There is a growing call for comparative analyses of forest governance to facilitate knowledge exchange for the sustainable management of Nordic forest systems, addressing the needs of societal stakeholders in enhancing both the quality and quantity of forest resources. This study traces the development of nation-wide policy instruments implemented in four Nordic countries; Finland, Sweden, Norway

The high-frequency capacitive and switching response of ferroelectric Hf0.5Zr0.5O2 (HZO) is investigated on scaled ferroelectric metal-oxide-semiconductor III-V capacitors. Spanning over six orders of magnitude, the measured frequency response allows for accurate modeling of the capacitance-frequency dispersion. The steady-state ferroelectric behavior is retained even in the mm-wave frequency rang

The integration of functional materials into electronic devices has become a key approach to extending Moore’s law by increasing the functional density of electronic circuits. Here, we present a device technology based on ultrascaled ferroelectric, antiambipolar transistors (ferro-AAT) with robust negative transconductance, enabling a wide range of reconfigurable functionalities with applications

Vapor–solid–solid (VSS) growth of III-V semiconductor nanowires (NWs) has long been considered an alternative for the vapor–liquid–solid (VLS) growth mode, with the potential to avoid the incorporation of deep-level impurities into semiconductors and to form compositionally abrupt interfaces. Most research however indicates that VSS growth has a much lower growth rate than observed in the VLS grow

Heart failure is a leading cause of morbidity and mortality1,2. Elevated intracardiac pressures and myocyte stretch in heart failure trigger the release of counter-regulatory natriuretic peptides, which act through their receptor (NPR1) to affect vasodilation, diuresis and natriuresis, lowering venous pressures and relieving venous congestion3–8. Recombinant natriuretic peptide infusions were deve

The nonvolatile cryogenic memories can play an important role in realizing energy-efficient and scalable low-temperature electronics for quantum computing and future high-performance computing systems. In this article, we evaluate he cryogenic performance of HfOx-based resistive random access memory (RRAM) and demonstrate that the addition of extremely thin ∼0.5-nm AlOx barrier layers enables a h

Metal-halide perovskites (MHPs) have gained substantial interest in the energy and optoelectronics field. MHPs in nanostructure forms, such as nanocrystals and nanowires (NWs), have further expanded the horizons for perovskite nanodevices in geometry and properties. A partial anion exchange within the nanostructure, creating axial heterojunctions, has significantly augmented the potential applicat

Tunnel field-effect transistors (TFETs) are a potential alternative to MOSFETs for low-temperature electronics. We provide an in-depth experimental characterization of TFETs analyzing the fundamental physical behavior at different temperature regimes. TFET characteristics from 13 to 300 K both in forward and reverse bias are discussed by employing a variation in InAs/InGaAsSb/GaSb heterojunction v

A high turnover among principals may disrupt the continuity of leadership and negativelyaffect teachers and, by extension, the students. The aim was to investigate to what extent variouswork environment factors and signs of exhaustion were associated with reported intentions tochange workplace among principals working in compulsory schools. A web-based questionnaire wasadministered twice, in 2018

Reactive oxygen species (ROS) are considered to be an indicator of particle-induced toxicity. We used a novel instrument, called Particle Into Nitroxide Quencher (PINQ), for real-time quantification of ROS for assessment of indoor particle sources. Of the sources tested, cigarette smoke was found to contain the highest ROS concentration, several times higher than incense smoke and secondary organi

In this letter, we demonstrate low-frequency noise (LFN) characterization of an InAs vertical gate-all-around hafnium-zirconium oxide (HZO) ferroelectric field-effect transistor (FeFET). The LFN characteristics are investigated before and after ferroelectric switching for up to 1000 cycles in the FeFET. The evolution of such cycling reveals distinct differences in the LFN for the two polarization

The interaction of light with matter played a key role in the establishment of quantum mechanics, and each development of new light sources led to important advances in science, technology and society. An exciting area of physics has been opened with the new millennium, attosecond physics, where the motion of electrons can be studied at the fastest time scale ever reached with light. We review the

Purpose: Use of mechanical imaging (MI) as complementary to digital mammography (DM), or in simultaneous digital breast tomosynthesis (DBT) and MI - DBTMI, has demonstrated the potential to increase the specificity of breast cancer screening and reduce unnecessary biopsies compared with DM. The aim of this study is to investigate the increase in the radiation dose due to the presence of an MI sens

Steadily increasing use of computer-generated models sets high demands on the realistic representation of breast tissue and abnormalities. Previously, we demonstrated the use of Perlin noise to simulate breast lesions. Now, we expand the previous model by simulating heterogeneous lesion composition. We demonstrate a new approach to simulating 3D soft tissue lesions, with additional benefits of Per

Soil aggregate stability has been asserted as an indicator of soil quality. Earthworms are essential for the stability of soil aggregates due to their activities, including burrowing and organic matter decomposition. In this study, we focused on how differences in plant litter quality influences earthworm abundance and composition and, subsequently, macroaggregate stability in an agroforestry ecos
