AbstractGround penetrating radar is one of the promising non-destructive investigation for shallow subsurface exploration in locating buried utilities. However, interpreting hyperbolic signature of buried objects in GPR images remains a challenging task since the GPR signals are easily corrupted by environmental noise and cause misinterpretation of the size and geometry of subsurface object from the GPR raw profile. Therefore, this paper proposes Discrete Wavelet Transform (DWT) and principal component analysis (PCA) to classify geometry of buried object using k-nearest neighbour. (k-NN). The GPR images firstly being pre-processed. Then, the GPR images are decomposed using DWT into four sub-bands which are LL (Low-Low), LH (Low-High), HL (High-Low) and HH (High-High). The sub-bands LL or a coarse approximation coefficients was extracted as DWT features in order to classify the shape of buried objects. Since DWT features do contain high dimensional data, thus PCA is used to reduce the dimensional features from higher to lower space by linear transformation. The new projected features were then classify using k-NN classifier into four shapes which is cubic, cylinder, disc and sphere. A series of experiments have been conducted on extracted DWT and PCA features from hyperbolic signature of buried objects having different shapes. Based on the results, the proposed method had achieved the average recognition rate of 99.41%.

Abstract
Outdoor localisation can offer great capabilities in security and perimeter surveillance applications. The localisation of people become more challenges when involving with the nonlinear environment. GPS and CCTV are two localisation techniques usually use to localise human in an outdoor environment. However, they have weaknesses which result in low localisation accuracy. Therefore, the application of Device-free localisation (DFL), together with the Internet of things (IoT) is more appropriate due to their capability to detect the human body in all environmental conditions, and there is no problem losing signals as faced by GPS. This system offers excellent potential in humans localisation because humans can be detected wirelessly without any tracking device attached. In developing the DFL system, the main concern is the localisation accuracy. Although the existing DFL system gives significant result to the localisation, the accuracy is still low due to the large variation in RSSI values. Hence, a Radio Tomographic Imaging-based ANN classification (RTI-ANN) approach is proposed to increase the localisation accuracy. This Artificial Neural Network (ANN) is designed to learn the Radio Tomography imaging (RTI) input for classification purpose. Even though the RTI gives a good result to the localisation, however, it suffers from smearing effect. To eliminates this smearing area and background noise, pre-processing of the RTI image is required. Thus, extracting the valuable information technique from the RTI image has been proposed. By extracting the valuable information data from the RTI image, about 61% to 66% of the smearing noise is removed depending on the size of the RTI image. Only data directly associated with human attenuation used for training and learning of ANN. The experimental results show ANN system can localise human in the right zone for a given dataset.

Authors: Umurani K. , Siregar R.A. 
Published: December 2019

Abstract
This paper presents the development of dynamometer to measure cutting force in turning operation in particular the tangential force (Ft). The dynamometer utilises a straight bar load cell that connected to holder tool to measure at least one axis of force. The designed dynamometer is capable of computing the forces acting on the workpiece in turning operation using any data acquisition system. Two materials of low elastic modulus, Polyoxymethylene (POM) and Polytetrafluoroethylene (PTFE), were employed as workpieces to test the performance of dynamometer. The performance of the dynamometer to measure one axis of cutting forces is considered satisfactory mainly because of the simplicity and low cost are the main requirements in design and construction.
Case study on the soil physical parameters disparity and NPK concentrations in regions found in and around Pachapalayam, Coimbatore, Tamil Nadu.

Abstract
Deficient soil fertility is a major constraint in crop productivity. Soil characteristics such as pH, bulk density, electrical conductivity, moisture content, etc. play a major role in the health and yield of crops. Major nutrients such as Nitrogen (N), Phosphorus (P) and Potassium (K), are essential for the growth and yield of the crops as well. On account of the importance of soil physical properties and NPK concentration on the soil dynamics and plant development respectively, the study area was spatial distributed and geo-statistically analyzed to produce contour maps that can be used by decision makers in farm management for increased crop productivity.
‘I Am Also Having Mother Once, and She Is Loving Me’: Reading Cary Joji Fukunaga’s Beasts of No Nation in a Post-Network Era
Authors: Snell Heather 
Published: December 2019

AbstractThis article examines Cary Joji Fukunaga’s film adaptation of Uzodinma Iweala’s Beasts of No Nation, with a special focus on the final scene, in which a counsellor is assigned to help the protagonist deal with the trauma of having been a child soldier. While the casting of a black African actor as the counsellor in Fukunaga’s film may appear to detract from the novel’s interrogation of the uneven power relations between Africa and America, an interpretation oscillating between novel and film reveals that there may be some benefits to erasing the white saviour figure from the scene. The erasure of a white American character not only redirects the focus to relations among Africans but also comments indirectly on the circulation of transnational films via streaming services such as Netflix. Reading in between adapted text and adaptation also yields some important insights about Beasts’ critical engagement with the politics of circulation, reception, and consumption of child-soldier narratives at a time when such narratives have become popular among transnational audiences.

AbstractPurposeTo evaluate residency applicant (RA) and residency program director (RPD) perceptions of Phase II of the Match process since its inception in 2016.MethodsAn online survey was issued to all Match-registered RAs and RPDs for the 2016, 2017, and 2018 Match periods. Study participant demographics, participant designation (RA or RPD), the year(s) and Phase(s) of the Match participated in were measured using categorical ranges, and overall perceptions of the Match process since Phase II of the Match was implemented were captured with 5-point Likert scales.ResultsA total of 2,599 individuals (RA and RPD) completed the survey for an overall survey response rate of 12.6%. The majority of RAs were female (73.2%), under the age of 30 (87.4%), Caucasian (67.4%), and recently graduated (90.9% graduated between 2016 and 2018). Most RAs participated in the 2018 Match period (61%), and overall 82% successfully matched to a residency position. RA perceptions relating to process cost-effectiveness and perceived fairness to all applicants differed significantly from RPD perceptions (2.23 versus 3.71 and 2.80 versus 3.67, respectively; p &lt; 0.001 for each). There were no differences between RA and RPD perceptions related to the submission/review process.ConclusionThe Phase II of the Match process has demonstrated improved organization and satisfaction from the RPD perspective compared to the previous process. RAs have identified several areas for improvement in the process. It is imperative that efforts are made to continue expanding program and position offerings as much as possible.

Published: December 2019

AbstractMost prevalent neurodegenerative disorders take decades to develop and their early detection is challenged by confounding non-pathological ageing processes. For all neurodegenerative conditions, we continue to lack longitudinal gene expression data covering their large temporal evolution, which hinders the understanding of the underlying dynamic molecular mechanisms. Here, we overcome this key limitation by introducing a novel gene expression contrastive trajectory inference (GE-cTI) method that reveals enriched temporal patterns in a diseased population. Evaluated on 1969 subjects in the spectrum of late-onset Alzheimer’s and Huntington’s diseases (from ROSMAP, HBTRC and ADNI datasets), this unsupervised machine learning algorithm strongly predicts neuropathological severity (e.g. Braak, amyloid and Vonsattel stages). Furthermore, when applied to in vivo blood samples at baseline (ADNI), it significantly predicts clinical deterioration and conversion to advanced disease stages, supporting the identification of a minimally invasive (blood-based) tool for early clinical screening. This technique also allows the discovery of genes and molecular pathways, in both peripheral and brain tissues, that are highly predictive of disease evolution. Eighty-five to ninety per cent of the most predictive molecular pathways identified in the brain are also top predictors in the blood. These pathways support the importance of studying the peripheral-brain axis, providing further evidence for a key role of vascular structure/functioning and immune system response. The GE-cTI is a promising tool for revealing complex neuropathological mechanisms, with direct implications for implementing personalized dynamic treatments in neurology.

Abstract
Pattern similarity analyses are increasingly used to characterize coding properties of brain regions, but relatively few have focused on cognitive control processes in FrontoParietal regions. Here, we use the Human Connectome Project (HCP) N-back task functional magnetic resonance imaging (fMRI) dataset to examine individual differences and genetic influences on the coding of working memory load (0-back, 2-back) and perceptual category (Face, Place). Participants were grouped into 105 monozygotic twin, 78 dizygotic twin, 99 nontwin sibling, and 100 unrelated pairs. Activation pattern similarity was used to test the hypothesis that FrontoParietal regions would have higher similarity for same load conditions, while Visual regions would have higher similarity in same perceptual category conditions. Results confirmed this highly robust regional double dissociation in neural coding, which also predicted individual differences in behavioral performance. In pair-based analyses, anatomically selective genetic relatedness effects were observed: relatedness predicted greater activation pattern similarity in FrontoParietal only for load coding and in Visual only for perceptual coding. Further, in related pairs, the similarity of load coding in FrontoParietal regions was uniquely associated with behavioral performance. Together, these results highlight the power of task fMRI pattern similarity analyses for detecting key coding and heritability features of brain regions.
Temporal Dynam ics of the Neuregulin–ErbB Network in the Murine Prefrontal Cortex across the Lifespan
Authors: Paterson Clare , Cumming Brooke , Law Amanda J 
Published: December 2019

AbstractNeuregulin–ErbB signaling is essential for numerous functions in the developing, adult, and aging brain, particularly in the prefrontal cortex (PFC). Mouse models with disrupted Nrg and/or ErbB genes are relevant to psychiatric, developmental, and age-related disorders, displaying a range of abnormalities stemming from cortical circuitry impairment. Many of these models display nonoverlapping phenotypes dependent upon the gene target and timing of perturbation, suggesting that cortical expression of the Nrg–ErbB network undergoes temporal regulation across the lifespan. Here, we report a comprehensive temporal expression mapping study of the Nrg–ErbB signaling network in the mouse PFC across postnatal development through aging. We find that Nrg and ErbB genes display distinct expression profiles; moreover, splice isoforms of these genes are differentially expressed across the murine lifespan. We additionally find a developmental switch in ErbB4 splice isoform expression potentially mediated through coregulation of the lncRNA Miat expression. Our results are the first to comprehensively and quantitatively map the expression patterns of the Nrg–ErbB network in the mouse PFC across the postnatal lifespan and may help disentangle the pathway’s involvement in normal cortical sequences of events across the lifespan, as well as shedding light on the pathophysiological mechanisms of abnormal Nrg–ErbB signaling in neurological disease.
The endemic and endangered Maugean Skate (Zearaja maugeana) exhibits short-term severe hypoxia tolerance

Published: December 2019

AbstractThe endangered and range-restricted Maugean skate (Zearaja maugeana) is subjected to large environmental variability coupled with anthropogenic stressors in its endemic habitat, Macquarie Harbour, Tasmania. However, little is known about the basic biology/physiology of this skate, or how it may respond to future environmental challenges predicted from climate change and/or increases in human activities such as aquaculture. These skate live at a preferred depth of 5–15 m where the dissolved oxygen (DO) levels are moderate (~55% air saturation), but can be found in areas of the Harbour where DO can range from 100% saturation to anoxia. Given that the water at their preferred depth is already hypoxic, we sought to investigate their response to further decreases in DO that may arise from potential increases in anthropogenic stress. We measured oxygen consumption, haematological parameters, tissue–enzyme capacity and heat shock protein (HSP) levels in skate exposed to 55% dissolved O2 saturation (control) and 20% dissolved O2 saturation (hypoxic) for 48 h. We conclude that the Maugean skate appears to be an oxyconformer, with a decrease in the rate of O2 consumption with increasing hypoxia. Increases in blood glucose and lactate at 20% O2 suggest that skate are relying more on anaerobic metabolism to tolerate periods of very low oxygen. Despite these metabolic shifts, there was no difference in HSP70 levels between groups, suggesting this short-term exposure did not elicit a cellular stress response. The metabolic state of the skate suggests that low oxygen stress for longer periods of time (i.e. &gt;48 h) may not be tolerable and could potentially result in loss of habitat or shifts in their preferred habitat. Given its endemic distribution and limited life-history information, it will be critical to understand its tolerance to environmental challenges to create robust conservation strategies.
A Meta-Theoretical Systematic Review of the Culture-Centered Approach to Health Communication: Toward a Refined, “Nested” Model
Authors: Sastry Shaunak , Stephenson Megan , Dillon Patrick , Carter Andrew 
Published: December 2019

Abstract
While the influence of the culture-centered approach (CCA; Dutta, 2008 ) on health communication scholarship is undeniable, there has been no evaluation of its application in the field. Guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for systematic reviews (Moher, Liberati, Tetzlaff & Altman, 2009), we analyzed a corpus of empirical, peer-reviewed literature (n = 47) that used the CCA. Our findings demonstrate that (a) the ontological axis of the CCA (culture, structure, and agency) was widely used as a heuristic for defining health problems; and (b) studies varied widely in their adoption of the CCA’s epistemological axis (that of dialogic co-construction with marginalized communities), either at the level of problem definition, problem interpretation, and/or community participation. Finally, while most studies reported self-reflexivity in design, we coded for methodological and philosophical reflexivity to assess fidelity to the CCA axiology. Based on the variations and consistencies in its use, we offer a refined, “nested” conceptualization of the CCA.
The Visual Citizen in a Digital News Landscape
Authors: Allan Stuart , Peters Chris 
Published: December 2019

AbstractThis article’s contribution to theory-building focuses on the everyday circumstances under which journalism encourages a civic gaze. Specifically, it elaborates our heuristic conception of the “visual citizen” to explore journalism’s mediation of a politics of seeing, paying particular attention to how and why renderings of in/visibility signify varied opportunities for civic engagement within digital news landscapes. In recognizing a distinction between direct and virtual witnessing, it establishes a conceptual basis for an inductive typology delineating interrelated, potential citizen-subject positions across a continuum. Four such positions are identified and appraised, namely the visual citizen as: (a) news observer and circulator, (b) accidental news image-maker and contributor, (c) purposeful news image-maker and activist, and (d) creative image-maker and news commentator. Evaluating these positions in relation to their significance for visual journalism, this article aims to advance efforts to rethink the inscription of imagery in news reportage and its import for public life.
Irritable bowel syndrome-like symptoms in treated microscopic colitis patients compared with controls: a cross-sectional study
Authors: Pagoldh Jenny , Lundgren David , Suhr Ole B , Karling Pontus 
Published: December 2019

Abstract

Background
The prevalence of irritable bowel syndrome (IBS)-like symptoms is high in untreated patients with microscopic colitis (MC), but there is uncertainty of the prevalence of IBS-like symptoms in treated patients. We assessed the degree of IBS-like symptoms in patients with MC in comparison to control subjects, and investigated the association between IBS-like symptoms and faecal calprotectin (FC) in MC patients.

Methods
Patients with an established MC diagnosis (n = 57) were compared to sex- and age-matched controls (n = 138) for scores in the GSRS-IBS (Gastrointestinal Symptom Rating Scale for Irritable Bowel Syndrome) and HADS (Hospital Anxiety Depression Scale). In MC patients, an FC level was simultaneously analysed.

Results
The median interval from MC diagnoses to the time the subjects participated in the study was 5.5 years (25th–75th percentiles; 4.5–9.5 years). The total GSRS-IBS score, subscores for abdominal pain, bloating, and diarrhoea were significantly higher in MC patients compared to controls (all P &lt; 0.001). There was a significant correlation between FC levels and reported bowel frequency (P = 0.023), but there was no correlation between FC levels and GSRS-IBS scores. Patients with MC had significantly higher scores on anxiety (HADS-A) (P &lt; 0.001) and used more selective serotonin-reuptake-inhibitor drugs (P = 0.016) than the control subjects. However, only the control subjects (not the patients with MC) showed significant correlations between GSRS-IBS scores and HADS scores.

Conclusions
Patients with MC reported more IBS-like symptoms and anxiety than control subjects but neither FC levels nor symptoms of affectivity were significantly correlated with IBS-like symptoms.
A qualitative narrative review of protocols for women’s health on short-term medical missions in Latin America and the Caribbean
Authors: Dainton Christopher , Chu Charlene H 
Published: December 2019

Abstract

Background
Women’s health conditions are commonly encountered on short-term medical missions (STMMs) in Latin America and the Caribbean. There have been no previous attempts to describe women’s health protocols used by volunteer clinicians. This qualitative study aimed to describe areas of agreement between unpublished women’s health protocols from different North American STMM organizations and assess their concordance with published WHO guidelines.

Methods
A systematic web search was used to identify North American STMM sending organizations. Clinical protocols were downloaded from their websites and organizations were contacted to request protocols that were not published online. The protocols obtained were summarized, analysed thematically and compared to existing WHO guidelines.

Results
Of 225 organizations contacted, 112 (49.8%) responded and 31 of these (27.7%) had clinical protocols, of which 20 were obtained and analysed. Nine (45%) discussed sexually transmitted infections, six (30%) discussed pelvic inflammatory disease, two (10%) discussed prenatal care and two (10%) discussed menstrual disorders. None were the product of systematic literature searches and most were not referenced.

Conclusions
To avoid ineffective treatment and related harms to women, volunteer clinicians would benefit from the adaptation and distribution of guidelines for STMMs that are based on existing WHO guidance and acceptable to clinicians, patients and organizations.
Mitochondrial division, fusion and degradation
Authors: Murata Daisuke , Arai Kenta , Iijima Miho , Sesaki Hiromi 
Published: December 2019

Abstract
The mitochondrion is an essential organelle for a wide range of cellular processes, including energy production, metabolism, signal transduction and cell death. To execute these functions, mitochondria regulate their size, number, morphology and distribution in cells via mitochondrial division and fusion. In addition, mitochondrial division and fusion control the autophagic degradation of dysfunctional mitochondria to maintain a healthy population. Defects in these dynamic membrane processes are linked to many human diseases that include metabolic syndrome, myopathy and neurodegenerative disorders. In the last several years, our fundamental understanding of mitochondrial fusion, division and degradation has been significantly advanced by high resolution structural analyses, protein-lipid biochemistry, super resolution microscopy and in vivo analyses using animal models. Here, we summarize and discuss this exciting recent progress in the mechanism and function of mitochondrial division and fusion.
