Generalized Fock Spaces and New Forms of Quantum Statistics
The recent discoveries of new forms of quantum statistics require a close
look at the under-lying Fock space structure. This exercise becomes all the
more important in order to provide a general classification scheme for various
forms of statistics, and establish interconnections among them whenever it is
possible. We formulate a theory of generalized Fock spaces, which has a three
tired structure consisting of Fock space, statistics and algebra. This general
formalism unifies various forms of statistics and algebras, which were earlier
considered to describe different systems. Besides, the formalism allows us to
construct many new kinds of quantum statistics and the associated algebras of
creation and destruction operators. Some of these are: orthostatistics, null
statistics or statistics of frozen order, quantum group based statistics and
its many avatars, and `doubly-infinite' statistics. The emergence of new forms
of quantum statistics for particles interacting with singular potential is also
highlighted.Comment: 9 pages, LaTex, Appeared in Spin-Statistics Connection and

Fock Space Representation of Differential Calculus on the Noncommutative Quantum Space
A complete Fock space representation of the covariant differential calculus
on quantum space is constructed. The consistency criteria for the ensuing
algebraic structure, mapping to the canonical fermions and bosons and the
consequences of the new algebra for the statistics of quanta are analyzed and
discussed. The concept of statistical transmutation between bosons and fermions
is introduced
M\"{o}ller and Bhabha scattering in the noncommutative standard model
We study the M\"{o}ller and Bhabha scattering in the noncommutative extension
of the standard model(SM) using the Seiberg-Witten maps of this to first order
of the noncommutative parameter . We look at the angular
distribution to explore the noncommutativity of space-time at
around TeV and find that the distribution deviates
significantly from the one obtained from the commutative version of the
standard model.Comment: 15 pages, 14 eps figures.Text is modified a little and version to

Innovative Teaching and Learning
The biggest challenge any teacher faces is capturing the students’ attention, and putting across ideas in such a way that it stays with them long after they have left the classroom. For this to happen, classroom experience should be redefined and innovative ideas that make teaching learning methods more effective should be implemented. So here are some innovative ideas that will help teachers reinvent their teaching methods and make their classes interesting. The use of innovative methods in educational institutions has the potential not only to improve education, but also to empower people, strengthen governance and galvanize the effort to achieve the human development goal for the country. The purpose of this paper is to suggest useful innovative teaching methods which could easily be imparted knowledge to the students
Anthropocentrism in the Select American Dystopic Fictions: The Water Knife by Paolo Bacigalupi and Claire Vaye Watkins’ Gold Fame Citrus
A conductive environment is the most crucial thing for any living being to lead life happily in the world. The environment includes both biotic and abiotic components. At present, people are facing more problems due to environmental issues. This research paper aims to see anthropocentrism through the interaction between humans and the environment in the select American dystopic fictions The Water Knife by Paolo Bacigalupi and Gold Fame Citrus by Claire Vaye Watkins. These novels' major themes deal with climate change, water shortage, drought, and other ecological crises. In this research, a qualitative approach has been taken up as a method. The result of the study reveals that humans have more responsibilities to protect water bodies and the environment. People need to follow ethics effectively and not be involved in anthropocentric activities to come out of water shortages. The study reminds us that nature is more powerful than man
THE LIMITATIONS OF NORMATIVE ETHICS: ANTHROPOCENTRISM IN KIM STANLEY ROBINSON’S 2312
Purpose of the study: The present study mainly argues the limitations of normative ethics and analyzes the anthropocentrism in Kim Stanley Robinson’s 2312 based on the actions or duties of the characters.
Methodology: The article used normative ethics as a methodology. Normative ethics is the study of ethical actions that has certain rules and regulations about how we ought to do and decide. So, this study has chosen a normative ethic that consists of three ethical theories Utilitarian approach, Kantian ethics and Virtue ethics to judge duties that are right and wrong.
Main Findings: As a result, normative ethics compact with a one-dimensional approach. All three ethics deal with its own specific code of ethics. Utilitarianism has focused on good outcomes. Kantian ethics has paid attention to good rules with duty. Virtue ethics focused on the good people but all three theories have a strong common objective of focusing on only human beings (sentient entities) and omit other entities (plants and animals). So all normative ethics have certain limitations and do their duties without thinking about consequences and situations. In conclusion, this code of normative ethics has provoked as anthropocentric. In addition that Swan’s actions and the rational behavior made her miserably failed in Mercury through the construction of the biome and creation of quantum computers. So this cause, in the end, the space people want to move from space to earth to rebuild the biome.
Applications of this study: The prudent study analyses the normative ethics in a detailed manner under the Utilitarian approach, Kantian ethics and Virtue ethics. These philosophical domains can be benefitted for researchers to practice and implement during the research process in Humanities and Social Sciences especially.
Novelty/Originality of this study: The study analyzed the anthropocentric attitude of the character Swan in 2312 based on her actions or duties through the code of normative ethics (Utilitarianism, Kantian ethics and Virtue ethics)
Threshold Effects on Quasi-degenerate Neutrinos with High-scale Mixing Unification
We consider threshold effects on neutrino masses and mixings in a recently
proposed model for understanding large solar and atmospheric mixing angles
using radiative magnification for the case of quasi-degenerate neutrinos. We
show that the magnitude of the threshold effects is sufficient to bring
concordance between the predictions of this model and latest data from and on observations of neutrino oscillations.Comment: Four pages, no figure
Somatic embryo formation by cultured ovules of Cabernet Sauvignon grape: Effects of fertilization and of the male gameticide toluidine blue
Maximum numbers of pollen tubes were found in styles of plants growing at 27 °C (day) and 22 °C (night). Fertilization generally occurred by 24 h after anthesis. Treatment of both isolated pollen and inflorescences of intact vines with toluidine blue (10-100mg l-1) reduced pollen germination and tube growth. Pollen tubes which penetrated the styles of toluidine blue-treated flowers appeared to be abnormal. Somatic embryos were produced with equal frequency by nucellus tissue from cultured ovules from both normally-fertilized and toluidine blue-treated flowers. There was degeneration of embryosacs in all cultured ovules. The grape appears to be unresponsive to toluidine blue as an inducer of haploid parthenogenesis
