In this paper, a novel blind watermarking scheme for still image based on the two-dimensional discrete wavelet transform (DWT) is proposed. In the scheme, digital watermarking with a pseudo-random sequence is derived from a full Logistic map system, and the robustness is achieved by embedding every bit of watermark sequence several times in many different locations in approximate sub-band of one-level Haar wavelet decomposition. The strength of watermarking is adjusted by an auto-adaptive way for fidelity constraints. During detection process, by use of the statistic characteristic of sub-band LL coefficients and the maximum subjection principle, the watermarking is extracted reliably without recurring to original image. Simulations demonstrate that the proposed method can resist many kinds of signal processing attacks such that JPEG compression, additive noise, linear filtering, format conversion, cropping and slight geometric distortion, and so the proposed algorithm has high robustness.


This paper explores the research issues related to personal computing within the corporate environment. A definition of personal computing is first offered, followed by an examination of how it relates to other areas, such as distributed processing, database management, office automation, software engineering, and artificial intelligence. Finally, specific research issues that are fundamental to the further development of the personal computing field are presented.


A 32-year-old pregnant woman complained of palpitation and syncope caused by paroxysmal ventricular tachycardia. The electrophysiological study was normal. The evidence that catecholamines were extremely increased in urine suggested that this arrhythmia resulted from imbalance in the autonomic nervous system. Medication by beta-blocking drugs during pregnancy decreased the frequency of ventricular tachycardia. In order to avoid the increase of catecholamines during the delivery, lumbar epidural anesthesia was administered, which resulted in painless vaginal delivery and impeded the attack of ventricular tachycardia. Although the baby was small for date, fortunately he was delivered normally.


Semantic segmentation for 3D point clouds plays a critical role in the construction of 3D models. Due to the sparse and disordered natures of the point clouds, semantic segmentation of such unstructured data yields technical challenges. A recently proposed deep neural network, PointNet, delivers attractive semantic segmentation performance, but it only exploits the global features of point clouds without incorporating any local features, limiting its ability to recognize fine-grained patterns. For that, this paper proposes a deeper hierarchical structure called the high precision range search (HPRS) network, which can learn local features with increasing contextual scales. We develop an adaptive ball query algorithm that designs a comprehensive set of grouping strategies. It can gather detailed local feature points in comparison to the common ball query algorithm, especially when there are not enough feature points within the ball range. Furthermore, compared to the sole use of either the max pooling or the mean pooling, our network combining the two can aggregate point features of the local regions from hierarchy structure while resolving the disorder of points and minimizing the information loss of features. The network achieves superior performance on the S3DIS dataset, with a mIoU declined by 0.26% compared to the state-of-the-art DPFA network.


Natural fibers are widely used for reinforcement in polymer composite materials and proved to be effectively replacing synthetic fiber reinforced polymer composites to some extent in applications like domestic, automotive and lower end aerospace parts. The natural fiber reinforced composites are environment friendly, have high strength to weight ratio as well as specific strengths comparable with synthetic glass fiber reinforced composites. In the present work, hybrid epoxy composites were fabricated using calotropis procera and glass fibers as reinforcement by hand lay-up method. The fibre reinforcement in epoxy matrix was maintained at 20 wt%. In 20 wt% reinforcement of fibre, the content of calotropis procera and glass fibre were varied from 5, 10, 15 and 20 wt%. The dry sliding wear test as per ASTM G99 and three body abrasive wear test as per ASTM G65 were conducted to find the tribological properties by varying speed, load, distance and abrasive size. The hybrid composite having 5 wt% calotropis procera and 15 wt% glass fibre showed less wear loss in hybrid composites both in sliding wear test as well as in abrasive wear test which is comparable with 20 wt% glass fibre reinforced epoxy composite which marked very low wear loss. The SEM analysis was carried out to study the worn out surfaces of dry sliding wear test and three body abrasive wear test specimens.

The use of GNSS for many high accuracy applications is continuously increasing. Most of the methodologies of GNSS data processing are based on the observations collected by conventional (geodetic and low cost) receivers. These devices are rather sophisticated, but appears as black boxes to the user: basically, the user does not have any access to the internal structure of the receiver. In this respect, a new class of devices has been recently proposed: the so-called Software Defined Receivers (SDRs). Up today, the use of SDR is still limited for experimental receivers, but their development, their very low cost and their flexibility have opened new possibilities including high precision applications. In this work, the variometric approach (implemented in the VADASE software) is applied to single frequency phase observation obtained from the open source multiconstellation GNSS-SDR software receiver. The final aim of this work is twofold: one hand it evaluates the reliability of GNSS-SDR phase observations, on the other hand it asses VADASE reachable accuracy when applied to phase observation retrieved by a SDR. To these aims some tests were performed and an accuracy at the decimeter level was found. The obtained results show that in the next future SDR will have an important role in GNSS scientific applications, going beyond the limits imposed from conventional GNSS receivers.


The Henry's law constants for 26 polychlorinated biphenyl (PCB) congeners were measured using a gas-stripping apparatus at five environmentally relevant temperatures between (4 and 31) °C. The Henry's law constants ranged between (0.079 ± 0.003) Pa·m3·mol-1 for 2,2',3,3',4,4',5,6-octachlorobiphenyl (IUPAC congener #195) at 4 °C and (308 ± 29) Pa·m3·mol-1 for 2,2',3,3',4,5',6,6'-octachlorobiphenyl (IUPAC congener #201) at 31 °C. The temperature dependence of each PCB congener's Henry's law constant was modeled to calculate the enthalpy and entropy of the phase change between the gaseous and dissolved phases. For many PCB congeners, this study reports the first experimentally measured temperature variations of their Henry's law constants. The enthalpies of phase change (ΔHH) ranged between (14.5 ± 3.4) kJ·mol-1 for 2,2',4,6,6'-pentachlorobiphenyl (IUPAC congener #104) and (167 ± 13) kJ·mol-1 for 2,2',3,3',4,4',5,6-octachlorobiphenyl (IUPAC congener #195). These data can be used to predict PCB congener Henry...


In the practice of buying and selling crabs in the village of Meunasah Paya, the fishermen sell all the crabs they catch without sorting them out, whether they are small, large, laying eggs or not, and this is not in accordance with Permen KP number 12 of 2020 which only allows crabs above. 150 grams and crabs that are not in egg-laying condition. The formulation of the research problem is how the practice of buying and selling crabs in Meunasah Paya village, Manyak Payed district, Aceh Tamiang district and how is Sad Adz Dzariah's review and Regulation of the Minister of Maritime Affairs and Fisheries of the Republic of Indonesia Number 12 of 2020 on the practice of buying and selling crabs in Meunasah Paya village, Manyak Payed district, Aceh district Tamiang. The purpose of the study was to find out the practice of buying and selling crabs in Meunasah Paya village as well as a review of Sad Adz Dzariah and KP Ministerial Regulation number 12 of 2020 on the practice of buying and selling crabs in Meunasah Paya village, Manyak Payed district, Aceh Tamiang district. This research includes field research (Field Research) with qualitative descriptive analysis method. The results of the study concluded that in Meunasah Paya village, crab fishermen sell all the crabs they catch to collectors without looking at the standardization of Ministerial Regulation No. 12 of 2020 which has been determined whether large or small crabs, laying eggs or not, will still be sold to collectors. According to sad adz dzariah, the law of buying and selling crabs in Meunasah Paya village is divided into two, namely some are prohibited because they are not in accordance with the candy and this will damage the crab population in nature and some are not prohibited. Meanwhile, according to Permen KP Number 12 of 2020, the sale and purchase of crabs in the village of Meunasah Paya is also divided into two, namely, some are appropriate and some are not.


In this paper, an analytical method is presented to calculate the fluid-structure coupling vibration of an elastically restrained circular plate. The displacement of the plate is expanded in series of dry mode shapes and the motion of the fluid is described by velocity potential function. Considering the equilibrium differential equation of the plate and the velocity continuous conditions at the interface of fluid and structure, the Galerkin method and expansion of Fourier-Bessel series are used to establish the governing equations of the system. The free vibration characteristics of the circular plate in contact with fluid are studied and the present method is verified by comparison with numerical results. Furthermore, the influence of spring stiffness and fluid depth on the free vibration characteristics of the circular plate is investigated.


Purpose – The future growth of international tourism is challenged by concerns of political instability, safety, socio‐economics and environmental impact. Furthermore, globalization has increased competition in tourism markets, and destinations are exposed to tough price competition on homogenized products by rivals worldwide. Given these challenges and the desire by locales for sustainable tourism development, human resource development is critical to the success of tourism in many markets. As countries and regions invest more in higher education for tourism, many of them seem to be launching these programs in English to broaden their market appeal. However, the market for higher tourism education in English (HTEE) is highly competitive and progressively global, so launching a program in English opens a school to greater competition as a price for reaching a wider audience. The purpose of this paper is to look at how tourism, wealth and higher education are linked, and how the location of HTEE is related...


This article extends recent work on the relationship between personality and career self-efficacy by examining relationships across two new inventories with scales for identifying human strengths. The Healthy Personality Inventory (HPI) has 17 content scales tapping an array of positive personality measures. The CAPA Confidence Inventory (CCI) has 6 broad, 27 basic, and 6 engagement styles measures of career self-efficacy. In a sample of college students, hypothesized correlations between personality and self-efficacy were generally confirmed. A number of unexpected relationships also were found, such as the HPI Creative scale predicting social and enterprising confidence. These inventories show promise for continued research, theory development, and assessment practice.


Control design can be model-based or data-based. A modelbased design can deliver a high performance controller if the implemented model is an accurate description of the plant. Inaccuracies in the model limit the controller performance and may even lead to instability. It is sometimes time consuming and costly to model the plant accurately. Moreover, if the model is complex, the controller can be too complex for real time implementation. In data-based control design, the plant modelling step is omitted. Instead, the controller is derived using experimental data. In this work, a databased control approach, called Iterative Feedback Tuning (IFT) [1], is investigated. This approach can be used to tune the parameters of a controller with a fixed structure.


ABSTRACT This paper considers estimation of the stress–strength reliability when the stress and strength follow two-parameter exponential distributions having different location parameters and a common scale parameter. All parameters are assumed to be unknown. We derive the uniformly minimum variance unbiased estimator, Bayes estimators and an affine equivariant estimator of the stress–strength reliability. We propose confidence intervals of the stress–strength reliability based on the generalized variable approach and percentile bootstrap method. We also derive an approximate confidence interval and Bayesian intervals of the reliability parameter. Numerical comparisons among the proposed estimators are carried out using intensive simulations. Illustrative examples have been given using real data sets.


Nanocrystalline silicon is a material that shows highly interesting properties for both electronic and photonic applications. Recently, it has also been employed as the core material for building optomechanical systems, showing some novel features. In this work we provide insight in the optical, mechanical and thermal properties of nanocrystalline silicon as a material platform of optomechanical crystal cavities. The results of this work, extracted by means of a combination of complementary experimental techniques, can be useful to evaluate the potential benefits as well as disadvantages of this material highly relevant for the development of nano-opto-electro-mechanical systems (NOEMS). We show that the specific microscopic nature of the nanocrystalline material has a dominant effect in the optical and mechanical losses and in the thermal properties. More specifically, we find strong correlations between the measured parameters and the volume fraction of grain boundaries, which has been tuned by adjusting the annealing temperature of the layers.


This paper explores the use and impact of experiential learning initiatives in an entrepreneurial university. Data are taken from two sources: interviews with eight academic managers and six focus groups with learners. A mix of narrative structuring and thematic analysis is used to explore the design, delivery and assessment of experiential learning. The authors apply Kolb's Experiential Learning Theory as their theoretical lens. Experiential learning evokes a mixed reaction from academic managers and students. The paper identifies three key themes (design, delivery and outcomes) which help to capture the complex mix of direct and indirect effects that experiential learning initiatives can have at both individual and institutional levels. The authors conclude that embedding experiential learning is a valuable part of the development of an entrepreneurial university.


The dynamic analysis of electrical machines constitutes a very important field of the study of electromechanical systems. In the present project we will deal with the dynamic analysis of synchronous machine that we meet in the transformation of mechanical energy into electrical. The goal of present thesis is the study of the behavior of synchronous machine in case of transient phenomena and the determination of the parameters and time constants that determine its operation in such phenomena. The characteristic parameter of transient and subtransient reactances and time constants of synchronous machines that we tried to determine, have been used about 75 years, and for many purposes. Initially, such reactances and time constants were calculated to give both machine designers, and users, of synchronous machines a first-hand knowledge of-short-circuit current magnitudes and their rate of change. Such magnitudes are important in establishing switchgear fault rating. This knowledge also enables mechanical stresses to be calculated between armature winding resulting from excessive currents that occur during electrical disturbances at or near the synchronous machines terminals. In addition, protective schemes could be devised so that relays could be correctly calibrated to trip armature or field circuit breakers, and thus remove faulted machines from the power systems.


This study aims to investigate the factors influencing the formation of organic services marketing in the tourism industry. According to the research conducted by the researcher, organic services are a new definition in the service industry. Organic services should represent high quality and health, just as organic products do. This research was conducted using a mixed qualitative and quantitative approach. The grounded theory was used in the qualitative part, through which the concepts and categories were identified in three stages of open, axial, and selective coding. Data were collected using in-depth and semi-structured interviews. The snowball sampling was used, reaching saturation with a total of 13 experts in the ecotourism and nature tourism industry. Five subcategories of influencing factors on the axial phenomenon were obtained from the qualitative method. The axial phenomenon had four subcategories itself. The results obtained from the qualitative part were examined using the quantitative method of structural equations. All five causal factors (climatic attractiveness and novelty, abundance of traditional and rural houses, experience of silence and peace, enjoyment and experience of health tourism, and people companionship and synergy of tourism) affected the axial phenomenon of the tourism industry significantly and positively.


Life Cycle Assessment (LCA) is considered as an important potential sustainable development tool in 21 century. China is the biggest coal consume country in the whole world, and the coal-fired power generation is the biggest customer. Assesses environment in it with the CLA, it will improve ecological environment and the whole global macroclimate. Software design of LCA for coal-fired power generation can easily assess all-round. It can control and analyze in quantity from raw and processed materials to final waste materials.


A nanofiber-plane-grating composite slow-light waveguide to achieve wideband slowlight propagation with no distortion is proposed. The waveguide is formed by embedding a tapered nanofiber into a V-groove on a plane-grating surface. By optimizing the waveguide structural parameters, a slow-light effect with bandwidth of about 1453 GHz is obtained. Based on finite-difference time-domain (FDTD) method, we analyze the waveguide's optical properties and slow-light characteristics. Simulation results show that a picosecond optical pulse propagating in the slow-light waveguide can be delayed for about 980 fs and without distortion. The group velocity of the optical pulse can be reduced to about 0.3c (c is the speed of light in vacuum). This study will provide important theoretical basis and innovative ideas for the development of new-type slow-light elements.


The Pacific Decadal Oscillation (PDO) is a large-scale climate system feature that influences the surface climate and hydrology of western North America. In this paper, we review the literature describing the PDO and demonstrate its effects on temperature, precipitation, snowfall, glacier mass balance, and streamflow with a focus on western Canada, and particularly British Columbia. We review how the PDO index was developed and discuss other North Pacific climate patterns that resemble the PDO. The impacts of PDO on glacier mass balance and streamflow from retrospective studies are also reviewed and illustrated with specific examples from BC. We assess the current state of knowledge regarding the PDO and provide a critical assessment of its use in hydroclimatology. This information should provide insight on the sensitivity of projects to climatic variability.


Piedra are considered asymptomatic superficial mycoses characterised by fungal growth that form nodules on the outside of hair shaft. Two types of piedra exist: white piedra (trichosporosis) caused by the basidiomycetous yeasts Trichosporon spp. and black piedra produced by the ascomycete Piedraia hortae. While the first produce soft white or light brown nodules formed by closely attached fungal elements (hyphae and arthroconidia), the second produce hard black nodules formed by a compact fungal stroma within which asci and ascospores originated. Nodules of white piedra are less fixed on hair than those of the black variety and can easily be removed. Classically it has been considered that, although neither fungal infection generally alters or destroys the keratin of hair cortex, they both disrupt the hair cuticle. Recent ultrastructural research on the course of hair infection and keratin destruction has clearly demonstrated that Piedraia hortae act as keratinolytic fungi, dissolving the cuticular as well as the cortex keratin. In this chapter we will highlight recent findings on these rare hair infections and discuss the keratinophilic and keratinolytic activity of these fungi.


This presentation demonstrates the evolution of qualitative analysis in one academic department as use of NUD*IST software increased. Most of the research conducted in the department is funded by federal grants, and thus is very focused on answering specific research questions regarding health behavior and health-related decision making in a short time frame (often less than 12 months from project start-up to project final report). While methodologies commonly used in a grounded theory approach are utilized, the research usually is based on one of a number of theories of health behavior (Social Cognitive Theory, Theory of Planned Behavior, Theory of Reasoned Action, Social Ecological Model, etc.) rather than grounded theory. Thus the researcher undertakes analysis of the focus group transcripts or interviews looking for answers to the research questions and approaches coding initially from the perspective of the theory in use in the study. Using examples from studies of women's health-related decisions at mid-life, barriers and enablers of women's participation in physical activity, evaluation of a capacitybuilding intervention, and women's analysis of HIV risk in sexual relationships, this presentation will examine how the extraction of meaning from data changed as the research teams moved from N4 to NVivo 2. Initially (N4) data were coded at appropriate nodes using the software, but extraction of meaning from the data was regarded as a manual (and quite time-consuming!) process. In the more recent studies, the NVivo Assay tool was used extensively to guide the investigation of specific relationships in the data, making the extraction of meaning from the transcripts much more efficient. In addition, the value of the Attributes in both N6 and NVivo has been more fully explored and has changed the approach to transcription from distinguishing only between moderator and participant in focus groups to identifying each speaker and using the Case function in NVivo to track each participant's contributions to the discussion. Though evolving, the research teams have not yet utilized the Merge program in NVivo and reasons for this reluctance will be discussed. Actual examples from these projects showing the evolution of our qualitative analysis will be shared in this presentation.


The evolution of oil during pyrolysis of blocks and powders of oil shale has been investigated using heating rates from 2 to 180/sup 0/C/h. Blocks (in the form of right circular cylinders) ranged from 3.2- to 17-cm dia, and from 14 to 49 gal/ton in grade. The results show that coking reactions are the major source of intraparticle oil degradation. Furthermore, the degree of coking depends strongly on the heating rate but is nearly independent of particle size and grade for the conditions used. For example, at a heating rate of 2/sup 0/C/h, 83 percent of Fischer Assay oil is collected, whereas at a rate of 180/sup 0/C/h the yield is 99 percent. These results are the same (to within +-2 percent) for both powders and 17.2-cm dia blocks. The experimental results from the 17.2-cm blocks are analyzed using a simple mathematical model based on kinetic results from powder retorting experiments and thermal data reported in the literature. The model calculations for the rate of oil production, the degree of oil degradation, and the thermal profile through the material are found to agree very closely with the experimental data. Finally, the practical implications of this work toward field retorting are more » discussed. « less


This study determined the comparative impact of Moringa oleifera and Carica papaya leaves powder on some life stages of clarias gariepinus. 2,400 fry of Clarias gariepinus fish from the same stock were randomly stocked at 200 fish per plastic aquaria at 3 treatment levels designated control (0.00), 0.10g/l, 0.20g/l , 0.30g/l each with 4 replicates representing the treatment levels. The experiment was carried out for 8 weeks. The result obtained respectively showed that after 2, 4 and 6 weeks culture period the highest survival rate: of fry in Moringa oleifera treated aquarium at 0.10g/l was 86.35%; of post fry was 60% and of fingerlings was 60% while with Carica papaya it was observed that the highest survival rates recorded at 2, 4 and 6 weeks were respectively 63.75% for fry, 57.00% for post fry and 57.00% for fingerlings at 0.20g/l when compared to the control (2 weeks – 37% survival; 4 weeks – 25% survival and 6 weeks – 20% survival). These leaves at their respective doses as prescribed by this research are therefore suitable for raising young fishes since it appears that the anti-oxidant content of these plants arrests the hydroxyl radicals within the water body which takes care of the oxidative stress generally responsible for high level mortality in fish breeding.


The present invention relates to a pharmaceutical composition comprising an antimalarial agent selected from the group consisting of artemether, arteether, artemisinin, dihydroartemisinin and artesunate; sulfamethoxypyrazine; and a dihydrofolate reductase inhibitor and further comprising one or more pharmaceutical acceptable excipients, carriers and/or diluents suitable for providing treatment of malaria in a period of one day.


approvedThe operation of alternating-current thin-film electroluminescent (ACTFEL) de vices may be strongly affected by the presence of dynamic or static space charge in the phosphor layer during device operation. Dynamic space charge is a positive space charge which is periodically created and annihilated in the phosphor layer during each cycle of the applied voltage waveform. Static space charge is a pos itive space charge which, once created, essentially remains in the phosphor layer throughout the subsequent operation. The accomplishments presented in this thesis are the development of a method for estimating the density of static space charge in evaporated ZnS:Mn ACTFEL devices by comparing the average phosphor field under field-clamping conditions. The results presented indicate that the static space charge density for evaporated ZnS:Mn ACTFEL devices is approximately 7.7-14.4 mC/cm3 which corresponds to an ionized trap density of 4.8-9.0 x 1016 cm-3. Also presented is evidence that the phenomenon known as relaxation charge is a bulk ef fect, as it scales with the phosphor thickness, and also that overshoot in transferred charge measurements is largely due to overshoot in the relaxation charge. Finally, a novel transferred charge technique is presented in which the ACTFEL sample is electrically reset to the same starting conditions in terms of polarization charge and field prior to the measurement of the transferred charge. These electrically reset transferred charge measurements show different characteristics than the standard transferred charge characteristics, most notably in the lack of overshoot.

A 2½-dimensional, steady state model of the low-latitude boundary layer (LLBL) on closed field lines has been developed. Coupling to the dayside auroral ionosphere via region 1 field-aligned currents and associated finite field-aligned potential drops is included. The boundary layer (BL) flow is influenced by viscous forces, inertia forces, pressure forces, and j × B forces. The BL approximation and kinematic treatment of the plasma motion perpendicular to the equatorial plane greatly simplify the model. The model has three modules: an equatorial LLBL module, a force-free coupling module, and an ionospheric module. It includes nonconstant magnetosphere-ionosphere mapping factors, describing the increasing stretching of magnetic field lines with increasing distance away from the subsolar region, as well as variations in mapping factors across the BL. In this paper, both the BL height and the ionospheric conductivities are assumed constant. The effects of finite field-aligned potential drops and nonconstant mapping factors on the BL flow, on the plasma density and temperature, on the magnetic field line bending, and on the field-aligned current distribution are presented. The effects of varying the magnitude of the (constant) ionospheric Pedersen conductivity are also discussed. In addition, the effects of viscosity, including varying its magnitude and allowing it to be a function of location both along and across the LLBL, are examined. A number of qualitative features of the simulation results are found to be consistent with various observations.

Background Juvenile Fibromyalgia Syndrome (JFMS) is a chronic health condition characterized by widespread musculoskeletal pain and multiple tender points (TP). The objective of this study was to determine the prevalence of JFMS in the urban population of Samsun and to determine the impact of JFMS on depression symptoms, school performance and quality of life (QOL). Methods A cross‐sectional study was conducted in 1109 children (mean age (14.8±2.0) years old). A questionnaire was applied to the children and a medical examination including TP was performed. Yunus and Masi's criteria were used for diagnosis of JFMS. The children with JFMS were compared with an age and sex matched non‐JFMS group. Depression was assessed with Children's Depression Inventory (CDI) and QOL was evaluated with Pediatric Quality of Life Inventory 4.0 (PedsQL4.0). Results Sixty‐one (5.5%) (13 boys and 48 girls) of 1109 children met the diagnostic criteria of JFMS. While PedsQL scores of children with JFMS were lower than the non‐JFMS group for physical, emotional, social, school functioning and total score (P=0.001), CDI total score was higher in the JFMS group than in the non‐JFMS group (P=0.001). The JFMS group reported more school absences (P=0.001) and the average school grade was lower in the JFMS group than in the non‐JFMS group (P=0.03). Conclusion The prevalence of JFMS is high in school age children. Since JFMS is a common problem of childhood, early diagnosis and identification of the disorder and more comprehensive and successful treatment approaches with appropriate psychological assistance may prevent more complex and severe problems in adulthood.


Jump was commissioned by Dutch bass clarinet virtuoso Henri Bok. The work weaves a contrapuntal structure from a single line by means of extensive registral partitioning through the particular agility of the bass clarinet with large interval leaps. In addition, the technique of "tonal stratification" is employed, in which functional linear harmony is vertically stratified.

The present invention relates to a silicone hydrogel lens with excellent oxygen penetrating power obtained by polymerizing N-vinyl-n-methylacetamide, silicone (3-methacryloyloxy propyltris (trimethylsilyloxy) silane), a fluorine compound (trifluoroethyl methacrylate) monomer, and a croslinking agent using 2-hydroxyethyl methacylate as a base on a contact lens.


Elk (Cerous elaphus nelsoni) that summer in Grand Teton National Park (GTNP) are part of the migratory Jackson Elk Herd. They are fed in winter on the National Elk Refuge (NER) and have been hunted in portions of GTNP since 1950 to control population size. However, the number of elk in the Jackson Elk Herd has grown from about 8,000 in 1984 to >16,000 in 1997. We captured and radiocollared 164 newborn calves during 1990-92 to quantify juvenile mortality and its role in regulating the Jackson Elk Herd. Elk captured in GTNP (5.9 elk/km 2 ) and on adjacent national forest lands of lower elk densities (2.4 elk/km 2 ) were radiomonitored through May 1994. Mortality of calves was similar during summer (15.2%), fall (15.3%), and winter (16.5%) 1990-92. Most deaths resulted from predation, hunting, and winter mortality associated with increased precipitation, duration of winter, and epizootic disease. Survival of calves supplementally fed in winter exceeded survival of calves not fed (P = 0.039). All but 1 of 16 deaths of elk ≥1 year old (n = 122) resulted from hunting. Early-born calves experienced higher winter survival (P = 0.02) than late-born calves. Annual calf survival (x = 0.579) was inversely related to birth date (P 0.47). Because much of the variation in juvenile survival was density independent, we recommend management that reduces the dependence of elk on supplemental feed and increases harvests of female elk.

"Go! Hula " is a film about 'Female Awakening'. This is a story about a brave woman, often subjected to domestic violence, and how she found real happiness through her participation of a Hula dance competition. Despite her husband's gambling habit and violent behaviors She insists to stay on with her children. With endless pressure day in day out, she has long lost her desire to chase so many lifetime dreams. Then, she met some friendly dance mates and was invited to join the competition, hoping to win the first prize to pay for her son's graduation trip. With so many help from her best friends as well as the spiritual influence from the Hula dance, she is on her way to a journey that is about to change her life all over. A minor misunderstanding, however, nearly broke up the team, but in the end their courage, perseverance and mutual trust prevailed. They became great partners again and after the competition went on to seek their new self and a brand new future together. A story about female awakening, but it also seeks to explore personal breakthrough from unselfish friendship, group help, perseverance and sharing of individual successes (or hero's journey). This study tries to examine the film itself not only via feminism, three-act structure of Hollywood drama, the mythological archetype, Marslow's hierarchy of needs, it also seeks to assess the execution of film style, aesthetics, pre-production, production, post-production and marketing.


Observations on skin histamine suggest that histamine plays a part in a number of skin diseases ot" inflammatory or allergic nature (5) . Histamine, however, is no longer considered the only chemical mediator in these conditions. Serotonin, although probahly of greater importance in the rat than in man, and kinin peptides may also contribute (2, 6) . Antiamine is a new term characterising drugs which possess not only antihistaminic properties but also antagonize other biogenic amines and possibly also kinin peptides such as bradykinin. The present study offers a comparison of the effect of two antiamines, BP 400 and cyproheptadine, as well as the effect of a new antihistamine drug HS 592, on histamine, serotonin and bradykinin induced weals.


Measurements in a neon discharge are presented which suggest the existence of a similarity relation between the values of E λ, pD and i/D for the ionization waves of type "p" in a plasma.


Lipids, proteins, minerals and essential oils were quantitatively determined from the plant Tussilago farfara L. (Asteraceae) growing wild in Sharr (south part of Kosova). Proteins were determined according to the Kjeldahl method, whereas lipids were determined according to the Soxhlet method. Determination of the lipid fraction was performed using thin layer chromatography. Using TLC we have determined five fractions of lipids with different polarity. Essential oils were isolated using steam distillation. The mineral content of Tussilago farfara L. (Asteraceae) was investigated using Atomic Absorption Spectrometry (AAS). Seven elements, iron, calcium, potassium, magnesium, copper, sodium, and zinc, were determined in this plant. From our results we can conclude that Tussilago farafara L. (Asteraceae), growing wild in the south region of Kosova contain: lipids 1.745 %, proteins 2.477 %, essential oils 0.111 %, iron 0.912 %, calcium 0.463 %, potassium 0.295 %, magnesium 0.228 %, copper 0.081 %, sodium 0.057 %, zinc 0.0353 %. It is evident that iron is present in larger amounts in this plant compared to other elements.


The fully quantized mechanical motion of a single-level quantum dot coupled to two voltage-biased electronic leads is studied. It is found that there are two different regimes, depending on the applied voltage. If the bias voltage is below a certain threshold (which depends on the energy of the vibrational quanta) the mechanical subsystem is characterized by a low level of excitation. Above a threshold the energy accumulated in the mechanical degree of freedom increases dramatically. The distribution function for the energy level population and the current through the system in this regime is calculated.


Recent results from the CMS Collaboration are reported, covering the wide variety of probes accessible to the experiment. Presented at SQM 2017 17th International Conference on Strangeness in Quark Matter Recent results from CMS Émilien Chapon1,?, on behalf of the CMS Collaboration 1Experimental Physics Department, CERN, CH-1211 Geneva 23, Switzerland Abstract. Recent results from the CMS Collaboration are reported, covering the wide variety of probes accessible to the experiment. Recent results from the CMS Collaboration are reported, covering the wide variety of probes accessible to the experiment. The strongly interacting matter created in nuclear collisions at the LHC, in pPb and PbPb collisions but also high multiplicity pp collisions, can be studied with the means of a large variety of probes, from identified hadrons to jets, from light flavours and strangeness to heavy flavours, charm and beauty. The CMS collaboration [1] uses many different observables in these studies, starting with the production cross section. Nuclear modification factors (RAA) can also be built, from the ratio of the cross section in heavy ions collisions (HIC), pPb or PbPb, to that in pp collisions. In this way, one can clearly see if the production of a given probe is suppressed or enhanced in HIC: for instance, in the case of charmonia, colour charge Debye screening in the quark-gluon plasma (QGP) induces a suppression in the production in PbPb collisions, while recombination can also play a role and enhance the yields at low transverse momentum (pT). Much information can also be gained by focusing on collective properties of each event, such as N-particle correlations, or event-by-event fluctuations of such quantities. In particular, the Fourier coefficients of the azimuthal correlations (v2, v3, etc.) provide information on the anisotropic flow in the event (resp. elliptic, triangular, etc). A collective behaviour is observed not only in PbPb collisions, but also in small systems: pPb and even pp collisions. In dijet production, the imbalance of the two jets can be measured and compared between different systems, pp and PbPb. Heavy flavour jets, such as b jets, then allow to probe the flavour dependence of parton energy loss. 1 Charmonia The different charmonium states (J/ψ, ψ(2S )) can be reconstructed through their decay to a pair of oppositely charged muons. The invariant mass distribution mμμ of these pairs is then fitted to extract the observed yields. However, further work is needed to disentangle the different sources of charmonium production. Some fraction of it, called nonprompt, originates from the decay of B mesons, which can be resolved using the pseudo-proper decay length `J/ψ, reconstructed using the distance between the primary and dimuon vertices. In the case of the J/ψmeson, a two-dimensional fit allows to simultaneously extract the prompt and nonprompt production, while in the case of the ψ(2S ) meson, a cut-based method was used to remove the nonprompt contribution. The prompt component of J/ψ meson production receives also a contribution from the feed-down from excited charmonium states, χc and ψ(2S ) mesons. This cannot be separated from direct J/ψmeson production in the results reported here. ?e-mail: firstname.lastname@example.com part N 0 50 100 150 200 250 300 350 400 A A R 0 0.2 0.4 0.6 0.8 1 1.2 1.4 (Eur.Phys.J.

This essay examines the reasons for Hegel's frequently professed claim that Kant's Critique of Judgment simultaneously reveals the internal limits of critical philosophy and opens the door to his own system of speculative idealism. It evaluates Hegel's contention that the conceptions of aesthetic experience, organic purposiveness, and the intuitive intellect developed in the third Critique together conspire to undermine the epistemological and metaphysical foundations of the theories of nature and freedom advanced in the first and second Critiques . Finally it explains how Hegel understands his logic and real philosophy as a realist and quasi-naturalistic alternative to Kant's subjective idealism, one that purports to generate a system of categories adequate not only to dead matter but also to organic life and free self-conscious spirit.


In this article, we develop an optimal control model of supply chain reconfiguration that has been previously investigated with the help of mathematical programming approach. The developed model can be used to represent the dynamics of a continuous-flow supply chain system with a hybrid discretecontinuous state space. Dynamics of the supply chain reconfiguration can be modelled more detailed using the aggregate optimal parameters determined in the mathematical programming representation. The results of this study allow to distribute parameters and variables between mathematical programming and optimal control models in order to exploit their advantages in a joint manner.

My Giants is a thirty minute documentary about two journeys to my homeland. During the first, in 2015, I documented the story of Xylella fastidiosa, a deadly bacteria responsible for the loss of many thousand-year-old olive trees in the Italian region of Puglia. During the second visit, in 2016, I witnessed the illness of my father. By weaving together the two stories—the epidemic killing the olive trees and the cancer that invaded my father—I create a snapshot of a transitional moment in my life, a moment when illness became an opportunity to reconnect with my roots. BACKGROUND AND SUBJECT Puglia, a Southern Italian region of the Mediterranean basin, has more than 60 million olive trees. These plants are smaller than a sequoia, a baobab, or an oak, but the Apulian inhabitants proudly call them "walking giants" because their peculiar shape makes them look like an army of marching trees. In fact, it is the centuries of care that people have put into these olives trees, regularly digging and removing the dying core of the trunk, that has given them their "walking" shape and allowed them to survive for hundreds, sometimes even thousands, of years. In 2013 in Salento, the southernmost area of the region, olive trees began to get sick, dry out, and die. Trees that had survived for centuries, and stared down many natural adversaries, were now succumbing to a mysterious disease. Nothing similar had happened in human memory. Almost two years later, local scientists finally identified the main culprit of the disease: Xylella fastidiosa, a non-indigenous bacteria that had never been detected


Personalized market demands make the job shop scheduling problem (JSSP) increasingly complex, and the need for scheduling methods that can solve scheduling strategies quickly and easily has become very urgent. In this study, we utilized the variety and simplicity of dispatching rules (DRs) and constructed a DR real-time selection system with self-feedback characteristics by combining simulation techniques with decision tree algorithms using makespan and machine utilization as scheduling objectives, which are well adapted to the JSSP of different scales. The DR real-time selection system includes a simulation module, a learning module, and an application module. The function of the simulation module is to collect scheduling data in which is embedded a novel mathematical model describing the JSSP; the function of the learning module is to construct a DR assignment model to assign DR combinations to the job shop system, and the function of the application module is to apply the assigned DR combinations. Finally, a series of job shop systems are simulated to compare the DR assignment model with the NSGA-II and PSO algorithms. The aim is to verify the superiority of the DR assignment model and the rationality of the DR real-time selection system.


The invention discloses a semisynthetic method of irinotecan hydrochloride. The method comprises the following steps: (1) taking 10-hydroxy camptothecin as a raw material, obtaining an intermediate 7-ethyl-10-hydroxy camptothecin by free radical reaction; (2) taking 4-piperidino piperidine as a raw material to prepare 4-piperidino piperidine formate, chloridizing to obtain 4-piperidino piperidineformyl chloride, and getting the 4-piperidino piperidine formyl chloride for the following reaction in the form of a free alkali; and 3) causing a condensation reaction between the intermediate SN-38and the 4-piperidino piperidine formyl chloride to directly obtain the hydrochloride of the irinotecan. Preparation of the intermediate SN-38 is simple and the yield is high; a side chain 4-piperidino piperidine formyl chloride participates in the following reaction in the form the free alkali, the operation is simple, the yield is increased, thus reducing the total production cost, and increasing total yield of the whole production process. The total yield of the 10-hydroxy camptothecin is up to 76% based on the 10-hydroxy camptothecin, so the method is more fit for industrialized production.


Introduction: Acute focal bacterial nephritis (AFBN), previously called acute lobar nephronia, is a rare form of interstitial bacterial nephritis in children. The majority of patients with AFBN have an underlying urinary tract abnormality. Timely initiation of appropriate antimicrobial therapy can prevent abscess formation and help avoid the need for invasive surgical procedures. Case Presentation: Here we describe a case of a 4-year-old boy admitted for a febrile urinary tract infection (UTI). Radiological investigations led to a diagnosis of AFBN. He was later found to also have a pre-existing malformative uropathy. Conclusions: Timely detection and appropriate antibiotic therapy of AFBN are essential to prevent renal abscess formation. A possible diagnosis of AFBN needs to be considered in all patients being treated for febrile UTI. Detection and surgical correction of the underlying malformation are necessary to prevent further recurrences.


The exclusive vector meson photoproduction has being investigated both experimentally and theoretically in recent years as it allows to test perturbative Quantum Chromodynamics. The quarkonium masses, mV , give a perturbative scale for the problem even in the photoproduction limit. An important feature of these processes at the high energy regime is the possibility to investigate the Pomeron exchange. For this energy domain hadrons and photons can be considered as color dipoles in the mixed light cone representation, where their transverse size can be considered frozen during the interaction. Therefore, the scattering process is characterized by the color dipole cross section describing the interaction of those color dipoles with the nucleon/nucleus target. Here, we summarize the results presented in Refs. [1] where the exclusive production of J/ψ and the radially excited ψ(2S) mesons were studied in pp and AA collisions in the LHC energy range. The theoretical framework considered is the light-cone dipole formalism, where the cc̄ fluctuation (color dipole) of the incoming quasi-real photon interacts with the nucleon or nucleus target via the dipole cross section and the result is projected in the wavefunction of the observed hadron. At high energies, the transition of the regime described by the linear dynamics of emissions chain to a new regime where the physical process of recombination of partons becomes important is expected. It is characterized by the limitation on the maximum phase-space parton density that can be reached in the hadron wavefunction, the so-called parton saturation phenomenon. The transition is set by saturation scale Qsat ∝ x, which is enhanced in the nuclear case. The predictions for ψ(2S) are somewhat new as most part of predictions in literature concern only to the ψ(1S) state.


Abstract Exposure to environmental features early in life potentially can influence the kinds of places animals select to live later in life. We examined whether there is evidence that Cooper's hawks (Accipiter cooperii) hatched in an urban environment choose sites with features similar to their natal areas when they nest for the first time. The features we examined were the nest tree species and the level of development surrounding the nest tree. We banded nestling and fledgling Cooper's hawks in Tucson, Arizona, USA, from 1994 to 2004. We then monitored nests in Tucson to identify hawks that had been hatched in the city and eventually secured a breeding site. Percent cover of buildings around first breeding nests was not related to percent cover of buildings around natal nests for either sex. There was some evidence that being hatched in a particular tree species influenced choice of tree species at first breeding sites for males, but the influence was weak. In contrast, tree species in which first-time breeders built their nests, and the sites where the trees were located relative to development, were proportional to what was available in the Tucson metropolitan area. Our data suggest that natal experience played a limited role in nest-site selection by Cooper's hawks in Tucson for the features we examined. If learning occurred, it could have been for the general structure of natal sites. Thus, any small grove of large trees planted in Tucson could be used as a nest site by Cooper's hawks regardless of the level of development surrounding the nest.


The California Attorney General found three sections of the state's nuclear regulation code to be in violation of Federal authority and the State Constitution. Legislation and court cases since 1946 are quoted to support the Attorney General's position. The Warren--Alquist Act, which requires a demonstrated technology for reprocessing fuel rods or disposing of high-level wastes before a nuclear plant can be licensed, is unconstitutional because it usurps Federal control and allows the state to permanently block nuclear facility construction and certification. States' rights in the area of radiological health and safety are supplanted by the Federal government.

The study was conducted to assess the effect of reciting "OM" word on relieving perceived stress of 30 married adults (20 males and 10 females) aged between 25 to 35 years. On the basis of Perceived Stress scale (Cohen, 1988) high stressed subjects were screened and they were asked to recite OM word daily in the morning for 10 minutes with intention and devotion and after that they were asked to relax for 10 minutes in a garden under the supervision of a yoga teacher for 21 days. After the session was over subjects' perceived stress was assessed and the mean scores of first test and the subsequent test were compared through t-ratio statistical significance test. Results showed that after recital of OM sound with intention and devotion the level of perceived stress was reduced significantly.

An efficient image categorization method based on improved distribution of local invariant features is proposed.Firstly,the distribution of local features of an image is modeled by Gaussian mixed models (GMMs).Then,initial probability signatures are established by projecting local features onto all single models of GMMs.Finally,the complete probability signatures are obtained by performing a compression process.The probability signatures retain high discriminative power of probability density function (PDF) model,and they are suited for measuring dissimilarity of images with earth mover's distance (EMD),which allows for partial matches of compared distributions.The images are classified by learning support vector machine classifier with EMD kernel.The proposed method is evaluated on three image databases in scene recognition and image categorization tasks.The results of comparative experiments show that the proposed algorithm has inspiring performance.


Background: Having a child admitted to intensive care is a highly stressful experience for parents; however there is a lack of screening instruments of parental stress in that context, which would be useful for both, research and clinical purposes. Objectives: (1) To validate a brief measure of parental stress based on the Parental Stressor Scale: Paediatric Intensive Care Unit (PSS:PICU), (2) to study which environmental factors of the PICU are more stressful in a sample of Spanish parents, and (3) to study which variables are related to higher levels of stress among this group. Method: 196 Spanish parents completed the Abbreviated PSS: PICU (A-PSS:PICU) and a general stress scale (the Perceived Stress Scale) upon their child's discharge to test the convergent validity of the tool. Three months later, they were assessed anxiety and depression using the Hospital Anxiety and Depression Scale, and posttraumatic stress with the Davidson Trauma Scale in order to test the predictive validity of the A-PSS:PICU. Results: Two factors emerged from Confirmatory Factor Analyses, (1) stress due to child's condition and (2) stress related to PICU's staff. The A-PSS:PICU showed adequate reliability and convergent and predictive validity. The most stressful aspects were the behaviours and emotional responses of their child and the loss of their parental role. Age, gender, child's condition, length of admission, spiritual beliefs, and mechanical ventilation were associated to parental stress scores. Conclusion: The A-PSS:PICU is a reliable and valid measure. Parental stress should be screened during a child's PICU admission to identify parents at risk of post-discharge distress. © 2016 Australian College of Critical Care Nurses Ltd.

Romania is a country located in Eastern Europe. It has two important seismic areas, Vrancea and Banat. Vrancea seismic region is located close to the biggest city of Romania, Bucharest, which is also the capital, while Banat seismic area is located in the western part of the country. The most important city from the Banat area is Timisoara, which was also elected to be the European Capital of Culture 2021. Beside the general seismicity of the area, which is characterised by shallow earthquakes of crustal type, Timisoara city presents also two seismic faults that cross the western part of the city. The peak ground acceleration is considered to be ag=0.20g, while the maximum recorded magnitude was MW=5.6-5.8. The paper is a part of a larger research work which aims to assess the seismic vulnerability of the historical buildings in Timisoara city and their specific failure mechanisms, through both empirical simplified and mechanical numerical analysis. This study presents a new methodology that was previously proposed by the authors in their work and that considers also the influence of the cultural value in the process of assessing the seismic vulnerability. The consideration of the architectural, artistic, urbanistic and social elements can considerably influence the seismic vulnerability of a building. The highest the cultural value, the highest the need for rehabilitation work. The study is focused on one of the most important historical buildings of the city, Elite's Palace, and compares the results of the empirical seismic vulnerability assessment with and without considering the cultural value. This kind of research could provide valuable information for the local authorities and could represent the base of a prioritization list for the future rehabilitation work.


Revision procedures for total knee arthroplasties are today frequent operations and exhibit an overproportional increase in many clinics specialising in joint replacements. With modern operating techniques and the use of modern modular prosthetic systems, many replacement situations can now be managed with both early and late functional results that are well comparable with those of primary knee arthroplasties. However, particular attention must always be paid to the logistic possibilities in the clinic and the available options of the respective prosthetic system since, especially in revision surgery of the knee, intraoperative situations can arise that necessitate an extension of the procedure. Additional options for bone replacement are possible with the techniques of trabecular metals, and these can also be employed in combination with autologous and allogenous spongiosaplasties.

Centromere association involving two or three nonhomologous bivalents at meiotic prophase of Beta vulgaris and monosomic additions of B. vulgaris × B. procumbens are described. The associations, most conspicuous at late pachytene and persisting until diakinesis, occur abundantly in a small group of genetically related plants. The presence of normal bivalents at metaphase I and the absence of irregularities at later stages show that centromere associations do not disturb meiotic recombination and transmission. A mathematical model proposed to test for randomness with respect to the number of bivalents involved in centromere associations, showed significant difference between observed and expected frequencies. On the basis of our own observations and data from the literature, it is suggested that the associations at pachytene and diplotene are delayed separations of centromere aggregates that arise at premeiotic interphase or during the formation of the synizetic knot. A possible molecular mechanism is disc...


Type‐II and multiply connected type‐I superconductors may experience magnetic forces that are significantly different from the well‐known repulsive Meissner effect. In particular flux trapped by a superconductor may result in a force which has a stable position. We have calculated the magnetic force acting on a superconductor, based on a trapped flux model; the results have been compared with experiments at 4.2 K on (1) a block of Nb3Sn, (2) a disk of YBa2Cu3Ox, and (3) a hollow cylinder of Pb. Most of the experimental results are in reasonably good agreement with the calculations. However, an interesting discrepancy exists in the frequency of small oscillations about the stable position.


We study the ideals of the rational cohomology ring of the Hilbert scheme X (n) of n points on a smooth projective surface X. As an application, for a large class of smooth quasi-projective surfaces X, we show that every cup product structure constant of H � (X (n) ) is independent of n; moreover, we obtain two sets of ring generators for the cohomology ring H � (X (n) ). Similar results are established for the Chen-Ruan orbifold cohomology ring of the symmetric product. In particular, we prove a ring isomorphism between H � (X (n) ; C) and H � orb (X n /Sn; C) for a large class of smooth quasi-projective surfaces with numerically trivial canonical class.


Nucleotide variation in an 8.1-kb fragment encompassing the RpII215 gene, which encodes the largest subunit of the RNA polymerase II complex, is analyzed in a sample of 11 chromosomes from a natural population of Drosophila subobscura. No amino acid polymorphism was detected among the 157 segregating sites. The observed numbers of preferred and unpreferred derived synonymous mutations can be explained by neutral mutational processes. In contrast, preferred mutations segregate at significantly higher frequency than unpreferred mutations, suggesting the action of natural selection. The polymorphism to divergence ratio is different for preferred and unpreferred changes, in agreement with their beneficial and deleterious effects on fitness, respectively. Preferred and unpreferred codons are nonrandomly distributed in the RpII215 gene, leading to a heterogeneous distribution of polymorphic to fixed synonymous differences across this coding region. This intragenic variation of the polymorphism/divergence ratio cannot be explained by different patterns of gene expression, mutation, or recombination rates, and therefore it indicates that selection coefficients for synonymous mutations can vary extensively across a coding region. The application of nucleotide composition stationarity tests in coding and flanking noncoding regions, assumed to behave neutrally, allows the detection of the action of natural selection when stationarity holds in the noncoding region. a normal approximation was used test dichotomized test the probability of a number of runs to or smaller than that in the data ( Comeron, The possible departure the neutral frequency for and unpre- Tajima's test Tajima D of D achieved sonal using Hudson's coalescence algorithm with recombination Hudson flow level flow between chromosomal in our case [A St ] and 2 can be inferred the ratio of to total polymorphisms ( S /


Analysis of model organisms, such as the submillimeter-size Caenorhabditis elegans, plays a central role in understanding biological functions across species and in characterizing phenotypes associated with genetic mutations. In recent years, metabolic phenotyping studies of C. elegans based on H high-resolution magic-angle spinning (HRMAS) nuclear magnetic resonance (NMR) spectroscopy have relied on the observation of large populations of nematodes, requiring labor-intensive sample preparation that considerably limits high-throughput characterization of C. elegans. In this work, we open new platforms for metabolic phenotyping of C. elegans mutants. We determine rich metabolic profiles (31 metabolites identified) from samples of 12 individuals using a H NMR microprobe featuring high-resolution magic-angle coil spinning (HR-MACS), a simple conversion of a standard HR-MAS probe to μHR-MAS. In addition, we characterize the metabolic variations between two different strains of C. elegans (wild-type vs slcf-1 mutant). We also acquire a NMR spectrum of a single C. elegans worm at 23.5 T. This study represents the first example of a metabolomic investigation carried out on a small number of submillimeter-size organisms, demonstrating the potential of NMR microtechnologies for metabolomics screening of small model organisms. T there are many analytical tools available for metabolomics studies, which investigate chemical pathways involving small molecules (metabolites) in biosystems such as biofluids and biopsies. Among them, H NMR spectroscopy offers a quantitative, nondestructive, and highthroughput analytical platform with minimal sample preparation and interference. Thus, NMR is widely used in metabolomics providing a robust metabolic profiling tool to discriminate samples of different biological status or origin. In particular, the use of H NMR spectroscopy has now emerged as a powerful analytical component for investigation of intact biopsies, thanks to the application of H-detected HR-MAS. This technique consists in spinning the sample rapidly at an angle of 54.74° with respect to the static magnetic field B0 to overcome magnetic field heterogeneities responsible for broad resonance lines that, in the absence of MAS, reduce the spectral information. Hence, H HR-MAS NMR is considered a near universal technique for providing unbiased and high-precision fingerprints of abundant metabolites in intact biological tissues, which has led toward a concept of real-time metabolic profiling of a surgical human biopsy in the clinical practice. In recent reports, Elena-Herrmann and co-workers have demonstrated its potential for metabotyping of intact Caenorhabditis elegans worms. These studies have paved a new platform for NMR-based metabolomics application to submillimeter-size organisms. However, since NMR is an inherently insensitive technique, HR-MAS analysis relies on large sample volume detection (typically corresponding to individual samples of more than 1000 worms). For this reason, the current HR-MAS NMR studies of C. elegans involve particularly labor-intensive sample preparation for the biologists. Meanwhile, sampling a large quantity of worms, which is necessary to record sufficient signal, implies that interindividual metabolic variability is averaged offering a global view of the metabolomics phenotype for a population of nematodes. Analysis of small numbers of worms would not only ease the sample preparation but could also allow for individual metabolic screening, opening new possibilities to characterize the phenotypic diversity within genotypes that is not achievable when working with large populations of worms. There are numerous approaches for improving NMR sensitivity that is represented by the signal-to-noise ratio SNR ∝ (1/Vnoise)[ω0(B1/i)], where vnoise is the total noise received Received: April 3, 2014 Accepted: May 22, 2014 Published: May 22, 2014 Article


e17086 Background: Use of AAB (abiraterone acetate, apalutamide or enzalutamide) has been shown to improve survival in mHSPC, but many patients are not prescribed this treatment. There is substantial interest in the broader role of SDOH in cancer. We explored how SDOH influences prescribing patterns of AAB in patients with mHSPC. Methods: Patients diagnosed with mHSPC between 1/1/2017 and 12/31/2021 were identified using the iKnowMed electronic health record database from The US Oncology Network of community oncology practices. Records were searched for prescriptions for AAB (based on intent to treat). Individual level measures were age, diagnosis year, ECOG, race and type of health insurance. Area level measures were Area Deprivation Index (ADI) at national and state level, and rural status. ADI is a validated metric based on demographic variables from census block groups; high ADI scores for state ( > 8) and national ( > 80) level are markers of low socioeconomic status. Logistic regression models were run on each SDOH variable and adjusted for confounding variables, including a joint distribution model of African American (AA) and ADI (significance at p < 0.05). Results: There were 3,855 patients identified with mHSPC: 40% had a prescription for AAB. Summary measures overall were mean age: 71 years, AA: 10%, Medicaid: 5%, ECOG 0-1 and 2+: 60% and 14% respectively; and diagnosis year 2017-21: 15%, 20%, 21%, 22%, and 21% respectively. Area level scores: National ADI high: 8%, State ADI high: 18%, rural: 5%. Interaction variable: AA + State ADI (high): 2%. Statistical differences between those with/without AAB (not shown) were diagnosis year, ECOG and age. Multivariate logistic models were adjusted for these 3 variables with the single SDOH measure as the primary independent variable and the binary variable AAB as the dependent variable (Table). Conclusions: There was no significant association between AAB prescriptions and AA race, rural status, ADI (state or national), or Medicaid status. These data indicate that SDOH measures do not appear to influence prescribing of these treatments. We believe this study is among the first to examine these particular SDOH measures and their relationship to the prescribing of oncology treatments. Further research should be conducted into the impact of SDOH measures on the fulfillment and compliance of these drugs. [Table: see text]


This paper is concerned with economic policy evaluation using the Murphy model and control theoretic principles. The approach taken here is to build a learning (or observing) model which aims to behave in the same manner for policy targets as the Murphy model to a change in policy instruments. Optimal policies are then developed through the learning model and applied concurrently to the Murphy model. The emphasis is on policy generation necessary to achieve a desired outcome and what are the implications of such policies.

Purpose: Prostate cancer (PrCa) is one of the leading causes of cancer-related deaths among men in the United States. Chemotherapy with docetaxel holds great promise and important therapeutic option for PrCa treatment. However, chemotherapy is often associated with incomplete cell death and leads to persistent senescent phenotype. Such phenotypic cancer cells survive and promotes tumor development, recurrence, and drug resistance. Altogether, targeting these cells can enhance chemotherapy outcomes. In the current study, we established a tannic acid-docetaxel scaffold nanoparticles (TDS NP) platform that allows for facile targeting and inhibition of drug induced senescence in prostate cancer. Methods: TDS NP were prepared by solvent evaporation and extrusion process using a series of tannic acid and docetaxel weight ratios. The scaffold self-assembly formation was determined using a steady-state fluorescence quenching, FT-IR, XRD, DSC, and TGA. The surface and morphological properties of TDS NPs were determined by dynamic light scattering and transmission electron microscopy. The biocompatibility assessment was characterized by hemolysis assay. C4-2 and PC-3 cell lines were used as PrCa model systems for in vitro and in vivo studies. The cellular internalization (in vitro) and accumulation (in vivo) was examined using dye-tagged TDS NPs. The superior in vitro anti-cancer and metastatic potential of TDS NPs were evaluated using proliferation, colony formation, migration, invasion, and immunoblotting assays. The anti-senescence ability of TDS NPs was examined through β-Galactosidase Staining Kit. A PC-3 xenograft mouse model was used to examine its superior therapeutic activity over free docetaxel treatment. Results: A series of physico-chemical analyses confirmed the integrity of TDS NP. An optimized formulation exhibited a spherical shape particle formulation with 124.13 ± 2.16 nm with a negative zeta potential of -14.0 mV. TDS NPs formulation exhibited superior internalization capacity in PrCa cells in a dose- and time-dependent manner. In vitro functional studies confirm superior therapeutic activity of TDS NPs over free docetaxel treatment. Enhanced pro-apoptotic while downregulating anti-apoptotic effects with treatment of TDS NPs in comparison to native drug. A profound inhibition of β-galactosidase activity was noticed with TDS NPs treatment. In vivobiodistribution studies confirm efficient accumulation of TDS NPs in mice. In addition, TDS NPs showed robust antitumor activity against PC-3 xenografts. Such improved activity was correlated with increased inhibition of senescence and induced apoptosis. Conclusion: In summary, we developed a novel tannic acid-docetaxel scaffold nanoparticle formulation that is capable of inhibiting senescence, minimizing drug resistance, and inducing apoptosis in prostate cancer.

Nowadays, two significant trends are driving the automotive industry: electric vehicles and autonomous cars. Besides the ecological aspect, electric powertrains offer attractive advantages: a fast response, a precise generation of requested torque, the possibility to have multiple motors on the vehicle. These peculiarities pave the way for reconsidering classical vehicle dynamics controls (ABS, TC, ESC) and improving autonomous driving performance. This dissertation discusses different control strategies to exploit the advantages introduced by vehicle electrification; in particular, we present a control stack for autonomous full-electric vehicles with 4 electric motors (1 per wheel). Following a bottom-up approach, we start from the lowest level, i.e. wheel dynamics, for which we have designed a nonlinear longitudinal slip regulator. The novelty of the proposed approach consists in synthesising the controller using a grey-box model to include the transmission dynamics. Afterwards, we have considered lateral vehicle dynamics, firstly to improve safety and then to increase fun-to-drive. We have proposed an ESC scheme able to maintain the vehicle stable in critical situations regardless of the road conditions; it controls a convex combination of yaw rate and sideslip. We leverage the expertise gained to design a torque vectoring control that continuously enhances the vehicle dynamics. Then, autonomous driving scenario is tackled with focus on path tracking. We propose a multi-layer controller that easily integrates the lower level control structures managing multiple actuators (steering wheel, electric motors). The controller, designed exploiting LPV/Hinf technique, includes tyre nonlinearities. Finally, the highest level, i.e. planning, is addressed; we focus on the longitudinal dynamics, in which regenerative energy capabilities can be exploited. Specifically, we have designed a progressive iterative dynamic programming algorithm that includes both comfort and consumption aspects. We have validated all the proposed control systems using the full-fledged software IPG CarMarker and VI-Grade. ABS/TC and the ESC have been experimentally tested utilising a full electric SUV with 4 motors in different conditions: dry asphalt, snow and ice. The TV has also been validated using a static simulator with certified pilots gathering useful insights that were otherwise impossible to capture.

The optical retrieval and storage technique called VisualAudio provides a way to extract sound information from an analog disk without any mechanical contact. The process is straightforward: we take a picture of each side of the disk using a dedicated analog camera, we store the film as our working copy, and when needed, we scan the film and process the image in order to extract the sound. This technique can be used to retrieve the sound from old records that are in such a bad shape that no regular turntable can be used. A working prototype has been built and has retrieved the sound from several records. We present the signal processing issues of this system and, in particular, a signal-to-noise ratio analysis.


This research examines the films Turkey's director, Emin Alper, created via the lens of the auteur concept and aims to explore common styles and inherent meanings within his creations. Initially, the auteur concept was introduced to distinguish elite directors from ordinary ones. However, it has progressed now to distinguish the directors who display technical competence, unique style, and inner meaning in their films. The role of a screenwriter is often associated with the auteur concept, given the prominence of the screenplay writing process in this theory. Emin Alper, who has directed and written four films in the last ten years, is an exceptional director whose work warrants scrutiny within the domain of auteur theory in Turkish Cinema. Throughout his films "Tepenin Ardı," "Abluka," "Kız Kardeşler," and "Kurak Günler," Alper incorporates characteristic features and internal meaning beneath the surface of the depicted events. Qualitative content analysis is utilized in this study to examine these features in Alper's films based on the auteur theory criteria. An essential aspect of auteur theory is the director's signature, namely their works' distinctive styles and themes. Distinctive styles and themes were also identified in Alper's films.


Background: Lys-63-linked ubiquitination in mitochondria occurs in PINK1/Parkin-mediated mitophagy, and its important roles have been proposed. Results: The suppression of Lys-63-linked ubiquitination did not modulate PINK1/Parkin-mediated mitophagy and Drosophila mitochondrial phenotypes. Conclusion: Lys-63-linked ubiquitination is dispensable for PINK1-Parkin pathway. Significance: This is the first study to report the biological significance of Lys-63-linked ubiquitination in PINK1-Parkin pathway in vitro and in vivo. PINK1/Parkin-mediated mitophagy is thought to ensure mitochondrial quality control in neurons as well as other cells. Upon the loss of mitochondrial membrane potential (ΔΨm), Lys-63-linked polyubiquitin chains accumulate on the mitochondrial outer membrane in a Parkin-dependent manner. However, the physiological significance of Lys-63-linked polyubiquitination during mitophagy is not fully understood. Here, we report that the suppression of Lys-63-linked polyubiquitination through the removal of Ubc13 activity essentially affects neither PINK1 activation nor the degradation of depolarized mitochondria. Moreover, the inactivation of Ubc13 did not modulate the mitochondrial phenotypes of PINK1 knockdown Drosophila. Our data indicate that the formation of Lys-63-linked polyubiquitin chains on depolarized mitochondria is not a key factor for the PINK1-Parkin pathway as was once thought.

Abstract – The purpose of this study was to use and compare four different models to estimate leaf wetness duration (LWD) on cotton leaves, using 15 min data from an automatic weather station installed inside the crop area, and also to show the differences between the LWD measured at 1.7 m in the weather station, and close to the plants. For this purpose, an automatic weather station was installed inside the crop area, where the following meteorological variables were measured at 1.7 m: air temperature and relative humidity, net radiation, wind speed, rainfall, and LWD. Six automatic micro-stations were installed at the top of the crop having sensors of air temperature, relative humidity, and LWD. These meteorological data were used to estimate LWD according to the following methods: Number of Hours with Relative Humidity above 90% (NHRH>90%); Dew Point Depression (DPD); Classification and Regression Tree model (CART); and Aerodynamic Resistance model (RES). The results showed that in general, all methods of LWD estimation performed quite well. For the DPD, CART and RES models an overestimation of around 2%, 6%, and 7% respectively was observed, whereas the NHRH>90% method showed an underestimation of 6%. This analysis resulted in high accuracy of these methods, however the precision of the estimations was not as high, remaining between 0.75 and 0.90, and resulting in mean absolute errors between 1.27 and 2 h. When only dry days were used to estimate LWD a little improvement on accuracy was observed, while for rainy days the precision decreased considerably. Comparing the LWD data obtained in the weather station with those close to the crop canopy, it was verified that a large difference existed between them, mainly for periods with less than 15 to 17 h of wetness. This shows that LWD should be measured or estimated site-specifically, or adjusted by empirical coefficients. For LWD > 17 h, normally promoted by rain, the differences are smaller both between the LWD measured/estimated in the crop and in the weather station, and among the sensors. Therefore the RES model estimated LWD at crop level with high accuracy and regular precision, and is a good option to estimate this variable without the requirement of calibration for each crop and place.


We searched spreading of an ultra-short laser impulse in the substance considering effects concerned with dipole-dipole interaction and photo-refraction. Special photo-refracting model was chosen using experiments on ferroelectric crystals. We derived an effective equation and performed solutions of soliton type. We also elaborated these solutions for transverse stability and stability with respect to higher non-linearities. We searched dependencies ofderived solutions on the problem parameters.


Several data processing methods for determining Rydberg constant in the hydrogen atom spectroscopy experiment are analyzed. The result shows that the method of linear fitting through zero point which takes wavelength as variable and the method of calculating the weighted average of Rydberg constants determined at all wavelengths are more reasonable.

A new structure that consists of two magnetically coupled planar inverted-L antennas (PILAs) is proposed for designing a miniature radio frequency identification (RFID) tag that can be used for on-metal tagging applications. The two PILAs, which act as a radiator and a coupler separately, is magnetically coupled to induce meandered currents on the radiator for achieving miniaturization. As a result, the tag size can be scaled down to $25.00 mm \times 18.75 mm \times 3.1 mm (0.0763\lambda \times 0.0572\lambda \times 0.0094\lambda)$. Despite being electrically very small and low in profile, the proposed tag can be read from beyond 8.3 m (4 W EIRP) on metal at the resonant frequency of 915 MHz. This shows that the induced meandered currents are effective for scaling down the antenna size without affecting the radiation characteristics much. The proposed method is able to introduce lumped inductance and capacitance to antenna input impedance for achieving conjugate match with the chip impedance.

Bis(2,4,6-tri-tert-butylphenyl)phosphavinylidene(oxo)phosphorane (1) (Mes* = 2,4,6-tri-tert-butylphenyl), the first 1λ5σ3,3λ3σ2-diphosphaallene, has been synthesised by addition of the phosphaalkenyllithium Mes*P=C(Li)Cl to dichlorophosphane oxide Mes*P(O)Cl2. Compound 1 is stable in the solid-state but undergoes a slow intramolecular cyclisation in solution by addition of a C–H bond of an ortho-tert-butyl group to the σ3-P=C double bond. Water adds chemoselectively and regioselectively to the λ5σ3-P=C bond, which appears to be more reactive than the λ3σ2-P=C bond. This leads to the hydrolysis compound 8 which has been structurally characterised. The new bis(phosphane oxide)methylene 9 formed from the successive cyclisation of anortho-tert-butyl group to the λ5σ3-P=C bond and addition of water to the λ3σ2-P=C bond has also been structurally characterised.

Correlated level ab initio calculations (large basis set MP2, and MP4, CCSD, and CCSD(T) computations) have been performed for 13 conformers of neutral glyane, including all 8 possible conformers with planar heavy-atom arrangements. These calculations resulted in accurate geometric structures, relative energise, harmonic vibrational frequencies, and infrared intensities for all conformers. The structural results obtained support the rotational constants measured for the two lowset-energy forms of glycine, and their high accuracy should be profitable in the search for other conformers by rotational spectroscopy

This paper investigates whether the likelihood of entrepreneurial activity is related to the competitive pressure for promotion within a firm. We argue that competitive pressure can increase the likelihood that an individual will perceive entrepreneurship as a relatively attractive outside option. We test our prediction using a comprehensive matched employer-employee longitudinal data set from Denmark. To this end, we exploit variation in the gender composition of the established firms. We find that individuals are more likely to become entrepreneurs if they start working for firms exhibiting higher levels of competitive pressure. We also find that such competitive effect is more pronounced in firms which are more entrepreneurial prominent, i.e. firms more prolific in spawning entrepreneurial ventures. This ultimately suggests that combining sources of incentives to entrepreneurship have a positive non-linear effect.


Oxo-biodegradable plastics are widely used as an alternative to well-known polyethylene and polypropylene. thanks to the polyolefin base, they have the necessary set of operating characteristics and are able to be processed with the same parameters as for example polyethylene. The presence of prooxidant in their composition ensures its oxo-destruction after the end of the product's service life with the subsequent biodegradation of the obtained material fragments. The combination of a natural filler and a pro-oxidant additive in polymer compositions makes it possible to obtain a material with a programmed life and destruction


This paper addresses, from an analytical perspective, the concept of"friendship", as methodology in Christian education, stemming from the elements of Scripture present in the Gospel. Christ uses personal example as a real, tangible, obvious and easy element, meant to challenge and support with arguments behavioural changes through modelling ( after the model of the one standing in front), , and everyone is invited to appreciate, respect and love one another. Jesus Christ is the teacher par excellence, and his methodology implies the cultivation of friendships. From a pragmatic perspective, he sees everybody as friends, regardless of the potentialities that each might have, of social status or used resources. Love as strong feeling of affection, attraction and union between people takes on more hypostases, of which the agapeis the expression of complete love, devoid of selfishness, with the the capacity to continuously offer, without asking for anything else in exchange, it is the model of Christic love; being a love of action, which implies unconditional support, compassion for the other, and is consumed as an attitude, a spiritually motivated behaviour and unrestrained in feelings.
