A (1.999999)-approximation ratio for vertex cover problem
Majid Zohrehbandian
The vertex cover problem is a famous combinatorial problem, and its complexity has been heavily studied. While a 2-approximation can be trivially obtained for it, researchers have…
RLAS-BIABC: A Reinforcement Learning-Based Answer Selection Using the BERT Model Boosted by an Improved ABC Algorithm
Hamid Gharagozlou, Javad Mohammadzadeh, Azam Bastanfard +1
Answer selection (AS) is a critical subtask of the open-domain question answering (QA) problem. The present paper proposes a method called RLAS-BIABC for AS, which is established o…
Electron Attachment and Electron Ionization of Helium Droplets Containing Clusters of C60 and Formic Acid
Masoomeh Mahmoodi-Darian, Elias Jabbour Al Maalouf, Samuel Zöttl +2
High-resolution mass spectra of helium droplets doped with C and formic acid (FA) are ionized by electrons. Positive ion mass spectra reveal cluster ions [(C)FA$_…
Solvation of Silver Ions in Noble Gases He, Ne, Ar, Kr, and Xe
Masoomeh Mahmoodi-Darian, Paul Martini, Lukas Tiefenthaler +3
We use a novel technique to solvate silver cations in small clusters of noble gases. The technique involves formation of large, superfluid helium nanodroplets that are subsequently…
Phosphorus cluster cations formed in doped helium nanodroplets are different
Simon Albertini, Faro Hechenberger, Siegfried Kollotzek +8
Positively charged cluster ions of phosphorus were formed upon electron ionization of doped helium nanodroplets. The vapors of red phosphorus and a phosphate sample were picked up…
A Method for Numerical Solution of Third-Kind Volterra Integral Equations Using Krall-Laguerre Polynomials
P. Jami, E. Hashemizadeh
The present study proposed a method for numerical solution of linear Volterra integral equations (VIEs) of the third kind, before only analytical solution methods had been discusse…
