Geometric Requirements for Tectorial Membrane Traveling Waves in the Presence of Cochlear Loads
(Elsevier, 2017-02)Recent studies suggest that wave motions of the tectorial membrane (TM) play a critical role in determining the frequency selectivity of hearing. However, frequency tuning is also thought to be limited by viscous loss in ... -
The Geometric Role of Precisely Engineered Imperfections on the Critical Buckling Load of Spherical Elastic Shells
(ASME International, 2016-09)We study the effect of a dimplelike geometric imperfection on the critical buckling load of spherical elastic shells under pressure loading. This investigation combines precision experiments, finite element modeling, and ... -

Geometric Sketching Compactly Summarizes the Single-Cell Transcriptomic Landscape
(Elsevier BV, 2019)Large-scale single-cell RNA sequencing (scRNA-seq) studies that profile hundreds of thousands of cells are becoming increasingly common, overwhelming existing analysis pipelines. Here, we describe how to enhance and ... -
A Geometric Solution to the Coincidence Problem, and the Size of the Landscape as the Origin of Hierarchy
(American Physical Society, 2011-03)Weinberg’s seminal prediction of the cosmological constant relied on a provisional method for regulating eternal inflation which has since been put aside. We show that a modern regulator, the causal patch, improves agreement ... -
Geometric squeezing into the lowest Landau level
(American Association for the Advancement of Science (AAAS), 2021)The equivalence between particles under rotation and charged particles in a magnetic field relates phenomena as diverse as spinning atomic nuclei, weather patterns, and the quantum Hall effect. For such systems, quantum ... -
Geometric Structure of the Adaptive Controller of the Human Arm
(1993-07-01)The objects with which the hand interacts with may significantly change the dynamics of the arm. How does the brain adapt control of arm movements to this new dynamic? We show that adaptation is via composition of a ... -
Geometric theory of nonlinear filtering

A geometric theory of outliers and perturbation
(Massachusetts Institute of Technology, 2002)We develop a new understanding of outliers and the behavior of linear programs under perturbation. Outliers are ubiquitous in scientific theory and practice. We analyze a simple algorithm for removal of outliers from a ... -
Geometric, topological & semantic analysis of multi-building floor plan data
(Massachusetts Institute of Technology, 2006)Generating a comprehensive model of a university campus or other large urban space is a challenging undertaking due to the size, geometric complexity, and levels of rich semantic information contained in inhabited environments. ... -
Geometrical control of domain walls and the study of domain wall properties of materials with perpendicular magnetic anisotropy
(Massachusetts Institute of Technology, 2017)Magnetic based devices such as hard disk drives (HDDs) are widely used in the computer industry because of their high memory capacity, non-volatility and low cost compared to semiconductor-based solid state disk drives ... -
Geometrical effects on axial & azimuthal variations of heat flux to coolant in asymmetrically heated channels
(Cambridge, Mass. : Massachusetts Institute of Technology, Dept. of Nuclear Engineering, [1998], 1998)This report summarizes analyses of the effects of heat conduction in a copper block on the heat flux to a coolant flowing axially in the block. Heat is assumed to be added through one side of the block corresponding to ... -
Geometrical effects on energy transfer in disordered open quantum systems
(American Institute of Physics (AIP), 2013-05)We explore various design principles for efficient excitation energy transport in complex quantum systems. We investigate energy transfer efficiency in randomly disordered geometries consisting of up to 20 chromophores to ... -
Geometrical optimization of arched structures under stochastic loading
(Massachusetts Institute of Technology, 2016)This thesis presents a method for determining the moment-optimized shape y(x) for arched structures under unpredictable loading scenarios. A frame geometry optimization derivation is presented that demonstrates the ... -

Geometrically asymmetric optical cavity for strong atom-photon coupling
(American Physical Society, 2019-01)Optical cavities are widely used to enhance the interaction between atoms and light. Typical designs using a geometrically symmetric structure in the near-concentric regime face a tradeoff between mechanical stability and ... -
Geometrically Calibrated Network Models for Progressive Cavity Pump Design
(Society of Petroleum Engineers (SPE), 2020-12)Linear network models are promisingly simple progressive cavity pump design tools. Current linear network models are difficult to use in the design process because they require calibration against experimental data or ... -
