The reaction force and the electronic flux, first proposed by Toro-Labbé et al. (J Phys Chem A 103:4398, 1999) have been expressed by the existing conceptual DFT apparatus. The critical points (extremes) of the chemical potential, global hardness and softness have been identified by means of the existing and computable energy derivatives: the Hellman-Feynman force, nuclear reactivity and nuclea...

This report mainly discusses the adaptability of the IRC-based Bot detection method to be used in the P2P-based Bot detection. The first section introduces the IRC-based bot and the newly appeared P2P-based bot to see their difference. The second section shows the related work and the traditional method of BOTNET detection. The third section discusses the methodology used by the IRC based Botne...

To further cybersecurity, there is interest in studying online cybercriminal communities to learn more about emerging cyber threats. Literature documents the existence of many online Internet Relay Chat (IRC) cybercriminal communities where cybercriminals congregate and share hacking tools, malware, and more. However, many cybercriminal community participants appear unskilled and have fleeting ...

Adsorption and regeneration of ion exchange resins were studied using a subcritical solution of a CO2-H2O mixture and a fixed bed column. The commercial Amberlite IRC-50/IRC-86 cation exchange resins and Amberlite IRA-67 anion exchange resin were tested for heavy metals (Pb, Cu, Cd) adsorption from a solution with different initial metal concentrations at different temperatures. After adsorptio...

OBJECTIVE Executive dysfunction after traumatic brain injury (TBI) in children is common and leads to significant problems in functioning across multiple settings. The objective of this study was to evaluate the efficacy of a web-based counselor-assisted problem solving (CAPS) intervention compared with an Internet resource comparison (IRC) for treatment of executive dysfunction within 12 month...

This paper analyzes portfolio risk and volatility in the presence of constraints on portfolio rebalancing frequency. This investigation is motivated by the incremental risk charge (IRC) introduced by the Basel Committee on Banking Supervision. In contrast to the standard market risk measure based on a 10-day value-at-risk calculated at 99% confidence, the IRC considers more extreme losses and i...

Lumbar artificial implants/disks experiment material deformations during the biomechanical loads/movements that are acting dynamically on the lumbar spine, e.g., flexion, extension, lateral flexion and torsion. During this biomechanical process disks and vertebras, (each spine part as a whole in general) move around an Instantaneous Rotation Center (IRC, 3D) or an Instantaneous Axis of Rotation...

Much attention has been devoted recently to the underground economy, and in particular to the IRC markets for stolen identities, phishing kits, botnets, and cybercrime related services. It is suggested that sophisticated underground markets show great specialization and maturity. There are complex divisions of labor and service offerings for every need. Stolen credentials are traded in bulk for...

The design of Internet Relay Chat (IRC) affords for, and itself produces, non-response situations that are not possible in FTF or telephone interaction. These system-occasioned non-responses produce almost isomorphic stimuli to participant non-responses. Situations thus arise in which nonresponses are interpersonally accountable despite agentive ambiguity. This study explores four intersections...
