State of the art management practices for liver glycogen storage disorders: Results from an international survey among metabolic centres
Background: Liver glycogen storage disorders (GSDs) are rare inherited disorders of carbohydrate metabolism that are clinically characterized by hepatomegaly and fasting intolerance. This group of disorders comprises GSD Ia and Ib as well as the so-called ketotic GSDs including GSD III, VI, IX, XI and 0a. Although clinical practice guidelines exist for most GSD subtypes, diagnostics, treatment and monitoring differ significantly among metabolic centres. The aim of this study was to gain insight into current clinical practice for liver GSDs. Methods: An international web-based survey was performed among health care professionals involved in the care of individuals with liver GSDs. Results: Sixty-seven respondents from 28 different countries caring for approximately 2650 liver GSD patients completed the survey. While the diagnostic approach was generally consistent, significant differences among metabolic centres are still observed with respect to monitoring parameters and treatment approaches. Reasons for these differences are local availability of management tools and treatment options, the rarity of the different GSD subtypes, the experiences of health care professionals, and the existence of extreme phenotypes. Conclusion: The development of a standard set of outcomes for patients with liver GSDs is warranted as a reference for both daily care and the evaluation of safety and efficacy of future therapies. For various parameters that serve as valuable outcome measures, tools and target values should be better defined

Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

The Right to Strike under the United States Constitution: Theory, Practice, and Possible Implications for Canada
Answering critics of the Canadian Supreme Court's judgment in B.C. Health, the author argues that the Court laid the foundation for a principled and durable doctrine protecting constitutional labour rights, one that goes directly to the heart of the matter — the inequality of workers’ power in the employment relation. In the author’s view, two paths could lead from B.C. Health to the recognition of Charter protec- tion for a right to strike: one that treats the right as an accessory to col- lective bargaining, and one that upholds the right directly on the basis of the Charter values of equality and participation. The author supports the latter approach, contending that constitutional rights should be defined in relation to fundamental values, in a way that is not contingent on time-bound or fact-sensitive assessments about the role of strikes within a particular collective bargaining regime. Although a Charter right to strike may involve the courts in difficult choices about when to defer to legislative policy decisions, and courts may lack the institutional capac- ity to deal effectively with labour law issues, the author points out that judges can look to ILO standards for expert guidance. Noting that the U.S. experience in this area might be of considerable use to Canadians, the author concludes by providing an overview of American case law concerning a constitutional right to strike.Peer reviewe
Kinetics of absorption of carbon dioxide in aqueous piperazine solutions
In the present work the absorption of carbon dioxide into aqueous piperazine (PZ) solutions has been studied in a stirred cell, at low to moderate temperatures, piperazine concentrations ranging from 0.6 to 1.5 kmol m- 3, and carbon dioxide pressures up to 500 mbar, respectively. The obtained experimental results were interpreted using the DeCoursey equation [DeCoursey, W., 1974. Absorption with chemical reaction: development of a new relation for the Danckwerts model. Chemical Engineering Science 29, 1867-1872] to extract the kinetics of the main reaction, 2 PZ + CO2 → PZCOO- + PZH+, which was assumed to be first order in both CO2 and PZ. The second-order kinetic rate constant was found to be 70 m3 mol- 1 s- 1 at a temperature of 298.15 K, with an activation temperature of 4.1 × 103 K. Also, the absorption rate of CO2 into partially protonated piperazine solutions was experimentally investigated to identify the kinetics of the reaction 2 PZH+ + CO2 → H+ PZCOO- + PZH22 +. The results were interpreted using the Hogendoorn approach [Hogendoorn, J., Vas Bhat, R., Kuipers, J., Van Swaaij, W., Versteeg, G., 1997. Approximation for the enhancement factor applicable to reversible reactions of finite rate in chemically loaded solutions. Chemical Engineering Science 52, 4547-4559], which uses the explicit DeCoursey equation with an infinite enhancement factor which is corrected for reversibility. Also, this reaction was assumed to be first order in both reactants and the second-order rate constant for this reaction was found to be (0.28 ± 0.10) m3 mol- 1 s- 1 at 298.15 K.
G-Rank: Unsupervised Continuous Learn-to-Rank for Edge Devices in a P2P Network
Ranking algorithms in traditional search engines are powered by enormous training data sets that are meticulously engineered and curated by a centralized entity. Decentralized peer-to-peer (p2p) networks such as torrenting applications and Web3 protocols deliberately eschew centralized databases and computational architectures when designing services and features. As such, robust search-and-rank algorithms designed for such domains must be engineered specifically for decentralized networks, and must be lightweight enough to operate on consumer-grade personal devices such as a smartphone or laptop computer. We introduce G-Rank, an unsupervised ranking algorithm designed exclusively for decentralized networks. We demonstrate that accurate, relevant ranking results can be achieved in fully decentralized networks without any centralized data aggregation, feature engineering, or model training. Furthermore, we show that such results are obtainable with minimal data preprocessing and computational overhead, and can still return highly relevant results even when a user’s device is disconnected from the network. G-Rank is highly modular in design, is not limited to categorical data, and can be implemented in a variety of domains with minimal modification. The results herein show that unsupervised ranking models designed for decentralized p2p networks are not only viable, but worthy of further research.https://github.com/awrgold/G-RankComputer Scienc
