Some interesting series arising from the power series expansion of (sin-1x)q

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2005
Starting from the power series expansions of (sin-1x)q, for 1≤p≤4, formulae are obtained for the sum of several infinite series. Some of these evaluations involve ζ(3).

Time-dependent reliability analysis with series expansion and equivalent-plane approach [PDF]

open access: yesMechanical Sciences
Developing highly efficient and accurate methodologies is a central challenge in the field of time-dependent reliability. In this paper, a time-dependent-reliability analysis method that couples series expansion with the equivalent-plane approach is ...

Ubiquitination of secretory granules promotes their crinophagic degradation in Drosophila

open access: yesFEBS Letters, EarlyView.
Ubiquitination of secretory granules in Drosophila larval salivary glands is a critical molecular trigger for crinophagy, the lysosomal degradation of unreleased, or low‐quality granules. The E3 ubiquitin ligase Cnot4 is recruited to the surface of secretory granules to induce crinophagy.

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 ...

Applying Biomedical Ontologies on Semantic Query Expansion

open access: yes, 2009
*1- Introduction* The interpretation of a question (or information need) depends, among other things, of a series of lexicalsemantic relations that complement and help the cognitive process of answering that information need.

Fast computation of sine/cosine series coefficients of associated Legendre function of arbitrary high degree and order

open access: yesJournal of Geodetic Science, 2018
In order to accelerate the spherical/spheroidal harmonic synthesis of any function, we developed a new recursive method to compute the sine/cosine series coefficient of the 4π fully- and Schmidt quasi-normalized associated Legendre functions.

Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

open access: yesMolecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

Analysis of the ratio between the plasticity of clay and the expansion capacity by changes in humidity and temperature

open access: yes, 2021
. Clay is a cohesive material that varies in volume due to changes in humidity and temperature. Its behavior is studied with physical and geotechnical characterization of the material.

Long Seasonal Cycle Modeling: the Case of Realized Volatility [PDF]

open access: yesStatistika: Statistics and Economy Journal, 2018
Time series with long seasonal periods are very common. Several methods have been proposed for modeling of long seasonal cycles, the most commonly used ones being those based on basis expansion. In this paper, we present and discuss these methods.
