Lower-limb reference data of children are necessary to identify and quantify abnormalities, but these are limited and when present restricted to specific joints or muscles.\r\nMethods:\r\nThis is the first study that encompasses the aforementioned parameters from a single group of 34 typically developing children aged 5\u201317\u2009years. Left and right values were averaged for each participant, and then the mean and standard deviation calculated for the entire sample. The data set was tested for statistical significance (p\u2009<\u20090.05).\r\nResults:\r\nJoint angle reference values are mostly consistent with previously published standards, although there is a large variability in the existing literature. All muscle strength distributions, except for M. quadriceps femoris, differ significantly from the maximum value of 5. The mean number of repetitions of heel-rise test is 12\u2009±\u20095. Selective voluntary motor control shows that all distributions, except for M. quadriceps femoris, differ significantly from the maximum value of 2.\r\nConclusion:\r\nSince typically developing children do not match expectations and reference values from the available literature and clinical use, this study emphasizes the importance of normative data. Excessively high expectations lead to typically developing children being falsely underestimated and affected children being rated too low. This is of great relevance for therapists and clinicians.", "language" : "English", "issn" : "1863-2548", "doi" : "10.1177/18632521241234768", "bibtexKey": "Scherff_2024" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2fb597bac915ac4be9f277967bed8c0f3/annettegugel", "tags" : [ "Frequency","Measurements","PD","Power","Range","Transformers","UHF","in","of" ], "intraHash" : "fb597bac915ac4be9f277967bed8c0f3", "interHash" : "e0c573668f250ccc47b13c39e78349f5", "label" : "Frequency Range of UHF PD Measurements in Power Transformers.", "user" : "annettegugel", "description" : "", "date" : "2024-03-07 15:25:19", "changeDate" : "2024-03-07 15:25:19", "count" : 1, "pub-type": "article", "journal": "Energies 2023", "year": "2023", "url": "", "author": [ "Stefan Tenbohlen","Chandra Prakash Beura","Wojciech Sikorski","Ricardo Albarracín Sánchez","Bruno Albuquerque de Castro de Castro","Michael Beltle","Pascal Fehlmann","Martin Judd","Falk Werner","Martin Siegel" ], "authors": [ {"first" : "Stefan", "last" : "Tenbohlen"}, {"first" : "Chandra Prakash", "last" : "Beura"}, {"first" : "Wojciech", "last" : "Sikorski"}, {"first" : "Ricardo", "last" : "Albarracín Sánchez"}, {"first" : "Bruno Albuquerque de Castro", "last" : "de Castro"}, {"first" : "Michael", "last" : "Beltle"}, {"first" : "Pascal", "last" : "Fehlmann"}, {"first" : "Martin", "last" : "Judd"}, {"first" : "Falk", "last" : "Werner"}, {"first" : "Martin", "last" : "Siegel"} ], "volume": "16","number": "3", "doi" : "10.3390/en16031395", "bibtexKey": "tenbohlen2023frequency" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2dda7c7842f8b627c739b615bde678e28/inspo5", "tags" : [ "Far","TS","angle","corresponding","estimation","force","joint","maximum","muscle","of","on","range","the","working" ], "intraHash" : "dda7c7842f8b627c739b615bde678e28", "interHash" : "12a4bf98a06f2d283088a3622f5e5b0d", "label" : "Considerations on the human Achilles tendon moment arm for in vivo triceps surae muscle--tendon unit force estimates", "user" : "inspo5", "description" : "", "date" : "2022-07-19 11:10:29", "changeDate" : "2022-07-19 09:10:56", "count" : 2, "pub-type": "article", "journal": "Scientific Reports", "year": "2020", "url": "https://doi.org/10.1038/s41598-020-76625-x", "author": [ "Denis Holzer","Florian Kurt Paternoster","Daniel Hahn","Tobias Siebert","Wolfgang Seiberl" ], "authors": [ {"first" : "Denis", "last" : "Holzer"}, {"first" : "Florian Kurt", "last" : "Paternoster"}, {"first" : "Daniel", "last" : "Hahn"}, {"first" : "Tobias", "last" : "Siebert"}, {"first" : "Wolfgang", "last" : "Seiberl"} ], "volume": "10","number": "1","pages": "19559","abstract": "Moment arm-angle functions (MA-a-functions) are commonly used to estimate in vivo muscle forces in humans. However, different MA-a-functions might not only influence the magnitude of the estimated muscle forces but also change the shape of the muscle's estimated force-angle relationship (F-a-r). Therefore, we investigated the influence of different literature based Achilles tendon MA-a-functions on the triceps surae muscle--tendon unit F-a-r. The individual in vivo triceps torque--angle relationship was determined in 14 participants performing maximum voluntary fixed-end plantarflexion contractions from 18.3°þinspace±þinspace3.2° plantarflexion to 24.2°þinspace±þinspace5.1° dorsiflexion on a dynamometer. The resulting F-a-r were calculated using 15 literature-based in vivo Achilles tendon MA-a-functions. MA-a-functions affected the F-a-r shape and magnitude of estimated peak active triceps muscle--tendon unit force. Depending on the MA-a-function used, the triceps was solely operating on the ascending limb (nþinspace=þinspace2), on the ascending limb and plateau region (nþinspace=þinspace12), or on the ascending limb, plateau region and descending limb of the F-a-r (nþinspace=þinspace1). According to our findings, the estimated triceps muscle--tendon unit forces and the shape of the F-a-r are highly dependent on the MA-a-function used. As these functions are affected by many variables, we recommend using individual Achilles tendon MA-a-functions, ideally accounting for contraction intensity-related changes in moment arm magnitude.", "issn" : "2045-2322", "doi" : "10.1038/s41598-020-76625-x", "bibtexKey": "Holzer2020" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/220aac70d92fb99729b91ffe1c3adb342/inspo5", "tags" : [ "Dynamic","Motion","Myofascial","Range","Static","Stretching","of" ], "intraHash" : "20aac70d92fb99729b91ffe1c3adb342", "interHash" : "998f4bb115946256f369303b1f4fc79c", "label" : "Effect of Static Stretching, Dynamic Stretching, and Myofascial Foam Rolling on Range of Motion During Hip Flexion: A Randomized Crossover Trial", "user" : "inspo5", "description" : "", "date" : "2022-07-19 11:10:29", "changeDate" : "2022-07-19 09:10:56", "count" : 2, "pub-type": "article", "journal": "Journal of Strength and Conditioning Research","publisher":"Ovid Technologies (Wolters Kluwer Health)", "year": "2022", "url": "https://doi.org/10.1519%2Fjsc.0000000000003517", "author": [ "Tobias Siebert","Lars Donath","Mischa Borsdorf","Norman Stutzig" ], "authors": [ {"first" : "Tobias", "last" : "Siebert"}, {"first" : "Lars", "last" : "Donath"}, {"first" : "Mischa", "last" : "Borsdorf"}, {"first" : "Norman", "last" : "Stutzig"} ], "editor": [ "Tobias Siebert" ], "editors": [ {"first" : "Tobias", "last" : "Siebert"} ], "volume": "36","number": "3","pages": "680--685", "language" : "English", "doi" : "10.1519/jsc.0000000000003517", "bibtexKey": "Siebert_2022" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2fed533daa0ea8d702d0ba5fe8b7593ff/annettegugel", "tags" : [ "30","9","Automotive","Charging","Emission","Field","Inductive","MHz","Magnetic","Range","Systems","in","kHz","of","the","\u2013" ], "intraHash" : "fed533daa0ea8d702d0ba5fe8b7593ff", "interHash" : "58d9e006aaf0c70cbc08030d8b25e801", "label" : "Magnetic Field Emission of Automotive Inductive Charging Systems in the 9 kHz \u2013 30 MHz Range", "user" : "annettegugel", "description" : "", "date" : "2022-02-14 14:04:42", "changeDate" : "2022-02-14 13:04:42", "count" : 2, "pub-type": "conference", "year": "2021", "url": "", "author": [ "Manuel Haug","Michael Beltle","Stefan Tenbohlen" ], "authors": [ {"first" : "Manuel", "last" : "Haug"}, {"first" : "Michael", "last" : "Beltle"}, {"first" : "Stefan", "last" : "Tenbohlen"} ], "eventtitle" : "2021 Asia-Pacific International Symposium on Electromagnetic Compatibility (APEMC)", "venue" : "Nusa Dua -

Three hundred images with 0.67- or 5-mm section thickness were compressed to one of five compression ratios ranging from reversible compression to 15:1. The fidelity of each compressed image was measured by five radiologists' visual analyses (distinguishable or indistinguishable from the original) and the three metrics.

Three hundred images with 0.67- or 5-mm section thickness were compressed to one of five compression ratios ranging from reversible compression to 15:1. The fidelity of each compressed image was measured by five radiologists' visual analyses (distinguishable or indistinguishable from the original) and the three metrics. The Spearman rank correlation coefficients of the PSNR, HDR-VDP, and MS-SSIM values with the number of readers responding as indistinguishable were 0.86, 0.94, and 0.86, respectively.
