Mechanisms underlying response bias in deception detection

Abstract The present research aims to explore the mechanisms underlying response bias in detection of deception. In addition to examining the predictive value of generalized communicative suspicion (GCS), age, and professional experience, the present approach also investigates the role of error weighting by testing the hypothesis that a greater concern about Misses is associated with a lie bias. In Study 1, we analyzed samples of (a) students, (b) police trainees, and (c) police officers. Results revealed an asymmetrical error weighting as the strongest predictor of response bias. Supporting our hypothesis, participants who were more concerned about False Alarms were particularly truth biased, whereas a lie bias was observed among those who were more concerned about Misses. In Study 2, we manipulated the error weighting in order to test its causal relation to response bias. Results again show the predictive value of asymmetrical error weighting for response bias in deception detection, and indicate that the effects of the manipulation are moderated by individuals' habitual error weighting.
Low cost robot arm with visual guided positioning

Low cost robotic solutions are of great importance for improvement and development of robotics. In this paper, two visually guided low cost robot arms are proposed. The proposed system performs automatic hand-eye calibration and, after the calibration, positions its end effector above the object of interest using visual servoing based on off the shelf marker tracker. The presented experiments demonstrate positioning accuracy of the proposed setup.
Metalogue: A Multiperspective Multimodal Dialogue System with Metacognitive Abilities for Highly Adaptive and Flexible Dialogue Management

This poster paper presents a high-level description of the Metalogue project that is developing a multi-modal dialogue system that is able to implement interactive behaviors that seem natural to users and is flexible enough to exploit the full potential of multimodal interaction. We provide an outline of the initial work undertaken to define a an open architecture for the integrated Metalogue system. This system includes components that are necessary for the implementation of the processing stages for a variety of application domains: initialization, training, information gathering, orchestration, multimodality, dialogue management, speech recognition, speech synthesis and user modelling.
The structural and functional diversity of Hsp70 proteins from Plasmodium falciparum

It is becoming increasingly apparent that heat shock proteins play an important role in the survival of Plasmodium falciparum against temperature changes associated with its passage from the cold‐blooded mosquito vector to the warm‐blooded human host. Interest in understanding the possible role of P. falciparum Hsp70s in the life cycle of the parasite has led to the identification of six HSP70 genes. Although most research attention has focused primarily on one of the cytosolic Hsp70s (PfHsp70‐1) and its endoplasmic reticulum homolog (PfHsp70‐2), further functional insights could be inferred from the structural motifs exhibited by the rest of the Hsp70 family members of P. falciparum. There is increasing evidence that suggests that PfHsp70‐1 could play an important role in the life cycle of P. falciparum both as a chaperone and immunogen. In addition, P. falciparum Hsp70s and Hsp40 partners are implicated in the intracellular and extracellular trafficking of proteins. This review summarizes data emerging from studies on the chaperone role of P. falciparum Hsp70s, taking advantage of inferences gleaned from their structures and information on their cellular localization. The possible associations between P. falciparum Hsp70s with their cochaperone partners as well as other chaperones and proteins are discussed.
Negative Fitness Consequences and Transmission Dynamics of a Heritable Fungal Symbiont of a Parasitic Wasp

ABSTRACT Heritable bacterial symbionts are widespread in insects and can have many important effects on host ecology and fitness. Fungal symbionts are also important in shaping their hosts' behavior, interactions, and evolution, but they have been largely overlooked. Experimental tests to determine the relevance of fungal symbionts to their insect hosts are currently extremely rare, and to our knowledge, there have been no such tests for strictly predacious insects. We investigated the fitness consequences for a parasitic wasp (Comperia merceti) of an inherited fungal symbiont in the Saccharomycotina (Ascomycota) that was long presumed to be a mutualist. In comparisons of wasp lines with and without this symbiont, we found no evidence of mutualism. Instead, there were significant fitness costs to the wasps in the presence of the yeast; infected wasps attacked fewer hosts and had longer development times. We also examined the relative competitive abilities of the larval progeny of infected and uninfected mothers, as well as horizontal transmission of the fungal symbiont among larval wasps that shared a single host cockroach egg case. We found no difference in larval competitive ability when larvae whose infection status differed shared a single host. We did find high rates of horizontal transmission of the fungus, and we suggest that this transmission is likely responsible for the maintenance of this infection in wasp populations.
The zinc-finger protein basonuclin 2 is required for proper mitotic arrest, prevention of premature meiotic initiation and meiotic progression in mouse male germ cells

Absence of mitosis and meiosis are distinguishing properties of male germ cells during late fetal and early neonatal periods. Repressors of male germ cell meiosis have been identified, but mitotic repressors are largely unknown, and no protein repressing both meiosis and mitosis is known. We demonstrate here that the zinc-finger protein BNC2 is present in male but not in female germ cells. In testis, BNC2 exists as several spliced isoforms and presumably binds to DNA. Within the male germ cell lineage, BNC2 is restricted to prospermatogonia and undifferentiated spermatogonia. Fetal prospermatogonia that lack BNC2 multiply excessively on embryonic day (E)14.5 and reenter the cell cycle prematurely. Mutant prospermatogonia also engage in abnormal meiosis; on E17.5, Bnc2−/− prospermatogonia start synthesizing the synaptonemal protein SYCP3, and by the time of birth, many Bnc2−/− prospermatogonia have accumulated large amounts of nonfilamentous SYCP3, thus appearing to be blocked at leptonema. Bnc2−/− prospermatogonia do not undergo proper male differentiation, as they lack almost all the mRNA for the male-specific methylation protein DNMT3L and have increased levels of mRNAs that encode meiotic proteins, including STRA8. Bnc2−/− prospermatogonia can produce spermatogonia, but these enter meiosis prematurely and undergo massive apoptotic death during meiotic prophase. This study identifies BNC2 as a major regulator of male germ stem cells, which is required for repression of meiosis and mitosis in prospermatogonia, and for meiosis progression during spermatogenesis. In view of the extreme evolutionary conservation of BNC2, the findings described here are likely to apply to many species.
Staphylococcus aureus colonization among nursing home residents in a large Finnish nursing home

We studied colonization with methicillin-resistant and -sensitive Staphylococcus aureus (MRSA, MSSA) in the second largest nursing home in Finland, in which the residents volunteered had their nostrils, throats, perineums, skin lesions, and catheter exit sites swabbed, and catheter urines cultured. The specimens were cultured onto non-selective and selective agar, with or without enrichment in salt-containing trypticase soy broth (TSB). S. aureus was identified by routine methods, methicillin resistance was detected by oxacillin and cefoxitin disk diffusion and MIC E-tests, and GenoType MRSA® -test was used for mecA gene confirmation. A total of 663 cultures were obtained from 213 residents. Of those, 165 specimens (25%) from 94 residents (44%) were positive for S. aureus, and 3 specimens (0.4%) from 2 (0.9%) residents were positive for MRSA. Of the 165 S. aureus isolates, 31 (19%) from 25 (27%) residents were found only from sites other than nostrils (30 MSSA and 1 MRSA). TSB enrichment detected additional 33 (5%) S. aureus isolates (32 MSSA and 1 MRSA), resulting in 8 (5%) additional residents. None of the MRSA strains would have been found if only nostrils and throat had been screened, and no enrichment broth had been used.
Real‐Time Rendering and Editing of Vector‐based Terrains

We present a method to populate very large terrains with very detailed features such as roads, rivers, lakes and fields. These features can be interactively edited, and the landscape can be explored in real time at any altitude from flight view to car view. We use vector descriptions of linear and areal features, with associated shaders to specify their appearance (terrain color and material), their footprint (effect on terrain shape), and their associated objects (bridges, hedges, etc.).
Acute vs. Chronic Stressors, Multiple Suicide Attempts, and Persistent Suicide Ideation in US Soldiers

Abstract This study examined recent-onset (i.e., acute) and persistent (i.e., chronic) life stressors among 54 acutely suicidal US Army Soldiers and examined their relationship to persistence of suicidal crises over time. Soldiers with a history of multiple suicide attempts reported the most severe suicide ideation (F(2,51) = 4.18, p = 0.021) and the greatest number of chronic stressors (F(2,51) = 5.11, p = 0.009). Chronic but not acute stressors were correlated with severity of suicide ideation (r = 0.24, p = 0.026). Participants reporting low-to-average levels of chronic stress resolved suicide ideation during the 6-month follow-up, but participants reporting high levels of chronic stress did not (Wald &khgr;2(1) = 4.57, p = 0.032). Soldiers who are multiple attempters report a greater number of chronic stressors. Chronic, but not acute-onset, stressors are associated with more severe and longer-lasting suicidal crises.
NDN Live Video Broadcasting over Wireless LAN

Named Data Networking (NDN) is a new Internet architecture that replaces today's focus on where - addresses and hosts - with what - the content that users and applications care about. One of NDN's prominent advantages is scalable and efficient content distribution due to its native support of caching and multicast in the network. However, at the last hop to wireless users, often the WiFi link, current NDN implementation still treats the communication as multiple unicast sessions, which will cause duplicate packets and waste of bandwidth when multiple users request for the same popular content. WiFi's built-in broadcast mechanism can alleviate this problem, but it suffers from packet loss since there is no MAC-layer acknowledgement as in unicast. In this paper, we develop a new NDN-based cross-layer approach called NLB for efficient and scalable live video streaming over wireless LAN. The idea is to use WiFi's broadcast channel to deliver content from the access point to the users, a leader-based mechanism to suppress duplicate requests from users, and receiver-driven rate control and loss recovery. The design is implemented and evaluated in a physical testbed comprised of a commodity residential access point and 20 WiFi clients. While NDN with multiple unicast sessions or plain broadcast can support no more than 7 concurrent viewers of a 1Mbps streaming video, NDN plus NLB supports all 20 viewers, and can likely support many more when present.
Asynchronous Patterns for Dynamic Maintenance

Software maintenance and reengineering are traditionally considered as static operations. In this article, we ad vocate that dynamic maintenance is also possible. Though adaptable applications are able to change their behavior in order to fit to the current situation and thus evolve at runtime we can hardly consider that it is maintenance, as most adaptable applications are very limited in their possibilities of evolution. In this article we describe experi ences made with the LuckyJ architecture based on decoupled asynchronous communications between components that allow to have an application completely and arbitrarily modified at runtime. In particular, we show common patterns that we discovered by experimentation.
Minimization of delays in multi-service Cloud-RAN BBU pools

Cloud Radio Access Network (C-RAN) is a cost-effective solution for cellular operators which not only offers resource allocation and interference management flexibility, but also helps them enhance the energy efficiency of the network. The key character of the C-RAN architecture is a centralized Baseband Unit (BBU) pool which consists of high-capacity processing units and real-time virtualization. However, this centralized architecture can affect the system latency. As a consequence, the minimization of the execution delay of each user services in the BBU pool can be perceived as a major performance objective. In this paper, we consider different delay sensitive services and optimize their execution time inside the BBU pool. We present a new approach of BBU selection based on queuing theory in order to minimize the response time in the BBU pool under resource cost constraint. Simulation results showed that our proposed approach is more efficient than benchmark algorithms in terms of response time and throughput.
Electrochemical performanceof LiMn2O4 with varying thickness of cathode sheet

Lithium-ion batteries are widely used as portable electrical energy storage devices because they have high energy densities and long life cycles. One of the cathode active materials used in the manufacture of Lithium-ion batteries is LiMn2O4 because of its easy and cheap manufacturing, has a long life cycle, high power applications, safe, and low toxicity of manganese basic materials. In this research, LiMn2O4 as cathode sheet has been made by doctor blade coating. This method was carried out by mixing LiMn2O4 with polyvinylidene fluoride (PVDF), Super P, and dimethylacetamide (DMAC) with weight ratio of 82.5: 10: 7.5, respectively, to obtain a well dispersed slurry. Slurry was superimposed on aluminum foil surface with various thickness of 200, 300 and 400 μm. Coin cell was assembled using electrodes, separator, lithium metal and electrolytes in the glove box. The cell battery was characterized by using cyclic voltammetry, charge discharge and electrochemical impedance spectroscopy in order to know the effect of active material thickness to cell battery performances. The results showed that active material with 400 μm in thickness had the best electrochemical performance due to a narrow and sharp reduction-oxidation peak pair, small polarization value of 0.0335 V as well as having charge and discharge capacities of 1.1249 mAh and 1.0914 mAh, respectively. Moreover, EIS result showed that 400 μm thickness of active material had highest conductivity value of 5.3922 × 10−5 Scm−1.
The Advanced Computing Systems Association beyond Cryptographic Conditional Access beyond Cryptographic Conditional Access

Conditional access (CA) systems manage charge-able content (e.g., movies). Traditional CA systems use a smartcard as a cryptographic component that decrypts broadcast content for authorized recipients. Since that approach protects content by protecting cryptographic keys, it has two inherent weaknesses: It relies on the smartcard to protect universal secrets (i.e., the broadcast keys); and it cannot protect content from redistribution. This paper describes a non-cryptographic conditional access system, where instead of protecting content directly, the content's identity is inserted as a watermark in the content and the CA smartcard is used as a licensing authority to authorize the display device to display watermarked content. This approach places a lower security burden on individual smartcards, and protects against the use of redistributed content.
RESEARCH: "Religious Framing by Individuals With PTSD When Writing About Traumatic Experiences"

Writing about traumatic events can produce physical and psychological health benefits, especially when individuals use language to transform emotionally laden events into meaningful narratives. Because religion often facilitates the search for meaning, we predicted that the use of religious themes in writing would moderate mood-related outcomes. Fifteen individuals with posttraumatic stress disorder (PTSD) wrote in each of 3 sessions about their PTSD-triggering events. Religious themes were evident in essays written by 80 percent of participants. Relative to participants who did not frame their traumas in religious terms, those who used religious framing reported a greater shift toward negative mood after the first writing session than those without such framing. By the third session, however, religious framing was associated with more positive mood after writing, whereas nonreligious framing was still associated with more negative mood. The nature of religious references was important. Positive references and specific religious behaviors (e.g., prayer) were associated with more positive mood states, whereas negative religious references were not associated with mood. Implications for research and practice are discussed.
Transforming growth factor beta 1 (TGF-beta 1) induced neutrophil recruitment to synovial tissues: implications for TGF-beta-driven synovial inflammation and hyperplasia

We have studied the consequences of introducing human recombinant transforming growth factor beta 1 (hrTGF-beta 1) into synovial tissue of the rat, to begin to better understand the significance of the fact that biologically active TGF-beta is found in human arthritic synovial effusions. Within 4-6 h after the intra-articular injection of 1 microgram of hrTGF-beta 1 into rat knee joints, extensive recruitment of polymorphonuclear leukocytes (PMNs) was observed. Cytochemistry and high resolution histological techniques were used to quantitate the influx of PMNs, which peaked 6 h post-injection. In a Boyden chamber assay, hrTGF-beta 1 at 1-10 fg/ml elicited a chemotactic response from PMNs greater in magnitude than that evoked by FMLP, establishing that TGF-beta 1 is an effective chemotactic agent for PMNs in vitro as well as in vivo. That PMNs may represent an important source of TGF-beta in inflammatory infiltrates was strongly suggested by a demonstration that stored TGF-beta 1 was secreted during phorbol myristate acetate- stimulated degranulation in vitro. Acid/ethanol extracts of human PMNs assayed by ELISA contained an average of 355 ng of TGF/beta 1 per 10(9) cells potentially available for secretion during degranulation of PMNs. [3H]Thymidine incorporation in vivo and autoradiography of tissue sections revealed that widespread cell proliferation was triggered by TGF-beta 1 injection. Synovial lining cells and cells located deep within the subsynovial connective tissue were identified as sources of at least some of the new cells that contribute to TGF-beta 1-induced hyperplasia. Our results demonstrate that TGF-beta is capable of exerting pathogenic effects on synovial tissue and that PMNs may represent a significant source of the TGF-beta present in synovial effusions.
Prevalence of Hypodontia and Associated Factors: A Systematic Review and Meta-analysis

Objectives To determine the prevalence and factors associated with hypotonia. Design Systematic review and meta-analysis. Data source A search strategy was developed along with inclusion criteria and run in MEDLINE and EMBASE (published from 2002 to August 2012) databases to reveal all studies on the prevalence of hypodontia or associated factors. A hand search of reference lists and a Google search aimed to improve the sensitivity of the literature search. Selection criteria All studies on the prevalence of hypodontia or associated factors published from 2002 onwards were included. Abstracts of non-English papers were also analyzed. Data selection and extraction All potential articles were checked against the inclusion criteria independently, and in duplicate by two investigators. A checklist was used to assess the quality of selected studies. Main outcome Prevalence of hypodontia, excluding third molars. Results The overall prevalence of hypodontia was found to be 6·4% (95% CI: 5·7, 7·2). There was a statistically significant difference in the prevalence of hypodontia by continent (Q = 34·18, P<0·001). Prevalence of hypodontia was the highest in Africa: 13·4% (95% CI: 9·7, 18·0), followed by Europe (7% CI: 6·0–8·0%), Asia (6·3% CI: 4·4, 9·1) and Australia (6·3% CI: 5·3, 7·4) with a lower prevalence in North America (5·0% CI: 4·1–5·9) and Latin America and Caribbean (4·4% CI: 3·2–6·1). Females were found to have a higher prevalence than males (combined OR 1·22; 95% CI: 1·14, 1·30). The most commonly affected teeth were mandibular second premolars followed by maxillary lateral incisors and maxillary second premolars. The prevalence of mild, moderate and severe hypodontia was found to be 81·6, 14·3 and 3·1% respectively. Conclusions There was a high variation in the prevalence of hypodontia between the studies. African populations were found to have a higher risk for tooth agenesis and there was an increased risk for females to have hypodontia than males.
Measuring cross-lingual semantic similarity across European languages

This paper studies cross-lingual semantic similarity (CLSS) between five European languages (i.e. English, French, German, Spanish and Italian) via unsupervised word embeddings from a cross-lingual lexicon. The vocabulary in each language is projected onto a separate high-dimensional vector space, and these vector spaces are then compared using several different distance measures (i.e., correlation, cosine etc.) to measure their pairwise semantic similarities between these languages. A substantial degree of similarity is observed between the vector spaces learned from corpora of the European languages. Null hypothesis testing and bootstrap methods (by resampling without replacement) are utilized to verify the results.
Predictive Incremental Parsing and its Evaluation

For incomplete sentences, different structural descriptions with different levels of prediction are possible. Two existing dependency parsers have been modified to generate sequences of output hypotheses in an incremental manner. The parsing results can be characterized with respect to different criteria like the amount of predicted information, its quality, monotonicity, delay, inclusiveness and connectedness. We propose an evaluation scheme able to capture these properties and apply it to the parsers in different configurations.
Genome Organization and Molecular Analysis of the Temperate Bacteriophage MM1 of Streptococcus pneumoniae

ABSTRACT The genome of MM1 (40,248 bp), a temperate bacteriophage from the Spain23F-1 multiresistant epidemic clone of Streptococcus pneumoniae, is organized in 53 open reading frames (ORFs) and in at least five functional clusters. Bioinformatic and N-terminal amino acid sequence analyses enabled the assignment of possible functions to 26 ORFs. Analyses comparing the MM1 genome with those of other bacteriophages revealed similarities, mainly with genomes of phages infecting gram-positive bacteria, which suggest recent exchange of genes between species colonizing the same habitat.
