The integration of organic materials with colloidal quantum dots (QDs) has the merits the advantages of the molecular diversity and photoelectric tunability for ultrasensitive photodetector applications. Herein, a uniform CsPbBr3 QD layer is sandwiched between the same poly‐(N, N′‐bis‐4‐butylphenyl‐N, N′‐bisphenyl) benzidine (Poly‐TPD) and phenyl‐C61‐butyric acid methyl ester (PCBM) (1:1) organic blend films. The CsPbBr3 QD layer efficiently absorbs the excitation light, where the generated exciton can sufficiently diffuse to the interface of QD and organic blend layers for efficient charge separation and effective gate modulation. Owing to the desirable heterojunction at the interface, the dark current is substantially suppressed, while the photocurrent is increased in comparison with those of pristine QDs photodetectors. The ultrafast charge transfer time (≈300 ps) from QDs to organic blend layer measured by the time‐resolved transient absorption spectroscopy is potentially benefit the enhanced electron–hole pair dissociation. The solution‐processed, organic (Poly‐TPD:PCBM blend)‐modulated CsPbBr3 QDs photodetector are exhibited ultrasensitive photoresponse abilities in terms of in terms of noise equivalent power (NEP = 1 × 10−16 W Hz−0.5), ILight/IDark ratio (2 × 103), and the a specific detectivity (D* = 4.6 × 1013 Jones). The results will be a starting point for ultrasensitive next‐generation light detection technologies.

Experimental measurements of birefringence and velocity gradient components are reported for steady mixed type flows of a 0.076 g/cm3 solution of 2.89×106 MW polystyrene in a mixed toluene/oligomer solvent. The flow field is produced in a co-rotating two-roll mill with a series of different ratios of the gap width to roller radius chosen so that the flow type at the stagnation point for a Newtonian fluid would range from 0.0196⩽λ⩽0.20, where ‖E‖/‖Ω‖=(1+λ)/(1−λ). Additional data are also reported, for comparison purposes, for a similar polystyrene solution in a simple Couette flow. Finally, the stress-optical relationship is used to obtain a generalized extensional viscosity as a function of strain rate. This viscosity shows a range of strain rate thinning as predicted by reptation theory, followed at a critical Weissenberg number of 0(1) based on the Rouse relaxation time by the initial stages of a region of strain rate thickening, as predicted by the Marrucci–Grizzuti extension of reptation theory that a...


A series of thirteen polyurethanes were synthesiszed using blends of monofunctional, difunctional, and trifunctional poly(propylene oxides) reacted with 4,4'-diphenylmethane diisocyanate in a stoichiometric ratio. Experimental measurements were made of glass transition temperature, sol fraction, and dynamic mechanical properties. Computer simulations based on the theory of branching processes were made on the same systems. The glass transition temperature was correlated with the number average functionality of the components. Dynamic mechanical data was fitted to the Havriliak-Negami model. A correlation was demonstrated between the measured rubbery modulus and the concentration of elastically active network chains.


From 1997 to 1999,we carried out an investigation on the bird fauna of wetlands along the Old Yellow River Course Nature Reserve in northern Henan Province. The study revealed that the birds in this area belong to 16 orders, 37 families, and 119 species. Among them, 32 species are residents (26.9%), 24 species are winter migrants (20.17%), 30 species are summer migrants (25.2%),and 33 species are passage migrants (27.7%). Two species are Class I protected, 19 species are Class II protected, and six species are provincially protected.


Several pyrazoloquinolinone (PQ) ligands were recently discovered as functionally selective positive modulators at the PQ site of α6‐containing GABAA receptors. PQs are also neutral modulators at the benzodiazepine site. We assessed the influence of PQ compounds from three structural groups (PZ‐II‐029 and related deuterated analogues DK‐I‐56‐1, RV‐I‐029, DK‐I‐60‐3 and DK‐I‐86‐1; LAU 463 and related analogues DK‐I‐58‐1 and DK‐II‐58‐1; and DK‐I‐87‐1), alone and in combination with diazepam, on the behaviour of male Sprague–Dawley rats. An excellent behavioural safety profile of all tested PQs was demonstrated in the spontaneous locomotor activity, rotarod, loss of righting reflex and pentylenetetrazol tests. In interaction studies, only PZ‐II‐029 and its analogues prevented the ataxic effects of the benzodiazepine, as assessed in the rotarod test and during monitoring of rat locomotor activity after awakening from the loss of righting reflex. Published electrophysiological profiles of PQ ligands imply that positive modulation elicited at α6‐GABAA receptors that contain the γ2 and δ subunit, rather than their neutral modulatory action at the benzodiazepine site, may prevent the ataxic action of diazepam. Thus, PZ‐II‐029 and its deuterated analogues are not prone to untoward interactions with benzodiazepines and may indeed completely abolish their ataxic action, seen at therapeutic, and especially toxic concentrations.


This research examines whether managerial skills obtained at Academy in postgraduate courses like the specialization in senior management encourages students to the creation of new companies in Colombia or if instead the interest of many professionals is to direct companies already established, on the other hand it is important to relate which basic, generic or specific skills which should take into account or take on greater importance to manage or direct for this review of the concepts of leadership, emotional intelligence, is done in order to achieve more effective results to lead work teams.

This research describes women in the tradition of proposing to find a child in the Mergomulyo community. This tradition is believed to be able to perpetuate domestic relations. On the one hand, this tradition is considered to be detrimental to women because of the anomaly of norms in its implementation. The research focus is on the position of women in the tradition of finding children from a feminist perspective. And the existence of women in the tradition of finding children from the perspective of Peter Burger's social construction. this type of empirical research using descriptive qualitative approach, data obtained by observation and semi-structured interviews with perpetrators of finding children. The results of this study show that the position of women's sexuality is entangled in established patriarchal cultural values. Male dominance is very thick. Women are sexually marginalized and do not have a role and decision in enjoying their reproductive rights because of the hegemony of men in the name of tradition. This phenomenon tarsus is maintained because it has been massively constructed. Marked by the moment of externalizing oneself with the socio-cultural world, it is marked by an adjustment to the values in the tradition which are conditions for patriarchal culture. moment of objectivation, institutionalization and habitualization in this traditional process played by male agents. Moment of Internalization, which is self-identification in the sociocultural world, women assess the social reality of the tradition to be a subjective and true reality. This shows that women's actions, roles and abilities in making objective decisions have blurred over the dominance of patriarchal cultural values.


W Paul Ricoeur asks in his great trilogy, Time and Narrative, is the basis for the permanence of the proper name that designates an individual or a group? The response to this question, he argues, is condemned to an antinomy with no solution. Either the subject has to possess some fundamental sameness through time, despite apparent change; or, and here he cites Hume and Nietzsche, there is no such permanence: there is in reality no identical subject moving through time that the proper name designates. Ricoeur posits a different concept of identity: not as the same (idem) but as self-same (soimeme or ipse). "The difference between idem and ipse is nothing more than the difference between a substantial or formal identity and a narrative identity." In other words, to answer the question "Who?" is to tell the story of a life. The subject, Ricoeur suggests, is both author and reader of its own life. And the story of that life is continuously reconfigured. The permanence of the proper name as narrative identity, unlike the abstract identity of the same (idem), thus includes change within continuity. This notion of narrative identity is not applicable only to individuals but also to groups, which in similar ways constitute their identity by taking up narratives that become, for them, their real history. The story of a group is constituted in time by a series of modifications to these narratives that both preserve and adjust that group's narrative identity. In other words, their narrated past changes in order to stay the same. Ricoeur points to biblical Israel as such a narrative community: "It was in telling these narratives taken to be testimony about the founding events of its history that biblical Israel became the


Doping is an effective strategy to tune the electrical properties of organic semiconductors. Traditional solution‐processed doping methods, including "host‐dopant mixing‐doping" and "post‐fabrication doping" methods, present challenges for their use in applications in optoelectronic devices. This work reports about a novel method to prepare electrically doped films, the authors call orthogonal liquid‐liquid‐contact (OLLC) doping. In OLLC doping, dopant and polymer semiconductors are dissolved in water and an organic solvent, respectively, and electrical doping occurs during film formation at the orthogonal liquid‐liquid (aqueous‐organic) interface. A large free volume of polymer and dopant in their solutions enables diffusion for effective doping. Thanks to the high surface tension of water, nanometer‐thick polymer films form spontaneously on the aqueous surface and simultaneously get doped. The doped thin polymer films on the aqueous surface can be easily transferred to devices to facilitate hole collection/injection in organic photovoltaics and light‐emitting diodes with solution‐processed top electrodes.


Zinc is known to play a relevant role in growth and development, it has stimulatory effects on in vitro and in vivo bone formation and an inhibitory effect on in vitro osteoclastic bone resorption. The inorganic component of the bone tissue is nonstoichiometric apatite; changes in the composition of hydroxyapatite (HA) are subject of studies in order to improve the tissue response after implantation. The objective of this study was to investigate the effect of 0.5% zinc-containing hydroxyapatite (ZnHA) in comparison to hydroxyapatite (HA, control group), on osseous repair of rabbit's tibia. Cylinders (2X6mm) of both materials were produced according to the specification of the International Organization for Standardization (ISO). Ethics Commission on Teaching and Research in Animals approved this project (HUAP-195/06). Fifteen White New Zealand rabbits were submitted to general
anesthesia and two perforations (2mm) were made in each tibia for implantation of ZnHA cylinders (left tibia) and HA cylinders (right tibia). After 1, 2 and 4 weeks, the animals were killed and one fragment of each tibia with the cylinder was collected, demineralized and 6-μm thick semi-serial sections were done for histomorphometric analysis. The second fragment of each tibia was collected and embedded in a
methacrylate-based resin and cut into slices (~30 μm and ~200 μm thickness), parallel to the implant's long axis with a precision diamond saw. The specimens with ~30 μm thickness were analyzed by light microscopy (bright field and polarized microscopy). For the Scanning Electron Microscopy and Transmission Electron Microscopy it was used an entire metalized resin block and slices with ≅70-90nm, respectively. The histomorphometric analysis revealed after 28 days that the zinc containing hydroxyapatite group showed greater area of new bone formation (p<0,05). The X-Ray Fluorescence, Atomic Absorption Spectroscopy and X-Ray Microfluorescence confirmed the presence of zinc in the experimental ZnHA specimens, however in lower quantity than the theoretical dose. The TEM and SEM
analysis showed heterogeneous grains and cylinders surface, respectively. The Xray diffraction showed a decrease of ZnHA crystallinity and a new phase (CaZnTCP) was formed after the thermal treatment. The accomplishment of the standard procedures helped the planning, execution and the comparative analysis of the results. The chemical and physical properties of the biomaterials were modified after
its implantation and the incorporation of zinc. Both materials are biocompatible and promote osteoconduction and no difference was found between the materials in bone repair


The role of regional forums could be better defined in the follow-up and review process, which can be done through: ● Regional VNR submission of interim VNRs to the regional forums for comments and inputs, and subsequently submit the final reports to the HLPF. The year after countries report, a follow up report is submitted to the regional forums – this will lead to greater accountability ● More sessions of the HLPF should be dedicated to systematically integrate regional forum perspectives to inform global processes. To further enhance the process, a continuous feedback loop should be created to flow back from HLPF into regional, sub-regional and national levels to track the implementation of recommended actions. ● The recommendations should also be directed at the national and regional level UN systems (including Resident Coordinators, specialized agencies and country missions), for complementarity and accountability. ● The outcome document from the regional processes (report and Chair summary) should be integrated with the ministerial declaration of the HLPF. ● Lastly, participation of civil society in regional follow-up mechanisms should be systematically enhanced through allocations of spaces as well as financial resources.


Emotions are conveyed every single second, and understanding what they typically represent is crucial in practically every industry. People's ability to accurately recognise emotions varies greatly, making technology utilized for the purpose a relatively new subject of research. We attempted to work on extracting significant features from the image datasets and feeding those characteristics to a CNN in this study to aid the emotion detection for the CKplus and JAFFE dataset. The two separate extraction techniques employed are the Gabor filter and SIFT. The extraction techniques assist in identifying the main attributes that contain a profusion of visual data.The experimental investigation demonstrates that the gabor filter paired with CNN outperforms the state-of-the-art performance using the CKplus dataset, with an overall accuracy of 98.12.


Geothermal energy is an appealing source of baseload renewable energy capable of supplying constant energy regardless of seasonal and other environmental factors. Benefiting from subsurface natural heat anomalies, geothermal energy projects have been developed primarily on igneous and metamorphic environments where temperature gradients are elevated near the surface. Hard rock combined with high temperatures and a corrosive environment makes geothermal drilling difficult and expensive. However, the access to hot reservoirs is not limited to igneous and metamorphic environments. Fields with downhole temperatures of 150  C and above are present in reservoirs 3 to 4 km depth in sedimentary basins in the US. Sedimentary environments have the advantage of large quantities of existing subsurface datasets and lower cost to drill. Additionally, the porosity and permeability in sedimentary basins are more favorable than traditional geothermal reservoirs, allowing for improved flow potential and heat extraction. In this paper, a technical, economic evaluation is performed to ascertain the potential geothermal development in a sedimentary field in the Gulf Coast area in Texas. Various reservoir simulations with different wells configurations were analyzed. Furthermore, the use of existing oil and gas wells, combined with new vertical and horizontal wells, is evaluated. A sensitivity analysis indicates that permeability and fracture density affect the heating extraction rate. Also, the variation in the wells' position and configuration affect the energy production. Finally, we conclude that the project of heat extraction for power generation in the area evaluated is technically Texas Gulf Coast. The novelty of this approach is the combined use of existing oil and gas wells as injector wells, and a new horizontal well for production. To assess the potential of the project, logs from existing wells in the area were used to build the reservoir model. Petrophysical properties combined with geothermal gradient data were used as input to determine potential new well locations. This enables to evaluate the impact of well positioning in the energy output of the

In this paper, a game interface for children with learning difficulties designed to enable learning and training the interaction with a QWERTY keyboard, therefore enhancing digital literacy and inclusion, is presented. Specifically, the interface presented writing activities with several difficulty levels, from monosyllabic to polysyllabic words, allowing the training with the QWERTY Keyboard. To assess usability of the interface we performed a preliminary user test with ten children with learning disabilities and it was register the following usability variables: efficiency, effectiveness and satisfaction. The main results showed that children improved their performance with the keyboard throughout the activities but showed spelling difficulties in higher difficulty levels. These difficulties were not in interaction with the QWERTY keyboard but in the word spelling. Still, all conclude tasks with success, no one dropout.


Abstract This paper attempts to study the dynamic soil–pile interaction on the non-linear response under coupled vibration by both experimental and analytical study. Dynamic response characteristics of reinforced concrete piles under varying levels of vertical and horizontal harmonic excitation are investigated in the present study. Single and group (2×2) piles are used in the investigation. The horizontal exciting force applied on the pile cap through the oscillator causes coupled motion to the foundation. The measured response is compared by the two different analytical approaches: linear analysis – Novak's plane strain theory with static interaction factor approach and non-linear analysis – Novak's continuum model with dynamic interaction factor approach. For non-linear analysis, allowance is made for the separation between the pile and soil in boundary zone model. Reasonable match between the measured and predicted response by non-linear analysis is found. The test data are used to establish the empirical relationship between the extent of soil separation around the pile and the maximum vibration amplitudes under coupled vibration.

Progressive decline in cognition and renal function are both related to ageing. The estimated global prevalence of dementia was 55 million people in 2019, a number expected to increase to 139 million by 2050. Furthermore, chronic kidney disease (CKD) is the second fastest growing cause of death globally. Few studies have examined the link between these conditions. In this study, we examine CKD and estimated glomerular filtration rate (eGFR) in relation to plasma neurofilament light protein (P‐NfL) and volumetric magnetic resonance imaging (MRI) measures of Alzheimer's disease‐specific and general neurodegeneration.


This thesis evaluates software-based energy estimation methodologies for wireless sensor nodes in terms of feasibility and estimation accuracy. It contains an extension of todays most widely used estimation model, which incorporates the state transitions of the radio transceiver. The improved model introduces a higher level of granularity which is shown to have a positive impact on the accuracy of the resulting estimations. This claim is backed up with numerous experiments based on the MSB430 sensor node platform with the ScatterWeb [16] operating system and different MAC protocols. The MAC protocol prototypes used in the tests consist of the CSMA/CA, S-MAC, T-MAC and WiseMAC protocols. The prototype implementations of these protocols are explained in detail in the course of the thesis. To quantify the error rates, we determined the power consumption of a wireless sensor node through hardware-based measurements and estimated the power consumption with an energy estimation model at the same time. The difference between the physically measured energy consumptions and the estimated values served as the statistical measure for the evaluation.


Thedevelopmentoffetalbrainisinfluencedbynutrientssuch as docosahexaenoic acid (DHA, 22:6) and choline. Phosphati-dylethanolamine- N -methyltransferase (PEMT) catalyzes the biosynthesis of phosphatidylcholine from phosphatidylethanol-amine enriched in DHA and many humans have functional genetic polymorphisms in the PEMT gene. Previously, it was reported that Pemt (cid:1) / (cid:1) mice have altered hippocampal development. The present study explores whether abnormal phosphatidylcholine biosynthesis causes altered incorporation of DHA into membranes, thereby influencing brain development, and determines whether supplemental dietary DHA can reverse some of these changes. Pregnant C57BL/6 wild type (WT) and Pemt (cid:1) / (cid:1) mice were fed a control diet, or a diet supplemented with 3 g/kg of DHA, from gestational day 11 to 17. Brains from embryonic day 17 fetuses derived from Pemt (cid:1) / (cid:1) dams fed the


In human services that provide human-interpersonal services, it is known that experience at the service encounter affects customer's survival and that customers have loyalties to a service provider rather than to a shop. For this reason, it appears that management would be seriously damaged if the service providers leave their jobs or transfer to another shop. Therefore, it is helpful for managers to estimate turnover risks and transfer effects at a human service company. In this paper, we propose a methodology for simulation analysis of the influence of service-provider turnover and transfer in the human services business. Our methodology provides a modeling framework to build an operational simulation model for analyzing the risk of staff turnover and transfer in the human-services business, from the viewpoint of organizational cybernetics and computational organization theory. Our methodology also identifies the tasks required in the modeling process and provides guidelines for model validation and scenario analysis. We applied the proposed methodology to simulation analysis of the turnover and transfer impact of service providers in a hair salon company with several shops.

Using negatively charged PS ultrafiltration membrane as substrate,multilayer PDADMAC/PSS polyelectrolytes nanofiltration membranes were prepared by layer-by-layer self-assembly technology.The membrane surface morphology,charging property,as well as the effect of concentration and types of the support electrolyte on the membrane performance were investigated.The results indicated that the prepared NF membrane surface was uniform and with no defect;the values of negative charge on membrane surface first gradually increase with the bi-layer number,and then gradually decrease with the bi-layer number,which demonstrate that there should be an optimal concentration of the support electrolyte.In addition,the performance of the(PDADMAC/PSS)5 NF membranes prepared in optimal conditions was evaluated.The results showed that under 1.0 MPa,the Na2SO4(2 g/L) rejection was 93%,and the corresponding flux was up to 60 L/(m2·h);the NaCl rejection was only 9%~13%,while the flux could reach 80 L/(m2·h).The prepared NF membrane could be completely used for the separation of univalent and bivalent salt solution system.The variation of contact angles reflects the alternative self-assembly of the polyelectrylytes.The prepared NF membranes with PSS as surface layer have excellent hydrophilic property.


With the continuous improvement of global information technology, the era of big data is coming. Network technology has penetrated into all areas of social development, and has also brought unprecedented challenges and opportunities to university research. Governments around the world attach great importance to the application and development of big data technology; and universities are also researching and exploring the application of big data technology in the field of scientific research. At present, many universities in developed countries have established a relatively complete application system of big data, and adopted a series of methods and ways to promote the use of big data in the field of scientific research in colleges and universities, forming a lot of valuable experience, which has brought enlightenment to the research and utilization of big data in other countries.


Dental malocclusion is altered growth and development, with the anterior open bite defined as the negative vertical overlap between the incisal edges of the anterosuperior and inferior teeth. Considered a complex anomaly, difficult to treat and with a high degree of impairment of the facial and aesthetic balance, it generates significant dental and skeletal alterations. The aim of this study is to study a case and review the literature on the etiology and treatment modalities of anterior open bite. In the present study, an infant-juvenile patient with mixed dentition and presence of anterior open bite was selected. In this patient, the interceptive device, McNamara with lingual grid, was installed. After 4 months of use of the orthodontic device, correction of the anterior open bite, improvement in facial harmony and lingual interposition was observed. It is concluded with this work that the treatment of this malocclusion should be performed early and preferably in a multidisciplinary manner. It is of great importance that dentistry professionals know the main etiologies for the development of this malocclusion, since early intervention results in better results and greater stability of the treatment, besides directly interfering in the quality of life of the patient by restoring the correct functioning of the stomatognathic system.

We study the seller's optimal two-period pricing policies when speculative behaviors exists: strategic customers with heterogenous valuation make the tradeoff among price, consumption valuation, speculative benefit and availability to decide whether to be a consumer or transfer into speculators. We get the speculators' resale behavior and the seller's pricing decision. Our research suggests that the strategic customers with valuation being in a middle range will choose to speculate. Besides, we propose the speculators and seller's optimal pricing strategies.


This article aims to analyze The free negress Elisabeth: prisoner of color (2004), a historical novel from Suriname (country that is part of the Guiana region) written by Cynthia McLeod. The focus given to the research intends to problematize the way the place of speech acts in the construction of the fiction, highlighting historically silenced voices. In addition, the study of the place of speech of black women during the Dutch colonization in Suriname aims to contribute to the debate on racial and gender inequality that underlies colonial societies and remains to today. For the discussions, this research will be based on the reflections of Akotirene (2019), Morrison (2019) and hooks (2015), among others.


Abstract : This report concludes that demonstration of Decision Science's top down methodology has conclusively shown the capability to relate commodities, sources, stockpile requirements, military assets and the external environment (military, political and socioeconomic) in a dynamic, interactive evaluation of strategies relative to the strategic and critical material stockpile. With this adjunct to existing Federal Emergency Management Agency (FEMA) Models, FEMA will have the analytic tools necessary to simulate the various strategies and thus achieve a better outcome of the vital decision process as it relates to the assurance of national security. Further, the definition of the Joint US/USSR Purpose enables, for the first time, a quantitative evaluation of the interactions of the superpowers and how these affect our stockpile strategies. This is a key asset for use in stockpile strategy formulation, considering the moves and countermoves of the major protagonists in the arena of critical materials.

When a project fails to clarify important issues, to complete the analysis, or to make clear statements where the system is meant to be extensible and where it needs to be stable, architects tend to answer the indecisiveness in a technical way: general and complex solutions. This diagnosis pattern is about the balance between making decisions and introducing variability and configurability. It shows why unmanaged complexity is a major risk to the project's success, how it creeps into a project and how to detect it. Furthermore it gives techniques how to enforce decisions and limit the generality. A note to the workshop participants Primarily I seek feedback on the completeness of the symptoms, the correctness of the causes, and the applicability and completeness of the therapies.


IN a previous investigation [Robson, 1936 a] it has been shown that when the pituitary is removed in the later stages of pregnancy, the abortion which otherwise follows within 24-48 hours can be prevented by the administration of extracts of the corpus luteum and of the crystalline hormone progesterone. It has also been shown that the luteal function can be maintained in animals hypophysectomized during pseudo-pregnancy by the injection of small maintenance doses of gonadotropic hormone [Robson, 1937]. The aim of the present investigation was to determine: (1) Whether the crystalline corpus luteum hormone, progesterone, would maintain pregnancy in animals hypophysectomized at earlier stages of gestation, and (2) Whether the administration of gonadotropic hormone to animals hypophysectomized at various stages of pregnancy would result in the maintenance of the luteal function and thus ensure the continuation ofthe gestation. In addition a number of experiments on the role of the pituitary in the development of the mammary gland were made.


Monocytes play important roles in inflammation, angiogenesis and tissue repair and may contribute to the pathophysiology of heart failure (HF).


Island is the largest electronic communications network in the US. On March 18th 2002, it began reporting trades to the Cincinnati Stock Exchange (CSE) to reduce costs. We use the information generated following this trade reporting change to analyze differences in trading characteristics and trading costs between Island and NASDAQ. The results indicate significantly lower effective spreads, percentage effective spreads, and traded spreads for Island trades. There is more trade price clustering on nickels, dimes, and quarters for NASDAQ trades.


Gallium Nitride (GaN) possesses superior electronic properties for RF power electronics that play critical roles in various wireless communication technologies and military applications [1]. Heat generated as a byproduct of operation in these devices, increases their operating temperature and degrades their performance and lifetime. While bulk GaN has a high thermal conductivity (k) approaching 250 W/m-K, [2, 3] GaN thin films and devices experience a much lower k due to the presence of additional phonon scattering mechanisms and departures from Fourier transport [4, 5]. We will review thermal transport in GaN based devices, broadly addressing the impact of heat source dimensions, film thicknesses, interfaces, and defects.


ABSTRACT Fossil fruits of Icacinaceae are recorded from two Cenozoic sites in Australia, at Launceston in northern Tasmania and the Poole Creek palaeochannel in northern South Australia, representing the first report of fossil Icacinaceae from Australia. The Launceston material includes two endocarps with broad surface pits/tubercles and is referred to Palaeophytocrene. It is interpreted to have a minimum middle to late Eocene age. Two specimens are recorded from the Poole Creek palaeochannel; a mid-Miocene or middle Eocene age is possible for this site, but the older age (middle Eocene) is considered more likely. These specimens represent partial endocarps, one documenting the wall thickness and internal structures of the endocarp, and the other documenting the morphology and dimensions of the endocarp surface pits. The combination of characters shown by these fossils is unique among extant and fossil Icacinaceae genera, warranting the recognition of a new genus, Manchesteria gen. nov. These fossils document an early Cenozoic history for the Phytocreneae (Icacinaceae) in Australia and provide additional evidence that the family was broadly distributed during the globally warm Eocene. Along with recently documented African and South American fossil records, these fossils indicate a significant but little understood Gondwanic history for the family.

This article investigates the design of a series of new chaotic attractors. A switching control with different switching surfaces is designed to link two systems of linear integer order differential equations. Under such control, the linked systems have rich dynamical behaviors such as chaos. We also investigate the dynamical behaviors of the corresponding linear fractional order differential equation systems with switching controls. It is shown that such fractional order systems have chaotic behaviors as well.


Background: Permanent hearing loss is one of the most common congenital disorders, with an estimated incidence of one to three per thousand live births far exceeding the combined incidence of conditions for which newborns are routinely screened. Objective: The aim of this study was to estimate the incidence of hearing loss in newborn at Qena University Hospital, for early diagnosis, early intervention and good prognosis. Patients and Methods: This cross-sectional study was conducted at Qena University Hospital and 100 neonates were examined. The study was conducted in a duration of 6 months. Results: There was statistically significant relationship between the presence of risk factors such as prematurity, hyperbilirubinemia, hydrocephalus, respiratory distress syndrome, and amplitude of frequencies in both ears, there was no correlation between amplitudes of frequencies in both ears and age, heart rate, respiratory rate, incubation period or temperature. Conclusion: It could be concluded that otoacoustic Emission (OAE) is a reliable test for newborn hearing screening. Although all the 200 ears passed the screening test at Qena University Hospital, this does not guarantee a low prevalence of hearing loss but due to the limited number of cases and short duration of the study.


This paper introduces a new method for representing two-dimensional maps, and shows how this representation may be applied to concurrent localization and mapping problems involving multiple robots. We introduce the notion of a manifold map; this representation takes maps out of the plane and onto a two-dimensional surface embedded in a higher-dimensional space. Compared with standard planar maps, the key advantage of the manifold representation is self-consistency: manifold maps do not suffer from the 'cross over' problem that planar maps commonly exhibit in environments containing loops. This self-consistency facilitates a number of important autonomous capabilities, including robust retro-traverse, lazy loop closure, active loop closure using robot rendezvous, and, ultimately, autonomous exploration. By way of validation, this paper also includes experimental results obtained using teams of two to four robots in environments ranging in size from 400 m/sup 2/ to 900 m/sup 2/.


Photon+jet events are generated using PYTHIA 8 and their fraction of quark-jet and gluon-jet events are studied by mapping the photon+jet production to parton densities. Measurements had shown that photon+jet momentum imbalance and azimuthal angle correlations have wide distributions even in the absence of a QCD medium. Sources of widening are investigated via parton level processes in PYTHIA 8, finding that initial-state radiation is the dominant source. Correlations at RHIC energies are shown to have sharper distributions than those at LHC energies, as the effects of vacuum processes become smaller with lower collision energy. Sensitivity of jet observables to the heavy-ion underlying event (UE) are studied using toy events. Jet observables are compared between jets recombined with E-scheme and winner-take-all (WTA) schemes. The jet pointing angle in WTA scheme is found to be much less sensitive to the heavy-ion UE.


Slice emittance measurements with uncompressed beams at the SwissFEL Injector Test Facility have demonstrated emittances for bunch charges between 10 pC and 200 pC well below the tight requirements of the SwissFEL planned at the Paul Scherrer Institute. We present the measurement methods, emittance tuning strategies and results of this effort.


Objective:To explore the relationship between Thyroid Stimulating Hormone(TSH) level and blood lipid and uric acid(UA) in the elderly population.Methods: 123 cases with abnormal TSH level(case group) and 149 cases of health people(normal group) were selected from those elderly people who received physical examination in our hospital.The difference of blood lipid and uric acid between these two groups was analyzed.Results: The level of UA,Triglyceride(TG) and low density lipoprotein cholesterol(LDL-C) significantly increased comparing with the normal group.While the level of high density lipoprotein cholesterol(HDL-C) obviously decreased.Within case group,UA in male was higher than it in female and total cholesterol(TC) was lower than it in female.Conclusion: Metabolism of blood lipid and serum uric acid was abnormal in the elderly population with abnormal TSH level.Increase of TSH level might has relationship with metabolic diseases such as hyperlipidemia and hyperuricemia.


Biologists have long known that predators vary (modulate) their prey-capture behaviour in response to different prey. We propose an optimization model to predict when and why capture behaviour should vary. The predator's attack 'effort' (reflecting any unidimensional kinematic variable such as acceleration) determines both the probability of capturing the prey and the energetic cost of attack. The optimal capture effort then reflects a balance between the marginal benefit of greater success and the marginal cost of added energy outlay. Using this model, we explore how the optimum responds to variation in prey traits (evasiveness and energy value). The model predicts three different types of response to prey variation: (1) no modulation, (2) increased effort for more elusive prey and (3) decreased effort for more elusive or lower energy prey.


Healthcare and health information technology professionals are entrusted with patient data which, because of its personal nature, requires protection to ensure its confidentiality. To provide this protection, these professionals frequently look to commonly accepted technologies and methodologies to safeguard this data while at rest and in transit. One technology capable of providing this type of protection is encryption.


In recent years, there has been widespread interest and a large number of publications on the application of graph theory techniques into constructing and analyzing biologically-informed gene networks from cancer cell line data sets. Current research efforts have predominantly looked at an overall static, topological, representation of the network, and have not investigated the application of graph theoretical techniques to evolutionary investigations of cancer. A number of these studies have used graph theory metrics, such as degree, betweenness, and closeness centrality, to identify important hub genes in these networks. However, these have not fully investigated the importance of genes across the different stages of the disease. Previous human glioblastoma publications have identified four subtypes of glioblastoma in adults, based on signature genes. In one such publication, Verhaak et al. found that the subtypes correspond to a narrow median survival range, from 11.3 months for the most aggressive subtype, to 13.1 months for the least aggressive one. In this work, we present an evolutionary graph theory study of glioblastoma based on survival data categorization, confirming genes associated with different survival times identified using established graph theory metrics. The work is extending the application of graph theory approaches to evolutionary studies of cancer cell line data.


Partial differential equations describing the transient behavior of a non-adiabatic fixed-bed catalytic reactor are derived with a minimum of simplifying assumptions. These equations axe applied to predict the transient behavior of a reactor for the oxidation of SO2 taking into account the behavior of both the fluid stream and the associated catalyst pellets.

Stability analyses of the numerical methods of solving the equations are presented in great detail, as the methods of analyses available in the literature are inadequate for the complicated system of equations encountered. A special study is made of the effects on stability of various methods of handling the nonlinear source terms in the equations. Some of the schemes proposed in the literature are found to be subject to severe stability criteria.

A method of obtaining a rigorous solution is devised. The method is always stable, and the use of varying time increment size is allowable. A rigorous solution takes only a few minutes of computer time with an IBM-7094 computer.

To investigate the effects of various limiting assumptions, three problems are studied using the rigorous method and also with methods employing various assumptions. These problems are the start-up, the loss of cooling with subsequent restoration, and the response of the exit concentration to a sinusoidal concentration forcing function at the entrance. For the system investigated, the effects of using an "effectiveness factor" model, neglecting radial changes, and neglecting the axial diffusion and axial velocity variations are found to be not large. The neglecting of reverse reactions, or the use of an average effectiveness factor throughout the whole reactor causes significant errors.

A simplified method, which for the system studied, gives a reasonably good approximation to the true solution, is used to investigate problems in the optimization and control of the reactor. The frequency response of the exit temperature to a sinusoidal forcing upon the optimum wall temperature is found to be equivalent to that of a phase lag network frequently used in regulating systems.

Limitations to the applicability of the simplified method are discussed.


Oriented monolayers of an w-unsaturated fatty acid (1 7-octadecenoic acid, C 18: 1 17) have been prepared at the air-water interface and transferred to the surface of clean platinum foils. When the platinum-supported monolayer is exposed to dihydrogen, the olefinic group of the acid is hydrogenated. The rate of this reduction can be varied over a range of IO4 by changing the pH and metal ion concentration of the aqueous subphase on which the monolayer is prepared and the transfer pressure. The major influence on the rate is the metal ion incorporated into the monolayer: cadmium, an ion considered a cata- lyst poison, leads to slowly reduced monolayers; magnesium- and calcium-containing monolayers hydrogenate more rapidly; metal ion free monolayers reduce most rapidly. A secondary influence appears to be the rigidity of the film (as estimated by the compressibility of the original monolayer at the air-water interface). The rates of reduction of the supported unsaturated fatty acid monolayers parallel the rates of reduction of I-pentene vapor on similar monolayer-covered foils. These observations collectively suggest a qualitative picture for fatty acid monolayers supported on platinum as thin, viscous, liquid or liquid-crys- talline films. The study of the hydrogenation of supported, unsaturated monolayers provides an unexplored method for the ex- amination of the microscopic structure of these films, and suggests new approaches to the study of mechanisms of heterogene- ous hydrogenation.


There is a distinct theme running through this issue of Technology, Pedagogy and Education, in that all of the articles presented here are concerned with collaborative learning, albeit in different educational settings, and employing a range of learning technologies. Looking across these, what is striking (and this is a theme on which I have written previously in editorials) are the close and often complex links between digital technologies, pedagogical practices and discourses, research approaches and theoretical framings. We see in these articles accounts of technologies being creatively appropriated by teachers and learners; innovative research methods being used in support of classroom and online enquiries; and critical engagement with educational theory. Chandra and Mills discuss some of the factors that drive, enable and encourage the use of digital technologies, not simply to replicate or enhance but to transform teaching and learning environments, and they highlight the importance of ambitious, values-driven goals as well as collaboration between practitioners, stakeholders and educational leaders. Knight and Mercer's exploration of the means by which search engines can be used in classroom activities argues that such digital tools offer the greatest opportunities when they are seen not simply as information retrieval tools but when they are, instead, embedded within open-ended tasks supported by exploratory classroom talk. While Knight and Mercer's approach is to use close analysis of classroom talk, Du, Xu, and Fan employ entirely different research methods in their study of online help-seeking strategies. But, despite the different context and research approach, the importance of the pedagogical framing of tasks again emerges as being of central importance. The increasing use of wiki environments to support collaboration is then reflected in the articles by Biasutti and EL-Deghaidy, in their study of teachers developing primary school projects; and by Zheng, Niiya, and Warschauer, who highlight the importance of pedagogically informed learning design in their successful implementation. It is instructive to look across these articles (and others on the subject of wikis) in order to see how the 'malleability' of these technologies leads to the identification in different settings of diverse combinations of collaborative and pedagogical 'affordances'. Petty, Heafner, Farinde, and Plaisance, in their article, explore this kind of emergent awareness of the potential of technologies, and discuss (among other aspects) the patterns of collaboration and sometimes unexpected outcomes that emerged from sustained use of online environments to support reflective practice and professional learning. Finally, Park describes a study of patterns of 'legitimate peripheral participation' in online environments and explores the notion of 'interactivity' from participant perspectives. Once again, there is an emphasis on the importance of pedagogical framing of activities and the role of teachers and moderators in supporting online participation and collaboration. On a broader theme: the editors are interested in receiving suggestions for special issues for potential publication in 2016 and 2017. In the last few years we


verse species of fatty acyl chains. Remodeling of fatty acyl chains is supposed to be vital for the maintenance of membrane structure and function. However, the mechanism and physiological roles of phospholipid remodeling are not fully clarified. To elucidate the mechanism of phospholipid remodeling, it is effective to establish a system in which exogenous phospholipids or phospholipid analogs are incorporated into the cells and to monitor their metabolism in the cells. Phosphatidylethanolamine (PE) is one of the major and essential nonbilayer phospholipids and comprises ~20% of total phospholipids in eukaryotic cells (Daum et al., 1999; Storey et al., 2001). We have previously constructed a Saccharomyces cerevisiae strain, TKY12Ga, that is defective in phosphatidylserine (PS) decarboxylation by deletion of PSD1 and PSD2, and its PE synthesis can be controlled by the carbon source in the media through replacement of the promoter of ECT1, encoding CTP: phosphoethanolamine cytidylyltransferase, a key enzyme in PE synthesis through the Kennedy pathway, with the galactose-inducible and glucose-repressible GAL1 promoter (MinSeok et al., 1996; Deng, L., unpubl.). In galactose-containing minimal medium (SG medium), TKY12Ga grew in the presence of ethanolamine. In contrast, its growth was inhibited in the glucose-containing minimal medium (SD medium), even in the presence of ethanolamine. However, when didecanoyl PE (diC10PE) was added to the SD medium, TKY12Ga grew despite the inability to synthesize PE. Since the length of acyl chains in PE in yeast is mainly C14 to C18, it was presumed that the PE with short acyl chains was remodeled to those containing acyl chains of normal length to be a component in the biological membrane. Here, to obtain information on the utilization of exogenous PE in yeast, we isolated mutants defective in utilization of exogenous PE to support growth when the synthesis of PE was suppressed, and analyzed one of them. We mutagenized TKY12Ga with ethyl methanesulfonate (EMS) and isolated thirty-three mutants defective in growth on SD medium containing diC10PE from approximately 63,000 colonies. Among those, M25, M30, and M33 exhibited clear and stable phenotypes. These mutants did not grow in SD medium containing diC10PE, while they grew normally in SG medium containing ethanolamine at 30°C. In addition, M25 and M30 had the phenotype of temperature sensitivity in SG medium at 37°C (Fig. 2B–D, data not shown). However, the phenotypes of M30 and M33 were caused by multiple mutations, while that of M25 was by a single mutation (data not shown, see below). Therefore, M25 was chosen for further analysis. Isolation and characterization of a mutant defective in utilization of exogenous phosphatidylethanolamine in Saccharomyces cerevisiae


We consider Gaussian multiresolution (MR) models in which coarser, hidden variables serve to capture statistical dependencies among the finest scale variables. Tree-structured MR models have limited modeling capabilities, as variables at one scale are forced to be uncorrelated with each other conditioned on other scales. We propose a new class of Gaussian MR models that capture the residual correlations within each scale using sparse covariance structure. Our goal is to learn a tree-structured graphical model connecting variables across different scales, while at the same time learning sparse structure for the conditional covariance within each scale conditioned on other scales. This model leads to an efficient, new inference algorithm that is similar to multipole methods in computational physics.


The ion-optical properties of multisector electrostatic analyzcrs are studied. It is shown that by selecting fields in different sectors, it is possible to derive a zero congruence of the principal aberration coefficients at high dispersion. (tr-auth)


Reading the official Facebook page of one of my favorite history authors yesterday, I saw a pithy note about a "day of note." Ninety years ago this week, President Warren Harding dedicated the Lincoln Memorial at the west end of the National Mall in Washington, D.C. [excerpt]


The game design is a complex and huge task, it requires putting in a lot of manpower and material resources, and spends some time in order to create a beautiful and exquisite design of clever games. The design of three-dimensional terrain has become the focus of attention on this issue. This paper elaborates the theory about how to use the information which is got from the gray-scale map to establish a lively three dimensioned terrain. This paper designs and implements a demonstration to generate the effect of three-dimensional terrain.


In this article, we use laboratory methods to examine the effects of industrywide price regulation on industry structure and firm behavior. Such regulation, wherein prices are set with regard to an industry-wide aggregate performance measure, has bleen (and still is) widely used in a number of industries. We use the data generated in laboratory markets to examine two aspects of industry-wide regulation. First, does this type of regulation influence the formation and structure of e(luililrium, that is, does it affect the types of equilibria that appear? Second, are the resulting regulated oligopoly equilibria welfare-improving or welfare-impairing vis-a-vis ulnregulated oligopoly equilibria? In other words, does industry-wide regulation "help"? The answer to the first question is yes, while the answer to the second is a guarded no. Industry-wide regulation, wherein prices are set with regard to an industry-wide aggregate performance measure, has beenl (and still is) widely used. Examples include trucking, the airlines, natlural gas production, insurance, portions of the dairy industry, World War II industry price controls, taxicabs, and (in the near future) hospital cost reimbursement by


A number of male and female specimens were available for study. They were collected by my colleague Mr. J. McClelland who very kindly made them available for study. Description: The worm is very small with the largest diameter at the cephalic end and tapers down posteriorly and rather markedly so in the female worm (Fig. 4). The cuticle has fine striations. The bivalve buccal capsule has a number of longitudinal ridges of varying lengths. The number of these ridges are different for the male and female. The head is slightly tilted ventrad. There is a pair of tridents. The ventral trident is small and indistinctly branched. The dorsal trident is large and clearly trifid. The posterior part of the buccal capsule ends in six small projections (Fig. 1).


This article focuses on hyperspectral image (HSI) super-resolution that aims to fuse a low-spatial-resolution HSI and a high-spatial-resolution multispectral image to form a high-spatial-resolution HSI (HR-HSI). Existing deep learning-based approaches are mostly supervised that rely on a large number of labeled training samples, which is unrealistic. The commonly used model-based approaches are unsupervised and flexible but rely on handcrafted priors. Inspired by the specific properties of model, we make the first attempt to design a model-inspired deep network for HSI super-resolution in an unsupervised manner. This approach consists of an implicit autoencoder network built on the target HR-HSI that treats each pixel as an individual sample. The nonnegative matrix factorization (NMF) of the target HR-HSI is integrated into the autoencoder network, where the two NMF parts, spectral and spatial matrices, are treated as decoder parameters and hidden outputs, respectively. In the encoding stage, we present a pixelwise fusion model to estimate hidden outputs directly and then reformulate and unfold the model's algorithm to form the encoder network. With the specific architecture, the proposed network is similar to a manifold prior-based model and can be trained patch by patch rather than the entire images. Moreover, we propose an additional unsupervised network to estimate the point spread function and spectral response function. Experimental results conducted on both synthetic and real datasets demonstrate the effectiveness of the proposed approach.


The construction of network course resources is an important guarantee for the improvement of teaching quality in radio and television universities. At present,there exist some problems such as the lack of pertinence and personalization; not high quality and obvious lag; lack of interaction and independent learning resources. To solve the problems above,the principles of openness,learning,interaction and situation must be kept,and the strategies of changing the concept of course teachers to improve their quality,adhering to students-centered construction of network course resources and paying attention to the affectivity of network curriculum resources,etc.


We consider a torus T, that is, a compact surface with genus 1 and $\Omega = D^2 \times S^1$ topologically with $\partial\Omega = T$, where $D^2$ is the open unit disk and $S^1$ is the unit circle. Let $\omega = (x,y)$ denote the generic point on T. For a smooth immersion $u : T \to R^3$, we define the Dirichlet functional by $$ E(u) = \frac{2}{1} \int_{T} \nabla u^2 d\omega $$ and the volume functional by $$ V(u) = \frac{3}{1} \int_{T} u \cdot u_x \Lambda u_y d\omege $$.


Hemolytic uremic syndrome (HUS) due to Escherichia coli O157:H7 is a common cause of acute renal failure in children. We analyzed the immunological markers in these children and wish to realize the association between HUS and the immune system. The blood samples were collected on the first day of admission (acute phase), on the day of discharge when the patients' condition greatly improved (subacute phase) and one week later after discharge (convalescent phase). We quantitated ICAM-1(CD54), Fas (CD95), as well as activation markers (CD69, CD25) expression on their peripheral blood T cells and natural killer (NK) cells by flow cytometry. Ten age-matched healthy boys were included for comparison. We found that Fas and ICAM-1 expression on T cells in HUS patients during acute phase were greatly elevated compared to controls, both levels fell to control levels during convalescent phase. CD69 and CD25 expression on T cells, however, transiently increased then decreased thereafter. The elevated CD95 and CD69 expression on NK cells in HUS patients during acute phase also declined and were associated with clinical improvement. Thus, we demonstrated profound T and NK cells activation with enhanced ICAM-1 and Fas expression in acute HUS.


This paper summarizes some ideas about a new method for information retrieval and data description based on natural language features, which is applicable to both formatted and textual data.

The language's ability to express specific terms by noun phrases is particularly useful for describing information requests (queries) and data related to interdisciplinary fields, i.e. energy or environmental research. These fields are characterized by a fluctuating terminology, variety of different data and by information requests, which are difficult to predict. Therefore, it is expected that the proposed information retrieval and data description method will be more efficient than the currently used methods, which are based on Boolean expressions.


In manufacturing organizations, the largest and most important information systems are Manufacturing Resources Planning (MRPII) systems. These systems, in use in the US since the 1970s, have been implemented by an increasing number of Chinese companies. In this study, we evaluate the factors of influence and benefits realized by Chinese firms through MRPII. Based on survey responses from 93 companies in China, we analysed the factors that significantly influence the benefits of MRP, using the Additivity and Variance Stabilization (AVAS) and the Projection Pursuit Regression (PPR) methods. Applying AVAS and PPR methods established the functional relationship between the benefits achieved and the extent to which problems are encountered in implementation, the degree of involvement by different functional areas during the implementation and the number of functional modules used.


Hydrilla [ Hydrilla verticillata (L.f.) Royle] became established in the Atchafalaya River Basin (ARB) in south central Louisiana during the 1970s, and now dominates the submergent macrophyte community. We examined the potential effects of this shift in macrophyte composition on the distribution of phytomacrofauna by comparing water quality and macroinvertebrate assemblage structure in canopy and sub-canopy habitats at edge and interior locations within hydrilla and native coontail ( Ceratophyllum demersum L.) beds during the latter stages of the 2001 flood pulse. Both plant species exhibited similar water quality characteristics during the study, with significantly higher temperature, dissolved oxygen, and pH levels in canopy habitats. Principal components analysis of log-transformed macroinvertebrate densities identified four assemblages that together accounted for 63.5% of the variation in the density data. The GastropodaHydrachnida assemblage exhibited higher densities in coontail during May-June (declining river stages), and was more abundant at interior locations in both macrophyte beds during July (stable river stages). The Hemiptera-Amphipoda assemblage exhibited higher densities in the canopies of the two plants during both sampling periods, as did the Decapoda-Odonata assemblage in July. The Diptera-Coleoptera assemblage showed a similar trend in vertical distribution, as well as marginally higher densities in hydrilla beds. The continued spread of hydrilla throughout the ARB has reduced the diversity of macrophyte habitats available to phytophilous macroinvertebrates, and has resulted in pervasive hypoxia in the macrophyte sub-canopy over large portions of available littoral habitat, with significant impacts on the vertical distribution of littoral macroinvertebrates.


The Russian Soviet Federated Socialist Republic (RSFSR), which contains 51.5% of the USSR's population, has emerged as a key factor in the political and economic ferment that is undermining the very existence of the Soviet Union. The election of Boris Yeltsin as RSFSR president in June 1991 marked a decisive step in the decline of Mikhail Gorbachev's primacy and a new stage in the process of reform and democratization, the consequences of which we are only beginning to see. Though the RSFSR's population is over 80% Russian and over 85% Slavic, the republic confronts almost as many problems of ethnic and regional self‐assertion as the USSR as a whole. The 21 million non‐Slavs who live in the RSFSR occupy strategic border regions and economically critical areas. Most of them are jealous of their territorial autonomy, even though the system of union and autonomous republics and two kinds of autonomous districts has in many respects become anachronistic and illogical. As in the Transcaucasian republics to the...


Asymmetrical deformation zone of the snake rolling process results in complex metal flow and unknown edge of the deformation zone. In this study, three assumptions about the location of exit thickness appear and the exit thickness is calculated by those three assumptions. By comparing the exit thickness obtained by formulas and the finite element method, one formula with high accuracy is verified and the plastic deformation of the thick plate under several snake rolling conditions is obtained. The results show that through comparing the minimum thickness in different assumptions, the exit of the plastic deformation zone is located at the midpoint of the line between two work rolls' axis and the exit thickness is approximately equal to the length of the line which includes that midpoint and locates between the two work rolls in the vertical direction. Then with the increasing offset distance, the exit thickness increases and that leads to less deformation inside the plate. For maintaining the exit thickness equal to the preset value, an exit thickness compensation model is established according to the geometry of the deformation zone and verified by the results of simulations.


The Aharonov-Bohm (AB) scattering of charged particles by the magnetic field of an infinitely long and infinitely thin solenoid (magnetic string) in an absorbing medium is studied. We discuss the partial-wave approach to this problem and show that the standard partial-wave method can be adjusted to this case. The effect of absorption leads to oscillations of the AB cross section. Based on this we investigate the scattering of neutral atoms with induced electric dipole moments by a charge wire of finite radius, which is placed in a uniform magnetic field. The physical realistic and practically important case that all atoms that collide with the wire are totally absorbed at its surface is studied in detail. The dominating terms of the scattering amplitude are evaluated analytically for different physical constellations. The remaining terms are written in a form suitable for a numerical computation. We show that if the magnetic field is absent, the absorbing charged wire causes oscillations of the cross section. In the presence of the magnetic field the cross section increases and the dominating Aharonov-Bohm peak appears in the forward direction, suppressing the oscillations.

Abstract Europe boasts a large number of traditions and cultures which coexist in a relatively small space. However, despite this, different literary motifs and topics have been readapted and transformed into other different traditions. The Arthurian legend is a prime example of this. Whilst it originated in the British Isles, it rapidly expanded throughout the continent in many different cultural manifestations, from poetry to decorative arts, music to drama. The Arthurian legend acquired special importance in France, where Chrétien de Troyes's Erec et Enide gave it a courtly touch. The Welsh version of the story, Geraint ap Erbin, is less courtly than its French counterpart but keeps elements proper to the Welsh tradition. Thus, the Arthurian legend developed in different cultural traditions throughout the Middle Ages and it is the object of readaptations even today. Erec et Enide was recently rewritten and readapted into Spanish as a contemporary story focusing on modern-day problems. Manuel Vázquez Montalbán's Erec y Enide is an exceptional example of intercultural practice tailored to a culture (or even cultures) different from the original one in which it was composed. This article analyses the process of transferring and recreating the European medieval time and space of the French and Welsh texts into a Latin-American contemporary context, where brigands and thieves are substituted by henchmen and guerrillas and argues how translation can play a key role in the recreation of the medieval world in a contemporary setting.


and drilled stones to receive door bolts were found during the course of excavation. The rooms of the building were evidently very well fortified with sturdy doors, bars, and bolts. In room 20 some 25 whole and partial twisted opaque glass bracelets implied the presence of ladies in this area. Most of the other rooms yielded no bracelets at all. The bases of pottery bread ovens about 75 cms. in diameter in four different rooms and fragments of others indicated the preparation of quantities of food for the dwellers in the structure. The size of the rooms varied from 4.30 X 4.60 meters (room 22) and 5.50 X 5.90 meters (room 15) to a few smaller rooms like No. 24, c. 2.50 X 3.50 meters. The stratification of the T area, below the first level of Arabic, follows a similar pattern yielded in three previous seasons of excavation: Hellenistic material preceded by Iron Age levels. In the T area we found over 50 objects and in the A area over 200 pottery and stone objects, several dozen flints, a number of bronze pins and some iron objects, making a total of over 250 objects. The T area yielded over 43,900 sherds and the A area over 179,900, making a total of over 223,900. Over 2200 sherds were recorded. The 1956 staff was comprised of the writer and Mrs. Ruby Free as directors; Miss DeViolette Bernhardt and Miss Rosa Veal of Spartanburg, S. C.; Mr. and Mrs. Donald Brown, former Wheaton students; and Mr. Dwain Eckberg and Mr. Peter Gerard, Wheaton students. Area supervising was in charge of Mrs. Free, Mr. Brown, Mr. Eckberg, and Mr. Gerard; photography was in charge of Miss Bernhardt assisted by Miss Veal; recording and alternate supervising was shared by Mrs. Brown, Miss Bernhardt, and Miss Veal. Drafting in the A area was done by Mr. Gerard and in the T area by Mr. Eckberg, and pottery sorting and classification was in charge of the director, assisted by the other members of the staff. Helpful counsel was given by Mr. G. Lankester Harding, Director of the Department of Antiquities of the Hashemite Kingdom of Jordan, by Pere R. de Vaux of the 1cole Biblique, and by Father Sylvester Saller who has worked in later periods at Bethany and other sites. We plan a fifth season of excavation in 1957.

Forensic facial reconstruction is a small field within the area of forensic medicine. Forensic odontologists, forensic anthropologists and specific trained artists are performing facial reconstructions. This forensic technique can be useful when other identification methods fail. Since more than 100 years, scientists are trying to measure the thickness of the facial soft tissue layer, necessary to reconstruct a face. Measurements were performed both on living and dead persons. In the early years, probes and needles were used to measure the soft tissue thickness. Later on, both computers and ultrasonic equipment were introduced. Scientists faced some major problems though: the number of facial measuring points were very limited and the measurements were not accurate. Thus it was not possible to create a soft tissue database. On the other hand, there is a strong need for a reliable database of facial soft tissue thickness in the medical and anthropological forensic world. The aim of my research project was to develop an easy, efficient and reliable way to measure soft tissue thickness of the face. We used a small number of probands, within the same subcategory (age, ethnic). Holography was the perfect solution to reproduce the facial outline. In order to develop a new technique to do high precision facial soft tissue measurements, it is necessary to compare the holographic data to bone surface information. Computed Tomography can be a good source to provide these data. It is the first time a technique is developed to do high precision facial soft tissue thickness measurements, resulting in a dense field of measurement points.


Driving has become more and more popular with increasing populations and advances in the road vehicle industry. To drive legally, one requires to pass a few set of tests, depending on the type of drivers Licence code. The legal procedure to be followed is that an individual must go to a driving school and sit for such tests before a learners licence can be issued for the individual to practice driving skills on the road. The South African Traffic Departments are still using the old procedure of pen and paper to conduct the drivers learners licence examinations. As such, the prospective examiners are also practicing for the examinations using pen and paper procedures, a situation which results in lack of understanding of the techniques and a high failure rate of the tests. The pen and paper system is a bit outdated and cumbersome for the traffic department and it sometimes results in plenty of management errors being experienced. A solution to this problem is imminent and technical ideas from computer science technologies and expertise can lead to a breakthrough. This project focuses on the investigation, development and implementation of an electronic K53 system for practicing of the drivers learners licence examination. This research work is based on the e-K53 services in which users can access more accurate and quicker K53 services from the computerized e-K53 system. The purpose of this research work is to emulate the K53 manual that is currently used in South Africa to a computerized system and also allow users to prepare for their K53 examination using the e-K53 service. KeyWords—Learners Licence; Drivers Licence; Road Traffic; Examinations Tests; e-K53 Service; vehicles and Motorcycles Examination, e-K53Service.


In order to meet the need of modernization, according to the reality of our party, we put forward concept of development-serving people as foundation, setting up all-side, coordinated, sustainable develogment. It is founded on people that this science development concept and has embodied with together rich unification, the unification that has embodied assurance economic law and natural law has embodied the unification of 4 virtuous circles, has embodied the unification of quantity and the quality of economic development.


The BEF on the radial distribution line refers to a class of ground faults in which the load-side power line only is grounded, with the distribution line broken into two parts, the source-side and the load-side. Because its mechanism is remarkably different from that of other earth faults, the fault current is very low, and then difficult to detect the BEF. Thus, it is necessary to analyze its properties and to find an appropriate method that can economically protect the BEF of nonautomation area in the substation. As a result of analyzing the BEF data obtained by the RTDS, EMTP simulation, and the field test data of ETSA, we believe that it is the dominant factor in distinguishing the BEF from normal conditions by a criterion value that is appropriately handled from the zero-sequence current. Thus, with this criterion value, a BEF detecting algorithm is constructed which measures the variations of the zero-sequence current and processes then properly so as to make the fault decision. To prove the accuracy of this algorithm, it is compared with the field test data of ETSA under various conditions. The results show that the proposed algorithm is accurate.


Adenomyosis has only been reported in one patient with mosaic Turner syndrome. We report a case of mosaic Turner syndrome in a patient who suffered from hypermenorrhoea and severe anaemia due to adenomyosis. A 40-year-old woman visited us desiring to conceive. The patient had got pregnant twice, but they resulted in spontaneous abortion. After her third miscarriage, chromosomal banding was performed and the patient was found to have a mosaic chromosome complement (45,X [9]/46,XX [21]). We report an extremely rare case of a patient with mosaic Turner syndrome who presented with typical clinical symptoms of adenomyosis.

The number of children prenatally or after birth diagnosed with a disease with no prevent radical treatment options in Latvia and worldwide constantly increases. Pediatric palliative care in Latvia is organized in the form of a home hospice care model. It is instrumental to establish the level of patients' satisfaction with the provided care and treatment services. The objective of the study is to evaluate patient satisfaction with care and treatment services under the offered pediatric palliative care model. The study sample comprises 153 parents with children receiving palliative care services. The study is based on the quantitative research method: patient satisfaction survey. The parental satisfaction was measured in six subcategories: networking and collaboration, follow-up care, funding, access, clinical capacity building and outreach. According to the outcomes of the study, the level of satisfaction with the provided treatment and care services under the hospice palliative care model is average. The lowest score was given to collaboration and access categories, whereas the highest score was awarded for the continuity (follow-up) of care and funding.

ALICE is the experiment specifically designed to study the Quark-Gluon Plasma (QGP) in heavy-ion collisions at the CERN LHC. The ALICE detector will be upgraded during the Long Shutdown 2, planned for 2019-2020, in order to cope with the maximum interaction rate of 50 kHz of Pb-Pb collisions foreseen for Runs 3 and 4. The ambitious programme of high-precision measurements, expected for muon physics after 2020, requires an upgrade of the frontend and readout electronics of the existing Muon Spectrometer. This concerns the Cathode Pad Chambers (CPC) used for tracking and the Resistive Plate Chambers (RPC) used for triggering and for muon identification. The Muon Forward Tracker (MFT), an internal tracker added in front of the front absorber of the existing Muon Spectrometer, is also part of the ALICE detector upgrade programme. It is based on an assembly of circular planes made of Monolithic Active Pixel Sensors (MAPS), covering the pseudorapidity range 2.5 < η < 3.6. The MFT will improve present measurements and enable new ones. A selection of results from physics performance studies will be presented, together with an overview of the technical aspects of the upgrade project.


The WHO classification of lymphoid neoplasms was published in 2001, then was updated in 2008, and will be evolving in the future. This classification is based on the disease discovery and accurate description by pathologists beyond the heterogeneity in the geographical distribution of the disease entities. It is now increasingly recognized that some peculiar T and NK cell lymphomas are largely prevalent in the East Asia as mostly represented by adult T-cell leukemia/lymphoma, NK/T-cell lymphoma, intestinal T-cell lymphoma, and chronic active EBV infection. They are associated with viruses in some and generally have a broad clinicopathologic spectrum spanning from the precursor lesion to overt lymphoma, often posing the differential diagnostic problems to the pathologists. In addition, we are now facing the newly standing-up diseases. They always request us to refine the disease definitions and concepts more accurately and to innovate our therapeutic approaches. These processes simultaneously lead us to further understanding of the immunology and biology in the human beings. This slide seminar will be operated by the leading hematopathologists in Asia: Professors Koichi Ohshima, John K.C. Chan, Young-Hyeh Ko, Shih-Sung Chuang, and Tawatchai Pongpruttipan to address the new diseases, findings, and ideas since the 2008 WHO publication.


A tubular photobioreactor, based on an external loop airlift, has been used for outdoor continuous culture of the microalga Phaeodactylum tricornutum UTEX 640, rich in eicosapentaenoic acid (EPA). The effect of dilution rate on the biomass productivity and EPA production were examined. A maximum biomass productivity of 2.57 g⋅day−1⋅litre−1 was reached at an optimum cellular density of 7.12 g⋅litre−1. At around 2times1017 quanta⋅s−1⋅cm‐2 photosynthetic activity seemed to become light‐saturated. As the dilution rate increased, the fatty acid profile in biomass dry weight changed and EPA became the major fatty acid. We believe that this outdoor production of EPA from this species is the highest ever obtained (47.8 mg⋅day−1⋅litre‐1). On the basis of these data it would seem advisable to use tubular photobioreactor technology for the production of very valuable microalgal products

CAN is probably the most successful bus in the automotive domain, especially, due to its low cost and robustness. However, with increasing connectivity, there is a need to encrypt data to avoid attacks such as Spoofing and Sniffing. This ends up exposing CAN's severe limitations. In particular, each encrypted message requires sending two frames due to its restrictive payload in CAN. Moreover, each frame of an encrypted message undergoes a separate arbitration process which negatively impacts timing and makes it difficult to meet deadlines. In this paper, to work around this problem, we propose a technique that consists in assigning different priorities to encrypted CAN frames so as to compensate for increased delay. The basic idea is that, once the first frame of an encrypted CAN message wins arbitration, its second frame will always win arbitration within a specified scope and can be sent with lesser delay. We have conducted experiments on real hardware and performed extensive simulations indicating that the proposed technique reduces transmission delay to one half or even one third compared with the standard approach allowing us to still meet typical automotive deadlines on an encrypted CAN bus.


The present paper presents how the flood directive has been implemented on the Seine and coastal rivers of Normandy basin. It presents the various steps and details the elaboration of the basin flood risk management plan (PGRI). Though out of the scope of the present paper, the new responsibility in term of flood prevention given to local authorities will be briefly introduced and discussed with reference to the implementation of the flood directive.


The existing techniques for shot partitioning either process each shot boundary independently or proceed sequentially. The sequential process assumes the last shot boundary is correctly detected and utilizes the shot length distribution to adapt the threshold for detecting the next boundary. These techniques are only locally optimal and suffer from the strong assumption about the correct detection of the last boundary. Addressing these fundamental issues, in this paper, we aim to find the global optimal shot partitioning by utilizing Bayesian principles to model the probability of a particular video partition being the shot partition. A computationally efficient algorithm based on dynamic programming is then formulated. The experimental results on a large movie set show that our algorithm performs consistently better than the best adaptive-thresholding technique commonly used for the task


Central Solenoid (CS) and Toroidal Field (TF) model coils have been developed in order to establish technologies required to the ITER magnets. All of the development goals have been achieved, including the operation at 13 T, 46 kA and pulsed charging at 1.2 T/s in the CS model coil and the stable operation at 10 T, 80 kA under the ITER relevant stress condition in the TF model coil. Based on these results, further activities are now being performed, in extensive collaboration with industry, to optimize coil designs, to improve performances and to mitigate technical risks during the manufacture of the ITER magnets. One of the activities is to establish production capability of Nb3Sn strands having higher critical current density which was redesigned based on the detailed assessment of the conductor performance in the model coil experiments. Strands fulfilling the ITER requirement have successfully been obtained. Another set of activities are full scale manufacturing demonstrations on jacket material for CS and structural materials for TF coil. So far, large forged blocks of JJ1 and ST316LN and thick hot rolled plates of ST316LN were successfully produced as a trial fabrication for the TF coil structures. Experience in the TF model coil indicated a need to improve manufacturing processes for radial plate and a significant progress has also been obtained in this area. Achievements from these activities will provide a firm technical basis for ITER magnet construction including that for industry


The current study was applied in two successive seasons (2019 and 2020) with a view of keeping fruit quality, water content and reducing the chilling injury symptoms and browning of ripe pomegranate cv. 116 (which is considered one of the promising exportation pomegranate cultivars in Egypt in the last years) during cold storage at 5°C and 90% RH for 56 days followed by simulated shelf life at 20°C for 14 days. All conducted coating treatments including; beeswax at 5 and 10%, 1 and 2% of chitosan, 10 and 20% of paraffin, and Arabic gum at 5 and 10% were effective in maintaining fruit quality compared with control (uncoated fruits). Chitosan at 2% significantly maintained fruit quality, firmness, visual appearance, husk color (L value and a* value), ascorbic acid, and anthocyanin, also it reduced the browning incidence and decay percentage. Paraffin at 20% and beeswax at 10% were effective in maintaining fruit water content, in addition to significant preservation of husk distention was observed by using paraffin at 20%, whilst chitosan at 1 and 2% regulated activity of peroxides enzyme. Furthermore, using Arabic gum at 5% was the most effective significantly in the stability of fruit respiration rate and total soluble solids content compared with control.


Definitions of whole grains vary depending on context and purpose, creating a gap between the findings of nutrition science and the dietary guidance consumers receive. A review of the scientific literature was conducted to evaluate the impact of these grain components on adiposity measures. MEDLINE was used to search the scientific literature for relevant studies. Additional studies were identified by bibliographic searches for relevant articles. Editorials, reviews, and studies published in languages other than English were excluded. Intakes of cereal fiber, bran, mixtures of whole grain and bran, and whole grains were generally inversely associated with adiposity measures; cereal fiber intake had the most consistent associations. The association between whole grains and weight gain reduction was attenuated after adjustments for fiber and micronutrients. Most whole grain analyses included ~25% bran in the whole grains food category. Thus, most studies reported as providing evidence on whole grains were substantially confounded by including bran containing foods. The small number of studies that reported effects from whole grain foods alone showed inconsistent effects on body weight measures. The data suggest that bran and cereal fiber are active components of whole grains.


Studs and vias are two basic structures in multilevel interconnection. For higher device density and better speed performance inl VLSI technology, the stud or via aspect ratio has to be increased from the present value of 0.5 to about 2.0. The high aspect ratio would raise a reliability concern of current crowding and local heating. In this study, finite element method has been used to calculate the distributions of current density and temperature in multilevel interconnection with studs and vias. The results show that current density peaks in the stud increase with decreasing stud width and thus with increasing aspect ratio. The rate of increase is faster for submicron lines than for wider lines. Current crowding in the via is found to increase with increasing step angle due to the thining down of the step cross-section. The results also indicate that current crowding in the 60° via step region gives rise to a hot spot due to Joule heating. Results of these calculations provide a general approach to optimize the aspect ratio and geometries of stud and via structures for minimal current crowding and local heating in multilevel interconnection.

Although human NK cells lyse a wide spectrum of target cells, the precise target structure recognized by NK cells has not yet been elucidated. In order to define a possible relationship between gangliosides on human target cells and susceptibility to NK lysis, 14 human leukemia and lymphoma cell lines were studied. A significant correlation was observed between the quantity of ganglioside GM2 on the target cells and sensitivity to NK lysis. In a single‐cell binding assay purified GM2 specifically inhibited human NK cell binding to K562 target cells while other gangliosides did not inhibit binding. The competitive inhibition of NK cells by GM2 was restricted to the source of tissue from which GM2 was isolated. These results indicate that GM2 is a strong candidate as a target recognition structure for human NK cells.


To efficiently remove heavy metals from contaminated soils around an abandoned mine, new magnetically modified alginic acid and XYZ samples were prepared. The Kahak mine, which is located in Kwang-Myung City in Korea, was chosen to provide a model contaminated soil. Among the heavy metals in this contaminated soil, the concentration of Zn 2+ was the highest (ca. 500 mg/L); the concentrations of Pb 2+ , Cu 2+ , and Cd 2+ were 300, 45, and 5 mg/L, respectively. In the case of alginic acid containing carboxyl groups only, the removal efficiencies of Pb 2+ and Cu 2+ were high (95 and 85 %, respectively), but those of Cd 2+ and Zn 2+ were low (ca. 40 %). Meanwhile, most of these heavy metals could be completely removed when the XYZ adsorbent, including amine and xanthate functional groups, was used. The sorption mechanism involves chelating the heavy metals to S and N atoms of a variety of functional groups. Heavy metals could be removed within 30 sec with no re-elution. Therefore, this process seems to be a very safe method for removing heavy metals from the contaminated soils of the Kahak mine.
