Predictors of Participation in AA-Related Helping : Findings from Project MATCH

Objective—The purpose of this paper is to identify the factors that distinguish those who engage in AA-related helping (AAH) following treatment intake. Method—Data were derived from Project MATCH, a longitudinal prospective investigation of the efficacy of three behavioral treatments for alcohol abuse and dependence. Cox regression analysis was performed to determine the extent to which demographic, clinical, belief, and AA affiliation factors predicted initial participation in AAH over the course of 15-months following treatment intake. Results—Demographic characteristics, drinking severity, and antisocial personality did not distinguish helpers. Increased religiosity, drinking self-efficacy, and AA affiliation predicted initial participation in AAH. Individuals reported elevated depression prior to participating in AAH, lower depression at initial engagement in AAH, and similarly lower depression in the interval following initial participation in AAH. Conclusions—The profile of prospective helpers in AA is not limited to individuals from certain backgrounds or higher functioning in terms of drinking or clinical severity. To increase participation in AA-related helping and hence outcomes, results suggest strengthening self-efficacy and meaning in life.
Constructing virtual worlds using dense stereo

We present Virtualized Reality, a technique to create virtual worlds out of dynamic events using densely distributed stereo views. The intensity image and depth map for each camera view at each time instant are combined to form a Visible Surface Model. Immersive interaction with the virtualized event is possible using a dense collection of such models. Additionally, a Complete Surface Model of each instant can be built by merging the depth maps from different cameras into a common volumetric space. The corresponding model is compatible with traditional virtual models and can be interacted with immersively using standard tools. Because both VSMs and CSMs are fully three-dimensional, virtualized models can also be combined and modified to build larger, more complex environments, an important capability for many non-trivial applications. We present results from 3D Dome, our facility to create virtualized models.
Data‐driven density estimation in the presence of additive noise with unknown distribution

Summary. We study the model Y=X+ɛ. We assume that we have at our disposal independent identically distributed observations Y1,…,Yn and ɛ−1,…,ɛ−M. The (Xj)1jn are independent identically distributed with density f, independent of the (ɛj)1jn, independent identically distributed with density f. The aim of the paper is to estimate f without knowing f. We first define an estimator, for which we provide bounds for the integrated L2‐risk. We consider ordinary smooth and supersmooth noise ɛ with regard to ordinary smooth and supersmooth densities f. Then we present an adaptive estimator of the density of f. This estimator is obtained by penalization of a projection contrast and yields to model selection. Lastly, we present simulation experiments to illustrate the good performances of our estimator and study from the empirical point of view the importance of theoretical constraints.
User Intent Discovery using Analysis of Browsing History

The search engine can retrieve the information from the web by using keyword queries. The responsibility of search engines is getting the relevant results that met with users’ search intents. Nowadays, all search engines provide search log of the user (queries logs, click information besides browsing history). The main objective of this work is to provide features that can help users during their web search by categorizing related browsing URLs together. That will be done by identifying intent groups for each URLs category, then identifying intent-segments for each intent group. Upon clustering the query categories, groups, and intent segments search engines can improve the representation of users’ search context behind the current query, this would help search engines to discover the user’s intents during the web search. Through the use of the normalized discounted cumulative gain (NDCG), the experimental results show the proposed method can improve the performance of the search engine.
The spontaneous fluctuation of the excitability of a single node modulates the internodes connectivity: A TMS‐EEG study

Brain effective connectivity can be tracked by cerebral recruitments evoked by transcranial magnetic stimulation (TMS), as measured by simultaneous electroencephalography (TMS‐EEG). When TMS is targeting the primary motor area, motor evoked potentials (MEPs) can be collected from the “target” muscles. The aim of this study was to measure whether or not effective brain connectivity changes with the excitability level of the corticospinal motor pathway (CSMP) as parameterized by MEP amplitude. After averaging two subgroups of EEG‐evoked responses corresponding to high and low MEP amplitudes, we calculated the individual differences between them and submitted the grand average to sLORETA algorithm obtaining localized regions of interest (RoIs). Statistical differences of RoI recruitment strength between low and high CSMP excitation was assessed in single subjects. Preceding the feedback arrival, neural recruitment for stronger CSMP activation were weaker at 6–10 ms of homotopic sensorimotor areas BA3/4/5 of the right nonstimulated hemisphere (trend), weaker at 18–25 ms of left parietal BA2/3/40, and stronger at 26–32 ms of bilateral frontal motor areas BA6/8. The proposed method enables the tracking of brain network connectivity during stimulation of one node by measuring the strength of the connected recruited node activations. Spontaneous increases of the excitation of the node originating the transmission within the hand control network gave rise to dynamic recruitment patterns with opposite behaviors, weaker in homotopic and parietal circuits, stronger in frontal ones. The effective connectivity within bilateral circuits orchestrating hand control appeared dynamically modulated in time even in resting state as probed by TMS.

INFLUENCE OF IMMUNE STIMULATORS ON VIRAL LEUKEMOGENESIS *

Injection of RNA, extracted from statolon by the SDS-phenol method, into FLV-infected mice 24 hours before SRBC immunization restored the immune response to SRBC to normal levels. Leukemosuppression was observed in 50% of the RNA-treated FLV-infected mice. These RNA-treated mice were clinically normal 25 days after infection, whereas all untreated infected mice developed erythroleukemia. Furthermore, all RNA-treated mice with suppressed erythroleukemia produced antibody which was cytotoxic for Friend leukemia cells. Our studies, and studies by others, indicate that the immunostimulatory and leukemosuppressive principle in statolon appears to be a dsRNA.
Effects of Pranlukast, a Leukotriene Receptor Antagonist, on Airway Inflammation in Mild Asthmatics

To determine the anti-inflammatory actions of pranlukast, a cysteinyl leuklotriene receptor antagonist, we measured exhaled nitric oxide (NO) concentrations and eosinophil ratio in induced sputum of three groups of mild asthmatics (n = 30): treated with bronchodilators alone, with bronchodilators and inhaled steroid (beclomethasone dipropionate; 400 μg/day), and bronchodilators and pranlukast (450 mg/day). Pranlukast (450 mg/day) reduced the eosinophil ratio in the induced sputum significantly (p < 0.01) without a major effect on the concentration of exhaled NO. Pranlukast also increased values of peak expiratory flow significantly (p < 0.05). Pranlukast may be useful for mild asthmatics, in part through its ability to suppress eosinophilic airway infiltration.
Charge Density-Based 3D Model Retrieval Using Bag-of-Feature

As the number of 3D models is growing on the internet and other domain-specific datasets, the search and retrieval of such models are attracting a lot of attention. A shape descriptor it plays critical roles in the retrieval quality enhancement. In this paper we propose a new robust shape descriptor based on the distribution of charge density on the surface of a 3D model. After calculating the charge density for each triangular face of each model as local features, we utilize the Bag-of-Features framework to perform global matching using the local features. Our experiments on the McGill and PSB datasets show that the proposed descriptor is robust to a variety of modifications and transformations and offers a higher retrieving quality compared to other well-known approaches.
An NLP Assistant for Clide

This report describes an NLP assistant for the collaborative development environment Clide, that supports the development of NLP applications by providing easy access to some common NLP data structures. The assistant visualizes text fragments and their dependencies by displaying the semantic graph of a sentence, the coreference chain of a paragraph and mined triples that are extracted from a paragraph's semantic graphs and linked using its coreference chain. Using this information and a logic programming library, we create an NLP database which is used by a series of queries to mine the triples. The algorithm is tested by translating a natural language text describing a graph to an actual graph that is shown as an annotation in the text editor.
The treasure deposits of Troy: rethinking crisis and agency on the Early Bronze Age citadel

Abstract The treasure deposits of Troy have been largely studied in isolation from both architectural developments and other depositional contexts in Troia II–III. The corpus has been perceived as little more than a catalogue of information that can be assessed to outline various trends related to metallurgical production, expanding networks of exchange and fluctuations in economic wealth. Considerations of agency have been few and limited. This study relates the content and context of the treasures to depositional and architectural patterns that begin in Troia II. Meaningful continuities and transformations between Troia II–III ultimately challenge the widely held reconstruction that the treasures were a concealment of wealth in anticipation of an attack. The study arrives at an alternative explanation with a consideration of the relationship between the destruction and abandonment of the Troia II central megaron complex and the deposition of treasure. The central megaron complex and the treasure deposits represent two distinct and divergent strategies of élite initiative on the citadel. The study concludes with a consideration of the inherently destabilising practices of treasures deposition, the final destruction of Troia III and the end of the Early Bronze Age in Anatolia. Özet Troya'daki hazine gömüleri büyük çoğunlukla hem mimari gelişmelerden hem de Troya II–III evreleri diğer gömülerinden bağımsız olarak incelenmiştir. Bu nedenle bu çalışmalar sonucu oluşturulmuş yazılı açıklamalar metalurjik üretim, iletişim ağlarındaki genişleme, ekonomik refahtaki dalgalanmalar gibi farklı çizgiler izlenerek oluşturulabilecek taslak niteliğindeki kataloklardan daha fazla bilgi vermemektedir. Dönemsel faaliyetleri göz önüne alan çalışma çok az sayıda ve kısıtlıdır. Bu çalışma Troya II ile başlamak üzere gömüleri ve mimari modelleri ilişkilendirerek gömünün hem içeriğini, hem de ortaya çıkarıldığı ortamı incelemektedir. Troya II ve III arasında gözlenen anlamlı süreklilik ve değişmeler, geniş bir kesim tarafından kabul gören -hazine gömülerinin tahmin edilen bir saldırı için refahın gizlenmesi- olduğu görüşüne karşı fikirler ortaya çıkarmıştır. Bu çalışma, Troya II merkezi megaron kompleksinde meydana gelen yıkım ve terk edilmiş olma ile hazine gömüleri arasındaki ilişkiyi değerlendirerek alternatif bir açıklamaya ulaşmıştır. Merkezi megaron kompleksi ile hazine gömüleri kale durumundaki bu kentte elit inisiatifinin birbirinden farklı ve zıt iki stratejisini temsil eder. Çalışma yöre halkına miras kalmış olan düzensiz gömü uygulaması, Troya III deki nihai yıkım ve Anadolu'da Erken Bronz Çağ'ın bitimini dikkate alarak bir sonuca ulaşmaktadır.
How motor speed of a robot face can influence the "older" user's perception of facial expression?

The aim of this paper is to give a short overview on how facial expressions enhance interaction with elderly people. Two studies were done. The first one was an online questionnaire that gave information on what type of expressions were more appropriate and the second one was an experiment in which participants met the robot. This study's results suggested a correlation between facial expressions and interaction enhancement. Participants preferred a certain motor speed according to the facial expression presented which shows that speed has an influence on understanding expressions and beyond this, emotions. In the end, this paper presents some ways of enhancing interaction with the robot.
Floating-ECC: Dynamic Repositioning of Error Correcting Code Bits for Extending the Lifetime of STT-RAM Caches

Spin-Transfer Torque RAM (STT-RAM) is a promising alternative to SRAM for implementing on-chip L2 and L3 caches. One of the most critical challenges in STT-RAM is reliability due to limited write endurance, which results in insufficient lifetime, as well as various types of errors. Previous studies have focused on either presenting various cache architectures/management techniques to improve the lifetime of STT-RAM caches or utilizing different Error Correcting Codes (ECCs) to protect against the permanent and transient errors. However, there is no quantitative analysis in the literature to determine the impact of ECCs on the lifetime of the STT-RAM caches. This paper formulates this impact and demonstrates that ECCs shorten the lifetime of STT-RAM cache lines by more than 50 percent due to ECCs high write activity. Then, we propose the Floating-ECC architecture for increasing the lifetime of the STT-RAM caches. The main idea is to evenly distribute the ECC write activity over all bits of cache lines by periodically relocating the ECC bits inside the cache lines. The simulation results for the most conventional ECC scheme, i.e., interleaved Single Error Correction-Double Error Detection (SEC-DED), show that Floating-ECC increases the lifetime of L2 and L3 caches by more than 318 percent and 254 percent, respectively.
Perceptual Lightness Modeling for High-Dynamic-Range Imaging

The human visual system (HVS) non-linearly processes light from the real world, allowing us to perceive detail over a wide range of illumination. Although models that describe this non-linearity are constructed based on psycho-visual experiments, they generally apply to a limited range of illumination and therefore may not fully explain the behavior of the HVS under more extreme illumination conditions. We propose a modified experimental protocol for measuring visual responses to emissive stimuli that do not require participant training, nor requiring the exclusion of non-expert participants. Furthermore, the protocol can be applied to stimuli covering an extended luminance range. Based on the outcome of our experiment, we propose a new model describing lightness response over an extended luminance range. The model can be integrated with existing color appearance models or perceptual color spaces. To demonstrate the effectiveness of our model in high dynamic range applications, we evaluate its suitability for dynamic range expansion relative to existing solutions.
Adaptive LSAS transmission for energy optimisation in low density cellular networks

This paper proposes an adaptive framework for optimising energy efficiency in large scale antenna systems (LSAS) by utilising knowledge about the users' requirement and properties in a novel discontinuous transmission (DTx) scheme. The users' requirement includes bit rate and latency while the users' properties include pathloss between the Macro basestation (MBS) and users, and information about the average received interference by each user. The proposed DTx divides the transmission into L scheduled transmissions (STs). In each ST, one or more users will be released from the overall scheduled transmission hence, leaving more spectrum for the remaining users that require longer transmission. It will be shown that the proposed scheme provides energy efficiency (EE) and Quality of Service (QoS) improvement for various number of users. This demonstrates that DTx based LSAS is an effective candidate for future cellular network for suburban and rural area.
Evidence for Repressional Role of an Inverted CCAAT Box in Cell Cycle-dependent Transcription of the Human DNA Topoisomerase IIα Gene*

Expression of DNA topoisomerase IIα (topo IIα) is cell cycle-regulated at both the transcriptional and the post-transcriptional levels. In order to identifycis-acting elements responsible for transcriptional regulation during the cell cycle, we investigated NIH/3T3 cells stably transfected with luciferase reporter plasmids containing various lengths of the human topo IIα gene promoter. Serum-deprived cells expressed low levels of luciferase, and following serum-induced cell cycle re-entry luciferase levels were gradually elevated 2-fold. During S phase, a steep 3-fold increase in luciferase activity was seen, reaching its maximum approximately 22 h after serum addition. This pattern was observed with both a full-length (nucleotides (nt) −295 to +90] and a deletion (nt −90 to +90) promoter construct. In contrast, when testing a deletion construct (nt −51 to +90) lacking the first inverted CCAAT box (ICB1) the S phase-specific induction was absent. Mutation of ICB1 revealed that it had a repressive character, since luciferase levels rose rapidly to maximal levels immediately following serum addition. Furthermore, electrophoretic mobility shift assays demonstrated a marked decrease in ICB1 binding activity following serum addition. Together, this suggests a role of ICB1 in cell cycle-dependent repression of topo IIα transcription.
Analyses morphométriques des bovinés néolithiques d'Europe tempérée (VIe millénaire avant J.-C.) : distinction des taxons domestique et sauvage du Rubané

La diffusion de la culture Rubanee permet l'introduction des premiers cheptels domestiques en Europe centrale et occidentale temperee. Jusqu'alors, aucune etude osteometrique de synthese a l'echelle de cette culture n'a ete realisee, les donnees etant dispersees entre des publications de divers pays. Il s'agit, dans ce travail, d'analyser morphometriquement a l'aide de methodes statistiques les jeux de donnees osteometriques presents dans la bibliographie des sites du Neolithique Rubane d'Europe temperee pour les bovines domestiques et sauvages. Le corpus se compose des donnees de 83 sites provenant de six pays : France, Allemagne, Autriche, Hongrie, Republique Tcheque et Pologne. Cela permet d'etudier les Bovines a travers une aire geographique etendue. Differencies dans les etudes de faune selon le critere de la taille, des problemes de determination specifique des bovines peuvent exister dans les assemblages. A travers des analyses morphometriques considerant le critere de la conformation, nous avons reussi a definir l'intervalle de recouvrement des donnees metriques des bœufs domestiques mâles et d'aurochs sauvages femelles qui n'avait jamais pu etre etabli jusqu'alors. Nous avons reevalue les parts respectives du Bœuf et de l'Aurochs dans les assemblages europeens et estime la proportion de restes sur lesquels nous ne pouvons pas nous prononcer. Ainsi, nous avons pu constater qu'il semble que la presence de l'Aurochs ait ete surestimee dans l'ensemble des sites du Rubane. Toutefois, la proportion de restes sur lesquels nous ne pouvons pas nous prononcer se revele importante.
Challenging the “ Linguistic Incompetency Hypothesis ” : Language Competency Predicts Code-Switching

Code-switching, or code-mixing, is often defined as the use of two languages within a single discourse, sentence, or constituents (Lanza, 1992; Myers-Scotton, 1993; Poplack, 1980). Most studies on children’s codeswitching are based on naturalistic observations and investigated all forms of switching or mixing, either between utterances or within utterances (e.g., Genesee, Nicoladis, Paradis, 1995; Grim, 2008; Mishina-Mori, 2011; Quay, 2008). In this paper, we refer to code-switching and code-mixing synonymously as the use of two or more languages, such as a word, an utterance, or a conversation, in a single unit of discourse (Genesee, Paradis, & Crago, 2004; Meisel, 1989). Past studies viewed children’s early code-switching as an inability to differentiate two language systems (Redlinger & Park, 1980, Volterra & Taeschner, 1978). Redlinger and Park (1980) argued that the decreasing of mixing rate as the children spoke more complex sentences was an evidence of a transition process from an undifferentiated single language system to two distinct language systems. However, further examinations of young children’s mixed utterances revealed that they are able to differentiate the two language systems. For example, by the age of age 1;10, a child is able to use languagespecific morphology in the appropriate context (Deuchar & Quay, 1998). In addition, studies showed that children do not use inflections of both languages interchangeably (e.g., Siri’s data in Lanza, 1992). In Siri’s case, she only used English grammatical morpheme with English lexical morpheme, such as “looks”, but she used Norwegian grammatical morphemes with both Norwegian and
In vitro and in vivo genotoxicity assessment of selected pharmaceuticals in relation to Escherichia coli and Cyprinus carpio

ABSTRACT Genotoxicity studies (using SOS chromotest and comet assay) of Escherichia coli and carp (Cyprinus carpio) were performed for three pharmaceutically active compounds, ciprofloxacin, 17α-ethinylestradiol and 5-fluorouracil, used in the treatment of humans. The values of genotoxicity induction coefficient (I) in the SOS chromotest clearly showed genotoxicity for ciprofloxacin, both in the presence and in the absence of S9 fraction; 17α-ethinylestradiol demonstrated slight genotoxicity at the highest tested concentration; and 5-fluorouracil did not induce genotoxic effects in Escherichia coli mutants. Statistical analysis of the results of the comet assay revealed significant differences in cell populations derived from carp placed in a solution of 5-fluorouracil in comparison with the negative control. Statistical analysis also showed a significant increase of “% DNA in tail” of comets in cell populations incubated in solutions of 17α-ethinylestradiol at concentrations of 10000, 2000 and 400 µg/L and in solutions of 5-fluorouracil with S9 fraction at concentrations of 50,000 and 2,000 μg/L in comparison with the negative controls.
Stimulus dependence of oxygenation‐sensitive MRI responses to sustained visual activation

Oxygenation‐sensitive MRI responses to repetitive and sustained visual activation were compared for stimuli with different temporal, spatial, and luminance contrasts, i.e. reversing checkerboard, flashing diffuse red light, and stationary diffuse gray light with darkness as a control. All paradigms elicited an initial oxygenation ‘overshoot’ as well as a post‐stimulus ‘undershoot’ However, whereas flashing and stationary diffuse light resulted in more than a 50% decrease of the initial signal response after 6 min of stimulation, checkerboard responses remained largely unaffected (less than 20% signal attenuation). The demonstration of a stimulus dependence for sustained visual activation reconciles apparently contradictory reports for stimuli involving checkerboards as opposed to goggles, flickerlight, and movies. It may be caused by stimulus‐dependent adjustments of neuronal activity, oxygen consumption, blood flow, or blood volume. © 1998 John Wiley & Sons, Ltd.
