Angle-Based Formation Stabilization And Maneuvers In Port-Hamiltonian Form With Bearing And Velocity Measurements, Ningbo Li, Pablo Borja, Arjan Van Der Schaft, Jacquelien M.A. Scherpen
Angle-Based Formation Stabilization And Maneuvers In Port-Hamiltonian Form With Bearing And Velocity Measurements, Ningbo Li, Pablo Borja, Arjan Van Der Schaft, Jacquelien M.A. Scherpen
School of Engineering, Computing and Mathematics
This paper proposes a port-Hamiltonian approach for angle-based formation stabilization and maneuvers using bearing and velocity measurements with an underlying triangulated Laman graph. The corresponding port-Hamiltonian controller is designed using virtual couplings on the errors of angle constraints in angle space. Then, the angle constraints and agent actuators are mapped by the constraint Jacobian, which can be applied to other formation constraints. In addition, to avoid unavailable distance terms in the control law, an estimator is designed based on port-Hamiltonian theory and the property that energy is coordinate-free for different sensor modalities using bearing and velocity measurements, which permits our …

The way humans relate to other animals is fundamentally shaped by whether we perceive ourselves as unique, with feelings and thoughts not shared by other animals. How beliefs about animals’ ability to feel and think develop across cultures remains largely unexplored. We asked children and adolescents (4–17 years, N = 1025) and adults (N = 190) from 33 urban and rural communities across 15 countries whether animals have thoughts or feelings (judgments of presence), and whether those thoughts or feelings are human-like (judgments of similarity). Bayesian analyses revealed that participants generally ascribed non-human animals the ability for thoughts and feelings. …

Association Of Arterial Partial Oxygen Pressure With Mortality In Critically Ill Patients With Sepsis: An Observational Prospective Cohort Study, Talal Ibrahim Mostafa Hagag, Salwa M.A. Dahesh
Journal of Medicine in Scientific Research
Background Up till now, the best oxygenation plan in sepsis is a moot point. Although both hypoxemia and hyperoxemia have been linked to negative outcomes, it is unclear whether the arterial oxygen tension (PaO₂) contributes to mortality on its own. The present study aimed to study the association between the arterial partial oxygen pressure and the mortality among critically ill patients with sepsis. Methods A prospective observational study was carried out, including 120 critically ill patients with sepsis. The patients were classified according to arterial partial oxygen pressure into two groups: the PaO₂ >80 mmHg group, which included 61 patients, …

Patients and Methods: Elective caesarean sections under spinal anesthesia were elective for 100 healthy …
Synergistic Removal Of Microplastic Fibres: Integrating Chitosan Coagulation In Hybrid Water Pre-Treatment Systems, Jayasuriya Arachchilage Nimesha Thathsarani
Synergistic Removal Of Microplastic Fibres: Integrating Chitosan Coagulation In Hybrid Water Pre-Treatment Systems, Jayasuriya Arachchilage Nimesha Thathsarani
Theses: Doctorates and Masters
Microplastic fibres (MPFs) are the most prevalent form of microplastics detected in the influents of water and wastewater treatment plants. Owing to their elongated shape and low density, MPFs frequently evade removal even during tertiary processes such as membrane filtration. Enhancing pretreatment, particularly through cost-effective coagulation-flocculation can reduce the treatment burden on downstream systems. However, conventional inorganic coagulants often necessitate high dosages and can leave residual ions, posing environmental concerns.
As a sustainable alternative, the use of environmentally friendly coagulants such as Chitosan has gained attention for MPF removal. While Chitosan exhibits favourable qualities, its practical application is hindered by …

Fibula Strut Allograft With Proximal Tibia Autograft For Treatment Of Humerus Nonunion: A Case Report And Review Of Oligotrophic Nonunion Management, Paul Wilson, Naomi Kelley, Samer Kakish
Western Journal of Orthopaedics
Due to their high incidence and frequent need for reoperation, nonunions of the humerus present a significant challenge in orthopaedics. Using fibular struts to treat nonunions have demonstrated excellent results. While fibular autografts provide both biologic and structural benefit, high donor site morbidity must be considered. Although their application in midshaft humeral nonunions remains limited, fibular allografts avoid donor site morbidity. Enhancing fibular strut allografts with biological components offers a promising strategy for treating fractures that have failed prior revisions. This case study presents a 36-year-old woman with an aseptic oligotrophic midshaft humeral nonunion who had an unsuccessful revision surgery. …

21st Century Perspective On The Changing Pattern Of Nerve Injuries From Gunshot Wounds In The U.S., Thomas A. Decoster
21st Century Perspective On The Changing Pattern Of Nerve Injuries From Gunshot Wounds In The U.S., Thomas A. Decoster
Western Journal of Orthopaedics
Gunshot wounds (GSWs) with nerve injuries in the 21st century differ significantly from those reported in the 20th century. The vast majority are now low-velocity civilian injuries, in contrast to high-velocity military injuries previously reported. The rate of nerve injury in civilian GSWs is approximately 5%, compared with the 30% reported in military cohorts. However, the most common pattern of nerve injury in the current civilian population is neurotmesis and partial neurotmesis, in contrast to the majority axonotmesis of the military cohorts. In the 20th century, treatment generally consisted of watchful waiting for signs of spontaneous recovery over three months …

Peripheral Nerve Repair And Reconstruction: Current Techniques, Adjuncts, And Emerging Therapies, Niklaus Skipp, Lana Dokic, Christina Wassef, Jazzlyn Gonzalez, Ana Love, Heather Mercer, Deana Mercer
Western Journal of Orthopaedics
Peripheral nerve injuries require reconstruction when direct, tension-free repair is not possible. A range of reconstructive strategies are used to restore continuity and promote axonal regeneration, including graft-based reconstruction, nerve transfers, conduit-based repair, supercharged end-to-side augmentation, and emerging regenerative therapies. Autologous interfascicular nerve grafts and vascularized grafts remain established techniques, whereas processed nerve allografts provide a donor-sparing alternative. Nerve transfers are increasingly used for proximal injuries with long regeneration distances, and conduits are an option for gaps shorter than 5 mm. Nerve-wrapping techniques are used to reduce perineural scarring and preserve gliding in complex or revision cases. Emerging adjunctive therapies, …

Western Journal of Orthopaedics
High-energy proximal tibia fractures present significant challenges for orthopaedic surgeons, with well-recognized risks including malreduction and nonunion. Although double plating through two mini-open parallel incisions is an established technique for selected patients, nonuion can still occur. One potential contributing factor is entrapment of the popliteus muscle within the distal spike of the posteromedial plateau fragment. This report uses illustrative cases to demonstrate how to identify, address, and prevent this complication. Strategies for managing delayed cases that progress to nonunion are also discussed
Exploring The Interaction Between Cranial Nerves V And Vii In Chronic Eyelid Myokymia: A Case Report, Karina Miramontes, Adam Walsh, Tomas Tafoya
Exploring The Interaction Between Cranial Nerves V And Vii In Chronic Eyelid Myokymia: A Case Report, Karina Miramontes, Adam Walsh, Tomas Tafoya
Western Journal of Orthopaedics
Eyelid myokymia involves involuntary contractions of the orbicularis oculi muscle and is commonly associated with stress, fatigue, and craniocervical factors. Emerging evidence suggests that altered trigeminocervical interactions and craniomandibular muscle tension may contribute to symptom persistence; however, the condition remains underrecognized in physical therapy. This report describes a 65-year-old woman with chronic benign eyelid myokymia and cervical pain who completed 12 physical therapy sessions that included suboccipital functional dry needling, temporomandibular soft-tissue mobilization (STM), and cervical stabilization exercises. A reduction in eyelid myokymia was first observed at the fifth visit, coinciding with the initiation of temporomandibular STM. These findings suggest …

Massive Upper Extremity Neurofibroma Treated With Limb-Sparing Debulking: A Case Report, Danielle Cummings, Tomas Holy, Nathan Morrell
Western Journal of Orthopaedics
Surgical management of neurofibromas in Neurofibromatosis type 1 (Von Recklinghausen’s disease), can be challenging because tumor size, location, hypervascularity, and tissue friability pose the risk for significant intraoperative and postoperative blood loss. Despite these risks, surgery is often necessary because of functional losses or cosmetic concerns. The authors present a 31-year-old woman with a massive neurofibroma on her right distal forearm, wrist, and hand, who ultimately underwent surgical resection because of functional impairment of her hand. She required postoperative hospitalization and blood transfusion for management of acute blood loss anemia. Because of concerns regarding blood loss and surgical morbidity, the …

Median Nerve Intraneural Hematoma As An Intraoperative Finding During Carpal Tunnel Release: A Case Report, Ana Silva, Gil Gonrtre, Nikalus Skipp, Ana Love, Deana Mercer
Western Journal of Orthopaedics
Carpal tunnel syndrome (CTS) is the most common compressive neuropathy and typically progresses slowly. Intraoperatively, flexor tenosynovitis, nerve edema, or hourglass deformity may be observed. In rare cases, acute compression symptoms occur due to mass effect on the nerve. Intraneural hematoma of the median nerve is uncommon and has been reported primarily in acute CTS cases associated with trauma. This report describes an 87-year-old patient with a history of mild CTS who underwent carpal tunnel release due to worsening symptoms. After the initial incision, a thickened flexor retinaculum, an hourglass deformity of the median nerve, and an intraneural hematoma were …

Proximal Iliotibial Band Rupture In A 74-Year-Old High-Level, Female Athlete: A Case Report, Jeremiah M. Langsfeld, Joseph Esquibel, Dustin L. Richter
Western Journal of Orthopaedics
A 74-year-old female endurance athlete presented with progressive pain over the left proximal and lateral hip distal to the iliac crest. Symptoms developed over three weeks, impairing weightbearing. Magnetic resonance imaging demonstrated a high-grade tear of the proximal iliotibial band at its iliac crest insertion. The patient was treated nonoperatively and returned to high-level, asymptomatic competition three months after symptom onset. This case offers a nonoperative approach to the rare presentation of a proximal iliotibial band rupture.

Arthroscopic Treatment Of Extensive Synovial Chondromatosis Of The Knee: A Case Report, Gaurav Singh, Bhavna Singh, Rebecca Peebles, Justin Bartley
Western Journal of Orthopaedics
Synovial chondromatosis (SC) is a rare, benign monoarticular disorder characterized by intra-articular cartilaginous loose bodies resulting from synovial metaplasia, most commonly affecting the knee. The authors present the case of a 44-year-old man with progressive, debilitating left knee pain, mechanical symptoms, and functional limitations unresponsive to conservative treatment. Radiographs were unremarkable, but magnetic resonance imaging (MRI) demonstrated multifocal noncalcified intra-articular bodies consistent with SC. The patient underwent arthroscopic debridement of the knee with limited synovectomy. Intraoperative findings included innumerable intra-articular cartilaginous loose bodies throughout the knee, synovial proliferation, and grade II chondromalacia. At three months postoperatively, the patient had regained …
