We extend our previous theory of etale parallel transport to a larger class of slope zero vector bundles on p-adic curves. The new class is stable under pullback by ramified coverings. We also construct p-adic representations of a central extension of the fundamental group for certain bundles of non-zero slope.


North Korea and its nuclear programme has been the main security issue in East Asia. After the US accused Pyongyang of cheating on its obligations under the Nuclear Non-Proliferation Treaty (NPT), and under the 1994 Agreed Framework, North Korea declared its intent to re-activate the Yongbyon nuclear facility. Subsequently it withdrew from the NPT and ordered IAEA inspectors to leave the country. In Japan, debate has focused on how the Self Defense Forces can participate in multinational peacekeeping operations, whilst retaining their constitutional position. Meanwhile, China has continued its defence reform programme, with reductions in the establishment of the People's Liberation Army (PLA). At the same time, the Chinese have launched a new round of defence diplomacy aimed at re-establishing military-to-military exchanges with the US and strengthening defence and security links with neighbouring countries in Central Asia and the Asia-Pacific region. However, the 2003 US Annual Report on the Military Power of the People's Republic of China stated that Chinese short-range ballistic missile production has increased, causing further tension across the Taiwan Straits. Meanwhile, Taiwan has carried out its own military reforms. In Southeast Asia, the terrorist attack in Bali on 12 October 2002 brought the 'war on terror' firmly to the forefront of Indonesia's security concerns. The Islamic militant group Jemaah Islamiah (JI) was widely suspected of carrying out the attack and of having links to al-Qaeda. Cooperation between security forces in the region increased as a result, although traditional security concerns also remain in evidence. Following their support for Operation Enduring Freedom, Australian defence forces played a significant role in military operations in Iraq, a deployment titled Operation Falconer. Also, signalling an increasing role in regional security, Australian forces deployed to Solomon Islands in July 2003.

The nature of GW190425, a presumed binary neutron star (BNS) merger detected by the LIGO/Virgo Scientific Collaboration (LVC) with a total mass of $3.4^{+0.3}_{-0.1}$ M⊙, remains a mystery. With such a large total mass, GW190425 stands at five standard deviations away from the total mass distribution of Galactic BNSs of 2.66 ± 0.12 M⊙. LVC suggested that this system could be a BNS formed from a fast-merging channel rendering its non-detection at radio wavelengths due to selection effects. BNSs with orbital periods less than a few hours – progenitors of LIGO/Virgo mergers – are prime target candidates for the future Laser Interferometer Space Antenna (LISA). If GW190425-like binaries exist in the Milky Way, LISA will detect them within the volume of our Galaxy and will measure their chirp masses to better than 10 per cent for those binaries with gravitational wave frequencies larger than 2 mHz. This work explores how we can probe a population of Galactic GW190425-like BNSs with LISA and investigate their origin. We assume that the Milky Way's BNS population consists of two distinct subpopulations: a fraction w1 that follows the observed Galactic BNS chirp mass distribution and w2 that resembles chirp mass of GW190425. We show that LISA's accuracy on recovering the fraction of GW190425-like binaries depends on the BNS merger rate. For the merger rates reported in the literature, $21{-}212\,$ Myr−1, the error on the recovered fractions varies between ∼30 and 5 per cent.


The feasibility of broad band fluorine decoupling for 13C NMR spectroscopy, employing a new composite pulse sequence, is shown. The application of this sequence allows the decoupling of fluorine nuclei over almost the total range of chemical shifts in fluoroorganic compounds, at magnetic fields of up to 2.3 T, without extensive demands on the decoupler power amplifier. The range of expected chemical shifts of fluorine bonded to carbons is briefly discussed.


The utility model provides a fluid leakage automatic-stopping device, comprising an electromagnetic valve, a flow meter and a microcomputer control panel, wherein the electromagnetic valve and the flow meter are arranged on a fluid pipeline, and electrically connected with the microcomputer control panel. The utility model can close the fluid in time, and then reduce the loss.

Let $P_I$ be the convex compact set of all unital positive linear maps between the matrix algebra over the complex field. We find a necessary and sufficient condition for which two maximal faces of intersect. In particular, we show that any pair of maximal faces of has the nonempty intersection, whenever .


In the mouse seminiferous epithelium four sites of formed microtubules (MTS) are axonemes and manchettes of spermatids, Sertoli-cell cytoplasm, and spindles of dividing cells. Various experimental treatments indicate that the manchette MTS are different from other formed MTS. Fixation in 1% osmium tetroxide yields good preservation of axonemal MTS, varying degrees of preservation of manchette MTS, but no preservation of spindle or Sertoli-cell MTS. Cell-suspension, and intact-tubule cultures subjected to 0–4°C or 50°C exhibit a breakdown of spindle and Sertoli-cell MTS while manchette and axonemal MTS remain intact. Cell suspensions exposed to Colcemid or colchicine show no MTS in Sertoli and dividing cells; axonemal MTS are unaffected while in the manchette there is an increase in cross-bridging between MTS. Cell suspensions treated for 120 minutes with vinblastine sulfate do not show MTS in the Sertoli cells, but crystals presumed to be microtubule protein are present after 15 minutes of exposure. Spindle MTS are dismantled but vinblastine-induced crystals are not present even after 120 minutes of exposure. The manchette MTS are dismantled by vinblastine in a proximal direction from their distal limits. This is accompanied by the formation of crystals of microtubule protein in the spermatid cytoplasm, while axonemal MTS are unaffected. Vinblastine and Colcemid used in combination cause the disruption of Sertoli-cell MTS after 15 minutes, spindle MTS after 30 minutes and formation of crystals after 60 minutes of exposure. The manchette MTS are disassembled, the pattern is disrupted and increased numbers of cross-bridges are seen. These findings indicate that the manchette MTS might be intermediate-type microtubules since they exhibit the reactions of both cytoplasmic and flagellar-type MTS.


Virtual laboratory is a practical teaching assisted instruction with high efficiency. This paper analyzes the characteristics, classification of virtual laboratory and the design of virtual instrument. It discusses the construction and system structure of network-based virtual laboratory. This paper also proposes design method of hardware and software, and provides a reference for the construction of virtual laboratory. Preface The famous American national instrument company (NI), first proposed the concept of software as an instrument of virtual instrument in the mid - 1980s(1). Virtual instrument is a kind of equipment which combines the hardware resources and the actual equipment together into a whole through the application of software, and completes the data display, data analysis processing and other functions through the software. Virtual laboratory is based on the technical support of computer hardware and software to realize the virtual environment and the virtual experimental methods(2). The real experimental environment and equipment and the experimental process that the virtual experiment reproduced ,provided the experimenter very real feeling, and it is easy to use, it has high efficiency, and not be limited by time and place, etc.The application of virtual laboratory allows students the freedom to experiment and realize data sharing. For the courses in the Science and Engineering Colleges or Universities, the experimental teaching is very important. The existing experiment teaching content and method have great limitations(3). There are some problems, such as time-consuming in management, decentralization of funds, backward equipment, low utilization of the laboratory, restriction of students' practice, etc. Virtual laboratory(1) can solve the problem effectively. In recent years, virtual experiment has become a product of information technology and computer network technology, it is the important means to improve science experiment mode and method(4), and it will be very helpful to improve the quality of experiment teaching. some universities and research institutions have established a certain scale specialized virtual laboratory, and received good effect. The construction and popularization of university virtual laboratory has become an inexorable trend of the future development.


This thesis begins with the problems which a practical information system faces, discusses how to deal with overall information security problems through several views and several layers, and gives us a special and overall scheme based on security technology and method. It concludes problems of design principal, integrated structure, integrated framework and so on. Especial to the key problems such as identity authentication, access control and data protection, we give a whole design scheme and implement method to illuminate it.


Voice over IP (VoIP) is increasingly replacing fixed line telephone systems globally due to lower cost, call quality improvements over digital lines and ease of availability. At the same time, criminals have also transitioned to using this environment, creating challenges for law enforcement, since interception of VoIP traffic is more difficult than a traditional telephony environment. One key problem for proprietary VoIP algorithms like Skype is being able to reliably identify and characterize network traffic. In this paper, the latest Skype version and its components are analyzed, in terms of network traffic behavior for logins, calls establishment, call answering and the change status phases. Network conditions tested included blocking different port numbers, inbound connections and outbound connections. The results provide a clearer view of the difficulties in characterizing Skype traffic in forensic contexts. We also found different changes from previous investigations into older versions of Skype.


Objectives. We investigated whether abnormal vaginal flora, including bacterial vaginosis (BV), are associated with detection of cervical HIV-1 RNA among HIV-infected women in Mozambique.
Methods. We obtained clinical data and vaginal specimens from HIV-infected women registering for their first visit at one of two HIV care clinics in Mozambique. We compared women with detectable cervical HIV viral load (≥40 copies/ml) with women with undetectable cervical HIV.
Results. We enrolled 106 women. Women with abnormal vaginal flora (intermediate Nugent scores, 4 - 6) were more likely to have detectable cervical HIV RNA then women with normal vaginal flora (adjusted odds ratio 7.2 (95% confidence interval 1.8 - 29.1), adjusted for CD4 count). Women with BV had a non-significantly higher likelihood of detectable cervical HIV than women with normal flora.
Conclusions. Abnormal vaginal flora were significantly associated with cervical HIV expression. Further research is needed to confirm this relationship.


Following the Open Data trend, governments and public agencies have started making their data available on the Web and established platforms such as data.gov or data.un.org. These Open Data platforms provide a huge amount of data for various topics such as demographics, transport, finance or health in various data formats. One typical usage scenario for this kind of data is their integration into a database or data warehouse in order to apply data analytics. However, in today's business intelligence tools there is an evident lack of support for so-called situational or ad-hoc data integration. In this demonstration we will therefore present DrillBeyond, a novel database and information retrieval engine which allows users to query a local database as well as the Web of Open Data in a seamless and integrated way with standard SQL. The audience will be able to pose queries to our DrillBeyond system which will be answered partly from local data in the database and partly from datasets that originate from the Web of Data.

We will show how such queries are divided into known and unknown parts and how missing attributes are mapped to open datasets. We will demonstrate the integration of the open datasets back into the DBMS in order to apply its analytical features.

A novel approach to the Boolean mapping problem is presented. It relies on a Boolean matching algorithm [TF96], which may take advantage of don't care conditions . For area minimization, the comparison with the structural matching approach used in SIS [Tou90] shows that the Boolean mapping achieve better results in similar computing time. We will show that low power technology mapping techniques like POSE [IP96b] may take advantage of this Boolean matching algorithm.


During the years 2020 and 2021, the effects of various biopesticides and the egg parasitoid Trichogramma chilonis on the okra shoot and fruit borer were investigated in open fields. All interventions outperformed over the untreated control. The entomopathogenic bacterium Bacillus thuringiensis was the most promising biopesticide tested, with the lowest shoot (5.49% and 6.87% in 2020 and 2021, respectively) and fruit damage (4.95% and 5.65% in 2020 and 2021, respectively), followed by the entomopathogenic fungi Beauveria bassiana (7.08%, 8.04% shoot damage and 6.78% and 6.73% fruit damage during 2020 and 2021, respectively). Interestingly, all biopesticides evaluated were shown to be safe for the polyphagous predators occurring in the okra habitat, such as the ladybird beetles Menochilus sexmaculatus and Micraspis discolour and the spiders Marpissa spp. and Oxyopes lineatipes. However, emamectin benzoate 5% SG was the most effective treatment in terms of minimizing okra shoot and fruit damage, resulting in a maximum percent reduction over control (PROC) (85.54 and 80.90 against shoot damage and 76.60 and 71.33 against fruit damage during 2020 and 2021, respectively). Each treatment's economics were also analysed. The experimental plots treated with emamectin benzoate had the highest cost:benefit ratio (1:11.16), while B. thuringiensis had the highest (1:7.06) among the biopesticide / parasitoid releasing plots.


As part of an ongoing UK-wide monitoring scheme, 100 Barn Owl (Tyto alba) carcases found in Scotland since 1983 have been analysed for second-generation anticoagulant rodenticides. These compounds have greater toxicity and persistence than the warfarin-like compounds they replaced. This enhances their potential for secondary poisoning of non-target organisms. Second-generation rodenticides were first detected in Scottish Barn Owls in 1990, and the proportion of birds containing at least one compound has varied between 15% and 45% in subsequent years. In total, 21% of birds have contained detectable amounts of rodenticide, a slightly (but not significantly) lower proportion than in England (30.1%) or Wales (24.5%). Introduction CEH Monks Wood, in collaboration with the Joint Nature Conservation Committee and the Environment Agency, has been running a Predatory Bird Monitoring Scheme (PBMS) since the mid-1960s. Raptor carcases sent in by members of the public are analysed for pesticides and industrial chemicals. As part of this scheme, Barn Owls have been analysed for the 'second generation' rodenticides which were introduced into Britain from the mid1970s onwards to combat the resistance of rats to first generation compounds such as warfarin. Second generation rodenticides include: Brodifacoum, (Havoc®, Klerat®, Talon®) Difenacoum, (Neosorexa®, Ratak®, Ridak®) Bromadialone (Maki®, Super Caid®, Lanirat®, Ratoban®) Flocoumafen (Storm®) Compared to warfarin-type compounds, second generation compounds are more toxic and residues are more persistent in the body. This enhances the potential for secondary exposure of non-target predators which are exposed either when they capture poisoned rodents that have not yet succumbed, or when they scavenge rodent carcases. Results & Discussion A total of 1,009 Barn Owl carcases received between 1982 and 2001 have been analysed for second generation rodenticides. These include 100 birds from Scotland, 753 from England and 94 from Wales; with no location details available for the others. The dataset comprised 25% adults, 67% juveniles, 50% males, 45% females; the age and sex could not be determined for all carcases. These owls had died from various causes, with road traffic accidents and starvation the main causes (Table 1). Twelve owls (1.2%) were diagnosed as having died as a result of secondary poisoning by second generation rodenticides. Typically, these birds had high rodenticide concentrations in the liver and characteristic signs of haemorrhaging, especially around the heart and lung. Table 1 The Cause of Death of Barn Owls Cause of Death Scotland England Wales % % % Accident 0 0 1 Disease 0 2 0 Drowned 0 1 0 Electrocution 0 0 0 Shot 0 1 0 Injury 0 1 0 Poisoned 1 1 1 Predated 1 3 0 Collision (including traffic accidents) 66 51 54 Starvation 26 34 39 Trapped 1 0 1 Unknown 5 6 4 Second generation rodenticides were first detected in Scottish Barn Owls in 1990 and the proportion of birds contaminated with at least one rodenticide has varied between 13% and 33% in subsequent years, with an overall average of 21% (Figure 1). A similar pattern was found in owls from Wales, while those from England showed a more consistent temporal increase. This increase reflects the rise in use of second generation rodenticides that has occurred throughout the UK, particularly during the 1980s.

The invention additionally relates to granulates obtained by using this method and to pharmaceutical dosage forms, which contain statins, especially cerivastatin, and which can be produced from said granulates.


An induction cold crucible melting is one of the most promising technology for the reuse and decontamination of the radioactively contaminated metallic materials generated during the dismantling of nuclear facilities, because the crucible ensures a long life operation without generating the secondary wastes. Based on the knowledge obtained through the fundamental study using the crucible of 45 mm in diameter, the MERC (Melting and Recycling of Metals by Cold Crucible) process was designed, manufactured and scaled up to 100-140 mm in diameter. Not only cylindrical sectional crucibles but also rectangular slab sectional crucibles were developed. The maximum power of the high frequency generator is 150 kW and the frequency is 25 kHz. In the MERC, either fragments of stainless steel or tubings and pipings with small section, which were the surrogates of contaminated metallic materials, were continuously supplied together with the flux for the decontamination, followed by melting in the crucible and pulling down by the precise withdrawal system ensuring the melt dome to be kept at a suitable level for the melting. The maximal withdrawal velocity employed was 12 mm/min. The ingot and slab were cut in every 300 mm length by the mechanical saw. They were automatically transported to the outlet of the equipment by the conveying system. Heat efficiency of the MERC was more than 26%. The ingot surface was smooth and crack free, facilitating the removal of radioactive elements concentrated in a slag stuck on the ingot surface. There was no macro segregation inside. Tracer elements of Sr and Hf transferred to the slag, Cs and Zn to the dust. Co and Mn mostly remained in the ingot. However, up to 10% of Co could transfer to the slag.

Objective: Depression affects nearly one in five Americans at some timein their life, causing individual suffering and financial cost. The Internethas made it possible to deliver telemedicine care economically to areasand populations with limited access to specialist or culturally and lin-guistically congruent care. Methods: This study compared the effective-ness for Hispanic patients of depression treatment provided by apsychiatrist through Internet videoconferencing (Webcam intervention)and treatment as usual by a primary care provider. Adults (N=167) witha diagnosis of depression were recruited from a community clinic andwere randomly assigned to treatment condition. Webcam participantsmet remotely each month with the psychiatrist, and treatment-as-usualpatients received customary care from their primary care providers, allfor six months. At baseline and three and six months, analyses of variancetested differences between conditions in scores on depression ratingscales and quality-of-life and functional ability measures. Results: Allparticipants experienced an improvement in depression symptoms.Ratings on the Montgomery-Asberg Depression Rating Scale by clini-cians blind to treatment group and self-ratings on the nine-item PatientHealth Questionnaire, Quality of Life Enjoyment and Satisfaction Ques-tionnaire, and Sheehan Disability Scale showed a significant main effect oftime. On all four measures, a significant interaction of time by interventionfavoring the Webcam group was noted. Discussion: Results suggest thattelepsychiatry delivered through the In ternet utilizing commercially avail-able domestic Webcams and standard Internet and computer equipmentis effective and acceptable. Use of this technology may help close the gapinaccesstoculturallyandlinguisticallycongruentspecialists.(PsychiatricServices 63:1213–1217, 2012; doi: 10.1176/appi.ps.201100274)


A thermal sensitivity analysis is performed for an Inverted-F antenna (IFA) at the worst-case thermal condition (reentry phase) of a typical sub-orbital sounding-rocket spaceflight. Electromagnetic simulations show that a 300 Celsius change in the IFA temperature, mainly caused by the aerodynamic heating, increases the reflected power by 1% and decreases the antenna gain by 2.5%. The results show that the degradation of antenna performance and the telemetry link quality is negligible. Therefore, the IFA is a good antenna choice for similar sounding rockets from the thermal reliability point of view


This paper examines the strategic choice between growth-oriented and profit-oriented strategies for emerging market firms. We develop and test hypotheses of how growth-oriented and profit-oriented strategic focus of emerging market firms affects their subsequent performance position in terms of achieving profitable growth. We contend that emerging market firms with a stronger focus on growth is less likely to achieve a position of high growth and high profitability in later stage. In contrast, a stronger focus on profit is more likely to achieve such a favorable position. We also examine the moderating effect of firm age on the proposed relationship. We test our arguments using a sample of Chinese firms between 2002 and 2009. Our study contributes important insights to strategic choices and performance for firms in emerging markets.


This paper analyzes how changes to the deductibility of state and local taxes under the federal personal income tax affect local fiscal outcomes. This paper is the first to study the impact of changing tax prices on local fiscal outcomes while allowing for local heterogeneity in tax incentives at the county level. Exploiting variation at the county level yields a more elastic relationship between tax price and local spending than using coarser units of observation. Simulations suggest that limiting the deduction for state and local taxes would not disproportionately hurt resource-poor areas, making such limits potentially progressive policy options.


This study looks at the relationship between the perception and production of Mandarin tones by non-native speakers studying Mandarin. This issue is first examined in terms of the relationship between the perception and production of speech, in general, and then in terms of Mandarin tone perception and Mandarin tone production. The subjects (N=33) were students studying Mandarin Chinese at the University of Hawai'i and were both native and non-native English speakers who neither spoke or heard Mandarin regularly outside of the classroom. Subjects were administered a three part "Mandarin Tone Test'' focusing on a) tone production, b) tone perception, and c) subject perception of their own tone production. 85% of the subjects perceived tones better than they produced the same tones. Further, subject perception errors appeared to be of two primary types: a) misidentification of a tone and b) identification of a tone according to incorrect tone features/boundaries. Overall, students showed global awareness of their tone production errors based upon subject tone "ratings". Finally, subject production, perception, and whole test mean scores increased corresponding to subject courselevel (1()()-, 2()()-, 4()()-).


This thesis has demonstrated how representations of disability are used to reaffirm or critique dominant power structures by examining dystopian children's texts from the late Victorian to the contemporary.


This book is a unique addition to the history of American states' ardent attempts to cope with their multicultural societies during the first five decades of the twentieth century. Rosemblatt, an established scholar of race and gender in Latin America, has produced a remarkable study of the U.S. and Mexico at a time when social sciences in both countries were growing, and state agencies in both nations made attempts to manage and aid vulnerable populations. Skillfully weaving the history of social science ideas and state policies aimed at indigenous people in early twentieth-century Mexico and the U.S., the author transcends comparison and provides a truly transnational study. Rosemblatt's goal is to study the efforts of social scientists "who worked with state officials to understand how to manage racial difference within and across nations" (3). The book has three sets of arguments, one for each nation and then a third about the relationship between the two. The author finds important distinctions between the two countries' intellectual perspectives and policy outcomes, even as scientific communities in each nation freely shared ideas. For example, in the U.S., the overarching goal was "sensitive" acculturation of indigenous people in the context of the overarching assumption that indigenous cultural expressions would "disappear" once no longer functional. Mexican scientists' energies, on the other hand, were largely devoted to documenting in great detail the cultural diversity in their nation, and they resisted generalizing theories. Finally, Rosemblatt convincingly demonstrates that Mexican scholarship influenced U.S. social science—in spite of the fact that scientists in both countries acknowledged the imbalance of power between the two. The book's chapter structure reflects Rosemblatt's third argument by subtly placing Mexico at its center—the story begins, and ends, there. That said, all the chapters carefully capture the interplay of scientists' ideas and professional engagement in and between both countries. The text is divided into two parts, organized chronologically, and each part has two chapters devoted to Mexico and the U.S. A rich introduction frames the book in terms of questions of policy formation and the recent history of scientific constructions of human difference. Part I, which comes after a substantial introduction that sketches the larger context in terms of eugenics and other scientific and policy themes, first takes


OBJECTIVES
Circulating proangiogenic haematopoietic cells (PHCs), including CD34+ cells, play an important role in endothelial homeostasis. Among PHCs, CD34+ cells are the largest cell population, thus, much of the regenerative/reparative potential of PHCs may be attributed to CD34+ cells. Our aim was to determine the association between inflammation and CD34+ cell number, intracellular levels of reactive oxygen species (ROS) and expression of Toll-like receptor 3 (TLR3) and interleukin 1β (IL-1β), arterial stiffness (AS) indices, and carotid intima-media thickness (cIMT) in patients affected by rheumatoid arthritis (RA).

METHODS
CD34+ cells were isolated from 24 RA patients and 26 matched controls. ROS levels, TLR3 and IL-1β expression were measured. C-reactive protein (CRP), fibrinogen, AS, and cIMT were also evaluated.

RESULTS
CD34+ count was lower in RA patients as compared to controls. In CD34+ cells from RA patients, ROS, TLR3 and IL-1β expressions were increased compared to controls. In RA patients, we found higher CRP and fibrinogen levels, and higher values of Pulse Wave Velocity (PWV) and Augmentation Index (AIx), both AS indices, and of cIMT. CD34+ cell numbers were inversely correlated with CRP, TLR3, IL-1β, ROS, and AS indices. TLR3 levels were related to CRP, IL-1β, fibrinogen and ROS. IL-1β levels were correlated with expression of CRP, ROS, and PWV.

CONCLUSIONS
Inflammatory status in RA is associated with an increased expression of TLR3 and of IL-1β in CD34+ cells, which appear to affect cell number. These new findings suggest a perspective on accelerated atherosclerosis and vascular damage in RA.

Description of a new species, Diploglottis bracteata Leenh., from Queensland, Australia. Reduction of Euphorianthus (E. Malesia) to Diploglottis (NE. Australia). Discussion of the occurrence of actinomorphic and zygomorphic flowers in the Sapindaceae in nearly all tribes and even within ten genera. Discussion of the systematic position of Diploglottis bracteata: this species seems distinctly allied to and more derived than the New Caledonian genus Storthocalyx, and thus may belong to an old element of the Queensland flora allied with that of New Caledonia. On the other hand, D. bracteata is within Diploglottis closest to the East Malesian species, whereas the further Australian species are distinctly more derived. They may belong to a younger element in the Queensland flora of Malesian derivation.


We present a case study of the flank magnetosheath crossing by the Spektr-R satellite. High time resolution measurements of the ion flux value and its direction provided by the BMSW (Fast Solar Wind Monitor) instrument are examined at different distances from the magnetosheath boundaries – the bow shock and the magnetopause. The magnetosheath behind the quasi-perpendicular bow shock is analysed. The time resolution of these data – 31 ms – is sufficient for observing the frequency spectra of plasma fluctuations both at the magnetohydrodynamics (MHD) and ion kinetic scales. Generally, MHD scales are characterised by Kolmogorov-like spectra ${\sim}f^{-5/3}$
 while spectra at kinetic scales are steeper with a break existing between the two scales. We examine evolution of spectral parameters such as power density and slopes, and the break frequency together with the evolution of properties of the probability distribution function. We find out that (i) power spectral densities of the two quantities change differently toward the magnetosheath (MSH) boundaries, (ii) the spectra slopes do not change significantly across the magnetosheath, (iii) the break frequency of the spectrum changes toward the magnetopause. In the middle MSH the spectra are affected by instabilities supposed to be ion cyclotron instabilities. We demonstrate that the plasma is low intermittent in the middle MSH and highly intermittent near its boundaries in the absence of large-scale variations.

BACKGROUND
 Government public communication during the COVID-19 pandemic in the form of Twitter messages has a potential role in influencing the public response to the pandemic. Understanding the collective efforts by governmental ministries is vital in recognizing the mechanisms, by which the use of Twitter for governmental communication was expected to guide appropriate coordinated actions.

 OBJECTIVE
 To examine topics related to COVID-19 posted by Saudi governmental ministries on Twitter by conducting a content analysis. We also aim to further analyze the generated topics by situating our findings within the Saudi context and existing health behavior theoretical frameworks.

 METHODS
 We performed a retrospective content analysis of COVID-19 related tweets. On November 7th, 2020 we extracted relevant tweets posted by five Saudi governmental ministries. Our study was conducted in three phases: (1) data extraction, preparation, and transformation (2) coding schema development and application, and (3) analysis. To give context to the generated topics we considered the COVID-19 pertinent social events in Saudi Arabia and divided the social events into four phases according to the Crisis, Emergency, Risk Communication (CERC) Rhythm. We used constructs of key health behavioral theories to further examine the "empowerment" category.

 RESULTS
 A total of 3,950 tweets were included in our dataset. Topics fell into two groups: disease related (49.2%) and non-disease related (50.8%). The disease-related group included seven categories: awareness (18.5%), symptom (0.6%), prevention (7.7%), disease transmission (1.9%), treatment (0.3%), testing (3.4%), and reports (16.7%). The non-disease related group included eight categories: lockdown (5.9%), online learning (12.8%), digital platforms (4.3%), empowerment (12.0%), accountability (1.1%), non-disease reports (2.1%), local and international news (10.8%), and general statements (1.9%). Based on the correlation analysis, we found that the top positively correlated categories were: "testing" and "digital platforms" (r = 0.4157), "awareness" and "prevention" (r=0.3088), "prevention" and "disease transmission" (r=0.3025), "awareness" and "disease transmission" (r=0.1685), "symptom" and "testing" (r=0.1081), "awareness" and "symptom" (r=0.0812), "symptom" and "digital platforms" (r=0.0645), and "disease transmission" and "digital platforms" (r=0.0450), p-values < 0.01. Within the Saudi context as it relates to CERC, "awareness" was the top frequent category during the "preparation" and "maintenance" phases, while "empowerment" was the top category during the "initiation" phase and "online learning" was the top category during the "resolution" phase. There was a number of health behavior theoretical constructs linked to our findings including: perceived benefits, perceived severity, perceived behavioral control, observational learning, incentive motivation, self-efficacy, collective efficacy, and facilitation.

 CONCLUSIONS
 Social media platforms can be utilized as powerful tools to communicate with the public during a health crisis. Integrating behavioral theories in the development of health risk communication should be taken seriously by government communication specialists who manage social media accounts, as these theories help underlining determinants of people's behaviors.


Does reading a lot lead to better reading skills, or does reading a lot follow from high initial reading skills? The authors present a longitudinal study of how much children choose to read and how well they decode and comprehend texts. This is the first study to examine the codevelopment of print exposure with both fluency and comprehension throughout childhood using autocorrelations. Print exposure was operationalized as children's amount of independent reading for pleasure. Two hundred children were followed from age 5 to age 15. Print exposure was assessed at ages 5, 7, 8, 9, and 13. Prereading skills were tested at age 5 and reading skills at ages 7, 8, 9, 14, and 15 (the latter with the Programme for International Student Assessment [PISA]). Before children learned to read (i.e., age 5), prereading skills and print exposure were not linked. Path analyses showed that children's print exposure and reading skills reciprocally influence each other. During the early school years, the effects run from reading fluency to comprehension and print exposure, so from skills to amount. The effect of accumulated practice only emerged in adolescence. Reading fluency, comprehension, and print exposure were all important predictors of age 15 PISA reading comprehension. These findings were largely confirmed by post hoc models with random intercepts. Because foundational reading skills predicted changes in later reading comprehension and print exposure, the authors speculate that intervening decoding difficulties may positively impact exposure to and comprehension of texts. How much children read seems to matter most after the shift from learning to read to reading to learn.


Electrolysis of iodosilanes with Al/Pt electrodes in pivalonitrile results in the formation of the Si–Si bonds to give the corresponding disilanes. On the other hand, the electrolysis of various halosilanes such as iodo-, chloro-, and fluorosilanes with Pt/Pt electrodes in the presence of phenylacetylene leads to the formation of the Si–sp-carbon bonds to give phenylethynylated products.


Every field has skeletons in their closet. One of the skeletons of single molecule biophysics is the persistence length of short DNA molecules. Loosely speaking, the persistence length, P, is a statement about the elasticity of a polymer; an infinitely stiff polymer has an infinite P. Knowledge of the persistence length of DNA and RNA is essential to design and interpret single-molecule experiments. Two models of polymer elasticity constitute the theoretical bedrock of the field: the freely-jointed chain and the wormlike chain (WLC). In this issue, Seol et al. (1xElasticity of short DNA molecules: theory and experiment for contour lengths of 0.6–7 μm. Seol, Y., Li, J., Nelson, P., Perkins, T.T., and Betterton, M.D. Biophys. J. 2007; 93: 4360–4373Abstract | Full Text | Full Text PDF | PubMed | Scopus (61)See all References(1) extend the classic WLC model in a way that will be immediately useful to experimentalists working on a multitude of systems.The story starts in the early 1990s, when it became possible to experimentally characterize the elasticity of single DNA molecules. In 1994, Bustamante et al. (2xEntropic elasticity of λ-phage DNA. Bustamante, C., Marko, J.F., Sigga, E.D., and Smith, S. Science. 1994; 265: 1599–1600Crossref | PubMedSee all References(2) reported that force extension curves of λ-DNA beautifully fit the WLC model. Despite λ-DNA having a finite length (97 kb) and clearly not being an ideal polymer, a continuum elastic theory such as the WLC captured its elasticity surprisingly well. Right from the beginning, however, it was apparent that we should not expect the WLC to faithfully represent all DNAs in all situations. Even in the first article there were hints of the stretchable solid regime at forces above ∼10 pN, and at even higher forces the DNA suddenly overstretched (3xOverstretching B-DNA: the elastic response of individual double-stranded and single-stranded DNA molecules. Smith, S.B., Cui, Y.J., and Bustamante, C. Science. 1996; 271: 795–799Crossref | PubMedSee all References(3), another clear departure from the WLC model.Nonetheless, one thing was sacred: the persistence length of DNA. The persistence length certainly did depend on ionic strength, pH, and intercalators (3.xOverstretching B-DNA: the elastic response of individual double-stranded and single-stranded DNA molecules. Smith, S.B., Cui, Y.J., and Bustamante, C. Science. 1996; 271: 795–799Crossref | PubMedSee all References, 4.xIonic effects on the elasticity of single DNA molecules. Baumann, C.G., Smith, S.B., Bloomfield, V.A., and Bustamante, C. Proc. Natl. Acad. Sci. USA. 1997; 94: 6185–6190Crossref | PubMed | Scopus (552)See all References, 5.xThe effect of pH on the overstretching transition of double-stranded DNA: evidence of force-induced DNA melting. Williams, M.C., Wenner, J.R., Rouzina, I., and Bloomfield, V.A. Biophys. J. 2001; 80: 874–881Abstract | Full Text | Full Text PDF | PubMedSee all References), but incoming graduate students were told that P captured an intrinsic property of DNA and did not depend on the polymer's length. Most practitioners suspected that this was not true, since the concept of a persistence length becomes ill-defined when the polymer is not much longer than P. Moreover, many experimental studies of short pieces of DNA revealed that it was more compliant than predicted from the classic WLC parameterized with the canonical value of P, 50 nm.What we did not know was how P depends on the contour length, and when we need to explicitly incorporate finite L effects in our models and experiments. This is what makes the finite-WLC of Seol et al. so useful—this extension of the classic WLC includes three effects critical to experiments: the finite length of the chain, rotational fluctuations of the bead, and the boundary conditions at the polymer's anchor points.As described by Seol et al., there are two equivalent ways of applying the finite-WLC to force-extension curves. Experimental data can be fit directly to the finite-WLC, or the data can be fit to the classic WLC, and all the complexity can be dealt with by correcting P for the effects discussed above. The former approach is conceptually more elegant, and the latter approach is mathematically simpler and is easy to plug into existing data-processing scripts.Out of curiosity, I compared the performance of the classic WLC to the finite-WLC using some single-molecule RNA unfolding data (6xReversible unfolding of single RNA molecules by mechanical force. Liphardt, J., Onoa, B., Smith, S.B., Tinoco, I. Jr., and Bustamante, C. Science. 2001; 292: 733–737Crossref | PubMed | Scopus (565)See all References(6), and I found that the finite-WLC does rather well. The article of Seol et al. contains extensive experimental results that establish the performance of their finite-WLC.Is the finite-WLC the end of the story? Fortunately not—a multitude of essential biological processes take place on length scales far below one persistence length, and we are only beginning to understand the intricacies of DNA and RNA elasticity on short and very short scales. Nonetheless, the finite-WLC gives us a glimpse of what future models of DNA elasticity will look like. Not only that, but Seol et al. also gives us a blueprint for constructing elasticity models for specific experimental geometries and length scales.

The recognition and perception of faces – both alone and in groups – is an important biological function, enabling humans to effectively engage with one another socially. This thesis describes viewpoint and identity interactions in processing face ensembles, helping vision scientists to understand the cognitive mechanisms taking place. I manipulated viewpoint or identity across two experiments. The first experiment had participants report an average or single viewpoint or identity, and the second experiment had participants report an average identity or a single identity across a wide range of viewpoints. I find that efficiency in average – but not single – identity extraction decreases as viewpoints are progressively non-frontal. Viewers also extract summary viewpoint better than a single viewpoint, and this ability also decreases as global viewpoints are non-frontal. The implications in the face ensemble processing system, general ensemble processing models, and future research are discussed below.


Cytogenetic methods such as chromosome banding and in situ hybridization remain relevant in the post-genomic era, especially for allopolyploid species where genome duplication in some cases makes it difficult to assess the reorganization of chromosomes during evolution. In this review, we give a brief description of cytogenetic methods for the analysis of homoeological chromosomes in cereals. Emphasis is placed on the development of methods for the study of polyploid wheat and its progenitors and on tandem repeats and retrotransposons as markers to evaluate chromosome reorganiza- tion throughout evolution and breeding. The most effective cytological probes used for the identification of chromosomes in wheat and Triticeae species by fluorescence and genomic in situ hybridization are described. Particular attention is paid to ribosomal genes used as markers in phylogenetic studies and for chromosome identification. Utility of these cytogenetic methods in the evaluation of breeding lines is demonstrated. A strategy for cytological analysis of wheat hybrids according to the degree of relationships between the species involved in crosses is also discussed.


Inorder to identify the biologically relevant gene module and also which are the genes responsible for causing a disease,we use Biclustering technique which is also a useful co-clustering technique.In this paper, we present a exceptional method to state specific gene modules and also functionally related gene modules which are the reason for disease causing ,by applying a genetic algorithm to genetic data which is in the form of microarray data. To detect these differentially expressed gene modules, the anticipated method finds biclusters in which genes are overexpressed or under expressed, and also which  are differentially-expressed in the samples of genetic data. Inorder to get the differentially expressed we perform three steps in which we use K means alogorithm for clustering and Cheng and Chruch algorithm for biclustering. As to overcome the drawbacks in clustering  we use Biclustering technique which reduce redundancy in the data.The ensuing gene modules uncover preferable exhibitions over near techniques in the GO (Gene Ontology) term enhancement test and an analyzed association between gene modules and infection.

Abstract The hypothesis that two known chelators deferiprone (L1) and deferasirox (DFS) might be more efficient as combined treatment than monotherapies in the mobilization of copper was tested in copper-exposed rats. Male Wistar rats were exposed to 70 mg/kg body weight copper (II) chloride in drinking water for 42 d, followed by treatment with DFS (60 mg/kg body weight, oral, once daily), L1 (60 mg/kg body weight, oral, once daily) either alone or in combination DFS + L1 (30 mg/kg body weight, oral, once daily), for 10 consecutive days. After chelation therapy, these rats were anesthetized by ether vapor and immobilized by cervical dislocation. Then their heart, kidneys, liver and intestine were sampled for determination of copper, iron and zinc concentration with an atomic absorption spectrophotometer. The treatment with DFS and L1 appreciably decreased the depletion of endogenous copper, but the combined treatments were more efficient than the individuals in restoring the tissue copper levels. Furthermore, iron and zinc concentration after chelation therapy significantly decreased, thus consumption of iron and zinc tablet is recommended to return iron and zinc level to its normal state. Our results support the usefulness of this animal model for preliminary in vivo testing of copper chelators. The result of combined chelators treatment should be confirmed in a different experimental model before extrapolation to other systems.

Objectives: This paper evaluated whether a 2-item assessment of alcohol use risk, developed by the National Institute on Alcohol Abuse and Alcoholism (NIAAA SG), prospectively predicted smoking status among a sample of adolescents visiting their primary care physician. Methods: We analyzed a sample of 651 adolescents (57.80% female; 56.53% Hispanic, 22.73% African American, 14.44% White, 6.30% other) who completed the NIAAA SG at a baseline appointment and were assessed for future smoking risk. We obtained prospective data on smoking status using data from the 6-month post-baseline follow-up assessment. Results: Logistic regression analyses revealed that adolescents who were identified as at risk by the NIAAA SG were more likely to report smoking within 6 months. However, the association between the NIAAA SG and future smoking status became non-significant after controlling for future smoking risk measured at baseline. Conclusions: Questions that ask about past smoking and future smoking intentions are best used to screen adolescents in primary care for smoking risk.


Road traffic accident is the most prolific cause of death and injury to which developed countries are exposed. Even if accident rates are continuously decreasing, year by year, everywhere they generally remain at an inacceptable level for both human and economic reasons. Many efforts have been devoted to quantify the influence of various factors on the accident. From this knowledge policies and actions aiming at reducing accident numbers (or at least their severity) have been defined and implemented. Among influencing factors it has been recorded that weather is one of the most sensitive: accident rates in wet conditions are significantly higher than those in dry conditions. This paper addresses this last point. It is based upon a literature survey of published papers concerned with this problem. Results of the analysis with regard to the Excess Risk Coefficient in wet conditions and the relationship between wet road traffic accidents and road surface wet skidding resistance are presented. Then, conclusions and comments are drawn from this analysis. For the covering abstract see ITRD E116488.


The United States (U.S.) nuclear industry, like similar process control industries, has moved toward upgrading its control rooms. The upgraded control rooms typically feature digital control system (DCS) displays embedded in the panels. These displays gather information from the system and represent that information on a single display surface. In this manner, the DCS combines many previously separate analog indicators and controls into a single digital display, whereby the operators can toggle between multiple windows to monitor and control different aspects of the plant. The design of the DCS depends on the function of the system it monitors, but revolves around presenting the information most germane to an operator at any point in time. DCSs require a carefully designed human system interface. This report centers on redesigning existing DCS displays for an example chemical volume control system (CVCS) at a U.S. nuclear power plant. The crucial nature of the CVCS, which controls coolant levels and boration in the primary system, requires a thorough human factors evaluation of its supporting DCS. The initial digital controls being developed for the DCSs tend to directly mimic the former analog controls. There are, however, unique operator interactions with a digital vs. analog interface, and more » the differences have not always been carefully factored in the translation of an analog interface to a replacement DCS. To ensure safety, efficiency, and usability of the emerging DCSs, a human factors usability evaluation was conducted on a CVCS DCS currently being used and refined at an existing U.S. nuclear power plant. Subject matter experts from process control engineering, software development, and human factors evaluated the DCS displays to document potential usability issues and propose design recommendations. The evaluation yielded 167 potential usability issues with the DCS. These issues should not be considered operator performance problems but rather opportunities identified by experts to improve upon the design of the DCS. A set of nine design recommendations was developed to address these potential issues. The design principles addressed the following areas: (1) color, (2) pop-up window structure, (3) navigation, (4) alarms, (5) process control diagram, (6) gestalt grouping, (7) typography, (8) terminology, and (9) data entry. Visuals illustrating the improved DCS displays accompany the design recommendations. These nine design principles serve as the starting point to a planned general DCS style guide that can be used across the U.S. nuclear industry to aid in the future design of effective DCS interfaces. « less

It starts with a brief review of the North American tradition of research on the topic. In the second part, I analyze potentials and limits associated with assuming school discipline and classroom management as a research field in Brazil, using as parameters the papers published in Brazilian academic events like ANPEd annual meetings between 2007 and 2011 and the seminar on Indiscipline in the Contemporary School. The third part approaches the relationship between classroom management, as professional knowledge, and teacher education in Brazil. The last part is devoted to the final remarks.


In 1965, Helen Gurley Brown (1922–2012) assumed the top editing job at Cosmopolitan and transformed it from a failing title into one of magazine publishing's greatest successes. During an era of increasing publication specialization, Cosmopolitan was one of the few magazines to target and celebrate women's growing economic and social independence. Much of the scholarship on and critical appraisals of Brown and Cosmopolitan have focused on sexual politics and issues of taste. This paper takes an institutional approach by examining Brown's professional practices and how they contributed to Cosmopolitan's growth, profitability, and popularity: know your reader and always keep her in mind, prioritize good writing, and accommodate corporate and advertiser interests. In addition, it acknowledges Brown's role as a visionary editor and businesswoman, as well as Cosmopolitan's importance in magazine history.

Internet of Things (IoT) is currently an emerging trend in the industry and is proving to be the driving force in the field of research and development. Due to a growing demand in industries for a cloud-based solution and easy integration with existing hardware devices, IoT has become a popular choice among all verticals of industry: Engineering, Manufacturing, Accounts, Supply Chain and many more. This paper was a result of a project whose requirement was realtime detection for liquid levels in a chemical plants using a wireless GoPro Camera. The most obvious choice was OpenCV, and this would have been the most common solution. But a complete IOT based solution is proposed that would not only detect level but will also provide additional features like cloud storage, alert messages and Convolutional Neural Network (CNN) based level corrections.

Bacterial infections are responsible for considerable morbidity and mortality in patients with chronic lymphocytic leukemia.1-6The nature of the defects in host resistance to bacterial infections in this disease have not been clearly defined. In our experience, absolute granulocyte counts are normal or only slightly decreased throughout most of the course of chronic lymphocytic leukemia. The polymorphonuclear response to inflammation in chronic lymphocytic leukemia is usually normal,7,8and the phagocytic function of the polymorphonuclear cells is normal.9,10Thus it appears that the majority of infectious complications result from factors other than qualitative or quantitative abnormalities of the polymorphonuclear leukocytes. Since the introduction of serum protein electrophoresis, several investigators have noted hypogammaglobulinemia, often of a severe degree, in patients with chronic lymphocytic leukemia.11-25Creyssel et al.19have reported a good correlation between bacterial infections and hypogammaglobulinemia in this disease. A decreased or absent circulating antibody response following antigenic stimulation has also


Abstract The purpose of this study was (a) to compare the power of the body, as measured by the product of jumping height and body weight, with the strength of leg and thigh flexor muscles and with the strength of leg and thigh extensor muscles; and (b) to compare the effect on power of strength development of agonistic and antagonistic muscle groups. Prior to the training programs, significant correlations of .52 between flexion-strength and power scores and .65 between extension-strength and power scores were obtained for the total experimental group. At the completion of the experiment, nonsignificant correlations were obtained between gain scores for the same measurements. All training groups increased significantly in flexion strength, extension strength, and power during the experimental period. The strength-development programs used in this study were found to be equally effective as means of increasing power.


The emergence of wind energy as a potential alternative to traditional sources of fuel has prompted notable research in recent years. One primary factor contributing to efficient utilization of wind energy from a wind farm is the type of turbines used. However, selection of a specific wind turbine type is a difficult task due to several criteria involved in the selection process. Important criteria include turbine's power rating, height of tower, energy output, rotor diameter, cut-in wind speed, and rated wind speed. The complexity of this selection process is further amplified by the presence of conflicts between the decision criteria. Therefore, a decision is desired that provides the best balance between all selection criteria. Considering the complexities involved in the decision-making process, this paper proposes a two-level decision turbine selection strategy based on fuzzy logic and multi-criteria decision-making (MCDM) approach. More specifically, the fuzzy arithmetic mean operator is used in the decision process. The proposed approach is applied to wind data collected from the site of Qassim, Saudi Arabia. Results indicate that the proposed approach was effective in finding the optimal turbine from a set of 20 turbines of various capacities.


The reservoir ability of coal rocks is controlled by both sedimentary facies and diagenesis.Sedimentary facies controls the content of ash and microcomponents of coal rocks,which further affect the reservoir ability of coal beds.There exists quantitative relation between the ash production rate and the porosity and permeability of coal.The more the ash,the lower the porosity and permeability of the coal.Among microcomponents of coal rocks,vitrinite is favorable to formination of cleat,which can enhance the permeability of the coal.The more the vitrinite in the coal,the higher the porosity and permeability.The content of vitrinite and ash are different in different types of coals.From dull coal to bright coal,vitrinite tends to increase,the ash tends to decrease,and the porosity and permeability tend to increase.In the study area,coals were deposited in tidal flats and delta environments.Due to difference in ash content and micro components,coals formed in tidal flats show higher porosity and permeability than those formed in deltas,and those formed in lower delta plain show higher porosity and permeability than those formed in upper delta plain.In addition,due to dissolution of the calcite cement filling fissures,cleats and pores,coal rocks in the vadose and phreatic zones show better reservoir ability,while deeply buried coal beds,due to cementation and compaction,show poor reservoir ability.


A current-based sensorless sliding mode control for induction motors is presented in this paper. It guarantees asymptotic tracking of prespecified speed and square of the rotor flux magnitude references without mechanical sensors. The problem of chattering, typical of sliding mode controllers, is overcome since the derivative of the stator currents are used as discontinuous forcing actions, while the actual control signals are continuous, thus limiting the mechanical stress. The proposed adaptive sliding mode speed observer is based on a different approach with respect to the widely used equivalent control techniques.


The NAD+ glycohydrolase-catalysed transglycosidation reaction of pyrido-annulated triazole 1 and imidazole 2 was investigated. In both cases two regioisomers, N1-ribosylated (3 and 5) and N3-ribosylated products (4 and 6), were efficiently obtained in roughly equal ratio. The regioisomers were distinguished from each other on the basis of 15N-NMR data. The present study furnished evidence of two competitive sites of transglycosidation in the triazole 1 and the imidazole 2. The occurrence of competition is probably attributable to a tautomeric equilibrium between 1a and 1b (2a and 2b).

Brazilian scholars, politicians, legal practitioners, and judges consistently refer to Brazil as a lay state, suggesting a type of secularism similar to French laïcité. However, in practice, the interaction between government, religion, and society in Brazil more closely resembles religious freedom in the United States. Among the twenty-six most populous countries, Brazil has the lowest governmental restrictions on religious freedom. The Brazilian government protects religious liberty through extensive constitutional and statutory provisions, as well as numerous international conventions. Notwithstanding these governmental protections, the country has recently experienced a dramatic increase in social hostilities directed toward people of faith. Thus, while Brazil is an example to the world with regard to minimal governmental restrictions on religious liberty, both the government and Brazilian citizens must find ways to minimize social hostilities and religious intolerance. This paper compares religious liberty in Brazil to French laïcité and U.S. religious freedom, explores governmental protections of religion in Brazil, exposes the growth of social hostilities towards religious groups in Brazil, highlights the work of government and grassroots organizations to turn back this rising tide of religious intolerance, and offers several suggestions on how the Brazilian government might further decrease social hostilities.


Post Me_New Id is an action research project with a focus on the future of the body. In 2007-09 a collaboration between body>data>space (London, UK),
CIANT (Prague, Czech Republic) TMA | Trans Media Academy (Dresden, UK) and KIBLA (Maribor, Slovenia) looked to examine the complexity of 21st century European human identity – with an exploration of the evolution of cyborg culture through technologies of the body, supported by the EU Culture 2007-2013 programme. The 4 organisations worked closely together to identify and investigate the challenges this poses to contemporary creation and the emergent artistic practices. The final output from this project is a Book and DVD combo containing essays and reflections from many of the artists involved in this eighteen month project plus the keynotes and panel conversations resulting from the Post Me_New ID Forum at CYNETart_08 in Dresden. The focus was particularly engaged in Multi-Identities and Networked Creation Processes in today's world.

Studies about pet ownership have found higher psychological health in those who own pets (Straede & Gates, 1993), as well as a relationship between attachment to a pet and feelings of support (Stammbach & Turner, 1999). The present study was designed to expand on previous research and to specifically examine the relationship between pet ownership and stress in college students. Two hypotheses were tested. Hypothesis 1 was that college students who own pets will perceive less stress. Hypothesis 2 was that the perceived level of stress would correlate negatively with the level of attachment to a pet. Participants were 135 students who completed the Perceived Stress Scale (Cohen, Karmack, & Mermelstein, 1983). Sixty-three students qualified via pet ownership and completed the Companion Animal Bonding Scale (Poresky, Hendrix, Mosier & Samuelson, 1987). The majority of participants were female, Caucasian, and 18-19 years of age. Statistical analyses did not provide significant support for either hypothesis 1 or 2. Based on these results, it appears that additional research is needed to further explore the potential impact of pet ownership on the perception and response to stress. PERCEIVED STUDENT STRESS 5 Perceived Student Stress in Relation to Attachment Theory with Pets Attending college comes with a variety of stressors (Roberti, Harrington, & Storch, 2006). In fact, stress among college students has increased in severity in recent years (Benton, Robertson, Tseng, Newton, & Benton, 2003). Stress is also associated with a number of health risks including a higher risk for cardiac events (Rosengren et al., 2004) and metabolic issues (Anderson, et al., 2002). In 2010, a 35-year longitudinal study indicated that psychological stress can increase the risk of dementia in older populations (Johansson, et al. 2010). Other issues surrounding long-term stress according to The American Institute of Stress, a non-profit organization, include an increase in the risk of asthma, weight gain, diabetes, headaches, depression, gastrointestinal problems, sexual dysfunction, and even a weakened immune system. All of these symptoms are debilitating to individuals, and when it comes to college student in particular, stress can also lead a student to doing poorly on academics or dropping out of school (Resko, 2017). Studies surrounding pet ownership have found higher psychological health in those who own cats (Straede & Gates, 1993), and that the more attached one feels to a pet the more support they feel as well (Stammbach & Turner, 1999). Physically, pet ownership is also associated with lower drug use and a decrease in illness related symptoms (Akiyama, Holtzman, & Britz, 1987). Furthermore, pets have been shown to improve mood (Becker, 1999), and owning a pet may "moderate the anxious/avoidant attachment style" (Quinn, 2005, p.1). Recent research has also documented that people are just as likely to experience the same kind of stress relief from owning an animal as they are to listen to music or participate in a pleasant activity (Kleiber & Adamek, 2012). With the numerous psychological and health benefits relating to pet ownership, PERCEIVED STUDENT STRESS 6 it is important for mental health professionals working with college students to explore how pet ownership may impact their client's stress levels. The goal of the current study is to explore the relationship between the level of attachment to a pet and student stress. Hypothesis 1 is that students who own pets will perceive less stress than their peers who do not own pets. Additionally, hypothesis 2 is that the level of stress will correlate negatively with the level of attachment to a pet. Attachment Theory and Animals


SI 2 G (Geographical Intelligent Information System) is a spin-off company of Marche Polytechnic University (Ancona, Italy), built up in 2008 by a cross-curricular team belonging to the Engineer faculty. GI-Thema project is developed by SI 2 G as ICT service and solution provider ranging from Remote Sensing and landscape monitoring (in particular Land Cover/Land Use mapping) to up-to-date computer cartography, Web-GIS solutions and Geographic Information Systems. The GI-Thema project goes into the landscape monitoring providing new automatic approaches, based on machine learning and image processing techniques and allowing to update geographic information in short time and high accuracy. According to this project, T-MAP software is developed inside the uDiG GIS environment and organized into an user friendly modular structure that allows to enhance and widen its performance in particular in terms of landscape classification (automated hybrid land cover mapping tool) and change detection analysis in general (i.e. automated road detection tool and network updating). Moreover, thanks to the uDiG environment, the GIS interoperability is achieved by the T-MAP software which is able to handle raster, shape and tabular data, facilitating the change detection analysis and its use as a valid GIS decision support system. In particular, to fulfill automated land cover mapping, T-MAP combines the pixel-based and object- based approaches into a hybrid classification solution that makes use of a segm entation tool and a rule-based thematic categorization. The output is a thematic map (Land Cover/Land Use) characterized by a good performance and a custom-designed legend. T-MAP's strong point is also a detailed accuracy assessment by means of stability maps and ad-hoc indexes that help the user to recognize stable regions from the instable ones which should be verified before being used. Lastly, as an example of change detection analysis, T-MAP road tracking tool is presented and it is shown its performance in presence of occlusion (e.g., shadows, cars, trees).


Recent detailed simulations have shown that an insufficiently accurate characterization of the contamination of unresolved polarized extragalactic sources can seriously bias measurements of the primordial cosmic microwave background (CMB) power spectrum if the tensor-to-scalar ratio r ∼ 0.001, as predicted by models currently of special interest (e.g., Starobinsky's R2 and Higgs inflation). This has motivated a reanalysis of the median polarization fraction of extragalactic sources (radio-loud AGNs and dusty galaxies) using data from the Planck polarization maps. Our approach, exploiting the intensity distribution analysis, mitigates or overcomes the most delicate aspects of earlier analyses based on stacking techniques. By means of simulations, we have shown that the residual noise bias on the median polarization fraction, Πmedian, of extragalactic sources is generally ≲0.1%. For radio sources, we have found Πmedian ≃ 2.83%, with no significant dependence on either frequency or flux density, in good agreement with the earlier estimate and with high-sensitivity measurements in the frequency range 5–40 GHz. No polarization signal is detected in the case of dusty galaxies, implying 90% confidence upper limits of Πdusty ≲ 2.2% at 353 GHz and of ≲3.9% at 217 GHz. The contamination of CMB polarization maps by unresolved point sources is discussed.

The Ganil facility is drastically extending its possibilities with new projects, so increasing its capabilities in nuclear physics. The most significant one is the Spiral2 installation based on a linear accelerator, then to be associated with the S3, NFS and DESIR new experimental rooms. Beside of the legacy homemade control system handling the original installation, Epics was chosen as the basic framework for these projects. First, some control system components were used during preliminary beam tests. In parallel, the whole architecture was designed while the organization for future operation started to be considered; also, more structured and sophisticated tools were developed and the first high level applications for the whole machine tuning started to be tested, jointly with the current onsite beam commissioning. Progression of the control system development is presented, from the first beam tests up to the whole Spiral2 commissioning. Then, according to the new projects to cope with, some highlights are given concerning the related organization as well as specific items and developments to be considered, taking benefit from the Spiral2 control system feedback experience. OVERVIEW OF THE GANIL FACILITY... The Ganil ("Grand Accélérateur National d'Ions Lourds") facility has quite yet a long history as the first beam was delivered to physicists in January 1983. It's a heavy ions accelerator complex devoted to nuclear and atomic physics, astrophysics, material science and radiobiology. The original installation consisted of several cyclotrons in cascade for accelerating the beam and, in 2001, was enhanced by the Spiral ("Système de production d'Ions Radioactifs Accélérés en Ligne") extension so that both stable and radioactive beams were able to be produced (see Figure 1). Figure 1: The Ganil facility. In order to extend to increase the range and quality of exotic nuclei to be delivered, the Spiral2 project was approved in May 2005 [1] and is presently within the commissioning phase [2]. It is based on a superconducting linac delivering up to 5 mA proton or deuteron beams or 1 mA q/a>1/3 ions beams. The project also includes the experimental rooms named S3 ("Super Separator Spectrometer") and NFS ("Neutrons For Science") and, as a continuation, the low energy RIB experimental hall DESIR ("Desintegration, Excitation and Storage of Radioactive Ions"). ... AND ITS CONTROL SYSTEMS As well as the machine itself, control systems strongly evaluate according with time and emerging technologies but always having to take into account the existing solutions. The initial control system was based on Camac serial loops and parallel branches handled by a minicomputer (specific language for programming) and local microprocessors (assembly language). In 1993, a major evolution replaced the Camac serial controllers by RTVAX/VaxELN CPUs linked through an Ethernet network integrating Vax/VMS machines. The Ada programming was used at every control system layer so all the software had to be rewritten while most of the hardware interfaces remained unchanged. In 1996, was introduced the VME standard with RTVAX/VaxELN CPUs then from 1998 by PowerPC/VxWorks CPUs, both still programmed in Ada. The last important evolution of the original Ganil installation control system was the migration from VMS servers to Linux ones in 2003. After two generations for the hardware servers organised as a cluster group, the last migration consisted this year of setting the servers into virtualized machines (Proxmox solution). When the Spiral2 project started, many reflexions were carried out for the solution to be considered for the control system to be provided, so provoking many and strong debates. Even if the Ganil control system was functioning pretty well in a robust way, it was decided in 2006 to base the future control system upon a solution widely used among many laboratories, so allowing sharing developments and solutions and being within an opened environment. Epics was therefore chosen to be the basic framework for the control system. Is was decided nevertheless that the future Spiral2 control system would share the same central servers as the original installation control one; the VME standard was kept both for having the same hardware solution and minimizing human resources for implementation. At the same time, the aim was to ease the 16th Int.

Animal infectious diseases interfere with the sustainability of livestock farming. Developing comprehensive strategies for disease prevention and control requires professionals to study livestock farms from a variety of data sources, such as veterinary medical tests, financial reports, and animal movements between farms. However, investigating animal health surveillance is challenging as the collected data is often heterogeneous, high-dimensional, and spatio-temporal. Furthermore, data missingness, one common challenge in disease surveillance, can limit the effectiveness of the analysis and induce the misinterpretation of the result due to the lack of uncertainty representation. In this paper, we present a visual analytics interface of coordinated views that supports investigating disease outbreaks by connecting the relationships of livestock farms from different aspects — geospatial, transactional, and financial. Coupled with unsupervised machine learning methods, we infer the health status of a farm, despite the absence of its diagnostic history, with uncertainty and provide interpretability to such inferences. With these functionalities, we further quantify the influence of a disease outbreak, severity and scale, guiding the user toward investigating important outbreaks. We demonstrate the analysis capability of our visual analytics interface with multiple use cases on a real-world swine production dataset.


Cancer is beginning to outpace cardiovascular disease as the primary cause of death in the world. The quality and lifespan of patients with malignancies has improved with the newer and advanced chemotherapeutic agents. These patients are often posted for various types of elective and emergency surgeries. The anaesthesiologist faces a challenging task, as these patients have gross physiological derangements due to radiotherapy, toxicity of chemotherapeutic agents and potential drug interactions. Thorough preoperative assessment, optimization of physiological milieu, vigilant intraoperative monitoring, anticipation of potential complications and postoperative pain control plays important role in reducing perioperative mortality and morbidity in these patients.


Objective To investigate the relationship of the expressions of cyclooxygenase-2(COX-2),P-glycoprotein(P-gp) and survivin with the chemosensitivities of gastric carcinoma with lymph node metastases(LNMs) in vitro.Methods The chemosenisitivities to 9 kinds of drugs were measured by MTT assay,and the expressions of COX-2,P-gp and survivin were determined immunohistochemically in 40 paired primary tumors(PT) and LNMs of gastric carcinoma.Results The accordance rate of COX-2 expression was 30% betwen PT and LNMs(P0.05).The expression of COX-2 was higher in LNMs than that in PT(P0.05).The expression of COX-2 in PT and LNMs was positively correlated with survivin(P0.01).There was a positive correlation between COX-2 and P-gp in LNMs(P0.05).The inhibition rate of LNMs cells for VCR,OPT or DDP was lower than that of PT(P0.05),which only for VP-16 was higher(P0.05).There was a statistically negative correlation between the expression of COX-2 and inhibition rate of PT for 5-FU or OPT(P0.05),and of LNMs for VP-16,OPT or eADM(P0.05).Conclusion COX-2 takes part in multiple drug resistance(MDR) of gastric carcinoma.The expression and chemosensitivitiy of COX-2 in LNMs of gastric carcinoma are different from those in PT.Effective adjuvant chemotherapy in gastrointestinal cancers should be focused on the metastatic components of the tumor.


An embedded cell model is presented to obtain the effective elastic moduli and the elastic-plastic stress-strain relations of three-dimensional two-phase particulate composites. Each cell consists of an ellipsoidal inclusion surrounded by a finite ellipsoidal matrix that embedded in an infinite matrix. When both matrix and particle are elastic, the effective elastic moduli are derived which is an exact analytic formula without any simplified approximation that can be expressed in an explicit form. Further, the elastic-plastic stress-strain relations are obtained for spherical cells and oblate spheroid cells, in which the matrix is elastic and the particle is elastic-plastic. In addition, the macroscopic elastic-plastic constitutive relation of particle reinforced composites (PRC) is investigated by a systematic approach [1] in which the matrix is elastic-plastic and the particle is elastic.


Physical and mechanical properties were determined for saligna eucalyptus ( Eucalyptus saligna, Smith) grown in Hawaii. In comparison with wood of the same species grown in Australia, saligna eucalyptus grown in Hawaii was lower in density, shrinkage, and compressive strength parallel to grain; it was about equal in strength in bending and shear; and it was stiffer. Compared to commercially important Mainland species, saligna eucalyptus grown in Hawaii is considered exceptionally stiff and the green wood is stronger than average for its density: however, strength of air-dry wood and hardness of green and air-dry wood are considered about average for the density. Prepared in cooperation with the Pacific Southwest Forest and Range Experiment Station, U. S. Forest Service, The Division of Forestry, Hawaii Department of Land and Natural Resources provided substantial financial support, some material, and also aided in logging and preparing the material. R. G. Skolmen, Research Forester at the Station's Forestry Research Center, Hawaii, selected the material and provided information on the trees and forests sampled. Hawaiian Fern-Wood Ltd. logged part of the material and helped prepare material for shipment. The Forest Products Laboratory is maintained at Madison, Wis., in cooperation with the University of Wisconsin. PHYSICAL AND MECHANICAL PROPERTIES OF SALIGNA EUCALYPTUS GROWN IN HAWAII 1


EDITOR,--C R Packham1 suggests that case mix may have been responsible for the variation among hospitals in 90 day mortality after admission for fractured hip that we reported.2 The possibility that patients' characteristics may explain differences in outcome is the reason why a multivariate analysis was necessary. Clearly, such an analysis has to be limited to those factors for which information is available, and our prospective audit, like any other study, could not record every conceivable potentially explanatory factor. This …


The isomers of [Co(NH3)2(tn)2]3+ were separated by recycling chromatography. The CD spectra of cis isomers were obtained and are compared with the spectra of the corresponding tris complexes. The magnitude of CD intensity of bisdiamine complex is roughly one-third of the corresponding trisdiamine complex.


No amount of time spent upon Christ's witty sayings can be superfluous, especially if previous attempts to 'unwind' or 'decode' them have proved inadequate. Many have tried to explain the saying about the Millstone,' and that about the Dead Burying the Dead. 2 Here both will be explained de novo. Admittedly what will not be explained will be the question whether Jesus understood the biblical texts (to which he alluded) to be predicting his own time not merely as the prelude to the Roman War and the Fall of Jerusalem, but also as the messianic age. The material given in this present article cannot settle that tremendous question. Jesus's handling of scripture is autonomous,' and he must not be squeezed into other people's shoes.
