Large alphabets: Finite, infinite, and scaling models
(Institute of Electrical and Electronics Engineers (IEEE), 201203)How can we effectively model situations with large alphabets? On a pragmatic level, any engineered system, be it for inference, communication, or encryption, requires working with a finite number of symbols. Therefore, the ... 
Large amplitude oscillatory shear flow of gluten dough: A model powerlaw gel
(American Institute of Physics, 201103)In a previous paper [T. S. K. Ng and G. H. McKinley, J. Rheol.52(2), 417–449 (2008)], we demonstrated that gluten gels can best be understood as a polymericnetwork with a powerlaw frequency response that reflects the ... 
Large amplitude oscillatory shear of pseudoplastic and elastoviscoplastic materials
(Springer Berlin / Heidelberg, 200912)We explore the utility of straincontrolled large amplitude oscillatory shear (LAOS) deformation for identifying and characterizing apparent yield stress responses in elastoviscoplastic materials. Our approach emphasizes ... 
Large and persistent photoconductivity due to holehole correlation in CdS
(American Physical Society, 201808)Large and persistent photoconductivity (LPPC) in semiconductors is due to the trapping of photogenerated minority carriers at crystal defects. Theory has suggested that anion vacancies in IIVI semiconductors are responsible ... 
Large anharmonic effect and thermal expansion anisotropy of metal chalcogenides: The case of antimony sulfide
(American Physical Society, 201512)We derive a compact matrix expression for the linear thermal expansion coefficients (TECs) for a general orthorhombic system which relates elastic properties and integrated quantities based on deformation and mode dependent ... 
Large Area 1.2 kV GaN Vertical Power FinFETs with a Record Switching FigureofMerit
(Institute of Electrical and Electronics Engineers (IEEE), 201811)This letter presents the first experimental study on capacitances, charges, and powerswitching figure of merits (FOM) for a largearea vertical GaN power transistor. A 1.2kV, 5A GaN vertical power FinFET was demonstrated ... 
Large area 3D reconstructions from underwater optical surveys
(Institute of Electrical and Electronics Engineers, 200904)Robotic underwater vehicles are regularly performing vast optical surveys of the ocean floor. Scientists value these surveys since optical images offer high levels of detail and are easily interpreted by humans. Unfortunately, ... 
Large area selective emitters/absorbers based on 2D tantalum photonic crystals for hightemperature energy applications
(Society of PhotoOptical Instrumentation Engineers (SPIE), 201302)We report highly selective emitters based on highaspect ratio 2D photonic crystals (PhCs) fabricated on large area (2 inch diameter) polycrystalline tantalum substrates, suitable for hightemperature operation. As an ... 
Large conditional singlephoton crossphase modulation
(National Academy of Sciences (U.S.), 201608)Deterministic optical quantum logic requires a nonlinear quantum process that alters the phase of a quantum optical state by π through interaction with only one photon. Here, we demonstrate a large conditional crossphase ... 
Large eddy simulation of flow and scalar transport in a vegetated channel
(Springer Netherlands, 201612)Predicting flow and mass transport in vegetated regions has a broad range of applications in ecology and engineering practice. This paper presents large eddy simulation (LES) of turbulent flow and scalar transport within ... 
Large effectivestrain piezoelectric actuators using nested cellular architecture with exponential strain amplification mechanisms
(Institute of Electrical and Electronics Engineers, 201008)Design and analysis of piezoelectric actuators having over 20% effective strain using an exponential strain amplification mechanism are presented in this paper. Piezoelectric ceramic material, such as lead zirconate titanate ... 
Large gauge transformations in double field theory
(SpringerVerlag, 201302)Finite gauge transformations in double field theory can be defined by the exponential of generalized Lie derivatives. We interpret these transformations as ‘generalized coordinate transformations’ in the doubled space by ... 
Large inherent optical gain from the direct gap transition of Ge thin films
(American Institute of Physics (AIP), 201304)The recent demonstration of GeonSi diode lasers renews the interest in the unique carrier dynamics of Ge involving both direct (Γ) and indirect (L) valleys. Here, we report a large inherent direct gap optical gain ... 
Large intergenic noncoding RNARoR modulates reprogramming of human induced pluripotent stem cells
(Nature Publishing Group, 201011)The conversion of lineagecommitted cells to induced pluripotent stem cells (iPSCs) by reprogramming is accompanied by a global remodeling of the epigenome[superscript 1, 2, 3, 4, 5], resulting in altered patterns of gene ... 
A Large Intergenic Noncoding RNA Induced by p53 Mediates Global Gene Repression in the p53 Response
(Elsevier, 201008)Recently, more than 1000 large intergenic noncoding RNAs (lincRNAs) have been reported. These RNAs are evolutionarily conserved in mammalian genomes and thus presumably function in diverse biological processes. Here, we ... 
Large Intermediates in Hydrazine Decomposition: A Theoretical Study of the N₃H₅ and N₄H₆ Potential Energy Surfaces
(American Chemical Society (ACS), 201905)Large complex formation involved in the thermal decomposition of hydrazine (N₂H₄) is studied using transition state theorybased theoretical kinetics. A comprehensive analysis of the N₃H₅ and N₄H₆ potential energy surfaces ... 
Large magnetoresistance in the typeII Weyl semimetal semimetal WP[subscript 2]
(American Physical Society, 201709)We report a magnetotransport study on typeII Weyl semimetal WP[subscript 2] single crystals. Magnetoresistance exhibits a nonsaturating H[superscript n] field dependence (14 300% at 2 K and 9 T), whereas systematic violation ... 
Large N Duality, Lagrangian Cycles, and Algebraic Knots
(SpringerVerlag, 201210)We consider knot invariants in the context of large N transitions of topological strings. In particular we consider aspects of Lagrangian cycles associated to knots in the conifold geometry. We show how these can be ... 
Large nonGaussianities with intermediate shapes from quasisinglefield inflation
(American Physical Society, 201003)We study the slowroll inflation models, where the inflaton slowrolls along a trajectory whose orthogonal directions are lifted by potentials with masses of order the Hubble parameter. In these models large nonGaussianities ...
