Fire–Climate–Vegetation Linkages In A Quaking Aspen Forest During The Late Holocene, R. Justin Derose, Jesse L. Morris

Wildland Resources Faculty Publications

Fire plays an important role in shaping forested ecosystems around the globe. Unlike many other fire-driven forest types, our understanding of pre-settlement fire behavior in quaking aspen (Populus tremuloides) systems is limited. To better understand the frequency and severity of fires in a putatively stable quaking aspen forest, a small, key watershed was selected for sediment coring to reconstruct fire history, vegetation change, and climatic variability. The study aim was to explore the fire–climate–vegetation linkages in an aspen-dominated catchment. For the past ~4000 years this basin has been dominated by quaking aspen but also subalpine fir (Abies …

(R2133) Analysis Of A Bulk Queue With Balking, Adaptive Overloading Service, Multiple Vacation, Inspection And Rework, S. Karpagam, R. Lokesh

Applications and Applied Mathematics: An International Journal (AAM)

We consider a queueing system that utilizes a single server to manage product flow through bulk and overload service modes, depending on queue length. Balking occurs when the queue length reaches ‘N’. After completion of service, products undergo quality inspection, with defective products sent for rework based on specific probabilities. If the product is non-defective, the server continues processing until the queue length exceeds a certain threshold; beyond this point, the server is either routed back to bulk service or directed to an overload service. Also, the server goes into a vacation mode when the queue size is below a …

Rethinking Pakistan Studies: The Grounds Of Regional Knowledge After South Asia, Zoya Sameen

FAS Pakistan

This article rethinks Pakistan Studies as both a pedagogical project and a field of knowledge by examining the limits of history as a tool of legitimation. It argues that in the public sphere, history often serves to authorize the present, and shows how Pakistan Studies has historically operated within this framework. At the same time, the article suggests that this condition opens up another possibility: to understand history not as passive inheritance but as an active demand upon the present. Seen in this light, Pakistan Studies emerges not as a stable body of knowledge but as a series of shifting …
