Long haul
Birds do it, fish do it and even some insects do it: seasonal, continent-scale migrations. Mammals appear much less adapted to move over such great distances, although whales undertake substantial annual journeys. Now new research suggests that the humpback whale of the Eastern Pacific travels further than any previously documented mammal — moving up and down the south-east Pacific. Researchers...
متن کاملLong-Haul TCP vs. Cascaded TCP
In this work, we investigate the bandwidth and transfer time of long-haul TCP versus cascaded TCP [5]. First, we discuss the models for TCP throughput. For TCP flows in support of bulk data transfer (i.e., long-lived TCP flows), the TCP throughput models have been derived [2, 3]. These models rely on the congestion-avoidance algorithm of TCP. Though these models cannot be applied with short-liv...
متن کاملTuberculosis: in it for the long haul.
Professor Brigitte Gicquel is head of the Mycobacterial Genetics unit at the Pasteur Institute in Paris, France. After completing her undergraduate and doctoral studies at the University of Paris VII, she joined the Pasteur Institute in 1973 and has spent much of her scientific career concentrating on the genetics of Mycobacterium tuberculosis. Gicquel coordinated both the European Commission's...
متن کاملOFDM in Optical Long-Haul Transmission
In this paper we review two OFDM based architectures, which have recently been proposed for optical long-haul transmission. The BER performance is investigated in presence of chromatic dispersion and differential group delay. In a further step both architectures are extended to polarization diversity receivers. Improvement is achieved by diversity combining at the expense of increased complexity.
متن کاملAngle-closure glaucoma on long-haul flights.
IMPORTANCE Unlike other modes of long-distance travel, long-haul flights delay urgent, specialist medical treatment until the destination is reached or the plane is diverted. Angle-closure glaucoma (ACG) occurring during those flights results in considerable morbidity and may cause permanent visual loss. It is preventable in patients with risk factors but may be an underrecognized and underrepo...
