The ability to slow down light at the single-photon level has applications in quantum information processing and other quantum technologies. We demonstrate two methods, both using just a single artificial atom, enabling dynamic control over microwave light velocities in waveguide quantum electrodynamics (QED). Our methods are based on two distinct mechanisms harnessing the balance between radiative decay and nonradiative decoherence rates of a superconducting artificial atom in front of a mirror.

In this work, we report a facile strategy for synthesizing hydrophilic Gd(OH) sheets via a Gd-based interfacial precipitation reaction at the interface of organosilane-modified GdO nanoparticles and a cation exchange resin. This strategy, independent of the specific organosilane used, produces two-dimensional sheets with a distinct lamellar structure and excellent aqueous dispersibility. Characterization confirms the formation of Gd(OH) sheets with promising fluorescent and magnetic properties.

A novel P-type Buried Layer Diode-Triggered Silicon-Controlled Rectifier (PBL-DTSCR) with predicted good performance in electrostatic discharge (ESD) protection is proposed in this work. With P-type ESD implantations and silicide blocking layers applied to this novel structure, the efficiency of the diode triggering path is greatly improved, thus enhancing the discharge efficiency of the main path. Moreover, the parasitic SCR path is minimized by replacing the PNPN structure in conventional DTSCR to PNPNPN structure in PBL-DTSCR.

In this research, we have proposed a novel anomaly detection algorithm for processing hyperspectral images (HSIs), called the Graph Attention Network-Beta Wavelet Graph Neural Network-based Hyperspectral Anomaly Detection (GAN-BWGNN HAD). This algorithm treats each pixel as a node in a graph, where edges represent pixel correlations and node attributes correspond to spectral features. The algorithm integrates spatial and spectral information, utilizing graph neural networks to identify nonlinear relationships within the image, thereby enhancing anomaly detection precision.

Dynamic vision sensors (DVS) asynchronously encode the polarity of brightness changes with high temporal resolution and a wide dynamic range, making them ideal for capturing temporal information. Spiking neural networks (SNNs) are well-suited for handling such event streams due to their inherent temporal information processing capability. However, existing SNNs only transmit membrane potential across timesteps, neglecting spatial dependencies and failing to extract complex temporal features.

While antibody responses to influenza viruses have been extensively studied, the immunogenicity of influenza vaccines remains highly variable among individuals. Growing evidence suggests that the gut microbiota (GM) and associated metabolites play a critical yet understudied role in shaping host immunity, including responses to vaccines. However, the mechanistic pathways linking microbial communities, blood metabolites, and influenza vaccine-induced antibody production remain poorly understood.

Selective hydrogenation of biomass-derived furfural to furfuryl alcohol is fundamentally challenged by the dual adsorption of its reactive furan ring and carbonyl group on Pd catalysts, which drives nonselective pathways. To modulate the adsorption mode of furfural, we rationally incorporate carbon species onto Pd subnanoclusters encapsulated in a siliceous zeolite (Pd-C@S-1), achieving 98% selectivity for furfuryl alcohol at full furfural conversion, vastly outperforming the carbon-free Pd@S-1 (11.6% selectivity).

Low-turnover osteoporosis diagnosis urgently requires sensitive detection of low-abundance osteocalcin (OC), yet conventional methods remain constrained by insufficient sensitivity, cumbersome instrumentation, and laborious operations. We devise a CRISPR-driven pressure bioassay that synergistically integrates molecular recognition, enzymatic amplification, and signal transduction for dual-amplification-enhanced OC quantification. The system features an engineered "locked-to-activated" molecular switch, where target binding liberates CRISPR-activating DNA strands, initiating Cas14a-catalyzed cleavage of ssDNA tethers on FeO-ssDNA-Pt nanoassemblies.

Ambient-air, moisture-assisted annealing is widely used in fabricating perovskite solar cells (PSCs). However, the inherent sensitivity of perovskite intermediate-phase to moisture-due to fast and spontaneous intermolecular exchange reaction-requires strict control of ambient humidity and immediate thermal annealing treatment, raising manufacturing costs and causing fast nucleation of perovskite films. We report herein a self-buffered molecular migration strategy to slow down the intermolecular exchange reaction by introducing a n-butylammonium bromide shielding layer, which limits moisture diffusion into intermediate-phase film.

Engineering guest-responsive materials capable of controlled and precise sorption behavior and structural deformation in response to external stimuli is imperative for various applications. However, existing systems often exhibit complex, unpredictable dynamics, posing challenges for efficient control and utilization. Here, we design crystalline metal-peptide frameworks with tunable water-responsive (WR) dynamics by assembling glycine-threonine (Gly-Thr, GT) or glycine-serine (Gly-Ser, GS) peptides with zinc (Zn) ions, achieving either continuous or discrete threshold water-sorption-dependent phase transitions.

Exploring the interplay between topology and nonlinearity leads to an emerging field of nonlinear topological physics, which extends the study of fascinating properties of topological states to a regime where interactions between the particles cannot be neglected. For ultracold atomic systems, although many exotic topological states have been recently observed, the nonlinear effect remains elusive. Here, based on the laser-driven couplings of discrete atomic momentum states, we synthesize a topological trimer array, where the atomic interactions give rise to tunable nonlinearities.

The switching characteristics of GaN HEMT devices exhibit a very complex dynamic nonlinear behavior and multi-physics coupling characteristics, and traditional switching current models based on physical mechanisms have significant limitations. This article adopts a hybrid architecture of convolutional neural network and long short-term memory network (CNN-LSTM). In the 1D-CNN layer, the one-dimensional convolutional neural network can automatically learn and extract local transient features of time series data by sliding convolution operations on time series data through its convolution kernel, making these local transient features present a specific form in the local time window.

Electrohydrodynamic (EHD) printing offers mask-free, high-resolution deposition across a broad range of ink viscosities, yet combining void-free filling of high-aspect-ratio through-glass vias (TGVs) with ultrafine drop-on-demand (DOD) line printing on the same platform requires balancing conflicting requirements: for example, high field strengths to drive ink into deep and narrow vias; sufficiently high ink viscosity to prevent gravity-induced leakage; and stable meniscus dynamics to avoid satellite droplets and charge accumulation on the glass surface. By coupling electrostatic field analysis with transient level-set simulations, we establish a dimensionless regime map that delineates stable cone-jetting regime; these predictions are validated by high-speed imaging and surface profilometry. Operating within this window, the platform achieves complete, void-free filling of 200 µm × 1.

The development of an integrated circuit faces the challenge of the physical limit of Moore's Law. One of the most important "Beyond Moore" challenges is the scaling down of Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs) versus their increasing static power consumption. This is because, at room temperature, the thermal emission transportation mechanism will cause a physical limitation on subthreshold swing (), which is fundamentally limited to a minimum value of 60 mV/decade for MOSFETs, and accompanied by an increase in off-state leakage current with the process of scaling down.
