The League of Arab States (also known as the Arab League) is well past its sixth decade of establishment. However, it has a long way to go to achieve the objectives enumerated in its charter. In a sense, there is much stronger propensity towards disintegration than integration in the League. This article seeks to study the reasons that account for the failure of such integration in the Arab Lea...

UNLABELLED A major challenge in mass spectrometry and other large-scale applications is how to handle, integrate, and model the data that is produced. Given the speed at which technology advances and the need to keep pace with biological experiments, we designed a computational platform, CoreFlow, which provides programmers with a framework to manage data in real-time. It allows users to upload...

The fragmentation pathways of protonated peptides are reviewed in the present paper paying special attention to classification of the known fragmentation channels into a simple hierarchy defined according to the chemistry involved. It is shown that the 'mobile proton' model of peptide fragmentation can be used to understand the MS/MS spectra of protonated peptides only in a qualitative manner r...

Methods of Borel integration to calculate the binding ground energies and mass of bb̄ quarkonia are presented. The methods take into account the leading infrared renormalon structure of the ”soft” binding energy E(s) and of the quark pole masses mq , and the property that the contributions of these singularities in M(s) = 2mq +E(s) cancel. The resummation formalisms are applied to quantities whi...

Finite energy QCD sum rules involving both inverse and positive moment integration kernels are employed to determine the bottom quark mass. The result obtained in the MS scheme at a reference scale of 10GeV is mb(10GeV) = 3623(9)MeV. This value translates into a scale invariant mass mb(mb) = 4171(9)MeV. This result has the lowest total uncertainty of any method, and is less sensitive to a numbe...

In this letter we demonstrate the genericity of suppressed gaugino masses Ma ∼ m3/2 ln(MPlanck/m3/2) in the IIB string landscape, by showing that this relation holds for D7-brane gauginos whenever the associated modulus is stabilised by nonperturbative effects. Although m3/2 and Ma take many different values across the landscape, the above small mass hierarchy is maintained. We show that it is ...

Liquid-filled hollow-core photonic crystal fibers (HC-PCFs) are perfect optofluidic channels, uniquely providing low-loss optical guidance in a liquid medium. As a result, the overlap of the dissolved specimen and the intense light field in the micronsized core is increased manyfold compared to conventional bioanalytical techniques, facilitating highly-efficient photoactivation processes. Here ...

We study the dispersion and dissipation of the numerical scheme obtained by taking a weighted averaging of the consistent (finite element) mass matrix and lumped (spectral element) mass matrix for the small wavenumber limit. We find and prove that for the optimum blending the resulting scheme (a) provides 2p+4 order accuracy for p-th order method (two orders more accurate compared with finite a...

Metabolomics comprises the methods and techniques that are used to measure the small molecule composition of biofluids and tissues, and is actually one of the most rapidly evolving research fields. The determination of the metabolomic profile - the metabolome - has multiple applications in many biological sciences, including the developing of new diagnostic tools in medicine. Recent technologic...

Photoinduced cross-linking (PIC) has become a powerful tool in chemical biology for the identification and mapping of stable or transient interactions between biomacromolecules and their (unknown) ligands. However, the value of PIC for in vitro and in vivo structural proteomics can be realized only if cross-linking reports accurately on biomacromolecule secondary, tertiary, and quaternary struc...
