Replication Data for: Measurements of perfluoro-n-heptane and perfluoro-n-octane absorption cross-sections from 300 to 350 K
No full textThis dataset includes the absorption cross-section measurements used in 'Measurements of perfluoro-n-heptane and perfluoro-n-octane absorption cross-sections from 300 to 350 K' by Ishtiak et al. (2023a). The dataset includes (1) the absorption cross-sections for perfluoro-n-heptane [n-C7F16], labeled as PFC7. (2) the absorption cross-sections for perfluoro-n-octane [n-C8F18], labeled as PFC8. Nine absorption cross-sections are provided for each compound, labeled by the sample temperature from 300 to 350 K. All measurements were made using an ABB Bomem DA8 Fourier Transform InfraRed (FTIR) spectrometer. The original cross-section files have an uncertainty at 3 standard deviations, while the updated files (tagged V2) have an uncertainty at 2 standard deviations (consistent with the description in the published paper)
Replication Data for: Measurements of infrared absorption cross-sections for chloroiodomethane and 2-iodopropane from 305 to 340 K
No full textThis dataset includes the infrared absorption cross-section measurements used in 'Measurements of infrared absorption cross-sections for chloroiodomethane and 2-iodopropane from 305 to 340 K' by Ishtiak et al. (submitted, 2025). The dataset includes: (1) the absorption cross-sections for chloroiodomethane (CH2ICl), labeled as CH2ICl; (2) the absorption cross-sections for 2-iodopropane ((CH3)2CHI), labeled as (CH3)2CHI. Three absorption cross-sections are provided for each compound, labeled by the sample temperature from 300 to 340 K. All measurements were made using an ABB Bomem DA8 Fourier Transform InfraRed (FTIR) spectrometer. These cross-section files have an uncertainty at 2 standard deviations. The dataset also includes density functional theory geometries and unscaled and scaled frequencies for all conformers of chloroiodomethane and 2-iodopropane. These calculations use four density functionals, B3LYP, ωB97X, B2PLYP, and DSD-BLYP with and without the D3 dispersion correction across three basis sets: def2-SVP, def2-TZVPPD, and def2-QZVPPD
Replication Data for: Measurements of perfluoro-n-hexane and perfluoro-2-methylpentane infrared absorption cross-sections from 298 to 350 K

(2023b). The dataset includes (1) the absorption cross-sections for perfluoro-n-hexane [n-C6F14], labeled as nPFC6. (2) the absorption cross-sections for perfluoro-2-methylpentane [i-C6F14], labeled as iPFC6. Nine absorption cross-sections are provided for each compound, labeled by the sample temperature from 298 to 350 K. All measurements were made using an ABB Bomem DA8 Fourier Transform InfraRed (FTIR) spectrometer. The original cross-section files have an uncertainty at 3 standard deviations, while the updated files (tagged V2) have an uncertainty at 2 standard deviations (consistent with the description in the published paper)

Synergistic effects of creatine supplementation and resistance training in the management of knee osteoarthritis: A narrative review
No full textKnee osteoarthritis (KOA) is a common joint disorder anda leading cause of disability. Although there is no cure,management strategies focus on conservativeapproaches such as pharmacotherapy, nonpharmacologicalsupplementation, physical therapy (PT),and exercise. Pharmacological treatments are widely usedfor pain relief but carry risks of long-term adverse effectsand do not enhance joint or muscle health. Nonpharmacologicalsupplements, including glucosamineand chondroitin-sulphate, are frequently used, althoughtheir effectiveness remains debated. However, PT,particularly resistance training (RT), has shown significantbenefits in improving muscle strength and function inKOA. Creatine supplementation (CS) has recentlyemerged as a promising non-pharmacologicalintervention, particularly when combined with RT. Studiesindicate that while CS alone shows limited benefits inKOA, its combination with RT significantly enhancesmuscle strength, lean mass, physical function, and qualityof life by replenishing phosphocreatine stores, which fuelhigh-intensity muscle contractions during RT.Additionally, CS appears to be safe in short and mid-termuse according to the available studies. Even thoughevidence has shown positive effects of CS without anysignificant adverse effects, very few studies with smallsample sizes have been published in the literatureregarding KOA, reporting varying results. We recommendthat future studies should include larger sample sizes andstandardized measures to strengthen the evidence bas
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
