Mariners’ physical activity classification at sea using a wrist-worn wearable sensor.

A long-term sea voyage imposes a special living environment on mariners that directly influences their physical health. To our best knowledge, there have been few research efforts that evaluate mariners' physical health during sea life. This study aims to develop wearable-based mariner physical activity classification models. Twenty-eight participants (n=7 females, n=21 males, mean age=21.4, and mean BMI=22.9) wore a single accelerometer on their dominant hand. The wrist acceleration data were collected and analyzed to extract wrist motion features compared to the criterion measures (i.e., direct observation) including four major physical activity types in a maritime setting. Three machine learning algorithms were applied to develop an accurate classification model. The results of the criterion-based classification show that more than 95% of mariners’ daily physical activities were accurately classified. Based on the experimental results, we conclude that the wrist motion features efficiently differentiate major physical activity patterns in a maritime environment. The proposed physical activity classification models can be used as an objective measurement of mariners’ physical activity levels during their long voyage.
BEHAVIOUR OF FIBRE REINFORCE CONCRETE BEAM IN PURE TORSION

It has been observed that a plain concrete member when subjected to cracking torque fails along a spiral inclined at 45 0 to the axis of the member. It is obvious that reinforcement in the form of 45 0 rectangular spirals will be most effective in resisting torque in case of a member of rectangular section. Provision of only longitudinal bars without stirrups increases torsional strength to the extent of 15%, the most appropriate system of torsional reinforcement consists of longitudinal bars together with closed transverse stirrups. In view of above observations, an attempt is made to study the following aspects: Behaviour of reinforced concrete beam under. 1)Pure torsional, (a)Without glass fibres (b)With glass fibres 2)The effect of increase of fibre percentage on torsional resistance of beam. 3) To develop torque. Vs. twist relation of the beams. The experimental program consists of casting 4 reinforced concrete beams of size 150mm X150 mm and length 2m. Two of them were cast without fibres to make a comparative study with the remaining 3 beams; one beam is cast with 0.5% fibre by weight, one beam 1.0% fibre by weight in the rest one beam 1.5% fibre by weight added. The longitudinal reinforcement, spacing of shear stirrups is kept constant.
Anticancer Activity of Toxins from Bee and Snake Venom—An Overview on Ovarian Cancer

Cancer represents the disease of the millennium, a major problem in public health. The proliferation of tumor cells, angiogenesis, and the relationship between the cancer cells and the components of the extracellular matrix are important in the events of carcinogenesis, and these pathways are being used as targets for new anticancer treatments. Various venoms and their toxins have shown possible anticancer effects on human cancer cell lines, providing new perspectives in drug development. In this review, we observed the effects of natural toxins from bee and snake venom and the mechanisms through which they can inhibit the growth and proliferation of cancer cells. We also researched how several types of natural molecules from venom can sensitize ovarian cancer cells to conventional chemotherapy, with many toxins being helpful for developing new anticancer drugs. This approach could improve the efficiency of standard therapies and could allow the administration of decreased doses of chemotherapy. Natural toxins from bee and snake venom could become potential candidates for the future treatment of different types of cancer. It is important to continue these studies concerning therapeutic drugs from natural resource and, more importantly, to investigate their mechanism of action on cancer cells.
Effects of Coyote Population Reduction on Swift Fox Demographics in Southeastern Colorado

Abstract The distribution and abundance of swift foxes (Vulpes velox) has declined from historic levels. Causes for the decline include habitat loss and fragmentation, incidental poisoning, changing land use practices, trapping, and predation by other carnivores. Coyotes (Canis latrans) overlap the geographical distribution of swift foxes, compete for similar resources, and are a significant source of mortality amongst many swift fox populations. Current swift fox conservation and management plans to bolster declining or recovering fox populations may include coyote population reduction to decrease predation. However, the role of coyote predation in swift fox population dynamics is not well-understood. To better understand the interactions of swift foxes and coyotes, we compared swift fox population demographics (survival rates, dispersal rates, reproduction, density) between areas with and without coyote population reduction. On the Piñon Canyon Maneuver Site, Colorado, USA, we monitored 141 swift foxes for 65,226 radio-days from 15 December 1998 to 14 December 2000 with 18,035 total telemetry locations collected. Juvenile swift fox survival rate was increased and survival was temporarily prolonged in the coyote removal area. Adult fox survival patterns were also altered by coyote removal, but only following late-summer coyote removals and, again, only temporarily. Coyote predation remained the main cause of juvenile and adult fox mortality in both areas. The increase in juvenile fox survival in the coyote removal area resulted in a compensatory increase in the juvenile dispersal rate and an earlier pulse in dispersal movements. Adult fox dispersal rate was more consistent throughout the year in the coyote removal area. Coyote removal did not influence the reproductive parameters of the swift foxes. Even though juvenile survival increased, swift fox density remained similar between the areas due to the compensatory dispersal rate among juvenile foxes. We concluded that the swift fox population in the area was saturated. Although coyote predation appeared additive in the juvenile cohort, it was compensatory with dispersal.
Multivariate Dependence Beyond Shannon Information

Accurately determining dependency structure is critical to discovering a system's causal organization. We recently showed that the transfer entropy fails in a key aspect of this---measuring information flow---due to its conflation of dyadic and polyadic relationships. We extend this observation to demonstrate that this is true of all such Shannon information measures when used to analyze multivariate dependencies. This has broad implications, particularly when employing information to express the organization and mechanisms embedded in complex systems, including the burgeoning efforts to combine complex network theory with information theory. Here, we do not suggest that any aspect of information theory is wrong. Rather, the vast majority of its informational measures are simply inadequate for determining the meaningful dependency structure within joint probability distributions. Therefore, such information measures are inadequate for discovering intrinsic causal relations. We close by demonstrating that such distributions exist across an arbitrary set of variables.
Comparative Anatomy of the Bony Labyrinth (Inner Ear) of Placental Mammals

Background Variation is a naturally occurring phenomenon that is observable at all levels of morphology, from anatomical variations of DNA molecules to gross variations between whole organisms. The structure of the otic region is no exception. The present paper documents the broad morphological diversity exhibited by the inner ear region of placental mammals using digital endocasts constructed from high-resolution X-ray computed tomography (CT). Descriptions cover the major placental clades, and linear, angular, and volumetric dimensions are reported. Principal Findings The size of the labyrinth is correlated to the overall body mass of individuals, such that large bodied mammals have absolutely larger labyrinths. The ratio between the average arc radius of curvature of the three semicircular canals and body mass of aquatic species is substantially lower than the ratios of related terrestrial taxa, and the volume percentage of the vestibular apparatus of aquatic mammals tends to be less than that calculated for terrestrial species. Aspects of the bony labyrinth are phylogenetically informative, including vestibular reduction in Cetacea, a tall cochlear spiral in caviomorph rodents, a low position of the plane of the lateral semicircular canal compared to the posterior canal in Cetacea and Carnivora, and a low cochlear aspect ratio in Primatomorpha. Significance The morphological descriptions that are presented add a broad baseline of anatomy of the inner ear across many placental mammal clades, for many of which the structure of the bony labyrinth is largely unknown. The data included here complement the growing body of literature on the physiological and phylogenetic significance of bony labyrinth structures in mammals, and they serve as a source of data for future studies on the evolution and function of the vertebrate ear.
Ionization fraction and the enhanced sulfur chemistry in Barnard 1.

CONTEXT Barnard B1b has revealed as one of the most interesting globules from the chemical and dynamical point of view. It presents a rich molecular chemistry characterized by large abundances of deuterated and complex molecules. Furthermore, it hosts an extremely young Class 0 object and one candidate to First Hydrostatic Core (FHSC) proving the youth of this star forming region. AIMS Our aim is to determine the cosmic ray ionization rate, [Formula: see text], and the depletion factors in this extremely young star forming region. These parameteres determine the dynamical evolution of the core. METHODS We carried out a spectral survey towards Barnard 1b as part of the IRAM Large program ASAI using the IRAM 30-m telescope at Pico Veleta (Spain). This provided a very complete inventory of neutral and ionic C-, N- and S- bearing species with, up to our knowledge, the first secure detections of the deuterated ions DCS+ and DOCO+. We use a state-of-the-art pseudo-time-dependent gas-phase chemical model that includes the ortho and para forms of [Formula: see text] and [Formula: see text] to determine the local value of the cosmic ray ionization rate and the depletion factors. RESULTS Our model assumes n(H2)=105 cm-3 and T k =12 K, as derived from our previous works. The observational data are well fitted with ζH2 between 3×10-17 s-1 and 10-16 s-1, and the following elemental abundances: O/H=3 10-5, N/H=6.4-8 10-5, C/H=1.7 10-5 and S/H between 6.0 10-7 and 1.0 10-6. The large number of neutral/protonated species detected, allows us to derive the elemental abundances and cosmic ray ionization rate simultaneously. Elemental depletions are estimated to be ~10 for C and O, ~1 for N and ~25 for S. CONCLUSIONS Barnard B1b presents similar depletions of C and O than those measured in pre-stellar cores. The depletion of sulfur is higher than that of C and O but not as extreme as in cold cores. In fact, it is similar to the values found in some bipolar outflows, hot cores and photon-dominated regions. Several scenarios are discussed to account for these peculiar abundances. We propose that it is the consequence of the initial conditions (important outflows and enhanced UV fields in the surroundings) and a rapid collapse (~0.1 Myr) that permits to maintain most S- and N-bearing species in gas phase to great optical depths. The interaction of the compact outflow associated with B1b-S with the surrounding material could enhance the abundances of S-bearing molecules, as well.
Determinants of survival in behavioral variant frontotemporal dementia

Background: Behavioral variant frontotemporal dementia (bvFTD) is a common cause of younger onset dementia. Little is known about its rate of progression but a recently identified subgroup seems to have an excellent prognosis. Other determinants of survival are unclear. Methods: We analyzed survival in a large group of clinically diagnosed bvFTD patients (n = 91) with particular attention to demographic and clinical features at presentation. Of the 91 cases, 50 have died, with pathologic confirmation in 28. Results: Median survival in the whole group was 9.0 years from symptom onset, and 5.4 years from diagnosis. After the exclusion of 24 “phenocopy” cases, the analysis was repeated in a subgroup of 67 patients. The mean age at symptom onset of the pathologic group was 58.5 years and 16% had a positive family history. Their median survival was 7.6 years (95% confidence interval [CI] 6.6–8.6) from symptom onset and 4.2 years (95% CI 3.4–5.0) from diagnosis. The only factor associated with shorter survival was the presence of language impairment at diagnosis. Conclusions: Patients with definite frontotemporal dementia have a poor prognosis which is worse if language deficits are also present. This contrasts with the extremely good outcome in those with the phenocopy syndrome: of our 24 patients only 1 has died (of coincident pathology) despite, in some cases, many years of follow-up.
Theory and observations of upward field‐aligned currents at the magnetopause boundary layer

The dependence of the upward field‐aligned current density (J||) at the dayside magnetopause boundary layer is well described by a simple analytic model based on a velocity shear generator. A previous observational survey confirmed that the scaling properties predicted by the analytical model are applicable between 11 and 17 MLT. We utilize the analytic model to predict field‐aligned currents using solar wind and ionospheric parameters and compare with direct observations. The calculated and observed parallel currents are in excellent agreement, suggesting that the model may be useful to infer boundary layer structures. However, near noon, where velocity shear is small, the kinetic pressure gradients and thermal currents, which are not included in the model, could make a small but significant contribution to J||. Excluding data from noon, our least squares fit returns log(J||,max_cal) = (0.96 ± 0.04) log(J||_obs) + (0.03 ± 0.01) where J||,max_cal = calculated J||,max and J||_obs = observed J||.
Moral disagreement and procedural justice: Moral mandates as constraints to voice effects

Abstract Procedural voice is a widely used and effective means to reduce or eliminate conflict. Moral disagreements, however, are particularly inflammatory, divisive, and difficult to manage. The current article reports two studies that demonstrated the unique challenge that moral disagreements pose. Specifically, the studies tested the extent to which procedural voice affected justice judgements, group climate, and decision acceptance when people perceived decisions to have moral implications. Results indicated that when people's outcome preferences represent strong moral convictions, outcomes were the primary determinant of perceived fairness and related judgements, irrespective of whether people had voice in the decision-making process.
Narcissism and self-esteem: Different motivations for selfie posting behaviors

Abstract Over the past few years, social networking site usage has increased rapidly, in particular as concerns photo-sharing and self-portrait photographs (so-called selfies). In the academic literature, some studies have recently analyzed the psychological antecedents of selfie posting behavior to better understand its underlying mechanism. Generally, scholars consider the use of selfies as a means of online self-presentation. In the present research, the effects of two personality traits known to impact self-presentation (i.e. narcissism and self-esteem) are investigated, considering the mediation effects of four selfie posting motives: attention-seeking, communication, archiving, and entertainment. Results on 237 participants show that selfie posting motives, narcissism and self-esteem are differently linked to frequencies depending on the type of selfie posted online (whether own, group, or partner). Moreover, the path analysis model shows that, even if positively correlated between them, self-esteem and narcissism have different motives underlying the use of selfies. In particular, narcissistic people engage in selfie posting behaviors because of a search for the attention of others and the urge to escape from boredom. Contrariwise, these are the two motives for which people with high self-esteem do not get involved in selfie-posting behaviors.
Depression, Hopelessness, and Complicated Grief in Survivors of Suicide

Suicide often has a severe impact on the surviving family and friends. There is a need to better understand the psychological and psychopathological consequences of losing a significant other by suicide. The aim of the present study was to assess hopelessness, depression, suicide risk, complicated grief, intrusive memories, and avoidance in a sample of suicide survivors. In this observational study, 35 bereaved individuals were recruited at the Suicide Prevention Centre of Sant’Andrea Hospital in Rome. Individuals were administered a series of validated instruments: the Beck Depression Inventory II (BDI), the Beck Hopelessness Scale (BHS), the Inventory of Complicated Grief (ICG), the Impact of Event Scale (IES), the Subjective Happiness Scale (SHS), and the Satisfaction With Life Scale (SWLS). Most survivors (62.8%) obtained high scores on measures of complicated grief. Scores on the measure of complicated grief were associated with intrusiveness of thoughts and memories, attempts to prevent the thoughts and emotions related to the event, depressive symptoms and hopelessness, and lower scores for feelings of happiness and satisfaction with life. A subgroup of suicide survivors may be at risk of severe psychological distress and suicidal behavior. Identification of these survivors is a necessary step for providing appropriate counseling and psychotherapy.
Joining Meeting Documents to Strengthen Multimodal Thematic Alignment

A study carried out on multimodal thematic alignment in the context of multi-document meetings is presented in the current paper. First, a classification of documents discussed in meetings is described. The alignment of dialog transcript with discussed documents is then presented based on two different approaches, either combining all documents within one (jointed), or align each document individually with the dialog transcript (disjointed). Furthermore, an entailment process that aims to improve the thematic alignment results is presented. The efficiency of this entailment process is assessed based on the two document arrangement strategies (disjointed/jointed), in addition to other features of discussed document (total/partial discussion and homogeneous/heterogeneous content). An evaluation of the presented techniques over different meeting corpora is then presented. The results tend to prove that the jointed strategy generates better results than the disjointed strategy, for both thematic alignment and entailment process. Moreover, the entailment process might have different effect on the thematic alignment results, depending on the features of the discussed documents.
Impact of Smartphone Position on Sensor Values and Context Discovery

With near-ubiquitous availability of smartphones equipped with a wide variety of sensors, research in building context-aware services has been growing. However, despite a large number of services proposed and developed as research pro-totypes, the number of truly context-aware applications available in smartphone applications market is quite limited. A major barrier for the large-scale proliferation of context aware applications is poor accuracy. This paper addresses one of the key reasons for this poor accuracy, which is the impact of smartphone positions. Users carry their smartphones in different positions such as holding in their hand, keeping inside their pants or jacket pocket, keeping in their purse, and so on. This paper addresses the issue of poor application accuracy due to varying smartphone positions. It ﬁrst shows that smartphone positions signiﬁcantly affect the values of the sensor data being collected by a context aware application, and this in turn has a signiﬁcant impact on the accuracy of the application. Next, it describes the design and prototype development of a smartphone position discovery service that accurately detects a smartphone position. This service is based on the sensor data collected from carefully chosen sensors and runs orthogonal to any other context aware application or service. Finally, the paper demonstrates that the accuracy of an existing context aware service or application is signiﬁcantly enhanced when run in conjunction with the proposed smartphone position discovery service.
Oligoclonal Band Status in Scandinavian Multiple Sclerosis Patients Is Associated with Specific Genetic Risk Alleles

The presence of oligoclonal bands (OCB) in cerebrospinal fluid (CSF) is a typical finding in multiple sclerosis (MS). We applied data from Norwegian, Swedish and Danish (i.e. Scandinavian) MS patients from a genome-wide association study (GWAS) to search for genetic differences in MS relating to OCB status. GWAS data was compared in 1367 OCB positive and 161 OCB negative Scandinavian MS patients, and nine of the most associated SNPs were genotyped for replication in 3403 Scandinavian MS patients. HLA-DRB1 genotypes were analyzed in a subset of the OCB positive (n = 2781) and OCB negative (n = 292) MS patients and compared to 890 healthy controls. Results from the genome-wide analyses showed that single nucleotide polymorphisms (SNPs) from the HLA complex and six other loci were associated to OCB status. In SNPs selected for replication, combined analyses showed genome-wide significant association for two SNPs in the HLA complex; rs3129871 (p = 5.7×10−15) and rs3817963 (p = 5.7×10−10) correlating with the HLA-DRB1*15 and the HLA-DRB1*04 alleles, respectively. We also found suggestive association to one SNP in the Calsyntenin-2 gene (p = 8.83×10−7). In HLA-DRB1 analyses HLA-DRB1*15∶01 was a stronger risk factor for OCB positive than OCB negative MS, whereas HLA-DRB1*04∶04 was associated with increased risk of OCB negative MS and reduced risk of OCB positive MS. Protective effects of HLA-DRB1*01∶01 and HLA-DRB1*07∶01 were detected in both groups. The groups were different with regard to age at onset (AAO), MS outcome measures and gender. This study confirms both shared and distinct genetic risk for MS subtypes in the Scandinavian population defined by OCB status and indicates different clinical characteristics between the groups. This suggests differences in disease mechanisms between OCB negative and OCB positive MS with implications for patient management, which need to be further studied.
