Abstract Biochar has been proposed as a promising negative CO 2 emission technology to mitigate future climate change with the additional benefit of increasing agricultural production. However, spatial responses soil organic carbon (SOC) biochar addition in cropland are still uncertain, and economic feasibility large‐scale implementation remains unclear. Here, we analyzed response SOC using 389 paired field measurements. The results show that significantly increased by 45.8% on average large...
The production of bioenergy with carbon capture and storage (BECCS) is a pivotal negative emission technology. cultivation dedicated crops for BECCS impacts the temperature through two processes: net CO2 removal (CDR) from atmosphere (biogeochemical cooling) changes in local energy balance (biophysical warming or cooling). Here, we compare magnitude these processes key grass tree species envisioned large-scale crop cultivation, following economically plausible scenarios using Earth System...
Mastoidectomy is critical in acoustic neuroma surgery, where precise planning of the bone milling area essential for surgical navigation. The complexity representing irregular volumetric and presence high-risk structures (e.g., blood vessels nerves) complicate this task. In order to determine mill using preoperative CT images automatically, we propose an automated method evolutionary multi-objective optimization safer more efficient plans. High-resolution segmentation adjacent risk performed...
A novel compound band imaging (CBI) endoscopy system is introduced to enhance the visualization and depth differentiation of blood-containing tissues within mucosal structures. This serves as a theranostics tool supplement white light (WLI), enabling more precise disease diagnosis treatment. The utilizes combination green red narrow-band light, alongside amber wide-band synchronized with rapid switching strategy color CMOS sensor. design effectively avoids potential hardware cost increases...
Tropical moist forests have been severely affected by natural and anthropogenic disturbances, leading to substantial changes in global carbon cycle climate. These effects received great attention scientific research debates. Here we review recent progress on drivers ecological impacts of tropical forest their monitoring modeling methods. Disturbances are primarily driven clearcutting, selective logging, fire, extreme drought, edge effects. Compound disturbances such as fire aggravate...
Abstract A variety of drought indices have been constructed to monitor agricultural using ground‐based observations and satellite data. The focus on diverse aspects may applicability in different regions. We calculated seven popular evaluated their performances monitoring the main regions China (i.e., Northeast China, North Plain, middle‐and‐lower reaches Yangtze River, Sichuan Basin). independent assessment data used here included three aspects: soil moisture, vegetation photosynthesis...
Abstract. Biochar (BC) application to croplands aims sequester carbon and improve soil quality, but its impact on organic (SOC) dynamics is not represented in most land models used for assessing land-based climate change mitigation; therefore, we are unable quantify the effects of biochar under different or management conditions. Here, fill this gap, implement a submodel represent microbial decomposition model named MIMICS (MIcrobial-MIneral Carbon Stabilization). We first calibrate validate...
Abstract Tropical forests store about 70% of the total living biomass on land and yet very little is known changes in this vital carbon reservoir. Changes their stock, determined by input (i.e., net primary production [NPP]) turnover time ( τ ), are critical to global sink. In study, we calculated transient tropical forest using satellite‐based moderate‐resolution imaging spectroradiometer (MODIS) NPP analyzed trends from 2001 2012. Results show that generally have opposite across tropics....
Based on the daily rainfall data of 127 stations from 1960 to 2014, this study investigated spatial-temporal variation PCD (precipitation-concentration degree) and PCP period), their possible relations with ENSO (El Niño-Southern Oscillation) in middle lower reaches Yangtze River China. Main results have indicated that, firstly, mean was generally below 0.5 across whole area, value located northeast south. Besides, there a positive trend concentrated precipitation west part while negative...
The flue gas after wet desulfurization carries a lot of water content and energy, so it is an effective method to improve the thermal efficiency boiler by recovering waste heat through spray condensation. numerical model condensation established, its rationality validated with experimental verification. effects structural parameters such as layer spacing, angle, relative position layer, nozzle density, condensing tower height, operating droplet diameter, liquid-gas ratio, temperature, speed,...

In online social network, relations among users can be treated as a graph, which is very common data structure handled in computers. Diagrams are widely used to represent the graph visually, and it better idea show user's friends there visualization diagrams than simply list them one by one. There have been only few algorithms for generating undirected self-centered graph. This paper presents method of visualizing each user moreover, we friend group recommendation based on generated
