Which wind turbine types are needed in a cost‐optimal renewable energy system?

open access: yesWind Energy
Previous research has indicated that wind power plants can be designed to have less‐variable power generation, thereby mitigating the drop in economic value that typically occurs at high wind power penetration rates.

Black Hole Thermodynamics and Heavy Fermion Metals

open access: yes, 2010
Heavy fermion alloys at critical doping typically exhibit non-Fermi-liquid behavior at low temperatures, including a logarithmic or power law rise in the ratio of specific heat to temperature as the temperature is lowered. Anomalous specific heat of this

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 ...

The acute effects of post-activation potentiation on sport-climbing specific power exercises

open access: yesJournal of Education, Health and Sport, 2018
The effect of performing biomechanically similar exercises in such order that resistance exercise was followed by plyometric, power or speed exercise is a temporal increase in power and force production.

The expressive power of implicit specifications

open access: yesTheoretical Computer Science, 1991
We investigate the expressive power of implicit specifications of concurrent systems. That is, we consider specifications \(S\) specifying a system \(P\) not directly, but rather in combination with a given environment. Formally, we shall represent the environment as a \(CCS\) context of the form \((A\mid[\;][\Phi])\setminus L\), where \(A\) is a ...

Development of new sealed bipolar lead-acid battery [PDF]

open access: yes
New light weight composite bipolar plates which can withstand the corrosive environment of the lead acid battery have made possible the construction of a sealed bipolar lead acid battery that promises to achieve very high specific power levels and ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Krypton Ion Thruster Performance [PDF]

open access: yes
Preliminary data were obtained from a 30 cm ion thruster operating on krypton propellant over the input power range of 0.4 to 5.5 kW. The data presented are compared and contrasted to the data obtained with xenon propellant over the same input power ...

Siting nuclear power plants in California: the near-term alternatives [PDF]

open access: yes, 1973
There are many issues presently being debated concerning the generation and utilization of electric power in California. Some are peculiar to a specific area, such as the level of air quality and how it is influenced by fossil-fuel power plants.

Identification of serum protein biomarkers for pre‐cancerous lesions associated with pancreatic ductal adenocarcinoma

open access: yesMolecular Oncology, EarlyView.
This work identified serum proteins associated with pancreatic epithelial neoplasms (PanINs) and early‐stage PDAC. Proteomics screens assessed genetically engineered mice with abundant PanINs, KPC mice (Lox‐STOP‐Lox‐KrasG12D/+ Lox‐STOP‐Lox‐Trp53R172H/+ Pdx1‐Cre) before PDAC development and also early‐stage PDAC patients (n = 31), compared to benign ...
