Fraud Detection using Machine Learning in the Mobile Payment Service
The transformation of payment mechanism from face-to-face transactions to non-face-to-face transactions has led to increased popularity of Internet Banking, credit card, online billing in the mobile phone itself and, hence, it is directly proportional to the advancement of smartphones in particular. However, the probability of any kind of anomalous payments increases and due to that the requirement of fraud detection arises. This paper provides the idea of the trend followed in the detection of fraud in online payment through mobile phone with the help of machine learning [1]
5-dim Superconformal Index with Enhanced En Global Symmetry
The five-dimensional supersymmetric gauge theory with Sp(N)
gauge group and SO(2N_f) flavor symmetry describes the physics on N D4-branes
with D8-branes on top of a single O8 orientifold plane in Type I' theory.
This theory is known to be superconformal at the strong coupling limit with the
enhanced global symmetry for . In this work we calculate
the superconformal index on for the Sp(1) gauge theory by the
localization method and confirm such enhancement of the global symmetry at the
superconformal limit for to a few leading orders in the chemical
potential. Both perturbative and (anti)instanton contributions are present in
this calculation. For cases some issues related the pole structure of
the instanton calculation could not be resolved and here we could provide only
some suggestive answer for the leading contributions to the index. For the
Sp(N) case, similar issues related to the pole structure appear.Comment: 70 pages, references added, published versio
Modeling and Simulation of PV Panel Under Different Internal and Environmental Conditions with Non-constant Load
This paper focuses on PV power conversion under different internal and environmental conditions with non-constant load, connected to a smart grid system. Due to environmental conditions, the PV system is a non-linear system and difficult to predict the power conversion. In the aspect of internal variables, it includes the five parameters of the single diode solar cell model identify their sensitivity through error function. It also identifies the relation between environmental conditions, mainly: irradiance, temperature and wind speed. The modeling and computational simulation with laboratory work identify the effects of internal and environmental effect on the system. The model gives details about the sensitivity of each environmental condition using error function. The work includes the decrease of energy conversion by the solar panel as a function of time due to the shadow effect that affects its performance. Besides these, a smart system is introduced as a DAQ system in laboratory environment to get in real time the power conversion value with the P-V and I-V characteristics of the PV panel
M5-branes from gauge theories on the 5-sphere
We use the 5-sphere partition functions of supersymmetric Yang-Mills theories
to explore the (2,0) superconformal theory on S^5 x S^1. The 5d theories can be
regarded as Scherk-Schwarz reductions of the 6d theory along the circle. In a
special limit, the perturbative partition function takes the form of the
Chern-Simons partition function on S^3. With a simple non-perturbative
completion, it becomes a 6d index which captures the degeneracy of a sector of
BPS states as well as the index version of the vacuum Casimir energy. The
Casimir energy exhibits the N^3 scaling at large N. The large N index for U(N)
gauge group also completely agrees with the supergravity index on AdS_7 x S^4.Comment: 44 pages, 1 figure, v4: ref added, clarified weak/strong coupling

Role of Herbal Medicine in Cardiovascular Activities
Herbal medicine has gained substantial attention for its potential role in supporting cardiovascular health. This chapter explores the intricate interplay between herbal compounds and cardiovascular activities, shedding light on their mechanisms of action and therapeutic applications. With a historical backdrop of traditional herbal medicine, the prevalence of cardiovascular diseases serves as a compelling backdrop for the investigation. The chapter delves into the multifaceted mechanisms by which herbal compounds influence the cardiovascular system. Notably, herbs exhibit vasodilatory effects, contributing to blood pressure regulation, and harbor potent antioxidant and anti-inflammatory properties that collectively mitigate oxidative stress and inflammation within the cardiovascular milieu. Furthermore, certain herbs intricately modulate lipid metabolism, holding promise in the management of dyslipidemia. A thorough analysis of well-known herbal treatments clarifies each one's unique contributions to cardiovascular health. Hawthorn is revealed to be the champion of heart health, and garlic demonstrates its mastery of cholesterol reduction. Ginkgo Biloba is notable for its capacity to improve circulation, and turmeric demonstrates powerful anti-inflammatory properties. The chapter also looks at herbal medicine's potential as an intervention for regulating fluid balance, arrhythmias, and hypertension. Examined is the potential for resveratrol-rich plants and green tea to protect against heart disease. Along with considerations for safety, interactions, and future study, the symbiotic relationship between stress reduction, adaptogenic herbs, and heart health is also discussed in this article. This chapter concludes with a thorough examination of the crucial part herbal medicine plays in cardiovascular health. The complex interaction between herbal substances and circulatory functions, from mechanisms of action to clinical applications, shows promise for a more integrative and holistic approach to cardiovascular car
On instantons as Kaluza-Klein modes of M5-branes
Instantons and W-bosons in 5d maximally supersymmetric Yang-Mills theory
arise from a circle compactification of the 6d (2,0) theory as Kaluza-Klein
modes and winding self-dual strings, respectively. We study an index which
counts BPS instantons with electric charges in Coulomb and symmetric phases. We
first prove the existence of unique threshold bound state of (noncommutative)
U(1) instantons for any instanton number, and also show that charged instantons
in the Coulomb phase correctly give the degeneracy of SU(2) self-dual strings.
By studying SU(N) self-dual strings in the Coulomb phase, we find novel
momentum-carrying degrees on the worldsheet. The total number of these degrees
equals the anomaly coefficient of SU(N) (2,0) theory. We finally show that our
index can be used to study the symmetric phase of this theory, and provide an
interpretation as the superconformal index of the sigma model on instanton
moduli space.Comment: 54 pages, 2 figures. v2: references added, figure improved, added
comments on self-dual string anomaly, added new materials on the symmetric
phase index, other minor correction
