Research on Productivity Evaluation Method Based on Shale Gas Well Early Flow Stage Data
Since the accurate early gas well production regime is related to the production period and final productivity, it is crucial to make better use of early flow stage production data for gas well productivity evaluation. Absolute open flow potential (AOF) and estimated ultimate recovery (EUR) are essential parameters for evaluating the productivity of ...

Transient Dynamics of a Food Chain Model with Vigilance in the Biparameter Spaces
This article focuses on the asymptotic and transient behavior of a food chain model with vigilance in the biparameter spaces. Firstly, the local asymptotic stability conditions of the positive equilibrium point are obtained. Then, the transient dynamical behavior of the positive equilibrium point is analyzed based on eight parameters.

Weak l-sequential supercyclicity and weak quasistability
It is known that supercyclicity implies strong stability. It is not known whether weak l-sequential supercyclicity implies weak stability. In this paper we prove that weak l-sequential supercyclicity implies weak quasistability. Corollaries concerning the characterisation of (i) weakly l-sequentially supercyclic vectors that are not (strongly ...

Role of A‐Site Composition in Charge Transport in Lead Iodide Perovskites
The electronic properties of metal halide perovskites are measured with time‐resolved microwave conductivity, as a function of A‐site composition. It is found that a small percentage of Cs leads to a larger carrier mobility and lifetime and that compositions with a tolerance factor close to 0.9 generally show lower performance than those closer to 0.8 ...

Search for heavy quasistable leptons
Negative results of a search for heavy quasistable charged leptons at the IHEP accelerator are reported. For the selection of heavy leptons a system of scintillation and gas Cerenkov counters was used. The upper limit estimations of the differential cross sections for heavy lepton production in pN collisions at Ep = 70 GeV are, for example, d2 σ/dpω (p

Are there quasistable strange baryons with anticharm or antibeauty? [PDF]
In some models, exotic baryons with strangeness and anticharm or antibeauty should exist and even be stable against strong decay. We consider the stability of such possible exotic baryons, which in the constituent quark picture are called pentaquarks (each is composed of four quarks and an antiquark).

Quasistable charginos in ultraperipheral proton-proton collisions at the LHC [PDF]
Abstract We propose a model-independent approach for the search of charged long-lived particles produced in ultraperipheral collisions at the LHC. The main idea is to improve event reconstruction at ATLAS and CMS with the help of their forward detectors.

On the mass and width of the -boson and other relativistic quasistable particles [PDF]
The ambiguity in the definition for the mass and width of relativistic resonances is discussed, in particular for the case of the Z-boson. This ambiguity can be removed by requiring that a resonance's width $Γ$ (defined by a Breit-Wigner lineshape) and lifetime $τ$ (defined by the exponential law) always and exactly fulfill the relation $Γ= \hbar/τ ...
