A treasure trove of Cambrian secrets Animal life exploded in diversity and form during the period about 500 million years ago. Fu et al. describe an early fossil site China that contains a variety specimens, more than half which are previously undescribed (see Perspective by Daley). The rivals described sites, such as Burgess Shale, should help to elucidate biological innovation diversification this period. Science , issue p. 1338 ; see also 1284
Abstract The pattern and timing of deformation in southeast Tibet resulting from the early stages India-Asia collision are crucial factors to understand growth Tibetan Plateau, but they remain poorly constrained. Detailed field mapping, structural analysis, geochronological thermochronological data along a 120 km section Ludian-Zhonghejiang fold-and-thrust belt bounding Jianchuan basin western Yunnan, China, document Cenozoic tectonic evolution conjunction between Lanping-Simao South China...
The tassel development status and its branch number in maize flowering stage are the key phenotypic traits to determine growth process, pollen quantity of different varieties, detasseling arrangement for seed production fields. Rapid accurate detection tassels is great significance breeding production. However, due complex planting environment field, such as unsynchronized vary size shape caused by remains challenging problem, existing methods also cannot distinguish early tassels. In this...
Abstract The Karakoram fault (KKF) is an important strike‐slip boundary for accommodating deformation following the India‐Asia collision. However, whether confined to crust or it extends into mantle remains highly debated. Here, we show that KKF overwhelmingly dominated by crustal degassing related a 4 He‐ and CO 2 ‐rich fluid reservoir (for example, He contents up ∼1.0–1.6 vol.%; 3 He/ = 0.027 ± 0.013 R A (1 σ , n 47); /N 3.7–57.8). Crustal‐scale active driven faulting could mobilize from...
Sulfate reduction is an essential metabolism that maintains biogeochemical cycles in marine and terrestrial ecosystems. reducers are exclusively prokaryotic, phylogenetically diverse, may have evolved early Earth's history. However, their origin elusive unequivocal fossils lacking. Here we report a new microfossil, Qingjiangonema cambria, from ∼518-million-year-old black shales yield the Qingjiang biota. long filamentous form comprising hundreds of cells filled by equimorphic equidimensional...
Black-box textual adversarial attacks are challenging due to the lack of model information and discrete, non-differentiable nature text. Existing methods often versatility for attacking different models, suffer from limited performance inefficient optimization with word saliency ranking, frequently sacrifice semantic integrity achieve better attack outcomes. This paper introduces a novel approach attacks, which we call Cross-Entropy Attacks (CEA), that uses address above issues. Our CEA...
The India-Eurasia collision during the Cenozoic has established widespread fold-and-thrust belts in Eurasia continental interiors, which are important for understanding intracontinental convergence processes and have been proved to be rich hydrocarbon resource. Despite significance, structures along eastern Pamir foreland blind covered by monocline, hinders mechanism of potential exploration targets comprehensively understood. In this study, we deciphered Qimugen belt on with interpretations...
The utilization of laterite sulfuric acid leach residue has always been a challenge in the metallurgical industry. current treatment involves deep-sea landfills, which leads to considerable environmental pollution and resource wastage. In this work, an effective method is proposed recover iron chromium from residue. effects roasting temperature, reducing agent dosage, reaction duration on recovery were investigated. optimum conditions as follows: temperature 1200 °C, dosage 30%, 60 min....

The oxygenation of Earth's atmosphere is widely regarded to have played an important role in early-life evolution. Chromium (Cr) isotopes recorded sedimentary rocks been used constrain the atmospheric oxygen level (AOL) over geological times based on fact that a positive Cr isotopic signature linked presence Cr(VI) as result oxidative continental weathering. However, there no direct evidence yet. Carbonates are most distributed and were thought incorporated directly from seawater. Here, we...
