    Agent architecture for adaptive behaviours in autonomous driving

    Get PDF
    Evolution has endowed animals with outstanding adaptive behaviours which are grounded in the organization of their sensorimotor system. This paper uses inspiration from these principles of organization in the design of an artificial agent for autonomous driving. After distilling the relevant principles from biology, their functional role in the implementation of an artificial system are explained. The resulting Agent, developed in an EU H2020 Research and Innovation Action, is used to concretely demonstrate the emergence of adaptive behaviour with a significant level of autonomy. Guidelines to adapt the same principled organization of the sensorimotor system to other agents for driving are also obtained. The demonstration of the system abilities is given with example scenarios and open access simulation tools. Prospective developments concerning learning via mental imagery are finally discussed

    Allopurinol-induced DRESS Syndrome or Drug Rash with Eosinophilia and Systemic Symptom is a rare but potentially fatal drug reaction. Fever, rashes, swelling, and hematologic abnormalities, particularly short-term or long-term injury to one or more organs, have been reported by over 0.4 percent of patients following the course of medicine. Here, a 54-year-old female patient was admitted to the hospital with complaints of fever, purpuric rashes over the body with itching mainly in the oral cavity and lips, and the extent to the upper back and lower limbs for three days. She had known complaints of Type 2 Diabetes, Systemic hypertension, Coronary artery disease with recent NSTEMI, Dyslipidaemia, Psychosis (20y), and Chronic kidney disease. She had been taking Allopurinol for the past three months for hyperuricemia. Allopurinol treatment stopped while topical Steroid treatment started along with supportive therapy. After ten days, the rashes improved significantly, allowing her to leave the hospital

    First-order structural transition in the magnetically ordered phase of Fe1.13Te

    Specific heat, resistivity, magnetic susceptibility, linear thermal expansion (LTE), and high-resolution synchrotron X-ray powder diffraction investigations of single crystals Fe1+yTe (0.06 < y < 0.15) reveal a splitting of a single, first-order transition for y 0.12. Most strikingly, all measurements on identical samples Fe1.13Te consistently indicate that, upon cooling, the magnetic transition at T_N precedes the first-order structural transition at a lower temperature T_s. The structural transition in turn coincides with a change in the character of the magnetic structure. The LTE measurements along the crystallographic c-axis displays a small distortion close to T_N due to a lattice striction as a consequence of magnetic ordering, and a much larger change at T_s. The lattice symmetry changes, however, only below T_s as indicated by powder X-ray diffraction. This behavior is in stark contrast to the sequence in which the phase transitions occur in Fe pnictides.Comment: 6 page

    Diabetes mellitus (DM) may complicate tuberculosis (TB) treatment and control. The National Institute of Health Research and Development in collaboration with seven referral public hospitals in Java and Bali established a disease registry system for tuberculosis (TB) and diabetes mellitus (DM). Medical records containing data of ≥15 years old patients, diagnosed with TB (ICD-10 code A15-A19) in 2014, with or without DM (ICD-10 code E10-E14) were recorded into case report form (CRF). From January 1st 2014 to January 12th 2016, the registry recorded 1975 TB cases, 15% of cases were TB-DM. 73.6% TB-DM were ≥45 years old and 70,8% TB-non DM were &lt;45 years old. Previously treated TB cases were higher than naïve in TB-DM (OR 2.588; 95%CI 2.0-3.4). In TB-DM, predominant symptoms were cough &gt;2 weeks (76.4%), weight loss (72.6%), loss of appetite (65.9%), and night sweats (65.2%). In TB-non DM, predominant symptoms were weight loss (59.4%), loss of appetite (57.8%), cough &gt;2 weeks (57.6%), and fever (56.9%). Higher chest X-rays abnormality in TB-DM (OR 7.249; 95%CI 3.2-16.5) and higher positive AFB smears (OR 2.568; 95%CI 1.8-3.8). TB treatment failure (death, defaulted, failure, or transferred out) were three times higher in TB-DM (aOR 3.042; 95%CI 1.7-5.4). TB-DM Registry showed negative effects of DM on clinical condition and the treatment success of TB. Abstrak Diabetes melitus (DM) menyulitkan pengobatan dan kontrol tuberkulosis (TB). Badan Penelitian dan Pengembangan Kesehatan bersama tujuh rumah sakit (RS) umum kelas A dan B di Pulau Jawa dan Bali mengembangkan Sistem Registri Penyakit TB-DM.

    To determine whether alcohol-dependent patients in a hospital setting benefit from extended brief interventions (EBI) delivered by an Alcohol Specialist Nurse. Methods Alcohol-dependent patients recruited via screening at the emergency department (ED) (n = 267), whether or not admitted to hospital, were randomized to EBI (up to six counselling sessions offered) or control. At 6 months, 84.2% of patients were assessed by a researcher blinded to the intervention. The primary outcome was a fall in Severity of Alcohol Dependence Questionnaire. Results There was no difference between groups in the primary outcome [odds ratio (OR) 1.02; 95% confidence interval (CI): 0.38, 2.75, P = 0.97]. Secondary outcomes including alcohol consumption and readiness to change did not show a significant difference between groups. However, all secondary outcome measures improved, on average, in both arms. Conclusions Although EBI can be delivered in an ED or inpatient setting, it was not shown to be an advantage over screening and usual management (which included advice on alternative services), with patients in both groups showing an average improvement

Introduction A number of studies have reported an association between peripheral hearing impairment, central auditory processing and Alzheimer\u27s disease (AD) and its preclinical stages. Both peripheral hearing impairment and central auditory processing disorders are observed many years prior to the clinical manifestation of AD symptoms, hence, providing a long window of opportunity to investigate potential interventions against neurodegenerative processes. This paper outlines the protocol for a systematic review of studies examining the central auditory processing functions in AD and its preclinical stages, investigated through behavioural (clinical assessments that require active participation) central auditory processing tests. Methods and analysis We will use the keywords and Medical Subject Heading terms to search the following electronic databases: MEDLINE, PsychINFO, PubMed, Scopus, EMBASE and CINAHL Plus. Studies including assessments of central auditory function in adults diagnosed with dementia, AD and its preclinical stages that were published before 8 May 2019 will be reviewed. This review protocol will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols guidelines. Data analysis and search results will be reported in the full review. This manuscript has designed the protocols for a systematic review that will identify the behavioural clinical central auditory processing measures that are sensitive to the changes in auditory function in adults with AD and its preclinical stages. Such assessments may subsequently help to design studies to examine the potential impact of hearing and communication rehabilitation of individuals at risk of AD. Ethics and dissemination Ethical approval is not required as this manuscript only reports the protocols for conducting a systematic review as primary data will only be reviewed and not be collected. The results of this systematic review will be disseminated through publication and in scientific conferences. PROSPERO registration number CRD42017078272

    Development and Application of Ultra-Performance Liquid Chromatography-TOF MS for Precision Large Scale Urinary Metabolic Phenotyping

    To better understand the molecular mechanisms underpinning physiological variation in human populations, metabolic phenotyping approaches are increasingly being applied to studies involving hundreds and thousands of biofluid samples. Hyphenated ultra-performance liquid chromatography-mass spectrometry (UPLC-MS) has become a fundamental tool for this purpose. However, the seemingly inevitable need to analyze large studies in multiple analytical batches for UPLC-MS analysis poses a challenge to data quality which has been recognized in the field. Herein, we describe in detail a fit-for-purpose UPLC-MS platform, method set, and sample analysis workflow, capable of sustained analysis on an industrial scale and allowing batch-free operation for large studies. Using complementary reversed-phase chromatography (RPC) and hydrophilic interaction liquid chromatography (HILIC) together with high resolution orthogonal acceleration time-of-flight mass spectrometry (oaTOF-MS), exceptional measurement precision is exemplified with independent epidemiological sample sets of approximately 650 and 1000 participant samples. Evaluation of molecular reference targets in repeated injections of pooled quality control (QC) samples distributed throughout each experiment demonstrates a mean retention time relative standard deviation (RSD) of <0.3% across all assays in both studies and a mean peak area RSD of <15% in the raw data. To more globally assess the quality of the profiling data, untargeted feature extraction was performed followed by data filtration according to feature intensity response to QC sample dilution. Analysis of the remaining features within the repeated QC sample measurements demonstrated median peak area RSD values of <20% for the RPC assays and <25% for the HILIC assays. These values represent the quality of the raw data, as no normalization or feature-specific intensity correction was applied. While the data in each experiment was acquired in a single continuous batch, instances of minor time-dependent intensity drift were observed, highlighting the utility of data correction techniques despite reducing the dependency on them for generating high quality data. These results demonstrate that the platform and methodology presented herein is fit-for-use in large scale metabolic phenotyping studies, challenging the assertion that such screening is inherently limited by batch effects. Details of the pipeline used to generate high quality raw data and mitigate the need for batch correction are provided
