Parametric Frailty Analysis in Presence of Collinearity: An Application to Assessment of Infant Mortality

open access: yesMathematics, 2022
This paper analyzes the time to event data in the presence of collinearity. To address collinearity, the ridge regression estimator was applied in multiple and logistic regression as an alternative to the maximum likelihood estimator (MLE), among others.

Hox genes in the coordination of embryonic development. Model of hourglass in the description of vertebrate ontogenesis

open access: yesJournal of Education, Health and Sport, 2021
The paper analyzes the role of HOX genes in the processes of embryonic development of vertebrates. Based on the analysis, it is concluded that HOX genes are the most important regulators of embryonic development.

Circumnavigating collinear superspace [PDF]

open access: yesJournal of High Energy Physics, 2020
AbstractIn this paper, we extend the collinear superspace formalism to include the full range of$$ \mathcal{N} $$N= 1 supersymmetric interactions. Building on the effective field theory rules developed in a companion paper —Navigating Collinear Superspace[1] — we construct collinear superspace Lagrangians for theories with non-trivialF- andD-term ...

Controlling for body size leads to inferential biases in the biological sciences

open access: yesEvolution Letters, 2020
Many traits correlate with body size. Studies that seek to uncover the ecological factors that drive evolutionary responses in traits typically examine these responses relative to associated changes in body size using multiple regression analysis ...

Exploring Efficient Methods for Using Multiple Spectral Reflectance Indices to Establish a Prediction Model for Early Drought Stress Detection in Greenhouse Tomato

open access: yesHorticulturae, 2023
Early detection of drought stress in greenhouse tomato (Solanum lycopersicum) is an important issue. Real-time and nondestructive assessment of plant water status is possible by spectroscopy.

Collinear superspace

open access: yesPhysical Review D, 2016
This letter provides a superfield based approach to constructing a collinear slice of $\mathcal{N}$ = 1 superspace. The strategy is analogous to integrating out anti-collinear fermionic degrees-of-freedom as was developed in the context of soft-collinear effective theory.

ISOSCELES TRIANGLES ON THE SIDES OF A TRIANGLE

open access: yesHuman Research in Rehabilitation, 2019
Famous construction of Fermat-Toricelly point of a triangle leads to the question is there a similar way to construct other isogonic centers of a triangle in a similar way.

Collinear Points in Permutations [PDF]

open access: yesAnnals of Combinatorics, 2005
Consider the following problem: how many collinear triples of points must a transversal of (Z/nZ)^2 have? This question is connected with venerable issues in discrete geometry. We show that the answer, for n prime, is between (n-1)/4 and (n-1)/2, and consider an analogous question for collinear quadruples.

Visual perception of collinearity [PDF]

open access: yesPerception & Psychophysics, 2002
In a metrical space, there exists an intimate relation between collinearity and parallelity. In particular, in a Riemannian space collinearity is just a special case of parallelity. Is this true for visual space as well? We investigated the visual perception of collinearity by having subjects align two bars in the horizontal plane at eye height.

Navigating collinear superspace [PDF]

open access: yesJournal of High Energy Physics, 2020
AbstractWe introduce a new set of effective field theory rules for constructing Lagrangians with$$ \mathcal{N} $$N= 1 supersymmetry in collinear superspace. In the standard superspace treatment, superfields are functions of the coordinates$$ \left({x}^{\mu },{\theta}^{\alpha },{\theta}^{\dagger \overset{\cdot }{\alpha }}\right) $$xμθαθ†α⋅, and ...
