Modern-day attackers tend to use sophisticated multi-stage/multi-host attack techniques and anti-forensics tools to cover their attack traces. Due to the limitations of current intrusion detection and forensic anal­ ysis tools, reconstructing attack scenarios from evidence left behind by the attackers of an enterprise system is challenging. In particular, re­ constructing attack scenarios by us...

I n 1994, 38% of hospi ta l s su rveyed ind ica t ed plans for future workforce cuts. Twenty-seven percen t of these hospi ta l s i nd ica t ed they are t a rge t ing nurses, compared wi th only 19% in 1993.1 Professional nurs ing staff cuts are not just a resul t of dec reased need or inc reased efficiency: 50% of the nurses whose jobs are e l imina ted are be ing rep laced wi th un l i censed...

lenge to system designers. Portable systems, such as laptop computers and personal digital assistants (PDAs), draw power from batteries, so reducing power consumption extends their operating times. For desktop computers or servers, high power consumption raises temperature and deteriorates performance and reliability. Soaring energy prices early last year and rising concern about the environmen...

Date of publication: 8 October 2012 The Fastest Mobile Microrobots in the World R ecent advances in micro/nanotechnologies and microelectromechanical systems have enabled micromachined mobile agents. Highly dynamic mobile microrobots are believed to open the gate for various future applications. However, at the submillimeter scale, the adhesion effects dominate physics, especially in the air en...

In recent decades, studying order statistics arising from independent and not necessary identically distributed (INID) random variables has been a main concern for researchers. A cumulative distribution function (CDF) of these random variables (Fi:n) is a complex manipulating, long time consuming and a software-intensive tool that takes more and more times. Therefore, obtaining approximations a...

A rabbit lymphocyte-mouse myeloma hybrodoma (RX54-3) was administered to BALB/c mice, in order to determine whether hybridoma cells have any protective effect on the tumorigenicity of the P3X63/Ag8 mouse myeloma cell line, one of the parents of this hybridoma. Two sublines of RX54-3 were studied, (a) "new" cells, which produce rabbit light chains and mouse immunoglobulin, are killed by anti-mye...

This paper analyzes an effective technique for stabilizing pure explicit time dif­ ferencing in the numerical computation of multidimensional nonlinear parabolic equations. The method uses easily synthesized linear smoothing operators at each time step to quench the instabil­ ity. Smoothing operators based on positive real powers of the negative Laplacian are helpful, and (−Δ)p can be realized ...

The induction of tumor-specific T-cell responses that are effective in eradicating disseminated tumors and in mounting a persistent tumorprotective immunity is one of the major goals of tumor immunotherapy. Here, we demonstrate that we achieved this goal by directing interleukin 2 (IL-2) to the tumor microenvironment of colon carcinoma métastases in syngeneic mice with a recombinant antibody-I...

Plants from a handful of species provide the primary source of food for all people, yet this source is vulnerable to multiple stressors, such as disease, drought, and nutrient deficiency. With rapid population growth and climate uncertainty, the need to produce ...
