DOI: 10.1002/acm2.13903
Abstract: Abstract Purpose The Leksell Gamma Plan Convolution algorithm (LGP‐Convolution) has not been widely adopted. This mainly stems from the higher calculated beam‐on times relative to the standard ray tracing‐based LGP‐TMR10 dose calculation algorithm. This study… read more here.

DOI: 10.1002/asna.20240140
Abstract: Shocks in novae outbursts are ubiquitous, but in symbiotic novae, they are particularly powerful, probably because of the surrounding red giant wind. The recurrent nova RS Oph is the best example of this phenomenon. The… read more here.

DOI: 10.1002/hbm.23642
Abstract: Gamma‐aminobutyric acid (GABA) and glutamate are believed to have inhibitory and exhibitory neuromodulatory effects that regulate the brain's response to sensory perception. Furthermore, frequency‐specific synchronization of neuronal excitability within the gamma band (30–80 Hz) is… read more here.
