On the n-fold symmetric product suspensions of a continuum

, 2010
In 1979 Sam B. Nadler, Jr. defined the hyperspace suspension of a continuum. We define the n-fold symmetric product suspensions of a continuum using n-fold symmetric products. We study some properties of this hyperspace: unicoherence, local connectedness,

About $wcs$-covers and $wcs^*$-networks on the Vietoris hyperspace $\mathcal F(X)$

, 2023
summary:We study some generalized metric properties on the hyperspace $\mathcal F(X)$ of finite subsets of a space $X$ endowed with the Vietoris topology. We prove that $X$ has a point-star network consisting of (countable) $wcs$-covers if and only if so

A Machine Learning Framework for Detecting and Preventing Cyber‐Attacks in Industrial Cyber‐Physical Systems

Engineering Reports, Volume 8, Issue 1, January 2026.
Proposed cyber physical system security framework. ABSTRACT The increasing adoption of cyber‐physical systems (CPS) in Industry 4.0 has heightened vulnerability to cyber threats. This study proposes a machine learning–based intrusion detection framework, DBID‐Net, to effectively identify and prevent attacks in CPS environments. The framework integrates

Licochalcone A as Novel Multitarget Inhibitors via AChE, BuChE, and Synapsin III for Therapeutic Intervention Against Alzheimer’s Disease: Computer‐Aided Drug Design

Journal of Chemistry, Volume 2026, Issue 1, 2026.
Alzheimer’s disease (AD) is characterized by key pathological features, including cholinergic dysfunction, amyloid‐beta (Aβ) aggregation, and disrupted synaptic transmission, positioning proteins such as acetylcholinesterase (AChE), butyrylcholinesterase (BuChE), and Synapsin III as critical targets for therapeutic strategies.

Addressing Sustainability Challenges in Peptide Synthesis with Flow Chemistry and Machine Learning

Chemistry – A European Journal, Volume 31, Issue 72, December 23, 2025.
A synthetic protocol for polypeptides 6–58 residue long, using recyclable greener solvent mixture (Anisole/DMSO) was developed and compared to traditional SPPS methods and to state‐of‐the‐art synthesizers. Abstract The high cost and the large amount of toxic waste generated during peptide production overshadow the current technology, requiring the ...

The polyploid continuum and the landscape of polyploid genomic variation

American Journal of Botany, Volume 112, Issue 11, November 2025.
Abstract Polyploid research has traditionally distinguished between autopolyploids and allopolyploids on the basis of evolutionary origins, modes of inheritance, or chromosomal pairing behavior during meiosis. It has long been recognized, however, that a binary classification does not accurately reflect the complexity and diversity inherent to ...

The hyperspace graph of connected subgraphs

, 2005
Given a connected graph G, the hyperspace graph of connected subgraphs C (G) is defined. The graph C (G) is such that every vertex represents a connected subgraph of G. It is shown that every connected graph G has a unique graph C (G).

Determine the Elemental Composition of Minerals From Complex Solid‐Solution Series by Raman Spectroscopy: Implications for Mars Exploration Missions

Journal of Raman Spectroscopy, Volume 56, Issue 11, Page 1404-1417, November 2025.
This study presents a hierarchical Raman‐based classification model for determining the elemental composition of garnets within complex solid‐solution systems. The workflow combines spectral preprocessing, dimensionality reduction, and two‐level classification: first distinguishing between pyralspite and ugrandite groups, and then classifying ...
