In this paper we propose a primal-dual algorithm for the solution of inequality constrained optimization problems. The distinguishing feature of the proposed algorithm is that of exploiting as much as possible the local non-convexity of the problem to the aim of producing a sequence of points converging to second order stationary points. In the unconstrained case this task is accomplished by computing a suitable negative curvature direction of the objective function. In the constrained case it is possible to gain analogous information by exploiting the non-convexity of a particular exact merit function. The algorithm hinges on the idea of comparing, at every iteration, the relative eﬀects of two directions and then selecting the more promising one. The ﬁrst direction conveys ﬁrst order information on the problem and can be used to deﬁne a sequence of points converging toward a KKT pair of the problem. Whereas, the second direction conveys information on the local non-convexity of the problem and can be used to drive the algorithm away from regions of non-convexity. We propose a proper selection rule for these two directions which, under suitable assumptions, is able to generate a sequence of points that is globally convergent to KKT pairs that satisfy the second order necessary optimality conditions, possibly with superlinear convergence rate.
The Influence of Leadership on Employee Job Performance among Royal Malaysian Police in Klang Valley

The purpose of this paper is to examine the leadership influence on employee job performance, in this case, in the Royal Malaysian Police in Klang Valley in Malaysia. Various studies tried to examine leadership style and its influence on employee performance, job performance, firm performance, and commitment. The results were mixed, some are positive and some are negative. In the past, most of the research has taken various leadership styles that are cited under different leadership theories. This study has selected leadership styles such as supportive, participative, servant, transactional, and transformational leadership styles as independent variables that are assumed to have a direct influence on employee job performance, which is the dependent variable. A survey self-rating scale questionnaire was developed using past literature to examine leadership styles and employee performance. A sample of 196 respondents was recruited using a simple sampling technique. The collected data were recorded and analyzed using SPSS 22.0. The finding shows that only all leadership styles positively and significantly influence employee performance in the workplace.

In vitro dentin barrier cytotoxicity testing of some dental restorative materials

Objectives: To investigate the cytotoxicity of four dental restorative materials in three-dimensional (3D) L929 cell cultures using a dentin barrier test. Methods: The cytotoxicities of light-cured glass ionomer cement (Vitrebond), total-etching adhesive (GLUMA Bond5), and two self-etching adhesives (GLUMA Self Etch and Single Bond Universal) were evaluated. The permeabilities of human dentin disks with thicknesses of 300, 500, and 1000 mm were standardized using a hydraulic device. Test materials and controls were applied to the occlusal side of human dentin disks. The 3D-cell scaffolds were placed beneath the dentin disks. After a 24-h contact with the dentin barrier test device, cell viabilities were measured by performing MTT assays. Statistical analysis was performed using the Mann–Whitney U test. Results: The mean (SD) permeabilities of the 300-mm, 500-mm, and 1000-mm dentin disks were 0.626 (0.214), 0.219 (0.0387) and 0.089 (0.028) ml min 1 cm 2 cm H2O . Vitrebond was severely cytotoxic, reducing the cell viability to 10% (300-mm disk), 17% (500 mm), and 18% (1000 mm). GLUMA Bond5 reduced the cell viability to 40% (300 mm), 83% (500 mm), and 86% (1000 mm), showing moderate cytotoxicity (300-mm) and non-cytotoxicity (500-mm and 1000-mm). Single Bond Universal and GLUMA Self Etch did not significantly reduce cell viability, regardless of the dentin thicknesses, which characterized them as non-cytotoxic. Conclusions: Cytotoxicity varied with the materials tested and the thicknesses of the dentin disks. Clinical significance: The tested cytotoxicity of materials applied on 300-, 500-, and 1000-mm dentin disks indicates that the clinical use of the test materials (excepting self-etching adhesives) in deep cavities poses a potential risk of damage to the pulp tissues to an extent, depending on the thickness of the
Microbial functional signature in the atmospheric boundary layer

Abstract. Microorganisms are ubiquitous in the atmosphere, and some airborne microbial cells were shown to be particularly resistant to atmospheric physical and chemical conditions (e.g., ultraviolet – UV – radiation, desiccation and the presence of radicals). In addition to surviving, some cultivable microorganisms of airborne origin were shown to be able to grow on atmospheric chemicals in laboratory experiments. Metagenomic investigations have been used to identify specific signatures of microbial functional potential in different ecosystems. We conducted a comparative metagenomic study on the overall microbial functional potential and specific metabolic and stress-related microbial functions of atmospheric microorganisms in order to determine whether airborne microbial communities possess an atmosphere-specific functional potential signature as compared to other ecosystems (i.e., soil, sediment, snow, feces, surface seawater etc.). In the absence of a specific atmospheric signature, the atmospheric samples collected at nine sites around the world were similar to their underlying ecosystems. In addition, atmospheric samples were characterized by a relatively high proportion of fungi. The higher proportion of sequences annotated as genes involved in stress-related functions (i.e., functions related to the response to desiccation, UV radiation, oxidative stress etc.) resulted in part from the high concentrations of fungi that might resist and survive atmospheric physical stress better than bacteria.
Isolation of a phosphate solubilizing bacterial strain bacillus Tequilensis mcc 3872 from the rice field of burdwan district and characterization of its plant growth promoting traits

Excessive use of phosphatic chemical fertilizers hampers agricultural productivity. Plant absorb few amount of applied phosphate-based chemical fertilizer, rest amount is converted into insoluble complexes and stored in the soil which plants are unable to take. This has led to search for an eco-friendly and economically reasonable option for developing crop production. Phosphate solubilizing bacteria (PSB), capable of solubilize insoluble forms of phosphate into plant-utilizable soluble forms. Nine bacterial strains, possess phosphate solubilizing activity were isolated from the rice field of Burdwan and their phosphate solubilizing activity as well as other plant growth promoting traits were determined. Among them, CP6 strain, identified as Bacillus tequilensis based on 16S rDNA sequencing and phenotypic characterization, selected as best-performing strain. The cell density and Phosphate solubilizing ability of CP6 was also checked with time and in different pH to ensure CP6 strain can be introduced as a potent phosphate Biofertilizer.
A Research Paper on Hybrid Intrusion Detection System

Absrtact-An intrusion detection system (IDS) is a device or software application that monitors network or system activities for malicious activities or policy violations and produces reports to a Management Station. Some systems may attempt to stop an intrusion attempt but this is neither required nor expected of a monitoring system. Intrusion detection and prevention systems (IDPS) are primarily focused on identifying possible incidents, logging information about them, and reporting attempts. In addition, organizations use IDPSes for other purposes, such as identifying problems with security policies, documenting existing threats and deterring individuals from violating security policies. IDPSes have become a necessary addition to the security infrastructure of nearly every organization. Different methods can be used to detect intrusions which make a number of assumptions that are specific only to the particular method. Hence, in addition to the definition of the security policy and the access patterns which are used in the learning phase of the detector, the attack detection capability of an intrusion detection system also depends upon the assumptions made by individual methods for intrusion detection. The purpose of an intrusion detection system is to detect attacks. However, it is equally important to detect attacks at an early stage in order to minimize their impact. I have used Dataset and Classifier to refine Intruders in Networks.
Detecting and Eliminating Rogue Access Points in IEEE-802.11 WLAN Based on Agents Terminology and Skew Intervals: A Proposal

-The existence of rough access points in the network is now days becoming very serious security threat for networks line WLAN. The presence of such network threats always resulted into the important information leakage or damage. Previously already many tools are developed by different research groups, however they are coming with some limitations which we have to discuss and address in this research proposal. Here the agent based approach is present not only to detect the rough access points but also their elimination from the wireless networks efficiently and with minimum cost involvement. The master agent and slave agents are generated automatically, which are acts as major components for providing the security to wireless networks. These agents are continuously doing the process of networks scanning to capture the rough access points and eliminate them. This scanning is scheduled based on clock skews which are playing important role. This Methodology has the following outstanding properties: (1) it doesn’t require any specialized hardware; (2) the proposed algorithm detects and completely eliminates the UAPs from network; (3) it provides a cost-effective solution; (4) due to multiple master agents possibility of network congestion or delays is reduced. The proposed technique can block UAPs as well as remove them from the networks both in form of Unauthorized APs.
EFFECT OF IRON OXIDE ON TRIBOLOGICAL BEHAVIOUR OF AL- SI ALLOY – IRON OXIDE COMPOSITES-TAGUCHI APPROACH

This study investigates the influence of factors such as weight percentage of iron oxide, applied load and sliding velocity on the wear loss and coefficient of friction of Al –Si alloy Iron oxide composites using pin –on –disc wear testing rig. Composites were fabricated by two step stir casting method followed by squeeze casting method. Taguchi and Analysis of variance (ANOVA) were used to investigate the influence of factors on the wear loss and co efficient of friction of the composites. It was found that the applied load was the most dominant factor influencing the wear loss followed by sliding velocity and weight percentage of Iron oxide. On the other hand, iron oxide content was the most influencing factor followed by sliding velocity and applied load on the coefficient of friction of composites.
Object Detection in Images using Region Based CNN

Object detection is the task of recognizing and localizing objects in an image. Object detection in images have many applications including object counting, Visual Search Engine, security, surveillance etc. Deep Learning based techniques for object detection are divided into two categories as region based approch and single shot approach. In this paper, region based approach technique Faster R-CNN was implemented using ResNET architecture of Convolutional Neural Network(CNN). The architecture of ResNET is modiﬁed to incorporate region proposal network to propose probable region of interest in an image and classiﬁcation and regression network to detect and classify objects and their boundary in an image. The results were compared with Faster R-CNN based on VGG-16 on PASCAL VOC dataset . It was found that Faster R-CNN based on ResNET provides mean average precision of 0.78 which is better performance on PASCAL VOC dataset than VGG-16 architecture with mean average precision of 0.699.

Assessment of human thermal comfort in street canyons. An example of typical structures (Lodz, Poland)

An urban form has undeniable influence on microclimatic and human thermal conditions in strongly urbanized areas. In this context, this paper aims at evaluating the ability of the layout of street canyons to provide proper outdoor conditions in the human realm. The research is focused on the assessment of human thermal comfort depending on the configuration of the selected streets, which are located in the main city’s area of the revitalization process. The ENVI-met application, which is widely used in urban climatology, is applied to estimate the impact of the street’s layout on human comfort. Thermal indices such as: SET, PMV, PET and UTCI are implemented to describe conditions prevailing in the street canyons. Furthermore, the results are compared with the literature findings.

Analytic combinatorics of graphs

Sadly, I will not have time in those notes to illustrate those qualities. Instead, I will focus on the variety of graph models and constraints that can be investigated using analytic combinatorics. We first present classic results on connected (multi)graphs and the structure of random (multi)graphs. Then variants of the classic graph model are introduced, with constraints on the degrees of the vertices, the subgraphs allowed, the number of vertices allowed in each edge (hypergraphs), or with colored vertices which connectivity varies according to their color (inhomogeneous graphs). This presentation focuses on the combinatorial decompositions and the generating function manipulations, avoiding most of the analytic technicalities.
Titanium dioxide nanostructures chemical sensor

Titanium dioxide (TiO2) nanostructures were grown directly on the sensitive area of the transducer. A titanium thin film was deposited on 2 · 2 mm2 alumina substrates by RF magnetron sputtering and hydrothermal method was used to achieve TiO2. This method is characterized by the use of different solutions (KOH, NaOH), a not stirred pressure reactor and a heating system. As-prepared samples require an acid treatment followed by a calcination step to obtain pure TiO2 nanostructures. The nanostructured morphology was confirmed by a scanning electron microscope (SEM) and their structural properties were investigated by RAMAN spectroscopy. Obtained samples were used as gas sensors, and their behaviour towards several gaseous species was analysed in a wide range of working temperatures. Measurements were carried out in a test chamber, investigating the change in the electrical conductance due to the surrounding atmosphere. © 2016 The Authors. Published by Elsevier Ltd.

New records of the enigmatic Clytoctantes atrogularis (Thamnophilidae) in Amazonian Brazil, with remarks on plumage, natural history, and distribution

ABSTRACT Clytoctantes atrogularis Lanyon, Stotz and Willard, 1990 (Thamnophilidae) is one of the most mysterious and poorly known birds of the Neotropics. Endemic to Amazonian Brazil, it was known only from the holotype and two sight records at the type locality in Rondônia, and a sighting of a pair with a recording on the Sucunduri River in Amazonas. Here we review the distribution and report five new records in the states of Mato Grosso, Amazonas, and Rondônia, considerably increasing the known range of the species. We present the first detailed descriptions of males, for which the plumage was previously unknown. The records presented herein were made in terra firme forest with understories dominated by Lepidocaryum palms and also with sparse Guadua spp. of bamboo, demonstrating that the bird species occurs in habitats other than those previously described. Stomach contents of six individuals included mostly ants and their eggs, possibly obtained by opening stems of Guadua spp. The high rate of deforestation that characterizes a large part of the range of C. atrogularis could be causing declines in local populations.
INTERSECTIONS AND COLLISIONS OF SIMPLE RANDOM WALKS IN Z

In this paper, we prove the known result of the expectation of the number of intersections and collisions of two independent simple symmetric random walks on Zd. We also present a demonstration of the calculated result using simulations and plot the empirical expectation obtained for both the intersections and collisions. One of the main tools used to compute the result is the local central limit theorem which is used to estimate the probability of finding the random walk at a point x after n steps.
Lactococcus garvieae strains isolated from rainbow trout and yellowtail in Australia, South Africa and Japan differentiated by repetitive sequence markers

Lactococcus garvieae is an emerging important epizootiological pathogen. A total of 25 Lactococcus garvieae isolates from diseased rainbow trout (Oncorhynchus mykiss) and yellowtail (Seriola quinqueradiata) from Japan, South Africa and Australia (Tasmania and Victoria) and type strains were analysed by repetitive sequence based PCR targeting repetitive extragenic palindromes (REP) and BOX interspersed DNA sequences. Both primer sets generated five different banding profiles with isolates from South Africa, Tasmania and Victoria sharing common profiles. Japanese isolates could easily be distinguished from all other isolates on the basis of banding profile and BOX primers enabled differentiation of capsular types for these strains. The type strain L. garvieae NCFB 2157 produced a unique profile significantly different from other strains with both oligonucleotide primer sets. REP-PCR and BOX-PCR offer a rapid, cost effective and straightforward means for strain differentiation of this important fish and emerging zoonotic pathogen.

RESPON SUPLEMENTASI MINERAL ZINK (Zn) TERHADAP KECERNAAN IN-VITRO RANSUM TONGKOL JAGUNG AMONIASI

The present research was conducted to investigate the effect supplementation of mineral zinc on in-vitro digestibility of ammoniated corn cobs ration. The objective of this experiment is to determine the optimum level of zinc supplementation to in the ration through in-vitro digestibility trial. The rations consisted of 50% ammoniated corn cobs and 50% concentrates. The treatments was various levels of zinc of 0, 50, 100, 150 and 200 mg/kg of ration based on DM basis. Parameters measured included digestibility of fiber fractions (NDF, ADF, sellulosa and hemisellulosa). Data were statistically analyzed by variance analysis in a block randomized design. Results showed that the treatmens gave hightly significant (P<0,01) effect on the digestibility. Digestibility of fibers fractions increased as increasing level of zinc supplementation. The best digestibility of fibers fractions was found on 100 mg/kg of Zinc supplementation in the ration as dry matter basis
KOSZUL DUALITY OF QUADRATIC OPERADS

In this expository paper, we discuss Koszul duality as a method of explicitly constructing minimal models for quadratic dg operads. We define Koszul operads, which are quadratic operads whose Koszul complexes are acyclic. Our main result is that the minimal model of a Koszul operad is the cobar complex of its Koszul dual cooperad.
The Risk-Taking Channel of Monetary Policy and Foreign Banks

In this paper, I examine heterogeneity in the bank risk-taking channel of monetary policy using a sample of 208 domestic and foreign-owned banks from 22 OECD countries. I introduce a simple, static model advanced by Dell’Ariccia and Marquez (2013) to detail the theoretical underpinnings of this monetary policy transmission channel. I document the existence of the risk-taking channel of monetary policy and, in the main contribution of this paper, I examine whether this transmission channel has heterogeneous effects on foreign-owned versus domestic banks. I find consistent evidence that foreign banks take less risk than domestic banks following a monetary policy easing, which is robust to a variety of risk measures. The results suggest that in tranquil periods, foreign banks are more insulated from the monetary policy conditions of their host country, but that this advantage disappears during crisis periods. The ability of foreign-owned banks to access to parent bank funding via internal capital markets is the most convincing explanation for the differential response to a policy rate reduction. ∗I am very grateful to my advisor, Professor Andrés Rodŕıguez-Clare, for his insightful suggestions and invaluable guidance throughout this research project. I would also like to thank Professor David Sraer, as well as Dr. Mauricio Ulate, for incredibly helpful comments that helped guide many of these ideas. Email: noahforougi@berkeley.edu
