Astrocytic Phenotypic Switching in Posterior Piriform Cortex Orchestrates Bone Cancer Pain–Depression Comorbidity via Purinergic–Noradrenergic Signaling

open access: yesAdvanced Science, EarlyView.
Bone cancer pain and depression share a common origin: astrocytic A2‐to‐A1 transition in the posterior piriform cortex. This phenotypic shift disrupts the ATP–adenosine–A2AR–norepinephrine axis, simultaneously driving nociceptive and affective dysfunction.

Orthogonal projection of a point onto the standard simplex algorithms analysis

2015 International Conference "Stability and Control Processes" in Memory of V.I. Zubov (SCP), 2015
In this paper a comparative study of the time complexity of two “fast” algorithms for projecting a point onto the standard simplex is presented. Methods of Maculan-de Paula and Malozemov-Pevnyi, as well as two modifications of Malozemov-Pevnyi are considered.

A Non-interior Point Continuation Algorithm Based on Orthogonal Projection for Second-Order Cone Programming

2009 Fifth International Conference on Natural Computation, 2009
Based on orthogonal projection, a non-interior point continuation algorithm for second-order cone programming problems is proposed and analyzed. The main idea of the method is that we reformulate the complementary condition in the optimality conditions as a projection equation.
