The Archaeology of Animals

Ever since the discovery of fossil remains of extinct animals associated with flint implements, bones and other animal remains have been providing invaluable information to the archaeologist. In the last 20 years many archaeologists and zoo...

27 yr of Spaceborne IR Astronomy: An ISO, Spitzer, WISE, and NEOWISE Survey for Large-amplitude Variability in Young Stellar Objects

Infrared observations can probe photometric variability across the full evolutionary range of young stellar objects (YSOs), from deeply embedded protostars to pre-main-sequence stars with dusty disks. We present 3–8 μ m light curves extendi...

Controlled Plasmonic Coupling in Silver Nanoplate Dimers for Enhanced Plasmonic Sensing

Noble metal nanostructures provide versatile platforms for light manipulation through localized surface plasmon resonances (LSPRs). Among them, triangular silver nanoplates (AgNPTs) exhibit strong field-enhancement and spectral tunability, ...

In-Fiber Graphene-hBN Polarizer With Enhanced Performance and Bandwidth

Graphene and hBN as two-dimensional materials with excellent optical properties can be combined with other materials. In this paper, graphene and hBN is sequentially deposited on the surface of the silicon-core fiber to serve as transverse ...

High performance thin-film lithium niobate modulator on a silicon substrate using periodic capacitively loaded traveling-wave electrode

Thin-film lithium niobate (TFLN) based traveling-wave modulators maintain simultaneously excellent performances, including large modulation bandwidth, high extinction ratio, low optical loss, and high modulation efficiency. Nevertheless, th...

Hg Isotopes and Enhanced Hg Concentration in the Meishan and Guryul Ravine Successions: Proxies for Volcanism Across the Permian-Triassic Boundary

High-resolution organic carbon isotope (δ13C), Hg concentration and Hg isotopes curves are presented for the Permian-Triassic boundary (PTB) sections at Guryul Ravine (India) and Meishan D (China). The total organic carbon (TOC)-normalized ...

Ecological correlates of extinction risk and persistence of direct-developing stream-dwelling frogs in Mesoamerica

Understanding the threats to wildlife across space and time is essential for developing effective conservation strategies. In Mesoamerica (i.e., the region that extends from Central Mexico to the most southern point in Panama) at least 40% ...

Astronomy and Astrophysics

The distribution of interstellar extinction has been mapped over the whole sky, using all available spectral and photometric data.The colour excess distribution is modelled as a function of galactic latitude, longitude and distance within a...

Three-Dimensional Physical and Optical Characteristics of Aerosols over Central China from Long-Term CALIPSO and HYSPLIT Data

Aerosols greatly influence global and regional atmospheric systems, and human life. However, a comprehensive understanding of the source regions and three-dimensional (3D) characteristics of aerosol transport over central China is yet to be...

Revealing the Widespread Bias of Extinction Risk in the Antarctic and the Southern Ocean.

Research Frontiers in the Field of Agricultural Resources and the Environment

From the perspective of project and paper datasets, research frontier recognition in the field of agricultural resources and the environment using the Latent Dirichlet Allocation (LDA) topic extraction model was studied. By combining the wi...

Phylogenetic evidence that migratory behavior increases ungulate extinction rates.
