Advanced Healthcare Materials, EarlyView.This study introduces an innovative approach to treating intervertebral disc degeneration using ultrasound‐triggered in situ hydrogel formation. Proof‐of‐concept experiments using optimized biomaterial and ultrasound parameters demonstrate partial restoration of biomechanical function and successful integration into degenerated disc tissue, offering a ...

A five-year dendrometer record in two trees of Pinus strobus [PDF]
, 1947 So far as is known to us there is no published account of a dendrometer record of white pine growth behavior. Brown (2) studied growth behavior and cambial activity using the histological method; Goldthwait and Lyon (5) studied secondary growth in ...

Isoscapes of tree-ring carbon-13 perform like meteorological networks in predicting regional precipitation patterns [PDF]
, 2013 Stable isotopes in tree rings provide climatic information with annual resolution dating back for centuries or even millennia. However, deriving spatially explicit climate models from isotope networks remains challenging.

Neue Ergebnisse zur Gletscher- und Klimageschichte des Spätmittelalters und der Neuzeit [PDF]
Geographica HelveticaThis article contributes to the glacier and climatic fluctuations during the late Middle Ages and the Modern Times. With the aid of radiocarbon dating of fossil woods and a fossil soil (fAh) located in the gletschervorfeld of two glaciers (Glacier de ...

Timing of False Ring Formation in Pinus halepensis and Arbutus unedo in Southern Italy: Outlook from an Analysis of Xylogenesis and Tree-Ring Chronologies [PDF]
, 2016 Mediterranean tree rings are characterized by intra-annual density fluctuations (IADFs) due to partly climate-driven cambial activity. IADFs are used as structural signals to gain information on relations between environmental conditions and eco ...

Advanced Healthcare Materials, EarlyView.This manuscript describes the cultivation of viable microvessels from cryopreserved human brain tissue. When embedded in hydrogels and cultured in microfluidic devices, these microvessels exhibit complex architectures reminiscent of arterioles and capillaries, can be perfused, and display intact barrier function. Collectively, these results demonstrate

The Isomorphism Relation Between Tree-Automatic Structures [PDF]
, 2010 An $\omega$-tree-automatic structure is a relational structure whose domain and relations are accepted by Muller or Rabin tree automata. We investigate in this paper the isomorphism problem for $\omega$-tree-automatic structures.

Using Annual Resolution Pollen Analysis to Synchronize Varve and Tree-Ring Records [PDF]
Quaternary, 2019 Fossil wood and varved lake sediments allow proxy analysis with exceptionally high, (sub-)annual resolution. Both archives provide dating through ring and layer counting, yet with different accuracy. In wood, counting errors are small and can be eliminated through cross-dating because tree-rings show regionally synchronous patterns. In varved sediments,
