Achieving High ON State Current through Ferroelectric Polarization‐Dependent Interfacial Resistance Switching in Undoped Orthorhombic HfO2 Films

Advanced Functional Materials, EarlyView.
Ferroelectric tunnel junction devices based on epitaxial undoped ferroelectric HfO2 films demonstrate stable switching endurance of over 106 switching cycles, low write voltages of ±3 V, 16 measured resistance states, and neuromorphic capability.

Clarifying Influences of Sampling Bias (Concentration) and Locational Errors (Uncertainties) on Precision or Generality of Species Distribution Models

Land
Locational errors and sampling bias may produce unrepresentative species distribution models. To decompose the influence of errors, I modeled species distributions of 31 mammal species from georeferenced records and random samples from range maps, with ...

Maps From Mud—Using the Multiple Scenario Approach to Reconstruct Land Cover Dynamics From Pollen Records: A Case Study of Two Neolithic Landscapes

Frontiers in Ecology and Evolution, 2018
Pollen records contain a wide range of information about past land cover, but translation from the pollen diagram to other formats remains a challenge.

The microfossil record of early land plants [PDF]

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2000
Dispersed microfossils (spores and phytodebris) provide the earliest evidence for land plants. They are first reported from the Llanvirn (Mid–Ordovician). More or less identical assemblages occur from the Llanvirn (Mid–Ordovician) to the late Llandovery (Early Silurian), suggesting a period of relative stasis some 40 Myr in duration.

Start, Stop, Rewind, Repeat—Cyclic Exposure of Adipose Stromal Cells‐derived Cartilage Organoids to Chondrogenic and Proliferative Cues to Achieve Scaled‐up and Customizable Bone Formation by Endochondral Ossification

Advanced Healthcare Materials, EarlyView.
This study exploits the plasticity of ASCs‐derived cartilage organoids which generate a perichondrial layer of MSCs when exposed to cyclic chondrogenic/proliferative cues. Using these organoids as building blocks, we develop (i) Phalange Shaped Tissue Engineered Cartilage (Pa‐TECs), recapitulating endochondral ossification suitable for the treatment of

ROPES Reveals Past Land Cover and PPEs From Single Pollen Records

Frontiers in Earth Science, 2018
Quantitative reconstructions of past vegetation cover commonly require pollen productivity estimates (PPEs). PPEs are calibrated in extensive and rather cumbersome surface-sample studies, and are so far only available for selected regions.

First record of a pterosaur landing trackway [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2009
The terrestrial progression of pterosaurs, the flying reptiles of the Mesozoic Era, has been debated for over two centuries. The recent discovery of quadrupedal pterodactyloid pterosaur tracks from Late Jurassic sediments near Crayssac, France, shows that the hindlimbs moved parasagittally, as in mammals, birds and other dinosaurs, and the ...

Polyimide‐Linked Hexaazatriphenylene‐Based Porous Organic Polymer with Multiple Redox‐Active Sites as a High‐Capacity Organic Cathode for Lithium‐Ion Batteries

Advanced Materials, EarlyView.
A high‐capacity polyimide‐linked porous organic polymer (HAT‐PTO) incorporating numerous redox‐active centers is synthesized via a hydrothermal reaction, delivering a high theoretical capacity of 484 mAh g−1. In situ hybridization with carboxyl‐functionalized multiwalled carbon nanotubes enhances conductivity and stability, achieving 397 mAh g−1 at C ...

The Basel Land Records Ground Truth: An Annotated Dataset for Information Extraction on German-Language Administrative Records

Journal of Open Humanities Data
We present a dataset based on the Historical Land Records of Basel, covering the period 1400–1700. The dataset comprises 829 source excerpts in premodern German containing more than 50,000 tokens and 30,000 annotations.
