[Purpose] The purpose of this study was to evaluate the functioning, extent of activity, and participation of school-aged children with cerebral palsy (CP) using the Manual Ability Classification System (MACS). [Subjects and Methods] The Subjects were 57 school-aged children (7-12 years old) with CP. The MACS, Gross Motor Function Measure (GMFM), International Classification of Functioning, Dis...
This paper gives a survey of attacks on Message Authentication Codes (MACs). First it defines the required security properties. Next it describes generic forgery and key recovery attacks on MACs. Subsequently an overview is presented of most MAC constructions and on attacks on these algorithms. The MACs described include CBC-MAC and its variants, the MAC algorithms derived from cryptographic ha...
Background: Selection of human spermatozoa prior to assisted reproduction is currently based on motility and morphology. Recently, Zeta method has been introduced for normal sperm selection based on sperm surface charges. In addition, one of the features of apoptosis is the externalization of phosphatidylserine (PS), which are normally present on the inner leaflet of the sperm plasma membrane. ...
OBJECTIVE To review the incidence of respiratory conditions and their effect on mortality in HIV-infected and uninfected individuals prior to and during the era of highly active antiretroviral therapy (HAART). DESIGN Two large observational cohorts of HIV-infected and HIV-uninfected men (Multicenter AIDS Cohort Study [MACS]) and women (Women's Interagency HIV Study [WIHS]), followed since 198...
Among various cryptographic schemes, CBC-based MACs belong to the few ones most widely used in practice. Such MACs iterate a blockcipher EK in the so called Cipher-Block-Chaining way, i.e. Ci = EK(Mi⊕Ci−1) , offering high efficiency in practical applications. In the paper, we propose a new deterministic variant of CBC-based MACs that is provably secure beyond the birthday bound. The new MAC 3kf...
Interleukin (IL)-15 is a pleiotropic immunomodulatory and anti-apoptotic cytokine. It stimulates the proliferation survival of key immunocytes including macrophages (MACs) invariant natural killer T (iNKT) cells, which are immunoinhibitory via IL-10 release clinically relevant in interferon gamma (IFNγ)-mediated inflammatory skin diseases such as alopecia areata. Using immunofluorescence micros...
In cryptography, secure channels enable the confidential and authenticated message exchange between authorized users. A generic approach of constructing such channels is by combining an encryption primitive with an authentication primitive (MAC). In this work, we introduce the design of a new cryptographic primitive to be used in the construction of secure channels. Instead of using general pur...
To explore possible mechanisms by which complement membrane attack complexes (MAC) that are deposited in the glomerular mesangium might be pathogenic, we stimulated rat glomerular mesangial cells grown in vitro with nascent MACs formed from the purified human complement components C5b6 and normal human serum and measured production of superoxide ion (O2-) and hydrogen peroxide (H2O2). Mesangial...
This study analyzes how Management Accounting and Control Systems (MACS) facilitate the appropriation of the benefits of sustainable innovations in organizations. In particular, this paper examines the moderating role of different types of MACS in the relationships between sustainable innovation and international performance at an organizational level. We collected survey data from 123 Spanish ...
