BACKGROUND Apathy is a common neuropsychiatric symptom in Alzheimer's disease (AD) dementia and mild cognitive impairment (MCI). Detecting apathy accurately may facilitate earlier diagnosis of AD. The Apathy Evaluation Scale (AES) is a promising tool for measurement of apathy in prodromal and possibly preclinical AD. OBJECTIVE To compare the three AES sub-scales - subject-reported (AES-S), in...

The Advanced Encryption Standard (AES) is the Federal Information Processing Standard for symmetric encryption. It is widely believed to be secure and efficient, and is therefore broadly accepted as the standard for both government and industry applications. If fact, almost any new protocol requiring symmetric encryption supports AES, and many existing systems that were originally designed with...

This paper demonstrates complete AES key recovery from known-plaintext timings of a network server on another computer. This attack should be blamed on the AES design, not on the particular AES library used by the server; it is extremely difficult to write constant-time high-speed AES software for common general-purpose computers. This paper discusses several of the obstacles in detail.

In 2002, Murphy and Robshaw introduced an extension BES of AES and argued this could compromise the security of AES. We introduce here two block-ciphers CES and Big-BES that are some extensions of the AES and BES respectively in the spirit of Hensel lifting extensions. They are defined similarly to the AES respectively BES except that every operations are performed in a ring structure including...

In this paper, we revisit meet-in-the-middle attacks on AES in the single-key model and improve on Dunkelman, Keller and Shamir attacks of Asiacrypt 2010. We present the best attack on 7 rounds of AES-128 where data/time/memory complexities are below 2. Moreover, we are able to extend the number of rounds to reach attacks on 8 rounds for both AES-192 and AES-256. This gives the best attacks on ...

BACKGROUND Data on medication adverse effects (AEs) in chronic heart failure (CHF) are primarily based on results from clinical trials. Little is known about AEs perceived by CHF patients in daily practice and how patients deal with these subjective AEs. AIMS To describe the scope and nature of perceived AEs of CHF patients, their coping strategies and the relationship of perceived AEs to med...

Background Mild to moderate adverse events (AEs) are common after treatment of lymphatic filariasis (LF) and pose a major challenge for the global LF elimination program. We studied changes in cytokine levels and filarial worm components in plasma of subjects with and without AEs following treatment of LF. Methods Participants (n = 24) were hospitalized and monitored for AEs following treatme...

PURPOSE To assess the incidence and severity of adverse events (AE) associated with cardiovascular magnetic resonance (CMR) in a large cohort of patients with congenital heart disease and to identify independent risk factors for their occurrence. METHODS AEs were prospectively recorded from October 2002 through December 2004 and graded by 3 independent observers for severity, preventability, ...

Advanced Encryption Standard (AES) was issued as FIPS by NIST as a successor to data encryption standard (DES) algorithms. The applications of the AES are wide including any sensitive data requires cryptographic protection before communication or storage. Thus, many students are interested in learning how the AES is working. One of the inherent limitations of traditional methods for explaining/...

OBJECTIVES To describe the implementation of a trigger tool in Sweden and present the national incidence of adverse events (AEs) over a 4-year period during which an ongoing national patient safety initiative was terminated. DESIGN Cohort study using retrospective record review based on a trigger tool methodology. SETTING AND PARTICIPANTS Patients ≥18 years admitted to all somatic acute car...
