title: Global Reservoir Dataset (GRD)

description: Description:This dataset contains spatial polygons and estimated storage capacities for 425,023 global reservoirs. The storage volumes (vol_rep_km3) are derived through a hierarchical approach: prioritizing reported values from GeoDAR and HydroLAKE, and falling back to size-dependent empirical area-volume power laws for unlisted reservoirs.

Column Descriptions:

- status: Operational status of the reservoir (e.g., 0=Stable, 1=Constructed, 2=Disappeared,). (Type: String)- change_year: Reservoir's "Constructed" or "Disappeared" year. (Type: Integer/Year)- lon: Longitude of the reservoir geometric centroid (WGS84). (Type: Decimal Degrees)- lat: Latitude of the reservoir geometric centroid (WGS84). (Type: Decimal Degrees)- area_km2: Surface area of the reservoir water body. (Unit: km2)- geometry: Polygon geometry defining the reservoir boundary. (Type: Shapefile Polygon)- source: Source identifier for the reservoir boundary data. (Type: String)- vol_rep_km3: Representative storage volume. This is the best-available estimate, combining direct records and empirical modeling. (Unit: km3)- vol_source: Metadata indicating the origin of the volume estimate (e.g., 'GeoDAR', 'HydroLAKE', or specific empirical equation name). (Type: String)

title: [2025-10-08v2]A Unified Proof of the Collatz Conjecture The Invariant Structure of the $3n+1$ Problem large Generalization to All Integers via Phase Expression Theory and Universal Structural Limits.pdf

description: This paper presents a \textbf{unified and constructive framework} that resolves the long-standing open problem, the \textbf{Collatz Conjecture} ($3n+1$), over all non-zero integers (positive and negative). We introduce the \textbf{Collatz Phase Expression (CPE)}, which models the Collatz map as deterministic geometric transformations. The CPE utilizes the \textbf{Alternating Binary Notation (ABN)}, a method that encodes integers as alternating-sign powers of 2, and decomposes this into structural units: Chain ($\mathbf{R}$), Single ($\mathbf{T}$), and Node ($\mathbf{K}$). Using the CPE's characteristic quantities ($\mu$: unit count, $H_{RT}$: complexity, $B$: bit-length), we establish two \textbf{Universal Structural Limits}. These constraints imply that infinite divergence and non-trivial cycles are structurally impossible: \begin{enumerate} \item A strict linear bound on the total bit-length, $B(F^m (n)) \le B(n) + m$, prevents exponential growth. \item A deterministic, self-regulating trade-off for the local complexity $H_{RT}$ is enforced by the **Fundamental Inequality**, ensuring complexity cannot increase unboundedly. \end{enumerate} These structural constraints demonstrate that every positive sequence converges to the minimal complexity state ($\mathbf{H_{K}=0}$), leading exclusively to the trivial loop $\{1\}$. Furthermore, the same formalism resolves the negative Collatz conjecture by establishing a universal structural upper bound ($\mathbf{H_{RT} &lt; 6}$), which guarantees convergence to the known finite loops (including $\{-1, -3, -11\}$ cycles). The CPE framework provides a deterministic lens for analyzing discrete dynamical systems.

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.
