Three different semiconductor nanowires are combined into a single optoelectronic artificial neuron. Our device provides a path towards low power computations with significantly reduced circuit footprint, thus addressing critical limitations in neuromorphic photonics. The false-coloured scanning electron micrograph shown in Figure 1a depicts the fabricated nanowire neuron. Two pin-doped InP nanowi
Photonics-based approaches to neuromorphic hardware offer advantages in speed and connectivity but often suffer from large device footprints.[1] Here, we present an ultra-compact artificial neuron built from semiconductor nanowires. A scanning electron micrograph of the nanowire device is presented in Figure 1a. Inside the dashed box, we show the neuron built from three III-V nanowires - two InP p
SETTING: Addis Ababa Tuberculosis Demonstration and Training Center, Ethiopia. OBJECTIVES: To determine the pattern of drug resistance among re-treatment cases of pulmonary tuberculosis (TB), to determine the risk factors associated with multi-drug resistant (MDR) TB, and to propose re-treatment regimens based on the patterns of susceptibility to first-line and alternative drugs. DESIGN: One hundr
We outline a descriptive framework of how candidate alleles of the immune system associate with infectious diseases in natural populations of animals. Three kinds of alleles can be separated when both prevalence of infection and infection intensity are measured-qualitative disease resistance, quantitative disease resistance and susceptibility alleles. Our descriptive framework demonstrates why all
Objective acoustic parameters have been measured in 30 school classrooms. These parameters include usual descriptors of the acoustic quality from the listeners’ standpoint, such as reverberation time, speech transmission index, and background noise level, and two descriptors of the acoustic properties for a speaker: Voice support and room gain. This paper describes the measurement method for these
Proteins from halophilic microorganisms thriving at high salinity have an excess of charged carboxylate groups, and it is widely believed that this gives rise to an exceptionally strong hydration that stabilizes these proteins against unfolding and aggregation. Here, we examine this hypothesis by characterizing the hydration dynamics of a halophilic model protein with frequency- and temperature-de
Repeated immunization of mice with bacterial superantigens induces extensive deletion and anergy of reactive CD4 T cells. Here we report that the in vitro proliferation anergy of CD4 T cells from TCR transgenic mice immunized three times with staphylococcal enterotoxin B (SEB) (3x SEB) is partially due to an increased frequency of Foxp3(+) CD4 T cells. Importantly, reduced number of conventional C
Popular Abstract in Swedish Att bär är nyttigt är ett påstående som de flesta känner igen. På butikshyllorna trängs våra nordiska bär med exotiska ”superbär” som utlovar att göra oss friska. Men vilka hälsoeffekter kan egentligen uppnås genom att äta bär? Är vissa bär mer nyttiga än andra? Forskningsresultaten som presenteras i denna avhandling visar att lingon, svarta vinbär och blåbär kan motverThe increasing prevalence of obesity is a worldwide health problem closely linked to diet and lifestyle factors. Obesity is associated with increased risk of several metabolic disorders including insulin resistance, nonalcoholic fatty liver disease and type 2 diabetes. Hence, there is a great need to identify dietary strategies for the prevention of obesity and related diseases. This thesis invest
Eosinophilia is a characteristic feature of many inflammatory diseases including inflammatory bowel disease and asthma. It also occurs in a subtype of rheumatoid arthritis but the role of eosinophils has been unclear and animal models have been lacking. Here, we introduce a new mouse model to study the role of eosinophilia in arthritis. Intraperitoneal injection of type II collagen alone, without
Objective: To study the association between maternal drug use in early pregnancy and orofacial cleft in the infant. Design: Register analysis based on prospectively collected information. Patients: All delivered women in Sweden July 1, 1995, through December 31, 2001. Main outcome measure: Presence of orofacial cleft in infant. Results: Prospective information on maternal drug use during the first

Some key political challenges today, e.g. climate change, are future oriented. The intergenerational setting differs in some notable ways from the intragenerational one, creating obstacles to theorizing about intergenerational justice. One concern is that as the circumstances of justice do not pertain intergenerationally, intergenerational justice is not meaningful. In this paper, I scrutinize thi
Human a-lactalbumin made lethal to tumor cells (HAMLET) and its analogs are partially unfolded protein-oleic acid (OA) complexes that exhibit selective tumoricidal activity normally absent in the native protein itself. To understand the nature of the interaction between protein and OA moieties, charge-specific chemical modifications of lysine side chains involving citraconylation, acetylation, and
Recently, we constructed a focused antibody library tailored to interact with haptens. High functionality of this library was demonstrated, as specific binders could be retrieved to a range of different haptens. In the current study we have developed a mutagenesis and selection strategy in order to further fine-tune the hapten binding properties of these antibody fragments. Testosterone was chosen
A density functional theory of the spatial distribution and biaxial nematic order of polymers of arbitrary length and rigidity inside a spherical cavity is proposed. The local order of different chain segments is considered as an alignment to a spatially varying director field of cylindrical symmetry. The steric interactions are taken into account in the second virial approximation. Polymer densit
A structural characterization of mixed micelles formed in aqueous solution by the PEO-PPO-PEO triblock copolymer P123 and the nonionic surfactant C(12)EO(6) was carried out using various techniques, including ultralow shear viscosimetry, depolarized dynamic light scattering (VH-DLS), depolarized static light scattering (VH-SLS), and small-angle X-ray scattering (SAXS). The sphere-to-rod transition
