Nested sequent systems for modal logics are a relatively recent development, within the general area known as deep reasoning. The idea of deep reasoning is to create systems within which one operates at lower levels in formulas than just those involving the main connective or operator. Prefixed tableaus go back to 1972, and are modal tableau systems with extra machinery to represent accessibili...

Nested sequent systems for modal logics were introduced by Kai Brünnler, and have come to be seen as an attractive deep reasoning extension of familiar sequent calculi. In an earlier paper I showed there was a connection between modal nested sequents and modal prefixed tableaus. In this paper I extend the nested sequent machinery to intuitionistic logic, both standard and constant domain, and r...

We show that the principal attitude and inertial dynamics of a quadrotor aircraft can be decomposed into a cascade of three passive and one interior conic subsystem such that a proportional digital feedback loop can effectively be applied to each subsystem in a nested manner. This proportional feedback architecture includes one saturation block nested between the attitude and inertial control s...

In statistical term extraction systems the identification and selection of nested term candidates often presents a challenge. The paper presents an implementation and evaluation of C-value, a heuristic that ranks and/or discards nested terms according to their stability in the corpus. The method was tested for English and Slovene, for both the overall performance of the term extractor improved ...

Abstract The social–ecological systems (SES) framework (Ostrom 2009, Science. 325(5939):419–22) typologically decomposes SES characteristics into nested, tiered constituent variables. Yet, aligning the framework’s concepts of resource system (RS) and unit (RU) with realities individual case studies poses challenges if underlying is not a single RS, but mid to large-scale nested RS (NRS). Using ...

Counterdiabatic (CD) protocols enable fast driving of quantum states by invoking an auxiliary adiabatic gauge potential (AGP) that suppresses transitions to excited throughout the process. Usually, full spectrum original unassisted Hamiltonian is a prerequisite for constructing exact AGP, which implies CD are extremely difficult many-body systems. Here, we apply variational protocol recently pr...

This paper describes an execution time estimating model for nested transactions running on locally distributed database systems. At rst the model of nested transactions and the model of a locally distributed database system are established. The performance evaluation model of nested transactions is then built in three steps. The rst step describes a nondeterministic algorithm that evaluates the...
