w 1+∞ and Carrollian holography

open access: yesJournal of High Energy Physics
In a 1 + 2D Carrollian conformal field theory, the Ward identities of the two local fields S 0 + $$ {S}_0^{+} $$ and S 1 + $$ {S}_1^{+} $$ , entirely built out of the Carrollian conformal stress-tensor, contain respectively up to the leading and the ...

Boundary Algebra: A Simple Notation for Boolean Algebra and the Truth Functors [PDF]

open access: yes
Boundary algebra [BA] is a simpler notation for Spencer-Brown’s (1969) primary algebra [pa], the Boolean algebra 2, and the truth functors. The primary arithmetic [PA] consists of the atoms ‘()’ and the blank page, concatenation, and enclosure between ‘(‘

Review and prospects of shear test of bolted rock joints

open access: yesDeep Underground Science and Engineering, EarlyView.
The laboratory shear test equipment, test method, and numerical simulation of bolted rock joints were summarized. The shortcomings and limitations of the current research were analyzed, and the research prospects were proposed. Abstract Rock bolting is a critical approach in geotechnical engineering for supporting weak rocks.

On upper modular subalgebras of a Lie algebra. [PDF]

open access: yes, 2004
This paper is a further contribution to the extensive study by a number of authors of the subalgebra lattice of a Lie algebra. We give some necessary and some sufficient conditions for a subalgebra to be upper modular.

Immersed Boundary Projection Method for Boundaries With Slip Velocities

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
A formulation of the immersed boundary method for incompressible flow over arbitrarily‐shaped bodies with surface slip described by the Navier boundary condition is presented. The wall slip velocity and the boundary force are determined implicitly through a projection to satisfy both the boundary condition and the divergence‐free condition of the ...

Fabrication and characterisation of novel Ge MOSFETs [PDF]

open access: yes
As high-k dielectrics are introduced into commercial Si CMOS (Complimentary Metal Oxide Semiconductor) microelectronics, the 40 year channel/dielectric partnership of Si/SiO2 is ended and the door opened for silicon to be replaced as the active channel ...

A Multi‐Objective Periodic Vehicle Routing Model for Sustainable Healthcare Waste Collection

open access: yesThe International Journal of Health Planning and Management, EarlyView.
ABSTRACT The collection of infectious waste from healthcare facilities (HCF) constitutes a recurring operational challenge. Indeed, despite the inherent health risks posed by the storage and the transportation of infectious materials, most of the existing waste collection systems tends to prioritise cost optimization and to underaddress the safety ...

Routing Leakage in Adaptive Coded Distributed Matrix Multiplication: An Information-Theoretic Framework for Conditional Differential Privacy

open access: yesIEEE Access
Coded distributed computing enables efficient and fault-tolerant execution of large-scale linear algebra tasks, but introduces new privacy risks when routing decisions depend on encoded data.

Catalan Bounds for Symmetric Strength‐Two Orthogonal Arrays

open access: yesJournal of Combinatorial Designs, EarlyView.
ABSTRACT A Hamming shell construction is a two‐level array obtained by taking every binary vector of a given Hamming weight a prescribed number of times, for each weight in turn. Such arrays are invariant under all permutations of the factors, and they are strength‐two orthogonal arrays exactly when the multiplicities satisfy three linear constraints ...

Representations of the marked Brauer algebra [PDF]

open access: yes, 2017
The marked Brauer algebra is a generalization of the diagrammatic Brauer algebra which diagrammatizes Moon's centralizer algebra for the type \mathfrak{p} Lie superalgebra.
