Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

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.

Proximal Branching of the Anterior Tibial Artery From the Popliteal Artery Increases the Risk of Vascular Injury During Total Knee Arthroplasty: A Retrospective Analysis Using Preoperative Magnetic Resonance Imaging and Intraoperative Findings

open access: yesGeriatric Orthopaedic Surgery & Rehabilitation, 2022
Introduction Arterial injury following total knee arthroplasty (TKA) can be life-threatening. There are some anatomical variations in the popliteal artery (PA) and its branches.

Branch and cut methods for network optimization

open access: yesMathematical and Computer Modelling, 2001
This paper contains a survey on the use of the Branch and Cut technique for solving network related combinatorial optimization problems. After an introductory section, a description in general terms is given of the Branch and Cut methodology and of the ``separation problem'', including also a discussion on advantages and disadvantages of the technique.

A branch‐and‐cut algorithm for the Team Orienteering Problem [PDF]

open access: yesInternational Transactions in Operational Research, 2017
AbstractThe Team Orienteering Problem aims at maximizing the total amount of profit collected by a fleet of vehicles while not exceeding a predefined travel time limit on each vehicle. In the last years, several exact methods based on different mathematical formulations were proposed.

AAA+ protein unfoldases—the Moirai of the proteome

open access: yesFEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Location-Routing Problem of Emergency Facilities under Uncertain Demand by Branch-Price and Cut

open access: yesJournal of Mathematics, 2021
This paper studies the location-routing problem of emergency facilities with time window under demand uncertainty. We propose a robust mathematical model in which uncertain requirements are represented by two forms: the support set defined by cardinal ...
