The lacE and lacG genes from Streptococcus mutans have been isolated and characterized, and their nucleotide sequence has been determined. The lacE gene encodes the lactose-specific Enzyme II component of the phosphoenolpyruvate-dependent phosphotransferase system (PTS). The lacG gene encodes the phospho-beta-galactosidase which cleaves the lactose phosphate that is formed by the lactose PTS. T...

1. Environmental heterogeneity created by prescribed burning provided the context for testing whether the distribution of an oak specialist (the lace bug, Corythuca arcuata ) could be explained by stoichiometric mismatches between herbivore and host plant composition. 2. Field observations showed that lace bug density was seven-fold higher in frequently burned than in unburned units. 3. Lace bu...

INTRODUCTION interventions to prevent hospital readmission depend on the identification of patients at risk. The LACE index predicts readmission (and death) and is in clinical use internationally. The LACE index was investigated in an older UK population. METHODS randomly selected alive-discharge episodes were reviewed. A LACE score was calculated for each patient and assessed using receiver ...

Background. Rugby ::::::union:::::: is a team sport with a high amount of physical contact during match play. The physical performance and anthropometric characteristics required, differ based on the playing position. Objectives. The objective of this systematic review was to relate anthropometric properties with physical performance parameters in Rugby ::::::union:::::: backs and forwards acr...

Unplanned readmissions may be avoided by accurate risk prediction and appropriate resources could be allocated to high risk patients. The Length of stay, Acuity of admission, Charlson comorbidity index, Emergency department visits in past six months (LACE) index was developed to predict hospital readmissions in Canada. In this study, we assessed the performance of the LACE index in a Singaporea...

Stress and vigor are endpoints on a continuum of the suitability of plants for insect herbivores. Senescence-feeding insects, such as the chrysanthemum lace bug, Corythucha marmorata (Uhler) (Hemiptera: Tingidae, Tingitini), are hypothesized to benefit from any stressor hastening the senescence of plant tissues, such as drought. They are also hypothesized to prefer feeding and ovipositing on st...

Wireless link correlation has shown significant impact on the performance of various sensor network protocols. Many works have been devoted to exploiting link correlation for protocol improvements. However, the effectiveness of these designs heavily relies on the accuracy of link correlation measurement. In this paper, we investigate state-of-the-art link correlation measurement and analyze the...

We give an introduction to the lace expansion for self-avoiding walks, with emphasis on self-avoiding polygons, and with a focus on combinatorial rather than analytical aspects. We derive the lace expansion for self-avoiding walks, and show that this is equivalent to taking the reciprocal of the self-avoiding walk generating function. We list some of the rigorous results for self-avoiding walks...

BACKGROUND The LACE index was designed to predict early death or unplanned readmission after discharge from hospital to the community. However, implementing the LACE tool in real time in a teaching hospital required practical unavoidable modifications. OBJECTIVE The purpose of this study was to validate the implementation of a modified LACE index (LACE-rt) and test its ability to predict read...
