Performance analysis of M-QAM scheme combined with multiuser diversity over Nakagami-m fading channels
No full textIn this paper, we consider an M-ary quadrature amplitude modulation (M-QAM) scheme combined with multiuser diversity over Nakagami-m fading channels. Assuming that delayed but error-free signal-to-noise ratio (SNR) feedback is available, we derive closed-form formulas for the average transmission rate and the average bit error rate (BER), which are also shown to be generalizations of many previous results. Through numerical studies and simulations, we check the validity of our analysis. In addition, we investigate the impact of the Nakagami fading parameter m and feedback delay on system performance.This research was supported by the MIC (Ministry of Information and Communication), Korea, under the ITRC (Information Technology Research Center) support program supervised by the IITA (Institute of Information Technology Assessment).

Transport of organic carbon from the California coast to the slope region : a study of Δ14C and δ13C signatures of organic compound classes

The definitive version was published in Global Biogeochemical Cycles 19 (2005): GB2018, doi:10.1029/2004GB002422.Surface sediments along a transect from an abyssal site in the northeastern Pacific (Station M, 34°50′N, 123°00′W) to a small mountainous river on the California coast (Santa Clara River) were studied to investigate the sources and cycling of organic matter on the continental margin. Sediment samples were separated into organic compound fractions (extractable lipids, amino acids (THAA), carbohydrates (TCHO), and the acid-insoluble fraction), and their carbon isotope ratios were measured. The Δ14C values of all the THAA and TCHO fractions were greater than −100‰, indicating relatively modern organic carbon (OC) source(s), and rapid cycling of these fractions. In contrast, the Δ14C values of extractable lipids and the acid-insoluble fraction were distinctly lower than those of the THAA and TCHO fractions. The Δ14C values of source OC to the sediments were estimated using a simple mixed layer model. These values were lower than the Δ14C signatures of pre-industrial plankton suggesting input of both old OC and contemporary plankton to the margin sediments. The source of old OC at the 2000-m site was likely from laterally transported coastal sediment. The estimated low Δ14C value of the transported OC suggests that old lipids and acid-insoluble material were selectively transported to the 2000-m site. The contribution of riverine POC to the margin sediments were estimated from Δ14C and δ13C values and indicate that relict OC exported by rivers was an important source of old lipids and acid-insoluble material to sedimentary OC on the shelf.This research was

Bistable stochastic biochemical networks: large chemical networks and systems with many molecules
No full textIn this paper we continue the program started in Hwang and Velazquez (J Math Chem, to appear). We describe some chemical systems exhibiting bistable behavior with reaction constants of order one, but where bistability is due to the presence of a large number of chemical species or a large number of molecules of some of the species. We derive generalizations of the classical Kramers' formula that gives the switching times for some particular systems exhibiting a large number of species.X1124sciescopu

Hunyadi, A., Murányi, D. and Páll-Gergely, B., 08 August 2016. Remarks In the original description, Hwang (2014) mentioned three differences between Indian B. plicidens and the subspecies Bensonella plicidens lakainguta. The most important of them was the submarginal elevations of columellar, basal and palatal barriers, i.e. anterior to the hooks those barriers become more elevated. However, this trait can also be seen in Indian B. hooki sp. nov. (Figure 9 (c,d)); see differences between B. lakainguta and B. hooki sp. nov. outlined under the description of the latter. Boysidia (Bensonella) qingliangfengensis (Figure 7 (e,f)) was described from the border region of the Chinese Anhui and Zhejiang Provinces (very close to Pilsbry̾s (1917) record from Hangzhou), and is claimed to be larger than B . plicidens, yet looks identical for all other characters. Therefore, it is treated here as a junior synonym of B . lakainguta Hwang, 2014. Maassen (1999) mentioned that he compared Bensonella karoensis with Japanese shells of Bensonella plicidens (= Bensonella lakainguta). Furthermore, he erroneously stated that Bensonella plicidens inhabited Thailand.Published as part of Páll-Gergely, Barna & White, Tom S., 2023, Solving the mystery of the misunderstood Bensonella plicidens (Benson, 1849) (Gastropoda: Stylommatophora: Hypselostomatidae), pp. 2011-2029 in Journal of Natural History 56 (45 - 48) on pages 2025-2026, DOI: 10.1080/00222933.2022.2152750, http://zenodo.org/record/756093
