Stochastic approximation on non-compact measure spaces and application to measure-valued Pólya processes
Our main result is to prove almost-sure convergence of a stochasticapproximation algorithm defined on the space of measures on a noncompact space. Our motivation is to apply this result to measure-valued Pólya processes (MVPPs...
Cellular organization in lab-evolved and extant multicellular species obeys a maximum entropy law
The prevalence of multicellular organisms is due in part to their ability to form complex structures. How cells pack in these structures is a fundamental biophysical issue, underlying their functional properties....

Phase stability and transformations in the halide perovskite CsSnI<sub>3</sub>
We employ the quasiharmonic approximation to study the temperature-dependent lattice dynamics of the four different phases of cesium tin iodide (CsSnI3). Within this framework, we obtain the temperature dependence of...
Modeling and simulation of martensitic phase transitions with a triple point
A framework for modeling complex global energy landscapes in a piecewise manner is presented. Specifically, a class of strain-dependent energy functions is derived for the triple point of Zirconia (ZrO2), where tetragonal...
Renormalon approach to higher twist distribution amplitudes and the convergence of the conformal expansion.
Power corrections to exclusive processes are usually calculated using models for twist–four
distribution amplitudes (DA) which are based on the leading–order terms in the conformal
expansion. In this work we develop a different...

Fabrication of a Horizontal and a Vertical Large Surface Area Nanogap Electrochemical Sensor
Nanogap sensors have a wide range of applications as they can provide accurate direct detection of biomolecules through impedimetric or amperometric signals. Signal response from nanogap sensors is dependent on both the...
Elite solidarity, social responsibility, and the contested origins of Britain’s first business schools
Britain is often depicted as a laggard in management education before the late creation of two graduate business schools in London and Manchester in the mid-1960s triggered the emergence of a new academic sector. According to...
Twistors, the ASD Yang-Mills equations and 4d Chern-Simons theory
Abstract
We show that the approaches to integrable systems via 4d Chern-Simons theory and via symmetry reductions of the anti-self-dual Yang-Mills...

Preconditioners and Tensor Product Solvers for Optimal Control Problems from Chemotaxis
In this paper, we consider the fast numerical solution of an optimal control formulation of the Keller--Segel model for bacterial chemotaxis. Upon discretization, this problem requires the solution of huge-scale saddle point...
Comparison of the Protein Contents of Bovine Zymogen Granules and of Pancreatic Juice
Lewis Joel Greene
Jan 01, 0001
A zymogen granule fraction has been isolated from bovine pancreas by differential centrifugation under conditions designed to favor homogeneity at the expense of yield. The fraction has been examined in the electron microscope...

Expressive and receptive language effects of African American English on a sentence imitation task
This study tests the extent to which giving credit for African American English (AAE) responses on a General American English sentence imitation test mitigates dialect effects. Forty-eight AAE-speaking second graders completed...
Strontium migration assisted by oxygen vacancies in SrTiO3 from classical and quantum mechanical simulations
We present the pathways for strontium ion migration in SrTiO3, which are based on an exploration of the potential energy landscape through a combination of classical and quantum mechanical techniques. Sr ion migration is...

The current decay in response to a sudden change of applied bias up to 1 V has been measured on a methylammonium lead triiodide perovskite solar cell with titania and spiro-OMeTAD transport layers, for temperatures between 258...
Eco-friendly synthesis and catalytic application of chitosan/gold/carbon nanotube nanocomposite films
Novel eco-friendly chitosan nanocomposite membranes containing gold nanoparticles and carbon nanotubes (CNTs) have been synthesized. The catalytic activity of the nanocomposites was explored using a model reduction reaction of...

Currently, there is no available needle-free approach for diabetics to monitor glucose levels in the interstitial fluid. Here, we report a path-selective, non-invasive, transdermal glucose monitoring system based on a...
Load Characterization and Low-order Approximation for Smart Metering Data in the Spectral Domain
Smart metering data are providing new opportunities for various energy analyses at household level. However traditional load analyses based on time-series techniques are challenged due to the irregular patterns and large volume...
On the relative energies of the Rivlin and cavitation instabilities for compressible materials
In 1948, Rivlin showed that if a cube of incompressible neo-Hookean material is subjected to a sufficiently large uniform normal dead-load on its boundary, then an asymmetric deformation is the minimizer of the energy in the...

Existence and homogenisation of travelling waves bifurcating from resonances of reaction-diffusion equations in periodic media
The existence of travelling wave type solutions is studied for a scalar reaction diffusion equation in R2 with a nonlinearity which depends periodically on the spatial variable. We treat the coefficient of the linear term as a...
Increased methane emissions from deep osmotic and buoyant convection beneath submarine seeps as climate warms.
High speeds have been measured at seep and mud-volcano sites expelling methane-rich fluids from the seabed. Thermal or solute-driven convection alone cannot explain such high velocities in low-permeability sediments. Here we...
