A new experimental design eliminates the top source of clock uncertainty.
Optical lattice clocks (OLCs) are among the world’s best atomic clocks. Their largest source of uncertainty results from the…

Quantum ghost imaging of transparent birefringent patterns with phase singularities
Hyper-entanglement source and detection
A two-photon hyper-entanglement source consists of a BBO-HWP-BBO arrangement to produce EPR, polarisation hyper-entangled photons at the overlapping regions of down-converted conical emission profiles…

STRESS, an automated geometrical characterization of deformable particles for in vivo measurements of cell and tissue mechanical stresses
To explain and exemplify the STRESS analysis pipeline, we focus on the use of microdroplets to measure mechanical stresses in living tissues, as in this case measurements of stresses can be obtained solely from the droplet surface deformations…

Optical segmentation-based compressed readout of neuronal voltage dynamics
Implementation of the DeMOSAIC system
We implemented the DeMOSAIC system as an add-on to the detector port of an inverted epifluorescence microscope (Fig. 2a, Supplementary Fig. 1 and Supplementary Table 1). The sCMOS camera mounted in the…

Demonstration of a tunable non-Hermitian nonlinear microwave dimer
Figure 1 a illustrates the 3D microwave cavities used in our system, each with four ports featuring adjustable coupling rates, tunable (identical) resonance frequency, ωc, and fixed internal loss rates, κint. Figure 1b presents an exploded…

The electronic structure of 1/1 ZnMgHf and its consequences for the electronic transport of the quasicrystal
Structural relaxation
The structure after relaxation has a lattice constant equal to 14.3185 Å for B1 and 14.3004 Å for T1. This value is almost 5% greater than the experimentally determined value 13.6740 . With the GGA, the overestimation of…

Modeling the impact of intercellular signaling on dose metrics and therapeutic outcomes in spatially fractionated radiation therapy (SFRT) for lung cancer
Patient selection and contouring
From the patient population at Imam Khomeini Hospital’s Cancer Institute, a lung cancer patient with a GTV of 875.310 cm3 was retrospectively selected. This study was conducted using anonymized CT scan images,…
