The message from remote library clients is clear and unequivocal - they want material quickly and easily. They would prefer not to have to differentiate between the three
library services of intercampus, interlibrary, or off-campus requests - they just want a particular document or book forwarded to them as soon as possible. At the University of Southern Queensland Library, VDX software has been utilised to provide a single search and request interface for library material. Differentiating between individual clients,it displays and activates only those services for which a particular client is eligible. Remote undergraduates for example, have the ability to search and request from USQ catalogue only, while those students eligible for interlibrary loans can search and initiate requests across a range of catalogues. Whilst simplifying processes for clients, the challenge to Library staff has been to successfully manipulate the software and work processes to handle this complex arrangement. This paper will discuss the introduction of this new initiative focusing on the following issues: - Background - Client view - Dual services and associated challenges - Impact on staff - Improvements planned in the next six months - Marketing - Conclusion


A method for the accurate numerical prediction of the tip vortices shed from hydofoils The possibly accurate numerical prediction of the detailed structure of vortices shed from the tips of hydrofoils is an important element of the design process of marine propellers. The concentrated tip vortices are responsible for the propeller cavitation erosion and acoustic emission. The purpose of the project described in this paper was to develop the numerical method for prediction of the tip vortex structure. In the course of the project the numerical calculations were confronted with the results of experimental measurements. This led to creation of the specific method of construction of the computational grid and to selection of the optimum turbulence model. As a result the reliable method for the accurate numerical prediction of the concentrated tip vortices for different hydrofoil geometry and flow conditions has been developed and validated. This method enables elimination of the unfavourable phenomena related to the tip vortices in the course of the propeller design calculations.


Transition state theory forms the basis of computing reaction rates in chemical and other systems. Recently, it has been shown how transition state theory can rigorously be realized in phase space by using an explicit algorithm. The quantization has been demonstrated to lead to an efficient procedure to compute cumulative reaction probabilities and the associated Gamov-Siegert resonances. In this paper, these results are used to express the cumulative reaction probability as an absolutely convergent sum over periodic orbits contained in the transition state.


Measurements of the structure factor S (k) for /sup 4/He at constant density above and below T/sub lambda/. The results show a clear loss of spatial order on cooling through T/sub lambda/. Application of the theory of Cummings, Hyland, and Rowlands to the data allows a measurement of the condensate fraction for He II.


Abstract A banking system is functional when it expands the potential to provide more liquidity to the economy, especially for development finance. The advances of Information and Communication Technology (ICT) can contribute to increasing banks' potential to offer more products and services, expanding their capacity to be more functional. Diversifying financial instruments can encourage them to operate with more profitable operations in the short term to the detriment of the supply of credit in the long term, decreasing their ability to be more functional. This article aims to analyze the relationship between ICT and the functionality of Brazilian banks between 1995 and 2016. We created an index of functionality. The Panel Data estimation verified an ambiguous impact of ICT on banks' functionality. The use of electronic devices and services for software-driven data processing and transmission has had a positive effect on this index. However, the influence of ICT on functionality was to enhance the negative effects of financial innovations on the supply of credit by banks because of the agents" incentives to invest in short-term and more liquid assets, vis à vis of financing long-term investments, harming the capacity for financing Brazilian development.


For a cuspidal automorphic representation of GL2/Q associated to a modular form, the local and global Langlands correspondences are compatible at all finite places of Q. On the p-adic Coleman-Mazur eigencurve this principle can fail (away from p) under one of two conditions: on a generically principal series component where monodromy vanishes; or on a generically special component where the ratio of the Satake parameters degenerates. We prove, under mild restrictive hypotheses, that such points are the intersection of generically principal series and special components. This is a geometric analogue of Ribet's level raising and lowering theorems.


The initial complaint of a 79-year-old woman was of mild headache, neck pain, and sore throat. She had a history of hypertension, diabetes mellitus, and heavy cigarette smoking. Examination by an otolaryngologist, which included laryngoscopy, revealed no abnormalities. Three weeks later, the patient's throat and neck pain became more severe. She had no arthralgias, visual loss, fever, or worsening head pain.


− District heating was first introduced in Korea in 1985. As the service life of the underground thermal piping network has increased for more than 30 years, the maintenance of the underground thermal pipe has become an important issue. A variety of complex technologies are required for periodic inspection and operation management for the maintenance of the aged thermal piping network. Especially, it is required to develop a model that can be used for decision making in order to derive optimal maintenance and replacement point from the economic viewpoint in the field.

Eng. Res., Vol. 55, No. 3, June, 2017 In this study, the analysis was carried out based on the repair history and accident data at the operation of the thermal pipe network of five districts in the Korea District Heating Corporation. A failure probability model was developed by introducing statistical techniques of qualitative analysis and binomial logistic regression analysis. As a result of qualitative analysis of maintenance history and accident data, the most important cause of pipeline damage was construction erosion, corrosion of pipe and bad material accounted for about 82%. In the statistical model analysis, by setting the separation point of the classification to 0.25, the accuracy of the thermal pipe breakage and non-breakage classification improved to 73.5%. In order to establish the failure probability model, the fitness of the model was verified through the Hosmer and Lemeshow test, the independent test of the independent variables, and the Chi-Square test of the model. According to the results of analysis of the risk of thermal pipe network damage, the highest probability of failure was analyzed as the thermal pipeline constructed by the F construction company in the reducer pipe of less than 250mm, which is more than 10 years on the Seoul area motorway in winter. The results of this study can be used to prioritize maintenance, preventive inspection, and replacement of thermal piping systems. In addition, it will be possible to reduce the frequency of thermal pipeline damage and to use it more aggressively to manage thermal piping network by establishing and coping with accident prevention plan in advance such as inspection and maintenance.


The development of paclitaxel-loaded polymeric nanoparticles for the treatment of brain tumors was investigated. Poly(lactide-glycolide) (PLGA) nanoparticles containing 10% w/w paclitaxel with a particle size of 216 nm were administered through intranasal and intravenous routes to male Sprague–Dawley rats at a dose of 5 mg/kg. Both routes of administration showed appreciable accumulation of paclitaxel in brain tissue, liver, and kidney without any sign of toxicity. The anti-proliferative effect of the nanoparticles on glioblastoma tumor cells was comparable to that of free paclitaxel.


This paper proposes a guarantee steady state observation precision and pole assignment precision of the feedback controller, the basic idea is to introduce state observer can easily get dc linear motor speed and acceleration condition, state space pole assignment can pass, select the appropriate zero pole can improve the control performance of the motor. Based on the observation of the gain matrix can compensate for the steady-state error of the dc linear motor. Based on the observation of the gain matrix can compensate for the steady-state error of the dc linear motor. Matlab simulation results show that the control algorithm is compared with the traditional pole assignment, it is able to quickly and accurately follow the speed of the motor. The system has better dynamic and steady-state performance, and its characteristic of the closed-loop system robustness is stronger.


In previous work, it was established that at high specific impulse operation, plasma acceleration is confined to a small region at the upstream end of the accelerator. Such rapid axial acceleration must be accompanied by viscous losses arising from normal viscous stresses. This effect is studied by including viscous terms in the momentum equation. The resulting higher order formulation is solved by a combination of analytical and numerical methods. Results show that this effect alone can reduce accelerator efficiency by 5% and thrust and specific impulse by about 22%. Accurate knowledge of plasma viscosity values in the accelerator is necessary for computational design. In the regime of high specific impulse operation, accelerator efficiency is strongly influenced by the Reynolds number of the plasma flow.

Virgins (homozygous bw or st) were collected over a period of about a week and stored on culture medium composed of sugar, agar, and water. When the youngest females were at least two days old, they were mated for one day to males homozygous for st or bw, respectively; the males were then discarded and the females irradiated. After irradiation the females were placed in bottles containing a standard nutrient medium that included agar, cornmeal, molasses, brewer's yeast, and water. Parents were shaken into fresh bottles every four days, furnishing a total of four broods of offspring. The X-ray machine was operated at 200 kvp and 20 ma with 1 mm aluminum filtration. The total dosage of approximately 3360r was given at about 1920r/min either continuously (in 1 min 45 sec) or interruptedly in seven 15-second irradiations given 8 minutes apart (requiring a total time of 49 min 45 sec). The same kind of continuous treatment was given also to some bw or st virgins which were subsequently mated to the appropriate type of untreated male. F, males were individually crossed to homozygous bw st virgins. Since the mutants bw and st are located on the second and third chromosomes, respectively, the F, progeny can be scored (or further tested) to determine the presence in the F, male of a heterozygous reciprocal translocation between chromosomes 2 and 3. The temperature was approximately 25 + 1 "C throughout.

Submarine topography, bottom sediments, horizontal and vertical temperature and salinity structure, characteristics also origin and movement of water masses, currents, and ice conditions are briefly described.


A palatal wound becomes when palatal premolar region is used for obtaining connective tissue graft. To overcome this disadvantage, connective tissue graft is obtained from interdental papilla; as a result, there is no palatal wound. Envelope flap has blood supply by both sides because it contains no vertical incisions. Therefore, the purpose of this case report was to evaluate the free reverse rotated papillary connective tissue graft (CTG) and coronally advanced envelope flap (CAEF) technique for the treatment of gingival recession. A patient with the gingival recession of 5 mm depth and 3 mm width was treated by free reverse rotated papillary CTG and CAEF technique. A partial-thickness envelope flap was made on the underlying alveolar mucosa. The recipient bed was prepared by de-epithelialization of adjacent papillae to gingival recession. The donor papilla was de-epithelialized on facial aspect, and CTG was harvested. The papillary CTG was then placed on recipient bed in a reverse manner that is base toward cementoenamel junction and the tip toward the base of gingival recession and sutured. The envelope flap was coronally advanced to fully cover the papillary CTG and sutured. After 1 year, 100% root coverage obtained. The histologic studies will be required to confirm the type of attachment obtained by free reverse rotated papillary CTG and CAEF technique on the root surface.


The muon radiography technique is part of the straight-ray scanning imaging methods and it is usually employed to produce two-dimensional images of the integrated density in the radial direction from the detector position. However, in the literature there are already some examples of muon tomographies made by combining several measurements from different observation points. The work presented in this article fits into this line of research: a tomography of a target composed of lead blocks arranged in a non-trivial geometry was carried out by means of muon absorption radiography measurements. To solve the inversion problem, an iterative algorithm called SART was employed, obtaining better results than using a Chi-squared minimization.


Silver(I) and palladium(II) complexes of constrained-geometry chiral di-N-heterocyclic carbenes have been prepared from trans-1,2-diaminocyclohexane via the base-induced 1,3-cycloaddition of tosylmethyl isocyanide to diimines.


Random linear codes are a workhorse in coding theory, and are used to show the existence of codes with the best known or even near-optimal trade-offs in many noise models. However, they have little structure besides linearity, and are not amenable to tractable error-correction algorithms. In this work, we prove a general derandomization result applicable to random linear codes. Namely, in settings where the coding-theoretic property of interest is "local" (in the sense of forbidding certain bad configurations involving few vectors–code distance and list-decodability being notable examples), one can replace random linear codes (RLCs) with a significantly derandomized variant with essentially no loss in parameters. Specifically, instead of randomly sampling coordinates of the (long) Hadamard code (which is an equivalent way to describe RLCs), one can randomly sample coordinates of any code with low bias. Over large alphabets, the low bias requirement can be weakened to just large distance. Furthermore, large distance suffices even with a small alphabet in order to match the current best known bounds for RLC list-decodability. In particular, by virtue of our result, all current (and future) achievability bounds for list-decodability of random linear codes extend automatically to random puncturings of any low-bias (or large alphabet) "mother" code. We also show that our punctured codes emulate the behavior of RLCs on stochastic channels, thus giving a derandomization of RLCs in the context of achieving Shannon capacity as well. Thus, we have a randomness-efficient way to sample codes achieving capacity in both worst-case and stochastic settings that can further inherit algebraic or other algorithmically useful structural properties of the mother code.

[Objective] To study the preparation and purification method of protoplast from Nervilia fordii(Hance) Schltr.leaves.[Method] Taking the yield and survival rate of protoplast as index,the effects of different factors such as pretreatment,enzymolysis method,enzymolysis temperature,rotate speed of centrifugation,illumination,and sieve mesh number on the separation and purification of protoplast from N.fordii leaves were studied.[Result] The optimum process for protoplast isolation was obtained as follows: N.fordii leaves were first pretreated for 1 h in CPW solution containing 13% mannitol,and then incubated at(25±1)℃ in enzyme solution under dark conditions;after the enzymolysis,the enzyme liquid was filtrated through 200 mesh screen and centrifuged for 8 min at the speed of 800 r/min.Repeat the filtration and centrifugation once before microscopic examination.Under the above conditions,a large amount of complete and clear protoplast with few cell debris was obtained.[Conclusion] The preparation system has been successfully established and laid a good foundation for establishing protoplast regeneration system from N.fordii leaves.


Boceprevir is a NS3/4A hepatitis C virus (HCV) protease inhibitor, used in combination with peginterferon and ribavirin to treat HCV. Boceprevir undergoes extensive metabolism via cytochrome P450-mediated oxidation and ketoreduction by cytosolic aldo-keto reductases. Amlodipine has been used for the treatment of patients with hypertension and also metabolised through cytochrome P450 pathway. Here, we presented a case of boceprevir and amlodipine interaction in a patient with chronic HCV and her echocardiography and electrocardiographic follow-up results.

Two 5,5′-bitetracene derivatives were synthesized from tetracenone in three steps as novel axially chiral biaryls. The enantiomers of 12,12′-bis(phenylethynyl) derivative were successfully resolved by chiral HPLC. Their absolute stereochemistry was determined by theoretical calculations of the CD spectra using the time-dependent (TD) DFT method.


The effect of silica fume in concrete improves both the mechanical and durability characteristics of the concrete. The paper aims to review the effect of silica fume on properties of concrete. The replacement of silica‐fume as partial replacement of cement by weight at 0% (control mix), 5%, 10%, 15%, 20%, and 25%, with and without superplasticizer are studied. It emphasized the effect of silica fume on workability level and its maintenance of fresh concrete; strength development, strength optimization and elastic modulus of hardened concrete; and chemical and mechanical durability of mortar. The chemical and physical properties of silica fume shows that it is most reactive pozzolan. Concrete containing silica fume can have very high strength and can be very durable.


This paper presents a suit of igneous rocks in the SN-trending geological section with a length of about 200km from Chifeng (Inner Mongolia) to Lingyuan (western Liaoning Province), to explore the Early Mesozoic geological evolution of the northern margin of North China Craton. The Early Mesozoic (237~206Ma) igneous rocks occur as dyke swarm, diorite, alkali granite, alkali complex, mafic granulite, cumulate and its mantle enclaves that were derived from distinct depths. It is concluded that the lithospheric mantle beneath North China initially strongly interacted with and enriched by crustal materials and that magma underplating induced rapid differential uplift and denudation of continental crust, associated with accretion of the Mesozoic crust and adjustment of the lithospheric structure.

Residential-scale photovoltaic (PV) inverters available in the market are embedded with two key functions designed to help mitigating voltage rise issues: Volt-Watt and Volt-var. Volt-var has attracted significant attention as it does not involve generation curtailment. However, residential-scale PV inverters are sized (kVA) to meet the peak active power generation of the panels (kW). Since active power generation is typically prioritized, their capabilities to absorb reactive power (kvar) during high generation periods will be limited. Using a real UK LV network, this work provides a comprehensive analysis to understand the extent to which the adoption of Volt-var control helps managing voltage rise issues. Considering different Volt-var curves and PV penetrations, results demonstrate that Volt-var control is ineffective when reactive power is needed the most. Furthermore, reactive power increases currents and, therefore, asset utilization. This highlights the importance of considering the kVA rating of inverters when adopting solutions involving reactive power.


The temporal variations (diurnal and annual) in arboreal (εTree) and bare soil (εSoil) dielectric constants and their correlation with precipitation were examined for several trees in Japan. A significant (1 σ (standard deviation) and 2 σ) εTree increase is observed after rainfall at 89.8% and 90.5% probability. However, rainfall does not always induce significant εTree increases. Rainfall of more than 5 mm/day can induce 1 σ εTree Tree increase at a 59.6% probability. In order to examine whether the increase in εTree affects the L-band σ0 variation in a forest, the four-year temporal variation of the L-band backscattering coefficient (σ0) was estimated from observations by the Advanced Land Observing Satellite Phased Array type L-band Synthetic Aperture Radar. Observed maximum absolute deviations from the mean over the forest area were 1.0 and 1.2 dB for σHH0 and σHV0, respectively, and 4.0 and 3.0 dB over open land. σ0 and rainfall correlations show that εTree and σForest0 are proportional to precipitation integrated over seven or eight days; εSoil and σOpen land0 are proportional to precipitation integrated over three days. This finding indicates that εTree variations influence σForest areas0. A stronger correlation between σHV0 and precipitation is observed in several sites with low σHV0, where less biomass is expected, and several sites with high σHV0, where more biomass is expected. A weaker correlation between σHV0 and precipitation is observed for several sites with high σHV0. These differences may be explained by the different contributions of double bounce scattering and potential transpiration, which is a measure of the ability of the atmosphere to remove water from the surface through the processes of transpiration. The two other results were as follows: 1) The functional relation between aboveground biomass and σ0 showed dependence on precipitation data, this being an effect connected with seasonal changes of the εTree. This experiment reinforces the fact that the dry season is preferable for retrieval of woody biomass from inversion of the functional dependence of SAR backscatter and for avoiding the influence of rainfall. 2) The complex dielectric constant for a tree trunk, which is measured between 0.2 and 6 GHz, indicates that free water is dominant in the measured tree.


The sampling and analysis of the radioactive liquid wastes and sludges in the Melton Valley Storage Tanks (MVSTs), as well as two of the evaporator service facility storage tanks at ORNL, are described. Aqueous samples of the supernatant liquid and composite samples of the sludges were analyzed for major constituents, radionuclides, total organic carbon, and metals listed as hazardous under the Resource Conservation and Recovery Act (RCRA). Liquid samples from five tanks and sludge samples from three tanks were analyzed for organic compounds on the Environmental Protection Agency (EPA) Target Compound List. Estimates were made of the inventory of liquid and sludge phases in the tanks. Descriptions of the sampling and analytical activities and tabulations of the results are included. The report provides data in support of the design of the proposed Waste Handling and Packaging Plant, the Liquid Low-Level Waste Solidification Project, and research and development activities (R D) activities in developing waste management alternatives. 7 refs., 8 figs., 16 tabs.


The objective of this research is to investigate the effect of parental style and family income on children's involvement in family purchasing decision. Using dyadic method, the samples of this research consist of 43 parent (fathers or mothers) and 43 children whose ranged 11-16 years old as respondent. The result of this research shows that parental style, with its four dimensions (authoritative, authoritarian, indulgent and neglecting), has no significant difference on children's involvement in family purchasing decision. Another result in this research shows that family income difference does not influence the children's involvement level in family purchasing decision. The last, it is also indicated that children using bilateral strategy have a higher signification of influence than those who use unilateral strategy.


A general finite-difference method for solving the three-dimensional turbulent boundary-layer equations for the flow around ship hulls is presented. The numerical method allows for reversal of the girthwise flow direction. A non-orthogonal, easy-to-use co-ordinate system was applied. The pressure distribution was determined for potential flow computed by means of Webster's panel method. results are presented for the so-called HSVA-Tanker model (scale: 1/95) and for the corresponding full-scale ship. Calculated model results are compared with experimental data measured by Hoffmann (1976) and by Knaack (1992).


Schizophrenia is a disorder commonly treated with monotherapy-antipsychotic medications. Despite this treatment, 30% of persons suffering this disorder will still experience symptoms that severely impact their quality of life and functional ability (Temmingh & Stein, 2015). These symptoms can also be associated with increased depression, suicidality, medical service utilization, and cognitive impairment. Treating the symptoms of schizophrenia is an important and often neglected aspect in the management of this mental disorder. To address this, various other drugs are often added to the antipsychotic medication of patients to reduce the symptoms and provide a better quality of life, including functional capacity (Jablensky et al., 2017). One of the drugs utilised to treat the symptoms of schizophrenia is Valproate. Also used in the treatment of epilepsy, Valproate is frequently utilised to stabilise the mood of those suffering this mental disorder.


Radiation therapists implemented telephone follow‐up (TFU) in 2015 as an additional point of care post‐treatment. The purpose of this study was to determine whether TFU identified patients who required additional post‐treatment care before the next scheduled review.


The equilibrium freezing point for body fluids of hatchling Blanding's turtles (Emy- doidea blandingii) is near -0.7 C, but neonates that are held in a dry, ice-free environment can be (super)cooled to approximately -6 C before they begin to freeze spontaneously (i.e., by heteroge- neous nucleation). Unfrozen turtles recover from exposure to -4 C, so the limit of supercooling (-6 C) probably approximates their limit of cold-tolerance. When hatchlings come into contact with ice in frozen soil, however, ice crystals penetrate the integument and cause body fluids to freeze at temperatures only slightly below the equilibrium freezing point. Freezing is fatal except at temper- atures above -2.5 C. Temperatures in the soil are likely to go below -2.5 C during winter, so the risk of freezing and dying affords an explanation for why hatchling Blanding's turtles seldom over- winter in the natal nest.


In mining process, the height of water flowing fractured zone is important significance to prevent mine of water and gas, in order to further research the failure characteristic of the overlying strata. Taking certain coal mine with 5.82 m mining height as the experimental face, by using the equipment which is sealed two ends by capsules in borehole, affused measurable water between the two capsules and borehole televiewer system, ground penetrating radar, microseismic monitoring system in underground coal mine, the height of water flowing fractured zone of fully-mechanized top caving are monitored, a numerical simulation experiment on the failure process was conducted, a similarity simulation experiment on the cracks evolution was conducted, at the same time, empirical formula of traditional was modified, The results showed that the height of caving and fractured zones were respectively 43.1 and 86.7 m in fully mechanized sub-level caving mining. The data difference of each test method of caving, fractured and water flowing fractured zones were respectively less than 4.5%, 7.1% and 9.0%. The degree of fracture development was low before mining, the number of fissures was obviously increased after mining, the degree of fracture development increased. The fractures cluster region mainly focuses near the coal wall. The fractures density distribution curves of overlying strata like sanke-shapes. The new and adapt to certain coal mine geological conditions empirical formula of water flowing fractured zone height is proposed.

A total of seven Pyrazolones and Pyridines and three Schiff bases were evaluated in-vitro against Alternaria brassicae Causative organism of black leaf spot disease among crucifers. Pyrazolone, Pyridine and Schiff bases (C1-C10) are tested in-vitro. All ten novel synthetic compounds designated C1 to C10 did not show antifungal activity against Alternaria brassicae.


The interaction between sodium poly(styrene sulfonate) (NaSS) and side-chain charged polycation polymer (pendent type) or main-chain charged polycation polymer (integral type) has been studied. It was found that the polyion complex (the reaction product of these polyelectrolytes) of pendent–pendent type has an equimolar composition at any mixing ratio of two component polymers. However, a polyion complex of integral–pendent type can form a water-soluble complex with a ratio of [polycation]/[polyanion] = 1/3, in addition to a complex with a equimolar composition. The mechanism of formation of this specific complex is discussed.


As data-based decision making is receiving increased attention in education, more and more school performance feedback systems (SPFSs) are being developed and used worldwide. These systems provide schools with data on their functioning. However, little research is available on the characteristics of the different SPFSs. Therefore, this study reflects on the characteristics of SPFSs to provide feedback designers and users arguments for making sound choices in selecting SPFSs with particular characteristics. The results of our study show that the 5 SPFSs selected for the purpose of comparison differ with respect to features related to data gathering and data analysis processes, the content, and the numerical measures and representation modes used. A wide variety can be detected in terms of the complexity and accuracy of data modeling. Users need to be properly informed about the underlying rationale for the features of each SPFS, and on the limitations and strengths of the performance indicators used.


The objective of this scoping review is to determine to what extent the recommendations on perinatal care protect breastfeeding during the COVID-19 pandemic. The review follows the PRISMA ScR Extension guidelines. The research was conducted in Scopus, Medline via Pubmed, and Web of Science databases from 1 March 2020 to 31 May 2021, using 392 combinations of keywords. We searched for reviews and original papers published in English providing recommendations on delivery mode, companion during labor, the possibility of skin-to-skin contact (SSC), breastfeeding, and visitors policy. After screening, 86 out of 8416 publications qualified for data extraction. The majority of them indicated that COVID-19 infection is not a sufficient reason for a cesarean section; however, on a national level, cesarean births in severely ill patients were overrepresented. A significant number of recommendations deprived mothers of the necessary support during their labor and stay in the maternity ward. A shared decision-making model was hardly visible. Only the earliest COVID-19 recommendations suspended direct breastfeeding; in later publications, decisions were related to the mother's health, but other options of natural feeding were rarely discussed.


We construct Quillen type spectral sequences in homology and rational homotopy for coobration sequences which are Eckmann-Hilton dual to analogous ones for bration sequences. These spectral sequences are constructed by direct ltrations of the Adams cobar construction. We also prove various collapsing theorems generalizing results of Clark and Smith in the case of a wedge of 1-connected nicely pointed spaces. 1. Introduction The purpose of this paper is to study the relation between the rational homotopy groups of topological spaces in coobration sequences. In his pathbreaking paper on rational homotopy theory Quillen derives a Lie algebra spectral sequence relating the rational homotopy Lie algbras of spaces in a coobration. This spectral sequence is a perfect Eckmann-Hilton dual to the coalgebra spectral sequence of Serre relating the rational homology coalgebras of spaces in a bration. 13] Quillens approach is via homotopical algebra viewing rational ho-motopy theory in terms of both equivalent homotopy theories of the closed model categories of diierential graded Lie algebras and diier-ential graded coalgebras. Instead of using models we construct the Quillen spectral sequence by deening an appropriate ltration of the cobar construction functor and use a theorem of Adams, which gives an isomorphism between the homology of the loops of a space and the homology of the cobar construction applied to the normalized chain complex on the space, explicitely we have an isomorphism of graded connected k-algebras 1]

The occurrence of the Asiatic string cottony scale Takahashia japonica Cockerell (Hemiptera, Coccomorpha, Coccidae) in Europe is reported. The string cottony scale was collected on branches of different trees (Acer pseudoplatanus L., Albizia julibrissin Durrazz, Carpinus betulus L., Celtis australis L., Liquidambar styraciflua L. and Morus nigra L.) growing in parks, parking lots and along tree-lined streets located in the provinces of Milano and Varese (Northern Italy).


Neural networks based on the physical characteristics of an object have been actively used in recent time in order to solve combined problems that require multi-step calculations. Therefore this technology shall be thoroughly studied and properly used. Neural networks solve many problems in different fields of science. Today there are several different ways of application, one of the possible applications is the solution of the equation of partial variables, in special cases the approximation of piecewise functional systems can be used. This article presents an overview of neural network architecture based on physical characteristics of the object. The application of physical informative neural networks (PINNs) for approximation of piecewise functional systems is considered. It is shown that PINNs allow to use information about the physical equations of the system in training, automatically determine boundaries between ranges of input variables, and use various activation functions and hidden layers.


Introduction: The incidence of pain in the craniomandibular region has grown exponentially in recent years. Patients with this condition often relate other associated dysfunctions not only manifest in the dental, jaw and musculoskeletal structures; but also aoect cognitive and psychosocial domains. The dipculty of diagnosis and treatment of this pathology is due to their global and local mechanical complexity and at the multifactorial component of his etiology. Methods: We conducted a literature search in various scientiqc data bases. Search terms in English were: "etiological factors of temporomandibular joint disorders", "chronic pain" and "biopsychosocial pain". Search terms in spanish were: "investigación cualitativa en qsioterapia, dolor crónico y disfunción témporomandibular". Results: Key concepts found in the literature reviewed in relation to the understanding of the etiologic factors of temporomandibulars disorders [TMD] are summarized. Biomedical and psychological models have limitations in this regard. Byopsicosocial concepts allow a more holistic view of the etiologic factors of temporomandibular disorders. Discussion: The concept of psychophysical unity defended by Damasio A. (1) interacts with the biopsychosocial model of pain and temporomandibular dysfunction. The integrated and multidimensional approach to physical, psychological and psychosocial factors should have therapeutic applicability of the concepts of the TMD, which may be used by various health professionals involved in the multidisciplinary treatment of these patients. Conclusion: Future research should raise a more rigorous methodology, based on scientiqc evidence. The qualitative research methodology in physical therapy may allow better understanding of the suoering experienced by patients with chronic jaw problems and redirect treatment guidelines.

The inductive database vision (knowledge discovery as an extended querying process) has been suggested as a candidate formal framework for data mining. It has been studied as such within the EU funded cInQ IST-FET project (2001-2004) and it is now considered within the follow-up IQ IST-FET project (2005-2008).

During this talk, we will survey the major results obtained within these projects so far. More precisely, we will consider our own practice of gene expression data analysis by means of data mining techniques (joint work with Celine Robardet, Jeremy Besson, Ruggero Pensa and Ieva Mitasiunaite). We will show that many interesting processes can be based on inductive queries which declaratively specify constraints on desired patterns (set patterns from 0/1 data encoding expression properties of genes in given samples, sequential patterns from ordered data like gene promoter sequences, global patterns like bi-partitions in gene expression data sets, etc).

Supporting such processes needs for efficient solvers and we will illustrate how the targeted applications have given rise to nice scientific and technical problems, some of them solved, many others still open. The considered technical issues will concern our recent results w.r.t. constraint-based mining for bi-sets, fault-tolerant local pattern mining or constraint-based mining of bi-partitions.


Accurate estimates of species relationships are integral to our understanding of evolution, yet many relationships remain controversial despite whole-genome sequence data. These controversies are due in part to complex patterns of phylogenetic and non-phylogenetic signal coming from regions of the genome experiencing distinct evolutionary forces, which can be difficult to disentangle. Here we profile the amounts and proportions of phylogenetic and non-phylogenetic signal derived from loci spread across mammalian genomes. We identified orthologous sequences from primates, rodents, and pecora, annotated sites as one or more of nine locus types (e.g. coding, intronic, intergenic), and profiled the phylogenetic information contained within locus types across evolutionary timescales associated with each clade. In all cases, non-coding loci provided more overall signal and a higher proportion of phylogenetic signal compared to coding loci. This suggests potential benefits of shifting away from primarily targeting genes or coding regions for phylogenetic studies, particularly in this era of accessible whole genome sequence data. In contrast to long-held assumptions about the phylogenetic utility of more variable genomic regions, most locus types provided relatively consistent phylogenetic information across timescales, although we find evidence that coding and intronic regions may, respectively and to a limited degree, inform disproportionately about older and younger splits. As part of this work we also validate the SISRS pipeline as an annotation-free ortholog discovery pipeline capable of identifying millions of phylogenetically informative sites directly from raw sequencing reads.

New media era brought a complex story about what is media audience nowadays. The situasion in this postmodernism world is quite different because audience has become more active in consuming the new media. The one that once known as mass audience has now dissapeared because of the popularity of the new media. When audience is no longer a mass, fandom emerge as one of the most known as the new media audience.


Abstract Salinity and moisture stress are main limiting factors of agricultural development on arid and semi‐arid lands. The objective of this study was to evaluate the tolerance of sesame (Sesamun indicum L.) genotypes to salinity. Salinity treatments in rooting media were 0.5, 2.0, 3.5, 5.0, and 7.0 dS m−1 using calcium chloride (CaCl2). Germination of 50 genotypes was evaluated. Twenty seeds of each cultivar were set in paper towels and moistened with the saline solutions for 15 days. Five germination‐selected genotypes were seeded in 10‐kg pots, and soil salinity was adjusted to the same treatments. Highly significant effects were found for dry matter at 45 (DM 45) days after planting (DAP), at 90 DAP (DM 90), and leaf area (LA). Growth differences among genotypes were only observed for DM 90. These data suggest that sesame tolerance to CaCl2 salinity improved through the growing season and may be genetically controlled.


Ableism often prevents college students from disclosing their disabilities. This practice brief, co-authored by a non-disabled faculty member and a disabled disability services professional, explores implications of crip theory to create campus cultures that foster self-disclosure of disabilities. Using tenets of crip theory–compulsory able-bodiedness, cripistemology, and disability as a fluid identity–we explore three practice issues: (a) wrestling with the murkiness in disability services professionals' decisions about who is disabled and meets accommodation eligibility requirements; (b) interrogating ableist practices of disability services offices that prevent disclosure (a reflection not on disability services but on the insidious nature of ableism); and (c) creating cultures in the classroom and co-curriculum that value disabled students' insights rather than perceive them as tragic burdens. For each issue, we explore practical implications of crip theory to encourage disclosure and allow disabled students to bring more of their authentic selves to their college experience.


The dispersion of particles in a plane mixing layer between two air streams is investigated using experimental and numerical techniques. The results show that large-scale spanwise vortices strongly influence the particle dispersion process. Particles with aerodynamic response times on the order of the large scale vortex time scales are found to concentrate near the outer edges of the vortex structures. Time average velocity measurements also demonstrate that these particles tend to move away from the center of the mixing layer


ABSTRACT:  The remarkable Muslim role in promoting the universal human culture owes to their deep affiliation with knowledge, especially, the scientific one. They availed the old as well as the contemporary civilizations to seek knowledge of all kinds. Consequently, science, technology and the other advanced disciplines developed in the Muslim World. They rendered considerable services in developing the Greek scientific ideology and contributed a lot towards its development. The Muslims handed over these valuable disciplines to the other nations especially to Europe. The modern European civilization owes greatly to the Muslim World for its scientific and technological progress. Europe utilized these priceless disciplines and made a quick journey from the hell of ignorance towards the heaven of knowledge. A particular group of orientalists has been trying to deny the glorious scientific services of the Muslims. They propagate that the Muslims have not played any considerable role in this specific area of knowledge. It is the dire need of the hour to have a meaningful analysis of the philosophy and approach of the Orientalists. This, particular, article has been composed, especially, to fulfill the educational and analytical needs of the present world.


We study an initial-boundary value problem for the nonlinear Schrödinger equation, a simple mathematical model for the interaction between electromagnetic waves and a plasma layer. We prove a global existence and uniqueness theorem and establish a Galerkin method for solving numerically the problem.


Attention is focussed on a type of strategic alliance of the container shipping industry: vessel sharing agreements. In such consortia carriers jointly provide—but independently sell—a liner service. The strategic alliances studied in this work have not been extensively analyzed in the theoretical literature; a new model is proposed that embodies their main distinguishing features. By it, an examination is provided of the effects on equilibrium prices, equilibrium aggregate quantities and consumer welfare of the formation and enlargement of vessel sharing agreements. A positive answer is developed to the question raised in the title of the present work that supports a laissez-faire policy for these consortia.


The structure mentioned in this paper is consisted of thin retaining wall,anchored steel,foundation and filling soil and there is a complicated forced state inside the structure.Because of the request of drainage,a box culvert is set inside.In order to understand the mechanics feature of the box culvert inside this special structure,in this paper,the finite element method is applied to the 3D numerical calculation of the box culvert in a new type supporting structure of highway embankment and the changing regulation of settlement and the distribution regulation of inner stress are analyzed in the box culvert.


: Spinal cord injury (SCI) is often a life-changing injury requiring timely and specialised care. Significant variability in the factors affecting patient outcomes along with a relatively small number of cases present a challenge to developing effective care policies. The aim of this investigation is to identify timely and appropriate care for patients, improve access to and efficiency of specialist care services. Spinal cord injury refers to persistent damage to neural tissue and disruption of transmission along the nerves and can have profound effects on patients' quality of life. Timely and direct admission to specialised care is associated with better neurological outcomes, lower complication rates, and reduced length of stay (Parent et al. 2011). Further, specialist rehabilitation has been shown to be cost-efficient and relieving pressure in the acute care services. In NSW, services for people with SCI are delivered by a variety of specialists and generalists. Provision of care for adults with a SCI is centred at two specialist acute units and a specialist rehabilitation unit. There are 28 specialist acute adult beds and 46 specialist adult rehabilitation beds. For admission to a specialist SCI service in NSW, a person must have a persistent SCI resulting from either a traumatic injury or a non-progressive disease. Despite the recommendations, there is no central triage and allocation process or criteria to optimise allocative efficiency of SCI specialist resources. As a result, some of complex patients who could have benefited from specialist care do not get access to it in a timely manner. A discrete-event dynamic simulation model (DSM) was developed by a participatory co-design approach. A series of workshops were conducted in 2022 incorporating clinicians, managers, and health executives to map current SCI pathways and processes and to identify and use existing data sources to understand the performance of these pathways including the identification of delays and gaps in care delivered against the evidence base. The data sources used in the SCI DSM were clinical registry data (estimating case mix), hospital admission data (current patients' journey), occupancy data (bed utilization and treatment time and delays) and expert knowledge (triage criteria)


Once return of spontaneous circulation (ROSC) is achieved in cardiac arrest (CA) patients (pts), guidelines recommend immediate acquisition of a 12-lead electrocardiogram (ECG) in order to try to identify those with underlying ischemic heart disease that would benefit from an emergent coronary angiography. Nevertheless, post-ROSC ECG findings may be influenced by factors such as drugs used during CPR (e.g., adrenaline) or metabolic state of pts (e.g., lactic acidosis) and therefore its diagnostic value for identification acute coronary lesions has not yet been established.

 To describe the correlation between post-ROSC ECG findings and acute coronary angiography lesions in out-of-hospital CA (OHCA) pts.

 Retrospective analysis from a prospective database of pts admitted consecutively to the acute cardiac care unit of a tertiary care hospital from September 2006 to April 2019. Post-ROSC ECG of OHCA pts who underwent emergent coronary angiography were blindly and separately classified by 2 cardiologists as follows 1) ST-s elevation, 2) ST-s depression, 3) LBBB, 4) T wave changes/unespecific and 5) normal ECG. If discordant diagnosis, a senior cardiologist made a third and separate analysis. Additionally, coronary lesions were considered to be acute in presence of thrombi or unstable plaque (with or without complete occlusion).

 From 412 pts, 211 had an available and interpretable post-ROSC ECG and underwent emergent coronary angiography. Mean age 60±13 years, male sex 183 (86.7%). Correlation between ECG findings and acute coronary lesions are shown in table 1. Pts with ST-s elevation had an underlying acute coronary lesion in 55.2%. Moreover ST-s elevation had a positive predictive value of 84% and sensitivity of 58.8% for identifying acute coronary lesions. Other post-ROSC ECG findings did not significantly associate acute coronary lesions, in fact LBBB had a high negative predictive value for acute lesions.

 Among post-ROSC ECG findings, ST-s elevation is significantly associated with acute coronary lesions and when identified, an invasive strategy should be considered as established by current practice guidelines. On the contrary, LBBB rarely associates acute coronary lesions at least in OHCA scenario and when its "new onset" is not specified.

This paper presents a set of algorithms used for music recommendations and personalization in a general purpose social network www.ok.ru, the second largest social network in the CIS visited by more then 40 millions users per day. In addition to classical recommendation features like "recommend a sequence" and "find similar items" the paper describes novel algorithms for construction of context aware recommendations, personalization of the service, handling of the cold-start problem, and more. All algorithms described in the paper are working on-line and are able to detect and address changes in the user's behavior and needs in the real time. The core component of the algorithms is a taste graph containing information about different entities (users, tracks, artists, etc.) and relations between them (for example, user A likes song B with certainty X, track B created by artist C, artist C is similar to artist D with certainty Y and so on). Using the graph it is possible to select tracks a user would most probably like, to arrange them in a way that they match each other well, to estimate which items from a fixed list are most relevant for the user, and more. In addition, the paper describes the approach used to estimate algorithms efficiency and analyze the impact of different recommendation related features on the users' behavior and overall activity at the service.

The paper deals with the extended thermodynamical model of thermoelastic interactions in nonlinear elastic solids of anomalous mechanical properties (negative Poisson's ratio materials) including energy dissipation during the thermoelastic damping phenomenon. The model has been based, among others, on Murnaghan's free energy. Numerical simulations show unconventional effects occurring in such materials.


'establish ethnic enclaves within the host countries,' which implies that they pose an additional threat because they are unassimilable (p. 51). In the chapter titled 'The Incommensurability of Liberalism and Puritan Islam' Vann reads into the Qur'an that gender inequality and homophobia are essential to Islam, and claims that it is not possible to reconcile Islam with liberalism and secularism. This highly prejudiced and rather ignorant claim not only completely overlooks the various debates on these issues among theologians, ideologues and scholars of Islam, but also conveniently ignores the significant rise of Islamic liberalism in places like Turkey. Vann's observations are mostly based on immigrant Muslim communities living in the US, yet he does not hesitate to generalize these to the whole 'Muslim World' that actually includes a wide diversity of populations and groups from the secular Muslims of Turkey to Sufi orders of Pakistan to the Algerian rappers in the streets of Paris. Islam certainly has many divergences, controversies, inner inconsistencies, diversity and range of application, and many democrats, radicals, liberals, conservatives, fanatics, fundamentalists, or secularists just as any other religion.


We examine how the electron correlation affects the electron-phonon (EP) interaction in the linear optical absorption spectrum of the one-dimensional (1D) extended Hubbard-Holstein model. A density matrix renormalization group (DMRG) calculation shows that the effect of the EP interaction on an exciton is enhanced by increasing the on-site Coulomb repulsion. This enhancement is in contrast to the effect of the EP interaction on the ground state, wherein the Peierls instability is suppressed by the on-site Coulomb repulsion. The DMRG data with the EP interaction fit with absorption experiments in 1D cuprates better than those for the extended Hubbard model.

The language theoretic operation twist from \cite{JaPe87} is studied in connection with the semiAFLs of languages accepted by reversal bounded multipushdown and multicounter acceptors. It is proved that the least twist-closed trio generated by $\MIR := \{ ww^{rev} \mid w \in\{a, b\}^* \}$ is equal to the family of languages accepted in quasi-realtime by nondeterministic one-way multipushdown acceptors which operate in such a way that in every computation each pushdown makes at most one reversal. Thus, the intersection-closed trio generated by \MIR equals the twist-closed trio with the same generator. and this family is principal both as a twist-closed and as an intersection-closed semiAFL. This is in contrast to the semiAFL of languages accepted by reversal-bounded multicounter machines in quasi-realtime. This family is a well known semiAFL which is principal as an intersection-closed semiAFL with generator $B_1\ := \{a_1^n\Bar{a}_1^n \mid n\in \N \}$, see \cite{Grei78}, but is not principal as a semiAFL. It is here shown that it forms a hierarchy of twist-closed semiAFLs and therefore cannot be principal as twist-closed semiAFL.


This study aimed to see whether there are differences in performance between certified counselor with a counselor who has not been certified in developing guidance and counseling program. In this study population was all counselors at the Junior High School Brebes 155 people by the number of counselors. The research sample was selected using cluster random sampling technique as many as 41 people counselors not certified and 35 certified counselors are scattered in 16 Junior High School. Retrieval of data in this study using a questionnaire. The method of data analysis using different test (t-Test). The difference between the performance of the certified counselor and certified as yet unknown t = 2.35 with a significance level of 5%, N = 76 so that the value df = 74 while it was based on calculations, the t table = 1.99 (with interpolation). This means that t = 2.35> ttable = 1.99 in order to obtain a conclusion that there is a difference in performance between certified counselors and counselors not certified in developing the counseling program.


This paper considers a nonparametric panel data model with nonadditive unobserved heterogeneity. As in the standard linear panel data model, two types of unobservables are present in the model: individual-specific effects and idiosyncratic disturbances. The individual-specific effects enter the structural function nonseparably and are allowed to be correlated with the covariates in an arbitrary manner. The idiosyncratic disturbance term is additively separable from the structural function. Nonparametric identification of all the structural elements of the model is established. No parametric distributional or functional form assumptions are needed for identification. The identification result is constructive and only requires panel data with two time periods. Thus, the model permits nonparametric distributional and counterfactual analysis of heterogeneous marginal effects using short panels. The paper also develops a nonparametric estimation procedure and derives its rate of convergence. As a by-product the rates of convergence for the problem of conditional deconvolution are obtained. The proposed estimator is easy to compute and does not require numeric optimization. A Monte-Carlo study indicates that the estimator performs very well in finite samples. ∗This paper is a revision of the first chapter of my thesis.

"Concentrate all your thoughts upon the work at hand. The sun's rays do not burn until brought to a focus."


EFSA is conducting pan-European dietary exposure and risk assessments related to actual levels of pesticide residues in food commodities. These assessments use the pesticide occurrence data generated under the official monitoring programs of Member States, the consumption data from EFSA's comprehensive food consumption database and pesticide -specific information such as processing factors. Currently no harmonised list of processing factors is available within Europe and worldwide. The overall objective of this project is to develop a database of validated processing factors, which is compatible with the EFSA food classification and description system FoodEx 2. In the first part of the project, a compendium of representative processing techniques was elaborated which serves as a standard description of all relevant processes and as a basis for validation of processing studies. In the second part of the project all relevant processes and raw and processed commodities were coded according to FoodEx2. In the third and last part of the project all processing studies used by EFSA in their Conclusions and Reasoned Opinions issued until 30/06/2016 were re-evaluated according to uniform quality criteria and reported in a database. The database is provided as a flat Excel spreadsheet. Information on processing conditions, on analytical methods, storage stability and GLP was collected from the studies and was used to judge the acceptability of each processing study. The representativeness of the processing conditions applied in the studies was judged by comparing them to the compendium of representative processing techniques. Processing factors (PF) were derived from the studies according to comprehensible calculation rules and based on the residue definitions for monitoring. The individual PF were judged for their acceptability. For each commodity/process/active substance combination a median PF was calculated from the individual ones, based on the trials from one or more studies. The database is a ready-to-use inventory of PF for pesticides in a variety of processed food items. In a pilot project a second database was set up with processing factors based on the residue definition for dietary risk assessment. Extension of this database is recommended.


Insulin icodec is a once-weekly basal insulin in development. This trial investigated if renal impairment affects the pharmacokinetics (PK) of icodec. In an open-label, parallel-group trial, 58 individuals (39 males; mean±SD age 50±13 yrs, BMI 26.5±3.1 kg/m2) were allocated to five groups according to renal function based on measured glomerular filtration rate (GFR): normal renal function (NRF; ≥90 mL/min; N=12), mild (60 to <90 mL/min; N=12), moderate (30 to <60 mL/min; N=12), severe (<30 mL/min; N=12) renal impairment and end‑stage renal disease (N=10). A single s.c. icodec dose (1.5 U/kg) was administered and blood was sampled for PK until 840 h (35 days) post-dose. A minor increase was observed in total exposure (AUC0-840h,SD) with decreasing GFR, but the estimated effect of GFR on AUC0-840h,SD did not differ statistically significantly from zero (-0.069; 95% CI [-0.150;0.013]; p=0.099). Pairwise group comparisons showed numerically slightly higher AUC0-840h,SD and Cmax,SS for renal impairment vs NRF (Figure). AUC0-840h,SD was statistically significantly higher for moderate renal impairment vs NRF. In conclusion, icodec exposure trended to be slightly higher for renal impairment vs NRF. The clinical relevance is however limited as icodec should be dosed according to individual need. Thus, no specific dose adjustment of icodec is required in individuals with renal impairment.

We present examples of polyhedra homeomorphic to a torus such that all of their faces are planar polygons with the same number of sides and all of their vertices are incident to the same number of edges. Neither the faces nor the polyhedra are self-intersecting. We call them regular toroids. Because of their combinatorial regularity, these structures may be attractive to people who find beauty in geometric patterns. It is easy to see that there are three classes of regular toroids. These classes are denoted by the Schlafli symbol {p, q} which means that p edges belong to a face and q to a vertex. Thus the classes are: {3, 6}, {4, 4} and {6, 3}. This corresponds to the fact that one can tessellate the plane by regular polygons in the same manner. Within each class, it is easy to construct representatives with sufficiently large face number. A sufficient condition for this number is that it has at least two factors each of which is greater than two. Figure 1: Representatives of the class {3, 6}, {4, 4} and {6, 3}, with (V, E, F) = ( 42, 126, 84), (42, 84, 42), (84, 126, 42), respectively The question is whether these classes have representatives that do not satisfy this condition. If yes, which of them has the minimal number of vertices or faces? The vertex-minimal representative of the class {3, 6} is the Csaszar polyhedron having (V, E, F) = (14, 21, 7). See [1]. We can show that in the class {3, 6} there is a regular toroid for each 7 ≤ V ≤ 12 such that it is non-intersecting. However, for these smaller V it is difficult to find vertex coordinates that meet this requirement. Figure 2: The polyhedra of the class {3, 6} with V = 7, 8, 10 and 11 In the class {4, 4}, for the polyhedron with minimal number of faces and vertices we have (V, E, F) = (9, 18, 9). For the next polyhedron (V, E, F) = (12, 24, 12). The author does not know if there is a toroid with the face number not satisfying the sufficient condition mentioned in the first paragraph, for example, with F = 10, 11, 13, 14, ... In the class {6, 3} the minimal number of faces is 7. This polyhedron was discovered by the author, and it was Martin Gardner who first called it the Szilassi polyhedron [2]. A metallic sculpture of it is exhibited in the mathematical museum of Fermat's birth house. One can easily construct polyhedra in this class with face numbers 9, 12, 15, ...; in general, this number is of the form a * b, a ≥ 3, b ≥ 3 [3]. Since 1988 we have known a toroid with 8 hexagons (see [4]); however, this is an overarching polyhedron, that is, for each of its faces there is another face such that they have two edges in common.


In the inscription of Oracle Bone Hll : 2 from Zhouyuan, there is the second word "third moon"with a mark of repeat, which the researchers read as "another third moon" and decipher as "a leap third moon". It is noteworthy that this inscription gives a complete narration, and that the word "fifth moon" is between the two "third moons. " Taking the second "third moon" as "a leap third moon" means excluding the "fifth moon," which is obviously unacceptable. But if we read the second "third moon" as the third moon of next year, then the "fifth moon" will just rationally occur between the two "third moons", which will be very appropriate to the meaning of the inscription. Moreover, as relevant bronze inscriptions prove, in the Western Zhou calendar, a leap moon was placed at the end of the year, which also shows that the second "third moon" should not be deciphered as "a leap third moon." Therefore, this word in the Zhouyuan oracle bone inscription does not mean "a leap third moon" but the "thrid moon" of next year.


Provided is a technology of mass-producing conductive bodies, each of which has a current detection head fixed thereto, and has a stable relationship between a detection value and a current value, said current detection head detecting a value of a current flowing in the conductive body. The head is provided with a lens, a magnetooptical element, the conductive body, and a fixing member, and the lens, the magnetooptical element, and the conductive body are fixed to the fixing member. An optical system, wherein light is guided to the magnetooptical element through the lens by means of the current detection head, and light having been subjected to magnetooptical effects by means of the magnetooptical element is guided to the lens, is formed. Since all the members that relate to current detection are fixed to the fixing member, correlative positional relationships among all the members that relate to the current detection are uniquely determined, and the conductive bodies having less variance in current detection characteristics can be mass-produced. The conductive body may be obtained by forming, between the fixing member and the conductive body, a shape for determining the positional relationship between the fixing member and the conductive body, and by fixing the aligned current detection head and the conductive body.


in coherence with external equity characteristics and supply deep insights and shortcoming areas of a brand to strengthen the brand. Yoo & et al. (2000) postulate brand equity is the difference of consumer's selection between the branded product and unbranded product that have the same features. Or in higher education, Mullins et al. (1995) and Nesdale et al. (1995) debated image and prestige in their research inquiring the selection of study place through international students and emphasizing that the absorbing of a university by its credit in a country as a recognized organization. Therefore, building and measuring brand value is a tool to help managers can make the right plans in their development strategy. This study addresses brand equity in higher education. Higher education is a significant level to determine the professional quality of future human resources. Especially in the field of higher education, because customers will be cautious in making service selection decisions, the determination of brand value in the minds of customers directly using educational services to see if the image is consistent with the school's brand positioning strategy is an urgent need for academic managers in the current period. Abstract: This paper researches, synthesizes and gives the university brand equity components and factors from students'perspectives in Hanoi city. University brand value from a student perspective in Hanoi city includes fourelements: Brand Awareness (BA), Brand Impression (BI), Perceived Quality (PQ), and Brand Loyalty (BL). Polling 350 students collected analytical data through questionnaires designed to match students' unique characteristics at universities in Hanoi. The research results contribute to the scientific basis for university leaders in building and developing brands todraw more students in the future.


Mazovian Voivodeship is an area where socio-economic situation is significantly diverse. It is a real challenge for regional development policy which in Poland aims at increasing competitiveness and achieving cohesion by 2020. The use of selected taxonomic measures to compare the development level of selected communes in Mazovia allowed to determine whether the regional policy so far has led to socio-economic growth of all or just some of the investigated communes. Those urban-rural and rural communes of the highest development level in the Mazovia region seem to create a quite coherent area around Warsaw; it was proved by the results of statistical analysis with the use of the relative development level and Hellwig's measure for the years 2002 and 2009.

Spatial helical gears, worm gears with a cylindrical worm, globoid gears, etc., are widely used in most of modern engineering products [1-3; 37; 42]. Cylindrical worm gears are actively used in the creation of metalworking equipment (push mechanisms of rolling mills, presses, etc.), in lifting and transport machines, in drives and kinematic chains of various machine tool equipment where high kinematic accuracy is required (dividing machine tools, adjustment mechanisms), etc.
 In a worm gear a cylindrical worm or its cylindrical helical surface can be cut by various technological methods [49-51], but no matter how the shaping of the worm gear elements' working surfaces is carried out, the worm wheel is cut with a gear cutting tool, whose producing surface coincides with the worm thread's lateral surface [19; 22; 23]. In this regard, the working surface of the cylindrical worm wheel's tooth, even with a non-orthogonal arrangement of axes, is an envelope of a one-parameter family of surfaces that gives a linear contact, which presence makes it possible to transfer a large load using a worm gear.
 For high-quality manufacturing of worm gears, it is necessary to design and manufacture a productive gear cutting tool - an accurate worm cutter, whose shaping (working) surface must be identical to the profiled worm's shaping (working) surface [24-27; 54].
 One of the most important tasks in the implementation of worm gearing is the problem of jamming of the cylindrical worm and the worm wheel' contacting surfaces. This problem is excluded by relieving the contacting surfaces' profile along the contact line. Considering that any violations of contacting surfaces' geometric parameters affect the change in their geometric characteristics, the tasks of accurately determining the adjustment parameters of the technological equipment, used for shaping the worm and worm wheel, enter into in the foreground of the worm gearing elements production.
 In modern conditions of plant and equipment obsolescence, and in particular, of gear cutting machines used for worm gears manufacture, these machines physical wear, implies an inevitable decrease in the accuracy of their kinematic chains. Therefore, in order to maintain the produced gears' quality at a sufficiently high level, it is necessary to use deliberate modification of contacting surfaces when calculating the worm gearing's geometric parameters; such modification reduces the worm gear sensitivity to manufacturing and mounting errors of its elements [28-31].

A novel high-alpha-particle-immunity and high-density dynamic RAM cell with readout signal gain is proposed. The cell is composed of a MOSFET for charge transfer, a MOS capacitor for charge storage and a junction FET (JFET) with buried channel under the MOS capacitor. The buried channel is dynamically switched according to whether there is charge-storage or not. The cell has extremely small collection efficiency for charges generated by alpha-particles, and allows a large amount of leakage charges due to its peculiar structure. Thus, it can achieve high packing density.


The article aims to define the essence of the concept «historic city» in contemporary humanitarian knowledge. The article is based on analyzing the legal and culturological discourses on the historic city. Historical and cultural research method allows us to identify the reasons for the definition «historic city» to appear and trace the process of its development and transformation. The author focuses on the legal context in which the process of understanding the category of «historic city» goes through the search for and justification of unified criteria and signs of «historicity» of the city, determined by the value of architectural and urban heritage, and on assigning the status of «historic» to the city. There are certain criteria used for assessing historical and cultural value of a city. They are sign-markers of time, style and image, sign-symbols and sign-copies used for determining urban planning, historical, functional, architectural, aesthetic, emotional, artistic and scientific-cognitive value of the city historic environment. Apart from the subject of protection (valuable urban objects, planning, three-dimensional structure, compositional and visual connections), the legitimacy of the official status «historic city» is determined by such categories as protection zones and the boundaries of protection zones. The culturological discourse of the historic city is based on an a priori acceptance of the city as a unique phenomenon and then on its comprehensive integrative study. A defining characteristic of the historic city is the thesis of its integrity, the impossibility of «detailed» consideration. Scientists formulate the view of the historic city through the prism of this thesis in different ways: the city as a complex social organism with its own physiology, anatomy and psychology; the city as an integral socio-cultural formation, a complex self-developing system, represented in the material, spiritual and artistic culture; the Russian provincial historic city as a cultural universe, where two major problems come to the fore, i.e. the problem of the formation context and current existence of the historic city and the problem of personality. The author notes that the cultural discourse is more versatile and relevant, and should be taken into account in determining the legal status of the historic city.


Abstract When the choice of estimator for the coefficients in a linear regression model is determined by the outcome of a prior test of the validity of restrictions on the model, it is well known that a minimax (risk) regret criterion leads to the simple rule that the optimal critical value for the preliminary test is approximately two in value, regardless of the degrees of freedom. We show that this result no longer holds in the (likely) event that relevant regressors are excluded from the model at the outset.


Objective: The presently favoured technique of endovascular repair of abdominal aortic aneurysms (EVAR) can fail to fully eliminate the aneurysm when an endoleak occurs. The most common endoleak, type II, is caused by retrograde perfusion of the aneurysmal sac through mesenteric or lumbar arteries. Our hypothesis is that the patency and number of lumbar arteries and thus, the formation of type II endoleaks, can be predicted preoperatively by morphometrically measuring the total psoas area or core muscle index.
Methods: The medical records of all EVAR patients treated at the Marienhospital Aachen between July 2013 und August 2015 were reviewed retrospectively with a special focus on the postoperative formation of endoleaks. In the preoperative CT-scans of the population we morphometrically measured the total psoas area and density. The effect of total psoas area on occurance of endoleaks was assessed using Wilcoxon-signed-rank-test.
Results: 63 patients with a mean age of 72.5 years were treated with EVAR for AAA. There was an endoleak type II occurrence rate of 21.9%. The mean total psoas area was 2412.30 mm². The Wilcoxon-signed-rank-test showed no significant association between the mean total psoas area or density and the occurrence of endoleaks.
Conclusions: In the end we could not demonstrate that core muscle index could be a predictor for endoleak type II. One of the reasons we failed is perhaps the small size of the cohort. We are planning to continue pursuing our hypothesis by appending our data with that of other centers to include a larger number of individuals.


Monitoring tree decline in arid and semi-arid zones requires methods that can provide up-to-date and accurate information on the health status of the trees at single-tree and sample plot levels. Unmanned Aerial Vehicles (UAVs) are considered as cost-effective and efficient tools to study tree structure and health at small scale, on which detecting and delineating tree crowns is the first step to extracting varied subsequent information. However, one of the major challenges in broadleaved tree cover is still detecting and delineating tree crowns in images. The frequent dominance of coppice structure in degraded semi-arid vegetation exacerbates this problem. Here, we present a new method based on edge detection for delineating tree crowns based on the features of oak trees in semi-arid coppice structures. The decline severity in individual stands can be analyzed by extracting relevant information such as texture from the crown area. Although the method presented in this study is not fully automated, it returned high performances including an F-score = 0.91. Associating the texture indices calculated in the canopy area with the phenotypic decline index suggested higher correlations of the GLCM texture indices with tree decline at the tree level and hence a high potential to be used for subsequent remote-sensing-assisted tree decline studies.


Background: Acute lower respiratory tract infections are a common cause of morbidity and mortality in children. Respiratory infections in infants and small children are of great importance because of small airways. Infection may cause a further narrowing and may lead to respiratory distress. To evaluate the etiological factors, clinical profile and outcome of acute respiratory distress in the age group 2 months to 2 years.Methods: This study was conducted in the Paediatric department of Government Mohan Kumarmangalam medical college hospital, Salem, Tamil Nadu, India in the year September 2017-March 2018. Totally 183 cases of acute respiratory distress children were included in the study. A thorough clinical examination was done at the time of admission and management details were recorded into the proforma. Respiratory distress is defined as per WHO protocol as respiratory rate more than 50/minute in infants from 2 months to 12 months of age, and more than 40/minute in children from 13 months to 24 months of age.Results: Of the 72 cases of bronchiolitis, 32 cases (44%) tested positive for IgM at the time of admission and no cases in the control population tested positive for IgM. Of the 72 cases of bronchiolitis in the study population, 52 cases (72%) tested positive for ELISA IgG at the time of admission and 2 cases among the controls tested positive for ELISA IgG.Conclusions: Pneumonia was the most common cause of respiratory illness in the study population. Overcrowding was the major risk factor contributing to acute respiratory illness. Incidence of acute respiratory distress was high among undernourished children.


This paper studies capacity allocation of an energy storage (ES) device which is shared by multiple homes in smart grid. Given a time-of-use (TOU) tariff, homes use the ES to shift loads from peak periods to off-peak periods, reducing electricity bills. In the proposed ES sharing model, the ES capacity has to be allocated to homes before the homes' load data is completely known. To this end, an online ES capacity allocation algorithm is developed based on the online convex optimization framework. Under the online algorithm, the complex allocation problem can be solved round by round: at each round, the algorithm observes current system states and predicts a decision for the next round. The proposed algorithm is able to minimize homes' costs by learning from home load data in a serial fashion. It is proven that the online algorithm can ensure zero average regret and long-term budget balance of homes. Further, a distributed implementation of the online algorithm is proposed based on alternating direction method of multipliers framework. In the distributed implementation, the one-round system problem is decomposed into multiple subproblems that can be solved by homes locally, so that an individual home does not need to send its private load data to any other. In simulation, actual home load data and a TOU tariff of the United States are used. Results show that the proposed online approach leads to the lowest home costs, compared to other benchmark approaches.

Recent advances in multi-layer insulating substrates, such as low temperature co-fired ceramic (LTCC), have motivated novel designs of RF/microwave passive components, such as filters, couplers and power combiners, which attempt to take advantage of the third dimension in order to reduce component size. Such designs are highly desirable for miniature transceiver realizations in portable electronic devices. In addition to advances in new materials and manufacturing processes, an important enabling technology for the realization of such systems is a three-dimensional electromagnetic modeling tool capable of providing the accuracy and computational efficiency necessary for design iteration in a three-dimensional conductor layout. We present a novel approach to the frequency-domain integral-equation modeling of conducting structures embedded in a homogeneous dielectric that is shielded by two perfectly-conducting ground planes. Novel closed-form expressions for the impedance matrix elements arising from a Method of Moments solution of the integral equation are developed. These exact expressions were found to improve the computational efficiency over direct numerical integration by two orders of magnitude, greatly reducing matrix fill times. Several simple structures, including a transmission line and three microwave filters are simulated to test and validate the developed expressions.
