A new method for estimating forest aboveground biomass by integrating sUAV and satellite remote sensing
ABSTRACT Accurate forest aboveground biomass (AGB) estimation in mountainous regions is often constrained by limited field sampling and difficulties in linking field observations with satellite-scale remote sensing data. This study developed a cross-scale AGB estimation framework that uses small unmanned aerial vehicle (sUAV) LiDAR as an intermediate layer between field plots and Sentinel-2 imagery in the Helan Mountains, northwestern China.
Pavement crack detection and segmentation using nested U‐Net with residual attention mechanism
1 INTRODUCTION The precise and prompt evaluation of pavement conditions is crucial for transportation agencies to develop maintenance plans, select maintenance methods, and allocate budgets (Elhadidy et al., 2021; Shtayat et al., 2020). Pavement condition, as a crucial part of national infrastructure, significantly influences the efficiency and quality of transportation network operations (Underwood et al., 2017).

Stevie et al.2 discussed some of the “tricks of the trade” in sample handling and preparation for surface analysis (that typically go unpublished) and highlighted the utility of enlisting the expertise of analysts.
The impact of low-mode symmetry on inertial fusion energy output in the burning plasma state - Nature Communications
|
Abstract Indirect Drive Inertial Confinement Fusion Experiments on the National Ignition Facility (NIF) have achieved a burning plasma state with neutron yields exceeding 170 kJ, roughly 3 times the prior record and a necessary stage for igniting plasmas. The results are achieved despite multiple sources of degradations that lead to high variability in performance.

Tutorial: Simulating modern magnetic material systems in mumax3
Magnetic nanostructures hold significant potential as low-power components for information and communication technologies (ICT). However, to harness this potential and establish themselves as competitive platforms in the post-CMOS (complementary metal–oxide–semiconductor) era, efficient methods for controlling their magnetization states are essential. One approach to exerting torque on the magnetization is through the interaction with an injected spin-polarized current, known as spin torque.

Optimization of the tunneling magnetoresistance and spin-valley polarization in complex magnetic silicene structures
We now present the results about the spin- and valley-dependent transport properties in CMSSs. First, we will discuss the physical properties for the case of symmetrical structures (S-CMSSs). Then, by inducing structural asymmetry, we will deal with the so-called asymmetrical structures (A-CMSSs) as well as asymmetrical magnetic silicene superlattices (A-MSSLs) in order to compare the spin-valley polarization and tunneling magnetoresistance of aperiodic and periodic structures.
Samarium modified lead-free potassium sodium niobate-based grain orientation-controlled ceramics and its ultrasonic transducer applications
The x-ray diffraction (XRD) pattern of the textured Sm–KNLN–BZ–BNT ceramics is shown in Fig. 1(a). For comparison, an XRD pattern of non-textured Sm–KNLN–BZ–BNT ceramics in our previous work is exhibited in Fig. 1(a) too.20 Both textured and non-textured Sm–KNLN–BZ–BNT ceramics show a pure perovskite structure. Compared to the XRD pattern of non-textured ceramics, the (001)/(100) peaks of a textured one were much higher.
