Functional Communication Training in Rett Syndrome: A Preliminary Study
Authors: Byiers Breanne J. , Dimian Adele , Symons Frank J. 
Published: July 2014

Abstract
Rett syndrome (RTT) is associated with a range of serious neurodevelopmental consequences including severe communicative impairments. Currently, no evidence-based communication interventions exist for the population (Sigafoos et al., 2009). The purpose of the current study was to examine the effectiveness of functional assessment (FA) and functional communication training (FCT) methods for teaching 3 individuals (ages 15–47 years) with classic RTT novel communicative behaviors. Using single-case experimental designs, functional reinforcers were identified (FA) and each participant quickly learned to activate a voice-output switch to obtain a reinforcer (FCT). These results suggest that individuals with classic RTT can learn novel communicative responses, which has important implications for future intervention research.
On the existence of nilsolitons on 2-step nilpotent Lie groups
Authors: Oscari D. 
Published: July 2014

Abstract
A 2-step nilpotent Lie algebra n is said to be of type (p, q) if dim n = p + q and dim[n, n] = p. By considering a class of 2-step nilpotent Lie algebras naturally attached to graphs, we prove that there exist indecomposable, 2-step nilpotent Lie groups of type (p, q) which do not admit a nilsoliton metric for every pair (p, q) such that 21 ≤ q and q − 1 ≤ p ≤½ q2 − 5/2q + 9. This improves a result due to Jablonski [6].
On the algebraic models of symmetric smooth manifolds
Authors: Ghiloni R. , Tancredi A. 
Published: July 2014

Abstract
Let M be a compact smooth submanifold of ℝn that is symmetric with respect to an affine subspace L. In this paper, we prove that M has a symmetric Nash model N, which is unique up to Nash isomorphism preserving symmetries. Such a model N can be chosen to be a union of nonsingular connected components of a real algebraic set if M is a (not necessarily compact) Nash submanifold of ℝn. If M does not intersect the mirror L, then we are able to construct a symmetric algebraic model of M too. More precisely, in this case, we show that the set of birationally nonisomorphic symmetric algebraic models of M has the power of continuum.
Rotational linear Weingarten hypersurfaces in the Euclidean sphere Sn+1
Authors: Barros A. , Silva J. , Sousa P. 
Published: July 2014

Abstract
We present a complete description of all rotational linear Weingarten hypersurfaces in the Euclidean sphere Sn+1. These hypersurfaces are characterized by a linear relation aH1+bH2 = c, where H1 and H2 stand for the first two symmetric functions of the principal curvature and a, b and c are real constants.
On axiomatic definitions of non-discrete affine buildings
Authors: Bennett C. D. , Schwer P. N. , Struyve K. 
Published: July 2014

Abstract
We prove the equivalence of several sets of axioms for non-discrete affine buildings, by providing different types of metric, exchange and atlas conditions. We apply our result to show that the definition of a Euclidean building depends only on the topological equivalence class of the metric on the model space. The sharpness of the axioms dealing with metric conditions is illustrated in an appendix. There it is shown that a space X defined over a model space with metric d is possibly a building only if the induced distance function on X satisfies the triangle inequality.
On the representation theory of partition (easy) quantum groups
Authors: Freslon Amaury , Weber Moritz 
Published: July 2014

Abstract
Compact matrix quantum groups are strongly determined by their intertwiner spaces, due to a result by S. L. Woronowicz. In the case of easy quantum groups (also called partition quantum groups), the intertwiner spaces are given by the combinatorics of partitions, see the initial work of T. Banica and R. Speicher. The philosophy is that all quantum algebraic properties of these objects should be visible in their combinatorial data.
We show that this is the case for their fusion rules (i.e. for their representation theory). As a byproduct, we obtain a unified approach to the fusion rules of the quantum permutation group

${S_{N}^{+}}$

, the free orthogonal quantum group

${O_{N}^{+}}$

as well as the hyperoctahedral quantum group

We then extend our work to unitary easy quantum groups and link it with a “freeness conjecture” of T. Banica and R. Vergnioux.
Dirac cohomology and geometric quantization
Authors: Chuah Meng-Kiat , Huang Jing-Song 
Published: July 2014

AbstractLetGbe a connected real semisimple Lie group having a finite center and a compact Cartan subgroupTwith Lie algebra𝔱0${\mathfrak{t}_{0}}$. Let ω be aG×T${G\times T}$-invariant symplectic form onX=G×𝔱0${X=G\times\mathfrak{t}_{0}}$. We incorporate Dirac cohomology into the geometric quantization of(X,ω)${(X,\omega)}$and study the resulting multiplicity-free unitaryG×T${G\times T}$-representation on a Hilbert spaceℋ⁢(X,ω)${\mathcal{H}(X,\omega)}$. We also perform symplectic reduction of(X,ω)${(X,\omega)}$and show that our quantization method satisfies the principle “quantization commutes with reduction”. As an application we construct various models of discrete series.
On the direct products of quasi-finitely axiomatizable groups
Authors: Lasserre Clément 
Published: July 2014

Abstract
The notions of quasi-finitely axiomatizable (QFA) groups and quasi-axiomatizable (QA) groups were introduced by A. Nies in 2003. We say that a finitely generated group G is QFA if there exists a first-order sentence ϕ that is satisfied by G such that each finitely generated group that satisfies ϕ is isomorphic to G. The aim of this paper is to further investigate properties of direct products with respect to these notions, thereby extending F. Oger's result for nilpotent-by-finite groups. More precisely, we study the relations between (1) G and H are QFA, and (2) G×H is QFA. We prove that (1) implies (2) under the additional condition that there exist bounds on the commutator width in the central extensions of the center Z(H) by G and Z(G) by H. We also prove that the converse is true if the groups are ℤ-replaceable, in particular if they are residually
soluble. Thus (1) and (2) are equivalent, for instance, in the classes of finitely generated abelian-by-polycyclic or abelian-by-metanilpotent groups.
Investigation of elemental and radiological contamination of soils in two shipyards in Chittagong, Bangladesh

Published: July 2014

Abstract
An analysis of metallic
elements and natural radioactivity in soils collected from two
shipyards and their surroundings in Chittagong, Bangladesh is
presented. The elemental concentrations of the metals Cr, Mn, Fe, Ni
and Cu were obtained by PIXE analysis with a 3 MV Tandem
Accelerator, and the radioactivity of 226Ra,
232Th and 40K was determined using HPGe
gamma-ray spectrometry. From the mean specific activities of the three
radionuclides in soil samples, the radium equivalent activity, the
gamma absorbed dose rate, the annual effective dose rate and the
external hazard index were calculated. The study was focused on
investigation of soil contamination via shipbreaking
activities, if any. The somewhat higher contents of Cr, Mn, Fe, Ni and
Cu in soil samples of shipyards, as compared to other locations, seem
to be caused by the shipbreaking activities. The specific
radioactivities as well as radium equivalent activity in soils of
shipyards are also higher and thus possibly an indirect result of
shipbreaking activities.

Published: July 2014

Zusammenfassung
Bei der Fertigung von organischen LEDs (OLEDs) werden einzelne Schichten mit
geschalteten Effusionszellen aufgedampft. Die zu messenden Raten liegen im
Bereich der minimalen Auflösung des Messsystems. Aufgrund der hohen
Empfindlichkeit treten viele Messausreißer und ein großes Rauschen
auf. Herkömmliche systemtheoretisch beschreibbare Filter stoßen hier
an ihre Grenzen. Eine große Zeitkonstante glättet zwar das Signal,
jedoch auf Kosten der Dynamik. Das hier vorgeschlagene statistische Filter
erkennt Messausreißer und glättet den Signalverlauf, ohne
wesentliche Informationen an den Schaltflanken zu verlieren.

ObjectiveCushing's syndrome (CS) is associated with neuropsychological deficits. As the cerebellum plays a key role in neuropsychological functions it may be affected in CS. The aim of this study was to investigate whether patients with CS have a smaller cerebellar volume than healthy controls, and to analyse whether cerebellar volume is associated with neuropsychological performance and clinical parameters.DesignA cross-sectional study was performed.MethodsThirty-six CS patients (15 with active CS and 21 with CS in remission) and 36 controls matched for age, sex, and education underwent neuropsychological testing, quality of life assessment, clinical evaluation, and magnetic resonance imaging brain scan. Cerebellar volumes (white matter and cortex, bilateral) were calculated using FreeSurfer Software.ResultsPatients with active CS showed smaller bilateral cerebellar cortex volumes than controls (left,P=0.035 and right,P=0.034), as well as a trend toward smaller right cerebellar cortex volumes than patients in remission CS (P=0.051). No differences were observed in the volume of cerebellar white matter between the three groups. Both right and left cerebellar cortex volumes correlated negatively with triglyceride levels (right:r=−0.358,P=0.002 and left:r=−0.317,P=0.005) and age at diagnosis (right:r=−0.433,P=0.008 and left:r=−0.457,P=0.005). Left cerebellar cortex volume also correlated positively with visual memory performance (r=0.245,P=0.038). Right cerebellar cortex volume positively correlated with quality-of-life scores (r=0.468,P=0.004).ConclusionsThe cerebellar cortex volume is smaller in active CS patients than in controls. This finding is associated with poor visual memory and quality of life and is mostly pronounced in patients with higher triglyceride levels and older age at diagnosis.

Authors: Matthews Jennifer L.K. , Oddone-Paolucci Elizabeth , Harrop Robertston A. 
Published: July 2014

Objective To examine the birth prevalence, gender distribution, and pattern of surgical intervention for clefts in Canada (1998 to 2007). Also to highlight the difficulties associated with studying the epidemiology of clefts using the current data collection mechanisms. Methods Epidemiologic data acquired from the Canadian Institute for Health Information. Setting Population-based study in Canada 1998 to 2007. Patients All live births with an International Classification of Diseases (9th or 10th revision) diagnostic code for cleft palate or for cleft lip with or without cleft palate or with a surgical intervention code for repair of cleft lip or cleft palate. Main Outcome Measures Birth prevalence, gender distribution, and pattern of surgical intervention. Results There were 3,015,325 live births in Canada (1998 to 2007). The mean birth prevalence was 0.82 per 1000 live births for cleft lip with or without cleft palate and 0.58 per 1000 live births for cleft palate. The birth prevalence of cleft lip with or without cleft palate was significantly higher in boys, with a stable boy to girl ratio of 1.75:1. Cleft palate was significantly greater in girls; however, the boy to girl ratio decreased from 0.97:1 in 1998 to 0.59:1 in 2007. The median age of repair in Canada from 1998 to 2007 was 4.7 months for cleft lip and 11.6 months for cleft palate. Thirty percent of patients underwent cleft palate repair after age 1. Conclusion The birth prevalence of cleft palate and cleft lip with or without cleft palate is stable in Canada. An increasing birth prevalence of cleft palate in girls is suggested. The timing of surgical intervention is consistent with current standards. The challenges associated with collecting these data in Canada are discussed.
Extreme High-Pressure and/or High-Temperature Wireline-Data Acquisition: Planning for Success
Authors: Owens J.. , Parry G.. , Taylor B.. 
Published: July 2014

Summary
Data acquisition in extreme environments of high pressure and/or high temperature (HPHT) with pressures up to 30,000 psi and temperatures up to 500°F requires not only specialist technology capable of surviving these conditions but also many months of preparation and planning to ensure a successful operation.
The aim of this publication is to provide an overview of what is involved in the planning, preparation, and execution of an extreme HPHT wireline data acquisition—from the customer setting the information objectives through to data delivery. This includes developing an agreed quality plan between the data provider and the customer covering testing and deployment of the latest extreme HPHT logging equipment.
One must consider all aspects to minimize risks including detailed tailoring of the logging programs to manage time in hole, to ensure accurate depth control, and, by using a deployment risk-management process, to ensure that what goes in the hole comes out again.
The implementation of these procedures is illustrated with a case history of a series of HPHT exploration wells drilled in the Central Graben of the North Sea (the "HPHT Heartland" of the North Sea). Bottomhole conditions were predicted to approach 400°F and 15,000 psi. These extreme conditions negated the use of conventional wireline tools, and so, from initial early planning discussions between client and service provider, new detailed programs were designed and implemented as a specific "Quality Plan" to use the advanced HPHT wireline-logging tools.
Changes in Oxygen Conditions in Pławniowice Reservoir as a Result of Restoration with Hypolimnetic Withdrawal Method
Authors: Kostecki Maciej 
Published: July 2014

Abstract
The restoration of the anthropogenic Pławniowice water reservoir with the hypolimnion withdrawal method (the Olszewski's tube) began in December 2003. The decision to restore the reservoir had been taken due to its terrible condition resulting from the hypertrophy, which had been indicated by the research from the years 1993–1998.
The following paper presents the results of eight-year-long research into the formation of oxygen conditions and restoration settings. They were compared with the data obtained from the research before the restoration. Positive changes were witnessed. It was showed that grasping the changes in oxygen conditions enables the comparison of oxygen profiles in the same months in subsequent years. The ratio of anoxic water layer thickness to the oxygenated layer thickness was suggested as a factor characterizing oxygen conditions. The area described with an izooxa in the xy coordinate system was suggested as a factor [O2 mg/m2] allowing researchers to understand and describe occurring changes. It was observed that the oxygen solved in water as a result of the restoration occurred in the whole water column in the third decade of July. The oxygen concentration in the hypolimnion gradually rose in May, June and July each year. It was showed that the improvement in oxygen conditions stemmed from progressing oligotrophy of the reservoir.

Dy rektywalna teoria znaczenia jako teoria znaczenia wąskiego
Authors: Grabarczyk Paweł 
Published: July 2014

StreszczenieW artykule przedstawiam zalety traktowania dyrektywalnej teorii znaczenia (DTZ) jako wspólcześnie rozumianej teorii znaczenia wąskiego. Rozpoczynam od sformułowania siedmiu postulatów, które udana teoria znaczenia wąskiego powinna spełniać. Następnie kontrastuję teorię dyrektywalną z semantyką ról pojeciowych Neda Blocka. Dwa aspekty tej teorii zostają włczone do DTZ - jej naturalizm i dodatkowy, czwarty typ dyrektyw znaczeniowych. W dalszej części artykułu pokazuję jak skorzystanie z DTZ w charakterze teorii znaczenia wąskiego pozwala na uniknięcie pewnych dobrze znanych wad semantyk funkcjonalnych. Na zakończenie pokazuję w jaki sposób zmodyfikowana DTZ spełnia siedem postulatów, od których rozpoczajem, i zarysowuję krótko dalsze drogi rozwoju dla tej teorii.
Renowacja radykalnego konwencjonalizmu
Authors: Grobler Adam 
Published: July 2014

StreszczenieArtykuł identyfikuje motywy wspólczesnej filozofii antycypowane przez rady-kalny konwencjonalizm. Zarazem wskazuje na to, że z uwagi na odkrycie ute-oretyzowania obserwacji radykalny konwencjonalizm jest dziś stanowiskiem przestarzałym. Ta diagnoza służy poszukiwaniu takiej rewizji radykalnego konwencjonalizmu, która nadaje się do utrzymania i zachowuje jak najwiócej elementów oryginalnego stanowiska Ajdukiewicza. Analizując m.in. stosunek Quine'a doktryny niezdeterminowania przekładu i Wittgensteina koncepcji gier językowych do radykalnego konwencjonalizmu, autor dochodzi do wniosku, że radykalny konwencjonalizm należy uzupełnić o pragmatyczną teorię obserwacji Feyerabenda, zaś oryginalne stanowisko można potraktować jako idealiza-cyjną teorię języka. Innym wnioskiem jest, że opanowanie jakiejkolwiek apa-ratury pojęciowej wymaga znajomości alternatywnych aparatur pojeciowych.

Rekonstrukcja opiera się częściowo na dwóch nieznanych tekstach Kazimierza Ajdukiewicza, odnalezionych ostatnio w jednym z dzienników lwowskich tego okresu.
Czy Ajdukiewicz był realistą?
Authors: Leszczyński Damian 
Published: July 2014

StreszczenieWedług standardowej wykładni Ajdukiewicz był realistę a jedną z jego naj-ważniejszych zasług było sformułowanie celnych argumentów przeciwko ide-alizmowi. Taką interpretację znajdujemy zarówno w popularnych opracowa-niach, jak i specjalistycznych badaniach poświeconych jego filozofii. Jednak bliższe przyjrzenie się jego pogłdom, zarówno w wersji wczesnej (radykalny konwencjonalizm), jak i późnej (radykalny empiryzm), stawia pod znakiem zapytania to standardowe ujęcie. Jeśli bowiem mamy Ajdukiewicza nazywać realistę to o jaki właściwie typ realizmu może tu chodzić? Moja hipoteza głosi, że „realizm” Ajdukiewicza niewiele ma wspólnego z tym, co tradycyjnie rozumie się pod tym pojęciem. Świadczą o tym glówne założenia jego filozofii: (a) akceptacja stanowiska Kanta o decydującej roli podmiotowych struktur poznawczych w kształtowaniu obrazu świata, (b) semantyczna interpretacja tego stanowiska (w duchu pierwszej filozofii Wittgensteina, którą za Steniusem można określić jako lingwistyczny transcendentalizm), (c) przyjęcie konwen-cjonalistycznej tezy o pluralizmie struktur (schematów pojeciowych) i obrazów świata; w pózniejszym okresie doszło jeszcze założenie (d) uprzywilejowujące schemat pojeciowy języka potocznego oraz języka nauk empirycznych.
