Mukul Kundu Papers
No full textMukul Kundu (1930-2010) was a professor emeritus at the University of Maryland, College Park in the Astronomy and Physics. He received his Doctorate of Science from the University of Paris (Sorbonne) in 1957. Before coming to the University of Maryland he was an associate professor at Cornell University and a Professor at the Tata University of Fundamental Research in India. He was a U.S.Senior Scientist awardee of the Humboldt Foundation (Humboldt Prize). This collection consists of Astronomy Department committee files, correspondence, research papers, photographs, book reviews, and lecture materials. His papers contain numerous images of sun spots and solar flares. Dr. Kundu's research focused on solar and stellar radio physics, galactic supernova remnants, microflares, and solar active regions. This collection is unprocessed but a preliminary inventory is available
Joint versus Individual Liability in Microfinance – A Comparative Impact Evaluation Through Natural Experiment
No full textIn this paper we want to do a comparative impact evaluation among the participants of two separate types of microfinance system; a microfinance system operated through individual liability microcredit contract represented by VSSU and a microfinance system under SGSY scheme of the Government of India which is operated through joint liability microcredit contract through forming Self-Help Group among the rural people mainly married women. This impact evaluation is done through Natural experiment whose time span is two years. It was observed that in the base line period the participants of VSSU are comparatively in better economic position than the participants of SGSY scheme and non participants who are treated as control group in our experiment. It is established that increment of monthly income among the member households of VSSU is more than the member households under SGSY scheme but when we consider the outcome variable as increment of monthly per capita consumption expenditure we see the reverse picture. There is no significant difference on expenditure for human development purposes is observed among the participants of two different types of microfinance system and even at the end line period both the member households still consider expenditure for health and education is luxury. When we consider intra household decision making power through constructing Women’s Empowerment Index as an outcome variable then the change is maximum among the female SHG members under SGSY scheme. We have also estimated the optimum size of micro credit which is helpful for all types of rural participants to improve their economic conditions within a short span of time.Individual Liability, Joint Liability, Income, Consumption Expenditure, Human Capital Expenses, Women’s Empowerment

Shifted nonlocal Kundu type equations: Soliton solutions
No full text© 2022 The Author(s)We study the shifted nonlocal reductions of the integrable coupled Kundu type system. We then consider particular cases of this system; namely Chen–Lee–Liu, Gerdjikov–Ivanov, and Kaup–Newell systems. We obtain one- and two-soliton solutions of these systems and their shifted nonlocal reductions by the Hirota bilinear method. We present particular examples for one- and two-soliton solutions of the reduced shifted nonlocal Chen–Lee–Liu, Gerdjikov–Ivanov, and Kaup–Newell equations
Evoked intracranial potentials in patients with epilepsy
No full textThe parameters affecting the evoked response in the brain as a result of brain stimulation is not well understood. Yet it is widely used in research and clinical settings (e.g. responsive neurostimulation to treat intractable multifocal epilepsy in humans). In an effort to better understand the parameters that affect the response to brain stimulation, single pulse electrical stimulation was delivered to different brain regions of patients with epilepsy undergoing long term monitoring. These data were recorded off depth and surface cortical electrodes. These are the summarized trial data derived from patients. 11 patients are included in this data set. The data are organized into a MATLAB variable type table and saved in .mat form. These data were recorded, epoched, filtered, and processed as described in the submitted manuscript "A systematic exploration of parameters affecting evoked intracranial potentials in patients with epilepsy" by authors Bornali Kundu, Tyler S. Davis, Brian Philip, Elliot H. Smith, Amir Arain, Angela Peters, Blake Newman, Christopher R. Butson and John D. Rolston.
The columns of the table consistent of the following variables:
(1) patientnum - the patient ID number
(2) stimlevel - the stimulation level delivered, in microvolts
(3) stimchan - the number ID of the stimulation channel
(4) respchan - the number ID of the response channel from which the evoked response was measured
(5) isdpth - 1 = the channel was from a depth electrode, 0 = the channel was from a cortical surface electrode
(6) distance - distance between the stimulation channel and response channel in Euclidian space, in mm
(7) issozstim - 1= the stimulation channel was located in the clinical SOZ, boolean variable
(8) issozrep - 1= the response channel was located in the clinical SOZ, boolean variable
(9) posthgpwr100 - raw trial power after bandpass filtering the epoched data from 70-150Hz, calculating the Hilbert transform of the data, and then calculating the mean from 5 - 100ms as described in the methods section, data are log transformed
(10) postrawmav100 - raw voltage data mean from 5-100 ms for the trial, in milivolts, data are log transformed
(11) trials - trial number ID
(12) regionstim - the region of the stimulation channel determined from an atlas as described in the methods
(13) regionresp - the region of the response channel determined from an atlas as described in the methods
(14) issoz - boolean variable, true corresponds to if the stimulation channel, response channel, or both were in the clinical SOZ
(15) regionresptype - categorical description of the region of the response channel
(16) regionstimtype - categorical description of the region of the stimulation channel

Rogue Waves of the Kundu-DNLS Equation
No full textIn this paper, we give the Lax pair and construct the Darboux transformation of the Kundu-DNLS equation. Further-more, the rogue wave solutions of the Kundu-DNLS equation are derived by using the Taylor expansion of the breather solution. What's more, the triangular and the circular patterns of the third rouge solution are displayed

No full textIn this paper, the soliton behavior of the (2+1)-dimensional perturbed Radhakrishnan-Kundu-Lakshmananequation utilizing by the new Kudryashov method is investigated. First of all, the nonlinear ordinary differentialequation form of the perturbed Radhakrishnan-Kundu-Lakshmanan equation has been obtained by inserting thecomplex wave transformation into nonlinear partial differential equation form of the perturbed Radhakrishnan-Kundu-Lakshmanan equation. The algorithm of the proposed method has been expressed and applied to the ob-tained nonlinear ordinary differential equation. Then, a polynomial expression has been achieved and converted tolinear algebraic system. After solving and selecting the appropriate solution set, different soliton solutions of theinvestigated perturbed Radhakrishnan-Kundu-Lakshmanan equation has been derived. Finally, 3D and 2D graph-ics of some solutions are depicted for chosen suitable parameters.</p
