We present a generic scheme for the declarative debugging of functional logic pro-grams which is valid for eager as well as lazy programs. In particular we showthat the framework extends naturally some previous work and applies to the mostmodern lazy strategies, such as needed narrowing. First we associate to our pro-grams a semantics based on a (continuous) immediate consequenc...

A search of more than 3,000 square degrees of high latitude sky by the Sloan Digital Sky Survey has yielded 251 faint high-latitude carbon stars (FHLCs), the large majority previously uncataloged. We present homogeneous spectroscopy, photometry, and astrometry for the sample. The objects lie in the 15.6 < r < 20.8 range, and exhibit a wide variety of apparent photospheric temperatures, ranging ...

Using a nearest neighbor analysis, we construct a sample of void galaxies from the Sloan Digital Sky Survey (SDSS) and compare the photometric properties of these galaxies to the population of non-void (wall) galaxies. We trace the density field of galaxies using a volume-limited sample with zmax = 0.089. Galaxies from the flux-limited SDSS with z ≤ zmax and fewer than three volume-limited neig...

BACKGROUND Neisseria meningitidis causes 500 000 cases of septicemia and meningitis worldwide annually, with approximately 200 cases in Canada each year. Previous studies describe a case-fatality rate of 5%-15% and up to 20% of survivors suffering from long-term disability. METHODS This study was performed in Canada between 2002 and 2011; the study area included >50% of the country's populati...

Models of brown dwarf atmospheres suggest they exhibit complex physical behaviour. Observations have shown that they are indeed dynamic, displaying small photometric variations over timescales of hours. Here I report results of infrared (0.95–1.64 µm) spectrophotometric monitoring of four field L and T dwarfs spanning timescales of 0.1–5.5 hrs, the goal being to learn more about the physical na...

OBJECTIVES (1) To report the clinical and synovial effects of a platelet-rich product (PRPr) in normal equine joints, (2) to assess the persistence of platelets within synovial fluid after intra-articular injection, (3) to compare responses to different preparations of that product, and (4) to evaluate a gravity filtration system for PRPr preparation in horses. STUDY DESIGN Experimental. ME...

PURPOSE Previous studies have identified novel genetic variants associated with age at menarche in females of European descent. The pubertal growth effects of these variants have not been carefully evaluated in non-European descent groups. We aimed to examine the effects of 31 newly identified menarche-related single-nucleotide polymorphisms (SNPs) on growth outcomes in African-American (AA) an...

BACKGROUND Intranasal administration of benzodiazepines has shown superiority over rectal administration for terminating emergency epileptic seizures in human trials. No such clinical trials have been performed in dogs. OBJECTIVE To evaluate the clinical efficacy of intranasal midazolam (IN-MDZ), via a mucosal atomization device, as a first-line management option for canine status epilepticus...

Cropping systems models have evolved over the last four decades in response to the demand for modeling to address more complex questions, including issues on sustainable production, climate change, and environmental impacts. Early models, which were used primarily for yield gap analysis, have increased in complexity to include not only nutrient and water deficiencies, but also pest and disease ...

OBJECTIVE To assess the prevalence of headache in clinic and support group patients with celiac disease and inflammatory bowel disease (IBD) compared with a sample of healthy controls. BACKGROUND European studies have demonstrated increased prevalence of headache of patients with celiac disease compared with controls. METHODS Subjects took a self-administered survey containing clinical, dem...
