Abstract	Stable isotope ratios are widely used to solve environmental, geological, medical, and forensic problems. The double spike technique is considered to be one of the most robust and efficient methods to correct for instrumental mass bias and isotopic fractionation that may occur during sample preparation. However, various hidden errors can arise from data processing and have been largely overlooked in previous studies. Several of these hidden errors were investigated in this work using measurement and synthetic data. Double spike inversion of chromium isotope raw data from 1116 natural samples demonstrated that averaging raw isotope ratios before double spike inversion can add significant errors to inverted isotope values, and such errors can be 1.5 times larger than the true analytical precision. Synthetic data were used to investigate the errors on inverted Cr isotope data caused by spike:analyte ratio and Fe-Ti-V interferences, and the following threshold values are recommended to minimize such errors:

Abstract	Stable isotope ratios are widely used to solve environmental, geological, medical, and forensic problems. The double spike technique is considered to be one of the most robust and efficient methods to correct for instrumental mass bias and isotopic fractionation that may occur during sample preparation. However, various hidden errors can arise from data processing and have been largely overlooked in previous studies. Several of these hidden errors were investigated in this work using measurement and synthetic data. Double spike inversion of chromium isotope raw data from 1116 natural samples demonstrated that averaging raw isotope ratios before double spike inversion can add significant errors to inverted isotope values, and such errors can be 1.5 times larger than the true analytical precision. Synthetic data were used to investigate the errors on inverted Cr isotope data caused by spike:analyte ratio and Fe–Ti–V interferences, and the following threshold values are recommended to minimize such errors: ⁵⁴Crₛₚᵢₖₑ/⁵²Crₛₐₘₚₗₑ ratio greater than 0.5, ⁵⁶Fe/⁵²Cr less than 0.2, ⁴⁹Ti/⁵²Cr less than 0.04, and ⁵¹V/⁵²Cr less than 1. Sample preparation can potentially lead to large errors in inverted Cr isotope data if preparation-induced isotope fractionation deviates from the exponential law used in the double spike inversion, but such errors can be minimized by achieving >70% Cr yield. Our findings provide important insights for the double spike inversion procedure and assessing the reliability of inverted isotope data for not only the chromium isotope system but also other elements commonly analyzed using the double spike technique.

Abstract	Double spike (DS) method has been extensively used in determining stable isotope ratios of many elements. However, challenges remain in obtaining high-precision isotope data for ultra-trace elements owing to the limitations of instrumental signal-to-noise ratios and the systematics of precision of DS-based measurements. Here, the DS-standard addition (SA) (DSSA) technique is proposed to improve measurements of isotope compositions of ultra-trace elements in natural samples. According to the U-shaped relationship between DS measurement uncertainty and the spike/sample ratio, theoretical equations and an error propagation model (EPM) were constructed comprehensively. In our method, a spiked secondary standard solution with a high, precisely known spike/sample ratio is mixed with samples such that the mixtures have spike/sample ratios within the optimal range. The abundances of the samples relative to the added standards (sample fraction; f ₛₚₗ) and the samples’ isotope ratios can then be obtained exactly using a standard DS data reduction routine and the isotope binary mixing model. The accuracy and precision of the DSSA approach were verified by measurements of cadmium and molybdenum isotopes at as low as 5 ng levels. Compared with traditional DS measurements, the sample size for isotope analysis is reduced to 1/6–1/5 of the original with no loss of measurement precision. The optimal mixing range f ₛₚₗ = 0.15–0.5 is recommended. The DSSA method can be extended to isotope measurement of more than 33 elements where the DS method is applicable, especially for the ultra-trace elements such as platinum group and rare earth element isotopes.

Abstract	Variability in detrital trace-metal (TM) concentrations adversely affects the accuracy and uncertainty of using TM concentrations in siliciclastic marine sediments to decipher paleoceanographic conditions. Here we analyze massive TM datasets for rocks, soils, and stream sediments collected across the conterminous United States to quantify the effects of weathering and fluvial transport on the concentrations and variabilities of commonly used TMs (Al, Ti, Ba, Cr, Fe, Li, Ni, U, V) in detrital materials. Titanium (Ti) is preferred as the normalization element due to its lower mobility compared to aluminum (Al). Median TM/Ti ratios decrease by up to 25% from solid rocks to fluvial sediments, while standard deviations (SD) decrease by up to 90%, indicating that weathering and fluvial transport reduce not only TM/Ti ratios but also their ranges of variation. At a regional scale, median TM/Ti ratios in soils and sediments deviate significantly from commonly used global standards (Post-Archean Australian Shales and Upper Continental Crust). This means that, for normalization purposes, it is necessary to constrain the detrital TM/Ti ratios for each drainage basin under study rather than making use of a global standard. Sensitivity analyses demonstrate that the modification of median TM/Ti by weathering and fluvial transport processes can lead to significant systematic errors in detrital-corrected TM concentrations. Although weathering and fluvial transport can significantly reduce the variabilities of detrital TM/Ti ratios, the remaining variance is still significant and should be propagated into uncertainties in the corrected TM concentrations.

Abstract	Background: In recent years, with the accelerated pace of life, diet, environmental problems occur frequently. External factors are easily to cause endocrine disorders and hormone sensitivity of breast tissue, which can lead to mammary hyperplasia. The incidence rate of hyperplasia of mammary glands is increasing year by year, and the age of onset is also getting lower and lower. If not treated in time, there is a crisis of breast cancer.Clinical studies have found that auricular point pressing therapy is widely used in clinical treatment of mammary hyperplasia recently, but the efficacy of massage in the treatment of mammary hyperplasia has not been systematically reviewed. The purpose of this study is to explore the efficacy, safety and effectiveness of auricular point pressing therapy in the treatment of hyperplasia of mammary glands. Methods: We will search PubMed, Web of Science, Cochrane Library, EMBASE, Wan fang Database, Chinese Scientific Journal Database, CNKI, VIP, and Chinese Biomedical Literature Database. The retrieval date was January 10, 2021. RevMan 5.3 software was used to evaluate the quality and risk of included studies. The efficacy, recurrence rate, and symptom score of breast hyperplasia were analyzed, and the results were observed and measured. Results: This study will be from the clinical efficiency, improvement rate, pain symptoms disappear rate, tumor size improvement rate, and other aspects of the existing evidence for a high quality synthesis, as well as auricular point pressing therapy adverse events. Conclusion: the conclusion of this review will provide the basis for judging whether auricular point pressing therapy is safe and effective in the treatment of hyperplasia of mammary glands. Ethics and dissemination: This systematic will evaluate the effectiveness and safety of auricular point pressing therapy in the treatment of hyperplasia of mammary glands. As all data used in this systematic review and meta-analysis have been published, ethical approval is not required for this review. Protocol registration number: INPLASY202110028.

Abstract	High gravity technology, as a process intensification technology, has demonstrated the great advantages in the field of gas purification on account of its excellent mass transfer efficiency and energy-efficient, but it is rarely applied in the field of nitrogen oxides (NOx) purification of marine diesel engine exhaust. In this paper, a high-gravity bowl-shaped-disk rotating bed (HBRB) without catalytic was designed for diesel exhaust after-treatment. A diesel oxidation catalyst (DOC) was installed in the front of the HBRB to regenerate more nitrogen dioxide (NO₂) easily reduced by urea. A bench test of a 6-cylinder marine diesel engine with the HBRB was carried out. The effects of the HBRB speeds, urea concentrations, and engine operating conditions on NOx purification efficiency in engine exhaust were experimentally investigated. The experimental result indicates that the maximum NOx removal efficiency of the HBRB can reach 69.1%. The improvement of the NOx removal efficiency is not obvious at the HBRB speed of over 1500 r/min. The pre-oxidation degree of nitric oxide (NO) and urea concentration largely affect the NOx removal efficiency. The HBRB has great potential in marine diesel engine exhaust denitration.

Abstract	A pair of extensively modified microtubules form the central apparatus (CA) of the axoneme of most motile cilia, where they regulate ciliary motility. The external surfaces of both CA microtubules are patterned asymmetrically with large protein complexes that repeat every 16 or 32 nm. The composition of these projections and the mechanisms that establish asymmetry and longitudinal periodicity are unknown. Here, by determining cryo-EM structures of the CA microtubules, we identify 48 different CA-associated proteins, which in turn reveal mechanisms for asymmetric and periodic protein binding to microtubules. We identify arc-MIPs, a novel class of microtubule inner protein, that bind laterally across protofilaments and remodel tubulin structure and lattice contacts. The binding mechanisms utilized by CA proteins may be generalizable to other microtubule-associated proteins. These structures establish a foundation to elucidate the contributions of individual CA proteins to ciliary motility and ciliopathies.
