At this point, we require an explicit form of the characteristics. First, consider the solution to the ODE ȳξ(ξ, η) = 1. Integrating with respect to ξ, we find ȳ = ξ + φ(η). Applying the initial value on Γ, where y0(η) = 0 and ξ = 0, we find φ(η) = 0. Next, consider the solution to the ODE x̄ξ(ξ, η) = η . Integrating with respect to ξ, we find x̄ = ξη + ψ(η). Using the initial value on Γ, where x...
Problem 1 Find u(x, y) satisfying u x + u y = u 2 , u(x, −x) = x, −∞ ≤ x ≤ ∞ Sketch the characteristic curves and show the domain of validity of the solution in the (x, y)-plane. In this problem we will examine the solution to a nonhomogeneous first-order PDE with constant coefficients. In order to solve this problem we can follow a typical approach: (1) find an explicit form for the characteri...
For each of the following functions u 0 (x), construct solutions to the initial value problem (1 + ku)u x + u y = 0, y ≥ 0 u(x, 0) = u 0 (x) is a given function for −∞ ≤ x ≤ ∞ Draw the characteristics in the (x, y)-plane. If you find the wave-breaking phenomenon arising, determine the time and place of the initial break appearance and find a solution containing a shockwave. For this first probl...
BACKGROUND MicroRNA-202 (miR-202) has been reported to be aberrantly regulated in several cancers. The aim of this study is to explore the functional role of miR-202 in EAC tumor growth. MATERIAL AND METHODS miR-202 expression was detected by qRT-PCR. TargetScan and luciferase reporter assay were used to elucidate the candidate target gene of miR-202. The FOXR2 protein level was assessed by W...
The human cervical cancer (CC) acts as the most common one of women tumors. However, the pathological changes and molecular alterations of CC are not clear. It has been reported that miR-202 takes part in the development and progression of different tumors. The present study aims to detect the expression of miR-202 in 100 cases of CC tissues and cells, and then we continued to investigate the p...
The magnetic moments and isotope shifts of the neutron-deficient francium isotopes (202-205)Fr were measured at ISOLDE-CERN with use of collinear resonance ionization spectroscopy. A production-to-detection efficiency of 1% was measured for (202)Fr. The background from nonresonant and collisional ionization was maintained below one ion in 10(5) beam particles. Through a comparison of the measur...
