Fixed-Switching Frequency Finite-State Model Predictive Thrust and Primary Flux Linkage Control for LIM

Received: 14 February 2023;  Published: 09 May 2023;  doi: 10.21926/jept.2302017

Abstract

The special design of linear induction machines (LIMs) leads to adverse effects caused by the longitudinal and end effects. These effects make the thrust control of the LIMs most attractive because its value decreases sharply with the speed increase. Thus, finite-state model predictive control (FS-MPC) is developed to increase the performance of the LIMs. However, the variable switching frequency is the main drawback of this control. Consequently, the main objectives of this paper are to propose FS-MPC with a const [...]

Carbon Taxation as An Instrument to Promote Wildfire Prevention and Avoid Biodiversity Loss in Portugal: An Order of Magnitude Analysis

Received: 09 September 2022;  Published: 15 December 2022;  doi: 10.21926/aeer.2204051

Abstract

Climate change is one of the main challenges of the current century. Emissions taxes are one of the proposed ways to help in addressing this issue. In this sense, Portugal has introduced an Addition Tax on Carbon Emissions through Law N. 82-D/2014. One of the most notorious impacts of climate change in the country is the wildfires increasing in frequency and intensity. Forests provide various ecosystem services not valued by traditional markets, such as carbon sequestration. Recently, Portugal has created new envir [...]

Coronavirus Disease 2019 (COVID-19) Pandemic’s Effect on Child and Adolescent Mental Health: Analysis of Pediatric Intensive Care Unit and Consultation-Liaison Psychiatry Service

Received: 03 October 2022;  Published: 02 March 2023;  doi: 10.21926/obm.neurobiol.2301159

Abstract

The Coronavirus Disease (COVID-19) pandemic has contributed to a co-occurring psychiatric epidemic. Children and adolescents have been particularly impacted, with disruptions in continuity of learning and healthcare. Psychological stressors such as fear of infection, boredom, decreased socialization, supply shortages, and incomplete information have contributed to low mood, irritability, insomnia, and emotional exhaustion. Our study contributes to this research by quantifying the devastating psychiatric toll that t [...]

An Estimate of Possible Impacts of Superoxide Chemistry on Seawater pH: A Mapping Exercise

Received: 05 September 2019;  Published: 21 January 2020;  doi: 10.21926/obm.acr.2001004

Abstract

Superoxide, produced photochemically as well as microbially, is an important reactant present in seawater and a major source of hydrogen peroxide. Superoxide decay may occur through catalyzed or uncatalyzed dismutation forming H2O2 and O2, through oxidation to O2, or through reduction into H2O2. Under definite circumstances, the redox processes that are different from dismutation could produce or consume H+, thereby altering the pH of seawater. In order to alter the pH, these processes have to involve, together wit [...]

Physiological Response of a Natural Central Incisor Tooth to Various Loading Conditions: A 3D Finite Element Study

Received: 05 May 2022;  Published: 24 April 2023;  doi: 10.21926/rpm.2302017

Abstract

This study evaluates the influence of different loading angles and the area of loading on the ensuing stress distribution and the physical response of a natural central incisor tooth, using a 3D finite element analysis. The CAD model of the incisor tooth assembly (including enamel, dentin, periodontal ligament, pulp, gingiva and jaw bone) was subject to an external (chewing) load of 100 N, over four different areas and at four different angles along the vertical. It was observed that the tooth experiences high von- [...]

The Biomolecular Basis of Gut Microbiome on Neurological Diseases

Received: 23 February 2024;  Published: 16 July 2024;  doi: 10.21926/obm.neurobiol.2403232

Abstract

The human gastrointestinal (GI) tract harbors many microorganisms, including viruses, protozoa, archaea, fungi, and bacteria. Altogether, these microbes constitute what we know as the gut microbiome (GM). These commensal communities have important implications for human health. They influence physiological processes through different mechanisms, including synthesizing neurotransmitters, regulating enzymatic pathways, and releasing molecules responsible for different signal pathways. The interaction between GM and b [...]

A Systematic Literature Review on the Application of Explainable AI Approaches in the Assessment of Autism Spectrum Disorder

Received: 16 January 2025;  Published: 15 August 2025;  doi: 10.21926/obm.neurobiol.2503298

Abstract

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder associated with significant heterogeneity in symptoms and comorbid conditions. Studies have shown the value of early and accurate diagnosis in mitigating the associated social and behavioral challenges. Recently, studies have demonstrated the potential of machine learning (ML) models in identifying ASD patterns from neuroimaging, genetic, and behavioral data. However, the limited interpretability of these models poses a barrier to their clinical adopti [...]

The Daclatasvir/Asunaprevir/Beclabuvir Combination Therapy for Chronic Hepatitis C Patients Experiencing Failure of IFN-Free DAA-Based Therapies

Received: 29 September 2019;  Published: 17 December 2019;  doi: 10.21926/obm.hg.1904041

Abstract

Background: Daclatasvir/asunaprevir/beclabuvir (DCV/ASV/BCV) combination therapy had been available for the treatment of chronic hepatitis C patients with genotype 1 (CHG1) in Japan. Our aim was to report the efficacy and safety of DCV/ASV/BCV in patients experiencing treatment failure with interferon (IFN)-free direct-acting antiviral agent (DAA)-based therapies, which have not been fully evaluated. Methods: We evaluated the efficacy and safety of 12-week DCV/ASV/BCV combination therapy for CHG1 patients experien [...]

Integration between Geriatric Oncology and Palliative Care: A Single Center Experience for Hospitalized Older Patients with Cancer

Received: 26 October 2022;  Published: 27 March 2023;  doi: 10.21926/obm.geriatr.2301230

Abstract

Comprehensive Geriatric Assessment (CGA) is utilized to plan social and health care of the elderly and to complete the diagnostic-therapeutic choice of oncologist also considering early integration with palliative care. Cancer patients (pts) hospitalized aged ≥70 years were screened by the G8 questionnaire to define if necessary CGA. CGA identified: fit, unfit and frail pts. We screened 95 pts by G8 and 93 (98%) were at risk. Pts at risk, evaluated by CGA resulted: 3 fit, 45 unfit and 45 frail. 3 fit pts received s [...]
