Politikerna struntar i klimatforskningen : 420 forskare: Regeringens politik är katastrofal – nu måste fler svenskar kräva en omställning

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.

Characterizing Ultrashort Laser Pulses With a Time-Dependent Polarization State Using the D-Scan Technique

The main idea behind the presented work is to extend the dispersion scan (d-scan) technique to measuring the time-dependent polarization state of ultrashort laser pulses. For demonstration, a rapidly varying polarization state, i.e. a polarization gate, was created from ultrashort pulses with a duration of 6 fs using a combination of wave plates. The time-dependent variation of the polarization wa

Persistent pain and its predictors after starting anti-tumour necrosis factor therapy in psoriatic arthritis : what is the role of inflammation control?

Objective: While considerable focus has been placed on pain due to inflammation in psoriatic arthritis (PsA), less is reported on pain despite inflammation control. Here, we aimed to investigate the occurrence/predictors of persistent pain, including non-inflammatory components, after starting anti-tumour necrosis factor (anti-TNF) therapy. Method: Bionaïve PsA patients starting a first anti-TNF t

On the influence of carbides in laser-cladded coating on friction, wear, and airborne particle emissions of disc brakes

Recently, it has become a focus to reduce non-exhaust aerosol emissions from the transport sector. One possible way to decrease brake particle emissions is by laser-cladding coatings onto brake discs. This work tested five different laser-cladding coated brake discs against a non-asbestos organic brake pad. The performance of these coatings was compared to a commercial grey cast iron brake disc te

Cationic Polymer Brushes Functionalized with Carbon Dots and Boronic Acids for Bacterial Detection and Inactivation

Drug-resistant bacterial infections are among the most severe physiological challenges facing human health. Therefore, the detection and inactivation of pathogenic bacteria remains a crucial therapeutic goal in modern society. In this study, we design multifunctional nanocomposites aimed at bacterial binding, fluorescence labeling, and synergistic antibacterial treatment. These nanocomposites are

Increased prevalence of osteopenia and osteoporosis in systemic sclerosis patients, including in men and young women—a case–control study

ObjectivesTo investigate bone mineral density (BMD), osteoporosis prevalence and SSc-specific associations of BMD in SSc patients compared with background population.MethodsIn total, 211 SSc patients (182 women, 29 men; mean age 61.3 and 62.2 years, respectively) and 505 age- and sex-matched controls from the same geographic area participated. BMD and T-score at total hip and lumbar spine was meas

Cyanobacterial Argonautes and Cas4 family nucleases cooperate to interfere with invading DNA

Prokaryotic Argonaute proteins (pAgos) from the long-A clade are stand-alone immune systems that use small interfering DNA (siDNA) guides to recognize and cleave invading plasmid and virus DNA. Certain long-A pAgos are co-encoded with accessory proteins with unknown functions. Here, we show that cyanobacterial long-A pAgos act in conjunction with Argonaute-associated Cas4 family enzyme 1 (ACE1). S

FLASH free electron laser pump-probe laser concept based on spectral broadening of high-power ytterbium picosecond systems in multi-pass cells

Within the FLASH2020+ upgrade, the pump-probe laser capabilities of the extreme ultraviolet and soft x-ray free-electron laser (XFEL) FLASH in Hamburg will be extended. In particular, providing wavelength tunability, shorter pulse durations, and reduced arrival time jitter will increase the scientific opportunities and the time resolution for the XFEL-optical laser pump-probe experiments. We prese

Energy scaling in a compact bulk multi-pass cell enabled by Laguerre-Gaussian single-vortex beams

We report pulse energy scaling enabled by the use of Laguerre-Gaussian single-vortex (LG0,l) beams for spectral broadening in a sub-40 cm long Herriott-type bulk multi-pass cell. Beams with orders l=1−3 are generated by a spatial light modulator, which facilitates rapid and precise reconfiguration of the experimental conditions. 180 fs pulses with 610 uJ pulse energy are post-compressed to 44 fs u

PIONEER big data platform for prostate cancer: lessons for advancing future real-world evidence research

Prostate Cancer Diagnosis and Treatment Enhancement through the Power of Big Data in Europe (PIONEER) is a European network of excellence for big data in prostate cancer. PIONEER brings together 34 private and public stakeholders from 9 countries in one multidisciplinary research consortium with the aim of positively transforming the field of prostate cancer clinical care by answering pressing que

Translation and Linguistic Validation of the Multidimensional Dyspnoea Profile into Telugu in a Palliative Care Setting

Objectives: Dyspnea, or breathlessness, is a frequent and distressing symptom among patients with heart and lung diseases, particularly in advanced cancer stages, where it affects up to 90% of lung cancer cases. This symptom considerably diminishes quality of life, leading to physical deconditioning, increased levels of anxiety and depression, repeated hospitalizations, and elevated mortality rate

Transport of Dipolar Excitons at the Type-II Polytype Interface of InP Platelets

The pursuit of high charge carrier mobility in nanostructures is crucial for advancing both device development and exploring fundamental physics. This study focuses on minimizing scattering to achieve high mobility, employing a polytype type-II interface formed between wurtzite and zincblende InP. On the zincblende side, electrons accumulate, while holes gather on the wurtzite side, resulting in t

Peripherally administered TNF inhibitor is not protective against α-synuclein-induced dopaminergic neuronal death in rats

The underlying cause of neuronal loss in Parkinson's disease (PD) remains unknown, but evidence implicates neuroinflammation in PD pathobiology. The pro-inflammatory cytokine soluble tumor necrosis factor (TNF) seems to play an important role and thus has been proposed as a therapeutic target for modulation of the neuroinflammatory processes in PD. In this regard, dominant-negative TNF (DN-TNF) ag

Temporal artery biopsy in giant cell arteritis : clinical perspectives and histological patterns

Although its role has been debated, temporal artery biopsy (TAB) remains the gold standard for the diagnosis of cranial giant cell arteritis (GCA). The specificity of TAB is excellent and the sensitivity, albeit lower, is comparable with other diagnostic modalities used for the diagnosis of GCA. This outpatient procedure has a low rate of complications and is well integrated in the majority of hea

Assessing housing accessibility issues for older adults in Japan : an expert panel approach to cross-cultural adaptation and content validity of the Japanese housing enabler

Accessible housing plays a crucial role in supporting aging in place, yet Japan lacks adequate tools for assessing housing accessibility among older adults. This study describes the process of translating and adapting the environmental component checklist of the Swedish Housing Enabler instrument for valid use in Japan. During translation to the Japanese language, technical terms and specification

Comparing phase sensitive detection and Fourier analysis of modulation excitation spectroscopy data exemplified by Ambient Pressure X-ray Photoelectron Spectroscopy

Dynamic processes in catalysis are gaining increased attention and could very well be one of the next frontiers in surface science. One way to study such processes is to induce chemical changes on the surface for example by periodically adjusting the (electro)chemical potential in situ and identify the resulting spectral changes. Often this is referred to as Modulation Excitation Spectroscopy (MES

Contributions of mean and shape of blood pressure distribution to worldwide trends and variations in raised blood pressure : A pooled analysis of 1018 population-based measurement studies with 88.6 million participants

Background: Change in the prevalence of raised blood pressure could be due to both shifts in the entire distribution of blood pressure (representing the combined effects of public health interventions and secular trends) and changes in its high-blood-pressure tail (representing successful clinical interventions to control blood pressure in the hypertensive population). Our aim was to quantify the

Local civil society regimes: liberal, corporatist and social democratic civil society regimes in Swedish metropolitan cities

Academic debates on the role and position of civil society organisations (CSOs) in welfare states largely refer to policies and practices outlined at the national level. They therefore fail to recognise variations within nations. Based on a comparative case study of three Swedish metropolitan cities, this article illustrates the importance of local, contextualised analyses.
