title: River Capture, Palinology, Geochronology, Paleoenvironmental indicators

description: The research aimed to evaluate the paleoindicators of the capture process of the Guaratuba River, located in a humid tropical environment. Morphometric aspects and sedimentary and organic materials covering the surface of the dry valley were used as explanatory paleoenvironmental indicators. Samples were collected in the basin divide between the upper Guaratuba and the Claro River, for integrated evaluation of macromorphological, granulometric, morphoscopic, mineralogical, geochronological and palynological data. The samples of sandy material were subjected to absolute dating by Optically Stimulated Luminescence (OSL), while those of organic material were subjected to absolute dating of 14C. The covering materials were classified in the macromorphological analysis as Gleysols, Spodosols and Cambisols. The Spodosol presents itself as a paleosol and the Ortstein horizon as a lithostratigraphic indicator. In the granulometric analysis, the sand fraction predominated in all horizons described, as well as quartz and mica in the mineralogical analysis. In the morphoscopic analysis of the sand fraction, extensive rounding of the gravels and quartz grains was observed in all horizons, which indicates that these sediments suffered mechanical erosion in the past by current flow or torrent deposition, indicating paleoclimate and water conditions different from those of today. The morphometric characteristics of the basins attest to the rejuvenation of the Guaratuba basin in response to capture. The dates indicate specific humid periods of the Holocene, Pleistocene and Last Glacial Maximum linked mostly to the precipitation conditions in the Southeast region. The covering materials of the dry valley, as well as the hydrodynamics of the river channels, have been worked by the humidity cycles in the system for at least 36,500 years B.P. It is possible to link the change in the base level between the rivers and the consequent capture of the Guaratuba to the Last Glacial Maximum, approximately 25,000 years B.P. The taxon assembly formed by Podocarpus sp, Ilex sp, Symplocus sp, Weinmannia sp, Myrsine sp, Alchornea sp, Mytenyus sp, Hedyosmum sp, Myrtaceae, Poaceae and Asteraceae families respond as indicators of humid and/or flooded paleoforests and cold and humid paleoclimates. The taxa found, for the most part, adapted to cold and humid forest environments and constantly or seasonally flooded, indicate an ancient marshy region in the current dry valley. Captures are essential for the evolution of the Serra do Mar and the coastal plain in Southeast Brazil, having as a driving force the humid regional climate condition. The use of the systemic approach for the study of captures, based on interdisciplinary techniques, becomes essential to elucidate in its results the positive response of paleoenvironmental indicators at regional and local levels.

title: Targeted profiling the intestinal microenvironment via novel non-invasive sampling capsule endoscope

description: Intestinal flora and metabolites are associated with multiple systemic diseases. Current approaches for acquiring information regarding microbiota/metabolites have limitations. We aimed to develop a precise sampling capsule endoscopy (SCE) for the convenient, non-invasive, and accurate acquisition of digestive bioinformation for disease diagnosis and evaluation. The SCE was used for sampling ileum content from both normal and inflamed segments in Labradors. The GI liquid was then used for microbiome profiling and metabolomics profiling.

title: Data Entitlement Granularity and Corporate Personal Data Protection Efficacy

description: This study utilizes a sample of Chinese A-share listed firms covering the period from 2016 to 2023, with data obtained from the China Stock Market and Accounting Research database, which offers comprehensive firm-level data including fundamentals, financial statements, and corporate governance attributes. The choice of 2016 as the initial year aligns with Chen et al. (2024a), recognizing its pivotal role in marking the formal initiation of China's digital strategy. Specifically, the 2016 G20 Initiative on Digital Economy Development and Cooperation introduced key concepts such as the "digital economy" and "corporate digital transformation" into China's national strategic framework. Subsequently, the issuance of the 2019 Draft Measures for Data Security Management, the promulgation of the 2021 PIPL, along with the 2022 Cybersecurity Classified Protection System 2.0, collectively enhanced the regulatory environment concerning data security and privacy compliance. This progressive institutional evolution provides a solid foundation and theoretically justified context for investigating PDPE.
Sample construction follows a rigorous screening protocol. (1) Financial institutions are excluded due to their distinct regulatory frameworks and balance sheet structures; (2) Firms classified under Special Treatment status are omitted to prevent potential distortions arising from financial distress or operational anomalies; (3) Firm-year observations with incomplete data for critical model variables are removed to ensure the integrity and robustness of the analysis. Consequently, the final dataset comprises 26,893 firm-year observations, representing 4,684 unique listed firms.

title: SH1066006.10FU

description: UNITE provides a unified way for delimiting, identifying, communicating, and working with DNA-based Species Hypotheses (SH). All fungal ITS sequences in the international nucleotide sequence databases are clustered to approximately the species level by applying a set of dynamic distance values (<0.5 - 3.0%). All species hypotheses are given a unique, stable name in the form of a DOI, and their taxonomic and ecological annotations are verified through distributed, web-based third-party annotation efforts. SHs are connected to a taxon name and its classification as far as possible (phylum, class, order, etc.) by taking into account identifications for all sequences in the SH. An automatically or manually designated sequence is chosen to represent each such SH. These sequences are released (https://unite.ut.ee/repository.php) for use by the scientific community in, for example, local sequence similarity searches and next-generation sequencing analysis pipelines. The system and the data are updated automatically as the number of public fungal ITS sequences grows.
