Oldest well‐preserved euprimate petrosal, from the early Eocene of India (Vastan Lignite Mine, Gujarat)

The Anatomical Record, EarlyView.
Abstract An exquisitely preserved, isolated partial petrosal with associated fragmentary stapes is described from the Vastan Lignite Mine (Gujarat, India), dated to the early Eocene (~54.5 Ma). Several anatomical traits (e.g., large petrosal plate; posterolateral entry of the internal carotid artery to the tympanic cavity; bony tubes surrounding the ...

Sparse maximum likelihood estimation of regression models

Canadian Journal of Statistics, EarlyView.
Abstract For regression model selection and estimation, we study a small set of candidate models of maximum likelihood from which all information criteria such as the Akaike information criterion (AIC) and the Bayesian information criterion (BIC) choose their models.

Freshwater diversity responses to ecosystem ageing

Ecography, EarlyView.
Ecosystem age is a key driver of biodiversity patterns, yet its effects may arise from different temporal processes of ecosystem history. In reservoir ecosystems, community trajectories are shaped not only by succession following dam construction but also by recurrent management‐driven disturbances such as drawdowns.

Optical flow estimation using the Fisher-Rao metric [PDF]

, 2021
The optical flow in an event camera is estimated using measurements in the Address Event Representation (AER). Each measurement consists of a pixel address and the time at which a change in the pixel value equalled a given fixed threshold.

How Multiple Streams Influence Agenda‐Setting for Water Reuse in Swiss Substates

Environmental Policy and Governance, EarlyView.
ABSTRACT As climate change creates significant challenges for both the environment and society, potential mitigation and adaptation solutions are widely discussed. Yet, neither challenges nor their potential solutions automatically reach the political agenda or lead to a policy decision.

On a general matrix-valued unbalanced optimal transport problem

European Journal of Applied Mathematics
We introduce a general class of transport distances $\mathrm {WB}_{\Lambda }$ over the space of positive semi-definite matrix-valued Radon measures $\mathcal {M}(\Omega, \mathbb {S}_+^n)$ , called the weighted Wasserstein–Bures distance ...

Cutaneous Leiomyosarcoma of the Head and Neck: Appreciation of a More Indolent Biological Behavior and Implications for Its Management

Head &Neck, EarlyView.
ABSTRACT Background Leiomysosarcoma (LMS) is generally associated with high metastatic potential and poor survival. Cutaneous LMS (cLMS) has been considered a different entity with more indolent biological behavior. Methods A narrative review was performed to assess the biological behavior of cLMS, with special attention for the head and neck location.

GW190814: Gravitational Waves from the Coalescence of a 23 Solar Mass Black Hole with a 2.6 Solar Mass Compact Object

The Astrophysical Journal Letters, 2020
We report the observation of a compact binary coalescence involving a 22.2–24.3 M _⊙ black hole and a compact object with a mass of 2.50–2.67 M _⊙ (all measurements quoted at the 90% credible level).

Remote Sensing for Irrigation Water Management—The State of the Art and Prospects for Near‐Future Operations

Irrigation and Drainage, EarlyView.
ABSTRACT A recent UN report describes many regions as facing ‘water bankruptcy,’ a condition in which available water resources can no longer meet existing demands. In practice, this means irrigation will likely bear the greatest burden of future water‐use reductions, a complicated and fraught decision to make given its critical role in food security ...
