We study adiabatic reverse annealing (ARA) in an open system. In the closed system (unitary) setting, this protocol allows avoidance of first-order quantum phase transitions selected models, resulting exponential speedup compared with standard annealing, provided that initial state algorithm is close Hamming distance to target one. Here, we show decoherence can significantly modify conclusion: ...

In this paper, nitrogen diffusion is investigated in single-crystalline austenitic stainless steel during modified layer formation and thermal annealing. A generalized system of equations derived within a thermodynamic framework from Fick’s laws, which describe flux under multiple driving forces, including concentration gradient the hydrostatic stress. Trapping detrapping phenomena are consider...

Simulated quantum annealing based on the path-integral Monte Carlo is one of most common tools to simulate classical hardware. Nevertheless, it in principle highly non-trivial whether or not this algorithm can correctly reproduce dynamics annealing, particularly diabatic regime. We study problem numerically through generalized Kibble-Zurek mechanism defect distribution simplest ferromagnetic on...

With the formation of the competitive electricity markets in the world, optimization of bidding strategies has become one of the main discussions in studies related to market designing. Market design is challenged by multiple objectives that need to be satisfied. The solution of those multi-objective problems is searched often over the combined strategy space, and thus requires the simultaneous...

INTRODUCTION We aimed to compare apical canal transportation of extracted teeth and two types of simulated resin blocks. MATERIALS AND METHODS Mesiobuccal root of extracted maxillary molars, high hardness simulated resin blocks (Knoop hardness=40) and low hardness simulated resin blocks (Knoop hardness=22) were prepared with K-files using step-back technique (n=15 canals in each group). Doubl...

in the present work the recrystallization behavior of deep drawing grade al-killed low carbon steel sheets produced by mobarakeh steel plant (msp) has been studied. salt bath isothermal annealing has been applied to cold rolled samples and the resulted microstrucrures have been compared with the microstructure obtained from the box annealing process in msp. it is found that at 635 and 700ºc the...

This paper describes a knowledge-based simulation system for a glass annealing process. The long ovens, known as lehrs, in which annealing takes place are not well understood by their operators. In fact, only a few experts can predict the effects of a change in the lehr controls. Attempts to simulate the behavior of the lehr using conventional methods have not been successful due to the size an...

We propose a general-purpose method for finding high-quality solutions to hard optimization problems, inspired by self-organizing processes often found in nature. The method, called Extremal Optimization, successively eliminates extremely undesirable components of sub-optimal solutions. Drawing upon models used to simulate far-from-equilibrium dynamics, it complements approximation methods insp...

This paper considers the identical parallel machine scheduling problem to minimize the makespan with controllable processing times, in which the processing times are linear decreasing functions of the consumed resource. The total resource consumption is limited. This problem is NP-hard even if the total resource consumption equals to zero. Two kinds of machines, critical machine and non-critica...

Several real-time PCR (rtPCR) quantification techniques are currently used to determine the expression levels of individual genes from rtPCR data in the form of fluorescence intensities. In most of these quantification techniques, it is assumed that the efficiency of rtPCR is constant. Our analysis of rtPCR data shows, however, that even during the exponential phase of rtPCR, the efficiency of ...
