Numerous workflow systems span multiple scientific domains and environments, and for the Internet of Things (IoT), Node-RED offers an attractive Web based user interface to execute IoT service-based workflows. However, like most workflow systems, it coordinates the workflow centrally, and cannot run within more transient environments where nodes are mobile. To address this gap, we show how Node-RED workflows can be migrated into a decentralized execution environment for operation on mobile ad-hoc networks, and we demonstrate this by converting a Node-RED based traffic congestion detection workflow to operate in a decentralized environment. The approach uses a Vector Symbolic Architecture (VSA) to dynamically convert Node-Red applications into a compact semantic vector representation that encodes the service interfaces and the workflow in which they are embedded. By extending existing services interfaces, with a simple cognitive layer that can interpret and exchange the vectors, we show how the required services can be dynamically discovered and interconnected into the required workflow in a completely decentralized manner. The resulting system provides a convenient environment where the Node-RED front-end graphical composition tool can be used to orchestrate decentralized workflows. In this paper, we further extend this work by introducing a new dynamic VSA vector compression scheme that compresses vectors for on-the-wire communication, thereby reducing communication bandwidth while maintaining the semantic information content. This algorithm utilizes the holographic properties of the symbolic vectors to perform compression taking into consideration the number of combined vectors along with similarity bounds that determine conflict with other encoded vectors used in the same context. The resulting savings make this approach extremely efficient for discovery in service-based decentralized workflows.

Trio-based whole-exome sequence (WES) data have established confident genetic diagnoses in ∼40% of previously undiagnosed individuals recruited to the Deciphering Developmental Disorders (DDD) study. Here we aim to use the breadth of phenotypic information recorded in DDD to augment diagnosis and disease variant discovery in probands. Median Euclidean distances (mEuD) were employed as a simple measure of similarity of quantitative phenotypic data within sets of ≥10 individuals with plausibly causative de novo mutations (DNM) in 28 different developmental disorder genes. 13/28 (46.4%) showed significant similarity for growth or developmental milestone metrics, 10/28 (35.7%) showed similarity in HPO term usage, and 12/28 (43%) showed no phenotypic similarity. Pairwise comparisons of individuals with high-impact inherited variants to the 32 individuals with causative DNM in ANKRD11 using only growth z-scores highlighted 5 likely causative inherited variants and two unrecognized DNM resulting in an 18% diagnostic uplift for this gene. Using an independent approach, naive Bayes classification of growth and developmental data produced reasonably discriminative models for the 24 DNM genes with sufficiently complete data. An unsupervised naive Bayes classification of 6,993 probands with WES data and sufficient phenotypic information defined 23 in silico syndromes (ISSs) and was used to test a “phenotype first” approach to the discovery of causative genotypes using WES variants strictly filtered on allele frequency, mutation consequence, and evidence of constraint in humans. This highlighted heterozygous de novo nonsynonymous variants in SPTBN2 as causative in three DDD probands.

Time-critical analytics applications are increasingly making use of distributed service interfaces (e.g., micro-services) that support the rapid construction of new applications by dynamically linking the services into different workflow configurations. Traditional service-based applications, in fixed networks, are typically constructed and managed centrally and assume stable service endpoints and adequate network connectivity. Constructing and maintaining such applications in dynamic heterogeneous wireless networked environments, where limited bandwidth and transient connectivity are commonplace, presents significant challenges and makes centralized application construction and management impossible. In this paper we present an architecture which is capable of providing an adaptable and resilient method for on-demand decentralized construction and management of complex time-critical applications in such environments. The approach uses a Vector Symbolic Architecture (VSA) to compactly represent an application as a single semantic vector that encodes the service interfaces, workflow, and the time-critical constraints required. By extending existing services interfaces, with a simple cognitive layer that can interpret and exchange the vectors, we show how the required services can be dynamically discovered and interconnected in a completely decentralized manner. We demonstrate the viability of this approach by using a VSA to encode various time-critical data analytics workflows. We show that these vectors can be used to dynamically construct and run applications using services that are distributed across an emulated Mobile Ad-Hoc Wireless Network (MANET). Scalability is demonstrated via an empirical evaluation.

Depression and burnout are highly prevalent among residents, but little is known about modifiable personality variables, such as resilience and stress from uncertainty, that may predispose to these conditions. Residents are routinely faced with uncertainty when making medical decisions.To determine how stress from uncertainty is related to resilience among pediatric residents and whether these attributes are associated with depression and burnout.We surveyed 86 residents in pediatric residency programs from 4 urban freestanding children's hospitals in North America in 2015. Stress from uncertainty was measured with the use of the Physicians' Reaction to Uncertainty Scale, resilience with the use of the 14-item Resilience Scale, depression with the use of the Harvard National Depression Screening Scale; and burnout with the use of single-item measures of emotional exhaustion and depersonalization from the Maslach Burnout Inventory.Fifty out of 86 residents responded to the survey (58.1%). Higher levels of stress from uncertainty correlated with lower resilience (r = -0.60; P .001). Five residents (10%) met depression criteria and 15 residents (31%) met burnout criteria. Depressed residents had higher mean levels of stress due to uncertainty (51.6 ± 9.1 vs 38.7 ± 6.7; P .001) and lower mean levels of resilience (56.6 ± 10.7 vs 85.4 ± 8.0; P .001) compared with residents who were not depressed. Burned out residents also had higher mean levels of stress due to uncertainty (44.0 ± 8.5 vs 38.3 ± 7.1; P = .02) and lower mean levels of resilience (76.7 ± 14.8 vs 85.0 ± 9.77; P = .02) compared with residents who were not burned out.We found high levels of stress from uncertainty, and low levels of resilience were strongly correlated with depression and burnout. Efforts to enhance tolerance of uncertainty and resilience among residents may provide opportunities to mitigate resident depression and burnout.

Bow hunter's syndrome (BHS) is a rare cause of vertebrobasilar insufficiency that occurs when the vertebral artery (VA) is occluded on rotation of the head and neck. This dynamic occlusion of the VA can occur anywhere along its course after it arises from the subclavian artery. Although most cases are associated with compression by osteophytes, cervical spondylosis, or lateral disc herniation, BHS has a highly variable clinical course that depends on the patient's specific anatomy. Therefore, it may be important for clinicians to be aware of anatomical variants that predispose individuals to BHS. Here, we report on a patient with BHS who was found to have two uncommon anatomical anomalies: an atretic right VA and a left-sided arcuate foramen.

A testicular varicocele is an abnormal dilation of the pampiniform plexus of veins within the spermatic cord. Due to the asymmetrical drainage pattern of the right and left testicular veins, the vast majority of varicoceles are found on the left side. Isolated right testicular varicoceles occur rarely and should raise clinical suspicion for underlying intra-abdominal pathology. During the dissection of a 67-year-old male cadaver a unilateral varicocele was discovered in the right spermatic cord. Upon dissection of the abdomen, a tumor was found in the head and body of the pancreas. The section of the inferior vena cava where the right testicular vein inserted laid directly posterior to the tumor and was markedly dilated. We hypothesize that this pancreatic tumor impeded venous return into the inferior vena cava from the right testicular vein and not the left renal vein (where the left testicular vein drains) resulting in a unilateral right varicocele (URV). To our knowledge, the relationship between URV and pancreatic cancer has not been previously described in the literature. Our findings suggest URV could be a clinical warning sign of cancer of the head and/or body of the pancreas and may be a source of discomfort to address in patients with pancreatic cancer in order to improve quality of life.

Introduction Hearing loss is a permanent and debilitating side-effect of a range of interventions commonly used in the treatment of childhood cancers, primarily ototoxic medications such as cisplatin. The purpose of this study was to examine the impact of hearing loss, in a population already at risk of reduced quality of life due to the cancer and treatment-related factors. Methods This study used a questionnaire specifically designed to tap issues relevant to children with hearing loss, the Paediatric Audiology Quality of Life questionnaire (PAQL). Parents of 78 children treated for a wide range of solid tumours and leukaemias completed the PAQL, 41 of whom had sensorineural hearing loss as a result of the cancer treatment. Results Significant differences between those children with hearing loss and those whose hearing remained normal were found on all four scales of the questionnaire. Children affected by ototoxicity were rated as having poorer quality of life in terms of their ability to communicate with family and peers, their independence, interactions with peers and emotional well-being. Conclusion These results highlight the impact of acquired hearing loss and reinforce the importance of assessing quality of life with a measure capable of tapping the issues of consequence to the population under investigation. They also have implications for the clinical management of children during and following treatment for a wide range of cancers: medically, audiologically, psychologically and educationally.

BACKGROUND: Patients with acute decompensated heart failure with diuretic resistance (ADHF-DR) have a poor prognosis. The aim of this study was to assess in patients with ADHF-DR, whether haemodynamic changes during ultrafiltration (UF) are associated with changes in renal function (Δcreatinine) and whether Δcreatinine post UF is associated with mortality. METHODS: Seventeen patients with ADHF-DR underwent 20 treatments with UF. Serial bloods (4-6 hourly) from the onset of UF treatment were measured for renal function, electrolytes and central venous saturation (CVO2). Univariate and multivariate analysis were performed to assess the relationship between changes in markers of haemodynamics [heart rate (HR), systolic blood pressure (SBP), packed cell volume (PCV) and CVO2] and Δcreatinine. Patients were followed up and mortality recorded. Cox-regression survival analysis was performed to determine covariates associated with mortality. RESULTS: Renal function worsened after UF in 17 of the 20 UF treatments (baseline vs. post UF creatinine: 164±58 vs. 185±69μmol/l, P

Objectives Exposure to adversity has been linked to accelerated biological aging, which in turn has been shown to predict numerous physical and mental health problems. In recent years, measures of DNA methylation-based epigenetic age––known as “epigenetic clocks”––have been used to estimate accelerated epigenetic aging. Although a small number of studies have found an effect of adversity exposure on epigenetic age in children, none have investigated if there are “sensitive periods” when adversity is most impactful. Methods Using data from the Avon Longitudinal Study of Parents and Children (ALSPAC; n = 973), we tested the prospective association between repeated measures of childhood exposure to seven types of adversity on epigenetic age assessed at age 7.5 using the Horvath and Hannum epigenetic clocks. With a Least Angle Regression variable selection procedure, we evaluated potential sensitive period effects. Results We found that exposure to abuse, financial hardship, or neighborhood disadvantage during sensitive periods in early and middle childhood best explained variability in the deviation of Hannum-based epigenetic age from chronological age, even after considering the role of adversity accumulation and recency. Secondary sex-stratified analyses identified particularly strong sensitive period effects. These effects were undetected in analyses comparing children “exposed” versus “unexposed” to adversity. We did not identify any associations between adversity and epigenetic age using the Horvath epigenetic clock. Conclusions Our results suggest that adversity may alter methylation processes in ways that either directly or indirectly perturb normal cellular aging and that these effects may be heightened during specific life stages.

Weather and climate extremes have impacted forage conditions and lead to loss of animal production and livelihood of livestock-dependent communities in Kenya. Monitoring of forage conditions and developing a reliable early warning system can reduce the loss of livestock and improve the resilience. In order to enhance resilience of affected populations, through a collaboration of multiple agencies in Kenya and beyond, a dynamic web-based Predictive Livestock Early Warning System (PLEWS) decision support tool was developed. The system combines the water balance, PHYGROW (Phytomass Growth Model) simulation model and spatial analysis tools to generate current and a 6-monthly forecast of forage conditions. Although in its pilot phase, the tool holds potentials to provide decision support with anticipatory actions by communities, regional and national governments. By utilizing the output and engaging such pre-emptive interventions, emergencies can be prevented by promoting proactive decision-making conditioned on advance information of forage conditions. Timely actions based on advanced information can reduce potential impacts of extreme weather and climate events on livestock. The pro-active actions can reduce the losses and response costs associated with the impacts of weather, climate extremes and can improve food security of most vulnerable populations.

Background Exposure to “early life” adversity (e.g., in the first two decades of life) is known to predict DNA methylation (DNAm). However, few studies have investigated whether adversity has time-dependent effects based on the age at exposure. Methods Data for our prospective study came from the Accessible Resource for Integrated Epigenomics Studies (ARIES), a subsample of 1,018 mother-child pairs from the Avon Longitudinal Study of Parents and Children (ALSPAC). Results After covariate and cell-type adjustment and Bonferroni correction for multiple testing, we identified 40 CpG sites that were differentially methylated following exposure to adversity. Nearly all of these loci (n=38) were related to adversity exposure in infancy. Financial stress, maternal psychopathology, and neighborhood disadvantage predicted the greatest number of epigenome-wide DNAm changes. Discussion These results suggest that the developmental timing of adversity explains more variability in DNAm than the accumulation or recency of exposure. Infancy appears to be a sensitive period when exposure to adversity predicts differential DNAm patterns.

Objectives Hip arthroplasty registries, encompassing all-cause end-stage hip degeneration, have shown that slightly more right hip replacements are performed than left. Given that greater than 85% of individuals are right-handed, we sought to investigate the association between side of hand dominance and side of hip osteoarthritis. Methods This Level III observational study evaluated exclusively end-stage osteoarthritis of the hip, using 3 independent centres totalling 386 consecutive arthroplasty patients. Logistic regression was used as a statistical model. Results In total, 322 patients with hip osteoarthritis were included in the final analysis, including 146 (45.5%) women and 176 (54.5%) men, with a mean age of 68.1 years (SD = 9.5 years). There were 133 (41.2%) right, 73 (22.6%) left, and 116 (35.9%) bilateral hips where the contralateral side had been previously replaced. The proportion of individuals requiring unilateral hip arthroplasty on their dominant side was 67.4%. Conclusions In the development of hip osteoarthritis, one is significantly more likely to require hip arthroplasty on their dominant side than in the contralateral hip. Assessment of hand dominance identifies cerebral laterality as a contributing factor in predisposing one’s dominant side to hip osteoarthritis.

P -Splines are commonly used for derivative estimation where a non-linear relationship exists between the response and explanatory variables. However, questions about the error of these estimates have arisen. Incorporating an extra penalty term in a P -Spline model is proposed as an improvement when derivative estimation is of primary concern. This additive penalty approach to derivative estimation is shown to improve on the P -Spline estimates based on the results of a simulation study to compare the performance when estimating the first and second derivatives of six simulated functions. A method for generating variability bands for P -Spline derivative estimates with and without an additive penalty is given. The proposed additive penalty variability bands are shown to behave better than their single penalty counterpart. Motivating examples in environmental and sports science are used to demonstrate the need for accurate derivative estimates and the benefit of using an additional penalty term to this end.

Road transport is the second largest producer of greenhouse gases within the European Union. This project, Energy Efficient VEhicles for Road Transport (EE-VERT) targets a 10-12% reduction in fuel consumption and CO2 generation for conventional vehicles with only minimal changes. Hybrid Electric Vehicles (HEVs) and Full Electric Vehicles (EVs) offer good CO2 savings but their market penetration is slow, therefore conventional vehicles will play a significant role for the foreseeable future. Despite improvements in modern conventional vehicles, a considerable amount of energy is wasted due to the lack of an overall on-board energy management strategy. Electrification of auxiliary systems and operating them only when needed promises energy and efficiency gains, but there is an additional need for a coordinated approach to the generation, distribution and use of energy. EE-VERT offers a solution to bridge the gap in the market between present conventional vehicles and HEVs/EVs. The central EE-VERT concept is the electrification of auxiliary systems and supplying their energy from energy sources such as recuperated braking energy, waste heat recovery or solar cells, as part of an overall energy management strategy. The conventional car uses a 14V network and the EE-VERT concept retains the majority of this to minimise additional costs. However, to achieve improved efficiency and power, the generator operates at 40V. To connect the elements to the standard electrical system a new architecture has been devised that works with 40V and 14V levels. The main components of the 40V network are a new generator based on the claw pole technology with integrated permanent magnets, a Li-Ion battery system and a DC/DC converter with multiple inputs (MIPEC) for interfacing between the two voltage levels and the additional energy sources such as the solar panel. The available generator power during recuperation is up to 11kW. The efficiency of the new generator is above 80% in the low range of speed while in the high range of speed the efficiency is still above 70%. The MIPEC efficiency is around 94%. The simulation work indicates that average fuel savings of 10% for real life driving cycles and up to 17% when the start and stop functionality is applied to real life urban cycles are possible and that real life urban driving cycles benefit the most from the EE-VERT concept. The final phases of the project work on the Test Bench and with the demonstrator car will confirm the potential fuel saving benefits of the EE-VERT concept.
