K-point longitudinal acoustic phonons are responsible for ultrafast intervalley scattering in monolayer MoSe2
(2022)In transition metal dichalcogenides, valley depolarization through intervalley carrier scattering by zone-edge phonons is often unavoidable. Although valley depolarization processes related to various acoustic phonons have been suggested, their optical verification is still vague due to nearly degenerate phonon frequencies on acoustic phonon branches ... -
K2ﾠReveals Pulsed Accretion Driven by the 2 Myr Old Hot Jupiter CI Tau b
(2018)CIﾠTau is a young (~2 Myr) classical T Tauri star located in the Taurus star-forming region. Radial velocity observations indicate it hosts a Jupiter-sized planet with an orbital period of approximately 9 days. In this work, we analyze time series of CIﾠTau's photometric variability as seen byﾠK2. The light curve reveals the stellar rotation period ... -
Kagome fiber based ultrafast laser microsurgery probe delivering micro-Joule pulse energies
(2016)We present the development of a 5 mm, piezo-actuated, ultrafast laser scalpel for fast tissue microsurgery. Delivery of micro-Joules level energies to the tissue was made possible by a large, 31 μm, air-cored inhibited-coupling Kagome fiber. We overcome the fiber’s low NA by using lenses made of high refractive index ZnS, which produced an optimal ... -
Karmarkar as a Classical Method
(1987-03)In this work we demonstrate that the Karmarkar algorithm for linear programs results from the classical approach of first transforming nonnegativity constraints into equality constraints by adding squared-slack variables and then applying the method of successive linear programming (SLP) to the resulting nonlinear program. Three specific formulations ... -
KAS-III free FA synthesis
(2020-12-01)The present disclosure describes a genetically engineered a KASIII-independent fatty acid biosynthetic pathway that makes use of the promiscuous nature of the rest of the FAS enzymes (3-ketoacyl-ACP synthetase, 3-ketoacyl-ACP reductase, 3-hydroxyacyl ACP dehydrase, enoyl-ACP reductase) to bypass the KASIII step by providing a Co-A precursor of two ... -
KAT2A coupled with the α-KGDH complex acts as a histone H3 succinyltransferase
(2017)Histone modifications, such as the frequently occurring lysine succinylation1,2, are central to the regulation of chromatin-based processes. However, the mechanism and functional consequences of histone succinylation are unknown. Here we show that the α-ketoglutarate dehydrogenase (α-KGDH) complex is localized in the nucleus in human cell lines and ... -
Keeping the Analog Genie in the Bottle: A Case for Digital Robots
(1999-05-01)In this paper, we consider the case for adopting a truly 'digital' type of robot, which would evolve between a discrete and finite set of states. We adopt the point of view that the advantages of traditional robotic evolution (over the full range of a continuous domain) are often negated by complexities associated with the continuous world. The types ... -
Keeping the rhythm: light/dark cycles during postharvest storage preserve the tissue integrity and nutritional content of leafy plants
(2015)Background: The modular body structure of plants enables detached plant organs, such as postharvest fruits and vegetables, to maintain active responsiveness to environmental stimuli, including daily cycles of light and darkness. Twenty-four hour light/darkness cycles entrain plant circadian clock rhythms, which provide advantage to plants. Here, we ... -
