• #### W-Jet Tagging: Optimizing the Identification of Boosted Hadronically-Decaying W Bosons ﻿

(American Physical Society, 2011)
A method is proposed for distinguishing highly boosted hadronically-decaying $W's$ $(W jets)$ from QCD-jets using jet substructure. Previous methods, such as the filtering/mass-drop method, can give a factor of \(\sim ...
• #### The Waddesdon Psalter and the Shop of Jean Pucelle ﻿

(Deutscher Kunstverlag GmbH, 1981)
• #### Wafer-scale metasurface for total power absorption, local field enhancement and single molecule Raman spectroscopy ﻿

(Nature Publishing Group, 2013)
The ability to detect molecules at low concentrations is highly desired for applications that range from basic science to healthcare. Considerable interest also exists for ultrathin materials with high optical absorption, ...
• #### Wage-Employment Contracts ﻿

(MIT Press, 1983)
This paper studies the efficient agreements about the dependence of workers' earnings on employment, when the employment level is controlled by firms. The firms' superior information about profitability conditions is ...
• #### Walking the Tightrope on Medicare Reform ﻿

(American Economic Association, 2000)
A central controversy in the debate about Medicare is whether the program spends too much money or whether instead it should be expanded to cover more. I consider the value of increased Medicare spending. I argue that on ...
• #### Walking, running and the evolution of short toes in humans ﻿

(The Company of Biologists, 2009)
The phalangeal portion of the forefoot is extremely short relative to body mass in humans. This derived pedal proportion is thought to have evolved in the context of committed bipedalism, but the benefits of shorter toes ...
• #### Wall Crossing and M-theory ﻿

(European Mathematical Society, 2011)
We study BPS bound states of D0 and D2 branes on a single D6 brane wrapping a Calabi-Yau 3-fold X. When X has no compact 4-cyles, the BPS bound states are organized into a free field Fock space, whose generators correspond ...
• #### Wall mechanics and exocytosis define the shape of growth domains in fission yeast ﻿

(Nature Pub. Group, 2015)
The amazing structural variety of cells is matched only by their functional diversity, and reflects the complex interplay between biochemical and mechanical regulation. How both regulatory layers generate specifically ...
• #### Wall-Crossing from Supersymmetric Galaxies ﻿

(Springer, 2012)
We give an elementary physical derivation of the Kontsevich-Soibelman wall crossing formula, valid for any theory with a 4d N = 2 supergravity description. Our argument leads to a slight generalization of the formula, which ...
• #### The Walls of Jericho: An Alternative Interpretation ﻿

(University of Chicago Press, 1986)
• #### Wandering in the Lyman-Alpha Forest: A Study of Dark Matter-Dark Radiation Interactions ﻿

(IOP Publishing, 2017-09-04)
The amplitude of large-scale matter fluctuations inferred from the observed Sunyaev-Zeldovich (SZ) cluster mass function and from weak gravitational lensing studies, when taken at face value, is in tension with measurements ...
• #### A Wandering Mind Is an Unhappy Mind ﻿

(American Association for the Advancement of Science (AAAS), 2010)
We developed a smartphone technology to sample people’s ongoing thoughts, feelings, and actions and found (i) that people are thinking about what is not happening almost as often as they are thinking about what is and (ii) ...
• #### Wang Anshi and the Zhou li ﻿

(Brill, 2010)
• #### The Wang-Landau algorithm in general state spaces: applications and convergence analysis ﻿

(Institute of Statistical Science, Academia Sinica, 2010)
The Wang-Landau algorithm (Wang and Landau (2001)) is a recent Monte Carlo method that has generated much interest in the Physics literature due to some spectacular simulation performances. The objective of this paper is ...
• #### War and first onset of suicidality: the role of mental disorders ﻿

(Cambridge University Press (CUP), 2012)
Background Suicide rates increase following periods of war; however, the mechanism through which this occurs is not known. The aim of this paper is to shed some light on the associations of war exposure, mental disorders, ...
• #### War and Peace: The Evolution of Modern Personnel Administration in U.S. Industry ﻿

(University of Chicago Press, 1986)
This paper charts the transformation of the employment relationship in different industries during the second quarter of this century and is based on a representative sampling of U.S. business organizations. The first ...
• #### War increases religiosity ﻿

(Springer Science and Business Media LLC, 2019-01-28)
Does the experience of war increase people’s religiosity? Much evidence supports the idea that particular religious beliefs and ritual forms can galvanize social solidarity and motivate in-group cooperation, thus facilitating ...
• #### War, Peace, and the Size of Countries ﻿

(Elsevier, 2005)
This paper studies the relationship between international conflict and the size distribution of countries in a model in which both peaceful bargaining and nonpeaceful confrontations are possible. We show how the size ...
• #### Warfare and reproductive success in a tribal population ﻿

(Proceedings of the National Academy of Sciences, 2014)
ntergroup conflict is a persistent feature of many human societies yet little is known about why individuals participate when doing so imposes a mortality risk. To evaluate whether participation in warfare is associated ...
• #### Warm Spitzer Observations of Three Hot Exoplanets: Xo-4b, Hat-p-6b, and Hat-p-8b ﻿

(American Astronomical Society, 2012)
We analyze Warm Spitzer/Infrared Array Camera observations of the secondary eclipses of three planets, XO-4b, HAT-P-6b, and HAT-P-8b. We measure secondary eclipse amplitudes at 3.6 mu m and 4.5 mu m for each target. XO-4b ...
