Subhash R. Walimbe is Professor and former Chair of the Anthropology Department of Pune University. He received his Master’s (1972) and Ph.D. (1078) degree from the Pune University. His long association with Deccan College Post-Graduate and Research Institute (Deemed University) helped him establish fully equipped laboratory solely devoted for archaeological human skeletal research. This being the only facility in the subject in India, over the last 35 years, Walimbe and his team had an opportunity to examine human remains from over 65 archaeological sites (dated between 8000 BCE to 800 AD) collected by various Indian Universities. He is also instrumental in creating national level facility of ancient-DNA laboratory in India. He is executive member of several professional bodies and recipient of research finding from reputed national and international agencies. Major emphasis of his career research is on examining the relative quality of hunter-gatherer’s and farmer’s health and nutrition. His current research uses ethnographic data to model cultural frontiers of health for archaeological populations. He is the author of edited one book (Wiley-Blackwell), seven monographs / skeletal reports and over 60 articles in peer-reviewed journals. Address: 28, Ideal Colony, Matoshri Sulabha Society, Paud Road, Kothrud, Pune 411029 India

When Professor Barun Mukhopadhyay, the then General Secretary of the Society, called sometime in the last year conferring the honour, I was very much confused. Whether little I could contribute to the anthropological knowledge base deserves this respect? I was not fortunate to be in the academic domain during the Dharani Sen's era. But we grew up with the platform they created for us. I remember, 50 years back, on the 8 th of August 1970 to be precise, in my very first lecture as a postgraduate student, my teacher Professor R.K. Mutatkar taught us about the four sub-branches of anthropology, viz. cultural, physical, archaeological and linguistic. Like several of us, I wanted to find a human fossil ancestor and Siwalik Hills was the first choice! When I talked about my desire while thinking of Ph.D. registration in 1972, I was simply asked to go either to Chandigarh or Kolkata. Not many anthropologists were then working in the area of archaeological anthropology. Chandigarh was not possible for some reasons.

It was propounded that the Aryans, living somewhere outside India, invaded the Indian sub-continent around 1500 B.C. and after supplanting the indigenous powers and cultures settled in India. The Aryans were held responsible for the destruction of the earlier populations (esp. Indus valley civilization) and building of new cultures in the areas they invaded. The subject of this paper is to examine the physical anthropological dimensions of the "Aryan problem", which are two fold: a. "foreign phenotypic element" in the later phases of Harappan culture, and b. the "massacre evidence" at Mohenjo-Daro. Findings of the restudies of Harappan skeletal series and implications thereof for evaluating the 'Aryan Invasion Theory' have been discussed. The findings strongly indicates that the hypothesis of identification of "foreign phenotypic element" or unceremonious slaughter of native Harappans is not supplemented by bone evidence.

In IGRNN model, two state control units are introduced to ensure the linear transmission of hidden state and solve the problem of vanishing gradients of RNN model. In contrast with conventional RNN model, IGRNN can better describe the long-term memory effect of power amplifier, more in line with the physical distortion characteristics of power amplifier. Furthermore the instantaneous gates are used to express the input information implicitly to reduce the redundancy of the input information, and a simpler IGIRNN model is proposed. The complexity analysis indicates that the proposed models have significantly lower complexity than other RNN-based variant structures. A wideband Doherty RF PA excited by 100MHz and 120MHz OFDM signals was employed to evaluate the performance. Extensive experimental results reveal that the proposed IGRNN and IGIRNN models can achieve better linearization performance compared with RNN model and traditional GMP model, and have comparable performance with lower computational complexity compared with the state-of-the-art RNN-based variant models, such as gated recurrent unit (GRU) model. INDEX TERMS Nonlinear RF PA, digital predistortion, recurrent neural network, instant gated, behavioral modeling.

Additional complications arise from the hierarchal and endogamous structure of Hindu social and ritual organization, including the plight of people who occupy the lowest stratum of the hierarchy — ‘untouchables’ (Charsley 1996; Delikge 1992; 1993). Because the system of socioreligious stratification known as caste does not encourage social mobility, new ethnic identity is often sought by groups whose position in the hierarchy is low (Dumont 1980; Klass 1980; Kolinda 1978). Biological anthropologists are interested in the caste system for the opportunities it offers to understand the interaction of cultural behaviour with the biological patterning of human genetic and phenotypic diversity (Majumder 1998; Majumderet al. 1990; Malhotra 1974). Although most Western...

Various attempts have been made to describe and explain its morphological, genetic, cultural and linguistic diversity. Some claim an indigenous origin for regional populations while other scholars attribute a considerable fraction of this variability to the large-scale immigrations into India in different time periods.
