TL;DR: In this paper, a search for a dark boson Z′ coupling with the second and third generations of leptons in the reaction e+e− → μ+μ− Z′,Z′ → μ +μ− using 514 fb^(−1) of data collected by the BABAR experiment is reported, but no significant signal is observed for Z′ masses in the range 0.212-10 GeV.
Abstract: Many models of physics beyond the standard model predict the existence of new Abelian forces with new gauge bosons mediating interactions between “dark sectors” and the standard model. We report a search for a dark boson Z′ coupling only to the second and third generations of leptons in the reaction e+e− → μ+μ− Z′,Z′ → μ+μ− using 514 fb^(−1) of data collected by the BABAR experiment. No significant signal is observed for Z′ masses in the range 0.212–10 GeV. Limits on the coupling parameter g′ as low as 7×10^(−4) are derived, leading to improvements in the bounds compared to those previously derived from neutrino experiments.

TL;DR: The performance of the combined method for VOP detection is improved by 2.13% compared to the best performing individual Vop detection method.
Abstract: Vowel onset point (VOP) is the instant at which the onset of vowel takes place during speech production. There are significant changes occurring in the energies of excitation source, spectral peaks, and modulation spectrum at the VOP. This paper demonstrates the independent use of each of these three energies in detecting the VOPs. Since each of these energies represents a different aspect of speech production, it may be possible that they contain complementary information about the VOP. The individual evidences are therefore combined for detecting the VOPs. The error rates measured as the ratio of missing and spurious to the total number of VOPs evaluated on the sentences taken from the TIMIT database are 6.92%, 8.8%, 6.13%, and 4.0% for source, spectral peaks, modulation spectrum, and combined information, respectively. The performance of the combined method for VOP detection is improved by 2.13% compared to the best performing individual VOP detection method.

TL;DR: A 14 February 2002 report and order by the federal communications commission authorizes the unlicensed use of UWB in 3.1--10.6 GHz to provide an efficient use of scarce radio bandwidth while enabling both high data rate personal area network (PAN) wireless connectivity and longer-range, low data rate applications as well as radar and imaging systems.
Abstract: Ultra-wideband (UWB) wireless communication is a revolutionary technology for transmitting large amounts of digital data over a wide frequency spectrum using short-pulse, low powered radio signals. UWB commonly refers to a signal or system that either has a large relative bandwidth (BW) that exceeds 20% or a large absolute bandwidth of more than 500 MHz. A 14 February 2002 report and order by the federal communications commission (FCC) authorizes the unlicensed use of UWB in 3.1--10.6 GHz. This is intended to provide an efficient use of scarce radio bandwidth while enabling both high data rate personal area network (PAN) wireless connectivity and longer-range, low data rate applications as well as radar and imaging systems.

TL;DR: In this paper, the effects of binding and conformational changes induced by the neutral amphiphilic ligand [5-(alkoxy)naphthalen-1-amine] with different alkyl chain lengths on bovine serum albumin (BSA) have been studied using UV−visible and fluorescence spectroscopic methods.
Abstract: The effects of binding and conformational changes induced by the neutral amphiphilic ligand [5-(alkoxy)naphthalen-1-amine] with different alkyl chain lengths on bovine serum albumin (BSA) have been studied using UV−visible and fluorescence spectroscopic methods. The BSA fluorescence exhibits appreciable bathochromic shift along with a reduction in fluorescence intensity and fluorescence lifetime upon binding with ligands. Ligand quenches the fluorescence of BSA in a concentration-dependent manner and deviates positively from the linear Stern−Volmer equation. The calculated quenching rate constants and binding constants were shown to depend entirely on the alkyl chain length of the ligands. After binding of probes with protein, the distance between the donor and acceptor was calculated using Forster theory. Ligands bind near Trp-134 in the subdomain IA of the native BSA and they become accessible to Trp-212 when BSA gets unfolded. The spectral data well supports the idea that BSA changes its three-dimensio...
