We demonstrate an early version of a semantic web tool, Global Health Explorer (GHX), that can be used to conduct public health surveillance using Twitter. Our infrastructure can use any controlled vocabulary to extract term uses in Twitter and supports hypothesis formation and exploration of data sets using visual analysis. The resulting data, gathered in RDF, makes it possible to analyze term...

The thermodynamic stabilities (∆G, free energy change) of proteins are being measured by traditional denaturation methods (∆GU, free energy of unfolding) and native hydrogen-deuterium (H/D) exchange method (∆GHX, free energy of exchange), in general. Estimation of an accurate ∆G for proteins at ambient conditions is indispensable to unambiguously address the folding events of the proteins, whic...

A ground source heat pump system is a high-performance technology used for maintaining stable underground temperature all year-round. However, the high costs installation, such as boring and drilling, drawback that prevents to be rapidly introduced into market. This study proposes modular exchanger (GHX) can compensate disadvantages (such high-boring/drilling costs) of conventional vertical GHX...

Residue-specific stabilities of proteins can be reliably determined by using NMR-monitored hydrogen/deuterium exchange (NMR-H/D) methods under native conditions. Notwithstanding the potential advantages of the NMR-H/D methods, they are time consuming, very expensive and technically challenging. In this review article, various computational tools and strategies reported to date in the literature...

Ground-source heat pump (GSHP) utilizes the immense renewable storage capacity of the ground as a heat source or sink to provide space heating, cooling, and domestic hot water. GSHP systems are generally comprised of water source heat pumps and ground heat exchangers (GHX). Vertical closed-loop GHX is used predominantly in commercial and institutional applications. Closed loop GHX consists of a...

The completeness of normal rational curves, considered as (q + 1)-arcs in PG(n, q), is investigated. Previous results of Storme and Thas are improved by using a result by Kovacs. This solves the problem completely for large prime numbers q and odd nonsquare prime powers q = p2h+l with p prime, p > po(h), h>\,1where po(h) is an odd prime number which depends on h.

This paper proposes a novel spiral-double ground heat exchanger (GHX) that decreases conventional construction costs, facilitates installation, promotes transfer, and reduces thermal resistance. In this study, new effective installation procedure was proposed. Three-dimensional, transient, conjugated finite volume simulations were conducted to compare the thermo-hydraulic performance of traditi...

The global energy sector is aiming to rapidly transform systems into those less dependent on fossil fuels reduce their harmful effects the climate. Although ground source heat pump (GSHP) are more efficient than conventional air-source (ASHP) systems, high initial investment cost, particularly for a vertical closed-loop type exchanger (GHX), makes it difficult incorporate them small buildings. ...

The required length of vertical ground heat exchangers (GHX) used in ground-coupled heat pump (GCHP) systems is determined so that the outlet temperature from the GHX remains within certain limits for the worst ground load conditions. These conditions may not necessarily occur after 10 or 20 years of operation, as is usually assumed, but often occur during the first year of operation. The prima...
