This paper demonstrates that piecewise, rotated explicit curves are flexible enough for 2–D modeling applications such as font design. Their use simplifies many operations such as scan conversion, point classification, and curve intersection.
We extend Approval voting to the settings where voters may have intransitive preferences. The major obstacle to applying Approval voting in these settings is that voters are not able to clearly determine who they should approve or disapprove, due to the intransitivity of their preferences. An approach to address this issue is to apply tournament solutions to help voters make the decision. We st...
Tumor maintenance relies on continued activity of driver oncogenes, although their rate-limiting role is highly context dependent. Oncogenic Kras mutation is the signature event in pancreatic ductal adenocarcinoma (PDAC), serving a critical role in tumor initiation. Here, an inducible Kras(G12D)-driven PDAC mouse model establishes that advanced PDAC remains strictly dependent on Kras(G12D) expr...
A total of 1,298 nonfermentative gram-negative rods were used to evaluate the performance of the individual biochemical tests in the N/F System and to determine whether the observed results included sufficient key reactions for rapid identification. The system included an oxidase test, two screening tubes providing 5 test reactions designed primarily to identify pigment-producing strains of Pse...
Nucleotide degradation is a universal metabolic capability. Here we combine metabolomics, genetics and biochemistry to characterize the yeast pathway. Nutrient starvation, via PKA, AMPK/SNF1, and TOR, triggers autophagic breakdown of ribosomes into nucleotides. A protein not previously associated with nucleotide degradation, Phm8, converts nucleotide monophosphates into nucleosides. Downstream ...
in a voice conversion system speech signal of a speaker (i.e. source speaker) is modified so that it sounds as if it had been pronounced by b speaker (i.e. target speaker). this process, sometimes, is called speaker conversion (changing speaker identity). achieved signal from speaker conversion system is desired to have high quality and very natural. to satisfy this, three major methods are pro...
objective: patients with conversion disorder may be seen by different specialists in various clinics and emergency situations. however, there are not sufficient studies on the most effective treatment for this disabling illness. methods: in a clinical trial, we compared four treatment strategies muscle relaxation, suggestion, hypnosis and intravenous diazepam infusion, in 80 patients with acute...
background: the aim of this study was to estimate the conversion rate from radiologically isolated syndrome (ris) to definite multiple sclerosis (ms). methods: during a mean (standard deviation [sd]) follow-up period of 17.4 (5.4) (range 8-29) months, 25 subjects with ris and without neurological symptom aged 22-45 year from a single-center have been examined for the occurrence of definite ms. ...
purpose: to report two cases of conversion disorder with unilateral psychogenic pseudoptosis. case reports: the first case was 21 years old man who developed sudden ptosis of his left eye, since 2 weeks ago. the patient had episodes of upper lid drooping during the last 7 months; the second case was a 10 years old girl with history of ptosis since 6 months, after viral conjunctivitis. all neuro...
cobalt chromite (cocr2o4) with normal spinel structure, shows catalytic activity for oxidation of unburned methane in the natural gas vehilcles (ngv). in this study, cocr2o4 nanoparticles were synthesized through a conventional co-precipitation technique and investigated for the catalytic combustion of methane. cobalt nitrate hexahydrate, chromium nitrate nonahydrate and ammonia solution (25%) ...
