LDAcoop: Integrating non‐linear population dynamics into the analysis of clonogenic growth in vitro

open access: yesMolecular Oncology, EarlyView.
Limiting dilution assays (LDAs) quantify clonogenic growth by seeding serial dilutions of cells and scoring wells for colony formation. The fraction of negative wells is plotted against cells seeded and analyzed using the non‐linear modeling of LDAcoop.

TECHNIQUE AND SOFTWARE FOR PROJECT PROPOSALS EXPERT ASSESSMENT OF AVIATION AND ROCKETRY PRODUCTS

open access: yesНаучный вестник МГТУ ГА, 2018
The essence of an expert assessment as a scientific method is a rational organization of experts analyzing the problem from a quantitative evaluation of judgments and results processing. A generalized opinion of the expert group is taken as the solution.

Vortex-lift roll-control device [PDF]

open access: yes, 1979
A wing is described for aircraft of cropped, arrow-type planform with thin leading and side edges. The wing has a pivotable tip to alter the crop angle of the wing during flight.

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 ...

Analysis of calculation results of lift and drag forces for several wings using nonlinear section data

open access: yesAviation, 2005
Calculation results for 11 different finite span wings are presented. Calculations were made by a combination of a numerical solution of lifting line theory with a technique developed to evaluate nonlinear section lift data.

Flexible Flaps Inspired by Avian Feathers Can Enhance Aerodynamic Robustness in low Reynolds Number Airfoils

open access: yesFrontiers in Bioengineering and Biotechnology, 2021
Unlike rigid rotors of drones, bird wings are composed of flexible feathers that can passively deform while achieving remarkable aerodynamic robustness in response to wind gusts.

Left threatened by Right: political intergroup bias in the contemporary Italian context. [PDF]

open access: yes, 2019
Using different evaluation targets (i.e., politicians’ pictures, ideological words, items referring to features attributed to political ingroup/outgroup) we characterized the intergroup bias among political groups in the Italian context (Study 1-2-3) and

Naked cuticle is essential for Drosophila wing development beyond Wingless signaling

open access: yesFEBS Open Bio, EarlyView.
Naked cuticle (Nkd), a Wnt signaling inhibitor, assumes extensive roles in Drosophila wing development. Overexpressing Nkd causes smaller, crumpled wings, while also perturbing multiple signaling pathways and developmental genes. A specific region (R1S) is critical for Nkd's function as a signaling integrator, offering new insights for studying its ...

Basic research in wake vortex alleviation using a variable twist wing [PDF]

open access: yes, 1981
The variable twist wing concept was used to investigate the relative effects of lift and turbulence distribution on the rolled up vortex wake. Several methods of reducing the vortex strength behind an aircraft were identified.
