The 11th Dimensional super power man from the short story Lion's Tail
Dr. C.S. Lakshmi uses the pen name Ambai for publishing Tamil fiction. Ambai, a Sahitya Akademi Award winner in 2021, has written works with feminist themes. A skilled short story writer. It is only possible for a few writers to mix science and novel short stories. Embedding modern scientific theories in the short story, Ambay has created a short story called "Lion's Tail" without compromising his literary taste. This short story gives an understanding of the eleventh dimension related to physics theories such as the Theory of Everything, M Theory, and String Theory. Are we still alive after the death of Mr. Haror, a Germany-based Sri Lankan writer named Rajshiva, on Facebook in 2014? Ambai's narration has helped with the article posted under the title. This article was reposted the same year by Saravana Dev in the Ekara Tamil Repository. The earth we live on has three dimensions. Scientists like Einstein confirmed the fourth dimension of spacetime. His Theory of Everything was followed by String Theory and M Theory. Physicists believe that eleven dimensions are the final result of all these theories. They suggest that life may exist in this first dimension and that they may have different energies than humans living on Earth. A cyborg is a combination of man, animal, and machine. It can also be considered a ghost. The aim of the article is to show that the story of "Lion's Tail" is written with the hypothesis that a creature in the eleventh dimension might be like a cyborg. In this short story, concepts and details about the eleventh dimension, the nature of the creatures living there, and the morphology, character, and power of the character Achyuth, who is a cyborg, are explained. M theory and string theory rank as nominal theories. In this short story, concepts and details about the eleventh dimension, the nature of the creatures living there, and the characters are explored. The power of the character Achyut, who is a cyborg, is explained. M theory and string theory rank as nominal theories. Mythical characters inherit concepts of birth and death, and concepts of female space are also seen. The short story is an analogy that takes science and combines it with traditional ideas
Relationship between caries status (caries and caries free group), salivary flow rate, buffering capacity, salivary mutans streptococcus count and sugar intake among 3-5 year old preschool children
INTRODUCTION :
In a period marked by brilliant achievements in the prevention and
treatment of disease, dental caries still remains one of the most widespread
affliction in modern man. Dental caries is a slowly progressing disease that
manifests as a result of mineral imbalance between the tooth and the
environment. It is something of a paradox that teeth can be destroyed relatively
rapidly in vivo and are almost indestructible postmortem. While it is true that
diseases of teeth do not normally kill humans, they certainly affect the personâs
efficiency and they can, if neglected, provoke serious conditions elsewhere in
the body. Their contribution to the general fund of human misery is legendary.
The disease progression can be stopped if the factors responsible are
nullified in the initial stage. It is thus important to identify high caries risk
markers as well as individuals to implement preventive and interceptive
procedures.
Dental caries is a multifactorial disease in which there is interplay of
three principle factors; the host (primarily the saliva and teeth), the microflora,
and the substrate or diet. In evaluating the caries risk of a patient a number of
factors must be taken into consideration. Salivary counts of mutants
streptococcus combined with the measurement of salivary flow rate and buffer
effect and sugar consumption are frequently used for diagnostic and predictive
purpose in cariology.
AIMS AND OBJECTIVES :
1. To study the relation between caries status, salivary flow rate, salivary
buffering capacity, mutans streptococcus count, and sugar intake among
3-5 year old pre school children.
2. To correlate the frequency of sugar intake with caries experience of the
individual.
3. To determine the relation between salivary flow rate and salivary
buffering capacity with caries experience.
4. To compare the levels of s.mutans with the caries experience of the
individual.
5. To evaluate the relationship, if any between microbial parameter and
sugar index.
6. To evaluate the relationship, if any between microbial parameter and
salivary parameters.
7. To identify the caries risk group and to implement preventive strategies
on the primary dentition so as to prevent the transmission of an infection
from the primary to permanent dentition, subsequently interfering with
or delaying the occurrence of decay.
MATERIALS & METHODOLOGY :
The present study comprised of 100 healthy children in the age group of
3-5 years from local nursery schools in Chennai. All children were in the
primary dentition stage. A proforma was prepared to record the data.

these variables in 50 caries and 50 caries free, 3 â 5 years old preschool
children.
CONCLUSION :
The present study was undertaken in the local nursery schools of
Chennai among 3 â 5 year old preschool children to evaluate the sugar intake,
the microbial and nonmicrobial parameters and its relation with the caries
experience and if any interrelationship between these variables.
The following conclusion were drawn from the study:
1. There was a highly significant relation between frequency of sugar
consumption and caries experience. (P < 0.001)
2. There was a inverse relation between salivary parameters (salivary flow
rate, buffering capacity) and the caries experience. (P < 0.001)
3. There was a direct relation between microbial parameter (salivary
mutans streptococcus count) and the caries experience. (P < 0.001)
4. There was a strong relation between salivary parameters (salivary flow
rate, buffering capacity) and the streptococcus mutans count. (P < 0.001)
5. There was a weak relation between frequency of sugar consumption and
the streptococcus mutans count. (P = 0.07)
6. There was a direct relation between salivary flow rate and salivary
buffering capacity. (P < 0.001)
The need to search for risk indicators for dental caries in order to target
risk groups has been one of the subjects of a recent conference on the
assessment of risk group in dentistry. These parameters evaluated in the
current study could be used to discriminate highly infected subjects from non
infected subjects and therefore may be indicators of an increased or reduced
risk for dental decay. After an initial diagnosis of risk indicators, the high risk
groups are identified and therapy should be directed to preventive strategies
such as the use of fluorides, sealants and other antimicrobial supplements.
Further research is needed to identify the other possible risk indicators and its
relation with the caries experience
Intelligent Intrusion Detection System using Enhanced Arithmetic Optimization Algorithm with Deep Learning Model
The widespread use of interoperability and interconnectivity of computing systems is becoming indispensable for enhancing our day-to-day actions. The susceptibilities deem cyber-security systems necessary for assuming communication interchanges. Secure transmission needs security measures for combating the threats and required developments to security measures that counter evolving security risks. Though firewalls were devised to secure networks, in real-time they cannot detect intrusions. Hence, destructive cyber-attacks put forward severe security complexities, requiring reliable and adaptable intrusion detection systems (IDS) that could monitor unauthorized access, policy violations, and malicious activity practically. Conventional machine learning (ML) techniques were revealed for identifying data patterns and detecting cyber-attacks IDSs successfully. Currently, deep learning (DL) methods are useful for designing accurate and effective IDS methods. In this aspect, this study develops an intelligent IDS using enhanced arithmetic optimization algorithm with deep learning (IIDS-EAOADL) method. The presented IIDS-EAOADL model performs data standardization process to normalize the input data. Besides, equilibrium optimizer based feature selection (EOFS) approach is developed to elect an optimal subset of features. For intrusion detection, deep wavelet autoencoder (DWAE) classifier is applied. Since the proper tuning of parameters of the DWNN is highly important, EAOA algorithm is used to tune them. For assuring the simulation results of the IIDS-EAOADL technique, a widespread simulation analysis takes place using a benchmark dataset. The experimentation outcomes demonstrate the improvements of the IIDS-EAOADL model over other existing technique
Data Privacy and Security in Cloud Computing Environments
The globe has adopted the cloud computing environment, which organizes data and manages space for data storage, processing, and access. This technical development has brought up questions regarding data security and privacy in cloud computing environments, though. The purpose of this abstract is to offer a thorough review of the issues, solutions, and future developments related to data privacy and security in cloud computing. Keeping data private and secure while it is being processed and stored in outside data centres is the main difficulty in cloud computing systems. The abstract discusses the dangers of insider threats, data breaches, and illegal access to sensitive information. It digs further into the legal and compliance criteria that businesses must follow in order to protect user data in the cloud. In result, data privacy and security in cloud computing environments remain critical concerns for organizations and individuals alike. In the survey the overview of how to use cloud storage globally and its challenges, solution and future innovation is well explained. It underscores the importance of robust encryption, access controls, user awareness, and emerging technologies in safeguarding data in the cloud. By addressing these concerns, organizations can leverage the power of cloud computing while maintaining the confidentiality, integrity, and availability of their data
Masses of Multiquark Droplets
The mass formulae for finite lumps of strange quark matter with , and
quarks, and non-strange quark matter consisting of and quarks are
derived in a non-relativistic potential model. The finite-size effects
comprising the surface, curvature and even, the Gauss curvature were
consistently obtained, which shows a converging trend. It is found that there
is a possibility for the formation of metastable strangelets of large mass. The
model predicts low charge to mass ratio as the characteristic signature of
strange matter in agreement with the relativistic studies. This study also
yields an independent estimate for the bag energy density , which is in
agreement with the M.I.T bag model value.Comment: 24pages + 5 figures available upon request,Latex,IP/BBSR/93-3
Phosphoproteomics of retinoblastoma:A pilot study identifies aberrant kinases
Retinoblastoma is a malignant tumour of the retina which most often occurs in children. Earlier studies on retinoblastoma have concentrated on the identification of key players in the disease and have not provided information on activated/inhibited signalling pathways. The dysregulation of protein phosphorylation in cancer provides clues about the affected signalling cascades in cancer. Phosphoproteomics is an ideal tool for the study of phosphorylation changes in proteins. Hence, global phosphoproteomics of retinoblastoma (RB) was carried out to identify signalling events associated with this cancer. Over 350 proteins showed differential phosphorylation in RB compared to control retina. Our study identified stress response proteins to be hyperphosphorylated in RB which included H2A histone family member X (H2AFX) and sirtuin 1. In particular, Ser140 of H2AFX also known as gamma-H2AX was found to be hyperphosphorylated in retinoblastoma, which indicated the activation of DNA damage response pathways. We also observed the activation of anti-apoptosis in retinoblastoma compared to control. These observations showed the activation of survival pathways in retinoblastoma. The identification of hyperphosphorylated protein kinases including Bromodomain containing 4 (BRD4), Lysine deficient protein kinase 1 (WNK1), and Cyclin-dependent kinase 1 (CDK1) in RB opens new avenues for the treatment of RB. These kinases can be considered as probable therapeutic targets for RB, as small-molecule inhibitors for some of these kinases are already in clinical trials for the treatment other cancers
Transverse momentum dependence of directed particle flow at 160 AGeV
The transverse momentum () dependence of hadron flow at SPS energies is
studied. In particular, the nucleon and pion flow in S+S and Pb+Pb collisions
at 160 AGeV is investigated. For simulations the microscopic quark-gluon string
model (QGSM) is applied. It is found that the directed flow of pions changes sign from a negative slope in the low- region to a
positive slope at GeV/c as recently also observed
experimentally. The change of the flow behaviour can be explained by early
emission times for high- pions. We further found that a substantial amount
of high- pions are produced in the very first primary NN collisions at the
surface region of the touching nuclei. Thus, at SPS energies high-
nucleons seem to be a better probe for the hot and dense early phase of nuclear
collisions than high- pions. Both, in the light and in the heavy system
the pion directed flow exhibits large negative values when
the transverse momentum approaches zero, as also seen experimentally in Pb+Pb
collisions. It is found that this effect is caused by nuclear shadowing. The
proton flow, in contrary, shows the typical linear increase with rising .Comment: REVTEX, 20 pages incl. 6 figures, revised and extended versio
Pair-Hopping Mechanism for Layered Superconductors
We propose a possible charge fluctuation effect expected in layered
superconducting materials. In the multireference density functional theory,
relevant fluctuation channels for the Josephson coupling between
superconducting layers include the interlayer pair hopping derived from the
Coulomb repulsion. When interlayer single-electron tunneling processes are
irrelevant in the Kohn-Sham electronic band structure calculation, the two-body
effective interactions stabilize a superconducting phase. This state is also
regarded as a valence-bond solid in a bulk electronic state. The hidden order
parameters coexist with the superconducting order parameter when the charging
effect of a layer is comparable to the pair hopping. Relevant materials
structures favorable for the pair-hopping mechanism are discussed.Comment: 24 pages, 2 figures, to be published in J. Phys. Soc. Jpn. (2009
Dilepton production in heavy ion collisions at intermediate energies
We present a unified description of the vector meson and dilepton production
in elementary and in heavy ion reactions. The production of vector mesons
() is described via the excitation of nuclear resonances ().
The theoretical framework is an extended vector meson dominance model (eVMD).
The treatment of the resonance decays with arbitrary spin is
covariant and kinematically complete. The eVMD includes thereby excited vector
meson states in the transition form factors. This ensures correct asymptotics
and provides a unified description of photonic and mesonic decays. The
resonance model is successfully applied to the production in
reactions. The same model is applied to the dilepton production in elementary
reactions (). Corresponding data are well reproduced. However, when
the model is applied to heavy ion reactions in the BEVALAC/SIS energy range the
experimental dilepton spectra measured by the DLS Collaboration are
significantly underestimated at small invariant masses. As a possible solution
of this problem the destruction of quantum interference in a dense medium is
discussed. A decoherent emission through vector mesons decays enhances the
corresponding dilepton yield in heavy ion reactions. In the vicinity of the
-peak the reproduction of the data requires further a substantial
collisional broadening of the and in particular of the meson.Comment: 32 pages revtex, 19 figures, to appear in PR
