We show that for every effective left conjugacy closed left quasigroup, there is an induced rack that retains the conjugation structure of the left translations. This means that cryptographic protocols relying on conjugacy search can be secure only if conjugacy search of left translations is infeasible in the induced rack. We note that, in fact, protocols based on conjugacy search could be simp...

We designed a variable-tilt microfuge fermentation rack to screen liquid cultures of wild and mutant yeasts for ethanol production. The rack design allows for the evaluation of up to 40 cultures in the space normally required for three 125 mL Erlenmeyer flasks. Microfuge tubes containing 1.0 mL of inoculated medium were placed in the rack and incubated with shaking. This technique gave reproduc...

Ackee canners often harvest mature fruits that are placed on sun racks to complete ripening (indicated by podopening). It is unknown whether the nutrient composition of rack-ripened fruits differs from those completely ripened on trees. This study compares proximate, mineral and fatty acid composition of raw, mature arils of tree-ripened and rackripened fruits. Proximate and mineral composition...

and MS Thesis defense Date: 13th April 2009 Automatic Speech Recognition systems (ASRs) recognize word sequences by employing algorithms such as Hidden Markov Models. Given the same speech to recognize, the different ASRs may output very similar results but with errors such as insertion, substitution or deletion of incorrect words. Since different ASRs may be based on different algorithms, it i...

BACKGROUND Hong Kong is non-signatory to the 1951 Refugee Convention and its 1967 Protocol, and has no systematic domestic policies committed to the rights of asylum-seekers and refugees (ASRs). This creates a tenuous setting for African ASRs there. This study explored how mapped social determinates of health has impacted the mental health and wellbeing of African ASR's in Hong Kong. METHODS ...

BACKGROUND Opportunities for face-to-face communication with patients is increasing in modern hospital pharmacist practice. This may impose new burdens on hospital pharmacists. We performed a cross-sectional study to examine the prevalence of psychological distress, burnout, and compassion fatigue among hospital pharmacists. We also investigated possible relevant factors, such as sex, years of ...

OBJECTIVE The marked increase in the prevalence of attention-deficit/hyperactivity disorder (ADHD) among university students gives rise to questions about how best to diagnose in this setting. The aim of the present study was to calculate ADHD prevalence in a large non-clinical sample of medical students using a stepwise design and to determine whether ADHD diagnosis varies if interviewees use ...

BACKGROUND Adult attention deficit-hyperactivity disorder (ADHD) is underdiagnosed in the primary care setting despite 3% to 6% of adults having ADHD-like symptoms. The Adult ADHD Self-Report Scale-V1.1 (ASRS-V1.1) is a validated, 6-question screen for adult ADHD. Our purpose was to analyze this tool for evaluating patients in a busy primary care setting. METHODS The ASRS-V1.1 was administere...
