Verification of Temporal Properties of Concurrent Systems
Authors: Andersen Henrik Reif
Published: February 2016

This thesis is concerned with the verification of concurrent systems modelled by process algebras. It provides methods and techniques for reasoning about temporal properties as described by assertions from an expressive modal logic -- the modal µ-calculus. It describes a compositional approach to model checking, efficient local and global algorithms for model checking finite-state systems, a general local fixed-point finding algorithm, a proof system for model checking infinite-state systems, a categorical completeness result for an intuitionistic version of the modal µ-calculus, and finally it shows some novel applications of the logic for expressing behavioural relations.
Strictness Types: An Inference Algorithm and an Application
Authors: Amtoft Torben
Published: February 2016

This report deals with  strictness types, a way of recording whether a function needs its argument(s) or not. We shall present an inference system for assigning strictness types to expressions and subsequently we transform this system into an algorithm capable of annotating expressions with strictness types. We give an example of a transformation which can be optimized by means of these annotations, and finally we prove the correctness of the optimized transformation -- at the same time proving the correctness of the annotation.

Everything has been implemented; documentation can be found in appendix.

Authors: Bødker Susanne
Published: February 2016

This paper describes work on the AT project. (''AT'' stands for ''Arbejdstilsynet'', the Danish national labor inspection service.) The AT project is a collaboration between AT-Aarhus and Aarhus University (AU).

 

Participating in the project from the Aarhus branch of the AT are 40-50 people from a variety of occupations including secretaries, administrative workers, machinists, engineers, lawyers, and therapists. The researchers on the project are all connected in some way to Aarhus University and include the authors.

 

The paper provides an overview of the project through descriptions of its various activities. For more thorough analyses of project activities, the reader is referred to the bibliography. The paper ends with preliminary discussions of the present state of the project and our long-term outlook.
Determinizing Asynchronous Automata
Authors: Klarlund Nils , Mukund Madhavan , Sohoni Milind
Published: February 2016

A concurrent version of a finite-state automaton is a set of processes that cooperate in processing letters of the input. Each letter read prompts some of the processes to synchronize and decide on a joint move according to a non-deterministic transition relation. Such automata are known as asynchronous automata.
 

The question whether these automata can be determinized while retaining the synchronization structure has already been answered is the positive, but indirectly, by Zielonka's Theorem. Unfortunately, this construction does not give an optimal solution.

 

In this paper we present an elementary proof, which generalizes the classic subset construction for finite-state automata. The proof uses in an essential way an earlier finite-state construction by Mukund and Sohoni for maintaining each process's latest knowledge about other processes.

 

Our construction is only double-exponential and thus is the first essentially to match the lower bound.

 

In conjunction with earlier results of Ochmanski and Pighizzini, our construction provides a new (and in a sense ''classical'') proof of Zielonka's theorem that every recognizable trace language is accepted by a deterministic asynchronous automaton whose structure precisely captures the independence relation of the given trace alphabet.

Performance Measurement at Universities: Studying Function and Effect of Student Evaluations of Teaching
Authors: Lueg Klarissa
Published: February 2016

This paper proposes empirical approaches to testing the reliability, validity, and organizational effectiveness of student evaluations of teaching (SET) as a performance measurement instrument in knowledge management at the institutional level of universities. Departing from Weber’s concept of bureaucracy and critical responses to this concept, we discuss how contemporary SET are used as an instrument of organizational control at Danish universities. A discussion of the current state of performance measurement within the frame of new public management (NPM) and its impact on knowledge creation and legitimation forms the basis for proposing four steps of investigation. The suggested mixed-methods approach comprises the following: first, thematic analysis can serve as a tool to evaluate the legitimacy discourse as initiated by official SET affirmative documents by government, university, and students. Second, constructs for the SET questionnaire can be developed and compared to existing SET questionnaires in terms of reliability and validity. Third, data from SET can be used to corroborate the relationship between the qualitative (comments) and quantitative (scaled questionnaire) sections. Fourth, it can be investigated if SET actually contribute to teaching improvement by examining how the instrument is integrated into systematic ex-ante and ex-post organizational management. It is expected to find discrepancy between the proponents’ intent to evaluate teaching and the way the performance measurement instrument is implemented. 
First record of the zoophytophagous plant bug Atractotomus mali (Hemiptera: Miridae) in Quebec orchards
Authors: Saguez Julien , Lasnier Jacques , Schwartz Michael D. , Vincent Charles
Published: February 2016

Atractotomus mali(Meyer-Dür, 1843) (Hemiptera: Miridae) is a zoophytophagous insect associated with orchards in Europe and North America. In Canada, it has previously been reported in apple (Malus domesticaBorkh) orchards in several provinces, but mainly in Nova Scotia, where it induced more damage on fruit than predatory effects. During the summer of 2014, we collected 33 specimens in an apple orchard in Magog (QC, Canada), using a tapping method. This study constitutes the first record ofA. maliin Quebec.
Registered report: The common feature of leukemia-associated IDH1 and IDH2 mutations is a neomorphic enzyme activity converting alpha-ketoglutarate to 2-hydroxyglutarate
Authors: Fiehn Oliver , Showalter Megan Reed , Schaner-Tooley Christine E ,   Reproducibility Project: Cancer Biology
Published: February 2016

The Reproducibility Project: Cancer Biology seeks to address growing concerns about reproducibility in scientific research by conducting replications of selected experiments from a number of high-profile papers in the field of cancer biology. The papers, which were published between 2010 and 2012, were selected on the basis of citations and Altmetric scores (Errington et al., 2014). This Registered Report describes the proposed replication plan of key experiments from “The common feature of leukemia-associated IDH1 and IDH2 mutations is a neomorphic enzyme activity converting alpha-ketoglutarate to 2-hydroxyglutarate” by Ward and colleagues, published in Cancer Cell in 2010 (Ward et al., 2010). The experiments that will be replicated are those reported in Figures 2, 3 and 5. Ward and colleagues demonstrate the mutations in isocitrate dehydrogenase 2 (IDH2), commonly found in acute myeloid leukemia (AML), abrogate the enzyme’s wild-type activity and confer to the mutant neomorphic activity that produces the oncometabolite 2-hydroxyglutarate (2-HG) (Figures 2 and 3). They then show that elevated levels of 2-HG are correlated with mutations in IDH1 and IDH2 in AML patient samples (Figure 5). The Reproducibility Project: Cancer Biology is a collaboration between the Center for Open Science and Science Exchange and the results of the replications will be published by eLife.
Effect of atomic modulation on the J-mixing-dominant magnetic anisotropy in SmFe7 epitaxial films
Authors: Kusumori Takeshi , Fujita Asaya , Mibu Ko
Published: February 2016

The magnetocrystalline anisotropy in TbCu7-type SmFe7 epitaxial films has been verified in relation to the 4f-electron character. The reinforcement of the 4f intermultiplet mixing by nitrogenation is verified from an enlarged basal-plane anisotropy. The sign of the uniaxial anisotropy constant is varied from positive to negative by nitrogenation, in contradiction to behaviors in Th2Zn17-type Sm2Fe17N
x
. 57Fe Mössbauer spectroscopy and first-principles calculation revealed that the transformation of the Sm-neighboring Fe-atom plane from a rippling to a flat shape, which characterizes the Th2Zn17- and TbCu7-type local structures, markedly modulates the magnetic anisotropy, owing to the 4f semilocalized character.

N-face GaN

films with hillock-free smooth surfaces grown by group-III-source flow-rate modulation epitaxy
Authors: Lin Chia-Hung , Akasaka Tetsuya , Yamamoto Hideki
Published: February 2016

N-face GaN

films were grown by group-III-source flow-rate modulation epitaxy (FME), wherein the flow-rate of group-III sources are sequentially modulated under a constant supply of NH3. By using GaN bulk substrates with a low misscut angle (∼0.3°), hillock-free N-face GaN

surfaces are achieved over almost the whole sample area (10 × 5 mm2). A smooth surface with the root mean square roughness of 0.39 nm exhibits the step-and-terrace structure. Group-III-source FME also reduces carbon impurities in the films, resulting in weakened blue and yellow deep emissions in the photoluminescence spectrum.
Quasi-ballistic transport model for top- and back-gated graphene nanoribbon field-effect transistors
Authors: Hu Shuyan , Hu Guangxi , Wang Lingli , Liu Ran , Zheng Lirong
Published: February 2016

A carrier transport model for graphene nanoribbon field-effect transistors (GNR FETs) is obtained using McKelvey’s flux and quasi-ballistic transport theories. Source/drain series resistances are taken into account. With the model, an analytical expression for drain-to-source current is achieved including only three fitting parameters. The model is verified by simulation, and good agreements are observed. With the model, the drain-to-source current characteristics of GNR FETs with different drain or gate biases can be obtained very swiftly, saving much simulation time. The model will provide some design insights into the practical use of GNR FETs.

E
of a water molecule encapsulated in fullerene isomers from C60 to C80, all of which satisfy the isolated pentagon rule. Our calculations show that the dipole energy exhibits unusual features not expected for an isolated water molecule in vacuum. The dipole energy depends sensitively on the electronic structure of fullerenes and their cage network topology when situated in an external electric field. We also demonstrate that the electrostatic potential inside the fullerene exhibits an anisotropic feature with respect to the applied field.

Authors: Illarionov Yury Yu. , Waltl Michael , Smith Anderson D. , Vaziri Sam , Ostling Mikael , Lemme Max C. , Grasser Tibor
Published: February 2016

We study the positive and negative bias-temperature instabilities (PBTI and NBTI) on the back gate of single-layer double-gated graphene field-effect transistors (GFETs). By analyzing the resulting degradation at different stress times and oxide fields we show that there is a significant asymmetry between PBTI and NBTI with respect to their dependences on these parameters. Finally, we compare the results obtained on the high-k top gate and SiO2 back gate of the same device and show that SiO2 gate is more stable with respect to BTI.
Determination of recombination coefficients in InGaN quantum-well light-emitting diodes by small-signal time-resolved photoluminescence
Authors: Nippert Felix , Karpov Sergey , Pietzonka Ines , Galler Bastian , Wilm Alexander , Kure Thomas , Nenstiel Christian , Callsen Gordon , Straßburg Martin , Lugauer Hans-Jürgen , Hoffmann Axel
Published: February 2016

We suggest a novel technique for the evaluation of the recombination coefficients corresponding to Shockley–Read–Hall, radiative, and Auger recombination that occur in InGaN/GaN-based light-emitting diodes (LEDs). This technique combines the measurement of the LED efficiency as a function of LED drive current with a small-signal time-resolved photoluminescence measurement of the differential carrier life time (DLT). Using the relationships between the efficiency and DLT following from the empirical ABC-model, one can evaluate all three recombination coefficients. The suggested technique is applied to a number of single- and multiple-quantum well LEDs to gain a deeper insight into the mechanisms ultimately limiting their efficiency.
tt in Old Khotanese
Authors: Hitch Doug
Published: February 2016

Orthographic tt in Old Khotanese has often been held as always representing single phonemic /t/. In the 1930s Ernst and Manu Leumann suggested that in four categories of words intervocalic tt represents double /tt/. Here I expand these four categories and analyze the position of these words within the metrical structure of The Book of Zambasta, showing that the Leumanns were half right and that in some cases tt=/tt/. In 1981 two theories were offered about the origin of the tt-device. Oskar von Hinüber’s suggestion that the device is derived from Middle Indic practice has perhaps been most generally accepted. R. E. Emmerick’s tentative suggestion that the device is an internal development, spread from words that he knew from meter contained tt=/tt/, has gained less traction. Both ideas are incorporated here. New analytical tools are used which are based on a study of the metrical system in The Book of Zambasta (Hitch 2014).

Correlation Between Cervical Lengths Measured by Transabdominal and Transvaginal Sonography for Predicting Preterm Birth
Authors: Cho Hyun Jin , Roh Hyun-Jin
Published: February 2016

Objectives

Cervical length assessment is important for predicting preterm birth. Cervical length measurement using transabdominal sonography is more comfortable for the patient but has more limitations than transvaginal sonography. Our aim was to determine whether transabdominal sonography could identify those women who should undergo transvaginal sonography for prediction of preterm birth.

Methods

In this prospective study, women underwent cervical length measurements by transabdominal and transvaginal sonography between 20 and 29 gestational weeks and were followed until delivery. We assessed whether short cervical lengths on transabdominal sonography could predict short cervical lengths on transvaginal sonography and whether these measurements could predict preterm births (<34 gestational weeks).

Results

The mean cervical lengths were not significantly different between the techniques (mean ± SD, 3.78 ± 0.82 and 3.82 ± 0.77 cm on transabdominal and transvaginal sonography, respectively; P = .09). The sensitivity of short cervical lengths (<2 cm) on transabdominal sonography for prediction of short cervical lengths on transvaginal sonography was 100%. The sensitivity, specificity, positive predictive value, negative predictive value, and relative risk of short cervical lengths (<2 cm) for predicting preterm birth were 21.4%, 98.68%, 50.00%, 95.32%, and 13.22 when using transabdominal sonography and 28.57%, 94.94%, 66.6%, 95.74%, and 17.78 when using transvaginal sonography, respectively. In an analysis that included cases with transabdominal sonography, the sensitivity of short cervical lengths for predicting preterm birth was increased.

Conclusions

Women whose cervical lengths are measurable and long on transabdominal sonography may not need transvaginal sonography. Women whose cervical lengths are unmeasurable or short (<2 or <2.5 cm) on transabdominal sonography should undergo transvaginal sonography to measure cervical lengths for prediction of preterm birth.
Spatiotemporal Image Correlation and Volumetric Impedance Indices in the Neonatal Brain
Authors: Schindler Tim , Gilbert Yasmin , Wu Linda , Oei Ju Lee , Welsh Alec
Published: February 2016

Objectives

Changes in tissue perfusion can be critically important in the vulnerable neonate, but they are very difficult to assess at the bedside. Spatiotemporal image correlation (STIC) sonography is an exciting concept that allows assessment of blood flow by rearranging and merging multiple 2‐dimensional color images to create serial 3‐dimensional images showing regional blood flow throughout the cardiac cycle. Variations in tissue blood flow may reflect tissue impedance and perfusion. The aim of this study was to demonstrate that it is possible to use STIC images to evaluate tissue impedance in the neonatal brain.

Methods

Spatiotemporal image correlation data sets were acquired by cranial sonography in 19 neonates. Offline data analysis was performed by using virtual organ computer‐aided analysis. With the use of STIC images from different phases of the cardiac cycle, impedance indices were calculated, based on maximum (systolic), minimum (diastolic), and mean virtual organ computer‐aided analysis values, in the same way that resistive indices are calculated in 2‐dimensional sonography.

Results

Volumetric indices for tissue impedance were obtained for all neonates. Intraclass correlation coefficients (95% confidence intervals) for volumetric impedance indices were as follows: systolic/diastolic ratio, 0.793 (0.615–0.906); pulsatility index, 0.790 (0.609–0.905); and resistive index, 0.783 (0.598–0.901). Interclass correlation coefficients for image processing and analysis were as follows: systolic/diastolic ratio, 0.868 (0.692–0.947); pulsatility index, 0.904 (0.772–0.962); and resistive index, 0.914 (0.794–0.966).

Conclusions

This study shows that STIC data sets can be used to calculate volumetric impedance indices in the neonatal brain. Preliminary assessment shows that this technique appears reliable and allows evaluation of regional tissue impedance in the neonate.
Prognostic Value of Fetal Thymus Size in Intrauterine Growth Restriction
Authors: Ekin Atalay , Gezer Cenk , Taner Cuneyt Eftal , Solmaz Ulas , Gezer Naciye Sinem , Ozeren Mehmet
Published: February 2016

Objectives

Our aim was to evaluate the size of the fetal thymus by sonography in pregnancies with intrauterine growth restriction (IUGR) and to search for a possible relationship between a small fetal thymus and adverse perinatal outcomes.

Methods

The transverse diameter of the fetal thymus was prospectively measured in 150 healthy and 143 IUGR fetuses between 24 and 40 weeks' gestation. The fetuses with IUGR were further divided according to normal or abnormal Doppler assessment of the umbilical and middle cerebral arteries and ductus venosus. Measurements were compared with reference ranges from controls. To determine which perinatal outcomes were independently associated with a small fetal thymus, a multivariate logistic regression analysis was performed.

Results

Thymus size was significantly lower in IUGR fetuses compared to controls (P < .05). Among IUGR fetuses, thymus size was significantly smaller in IUGR fetuses with abnormal Doppler flow compared to normal flow (P < .05). A small thymus in IUGR fetuses was independently associated with early delivery (odds ratio [OR], 1.24; 95% confidence interval [CI], 1.05–1.49; P= .023), respiratory distress syndrome (OR, 1.36; 95% CI, 1.09–1.78; P= .005), early neonatal sepsis (OR, 1.65; 95% CI, 1.11–2.42; P= .001), and a longer stay in the neonatal intensive care unit (OR, 1.33; 95% CI, 1.08–1.71; P = .017).

Conclusions

Intrauterine growth restriction is associated with fetal thymic involution, and a small fetal thymus is an early indicator of adverse perinatal outcomes in pregnancies complicated by IUGR.
Sequent Occupance
Authors: Mathewson Kent
Published: February 2016

Sequent occupance is a concept and methodology first proposed in 1929 by geographer Derwent Whittlesey. Designed to provide regional or chorological studies with a method to aid in comparison and generalization of chorographic data, the approach gained practitioners through the 1930s and 1940s with a decline by the 1950s. Rural settings were most popular initially, but the concept applied to the urban sphere has proven more durable. Occasional studies within the tradition continue up to the present, with an independent trajectory outside geography taking hold in the urban and planning fields.

Published: February 2016

Antarctica is the southernmost continent, centered around the South Pole and almost entirely covered by a thick layer of ice. If melted, this ice sheet would cause a rise in sea level of almost 60 m. The shape and volume of the ice sheet are determined by the difference between gain by snow fall and loss by ice flow. Both mechanisms are climate sensitive and have different response times. For several decades, the Antarctic ice sheet has been surveyed by remote sensing which is essential for modeling the ice sheet and understanding the mechanisms at work. In particular, laser and radar altimetry provide elevation changes with time while gravimetry provides mass changes. These sensors show that even if the large eastern part seems to be in equilibrium, the western part displays a worrying behavior with a clear acceleration in the discharge of several outlet glaciers.
