AbstractThe aim of the study was to compare running performance of three competitive standards and to examine the effects of being promoted to a higher league in Norwegian football. One clubʼs first and second team were included. The first team consisted of professional soccer players playing at Level 2 (2015 season) and Level 1 (2016 season). The second team consisted of amateurs playing at Level 4. A fully automatic tracking system was used to examine running performance, divided into different running-speed categories and playing position. Forty-one matches were included containing 278 observations. Level 1 performed 61 and 51% sprinting compared to Level 2 and Level 4 but similar high-speed running. Similar high-speed running distances were observed only for the different playing positions at Level 1 compared to Level 2 and 4. The sprinting distance was greater for the central defender and attacker, and the number of accelerations was greater for central midfielders and wide midfielders’ playing at Level 1 compared to lower competitive standards. In conclusion, better competitive standards resulted in greater high-intensity actions than lower leagues in Norwegian soccer. Furthermore, only central defenders and attackers increased their high-intensity locomotions when the team was promoted.

Abstract
Background The aims of this study were to compare neoplasia detection rates for nontargeted biopsies (Seattle protocol) versus acetic acid-targeted biopsies (Portsmouth protocol) during Barrett’s surveillance and to explore feasibility, patient/clinician experience, acceptance, and barriers/enablers to study participation and implementation of the acetic acid technique.
Methods This was a mixed-methods feasibility study including a pilot multicenter, randomized, crossover trial with qualitative interviews. Patients under Barrett’s surveillance with no history of neoplasia were included. Patients underwent two endoscopies, one with each protocol, 8 weeks apart. Outcomes included recruitment and retention rates, neoplasia yield, and number of biopsies.
Results 200 patients were recruited from 6 centers, and 174 (87.0 %) underwent both procedures. Neoplasia prevalence was 4.7 % (9/192). High grade dysplasia and cancer were detected with both protocols. Five low grade dysplasias were detected (two with acetic acid, four with nontargeted biopsies; one lesion was detected with both techniques). A total of 2139 biopsies were taken in the nontargeted arm and 226 in the acetic acid arm. Both patients and clinicians found the acetic acid technique acceptable. Based on these data, a noninferiority, tandem, crossover trial would require an estimated 2828 patients.
Conclusions We demonstrated the feasibility of performing a crossover endoscopy trial in Barrett’s surveillance. Low neoplasia yield makes this design necessary and qualitative results demonstrated patient and clinician acceptance. The reduced numbers of biopsies suggest that the acetic acid technique could result in cost savings, providing the lack of missed pathology can be proven in a fully powered definitive trial.
Natural Compounds with Anti-BACE1 Activity as Promising Therapeutic Drugs for Treating Alzheimerʼs Disease

Published: October 2019

AbstractAlzheimerʼs disease is a neurodegenerative disease that leads to irreversible neuronal damage. Senile plaques, composed of amyloid beta peptide, is the principal abnormal characteristic of the disease. Among the factors involved, the secretase enzymes, namely, α secretase, beta-site amyloid precursor protein-cleaving enzyme, β secretase, and γ secretase, hold consequential importance. Beta-site amyloid precursor protein-cleaving enzyme 1 is considered to be the rate-limiting factor in the production of amyloid beta peptide. Research supporting the concept of inhibition of beta-site amyloid precursor protein-cleaving enzyme activity as one of the effective therapeutic targets in the mitigation of Alzheimerʼs disease is well accepted. The identification of natural compounds, such as β-amyloid precursor protein-selective beta-site amyloid precursor protein-cleaving enzyme inhibitors, and the idea of compartmentalisation of the beta-site amyloid precursor protein-cleaving enzyme 1 action have caused a dire need to closely examine the natural compounds and their effectiveness in the disease mitigation. Many natural compounds have been reported to effectively modulate beta-site amyloid precursor protein-cleaving enzyme 1. At lower doses, compounds like 2,2′,4′-trihydroxychalcone acid, quercetin, and myricetin have been shown to effectively reduce beta-site amyloid precursor protein-cleaving enzyme 1 activity. The currently used five drugs that are marketed and used for the management of Alzheimerʼs disease have an increased risk of toxicity and restricted therapeutic efficiency, hence, the search for new anti-Alzheimerʼs disease drugs is of primary concern. A variety of natural compounds having pure pharmacological moieties showing multitargeting activity and others exhibiting specific beta-site amyloid precursor protein-cleaving enzyme 1 inhibition as discussed below have superior biosafety. Many of these compounds, which are isolated from medicinal herbs and marine flora, have been long used for the treatment of various ailments since ancient times in the Chinese and Ayurvedic medical systems. The aim of this article is to review the available data on the selected natural compounds, giving emphasis to the inhibition of beta-site amyloid precursor protein-cleaving enzyme 1 activity as a mode of Alzheimerʼs disease treatment.

Published: October 2019

Abstract
Background Novel secondary flap options are paramount for patients who are not candidates for common reconstructive methods. The purpose of this study is to identify the prevalence of single arterial pedicle supplying both the gracilis muscle and medial thigh tissue carried in a profunda artery perforator (PAP) flap. Such a pedicle could allow the creation of a chimeric gracilis and PAP flap with a single-arterial anastomosis.
Methods We conducted a retrospective review of 157 lower extremity computed tomography (CT) angiograms to assess the vasculature of the thigh soft tissues. Imaging evaluation was supervised by a board-certified musculoskeletal radiologist.
Results Prevalence of a single-arterial pedicle to a gracilis and PAP flap in each patient was 59% (31% within the right leg and 28% in the left leg). Furthermore, 16% of patients had a common arterial pedicle in both lower extremities.
Conclusion Existence of a single-arterial pedicle to both the gracilis muscle and PAP flap tissues is frequently present in most patients in at least one lower extremity. This chimeric flap configuration could serve as a reconstructive avenue for patients, particularly those who have exhausted other more common flap options. Screening angiography is warranted in patients looking for this anatomic variation to establish its presence.
Nascent Malunion of an Isolated Intraarticular Fracture of the Ulnar Head
Authors: Nienstedt Frank , Mariacher Markus , Stuflesser Günther , Berger Wilhelm 
Published: October 2019

Abstract
Background Isolated fractures of the ulnar head are rare. Only few cases have been reported in literature.
Case Description We report a case of a 16-year-old student who was treated for an ulnar styloid fracture conservatively. An associated displaced intraarticular fracture of the ulnar head has been overlooked. He presented late in our clinic with a symptomatic nascent malunion of the ulnar head fracture. A corrective osteotomy by a palmar approach was performed. Fixation by screws was used with an excellent result at 7-year follow-up.
Literature Review The rare cases of isolated ulnar head fractures reported in literature were treated by open reduction and internal fixation only in case of fracture dislocation.
Clinical Relevance The authors highlight the fact that even a nascent malunion of an isolated intraarticular fracture of the ulnar head may be treated successfully by open reduction and internal fixation.

Authors: Sullivan Brianne J. , Maliha Samantha , Henderson Peter W. 
Published: October 2019

Abstract
Background Acquisition of microsurgical skill and clinical knowledge is the primary goal of a microsurgery fellowship. There has yet to be any comprehensive reporting in the literature of how American microsurgery fellows viewed their curricula and training at the conclusion of their fellowship year.
Methods An anonymous, electronic survey was developed and distributed to all 2016 to 2017 microsurgery fellows (n = 37) at the U.S.-based microsurgery fellowship programs (n = 23). Qualitative questions were assessed using either a Likert-type scale of 1 (not at all) to 5 (very), multiple choice, or free response.
Results Twenty-six of 37 fellows (70%) responded to the survey. Respondents reported a mean of 14.4 lectures offered, with a range of 0 to 100. Dry laboratory simulation training was formally incorporated into 32% of microsurgery fellowships and live animal simulation training was formally incorporated into 12%. The median number of free deep inferior epigastric perforator flap cases performed was 112.5, ranging from 60 to 230. A majority felt that an organized microsurgical educational curriculum would be “beneficial,” with 42% reporting that an organized microsurgery curriculum would be “very beneficial.” Twenty-six of the respondents (100%) said that they would choose to do a microsurgery fellowship again if given the choice.
Conclusion Respondent data show that microsurgery fellows are satisfied with training, clinical experience is variable but adequate, educational experiences and opportunities vary from program to program, simulation skills training are perceived to be underutilized, and a program-organized microsurgery curriculum is believed to be advantageous to optimize development of technical and clinical skills.
The “dissolving margins” of Elena Ferrante and the Neapolitan novels
Authors: Gibbons Alison 
Published: October 2019

AbstractUsing Elena Ferrante’s Neapolitan novels as case study, this article presents a cognitive approach to fictionality and authorial intention using Text World Theory and Mind-Modelling. It investigates two forms of ontological distortion: readers’ (mis)classification of the novels’ genre (as autofiction or autobiography) and the problem posed by the author’s pseudonymic identity. The analysis has three parts: first, I conduct a Text World analysis of the novels’ syntactic/stylistic similarities to autobiography and, in doing so, reveal its ontological structure; second, I consider the ontological liminality of narration and the ways in which readers build an authorial mind-model of Ferrante; thirdly, I explore the assessment of critics and/as readers of the text’s fictionality and the impact of Ferrante’s pseudonym on perceptions of authorial intentionality and the authorial mind-model. Ultimately, I argue that a cognitive approach offers greatest insight into readers’ interpretations of authors and of fictionality.
Narrative warfare
Authors: Nurminen Matias 
Published: October 2019

Abstract
This article studies the use of literature and narrative strategies of online antifeminist movements. These
movements classified under the umbrella term the manosphere, wage ideological narrative warfare to endorse a
misogynistic worldview. The case at hand concentrates on the radical faction of neomasculinity and its attempts to reinterpret the
Western canon of literature. I propose that neomasculine readings of novels such as Vladimir Nabokov’s Lolita are
careless interpretations that ground themselves on specific traits of the texts while ignoring others. These readings attempt to
evoke a sense of recognition in the community that believes in an alleged feminist conspiracy against men. Careless
interpretations borrow from post-truth rhetoric and the feminist literary theory tradition of reading against the grain. When
confronted over their controversial views, neomasculine figures renarrativize readings to benefit the promotion of neomasculine
perspectives. This strategic use of literature is part of the narrative warfare discussed in detail.
Adjusting to new “truths”
Authors: Schoofs Kim , Mieroop Dorien Van De 
Published: October 2019

AbstractIn this article, we study the diachronic (re)construction of repeated WWII-testimonies. Specifically, we scrutinize how shifting master narratives in the social context may affect how stories are told in a particular time and place. We selected testimonies by two Belgian concentration camp survivors – one Flemish and one Walloon – who both wrote down their story twice, namely in 1946 and 1985. By comparing the “same” diachronically dispersed stories – thus addressing the temporal dimension – and the differences in the narrators’ regional background – thus incorporating the spatial dimension – we study how overlapping and differing storytelling environments influenced the narratives’ construction. In the analyses, we adopt an interactional-sociolinguistic approach to illustrate the storytelling environments’ influence upon the story formulations and the relativity of what is presented as the “truth”, since the narrators continuously adjusted their stories and identities to fit with the ever-evolving storytelling context.
On phase retrieval via matrix completion and the estimation of low rank PSD matrices
Authors: Carlsson Marcus , Gerosa Daniele 
Published: October 2019

Abstract
Given underdetermined measurements of a positive semi-definite (PSD) matrix X of known low rank K, we present a new algorithm to estimate X based on recent advances in non-convex optimization schemes. We apply this in particular to the phase retrieval problem for Fourier data, which can be formulated as a rank 1 PSD matrix recovery problem. Moreover, we provide a theory for how oversampling affects the stability of the lifted inverse problem.
Radiation doses and decontamination effects in Minamisoma city: airborne and individual monitoring after the Fukushima nuclear accident

Published: October 2019

Abstract
After the Fukushima accident, airborne monitoring was implemented to measure airborne radiation. We examined the relationships between airborne and individual radiation monitoring and clarified the use of airborne monitoring to evaluate the effects of decontamination on residents’ received doses. We used the air dose rate data from four airborne monitors conducted between 2013 and 2016, and the dose data from four individual monitors (in which a total of 18 392 adults and 3650 children participated), conducted in Minamisoma City during the same period. We examined the Pearson correlation coefficients between the airborne and individual monitoring data and estimated exposure ratios (ERs; ratios of individual dose to air dose rates) among adults and children. We also estimated the effects of decontamination on residents’ doses based on airborne monitoring data, adjusting this for timing and dosing through propensity score matching, which were then compared to individual monitoring data. There were significant correlations between airborne and individual monitoring doses among adults and children, and more than 80% of residents showed a good estimation–observation agreement within a factor of two. The median of ERs was 0.304 and 0.250 among adults and children, respectively. There was a significant difference between the two. Effects of decontamination on residents’ doses estimated from airborne monitoring were significantly lower than those estimated from individual monitoring. These findings suggest that airborne monitoring can be used to estimate representative radiation doses within residential areas. It may be a useful tool for enhancing communication among stakeholders and supporting individual and policy decisions; however, it is less sensitive for evaluating individual effects of decontamination than individual monitoring. Combined use of airborne and individual monitoring also showed a lower median of ERs in children than in adults and in a Japanese government’s model, possibly due to prioritised decontamination for children and differences between their behavioral patterns.
Bioinspired growth of iron derivatives on mesoporous silica: effect on thermal degradation and fire behavior of polystyrene

Published: October 2019

Abstract
Aiming to investigate the influence of pore property of mesoporous material on thermal degradation and fire behavior of polystyrene (PS), the ultrafine iron derivatives were uniformly grown on the interior wall of SBA-15 via the coordination-induced assembly by bioinspired polydopamine (PDA). The resultant SBA-15@PDA@Fe was verified by various characterizations with the dominant component of FeOOH. Compared with PS composites with SBA-15, PS composites with SBA-15@PDA@Fe revealed the notably divergent alteration in thermal and thermal-oxidation degradation behavior, which was determined by the changed pore property. The iron derivatives in SBA-15 mesopores possessed the stronger affinity to aerobic volatiles than anaerobic volatiles (via π–π coordination), which inhibited the release of oxidatively decomposed products and enhanced thermal-oxidation stability. In addition, SBA-15@PDA@Fe was capable to preferentially improve limiting oxygen index, accompanied by the decrease of smoke production through suppressing smoke precursors. The glass transition temperature (T
g) of PS/SBA-15 was slightly increased via the bioinspired modification.
Integral fluctuation relations for entropy production at stopping times
Authors: Neri Izaak , Roldán Édgar , Pigolotti Simone , Jülicher Frank 
Published: October 2019

Abstract
A stopping time T is the first time when a trajectory of a stochastic process satisfies a specific criterion. In this paper, we use martingale theory to derive the integral fluctuation relation for the stochastic entropy production in a stationary physical system at stochastic stopping times T. This fluctuation relation implies the law , which states that it is not possible to reduce entropy on average, even by stopping a stochastic process at a stopping time, and which we call the second law of thermodynamics at stopping times. This law bounds the average amount of heat and work a system can extract from its environment when stopped at a random time. Furthermore, the integral fluctuation relation implies that certain fluctuations of entropy production are universal or are bounded by universal functions. These universal properties descend from the integral fluctuation relation by selecting appropriate stopping times: for example, when T is a first-passage time for entropy production, then we obtain a bound on the statistics of negative records of entropy production. We illustrate these results on simple models of nonequilibrium systems described by Langevin equations and reveal two interesting phenomena. First, we demonstrate that isothermal mesoscopic systems can extract on average heat from their environment when stopped at a cleverly chosen moment and that the second law at stopping times bounds the average extracted heat. Second, we demonstrate that the efficiency at stopping times of an autonomous stochastic heat engine, such as Feymann’s ratchet, can be larger than the Carnot efficiency and that the second law of thermodynamics at stopping times bounds its efficiency at stopping times.
Measurement of electric charges on foraging bumblebees (Bombus terrestris)
Authors: Montgomery C , Koh K , Robert D 
Published: October 2019

Abstract
Bumblebees carry electric charge. Almost always positive, this charge facilitates pollen transfer between bumblebee and flower during pollination and is likely to play a role in the detection of electric fields. Models of the Coulomb forces acting on pollen grains during pollination are predominantly based upon laboratory measurements of bumblebee charge. Using a novel method, the charges on bumblebees are measured outdoors for the first time. Outdoor bumblebees are found to carry similar positive charges to those previously measured in the laboratory. Bee charge is affected by local weather conditions, with the most positive charges being found on bees flying in warm, dry conditions. Results show that bee charges used in previous models of pollen transfer are representative of wild foraging bumblebees, and that pollen transfer between bee and flower is likely to be affected by local weather conditions.
Electrostatic formation of Liquid Marbles – Statistical model

Published: October 2019

Abstract
A statistical treatment is developed for the electrostatic transfer of particles from a powder bed to a pendent droplet during liquid marble and aggregate formation. The model uses Weibull statistics to calculate the probability of particle transfer events of a given size occurring, for the given electric field strength and geometry. This is used in Monte Carlo simulations of the transfer process. In this preliminary study, some of the most distinctive features of the experiments – transfer event size and spacing, scaling with driving potential – are well-captured using physically plausible parameter values. Other features, such as denuding of the particle bed, are less well reproduced, and require refinement.
Study of the effect of plasma treatment on the triboelectric properties of Polyethylene (PE) and Polypropylene (PP) slabs

Published: October 2019

Abstract
The dielectric barrier discharge (DBD) is a convenient way to modify the surface properties of polymers. The aim of this study is to evaluate the effect of atmospheric DBD treatment on the triboelectric properties of polymers in sliding contact. The experiments were carried out on two polymers that were rubbed against each other: PP and PE. The pairs of samples were exposed to the DBD, and then taken to a triboelectric test bench for friction charging. The distribution of electric potential at the surface of the tribocharged samples was measured by an electrostatic voltmeter. The triboelectric behavior of the considered polymers depends on the conditions of DBD treatment: thickness of the dielectric barrier and duration of the exposure to the non-thermal plasma.
