Authors: Redondo Alberto , Insua David Ríos 
Published: July 2020

AbstractMalware constitutes a major global risk affecting millions of users each year. Standard algorithms in detection systems perform insufficiently when dealing with malware passed through obfuscation tools. We illustrate this studying in detail an open source metamorphic software, making use of a hybrid framework to obtain the relevant features from binaries. We then provide an improved alternative solution based on adversarial risk analysis which we illustrate describe with an example.
The meaning of significant encounters in forensic care
Authors: Rytterström Patrik , Rydenlund Kenneth , Ranheim Albertine 
Published: July 2020

AbstractBackgroundResearch in forensic psychiatric care focusing on person‐oriented care is ambiguous about matters of quality. The encounters between a healthcare professional (HCP) and patient could influence how connections and relations emerge between the caregiver and the patient.ObjectivesTo better understand caring aspects, this study explores significant encounters in forensic psychiatric care from the perspective of HCPs.MethodThis study is based on 34 written narratives from HCPs from two forensic psychiatric hospitals in Sweden. The narratives concern significant encounters with a patient. These narratives were analysed according to methodologies developed by phenomenological and reflective lifeworld research.FindingsThe essence of a significant encounter is a temporal extended phenomenon that both precedes as well as is a consequence of the actual encounter as it occurs. The encounter is unforeseeable and being open to an encounter also means to be vulnerable as it is not predetermined how someone will respond. The significant encounter is an act of sharing, and HCPs may come to understand more about their patients as well as about themselves. Moreover, these encounters seem to create repercussions and hope for the future care.ConclusionsThe everyday activities of forensic psychiatric care are not trivial activities. Rather, they are important aspects of health care as these everyday encounters can deepen the relationship between the HCPs and their patients and help both the HCPs and their patients develop a sense of hope for the future.

Abstract
Laser machining is an inexpensive and fast alternative to conventional microfabrication techniques and has the capability to produce complicated three-dimensional (3D), hierarchical structures. It is especially important while performing rapid prototyping and quick design studies of extreme heat flux cooling devices. One of the major issues plaguing the use of laser micromachining to manufacture commercially usable devices, is the formation of debris during cutting and the difficulty in removing these debris efficiently after the machining process. For silicon substrates, this debris can interfere with surrounding components and cause problems during bonding with other substrates by preventing uniform conformal contact. This study delves deep into the challenges faced and methods to overcome them during laser micromachining-based manufacturing of such complicated 3D-manifolded microcooler structures. Specifically, this work summarizes several postprocess techniques that can be employed for complete debris removal during etching of silicon samples using an Nd/YVO4 ultraviolet (UV) laser, detailing the advantages and drawbacks of each approach. A method that was found to be particularly promising to achieve very smooth surfaces with almost complete debris removal was the use of polydimethylsiloxane (PDMS) as a high-rigidity protective coating. In the process, a novel technique to strip PDMS from silicon surface was also developed. The result of this study is valuable to the microfabrication industry where smooth and clean substrate surfaces are highly desirable and it will significantly improve the process of using UV lasers to create microstructures for commercial applications as well as in a research environment.

Published: July 2020

Abstract
This article proposes a new hybrid least squares-support vector machine and artificial bee colony algorithm (ABC-LS-SVM) for multi-hour ahead forecasting of global solar radiation (GHI) data. The framework performs on training the least squares-support vector machine (LS-SVM) model by means of the ABC algorithm using the measured data. ABC is developed for free parameters optimization for the LS-SVM model in a search space so as to boost the forecasting performance. The developed ABC-LS-SVM approach is verified on an hourly scale on a database of five years of measurements. The measured data were collected from 2013 to 2017 at the Applied Research Unit for Renewable Energy (URAER) in Ghardaia, south of Algeria. Several combinations of input data have been tested to model the desired output. Forecasting results of 12 h ahead GHI with the ABC-LS-SVM model led to the root-mean-square error (RMSE) equal to 116.22 Wh/m2, Correlation coefficient r = 94.3%. With the classical LS-SVM, the RMSE error equals to 117.73 Wh/m2 and correlation coefficient r = 92.42%; for cuckoo search algorithm combined with LS-SVM, the RMSE = 116.89 Wh/m2 and r = 93.78%. The results achieved reveal that the proposed hybridization scheme provides a more accurate performance compared to cuckoo search-LS-SVM and the stand-alone LS-SVM.
Mapping of Wear Mechanism for Mechanical Alloyed Aluminum Carbon Nanotube Composites—An In Situ Analysis
Authors: Manikandan P. , Elaya Perumal A. , Franklin Issac R. 
Published: July 2020

AbstractThis research work investigates the root causes of wear on the tribo surface of mechanically alloyed Aluminum/CNT composite through a simulated in situ analysis. The wear maps are developed using the second-order polynomial regression equation for the Aluminum/CNT composite to discriminate the wear mechanisms at different levels of their influencing factors and milling parameters. As a result, the predominant wear mechanism is identified as surface fatigue for Aluminum/CNT composite under high loading dry sliding condition. This study also reveals the modes for eliminating the severe wear at the tribo-surfaces. Aluminum/CNT1 wt% composite fabricated with the mechanical alloying parameters above 6 h of milling time and above 5 rps of milling speed eliminates the delamination under low level of tribological parameters, and it achieves the minimal wear-rate of 30.5 × 10−6 g/m and coefficient of friction (CoF) of 0.346.
Mechanics Strategies for Implantation of Flexible Neural Probes
Authors: Zhang Shun , Wang Chengjun , Linghu Changhong , Wang Suhao , Song Jizhou 
Published: July 2020

AbstractFlexible polymer-based neural probes are promising tools to interfaces with brain tissue since the low stiffness and thin geometry of these probes make them compliant to soft tissue in a manner that allows for reducing the inflammation responses. However, the same properties make flexible probes susceptible to bending and buckling during insertion, which make the implantation impossible. This paper provides a brief review of recent advances in mechanics strategies to assist the insertion of flexible probes. The basic concept of each strategy is summarized with advantages and disadvantages briefly discussed. These results provide a guide for reliable implantations of flexible neural probes for chronic brain electrophysiological recording and clinical treatment of neurological disorders.
Dune-scale cross-strata across the fluvial-deltaic backwater regime: Preservation potential of an autogenic stratigraphic signature

Published: July 2020

Abstract
Dune-scale cross-beds are a fundamental building block of fluvial-deltaic stratigraphy and have been recognized on Earth and other terrestrial planets. The architecture of these stratal elements reflects bed-form dynamics that are dependent on river hydrodynamic conditions, and previous work has documented a multitude of scaling relationships to describe the morphodynamic interactions between dunes and fluid flow. However, these relationships are predicated on normal flow conditions for river systems and thus may be unsuitable for application in fluvial-deltaic settings that are impacted by nonuniform flow. The ways in which dune dimensions vary systematically due to the influence of reach-averaged, nonuniform flow, and how such changes may be encoded in dune cross-strata, have not been investigated. Herein, we explored the influence of backwater flow on dune geometry in a large modern fluvial channel and its implications for interpretation of systematic variability in dune cross-strata in outcrop-scale stratigraphy. This was accomplished by analyzing high-resolution channel-bed topography data for the lowermost 410 km of the Mississippi River, which revealed that dune size increases to a maximum before decreasing toward the river outlet. This spatial variability coincides with enhanced channel-bed aggradation and decreasing dune celerity, which arise due to backwater hydrodynamics. An analytical model of bed-form stratification, identifying spatial variability of cross-set thickness, indicates a prominent downstream decrease over the backwater region. These findings can be used to inform studies of ancient fluvial-deltaic settings, by bolstering assessments of proximity to the marine terminus and associated spatially varying paleohydraulics.

BackgroundIt is essential to provide comprehensive sexual and reproductive health (SRH) interventions to women affected by armed conflict, but there is a lack of evidence on effective approaches to delivering such interventions in conflict settings. This review synthesised the available literature on SRH intervention delivery in conflict settings to inform potential priorities for further research and additional guidance development.MethodsWe searched MEDLINE, Embase, CINAHL and PsycINFO databases using terms related to conflict, women and children, and SRH. We searched websites of 10 humanitarian organisations for relevant grey literature. Publications reporting on conflict-affected populations in low-income and middle-income countries and describing an SRH intervention delivered during or within 5 years after the end of a conflict were included. Information on population, intervention and delivery characteristics were extracted and narratively synthesised. Quantitative data on intervention coverage and effectiveness were tabulated, but no meta-analysis was undertaken.Results110 publications met our eligibility criteria. Most focused on sub-Saharan Africa and displaced populations based in camps. Reported interventions targeted family planning, HIV/STIs, gender-based violence and general SRH. Most interventions were delivered in hospitals and clinics by doctors and nurses. Delivery barriers included security, population movement and lack of skilled health staff. Multistakeholder collaboration, community engagement and use of community and outreach workers were delivery facilitators. Reporting of intervention coverage or effectiveness data was limited.DiscussionThere is limited relevant literature on adolescents or out-of-camp populations and few publications reported on the use of existing guidance such as the Minimal Initial Services Package. More interventions for gender-based violence were reported in the grey than the indexed literature, suggesting limited formal research in this area. Engaging affected communities and using community-based sites and personnel are important, but more research is needed on how best to reach underserved populations and to implement community-based approaches.PROSPERO registration numberCRD42019125221.

Published: July 2020

ObjectivesPrimary Care Networks (PCNs) are a new organisational hierarchy with wide-ranging responsibilities introduced in the National Health Service (NHS) Long Term Plan. The vision is that PCNs should represent ‘natural’ communities of general practices (GP practices) collaborating at scale and covering a geography that fits well with practices, other healthcare providers and local communities. Our study aims to identify natural communities of GP practices based on patient registration patterns using Markov Multiscale Community Detection, an unsupervised network-based clustering technique to create catchments for these communities.DesignRetrospective observational study using Hospital Episode Statistics - patient-level administrative records of attendances to hospital.SettingGeneral practices in the 32 Clinical Commissioning Groups of Greater LondonParticipantsAll adult patients resident in and registered to a GP practice in Greater London that had one or more outpatient encounters at NHS hospitals between 1st April 2017 and 31st March 2018.Main outcome measuresThe allocation of GP practices in Greater London to PCNs based on the registrations of patients resident in each Lower Layer Super Output Area (LSOA) of Greater London. The population size and coverage of each proposed PCN.Results3 428 322 unique patients attended 1334 GPs in 4835 LSOAs in Greater London. Our model grouped 1291 GPs (96.8%) and 4721 LSOAs (97.6%) into 165 mutually exclusive PCNs. Median PCN list size was 53 490, with a lower quartile of 38 079 patients and an upper quartile of 72 982 patients. A median of 70.1% of patients attended a GP within their allocated PCN, ranging from 44.6% to 91.4%.ConclusionsWith PCNs expected to take a role in population health management and with community providers expected to reconfigure around them, it is vital to recognise how PCNs represent their communities. Our method may be used by policymakers to understand the populations and geography shared between networks.
Risk factors for delirium among older adults in the emergency department: a systematic review protocol
Authors: Oliveira J e Silva Lucas , Berning Michelle J , Stanich Jessica A , Gerberi Danielle J , Han Jin , Bellolio Fernanda 
Published: July 2020

IntroductionDelirium is commonly missed in older adults presenting to the emergency department (ED). Although current recommendations for active screening of delirium in the ED, this might not be feasible or practical. Identifying patients at high risk for prevalent and incident delirium in the ED will help to improve the screening process and to build interventions. There is currently scattered synthesis of evidence on risk factors associated with delirium in the ED. To address this gap, we are conducting a systematic review to describe the risk factors (patient vulnerability factors and precipitating factors) for delirium in the ED.Methods and analysisA literature search was performed from inception to March 2020 in Ovid EBM Reviews, Ovid EMBASE, Ovid MEDLINE, Scopus and Web of Science. We will include original research studies that report a quantitative relationship between at least one risk factor and delirium in the ED setting. Two investigators will use eligibility criteria from this protocol to independently screen titles and abstracts, and select studies based on full-text review of potentially eligible studies. After arriving at a final set of included studies, two investigators will extract data using a standardised data collection form. If appropriate, data regarding each risk factor will be pooled through a random-effect meta-analysis. The Grading of Recommendations Assessment, Development and Evaluation approach will be used to evaluate the overall quality of evidence.Ethics and disseminationTo our knowledge, this will be the first systematic review evaluating risk factors for prevalent and incident delirium specifically related to the ED setting. Results of this study will aid in the identification of older adults at risk for delirium in the ED. We aim to publish the results of this systematic review in a peer-reviewed journal with good visibility for the fields of emergency medicine and geriatrics.PROSPERO registration numberCDR42020175261

Published: July 2020

BackgroundWide-necked bifurcation aneurysms (WNBAs) present unique challenges for endovascular treatment. The Woven EndoBridge (WEB) device is an intrasaccular braided device, recently approved by the FDA for treatment of WNBAs. While treatment of intracranial aneurysms with the WEB device has been shown to yield an adequate occlusion rate of 85% at 1 year, few data have been published for patients with ruptured aneurysms.ObjectiveTo present a multi-institutional series depicting the safety and efficacy of using the WEB device as the primary treatment modality in ruptured intracranial aneurysms.MethodsA multi-institutional retrospective analysis was conducted, assessing patients presenting with aneurysmal subarachnoid hemorrhage treated with the WEB between January 2014 and April 2020. Baseline demographics, aneurysm characteristics, adverse events, and long-term outcomes (occlusion, re-treatment, functional status) were collected. A descriptive analysis was performed, and variables potentially associated with aneurysm recurrence or re-treatment were assessed.ResultsForty-eight patients were included. Anterior communicating artery aneurysms were the most common (35.4%) location for treatment, followed by middle cerebral artery (20.8%) and basilar apex (16.7%). Procedural success was noted in 95.8% of patients, and clinically significant periprocedural adverse events occurred in 12.5%. After a median follow-up of 5.5 months, 54.2% of patients had follow-up angiographic imaging. Complete occlusion was seen in 61.5% of cases with adequate occlusion in 92.3%. Re-treatment was required in only 4.2% of patients during the study period. Tobacco use was significantly higher in patients with aneurysm recurrence (88.9% vs 35.7%; p=0.012). No other characteristics were associated with recurrence/re-treatment. At 30 days, 81.1% were functionally independent (modified Rankin Scale score ≤2).ConclusionTreatment of acutely ruptured aneurysms with the WEB device demonstrates both safety and efficacy on par with rates of conventional treatment strategies.
Use of barley silage or corn silage with dry-rolled barley, corn, or a blend of barley and corn on predicted nutrient total tract digestibility and growth performance of backgrounding steers

Published: July 2020

The objective of this study was to determine the effects of feeding barley silage (BS) or corn silage (CS) with dry-rolled barley (BG), dry-rolled corn (CG), or a blend of barley and corn grain (BCG), on growth performance and nutrient digestibility, the latter predicted using near-infrared spectroscopy for backgrounding cattle. Steers (n = 288) were stratified by body weight (BW) into 24 pens and pens were randomly assigned to one of six treatments (n = 4) in a 2 × 3 factorial design. Main factors included BS or CS in combination with BG, CG, or BCG. There were no silage × grain interactions. Dry matter intake (DMI; P = 0.018) and final BW (P = 0.004) were greater for steers fed CS than BS, but average daily gain (1.01 kg d−1) and gain-to-feed ratio (0.10 kg kg−1) were not affected by silage or grain source. Steers fed CS also had greater dry matter, organic matter, crude protein (CP), acid detergent fiber (ADF), starch, and gross energy digestibility values (P < 0.01) than BS. Feeding BG increased starch, neutral detergent fiber, ADF, and CP digestibility values (P ≤ 0.01) over CG and BCG. Relative to BS, feeding CS increased DMI, final BW, and nutrient digestibility, whereas dry-rolled BG improved nutrient digestibility when compared with CG and BCG in backgrounding diets.
Comparative Acoustic Analyses of L2 English: The Search for Systematic Variation
Authors: Laturnus Rebecca 
Published: July 2020

Abstract

Background/Aims:
Previous research has shown that exposure to multiple foreign accents facilitates adaptation to an untrained novel accent. One explanation is that L2 speech varies systematically such that there are commonalities in the productions of nonnative speakers, regardless of their language background.
Methods:
A systematic acoustic comparison was conducted between 3 native English speakers and 6 nonnative accents. Voice onset time, unstressed vowel duration, and formant values of stressed and unstressed vowels were analyzed, comparing each nonnative accent to the native English talkers. A subsequent perception experiment tests what effect training on regionally accented voices has on the participant’s comprehension of nonnative accented speech to investigate the importance of within-speaker variation on attunement and generalization.
Results:
Data for each measure show substantial variability across speakers, reflecting phonetic transfer from individual L1s, as well as substantial inconsistency and variability in pronunciation, rather than commonalities in their productions. Training on native English varieties did not improve participants’ accuracy in understanding nonnative speech.
Conclusion:
These findings are more consistent with a hypothesis of accent attune­ment wherein listeners track general patterns of nonnative speech rather than relying on overlapping acoustic signals between speakers.
Transhumanism and Christianity
Authors: Lipowicz Markus 
Published: July 2020

Abstract
Although supporters of transhumanism present their agenda as a secular movement that specifically challenges the basic ontological and ethical premises of Christian metaphysics, there are also techno-progressive thinkers who claim that Christians should endorse a moderate version of biotechnological human enhancement. The main objective of this essay is to scrutinise this claim by outlining the relationship between transhumanism and Christian anthropology from the perspective of Joseph Ratzinger’s thought. The order of this analysis is constituted by three steps: first, I will critically analyse Benedikt Paul Göcke’s main arguments in favor of a Christian transhumanism; secondly, I will discuss the normative foundation of the techno-progressive agenda with regard to Ratzinger’s/Benedict XVI’s critique of the modern concept of freedom and its anthropological implication – the technological “new man”; finally, I will refer the notion of the posthuman to Ratzinger’s theo-evolutionary image of Jesus Christ as the “man of the future.”
