EquationProblem : Solve for: x eq1: exp((-exp((-(x(1) + x(2))) == (x(2) .* (1 + x(1).^2)) eq2: ((x(1) .* cos(x(2))) + (x(2) .* sin(x(1))) == 0.5 Solve the problem starting from the point[0,0]. For the problem-based approach, specify the initial ...
for the dilation onwith ratio. Theorem 1.1 Consider two linksand a pseudo-Seifert surfaceconnectingandin time. Then, there is a global smooth solutionu(x,t) to the Gross–Pitaevskii equation on, tending to 1 at infinity, which realizes the vortex reconnection pattern described byup to a diff...
To derive a relationship between vm(x, t) and v(x, t), let us start with the expression of v(x, t) based on the volume-averaged velocity field $$ {\varvec{v}} = \delta \left( {{\varvec{x}},{ }t} \right){\varvec{v}}_{{\text{S}}} + {\varvec{v}}_{{\text{f}...
遍历系统文件、清除/var/log/lastlog记录、获取系统账户密码信息。 连接Google判断网络连通状态。 连接远程服务器,并根据远程控制指令进行不同的操作。 样本中同样存在多处信息加密算法和网络通讯加密算法。 样本会利用一个链接文件启动自身,proc/%d/exe文件指向样本自身文件。
variable N 称作是stopping time for \{ \mathrm{X}_{1}, \mathrm{X}_{2}, \ldots, \mathrm{X}_{n}, \ldots\} ,如果 N=n 这一事件发生只依赖与 \{X_1,X_2,\cdots X_n\} 而与X_{n+1},X_{n+2}\cdots 无关。 例子 hitting time(第一次到达某一个或者某几个变量的时间)都是stop...
We can nevertheless try to use the ansatz (12) also in the active case, since it might still be a good approximation for small activities. Integrating the microscopic dynamics of P1 (Eq. (64) from the Methods) over p using Eq. (12) (with ρ replaced by ϱ) yields $$\dot{\varrho...
2.1 ROMS 4D-Var The model implemented in this study is the Regional Ocean Modeling System (ROMS). ROMS is a hydrostatic primitive equations model with orthogonal curvilinear coordinates in the horizontal and terrain following coordinates in the vertical making it ideally suited for modeling coastal an...
which is well defined for (\varepsilon , h) \in [-\varepsilon _0,\varepsilon _0] \times \{h\in H^1_{rad}, \Vert h\Vert _{L^2(\mathbb {R}^n)}=1\} and \varepsilon _0>0 small. Then \begin{aligned} K(\varepsilon ,h) = \frac{D(|Q+\varepsilon h|^p,|Q+\varepsi...
