SISTEM INFORMASI PENILAIAN KINERJA PEGAWAI BERBASIS WEB SEBAGAI SOLUSI DIGITALISASI SDM

Employee performance assessment is a critical component of human resource management in any organization. However, many organizations still rely on conventional spreadsheet-based methods that result in calculation errors, delayed reporting, subjective evaluations, and data manipu...

Bipartite entanglement harvesting with multiple detectors

We study bipartite entanglement harvesting from the quantum vacuum of a massless scalar field between two subsystems, each composed of a finite number of Unruh-DeWitt detectors. Using perturbation theory, we show that the leading-order negativity is fully determined by a submatri...

Inflationary magnetogenesis from nonminimal coupling in large- and small-field potentials

We investigate inflationary magnetogenesis in a scenario where conformal invariance of electromagnetism is broken through a \emph{non-minimal Yukawa-like coupling between the inflaton and the Ricci scalar}. We account for electromagnetic backreaction and the Schwinger effect, ana...

Spectrum analysis with quantum dynamical systems. II. Finite-time analysis

The prequel to this work [Ng et al., Phys. Rev. A 93, 042121 (2016)] proposes the method of spectral photon counting to enhance noise spectroscopy with an optical interferometer. While the predicted enhancement over homodyne detection is promising, the results there are derived b...

CodaRAG: Connecting the Dots with Associativity Inspired by Complementary Learning

Large Language Models (LLMs) struggle with knowledge-intensive tasks due to hallucinations and fragmented reasoning over dispersed information. While Retrieval-Augmented Generation (RAG) grounds generation in external sources, existing methods often treat evidence as isolated uni...

Realistic Pearl vortices in thin film superconductors

We analyze magnetic field profiles of vortices in thin-film superconductors, shedding new light on this old and presumed settled problem. In sufficiently thin films with realistic Ginzburg-Landau parameter $κ= 1/\sqrt{2}$, the magnetic screening around a vortex core is neither ex...

Meso-NH-ISO v1.0: a water stable isotopologue scheme in the non-hydrostatic mesoscale atmospheric model Meso-NH – application to a 2D West African squall line

Abstract. Better understanding how convective processes impact the isotopic composition of atmospheric water has implications for understanding present-day phenomena such as squall lines or tropical cyclones, and for reconstructions of past rainfall extreme events. With this moti...

Distinguishing relapse from sustained remission in acute myeloid leukemia. Lineage-specific developmental stage distributions

We characterize bone marrow cell populations at minimal residual disease (MRD) by their distribution across hematopoietic developmental stages within each major lineage. Using the BoneMarrowMap atlas (263.159 reference cells, 24 broad cell types) as a coordinate system, we assign...

On the theoretical limitations of joint inversion for basal slipperiness and effective viscosity in ice-flow models

Abstract. When modelling ice flows there are several aspects which are poorly constrained by observations, in particular parameters related to ice rheology and basal sliding. In computational ice flow models, inversion methods are frequently used to estimate the spatial distribut...

Mapping Global Pain and Trauma: A Seven-Domain Framework and the Fundamental Peace Index for the Journey from Shadow to Fundamental Peace

Background More than one billion people live with a mental health condition, roughly seven in ten adults experience at least one traumatic event in their lifetime, and about one in five people living in conflict-affected settings has a current mental disorder. Yet these figures d...

A multi-stage validation framework for trustworthy large-scale clinical information extraction using large language models

Abstract Large language models (LLMs) show promise for extracting clinically meaningful information from unstructured health records, yet real-world deployment is constrained by limited scalable, trustworthy validation approaches. Conventional evaluation relies on annotation-inte...

Bent optical waveguide finite element analysis with a 3D envelope Maxwell model

With the goal of accurately extracting the optical field losses in a three-dimensional (3D), circularly coiled waveguide (e.g., bent optical fiber), this effort presents the numerical methodologies that are implemented for an envelope Maxwell model that propagates electromagnetic...

Zero‐Waste Manufacturing of Ophthalmic Lenses by Direct Fluidic Shaping in Arbitrary Domains

ABSTRACT The conventional manufacturing of ophthalmic lenses is an inefficient subtractive process where up to 97% of the material is discarded through grinding, polishing, and edging. Fluidic Shaping has emerged as a powerful alternative, utilizing surface tension to form optica...

Temporal focusing enables distortion-resistant high-intensity spatiotemporal optical vortices

Spatiotemporal optical vortices (STOVs) carry transverse orbital angular momentum and offer new degrees of freedom for light-matter interactions. Yet conventional focusing techniques for STOVs introduce spatiotemporal imbalance between spatial diffraction and temporal dispersion,...

Scoring rules with normalized upper order statistics for tail inference

Abstract This paper proposes a scoring-rule-based method for ranking predictive distributions in the Fréchet domain that is able to distinguish between different tail indices. The approach is built on normalized order statistics and exploits proper scoring rules to compare tail l...

Generalized coulomb problem for a spin-1/2 fermion

We study the Dirac equation in 3+1 dimensions with a general combination of scalar, vector and tensor interactions with arbitrary strengths, all of them described by central Coulomb potentials acting on a particular plane of motion. For the tensor coupling a constant term is also...

Offshore Freshened Groundwater Distribution Is Controlled by Along‐ and Cross‐Shore Topographic Variability

Abstract Offshore Freshened Groundwater (OFG) reservoirs are regarded as a potentially significant resource stored in continental shelves. While the role of subsurface geological conditions in controlling OFG has been widely recognized, the influence of the topography of the host...

Audit and feedback interventions for recruitment and retention in clinical trials: A systematic review

BACKGROUND/AIMS: This study had two objectives: (1) to determine the effectiveness of audit and feedback interventions for improving recruitment and retention in randomised controlled trials (hereinafter referred to as trials) and (2) to identify and code behaviour change techniq...

Correlated inhomogeneous absorption profiles across distinct optical transitions in a rare-earth doped crystal

In rare-earth ion-doped crystals, inhomogeneous absorption profiles reflect the distribution of local environments experienced by individual ions. While each optical transition probes this distribution differently, their fine spectral structures may retain correlations arising fr...

W-Algebras of the Deligne–Cvitanović Exceptional Series and the Minimal 3d $$\mathcal {N}=4$$ SCFT

Abstract We propose a three-dimensional field theory construction that realizes the vertex algebras associated with the intermediate Lie algebras and the related $$C_2$$ C 2 -cofinite minimal W -algebras of the Deligne–Cvitanovi? (DC) series as boundary algebras. The construction...
