient to enhance informal tenure rights and that formalizing those rights with a title has little additional impact. An analysis of heterogeneous treatment effects from titling confirms this conclusion, providing preliminary evidence when titling may complement or substitute for other slum interventions.
Optimization of Metal Forming Processes for Improving Final Mechanical Strength

The fundamental mechanical assumptions and the basic principles of 3-dimensional FE discretization are briefly summarized. Several important numerical developments for efficient and accurate computation of large plastic deformation are discussed. Material behavior must be known precisely: material parameters of the constitutive law, thermal law and friction law must be determined by experimental tests and identification procedures by inverse modeling. Is it also necessary to avoid the possible onset of defects, such as crack opening, by introducing damage modeling in the cost function. A parameter sensitivity analysis is utilized in order to select the most important factors: shape of the preform, tools geometry, etc. The practical optimization is carried out by a genetic algorithm technique or by a surface response method. Moreover, for assessing the fatigue behavior, a more local approach is necessary in order to take into account material evolution at the micro scale.
Correlation between biliary bacteriology and types of gallstones in uncomplicated symptomatic cholelithiasis

The aim of this study was to identify the microflora in the gallbladder of patients undergoing cholecystectomy for different types of gallstones and the antibiotic susceptibility pattern of the isolates. Between January 2005 and December 2008, 136 samples of bile [cholesterol stones (CS)] and 175 pigment stones (PS) were collected from 213 women and 98 men, who were between 18-95 years (median age: 52.5±12.0) by laparoscopic or open cholecystectomy at the University Surgical Unit Duzce in Turkey. The bile samples were aerobically cultured to assess microflora and their antibiotic susceptibility. 210 (54%) of the 311 patients with gallstones had bacterial isolates; 78 isolates (37.2%) were from cholesterol stone-containing bile and 132 isolates (62.8%) from pigment stone-containing bile (P<0.01). The overall bacterial isolates from bile samples revealed Escherichia coli (E. coli) predominantly, followed by Pseudomonas aeruginosa (P. aeruginosa) and Enterococcus spp. In one sample, we found Candida lusitaniae (C. lusitaniae). None of the Gram negative strains were resistant to antibiotics but Gram positive strains were highly resistant to penicillins (100%). Looking at the microflora of the gallbladder and the susceptibility pattern of our isolates, we would suggest that antibiotic prophylaxis recommended for laparoscopic or open cholecystectomy for gallstones be reviewed and the role of bacteribilia in the surgical management of cholelithiasis requires further study. Key words: Microflora, bile culture, gallstones, cholecystectomy.
STATCOM Optimal Allocation in Transmission Grids Considering Contingency Analysis in OPF Using BF-PSO Algorithm

In this paper, a combinational optimization algorithm is introduced to obtain the best size and location of Static Compensator (STATCOM) in power systems. Its main contribution is considering contingency analysis where lines outages may lead to infeasible solutions especially at peak loads and it commonly can be vanished by loadshedding. The objective of the proposed algorithm is firstly to prevent infeasible power flow solutions without undesired load-shedding, which is critical in contingency analysis; and secondly to mitigate overall power losses and costs. Moreover, active and reactive powers generation costs are considered in the proposed objective function. Since there are various constraints such as lines outages number, cost and their duration that must be taken to account, Bacterial Foraging oriented by Particle Swarm Optimization (BF-PSO) algorithm combined with Optimal Power Flow (OPF) is used to solve and overcome the complexity of this combinational nonlinear problem. In order to validate the accuracy of the proposed method, two test systems, including IEEE 30 bus standard system and Azarbaijan regional power system of Iran, are applied in simulation studies. All obtained optimization results show the effectiveness of the suggested combinational method in loss and cost reduction and preventing load-shedding.
Atomic displacement in the CrMnFeCoNi high-entropy alloy – A scaling factor to predict solid solution strengthening

Although metals strengthened by alloying have been used for millennia, models to quantify solid solution strengthening (SSS) were first proposed scarcely seventy years ago. Early models could predict the strengths of only simple alloys such as dilute binaries and not those of compositionally complex alloys because of the difficulty of calculating dislocation-solute interaction energies. Recently, models and theories of SSS have been proposed to tackle complex high-entropy alloys (HEAs). Here we show that the strength at 0 K of a prototypical HEA, CrMnFeCoNi, can be scaled and predicted using the root-mean-square atomic displacement, which can be deduced from X-ray diffraction and first-principles calculations as the isotropic atomic displacement parameter, that is, the average displacements of the constituent atoms from regular lattice positions. We show that our approach can be applied successfully to rationalize SSS in FeCoNi, MnFeCoNi, MnCoNi, MnFeNi, CrCoNi, CrFeCoNi, and CrMnCoNi, which are all medium-entropy subsets of the CrMnFeCoNi HEA.
Dynamics and mass balance of El Chichón crater lake, Mexico

El balance de masa en el lago del crater del Chichón es controlado por Ia precipitación y Ia evaporación, asi como por la infiltración en el fondo del lago. La fuente principal no meteórica de agua y Cl de este lago es un manantial en ebullición (Soap Pool) que descarga aguas salobres y neutras dentro del crater con una taza de flujo que varia entre los 0 y 30 kg/s. Las variaciones temporales en el volumen del lago fueron determinadas aproximadamente mediante fotografias digitalizadas del lago y una relación empirica entre la profundidad del lago y su superficie, que se obtuvo con cuatro levantamientos batimétricos. La mejor correlación entre los cambios observados en el volumen del lago, el contenido de Cl y la taza de flujo medido en el manantial Soap Pool se logró con un modelo de caja para el balance de Cl. Se propone un modelo de lago "enterrado" basado en Ia tendencia en el contenido de Cl en el agua de Soap Pool.doi: sin doi
Aus dem Institut für Veterinär-Physiologie des Fachbereiches Veterinärmedizin der Freien Universität Berlin Identification of Metabolic Prognostic Markers in Liver Diseases After Carbon Tetrachloride Intoxication Inaugural-Dissertation zur Erlangung des Grades eines Doktors der Veterinärmedizin

Currently, the golden standards of liver disease diagnosis are based on histological assessments of biopsies and some clinical parameters. The use of liver biopsies, however, is not without cost or risk (bleeding, perforation, death). Furthermore, liver biopsies can be subjected to sampling and interand intra-observer variabilities. Moreover, most of clinical parameters are not liver specific and might not be sensitive to predict minimal alterations and disease progression. Therefore, we aim to identify minimal invasive biomarker(s) that can be used to differentiate stages of liver disease. Metabolomics profiling of healthy and CCl4-induced fibrotic mice using an updated version of Nuclear Magnetic Resonance (MAS-H-NMR) was performed. We have investigated the fingerprints of fibrosis progression by biochemical, histopathological, and metabolomics as well as gene expression analysis in a time-resolved experiment in both models. Biochemical parameters like e.g. ALT and AST were increased during disease progression upon CCl4 injection. This alteration was correlated with the accumulation of extracellular matrix (ECM) as indicated by picro-sirius red and hematoxylin and eosin staining. Furthermore, blood plasma-based metabolic profiling revealed that several metabolites namely, acetate, ethanol, glucose and lactate significantly reflect the disease as indicated by AUC values (1.00) compared to healthy mice. Some metabolites e.g. betaine, phenylalanine, citrate, glutamine, alanine, pyruvate, creatinine and O-phosphocholine could also be used to predict the disease stages, however, the AUC values was in the range between 0.74 and 0.963 and differed according to the disease stage. Formate, valine and tyrosine were shown to be identified as poorly predictors where the AUC values of which were in a range between 0.52 and 0.67. A further clinical validation of the very good predictors is ongoing.
Mediators of renal injury in membranous nephropathy

Membranous nephropathy (MN) is a common glomerular disease characterized by podocyte injury and proteinuria, often in the nephrotic range. Heymann nephritis (HN), a rat model of MN, has contributed to elucidation of the under- lying pathogenic mechanisms which involve in situ formation of subepithelial immune deposits of antibody reactive with podocyte antigen(s) that produce glomerular injury by damaging and/or activating podocytes through comple- ment-dependent processes. Disorganization of the cytoskeleton with subse- quent redistribution of components of the slit diaphragm and loss of the glomerular charge barrier induces proteinuria in MN. C5b-9 in sublytic quanti- ties stimulates podocytes to produce proteases, oxidants, prostanoids, extra- cellular matrix components, and cytokines. Alterations of the cytoskeleton induced by C5b-9 also lead podocyte depletion through apoptosis and detach- ment of viable podocytes. Furthermore, complement components in proteinuric urine induce proximal tubular epithelial cell injury and mediate progressive tubu- lointerstitial injury in MN.
An anti-aliasing filter based on continuous-time delta-sigma modulation

An anti-aliasing filter that incorporates a sampler is proposed. Its architecture is inspired by the anti-aliasing filtering property of continuous-time (CT) delta-sigma (DS) modulators. However, contrary to CT DS modulators, the proposed sampling anti-aliasing filter is not sensitive to clock jitter. Furthermore, its key characteristics include: 1) high suppression of aliases - for example, compared to a Butterworth filter of the same order - owing to its notches at multiples of the sampling frequency; 2) high-pass shaping of sampling errors, similar to the shaping of quantization noise in DS modulators; and 3) its alias suppression is preserved over a broad range of sampling frequencies, thereby enabling its use as a general-purpose intellectual property (IP) block. Thus, the proposed sampling anti-aliasing filter is particularly attractive at the input of noise-shaping analog-to-digital converters (ADCs), such as discrete-time (DT) DS ADCs. Its performance advantages are derived theoretically and confirmed through simulations. %%%%Un filtre anticrenelage qui incorpore un echantillonneur est propose ci-apres. Son architecture s'inspire des proprietes d'anticrenelage des modulateurs delta-sigma (DS) en temps continu (TS). Neanmoins, contrairement aux modulateurs DS TC, le filtre propose n'est pas victime de la sensibilite au bruit d'horloge. De plus, ce filtre anticrenelage possede entre autres les qualites suivantes: 1) Reduction elevee des creneaux non desires - en comparaison par exemple aux crenaux d'un filter Butterworth du meme ordre - ceci grâce a la presence de points rejet dans le reponse du filtre aux multiples de la frequence d'echantillonnage; 2) Transformation passe-haut des erreurs d'echantillonnage, de facon similaire a la transfomation du bruit de quantification dans les modulateurs DS; 3) Preservation de la suppression des creneaux a travers une bande large de frequences d'echantillonnage; ce qui en permet l'usage banalise sous forme de block de propriete intellectuelle (PI). Ainsi, le filtre d'echantillonnage anticrenelage propose ci-apres est particulierement adequat a l'entree de la transformation de bruit d'un convertisseur analogue-numerique (CAN) comme les CAN a temps discrets. La performance de ce filtre est derivee de maniere theorique et confirmee par des simulations.

Effects of aortic valve diseases on pressure profiles in selected locations of the human arterial system

Abstract Aortic valve diseases such as aortic stenosis and aortic regurgitation, are the most frequent valvular heart diseases. The lesions in the valves affect circulation in the whole arterial system. We study the effects with the use of a 1-D model in which an arterial segment transmits a single mode of pulse waves. The appropriate reflection coefficient and the form of the stroke pressure are devised to simulate the function of the healthy and morbid aortic valve. The time dependence of the arterial pressure is predicted at the most important locations of the arterial tree. A remarkable result is that little variations of the reflection coefficient of the vale due to the modelled diseases cause significant changes of the pressure profiles, especially at the ascending aorta, the left brachial artery and in the anterior communicating artery.
Transparency and Product Differentiation with Competing Vertical Hierarchies

We revisit the choice of product differentiation by competing firms in the Hotelling model, under the assumption that firms are vertically separated, and that retailers choose products’ characteristics. We show that retailers with private information about their marginal costs choose to produce less differentiated products than retailers with no private information, in order to increase their information rents. Hence, information asymmetry increases social welfare because it induces firms to sell products that appeal to a larger number of consumers. The socially optimal level of transparency between manufacturers and retailers depends on the weight assigned to consumers’ surplus and trades of two effects: higher transparency reduces price distortion but induces retailers to produce excessively similar products.
Ethanol Modulates Glutamatergic Transmission and NMDAR-Mediated Synaptic Plasticity in the Agranular Insular Cortex

The agranular insular cortex (AIC) has recently been investigated by the alcohol field because of its connectivity to and modulatory control over limbic and brainstem regions implicated in alcohol use disorder (AUD), and because it has shown involvement in animal models of alcohol drinking. Despite evidence of AIC involvement in AUD, there has not yet been an examination of whether ethanol modulates glutamatergic and γ-amino-butyric acid (GABA)ergic synaptic transmission and plasticity in the AIC. Characterizing how the synaptic transmission and plasticity states of AIC cortical processing neurons are modulated by acute ethanol will likely reveal the molecular targets by which chronic ethanol alters AIC function as alcohol drinking transitions from controlled to problematic. Therefore, we collected brain slices from ethanol-naïve adult male mice, obtained whole-cell recording configuration in layer 2/3 AIC pyramidal neurons, and bath-applied ethanol at pharmacologically relevant concentrations during electrophysiological assays of glutamatergic and GABAergic synaptic transmission and plasticity. We found that ethanol inhibited electrically evoked N-methyl-D-aspartate receptor (NMDAR)-mediated excitatory post-synaptic currents (EPSCs) in a concentration-related fashion, and had little effect on evoked α-amino-3-hydrox-5-methylisoxazole-4-propionic acid-type receptor (AMPAR)-mediated EPSCs. Ethanol had no effect on spontaneous excitatory post-synaptic currents (sEPSCs) or inhibitory GABAAR-mediated post-synaptic currents (sIPSCs). We found that synaptic conditioning (low-frequency stimulation for 15 min at 1 Hz) induced a form of long-term depression (LTD) of evoked AMPAR-mediated EPSCs. The ability to induce LTD was inhibited by a non-selective NMDAR antagonist (DL-2-amino-5-phosphonovaleric acid), and also by acute, intoxicating concentrations of ethanol. Taken together these data suggest that the glutamate, but not GABA system in the AIC is uniquely sensitive to ethanol, and that in particular NMDAR-mediated processes in the AIC may be disrupted by pharmacologically relevant concentrations of ethanol.
A Wide and Deep Exploration of Radio Galaxies with Subaru HSC (WERGS). I. The Optical Counterparts of FIRST Radio Sources

We report the result of optical identifications of FIRST radio sources with the Hyper Suprime-Cam Subaru Strategic Program survey (HSC-SSP). The positional cross-match within 1″ between the FIRST and HSC-SSP catalogs (i ≲ 26) produced more than 3600 optical counterparts in the 156 deg2 of the HSC-SSP field. The matched counterparts account for more than 50% of the FIRST sources in the search field, which substantially exceed previously reported fractions of SDSS counterparts (i ≲ 22) of ∼30%. Among the matched sample, 9% are optically unresolved sources such as radio-loud quasars. The optically faint (i > 21) radio galaxies (RGs) show that the fitting linear function of the 1.4 GHz source counts has a slope that is flatter than that of the bright RGs, while optically faint radio quasars show a slope steeper than that of bright radio quasars. The optically faint RGs show a flat slope in the i-band number counts down to 24 mag, implying either less massive or distant radio-active galactic nuclei (AGNs) beyond 24 mag. The photometric redshift and the comparison of colors with the galaxy models show that most of the matched RGs are distributed at redshifts from 0 to 1.5. The optically faint sample includes the high radio-loudness sources that are not seen in the optically bright sample. Such sources are located at redshift z > 1. This study gives ∼1500 radio AGNs lying at the optically faint end and high-redshift regime not probed by previous searches.
