We introduce SRI’s new speech recognition engine, DynaSpeak, which is characterized by its scalability and flexibility, high recognition accuracy, memory and speed efficiency, adaptation capability, efficient grammar optimization, support for natural language parsing functionality, and operation based on integer arithmetic. These features are designed to address the needs of the fast-developing...

in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...

According to some treatises, arctic and alpine sub-biomes are ecologically similar, whereas others find them highly dissimilar. Most peculiarly, large areas of northern tundra highlands fall outside of the two recent subdivisions of the tundra biome. We seek an ecologically natural resolution to this long-standing and far-reaching problem. We studied broad-scale patterns in climate and vegetati...

A major problem in natural vision is how neurons in the early visual system encode the widely varying visual input with the limited dynamic range of their activity. Recent experiments suggest that retinal neurons adapt their response not only to the temporal mean but also to the temporal variance of the visual input. Inspired by these results, we propose a simple model in which temporal adaptat...

An isolated skull of a procolophonid is described from the Owl Rock Member of the Chinle Formation in the Abajo Mountains of southeast Utah. Although poorly preserved, this specimen exhibits features that demonstrate a phylogenetic relationship with leptopleuronine procolophonids. These include the dentition, the greatly expanded orbitotemporal opening, the prominent quadratojugal spikes, and t...

Economists increasingly face opportunities to collaborate with ecologists on landscape-level analyses of socioeconomic and ecological processes. Tnis often calls for developing empirical models to project land use change as input into ecological models. Providing ecologists with the land use information they desire can present many challenges regarding data, modeling, and econometrics. This pap...

Introduction: Equilibrated lithic clasts in unequilibrated chondrites probably represent thermal metamorphism in the early solar system before or during accretion of chondritic parent bodies. Lithic clasts with equilibrated features are rare in unequilibrated chondrites and their origins are not well-understood [1]. Recently, we observed an unusual lithic clast with thermal-metamorphosed featur...

Climate change is one of the crucial factors, which threaten many sector such as agriculture, water resource for decades, and the sector is more sensitive to climatic conditions.  Communities are the most vulnerable to the adverse impacts of climate change and variability because of their low adaptive capacity. One of the challenges of climate change and human spatial dimensions of climate...
