In this paper we address the constructive controllability problem for drift-free, leftinvariant systems on nite-dimensional Lie groups with fewer controls than state dimension. We consider small ( ) amplitude, low-frequency, periodically time-varying controls and derive average solutions for system behavior. We show how the pth-order average formula can be used to construct open-loop controls f...

Well-differentiated digestive neuroendocrine tumors (NET) are a heterogeneous group of neoplasms usually associated with slow growth but a high rate of metastases, including peritoneal carcinomatosis (PC). Herein, we aimed to comprehensively review the current knowledge of PC in terms of implications for the management and prognosis of patients with NET, including the latest studies and expert ...

A small subset of patients infected with Borrelia burgdorferi (Bb) does not produce Bb specific antibody. Our research provides additional evidence of a genetic predisposition for seronegativity in some individuals with Lyme disease. Because human leukocyte antigen (HLA) class II, a heterodimeric glycoprotein, plays an essential role in the regulation of antibody production, we investigated the...

This paper investigates how rural farm households adapt to the risk of disease. In the context of malaria, adaptation brings to mind mosquito nets, sprays and coils. However, adaptation may be more subtle. For instance, households living in malaria-endemic regions may alter their crop choice to reduce their exposure to disease and the associated likelihood of crop failure. Thus the risk of mala...

This study was aimed to search genetic variants, to investigate phylogenetic relationships between pig breeds and to provide basic genetic information of Korean Native Pigs (KNP) using the variations of the Swine Leukocyte Antigen-6 (SLA-6) gene. Cloning of the Swine Leukocyte Antigen (SLA)-6 gene in the MHC non-classical region was performed with spleen tissues of Korean Native Pigs (KNP). Seq...

This paper studies the perturbation of a Lie-Poisson (or, equivalently an Euler-Poincaré) system by a special dissipation term that has Brockett’s double bracket form. We show that a formally unstable equilibrium of the unperturbed system becomes a spectrally and hence nonlinearly unstable equilibrium after the perturbation is added. We also investigate the geometry of this dissipation mechanis...

Distributed object systems provide the key to building large scale applications that can execute on a range of platforms. The Common Object Request Broker Architecture (CORBA) specification from OMG attempts to address interoperability and heterogeneity issues that arise in such systems. Our goal is to investigate performance issues for distributed object systems. We claim that object caching i...

2010 John Wiley & Sons A/S Immunological Reviews 0105-2896 Granule-mediated cytolysis is undoubtedly the most important effector function of CD8 T cells and natural killer (NK) cells. After a killer cell recognizes its target, the cytotoxic granules, which are specialized secretory lysosomes that store the death-inducing proteins, migrate to the immunological synapse (IS). The cytotoxic granule...

BACKGROUND Inadequate dermoscopy training represents a major barrier to proper dermoscopy use. OBJECTIVE To better understand the status of dermoscopy training in US residency programs. METHODS A survey was sent to 417 dermatology residents and 118 program directors of dermatology residency programs. RESULTS Comparing different training times for the same training type, residents with 1-1...
