Investigation of photon, neutron and proton shielding features of H3BO3–ZnO–Na2O–BaO glass system

open access: yesNuclear Engineering and Technology, 2021
The current study aims to explore the shielding properties of multi-component borate-based glass series. Seven glass-samples with composition of (80-y)H3BO3–10ZnO–10Na2O–yBaO where (y = 0, 5, 10, 15, 20, 25 and 30 mol.%) were synthesized by melt-quench ...

A Monte Carlo based dose verification tool for an HDR Ir‐192 brachytherapy source and its evaluation on extremity malignancies

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background TG‐43 formalism dose calculation for brachytherapy with the homogeneous water‐based assumption is widely used, which can lead to dose inaccuracy in treatment planning. Purpose Extremity malignancies are also treated with high‐dose‐rate (HDR) 192Ir interstitial brachytherapy, a treatment site that has not been specifically ...

Gait Stability Training in a Virtual Environment Improves Gait and Dynamic Balance Capacity in Incomplete Spinal Cord Injury Patients

open access: yesFrontiers in Neurology, 2018
Many patients with incomplete spinal cord injury (iSCI) have impaired gait and balance capacity, which may impact daily functioning. Reduced walking speed and impaired gait stability are considered important underlying factors for reduced daily ...

Cross Carbonyl‐Olefin Metathesis of Unactivated Olefins

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 13, 2 July 2026.
A method for the olefination of aryl aldehydes with unactivated alkenes via cross carbonyl‐olefin metathesis is described. Reaction of an aldehyde substrate with a cis−1,2‐disubstituted or monosubstituted olefin using the HBF4 salt of 2,3‐diazabicyclo[2.2.2]octane results in high‐yielding olefination with exclusive trans stereoselectivity. The reaction
