Quantitative Methods for Stratified Medicine
(2015-05-15)Stratified medicine has tremendous potential to deliver more effective therapeutic intervention to improve public health. For practical implementation, reliable prediction models and clinically meaningful categorization ... -
Quantitative population dynamics of microbial communities in plankton-fed microbial fuel cells
(Springer Nature, 2009)This study examines changes in diversity and abundance of bacteria recovered from the anodes of microbial fuel cells (MFCs) in relation to anode potential, power production and geochemistry. MFCs were batch-fed with plankton, ... -
A Quantitative Study of the Paratexts in Erasmus-Froben Imprints
(Brill, 2021-10-08)We study the paratexts in Erasmus’ imprints with Johann then Hieronymus Froben of Basel between 1514 and 1536. From Valentina Sebastiani’s bibliography of Johann Froben we observe that Erasmus was a more abundant paratexter ... -
Quantitative study of the transmission of axially channeled protons in thin silicon crystals
(American Physical Society (APS), 1978)The azimuthal distributions of protons transmitted through thin silicon single crystals near the ⟨110⟩ axis were measured using a two-dimensional position-sensitive detector. The data are composed of ringlike distributions ... -
A Quantitative Test of Population Genetics Using Spatio-Genetic Patterns in Bacterial Colonies
(University of Chicago Press, 2011)It is widely accepted that population genetics theory is the cornerstone of evolutionary analyses. Empirical tests of the theory, however, are challenging because of the complex relationships between space, dispersal, and ... -
Quantitative-Proteomic Comparison of Alpha and Beta Cells to Uncover Novel Targets for Lineage Reprogramming
(Public Library of Science, 2014)Type-1 diabetes (T1D) is an autoimmune disease in which insulin-secreting pancreatic beta cells are destroyed by the immune system. An emerging strategy to regenerate beta-cell mass is through transdifferentiation of ... -
Quantized biopolymer translocation through nanopores: Departure from simple scaling
(American Physical Society, 2009)We discuss multiscale simulations of long biopolymer translocation through wide nanopores that can accommodate multiple polymer strands. The simulations provide clear evidence of folding quantization, namely the translocation ... -
Quantized Current Blockade and Hydrodynamic Correlations in Biopolymer Translocation through Nanopores: Evidence from Multiscale Simulations
(American Chemical Society, 2008-02-27) -
Quantized Layer Growth at Liquid-Crystal Surfaces
(American Physical Society, 1986)We report x-ray reflectivity measurements on the free surface of dodecylcyanobiphenyl (12CB) at the isotropic to smectic-A phase transition. At about \(10^{\circ}C\) above \(T_{IA}\), smectic-A-like ordering develops at ... -
quantro: a data-driven approach to guide the choice of an appropriate normalization method
(BioMed Central, 2015)Normalization is an essential step in the analysis of high-throughput data. Multi-sample global normalization methods, such as quantile normalization, have been successfully used to remove technical variation. However, ... -
Quantum affine symmetry as generalized supersymmetry

Quantum Algorithm for Molecular Properties and Geometry Optimization
(American Institute of Physics, 2009)Quantum computers, if available, could substantially accelerate quantum simulations. We extend this result to show that the computation of molecular properties (energy derivatives) could also be sped up using quantum ... -
Quantum algorithm for obtaining the energy spectrum of molecular systems
(Royal Society of Chemistry (RSC), 2008)Simulating a quantum system is more efficient on a quantum computer than on a classical computer. The time required for solving the Schro¨ dinger equation to obtain molecular energies has been demonstrated to scale ... -
Quantum and photonic information processing with non-von Neumann architectures
(2022-11-23)Computing and information processing are currently undergoing evolution and change. The development of alternative and non-traditional computing architectures has become increasingly necessary to keep pace with ... -
Quantum approximate optimization of non-planar graph problems on a planar superconducting processor
(Springer Science and Business Media LLC, 2021-02-04)Faster algorithms for combinatorial optimization could prove transformative for diverse areas such as logistics, finance, and machine learning. Accordingly, the possibility of quantum enhanced optimization has driven much ... -
Quantum autoencoders for efficient compression of quantum data
(IOP Publishing, 2017-08-18)Classical autoencoders are neural networks that can learn efficient low dimensional representations of data in higher dimensional space. The task of an autoencoder is, given an input x, is to map x to a lower dimensional ... -
Quantum Bousso bound
(American Physical Society, 2004)The Bousso bound requires that one-quarter of the area of a closed codimension-2 spacelike surface exceeds the entropy flux across a certain lightsheet terminating on the surface. The bound can be violated by quantum effects ... -
Quantum Butterfly Effect in Weakly Interacting Diffusive Metals
(American Physical Society (APS), 2017-09-14)We study scrambling, an avatar of chaos, in a weakly interacting metal in the presence of random potential disorder. It is well known that charge and heat spread via diffusion in such an interacting disordered metal. In ... -
Quantum cascade lasers in chemical physics
(Elsevier BV, 2010)In the short space of 15 years since their first demonstration, quantum cascade lasers have become the most useful sources of tunable mid-infrared laser radiation. This Letter describes these developments in laser ... -
Quantum Cascade Surface-Emitting Photonic Crystal Laser
(American Association for the Advancement of Science, 2003)We combine photonic and electronic band structure engineering to create a surface-emitting quantum cascade microcavity laser. A high-index contrast two-dimensional photonic crystal is used to form a micro-resonator that ...
