Auditing system logs is an important means of ensuring systems’ security in situations where run-time security mechanisms are not sufficient to completely prevent potentially malicious activities. A fundamental requirement for reliable auditing is the integrity of the log entries. This paper presents an infrastructure for secure logging that is capable of detecting the tampering of logs by powe...

ISSUE ADDRESSED Overseas research shows that fatality and injury risks per cyclist and pedestrian are lower when there are more cyclists and pedestrians. Do Australian data follow the same exponential 'growth rule' where (Injuries)/(Amount of cycling) is proportional to ((Amount of cycling)-0.6)? METHOD Fatality and injury risks were compared using three datasets: 1) fatalities and amounts of...

OBJECTIVES To investigate the effect of three cycling cadences on a subsequent 3000 m track running performance in well trained triathletes. METHODS Nine triathletes completed a maximal cycling test, three cycle-run succession sessions (20 minutes of cycling + a 3000 m run) in random order, and one isolated run (3000 m). During the cycling bout of the cycle-run sessions, subjects had to maint...

Abstract The potential application of a 50 ?m thick anion exchange membrane prepared based on poly(terphenyl piperidinium-co-trifluoroacetophenone) (PTPT) is investigated for vanadium redox flow batteries (VRFBs). PTPT exhibits considerably lower permeation than Nafion 212. Therefore, the self-discharge duration VRFB much longer Besides, shows oxidative stability almost as good 212 during immer...

With the development of information and communications technology, user-generated content and crowdsourced data are playing a large role in studies of transport and public health. Recently, Strava, a popular website and mobile app dedicated to tracking athletic activity (cycling and running), began offering a data service called Strava Metro, designed to help transportation researchers and urba...

Eating Staph he scavenger receptor CD36 is required for binding and internalization of Staphylococcus aureus , report Stuart et al. (page 477). After recognizing lipoteichoic acid on the bacterial surface, CD36 teams up with toll-like receptors, TLR2/6, to trigger expression of pro-inflammatory cytokines. Researchers already knew that CD36 recognized apoptotic cells in both mammals and flies. I...

OBJECTIVE To investigate adaptive changes in bone and muscle parameters in the paralysed limbs after detraining or reduced functional electrical stimulation (FES) induced cycling following high-volume FES-cycling in chronic spinal cord injury. SUBJECTS Five subjects with motor-sensory complete spinal cord injury (age 38.6 years, lesion duration 11.4 years) were included. Four subjects stopped...

To the Editor: Ghaemi et al 1 describe a randomized study as part of the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD) initiative in which euthymic patients were randomly assigned to continuation versus discontinuation of their antidepressant, but not " mood-stabilizing, " medications and were followed up to 3 years. The rather " eye-popping " result and conclusion, re...
