Investigation of factors in improving Agrobacterium-mediated gene transfer in Ruellia tuberosa L. and evaluation of α-glucosidase inhibitory activity in established hairy roots

open access: yesNotulae Botanicae Horti Agrobotanici Cluj-Napoca, 2022
Ruellia tuberosa (family Acanthaceae) is widely known in traditional medicine in Asian countries for the treatment of diabetes and other diseases. Its roots were demonstrated to possess a hypoglycemic ability in diabetic animal models. In this study, an

Using Geometry to Select One Dimensional Exponential Families That Are Monotone Likelihood Ratio in the Sample Space, Are Weakly Unimodal and Can Be Parametrized by a Measure of Central Tendency

open access: yesEntropy, 2014
One dimensional exponential families on finite sample spaces are studied using the geometry of the simplex Δn°-1  and that of a transformation Vn-1 of its interior.

Model Checking in Bits and Pieces [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2013
Fully automated verification of concurrent programs is a difficult problem, primarily because of state explosion: the exponential growth of a program state space with the number of its concurrently active components.

Small area estimation with spatially varying natural exponential families [PDF]

open access: yesJournal of Statistical Computation and Simulation, 2020
Two-stage hierarchical models have been widely used in small area estimation to produce indirect estimates of areal means. When the areas are treated exchangeably and the model parameters are assumed to be the same over all areas, we might lose the efficiency in the presence of spatial heterogeneity.

Synthesis and Antiproliferative Activity against Cancer Cells of Indole-Aryl-Amide Derivatives

open access: yesMolecules, 2022
Indoles constitute a large family of heterocyclic compounds widely occurring in nature which are present in a number of bioactive natural and synthetic compounds, including anticancer agents or atypical opioid agonists. As a result, exponential increases

Visualizing probabilistic models in Minkowski space with intensive symmetrized Kullback-Leibler embedding

open access: yesPhysical Review Research, 2020
We show that the predicted probability distributions for any N-parameter statistical model taking the form of an exponential family can be explicitly and analytically embedded isometrically in a N+N-dimensional Minkowski space.

bamlss: A Lego Toolbox for Flexible Bayesian Regression (and Beyond)

open access: yesJournal of Statistical Software, 2021
Over the last decades, the challenges in applied regression and in predictive modeling have been changing considerably: (1) More flexible regression model specifications are needed as data sizes and available information are steadily increasing ...

Bayesian approach to cubic natural exponential families [PDF]

open access: yesStatistics & Probability Letters, 2013
For a natural exponential family (NEF), one can associate in a natural way two standard families of conjugate priors, one on the natural parameter and the other on the mean parameter. These families of conjugate priors have been used to establish some remarkable properties and characterization results of the quadratic NEF's.

Telemedicine Competencies in Family Medicine Clerkships: A CERA Study [PDF]

open access: yes, 2023
Background: While the Association of American Medical Colleges (AAMC) designated cross-disciplinary telemedicine competencies, curricular implementation is at disparate stages across medical schools and with significant curricular gaps.
