Typhoon Saomai(0608) is the strongest typhoons landed in China mainland nearly 50 years,which is characterized by very low central pressure,very great wind speed,particularly concentrative precipitation and energy,rapid development,fast movement and so on.It has a particularly strong destructive power in the energy concentration area,which is irresistible and cause direct economic losses over 111 billion Yuan in Zhejiang and Fujian provinces because its intensity is extremely strong.Thus,it is very significant to analyse observational features and causes of explosive development of super typhoon Saomai(2006) over coastal water of China.This paper takes full advantage of meteorological observations from modern means.FY-2C infrared images show that,in the process of typhoon Saomai strengthening,the typhoon outer clouds was absorbed by the typhoon outer core region with the significantly reduced storm diameter,more dense structure,and the clear typhoon eye developed from the fuzzy one.In the rapid strengthening phase,the typhoon rapidly shrink inward with a concentric eyewall structure and development characters of deep-wall convective cloud spiral rain band.Based on the echo data(composite reflectivity and radial velocity) observed by the new generation weather radar CINRAD/SA in Wenzhou,we can find the fact that the typhoon is still strengthened until 1-hr before landing.From the composite reflectivity data,we can see that the typhoon eye developed from a single eyewall into a double one,subsequently developed into one with more profound eyewall,which is corresponding to a development process,i.e.from a high speed area to two high speed areas,until to a higher speed area shown in the radar radial velocity map.Based on the 3-hr pressure variation of auto weather stations,we can judge the strong wind velocity by calculating the surface pressure gradient before and after landing.By combining the pressure gradient and hourly direction change of maximum wind,we can decide the landing point and do a short-term forecasting on the moving path after landing.The hourly accumulated rainfall distribution shows that it has an apparent asymmetry feature,and the rainfall on the right side of typhoon advancing direction is larger than that on the left one,going with the heavy precipitation mostly concentrated in the main region of typhoon circulation and without the obvious external precipitation.

In response to a request from the Communication Workers of America, an evaluation was made of possible leakage of radiofrequency/microwave (RF/MW) radiation from long-distance telephone relay equipment at Mountain Bell, in Idaho Falls, Idaho. Measurements were taken of RF/MW radiation around transmitters, associated waveguide runs, transmitting and receiving dishes, and at the relay station. Measurements were also made at the central transmitting station in Idaho Falls where nine transmitter/receivers and one paging system were evaluated. All produced less than the detection limits of 10 microwatts per square centimeter for power density and 500 volts squared per square meter for electric-field measurements. As part of the medical evaluation, eight current employees and one former employee were interviewed. None reported any medical conditions which the authors believed were work-related. All current workers denied specific symptoms. The retired worker did report neurologic symptoms, however, medical evaluation of his symptoms did not identify a cause for his condition. The authors conclude that there is currently no danger from microwave radiation at these sites, and since there has been almost no modernization of the equipment in some years, there is little chance that such exposures have occurred.


Editorial cartoons have an unchallenged history as a unique and important artefact in both political and cultural discourses. In journalism, they offer varied insights and may eventually alter beliefs and opinions, influence politics, trigger discussions, and give life to ideas. This paper investigates the signs and meanings of editorial cartoons published in a campus newspaper of a tertiary school in the Philippines. It anchors on Chandler's semiotic concepts in analyzing the editorial cartoons that incorporate both the Saussurean dyadic concept of signs, signifier and signified, and the Peircean triadic concept of signs as symbolic indexical, and iconic. It also considers Leymore's idea of the figure and ground, which identifies the primary, secondary, and tertiary signifiers based on their importance or impact on editorial cartoons. Analysis shows that editorial cartoons contain all types of signifiers, primary, secondary, and tertiary, which work together to effectively convey the intended meanings to its target readers. These signifiers also possess certain characteristics as being symbolic, indexical, and iconic and they blend together to enrich the editorial cartoons' intended meanings. Furthermore, these editorial cartoons illustrate the newspaper's perceptions as well as its stand on various issues and concerns relating or affecting the students and the whole academic community. Although these editorial cartoons are only published in the campus newspaper, they do not only deal with important local issues and concerns but in the national and global spheres as well.


We explore the relationship between stock splits and subsequent long-term returns during the period from 1950 to 2000. We find that, contrary to much previous research, firms do not exhibit positive long-term post-split returns. Instead, we find that significant positive returns after the announcement date do not persist after the actual date of the stock split. We also observe that abnormal returns are correlated with the price-delay or market friction. We conclude that the stock-split post-announcement "drift" is only of short duration, and it is attributable to trading frictions rather than behavioral biases.

As a candidate of dark matter, primordial black holes (PBHs) have attracted more and more attentions as they could be possible progenitors of the heavy binary black holes (BBHs) observed by LIGO/Virgo. Accurately estimating the merger rate of PBH binaries will be crucial to reconstruct the mass distribution of PBHs. It was pointed out the merger history of PBHs may shift the merger rate distribution depending on the mass function of PBHs. In this paper, we use 10 BBH events from LIGO/Virgo O1 and O2 observing runs to constrain the merger rate distribution of PBHs by accounting the effect of merger history. It is found that the second merger process makes subdominant contribution to the total merger rate, and hence the merger history effect can be safely neglected.


The prehistoric site of Franchthi Cave located in the south-eastern Argolid in Greece yielded an exceptionally rich collection of personal ornaments. A reassessment of this category of material culture by two of us (CP and MV) led to the hypothesis that one type of personal ornaments, i.e. marine shell beads belonging to the species Cyclope neritea, were intentionally heated to change their natural whitish colour to black. In order to identify possible diagnostic criteria for intentional heating based on the physical properties of the shells we submitted two modern Cyclope neritea shells, one of which unmodified, the other experimentally blackened through heating, and two archaeological specimens, one presenting a natural whitish colour, the other black, to complementary analytical methods: optical (OM) and scanning electron microscopy coupled with an X-ray analysing system (SEM-EDX), infrared (FT-IR) and microRaman spectroscopy as well as differential scanning calorimetry (DSC). Results show that heated shells can be identified based on their microstructure and chemical composition and that the black archaeological shell positively matches the modern shell blackened through heating. Identification of the limited conditions, in which blackening through heating occurs, further supports a special heat-treatment for Cyclope neritea shells at Franchthi Cave.


Detection of chlorpyrifos (CPF) using a surface plasmon resonance (SPR)-enhanced photoelectrochemical sensing system is demonstrated in this study. The presence of CPF was detected based on an increase in the short-circuit photocurrent when a sample is injected into the electrolyte at different concentrations. The short-circuit photocurrent signal was enhanced by both localized SPR of the gold nanoparticles and by the effects of grating-coupled propagating SPR. Using the hybrid SPR-enhancement system, CPF detection was achieved at concentrations as low as 7.5 nM. The proposed technique of leveraging a multifunctional photovoltaic effect can be used for a variety of sensing applications.


This research aims to analyze the influence of a hedonic lifestyle on consumptive behavior in purchasing clothes via e-commerce among students. The author uses a quantitative research approach as a procedural step in this research. The author uses the Estok Navitte Cowan formula to determine the sample used. For the sampling process, the author used a non-probability sampling technique. The next technique used was quota sampling, with a total of 30 students. The author uses surveys as a way to collect data and chooses questionnaires as a tool to collect the necessary data from research subjects. The Likert scale was used in this research. Researchers use Google Forms as a tool for collecting data for research. The author uses the data analysis method of recall and data categorization. Based on the research results, it shows that the hedonic lifestyle adopted by respondents is partially in the high category. Both aspects of activities, interests, and opinions related to the research object can help construct a hedonistic lifestyle. In this research, aspects were found that could construct a dominant hedonic lifestyle, such as shopping, being interested in fashion, and thinking about products. Consumer behavior in purchasing clothes in e-commerce carried out by respondents is in the high category. The types of consumer behavior in the high category are impulsive purchases and irrational purchases. These two types of consumer behavior can occur because respondents look for symbols of satisfaction and pleasure attached to clothing in e-commerce. However, the level of waste in purchasing clothes through e-commerce is low.


As the need for a video coding technology for a machine that performs intelligent analysis such as object detection, segmentation, and tracking on massive video data has emerged, MPEG is developing a standard called video coding for machines (VCM). VCM is a standard technology for compression of image/video or its features for performing vision tasks of intelligent machines. In this paper, we propose methods that convert multichannel features extracted from an analysis network of input images into a reordered feature map sequence for enhanced compression using VVC. The proposed methods exploit the correlation between channel feature maps using their mean values and sum of absolute difference (SAD) between feature maps in the reordering. Although the proposed methods do not reach the anchor performance of VCM, it shows better coding performance than compressing the feature without channel reordering.


In order to observe soil water dynamics and water consumption in different multiple cropping systems by regarding it as a whole,analysis was made of soil water dynamics,water satisfied rate,daily water consumption and yield of different treatments.The results showed that: planting two crops in a year under the condition of 640 mm annual mean rainfall in the Loess Plateau conduced to the substantial use of solar and water resources in summer fallow,the biomass yield,economical yield and water use efficiency was improved in different degrees,and the material cycle was enhanced.The daily water consumption of treatment Ⅲ and treatment Ⅳ were only higher by 0.07 mm/d and 0.1 mm/d compared with the contrast,treatment Ⅱ was equal to the contrast.The best economic returns of multiple cropping systems were "wheat—maize".The best sustainability of soil water is "wheat—foxtail millet".In the premise of significant economic benefits,multiple cropping systems can be sustainablly developed.The optimum multiple-cropping systems with efficient resources utilization and high economic benefits are "wheat—maize" and "wheat—soybean".

We have studied charge-density-wave (CDW) transport in NbSe 3 at temperatures below 45 K. Between the threshold electric field ET and a second characteristic field ET, the CDW conductivity varies as σ CDW ∞exp(-Δ/k B T), with an activation energy 4 comparable to the CDW gap. Above ET, the CDW conductivity increases, in many crystals via an abrupt «switch,» to a much larger, only weakly temperature-dependent value. Contrary to previous suggestions, we find that ET is determined by bulk CDW pinning and dynamics, not by isolated defects

Purpose
The purpose of this study is to examine determinants of profitability of non-financial firms listed small- and medium-sized enterprises (SMEs) in the UK from 2012 till 2020. It has been argued that profitability plays a key role in economic development and growth. Despite the important role that SMEs play in developed economies like UK, academic research into SMEs profitability determinants in developed countries is not extensive.

Design/methodology/approach
The methodologies used include dynamic panel data estimation techniques. Relationship of nine independent variables with profitability was examined. Two models are created using return on assets (ROA) and return on equity (ROE) as dependent variables. Size, age, efficiency, working capital, liquidity, leverage and volatility of the firm represent firm-specific independent variables. Two macroeconomic variables, namely, gross domestic product and inflation are also used as independent variables. Data obtained from Thomson Reuters Data Stream for 93 listed SMEs companies in the UK from 2012 to 2020. Fixed effects, random effects and generalized method of moments were used in data analysis.

Findings
All variables showed significant influence on profitability, except liquidity reflecting insignificant impact on profitability in two regression models conducted for 93 firms under study. Efficiency, liquidity and leverage are the only three independent variables with similar impact on both ROA and ROE.

Practical implications
Identifying determinants of profitability will help stakeholders and corporate executive make sound decisions to ensure sustainability and stability at the firm level. This is particularly important given the key role played by SMEs in economic development and growth. The findings of this study would help direct financial management practices to ensure a favorable sustainable organizational performance.

Originality/value
This study differs from previous studies that focused mainly on developing countries; with limited research conducted on profitability of SMEs in developed economies. To the best of the author's knowledge, this is the first study to examine factors influencing profitability of SMEs in UK. Previous studies concentrated on service sector like insurance and hotel firms.


This study conjectures and shows that the level of top management stock ownership is non-monotonically associated with managers' propensity to manage earnings. Increasing ownership from low levels decreases earnings management while ownership at high levels increases earnings management. Further, this study attempts to discern when the effects of management ownership are more salient for the firm. The results of this exploratory analysis of 15,945 firm observations over a six-year period show that the non-monotonic association between top management ownership and earnings management is significant, and hence more important, for the firm characteristics of low growth opportunities, high operating volatility, small size, frequent losses, high-technology, and low institutional ownership.

How do international organizations in the United Nations system put together their budgets? What is the role of complex principals—most notably member states—and the complex agents in the bureaucracies of international organizations in budgeting processes? And what does a focus on budgeting tell us about the changing nature of the system of international organizations? This book provides answers to these questions through a detailed examination of budgeting in the UN system. The analysis draws on both quantitative and qualitative observations for a total of twenty-two UN system organizations and detailed case studies for the United Nations, ILO, UNESCO, and WHO. The findings demonstrate the importance of three key organizational outcomes—proceduralization, routinization, and budgetary segmentation—as international organizations grapple with managing discord over priorities as a result of complex principal–agent constellations. Contrary to a common view of international bureaucracies as pathological organizations, core budget routines are mostly successfully maintained. However, principal constellations are becoming more complex, notably through the rise of voluntary contributions and non-state donors; budgetary segmentation advances (in some cases even leading to the setting up of new international organizations); and budgeting and resource mobilization have become ever more intertwined. As a consequence, the capacity of international bureaucracies to fulfill their budgeting responsibilities is stretched to the limit and beyond.


This work aims to improve the classical white‐box model of an inverted pendulum in order to reach a more accurate representation of an actual pendulum on a cart system. The purpose of the model is to train different controllers based on machine learning algorithms. In the context of this paper, the inverted pendulum system is driven by a belt drive that is controlled by a stepper motor. Due to the nature of the controller, the input to the stepper motor is in the form of a non‐smooth bang‐bang‐like signal that moves the cart to the left, right, or terminates its movement. One of the main challenges, in this case, is to find a proper function to model the stepper motor as its dynamics cannot be captured with a constant gain. It has been shown that the transient behavior of the stepper motor when changing direction or stopping is not negligible in the closed‐loop control performance. Accordingly, a grey‐box scheme, which accounts for the uncertainties that are not included in the vanilla white‐box model, is utilized to achieve a lower model mismatch compared to the actual pendulum. Initially, the equation of motion was derived using the Euler‐Lagrange equation with force on the cart as the control input. But in the real‐time experiment, the interface is realized by the stepper motor's frequency modulator, hence a transfer function representing the relationship between the frequency and the force applied on the cart (in the model) is calculated as a black‐box model. To improve the accuracy of the transfer function, an experimental data‐driven design of this function is performed based on modern schemes in system identification. For this purpose, the applied frequency to the stepper motor and the states from the actual system are recorded. Then, the applied force on the cart is calculated using the equation of motion and the recorded states. It is also shown that the frequency‐force transfer function uncertainty due to exogenous disturbances is non‐negligible and with the aim of having a more accurate model, an artificial neural network is introduced. Finally, the effectiveness of this grey‐box model is shown by training and implementing a deep Q‐network based controller to swing up and balance the inverted pendulum.


This work involves the application of adaptive hierarchical grids to free surface Navier-Stokes simulation of viscous waves in a stationary tank and their interaction with a cylinder. Adapting quadtree grids are combined with a volume of fluid (VoF) approach, in which a high resolution interface capturing scheme is used for advection of the interface. The Navier-Stokes equations are discretised using finite volumes with collocated primitive variables and solved using the PISO (Pressure Implicit with Splitting of Operators) algorithm. The cylinder is included by using the technique of Cartesian cut cells. Grids adapt to follow the movement of the free surface and to provide refinement in areas of high vorticity. The method is used to simulate small amplitude viscous waves in a unit square tank, separated flow past a cylinder and preliminary results are presented for the fluid structure interaction occurring when a cylinder moves into a tank of still water and for viscous waves in a tank containing a submerged or surface piercing cylinder. Results agree reasonably well with available analytical, experimental and numerical data.

Th e eff ects of N fertilization rates on the abundance and community composition of NH 3 –oxidizing bacteria (AOB) are poorly understood, particularly in greenhouse-based high-N-input vegetable soils. Th e abundance and community composition of AOB from these vegetable soils under fi ve N (urea) rates in eastern China were evaluated by polymerase chain reaction (PCR) and denaturing gradient gel electrophoresis (DGGE). Th ese rates were: the conventional high N rate (N4) as 270 or 300 kg N ha −1 season −1 for cucumber (Cucumis sativus L.) or tomato (Solanum lycopersicum L.), respectively, and 80% (N3), 60% (N2), 40% (N1), and 0% (N0) of the N4 rate. Aft er 2 yr of a cucumber–tomato rotation, N fertilization had signifi cant eff ects on the abundance and community composition of AOB. Th e abundance of AOB amoA gene was signifi cantly higher under the N2 (2.08 × 10 10 kg −1 dry weight soil) than under the N0 or N4 (8.74 or 8.75 × 109 kg −1 soil). Th e DGGE patterns were more diverse under N1 and N2 than under N3 and N4, with the greatest DGGE band numbers (15) under N2. Phylogenetic analyses of amoA gene fragments showed that AOB sequences from diff erent N fertilization rates were affi liated with Nitrosospira species and grouped into Clusters 2, 3, 8, and 12. Our results indicate that a reduction to 40% of the conventional high N rate (N4) is practical to reduce N inputs while maintaining the abundance and community composition of AOB in such greenhouse-based vegetable soils.


Title of Dissertation: FEIGNED HISTORIES: PHILIP SIDNEY AN D THE POETICS OF SPANISH CHIVALRIC ROMANCE Timothy D. Crowley, Doctor of Philosophy, 2009 Dissertation directed by: Professor Donna B. Hamilton Department of English This study re-evaluates Sidney's method and purpose for inventing Arcadia, through analyzing his fiction in tandem with the Spanish genre of chivalric "fei gned history." It introduces the new perspective that Arcadia exploits structural and thematic focus on clandestine marriage in Feliciano de Silva's feigned Chronicle of Florisel de Niquea, Part Three (1535), as rendered in translation by Jacques Gohory as "Book" Eleven in the French Amadis cycle (1554). Old Arcadia follows that chivalric paradigm in Books One through Three; then it employs motifs from ancient prose fiction by Apuleius and Heliodorus in Books Four and Five to amplify plot conflict tied to the protagonist lovers' secret marriages. Imitation of Spanish pastoral romanc es by Montemayor and Gil Polo in Old Arcadia's Eclogues supplements the work's primary narrative plane and also facilitates Protestant aesthetic impressions of marriage and affective individual piety. Shifts in literary source material occur as me ans to extend and enrich thematic focus and narrative poetics of those first three Books. Sidne y's narrative establishes admiratio for its protagonist lovers and reader complicity with them, while imposing comic and tragic distance from other main characters. These observations revise dominant critical assumptions about Old Arcadia. Building upon its chivalric source material, Sidney's fiction increases veri imilitude and invents its own rhetorical focus on dynastic union through clandestine marriage. Thi s study observes for the first time that political tension and legal debate in Old Arcadia's conclusion revolve around that issue. Sidney's fiction figures forth a succession c ri s contingent upon legal complications with the issue of clandestine marriage in Arc adia, in a manner congruous with Genevan, French, and Tridentine legal reform on that matte r, as well as with England's unique legal situation regarding secret marriage. The story's intellectual focus on justice and equity complements its author's concern with t he case of his uncle Robert Dudley, Earl of Leicester. While Sidney composed Arcadia, his own political and economic prospects remained largely contingent upon Leicester' s sec et marriage. This study opens new avenues for research on continuity in Sidney's oeuvre and on New Arcadia's influence in English prose fiction and drama of the 1590s and the seventeenth century.

Due to the importance of blood vessel detection in many medical tools and the increasing demand for portable diagnosis equipment, fast blood vessel detection algorithm in a standalone and portable device is very important. The optimization of a computationally intensive algorithm such as this on a mobile platform is challenging due to the limited resources available. In this paper, the blood vessel detection system is implemented and optimized in a portable device running Android OS on an ARM-based processor. The performance of Java programming model and native programming model are compared with respect to the execution time for blood vessel detection. The experimental results show that the blood vessel detection system has worked well in the ARM platform with the Android OS. Moreover, native programming platform is faster than Java programming with 75.91% better in terms of execution time on average. With multithreading, the performance gain in native programming is 92.77% faster than Java programming.


The present study described a rapid and cost-effective method for the enrichment of botrallin and TMC-264 as major bioactive dibenzo-α-pyrones in the endophytic fungus Hyalodendriella sp. Ponipodef12 by macroporous resins. Resin SP825 L displayed the best adsorption and desorption properties for botrallin and TMC-264 among 6 resins. The optimal conditions for resin SP825 L adsorption of botrallin and TMC-264 were processing bed volumes(BV) as 28 BV,flow rate as 3 BV/h,p H value as 5. 0,and temperature as 25 ℃. Those for desorption were ethanol-water elution system at the ratio of 50 ∶ 50(v/v),eluent volume as 7 BV,and flow rate as 4 BV/h. After one round treatment with resin SP825 L,the contents of botrallin and TMC-264 were increased from 2. 18% and 0. 65% in the crude extract to 20. 66%and 6. 58% in the final product,respectively. About 150 mg of the final product was obtained from 1600 mg of crude ethyl acetate extract. The recoveries for botrallin and TMC-264 were 88. 85% and 94. 90%,respectively. The results demonstrated that resin SP825 L chromatography can be an appropriate strategy for obtaining botrallin and TMC-264 from the crude extract. The optimized process will be beneficial for large-scale preparation of botrallin and TMC-264 from Hyalodendriella sp. Ponipodef12.


Recently, a pneumatic flow mixing method has been developed for sea reclamation and land development, in which soft soil is mixed with a relatively small amount of stabilising agent in a transporting pipe. The soil mixture forms several separated mud plugs in the pipe, and is thoroughly mixed with the help of turbulent flow during transportation. This method was adopted to construct part of a man-made island for the Central Japan International Airport at the Ise Bay area in Nagoya. In the construction project, a total of 8.6 million m3 of dredged soil was stabilised by the method for sea reclamation. During the construction, quality control and assurance of manufacturing the treated soil were carried out with an automated control system and laboratory tests on sampled soils. In this paper, the quality control system developed in this project and the quality assurance of the improved ground are described in detail.

Recognition of the 5′ splice site by group II introns involves pairing between an exon binding sequence (EBS) 1 within the ID3 stem–loop of domain 1 and a complementary sequence at the 3′ end of exon 1 (IBS1). Solution NMR is used to show that the EBS1 region is flexible in the absence of pairing with binding of IBS1, but pairing with IBS1 forms a structured 7-bp duplex that terminates at the 5′ splice site in spite of the potential for additional A-U and G•U pairs. This finding, combined with data extracted from published structures, suggests that definition of the splice site is governed by constraints of the helical geometry within the ID3 loop. This feature and flexibility of the uncomplexed ID3 loop appear to be common to both the ai5γ and O.i. introns and may help to fine-tune elements of recognition in group II introns.


A 49-year-old woman was evaluated for an 8-day history of painless jaundice. Blood tests revealed an elevation of serum bilirubin (5.2 mg/dL) and a mild elevation of alanine transaminase and aspartate transaminase. Serum levels of alpha fetoprotein (AFP, 178.3 ng/mL; normal < 8.0 ng/mL) and carbohydrate antigen 19-(CA19-9, 40.7 U/mL; normal < 22 U/mL) were increased. Ultrasonography showed dilatation of the intrahepatic and extrahepatic bile ducts. Contrast-enhanced computed tomography (CT) revealed a thickened biliary wall with enhancement in the distal common bile duct (Fig. 1a). Biliary tract malignancy was considered, and pancreaticoduodenectomy was performed. After surgery, the serum AFP decreased to 7.1 ng/mL. Histological examination showed the tumor composed of adenocarcinoma (Fig. 2a) that was immunopositive for AFP (Fig. 2b). She was diagnosed with AFPproducing distal cholangiocarcinoma (DCC). One year later, she was readmitted because of an increased AFP level (704.3 ng/mL). Although magnetic resonance imaging (MRI) showed no evidence of loco-regional recurrence, there was a 12cm mass in the right lower quadrant (Fig. 1b). On abdominal CT, the lesion was closely related to the right adnexa and uterus. During laparotomy, no peritoneal seeding was observed, and a mass arising from the right ovary was confirmed. The intraoperative frozen section manifested adenocarcinoma. She underwent bilateral salpingo-ophorectomy and hysterectomy. Histopathologically, the adenocarcinoma cells that looked similar to cholangiocarcinoma cells (Fig. 2a) in morphology were immunopositive for AFP (Fig. 2b & 2c) and CA19-9 (Fig. 2d), but immunonegative for CA125, PAX8, and SALL4. Finally, the diagnosis was ovarian metastasis from DCC. She refused adjuvant chemotherapy and was followed-up for 9 months without recurrence. Elevation of serum AFP is common in hepatocellular carcinoma and non-seminomatous germ cell tumors but rare in DCC. In the presented case, the rise of serum AFP is attributed to the production by the DCC because the tumor was positive for AFP staining and serum AFP decreased to the normal level after tumor resection. The mechanism of AFP production in cancer cells remains unclear, and cancer stem cells may play an important role in it. Ovarian metastasis is developed mainly from the malignancies of the gastrointestinal tract and breast. DCC metastatic to the ovary is extremely rare. Although secondary ovarian tumor may resemble primary ovarian cancer, clinical history and immunohistochemistry are useful for the differential diagnosis. In our case, DCC was identified 1 year earlier than ovarian tumor that was immunopositive for CA19-9 but immunonegative for CA125, PAX8, and SALL4.


Sodium pumps of cardiac plasma membranes were studied in young, spontaneously hypertensive rats (SHR) and in their normotensive controls (Wistar-Kyoto; WKY) using the two following methods. The enzymatic activity and its sensitivity to ouabain were measured as the Na+, K + -dependent ATP hydrolysis, and the number of pumps was estimated by [3H]ouabain binding. The main results of this study were the observations that (a) concentrations of ouabain as low as 10-10M inhibited 10–15% of the enzyme activity in both strains; (b) Na +, K + -adenosine triphosphatase (ATPase) activity in membranes from SHR was double that in membranes from WKY (16.5 ± 3.2 μmol Pi/h/mg protein vs. 8.2 ± 1.2 μmol Pi/h/mg protein for 10-7 M ouabain; p < 0.01); (c) sensitivity to three different cardiac glycosides, ouabain, digoxin, and digitoxigenin, was identical in SHR and WKY vesicles; and (d) the binding capacity of [3H]ouabain was significantly higher in SHR than in WKY vesicles, but the dissociation constant (KD)did not appear to differ between the two substrains. These studies, performed on 3-week-old rats before the appearance of hypertension, showed, on the one hand, the existence of a Na +, K + -ATPase of very high affinity in the rat heart, and, on the other, that cardiac sarcolemmal membranes from SHR had a greater number of sodium pumps than those from WKY and thus a greater ability to extrude sodium.


The stable polyacrylamide( PAM) dispersion was synthesized via dispersion polymerization in the ionic liquid using acrylamide( AM) as the monomer,2,2'-azobis( 2-methylpropionitrile)( AIBN) as the initiator. The effects of the monomer concentration,the dosage of initiator,reaction time and reaction temperature on the polymerization process were investigated. The results showed that the optimum conditions of synthesis of PAM were as follows: The reaction time was 10. 0 h,the initiation temperature 70 ℃,the concentration of monomer 1. 6 mol / L,and the dosage of initiator 2%( monomer). The molecular weights of PAM obtained by dispersion polymerization were as high as 1. 05 × 107 g / mol with good water solubility. The structure of polymer was confirmed by FTIR.


English voice,the active or passive,as special inflectional forms,is an important means for us to cognize and depict the world around us.The choice between them is by no means optional,but is closely related or determined by various factors such as meaning,text,situation,etc.We ought to take a micro-cosmic point of view in the pragmatic use of them when we portray the world or write an article.


New modified detector design and arrangement for 4 Mbit permalloy devices operating at 200 kHz and 60 Oe triangular driving field have been developed. The new detector gives the stable output signal waveforms for the variation range of the driving field of 45 Oe to 70 Oe and about three times larger output signal levels compared with that of a 1 Mbit device detector. A minimum required driving field, HRmin, limited by a ω-2ω transition noise at the detector is reduced by optimizing the direction of the detector lines with respect to a bubble holding in-plane field, HDC which is necessary for start/stop operation. By introducing this modified detector pattern and arrangement, we have realized the operation of the 4 Mbit permalloy devices with good characteristics at 200 kHz and 60 Oe triangular driving field in the temperature range of -5°C to 70°C.


Radiation therapy has been getting progressively more complex for the past 20 years. Early radiation therapy techniques needed only basic dosimetry equipment; motorized water phantoms, ionization chambers, and basic radiographic film techniques. As intensity modulated radiation therapy and image guided therapy came into widespread practice, medical physicists were challenged with developing effective and efficient dose measurement techniques. The complex 3-dimensional (3D) nature of the dose distributions that were being delivered demanded the development of more quantitative and more thorough methods for dose measurement. The quality assurance vendors developed a wide array of multidetector arrays that have been enormously useful for measuring and characterizing dose distributions, and these have been made especially useful with the advent of 3D dose calculation systems based on the array measurements, as well as measurements made using film and portal imagers. Other vendors have been providing 3D calculations based on data from the linear accelerator or the record and verify system, providing thorough evaluation of the dose but lacking quality assurance (QA) of the dose delivery process, including machine calibration. The current state of 3D dosimetry is one of a state of flux. The vendors and professional associations are trying to determine the optimal balance between thorough QA, labor efficiency, and quantitation. This balance will take some time to reach, but a necessary component will be the 3D measurement and independent calculation of delivered radiation therapy dose distributions.

ABSTRACT Enlightenment thinkers wrote many pages against the Inquisition. In particular, they widely criticized the Spanish and Portuguese inquisitions, which they regarded as the epitomes of cruelty and fanaticism. Both inquisitions were established at royal request and remained subjected to the authority of the kings until they were abolished at the beginning of the nineteenth century. Indeed, therein the kings nominated the grand inquisitors, who were invested with civil jurisdiction for reasons that were at least as much political as religious. However, Enlightenment writers almost always portrayed the Inquisition as the ultimate example of the many ills derived from clerical authority, ecclesiastical autonomy and monastic despotism. Kings and civil magistrates were, in fact, usually depicted as victims of inquisitorial power. This common portrayal of the Inquisition reveals that the Enlightenment idea of toleration was essentially constructed for reducing the power of churches to disturb public peace and challenge civil authority. Thus, this idea of toleration was in effect less capable of denouncing political intolerance, let alone of promoting the separation of church and state.


The purpose of this paper is to measure the effects of each dimension of entrepreneurship on the risks of Tunisian family businesses. The data for this study were collected through a survey, conducted face to face, with 110 Tunisian family businesses chosen from the database constructed by the Agency for the Promotion of Tunisian Industry. The use of survey results leads us to emphasize, based on linear regressions and correlations, the existence of a statistically negative significant relationship between the dimensions of entrepreneurship and the types of risks of the Tunisian family businesses. The originality of this research appears in the fact that we were able to tackle a subject that has not been adequately studied before, either theoretically or empirically, by researchers, in one hand, and, it is a novel study in the Tunisian family businesses which aim to reduce costs and risks, and maximize value in order to assure their survival, on the other hand.

Questions about tuberculosis that are often asked of infectious disease specialists are addressed in a very practical manner.


The issues of using Euclidean and Hamming distances between fuzzy sets in the process of analyzing threats to information security of industrial automation systems are considered. This approach allows one to formally describe the degree of danger of various categories of information security threats (and their combinations), taking into account the mathematical interpretation and graphical visualization of the danger level of these threats. This, in turn, makes it possible to increase the visibility and reliability of vulnerability monitoring data in order to make decisions on the degree of their danger, and allows one to select or develop adequate measures for the effective protection of industrial automation systems. The features of applying the results of mathematical calculations of various Euclid and Hamming distances for fuzzy sets, which are typical for plotting graphs, which make it possible to reduce the fuzziness of the description of the level of threats of a different nature, are discussed. The results of an experimental calculation are described, which make it possible, as an example, to judge the degree of danger of certain categories of threats and their combinations for industrial systems of this class.


The development and management of the Czech landscape has been influenced by several key factors in the past. One important factor is the development of society, particularly political changes and ecological development. Others include the level of knowledge and understanding of technologies, scientific knowledge and the non-productive importance of the landscape, as well as the attitude of society and individuals towards the landscape. In the past, non-forest woody vegetation was a standard part of the European agricultural landscape and formed its typical appearance. The onset of collective farming during the second half of the twentieth century resulted in transforming the landscape into open fields without permanent vegetation. The landscape became everyone's and no-one's and was subject to orders, tasks and plans. The key goal of this article is to evaluate non-forest woody vegetation from a landscape-ecological aspect and compare the occurrence of non-forest woody vegetation in four landscape types. The submitted study presents various types of non-forest woody vegetation, the species present in elements of scattered greenery and the spatial arrangement depending on the method of management and use of the territory.


There are literally hundreds of syndromes associated with short stature which have different prognoses, complications and responses to treatment (1 -3). A specific diagnosis is essential for accurate prognosis, treatment and genetic counselling. The first step in the clinical evaluation of short stature is to determine whether the body habitus is proportionate or disproportionate (Fig. 1). In general, children with disproportionate short stature have a skeletal dysplasia, whereas those with proportionate short stature usually have a more generalized disorder, such as intrauterine growth retardation (IUGR), malnutrition, chronic disease, psychosocial dwarfism, chromosomal anomalies or an endocrine disorder. Exceptions to this rule d o occur, however, such as the disproportionate dwarfism in severe cretinism or the proportionate shortening in osteogenesis imperfecta. A mildly disproportionate body habitus may not be apparent on casual examination, and thus anthropometric measurements, such as sitting height or upper/lower segment ratio and arm span, must be made before a relatively mild skeletal dysplasia, such as hypochondroplasia, can be excluded. Once a person with short stature is found to be proportionate, it is helpful to determine whether growth deficiency was of prenatal or postnatal onset. Prenatal onset growth deficiency usually implicates a fetal environmental insult or general cellular genetic defect. Late fetal insults are more likely to result in catch-up growth postnatally than prolonged


In order to inspect the reliability level of the approximate wave function in molecular physics,we calculated the approximate wave function and the potential energy of the ground state of H2+.We studied the effect of approximate wave function of ground state of H2+ on its potential energy.We got accurate equilibrium position by comparing with RKR potential when z=1.23,but on higher vibrational levels z=1.16 is very well.


Funding information German Research Foundation, Grant/ Award Numbers: DO 453/9-1, AL 474/28-1 Abstract Within this work, the investigation on interactions of a phosphorus-containing flame retardant (FR) DEPAl in epoxy face sheets and five different FRs in the PET-foam core of a sandwich laminate on the fire behavior is focused. Fourteen different combinations of resin face sheets and PET foam cores are produced by vacuum assisted resin infusion (VARI). The combustion behavior of the sandwich laminates is tested by cone calorimetry. The time to ignition is lowered when a FR resin is used while the subsequent burning behavior is mainly influenced by the PET foam core. In order to evaluate the interactions of the flame retardants in the core and face sheet, a total improvement value (TIV) was set up which compares the performance related to the specific FR combinations. The highest TIV value (76%) indicating positive interactions with DEPAl was observed with a 2-PSMP-PET core, the lowest value (−2%) with a DEPZn-PET core.


The advantages and disadvantages of the current constant-flow control method for the constant-flow pump (CFP) are analyzed. By using the experimental data and the BP neural network (BPNN), the model between outlet pressure and flow loss coefficient established. In order to realize constant-flow control for the CFP, a feed-forward controller based on the model is set up finally. Experiments show that this controller can improve the flow control accuracy for the CFP greatly.

(phone: 968-24142535; fax: 968-24413454; e-mail: touatif@ squ.edu.om). M. Loulou is with the national National School Of Engineering of Sfax, B.P. 3038 Sfax Tunisia. (e-mail: email@example.com). Abstract—A design flow of multi-standard down-conversion CMOS mixers for three modern standards: Global System Mobile, Digital Enhanced Cordless Telephone and Universal Mobile Telecommunication Systems is presented. Three active mixer's structures are studied. The first is based on the Gilbert cell which gives a tolerable noise figure and linearity with a low conversion gain. The second and third structures use the current bleeding and charge injection techniques in order to increase the conversion gain. An improvement of about 2 dB of the conversion gain is achieved without a considerable degradation of the other characteristics. The models used for noise figure, conversion gain and IIP3 used are studied. This study describes the nature of trade-offs inherent in such structures and gives insights that help in identifying which structure is better for given conditions.


Many European countries have improved their water quality monitoring since the implementation of the Water Framework Directive (WFD). However, the monitoring strategy (parameter, density and frequency) highly differs among European regions. Annual fluxes, calculated from observations or estimated by models are often computed without any estimation of uncertainties, therefore it is difficult to assess trends as influenced by the mitigation options implemented. Here, we illustrate this challenge on French water quality monitoring network and national scale models. The Nutting (Dupas et al., 2015) model presented here is a conceptual model which links nutrients diffuse and point sources with annual fluxes modulated by catchment and in-stream retention factors. Both retention factors are calibrated in 231 headwater catchments with several variables such as soil, land use and climate factors and. The method consists in: (i) estimating observational uncertainty in inter-annual nitrogen and phosphorus fluxes (2008-2012) and (ii) investigating their consequences on the Nutting (N&P) model calibration. We show that the monitoring strategy highly differs among French river basin districts with higher sampling frequencies in northern France (∼12 samples per year) in comparison with southern France (∼6 samples per year). We estimated fluxes uncertainties based on Moatar et al. (2013) methods which consider sampling frequency, discharge variability and concentration-discharge relationships. The monitoring strategies adopted in different river basin districts affect fluxes uncertainties and consequently the model calibration. The next step will be to analyze the effects of different sampling strategies in order to improve the current monitoring network.


The LPR and STin2 polymorphisms of the serotonin transporter gene (SLC6A4) were combined into haplotypes that, together with quality of maternal parenting, were used to predict initial levels and linear change in children's (N = 138) noncompliance and aggression from age 18-54 months. Quality of mothers' parenting behavior was observed when children were 18 months old, and nonparental caregivers' reports of noncompliance and aggression were collected annually from 18 to 54 months of age. Quality of early parenting was negatively related to the slope of noncompliance only for children with the LPR-S/STin2-10 haplotype and to 18-month noncompliance only for children with haplotypes that did not include LPR-S. The findings support the notion that SLC6A4 haplotypes index differential susceptibility to variability in parenting quality, with certain haplotypes showing greater reactivity to both supportive and unsupportive environments. These different genetic backgrounds likely reflect an evolutionary response to variation in the parenting environment.


We present an extension to the developmental model discussed in (Dellaert and Beer 1994) to be able to co-evolve nervous systems with the bodies of autonomous agents. To this aim we re-introduce this basic model, and then examine the issues that have to be resolved when extending this model towards neural development. To test the extended model, we have handcoded a genome for a functional agent that is able to display a simple behavior related to chemotaxis. We also show that the model can be used in conjunction with genetic algorithms to yield better performing agents.


High-speed switchgear is an essential part of HVDC mechanical circuit breakers. Taking advantage of faster dielectric recovery of vacuum interrupter, DC current interruption can be achieved by vacuum interrupter driven by high-speed operating mechanism and artificial current zero supplied with high frequency commutation current. The current frequency of commutation branch and the mechanical characteristic of high-speed switchgear are studied to develop a 50kV breaking unit as a building block of HVDC circuit breaker. A safe interruption zone where DC current interruption can be successfully made within a range of current frequency and gap distance is found out. Based on the developed building block, a scheme of ±500kV HVDC mechanical circuit breaker with a series of high-speed switchgears is developed successfully.


This note addresses the problem of robust multiobjective filtering for discrete time-delay systems with mixed stochastic and deterministic uncertainties, in addition to unmodeled nonlinearities. A procedure is developed for the design of linear and exponentially stable filters with a bounded error variance, exponential rate of decay, and robust performance for the error system.


Objective: To evaluate the association between 25-hydroxyvitamin D (25OHD) deficiency and glucose metabolism in non-diabetic essential hypertensive (EH) subjects. Design and method: In 180 EH patients (age 50 ± 12 years, 100 males), free of diabetes and cardiovascular events we evaluated clinical variables, fasting and post-oral glucose load (OGTT) levels of glucose and insulin, C-peptide, plasma lipids, serum calcium, PTH, and 25OHD levels, renal function and presence of the metabolic syndrome (MS). Results: Patients with MS had lower 25OHD levels than patients without MS (P = 0.015). The 25OHD levels were significantly and directly related to fasting glucose (r = 0.172, P = 0.021) and HDL-cholesterol (r = 0.160, P = 0.033) and inversely related to age (r = -0.247, P = 0.001), systolic blood pressure (SBP) (r = -0.147, P = 0.020), area under the curve of plasma glucose (G-AUC) (r = -0.261, P < 0.001) and insulin (I-AUC) (r = -0.153, P = 0.047), glucose at 120 min of OGTT (r = -0.241, P = 0.001), triglycerides (r = -0.182, P = 0.014), and PTH levels (r = -0.307, P < 0.001). Subjects with normal 25OHD levels (> = 30 nmol/l) had lower SBP, fasting glucose, G-AUC, I-AUC, and PTH levels than patients with 25OHD deficiency (<30 nmol/l). G-AUC was significantly and directly related to age (r = 0.252, P = 0.001), body mass index (BMI) (r = 0.252, P = 0.001), waist-circumference (r = 0.383, P < 0.001), SBP (r = 0.236, P = 0.001), alcohol intake (r = 0.222, P = 0.004), HOMA-index (r = 0.001, P < 0.001), C-peptide (r = 0.254, P = 0.001), I-AUC (r = 0.266, P < 0.001), levels of calcium (r = 0.180, P = 0.017), PTH (r = 0.182, P = 0.016), triglycerides (r = 0.207, P = 0.005), and inversely related to 25OHD (r = -0.261, P < 0.001) and HDL (r = -0.197, P = 0.008). Furthermore, G-AUC was higher in men than in women (P = 0.013). After correction for age, gender, presence of MS, serum calcium and PTH levels, I-AUC and alcohol intake, G-AUC was independently associated with age (B = 0.197, P = 0.007), male gender (B = 0.162, P = 0.026), presence of MS (B = 0.337, p < 0.001), calcium (B = 0.225, P = 0.001) and 25OHD (B = -0.158, P = 0.037) levels. Conclusions: In non-diabetic EH patients low 25OHD levels are related to G-AUC independently of insulin levels. This association could be mediated by the effect of calcium homeostasis on insulin-resistance, given that the modulation of extracellular calcium and calcium flux across cell membranes by 25OHD may affect insulin sensitivity.

Religious Origins of Modern Science. By EUGENE M. KLAAREN. Grand Rapids, Eerdmans, 1977. Pp. xii+244. $5'95HERE be all manner of things: Theology and Philosophy, Physick, Physics and Metaphysics, Chemistry and Alchemy, History and Cosmology. Here too all manner of thinkers: among them, Aristotle and Calvin, Bruno and Galileo, Bacon, Boyle and Newton, Paracelsus and van Helmont, Toulmin, Merton, and Collingwood. A veritable cornucopia, whose full list of contents might at first suggest one of those sprawling gothic novels which endeavour to reproduce (or satirise) the teeming intellectual life of three centuries ago. But this is no novel, though it loses nothing in interest and indeed fascination thereby. It is rather an informative and stimulating exploration of the emergence of modern natural science as it can be seen in seventeenth-century England, and especially in the work of Robert Boyle.


Abstract This paper summarizes the results of a comprehensive systematic literature survey on the front-end of a project, commissioned by the Project Management Institute. The dedicated literature on the front-end is sparse: although the front-end has been shown to be critical to the strategic success of the project, this phase of the lifecycle is not well understood. This paper presents the literature on the concept of the front-end, and defines a temporarily ordered structure of generic processes that form the 'front-end' and how these fit together as a coherent whole. These start from the preliminaries to the initiative, then the project purpose (for various stakeholders), the initial analysis and scenario analysis; the analysis of alternatives and choice of project concept; assessment of the project, finishing with setting up project execution. It summarises the recent literature at each of these elements in turn, specifically as they relate to the front-end.


This chapter discusses the results of a survey of secondary school students in Sana'a city regarding Science, Technology, and Society (STS) issues. Firstly, the chapter reviews the literature in order to seek for STS issues that should be infused into the science curriculum in Yemen. Secondly, it reports the results of the survey ranking Science, Technology, and Society issues. A valid and reliable questionnaire containing STS issues is administered to a sample of 418 students from 14 schools in Sana'a city. The results of the study reveal that the most salient issues that must be infused into the science curriculum are human health and disease, water supplies, air pollution, and energy shortages. Comparing the mean scores of males and female students, the results show significant differences in 5 themes. Implications for research and development in science education are discussed.

We show that firms reporting sustained increases in both earnings and revenues have (1) higher quality earnings and (2) larger earnings response coefficients (ERCs) in comparison to firms reporting sustained increases in earnings alone. With respect to earnings quality, firms with revenue-supported increases in earnings have more persistent earnings, exhibit less susceptibility to earnings management, and have higher future operating performance. With respect to response coefficients, firms with revenue-supported increases in earnings have both higher ERCs and lower book value response coefficients, consistent with the implications of the Ohlson (1995, Contemporary Accounting Research 12, 661–687) model.

In the abstract of their article, "HEAVEN in the Making: Between the Rock (the Academe) and a Hard Case (a Head Transplant)," Xiaoping Ren and Sergio Canavero (2017) state that "equipoise" and "knowledge" are necessary parts of a "sound ethical debate in biomedicine." Yet in the essay itself, these authors neglect to even mention equipoise. Ren and Canavero do briefly discuss informed consent, but as I explain in the following, it is difficult to believe that they will be able to obtain informed consent for a head/body swap. Finally, even if they do obtain informed consent, it does not necessarily follow that it is ethical for them to conduct this procedure. The equipoise requirement dictates that physicians cannot begin (or continue) a randomized clinical trial unless there is disagreement among experts in the clinical community concerning the relative efficacy of the different arms of the trial. Put differently, if there is a consensus among experts in the clinical community that one arm of a clinical trial is superior to the other arms, the trial must stop. Given that Ren and Canavero are not proposing a randomized clinical trial, the equipoise requirement does not seem to be relevant. That said, if Ren and Canavero are truly committed to engaging in a "sound ethical debate," they could attempt to determine whether their protocol is consistent with the ethical principle that motivates the equipoise requirement: A physician has an obligation to act in the best interest of her patient. Ren and Canavero apparently believe that a head/ body swap would be in the best interest of patients whose medical conditions have no known cures, like patients who suffer from spinal cord injuries. However, given the lack of scientific evidence supporting the claim that the medical condition of these patients will be improved, they only offer hope. Surely, performing procedures that provide hope to hopeless patients is not necessarily acting in the best interest of these patients. It is not difficult to

57 ABSTRACT The use of certain heparinoid compounds to selectively inhibit the growth of mycoplasmas is described. The invention provides a practical means for facilitating the selective identification of mycoplasmas. The identification of mycoplasmas isolated from man is especially useful as a diag nostic aid in prescribing treatment for diseases caused by these microorganisms. Additionally, the invention provides a means of preventing the growth of mycoplasmas in culture media especially media used for tissue cultures in which mycoplasmas frequently occur as undesirable contaminants.


A major issue in modem coastal aquaculture is the deterioration of culture environment by overcrowding and overfeeding, and also by the contamination of several chemical substances from inland water. To avoid such problems, closed recirculating aquaculture systems have increasingly been used, in which water is filtered and recirculated. Rearing fish for a long time in such systems nevertheless results in the accu mulation of various substances, including ammonia, nitrite, nitrate, phosphate, that may negatively affects the physiological functions such as the respiratory, growth and immune systems1-3). Studies of water quality on effective aquaculture are therefore impor tant, especially as no detailed information has so far been published. This study aimed to investigate the effects of water quality changes in the closed culture in which water was not exchanged on physiological functions in male goldfish.

The coordination planning between land use and transportation system is an important premise of solving urban transportation problems and realizing land use integration. This study investigates the interactive and feedback relationship between land use and transportation system from the perspective of access management. By integrating the land use and traffic data from Las Vegas Metropolitan area with the system dynamics model, the causal relationship and causal loop diagrams (CLDs) are introduced to analyze the cause-and-effect relationship and quantitative relationship between the factors of the combined system of land use and transportation, and then sub-models partition and system simulation are performed. The systems dynamics model is established by analyzing the relationship between a series of access management techniques, traffic characteristics, and land use features. The results show that system dynamics model can be used as an effective alternative to model the symbiosis relationship of land use and transportation system for urban planning and construction.Introduction


The utility model discloses a cyclone dust collector comprising a cyclone cylinder body, wherein the bottom of the cyclone cylinder body is inwards sunken; and a filtering net hole is formed in the inwards-sunken wall. According to the cyclone dust collector, the bottom of the cyclone cylinder body is inwards sunken to form an inwards-sunken structure, so that the normal cyclone separation is achieved; the axial length of the cyclone cylinder body is relatively shortened, thereby relatively increasing the dust collection space of the dust collector and obtaining a good effect which play an active practical significance to the dust collector (for example a handheld dust collector) with a smaller dust holding amount.


With the fast development of social networks, the massive growth of the number of multimodal data such as images and texts allows people have higher demands for information processing from an emotional perspective. Emotion recognition requires a higher ability for the computer to simulate high-level visual perception understanding. However, existing methods often focus on the single-modality investigation. In this work, we propose a multimodal model based on factorized bilinear pooling (FBP) and adversarial learning for emotion recognition. In our model, a multimodal feature fusion network is proposed to encode the inter-modality features under the guidance of the FBP to help the visual and textual feature representation learn from each other interactively. Beyond that, we propose an adversarial network by introducing two discriminative classification tasks, emotion recognition and multimodal fusion prediction. Our entire method can be implemented end-to-end by using a deep neural network framework. Experimental results indicate that our proposed model achieves competitive performance on the extended FI dataset. Progressive results prove the ability of our model for emotion recognition against other single- and multi-modality works respectively.


ABSTRACT This study explores dominant applications of graphic affordances in a sample of children-related charity appeals collected from the official websites of nine prominent Polish foundations in late 2016. It provides a systematic description of salient typographic and iconographic resources and an assessment of their rhetorical potential to solicit donations. The analysis focuses on three dominant discursive strategies used by charity communicators, namely how graphic affordances project utility (logos), confidence (ethos) and engagement (pathos). The article offers a critique of strategic emotional stimulation through aestheticized imagery and infantilizing graphics that replace arguments with connotators of 'normal' childhood. Such rhetorical practices generate a strong but incidental incentive to donate to 'deserving victims' motivated by moral superiority or 'warm-glow' altruism, but may not sustain the level of social capital indispensable to solidarity in charitable giving.


The title complex, [ZnFe2(C5H5)2(C8H9N3S)2]·0.5C4H8O, is a Schiff base chelate. It consists of one zinc cation and two ligand anions, the cation being tetrahedrally coordinated by one N atom and one S atom from each ligands, thus forming two orthogonal five-membered chelate rings related to each other by the twofold rotation axis passing through Zn.


INTRODUCTION The surface of Mars shows abundant evidence for sulfur activity over a prolonged period in martian history. Evidence goes back to the Viking landers in 1976 but more recent orbital and landed in situ missions, including the two MER rovers, which are still active, confirm this. The identification of the sulfate jarosite with ferric iron confirms highly oxidizing conditions near the martian surface. We speculate that conditions oxidizing enough to crystallize a SO4 containing scapolite exist in the lower martian crust or upper mantle. This scapolite could be a important reservoir for sulfate in Mars and might form either directly from sulfur-rich, oxidizing magmas or by metasomatism of previously crystallized plagioclase in basalt. CRYSTAL CHEMISTRY For a brief review of scapolite crystal chemistry see [1]. Most scapolites are solid solutions between marialite, Na4Al3Si9O24Cl and meionite, Ca4Al6Si6O24CO3 . However most terrestrial igneous scapolites have high sulfate contents and some approach compositions of Ca4Al6Si6O24SO4 which has the name silvialite [2] or may be more simply referred to as sulfate-Me [3] or in this abstract as SM. The most likely space group for ordered SM is tetragonal P42/n with two formula units per unit cell. The focus in these discussions is on the tetrahedral SO4 group which in space group P42/n occupies special position b (Wyckoff notation) and has site


The adsorption behaviors of antimony (III) by copper-zinc alloy filter media (KDF) have been investigated by batch and column experiments. In the batch experiment, the effects of KDF dosage, contact time, and solution pH on Sb(III) removal were examined. Under the optimum conditions, the removal percentage is over 95.0 % at room temperature. In the column experiment, the effects of flow rate, bed height, and some foreign ions on Sb(III) removal were explored. It was found that the removal percentage is over 95.0 % under the optimum conditions, and HCO 3 and CO 2 had positive effects on the Sb(III) removal, while Ca 2+ , Na + , Cl , NO 3 and SO 2 had negligible effects. Additionally the KDF column for Sb(III) removal could be repeatedly used three times and its removal ability could be effectively recovered by a simple washing process with water. KDF exhibits a good performance for the Sb(III) removal from contaminated waters.


In this note the experimental results of an analysis of the electromagnetic fields present in the productive area of new built oil-mill, placed in Bari district, considered representative of the majority of such a kind of the workshops in the Apulia region, are reported. Introductory study's purpose has been evidently to evaluate the exposure level of the workers during an oil production activity, inside a typology of transformation systems much spread on the Apulian territory that, even though with seasonal character, gives occupation to a big number of operators. Results of the tests highlight that inside the considered oil-mill there are not electromagnetic pollution risks for the operators during the period of maximum use of its productive capacities.

We have simulated a common envelope interaction of a 0.88-M$_{\odot}$, 90-R$_{\odot}$, red giant branch star and a 0.6-M$_{\odot}$, compact companion with the smoothed particle hydrodynamics code, Phantom, from the beginning of the Roche lobe overflow phase to the beginning of the self-regulated inspiral, using three different resolutions. The duration of the Roche lobe overflow phase is resolution dependent and would lengthen with increased resolution beyond the $\sim$20 years observed, while the inspiral phase and the post-common envelope separation are largely independent of resolution. Mass transfer rates through the Lagrangian points drive the orbital evolution during the Roche lobe overflow phase, as predicted analytically. The absolute mass transfer rate is resolution dependent, but always within an order of magnitude of the analytical value. Similarly, the gravitational drag in the simulations is close to the analytical approximation. This gives us confidence that simulations approximate reality. The $L_2$ and $L_3$ outflow observed during Roche lobe overflow remains bound, forming a circumbinary disk that is largely disrupted by the common envelope ejection. However, a longer phase of Roche lobe overflow and weaker common envelope ejection typical of a more stable binary may result in a surviving circumbinary disk. Finally, we examine the density distribution resulting from the interaction for simulations that include or omit the phase of Roche lobe overflow. We conclude that the degree of stability of the Roche lobe phase may modulate the shape of the subsequent planetary nebula, explaining the wide range of post-common envelope planetary nebula shapes observed.

In view of the existing problems,the paper proposes a series of corresponding measures in the hope of providing an important reference for sustainable development of ethnic traditional sports training base in Guizhou.


It is well-known that the vehicle stiffness has great influences on the vehicle dynamic performance. However, it is difficult to measure the objective effect of it in the vehicle dynamic standard test and to design it quantitatively. In this paper, the objective indicator "steering correction" which is the closed loop dynamic test and has relation with the vehicle stiffness is defined. Two relationships between the vehicle stiffness and the steering response and between the steering response and the steering correction are clarified by the new idea and the driving simulator. By combining these results, the objective relationship between the steering correction and the vehicle stiffness is clarified. Finally, the proto car made by using these relations achieved the top level of this performance.


Porous ethylcellulose (EC) film coating technique was used in preparing a capsule-type controlled release dosage form, in which theophylline (TP) was used as a poorly water-soluble model drug. The TP-loaded uncoated beads were spray-coated with an aqueous ethanolic or ethanolic EC solution, and the drug release characteristics and productivity of each product were examined. When the aqueous ethanol was used as the solvent of the coating solution, a large number of micropores were formed in the coating, and the porosity of coating and drug release rate could be controlled by altering the ethanolic concentration in the coating solution. In addition, few agglomerates were produced in the coating process, even though there was no anti-agglomeration agent in the coating solution. The drug release rate from the coated beads could be changed by film porosity as well as film thickness. Superposition analysis revealed that the EC-coated beads with different film porosities or different coating levels had the same drug release mechanism. It was further found that the drug release behavior of the porous EC film-coated beads was not affected by any simulated physiological conditions such as pH, surface tension, ionic strength or paddle rotation speed, indicating that in vivo drug release should not be affected by such physiological conditions in the gastrointestinal tract.


Concurrent positions is a political phenomenon that is very widespread nowadays in Indonesia, especially the concurrent ministerial positions from party cadres to even the general chairman of the party. This concurrent position results in the emergence of problems that are very vulnerable to abuse of power and conflicts of interest. The purpose of this study is to find out the arrangements for multiple ministerial posts based on article 23 of the law on state ministries, to find out Al-Mawardi's opinion on the issue of multiple positions, and to find out how the concept of an ideal ministerial position will be in the future. In this study the research method used by researchers is normative juridical, namely the statutory approach and the doctrinal approach. From a juridical perspective, the prohibition of concurrent ministerial positions has been regulated in Article 23 of law number 39 of 2008 concerning state ministries. But in that article the prohibition of holding multiple ministerial posts is not specifically regulated. Implicitly, Al-Mawardi explained that a minister must focus on devoting himself to the head of state in particular and the state in general. Because ministers must be the eyes and ears of the head of state, that is, they are required to be sensitive and observant about a problem that exists in that country. A minister must build integrity in the ministry to prevent the emergence of power instability. Therefore, an alternative concept for dealing with multiple ministerial positions can use a meritocracy system or zaken cabinet so that in the future ministers with ideal specifications will not result in conflicts of interest and abuse of power.Keywords: Concurrent positions, Minister, Constitutional, Al-Mawardi.


A focus of infection is a confined area that: (1) contains pathogenic microorganisms, (2) can occur anywhere in the body and (3) usually causes no clinical manifestations (1). A focal infection is a localized or generalized infection caused by the dissemination of microorganisms or toxic products from a focus of infection (1). These concepts have led to the Focal Theory of Infection (or Theory of Focal Infection) that postulates a myriad of diseases caused by microorganisms (bacteria, fungi, viruses) that arise endogenously from a focus of infection. Some have expanded this to include the environment via the concept of antigenic (molecular) mimicry or even to the extent that all diseases are caused by microbes (2, 3). Foci of infection have historically been postulated to arise from the tonsils, adenoids, sinuses and oral cavity with less common foci from the prostate, appendix, gall bladder and kidney (4, 5). Oral foci have traditionally been ascribed to pyorrhea alveolaris (periodontitis), alveolar abscesses and cellulitis, pulpless teeth, apical periodontitis, general oral sepsis and endodontically treated teeth with viridans group streptococci (VGS) being the principal metastatic microbial culprits (1, 4, 5). Focal infections attributed to foci of infection have included arthritis, neuritis, myalgias, nephritis, osteomyelitis, endocarditis, brain abscesses, prosthetic joint infections, skin abscesses, pneumonia, asthma, anemia, indigestion, gastritis, pancreatitis, colitis, diabetes, emphysema, goiter, thyroiditis, Hodgkin's disease, fever of unknown origin, stupidity and 'nervous diseases of all kinds' (1, 6–8). Currently, diseases postulated to be caused by microorganisms include cancer (9), sarcoidosis, multiple sclerosis, amyotrophic lateral sclerosis, autism, Guillain–Barré syndrome, pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS), Tourette's syndrome, myasthenia gravis, polycystic kidney disease, obesity, Alzheimer's disease, diabetes mellitus and, of particular interest to dentistry, cardiovascular disease (4, 10). Many of these are proposed to affect the host by antigenic mimicry: microbial antigens similar to host antigens that induce an immune response that damages host tissue (11). The classic pathway of focal infection is by direct spread via blood or lymphatic metastasis of the infecting microorganism, its toxic products or tissue-damaging immunologic reactions to the microorganism. Several characteristics consistently appear throughout the long history of focal infection: (1) theories of disease espoused by authoritative (some might say autocratic) individuals with little or no science to support their theses (doctrine without data), (2) consistent application of focal infection to diseases for which medicine has no good concepts of etiology and/ or treatment, (3) consistent and pervasive extrapolation beyond the data and (4) a common disregard for the accepted methodology of science (i.e. controlled studies). Often, the 'disregard syndrome' is apparent: the unintentional failure to cite previous scientific works, scorn for previous sound published data that is not considered 'cutting edge', apparently intentional disregard for already published data that does not conform or even contradicts the position espoused by the investigator or an unintentional lack of regard for relevant literature due to ignorance of the field being investigated (12). 'Reverse Investigation' is not uncommon: start with the conclusion and then gather only the facts that support it. The tendency to programmed conferences is common: only those who are of the samemind are invited and commonly leads to what Jane's Defense Weekly terms 'incestuous amplification': a condition in warfare where one only listens


The present invention refers to a conveying device and to a sewing machine comprising said device. The conveying device comprises a plate to be constrained to a base of the sewing machine, a conveyor belt mounted on two rollers constrained to a supporting structure so as to rotate, the supporting structure being coupled with the sewing machine, so that the conveyor belt is adjacent to the plate, and motor means connected with the conveyor belt and suited to put said belt in motion so that a cloth arranged between the plate and the conveyor belt translates when the conveyor belt is put in motion. The conveying device comprises at least a pressing element actuated by a piston of a cylinder which comprises elastic means and is constrained to the supporting structure of the conveyor belt, said cylinder being connected with a pressure control system. The pressure control system adjusts the pressure acting on the cloth to be conveyed since the elastic means are adjustable through the same system and the pressing element is in contact with the portion of the plate and/or belt.


Fe-based composite coatings reinforced with WC particulates were produced on 1045 carbon steel by thermal spray welding.The microstructure was characterized by means of scanning electron microscopy(SEM),field emission scanning electron microscopy(FESEM) and analysis of energy dispersive spectrometer(EDS).The abrasive wear behavior of the coatings was investigated under dry sliding wear conditions,and was compared with that of Fe-based coatings produced without the addition of WC.The results show that the microstructure of the coatings is compact with homogeneous distribution of WC particles,in which amount of finer carbides dispersed.The coating reinforced with WC exhibits a significant increase in wear resistance.


By reviewing the nurture from agriculture to industry and from rural areas to urban districts after the founding of New China,and by drawing on the experiences of reverse-nurture in the U.S,Japan and Korea as well,this paper aims to propose two kinds or levels of reverse-nurture: One is to get the support from both central and local governments,which can offer policies and financial support;the other is to depend upon the public,including people in cities,factories,businesses,etc.and arose their enthusiasm.Meanwhile,it becomes vital to provide extra help for countryside,agriculture and peasants.


Globalization and new economy has made the traditional mono-competition into a new pattern combined the competition and cooperation.Such competition is centered more and more among big cities that can reflect the national competitive power with national influence. Thepurpose of the study of urban competitive power by city planners is to improve the comprehensive competitive power of the city throughplanning so as to be in an advantageous position in the fight for global strategic resources in the new century.[


Genetic parameters and genotypic values of fruits from umbu-cajazeira clones were determined using the restricted maximum likelihood/best linear unbiased prediction (REML/BLUP) method, from the morphological, physicochemical and chemical characterization of fruits. The experiment was composed of six experimental clones, in three randomized complete block designs and three replicates per plot in an unbalanced arrangement in Ipanguaçu/RN, due to non-fructification of some clones of the experiment. Morphological, physicochemical and chemical characterization of 20 fruits of each clone was performed. The variance components for REML and medium components (BLUP), were estimated using the mixed model's method REML/BLUP. The three best clones selected were from Serra do Mel, Açu, and Carnaubais. The method used allowed selection of clones with high soluble solids content and pulp yield based on the genotypic value of clones. Fruit clones from Serra do Mel can be used for pulp processing or fresh consumption. The Açu clone showed a high pulp yield and is recommended pulp processing. Carnaubais, Alto do Rodrigues, and Ipanguaçu generated fruits for fresh consumption.


It is unlikely that Stoesz and Karger will be widely commended for the critique of social work accreditation. Social work academics do not usually handle criticism with equanimity. In some respects, their case is overstated. The problems associated with social work accreditation are not caused by the low publication productivity of social work faculty, nor by the low GRE scores of social work students. The primary purpose of social work education is to train practitioners, and faculty research productivity may be unrelated to this goal. There is an urgent need for research on the accreditation process in social work education.


We propose a model for glioma patterns in a microlocal tumor environment under the influence of acidity, angiogenesis, and tissue anisotropy. The bottom-up model deduction eventually leads to a system of reaction–diffusion–taxis equations for glioma and endothelial cell population densities, of which the former infers flux limitation both in the self-diffusion and taxis terms. The model extends a recently introduced (Kumar, Li and Surulescu, 2020) description of glioma pseudopalisade formation with the aim of studying the effect of hypoxia-induced tumor vascularization on the establishment and maintenance of these histological patterns which are typical for high-grade brain cancer. Numerical simulations of the population level dynamics are performed to investigate several model scenarios containing this and further effects.


The purpose of this study was to examine the effects of a self-monitoring intervention on teachers' direct behavior ratings of 3 students with traumatic brain injury. The authors used a multiple-baseline-across-participants design to evaluate the effect of the strategy on each child's classwork and classroom behavior. The self-monitoring strategy included 3 components: self-ratings, matching self-ratings and teacher ratings, and teacher feedback. Results indicated that the strategy improved performance for all three children, as well as self-monitoring accuracy. The authors discuss the implications for future research, including the need for a component analysis of self-monitoring treatments.
