Stimulus selection based on the maximum Fisher information (MFI) principle enables efficient estimation of participant parameters cognitive models with elaborated experimental tasks. However, in typical applications, a single model is assumed to be true, whereby uncertainty ignored, causing poor performance MFI-based stimulus selection. To address this problem, study proposes model-averaged MFI...

Neurons in the visual cortex code relative changes in illumination (contrast) and adapt their sensitivities to the visual scene by centering the steepest regions of their sigmoidal contrast response functions (CRFs: spike rate as a function of contrast) on the prevailing contrast. The influence of this contrast gain control has not been reported at nonoptimal drift rates. We calculated the Fish...

The high silica Mn-substituted MFI metallosilicate catalyst with Si/Al molar ratio of 220 and Si/Mn molar ratio of 50 was successfully synthesized by hydrothermal method. The catalyst sample was appropriately characterized by XRD, FE-SEM, EDX and BET techniques. The Mn-substituted MFI metallosilicate has not been reported as the potential catalyst for the methanol to propylene (MTP) reaction. T...

Reduced expression of the ab T-cell antigen receptor by alveolar T-cells. E. Yamaguchi, A. Itoh, K. Furuya, N. Hizawa, N. Ohnuma, N. Kodama, J. Kojima, Y. Kawakami. #ERS Journals Ltd 1999. ABSTRACT: A previous study revealed that reduced expression (modulation) of the CD3 antigen is a common characteristic of alveolar T-cells in health and disease. As CD3 molecules are noncovalently bound to T-...

BACKGROUND Chronic hepatitis B (CHB) patients display Toll-like receptor 9 (TLR9)-dependent defective immune responses. We aimed to study TLR9 expression on CHB patients and its alteration during therapy. METHODS We compared TLR9 expression on fresh peripheral CD14+ monocytes from a cohort of 97 CHB patients and 35 HBsAg-negative, anti-HCV-negative controls, during pegylated interferon or ent...

BACKGROUND AND OBJECTIVES Residual platelet reactivity in patients who are taking clopidogrel is commonly measured with VerifyNow assay, which is based on the principle of light transmission aggregometry. However, to evaluate the residual platelet reactivity, it would be more accurate if the reactivity of platelet glycoprotein (GP) IIb/IIIa is directly monitored. In this study, PAC1, a monoclon...

BACKGROUND Sensitization to human leukocyte antigen (HLA) from red blood cell (RBC) transfusion is poorly quantified and is based on outdated, insensitive methods. The objective was to evaluate the effect of transfusion on the breadth, magnitude and specificity of HLA antibody formation using sensitive and specific methods. METHODS Transfusion, demographic and clinical data from the US Renal ...
