Asymptotics for random Young diagrams when the word length and alphabet size simultaneously grow to infinity

Given a random word of size $n$ whose letters are drawn independently from an ordered alphabet of size $m$, the fluctuations of the shape of the random RSK Young tableaux are investigated, when $n$ and $m$ converge together to infinity. If $m$ does not grow too fast and if the draws are uniform, then the limiting shape is the same as the limiting spectrum of the GUE. In the non-uniform case, a control of both highest probabilities will ensure the convergence of the first row of the tableau toward the Tracy--Widom distribution.
Analysis of on-Body Transponders Based on Frequency Selective Surfaces

This paper proposes a backscattering communication technique based on modulated frequency selective surfaces (FSS) for wearable applications. The FSS is composed of dipoles loaded with varactor diodes to modulate the backscatter response, in order to separate it from the clutter. The paper describes the effect in the transponder response according to the number of dipoles, the separation between them and the effect produced when FSS is placed on-body. An analysis based on simulations of several cases and experimental results is provided.
Estimates of combining ability for resistance to pod shattering in soybean (Glycine max (L.) Merrill) genotypes

Combining ability estimates were studied for pod shattering and other agronomic traits in eight parental soybean genotypes of different pod shattering group namely: susceptible to pod shattering, moderately resistant to pod shattering were crossed in a 4 x 4 North Carolina mating design II to generate 16 crosses, due to missing stands encountered in some crosses, 9 successful F1S hybrids were obtained in the present study and evaluated along with the parents to estimate the mode of gene action controlling pod shattering in soybean and the combining ability for pod shattering and other agronomic traits in soybean. The mean square from the analysis of variance for the ten traits measured showed highly significant differences (p<0.01) among the genotypes. This has demonstrated the existence of genetic variability among soybean genotypes with pod shattering under additive gene action. TGX1955-10E, NG/AD/11/08/023 and NG/SA/07/100 were good general combiners for resistance to pod shattering, plant height, days to 50% flowering and days to maturity while NG/MR/11/11/060, NGBOO/08, TGX1740-1F and NG/SA/07/055 are good general combiner for number of seeds/ pod, pod length, hundred seed weight and grain yield. NG/SA/07/100 x TGX1740-1F, NG/MR/11/11/060 x NGBOO129 and NG/MR/11/11/060 x NG/AD/11/08/023 had positive specific combining ability effects for number of branches/ plant, number of pods/plant, pod length, number of seeds/pod, hundred seed weight and grain yield. NG/MR/11/11/060 X NG/SA/07/055had negative SCA effects for plant height. This implied that these hybrids performed better than the parents GCA effects. This suggests that the cross combination can be advanced for selection in later generation. Key words: Combining ability effects, soybean genotypes, pod shattering, Samaru.
Recurrent radio activity in active galactic nuclei

There has been a growing body of persuasive evidence to indicate that AGN activity, powered by mass accretion onto a supermassive black hole, can involve multiple episodes. Thus thinking of jet activity as occurring within a unique brief period in the life of a galaxy is no longer valid. The most striking examples of AGNs with recurrent jet activity are the double-double radio sources, which contain two or more pairs of distinct lobes on the opposite sides of a parent optical object. On the other hand, we have now conclusive arguments that galaxy mergers and interactions are principal triggers for AGNs. Quite a number of examples of powerful radio sources hosted by galaxies with peculiar optical morphologies (tails, shells, dust-lanes, etc.) can be cited to support such a scenario. The structure and spectra of extended radio emission from radio galaxies, with sizes ranging up to a few Mpc, can provide a lot of information on the history of the central AGN activity, while the spectral and dynamical ages of these extended radio lobes could be used to constrain the time scales of recurrent AGN activity.
Galaxy populations in the 26 most massive galaxy clusters in the South Pole Telescope SPT-SZ survey

We present a study of the optical properties of the 26 most massive galaxy clusters within the South Pole Telescope Sunyaev-Zel'dovich (SPT-SZ) 2500 deg(2) survey spanning the redshift range 0.10 < z < 1.13. We measure the radial profiles, the luminosity functions (LFs), and the halo occupation numbers (HONs) using optical data of typical depth m* + 2. The stacked radial profiles are consistent with a Navarro-Frenk-White profile of concentration 2.84(-0.37)(+0.40) for the red sequence (RS) and 2.36(-0.35)(+0.38) for the total population. Stacking the data in multiple redshift bins shows slight redshift evolution in the concentration when both the total population is used, and when only RS galaxies are used (at 2.1 sigma and 2.8 sigma, respectively). The stacked LF shows a faint end slope alpha = -1.06(-0.03)(+0.04) for the total and a = -0.80(-0.03)(+0.04) for the RS population. The redshift evolution of m* is consistent with a passively evolving composite stellar population (CSP) model. Adopting the CSP model predictions, we explore the redshift evolution of the Schechter parameters alpha and phi*. We find alpha for the total population to be consistent with no evolution (0.3 sigma), and mildly significant evidence of evolution for the red galaxies (1.1-2.1 sigma). The data show that the density phi*/E-2(z) decreases with redshift, in tension with the self-similar expectation at a 2.4 sigma level for the total population. The measured HON-mass relation has a lower normalization than previous low redshift studies. Finally, our data support HON redshift evolution at a 2.1 sigma level, with clusters at higher redshift containing fewer galaxies than their low-z counterparts.
Correspondence between causality in flat Minkowski spacetime and entanglement in thermofield-double state: Hessian-geometrical study

We examine the Hessian potential that derives the flat Minkowski spacetime in $(1+1)$-dimension. The entanglement thermodynamics by the Hessian geometry enables us to obtain the entanglement entropy of a corresponding quantum state by means of holography. We find that the positivity of the entropy leads to the presence of past and future causal cones in the Minkowski spacetime. We also find that the quantum state is equivalent to the thermofield-double state, and then the entropy is proportional to the temperature. The proportionality is consistent with previous holographic works. The present Hessian geometrical approach captures that the causality in the classical side is converted into quantum entanglement inherent in the thermofield dynamics.
Employment Status and Countermeasures of Mining Engineering’s Postgraduate Employment

Based on the 2011-2016 annual report of Wuhan University of Science and Technology (WUST) graduate employment quality, postgraduate of mining engineering employment characteristics is analyzed in this paper. The result showed that the average employment rate of master degree recipients of mining engineering is 97.52% in nearly six years. The agreement/flexible employment rate and the employment industry categories total number are on rise year by year, as well as the employment ratio in Party and government organs, foreign-funded enterprises, private enterprise. Graduates have multiple regions employment with a significant correlation between locations of universities and the geographical distribution of employment. However, graduates' intention of entrance, proportion of employment geography and census register seat is consistent, and correlation between the types of their universities/specialties and sectors of employment are go down with each passing year. In practice, there are still serious contradiction between supply and requirement, and between cooperation and competition. With the analysis, it provide some guide in ideological and political education, employment guidance coordination model with multiple perspectives, and graduate quality education to the development of employment guidance.
The Demand for Money in China: A Reassessment Using the Bounds Testing Approach

This paper investigates the demand for money in China using annual data covering 1977-2006. To this end, we apply a newly-developed bounds testing technique to overcome the inherent limitations in testing for unit roots prior to testing for the existence of a level relationship between a dependent variable and a set of regressors. Our results clearly identify the long-run money demand relationship among real narrow money (or real broad money), real income, and nominal interest rates for China. The estimated long-run income elasticity and interest semi-elasticity are, respectively, 0.884 (0.915) and -0.034 (-0.002), using the real M1 (M2) equation. Our estimates of the long-run elasticity are consistent with previous studies, but they are towards the lower end of existing estimates. The results of the parameter stability test reveal that both M1 and M2 money demand are stable for China.

Predictive Value of Updating te Score Cardiovascular Risk Assessment Engine with Novel Biomarkers in a Type 2 Diabetes Population

Abstract Background and Aims: The aim of the study was to estimate the predictive value of some new biomarkers in the assessment of cardiovascular disease (CVD) risk in a type 2 diabetes (T2DM) population and to perform a correlation between the SCORE risk results and the risk profile estimated by the use of these biomarkers. Finally, we aimed to establish if the CVD risk assessment can be improved by adding the biomarkers into the SCORE risk equation. Material and Methods: In the study population the CVD risk assessment was performed using the SCORE High Risk Chart. The new individual biomarkers were: estimated glomerular filtration rate (eGFR), urinary albumin excretion (UAE) rate, albumin/creatinine ratio (UACR), cystatin C, plasminogen activator inhibitor-1 (PAI-1), high-sensitivity C-reactive protein (hs-CRP), high density lipoprotein cholesterol (HDL) and apolipoprotein B (apo-B). Results: The SCORE risk prediction model results were significantly altered by adding in the equation apo-B and HDLc values. An increase of one standard deviation of the apo-B values caused the increase of the SCORE results with 0.19 standard deviations while an increase of one standard deviation of the HDLc values decreased the SCORE results with 0.26 standard deviations. Conclusions: Advanced lipid testing, including the measurement of apo-B, provides a more comprehensive cardiac risk assessment and should be used in the development of specifically designed risk-scores for T2DM individuals.
Active and passive magnetic shielding for stray field reduction of an induction heater with axial flux

A combined active and passive shield is designed for an industrial axisymmetric induction heater for steel wire. Both the active and the passive shield should reduce the magnetic stray field of the induction heater in a given area, namely the target area. They should have low electromagnetic losses and cause a limited change of the heating induced in the workpiece. The positions as well as the currents of the active shield coils and the position and length of the passive shield are optimised. The numerical models are verified by comparing the results with measurements on the unshielded induction heater. Several passive shields (steel, copper and ferrite) and active shields are studied, resulting in a maximal field reduction of 43 dB.
Decentralized Limited-Feedback Multiuser MIMO for Temporally Correlated Channels

This paper proposes a novel multiuser (MU) multiplexing scheme for temporally correlated multiple-input, multiple-output (MIMO) channels, suitable for systems employing low-rate feedback links. A decentralized solution is obtained by the mobile receivers, which employ interference rejection combiner (IRC) linear filters and command the update of the corresponding peruser antenna transmit weights through compact feedback messages, thus avoiding explicit transmission of channel information. The proposed limited-feedback algorithm outperforms existing MU-MIMO solutions employing quantized matrices, operating at the same feedback overhead. A compensation mechanism is presented, which enables the proposed solution to operate under moderate probabilities of feedback errors, at the expense of a small downlink overhead.
The Scope of Corporate Profit Tax Consolidation: the Effect of Changing the CGT Entry Threshold

In the Russian Federation, corporate profit tax consolidation implicates rather tight restrictions on organizing a CGT. Even though earlier it was announced that the restrictions would be loosened, a moratorium has been declared on organizing consolidated groups of taxpayers since 2015. The purpose of our study is to outline existing criteria for creation CGTs and their influence on the scale of corporate profit tax consolidation in Russia as well as giving an outlook on CGTs expansion by assets and revenue. The results of organizing the CGT institution in 2012-2015 revealed their crucial significance for the Russian economy in terms of paid corporate profit tax. A model was based on the data collected from 10,000 major Russian companies describing the change of CGT share in CPT proceeds in case of lowering the CGT entry threshold. It was concluded that the relation between the CPT share and assets value or revenue differs only in case of major companies. It is expedient to specify only one criterion—either assets value or revenue—for lowering the threshold. Either choice requires a separate argumentation. Keywords—consolidated group of taxpayers, corporate profit tax, assets, revenue
Advanced Distillation Curve Analysis on Ethyl Levulinate as a Diesel Fuel Oxygenate and a Hybrid Biodiesel Fuel

Recently, a new processing technique was developed that converts the carbohydrates found in plant biomass into ethyl levulinate, which has properties making it a possible diesel fuel oxygenate additive. Additionally, the new processing technique applied to oil-containing seeds can create a biodiesel fuel at high yields, while possibly enhancing the cold flow properties that commonly plague biodiesel fuels. The first part of this two-part study focused on ethyl levulinate as a possible diesel fuel oxygenate additive, by investigating the volatility of petroleum diesel/ethyl levulinate mixtures. Volatility was measured with the advanced distillation curve (ADC) method for mixtures containing 1, 2.5, 5, 10, and 20% ethyl levulinate (v/v) and compared with unblended petroleum diesel fuel. In addition, the concentration of ethyl levulinate was tracked during the distillation for each mixture by use of the composition explicit data channel. The second part of this study investigated fatty acid−levulinate ester .
Test Platform Development of Vessel’s Power Management System Using Hardware- in-the-Loop-Simulation Technique

A PMS (Power Management System) controls vessel's power systems to improve the system efficiency and to protect a blackout condition. The PMS should be developed with considering the type and the capacity of the vessel’s power system. It is necessary to test the PMS functions developed for vessel’s safe operations under various sailing situations. Therefore, the function tests in cooperation with practical power systems are required in the PMS development. In this paper, a hardware-in-the-loop (HIL) simulator is developed for the purposes of the PMS function tests. The HIL simulator can be more cost-effective, more time-saved, easier to reproduce, and safer beyond the normal operating range than conventional off-line simulators, especially at early stages in development processes or during fault tests. Vessel's power system model is developed by using a MATLAB/ SIMULINK software and by communicating between an OPAL-RT’s OP5600 simulator. The PMS uses a Modbus communication protocol implemented using LabVIEW software. Representative tests of the PMS functions are performed to verify the validity of the proposed HIL-based test platform.
Litterfall and Leaf Area Index in the CONECOFOR Permanent Monitoring Plots

Forest canopies are more sensitive and react more promptly to abiotic and biotic disturbances than other stand structural components. Monitoring crown and canopy characteristics is therefore a crucial issue for intensive and continuous monitoring programs of forest ecosystem status. These observations formed the basis for the measurement of annual litter production and leaf area index (LAI) in the Italian permanent monitoring plots (CONECOFOR program) established within the EC-UN/ECE program "Intensive Monitoring (Level II) of Forest Ecosystems". Preliminary results after three years of observation are presented. The low value of within plot mean relative standard deviation (20.8 ± 1.9%) of litter production, which in any case never exceeded 30%, accounted for the good sampling error and accuracy of the chosen method, which seems to be accurate enough to detect changes in litter production through the years. The higher inconsistency of the amount of woody and fruits fractions over the years demonstrated the greater reliability of leaf fraction or, on the other hand, of LAI compared to total litter. Mean values of annual leaf-litter and total litter production and LAI were rather high in comparison with data reported in literature for similar stands, and reflected both a medium-high productivity and a juvenile phase in the development of the selected stands on average. Focusing on changes in litter production through the years, statistical analysis on a sub-sample of plots showed the existence of significant differences both in leaf litter and total litter production. These findings seem to attribute to the "year" factor a driving role in determining changes in litter production and LAI. Temporal intermittence in data collection, together with the shortness of the monitoring period, make it difficult to speculate or arrive at definitive conclusions on changes in litter production due to time-dependent factors. The importance of having a complete database to increase index representativeness and reliability and, on the other hand, of performing an integrated results analysis which takes into account the outcomes of other research actions, is recognized as an indispensable requirement for achieving the goals of the monitoring program.
THE RELATIONSHIP BETWEEN EMPLOYEES' SELF-MONITORING AND OCCUPATIONAL SELF-EFFICACY AND PERCEIVED TRANSFORMATIONAL LEADERSHIP 1

The topic of the present study is the relationship between transformational leadership as perceived by followers and follower characteristics such as self-monitoring and self-efficacy. Self-monitoring was hypothesized to be positively related to transformational leadership, as persons with high self-monitoring are a) sensitive to expressive behaviors of others and b) able to control their own expressive behavior. The correlations found here, however, are too small to confirm this assumption. With respect to self-efficacy, past research leads to two contradictory assumptions concerning its relationship to transformational leadership: a) Self-efficacy is negatively related to a perception of transformational leadership as "weak" employees (i.e. persons with low self-efficacy) are especially susceptible to transformational leadership or b) Self-efficacy is positively related to a perception of transformational leadership as employees with high self-efficacy see themselves as being similar to their leaders and thus tend to perceived transformational leadership in their leaders. Whereas the first hypothesis had to be rejected, the second was supported. The sample was then subdivided into groups in order to test extreme group differences. No extreme group differences could be found.
Contrast Source Inversion Method: State of Art

We discuss the problem of the reconstruction of the profile of an inhomogeneous object from scattered field data. Our starting point is the contrast source inversion method, where the unknown contrast sources and the unknown contrast are updated by an iterative minimization of a cost functional. We discuss the possibility of the presence of local minima of the nonlinear cost functional and under which conditions they can exist. Inspired by the successful implementation of the minimization of total variation and other edgepreserving algorithms in image restoration and inverse scattering, we have explored the use of these image-enhancement techniques as an extra regularization. The drawback of adding a regularization term to the cost functional is the presence of an artificial weighting parameter in the cost functional, which can only be determined through considerable numerical experimentation. Therefore, we first discuss the regularization as a multiplicative constraint and show that the weighting parameter is now completely prescribed by the error norm of the data equation and the object equation. Secondly, inspired by the edge-preserving algorithms, we introduce a new type of regularization, based on a weighted L2 total variation norm. The advantage is that the updating parameters in the contrast source inversion method can be determined explicitly, without the usual line minimization. In addition this new regularization shows excellent edge-preserving properties. Numerical experiments illustrate that the present multiplicative regularized inversion scheme is very robust, handling noisy as well as limited data very well, without the necessity of artificial regularization parameters. 190 Van den Berg and Abubakar
