High-speed standard magneto-rotational instability

The large Reynolds number asymptotic approximations of the neutral curve of Taylor–Couette flow subject to an axial uniform magnetic field are analysed. The flow has been extensively studied since the early 1990s as the magneto-rotational instability (MRI) occurring in the flow may explain the origin of the instability observed in some astrophysical objects. Elsewhere, the ideal approximation has been used to study high-speed flows, which sometimes produces paradoxical results. For example, ideal flows must be completely stabilised for a sufficiently strong applied magnetic field. On the other hand, the vanishing magnetic Prandtl number limit of the stability should be purely hydrodynamic, so instability must occur when Rayleigh’s stability condition is violated. Our first discovery is that this apparent contradiction can be resolved by showing the abrupt appearance of the hydrodynamic instability at a certain critical value of the magnetic Prandtl number. This is found using the asymptotically large Reynolds number limit but with a sufficiently long wavelength to retain some diffusive effects. Our second finding concerns the so-called Velikhov–Chandrasekhar paradox, namely the mismatch of the zero external magnetic field limit of the Velikhov–Chandrasekhar stability criterion and Rayleigh’s stability criterion. We show for fully wide-gap cases that the high Reynolds number asymptotic analysis of the MRI naturally yields the simple stability condition that describes smooth transition from Rayleigh to Velikhov–Chandrasekhar stability criteria with increasing Lundquist number.
Equilibrium Strategies for Processor Sharing and Random Queues with Relative Priorities

We consider a memoryless single-server queue in which users can purchase relative priority so as to reduce their expected waiting costs, which are linear with time. Relative priority is given in proportion to a price paid by customers present in the system. For two service disciplines, (weighted) processor sharing and (weighted) random entrance, we find the unique pure and symmetric Nash equilibrium price paid by the customers.
Properties of length-apodized LPGs operating at the phase matching turning point

The characteristics of length-apodized phase- shifted fibre optic long period gratings with full and partial nanostructured coatings have been explored theoretically and experimentally. The twin rejection bands that are characteristic of the length-apodized phase-shifted long period gratings are studied for a long period grating (LPG) operating at the phase matching turning point. When one half of the length of the LPG is coated, complex bandgap like structure appears within the transmission spectrum, which may be of benefit to spectral filter design.
SETD 6 mono-methylates H 2 AZ on lysine 7 ( H 2 AZK 7 me 1 ) and is required for the maintenance of embryonic stem cell self-renewal

The histone H2A variant H2AZ is an essential chromatin signaling factor. Herein, we report that H2AZ is mono-methylated at lysine 7 (H2AZK7) by the lysine methyltransferase SETD6. We observed that methylation of H2AZ increased noticeably upon cellular differentiation of mouse embryonic stem cells (mESC). H2AZK7 and the repressive H3K27 mark were found near the transcriptional start sites of differentiation marker genes, but were removed upon retinoic acid-induced cellular differentiation. The depletion of Setd6 in mESC led to cellular differentiation, compromised self-renewal, and poor clonogenicity. These findings demonstrate that mESC require Setd6 for self-renewal and portray H2AZK7 as a marker of cellular differentiation.
Evaluation of Boolean Formulas with Restricted Inputs by Bohua Zhan

In this thesis, I will investigate the running time of quantum algorithms for evaluating boolean functions when the input is promised to satisfy certain conditions. The two quantum algorithms considered in this paper are the quantum walk algorithm for NAND trees given by Farhi and Gutmann [2], and an algorithm for more general boolean formulas based on span programs, given by Reichardt and Spalek [6]. I will show that these algorithms can run much faster on a certain set of inputs, and that there is a super-polynomial separation between the quantum algorithm and the classical lower bound on this problem. I will apply this analysis to quantum walks on decision trees, as described in [3], giving a class of decision trees that can be penetrated quickly by quantum walk but may not be efficiently searchable by classical algorithms.

Higher prevalence of X-ray selected AGN in intermediate-age galaxies up to z ̃ 1

We analyse the stellar populations in the host galaxies of 53 X-ray selected optically dull active galactic nuclei (AGN) at 0.34 10^10.5 M_sun) and that the observed fraction of galaxies hosting an AGN increases with the stellar mass. A careful selection of random control samples of inactive galaxies allows us to remove the stellar mass and redshift dependencies of the AGN fraction to explore trends with several stellar age indicators. We find no significant differences in the distribution of the rest-frame U-V colour for AGN hosts and inactive galaxies, in agreement with previous results. However, we find significantly shallower 4000 AA breaks in AGN hosts, indicative of younger stellar populations. With the help of a model-independent determination of the extinction, we obtain extinction-corrected U-V colours and light-weighted average stellar ages. We find that AGN hosts have younger stellar populations and higher extinction compared to inactive galaxies with the same stellar mass and at the same redshift. We find a highly significant excess of AGN hosts with Dn(4000)~1.4 and light weighted average stellar ages of 300-500 Myr, as well as a deficit of AGN in intrinsic red galaxies. We interpret failure in recognising these trends in previous studies as a consequence of the balancing effect in observed colours of the age-extinction degeneracy.
Crowdfunding: Disintermediated Investment Banking

This paper introduces crowdfunding as a concept and model for the evolution of investment banking. Crowdfunding, an application of crowdsourcing, is defined as one party’s attempt to finance a project by offering three types of investment opportunities to potential investors. The investment opportunities are donations, passive investments, and active investments. From this foundation I develop a model in which interdependent agents operate in a dynamic, discrete setting. Potential investors decide whether or not to invest in one of three opportunities each period while the entrepreneur sets the parameters of the game to maximize the probability of successful financing. I then simulate the model to analyze the effects changes in key parameters have on the results of the game.

Discourse analysis and constructionist approaches: theoretical background

This chapter is structured in terms of questions and answers. There are several reasons for adopting this format. First, people often consult a handbook to find the answers to questions so the format may simplify this task. Second, most constructionist approaches place a considerable emphasis on dialogueand question-answer sequences are dialogue in one of its most prototypical forms. Third, constructionist researchers have been at the forefront of moves to rethink the literary forms in which social science is presented. I shall start with some general questions about constructionism and its place in psychology, and then I shall move on to focus on issues of method and analysis. I shall concentrate upon general principles and arguments, however, this is not intended to be a how-to-do-it chapter. Chapter 11, by Rosalind Gill, provides a more fleshed out example of a particular style of constructionist research.
Factors Influencing the Pitch-Matching of Junior High Boys

The skill of pitch-matching is a prerequisite for even the most casual musical participation. While singing accuracy has been carefully researched at the elementary level, there has been comparatively less research done with adolescents. The purpose of the study described here was to examine the influence of perceptual ability, task demands, and singing range on the pitch-matching performance of adolescent boys in various stages of the voice change. We found significant differences between certain, inconsistent, and uncertain singers in their perceptual skills and found that a contextual pitch-matching condition was significantly easier than a single-pitch condition. There was no difference by singing range. Future research should explore the progression of these skills longitudinally and continue to examine performance related to different task demands.
Spelling-to-Sound Correspondences for Reading vs. Sound-to-Spelling Correspondences for Writing.

Differences between spelling-to-sound correspondences for reading and sound-to-spelling correspondences for writing are discussed in terms of the characteristics of and the relationships between stimuli and responses. While dialect variation can be accommodated in reading, it cannot be accommodated in spelling, where no response variation is permitted. Correspondences are not generally reversible, and complementary correspondences differ in complexity. Implications for the design of a spelling component within a unifiel communication skills program are presented. (Author) SPELLING-TO-SOUND CORRESPONDENCES FOR READING VS.

Tropical tropopause layer

Observations of temperature, winds, and atmospheric trace gases suggest that the transition from troposphere to stratosphere occurs in a layer, rather than at a sharp “tropopause. ” In the tropics, this layer is often called the “tropical tropopause layer” (TTL). We present an overview of observations in the TTL and discuss the radiative, dynamical, and chemical processes that lead to its time‐varying, three‐dimensional structure. We present a synthesis definition with a bottom at 150 hPa, 355 K, 14 km (pressure, potential temperature, and altitude) and a top at 70 hPa, 425 K, 18.5 km. Laterally, the TTL is bounded by the position of the subtropical jets. We highlight recent progress in understanding of the TTL but emphasize that a number of processes, notably deep, possibly overshooting convection, remain not well understood. The TTL acts in many ways as a “gate” to the stratosphere, and understanding all relevant processes is of great importance for reliable predictions of future stratospheric ozone and climate.
PI3Kβ inhibitor AZD6482 exerts antiproliferative activity and induces apoptosis in human glioblastoma cells

Glioblastoma is the most common type of primary brain tumour in adults, and its pathogenesis is particularly complicated. Among the many possible mechanisms underlying its pathogenesis, hyperactivation of the PI3K/Akt pathway is essential to the occurrence and development of glioma through the loss of PTEN or somatic activating mutations in PIK3CA. In the present study, we investigated the effect of the PI3Kβ inhibitor AZD6482 on glioma cells. The CCK-8 assay showed dose-dependent cytotoxicity in glioma cell lines treated with AZD6482. Additionally, AZD6482 treatment was found to significantly induce apoptosis and cell cycle arrest as detected using flow cytometry. Moreover, as shown using western blot analysis, the levels of p-AKT, p-GSK-3β, Bcl-2, and cyclin D1 were decreased after AZD6482 treatment. In addition, we found that AZD6482 inhibited the migration and invasion of glioma cells as detected by wound healing and Transwell invasion assays. Taken together, our findings indicate that AZD6482 exerts an antitumour effect by inhibiting proliferation and inducing apoptosis in human glioma cells. AZD6482 may be applied as an adjuvant therapy to improve the therapeutic efficacy of glioblastoma treatment.
Introducing intellectual potential

Intellectual capital has gained increasing attention concerning both research and more practically oriented applications during the past five years. Intellectual Capital and other knowledge management tools are topics that have emerged in the light of a broader trend of redirecting the foundation of competitive advantage from the company's tangible assets to its intangibles such as knowledge base, brands and the content and structure of computer‐based systems. In this paper, the concept of intellectual potential is introduced. Intellectual potential is a further development of intellectual capital, using four principles: strategy basis; management orientation; process orientation; and context sensitivity. The concept is a tool for the strategic management of an organisation's intangible assets in order to increase its long‐term revenue‐generating capabilities. The case of Alfa Laval is used as an illustration of how intellectual potential can add value as a management tool.
Validity and reliability of two field-based leg stiffness devices : implications for 3 practical use

18 Leg stiffness is an important performance determinant in several sporting activities. The aim of 19 this study was to evaluate the criterion-related validity and reliability of two field-based leg 20 stiffness devices, Optojump Next® (Optojump) and Myotest Pro® (Myotest) in different testing 21 approaches. Thirty-four males performed, on two separate sessions, three trials of 7 maximal 22 hops, synchronously recorded from a force platform (FP), Optojump and Myotest. Validity 23 (Pearson’s correlation coefficient,r; relative mean bias, bias;, 95% limits of agreement, 95%LoA) 24 and reliability (coefficient of variation, CV; standard error of measurement, SEM; intraclass 25 correlation coefficient, ICC) were calculated for first attempt, maximal attempt, and average 26 across three trials. For validity all three methods, Optojump correlated highly to the FP (range r = 27 0.98-0.99) with small bias (range 0.91-0.92, 95 LoA 0.86-0.98). Myotest demonstrated high 28 correlation to FP ( range r = 0.81-0.86) with large bias (range 1.92-1.93, 95% LoA 1.63-2.23). In 29 terms of reliability, Optojump yielded a low CV (range 5.9%-6.8%), SEM ranging 1.8-2.1 kN/m, 30 and high ICC (range 0.82-0.86). Myotest had a larger CV (range 8.9%-13.0%), SEM ranging 31 from 6.3-8.9 kN/m, and moderate ICC (range 0.64-0.79). The findings present important 32 information for these devices and support the use of a single trial to assess leg stiffness in the 33 field, thus testing in a time-efficient way. 34 35
Has Europe Been Catching Up? An Industry Level Analysis of Venture Capital Success Over 1985–2009

After nearly two decades of U.S. leadership in the 1980s and 1990s, are Europe's venture capital markets in the 2000s finally catching up regarding the provision of financing and successful exits, or is the performance gap as wide as ever? Are we amidst overall dismal performance of the venture capital experience without any encouraging news? We attempt to answer these questions by tracking down over 40,000 venture capital--backed firms of six industries in 13 European countries and the U.S., and determine which type of exit - if any - each particular firm's investors have chosen between 1985 and 2009. Our empirical findings suggest that: (i) in terms of the number of venture capital-backed firms successfully going public, European venture capitalists have closed the gap with respect to the U.S., albeit as a result of a worse initial public offering performance overall; (ii) Europe continues to lag behind the U.S. by means of mergers and acquisitions, and in successful exits of seed/start-up and early stage firms, (iii) average investment and RD and (iv) idiosyncratic differences across industries seem to be more relevant than country-specific characteristics in explaining differences in performance.
Sensing technology for measuring crop nitrogen

Quantitative remote sensing has advanced in its ability to measure plant and canopy parameters, with nitrogen being one of the principal components of interest for crop N management. A plethora of sensors and imagers including multispectral, hyperspectral and fluorescence with different characteristics (e.g., passive vs active) have provided researchers and the agricultural industry with choices for measurement. Platforms for mounting sensors range from handheld and tractor mounted to satellites and unmanned aerial vehicles (UAVs). How to quantify canopy N using these hardware tools with spectral indices has been the focus of research for some time. Examples of recent work integrating sensors, platforms and spectral indices will be presented for ground-based proximal fluorescence sensing and passive sensing using ground and aerial platforms.
Specialized Macro-Instructions for Von-Neumann Accelerators

In the last few decades, Von-Neumann super-scalar processors have been the superior approach for improving general purpose processing and hardware specialization was used as a complementary approach. However, the imminent end of Moore’s law indicates voltage scaling and per-transistor switching power can not scale down with the same peace as what Moore’s law predicts. As a result, there is a new interest in hardware specialization to improve performance, power and energy efficiency on specific tasks. Hardware customization so far has effectively targeted programs with abundant parallelism and simple data access patterns using vector extensions, GPUs, and spatial fabrics. However, programs with diverse control and memory behavior have found it challenging to leverage these accelerators. Our work is motivated by observing two main approaches in designing hardware accelerators. First many proposals [45, 20] seem to choose dataflow-based accelerators to reduce front-end energy. However, spatial fabrics encounter challenges with fabric utilization and static power when the available instruction parallelism is below the peak operation parallelism available [14]. Second, using custom or magic instructions[19, 10, 23] integrated with the core pipeline reduces both front-end (fetch and decode) and back-end (register access) costs. The problem with this method is the lack of generality across programs because the desired set of custom instructions varies. This dissertation proposes a Von-Neumann based accelerator, Chainsaw and demonstrates that many of the fundamental overheads (e.g., fetch-decode) can be amortized by adopting the appropriate instruction abstraction. To this end, we use the notion of chains, which are compiler fused sequences of instructions. chains convey the producer-consumer locality between dependent instructions, which the Chainsaw architecture then captures by temporally scheduling such operations on the same execution unit and uses bypass registers to forward the values between dependent operations. Chainsaw is a generic multi-lane architecture (4-stage pipeline per lane) and does not require any specialized compound function units; it can be reloaded enabling it to accelerate multiple program paths. We have developed a complete LLVM-based compiler prototype and simulation infrastructure and demonstrated that an 8-lane Chainsaw is within 73% of the performance of an ideal dataflow architecture while reducing the energy consumption by 45% compared to a 4-way OOO processor.
Micro- and macrodiversity in rbcL sequences in ambient phytoplankton populations from the southeastern Gulf of Mexico

Ribulose-1,5-diphosphate carboxylase/oxygenase (RuBisCO) large subunit genes (rbcL) were obtained by amplification and cloning of 554 or 614 bp sequences of indigenous phytoplankton populations at 2 stations in the southeastern Gulf of Mexico. One station (Stn 4) was located in a low salinity, high chlorophyll plume (the 'Green River') which has previously been shown to contain elevated levels of Form IA rbcL mRNA while the other (Stn 7) was in oligotrophic, oceanic water. A diversity of rbcL sequences was obtained, spanning 3 of the 4 evolutionary clades of Form I RuBisCOs. Six nucleotide sequences obtained from Stn 4 were closely related (92 to 96% similar) to the Form IA-containing Prochlorococcus GP2. Flow cytometry and pigment analysis indicated that Prochlorococcus was abundant at this site. Other sequences found included a Form IB rbcL closely related to prasinophytes, and Form ID sequences related to prymnesiophytes, diatoms, and pelagophytes. One sequences was nearly identical to the pelagophyte, Pelagomonas calceolata. At Stn 7, sequences were obtained that were more deeply rooted, and less similar to rbcLs in existing databases (77 to 83% similar), and no Form IA rbcLs were detected. HPLC pigment signatures and flow cytometry data were consistent with the forms obtained by cloning. The similarity of the 6 Prochlorococcus GP2-like sequences (93 to 98%) is consistent with the phenomenon of molecular microdiversity as found at other loci in marine (and other environmental) microorganisms.
