Protonation increases the total binding energy of the 8-oxoguanine-cytosine (8OG:C) base pair by 60–70% at the B3LYP/6-311++G(d, p) level of theory. It changes the individual H-bond energies, estimated from electron charge densities at bond critical points, by 1.16 to −16.41 kcal mol−1. The individual H-bond energies and the two bond X–Y spin–spin coupling constants (2hJX–Y) increase with protonation where 8OG behaves as an H-bond donor; the reverse is true for the H-bonds in which the 8OG unit acts as an H-bond acceptor. Similar to 2hJX–Y, the value of 1hJO–H (a one-bond H ··· Y spin–spin coupling constant) is distance dependent and in linear correlation with the O ··· H distance, but the 1hJN–H values are independent of the N–H distance and the PSO term is the predominant portion in it. The 1JX–H spin–spin coupling constant is dominated by the negative FC term for all hydrogen bonds, although the PSO term is the best to investigate the behaviour of 1JX–H across the X–H · Y H-bond.


GaAs layers grown by close-spaced vapor transport on (100) Ge substrates have been investigated as a function of the experimental growth conditions. The effects on the microstructure of the surface preparation, substrate misorientation, and annealing were studied using optical microscopy and transmission electron microscopy. Microtwins and threading dislocations are suppressed by oxide desorption before deposition. Single domain GaAs layers have been obtained using a 50 nm thick double domain buffer layer on an annealed Ge substrate misoriented 3°toward [011]. The mismatch strain is mainly accommodated by dissociated 60°dislocations. These misfit dislocations extend along the interface by the glide of the threading dislocations inherited from the substrate, but strong interaction with antiphase boundaries (APB's) prevents them from reaching the interface. These results are discussed and compared with previous reports of GaAs growth on Ge(100).


Kefir is a functional drink that contains probiotic microbes to nourish digestion. There are 2 types of kefir namely milk kefir and water kefir. Kefir water has advantages, like: slightly sour taste, low alcohol and low fat content. One of the fruits that can be used as a source of nutrition for water kefir fermentation is soursop fruit which is rich in fiber, vitamin C, and antioxidants. The purpose of this study was to determine whether there was interaction and the influence between differences in sucrose concentration and starter concentration on the quality of water kefir soursop.
The research method used is: Randomized Block Design (RBD) with 2 factors. The first factor is the difference in sucrose concentration, which is 2%, 4%, 6% and 8%. The second factor is the difference in starter concentration, which is 4% and 8%. The observed parameters were chemical quality (total acid titration, pH, reducing sugar, and alcohol content), physical quality (color intensity (L, a, b)), microbiological quality (total lactic acid bacteria (LAB), and total yeast ), as well as organoleptic parameters (aroma, taste, mouthfeel, preference).
The results of the study revealed that there was an interaction between the treatment of differences in sucrose concentration and starter concentration on titrated total acid, pH, reducing sugar, alcohol content, total LAB, total yeast, color intensity (L, a, b), and organoleptic (aroma, flavor , mouthfeel, favorite) on soursop water kefir. The best treatment was B2S2 (4% sucrose and 8% starter) which had TAT 1.24%, pH 3.60, alcohol content 1.68%, reducing sugar 2.22%, color (L = 57.30; a + = 1.4; b + = 6.3), total BAL 2.06 x 108 (CFU / ml), total yeast 1.7 x 105 (CFU / ml), aroma 4.32, taste 4.25 (acid), mouthfeel 3,50, and preferably3,55


Nanowires (NWs) have many enhanced properties such as high yield strength, high ductility and large elongation under tensile loading. Though many molecular dynamics simulations have been performed exhibiting the benefit of having grain boundaries in nanowires, this study focuses on the mechanical properties of a specific grain formation similar to a structure of bamboo that indicates the opposite phenomena. In this experiment, BCC Fe nanowires were strained under tensile loading and with the assistance of molecular dynamics simulation it was demonstrated that the behavior of polycrystalline Fe NW exhibits dramatic differences from their single crystalline NW counterparts. In single crystalline Fe NW, dislocations were generated from the surface in the directions of specific planes for BCC materials; whereas in the case of nanowire with bamboolike polycrystalline shape, dislocation were generated from grain boundary due to the localized high stress and the heterogeneous character of atoms in the grain boundary. Ultimate strengths for 〈111〉, 〈1-1-2〉, 〈102〉 and 〈110〉 oriented single crystal NWs were found 34.57 GPa, 19.15 GPa, 14.94 GPa and 25.48 GPa respectively. A substantial low strength (8.89 GPa) was observed for the polycrystalline Fe structure, which was mainly caused due to the deformation in the interface of the two subsequent grains. Necking was observed followed by fracture, resulting in an overall drop in toughness. These findings can be a matter of concern in certain applications where materials with high strength and stability are required.


Introduction: Radiofrequency catheter ablation (RFCA) for asymptomatic atrial fibrillation (AF) is not indicated due to limited data on it's clinical efficacy. This study evaluated the change in oxygen kinetics and cardiopulmonary performance parameters after RFCA for asymptomatic (Canadian Cardiovascular Society-Severity of AF scores = 0) Chronic AF patients. Methods: A total of 57 patients with asymptomatic chronic AF (age 60 ± 9 year-old, 89.5% male, AF duration 51 ± 49 months) divided into 2 groups according to sinus rhythm conversion via RFCA: Group 1 (Rate control, n=32); Group 2 (Rhythm control, n=25). The patients who achieved sinus rhythm by antiarrhythmics (n=20) and cardioversion (n=4) were excluded. All underwent two times of treadmill cardiopulmonary exercise tests (modified Bruce protocol, Quark CPET®, COSMED, Italy) before and after each treatment (follow-up periods, 250 ± 181 days). Peak oxygen uptake (Peak VO2, ml/min/Kg) as aerobic capacity, O2-pulse at peak (ml/beat) for cardiovascular ...


We study how barter exchanges should be conducted through a centralized mechanism in a dynamically evolving agent pool with time- and compatibility-based preferences. We derive the dynamically efficient two-way and multi-way exchange mechanisms that maximize total discounted exchange surplus. Recently several live-donor kidney exchange programs were established to swap incompatible donors of end-stage kidney disease patients. Since kidney exchange can be modeled as a special instance of our more general model, dynamically efficient kidney exchange mechanisms are derived as corollaries. We make policy recommendations using simulations.


Abstract : This paper discusses a particular type of function approximation on scattered data in a general number of variables, and its application to surface representation with imposed conditions. If the given function values are subject to errors, it is not appropriate to interpolate the function at the data in the sense of exact matching. As a consequence, we formulate a weakened version of the classical scattered data interpolation problem, and give a simple and efficient procedure to obtain near-interpolation formulas. Near-interpolants enjoy many remarkable properties, which are very useful from both theoretical and practical points of view (shape preserving properties, operator positivity, subdivision techniques, parallel and multistage computation). Applications of near-interpolants to the representation of surfaces, in particular with faults, are discussed in detail (parameter values, localizing weights, etc.).


CagL is an essential pilus surface component of the virulence‐associated type IV secretion system (T4SS) employed by Helicobacter pylori to translocate the oncogenic effector protein CagA into human gastric epithelial cells. CagL contains an RGD motif and integrin α5β1 is widely accepted as its host cell receptor. Here, we show that CagL binds integrin αVβ6 with substantially higher affinity and that this interaction is functionally important. Cell surface expression of αVβ6 on various cell lines correlated perfectly with cell adhesion to immobilized CagL and with binding of soluble CagL to cells. We found no such correlation for α5β1. The purified αVβ6 ectodomain bound CagL with high affinity. This interaction was highly specific, as the affinity of CagL for other RGD‐binding integrins was two to three orders of magnitude weaker. Mutation of either conserved leucine in the CagL RGDLXXL motif, a motif that generally confers specificity for integrin αVβ6 and αVβ8, lowered the affinity of CagL for αVβ6. Stable expression of αVβ6 in αVβ6‐negative but α5β1‐expressing human cells promoted two hallmarks of the functional H. pylori T4SS, namely translocation of CagA into host cells and induction of interleukin‐8 secretion by host cells. These findings suggest that integrin αVβ6, although not essential for T4SS function, represents an important host cell receptor for CagL.


As much as animalia and vegetation exhibit autonomous natures comparable to that of humans, they do not evidence any intrinsic dependence on humans to exist. In their specific universal natures, they appear to stand in relationship above all to climate, just as humans ultimately do. They in fact share with man the basic conditions of life within the unity of all beingness. And so I revise the Pythagorean maxim and declare "Life is the measure of all things." It is life that maintains the unity of all beingness. Anna-Teresa Tymieniecka, "The Pragmatic Text of the Ontopoeisis of Life." In explaining the methodology and field of study that constitute "pure phenomenology," Edmund Husserl describes a "science of consciousness" that is wholly distinct from the objective sciences. Likening phenomenology to the pure mathematical sciences because it seeks to comprehend "essential laws" that govern consciousness, just as mathematical laws govern spatial reality, Husserl prescribes phenomenological methods – intuition and reflection – that are introspective rather than empirical. While objective sciences look outward to the transcendent realm of Nature as their given field of study, phenomenology turns inward to contemplate the cogito, the conscious subject in the act of knowing. With an exclusive focus on the structures and operations of consciousness as an active force in and of itself, pure phenomenology assumes the radical separability of Mind and Nature, and for the individual phenomenological subject this means accepting, as well, the radical separability of mind and body. To apprehend pure consciousness undistorted by received knowledge and preconceptions about the self and the world, Husserl calls for "phenomenological reduction," excluding from consideration all beliefs derived from objective experience. Through this radical suspension of empirical belief, the phenomenological field is cleared of all but consciousness 33


Purpose - After discussing the high and rising health care costs in the USA, its disparities, and the suggested demand, supply, and managed competition-side strategies to contain health care costs and their ethical implications, this paper seeks to explore whether or not these strategies will further aggravate the existing health care disparities. Design/methodology/approach - This conceptual paper utilizes various appropriate exiting economic and ethical theories. The economic and ethical theories utilized are relevant to the problem of rising health care costs; to the proposed demand, supply, and managed competition-side cost containment strategies; and to the existing health care disparities. Findings - This paper demonstrates that the suggested cost containment strategies do in fact aggravate existing health care inequities and are not always ethical. Originality/value - Given the present health care reform debate in the USA and various misconceptions about it, the author believes that the paper and its findings should in fact be viewed as a contribution.


BACKGROUND
Patients with advanced lower limb ischaemia are, at present, mainly treated using revascularisation.

AIM
The aim of the study was to investigate whether the dynamics of blood flow in below-the-knee (BTK) arteries assessed by angiography correlate with clinical outcomes after a 12-month follow-up in patients with severe leg ischaemia treated per-cutaneously.

METHODS
The current study enrolled 287 consecutive patients who underwent 302 endovascular procedures on the infrain-guinal arteries. The mean age of the included participants was 67.4 ± 10.4 years. After the procedure, blood flow in all patent BTK arteries was assessed using frame count (FC). Patients were then evaluated after one, three, six, and 12 months. During the follow-up visits, clinical condition was evaluated based on the Rutherford scale, ankle-brachial index, and the need for reintervention or amputation.

RESULTS
Clinical improvement at the end of the follow-up period was observed in 242 (80.1%) cases and no improvement or worsening in was seen in 42 (13.0%) patients. In total, 66 (21.8%) reinterventions and 18 (6%) amputations during the follow-up period were recorded. Patients with higher FC in the tibial anterior artery experienced significantly better clinical improvement within the 12-month follow-up period (p = 0.02). Lower FC predisposed to worse clinical outcomes after an-gioplasty. Similar tendencies were found for the tibial posterior and fibular arteries but without statistical significance.

CONCLUSIONS
The results suggest a negative relationship between FC observed on the final angiogram and clinical outcomes in patients undergoing endovascular treatment of the peripheral arteries.


Godert notes that, having survived a period where we were drowning in information, we seem to be in a period where we are happily surfing the Internet. This communication considers the social implications of this change in fundamental metaphors about our relationship to information. It is first proposed that, though a paradigm shift has not occurred, the significance of the change should not be minimized. The similarities and differences between surfing and drowning are then considered. Questions suggested by these similarities and differences are offered for consideration.


Variations in 1-g and 10-g specific absorption rate (SAR) values due to variation in tissue dielectric properties are determined. To accomplish this goal, stochastic finite difference time domain (S-FDTD) and Monte Carlo methods are compared. A 3D head model with variable dielectric properties is exposed to a half wave dipole antenna at 835 and 1900 MHz. The results show that these variations can significantly affect the peak 1-g and 10-g SAR values and should be considered in SAR guidelines for cell phone assessment.


Since YU Hua presented his literary creation as pioneers in 1980s, the readers has always looked forward to his works. However, it seems that he has stepped into the "deep valley" of his literary creation since he finished his three novels in the mid 1990s. His works has been out sight of the market for six or seven years, which resulted from his own reasons as well as the influence of marginal atmosphere of literature.


In the current paper, an efficient in situ solvent formation microextraction (ISFME) combining high performance liquid chromatography with fluorescence detection was developed for the determination of sanguinarine and chelerythrine in Macleaya cordata (Willd.) R. Br. and Chelidonium majus L. The amount of ion-pairing agent (KPF6) was added to the sample solution containing a water-miscible ionic liquid (IL; [C6MIM][Br]) to obtain a hydrophobic ionic liquid ([C6MIM]PF6), which acted as the extraction phase to replace the volatile organic solvent as the extraction solvent. Several important parameters influencing the extraction efficiency of IL-ISFME, such as the type and volume of IL, amount of KPF6, sample pH, extraction time, and centrifugation time, were optimized. Under optimal conditions, sanguinarine and chelerythrine exhibited good linearity, with correlation coefficients of 0.9992 and 0.9993, respectively, linear range of 0.1–200 ng mL−1, and limit of detection of 0.08 ng mL−1. The spiked recovery for each analyte was in the range of 97.8%–102.3%. The experimental results indicate that the proposed method was successfully applied to the analysis of two alkaloids in M. cordata (Willd.) R. Br., C. majus L. and human urine.


In recent years, cases of unexplained, elevated levels of radioactive particles have demonstrated an increasing need for efficient and robust source localization methods. In this study, a Bayesian method for source localization is developed and applied to two cases. First, the method is validated against the European tracer experiment (ETEX) and then applied to the still unaccounted for release of Ru-106 in the fall of 2017. The ETEX dataset, however, differs significantly from the Ru-106 dataset with regard to time resolution and the distance from the release site to the nearest measurements. Therefore, sensitivity analyses are conducted in order to test the method's sensitivity to these parameters. The analyses show that the resulting source localization depends on both the observed temporal resolution and the existence of sampling stations close to the source. However, the method is robust, in the sense that reducing the amount of information in the dataset merely reduces the accuracy, and hence, none of the results are contradictory. When applied to the Ru-106 case, the results indicate that the Southern Ural region is the most plausible release area, and, as hypothesized by other studies, that the Mayak nuclear facility is the most likely release location.

Software product lines are dynamic systems that need to evolve continuously to meet new customer requirements. This evolution impacts both the core platform of the product line and its derived products. For several reasons, the most common way to express requirements by customers is natural language. However, the experience has shown that this communication channel does not give the possibility to detect system defects such as inconsistency and duplication. The objective of this paper is to propose a method to transform textual requirements into the XML format used by some Feature-oriented software development tools, in order to facilitate the detection of features duplication.


Summary We studied human platelet aggregation and β-TG/PF4 release induced by heparin and related GAGs in vitro both in normal PRP and in PRP after aspirin. In our experimental conditions, heparin and related GAGs always caused PF4 release in vitro from normal platelets, whether or not there was measurable platelet aggregation in the aggregometer. Significant β-TG release was induced only by the mucosal heparin preparation (which also induced platelet aggregation in some citrated PRP). Therefore, while β-TG release in vitro seems to correlate with platelet aggregating activity of heparin, the selective PF4 release, caused by heparin and related GAGs also in conditions in which neither platelet aggregation nor β-TG are measurable, is probably associated with the high affinity of PF4 for heparin. The degree of affinity of GAGs for PF4 (heparin > DeS > HS) seems to correlate with PF4 release. Moreover, the significant reduction in PF4 release in vitro after aspirin suggests that GAGs-induced PF4 release is related to a cyclooxygenase-dependent activation process.


Haramati et al. have described a "rapid" method of skin grafting in mice in your November 2007 issue (1). They were encouraged to do so because the very simple method described by Billingham and Medawar (2) in the early 1950s led to an alarming mortality rate approaching 20% in their hands. This is of course quite unacceptable, but is it inevitable? The Medawar group used this method, involving a nonstick dressing and small plaster cast, for decades, as have countless others, without any significant mortality. There clearly was something radically wrong with the way these authors used the technique, and thus they were led to reinvent the wheel. The new method is carried out without any bandaging but, though the mortality was largely eliminated, a small number of mice lost their grafts, something that should never happen with bandaged mice. What is more, the unbandaged mice had to be caged individually until at least the sixth day. This would seem to be a significant disadvantage in any laboratory that deals with reasonably large number of experimental animals. The authors describe how to obtain skin grafts from donor tails. Although this may not have been detailed by Billingham and Medawar in their 1951 article, this method was soon adopted by the Medawar group and was used and described in many of their studies. Tail skin is easier to prepare: there is no need to remove the panniculus carnosus because there isn't one. The bandage over the dorsolaterally placed graft on the thoracic wall provides not only protection but slight pressure to facilitate graft vascularization. Donor tail skin hair growth on long-term accepted grafts is easily distinguishable from that of body skin hair of the hosts. Rather than try to master the new technique, which seems to have some pitfalls of its own, experimental surgeons might well prefer to stick with the old and well-tried method!

The use of spare tiles in a networks-on-chip based multi-processor chip can improve the yield, reducing the cost of the chip and maintaining the system functionality even if the chip is defective. However, the impact of this approach on application characteristics, such as energy consumption and execution time, is not documented. For instance, on one hand the application tasks might be mapped onto any tile of a defect-free chip. On the other hand, a chip with a defective tile needs special task mapping that avoid fault tiles. This paper presents a task mapping aware of faulty tiles, where an alternative task mapping can be generated and evaluated in terms of energy consumption and execution time. The results show that faults on tiles have, on average, a small effect on energy consumption but no significant effect on execution time. It demonstrates that spare tiles can improve yield with a small impact on the application requirements.


The quantity of RA(register agency) supported by DOI is definite and limited.The process and present stage of DOI protocol in ISO and the fee standard of RA are introduced.The dual-charge and expensive fee are the main obstacle for DOI promotion.The classification of the publishing organizations at home and abroad and the investigation to purchased databases product of users find that an individual journal database is unwelcome and the union is more effective and necessary.If the non-core metadata extend to include price and other business items,DOI may become a new journal business platform supporting journal publishers to make their own prices.


Robotnačka is an autonomous drawing mobile robot, used for teaching beginners in the Logo programming language. It can be used also as an experimental platform, in our case in a remotely accessible robotic laboratory with the possibility to control the robots over the Internet. The laboratory can be settled up to three robots. In addition to the basic version of the robot we have also a version equipped with the gripper, one with the wireless camera, and one with an extension with ultrasonic distance sensors. The laboratory is available on-line for 24 hours 7 days a week and provides a simple way to incorporate robotics in teaching of mathematics, programming and other lectures. The laboratory has been in use for several years. We provide description of its functionality and summarize our experiences.

How does the cost burden of housing impact health? Housing is an important social determinant of health, and the cost burden of housing impacts health both directly and indirectly. Unaffordable housing costs can cause financial strain, limiting the amount of money that can be spent on medication, healthcare, healthy food, and heating fuel. This can impact a range of health outcomes, and one study found that people living in unaffordable housing were more likely to experience poor self-rated health, hypertension, cardiovascular disease, asthma, and obesity (Pollack, 2010, Am J Prev Med). These households also had increased healthcare costs, prescription nonadherence, emergency department visits, and lack of insurance.


Although many policy process and diffusion theories follow the premise that scientific and technological knowledge plays a crucial role in a wide variety of policy fields, very few empirically assess the impact that institutional and process-relevant factors may have on the position of science within a process. The present study addresses the question of what role science plays in policy processes. To answer this, we apply the Advocacy Coalition Framework (ACF) and investigate three complementary assumptions using a qualitative comparison of four cases: the ACF claims that scientific experts can take very different positions in the policy process, depending on how conflictive or consensus-oriented the relations among actors and coalitions are within a so-called policy subsystem. Put differently, the type of subsystem impacts on the position of science within the process. The results show that subsystem-specific factors impact upon whether scientific representatives act at the periphery of a process or as policy brokers seeking feasible policy solutions.


Language change is the premise of literary development. Triggered and beckoned by the new era's writing and "language's self consciousness", the writers obtained a lot in exploring the latent expressive function of the modern vernacular literature and enriching the expressive power of the literary language by transplanting the living part of the classic literary language and the oral. Thus, the self reliance function of literary language, diversity of linguistic methods and writing styles are easy to recognize.


Based on the multiple fork tree of light transmission,the stray light and ghosts caused by multi-order diffraction and multi-reflection in the terminal optical system of high power laser setup used in inertia confined fusion(ICF) were discussed.Real ghost rays were traced according to the ray transmission law through a color separation grating.And over-round analysis for the stray light and the focusing ghost images in the system,which consists of a focusing lens,a color separation grating,and baffle shields,was completed.It was observed that there were 620 third harmonic ghosts and relative less second harmonic and fundamental frequency ghosts.It can be concluded that the ghost formed by the first reflection of aspheric surface is most harmful.With the diffraction of large angles and the reflection of tilt planes,a lot of ghosts are moved outside the system and their aberrations are increased so that their harmfulness is weakened.All of the ghosts can be caught in the form of dynamic data structure and the ghost beam structure can be obtained.


The research aimed to obtain phosphate porcelain, by using the ash resulting from burning bones from meat processing plants. The applied processing technology allows obtaining fine ceramics at lower temperatures than the one used in the case of feldspar porcelain, having as effect the increase of the durability of the firing furnaces and the realization of the products at lower production costs. Five series of phosphate porcelain samples were performed in laboratory conditions, with different compositions, by firing at a temperature of 1250 ℃, temperatures lower than those necessary for the firing of feldspar porcelain of 1350-1450 ℃. The porosity and density of the samples were determined and the microstructural analysis of the materials made in the five research variants was made.


We investigate optimal conditions for the quantum interface between a signal photon pulse and one-dimensional chain consisting of a varied number of atoms. The tested object is physically designed as an atomic array of tripod-type atoms confined with a nanoscale dielectric waveguide and experiencing its fundamental HE11 mode. The efficiency of interaction is mainly limited by achieved overlap and coupling of the waveguide evanescent field with the trapped atoms. We verify those physical conditions when the coupling within the main scattering channels would be sufficient for further providing various elementary interface protocols such as light storage, light-matter entanglement, preparation of a few photon states on demand, etc.


The purpose of this paper is to evaluate the energy conservation potential of an underfloor air distribution (UFAD) system integrated with an indirect and direct evaporative cooling assisted 100% outdoor air system (IDECOAS) in hot and humid climate. It is assumed that an office space is served by five different HVAC systems. Energy simulation for each system was performed using a commercial equation solver program, and the operating energy consumption in each system is compared. The results show that the UFAD system integrated with IDEC OAS reduces the cooling coil load by 47~63%, heating coil load by 89~94% and the total annual operating energy consumption by 47% with respect to the conventional overhead and the UFAD systems.


Despite the significant advances in convolutional neural network (CNN) based image denoising, the existing methods still cannot consistently outperform non-local self-similarity (NSS) based methods, especially on images with many repetitive structures. Although several studies have been given to incorporate NSS priors with CNN-based denoising,their improvement is generally insignificant when compared with the state-of-the-art CNN-based denoisers. In this paper, we suggest to combine CNN and NSS based methods for improved image denoising, resulting in an NSS-UNet architecture. Motivated by gradient descent inference of TNRD, both the current estimate and noisy observation are considered as the inputs to the CNN. To take the NSS prior into account, the result by NSS (e.g., BM3D or WNNM), is adopted as the initial estimate. And a modified UNet is presented for exploiting the multi-scale information. We evaluate the proposed method on three common testing datasets. The results clearly show that NSS-UNet outperforms the existing CNN and NSS based methods in terms of both PSNR index and visual quality.


Abstract A map is frequently combined with a text to provide spatial and non-spatial information for learners. How a map and a text are combined and the characteristics of learners are keys for understanding successful learning. This study used a cognitive experiment to investigate spatial learning by explaining performance on a test of acquired knowledge with variables related to the learning environment and to individual differences of learners. Results indicate that having participants read a text beside a map produced the best performance. Participants were more successful at learning the information in the text and less successful at learning the information on the map. Performance was measured by accuracy, reaction time, and confidence measures; a standardized index for overall efficiency combined these measures. Performance was significantly related to individual difference variables measuring experience, verbal and spatial working memory capacity, 2D/4D digit ratio, and cognitive style. Sex and ge...


Architects, transit planners, engineers, and others who design transit facilities and transportation vehicles need to be aware of the range of abilities and disabilities present in persons who ride transit. Consideration of the human performance capabilities and the unique needs of riders who do not conform to 'average' specifications can lead to the planning of vehicles and facilities which are accessible to a much greater number of potential users. This document presents information pertinent to a general understanding of visual impairment and the visually impaired, as well as specific information on the characteristics of accommodations which are typically made for this population. The document presents a collection of reports prepared as part of a project which studied communication with the visually impaired in rail rapid transit systems. The reports contained within this document should be of help to architects and transit planners who are attempting to design environments which are free of barriers to the visually handicapped.


Gan et al., 2020 reported that about 40% of hospitalized elderly with COVID 19 presented with atypical symptoms including falls, reduced mobility, weakness and confusion as a main complaint in the community. Fever and cough were the most frequent symptoms in elderly patients on admission in the multicenter, retrospective study by Guo and his colleagues, however they were less prevalent in elderly when compared to other age groups. A prediction model was developed to predict COVID 19 course and outcome based on time series of clinical symptoms. It reported 6 clusters of symptoms. Cluster 1 and 2 were milder forms of COVID-19 with minimal need for respiratory support. They mainly present with upper respiratory tract symptoms and were distinguished by the absence of muscle pain in Cluster 2 compared to Cluster 1, and slightly increased reports of skipped meals and fever in Cluster 2.

Classical trajectory calculations for collisions between vibrationally hot pyrazine (E = 40332 cm-1) and room-temperature CO are compared with recent diode laser experiments. Ab initio calculations were carried out to determine parameters for the pairwise Lennard-Jones intermolecular potential. The trajectory results appear to show good qualitative agreement with preliminary experimental results. The highest ΔE collisions occur when the CO happens to lie above the pyrazine plane just as the underlying CH wag executes an unusually high amplitude motion. Artificially doubling the length of the CO produces results for the angular momentum transfer to the CO molecule that look quite similar to those for angular momentum transfer to CO2 in analogous pyrazine−CO2 experiments.


This paper describes the disadvantages of spreadsheet-based analysis for high-speed multimode systems and presents multimode system simulation as an alternative. An example is depicted in which the system power margin calculated by the spreadsheet model was overly pessimistic relative to that predicted by system simulation. The higher degree of accuracy and flexibility afforded by multimode system simulation should enable component tolerances to be relaxed, resulting in an overall reduction in system cost.


Prasugrel and ticagrelor are both effective anti-platelet drugs for patients with acute coronary syndrome. However, there has been limited data on the direct comparison of prasugrel and ticagrelor until the recent ISAR-REACT 5 trial.

 To compare the efficacy of prasugrel and ticagrelor in patients with acute coronary syndrome with respect to the primary composite endpoint of myocardial infarction (MI), stroke or cardiac cardiovascular death, and secondary endpoints including MI, stroke, cardiovascular death, major bleeding (Bleeding Academic Research Consortium (BARC) type 2 or above), and stent thrombosis within 1 year.

 Meta-analysis was performed on randomised controlled trials (RCT) up to December 2019 that randomised patients with acute coronary syndrome to either prasugrel or ticagrelor. RCTs were identified from Medline, Embase and ClinicalTrials.gov using Cochrane library CENTRAL by 2 independent reviewers with "prasugrel" and "ticagrelor" as search terms. Effect estimates with confidence intervals were generated using the random effects model by extracting outcome data from the RCTs to compare the primary and secondary clinical outcomes. Cochrane risk-of-bias tool for randomised trials (Ver 2.0) was used for assessment of all eligible RCTs.

 411 reports were screened, and we identified 11 eligible RCTs with 6098 patients randomised to prasugrel (n=3050) or ticagrelor (n=3048). The included trials had a follow up period ranging from 1 day to 1 year. 330 events on the prasugrel arm and 408 events on the ticagrelor arm were recorded. There were some concerns over the integrity of allocation concealment over 7 trials otherwise risk of other bias was minimal. Patients had a mean age of 61±4 (76% male; 50% with ST elevation MI; 35% with non-ST elevation MI; 15% with unstable angina; 25% with diabetes mellitus; 64% with hypertension; 51% with hyperlipidaemia; 42% smokers). There was no significant difference in risk between the prasugrel group and the ticagrelor group on the primary composite endpoint (Figure 1) (Risk Ratio (RR)=1.17; 95% CI=0.97–1.41; p=0.10, I2=0%). There was no significant difference between the use of prasugrel and ticagrelor with respect to MI (RR=1.24; 95% CI=0.81–1.90; p=0.31); stroke (RR=1.05; 95% CI=0.66–1.67; p=0.84); cardiovascular death (RR=1.01; 95% CI=0.75–1.36; p=0.95); BARC type 2 or above bleeding (RR=1.17; 95% CI =0.90–1.54; p=0.24); stent thrombosis (RR=1.58; 95% CI =0.90–2.76; p=0.11).

 Compared with ticagrelor, prasugrel did not reduce the primary composite endpoint of MI, stroke and cardiovascular death within 1 year. There was also no significant difference in the risk of MI, stroke, cardiovascular death, major bleeding and stent thrombosis respectively.

Abstract This paper presents a unified approach to the distributions of the product of k (≥2) maximum values, and the product of k sample ranges from rectangular populations, both for equal and unequal sample sizes. The results obtained are generalisations based on some earlier work of Rider. It is proved that in all cases the distributions can be conveniently transformed to χ2's by the use of a well-known logarithmic transformation. It is also suggested that these results might be of use in quality control procedures in high precision production engineering with close specification limits.

Water jets and abrasive water-jet technology are the focus of concentrated research. This research area is oriented to understand the material-removal mechanisms and to optimise the process parameters fluid dynamical and technological) of various applications. The optimisation of the process parameters is especially difficult because of their instability during the process. Many authors have inquired into the physical-mechanical aspects of the interaction between the jet and the mechanical properties of the material and they have developed models and different interpretations. However, the existing models, mostly try to describe the cutting mechanism only for abrasive water-jet (AWJ) technology. The interpretation of the mechanism of striation formation in AWJ cutting does not explain the striation formation in the pure WJ process. In fact, whereas in the cutting surface realised by a pure WJ cutting along the whole surface there are irregularities (striations); the surface generated by A WJ cutting is characterized by a streaked morphology in the bottom zone of the cutting surface. Previous studies have demonstrated that the cutting surface realised by WJ is not influenced either by the pressure fluctuations or the pressure signal form, but depends strongly on the exogenous and endogenous vibrations. In fact, a considerable reduction of these vibrations makes it possible to obtain remarkable improvements in the surface quality, especially as regards the striation morphology. Although the pressure fluctuation does not have substantial effects on the WJ surface quality, it should have an influence on the depth of cut. In this work the effect of the pressure fluctuation on the depth of cut in no-passing WJ cuts has been analysed. In order to do this, the thrust trend of the water jet on a plane surface has been analyzed. The aim of this experiment has been to analyze the penetration ability trend of the jet at the exit of a passing cut; afterwards, the correlation between the thrust signal and the bottom profile generated by a no-passing cut on polycarbonate slabs has been analyzed.

Both ends of the frame are respectively provided with pitch axes arranged along a first direction, so that the frame can rotate around the pitch axes; on end of one pitch axis is fixedly connected with the frame and the other end of the pitch axis is in power connection with a pitch servo motor; a rotating shaft and a rotating servo motor are arranged in the frame; the rotating shaft is arranged in the frame along the direction vertical to the first direction in a penetrating mode and is in power connection with the rotating servo motor; and one end of the rotating shaft extends out of the frame and is provided with a rotating platform. The numerical control double-shaft rotary table is fixed on a numerical control machine tool and both the pitch servo motor and the rotating servo motor are connected to the numerical control machine tool, so that installation is completed. At the moment, due to an original three-axis linear freedom degree of the numerical control machine tool and rotating freedom degrees in X-axis and Z-axis directions, which are newly increased in the invention, rotary feed and dividing movement can be realized in random direction.


Objective: To investigate the developmental pathway of school failure from age 8 to age 11 by gender when the main effects and interactions of family adversity and the level of kindergarten disruptive behaviour were accounted for. Method: A population sample of boys (n = 862) and girls (n = 985) were followed from kindergarten up to age 11. Family adversity and disruptive behaviour were measured in kindergarten and school failure was assessed from ages 8 to 11. Results: A logit-linear analysis on the patterns of school failure revealed that there was no significant difference in the proportion of boys and girls transferred from an age-appropriate regular class by the end of elementary school. However, the age at which this transfer occurred differed by gender: Girls were found to experience failure later than boys do. The results also indicated that both family adversity and kindergarten disruptive behaviour had an effect on the proportion and age at which children were transferred from an age-appropriate regular class. Conclusion: Findings underline that the academic performance and delinquency relationship may be developmentally different by gender. Further research focused on understanding the impact of school failure by gender is needed to clarify these issues.


The effects of powder preparation and conditions of hot pressing on the structure and density of consolidated Sm2Fe17Nx and Sm2Fe17Nx∕Fe–Co magnets have been studied. Densities achieved in the case of Sm2Fe17Nx powders prepared through a low-energy milling were higher than after a high-energy milling. The difference is mostly caused by the different particle size, and it can be eliminated by an additional low-energy milling of the coarse high-energy milled powder. The presence of a ductile soft magnetic phase greatly facilitates densification, leading to considerably higher absolute and relative densities in hot-pressed Sm2Fe17Nx∕Fe0.65Co0.35 composites. We have found that during hot pressing, nitrogenization of the Sm2Fe17 phase may occur in situ if pressed together with Fe–Co–N powders. Because Fe–Co–N releases nitrogen below the decomposition temperature of Sm2Fe17Nx, we were able to fabricate the Sm2Fe17Nx∕Fe0.65Co0.35 composite with the density up to 7.6g∕cm3 by hot-pressing mixtures of Sm2Fe17 and (...


The International Law of Human Rights has expanded its content in an uninterrupted way in the last decades; Specifically on migration we have witnessed a wide development of conferences, agreements, forums, declarations, jurisprudence and doctrine. Thus, international bodies whose mandate revolves around international migration have recognized that current migratory flows have deep roots in history, politics and economics, so that it is not possible to foresee in the near future its decrease, cessation or deviation. Thus, countries strongly involved in the phenomenon must be aware of this reality and choose how to deal with the phenomenon legally.


In this paper, two approaches for the reduction of the dispersion of IDA curves are studied. In the first approach, equivalent single degree of freedom elasto-plastic systems producing maximum demands equal to the corresponding multi storey frames' demands are used in order to determine the effective period. In the second approach, Fourier amplitude spectra of the responses of the multi storey frames are drawn in order to determine the dominant frequency values for the earthquake scale factor corresponding to a particular value of the chosen damage measure. Although the latter reduces the dispersion considerably, the use of obtained frequency for the earthquake hazard definition is a subject which should be further studied. For the analyses two 10 story model frames are used; one is a special moment resisting steel frame and the other is a special reinforced concrete moment frame. PERFORM-3D and DRAIN-2DX structural analysis softwares are used for inelastic dynamic analyses of the R/C and steel model frames, respectively. The spectral calculations are carried out with the coded MATLAB scripts. The comparisons of the results are presented and comments are provided for future work.


The positions of sensor nodes in a Wireless Sensor Network (WSN) must be able to provide maximum coverage with a longer lifetime. This paper proposed a sensor node placement technique that utilizes a new biologically inspired optimization technique that imitates the behavior of territorial predators in marking their territories with their odors known as Territorial Predator Scent Marking Algorithm (TPSMA). The TPSMA deployed in this paper uses the maximum coverage ratio as the objective function. The performance of the proposed technique is then compared with other schemes in terms of uniformity and average energy consumption. Simulation results show that the WSN deployed with the proposed sensor node placement scheme consumes lower energy compared to the other two schemes and is expected to provide longer lifetime.


The law of transfer and conversion of pollutant,which come from the primary pollutant source including Zhihu port,Wujing port and Liangxi river in Meiliang Bay,was simulated using the mathematical model of water flow and water quality of Taihu lake.The incidence proportion between the four monitoring points' concentration and discharge capacity of those pollutant source was analyzed,and the response relation curve and response relation expression were also established in this paper.By using these conclusion,the variation of the monitoring points' concentration can be calcueculated conveniently,which can provide technical support for controlling the extraneous sources pollutant quantity inflowing to Taihu lake.


We derive a second-order linear differential equation for the leading-order gluon distribution function G(x,Q{sup 2})=xg(x,Q{sup 2}) which determines G(x,Q{sup 2}) directly from the proton structure function F{sub 2}{sup p}(x,Q{sup 2}). This equation is derived from the leading-order evolution equation for F{sub 2}{sup p}(x,Q{sup 2}), and does not require knowledge of either the individual quark distributions or the gluon evolution equation. Given an analytic expression that successfully reproduces the known experimental data for F{sub 2}{sup p}(x,Q{sup 2}) in a domain x{sub min}(Q{sup 2}){ or approx. 10{sup -3} as they should, but are much larger for x < or approx. 10{sup -3}.


The lining of an odontogenic cyst may show potential for neoplastic transformation to non odontogenic malignancies like squamous cell carcinoma and mucoepidermoid carcinoma and also odontogenic tumors like ameloblastoma and adenoamatoid odontogenic tumor (AOT). Unicystic ameloblastoma is a single cystic cavity lesion which shows ameloblastomatous differentiation in the lining. The clinical and radiological presentation of UCA can present a confusing picture of an odontogenic cyst, especially when it is seen in the inter-radicular or periapical area. Also, tooth associated UA may show features similar to dentigerous cyst. Hence histopathological examination is essential to diagnose such cases. Here, we present, a case of unicystic ameloblastoma arising from a dentigerous cyst associated with an impacted mandibular third molar. A literature review on the topic has also been added.

The article discusses the conflicts of interest that arise in the course of activities of an insurance intermediary. It is noted that the insurance broker is the generator of a conflict of interest, given the specifics of funding activities. The purpose of this article is to analyze possible sources of conflict of interest of insurance intermediaries, in the process of implementation of insurance services, due to the specific charge of the activities of insurance brokers and insurance agents. In the result of the study it was noted that the insurance intermediary is an institution, smoothing the conflict of interests and finding consensus between the insurance company and the client. Conflict of interest in the activities of an insurance broker in Ukraine solved only on a theoretical level. Through the ban on brokers receiving Commission. In practice, this only complicates the financing of its activities and triggers to use financial schemes, among which we highlight: the use of dual mediation, with the aim of obtaining compensation from the insurance company for the dependent or captive insurance agent, or through the conclusion of the contract consulting insurance broker – insurance company. Noted that the EU, with the aim of minimizing adverse effects of the implementation of conflict of interest in the activities of insurance brokers use transparency and prior disclosure of conflict of interests in relation to the client. New rules aimed at regulating the activities of financial intermediaries, because their lack was one of the main reasons to mislead customers regarding the content and price of insurance services or filling and the cost of insurance coverage in relation to the client's needs. Definitely that the regulation of insurance brokers in the EU, focus is on insurance coverage, honesty and integrity towards the client and respect their own best interest, and therefore, de facto obligation to put the client's interests above their own business interests. Further development of research opportunities for insurance agents to represent several insurers, would to some extent neutralize the conflict of interests in activities of insurance multi agents and to introduce the Ukrainian market of insurance services of another insurance intermediary.


A force sensing X-Y touch sensor comprising a plurality of conductive electrode rows, a plurality of electrode columns substantially perpendicular to and over the plurality of conductive electrode rows, a flexible electrically conductive cover over the electrode columns and a plurality of deformable spacers between the cover and the electrode columns, wherein the deformable spacers maintains a distance between the cover and the electrode columns. When a touch is applied to the surface of X-Y touch sensor, the flexible cover is biased toward the electrode columns and rows and changes the capacitance value thereof at the location of the touch thereto. This change in capacitance value is proportional to the force of the touch on the surface of the flexible electrically conductive cover. Therefore the location of the touch and the force thereof may be determined by how much the capacitance value changes.

Spell checkers are one of the most widely recognized and heavily employed features of word processing applications in existence today. This remains true despite the many problems inherent in the spell checking methods employed by all modern spell checkers. In this paper we present a proof-ofconcept spell checking system that is able to intrinsically avoid many of these problems. In particular, it is the actual corrections performed by the typist that provides the basis for error detection. These corrections are used to train a feed-forward neural network so that if the same error is remade, the network can flag the offending word as a possible error. Since these corrections are the observations of a single typist's behavior, a spell checker employing this system is essentially specific to the typist that made the corrections. A discussion of the benefits and deficits of the system is presented with the conclusion that the system is most effective as a supplement to current spell checking methods.

According to USDA statistics, the meat goat industry is growing at a rate of 10 percent to 15 percent a year. Yet, U.S. farmers do not produce enough goats to meet the domestic demand for goat meat. The growing demand for goat meat is due to the increasing immigration from regions of the world where goat meat is a preferred protein source. Among the largest consumers of goat meat are those from the Middle East, Latin America, and the Caribbean islands. The demand for goat meat is strongest on the East Coast and in urban areas with large ethnic populations. The introduction of the (South African) Boer goat breed in 1990 brought the first true " meat breed " to the United States. It was followed several years later by the (New Zealand) Kiko. Before the introduction of these breeds, meat production was mostly a by-product of the mohair (fiber) and dairy-goat industries. Market, or meat, goats make ideal 4-H project animals for many reasons. Generally, the purchase price of goats is small and the facilities needed to maintain goats are minimal. Goats are not that large and can be handled by 4-H'ers of all ages, even if they do not have a great deal of previous livestock experience. The market goat project will help you gain knowledge of the livestock industry in general and the meat goat industry in particular. By participating in the market goat project you will learn responsibility and money management, record keeping, livestock handling, and livestock selection skills. In order to successfully complete the market goat project, you will need the support and encouragement of your parents and 4-H leaders. However, the responsibility for the daily care, training, and grooming should be yours.


Lithium-sulfur (Li-S) batteries are facing a significant barrier due to the diffusion of intermediate redox species. Although some S doped covalent framework cathodes have been reported with outstanding reversibility, the low content of sulfur (less than 30%) limits the practical applications. To overcome the issue, the sulfur and nitrogen co-doped covalent compounds (S-NC) as a host-type cathode have been developed through the radical transfer process during thermal cracking amino groups on the precursor, and then plentiful positively charged sulfur radicals can be controllably introduced. The experimental characterization and DFT theoretical calculation certificate that the sulfur radicals in S-NC/S can expedite redox reactions of intermediate polysulfides to impede their dissolution. Moreover, the energy barriers during ions transfer also obviously decreased after introducing S radicals, which lead to improved rate performance.


Sea surface microlayer (SML) and underlying subsurface water (SSW) bacterial communities from the Baltic Sea were studied using culturing, flow cytometry and terminal restriction fragment length polymorphism (T-RFLP). Dissolved organic matter (DOM) of water samples was determined using high performance liquid size-exclusion chromatography and by measuring dissolved organic carbon. Cadmium, copper, lead and mercury were also measured from the water samples. Two methods were compared for SML sampling: metal screen (MS) and polycarbonate membranes (PCM). All sampling sites were located in the Archipelago Sea off the southwest coast of Finland. The hypothesis was that because of its unique features, such as accumulation of nutrients and pollutants and being unshaded from UV-radiation, the SML would support a different bacterial community to that of SSW. T-RFLP profiles showed differences between the bacterial community compositions of SML and SSW at most sampling sites. In addition, temporal and sampling-site-dependent differences were observed. There were no significant differences in DOM in SML and SSW samples. In most cases, the number of bacteria was slightly higher in the SML than in SSW. No significant cytotoxicity was observed in any of the water samples. Since no temporal trends were obvious, our results suggest that, although bacterial communities in the SML Archipelago Sea differ to some extent from the ones living in SSW, SML is a dynamic environment where bacterial communities possibly develop originally from bacterioplankton and change over time.


Abstract For products with an initially high failure rate, burn-in can be used to reduce the warranty cost. This paper examines the optimal burn-in time to achieve a trade-off between the reduction in the warranty cost and the increase in the manufacturing cost (as burn-in can be viewed as a part of the manufacturing process). Conditions for burn-in to be beneficial are derived for various warranty policies. A numerical example is presented.


Objective
To explore the relationship between serum cardiac ankyrin repeat protein (CARP) and hypersensitive C-reactive protein (hs-CRP), creatine kinase isoenzyme MB (CK-MB), and cardiac troponin I (cTn-I) in patients with acute ST elevation myocardial infarction (STEMI).

Methods
A total of 60 acute STEMI patients were enrolled in this study. Levels of hs-CRP, CK-MB, cTn-I and CARP were detected at ≤ 6 h, > 6~12 h, > 12~24 h, 72 h after heart attack. The Pearson correlation analysis was used to analyze the relationship between the CARP levels in each period and hs-CRP, CK-MB, cTn-I.

Results
The levels of hs-CRP, CK-MB, cTnI, CARP were significantly different at each period (F = 487.534, 683.673, 666.447, 1121.437, all P 12~24 h and 72 h were much higher than those at ≤ 6 h and > 6~12 h [(29 ± 26), (43 ± 28), (8 ± 7), (8 ± 7)mg/L, all P 6~12 h, > 12~24 h, 72 h [(40 ± 16), (124 ± 53), (374 ± 98), (108 ± 40) μg/L, all P 6~12 h, > 12~24 h, and 72 h were much higher than those at ≤ 6 h after heart attack [(7.3 ± 3.4), (10.3 ± 5.3), (6.5 ± 3.5), (3.6 ± 2.4) μg/L, all P 12~24 h increased markedly as compared at ≤ 6 h, > 6~12 h, 72 h after heart attack [(1 991 ± 538), (1 391 ± 471), (1 385 ± 407), (1 347 ± 429) kU/L, all P < 0.05]. The Pearson revealed that the CARP levels at each period were positively correlated with CK-MB.

Conclusion
CARP increased obviously in STEMI patients and can be used as a new indicator for the diagnosis of STEMI.

A method of segmenting synchronized sympathetic nerve activity has been developed for cardiovascular neural control research. The segmentation algorithm consists of three signal processing techniques which involve: (1) extracting an approximate region containing synchronized sympathetic nerve activity, (2) separating individual neural spikes from recorded compound nerve activity and (3) detecting the onset and end of each synchronized neural signals. By this process, the algorithm can precisely segment synchronized sympathetic nerve activity.


The consequential awareness in women at the advent of emerging feminist consciousness has heightened their questioning openly regarding their status in their family and society and especially doubts regarding their roles assigned to them by the patriarchal society such as a dependent daughter, wife and mother and as a member of the society. Marxist feminists see class as the ultimate determinant of women's current economic status, whereas socialist feminists view gender and class as equally powerful oppressive mechanisms in addition to focusing upon areas of sexuality and reproduction. The sharp distinction, made in the psychoanalytical feminist perspective, between woman's 'nature' and 'nurture' has had its impact on the polarization of the old feminine mystique, the angel in the house now split into feminine and feminist, but the adaptability of the remedies they all offer for the existing evils is still an unsolved mystery. Contemporary women thinkers are trying to achieve attitudinal changes by developing critiques of established assumptions about female familial roles. Yet it has been perceived by liberal feminists that, though feminists have highlighted the oppressive aspects of role-playing, the societal values have not changed as fast as women are changing. It is apt to probe whether the contemporary women writers react to the changing female attitudes towards domestic familial role-playing in such a society. The extent and the strategies of their reactions and the matters related to it also need to be analysed and hence a select study of two women novelists from varied cultural backgrounds– British : Doris Lessing and an Indian Regional Writer in Tamizh : Rajam Krishnan, is undertaken in this dissertation.

A method has been developed for quantitative and qualitative assessment of the risk of surface water pollution by nitrogen compounds based on the use of the indicator of the total content of inorganic nitrogen forms in water (Ninorg), that is,   This indicator is considered as the sensitivity coefficient kn. The choice of the indicator is dictated by the need to protect waters from pollution caused by nitrogen compounds during their flow from agricultural sources (Directive 91/676 /EU). The experience of developed countries has shown that nitrogen compounds deteriorate the quality of water and prevent the achievement of a "good ecological state" of water bodies. For territories with developed agriculture, it is important to establish environmental risks of damage depending on the degree of nitrogen pollution. Quantitative assessments of environmental risk are provided on the basis of a probabilistic approach. The risk was calculated as the product of the probability of a hazardous event occurring multiplied by the consequences of this event. The consequences of river pollution with nitrogen compounds were assessed as the ratio of the total concentration of nitrogen compounds (sensitivity index kn) to its threshold value (50 mg/dm3 or 11.3 mgN/dm3). In order to develop a scale for qualitative and quantitative risk assessment, relationships were established between the sensitivity indicators kн and the risk indicators R' for individual rivers, and for the study area as a whole, by means of spatio-temporal generalization. The probabilistic characteristics of possible environmental damage were determined on the basis of the obtained regression equations of the form R'=f(kn) and the statistical law of distribution of the risk value R'. The developed method will make it possible to determine the rank of the risk zone and the probability of getting into it, depending on the given sensitivity indicator kn


Materials and methods: We retrospectively analyzed twenty seven cirrhotic patients (23 men, 4 women; mean age, 61.1 years) with fifty locally treated HCCs. Two independent radiologists separately interpreted the breath-holding DW images with multiple b values (0, 500, 800, and 1000 sec/mm) and conventional MR images including T2-weighted, T1-weighted gradient echo images, and dynamic contrast-enhanced T1-weighted images and sorted the confidence levels for the presence of perilesional viable tumor in the vicinity of treated lesions into five grades in both sessions. Reference standard for the presence of viable tumor was obtained from pathologic data (n = 5) and follow-up imaging results (n = 22). The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of DW images and conventional MR images were compared using Mann-Whitney U test. Interobserver agreement was obtained using Cohen's kappa statistics.


The aim of the studies and researches - By the performed researches, the need to recalculate the elements of irrigation regime depending on the possible climatic changes, which could affect Romania, in the future, as well as the possibility of low limited water supply, in the context of the climate modifications. Stage of the research - The global warming is a phenomenon unanimely accepted by the international scientific community, being already emphasized by the observation data analysis, during long periods. The simulations achieved by global climatic models underlined the fact that the main factors which determine this phenomenon are both natural (variations of sun light and vulcano activity) and anthropogeneous ones (changes in atmosphere compositiopn due to human activities). Materials and methods - To achieve the proposed objectives, the paper presents three possible climatic scenarios, such as: 1.Tn - current average temperatures; 2.Tn+2 o C - increasing, with 2 o C, of the current average temperatures, 3.Tn+5 o C - increasing, with 5 o C, of the current average temperatures. The need to apply irrigation for a certain area was established depending on the moisture deficit calculated as difference between water consumption and supply sources for both soil and crops. The ETRO value was highly precisely estimated, using Thornthwaite method, and to follow all the modifications of the elements of irrigation regime, the water soil balances for all crops under study were achieved. Novelty degree - The paper tries to underline the negative impact of global warming, as well as to find practical solutions for farmers to counteract the drought effects. Stage of achievements - Following the researches on world plane, measures to limit the alert rhythm of climate change were taken. The measures were discussed in international summits, as those of Kyoto and Copenhagen. Limits of the research - To achieve the researches, indirect methods to determine the water consumption were used due to lack of modern equipments. Practical implications of the research - The proposals are very important for irrigated farming, because it is important to produce a lots and cheap, for food security. Paper originality - The paper presents high level of originality, no similar papers were performed till present, in Romania. Importance of the paper - The modification of elements in irrigation regime could lead to devastating economical effects for Romania's agriculture. Following increasing of average temperatures, there could be catastrophic effects, even as danger for human beings, under the current economical context


The Southern High-Speed Line (HSL), in Dutch known as 'HSL-Zuid,' is a dedicated 125 km high-speed rail line, forming part of a new route between Antwerp, Belgium and Amsterdam. Construction began in 2000, and major engineering projects include the 7.2 km tunnel Leiderdorp-Hazerswoude under the 'Gr en Heart,' an agricultural area between the country's four largest cities, Amsterda m, Rotterdam, The Hague and Utrecht. North of this tunnel, a section of the line near th e city of Rijpwetering, containing the sharpest curve on the entire route, experienced significant structural deformation during the construction stage due to ground instability, and 8 00 m of the line had to be rebuilt. Local insitu surveys show that up to 19 mm of horizontal de formation occurred after the reconstruction stage in 2006. Here we investigate w h ther local deformation of this kind can be observed by satellite radar interferometry, usin g a fine-tuned processing approach dedicated for this application. We report on the pr ocedure followed, on the constraints in the parameter estimation and the obtained level of prec ision and reliability. The combination of a forward model to simulate radar observations from i n situ measured displacements and an inverse model using the satellite data to estimate the displacements will be presented.


Abstract Introduction: The number of publications concerning mesenteric Doppler sonography (mesDS) is immense and does not correlate with the frequency of its use in clinical practice. This is astonishing since it provides real time blood flow (perfusion) information without side effects. Despite uncontrollable parameters like the technical limitations in some situations the optimization of (possibly) controllable parameters like standardization, production of normal values and reduction of the investigator variability by evaluating stable parameters could change the situation. Patients and methods: 10 investigators experienced in abdominal sonography ("DEGUM-Seminarleiter") performed mesenteric Doppler sonography in 5 healthy subjects with 5 different machines. Results: The portal vein at the confluence and the common hepatic artery provide a significant portion of investigations with intromission angles of more than 60°. Values of diameter, resistance index and pulsatility index of the celiac trunc could be obtained with inter-observer variability values below 25 %. The proper and the common hepatic artery show no differences in inter-observer variability values, whereas the intrahepatic measure point of the portal vein showed a higher reproducibility. Discussion: We define frame conditions for future mesenteric Doppler studies: the portal vein should be investigated at the intrahepatic measure point. Pathophysiological studies should refrain from velocity parameters except in the case of larger vessels running in a straight course towards the probe.

A rapidly growing number of voices argue that AI research, and computer vision in particular, is powering mass surveillance. Yet the direct path from computer vision research to surveillance has remained obscured and difficult to assess. Here, we reveal the Surveillance AI pipeline by analyzing three decades of computer vision research papers and downstream patents, more than 40,000 documents. We find the large majority of annotated computer vision papers and patents self-report their technology enables extracting data about humans. Moreover, the majority of these technologies specifically enable extracting data about human bodies and body parts. We present both quantitative and rich qualitative analysis illuminating these practices of human data extraction. Studying the roots of this pipeline, we find that institutions that prolifically produce computer vision research, namely elite universities and"big tech"corporations, are subsequently cited in thousands of surveillance patents. Further, we find consistent evidence against the narrative that only these few rogue entities are contributing to surveillance. Rather, we expose the fieldwide norm that when an institution, nation, or subfield authors computer vision papers with downstream patents, the majority of these papers are used in surveillance patents. In total, we find the number of papers with downstream surveillance patents increased more than five-fold between the 1990s and the 2010s, with computer vision research now having been used in more than 11,000 surveillance patents. Finally, in addition to the high levels of surveillance we find documented in computer vision papers and patents, we unearth pervasive patterns of documents using language that obfuscates the extent of surveillance. Our analysis reveals the pipeline by which computer vision research has powered the ongoing expansion of surveillance.


Abstract The stability of quasi-geostrophic β-plane flow over topography is examined. The approach is to first calculate the stationary, asymmetric response to a uniform zonal current flowing over topography, and then calculate the stability properties of the total, zonally asymmetric, field. Under many circumstances this flow is unstable, barotropically and or baroclinically particularly if the asymmetric flow is of large amplitude. This is demonstrated first using a long-wave approximation, which examines the stability with respect to perturbations of large meridional scale. So-called form-drag instability then ensues. This may be thought of as a special, nonlocal, form of isosceles triad interaction involving the zonal flow interacting with the topography and another "free" mode of topographic scale. For topography consisting of a single Fourier mode, instability then arises only if the zonal current is eastward and exceeds that required for resonance. However, in general other triads exist in which th...

The authors' research established statistically reliable accumulation of humus and biogenous elements in the soil top layers both under the wood, and on the virgin sites, being characterized by the maximum ecological stability, soil-protective and water preserving value.


In this paper, we study the problem of time reversal imaging of a dielectric object embedded inside another dielectric cylinder. The forward problem is solved using numerical simulation of scattering from a cross section of a cylinder by COMSOL and the multistatic data matrix (MDM) is obtained. The background Green's function (DGF) is computed by that of a point source near an infinitely long dielectric cylinder and TR-DORT is evaluated using this background DGF. Results demonstrate that while using a homogeneous DGF for imaging yields erroneous results, employing this Green's function the scatterer inside the cylinder is correctly imaged. Furthermore, small variation in permittivity of embedded dielectric cylinder is detected by studying the largest eigenvalue of the MDM matrix.

In order to study strength and evaluate its quality of cement-soil in on-site construction process, unconfined compressive tests and triaxial CU shear tests were carried out on cement-soil core samples. The analysis of effects of cement mixing content, water cement ratio and lifting speed on strength and deformation properties of cement-soil was made. The results show that with the improvement of cement mixing ratio, the strength of cement-soil core samples is enhanced obviously, deformation modulus increases significantly, but the failure strain decreases, brittleness increases. And in the same conditions of cement mixing ratio, the strength of cement soil is higher when water cement ratio is 1.0 than that when water cement ratio is 0.8. And as the lifting speed increases, the density and strength of cement soil core samples are significantly reduced. This paper introduces the concepts of standard value, variable coefficient and modulus ratio, which can evaluate the density of cement soil core samples, unconfined compressive strength and the triaxial CU shear strength. This paper gives rational advice and is certain guide significance for practical projects.


The PBMR company is developing a new generation power plant that uses a high-temperature gas-cooled nuclear reactor. The gas from the reactor is used directly to drive the turbo machines in a closed-circuit Brayton cycle. The plant is simulated by a complex thermo-hydraulic model that is used extensively in the controller design phase. This paper describes a simplified model of the plant that was developed to further assist with the design of the power control loop. Copyright © 2002 IFAC.

This study is an account of one school's attempts to investigate and develop an alternate structural model by utilizing the basic tenets of differentiated staffing. The period from September 1973 to July 1975 represents the time frame. Key events, decisions and developments drawn from this time frame have been recorded. The researcher has followed events from the inception of the idea of differentiated staffing at Piedmont Technical Institute, a member of the North Carolina Community College System, through the construction of a complete model that may be implemented in a technical institute/community college. This case is intended to lead to the implementation and evaluation stages.


The dyeing of modified pulp, particularly with regard to the mechanism involved, was studied. The reaction mechanism for the modification of cellulose fibres in aqueous solution by cationic agents was also described. The results obtained were expressed in the form of adsorption isotherms. The capture of molecules, colloidal particles, etc. during the adsorption processes involving modified pulp could be explained by two possible mechanisms: (i) aggregation (coagulation or flocculation) in solution followed by adsorption and (ii) surface aggregation (coagulation or flocculation). Surface aggregation appeared to be the most likely for pulp with a low degree of modification. The typical Langmuir adsorption isotherm correlated the data obtained for unmodified pulp very well.


Abstract : A statistical analysis was made of the jet-stream complexes (two or more jet streams existing simultaneously at different altitudes) observed at 35 aerological stations in Southern USSR in the 1961-1963 period. Only those jet streams whose speed equalled or exceeded 60 m/sec (216 km/hr), and periods when two wind peaks existed simultaneously at different levels, were taken into consideration. Instances of three or more simultaneously-existing peaks were handled separately. The Dzhordzhio jet-stream classification was adopted for the analysis, but with the exception of lower stratospheric streams, higher-level streams were omitted. In 1959 there were only 42 occurrences of jet-streams complexes and in 1960, only 34. However, the number jumped to 235 in 1961; this increase was attributed to improvements in the radar observation techniques used by 1961, and to the fact that high-speed jet-stream complexes actually were more frequent to that year. Monthly statistics are given for the three years. Number of periods in which dual jet streams were observed. It is concluded that jet-stream complexes occur frequently enough to be considered normal aeroclimatic phenomena. (Author)


Customer engagement has been increasingly recognised as a measure of corporate performance. Several practitioners and researchers have proposed various customer engagement concepts. The concept of engagement has been discussed earlier in academic fields such as psychology and education
 before the notion of customer engagement became popular. However, researchers across disciplines have not reached a consensus on the implications, the factors that constitute engagement and the measures of engagement. Therefore, inconsistencies in the interpretations of engagement have complicated
 the use of the customer engagement concept to understand complex customer behaviours and to measure customer–company relationships. In this context, the present study summarises the differences in the interpretation of engagement concepts across disciplines, and identifies the sources
 of difficulty in interpreting engagement. The study develops a framework in terms of definitions, measurement methods and scales, research methods, and constructive concepts to better understand the concept of customer engagement.


We demonstrate a new method, microarray-assisted bulk segregant analysis, for mapping traits in yeast by genotyping pooled segregants. We apply a probabilistic model to the progeny of a single cross and as little as two microarray hybridizations to reliably map an auxotrophic marker, a Mendelian trait, and a major-effect quantitative trait locus.


The fibrous overgrowths of the gingiva with calcifications have been documented in the literature under an array of terms one of them being peripheral ossifying fibroma. Here we discuss an unusual presentation of a case of recurrent peripheral ossifying fibroma in a 13-year-old girl, who reported to the department of oral pathology. The primary lesion was diagnosed as pyogenic granuloma and the recurrent lesion as peripheral ossifying fibroma. The POF might have developed as initial lesion with scarcity of ossification and was misdiagnosed as pyogenic granuloma. Though the possibility exists that the lesion is reactive in nature, but based on history of the lesion and the vicinity of the gingiva, the lesion falls into the category of focal reactive overgrowths. This case report is to analyse as to whether these two lesions represent the evolutive phases of the spectrum of the same pathosis. Annals of Dental Research (2012) 2(1), 36-43


We present the design and experiments from a testbed im- plementation of multi-source mobile video streaming that combines three mechanisms: 1) load balancing among dierent paths from multiple sources, 2) resilience to link and server failures, and 3) enhanced of- oading by exploiting mobility and throughput prediction to prefetch video data in caches located at hotspots that the mobile will encounter. Our testbed consists of an Android mobile video streaming client that can utilize both cellular and Wi-Fi interfaces and request dierent parts of a video from dierent servers, a server that accepts client requests for parts of a video, and a cache server that accepts client requests to proactively fetch parts of a video so that they are immediately available when the mobile client enters the cache server's hotspot.


Objective:To study the expression and correlation of c-erbB-2 and PTEN in endometrial carcinoma. Methods: S-P immunohistochemistry was used to measure the protein expressions of c-erbB-2 and PTEN in normal endometrium of proliferative phase, endometrial atypical hyperplasia and endometrial carcinoma. Results: The positive expression rate of c-erbB-2 in normal endometrium of proliferative phase, endometrial atypical hyperplasia and endometrial carcinoma were 0, 40% and 58% respectively; and those of PTEN were 100.0% and 60.0% and 25.8% respectively. The positive expression rate of c-erbB-2 in endometrial carcinoma and the histological differentiation were positively correlated ( P0.05). There was no correlation between the expression rate of c-erbB-2 and PTEN in endometrial carcinoma. Conclusion: There is a correlation between the positive expression of c-erbB-2 and poor prognosis of patients. The deletion of PTEN expression may play a role in the earlier happening of endometrial carcinoma. In the happening of endometrial carcinoma, the inverse coordination with c-erbB-2 and PTEN is also uncertain.
