Thermodynamics and transport of holographic nodal line semimetals

open access: yesJournal of High Energy Physics, 2021
We study various thermodynamic and transport properties of a holographic model of a nodal line semimetal (NLSM) at finite temperature, including the quantum phase transition to a topologically trivial phase, with Dirac semimetal-like conductivity.

Semi-supervised learning approach for localization and pose estimation of texture-less objects in cluttered scenes

open access: yesArray, 2022
3D object recognition and 6D pose estimation are crucial and fundamental endeavours for industrial assembly line automation such as robotic controlled pick-and-place.

Adaptive detection of a signal known only to lie on a line in a known subspace, when primary and secondary data are partially homogeneous [PDF]

open access: yes, 2006
This paper deals with the problem of detecting a signal, known only to lie on a line in a subspace, in the presence of unknown noise, using multiple snapshots in the primary data.

Single-base station hybrid positioning algorithm based on LOS identification

open access: yesEURASIP Journal on Wireless Communications and Networking, 2023
In the complex multipath propagation environment, whether there is a line of sight (LOS) path will directly affect the positioning accuracy. Therefore, this paper proposes a single base station hybrid positioning algorithm based on LOS identification. In

Five-Brane Effective Action In M-Theory [PDF]

open access: yes, 1996
On the world-volume of an $M$-theory five-brane propagates a two-form with self-dual field strength. As this field is non-Lagrangian, there is no obvious framework for determining its partition function.

On Families QSL $$_{\ge 2}$$ of Quadratic Systems with Invariant Lines of Total Multiplicity At Least 2

open access: yesQualitative Theory of Dynamical Systems, 2022
Let QSLge;inbsp;be the family of quadratic differential systems with invariant lines of total multiplicity at least i and let QSLinbsp;denote the family of quadratic systems with invariant lines of total multiplicity exactly i. For any polynomial system the line at infinity is invariant. Thus the family QS of all quadratic systems is the same as QSLge;

Hybrid nodal-chain semimetal with emergent flat band in MgCaN2

open access: yesNew Journal of Physics, 2023
The distinct over-tiltings of band crossings in topological semimetals generate the type-I and type-II classification of Dirac/Weyl and nodal-line fermions, accompanied by exotic electronic and magnetic transport properties.

Packing a cake into a box [PDF]

open access: yes, 2010
Given a cake in form of a triangle and a box that fits the mirror image of the cake, how to cut the cake into a minimal number of pieces so that it can be put into the box?

Discovery of Power-Law Growth in the Self-Renewal of Heterogeneous Glioma Stem Cell Populations. [PDF]

open access: yesPLoS ONE, 2015
Accumulating evidence indicates that cancer stem cells (CSCs) drive tumorigenesis. This suggests that CSCs should make ideal therapeutic targets. However, because CSC populations in tumors appear heterogeneous, it remains unclear how CSCs might be ...

A topological invariant of line arrangements [PDF]

open access: yes, 2014
We define a new topological invariant of line arrangements in the complex projective plane. This invariant is a root of unity defined under some combinatorial restrictions for arrangements endowed with some special torsion character on the fundamental ...
