Carbon emission assessment of tunnel infrastructures: From construction to operation

Deep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

An Ocular Surface‐Targeting Nucleic Acid Hydrogel for Efficient Dry Eye Disease Treatment

Exploration, EarlyView.
A self‐assembled nucleic acid hydrogel modified with mucin‐1 (MUC1) aptamer is developed, which can actively target the mucin layer on the ocular surface and significantly extend its retention time after distillation. Inside the hydrogel, therapeutic siRNA is embedded and can effectively silence the inflammation gene expression, subsequently restoring ...

Low-voltage micro-arc discharge-grinding hybrid machining: Discharge energy regulation for high-surface-quality machining of Inconel 718

Materials & Design
Electric arc machining (EAM) of Inconel 718 often produces thick recast layers and severe thermal damage because of sustained high-energy discharge. This study proposes low-voltage micro-arc discharge-grinding hybrid machining (LV-MADG), in which low ...

Multi-Objective Optimization of Process Parameters for Powder Mixed Electrical Discharge Machining of Inconel X-750 Alloy Using Taguchi-Topsis Approach

Journal of Mechanical Engineering, 2021
The paper investigates the influence of boron carbide powder (B4C) mixed in dielectric fluid on EDM of Inconel X-750 alloy. The process parameters selected as discharge current (Ip), pulse on time(Ton), pulse off time(Toff), boron carbide(B4C) powder ...

Quantization of Polaritons Confined in Dielectric Structures

Laser &Photonics Reviews, EarlyView.
This study addresses the limitations of the Hopfield model of strong light‐matter coupling in the case of structured dieletrics. A method to derive quantum models in the polariton basis using Bogoliubov transformation and third quantization is introduced, demonstrating how to boost interaction strength and engineer nonlocal interactions for strongly ...

Bio‐Derived Nanophotonic Hybrids Enabling Reconfigurable Upconversion for Multilevel Optical Encryption

Laser &Photonics Reviews, EarlyView.
A dual‐gated nanophotonic platform integrates lanthanide‐doped upconversion nanoparticles with a stimuli‐responsive silk–zirconia photonic crystal to enable multilevel optical encryption. Resonant photonic coupling allows hydration‐dependent modulation of visible emission under near‐infrared excitation, achieving reversible switching between decoy and ...

Lonely and Sick: The Role of Social Media in Consumer Practices of Relief

Psychology &Marketing, EarlyView.
ABSTRACT Loneliness is increasingly recognized as a major mental health concern, yet the role of social media in alleviating it remains poorly understood. This study asks how social media help consumers cope with loneliness amid chronic illness. Focusing on women living with endometriosis, an under‐recognized and often stigmatized condition marked by ...

Parametric evaluation of electrical discharge coatings on nickel-titanium shape memory alloy in deionized water

Heliyon, 2020
Nickel-titanium shape memory alloy (NiTi) has a unique capacity to restore its initial shape after deformation, which is highly applicable to orthopaedic implantations, especially for the minimization of invasive surgeries.

Scale dependence of the marine atmospheric boundary‐layer response to ocean surface‐temperature variability in the EUREC4$$ {\mathrm{EUREC}}^4 $$A region

Quarterly Journal of the Royal Meteorological Society, EarlyView.
With a minimal physics model and a high‐resolution fully 3D simulation, we demonstrate that the marine atmospheric boundary layer (MABL) response to sea‐surface temperature (SST) variability displays a dependence on the horizontal scales of motion.

AUGURAL TERRITORIES: On the Prophetic Organizing of the Mid‐range

International Journal of Urban and Regional Research, EarlyView.
Abstract In this article I introduce the concept of augural territories to theorize the urbanism that emerged during pandemic lockdowns. I draw on ethnographic research in Madrid to examine how community‐based responses—including mutual aid networks, food pantries and neighbourhood associations—disrupted the spatial and temporal logics of territorial ...
