On the Origin of Model Relations among Transverse-Momentum Dependent Parton Distributions [PDF]
Transverse-momentum dependent parton distributions (TMDs) are studied in the framework of quark models. In particular, quark-model relations among TMDs are reviewed, elucidating their physical origin in terms of the quark-spin structure in the nucleon ...

Higher Derivatives and Canonical Formalisms [PDF]
Path integral expressions for three canonical formalisms -- Ostrogradski's one, constrained one and generalized one -- of higher-derivative theories are given. For each fomalism we consider both nonsingular and singular cases. It is shown that three formalisms share the same path integral expressions. In paticular it is pointed out that the generalized

Modernity and morality in Habermas's discourse ethics [PDF]
Discourse ethics is originally conceived as a programme of philosophical justification of morality. This depends on the formal derivation of the moral principle (U) from non-moral principles. The moral theory is supposed to fall out of a pragmatic theory

La derivación verbal apreciativa en español
This paper analyzes the verb formation by means of the called, in Spanish, affixal «apreciativos». The paper is split into three subparts that are occupied by others so man y facets of this type of derivation.

Higher Derivative Gravity in Generalized Covariant Derivative Formalism [PDF]
Field strength (‘curvature’ tensor in mathematical terms) is one of the key concepts in gauge theory. To develop a new unified theory of the gauge and Higgs fields, a “field strength” is introduced for the Higgs field by generalizing covariant derivatives for chiral multi-spinor fields so as to include the Dirac γ-matrices.

A power distribution system is usually composed of a number of distribution substations and distribution lines, where the latter are fragile and often suffer from faults, leading to serious local power shortages.

A Kinetic Perspective on k - ϵ Turbulence Model and Corresponding Entropy Production
In this paper, we present an alternative derivation of the entropy production in turbulent flows, based on a formal analogy with the kinetic theory of rarefied gas.

Continuum limit of self-driven particles with orientation interaction [PDF]
We consider the discrete Couzin-Vicsek algorithm (CVA), which describes the interactions of individuals among animal societies such as fish schools.

Formal derivation of a pattern matching algorithm
The functional version of the Knuth-Morris-Pratt pattern matching algorithm is formally derived using the Bird's calculus of lists. The derivation process is thoroughly explained, various solving strategies are discussed, the paper is self-contained.
