Adapting the competitions method of Freivalds to the setting of unbounded-error prob-abilistic computation, we prove that, for any 2 (0; 1], Band-Mat-Inv(n) is log-space complete for the class of languages recognized by log-space unbounded-error probabilistic Turing machines (PL). This extends the result of Jung that Band-Mat-Inv(n) is log-space complete for PL, and may open new possibilities f...

زمینه و هدف : بیماری لپتوسپیروز یکی از شایع ترین بیماری های مشترک بین انسان و حیوان در سراسر دنیا محسوب می شود. بیماری گاهاً مهلک بوده و از طریق تماس مستقیم یا غیرمستقیم با ادرار حیوانات آلوده به لپتوسپیرا بروزمی کند. این مطالعه به منظور معرفی موارد بروز لپتوسپیروز در استان گلستان طی سال 1383 انجام شد. روش بررسی : طبق هماهنگیهای مقرر با مرکز بهداشت استان، 20 بیماری که با تشخیص پزشک معالج و بر ا...
تعیین تنوع ژنتیکی قارچ جدا شده از روی علفهای هرز به کمک واکنش pcr که در دانستن نوترکیبی های ژنتیکی احتمالی در جمعیت های قارچ بسیار مفید خواهد بود، برای اولین بار در ایران انجام شد. جدایه های قارچ magnaporthe grisea جدا شده از روی برخی علف های هرزگرامینه و برنج جهت تعیین تیپ آمیزشی به کمک واکنش pcr و تنوع ژنتیکی به کمک نشانگر rapd-pcr مورد تجزیه و تحلیل قرار گرفت. با استفاده از سه آغازگر تصادفی ...
background: toxoplasma gondii is a zoonotic protozoan parasite found worldwide and responsible for major economic losses in most classes of livestock. this study was aimed to determine the prevalence of t. gondii infection in sheep, cattle and horses in urmia, north-west of iran, using mat. methods : blood samples of 276 livestock and 26 horses were collected from july 2009 till april 2010. t...
One hundred sixteen spring-calving Polled Hereford x Angus cows were milked using milking machines after receiving 20 IU of oxytocin. Sires of the cows had been divergently selected on yearling weight (YW) and total maternal (MAT) EPD to form four groups: high YW, high MAT EPD; high YW, low MAT EPD; low YW, high MAT EPD; and low YW, low MAT EPD. Average milk production after 12-h calf separatio...
Pattern mat hing is a well-appre iated feature of languages like ML or Haskell; it greatly simpli es the task of inspe ting values of stru tured data types and fa ilitates su in t fun tion de nitions that are easy to understand. In its basi form, pattern mat hing tries to identify a ertain stru ture of a value to be pro essed by a fun tion. This stru ture is spe i ed by a pattern, and if it an ...
Study Aims. Evaluate the quality and effectiveness of the medication-assisted therapy (MAT) pilot in Kazakhstan and review implementation context and related challenges. Methods. We performed a desk review of MAT policy and program documents and reviewed medical records at three MAT sites in Kazakhstan. MAT patients (n = 93) were interviewed to assess their perceptions of the program and its im...
Marrow adipose tissue (MAT) accumulates in diverse clinical conditions but remains poorly understood. Here we show region-specific variation in MAT adipocyte development, regulation, size, lipid composition, gene expression and genetic determinants. Early MAT formation in mice is conserved, whereas later development is strain dependent. Proximal, but not distal tibial, MAT is lost with 21-day c...
The Podospora anserina premature death syndrome was described as early growth arrest caused by a site-specific deletion of the mitochondrial genome (mtDNA) and occurring in strains displaying the genotype AS1-4 mat-. The AS1-4 mutation lies in a gene encoding a cytosolic ribosomal protein, while mat- is one of the two forms (mat- and mat+) of the mating-type locus. Here we show that, depending ...
