هرچند که فیلتر ذره ای (particle filter) ابزاری موثر در ردیابی شیء می باشد، اما یکی از محدودیت های موجود، نیاز به وجود مدلی دقیق برای حالت سیستم و مشاهدات است. بنابراین یکی از زمینه های مورد علاقه محققین تخمین تابع مشاهده با توجه به داده های یادگیری است. تابع مشاهده ممکن است خطی یا غیرخطی در نظر گرفته شود. روش های موجود در تخمین تابع مشاهده با مشکلاتی مواجه هستند. از جمله این مشکلات، وابستگی به ...
OBJECTIVES: The aim of this observational descriptive study of morphological research is to assess the nervous structures within the embryonic and early fetal brains not previously documented in literature by HDlive and Silhouette® modes. STUDY DESIGN: A total of 26 subjects were examined in vivo, i.e. 15 embryos and 11 fetuses in the first trimester of pregnancy (7 to 13 gestational weeks (GW)...
BACKGROUND This study focuses on long-term mortality, specifically brain cancer, amyotrophic lateral sclerosis (ALS), Parkinson's disease, and multiple sclerosis (MS) of 621,902 veterans who served in the 1990-1991 Persian Gulf War (GW), and 746,248 non-GW veterans. METHODS Follow-up began with the date the veteran left the GW theater or May 1, 1991 and ended with the date of death or Decembe...
انسان موجودی است که از دیرباز توجه اندیشمندان را به خویش معطوف ساخته و از جهات گوناگون مورد بررسی و تحلیل قرارگرفته است. عرفا و فلاسفه نیز، هر کدام به این موضوع پرداختهاند، لیکن دستیابی به تعریفی که تفاوتهای لفظی و ظاهری آنان را در این حوزه خاتمه بخشد بس دشوار است. باوجود این، پرداختن به این مسأله برای تقریب دیدگاه اندیشمندانی که دراینباره اندیشیدهاند، لازم و ضروری به نظر میآید....
Power density producing damage at a probability of 0.5 (ie, damage threshold, DT-50) was determined for PMMA (with/without UV absorber) and Silicone intraocular lenses. Scattered light from a collinear diagnostic He:Ne beam was one of four damage monitors deployed to enhance the sensitivity of the system. In order of increasing laser resistance the following results were obtained: injection mol...
Risk of cancer in patients with genital warts: A nationwide, population-based cohort study in Taiwan
BACKGROUND Condyloma acuminata currently affects around 1% of sexually active adults, and its incidence is increasing. The coexistence of genital warts (GW) and certain cancers and an association between human papillomavirus (HPV) and various malignancies have been reported. Therefore, we conducted this large national study to analyze the risk of malignancies among men and women with GW in Taiw...
BACKGROUND The angiographic no-reflow phenomenon is an adverse prognostic factor in patients with acute myocardial infarction (AMI). The aim of the present study was to evaluate the effects of an occlusive balloon type distal protection device (PercuSurge GuardWire: GW) during primary stenting in patients with anterior AMI. METHODS AND RESULTS The GW group included 42 patients treated by prim...
GW bodies (or P-bodies) are cytoplasmic granules containing proteins involved in both mRNA degradation and storage, including the RNA interference machinery. Their mechanism of assembly and function are still poorly known although their number depends upon the flux of mRNA to be stored or degraded. We show here that silencing of the translational regulator CPEB1 leads to their disappearance, as...
It has been reported that treatment of cultured human skeletal muscle myotubes with the peroxisome proliferator-activated receptor-delta (PPARdelta) activator GW-501516 directly stimulates glucose transport and enhances insulin action. Cultured myotubes are minimally responsive to insulin stimulation of glucose transport and are not a good model for studying skeletal muscle glucose transport. T...
LetGw be a weighted graph. The number of the positive, negative and zero eigenvalues in the spectrum of Gw are called positive inertia index, negative inertia index and nullity of Gw, and denoted by i+(Gw), i−(Gw), i0(Gw), respectively. In this paper, sharp lower bound on the positive (resp. negative) inertia index of weighted bicyclic graphs of order n with pendant vertices is obtained. Moreov...
