SUMMARY The b value is a critical parameter that has been used to describe spatial and temporal size distribution characteristics in data from both natural seismicity laboratory rock acoustic emission (AE) tests. However, unlike the magnitude for estimation earthquakes which corrects hypocentral distance, apparent amplitude of AE, most commonly AE test. This ignores effect attenuation, may modify frequency–amplitude affect results. Here, we investigate attenuation on estimate synthetic...
Abstract The Gutenberg‐Richter (G‐R) relationship has been regarded as the fundamental description of size distribution from large‐scale‐earthquake to small‐scale‐laboratory rock ruptures. However, because deviation G‐R often reported, especially when amplitude is used for b value estimation in acoustic emission testing, effect attenuation should be considered. Here, we perform a detailed analysis on law and discuss modification doubly truncated more general perspective. We find that will...

Abstract The climate reconstruction of the Tibetan Plateau, which was called Third Pole Environment, has been a research hotspot in recent years. However, there are few studies on C 3 and 4 plants evolution it is an area active debate whether existing Plateau. In this study, paleoclimate Hurleg Lake northeastern Plateau reconstructed based n ‐alkane‐induced indicators, while plant history established by compound‐specific isotope long‐chain ‐alkanes since 14.1 cal kyr BP. response to change...
Abstract Climate change, sea level fluctuations, and tectonic uplift play key roles in the evolution of sedimentary systems on continental margins. In Arabian Sea, Makran margin is suitable for studying these processes during Holocene due to its high sedimentation rate continuous sequence sediments. Here, high‐resolution clay mineral grain size analyses have been conducted better understand process controlling factors over past 13,000 yr. The results show that influence Indus‐derived...
The Eocene is the initial stage of Cenozoic global cooling. Compared with abundant marine records, continental records are scarce. Throughout Eocene, a series continuous deposition gypsum and volcanic tuff-bearing red clastic sediments have developed in Nangqian Basin (NB). In this work, representative were collected from NB, lipid biomarkers compound-specific carbon isotopes n -alkanes analyzed. Based on robust paleomagnetic age–depth model, early to late isotopic compositions (δ 13 C 23 δ...
Abstract Although previous studies have shown that the paleoenvironment and geological processes contributed to organic matter accumulation (OMA) carbon isotope excursions (CIEs) during late Ordovician–early Silurian, dominated controlling factor for OMA origins of CIEs still remains unclear due complex interaction between various paleoenvironmental factors processes. Therefore, based on elemental geochemistry Wufeng–Longmaxi Formation shales in upper Yangtze Platform, we analyzed Silurian...
State-of-Charge (SOC) estimation of supercapacitors has been extensively studied in the literature, with most existing studies focusing on SOC a single supercapacitor cell. However, practical applications, are often connected to balancing circuits eliminate cell imbalances. When circuit is activated, system dynamics switches new mode, implying that methods cannot be applied directly. In this paper, we switched systems approach estimate cells. We model switching for RC resistor and carefully...
There have been few high‐resolution investigations covering the last glacial and Holocene from Sichuan, Yunnan, or south Asia area in south‐west monsoon domain region. High‐resolution analyses of lake sediments retrieved Qionghai Lake, Sichuan Province, were conducted using a combination variables including total organic carbon (TOC) nitrogen (TN) concentration, low frequency magnetic susceptibility (χ LF ), particle size, carbonate content, δ 13 C value matter (δ org to provide new...
