Recent geophysical survey of English monastic sites

Geophysical survey can provide additional detail even from well understood monastic sites. Extended landscape survey in rural settings can reveal wider semi-industrial monastic activity. Vehicle towed ground penetrating radar used to complement earth resistance and magnetic survey

Fore! GPR survey of the Belhus Tudor water gardens

Covid-19 restrictions allowed unique access to this site on a temporarily closed golf course. Vehicle towed ground penetrating radar survey provided rapid coverage of the site. Geophysical survey helped support local volunteer research groups. Significant remains survive despite demolition of the Tudor mansion and landscaping for the golf-course. Detailed topographic data was generated from UAV based photography through Structure from Motion

Stepped frequency GPR survey with a multi-element array antenna: Results from field application on archaeological sites

The value of large scale GPR surveys to landscape archaeology is becoming increasingly important (e.g. Nishimura and Goodman, 2000; Neubauer et al., 2002; Leckebusch, 2003; Linford, 2004). However, the use of conventional single channel instrumentation requires either a significant investment of time for data acquisition or a compromise between sampling methodology and the area of coverage. The recent development of multi-channel, vehicle towed GPR arrays offers the potential to obtain very d..

FAK Promotes Osteoblast Progenitor Cell Proliferation and Differentiation by Enhancing Wnt Signaling

Decreased bone formation is often associated with increased bone marrow adiposity. The molecular mechanisms that are accountable for the negative correlation between bone mass and bone marrow adiposity are incompletely understood. Focal adhesion kinase (FAK) has critical functions in proliferation and differentiation of many cell types; however, its roles in osteoblast lineage cells are largely unknown. We show herein that mice lacking FAK in Osterixâ expressing cells exhibited decreased osteoblast number and low bone mass as well as increased bone marrow adiposity. The decreased bone mass in FAKâ deficient mice was accounted for by decreased proliferation, compromised osteogenic differentiation, and increased adipogenic differentiation of bone marrow Osterixâ expressing cells resulting from downregulation of Wnt/βâ catenin signaling due to the reduced expression of canonical Wnt ligands. In contrast, FAK loss in calvarial preosteoblasts had no adverse effect on their proliferation and osteogenic differentiation and these cells had intact Wnt/βâ catenin signaling. © 2016 American Society for Bone and Mineral Research.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/135488/1/jbmr2908_am.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/135488/2/jbmr2908-sup-0001-SuppData-S1.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/135488/3/jbmr2908.pd

CPT1a-dependent long-chain fatty acid oxidation is essential for maintaining glucagon secretion from pancreatic islets

Glucagon, the principal hyperglycemic hormone, is secreted from pancreatic islet α cells as part of the counter-regulatory response to hypoglycemia. Hence, secretory output from α cells is under high demand in conditions of low glucose supply. Many tissues oxidize fat as an alternate energy substrate. Here, we show that glucagon secretion in low glucose conditions is maintained by fatty acid metabolism in both mouse and human islets, and that inhibiting this metabolic pathway profoundly decreases glucagon output by depolarizing α cell membrane potential and decreasing action potential amplitude. We demonstrate, by using experimental and computational approaches, that this is not mediated by the KATP channel, but instead due to reduced operation of the Na+-K+ pump. These data suggest that counter-regulatory secretion of glucagon is driven by fatty acid metabolism, and that the Na+-K+ pump is an important ATP-dependent regulator of α cell function

VLA/Realfast Detection of a Burst from FRB 180916.J0158+65 and Tests for Periodic Activity

We report on the detection of a burst from FRB 180916 by realfast/Very Large Array and present software for interpreting fast radio bursts (FRB) periodicity. We demonstrate a range of periodicity analyses with bursts from FRB 180916, FRB 121102 and FRB 180814. Our results for FRB 180916 and FRB 121102 are consistent with published results. For FRB 180814, we did not detect any significant periodic episodes. The realfast-detected and other high-frequency bursts for FRB 180916 tend to lie at the beginning of the activity window, indicating a possible phase-frequency relation. The python package frbpa can be used to reproduce and expand on this analysis to test models for repeating FRBs
