Driven quantum materials often feature emergent topology, otherwise absent in static crystals. Dynamic bulk-boundary correspondence, encoded by nondissipative gapless modes residing near the Floquet zone center and/or boundaries, is its most prominent example. Here we show that topologically robust gapless dispersive modes appear along the grain boundaries, embedded in the interior of Floquet topological crystals, when the Floquet-Bloch band inversion occurring at a finite momentum ( ) and the Burgers vector ( ) of the constituting array of dislocations satisfy (modulo ).

Steaks were aged for 14 d, and tenderness was determined by slice shear force (SSF). Metabolomic profiling of beef samples was performed using rapid evaporative ionization mass spectrometry (REIMS) (N = 2853).

Grapevine red blotch virus (GRBV, species , genus , family ), the causal agent of red blotch disease, is transmitted by (Hemiptera: Membracidae) in a circulative, non-propagative mode. To gain new insight into GRBV- interactions, we delved into vertical transmission and documented a lack of transovarial transmission.

This study was aimed to determine the seroprevalence of bovine anaplasmosis on randomly selected 61 commercial dairy farms in 3 intensive regions of Bangladesh. A total of 1472 sera were analysed using VMRD Antibody Test Kit cELISA v2 for the presence of -specific antibodies.
View Article and Find Full Text PDFThiyl radicals are important reactive sulfur species and can cause cis to trans isomerization on unsaturated fatty acids. However, biocompatible strategies for the controlled generation of thiyl radicals are still lacking. In this work, we report the study of a series of naphthacyl-derived thioethers as photo-triggered thiyl radical precursors.
