Bottom-Up Estimates of Coal Mine Methane Emissions in China: A Gridded Inventory, Emission Factors, and Trends
(American Chemical Society (ACS), 2019-05-31)China has large but uncertain coal mine methane (CMM) emissions. Inverse modeling (top-down) analyses of atmospheric methane observations can help improve the emission estimates but require reliable emission patterns as ... -
A bottom-up perspective on ecosystem change in Mesozoic oceans
(The Royal Society, 2016)Mesozoic and Early Cenozoic marine animals across multiple phyla record secular trends in morphology, environmental distribution, and inferred behaviour that are parsimoniously explained in terms of increased selection ... -
Bound states at impurities as a probe of topological superconductivity in nanowires
(American Physical Society, 2013)Spin-orbit coupled superconductors are interesting candidates for realizing topological and potentially non-Abelian states with Majorana fermions. We argue that time-reversal broken spin-orbit coupled superconductors ... -
Bound states in two spatial dimensions in the noncentral case
(AIP Publishing, 2004) -
Bound States of Guided Matter Waves: An Atom and a Charged Wire
(American Physical Society, 1992)We argue that it is possible to bind a neutral atom in stable orbits around a wire charged by a time-varying sinusoidal voltage. Both classical and quantum-mechanical theories for this system are discussed, and a unified ... -
Boundary Work for Sustainable Development: Natural Resource Management at the Consultative Group on International Agricultural Research (CGIAR)
(National Academy of Sciences, 2011)Previous research on the determinants of effectiveness in knowledge systems seeking to support sustainable development has highlighted the importance of “boundary work” through which research communities organize their ... -

Bounded Independence Fools Degree-2 Threshold Functions
(IEEE, 2010)For an n-variate degree-2 real polynomial p, we prove that \(E_{x\sim D}[sig(p(x))]\) Is determined up to an additive \(\epsilon\) as long as D is a k-wise Independent distribution over \(\{-1, 1\}^n\) for \(k = ... -
Bounded Rationality

Bounding the costs of quantum simulation of many-body physics in real space
(IOP Publishing, 2017-06-29)We present a quantum algorithm for simulating the dynamics of a first-quantized Hamiltonian in real space based on the truncated Taylor series algorithm. We avoid the possibility of singularities by applying various cutoffs ... -
Bounds and Improvements for BiBa Signature Schemes
(2002)This paper analyzes and improves the recently proposed bins and balls signature (BiBa [23]), a new approach for designing signatures from one-way functions without trapdoors. We first construct a general framework for ... -
Bounds on Elasticities With Optimization Frictions: A Synthesis of Micro and Macro Evidence on Labor Supply
(Blackwell Publishing Limited, 2012)How can price elasticities be identified when agents face optimization frictions such as adjustment costs or inattention? I derive bounds on structural price elasticities that are a function of the observed effect of a ... -
Bounds on nanoscale nematicity in single-layerFeSe/SrTiO3
(American Physical Society (APS), 2016)We use scanning tunneling microscopy (STM) and quasiparticle interference (QPI) imaging to investigate the low-energy orbital texture of single-layer FeSe/SrTiO3. We develop a T -matrix model of multiorbital QPI to disentangle ... -

Bow Shocks, Wiggling Jets, and Wide‐Angle Winds: A High‐Resolution Study of the Entrainment Mechanism of the PV Cephei Molecular (CO) Outflow
(American Astronomical Society, 2002)We present a new set of high-resolution molecular-line maps of the gas immediately surrounding various Herbig-Haro (HH) knots of the giant HH flow HH 315 from the young star PV Cephei. The observations, aimed at studying ... -
BPS degeneracies and superconformal index in diverse dimensions
(American Physical Society, 2014)We present a unifying theme relating BPS partition functions and superconformal indices. In the case with complex supersymmetry central charges (as in N = 2 in d = 4 and N = (2, 2) in d = 2), the known results can be ... -
BPS microstates and the open topological string wave function
(International Press, 2006)It has recently been conjectured that the closed topological string wave function computes a grand canonical partition function of Bogomol'nyi-Prasad-Sommerfield (BPS) black hole states in four dimensions: Z(BH) = vertical ... -
BPTree: An ℓ2 Heavy Hitters Algorithm Using Constant Memory
(2017)The task of finding heavy hitters is one of the best known and well studied problems in the area of data streams. One is given a list i1,i2,...,im∈[n] and the goal is to identify the items among [n] that appear frequently ... -
The brachymorph mouse and human evolution
(John Wiley & Sons, 2005)The degree to which evolutionary change in the cranial base was an integrative influence on other aspects of craniofacial evolution in hominids is a subject of much debate. Using a mouse model, we test the hypothesis that ...
