Beyond boundaries of redshift surveys: assessing mass fluctuations on "super-survey" scales

The observed density field in redshift space is directly affected by the radial motions generated from mass fluctuations outside the volume occupied by a given galaxy redshift survey. These motions introduce redshift space anisotropies which are more pronounced at larger distances from the survey's center, thus offering clues to the nature of mass fluctuations on super-survey scales. Furthermore, we note that all estimates of the growth factor derived from redshift space distortions are based on relations which explicitly assume that the velocity field is generated by mass fluctuations inside the survey volume. This may cause uncertainties in these estimates which are on the order of a few percent.
A RING OF C2H IN THE MOLECULAR DISK ORBITING TW Hya

We have used the Submillimeter Array to image, at ∼1. ″5 resolution, C2H N = 3 → 2 ? > emission from the circumstellar disk orbiting the nearby (D = 54 pc), ∼8 Myr-old, ∼0.8 M ⊙ ? > classical T Tauri star TW Hya. The SMA imaging reveals that the C2H emission exhibits a ring-like morphology. Based on a model in which the C2H column density follows a truncated radial power-law distribution, we find that the inner edge of the ring lies at ∼45 AU, and that the ring extends to at least ∼120 AU. Comparison with previous (single-dish) observations of C2H N = 4 → 3 ? > emission indicates that the C2H molecules are subthermally excited and, hence, that the emission arises from the relatively warm ( T ≳ 40 ? > K), tenuous ( n ≪ 10 7 ? > cm−3) upper atmosphere of the disk. Based on these results and comparisons of the SMA C2H map with previous submillimeter and scattered-light imaging, we propose that the C2H emission most likely traces particularly efficient photo-destruction of small grains and/or photodesorption and photodissociation of hydrocarbons derived from grain ice mantles in the surface layers of the outer disk. The presence of a C2H ring in the TW Hya disk hence likely serves as a marker of dust grain processing and radial and vertical grain size segregation within the disk.
Event-Triggered Adaptive Bipartite Asymptotic Tracking Control Using Intelligent Technique for Stochastic Nonlinear Multiagent Systems

The problem of event-triggered-based adaptive bipartite asymptotic tracking control for multiagent stochastic pure-feedback nonlinear systems over sign digraph is considered. The agents classification optimization strategy (ACOS) is presented, which transforms a structurally unbalanced multiagent topology graph into a structurally balanced multiagent topology graph. Furthermore, how to deal with the nonaffine structure and unknown control gains for multiagent stochastic pure-feedback nonlinear systems is a challenging issue for designing controllers. As a result, the mean value theorem is used to transfer the nonaffine systems into the affine systems, and the Nussbaum functions are used to eliminate the influence caused by the unknown control gains. In addition, the intelligent control technique is used to approximate the unknown nonlinearities, the event-triggered control strategy following the switching thresholds is introduced to save unnecessary communication resources, and the computation burden is eliminated by means of the dynamic surface technique. It is proved that all signals of the closed-loop systems are bounded in probability and the tracking errors asymptotically converge to zero in probability. Finally, the simulation results illustrate the validity of the proposed scheme.
Numerical modeling of particle transport and acceleration of solar flare particles in a coronal loop

We examine the behavior of energetic particles in a flaring solar coronal loop under the assumption that a uniform turbulent MHD wave field causes the particles to diffuse in momentum and real space. The analytical formulation of these processes, presented in a previously published work, is restricted by the choice of a simple energy and spatial dependence of the diffusion coefficients and the collisional energy loss term. Although good agreement is evident between the predicted and the observed time profiles when the model is applied to the 1982 June 3 flare, we have constructed a numerical model which will allow us to relax the constraints inherent in the analytical version. Progress in applying this numerical model is presented.
The Influential Factors on Customer Loyalty Based on Marketing Mix Theory

With the rapid growth of China's luxury market, many luxury brands have shifted their sales focus to China, in which resulting in many brands taking root in China one after another. The purpose of this report was to explore how Hermes utilized its marketing methods to influence customers' loyalty. A good marketing strategy can not only bring better benefits to the company but also reflect the influence of a brand in the market to a great extent. And this paper was based on SWOT analysis by adding 4Ps into the model, and it was appropriate to analyze which sectors will affect loyalty more. Based on SWOT analysis, the paper can find that product and price are the biggest factors affecting customer loyalty because product and price are the faces of a brand, and play a very important role. Even though product and price are very important, promotion and location in 4Ps also have little impact on customers. However, if compared with price and product, its impact is less obvious.
Clinical outcomes of asymptomatic low-grade esophagitis: results from a multicenter Chinese cohort

Abstract Background Asymptomatic low-grade (Los Angeles Classification Grades A and B) esophagitis is common in clinical practice with unclear clinical outcomes. This study aimed to explore the clinical outcomes of asymptomatic low-grade esophagitis. Methods This was a multicenter cohort study conducted by three academic hospitals in China. Asymptomatic low-grade esophagitis patients between January 2015 and December 2019 were included. Mucosal healing condition 1 year after initial diagnosis, symptom outcomes, and proton-pump inhibitor (PPI) use within 1 year after initial diagnosis were studied and compared. Results A total of 248 asymptomatic low-grade esophagitis patients were included. Esophagitis disappeared in 76.2% of patients 1 year after initial diagnosis. In terms of symptom outcomes, 89.9% of patients did not present gastroesophageal reflux disease (GERD) symptoms within 1 year after initial diagnosis. No significant difference was found in the proportion of patients who presented GERD symptoms and in the proportion of patients with persistent esophagitis between the PPI group and the non-PPI group (all P > 0.05). Patients with initial Grade B esophagitis were more likely to present follow-up GERD symptoms (16.0% vs 7.5%, P = 0.041) and had more severe follow-up esophagitis than those with Grade A (P < 0.001). Patients with follow-up GERD symptoms were more likely to have persistent esophagitis than those without. Conclusions This study demonstrated that asymptomatic low-grade esophagitis had relatively benign clinical outcomes. Patients with initial Grade B esophagitis and patients with follow-up GERD symptoms were more likely to be those who are in genuine need of further follow-up and treatments.
Component Importance for Continuum Structure Functions with Underlying Binary Structures

A continuum structure function (CSF) is a non-decreasing mapping from the unit hypercube to the unit interval. A B-type CSF, deflned in the text, is a CSF whose behaviour is modeled by its underlying binary structures. As the measure of importance of a system component for a B-type CSF, the structural and reliability importance of a component at a system level fi(0 < fi < 1) are deflned and their properties are deduced.
Training team creativity with Lego Serious Play: Upside and downside of team diversity

We trained 40 teams using Lego Serious Play (LSP), a facilitated workshop method in which the aspects of visual­ization, com­mitment, fun and shared storytelling are used. LSP improves open and participatory communication, collaborative learning and intuitive imagination and reduced ‘free ridership’ in innovation teams; it was easier to achieve a ‘train of thought’ or ‘flow’ within a team. LSP is a promising creativity method, although its effi­cacy is influenced by conditions. Teams can enhance or disrupt creative performance. Different mindsets within creative teams may lead to a broader pallet of new per­spectives in the ideation phase of inno­vation in which divergent thinking is important to explore novel viewpoints. However, diversity may lead to relationship conflicts in a team. We address the dilemma of achieving synergistic benefits from team diversity while managing negative interpersonal tensions between heterogeneous team members in relation to motivational aspects and team climate and summarize this in a significant three-path mediation model. We found a highly significant path with team performance of team diversity, com­mitment, and ‘voice’ (i.e. the extent to which team members are encouraged to express their views in the team). Team diversity has a potentially upside effect on creative performance, as well as a practical down­side effect: it can be a source of interpersonal tension and intergroup biases and consequently less commitment leading to a less open team climate, resulting in lower team performance.

The use of pre-crop values to improve farm performance: the case of dairy farms in southwest Finland

ABSTRACT Pre-crop values are used to indicate the benefits of a previous crop for a subsequent crop in crop sequencing. A better understanding and research on pre-crop values has the potential to facilitate the diversification of crop production. Despite the various benefits of diversification, the limited knowledge and incentives concerning the pre-crop values in the market conditions have contributed to the persistence of cereal-dominated land use. The present study evaluated the benefits of utilizing pre-crop values in a Finnish context. Results based on dynamic optimization modelling showed that incorporating more information on pre-crop values into farmers’ decision-making contributes to increased net present values (NPV). The adoption of pre-crop values was analysed under five different scenarios: Removal of the Common Agricultural Policy land constraints, 30% increase in labour costs, +/−10% change in crop prices, and 30% increase in N fertilizer price. Under each scenario, the response of the baseline model (without pre-crop values) was compared to the response of the model with pre-crop values. In all scenarios, the results of the model with pre-crop values showed higher NPVs, higher yields and slightly lower GHG emissions. Hence, increasing knowledge and utilization of pre-crop values may significantly promote shifts towards more sustainable agriculture.
WATER DEUTERIUM FRACTIONATION IN THE INNER REGIONS OF TWO SOLAR-TYPE PROTOSTARS

The [HDO]/[H2O] ratio is a crucial parameter for probing the history of water formation. So far, it has been measured for only three solar-type protostars and yielded different results, possibly pointing to a substantially different history in their formation. In the present work, we report new interferometric observations of the HDO 42, 2–42, 3 line for two solar-type protostars, IRAS2A and IRAS4A, located in the NGC 1333 region. In both sources, the detected HDO emission originates from a central compact unresolved region. A comparison with previously published interferometric observations of the HO 31, 3–22, 0 line shows that the HDO and H2O lines mostly come from the same region. A non-LTE large velocity gradient analysis of the HDO and HO line emissions, combined with published observations, provides an [HDO]/[H2O] ratio of 0.3%–8% in IRAS2A and 0.5%–3% in IRAS4A. First, the water fractionation is lower than that of other molecules such as formaldehyde and methanol in the same sources. Second, it is similar to that measured in the solar-type protostar prototype, IRAS16293-2422, and, surprisingly enough, larger than that measured in NGC 1333 IRAS4B. The comparison of the measured values toward IRAS2A and IRAS4A with the predictions of our gas–grain model GRAINOBLE gives similar conclusions to those for IRAS 16293, arguing that these protostars share a similar chemical history, although they are located in different clouds.
Low Temperature Transport Properties of Strongly Interacting Systems — Thermal Conductivity of Spin-1/2 Chains

We outline a general approach to the computation of transport properties of interacting systems at low temperetures and frequencies. We show that if the fixed point and the irrelevant operators around it are known, then by studying the structure of the softly violated conserved currents chracterizing the fixed point one may set up an effective calculation in terms of a memory matrix formalism. We apply this approach to the computation of thermal conductivity of spin chains embedded in a matter matrix and interacting with its phonons. The results are found to be in very good agreement with experiment.
KETERTERAPAN KONSEP COOPERATIVE COMPLIANCE PADA AKTIVITAS PENGAWASAN WAJIB PAJAK

Pendekatan deterrence kepada wajib pajak memiliki korelasi lemah terhadap kepatuhan (Kirchler, Hoelzl, & Wahl, 2008). Konsep cooperative compliance hadir sebagai pendekatan alternatif untuk hubungan antara otoritas pajak dengan wajib pajak dengan mengedepankan rasa saling percaya, kerjasama dan transparansi. Secara teori, penerapan cooperative compliance secara optimal dapat memberikan manfaat bagi otoritas pajak dan wajib pajak dari segi biaya kepatuhan, tingkat kepatuhan dan realisasi penerimaan pajak. Studi ini bertujuan untuk memahami dan mengevaluasi sejauh mana keteterapan konsep cooperative compliance dalam aktivitas pengawasan yang dilakukan oleh otoritas pajak di Indonesia. Analisis keterterapan dilakukan dengan mengevaluasi pilar cooperative compliance dalam aktivitas pengawasan yaitu commercial awareness, impartiality, proportionality, openness through disclosure and transparency by tax authority dan disclosure and transparency by taxpayer. Hasil penelitian ini menunjukkan bahwa pilar cooperative compliance belum terterapkan sepenuhnya karena beberapa hambatan. Pengaturan lebih lanjut mengenai komitmen, pengungkapan dan transparansi informasi, mekanisme pemberian kepastian, dan keterbukaan mengenai pendekatan manajemen risiko diperlukan untuk penerapan cooperative compliance secara optimal.
Façade Creation and Workplace Bullying: A Mediated Moderation Model

This study examines the buffering role of a psychological contract breach in the process leading from façade creation (i.e., suppressing one’s own values and pretending to hold organization values) to workplace bullying through leader–member exchange (LMX). This study predicts that façade creation, particularly when the level of psychological contract breach is high, produces high LMX, which reduces bullying in the workplace. In total, 302 employee–employer dyads (265 males, 37 females; average age 46.07 years) from a large bank in Taiwan were surveyed. Surveys were conducted at two time points for employees and at one time point for their employers who volunteered. The findings of this study found significant relationships between facades of conformity and workplace bullying. This study further found that LMX mediates the relationship between façade creation and workplace bullying and demonstrate that a perceived breach of psychological contract moderates this mediating pathway. Strong psychological contract breach increases the relationship between façade creation and LMX. A time-lag design of two time periods and two different sources (i.e., employers and employees) were utilized to diminish common method variables (CMV) in this study. Implications and directions for future study are discussed.
Self Organized Grouping of Ears Based on Inertia Related Biometrics Using Kohonen’s Feature Map

Classification of images based on the biometric features is a challenging problem in the field of pattern recognition and person identification. In this paper, we propose a Self Organized Feature Map (SOFM) to group ears for the purpose of person identification. A database of 605 right ear images is used to develop the recognition system. The application of SOFM permitted to differentiate four classes of ears. The features used are novel and are based on the Moment of Inertia (MI) related parameters. To elicit the parameters the ear is considered to be planner surface. Five parameters namely MI with respect to major axis and minor axis, radii of gyration (RG) with respect to major axis and minor axis, and the planner area of the ear were considered. The results show that four groups are distinct with minimum overlapping. The group characteristic has also been reported. The significance of this work is seen in decreased grouping and image retrieval time to an extent of 10% when the images in the database is organized in blocks of groups when compared to image matching and retrieval time when unorganized database is considered.
Nanostructured MoS2 and WS2 Photoresponses under Gas Stimuli

This study was on the optoelectronic properties of multilayered two-dimensional MoS2 and WS2 materials on a silicon substrate using sputtering physical vapor deposition (PVD) and chemical vapor deposition (CVD) techniques. For the first time, we report ultraviolet (UV) photoresponses under air, CO2, and O2 environments at different flow rates. The electrical Hall effect measurement showed the existence of MoS2 (n-type)/Si (p-type) and WS2 (P-type)/Si (p-type) heterojunctions with a higher sheet carrier concentration of 5.50 × 105 cm−2 for WS2 thin film. The IV electrical results revealed that WS2 is more reactive than MoS2 film under different gas stimuli. WS2 film showed high stability under different bias voltages, even at zero bias voltage, due to the noticeably good carrier mobility of 29.8 × 102 cm2/V. WS2 film indicated a fast rise/decay time of 0.23/0.21 s under air while a faster response of 0.190/0.10 s under a CO2 environment was observed. Additionally, the external quantum efficiency of WS2 revealed a remarkable enhancement in the CO2 environment of 1.62 × 108 compared to MoS2 film with 6.74 × 106. According to our findings, the presence of CO2 on the surface of WS2 improves such optoelectronic properties as photocurrent gain, photoresponsivity, external quantum efficiency, and detectivity. These results indicate potential applications of WS2 as a photodetector under gas stimuli for future optoelectronic applications.
Is it safe to harvest a proximally fractured fibula as an osseocutaneous anterograde pedicled flap for proximal tibial reconstruction in subacute period? A case report and literature review

ABSTRACT Osteoseptocutaneous fibula flap is commonly used as the workhorse flap for bone reconstruction. However, the use of previously fractured fibula as a free or pedicled flap for bone reconstruction has a limited knowledge in the literature. There is not any data in the literature about a case with proximal level of fibula fracture which was used as an anterograde pedicled osteocutaneous fibula flap for composite tibial reconstruction after high-energy injury. Based on a patient in whom the composite defect of the proximal tibial region was reconstructed with osteocutaneous fibula flap after a gunshot injury, it was tried to show that the fibula with a proximal level fracture could be used with anterograde flow in the subacute period and it is thought that the usability of this flap should be kept in mind. It is possible to harvest the pedicled fibula flap even in the subacute period with the evaluation of CT angiography preoperatively and with the checking the patency and flow direction of peroneal artery perioperatively. The success of the procedure may be increased through total dissection of inflammatory areas of pedicle which would extend into the injury zone during the subacute period.
Measuring CP-Violating Observables in Rare Top Decays at the LHC

In this paper we consider CP-violating new-physics contributions to the decay t → bbc. We examine the prospects for detecting such new physics at the LHC, which requires studying the process gg → t(→ b ¯)¯(→ ¯ bl¯ ν). We find two observables that can be used to reveal the presence of CP-violating new physics in t → bbc. They are (i) the partial-rate asymmetry and (ii) the triple-product correlations involving the momenta of various particles associated with the interaction. A Monte Carlo analysis is performed to determine how well these observables can be used to detect the presence of new physics, and to measure its parameters. We find that there is little difficulty in extracting the value of the relevant new-physics parameter from the partial-rate asymmetry. For the triple-product correlations, we test multiple strategies that can be used for the extraction of the corresponding combination of new-physics parameters.
Magnetic-field effects on p-wave phase transition in Gauss–Bonnet gravity

In the probe limit, we study the holographic p-wave phase transition in the Gauss–Bonnet gravity via numerical and analytical methods. Concretely, we study the influences of the external magnetic field on the Maxwell complex vector model in the five-dimensional Gauss–Bonnet–AdS black hole and soliton backgrounds, respectively. For the two backgrounds, the results show that the magnetic field enhances the superconductor phase transition in the case of the lowest Landau level, while the increasing Gauss–Bonnet parameter always hinders the vector condensate. Moreover, the Maxwell complex vector model is a generalization of the SU(2) Yang–Mills model all the time. In addition, the analytical results backup the numerical results. Furthermore, this model might provide a holographic realization for the QCD vacuum instability.
Minimum-cost quantum measurements for quantum information

Knowing about optimal quantum measurements is important for many applications in quantum information and quantum communication. However, deriving optimal quantum measurements is often difficult. We present a collection of results for minimum-cost quantum measurements, and give examples of how they can be used. Among other results, we show that a minimum-cost measurement for a set of given pure states is formally equivalent to a minimum-error measurement for certain mixed states of those same pure states. For pure symmetric states it turns out that for a certain class of cost matrices, the minimum-cost measurement is the square-root measurement. That is, the optimal minimum-cost measurement is in this case the same as the minimum-error measurement. These results are in agreement with Nakahira and Usuda (2012 Phys. Rev. A 86 062305). Finally, we consider sequences of individual uncorrelated systems, and examine when the global minimum-cost measurement is a sequence of optimal local measurements. We consider an example where the global minimum-cost measurement is, perhaps counter-intuitively, not a sequence of local measurements, and discuss how this is related to the Pusey–Barrett–Rudolph argument for the nature of the wave function.
