We investigate self-heating in vertical, gate-all-around III-V InAs/InGaAs nanowire MOSFETs using pulsed IV measurements at various temperatures. Low temperature measurements reveal a negative output conductance indicating self-heating in the transistor. Under pulsed measurements, an increase in drain current (15%) and transconductance (30%) are observed at room temperature, with values influenced

In this article I investigate the spatial development of Swedish district courthouses and their different room types from 1970 to 2020, with attention to the specificities and commonalities with other building types. How have spatial form and use travelled between building types during this period, and how has this contributed to the recent, quite radical developments and transformation of the cou

A conceptual design of a year 2035 turbofan is developed and integrated onto a year 2035 aircraft model. The mission performance is evaluated for CO2, noise and NOx and is compared with a notional XWB/A350-model. An OGV heat exchanger is then studied rejecting heat from an electric generator, and its top-level performance is evaluated. The fan, the booster and the low-pressure turbine of the propu

Western missionaries became important eyewitnesses of the 1915 Armenian genocide, and many reported on the events. This article analyses witness reporting from a biographical and gendered perspective, taking into account the significance of studying local activism and transnational networks in a humanitarian setting. Taking the witness accounts of the Swedish missionary Alma Johansson as an exampl

Propolis is a resin-like material produced by bees from the buds of poplar and cone-bearing trees and is used in beehive construction. Propolis is a common additive in various biocosmetics and health-related products, despite the fact that it is a well-known cause of contact allergy. Caffeic acid and its esters have been the primary suspects behind the sensitization potency of propolis-induced con

A combustion Large Eddy Simulation (LES) is used to examine the flow, mixing, fuel-injection and combustion dynamics of a ramjet combustor with a cavity flame holder. The combustor is a running 50/50, in mole, ethylene/hydrogen fuel mixture. A direct-connect facility dual-mode ramjet/scramjet combustor presents the target case, with in the literature available experimental data is used in the pres

The semiconductor technology development con- stantly enables integrated circuits (ICs) with more, faster and smaller transistors. While there are many advantages, there are also many and new challenges, for example tighter margins, wear- outs and process variations. To address these challenges, the traditional approach with external test instruments used at man- ufacturing test must be complement

Aims: Pleural mesothelioma (PM) is a highly aggressive thoracic tumour with poor prognosis. Although reduced tissue drug accumulation is one of the key features of platinum (Pt) resistance, little is known about Pt distribution in human PM. Methods: We assessed Pt levels of blood samples and surgically resected specimens from 25 PM patients who had received neoadjuvant Pt-based chemotherapy (CHT).

Operando X-ray studies of chemical reactions have gained increasing interest lately, fueled by the emergence of a new generation of powerful focused X-ray sources. Although it is well known that ionizing radiation causes damage to samples via radical chemistry, this effect is often overlooked in studies of working devices or catalysts where intense focused beams are used as nanoscale probes. Here,

The work focuses on analysis and development of integrated low-pressure shaft generator in a geared twin-spool turbofan engine. It starts with manufacturing and evaluation of direct cooled hollow conductor coils, and has focus manufacturing, assembling and integration issues essential to machine design. The experiment-in-loop, but the model-based evaluation focuses not only on the coolant and cool

Electromagnetic induction (EMI) methods are often used to map rapidly large areas with minimal logistical efforts. However, they are limited by a small number of frequencies and by their severe ill-posedness. On the other hand, electrical resistivity tomography (ERT) results are generally considered more reliable, with no need for specific calibration procedures and easy 2D/3D inversion. Still, ER

Streamflow estimation is important in hydrology, especially in drought and flood-prone areas. Accurate estimation of streamflow values is crucial for the sustainable management of water resources, the development of early warning systems for disasters, and for various applications such as irrigation, hydropower production, dam sizing, and siltation management. This study developed the ANN algorith
