不同贮藏温度下绿豆汤红变对其功能组分、生物活性及感官品质的影响
Abstract: Mung bean soup (MBS), as a traditional Chinese beverage renowned for its efficacy in "clearing summer heat", is rich in phenolic compounds and possesses significant antioxidant and anti-inflammatory activities. However, it is highly susceptible to reddening. Currently, the changes in bioactive components, functional activities, and sensory qualities associated with the reddening of MBS remain insufficiently understood.

Exploring the Impact of NRF2 Signaling on Atherosclerosis: Insights Into Hydrogen Sulfide, NLRP3 Inflammasome, microRNAs, and HO‐1
This manuscript provides a comprehensive synthesis of current evidence elucidating the cytoprotective role of the NRF2 signaling pathway in atherosclerosis (AS). Specifically, it examines the regulatory mechanisms by which hydrogen sulfide (H₂S), microRNAs (miRNAs), the NLRP3 inflammasome, and heme oxygenase-1 (HO-1) modulate atherogenesis through the NRF2 signaling axis.

Chiral topological bound states in the continuum within photonic crystal cavities
We propose a magneto-optically tunable platform for chiral topological bound states in the continuum (BICs) within photonic crystal cavities. By integrating magneto-optical (MO) materials into topological bulk-state cavities, we demonstrate dynamic control over circular polarization states through external magnetic fields, a capability unattainable with conventional symmetry-breaking approaches.
Skin effect enhancement through symmetry breaking in reciprocal photonic crystals
Enhancing the skin effect in non-Hermitian photonic crystals has traditionally required alternating materials with different gain and loss characteristics inside the basic unit, which not only increases fabrication complexity but also faces limitations due to different material compatibility and material integrations.
Edge and skin effects in rhombus reciprocal photonic crystals
With the development of non-Hermitian physics, the non-Hermitian skin effect (NHSE) has attracted much attention. Existing research highlights the critical roles of the periodic boundary condition (PBC) spectrum, lattice symmetry, and macroscopic symmetry of the lattice in relation to the geometry-dependent skin effect (GDSE). However, the impact of macroscopic edge geometry is frequently neglected.

High-quality on-chip entangled photon source with broad tunable range based on coupling compensation
This paper introduces a tunable and high-quality photon source that utilizes evanescent-wave coupling phase matching. By adjusting the coupling gap, the signal light can be tuned from 1307 nm to 1493.9 nm, and the idler light can be tuned from 1612.8 nm to 1907 nm. Throughout the entire tuning range, the purity of the photon pairs remains above 92%.
Topological protection of dual-polarization biphoton states in photonic crystals
Polarization control is a major issue in topological quantum optics that limits reliable generation and transmission of quantum states. This study presents what we believe to be a novel topological photonic crystal design that provides topological protection for biphoton pairs for both TE and TM polarization. By well-designed cell configurations within the lattice, two topological boundaries emerge that can accommodate TM and TE modes at the same time.
Fog climatology at Shanghai Pudong International Airport
1 INTRODUCTION Fog is one of the critical meteorological conditions affecting airport operations. Each airport has specific operation standards, among which visibility, or runway visual range, is one of the deciding factors. Operations will be suspended if the visibility does not meet the minimum airport operation standards.
Effective enhancement of the non-Hermitian corner skin effect in reciprocal photonic crystals
With the rich physical phenomena arising from non-Hermitian systems, the non-Hermitian skin effect (NHSE) has become a current research hotspot. Nowadays, the corner skin effect based on non-reciprocal photonic crystals has been proposed. Considering the complexity of realizing non-reciprocity, the corner skin effect based on reciprocal photonic crystals is well worth investigating.
Deep learning model for dynamic color design of all-dielectric metasurfaces
Silicon nanostructure colors have rapidly developed in recent years, offering high resolution and a broad color gamut that traditional pigments cannot achieve. The reflected colors of metasurfaces are determined by the geometric structure of the unit cell and the refractive index matching layer parameters. It is evident that the design of specific colors involves numerous parameters, making it challenging to achieve through conventional calculations.

Inverse design of a photonic moiré lattice waveguide towards improved slow light performances
Abstract Slow light waveguides in photonic crystals are engineered using a conventional method or a deep learning (DL) method, which is data-intensive and suffers from data inconsistency, and both methods result in overlong computation time with low efficiency. In this paper, we overcome these problems by inversely optimizing the dispersion band of a photonic moiré lattice waveguide using automatic differentiation (AD).
Rhizosphere Soil Fungal Diversity and Soil Physicochemical Properties of Different Vegetations in Tundra of Changbai Mountain
1. Introduction Changbai Mountain is the highest mountain system in the eastern margin of Eurasia. The main peak Baiyun Peak is also the first peak in Northeast China. The only alpine tundra in Northeast China is of great significance for maintaining regional animal and plant habitats, biodiversity and regional ecological balance (Wu et al., 2002) . However, the degradation of the tundra caused by climate problems is a serious problem facing the tundra at present.

Abstract We proposed an effective approach to enlarge the slow light bandwidth and normalized-delay-bandwidth product in an optimized moiré lattice-based photonic crystal waveguide that exhibits intrinsic mid-band characteristics. A flatband corresponding to a nearly constant group index of 34 over a wide bandwidth of 82 nm centered at 1550 nm with near-zero group velocity dispersion was achieved.

Experimental demonstration of a graphene-based hybrid plasmonic modulator
Abstract In this Letter, we report a graphene-based hybrid plasmonic modulator (GHPM) realized by employing the electro-absorption effect of graphene. The simulation results show that the modulation efficiency of GHPM, i.e., extinction ratio per length, can be as large as 0.417 dB/μm, which is more than twice as much as that of recently presented graphene-on-silicon modulator.
