Expressiveness and Closure Properties for Quantitative Languages [PDF]

Logical Methods in Computer Science, 2010
Weighted automata are nondeterministic automata with numerical weights on transitions. They can define quantitative languages~$L$ that assign to each word~$w$ a real number~$L(w)$.

How fast can vanadium dioxide neuron-mimicking devices oscillate? Physical mechanisms limiting the frequency of vanadium dioxide oscillators

Neuromorphic Computing and Engineering, 2023
The frequency of vanadium dioxide (VO _2 ) oscillators is a fundamental figure of merit for the realization of neuromorphic circuits called oscillatory neural networks (ONNs) since the high frequency of oscillators ensures low-power consuming, real-time ...

Asymptotic critical behavior of holographic superconductor phase transition — the spectrum of excited states becomes continuous at T = 0

Journal of High Energy Physics, 2022
Within the framework of AdS/CFT duality, excited states of the conformal field living at the global AdS boundary of a four-dimensional spacetime Einstein gravity are investigated analytically in the probe limit where the field equations are linearized ...

Lithium-ion electrolytic substrates for sub-1V high-performance transition metal dichalcogenide transistors and amplifiers

Nature Communications, 2020
Electrostatic gating of 2D transistors with ionic liquids presents intrinsic limitations. Here, the authors demonstrate n-type MoS2 and p-type WSe2 transistors on a lithium-ion solid electrolyte substrate, displaying sub-threshold values approaching the ...

Compliance between Food and Feed Safety: Eight-Year Survey (2013–2021) of Aflatoxin M1 in Raw Milk and Aflatoxin B1 in Feed in Northern Italy

Toxins, 2023
Aflatoxins (AFs) are fungal metabolites that are found in feed and food. When ruminants eat feed contaminated with aflatoxin B1 (AFB1), it is metabolised and aflatoxin M1 (AFM1) is excreted in the milk. Aflatoxins can result in hepatotoxic, carcinogenic,

Comparison of automatic and visual methods used for image segmentation in Endodontics: a microCT study

Journal of Applied Oral Science
To calculate root canal volume and surface area in microCT images, an image segmentation by selecting threshold values is required, which can be determined by visual or automatic methods. Visual determination is influenced by the operator's visual acuity,
