Mass-sensing BioCD Protein Array towards Clinical Application: Prostate Specific Antigen Detection in Patient Sera [PDF]

arXiv, 2009
Mass-sensing biosensor arrays for protein detection require no fluorophores or enzyme labels. However, few mass biosensor protein arrays have demonstrated successful application in high background samples, such as serum. In this paper, we test the BioCD as a mass biosensor based on optical interferometry of antibodies covalently attached through Schiff-

An upper bound on the algebraic connectivity of regular graphs [PDF]

arXiv, 2015
We derive a new upper bound on the algebraic connectivity of a regular graph using the Higman-Sims technique. Together with a new result on the connectivity of the neighbourhood graph of strongly regular graphs, our result gives a characterization of a class of strongly regular graphs that maximize the algebraic connectivity amongst regular graphs.

Canonical immunity and genericity [PDF]

arXiv, 2017
Whereas the usual notions of immunity -- e.g., immunity, hyperimmunity, etc. -- are associated with Cohen genericity, canonical immunity, as introduced by Beros, Khan and Kjos-Hanssen, is associated instead with Mathias genericity. Specifically, every Mathias generic is canonically immune and no Cohen 2-generic computes a canonically immune set.

Artificial Immune Privileged Sites as an Enhancement to Immuno-Computing Paradigm [PDF]

arXiv, 2011
The immune system is a highly parallel and distributed intelligent system which has learning, memory, and associative capabilities. Artificial Immune System is an evolutionary paradigm inspired by the biological aspects of the immune system of mammals. The immune system can inspire to form new algorithms learning from its course of action.

Mathematical models for vaccination, waning immunity and immune system boosting: a general framework [PDF]

arXiv, 2015
When the body gets infected by a pathogen or receives a vaccine dose, the immune system develops pathogen-specific immunity. Induced immunity decays in time and years after recovery/vaccination the host might become susceptible again. Exposure to the pathogen in the environment boosts the immune system thus prolonging the duration of the protection ...

Anti-pig Antibodies in Swine Veterinarian Serum: Implications for Clinical Xenotransplantation [PDF]

arXiv
Recent clinical xenotransplantation and human decedent studies demonstrate that clinical hyperacute rejection of genetically engineered porcine organs can be reliably avoided but that antibody mediated rejection continues to limit graft survival.

Towards a Conceptual Framework for Innate Immunity [PDF]

Proceedings of the 4th International Conference on Artificial Immune Systems (ICARIS 2005), Lecture Notes in Computer Science 3627, Banff, Canada, p 112-125, 2010
Innate immunity now occupies a central role in immunology. However, artificial immune system models have largely been inspired by adaptive not innate immunity. This paper reviews the biological principles and properties of innate immunity and, adopting a conceptual framework, asks how these can be incorporated into artificial models.

Epidemic spreading with immunization rate on complex networks [PDF]

arXiv, 2011
We investigate the spread of diseases, computer viruses or information on complex networks and also immunization strategies to prevent or control the spread. When an entire population cannot be immunized and the effect of immunization is not perfect, we need the targeted immunization with immunization rate.

Two novel immunization strategies for epidemic control in directed scale-free networks with nonlinear infectivity [PDF]

arXiv, 2018
In this paper, we propose two novel immunization strategies, i.e., combined immunization and duplex immunization, for SIS model in directed scale-free networks, and obtain the epidemic thresholds for them with linear and nonlinear infectivities. With the suggested two new strategies, the epidemic thresholds after immunization are greatly increased. For

Higher order approximations in arcsine laws for subordinators [PDF]

arXiv
We establish higher order approximations in the Dynkin--Lamperti theorem, a limit theorem for the distribution of a killed subordinator immediately before its first passage time over a fixed level. For this purpose, we also study asymptotic expansions of potential densities for killed subordinators.
