Bit error rate computation for optical communication systems incorporating equal­ izers and under both noise and intersymbol interference (ISI) is discussed. An ac­ curate method based on a saddlepoint approximation is used for the computation. Previous work based on saddlepoint approximation has considered only the use of ba­ sic integration-and-dump detection. When ISI is strong, this simple ...

OBJECTIVE Describing the self-perceived impact on health of people living near to a solid waste disposal site in Cali and on their physical and social environments. METHODS In addition to a cohort study, qualitative research was carried out to explore experiences amongst 16 residents in leadership positions in their communities. Seven semi-structured interviews and one focus group were conduc...

In order to optimize the detection of protein-DNA contacts by DNA photoaffinity labeling, we attached four different photoreactive groups to DNA and examined their ability to crosslink yeast RNA polymerase III (Pol III) transcription complexes. Photoreactive nucleotides containing an aryl azide (AB-dUMP), benzophenone (BP-dUMP), perfluorinated aryl azide (FAB-dUMP) or diazirine (DB-dUMP) couple...

In our increasingly interconnected world, software security is an increasingly important issue for development teams. However, there is too much security work to do for these teams as security needs have out-scaled security resources. To help prioritize security efforts, professionals use the attack surface of a system, or the sum of all paths for untrusted data into and out of a system, to ide...

With the increasing development of laser accelerators, the electron energy is already beyond GeV and even higher in near future. Conventional beam dump based on ionization or radiation loss mechanism is cumbersome and costly, also has radiological hazards. We revisit the stopping power of high-energy charged particles in matter and discuss the associated problem of beam dump from the point of v...

Kdump is a kexec based kernel crash dumping mechanism, which is being perceived as a reliable crash dumping solution for Linux R ©. This paper begins with brief description of what kexec is and what it can do in general case, and then details how kexec has been modified to boot a new kernel even in a system crash event. Kexec enables booting into a new kernel while preserving the memory content...

This paper gives a randomized competitive distributed paging algorithm called Heat & Dump. The competitive ratio is logarithmic in the total storage capacity of the network, this is optimal to within a constant factor. This is in contrast to the linear optimal deterministic competitive ratio BFR].

A Bluetooth beacon-based underground navigation system (BBUNS) was developed to identify the optimal haul road in an underground mine, track the locations of dump trucks, and display this information on mobile devices. A three-dimensional (3-D) geographic information system (GIS) database of the haul roads in an underground mine was constructed, and the travel time for each section was calculat...

OBJECTIVES The aim of the study was to assess respiratory complaints in the residents of Neve Yakov following the closure of a municipal dump, operating in the neighborhood for 3 years. MATERIALS AND METHODS We carried out a cross sectional survey of 250 adult residents. Exposures to sporadic dust, measurements and estimates of diesel emissions based on traffic load were assessed. RESULTS A...
