Veterans Residing in Adams County, Pennsylvania, 1840-1930

open access: yes, 2004
The federal decennial census provides a wide-ranging set of data for analysis. The census forms for each ten-year cycle from 1790 until 1930 have been released to the public for access. The tabulations of 1840, 1910, and 1930 contain data relating to the

Fixed Point Theorems in Cone Banach Spaces

open access: yesFixed Point Theory and Applications, 2009
In this manuscript, a class of self-mappings on cone Banach spaces which have at least one fixed point is considered. More precisely, for a closed and convex subset of a cone Banach space with the norm , if there exist , , and satisfies the ...

Map and Archival Evidence of the Historical Avulsion of the Brahmaputra River

open access: yesThe Geographical Journal, Volume 192, Issue 2, June 2026.
Short Abstract One of the world's great rivers, the Brahmaputra, avulsed—changed course—significantly sometime between the dates of 1765 and 1830. These are the dates of surveys by James Rennell (grey) and Richard Wilcox (black), both under the direction of the East India Company; no other surveys between these dates can refine the estimate of the ...

Crustal Responses to the Destruction of Continental Lithosphere: Insights From Radial Anisotropy of the Tanlu Fault Zone, Eastern China

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Since the Mesozoic, much of the eastern China lithosphere was removed through thermo‐mechanical erosion and delamination, yet the effects on the overlying crust remain unclear. The Tanlu Fault Zone (TLFZ), the region's largest lithosphere‐scale weakness, offers a natural laboratory to assess crustal responses to lithospheric destruction.

An Extension of Gregus Fixed Point Theorem

open access: yesFixed Point Theory and Applications, 2007
Let be a closed convex subset of a complete metrizable topological vector space and a mapping that satisfies for all , where , , , , , and . Then has a unique fixed point. The above theorem, which is a generalization and an extension of the results

Ceramic Particle‐Reinforced Medium‐Entropy Alloys With Outstanding Mechanical Properties Prepared by Novel Micro‐LPBF

open access: yesAdvanced Functional Materials, Volume 36, Issue 37, 7 May 2026.
An innovative medium entropy alloy (MEA) composite material was fabricated via micro laser powder bed fusion (μ‐LPBF) with appropriate nano‐ceramic particles doping and exhibited markedly improved overall performance, including synergistically enhanced strength and ductility, increased hardness and compressive strength, improved wear resistance and ...

On Making Descendant Communities: Three Case Studies From Historical Bioarchaeology

open access: yesAmerican Journal of Biological Anthropology, Volume 190, Issue 1, May 2026.
ABSTRACT Bioarchaeologists, museums and universities, journal editorial boards, and academic professional organizations are working toward ethical engagements with human remains, with a focus on descendant community engagement. This article reexamines past and present bioarchaeological descendant community engagement to consider how “descendant ...

Iterative Approximation to Convex Feasibility Problems in Banach Space

open access: yesFixed Point Theory and Applications, 2007
The convex feasibility problem (CFP) of finding a point in the nonempty intersection is considered, where is an integer and each is assumed to be the fixed point set of a nonexpansive mapping , where is a reflexive Banach space with a weakly ...
