Quantum Circuit Architecture Search on a Superconducting Processor.

Variational quantum algorithms (VQAs) have shown strong evidence to gain provable computational advantages in diverse fields such as finance, machine learning, and chemistry. However, the heuristic ansatz exploited in modern VQAs is incapable of balancing the trade-off between expressivity and trainability, which may lead to degraded performance when executed on noisy intermediate-scale quantum (NISQ) machines. To address this issue, here, we demonstrate the first proof-of-principle experiment of applying an efficient automatic ansatz design technique, i.

Formation and Magnetic Properties of Transition Metal Atomic Chains on Monolayer MoS Grain Boundaries: A First-Principles Study.

Magnetic one-dimensional nanostructures show great potential in spintronics and can be used as basic building blocks for magnetic materials and devices with multiple functions. In this study, transition group atomic chains (V, Cr, Mn, Fe, Co, and Ni) are introduced into nonmagnetic MoS with a 4|8ud-type grain boundary. Based on first-principles calculations, the V atomic chains show good thermodynamic stability and can self-assemble along the grain boundary direction.

Theranostic Rhenium(I)-Based ER-Phagy Retardant Promotes Immunogenic Cell Death.

ER-phagy is a double-edged sword in the occurrence, development, and treatment of cancer; especially, its functions in immunotherapy are still unknown. In this work, we designed a theranostic Re complex () containing a BODIPY-derived ligand and a β-carboline ligand to target the endoplasmic reticulum (ER) and block ER-phagy at the late stages. Interestingly, as validated both in vitro and in vivo, ER-phagy blockage greatly enhances the capability of to induce immunogenic cell death (ICD).

Foundation model of ECG diagnosis: Diagnostics and explanations of any form and rhythm on ECG.

We propose a knowledge-enhanced electrocardiogram (ECG) diagnosis foundation model (KED) that utilizes large language models to incorporate domain-specific knowledge of ECG signals. This model is trained on 800,000 ECGs from nearly 160,000 unique patients. Despite being trained on single-center data, KED demonstrates exceptional zero-shot diagnosis performance across various regions, including different locales in China, the United States, and other regions.

Synergistic Nonreciprocity of Linear and Nonlinear Optical Diffraction.

Linear optical diffraction of light is a basic natural phenomenon subject to a long history study and it obeys the well-known reciprocity in transport. In this work we report observation of synergistic nonreciprocal linear and nonlinear diffraction of a Ti:sapphire femtosecond laser beam against a periodic poled lithium niobate (PPLN) thin plate nonlinear grating with a front surface corrugated with a shallow grating of a depth only 67 nm and a smooth back surface. A high peak power pump laser beam shining upon the geometrically asymmetric nonlinear grating from either the front surface and back surface will both cause significant second-order nonlinear (2nd-NL) Raman-Nath diffraction and Cerenkov radiation, in addition to apparent linear optical diffraction and modest third-order nonlinear (3rd-NL) spectral broadening.

Naked-eye and fluorescence resonance energy transfer based ratiometric fluorescent probe for rapid, sensitive and selective detection of hydrazine and its applications in imaging of environmental samples and living systems.

The detection of hydrazine is essential for safeguarding human health. However, a tool capable of accurately detecting hydrazine across diverse sample types, such as soil, water sources, and plant specimens contaminated by hydrazine leakage, as well as cells and live mice containing endogenously generated hydrazine from drug metabolism, is still lacking.

Research progress on animal models of peritoneal adhesion.

Peritoneal adhesion is a common complication of abdominal and pelvic surgery that can cause various clinical symptoms, including abdominal pain, intestinal obstruction, and female infertility, significantly impacting patient quality of life. Animal models of peritoneal adhesion are important tools for studying the mechanisms of adhesion formation and evaluating the effectiveness of prevention and treatment. Various methods for constructing animal models of peritoneal adhesion include physical injury, chemical injury, ischemia, infection, foreign body stimulation, and simulated surgery; however, none can fully simulate peritoneal adhesion in patients clinically.

Extended One-Way Waveguide States of Large-Area Propagation in Gyromagnetic Photonic Crystals.

We propose extended one-way waveguide states of large-area propagation in a photonic crystal waveguide consisting of two honeycomb gyromagnetic photonic crystals with opposite external magnetic fields. When the width of the waveguide is small enough, the edge states along both boundaries of the waveguide couple with each other strongly and thus create the so-called extended one-way waveguide states. Of note, this structure supports both even and odd extended states, which can be excited under different excitation conditions.
