The extraordinary mechanical flexibility, high electrical conductivity, and nanoscale instability of freestanding graphene make it an excellent candidate for vibration energy harvesting. When freestanding graphene is stretched taut and subject to external forces, it will vibrate like a drum head. Its vibrations occur at a fundamental frequency along with higher-order harmonics. Alternatively, when freestanding graphene is compressed, it will arch slightly out of the plane or buckle under the load. Remaining flat under compression would be energetically too costly compared to simple bond rotations. Buckling up or down, also known as ripple formation, naturally creates a bistable situation. When the …

Kerr-cat qubits are bosonic qubits offering autonomous bit-flip protection, traditionally studied using driven superconducting nonlinear asymmetric inductive element (SNAIL) oscillators. Here, we theoretically explore an alternative circuit for Kerr-cat qubits based on symmetrically threaded superconducting quantum interference devices (SQUIDs). The symmetrically threaded SQUID (STS) architecture employs a simplified flux-pumped design that suppresses two-photon dissipation, a dominant loss mechanism in high-Kerr regimes, by engineering the drive Hamiltonian’s flux operator to generate only even-order harmonics. By fulfilling two critical criteria for practical Kerr-cat qubit operation, the STS emerges as an ideal platform: (1) a static Hamiltonian with diluted Kerr nonlinearity (achieved via …

Faculty, Staff and Student Publications

Background: Alzheimer's disease (AD) may cause significant psychosocial distress not only in the patient but also their partner. However, long-term risks of major depression in partners of AD patients are largely unknown.

Methods: A national cohort study was conducted of all 145 289 partners of people diagnosed with all-cause dementia, including 57 113 partners of people diagnosed with AD, in Sweden during 1998-2017, and 1 300 561 population-based controls. Cox regression was used to compute hazard ratios (HRs) for subsequent risk of major depression identified from nationwide outpatient and inpatient diagnoses through 2018, adjusting for sociodemographic factors and prior mental …

A Dual-Model Machine Learning Framework For Predictive Maintenance Of Industrial Digital Press Components, Richmond Darko, Emmanuel Adabor

African Conference on Information Systems and Technology

This study presents a novel dual-model predictive maintenance framework designed to improve maintenance scheduling for components in industrial digital presses. The framework integrates two complementary approaches: a Threshold-Based Maintenance Approach (TBMA) for components operating within acceptable usage limits, and an Overdue Severity-Based Maintenance Approach (OSBMA) for those that have exceeded their expected lifespans or show signs of critical degradation. This study uses real-world operational data from a Konica Minolta C6000 press. It applies advanced machine learning models, including Gradient Boosting Machines and Random Forest for classification, and Generalized Additive Models (GAM) for Remaining Useful Life (RUL) prediction. The goal is …

Conceptualizing Sociotechnical Changes In Higher Education Institution Fundraising Practices Resulting From Popia Compliance, Tendani Mulanga Chimboza, Ronica Ramsout, Wallace Chigona

African Conference on Information Systems and Technology

This qualitative inquiry investigates the sociotechnical changes in fundraising practices of Higher Education Institutions (HEI) resulting from compliance with the Protection of Personal Information Act (POPIA) Act No 4 of 2013 in South Africa. POPIA imposes strict regulations for collection, processing, sharing and storage of personally identifiable information (PII). As the South African government continues to reduce subsidies in HEIs, a third-income stream has become important to support operational activities. A major source of a third-income stream for HEIs is fundraising. Fundraising practices are largely mediated through donor management systems (DMS) or Customer Relationship Management Systems (CRM) that rely on …

Gratifications That Contribute To Compulsive Youtube Use Among University Students, Mkhululi Tshepo Ncube, Zweithini Mabhena, Wallace Chigona

African Conference on Information Systems and Technology

This study investigated the gratifications contributing to compulsive YouTube use among university students. Compulsive YouTube use, marked by an inability to regulate consumption despite negative impacts to the user, is analysed through the Uses and Gratifications Theory (U&G) and Compulsive Internet Use (CIU). Specifically, the study examined how different gratifications—such as emotional support, habitual viewing, and escapism—drive compulsive use patterns. A cross-sectional survey strategy was employed, collecting data from 175 university students through structured online questionnaires. The study used Partial Least Squares Structural Equation Modelling (PLS-SEM) to test the relationships between the identified gratifications and compulsive usage behaviour. The findings …


How Can We Reduce Mental Health Disparities In Rural Areas?, Brenda Kinyumu Aug 2025

How Can We Reduce Mental Health Disparities In Rural Areas?, Brenda Kinyumu

Global Advocacy

On a regular day, rural areas face a shortage of healthcare providers (Physicians) and have limited access to healthcare for their physical illness. Adding mental health to the equation complicates the situation. Different communities have distinct needs, thus requiring solutions tailored for each community. It is crucial to assess the specific needs of each community and customize interventions accordingly. 1/5 of the rural population, which is roughly 6.5 million people, suffer from mental health illness (Morales et al., 2020). According to the Mental Health America website, the Rural suicide rate is 18.3 &20.5 per 100,0000 compared to the urban rate …
