An example of nonsymmetric semi-classical form of class s=1; generalization of a case of Jacobi sequence

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
We give explicitly the recurrence coefficients of a nonsymmetric semi-classical sequence of polynomials of class s=1. This sequence generalizes the Jacobi polynomial sequence, that is, we give a new orthogonal sequence {Pˆn(α,α+1)(x,μ)}, where μ is an ...

Pitardia resurrected: A new member of subtribe Menthinae (Lamiaceae)

open access: yesTAXON, EarlyView.
Abstract Despite tremendous progress towards clarifying phylogenetic relationships within the mint family (Lamiaceae), uncertainty remains regarding relationships among some major clades as well as the proper placement of some genera. While researching the genus Nepeta, a species from northeastern Morocco, N.

In situ monitoring of cell adhesion kinetics using label‐free optical biosensors: Evaluating anticancer potential and selectivity of natural compounds

open access: yesVIEW, EarlyView.
The limitations of conventional techniques hinder the identification of natural compounds with anticancer potential in terms of speed, throughput, sensitivity, and capability of continuous monitoring of relevant biological effects. Novel label‐free optical biosensors represent new opportunities in the discovery of drug candidates, eliminating these ...

Important areas at sea for adult loggerhead sea turtles in the Mediterranean Sea: satellite tracking corroborates findings from potentially biased sources [PDF]

open access: yes, 2018
Sea turtle populations worldwide suffer from reduced survival of immatures and adults due to fishery bycatch. Unfortunately, information about the whereabouts of turtles outside the breeding habitat is scarce in most areas, hampering the development of ...

Brain‐RetinaNet: Detection of Brain Tumour Using an Improved RetinaNet in Magnetic Resonance Imaging

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Brain tumours disrupt the normal functioning of the brain and, if left untreated, can invade surrounding tissues, blood vessels, and nerves, posing a severe threat. Consequently, early detection is crucial to prevent tragic outcomes. Distinguishing brain tumours through manual detection poses a significant challenge given their diverse ...

Time‐Domain Computation of Propagation Characteristics of Partial Discharge in Cross‐Linked Polyethylene High‐Voltage Cable Incorporating Modified Frequency‐Dependent Parameters

open access: yesHigh Voltage, EarlyView.
ABSTRACT The propagation characteristics of partial discharge (PD) in cables impact PD detection sensitivity, defect localisation accuracy and defect severity evaluation. Currently, the effects of semiconducting materials' frequency‐dependent properties and corrugated aluminium sheath structures on PD signal propagation in high‐voltage (HV) cables ...
