The high energy thermodynamics of Little String Theory (LST) is known to be unstable. An unresolved question is whether the corresponding instability in LST holographic dual is of stringy or supergravity origin. We study UV thermodynamics of a large metric deformation of the LST dual realized (in the extremal case) by type IIB fivebranes wrapping a two-sphere of a resolved conifold, and demonst...

Since 2005, the Land Surface Analysis Satellite Application Facility (LSA SAF) operationally retrieves Land Surface Temperature (LST) for the Spinning Enhanced Visible and Infrared Imager (SEVIRI) on board Meteosat Second Generation (MSG). The high temporal resolution of the Meteosat satellites and their long term availability since 1977 make their data highly valuable for climate studies. In o...

In 1978, Lientz, Swanson, and Tompkins published the results of a survey on software maintenance. They found that 17.4% of maintenance effort was categorized as corrective in nature, 18.2% as adaptive, 60.3% as perfective, and 4.1% was categorized as other. We refer to this result as “LST.” We contrast this survey-based result with our empirical results from the analysis of data for the repeate...

BACKGROUND Lateral dural venous sinus thrombosis (LST) represents a serious complication of acute or chronic otitis media. It is thought to develop from the progression of inflammation and granulation tissue formation in the perisinus bone to infection of the sinus wall proper, with incitement of mural thrombosis. Treatment of LST typically includes the administration of broad-spectrum parenter...

BACKGROUND AND AIMS Laterally spreading tumor (LST) is a colorectal pre-cancerous lesion. Previous studies have demonstrated distinct LST clinicopathological characteristics in different populations. This study evaluated clinicopathological characteristics of LST in a Chinese population. METHODS A total of 259 Chinese LST patients with 289 lesions were recruited for endoscopic and clinicopath...

برآورد رطوبت خاک سطحی برای مدیریت بهینه منابع آب و خاک ضروری است. رطوبت خاک سطحی، متغیری مهم در چرخۀ آبی طبیعت است که نقش مهمی در تعادل جهانی آب و انرژی به واسطه تاثیر بر فرآینده­های هیدرولوژیک، اکولوژیک و هواشناسی دارد. رطوبت خاک به دلیل تغییر­پذیری ویژگی­های خاک، توپوگرافی، پوشش گیاهی و پویایی نیوار در زمان و مکان تغییر می­کند. اندازه­گیری رطوبت خاک، به طور مستقیم با استفاده از روش­های درجا م...

Land Surface Temperature (LST) is one of the most important physical and climatological  crucial yet variable parameter in environmental phenomena studies such as, soil moisture conditions, urban heat island, vegetation health, fire risk for forest areas and heats effects on human’s health. These studies need to land surface temperature with high spatial and temporal resolution. Remote sensing ...

Several indices, including the normalized difference vegetation index (NDVI), normalized difference build-up index (NDBI), and normalized difference water index (NDWI), were retrieved from the Landsat 5 Thematic Mapper (TM) images, and the land surface temperature (LST) was reversed by the thermal radiation transfer model. Next, with the help of the thermal field variance index from LST, charac...

Haemophilus ducreyi, the cause of the sexually transmitted disease chancroid produces a lipooligosaccharide (LOS) containing a terminal sialyl N-acetyllactosamine trisaccharide. Previously, we reported the identification and characterization of the N-acetylneuraminic acid cytidylsynthetase gene (neuA). Forty-nine base pairs downstream of the synthetase gene is an open reading frame (ORF) encodi...

Information on land surface temperature (LST) is important for understanding climate change, modeling the hydrological and biogeochemical cycles, and is a prime candidate parameter for Numerical Weather Prediction assimilation models. In particular, the LST data derived from geostationary operational environmental satellite (GOES) provides unique opportunity for studying LST diurnal variation. ...
