physica status solidi (b), Volume 263, Issue 3, March 2026.The formation of the transparent conductive oxide SnO2:Ta by reactive direct‐current magnetron sputtering at a low temperature of 225°C was studied as a function of the oxygen flow rate using a pilot‐scale setup. Beginning with a mixture of β‐Sn and SnO as majority phases and minority fractions of Sn3O4 and SnO2 at very low O2 flows, up to the ...

, 2012 I review two cosmological paradigms which are alternative to the current inflationary scenario. The first alternative is the "matter bounce", a non-singular bouncing cosmology with a matter-dominated phase of contraction.

Journal of Field Robotics, Volume 43, Issue 2, Page 739-760, March 2026.ABSTRACT Farmers frequently suffer from musculoskeletal disorders, particularly lower back pain (LBP), mainly due to occupational ergonomic factors such as repetitive stooping and lifting. This study proposes using an exoskeleton to reduce LBP risk by providing external torque to the hip joints.

Bouncing Cosmologies: Progress and Problems
, 2016 We review the status of bouncing cosmologies as alternatives to cosmological inflation for providing a description of the very early universe, and a source for the cosmological perturbations which are observed today.

Proposal of a novel APPLE‐KNOT undulator by selecting the KNOT field as the dominant magnetic field
Journal of Synchrotron Radiation, Volume 33, Issue 2, Page 289-297, March 2026.The degradation of circular polarization state in conventional APPLE‐KNOT undulators has been noted. To overcome this limitation, we propose a novel APPLE‐KNOT undulator design which utilizes the KNOT magnetic field as the dominant component.The APPLE‐KNOT undulator forms composite magnetic fields by superimposing an APPLE field and a KNOT field with ...

An accelerated framework for high‐resolution X‐ray holographic reconstruction
Journal of Synchrotron Radiation, Volume 33, Issue 2, Page 454-466, March 2026.HiHolo, a high‐performance CUDA‐MPI software framework for X‐ray holographic reconstruction, achieves performance improvement over existing solutions while introducing three enhanced iterative algorithms that effectively reduce artifacts and improve spatial resolution in propagation‐based phase contrast imaging.X‐ray propagation‐based phase contrast ...

Diabetes, Obesity and Metabolism, Volume 28, Issue 3, Page 2061-2074, March 2026.Abstract Aims To evaluate the accuracy of abdominal fat distribution of subcutaneous (SAT) and visceral adipose tissue (VAT) assessed by ultrasound (US) compared to magnetic resonance imaging (MRI), as the gold standard technique. Additionally, to assess the association between abdominal fat distribution measured by US and metabolic conditions in ...

Advanced Optical Materials, Volume 14, Issue 7, 16 February 2026.This work dissects the ultrafast response of polydisperse plasmonic nanorods using two‐dimensional electronic spectroscopy, uniquely combining temporal and spectral resolution. Our ultrabroadband pulses cover both transverse and longitudinal nanorods’ resonances, revealing sub‐200‐fs dynamics and distinct broadening mechanisms.

Gluon Saturation and Black Hole Criticality
, 2007 We discuss the recent proposal in hep-th/0611312 where it was shown that the critical anomalous dimension associated to the onset of non-linear effects in the high energy limit of QCD coincides with the critical exponent governing the radius of the black

Advances in Triboelectric Nanogenerators With Rotating Structure
Carbon Energy, Volume 8, Issue 2, February 2026.The rotating TENG has been widely studied for its superiorities of simple structure, high efficiency, and stable output. This review introduced the four different principles of rotating TENG and offered a thorough summary for performance and application research through three‐level classification. Importantly, the current existing problems, challenges,
