A Systematic Review of Machine-Learning Solutions in Anaerobic Digestion.

The use of machine learning (ML) in anaerobic digestion (AD) is growing in popularity and improves the interpretation of complex system parameters for better operation and optimisation. This systematic literature review aims to explore how ML is currently employed in AD, with particular attention to the challenges of implementation and the benefits of integrating ML techniques. While both lab and industry-scale datasets have been used for model training, challenges arise from varied system designs and the different monitoring equipment used.

Pd-induced quenching of the UV emission from Gd ions in phosphate glass.

This paper reports on the influence of Pd ions on the ultraviolet emission from Gd, investigated in barium phosphate glass as model matrix. The glasses were prepared by the melting technique and characterized by X-ray diffraction (XRD), Fourier transform-infrared (FT-IR) spectroscopy, optical absorption, and photoluminescence (PL) spectroscopy including decay kinetics assessment. The XRD data confirmed the amorphous nature of the glasses, whereas FT-IR spectra indicated the basic structural features of PO tetrahedra.

Primary carcinoid tumor in an ileal conduit.

Carcinoid tumors are neuroendocrine tumors that typically arise in the gastrointestinal tract. We present the case of a 74-year-old woman with a primary carcinoid tumor in an ileal conduit urinary diversion who presented with gross hematuria. We also provide a brief review of relevant reports.

Long-term efficacy of sildenafil and tachyphylaxis effect.

Purpose: We observed that patients who initially responded to sildenafil frequently became resistant to it with time. We evaluated the long-term efficacy of sildenafil.

Materials And Methods: A telephone survey was conducted of patients during the first year of sildenafil usage, and another one was completed 2 years later of the same group.
