The host defence response (HDR) to insults is similar regardless of the tissue involved and consists of an interactive network of simultaneously activated pathways that act in synergy to increase the host's chance of survival. Among this cascade of integrated pathways, three aspects of the HDR, inflammation, coagulation and tissue repair, are analysed separately to explain the histological and ...
With the development of modern image sensors enabling flexible image acquisition, single shot high dynamic range (HDR) imaging is becoming increasingly popular. In this work, we capture single shot HDR images using an imaging sensor with spatially varying gain/ISO. This allows all incoming photons to be used in the imaging. Previous methods on single shot HDR capture use spatially varying neutr...
Purpose To investigate the differences in prostate-specific antigen (PSA) bounce (PB) after high-dose-rate (HDR-BT) or low-dose-rate (LDR-BT) brachytherapy alone in prostate cancer patients. Materials and methods Ninety-four patients with localized prostate cancer (T1-T2cN0), age ranged 50-81 years, were treated with brachytherapy alone between 2008 and 2010. Patients were diagnosed with aden...
background: migraine is a chronic disease that affects nearly 6% of men and 18% of women worldwide. there are various drugs, which can successfully decrease migraine symptoms and frequency of migraine attacks, but these drugs usually are expensive. hence, this study aimed to assess the effects of pyridoxine supplementation on severity, frequency and duration of migraine attacks as well as head...
High-damping rubber (HDR) dampers have the advantages of convenience for various shapes pressure blocks, aesthetic installation, easy maintenance, temperature stability, etc.; thus, they present good application prospects in vibration reduction stay cables. Hence, a model taut cable equipped with two types HDR damper—i.e., damper and tuned mass–high-damping (TM-HDR-D)—is established herein. The...
BACKGROUND AND OBJECTIVE In the last decade, the number of publications that report on the use of external beam radiotherapy and high-dose-rate brachytherapy (HDR-BRT) in the treatment of recurrent head and neck cancer has increased, but no studies compare external beam radiotherapy and HDR-BRT. The aim of this study was to evaluate and to compare the efficacy and toxicity of the three-dimensio...
Asymptotics and Optimal Bandwidth Selection for Highest Density Region Estimation1 by R. J. Samworth
We study kernel estimation of highest-density regions (HDR). Our main contributions are two-fold. First, we derive a uniform-in-bandwidth asymptotic approximation to a risk that is appropriate for HDR estimation. This approximation is then used to derive a bandwidth selection rule for HDR estimation possessing attractive asymptotic properties. We also present the results of numerical studies th...
A concept of "Fractal Fracture Mechanics" for HDR .(Hot Dry Rock) geothermal reservoir design has been developed as an extension of conventional rock fracture mechanics. It is suggested that this concept is successfully applicable to characterize and model subsurface fracture network in HDR geothermal reservoir. Furthermore, this modeling procedure makes it possible to evaluate the thermal ener...
چکیده از زمان ورود دوربین به ایران در دوره محمدشاه و به خصوص در عصر ناصری، عکاسی به صورت فنی شاهانه در خدمت سلاطین قاجاری قرار گرفت تا این که در دوره مشروطه، صنعت عکاسی از انحصار دربار خارج گردید و به میان مردم رفت، البته شواهد متعدد حاکی از آن هستند که روند عمومی شدن عکاسی از دوره پیشامشروطه آغاز شده بود اما انقلاب مشروطه در این روند جهش بزرگی ایجاد نمود. به رغم عمومی شدن عکاسی، تا اوایل قرن چ...
High-dose-rate (HDR) brachytherapy has become a popular treatment modality for localized prostate cancer. Prostate HDR treatment involves placing 10 to 20 catheters (needles) into the prostate gland, and then delivering radiation dose to the cancerous regions through these catheters. These catheters are often inserted with transrectal ultrasound (TRUS) guidance and the HDR treatment plan is bas...
