Singular unitary representations and indefinite harmonic theory
AbstractSquare-integrable harmonic spaces are defined and studied in a homogeneous indefinite metric setting. In the process, Dolbeault cohomologies are unitarized, and singlar unitary representations are obtained and studied.

Dual‐ligand‐modified perovskite fiber membranes achieve reversible, water‐triggered fluorescence switching with high environmental stability, enabling dynamic optical encryption and anti‐counterfeiting in moisture‐rich or water environments. ABSTRACT All‐inorganic lead halide perovskites are favored for next‐generation optoelectronic devices due to ...

Alternative Price Dynamics and Valuation of Flexible Strategies
ABSTRACT In this article, we study the optimal operational strategy of production projects. We investigate different underlying price models and determine the optimal barriers of transition to suspension, recovery, or irreversible abandonment of productive activity.

Optimal Homogeneous ℒp$$ {\boldsymbol{\mathcal{L}}}_{\boldsymbol{p}} $$‐Gain Controller
ABSTRACT Nonlinear ℋ∞$$ {\mathscr{H}}_{\infty } $$‐controllers are designed for arbitrarily weighted, continuous homogeneous systems with a focus on systems affine in the control input. Based on the homogeneous ℒp$$ {\mathcal{L}}_p $$‐norm, the input–output behavior is quantified in terms of the homogeneous ℒp$$ {\mathcal{L}}_p $$‐gain as a ...

The goal of this analysis is to compare constructions containing singular indefinite predicates (SIPs) of the type ‘Ion e un ţăran/Ion is a peasant’ with N of N constructions of the type ‘ţăranul de Ion’/peasant-the of Ion’ and explore the role that the ...

Solamargine induces acute myeloid leukemia differentiation through TLR8 activation
SM, a steroidal alkaloid from Solanum nigrum L. has shown anticancer effect on various kinds of human cancer cells, yet its effect on leukemia cells remains unclear. This study examines antileukemic activities of SM in AML cells. Results indicate SM inhibits growth and promotes apoptosis of AML cells.

Periodic Solutions of a Singular Equation With Indefinite Weight
AbstractMotivated by some relevant physical applications, we study the existence and uniqueness of T-periodic solutions for a second order differential equation with a piecewise constant singularity which changes sign. Other questions like the stability and robustness of the periodic solution are considered.

Abstract In Welsh, in certain tenses, unique forms of the verb for ‘be’ are used in positive clauses. These specialised forms of ‘be’ are incompatible with positive main‐clause declarative complementizers, despite their apparent featural compatibility. For most speakers, they are also blocked from if‐clauses; although, I report on data regarding their ...

Singular Sturm?Liouville problems with nonnegative and indefinite weights
This article is concerned with the oscillatory properties of the eigenfunctions of a class of singular Sturm-Liouville problems \(- (py')'+qy=\lambda wy\) on (a,b), where the weight function w vanishes on a subinterval of positive measure, or where the weight function w changes sign on (a,b).

A geometric representation of improper indefinite affine spheres with singularities [PDF]
Given a pair of planar curves, one can define its generalized area distance, a concept that generalizes the area distance of a single curve. In this paper, we show that the generalized area distance of a pair of planar curves is an improper indefinite affine spheres with singularities, and, reciprocally, every indefinite improper affine sphere in $\R^3$
