A descr ip t ion is an enti ty tha t can be interpre ted as t rue or false of an object , and using fea ture s t ruc tures as descr ipt ions accrues several compu ta t i ona l benefits. In this paper , 1 create an explicit in te rpre ta t ion of a typed feature s t ruc ture used as a descript ion, define the not ion of a satisfiable fe.ature s t ructure , and create a s imple and effective a lg...

We have measured the hyperfine structure of mutually perturbing rovibrational levels of the 1sbd P0 and 2sAd S states of the NaK molecule, using the perturbation-facilitated optical-optical double resonance method with copropagating lasers. The unperturbed 1sbd P0 levels are split into four hyperfine components by the Fermi contact interaction bFI ·S. Mixing between the 1sbd P0 and 2sAd S level...

This paper presents a map-based system in which local residents can supply and share disaster prevention information. Producing a disaster prevention map with public participation is very useful as learning and awareness building for natural disasters. Our system's unique feature introduces a card-image data structure, which makes it easy for users to add new information, such as information ab...

with a matrix A ∈ R, m ≥ n, of ill-determined rank. In parti ular, A is severely illonditioned and possibly singular. Matri es of this kind arise, for instan e, from the dis retization of ill-posed problems, su h as Fredholm integral equations of the rst kind; see, e.g., [10, 16℄ for dis ussions. The ve tor b ∈ R represents observations and is assumed to be ontaminated by an error e ∈ R, whi h ...

Six water emergencies have occurred since 1981 for the NewYork City (NYC) region despite the following: 1) its perhumid climate, 2) substantial conservation of water since 1979, and 3) meteorological data showing little severe or extreme drought since 1970. This study reconstructs 472 years of moisture availability for the NYC watershed to place these emergencies in long-term hydroclimatic cont...

CITYCLUSTER is a Virtual-reality high networking matrix with original technological features, navigation, interactivity and graphic style. The framework, was developed according to a creative method of tracing diverse concepts and systems of collection of cities, urban ambiences and virtual spaces interconnected by a high-speed network which enables participants in remote locations to interact ...

Maser is an acronym for microwave amplification by stimulated emission of radiation; in astronomy mega-masers are masers in galaxies that are ≥ 10(6) times more luminous than typical galactic maser sources. Observational studies of mega-masers can help us to understand their origins and characteristics. More importantly, mega-masers can be used as diagnostic tracers to probe the physical proper...

We designed a protein ladder (hereafter referred to as "Mega-tag") that contains 14 of the most commonly used epitope tags fused to molecular weight markers. The Mega-tag ladder can be simultaneously visualized when anti-tag antibodies are used to detect epitope-tagged recombinant proteins in Western blots. The logarithm of molecular weights and relative mobility of the Mega-tag protein ladder ...
