A real-time optical imaging system has been developed and commissioned at the European Spallation Source (ESS) to monitor the high-power proton beam at the tuning beam dump, and provide machine protection. The system employs chromium-doped alumina (Chromox) luminescent screens imaged by radiation-shielded optics and a CMOS camera. Real-time FPGA-based processing extracts beam size and position, de
Risk-based inspection (RBI) planning is concerned with the optimal allocation of deterioration control which is based on the pre-posterior analysis using the Bayesian decision theory and the expected utility theory. It has been widely used to make inspection and repair strategy in the field of civil engineering and infrastructure systems. Nowadays, with the developments of sensing and inspection t
Smart cameras are increasingly used in surveillance solutions in public spaces. Contemporary computer vision applications can be used to recognize events that require intervention by emergency services. Smart cameras can be mounted in locations where citizens feel particularly unsafe, e.g., pathways and underpasses with a history of incidents. One promising approach for smart cameras is edge AI, i
On August 7, 2020, the number 2 figure in al-Qaeda, Abdullah Ahmad Abdullah (known as Abu Muhammad al-Masri), was gunned down in Tehran. Al-Masri’s very presence in Iran exhibited the close relationship Tehran has with the Sunni terrorist organization, and his slaying shows the weakness of Iranian counterintelligence. The regime’s frustration at this intelligence failure will likely be expressed t
Aim: To explore if electrographic status epilepticus (ESE) after cardiac arrest causes additional secondary brain injury reflected by serum levels of two novel biomarkers of brain injury: neurofilament light chain (NfL) originating from neurons and glial fibrillary acidic protein (GFAP) from glial cells. Methods: Simplified continuous EEG (cEEG) and serum levels of NfL and GFAP, sampled at 24, 48
The precise separation of nanoscale particles has proven challenging due to diffusion and the need to use nanoscale devices. We show the separation of particles in the 100 nm size range in Deterministic Lateral Displacement (DLD) devices with feature sizes in the 10 µm size range. We achieve this using Dielectrophoretic (DEP) forces, generated between the metal coated posts that act as active elec
High throughput in particle and molecular sorting schemes is an important performance indicator and can be realized through increased volumetric processing rates or increased concentrations. Here we investigate the effect of increased concentration of high-molecular weight DNA in micropillar arrays for deterministic lateral displacement (DLD). We find that the array imposes regular fluctuations in
Stretching DNA in nanochannels allows for direct, visual studies of genomic DNA at the single molecule level. In order to facilitate the study of the interaction of linear DNA with proteins in nanochannels, we have implemented a highly effective passivation scheme based on lipid bilayers. We show long-term passivation of nanochannel surfaces to several relevant reagents and demonstrate that the pe
We have built an array of vertical nanotubes connected by a subsurface nanofluidic channel. The nanotube system is to be used for cell injections. By culturing cells on top of the nanotubes the cells will be pierced and molecules can enter the cells via the subsurface channel. Several channels can be made on the same sample and different molecules can be injected into different subpopulations of c
Policies aimed at sustainable landscape management recognise the importance of multiple cultural viewpoints, but the notion of landscape itself is implicitly assumed to be homogeneous across speech communities. We tested this assumption by collecting data about the concept of “landscape” from speakers of seven languages of European origin. Speakers were asked to freely list exemplars to “landscape
This article explores four preselected permanent magnet synchronous machine (PMSM) topologies suitable for direct mounting on low pressure spool in a turbo fan engine. The challenge of contributing to More Electric Engine (MEE) development is that the electrical machine needs to operate over wide speed range, take advantage of available space that forces to use a high number of poles and last but
Infectious diseases are the primary cause of mortality worldwide. The dangers of infectious disease are compounded with antimicrobial resistance, which remains the greatest concern for human health. Although novel approaches are under investigation, the World Health Organization predicts that by 2050, septicaemia caused by antimicrobial resistant bacteria could result in 10 million deaths per year
Old age is associated with an enhanced susceptibility to stroke and poor recovery from brain injury, but the cellular processes underlying these phenomena are not well understood. Potential mechanism underlying functional recovery after brain ischemia in aged subjects include neuroinflammation, changes in brain plasticity-promoting factors, unregulated expression of neurotoxic factors, or differen
Purpose: The eyelid is commonly dissected and divided in the process of, for example, blepharotomy, entropion repair, or when preparing a full-thickness eyelid flap to reconstruct a tumor defect. No study has yet been conducted to examine how perfusion in an eyelid is affected by dissection, using modern imaging techniques. Methods: The eyelid was divided with a 10-mm vertical incision, 5 mm from
Sustainability science emerged as a new academic field to address complex sustainability challenges. To train sustainability experts, sustainability science programs and sustainability-focused courses are offered in higher education, especially at the graduate level. Given the diverse topics and the complex structures of sustainability challenges, what are the required knowledge and skills needed
Background:: Those who are seriously ill and facing death are often living with physical, emotional, social, and spiritual suffering. Teamwork is considered to be necessary to holistically meet the diverse needs of patients in palliative care. Reviews of studies regarding palliative care team outcomes have concluded that teams provide benefits, especially regarding pain and symptom management. Muc
Astrocytes form functionally and morphologically distinct populations of cells with brain-region-specific properties. Human pluripotent stem cells (hPSCs) offer possibilities to generate astroglia for studies investigating mechanisms governing the emergence of astrocytic diversity. We established a method to generate human astrocytes from hPSCs with forebrain patterning and final specification wit

Limited information is available on adverse peri-intubation events.Objective To evaluate the incidence and nature of adverse peri-intubation events and to assess current practice of intubation in critically ill patients.Design, Setting, and Participants The International
