Efficiency of energy funneling in the photosystem II supercomplex of higher plants
(Royal Society of Chemistry (RSC), 2016)The investigation of energy transfer properties in photosynthetic multi-protein networks gives insight into their underlying design principles. Here, we discuss the excitonic energy transfer mechanisms of the photosystem ... -
The Efficiency of Investment in the Presence of Aggregate Demand Spillovers
(University of Chicago Press, 1988)In the presence of aggregate demand spillovers, an imperfectly competitive firm's profit is positively related to aggregate income, which in turn rises with profits of all firms in the economy. This pecuniary externality ... -
Efficiency of linear estimators under heavy-tailedness: convolutions of [alpha]-symmetric distributions.
(Cambridge University Press, 2007)This paper focuses on the analysis of efficiency, peakedness, and majorization properties of linear estimators under heavy-tailedness assumptions. We demonstrate that peakedness and majorization properties of log-concavely ... -
Efficiency of Magnetic to Kinetic Energy Conversion in a Monopole Magnetosphere
(IOP Publishing, 2009)Unconfined relativistic outflows from rotating, magnetized compact objects are often well modeled by assuming that the field geometry is approximately a split-monopole at large radii. Earlier work has indicated that such ... -
An Efficiency-Wage Theory of the Weather
(University of Chicago Press, 1989)No abstract provided. -
An Efficient Algorithm for Gray-to-Binary Permutation on Hypercubes
(1992)Both Gray code and binary code are frequently used in mapping arrays into hypercube architectures. While the former is preferred when communication between adjacent array elements is needed, the latter is preferred for ... -
Efficient All-Optical Switching Using Slow Light within a Hollow Fiber
(American Physical Society, 2009)We demonstrate a fiber-optical switch that is activated at tiny energies corresponding to a few hundred optical photons per pulse. This is achieved by simultaneously confining both photons and a small lasercooled ensemble ... -
Efficient Allocations under Ambiguity
(Elsevier, 2011)Important implications of the expected utility hypothesis and risk aversion are that if agents have the same probability belief, then consumption plans in every efficient allocation of resources under uncertainty are ... -
An Efficient and Practical Radiosynthesis of [11C] Temozolomide
(American Chemical Society (ACS), 2012)Temozolomide (TMZ) is a prodrug for an alkylating agent used for the treatment of malignant brain tumors. A positron emitting version, [11C]TMZ, has been utilized to help elucidate the mechanism and biodistribution of TMZ. ... -
Efficient and specific gene knockdown by small interfering RNAs produced in bacteria
(2013)Synthetic small interfering RNAs (siRNAs) are an indispensable tool to investigate gene function in eukaryotic cells1,2 and may be used for therapeutic purposes to knockdown genes implicated in disease3. Thus far, most ... -
Efficient construction of sequence-specific TAL effectors for modulating mammalian transcription
(Nature Publishing Group, 2011)The ability to direct functional proteins to specific DNA sequences is a long-sought goal in the study and engineering of biological processes. Transcription activator–like effectors (TALEs) from Xanthomonas sp. are ... -
Efficient C•G-to-G•C base editors developed using CRISPRi screens, target-library analysis, and machine learning

Efficient Data Parallel Implementations of Highly Irregular Problems
(1997)This dissertation presents optimization techniques for efficient data parallel formulation/implementation of highly irregular problems, and applies the techniques to O(N) hierarchical N–body methods for large–scale N–body ... -
Efficient Delivery of Genome-Editing Proteins In Vitro and In Vivo
(2014)Efficient intracellular delivery of proteins is needed to fully realize the potential of protein therapeutics. Current methods of protein delivery commonly suffer from low tolerance for serum, poor endosomal escape, and ... -
Efficient delivery of genome-editing proteins using bioreducible lipid nanoparticles
(Proceedings of the National Academy of Sciences, 2016)A central challenge to the development of protein-based therapeutics is the inefficiency of delivery of protein cargo across the mammalian cell membrane, including escape from endosomes. Here we report that combining ... -
An Efficient Directed Claisen Reaction Allows for Rapid Construction of 5,6-Disubstituted 1,3-Dioxin-4-ones
(Thieme Publishing Group, 2015)An efficient directed Claisen reaction between tert-butyl propionate and phenyl propionate is described. This enables a practical synthesis of 6-ethyl-2,2,5-trimethyl-4H-1,3-dioxin-4-one and thereby (Z)-[(4-ethylidene-2, ... -
Efficient electron spin manipulation in a quantum well by an in-plane electric field
(AIP Publishing, 2003)Electron spins in a semiconductor quantum well couple to an electric field via spin–orbit interaction. We show that the standard spin–orbit coupling mechanisms can provide extraordinarily efficient electron spin manipulation ... -
Efficient encapsulation with plug-triggered drop formation
(American Physical Society, 2011)Monodisperse microscale drops formed with microfluidic devices are useful for encapsulating cells, microgel particles, or even additional drops. These techniques are thus useful for applications ranging from high-throughput ... -
Efficient generation of jets from magnetically arrested accretion on a rapidly spinning black hole
(Oxford University Press (OUP), 2011)We describe global, 3D, time‐dependent, non‐radiative, general‐relativistic, magnetohydrodynamic simulations of accreting black holes (BHs). The simulations are designed to transport a large amount of magnetic flux to the ... -
Efficient Image Reconstruction for Gigapixel Quantum Image Sensors
(IEEE, 2014)Recent advances in materials, devices and fabrication technologies have motivated a strong momentum in developing solid-state sensors that can detect individual photons in space and time. It has been envisioned that such ...
