3SD: Rotational symmetry single‐shot denoising in fluorescence microscopy

Journal of Microscopy, EarlyView.
Abstract Image noise is a fundamental problem in fluorescence microscopy analysis, especially in live cell imaging applications where the number of detected photons is limited due to low power of excitation lasers to prevent phototoxicity during extended imaging experiments.

Postperihelion Cometary Activity on the Outer Main-belt Asteroid 2005 XR132

The Planetary Science Journal
We report comet-like activity on the outer main-belt asteroid 2005 XR _132 discovered by the Lulin One-meter Telescope in early 2021 April. A series of follow-up observations were triggered to characterize the morphology and brightness variation of 2005 ...

Digital range of motion analysis is sensitive to subjective steps in joint model construction

Journal of Anatomy, EarlyView.
A systematic sensitivity analysis of a six degree‐of‐freedom range of motion (ROM) analysis workflow was conducted to evaluate how variation in the subjective steps of the reference pose assembly affects the determined viable poses in the ankle and tarsometatarsophalangeal III joints of Guinea fowl (Numida meleagris).

Doublecortin restricts neuronal branching by regulating tubulin polyglutamylation

Nature Communications
Doublecortin is a neuronal microtubule-associated protein that regulates microtubule structure in neurons. Mutations in Doublecortin cause lissencephaly and subcortical band heterotopia by impairing neuronal migration. We use CRISPR/Cas9 to knock-out the

Development of an Isoline Modeling Method for Extended Small Celestial Objects

Учёные записки Казанского университета: Серия Физико-математические науки
This article presents a method for modeling extended small celestial (ESC) objects, which are mainly cometary systems. Special attention was given to the possibility of analyzing their structure and physical properties in line with the modern theories of

Syrinx anatomy and vocalizations in New World vultures (Aves: Cathartidae): Implications for avian vocal evolution

Journal of Anatomy, EarlyView.
New World vultures are the only avian clade proposed to lack a syrinx and have been described as non‐vocal. Using dissection, diceCT, and histology, we demonstrate that cathartid vultures have novel syringeal features that form a syrinx and vocal characterization reveals that they produce more complex vocalizations than previously reported.

Proceedings of Pedestrian and Evacuation Dynamics 2016

, 2016
n a recent series of papers, we proposed a mathematical model for the dynamics of a group of interacting pedestrians. The model is based on a non-Newtonian potential, that accounts for the need of pedestrians to keep both their interacting partner and ...

Reconstructing the major skull myology of the giant stem‐amphibian Mastodonsaurus: A case study for early tetrapods

Journal of Anatomy, EarlyView.
We reconstruct the major cranial musculature of the giant stem amphibian Mastodonsaurus giganteus, revealing a differentiated jaw‐adductor system, a probable sesamoid pulley, and previously unrecognised muscles. This EPB‐based case study establishes an anatomical framework for modelling feeding in early tetrapods and supports interpretations of ...

Local Elites in Chile's Pisco Valley: Dispossession, Legal Mobilisation and Intertwined Citizenship

Journal of Agrarian Change, EarlyView.
ABSTRACT In countries in the Global South, citizenship is often closely tied to access to water and land ownership. In Latin America, the literature has primarily explored social mobilisation and identity reconfiguration in response to development‐driven processes of land and water dispossession affecting peasants, rural and Indigenous communities ...

Applications of solar radiation pressure dominated highly non-Keplerian trajectories around minor bodies [PDF]

, 2013
With the growing interest in the exploration and possible exploitation of small minor bodies, demonstrator missions to asteroids and comets are a trending topic in the research community.
