Remarks on the Periodic Conformable Sturm–Liouville Problems

open access: yesComplexity, Volume 2023, Issue 1, 2023., 2023
The conformable Sturm–Liouville problem (CSLP), −x1−αpxx1−αy′x′=λρx−qxyx, for 0 < α ≤ 1, is studied under some certain conditions on the coefficients p, ρ, and q. According to an interesting idea proposed by P. Binding and H. Volkmer [Binding et al., 2012, Binding et al., 2013], we will derive how to reduce the periodic or antiperiodic (CSLP) to an ...

Non-oscillation of half-linear differential equations with periodic coefficients [PDF]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2015
We consider half-linear Euler type differential equations with general periodic coefficients. It is well-known that these equations are conditionally oscillatory, i.e., there exists a border value given by their coefficients which separates oscillatory ...

The cis-prenyltransferase protein family in Taraxacum koksaghyz. [PDF]

open access: yesPlant J
Significance Statement The novelty of this work lies in the comprehensive description of cis‐prenyl transferases in the rubber‐producing plant Taraxacum koksaghyz. This provides valuable insights for breeding and rational protein design in heterologous systems.

Comparison and oscillation theorems for singular Sturm-Liouville operators [PDF]

open access: yesOpuscula Mathematica, 2014
We prove analogues of the classical Sturm comparison and oscillation theorems for Sturm-Liouville operators on a finite interval with real-valued distributional potentials.

Mugharet el'Aliya: Affinities of an enigmatic north African Aterian maxillary fragment

open access: yesAmerican Journal of Biological Anthropology, Volume 180, Issue 2, Page 352-369, February 2023., 2023
Abstract Objectives This study uses a virtual framework to examine the left maxillary fragment of the juvenile fossil from Mugharet el'Aliya, Morocco, found in association with an Aterian lithic industry. Previously, this fossil had been ascribed to modern humans or the Neanderthal lineage based on its “archaic”/“Neanderthal‐like” features and apparent

Activity of AC electrokinetically immobilized horseradish peroxidase

open access: yesELECTROPHORESIS, Volume 43, Issue 18-19, Page 1920-1933, October 2022., 2022
Abstract Dielectrophoresis (DEP) is an AC electrokinetic effect mainly used to manipulate cells. Smaller particles, like virions, antibodies, enzymes, and even dye molecules can be immobilized by DEP as well. In principle, it was shown that enzymes are active after immobilization by DEP, but no quantification of the retained activity was reported so ...

Filling the gap. Human cranial remains from Gombore II (Melka Kunture, Ethiopia; ca. 850 ka) and the origin of Homo heidelbergensis [PDF]

open access: yes, 2016
African archaic humans dated to around 1,0 Ma share morphological affinities with Homo ergaster and appear distinct in cranio-dental morphology from those of the Middle Pleistocene that are referred to Homo heidelbergensis.

Bared‐teeth displays in bonobos (Pan paniscus): An assessment of the power asymmetry hypothesis

open access: yesAmerican Journal of Primatology, Volume 84, Issue 9, September 2022., 2022
The use of bared‐teeth (BT) displays in adult and immature bonobos at Apenheul Primate Park, the Netherlands. While adult bonobos produced the BT exclusively in the sexual context, regardless of dominance rank, immature bonobos produced the BT in a wider number of contexts. Abstract Facial expressions are key to navigating social group life.

Engineering asymmetric steady-state Einstein-Podolsky-Rosen steering in macroscopic hybrid systems [PDF]

open access: yes, 2019
Generation of quantum correlations between separate objects is of significance both in fundamental physics and in quantum networks. One important challenge is to create the directional "spooky action-at-a-distanc" effects that Schr\"{o}dinger called ...

Maya Pottery Production at Nakum, Guatemala, during the Protoclassic Period (100/50 BC – AD 300/350)

open access: yesArchaeometry, Volume 63, Issue 6, Page 1192-1215, December 2021., 2021
This study investigates the Protoclassic ceramic production at Nakum, Guatemala, using it as a proxy to explore the nature of the transition from the Preclassic to Classic period (100/50 BC – AD 300/350) in Central Maya lowlands. Petrographic analysis reveals that household specialisation existed in the local production of slipped serving and ...
