Indoor localization systems based on Visible Light Communication (VLC) have shown promising advantages compared with systems based on other wireless technologies. In these systems, many VLC light-emitting diode (LED) anchors are employed in an indoor space in which location identification messages are sent to user devices in short messages. In normal beacon VLC networks, micro-controller (MCU) or low-end system-on-chip (SoC) are often the processing hub which executes messages of many VLC access points. In this paper, we discuss the processing overload and implementation cost of the two typical models of VLC beacon network in scenarios of a hundred of VLC-LED anchors are taken into account. Finally, an FPGA-based centralized VLC transmitter and its aided Nios II-based system has been introduced to enhance the performance of the VLC beacon network. Besides, due to the centralized processing, our system model is considered to be more cost-efficient than the dedicated-processor-based models.


Thyrotropin releasing hormone (TRH) was given to 6 women for 8 consecutive days beginning between Days 8 and 9 of the menstrual cycle. Daily serum samples were obtained for radioimmunoassay for lutcinizing hormone (LH), follicle-stimulating hormone (FSH), and prolaclin (PRL) secretory response. Thyrotropin releasing hormone was ineffective in interfering with ovulation and failed to show significant effects on cycle lengths. Moreover, the length of the lutcal phase was not affected by TRH, as demonstrated by basal body temperature, endometrial biopsy, and pregnancdiol excretion. These results are in disagreement with recent findings in baboons receiving TRH. This study also demonstrated that TRH administration induces a prolactin secretory response which blocks neither the LH surge nor the ovarian responsiveness to endogenous gonadotropins women who menstruate normally.

Humanization of health care provision is a vibrant topic in academic and public discussions. Sweden pioneered innovative educational policies seeking to forge commitment among a new generation of doctors to a "patient-centred" approach. In accordance with Michel Foucault's theoretical elaborations, this study takes the discourse of humanization to be a feature of politico-economic regulation or governing, and measures the adherence of doctors to this humanization project. Our survey, conducted during autumn 2013-spring 2014, involved 116 doctors affiliated at middle and large-sized public institutions providing primary care and specialized dermatological clinics in western and southern Sweden. A questionnaire comprised of 24 questions that tested the relationships between doctors' embeddedness in the professional culture and their approaches to non-clinical aspects of dermatological illnesses. The obtained data was processed with the help of the SPSS-21 statistical program, using descriptive and Chi-test statistics. Semi-open questions and respondents' spontaneous reactions were analyzed by identifying categories of meanings or themes and their frequency. All doctors involved in the study demonstrated recognition of the psychosocial impact of dermatological disorders, and a vast majority agreed on the need to account for non-clinical aspects of skin illnesses in clinical practice. Technical level of specialization manifested itself as the strongest factor shaping doctors' sensitivity to the psychosocial difficulties of dermatological disorders, related attitudes and practices. A significant number of the physicians reported self-reflectivity and expressed a desire for further education about social-psychological management in dermatology. These attitudes are consistent with the humanization imperative that frames general professional training. An inquiring-supporting conversation with a patient, which can be seen as a form of empowering or enabling sociality, was revealed to be the central format used by the doctors in addressing the non-clinical aspects of skin disorders. Simultaneously, the principle of efficiency surfaced in participants' open-ended responses, a factor that could potentially destabilize the humanization effect. Medical professionals become middle-range agents of governing that is grounded in the complex structure of contradictory discourses. This study demonstrates the success of the humanization process in medical education and practices, and underlines the need to foster a critical approach to professionalism capable of addressing the paradoxes in the humanization of the healthcare in Sweden.


Without question, Giorgio Vasan s Lives of the Artists (Florence: 1568) is the single most important source for humorous anecdotes and stories about Renaissance artists. Still, such tales existed long before the first appearance ofVasari's book. For example, Giovanni Boc caccio's Decameron (c. 1350) contains a fa mous story about Giotto and several more about the fun-loving trickster and artist Buon amico Buffalmacco and his companions Bruno and the simpleton Calandrino.1 Among trecento authors of stories about artists, Franco Sacchetti is second in impor tance only to Boccaccio. His Trecentonovelle (c. 1395) contains two tales about Giotto, sev eral more about Buffalmacco, and a few other far-less-well-known stories.2 Among the no velle that have been largely overlooked is one (170) about a messer Pino Brunelleschi and "a painter of rooms" named Bartolo Gioggi, who, Sacchetti says, was no less singular a person than Buffalmacco.3 As Sacchetti s story goes, Pino asks Bartolo to paint a room in his palace and to depict numerous birds ("molti uccelli") among the trees in the upper part of the fresco. Pino then goes into the countryside for a month, during which time Bartolo almost completes the painting. On Pino's return, as he and Bartolo examine the room, the artist asks for payment. Having carefully scrutinized the artist's work, Pino responds, "Bartolo, you have not served me well, nor as I instructed you, for you have not painted as many birds as I wanted." To which Bartolo immediately says, "Sir, I painted many more than you see here, but your servant left the windows open, and a great many of the birds flew away." Pino, knowing Bartolo to be a great drinker, replies, "I firmly believe that my servant held open the door of the wine cellar and has given you drink to such an extent that you have ill served me, and you will not be paid as you expect." When asked why he had not painted more birds, Bartolo jokingly answers that some of his representations of birds, seeing an opportunity to escape, flew away out open windows. Bartolo's reply may be under stood as a travesty of Boccaccio's descrip tion in the Decameron (6.5) of Giotto's ability to create overwhelmingly lifelike representations of nature. According to Boc caccio, Giotto was so gifted an artist that his depictions looked not like the imitation of a thing, but like the thing itself. His paintings often so deceived viewers that they believed they were looking at the natural object and not at Giotto's representation of it. In effect, Bartolo tries to convince Pino that his painted birds are as lifelike as Giotto's depicted objects seem to be. Reading Sacchetti's tale from another perspective, we might say that Bartolo tries to convince Pino that he is like the mythical Pygmalion, who, with the help of Venus, transforms a figure of a woman carved in ivory into a living person. In other words, just as Pygmalion transforms ivory into


10003 Background: Second malignant neoplasms (SMN) are a known complication of Hodgkin disease (HD) treatment. While it is theorized that lower radiation doses may be associated with lower SMN risk, long-term follow-up of children treated with low-dose radiation is lacking. We report the occurrence of SMN among pediatric HD survivors treated at Stanford with chemotherapy and low-dose radiation from 1970 to 1990.

METHODS
Patients received 6 cycles of MOPP (mechlorethamine, vincristine, prednisone, procarbazine) with 15-25.5 Gy radiation ± 10 Gy boost or 3 MOPP and 3 ABVD cycles (doxorubicin, bleomycin, vinblastine, dacarbazine) with 15 Gy radiation ± 10 Gy boost. Follow-up was obtained through 9/1/2007. Standardized incidence ratios (SIRs) and absolute excess risk (AER) for SMN were calculated using the SEER9 database (1973-2004). Cumulative SMN incidence was determined by the Kaplan-Meier method. Univariate associations were evaluated with the chi-square test or t-test. Multivariate analysis was performed with Cox proportional hazards regression using chronological age as the time scale.

RESULTS
One hundred ten of 112 patients achieved remission; median follow-up is 20.6 years. Four patients developed secondary leukemia. Fifteen patients developed 17 secondary solid tumors (5 thyroid carcinomas, 6 breast carcinomas, 4 sarcomas, 1 bladder paraganglioma, 1 melanoma) at a median of 15.4 years. All solid tumors except the melanoma occurred within or at the margin of radiation fields, ranging in dose from 15-26.5 Gy. There were no cases of lung, gastric, or colorectal carcinoma. Cumulative incidence of any SMN is 17% (95%CI 10.5-26.7) at 20 years following HD diagnosis. The SIR for any SMN is 22.9 (95%CI 14.2-35) with an AER of 93.7 cases per 10,000 person-years. In univariate analysis, older age at HD diagnosis (>11 years) and female gender were associated with SMN (p<0.05). In multivariate analysis, there were no statistically significant associations.

CONCLUSIONS
The incidence of SMN in pediatric HD survivors is elevated following treatment with chemotherapy and low-dose radiation. Sarcomas, breast, and thyroid carcinomas occurred with similar frequency and latency as found in studies of HD survivors who received high-dose radiation. No significant financial relationships to disclose.

A new approach for selecting the weighting matrices of Hinfin mixed sensitivity and robustness problem in an active magnetic bearing (AMB) system is presented. First an extended dynamic model of a magnetic bearing is developed in state space form. Then, two separate controllers are designed to solve the problem of imbalance in an AMB system. One controller is used to compensate the imbalance forces by generating electromagnetic forces on the bearing surface to cancel these sinusoidal forces (imbalance compensation). Another controller is used to prevent the generation of imbalance forces by forcing the rotor to rotate around its axis of inertia. Simulation results are presented to compare the performance of the designed controllers with a typical general purpose Hinfin controller.

ITKIN (1956, 1958) has cited considerable evidence which indicates that, win bacteria, ultraviolet light (UV) induced mutation is irreversibly established only after an appreciable delay. Her studies suggest that the induction process is completed during the period prior to the first postirradiation cell division and is dependent on the availability of amino acids. WITKIN suggested that protein synthesis is involved in mutation induction since she found that chloramphenicol (Chl) , an antibiotic which blocks protein synthesis, appreciably lowers the mutation frequency obtained with a given dose of UV. basis for UV-induced mutation nucleic acid precursors altered in uiuo that ribonucleic acid (RNA) synthesis, as well as protein synthesis, is involved in the mutation induction process. results to the suggestion that RNA and protein are involved in replication of deoxyribonucleic acid (DNA). As one possibility it was suggested that the RNA is modified through incorporation of the UV-altered purine or pyrimidine and that this modification in RNA specificity leads to a change in the genetic specificity of the DNA subsequently formed.

Stereo vision is used in many application areas, such as robot-assisted manufacturing processes. Recently, many different efficient stereo matching algorithms based on deep learning have been developed to solve the limitations of traditional correspondence point analysis, among others. The challenges include texture-poor objects or non-cooperative objects. One of these end-to-end learning algorithms is the Adaptive Aggregation Network (AANet/AANet+), which is divided into five steps: feature extraction, cost volume construction, cost aggregation, disparity computation and disparity refinement. By combining different components, it is easy to create an individual stereo matching model. Our goal is to develop efficient learning methods for robot-assisted manufacturing processes for cross-domain data streams. The aim is to improve recognition tasks and process optimisation. To achieve this, we have investigated the AANet+ in terms of usability and efficiency on our own test-dataset with different measurement setups (passive stereo system). Input of the AANet+ are rectified stereo pairs of the test-dataset and a pre-trained model. Instead of generating our own training dataset, we used two pre-trained models based on the KITTI-2015 and SceneFlow datasets. Our research has shown that the pretrained model based on the Scene Flow dataset predicts disparities with better object delimination. Due to the Out-of-Distribution inputs, only reliable disparity predictions of the AANet are possible for test data sets with parallel measurement setup. We compared the results with two traditional stereo matching algorithms (SemiGlobal block matching and DAISY). Compared to the traditionally computed disparity maps, the AANet+ is able to robustly detect texture-poor objects and optically non-cooperative objects.


Analysis is given for nonstationary propagation of rotating ion beam which has a finite length on the basis of Vlasov–Maxwell equations. The beam velocity distribution function is assumed to have a form of product of a modification function g which depends on time and axial coordinate multiplied by a steady solution f b 0 which is a known function of particle velocity and radial coordinate. Unknown function g is solved as the solution of Vlasov equation through electromagnetic fields induced by leading and trailing edges. These electromagnetic fields can be solved from the Maxwell equations by using beam distribution function and motion of electrons in background plasma.


It is well-established that α-synuclein aggregation may proceed through an initial lipid-dependent aggregate formation and, if at acidic pH, a subsequent aggregate-dependent proliferation. It has also been recently reported that the aggregation of α-synuclein may also take place through an alternative pathway, which takes place within dense liquid condensates produced through liquid-liquid phase separation. The microscopic mechanism of this process, however, remains to be clarified. Here, we developed a fluorescence-based assay to perform a kinetic analysis of the aggregation process of α-synuclein within liquid condensates, and applied it to determine the corresponding mechanism of aggregation. Our analysis shows that at pH 7.4 the aggregation process of α-synuclein within dense condensates starts with spontaneous primary nucleation followed by rapid aggregate-dependent proliferation. Taken together, these results reveal a highly efficient pathway for the appearance and proliferation of α-synuclein aggregates at physiological pH.


Editor's Note: When the Sadler's Wells Ballet embarked on a good-will tour of Holland, Belgium, and France on May 4, 1940, nine months after the outbreak of World War II, the so-called "phony war" was nearing its end. A month earlier German forces had over-run Denmark and landed in Norway. On May 10, German forces crossed the Dutch, Belgian, and Luxembourg borders, poised to overrun France from north of the Maginot Line. On May 14, the Dutch government fled to England, German bombers devastated Rotterdam, and the commander of the Dutch forces surrendered to avoid annihilation. By May 10 the Sadler's Wells company had performed once in The Hague, where they were staying, and three times in towns near the German border, at Henglo, Eindhoven, and Arnhem. On the evening of the eleventh they were taken to a temporary refuge in the countryside near Velsen and on the thirteenth boarded a ship at Ijmuiden, arriving safely at Harwich early the following afternoon. Left behind in their flight were the sets, costumes, and music for the ballets they had been touring: The Rake's Progress, The Wise Virgins, Checkmate, Dante Sonata, Fa9ade, Les Patineurs, and Horoscope. Most of these were restored to the repertoire, but the full score of Horoscope has never been reconstructed from Lambert's manuscript and the ballet has not been performed since then. The basic story of the company's narrow escape has been


Significance Floods impact food security for ∼12% of our modeled African population that experienced food insecurity during our study period. Flood impacts on food security vary depending on scale, with declines likely at smaller scales but mixed impacts at national and regional scales. Improved data collection at the intersection of flooding and food security, and at the spatial scales ranging beyond conventional humanitarian responses, is critical to better mitigate food security impacts of flood disasters across Africa and globally.


In the present chapter, we summarize our results concerning fractal analysis of some medical data. The aim of this study is to identify the inherent human body " chaotic " dynamics and insufficient disclosure of the physical essence of the processes observed, depending on the extent of developing a pathology that is characterized by a decrease or increase in the degree of complexity and as a consequence — randomness, for which, in some cases, hidden fractal. The proposed approach based on identifying the presence of the properties of self-similarity can be useful in preliminary clinical trials for the diag- nosis of cancerous epithelial diseases, blood, and liver in the initial stage, the analysis of digital images, the structure of correlations biomedical parameters, as well as in the study of pathologies of the central nervous system — the neurological, neurodegenerative disorders, psychiatric disorders, and may be the basis for the development of the interface " brain-computer " , on the basis of electroencephalography and magnetoencephalography. Additional measures are proposed to study the presence of self-similar properties in the form of self-similarity and magnitude SRGB ratio (area of a triangle in the coordinate system of the properties).

When one repeats a physical hand movement the localization of the excitation region of the cerebral cortex is observed in the hemisphere. It was that a clear decrease of the fractal dimension value during " back " movement of the hand, and it may indicate the inclusion of a " braking " effect. During the long-term random motion of the leg (right, a steady activity excitation of parietal brain and temporal regions, with a characteristic increase of the fractal dimension of the EEG signals from the frontal region and the decrease in the occipital, is observed. It gives some evidence on the localization of activity excitation of the cerebral cortex during this kind of movement. changes in the early stages of the disease, characterized by changing the fractal characteristics (fractal dimension, SRBG method, the self-similarity ratio). In the development of applications of nonlinear dynamics in human physiology and disease noninvasive diagnostic techniques, based on the application of fractal geometry, new approaches study demonstrating the need for and benefits of fractal analysis in medical diagnostics. It is expected that the results can be the basis of new methods of medical diagnosis and treatment of diseases of the human physiological functions.

A binary space partition tree is a data structure for the representation of a set of objects in space. It found an increasing number of applications over the last decades. In recent years, intensifying research focused on its combinatorial properties, which affect directly the efficiency of applications. Important advances were made on binary space partitions for disjoint line segments in the plane and for axis-aligned objects in higher dimensions. New research directions were also initiated on some realistic polygonal scenes and on kinetic binary space partitions. This paper attempts to give an overview of these results and reiterates some of the most pressing open problems.


Aim:  The clinical significance of the urinary white blood cell (U‐WBC) count and serum C‐reactive protein (CRP) level was evaluated in an effort to improve the efficiency of prostate biopsies.


Attitudinal racism is the centerpiece of journalist Dilip Hiro's descriptive account of British race relations. Favorably citing Gunnar Myrdal's well-known assertion that "it is the popular beliefs, and they alone, which enter directly into the causal mechanism of interracial relations" (p. 291), Hiro takes as his organizing theme "the contradictions between the moral attitudes of most British and their socio-historical attitudes" (p. xxii). This orientation allows him to do a number of things very well. Without seeking to break new scholarly ground, the book summarizes the history of Empire, and the racist ideology it engendered. This ideology, Hiro effectively argues, has developed an autonomy and persistence of its own. White British of all classes have imbibed the racist drink; as a result, racist views and practices are not isolated but pervasive in British society. Hiro's focus on white attitudes is complemented by the best sections of the book which introduce us to everyday life of blacks in Britain, and indicate precisely how the attitudinal contradictions in white society get played out in the lives of black Englishmen. These discussions of West Indian-and especially Asian-cultural, economic, and political life resonate with intimate sensibility. We come to touch the pain of the immigrant ordeal and the palpable joys of communal resistance. And especially in these sections the telling is made


The role of murine rodent and insectivore as a pathogenic agent of leptospirosis carrier in pripiyat Polessye region and adjacent territories was researched. The dominant leptospirosis serogroups among wild and synanthropic rodent are pomona, icterohaemorrhagiae, grippotyphosa. Leptospirosis ahtibodies are more often detected among apodemus flavicollis, clethrionomys glareolus, microtus oeconomus, microtus arvalis, apodemus sylvaticus, sorex araneus.


Correlation and path co-efficient analysis were carried out for pod yield and its component
characters in 50 genotypes of groundnut. The genotypic correlation co-efficients were found to be of
relatively higher magnitude than the corresponding phenotypic correlation co-efficients, indicating strong
inherent association between the characters. Pod yield displayed significant positive association with kernel
yield per plant, mature pods per plant, total pods per plant, harvest index, 100-seed weight, root weight, plant
height and shoot weight. Path co-efficient analysis revealed high direct effects of kernel yield per plant and
harvest index on pod yield. Hence, it would be rewarding to give due importance on the selection of these
characters for rapid improvement in pod yield of groundnut.
Key words: Character Association, Path Analysis, Groundnut.


INTRODUCTION. This study analyses the impact of school hours on families with children in primary school and how often they use the different services and programmes offered by their schools (before-school care, after-school activities, etc.) according to their usual place of residence. Schools and how they organise their hours are considered key factors in school-family life balance. METHOD. The sample was selected by means of simple random sampling, taking into account the schools in each Galician province, their funding (state or private schools), their geographic context (rural or urban areas, in terms of high/intermediate/low population density) and the school year (years 1 to 6 in Primary Education). 3,400 questionnaires were given out and 2,037 of those collected were valid; therefore, the representativeness of the sample was highly guaranteed (error= 2.2%; confidence= 95.5%). RESULTS. The results show that school hours, after-school services and holidays are associated with families' level of school-life balance . The association between, on the one hand, the level of school-family life balance and, on the other, the existence of services at the school and its geographic context has been detected. The different services offered by schools are more commonly used by families living in cities in order to organise their time more easily. DISCUSSION. This study reveals that school life has a direct impact on how families with children in Primary Education plan their everyday lives, and it shows the differences between urban and rural areas. There is a need to develop strategic actions which will reconcile the routines of children and their families so that they can be more synchronised; and this is the task for society


In this study, an evaluation form for concentrative movement therapy (CMT; in German: Konzentrative Bewegungstherapie, KBT), an approach of psychodynamic body psychotherapy, is presented. This form has two functions: firstly, it is used for the everyday documentation of CMT and secondly, it provides data for quality monitoring. The primary intention is to assess the quality of the treatment course and result for the individual patient, rather than to study the effectiveness of a therapeutic method in general. In this study, it is discussed how this evaluation form meets the requirements of a quality assurance and quality monitoring tool for CMT. The specific therapy goals of CMT are listed because they play an important role in the documentation of CMT. In a pilot study, the treatment goals and results in the CMT group treatment were multicentrically documented with the CMT form and were descriptively analysed. In another application study, the evaluation of the goal attainment in the CMT form was compared with the success evaluation of the entire inpatient treatment.


Autonomic healing of coatings has been previously demonstrated using both capsule-based and vascular network approaches. However, healing in both systems has been limited to small damage volumes resulting from scratches or cracks. In this work, we demonstrate a system capable of regenerating a protective coating after large scale damage, for multiple cycles. Our bio-mimetic design incorporates pressure sensitive valves which open upon coating removal to release liquid (uncured) monomer onto the vascularized substrate whereby exposure to UV light polymerizes the monomer to form a protective barrier (coating). Results are presented summarizing coating regeneration performance as characterized by hardness recovery and resistance to abrasion. The evolution of coating formation is captured through optical microscopy. Multiple damage and regeneration cycles are demonstrated through repeated delivery of coating materials through the vascular substrate. Results from both ex-situ and in-situ regeneration tests are discussed. Specimens incorporating arrays of pressure valves for regeneration of larger scale damage are also presented. The autonomic flow valves are characterized by flow rate measurements as well as optical inspection. The influence of coating formulation, vascular pressurization, and environmental temperature are presented. The feasibility of using the sun as a source of UV light for curing the regenerated coating as well as the importance of valves as a mechanism for preventing backflow and channel blockage is discussed. By restoring their protective function autonomously, regenerative coatings could significantly increase the service life of coated substrates. Future design challenges such as the reduction of valve footprint, improved adhesion between the substrate and coating, and manufacturing scalability will be discussed.


A total of 75 shale samples from the Biyang Depression were analyzed with Rock-Eval, total organic carbon (TOC), organic maceral, and gas chromatography–mass spectrometry (GC–MS) techniques to reveal the effect of salinity on source rock formation and its control on the oil content. On the basis of the diversities in salinity and redox conditions reflected by the gammacerane/αβ C30 hopane (G/H) ratio, the pristine/phytane (Pr/Ph) ratio, and the extended tricyclic terpane ratio [ETR = (C28 + C29) tricyclic terpane/Ts)], three types (T1, T2, and T3) of shales were identified, which deposited in the brackish condition (G/H ratio 0.6), respectively. The comparisons among T1, T2, and T3 shales revealed that the salinity had a significant effect on the paleoproductivity of the lacustrine system. Most algae thrive in semi-saline conditions (T2) but are restrained in saline conditions (T3), so that moderate salinity con...


ABSTRACT The traditional image authentication technique generally determines the image attribution by extracting specific features and combining the similarity calculation algorithm. Because of the selected features dimensions, characterization and other factors, the accuracy and speed of image authentication have been restricted. In this paper, Recog-Net, an end-to-end image authentication model based on convolution neural network has been proposed. Deep residual network is chosen as the features extractor. Mahalanobis distance and threshold method are used to complete the image authentication. Experiments show that the performance of the extractor's features, compared with the traditional features and the features of other convolution neural network architectures, is more excellent, with a high degree of generality, recognition rate and robustness, still having these advantages even after a substantial compression. The Recog-Net for image authentication is able to accurately authenticate the images tampered with certain range.


Conventional error concealment (EC) algorithms for distributed speech recognition (DSR) share a common characteristic namely the fact of conducting EC at the vector (or frame) level. This strategy, however, fails to effectively exploit the error-free fraction left within erroneous vectors where a substantial number of subvectors often are error-free. This paper proposes a novel EC approach for DSR encoded by split vector quantization (SVQ) where the detected erroneous vectors are submitted to a further analysis at the subvector level. Specifically, a data consistency test is applied to each erroneous vector to identify inconsistent subvectors. Only inconsistent subvectors are replaced by their nearest neighbouring consistent subvectors whereas consistent subvectors are kept untouched. Experimental results demonstrate that the proposed algorithm in terms of recognition accuracy is superior to conventional EC methods having almost the same complexity and resource requirement.

The matrix converter is an AC-to-AC direct power conversion system that can generate variable voltage variable frequency output. There is a topology of Matrix converter having sinusoidal waveforms using output LC filter. It enabled that to provide lower EMI, lower common-mode current, and lower shaft voltage. However, there are some problems that filter size become bulky because of the restriction of switching speed using conventional power module, Silicon IGBT. Downsizing of input-output filter can be realized by employing SiC power devices since they are associated with low losses and can be operated at high frequency. In this paper, the use of SiC power devices in matrix converters is studied and its effect in reducing the size of the input and output filter is verified. A prototype was built for evaluations and the results are presented.


Email remains the primary method used to initiate an advanced attack or deliver ransomware because it can be highly targeted and customized to increase the odds of exploitation. Most anti-spam technologies mitigate against traditional spam and viruses, but lack the automated analysis needed to catch spam campaigns and more dangerous threats from the first time they're seen. This paper proposes a new multidimensional spam filtering framework based on threat intelligence. The framework collaborates and classifies multiple mail filtering technologies, using threat intelligence mail data as a training set, combines static and dynamic analysis, threat intelligence analysis, and behavioral intention analysis to establish a multi-dimensional decision tree to identify and trace high-level email attacks.


The capillary viscometer by discharging time is one of the commonly used viscometer. However, the measuring principle of the viscometer of this type is not yet established theoretically, especially the mean effective head of the viscometer is customarilly assumed to be independent on viscosity without theoretical verification. In this paper, considering some simplified models, it is proved theoretically that the mean effective head of a capillary viscometer depend on viscosity with exception of long enough capillary tube, even when the inlet correction of the capillary tube is assumed constant.


This work presents an experimental study of phonon transport in individual suspended single-wall carbon nanotubes (SWCNTs). Through the use of a micro fabricated device consisting of two adjacent suspended membranes, each with a platinum resistance heater and thermometer, the thermal conductance of several individual SWCNTs has been directly measured over the temperature range of 100 to 490 K. The effects of Umklapp phonon-phonon scattering remain weak and the thermal conductance remains roughly proportional to the calculated ballistic conductance throughout the temperature range. The macroscopic thermal conductance increases with temperature throughout the temperature range indicating static scattering processes or contact thermal resistance dominate transport in this regime. These results are an order of magnitude lower than the predicted ballistic thermal conductance calculated for a defect-free (18,0) nanotube. The results contrast with thermal conductance measurements reported using a high-bias DC self heating method. The discrepancy is discussed in terms of the differences in the contact thermal resistance, defects, and measurement methods.Copyright © 2008 by ASME


The invention relates to the field of metal solidification and continuous casting, in particular to a narrow copper plate with a funnel-shaped curved surface and a chamfered crystallizer. A working surface of the narrow copper plate (1) contacting molten steel comprises an intermediate area (2) and two chamfered areas (3 and 4) which are arranged at two sides, and is a funnel-shaped curved surface which is large in an upper part and small in a lower part. By the narrow copper plate with the funnel-shaped curved surface and the chamfered crystallizer, the uniformity of a cooling effect of a chamfered surface can be ensured, and the service life of the narrow copper plate and a side chamfer can be prolonged.


Recent advances in optical technology have taken fluorescent imaging beyond the standard two-dimensional (2D) epifluorescence imaging into the realm of three-dimensional (3D) fluorescence molecular tomographic (FMT®) imaging for improved localization and quantification in deep tissue. This requires the transillumination of animals (i.e. the passing of light through the animals) rather than the standard surface illumination used for epifluorescence assessment. This advance brought by fluorescence tomography is accompanied by the need for extra care in performing proper imaging. Experimental animals must be prepared for transillumination imaging by hair removal, must be properly injected with imaging agents for optimal delivery to imaging sites and minimization of artifacts, and scans must be set up and acquired under optimal conditions and settings. This technical note provides both the in depth details on performing proper imaging as well as data examples to illustrate the ramifications of suboptimal experimental procedures. Performed properly, the pairing of powerful, deep tissue FMT imaging with appropriate near infrared (NIR) imaging agents allows the detection and quantification of important biological processes, such as cellular protease activity, vascular leak, and receptor upregulation, by accurately reconstructing the in vivo distribution of systemically-injected NIR imaging agents. The ability to use fluorescent imaging agents that detect and quantify a variety of biological activities is already expanding the horizons of pre-clinical research and drug development.

"We both agree that the mind is the measure of the individual; the quality of life as it reaches its zenith in time may be determined by mental content and meaningful activity," Dr. Bortz (1) wrote to me when he invited me to discuss motivation as a health resource, before our Society. Thus did Dr. Bortz succinctly paraphrase another eloquent and eminent American physician, Dr. Benjamin Rush (2), who in 1789 in an extremely interesting essay "On Old Age" had the following to say: "It has long been an established truth, that literary men (other circumstances being equal) are longer-lived than other people. But it is not necessary that the understanding should be employed upon philosophical subjects to produce this influence upon human life. Business, politics, and religion which are the objects of attention of men of all classes, impart a vigor to the understanding, which, by being conveyed to every part of the body, tends to produce health and long life." The wisdom of the foregoing remarks and their applicability to modern psychosomatic concepts is unassailable. What remains is the never-ending effort to put into practice these theoretical considerations. Both Dr. Bortz and Dr. Rush imply that of all living creatures man alone has the God-given gift of mentation and imaginative capacities. These give man the unique opportunity to influence his environment, help shape his own future, affect the course of his life, and effect the inevitable. Thus, man of all living matter, actually has the freedom to act and to "choose" between success and failure, health and disease. Real freedom of action or freedom of choice, however, is given only to a few. For choice, as the psychiatrist sees it, is dependent not only upon the conscious evaluation of any given situation but more cogently upon the unconscious motivation underlying the apparent thought processes. Indeed the voice of the intellect is soft when pitted against the tumultuous clamor of the individual's unconscious emotional stresses and drives. It is only when one is aware of one's unconscious motivations and one acts in concert with them or takes a firm stand against them, that one can be said to have a free choice. Successful living is therefore a product of the utilization of the proper emotional motivation. In later life the will to live and adapt to stressful life situations (which is the real measure of health) is often undermined by unconscious drives which are


A 3-year Department of Energy Environmental Science Management Program (EMSP) project is currently investigating natural attenuation of trichloroethene (TCE) in aerobic groundwater. Determining whether TCE degradation occurs at meaningful rates under aerobic conditions via biological cometabolism has important implications for the assessment of natural attenuation. This presentation summarizes the results of a screening process to identify TCE plumes at DOE facilities that are suitable for assessing the rate of TCE attenuation under aerobic conditions. In order to estimate aerobic degradation rates, plumes had to meet the following criteria: TCE must be present in aerobic groundwater, a conservative co-contaminant must be present and have approximately the same source as TCE, and the groundwater velocity must be known. A total of 127 TCE plumes were considered across 24 DOE sites. The four sites retained for the assessment were: 1) Brookhaven National Laboratory, OU III; 2) Paducah Gaseous Diffusion Plant, Northwest Plume; 3) Rocky Flats Environmental Technology Site, Industrialized Area – Southwest Plume and 903 Pad South Plume; and 4) Savannah River Site, A/M Area Plume. The analysis indicates that TCE is being preferentially attenuated at environmentally significant rates under aerobic conditions with degradation half-lives ranging from 0.85 to 12 years in 8 of the 9 plumes evaluated.


Cascaded H-bridge Rectifier (CHBR), the key component of Power electronic transformer, is faced with the challenge of DC-link voltage balance. This paper proposes a DC-link voltage balance strategy realizing it by Logic Combination Modulation (LCM). The mathematic model of the topology, the control strategy of three-phase CHBR, and basic modulation of the cascaded converter have been designed. The theoretical analysis, simulation, and experiment have been done to verify the stability, effectiveness of the proposed strategy. Also, the limitation of the proposed strategy is calculated and proved. The LCM could balance the DC-link voltage while one module is no-load under 0.83 modulation depth.


Abstract Background Health care workers employed in the COVID‐19 emergency are at a high risk of stress. Aims and objectives To explore the mediating roles of self‐efficacy and resilience between stress and both physical and mental quality‐of‐life components in intensive care nurses during the COVID‐19 pandemic. Design Cross‐sectional survey design. Methods The stress subscale (depression, anxiety, and stress scale in Spanish Scale, DASS‐21), the summary components (physical and mental) of health‐related quality of life (SF‐36), the general self‐efficacy scale (GSES), and the resilience scale (RS‐14) were administered in 308 intensive care nurses. Serial multiple mediator models were used. Results There was a significant indirect effect of levels of perceived stress on both physical and mental health components through self‐efficacy and resilience. Specifically, greater perception of self‐efficacy was associated with a lower perception of stress and greater resilience, while higher resilience was associated with greater physical and mental health (B = −0.03; SE = 0.02; 95% confidence interval [CI] = [−0.07, −0.01]; B = −0.03, SE = 0.01, 95% CI = [−0.07, −0.01], respectively). It was observed that self‐efficacy alone also mediates the relationship of the perception of stress on the components of physical and mental health (B = −0.07; SE = 0.05; 95% CI = [−0.18, −0.03]; B = −0.09; SE = 0.04; 95% CI = [−0.17, −0.24], respectively). However, resilience alone was not a significant mediator of these associations. Conclusions It can be concluded that stress is linked to the physical and mental health components related to quality of life through self‐efficacy and resilience. Relevance to clinical practice These psychological resources would allow the nursing staff to maintain a good quality of life despite high levels of stress. These findings have implications for future research in terms of both model testing and clinical application.


Objective: This study was designed to explore the benefit of curcumin as adjuvant therapy to the standard Helicobacter pylori eradication triple therapy in both duodenal and gastric ulcers patients. Methods: The present study enrolled 40 patients newly diagnosed endoscopically with peptic ulcer disease to be allocated into group 1 treated with standard H. pylori eradication triple therapy, and group 2 patients treated with curcumin (500 mg) capsules three times daily for 14 days as an adjuvant to standard triple therapy. Stool antigen test, immunoglobulin M serology test, tumor necrosis factor-alpha (TNF-α), interleukin 1 beta (IL-1β), and total antioxidant capacity (T-AOC) are measured at the baseline and after 6 weeks of treatment. Results: The result showed that the use of curcumin as adjuvant therapy produced highly significant improvement in healing efficacy which was significantly distinguished in duodenal ulcer patients compared to gastric ulcer groups 2 patients (p<0.05), along with a highly significant reduction in pro-inflammatory IL-1β level in group 2 patients (p<0.01). After 6 weeks of treatment, there was a highly significant elevation in the level of TNF-α in groups 1 (p<0.01), though group 2 patients presented with non-significant elevation in TNF-α level. Moreover, the T-AOC was improved with curcumin adjuvant therapy, though non-significant, compared to group 1 patients who showed a reduction in T-AOC. Conclusion: This study revealed that addition of curcumin as adjuvant therapy produced improvement in ulcer healing efficacy, and controlled the inflammatory and oxidative stress process induced by H. pylori infection.


A liver‐humanized mouse model for CPS1‐deficiency was generated by the high‐level repopulation of the mouse liver with CPS1‐deficient human hepatocytes. When compared with mice that are highly repopulated with CPS1‐proficient human hepatocytes, mice that are repopulated with CPS1‐deficient human hepatocytes exhibited characteristic symptoms of human CPS1 deficiency including an 80% reduction in CPS1 metabolic activity, delayed clearance of an ammonium chloride infusion, elevated glutamine and glutamate levels, and impaired metabolism of [15N]ammonium chloride into urea, with no other obvious phenotypic differences. Because most metabolic liver diseases result from mutations that alter critical pathways in hepatocytes, a model that incorporates actual disease‐affected, mutant human hepatocytes is useful for the investigation of the molecular, biochemical, and phenotypic differences induced by that mutation. The model is also expected to be useful for investigations of modified RNA, gene, and cellular and small molecule therapies for CPS1‐deficiency. Liver‐humanized models for this and other monogenic liver diseases afford the ability to assess the therapy on actual disease‐affected human hepatocytes, in vivo, for long periods of time and will provide data that are highly relevant for investigations of the safety and efficacy of gene‐editing technologies directed to human hepatocytes and the translation of gene‐editing technology to the clinic.


Traumatic impairment of peripheral nerves in the limbs requires multimodality treatment including physiotherapy, chemotherapy, orthopedic methods, massage, manual therapy. The above complex produced responses in the majority of patients treated.


Inclusive education and the activities of the assistance centers – Núcleos de Apoio às Pessoas com Necessidades Especiais – in the Federal Institute of São Paulo Assistance centers called Núcleos de Apoio às Pessoas com Necessidades Educacionais Específicas (Napnes) have been serving as reference in the education of students target-audience of special education (in Portuguese, estudante público-alvo da educação especial, acronymed PAEE) in the context of the Rede Profissional e tecnológica. These centers have also carried out different initiatives within the context of the Federal Institute of São Paulo (IFSP). Thus, studies on the inclusion of PAEE students on federal institutes (IFs) and on issues related to teaching planning, their accessibility and permanence prove to be the more relevant. This study aims to map and analyze initiatives developed or experienced by Napnes' teams from the different IFSP campuses, regarding the assistance center's activities proposal. This is a qualitative and documental research, and the contents of the journal titled Napne em Ação were analyzed. Its first edition was published in 2015 and was composed by the annual reports of the activities carried out in the campuses. Institutional documents which regulate the activities performed by Napnes were also analyzed. The journal's 302 pages were organized in quantitative information and analyzed qualitatively, divided in thematic axes. Data indicate that, analyzing IFSP as a whole, teaching, research and extension initiatives related to the PAEE students were carried, which fulfills the objectives in the center's activities proposal. Actions related to the different specificities were also carried out, with emphasis on deaf students, with the addition to those aimed at employee training. It is understood, through the individual analysis of each campus, that there are initiatives being carried out and that the proposal for school inclusion has not been stagnant since 2014. However, there is


Two compounds of stoichiometry Cu(CH3COO)2·L (L=triphenylphosphine or triphenylphosphine oxide) were prepared. These compounds display the antiferromagnetic behavior typical of dimeric copper(II) carboxylates. The singlet-triplet splitting energy is 371 cm−1 for the phosphine adduct and 319 cm−1 for the phosphine oxide adduct.


To study the hyporhic zone of Shifosi reservoir in the conversion process between the three main pollutants nitrogen, this paper applied HYDRUS-1D software to simulate 200cm of soil profile depth in 200 hours mutual transformation behaviors. Results show that interact in complex environment and microbial flora, under the action of the 105cm of ammonium nitrogen and nitrite-nitrogen fully translated into nitrate-nitrogen, 200cm nitrate-nitrogen denitrification process almost completely converted into nitrogen gas.


A combined air-conditioning system of displacement ventilation and cooled ceiling was introduced,the characteristics of indoor air quality improvement and the human's thermal comfort satisfaction were analyzed,and the energy saving effect and economic traits were evaluated.


The potential use of a solid phase sorbent prepared via immobilization of salicylaldoxime on a silica gel surface for the purpose of preconcentration, removal, or recovery of Ni(II) from the aqueous phase has been investigated. The efficiency of the solid phase thus synthesized was evaluated by an equilibrium sorption study of Ni(II) in both the static and dynamic modes. The process is dependent on length of shaking period, agitation speed, adsorbent dose, pH, temperature, and flow rate of the feed solution. The adsorption data were fitted to the Langmuir adsorption isotherm model. The negative-free energy change indicates the process to be favorable. The process was found effective for the removal and recovery of nickel ion from samples of various origins such as synthetics, industrial waste, and alloy. A 90% recovery and a 40-fold preconcentration factor were obtained for Ni(II) solutions of different concentrations up to 200 mg dm - 3 . Merit of the process lies in its ability to determine trace amounts of nickel from a large sample volume following preconcentration. At optimized conditions, the process is selective and can be used in the presence of other metal cations. The analytical data for the nickel content in the alloy sample NBS SRM-94C using the proposed method are comparable to certified value. The process is efficient, selective for nickel ion, and can be used without separating other constituents present in the sample matrix.


A high-power dual-wavelength laser based on coaxial end-pumping scheme with composite Nd:YAG and Nd:YAP crystals was demonstrated. A theoretical model was built to analyze the thermal lens and accurately calculate the thermal focal length of laser gain medium pumped by a divergent beam. The experiment was carried out with a plane-convex cavity and a V-shape cavity for high-power output. The Q-switched laser produced 9.1 W pulsed dual-wavelength output (4.7 W at 1064 nm and 4.4 W at 1079 nm) at 25-kHz pulse repetition rate with synchronized pulse duration of 35 ns, corresponding to the optical-to-optical efficiency of 30.3%. The continuous-wave (CW) output power reached 15.5 W at laser diode (LD) pump power of 40 W, corresponding to a slope efficiency of 40.9% and an optical-to-optical conversion efficiency of 38.9%. The powers at two wavelengths were almost equivalent and the fluctuations were both less than 2.3%. To our best knowledge, it was the highest output power for stable CW dual-wavelength lasers based on diode-end-pumped configuration.


Variational principles applied in Physics look structurally different for reversible and irreversible processes, especially with respect to the time variable. This, in a sense, is one of the central problems of Non-equilibrium Thermodynamics. The formal difference is, however, not a mathematical necessity, there exists a common frame which we present here: It is shown that for any equation that can be composed by the application of a linear operator on a given function of the unknown function, there exists a method of construction of a Lagrangian and a potential function, so that the variational problem of this Lagrangian of this potential gives the original equation as the Euler-Lagrange equation (if the original unknown function is related to the potential in the given way). This construction of the Lagrangian-Potential pair (if it exists) contains an arbitrary function. The method is extended to the case when the equation can be constructed by the composition of linear operators and given functions in a finite number of steps. The method gives a common basis for approximation methods of Ritz and Galerkin type and also a modification of the latter which (not like the original method) provides natural boundary conditions to the problem. Examples of the Lagrangian are given for several equations of Physics. They include for the linear case: the damped linear oscillator and the equations of the wave approach of thermodynamics; for the nonlinear case we consider Maxwell's equations with Ohm's law and an arbitrary polarization function. Another example considered is a multicomponent diffusion system with second order chemical reactions. Examples of the construction method also are given for nonlinear cases: a nonlinear heat conduction equation, and equations of multicomponent diffusion with non-constant transport coefficients. * Address for correspondence.

This paper aims at improving the contouring accuracy in biaxial position control systems. A quadratic cost functional consisting of the contour error is formulated including both axes of the system. Linear constraints on the motor voltages and currents are considered. Modeling of the driving motors including the often neglected current dynamics enables precise position control. Even constraints on the contour error can be considered, e.g. to meet manufacturing tolerances. This so called model predictive contouring control is employed in a control structure consisting of a reference governor which adapts the path reference in order to meet constraints and a subordinate unconstrained controller for precise tracking of the reference. This flexible structure is simple to tune and makes it possible to decouple the computationally complex optimization from the subordinate controller.


We study the probability of detecting the bitstream of a 2 × 1 SIMO polarization-diversity system with co-located orthogonally polarized antenna ports on the receiving side of a free-space propagation environment with arbitrary angle-of-arrival, i.e., in so-called Random-Line-Of-Sight (Random-LOS) propagation environments. We show how the diversity gain degrades in directions where the two orthogonal ports have non-orthogonal far-field functions or an amplitude imbalance. We also show that the system performance is better when one side of the link is circularly polarized and the other side is linearly polarized.


The case is considered where low-intensity seed radiation at a frequency close to that of the second harmonic is injected into an optical fiber in addition to the pump radiation. The seed signal is predicted to undergo exponential amplification. The gain has a resonance dependence on the frequency shift. It is shown that the nonlinearity associated with a decrease in the relaxation time taking place with increasing second-harmonic intensity leads to the signal saturation and broadening of the resonance profile. The relation of this effect with the well-known phenomenon of photoinduced second-harmonic generation (SHG) in an optical fiber is discussed. 16 refs., 1 fig.

Detailed multiproxy (lithology, micropaleontology, palynology) study of a 455 cm thick marine sediment sequence overlying the Moscovian till exposed in Bychye-2 section on the Pyoza River allowed for reconstructing past environmental changes during the Boreal transgression. Stratigraphic subdivision is based on the succession of local palynological zones that were correlated with previously established regional zones. The latter are constrained on the basis of correlation with the West European palynological zones. Marine sediments of Bychye-2 section accumulated from the end of the Moscovian glacial (>131 ka BP) until ca. 119,5 ka BP. Five ecological zones were established in the section in accordance with the upward trends in the changes in lithology and variability in the taxonomic composition of fossil assemblages of benthic foraminifers and ostracods and associations of marine dinocysts and freshwater green microalgae. Taken together, they are indicative of the progressive shallowing of the basin under the improving climatic conditions, which primarily influenced the degree of sea-ice cover extent. Three successive phases in the evolution of the Boreal transgression have been identified: 1) a seasonally sea-ice covered relatively deep freshened basin of the initial phases of flooding (455-360 cm, >131-130,5 ka BP); 2) a deep basin of the maximum phase of flooding with less extensive sea-ice cover (360-290 cm, 130,5-130,25 ka BP); 3) a shallow basin with reduced seasonal sea-ice cover (290-0 cm, 130,25-119,5 ka BP). The flooding of the territory with cold Arctic waters was rapid, as evidenced by the composition of microfossil assemblages represented by river-proximal Arctic species in combination with the species that prefer water depths of at least 40-50 m. The regression in the region started about 130 ka BP, which indicates that the glacioisostatic rebound of the territory was ahead of the global eustatic sea level rise. The most warm-water and taxonomically diverse assemblages of foraminifers and ostracods, containing species typical of the Baltic Sea, were recorded during the regressive stage, especially in the time interval of ~128-124 ka BP. This probably gives evidence for a rather long-lasting connection of the White and Baltic seas.

Purpose – The purpose of this study is to find a concept for optimizing cost and revenue from providing private accommodation services. The aim is to display how linking all participants who provide private accommodation services into a logistics network will result in better and higher quality service for the guest and in reduced cost for the private accommodation provider. Design – This study researches private accommodation providers in the Primorsko - Goranska County. Primorsko - Goranska County has great potential for providing private accommodation services, but it does not have a well-organized system which could improve the quality of the provided services. Methodology – To prove the study's thesis, scientific methods of analysis, synthesis, methods of induction and deduction, as well as historic and statistical methods have been employed. Furthermore, it includes data from the Department of Tourism, Office of the Croatian Government in Rijeka, as well as data obtained from the local Association of Private Accommodation HGK – PGŽ (Croatian Chamber of Economy in the Primorsko – Goranska County), data from the statistical yearbook, Institute for tourism as well as data from the Croatian Ministry of Tourism and other scientific and professional literature. Approach – The authors aim to prove that by linking all participants in the process of providing private accommodation into a logistics network would increase the quality of the service and simultaneously optimize the costs. The logistic solution which will be proposed in the "Results" section will provide answers to the suggestion whether private accommodation providers should enter into a system with its business surroundings, i.e. travel agencies, local administration community systems, tourist boards, commercial service associations, state institutions, etc. Findings – This research has reached the conclusion that private accommodation providers do not satisfy the principles of the logistic concept and that other participants in the process of providing private accommodation services (institutions) do not adequately support them. The logistic concept is not the final solution, but a foundation for further research. Originality of the research – This paper represents a valuable contribution to research into private accommodation as a phenomenon in the accommodation structure and accommodation services at the level of the Primorsko – Goranska County as well as the Republic of Croatia as a whole. A logistic concept is provided which could solve the problem of poor organization that many private accommodation owners face and it could also possibly have a practical effect on both private accommodation owners and managers. The paper also enriches the overall amount of scientific literature in the field of logistics, organization and management in tourism.


On the basis of the theories of baroclinic vorticity development,this paper discusses the conversion of horizontal vorticity into vertical vorticity in the large-scale motion of the atmosphere,and then the conversion terms is employed to describe the evolvement of the summer monsoon.We extract the terms of horizontal vorticity conversion from the equation of vorticity in the p coordinates,which is the main component of the baroclinic vector of large-scale atmosphere in the middle-upper troposphere,and then conclude that the conversion term is able to reach the same order with that of the local variation of the vertical vorticity when the large scale precipitation takes place in the summer monsoon period in China.By analyzing and calculating the GAME reanalysis data from April to August in 1998 in the monsoon region of Chinese mainland,we also found that the conversion term is important to the large-scale cyclone developing above the 600hPa,and also indicative of the onset of the South China Sea summer monsoon(SCSSM) and the development of Jianghuai meiyu.After the onset of SCSSM,the magnitude of the conversion term is correlated with the brisk and intermittence of the summer monsoon,and its changes also reflect the movement regularity of the West Pacific subtropical high(WPSH) over the mainland.Therefore it may be a convenient way to employ the baroclinic terms in researching influence of the moist weather processes on the short-medium range change of the WPSH and the atmospheric circulations.


In this work a generalized Pauli's theorem (proved by D. S. Shirokov for two sets $e^a, h^a$, $a=1,...,n$ of Clifford algebra elements $Cl(p,q)$, $p+q=n$) is extended to the case, when one or both sets of elements depends smoothly on points $x$ of the Euclidian space. We prove that in this case for any point $x_0$ of Euclidian space there exists $\epsilon$-neighborhood $O_\epsilon(x_0)$ and there exists smooth function $T : O_\epsilon(x_0)\to Cl(p,q)$ such that two sets of Clifford algebra elements are connected by a similarity transformation $h^a(x)=T(x)^{-1}e^a(x)T(x)$, $a=1,...,n$ in $O_\epsilon(x_0)$.


Abstract Homing behaviour in the New Zealand long‐tailed bat (Chalinolobus tuberculatus), a temperate insectivorous species, was investigated at Grand Canyon Cave, central North Island. A pilot study of nine adult male bats was conducted to determine whether use of the cave was regular enough for a homing study. Eight bats returned to the cave over the 3‐week monitoring period, six on the night following release. Nine additional bats carrying radio transmitters were then released at three sites (three at each site) c. 5, 10 and 20 km due east of the cave; sites estimated to be located within, on the border of, and outside the population's known familiar area respectively. All but one of these nine bats were subsequently detected at the cave. Results suggest that adult long‐tailed bats are able to return home following displacement both inside and outside their familiar area. Implications of these findings for translocations of bats and the possession of a potential long‐distance navigation system by this species are discussed.


High-level backbone talents of ethnic minorities are the important driving force in China's western development strategy,and information technology is the powerful guarantee of their performance of ability. The shortcomings of previous information technology course teaching are summarized. Based on these shortcomings and the characteristics of students,"application-oriented and demand-based"curriculum reform idea is put forward. According to the research on the students' information technology and their needs,as well as the teaching requirements of higher education,innovative reforms have been carried out on course content setting,teaching modes,teaching methods and evaluation methods,and especially the model-driven task-based teaching and student group management should be promoted. Good results have been achieved in teaching practice.


Digital Signal Processing (DSP) and multimedia workloads are expected to be the dominant workloads on future computer systems. This is true in both low cost embedded applications that use specialized microprocessors like DSPs and in the generalpurpose processor market. Very Long Instruction Word (VLIW) architectures have multiple functional units to take advantage of vastly available Instruction Level Parallelism (ILP) in such applications. Single Instruction Multiple Data (SIMD) techniques operate on multiple data in a single instruction (exploiting data parallelism). This paper proposes to evaluate the benefits of using the above two techniques for DSP and multimedia applications. Using a modern commodity processor from each category – Texas Instruments Inc.'s TMS320C6x (VLIW) and Intel's Pentium II with MMX (SIMD), several DSP and multimedia benchmarks will be evaluated.


Development changes in the organization of information within the mammal domain were examined and considered within the context of cultural knowledge acquisition. Judgments of similarity among mammals were elicited from 7-year-olds, 10-year-olds, and adults by means of a triad task. Analyses addressed both quantitative and qualitative models of development consistent with Romney, Weller, and Batchelder's (1986) cultural consensus model. Results provided partial support for both models. Ss' responses generally fit the cultural consensus model, whereas systematic patterns of deviation from the model emerged between children and adults because of the emergence of a primate category after age 10. The relationship between these results and Carey's (1985) research on the development of biological knowledge is discussed, and implications for the study of expertise acquisition are considered

Polyazines, H/sub 2/N single bond (N double bond C(CH/sub 3/) single bond C(CH/sub 3/) double bond N)/sub x/ single bond NH/sub 2/, of various chain lengths have been prepared and studied by IR spectroscopy. An x-ray crystal structure was done on the monomer of this series, 2,3-butanedione dihydrazone (x = 1). It crystallized in space group P4/sub 2//n with cell constants a = 12.172 (3) A and c = 4.115 (1) A and Z = 4; intensity data were collected from 3.0/sup 0/ less than or equal to 2theta less than or equal to 65.0/sup 0/. The monomer is planar with long carbon nitrogen double bonds (1.291 (1) A) in the E conformation, the methyl groups are anti across the short carbon-carbon single bond (1.474 (2) A), and the lone pairs across the nitrogen-nitrogen single bonds are gauche. The anomalous bond lengths indicate a degree of ..pi..-bond conjugation in this molecule. The higher molecular weight materials are yellow to brown powders, are stable to air, have high melting points, and are surprisingly resistant to hydrolysis. Correlation of IR spectra of the monomer and sequentially increasing chain length polymers shows that the highest molecular weight material is at least 45 monomermore » units long and is planar with double bonds in the E conformation and all single bonds in the anti conformation. As in the monomer, the position of the C double bond N resonance indicates conjugation of the ..pi.. system along with polymer chain.« less

mechanisms of incorporation into soil." (DFG: SCHA 849/13)


A general method for isoxazoles from readily available ynones using trimethylsilyl azide as an amino surrogate, likely via an unprecedented hydroazidation of the alkyne and denitrogenative cyclization, is demonstrated. The method neither required any catalyst nor demanded unusual conditions to afford the products with outstanding functional group compatibility.


A batch of chilled nodular iron camshafts were broken during assembling.The reasons of broken were analyzed on the cracking position,fracture observation by SEM and microstructure inspection.The results show that Cr exceed content and low pouring temperature created large amount of carbide,even whole cam became white iron.They also weaken the mechanical properties of camshafts production,causing a batch of camshafts broke.Some technical measures were taken,on the control of chemical and pouring temperature and inoculations well as on the change the size of chills and heat treatment parameters,to improve the graphite morphology and the mechanic performances.


A large variety of dienophiles, including electron-rich and -deficient 2π components, undergo the title reaction of hydrazones (I) or (XVII) to give the desired pyridazines, and in some cases open-chain hydrazone derivatives.


When purchasing a potted Easter lily, select a high quality plant. Select a well-balanced plant that looks attractive from all angles. The rich green leaves should be dense and plentiful from the top down to soil level. Look for a lily with one or two open or partly opened flowers and three or more unopened buds. The puffy buds will open up within a few days, while the tighter ones will open over the next several days. Choose an Easter lily plant that has one or two partially open flowers and three or more unopened buds so the plant will have a longer blooming time. Barbara H. Smith, @2016 HGIC, Clemson Extension


Condensed heterocyclic systems containing N& S-medium-sized rings, in particular, thiazepine, thiazocine, and thiazonine systems are important substructures present in a large variety of biologically active natural products. Methods for the formation of thiazonines and higher ring systems, however, remain largely unknown. The research presented addresses the synthesis and characterization of new heterocyclic skeletons incorporating N& S-medium-sized-rings fused to quinolines to form the targeted tetracyclic 1,4-thiazocines, 1,4-thiazonines and 1,4-thiazecines by Friedel-Crafts cycliacylation and Beckmann-rearrangement sequences. The ambient conditions, short-reaction times and easy work-up procedures make this synthetic strategy a better protocol for the synthesis of medium-sized heterocyclic rings bearing nitrogen and sulphur atoms.


Nursery habitats provide increased survival and growth and are a crucial early life-stage component for many fish and invertebrate populations. The biogenic structures that provide this nursery function, however, are increasingly degraded. Therefore, any effort to conserve, restore or replace habitat with artificial structure should be guided by an understanding of the value provided by that nursery habitat. Here we experimentally manipulated structure across a number of sites by inserting pinnind bivalve mimics into the seabed and deploying video cameras to observe the response of post–settlement stage snapper, Chrysophrys auratus (Forster in Bloch and Schneider 1801). We also collected a range of environmental variables across these sites to determine the relative importance to snapper of benthic vs. pelagic productivity. While the abundance of snapper was low, our results demonstrated a strong association to structure relative to control plots. The environmental variable with the highest correlation to snapper abundance was the abundance of zooplankton eaten by snapper. This result was well supported by the dominance of zooplankton over small benthic invertebrates in snapper gut contents, and the weak influence of benthic infauna in our regression models. These regressions also demonstrated that when combined with zooplankton abundance, turbidity had a negative relationship to snapper abundance. This highlights the importance of relatively clear water in estuaries, which allows post–settlement snapper to more efficiently consume the zooplankton that are present in the water column. The third component that post–settlement snapper require is of course the presence of benthic structure. While benthic habitat structure was the strongest factor affecting juvenile snapper abundance, we did not find any correlations to suggest that this importance was related to energetic sheltering and access to locations with high food flux.

This research aimed to assess forested land with Guadua cane through the ecosystem service "water capacity" in the Calada-Chone community, as a conservation strategy comprised four stages. In the first, an environmental, social and economic diagnosis of the study site was carried out, during the dry season, which included: the application of a questionnaire to the residents of the Calada community; comparisons between current and previous years maps of the study area; and identification of the water sources available in the forested soil with Guadua cane. In the second stage, the hydric capacity of forested and non-forested soil with Guadua cane was determined comparatively in the dry season, where soil samples were collected and analyzed, to know the levels of organic matter content, texture and water capacity in dry season. In the third stage, the environmental, social and economic value of the water capacity in the forested soil with Guadua cane was weighted. Finally, in the fourth stage a strategy was established for the conservation of the forested soil with Guadua cane. It was found that there are significant differences (p <0.05) between the forested land with guadua cane and the non-forested land, for the three parameters analyzed; which indicates that the forested land with Guadua cane has a greater environmental, social and economic value.

Abstract There are many nineteenth century books in European languages with actual photographs pasted in, but a Persian book, printed lithographically in Bombay 100 years ago and carrying actual photographs of no less than six heads of state, five of them European, must be ranked as a curiosity. The title-page of the book does justice to the florid style of Persian favoured by the Shahs: (in translation) 'A Relation of Some of the Events in the Life of King N' asiruddin Shah of the Qajar Dynasty, Including Some of the Beautiful Poems Written by Him and a Narrative of his Travels.' This is followed by the grandiloquent and long-winded title of King N'asiruddin Shah, who ruled Iran from 1848 until his assassination in 1896. As is usual with Oriental works of the time, particulars of the printing are given in the colophon at the end of the book. It states that the volume was printed in House No. 128, Mohalla Umarkari, Bombay, in Moharram 1302 Hijri, that is to say, in the year 1885.


The researches on the relationship between Japanese moral education and modernization gradually emerged with the development of the researches on Japanese modernization and changed its perspectives with the paradigm change of modernization researches.The researches on the relationship between Japanese moral education and modernization can be generally divided into three phases.Up to now researches on the relationship between Japanese moral education and modernization have put forward some inspiring and provoking views from different perspectives,but there are still a lot to be researched.


Indicators, such as the energy balance (EB) and greenhouse gases emissions avoided (GHGEA), are frequently used to evaluate the benefits and sustainability of biofuels. Many important papers and reports have been published in recent years to demonstrate the environmental and energetic benefits of biofuels, such as ethanol from sugar cane. EB and GHGEA often include other sugar cane products, such as electricity and bagasse. The anaerobic digestion of vinasse can generate considerable amounts of biogas but is not a common practice in Brazil. This study evaluates the potential benefits to the EB and GHGEA of ethanol by the production of biogas from vinasse and its use to produce electricity or biomethane. Biomethane can be injected on the Natural Gas Grid or used as a fossil diesel oil replacement in the mill operations of harvesting and transportation of sugar cane. The results show that biogas from vinasse can represent improvement in both indicators, which ranges from 3.5% improvement in EB by electricity generation with biogas to 27.5% improvement in GHGEA by replacing diesel in the mill operations. © 2019 American Institute of Chemical Engineers Environ Prog,39:e13226, 2020


familiar institutions that outsiders rely on to structure their knowledge' (p. 4). Newbury's characterization of the Kivu Rift Valley as a 'frontier zone' separating the forest cultures of the Congo basin to the west and the highland states of the Great Lakes to the east informs his analytic approach in crucial ways. Rather than viewing frontier zones as marginal areas subject to incursions and influence from centers of political power, Newbury regards these often overlooked areas as 'zones of creativity' that fundamentally shaped the development of the region's well-known centralized states. Throughout the essays in The Land Beyond the Mists, he convincingly demonstrates that ' in historical terms regional social innovations were derived as often from the perimeter – from the marginalized, those thinking and acting outside of prescribed conventional norms – as from the center' (p. 7). Newbury arrived at this critical insight through meticulous research and painstaking analysis conducted over several decades; his body of work has guided subsequent historians of the Great Lakes region and will undoubtedly continue to do so for many years to come. The relevance of The Land Beyond the Mists, however, stretches well beyond the Great Lakes region. The original publication of the essays in this collection coincided with the development of African history as a professional discipline in North America. When read together as a single body of work, they therefore offer the rare opportunity to trace the shifting intellectual concerns that have animated this development through the career of one of the discipline's most accomplished practitioners.


In 8 of 24 children with proteincalorie malnutrition, basal serum immunoreactive thyrotropin (TSH) is elevated, and the TSH response to synthetic thyrotropin-releasing hormone, while prompt, is exaggerated and sustained, showing a delayed peak in 8 of 19 tests. After 3 weeks of treatment, basal TSH in most cases drops towards normal, peak TSH responses are lower (yet remain exaggerated in 4 instances), but the sustained TSH secretion returns to normal in all patients. In all of 5 cases tested, exogenous triiodothyronine suppresses basal TSH. This suggests a minor impairment of thyroid function in some children with protein-calorie malnutrition. TSH reserve, however, appears normal.

In this study, two fish pathogenic bacteria (Yersinia ruckeri, Lactococcus garvieae) challenged with U. crassus for the pathogenicity characteristics onto mussels were investigated. For this purpose, 10 bacteria mL were mixed in the water. Mussels were removed turbidity of the water and throw the bacteria as pseudo feces. No mortality and no symptoms of U. crassus were noted from any of the groups during observation period. Also, the pathogens were not isolated from the mussels.


The focus of this study is to design a combustion system able to sustain hypersonic flight at Mach 8. A Dual-Mode Free-Jet combustion chamber design, first tested in 2010 by NASA, is being adapted to run on hydrogen fuel instead of ethylene while addressing the excessive thermal heat load. This study is part of the FAME (Flight at Mach Eight) project, with the primary objective to design and analyse the engine configuration for a hypersonic commercial aircraft. This CFD analysis and validation study, the first to replicate this combustion chamber design, provides detailed instructions on the combustion system design. The analysis from this study can be used for future research to successfully reach a sustainable design and operation of a Dual-Mode Free-Jet combustion chamber. The 53% size reduction in the combustion system represents significant progress which encourages future research regarding in the design of combustion systems for hypersonic propulsion systems.


Evidently, the COVID-19 pandemic forced football fans the world over to abstain from attending football matches, yet racism from football did not eclipse for it became more prevalent on online platforms. Karl Planck wrote in 1898 an essay on football, I Fusslümmelei i , which reflected his perceived ugliness of the game.[1] The physical education professor from Germany despised the game and its English origins. This special issue addresses football-related online racism and brings to light several disturbing incidents that have scarred football, not to mention the extent to which they have undermined the integrity of the popular game.

Simon Richter and Richard Block, eds., Goethe's Ghosts: Reading and the Persistence of Literature. Rochester, NY: Camden House, 2013- 315 pp.,7 ills.The objective of this essay collection is to examine how the institutional role of literature may or may not be affected by various "ghosts." By "ghosts" the editors mean both the ghosts depicted in Goethe's works and "the ability of literary ghosts through their haunting ways to convey meanings and forms of meanings long past" (3). Coeditors Simon Richter and Richard Block set the scene in their introduction by referencing Mikhael Bulgakov's novel The Master and Margarita, in which an apartment houses multitudes of demons and ghosts. For Block and Richter this haunted apartment stands in for a "house of literature" in which "we can find entire and largely forgotten regions of non-normative representations and subject positions" (2). The contributors to this volume explore, each in his or her own way, these haunted aspects of literature, in particular Goethe's literature. But the scene from Bulgakov's novel also conjures up an eagerness to examine responses to literature in the spirit of Jane Brown's research. According to Brown, Goethe recognized the cultural wealth about to be lost and strived to recover and preserve the old traditions. Most of the essays in this collection engage with Brown's discourse, each taking on the issue of the persistence of literature and exploring the dark corners of the house of literature. Coeditors Block and Richter dedicate the volume to Jane Brown, whom they deem to be one of America's most accomplished Goethe scholars.The volume consists of fifteen essays by prominent scholars and is divided into three parts. The first part, "The Ghosts of Goethe's Past," deals with the effects of scientific advances on Goethe's work (Andrew Piper); the influence of the Gothic on his perceptual experience of architecture (Clark Muenzer); the case of doubles in Wilhelm Meisters Lehrjahre and Faust (Helmut Ammerlahn); and what Goethe accomplished while experiencing "sacred vocal music in the intimacy of his home" (Meredith Lee). The second part, "The Ghost That Keeps on Giving," draws attention to the fictional ghosts found in Goethe's works, with a heavy focus on Faust I and Faust II {Dieter Borchmeyer, Richard T. Gray, Robert Deam Tobin, and Peter J. Schwartz). Patricia Anne Simpson engages more closely with Brown's theory of allegory by looking at the figure of Gretchen in Adorno's readings and citations of Goethe's female figures. In the third section, "Spirited Encounters," the focal point shifts to other authors who wrote in the wake of Goethe. Two contributions engage with Hegel: Franz-Josef Deiters reads Hegel's "effacement" of the "poetic origin of history" (240), while David E. Wellbery shows how Hegel and his notion of freedom "achieve a cognate poetic articulation in Goethe's fragmentary Festspiel" (217). Further essays, however, discuss writers at a greater temporal distance from Goethe: Martha B. …
