Let G be a connected complex reductive linear algebraic group, and let K⊂G be a maximal compact subgroup. The Lie algebra of K is denoted by k. A holomorphic Hermitian principal G-bundle is a pair of the form (E G ,E K ), where E G is a holomorphic principal G-bundle and E K ⊂E G is a C ∞ -reduction of structure group to K. Two holomorphic Hermitian principal G-bundles (E G ,E K ) and (E' G ,E' K ) are called holomorphically isometric if there is a holomorphic isomorphism of the principal G-bundle E G with E' G which takes E K to E' K . We consider all holomorphic Hermitian principal G-bundles (E G ,E K ) over the upper half-plane H such that the pullback of (E G ,E K ) by each holomorphic automorphism of H is holomorphically isometric to (E G ,E K ) itself. We prove that the isomorphism classes of such pairs are parameterized by the equivalence classes of pairs of the form (χ,A), where χ:R→K is a homomorphism, and A∈k⊗RC such that [A,dχ(1)]=2√ -1 . A. (Here d X :R→k is the homomorphism of Lie algebras associated to χ.) Two such pairs (χ,A) and (χ',A') are called equivalent if there is an element g 0 ∈K such that χ'=Ad(g 0 )°χ and A'=Ad(g 0 )(A).


What happens to the legitimacy of the Scandinavian model of the welfare state within the context of post-industrial development and the growth of the middle classes? Theoretically, two rival hypotheses can be posed. According to the saturation approach, the legitimation of the welfare state collapses. As general welfare increases, people adopt more individualistic stances toward the welfare state. By contrast, the irreversibility theory of the welfare state suggests that the legitimacy of the welfare state even improves as more people are employed by the welfare state and as all citizens are covered by its services. These hypotheses are tested empirically by using recent Finnish opinion survey data and by employing structural equation methods. At least in Finland, the irreversibility approach clearly gets more support than the rival saturation hypothesis. The results show that the middle classes are neither overly individualist nor critical of the Finnish welfare state.


Background measurements were made with twenty-eight high purity germanium detectors (HPGe) on the Mobil Imaging and Spectroscopic Threat Identification (MISTI) system across a portion of the Continental United States (CONUS). MISTI was developed by the Naval Research Laboratory(NRL) for the Domestic Nuclear Detection Office (DNDO) as part of the Stand off Radiation Detection Systems (SORDS) program. Measurements were made from Washington D.C. to Pocatello, Idaho, during the dates of Mar 25, 2011 to Mar 28, 2011. The effect of variable backgrounds on detection sensitivities will be discussed. An opportunity was also afforded to measure the radioactive materials released from Japan's Fukushima I Nuclear Plant across a significant portion of CONUS. A description of the instrument and results are discussed.


Behavior of Baetis bicaudatus (Ephemeroptera; Baetidae) was video taped in a western Colorado, USA stream to identify the specific stimuli eliciting noncontact responses to predatory stoneflies (Kogotus modestus; Plecoptera; Perlodidae). In situ behavioral and feeding trial experiments were also conducted to assess the effect of removal of Baetis cerci on these responses to predators, on measured reactive distances, and on the vulnerability of Baetis to stonefly predation. Predatory stimuli tested included live stoneflies (tethered and untethered), stonefly models (plasticized), excised fresh stonefly antennae, and wires. Intact Baetis primarily turned their cerci (tail curl behavior) with similar frequencies toward live or model stoneflies that were between 1 and 2 cm downstream, and primarily moved when stoneflies were within 1 cm even before contact. Removal of Baetis' cerci reduced the frequency of tail curl responses and the reactive distance, but increased the frequency of movement responses to noncontact with Kogotus. Neither intact nor cerciless Baetis showed much response to Kogotus antennae and wires. These results suggest that stimuli associated with the whole stonefly, such as visual or more probably hydrodynamic cues, cause Baetis tail curl behavior. However, movement behavior was uniformly high after contact with all predator treatments, and the pattern of movement (swim, drift or crawl) varied with predator stimulus, suggesting that Baetis can discriminate live or model Kogotus, Kogotus antennae, and wires using chemotactile or tactile cues. Removal of Baetis cerci resulted in increased encounter rates (contact) with live, untethered Kogotus, higher capture success, and greater predation rates than on intact Baetis. When touched by all predator treatments, Baetis usually swam, a behavior that stimulates stonefly attacks, but after noncontact tail curl responses, Baetis most often remained stationary. Thus, cerci were apparently effective as an early warning system, enabling Baetis to detect Kogotus before contact, thereby reducing the incidence of dangerous swimming escape behavior, and the susceptibility to predation.


This paper studies the firm's optimal preemption timing and its perfect Bayesian investment equilibrium. The research shows that the optimal investment is between NPV threshold and the monopoly's optimal strategy; the value of real options can be eroded by competition white the introduction of incomplete information weakens the erosion, which indicates waiting is valuable even in very drastic preemption competition.


By using SWOT analysis,this paper analyses the advantages,weaknesses,opportunities and threats in intra-county credit markets of Agricultural Bank of China.The result shows that,in the mid-long term,Agricultural Bank of China should adopt differentiation of management strategy in intra-county credit markets.Therefore,in order to foster strengths and circumvent weaknesses and strengthen sustainable development capacity of intra-county branches,Agricultural Bank of China should deepen the cooperation with new-type rural financial institutions by offering wholesale loans,engaging principal agents and sharing resources.Based on the above analysis,this paper finally proposes several relevant suggestions on how to fulfil the combination strategies in intra-county credit markets for Agricultural Bank of China.


Abstract In order to explore the relationship between moral reasoning and conduct, 38 Grade Six students, deemed by their teachers to display 'delinquent' or 'non‐delinquent' characteristics, were administered Kohlberg's Moral Judgment Instrument (Kohlberg et al., 1973) and an IQ test. Subjects were then randomly assigned to three treatment groups: a) experimental‐‐discussion of moral dilemmas; b) placebo‐‐social studies games; c) control. A month later Kohlberg's instrument was readministered. Findings indicated that 'delinquents' and 'non‐delinquents' differed significantly (p = .001) on moral reasoning scores at both testing times. There was no statistically significant treatment effect (p = .06). Intelligence quotient was significantly and positively related to moral reasoning for 'non‐delinquents', but not for 'delinquents'.


This study aims to explore an analysis of the effects of using the TikTok application as a new learning model in the arts and culture sector during the Covid-19 Pandemic. The author observes that there is a considerable change in behavior among the community, especially the millennial generation in the use of technology as a bridge for online learning, namely the increasing interest of millennials in using the TikTok application lately. The research study on this occasion was carried out with a quantitative approach, where data collection was taken using a questionnaire technique. The measurement technique uses a Likert scale from a range of 1-5. The object of the research was focused on junior high school students, which was carried out using the Random Sampling Technique in which 103 participants were recorded. The Research Question is focused on exploring the relationship of this application with a new learning approach to arts and culture. The results showed that as many as 62.1% of respondents strongly agreed to help adjust traditional dance moves, 70.9% helped memorize movement choreography, 68% helped to recognize modern dance, and 57.3% agreed that this application helps understand cultural arts learning.


The Alto Tibiri is a pegmatite body located in the southern region of the Rio Grande do Norte, in Parelhas city, geologically inserted in the Borborema Pegmatite Province and occur intruding the mica schists of the Seridó Formation. Currently, both mica and feldspar are commercially exploited in this pegmatite body. In the field missions, 39 outcrops were described, in each one the main texture and mineralogical aspects of the outcropping rock were described. The geological mapping has allowed us to distinguish two types of schists, based on content and size of the mineral phases. There is a garnet rich schists and other with a relevant cordierite content. The studied region shows narrow pegmatite dykes, composed of quartz, feldspar, muscovite and/or biotite and black tourmaline, these dikes were classified as homogeneous. It's possible to observe in Alto Tibiri a welldefined mineral zoning, as follows: i) border area, marked by the abundance of muscovite; ii) Zone II, composed of quartz, feldspar and mica, in which the main mineral resources occur (tantalite, spodumene, apatite, etc.) and iii) quartz pockets. The observed mineral zoning is similar to that described as mixed traditional pegmatite bodies.


The Supreme Court's recent opinion in Quanta Computer, Inc. v. LG Electronics, Inc. notably affirmed the exhaustibility of method patents. Yet the Quanta decision also introduces other, more subtle elements into patent exhaustion jurisprudence. First, the Court conflates two formerly independent preconditions of patent exhaustion, namely (1) the utility of the unfinished article and (2) the purpose of the exhausting sale. Second, the Court purports to relax the standard of alternate uses for the patented article, from merely possible alternate uses to reasonable ones. These changes have the potential to shift the balance of power in patent litigation significantly toward alleged infringers.


This chapter analyzes a specific form of contemporary art, the one that is created and exhibited in the community, conceived and visualized outside of the art market and independent of the agenda of creative industries and art galleries. The motivation, purpose and meaning of such art practices, for both the artists and the community, are discussed and examples of community art projects are analyzed in order to understand how art became, in this first quarter of the twenty-first century, such a valued collective asset, so accessible and present in the daily life of the common man. Two Portuguese case studies have been chosen as illustrations: the first one is a funding programme of projects focussed on artistic practices for inclusion (the PARTIS programme, by the Calouste Gulbenkian Foundation) and the second is a self-financed and self-curated artistic collective, Pescada no 5.


Lecture
Corticosteroids and antimetabolites, with the addition of calcineurin inhibitors (CNIs) a decade later, were the first immunosuppressive agents used among liver transplantation (LT) recipients. They are currently among the most common choices for immunosuppression (IS). Development of the IS after LT allow nowadays to obtain remarkable results. However, lifelong IS is associated with severe adverse events like infectious, cardiovascular, renal, metabolic, and oncologic complications that leads to major morbidity and mortality. Consequently, there is ongoing studies for effective immunosuppressive regimens with acceptable side effects. Newer protocols include combinations of drugs with different modes of action and toxicity profiles. The two prominent approaches are as follows: the upfront strategy in which the immunosuppressive drugs were selected with respect to patient's pretransplant and/or intraoperative risk factors, and the downstream strategy in which a standard therapy is given and changed according to its toxicity and efficacy during the course of therapy. Corticosteroids are employed in immediate and early postoperative period. Although they have a pronounced side effect profile, CNIs are still the backbone of early and late phase immunosuppressive regimens because of their proved efficacy. Antimetabolites are frequent choices for steroid and/or CNI-sparing strategies. Studies also have established a role for mammalian target of rapamycin (mTOR) inhibitors in specific groups of recipients. Biologic agents are a hot topic of interest and made their way into current strategies for induction. IS withdrawal seems feasible in very long-term survivors (> 10 years), but is not associated with reversal of IS-related complications. Awaiting novel immunosuppressive drug categories, integration of upfront strategies with the aim to reduce CNI-exposure and a low threshold for adjustment in the posttransplant course are advisable to improve long-term outcomes of LT.


The purpose of this study is to identify the relationship among injury prevention practices, health locus of control, and response patterns to HLOC of the elderly. Subjects were 121 healthy elderly. The data had been collected from November 5 to 18 in 2001 and analyzed with descriptive statistics, t-test, ANOVA, Pearson's correlation and stepwise multiple regression. Health locus of control and injury prevention practices were measured by using MHLC scale and an instrument created by the researcher on the basis of the results of literature review respectively. The results of this study were as follows: The mean score of injury prevention practices was 2.80 and the mean scores for the health locus of control were internal health locus of control : 17.25, external health locus of control : 16.09, and chance health locus of control : 14.26. The response patterns of the HLOC identified were six types; pure internal, pure powerful others, pure chance, double external, believers in control, and complex control. The 'pure internal' was the largest group(35.5%), and the 'believers in control' was the next(31.4%). The relationship between internal health locus of control and the injury prevention practices of the elderly revealed a significant correlation(r=.215, p=.018). The relationship between external health locus of control and the injury prevention practices of the elderly revealed a significant correlation (r= .208, p=.022). There was significant difference between response patterns of the health locus of control and injury prevention practices(F=2.393, p=.042). There were significant differences between injury prevention practices and general characteristic factors, which were education, family type, administration of medication, injury experience, ADL, and self-directed search for health information. Self-directed search for health information, injury experience, and education explained 16.7% of the variance for injury prevention practices. The above results may be used as the basic data for seeking more efficient way of improving safety of the elderly.


The study of radiation saturation length and saturation power sensitivity to beam main parameters (emittance, energy spread and peak current) at the entrance of the undulator section of PSI-XFEL project is presented. The comparative analysis of the SASE FEL performance with external and natural focusing in undulator section is given. INTRODUCTION The PSI-XFEL project [1,2] is aimed to obtain the high brightness coherent radiation in the 0.1-7 nm wavelength range. After injector, the beam is accelerated to the maximum energy of 5.8 GeV. Two bunch compressor sections are foreseen to compress the bunch rms length down to 8.8 μm. The compressed electron beam with 2.7 kA peak current is delivered at different energies 2.1, 3.4 and 5.8 GeV to three undulator sections Athos, Porthos and Aramis to produce SASE FEL (Fig.1). In addition the High Gain Harmonic Generation (HGHG) D'Artagnan beamline at electron energies of 2.1–3.4 GeV seeded with 12nm wavelength external laser is planned. Aramis undulator will produce linearly polarized FEL radiation with wavelengths starting of 0.1 nm to 0.7nm utilizing electron beam with the energy that can be varied up to 5.8 GeV. Porthos and Athos undulators' radiation fundamental wavelengths are also tuneable within the range of 0.7 – 7.0 nm. They can produce radiation with both linear and circular polarization. The undulator systems should be compact (~70 m) to fit the area anticipated for the construction of the PSIXFEL facility. In this paper the calculations are based on bunch charge 0.2 nC and 0.4 nm normalized beam emittance, which can be expected from start-end simulations. The undulator sections with different undulator K values (Table 1) are composed of the similar cells with the undulator segment length of 4m and FODO period length of 9.4 m. Figure 1: Schematic layout of PSI-XFEL undulator lines. The main design parameters of the PSI XFEL project are presented in Table 1. Table 1: PSI-XFEL main design parameters Aramis Porthos Athos Beam Energy [Gev] 5.8 2.1/3.4 2.1/3.4 Wavelength (nm) 0.1-0.7 0.7-2.8 /1.8-7 0.7-2.8 /1.8-7 Undulator K Value 1.2 1-3.2 1-3.2 Period [mm] 15 40 40 Undulator type Planar/invac. APPLE II APPLEII Two three-dimensional simulation codes SIMPLEX [3] and GENESIS [4] have been applied to study the FEL performance sensitivity to beam main parameters and injection jitter. The SASE FEL performance without external focusing in undulator beamline is studied. FEL SENSITIVITY TO BEAM PARAMETERS In the real accelerator the beam main parameters (emittance, energy spread and peak current) differ from the design values due to various types of machine components imperfections. The tolerable beam main parameters budget is an important issue of the facility design study to provide the reliable facility operation. In this section we present the results of our study for the SASE FEL performance sensitivity (saturation length st L and saturation power st P ) to beam main parameters in Athos, Porthos and Aramis undulator sections. Fig.2 presents the SASE FEL power growth curve for beam design parameters in Aramis undulator section. At radiation wavelength of 0.1 nm, the saturation length is 60.4m and the saturation power is 6.15 GW. Figure 2: The Aramis SASE FEL power growth curve for beam design parameters. _________________________________________ firstname.lastname@example.com TU5RFP054 Proceedings of PAC09, Vancouver, BC, Canada 1208 Light Sources and FELs A06 Free Electron Lasers By means of the SIMPLEX and GENESIS simulations we investigated the behavior of the FEL performance parameters (saturation length and saturation power) when the electron beam normalized emittance varies from 0.36 to 0.8mm-mrad. In Figure 3 the dependence of saturation length and power on electron beam emittance for Aramis are presented. It turned out that saturation length increases by 75% and saturation power decreases by about 75% compared with the design values for Aramis (Fig. 3). Figure 3: The normalized saturation length (Ls) and power (Ps) dependence on the beam emittance. The complete results for Aramis, Porthos and Athos undulators are presented in Table 2. The pictures for all the three SASE chains are similar. Table 2: Change of saturation length and power when emittance varies from 0.36 to 0.8mm-mrad Undulator Wavelength [nm] Sat.

Fog layer sits between cloud layer and edge-layer and responsible for selection of edge-nodes to process cloud tasks. Fog devices manage routers, gateways and other scheduling components, which makes them highly vulnerable to security attacks. Attackers inject malicious packets fog-server, middleware or sensing layers which causes a wide variety of attacks. These attacks include node capturing, signal jamming, node outage, authorization, selective forwarding, data disclosure etc. To remove these attacks, wide variety of solutions are proposed by researchers, which include authorization, cryptography, error correction, firewall, broadcast authentication, selective disclosure etc. Moreover, these solutions vary with respect to privacy and security quality metrics, attack prevention capabilities and deployment quality of service (QoS). Thus, testing and deployment of these solutions is time consuming, requires additional manpower for performance validation. Hence fog deployments require larger time-to-market and are costly than their corresponding cloud deployments. In order to reduce the time for testing and validation of these resilience techniques, this text reviews various fog security & privacy preservation models and discusses their nuances, advantages, limitations and future research scopes. Furthermore it also performs a detailed performance comparison between the reviewed models, which assists in selecting best possible approach for a given application scenario. This text also recommends various fusion based approaches that can be applied to existing security and privacy models in order to further improve their performance. These approaches include hybridization, selective augmentation and Q-learning based models that assist in improving efficiency of encryption, privacy preservation, while maintaining high QoS levels.


To unify the motivating principles behind Max-Sum and Single-Linkage clustering, we consider an axiomatic approach to the theory of Clustering. We discuss abstract properties of clustering functions, following the framework of Kleinberg, [7]. By relaxing one of Kleinberg's clustering axioms, we sidestep his impossibility result and arrive at a consistent set of axioms. We suggest to extend these axioms, aiming to provide an axiomatic taxonomy of clustering paradigms. Such a taxonomy should provide users some guidance concerning the choice of the appropriate clustering paradigm for a given task. The main result of this paper is a set of abstract properties that characterize the Max-Sum and Single-Linkage clustering functions. These functions have been traditionally treated separately, as the principles motivating their use have never been unified. In the current paper we provide alternative axiomatic definitions for Max-Sum and Single-Linkage which sheds light on their common underlying principles and will guide the user to decide which is appropriate for a particular task, if either of them.


Because of the preconception that they are doomed to early failure, the use of rotating hinges in total knee arthroplasty (TKA) remains a controversial topic. We share our experience of more than 100 patients undergoing TKA using a rotating hinge. As we had in mind the single purpose of allaying fears of early failure, this was a fairly simple study, using revision as a concrete endpoint. We discuss indications, contra-indications and some examples. With our study showing a 93.6% survivorship rate at a mean of 4.8 years, we conclude that the rotating hinge has a definite place in TKA.


Molybdenum K-edge X-ray absorption and Mo(V) electron paramagentic resonance (EPR) spectroscopies have been used to probe the metal coordination in oxidized and reduced forms of both wild-type and a site-directed mutant of Rhodobacter sphaeroides dimethyl sulfoxide (DMSO) reductase. We confirm our earlier findings (George, G. N.; Hilton, J.; Rajagopalan, K. V. J. Am. Chem. Soc. 1996, 118, 1113−1117) that the molybdenum site of the oxidized Mo(VI) enzyme possesses one terminal oxygen ligand (MoO) at 1.68 A, four thiolate ligands at 2.44 A, and one oxygen at 1.92 A and that the dithionite-reduced Mo(IV) enzyme possesses a desoxo species with three or four Mo−S at 2.33 A and two different Mo−O ligands at 2.16 and 1.92 A. Mo(V) EPR indicates the presence of one exchangeable oxygen ligand, most likely an Mo−OH, in the signal-giving species, probably originating from the MoO of the oxidized enzyme (Em8.5(IV/V) = +37 mV, Em8.5(V/VI) = +83 mV). The addition of dimethyl sulfide, in the reverse of the physiological...


Configuration of the computing and communications systems found at home and in the workplace is a complex task that currently requires the attention of the user. Researchers have begun to examine computers that would autonomously change their functionality based on observations of who or what was around them. By determining their context, using input from sensor systems distributed throughout the environment, computing devices could personalize themselves to their current user, adapt their behaviour according to their location, or react to their surroundings. The authors present a novel sensor system, suitable for large-scale deployment in indoor environments, which allows the locations of people and equipment to be accurately determined. We also describe some of the context-aware applications that might make use of this fine-grained location information.

Bacterial speck (Pseudomonas syringae pv. tomato) is considered one of the major diseases of tomato crop worldwide and alternative methods to control it are desirable. The objective of this study was to evaluate the effect of essential oils (EOs) on P. syringae pv. tomato strain ufv-1 growth, in controlling bacterial speck in tomato plants, as well as to find the best application time of the EOs. The EOs used in this study were thyme (TH), eucalyptus (EU), tea tree (TT), clove (CL), cinnamon (CN), citronella (CI), and lemon grass (LE). An in vitro test using EOs were conducted to verify the ufv-1 inhibition, and two tests were carried out in a greenhouse to evaluate the effect of EOs before and after inoculation with Pst. Inhibition zones were observed for EU, CI, CL, and CN at a concentration of 1%. Plants pre-treated with EOs showed lower disease severity than that in plants post-treated with EOs (P<0.05), whereas higher efficacy was observed using acibenzolar-S-methyl and CI (91 and 83%, respectively). Regarding post-treatment, TT, TH, CI, EU, LE, and commercial fungicide, resulted in reducing disease severity by 8 to 40% compared to control (water). Results from this study showed the potential use of EOs in controlling bacterial speck in tomato and suggest the induced resistance as the major mode of action.


A study is described of the factors affecting measurements of phytoplankton photosynthesis by the much used field method, based upon changes of oxygen concentration in clear and darkened bottles as determined by the Winkler method. Unialgal cultures of a marine plankton diatom, Chaetoceras affinis, were used with short exposures of 1–3 hours in both laboratory and sea. Indications of a limitation of photosynthetic rate by inadequate CO2 supply were only found for culture media with pH raised by prolonged photosynthesis. Otherwise photosynthetic rates were unaltered by the bicarbonate concentration over a wide range, including that of unenriched sea-water, or by cell sedimentation in unshaken cultures. A comparison of the Winkler and manometric methods of measuring oxygen production gave very similar results. High rates of photosynthesis were well maintained over the main period of each exposure, despite the development of oxygen supersaturation. Lower rates were however always found during an initial induction phase.

Photosynthetic characteristics deduced from exposures in laboratory and sea, carried out almost simultaneously and with the same algal material, were in general agreement. Data from the experiments as a whole indicated the development of unusually high photosynthetic capacities at light saturation, assessed per unit content of chlorophyll a. The onset of light saturation, and the development of photo-inhibition, occurred at intensities similar to those recorded for many other plankton algae. Some ecological implications of the findings are discussed.


Robot storytelling has the potential for its practical use in various domains such as entertainment, education, and rehabilitation. However, relying on human-recorded voices for natural storytelling is costly, and automation with text-to-speech systems is not readily applicable due to the difficulty of reflecting the full nature of stories in TTS systems. In this paper, we address the problem of automating robot storytelling with a particular focus on two issues: speaker identification and speaker-TTS voice mapping. We first conduct text analysis with rich linguistic clues to identify speakers from a given textual story. We then consider the task of speaker-TTS voice mapping as the graph coloring problem and propose effective algorithms for assigning voices to speakers given a limited number of TTS voices. Finally, we perform a user experiment on validating the usefulness of our method. The results demonstrate that our system significantly outperforms baseline systems and is also more acceptable to users.

The government's call for GPs in England to offer all patients smartphone video consultations have been met with scepticism from doctors' leaders and health experts.

In an interview with the Telegraph newspaper published on 12 September, the health and social care secretary, Matt Hancock, said that he wanted to see a system in which all patients could use their smartphone, tablet, or computer to have Skype-like video consultations with their GP.1

Hancock has admitted that he uses the GP at Hand app provided by Babylon Healthcare. The service, which is offered by the NHS in some parts of London, enables patients to have video consultations with a doctor or to arrange a face-to-face …


This study compared obesity prevalence in Mississippi across selected geographic and socio-economic factors.  A unique aspect of this study was the examination of obesity from the perspective of its possible relationship to depression in rural and urban areas.  Policy recommendations included promoting culturally- and geographically-sensitive strategies to address obesity in Mississippi.


Anorexia nervosa (AN) is a childhood psychiatric disorder that is characterized by patientinduced maintained weight loss that leads to progressive malnutrition and specific pathophysiological signs (e.g., disturbance of body image and fear of obesity). The prevalence of different eating disorders in a recent study of a Spanish female adolescent population showed an incidence of 0.1% for AN, 0.7% for bulimia and 2.8% for nonspecified eating disorders, resulting in a total sum of 3.7% of the population suffering from some type of eating disorder . To date, no specific marker indicating susceptibility to AN has been identified. Studies in this field have been focused on the analysis of polymorphisms in genes related to weight control and the serotonergic and dopaminergic systems. The serotonergic system has been implicated in the development of eating disorders. Serotonin (5hydroxytryptamine [5-HT]) is involved in a broad range of biological, physiological and behavioural functions. Studies of polymorphisms within different 5-HT receptor genes have described an association between the -1438 Α-allele of the -1438 G/A polymorphism within the promoter region of the 5-HT2A receptor gene and AN. The aminooxidase A and norepinephrine genes have also been implicated in AN, as well as an association between brain-derived neurotrophic factor (BDNF) and restricting AN and minimum body mass.


Cuckoo search (CS) algorithm is a novel heuristic algorithm, which can effectively solve the optimization problem by simulating the brood parasitism of some cuckoo species and combining with Lévy flight mechanism. However, it has also been shown to have certain weaknesses, especially falling into local optimums. Therefore, a novel CS algorithm with feedback control and local search mechanism (FLCS) is proposed in this paper. In the FLCS, feedback control is introduced to enhance the efficiency of search process, and local search mechanism is guided by the global optimal solution for improving the poor local search ability of CS method. To verify the performance of our approach, 21 test functions of different types are first employed. Then, the FLCS has been performed on the IEEE 30-bus power flow test case for optimal power flow (OPF) problem with valve point effect. The results indicate that the proposed FLCS method clearly has better performance than CS in the solution accuracy and convergence speed. In addition, the comparison results show that FLCS performs better than other evolutionary methods from literature for different functions.

Interest in the analysis of trust in social communications is due to the fact that modern society is subject to a number of global challenges in economics and politics. Young people, as the most susceptible and labile group of the population, may experience the negative impact of these challenges, coupled with a crisis of values and social guidelines. The purpose of the research is to analyze the perceptions of trust among bachelor students from Moscow universities in the context of social communications. Empirical data are presented by the results of a survey of full-time students living in Moscow and the Moscow Region (n = 441, 2021). The theoretical and methodological basis of the study is formed by the theories of trust of Russian and foreign researchers (F. Fukuyama, Yu. Lo, P.M. Doni, V.Yu. Stolyar, P.M. Kozyreva, S.V. Ryzhova, et al.). The scientific novelty of the study is the identified patterns of the phenomenon of trust in the youth environment. The results of the study show the ambiguity of the interpretation of trust by students. In building trusting relationships, honesty, openness and sincerity are most significant for students. Most consider it impossible to have relationships without trust with relatives and friends. In intercultural communications, it is easier for students to trust post-Soviet citizens. For barriers of trust, the most significant was the socio-cultural barrier (difference in mentality, norms, values, the presence of stereotypes, etc.), as well as the language barrier. The conclusions and recommendations presented in the article can be used in further research on student trust, as well as for making managerial decisions to strengthen the value of trust in education.


Fig. 1. To our knowledge, this is the first investigation focusing on capillary serum sampling for microarray-based IgE analysis. Our data suggest that the detection of specific IgE antibodies against multiple recombinant allergen components is feasible and reliable utilizing only minute volumes of patient serum. Allowing for capillary blood sampling, a mode of blood withdrawal particularly suitable for the pediatric age group, it could help avoid peripheral venipuncture which is known to cause procedural distress and not rarely requires local anesthesia in infants and children (5). Therefore, our results strengthen the view of allergen microarrays as promising tools for future low-invasive IgE testing. However, as has been pointed out before (6), further clinical trials with larger numbers of patients are required in order to assess all relevant microarray performance parameters in comparison to established methods of in vitro IgE detection.

Ionic Polymer Transducers (IPTs) can act as both actuators and sensors. As actuators, the energy density values are much better than PZT or PVDF materials. As sensors, IPTs are extraordinarily sensitive and have the potential to be used in any mode of deformation. However, application of IPT sensors is limited because of a lack of understanding of their fundamental physics. In this work, the main focus will be to explore and develop a better understanding of how IPTs function with respect to shear deformation. In turn, the results developed here will improve upon the state of understanding of IPT sensors in general and potentially expand meaningful application opportunities.
Because IPT active response is a multiscale phenomenon, this study adopts a multiscale modeling framework. Of interest are the interplay among the polymeric backbone of the ionic polymer, the diluent present in the hydrophilic regions of the polymer and the interspersed electrode particulate.
To begin, this work improves upon a past multiscale modeling framework for the polymer backbone based upon Rotational Isomeric State Theory such that the effects of material anisotropy may be considered. This is potentially significant in light of the polymer manufacturing process. These modeling results are then incorporated into a model of the diluent movement within the ionic transport regions of the IPT. The electrical current predictions are based upon streaming potential theories. Finally, this model incorporates viscoelastic behavior in order to develop a better understanding of the coupling of these two systems (the polymer and the diluent) and how this coupling influence affects the expected current output over time.


The influences of edge constraint upon the behaviour of single panel ruled surface hyperbolic paraboloids with straight generator boundaries are studied. With apex and base corners clamped in position and against rotation, each of the degenerate clamped, simple and free edge conditions are considered and shown to represent the extreme behaviour of various physical-numerical analogues of the shelledge beam interaction. The significance on over-all shell behaviour of a number of second order shell edge beam Interaction terms are then assessed. Finally consideration is given to an estimation of the significance of stress resultants in the over-all load carrying capacity of the shell.


Linear Elastic Fracture Mechanics (LEFM) provides a quantitative description of the crack motion that agrees well with observations in brittle materials as long as the crack growth is sufficiently slow. However, several issues remain unsolved: (i) experimental observations reveal that at high velocity, the crack speed is systematically smaller than the one predicted by LEFM [1] and (ii) above a given velocity, a dynamically growing crack creates a structure of its own as evidenced from roughening of fracture surfaces at high speed [2]. The aim of this work is to present a statistical study and a deterministic reconstruction of the morphology of the fracture surfaces in Plexiglas obtained under dynamic conditions.

Ever since reproductive technology became widely available to treat fertility problems, some physicians have tried to limit access to this technology for various reasons, including the age, marital status, and sexual orientation of patients.1 In a landmark ruling, the California Supreme Court recently held that clinic physicians may not deny lesbians access to fertility treatment on the grounds that the procedure violated the physicians' religious beliefs.2 The court found that neither the federal nor state constitutional rights to free exercise of religion exempted the doctors from following antidiscrimination provisions in California's Unruh Civil Rights Act (Unruh Act).3 In reaching this result, the court held that the federal free exercise right did not justify noncompliance with a neutral and generally applicable law.4 It went on to find that even if the state constitution granted stronger protection, the physicians' interests in religious freedom still did not overcome the state's compelling interest in ensuring equal access to reproductive treatment.5 In so ruling, the court resolved the dispute at hand, but avoided answering the fundamental legal question of what level of


Objective:To establish an HPLC method for simultaneous quantification of the four bioactive components(chlorogenic acid,caffeic acid,1,5-di-O-caffeoylquinic acid and scutellarin)in Herba Erigerontis.Methods:The analysis was performed on Zorbax C18 column(4.6 mm×150 mm,5 μm)with a gradient mobile phase of acetonitrile(A)-0.05% phosphoric acid solution(B)(0-9 min,10%A;9-10 min,10%A→13%A;10-40 min,13%A)at a flow rate of 1.0 mL·min-1,the column was maintained at 30 ℃,and the detection wavelength was set at 325 nm.Results:The linear ranges are 3.93-62.9 μg·mL-1(r=0.9999)for chlorogenic acid,0.106-1.70 μg·mL-1(r=0.9997)for caffeic acid,0.124-1.98 μg·mL-1(r=0.9995)for 1,5-di-O-caffeoylquinic acid and 28.78-460.4 μg·mL-1(r=0.9999)for scutellarin.The average recoveries(n=6)of the four components were 95.74% with RSD=1.7%,103.3% with RSD=2.6%,100.0% with RSD=4.0%,and 101.8% with RSD=3.4%,respectively.Conclusion:The validated method has advantage of simplicity and precision,it can be used to assess the quality of Herba Erigerontis.


The present‐day deformation of the Tianshan Mountain range is largely resulting from the collision between India and the Eurasian plate, but the mechanism causing its uplift remains controversial. In this study, we present the contemporary tectonic and geodynamic processes resulting in the growth of the Tianshan Mountain range as revealed by integrating Global Positioning System (GPS) and Gravity Recovery and Climate Experiment (GRACE) measurements during 2010–2016. The average ground uplift rate is 0.72 ± 0.12 mm/year, of which 0.39 mm/year is attributed to elastic effects of glacier melting. The residual average tectonic uplift rate of 0.33 ± 0.12 mm/year closely matches the crustal thickening rate (0.33 ± 0.03 mm/year), indicating that horizontal compression plays an essential role in Tianshan orogeny. We also find the Lake Issyk‐Kul region is converging and subsiding, which can be explained by a regional crust folding model. The interaction of adjacent rigid blocks in the Tianshan and surrounding areas is also manifested by the crustal shortening derived from GPS horizontal velocities. This study provides new geodetic results and a new model in current orogenic movement in the Tianshan Mountain range and highlights its complexity.

The response of bean fruiting to HF fumigation was investigated in a series of experiments. The plants were exposed to various concentrations of HF, either for 7 to 14 days at different times relative to flowering or continuously from seeding to harvest. To accentuate the response to HF, the plants were grown with with low calcium (40 ppM) nutrient solution in most studies. Hydrogen fluoride treatments averaging up to 8.0 ..mu..g F/m/sup 3/ for 9 days and 7.8 ..mu..g F/m/sup 3/ for 14 days, applied before, during, or after flowering, had no apparent effects on fruiting of any of four varieties of beans.

All medical care should seek to achieve one or more of three goals: to prevent future suffering, to relieve suffering, or to prolong life. Detecting low-grade indolent cancer may not further any of these goals.


Abstract Background Antibiotic stewardship initiatives can leverage metrics that make peer-peer comparisons. A commonly used metric measures how frequently a clinician prescribes antibiotics for acute respiratory infections (ARIs), as defined by diagnostic codes. However, it is unclear if clinicians differ in their use of ARI diagnostic codes. In this study, we evaluated differences in how frequently clinicians code for ARIs and factors that are associated with the use of ARI diagnostic codes in Emergency Department (ED) and Urgent Care (UC) visits across an integrated healthcare system. Methods We analyzed a retrospective cohort of all ED and UC patient-visits across 129 Veterans Affairs medical centers during 2016-2018. ARI visits were identified using ICD-10 codes for acute bronchitis, influenza, pharyngitis, sinusitis, and upper respiratory tract infections for clinicians with 100 or more visits. A generalized linear mixed model with a link logit function that accounted for clustering at the clinician and facility-level was used to calculate median odds ratios (OR) and to identify factors associated with increased likelihood of entering an ARI code. Results There were 6,016,499 patient-visits, and 519,389 (8.6%) were coded as an ARI (Table 1). The mean rate of ARI diagnoses across all visits was 8.9% (SD 2.5%) at the facility-level and 7.4% (SD 4.5%) at the clinician-level (Table 2). The median OR was 2.19 (95% CI 2.18, 2.22), suggesting there was between-clinician variation in coding for ARI diagnoses. Visits were significantly more likely to be coded as ARIs if seen by an advanced practice provider (OR=2.36, 95% CI 2.19, 2.54), if a fever was recorded (OR=4.20, 95% CI 4.18, 4.29), and if the visit occurred between December-March (OR=1.97, 95% CI 1.96, 1.98). Approximately 2/5th of the variability (41.4%) in assigning an ARI diagnostic code was explained by differences across individual clinicians. Conclusion There was substantial variability in how frequently ED and UC clinicians coded a visit as an ARI, and a large proportion of the variability was explained by differences across clinicians. Unmeasured factors could include different approaches to using diagnostic codes. ARI metrics based on diagnostic codes may need to account for differences in clinicians' coding behavior.

In this study, opinions of social studies teachers about in-service trainings have been investigated using quantitative methods.105 social studies teachers working in public schools in Istanbul Kucukcekmece affiliated to the Ministry of National Education participated in this research. In the analysis of teachers' responses for 20 different activities, descriptive analysis was made with the SPSS statistical program and in this way, the percentage and frequency distributions of the data were obtained. As a result, it was determined that the participation of social studies teachers in the training, seminar and course activities named in the survey is low. In addition, it has been observed that social studies teachers have very low level of participation in other courses, education and seminars apart from those 20 activities named in the survey. According to the results of the analysis, it was observed that the teachers did not consider themselves sufficient regarding the training, seminar and course activities which they did not attend. According to another analysis' result, it was observed that social studies teachers did not consider the activities in the survey unnecessary for the social studies field and stated that they could participate in these activities in the future. In the research, the activities that the social studies teachers attended the most and the activities they attended the least were determined. In addition, activities in which social studies teachers' perceptions of competence were highest and lowest were determined. In addition, among the activities in the survey, the activities that teachers deemed most unnecessary and necessary for the social studies field were determined.

Our contribution focuses on precariousness as experienced in the research sector. The article firstly offers a theoretical framework for precariousness, conceptualized as an interweaving and a co-construction of working and existential conditions. We then describe the most salient regulatory aspects of the academic labour market in Italy, in order to contextualize our research findings within the Italian University system. The research was conducted between 2014 and 2015 in two departments situated in the northeast of the country, the first belonging to the STEM field and the second to SSH disciplines. Thirty-two interviews were conducted with postdoctoral research fellows who, at the time of the research, worked, or had recently ended their collaboration, within the two departments under study. The section dedicated to the presentation of findings is focused firstly on the issue of invisibility of precarious researchers, declined both in terms of gender differences, and of the different level of recognition of postdocs' working activities in the STEM compared to the SSH department. Secondly, attention is paid to the status of postdocs, on their complicated positioning between formal and informal work and on their substantial exclusion from social protection. In the concluding section, our contribution put in dialogue the individual experiences analysed within the case study with recent movements developed at the national level by precarious researchers, which focus precisely on a collective claim about the issues of recognition of work and access to welfare.


For British mycologists the year 1978 will be memorable for the publication of the first comprehensive fungus flora of a large and well-wooded hebridean island, Henderson & Watling's Fungi of Mull. After four year's collecting, over every month from March to October, they were able to record only 1787 species, including imperfecti, and it must be accepted that because of the ephemeral or inconspicuous character of their fructifications, it is much more difficult to obtain an adequate record of a fungus flora than of any other group of plants. Only eleven miles south of the Ross of Mull lies the small island Colonsay, eight miles long, relatively low-lying and, unlike Mull, composed of Torridonian rocks. Its average rainfall of 1500 mm, though much less than that of the greater part of Mull, is similar to that of the Ross, Ulva, Mornish and Mishnish and greater than that of Iona, though Colonsay, like the latter, commonly suffers a water-shortage in late summer. In spite of its small area it houses extensive old established plantations of angiosperms and conifers and, of greater interest, rather large apparently native woods of Betula and Quercus fringing its sheltered northeast coast. The fungus flora may thus be expected largely to duplicate that of its larger neighbour and it was a little surprising to find that 76 of the 319 fungi collected during two short visits in August 1978 and September 1976 are not recorded in the Mull flora. In view of the close proximity of the two islands, with their similar climates and environments, it is unlikely the great majority of these do not in fact occur also on the much larger island, and the occurrence of so high a proportion of additional species in so small a sample is an indication of how much more intensive collecting will be required before there can be an adequate record of the true fungus flora of Mull. Oronsay is a small island separated from Colonsay by a narrow sound dry at half tide. It is virtually treeless and contributed few records to the list. As usual I am greatly indebted to Dr D. A. Reid for help in naming difficult Basidiomycetes and to the staff of the Commonwealth Mycological Institute for assistance with Fungi imperfecti. An * preceding the name of a species indicates that it is not listed in the Mull Flora. All localities are in Colonsay unless Oronsay is specified.


Background: The 42 amino acid long amyloid beta peptide (Aβ42) plays a pivotal role in Alzheimer disease. Results: A novel assay was developed and enabled us to describe the process of Αβ42 production and modulation. Conclusion: Aβ42 is generated through different pathways, which are differently affected by disease causing mutations and anti-amyloidogenic drugs. Significance: The data provide key information for therapeutic development in Alzheimer disease. Processing of the amyloid precursor protein (APP) by γ-secretase results in generation of Aβ peptides of different lengths ranging from 51 to 30 residues. Accumulation of Aβ and in particular Aβ42 is enhanced by familial Alzheimer disease (FAD) causing mutations in APP and is believed to play a pivotal role. The molecular mechanism underlying normal Aβ production, the impact of FAD mutations on this process and how anti-amyloidogenic γ-secretase modulators (GSMs) cause a selective decrease in Aβ40 and Aβ42 and an increase in shorter Aβ peptides, however, is poorly understood. By using a combined immuno- and LC-MS-based assay we identify several major intermediates, i.e. 3- and 4-peptides that line up head to head across the entire APP transmembrane sequence from Aβ51 to Aβ31/Aβ30 and from Aβ49 to Aβ30/31. FAD APP mutations displayed a relative increase in 3- and 4-peptides from Aβ48 to Aβ38 compared with Aβ49 to Aβ37. These findings correlate with an increase in the Aβ42/40 ratio. GSMs caused a decrease in Aβ40 and Aβ42 and an increase in Aβ37 and Aβ38 paralleled by an increase of the intermediates Aβ40–38 and Aβ42–39. Collectively, these data provide a thorough characterization of all intermediate steps in Aβ production in native cell membranes and provide key mechanistic insights to genetic and pharmacological modulation of Aβ generation.

Consider the poor, beleaguered Programming Languages course! Most computer science instructors would recognize this as a not-unusual computer science undergraduate course, usually at the upper division and often a junior-level course. ACM's Computing Curriculum 2001 (CC2001, http://www.sigcse.org/cc2001/) largely left it out. CC2001 included four example implementations of the intermediate level of the Computer Science curriculum in its Chapter 8. Only one of these four, the intensive systems-based example approach, makes mention of something approaching this course, and that example course's title, "CS240s - Programming Languages Translation", might be taken by some to not be the same thing at all. And, CS240s's link is not even operational.


When a new vulnerability is discovered, a Common Vulnerability and Exposure (CVE) number is publicly assigned to it. The vulnerability is then analyzed by the US National Institute of Standards and Technology (NIST) whose Common Vulnerability Scoring System (CVSS) evaluates a severity score that ranges from 0 to 10 for the vulnerability. On average, NIST takes 132.7 days for this — but early knowledge of the CVSS score is critical for enterprise security managers to take defensive actions (e.g. patch prioritization). We present VASE (Vulnerability Analysis and Scoring Engine) that uses Twitter discussions about CVEs to predict CVSS scores before the official assessments from NIST. In order to leverage the intrinsic correlations between different vulnerabilities, VASE adopts a graph convolutional network (GCN) model in which nodes correspond to CVEs. In addition, we propose a novel attention-based input embedding method to extract useful latent features for each CVE node. We show on real-world data that VASE obtains a mean absolute error (MAE) of 1.255 for predicting the CVSS score using only three days of Twitter discussion data after the date a vulnerability is first mentioned on Twitter. VASE can provide predictions for the CVSS scores for 37.85% of the CVEs at least one week earlier than the official assessments by NIST.


[Purpose] The purpose of this study was to conduct a passive intervention program and an active intervention program for healthy subjects for six weeks, and analyze and compare their effects on the neck's muscular strength and endurance and the joint range of motion (ROM). [Subjects] This study selected 28 undergraduates as subjects and allocated them randomly and equally to either the passive intervention program group (PIPG) or the active intervention program group (AIPG). [Methods] The cranio-cervical flexion test (CCFT) was modified to measure the deep neck flexor (DNF)'s strength and endurance, and the cervical range of motion (CROM) was measured to compare and analyze flexion, extension, right lateral flexion (RLF), left lateral flexion (LLF), right rotation (RR), and left rotation (LR) of the neck. [Results] Both the PIPG and the AIPG showed significant improvements in the measured items post-intervention. In a comparison of the two groups, strength, endurance, flexion, and extension in the AIPG were significantly better than their respective values in PIPG. [Conclusion] In treating deep neck flexors, an active intervention program is more effective than a passive intervention program at improving muscular strength, muscular endurance, and joint ROM.


Cacao (Theobroma cacao) and copoazú (T. grandiflorum) agroecosystems represent a common source of income or many small-scale farmers in the Colombian Amazon basin. Most of these systems are set in low disturbance environments; they are considered biodiversity-friendly ecosystems inhabited by several groups of insects. In this study, we carried out a preliminary taxonomic inventory of the microhymenopteran parasitoids present in these agroforestry systems. Twenty-six localities of the Amazonian basin of Colombia were sampled using several insect collecting methods (Malaise trap, sweep net, pitfall, and rearing boxes). Collected specimens were curated and cataloged, establishing the first taxonomic voucher collection of parasitoids from the Colombian Amazon basin. We identified 767 specimens representing 64 species, 274 morphospecies, 143 genera and 20 families, 34 genera and 16 species of these being recorded for the first time in the country. The genus Gbelcia is reported for the first time from the Neotropical region. A new parasitoid-host relationship was found for Horismenus cupreus (Eulophidae) attacking larvae of Phyllocnistis sp. (Lepidoptera, Gracillariidae), which feeds on Annona montana (Annonaceae) leaves.


There is a key problem in the fabricating sub-micron mask with lithography, which is how to improve accuracy of the mask by reducing the proximity effects. Backscattering electrons is the main factor of causing proximity effects. In this paper, we use random probability number to determine whether there is an elastic scattering happening between resist and Cr plate in the EB lithographing process. The distribution of the scattering electrons' energy deposition in PMIMA resist is simulated. The graphs of the forward scattering energy deposition and backscattering energy deposition have been given. This is useful to amend the proximity effects.


The effects of innovational outliers and additive outliers in cointegrated vector autoregressive models are examined and it is analyzed how outliers can be modelled with dummy variables. A Monte Carlo simulation illustrates that additive outliers are more distortionary than innovational outliers, and misspecified dummies may distort inference on the cointegration rank in finite samples. These findings question the common practice in applied cointegration analyses of including unrestricted dummy variables to account for large residuals. Instead it is suggested to focus on additive outliers, or to test the adequacy of a particular specification of dummies prior to testing for the cointegration rank. The points are illustrated on a UK money demand data set. Copyright Royal Economic Socciety 2004


ESSENTIAL hypertension is a very common condition, and expanding intracranial lesions are common enough so that coexistence of the two may be anticipated. The symptoms (impairment of vision, headache, nausea, vomiting, convulsions, stupor, unconsciousness and coma), physical findings (papilledema and localizing signs) and spinal-fluid alterations (increased pressure and elevated protein) may occur both in severe hypertension and in brain tumor. Increased intracranial pressure associated with a slowly expanding intracranial lesion is not accompanied by a significant increase in the blood pressure. The presence of an acutely expanding intracranial lesion (from trauma or hemorrhage), which may cause an elevation of the . . .


As we move toward exascale platforms, silent data corruptions (SDC) are likely to occur more frequently. Such errors can lead to incorrect results. Attempts have been made to use generic algorithms to detect such errors. Such detectors have demonstrated high precision and recall for detecting errors, but only if they run immediately after an error has been injected. In this paper, we propose a neural network detector that can detect SDCs even multiple iterations after they were injected. We have evaluated our detector with 6 FLASH applications and 2 Mantevo mini-apps. Experiments show that our detector can detect more than 89% of SDCs with a false positive rate of less than 2%.

Abstract : Tactical simulation models used by the Department of Defense to assess the capabilities of combat systems and tactics are highly complex. It is often difficult to determine the relationship of individual factors to the performance of the modeled process. A technique called metamodeling has the ability to address this problem. This research developed the capability to build dynamic metamodels of tactical engagement simulations.

The paper aims to present the early stages in the implementation of a Geographic Information System in the field of archaeology and its advantages. This field uses the spatial information in the required activities, whether in research or management. The chosen area of study is located in the West part of Gala i City. We used as support data the orthophotoplans of that area, produced by National Agency for Cadastre and Land Registration, a topographical map produced by D.T.M, sets of photographs of archaeological sites in the area, taken from the helicopter and a LiDAR dataset for the archaeological site from "B rbo i".I wanted to highlight the placement of these objectives in the area of study and to present the potential that LiDAR technology has in archaeology. For this I drew up a situation plan based on the digitised data, I realised a Digital Terrain Model using contours and points of known elevation from the topographic map. I generated a Digital Terrain Model based on LiDAR data, for archaeological site from "B rbo i" and I showed a few of the analysis possibilities on the basis of this model.


The adsorption of poloxamer block copolymer surfactants onto hydrophobic surfaces is of interest as a means of stabilizing suspensions and creams, and as a research tool for organ‐specific delivery of colloidal particles. In this study, adsorption of poloxamers to a model hydrophobic drug (atovaquone) has been studied at a range of temperatures. It was noted that the adsorption first falls, then rises and falls again as the temperature is increased. As adsorption is generally exothermic, such behaviour is unusual. The explanation for these observations is based on the existence of a phase transition in aqueous solutions of these surfactants at specific temperatures which may be a critical micelle temperature. The observations reported here are of significance for conventional and targeted drug‐delivery systems which include poloxamers. 1995 Royal Pharmaceutical Society of Great Britain


This paper aims at understanding the expectations of a group of parents, about possibilities and problems Information and Communication Technologies (ICT) present for their children. The article consists in a qualitative study, through the in-depth interview technique. Participants were twenty fathers and mothers with children from 9 to 18 years of age, studying at private and state schools of Teruel (Spain). All of them are concerned about the subject, because have been selected after attending several discussions and classes about technologies and students organized by cultural and educational associations. Computer Assisted Qualitative Data Analysis Software (CAQDAS) was used, by means of Atlas.ti7 program. The findings show a similar amount of advantages lightly higher than the number of downsides. Parents appreciate ICT mainly as a way of communication and cooperation, in addition to entertainment. Regarding daily downsides, the fundamental ones are related to the deterioration of social and family environment, different levels of addiction –in a broad sense- and the uncertainty they notice to face with possible damages, because of the difficulty to foresee and control. In conclusion, due to the fact that nowadays ICT make impossible a strict monitoring of their potential risks, parents must improve their teaching and training skills to prevent unwanted effects, and empower their children with autonomy and self-control. The best way for it could be precisely the strong communicative components associated with parent-children relationship. The benefit for having interviewed only involved parents is at the same time its major limitation; even though further research will be necessary, these results shed light on one of the most interesting issues related to ICT: the key role of family.


Radiolabeled eluates of human anti-D were used to measure the capacity of leukocytes to bind the D antibody in cell suspensions prepared from 16 normal and 3 leukemic bloods from Rh(D) donors. The contamination of the leukocyte suspensions by D positive red cells was measured and the contribution of D antigen sites by these cells was estimated. After correction was made for the D antibody bound by the contaminant red cells, no specific binding of D antibody by Rh(D) leukocytes could be detected. Three pairs of Rh(D) and rh(d) leukocyte dilution curves of I131-labeled anti-D uptake were compared with the uptake by D positive and D negative red cell dilutions. No significant differences among the D negative erythrocyte, the rh(d) leukocyte and the Rh(D) leukocyte curves were obtained. The results were collated with previous serologic evidence concerning the presence of ABO and Rh antigens on human leukocytes.

The droplet size influences application effect of spraying technique and therefore GM(1,1) model for predicting droplet size is established using grey theory.The experiments show that the method has high prediction accuracy and can provide guidence for the choice of spraying system parameters within a certain droplet size scope.


In recent years, based on peptide models of HIV‐1 RNA binding, NMR structures of Tat‐responsive element–ligand complexes and aminoglycoside–RNA interactions, and HIV‐1 Tat structure, we have designed and synthesized aminoglycoside–arginine conjugates (AACs) and aminoglycoside poly‐arginine conjugates (APACs), to serve as Tat mimetics. These novel molecules inhibit HIV‐1 infectivity with 50% effective concentration values in the low micromolar range, the most potent compounds being the hexa‐arginine–neomycin B and nona‐d‐arginine–neomycin conjugates. Importantly, these compounds, in addition to acting as Tat antagonists, inhibit HIV‐1 infectivity by blocking several steps in HIV‐1 cell entry. The AACs and APACs inhibit HIV‐1 cell entry by interacting with gp120 at the CD4‐binding site, by interacting with CXCR4 at the binding site of the CXCR4 mAb 12G5, and apparently by interacting with transient structures of the ectodomain of gp41. In the current review, we discuss the mechanisms of anti‐HIV‐1 activities of these AACs, APACs and other aminoglycoside derivatives in detail. Targeting several key processes in the viral life cycle by the same compound not only may increase its antiviral efficacy, but more importantly, may reduce the capacity of the virus to develop resistance to the compound. AACs and APACs may thus serve as leading compounds for the development of multitargeting novel HIV‐1 inhibitors.


Kidney Disease and kidney failure is the one of the complicated and challenging health issues regarding human health. Without having any symptoms few diseases are detected in later stages which results in dialysis. Advanced excavating technologies can always give various possibilities to deal with the situation by determining important realations and associations in drilling down health related data.   The prediction accuracy of classification algorithms depends upon appropriate Feature Selection (FS) algorithms decrease the number of features from collection of data. FS is the procedure of choosing the most relevant features, removing irrelevant features. To identify the Chronic Kidney Disease (CKD), Hybrid Wrapper and Filter based FS (HWFFS) algorithm is proposed to reduce the dimension of CKD dataset.   Filter based FS algorithm is performed based on the three major functions: Information Gain (IG), Correlation Based Feature Selection (CFS) and Consistency Based Subset Evaluation (CS) algorithms respectively. Wrapper based FS algorithm is performed based on the Enhanced Immune Clonal Selection (EICS) algorithm to choose most important features from the CKD dataset.  The results from these FS algorithms are combined with new HWFFS algorithm using classification threshold value.  Finally Support Vector Machine (SVM) based prediction algorithm be proposed in order to predict CKD and being evaluated on the MATLAB platform. The results demonstrated with the purpose of the SVM classifier by using HWFFS algorithm provides higher prediction rate in the diagnosis of CKD when compared to other classification algorithms.


The construction industry lags behind other sectors in terms of productivity performance, with many megaprojects experiencing cost overruns. While there are various reasons for this, the most significant one is the lack of efficiency. Adopting the off-site construction (OSC) methodology can improve productivity by enhancing project efficiency mainly in terms of time, cost and quality. Although OSC, off-site manufacturing (OSM), Industrialized Building System (IBS), prefabrication, modular, or other similar terms are not novel concepts, it is essential to shift any aspect of construction project activity from traditional onsite methods to a controlled, factory-based and manufacturing concept of production. Industrialization and digital fabrication have gained significant prominence in recent years, as they are perceived as a viable solution to the issues faced by the construction sector. As OSC is gradually gaining interest in building projects, it is crucial to identify and validate the key decision support factors (KDSFs) for selecting an appropriate OSC method from the early design stage. The purpose of this study is to identify, verify, and evaluate the KDSF for selecting OSC in Canada. This study utilized a mixed-methods design, comprising a systematic literature review (SLR) and pilot expert reviews through semi-structured interviews and surveys, to accomplish the research objectives and ensure the validity and reliability of the findings. Twelve interviews were conducted to validate and analyze the KDSFs, which were then prioritized using the mean score (MS) analysis and weighting function. Based on the research methodology, 32 KDSFs were validated and grouped into 7 'dimensions'. Further analysis concluded that the most important 'dimension' in selecting OSC for a building project in Canada is project time which consists of the design period, production time, mobilization and transfer time, as well as the assembly, and construction periods.


Incarcerated people face significant information poverty, both because of limited access to information resources and because incarceration itself produces information needs that cannot be easily met. Through a content analysis of reference questions directed to the New York Public Library's Correctional Services Program, this study articulates the particular information needs of these users. Information needs cluster around self-help and re-entry information, along with general reference queries that typically go unanswered due to the lack of access to the Internet and robust general libraries in correctional facilities. Understanding these needs offers insight for librarians and libraries seeking to better serve incarcerated populations.


Three instruments——TAS-20,TSCS and CSQ are used to survey 284 female criminals,75 high self-conception and 76 low self-conception women were chosen from them,their data of self-conception,alexithymia and coping style were analysed.The results show that with the self-conception promotion,the female criminals' alexithymia drops,and their positive coping styles rise,negative coping styles drop.Self-criticism has positive relation with identity disorder.


The effect of deflector curvature on hydrodynamic performances of a double-slotted cambered otter-board was investigated using engineering models in a wind tunnel. Four different curvature (0.06,0.09, 0.12 and 0.15) were evaluated at a wind speed of 28 m/s. Parameters measured included: drag coefficient C x , lift coefficient C y , pitch moment coefficient C m , center of pressure coefficient C p , over a range of angle of attack (0° to 70°). These coefficients were used in analyzing the differences in the performance among the four otter-board models. Results showed that the maximum lift coefficient C y of the otter-board model with the curvature (0.06) of two deflectors was highest (2.020 at °=55°). The maximum C y /C x of the otter-board with the curvature (0.12) of two deflectors was highest (3.655 at °=22.5°). A comparative analysis of C m and C p showed that the stability of otter-board model with the curvature (0.12) of two deflectors is better in pitch, and the stability of otter-board model with the curvature (0.06) of two deflectors is better in roll. The findings of this study can offer useful reference data for the structural optimization of otter-boards for trawling.


This study analyzed user behaviors on Epinions and generated the following findings. The frequency of the trusting, writing, and rating behaviors of Epinions users demonstrated a power law distribution. Only a small group of users were active on Epinions then. The majority of users obtained trust from only a small group of users, whereas only a small group of Epinions users were trusted by a sizable group. Therefore, most Epinions users were information receivers, whereas only a small group of users were information providers. The intervals of writing, trusting, and rating behaviors on Epinions followed power law distributions, conforming to the results of previous human dynamics studies. The interval of reciprocation also exhibited a power law distribution. The small proportion of reciprocation among Epinions users reflected a distinction between an online trust-relationship network and a real-world social network. Trusting, writing, and rating behaviors on Epinions exhibited patterns similar to power law declines and their frequency fluctuated in later periods. Finally, this study proposed a model on the basis of diminishing user activity over time. By describing the probability of participating in a behavior on Day t and conducting simulation calculations, this study found that this model fit the power law distribution characteristics of user behavior intervals and could thereby serve as an adequate human dynamics model.


Since the end of the World War II, Europe has been repeatedly afflicted by waves of brain drain, with varying degrees of intensity across time and countries. But these outflows of human capital have rarely turned into some form of brain circulation, nor have they been compensated by adequate inflows of foreign talents. Now, the Digital Revolution and the economic restructuring imposed by a never-ending Eurozone crisis are amplifying the costs of these human capital losses, creating skills shortages that are undermining Europe's ability to compete globally. So far, the European Commission (EC) has taken steps to loosen immigration policies to attract skilled foreigners from across the world. A thorough historical analysis, however, will show that it is high time for European governments to reattract their runaways. Policies aiming at remigration, rather than immigration, will generate greater political and economic efficiency. (1) ********** In a world of blurring national borders and growing demand for sophisticated skills, governments struggle to retain their brightest minds. When institutional deficiencies, technological inertia, or political cronyism prevent people from realizing their full potential, no country--even the most developed--is immune to the outflow of its best talents. In this sense, Europe is a case in point. For more than half a century, bright academics, ambitious entrepreneurs, and visionary scientists have defeated the conservatism of Europe by crossing the Atlantic Ocean in search of vibrant university environments and rewarding professional opportunities. These emigrants are not only Europe's most skilled workers but, according to several metrics, also the most gifted in their respective fields globally, with their "quality"--expressed in terms of educational and professional backgrounds--having significantly increased over time. In short, this is the brain drain of "la creme de la creme." (2) To make matters worse, Europe's outflows of human capital have rarely been compensated by adequate inflows of equally skilled foreign talents from either developed or developing economies. An inward-looking, innovation-averse Europe is not the ideal place for gifted foreigners who are willing to bear the cost of emigration. The number of skilled American workers who decide to move to Europe is much lower than the number of Europeans who are now part of the U.S. workforce. (3) At the same time, the most skilled professionals from the developing world, such as scientists, engineers, and academic researchers, tend to look to the United States as their second home. (4) Now, the Digital Revolution and the economic restructuring imposed by the Eurozone crisis are amplifying the costs of these human capital losses by boosting the demand for those very same skills that are usually possessed by European emigrants. On the one hand, the proliferation of digital startups and the emergence of disruptive technologies, such as advanced robotics or machine intelligence, are radically reshaping the business landscape. On the other hand, the bursting of bubbles in oversized real estate sectors and a general lack of competitiveness in the Eurozone periphery call for a radical economic overhaul. These two sets of transformative forces together create skill mismatches that generate high social costs, such as long-term unemployment for displaced workers in declining sectors who are unlikely to find jobs in emerging fields. Growing skills shortages are already plaguing the European economy. Despite an extremely underutilized labor force, around 27 percent of yearly vacancies in the major European economies go unfilled due to skill mismatches. (5) The Skills Mismatch Index (SMI) for the Eurozone as a whole--an indicator commonly used by the EC and the European Central Bank to gauge skills shortages--is now five times higher than in 2007. (6) Contrary to conventional wisdom, the skills mismatch affects both skilled and unskilled workers, indicating that universities often fail to equip students with adequate and marketable competencies. …

A closed-form high-order analytical solution for the analysis of concrete beams strengthened with externally bonded fiber-reinforced plastic (FRP) strips is presented. The model is based on equilibrium and deformations compatibility requirements in and between all parts of the strengthened beam, i.e., the concrete beam, the FRP strip, and the adhesive layer. The governing equations representing the behavior of the strengthened beam, along with the appropriate boundary and the continuity conditions, are derived and solved with closed-form analytical solutions. Comparison of the closed-form high-order model with other simplified approaches, based on one- and two-parameter elastic foundation concepts, is included. It is shown that the current high-order model can be reduced, by omitting the appropriate terms, to the simplified theories. A numerical example of a typical RC beam strengthened with an externally bonded FRP strip is discussed with emphasis on the shear and peeling stress concentration distributions at the edge of the FRP strip. Stress analysis results concerning the edge stresses determined by the high-order model are compared with those determined by the elastic foundation models and finite elements. Finally, a parametric study that characterizes the main parameters governing the magnitude and intensity of the edge stresses if performed. The paper is concluded with a summary and recommendations for the design of the strengthened beam.

ABSTRACT Apprenticeships are a common pathway for young people transitioning from education to employment, and adolescence to adulthood. Apprenticeships have undergone considerable reform, and since the 1990s labour market priorities in Australia have resulted in weakening of protections offered to workers through the award system and trade unions. At the same time, mental health issues have increased, with young people carrying a disproportionate burden. The aim of this study was to explore challenges that young apprentices in urban Australian settings face in relation to their mental health. Focus groups were conducted with 54 apprentices, who described a pervasive sense of disposability and poor working conditions as the main challenges to their mental health. These conditions included long work hours, low wages, job insecurity, poor quality education, unrealistic expectations, workplace hierarchies and bullying. Amidst social and economic precarity, apprentices resigned themselves to silently endure poor treatment in their work placements. Findings from this study are especially troubling because, as young people, apprentices simultaneously face a series of life transitions that require support and guidance. This paper brings attention to the workplace conditions that may contribute to young apprentices' vulnerability to mental health problems, highlighting possibilities for structural changes led by policy reform.


The current study examines the relationship between two social dimensions of trust (competence and warmth) and occupational frequency reference in several language corpora. Using archival data, Study 1 demonstrates a positive relationship between occupational frequency and ratings of prestige in user-generated content. Using experimental data, Study 2 found that a positive relationship between users' ratings of social warmth and GoogleTrends data. Taken together, these results suggest that the two dimensions of trust might differ in terms how they are used to promote, and the change the perception of, source credibility.


Two concentric corrugated cylinders are separated by a viscous fluid. When the inner cylinder is rotated, unsteady and steady torque and forces may be generated. Assuming low Reynolds numbers and small amplitude corrugations, the Navier–Stokes equations are solved by perturbations to second order. The torque and forces are dependent on the gap width, the amplitude of corrugations, and especially the number of waves of the corrugations.


South African society is attempting to transform from an institutionalised
prejudiced society to one of national unity and democracy. Recent legislation
aims to eradicate discrimination within commercial organisations. The aim of this
research is to examine experiences and perceptions of sexual discrimination
within the legal profession. A triangulatory approach was employed using a
survey-type questionnaire with some open-ended and closed-ended qualitative
questions. 46 attorneys were surveyed and a range of techniques was used to
analyse the qualitative and quantitative information. The most significant results
indicate a greater prevalence of indirect as opposed to direct sexual
discrimination. Reverse discrimination appears to be integral in males'
experiences of sexual discrimination, whereas maternity issues appear to be
prominent in females' experiences.


T

he paper uses Heckman model to examine the statistical importance of over 140 independent variables on the Olympic performance of all countries participating in the Summer Olympic Games from Sydney 2000 to Rio 2016. We find that countries which export more products have a higher likelihood of winning an Olympic medal than their counterparts exporting fewer products, and explain why this is the case. Statistical importance of gross domestic product per capita, labor force, average temperature and three host effects (previous host, current host, future host) is also confirmed while the role of political variables in Olympic success remains inconclusive.
