Liver organoids: modelling complexity in homeostasis and disease

FEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Pathwise inequalities for local time : applications to skorokhod embeddings and optimal stopping [PDF]

, 2007
We develop a class of pathwise inequalities of the form H(B-t) >= M-t + F(L-t), where B-t is Brownian motion, L-t its local time at zero and M-t a local martingale.

A Multilabel Embedding-Based Framework for Predicting Short-Term Cross-Category Complaint Recurrence

Informatics
Public complaints exhibit strong spatiotemporal dependencies, where issues often propagate across categories within short timeframes, yet existing studies largely overlook cross-category recurrence and underutilize embedding representations for ...

The microbiome in human skin aging

FEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

Property A, partial translation structures and uniform embeddings in groups

, 2006
We define the concept of a partial translation structure T on a metric space X and we show that there is a natural C*-algebra C*(T) associated with it which is a subalgebra of the uniform Roe algebra C*u(X).

Deep MinCut: Learning Node Embeddings by Detecting Communities

, 2023
We present Deep MinCut (DMC), an unsupervised approach to learn node embeddings for graph -structured data. It derives node representations based on their membership in communities.

Spinors, embeddings and gravity

, 1988
This thesis is concerned with the theory of spinors, embeddings and everywhere invariance with applications to general relativity. The approach is entirely geometric with particular emphasis on the use of natural structures.

Finding Relatedness: pathways for detecting textual relatedness in the medieval scholastic corpus

Methodos
To show the importance of preparing historical editions as textual data first, while leaving presentation (whether in print or on the web) as a secondary down-stream task, this article identifies beneficial outcomes for research that can be achieved ...

Embedding-Based Music Emotion Recognition Using Composite Loss

IEEE Access, 2023
Most music emotion recognition approaches perform classification or regression that estimates a general emotional category from a distribution of music samples, but without considering emotional variations (e.g., happiness can be further categorised into
