Analysis of hadronic invariant mass spectrum in inclusive charmless semileptonic B decays [PDF]

, 1998
We make an analysis of the hadronic invariant mass spectrum in inclusive charmless semileptonic B meson decays in a QCD-based approach. The decay width is studied as a function of the invariant mass cut.

Synthesis and investigation of mass spectra of some novel benzimidazole derivatives

Macedonian Journal of Chemistry and Chemical Engineering, 2008
2-Substituted benzimidazoles (3) and (4a-c) were prepared via condensation of ethyl 2-thionyl-pyruvate (1) and hydrazidoyl derivatives (2a-c) with o-phenylene diamine in acetic acid.

Covariance of the One-Dimensional Mass Power Spectrum [PDF]

, 2004
We analyse the covariance of the one-dimensional mass power spectrum along lines of sight. The covariance reveals the correlation between different modes of fluctuations in the cosmic density field and gives the sample variance error for measurements of ...

T-duality in M-theory and supermembranes [PDF]

, 1997
The (q_1,q_2) SL(2,Z) string bound states of type IIB superstring theory admit two inequivalent (T-dual) representations in eleven dimensions in terms of a fundamental 2-brane.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Ultra-High-Performance Liquid Chromatography–Electrospray Ionization–High-Resolution Mass Spectrometry for Distinguishing the Origin of Ellagic Acid Extracts: Pomegranate Peels or Gallnuts

Molecules
Ellagic acid, known for its various biological activities, is widely used. Ellagic acid from pomegranate peels is safe for consumption, while that from gallnuts is only suitable for external use. However, there is currently no effective method to confirm

Glueball mass spectrum from supergravity [PDF]

, 1998
We calculate the spectrum of glueball masses in non-supersymmetric Yang-Mills theory in three and four dimensions, based on a conjectured duality between supergravity and large N gauge theories.

Mass spectrum and thermodynamics of quasi-conformal gauge theories from gauge/gravity duality

, 2011
We use gauge/gravity duality to study simultaneously the mass spectrum and the thermodynamics of a generic quasi-conformal gauge theory, specified by its beta function.
