where a step function input is applied as a sudden change in pressure. The measured responses indicate that the system is nonlinear, as it fails the amplitude-scale invariance test. To describe the mass transport through a membrane made of porous materials, the Porous ...
Great work usually entails spending what would seem to most people an unreasonable amount of time on a problem. You can't think of this time as a cost, or it will seem too high. You have to find the work sufficiently engaging as it's happening. ...
Find the most general real-valued solution to the linear system of differential equations x' = (-18 -15 20 17) x. Find the most general real - valued solution to the linear system of differential equations vec{x} ' = [ - 2 1 \\ - 1 - 4 ] vec{x}. [ x_1(t) \...
In practice you don't have to worry much about the third criterion. Ambitious people are if anything already too conservative about it. So all you need to do is find something you have an aptitude for and great interest in.[1] That sounds straightforward, but it's often quite difficult. ...
Comparing to a generic two-state model, our models can distinguish class I from class II MHCs and correlate their structural parameters with the TCR/pMHC’s potency to trigger T cell activation. The models are tested by mutagenesis using an MHC and a TCR mutated to alter conformation changes....
In order to find the relation of the quantity [H] to the second law of thermodynamics in the form ∫dQ/T < 0, we shall interpret the system of mass points not, as previously, as a gas molecule, but rather as an entire body. But then, in the last couple of ...
You have to find the work sufficiently engaging as it’s happening. 伟大的工作通常需要在一个问题上花费大多数人认为多到不合理的时间。你不能把这个时间看作成本,否则它会显得太高。你必须从这项工作中感受到足够强的吸引力才行。 There may be some jobs where you have to work diligently for years ...
We find that the FX exposure of our sample firms before hedging is on average (median) hedged to about 90 (49) percent with predominantly short derivative instruments. Our findings reveal that approximately 20 percent of total firm exposure is managed using risk-increasing/risk-constant strategies...
Understanding the labor market participation shift associated with an aging population and the challenges of employees who provide care to old-age relatives is essential to ensure progress toward the Sustainable Development Goals. The current study focuses on the decision of employees who combine paid ...
Meanwhile, the AI model developers, who have taken in massive amounts of capital, need to find a business model that will repay all that investment. Times reporter Cade Metz provides an apocalyptic framing of the stakes and a binary view of the possible outcome. In his interview in The ...
