Dammarenediol II enhances etoposide‐induced apoptosis by targeting O‐GlcNAc transferase and Akt/GSK3β/mTOR signaling in liver cancer

open access: yesMolecular Oncology, EarlyView.
Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...

International Taxation in an Era of Digital Disruption: Analyzing the Current Debate [PDF]

open access: yes, 2018
The “taxation of the digital economy” is currently at the top of the global international tax policymaking agenda. A core claim some European governments are advancing is that user data or user participation in the digital economy justifies a gross tax ...

International Tax Reform: Hearing Before the S. Comm. on Fin., 115th Cong., Oct. 3, 2017 (Statement of Itai Grinberg) [PDF]

open access: yes, 2017
Lowering the corporate income tax rate and moving to a territorial system are important to maintain U.S. prosperity and improve growth prospects for our economy. The U.S. cannot stand apart from corporate tax competition in a globalized economy.

High‐Throughput Screening and Interpretable Machine Learning for Rational Design of Bimetallic Catalysts for Methane Activation

open access: yesAdvanced Science, EarlyView.
ABSTRACT Methane's efficient catalytic removal is vital for sustainable development. Bimetallic catalysts, though promising for methane activation, pose a design challenge due to their complex compositional space. This work introduces an integrated framework that combines high‐throughput density functional theory (DFT) and interpretable machine ...

A Machine Learning Perspective on the Brønsted–Evans–Polanyi Relation in Water‐Gas Shift Catalysis on MXenes

open access: yesAdvanced Intelligent Discovery, EarlyView.
Machine learning predicts activation energies for key steps in the water‐gas shift reaction on 92 MXenes. Random Forest is identified as the most accurate model. Reaction energy and reactant LogP emerge as key descriptors. The approach provides a predictive framework for catalyst design, grounded in density functional theory data and validated through ...

Evaluation of a prototype interface for structured document retrieval [PDF]

open access: yes, 2003
Document collections often display either internal structure, in the form of the logical arrangement of document components, or external structure, in the form of links between documents.

Can boarding schools help looked after and vulnerable children improve academic attainment?

open access: yesBritish Educational Research Journal, EarlyView.
Abstract The education of children in statutory care, or at the edge of care, is a serious concern for governments and policymakers. How to promote educational opportunities for these children can involve challenging and often contentious proposals. In this paper, we study one proposal put into practice in England: the provision to children who are in ...

The beetle elytron plate: a lightweight, high-strength and buffering functional-structural bionic material

open access: yesScientific Reports, 2017
To investigate the characteristics of compression, buffering and energy dissipation in beetle elytron plates (BEPs), compression experiments were performed on BEPs and honeycomb plates (HPs) with the same wall thickness in different core structures and ...
