AbstractLeft ventricular outflow tract pseudoaneurysm is an uncommon complication following aortic valve replacement (AVR), occurring most frequently secondary to endocarditis. We present a case of a 47-year-old female with a history of intravenous drug abuse and a past surgical history of two AVRs (2001 and 2009 with aortic root replacement for endocarditis) who presented with symptoms of lower extremity weakness. Subsequent radiologic imaging revealed the presence of a left ventricular outflow tract pseudoaneurysm, which was surgically managed with a homologous conduit.

Authors: Bhamidipaty Madhu , Mees Barend , Wagner Timothy 
Published: April 2016

AbstractWhile the intra-aortic balloon pump (IABP) itself has many useful and life-saving indications, it has a high complication rate, up to 30% in some studies. This report discusses the surgical removal and subsequent vascular repair in a patient with a ruptured and subsequently entrapped IABP and reviews the literature on the presentation and management of this rare but major complication.
Complete Resolution of Wegener’s Granulomatosis Lung Granuloma After Aortic Root Replacement
Authors: Edmondson Sarah-Jayne , Attaran Saina , Rosendahl Ulrich 
Published: April 2016

AbstractWegner’s granulomatosis (WG) is an autoimmune systemic vasculitis that results in necrotizing granulomas. We report a WG patient with a lung granuloma and aortic root dilatation, who underwent aortic root replacement on cardiopulmonary bypass (CPB). Intraoperatively, the patient suffered an aortic dissection, which was repaired immediately under deep hypothermic circulatory arrest (DHCA). Follow-up imaging showed complete granuloma resolution, despite absence of immunosuppressive therapy. Immune stimulation following CPB is well described; here, the opposite was observed and DHCA effects are discussed.

Published: April 2016

AbstractThis case illustrates the complexities of performing a primary percutaneous intervention in a patient with chronic Type A aortic aneurysm and dissection with contraindications for surgical management. We also discuss the significant risk that the patient had to overcome to survive an undiagnosed aortic dissection and an acute ST elevation myocardial infarction.
This is a Poem/Afto einai ena Poiima: Graffiti, public space and poetry in the contemporary Athenian cityscape
Authors: Fragopoulos George 
Published: April 2016

Abstract
While most responses to contemporary Greek cultural production have referenced the ongoing economic and social crises, not as much attention has been paid directly to the art that has arisen directly out of such pressures. This article focuses on one small mode of cultural production, QR Code Poetry, an amalgam of graffiti, poetry and technology. Code Poetry comments on contemporary Greek social and political landscapes and is clearly indebted to larger global political and aesthetic movements as well. The brainchild of artists and poets Theodoros Papatheodorou and Ioannis Dimitriadis, Code Poetry is an art form that critiques neo-liberal ideology and its role in dismantling both the contemporary welfare state and any notion of a public commons. Code Poetry achieves these goals by making city space itself an integral component of the art object itself, suggesting that the relationship between the observer and the artwork must be a politicized one in order to produce any potential critique.
Argentina era una fiesta: Ocio, modernidad y presente constante en la comedia sofisticada durante el primer peronismo
Authors: Hopfenblatt Alejandro Kelly 
Published: April 2016

Abstract
A principios de la década de 1940 el cine argentino comenzó un proceso de aburguesamiento y sofisticación, buscando nuevos argumentos y modos de representación. Entre los principales referentes de este cambio se destacó Carlos Schlieper, quien, en la segunda mitad de la década, dirigió un conjunto de films que presentaban un universo burgués con jóvenes alocados y caprichosos y tramas centradas en las relaciones amorosas. Ambientados en un universo idílico alejado de problemáticas sociales, significó una aproximación novedosa al mundo de las elites, en el marco de las profundas transformaciones que acaecían en los primeros años del gobierno peronista. En un contexto de fuerte modernización del país y alteración de la estructura social, sus comedias muestran sin denunciarla a una burguesía que no se avergüenza de su condición, alterando los discursos cinematográficos previos sobre el ocio, la movilidad social y las pautas de consumo.

Relative performance of antisymmetric angle-ply laminated stiffened hypar shell roofs with cutout in terms of static behavior
Authors: Chowdhury Puja B. , Mitra Anirban , Sahoo Sarmila 
Published: April 2016

AbstractA review of literature reveals that bending analysis of laminated composite stiffened hypar shells with cutout have not received due attention. Being a doubly ruled surface, a skewed hypar shell fulfils aesthetic as well as ease of casting requirements. Further, this shell allows entry of north light making it suitable as civil engineering roofing units. Hypar shell with cutout subjected to uniformly distributed load exhibits improved performances with stiffeners. Hence relative performances of antisymmetric angle-ply laminated composite stiffened hypar shells in terms of displacements and stress resultants are studied in this paper under static loading. A curved quadratic isoparametric eight noded element and three noded beam elements are used to model the shell surface and the stiffeners respectively. Results obtained from the present study are compared with established ones to check the correctness of the present approach. A number of additional problems of antisymmetric angle-ply laminated composite stiffened hypar shells are solved for various fibre orientations, number of layers and boundary conditions. Results are interpreted from practical application standpoints and findings important for a designer to decide on the shell combination among a number of possible options are highlighted.
Numerical simulation of tests for the evaluation of the performance of the reinforced concrete slabs strengthening by FRCM
Authors: Anania Laura , Badalá Antonio , D’Agata Giuseppe 
Published: April 2016

AbstractIn this work the attention is focused to the numerical simulation of the experimental bending tests carried out on a total of six reinforced concrete r.c. plates the latter aimed to provide a basic understanding of the its performance when strengthened by Fiber Reinforced Cementitius Matrix (FRCM) Composites. Three of those were used as control specimens. The numerical simulation was carried out by LUSAS software. A good correlation between the FE results and data obtained from the test, both in the load–deformation behavior and the failure load was highlighted. This permits to prove that applied strengthening system gives back an enhancement 2.5 times greater in respect of the unreinforced case. A greater energy dissipation ability and a residual load-bearing capacity makes the proposed system very useful in the retrofitting as well as in the case of strengthening of bridge structures. Based on the validation of the FE results in bending, the numerical analysis was also extended to characterize the behavior of this strengthening system in tensile.
Those eyes don’t lie: a case of osmotic demyelination syndrome in a patient with hepatic encephalopathy
Authors: Murphy Caleb J. , Cathcart Peter L. , Olson Andrew P.J. 
Published: April 2016

Abstract
Osmotic demyelination syndrome (ODS), previously known as central pontine myelinolysis, is a rare neurological condition characterized by demyelination of the pons or extrapontine areas including the midbrain, thalamus, basal nuclei, and cerebellum, resulting in upper motor neuron dysfunction and pseudobulbar palsy. We report a case of a 45-year-old woman with a history of alcohol dependence and end stage liver disease complicated by hepatic encephalopathy who developed symptoms suspicious of recurrent hepatic encephalopathy and experienced a generalized seizure during an inpatient stay. After 10 days of treatment with no improvement, it was noted that the patient had locked-in syndrome and that her sodium levels had rapidly risen 2 days prior. This led to a clinical suspicion of ODS, which was confirmed on T2-weighted MRI and subsequently on autopsy. In this clinical vignette, we review the clinical presentation, prognosis, and diagnostic considerations of ODS.
Healthcare is a giant with feet of clay

Published: April 2016

Abstract
There is an increasing emphasis on using cost-effectiveness analysis to achieve a higher value for the money invested in the healthcare, avoiding waste and unnecessary costs. The process for achieving a better use of available resources should include five steps: collecting data, developing indicators, evaluating evidence, making informed decisions, and considering consequences. Clinical laboratories represent a paradigmatic model to improve data collection in order to develop further steps of the improvement process. Here we describe the experience of the “e-Valuate” project, aiming to improve the collection of laboratory data to provide useful information that should be the foundation for all other steps of this improvement project.
The role of computers to understand the past. The case of archaeological research
Authors: Barceló Juan A. 
Published: April 2016

Abstract
As practitioners of an historical discipline, archaeologists are in general, interested in guessing how ancient objects, buildings
and/or landscapes were produced and used in the past from the object's visual appearance and material properties. In the pursuit of
this general goal, archaeologists act as detectives looking for material cues (mostly visual) that may allow the discovering of social
actions that may have happened in the past. This investigation can be made intuitively, but also formally, in which case we need
computational tools and techniques to 1) extract necessary information from visual and non-visual data, 2) data processing to evaluate
relevant relationships between different items at different spatial and temporal scales, 3) build appropriate models that can be used
to provide explanatory hypothesis about the human past. In this paper I review the nature of archaeological problems and suggest
computational techniques and methods that can be useful in solving these kinds of questions. Emphasis is made on modern classification
and clustering techniques (neural networks, for instance), and computational simulation approaches.
Made in the humanities: Dual integral invariants for efficient edge detection
Authors: Mara Hubert 
Published: April 2016

Abstract
Motivated by the demand for robust character extraction from ancient documents with Script in 3D like cuneiform tablets, we
are developing curvature based filter algorithms using integral invariants. While previous work was focused on analyzing 3D-models
i. e. irregular triangular meshs in ℝ3, we introduce a fast, efficient adaption for edge detection in raster images. It
is an alternative to the Canny edge detector algorithm and other complex algorithms using first and second order derivative filters.
Our approach consists of two steps using (i) zero-crossings of volume integral invariants and (ii) surface integral invariants to
discard false positives introduced by noise. The runtime of these Dual Integral Invariants (DII) is comparable with Difference of
Gaussian filtering and it is independent of the number and length of edges. An additional benefit is the constant execution time as
line tracing is not necessary. As the proposed algorithm has no smoothing included it preserves smaller features than recent variants
of the Canny edge detector. We use artificial data sets with and without a known amount of noise to validate the accuracy of our
method in comparison with operators supplied by the OpenCV library. The equidistant spacing of raster images allows fast estimation of
the integral invariants based on filter masks like Roberts, Scharr and Kirsch. We show the results on well-known standard test images
and synthetic data.
Decentralized communication against surveillance and privacy violation
Authors: Graffi Kalman 
Published: April 2016

Abstract
The Internet is one of the main communication platforms of our society. In many countries,
communication contents and patterns are surveilled aiming to identify, punish or block
undesired ideas. I focus with my research on fully decentralized and secure communication
platforms which cannot be surveilled or switched off, on Android-based wireless mesh
networks which support local communication that do not pass through the Internet, as well as
on concepts for Internet-based democracy. My contributions aim for a practical usability in
form of prototypes and software provided to potential users.
Effects of Constitutive Properties on Pressure and Extent of Reaction
Authors: Arato Elisabetta , Morro Angelo 
Published: April 2016

Abstract
The paper applies the theory of mixtures to the chemical reaction rate. Concerning the time dependence of pressure, it is
shown that pressure increases, is constant or decreases depending on the analogous behaviour of mole numbers. The results
are established analytically and then numerically for the ideal gas, the van der Waals and the truncated virial
equations. Next, in connection with the ideal gas model, Denbigh assumption is established by starting from the
thermodynamic relation between (partial) pressure and Helmholtz free energy. Moreover, it is pointed out that the chemical
potential does not exactly equal the partial derivative of the Gibbs free energy with respect to the corresponding mole
number. This in turn is shown to imply that the evolution of a reaction is provided by the chemical potentials rather than
by the derivative of the Gibbs free energy. Subject to the assumption of ideal gas for the constituents, as
a thermodynamic requirement it is shown that if the number of moles increases the reaction is favoured by low pressures,
and viceversa, and explicit estimates are established.
Inverse Calibration Free fs-LIBS of Copper-Based Alloys

Published: April 2016

Abstract
In this work the analysis by Laser Induced Breakdown Spectroscopy (LIBS) technique of copper-based alloys having different
composition and performed with fs laser pulses is presented. A Nd:Glass laser (Twinkle Light Conversion,
λ = 527 nm at 250 fs) and a set of bronze and brass certified standards were used. The
inverse Calibration-Free method (inverse CF-LIBS) was applied for estimating the temperature of the fs laser
induced plasma in order to achieve quantitative elemental analysis of such materials. This approach strengthens the
hypothesis that, through the assessment of the plasma temperature occurring in fs-LIBS, straightforward and reliable
analytical data can be provided. With this aim the capability of the here adopted inverse CF-LIBS method, which is based
on the fulfilment of the Local Thermodynamic Equilibrium (LTE) condition, for an indirect determination of the species
excitation temperature, is shown. It is reported that the estimated temperatures occurring during the process provide
a good figure of merit between the certified and the experimentally determined composition of the bronze and brass
materials, here employed, although further correction procedure, like the use of calibration curves, can be demanded. The
reported results demonstrate that the inverse CF-LIBS method can be applied when fs laser pulses are used even
though the plasma properties could be affected by the matrix effects restricting its full employment to unknown samples
provided that a certified standard having similar composition is available.
The Effect of the Gravity Loading Countermeasure Skinsuit Upon Movement and Strength

Abstract
Carvil, PA, Attias, J, Evetts, SN, Waldie, JM, and Green, DA. The effect of the gravity loading countermeasure skinsuit upon movement and strength. J Strength Cond Res 31(1): 154–161, 2017—Effective countermeasures against musculoskeletal deconditioning induced by microgravity and disuse are required. A simple alternative to provision of artificial gravity by centrifugation is compressive axial loading. The Russian “Pingvin” suit was the first wearable suit to apply this concept using bungee cords tethered around the shoulders and feet. However, poor loading characteristics and severe thermal and movement discomfort were reported. The gravity loading countermeasure skinsuit (GLCS) uses a bidirectional weave to generate staged axial loading from shoulders to feet, better mimicking how Earth's gravity induces progressive loading head to foot. The Mk III GLCS's loading was evaluated and tolerability assessed during maximal joint motion, ambulation, and selected strength exercises. Eight subjects (5 male and 3 female; 28 ± 3 years; 179 ± 0.1 cm and 74.8 ± 2.9 kg), having given written informed consent, had an Mk III GLCS individually tailored. Axial loading imparted, body height, joint range of motion (ROM), ambulation, and strength tests (12 repetition maximum) were performed in the GLCS and gym attire, with subjective (rating of perceived exertion, thermal comfort, movement discomfort and body control) ratings recorded throughout. Gravity loading countermeasure skinsuit provided significant axial loading when standing but significantly reduced knee (−13°), spinal (−28°) and shoulder flexion/extension ROM (−34°/−13°), in addition to Sit and Reach (−12.8 cm). No thermal issues were reported but there was an increase in subjective discomfort. Gravity loading countermeasure skinsuit did not significantly impede strength exercise, with the exception of shoulder press. The GLCS (Mk III) demonstrates potential as a countermeasure by providing tolerable, static axial loading. Furthermore, it may serve as an elasticlike strength exercise adjunct, which may have utility as a rehabilitation modality after further design refinement.

Abstract
Cornell, DJ, Paxson, JL, Caplinger, RA, Seligman, JR, Davis, NA, Flees, RJ, and Ebersole, KT. In-game heart rate responses among professional baseball starting pitchers. J Strength Cond Res 31(1): 24–29, 2017—The purpose of the current study was to characterize the in-game heart rate (HR) responses of baseball pitching. In-game HR was recorded from 16 professional baseball starting pitchers (mean ± SD, age = 22.1 ± 1.3 years; height = 187.9 ± 4.4 cm; weight = 90.5 ± 9.5 kg) for a total of 682 innings (home = 381, away = 301). All analyzed HR data were then normalized to each pitcher's age-predicted maximal HR (%HRmax). The group mean ± SD in-game %HRmax among all pitchers was 84.8 ± 3.9%, suggesting that baseball pitching is predominantly an anaerobic task. A split-plot mixed-model repeated measures analysis of variance identified a significant interaction effect between inning and game location (p = 0.042). Follow-up simple effects indicated that the in-game %HRmax was significantly different across innings, but only during home starts (p < 0.001). Specifically, pairwise analyses indicated that the in-game %HRmax during home starts were significantly (p ≤ 0.05) higher in the first and second innings than in all other innings. In addition, follow-up simple effects indicated that the in-game %HRmax was significantly (p = 0.017) higher during home starts than away starts in the first inning (87.3 ± 3.6% vs. 85.8 vs. 3.8%, respectively). Thus, it is possible that inning-dependent psychological factors may have contributed to the observed changes in in-game physiological intensity across innings and that these factors are specific to game location. Consequently, strength and conditioning practitioners should prescribe high-intensity exercises when developing conditioning programs for professional baseball starting pitchers.

Abstract
Costa, VP, Guglielmo, LGA, and Paton, CD. Validity and reliability of the PowerCal device for estimating power output during cycling time trials. J Strength Cond Res 31(1): 227–232, 2017—This study assessed the validity and reproducibility of the PowerCal device for estimating power output (PO) during cycling hilly time trials (TTs). Twenty-one well-trained men cyclists performed an incremental exercise test and three 20-km TTs (34.1 ± 10.6 years; 73.2 ± 3.2 kg, 176.8 ± 6.2 cm; maximal PO, 334 ± 31 W; maximal oxygen uptake, 61.0 ± 4.2 ml·kg−1·min−1). The first TT was used for familiarization, and the tests were separated by at least 72 hours. Mean PO over the 20-km TT was significantly greater for the Velotron (282 ± 27 W) than for the PowerCal (242 ± 28 W). The mean power over each kilometer of the trial ranged from 5.8 to 23.4% greater on the Velotron than on the PowerCal. High within-subject variation between the trials was substantially greater for the PowerCal (4.9%) than for the Velotron (1.8%). High coefficients of variation scores for the Velotron test-retest were found to be concentrated in the beginning and final meters of the TT (∼6.0%), whereas the scores were lower in the middle of the trials (∼3.0%). In contrast, the PowerCal test-retest achieved a high coefficient of variation (∼6.0%) in each km over the TT. Thus, the PowerCal device should be used with caution during cycling activities because it is not reliable and underestimates PO.
