Macroscopic strings as heavy quarks: Large-N gauge theory and anti-de Sitter supergravity [PDF]
, 1998 . We study some aspects of Maldacena's large-N correspondence between ${\cal N}=4$ superconformal gauge theory on the D3-brane and maximal supergravity on AdS$_5 \times S_5$ by introducing macroscopic strings as heavy (anti-) quark probes.

Physical Review LettersWe propose the gauge theory bootstrap, a method to compute the pion S matrix that describes the low-energy physics of the strong interaction and other similar gauge theories. The phase shifts of the S0, P1, and S2 waves obtained are in good agreement with experimental results.

Network topology drives population temporal variability in experimental habitat networks
Population Ecology, EarlyView.Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

On jet quenching parameters in strongly coupled non-conformal gauge theories [PDF]
, 2006 Recently Liu, Rajagopal and Wiedemann (LRW) [hep-ph/0605178] proposed a first principle, nonperturbative quantum field theoretic definition of ``jet quenching parameter'' \hat{q} used in models of medium-induced radiative parton energy loss in nucleus ...

M2-brane surface operators and gauge theory dualities in Toda [PDF]
, 2014 A bstractWe give a microscopic two dimensional N$$ \mathcal{N} $$ = (2, 2) gauge theory description of arbitrary M2-branes ending on Nf M5-branes wrapping a punctured Riemann surface. These realize surface operators in four dimensional N$$ \mathcal{N} $$

Hydrodynamic gradient expansion in gauge theory plasmas. [PDF]
Physical Review Letters, 2013 We utilize the fluid-gravity duality to investigate the large order behavior of hydrodynamic gradient expansion of the dynamics of a gauge theory plasma system.

Population Ecology, EarlyView.We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year,

Adding Fundamental Matter to ``Chiral Rings and Anomalies in Supersymmetric Gauge Theory'' [PDF]
, 2002 We consider a supersymmetric U(N) gauge theory with matter fields in the adjoint, fundamental and anti-fundamental representations. As in the framework which was put forward by Dijkgraaf and Vafa, this theory can be described by a matrix model.

Conformal invariance of the subleading soft theorem in gauge theory [PDF]
, 2014 In this note, I show that the recently proposed subleading soft factor in massless gauge theory uniquely follows from conformal symmetry of tree-level gauge theory amplitudes in four dimensions.

Moving in the Dark: Enlightening the Spatial Population Ecology of European Cave Salamanders
Population Ecology, EarlyView.We assessed individual interactions, movement ecology and activity patterns of a subterranean population of Speleomantes strinatii, applying spatial capture–recapture modeling to a photographic dataset of 104 individuals. ABSTRACT Space use and movement are fundamental aspects of organisms' ecology, mirroring individual fitness, behavior, and life ...
