Quantum speed limit for non-Markovian dynamics [PDF]

open access: yesPhysical Review Letters, 2013
We derive a Margolus-Levitin type bound on the minimal evolution time of an arbitrarily driven open quantum system. We express this quantum speed limit time in terms of the operator norm of the nonunitary generator of the dynamics. We apply these results

Ribozyme speed limits [PDF]

open access: yesRNA, 2003
The speed at which RNA molecules decompose is a critical determinant of many biological processes, including those directly involved in the storage and expression of genetic information. One mechanism for RNA cleavage involves internal phosphoester transfer, wherein the 2′-oxygen atom carries out an SN2-like nucleophilic attack on the adjacent ...

Vehicle speed control using road bumps [PDF]

open access: yesTransport, 2004
Road bumps play a crucial role in enforcing speed limits, thereby preventing overspeeding of vehicles. It significantly contributes to the overall road safety objective through the prevention of accidents that lead to deaths of pedestrians and damage of ...

Quantum speed limit for complex dynamics

open access: yesnpj Quantum Information, 2023
Quantum speed limit focuses on the minimum time scale for a fixed mission and hence is important in quantum information where fast dynamics is usually beneficial. Most existing tools for the depiction of quantum speed limit are the lower-bound-type tools,

Research on Length Design and Dynamic Usage Strategy of Railway Successive Routes

open access: yesIEEE Access, 2021
As a measure to ensure the safety of trains in Chinese Railways, the successive route can prevent accidents such as exceeding the planned parking point and rear-ending the train in the front during the process of entering the station.

The innovative design of automatic speed limiter device for trucks and buses based on road location analysis

open access: yesJurnal Ilmiah SINERGI, 2022
The increasing number of vehicles every year has led to the rising potential of vehicle accidents. In 2015, there were 556 fatalities from 6,231 accident cases occurred in Jakarta, through regulation of the Minister of Transportation Republic Indonesia ...

Finite-time adiabatic processes: derivation and speed limit [PDF]

open access: yes, 2020
Obtaining adiabatic processes that connect equilibrium states in a given time represents a challenge for mesoscopic systems. In this paper, we explicitly show how to build these finite-time adiabatic processes for an overdamped Brownian particle in an ...

Assessing the impact of high environmental temperatures on the frequency and structural characteristics of violations of traffic rules

open access: yesИнтеллект. Инновации. Инвестиции, 2022
In the hot season, there is a positive relationship between the number of accidents per thousand registered vehicles and air temperature, due to the fact that high temperatures and solar activity can have a significant negative impact on the condition of

Precision thermometry and the quantum speed limit [PDF]

open access: yes, 2018
We assess precision thermometry for an arbitrary single quantum system. For a $d$-dimensional harmonic system we show that the gap sets a single temperature that can be optimally estimated.
