Diabetes Technology—Continuous Subcutaneous Insulin Infusion Therapy and Continuous Glucose Monitoring in Adults: An Endocrine Society Clinical Practice Guideline

Abstract: Objective: To formulate clinical practice guidelines for the use of continuous glucose monitoring and continuous subcutaneous insulin infusion in adults with diabetes. Participants: The participants include an Endocrine Society-appointed Task Force of seven experts, a methodologist, and a medical writer. The American Association for Clinical Chemistry, the American Association of Diabetes Educators, and the European Society of Endocrinology co-sponsored this guideline. Evidence: The Task Force developed this evidence-based guideline using the Grading of Recommendations, Assessment, Development, and Evaluation system to describe the strength of recommendations and the quality of evidence. The Task Force commissioned one systematic review and used the best available evidence from other published systematic reviews and individual studies. Consensus Process: One group meeting, several conference calls, and e-mail communications enabled consensus. Committees and members of the Endocrine Society, the American A...

Cobalt and Copper Hexacyanoferrate Modified Carbon Fiber Microelectrode as an All‐Solid Potentiometric Microsensor for Hydrazine

Abstract: This article reports on the novel mixed cobalt and copper hexacyanoferrate (CoCuHCF)-modified carbon fiber cylinder microelectrode (CFCME) and its application to potentiometric determination of highly toxic hydrazine. The substrate CFCMEs were fabricated in a standard manner using carbon fibers of 7 µm in diameter. The CoCuHCF film was deposited electrochemically by cycling the potential between 0 and +1.0 V (vs. Ag/AgCl) in a solution containing the precursor salts. It exhibited good chemical stability in the pH range from 1 to 9. The effects of the coverage/thickness of the CoCuHCF coating, of the pH of a measurement solution, and of the activation of the sensor, on the potentiometric response to hydrazine were examined in detail. The potentiometric behavior of CoCuHCF film in the presence of hydrazine, with the potential (emf) slope of –55 mV/decade, was compared with those of four single metal HCF films (CoHCF, CuHCF, FeHCF, and NiHCF) prepared in the same way, and the possible role of the CoCuHCF film components is explored and discussed. The emf versus log CHyd calibration plot was linear over 3 orders of magnitude, from 1.0×10–6 to 1.0×10–3 mol/L, with a correlation coefficient of 0.995. The limit of detection was found to be 5×10–7 mol/L. The response times of 10 to 30 s and the temperature coefficients of ca–2.7 mV/°C were obtained at various hydrazine concentrations. The repeatability of measurements was very good with the relative standard deviation ranging from 3 to 4% (n=10), depending on hydrazine concentration. The selectivity of the reported microsensor was found excellent, except in the case of a few negatively charged interferents for which it was greately improved by an additional Nafion coating. The useful lifetime of the all-solid microsensor was found to be more than 2 months when stored in air.

A connectionist approach to automatic transcription of polyphonic piano music

Abstract: In this paper, we present a connectionist approach to automatic transcription of polyphonic piano music. We first compare the performance of several neural network models on the task of recognizing tones from time-frequency representation of a musical signal. We then propose a new partial tracking technique, based on a combination of an auditory model and adaptive oscillator networks. We show how synchronization of adaptive oscillators can be exploited to track partials in a musical signal. We also present an extension of our technique for tracking individual partials to a method for tracking groups of partials by joining adaptive oscillators into networks. We show that oscillator networks improve the accuracy of transcription with neural networks. We also provide a short overview of our entire transcription system and present its performance on transcriptions of several synthesized and real piano recordings. Results show that our approach represents a viable alternative to existing transcription systems.

2020 taxonomic update for phylum Negarnaviricota (Riboviria: Orthornavirae), including the large orders Bunyavirales and Mononegavirales

Abstract: In March 2020, following the annual International Committee on Taxonomy of Viruses (ICTV) ratification vote on newly proposed taxa, the phylum Negarnaviricota was amended and emended. At the genus rank, 20 new genera were added, two were deleted, one was moved, and three were renamed. At the species rank, 160 species were added, four were deleted, ten were moved and renamed, and 30 species were renamed. This article presents the updated taxonomy of Negarnaviricota as now accepted by the ICTV.
