Published in 2022 at "Journal of Applied Clinical Medical Physics"

DOI: 10.1002/acm2.13562

Abstract: Abstract A multileaf collimator (MLC), virtual‐cone treatment technique has been commissioned for trigeminal neuralgia (TGN) at Tri‐Cities Cancer Center (TCCC). This novel technique was initially developed at the University of Alabama in Birmingham (UAB); it… read more here.

Published in 2022 at "Journal of Comparative Neurology"

DOI: 10.1002/cne.25423

Abstract: The retinas of fishes often have single and double cone photoreceptors that are organized in lattice‐like mosaics. In flatfishes experiencing eye migration (i.e., the metamorphic process whereby one eye migrates to the other side of… read more here.

Published in 2019 at "Medical Physics"

DOI: 10.1002/mp.13365

Abstract: PURPOSE Scatter contamination constitutes a dominant source of degradation of image quality in cone-beam computed tomography (CBCT). We have recently developed an analytic image reconstruction method with a scatter correction capability from the partially blocked… read more here.

Published in 2023 at "Medical physics"

DOI: 10.1002/mp.16435

Abstract: BACKGROUND Stereotactic radiosurgery (SRS) relies on small fields to ablate lesions. Currently, linac based treatment is delivered via circular cones using a 6 MV beam. There is interest in both lower energy photon beams, which… read more here.

Published in 2018 at "Networks"

DOI: 10.1002/net.21820

Abstract: Let G be a directed acyclic graph with n arcs, a source s and a sink t. We introduce the cone K of flow matrices, which is a polyhedral cone generated by the matrices $\vec{1}_P\vec{1}_P^T\in\RR^{n\times… read more here.

Published in 2018 at "Advances in experimental medicine and biology"

DOI: 10.1007/978-3-319-75402-4_63

Abstract: In humans cone photoreceptors are responsible for high-resolution colour vision. A variety of retinal diseases can compromise cone viability, and, at present, no satisfactory treatment options are available. Here, we present data towards establishing a… read more here.

Published in 2018 at "Journal of High Energy Physics"

DOI: 10.1007/jhep05(2018)005

Abstract: A bstractWe determine the explicit universal form of the entanglement and Renyi entropies, for regions with arbitrary boundary on a null plane or the light-cone. All the entropies are shown to saturate the strong subadditive… read more here.

Published in 2018 at "manuscripta mathematica"

DOI: 10.1007/s00229-018-1098-9

Abstract: The $${{\,\mathrm{GL}\,}}(V)$$ GL ( V ) -orbits in the enhanced nilpotent cone $$V\times \mathcal {N}$$ V × N are (essentially) in bijection with the orbits of a certain parabolic $$P\subseteq {{\,\mathrm{GL}\,}}(V)$$ P ⊆ GL (… read more here.
