BACKGROUND AND AIMS Root traits can be selected for crop improvement. Techniques such as soil excavations can be used to screen root traits in the field, but are limited to genotypes that are well-adapted to field conditions. The aim of this study was to compare a low-cost, high-throughput root phenotyping (HTP) technique in a controlled environment with field performance, using oilseed rape (O...
tion biology attracted a great deal of attention in past years (Curio 1996; Caro 1998; Sutherland 1998). While there has been wide recognition that behavior can profoundly influence the dynamics of populations (Sutherland 1996; Houston and McNamara 1997), empirical research linking behavior to demography is sparse (Anholt 1997; Levin et al. 2000). Furthermore, a framework for applying behaviora...
فضاهای باز نقش مهمی در کاهش وسعت، میزان عمل و نتایج اکثر حوادث طبیعی و مصنوعی دارند. از عمده ترین عملکردهای آن در هنگام بروز زلزله، جدا ساختن یک منطقه دارای پتانسیل خطر از دیگری و بدین ترتیب متمرکز کردن فعالیت نیروهای مخرب و جلوگیری از توسعه زنجیره ای وقایع می باشد. بررسیهای این پژوهش نشان میدهد که فضاهای باز شهری در محدوده شهر تبریز را می توان به چهار دسته اصلی فضاهای سبز عمومی شهری، اراضی ب...
In conventional recognition tasks, models are only trained to recognize learned targets, but it is usually difficult collect training examples of all potential categories. the testing phase, when receive test samples from unknown classes, they mistakenly classify into known classes. Open set (OSR) a more realistic task, which requires classifier detect while keeping high classification accuracy...
The worldwide increasing recourse to chemical dispersants to deal with oil spills in marine coastal ecosystems is a controversial issue. Yet, there exists no adequate methodology that can provide reliable predictions of how oil and dispersant-treated oil can affect relevant organism or population-level performance. The primary objective of the present study was to examine and compare the effect...
Markov Decision Processes (MDPs) are an effective model to represent decision processes in the presence of transitional uncertainty and reward tradeoffs. However, due to the difficulty in exactly specifying the transition and reward functions in MDPs, researchers have proposed uncertain MDP models and robustness objectives in solving those models. Most approaches for computing robust policies h...
PURPOSE We aimed to see the frequency of concomitant ischemic heart disease (IHD) in Korean patients with abdominal aortic aneurysm (AAA) and to determine risk factors for an early postoperative acute myocardial infarction (PAMI) after elective open or endovascular AAA repair. METHODS We retrospectively reviewed a database of patients who underwent elective AAA repair over the past 11 years. ...
PURPOSE The aim of this study was to investigate survival in patients aged ≥70 years who underwent colorectal cancer surgery in 2003 and 2009. In addition, we aimed to identify the factors that could affect survival in these patients. METHODS In a cross-sectional study, a retrospective review of the data for 878 patients who underwent colorectal cancer surgery with curative intent in the year...
Most of the biopharmaceuticals nowadays are produced by animal cells. The worldwide demand for a specific group of biopharmaceuticals, the monoclonal antibodies (mAbs), has significantly increased this last decade. The mAbs are used as therapeutics in particular against cancer and autoimmune disorders. Most of the mAbs are produced as recombinant proteins by mammalian cells which ensure human-l...
Cap1p, a transcription factor of the basic region leucine zipper family, regulates the oxidative stress response (OSR) in Candida albicans. Alteration of its C-terminal cysteine-rich domain (CRD) results in Cap1p nuclear retention and transcriptional activation. To better understand the function of Cap1p in C. albicans, we used genome-wide location profiling (chromatin immunoprecipitation-on-ch...
