Stability Analysis of Autonomous Microgrid Operated at Constant-Frequency with the Consideration of Reactive Power Balanceby
Abstract
Large-scale autonomous microgrids have potential application values as they can increase renewable energy penetration level without compromising the stability of the existing large power systems. Before their widespread implementation, critical issues like stability analysis etc need to be solved. This paper analyses the stability in an autonomous microgrid operated at constant frequency with the consideration of reactive power balance. Difference equations of reactive power for the grid-forming generator are const [...] 1086 6092 |

Nonlinear Optimal Control for a PMLSG-VSC Wave Energy Conversion Unitby
Abstract
This article aims to treat the nonlinear control problem for the complex dynamics of a wave energy unit (WEC) that consists of a Permanent Magnet Linear Synchronous Generator (PMLSG) and a Voltage Source Converter (VSC). The article has developed a globally stable nonlinear optimal control method for this wave power generation unit. The new method avoids complicated state-space model transformations and minimizes the energy dispersion by the control loop. A novel nonlinear optimal control method is proposed for the [...] 946 6086 |
Non-Renal Factors Associated with Simultaneous Liver-Kidney Transplant in Patients with End-Stage Liver Disease and Stage 3-5 Chronic Kidney Disease Not Requiring DialysisAbstract
We aimed to identify the non-renal risk factors for simultaneous liver-kidney transplantation (SLKT) vs. liver transplantation alone (LTA) in end-stage liver disease (ESLD) patients with estimated glomerular filtration rate (eGFR) <60 ml/min, not on dialysis. Using organ procurement and transplantation network data, we studied adult ESLD patients who received deceased-donor SLKT or LTA in July 2002-Mar 2016 with a 4-point modification of renal disease (MDRD) equation-estimated glomerular filtration rate (eGFR) s [...] 776 6079 |
Modified Organized Systems by Incorporation of Carbon Allotropes and Derivatives for Electron Shuttle, ET, FRET, MEF, and Quantum Biology CouplingAbstract
This communication was brief to show how high conjugated carbon-based structures and carbon allotropes could participate as electron shuttles, semiconductors, quantum emitters, and Optoelectronic processors within confined nanostructured organized systems. In particular, it was focused on nanoassemblies such as vesicles, micelles, and lipidic nanoparticles and incorporated insights from other types of nanomaterials that could afford to develop new organized systems. In these cases, the term organized system was use [...] 949 6066 |
Exploring the Regenerative Potential of Stem Cells for Treating Eye Diseases: A Review of the New FindingsAbstract
The escalating prevalence of vision loss due to eye diseases has instigated a quest for innovative therapies, given that conventional approaches often fall short in repairing and regenerating damaged eye tissues, particularly the retina. Stem cell-based interventions have emerged as a promising avenue, with numerous studies in animal models and human trials exploring their potential to enhance visual acuity. Beyond addressing conditions like age-related macular degeneration (AMD) and diabetic retinopathy (DR), stem [...] 1078 6059 |
A Child Carrying a Large Deletion in the 10p.15.3-p12.31 RegionAbstract
Partial deletion of 10p is a rare disorder. Common features of this disorder include intellectual disability, developmental delay, dysmorphic features, hypoparathyroidism, deafness, and renal anomalies, but the phenotypes can vary between patients. We report an infant girl presented with global developmental delay, distinctive facial features with cleft lip, congenital exotropia, laryngomalacia, atrial septal defect, and sensorineural hearing loss. 46, XX, del (10p→ter) was observed on the G-banded analysis. A chro [...] 749 6057 |
Chemical Neuroscience of Heterocyclic N-Amines: Implications for Pain Management, Mental Health, and Opioid Withdrawalby
Abstract
This study reviews the biochemical mechanisms and clinical implications of N-heterocyclic amine drugs, particularly in the context of pain management, mental health, and opioid withdrawal. It highlights the structural diversity and receptor binding capabilities of these compounds, which enable them to target the nervous system and cross the blood-brain barrier effectively. The article discusses the role of opioids in pain relief, detailing their agonistic effects on opioid receptors and the subsequent risk of addic [...] 917 6050 |
The Indigo Project: Participatory Action Research with Gender and Sexual Minority Survivors of Elder AbuseAbstract
Though research suggests that older adults belonging to gender and sexual minorities (GSM) are at greater risk of abuse and neglect, more needs to be done to investigate this situation, provide solid data, offer support to survivors and better inform those providing services. This article reports on a participatory action research project in which nine older adults with lived experience of abuse were interviewed, as were the seniors’ programmer from our community partner organization and a trauma counsellor who sup [...] 877 6043 |
Management of Steatosis in Living Donors: Where Do We Stand?Abstract
With the progressive rise in rates of liver transplantation, stagnant donor pool, and social factors, living donor liver transplantation (LDLT) forms the majority of liver transplantations performed in Asian countries. As the global prevalence of metabolic-associated fatty liver disease (MAFLD) is increasing, around 17-25% of all the prospective donors turn out to be steatotic at the time of evaluation and, as such, rejected for donor hepatectomy, thereby considerably reducing the living donor pool. Steatotic graft [...] 858 6043 |
