Performance limits for FDMA cellular systems described by hypergraphs [PDF]
, 1991 The authors present some preliminary material about hypergraphs, including a discussion of what they call random hypergraph multicolorings, a notion which is central to the analysis of frequency-assignment algorithms.

Tumor‐Associated Glycan Exploits Adenosine Receptor 2A Signaling to Facilitate Immune Evasion
Advanced Science, EarlyView.This study identifies Globo H ceramide (GHCer) as a novel immune checkpoint molecule that suppresses the activation of conventional T lymphocytes while promoting the differentiation and function of regulatory T cells. The immunosuppressive effects of GHCer are mediated through the activation of the A2AR/cAMP/PKA pathway, which involves its interactions

Traffic models for dynamic system optimal assignment [PDF]
, 2005 Most analyses on dynamic system optimal (DSO) assignment are done by using a control theory with an outflow traffic model. On the one hand, this control theoretical formulation provides some attractive mathematical properties for analysis. On the other

Advanced Science, EarlyView.The Semaphorin 3E (Sema3E)‐Plexin‐D1 pathway mediated by C/EBPα and C/EBPβ downstream of the luteinizing hormone (LH) surge plays important roles in the mouse preovulatory ovary. Timely activation and suppression of this pathway during the preovulatory stage are crucial for ovulation, corpus luteum formation, and proper angiogenesis.

Parallel optimization for traffic assignment [PDF]
Mathematical Programming, 1988 Most large-scale optimization problems exhibit structures that allow the possibility of attack via algorithms that exhibit a high level of parallelism. The emphasis of this paper is the development of parallel optimization algorithms for a class of convex, block-structured problems.
