A path‐based two‐commodity flow model and a branch‐price‐and‐cut algorithm for the inventory routing problem with time windows

International Transactions in Operational Research, EarlyView.
Abstract We study an inventory routing problem with time windows (IRPTW). A single supplier serves a set of customers to fulfill their demand throughout a planning horizon. Each customer can be visited only within designated time windows, assuming each customer provides a single delivery time window valid for all periods.

The application of machine learning models to optimal TSP tour length estimation

International Transactions in Operational Research, EarlyView.
Abstract The traveling salesman problem (TSP) is a well‐known NP‐hard problem in combinatorial optimization, with numerous applications in logistics and elsewhere. This paper introduces a machine learning‐based approach to estimate the optimal tour length of the TSP, using linear regression, random forests (RF), and neural networks, including ...

Perceptivni distraktori utječu na reprezentacije vidnoga radnog pamćenja samo u ranim fazama obrade

Psychological Topics, 2022
Jedan je od glavnih zadataka vidnoga radnog pamćenja (VRP) zaštita pohranjenih sadržaja od nevažnih vidnih podražaja u okolini, tj. od distraktirajućih informacija. Iako velik broj istraživanja pokazuje negativan utjecaj distraktora na sadržaje u VRP-u,

Oral Health, Periodontitis, and Respiratory Diseases: Biological Pathways

Journal of Periodontal Research, EarlyView.
This narrative review aims to provide a comprehensive update on the potential mechanisms by which poor oral health and periodontitis impact lung health, focusing on pneumonia, COPD, and asthma. ABSTRACT Poor oral hygiene and periodontitis influence lung diseases such as pneumonia, chronic obstructive pulmonary disease (COPD), COVID‐19, and asthma.

Biologically‐Oriented Alveolar Ridge Preservation (BARP) in Intact and Compromised Extraction Sockets

Journal of Periodontal Research, EarlyView.
The Biologically‐oriented Alveolar Ridge Preservation (BARP) is an innovative technique characterized by the stratification of different biomaterials (collagen sponge and xenograft) at intact and compromised sockets. In both groups, the hard and soft tissue modification (bone width, bone height, tissue profile, and hard tissue composition) was limited.

Asymmetric information of variance risk premium in the Chinese market: upside and downside volatility spillovers

Management System Engineering
We investigate the degree of asymmetry in the variance risk premium (VRP) using SSE 50 ETF options in the Chinese market. Our approach decomposes the VRP into upside and downside components and quantifies the dynamic spillover asymmetry measure (SAM ...

Periodontitis Is Associated With Higher Blood Pressure and Pulse Wave Velocity in Late Adolescence: A Population‐Based Study

Oral Diseases, EarlyView.
ABSTRACT Objective We hypothesized that periodontal tissue disruption and vascular dysfunction may coexist in adolescence, indicating that early manifestations of vascular risk may already be detectable at this stage of the life course. Methods A population‐based sample of 2515 adolescents aged 18–19 years was obtained from the RPS Cohort and ...
