 Cardiac Care_ Detecting Drug Use

Cardiac care can help detect drug use through irregular heart rhythms, elevated blood pressure, or abnormal ECG results. Certain drugs, like stimulants or opioids, impact heart function. Identifying these signs during cardiac evaluations aids in timely diagnosis, improving treatment and reducing risks of serious complications like heart attacks or arrhythmias.

Cardiac Care and Drug Use Detection:

The cardiovascular system is highly sensitive to various substances, especially drugs like cocaine, methamphetamine, opioids, and certain prescription medications. During routine or emergency cardiac evaluations, healthcare providers may identify signs of drug use based on changes in heart function.

  1. Electrocardiogram (ECG or EKG):
    An ECG measures the electrical activity of the heart. Certain drugs cause arrhythmias (irregular heartbeats), prolonged QT intervals, or ST segment changes—red flags that may suggest stimulant or depressant drug use.

  2. Heart Rate and Blood Pressure:
    Elevated heart rate (tachycardia) and high blood pressure can be signs of stimulant use (e.g., cocaine, amphetamines). Conversely, opioids may cause bradycardia (slow heart rate) and hypotension.

  3. Cardiac Enzymes and Biomarkers:
    Blood tests measuring troponin and other cardiac markers can detect heart damage caused by drugs like cocaine, which can lead to heart attacks even in young, otherwise healthy individuals.

  4. Imaging Tests:
    Echocardiograms or MRIs may reveal structural heart issues like cardiomyopathy, which can result from chronic drug abuse.

  5. Patient History and Symptoms:
    Chest pain, palpitations, shortness of breath, or syncope (fainting) during drug use may prompt deeper cardiac investigation and toxicology screening.

Global Lighthouse Network

Smart, sustainable manufacturing: 3 lessons from the Global Lighthouse Network Launched in 2018, when more than 70% of factories struggled to scale digital transformation beyond isolated pilots, the Global Lighthouse Network set out to identify the world’s most advanced production sites and create a shared learning journey to up-level the global manufacturing community. In the past seven years, the network has grown from 16 to 201 industrial sites in more than 30 countries and 35 sectors, including the latest cohort of 13 new sites. This growing community of organizations is setting new standards for operational excellence, leveraging advanced technologies to drive growth, productivity, resilience and environmental sustainability. But what exactly is a Global Lighthouse and what has the network achieved? What is the Global Lighthouse Network? The Global Lighthouse Network is a community of operational facilities and value chains that harness digital technologies at scale to ac...

Multi-Modal Data

Multi-Task Federated Split Learning Across Multi-Modal Data with Privacy Preservation With the advancement of federated learning (FL), there is a growing demand for schemes that support multi-task learning on multi-modal data while ensuring robust privacy protection, especially in applications like intelligent connected vehicles. Traditional FL schemes often struggle with the complexities introduced by multi-modal data and diverse task requirements, such as increased communication overhead and computational burdens. In this paper, we propose a novel privacy-preserving scheme for multi-task federated split learning across multi-modal data (MTFSLaMM). Our approach leverages the principles of split learning to partition models between clients and servers, employing a modular design that reduces computational demands on resource-constrained clients. To ensure data privacy, we integrate differential privacy to protect intermediate data and employ homomorphic encryption to safeguard client m...

Satellite Communications

3D printed and circularly polarized 28 GHz patch antenna array for small satellite communications This paper presents the design, fabrication, and testing of a high-gain compact 2 × 2 circularly polarized patch antenna array using 3D printing technology for small satellite 5G communication at 28 GHz. The proposed antenna demonstrates high efficiency and a low profile, addressing the limitations in design flexibility associated with traditional PCB fabrication methods . The 2 × 2 array configuration, incorporating via fences, coaxial vertical feedlines, and a sequentially rotated phased feed network, enhances the antenna's bandwidth and axial ratio bandwidth while maintaining compactness, crucial for space-constrained satellite applications. Simulations optimized key antenna parameters, including reflection coefficient , gain, and axial ratio. Measurement results validated the simulations, showing an impedance bandwidth of 6.8 GHz and an axial ratio bandwidth of 3.1 GHz, with a ...
