A simple mathematical model for the temperature evolution in cornea exposed to short-pulsed Ho: YAG laser under Laser Thermo Keratoplasty (LTK) treatment is developed by incorporating heat flux phase-lag Fourier’s transfer and source term described Lambert Beer’s law. An analytical solution obtained using Laplace transformation technique. The computational results profile variation with time ar...

The paper presents a comparison of several hybridization between RANS and LES, and their potential and limitations in an industrial context. The first part of the paper addresses an often eluded problem in the hybrid RANS/LES community: the importance of the baseline statistical model. A new robust low-Reynolds number eddy-viscosity model, derived from a Reynolds-stress model and accounting for...

The method used in maintaining cultures of Aerobacter m o g m s affects the relationship between duration of lag phase and age of inoculum in a gludose ammonium salt medium. Organisms kept in broth may show pronounced early lag whilst those from agar slopes do not. Previous subcultivation with aeration decreases the lag. Bacteria showing no lag may do so when they have been washed ; glutamate, ...

Unlike bacteria such as Escherichia coli and Bacillus subtilis, several species of freshwater cyanobacteria are known to contain multiple chromosomal copies per cell, at all stages of their cell cycle. We have characterized the replication of multi-copy chromosomes in the cyanobacterium Synechococcus elongatus PCC 7942 (hereafter Synechococcus 7942). In Synechococcus 7942, the replication of mu...

Experimental tibial lengthening was achieved in 61 rabbits to examine the effect of continuous local infusion of recombinant human fibroblast growth factor-2 (rhFGF-2) on bone healing of the lengthened segment. The tibial diaphysis was separated by osteotomy and was subjected to slow progressive distraction (rate: 0.35 mm/12 h) using a monolateral external fixator. There were a lag phase for 1 ...

This paper proposes a new system-equation test for threshold cointegration based on a threshold vector autoregressive distributed lag (ADL) model. The new test can be applied when the cointegrating vector is unknown and when weak exogeneity fails. The asymptotic null distribution of the new test is derived, critical values are tabulated, and finite-sample properties are examined. In particular,...

This paper describes a computational model of the Attentional Blink constructed using the dual-stage model proposed by [1] and also incorporating a token based account of working memory [2]. This model reproduces data from a number of blink paradigms and makes predictions that lag-1 sparing is temporal and not sequential in origin. A further prediction is that enhancing the distinctiveness of T...

Plasminogen activation by tissue-type plasminogen activator (t-PA) is stimulated by fibrin. In a purified system maximal fibrin-enhanced plasmin formation occurs with a delay after an initial phase of slow plasmin formation (lag phase). In the present study purified stimulating CNBr-fragment FCB-2 of fibrinogen was used, and kinetics of plasminogen activation by t-PA were analyzed with respect ...
