Queueing-inventory: analytical and simulation modeling and classical and retrial queues and inventory
This is the PREFACE to the Special Issue “Queueing-inventory: analytical and simulation modeling and classical and retrial queues and inventory”. The...

On the Connected Blocks Polytope
In this paper, we study the connected blocks polytope, which, apart from its own merits, can be seen as the generalization of certain connectivity...

Exploring servitization in the supply chain: a review of current research via bibliometric analysis and future study prospects
Servitization, an emerging strategy that combines product and service offerings, is gaining traction among manufacturing firms seeking a competitive...

Lattice-Based Polynomial Commitments: Towards Asymptotic and Concrete Efficiency
Polynomial commitments schemes are a powerful tool that enables one party to commit to a polynomial p of degree d , and prove that the committed...

Nonpositively Curved Surfaces are Loewner
We show that every closed nonpositively curved surface satisfies Loewner’s systolic inequality. The proof relies on a combination of the Gauss–Bonnet...

Structural iterative rounding for generalized k-median problems
This paper considers approximation algorithms for generalized k -median problems. These problems can be informally described as k -median with a...

Boundary Rigidity, and Non-Rigidity, of Projective Structures
We investigate the property of boundary rigidity for the projective structures associated to torsion-free affine connections on connected smooth...

The Price of Active Security in Cryptographic Protocols
We construct the first actively-secure Multi-Party Computation (MPC) protocols with an arbitrary number of parties in the dishonest majority setting,...

Covering Array on the Cartesian Product of Hypergraphs
Covering array (CA) on a hypergraph H is a combinatorial object used in interaction testing of a complex system modeled as H . Given a t -uniform...

Octonionic Calabi–Yau Theorem
On a certain class of 16-dimensional manifolds a new class of Riemannian metrics, called octonionic Kähler, is introduced and studied. It is an...

Free disposal hull models of multicomponent technologies
Free disposal hull (FDH) is a nonparametric model of production technology based on the single assumption of free disposability of all inputs and...
