Dimensioning of Heliostat Components under Wind and Gravity Load: the Map Approach [PDF]

, 2008
Estimating annual optical performance of heliostats under realistic load is computationally very expensive as complex structural deformation and ray tracing calculations are necessary. An approach is presented that vastly accelerates these calculations

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

FEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Effect of Collaborative Utilization of Energy Storage and Wind Power on Wind Power Grid-connected and Carbon Emission

Chemical Engineering Transactions, 2017
In order to research the effect of collaborative utilization of energy storage and wind power on wind power grid- connected and carbon emission, this paper discussed the correlation between wind power output and load and effect of wind power connected ...

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Nonlinear swing dynamics of tower crane load subject to stochastic wind excitation: A CFD/CSD coupling approach.

PLoS ONE
With the expanding deployment of tower cranes in high-altitude environments, the dynamic interference of stochastic wind excitation on load swing has become a critical concern.

Improved Frequency Regulation Control Strategy of Wind Power Considering Random Fluctuation Characteristics of Source-Load

发电技术
ObjectivesLarge-scale wind power integration leads to a decrease in grid inertia, and the fluctuating power of wind turbines combined with random fluctuation of load under turbulent wind speed aggravates the frequency fluctuation in the power grid ...

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

Molecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Identification of Wind Load Exerted on the Jacket Wind Turbines from Optimally Placed Strain Gauges Using C-Optimal Design and Mathematical Model Reduction

Journal of Marine Science and Engineering
Wind turbine towers experience complex dynamic loads during actual operation, and these loads are difficult to accurately predict in advance, which may lead to inaccurate structural fatigue and strength assessment during the structural design phase ...

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

Molecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.
