Timing skew mismatch in time-interleaved analog-to-digital converters (TIADCs) greatly degrade the dynamic performance of the TIADC, which can be improved effectively by digital estimation and correction techniques. In this paper, a simple and efficient timing skew estimation technique for M- channel time-interleaved analogue-to-digital converters is proposed. Based on digital mixing and inverse trigonometric calculation, timing skew mismatch can be extracted at one time by injecting a known test sinusoidal signal. Compared with the previous foreground techniques, the proposed technique has a higher computational efficiency and looser limitations. Simulation results show that, for a four-channel 12-bit TIADC model, with $f_{in}/f_{s}=0.41$, signal to noise and distortion ratio (SNDR) and spurious free dynamic range (SFDR) are improved from 24.1dB and 27.4dB to 74.0dB and 106.8dB, respectively.


Abstract Conclusion: Our findings demonstrated that purple bamboo salt (PBS)-pharmaceutical acupuncture has an ameliorative effect on cisplatin-induced ototoxicity. Objectives: We have previously reported that PBS exhibited anti-allergic and anti-inflammatory actions in vitro and in vivo. Pharmaceutical acupuncture is a traditional oriental therapeutic technique that combines acupuncture with herbal treatment. The aim of this study was to investigate the protective effect and mechanism of PBS-pharmaceutical acupuncture against cisplatin-induced ototoxicity in the auditory cell line, HEI-OC1, and in vivo. Methods: The ELISA method, a caspase-3 assay, an MTT assay, Western blot analysis, and a luciferase assay were utilized to investigate the effect of PBS in vivo and in vitro. Results: When it was acupunctured at the Ermen acupoint (triple energizer meridian 21) after an administration of cisplatin, PBS-pharmaceutical acupuncture significantly suppressed interleukin (IL)-6 production and caspase-3 activation induced by cisplatin in the cochlea. In addition, PBS significantly inhibited cisplatin-induced apoptosis and IL-6 production in HEI-OC1 cells. PBS also suppressed cytochrome c release and caspase-3 activation, and it inhibited extracellular signal-related kinase and nuclear factor-κB activation in HEI-OC1 cells.


ACADEMIC FREEDOM for teachers in the public schools may be defined as the freedom of teachers to have primary control over the delivery of instruction, short of employing practices that jeopardize student physical or emotional safety. By this definition, teachers are entitled to promote student examination of issues by exercising their professional judgment when teaching. Still, while educational sociologists from Waller to Lortie describe the classroom as peculiarly the domain of teachers' influence and control, teachers tend to be conservative in their judgment of teaching controversial issues.(1) The nature and quality of academic freedom in public education is a significant interest of teachers as it is central to the act of teaching. It is of particular importance to social studies education where a large body of literature supports the concept of controversial issues as a cornerstone of a social studies teacher's professional responsibility.(2) The fact that social studies deals with controversial issues makes it more vulnerable to threats to academic freedom than any other subject.(3) Although the right to teach, to inquire, and to study is fundamental to a democratic society, academic freedom is not one of the enumerated rights of the First Amendment of the Constitution. That speaks to some questions about its legal status, but does not deny its moral and professional status. So how much freedom does a public school teacher have to deliver instruction in the classroom? Take the following short quiz to test your understanding of a teacher's academic freedom to exercise professional judgment in examining controversial issues and using controversial materials and methods in the classroom. The Situations Directions: Using the five possible outcomes listed below, respond to each of the situations twice by placing the number of your response on the line provided. First, respond on the basis of how you perceive a school district would act, and second, respond on the basis of how you perceive a school district should act, in each situation. In each situation, place yourself in the role of the teacher and assume that you are tenured. The response choices are 1. You are suspended and formal charges are filed. 2. You have a formal written reprimand placed in your personal file. 3. You receive a verbal reprimand and a caution that you will be carefully observed in the future. 4. You receive suggestions from the administrator relating to the situation. 5. Your conduct is acceptable and no action is taken. Situation One: As a high school teacher in charge of an advanced acting class, you select a play for four students to perform in an annual statewide competition. The play depicts a family that includes a divorced mother, a lesbian daughter, and a daughter pregnant out of wedlock. You notify the principal of the play you have chosen and get parental permission for the four actresses to perform in the play. Prior to the state finals competition, a scene from the play is performed before an English class in your school. You inform the English teacher that the play contains mature subject matter and suggest that the students bring in parental permission slips to see the play. Following that performance, a parent of one of the students in the English class complains to the school principal. Response Number HOW would the school act in this situation? How should the school act in this situation? Situation Two: As a high school teacher teaching logic and debate to 17- and 18-year-old seniors, you show a film rated "R" by the Motion Picture Association to your class without notifying the principal. The characters in the film use profanity and some scenes contain violence and nudity. You preview 15 to 20 minutes of the film with the students, ask them if they want to proceed with viewing the film, and offer alternate assignments in the library for anyone who is disturbed by the film's graphic realism. …


In this paper, a kPRPS-kPRPS scheduling algorithm based on port trunking CICQ switch is proposed, which can solve the network congestion. The scheme not only guarantee bandwidth for a data flow, but also upper delay bound and minimal required crosspoint buffer size.


The tremendous progress of the kinetic consistent schemes in solution of the gas dynamic problems and development of the effective parallel algorithms for the modern high performance parallel computing systems leads the tendency to development of advanced methods for solution of the MHD problems for critical areas of today and future. The novel method proposed to extend the Boltzmann like distribution function with implementation of electromagnetic terms as complex distribution function. This gives powerful tools for the solution of the MHD system of equation in frame of kinetic consistent schemes with common approach for the electromagnetic and gas dynamic processes. The numerical algorithm is based on the explicit scheme, considered preferable for the new generation of the high performance parallel computing systems. It is explained by the logical simplicity and efficiency the algorithms and possibility of easy adaptation to the modern high performance parallel computer systems, including hybrid computing systems with graphic processors. However, the stability conditions are the price to be paid for algorithmic simplicity of the explicit schemes. The detailed space discretisation, from physics point of view and accuracy could require an inordinately small time steps to perform the simulation. The present study propose the extend method of stabilisation of explicit scheme by introducing the hyperbolic terms of MHD equations in particular the second order derivative in time with the regularization parameter which chosen from physics point of. The original physically founded approach gives the significant improvement in the stability condition for explicit schemes. The results of numerical modelling of a set of gas dynamic and confinement of the expanding ionized gas in strong magnetic field are discussed.

Figure 1, top panel, shows that 48 h treatment of human adipocytes with 1 nM 1 ,25-(OH)2-D3 caused a 40% decrease in UCP2 mRNA (P 0.003) whereas direct stimulation of Ca influx with 10 mM KCl, a cell membrane depolarization agent, exerted no effect. Similar results were observed on UCP2 protein levels measured by Western blot (P 0.002, Fig. 1, bottom panel). 10 nM isoproterenol caused a twofold increase in adipocyte UCP2 mRNA (P 0.002), which was completely blocked by 1 ,25-(OH)2-D3 but by only 20% by KCl. Although KCl inhibited isoproterenol-stimulated increases in UCP2 protein (P 0.006), 1 ,25(OH)2-D3 exerted a more potent effect, reducing UCP2 protein below basal levels. Free fatty acids (oleic acid, linoleic acid, and stearic acid mixture) caused a twofold increase in UCP2 mRNA that was completely prevented by 1 ,25-(OH)2-D3, but not by KCl. These data indicate that 1 ,25-(OH)2-D3 inhibition of UCP2 expression is largely independent of its effects on Ca influx or fatty acid flux.

The time evolution of chemical instabilities and the appearance of "Dissipative Structures" are investigated in detail for a model. It is shown that the nature of the initial fluctuation is crucial in the early stages of the instability, and determines completely the evolution towards organized states. It is also concluded that such states once formed can be surprisingly stable.


This study focuses and critically analyses the contribution of micro-teaching on teacher development of teaching skills through a micro-teaching programme. Microteaching frequently takes place as a group activity and entails planning and instructing a brief lesson or portion of a lesson to a group of other pre-teachers. This is followed by feedback from the teacher trainer and the peers. Since micro teaching across the globe have long discussed and acknowledged the advantages of this educational strategy, most pre-service Teacher Education programmes now incorporate it as a core component. The study was based on Interpretative Phenomenological Analysis principles (IPA) with thematic analysis. Six pre-service teachers were interviewed. Three themes emerged from these interviews, namely, a micro teaching programme, a practical teaching component, and a mentor teacher. The findings showed that the absence of a microteaching programme affected pre-service teachers' overall training. It is recommended that in future, technology should be explored that could facilitate a microteaching programme. This will enhance the quality of microteaching and enable the accommodation of pre-service teachers during a time of crisis, as experienced with the Covid-19 pandemic. In addition, institutions should begin to exploit technology in future. In conclusion, teachers who went through the crisis must be identified and assisted to reach their full potential.

Abstract The question "What is consciousness for?" is considered with particular relevance to objects created using interactive technologies. It is argued that an understanding of artificial life with it attendant notion of robotic consciousness is not separable from an understanding of human consciousness. The positions of Daniel Dennett and John Searle are compared. Dennett believes that by understanding the process of evolutionary design we can work towards an understanding of consciousness. Searle's view is that in most cases mental attributes such as consciousness are either dispositional or are observer relative. This opposition is taken as the basis for a discussion of the purposes of consciousness in general and how these might be manifest in human and robotic forms of life.


Introduction . Spinal canal tumors are divided into intradural or extradural. Depending on the location, their symptoms differ and the prognosis depends on many variables. The magnetic resonance imaging (MRI) is used as a diagnostic tool facilitating diagnosis of proliferative lesions of the spinal canal, and the surgical treatment is most commonly used treatment for tumors located in the spinal canal. Case Report . A 58 year-old patient diagnosed with Intradural extramedullary schwannoma located on the left side of the spinal canal at the L3 level was admitted to the Neurosurgery Clinic based on a referral for surgical treatment. Before surgery, the patient complained about pain in the lumbar region radiating to the lower limbs, feeling of numbness and tingling of the lower left limb for about 2 months and recurring constipation. Discussion . Patient care after surgery on the spinal cord must be comprehensive. Nursing and therapeutic care should be adopted to the individual needs of the patient following the recommendations. Conclusions . The case of the patient after surgical removal of the spinal canal tumor indicated the difficulties the patient struggled with. Main nursing care activities provided the patient with assistance in meeting his physiological needs, performing daily activities and helping to return to good physical condition. The acquired knowledge contributed to improving the daily functioning and coping with difficult situations. All the actions taken in this field brought the intended effect.

Five geographic strains of Aedes albopictus from Japan and Southeast Asia and three strains of Aedes aegypti from Indonesia and Pakistan were compared for their susceptibility to oral infection with the human virus, dengue-1 Mochizuki strain (isolated in 1943, Japan) and A88 strain (isolated in 1988, Indonesia). Female mosquitoes, aged 3-4 days, were infected with a virus-erythrocyte-sucrose suspension. After 14 days of incubation at 25-30°C, viral infection in mesenteron (midgut) or in head-thorax (salivary gland) of each individual mosquito was identified by the reverse transcriptase-polymerase chain reaction (RT-PCR) amplification of dengue-1 virus envelope gene. Although the results of susceptibility varied in some extent in different strains of mosquitoes and viral strains, the oral susceptibility to both dengue-1 virus strains was not significantly different among dengue vector mosquitoes from Japan and Southeast Asia.


Phase identification is important for the safe operation of distributed power grid, and a data-driven phase identification approach has been proposed in this paper, in which the OpenDSS (Open distribution system simulator) is used to perform power flow analysis on a real distribution feeder-European Low Voltage Test Feeder. The spectral clustering is used to identify phases of users/smart meters. Verification by European Low Voltage Test Feeder in different settings. The phase identification accuracy of proposed method is over 95% when the voltage sampling period is no more than 1 hour in the case of complete data set. Results indicate that the proposed method performs better than the constrained k-means method when the sampling period exceeds 15 minutes.


The goal of the Spring 1990 EGM 4001 Design class was to design, fabricate, and test sensors and control systems for a closed loop life support system (CLLSS). The designs investigated were to contribute to the development of NASA's Controlled Ecological Life Support System (CELSS) at Kennedy Space Center (KSC). Designs included a seed moisture content sensor, a porous medium wetness sensor, a plant health sensor, and a neural network control system. The seed group focused on the design and implementation of a sensor that could detect the moisture content of a seed batch. The porous medium wetness group concentrated on the development of a sensor to monitor the amount of nutrient solution within a porous plate incorporating either infrared reflectance or thermal conductance properties. The plant health group examined the possibility of remotely monitoring the health of the plants within the Biomass Production Chamber (BPC) using infrared reflectance properties. Finally, the neural network group concentrated on the ability to use parallel processing in order to control a robot arm and analyze the data from the health sensor to detect regions of a plant.


In 1981, a double burial from the 9th century was excavated at Gerdrup, north of Roskilde. The grave contained remains of the bodies of a woman and a man. The woman was buried with a spear, whilst the man had apparently been killed before burial. This has been interpreted as a 'master and slave burial', which was placed at an isolated location, perhaps because the buried were regarded as pariahs. However, previously unpublished excavation data combined with new 14C analyses indicate that the burial was part of a small multi-period burial site, which was located near a group of earlier burial mounds. Topographic analyses show that the burial was also located on an important ford, and therefore had a prominent location. Significantly, new DNA analyses surprisingly indicate that the two buried individuals actually have a parent-offspring relationship: they are mother and son. The previous interpretation of the Gerdrup grave is thus challenged. This article will present the relevant excavation data and discuss this in the light of the new analyses.

The exponentially increasing amount of data in file systems has made it increasingly important for file systems to provide fast file-search services. The quality of the file-search services is significantly affected by the file-index overhead, the file-search responsiveness and the accuracy of search results. Unfortunately, the existing file-search solutions either are so poorly scalable that their performance degrades unacceptably when the systems scale up, or incur so much crawling delays that they produce acceptably inaccurate results. We believe that the time is ripe for the re-designing of a searchable file system capable of accurate and scalable system-level file search. The main challenge facing the design and implementation of such a searchable file system is how to update file indices in a real-time and scalable way to obtain accurate file-search results. Thus we propose a lightweight and scalable metadata organization, Propeller, for the envisioned searchable file system. Propeller partitions the namespace according to file-access patterns, which exposes massive parallelism for the emerging manycore architecture to support future searchable file systems. The extensive evaluation results of our Propeller prototype show that it achieves significantly better file-indexing and file-search performance (up to 250×) than a centralized solution (MySQL) and only incurs negligible overhead (< 16%) to the normal file I/O operations and faster direct access performance (16.6×) on a state-ofthe-art file system (Ext4). Furthermore, the 100% recall accuracy ensures Propeller offering a feasible metadata scheme for the system-level file-search services.


Background: Due to increases in climate change, deforestation, and human population, viral pandemics are predicted to become more frequent.1 Key technological advances in testing are needed to limit the impact of pandemics on human mortality and global economies. Testing for active infection allows early identification of carriers, both symptomatic and asymptomatic, isolation of affected areas, thus limiting spread. From an individual health care perspective, testing allows differentiation of the pandemic disease from diseases with related symptoms to guide proper treatment regimens. Broad and efficient testing would also allow community activities to continue in a safer environment and avoid the negative consequences of job loss, risk of exposure to infected coworkers while on the job, reduced educational opportunities, and social isolation.

Abstract Eduard Steichen (1879-1973) met the Belgian Symbolist writer Maurice Maeterlinck in 1901, when Steichen was in Europe. Steichen's goal there was to photograph painters and writers whom he personally admired,1 including Maeterlinck whom Steichen photographed in 1901. Maeterlinck attended Steichen's first one-man exhibition at Maison des Artistes in 1902 and looked favourably on the young artist's work. Maeterlinck and Steichen discussed photography at the time. Steichen thought that Maeterlinck's comments were 'more considered than any [he] had heard before' and 'wondered whether he would put down some of his thoughts'2 to be included with reproductions of Steichen's photographs in Camera Work. Steichen felt emphatically that his best photographs should be reproduced with Maeterlinck's statement, and he told Alfred Stieglitz as much.3 The connection between Maeterlinck and Steichen has not gone unnoticed

Increasing numbers of perinatally HIV-infected children are surviving into their teens and beyond. Research and clinical reports suggest that many HIV-infected children, particularly those younger than 13 years, do not know they are HIV infected owing to parental concerns about the impact on their mental health. This study examines patterns of HIV status disclosure to 77 perinatally HIV-infected ethnic minority children (aged 3–13 years), and explores the association between knowledge of HIV status and emotional and behavioral outcomes. The majority of children in this study (70%) did not know their HIV status. On average, children who knew their HIV status were older and tended to have lower CD4%. Child knowledge of HIV status was not associated with gender, ethnicity, caregiver education, parent–child relationship factors, type of placement (biological vs adoptive), or other health status indicators. As hypothesized, HIV status disclosure to infected children did not result in increased mental health problems. There was a statistical trend for children who knew their HIV status to be less depressed than children who did not know. Also, greater social disclosure (e.g. communication of child's status to family and friends) was found when the child had an AIDS diagnosis or lower CD4%, as well as when the caregiver was HIV negative, African American and not the child's biological parent. In conclusion, pediatric HIV infection remains a highly stigmatized issue that is difficult to discuss with the infected child and others. Yet, contrary to the beliefs of many caregivers, disclosure did not result in increased mental health problems.

1 This paper discusses the potential for improved detectors in Positron Emission Tomography (PET) and explores the ultimate limits that might be achieved in the areas of spatial resolution, sensitivity, and maximum imaging rates. It is shown that if an ultra-fast, high· efficiency scintillator and a thin, low-noise, positionsensitive photodetector were available, a multi-layer time-of-flight tomograph would be possible with a 10 em axial field of view, a 3-dimensional spatial resolution of 2 mm fwhm,.and >700,000 prompt unscattered coincidences per sec for 1 JLCi per cm in a 20 em diam cylinder of water. 1 IM:PROVED DETECTORS 1.1 SCINTILLATION CRYSTALS Table 1 lists properties of three detector materials commonly used in positron tomographs, Nai(Tl), BaF2 , and bismuth germanate (BGO). Nai(Tl) has the best photon yield and pulse height resolution, BaF2 has the best timing resolution, and BGO has the best detection efficiency. An "ideal detector" with the best properties of all three has not yet been found. However, the scintillation properties of three important heavy inorganic crystals have been discovered rather recently: BaF 2 in 1971 (1), BGO in 1973 (2), the fast component of BaF2 in 1982 (3,4), and GSO in 1982 (5). Further efforts in this direction are essential if the potentials of PET are to be fully realized. TABLE 1.

For example, there is only a 5% probability that an incident 511 keY photon will deposit all its energy in a 5 mm x 5 mm x 30 mm deep germanium crystal (8). The detection efficiency can be significantly improved (to over 50%) by using a low pulse height threshold, but the efficiency is still well below that of the heavy element scintillators. Both Hgl2 and CdTe have good detection efficiency due to their high atomic numbers and densities but have not yet been developed to the point where thousands of detectors can be used in large tomographs. The development of such heavy element semiconductors (9,10), would provide an attractive alternative to the scintillator. detector by eliminating the photomultiplier coupling problem and by providing better pulse height resolution than scintillation detectors. r,

Abstract. Vascular endothelial cells (VECs) are able to induce HIV1 replication in СD4 + Tcells, thus deter mining their resistance for apoptosis. The revealed facts are specific to EC/Tcell culture and are stipulated by the cellcell interactions between the VECs and HIV1 producing cells, thus being a consequence of activation of 'productively infected' T cells.


More refined heat control is usually obtained with a resistance-heating system, and its low inertia permits rapid changes in temperature that might be required by the process or production rates. Temperature is easily controlled to prevent hot spots that can damage the product or the heat-transfer fluid. With resistance heating, ovens and kilns for continuous in-line processes can easily be controlled for applications in which the temperature of the product must be raised or lowered gradually as the product passes through. Electric resistance heating has been the most economical means of supplying process heat in many applications. Energy-source economics has greatly extended the range of applications in which electric heating competes favorably with fossil-fuel-fired heating equipment. Resistance heating will continue to gain in advantage as industry moves toward an essentially all-electric economy. It should be evaluated as an alternative to fossil-fuel firing in any process-heating application that has traditionally been met by oil or natural gas.


Colonialism as a political, historical, economic and literary concept is generally negatively perceived and portrayed in all ramifications. This perception and depiction is not unconnected with its historical and cultural denigration, oppression suppression, economic exploitation and deprivation, literary prejudice and linguistic interference in the former colonies. However, a critical and dispassionate study of some Anglophone African novels reveal that colonialism, in spite of its derogatory perceptions and criticisms by many African intellectuals from all walks of life, possesses some redeeming features and incontrovertible landmark achievements that made it a necessary evil. This study, therefore, highlights the implied and obvious opinions of some notable African novelists, who through their novels, acknowledged that Colonialism was a negative instrument that advertently or inadvertently brought enlightenment, progress and divergent developments to the colonized Africa and her people. In fact, the study shows that Colonialism was a positive evil and a blessing in disguise to Africa and Africans.


In this note we extend the concept height on projective spaces to that of weighted height on weighted projective spaces and show how such a height can be computed. We prove some of the basic properties of the weighted height and show how it can be used to study hyperelliptic curves over Q. Some examples are provided from the weighted moduli space of binary sextics and octavics.


This paper presents a hardware efficient high definition television (HDTV) encoder for H.264/AVC. We use a two-level mode decision (MD) mechanism to reduce the complexity and maintain the performance, and design a sharable architecture for normal mode fractional motion estimation (NFME), special mode fractional motion estimation (SFME), and luma motion compensation (LMC), to decrease the hardware cost. Based on these technologies, we adopt a four-stage macro-block pipeline scheme using an efficient memory management strategy for the system, which greatly reduces on-chip memory and bandwidth requirements. The proposed encoder uses about 1126k gates with an average Bjontegaard-Delta peak signal-to-noise ratio (BD-PSNR) decrease of 0.5 dB, compared with JM15.0. It can fully satisfy the real-time video encoding for 1080p@30 frames/s of H.264/AVC high profile.


On the strength of such influential books as Death of Nature (1980), Ecological Revolutions (1989), Earthcare (1996), and others, and as past president of the American Society for Environmental History, Carolyn Merchant is rightfully recognized as one of the pre-eminent environmental historians in the United States.[1] Furthermore, Merchant has been exceptionally committed to educating students and non-academics in environmental history. For example, by compiling and editing the articles and documents found in Major Problems in American Environmental History (1993) and Green Versus Gold she showed her commitment to undergraduate teaching in the field.[2] The Columbia Guide to American Environmental History fits in the same category. It is designed to be "a concise 'first-stop' reference book on the history of the North American environment for high school and college students, teachers, researchers, and readers" (p. xviii).[3] Unfortunately, the book does not realize its full potential.


Using a commercially available software package, overlay sample plans were evaluated for use in a 0.5 micrometers manufacturing process. Monitor wafers were patterned using a two layer overlay evaluation reticle set. Known values of both grid and field errors were entered into the stepper during the exposure of the second layer to force a controlled range of misregistration. Extensive overlay measurements were collected from these wafers. These detailed data sets were modeled to define the relationships between distortion coefficients reported by the software and those actually entered into the stepper. Using the modeled distortions obtained from the original data set as the `correct' values of overlay distortion present on the die/wafers, it was possible to model subsets of the original data set to determine the most efficient sample plans for manufacturing. The accuracy and uncertainty of the modeled overlay distortions was found to be dependent on the sample plan, both in terms of the number and location of measurements taken.


In their zeal to discredit Carl Schmitt because of his political beliefs scholars often overlook the fact that Schmitt was both a highly regarded constitutional scholar and a brilliant legal theorist. Lars Vinx's volume clearly reveals that Schmitt was ranked high among the constitutional theorists in Germany during the late 1920s and early 1930s and Volker Neumann's book convincingly demonstrates that Schmitt was one of Germany's most impressive legal thinkers of the twentieth century. The first book argues that Carl Schmitt ranks alongside such legal scholars as Gerhard Anschütz, Hermann Heller, Erich Kaufmann, Rudolf Smend, and Richard Thoma and the second demonstrates that Schmitt was the equal to Hans Kelsen. While Kelsen is Schmitt's main antagonist in Vinx's book, he figures prominently in Neumann's as well; accordingly, Hans Kelsen is a major presence in both books. In Vinx's introductory and explanatory material as well as in Neumann's entire book, Carl Schmitt is shown to be a serious and thoughtful legal thinker. As a result, the reader receives a full and factual account of Schmitt's legal thought, free from personal polemics and from political diatribes. Anyone wishing to understand Carl Schmitt's opinions regarding the Weimar Constitution and wanting to comprehend his legal thinking should read these two books. Anyone hoping to find denunciations of Schmitt's political opinions and criticisms regarding his Nazi leanings should look elsewhere. chRistopheR AdAiR-toteff University of South Florida

Data are presented indicating that the major pathway for the oxidation of naphthalene by a strain of Pseudomonas occurs via salicylic acid, which is further oxidized through catechol to β-ketoadipic acid. On the basis of growth, simultaneous adaptation, and cell-free extract experiments, the following compounds are regarded as unlikely intermediates in naphthalene dissimilation: 1,4-naphthoquinone, α-naphthol, β-naphthol, 1,3-dihydroxynaphthalene, 2,3-dihydroxynaphthalene, 1,5-dihydroxynaphthaIene, phenol, trans-o-hydroxycinnamic acid, and phthalic acid. Evidence was found that a second pathway of naphthalene oxidation produces 1,2-naphthoquinone. 1,2-Dihydroxynaphthalene was found to be non-enzymatically converted to 1,2-naphthoquinone. The 1,2-naphthoquinone was not further metabolized and was found to be responsible for the characteristic brown to reddish orange color of the culture medium. Omission of FeCl2 and MgSO4 from the basal medium prevented the formation of salicylic acid but did not interfere...

The main aim of this research was to asses the practice of traditional birth attendant towards prevention of mother to child transmission of HIV/AIDS (PMTCT) in Calabar South Local Government Area. Four specific objectives were formulated to asses the level of knowledge and practice of traditional birth attendants towards the prevention of transmission of HIV/AIDS from mother to child during pregnancy and puerperium. A descriptive study was adopted to gather already existing information. The result of the analysis shows that 150 traditional birth attendants (TBAs) selected from 6 wards have knowledge about HIV/AIDS though not adequately geared towards the prevention of transmission of HIV/AIDS from mother to child, and also demonstrate poor practice toward PMTCT. It was recommended that traditional birth attendants should be given appropriate and adequate training on PMTCT and timely monitoring and evaluation of their practice.


Background : Varicocele is a dilated vein of the pampiniform plexus that cause to detrimental time-dependent effects so this study describes the effect of varicocele on the level of IL-6 and interferon gamma in serum and testis tissue, number of sertoli and spermatogonia cells, seminiferous tubules diameter and sperm activity in immature rats. Methods : Thirty six immature rats, 5-6 weeks aged were investigated in this study. The sham groups underwent sham operation and varicocele groups underwent partial ligation of the renal vein. Serum, testis and sperm samples were collected at 9, 11, and 13 weeks after induction of varicocele or sham operation to evaluate histological parameters (seminiferous tubules diameter, number of sertoli and spermatogonia cells), per-centage of sperm motility and viability and levels of cytokines. Testicular morphology was evaluated. Results : Varicocele significantly caused an increase in serum and testis IL-6 and interferon gamma, compared to related sham groups and previous varicocele groups (P<0.05). Varicocele significantly caused decreases in sertoli cells and spermatogonia cells number with increasing varicocele time, compared to related sham groups and previous varicocele groups (P<0.05). In the evaluation of seminiferous tubules diameter external, internal and epithelium diameter were decreased compared to sham related groups and previous varicocele groups. In all varicocele groups, all kind of sperm motility and viability decreased compared to the related sham-operated groups (P<0.05). Varicocele had deteriorating effects on testis tissue because our observations in varicocele groups demonstrated that the external, internal and germinal epithelium height was reduced by the time and in the evaluation of testicular cells, sertoli and spermatogonia cells number were decreased by the time compared to sham related groups and previous varicocele groups. Conclusion: This study suggests varicocele had a detrimental time-dependent effect on cytokines levels and decrease in sertoli and spermatogonia cells number, seminiferous tubules diameter and sperm indices.

Chairman McTaggart-Cowan, President Malone, Members of the American Meteorological Society, guests, and fellow scientists: the subject on which I speak is not the most important subject in the world today. To you and to me and, I believe, to thoughtful people throughout the world the most important subject is—in the inaugural words of President Kennedy—". . . the quest for peace, before the dark powers of destruction unleashed by science engulf all humanity in planned or accidental self-destruction." Unleashed by science: those are stark words. They strike close to home. We can ignore them neither as scientists nor as citizens. We must respond. But our response must be calm and rational and constructive. Our responding will challenge to the utmost our intellectual powers and our ethical perceptiveness. We must understand, with precision and clarity, the relationship between science and the destruction it has unleashed. We must discern, with integrity and responsibility, the difference between scientific facts and value judgments. There is, of course, another aspect to the threatening cloud of destruction, and this aspect, also, was put forth by Mr. Kennedy when he said: "Let both sides seek to invoke the wonders of science instead of its terrors. Together let us explore the stars, conquer the deserts, eradicate disease, tap the ocean depths and encourage the arts and commerce." The wonders of science: those are words of hope. We welcome them and we feel impelled to rush forth with good works. But here, too, our response must be balanced and thoughtful. We must discriminate between the discovery of new knowledge and the utilization of that knowledge for practical ends: between science and technology. Both are essential and both are im-


This paper is based on the author's concerted experience in Indian and multi-national corporations. Having worked extensively in areas of change management, this paper simplifi es the ever-changing dynamics of communication. The author also lays emphasis on the misconceptions pertaining to technology-based communication which most big organizations subscribe to. It is often perceived that communication becomes easier because of the use of technology. The same is debated in the paper in detail. It should be understood that communication is a two-way process. Stressing on precise and transparent communication, the paper directs the intent of the research query to a more value-based communication. Moving ahead, this can prevent sprouting of rumors in the organization if carried out effectively. Effective communication is the sole carrier of a fruitful work culture and the advent of technology can facilitate it. T skill to communicate has always been vital for individuals. It is what every human being learns, implicitly and explicitly, from the time they enter this world. It sets the successful apart from the rest. Today, it has gone on to becoming an organisational skill, differentiating successful organisations from the others. But how does something as simple, omnipresent and innocuous as communication cause the downfall of entire organisations? "The s ingle biggest problem in communication is the illusion that it has taken place." (George Bernard Shaw) With the current age of technology and communication media, one might imagine that businesses would have no problem in forming and maintaining lines of communication with their employees. It goes without saying that an organisation's employees are spokespeople for that organisation. They convey a picture

Focused microwave breast hyperthermia (FMBH) represents a newly emerging technique endowed with advantages of high accuracy and low side effect for treating breast tumors. Practical application of the FMBH approach requires monitoring of microwave power deposition in the breast. Microwave-induced thermoacoustic imaging (MITAI) is naturally feasible for such power deposition monitoring task. This work conducts a computational study to evaluate feasibility of the novel FMBH-MITAI modality using realistic breast phantoms. Basic configuration and rationale of both FMBH and MITAI are introduced. Compressive sensing (CS) technique has to be applied in MITAI for sparse acoustic measurement in the FMBH-MITAI modality. Procedure of the computational study consists of microwave simulation, thermoacoustic numerical simulation, CS imaging, and performing the iterative optimization. Simulated results show that CS based MITAI is able to serve as a reliable monitoring mechanism to efficiently guide the iterative optimization toward the best obtainable focusing condition in most of the simulated scenarios. Finally obtained thermoacoustic images agree well with simulated power deposition distribution well. This work offers valuable performance evaluation and is of significant meaning for potential clinical applications of the FMBH-MITAI modality.


Abstract : A breadboard model Electron Beam Recorder on SiO2 storage targets was fabricated and evaluated under this program. The breadboard device in a drum configuration was used to make measurements of the frequency response of the electron gun and the electron beam in both read and write modes of operation. After completion of these measurements, the drum containing seven storage targets was installed and measurements of storage medium reciprocity and output signal to noise ratio (SNR) were made.

A Fabry-Perot open resonator (FPOR) is a tool dedicated to broadband accurate microwave and millimeter-wave characterization of dielectric sheets. Despite the various advantages of that method, one of the major challenges limiting its applicability is unintentional coupling of Gaussian modes of interest with a particular family of parasitic higher order modes. The coupling affects the resonance frequency of the resonator loaded with the material under test, thus disturbing the extracted permittivity. It has already been shown that spectral properties of these parasitic modes can be predicted using a recently developed electromagnetic model of a FPOR based on the scattering matrix method. It is shown in this article that the systematic analysis of experimental results supplemented with accurate numerical computations allows us to suppress the impact of mode coupling on the measured permittivity.


Recent investigations of the history of social psy chology demonstrate that the internal development of theory, methods and research cannot be separated from the social con text in which they occur. Instead, these developments reflect a dialectical exchange between science and society. The present paper reviews recent studies of social psychology's historical development; points out the inadequacies of traditional views of our history as a progression from metaphysical speculation to scientific experimentation; and discusses the implications of critical history for our "current crisis."


It is shown that the correct interpretation of standardized multi-factor models requires the calculation of corrections to the regression equations and depends on the statistical characteristics of input data The forms of the corrections are got and accuracy of them is evaluated.


It has been revealed that available phosphorus determined on responses of the toe ash content of chicks1) is useful criterion to indicate dietary level of phosphorus which is available particularly for the bone formation of chicks. It was reported2-4) that a diet containng minimum levels of calcium and phosphorus to support optimum growth of chicks resulted in poor calcification of the bone. Significant breed difference was also reported3) on the response of the toe ash content between the egg-type and meat-type chicks fed a diet of the same composition. Since the determination of the toe ash content is very simple and timeand labour-saving, the content has been used in these experiments mentioned above as a criterion to indicate the bone hardness and the bone ash content. Linear relationship between the toe ash content and the tibia bone hardness was already reported in the previous papers5).In this paper, breed difference in linear relationship between ash contents of the toe and the tibia bone was reported.


Electroforming replication technology at Marshall Space Flight Center has a long heritage of producing high-quality full-shell x-ray mirrors for various applications. Nickel alloys are electroformed onto a super-polished mandrel in the electroforming process, then separated to form the replicated full-shell optic. Various parameters in the electroplating configuration could result in the nonuniformity of the shell's thickness. Thickness non-uniformities primarily occur due to non-uniform electric field distributions in the electroforming tank during the deposition. Using COMSOL Multiphysics simulations, we have studied the electric field distributions during the deposition process. Using these studies, we have optimized the electric fields inside the tank using customized shields and insulating gaskets on the mandrel. These efforts reduced thickness non-uniformity from over 20% to under 5% percent. Improving the thickness uniformity of the shell aids in better mounting and alignment of shells in the optics module. Optimization of the electroforming process, in some cases, improved the optical performance of the shells. COMSOL optimizing of the electroforming process and the experimental results validating these simulations are presented in this article.


This report emerges from the curricular unit of Supervised Teaching Practice II and results in the description of two pedagogical interventions, as well as in the presentation of a study. The interventions took place in a 2 grade class of the 1 Cycle of Basic Education and in two classes of 6 grade of the 2 Cycle of Basic Education. The study carried out in the 2 Cycle of Basic Education with the purpose to characterize the written communication in Mathematics of two classes of 6 grade. Therefore, the present study tried to answer three questions: (1) how is characterized the written communication in Mathematics of two classes of the 6 grade with regard to the correction? (2) how is characterized the written communication in Mathematics of two classes of the 6 grade with regard to the clarity?; (3) how is characterized the written communication in Mathematics of two classes of the 6 grade with regard to the argumentation? Since the interpretive paradigm was associated to the main purpose of the study, qualitative methodology appeared to be more appropriate. The data were obtained through a documental collection, which included the resolutions of thirty-four students to four mathematical tasks performed in class. These mathematical resolutions were the object of a documental analysis, in order to qualify the correctness, clarity and argumentation. Frequency calculations were also used to quantify the data collected, in order to respond to the questions already mentioned. Based on the results, it was possible to conclude that the students evidenced a positive performance in their written communication in Mathematics, namely for appealing to arguments throughout their resolutions. Among the dimensions correction and clarity, it was in the first one that the students exhibited a better performance. Key-word: Written communication in Mathematics; Correction; Clarity; Argumentation


This study evaluates a regional full employment initiative using the synthetic control method introduced by Abadie and Gardeazabal (2003). The aim of the Paltamo Full Employment (PFE) experiment launched in 2009 is to reverse the trend of high and persistent unemployment in contracting regions. The basic idea behind the experiment is to collect all unemployment related expenditures together and use them in employing all unemployed persons. According to our results, the PFE-experiment has managed to lower the unemployment rate in Paltamo by almost 10 percentage points in just two years time during an era of global financial crisis. The costs of this remarkable drop in unemployment were 3.4 million Euros in 2010. The results show that one fifth of this amount is covered by reduced expenditures on unemployment allowances and housing allowances.


There is a need to develop more effective strategies for improving usability within information and

communication technologies, specifically, electronic health record (EHR) systems. Usability incorporates

the ease of use, learnability, efficiency, effectiveness and satisfaction of a system by the end user. When an

EHR incorporates principles of usability, the system does a better job of meeting the needs of the end users

intuitively, resulting in fewer errors and better quality outcomes for patients. Health systems and

governments have been urging the widespread adoption of EHR systems to help lower costs and increase

efficiency, putting themselves and vendors under pressure to develop and implement the best solution

quickly. Too often stakeholders rely on future releases and enhancements to fix issues not originally

planned for in the initial release of the product. Hospital system end users and vendors need better strategies

for improving usability in EHR solutions. Poor usability can result in frustrated end-users, inefficient and

more costly processes, and, at worst, compromises to patient safety. Proposed strategies and areas for future

development are discussed.


Abstract Using SBA-15 as a template, high surface area porous graphitic carbon nitrides (g-C3N4) were successfully synthesized by pretreating melamine using hydrochloric acid, and fully characterized by Fourier-Transform infrared (FT-IR), X-ray diffraction (XRD), scanning electron micrographs (SEM), N2 adsorption-desorption, ultraviolet-visible (UV-Vis) spectroscopy, photoluminescence (PL) spectrum. The results of these analyses indicated that the g-C3N4 synthesized from HCl-pretreated melamine with SBA-15 as a template has enhanced specific surface area and increased the separation rate of the photogenerated electrons and holes compared with bulk g-C3N4, but didn't change the structure of bulk g-C3N4. The photocatalytic activity of samples was evaluated by the degradation of rhodamine B (RhB) under xenon lamp. The results indicated that the activity was improved significantly with the increase of specific surface area. The rate constant for CN-3(HCl pretreatment melamine precursor and SBA-15 as a template) was 13 times as high as g-C3N4. Furthermore, the CN-3 catalyst exhibited outstanding structural and catalytic stability. GRAPHICAL ABSTRACT

We have developed the New Studio format of instruction for improved conceptual learning while retaining problem-solving skill development in large, first-year physics courses. This format retains the large lecture, but combines traditional recitation and laboratory instruction. The New Studio format integrates simplified laboratories with assigned homework problems to integrate conceptual and problem-solving skills. The studio format combines 2hours of lecture with 4hours of studio each week. The studio is taught for 2hours twice per week, and consists of up to 40 students working in groups of four at tables equipped with modern instructional technology and apparatus. The group setting allows for peer instruction and development of group skills. The combination of traditional lecture with the studio format enables a research-oriented physics department with a large service teaching load to implement research-based pedagogy. Student gains on the Force Concept Inventory were similar to other courses taught ...


T1HE BRITISH general practitioner visiting another country can be just a tourist or he can use such an opportunity to look at medical services and make useful informative comparisons, helpful in today's concern about a future for family doctors. With the tide of general practice in the National Health Service at low ebb what can be learnt from a brief visit to another country with Comparable Western European culture, and with a similar branching of medical care into hospital and general practice? Against the background in this country of wide variations in individual doctor's performance and in facilities available to him the visit was an opportunity to examine such similar aspects as the general practitioner and his organization and the relationship between him and hospital. This paper describes such a reconnaissance made during one week's visit to Denmark recently and what can be learnt from it.


Abstract This article contains an interpretation of the life stories of political activists who were detained under the internal security measures operative during the various States of Emergency (1985–1989). An attempt is made to reconstruct aspects of these activists' journeys during these times. The focus is not only on the physical movements, but also on the emotional and subjective 'journeys' during this period of turmoil. All the activists who related their life stories mobilized themselves against what they interpreted to be an oppressive political regime. They saw themselves as belonging to a world opposed to that of the regime and separated from it by means of administrative, statutory and even physical boundaries. Their resistance became a real as well as a symbolic expression of their community's opposition against existing structures. Narratives on the activists' involvement in localized outbreaks of rebelliousness form an important part of this article. It is clear that the cumulative effect ...


Educational self‐management programs for children with asthma have now become a routine feature in the management of the disease, as international guidelines underline. We designed this trial to find out whether Aironet®, an educational program developed for children with asthma, influenced asthma severity and improved parents' knowledge of the disease. In a multicenter, prospective, randomized controlled trial we enrolled 123 children, 72 boys, mean age 8.78 yr (±2.33 s.d.), with intermittent or mild persistent asthma. Participants were randomly assigned to an education group, who received Aironet® at baseline and 2 months later (60 children), or to a control group who did not (63 children). Follow‐up lasted 12 months and included out‐patient clinic visits and spirometry at 2, 4 and 12 months. At baseline and at 12 months follow‐up, parents were questioned about their knowledge of asthma, and their children's asthmatic attacks, use of systemic corticosteroids, family physician or hospital emergency room visits, hospitalizations and asthma‐related school absences. Questionnaire replies at 12‐month follow‐up reported significantly fewer asthma attacks in patients who received the program than in those who did not (1.65 ± 1.21 vs. 2.34 ± 1.73; p < 0.05). For the subgroup of children who had ≥3 asthma attacks at baseline, parents' knowledge improved significantly more in the educational group than in the control group. The out‐patient educational program Aironet® reduces the number of asthma attacks in children with intermittent or mild persistent asthma and improves knowledge of the disease.

Abstract Sanjad–Sakati syndrome (SSS), or hypoparathyroidism–mental retardation dysmorphism syndrome, is a rare autosomal recessive congenital disorder characterized by congenital hypoparathyroidism, growth and neurodevelopmental delay, acute symptomatic seizures due to hypocalcemia, and dysmorphic features. The syndrome is underdiagnosed, and neurological manifestations are not previously described. We report three Tunisian patients with SSS revealed by acute symptomatic hypocalcemic epileptic seizures. Despite the well-controlled seizures, patients tend to continue having poor growth and neurological outcome. The diagnosis of SSS allowed for proper treatment of the patients, prevented associated comorbidities, and provided genetic counseling to their families.


The present report describes an unusual physical sign seen in two patients with hepatolenticular degeneration (Wilson's disease). A distinctive blue discoloration of the lunulae of the nails of both hands was present. The blue discoloration was of an azure hue and was restricted to the lunulae.

Congenital disorders encompass a wide range of conditions (e.g. genetic disorders, foetal disease, and developmental disorders) that occur before birth and are an important contributor to mortality and morbidity worldwide. Congenital disorders can be identified at different life stages and effective health services take a holistic approach to their care and prevention. This involves both population health and specialist services across the life course. Systematic collection of data on the types, prevalence, severity, and outcomes of congenital disorders, along with analysis and interpretation of data helps to inform appropriate planning of care and preventative services and activities. Important concepts in relation to congenital disorders, prevention activities, and key challenges to their effective delivery are described in this chapter.

Indicator mineral research is currently being undertaken in partnership with the Nova Scotia Department of Natural Resources and Renewables at the Brazil Lake lithium-cesium-tantalum (LCT) pegmatites in southwest Nova Scotia as part of the Geological Survey of
Canada's Targeted Geoscience Initiative(TGI) program. The pegmatites, discovered in 1960, are well known from previous detailed bedrock mapping and surficial studies, and are informally named based on their relative geographic positions as the South and North pegmatites. The South pegmatite
naturally outcrops, and both pegmatites are surrounded by spodumene-rich boulders on the surface of the thin-till covered (<4 m) drumlinized glacial landscape. For these reasons, the pegmatites are excellent sites to test indicator mineral exploration methods for Li and associated
critical elements (e.g. Ce, Ta). Five pegmatite samples were collected for detailed study and analysis of potential indicator minerals. Close to the pegmatite and up to 13 km down ice (south-southeast), 87 bulk (10-14 kg), till sediment samples were collected for indicator mineral analysis. A total
of 105 till samples were collected around the pegmatite and across the region for matrix geochemistry. A preliminary list of indicator minerals includes mid-density (e.g., spodumene, tourmaline, blue apatite) and high-density mineral species (e.g., columbite-tantalite, cassiterite) and this list is
expected to expand as the detailed studies progress. Trenches dug in the Fall 2022 to collect till samples on the proximal down ice (south) sides of both pegmatites revealed abundant spodumene pebbles and small cobbles in the till, indicating that the local till should display strong indicator
mineral and matrix geochemical signatures derived from the pegmatites.


An analysis has been carried out for the flow and heat transfer of an incompressible laminar and viscous fluid in a rectangular domain bounded by two moving porous walls which enable the fluid to enter or exit during successive expansions or contractions. The basic equations governing the flow are reduced to the ordinary differential equations using Lie-group analysis. Effects of the permeation Reynolds number , porosity , and the dimensionless wall dilation rate on the self-axial velocity are studied both analytically and numerically. The solutions are represented graphically. The analytical procedure is based on double perturbation in the permeation Reynolds number and the wall expansion ratio , whereas the numerical solution is obtained using Runge-Kutta method with shooting technique. Results are correlated and compared for some values of the physical parameters. Lastly, we look at the temperature distribution.


To reduce the risk of transportation planning scheme and improve the whole benefit of project selection in different stages,a multi-stage discrete network design model under stochastic OD demand is set up to determine the optimal project scheduling with stochastic bi-level optimization.The proposed model,a combinatorial optimization problem,is solved using Monte Carlo simulation and genetic algorithm.Numerical results on Nguyen Dupuis network indicate that the distribution of funds has a great impact on decision making and the system performance can be improved with more funds in early days of the whole planning period.Besides,demand uncertainty and planner's preferences are also crucial to the final program.


This letter proposes an analytical method to estimate the frequency of buses of transmission grid based on updated generator speed, internal generator voltages, admittance matrix and bus voltages. The proposed method estimates the buses frequency which are much more reliable, accurate and efficient for transient stability studies in contrast to other existing methods. To demonstrate the efficiency of the proposed approach, the method is applied on IEEE 39 bus test system for frequency support and is compared to other existing methods.


The effects of ligands on clean synthesis of adipic acid via direct oxidation of cyclohexene with 30% H 2O 2 catalyzed by Na 2WO 4·2H 2O were studied. In most cases, the yield of target product adipic acid is high if the acidity of ligand is strong. Although the acidity of some phenolic ligands, L(+)ascorbic acid and 8 quinolinol is weak, the yield of adipic acid is still high. It is demonstrated that the acidic effect and the coordination effect of ligand play the same important role in oxidaton of cyclohexene with 30%H 2O 2 to adipic acid catalyzed by Na 2WO 4·2H 2O. The experimental results for acidic ligand amount and reaction kinetics show that the hydrolysis of cyclohexene oxide to 1,2 cyclohexandiol is a critical step and the acidity of the reaction system is necessary.


This case study focuses on outbreak of COVID-19 in India and world. This will be beneficial to analyze globally rising COVID-19 cases as well as in India in assessment with other 15 countries which have highly suffered due to this pandemic. This analysis will be useful to predict the number of cases at this month end and lockdown days required to combat COVID-19 in India


Investigators commonly gather longitudinal data to assess changes in responses over time and to relate these changes to within‐subject changes in predictors. With rare or expensive outcomes such as uncommon diseases and costly radiologic measurements, outcome‐dependent, and more generally outcome‐related, sampling plans can improve estimation efficiency and reduce cost. Longitudinal follow up of subjects gathered in an initial outcome‐related sample can then be used to study the trajectories of responses over time and to assess the association of changes in predictors within subjects with change in response. In this article, we develop two likelihood‐based approaches for fitting generalized linear mixed models (GLMMs) to longitudinal data from a wide variety of outcome‐related sampling designs. The first is an extension of the semi‐parametric maximum likelihood approach developed in Neuhaus, Scott and Wild (2002, Biometrika 89, 23–37) and Neuhaus, Scott and Wild (2006, Biometrics 62, 488–494) and applies quite generally. The second approach is an adaptation of standard conditional likelihood methods and is limited to random intercept models with a canonical link. Data from a study of attention deficit hyperactivity disorder in children motivates the work and illustrates the findings.


In this reflection the author makes connections between the themes of the special issue and an early series of seminars held at the Freud Museum London, in 1992, 'Psychotherapy Black and White', organized in cooperation with the intercultural therapy centre Nafsiyat. These seminars were invested in the social mission of psychoanalysis, and were intended not only for psychotherapists but for social workers, counsellors, psychiatrists, probation officers, community health workers, teachers and others. The author reflects on psychotherapy as an ecosystem and on the issue of the 'boundaries' of psychoanalysis: when they are excessively policed, this limits the domain of psychoanalytic knowledge, including by undermining the legitimacy of social clinics.


The confluence between a good manager and a good leader stands at the intersection of skills, strategic thinking and ethical integrity specific to the manager and the emotional intelligence, power of persuasion, empathy, passion and open communication specific to the leader. In this context, the present paper's objective is to highlight the interconnection between the management / managers and leadership/leaders.


The tanlock modification of the phase detector characteristics of a phase-lock loop can be used to increase the linear range of operation of the S-curve of an analog loop, hence increasing the tracking and acquisition ranges without increasing the loop gain. The phase-shift-keying tanlock loop is a realization of this modification for the coherent demodulation and tracking of a PSK suppressed carrier signal. In this paper we consider the PSK-TLL loop performance in the presence of additive noise. The equivalent noise source used with the baseband model of the loop is derived. Both linear and quasi-linear approximations are considered for evaluation of the phase error variance (mean-square tracking error) of the loop. The false-lock performance of the PSK-TLL due to distortion of the digital data caused by the limited bandwidth of the arm filters is also considered. Results are obtained for both NRZ and Manchester encoded data symbols.

In this paper, the alternating-phase fed array with the latticed plate is proposed to improve the antenna efficiency. A waveguide slot with a rectangular cavity, which is an element of the array, is analyzed by the MoM and the influences of the cavity on the slot coupling is discussed. One basis function assumed on the cavity aperture gives accurate results in case that the cavity height ch is over a quarter wavelength and that the cavity width ah is smaller than a half wavelength. It is revealed that the conventional design technique for the resonant slots is available to the proposed array


It is challenging to jointly model dual heterogenous spaces including network topologies and node attributes, especially in the lack of label guidance. Our experimental investigation clearly shows the similarity matrix derived from either the topological or attributed space is distant from the optimal block-diagonal structure, thus it does not reveal salient intra-community compactness. This weakness may severely hinder the capability of recent emerging multi-channel architectures, since some of those channels depending on solo information are in-sufficient. In this paper, we propose a neat dual-channel network embedding architecture. In each channel, attribute information propagates over network topology to node embedding via two independent message-passing manners. To this end, we introduce a graph convolutional filter based simplified symmetric graph autoencoder module. Moreover, a dual self-supervised mechanism acts as consistency regularization by leveraging the soft clustering assignment distribution consistency of unlabeled nodes in different channels, guiding the update of the whole model. Our extensive experiments demonstrate the superior performance of this new method over state-of-the-art methods.


relation, deduced from the simplest formulation of the quantum relation as a generalization of the Poisson bracket (p. 189). The quantum theory, though embodying exact causality, is not deterministic, and its exact laws refer not to co-ordinates and momenta but to probability relations between them. This position, he ruefully admits, was not acceptable to Planck himself, or even now to Einstein, whose letters to himself on this subject he dutifully quotes: Einstein believes in no "dice-playing god." Bom understands by reality the aggregate of observational invariants. This would be all right if physics actually presented such things as mass and energy as invariants. Energy, however, in current physics, (as expressly stated by Born) is not an invariant, but the fourth or time-component of a 4-vector. In fact he attributes to this non-invariance of energy Einstein's deduction of the relation between energy and mass, and de Broglie's intuitional approach to wave-mechanics. In kinematic relativity, on the other hand, energy and mass are actual invariants, taking the same numerical values whatever fundamental observer computes them. But altogether this is a memorable book, and its argumentation floats serenely above the necessarily topical features which accompanied most of the decisive steps by which physics reached the present position in quantum theory, Born thinks that probability and indeterminism have come to stay, and that whatever future developments quantum physics may have in store, they will not be in the direction of a return to determinism.

The crisis in the Russian Orthodox Church, connected with the Patriarch Tikhon's death, initiated the deep divisions between hierarchs. A precedent in the canonical order of the Orthodox Church authorities and nomination of metropolitan of Krutitsy Peter (Polansky) on the Guardian of the Patriarchal Throne were not able to maintain the monolith community. Church was destructed by internal divisions, personal ambitions, manifested especially after the arrest of the patriarchal locum tenes, and persecuted by the communist state authorities. Community was ultimately divided by the taking of the patriarchal throne by the metropolitan of Nizhny Novgorod Sergius (Stragorodsky). Sergius position, de facto deputy of the deputy of the Guardian of the Patriarchal Throne, complicated canonical conflict with the archbishop of Yekaterinburg Grigory (Yatskovskiy) and personal controversies arising between him and the metropolitan of Jaroslaw Agafangel (Preobrazhensky). Internal schizm was finally sealed by the announcement of The declaration of the acting locum tenens of the Moscow patriarchal throne the metropolitan of Nizhny Novgorod Sergius citizen Stragorodsky and the list of the temporary so-called "patriarchal Holy Synod" organized by him about attitude of the Russian Orthodox Church to state authority.


Objective. To study the nursing effect of comprehensive nursing intervention on patients with inflammatory bowel disease (IBD) complicated with hemorrhage undergoing digestive endoscopy under multi-slice spiral CT enterography (MSCTE). Methods. The clinical data of 100 IBD patients
 complicated with hemorrhage undergoing digestive endoscopy under MSCTE in our hospital (February 2018-August 2019) were retrospectively analyzed. They were split into group X and group Y by coin throwing method, with 50 cases in each group. Group Yadopted routine nursing mode while group Xadopted
 comprehensive nursing intervention to compare the nursing efficiency, nursing satisfaction, incidence of adverse reactions, VAS pain score, QLI (life quality) score and PSQI (sleep quality) score between the two groups. Results. The nursing efficiency and nursing satisfaction in group X were
 obviously higher compared withgroup Y. After nursing, the incidence of adverse reactions in group X was obviously lower compared withgroup Y, with a statistically significant difference. After nursing, the VAS pain score in group X was obviously lower compared withgroup Y. After nursing, the
 QLI score in group X was obviously higher compared withgroup Y. After nursing, the PSQI in group X was obviously lower compared withgroup Y. Conclusion. Comprehensive nursing intervention is able to obviously improve nursing efficiency and nursing satisfaction, obviously reduce the possibility
 of adverse reactions in the nursing process, and improve the life quality score, sleep quality score and pain score, which has high application value in IBD patients complicated with hemorrhage treated by digestive endoscopy under MSCTE.


The present invention discloses a hydrostatic pump - hydraulic drive motor unit, the unit having a port from (A) to the high pressure accumulator and a pump for pressurizing a fluid by the mode of action of pressure from the high pressure accumulator the mode of action of the drive motor. The system further comprises a pump - opposite the port (B) of the motor unit and the low-pressure accumulator communicating with a filter circuit disposed therebetween. When the unit is under pumping mode, the filter circuit defines a first flow freely from one port to the low-pressure accumulator (B), and when the unit is in the motoring mode, the filter circuit defining a second flow from the port (B) to the low pressure accumulator. The second process comprises sequentially arranged in parallel through a filter shut-off valve and the filter portion and the flow through another portion of the process flow bore and a valve assembly portion. Thus, the filter effect occurs only in the motor mode, the percentage of the fluid to be filtered may be determined in advance.


Thank you for reading suppression and regulation of immune responses methods and protocols. As you may know, people have look hundreds times for their chosen books like this suppression and regulation of immune responses methods and protocols, but end up in malicious downloads. Rather than enjoying a good book with a cup of tea in the afternoon, instead they cope with some malicious bugs inside their laptop.


The crystallites of semicrystalline polymers formed at low temperatures are subject to partial partial melting and recrystallization resulting in a systematic increase in the size and perfection of the nascent crystallites. Differential scanning calorimetry (DSC) and x-ray studies suggest that ethylene-vinyl alcohol copolymers (EVOH), in particular, may undergo these secondary crystallization processes upon storage at temperatures far below Tm. DSC scans have been run on "as received" and quenched samples; the mole percent of vinyl alcohol in the copolymers studied was 0, 62, 70, 72, 82 and 100 percent. Tests on secondary crystallization kinetics, performed at different temperatures, further confirm the hypothesis of an increased degree of perfection (lamellar thickening) of the bulk crystallites achieved upon long term storage at temperature between Tg and Tm.


Cardiac abnormalities are the main cause of death and ECG is a key diagnostic tool to assess the cardiac condition of a patient. The goal of the 2021 PhysioNet/CinC Challenge was to develop algorithms to diagnose multiple cardiac abnormalities from reduced-lead ECG. In this work, our team csu_anying describe a new model that extracts morphological and temporal features to classify each ECG sequence into 26 cardiac abnormality classes. We use multiple double conv blocks with multiple layers ofsmall convolution kernels to extract morphological features, each layer has similar hyperparameters. Then the Bidirectional LSTM is used to obtain the temporal characteristics. Our entry to the 2021 PhysioNet/CinC Challenge, using the official generalized weighted accuracy metric for evaluation, our classifiers received scores of 0.35, 0.44, 0.43, 0.36, and 0.39 (ranked 25th, 16th, 16th, 21th, and 19th) for the 12-lead, 6-lead, 4-lead, 3-lead, and 2-lead versions of the test set.


Biochemical processes are often modeled as reaction-diffusion systems represented by partial differential equations. However, cells have notable features such as complex structures and high densities of macromolecules, including molecular machines, which are omitted in classical modeling. We have therefore introduced coarse-grained models for processes involving the molecular machines to demonstrate how these features may affect the behavior of biological systems.
