We study twist-three effects in deeply virtual Compton scattering on an unpolarized spin-1/2 target. A careful definition of observables as Fourier moments w.r.t. the azimuthal angle allows for a clear separation of twist-two and-three effects. Although the latter are power suppressed, they give leading contributions to the twist-three asymmetries and do not affect the twist-two observables.

Aberrant epidermal growth factor receptor (EGFR) signaling is a major cause of tumor progression and metastasis; the underlying mechanisms, however, are not well understood. In particular, it remains elusive whether deregulated EGFR pathway is involved in epithelial-mesenchymal transition (EMT), an early event that occurs during metastasis of cancers of an epithelial origin. Here, we show that ...

In recent years there has been growing interest in the polarized photon structure functions. Especially the first moment of a photon structure function g 1 has attracted much attention in connection with the axial anomaly which is also relevant in the nucleon spin structure function g p(n) 1 . The polarized structure function g γ 1 could be experimentally studied in the polarized version of ep ...

We present the first systematic study of higher-twist light-cone distribution amplitudes of the nucleon in QCD. We find that the valence three-quark state is described at small transverse separations by eight independent distribution amplitudes. One of them is leading twist-3, three distributions are twist-4 and twist-5, respectively, and one is twist-6. A complete set of distribution amplitude...

In the title compound, C19H24N2O2, a di-Mannich base derived from 2-methyl-phenol and 1,3,6,8-tetra-aza-tri-cyclo-[4.4.1.1(3,8)]dodecane, the imidazolidine ring adopts a twist conformation, with a twist about the ring N-C bond [C-N-C-C torsion angle = -44.34 (14)°]. The two 2-hy-droxy-3-methyl-benzyl groups are located in trans positions with respect to the imidazolidine fragment. The structure...

Cross section formulas for the Λ polarization in pp → Λ↑(`T )X and ep→ Λ↑(`T )X are derived and its characteristic features are discussed. In this report we discuss the polarization of Λ hyperon produced in unpolarized pp and ep collisions relevant for the ongoing RHIC-SPIN, HERMES and COMPASS experiments. According to the QCD factorization theorem, the polarized cross section for pp→ Λ↑X consi...

in the present work an attempt has been made to study the effect of the twisted tapes as bed internals, on the performance of the gas-solid fluidized beds. experimental investigation has been carried out in cylindrical column with and without twisted tapes. twelve numbers of twisted tapes of three different widths with four values of the twist ratios for each width were studied at different sta...

Basic helix-loop-helix (bHLH) transcription factors play critical roles in lymphoid and erythroid development; however, little is known about their role in myeloid lineage development. In this study, we identify the bHLH transcription factor Twist-2 as a key negative regulator of myeloid lineage development, as manifested by marked increases in mature myeloid populations of macrophages, neutrop...

PURPOSE To evaluate the load to failure and the mode of failure of a novel suture anchor construct that does not require knots (the "twist-lock" construct) and to compare it with a standard suture anchor construct (Corkscrew; Arthrex, Naples, FL). TYPE OF STUDY Biomechanical single-pull load-to-failure study comparing the twist-lock construct to the Corkscrew suture anchor construct. METHOD...
