Objective: To investigate the feasibility, reliability, and validity of the Modified forward hop (MFH) test in participants after ACL reconstruction (ACLR).
Design: Reliability study.
Setting: Assessments were administered at different clinical locations in Germany and Switzerland by the same 2 investigators.
Participants: Forty-eight active individuals participated in this study (N=48).
Main Outcome Measures: The participants performed MFHs and Forward hops for distance in a predetermined order. The feasibility of the MFH was quantified with proportions of successfully executed attempts and Pearson's χ2 test. Its reliability was estimated using intraclass correlation coefficient (ICC) and standard error of measurement (SEM). Test validity was explored using Pearson's product moment correlation analyses.
Results: Fewer failed attempts were recorded among the participants (age: 30 [Standard deviation 11] years; 22 women, 26 (13) months post-surgery) when compared with the Forward hop for distance test (25/288 trials; 9% vs 72/288 trials; 25%). Within-session ICC values were excellent (>0.95) for both types of Forward hop tests, independent of the side examined. The SEM values were comparable between the Modified (injured: 5.6 cm, uninjured: 5.9 cm) and the classic Forward hop (injured: 4.3 cm, uninjured: 7.2 cm).
Conclusion: The MFH is a feasible, reliable, and valid tool for judging neuromuscular performance after ACLR. If the aim of a hop for distance incorporates enhanced perceived or real landing safety, landing on both feet should be used.
A dazzling collection from across the African continent and diaspora - here SHORT STORY DAY AFRICA has assembled the best nineteen stories from their 2013 competition. Food is at the centre of stories from authors emerging and established, blending the secular, the supernatural, the old and the new in a spectacular celebration of short fiction. Civil wars, evictions, vacations, feasts and romances - the stories we bring to our tables that bring us together and tear us apart.
Feathers are arranged in a precise pattern in avian skin. They first arise during development in a row along the dorsal midline, with rows of new feather buds added sequentially in a spreading wave. We show that the patterning of feathers relies on coupled fibroblast growth factor (FGF) and bone morphogenetic protein (BMP) signalling together with mesenchymal cell movement, acting in a coordinated reaction-diffusion-taxis system. This periodic patterning system is partly mechanochemical, with mechanical-chemical integration occurring through a positive feedback loop centred on FGF20, which induces cell aggregation, mechanically compressing the epidermis to rapidly intensify FGF20 expression. The travelling wave of feather formation is imposed by expanding expression of Ectodysplasin A (EDA), which initiates the expression of FGF20. The EDA wave spreads across a mesenchymal cell density gradient, triggering pattern formation by lowering the threshold of mesenchymal cells required to begin to form a feather bud. These waves, and the precise arrangement of feather primordia, are lost in the flightless emu and ostrich, though via different developmental routes. The ostrich retains the tract arrangement characteristic of birds in general but lays down feather primordia without a wave, akin to the process of hair follicle formation in mammalian embryos. The embryonic emu skin lacks sufficient cells to enact feather formation, causing failure of tract formation, and instead the entire skin gains feather primordia through a later process. This work shows that a reaction-diffusion-taxis system, integrated with mechanical processes, generates the feather array. In flighted birds, the key role of the EDA/Ectodysplasin A receptor (EDAR) pathway in vertebrate skin patterning has been recast to activate this process in a quasi-1-dimensional manner, imposing highly ordered pattern formation.
Feathers in Reverse
(2014)
Feathers in Reverse is the ideal gift for a loved one who is scared of poetry. It engages and immerses readers with the luring subtlety of a serpent. Themes treated include good and evil, heaven and earth, man and woman, birth and death, urbanism and rural life, wealth and poverty. As much as the poet highlights salient issues and conflicts in everyday life, he suggests answers to burning problems as well. A common thread runs through the over 300 poems feathered and featured in this collection. The notion of the 'feather' is cross-cultural. It reminds us of the feather used as a pen in ancient Europe and the 'red feather' that is stuck on the caps of African notables as a mark of distinction. Feathers in Reverse is a magic pudding to be sampled, shared and indulged.
The presented work inside this thesis aims to raise the degree of automation in analog circuit design. Therefore, a framework was developed to provide the necessary mechanisms in order to carry out a fully automated analog circuit synthesis, i.e., the construction of an analog circuit fulfilling all previously defined (electrical) specifications. Nowadays, analog circuit design in general is a very time consuming process compared to a digital design flow. Due to its discrete nature, the digital design process is highly automated and thus very efficient compared to analog circuit design. In modern Very-Large-Scale integration (VLSI) circuits the analog parts are mostly just a small portion of the overall chip area. Although this small portion is known to consume a major part of the needed workforce. Paired with product cycles which constantly get shorter, the time needed to develop the analog parts of an integrated circuit (IC) becomes a determinant factor. Apart from this, the ongoing progress in semiconductor processing technologies promises more speed with less power consumption on smaller areas, forcing the IC developers to keep track with the technology nodes in order to maintain competitiveness. Analog circuitry exhibits the inherent property of being hard to reuse, as porting from one technology node to another imposes critical changes for operating conditions (e.g., supply voltage) - mostly leading to a full redesign for most of the analog modules. This productivity gap between digital and analog design resembles the primary motivation for this thesis. Due to the availability of commercial sizing tools, this work deliberately focuses on the construction of circuit topologies in distinction to parameter synthesis, which can be obtained with a dedicated sizing tool. The focus on circuit construction allows the development of a framework which allows a full design space exploration. This thesis describes the needed concepts and methods to realize a deterministic, explorative analog synthesis framework. Despite this, a reference implementation is presented, which demonstrates the applicability in current analog design flows.
In this paper we will explore the similarities and differences between two feature logic-based approaches to the composition of semantic representations. The first approach is formulated for Lexicalized Tree Adjoining Grammar (LTAG, Joshi and Schabes 1997), the second is Lexical Ressource Semantics (LRS, Richter and Sailer 2004) and was first defined in Head-driven Phrase Structure Grammar. The two frameworks have several common characteristics that make them easy to compare: 1 They use languages of two sorted type theory for semantic representations. 2. They allow underspecification. LTAG uses scope constraints while LRS provides component-of contraints. 3 They use feature logics for computing semantic representations. 4. they are designed for computational applications. By comparing the two frameworks we will also point outsome characteristics and advantages of feature logic-based semantic computation in genereal.
Many analyses of existential sentences have focused attention on determining which of its elements constitutes the logical subject and predicate, and this has proven to be a not uncontroversial topic of research. Some, from both syntactic and semantic points of view, have argued that there is a subject (cf. Williams 1994) others that it is a predicate (cf. Moro 1997). Similarly, some have argued that the associate NP is a logical subject, others that it is apredicate (Higginbotham 1987).
One logical possibility that has not (to my knowledge) been pursued in the linguistics literature is that these statements are not of the form subject-predicate, a possibility that has been taken up in the philosophical literature by P.F. Strawson (1959). He claims that there are such statements and that their form is simpler than that of subject-predicate statements because it does not, and cannot, involve an expression that makes reference to an individual. Not involving reference to an individual, these sentences are therefore are made true by different means than a subject-predicate statement whose truth, in the simplest cases, depends on the denotation of the subject being a member of the denotation of the predicate. Of interest from the point of view of the present discussion is his claim that existential statements are examples of this kind of statement, which he calls a feature-placing statement. The truth of a statement of the form feature-placer requires that something with the set of features denoted by the associate NP exist at the location or coordinates expressed by the placer. In an existential sentence we can take the associate NP as the feature-denoting expression and the coda-XP as the placer.
Endoscopic retrograde cholangiopancreatography (ERCP) offers an effective interventional option for treating symptomatic chronic pancreatitis. Endoscopic pancreatic sphincterotomy is performed to facilitated endoscopic treatment. Pancreatic duct strictures can be treated by inserting plastic stents, and a 10 Fr endoprosthesis is adequate in many cases. Before stent insertion, hydrostatic balloon dilation is needed in some cases. Pancreatic stones can be removed with a dormia basket, but combining ERCP and extracorporeal shockwave lithotripsy (ESWL) is often most effective.
Standard and advanced endoscopic treatment approaches are delineated in this article and include stricture dilation with a Soehendra retriever, cSEMS placement and multi-stenting.
Several translation scholars have recognised translation as a form of discourse mediation or discourse presentation (see, for example, Mossop 1998). In line with this, "universals" of translation have also been re-framed in the larger context of discourse mediation, as mediation universals rather than something strictly translationspecific (Ulrych 2009). In the present article, this line of enquiry is developed by comparing some of the alleged universals of translation, namely standardization and explicitation, with insights from literary and narratological studies on the nature of discourse presentation. The notion of reportive or interpretative interference (Sternberg 1982) and Fludernik’s (1993) claim that all represented discourse is typical and schematic in nature seem to bear curious resemblance to the notion of standardization or normalization, posited as a possible universal of translation (Mauranen & Kujamäki 2004). Drawing on the results of my earlier research (Kuusi 2011), I present examples of free indirect discourse (FID) used in Dostoevsky’s novel Crime and Punishment with their translations into Finnish. Analyzing the translations, I demonstrate how in
translations, the narratological and literary-theoretical notions of reportive interference and typification/schematization coincide with the translation-theoretical notions of explicitation and standardization.
Background and Aims: Fecal biomarkers are important non-invasive markers monitoring disease activity in inflammatory bowel disease (IBD). We compared the significance of fecal eosinophil cationic protein (fECP) and fecal calprotectin (fCal).
Methods: fECP and fCal were measured in patients with Crohn's disease (CD, n = 97), ulcerative colitis (UC, n = 53), Clostridioides difficile infection (CDI, n = 9), primary food allergy (PFA, n = 11), pollen-associated food allergy (n = 25) and non-inflammatory controls (n = 78). Results were correlated with clinical and endoscopic IBD activity scores.
Results: fECP was significantly elevated in CD, UC, CDI and PFA compared to controls. fCal was significantly increased in CD, UC and CDI. fECP had lower diagnostic accuracy than fCal (area under the curve (AUC) = 0.88) in differentiating between endoscopically active and inactive patients with IBD (AUC = 0.77, ROC analysis). In contrast to fCal, fECP correlated negatively with age and levels were also elevated in clinically and endoscopically inactive patients with IBD <45 years (endoscopically inactive IBD vs controls; AUC for fECP = 0.86; AUC for fCal = 0.62). However, in those patients with low inflammatory activity (fCal <250 mg/kg), high fECP indicated the need for treatment modification or surgery (fECP <200 µg/kg = 22%; 200–600 µg/kg = 44%; >600 µg/kg = 82%) at month 48 of follow-up.
Conclusions: fECP is a diagnostic and prognostic marker in young patients with IBD in remission.
