Commuting Challenges for Big Cities: How to Tackle Particulate Matter Human Exposure?

open access: yesCLEAN – Soil, Air, Water, Volume 54, Issue 4, April 2026.
ABSTRACT Air quality in large cities is a global public health issue that has received increasing attention in recent decades. The dynamics of atmospheric pollutant concentrations form a complex system influenced by meteorology, topography, emission sources, and fleet composition, interacting in a nonlinear pattern. We monitored particulate matter (PM)

A Systematic Review of Grid-Forming Control Techniques for Modern Power Systems and Microgrids

open access: yesEnergies
Looking toward the future, governments around the world have started to change their energy mix due to climate change. The new energy mix will consist mainly of Inverter-Based Resources (IBRs), such as wind and solar power.

Dual-frames-impedance-based analysis of dynamic phase difference effect on grid-forming converter with different power synchronization controls

open access: yesInternational Journal of Electrical Power & Energy Systems
The grid-forming converters (GFMs) have been widely employed to support the power grid. Yet, the phase difference effect (PHE) caused by active power control (APC) on the system's design and stability is still inexplicable.

Freeze‐dried Lactobacillus spp. improved average daily liveweight gain and reduced methane intensity in growing lambs

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 6, Page 3857-3865, April 2026.
Abstract BACKGROUND Direct fed microbials (DFM) are natural and safe enteric methane mitigants for ruminant livestock systems. While previous studies have demonstrated the effect of Lactobacillus spp. on methane mitigation, challenges remain in effectively delivering DFM in extensive grazing systems. The objective of this experiment was to evaluate the

Effect of preoperative SGLT2 inhibitor use on postoperative acute kidney injury in patients with type 2 diabetes undergoing surgery: A causal inference study using routinely collected data

open access: yesDiabetes, Obesity and Metabolism, Volume 28, Issue 4, Page 3193-3201, April 2026.
Abstract Aims To assess whether preoperative sodium‐glucose co‐transporter 2 inhibitor (SGLT2i) use reduces the odds of postoperative acute kidney injury (AKI) in patients with type 2 diabetes undergoing surgery. Methods We conducted a target trial emulation using inverse probability of treatment weighting, utilising routinely collected data from a ...

Frequency-Voltage Active Support Strategy for Hybrid Wind Farms Based on Grid-Following and Grid-Forming Hierarchical Subgroup Control

open access: yesCSEE Journal of Power and Energy Systems
The GFL-GFM hybrid wind farm (HWF) combines the voltage source control advantages of grid-forming (GFM) wind turbines (WTs) with the current source control advantages of grid-following (GFL) wind turbines.

Improvements in Real‐World Survival in the Setting of a Recent Paradigm Shift in Acute Myeloid Leukemia Treatment

open access: yesEuropean Journal of Haematology, Volume 116, Issue 4, Page 416-424, April 2026.
ABSTRACT Therapeutic options for newly diagnosed (ND) acute myeloid leukemia (AML) have increased in recent years, leading to a shift in the treatment paradigm from conventional, intensive chemotherapy toward targeted and less intensive therapy. Since 2017, there has been a surge in FDA approvals for novel therapies, including small molecule inhibitors
