A Menon-type identity using Klee's function
No full textsummary:Menon's identity is a classical identity involving gcd sums and the Euler totient function . A natural generalization of is the Klee's function . We derive a Menon-type identity using Klee's function and a generalization of the gcd function. This identity generalizes an identity given by Y. Li and D. Kim (2017)
Equivariant elliptic cohomology and twisted equivariant k-theory
No full textEquivariant elliptic cohomology and twisted equivariant K-theory are both related to the representations of loop groups. After making these relationships precise, we propose a map from twisted equivariant elliptic cohomology to twisted K-theory of the inertia stack using equivariant de Rham models. This proposal agrees with the Freed-Hopkins-Teleman q = 1 map from characters of representations of loop groups to distributions associated to twisted equivariant K-theory classes.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2021-08-01The student, Dileep Menon, accepted the attached license on 2019-05-24 at 15:54.The student, Dileep Menon, submitted this Dissertation for approval on 2019-05-24 at 16:06.This Dissertation was approved for publication on 2019-05-28 at 10:50.DSpace SAF Submission Ingestion Package generated from Vireo submission #13991 on 2019-11-26 at 13:00:58Made available in DSpace on 2019-11-26T20:49:00Z (GMT).

Plat. Men. 70a-b: Menon
No full textIn diesem Dialog des Sokrates mit Menon ist das zentrale Thema, ob etwas erlernbar, übbar oder von Natur aus vorhanden ist. Dies wird v. a. anhand der Areté erörtert, wobei das Zitat den Ausgangspunkt darstellt. Die Thessalier werden hier als ob ihres Reichtums, ihrer Reitkunst und ihrer Weisheit bekannt gezeigt. Die Charakterisierung der Thessaler als gute Reiter findet sich in der antiken Literatur des Öfteren (vgl. u. a. Plat. Hipp. mai. 284a; Plat. leg. 625c-d.). Xen. Hell. 6,1,9-10 und Diod. 15,85,4-5 gelten sie zudem als talentierte Speerwerfer
A class of Siamese twin Menon designs
No full textA{0,±1}-matrix S is called a Siamese twin design
sharing the entries of I, if S = I + K − L, where I, K, L are non-zero
{0, 1}-matrices and both I + K and I + L are incidence matrices of
symmetric designs with the same parameters. Let p and 2p−1 be prime powers and p ≡ 3 (mod 4). We describe a construction of a Siamese twin Menon design with parameters (4p², 2p² −p, p² −p), yielding a Siamese twin Hadamard design with parameters (4p ²− 1, 2p ²− 1, p² − 1)
Preliminary results on the empirical applicability of the Tsallis distribution in elastic hadron scattering
No full textFundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)We show that the proton-proton elastic differential cross section data at dip position and beyond can be quite well described by a parametrization based on the Tsallis distribution, with only five free fit parameters. Extrapolation of the results obtained at 7 TeV to large momentum transfer, suggests that hadrons may not behave as a black-disk at the asymptotic energy region. © 2013 American Institute of Physics.1520300302CNPq,CAPES,CLAF,FAPESP,FAPERJFundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Kašpar, J., Kundrát, V., Lokajíček, M., Procházka, J., (2011) Nucl.

MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
Service-sector competition, innovation and R&D
No full textThe central prediction of the Aghion et al. (2005) model is an inverted U-shaped relation between innovation and competition. The model is built on the assumption of a product market and has not yet been empirically tested on service-sector firms. Using detailed firm-level data, we find the inverse U-shaped relation to hold for both small and large service-sector firms. However, non-exporting service firms deviate from the overall pattern. A more detailed breakdown of innovation expenditures shows that the inverse U-shaped pattern holds for both intramural R&D and training, but not for extramural R&D. Finally, as competition increases, small firms tend to seek more strategic alliances with competitors while large firms tend to decrease their collaboration with competitors. To some extent, the behavior of large firms can be due to their greater capacity to handle innovation projects internally and as competition increases, so does the payoff of an edge to competitors.R&D; innovation; competition; service sector
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
D-Fence layer: an ensemble framework for comprehensive deepfake detection
No full textThe rapid advancement of deep learning and computer vision technologies has given rise to a concerning class of deceptive media, commonly known as deepfakes. This paper addresses emerging trends in deepfakes, including the creation of hyper-realistic facial manipulations, the incorporation of synthesized human voices, and the addition of fabricated subtitles to video content. To effectively combat these multifaceted deepfake threats, we introduce an ensemble-based deepfake detection framework called the “D-Fence” layer. The D-Fence layer consists of two uni-modal classifiers designed to identify tampered facial and vocal elements, as well as two cross-modal classifiers for interactions between Video-Audio and Audio-Text domains to detect deepfakes across multiple modalities. To evaluate the effectiveness of our framework, we introduce two novel adversarial attacks: the “Bogus-in-the-middle” attack, which strategically inserts counterfeit video frames within authentic sequences, and the “Downsampling attack”, designed to create deceptive audio. A comparative study of the D-Fence layer against various state-of-the-art multi-modal deepfake detection systems is conducted, demonstrating that our ensemble architecture outperforms existing classifiers. Under diverse adversarial conditions, our D-Fence layer achieves an impressive detection accuracy of 92%, showcasing its ability to detect deepfakes efficiently and reliably
