CloudIntell: An intelligent malware detection system

Enterprises and individual users heavily rely on the abilities of antiviruses and other security mechanisms. However, the methodologies used by such software are not enough to detect and prevent most of the malicious activities and also consume a huge amount of resources of the host machine for their regular operations. In this paper, we propose a combination of machine learning techniques applied on a rich set of features extracted from a large dataset of benign and malicious files through a bespoke feature extraction tool. We extracted a rich set of features from each file and applied support vector machine, decision tree, and boosting on decision tree to get the highest possible detection rate. We also introduce a cloud-based scalable architecture hosted on Amazon web services to cater the needs of detection methodology. We tested our methodology against different scenarios and generated high achieving results with lowest energy consumption of the host machine.

A SoxB gene acts as an anterior gap gene and regulates posterior segment addition in a spider

Sox genes encode a set of highly conserved transcription factors that regulate many developmental processes. In insects, the SoxB gene Dichaete is the only Sox gene known to be involved in segmentation. To determine if similar mechanisms are used in other arthropods, we investigated the role of Sox genes during segmentation in the spider Parasteatoda tepidariorum. While Dichaete does not appear to be involved in spider segmentation, we found that the closely related Sox21b-1 gene acts as a gap gene during formation of anterior segments and is also part of the segmentation clock for development of the segment addition zone and sequential addition of opisthosomal segments. Thus, we have found that two different mechanisms of segmentation in a non-mandibulate arthropod are regulated by a SoxB gene. Our work provides new insights into the function of an important and conserved gene family, and the evolution of the regulation of segmentation in arthropods.

Does forest management and researchers’ presence reduce hunting and forest exploitation by local communities in Tsitongambarika, south-east Madagascar?

Hunting of wildlife is one of the major threats to biodiversity. For effective conservation programmes in countries where hunting and shifting agriculture are the main sources of subsistence, forest management should aim to reduce hunting pressure and forest exploitation. The presence of researchers has been promoted as one of the main ways to mitigate anthropogenic pressures on wildlife populations. Our aim was to test whether local management and the establishment of a research station had a role in decreasing forest exploitation by local people living adjacent to a recently protected area in south-east Madagascar. We interviewed local people from nine villages at various distances from the recently established research station of Ampasy, in the northernmost portion of the Tsitongambarika Protected Area, to explore how people use the forest, with a particular focus on hunting. We also performed transect surveys to estimate snare and lemur encounter rates before local forest management began, at the establis…

Emotional intelligence, alexithymia, stress and peoples’ reasons for listening to music

The present study investigated the relationship between people’s reasons for listening to music, trait emotional intelligence and alexithymia whilst also controlling for the effect of participants’ gender, age and perceived stress levels. In keeping with previous research, initial findings indicated that emotionally intelligent individuals were less likely to use music to relieve and alleviate negative moods, whilst those who had high scores on a measure of alexithymia were more likely to use music for the same reasons. However, when the effects of gender, age and perceived stress were controlled for these relationships were no longer significant and previously non-significant relationships between trait emotional intelligence and using music to manipulate arousal and to reminisce about the past were found to be significant. Together these findings suggest that emotional intelligence is related to the reasons why people listen to music but not in the way that previous research had suggested, and the apparent …

The experiences of gay and bisexual men post-prostate cancer treatment: a meta-synthesis of qualitative studies

Studies suggest that gay and bisexual men are affected by the psychological aspects of prostate cancer treatment differently than that of heterosexual men, however the data have not yet been synthesized. The focus of this meta-synthesis is to explore gay and bisexual men’s experiences of prostate cancer post-treatment. Empirical research published in peer reviewed journals between January 1990 and January 2018 were identified in six databases: CINAHL, Cochrane, Medline, PsycINFO, PubMed, and Web of Science. Titles and abstracts were checked by two reviewers. The six studies that met the inclusion criteria were selected and reviewed for quality and the extracted data were then synthesized. The main themes that emerged were sexual impact, physical and psychological difficulties, challenges to intimacy, and support mechanisms. Gay and bisexual men can have specific sexual roles and developing prostate cancer and undergoing treatment may compromise their ability to perform their sexual role. The needs of heterose…

Gene regulatory network architecture in different developmental contexts influences the genetic basis of morphological evolution

Convergent phenotypic evolution is often caused by recurrent changes at particular nodes in the underlying gene regulatory networks (GRNs). The genes at such evolutionary ‘hotspots’ are thought to maximally affect the phenotype with minimal pleiotropic consequences. This has led to the suggestion that if a GRN is understood in sufficient detail, the path of evolution may be predictable. The repeated evolutionary loss of larval trichomes among Drosophila species is caused by the loss of shavenbaby (svb) expression. svb is also required for development of leg trichomes, but the evolutionary gain of trichomes in the ‘naked valley’ on T2 femurs in Drosophila melanogaster is caused by the loss of microRNA-92a (miR-92a) expression rather than changes in svb. We compared the expression and function of components between the larval and leg trichome GRNs to investigate why the genetic basis of trichome pattern evolution differs in these developmental contexts. We found key differences between the two networks in both …

How many patients in a prolonged disorder of consciousness might need a best interests meeting about starting or continuing gastrostomy feeding?

Objective. To estimate the number of people in a prolonged disorder of consciousness (PDOC) who may need a formal best interests decision-making process to consider starting and/or continuing life-sustaining treatment each year in the population of a developed country. Method. Identification of studies on people with a prolonged disorder of consciousness giving information about incidence, and/or prevalence, and/or cause ,and/or location of long-term care. Sources included systematic reviews, a new search of Medline (April 2018), and a personal collection of papers. Validating information was sought from existing data on services. Results. There are few epidemiologically sound studies, most having bias and/or missing information. The best estimate of incidence of PDOC due to acute-onset disease is 2.6/100,000/year; the best estimate of prevalence is between 2.0 and 5.0/100,000. There is evidence that prevalence in the Netherlands is about 10% of that in other countries. The commonest documented causes are cer…

The use of a Facebook group to enhance student recruitment and the student experience: A cohort study

Universities routinely use Facebook as a marketing tool, but little is known about its impact on recruitment or the student experience. The current study evaluated the development of a subject-specific Facebook group for students at Oxford Brookes University (OBU). It was expected that creating a sense of connectedness among potential students and with the university through a Facebook group would help them to decide to accept their offer of a place to study and have a positive impact on their experience of OBU. A cohort of 116 first year students, who had been offered a place to study a health and social care subject, were invited to become members of the Facebook group. Sixty-three students became members. Subsequently, students who joined the University in September completed a survey to assess their perceptions of belonging or not belonging to the Facebook group. In support of the hypothesis, there was a significant association between Facebook group membership and accepting an offer to study at OBU: 59% …

Association between gait and cognition in an elderly population based sample

Background. Gait is thought to have a cognitive component, but the current evidence in healthy elderly is mixed. We studied the association between multiple gait and cognitive measures in a cohort of older people. Methods. 178 cognitively healthy participants from the Whitehall II Imaging Sub-study had a detailed clinical and neuropsychological assessment, as well as a MRI scan. Spatiotemporal and variability gait measures were derived from two 10m walks at self-selected speed. We did a linear regression analysis, entering potential confounders with backwards elimination of variables with p≥0.1.The remaining variables were then entered into a second regression before doing a stepwise analysis of cognitive measures, entering variables with p<0.05 and removing those with p≥0.1. Results. Amongst absolute gait measures, only greater stride length was associated with better performance in the TMT A and the BNT. The STV was associated with performance in the TMT A. Age was associated with poorer walking speed and s…
