This article is a survey of Louis Nirenberg's contributions to linear partial differential equations, focusing on his groundbreaking work on pseudo-differential operators and solvability.

In this paper we propose a shared regression network to jointly estimate the pose of multiple objects, replacing multiple object-specific solutions. We demonstrate that this shared network can outperform other similar approaches that rely on multiple object-specific models by evaluating it on the TLESS dataset using the VSD (Visible Surface Discrepancy). Our approach offers a less complex solution

The functionalization of small-molecule hole-transport materials (HTMs) heavily relies on the rational design of molecular geometry, which can optimize both intrinsic HTM properties and interfacial properties for realizing high-performance and stable lead halide perovskite solar cells (LHPSCs). Herein, two fluorene-based donor–π linker–donor HTMs are seen, FL01 and FL02, whose side chains are tail

Ceramic technology makes an abrupt appearance in the New World Arctic at circa 2800 cal BP. While there is general consensus that the ultimate source of these Alaskan pottery traditions lay in continental NE Asia, the motivations for the adoption of pottery in Alaska have remained unclear. Through organic residue analysis we investigated the function of Norton pottery in Southwest Alaska, and the

Background: Several studies described the cross-sectional characteristics of systemic sclerosis patients and coexisting primary biliary cholangitis, but longitudinal prognostic data are lacking. Aims: To describe the systemic sclerosis–primary biliary cholangitis phenotype, including baseline characteristics and outcomes. Methods: We performed a multicentre the European Scleroderma Trials and Rese

Recent advances in therapeutics are now providing a wide range of options for adults and children living with hemophilia. Although therapeutic choices are also increasing for the youngest individuals with severe disease, challenges remain about early management decisions, as supporting data are currently limited. Parents and healthcare professionals are tasked with helping children achieve an incl

3D integration of III-V semiconductors with Si CMOS is highly attractive since it allows combining new functions such as photonic and analog devices with digital signal processing circuitry. Thus far, most 3D integration approaches have used epitaxial growth on Si, layer transfer by wafer bonding, or die-to-die packaging. Here we present low-temperature integration of InAs on W using Si3N4 templat

Background The health of people with functional variation in Sweden is worse than people without functional variation. A health-promoting resource in adults’ lives is meaningful employment, and for people with functional variation it means some form of daily activity. The project "Grow with horsepower" is a person-centered and nature-oriented daily activity for people with function variation, who

In winter, a challenge to the immune system could pose a major energetic trade-off for small endotherms, whereby increasing body temperature (Tb; i.e. eliciting fever) may be beneficial to fight off invading pathogens yet incur a cost for vital energy-saving mechanisms. Having previously shown that the availability and acquisition of energy, through manipulation of food predictability, influences

This review summarizes and exemplifies the current understanding of osteoarthritis in vitro models and describes their relevance for new insights in the future of osteoarthritis research. Our friend and highly appreciated colleague, Prof. Alan Grodzinsky has contributed greatly to the understanding of joint tissue biology and cartilage biomechanics. He frequently utilizes in vitro models and carti

This chapter explores moral and ethical discussions that emerged in Sweden when the number of artificial grass pitches rose substantially. Based on research in the Swedish top-tier football league, named Allsvenskan, I shall present conflicting discourses that appear whenever grass is considered. The grass discussions often take a wider, political turn and reflect attitudes towards developments in

This chapter presents information on hydrogen as an energy carrier, its properties, how to produce and store it, how to transport it, as well as its role in future energy systems. Opportunities and concerns about hydrogen are discussed. The basic principles and analysis of the key transport phenomena, bottlenecks, and applications of fuel cells are discussed. Most attention is paid to so-called PE

Background: Women are less likely to receive oral anticoagulation or ablation for treatment of atrial fibrillation (AF). Identification of sex differences in arrhythmia characteristics and symptoms may lead to a better understanding of potential reasons for these differences. Objectives: To determine sex differences in AF with respect to heart rate, duration, burden, and symptoms in patients under

What is a football stadium? A structure that is most of the time empty in everyday life, but bursts with energy on matchdays. Its construction and maintenance cost a fortune, it occupies a lot of precious urban space and most often seems to facilitate undesired behaviour, such as letting off flares and smoke bombs, throwing chairs or water bottles, abusing and disparaging adversaries in any imagin

This chapter focuses on the dominantly gendered house-help in India: the cooks, cleaners, and maids during the pandemic-triggered lockdowns in Delhi and its metropolitan areas. Even if we are scared to enter people's homes, we have to come out to work to sustain our lives. The case studies of these three women point to the precarity and 'unrepresentability' which turn the previously invisible figu

Several lines of research within developmental psychology, experimental semiotics and language origins studies have recently converged in their interest in pantomime as a system of bodily communication distinct from both language (spoken or signed) and nonlinguistic gesticulation. These approaches underscore the effectiveness of pantomime, which despite lack of semiotic conventions is capable of c
