Two studies explored whether adolescents can and will construct abstract visualizations to structure complex information. Experiment 1 showed that students can structure novel information with visualizations. Seventh-, 9th-, and 10th-grade students were directed to construct visualizations of complex transmission problems in biology (e.g., epidemiology). Two-thirds of the resulting visualizatio...

We develop a framework to calculate the density matrix of a pair of photons emitted in a decay cascade with partial " which path " ambiguity. We describe an appropriate entanglement distillation scheme which works also for certain random cascades. The qualitative features of the distilled entanglement are presented in a two dimensional " phase diagram ". The theory is applied to the quantum tom...

This tutorial discusses the different types of pulse oximeters including optical and reflective techniques and the design considerations taken when building high-end portable bedside monitors or mid and low-end battery-powered models. The discussion covers light absorption, sensor calibration, and details specifics within the transmit path leading to in-depth discovery of photodiode, interface,...

We show that for two quivers without oriented cycles related by a BGP reflection, the posets of their cluster tilting objects are related by a simple combinatorial construction, which we call a flip-flop. We deduce that the posets of cluster tilting objects of derived equivalent path algebras of quivers without oriented cycles are universally derived equivalent. In particular, all Cambrian latt...

We study cascades with partial which path ambiguity where entan-glement is distilled by spectral filtering. We develop a framework to calculate the amplitudes and phases of the density matrix. The results can be summarized in a two dimensional " phase diagram ". The theory is applied to the quantum tomography of the decay cascade of a biex-citon in a semiconductor quantum dot. The effect of inh...

It is constructed the Hasse diagram for the closure ordering on the sets of *congruence classes of 2× 2 matrices. In other words, it is constructed the directed graph whose vertices are 2× 2 canonical complex matrices for *congruence and there is a directed path from A to B if and only if A can be transformed by an arbitrarily small perturbation to a matrix that is *congruent to B.

We calculate quantum averages of Wilson loops (holonomies) in gauge theories on the Euclidean noncommutative plane, using a path-integral representation of the star-product. We show how the perturbative expansion emerges from a concise general formula and demonstrate its anomalous behavior at large parameter of noncommutativity for the simplest nonplanar diagram of genus 1. We discuss various U...

The algorithm described in this paper is the outcome Based on this model, we will consider a class of wellof an endeavor to answer the following question: Is it possible to find defined optimal path problems. A general procedure for procedures which would enable a computer to solve efficiently paths t c o p ... ~solving this class of problems will then be given in Secconnection problems inheren...

This paper presents a geometric based approach for multiple mobile robot motion coordination. All the robot paths being computed independently, we address the problem of coordinating the motion of the robots along their own path in such a way they do not collide each other. The proposed algorithm is based on a bounding box representation of the obstacles in the so-called coordination diagram. T...
