Quantum dots (QDs) can serve as near perfect energy filters and are therefore of significant interest for the study of thermoelectric energy conversion close to thermodynamic efficiency limits. Indeed, recent experiments in [Nat. Nano. 13, 920 (2018)1748-338710.1038/s41565-018-0200-5] realized a QD heat engine with performance near these limits and in excellent agreement with theoretical predictio
We compare III-V nanowire (NW) metal-oxidesemiconductor field-effect transistors (MOSFETs) in a vertical gate-all-around (GAA) as well as a lateral trigate architecture with planar reference MOSFETs and reveal that the NW geometry does not deteriorate the low-frequency noise (LFN) performance. In fact, with gate oxides deposited at the same conditions, the NW structures show potential to achieve b
Using electrically connected metal-coated posts in a deterministic lateral displacement (DLD) device and applying electric fields, electrokinetics is used to tune separations, significantly decrease the critical size for separation, and increase the dynamic range with switching times on the order of seconds. The strength of DLD stems from its binary behavior. To first approximation, particles move
BACKGROUND: Depression and anxiety are associated with adverse outcomes in educational achievements and economic performances. Moreover, the prevalence of these disorders is unequally distributed among different population subgroups. Our objective is to investigate whether the economic consequences of depression and anxiety differ between population subgroups of different gender, socioeconomic sta
The effect of alcohol intake on varicose veins (VV) has not been determined by its consumption level. The aim of this study was to investigate the association between alcohol intake and VV in an elderly general population. Using a cross-sectional approach, the Shimane CoHRE Study data, comprising a total of 1060 participants, were analyzed. By multivariate regression analysis adjusted with basic c
With advancing age, changes in the arterial wall contribute to what has been called vascular aging, and in some prematurely affected subjects even early vascular aging (EVA).1–5 Several years ago,1 we listed various components of EVA, including arteriosclerosis, atherosclerosis, and excess vasoconstriction, with their clinical expression: arterial stiffening and increased central pulse pressure, c
Estimating familial cancer risks is clinically important in being able to discriminate between individuals in the population at differing risk for malignancy. To gain insight into the familial risk for the different hematological malignancies and their possible inter-relationship, we analyzed data on more than 16 million individuals from the Swedish Family-Cancer Database. After identifying 153 11
The hybrid graphene-quantum dot devices can potentially be used to tailor the electronic, optical, and chemical properties of graphene. Here, the low temperature electronic transport properties of bilayer graphene decorated with PbS colloid quantum dots (CQDs) have been investigated in the weak or strong magnetic fields. The presence of the CQDs introduces additional scattering potentials that alt
Background: Despite its well-established positive effects, exercise-based cardiac rehabilitation (exCR) is underused in patients following an acute myocardial infarction (AMI). The aim of the study was to identify factors associated with non-Attendance at exCR in patients post-AMI in a large Swedish cohort. Methods: A total of 31,297 patients who have suffered an AMI, mean age 62.4 ± 4 years, were
Dopant atoms can be incorporated into nanowires either via the vapor-liquid-solid mechanism through the catalyst droplet or by the vapor-solid growth on the sidewalls. Si is a typical n-type dopant for GaAs, but in nanowires it often suffers from a strongly amphoteric nature in the vapor-liquid-solid process. This issue can be avoided by using Te, which is a promising but less common alternative f
We study a scenario where a monitor is interested in the freshest possible update from a remote sensor. The monitor also seeks to minimize the number of updates that exceed a certain freshness threshold, beyond which, the information is deemed to be too old. Previous work has presented results for First Come First Served (FCFS) systems. However, it has been shown that Last Come First Served (LCFS)
Low-dimensional semiconductor materials structures, where nanowires are needle-like one-dimensional examples, have developed into one of the most intensely studied fields of science and technology. The subarea described in this review is compound semiconductor nanowires, with the materials covered limited to III-V materials (like GaAs, InAs, GaP, InP,...) and III-nitride materials (GaN, InGaN, AlG
Nanoparticle superlattices consisting of densely packed particles with periodic arrangements can exhibit interesting collective properties different from those of individual nanoparticles and thus have attracted great interest in research due to their potential applications in optoelectronic, plasmonic, and magnetic devices[1, 2]. Evaporation-induced self-assembly on solid substrates which employs
Background: Microseminoprotein-beta (MSP), a protein secreted by the prostate epithelium, may have a protective role in the development of prostate cancer. The only previous prospective study found a 2% reduced prostate cancer risk per unit increase in MSP. This work investigates the association of MSP with prostate cancer risk using observational and Mendelian randomization (MR) methods. Patients
Data on familial risks in penile and vulvar/vaginal cancers and in second primary cancers (SPCs) following these cancers are limited. We used the Swedish Family-Cancer Database from years 1958 through 2015 to identify 3641 penile and 8856 vulvar/vaginal cancers and to calculate relative risks (RRs) and 95% confidence intervals (CIs) for these cancers according to site-specific cancer in family mem
We propose a model for the axial growth rate of nanowires grown by means of the vapor-liquid-solid mechanism. Our model is based on deposition-desorption-incorporation kinetics in steady state, and using this model we discuss nanowire growth in two experimentally relevant limits: mass transport limited growth and incorporation limited growth. We discuss our modeling results in view of experimental
Background and purpose: Our purpose was to study the association between country of birth and incident epilepsy in second-generation immigrants in Sweden. Methods: The study population included all children (n = 4 023 149) aged up to 18 years in Sweden. Epilepsy was defined as at least one registered diagnosis of epilepsy in the National Patient Register. The incidence of epilepsy, using individua
