Hard-constrained inconsistent signal feasibility problems

IEEE Transactions on Signal Processing, 47(9), 2460–2468.

author keywords: convex feasibility problem; fixed point; Hilbert space; inconsistent constraints; monotone operator; optimization; signal synthesis
TL;DR: This work considers the problem of synthesizing feasible signals in a Hilbert space in the presence of inconsistent convex constraints, and proposes a formalism and algorithmic framework that unify and extend existing approaches to inconsistent signal feasibility problems.

1999 journal article

Dynamics of Macrophage and T Cell Infection by HIV

Journal of Theoretical Biology, 196(1), 101–113.

By: D. Wodarz*, A. Lloyd*, V. Jansen* & M. Nowak*

MeSH headings : CD4-Positive T-Lymphocytes / virology; HIV / physiology; HIV Infections / immunology; HIV Infections / virology; Humans; Lymphocyte Activation; Macrophages / virology; Models, Biological; Receptors, CCR5; Receptors, CXCR4; T-Lymphocytes, Cytotoxic / immunology; Virus Integration; Virus Replication
TL;DR: Mathematical models predict that macrophage infection may be essential for the successful establishment of HIV in the primary phase of the infection, paving the way for the rise of exclusively T cell tropic strains using the CXCR4-coreceptor. (via Semantic Scholar)

HLA alleles determine human T-lymphotropic virus-I (HTLV-I) proviral load and the risk of HTLV-I-associated myelopathy

Proceedings of the National Academy of Sciences, 96(7), 3848–3853.

By: K. Jeffery*, K. Usuku*, S. Hall*, W. Matsumoto*, G. Taylor*, J. Procter*, M. Bunce*, G. Ogg* ...

MeSH headings : Alleles; Genes, MHC Class I; Genes, MHC Class II; Genetic Predisposition to Disease / immunology; HLA-A Antigens / genetics; HLA-B Antigens / genetics; HLA-DR Antigens / genetics; HLA-DRB1 Chains; HTLV-I Infections / blood; HTLV-I Infections / genetics; HTLV-I Infections / immunology; Histocompatibility Testing; Human T-lymphotropic virus 1 / immunology; Human T-lymphotropic virus 1 / isolation & purification; Humans; Paraparesis, Tropical Spastic / blood; Paraparesis, Tropical Spastic / genetics; Paraparesis, Tropical Spastic / immunology; Risk Factors; Viral Load
TL;DR: It is shown that, after infection with HTLV-I, the class I allele HLA-A*02 halves the odds of HAM/TSP, implying that an efficient antiviral CTL response can reduce virus load and so prevent disease in persistent virus infections. (via Semantic Scholar)

MeSH headings : Acquired Immunodeficiency Syndrome / mortality; Acquired Immunodeficiency Syndrome / virology; CD4 Lymphocyte Count; HIV-1 / isolation & purification; Humans; Male; Time Factors
TL;DR: This work quantitates the previously reported relationship between viral load and survival time, introduces the concept of viral constant, and presents evidence that this quantity is conserved across patients, and explores the immunopathological implications of this finding.

Structured tree outflow condition for blood flow in larger systemic arteries

American Journal of Physiology-Heart and Circulatory Physiology, 276(1), H257–H268.

By: M. Olufsen*

author keywords: arterial modeling; mathematical modeling; arterial outflow boundary condition
MeSH headings : Arteries / physiology; Blood Pressure / physiology; Humans; Models, Cardiovascular; Pulsatile Flow; Regional Blood Flow / physiology; Vascular Resistance / physiology
TL;DR: A structured tree attached to the terminal branches of the truncated arterial tree in which the root impedance is estimated using a semianalytical approach based on a linearization of the viscous axisymmetric Navier-Stokes equations provides a dynamic boundary condition that maintains the phase lag between blood flow and pressure as well as the high-frequency oscillations present in the impedance spectra.
