It is essential that the design of atomizing sprays be tailored to the specific requirements of various industrial processes within, e.g., the agricultural or energy sector. However, the measurement of key atomizer parameters—central to the optimization of such systems—suffers from time-intensive techniques, complex calibration routines, and/or the need to include additives in the injected liquid.

Plasma-assisted technologies are rapidly advancing and are set to play a crucial role in the green transition. One challenge in this development, specifically tied to laser-based plasma diagnostics, is the presence of interfering plasma-induced emissions, such as the de-excitation of naturally excited species, which can complicate the detection of laser-induced signals. Successfully differentiatin

BACKGROUND: Atrial fibrillation (AF) often complicates ST-segment–elevation myocardial infarction (STEMI), but data on AF recurrence after first-ever AF during STEMI are scarce. We aimed at assessing the risk of AF recurrence after first-ever transient AF during admission for STEMI. METHODS: We performed a single-center, register-based cohort study. Patients with STEMI discharged alive after prima

Since the introduction of X-ray holotomography in projection geometry, this modality has proven to be highly effective for practical applications in the 100 nm spatial resolution range. However, one of the main obstacles to its implementation is the difficulty of producing a small focal spot, which determines the resolution of the projection microscope. To address this challenge, we present a simp

Sports-related concussions (SRCs) typically occur when the brain is hyperthermic. Acute head-and-neck cooling should, therefore, reduce the brain's metabolic demands, with the potential to improve recovery following an SRC. Elite ice hockey players who underwent head-and-neck cooling after sustaining a concussion (SRC) showed reduced return-to-play times, although further investigation is warrante

Consumption of ultra-processed food is associated with increased caloric intake and impaired health. Here, we conducted a nutrition trial (NCT05368194) with controlled, 2 × 2 crossover design and tested whether ultra-processed food impairs reproductive and metabolic fitness, with further aggravation by excess caloric intake. Comparing the response from an unprocessed to ultra-processed diet identi

Spray drying, a process which is widely used in the food industry, involves the atomizations of a liquid slurry into a drying chamber to produce a powder of desired properties. Although liquid viscosity strongly influences process efficiency, few studies have examined its effect on spray characteristics for specific system designs, where previous work has been hindered by experimental/numerical ch

Giving children with disabilities opportunities to explore how to use a powered mobility device is important for their development and learning. Encouraging and supporting exploration of how to set a device in motion and how to use it, has to be performed in harmony with each child and their abilities, needs and motivation. The experience of self-produced movement gives bodily feelings when action

Importance: Persistent disparities in mortality across countries suggest uneven improvements in living standards and access to life-extending health technologies, as well as context-specific obstacles. Studies have analyzed cross-country inequality in mortality but have not widely contextualized those disparities in terms of developmental progress relative to a frontier representing a level of mor

Ferroelectric thin films present a powerful platform for next-generation computing and memory applications. However, domain morphology and dynamics in buried ferroelectric stacks have remained underexplored, despite their importance for real device performance. Here, nanoprobe X-ray diffraction (nano-XRD) is used to image ferroelectric domains inside BiFeO3-based capacitors, revealing local disord

Certifying solvers have long been standard for decision problems in Boolean satisfiability (SAT), allowing for proof logging and checking with very limited overhead, but developing similar tools for combinatorial optimization has remained a challenge. A recent promising approach covering a wide range of solving paradigms is pseudo-Boolean proof logging, but this has mostly consisted of proof-of-co

In this issue of Cell Stem Cell, Márquez-Valadez, Gallardo-Caballero, and Llorens-Martín1 report that adult hippocampal neurogenesis (AHN) is differentially disrupted in neuropsychiatric disorders. Their findings highlight the role of the neurogenic niche and lifestyle, supporting the view of human AHN as a dynamic process sensitive to biology and behavior.

Transfecting clonal beta cells with large DNA plasmids holds significant promise for diabetes research. Existing transfection techniques like lipofection, viral transduction, and bulk electroporation often face limitations such as low efficiency and cytotoxicity. Nanoelectroporation, which utilizes nanopores or nanostraws and the application of mild electrical pulses, offers a gentle and safe alte

In the physical product development context, agile practices, particularly agile teams, are seldom applied as originally intended. They are often equated with traditional project teams, which conflicts with the fundamental principles of agile teams, undermining several associated benefits. Unlike traditional project teams, agile teams are ideally stable, focusing on continuously delivering value t

The thermal regime is a key indicator of permafrost evolution and thaw trajectories in response to climate change but remains poorly represented in global models. In this study, we applied the Moving-Grid Permafrost Model (MGPM), an efficient numerical model, to simulate the permafrost thermal regime in West Kunlun (WKL), a 55 669 km2 region on the remote northwestern Qinghai-Tibet Plateau charact

Rationally designing and fabricating high-performance core–shell nanostructures for catalytic organic synthesis is significant yet challenging. Here, we report a solvothermal/calcination strategy to prepare novel core–shell iron–aluminum oxide (FeAlOx) nanosphere-based nanoreactors incorporating active heterometals (AHM = Pd, Cu, or Mn). Leveraging the synergistic benefits of their unique core–she

The implementation of low-carbon futures requires both the assembling of new technologies, and practices, as well as the ‘unmaking’ of extant high-carbon infrastructures. Here, we bring together geographical, STS, anthropological, and sociological thinking on time to re-conceptualise such processes of unmaking. We argue that a focus on temporalities is especially pertinent to the unmaking of mater
