Enhancing CBCT-based CT synthesis using planning MRI in adaptive proton therapy for head cancer: A deep learning approach. [PDF]
J Appl Clin Med PhysAbstract Background Proton therapy (PT) is recognized as a superior treatment for head cancer (HC) due to its precision and minimal damage to surrounding healthy tissues, relying on computed tomography (CT) data for dose calculations. Adaptive proton therapy (APT) is crucial to address changes in patient anatomy during treatment and update dose ...

Comparative Study of Iminodibenzyl and Diphenylamine Derivatives as Hole Transport Materials in Inverted Perovskite Solar Cells. [PDF]
ChemistryThis study introduces novel fluorene‐based hole transport materials (HTMs) for perovskite solar cells (PSCs), integrating iminodibenzyl and diphenylamine moieties. These materials exhibit remarkable photostability, optical, and thermal properties. Among them, TDF‐2 achieved a power conversion efficiency (PCE) of 19.38 %.

Location and Concentration of Aromatic-Rich Segments Dictates the Percolating Inter-Molecular Network and Viscoelastic Properties of Ageing Condensates. [PDF]
Adv Sci (Weinh), 2023 Biomolecular condensates importantly contribute to the spatiotemporal organization of the cell. However, condensates can age over time transitioning into gel‐like pathological aggregates. Here, by combining atomistic and coarse‐grained simulations, the authors investigate how the concentration and location of low‐complexity aromatic‐rich kinked ...

Formation of hollow silver nanoparticles under irradiation with ultrashort laser pulses. [PDF]
NanophotonicsAbstract We have studied the formation of cavities in spherical silver nanoparticles embedded in silica, irradiated with fs laser pulses that produce an intense electronic excitation. Experimentally determined aspect ratio, i.e. the ratio between the cavity and nanoparticle size, for hollow structures formed under different irradiation conditions shows

An Adversarial Risk Analysis Framework for Cybersecurity
Risk Analysis, Volume 41, Issue 1, Page 16-36, January 2021., 2021 Abstract Risk analysis is an essential methodology for cybersecurity as it allows organizations to deal with cyber threats potentially affecting them, prioritize the defense of their assets, and decide what security controls should be implemented. Many risk analysis methods are present in cybersecurity models, compliance frameworks, and international ...

Abstract and Applied Analysis, Volume 2015, Issue 1, 2015., 2015 Synapses are key elements in the information transmission in the nervous system. Among the different approaches to study them, the use of computational simulations is identified as the most promising technique. Simulations, however, do not provide generalized models of the underlying biochemical phenomena, but a set of observations, or time‐series ...
