The economic impact of COVID-19: losses and resilience factors

This study proposes a numerical assessment of the economic loss associated with COVID-19 across 46 countries. We estimate these losses by forecasting each country’s counterfactual GDP, that is, the GDP that would have occurred in the absence of the pandemic, using a hybrid WT–QPS...

A systematic review of environmental factors in AI-based fall risk prediction models for community-dwelling older adults

Falls commonly occur in home environments, where conditions can increase fall risk. Identification and mitigation of environmental hazards are critical components of fall prevention. However, artificial intelligence (AI)-based fall prediction models have largely focused on indivi...

The first 72 hours of acute pancreatitis: patterns of variability in early clinical decision-making

To assess real-world adherence to evidence-based international guidelines in the early management of acute pancreatitis (AP), and to identify how variability in clinical decision-making is distributed during the first 72 h of care. This multicentre, cross-sectional survey was con...

Application of digital technologies for agricultural knowledge sharing in research and development organizations and their impact on organizational knowledge management in northern Ethiopia

Digital technologies are increasingly recognized as essential tools for achieving sustainable development by enhancing knowledge sharing and innovation within agricultural systems. Despite their potential, empirical evidence on the extent of digital technology adoption, its deter...

Prevalence and factors associated with anxiety and depression among cancer patients undergoing chemotherapy: a cross-sectional study at a private tertiary hospital in Dhaka, Bangladesh

Cancer patients are at increased risk of psychological distress, particularly anxiety and depression, due to the prolonged disease course, prognosis uncertainty, and intensive treatment demands. However, limited evidence exists on the mental health status of cancer patients recei...

Scale-Indexed Drift Geometry in Loophole-Free Bell Experiments: Preregistered NIST Calibration

This version reports a preregistered cross-platform calibration of a proposed Bell-functional drift signature on six official NIST loophole-free photonic runs. Under the frozen primary analysis, one run-level slope was positive and five were negative; the median slope was -2.5571...

Molecular clues to the rescue: differentiating gestational and non-gestational ovarian choriocarcinoma—a case report

Non-gestational ovarian choriocarcinoma (NGOC) is a rare and aggressive tumor. Distinguishing NGOC from its gestational counterpart especially in the reproductive age group often presents as a diagnostic challenge. The treatment and prognoses of both differ significantly. Molecul...

The central role of fatigue and sleep in health behaviors during the COVID-19 pandemic

To explore the associations between perceived fatigue and various health behaviors in a Brazilian adult sample using network analysis during the COVID-19 pandemic. Data were collected via an online questionnaire between July 2020 and February 2021, including sociodemographic info...

Development of an authenticated cryptography algorithm to enhance the security of Internet of Things closed-circuit television devices

The security and efficiency of Internet of Things (IoT) Closed-Circuit Television (CCTV) devices become crucial with the increased popularity of CCTV surveillance systems. Security is provided by traditional encryption techniques but with the large computational overhead that mak...

Detection of lung cancer using Kronecker mobile forward harmonic net

Cancer is one of the most hazardous illnesses, which has been increasing the rate of mortality. In both men and women, lung cancer is recognized as the most widespread form of malignancy. The formation of unregulated cell growth in the lungs creates lung cancer. The earlier stage...

Functional trait-mediated limiting similarity shapes weed biomass acquisition, fecundity, and reproductive phenology

According to the theories of limiting similarity and life history trade-offs, (i) the probability of species coexistence decreases as interspecific similarity increases, and (ii) stronger competition intensity may accelerate reproductive phenology. Based on these theories, we pre...

A survey on secure and intelligent data transmission in fog IoT enabled smart farming environments

Fog computing is a decentralized computing paradigm that provides distributed computing capabilities closer to the edge devices. The Internet of Things (IoT) is a wireless network used for collecting and transmitting data over the internet. Fog computing and IoT together enhance...

Tailored hierarchical zeolites via greener synthesis for the pyrolytic conversion of peanut shell waste

Peanut shell is a high volume globally produced waste. Catalytic pyrolysis is proposed for its valorization. Hierarchical ZSM-5 zeolites were evaluated as solid catalysts to improve bio oil composition. Starch, cheap, renewable and safe polymeric carbohydrate was employed as a bi...

Psychiatric education in medical training: a scoping review of curricular innovations, teaching strategies, and assessment methods

Mental disorders contribute substantially to global disease burden, yet persistent deficiencies remain in medical trainees’ readiness to identify, diagnose, and treat patients with mental health conditions. Main barriers include stigma, outdated curricula, insufficient clinical p...
