Quantum criticality of the sub-ohmic spin-boson model

, 2011
We revisit the critical behavior of the sub-ohmic spin-boson model. Analysis of both the leading and subleading terms in the temperature dependence of the inverse static local spin susceptibility at the quantum critical point, calculated using a ...

The Influence of Agritourism Experiences on Consumer Behavior toward Local Food

Journal of Travel Research, 2020
Agritourism—visiting a working farm for education or recreation—may serve as a tool to increase local food consumption as it often includes opportunities to purchase local food on-site.

Estimating Differential Responses to Local Fiscal Conditions: A Mixture Model Analysis [PDF]

, 2003
Alternative hypotheses exist regarding the impact of local sales and income taxes on local governments' taxing and spending decisions. One hypothesis is that local governments use sales and income taxes to pay for spending increases and leave property ...

Quantum tunneling on graphs

, 2011
We explore the tunneling behavior of a quantum particle on a finite graph, in the presence of an asymptotically large potential. Surprisingly the behavior is governed by the local symmetry of the graph around the wells.Comment: 18 ...

Effect of extreme data loss on long-range correlated and anti-correlated signals quantified by detrended fluctuation analysis

, 2010
We investigate how extreme loss of data affects the scaling behavior of long-range power-law correlated and anti-correlated signals applying the DFA method.

Local behavior of traces of Besov functions: Prevalent results [PDF]

, 2010
Let $1 \leq d < D$ and $(p,q,s)$ satisfying $0 < p < \infty$, $0 < q \leq \infty$, $0 < s-d/p < \infty$. In this article we study the global and local regularity properties of traces, on affine subsets of $\R^D$, of functions belonging to the Besov space

An experimental study of coupling between combustor pressure, fuel/air mixing, and the flame [PDF]

, 2005
Fuel-air mixing behavior under the influence of imposed acoustic oscillations has been studied by investigating the response of the fuel mixture fraction field.

Long range order and two-fluid behavior in heavy electron materials

, 2012
The heavy electron Kondo liquid is an emergent state of condensed matter that displays universal behavior independent of material details. Properties of the heavy electron liquid are best probed by NMR Knight shift measurements, which provide a direct ...

Local approximation behavior of modified SMK operators [PDF]

Miskolc Mathematical Notes, 2010
In this paper, for a general modification of the classical Szasz-Mirakjan-Kantorovich operators, we obtain many local approximation results including the classical cases. In particular, we obtain a Korovkin theorem, a Voronovskaya theorem, and some local estimates for these operators.

Porosity suppression of nickel-based superalloy by modulated base temperature in laser welding and mechanism analysis

Journal of Materials Research and Technology
This paper investigates the distribution pattern of welding porosity defects in annular weld seams of superalloy during laser welding. The results reveal that the initial portion of the annular weld seam exhibits a higher density and larger size of ...
