This dataset contains the first-principles calculation data and Mathematica notebooks supporting the study of light-driven phonon dynamics and ferroelectric switching in bilayer hexagonal boron nitride (h-BN), as presented in the accompanying manuscript and Supplemental Material. The deposit includes density functional theory (DFT) total energies, structural and phonon information, dielectric-response data, fitted coupling coefficients, and Mathematica notebooks used to calculate potential-energy landscapes and simulate light-driven switching between the oppositely polarized AB and BA stacking configurations. Potential-energy landscape The notebook 2DPotential_energy_landscape.nb processes DFT total energies calculated for different amplitudes of the two interlayer shear modes, Q₄ and Q₅. It constructs the two-dimensional potential-energy surface V(Q₄, Q₅), extracts selected one-dimensional energy profiles, and identifies minimum-energy configurations and switching pathways. The corresponding energy data are provided in Vasp_datafiles/energy.dat. These calculations generate Fig. 1 of the main manuscript. Light-driven phonon dynamics and switching The notebook All_mechanism.nb contains the interaction potentials, equations of motion, and numerical simulations for six excitation mechanisms: Infrared-active excitation; Ionic Raman scattering (IRS); Impulsive stimulated Raman scattering (ISRS); THz sum-frequency excitation (THz-SFE); Infrared resonant Raman scattering (IRRS); Dynamical tilting of the double-well potential. Depending on the mechanism, the notebook calculates the applied electric-field pulse, time-dependent phonon amplitudes, trajectories in phonon-coordinate space, dynamically modified double-well potentials, and switching between AB and BA stacking. It generates Figs. 2 and 3 of the main manuscript and Figs. S2, S7–S11 of the Supplemental Material. The notebook ShearMode_PhaseControl.nb simulates infrared excitation of the two shear-mode components. It demonstrates control of their combined motion by varying the polarization angle and relative phase of the electric-field components. These calculations generate Fig. S12 of the Supplemental Material. Structural and phonon inputs The Vasp_inputs directory contains the relaxed bilayer h-BN structure (POSCAR), Born effective-charge tensors (BORN), phonon frequencies and eigenvectors (band.yaml), and phonon irreducible representations (irreps.dat). These inputs are used to construct phonon displacement patterns, calculate mode effective charges, and identify the symmetry and optical activity of the relevant modes. Coupling coefficients and dielectric-response data The Coefficients directory contains the calculations and intermediate data used to determine coupling parameters for the dynamical simulations: IRS_coefficients: angle-dependent ionic Raman coupling coefficients and the notebook Coefficient_Cs,a.nb, used to generate Fig. S3. ISRS_RamanTensor: frequency-dependent dielectric tensors for finite displacements along Q₄ and Q₅, together with Raman_Tensor.nb. Fits of the dielectric response as a function of phonon amplitude yield the Raman tensor elements used in the ISRS simulations and Fig. S4(a). THz-SFE_Raman_Tensor: Raman-tensor data and a Mathematica notebook for their angular dependence, used in the THz-SFE simulations and Fig. S4(b). IRRS_coefficients: angle-dependent nonlinear b coefficients for the shear modes and the higher-frequency mode combinations, together with b_coefficient.nb, used in the IRRS simulations and Figs. S5 and S6. Fitted parameters and figures The Vasp_datafiles directory contains the DFT energy data, fitted IRS coupling coefficients, double-well potential parameters, and coefficients describing the coupling between excited phonon modes and the double-well potential. The Figures directory contains the final figures used in the main manuscript and Supplemental Material. Usage The Mathematica notebooks require Wolfram Mathematica for execution. The accompanying README describes the directory structure, input files, notebook functions, and their correspondence to the manuscript figures. Preserve the supplied directory organization when extracting the archive and check the input paths in each notebook before running the calculations. The origin and fitting procedure of each coefficient set are documented in the corresponding subdirectories.

This working paper examines fisheries governance as a relationship between conservation, access to resources and the institutional conditions of compliance. It asks how maritime diplomacy can connect international commitments with national decisions affecting fishing activities, enforcement and the interests of coastal communities. The analysis considers the complementary responsibilities of coastal, flag and port States, together with the contribution of regional fisheries arrangements. It distinguishes scientific assessment, management decisions and enforcement authority, emphasising that effective conservation requires cooperation across these functions. Particular attention is given to information exchange, inspection, investigation and follow-up concerning suspected violations. The paper examines how differences in expertise, resources and administrative continuity influence participation and implementation. It also considers the distributional consequences of conservation measures and access arrangements for States, operators and communities. The argument is that adopting management rules provides one component of effective governance. Authorities must obtain reliable information, possess appropriate legal powers and coordinate responses through procedures that preserve accountability and applicable safeguards. The contribution is a framework for assessing fisheries cooperation through identifiable responsibilities and observable performance. It links conservation objectives with lawful access, institutional capacity and consequential enforcement, providing a basis for evaluating implementation deficiencies and developing targeted diplomatic and regulatory reforms.

This study presents the design and implementation of a web based E-Archive System intended to organize, review, publish, and retrieve student research outputs within an academic institution. The project addressed fragmented storage, inconsistent review workflows, and limited access to completed research documents by providing separate interfaces for students, faculty members, administrators, and public readers. A developmental research approach was used. The existing PHP and MySQL application was examined through source-code inventory, database-schema review, workflow tracing, interface revision, and PHP 5.6 compatibility testing. The resulting system supports account registration and approval, group assignment, research proposal submission, chapter-level document management, faculty announcements and comments, administrative approval and publication, public search, and configurable branding. The reviewed codebase contains 80 application PHP files outside bundled editor samples and 15 tables in the supplied database schema. Syntax verification confirmed that the revised application files parse under PHP 5.6.32. The interface was also consolidated around administrator-controlled title, logo, primary, banner, and text colors so public, student, faculty, and administrator pages share a consistent identity. Technical inspection nevertheless identified limitations in legacy request handling, unrestricted research-document uploads, hard-coded local URLs, and incomplete database constraints. Because the available evidence consisted of source files and a schema rather than participant data, findings are limited to implemented functionality, code-level observations, and repeatable compatibility checks; they do not represent measured user satisfaction. The study concludes that the system establishes a workable role-based research archive and workflow foundation, but production deployment requires systematic security hardening, controlled file preservation, database migration, backup, and formal usability evaluation.
