MicroLED technology is expected to be the technology of choice for next-generation displays. Its advantages in various applications are reviewed. The challenges of microLED manufacturing, including red microLED realization, adequate efficiency, mass transfer, and structure and process design from a system perspective, are discussed with a special emphasis on how nano-scale material science may ope
The problem of finding maximum (or minimum) witnesses of the Boolean product of two Boolean matrices (MW for short) has a number of important applications, in particular the all-pairs lowest common ancestor (LCA) problem in directed acyclic graphs (dags). The best known upper time-bound on the MW problem for n× n Boolean matrices of the form O(n2.575) has not been substantially improved since 2006
This article highlights the role of external audiences and their perceptions in analysing the politicization of EU development policy. We analyse how EU foreign assistance is understood in two different intermediary arenas of politicization – elites in different societal sectors and media – within Ukraine, a major recipient of EU aid. By investigating to what extent EU assistance is perceived to b
Since 2014, Sweden has pursued the world's first Feminist Foreign Policy (FFP). However, the effectiveness of its policy promotion depends on how Sweden's efforts to spread this norm-based policy are perceived and evaluated by other states. We argue that a policy promotion effort has to be perceived as legitimate, coherent and salient by target populations in order to be effective. We investigate
Desire for life and protecting lives has come to the fore during the pandemic. Borders have been closed to stop the spread of Covid-19. The virus does not respect borders, yet physical distance is crucial. Three things have become clear. One is the level of uncertainty about which measures are most efficient. The other is that the neo-liberal philosophy with “just in time” deliveries on a global m
Biliary tract cancers (BTC) are rare and often diagnosed in late stages with advanced, nonresectable disease. The targeted agents panitumumab and bevacizumab have shown promising outcomes in combination with chemotherapy in other gastrointestinal (GI) cancers. We wanted to investigate if panitumumab or bevacizumab was the most promising drug to add to chemotherapy. Eighty-eight patients were rando
Chronic pancreatitis (CP) should be suspected in the case of recurrent upper abdominal pain of unknown origin and/or clinical signs of exocrine pancreatic insufficiency (EPI). Alcohol is the most common etiological factor associated with CP, others being smoking, male gender, and hereditary forms. CP is often associated with recurrent episodes of acute exacerbations. As of today, there is no accep
BACKGROUND: There is a lack of evidence-based recommendations for the age at which women with a family history of cancers other than breast cancer should start breast cancer screening. METHODS: Using Swedish family cancer data sets, the authors conducted a nationwide cohort study including 5,099,172 Swedish women born after 1931 (follow-up, 1958-2015). Accounting for calendar time, they calculated
Gut-associated lymphoid tissues (GALTs) comprise key intestinal immune inductive sites, including the Peyer’s patches of the small intestine and different types of isolated lymphoid follicle (ILF) found along the length of the gut. Our understanding of human GALT is limited due to a lack of protocols for their isolation. Here we describe a technique that, uniquely among intestinal cell isolation p
Objectives Despite the limited invasiveness of endoscopic transsphenoidal surgery (ETSS), some degree of nasal structure destruction is unavoidable. Our objective was to evaluate sinonasal morbidity and self-reported health before and 6 months after ETSS for pituitary tumors, and to identify possible predictive factors for deterioration in sinonasal health. Design Prospective observational cohort
Recent qualitative and quantitative research on the interrelationships between innovation, job quality and employment shows a strong association between job quality and product, process, and to a lesser extent organizational innovation. This is theorized as the interaction of two systems – job quality and innovation systems. Increased employment and improved job quality are found to result from inRecent qualitative and quantitative research on the interrelationships between innovation, job quality and employment shows a strong association between job quality and product, process, and to a lesser extent organizational innovation.

Context. Observations of the Galactic bulge suggest that the disk formed through secular evolution rather than gas dissipation and/or mergers, as previously believed. This would imply very similar chemistry in the disk and bulge. Some elements, such as the α-elements, are well studied in the bulge, but others like the neutron-capture elements are much less well explored. Stellar mass and metallici
Dermatan sulfate epimerase 1 (DS-epi1, EC 5.1.3.19) catalyzes the conversion of d-glucuronic acid to l-iduronic acid on the polymer level, a key step in the biosynthesis of the glycosaminoglycan dermatan sulfate. Here, we present the first crystal structure of the catalytic domains of DS-epi1, solved at 2.4 Å resolution, as well as a model of the full-length luminal protein obtained by a combinati
We report a new design of an acoustophoretic trapping device with significantly increased capacity and throughput, compared to current commercial acoustic trapping systems. Acoustic trapping enables nanoparticle and extracellular vesicle (EV) enrichment without ultracentrifugation. Current commercial acoustic trapping technology uses an acoustic single-node resonance and typically operates at flow
Self-Aware Adaptive computing systems are capable of adapting their behavior and resources thousands of times based on changing environmental conditions and demands. This allows them to automatically find the best way to accomplish a given goal with the resources at hand. This capability would benefit the full range of computer systems, from embedded devices to servers to supercomputers. Although
A feedback-based approach to process scheduling in a single-processor system was recently proposed, that deeply relies on the control theory for its entire design. In this work, a literature benchmark is used to compare said approach to classical ones, with particular reference to the real-time case. Two are the main results. First, in the case of a schedulable process set, the proposed "control-t
Recent papers [6, 8] have demonstrated that process schedulers can be designed entirely as feedback controllers - quite novel an approach with respect to the way the control theory is typically applied to computing systems. This work takes a more technological attitude with respect to the methodological ones just quoted. The realisation of a control-theoretical process scheduler on a kernel writte
