We demonstrate a ring-shaped Bessel-like photonic lattice akin to a photonic bandgap fiber with a low-index core. While the ring lattice is optically induced in a bulk crystal with a self-defocusing nonlinearity, guidance of a probe beam propagating linearly through the core is clearly observed. The possible mechanism for such guidance is also discussed.
Cryo-electron microscopy in conjunction with advanced image analysis was used to analyze the structure of the 26S proteasome and to elucidate its variable features. We have been able to outline the boundaries of the ATPase module in the "base" part of the regulatory complex that can vary in its position and orientation relative to the 20S core particle. This variation is consistent with the "wo...
The best constraints on the internal structures of giant planets have historically originated from measurements their gravity fields1–3. These data are inherently mostly sensitive to a planet’s outer regions, stymieing efforts measure mass and compactness cores Jupiter2,4,5 Saturn6,7. However, studies Saturn’s rings detected waves driven by pulsation modes within planet8–11, offering independen...
We study electric–magnetic duality in the chiral ring of a supersymmetric U(Nc) gauge theory with adjoint and fundamental matter, in presence of a general confining phase superpotential for the adjoint and the mesons. We find the magnetic solution corresponding to both the pseudoconfining and higgs electric vacua. By means of the Dijkgraaf–Vafa method, we match the effective glueball superpoten...
Maoecrystal V is a highly oxidized and rearranged norterpenoid isolated from the Chinese herb, Isodon eriocalyx. A synthetic route for C/D/E-ring core compound of maoecrystal has been developed. Introduction C1 fragment to D/E-ring was achieved by lithito dithiane attack, C-ring formed deprotective intramolecular hemiacetalization dithiane-alcohol precursor.
Podosomes are multimolecular mechanosensory assemblies that coordinate mesenchymal migration of tissue-resident dendritic cells. They have a protrusive actin core and an adhesive ring of integrins and adaptor proteins, such as talin and vinculin. We recently demonstrated that core actin oscillations correlate with intensity fluctuations of vinculin but not talin, suggesting different molecular ...
