Fault Tolerant Adaptive Control Under Actuator Saturation For Robot Manipulators, D. J. López-Araujo, N. Alvarez-Jarquin, P. Borja, A. T. Becker

School of Engineering, Computing and Mathematics

In practice, actuators inherently have natural limitations that are often overlooked by theoretical control strategies, such as bounded output and discrepancies between calculated and actual responses. Consequently, reliable control techniques must be employed to ensure safe and dependable operation. We propose an adaptive control law for global regulation in the case of partial loss of effectiveness due to input faults. The proposed control strategy maintains the system at the desired configuration while accounting for the physical limitations of the actuators. Additionally, it is suitable for dealing with unknown parameters in the vector of gravitational forces, making it robust to these …

Drawing on academic and commercial developments, the discussion highlights the growing burden on users who must authenticate across …

Rapid Electrochemical Biosensor With Enhanced Accuracy And Repeatability Using Pyrene Nhs Ester Modified 3d Graphene Electrodes, S. Nazir, D. Jenkins, G. Pan

School of Engineering, Computing and Mathematics

A consistent and reproducible chemical modification of the transducer interface is essential to ensure effectiveimmobilization of bioreceptors, thereby improving the sensitivity and reproducibility of biosensors. Althoughnotable progress has been made in fabricating graphene-based biosensors, the effects of surface biofunctionalization on sensing performance remain not fully understood. This study shows that combining threedimensional (3D) graphene foam electrodes with a straightforward, single-step surface biofunctionalizationmethod is key to enhancing the performance of graphene-based biosensors. Specifically, it presents a single-stepapproach to functionalize the 3D graphene foam (Gii-Sens) with 1-pyrenebutyric acid N-hydroxysuccinimideester (Pyrene-NHS ester). Electrochemical techniques, including cyclic voltammetry (CV) and differential pulsevoltammetry (DPV), confirmed …

School of Engineering, Computing and Mathematics

OBJECTIVES: Peri-implantitis compromises soft and hard tissues around dental implants, often leading to implant failure. Antibacterial nanocoatings offer a promising infection control strategy, but maintaining biocompatibility is essential. This study investigated, through a range of assays and analytical techniques, the biocompatibility of antimicrobial silver and hydroxyapatite (HA) nanocoatings applied to titanium implants with human gingival fibroblasts (HGFs).

METHODS: Silver and hydroxyapatite nanocoatings were applied to the surface of titanium alloy specimens using electroplating, deposition and sintering techniques. The biocompatibility of the nanocoatings with HGFs was assessed by measuring cell metabolic activity (alamarBlue), lactate dehydrogenase (LDH) release, collagen production (Sircol assay), …

Heat Transfer From A Partially Buried Circular Cylinder In Oscillatory Flow, H. Thomas, R. Stuhlmeier, A. G.L. Borthwick, S. Michele

School of Engineering, Computing and Mathematics

With the growing abundance of man-made cylindrical structures located on or close to the seabed, it is important to be able to assess their potential environmental impact. Herein, a model is presented of the viscous-thermal boundary layer in the vicinity of a circular cylinder resting on, or partially buried in, an otherwise flat seabed. To model the influence of wave-induced motions near such a cylinder, we assume oscillatory flow in which the water particle displacements are small with respect to the cylinder radius. A perturbation expansion is utilised to derive solutions of the boundary layer equations, leading to analytical solutions …

Diagnosing Long-Term Divergence In Build Back Better Outcomes In Low- And Lower-Middle-Income Communities, E. A. Opabola, M. Baiguera, A. Raby, T. Rossetto, A. Pomonis, E. Meilianda, Y. Idris, S. Nurdin, K. Adams, D. J. Mcgovern, N. Acikgoz, H. Mistry, F. Marafini

School of Engineering, Computing and Mathematics

Low-income communities in disaster-prone regions face persistent challenges in translating post-disaster recovery investments into sustained resilience, as they navigate trade-offs among engineering objectives, policy constraints, and evolving socio-economic needs. Despite the widespread adoption of Build Back Better (BBB) principles, evidence on the long-term sustainability of outcomes remains limited, particularly in low- and lower-middle-income contexts. This study examines the sustainability of BBB outcomes in two Indonesian case studies: Banda Aceh (approximately 18 years after the 2004 Indian Ocean tsunami) and Central Sulawesi (approximately 4 years after the 2018 earthquake, liquefaction, and tsunami). Drawing on structured housing assessments, household surveys, semi-structured interviews, …

Land, Genocide, And Kintsugi In Namibia, Mark A. Drumbl, Shannon Fyfe

Scholarly Articles

The first German missionaries arrived in Namibia in the 1820s. German rule over Namibia officially began under Otto von Bismarck in 1884. Following a January 1904 uprising led by Herero chief Samuel Maharero against colonial rule, German officials ordered the extirpation of the Herero and Nama peoples. On 4 October 1904, German military commander General Lothar von Trotha issued a chilling extermination order (Vernichtungsbefehl) to his troops: "Every Herero, with or without a gun, with or without cattle, will be shot. I will no longer accept women and children, I will drive them back to their people or …

Dysfunctional Leadership As A Dynamic And Relational Process, Rory E. Kuhn, S. Burak Ozkum

Faculty Publications – Psychology

First paragraph in lieu of abstract:

The focal article by Ducheyne and De Fruyt (2026) calls for a clear conceptual distinction between toxic and incompetent leadership, proposing that these categories can guide research and practice by reducing ambiguity. Although we agree that this differentiation offers useful conceptual clarity, we contend that it becomes unstable in its application. Dysfunctional leadership unfolds through both temporal fluctuation in leader behavior and relational variation in follower appraisal. These intertwined processes suggest that the same leader may appear toxic in one moment and merely incompetent in another, depending on shifting behavioral cues and the relational …

Steroid Hormone Metabolites And Mammographic Breast Density In Premenopausal Women, Ghazaleh Pourali, Kayode A Matthew, Myung Sik Jeon, Chongliang Luo, Gary J Patti, Jingqin Luo, Adetunji T Toriola

2020-Current year OA Pubs

BACKGROUND: Steroid hormones influence breast morphology and cellular proliferation and are associated with breast carcinogenesis. However, their associations with mammographic breast density (MBD) are less studied, particularly in premenopausal women. We, therefore, investigated the associations of steroid hormone metabolites with MBD in premenopausal women.

METHODS: Our study included 700 premenopausal women scheduled for screening mammograms. We analyzed 54 steroid hormone metabolites (Metabolon®) and assessed volumetric measures of MBD including volumetric percent density (VPD), dense volume (DV), and non-dense volume (NDV) using Volpara. We investigated associations using linear regression modeling to estimate the covariate-adjusted means of VPD, NDV, and DV, corresponding …

Acute Correction Of Acquired Genu Valgum Secondary To Post-Traumatic Growth Arrest At The Time Of Distal Femur Fracture., Josiah Wolf, Nicholas Pelz, Adam Mansour, Christopher Iobst, Allen Kadado

Surgery Articles

A 14-year-old male patient sustained a distal femur fracture after a ground-level fall. His history was notable for severe acquired genu valgum secondary to a childhood lawnmower accident, which had required multiple limb salvage procedures including a Syme amputation and soft-tissue skin grafting. Acute correction of the limb deformity was performed concurrently with fracture fixation using a retrograde intramedullary nail and poller blocking screws. Retrograde intramedullary nailing represents a viable treatment option for simultaneous acute correction of acquired genu valgum and stabilization of distal femur fractures.

Anti-Zionism, Antisemitism, Antidiscrimination, Zalman Rothschild

Articles

This Article uses recent anti-Zionism cases as a case study in hostile environment causation. It briefly surveys the approaches to the causation element that courts have taken in other contexts and then examines the anti-Zionism decisions in detail. It finds that courts in these cases have consistently converged on the narrowest variant of the motive-based approach, treating proof of animus—subjective hostility toward Jews—as the operative route to causation. That approach has its attractions. It preserves breathing space for political speech and resists the claim that opposition to Zionism is necessarily hostility toward Jews. But it is not the only approach …

Frontline Aspiration Versus Stent Retriever Thrombectomy For M2 Occlusions: Insights From The Star Registry, Michael Gaub, Joshua Osbun, Et Al.

2020-Current year OA Pubs

BACKGROUND: Recent trials have furthered uncertainty regarding the endovascular benefit for medium vessel occlusions (MeVO). Stent retrievers (SR) were employed in the first attempt in most interventional arm participants. We sought to compare outcomes in acute MCA M2 occlusions between frontline aspiration and SR, and to delineate procedural and anatomical covariates associated with differential treatment effect.

METHODS: Retrospective analysis of a multicenter stroke thrombectomy cohort identified cases of MT for M2 occlusions. Unmatched and propensity score-matched (PSM) cohorts were generated comparing frontline aspiration to standalone and combined SR. The primary outcome was functional independence (mRS 0-2) at 90 days. Recanalization, …

2020-Current year OA Pubs

BACKGROUND & AIMS: Patients with advanced hepatocellular carcinoma (HCC) generally experience poor outcomes despite current therapies, necessitating the development of alternative treatments. ADP-A2AFP is an investigational autologous T-cell therapy with an affinity-enhanced T-cell receptor (TCR) targeting alpha-fetoprotein (AFP).

METHODS: We describe a phase I, open-label, first-in-human clinical trial of ADP-A2AFP (NCT03132792) in human leukocyte antigen-eligible participants with AFP-expressing HCC (or other tumor) not amenable to transplant/resection who progressed on, were intolerant to, or refused prior systemic therapy. Participants received lymphodepletion chemotherapy (cyclophosphamide 500 mg/m

RESULTS: Twenty-one participants, 20 with advanced HCC and one with gastric hepatoid carcinoma received ≥1 ADP-A2AFP …

Coordinated Regulation Of Capping Protein By Carmil And V-1/Myotrophin, John A Hammer, John A Cooper

2020-Current year OA Pubs

Capping Protein (CP) plays a central role in controlling actin filament dynamics in almost all eukaryotic cell types by virtue of its ability to block monomer addition and loss at the barbed end of the actin filament. Like other proteins that control actin assembly, CP is subject to regulation. Here we focus on two direct regulators of CP-CARMIL and V-1/Myotrophin. Specifically, we review recent biochemical, structural, imaging, and cell biological data that argue these two proteins cooperate to create a regulatory cycle for CP that controls its availability, activity, and site of action in the cell. Finally, we discuss unresolved …

Mutations In Hsp40 Co-Chaperone Change The Canonical Interdomain Interactions Stimulating Lgmdd1 Myopathy, Ankan K Bhadra, Geetika Aggarwal, Anshuman Jaysingh, Daniel Chen, Jil Daw, Conrad C Weihl, Heather L True

2020-Current year OA Pubs

Limb-girdle muscular dystrophy D1 (LGMDD1) is a rare, dominantly inherited neuromuscular protein-misfolding chaperonopathy caused by mutations in the Hsp40 co-chaperone DNAJB6, primarily in the glycine-phenylalanine (GF) or J-domains. Currently, no treatments are available, and a challenge in understanding the disease is identifying a specific client protein for DNAJB6 in skeletal muscle. DNAJB6 has homology to the yeast DNAJ family member, Sis1. Our previous research indicated that LGMDD1 GF domain mutants in Sis1 exhibit substrate-specific effects, influenced by Hsp70 activity. Herein, we employed functional assays along with advanced molecular simulation studies to understand the regulatory interdomain interactions in disease-causing mutants of …
