hyperleukocytosis is an oncological emergency but is extremely rare in non-malignant conditions. nucleated rbcs give rise to spuriously high total leucocyte count and cause clinical dilemma. thalassemia major patients are known to have leucocytosis even after correction for nucleated rbcs. we report a case of undiagnosed thalassemia major in a 4 month old infant with total leucocyte count highe...

A method is presented to divide the measured total congestion in any freeway section into three ‘slices’: (1) the delay that collisions cause; (2) the potential reduction in delay at bottlenecks that ideal ramp metering can achieve; and (3) the remaining delay, due mainly to excess demand, but also to all other causes, including non-collision incidents, lane closures, and weather. The method in...

OBJECTIVE To systematically review Indian literature on delays in tuberculosis (TB) diagnosis and treatment. METHODS We searched multiple sources for studies on delays in patients with pulmonary TB and those with chest symptoms. Studies were included if numeric data on any delay were reported. Patient delay was defined as the interval between onset of symptoms and the patient's first contact ...

Publishing in scholarly peer-reviewed journals causes long delays from submission to its subsequent publication. This may be due to the long peer-review process or backlog of manuscripts waiting in line in the journals. The present study examines the publication delay in 13 journals published by CSIR-NISCAIR at three different stages. These were delays between receipt of manuscript and its revi...

The effectiveness of Variable Messages Signs (VMS) on route guidance is assessed by a discrete probit choice model that estimates the proportion of vehicles that diverts to an alternative routes given the characteristics of different messages. A before–and–after study is also conducted to quantitatively evaluate the network wide reduction of travel time and total delay of VMS systems. We find t...

We consider the fundamental delay bounds for scheduling packets in an N × N packet switch operating under the crossbar constraint. Algorithms that make scheduling decisions without considering queue backlog are shown to incur an average delay of at least O(N). We then prove that O(log(N)) delay is achievable with a simple frame based algorithm that uses queue backlog information. This is the be...

Optical all-pass filters, which generate strong on-resonance optical delay while maintaining a unity transmission coefficient throughout the entire resonant bandwidth, are of great importance for constructing delay lines in optical buffer applications. We provide an analysis of optical delay lines based upon cascading multiple stages of all-pass filter structures. We show that the maximum capac...
