Liver organoids: modelling complexity in homeostasis and disease

open access: yesFEBS 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

A New Branching Rule to Solve the Capacitated Lot Sizing and Scheduling Problem with Sequence Dependent Setups

open access: yesTrends in Computational and Applied Mathematics, 2018
In this paper, we deal with the Capacitated Lot Sizing and Scheduling Problem with sequencedependent setup times and costs - CLSD model. More specifically, we propose a simple reformulation for the CLSD model that enables us to define a new branching ...

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

open access: yesFEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Optimizing bent branch numbers improves transpiration and crop water productivity of cut rose (Rosa hybrida) in greenhouse

open access: yesAgricultural Water Management
Bent branches are commonly utilized in cut roses to enhance commercial flower quality through increased nutrient production and biomass. However, the ideal number of bent branches concerning crop water productivity remains unknown.

The massless non-adjacent double off-shell scalar box integral — branch cut structure and all-order epsilon expansion

open access: yesJournal of High Energy Physics, 2023
We generalize the result of our recent paper on the massless single off-shell scalar box integral to the case of two non-adjacent end points off the light cone.

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

open access: yesFEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Research on topological structure and simulation of hybrid DC circuit breaker

open access: yesThe Journal of Engineering, 2019
At present, the hybrid DC circuit breaker (ABB company's Hybrid DC circuit breaker as the representative scheme) must be equipped with the radiator because of a long-time current passing through the power electronic devices in the load-control-switch ...

Probing the singularities of the Landau-Gauge gluon and ghost propagators with rational approximants

open access: yesJournal of High Energy Physics, 2023
We employ Padé approximants in the study of the analytic structure of the four-dimensional SU(2) Landau-gauge gluon and ghost propagators in the infrared regime.
