رطوبت خاک به عنوان یک متغیر کلیدی در سیستمهای زمینی عاملی تعیینکننده در تبادلات آب و انرژی بین سطح زمین و اتمسفر است. در این تحقیق اعتبارسنجی دادههای رطوبت خاک ماهواره SMAP در زمانها و کاربریهای مختلف با چهار شاخص ضریب همبستگی، ریشه میانگین مربعات خطا، ریشه میانگین مربعات خطا نااریب و میانگین اختلاف در سال 2017 بررسی شد. به این منظور، حوضه سیمینه-زرینه به عنوان بزرگترین زیر حوضه آبریز دریا...
There is a strong demand for soil moisture information in establishing efficient irrigation scheduling, climate change prediction, and sustainable land and water management. However, such data are not readily available with an appropriate accuracy or spatial and temporal resolution. Addressing the need for soil moisture at high resolution globally, the European Space Agency (ESA) has developed ...
Passive microwave remote sensing at L-band (1.4 GHz) provides an unprecedented opportunity to estimate global surface soil moisture (SM) and vegetation water content (via the optical depth, VOD), which are essential monitor Earth carbon cycles. Currently, only two space-borne radiometer missions operating: Soil Moisture Ocean Salinity (SMOS) Active (SMAP) in orbit since 2009 2015, respectively....
The in vitro activity of six cathelicidin peptides against 25 strains of Chlamydia was investigated. SMAP-29 proved to be the most active peptide, reducing the inclusion numbers of all 10 strains of Chlamydia trachomatis tested by > or =50% at 10 microg/ml. This peptide was also active against C. pneumoniae and C. felis.
BACKGROUND As a consequence of recent RNAseq efforts, miRNAomes of diverse tissues and species are available. However, most interactions between microRNAs and regulated mRNAs are still to be deciphered. While in silico analysis of microRNAs results in prediction of hundreds of potential targets, bona-fide interactions have to be verified e.g. by luciferase reporter assays using fused target sit...
Soil moisture is a crucial component of the water cycle and plays an important role in regional weather climate. However, owing to lack In Situ observations, accurate understanding spatiotemporal variations soil (SM) on Tibetan Plateau (TP) still lacking. this study, we used three gridded SM products characterize features TP during warm season (May August). We analyzed fifth-generation European...
The S-Map is a network with a simple learning algorithm that combines the self-organization capability of the Self-Organizing Map (SOM) and the probabilistic interpretability of the Generative Topographic Mapping (GTM). The simulations suggest that the SMap algorithm has a stronger tendency to self-organize from random initial configuration than the GTM. The S-Map algorithm can be further simpl...
This paper reports the outcomes of a longitudinal study on the CLEF Ad Hoc track in order to assess its impact in the last fifteen years on the effectiveness of monolingual, bilingual and multilingual information access and retrieval systems. 1 Motivations and Approach Experimental evaluation has been a key driver for research and innovation in the Information Retrieval (IR) field since its inc...
A multi-channel statistical classifier to detect prostate cancer was developed by combining information from 3 different MR methodologies: T2-weighted, T2-mapping, and Line Scan Diffusion lmaging(LSDI). From these MR sequences, 4 sets of image intensities were obtained: T2-weighted(T2W) from T2-weighted imaging, Apparent Diffusion Coefficient(ADC) from LSDI, and Proton Density (PD) and T2 (T2Ma...
