In most eukaryotes, the histone methyltransferase SU(VAR)3-9 and its orthologues play amajor role in the function of centromeric heterochromatin. Although the methyltransferase domain isrequired for the formation of a fully functional centromere, mutations within other regions of the genesuch as the N-terminus also have a strong impact on its in vivo function. To analyze the contrib...

We propose a theory of how the speech gesture determines change in a functionally relevant variable of vocal tract state (e.g., constriction degree). A core postulate of the theory is that the gesture determines how the variable evolves in time independent of any executive timekeeper. That is, the theory involves intrinsic timing of speech gestures. We compare the theory against others in which...

We report the observation of surface-acoustic-wave Brillouin scattering (SAWBS) in a subwavelength-diameter fiber and show that this effect relies on the generation by the electrostrictive force of phonons confined at the surface of the microwire. OCIS codes: 290.5900, 060.4370, 160.6030 Brillouin scattering between sound and light waves has been extensively investigated in optical fibers. It i...

Aims, Objectives and Background There is evidence that COVID-19 ‘lockdowns’ may have contributed to increased non-accidental injury, domestic violence self-harm related deteriorating mental health. Internationally, there also the diversion of health care resources led worse outcomes for patients presenting with major trauma. has been no previous national evaluation ‘lockdown’ measures impact on...

The present paper is a humble attempt to test the allocative efficiency of the farmers in a traditional Orissan agriculture system in terms of resource-use and crop selection. While examining their allocative efficiency it is noted that the rational farmers are not necessarily efficient farmers. The farmers in the sample area are found to be rational in taking production decisions and efficient...

A series of homoleptic rare-earth silazido compounds and their silica-grafted derivatives were prepared to compare spectroscopic and catalytic features under homogeneous and interfacial conditions. Trivalent tris(silazido) compounds Ln{N(SiHMe2)tBu}3 (Ln = Sc (1), Y (2), Lu (3)) are prepared in high yield by salt metathesis reactions. Solution-phase and solid-state characterization of 1− 3 by N...
