Despite the increasing need of nanometer-scale accuracy in abrasive machining using ultrasmall particles such as abrasive jet and chemical mechanical polishing(CMP), the process mechanism is still unknown. Based on the background, research on the effects of various process parameters on the machined surface at abrasive machining was motivated and performed by using finite element analysis where the effect of slurry fluid flow involved. The effect of particle shape on the machined surface during particle-surface collision was discussed in this paper. The results from FEA simulation revealed that any damage or defect generation on machined surface by the impact may occur only if the particle has enough impact energy. Therefore, it could be concluded that generation of the defects and damage on the wafer surface after CMP process was mainly due to direct contact of the 3 bodies, i.e., pad-particle-wafer.


A 69 year old man was transferred to our hospital in January 1994 with facial edema and dyspnea on exertion. His condition had been diagnosed by bronchofiberscopy at another hospital as small cell lung cancer with obstruction of the right upper bronchus. After the fifth course of chemotherapy, he was asymptomatic for 3 months, and then his symptoms gradually worsened. A chest radiograph obtained on admission showed a right hilar mass and upper lobe atelectasis. Chest CT showed complete SVC obstruction due to a lesion and the presence of collateral veins (Fig. 1). Two-dimensional Doppler flow imaging was done with a 2.5 MHz transducer (Toshiba SSH-65A, Toshiba, Tokyo, Japan), and the SVC was visualized via the right supraclavicular fossa. The sample volume was positioned in the center of the SVC, and the sample depth was set at about 5 em. Figure 2 shows normal pulsed Doppler flow in the SVC. The pulsed Doppler sonogram of our patient showed a low flow velocity (12.8 cm/s) and turbulent flow in the SVC. Peak flow was seen during diastole (Fig. 3). After 30 Gy of radiotherapy, CT scans showed marked involution of the mass and slight opacification of the SVC (Fig. 1). An increase of the peak flow velocity and a reappearance of systolic flow in the SVC was seen on pulsed Doppler sonography (Fig. 3). At the completion of radiotherapy (total dose, 50 Gy), the symptoms of SVC syndrome were almost completely relieved. However, CT scans showed no significant changes in the SVC in comparison to the findings after 30 Gy (Fig. 1). On the other hand, we clearly observed both systolic flow (40.0 cm/s) and diastolic flow (35.8 cm/s) on pulsed Doppler sonography, the 5 wave velocity became higher


The purpose of a Trial Monitoring System is to provide a comprehensive suite where cases are created. Trial proceedings are monitored progressively to make informed decisions that include assignment of investigating entities and requesting advisors for opinions to take over the prosecution of the case. It provides a platform for applying counter petitions against an allegation's disposal and integrate proceedings in different levels of scrutiny and across tribunal entities. The outcome is the aggregation of such a data, to classify cases for statistical information and relaying the information in presentable format.


The growing need to perform surgical procedures, monitoring, and intervention of greater precision have led to the development of multimodal medical imaging systems. Multimodal images are a strategy to overcome the limitations of medical imaging technologies by combining the strengths of individual modalities or technologies. In this work, we propose a low-cost multimodal system that combines 3D freehand ultrasound with fringe projection profilometry to obtain information from the external and the internal structure of an object of interest. Both modalities are referred to a single coordinate system defined in the calibration to avoid post-processing and registration of the acquired images. The freehand ultrasound calibration results are similar to those previously reported in the literature using more expensive infrared tracking systems. The calibration reproducibility at the center point of the ultrasound image was 0.6202 mm for 8 independent calibrations. We tested our system on a breast phantom with tumors. Encouraging results show the potential of the system for applications in intraoperative settings.


Organic materials have become very important in recent years due to their potential use for photovoltaic applications. Among the main advantages of organic semiconductors are their functional and mechanical flexibility, as well as fabrication simplicity. However, these materials usually afford moderate efficiency in organic photovoltaic devices. On the other hand, hydrogenated amorphous silicon (a-Si:H) is a widely known inorganic semiconductor that compared to their organic counterparts has excellent photogeneration and transport properties and it is suitable for large area fabrication of flexible devices. The idea of combining organic semiconductors and amorphous silicon films in hybrid photovoltaic devices is very attractive due to the possibility to complement the useful properties of both material systems. The photovoltaic devices that we study in this work consist of a p-i-n structure, which is also commonly used in inorganic solar cells. In such kind of structures, the light is mainly absorbed in the intrinsic silicon film and the p- and ntype films are used to create an electric field that separates electrons and holes to produce a photocurrent. In this work, we use an organic material (PEDOT:PSS) to replace the p-type inorganic film in amorphous silicon p-i-n structure. It is widely known, that PEDOT:PSS based organic film is highly transparent and its conductivity can be modified e.g. immerse in a solvent type. Here we present the results of experimental investigation of the effect of isopropanol (IPA) treatments in p-type (PEDOT:PSS) organic layer on characteristics of hybrid solar cell structure.


The word 'rune' suggests not merely a form of writing, the angular characters of the old Germanic script long since discarded, but a whole world of mystery and magic: strange symbols scratched into ancient tools and weapon not lying idle in some museum show-case; names of warriors, secret spells, even snatches of songs, appearing on objects as diverse as minute silver coins and towering stone crosses, scattered in the unlikeliest places from Yugoslavia to Orkney, from Greenland to Greece. The word itself means 'mystery' and 'secret' in early English and its related languages. When Bishop Wulfila translated the Bible into fourth-century Gothic, he rendered St Mark's 'the mystery of the kingdom of God'(iv. 11) as 'rū na þiudangardjōs guþs'. When the chieftains and wise counsellors of Anglo-Saxon England gathered in conclave, men called their secret deliberations 'runes', as does the poet of the Old English Wanderer in a line weighty with wisdom and secrecy:


We estimated the psychosomatic development of 25 girls aged 13-19 years after antineoplastic therapy. Normal parameters of physical development were stated in all cases. No injury of central nervous system in all cases was seen. Psychological examination revealed strong suppression reactions and evident anxiety signs in majority of girls.


The use of overconvergent cohomology in constructing p -adic L -functions, initiated by Stevens and Pollack–Stevens in the setting of classical modular forms, has now been estab-lished in a number of settings. The method is compatible with constructions of eigenvarieties by Ash–Stevens, Urban and Hansen


Objective:To investigate the influences upon the behavior of obeying medical directions of diabetics by pointed health education. Methods:278 cases of diagnosed diabetics patients were randomly divided into the observation group (136 cases) and the control group (142 cases). The control group was given routine health education,but the observation group recepted the pointed health education. A questionnaire which was designed independently was used to investigate about related data in the two groups before and after health education to compare the patient's understanding rate of healthy knowledge and the initiative cooperating rate of obeying medical directions. Results:There were no significant differences on the patient's understanding rates of healthy knowledge before health education in the two groups (P0.05). After health education,the understanding rate was 100% and the initiative cooperating rate was 78% in the observation group,was higher than in the control group(P0.01). Conclusion:Not only the pointed health education could raise patient's level of healthy knowledge,but also could enhance the patient to obey the medical directions effectively.


In this paper we establish the existence of nonclassical entropy solutions for the Cauchy problem associated with a conservation law having a nonconvex flux-function. Instead of the classical Oleinik entropy criterion, we use a single entropy inequality supplemented with a kinetic relation. We prove that these two conditions characterize a unique nonclassical Riemann solver. Then we apply the wave-front tracking method to the Cauchy problem. By introducing a new total variation functional, we can prove that the corresponding approximate solutions converge strongly to a nonclassical entropy solution.


The dismal prognosis of patients suffering from astrocytomas, especially glioblastoma multiforme (GBM) emphasizes the need for more precise expressional characterization of these tumors in order to identify potential prognostic factors and therapeutic targets. Tumor growth leads to formation of low oxygenated regions that are considered as stem cell niches. GBM are described with high cancer stem cell content and with hypoxic and necrotic areas. This study investigates in astrocytomas WHO grade II to IV the transcript levels of genes expressed in cancer stem cells (NANOG, ALDH1A1, ALDH3A1, CD133, NOTCH1, ABCB1, ABCG2) and hypoxia regulators and regulated genes (HIF1α, HIF2α, CA9, VEGF). A relationship between some of these factors and patient survival or tumor grade has been reported in previous studies. Tissue samples (ts) from 46 patients were histologically graded as: 12 diffuse astrocytomas (DA) gr II, 6 anaplastic astrocytomas (AA) gr III and 28 GBM gr IV. RNA was isolated from ts. Gene expression levels measured by real-time qRT-PCR in the separate tumor samples were compared to levels found in 6 non-tumor ts from patients suffering epileptic lesions and to beta actin. Relative quantities were compared between ts groups by Mann-Whitney test and log-transformed for Pearson correlation calculation. Increase of HIF2α (200-fold), CA9 (2.7-fold) and VEGF (3.4-fold) mRNA was observed in GBM compared to non-tumor or DA (p 0.05). In contrast, a decrease of expression in GBM compared to DA of ABCB1 (10-fold), ABCG2 (10-fold), NOTCH1 (4.2-fold) and ALDH1A1 (6.8-fold) mRNA was observed (p Conclusion: Transcript levels of analyzed genes are significantly related to tumor grade, except are HIF1α and NANOG. Decreased transcript levels of genes expressed in cancer stem cells are in contrast to a high content of cancer stem cells described for GBM. Expression levels of most of the investigated genes can be considered promising candidates as prognostic and diagnostic markers in astrocytomas.

Statistical methods for automatically identifying dependent word pairs (i.e. dependent bigrams) in a corpus of natural language text have traditionally been performed using asymptotic tests of significance. This paper suggests that Fisher's exact test is a more appropriate test due to the skewed and sparse data samples typical of this problem. Both theoretical and experimental comparisons between Fisher's exact test and a variety of asymptotic tests (the t-test, Pearson's chi-square test, and Likelihood-ratio chi-square test) are presented. These comparisons show that Fisher's exact test is more reliable in identifying dependent word pairs. The usefulness of Fisher's exact test extends to other problems in statistical natural language processing as skewed and sparse data appears to be the rule in natural language. The experiment presented in this paper was performed using PROC FREQ of the SAS System.


In this work we study the well-known problem put forward by S. N. Bernstein in 1930. We construct an operator that converges and give a bound for the best convergence order.


Given the distance between every pair of 3 control points, and given the angle to every pair of the control points from an additional point called the Center of Perspectivity (P ), find the lengths of the segments joining the P to each of the control points. We call this the "perspective-three-point (p3p) problem". The corresponding algebraic equation system is called the p3p equation system. So-called a solution classification of the p3p equation system is to give explicit conditions under which the system has none, one, two, ... real physical solutions, respectively. This problem had been open for many years [11, 1-8]. An efficient algorithm is presented here for such a classification under some non-degenerate conditions that gives: • The condition under which the p3p equation system has a unique real physical solution.


A unitary matrix extension method of the corresponding vectors, obtained from multiple channellow-pass filters by polyphase factorization, is proposed. The extended matrix corresponding to multiple channelorthonormal wavelet filters is also obtained in this paper, which solves the problem of the general solutions of matrixextension associated with multiple channel orthonormal wavelet filters systematically.

Organic Rankine cycle (ORC) systems are gaining ground as a means of effectively providing sustainable energy. Coupling small-scale ORCs powered by scroll expander-generators with solar thermal collectors and storage can provide combined heat and power to underserved rural communities. Simulation of such systems is instrumental in optimizing their control strategy. However, most models developed so far operate at steady-state or focus either on ORC or on storage dynamics. In this work, a model for the dynamics of the solar ORC system is developed to evaluate the impact of variable heat sources and sinks, thermal storage, and the variable loads associated with distributed generation. This model is then used to assess control schemes that adjust operating conditions for daily environmental variation.Copyright © 2014 by ASME


Background: ETHE1 converts persulfides to sulfite in the mitochondrial sulfide oxidation pathway. Results: The kinetics of human ETHE1 and two mutants described in patients have been characterized. Conclusion: Both glutathione and coenzyme A serve as persulfide carriers for ETHE1, albeit with different efficacies. Significance: Low steady-state H2S levels are maintained by its efficient oxidation and patient mutations in ETHE1 impair this activity.


The purpose of this study was to investigate learning in communities of inquiry (CoI) as the terms are defined in Garrison, Anderson, and Archer's (2000) framework. We identified 252 reports from 2000—2008 that referenced the framework, and we reviewed them using Ogawan and Malen's (1991) strategy for synthesizing multi-vocal bodies of literature. Of the 252 reports, 48 collected and analyzed data on one or more aspects of the CoI framework; only five included a measure of student learning. Predominantly, learning was defined as perceived learning and assessed with a single item on a closed-form survey. Concerns about the soundness of such measures pervade the educational measure m e n t community; in addition, we question the validity of the particular items employed in the CoI literature. Bracketing these concerns, the review indicates that it is unlikely that deep and meaningful learning arises in CoI. Students associate the surface learning that does occur with independent activities or didactic instruction; not sustained communication in critical CoI. We encourage researchers to conduct more, substantial investigations into the central construct of the popular framework for e-learning and theorists to respond to the mounting body of disconfirming evidence.

Image forgery detection plays a vital role for thorough incident investigation and social media crime preventions. An innovative approach for image forgery detection by utilizing a DenseNet-201 convolutional neural network is presented. The proposed method utilizes DenseNet-201 architecture to extract features from an input image and then uses a fully connected layer to classify the image as either genuine or forged. The model is trained on a dataset of authenticated and forged images and evaluated on a separate test set. The results show that the proposed approach achieves an accuracy of 94.12 %, outperforming existing methods. It demonstrates that the proposed model can accurately detect image forgeries across a wide range of image types. Also, the model is evaluated on various image transformations, like scaling, rotation, and translation. Furthermore, the proposed approach is computationally efficient, making it suitable for real-time applications.


It is found No.3 steam turbine of 60 MW unit of some power plant is of low vaccum when being put into operation after overhaul under the same load.Therefore,this paper analyzes factors affecting vaccum of its condenser and considers the main reason for reduction of vaccum is air leakage of the vaccum system and smudgy heating area of the condenser.By leak test for vaccum,it confirms leakage of the vaccum system.Through pressure adjustment test for shaft seal it excludes possibility of leakage of the shaft seal system.After finding out leakage point by irrigation test for the steam turbine,it suggests to adjust backwash interval and rubber ball input way of the condenser and plug leakage point of the vaccum system to eliminate the leakage point.Once more input operation of the unit shows that vaccum recovers to be normal.


One of the learning media that needs to be developed is the powtoon application-based learning media. This basic concept puts the idea of the teaching and learning process using animated videos. The purpose of this research is to determine the results of the powtoon application-based learning process in science lessons about energy, in fourth grade elementary schools. The use of this media is very effective during these times because when the researcher began her research about the usage of this media, home learning was being carried out due to Coronavirus outbreak (Covid-19), so the teaching and learning process was carried out using the internet. The research method used survey method of research, using the ADDIE development model. The learning media test was carried out by 3 media experts, 3 subject experts and 3 teachers from different schools. The product trials were conducted by 79 students from three different schools. The data was collected using the Likert scale with a range of score from 1 to 5. The results of this research show that the powtoon application-based learning media is very good for teaching and learning in schools about energy in elementary schools, because the Powtoon application is able to develop students' imagination and common sense in learning thus increasing their learning achievement. Further research by combining learning strategies during the pandemic through online learning.


Abstract Two series of sea surface temperature observations reported for Station P (50°N, 145°W) during the period 1952–65 are compared. One series consists of either engine intake or surface bucket temperature measurements (TS) and the other consists of surface bathythermograph temperatures (TB). Estimates of the monthly mean sea surface temperature from these two series differ by up to 1.04°C. The difference (Ts−TS) is time dependent, changing from positive during 1952–53 to negative in 1954–56. Only since 1956 have the annual mean differences been less than the accepted accuracy of the measurements (±0.2°C). The minimum difference occurs in summer with the maximum in winter. There are occasional significant effects on the annual mean difference due to the type of ship operations, that is, whether hydrographic observations are carried out.


BshC is the final enzyme in a three step pathway for the synthesis of bacillithiol, a compound that enables resistance to fosfomycin in Gram-positive bacteria. BshC is unique from other enzymes of its kind because of an additional ADP binding site and inactivity when studied in the laboratory. To explore BshC function, several site-directed mutants have been selected within the ADP binding pocket. Fluorescence assays have been utilized on the wild-type BshC and one mutant, Y510Q. We determined that Y510Q does not bind ATP as effectively as wild-type BshC. These fluorescence assays will be utilized on W506L, E384A, and H386A mutants and structural analysis of all the mutants will be initiated. Gaining more understanding of the structure of these mutants and how they bind ATP will give a better understanding of how BshC binds its substrate, which will allow the development of inhibitors to combat fosfomycin resistance. Low molecular weight (LMW) thiols play an important role in maintaining redox balance and detoxifying xenobiotic agents in cells. Examples of these LMW thiols are mycothiol (MSH) and bacillithiol (BSH) (Scheme 1). The LMW thiols, MSH and BSH, are similar in shape and function; however, there are some differences. MSH is a molecule produced and used by mycobacteria, while BSH is a molecule that is produced by some pathogenic Grampositive bacteria like Staphylococcus, which causes skin infections, and Bacillus anthracis, which causes anthrax. The drug Monurol is commonly used to treat such infections, as well as being commonly prescribed for urinary tract infections; the active ingredient being fosfomycin. Fosfomycin is a compound that inhibits the biogenesis of the pathogen's cell wall. The problem at hand is these bacteria are resistant to the drug, due to their production of the compound Scheme 1 The structure of bacillithiol (BSH)


In the globalization era, social media is very popular in various circles, both in young people and elderly. And nowadays, social media has an important role in the human's life. There are two Social Media which have many users, namely, Facebook and Instagram. Facebook is a kind of social media that has been used by many people in Indonesia. Instagram is a social media that usually used by the users for share a picture, photo and video that added by caption on it. This study was used qualitative method using sociolinguistics approach. The study objects were status and captions on Facebook and Instagram which was indicated include on the criteria material object of the study analysis. The statuses were taken from Facebook's post, while the captions were taken from Instagram's post. This study has identified the relation of the Language use especially English in Facebook and Instagram based on the sociolinguistics approach; age, gender, and educational background. The findings showed that age has an influence on the use of language both formally and informally. Young netizens tend to use informal or slang language. Gender has an impact to the use of English language. The study showed that women's netizen more polite in using the language than men.  On the other hand, men tend to use language that seems outspoken and without any boundaries. Educational background has an influence to the use of English language in social media especially Facebook.  The study has attempted to show the variations of English used by the Indonesian netizens from different age, gender and educational background.


This paper draws parallels between speech recognition of one speaker on a limited set of words and recognition of tactile sign language.

Marriage is considered valid if it has fulfilled the terms and conditions of marriage. Among the pillars of marriage are the consent and kabul. Based on the law of origin, the ulama agreed that the consent came from the bride, while the Kabul came from the groom. However, in the matter of ittishal between the consent and the marriage contract, the scholars have different opinions. If there is no ittishal between the consent and the marriage ceremony, then the contract is still considered valid while it is still focused on the contract procession and not for a long time. The objectives of the research are, (1) knowing and analyzing the opinion of Shaykh Nizhamuddin Al-Balkhi about ittishal between consent and kabul in the marriage contract, (2) knowing the basis of the legal arguments used by Shaykh Nizhamuddin Al-Balkhi regarding ittishal between consent and kabul in the marriage contract, and (3) knowing the ijtihad method used in his istimbath al-hukminya. In this thesis research the writer uses qualitative research methods, namely research methods that produce descriptive data in the form of words or written utterances from people or observed behavior. This type of research is a research library. The results showed, 1) The law of ittishal between consent and the marriage of marriage according to Shaykh Nizhamuddin Al-Balkhi in the fatawa al-hindiyyah book that ittishal between ijab and kabul nikah is only fi majlisin wahidin. The ittishal of the marriage contract that is valid in Indonesia is regulated in the Islamic Law Compilation (KHI) in article 27: consent and kabul between the guardian and the prospective groom must be clear in sequence and not intermittent. 2) The legal basis used by Shaykh Nizhamuddin Al-Balkhi in the matter of ittishal between consent and kabul akad nikah, namely the hadith of the Prophet narrated by Abu Dawud. 3) The ijtihad method used by Shaykh Nizhamuddin Al-Balkhi is qiyas. Shaykh Nizhamuddin al-Balkhi confirmed that the marriage contract was one majlis but did not work with the marriage contract that was represented and in a different place with the condition that there must still be witnesses.


The structure of a newly synthesised solvated compound, 1,2,3-tris(4-quinolyl)cyclopropane, C 30 H 21 N 3 , has been analysed by X-ray diffraction (monoclinic, space group C2/c, a = 26.194(4) A, b = 7.912(2) A, c = 23.830(4) A, β = 96.11(3)°, Z = 8, V = 4910.6(3) A 3 ). Its structure was partly solved by direct methods and refined by molecular dynamic and least squares procedures on 2816 reflections to final R = 0.053. The general features of the trans conformation of quinoline rings obtained by molecular modelling is in agreement with the X-ray model. However, it fails to predit the orientations of quinoline planes and the C-C-C angles connecting the quinoline rings to the cyclopropane group. Presence of solvent molecules, still not clearly identified, and others factors inducing these discrepancies are discussed.


This paper presents a novel and fully automatic technique to estimate depth information from a single input image. The proposed method is based on a new image classification technique able to classify digital images (also in Bayer pattern format) as indoor, outdoor with geometric elements or outdoor without geometric elements. Using the information collected in the classification step a suitable depth map is estimated. The proposed technique is fully unsupervised and is able to generate depth map from a single view of the scene, requiring low computational resources.


Abstract The article analyzes the institutional policies of the UFSCar and their repercussions in the evaluation and management practices based on the current processes of reconfiguration of the evaluation and regulation policies and procedures of Brazilian higher education, in the context of the Program of Support for Restructuring and Expansion Plans of Federal Universities (Reuni). From a documental study and semi-structured interviews with institutional agents, it takes as object of study the control mechanisms, having as categories and subcategories: contractualization procedures (definition of goals); institutional policies (actors: roles and responsibilities; management actions); and performativity (regulatory processes; distance control; evaluation processes; and accountability). The results indicate that, despite the convenience of UFSCar's adherence to Reuni, due to the compatibility of the objectives of expansion and the managerial model adopted, the program ended up intensifying mechanisms of the New Public Management that were already present in the management of the university. This had a direct impact on the management of the institution: the internal bureaucracy incorporated external control mechanisms, meeting the demand for distance control, generated new demands and emphases, creating new administrative problems, and making explicit some of the university's deficiencies from its expansion process through Reuni.


The Tuyon basin is located near the crossing of the Tien Shan orogenic belt, the Western Kunlun fold system and the TarimAlashan blocks. The crossing of two lithospheric scale fault, the Talas-Ferghana dextral strike-slip fault and the NE extended South Tien Shan strike-slip fault, is just at the southern margin of the Tuyon basin. Therefore, many geoscientists all over the world have been attracted to petrogenesis of the Cenozoic basaltic volcanic rocks in the Tuyon basin and their tectonic implications. According to previous researches, the basalts emplaced within the Tuyon basin are of two units, the lower basalts and the upper basalts, aged 120~110 Ma and 70.4~36.6 Ma respectively. All these basalts are classified as alkali series, enriched in potassium, and considered as a result of a small plume probably rooted at a shallow level in the asthenosphere. Our new works on the igneous rocks in the Tuyon basin suggest that the so-called lower basalts are preserved as a series of cone dikes, which are emplaced in Jurassic-Lower Cretaceous sedimentary rocks; the upper basalts are formed as a series of volcanic eruptions, including calderas, ring dikes, necks and volcanic cones. For example, there are three volcanic cones in the line between the Kuvt cone and Bilebluk cone. We have discovered basaltic intrusive units in Jurassic sandstone and conglomerate strata. The basaltic extrusive units have the same occurrence with the early Cretaceous sediments, but uncomfortably overlain by the Paleogene sedimentary rocks. Therefore, the Tuyon basin is a compound volcanic basin, including series of volcanic eruptions with lavas and subvolcanic rocks, rather than it has two-layer structure consisted of two igneous units. Our investigations indicate that the basaltic rocks are mainly of dark gray, massive structure and porphyritic texture. The basaltic extrusive rocks are developed as columnar joint structure, vesicular structure and amygdaloidal structure. Most of volcanic rocks within Tuyon basin contain phenocrysts such as olivine, clinopyroxene and plagioclase, and occasionally phlogopite, amphibole and apatite. Olivine belongs to chrysolite circled by fine-grained aggregate of magnetite and talc. Most of olivine phenocrysts have been altered into iddingsite and talc. The clinopyroxene mainly belongs to augite, which characterize hourglass structure and zoned texture. The plagioclase phenocrysts have more content of anorthite. They are mainly andesine and occasional labradorite, but rare in zoned texture. The matrix minerals are clinopyroxene, plagioclase, magnetite and volcanic glass, and mainly formed tholeiitic texture, occasionally intergranular texture and vitrophyric. Therefore, the Cenozoic volcanic rocks in the Tuyon basin show characteristics of alkali series, and suggest that the region may was at extensional condition. In the Arhesaiordy volcanic-sedimentary sequences there are five basaltic sills intruded into the Jurassic sedimentary deposits. Many megacrysts have been found in the lowest basaltic layer, such as augite, phlogopite, amphibole and anorthoclasite. From the same layer we have collected lots of the deep-seated xenoliths including peridotite, granulite, pyroxenite, gneiss and so on. In the other four layers, the number of megacrysts and deep-seated xenoliths has been decreased quickly. There are also lots of deep-seated xenoliths in the Tasgeler caldera. Therefore, basaltic magma has the characteristics of rapid ascent. Consequently, the basaltic volcanic rocks in the Tuyon basin are formed direct from primary magma, which is rare affected by fractional crystallization.


In this paper we introduce a notion of discrete time into the c ognitive robotics languages of the Golog family. Our variant of Golog , namedChronolog, is achieved in a rather straightforward manner but we show that it allows one to express a rich variety of temporal concepts. It is based on exogenous tick actions generated by an external "clock" and a special functional fluent to keep track of the passing of time. Moreover, we consider on-line and off-line versions o f our proposal as well as real-time and reactive variants and the ability to deal with exogenous actions.


This paper presents the system configuration and control schemes of a USBS (uninterruptible secondary battery system), which acts as a battery energy storage system when no fault occurs in a commercial power network and functions as a UPS in case of network faults. If a fault such as a voltage interruption occurs on the network, the USBS disconnects critical loads from it instantly, and supplies power to them as a UPS. It takes less than 2 ms to restart supply power to the loads in case of an emergency, so no damage occurs. Simulations and experimental tests are carried out to confirm the feasibility of the proposed system.

Adversaries or internal threats wishing to exfiltrate sensitive data may choose a method that obfuscates the fact that a transfer is even taking place by camouflaging it inside of allowable data. This technique is known as steganography, which is the practice of concealing data (such as hidden communications or sensitive data of any kind) in an existing data transfer medium, such as images or video. Video streams may be targeted more readily than other media because of the bandwidth they offer compared to single images. Current methods for mitigating the risk associated with data exfiltration through steganography sanitization through unconditional alteration video frames. However, these approaches are limited as they do not detect if a steganography attack is occurring. Deep Neural Networks (DNNs) excel at pattern recognition, presenting an opportunity to leverage them for detection of steganography. Having the capability to detect steganography could prove extremely useful, with uses such as prompting security administrators to investigate further or to immediately halt a video stream. We investigate Least Significant Bit Steganography with both encrypted and cleartext payloads and show that machine learning can detect both.

One of the important vectors in development of Shanghai Cooperation Organization (SCO) became the international scientific and scientific-technological collaboration. However, this vector is not fully developed due to not only legal, organizational or financial issues, but also factors affecting communication between the subjects of cooperation in scientific or scientific-technological spheres, as well as defining accessibility and mobility of the knowledge market. In this case, it refers to the language of scientific communication used in international scientific and scientific-technological collaboration (communicative factors), and the development of education and academic mobility (educational factors) in SCO member-states. The conclusion is made that the effectiveness of international scientific and scientific-technological collaboration between the countries of Shanghai Cooperation Organization drops due to controversial policy and normative legal regulation with regards to the language used in scientific and scientific-technological communication, as well as with regards to development of higher education and academic mobility between the SCO countries. The author underline the need for further unification of national legislation of SCO member-states pertaining to the use of one or another language as the means of international scientific communication, requirements to preparation of academic staff, creation of relevant programs of students' academic mobility, and development of generally accepted educational standards.


This study aimed to investigate the current situation of toothbrushing guidance with child care teachers in day care facilities caring and managing infants and young children and to grasp problems neglected in using toothpaste and guiding toothbrushing to provide basic data for measures to cope with them. This study included 165 child care teachers or teachers of the kindergartens who agreed with its purpose. By excluding 10 questionnaires with omitted or conflicting answers, 156 ones were finally analyzed in this study. The correlation between education about oral health and toothbrushing guidance, the subjects with and without the experience of the education did not show any significant difference in time to encourage toothbrushing, behaviors of toothbrushing guidance, guidance on prevention of toothpaste intake and perception of an appropriate amount of toothpaste (p>0.05) while perception of the importance of oral health was significantly related with the education on oral health (p<0.05). Therefore, education system for specialists in oral health to offer a specific and systemic education and oral health education programs for child care teacher, are considered to be necessary.

Hunan Province is the country's a big agricultural province, but has the relatively low level of agricultural modernization, Development of digital agriculture has important theoretical and practical significance. In this paper, the development of digital agriculture in resent ten years in Hunan Province is discussed. Besides, some problems were pointed out and their corresponding development strategy was proposed.


Non-linearity and dynamics are very common in contemporary industrial processes, but the performance of traditional PCA methods is poor in these fields. In recent years, many scholars have proposed lots of methods to solve these problems. For dynamic processes monitoring, scholars expand the dimension by adding historical data to the original data, so that the established model contains time series information, but the actual monitoring performance is not satisfactory. In the field of nonlinear process monitoring, the kernel method is one of the effective strategies, but there are also many defects such as inconvenience of nuclear parameter setting. In this work, we propose a new monitoring algorithm-innovation neural component analysis (INCA). First, the dynamic and static structures are separated through the Autoregressive model. Then considering the effectiveness of the artificial neural network for nonlinear feature extraction, it is adopted to extract the features, which contain the main information, to construct statistics and finally realize the effective monitoring of dynamic nonlinear process. Simultaneously, we designed a set of mathematical experiments to verify the effectiveness of the method.

Near-vessellessness was induced in the secondary xylem of Ephedra campylopoda C. A. Mey. by mechanical bark blocking or by wounding. Both treatments resulted in regions of near-vesselless xylem. Xylem formed after the mechanical bark blocking also had regions in which the orientation of the axial components was changed from axial to lateral. Since either mechanical arrest of phloem and cambial transport or wounding of the cambium almost stopped differentiation into vessels, and instead induced differentiation into tracheids, it seems that the developmental signal for tracheid differentiation is not the same as that for vessels. The possible regulation of near-vessellessness in Ephedra is discussed.


We prove that the solution to the singular-degenerate stochastic fast-diffusion equation with parameter $m\in (0,1)$, with zero Dirichlet boundary conditions on a bounded domain in any spatial dimension, and driven by linear multiplicative Wiener noise, exhibits improved regularity in the Sobolev space $W^{1,m+1}_0$ for initial data in $L^{2}$.


A blended approach where pre-service and in-service professionals attend the same professional development event has the potential to create a leadership learning community. Bidirectional opportunities can result from a professional development format where experienced in-service professionals spend time with pre-service professionals. Public schools and universities can play a part in providing valuable resources to the community. This study shares how a leadership learning community was created by blending professional development to serve the needs of pre-service graduate students and in-service professionals in the field of early childhood education.


been several attempts to demonstrate the ~ v_; Aexistence of ultimately simple objects by purely logical methods. One of the most recent of such .l .) ~attempts forms part of the foundation of Witt'/_', i genstein's logical doctrine. As Wittgenstein has, until quite recently, been considered the authoritative source of Logical Positivism, an examination of his supposed demonstration of logical simples is propaedeutic to an evaluation of the method of the school. The doctrine of logical simples is fundamental to the philosophy of Logical Positivism. The two principal aims of that philosophical movement are: to present science with a secure logical foundation, and to eliminate metaphysics from all significant discourse.' In order to do these things it is necessary to show by logical analysis that there is only one complete analysis of any given proposition, and that this analysis is absolutely terminated in the discovery of elementary propositions which are directly and solely concerned with immediate experience. The doctrine that ultimate simples exist is required to insure the completeness and uniqueness of any given analysis. The doctrine can either be assumed, or demonstrated, or introduced as an arbitrary


. Differential cross-section of the 16 O + 12 C elastic scattering at E lab = 132, 181, 200, 260, 300, 608 and 1503 MeV has been reanalyzed in the framework of double-folding cluster (DFC1) potential over a wide angular range which cover both diffractive and refractive regions. Based upon the α -cluster structure of both colliding nuclei, the real DFC1 optical potential has been generated by using α - α effective interaction and new cluster modified Gaussian (CMGD) of target and projectile has also been extracted. Successful descriptions of the data were obtained over the full measured angular range at all considered energies. The results have been compared with the findings obtained by using the phenomenological approach as well as experimental data. Furthermore, the consistency between the real and imaginary volume integrals is checked by the dispersion relation and the total reaction cross-section has also been investigated.


"Nickoson and Sheridan's Writing Studies Research in Practice is a brilliant collection of original essays that together chart a promising future for inquiry in our field, all while paying critical attention to the consequences of inquiries past. In short order, Writing Studies Research in Practice will become required reading across the field—and will remain so for years to come." —Peter Mortensen, University of Illinois at Urbana-Champaign


This paper argues that a comparative study of trade union movements in South Africa and South America reveals interesting similarities, particularly in relation to "political" trade unionism. It is argued that the historical development and nature of trade union organisation in South Africa follows more closely the patterns in the more industrialised countries of South America (Chile, Brazil and Argentina) than those of tropical Africa. An important reason for this, it is suggested, is that relatively similar patterns of industrialisation were followed. These include the early industrialisation of the late 1800s, the beginnings of import substitution industrialisation between the wars and post‐1945 dependency on transnational corporations. and their emergent mass production industries. Further broad economic, political and ideological factors which shape the form of militant, socialist‐orientated trade unionism in these countries are considered. The paper attempts to identify similar patterns while not ig...

A. | Abstract: Depth grading of magnetic anisotropy in perpendicular magnetic media has been predicted to reduce thefield required to write data without sacrificing thermal stability. To study this prediction, we have producedCo/Pd multilayers with depth-dependent Co layer thickness. Polarized neutron reflectometry shows that thethickness grading results in a corresponding magnetic anisotropy gradient. Magnetometry reveals that theanisotropy gradient promotes domain nucleation upon magnetization reversal - a clear experimental demonstrationof the effectiveness of graded anisotropy for reducing write field.


In this dissertation I enquire into the status, scope and limits of human knowledge, given the fact that our perceptual and cognitive faculties are the product of evolution by natural selection. I argue that the commonsense representations these faculties provide us with yield a particular, species-specific scope on the world that does not 'correspond' in any straightforward way to the external world. We are, however, not bound by these commonsense representations. This particular, species-specific view of the world can be transgressed. Nevertheless, our transgressing representations remain confined to the conceptual space defined by the combinatorial possibilities of the various representational tools we possess. Furthermore, the way in which we fit representations to the external world is by means of our biologically determined epistemic orientation. Based on the fact that we are endowed with a particular set of perceptual and cognitive resources and are guided by a particular epistemic orientation, I conclude that we have a particular cognitive relation to the world. Therefore, an accurate representation for us is a particular fit (our epistemic orientation) with particular means (our perceptual and cognitive resources). iii Stellenbosch University http://scholar.sun.ac.za

This article aims to clarify the geographical transformation of Arab media and understand contemporary Arab media dynamics with a focus on satellite channels. After the 1970s, many Arab media publishers, initially operating in Europe, became infl uential actors in the Arab media scene. Since then, Europe has been regarded as a harbor for the freedom of speech. These media with headquarters outside of the Arab world, mainly in Europe, are referred to as 'offshore media.' The offshore media phenomenon and its consequence, the geographical division of Arab media discourse between the Arab world and Europe, were regarded as an essential characteristic of Arab media. However, after the mid-1990s, the development and proliferation of satellite television prompted the return of Europe-based Arab media companies, particularly satellite channels, to Arab countries, and this geographical division was dissolved. Now, most of the pivotal Arab satellite channels broadcast not from Europe but from within the Arab world. Importantly, in accommodating these previously Europe-based media channels (and a number of newcomers), a phenomenon called the 'media city' has played an important role. Some consider these media cities as the new harbors for freedom of speech, an alternative to the role previously played by Europe. This article will trace the geographical transformation of Arab media historically, with particular focus on the decline of offshore media and the rise of the media cities. Furthermore, through the analysis of three media cities in Egypt, Jordan, and the UAE, this article will suggest that the media city can function not only as a substitute for Europe, but also as a key device for promoting and maintaining the diversity and multiplicity of contemporary Arab media.


The effects of yttrium and cerium on microstructures and properties of Nb-Si system composites were investigated by scanning electron microscopy( SEM), energy dispersive spectrum(EDS), X-ray diffraction(XRD) and high temperature oxidation experiments.It is found that the coarse primary silicide phase became finer and more homogeneous with Y and Ce addition.The results of high temperature oxidation experiments show that the oxidation rates of NbSi system composites with an appropriate amount of Y and Ce decrease compared with those of alloys without Y or Ce addition, and oxidation products mainly distribute along the phase boundaries between the Nb solid solution and silicide.

The use of sprinkling with ventilation to cool dairy cows is considered an appropriate practice to reduce the negative effects of heat stress. However, due to climate change, water will increasingly become a limited resource, so we need to make water use more and more efficient. For this purpose, an active drying sensor has been developed in order to time the sprinkling cooling system. The sensor reproduces the thermal response of a cow, considering both sensible and latent heat exchange, and is located in the feeding alley, about two meters above the floor. This allows the fabric of the sensor (simulating the fur) to be wetted by the sprinkler, and blown by the fan. The water content of the sensor fabric during the drying time is monitored by measuring its electrical conductivity, allowing the estimation of the time the fur becomes dry. Another two specifically designed instruments are presented, the first to estimate the fur's water content after spraying, and the second to detect the time the fur became dry. Sensor output, interpreted through a simplified model, gave a predicted drying time with an error ranging between −11.4% and +14.8% (R2 = 0.789). In the commercial barn where the experiments were conducted, the use of the sensor allowed an estimated reduction in water consumption of about 57%, with respect to the fixed timing normally used. As a perspective, the sensor could be used to assess cows' heat stress level.


Correlative light and electron microscopy (CLEM) combines two imaging modalities, balancing out the limits of one technique with the other. In recent years, Focused Ion Beam Scanning Electron Microscopy (FIB-SEM) has emerged as a flexible method that enables semi-automated volume acquisition at the ultrastructural level. We present a toolset for adherent cultured cells that enables tracking and finding cell regions previously identified in light microscopy, in the FIB-SEM along with automatic acquisition of high-resolution volume datasets. We detect a grid pattern in both modalities (LM and EM), which identifies common reference points. The novel combination of these techniques enables complete automation of the workflow. This includes setting the coincidence point of both ion and electron beams, automated evaluation of the image quality and constantly tracking the sample position with the microscope's field of view reducing or even eliminating operator supervision. We show the ability to target the regions of interest in EM within 5 µm accuracy, while iterating between different targets including unattended data acquisition. Our results demonstrate that executing high throughput volume acquisition in electron microscopy is possible.


Synthetic composite materials constructed by hybridizing multiple components are typically unsustainable due to inadequate recyclability and incomplete degradation. In contrast, biological materials like silk and bamboo assemble pure polymeric components into sophisticated multiscale architectures, achieving both excellent performance and full degradability. Learning from these natural examples of bio-based "single-component" composites will stimulate the development of sustainable materials. Here, we report a single-component "Silk nacre," where nacre's typical "brick-and-mortar" structure has been replicated with silk fibroin only and by a facile procedure combining bidirectional freezing, water vapor annealing, and densification. The biomimetic design endows the Silk nacre with mechanical properties superior to those of homogeneous silk material, as well as to many frequently used polymers. In addition, the Silk nacre shows controllable plasticity and complete biodegradability, representing an alternative substitute to conventional composite materials.


The multi-row perforated concrete wallboard with built-in sound insulation materials studied in this paper is a new type of lightweight sound insulation wall. With reference to the authorized utility model wall, this work performs sound isolation tests on walls with different internal structural parameters cast on multiple sections, using the experimental method of sound insulation room. Based on the experiment, COMSOL numerical simulation software is used to establish a sound-solid multiphysics model to achieve the numerical solution. Three kinds of changing parameters are studied with respect to the effect of the sound transmission on the wall panel. The optimal cross-section combination structure discovered is a foam concrete wall panel with a 15mm thick sound insulation layer, multiple rows of 30 mm diameter holes and a large flow resistance.


Goals of the project 5G ESSENCE (Grant Agreement No.761592) "addresses" the paradigms of Edge Cloud computing and Small Cell-as-a-Service (SCaaS) by fuelling the drivers and removing the barriers in the Small Cell (SC) market, forecasted to grow at an impressive pace up to 2020 and beyond, and to play a "key role" in the global 5G ecosystem. The original 5G ESSENCE framework proposes and designs a highly flexible and scalable platform, able to support new business models and revenue streams by creating a "neutral host" market and reducing operational costs, thus providing new opportunities for ownership, deployment, operation and amortisation. The technical approach exploits the benefits of the centralisation of Small Cell functions as scale grows through an edge cloud environment based on a two-tier architecture, that is: (i) a first distributed tier for providing low latency services, and; (ii) a second centralised tier for providing high processing power for computing-intensive network applications (more details are also given in Figure 2). This allows decoupling the control and user planes of the Radio Access Network (RAN) and achieving the benefits of Cloud-RAN without the enormous fronthaul latency restrictions. The use of end-to-end (E2E) network slicing mechanisms will allow sharing the 5G ESSENCE infrastructure among multiple operators/vertical industries and, consequently, customising its capabilities on a per-tenant basis. The versatility of the architecture is enhanced by high-performance virtualisation techniques for data isolation, latency reduction and resource efficiency, and by orchestrating lightweight virtual resources enabling efficient Virtualised Network Function (VNF) placement and live migration. The 5G ESSENCE project leverages knowledge, SW modules and prototypes from various 5G-PPP Phase-1 projects (with the "SESAME" project 1 being particularly relevant). Building on these foundations, very ambitious objectives are targeted, culminating with the prototyping and demonstration of 5G ESSENCE system in three real-life use cases associated to vertical industries, that is: (i) Edge Network Acceleration with local video production and distribution in a crowded event; (ii) Mission Critical (MC) applications for Public Safety (PS) communications providers, and; (iii) In-Flight Entertainment and Connectivity (IFEC) communications, as depicted in Figure 1.


Precociously bright Kwiatkowski won a scholarship to Exeter College, Oxford, to study philosophy, physiology, and psychology at the age of 16. Too young to take up his place, he completed a one year student apprenticeship with Leyland, manufacturer of lorries, buses, and trolleybuses. As a boy, influenced by his engineer father, he was intrigued by how systems worked. His practical bent finally nudged him into medicine.

SLQ and DLQ analysis, average contribution, growth rate and shift share analysis have been done to observe contribution, competiveness and progresive growth of economic sector. Based on the assesment by scoring of the criteria, leading economic sector was determined and found that education service sector lead the rank followed by information and communication sector.


The ionophore X-537 A facilitates the permeation of calcium through membranes. Human platelets exposed to X-537 A undergo a release of serotonin, which has been attributed to an increase in the concentration of cytoplasmic calcium, mediated by X-537 A. However, at a low concentration of X-537 A, platelets release serotonin but one cannot observe a release of heparin-neutralizing activity (PF4) and adenine nucleotides, an activation of clot-promoting activity (PF3), or a significant uptake of 45calcium into platelets. Electron micrographs of platelets after exposure to X-537A do not exhibit the alterations known to be coupled with the release reaction, despite a considerable release of serotonin. Two-phase partition studies demonstrate that X-537A is able to extract serotonin into an organic phase. In summary, these results indicate that X-537A causes a selective release of serotonin by transporting it through membranes. Only at high concentrations of X-537A can one establish an uptake of 45calcium by platelets and a release of PF4 and adenine nucleotides in addition to that of serotonin.

This paper reports the analyses of three techniques for phase noise reduction in the complementary metal‐oxide semiconductor (CMOS) Colpitts oscillator circuit topology. Namely, the three techniques are inductive degeneration, noise filter, and optimum current density. The design of the circuit topology is carried out in 28‐nm bulk CMOS technology. The analytical expression of the oscillation frequency is derived and validated through circuit simulations. Moreover, the theoretical analyses of the three techniques are carried out and verified by means of circuit simulations within a commercial design environment. The results obtained for the inductive degeneration and noise filter show the existence of an optimum inductance for minimum phase noise. The results obtained for the optimum bias current density technique applied to a Colpitts oscillator circuit topology incorporating either inductive degeneration or noise filter show the existence of an optimum bias current density for minimum phase noise. Overall, the analyses show that the adoption of these techniques may lead to a potential phase noise reduction up to 19 dB at a 1‐MHz frequency offset for an oscillation frequency of 10 GHz. © 2015 The Authors International Journal of Circuit Theory and Applications Published by John Wiley & Sons Ltd.


This contribution investigates on the acoustics of violin, and more specifically on the relationship existing between vibrational impulse responses and the timbre of the instrument. With respect to previous publications on this topic, we tackle the problem using a feature-based approach. More specifically, we aim at finding the correlation between the features extracted from accelerometric measurements of the bridge mobility and from audio recordings of a prescribed set of performances. Results demonstrate that features describing to the global shape of the spectrum are strongly related. On these descriptors we also show the possibility of predicting the features of audio recordings from the vibrational ones. Experimental data are based on a set of 25 modern violins.


Broadband GaAs/AlxGa1−xAs quantum well infrared detectors grown by molecular beam epitaxy have been demonstrated which are sensitive over the λ=8–12 μm atmospheric window spectral region. These are the first high‐detectivity bound state to extended state quantum well detectors which are peaked at λ=10 μm. The spectral bandwidth (Δν/ν) of these devices is three times larger than our earlier λ=8 μm device. The detectivity D* is background limited at T=50 K with D*=1×1010 cm (Hz)1/2 /W, and a noise equivalent temperature change of NEΔT=0.01 K.


Optical characterization of solar concentrators is of crucial importance for main two reasons: to compare the measured values of optical features to the nominal values pertaining to the optical design; to verify the homogeneity of collector production, comparing the optical features among the different samples corresponding to the same design. Measurement configurations and standardized procedures were developed to optically characterize solar components of various shapes, dimensions and collection characteristics. This laboratory characterization involves collection efficiency assessment, image plane analysis, angle dependence studies and image size measurements. As example, the paper presents the optical characterization of prototypes of collectors designed to concentrate sunlight on photovoltaic cells.


High quality semiconducting famatinite (Cu3SbS4) nanofibers and tetradrite (Cu12Sb4S13) nanoflakes have been selectively synthesized through mild hydrothermal and solvothermal synthesis routes, respectively. The morphology and phase of the products can be successfully controlled by choosing appropriate reaction media to adjust the dynamics of the reaction process. It was found that reaction temperature is an important factor influencing the phase purity of the products. This method may provide a general route for the selective preparation of other semiconducting multinary sulfide nanocrystallites.


In this study dynamic stability problems in head seas are investigated with the use of a timedomain, non-linear numerical model of ship's motions in 5 degrees-of-freedom (sway, heave, roll, pitch, and yaw). The results presented in this paper have shown that the ship can be subjected to the wave-induced parametric resonance in regular and also in irregular waves. A quasi-static approach is adopted to determine the non-linear restoring coefficients in heave, roll, and pitch motions in waves, in which calculations are made using a pressure integration technique over the instantaneous submerged hull. Dynamic and hydrodynamic effects in waves for a given encounter frequency are included in the 5 degrees-of-freedom responses calculations, which are based on the potential flow strip theory. Comparisons between computed values and applicable experimental results demonstrated the usefulness of the technique proposed.


The Global Lung Function Initiative (GLI) all-age reference equations for carbon monoxide transfer factor were published in 2017 and endorsed by the European Respiratory Society and American Thoracic Society. In order to understand the impact of these new reference equations on the interpretation of results in children referred from haematology and oncology paediatric services, we retrospectively analysed transfer factor results from any paediatric patient referred from haematology/oncology in the period 2010–2018. We examined transfer factor of the lung for carbon monoxide (TLCO), transfer coefficient of the lung for carbon monoxide (KCO) and alveolar volume (VA) from 241 children (age range 7–18 years, 130 male). The predicted values from Rosenthal and GLI were plotted against height. The difference in interpretation of results was analysed by looking at the percentage of patients below the lower limit of normal for each parameter. Overall, the Rosenthal predicted values for TLCO were higher than those predicted by GLI. Predicted KCO using Rosenthal was higher in all observations. In contrast, the Rosenthal predicted VA was generally lower than the GLI value. The GLI predicted values for transfer factor show considerable differences compared with currently used paediatric UK reference values, differences that will have a significant impact on interpretation of results. There will be significant clinical differences in the results of transfer factor when switching to the GLI-2017 from Rosenthal-1993 reference values, strongly recommending implementing the use of GLI-2017 reference equations for paediatrics https://bit.ly/3o0zR4f


Today, new test tool ideas are emerging from existing and numerous startup EDA companies. Projected design methodologies and fabrication technologies will tend to dictate which EDA solutions are critical rather than just helpful or ?cool?. Panelists will be asked to formulate short-term (2 years) and longer term (IO years) ?wish lists? for EDA test tools and propose rationale for their choices, especially understanding the constraint of limited resources for tool R&D and purchase.


The risk factors for metabolic syndrome include central obesity, hypertension, atherogenic dyslipidaemia and insulin resistance. Metabolic syndrome affects 33% of women with polycystic ovary syndrome (PCOS) and has been less well researched than other features such as infertility, anovulation and hirsutism. Consequences of metabolic syndrome include cardiovascular disease, type II diabetes, cancer, sleep apnoea and psychological problems. Cardiometabolic risk screening involves obtaining data on smoking history, weight, body mass index, waist circumference, blood pressure, lipid profile, and taking an oral glucose tolerance test. Management of metabolic syndrome should focus on risk factors and individual components. Lifestyle modification is the only recommended intervention at present.

In this article, Ohigashi et al. developed a new unique nomogram to predict the probability of the existence of insignificant prostate cancer (PCA) before biopsy. The authors analyzed predictors of insignificant PCA using prebiopsy data from a total of 620 patients with serum total prostate-specific antigen (PSA) of less than 10 ng/mL and radical prostatectomy (RRP) specimen findings from 129 patients who were confirmed to have histological PCA and then subsequently underwent RRP. Of the 129 patients, 22 had insignificant PCA and digital rectal examination (DRE), PSA adjusted for transition zone volume (PSAD-TZ) and free to total PSA ratio (F/T) were the independent predictors of significant cancer in multivariate analysis. Based on these predictors, this new nomogram was made. To date, there are a few reports in which PSA doubling time (PSADT) and PSA velocity (PSAV) are predictors of insignificant PCA detection. Therefore, it would be interesting to see if the addition of PSADT and PSAV as predictors of insignificant PCA detection would improve the quality of this nomogram. Needless to say, it is most important for urologists to utilize the nomograms in clinical practice, but making the nomograms isn't a goal. If the nomograms aren't useful in clinical practice, there isn't a need for them. As the authors noted, this study had several important limitations, which were small sample size, and lack of standardized biopsy strategy and numbers. Therefore, at the present time it might be impossible to utilize this nomogram in its present form in clinical practice. Also, it is currently not easy to predict insignificant PCA before surgery. Moreover, because the burden of biopsy for patients has recently reduced because of improvements in biopsy methods and anesthesia, it might now be appropriate to use nomograms that include biopsy data in clinical practice. Accordingly, this nomogram is currently considered to be in its early stages; however, if the use of this nomogram is proven by external validation, this nomogram will be one of the most useful nomograms in clinical practice. I hope a large external validation is carried out in the near future.

Abstract Preliminary results of the effect of hydrophobicity and halogenation on the cytotoxicity of the anticancer peptaibol culicinin D are reported. Building on previous work, the synthetically challenging (2S,4S,6R)-2-amino-6-hydroxy-4-methyl-8-oxodecanoic acid and (2S,4R)-2-amino-4-methyldecanoic acid building blocks were replaced with derivatives of l-phenylalanine and 2-aminodecanoic acid, respectively. Substitution of (2S,4S,6R)-2-amino-6-hydroxy-4-methyl-8-oxodecanoic acid with l-4,4′-biphenylalanine yielded an analogue that was tenfold more potent than the natural product and was also the most hydrophobic analogue, as judged by an antiproliferative IC50 assay and logD calculations; these results suggest that the potency of culicinin D may be governed by its hydrophobicity. However, the introduction of halogenated moieties into the peptide sequence generated analogues that were similarly potent, although not necessarily hydrophobic. Thus, the parameters regulating the cytotoxicity of culicinin D, and by extension other peptaibols, are multimodal and include both halogenation and hydrophobicity.


Amorphous calcium phosphate (ACP) coatings were formed on magnesium substrates via a straightforward electrochemical technique in order to improve the corrosion resistance of the substrates. X-ray diffraction spectroscopy and microscopy techniques were used to investigate the size, morphology, composition and structure of the ACP coatings. Analysis of the ACP coatings revealed the presence of micrometre scale fissures and tubular structures. Despite the presence of these features, the coatings were still capable of significantly reducing the corrosion rate in both PBS and Ringer's solutions. Ringer's solution was found to be the most aggressive towards Mg substrates with a corrosion rate of 3.828 mm/yr. However, after electrochemical treatment, the corrosion rate of substrates coated with ACP was reduced to 0.557 mm/yr. The significant improvement in corrosion resistance is a first step in controlling the corrosion rate of biodegradable Mg substrates for potential use in hard tissue applications.

This paper aims to research the elements that affect the decision to implement Artificial Intelligence (AI) in supply chain management at SMEs in Da Nang, Vietnam. The application of new technologies in supply chain management is significant during the development period of industry 4.0. A more in-depth examination of the issues in implementing AI in the supply chain will provide a more objective perspective on the challenges and benefits of adopting AI to supply chain management in SMEs. This paper investigates the effect factors in implementing Artificial Intelligence (AI) technology by constructing a Technology-Organization-Environment (TOE) framework. To achieve the research objectives, this study used two approaches. First, a qualitative approach is used to build a research hypothesis framework. Second, the quantitative approach includes explanatory factor analysis, Pearson Correlation, and regression methods by utilizing survey data on 120 MSMEs in Da Nang. The results indicated that the complexity, compatibility, cost, and external pressure factors are not essential in AI implementation. Referring to those technical factors (relative advantages), organization factors (top management support, organization readiness), and environmental factors (government support) have a positive influence on the technology implementation of AI in supply chain management.


The cross sections for vibrational and rotational excitation of H2, Li2, Na2 and K2 by slow electrons are calculated in the adiabatic approximation using a zero range potential model to obtain the amplitude of electron scattering for a 'frozen' molecule. The advantage of the zero range potential model is the possibility of taking into account explicitly the effect of multiple scattering. The results are compared with the available experimental data and other calculations.

The race is on to find an alternative to warfarin, which is currently the most effective agent for preventing stroke in patients with atrial


Haze can cause significant changes in the data domain of the image. Due to domain-shift problem, the model trained on the synthetic haze images has a weak or even invalid dehazing ef-fect on the real data. This paper proposes an unsupervised domain adaptation dehazing method based on the nearest-farthest subspace distance in response to this problem. For the middle convolved features, the matrix singular value de-composition is used to obtain the basis vectors of the support subspace. Narrowing the angle between the basis vectors of natural and synthetic haze domains could reduce the differ-ence between the data domains. In subspace, a newly defined distance with a new penalty term named subspace measure distance is employed to constrain the model. Furthermore, to avoid search blindness of the proposed method in the real data training phase, we propose the nearest-farthest subspace distance inspired by contrastive learning. In addition, we use a new training strategy. Finally, the experimental tests on the synthetic and real images prove the effectiveness of the pro-posed method.


Acute toxicity of linear alkylebenzene sulfonate (LAS) on juveniles of Metapenaeus monoceros was evaluated by static bioassay. The LC sub(50) values ranged between 8.61 and 5.10 ppm for 24 to 120 hours


Introduction: Numerous studies have shown the association between outdoor air pollution and mortality, as well as hospital admissions and emergency visits for respiratory illness such as COPD, asthma and pneumonia and also cardiovascular diseases such as stroke, ischemic heart disease and angina/myocardial infarction. In western countries, this relationship has been established a while back. However, South-East Asian countries require more studies in order to explore the effects of ambient air pollutants on its population health. Method: This study was conducted to determine the associations and risk estimates of daily variations of air pollutants in the Bandar Tun Razak area with cardiovascular and respiratory cases from both hospital admissions and emergency room visits at Hospital Cansellor Tuanku Muhriz UKM (HCTM). Data on daily hospital admissions for HCTM (2010-2014), were obtained from Jabatan Maklumat Kesihatan , HCTM and emergency room visits for HCTM (2013) were obtained from the Center of Research for Emergency Medicine (CREM), HCTM. Daily mean concentrations of air pollutants of particulate matter less than 10ug/m 3 (PM 10 ), sulfur dioxide (SO 2 ), carbon monoxide (CO), nitrogen dioxide (NO 2 ), ozone (O 3 ), and daily observations of meteorological conditions were obtained from Malaysian Department of Environment. We examined the associations between daily level pollutants and daily hospital admissions and emergency room visits of cardiovascular and respiratory using time series analysis of Poisson regression while controlling for time trends, meteorological factors and holiday indicator. Effects for every 10ug/m 3 increase in pollutants were reported as Relative Risk  (RR) on current-day (lag 0) exposure to previous five days (lag 5). Results: The highest association among all was from respiratory admission with SO 2 at lag 4 (RR = 1.123113, 95% CI = 1.045253-1.206772), followed by cardiovascular admission with NO 2 at lag 5 (RR = 1.025222, 95% CI = 1.004689-1.046174), NO 2 at lag 0 (RR = 1.022244, 95% CI = 1.000757-1.044192) and O 3 8hour at immediate effect lag 0 (RR = 1.020816, 95% CI = 1.006672-1.035159). The highest association with respiratory emergency was with PM 10 at lag 0 (RR = 1.012778, 95% CI = 1.003016-1.022635) while cardiovascular emergency recorded the highest with CO at lag 1 (RR = 0.997912, 95% CI = 0.996051-0.999776). Conclusion: Significant associations were found with all cardiovascular and respiratory admissions in the single-pollutant model for all the pollutants. Gaseous pollutants showed higher risk in both cardiovascular and respiratory admissions while PM 10 showed higher risk in respiratory emergency. Both immediate and delay effects were also found in both hospital admissions and emergency visits for cardiovascular and respiratory diseases associated with all polutants.


From January 1989 to April 1996 15568 individuals (5057 inpatients 3466 outpatients 5438 women attending the antenatal clinic and 1607 secondary students) were screened for HIV-1 virus at St. Marys Lacor Hospital northern Ugandas main hospital. For inpatients estimated prevalence rates with exact binomial 95% confidence intervals were 57.9 (53.3-62.4) for 1989 52.1 (49.0-55.1) for 1990 51.9 (48.1-55.6) for 1991 64.2 (60.2-68.2) for 1992 56.0 (51.7-60.1) for 1993 65.4 (62.3-68.5) for 1994 57.2 (52.6-61.8) for 1995 and 56.1 (50.0-62.1) for 1996. For outpatients they were 44.5 (38.8-50.2) for 1989 53.3 (49.6-56.9) for 1990 60.1 (51.6-8.2) for 1991 64.1 (55.3-72.3) for 1992 45.8 (39.1-52.7) for 1993 44.1 (40.1-47.6) for 1994 39.3 (36.0-42.8) for 1995 and 43.7 (38.0-49.6) for 1996. For pregnant women they were 27.1 (24.4-30.0) for 1993 21.9 (20.2-23.8) for 1994 14.7 (13.1-16.4) for 1995 and 11.7 (8.8-15.1) for 1996. For secondary school students they were 2.0 (1.1-3.3) for 1994 1.4 (0.7-2.5) for 1995 and 1.8 (0.4-5.1) for 1996. Adjusted odds ratios (ORs) were calculated using a logistic regression model that controlled for gender group and year tested. Logistic regression models were also used to test for each group the presence of a significant linear change over time in risk of being infected controlling for gender. The adjusted OR per group with a 95% confidence interval for inpatients was 79.1 (53.6-116.6); for outpatients it was 68.4 (46.3-101.1); for pregnant women it was 14.3 (9.7-21.1); and for secondary school students it was 1.0. 48.4 % of students were not yet sexually active. The adjusted OR with a 95% confidence interval/year tested was 1.1 (0.9-.4) for 1989 1.1 (1.0-1.4) for 1990 1.1 (0.9-1.4) for 1991 1.8 (1.5-2.2) for 1992 1.6 (1.3-1.9) for 1993 1.7 (1.4-2.0) for 1994 1.0 (0.9-1.2) for 1995 and 1.0 for 1996. A significant decrease was found for pregnant women (OR = 0.69; p < .001). Stable or decreasing HIV-1 seroprevalence over time does not necessarily imply decreasing incidence; increasing mortality and migration among HIV-1 infected persons can obscure increasing incidence. The data indicate a homogeneity in the epidemic throughout Uganda.

The High Efficiency and Resolution Canterbury University Large Echelle Spectrograph (HERCULES) is a fibre-fed echelle spectrograph that has been in operation at the Mount John University Observatory for just over one year. HERCULES is used in conjunction with the 1-m McLellan telescope, and can capture the spectrum from 380 nm to 880 nm on a single 50-mm square CCD. Resolving powers of up to 70000 are possible when using 50-μm fibres, and a resolving power of 35000 is possible with a 100-μm fibre. Wavelength calibration is done using sequential exposures of a thorium-argon emission lamp. The spectrograph is designed to achieve high efficiency when the seeing is well matched to the image scale on the fibre input (up to 20% in 1 arcsec seeing), and high stability is achieved by having the spectrograph installed inside a vacuum tank in a thermally isolated environment. Initial indications are that radial velocities with a precision of ≤ 10 ms-1 are routinely possible in the short-term.


This chapter draws on my own experience as a policy-engaged researcher to illustrate how management research can be used to infl uence policymakers. The discussion then expands to consider the relevance for management researchers of current developments in wider academia, notably the emphasis on 'relevance', 'economic impact' and 'knowledge transfer'. The structure is as follows. The following section describes my own experiences and the subsequent section refl ects upon the lessons that might be drawn. The fourth section considers how policy-engaged management researchers might choose a profi le of engagement that benefi ts their academic work as well as contributing positively to public policy. The fi fth section examines current developments, including the pressures for evidence of 'relevance' and 'economic impact', in relation to both grant funding and research assessment.


An experiment has been devised to evaluate the electric Nusselt number in a suspension of spherical hematite particles (hematite in distilled water). The experiment was conducted using a single platinum wire (diameter=0.025 mm) mounted along the axis of a copper cylinder (diameter=53 mm). The Nusselt number was evaluated for various experimental parameters such as time, electric field, frequency, orientation, charge and concentration of the colloidal particles. An increase in Nusselt number was observed in an ac field, and the increase was extremely sharp for pH values largely different from the isoelectric point (i.e.p.). A similar effect was also noted in a dc field at a very weak field strength. An increase in concentration of the colloidal particles increased the Nusselt number and a similar effect was also noted when the cylinder was moved from the horizontal to the vertical position. An attempt was made to evaluate the efficiency of convection using an empirical relationship and the results for ac and dc fields are presented.


In this paper, we propose a new technique for converting gray level images into bi-level images, while the most significant information in original gray level image are preserved. From experimental, the reconstructed quality is better than Otsu and Kapur's methods. The well-known digital halftoning is traditionally applied to get a high quality binary image for specified output devices, e.g., printers. However, the halftone image is not suitable for some image processing, such as downsampling or further compression. These problems can be solved with the proposed 3-step bi-leveling, which including Sobel high active regions detection, LMS-designed halftoning, local and global smooth region binarization


Excessive nitrate in the water impose a danger to human health and contribute to eutrophication. The present continuous fixed bed pilot study was carried out using granular activated carbon made from walnut shell for removal of nitrate from aqueous solution and natural groundwater. The carbon was characterized using SEM, FTIR and BET. The BET specific surface area and average pore size before nitrate adsorption were 1434.6 m 2 g −1 and 2.08 nm, respectively, and after were 633.28 m 2 g −1 and 2.04 nm, respectively. Optimum removal of nitrate was achieved at a contact time of 2 min, pH of 6.5 and a nitrate concentration of 200 mg/l. The hydraulic loading rate was calculated to be 10 m 3 /h.m 2 and the maximum adsorption capacity using the Langmuir adsorption isotherm model (R 2 = 0.99) was 10 mg NO 3 /g. These experiments were also carried out using groundwater and the removal of nitrate decreased from 68% to 60% because of competition with other cations and anions.


The Arctic region, on one hand, an area situated so far from the European Union and, on the other hand, an environment so hostile to life, is în the spotlight of the world's powers. The resources, so necessary for the nations, ‒ the riches în the depths of the soil and în the ocean ‒, the potential of tourism and the importance of shorter transport routes aroused the interest of some actors în the region. The European Union has developed a policy for the Arctic region. Are the European Union՚s concerns strictly related to security and the economy or is there a much wider horizon of goals to be achieved?

Keywords: The Arctic region; European Union; globalization; climate change; threat; international security.


An experimental performance test has been carried out to improve a new blade with higher performance. Most of blades of the fan are designed to be a seamless and simple type, and the flow momentum can generally be evaluated to be comparatively low. Because some portions of the blowing winds can easily be passed through the seamless sharp edge of the blade, and several results studied on these problems have been reported: on the simple blade with edge-line seam, on the simple blade with guide seam. However the results do not show the remarkable increasement of performance of the blades. In this experimental performance test of the blades the design techniques of the blades with double seams (stem seam and edge seam) and comparison tests have been focused. As a first step the comparisons of velocity distributions and flow-rates depending upon the blade are presented in this paper.


In an attempt toward the synthesis of 20 (S)-protopanaxadiol (I) from dammarenediol-II (V), the introduction of a hydroxy function to C-12 of the dammarane skeletone has been studied. A solution of p-nitrobenzoate (IX) of 3-epi-dammaranediol-I (VIII) in tert-BuOH was irradiated for 40 hr and the products were saponified to give 17-octakis-nordammarane-3α, 17β-diol (X). From the crude irradiation products, 6-methyl-2-heptanone (XII) was isolated and identifiel. Whereas, the irradiation of p-nitrophenylacetate (XIX) of 3-epi-dammaranediol-II (XVI) under the similar condition followed by saponification yielded the 12-hydroxy compound (XX). This was converted into betulafolienetriol (XXI) and 20 (S)-protopanaxadiol (I) furnishing the synthesis of the Ginseng sapogenin.


We study zero-cycles in families of rationally connected varieties. We show that for a smooth projective scheme over a henselian discrete valuation ring the restriction of relative zero cycles to the special fiber induces an isomorphism on Chow groups if the special fiber is separably rationally connected. We further extend this result to certain higher Chow groups and develop conjectures in the non-smooth case. Our main results generalise a result of Koll\'ar [28].


Process under development supplies oxygen for life support in hazardous environments. Prototype CO2 reactor vessel produces oxygen from carbon dioxide at expense of about 100 watt-hours of electricity per liter of gas reduced. Design changes to improve efficiency include narrowing gap between walls to operate at lower voltages and increasing area of one electrode while decreasing area of other to reduce capacitance.


During the summer of 1949, the writer collected 500 numbers of plants from the island of Ponape, the laegest of the eastern Caroline Islands. Approximately 75 of these were non-vascular plants. The vascular flora of Ponape has already been treated in a recent paper by the writer (1952). The present work, however, appears to be the first attempt to list all available records of non-vascular plants occurring on the island.


The Departments of Dermatology and Syphilis and of Pathology of the Western Reserve University and of the Lakeside Hospital. To the Editor: —For several years I have collected book plates, more particularly plates owned by physicians, also the book plates of medical libraries, medical schools, hospitals, etc., and it has been suggested to me that a check list of these ex libris would be of interest. I cannot flatter myself that I possess specimens of all book plates owned by physicians, by medical libraries, etc., in the United States, and therefore take the liberty of asking, through the columns of The Journal, that physicians who own such marks of ownership for their books favor me with specimens, also informing me of the names of artists (designers, etchers and engravers).
