Sobre la parametrización de cónicas con rotación (la manera fácil) (On parameterization of conics with rotation (the easy way))

Revista Digital Matemática, Educación e Internet
Se presentan algunas parametrizaciones usuales (trigonométricas y racionales) de las cónicas en posición estándar y algunas aplicaciones. Para cónicas con rotación en la que solo interesa una parametrización trigonométrica o una racional, se presentan ...

A gradient-type deformation of conics and a class of Finslerian flows

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2017
The aim of this paper is to produce new examples of Riemannian and Finsler structures having as model a scalar deformation of conics inspired by the scaling transformation.

Real circles tangent to 3 conics

, 2023
In this paper we study circles tangent to conics. We show there are generically 184 complex circles tangent to three conics in the plane and we characterize the real discriminant of the corresponding polynomial system.

Establishment of a humanized patient‐derived xenograft mouse model of high‐grade serous ovarian cancer for preclinical evaluation of combination immunotherapy

Molecular Oncology, EarlyView.
We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...

Flow Enabled Target Capture Halbach‐based magnetic enrichment increases circulating tumor cell capture from blood in metastatic cancer patients

Molecular Oncology, EarlyView.
Pair‐wise comparison of the CellSearch and FETCH enrichment technologies for circulating tumor cells (CTCs) from metastatic breast, prostate, and small cell lung cancer patients shows an increased capture of CTCs using FETCH enrichment. The clinical implementation of circulating tumor cells (CTCs) as a predictive tool for therapy efficacy in the ...

Source altitudes and heating properties of electron conics observed at high altitudes by the Arase satellite

Earth, Planets and Space
Electron conics are a distinct type of electron distribution observed in Earth’s magnetosphere, characterized by enhanced fluxes of upgoing electrons at several-keV energies, particularly in the auroral acceleration region.

Problems of shape characterization and comparison in bryophytes

Acta Societatis Botanicorum Poloniae, 2014
Shapes of leaves of two liverwort species, viz. Lophozia ventricosa and Lophozia silvicola, were characterized by means of three different methods: polar coordinates, conics, and Fourier series.

Triads of Conics Associated with a Triangle

, 2022
We revisit constructions based on triads of conics with foci at pairs of vertices of a reference triangle. We find that their 6 vertices lie on well-known conics, whose type we analyze. We give conditions for these to be circles and/or degenerate. In the

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

FEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

A Study of Current Driven Electrostatic Instability on the Auroral Zone [PDF]

Journal of Astronomy and Space Sciences, 1986
According to recent satellite observations, strong ion transverse acceleration to the magnetic field(ion conics) has been known. The ion conics may be a result of electrostatic waves frequently observed on the auroral zone.
