Distributed quantum sensing can provide quantum-enhanced sensitivity beyond the shot-noise limit (SNL) for spatially distributed parameters. To date, experiments have been mostly accomplished in laboratory environments without a real space separation sensors. In addition, post-selection is normally assumed to demonstrate advantage over SNL. Here, we field and show unconditional violation (witho...

introduction: the present study aimed to find an appropriate method to inform senior high school students to correctly select their academic field of study and their intentions. methods: this is a descriptive-analytic and cross-sectional study. a verified questionnaire was given to a total of 2600 students selected by stratified random sampling method (ten different colleges and entrance year f...

We focus on the problem of estimating the graph structure associated with a discrete Markov random field. We describe a method based on `1regularized logistic regression, in which the neighborhood of any given node is estimated by performing logistic regression subject to an `1-constraint. Our framework applies to the high-dimensional setting, in which both the number of nodes p and maximum nei...

Of all the steps in monitoring, choosing the correct indicators is arguably the most important. The challenge is obvious: among all the possible attributes of an ecosystem that can be measured, select a small number whose measurement will tell you something about all of the unmeasured attributes and processes. Even if a monitoring program is fully funded and implemented for many years, it will ...
