Research on Robust Model for Web Service Selection
Authors: Yanxi Wei , Fan Yu , Xing Ma , Haige Yu , Wenhui Yang
Published: June 2018

Most existing service quality models use defined Quality of Service parameters for service selection.Since a large number of uncertainties exist, the QoS performance indicators in the runtime of the composite services obtained through the model and method based on the determined QoS will be worse even beyond the range acceptable to the users. Web services can solve this problem and become the most reasonable solution in the current application environment. Web services can solve this problem and become the most reasonable solution in the current application environment. In the process of actual service delivery, the key to the failure of the service composition to meet the requirements is caused by uncertain factors. In order to solve the above problems, this paper first proposes a local optimal selection model based on uncertain QoS. The Web service selection method based on uncertain QoS has been progressing in recent years. Second, in order to reduce the time spent on selection, a redundant service selection result is given. The experimental results on the data set show that the proposed model and method can effectively select more robust services for users.

With the maturity of UAV technology, especially the cost of the four rotor unmanned aerial vehicle is decreasing, the unmanned aerial vehicle (UAV) will be a trend in the future. At the same time, because ZigBee has the characteristics of low cost, low speed and short transmission distance, we use ZigBee to achieve the transmission of image files between UAV and ground receiving system computers. This paper introduces the system design and software program module hardware node design, the first use of ZigBee wireless network as a data link, and then collected by the UAV to the ground of the computer image transmission, in the process of transmission by subcontracting, merging, stop and wait Agreement to ensure the correctness of data transmission right. Through experimental test, the correct transmission of image files between UAV and ground end computer can be realized when the image data is less than 1024K bytes.
Research on the Key Technology of Survey Measurement Image Based on UAV
Authors: Li Ding , Jiao Chong
Published: June 2018

With the development of computer technology, especially the emergence of high resolution image sensor, aerial photogrammetry has played an important role in geological survey. Traditional aerial measurements are carried out by manned large aircraft, with a large volume of measured information and a wide range of shots. This method is suitable for large area operation, which is high and expensive for hardware site. UAV air measurement systems are usually used for small area measurements. The UAV is small and fluctuates greatly during flight, the collection of the data and images are not accurate enough. This paper has obtained the accurate measurement of image by studying the image fast matching theory, which has practical significance in the actual mapping and has higher research value.
Non-antibiotics, Efflux Pumps and Drug Resistance of Gram-negative Rods
Authors: LAUDY AGNIESZKA EWA
Published: June 2018

Non-antibiotic medicinal products consist of drugs with diverse activity against bacteria. Many non-antibiotics demonstrate direct anti-bacterial activity against Gram-positive cocci. The activity observed against Gram-negative rods is much lower and non-antibiotics primarily from the following groups: non-steroidal anti-inflammatory drugs, cardiovascular and antidepressant medicinal products demonstrate this activity. It has been shown that the low activity of some non-antibiotics or the absence of activity against Gram-negative rods is related, among other things, to the extrusion of these compounds from bacterial cells by multi-drug resistance efflux pumps. Substrates for the resistance-nodulation-division efflux systems include the following non-antibiotics: salicylate, diclofenac, ibuprofen, mefenamic acid, naproxen, amitriptyline, alendronate sodium, nicergoline, and ticlopidine. In addition, interactions between non-antibiotics and multi-drug resistance efflux pumps have been observed. It has also been revealed that depending on the concentration, salicylate induces expression of multi-drug resistance efflux pumps in Escherichia coli, Salmonella enterica subsp. enterica serotype Typhimurium, and Burkholderia cenocepacia. However, salicylate does not affect the expression of the resistance-nodulation-division efflux systems in Stenotrophomonas maltophilia and Acinetobacter baumannii. Most importantly, there were no effects of medicinal products containing some non-antibiotic active substances, except salicylate, as substrates of multi-drug resistance efflux pumps, on the induction of Gram-negative rod resistance to quinolones.

Published: June 2018

Background: There is little evidence in the literature on the association between methylphenidate treatment and psychotic symptoms in children and adolescents with attention-deficit/hyperactivity disorder (ADHD).

Objective: We examine the occurrence of psychotic symptoms during methylphenidate treatment of children and adolescents with ADHD. The data arise from our two Cochrane systematic reviews on methylphenidate, reported elsewhere.

Methods: Electronic databases were searched up to January 2016 (for observational studies) and March 2017 (for randomized trials). We summarized data as risk ratios and pooled prevalences. Trial Sequential Analysis was used to control for random errors. We assessed the risk of bias and the quality of evidence according to Cochrane guidelines.

Results: Ten randomized trials (1103 participants), 17 non-randomized studies (76,237 participants) and 12 patient reports or series (18 patients) were identified. In the randomized trials, there was no significant difference in the risk of developing psychotic symptoms [10 of 654 (pooled prevalence, 2.5%) methylphenidate versus 1 of 508 (pooled prevalence, 1.7%) placebo patients; risk ratio, 2.07; 95% confidence interval, 0.58 to 7.35]. Nine of 10 trials had a high risk of bias, and according to the Trial Sequential Analysis, the required information size was not achieved, that is, the meta-analysis was considerably underpowered. There were 873 instances of psychotic symptoms in the non-randomized studies among 55,603 participants (pooled prevalence, 1.2%; 95% confidence interval, 0.7 to 2.4). In the comparative cohort study, methylphenidate significantly increased the risk for any psychotic disorder by 36% (risk ratio, 1.36; 95% confidence interval, 1.17 to 1.57). The overall risk of bias was rated as critical for this study.

Conclusions: Because of sparse data and low quality of evidence, we cannot confirm or refute whether methylphenidate increases the risk of psychotic symptoms in children and adolescents with ADHD. This possible adverse event may affect 1.1% to 2.5%, and physicians, patients and caregivers should be aware of this to ensure proper treatment in case of occurrence during methylphenidate treatment.
A BAYESIAN INFERENCE OF MULTIPLE STRUCTURAL BREAKS IN MEAN AND ERROR VARIANCE IN PANELAR (1) MODEL
Authors: Agiwal Varun , Kumar Jitendra , Shangodoyin Dahud Kehinde
Published: June 2018

This paper explores the effect of multiple structural breaks to estimate the parameters and test the unit root hypothesis in panel data time series model under Bayesian perspective. These breaks are present in both mean and error variance at the same time point. We obtain Bayes estimates for different loss function using conditional posterior distribution, which is not coming in a closed form, and this is approximately explained by Gibbs sampling. For hypothesis testing, posterior odds ratio is calculated and solved via Monte Carlo Integration. The proposed methodology is illustrated with numerical examples.
JOINT RESPONSE PROPENSITY AND CALIBRATION METHOD
Authors: Laaksonen Seppo , Hämäläinen Auli
Published: June 2018

This paper examines the chain of weights, beginning with the basic sampling weights for the respondents. These were then converted to reweights to reduce the bias due to missing quantities. If micro auxiliary variables are available for a gross sample, we suggest taking advantage first of the response propensity weights, and then of the calibrated weights with macro (aggregate) auxiliary variables. We also examined the calibration methodology that starts from the basic weights. Simulated data based on a real survey were used for comparison. The sampling design used was stratified simple random sampling, but the same methodology works for multi-stage sampling as well. Eight indicators were examined and estimated. We found differences in the performance of the reweighting methods. However, the main conclusion was that the response propensity weights are the best starting weights for calibration, since the auxiliary variables can be more completely exploited in this case. We also tested problems of calibration methods, since some weights may lead to unacceptable weights, such as below 1 or even negative.
Long‐term Cropping Effects on Partitioning of Water Flow and Nitrate Loss between Surface Runoff and Tile Drainage
Authors: Woodley A. L. , Drury C. F. , Reynolds W. D. , Tan C. S , Yang X. M. , Oloya T. O.
Published: June 2018

Surface runoff and tile drainage are the main pathways for water movement and entry of agricultural nitrate into water resources. The objective of this 5‐yr study was to characterize the partitioning of water flow and nitrate loss between these pathways for a humid‐temperate Brookston clay loam soil under 54 to 59 yr of consistent cropping and fertilization. Cropping treatments included monoculture corn (Zea mays L., MC), continuous bluegrass (Poa pratensis L.) sod (CS), and a corn–oat–alfalfa (Medicago sativa L.)–alfalfa rotation (RC–RO–RA1–RA2). Fertilization treatments included annual fertilizer addition (F) and no fertilizer addition (NF). Tile drainage and surface runoff occurred primarily during the nongrowing season (November–April), and they were highly correlated with the mean saturated hydraulic conductivity of the near‐surface soil profile. Tile drainage accounted for 69 to 90% of cumulative water flow and 79 to 96% of cumulative nitrate loss from fertilized rotation and CS, whereas surface runoff accounted for the majority of the nitrate losses in MC (i.e., 75–93% of water flow and 65–96% of nitrate loss). Cumulative nitrate losses were highest in the RC‐F (152 kg N ha−1), RC‐NF (101 kg N ha−1), RA2‐F (121 kg N ha−1), and RA2‐NF (75 kg N ha−1) plots, and these high losses are attributed to N mineralization from the plowed alfalfa and fertilization (if applicable). Fertilization increased cumulative nitrate loss in tile drainage from all treatments, whereas no fertilization increased cumulative nitrate loss in surface runoff from the rotation. Cropping system and fertilization on clay loam soil changed how water flow and nitrate loss were partitioned between tile drainage and surface runoff.

Core Ideas

Water partitioning is highly correlated with mean saturated hydraulic conductivity.

Tile drainage was the main pathway of water flow and nitrate loss in rotation plots.

Surface runoff was the main pathway of water flow and nitrate loss in monoculture corn.

Fertilization increased nitrate loss and water flow through tile drainage.

Average nitrate loss was 36% greater in the rotation plots versus monoculture corn.

Special aspects of using hybrid financial tools for project risk management in Ukraine
Authors: Mishchenko Volodymyr , Naumenkova Svitlana , Ivanov Viktor , Tishchenko Ievgen
Published: June 2018

The relevance of the article is due to the need of using non-traditional tools for capital raising and hedging financial risks in Ukrainian conditions that allow investors to protect themselves against possible losses during the entire life cycle of the investment project. The study is based on the National Bank of Ukraine statistical data, data of Ukrainian commercial banks, as well as on the authors’ calculations based on empirical and economic-statistical methods. According to international practices, hybrid financial instruments were classified and the special aspects of their use in Ukraine were studied to manage the risks of project financing. Specific features of using the structured bonds for financing investment projects are determined based on the synthetic securitization scheme. The experience of Ukrainian banks was analyzed and the necessity to use financial instruments such as guarantees and letters of credit in risk management of project financing was substantiated. It has been established that forward contracts, currency swaps and over-the-counter currency options are the most acceptable instruments for hedging foreign exchange risks of project financing. Further studies of the problem should include the need for legislative regulation of using hybrid financial instruments, as well as methodological and regulatory support for the risk management of project financing at all stages of the investment project implementation.
New Age elements in the Clamp’s manga X
Authors: Castelli-Olvera Sarahi Isuki
Published: June 2018

In this article, we start from the consideration that manga X, created by the collective CLAMP between 1994 and2003, and published in Mexico by Editorial Vid between 2002 and 2005, is a story whose overarching principle corresponds to the various elements of the New Age. We base this on the following assumptions: first in this manga, the sephirotic tree, the B.O.T.A. tarot and the aspects of Enochian magic, typical of western esoterism, are present iconographically. Second, Kamui, the subject of the story, represents God, so that his actions determine the entire narrative; besides, it has a twin star (Fuma), which fulfills the function of being its complementary opposite. Finally, the apocalypse is detonated by the well-being of the Earth, which arises as an organism with its own life and is intended to survive the destruction of humanity. We carry out this analysis taking up the notion of an overarching principle, as well as the importance of the source, present in the historical method. In addition to the above, we use the paradigm of indicial inferences proposed by Carlo Ginzburg, the elements of structural analysis of Helena Beristain’s story and the notion of postmodernity introduced by Fredrick Jameson. The primary sources would be the 18 volumes of X published in Mexico.
Resident and Attending Physicians� Perceptions of Patient Access to Provider Notes: Comparison of Perceptions Prior to Pilot Implementation (Preprint)
Authors: Nandiwada Deepa Rani , Fischer Gary S , Updike Glenn , Conroy Margaret B
Published: June 2018

BACKGROUND

As electronic health records have become a more integral part of a physician’s daily life, new electronic health record tools will continue to be rolled out to trainees. Patient access to provider notes is becoming a more widespread practice because this has been shown to increase patient empowerment.

OBJECTIVE

In this analysis, we compared differences between resident and attending physicians’ perceptions prior to implementation of patient access to provider notes to facilitate optimal use of electronic health record features and as a potential for patient empowerment.

METHODS

This was a single-site study within an academic internal medicine program. Prior to implementation of patient access to provider notes, we surveyed resident and attending physicians to assess differences in perceptions of this new electronic health record tool using an open access survey provided by OpenNotes.

RESULTS

We surveyed 37% (20/54 total) of resident physicians and obtained a 100% response rate and 72% (31/44 total) of attending physicians. Similarities between the groups included concerns about documenting sensitive topics and anticipation of improved patient engagement. Compared with attending physicians, resident physicians were more concerned about litigation, discussing weight, offending patients, and communicated less overall with patients through electronic health record.

CONCLUSIONS

Patient access to provider notes has the potential to empower patients but concerns of the resident physicians need to be validated and addressed prior to its utilization.

Published: June 2018

Methylation of p16 and p14 genes is a common event in colorectal cancers; however, their exact role in the prediction of patients? outcome is unclear. We conducted this retrospective study to evaluate their potential predictive and/or prognostic roles. Methylation-specific PCR was used to examine the methylation status of p16 and p14 in pretherapeutic and preoperative biopsy specimens of 60 patients with locally advanced rectal cancer. The methylation status of the examined genes did not affect the response to preoperative chemoradiotherapy (CRT), recurrence rate and overall survival. However, patients with a simultaneous presence of either p16 or p14 methylation and high vascular endothelial growth factor (VEGF) expression showed a significantly worse response to CRT (p=0.005 and p=0.038, respectively). Moreover, patients with both p16 methylation and high VEGF expression had significantly shorter overall survival (p=0.010), while no such association was found in patients with p14 methylation and high VEGF expression. On the other hand, a subgroup of patients with p16 methylation and low VEGF and high epidermal growth factor receptor (EGFR) expression showed a significantly better response to CRT (p=0.024). The obtained results point to the importance of p16 and p14 methylation analyses in combination with VEGF and EGFR expression, aimed at better predicting treatment response and patient outcome.

Reforma, missão e política: dimensões esquecidas
Authors: Schaper Valério Guilherme , Zwetsch Roberto Ervino
Published: June 2018

O presente artigo tem por objetivo refletir duas questões atuais na teologia desde o ponto de vista da teologia da Reforma, cujos 500 anos foram celebrados em 2017. O desafio é retomar algumas das balizas do movimento que transformou a igreja e o mundo no início do século XVI, desde uma perspectiva crítica e prospectiva. À primeira vista, os dois temas – missão e política – não parecem se apresentar no fulcro dos debates que o movimento suscitou. Mas em nossa abordagem vamos tentar demonstrar a pertinência de ambos para um debate justo sobre a “dimensão política da fé cristã”. E vamos fazê-lo acessando o que se poderia chamar de subterrâneos da experiência da vida de fé e da experiência religiosa. O artigo vai propor o tema em três tópicos: um primeiro sobre o sentido do movimento da Reforma e suas consequências para igreja e sociedade; na sequência debater a possível ausência da ideia de missão na teologia da Reforma, especialmente em Lutero; por fim, a pergunta pela política como espaço de incidência da fé e sem a qual o amor proclamado a partir da fé se torna discurso inócuo.

Published: June 2018

Ce texte est issu d'une conférence donnée au CRÉDIC à l'occasion de son 38ème Colloque à Maredret France en août 2017. Son but est d'offrir au lecteur la réflexion sur la proclamation de Dieu dans la perspective latino-américaine. La réflexion s'exprime en trois points : les origines, les lignes principales et la réception de la Théologie de la Libération. De cette façon, on peut voir le chemin pris. Tout d'abord un souvenir historique de la naissance de la réflexion théologique sortie d'une réalité ecclésiale, sociale et politique difficile ; dans un second moment, les grandes lignes de cette réflexion théologique issue de sa méthode, voir-juger-agir, sont présentées. Enfin, la réception de cette théologie à l'intérieur et à l'extérieur de l'Amérique latine est présentée. De cette manière, nous avons une vision large, claire et martyrologique de l'expression de l'expérience de foi de l'Église latino-américaine.

Los derechos humanos y los sociales, susceptibles de permanente reinvención: una mirada innovadora desde el presente en sintonía con el pasado.
Authors: Lacalzada-de-Mateo María José
Published: June 2018

Es conocido que el Trabajo social defiende la autonomía de la persona y favorece la inclusión en el medio, mejorando sus oportunidades. La palabra “innovación” hoy adquiere protagonismo en la intervención, en particular, y para la estructuración de los Estados y las relaciones políticas, en general. Los Derechos Humanos y su derivación en sociales arrostran tales dificultades, tales presiones estructurales, que quienes los defienden han de mantener una actitud que parezca innovadora. Es la clave con la que se presupone credibilidad dentro del culto a lo inmediato que nos envuelve hoy. Defender los derechos de las personas es recoger un testigo humanizador que toma por referente la dignidad humana. Siempre que se ha tenido esta actitud han mejorado las relaciones en sociedad. Está en el fundamento de los Estados de Bienestar, estableciendo reglas que han mejorado el acceso al reparto de las riquezas, objetivando normas y derechos en el espacio público. Si nos situamos historiográficamente en el siglo XIX encontraremos una perspectiva que fue reformadora e innovadora en el pasado y que mantiene su fuerza revolucionaria en el presente: ajustar el ángulo de visión desde la dignidad y sentido integral de la persona humana. Discurrir así, tiene capacidad para mejorar las intervenciones y para objetivar normas para hacer viable la justicia social y con ello orientar la práctica del Trabajo Social hacia la promoción de las personas y colectivos más vulnerables de la sociedad. Llevaremos la atención sobre esta forma de discurso que recoge cierto legado humanista que encamina a construir un mundo más sostenible.

Recently, this method has been applied in the Black–Scholes framework to European vanilla barrier options with constant and time-dependent parameters or barriers and to geometric Asian barrier options with a fixed strike price. The greater efficiency of SABO with respect to classical finite difference methods is clearly evident in numerical simulations. For the first time, a user-friendly MATLAB® code is made available here.
The Role of Immune Checkpoint Inhibitors in Classical Hodgkin Lymphoma
Authors: Meti Nicholas , Esfahani Khashayar , Johnson Nathalie
Published: June 2018

Hodgkin Lymphoma (HL) is a unique disease entity both in its pathology and the young patient population that it primarily affects. Although cure rates are high, survivorship can be linked with significant long-term morbidity associated with both chemotherapy and radiotherapy. The most significant recent advances have been with the use of the anti-CD30-drug conjugated antibody brentuximab vedotin (BV) and inhibitors of program death 1 (PD-1). HL is genetically wired to up-regulate program death ligand 1 (PD-L1) in >95% of cases, creating a state of so-called “T cell exhaustion”, which can be reversed with immune checkpoint-inhibitor blockade. The overall and complete response rates to PD-1 inhibitors in patients with relapsed or refractory HL are 70% and 20%, respectively, with a long median duration of response of ~16 months. In fact, PD-1 inhibitors can benefit a wide spectrum of relapsed HL patients, including some who have “progressive disease” by strict response criteria. We review the biology of HL, with a focus on the immune micro-environment and mechanisms of immune evasion. We also provide the rationale supporting the use of PD-1 inhibitors in HL and highlight some of the challenges of monitoring disease response in patients treated with this immunotherapy.

Hispanic adolescent girls with normal BMI frequently have high body fat %. Without knowledge of body fat content and distribution, their risk for metabolic complications is unknown. We measured metabolic risk indicators and abdominal fat distribution in post-pubertal Hispanic adolescent girls with Normal BMI (N-BMI: BMI < 85th percentile) and compared these indicators between girls with Normal BMI and High Fat content (N-BMI-HF: body fat ≥ 27%; n = 15) and Normal BMI and Normal Fat content (N-BMI-NF: body fat < 27%; n = 8). Plasma concentrations of glucose, insulin, adiponectin, leptin and Hs-CRP were determined. Insulin resistance was calculated using an oral glucose tolerance test. Body fat % was measured by DXA and subcutaneous, visceral and hepatic fat by MRI/MRS. The N-BMI-HF girls had increased abdominal and hepatic fat content and increased insulin resistance, plasma leptin and Hs-CRP concentrations (p < 0.05) as compared to their N-BMI-NF counterparts. In N-BMI girls, insulin resistance, plasma insulin and leptin correlated with BMI and body fat % (p < 0.05). This research confirms the necessity of the development of BMI and body fat % cut-off criteria per sex, age and racial/ethnic group based on metabolic risk factors to optimize the effectiveness of metabolic risk screening procedures.
Trophic Diversity of Plankton in the Epipelagic and Mesopelagic Layers of the Tropical and Equatorial Atlantic Determined with Stable Isotopes
Authors: Bode Antonio , Hernández-León Santiago
Published: June 2018

Plankton living in the deep ocean either migrate to the surface to feed or feed in situ on other organisms and detritus. Planktonic communities in the upper 800 m of the tropical and equatorial Atlantic were studied using the natural abundance of stable carbon and nitrogen isotopes to identify their food sources and trophic diversity. Seston and zooplankton (>200 µm) samples were collected with Niskin bottles and MOCNESS nets, respectively, in the epipelagic (0–200 m), upper mesopelagic (200–500 m), and lower mesopelagic layers (500–800 m) at 11 stations. Food sources for plankton in the productive zone influenced by the NW African upwelling and the Canary Current were different from those in the oligotrophic tropical and equatorial zones. In the latter, zooplankton collected during the night in the mesopelagic layers was enriched in heavy nitrogen isotopes relative to day samples, supporting the active migration of organisms from deep layers. Isotopic niches showed also zonal differences in size (largest in the north), mean trophic diversity (largest in the tropical zone), food sources, and the number of trophic levels (largest in the equatorial zone). The observed changes in niche size and overlap (up to 71% between the mesopelagic layers but <50% between the epipelagic and upper mesopelagic layers) support the prevalence of in situ feeding at deep layers in tropical and equatorial zooplankton.

The dynamic nature of engineered nanoparticle (ENP) aggregation behavior and kinetics are of paramount importance in the field of toxicological and environmental nanotechnology. The Taguchi orthogonal array (OA) L27(313) matrix based on a fractional factorials design was applied to systematically evaluate the contribution and significance of water chemistry parameters (pH, temperature, electrolyte, natural organic matter (NOM), content and type) and their interactions in the aggregation behavior of zinc oxide nanoparticles (ZnO NPs). The NPs were dispersed into the solution using a probe-sonicator cell crusher (Bio-safer, 1200-90, Nanjing, China). The data were obtained from UV–Vis spectroscopy (Optizen 2120 UV, Mecasys, Daejeon, Korea), Fourier Transform Infrared Spectrometery (FT-IR 4700, spectroscopy, a JASCO Analytical Instruments, Easton, Pennsylvania, USA) and particle electrophoresis (NanoZS, Zetasizer, Malvern Instruments Ltd., Worcestershire, UK). The dataset revealed that Taguchi OA matrix is an efficient approach to study the main and interactive effects of environmental parameters on the aggregation of ZnO NPs. In addition, the aggregation profile of ZnO NPs was significantly influenced by divalent cations and NOM. The result of the FT–IR data presents a possible mechanism of ZnO NP stabilization in the presence of different NOM. This data may be helpful to predict the aggregation behavior of ZnO NPs in environmental and ecotoxicological contexts.
A Power Coupling System for Electric Tracked Vehicles during High-Speed Steering with Optimization-Based Torque Distribution Control

Published: June 2018

It is significant to improve the steering maneuverability of dual-motor drive tracked vehicles (2MDTVs), which have wide applications in the tracked vehicle industry. In this paper, we focus on the problem of insufficient propulsion motor power during high-speed steering. Some correction formulas are introduced to improve the accuracy of the mathematical model. A steering coupling system and an optimization-based torque distribution control strategy is adopted to improve the lateral stability of the vehicle. The 2MDTV model and the proposed control strategy are built in the multi-body software RecurDyn and the control software Matlab/Simulink, respectively. According to the real-time steering simulation by the hardware-in-the-loop (HIL) method, the 2MDTV with the coupling device outputs more power during high-speed steering. The results show the speed during steering is quite high though, the stability of the vehicle can be achieved due to using the torque distribution strategy, and the steering maneuverability of the vehicle is also improved.
Catalytic Oxidation of Synthesis Gas on Platinum at Low Temperatures for Power Generation Applications

Published: June 2018

This paper addresses the issues related to the low-temperature catalytic oxidation of synthesis gas at high pressures under lean-burn conditions. The purpose of this study is to explore the mechanism responsible for the interplay between carbon monoxide and hydrogen during their combined oxidation process. Particular attention is given to the temperature range from 500 to 770 K, which is relevant to the catalyst inlet temperature encountered in catalytic combustion gas turbine systems. Computational fluid dynamics simulations were performed by using a numerical model with detailed chemistry and transport. Reaction path analysis was conducted, and the rate-determining step in the reaction mechanism was finally identified. It was shown that there is a strong interplay between carbon monoxide and hydrogen during the combined oxidation process. The addition of hydrogen causes a great change in the adsorbed species on the surface of the catalyst. At temperatures as low as 600 K, the presence of hydrogen makes the active surface sites more available for adsorption, thus promoting the catalytic oxidation of carbon monoxide. The coupling steps between the two components make a small contribution to the promoting effect. At temperatures below 520 K, the presence of hydrogen inhibits the catalytic oxidation of carbon monoxide due to the competitive effect of hydrogen on oxygen adsorption.

The assessment of the long-term impacts of drought on tree growth decline using tree-ring analyses may be used to test if plantations are more vulnerable to warming after successive droughts, leading to a “cumulative stress” effect. We selected 76 Pinus pinaster trees (declining and non-declining trees), and basal area increments over the last 20 years (BAI20) were calculated to build the chronologies for the stand types and vigor classes. Resistance, recovery and resilience indices were calculated. Pearson correlations, analyses and Partial Least-Squares regression were used to analyze the relationships among the response and environmental variables. We found a negative and significant relationship between mean temperature for May and June of the current year and growth in the naturally regenerated stands. This negative effect on growth under warm spring conditions was more noticeable in plantations than in naturally regenerated stands. A negative trend along time was found for the resilience index in planted stands. Evapotranspiration, maximum temperature and annual radiation showed significant and negative correlations with the growth of declining trees from planted stands, indicating they are susceptible to drought stress. Declining trees in planted stands showed a loss of growth resilience, specifically a negative trend after successive droughts.
StegNet: Mega Image Steganography Capacity with Deep Convolutional Network
Authors: Wu Pin , Yang Yang , Li Xiaoqiang
Published: June 2018

Traditional image steganography often leans interests towards safely embedding hidden information into cover images with payload capacity almost neglected. This paper combines recent deep convolutional neural network methods with image-into-image steganography. It successfully hides the same size images with a decoding rate of 98.2% or bpp (bits per pixel) of 23.57 by changing only 0.76% of the cover image on average. Our method directly learns end-to-end mappings between the cover image and the embedded image and between the hidden image and the decoded image. We further show that our embedded image, while with mega payload capacity, is still robust to statistical analysis.
