DEBATE. We researchers have long demanded that the government take climate research seriously and speed up the transition to a sustainable society.Instead, the government is pursuing a policy that deliberately increases emissions. Now more citizens need to raise their voices and show that we demand a knowledge-based climate transition, and it is urgent.
Fibril-reinforced poroviscoelastic material models are considered state-of-the-art in modeling articular cartilage biomechanics. Yet, cartilage material parameters are often based on bovine tissue properties in computational knee joint models, although bovine properties are distinctly different from those of humans. Thus, we aimed to investigate how cartilage mechanical responses are affected in t
Gas-phase transmission electron microscopy is an essential tool for elucidating the mechanisms involved in the synthesis of functional materials. Here, we review the latest developments in understanding the growth of novel nanostructural materials afforded by following the process in situ in electron microscopes. Particular focus is on investigations of catalyzed growth of one-dimensional carbon-b
In most non-fullerene organic solar cells comprising bulk-heterojunction active layers, the inter-domain connectivity of small-molecule acceptors is generally inferior to those of polymeric donors due to their intrinsic short-range ordering. This issue is even exacerbated by the physiochemical mismatch between acceptor-phases and metal-oxide electron transport layers in most inverted n-i-p devices
Neuromorphic computing has seen great interest as leaps in artificial intelligence (AI) applications have exposed limitations due to heavy memory access, with the von Neumann computing architecture. The parallel in-memory computing provided by neuromorphic computing has the potential to significantly improve latency and power consumption. Key to analog neuromorphic computing hardware are memristor
ABC-stacked multilayer graphene (ABC-MLG) exhibits topological surface flat bands with a divergent density of states, leading to many-body instabilities at charge neutrality. Here, we explore electronic ordering within a mean-field approach with full generic treatment of all spin-isotropic, two-site charge density and spin interactions up to next-nearest-neighbor (NNN) sites. We find that surface
Defects in metal halide perovskites (MHP) are photosensitive, making the observer effect unavoidable when laser spectroscopy methods are applied. Photoluminescence (PL) bleaching and enhancement under light soaking and recovery in dark are examples of the transient phenomena that are consequent to the creation and healing of defects. Depending on the initial sample composition, environment, and ot
AIM: To investigate the association between periodontitis and lung function in the Malmö Offspring Dental Study.MATERIALS AND METHODS: In all 1001 individuals (49.9% female, mean age: 44.6) from Malmö Offspring Dental Study were included. Periodontitis was assessed by a full-mouth examination protocol including bleeding on probing and classified according to the American Academy of Periodontology/
The development of highly specialized blood cells from hematopoietic stem cells (HSCs) in the bone marrow (BM) is dependent upon a stringently orchestrated network of stage- and lineage-restricted transcription factors (TFs). Thus, the same stem cell can give rise to various types of differentiated blood cells. One of the key regulators of B-lymphocyte development is early B-cell factor 1 (EBF1).
Haematopoietic stem cell (HSC) self-renewal is a process that is essential for the development and homeostasis of the blood system. Self-renewal expansion divisions, which create two daughter HSCs from a single parent HSC, can be harnessed to create large numbers of HSCs for a wide range of cell and gene therapies, but the same process is also a driver of the abnormal expansion of HSCs in diseases
Assessing short channel effects (SCEs) is crucial in the high-frequency optimization of downscaled field-effect transistors (FETs) such as GaN high electron mobility transistors (HEMTs). Drain-induced barrier lowering (DIBL) is commonly used for quantifying the ability of the gate to modulate the drain–source current at high drain voltages. DIBL is traditionally extracted from the relative shift o
The effects of substrate misorientation angle direction and degree on the structural properties of N-polar GaN grown by a novel multi-step temperature epitaxial approach using hot-wall metal–organic chemical vapor deposition (MOCVD) on 4H-SiC (0001̄) substrates is investigated. The surface morphology and X-ray diffraction (XRD) rocking curves (RCs) for both symmetric and asymmetric Bragg peaks of
Autism spectrum disorder (ASD) is a set of heterogeneous neurodevelopmental conditions, with a highly diverse genetic hereditary component, including altered neuronal circuits, that has an impact on communication skills and behaviours of the affected individuals. Beside the recognised role of neuronal alterations, perturbations of microglia and the associated neuroinflammatory processes have emerg
Suicide among children and young adults is a leading cause of mortality, highlighting the importance of the development of life-saving interventions. This study is part of the nationwide study Retrospective investigation of health care utilization of individuals who died by suicide in Sweden in 2015, Lund University, Sweden. The aim was to gain a better understanding of verbal suicidal communicati
This study investigates the interaction of KEIF, the intrinsically disordered N-terminal region of the magnesium transporter MgtA, with lipid bilayers mimicking cell membranes. Combining experimental techniques such as neutron reflectometry (NR), quartz-crystal microbalance with dissipation monitoring (QCM-D), synchrotron radiation circular dichroism (SRCD), and oriented circular dichroism (OCD),
Transfer RNA (tRNA)-derived RNAs (tDRs) are abundant small RNAs with emerging roles in development and tumorigenesis. Increasing evidence indicates that tDRs regulate stem cell homeostasis and differentiation, often altered in disease, highlighting the importance of fully characterizing their role in stem cell biology. Multiple studies point to protein synthesis as a crucial target of tDR-mediated
Time-resolved photoluminescence is a validated method for tracking the photoexcited carrier dynamics in luminescent materials. This technique probes the photoluminescence decays upon a periodic excitation by short laser pulses. Herein, we show that this approach cannot directly detect hidden photoexcitations with much slower dynamics than the photoluminescence decay. We demonstrate a new method ba
Background. Medulloblastoma (MB) is one of the most common malignant brain tumors in children. Current treatments have increased overall survival but can lead to devastating side effects and late complications in survivors, emphasizing the need for new, improved targeted therapies that specifically eliminate tumor cells while sparing the normally developing brain. Methods. Here, we used a sonic he
