Hybrid genetic algorithm for undirected traveling salesman problems with profits

open access: yesNetworks, Volume 82, Issue 3, Page 189-221, October 2023., 2023
Abstract The orienteering problem (OP) and prize‐collecting traveling salesman problem (PCTSP) are two typical TSPs with profits, in which each vertex has a profit and the goal is to visit several vertices to optimize the collected profit and travel costs. The OP aims to collect the maximum profit without exceeding the given travel cost.

Extending exploratory diagnostic classification models: Inferring the effect of covariates

open access: yesBritish Journal of Mathematical and Statistical Psychology, Volume 76, Issue 2, Page 372-401, May 2023., 2023
Abstract Diagnostic models provide a statistical framework for designing formative assessments by classifying student knowledge profiles according to a collection of fine‐grained attributes. The context and ecosystem in which students learn may play an important role in skill mastery, and it is therefore important to develop methods for incorporating ...

Multisource Deep Transfer Learning Based on Balanced Distribution Adaptation

open access: yesComputational Intelligence and Neuroscience, Volume 2022, Issue 1, 2022., 2022
The current traditional unsupervised transfer learning assumes that the sample is collected from a single domain. From the aspect of practical application, the sample from a single‐source domain is often not enough. In most cases, we usually collect labeled data from multiple domains.

Numerical Model on the Dynamic Behavior of a Prototype Kaplan Turbine Runner

open access: yesMathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021
Experimental and numerical investigations of the modal behavior of a prototype Kaplan turbine runner in air have been conducted in this paper. The widely used roving accelerometer method was used in the experimental modal analysis. A systematic approach from a single blade model to the whole runner has been used in the simulation to get a thorough ...

Targeting cyclin B1 inhibits proliferation and sensitizes breast cancer cells to taxol [PDF]

open access: yes, 2008
Background Cyclin B1, the regulatory subunit of cyclin-dependent kinase 1 (Cdk1), is essential for the transition from G2 phase to mitosis. Cyclin B1 is very often found to be overexpressed in primary breast and cervical cancer cells as well as in cancer

Ostracod Genetic Variability in Response to Lake Level-Driven Salinity Dynamics in Nam Co, Central Tibetan Plateau, in the Past Two Millennia. [PDF]

open access: yesEcol Evol
Using sedimentary ancient DNA metabarcoding on a two‐millennia sediment core from Nam Co (Tibetan Plateau), the study reconstructs ostracod community shifts and genetic diversity in response to hydrological and climatic changes. Species richness peaked during moister intervals, while alternating dominance during the Medieval Climate Anomaly and Little ...

Nuclear translocation of Cyclin B1 marks the restriction point for terminal cell cycle exit in G2 phase [PDF]

open access: yes, 2014
Upon DNA damage, cell cycle progression is temporally blocked to avoid propagation of mutations. While transformed cells largely maintain the competence to recover from a cell cycle arrest, untransformed cells past the G1/S transition lose mitotic ...

Protective Effect of Simplicillium sp. Ethyl Acetate Extract against High Glucose‐Induced Oxidative Stress in HUVECs

open access: yesEvidence-Based Complementary and Alternative Medicine, Volume 2020, Issue 1, 2020., 2020
This study aimed at investigating the cytoprotective effect of an ethyl acetate extract of insect fungi against high glucose‐ (HG‐) induced oxidative damage in human umbilical vein endothelial cells (HUVECs). An insect fungus strain termed CH180672 (CH) was found for protecting HUVECs from HG‐induced damage.

Avicenna’s Interpretation of the Aristotelian Concept of Time

open access: yesFelsefe Arkivi, 2023
Aristotle characterized time as a number because he considered the earlier, later, and now being units associated with motion. In this context, the present study investigates time within the Peripatetic natural philosophy and the framework of numbered ...

Loving Gaze and Accurate Knowledge

open access: yesFelsefe Arkivi, 2022
Frequently, philosophers use examples to make their ideas clearer to readers. Later, commentators take these examples and go beyond the philosophers’ original intentions.
