Posterior ankle impingement syndrome: A systematic four stage approach
Venue: World journal of orthopedics

Posterior ankle impingement syndrome (PAIS) is a common injury in athletes engaging in repetitive plantarflexion, particularly ballet dancers and soccer players. Despite the increase in popularity of the posterior two portal hindfoot approach, concerns with the technique remain, including; the technical difficulty, relatively steep learning curve, and difficulty performing simultaneous anterior ankle arthroscopy. The purpose of the current literature review is to provide comprehensive knowledge about PAIS, and to describe a systematic four stage approach of the posterior two portal arthroscopy. The etiology, clinical presentation, diagnostic strategies are first introduced followed by options in conservative and surgical management. A detailed systematic approach to posterior hindfoot arthroscopy is then described. This technique allows for systematic review of the anatomic structures and treatment of the bony and/or soft tissue lesions in four regions of interest in the hindfoot (superolateral, superomedial, inferomedial, and inferolateral) The review then discusses biological adjuncts and postoperative rehabilitation and ends with a discussion on the most recent clinical outcomes after posterior hindfoot arthroscopy for PAIS. Although clinical evidence suggests high success rates following posterior hindfoot arthroscopy in the short and mid term it may be limited in the pathology that can be addressed due to the technical skills required, but the systematic four stage approach of the posterior two portal arthroscopy may improve upon this problem.
[Ankle impingement. Indications and arthroscopic therapy]
Venue: Der Unfallchirurg

Ankle impingement syndromes are one of the most frequent chronic and posttraumatic pathologies of the ankle joint. Anterior and posterior impingement result from the abutting of anatomical structures leading to pain and limitation in the range of motion of the ankle joint. Ankle impingement can be classified based on the localization or the underlying cause. Besides chronic ankle pain, further symptoms are movement and load dependent swelling of the ankle joint and limitations in dorsiflexion and plantar flexion. The clinical symptoms and physical examination play an essential role in diagnosing soft tissue impingement, whereas various imaging techniques are important for the diagnostics of bony impingement. From a therapeutic perspective, conservative treatment should be initially attempted. If non operative treatment fails, arthroscopic resection and debridement of the underlying cause is nowadays the standard method of surgical treatment. With a current complication rate of approximately 3 ankle arthroscopy is a safe operative method, which is associated with a high postoperative rate of patient satisfaction and significant relief of symptoms.
Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) for materials characterization

Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) are highly versatile methodologies for 2D and 3D materials characterization. The high spatial resolution of SEM and TEM, from nano to microscale in both imaging and chemical characterization modes, is highly complementary to other nondestructive materials characterization techniques covered later in this book. In this chapter we cover the basic principles underpinning the use of electron microscopy, and give an overview of the core methodologies available in SEM and TEM. The range of useful signals generated by electron matter interactions are described, and related to the SEM and TEM techniques that make use of them. The application SEM and TEM to the evaluation of key microstructural features of materials including surface topography, grain size, and local chemistry is discussed, and an overview of topical applications given.
Investigation of a broadband refractory metal metamaterial absorber at terahertz frequencies.
Venue: Applied optics

A broadband, polarization independent, and wide angle refractory metal metamaterial absorber is numerically investigated at terahertz frequencies, which consists of a periodic array of a chromium metallic loop and a chromium metallic film separated by a polyimide layer. Results show that a higher than 90% broadband absorption can be achieved for the range of frequencies from 1.00 through 2.43 THz, and the full absorption width at half maximum can attain 110.80% which is considerably larger than in previously reported results. Moreover, the greater than 90% broadband absorption response can still be maintained when the incidence angle increases to 45deg. The physical origin of the proposed broadband absorber originates from localized surface plasmon resonances of the single metallic loop resonator. Furthermore, the designed concept also can be achieved in the visible and near infrared region by rationally designing the dimensions of the absorber. This compact design has potential applications in stealth technology, energy harvesting, and thermal imaging.

Comparison of SOAP and REST Based Web Services Using Software Evaluation Metrics

The usage of Web services has recently increased. Therefore, it is important to select right type of Web services at the project design stage. The most common implementations are based on SOAP (Simple Object Access Protocol) and REST (Representational State Transfer Protocol) styles. Maintainability of REST and SOAP Web services has become an important issue as popularity of Web services is increasing. Choice of the right approach is not an easy decision since it is influenced by development requirements and maintenance considerations. In the present research, we present the comparison of SOAP and REST based Web services using software evaluation metrics. To achieve this aim, a systematic literature review will be made to compare REST and SOAP Web services in terms of the software evaluation metrics.
Gender and homosexuality attitudes across religious groups from the 1970s to 2014: Similarity, distinction, and adaptation.
Venue: Social science research

This study uses General Social Survey data to compare gender and homosexuality across American religious groups from the 1970s to 2014, examining three possible patterns for how evangelical attitudes relate to those of other groups: (1) they are similar; (2) they are different, but move together over time; (3) they are different and converge or diverge over time. Evangelical gender attitudes regarding work and family issues are more conservative than those of all other groups, but are adaptive to broad trends, changing at a rate similar to those of other groups. Evangelical attitudes toward the morality of homosexuality and same sex marriage are more conservative than those of all other religious groups, and their rate of change is slower over time. Separate trends on the two issues suggest that gender and sexuality attitude change is decoupled, especially among evangelicals who are adapting more on gender while increasingly distinguishing themselves on same sex relationships. A three stage process of religious tension appears to characterize evangelical identity building: (1) similarity, (2) distinction, and (3) adaptation.
The impact of acute stress on hormones and cytokines, and how their recovery is affected by music evoked positive mood
Venue: Scientific reports

Stress and recovery from stress significantly affect interactions between the central nervous system, endocrine pathways, and the immune system. However, the influence of acute stress on circulating immune endocrine mediators in humans is not well known. Using a double blind, randomized study design, we administered a CO2 stress test to n 143 participants to identify the effects of acute stress, and recovery from stress, on serum levels of several mediators with immune function (IL 6, TNF a, leptin, and somatostatin) as well as on noradrenaline, and two hypothalamic pituitary adrenal axis hormones (ACTH and cortisol) Moreover, during a 1 h recovery period, we repeatedly measured these serum parameters, and administered an auditory mood induction protocol with positive music and a neutral control stimulus. The acute stress elicited increases in noradrenaline, ACTH, cortisol, IL 6, and leptin levels. Noradrenaline and ACTH exhibited the fastest and strongest stress responses, followed by cortisol, IL 6 and leptin. The music intervention was associated with more positive mood, and stronger cortisol responses to the acute stressor in the music group. Our data show that acute (CO2) stress affects endocrine, immune and metabolic functions in humans, and they show that mood plays a causal role in the modulation of responses to acute stress.
Genre Adaptive Semantic Computing and Audio Based Modelling for Music Mood Annotation
Venue: IEEE Transactions on Affective Computing

This study investigates whether taking genre into account is beneficial for automatic music mood annotation in terms of core affects valence, arousal, and tension, as well as several other mood scales. Novel techniques employing genre adaptive semantic computing and audio based modelling are proposed. A technique called the ACTwg employs genre adaptive semantic computing of mood related social tags, whereas ACTwg SLPwg combines semantic computing and audio based modelling, both in a genre adaptive manner. The proposed techniques are experimentally evaluated at predicting listener ratings related to a set of 600 popular music tracks spanning multiple genres. The results show that ACTwg outperforms a semantic computing technique that does not exploit genre information, and ACTwg SLPwg outperforms conventional techniques and other genre adaptive alternatives. In particular, improvements in the prediction rates are obtained for the valence dimension which is typically the most challenging core affect dimension for audio based annotation. The specificity of genre categories is not crucial for the performance of ACTwg SLPwg. The study also presents analytical insights into inferring a concise tag based genre representation for genre adaptive music mood analysis.
A finite element perspective on non linear FFT based micromechanical simulations

Fourier solvers have become efficient tools to establish structure property relations in heterogeneous materials. Introduced as an alternative to the finite element (FE) method, they are based on fixed point solutions of the Lippmann Schwinger type integral equation. Their computational efficiency results from handling the kernel of this equation by the fast Fourier transform (FFT) However, the kernel is derived from an auxiliary homogeneous linear problem, which renders the extension of FFT based schemes to nonlinear problems conceptually difficult. This paper aims to establish a link between FE based and FFT based methods in order to develop a solver applicable to general history dependent and time dependent material models. For this purpose, we follow the standard steps of the FE method, starting from the weak form, proceeding to the Galerkin discretization and the numerical quadrature, up to the solution of nonlinear equilibrium equations by an iterative Newton Krylov solver. No auxiliary linear problem is thus needed. By analyzing a two phase laminate with nonlinear elastic, elastoplastic, and viscoplastic phases and by elastoplastic simulations of a dual phase steel microstructure, we demonstrate that the solver exhibits robust convergence. These results are achieved by re using the nonlinear FE technology, with the potential of further extensions beyond small strain inelasticity considered in this paper.
FFT, FMM, or Multigrid? A comparative Study of State Of the Art Poisson Solvers for Uniform and Nonuniform Grids in the Unit Cube
Venue: SIAM J. Sci. Comput.

From molecular dynamics and quantum chemistry, to plasma physics and computational astrophysics, Poisson solvers in the unit cube are used in many applications in computational science and engineering. In this work, we benchmark and discuss the performance of the scalable methods for the Poisson problem which are used widely in practice: the fast Fourier transform (FFT) the fast multipole method (FMM) the geometric multigrid (GMG) and algebraic multigrid (AMG) Our focus is on solvers supporting high order, highly nonuniform discretizations. To allow comparisons with standard libraries we also compare adaptive solvers with solvers specialized for problems on regular grids, that is, FFT and regular stencil multigrid, since both are very popular algorithms for several practical applications. For the multigrid, we use the finite element variant of a high performance geometric multigrid (HPGMG) benchmark. In total we compare five different codes, three of which are developed in our group. Our FFT, GMG, and.
Prediction in OLAP Data Cubes
Venue: J. Inf. Knowl. Manag.

Online analytical processing (OLAP) provides tools to explore data cubes in order to extract the interesting information, it refers to techniques used to query, visualise and synthesise the multidimensional data. Nevertheless OLAP is limited on visualisation, structuring and exploring manually the data cubes. On the other side, data mining allows algorithms that offer automatic knowledge extraction, such as classification, explanation and prediction algorithms. However, OLAP is not capable of explaining and predicting events from existing data; therefore, it is possible to make a more efficient online analysis by coupling data mining and OLAP to allow the user to assist in this new task of knowledge extraction. In this paper, we will carry on within works achieved in this theme and we suggest to extend the abilities of OLAP to prediction (enhancing the OLAP abilities and techniques by introducing a predictive model based on a data mining algorithms) The model is calculated on the aggregated data, and prediction is done on detailed missing data. Our approach is based on regression trees and neural networks; it consists to predict facts having a missed measures value in the data cubes. The user will have in his disposition, a new platform called PredCube, that offers the possibility to query, visualise and synthesise the multidimensional data, and also to predict missing values in the data cube using three data mining methods, and evaluate the quality of the prediction by comparing the average error and the execution time given by each one.
A novel type of dynamic controlled atmosphere storage based on the respiratory quotient (RQ DCA)

A novel type of dynamic controlled atmosphere storage (RQ DCA) was developed to control O 2 and CO 2 partial pressures in storage containers for apple fruit automatically, based on measurements of the stored fruit respiratory quotient (RQ) 'Granny Smith' apples were stored under RQ DCA and the effect on fruit quality immediately after storage as well as during subsequent shelf life was investigated and compared to the effect of regular CA and regular CA storage with 1 MCP (SmartFresh SM treatment. The RQ DCA system managed to control O 2 and CO 2 partial pressures in the storage container in an autonomous way. During RQ DCA storage, the RQ breakpoint was found to vary between 0.25 kPa and 0.4 kPa O 2 However, difficulties to obtain a reliable RQ measurement were observed at very low oxygen levels due to reduced fruit respiration and when the pressure of the storage container increases due to increased atmosphere pressure due to leakiness of the storage container. Superficial scald was found to be controlled almost completely during storage with RQ DCA and the effect remained visible during up to 14 days of shelf life. Magness Taylor firmness and skin color (hue angle) were found to be significantly higher after RQ DCA storage compared to conventional CA storage and were comparable to these of fruit stored with regular CA after 1 MCP treatment up to 7 days of shelf life at 18 degC. In fruit ethanol concentrations were found to be very low 1 indicating the RQ DCA system managed to store the fruit close to the anaerobic compensation point but the fruit metabolism did not shift from aerobic respiration to fermentation.
The Relation Between Child Versus Parent Report of Chronic Fatigue and Language/Literacy Skills in School Age Children with Cochlear Implants
Venue: Ear and hearing

Preliminary evidence suggests that children with hearing loss experience elevated levels of chronic fatigue compared with children with normal hearing. Chronic fatigue is associated with decreased academic performance in many clinical populations. Children with cochlear implants as a group exhibit deficits in language and literacy skills; however, the relation between chronic fatigue and language and literacy skills for children with cochlear implants is unclear. The purpose of this study was to explore subjective ratings of chronic fatigue by children with cochlear implants and their parents, as well as the relation between chronic fatigue and language and literacy skills in this population.  Nineteen children with cochlear implants in grades 3 to 6 and one of their parents separately completed a subjective chronic fatigue scale, on which they rated how much the child experienced physical, sleep/rest, and cognitive fatigue over the past month. In addition, children completed an assessment battery that included measures of speech perception, oral language, word reading, and spelling.  Children and parents reported different levels of chronic child physical and sleep/rest fatigue. In both cases, parents reported significantly less fatigue than did children. Children and parents did not report different levels of chronic child cognitive fatigue. Child report of physical fatigue was related to speech perception, language, reading, and spelling. Child report of sleep/rest and cognitive fatigue was related to speech perception and language but not to reading or spelling. Parent report of child fatigue was not related to children's language and literacy skills.  Taken as a whole, results suggested that parents under estimate the fatigue experienced by children with cochlear implants. Child report of physical fatigue was robustly related to language and literacy skills. Children with cochlear implants are likely more accurate at reporting physical fatigue than cognitive fatigue. Clinical practice should take fatigue into account when developing treatment plans for children with cochlear implants, and research should continue to develop a comprehensive model of fatigue in children with cochlear implants.

Fault detection for networked systems with uncertain time delay and packet dropout using delta operator
Venue: 2016 IEEE 11th Conference on Industrial Electronics and Applications (ICIEA)

This paper addresses the problem of observer based fault detection for networked control systems (NCSs) with uncertain time delays and data packet dropouts. The uncertain time varying delays and packet dropouts of NCSs are modeled as parameter uncertainties of the NCSs and a stochastic variable satisfying Bernoulli distribution, respectively. Combining with the delta operator theory, a new discrete model is constructed to depict the behavior of the NCSs. Then, based on the established model, an observer based H fault detection filter is proposed to guarantee the stability of the delta operator system and the sufficient conditions of the H performance for the filtering error system are derived with linear matrix inequalities (LMIs) and Lyapunov Krasovskii functional technique. The parameters of the filter are solved via LMI toolbox. A simulation example is provided to illustrate the effectiveness of the proposed method.
Assessment of Global Incidence and Mortality of Hospital treated Sepsis. Current Estimates and Limitations.
Venue: American journal of respiratory and critical care medicine

Reducing the global burden of sepsis, a recognized global health challenge, requires comprehensive data on the incidence and mortality on a global scale.  To estimate the worldwide incidence and mortality of sepsis and identify knowledge gaps based on available evidence from observational studies.  We systematically searched 15 international citation databases for population level estimates of sepsis incidence rates and fatality in adult populations using consensus criteria and published in the last 36 years.  The search yielded 1,553 reports from 1979 to 2015, of which 45 met our criteria. A total of 27 studies from seven high income countries provided data for metaanalysis. For these countries, the population incidence rate was 288 (95% confidence interval [CI] 215 386; t 0.55) for hospital treated sepsis cases and 148 (95% CI, 98 226; t 0.99) for hospital treated severe sepsis cases per 100,000 person years. Restricted to the last decade, the incidence rate was 437 (95% CI, 334 571; t 0.38) for sepsis and 270 (95% CI, 176 412; t 0.60) for severe sepsis cases per 100,000 person years. Hospital mortality was 17% for sepsis and 26% for severe sepsis during this period. There were no population level sepsis incidence estimates from lower income countries, which limits the prediction of global cases and deaths. However, a tentative extrapolation from high income country data suggests global estimates of 31.5 million sepsis and 19.4 million severe sepsis cases, with potentially 5.3 million deaths annually.  Population level epidemiologic data for sepsis are scarce and nonexistent for low and middle income countries. Our analyses underline the urgent need to implement global strategies to measure sepsis morbidity and mortality, particularly in low and middle income countries.
