Rapid technical advances in the field of computeropened new avenues in animal behavior *** （CA） and virtual reality （VR） haveAnimated stimuli are powerful tools as theyoffer standardization, repeatability, and complete control over the stimulus presented, thereby＂reducing＂ and ＂replacing＂ the animals used, and ＂refining＂ the experimental design in line withthe 3Rs. However, appropriate use of these technologies raises conceptual and technical *** this review, we offer guidelines for common technical and conceptual considerations related tothe use of animated stimuli in animal behavior research. Following the steps required to create ananimated stimulus, we discuss （I） the creation, （11） the presentation, and （111） the validation of CAsand VRs. Although our review is geared toward computer-graphically designed stimuli, consider-ations on presentation and validation also apply to video playbacks. CA and VR allow both new be-havioral questions to be addressed and existing questions to be addressed in new ways, thus weexpect a rich future for these methods in both ultimate and proximate studies of animal behavior.

Himalayan Tectonics:Preface

引用

Geoscience Frontiers 2019年第3期10卷 791-792页

作者： Kyle Larson Christopher j. spencer Tectonics and Geodynamics Earth Environmental and Geographical Sciences IKBSAS University of British Columbia Earth Dynamics Research Group The Institute for Geoscience Research (TIGeR) Department of Applied Geology Curtin University

The Himalayan-Tibetan orogen system serves as the modern paradigm for understanding convergence-related processes in orogenic belts. The advancements made studying the region have been applied to other ancient orogenic belts leading not only to a better understanding of their development, but also of secular changes in collisional processes. As more advanced methodologies are introduced and utilized in geological research, the type, scale, and quality of data available enable quantification of geological processes not previously possible. These complex and robust datasets now form the core of many of the research proj.cts undertaken across the Himalaya and continue to provide unprecedented insight into the myriad different aspects of the evolution of the collisional system.

Transforming bilayer MoS2 into single-layer with strong photoluminescence using UV-ozone oxidation

引用

Nano Research 2015年第12期8卷 3878-3886页

作者： Weitao Su Naresh Komar Steve j. spencer Ning Dai Debdulal Roy Institute of Materials Physics Hangzhou Dianzi University Hangzhou 310018 China Ningbo Institute of Materials Technology & Engineering Chinese Academy of Sciences Ningbo 315201 China National Physical Laboratory Hampton Road Teddington Middlesex TWI 10LW UK

The use of single-layer MoS2 in light emitting devices requires innovative methods to enhance its low photoluminescence （PL） quantum yield. In this work, we report that single-layer MoS2 with a strong PL can be prepared by oxidizing bilayer MoS2 using W-ozone oxidation. We show that as compared to mechanically-exfoliated single-layer MoS2, the PL intensity of the single-layer MoS2 prepared by W-ozone oxidation is enhanced by 20-30 times. We demonstrate that the PL intensity of both neutral excitons and trions （charged excitons） can be greatly enhanced in the oxidized MoS2 samples. These results provide novel insights into the PL enhancement of single-layer MoS2.

"Miles wide and miles deep"-Exploring the depth and breadth of geoscience during the first ten years of Geoscience Frontiers

引用

Geoscience Frontiers 2019年第3期10卷 1219-1221页

作者： Christopher j. spencer Nick M.W.Roberts Damian Nance The Institute of Geoscience Research (TIGeR) School of Earth and Planetary Sciences Curtin University NERC Isotope Geosciences Laboratory British Geological Survey Department of Geological Sciences Ohio University Department of Geology and Geophysics Yale University

When early explorers first crossed the Platte River in what is now Nebraska (USA), it was said the river was “a mile wide and an inch deep”(Mokler, 1923;Smith, 1971). This phrase was used to describe not only the difficulty in crossing the river but also in navigating its length. The trouble with a river being too wide is the risk that it won’t provide the depth necessary to be useful. The same thing can be said of multidisciplinary scientific j.urnals. While a j.urnal can claim to be multidisciplinary, there is a risk of it being so broad that its articles can only engage the reader at a superficial level. Nothing could be further from the truth with Geoscience Frontiers. Over the past ten years, this j.urnal has successfully navigated the wide breadth of geoscience while providing a level of depth and detail that rivals discipline-specific j.urnals.

Strategies towards statistically robust interpretations of in situ U-Pb zircon geochronology

Zircon U-Pb geochronology has become a keystone tool across Earth science, arguably providing the gold standard in resolving deep geological time. The development of rapid in situ analysis of zircon （via laser ablation and secondary ionization mass spectrometry） has allowed for large amounts of data to be generated in a relatively short amount of time and such large volume datasets offer the ability to address a range of geological questions that would otherwise remain intractable （e.g. detrital zircons as a sedi- ment fingerprinting method）. The ease of acquisition, while bringing benefit to the Earth science com- munity, has also led to diverse interpretations of geochronological data. In this work we seek to refocus U -Pb zircon geochronology toward best practice by providing a robust statistically coherent workflow. We discuss a range of data filtering approaches and their inherent limitations （e.g. discordance and the reduced chi-squared; MSWD）. We evaluate appropriate mechanisms to calculate the most geologically appropriate age from both 238U/206pb and 207pb/206pb ratios and demonstrate the cross over position when chronometric power swaps between these ratios. As our in situ analytical techniques become progressively more precise, appropriate statistical handing of U-Pb datasets will become increasingly pertinent.

Secular change in earth processes： Preface

*** Uniformitarianism is a traditional approach used in many areas of geoscience that assumes the geologic processes observed today operated similarly throughout all of Earth history（Hutton,1788;Windley,1993）,with such an ideology commonly encapsulated by the maxim＂the present is the key to the past＂.This concept is closely associated with the philosophical principle of Occam’s razor.
