Green Innovation and Firm Efficiency: The Role of Institutional Quality in Italian High‐Tech Manufacturing Sectors

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The aim of this research is to verify whether institutional quality affects the relationship between green innovation and firm efficiency within the high‐tech manufacturing sectors. To estimate jointly the parameters of a stochastic frontier and the coefficients of a model explaining technical inefficiency, we employed the one‐step estimation ...

Partially Ordered Two-way B\"uchi Automata

open access: yes, 2011
We introduce partially ordered two-way B\"uchi automata and characterize their expressive power in terms of fragments of first-order logic FO[

Unambiguous Separators for Tropical Tree Automata [PDF]

open access: yes, 2019
In this paper we show that given a max-plus automaton (over trees, and with real weights) computing a function f and a min-plus automaton (similar) computing a function g such that f ?

Lactuca sativa L. losses and wastes as a source of biobased ingredients

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND The growing global population and increasing consumer focus on healthy eating challenge the agricultural sector to ensure both sustainable food production and safety. Lettuce (Lactuca sativa Mill.), the most cultivated leafy vegetable worldwide, can lose up to 40% of its weight during processing.

What is known about the Value 1 Problem for Probabilistic Automata? [PDF]

open access: yes, 2014
The value 1 problem is a decision problem for probabilistic automata over finite words: are there words accepted by the automaton with arbitrarily high probability?

Finitary languages

open access: yes, 2011
The class of omega-regular languages provides a robust specification language in verification. Every omega-regular condition can be decomposed into a safety part and a liveness part.

A Modal Logic for Subject-Oriented Spatial Reasoning [PDF]

open access: yes, 2019
We present a modal logic for representing and reasoning about space seen from the subject\u27s perspective. The language of our logic comprises modal operators for the relations "in front", "behind", "to the left", and "to the right" of the subject ...

Sleep and cardiac autonomic modulation in older adults: Insights from an at‐home study with auditory deep sleep stimulation

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary The autonomic nervous system regulates cardiovascular activity during sleep, likely impacting cardiovascular health. Aging, a primary cardiovascular risk factor, is associated with cardiac autonomic disbalance and diminished sleep slow waves. Therefore, slow waves may be linked to aging, autonomic activity and cardiovascular health. However, it

Optimal Satisfiability Checking for Arithmetic $\mu$-Calculi

open access: yes, 2019
The coalgebraic $\mu$-calculus provides a generic semantic framework for fixpoint logics with branching types beyond the standard relational setup, e.g. probabilistic, weighted, or game-based.

Emptiness Of Alternating Tree Automata Using Games With Imperfect Information [PDF]

open access: yes, 2013
We consider the emptiness problem for alternating tree automata, with two acceptance semantics: classical (all branches are accepted) and qualitative (almost all branches are accepted).
