An adaptive time integration procedure for automated extended-explicit/implicit hybrid analyses
This paper introduces a new explicit-implicit time-marching formulation, presenting a novel hybrid approach for wave propagation analysis. The...

Positive definiteness of Hadamard exponentials and Hadamard inverses
Let A be a positive semidefinite matrix. It is known that the Hadamard exponential of A is positive semidefinite; it is positive definite if and only...

A strong form of the quantitative Wulff inequality for crystalline norms
Quantitative stability for crystalline anisotropic perimeters, with control on the oscillation of the boundary with respect to the corresponding...

Does the Russia-Ukraine war cause exchange rate depreciation? Evidence from the rouble exchange rate
This paper aims to examine the impact of the Russian-Ukraine war on the USD/RUB rate. The outcome reveals that war has severe adverse consequences...

Production scheduling decision-making technology for multiple CNC machining centers with constraints on serviceable time
The tool’s life statistics module in CNC machining centers typically associates tool’s usage time with the program’s running duration, leading to the...

Weighted composition operators on variable exponent Lebesgue spaces
In this paper, we characterize the boundedness of weighted composition operators, induced by measurable transformations and complex-valued measurable...

Are the loans of state-owned banks politically motivated?
This paper investigates the relationship between annual disbursements of Brazil’s largest development bank, BNDES, and mayors political affiliation....

Pricing of shout option in uncertain financial market
The shout option allows the investors to make "shouts" to the seller throughout the option’s duration. The investors’ payoff is higher between the...

Envelopes in Banach spaces
We introduce the notion of isometric envelope of a subspace in a Banach space, establishing its connections with several key elements: (a) we explore...

Optimal timing and proportion in two stages learning investment
This article introduces a two-stage real option approach with a learning effect to examine the optimal timing and proportion of investment for a firm...

Clark Measures on Bounded Symmetric Domains
Given a bounded symmetric domain D , we study (positive) pluriharmonic functions on D and investigate a possible analogue of the family of Clark...

The life care annuity: enhancing product features and refining pricing methods
The state-of-the-art proposes life care annuities, that have been recently designed as variable annuity contracts with Long-Term Care payouts and...

Variational problems for the system of nonlinear Schrödinger equations with derivative nonlinearities
We consider the Cauchy problem of the system of nonlinear Schrödinger equations with derivative nonlinearlity. This system was introduced by Colin...

A Classical Requiem for Robert Solow
We prove an alternative and much simpler proof of the key results of the celebrated Solow growth model (Solow
1956 ), without the neo-classical... -
Exploring the agency cost of debt: risk, information flow, and CEO social ties
Contrary to the findings of prior research that focuses on private loans and bank debt, we find that greater CEO social capital is positively...

BV estimates on the transport density with Dirichlet region on the boundary
In this paper, we prove BV regularity on the transport density in the mass transport problem to the boundary in two dimensions under certain...
