Towards Characterization of Five‐List‐Colorability of Toroidal Graphs

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT Through computer‐assisted enumeration, we list minimal obstructions for 5‐choosability of graphs on the torus with the following additional property: There exists a cyclic system of non‐contractible triangles around the torus where the consecutive triangles are at distance at most four.

Dipole‐Quadrupole Model and Multipole Analysis of Resonant Membrane Metasurfaces

open access: yesLaser &Photonics Reviews, EarlyView.
Membrane metasurfaces, arrays of holes in a dielectric membrane, are appealing because they require no substrate and allow access to resonant near‐fields. However, developing a comprehensive theoretical description for them remains challenging. We introduce a semi‐analytical dipole‐quadrupole approach to analyze their resonant spectra at arbitrary ...

Sonified Signals From a Compact FT‐ICR Instrument: A Feasibility Study. I—Data Mapping to an Equal‐Tempered Chromatic Scale

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Ions trapped within a Penning cell (ICR) travel periodic orbits whose frequencies are dependent on their mass‐to‐charge ratio and the value of the magnetic field passing through the trap. Fourier transformation (FT‐ICR) decomposes the signal induced in the detection circuit by the rotation of the ions in the cell after the ...

Optimal Placement of Grid Battery Energy Storage Systems for Congestion Mitigation and Enhanced Power‐Flow Control Considering Uncertainties in Photovoltaic Deployment

open access: yesIEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
Amidst the global drive toward carbon neutrality, the integration of large‐scale photovoltaic (PV) systems introduces significant challenges related to grid congestion. Battery energy storage systems (BESSs) are increasingly recognized as an effective solution for addressing these challenges and improving grid operations, especially under the ...

Color Energy Of A Unitary Cayley Graph

open access: yesDiscussiones Mathematicae Graph Theory, 2014
Let G be a vertex colored graph. The minimum number χ(G) of colors needed for coloring of a graph G is called the chromatic number. Recently, Adiga et al.

Prenatal 17‐Alpha‐Hydroxyprogesterone Caproate Exposure in Twins and Childhood Outcomes: 14‐Year Follow‐Up of a Randomised Trial

open access: yesBJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Objective Long‐term child outcomes after intra‐uterine exposure to 17‐alpha‐hydroxyprogesterone caproate (17‐OHPC) versus placebo. Design Follow‐up of the AMPHIA randomised controlled trial assessing neonatal outcomes after weekly 17‐OHPC injections compared to placebo in multiple pregnancies. Setting Multicentre.

Health Economic Evaluation of Varicella Vaccination Within the Swedish National Vaccination Programme for Children

open access: yesActa Paediatrica, EarlyView.
ABSTRACT Aim To assess the cost‐effectiveness of including varicella vaccination in the Swedish national vaccination programme for children together with the added impact of catch‐up vaccination of susceptible older children. Methods An epidemiological transmission model was used to assess the cost‐effectiveness of a two‐dose national varicella ...

Beyond performance: Emotions before and after semi‐high‐stakes mathematics testing among school‐aged students

open access: yesBritish Journal of Educational Psychology, EarlyView.
Abstract Background Previous research has shown that testing differs significantly from other classroom activities and is associated with heightened negative emotions and lower levels of positive emotions. However, relatively little is known about students' emotions surrounding testing, particularly in higher‐stakes assessment settings. Aims This study

An effective and efficient matheuristic for the electric vehicle routing problem with capacitated recharging stations

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract In this paper, we address the problem of routing a fleet of electric vehicles (EVs) to serve a set of customers, geographically distributed, within their time windows. We assume that EVs may also be recharged en route, and the amount of energy recharged at a recharging station (RS) is a decision variable itself, that is, partial recharges are ...
