We present an open-source computer program written in Python language for quantum measurement and related issues. In our program, quantum states and operators, including quantum gates, can be developed into a quantum-object function represented by a matrix. Build into the program are several measurement schemes, including von Neumann measurement and weak measurement. Various numerical simulation methods

SModelS is an automatized tool enabling the fast interpretation of simplified model results from the LHC within any model of new physics respecting a Z2 symmetry. We here present a new version of SModelS, which can use the full likelihoods now provided by ATLAS in the form of pyhf JSON files. This much improves the statistical evaluation and therefore also the limit setting on new physics scenarios

EGS (Enhanced Geothermal System) is a potential way to utilize geothermal energy efficiently. In present work, a three-dimensional physical model, a single fracture with undulated surface morphology in hot dry rock is constructed. Supercritical CO2 is used as working fluid, and its convection heat transfer characteristics in fracture is numerically investigated. The influence of flow rate, inlet temperature

Gaseous pollutants transport inside liquid micro-cylinders with internal circulations in an equilateral triangular configuration is simulated to study the effects of varied gap-ratio (1 ≤ G/R ≤ 4), Reynolds (Re) number (30 ≤ Re ≤ 160) and incident angle (α = 0°, 30° and 60°) on the absorption in a uniform gaseous stream. The shear stress fluctuates with spatial position on the interface due to unsteady

Herein, we propose a monolithic reflector-integrated waveguide photodetector with optical isolation between photosensitive mesa and N-contact mesa for achieving a high efficiency bandwidth product. In the proposed photodetector, the photosensitive mesa is optically isolated but electrically connected with the N-contact mesa; this is achieved by etching a portion of the core layer to form a groove on

Multi-source image matching is a challenging task due to the presence of image distortion, as well as significant intensity changes between image pairs in corresponding regions. In addition, the influences of variant scales and multiplicative noises will also have an adverse effect on the matching accuracy. In this paper, a combination of feature descriptor called “histogram of angle and maximal edge

In this report, a wide range of spectroscopic studies was undertaken on the astrophysical significant deuterated methanol (CD3OD) species. In the submillimeter wave(SMMW) wave a large number of very accurate spectral line positions in the useful range of 130-750GHz have been reported. The actual spectral recording of the spectrum in the range 325-344GHz with a high signal to noise ratio (S/N) have

Post-buckled structures are prone to snap-through instabilities when external loading causes the structure to lose local stability and jump to a remote equilibrium. However, using piezoelectric actuation, structures can undergo entirely stable transitions between remote equilibria, thereby avoiding snap-through. This paper investigates the linearized vibrational properties of post-buckled beams along

Vortex-induced vibration (VIV) is the result of the interaction between the airfoil vibration and vortex shedding, and it frequently achieves the peak vibration amplitude in the lock-in region. Therefore, distinguishing the effect of the two disturbances in the lock-in region is important for understanding VIV. In this study, the NACA 0012 airfoil was investigated at high angles of attack; thus, the

Substructuring approaches have been extensively used since long time to predict the vibroacoustic behaviour of built-up mechanical systems. In the frequency domain, these methods build on the dynamic characterisation of the subsystems via frequency response functions at the coupling interfaces. Intensively used for subsystems connected by points, dynamic substructuring still constitutes an open area

Characteristic multipliers (CMs) describe the behavior, such as stability, of a dynamical system near a limit cycle. While existing methods are available to estimate CMs from time series measurements of the system’s state, practical challenges such as measurement noise, limited time series length, and repeated CMs can substantially reduce their accuracy. This paper describes a number of simple-to-implement

An approximation method for estimating the modal loss factors of a coupled structural-acoustical problem is proposed using the finite element method. This method provides a practical approach in terms of computational time and memory consumption. To validate our approach, we consider a coupled system in which the acoustical region is enclosed by a structural region, and both structural and acoustical

In this study, Au–4H-n-SiC metal–semiconductor (MS) and Au–Al2O3–4H-n-SiC metal–insulator–semiconductor (MIS) devices were fabricated to examine the effects on the performance of electronic devices of interfacial insulating materials. In order to determine the dielectric properties, capacitance/conductance–voltage (C/G–V) measurements were realized in a wide range of voltages (−3.0 V)–(11.0 V). Current–voltage

The influence maximization problem in social networks aims to select a subset of most influential nodes, denoted as seed set, to maximize the influence diffusion of the seed nodes. The majority of existing works on this problem would ignite all the seed nodes simultaneously at the beginning of the diffusion process and let the influence diffuses passively in the network. However, it cannot depict the

A flux reconstruction approach is implemented in the spectral difference (SD) framework, which we refer to it as discontinuous spectral element method (DSEM), to improve the accuracy and stability of numerical simulations. A new class of correction functions is developed based on a weighted orthogonality condition, which leads to the introduction of Jacobi correction functions. Jacobi correction functions

Estimating oil and gas production from assets is essential to carry oil recovery processes. From the many techniques and tools used for such a task, the compositional simulation model is important for miscible displacement and problems with complex phase behavior. In this model, the fluid flow in porous media is described by a set of conservation equations. The solution of these problems involves spatial

The numerical scheme is constructed based on a recently developed energetic variational formulation, in which the reaction part is reformulated in terms of reaction trajectories. The fact that

We study the first-passage problem for a process governed by a stochastic differential equation (SDE) driven simultaneously by both parametric Gaussian and Lévy white noises. We extend the path integral (PI) method to solve the SDE with this combined noise input and the corresponding fractional Fokker-Planck-Kolmogorov equations. Then, the PI solutions are modified to analyze the first-passage problem

We introduce new intersection-distribution-based remapping tools for indirect staggered arbitrary Lagrangian-Eulerian (ALE) simulations of multi-material shock hydrodynamics on arbitrary meshes. In addition to conserving momentum and total energy, the three-stage remapper proposed in this work preserves non-negativity of the internal energy. At the first stage, we construct slope-limited piecewise-linear

Phase retrieval (PR)‐based phase‐contrast CT (PCCT) is an imaging method for retrieving and reconstructing the phase shifts within an object. This study aimed to evaluate the feasibility of PR‐based PCCT with microbubble contrast agent for vascular imaging.

The modulation transfer function (MTF) is widely used as an objective metric of spatial resolution of medical imaging systems. Despite advances in capability for 3D isotropic spatial resolution in CT and cone‐beam CT (CBCT), MTF evaluation for such systems is typically reported only in the axial plane, and practical methodology for assessment of fully 3D spatial resolution characteristics is lacking

The conventional correction techniques for gamma spectra usually use approximate algorithms, the calculation procedures are tedious and complicated, the obtained corrected spectra are usually the channel domain spectra even if they are calibrated by energy. Moreover, the spectra are still dependent upon system parameters themselves such as the gain of amplifier and the offset of ADC etc. In this paper

Magnetic wave perturbations are observed in the solar wind and in the vicinity of Earth's bow shock. For such environments, recent work on magnetic pumping with electrons trapped in the magnetic perturbations has demonstrated the possibility of efficient energization of superthermal electrons. Here we also analyse the energization of such energetic electrons for which the transit time through the system

In the physicists' perspective, epithelial tissues constitute an exotic type of active matter with non-linear properties reminiscent of amorphous materials. In the context of a circular proliferating epithelium, modeled by the quasistatic vertex model, we identify novel discrete tissue scale rearrangements, i.e. cellular flow avalanches, which are a form of collective cell movement. During the avalanches
