Efektivitas Penyuluhan Rabun Jauh (Miopia) Terhadap Tingkat Pengetahuan Siswa Kelas VI SD Islam Al-azhar 21 Kecamatan Pontianak Tenggara Tahun 2014 [PDF]

open access: yes, 2014
Background: Visual acuity is the primary indicator for healthy eye. Visual acuity will decrease if there is a process that impaires reflective media in the eye. Myopia is a type of refractive disorders that is common in school-age population.

New Policies Exploiting Randomness of Lead Times in Inventory Systems

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT Recent research provided proof‐of‐concept that the randomness of lead times in inventory systems can be exploited to achieve large—potentially unlimited—performance improvements, compared to the case of constant lead time. Specifically, the Generalized Base Stock (GBS) policy serves as such proof‐of‐concept—it can deliver unlimited ...

A Cost Function Approximation Based Large Neighborhood Search for Dynamic Medical Courier Services

open access: yesNetworks, EarlyView.
ABSTRACT Medical on‐demand couriers play an important role in urban medical services. They transport medical supplies, tests, blood, or organs between different locations in the city within a short amount of time. Transportation orders are issued spontaneously and differ in their priority and time restrictions. Since all orders must be served, the goal

Mixed‐Integer Linear Programming Approaches for Nested p$$ p $$‐Center Problems With Absolute and Relative Regret Objectives

open access: yesNetworks, EarlyView.
ABSTRACT We introduce the nested p$$ p $$‐center problem, a multi‐period variant of the well‐known p$$ p $$‐center problem. Using the nesting concept allows us to obtain solutions consistent over the considered time horizon, that is, facilities that are opened in a given time period stay open for subsequent periods.

Yield of Whole Genome Sequencing for Pathogenic Single Nucleotide Variants in Congenital Heart Disease: A Systematic Review and Meta‐Analysis

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT Objective This systematic review and meta‐analysis aimed to assess the diagnostic yield of pathogenic or likely pathogenic (P/LP) single nucleotide variants (SNVs) using whole genome sequencing (WGS) in congenital heart disease (CHD). Methods A systematic search of three databases (2000–2024) was conducted, and two reviewers independently ...

Insights into shape of uveal melanoma: a comprehensive evaluation of clinical features, pathological features, and prognosis analysis

open access: yesFrontiers in Medicine
BackgroundMany patients with uveal melanoma (UM) cannot receive laboratory analysis due to eye-preserving treatment, biopsy risks or costs. The study is to evaluate correlation between tumor shape and a series of metastasis risks in UM, and to assess the

Mapping Thermal Conductivity at the Atomic Scale: A Step toward the Thermal Design of Materials

open access: yesphysica status solidi (b), EarlyView.
The site‐projected thermal conductivity method resolves the local thermal conduction contribution per atom by decomposing the Green–Kubo thermal conductivity tensor under the harmonic approximation. It highlights thermally active sites and “thermal defects” within disordered or amorphous materials, enabling spatially resolved insights into atomic‐scale
