Modelling the impact of Next Generation Access (NGA) on voice termination cost [PDF]

open access: yes
Termination of a telephone call can only be realized by the network operator of the receiving party. For this reason, the markets for fixed and mobile call termination are regulated ex-ante including price control.

A Soft Matrix Microenvironment Promotes Laterally Spreading Tumors via Oxidative Phosphorylation‐Dependent Cell Adhesion

open access: yesAdvanced Science, EarlyView.
Laterally spreading tumors (LSTs) are precancerous colorectal lesions characterized by a flat morphology. This study reveals a mechanochemical pathway through which a soft matrix microenvironment diminishes spatial constraints in intestinal adenomas. This process promotes deficiencies in tight junction proteins, mediated by the mechanoreceptor ADORA2B ...

Markets, Money and Ideology [PDF]

open access: yes
Marx's critique of Hegel is used to derive a demarcation criterion that sharply separates scientific knowledge from ideology, and interprets Hegelian methodology as fundamentally ideological.

ROS‐Responsive Nanobubbles for Dual‐Enhanced Ultrasound and Magnetic Resonance Imaging of Tumor Oxidative Stress

open access: yesAdvanced Science, EarlyView.
We report the development of biotinylated PEGylated bilirubin‐coated perfluoropentane (bt‐PEG‐BR@PFP) nanobubbles, a novel class of ROS‐activatable and dual‐modality contrast agents that amplify both ultrasound (US) and magnetic resonance imaging (MRI) signals in response to elevated ROS.

Nernstian Diagnostics of Imperfect Selectivity in Naphthalene Diimide‐Based Aqueous Organic Redox Flow Battery

open access: yesAdvanced Science, EarlyView.
Non‐ideal redox electrolytes still govern the Nernstian behavior of electrode potentials in aqueous organic redox flow batteries under operation. We utilized this effect to analytically predict two scenarios of battery performance degradation. ABSTRACT Aqueous organic redox flow batteries (AORFBs) enhance the sustainability of battery energy storage ...

Researching sustainable agriculture: The role of values in systemic science [PDF]

open access: yes, 2000
This paper presents a specific perspective on the science demarcation issue, the perspective of systemic science. A systemic science is a science that influences its own subject area.

One‐Dimensional RuIrTe Nanotubes with Amorphous Surface as a Highly Active and Stable Electrocatalyst Toward Oxygen Evolution Reaction in Acidic Media

open access: yesAdvanced Science, EarlyView.
A rational etching‐induced reconstruction strategy is demonstrated to fabricate one‐dimensional RuIrTe ternary nanotubes with a unique amorphous‐crystalline heterostructure. This hierarchical architecture synergistically optimizes mass transport and electronic configurations, delivering record‐breaking performance in proton exchange membrane water ...

Demarcating scientific medicine

open access: yesStudies in History and Philosophy of Science
Scientific medicine and homeopathy are interesting case studies for the ongoing project of demarcating science from pseudoscience. Much of the demarcation literature formulates abstract criteria for demarcating science from pseudoscience generally. In service of a more localist approach to the demarcation problem, I reconstruct a specific demarcating ...
