Hamilton-Jacobi theory of discrete, regular constrained systems
Güler, Y. (Springer Science and Business Media LLC, 1987-8)
The Hamilton-Jacobi differential equation of a discrete system with constraint equationsG α=0 is constructed making use of Carathéodory’s equivalent Lagrangian method. Introduction of Lagrange’s multipliersλ˙α as generalized velocities enables us to treat the constraint functionsG α as the generalized momenta conjugate toλ˙α. Canonical equations of motion are determined.
Novel insights on demographic history of tribal and caste groups from West Maharashtra (India) using genome-wide data

The South Asian subcontinent is characterized by a complex history of human migrations and population interactions. In this study, we used genome-wide data to provide novel insights on the demographic history and population relationships of six Indo-European populations from the Indian State of West Maharashtra. The samples correspond to two castes (Deshastha Brahmins and Kunbi Marathas) and four tribal groups (Kokana, Warli, Bhil and Pawara). We show that tribal groups have had much smaller effective popul...
Self-reporting and self-regulating liquid crystals
Kim, Young-Ki; Wang, Xiaoguang; Mondkar, Pranati; Büküşoğlu, Emre; Abbott, Nicholas L. (Springer Science and Business Media LLC, 2018-05-24)
Liquid crystals (LCs) are anisotropic fluids that combine the long-range order of crystals with the mobility of liquids(1,2). This combination of properties has been widely used to create reconfigurable materials that optically report information about their environment, such as changes in electric fields (smart-phone displays)(3), temperature (thermometers)(4) or mechanical shear(5), and the arrival of chemical and biological stimuli (sensors)(6,7). An unmet need exists, however, for responsive materials t...
Atmospheric iridium at the South Pole as a measure of the meteoritic component
Tuncel, Süleyman Gürdal (Springer Science and Business Media LLC, 1987-10)
The measurement of iridium (Ir) in atmospheric samples is important because it gives information on the short-term flux of extraterrestrial material without interference from fragmentation products from large bodies. Such information cannot be obtained from sediment samples, because sediment samples integrate over millions of years and include contributions of large bodies impacted in that time period. In addition to flux information, through the analysis of Ir in atmospheric samples we can also evaluate a ...
Mechanical Fracturing of Core-Shell Undercooled Metal Particles for Heat-Free Soldering
Çınar, Simge; Chen, Jiahao; Thuo, Martin (Springer Science and Business Media LLC, 2016-02-23)
Phase-change materials, such as meta-stable undercooled (supercooled) liquids, have been widely recognized as a suitable route for complex fabrication and engineering. Despite comprehensive studies on the undercooling phenomenon, little progress has been made in the use of undercooled metals, primarily due to low yields and poor stability. This paper reports the use of an extension of droplet emulsion technique (SLICE) to produce undercooled core-shell particles of structure; metal/oxide shell-acetate ('/'=...
