High frequency vertical InAs nanowire MOSFETs integrated on Si substrates

RF and DC characterization of vertical InAs nanowire MOSFET on Si substrates are presented. Nanowire arrays are epitaxially integrated on Si substrates by use of a thin InAs buffer layer. For device fabrication, high-k HfO2 gate dielectric and wrap-gates are used. Post-deposition annealing of the high-k is evaluated by comparing one annealed and one not-annealed sample. The annealed sample show be

Ophthalmologic Outcome of Extremely Preterm Infants at 6.5 Years of Age : Extremely Preterm Infants in Sweden Study (EXPRESS)

Importance: This follow-up study of extremely preterm (EPT) children (<27 weeks' gestational age [GA] at birth) revealed major eye and visual problems in 37.9% (147 of 388) of all EPT infants and in 55.4% (67 of 121) of the most immature subgroups at 6.5 years of age. These major eye and visual problems were strongly associated with treatment-requiring retinopathy of prematurity (ROP).Objectives:

Risk of second primary cancers after malignant mesothelioma and vice versa

We aimed at investigating risk of specific second primary cancers (SPCs) after malignant mesothelioma (MM) and vice versa, which has not been reported. Among survivors of 3672 pleural MM and 895 peritoneal MM, overall 113 and 28 SPCs were recorded, respectively, while reverse analyses included overall 431 pleural and 88 peritoneal MMs after any first cancers. We found a bidirectional association o

The rate of joint replacement in osteoarthritis depends on the patient's socioeconomic status : a cohort study of 71,380 patients

Background and purpose - Assessment of potential disparities in access to care is a vital part of achieving equity in health and healthcare. We have therefore studied the effect of socioeconomic status (SES) on the rates of knee and hip replacement due to osteoarthritis. Methods - This was a cohort study in Skåne, Sweden. We included all residents aged ≥ 35 years with consultations between 2004 an

Fighting infectious disease: Evidence from Sweden 1870-1940

Even more than in developing countries today, public health strategies to fight infectious disease in the past focused on the prevention of new infections by stopping their spread. These strategies were motivated by new insights into the causes of disease and the modes of transmission in the mid-nineteenth century. By combining longitudinal individual-level data on 17,000 children in a rural/semi-

Differences between occupations with respect to exit from working life

There is in large parts of the world a demographic crisis. Due to the increase in life length and the drop inbirth rates, prospects are that much fewer people of working age will be available in the future to supportthose in retirement.Also Sweden faces a demographic challenge, implying that it will be necessary to make the Swedeswork more years. There is an obvious potential in the age range 65-7

A 1-h Combination Algorithm Allows Fast Rule-Out and Rule-In of Major Adverse Cardiac Events

Background A 1-h algorithm based on high-sensitivity cardiac troponin T (hs-cTnT) testing at presentation and again 1 h thereafter has been shown to accurately rule out acute myocardial infarction. Objectives The goal of the study was to evaluate the diagnostic accuracy of the 1-h algorithm when supplemented with patient history and an electrocardiogram (ECG) (the extended algorithm) for predicti

Gestational hypertension, preeclampsia, and gestational diabetes mellitus after high exposure to perfluoroalkyl substances from drinking water in Ronneby, Sweden

Background: Leakage of fire-fighting foam from an airfield caused contamination of the drinking water supplied to a third of the population in Ronneby, resulting in very high serum levels of predominantly perfluorooctane sulfonate (PFOS) and perfluorohexane sulfonate (PFHxS). The results of studies investigating the association between exposure to perfluorinated alkyl substances (PFAS) and pregnan

Comparative effectiveness of Anti-IL5 and Anti-IgE biologic classes in patients with severe asthma eligible for both

Background: Patients with severe asthma may present with characteristics representing overlapping phenotypes, making them eligible for more than one class of biologic. Our aim was to describe the profile of adult patients with severe asthma eligible for both anti-IgE and anti-IL5/5R and to compare the effectiveness of both classes of treatment in real life. Methods: This was a prospective cohort s

Excitonic Dynamics at the Type-II Polytype Interface of InP Platelets

Indirect excitons are the focus of intense research due to the opportunity of studying degenerate quantum gases and liquids in an excitonic system. To realize such systems, it is highly advantageous to have as little scattering as possible. A polytype type-II interface is formed between wurtzite and zincblende InP due to the band alignment. Electrons gather on the zincblende and holes on the wurtz

Childhood neighborhoods and cause-specific adult mortality in Sweden 1939–2015

The socioeconomic health gradient has widened in recent decades. We study how childhood socioeconomic neighborhood conditions influence gender- and cause-specific adult mortality. Using uniquely detailed geocoded longitudinal microdata for a Swedish town (1939–1967), with a follow-up in national registers (1968–2015), we apply Cox proportional hazards models and estimate individual neighborhoods a

The Role of Energy Offsets on Charge Photogeneration Dynamics in Y-Series Molecules-Based Polymer Solar Cells

Recent research has revealed that low-energy offset polymer solar cells (PSCs) are capable of a power conversion efficiency of over 19%. However, it is unclear how energy offsets and the charge photogeneration process are correlated. Herein, the effect of energy offsets on charge photogeneration dynamics for Y-series molecules (Y5, Y6, Y10, and BTP-4F-12)-based PSCs with the variations of the lowe

Ultrafast Infrared-to-Visible Photon Upconversion on Plasmon/TiO2 Solid Films

Optical upconversion via a multiphoton absorption process converts incoherent low-energy photons to shorter wavelengths. In this contribution, we report a solid-state thin film for infrared-to-visible upconversion composed of plasmonic/TiO2 interfaces. When excited at λ = 800 nm, three photons are absorbed, leading to the excitation of TiO2 trap states into an emissive state in the visible domain.

Prolonged opioid use after distal radius fracture

BACKGROUND: Prolonged opioid use (more than 90 days) after injury puts the patient at risk for adverse effects. We investigated the patterns of opioid prescription after distal radius fracture and the effect of pre- and post-fracture factors on the risk for prolonged use.METHODS: This register-based cohort study uses routinely collected health care data, including purchases of prescription opioids

A New Instrument for Assessing Work-Related Body Mechanics and Strain in the General Population

Clinical pain is often linked to poor body mechanics, with individuals sometimes presenting multiple painful disorders. Such disorders may be influenced by behaviors that affect the general resiliency and health of the musculoskeletal system. We aimed to develop a self-reported scale using the Malmö Diet and Cancer Study questions on work-related body mechanical exposures. An expert panel identifi
