Abstract Unlike in the bulk, at the nanoscale shape dictates properties.The imperative to understand and predict nanocrystal shape led to the development, over several decades, of a large number of mathematical models and, later, their software implementations.In this review, the various mathematical approaches used to model crystal shapes are firs
This paper presents a 10-bit, 600 MS/s direct-sampling sub-Nyquist rate DAC-based frequency-agile wideband transmitter for IEEE 802.22 cognitive radio applications in the VHF/UHF TV band (54 – 862 MHz).Multi-mode reconstruction using Gilbert cells, including non-return-to-zero, return-to-complement, and return-to-complement with reset, allow
Among different endangered animal species, snakes are the most neglected creature looked at with apathy and therefore, are ruthlessly killed, illegally trafficked, and poached for their venom, lucrative skin, meat, and bones for manufacturing of medicines, accessories, and food items.Establishing the identity of the endangered snake species is impo
Regional budgets of pollutants in the atmospheric boundary layer (ABL) provide valuable information on transport and chemical processes, especially over complex terrain where local assessments are not representative.Horizontal transport, vertical transport (advective and non-advective), deposition, emissions and chemical production/destruction cons
