BACKGROUND Specialisation in spinal services has lead to a low threshold for referral of cervical spine injuries from district general hospitals. We aim to assess the capability of a district general hospital in providing the halo vest device and the expertise available in applying the device for unstable cervical spine injuries prior to transfer to a referral centre. METHODS The study was a ...

With concerns growing about the future security of RSA, D&H and ECDSA public key algorithms, it is argued that collision-resistant hash functions and stream ciphers with complex irregular structures that accept double key lengths are secure against quantum based computing attacks [1]. As a multi-function cipher that includes collision-resistant hash functionality, VEST can be deployed with less...

This paper demonstrates operation of the authenticated encryption mode in VEST ciphers. All VEST ciphers operating in the authenticated encryption mode with infinite error propagation provide keyed message authentication at the same speed as their keystream generation, with negligible overhead and maintaining their security ratings.

OBJECTIVE This study examined the effectiveness of using a weighted vest for increasing attention to a fine motor task and decreasing self-stimulatory behaviors in preschool children with pervasive developmental disorders (PDD). METHOD Using an ABA single-subject design, the duration of attention to task and self-stimulatory behaviors and the number of distractions were measured in five presc...

A recent concern in hazardous materials containment, removal, and military operations has been the heat and work stress imposed on personnel wearing chemical and biological protective clothing (Chemical and Biological Protection Suit, Carbon Sphere #8415-01-333-7578 and gas maskkowl, MSA91J012-013; CBR). Several microclimate-cooling systems have been tested as possible solutions (1). Although t...

OBJECTIVE In this pilot study, we determined the effectiveness of a weighted vest on attention to task for second-grade general education students with difficulty attending. METHOD We used an intervention and a control group and an ABA design to compare participants' percentage of time on task with and without a vest. Ten participants from nine elementary schools in a suburban Texas school di...

OBJECTIVE To report the efficacy of conservative treatment with cervical traction and immobilisation with a Halo vest, in two consecutive rheumatoid arthritis patients with progressive cervical myelopathy caused by subaxial subluxation. METHODS Description of neurological symptoms and signs and findings in plain radiography (PR) and magnetic resonance imaging (MRI) of the cervical spine befor...

OBJECTIVE. In this study, we examined the effectiveness of using weighted vests for improving attention, impulse control, and on-task behavior in children with attention deficit hyperactivity disorder (ADHD). METHOD. In a randomized, two-period crossover design, 110 children with ADHD were measured using the Conners' Continuous Performance Test-II (CPT-II) task. RESULTS. In the weighted vest co...
