`t Hooft Anomaly Matching for QCD [PDF]

open access: yes, 1997
I present a set of theories which display non-trivial `t Hooft anomaly matching for QCD with $F$ flavors. The matching theories are non-Abelian gauge theories with "dual" quarks and baryons, rather than the purely confining theories of baryons that `t ...

Clinical signs and symptoms of tinnitus in temporomandibular joint disorders: A pilot study comparing patients and non-patients

open access: yesSouth African Journal of Communication Disorders, 2013
Background: Tinnitus is one of the otologic symptoms commonly reported to be associated with temporomandibular disorder (TMD), and questions regarding its nature and cause continue to plague the clinical and research community.

Flat Nonholonomic Matching [PDF]

open access: yes, 2002
In this paper we extend the matching technique to a class of nonholonomic systems with symmetries. Assuming that the momentum equation defines an integrable distribution, we introduce a family of reduced systems.

Informational Matching [PDF]

open access: yesSSRN Electronic Journal, 2002
This paper analyzes the problem of matching heterogenous agents in a Bayesian learning model. One agent gives a noisy signal to another agent, who is responsible for learning. If production has a strong informational component, a phase of cross-matching occurs, so that agents of low knowledge catch up with those of higher one.

Popular Matchings [PDF]

open access: yesSIAM Journal on Computing, 2007
We consider the problem of matching a set of applicants to a set of posts, where each applicant has a preference list, ranking a non-empty subset of posts in order of preference, possibly involving ties. We say that a matching M is popular if there is no matching M' such that the number of applicants preferring M' to M exceeds the number of applicants ...

Do Women Really Face Wage Discrimination on the Labour Market? An Analysis Using Intra-household Specialization

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2014
This study aims to estimate the gender pay gap, cleansed at least partially of the effect of intra-household specialization on productivity. The estimate is based on EU-SILC data for 19 member countries of the European Union.

Near―perfect non-crossing harmonic matchings in randomly labeled points on a circle [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2005
Consider a set $S$ of points in the plane in convex position, where each point has an integer label from $\{0,1,\ldots,n-1\}$. This naturally induces a labeling of the edges: each edge $(i,j)$ is assigned label $i+j$, modulo $n$.

Pairing Optimization via Statistics: Algebraic Structure in Pairing Problems and Its Application to Performance Enhancement

open access: yesEntropy, 2023
Fully pairing all elements of a set while attempting to maximize the total benefit is a combinatorically difficult problem. Such pairing problems naturally appear in various situations in science, technology, economics, and other fields.

Probability Matching [PDF]

open access: yesPsychometrika, 1966
The class of symmetric path-independent models with experimenter-controlled events is considered in conjunction with two-choice probability learning experiments. Various refinements of the notion of probability matching are defined, and the incidence of these properties within this class is studied.
