" Dark Matter & its Detection: Indian Initiative "


Dark Matter : Why and What?
Prof. Pijushpani Bhattacharjee
SINP, Kolkata

Abstract: A variety of astronomical observations over the past several decades have firmly established that there exist large discrepancies between the dynamical estimates of the amount of gravitating mass in the Universe based on the usual Newton/Einstein dynamics and the amount of observed "visible" mass in the Universe. This so-called mass discrepancy (MD) exists on all astronomical length scales ranging from (sub)galactic scales all the way up to the largest scale structures seen in the Universe today. The universal cosmological average density of the visible matter can account for only about 15% of the total density of gravitating matter estimated form dynamical considerations. Independent cosmological observations and arguments provide strong reasons to believe that this additional invisible gravitating mass cannot be composed of normal baryonic matter (protons, neutrons) that all known matter is composed of. The most popular resolution of this MD problem hinges on the hypothesis of existence of "Dark Matter", a new form of matter that is electromagnetically inert (hence invisible) and permeates throughout the Universe. The physical nature of the constituent(s) of this hypothetical Dark Matter (DM), however, remains unknown till date. There exist a large number of ideas and suggestions as to the possible composition of the DM, all essentially based on new physics beyond the Standard Model of fundamental particle physics. In addition, alternative explanation of the MD problem in terms of the so-called MOdified Newtonian Dynamics (MOND) (without the need for any DM) has also been suggested. In this talk we review the MD problem, the DM hypothesis and various suggested candidates of DM, and the basic ideas behind worldwide efforts towards detection of some of the suggested candidates of DM in laboratory experiments. Finally, we shall briefly discuss the basic ideas behind and issues with the MOND hypothesis of resolution of the MD problem.


Detectors and Detection Techniques for possible Dark Matter Search Experiment in India
Prof. Satyajit Saha
SINP, Kolkata

Abstract:Existence of Dark Matter (or the absence of it) has been an enigma that has puzzled the scientific community for quite some time. Many terrestrial experiments are going on searching for dark matter in the laboratory-based experiments. We have initiated our work towards setting up a dark matter search experiment at an underground location in India. Some of the experimental details, feasibility studies, radiation background survey and developmental work towards the experiment will be discussed in this talk.

"Brain-Computer Interface (BCI)"


Mind Controlled Robots - A Science or A Myth
Prof. Amit Konar
Department of Electronics & Telecommunication, Jadavpur University

Abstract: The presentation would begin with a discussion on the brain response to external stimulation with an aim to decode subject's perceptual ability and motor-intentions to control external actuating devices. The later part of the presentation would deal with hybrid brain-computer interfacing, where two or more brain signals would be used to control a robot by brain commanded signals. The application areas to be covered include rehabilitative robotic limbs for people with neuro-motor disability, cognitive failure detection in driving, bypassing damaged brain lobes by artificial means, and many others.


BCI Technology and its Ethical Implications
Amita Chatterjee
Emeritus Professor, School of Cognitive Science, Jadavpur University

Abstract:BCI, short for Brain Computer Interface, Technology is the most potential technology of the twenty first century where science fictions seem to have come true. Put simplistically, BCI is a form of technology which uses brain signals to control devices in the external world. Both invasive and non-invasive forms of BCI have therapeutic and enhancement uses. With advancement in technology and commercialization of BCI products a number of ethico-legal issues have come to the forefront. Nijboer, Clausen, Allison and Haselager (2011) have listed seventeen such issues starting from obtaining informed consent from people with below-threshold consciousness through how to make responsible group decisions in matters of implanting BCI devices, issues concerning personality, personhood and its possible alterations, human dignity, mental integrity, neural data preservation protocols to mind-reading, mind control and privacy issues. It is high time for scientists, engineers, ethicist and regulators to work together to determine the ethical standards and to exercise sufficient techno-prudence in the future development and employment of BCI instead of giving in to imaginary techno-phobias.

Disease spreading on complex networks: Analysis of the Recent Ebola outbreak
Prof. Parongama Sen
Physics Department, Calcutta University

Abstract:Disease spreading on complex networks: analysis of the recent Ebola outbreak Abstract: Modelling the spread of epidemics on complex networks has led to a number of interesting results in the recent past. Starting with a brief overview, we discuss the characteristic features of the Susceptible-Infected-Removed (SIR) model considered on a network embedded in Euclidean space with random long range interactions, chosen following a certain prescription. The data for the Ebola outbreak that occurred in 2014-2016 in three countries of West Africa are analysed within a common framework using this model.


Bribe and Punishment: An Analysis of Harassment Bribery
Prof. Supratim Sengupta
Physical Science Department
Indian Institute of Science Education and Research, Kolkata

Abstract:Harassment bribes, paid by citizens to corrupt government servants for services the former are legally entitled to, constitute one of the most widespread forms of corruption in many countries. While some countries (like India) make both bribe-giver and bribe-taker equally culpable, others impose a higher penalty on the bribe-taker.Evolutionary game theory provides a powerful tool for analyzing such scenarios of social conflict. After giving a brief introduction to evolutionary game theory, I will examine the consequences of symmetric and asymmetric penalties on the proliferation of corruption using deterministic and stochastic evolutionary game theoretic models of bribery in well-mixed(unstructured) and network-structured populations. I will show how evolution of individualchoices in a social conflict under different conditions and for different population structuresaffect the population dynamics, often in unpredictable ways, leading to profound onsequences for the persistence and proliferation of bribery in society.

"Magnetic Field Effects in Photochemistry"

The fourth programme in the Academic Discussion Series organized by J C Bose Science Heritage Museum in collaboration with Cambridge University Press was held at the AcharyaBhaban on August 14, 2017 (2:30 PM – 4:30 PM). The theme of the meeting was Magnetic Field Effects in Photochemistry. The speakers were Prof. SamitaBasu and Prof. DulalSenapati of the Chemical Sciences Division, Saha Institute of Nuclear Physics. The titles and abstracts of the talks are as follows.


Significance of magnetic field effects in photoinduced electron transfer reactions
Samita Basu
Chemical Sciences Division
Saha Institute of Nuclear Physics

In recent years we have been trying to study photophysical and photochemical aspects of inter- and intra-molecular electron/proton transfer and hydrogen abstraction reactions with small chemically and biologically important molecules and interactions of therapeutically important small molecules with proteins and DNA/RNA bases as well as with carbon nano-dots in homogeneous and heterogeneous confined media using steady-state and time-resolved spectroscopic techniques, magnetic field effects and theoretical modeling. Although steady-state and time-resolved absorption and fluorescence help to identify steady-state products and transient intermediates respectively, the importance of magnetic field effect lies in its ability to identify initial spin state of the photo-excited molecule, one of the deciding factors for ultimate products as well as to assess the intermediate distance between geminate spin-correlated radical ions / radicals produced as transients.


"Low Magnetic-Field-Induced Surface Enhanced Transient Spin-Trajectory Modulation (SE-TSTM): Interplay between Intramolecular and Intermolecular Spin-Rephasing"
Dr. Dulal Senapati
Saha Institute of Nuclear Physics, Kolkata-64

Abstract:The role of single-domain ferromagnetic nanostructure and the associated surface for many fold magnetic-field-induced surface enhanced transient spin-trajectory modulation (SE-TSTM) is a new venture in molecular spin dynamics. Though the inter conversion between spin isomers in the excited state is often forbidden by spin selection rule, hopping between two spin trajectory surface is quite probable due to their intramolecular [governed by spin-orbit (L-S) coupling] or intermolecular [governed by spin-mixing (g) or spin-spin (I-S) coupling] spin-rephasing-induced conical intersection. This lecture will explain the spin-trajectory modulation in great details

"Ethnic Ancestry and Diversity in India"


Linguistic diversity in India
Prof. Shyamsundar Bhattacharya
Philological Secretary, Asiatic Society, Kolkata
"Genetic ancestry and diversity in India"
Prof. Partha Pratim Majumder
Distinguished Professor and Founder Director, National Institute of Biomedical Genomics,Kalyani and Professor, Indian Statistical Institute, Kolkata

Abstract:In India there are numerous spoken languages, considerable number of written languages (some with a long standing written traditions) including hundreds of dialectal forms, one margin into the next. Many of them have never been properly identified. Therefore, languageidentification is not a simple matter.

Of course, Grierson’s Linguistic Survey of India (1896-1928) recorded 179 languages and 544 dialects in India, people of India Series of the Anthropological Survey of India (1993) have identified 325 languages. However, the only source of official data on languages is the Indian decennial Censuses. The last Censuses of 2001 reports 122 languages (of which 22 are included in the 8th Schedule of the Indian Constitution) and 234 identifiable mother tongues grouped under appropriate languages are a linguistic abstraction of 1635 mother tongues reported by the people indicating their perception of linguistic identities.

In addition to their mother tongues, 2001 Census also reports as many as 250 million Indians speak atleast twolanguages and more than 85 million speak three or more languages.

"Integrative Biology: Models and Experiments"


Reprogramming Living Cells With An Engineering Language
Sangram Bagh
Biophysics and Structural Genomics Division
Saha Institute of Nuclear Physics, Kolkata

Abstract: The molecular connectivity between genes and proteins inside a cell shows a good degree of resemblance with complex electrical circuits. This inspires the possibility of engineering a cell similar to an engineering device. Synthetic biology is an emerging field of bioengineering, where scientists use electrical and computer engineering principles to re-program cellular functions with a potential to solve next generation challenges in medicine, energy, and space travel. In this talk, we discuss our synthetic biology efforts to build a technology platform for cellular computation and robotics and systems biology effort to understand the effect of zero gravity on human and bacterial cells during space travel.

Modeling mitosis in mammalian and yeast cells
Dr. Raja Paul
Indian Association for the Cultivation of Science, Kolkata

Abstract: Accurate chromosome segregation during mitosis is critical to maintain genome stability and prevent erroneous cell division. To this aim, assembly of the mitotic spindle using a set of highly dynamic bio-polymers, known as microtubules (MT)must be coordinated with establishment of chromosomal attachment with the spindle via a specific structure on the chromosome called kinetochore (KT). The MTs of a correctly configured (bipolar) mitotic spindle must interact with the chromosomes (KTs) so that the two sister chromatids interact with opposite spindle poles.This configuration will allow the sister chromatids to be pulledto opposite ends of the cell upon chromosomal separation, thusleading to the formation of two daughter cells with the correct chromosomenumber. While mammalian cells divide via open mitosis (nuclear envelop breaks down), chromosome segregation in budding yeast cells occur within the nucleus known as closed mitosis. In closed mitosis, the entire nucleus migrates to a specific location within the cell before segregation. I will discuss the computer modeling of kinetochore microtubule interactionthat correctly predicts experimentally-observed spindle assembly times with minimum error rates in both mammalian and yeast cells. I will further discuss the nuclear migration, spindle positioning in budding yeast. The model can be used to elaborate other features of the mitotic spindle including chromosomal oscillation and various spindle phenotypes.
