Note on the shape-preservation of a new class of Kantorovich-type operators via divided differences
Shape-preserving approximation is a significant approximation method that has many application areas, such as computer-based geometric design, image processing, geodesy, chemistry, and robotics.

Uniformly Continuous Generalized Sliding Mode Control
This paper explores a general class of singular kernels with the objective of designing new families of uniformly continuous sliding mode controllers. The proposed controller results from filtering a discontinuous switching function by means of a Sonine ...

Modelling stem cell differentiation related processes—A practical overview for biologists
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Order-Preserving Symmetric Encryption [PDF]
We initiate the cryptographic study of order-preserving symmetric encryption (OPE), a primitive suggested in the database community by Agrawal et al.~(SIGMOD \u2704) for allowing efficient range queries on encrypted data.

Transfer Function Synthesis without Quantifier Elimination [PDF]
Recently it has been shown how transfer functions for linear template constraints can be derived for bit-vector programs by operating over propositional Boolean formulae. The drawback of this method is that it relies on existential quantifier elimination,

Design and analysis strategies for robust microbiome ageing research
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Let 𝒜 be the class of analytic functions in the open unit disk . We define Θα,β:𝒜→𝒜 by (Θα,βf)(z):=Γ(2−α)zαDzα(Γ(2−β)zβDzβf(z)),(α,β≠2,3,4…), where Dzγf is the fractional derivative of f of order γ. If α,β∈[0,1], then a function f

Reconstructing enzyme evolution by protein engineering
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

The relevance of preserving the Nizhniv bridge as a monument of bridgebuilding
Introduction. This article reveals the historical and architectural value of bridges over 100 years old using the example of a bridge in the village of Nyzhniv, Ivano-Frankivsk region. The article will provide a general description of the structure, data

Classification of Hyperspectral Images Based on Supervised Sparse Embedded Preserving Projection
Dimensionality reduction is an important research area for hyperspectral remote sensing images due to the redundancy of spectral information. Sparsity preserving projection (SPP) is a dimensionality reduction (DR) algorithm based on the l1-graph, which ...
