Q&A: A lateral thinker The winner of the 2007 Nobel Prize in Chemistry Gerhard Ertl ponders biology's big questions with Diane Wu. Comments & Opinion16 Oct 2013Nature Volume: 502, P: S53-S54 Natural moment-to-moment signal variability and stochastic facilitation ...
DNA is not only an essential object of study for biologists-it also raises very interesting questions for physicists. This paper discuss its nonlinear dynamics, its statistical mechanics, and one of the experiments that one can now perform at the level of a single molecule and which leads to ...
Many physics students have heard the saying, “For every action there is an equal and opposite re-action.” I was forced to memorize this statement in a middle-school science class, and was told it was called Newton’s Third Law. I’m sure I had no idea what it really meant. It sta...
9th grade physics multiple choice questions with answers has 239 MCQs for online physics learning. Physics MCQs are on dynamics, gravitation, kinematics, matter properties, physical quantities and measurement, thermal properties of matter, transfer of heat, turning effect of forces, work and energy....
Although there were no doubts concerning the self generation by the laminar Roberts-type or Ponomarenko-type flows that were used, these experiments have raised interesting questions about the influence of the turbulent fluctuations on the dynamo threshold and on the saturation level of the magnetic ...
The Drosophila system has also been largely unique in terms of its extensive use for addressing questions on the interface between population ecology and evolution. The most comprehensive experimental investigations of density-dependent selection and the evolution of competitive ability and density-specific...
(zoom). Ising interactions with the P1 system cause the NV to accumulate a phase,ϕ, during noise spectroscopy (Bloch sphere).c, NV and P1 level structure in the presence of a magnetic field,B, applied along the NV axis. We work within an effective spin 1/2 subspace of the NV ...
First, the results reveal that tutors frequently engaged in off-topic behaviors and direct instruction, regardless of students’ educational level. Second, tutors’ constructive questions and knowledge sharing and instruction were more associated with greater constructive expressions from students at higher ...
Metadynamics is a powerful method to accelerate molecular dynamics simulations, but its efficiency critically depends on the identification of collective variables that capture the slow modes of the process. Unfortunately, collective variables are usuall
