We present an evaluation of a self-administered, biofeedback-aided, alertness training programme called the Alertness: Training for Focused Living (ATFL) Programme, which was developed as part of the Technology Research for Independent Living (TRIL) collaboration. We conducted two studies in order to evaluate the programme. A randomized controlled trial was, first of all, conducted with 40 olde...

Karger, Motwani and Sudan (JACM 1998) introduced the notion of a vector coloring of a graph. In particular they show that every k-colorable graph is also vector kcolorable, and that for constant k, graphs that are vector kcolorable can be colored by roughly k colors. Here is the maximum degree in the graph. Their results play a major role in the best approximation algorithms for coloring and fo...

Objective: To compare gender difference on renal pelvic size and urinary bladder volume (BV) in normal male and female fetuses at 37 weeks of gestational age (GA) using ultrasound. Methods: 414 normal singleton pregnancies of 37 weeks GA were included. In each fetus, antero-posterior (AP) diameter of the renal pelvis and BV was measured. Results: Male fetuses were found to have greater AP diame...

Data accumulated with a high-precision vertex drift chamber operating in the PEP detector MAC are used for a precise measurement of the lifetime of the T lepton. Results from a decay-length analysis of a sample in which one T decays into one charged particle and the other to three charged particles are combined with those from an impact-parameter analysis of an independent sample of events that...
