Radial expansion

We measure the radius of the spherical cell colony (Fig. 1e and Supplementary Movie 1) by computing the particle number density as a function of distance from the center and setting a threshold based on a reference bulk density…

Results in two dimensions

Figure 1 illustrates the essence of our flow-field reconstruction by considering a 2D example of a droplet coalescence in the 2D CHNS system. We begin with a DNS image of the CHNS concentration field ϕ, at a given time,…

Steering test

Here we consider the bipartite qubit scenario, in a steering test, the examiner (Bob) first receives a set of quantum states (called assemblage), and then selects a list of questions from a questionary to send them to the examinee…

Governing equations for continuous and dispersed phases

The fluid flow within the respiratory system is governed by the Navier-Stokes equations, which describe key parameters such as velocity, pressure, density, and viscosity of air as it…

Theoretical prediction

In order to focus on the research scope, we fixed the Zr:N ratio at 1:1, which means that the form of Zr-N-H ternary hydride is ZrNH_x. Then, we used particle swarm optimization algorithm to search for the low-enthalpy…

X-ray diffraction study

The XRD technique has been nominated as a powerful tool in the field of material science and engineering. It relies on the capacity of crystals to diffract X-rays in a distinctive way, enabling an accurate examination of…

In-sensor dynamic compressing and computing

Figure 1a illustrates the implementation of in-sensor compressing and downstream computing based on our 2D PPMS. The PPMS integrated incoming 2D frames modulated by electrical masks, effectively…

To examine our argument, we begin by analyzing the working mechanism for a semiconductor phototransistor/diode. This kind of device is the most commonly used photodetector, It mainly contains a semiconductor (e.g., p-n or p-i-n) junction⁷ (It…

The schematics of the device used in the experiment is shown in Fig. 1a. Electrostatic gates deplete the two-dimensional hole gas beneath, creating a double quantum dot (DQD) on the bottom part of the device to be operated as a qubit. A single…
