Estimations were made using brains from rats pretreated with normal saline and tremorine. Ambient temperatures of 6, 26 and 360 C were used during the study. Internal standards were included in both brain amine and brain acetylcholine estimations. The values reported in ,ug/g whole brain ± standard error were corrected for recoveries. were noradrenaline 950/%, dopamine 85%, 5-HT 100%, and acetylcholine 78%.


This project explores the nebulizing effect of digital technologies on their analogue counterparts, and their cultural and social repercussions as depicted in early twenty-first-century novels. The thesis finds five central concerns of digital culture, areas in which the structures and codes of the culture have had to be recalibrated to such a degree to accommodate virtuality, and examines them through the works of a novelist with a fascination for, or resistance to this change. The thesis identifies an irreversible shift in the mental apparatus caused by digital technologies that work on narrativizing powers such as memory, interpretation, and perception, that finds expression in fiction.
Chapter 1 reads Jennifer Egan's A Visit from the Goon Squad and The Keep as responses to the phenomena of geomapping, networking and communications in the age of global reach. Chapter 2 uses Tom McCarthy's novels C, Remainder, and Satin Island to illustrate the distorting effects of digitality on time. Chapter 3 brings to focus the more recent work of J. M. Coetzee, Summertime, Elizabeth Costello, and Diary of a Bad Year, that engages with digitality and a cultural landscape increasing reliant on distancing technologies. Chapter 4 examines the recording and surveilling technologies at the heart of Ali Smith's twentyfirst- century novels How to Be Both, Autumn and The Accidental. Chapter 5 reads Dave Eggers' The Circle as a critique of corporate digital culture, and examines the role of taste in articulating personal freedom.
The conclusion analyses a current crisis point in the digital project, and gestures towards the future of technology in the contemporary novel, speculating on what elements discussed in the thesis might endure and shape fictional narrative as the age of digitality progresses.


Abstract Background: Long-term work absence is increasing in Western countries. More people suffer from subjective health complaints, such as musculoskeletal pain and depression-like symptoms. Social rights and benefits are based on medical diagnoses; hence large resources are used to identify the biological causes. An alternative approach towards medicalization and diagnosis, like Salutogenesis, with the key factor "Sense of coherence" (SOC) should be approved. Purpose: To explore the level of SOC, anxiety and depression, as well as the associations between SOC and general resistance resources (GRRs) and deficits, in people with subjective health complaints on long term sick leave. Material and methods: Cross-sectional study, including data from 892 participants from the Friskgården (Norwegian health promotion center) database. The questionnaire included the SOC-13, the Hospital Anxiety and Depression Scale and questions about demographics and sick leave. Multivariable linear regression models were used. Results: Participants' mean (SD) age was 49 (10) years, 70% were women. Mean SOC was 59.4 (13.3). The mean anxiety and depression for all participants were 8.7 (4.4) and 6.2 (3.8) respectively. No difference was found in SOC in participants on sick leave less than, compared with more than one year (p = 0.07). Conclusions: People on long-term sick leave have lower SOC and higher level of anxiety and depression than previously shown in general populations. Large parts of the SOC variation are explained by GRRs and deficits, indicating potentials for improvement by for instance participation in Salutogenic/resource oriented therapy.

Vocational education is the most direct, most significant and most prompt approach in terms of cultivating primary and middle technical personnel, managing staff, technical workers and qualified working staff in all kinds of industry and trade. And it is also the important measures of vitalizing contemporary economy. In order to meet the social needs it is necessary for culinary vocational schools to intensify students' skill training, improve teaching their teaching quality so that they can bring up culinary trade students with strong comprehensive quality.


An autopsy case of an 81-year-old man with a 14-year clinical course of sporadic Parkinson's disease is reported. The patient was apparently well until 63 years of age when he noticed weight loss and was diagnosed as having diabetes mellitus. At 67 years of age, he noticed a gait disturbance, and MRI examination showed cerebral arteriosclerosis withmultiple lacunae located at the corona radiata and thalamus. Based on the neurological examination and the MRI, he was diagnosed as having vascular parkinsonism. Despite medication, the patient's parkinsonism gradually progressed. At age 81, fourteen years after he first noticed a gait disturbance, he developed pneumonia and suffered a cardiopulmonary arrest. Post-mortem examination revealed a pulmonary abscess due to methicillin-resistant Staphylococcus aureus infection and adult respiratory distress syndrome. Neuropathological examination revealed characteristic findings, such as marked neuronal loss in the substantia nigra zona compacta and locus coeruleus, and Lewy bodies immunohistochemically positive for ubiquitin and asynuclein in the remaining neurons. Lewy bodies were also seen in the basal nucleus of Meynert, amygdaloid nucleus, oculomotor nucleus, dorsal raphe nucleus, posterior lobe of the hypophysis, and in the peripheral autonomic nerve system (adrenal medulla, cardiac plexus, and myenteric plexus). Since the patient had no family history of Parkinson's disease, the patient was diagnosed as a sporadic case of idiopathic Parkinson's disease whose death was caused by respiratory distress.


Recent advances in Ground Penetrating Radar have caused the imaging technology to pivot from a simple construction engineering tool to a valuable new option for archaeology. Newfound abilities to model sound echoes resonating through stone have revealed archeological discoveries where excavation is not possible. Working with a transdisciplinary team, the artist secured a GPR scan of 2,000-year-old Gallo-Roman temple ruins below the plaza of a gothic cathedral in France. The technology's sounding image of the hidden site became a visual language that was explored in a 2-year series of artworks based on the discovery. The art + science research project resulted in data visualizations across many creative media including site-specific public trompe l'oeil, augmented reality, and hundreds of design experiments. Using the GPR dataset as a foundational resource in art-making, the project expanded the interpretation of Digital Heritage. Collectively, the works reinforced the understanding of a site hidden since Antiquity but also considered public non-sites in pandemic times. The advances in this scanning technology proved to be a powerful creative tool to highlight themes of how we protect and understand heritage, how we create public experiences in socially distanced times, and our responsibility to continually reconsider complex history.


This paper considers the analysis and synthesis of control systems subject to two types of disturbance signals: signals with bounded power spectral density and signals with bounded power. The resulting control problem involves minimizing a mixed H2 and H∞ norm of the system. It is shown that the controller shares a separation property similar to those of pare H2 or H∞. controller. It is also shown that the mixed problem reduces naturally to H2 and H∞ problem in special cases. Some necessary and sufficient conditions are obtained for the existence of a solution to the mixed problem. Explicit state space formulae are given for the optimal controllers.


Understanding the driving forces of absorption of anthropogenic CO2 by the oceans is critical for a sustainable ocean carbon cycle. Decadal sinking particle flux data collected at 1000 m, 2000 m, and 3500 m at the South East Asia Time Series Study (SEATS) Station (18° N, 116° E), which was located in the northern South China Sea (nSCS), show that the fluxes undergo strong seasonal and interannual variability. Changes in the flux data are correlated with the satellite-derived chlorophyll-a concentration, indicating that the mass fluxes of the sinking particles are largely controlled by the export production at or near the SEATS station. The cooling of seawater and the strengthening of wind in winter increase the nutrient inventories in the euphotic zone, thus also increasing export production in the nSCS. This study reveals that the intrusion of low-nutrient seawater from the West Philippine Sea into the nSCS significantly reduces the productivity, and hence the flux, of sinking particles.


Summary form only given. Photonic crystals (PCs) allow unprecedented control over radiative properties of embedded emitters. High-Q cavities defined in PCs confine photons to small volume, enabling strong light-matter interaction. Lasers in particular stand to gain considerably through decreased lasing threshold, modulation rate, cost, form factor, and device integration. We discuss a THz-modulation photonic crystal laser in a GaAs membrane. The device draws on a multiple quantum well (MQW) gain medium that was surface-passivated using a (NH4)S treatment to reduce nonradiative recombination losses. The increased efficiency alleviates heating problems and allows room temperature operation in pulsed mode, showing extremely fast pulses with FWHM detector in the THz regime and ultra-low-threshold (< 5muW) continuous-wave (CW) lasing at low temperature.


The influence of the buffer layer of hafnia dielectric (HfO2) on the superconducting properties of niobium nitride films (NbN), produced by the technique of reactive magnetron depositing has been investigated for the first time. This study presents a comprehensive analysis of morphological, microstructural, and electrophysical parameters of thin NbN films. The dependence of transition critical temperature on the thickness of the HfO2 buffer layer has been obtained. For the first time, it has been demonstrated that the superconducting properties of niobium nitride films at the HfO2 buffer layer have high superconductive parameters, namely, T c ∼ 13 K (with a the film thickness of approximately 30 nm) and high critical current density of approximately 107 A cm−2. The relation between the thickness of the HfO2 buffer layer with the critical current density of niobium nitride films has been determined. It appeared that the values of critical current density increase significantly up to 13 MA cm− 2 when the thickness of the hafnia buffer layer is more than 2 nm.


Ca(OH)2 nanoparticles in hydro-alcoholic dispersion (nanolime) were successfully employed in Cultural Heritage conservation, thanks to the ability to overcome the limiting aspects of traditional lime treatments. Nanolime were currently produced by chemical precipitation process, at high temperature, with long times of synthesis, and after several purification steps to remove undesired secondary phases. In this paper, an innovative, simple and original method for nanolime production was described. The method was based on an ion exchange process between an anionic resin and a calcium chloride aqueous solution, operating at room temperature. A pure Ca(OH)2 nanoparticles suspension can be rapidly obtained after separating the resin from suspension, and any purification step was necessary. The exhausted resins can be regenerated and reused for a cyclic nanolime production. Structural and morphological features of the produced nanolime were preliminarily characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). Moreover, XRD measurements allowed estimating nanoparticles reactivity by following their carbonatation process in air, in relation to different water/alcohol ratios and medium or high relative humidity conditions. The produced Ca(OH)2 nanoparticles appeared hexagonally plated, with dimension less than 100 nm and, compared with those obtained by typical wet precipitation method, they proved to be more reactive.


The mountain area is faced with complex conditions such as vertical and horizontal valleys, complex geological topography, many earthquake fault zones, high seismic intensity, fragile ecology, and changeable climate. The traditional concrete bridges have a heavy weight, high consumption of sand and gravel materials, large structural dimensions of steel box composite bridges, high steel consumption, and poor overall horizontal performance of steel plate composite beams, which are not suitable for mountain construction conditions. Therefore, based on the construction environment and application requirements of highway bridges in mountainous areas, the structural scheme of steel box-steel plate composite beam is put forward in this paper, and the design of a 25 m–50 m standard-span steel box-steel plate composite beam is studied. The results show that the steel box-steel plate composite beam structure scheme is adopted, which has excellent mechanical characteristics of steel box girder and simple structure of steel plate girder. It has the mechanical characteristics of "balanced transverse force and excellent longitudinal force", so it is a reasonable choice for small radius curved beam bridge in a mountainous area, so it is a reasonable choice for small radius curved beam bridge in a mountainous area. The steel box-steel plate composite beam adopts the integrated technology of manufacture, transportation and installation, which can better meet the road transport conditions in the mountain area. The longitudinal assembly of the manufacturing unit as the installation unit can ensure the rapid and high-precision installation of the construction site, and the assembly construction of the bridge in the mountain area has been realized. The technical and economic comparison shows that the mechanical performance of steel box-steel plate composite beam is similar to that of steel box beam and obviously better than that of steel plate girder. The steel consumption and construction period of steel box-steel plate composite beam are similar to that of steel plate girder, and are significantly less than that of the steel box girder. Therefore, the steel box-steel plate composite beam is a good choice for mountain bridge construction.


In control systems of power grids, conveying observations to controllers and obtaining control outputs depend greatly on communication and computation resources. Particularly for large-scale systems, the costs of computation and communication (cyber costs) should not be neglected. This paper proposes a self-triggered frequency control system for a power grid to reduce communication costs. An equation for obtaining the triggering time is derived, and an approximation method is proposed to reduce the computation cost of triggering time. In addition, the communication cost of frequency triggering is measured quantitatively and proportionally. The defined cost function considers both physical cost (electricity transmission cost) and communication cost (control signal transmission cost). The upper bound of cost is estimated. According to the estimated upper bound of cost, parameters of the controller are investigated by using the proposed optimization algorithm to guarantee the high performance of the system. Finally, the proposed self-triggered power system is simulated to verify its efficiency and effectiveness.


Purpose

This paper aims to examine generational formative referents as factors that influence meeting attendees' adoption and technology use within virtual and hybrid meetings, and test the applicability of the technology acceptance model (TAM) as presented by Davis (1986). This study investigates how attendees' experiences from their respective formative years (i.e. generational formative referents), the basis of the Generational Cohort Theory (GCT), influence the TAM model constructs.

Design/methodology/approach

A partial least squares analysis test is utilized to determine technology acceptance within meetings across three generations: Baby Boomers (1946-1964), Generation X (1965-1978) and Generation Y (1979-2000).

Findings

The multi-group comparison determined all three generations responded similarly with regard to the paths being tested, indicating each of the three generational cohorts within this study are influenced by the experiences of their formative years, which are different for each generation.

Research limitations/implications

The findings add to the limited foundation for scholars wanting to further analyze technology use within meetings, and for those interested in generational influences.

Practical implications

This study provides useful information for marketers and planners to increase meeting attendance, enhance attendee satisfaction, and further explore meeting engagement opportunities.

Originality/value

Underpinning the GCT, this study is the first within hospitality and tourism studies to investigate a theoretical model on generational technology use within meetings.

Foreground segmentation with moving camera is a challenging task due to the presence of parallax effect, registration error, scene variations in out door, and etc. Currently, background modeling techniques either assumes correspondence among pixels in concurrent frames or do not model it explicitly. The contribution by this paper is in two folds. First, we achieve a new background model by introducing correspondence into it. Second, we pose foreground segmentation and correspondence estimation as a labeling problem. Spatial context is enforced in shape of tree structure and global optimal label at each node is computed using dynamic programming. Finally, based on the optimal correspondence, background model is updated. Resultantly, parallax effect and registration error are reduced significantly. Primary experiments proved our algorithm to be robust in performance


SUMMARYThe ultrastructure of the tapetal cells was studied in Kalanchoe obtusa and Pelargonium zonale. In an early stage of development the most characteristic feature was the presence of many spherical bodies bounded by a single membrane and containing cytoplasmic material. These bodies were localized in dilations of the ER and in the perinuclear space. In later stages, when the pollen was mature, the tapetal cells of Pelargonium contained many « grey » bodies and their plasmalemma was in close connection with the sculptures of the pollen grains.


The paper presents the analysis of capacitive losses in GaN devices for an isolated full bridge dc-dc converter. The output capacitances of GaN device are responsible for a significant part of switching losses in a hard switched converter. Detailed knowledge of output capacitance losses is therefore important in the selection of optimum number of devices for a given power level. The analysis is performed on a 130V to 50V, 1.7 kW full bridge isolated dc-dc GaN converter operating at a switching frequency of 50 kHz. The paper also presents the measured efficiency curve of the GaN converter. The converter has attained a maximum measured efficiency of 98.7%.


Secondary analysis of surveys and studies conducted in Israel during the period of 1930-1971 reveals that Israeli women have not achieved a higher degree of equality within the labor force than women in other industrial countries. Moreover the percentage of women in the Israeli Labor force is even somewhat lower. Israeli women, including Kibbutz members, are predominantly occupied in teaching, nursing, clerical work, and sales occupations. A large number of women are occupied in flexible part-time jobs, and except for medicine, Israeli women are underrepresented in all managerial and high status professional occupations.


years. Daring the year the blood bank has continued to operate efficiently, 1,132 pints of blood having been withdrawn from donors on the roll of the Glasgow and West of Scotland Blood Transfusion Service. Apart from transfusions in the infirmary, blood and plasma are sent to other hospitals and to the Royal Technical College, as a result of which many patients in all parts of the area, both Service and civilian, have derived great benefit. There was an increase of 2,350 in the number of cases investigated on the diagnostic side of the X-ray department,


Requirements that have a crosscutting impact on software (such as distribution or persistence) present many problems for software development that manifest themselves throughout the lifecycle. Inherent properties of crosscutting requirements, such as scattering (where their support is scattered across multiple classes) and tangling (where their support is tangled with elements supporting other requirements), reduce the reusability, extensibility, and traceability of the affected software artefacts. Scattering and tangling exist both in designs and code and must therefore be addressed in both. To remove scattering and tangling properties, a means to separate the designs and code of crosscutting behaviour into independent models or programs is required. This paper discusses approaches that achieve exactly that in either designs or code, and presents an investigation into a means to maintain this separation of crosscutting behaviour seamlessly across the lifecycle. To achieve this, we work with composition patterns at the design level, AspectJ and Hyper/J at the code level, and investigate a mapping between the two levels. Composition patterns are a means to separate the design of crosscutting requirements in an encapsulated, independent, reusable, and extensible way. AspectJ and Hyper/J are technologies that provide similar levels of separation for Java code. We discuss each approach, and map the constructs from composition patterns to those of AspectJ and Hyper/J. We first illustrate composition patterns with the design of the Observer pattern, and then map that design to the appropriate code. As this is achieved with varying levels of success, the exercise also serves as a case study in using those implementation techniques.


The Feb. 16, 2004, edition of the Toronto Globe and Mail carried an article subtitled "Canada fails to teach the drama of science." From what I have seen, I doubt that this is a shortcoming peculiar to the Great White North. Under pressure to "get through the material," the tendency is to teach the concepts and theories, without mention of their origin, or at least of the human components of their origin. This is understandable to a certain extent: There seems to be ever more material that we should teach physics majors before sending them off to graduate school or on to the job market. We hope that they will be curious enough, as many of us were, to look into the human factor on their own. This works to some degree, but fails completely when teaching science to nonscience majors.


Abstract Two distinct intraseasonal oscillations (ISO) are found in the tropical ocean atmosphere in the western Pacific region during Tropical Ocean Global Atmosphere Coupled Ocean–Atmosphere Response Experiment (TOGA COARE). The ISO is characterized by cycles of dry–wet phases in the atmosphere due to the passage of Madden–Julian oscillations, and corresponding warming/shoaling–cooling/deepening cycles in the ocean mixed layer (OML). During the wet phase, 2–3-day disturbances and diurnal variations in the atmosphere are pronounced. During the dry phase, diurnal cycles in sea surface temperature (SST) is much enhanced while the OML is shallow. These multiscale coupled air–sea variations are further investigated with an ocean mixed-layer model forced by the observed surface heat, water, and momentum fluxes. The variations of ocean mixed layer are shown to be crucially dependent on the vertical distribution of solar radiation, that is, diurnal SST variability primarily determined by the absorbed solar radi...


100) Agent Oriented Software Engineering (AOSE) is a promising area of research with many potentially useful applications. The use of Roles within AOSE has been noted as an important enabling feature, but there is still much conjecture as to their form and usage. This paper seeks to form a singular description of an Agent Role. So that this Role definition can be used in a wider context, this paper addresses incorporating this Role Model into an existing AOSE Methodology. The paper also looks at the ways in which effective reuse of Roles in Multi Agent Systems can be enhanced.


This article shares some reflections on African theology from an outside perspective. Starting from personal experiences as a German Evangelical coming to South Africa, it basically takes a look at the book African theology on the way: Current conversations , edited by Diane B. Stinton. It wants to identify ways of looking at theology which could be considered in some way or another as 'especially African'. The article then compares these findings with two other books, presenting two different ways of applied African theology: The Africana Bible, edited by Hugh R. Page, coming from a very international background and implementing also the views of African people living outside of Africa, and the Africa Bible Commentary (ABC), edited by Tokunboh Adyemo, featuring an evangelical view. Intradisciplinary and/or interdisciplinary implications: This research gives an outside view on African theology and hermeneutics from an European perspective. It challenges the one-way transfer of theological thinking from Europe to Africa, which for many centuries determined the relationship between the continents. It shows that European theologians indeed can learn much from African theologians and their way of reading the Bible.


Using the daily rain data gauge observations at stations provided by the China Meteorological Administration, NCEP FNL reanalysis data and outgoing longwave radiation (OLR) data provided by NOAA, 67 low-frequency rainfall events are selected from eighteen summers based on the persistent abnormal precipitation index, then, using statistical methods such as power spectrum analysis, Lanczos filtering and phase synthesis analysis to analyze the low-frequency characteristics of persistent abnormal rainfall processes over the Jianghuai region during 2000-2017. The results show that the precipitation period of the persistent abnormal precipitation events over the Jianghuai region lasted 3 8 days on average, and the rain-belt was distributed along the Yangtze River and its south, and the center was mainly located in southern of Anhui and northwestern of Jiangxi. At the lower level (850 hPa), the persistent abnormal precipitation over the Jianghuai region is affected by the low-frequency signals transmitted from the northwest Pacific and the low-frequency signals transmitted from the Hetao region; in the middle level (500 hPa), the persistent abnormal precipitation over the Jianghuai region is mainly affected by the cyclonic system above it and the anticyclone system in the South China Sea-Philippines; in the upper level (200 hPa), the anticyclonic circulations of the South China Sea-Philippines and Barkash Lake, the cyclone circulation on the northwest side of the Jianghuai region, constitute the low-frequency wave train moving northwest-southeast, and corresponding to the active interruption of persistent abnormal precipitation over the Jianghuai region.


Objective: The objective of this study was to determine the frequency, morphological patterns, age and sex and site distribution of vascular tumor in Benin-City, Nigeria. Materials and Methods: The study was a 12 year retrospective analysis of all histologically confirmed vascular tumors seen over a 12 year period at the Pathology Department, University of Benin Teaching Hospital, Benin-City, Nigeria. Results: A total of 162 vascular tumors representing 18.6% of all soft-tissue tumors were analyzed. 136 (83.9%) were benign, 24 (14.7%) were malignant while 2 (1.3%) cases were of borderline malignancy. Hemangioma was the most frequently encountered tumor in this series constituting 71% of all vascular tumors and 84.6% of the benign tumors. Kaposi′s sarcoma (KS) was the most common malignant vascular tumor comprising 14.8% of these lesions. The majority of these tumors were located in the head and neck region (39.5%) followed by the upper and lower extremities accounting for 16.7% and 14.2% respectively. Conclusion: This study has shown that hemangioma is the most predominant vascular tumor and that KS is the most common malignant vascular tumor in this setting. This is similar to previous reports from other researchers locally and internationally.


In this article we compared information from two complementary surveys of managers and union representatives in government workplaces across four jurisdictions in Canada. We explicitly contrasted measures of workplace restructuring between 1995 and 1998 with an aim to explore similarities and differences in how managers and union representatives perceived the changes in their workplaces. We learned that managers were more likely to depict the workplace restructuring in positive terms, while the union representatives were more reserved in their judgment. While we conclude that the differences can be partially explained by compositional, instrumental and structural differences between the samples, we also explain how the divergent interests of managers and union representatives in the restructuring process could lead to perceptual differences we have documented.


One of the main challenges in music improvisation is interactive improvisation between a human and a system. In this thesis we present a musical interactive system (called polyhymnia) acting as melody continuator. For each musical pattern given by the user, it recalls a similar general pattern stored in its memory and reforms it. The proposed system addresses music representation and musical pattern similarity using data mining. We propose a scheme for monophonic music representation as traditional data sets suitable for common data mining algorithms and investigate the application of clustering similarity measures to musical pattern similarity. Data Mining is an emerging machine learning process of extracting previously unknown, actionable information from very large scientific and commercial databases. Machine learning has played a crucial role in the computer music almost since its beginning. Recently, research in the field has focused on music mining. We also present experimental results for testing and evaluating the efficiency and accuracy of the proposed system "polyhymnia".


Soursop plant (Annona muricata L.), is widely used for both industrial and medicinal applications. In view of this, the present study aims at extraction and characterization of soursop leaf wax using gas chromatography-mass spectrometry (GC-MS). The results of the GC-MS analysis of soursop wax show the presence of 26 different compounds. From the results, it could be concluded that A. muricata contains various compounds that could be useful in different industries. Thus, soursop wax could be a good alternative source for many industrial chemicals that are currently sourced from petroleum which is non-renewable.


INTRODUCTION Enediyne compounds have captured the imagination of chemists since the discovery of calicheamicin (1) and neocarsinostatin (2)—natural products three orders of magnitude more potent than other anti-cancer drugs. In following years, other powerful enediyne toxins such as dynemicin, kedarcidin, esperamicin, maduropeptin, and C-1027 were discovered. Preliminary studies focused on the total synthesis and elucidation of the biological mode of action of these natural products.

The abundance and number of protozoan species inhabiting garden loam soil were monitored throughout the winter of 1979–1980 in both undisturbed and crude oil polluted sites. The effect of oil contamination on protozoan colonization was investigated using autoclaved soil cores. Oil did not appear to affect seriously either the encysted or trophic protozoa. Encystment was rapid at temperatures above 0 °C, and the evidence suggests that the soil protozoan population was active for short periods on many occasions throughout the winter.


Although ice sheet internal temperature is a first-order control on glacier dynamics, relatively few in situ borehole temperature profiles exist. The ultra-wideband software-defined microwave radiometer (UWBRAD) was designed to estimate internal ice sheet temperature (<inline-formula> <tex-math notation="LaTeX">$T_{i}$ </tex-math></inline-formula>) by measuring microwave brightness temperatures (<inline-formula> <tex-math notation="LaTeX">$T_{b}$ </tex-math></inline-formula>) from 0.5 to 2 GHz. The retrieval of <inline-formula> <tex-math notation="LaTeX">$T_{i}$ </tex-math></inline-formula> from <inline-formula> <tex-math notation="LaTeX">$T_{b}$ </tex-math></inline-formula> is not straightforward, however, due in part to the complicating effects of ice density fluctuations on <inline-formula> <tex-math notation="LaTeX">$T_{b}$ </tex-math></inline-formula>. In this article, we report a simulation study to assess the feasibility of realizing three science goals: the retrieval of: 1) <inline-formula> <tex-math notation="LaTeX">$T_{i}$ </tex-math></inline-formula> at 10 m depth to within 1 K; 2) vertically averaged <inline-formula> <tex-math notation="LaTeX">$T_{i}$ </tex-math></inline-formula> to within 1 K; and 3) the vertical <inline-formula> <tex-math notation="LaTeX">$T_{i}$ </tex-math></inline-formula> profile to within 1 K RMSE. Two analyses along the Greenland ice divide are presented. First, we assess the ideal UWBRAD <inline-formula> <tex-math notation="LaTeX">$T_{i}$ </tex-math></inline-formula> retrieval precision via the Cramér–Rao lower bound (CRLB). Second, we perform a "virtual experiment" (VE) using synthetic UWBRAD observations. Both the CRLB and VE analyses indicate that the science goals are achievable with the caveats that ice thickness and UWBRAD <inline-formula> <tex-math notation="LaTeX">$T_{b}$ </tex-math></inline-formula> precision impact performance. Assuming a UWBRAD <inline-formula> <tex-math notation="LaTeX">$T_{b}$ </tex-math></inline-formula> precision of 0.5 K, and for places where ice sheet thickness is less than 3 km, all science goals can be achieved. The results of the study provide a strong indication of the potential of UWBRAD to provide valuable Greenland ice temperature profile information to the scientific community.


Objectives: The aim of this study was to compare specificity and sensitivity of different biological markers that
can be used in a forensic field to identify potentially dangerous drivers because of their alcohol
habits.
Methods: We studied 280 Swiss drivers after driving while under the alcohol influence. 33 were excluded for
not having CDT N results, 247 were included (218 men (88%) and 29 women (12%). Mean age was
42,4 (SD:12, min: 20 max: 76). The evaluation of the alcohol consumption concerned the month
before the CDT test and was considered as such after the interview: Heavy drinkers (>3 drinks per
day): 60 (32.7%), < 3 drinks per day and moderate: 127 (51.4%) 114 (46.5%), abstinent: 60 (24.3%)
51 (21%). Alcohol intake was monitored by structured interviews, self-reported drinking habits and
the C-Audit questionnaire as well as information provided by their family and general practitioner.

The constructivism-inspired study on hegemony focuses on the dominant state's ability to shape the beliefs and values of ruling elites in secondary states as a basis of hegemony while paying less attention to the attitude of the mass public in secondary states toward hegemony and the effects of its 'socialisation' with hegemonic ideas. This article provides a conceptual framework for studying the relations between hegemony and the mass-public of secondary states and then subjecting it to a preliminary test against postwar Japan's cooperation with the United States on China policy. The main argument of this article is that hegemony may be strengthened and maintained if the mass public of secondary states is socialised with hegemonic conceptions of world order, state identities and underlying ideologies, and acquires an independent constraint on hegemony. The mass public's socialisation with hegemonic ideas, which amounts to a cultural transformation in secondary states, may take place as a result of propagation by the dominant state and secondary state elites, or as a result of important international and domestic events caused by the hegemon, and then come to feed back on the political structures and processes of secondary states in ways conducive to the maintenance of hegemony. When hegemonic ideas are firmly embedded in the security culture of secondary states, ruling elites in those states may cooperate with the hegemon because they themselves genuinely embrace hegemonic ideas. More importantly, some ruling elites may cooperate with the hegemon out of political expediency as the hegemon-induced cultural transformation may change political structures and processes in such ways as to link the ruling elites' political legitimacy closely with secondary states' continued support for hegemony.


Abstract— This paper presents a new optical system used in an ultra‐thin rear projector with a 1500‐mm diagonal size and 260‐mm depth. A refractive‐reflective optical system was developed to achieve a large projection angle of 136° with a small optical distortion of 0.1%. The optics consists of a convex aspherical mirror and a refractive lens. In addition, a new Fresnel screen composed of hybrid blades of refractive‐TIR (total internal reflection) elements was developed to attain good uniformity of brightness and color within the image area.


This study examined interrelationships among role balance perceptions, adult attachment orientations, and depression within an ethnically diverse, mixed-gender sample of college students. Adult attachment orientations--and particularly attachment avoidance--significantly interacted with students' role balance levels to predict their depression scores. Implications and recommendations for college counseling centers are also discussed. ********** The multiple and sometimes conflicting role demands and responsibilities of college life can potentially threaten students' efforts to maintain a sense of life balance and contribute to their experience of stress and social disconnection (Rice, Leever, Christopher, & Porter, 2006). Students are likely to experience life imbalance when they perceive that they are not harmoniously invested in or satisfactorily coordinating their activities and responsibilities across such life roles as student, employee, friend, intimate partner, and family member. Because many role demands directly involve or implicate one's relationships with others, it is reasonable to conceptualize students' capacities to balance life roles as a generalized, current status indicator of their success in integrating multiple role demands. In this regard, students' more specific orientations toward managing the intimacy-related demands of close relationships (i.e., their adult attachment orientations) may either mitigate or exacerbate the adverse consequences of life imbalance on well-being by prompting the use of distinct interpersonal strategies for managing the complex life role demands of the college environment. Indeed, a number of studies have investigated attachment processes as related to managing and making decisions about life roles in the context of career development (Blustein, Prezioso, & Schultheiss, 1995). Although the experience of a balanced life structure is generally assumed to be associated with higher levels of well-being, there has been surprisingly little research dedicated to the study of lifestyle balance (Christiansen & Matuska, 2006). However, a large literature across many fields (psychology, sociology, organizational studies) exists regarding related research involving role stress. For example, in a recta-analytic review of almost 300 studies involving role stress, Ortqvist and Wincent (2006), who defined role stress as involving separate constructs of role conflict, role ambiguity, and role overload, identified a number of detrimental consequences of role stress, including emotional exhaustion, depersonalization, and fewer personal accomplishments. Many studies have examined the concepts of role conflict and ambiguity as related to job performance (Tubre & Collins, 2000). Additionally, one study investigated contextual factors influencing the anticipated experience of career-marriage conflict specifically among college students (Barnett, Gareis, James, & Steele, 2003). However, the influence of basic interpersonal orientations on the experience of life role balance among college students has been either unexamined or minimally explored. In particular, it remains unclear whether students' adult attachment orientations contribute to the effects of role balance levels on their well-being. To address these important gaps, this study examined the respective contributions of role balance perceptions and adult attachment orientations to a measure of well-being within a large, ethnically diverse sample of college students. More specifically, we examined the independent and interactive contributions of role balance and adult attachment orientations to depressive symptoms. Role Balance Perceptions Marks and MacDermid (1996) defined role balance as "a general cognitive-affective orientation across life roles, an interrole disposition" and as "the tendency to become fully engaged in the performance of every role in one's total role system, to approach every typical role and role partner with an attitude of attentiveness and care" (p. …


The triploid hybrid employed in this study has arisen from the cross between Celosia argentea L. (n=36, Fig. 2) _??_ and C. cristata L. (n=18, Fig. 1) _??_.At the earlier stage of the heterotypic metaphase in P. M. C., all chromosome elements are scattered throughout the cell (Fig. 3). As the stage draws near to the metaphase, bivalents move toward the metaphase plate, and univalents have a weak tendency to move toward the plate (Fig. 4). At the metaphase all bivalents arrange on the metaphase plate and some univalents are present in the metaphase plate with bivalents, but most of the univalents are found at some distance from plate (Fig. 5). In this stage, 18 univalents are often counted in a side view, but it is usual that the number of univalents does not reach expected number. At the polar view of metaphase 36 chromosome elements are counted, but univalents are not distinguished from bivalents (Fig. 6). At the anaphase all univalents are distributed at random to the opposite poles together with the divided halves of bivalents (Figs. 7-9). The univalents have no longitudinal splitting in this stage.Chromosomes lagging behind in the anaphase are frequently observed in the interkinesis (Fig. 11). These lagging chromosomes either form a microcyte in the tetrad formation (Fig. 16), or are lost in the cytoplasm.At the metaphase of the second division all dyad chromosomes arrange themselves in strikingly regular fashion in each of the two daughter nuclear plates (Fig. 12). At the polar view of this stage 27 dyad chromosomes are often found in both daughter cells (Fig. 13). Chromosomes lagging in the first division are also clearly found in the second division (Fig. 14). In the anaphase, chromosomes farming the second division plate divide longitudinally and pass to the opposite poles (Fig. 15).The chromosome behavior during meiosis of the triploid Celosia hybrid is very markedly similar to that which takes place in the Drosera hybrid (ROSENBERG, 1909).The F1 hybrid of C. argentea × cristata contained 54 chromosomes in diploid number, this being the sum of the haploid number in both parents, which had, respectively, n=36 and 18. In the F1 plant, the chromosomes conjugate in such a manner that the 18 C. cristata chromosomes united with 18 of those from C. argentea, the remaining 18 of the latter being left as unpaired chromosomes. 18 bivalents divide in the normal way throughout both divisions. But 18 univalents distribute to the opposite poles at random without longitudinal splitting in the first division, and they divide longitudinally in the second division.


Osmotic coefficients of aqueous solutions of tris(ethylenediamine)cobalt(III) chloride, tris(ethylenediamine)cobalt(III) bromide, tris(ethylenediamine)cobalt(III) iodide, tris(ethylenediamine)cobalt(III) nitrate, and tris(ethylenediamine)cobalt(III) perchlorate have been measured from 0.000 to 0.025 mol-kg −1 . The freezing-point method was used for the determination of the osmotic coefficients. These results were fitted to semiempirical least-squares equations, and these equations were used to calculate the mean molal activity coefficients


Plasma cell dyscrasias comprise a genetically diverse group of diseases such as monoclonal gammopathy of undetermined significance, plasmacytoma, smoldering myeloma, indolent myeloma, and plasma cell myeloma. FISH is superior to CA in detecting important prognostic genetic abnormalities in PCD; however, its sensitivity is hampered due to paucity of PCs in whole BM and often shows false-negative results when frequency of abnormal cells is below the cut-off values. Studies have shown that the abnormality detection rate in EPCs is greater than unselected plasma cells (UPC), but purification techniques are limiting to only FISH when bone marrow volumes are inadequate. The inability to perform CA may compromise patient care since CA is equally important for detecting non-PC related abnormalities, such as secondary myelodysplastic syndrome, when diagnosis is undefined. To resolve this critical issue and optimize limited quantity received, we designed a pilot study where an immnuno-magnetic CD138 enriched positive selection was used for FISH while the negative selection was used to retrieve other myeloid elements for CA. Parallel FISH studies were performed using UPCs and CD138 EPCs, while karyotyping was achieved using whole BM and discarded myeloid elements. Purity of EPC was confirmed by flow-cytometry (47.3% to 96.9%). Results showed that the abnormality rate of EPC (74%) was doubled compared to UPC (34%) for FISH, and CA displayed 100% (16/16) success rate using the discarded myeloid elements. PCD related chromosome abnormalities were confined to whole BM while non-PCD related abnormalities were found in both whole BM and discarded myeloid elements confirming effective removal of PCs by isolation and efficient utility of the supernatant for CA. Significantly higher frequency of IGH rearrangements (36%) and hyperdiploidy (24%) was observed in the EPC group compared to the UPC group (11% for both). Our results confirm the superior diagnostic potential of selecting PCs and demonstrate the feasibility of using the remaining myeloid elements for CA.

This application note describes the key strategies for pesticide analysis with gas chromatography/triple quadrupole mass spectrometry (GC/TQ) using hydrogen as the carrier gas while maintaining sensitivity to meet maximum residue limits (MRLs). The key aspects addressed in this work include the recommended column configuration, the optimized injection conditions, and the appropriate choice of the mass spectrometer (MS) electron ionization (EI) source hardware developed for use with hydrogen carrier gas. The 20 m × 20 m (0.18 mm × 0.18 µm) Agilent HP-5ms UI midcolumn backflush configuration allowed for maintaining the same retention times as with helium, leading to time savings associated with method translation. The resulting chromatographic resolution achieved under the optimal conditions with hydrogen surpassed that with helium. The optimized injection conditions included solvent vent mode, a 2 mm dimpled liner, and the use of analyte protectants. The analyte response with hydrogen was enhanced on average 10-fold when using the optimized conditions compared to using hydrogen carrier gas with the injection conditions, commonly used with helium. Both the Agilent HydroInert and the Agilent High Efficiency Source (HES) resulted in nearly identical spectra observed with hydrogen and helium, which allowed using the same multiple reaction monitoring (MRM) transitions and collision energies as with helium. The ability to use the same MRMs, collision energies, and retention times greatly simplified the transition from helium to hydrogen.


Abstract Chemical or electrochemical one‐electron oxidation of 5‐N‐arylaminothiazoles was found to afford stable radical cations. For chemical oxidation, 1 equivalent of [(4‐BrC6H4)3N][SbCl6] (Magic Blue, MB) was added to CH2Cl2 solutions of the thiazoles, and the thus‐obtained radicals showed light absorption in the near‐infrared region. Electrochemical oxidation also led to bathochromic shifts in the absorption bands, and the obtained spectra were similar to those derived from the chemically oxidized species. These radicals afforded electron paramagnetic resonance (EPR) spectra that are consistent with the notion of stable nitrogen radicals (half‐life≤385 h). The EPR spectrum of a thiazole containing 4‐dimethylaminophenyl groups on the nitrogen atom at the 5‐position changed significantly upon adding >3 equivalents of MB. Details of the electronic structures of the experimentally obtained radical cations were generated from theoretical calculations.


Introduction:
Traumatic brain injury (TBI) is a global issue which affects millions of people and often leaves lasting consequences. Decompressive craniectomy (DC) is a surgical approach for TBI with varied outcomes. Some patients make excellent functional recovery, while others survive with severe disability or fail to recover. If links between pre-operative factors and outcomes are better delineated, clinicians will be better placed to identify patients who are most likely to benefit from DC. By systematically and critically analysing relevant literature, this work aims to identify pre-operative factors linked to better functional outcomes in patients who have undergone DC, resulting in tailored patient-centred approach to TBI management that links with the ethos of precision medicine.
Methods & Materials:
A research question was set using the PICO framework and key search terms were generated. A literature search was performed using the following databases: Ovid Medline, Ovid EMBASE and Web of Science. The review period was set between 2008 and 2018. Overall, 1811 articles were retrieved and systematically assessed using the PRISMA algorithm, SIGN study-design algorithm, CASP checklists and defined inclusion criteria. 10 articles were included in the critical analysis.
Results:
A considerable heterogeneity in the published evidence was noted. Critical analysis of the selected papers identified five factors which may influence functional outcomes: age, admission GCS, timing, imaging and pupil reactivity. Higher admission GCS and lower patient age have been linked with better functional outcomes; however the statistical significance of these findings is ambiguous.
Discussion:
While there is data available, much of it lacks appropriate and robust statistical analysis. Furthermore, studies often fail to reflect current best clinical practice and therefore do not provide tangible and realistic results. Accessing the existing raw data and putting it through rigorous statistical analysis, as a meta-analysis, would allow for more meaningful conclusions to be drawn.


Economic development and reform is a subject that has been explored by countries all over the world, and especially by my country, the largest developing country. In the context of our economic system, each place has its unique economic development model. In this paper, the economic growth model of Jingzhou is derived by studying the economic development data of Jingzhou during the period of fourteen years from 2006 to 2019, using the extended Cobb-Douglas production function to establish a multiple linear regression model empirical analysis simulation. The results show that the economic growth mode of Jingzhou is based on the crude - that is, the growth of the economy relies on a large number of inputs, the adjustment and optimization of industrial structure contributes more to the economic growth of Jingzhou, while other factors on the economic impact is not only inefficient, the contribution is also small, and there is still much room for improving labor productivity and production efficiency.

In frequency-division-duplex (FDD) massive multiple-input multiple-output (MIMO) systems, noisy feedback is a constant challenge for the base station (BS) to acquire accurate downlink channel state information (CSI). In this Letter, the authors propose a convolutional neural network (CNN)-based approach to overcome this problem, which they refer to it as an anti-noise CSI acquisition network (ANCAN). Results demonstrate that ANCAN can reconstruct CSI more accurately than other emerging CSI acquisition methods in the presence of noisy feedback links.


I APPRECIATE the invitation to give this lecture all the more keenly because I believe that up to the present I am the youngest of those chosen for this honour. It is also particularly gratifying to me that Mr Harold Barwell should occupy the chair, as he was the first to teach me the use of the laryngoscope. It might be expected that the opening words of the lecturer should be directed to recall the memory of the Founder, but I think it would be impertinent on my part to say more than this: of the two chapters in laryngology which he may be said to have rewritten, that on cancer of the larynx was one, and therefore I venture to assume that the subject of this lecture would have received his approval. I have done nothing original and I have nothing new to say: " tout homme porte sur Pepaule gauche un singe et sur Pepaule droite un perroquet." Laryngectomy has been widely practised and much discussed in recent years. It has been performed frequently in totally unsuitable cases and has been attended by a high mortality in the hands of many, and in the hands of a few under certain conditions it has been made a safe operation. It seems, therefore, a good time to take stock of the position which laryngectomy holds relative to cancer in and around the larynx, being an operation at first sight so hazardous and severe as to be scarcely justifiable.

Silicon, an important semiconducting material and alloying element in metallurgy and chemistry, is one the most abundant elements in the earth as oxides and silicates. The rapid growth of solar cell demand is creating a shortage of solar-grade silicon feedstock. Expensive high-purity scrap silicon (99.9999999% Si) is mainly used as the raw material to produce solar-grade silicon (SOG-Si) (99.9999% Si). Many researchers have reported that relatively inexpensive metallurgical grade silicon (MG-Si) (98-99% Si) can be used as an alternative raw material. Of all the impurities present in MG-Si, boron and phosphorus are usually the most difficult to remove. Slag refining is one of the few metallurgical methods for the efficient removal of boron from silicon. In order to produce silicon for photovoltaic applications, the relationship between the slag composition and the mass transfer rate of boron from silicon to slag is of great importance.


A capitalization-weighted index is the most common way to gain access to broad equity market performance. These portfolios are generally concentrated in a few stocks and present some lack of diversification. In order to avoid this drawback or to simply diversify market exposure, alternative indexation methods have recently prompted great interest, both from academic researchers and market practitioners. Fundamental indexation computes weights with regard to economic measures, while risk-based indexation focuses on risk and diversification criteria. This paper describes risk-based indexation methodologies, highlights potential practical issues when implemented, and illustrates these issues as it applies to the Euro Stoxx 50 universe.

An efficient, cost-effective hydrogen storage system is a key enabling technology for the widespread introduction of hydrogen fuel cells to the domestic marketplace. Air Products, an industry leader in hydrogen energy products and systems, recognized this need and responded to the DOE 'Grand Challenge' solicitation (DOE Solicitation DE-PS36-03GO93013) under Category 1 as an industry partner and steering committee member with the National Renewable Energy Laboratory (NREL) in their proposal for a center-of-excellence on Carbon-Based Hydrogen Storage Materials. This center was later renamed the Hydrogen Sorption Center of Excellence (HSCoE). Our proposal, entitled 'Designing Microporous Carbons for Hydrogen Storage Systems,' envisioned a highly synergistic 5-year program with NREL and other national laboratory and university partners.


. Neutrino and antineutrino fluxes from a core-collapse galactic supernova are stud-ied, within a representative three-flavor scenario with inverted mass hierarchy and tiny 1-3 mixing. The initial flavor evolution is dominated by collective self-interaction effects, which are computed in a full three-family framework along an averaged radial trajectory. During the whole time span considered ( t = 1–20 s), neutrino and antineutrino spectral splits emerge as dominant features in the energy domain for the final, observable fluxes. The main results can be useful for SN event rate simulations in specific detectors. Some minor or unobservable three-family features (e.g., related to the muonic-tauonic flavor sector), as well as observable effects due to variations in the spectral input, are also discussed for completeness.

Cooperative swarming behavior of multiple robots is advantageous for various disaster response activities, such as search and rescue. This study proposes an idea of communication of information between swarm robots, especially for estimating the orientation and direction of each robot, to realize decentralized group behavior. Unlike the conventional camera-based systems, we developed robots equipped with a speaker array system and a microphone system to utilize the time difference of arrival (TDoA). Sound waves outputted by each robot was used to estimate the relative direction and orientation. In addition, we attempt to utilize two characteristics of sound waves in our experiments, namely, diffraction and superposition. This paper also investigates the accuracy of state estimation in cases where the robots output sounds simultaneously and are not visible to each other. Finally, we applied our method to achieve behavioral control of a swarm of five robots, and demonstrated that the leader robot and follower robots exhibit good alignment behavior. Our methodology is useful in scenarios where steps or obstacles are present, in which cases camera-based systems are rendered unusable because they require each robot to be visible to each other in order to collect or share information. Furthermore, camera-based systems require expensive devices and necessitate high-speed image processing. Moreover, our method is applicable for behavioral control of swarm robots in water.

Villarrica Volcano (Chile) is one of the most active volcanoes in South America. Its low‐frequency (≤5 Hz) seismicity consists of a continuous tremor, overlain by impulsive transient events of higher amplitude in 60‐s intervals. This signal was recorded in March 2012 by an extensive local network, comprising 75 stations and including 6 subarrays. It allowed us to apply and compare three techniques to locate the origin of the seismicity: intersection of propagation directions determined by array analysis, mapping amplitudes, and modeling of amplitude decay. All methods yield almost identical, temporally stable, epicenters inside the summit crater, which confirms earlier attributions of the seismicity to volcanic activity inside the conduit. The discrete transients and the interevent tremor share the same source location. From the dominance of surface waves and the obvious scattering, we infer a source near the surface. For two arrays at the northern and western flank, a dispersion relation was derived, which allowed for the determination of S wave velocity‐depth functions. At both locations, the velocity structure can be modeled by three layers with interfaces at 100 and 400m depths. The velocities (300 to 3,000 m/s) correspond to pyroclastic material at different states of consolidation. The modeling of the amplitude decay reveals a quality factor around 50.

A recent debate concerning the nature of pitch organization in Le Sacre du printemps has brought to the fore central issues in Stravinsky analysis.1 The exchange between Allen Forte and Richard Taruskin epitomizes the broad division between tonalists and atonalists, between analysts who hear in the Rite an inevitable prehistory and therefore develop methods to explain these allegiances, and analysts for whom the radical and modem are uppermost, and who therefore prefer methods that deal with the work "on its own terms."2 However stark the dichotomy appears conceptually, however, its execution rarely succeeds in maintaining consistently each of its perspectives. On the one hand, advocates of atonality are obliged to deal with the uncontroversial contention that no music can be discussed without some reference to its historical circumstances, even where the relationship between the work and its predecessors is an essentially negative one. On the other hand, an analysis whose extent is the detailing of a work's sources, elements, procedures, and gestures, and which makes no attempt to explain


Petteri Pietikainen, who presented his thesis, C.G. Jung and the Psychology of Symbolic Forms, at the University of Helsinki in 1999, has published a new book – this time, in English: Neurosis and Modernity: The Age of Nervousness in Sweden. It deals with the development of a society that became increasingly characterized by a psychological way of thinking. He investigates the period spanning from 1890 to 1950. Pietikainen shows how the concept of neurosis became what is known as a 'contagious diagnosis', and how the process caused terminology like discontent and stress to be adopted into modern everyday language, and that this process is linked to the development of the concept of neurosis.

Introduction Reconstructing the evolutionary history of diverse species is a basic goal of systematic biology and is essential to comparative biology. Phylogenies representing this history are constructed from the analyses of molecular or morphological data and used as tools for understanding the evolution of complex traits. Objectives of this research are to create visualization tools that dynamically reconstruct horn morphology in three-dimensions (3D) for horned lizards and show how changes occur along a phylogeny via metamorphosis (morphing). These objectives will be met by incorporating results from phylogenetic analyses with ancestral trait reconstructions applied to 3-D images generated from a highresolution x-ray computed tomography (CT) scanner. Ancestral reconstruction algorithms are incorporated with nonlinear morphing to accommodate different rates of change along and between lineages. The application of 3-D morphing to systematics and ancestral reconstruction is a novel approach in visualization methods and opens a new realm of collaborative learning and discovery. We believe these tools will provide a greater understanding of how complex traits have evolved by allowing scientists to peer into the past, to see what ancestral states look like, and to visualize changes through time.


The authors present research on alternative basic elements for neural network modeling. A principle that has emerged from this research, which may have important implications for understanding natural and perhaps artificial intelligence, is examined. A paradigm that deals with what and when may be essential for modeling natural intelligence. The authors call such a paradigm a spatio-temporal neural network paradigm. Such a paradigm, which emphasizes real-time, closed-loop interactions between a learning system and its environment, is emerging from research on alternative models of single neuron function. In particular, it is found that neuronal models of classical conditioning phenomena and neural network models of instrumental conditioning phenomena suggest that, as a general principle, real-time considerations may be fundamental to natural intelligence. More specifically, the authors are investigating the hypothesis that learning in biological systems consists of acquired positive and negative real-time feedback loops built on a foundation of innate positive and negative real-time feedback loops.<<ETX>>


Agile development differs from other engineering processes in the manner in which each task is performed, and the ability to respond to changes in scope or requirements. The agile model permits continual feedback after a complete pass through each of the disciplines. Agile development enables the system to be built in a series of cycles from a set of rudimentary capabilities to the full system capability. When agile development is applied to the analysis of complex systems and "wicked problems," the inherent conflicts and inconsistencies of those systems can be resolved. The result of applying "agile" to analysis of a wicked problem is the Design for Tractable Analysis (DTA) framework. DTA analyzes the system (or enterprise) of interest as a whole, in conjunction with decomposing the system into constituent elements for domain specific analyses that are informed by the whole. The use of DTA is demonstrated through a case study of a complex security system.

After a brief description of the layout and status of the VUV-FEL, this paper presents start-toend simulations studying velocity bunching as a scenario for the first operation of the accelerator.


This paper investigates to what extent traditional methods for usability evaluation can reveal problems and issues in pervasive games. The questions of importance for the study could be summarized as: what kind of problems in pervasive games can usability evaluation methods reveal? Which of these problems are general/traditional usability problems, which problems can be related to general problems in computer games and most importantly: which problems are unique for the genre of pervasive games? In order to approach these questions, a pervasive game prototype called "SupaFly", have been evaluated with 58 participants and by use of three standard usability evaluation methods; qualitative questionnaires, system logs and focus group interviews. The problems identified in the evaluation are analyzed and compared to categories and heuristics of previously known usability problems and problems identified in computer games (playability problems) in order to outline the problems unique for pervasive games. Of a total number of 16 issues, six issues were at least partly not covered by traditional usability and playability. Of these six issues, three problematic issues were completely unique for pervasive games: the connection between the platforms of the game (unclear relation between game platforms), the role and meaning of player positioning (unclear role of player positioning (location)) and the level of social interaction (levels of interaction not aligned with social needs).


SUMMARY Five executives suffering from muscular contractions (tension) headache were treated by deep muscular relaxation therapy. Individual sessions were supplemented by practice of relaxation at home, brief relaxation, and cue relaxation during office hours. The effect of therapy, was assessed, by comparing the baseline, pretreatment individual assessment of their behavioral state and self report, with the similar assessment done during and after the successful completion of therapy. The advantages of such an individual assessment & self report in the management of muscular contraction headache are discussed.


Two samples of poly(cis/trans-1,4-cyclohexane dimethanol-alt-formaldehyde), having fractions of trans configuration of cyclohexylene rings Ft = 0.1 and 0.7, were synthesized by polycondensation of the appropriate mixtures of glycols with paraformaldehyde. These two samples were crosslinked by a chemical reaction using 2,4-bis(p-isocyanatebenzyl) phenylisocyanate as the crosslinking agent. The stress-optical behavior of the resulting networks was studied at several temperatures in the range 10–80°C. The values of the optical configuration parameter Δα were 9.9 and 7.2 in units of 10−24 cm3 for Ft = 0.7 and 0.1, respectively. The temperature coefficient of this quantity was roughly zero. Theoretical analysis, performed using the rotational isomeric state model, proved that the only parameters that have an appreciable effect on the calculated values of Δα are those concerning the cyclohexane ring (i.e., Ft and the optical parameter ΓCC = ΔαCC − 2ΔαCH). Conformational energies, geometrical parameters, and contributions to the optical anisotropies from the oxymethylene oxide have no noticeable effect on the value of Δα calculated for the polymer. In fact, values of Δα calculated for the polymer at Ft = 0 and 1 are very close to those obtained, respectively, for cis and trans cyclohexane dimethylene. The theoretical values of Δα are roughly one order of magnitude lower than the experimental results; however, the theory reproduces satisfactorily both the variation of Δα with Ft and its temperature coefficient.


In this paper we present an approach to reasoning with large theories which is based on the abstraction-refinement framework.The proposed approach consists of the following approximations: the over-approximation, the under-approximation, and their combination.


Context. Gigahertz-Peaked Spectrum (GPS) sources are likely the precursors of local radio galaxies. Existing GPS source samples are small (<200). Aims. We aim to extend the available sample of the Gigahertz-Peaked Spectrum (GPS) and High Frequency Peaker (HFP) sources in order to study their nature with greater detail and higher statistical significance. Methods. A sample of 214 radio sources, which were extracted from the SPECFIND catalog and show an inverted radio spectrum, were observed quasi-simultaneously at 4.85, 10.45, and 32 GHz with the 100-m Effelsberg radio telescope. Using the VLBA calibrator survey (VCS) we have investigated the parsec-scale morphology of the sources. Results. About 45% of the sources in our sample are classified as GPS or HFP candidates. We add 65 new GPS/HFP candidates to existing samples. We confirm the expected tendency that HFP are more compact on a milliarcsecond scale than the "classical" GPS sources, which peak at lower frequencies. Conclusions. The data mining of the SPECFIND database represents a promising tool for the discovery of new GPS/HFP sources.


A compact planar broadband millimeter‐wave antenna is presented in this article. The proposed millimeter‐wave (MM‐W) antenna is realized by connecting two pairs of open loop ring resonators (OLRRs). A tapered transmission line is adopted to improve the return loss performance in the required band. Combining these two structures, a new broadband MM‐W antenna is obtained. The measured results show that the proposed MM‐W antenna has a wide bandwidth from 26 to 40 GHz, and all the return losses are less than −15 dB in this band combined with excellent radiation characteristics. © 2007 Wiley Periodicals, Inc.

In this paper we investigate theoretically a system consisting of a Bose-Einstein Condensate (BEC) trapped inside the optical lattice of an optical cavity. It is shown that using the nonlinear atom-atom interaction, how one can manipulate and control the state of the Bogoliubov mode (the quantum fluctuations of the atomic field) and produce squeezed states.


Summary:  Purpose: Episodic loss of consciousness in children, whether or not associated with hypertonia or short‐duration clonic movements, presents a diagnostic challenge to the pediatrician and child neurologist. We provide some evidence of the usefulness of the head‐upright tilt test for investigating the causes of transient loss of consciousness in children, and for distinguishing between syncope, convulsive syncope, and epilepsy.


Background. An upper and lower gastrointestinal (GI) series is an available and informative diagnostic test. Side effects are extremely rare. Objective. To present a case description of portal vein and liver barium embolism with a fatal outcome and explain the mechanism of its occurrence. Material and methods. The clinical manifestations, laboratory and instrumental findings, as well as autopsy of a female patient who died after lower GI radiography were analyzed. Results. To exclude intestinal obstruction, the patient underwent a barium follow through. Three days later, during X-ray computed tomography, barium and gas were detected in the inferior mesenteric vein, portal vein and its intrahepatic branches. During colonoscopy, diverticula of the sigmoid colon were detected, but the localization of the intestinalvenous fistula wasn't determined. Conservative surgery failed and the death occurred 15 days after radiography. Conclusions. The autopsy revealed that the site of entry for the development of barium embolism as well as for gas, were diabrotic veins in peridiverticular abscesses localized in pericolic tissue.


Future advancements in the efficiency and reliability of Industrial Gas Turbines (IGT) will be closely tied to the application of advanced materials, together with increasingly sophisticated turbine hot section designs. An example of this trend is illustrated by the recent design of a first stage blade component for an advanced IGT concept utilizing the third generation single crystal superalloy CMSX-10. It is anticipated that alloy CMSX-10 will permit the use of increased turbine firing temperatures with reduced cooling flows compared to previous recuperated turbine designs, while maintaining acceptable blade durability and life-cycle cost.This paper discusses some of the design/materials analyses and cost studies performed on the blade, which ultimately led to the consideration of alloy CMSX-10 for the IGT application. The solid modeling and finite element blade design methods which allowed the incorporation of state-of-the-art cooling technology and aerodynamics are described. Alloy CMSX-10 characteristics, particularly mechanical properties and microstructural stability considerations, are discussed. Additionally, the results of a recent casting demonstration in an IGT blade configuration are presented. Finally, future tasks supporting the application of the alloy are outlined, such as coatings development efforts and the DOE/ORNL sponsored Land Based Turbine Casting Initiative; activities sponsored through a cooperative agreement with the United States Department of Energy within the Advanced Turbine System (ATS) Program.© 1997 ASME


A key aspect of work-integrated learning (WIL) is the notion that it entails the integration of knowledge and skills gained in the educational institution and in the workplace. WIL educators are interested in what way students take what they learn on campus into the workplace; and conversely how what they learn in the workplace becomes related to, or incorporated into, the next phase of learning when the student returns to the campus after completing a work placement Here we report on a major national study of the pedagogical approaches used in New Zealand WIL programs in terms of integration of student knowledge, and consider what impact these might have on student learning.


It has been demonstrated that it is possible, in the presence of a cationic surfactant, to oxidize copper(II) sulfate (CuSO4. 5H2O) with potassium permanganate in aqueous sodium hydroxide solutions and to oxidize the solid copper(II) sulfate with solid potassium permanganate in methylene chloride. Presumably the surfacant solubilizes the solids and protects the unusual valence from reaction with water. In both solvents, the rate of reaction was fast enough to be followed with an amperometric titration. The stoichiometric reactions in these solvents were found to involve one potassium permanganate for three copper(II) sulfates, indicating that copper(II) was oxidized to in copper(III) while permanganate was reduced to manganese(IV). The results show that both ions and solids, suspended and coated with surfactants, can react rapidly enough for the reactions to be used in titrations and that copper(III) can be formed by chemical reaction and stabilized by a cationic surfactant film.


In order to sufficiently protect active personnel and physical environment from hazardous leaks, recent industrial practices integrate innovative multi-modalities so as to maximize response efficiency. Since the early detection of such incidents portrays the most critical factor for providing efficient response measures, the continuous and reliable surveying of industrial spaces is of primary importance. Current study develops a surveying mechanism, utilizing a swarm of heterogeneous aerial mobile sensory platforms, for the continuous monitoring and detection of CH4 dispersed gas plumes. In order to timely represent the CH4 diffusion progression incident, the research concerns a simulated indoor, geometrically complex environment, where early detection and timely response are critical. The primary aim was to evaluate the efficiency of a novel multi-agent, closed-loop, algorithm responsible for the UAV path-planning of the swarm, in comparison with an efficient a state-of-the-art path-planning EGO methodology, acting as a benchmark. Abbreviated as Block Coordinate Descent Cognitive Adaptive Optimization (BCD-CAO) the novel algorithm outperformed the Efficient Global Optimization (EGO) algorithm, in seven simulation scenarios, demonstrating improved dynamic adaptation of the aerial UAV swarm towards its heterogeneous operational capabilities. The evaluation results presented herein, exhibit the efficiency of the proposed algorithm for continuously conforming the mobile sensing platforms' formation towards maximizing the total measured density of the diffused volume plume.


Paediatric hyponatraemia is usually caused by an excess of antidiuretic hormone and may lead to serious neurological complications. It is challenging for clinicians to differentiate between conditions causing excess water and salt loss. This review analyses individual causes of hyponatraemia and focuses on optimal diagnostic algorithms and treatment strategies.


The present study was conducted to investigate the effects of Sodium Chloride (NaCl) 60 milli Molar (mM) and 80mM on inoculated and uninoculated plants of two cultivars (Williams-82 and its hypernodulating mutant NODI-3) of soybean [Glycine max (L.) Merr.]. The study comprised two sets of experiments. Experiment I was aimed at investigating the changes in Indole Acetic Acid (IAA) as auto regulatory factor for root nodulation and its response under NaCl stress. In this experiment, the changing level of IAA was monitored at 48 h after inoculation, in leaves of potted plants of soybean cultivars, grown under controlled conditions. A decrease in IAA content was found in both the cultivars with salt treatment in inoculated plants. The uninoculated plants showed an increase in IAA content with salt stress. The level of IAA and sugar content was also measured in phloem sap at 0 hour (h), 48 h --- the critical stage of nodule development, and at 192 h after inoculation, that is, at nodule initiation. Sugar content in phloem sap varied in both the varieties. Williams-82 showed more sugar contents in phloem sap while NODI-3 showed more accumulation of sugar in leaves. NaCI treatment reduced the sugar as well as IAA content in phloem sap in Williams-82, while, there was an increase in NODI-3. Experiment 2 was designed to study the effect of inoculation and NaCl (60mM and 80mM) treatment on the root nodulation, yield performance and nutritive quality of soybean. NODI-3 showed more accumulation of sugar in leaves, greater number of nodules plant -1 . Williams-82 exhibited higher protein content in leaves


Ion-exchange reactions are frequently used to develop novel metastable electrode materials for alkali-ion batteries that cannot be synthesized using direct chemical reactions. In fact, the ion-exchange reaction has been proven as an effective approach to develop novel transition metal oxide cathodes for lithium, sodium, and potassium ion batteries.[1-4] However, the solid-state ion-exchange mechanism and the resulting phase evolution are barely understood. In this work, we investigated the electrochemical 'K-to-Na' and 'Na-to-K' ion-exchange reaction mechanisms in layered oxide cathodes as it occurs using operando and ex situ structure characterization techniques.[5-6] Our study demonstrates that the ion-exchange occurs not by a simple Na/K interdiffusion in a given host structure. Instead, we discovered intriguing multi-phase evolutions according to the relative Na/K content, indicating that the ion-exchange systems may be more complex to interpret than the previously understood. We found that not only Na (or K)-layered oxide host interaction but also Na-K interaction affect the ion-exchange reactions. In this presentation, we will discuss how and why those parameters determine the ion-exchange reactions and resulting phase evolutions.

Background Loneliness is a concern among older people living with HIV (PLWH), especially given the ongoing COVID-19 pandemic. Currently, there is little research characterizing loneliness and race. To investigate how HIV impacts older (age 50+) PLWH in the US, a study called Aging with Dignity, Health, Optimism and Community (ADHOC) was launched at ten sites to collect self-reported data. This study uses ADHOC data to compare loneliness between older Black and White PLWH. Methods A cross-sectional analysis was performed to compare loneliness between older Black and White PLWH. Loneliness was assessed using the Three-item Loneliness Scale, a validated patient-reported outcome measure (range 3-9), with higher scores indicating greater loneliness. Student's t-test was used to compare loneliness between White and Black people. Control variables for loneliness were identified a priori and included in a multivariable linear regression model. Results Of 868 participants, the average age was 60 (SD 6.2) years, 77% (N=671) were White and 23% (N=197) were Black, 85% were male, and 82% were gay or lesbian. In bivariate analyses, Black participants were less lonely than White participants (5.2 vs 5.6, P=.02). In the multivariable linear regression analysis, Black participants were again less lonely than Whites (coef. -0.45, P=0.01) while controlling for age, education, depression, anxiety, number of co-morbid conditions, being single, income, gender, sexual orientation, and spirituality (Adjusted R2=0.38;P<.01). Conclusion Among PLWH over age 50 in ADHOC, Black participants experienced less loneliness than White participants, even after controlling for a variety of factors. Additional research is needed to better understand the causes of these racial differences, so that programs designed to decrease loneliness among PLWH can consider the unique characteristics of each group.


This study compared the effects of an integrated reform-based curriculum to a subject-specific curriculum on student learning of 19,526 high school algebra students. Using hierarchical linear modelling to account for variation in student achievement, the impact of the reform-based Core-Plus Mathematics curricular materials on student test scores is compared to the subject-specific curriculum. Findings from this study indicate that students enrolled in integrated mathematics outperformed subject-specific students on an Algebra I exam (highly aligned with content), and performed equally on an Algebra II exam (poorly aligned). High minority students in high-need schools demonstrated higher performance when they were enrolled in integrated mathematics.
