Marginal Fluctuations of a Svalbard Surge-Type Tidewater Glacier, Blomstrandbreen, Since the Little Ice Age: A Record of Three Surges

ABSTRACT Previous advances and retreats of Blomstrandbreen within the cold period known as the Little Ice Age, between approximately 1400 and 1920, are relatively well documented. The seafloor characteristics associated with these glacier fluctuations, and their importance for the identification of similar surge-type tidewater glaciers, are discussed. We use detailed multibeam-bathymetric data acquired within Nordvågen, the marine area offshore of Blomstrandbreen, to provide a new understanding of the style and pattern of deglaciation around Blomstrandhalvøya since Blomstrandbreen's neoglacial maximum. Glacial landforms on the seafloor of Nordvågen comprise overridden moraines, glacial lineations, terminal moraines, and annual recessional moraines. Crevasse-fill ridges, which are often regarded as a characteristic landform of surging tidewater glaciers, are present on only restricted areas of Nordvågen. Significantly, this study shows that large terminal surge moraines and numerous crevasse-fill ridges may not always be well developed in association with glacier surges, with implications for the identification of surges in the geological record. Using historical observations, aerial photographs, and satellite imagery of Blomstrandbreen, we have correlated former ice-marginal positions with mapped submarine landforms. Three surge events occurred during a pattern of overall retreat, with a spacing of about 50 years between active advance phases; this represents a relatively short quiescent phase for Svalbard glaciers. Average retreat rates of 10–50 m yr-1 are typical of the quiescent phase of the surge cycle, whereas surge advances vary from 200 m to over 725 m.
Positive and Negative Superhumps of the Dwarf Nova MN Dra

We present the result of O-C analysis of the dwarf nova MN Dra. It is based on the multi-site photometric observations that were made over 77 nights in August - November, 2009. The total exposure was 433 hours. During this time binary underwent two superoutbursts and five normal outbursts. In superoutbursts the positive superhumps decreased with extremely large ˙ P = −(3 − 8) × 10 �4 for SU UMa-like dwarf novae, confirming the known behavior of MN Dra in 2003. MN Dra displayed large-amplitude (up to 1.4 m in quiescence and 0.1 m -0.2 m in normal outbursts) negative superhumps. The improved value of negative superhump period is 0.095952(4) d.
When geometric phases turn topological

Geometric phases, accumulated when a quantum system traces a cycle in quantum state space, do not depend on the parametrization of the cyclic path, but do depend on the path itself. In the presence of noise that deforms the path, the phase gets affected, compromising the robustness of possible applications, e.g. in quantum computing. We show that for a special class of spin states, called anticoherent, and for paths that correspond to a sequence of rotations in physical space, the phase only depends on topological characteristics of the path, in particular, its homotopy class, and is therefore immune to noise.
Taking State-Capacity Research to the Field: Insights from Collaborations with Tax Authorities

No modern state can exist in the long term without effective taxation. Recent research emerging from close collaboration of academics with tax authorities has shed new light on how states can build such tax capacity. Using both randomized and natural experiments, these partnerships have not only opened access to new types of data but have also stimulated new perspectives and research questions. While much of research in public finance has historically assumed that a tax in the law is a tax that is collected, exciting new research takes an empirical look inside the black box of tax administration. It addresses issues ranging from the role of information and digitalization to taxpayer behavior or to the link between taxation and citizens’ relationship to the state. This article provides a brief overview of some of this research, as well as practical advice for those interested in implementing research in partnership with tax authorities or other large public entities.

Effect of Green Organizational Identity, Green Shared Vision, and Organizational Citizenship Behavior for the Environment on Green Product Development Performance

This study extends the research literature by exploring the relations among green organizational identity (GOI), green shared vision (GSV), green product development performance (GPDP), and organizational citizenship behavior for the environment (OCBE). Hypotheses were tested through structural equation modeling from a sample of 475 valid questionnaire respondents. The two main findings were as follows: (1) Positive effects for GOI and GSV between OCBE and GPDP and (2) Positive effects of OCBE for GPDP. The results further indicate that the relations among the GOI, GSV, and GPDP were partially mediated by the OCBE; the results point that the OCBE acts as mediator between GOI, GSV, and GPDP. After further examining the collecting data, we found (3) the relationship between GOI and GPDP is completely mediated by OCBE and (4) the relationship between GSV and GPDP is partially mediated by OCBE. These findings indicate that OCBE is critical in the GPDP of companies. Therefore, companies must develop the GOI and GSV to strengthen their OCBE and intensify their GPDP.
Gamma ray induced genetic improvement of sorghum landraces for grain yield and charcoal rot tolerance

Sorghum is an important cereal crop used for food, livestock feed and biofuel. In order to improve rabi sorghum (post-rainy season), which are mainly used for human consumption, physical and chemical mutagens are used to create genetic variability for quantitative traits. Two advanced sorghum mutant populations, TJP 1-5 and TC-2 were subjected to gamma ray irradiation (300 Gy) and treated with 0.2% EMS. Selections were carried out for grain yield and charcoal rot tolerance from M2 generation onwards along with check varieties. In M3 generation, 300 mutant lines were selected and screened for charcoal rot disease using tooth pick method. Based on the field screening, TCM-38, TCM-95, TJM-6-1 and TJM-35 showed less sclerotial growth (1.92, 2.08, 1.92 and 1.61 nodes crossed respectively) with high grain yield. Among all the mutants screened, TJM-35 had least mean length of fungal growth (13.47 cm) which translated into less lodging (21.74%) and better grain yield (2583 kg/ha) compared to check. Wide genetic variability was created for grain yield (354-2874 Kg/ha as against SPV-86 check, 1499 kg/ha) with mean value of 1833 Kg/ha). Among all the mutants studied, TJM-35, TJM 6-1 and TCM-95 were not only high yielding but also possess tolerance to charcoal rot disease.
Application of Acceleration-based Damage Detection Algorithms to Experimental Data from Multi-story Steel Structures

This paper presents a recent shake table experiment on two three-story steel frame structures with controllable damage. The performance and accuracy of SnowFort, a wireless infrastructure monitoring system, were tested. By analyzing the data, we show that this new system achieves the same accuracy as the wired sensing units. In addition, a structural damage detection algorithm based on Continuous Wavelet Transform was validated based on the experimental data. doi: 10.12783/SHM2015/143
Entanglement Entropy and D1-D5 geometries

In Conformal Field Theories with a gravitational AdS dual it is possible to calculate the entanglement entropy of a region $A$ holographically by using the Ryu-Takayanagi formula. In this work we consider systems that are in a pure state that is not the vacuum. We study in particular the 2D Conformal Field Theory dual to type IIB string theory on AdS$_3 \times S^3 \times T^4$ and focus on the $1/4$-BPS states described holographically by the 2-charge microstate geometries. We discuss a general prescription for the calculation of the entanglement entropy in these geometries that are asymptotically AdS$_3 \times S^3$. In particular we study analytically the perturbative expansion for a single, short interval: we show that the first non-trivial terms in this expansion are consistent with the expected CFT structure and with previous results on the vevs of chiral primary operators for the $1/4$-BPS configurations.

Topics covered include an analysis of when it is profitable to offer quantity discounts and bundle discounts, connections between secondand third-degree price discrimination, the use of market demand functions to calculate nonlinear tariffs, the impact of consumers with bounded rationality, bundling arrangements between separate sellers, and the choice of prices for upgrades and add-on products.
Kerr-Free Three-Wave Mixing in Superconducting Quantum Circuits

Quantum-limited Josephson parametric amplifiers are crucial components in circuit QED readout chains. The dynamic range of state-of-the-art parametric amplifiers is limited by signal-induced Stark shifts that detune the amplifier from its operating point. Using a Superconducting Nonlinear Asymmetric Inductive eLement (SNAIL) as an active component, we show the ability to in situ tune the device flux and pump to a dressed Kerr-free operating point, which provides a 10-fold increase in the number of photons that can be processed by our amplifier, compared to the nominal working point. Our proposed and experimentally verified methodology of Kerr-free three-wave mixing can be extended to improve the dynamic range of other pumped operations in quantum superconducting circuits.
STUDY ABOUT BUCKLING PHENOMENON IN PERFORATED THIN STEEL PLATES EMPLOYING COMPUTATIONAL MODELING AND CONSTRUCTAL DESIGN METHOD

PERFORATED STEEL THIN PLATES ARE COMMONLY USED IN STRUCTURAL ENGI-NEERING. DUE TO THEIR GEOMETRIC CHARACTERISTICS, THESE PANELS CAN SUFFER THE UNDESIRED BUCKLING PHENOMENON. IN THIS CONTEXT, THE PRESENT WORK ASSOCIATES THE COMPUTATIONAL MODELING AND THE CONSTRUCTAL DESIGN METHOD TO EVALUATE THE INFLUENCE OF THE GEOMETRIC CONFIGURATION IN THE PLATE BUCKLING BEHAVIOR, USING THE EXHAUSTIVE SEARCH METHOD TO DETERMINE WHICH GEOMETRIES CONDUCT TO SUPERIOR MECHANICAL BEHAVIOR. TO DO SO, NUMERICAL MODELS ARE EMPLOYED TO SOLVE ELASTIC AND ELASTO-PLASTIC BUCKLING OF PLATES HAVING A CENTERED PERFORATION. DIFFERENT HOLE TYPES (LONGITUDINAL OBLONG, TRANSVERSAL OBLONG, ELLIPTICAL, RECTANGULAR, DIAMOND, LONGITUDINAL HEXAGONAL, OR TRANSVERSAL HEXAGONAL) WITH DIFFERENT SHAPES (VARIATION OF CHARACTERISTICS DIMENSIONS OF EACH HOLE TYPE) ARE ANALYZED. LIMIT CURVES TO AVOID BUCKLING WERE OBTAINED, AS WELL AS THE DEFINITION OF THE GEOMETRIES THAT CAN IMPROVE UP TO 107% THE PLATE PERFORMANCE.
Distributed optical fibre audible frequency sensor

A distributed optical fibre sensor is demonstrated which is capable of quantifying acoustic and dynamic strain disturbances along a 1km sensing fibre. A phase-OTDR technique is used to detect the dynamic perturbations using the phase-difference between the backscattered light from two separate sections of the sensing fibre. The demonstrated sensor detects multiple dynamic perturbations simultaneously within a frequency range of 200Hz to 5000Hz with a frequency resolution of 10Hz and a spatial resolution of 1m.
No Time to Think: Food Decision-Making under Time Pressure

Does time pressure a ect the cognitive process and the subsequent quality of food choices? We use Dual-Process (DP) and Drift Di usion (DD) models to show that the cognitive process behind food decision-making is subject to significant changes under time constraints. Speci cally, we nd that consumers tend to make faster decisions under time limitations, therefore they accumulate less product information compared to the control condition. They spend less time encoding pre-decisional product stimuli and have more information accumulation speed to conclude choice tasks. However, faster decisions turn out to be costly, increasing sub-optimal food choices. With the help of the DP model, we document the con ict between the heuristic and value-based decision-making processes due to the time constraint. Furthermore, the heuristic process becomes more active in the treatment condition. Overall, our results show that exposing consumers to less, but crucial food information, improves the quality of food choices
Frequency and phenotype of SPG11 and SPG15 in complicated spastic paraplegia (HSP)

Background: Hereditary spastic paraplegias (HSP) are clinically and genetically highly heterogeneous. Recently two novel genes, SPG11(spatacsin) and SPG15 (spastizin), associated with autosomal recessive HSP (AR-HSP) were identified. Clinically, both are characterized by complicated HSP and a rather similar phenotype consisting of early onset spastic paraplegia, cognitive deficits, thin corpus callosum (TCC), peripheral neuropathy and mild cerebellar ataxia. Objective: To compare the frequency of SPG11 and SPG15 in patients with early onset complicated HSP and to further characterize the phenotype of SPG11 and SPG15. Results: A sample of 36 index patients with early onset complicated HSP and a family history compatible with autosomal recessive inheritance was collected and screened for mutations in SPG11 and SPG15. Overall frequency of SPG11 was 14% (5 out of 36) but was considerably higher in patients with TCC (42%). One single patient with mental retardation and thinning of the corpus callosum was compound heterozygous for two novel SPG15 mutations. Additionally, several new polymorphisms and sequence variants of unknown significance have been identified in the SPG15 gene. Conclusions: TCC seems to be the best phenotypic predictor for SPG11 as well as SPG15. No clinical features could discriminate between SPG11 and SPG15. Therefore priority of genetic testing should be driven by mutation frequency that appears to be substantially higher in SPG11 than in SPG15.
Full-Scale Testing of Deep Wide-Flange Steel Columns under Multi-Axis Cyclic Loading : 1 Loading Sequence , Boundary Effects and Out-of-Plane Brace Force Demands 2

1 Loading Sequence, Boundary Effects and Out-of-Plane Brace Force Demands 2 Ahmed Elkady, Ph.D.1, Dimitrios G. Lignos, A.M.ASCE2 3 Abstract: This paper discusses the findings from ten full-scale steel column tests subjected to 4 multi-axis cyclic loading. The columns utilize deep wide-flange cross-sections typically seen in 5 steel moment-resisting frames designed in seismic regions. The effects of boundary conditions, 6 loading sequence, local web and member slenderness ratios on the column hysteretic behavior are 7 investigated. The test data underscores the influence of boundary conditions on the damage 8 progression of steel columns. Local buckling followed by out-of-plane deformations near the 9 plastified column base are the dominant failure modes in fixed base columns with a realistic flexible 10 top end. Twisting may occur only at drifts larger than 3% even when the member slenderness is 11 fairly large. The test data suggest that bidirectional loading amplifies the out-of-plane deformations 12 but does not significantly affect the overall column performance. The loading sequence strongly 13 affects the column’s plastic deformation capacity but only at story-drifts larger than 2%. After this 14 drift amplitude, column axial shortening grows exponentially and becomes a controlling failure 15 mode. Measurements of out-of-plane brace force demands at the column top exceed the lateral 16 brace design force specified in North American standards. 17
Chapter 10. The effects of task type and L2 proficiency on discourse appropriacy in oral task performance

Conceived within the TBLT framework, the present study examined pedagogic tasks as vehicles for demonstrating L2 learners’ discourse appropriacy in oral production. Eighty ESL learners’ discourse appropriacy was measured using three pragmatically-oriented task types (complaint, refusal, and advice) across four different proficiency levels. The findings showed that, for all task types, as general proficiency increased, ratings of discourse appropriacy also increased. We found that there was a pronounced difference in discourse appropriacy between the intermediate and advanced proficiency levels, and that for learners at higher levels of proficiency, discourse appropriacy did not vary from task to task. In contrast, task type made a difference for less proficient learners in that the refusal task was particularly challenging compared with other tasks.
Running title : N-acyl-homoserine lactone quorum sensing switching from 25 acidogenesis to solventogenesis in Serratia marcescens

28 N-acyl-homoserine lactone quorum sensing (AHL-QS) has been shown to regulate 29 many physiological behaviors in Serratia marcescens MG1. In the current study, the 30 effects of AHL-QS on the biosynthesis of acid and neutral products by S. marcescens 31 MG1 and its isogenic ΔswrI with or without supplementing exogenous 32 N-hexanoyl-L-homoserine lactone (C6-HSL) were systematically investigated. The 33 results showed that swrI disruption resulted in rapid pH drops from 7.0 to 4.8, which 34 could be restored to wild type by supplementing C6-HSL. Furthermore, fermentation 35 product analysis indicated that ΔswrI could lead to obvious accumulation for 36 acidogenesis products such as lactic acid and succinic acid, especially excess acetic 37 acid (2.27 g/L) produced at the early stage of fermentation, whereas solventogenesis 38 products by ΔswrI appeared noticeable decrease by approximate 30% for acetoin 39 during 32-48 h and by approximate 20% for 2,3-butanediol during 24-40 h, when 40 compared to those by wild type. Interestingly, the excess acetic acid produced could 41 be removed in an AHL-QS-independent manner. Subsequently, quantitative real-time 42 PCR was used to determine the mRNA expression levels of genes responsible for 43 acidogenesis and solventogenesis and showed consistent results with those of product 44 synthesis. Finally, by close examination of promoter regions of the analyzed genes, 45 four putative luxI box-like motifs were found upstream of genes encoding acetyl-CoA 46 synthase, lactate dehydrogenase, α-acetolactate decarboxylase, and Lys-like regulator. 47 The information from this study provides a novel insight into the roles played by 48 AHL-QS in switching from acidogenesis to solventogenesis in S. marcescens MG1. 49
Growth and survival of the `fitter'? Evidence from US new-born firms

We examine market selection mechanisms and their strength for a representative cohort of US new independent firms. In particular, we explore whether and how effectively markets reward newly-born firms according to their `fitness' in terms of both labour productivity and profitability. Our analysis yields puzzling results in contrast with canonical industry dynamics models. First, we find that selection on differential growth is mainly related to productivity while profitability plays a negligible role. Second, in contrast with the growth of the fitter principle, selection appears to be driven by changes in firms' relative productivity. Third, we explore how new firms' relative fitness affects their growth performance in different sectors. Our results reveal that market selection operates quite differently across them with higher incidence for new-born firms in services, low-tech and less concentrated sectors. Fourth, concerning selection via exit, our results support the survival of the fitter principle with respect to productivity, while relative profitability does not seem to exert any significant effect on survival probabilities. However, the contribution of firm relative `fitness' to the total firm exit rates variation appears to be modest.
The Effect of Director Experience on Acquisition Performance

Prior research finds that firms hire directors for their acquisition experience, regardless of acquisition quality (whether their prior acquisitions earned positive or negative announcement returns). Using several short- and long-run measures, we examine the effects of directors’ acquisition experience on the acquisition performance of firms hiring them. We find that board acquisition experience is positively related to subsequent acquisition performance, demonstrating that firms appropriately value experience. Beyond experience itself, however, the quality of directors’ prior acquisitions is also important. Our results suggest that firms may be better served to select directors based upon both past acquisition experience and acquisition performance.
Teaching Mentors: Is It Worth the Effort?

Abstract Two groups of undergraduate students participating in a field experience as part of the undergraduate teacher preparation program were compared on the basis of the supervisory practice of the cooperating/mentor teacher. Both groups received a traditional orientation to student teaching and supervision. In addition, the experimental group had teachers that received an in-depth training in supervision using a specific framework, Praxis III/Pathwise (Educational Testing Service, 1995). Results demonstrated statistically significant differences in favor of the experimental group on 11 of the 19 variables investigated.
Quadratic-in-spin effects in the orbital dynamics and gravitational-wave energy flux of compact binaries at the 3PN order

We investigate the dynamics of spinning binaries of compact objects at the next-to-leading order in the quadratic-in-spin effects, which corresponds to the third post-Newtonian order (3PN). Using a Dixon-type multipolar formalism for spinning point particles endowed with spin-induced quadrupoles and computing iteratively in harmonic coordinates the relevant pieces of the PN metric within the near zone, we derive the post-Newtonian equations of motion as well as the equations of spin precession. We find full equivalence with available results. We then focus on the far-zone field produced by those systems and obtain the previously unknown 3PN spin contributions to the gravitational-wave energy flux by means of the multipolar post-Minkowskian wave generation formalism. Our results are presented in the center-of-mass frame for generic orbits, before being further specialized to the case of spin-aligned, circular orbits. Based on the energy balance equation, we derive the orbital phase of the binary at the order 3PN including all conservative spin effects and briefly discuss the relevance of the new terms.
Utilizing Second Order Information in Minibatch Stochastic Variance Reduced Proximal Iterations

We present a novel minibatch stochastic optimization method for empirical risk minimization of linear predictors. The method efficiently leverages both sub-sampled first-order and higher-order information, by incorporating variance-reduction and acceleration techniques. We prove improved iteration complexity over state-of-the-art methods under suitable conditions. In particular, the approach enjoys global fast convergence for quadratic convex objectives and local fast convergence for general convex objectives. Experiments are provided to demonstrate the empirical advantage of the proposed method over existing approaches in the literature.
