The Army is developing hypergolic, liquid and gelled bipropellants for a small, selectable-thrust, liquid rocket engine (LRE) that can power tactical missiles for both current and future combat systems. The use of gel propellants brings the advantages of selectable thrust and the promise of small engine size but also introduces new challenges in combustion control. One of these challenges is th...
Natural compounds represent a rich and promising source of novel, biologically active chemical entities for treating leishmaniasis. Sesquiterpene lactones are a recognized class of terpenoids with a wide spectrum of biological activities, including activity against Leishmania spp. In this work, a sesquiterpene lactone-rich preparation-a leaf rinse extract (LRE) from Tithonia diversifolia-was te...
The Z-box is one of the light-responsive elements (LREs) found in the promoters of light inducible genes. We have studied the light responsive characteristics of Z-box containing synthetic as well as native promoters. We show that promoters with Z-box as a single LRE or paired with another LRE can respond to a broad spectrum of light. The response is primarily mediated by phyA, phyB and CRY1 ph...
Construction activities of accelerated urbanization in Shenzhen have increased the landslide risk area, which has intensified potential threat to human and natural environment. However, landslides is poorly evaluated. In this paper, a evaluation (LRE) model constructed using susceptibility map (LSM) vulnerability. experiment, stacking ensemble learning (SEL) based on convolutional neural networ...
The Multi-language Speech (MLS) Corpus supports NIST’s Language Recognition Evaluation series by providing new conversational telephone speech and broadcast narrowband data in 20 languages/dialects. The corpus was built with the intention of testing system performance in the matter of distinguishing closely related or confusable linguistic varieties, and careful manual auditing of collected dat...
In this paper we describe the new developments brought to LRE Map, especially in terms of the user interface of the Web application, of the searching of the information therein, and of the data model updates. Thus, users now have several new search facilities, such as faceted search and fuzzy textual search, they can now register, log in and store search bookmarks for further perusal. Moreover,...
The series of language recognition evaluations (LRE’s) conducted by the National Institute of Standards and Technology (NIST) have been one of the driving forces in advancing spoken language recognition technology. This paper presents a shared view of five institutions resulting from our collaboration toward LRE 2015 submissions under the names of I2R, Fantastic4, and SingaMS. Among others, LRE...
Once patients have a diagnosis of localization related epilepsy (LRE), it is critical to further classify those patients into lesional or nonlesional for treatment and prognostic reasons. An individual with LRE may be classified as nonlesional for two reasons: 1) a lesion may not exist; that is, the structural abnormality that gives rise to seizures may be at the channel level or be spatially d...
Phone log-likelihood ratio (PLLR) features have been shown to be effective in language identification systems. However, PLLR feature distributions are bounded and this may contradict assumptions of Gaussianity and consequently lead to reduced language recognition rates. In this paper, we propose a feature normalisation technique for the PLLR feature space and demonstrate that it can outperform ...
PURPOSE To compare subclinical balance dysfunction in patients with various epilepsy syndromes with apparently healthy subjects. METHODS Twenty-seven patients with localization-related epilepsy (LRE), 19 with primary generalized epilepsy (PGE), who had no subjective complaints of impaired balance and no abnormal neurologic findings on examination, and 22 apparently healthy subjects, underwent...
