In a well forgotten memoir of 1890, Andrei Markov devised a convergence acceleration technique based on a series transformation which is very similar to what is now known as the WilfZeilberger (WZ) method. We review Markov’s work, put it in the context of modern computeraided WZ machinery, and speculate about possible reasons of the memoir being shelved for so long.

In the 1990's, the WZ method has been the method of choice in resolving new conjectures for hypergeometric identities. The object here is to compare the WZ method with Pfaff's method. Such a comparison should (it is hoped) provide some suggestions for the further development of each method.

In this Dissertation I present a detailed study of pp̄ → WZ production using fully leptonic decays of W and Z bosons with electrons and muons in the final state. Data used for the study were collected by the DØ detector at the Fermilab pp̄ collider with a centerof-mass energy of √ s = 1.96 TeV and correspond to 4.1 fb−1 of integrated luminosity. The most precise measurement of the WZ production c...

BACKGROUND Previous epidemiological studies have investigated the association between allergic symptoms and cancer occurrence. However, the role of allergy in cancer has been elusive, especially for the female population. METHODS We examined the relationship between cancer prevalence and common allergic symptoms of rhinoconjunctivitis (RC) and wheezing (WZ) among NHANES III female participant...

An interesting integral originally obtained by Tefera (“A multiple integral evaluation inspired by the multi-WZ method,” Electron. J. Combin., 1999, #N2) via the WZ method is proved using calculus and basic probability. General recursions for a class of such integrals are derived and associated combinatorial identities are mentioned. 1 Background The integral in question reads

Introduction Suppose that  is a commutative ring with identity,  is a unitary -module and  is a multiplicatively closed subset of .  Factorization theory in commutative rings, which has a long history, still gets the attention of many researchers. Although at first, the focus of this theory was factorization properties of elements in integral domains, in the late nineties the theory was gener...

Abstract As a mitigation target for Indonesia’s Forestry and Other Land Use (FOLU) Net Sink 2030, Gunung Halimun Salak National Park (GHSNP) has high potential. However, there is lack of data on tree species composition vegetation cover, particularly in the traditional zone (TZ). This study aims to estimate cover GHSNP 2016, 2019, 2022, as well TZ compared wilderness (WZ). used Sentinel-2 image...
