A Frontier Model for Landscape Ecology: The Tapir in Honduras [PDF]

open access: yes
We borrow a frontier specification from the econometrics literature to make inferences about the tolerance of the tapir to human settlements. We estimate the width of an invisible band surrounding human settlements which would act as a frontier or ...

Effects of Human Choices on Characteristics of Urban Ecosystems [PDF]

open access: yes, 2007
Most urban ecology in cities remains an ecology in cities rather than an ecology of cities. Accomplishing the latter requires the inclusion of humans within the concept of ecosystem, both how humans alter the properties of urban ecosystems and how ...

Bionic Nanostructures Create Mechanical Signals to Mediate the Composite Structural Bone Regeneration Through Multi‐System Regulation

open access: yesAdvanced Science, EarlyView.
Inspired by the structural and functional characteristics of bone, bionic nanomaterials combined with nanotechnology can more accurately replicate stem cell niches, enabling the design of bone tissue engineering scaffolds with diverse nanoscale properties to promote stem cell migration, proliferation, and differentiation. This precise control over stem

Geography, Institutions and Human Development: A Cross-Country Investigation Using Bayesian Model Averaging [PDF]

open access: yes
This paper examines the role of long standing institutions – identified through geography, disease ecology, colonial legacy, and some direct measures of political and economic governance – on human development and its non income components across ...

Naturalizing ethics [PDF]

open access: yes, 2007
In this essay we provide (1) an argument for why ethics should be naturalized, (2) an analysis of why it is not yet naturalized, (3) a defense of ethical naturalism against two fallacies—Hume’s and Moore’s—that ethical naturalism allegedly commits, and ...

Mixed‐Dimensional Floating Gate Phototransistors for Mixed‐Modal In‐Sensor Reservoir Computing

open access: yesAdvanced Science, EarlyView.
Designing bio‐inspired multisensory neuromorphic devices holds significant importance for low‐power and high‐efficiency computing. Here, the authors introduce a floating‐gate phototransistor based on the mixed‐dimensional heterostructure of 0D‐CsPbBr3 QDs and 2D‐MoS2 few layers.

Structural Variations Associated with Adaptation and Coat Color in Qinghai‐Tibetan Plateau Cattle

open access: yesAdvanced Science, EarlyView.
This study reveals the landscape of structural variants in Qinghai‐Tibetan Plateau cattle through long‐read sequencing. Discoveries include metabolic and oxygen‐regulation gene variants, along with a 2‐Mb KIT‐containing inversion and translocations responsible for cattle gray coat. These findings highlight the significant role of structural variants in
