Promoting Sustainable Prescribing—A Case Study Presenting Experiences From Two Swedish Drug and Therapeutics Committees

Pharmacology Research &Perspectives, Volume 14, Issue 4, August 2026.
ABSTRACT During the past two decades, it has become evident that pharmaceuticals is an emerging environmental problem. In this study, we present the experiences from two Swedish Drug & Therapeutics Committees (DTCs) on how they integrate environmental considerations into their formularies and continuous professional education activities.

A Fuzzy‐Logic and Machine Learning‐Based Framework for Water Quality Index Classification in Extensive and Intensive Aquaculture Systems

Engineering Reports, Volume 8, Issue 6, June 2026.
This study presents an Internet of Things (IoT)‐to‐Cloud framework for real‐time monitoring and prediction of the Water Quality Index (WQI) across both extensive and intensive aquaculture systems. By integrating Fuzzy Logic biological thresholds with ML classification, the Random Forest model achieves over 99.5% accuracy in both environments ...

Nonlinearity-Induced Spur Analysis in Fractional-N Synthesizers With ΔΣ Quantization Cancellation

IEEE Open Journal of the Solid-State Circuits Society
A fractional-N frequency synthesizer with low total jitter [e.g., <50fsrms, accounting for both phase noise (PN) and spurs] is essential for enabling the emerging 5G/6G and other high-speed wireless communication standards (e.g., WiFi-6/7).

A 8.9 to 10-GHz −97.86-dBc Reference Spur Pulser-Free Continuous Charge Pump Sub-Sampling PLL With Fine-Tunable Dead-Zone Generator in 65-nm CMOS Process

IEEE Access
A sub-sampling PLL (SSPLL) with a pulser-free continuous charge pump (CCP) and a bootstrap sampling front-end has been developed and the reference spurs can be significantly suppressed by eliminating cyclic high impedance charge pump operation. A counter-

No App, No Entry: Conceptualizing Digital Technology Captivity in Service Access

Psychology &Marketing, Volume 43, Issue 5, Page 974-985, May 2026.
ABSTRACT We introduce Digital Technology Captivity (DTC), a form of consumer vulnerability that arises when digital technologies become the mandatory gateway to essential services. When access is tied to systems that feel unfamiliar, complex, or intimidating—and when preferred alternatives are limited—consumers may experience heightened vulnerability ...

Isocitrate Dehydrogenase Mutations in Cancer: From Bench to Bedside Applications

MedComm, Volume 7, Issue 5, May 2026.
Mutant isocitrate dehydrogenase affects multiple cancer types. Alterations in IDH1 and IDH2 result in abnormal enzyme activity, leading to the overproduction of D‐2‐hydroxyglutarate (D‐2HG). This metabolite disrupts cellular metabolism and epigenetic regulation, driving cancer initiation, progression, and metastasis.
