Using Period Analysis to Timely Assess and Predict 5-Year Relative Survival for Liver Cancer Patients From Taizhou, Eastern China

Introduction: While timely assessment of long-term survival for patients with liver cancer is essential for the evaluation of early detection and screening programs of liver cancer, those data are extremely scarce in China. We aimed to timely and accurately assess long-term survival for liver cancer patients in eastern China.Methods: Patients diagnosed with liver cancer during 2004-2018 from four

The Influence of pH on the Lipase Digestion of Nanosized Triolein, Diolein and Monoolein films

Herein we studied the processes at the liquid aqueous interface at pH 7 and 8.5 during Thermomyces lanuginosus lipase-catalyzed hydrolysis of nanosized tri-, di- and mono-olein films deposited on a planar substrate. By employing a combination of ellipsometry, QCM-D and ATR-FTIR, we were able to reveal the physical properties of the thin films at high time resolution throughout the initial hydratio

Development and characterization of photovoltaic tandem-junction nanowires using electron-beam-induced current measurements

Nanowires have many interesting properties that are of advantage for solar cells, such as the epitaxial combination of lattice-mismatched materials without plastic deformation. This could be utilized for the synthesis of axial tandem-junction nanowire solar cells with high efficiency at low material cost. Electron-beam-induced current measurements have been used to optimize the performance of sing

Realization of axially defined GaInP/InP/InAsP triple-junction photovoltaic nanowires for high-performance solar cells

III-V semiconductor-based planar multi-junction solar cells synthesized to match the solar spectrum, increase absorption, and reduce thermalization loss are today's world-record efficiency solar cells. Realizing similarly performing multi-junction III-V nanowire (NW) solar cells would require significantly less material and is more sustainable at lower cost than planar solar cells. The NW geometry

Reduction of primary graft dysfunction using cytokine adsorption during organ preservation and after lung transplantation

Despite improvements, lung transplantation remains hampered by both a scarcity of donor organs and by mortality following primary graft dysfunction (PGD). Since acute respiratory distress syndrome (ARDS) limits donor lungs utilization, we investigated cytokine adsorption as a means of treating ARDS donor lungs. We induced mild to moderate ARDS using lipopolysaccharide in 16 donor pigs. Lungs were

Warming response of peatland CO2 sink is sensitive to seasonality in warming trends

Peatlands have acted as net CO2 sinks over millennia, exerting a global climate cooling effect. Rapid warming at northern latitudes, where peatlands are abundant, can disturb their CO2 sink function. Here we show that sensitivity of peatland net CO2 exchange to warming changes in sign and magnitude across seasons, resulting in complex net CO2 sink responses. We use multiannual net CO2 exchange obs

Recalibrated responses needed to a global research landscape in flux

When engaging in international collaboration, researchers and research institutions have to relate to a great range of differences in legislation, scientific practices, incentive systems, and cultural norms. The research landscape has become even more complex in the last decade, and the gray zones at the intersections of a diverse set of institutional contexts may be used to push boundaries. The f

On-line compositional measurements of AuAg aerosol nanoparticles generated by spark ablation using optical emission spectroscopy

Spark ablation is an established technique for generating aerosol nanoparticles. Recent demonstrations of compositional tuning of bimetallic aerosols have led to a demand for on-line stoichiometry measurements. In this work, we present a simple, non-intrusive method to determine the composition of a binary AuAg nanoparticle aerosol on-line using the optical emission from the electrical discharges.

Participation of alkali and sulfur in ammonia combustion chemistry : Investigation for ammonia/solid fuel co-firing applications

Ammonia (NH3) is a promising carbon-free energy carrier. Co-firing of ammonia in solid fuel-fired facilities is a feasible solution to reduce carbon dioxide (CO2) emissions. Solid fuels, such as coal and biomass, contain various trace elements, such as alkali metals and sulfur, which are released to the gas phase during combustion. Experimental characterization and modeling are used to study the p

The implementation of systematic monitoring of cognition in children with cerebral palsy in Sweden and Norway

PURPOSE: Children with cerebral palsy (CP) are at risk of cognitive impairments and need to be cognitively assessed to allow for individualized interventions, if applicable. Therefore, a systematic protocol for the follow-up of cognition in children with CP, CP Cog, with assessments offered at five/six and 12/13 years of age, was developed. This report presents and discusses assessment practices i

A strategic canvas for degrowth: In dialogue with Erik Olin Wright

This chapter articulates a strategic canvas for degrowth, based on a dialogue with the work of Erik Olin Wright. It argues that degrowth strategies for social- ecological transformation need to combine several strategic approaches, reflecting the plurality of degrowth as a movement. To support the myriad of bottom-up alternatives that are already out there, degrowth actors should put a special emp

Disability, Justice and Freedom as Non-Domination

Disability scholars have recently proposed that republican theory is relevant to think about justice in relation to disability. Following in their footsteps, this article submits that the republican conception of freedom as non-domination provides a fresh angle to legitimise disability rights in terms of justice and prevent their interpretation as charity or privileges. This proposition takes its
