TL;DR: Masmoudi et al. as discussed by the authors proved the global existence of weak solutions for the co-rotational FENE dumbbell model and the Doi model also called the Rod model based on propagation of compactness.

TL;DR: The prevalence of IBS is strongly dependent on the classification algorithm employed, and the requirement of a minimum duration of symptoms eliminates IBS in a large number of subjects complaining of abdominal disorders.
Abstract: Summary Objectives The main objectives of this study were to assess whether the use of different definitions of irritable bowel syndrome (IBS) could influence measurements of its prevalence and characterize the patient population fulfilling these different diagnostic criteria. Method A telephone survey was carried out by contacting 8,221 subjects aged ≥ 18 years representative of the French population. A “screening” questionnaire based on three algorithms of IBS classification (Manning, with or without a notion of a minimal duration of symptoms, Rome I and Rome II) was used by specialised inquirers. Results Twenty three percent of the subjects interviewed stated that they had suffered from abdominal pain during the previous 12 months. The prevalence of IBS considerably varied, depending on the diagnostic criteria used: 12% based on Manning criteria without reference to the duration of symptoms; 2.5% if the notion of duration of symptoms was added to the Manning criteria, and 2.1% and 1.1% based on the Rome I and Rome II criteria, respectively (the latter including the same notion of duration). In total, 212 subjects (2.6%) met at least one of the criteria including a minimal duration of symptoms, with a predominance for women (sex-ratio close to 2). Conclusion The prevalence of IBS is strongly dependent on the classification algorithm employed. The requirement of a minimum duration of symptoms eliminates IBS in a large number of subjects complaining of abdominal disorders. Once these methodological variations were taken into account, the prevalence of IBS in France was found to be comparable to that published in international literature.

TL;DR: This work provides a framework to verify global optimality of a discrete transport plan locally and explicitly describes how to select the sparse sub-problems for several cost functions, including the noisy squared Euclidean distance.
Abstract: Discrete optimal transport solvers do not scale well on dense large problems since they do not explicitly exploit the geometric structure of the cost function. In analogy to continuous optimal transport, we provide a framework to verify global optimality of a discrete transport plan locally. This allows the construction of an algorithm to solve large dense problems by considering a sequence of sparse problems instead. The algorithm lends itself to being combined with a hierarchical multiscale scheme. Any existing discrete solver can be used as internal black-box. We explicitly describe how to select the sparse sub-problems for several cost functions, including the noisy squared Euclidean distance. Significant reductions in run-time and memory requirements have been observed.

TL;DR: It is suggested that disability and executive dysfunctions were independent predictors of perceived burden, whereas demographics, injury severity, and Glasgow Outcome Scale at discharge from acute care did not significantly correlate with caregiver's burden.
Abstract: OBJECTIVE:: To investigate predictors of informal care burden 1 year after a severe traumatic brain injury (TBI). PARTICIPANTS:: Patients (N = 66) aged 15 years or older with severe TBI (Glasgow Coma Scale score of 8 or less) and their primary informal caregivers. SETTING:: Multicenter inception cohort study over 22 months in Paris and the surrounding area (PariS-TBI study). MAIN MEASURES:: Patients' preinjury characteristics; injury severity data; outcome measures at discharge from intensive care and 1 year after the injury; Dysexecutive Questionnaire; Medical Outcome Study Short Form-36; Zarit Burden Inventory. RESULTS:: Among the 257 survivors at discharge from acute care, 66 patient-caregiver couples were included. Primary informal caregivers were predominantly women (73%), of middle age (age, 50 years), supporting male patients (79%), of mean age of 38 years. The majority (56%) of caregivers experienced significant burden, and 44% were at risk of depression. Caregivers' impaired health status and perceived burden significantly correlated with patients' global disability (as assessed with the Glasgow Outcome Scale-Extended) and impairments of executive functions (as assessed with the Dysexecutive Questionnaire). A focused principal component analysis suggested that disability and executive dysfunctions were independent predictors of perceived burden, whereas demographics, injury severity, and Glasgow Outcome Scale at discharge from acute care did not significantly correlate with caregiver's burden. CONCLUSION:: Global handicap and impairments of executive functions are independent significant predictors of caregiver burden 1 year after TBI. Language: en

TL;DR: In this article, a generalised maximum principle of Alexandrov-Bakelman-Pucci type for viscosity solutions of fully nonlinear cooperative elliptic systems was obtained.
Abstract: In this paper we obtain a generalised maximum principle of Alexandrov–Bakelman–Pucci type for viscosity solutions of fully nonlinear cooperative elliptic systems. We also establish a Harnack estimate for such systems and give some applications. In particular, a Harnack type estimate for solutions of higher order equations is given.
