On Topological Chaos in the Robinson-Solow-Srinivasan Model
No full textIn this paper, we offer an instance of (topologically) chaotic optimal behavior in a twosector model with irreversible investment, originally formulated by Robinson, Solow and Srinivasan. Our result follows from the theory of turbulence in non-linear dynamical systems, and relies only on the existence of a continuous optimal policy function. The fact that there is a unique optimal program from each initial stock when future utilities are discounted by a factor smaller than the labor-capital ratio may be of independent interest.

SWAT Literature Database
No full textWelcome to the SWAT Literature Database for Peer-Reviewed Journal Articles. The database is an outgrowth of the “SWAT review article” that was published in Trans. ASABE in 2007
(Gassman et al., 2007), that can be accessed at https://swat.tamu.edu/publications/
(Comprehensive review of SWAT model article). Gassman et al (2014) provided description of the types of studies included, database structure, search options and other details for the database at that time (1,700 articles were indexed at that point
Dr. Raghavan Srinivasan (https://blackland.tamu.edu/people/srinivasan-raghavan/) provided
the initial inspiration for the database. Mr. Curtis Balmer, Center for Agricultural and Rural Development (CARD), Iowa State University (ISU), created and maintained the on-line database
from 2009 through the middle of 2022 (until his untimely death). Administration of the database was transferred to Texas A&M AgriLife on October 1, 2024 and is now accessible at

Dr M. R. Srinivasan: A Gentle Visionary
No full textDr. M. R. Srinivasan (1930–2025) was a pioneering Indian nuclear engineer and is hailed as the father of India’s civil nuclear programme. He played a key role in developing indigenous nuclear power reactors and establishing institutions like the Nuclear Power Corporation of India Ltd (NPCIL). As former Chairman of the Atomic Energy Commission, his leadership ensured India’s self-reliance in nuclear technology despite global restrictions. For his contributions, he was honoured with the Padma Shri, Padma Bhushan, and Padma Vibhushan

The data and code are organized in the following folders:
1. Raw Data: This folder contains the sample data, electoral/administrative data, journalist survey data, and the voter survey data.
2. master.do runs all the do-file in Sub-DoFiles which create the datasets necessary for analysis from the raw datasets
3. Analysis Data: Holds all the intermediate files created by master.do
4. Every other folder contains the do-file or .m file to create the table corresponding to its name
Bronze image casting in Tanjavur District, Tamil Nadu: Ethnoarchaeological and archaeometallurgical insights
No full textThe profusion of metal images made in the Tanjavur region, going back to the early medieval Chola
bronzes of the 9th-13th century ranks amongst the finest of Indian artistic expressions. Clusters of artistic and
artisanal activities have thrived over generations in the Tanjavur district including metalworking workshops for
bronze and bell metal casting of images and ritual objects especially around Swamimalai and Kumbakonam.
Ethnometallurgical and archaeometallurgical insights on the making of icons at Swamimalai are highlighted from
observations made over the past couple of decades, especially in relation to making comparisons with historical
practices of bronze casting going back to Chola times. Since the processes are rapidly undergoing change, to get
a better sense of the trajectory of past practices, this paper particularly aims to highlight unpublished observations
made by the author going back to her first visits in 1990-1, as background to her doctoral work (Srinivasan 1996)
and in relation to observations reported by other scholars going back to the early landmark efforts of Reeves (1962).
These observations were particularly made by the author at the workshop of late master craftsman Devasena
Sthapathy, in his time the most renowned of Swamimalai Sthapathis. His son Radhakrishna Sthapathy has now
inherited this mantle. While Levy et al (2008) give a more recent account of image casting at the workshop of
Radhakrishna Sthapathy, this paper attempts to also contextualise the previous trajectory that has not been covered
much therein. Since their workshop now goes under the name of Sri Jayam Industries, for the sake of convenience
it will be referred here by the same name
Notch Signaling: Mechanistic And Functional Studies In Intestinal Stem Cells And Colorectal Cancer Cells
No full text: The study of stem cell regulation in intestinal and colonic tissues is an area of significant focus within the scientific community, providing mechanistic insight into biological process and offering translational clinical potential. In this thesis we address the contribution of NOTCH signaling in maintaining the stem cell niche by modulating the mode of stem cell division and receptor-ligand interactions for cell-cell communication. Furthermore, we examine NOTCHmediated spatiotemporal recovery of the intestinal stem cell (ISC) niche following single cell ablation. Finally, we demonstrate that elevated NOTCH signaling exists under conditions of physiological stress and in colon cancer initiating cells (CCICs), promoting tumorigenic potential of the intestinal epithelium. Overall, our research highlights the underlying complexities of NOTCH signaling as an essential pathway to maintain intestinal homeostasis and may inspire development of novel CRC therapeutic strategies.
