Publicly available datasets of breast histopathology H&E whole-slide images: A scoping review [PDF]

arXiv, 2023
Advancements in digital pathology and computing resources have made a significant impact in the field of computational pathology for breast cancer diagnosis and treatment. However, access to high-quality labeled histopathological images of breast cancer is a big challenge that limits the development of accurate and robust deep learning models.

Dynamic Arctic weather variability and connectivity [PDF]

arXiv, 2023
The rapidly shrinking Arctic sea ice is changing weather patterns and disrupting the balance of nature. Dynamics of Arctic weather variability (WV) plays a crucial role in weather forecasting and is closely related to extreme weather events.

Arctic connectivity: A frugal approach to infrastructural development [PDF]

arXiv, 2021
As the Arctic is heating up, so are efforts to strengthen connectivity within the region, but also to enhance the connections from remote settlements to the global networks of trade as well as sociality. With global interest in the Arctic on the rise, it becomes increasingly relevant to ensure that investments in arctic infrastructure actually serve ...

Sea-level and summer season orbital insolation as drivers of Arctic sea-ice [PDF]

arXiv, 2021
The sea-ice cover of the Arctic Ocean is an important element of the climate and ocean system in the Northern Hemisphere as it impacts albedo, atmospheric pressure regimes, CO2-exchange at the ocean/atmosphere interface as well as the North Atlantic freshwater budget and thermohaline circulation [1].

Limit shape phase transitions: a merger of arctic circles [PDF]

, 2022
We consider a free fermion formulation of a statistical model exhibiting a limit shape phenomenon. The model is shown to have a phase transition that can be visualized as the merger of two liquid regions - arctic circles. We show that the merging arctic circles provide a space-time resolved picture of the phase transition in lattice QCD known as Gross ...

When Will Arctic Sea Ice Disappear? Projections of Area, Extent, Thickness, and Volume [PDF]

arXiv, 2022
Rapidly diminishing Arctic summer sea ice is a strong signal of the pace of global climate change. We provide point, interval, and density forecasts for four measures of Arctic sea ice: area, extent, thickness, and volume. Importantly, we enforce the joint constraint that these measures must simultaneously arrive at an ice-free Arctic.

The tipping times in an Arctic sea ice system under influence of extreme events [PDF]

, 2020
In light of the rapid recent retreat of Arctic sea ice, the extreme weather events triggering the variability in Arctic ice cover has drawn increasing attention. A non-Gaussian $\alpha$-stable L\'evy process is thought to be an appropriate model to describe such extreme event. The maximal likely trajectory, based on the nonlocal Fokker-Planck equation,

Climate Models Underestimate the Sensitivity of Arctic Sea Ice to Carbon Emissions [PDF]

arXiv, 2023
Arctic sea ice has steadily diminished as atmospheric greenhouse gas concentrations have increased. Using observed data from 1979 to 2019, we estimate a close contemporaneous linear relationship between Arctic sea ice area and cumulative carbon dioxide emissions. For comparison, we provide analogous regression estimates using simulated data from global

Arctic curves for paths with arbitrary starting points: a tangent method approach [PDF]

J. Phys. A: Math. Theor. 51 355201 (2018), 2018
We use the tangent method to investigate the arctic curve in a model of non-intersecting lattice paths with arbitrary fixed starting points aligned along some boundary and whose distribution is characterized by some arbitrary piecewise differentiable function.

Arctic Curves in path models from the Tangent Method [PDF]

, 2017
Recently, Colomo and Sportiello introduced a powerful method, known as the \emph{Tangent Method}, for computing the arctic curve in statistical models which have a (non- or weakly-) intersecting lattice path formulation. We apply the Tangent Method to compute arctic curves in various models: the domino tiling of the Aztec diamond for which we recover ...
