Improved Cross-Ratio Invariant-Based Intrinsic Calibration of A Hyperspectral Line-Scan Camera

open access: yesSensors, 2018
Hyperspectral line-scan cameras are increasingly being deployed on mobile platforms operating in unstructured environments. To generate geometrically accurate hyperspectral composites, the intrinsic parameters of these cameras must be resolved.

Prequantization of the Moduli Space of Flat ${\rm PU}(p)$-Bundles with Prescribed Boundary Holonomies [PDF]

open access: yes, 2014
Using the framework of quasi-Hamiltonian actions, we compute the obstruction to prequantization for the moduli space of flat ${\rm PU}(p)$-bundles over a compact orientable surface with prescribed holonomies around boundary components, where $p>2$ is ...

The Transverse-momentum-dependent Parton Distribution Function and Jet Transport in Medium [PDF]

open access: yes, 2008
We show that the gauge-invariant transverse-momentum-dependent (TMD) quark distribution function can be expressed as a sum of all higher-twist collinear parton matrix elements in terms of a transport operator.

Topological study of the para-line graphs of certain pentacene via topological indices

open access: yesOpen Chemistry, 2018
A topological index is a map from molecular structure to a real number. It is a graph invariant and also used to describe the physio-chemical properties of the molecular structures of certain compounds.

Interacting branes, dual branes, and dyonic branes: a unifying lagrangian approach in D dimensions [PDF]

open access: yes, 2000
This paper presents a general covariant lagrangian framework for the dynamics of a system of closed n-branes and dual (D-n-4)-branes in D dimensions, interacting with a dynamical (n+1)-form gauge potential.

CENTER PROBLEM FOR CUBIC DIFFERENTIAL SYSTEMS WITH THE LINE AT INFINITY AND AN AFFINE REAL INVARIANT STRAIGHT LINE OF TOTAL MULTIPLICITY FOUR

open access: yesBukovinian Mathematical Journal, 2021
In this article, we show that a non-degenerate monodromic critical point of differential systems with the line at infinity and an affine real invariant straight line of total multiplicity four is a center type if and only if the first four Lyapunov quantities vanish.

Large Acceptance Spectrometers for Invariant Mass Spectroscopy of Exotic Nuclei and Future Development

open access: yes, 2015
Large acceptance spectrometers at in-flight RI separators have played significant roles in investigating the structure of exotic nuclei. Such spectrometers are in particular useful for probing unbound states of exotic nuclei, using invariant mass ...

Cubic differential systems with invariant straight lines of total multiplicity seven and four real distinct infinite singularities

open access: yesElectronic Journal of Differential Equations, 2021
In this article we consider the class  \(\mathrm{CSL}_7^{4s\infty}\) of non-degenerate real planar cubic vector fields possessing four distinctreal infinite singularities and invariant straight lines, including the line at infinity of total multiplicity 7.

Quartic differential systems with a non-degenerate monodromic critical point and multiple line at infinity

open access: yesActa et Commentationes: Ştiinţe Exacte şi ale Naturii
The quartic differential systems with a non-degenerate monodromic critical point and non-degenerate infinity are considerated. We show that in this family the maximal multiplicity of the line at infinity is seven.
