Observer-based H∞ control for systems with repeated scalar nonlinearities and multiple packet losses
This paper is concerned with the H∞ control problem for a class of systems with repeated scalar nonlinearities and multiple missing measurements. The nonlinear system is described by a discrete-time state equation involving a repeated scalar nonlinearity,

Lattice study of low-lying nonet scalar mesons in quenched approximation [PDF]
Using lattice QCD simulation in the quenched approximation, we study the κ meson, which is ^3P_0 in the quark model, and compare experimental and other lattice data. The κ is the lowest scalar meson with strangeness and constitutes the scalar nonet.

Charged black holes in a generalized scalar–tensor gravity model
We study 4-dimensional charged and static black holes in a generalized scalar–tensor gravity model, in which a shift symmetry for the scalar field exists.

Stationary scalar hairy configurations supported by Neumann compact stars
We study stationary scalar field hairy configurations supported by asymptotically flat horizonless compact stars. At the star surface, we impose Neumann boundary conditions for the scalar field.

Zero-dimensional models for gravitational and scalar QED decoherence
We investigate the dynamics of two quantum mechanical oscillator system–bath toy models obtained by truncating to zero spatial dimensions linearized gravity coupled to a massive scalar field and scalar quantum electrodynamics (QED).

Polar Quasinormal Modes of Neutron Stars in Massive Scalar-Tensor Theories
We study polar quasinormal modes of relativistic stars in scalar-tensor theories, where we include a massive gravitational scalar field and employ the standard Brans-Dicke coupling function. For the potential of the scalar field we consider a simple mass

Scalar mesons and scalar gluonium
We investigate the mixing of scalar mesons (S*, ɛ) with gluonium in the context of a potential model. We calculate the masses of the scalars and the branching ratios to ππ,KK, ηη and ηη′. The model can accomodate the stateG(1.59) and explain its peculiar rates. We also investigate other possibilities for gluonium mass and branching ratios and find that

Scalar Extension of Bicoalgebroids [PDF]
After recalling the definition of a bicoalgebroid, we define comodules and modules over a bicoalgebroid. We construct the monoidal category of comodules, and define Yetter--Drinfel'd modules over a bicoalgebroid. It is proved that the Yetter--Drinfel'd category is monoidal and pre--braided just as in the case of bialgebroids, and is embedded into the ...

Organoids in pediatric cancer research
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Constant Scalar Curvature Metrics on Connected Sums
The Yamabe problem (proved in 1984) guarantees the existence of a metric of constant scalar curvature in each conformal class of Riemannian metrics on a compact manifold of dimension $n \geq 3$, which minimizes the total scalar curvature of this ...
