• #### Adiabatic quantum optimization in the presence of discrete noise: Reducing the problem dimensionality ﻿

(American Physical Society (APS), 2015)
Adiabatic quantum optimization is a procedure to solve a vast class of optimization problems by slowly changing the Hamiltonian of a quantum system. The evolution time necessary for the algorithm to be successful scales ...
• #### Adiabatic Quantum Simulation of Quantum Chemistry ﻿

(Nature Publishing Group, 2014)
We show how to apply the quantum adiabatic algorithm directly to the quantum computation of molecular properties. We describe a procedure to map electronic structure Hamiltonians to 2-body qubit Hamiltonians with a small ...
• #### Adiabatic Quantum Simulators ﻿

(2011)
In his famous 1981 talk, Feynman proposed that unlike classical computers, which would presumably experience an exponential slowdown when simulating quantum phenomena, a universal quantum simulator would not. An ideal ...
• #### Advanced atomic layer deposition and epitaxy processes ﻿

(2015)
Atomic Layer Deposition (ALD) was used to grow single-crystalline epitaxial layers of high-k dielectric oxides on semiconductors with remarkably few defects or traps at the interfaces. La2O3 on GaAs(111) produced record-breaking ...
• #### Advanced Metallization Processes for Complex Structures in Microelectronics by Direct-Liquid-Evaporation Chemical Vapor Deposition ﻿

(2017-07-27)
With the rapid advancement of semiconductor industry, fabrications of complex microelectronic devices are going beyond the conventional planar geometries into three-dimensionality (3D). Besides, since the emerging of ...
• #### Advanced Physical Techniques in Inorganic Chemistry: Probing Small Molecule Activation ﻿

(2016-05-16)
Robust and efficient catalysts are necessary for realizing chemical energy storage as a solution for the intermittency associated with renewable energy sources. To aid in the development of such catalysts, physical methods ...
• #### Advances in Crystal Growth and Assembly for Imparting Novel Photonic Properties to Semiconductor Nanowires ﻿

(2015-08-17)
Semiconductor nanowires comprise a versatile materials platform with which to characterize the properties of nanomaterials. The vast range of structural and compositional diversity of nanowires has also enabled their use ...
• #### Advancing Biological Understanding and Therapeutics Discovery with Small-Molecule Probes ﻿

(Elsevier BV, 2015)
Small-molecule probes can illuminate biological processes and aid in the assessment of emerging therapeutic targets by perturbing biological systems in a manner distinct from other experimental approaches. Despite the ...

• #### AlGaN/GaN MOSHEMT on Si Substrate with High on/off Ratio and High Off-state Breakdown Voltage Enabled by Atomic Layer Epitaxial MgCaO as Gate Dielectric ﻿

(2016-10-13)
• #### All-Atom Model for Stabilization of α-Helical Structure in Peptides by Hydrocarbon Staples ﻿

(American Chemical Society (ACS), 2009)
Recent work has shown that the incorporation of an all-hydrocarbon “staple” into peptides can greatly increase their α-helix propensity, leading to an improvement in pharmaceutical properties such as proteolytic stability, ...
• #### All-Optical Interrogation of Neural Circuits ﻿

(Society for Neuroscience, 2015)
There have been two recent revolutionary advances in neuroscience: First, genetically encoded activity sensors have brought the goal of optical detection of single action potentials in vivo within reach. Second, optogenetic ...
• #### Allene Synthesis from 2-Alkyn-1-Ols ﻿

(Elsevier, 1989)
Activation of 2-alkyn-1-01s as their methanesulfonate esters and displacement with hydrazine urnishes the corresponding alkynyl hydrazine derivatives which undergo smooth oxidative rearrangement with diethyl azodicarboxylate ...
• #### Allosteric Communication in Myosin V: From Small Conformational Changes to Large Directed Movements ﻿

(Public Library of Science, 2008)
The rigor to post-rigor transition in myosin, a consequence of ATP binding, plays an essential role in the Lymn–Taylor functional cycle because it results in the dissociation of the actomyosin complex after the powerstroke. ...
• #### Alternating layer addition approach to CdSe/CdS core/shell quantum dots with near-unity quantum yield and high on-time fractions ﻿
