Population-Based Discrimination of Classical and Few-Photon Microwave Fields with a Flux-Tunable Transmon Qudit

Interactions between few-photon microwave fields and superconducting artificial atoms provide a method to study photon statistics and manipulate quantum states for photonic quantum information processing. Superconducting transmons couple to microwave fields through an anharmonic...

POPs Contamination of Aquatic Sediments of the Cerna River Watershed, Romania—Prevalence, Pollution Sources, and Ecological Risk Assessment

This study aims to evaluate the prevalence and pollution sources of polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and organochlorine pesticides (OCPs) in sediments of the Cerna River and its main tributaries, and to assess the associated ecological ri...

Guided elastic waves informed material modelling of soft incompressible media

Abstract Identifying a universal material constitutive law which describes the mechanical response of rubber-like solids for all deformation fields and achievable extensions, is an outstanding challenge. Here, we propose to exploit the propagation of elastic waves and demonstrate...

NKCC1 coordinates SPAK-PP1 signalling to regulate KCC2 membrane stability and seizure susceptibility.

Chloride homeostasis, and thereby the efficacy of chloride-permeable GABAA receptor signaling, depends on the dynamic balance between NKCC1 (Na+-K+-2Cl- cotransporter 1) and KCC2 (K+-Cl- cotransporter 2), which respectively mediate chloride influx and extrusion to tightly control...

A floating body with no preferred orientation: An experimental realization

We present a simple experimental realization of a two-dimensional floating body that can remain in equilibrium in any orientation. This system is based on a class of shapes known as Zindler curves, which possess the remarkable geometric property that all chords dividing their are...

SPEF1 mediates assembly of central pair microtubule complexes in cilia of Tetrahymena

SPEF1 is a conserved calponin-homology domain protein that decorates the seam of central pair microtubules in the distal segment of motile cilia. Here, we show that in the ciliate Tetrahymena, loss of SPEF1 disrupts the central pair throughout the middle segment, which comprises...

Frequency control of superconducting resonators using integrated interferometers

Predictable frequency trimming of superconducting resonators at liquid-helium temperatures requires a tuning element whose usable range remains well defined despite screening currents and hysteresis. Here, we realize flux-controlled λ/4 coplanar-waveguide resonators terminated by...

Phonon thermal Hall effect in quartz and its absence in silica

The observation of a misalignment between the applied heat flux and the measured temperature gradient in insulating solids induced by magnetic field has become a subject of experimental investigation, theoretical speculation, and unsettled controversy. To identify the origin of t...
