Balabanova, Evgeniya; Rebrov, Aleksey; Koveshnikov, Alexei Managerial Styles in Privately Owned Domestic Organizations in Russia: Heterogeneity, Antecedents, and Organizational Implications

Drawing on a dataset consisting of 344 personal interviews, participant observations, and internal documents collected in 26 privately owned business organizations in Russia, the study aims at complementing existing research on Russian indigenous management in three ways. First, it examines the managerial styles of key individuals (i.e. owners and/or CEOs) in the case organizations. Hence, it taps into the existing heterogeneity of managerial styles, the so-called groupvergence, found in contemporary Russian organizations, and documents their idiosyncratic features, such as the transformational nature of authoritarian leadership. Second, the study explores the antecedents of the identified styles to establish what factors contribute to their emergence and thus sheds light on how the heterogeneous managerial styles in Russian organizations come into existence. Finally, the study investigates how the identified styles manifest themselves in organizations by influencing organizational goals and strategies, organizational structures, supporting mechanisms, relationships between organizational members, and reward systems. It therefore elaborates on the organizational implications of the styles and highlights the mechanisms of their sustainable diffusion to lower organizational levels in Russian organizations.
Nanosheets of CuCo2O4 As a High-Performance Electrocatalyst in Urea Oxidation

The urea oxidation reaction (UOR) is a possible solution to solve the world’s energy crisis. Fuel cells have been used in the UOR to generate hydrogen with a lower potential compared to water splitting, decreasing the costs of energy production. Urea is abundantly present in agricultural waste and in industrial and human wastewater. Besides generating hydrogen, this reaction provides a pathway to eliminate urea, which is a hazard in the environment and to people’s health. In this study, nanosheets of CuCo2O4 grown on nickel foam were synthesized as an electrocatalyst for urea oxidation to generate hydrogen as a green fuel. The synthesized electrocatalyst was characterized using X-ray diffraction, scanning electron microscopy, and X-ray photoelectron spectroscopy. The electroactivity of CuCo2O4 towards the oxidation of urea in alkaline solution was evaluated using electrochemical measurements. Nanosheets of CuCo2O4 grown on nickel foam required the potential of 1.36 V in 1 M KOH with 0.33 M urea to deliver a current density of 10 mA/cm2. The CuCo2O4 electrode was electrochemically stable for over 15 h of continuous measurements. The high catalytic activities for the hydrogen evolution reaction make the CuCo2O4 electrode a bifunctional catalyst and a promising electroactive material for hydrogen production. The two-electrode electrolyzer demanded a potential of 1.45 V, which was 260 mV less than that for the urea-free counterpart. Our study suggests that the CuCo2O4 electrode can be a promising material as an efficient UOR catalyst for fuel cells to generate hydrogen at a low cost.
NICER Discovers the Ultracompact Orbit of the Accreting Millisecond Pulsar IGR J17062–6143

We present results of recent Neutron Star Interior Composition Explorer (NICER) observations of the accreting millisecond X-ray pulsar (AMXP) IGR J17062−6143 that show that it resides in a circular, ultracompact binary with a 38-minute orbital period. NICER observed the source for ≈26 ks over a 5.3-day span in 2017 August, and again for 14 and 11 ks in 2017 October and November, respectively. A power spectral analysis of the August exposure confirms the previous detection of pulsations at 163.656 Hz in Rossi X-ray Timing Explorer (RXTE) data, and reveals phase modulation due to orbital motion of the neutron star. A coherent search for the orbital solution using the Z2 method finds a best-fitting circular orbit with a period of 2278.21 s (37.97 minutes), a projected semimajor axis of 0.00390 lt-s, and a barycentric pulsar frequency of 163.6561105 Hz. This is currently the shortest known orbital period for an AMXP. The mass function is 9.12 × 10−8 M⊙, presently the smallest known for a stellar binary. The minimum donor mass ranges from ≈0.005 to 0.007 M⊙ for a neutron star mass from 1.2 to 2 M⊙. Assuming mass transfer is driven by gravitational radiation, we find donor mass and binary inclination bounds of 0.0175–0.0155 M⊙ and 19° < i < 27. °5, where the lower and upper bounds correspond to 1.4 and 2 M⊙ neutron stars, respectively. Folding the data accounting for the orbital modulation reveals a sinusoidal profile with fractional amplitude 2.04 ± 0.11% (0.3–3.2 keV).
Deeply Integrating Visible Light and Radio Communication for Ultra-High Reliable Platooning

Platooning is one of the most promising Intelligent Transport Systems (ITS) applications, which is set to reduce the negative aspects of road traffic, by improving safety, fuel efficiency, and road efficiency. Reliable data communication is the key to such applications, besides better and smarter local sensors (e.g., radar or video). Current platooning solutions primarily build upon vehicular networking technologies such as Dedicated Short Range Communication (DSRC) and cellular V2X. However, high communication reliability is still a concern, particularly with high vehicle densities due to increasing interference levels. In order to alleviate this, the use of Visible Light Communication (VLC) instead of, or in addition to Radio Frequency (RF), has been proposed. We explore the capabilities of RF and VLC based communication protocols for platooning with a strong focus on reliability. Additionally, we propose and explore heterogeneous solutions using RF and VLC together complementing each other. By means of extensive simulations, we analyze the performance of all these solutions. Based on realistic simulation models, we show that significant improvements in terms of reliability can be achieved by integrating VLC. In this initial study, we also show that deeply integrated heterogeneous communication with RF and VLC can bring platooning one step closer to large-scale real-world deployment.
Meaning Representation for Paraphrase Detection

Abstract Meaning Representation (AMR) parsing aims at abstracting away from the syntactic realization of a sentence, and denoting only its meaning in a canonical form. As such, it is ideal for paraphrase detection, a problem in which one is required to specify whether two sentences have the same meaning. We show that na ¨ ıve use of AMR in paraphrase detection is not necessarily useful, and turn to describe a technique based on latent semantic analysis in combination with AMR parsing that signiﬁcantly advances state-of-the-art re-sults in paraphrase detection for the Microsoft Research Paraphrase Corpus. Our best results in the transductive setting are 86.6% for accuracy and 90.0% for F 1 measure.
Phase I and pharmacokinetic study of trastuzumab emtansine in Japanese patients with HER 2-positive metastatic breast cancer

Objective: Trastuzumab emtansine (T-DM1), an antibody–drug conjugate composed of the cytotoxic agent DM1 conjugated to trastuzumab via a stable thioether linker, has shown clinical activity in human epidermal growth factor receptor 2-positive metastatic breast cancer patients. This study evaluated the maximum tolerated dose, toxicity and pharmacokinetics of trastuzumab emtansine in Japanese breast cancer patients. Methods: Inoperable advanced or recurrent human epidermal growth factor receptor 2-positive breast cancer patients were administered trastuzumab emtansine intravenously at a dose of 1.8, 2.4 or 3.6 mg/kg every 3 weeks. The maximum tolerated dose was estimated using the continual reassessment method. Results: This study enrolled 10 patients whowere administered trastuzumab emtansine for a median of seven cycles. The dose-limiting toxicity was Grade 3 elevation of aspartate aminotransferase/ alanine aminotransferase at the 2.4 mg/kg dose level. The maximum tolerated dose was estimated to be 3.6 mg/kg because at the point when dose-limiting toxicity was evaluable in 10 patients, the probability of dose-limiting toxicity estimated using the continual reassessment method was closest to 25%at a dose of 3.6 mg/kg and thiswas unchanged by the results for patients enrolled after that. The most frequent adverse events were nausea, arthralgia, fever, fatigue and decreased appetite. Adverse events were generally tolerable. The maximum concentration and area under the concentration–time curve increased linearly with the dose. Conclusions: Trastuzumab emtansine up to 3.6 mg/kg was well tolerated by Japanese breast cancer patients. Although thrombocytopenia and hepatotoxicity tended to bemore severe than was seen in Japanese Journal of Clinical Oncology, 2015, 45(1) 12–18 doi: 10.1093/jjco/hyu160 Advance Access Publication Date: 20 October 2014
Treat Alzheimer's disease by traditional Chinese medicine?

Upregulated phosphodiesterase 4D (PDE4D) disrupts the regulation of calcium ion channel in the central nerve system, and hence it is considered as one of the causes of Alzheimer's disease. We employed structure-based drug design techniques and the world's largest traditional Chinese medicine (TCM) database for identifying potential TCM-based PDE4D inhibitors. We then applied multiple linear regression (MLR) and support vector machine (SVM) for quantitative structure–activity relationship model, as well as for molecular dynamics simulation analysis. Screening results suggested that metal cations, Zn2+ and Mg2+, played key roles in mediating stable protein–ligand interactions with the ligand-binding residues, Asp367 and Asp484. In addition, each ligand was shown to interfere with the active residue His326 that suggested inhibitory effects. The MLR and SVM prediction models further implied the PDE4D inhibitory effect of each TCM compound. The molecular simulation further suggested the binding stability of each compound in the PDE4D binding site. We identified three TCM compounds, such as mumefural, 2-O-feruloyl tartaric acid and kainic acid, as potential PDE4D inhibitors. In addition, we further identified the key interaction features associated with the protein–ligand-binding stabilities.
Studi Pendahuluan Epidemiologi Kontaminasi Aflatoksin B1 pada Pakan Ayam

Aflatoksin merupakan salah satu jenis mikotoksin yang paling berbahaya dibandingkan dengan mikotoksin lainnya dan banyak mendapat perhatian, karena dampaknya dapat merugikan kesehatan manusia dan ternak. Meskipun kandungan aflatoksin pada pakan terbilang rendah, namun apabila diberikan kepada ternak dalam jangka waktu lama akan mengakibatkan kerugian ekonomi karena pertumbuhan (kinerja) ternak menjadi lambat, menimbulkan efek toksik yang kronis, menurunkan kekebalan terhadap penyakit infeksius dan menyebabkan timbulnya residu pada produk ternak. Penelitian ini bertujuan untuk memperoleh informasi dasar studi epidemiologi kontaminasi aflatoksin pada pakan unggas. Sebanyak 329 sampel pakan unggas dikoleksi dari 22 peternakan ayam pedaging dan 11 peternakan ayam petelur di Kabupaten Bogor dan masingmasing terdiri atas 219 dan 110 sampel. Analisis aflatoksin B1 (AFB1) dalam sampel pakan dilakukan menggunakan metode ELISA yang telah dikembangkan di Balai Besar Penelitian Veteriner (BBLitvet) Bogor. Kejadian sampel positif aflatoksin dalam pakan ayam pedaging dan petelur masing-masing 91 dan 82,73%. Kisaran rata-rata konsentrasi AFB1 pada sampel pakan dari peternakan ayam pedaging berkisar antara 0,23-18,30 ppb (n = 22) dan dari peternakan ayam petelur berkisar antara 0,30-23,30 ppb (n = 11). Rata-rata kontaminasi AFB1 pakan ayam pedaging 3,94±0,318 ppb dan pada pakan ayam petelur 7,47±0,686 ppb masih berada di bawah ketentuan regulasi SNI aflatoksin pada pakan. Akan tetapi hasil analisis pakan ayam petelur menunjukkan bahwa 2% dari sampel yang dikoleksi terkontaminasi AFB1 dengan nilai cemaran lebih tinggi dari Prosiding Seminar Nasional Teknologi Peternakan dan Veteriner 2015 526 regulasi SNI aflatoksin untuk pakan ayam petelur (≥50 ppb). Disimpulkan bahwa kejadian cemaran AFB1 pada pakan ayam petelur dan pedaging tinggi, tetapi tingkat kontaminasinya relatif rendah.
On-line Television Stream Classification by Genre Karlis

Convolutional neural networks (CNNs) have become the state-of-the-art solution for image classification and other related problems. This paper investigates the use of CNNs’ features for on-line television stream classification by genre of the programme. As most existing offline classification solutions propose the use of low level audio-visual video descriptors, this paper compares the precision achieved by simple structure multi-layer perceptrons (MLP) and long short-term memory (LSTM) recurrent neural networks (RNNs) using either low level visual and audial descriptors or activations of InceptionV3 CNN’s global pooling layer as features. The best real-time classification accuracy on evaluation data set of 71,6% was achieved by an LSTM RNN of CNN features, supporting the use of CNNs for television genre classification.
Can Rhythmical Auditory Stimulation Alter Gait Pattern in Children with Asperger Syndrome

The aims of this study were to evaluate the gait abnormalities in children with Asperger syndrome (AS) and to investigate the effectiveness of rhythmical auditory stimulation (RAS) on gait training in children with this condition. Five children with AS (mean age: 8.5 ± 2.0 years) and 6 children with normal development (mean age: 9.5 ± 2.0 years) participated in this study. The participants were asked to walk on a treadmill under each of the following conditions conducted in sequence: (1) walk at a comfortable speed with no RAS (baseline), (2) walk at a comfortable speed accompanied by RAS (sound-on condition), and (3) walk again at a comfortable speed with no RAS (sound-off condition). The temporal and kinematic gait parameters of the walking in each condition were recorded with a VICON 370 system. No significant differences were found among the baseline, sound-on, and sound-off gait parameters in either group. The children with AS rotated their pelvis more during walking than the control group did at baseline (p=0.018) and during the sound-on (p=0.011) condition. Moreover, the control group spent less time in the doubleleg supporting position in the sound-on and subsequent sound-off condition than the AS group did. No statistically significant differences were found between the two groups in all other gait parameters (i.e., step length, step width, step height, hip and knee joint angles at mid-stance phase of gait) in the three testing conditions. The children with AS demonstrated excessive pelvic rotation during walking when compared to children with normal development. A short period of gait training with RAS might not be able to improve the walking pattern in children with AS.
Gauging the Vertical Specialization in EU Trade 1 IULIA

The purpose of this paper is threefold. First, we review the mechanisms and determinants of vertical specialization (VS), as this has gradually become the dominant characteristic of international trade. Second, we underline that there is a rich literature regarding VS in EU trade, at aggregate and individual levels and research is advancing together with the instruments used to measure trade in value added. Third, our investigation brings to the forefront a classification of EU countries according to their GVC participation index, taking into consideration both upstream and downstream links. As a conclusion, the VS analyses help us better understand the interconnectedness among countries and industries by means of foreign direct investment, trade, labour migration and technology transfer. Key-Words: international trade, vertical specialization (VS), foreign direct investment (FDI), global value chains (GVC), global production networks, trade in value-added (TiVA), participation index, upstream links, downstream links. JEL Classification: E20, F14, F15, F60, F62, O14. 1. Vertical specialization – concept, mechanisms and determinants The concept of vertical specialization (VS) was suggested for the first time by Balassa in 1967 in relationship with the process of joint fragmentation and globalization of production (Leitner, Stehrer, 2014). Nonetheless it became an established notion in the economic literature only in the 1990s with the meaning of foreign value added content of gross exports. Fragmentation or vertical disintegration (Krugman, 1995, p. 334, Feenstra, 1998, p. 35) or “production staging” (Fally, 2012) is linked to imported inputs embodied in goods (either final or unfinished) that are exported, which underlines the “multiple-border-crossing” inherent feature of trade (Hummels et al., 2001, p. 77). Otherwise stated, VS means “slicing up the value chain” in order to “produce a good in a number of stages in a number of locations, adding a little bit of value at each stage” (Krugman, 1995, p. 334). Box 1 offers an overview of the VS and its main forms. 1 The present paper is based on the author’s researches included in the study “EU: Reconfiguring the Trade Policy after the Treaty of Lisbon. Romania’s Position”, IWE, Romanian Academy. It will also be presented at the international conference organized by the IWE in December 2014.
Determination of Soil Organic Carbon Levels Using Near Infrared Spectroscopy ( NIRS ) in Saline Soils

Due to the global climate change, salinity is in arid and semi–arid climates a major problem for the soils. In this connection it is very important to determine the organic carbon content in saline soils. This is aimed at the study that prediction of the organic carbon content in saline soils using NIRS and to evaluate the success of near infrared reflection spectroscopy (NIRS). NIRS device of 116 soil samples from different levels of soil salinity were collected between (350–2500 nm). Partial Least Square (PLS) regression analysis was used to conclude between the results obtained from the reflection values and traditional analyses methods at the laboratoary. NIRS calibrations were developed with modified partial least square regression and tested with independent validation samples. The best equations were obtained with the first derivative of the spectra without scatter corrections. The results obtained from the experiment concluded that soils of resource area texture, organic matter, CaCO3 and salinity are affects on the reflection values. Good predictions were obtained for organic carbon contents in salt effected soils. According to the results obtained from the study, NIRS could be used as a practical and economic technique to predict organic carbon contents in salt effected soils.
A Low Profile Dual Polarized Slot Coupled Patch Antenna

Abstract—A low profile, dual polarized, slot coupled patch antenna is designed and developed in this paper. The antenna has a measured bandwidth of 17.2% for return loss > 15 dB and pair ports isolation >23 dB. The gain of the antenna is over 10 dBi and the half power beam widths (HPBW) of the antenna are 80±3o in the horizontal plane and 39±2o in the vertical plane. The cross polarization discrimination (XPD) is less than 20 dB in HPBW. Within the operating band, the performances of good impedance match, high ports isolation, low cross polarization, and stable radiation patterns are achieved.
Improvement in Nutritional Quality of Shrimp Meal with Autoclave and Chemical Treatments: an in vitro Study

The present study was conducted to improve the nutritional quality of shrimp meal (SM) comprising of heads with hulls of black tiger shrimp (Penaeus monodon) waste by autoclaving and chemical treatments. The sun-dried SM was divided into 5 treatment groups, such as 1) control (untreated), 2) autoclaved (autoclaved at 121°C for 10 min), 3) NaOH (treated with 3% NaOH), 4) HCl (treated with 3% HCl) and 5) formic acid (treated with 3% formic acid) groups. After treatment, they were ground to pass through 1.0 mm mesh screen and then used for analyses of chemical composition and in vitro dry matter (DM) and CP digestibilities. Data were subjected to one-way ANOVA and differences among treatment means (P<0.05) were distinguished with Tukey's test. There were no significant difference in chemical composition and in vitro DM and CP digestibilities between control and autoclaved groups, except ether extract level (P<0.05), suggesting that autoclaving affected the nutritional quality of SM little. NaOH group exhibited significantly decreased CP level and in vitro DM digestibility, increased crude ash (CA) level and unchanged in vitro CP digestibility, comparing with control group. These results suggest that NaOH treatment affected the nutritional quality of SM adversely. HCl and formic acids groups showed significantly increased CP level and in vitro digestibilities of DM and CP, and decreased CA level, showing that acid treatment can improve nutritional quality of SM: formic acid treatment may be more effective because of the greater values in CP level and digestibilities and decreased crude fibre level which was not observed in HCl group (P<0.05). The results obtained here suggest acid, especially formic acid, treatment is promising to improve the nutritional quality of SM but autoclaving and NaOH treatments.
Extreme HBL behavior of Markarian 501 during 2012

Aims. We aim to characterize the multiwavelength emission from Markarian 501 (Mrk 501), quantify the energy-dependent variability, study the potential multiband correlations, and describe the temporal evolution of the broadband emission within leptonic theoretical scenarios. Methods. We organized a multiwavelength campaign to take place between March and July of 2012. Excellent temporal coverage was obtained with more than 25 instruments, including the MAGIC, FACT and VERITAS Cherenkov telescopes, the instruments on board the Swift and Fermi spacecraft, and the telescopes operated by the GASP-WEBT collaboration. Results. Mrk 501 showed a very high energy (VHE) gamma-ray flux above 0.2 TeV of ∼0.5 times the Crab Nebula flux (CU) for most of the campaign. The highest activity occurred on 2012 June 9, when the VHE flux was ∼3 CU, and the peak of the high-energy spectral component was found to be at ∼2 TeV. Both the X-ray and VHE gamma-ray spectral slopes were measured to be extremely hard, with spectral indices < 2 during most of the observing campaign, regardless of the X-ray and VHE flux. This study reports the hardest Mrk 501 VHE spectra measured to date. The fractional variability was found to increase with energy, with the highest variability occurring at VHE. Using the complete data set, we found correlation between the X-ray and VHE bands; however, if the June 9 flare is excluded, the correlation disappears (significance < 3σ) despite the existence of substantial variability in the X-ray and VHE bands throughout the campaign. Conclusions. The unprecedentedly hard X-ray and VHE spectra measured imply that their low- and high-energy components peaked above 5 keV and 0.5 TeV, respectively, during a large fraction of the observing campaign, and hence that Mrk 501 behaved like an extreme high-frequency-peaked blazar (EHBL) throughout the 2012 observing season. This suggests that being an EHBL may not be a permanent characteristic of a blazar, but rather a state which may change over time. The data set acquired shows that the broadband spectral energy distribution (SED) of Mrk 501, and its transient evolution, is very complex, requiring, within the framework of synchrotron self-Compton (SSC) models, various emission regions for a satisfactory description. Nevertheless the one-zone SSC scenario can successfully describe the segments of the SED where most energy is emitted, with a significant correlation between the electron energy density and the VHE gamma-ray activity, suggesting that most of the variability may be explained by the injection of high-energy electrons. The one-zone SSC scenario used reproduces the behavior seen between the measured X-ray and VHE gamma-ray fluxes, and predicts that the correlation becomes stronger with increasing energy of the X-rays.
