Animalia Humorosum: Aesop's animal fables made more believable with a modern twist
No full textThere is much that is unusual about this 8½” square booklet of 28 pages followed by two pages of advertisements for other books by Óla. For starters, the pages are purple with light-colored typeface and cutout colored characters in partial-page illustrations. The T of C uses superscript to indicate page numbers for the twelve fables. That same page clarifies that Ólafia L. Óla is a pseudonym for V. Subhash. In TH, the hare, not the tortoise, challenges to a race upon no provocation. The author turns this tale into the more usual “Rabbit Races the Hedgehog,” famous among Grimm’s fairytales. Every one of the species looks the same to the superficial hare. In LM, after the mouse frees the lion, the hungry lion eats the mouse. “Steer clear of known dangers.” DW is told just as in the tradition. “Better die on your feet than live on your knees.” In TB, the second traveler takes off his socks; the smell of them revolts the bear, who departs. What did the bear whisper to him? “Tell that fellow that trees offer no safety because bears are good climbers.” The ox makes up a snake friend to worry the dog out of his manger. A passing hunter saves the shepherd boy attacked by a real wolf. The mice do manage to get a bell around the cat’s neck by having it ready around their hole when the cat pokes in its head. Two foxes jump for grapes. One reacts according to the tradition. The other says the effort has been stupid. “We are foxes. We don’t eat grapes. Let’s go and catch some rabbits.” One of two crows suggests the traditional pebble approach. The other says that will take too much time and too many pebbles and will dirty the water. He manages to knock over the pitcher and they can drink both from the water spilled and the water still in the overturned pitcher. The owner of the golden goose eventually stops reading his mail, misses paying taxes, loses his property, and has to give up the goose as compensation for the unpaid taxes. The wolf escapes the lambskin and never comes back. The crow removes the doughnut from his mouth and tells the fox to move along.Ólafia L. Óla (V. Subhash

No full textAlmost Polynomial Factor Inapproximability for Parameterized k-Clique
No full textThe k-Clique problem is a canonical hard problem in parameterized complexity.
In this paper, we study the parameterized complexity of approximating the
k-Clique problem where an integer k and a graph G on n vertices are given as
input, and the goal is to find a clique of size at least k/F(k) whenever the
graph G has a clique of size k. When such an algorithm runs in time T(k)poly(n)
(i.e., FPT-time) for some computable function T, it is said to be an
F(k)-FPT-approximation algorithm for the k-Clique problem.
Although, the non-existence of an F(k)-FPT-approximation algorithm for any
computable sublinear function F is known under gap-ETH [Chalermsook et al.,
FOCS 2017], it has remained a long standing open problem to prove the same
inapproximability result under the more standard and weaker assumption,
W[1]FPT.
In a recent breakthrough, Lin [STOC 2021] ruled out constant factor (i.e.,
F(k)=O(1)) FPT-approximation algorithms under W[1]FPT. In this paper, we
improve this inapproximability result (under the same assumption) to rule out
every factor FPT-approximation algorithm for any increasing
computable function H (for example ).
Our main technical contribution is introducing list decoding of Hadamard
codes over large prime fields into the proof framework of Lin
Analysis of conduction-radiation heat transfer in a 2D enclosure using the Lattice boltzmann method
No full textApplication of the lattice Boltzmann method (LBM) recently extended by Asinari et al. [P. Asinari, S. C. Mishra, and R. Borchiellini, A Lattice Boltzmann Formulation to the Analysis of Radiative Heat Transfer Problems in a Participating Medium, Numer. Heat Transfer B, 57(2), 126-146, 2010] for calculation of volumetric radiative information is extended for the analysis of a combined mode transient conduction and radiation heat transfer in a 2D rectangular enclosure containing an absorbing, emitting and scattering medium. Unlike all previous studies, with volumetric radiative information computed using the proposed LBM, the energy equation is formulated and solved using the LBM. In the combined mode conduction-radiation problem, to assess the computational advantage of computing the radiative information too using the LBM, the same problem is also solved using the LBM-finite volume method (FVM) formulation. In this LBM-FVM formulation, the FVM is used to calculate the volumetric radiative information needed for the energy equation, and the energy equation is solved using the LBM. Comparisons are made for the effects of the extinction coefficient, the scattering albedo and the conduction-radiation parameter on the temperature distributions in the medium. Although the number of iterations for the converged solution in LBM-LBM is much more than that of the LBM-FVM, computationally, the LBM-LBM is faster than the LBM-FV

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
