Many methods have been developed by scientists to find solutions for nonlinear problems. In this paper, the general structure of modified trial equation method (MTEM) is introduced, and MTEM used some exact (2+1)-dimensional Broer-Kaup-Kupershmidt (BKK), Kolmogorov-Petrovskii-Piskunov (KPP) equations. Firstly, an algebraic system obtained reducing partial differential (NLPDE) ordinary under tra...

The method of time domain electromagnetic (TDEM) migration is used for fast imaging of subsurface geoelectrical structures. The computation of the migration field is based on downward extrapolation of the observed field in reverse time. In this paper we examine an effective method of EM migration based on the operator of an integral transformation in the spatial-temporal domain. The migration c...

The preparation, characterization, and study of small struct ures are problems of major current activity. 1,2 Many of the physical properties of microstructures such as small particles, muItilayers, or supedattices are strongly connected to their morphology. Structural characterization is mostly accomplished with the use of diffraction (x ray, neutron or electron) and imaging [transmission (TEM...

In this research, the modified trial equation method (MTEM) is considered in order to find some exact solutions of van der Waals model. addition, finding solution model can be used nonlinear problems. Thus, wave for various situations are obtained. Also, three and two dimensional graphs were found with help Mathematica9 analyze physical behavior obtained solutions.

the data sizes in fully 3D PET imaging are very iterative image reconstruction algorithms must tge in very few iterations to be useful. One nprove the convergence rate of the conjugate:nt (CG) algorithm by incorporating precondig operators that approximate the inverse of the Ln of the objective function. If the 3D cylindriET geometry were not truncated at the ends, ;he Hessian of the penalized ...

Machine Translation Evaluation Metrics (MTEMs) are the central core of Machine Translation (MT) engines as they are developed based on frequent evaluation. Although MTEMs are widespread today, their validity and quality for many languages is still under question. The aim of this research study was to examine the validity and assess the quality of MTEMs from Lexical Similarity set on machine tra...

When we reason about change over time, causation provides an implicit preference: we prefer sequences of situations in which one situation leads causally to the next, rather than sequences in which one situation follows another at random and without causal connections. In this paper, we explore the problem of temporal reasoning—reasoning about change over time—and the crucial role that causatio...

Introduction: Patients (pts) with diffuse large B-cell lymphoma (DLBCL) who relapse after stem cell transplant or chimeric antigen receptor therapy are refractory to second-line have poor prognosis and few treatment options (Chow et al., 2019). For these pts, long-term disease control manageable toxicity is the goal. Loncastuximab tesirine (loncastuximab tesirine-lpyl; Lonca), an anti-CD19 anti...
