ANPA Monthly Talk Series: Dr. Kapil Adhikari

Doing science in Nepal is a daunting task if one takes science as a methodological concept rather than as mere instrumental endeavor. With promulgation of a number of policies that are directly related to the science and technology by Federal and State Government of Nepal, there has been possibilities of expanding science outside the hegemonic center. However too much emphasis on instrumental aspect of science is undermining the culture of research and real innovations. Physics Research Initiatives (PRI) Pokhara promotes science culture in Nepal among the science practitioners. PRI has envisioned to establish a physics research center in Pokhara in the model similar to other successful research centers around the world, such as ”Aspen center for Physics”. The primary goal of the initiative is to engage science students in research and establish a sense of research culture. In addition, it also aims to engage society in general in the science literacy. The secondary aim includes but not limited to , scientific-tourism, science advocacy, science diplomacy etc. The talk will focus on sharing experiences and exploring the possibilities and challenges of doing physics in Nepal, specially outside Kathmandu. The experience of PRI working as a science consultant at various committees in drafting science policies at the provincial level will also be discussed. This talk will also include some of the undergoing projects in PRI for possible collaboration with other research groups around the globe.

ANPA Monthly Talk Series: Prof. Dr. Binil Aryal

Future of Astronomy and Physical Cosmology:
Nobel Prize in Physics 2019

Date & Time:
Monday Nov 4th, 8:00 AM  (Nepal)
Sunday Nov 3rd, 9:00 PM EST, USA)


A big part of the history of the development of cosmology and astronomy has been the art of choosing useful working hypotheses. Astronomy and cosmology have a substantial observational and theoretical basis, but our standard model still depends on some working assumptions. I will try to explain the nature of the issues behind these assumptions, the guidance we might find from past resolutions of such issues, and the models we need to consider for the future of research in this subject. My talk will be mostly dedicated to Peebles's contribution to understand the evolution of the Universe. In addition, I will briefly note the importance and new techniques to explore habitable zone (exoplanets, etc.) in the observable universe.

ANPA members will be sent a Webex link by Email.
This event is a public talk intended for general population. Please become an ANPA member to support us.

ANPA Talk: The Mechanical Bidomain Model of Cardiac Tissue

Dr. Kharanan Sharma
Oakland University, Rochester, MI


Mechanotransduction is the mechanism by which mechanical forces cause the heart to remodel. Researchers understand qualitatively that mechanotransduction can arise from the coupling of the cytoskeleton and extracellular matrix by integrins in the cell membrane. A complete description of mechanotransduction, however, requires this idea be expressed quantitatively using a mathematical model. To be useful, this model must predict where mechanotransduction occurs in the heart. Predicting growth and remodeling in response to mechanotransduction could be useful for understanding cardiac disease, and could be relevant to tissue engineering. The mechanical bidomain model is a multiscale mathematical model that represents cardiac tissue as a continuum yet accounts for forces across the myocardial membrane. The model's central hypothesis is that membrane forces acting on integrins are responsible for mechanotransduction, and that these forces arise from differences between intracellular and extracellular displacements. The model predicts different regions of mechanotransduction and remodeling than does the traditional monodomain model.

ANPA Meeting During APS March Meeting 2019

ANPA Meeting During APS March Meeting 2019

ANPA organized a meeting of Nepali scientists during the APS March meeting 2019 at Boston, MA. ANPA was provided a meeting room from the APS. More than 50 Nepali physicists (Professors, Scientists, Graduate students, Editors, Industrialists) attended the meeting. ANPA-EC members Dr. CR Bhatta and Dr. Santosh KC presented overall activities of the ANPA. Recently organized and upcoming programs were presented and discussed among the participants. A couple of professors, Dr. Gopi Kaphle and Dr. Madhav Ghimire from the Central Department of Physics, TU, Nepal also participated in the meeting. They shared their views about the possible collaboration between ANPA and Nepal Physical Society (NPS) to develop the overall physical science research and education in Nepal. Likewise, other participants also promised their support.

ANPA would like to thank all the attendees for their participation, valuable suggestions, and support.

Thank you.

Potential Efficacy of the Monte Carlo Dose Calculations of 6MV Flattening Filter-Free Photon Beam of M6 Cyberknife® System

Taindra Neupane, Theodora Leventouri, and Charles Shang
Department of Physics (Medical Physics) Forida Atlantic University, Florida, USA

The retrospective MapCheck measurements for 50 patient’s treatment plans suggested that the MapCheck could be effectively employed in routine patient specific quality assurance in M6 Cyberknife with beams delivered at different treatment angles. However, it suggested that for highly intensity modulated MLC plans, small segments of width < 8 mm should further be analyzed with a modified (-4%) correction factor. The preliminary results of the MC simulations of M6 Cyberknife using the EGSnrc program for 2-5 millions of incident particles histories in BEAMnrc and 10-20 millions in DOSXYZnrc have shown dose uncertainties within 3% for all the open fields (7.6 x 7.7 mm2 to 100 x 100 mm2). The energy and FWHM of incident particle source were optimized by comparing with water phantom measurements and the optimized energy, E = 7 MeV and FWHM = 2.2 mm were found. Good agreements for the field size (within 2%) and the dose outputs (within 3%) were found between the MC simulations and measurements in water phantom at 800 mm SAD for all the open fields. This research can further be extended to small MLC segments to investigate the field specific and detector specific correction factors using Gamma analysis and adapting the parallel computing in future.

Graphene as a high-throughput platform to measure the charge dynamics at organic semiconducting interfaces

Bhupal Kattel, Tika R. Kafle, Liang Qin, and Wai-Lun Chan

Department of Physics, University of Kansas, Lawrence, KS 66045, USA


The formation of charge transfer (CT) excitons at the interface of organic semiconductors hinders the charge generation efficiency in devices such as photovoltaics and photodetectors. Therefore, a complete picture of how the tightly-bound CT excitons dissociate into free carriers is essential to improve the performance of these devices. The overall charge extraction mechanism can involve multiple stages such as charge transfer and charge separation. In this talk, I will present our newly developed time-resolved photoelectrical technique to measure the dynamics of charge-separation at a prototype organic donor-acceptor interface: Zinc phthalocyanine/fullerene (ZnPc/C60) interface. This method utilizes graphene as the electrical sensor to measure the ultrafast dissociation dynamics of CT excitons. By controlling the thickness of sample, we selectively measure the dissociation of the delocalized and localized CT states. We observe two distinct channels of dissociation- athermal dissociation of the hot-delocalized CT states and the thermally-activated dissociation of the localized CT states. The former channel is found to have faster dissociation rate and yield ~3 times higher than the latter. I will also shortly present the use of this technique in other materials such as hybrid perovskite-PCBM interfaces, in order to demonstrate the versatility of our method.
