Mobile hotspots cooperation towards better energy efficiency

Power consumption from wireless data communications contributes a significant part for the overall mobile phone platform power. Compared with cellular data transmission, Wi-Fi transmission is more energy-efficient. Nevertheless, there are scenarios where cellular network is the only option to access the Internet for a number of mobile phones because of limited Wi-Fi access. This paper proposes a cooperative approach of using Wi-Fi tethering technique to optimize the overall power consumption. Based on a series of real measurements, we characterize the relationship among signal strength, network bandwidth and power consumption, and point out principles of choosing appropriate mobile hotspot nodes. Then we propose two cooperative algorithms to optimize the overall power consumption, i.e., most suitable hotspot first (MSHF) and most suitable leaf first (MSLF). Simulation results demonstrate that MSHF can acquire 24% power saving and MSLF can achieve up to 29% compared with regular 3G approach.
Modeling fatty acid delivery from intestinal fatty acid binding protein to a membrane

Intestinal fatty acid binding protein (IFABP) interacts with biological membranes and delivers fatty acid (FA) into them via a collisional mechanism. However, the membrane‐bound structure of the protein and the pathway of FA transfer are not precisely known. We used molecular dynamics (MD) simulations with an implicit membrane model to determine the optimal orientation of apo‐ and holo‐IFABP (bound with palmitate) on an anionic membrane. In this orientation, the helical portal region, delimited by the αII helix and the βC‐βD and βE‐βF turns, is oriented toward the membrane whereas the putative β‐strand portal, delimited by the βB‐βC, βF‐βG, βH‐βI turns and the N terminus, is exposed to solvent. Starting from the MD structure of holo‐IFABP in the optimal orientation relative to the membrane, we examined the release of palmitate via both pathways. Although the domains can widen enough to allow the passage of palmitate, fatty acid release through the helical portal region incurs smaller conformational changes and a lower energetic cost.
On properties of the Ising model for complex energy/temperature and magnetic field

We study some properties of the Ising model in the plane of the complex (energy/temperature)-dependent variable u = e−4K, where K = J/(kBT), for nonzero external magnetic field, H. Exact results are given for the phase diagram in the u plane for the model in one dimension and on infinite-length quasi-one-dimensional strips. In the case of real h = H/(kBT), these results provide new insights into features of our earlier study of this case. We also consider complex h = H/(kBT) and μ = e−2h. Calculations of complex-u zeros of the partition function on sections of the square lattice are presented. For the case of imaginary h, i.e., μ = eiθ, we use exact results for the quasi-1D strips together with these partition function zeros for the model in 2D to infer some properties of the resultant phase diagram in the u plane. We find that in this case, the phase boundary contains a real line segment extending through part of the physical ferromagnetic interval 0 ⩽ u ⩽ 1, with a right-hand endpoint urhe at the temperature for which the Yang–Lee edge singularity occurs at μ = e±iθ. Conformal field theory arguments are used to relate the singularities at urhe and the Yang–Lee edge.
Bystander Behavior Intervention in Risky Sexual Assault Situations: An Examination of Social Norms and Situational Factors

Wyatt, Joel D. , M.S., December 2016, Psychology Bystander Behavior Intervention in Risky Sexual Assault Situations: An Examination of Social Norms and Situational Factors Director of Thesis: Christine A. Gidycz Sexual assault is a well-documented problem on college campuses. One way to prevent sexual assault is for bystanders to intervene, and social norms theory posits that an individual’s decision to intervene in a risky situation is influenced by perceived peer norms and situational factors (e.g., alcohol consumption, riskiness for the victim, knowing the potential victim). Previous research has provided evidence that perceived peer norms are associated with whether or not bystanders decide to intervene in risky situations, but these studies have been limited by typically using measures to assess bystander behavior that do not account for whether an individual has an opportunity to intervene. Further, many of the situational variables that have been examined have been limited in that they have been dichotomized when the construct that is being measured is inherently continuous (e.g., relationship with a potential victim). The purpose of this study is to predict bystander intervention using a set of social norm variables (perception of peers’ rape myth acceptance, prosocial tendencies and hypergender ideology) and individual-level variables in a sample of college men and women, as well as examine situational-specific variables at the time of an event. Perceptions of peer norms were unrelated to bystander behavior; however, perceived impact of alcohol use, perceived risk for a bystander, perceived closeness to a potential victim and previous intervention were related to bystander behavior. Implications of the findings are discussed.
Regeneration patterns and persistence of the fog‐dependent Fray Jorge forest in semiarid Chile during the past two centuries

The persistence of rainforest patches at Fray Jorge National Park (FJNP) in semiarid Chile (30°40′S), a region receiving approximately 147 mm of annual rainfall, has been a source of concern among forest managers. These forests are likely dependent on water inputs from oceanic fog and their persistence seems uncertain in the face of climate change. Here, we assessed tree radial growth and establishment during the last two centuries and their relation to trends in climate and canopy disturbance. Such evaluation is critical to understanding the dynamics of these semiarid ecosystems in response to climate change. We analyzed forest structure of six forest patches (0.2–22 ha) in FJNP based on sampling within 0.1 ha permanent plots. For the main canopy species, the endemic Aextoxicon punctatum (Aextoxicaceae), we used tree‐ring analysis to assess establishment periods, tree ages, growing trends and their relation to El Niño Southern Oscillation (ENSO), rainfall, and disturbance. The population dynamics of A. punctatum can be described by a continuous regeneration mode. Regeneration of A. punctatum was sensitive to different canopy structures. Growth release patterns suggest the absence of large scale human impact. Radial growth and establishment of A. punctatum were weakly correlated with rainfall and ENSO. If water limits forests patch persistence, patches are likely dependent on the combination of fog and rain water inputs. Forest patches have regenerated continuously for at least 250 years, despite large fluctuations in rainfall driven by ENSO and a regional decline in rainfall during the last century. Because of the positive influence on fog interception, forest structure should be preserved under any future climate scenario. Future research in FJNP should prioritize quantifying the long‐term trends of fog water deposition on forests patches. Fog modeling is crucial for understanding the interplay among physical drivers of water inputs under climate change.
Young children’s appreciation and production of verbal and visual humor

Abstract This study aimed to investigate young children’s ability to appreciate and produce humor. Specifically the research questions were: 1. What aspects of a humorous visual stimulus do children of the ages 4–7 years appreciate and why? 2. What are the differences, if any, in producing a humorous story and a drawing? Are these related to creativity variables? 3. How are children’s appreciation and production of visual humor related to the Theory of the Absurd and the Empowerment theory (Loizou 2005, Infant humor: The theory of the absurd and the empowerment theory. International Journal of Early Years Education 13(1). 43–53)? The participants of this study were 102 children of the ages 3–7. During semi-structured interviews children were asked to observe and comment on the funniness of a picture, produce a funny story and then to make a funny drawing. Both qualitative and quantitative methods were used to analyze the data. The findings suggest that a. as a research tool, the use of a picture that represents a child acting “dangerously” can affect children’s reaction to humor b. in the production of a humorous drawing children use mainly the Incongruity theory whereas in their story production they use the Empowerment theory and c. the cognitive schemata used in explaining the humorous part in their story and drawing are different.
Cell Search Procedures in LTE Systems

In this paper, we present a cell search procedure for a Long Term Evolution (LTE) system based device, which involves determining the primary group identifier associated with a cell as well as its timing information. This is facilitated by using the primary synchronization signal available in an LTE system. For the first stage of cell search, this paper presents a time-domain based cell search procedure in an LTE system. Further, we evaluate the performance of such an approach with varying levels of noise and present the design considerations to be utilized in developing a searcher hardware block. We also present analytical and simulation results to evaluate the searcher performance.
Developing an is-impact decision tool: a literature based design science roadmap

This paper derives from research-in-progress intending both Design Research (DR) and Design Science (DS) outputs; the former a management decision tool based in IS-Impact (Gable et al. 2008) kernel theory; the latter being methodological learnings deriving from synthesis of the literature and reflection on the DR ‘case study’ experience. The paper introduces a generic, detailed and pragmatic DS ‘Research Roadmap’ or methodology, deriving at this stage primarily from synthesis and harmonization of relevant concepts identified through systematic archival analysis of related literature. The scope of the Roadmap too has been influenced by the parallel study aim to undertake DR applying and further evolving the Roadmap. The Roadmap is presented in attention to the dearth of detailed guidance available to novice Researchers in Design Science Research (DSR), and though preliminary, is expected to evolve and gradually be substantiated through experience of its application. A key distinction of the Roadmap from other DSR methods is its breadth of coverage of published DSR concepts and activities; its detail and scope. It represents a useful synthesis and integration of otherwise highly disparate DSR-related concepts.
Bow Your Head in Shame, or, Hold Your Head Up with Pride: Semantic Processing of Self-Esteem Concepts Orients Attention Vertically

Embodied cognition holds that abstract concepts are grounded in perceptual-motor simulations. If a given embodied metaphor maps onto a spatial representation, then thinking of that concept should bias the allocation of attention. In this study, we used positive and negative self-esteem words to examine two properties of conceptual cueing. First, we tested the orientation-specificity hypothesis, which predicts that conceptual cues should selectively activate certain spatial axes (in this case, valenced self-esteem concepts should activate vertical space), instead of any spatial continuum. Second, we tested whether conceptual cueing requires semantic processing, or if it can be achieved with shallow visual processing of the cue words. Participants viewed centrally presented words consisting of high or low self-esteem traits (e.g., brave, timid) before detecting a target above or below the cue in the vertical condition, or on the left or right of the word in the horizontal condition. Participants were faster to detect targets when their location was compatible with the valence of the word cues, but only in the vertical condition. Moreover, this effect was observed when participants processed the semantics of the word, but not when processing its orthography. The results show that conceptual cueing by spatial metaphors is orientation-specific, and that an explicit consideration of the word cues’ semantics is required for conceptual cueing to occur.
Optical follow-up of new Small Magellanic Cloud wing Be/X-ray binaries

We investigate the optical counterparts of recently discovered Be/X-ray binaries in the Small Magellanic Cloud (SMC). In total four sources, SXP101, SXP700, SXP348 and SXP65.8 were detected during the Chandra survey of the wing of the SMC. SXP700 and SXP65.8 were previously unknown. Many optical ground-based telescopes have been utilized in the optical follow-up, providing coverage in both the red and blue bands. This has led to the classification of all of the counterparts as Be stars and confirms that three lie within the Galactic spectral distribution of known Be/X-ray binaries. SXP101 lies outside this distribution and is the latest spectral type known. Monitoring of the Ha emission line suggests that all the sources barring SXP700 have highly variable circumstellar discs, possibly a result of their comparatively short orbital periods. Phase-resolved X-ray spectroscopy has also been performed on SXP65.8, revealing that the emission is indeed harder during the passage of the X-ray beam through the line of sight.

Diagnostic Workup for Disorders of Bone and Mineral Metabolism in Patients with Chronic Kidney Disease in the Era of KDIGO Guidelines

KDIGO (Kidney Disease: Improving Global Outcomes) is an international nonprofit organization devoted to “improve the care and outcomes of kidney disease patients worldwide through promoting coordination, collaboration, and integration of initiatives to develop and implement clinical practice guidelines. ” The mineral and bone disorder (MBD) in patients with chronic kidney disease (CKD) has been the first area of interest of KDIGO international initiative. KDIGO guidelines on CKD-MBD were published in 2009 with the intent to modify the previous KDOQI guidelines that had failed to consistently change the global outcome of CKD patients. After the publication of KDOQI guidelines for bone metabolism and disease in 2003, a large number of observational data emerged in literature linking disordered mineral metabolism with adverse clinical outcomes. Notwithstanding this large body of observational data, a paucity of evidence from high-quality clinical trials was available for the development of KDIGO guidelines. Herein, a summary will be provided of the most important findings of KDIGO guidelines regarding the diagnostic workup and clinical monitoring of CKD-MBD patients.
A corpus-based approach to Information Extraction

This paper presents an Information Extraction (IE) system. This kind of system is intended to extract structured information from general texts. An evaluation is performed and the results are discussed. We show that, i f IE is now an establi shed technology, it suffers a number of limit ations that prevent its dissemination through general publi c appli cations. To get over this obstacle, systems have to acquire domain-specific extraction patterns. This task makes IE being related to knowledge acquisiti on and corpus li nguistics. We present the European ECRAN project and make some original proposals impli cating Topic Detection, Lexical Tuning and Intelli gent Interfaces in this framework. We show that an interaction is necessary between these different components and the end-user in order to incrementall y increase the overall performances of the system.
The Predictors of Career Success

This study was carried out to examine the relationship between career commitment, career values perceived organizational support (POS) and career success. Using convenient sampling, data was gathered using 291 questionnaires. Correlation and regression analysis were performed to determine the significance of the independent variables, career values and POS on career success. Analysis of the data revealed that career commitment, career values and POS have significant but moderate relationship with career success. The findings show that variables, that is, career commitment, career values and POS influence approximately 61% variance on career success. This means there other factors that could not be explained by this study that determine career success. Future research should look at other variables such as human capital, socio-demographic status and stable individual difference that might influence career success
Longitudinal Examination of the State-Like Motivational Processes Linking Ability and Dispositional Self-Efficacy to Training Effectiveness

STANHOPE, DANIEL STERLING. Longitudinal Examination of the State-Like Motivational Processes Linking Ability and Dispositional Self-Efficacy to Training Effectiveness. (Under the direction of Samuel B. Pond III.) Research on training effectiveness helps individuals, groups, and organizations benefit from this ubiquitous human resource development activity. Using longitudinal data (N = 1459) from a military training context, I employ multivariate latent growth modeling (LGM) to examine the impact of trait-like individual differences on learning outcomes through state-like intervening processes. Contrary to the common practice of collecting data on the mediator(s) on a single occasion, I measure mediators on multiple occasions, which allows for a more nuanced elucidation of the explanatory role played by motivational processes. I conduct a 3-step procedure that involves (a) modeling mediators (i.e., specific self-efficacy and self-set goals) as latent growth factors across 3 time points, (b) examining time-invariant predictors (i.e., ability and dispositional self-efficacy) of the latent growth factors, and (c) examining outcomes (i.e., cognitive, affective, and skill-based learning) of the latent growth factors. Results suggest the motivational process develops linearly and that interindividual variability exists in both starting values and growth rates for the process variables. Further, ability and dispositional self-efficacy relate differently to the latent growth factors and demonstrate both direct effects on learning and indirect effects on learning through the mediating motivational growth process. Results have scientific implications—for instance, examining intervening mechanisms with LGM allows one to better expose the “black-box” processes that occur between dispositional influence and training outcomes; results also have practical implications—for instance, better understanding the growth process informs formative evaluation efforts, provides trainers with actionable diagnostic information, and may inform the utility of training interventions.

The significance of DNA damage, its repair and cell proliferation during carcinogen treatment in the initiation of pancreatic cancer in the hamster model.

N-Nitroso(2-hydroxypropyl)(2-oxopropyl)amine (HPOP) is a complete pancreatic carcinogen in female hamsters at a dose of 210 mg/kg given via an Alzet 2001 pump implanted s.c. Ultimate carcinogenic metabolites of HPOP target DNA to yield 7-and O6-methylguanines (7-mGua, O6-mGua) and 7- and O6-hydroxypropylguanines (7-HpGua, O6-HpGua). During continuous administration of HPOP, levels of DNA alkylation increase linearly with time of exposure and reach a maximum at the end of treatment. Such levels are markedly lower in pancreas or in its component duct or acinar cells than in liver or in other extrahepatic organs examined, indicating that the organotropy of HPOP does not directly correlate to its extent of activation by various tissues. After continuous treatment with HPOP, all major DNA adducts with the exception of 7-mGua in liver are repaired at rates slower than those measured after a single injection of the carcinogen. Half-lives for the repair of O6-mGua are 240 h in liver and considerably longer in extrahepatic tissues. Half-lives for the removal of 7-mGua are 46, 55, 72, and 96 h in liver, kidney, lung, and pancreas; while respective values for 7-HpGua are 216, 216, 132, and 140 h. No significant repair is observed for O6-HpGua for at least 8 days. The above differences in half-lives result in the gradual increase of 7-HpGua and O6-HpGua relative to their methyl counterparts. DNA synthesis progressively increases during HPOP infusion in all the tissues examined, and reaches maximum levels 3 to 4 days after termination of treatment. In pancreas, such levels are up to 5 times greater in HPOP treated animals than in controls. The increase in DNA synthesis during carcinogen treatment is due to the greater number of cells entering S phase rather than to an increase in the rate of proliferation of a certain population of cells. The mitogenic effect of HPOP in the pancreas and the persistence of highly promutagenic hydroxypropyl adducts are postulated to contribute to the initiation of pancreatic cancer in the hamster model.
