  2. 1. Correctness and Safety in Planning and Control via State-Space Partitions and Barrier Functions

    Author : Xiao Tan; Dimos V. Dimarogonas; Samuel Coogan; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamical systems; Control barrier functions; Optimeringslära och systemteori; Optimization and Systems Theory;

    Abstract : Autonomous systems have become increasingly prevalent in various industries, ranging from household cleaning robots to line inspection drones and copilot vehicles. Ensuring real-time safety is becoming a critical issue when the environment is rapidly changing. READ MORE

  4. 2. Effects of 5-fluorouracil on oral barrier functions

    Author : Inger von Bültzingslöwen; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Many anticancer drugs, e.g. 5-fluorouracil (5-FU), may cause oral mucositis and ulcerations. These adverse reactions can be severe and debilitating to the patient, and adjustment of the cancer treatment may be necessary. READ MORE

  5. 3. Functions of Pericytes in Ischemic Stroke

    Author : Michaela Roth; Lund Neurologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Stroke; Pericytes; RGS5; Blood-brain barrier; vascular remodelling; scar formation;

    Abstract : Ischemic stroke remains one of the leading causes of death and disability worldwide, and its burden is predicted to further increase due to the aging population. The only available treatments, thrombolysis or thrombectomy, can only be applied within a limited time window after stroke onset, and thus are applicable only to a small proportion of stroke patients.

  6. 4. Partitioning and Control for Dynamical Systems Evolving on Manifolds

    Author : Xiao Tan; Dimos V. Dimarogonas; James D. Biggs; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Partitioning and control; Transition system; Geometric control; Barrier functions; Electrical Engineering; Elektro- och systemteknik;

    Abstract : With the development and integration of cyber-physical and safety-critical systems, control systems are expected to achieve tasks that include logic rules, receptive decision-making, safety constraints, and so forth. For example, in a persistent surveillance application, an unmanned aerial vehicle might be required to "take photos of areas A and B infinitely often, always avoid unsafe region C, and return to the charging point when the battery level goes low.

  7. 5. Gut microbiota to counteract metabolic disorders and neuroinflammation : Impact of dietary factors and their potential to prevent Alzheimer’s disease

    Author : Nittaya Marungruang; Avdelningen för livsmedel och läkemedel; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer’s disease; gut microbiota; metabolic disorders; inflammation; neuroinflammation; lingonberries; dietary fibre; gut barrier; blood-brain barrier;

    Abstract : Alzheimer’s disease (AD) is the most common form of dementia. Increased accumulations of senile plaques and tangles are the known neuropathological hallmarks of AD. However, the exact triggers for such protein accumulations, leading to cognitive impairment and important morphological alteration in AD, are still elusive. READ MORE
