An improved characterisation of the interior of the completely positive cone [PDF]
The Electronic Journal of Linear Algebra, 2010 A symmetric matrix is defined to be completely positive if it allows a factorisation BB(T), where B is an entrywise nonnegative matrix. This set is useful in certain optimisation problems. The interior of the completely positive cone has previously been characterised by Dur and Still [M. Dur and G. Still, Interior points of the completely positive cone,

Generalized open sets of Minkowski space [PDF]
Mathematica Moravica, 2015 We consider the Euclidean topology and s-topology on n-dimensional Minkowski space and investigate the interior and closure of the space cone and perforated space cone with respect to these topologies.

A polygonal finite element method for shakedown analysis of structures
Vietnam Journal of Mechanics, 2023 This study presents an innovative numerical method that combines the polygonal finite element method (Poly-FEM) with conic optimization techniques within the framework of structural shakedown analysis. The resulting optimization problem is formulated as

Existence of Positive Solutions to Boundary Value Problem of Caputo Fractional Differential Equation
Discrete Dynamics in Nature and Society, 2015 We consider the existence of positive solutions to the nonlinear fractional differential equation boundary value problem D0+αCut+fut,u't=0, t∈0,1, u0=u1=u″0=0, where f:0,+∞×R→0,+∞ is continuous, α∈2,3, and D0+αC is the standard Caputo differentiation ...

GPU-Based Acceleration for Interior Tomography
IEEE Access, 2014 The compressive sensing (CS) theory shows that real signals can be exactly recovered from very few samplings. Inspired by the CS theory, the interior problem in computed tomography is proved uniquely solvable by minimizing the region-of-interest's total ...

A Geodesic Interior-Point Method for Linear Optimization over Symmetric Cones
SIAM Journal on Optimization, 2023 We develop a new interior-point method (IPM) for symmetric-cone optimization, a common generalization of linear, second-order-cone, and semidefinite programming. In contrast to classical IPMs, we update iterates with a geodesic of the cone instead of the kernel of the linear constraints.

Unambiguous observation of vesicle fusion in the interior of a cone [PDF]
, 2020 Abstract When a vesicle was put onto the inner surface of a cone, it would spontaneously move to the bottom of the cone. The mechanism was explained elsewhere. In this work, we showed that when we put two vesicles onto the inner surface of a cone, both of them would spontaneously climb to the bottom of the cone.

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface
FEBS Open Bio, EarlyView.HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral
