Developing and integrating Java based SIP client at Srce

In order to provide multimedia services, which would allow users to participate in the modification of forms and contents of the current session in real time, we have begun to create an important component of successful online communication and education - a software based client. This kind of a smart endpoint needs to meet two conditions. The first requires the client to be platform-independent, modular and able to integrate with Web based applications. There are just a few Java based SIP clients (open source and commercial) and they do not meet the second main condition which is the process of authentication in accordance with the recommendations of the AAI@EduHr system. This paper explains the architecture of the client, the extension of authentication concept in AAI@EduHr system, which makes the client unique, as well as how we can benefit from the both.
Intelligent Mobile Computing to Assist in the Treatment of Depression

Mental health represents a social and economic problem in all European Union (EU) member nations. Although cognitive behavioral therapies (CBT) have provided an effective approach to the treatment of depression, several issues currently remain unresolved. This paper introduces a novel mobile system that provides several useful functions to improve the delivery of treatments for depressive conditions. Additionally, the system creates an environment in which such treatments can be evaluated.

Pyrosequencing Analysis of Bacterial Biofilm Communities in Water Meters of a Drinking Water Distribution System

ABSTRACT The applicability of 454 pyrosequencing to characterize bacterial biofilm communities from two water meters of a drinking water distribution system was assessed. Differences in bacterial diversity and composition were observed. A better understanding of the bacterial ecology of drinking water biofilms will allow for effective management of water quality in distribution systems.
OCR Post-processing Using Weighted Finite-State Transducers

A new approach for Stochastic Error-Correcting Language Modeling based on Weighted Finite-State Transducers (WFSTs) is proposed as a method to post-process the results of an optical character recognizer (OCR). Instead of using the recognized string as an input to the transducer, in our approach the complete set of OCR hypotheses, a sequence of vectors of a posteriori class probabilities, is used to build a WFST that is then composed with independent WFSTs for the error and language models. This combines the practical advantages of a de-coupled (OCR + post-processor) model with the full power of an integrated model.
News Feature: The genuine problem of fake news

Intentionally deceptive news has co-opted social media to go viral and influence millions. Science and technology can suggest why and how. But can they offer solutions? In 2010 computer scientist Filippo Menczer heard a conference talk about some phony news reports that had gone viral during a special Senate election in Massachusetts. “I was struck,” says Menczer. He and his team at Indiana University Bloomington had been tracking early forms of spam since 2005, looking mainly at then-new social bookmarking sites such as https://del.icio. us/. “We called it social spam,” he says. “People were creating social sites with junk on them, and getting money from the ads. ” But outright fakery was something new. And he remembers thinking to himself, “this can’t be an isolated case. ” Fig. 1. Fabricated social media posts have lured millions of users into sharing provocative lies. Image courtesy of Dave Cutler (artist). Of course, it wasn’t. By 2014 Menczer and other social media watchers were seeing not just fake political headlines but phony horror stories about immigrants carrying the Ebola virus. “Some politicians wanted to close the airports,” he says, “and I think a lot of that was motivated by the efforts to sow panic. ” By the 2016 US presidential election, the trickle had become a tsunami. Social spam had evolved into “political clickbait”: fabricated money-making posts that lured millions of Facebook, Twitter, and YouTube users into sharing provocative lies—among them headlines claiming that Democratic candidate Hillary Clinton once sold weapons to the Islamic State, that Pope Francis had endorsed Republican candidate Donald Trump, and (from the same source on the same day) that the Pope had endorsed Clinton. Social media users were also being targeted by Russian dysinformatyea : phony stories and advertisements designed to undermine faith in American institutions, the election in particular. And all of …
Metacognition and memory for nonoccurrence.

A familiar hypothesis about the recognition of distractor items as "new" is that it depends heavily on a metacognitive strategy in which the memorability or salience of the distractor is evaluated: if the item was deemed salient or memorable and yet no memory trace for it can be found, then it must not have been studied (e.g. Strack & Bless, 1994). In four experiments, no evidence was found to support this metamemory hypothesis. Experiments 1a, 1b, and 2 demonstrated that the judged salience of the stimuli did not predict participants' recognition judgements for distractors. In Experiments 3a and 3b, instructional manipulations designed to affect the ostensible metacognitive process failed to affect the recognition judgements. Finally, Experiment 4 indicated that confidence judgements do not support the predictions of the metamemory hypothesis.
A further analysis on the use of Genetic Algorithm to configure Support Vector Machines for inter-release fault prediction

Some studies have reported promising results on the use of Support Vector Machines (SVMs) for predicting fault-prone software components. Nevertheless, the performance of the method heavily depends on the setting of some parameters. To address this issue, we investigated the use of a Genetic Algorithm (GA) to search for a suitable configuration of SVMs to be used for inter-release fault prediction. In particular, we report on an assessment of the method on five software systems. As benchmarks we exploited SVMs with random and Grid-search configuration strategies and several other machine learning techniques. The results show that the combined use of GA and SVMs is effective for inter-release fault prediction.
[Improvement of impaired memory in mice by huperzine A and huperzine B].

Both huperzine A (Hup-A) and huperzine B(Hup-B) are new alkaloids isolated from Huperzia serrata (Thunb Trev). It has been shown in this laboratory that Hup-A and Hup-B are selective AChE inhibitors which exhibit larger therapeutic indices than does physostigmine (Phy). Using a step-down method, the effects of Hup-A and Hup-B on various forms of experimentally-produced impaired memory function in mice were examined. Mice received a single training trial on a passive avoidance task followed by a retention trial 24h later. Immediately after training, each adult mouse received one of the following amnestic treatments: maximal electroconvulsive shock (MES), or an injection of scopolamine (Scop), NaNO2 or cycloheximide (CXM). Step-down latency (SDL) and escape latency (EL) were measured and used as parameters of memory performance. In control mice. each amnestic treatment produced retrograde amnesia. However, Hup-A or Hup-B administered immediately after each of the amnestic treatments significantly reversed the MES, Scop, NaNO2- or CXM-induced disruptions of memory retention for passive avoidance tasks. Hup-A or Hup-B also markedly improved the retention of the learned task 24h later in aged mice. These improvements or normalization of impaired memory function were observed at doses of 1OO-150 yg/kg ip and 140-160 yg/kg ig (Hup-A) or of l.0-1.5 mg/kg ip and 2.4 mg/kg ig (Hup-B). Phy (0.125-0.175 mg/kg ip) for comparison, were active in all of the various experimental types of amnesia and had about 10 times the potency of Hup-B, but less than that of Hup-A.
Brain metabolite composition in relation to cognitive function and dystrophin mutations in boys with Duchenne muscular dystrophy

Duchenne muscular dystrophy (DMD) is a hereditary X‐linked recessive disorder affecting the synthesis of dystrophin, a protein essential for structural stability in muscle. Dystrophin also occurs in the central nervous system, particularly in the neocortex, hippocampus and cerebellum. Quantitative metabolic analysis by localized 1H MRS was performed in the cerebellum (12 patients and 15 controls) and a temporo‐parietal location (eight patients and 15 controls) in patients with DMD and healthy controls to investigate possible metabolic differences. In addition, the site of individual mutations on the dystrophin gene was analyzed and neuropsychological cognitive functions were examined. Cognitive deficits in the patient group were found in line with earlier investigations, mainly concerning verbal short‐term memory, visuo‐spatial long‐term memory and verbal fluency, but also the full‐scale IQ. Causal mutations were identified in all patients with DMD. Quantitative MRS showed consistent choline deficits, in both cerebellar white matter and temporo‐parietal cortex, as well as small, but significant, metabolic abnormalities for glutamate and total N‐acetyl compounds in the temporo‐parietal region. Compartment water analysis did not reveal any abnormalities. In healthy subjects, choline levels were age related in the cerebellum. The choline deficit contrasts with earlier findings in DMD, where a surplus of choline was postulated for the cerebellum. In patients, total N‐acetyl compounds in the temporo‐parietal region were related to verbal IQ and verbal short‐term memory. However, choline, the putative main metabolic abnormality, was not found to be associated with cognitive deficits. Furthermore, in contrast with the cognitive performance, the metabolic brain composition did not depend significantly on whether or not gene mutations concerned the expression of the dystrophin isoform Dp140, leading to the conclusion that the effect of the missing Dp140 isoform on cognitive performance is not mediated through the observed metabolite composition, or is caused by local effects beyond the resolution accessible to MRS investigations.

Breathing Room in Monitored Space: The Impact of Passive Monitoring Technology on Privacy in Independent Living.

PURPOSE OF THE STUDY This study examines articulations of the relationship between privacy and passive monitoring by users and former users of a sensor-based remote monitoring system. A new conceptualization of privacy provides a framework for a constructive analysis of the study's findings with practical implications. DESIGN AND METHODS Forty-nine in-depth semistructured interviews were conducted with elder residents, family members, and staff of 6 low-income independent living residence apartment buildings where the passive monitoring system had been offered for 6 years. Transcribed interviews were coded into the Dedoose software service and were analyzed using methods of grounded theory. RESULTS Five diverse articulations of the relationship between privacy and passive monitoring emerged. The system produced new knowledge about residents and enabled staff to decide how much of that knowledge to disclose to residents. They chose not to disclose to residents their reason for following up on system-generated alerts for 2 reasons: concern that feelings of privacy invasion may arise and cause dissatisfaction with the technology, and the knowledge that many resident users did not comprehend the extent of its features and would be alarmed. IMPLICATIONS This research reveals the importance and challenges of obtaining informed consent. It identifies where boundary intrusion can occur in the use of passive monitoring as well as how changes to technology design and practice could create opportunities for residents to manage their own boundaries according to their privacy needs. The diversity of approaches to privacy supports the need for "opportunity for boundary management" to be employed as both a design and practice principle.
Broadband uniplanar microstrip to slot-line transitions

New in line uniplanar microstrip-to-slotline transitions for MIC/MMIC and phased array slotline antenna applications are described. Such transitions are compact and suitable to be used in an open environment or inside a package or a multichip module. The transitions share the concept of using a balun which consists of two microstrip lines connected to a slotline through a pair of coupled microstrips. In this paper, the transitions are studied theoretically using the FDTD technique and measured experimentally using an HP8510C Network Analyzer. For a back-to-back configuration, an insertion loss of less than 1.3 dB per transition is achieved over a 40% 3-dB bandwidth with a minimum of 0.6 dB at the design frequency. <<ETX>>
Synthesis of a Cu2+-Selective Probe Derived from Rhodamine and Its Application in Cell Imaging

A new fluorescent probe P based on rhodamine for Cu2+ was synthesized and characterized. The new probe P showed high selectivity to Cu2+ over other tested metal ions. With optimal conditions, the proposed probe P worked in a wide linear range of 1.0 × 10−6−1.0 × 10−5 M with a detection limit of 3.3 × 10−7 M Cu2+ in ethanol-water solution (9:1, v:v, 20 mM HEPES, pH 7.0). Furthermore, it has been used for imaging of Cu2+ in living cells with satisfying results.
Série Scientifique Scientific Series 2011 s14 Dynamic Price Dependence of Canadian and International Art Markets : An Empirical Analysis

Although the market for Canadian paintings is now of substantial magnitude, with several works having recently sold for well over a million dollars, it remains true that with very few exceptions, the works of Canadian painters are bought and sold only in Canada and held only by Canadian collectors. This market can thus be viewed as almost exclusively local, and it is therefore not clear that there should be any linkage between price movements for Canadian art and those for the mainstream international market in old master, impressionist, and modern art. This paper investigates the presence and nature of such time series dependence econometrically, both in terms of long term trends as reflected in the co-integrating relationship between Canadian and the international market, and in terms of short-run comovements as represented in correlations. The possibility that the local market "follows" the international one is also considered through an analysis of Granger-Causality. For Canadian art prices we use a new hedonic index that has been computed using an updated version of the data set of Hodgson and Vorkink (2004), while for the international prices, we use an index provided by Mei and Moses.

Hypoglycemic effects of Ganoderma applanatum and Collybia confluens exo‐polymers in streptozotocin‐induced diabetic rats

The hypoglycemic effects of Ganoderma applanatum exo‐polymer (GAE) and Collybia confluens exo‐polymer (CCE) produced by submerged mycelial cultures in streptozotocin (STZ)‐induced diabetic rats were investigated. Hypoglycemic effects were achieved in both the GAE‐ and CCE‐treated groups by administration at a level of 100 mg/kg body weight (BW) daily for 3 weeks. The administration of GAE and CCE substantially reduced the plasma glucose levels by as much as 22.0% and 25.9%, respectively, when compared with the control group. The GAE and CCE also lowered the plasma total cholesterol and triglyceride levels by 20.3% and 22.5%, and by 22.7% and 25.5%, respectively. Furthermore, the activity of alanine transaminase (ALT) and aspartate transaminase (AST) was decreased by 23.2% and 20.7% in the GAE‐treated group, and it was also reduced by 28.7% and 23.6% in the CCE‐treated group. The results strongly demonstrate the potential of GAE and CCE in combating diabetes in experimental animals. Copyright © 2007 John Wiley & Sons, Ltd.
12-009 Least-squares methods for policy iteration ∗

Approximate reinforcement learning deals with the essential problem of applying reinforcement learning in large and continuous state-action spaces, by using function approximators to represent the solution. This chapter reviews leastsquares methods for policy iteration, an important class of algorithms for approximate reinforcement learning. We discuss three techniques for solving the core, policy evaluation component of policy iteration, called: least-squares temporal difference, least-squares policy evaluation, and Bellman residual minimization. We introduce these techniques starting from their general mathematical principles and detailing them down to fully specified algorithms. We pay attention to online variants of policy iteration, and provide a numerical example highlighting the behavior of representative offline and online methods. For the policy evaluation component as well as for the overall resulting approximate policy iteration, we provide guarantees on the performance obtained asymptotically, as the number of samples processed and iterations executed grows to infinity. We also provide finite-sample results, which apply when a finite number of samples and iterations are considered. Finally, we outline several extensions and improvements to the techniques and methods reviewed.

Using multiple-precision arithmetic

High-precision arithmetic is useful in many different computational problems. The most common is a numerically unstable algorithm, for which, say, 53-bit (ANSI/IEEE 754-1985 Standard) double precision would not yield a sufficiently accurate result. For most current machines, 53-bit double precision is the highest provided in hardware, giving about 16 significant digits. (By "significant digits", I mean the number of equivalent decimal digits of precision, rather than the number with base /spl ne/ 10.) Calculating with 30 or 40 significant digits can often overcome the algorithm's instability and provide adequate accuracy. In the article, I give some examples of calculations in which multiple precision can be useful.
Resistance Determinants and Clonal Diversity in Group A Streptococci Collected during a Period of Increasing Macrolide Resistance

ABSTRACT Susceptibility to macrolides and lincosamides was investigated with 299 consecutive nonduplicate Streptococcus pyogenes clinical isolates collected over a 6-year period (1992 to 1997) from an area of central Italy. During this period, macrolide resistance rates steadily increased (from 9% in 1992 to 53% in 1997; P < 0.001). The increase was caused by isolates with a macrolide-lincosamide-streptogramin B resistance phenotype, carrying mostly erm(B) but also erm(TR) genes, that were not detected in the first 2 years and were detected with increasing prevalence (8, 5, 26, and 37%, respectively) during the following 4 years. During the same period, the prevalence of isolates with a macrolide resistance phenotype, carrying mef(A) determinants, did not vary significantly; on average it was 13%, with modest rate fluctuations in different years and no definite trend. Molecular typing revealed a remarkable clonal diversity among susceptible and resistant isolates and a notable heterogeneity of the genetic environment of the resistance genes. The analysis of clonal diversity in relation with resistance phenotypes and genotypes revealed that increased macrolide resistance rates were due to a complex interplay of different mechanisms, with a relevant contribution played by an “epidemic” spread of genetic elements carrying the erm(B) gene among the circulating streptococcal population.
HYPERTENSION AND OXIDATIVE STRESS

1 Oxidative stress has been suggested to be involved in the pathogenesis of hypertension. This may be via a number of possible mechanisms, including quenching of the important vasodilator nitric oxide. 2 Animal studies have generally supported the hypothesis that increased blood pressure is associated with increased oxidative stress. However, human studies have been inconsistent and may differ owing to the populations studied and the various methods used. Treatment with anti‐oxidants has been suggested to lower oxidative stress and, therefore, blood pressure. However, to date, studies investigating single or combination supplements have failed to show any consistent benefit. 3 Overall, the evidence supporting the link between hypertension and oxidative stress remains inconclusive, with methodological and population differences possibly confounding results. Further studies investigating this relationship are warranted.
Precision-recall space to correct external indices for biclustering

Biclustering is a major tool of data mining in many domains and many algorithms have emerged in recent years. All these algorithms aim to obtain coherent biclusters and it is crucial to have a reliable procedure for their validation. We point out the problem of size bias in biclustering evaluation and show how it can lead to wrong conclusions in a comparative study. We present the theoretical corrections for all of the most popular measures in order to remove this bias. We introduce the corrected precision-recall space that combines the advantages of corrected measures, the ease of interpretation and visualization of uncorrected measures. Numerical experiments demonstrate the interest of our approach.
