We show that the recently introduced ModMax theory of electrodynamics and its Born-Infeld-like generalization are related by a flow equation driven quadratic combination stress-energy tensors. The operator associated to this is $4d$ analogue $T\bar{T}$ deformation in two dimensions. This result generalizes observation ordinary Born-Infeld Lagrangian free Maxwell current-squared flow. As case, w...
Source of statistical noises in the Monte Carlo sampling techniques for coherently scattered photons
Detailed comparisons of the predictions of the Relativistic Form Factors (RFFs) and Modified Form Factors (MFFs) and their advantages and shortcomings in calculating elastic scattering cross sections can be found in the literature. However, the issues related to their implementation in the Monte Carlo (MC) sampling for coherently scattered photons is still under discussion. Secondly, the linear...
مقدمه: با نوشتن یک کد خاص براساس تکنیک grid search طیف انرژی عناصر بررسی شده است. این روش را می توان برای بررسی طیف های اتمی، مولکولی و هسته ای ، پالس های لیزر و مطالعه طیف هایی که از برهمکنش لیزر با سلول ها و اجزاء مختلف انسانی به دست می آید، به کار برد. طیف میکرورامان لنزهای چشمی برازش شده توسط de.mul و طیف زمانی برازش شده با نرم افزار gnuplot یک تک مولکول که با لیزری با طول موج 585 نانومتر ب...
Some twenty-five years ago Balitsky, Fadin, Kuraev and Lipatov (BFKL) set out to determine the high-energy behaviour of the scattering of hadronic objects within perturbative QCD. They found terms going as (αs ln s) n, where s is the squared centre-of-mass energy. Since ln s is large it can compensate the smallness of ᾱs and thus it was necessary to sum this whole series of leading logarithmic ...
Objective of our study was to define a diagnostic-therapeutic pathway for proper treatment of not-palpable testicular masses, that may be benign in 38% of cases. Since the intraoperative diagnosis is difficult to reach in particular in small lesion (< 8 mm) and the risk of tissue loss in frozen section analysis occurs frequently, we propose a diagnostic flow chart for the best management of ...
