The helicity amplitudes of the $N(1520)$ and $N(1535)$ resonances in $\gamma^*p\to N^*$ electromagnetic transition are studied constituent quark model using impulse approximation, with proton assumed to be three-quark configurations. comparison theoretical results experimental data on $A_{1/2}$, $A_{3/2}$, $S_{1/2}$ indicates that primarily composed $L=1$ states but may contain additional compo...

[1] Microwave humidity measurements from polar orbiting satellites are affected by diurnal sampling biases which are caused by changes in the local observation time of the satellites. The long-term data records available from these satellites thus have spurious trends, which must be corrected. Diurnal cycles of the microwave measurements have been constructed by combining data over the period 2...

The land surface skin temperature diurnal cycle (LSTD) is an important element of the climate system. This variable, however, cannot be directly obtained globally from polar orbiting satellites because such satellites only pass a given area twice per day and because their infrared channels cannot observe the surface when the sky is cloudy. To obtain the skin temperature diurnal cycle and fully ...

The strangeness magnetic moment of the proton is shown to be small in the chiral quark model. The dominant loop contribution is due to kaons. The K∗ loop contributions are proportional to the difference between the strange and light constituent quark masses or m−2 K∗ and therefore small. The loop fluctuations that involve radiative transitions between K∗ mesons and kaons are small, when the cut...

Tidal currents below the floating Ross Ice shelf are reconstructed by using a numerical tidal model. They are predominantly diurnal, achieve maximum strength in regions near where the ice shelf runs aground, and are significantly enhanced by topographic Rossby wave propagation along the ice front. A comparison with observations of the vertical motion of the ice shelf surface indicates that the ...

Epidermolysis bullosa is a group of mechano-bullous genetic disorders caused by mutations in the genes encoding structural proteins of the skin. Dystrophic epidermolysis bullosa is caused by mutations in the COL7A1 gene encoding collagen VII, the main constituent of anchoring fibrils. In this group, there are autosomal dominant and recessive inheritances. The pre-tibial form is characterized by...

This article proposes a new theory for predicting the crack bridging performance of random short fibers involved in cementitious composites. The current theoretical model for estimating crack bridging performance of Random Short Fiber Reinforced Cement Composites (RSFRCC) under tension is limited to specific constituent properties: friction dominant fiber-matrix interface and complete fiber pul...

The first three harmonics (diurnal/semi-diurnal/tri-diurnal) of high amplitude anisotropic wave trains of cosmic ray intensity over the period 1991-1994 have been investigated for Deep River neutron monitoring station. Our study reveals that the diurnal time of maximum i.e. phase remains in the corotational/18 Hr direction, whereas the time of maximum for semi-diurnal anisotropy has no definite...

The pressure-corrected hourly counting rate data of neutron monitor stations, situated in different latitudes, have been employed to study the variation of cosmic ray diurnal anisotropy for a long period of 44 years (1965-2008). Some of these neutron monitors are situated in low latitudes with high cutoff rigidity. Annual averages of the diurnal amplitudes and phases have been obtained for each...
