The computation of the Nth root produces a compression of the spectrum for some types of analytic signals. Once the spectrum has been shrinked in the frequency domain, the signal can be decimated in the time domain, leading to compression. The Nth root calculation raises some problems which are discussed, like phase jumps related with zero crossings of the amplitude. Results of simulations with sinusoids and speech signals are reported. More work is needed to make the approach practical.


Data are available on a 1% sample of social security covered employees by industry, age, sex and race for years 1960 and 1965 and their mortality through 1972. Previous papers have reported on overall rates by age, sex and race and on industries in which mortality appears to be increased among younger workers. In this paper mortality ratios, compared to the expected overall race-sex-age specific rates for this population, are shown for the Standard Industrial Classification two-digit-industry classes for the 1960 and the 1965 cohorts. Among women employed in four industries involving chemical exposures, an abrupt increase in mortality occurred around 1965. Possible reasons for this are discussed. The epidemiologic usefulness of social security mortality data for occupational and preventive purposes and for surveillance is emphasized.


Reduction of β-sulfenylated α,β-unsaturated ketones (1) with sodium borohydride (NaBH4) in the presence of a catalytic amount of metal halide (CoCl2 or NiCl2) gave the saturated ketones (3). However, FeCl2, FeCl3, CuI, and CuCl2 showed no effect in the reduction of 1.


As a basic approach to viewing the world,poetry,with its highly condensed language and rich imagination,gives vivid expression to people's recognition of and insight into the physical realm.Time images in both classical Chinese and English poetry are analyzed,and it is found that time images share common cross-cultural implications based on the universal perception of the objective existence of time.Meanwhile,the wholeness and intuitiveness in Chinese thinking and the duality and logicality in Western thinking are also embodied in the time images.The awareness of cultural generality and difference is crucial for cross-cultural communications.

From this analysis, this paper shows the critical success factors for UGC in ubiquitous business environments. In addition, this paper analyzed the attributes of UGC through the research of literature reviews and expert reviews. Based on this research, many companies are encouraged to develop successful digital content generated by end-users.


A controlled-NOT gate using linear optics is constructed and evaluated. A 33% reflective mirror is used in order to obtain Non-classical interference. The probability of obtaining the correct output averaged over all four logical inputs is 85%. Quantum computing promises to solve efficiently problems such as factoring large integers [1] and combinatorial optimization [2]. One of the greatest challenges is to implement the basic quantum computational elements in a physical system and to demonstrate that they can be scalably and reliably controlled. The main advantage of a photonic implementation for quantum computation is photon robustness against decoherence and the availability of single-qubit operations. However, the lack of nonlinear interaction between photons that is needed for implementation of controlled not gate(C-NOT gate) is a major obstacle. In a recent work In recent work, Knill, Laflamme and Milburn (KLM) [3] proposed a scheme for quantum computation based on linear optics, demonstrating that this obstacle can be overcome. By now, various C-NOT gates using linear optics have been suggested [4-7] and demonstrated [8-11]. The C-NOT gate is a gate that acts on two qubits. The first qubit is called a control qubit |C>, and the second qubit is the target qubit |T>. If the control qubit is |0> then the target qubit value is left unchanged. If the control qubit is |1> the target qubit is flipped. Therefore, the ideal C-NOT gate can be described by the following table. UC-NOT|00> = |00> UC-NOT|01> = |01> UC-NOT|10> = |11> UC-NOT|11> = |10> We have demonstrated the C-NOT gate proposed by Hofmann and Takeuchi [12]. The schematic setup of this C-NOT gate is shown in Fig.1. Photon 1 and Photon 2 should be input at the same time. For this purpose, we adopted pairs of photons generated through the process of parametric down conversion. The two photons are prepared in a two qubit state to be input into the gate using half wave plates (HWP). The gate consists of four polarizing beam splitters (PBS) and three 33% reflective beam splitters. The two outputs are polarization analysed using HWPs and PBSs. We prepared single photon qubits in the polarization states |V> ≡ |0>, |H> ≡ |1> for the control qubit, and 1/ 2 (|V>+|H>) ≡ |0>, 1/ 2 (|V>−|H>)≡ |1> for the target qubit, where |V> and |H> are the vertical and horizontal polarization states, respectively. To characterize the operation of this gate we measured the output of the gate for each of the four possible logical basis input states: |C>|T> ≡ |CT>=|00>, |01>, |10> and |11>. The experimental result is shown in Fig.2. The fidelity, defined as the probability of obtaining the correct output averaged over all four possible inputs, is 85%. Loss FIG.1.

We study the spectrum of the one-dimensional Schr\"{o}dinger operator $H_0$ with a matrix singular distributional potential $q=Q'$ where $Q\in L^{2}_{\mathrm{loc}}(\mathbb{R},\mathbb{C}^{m})$. We obtain generalizations of Ismagilov's localization principles, which give necessary and sufficient conditions for the spectrum of $H_0$ to be bounded below and discrete.


A study on the Islamic financial services industry is a comprehensive analysis of the financial sector that operates in accordance with Islamic principles, also known as Shariah-compliant finance. Shariah is Islamic law and code of conduct derived from the divine principles mentioned in primary sources of Islam i.e., Quran and Sunnah. Islamic finance is guided by the principles of Islamic law (Shariah), which prohibit activities such as charging or paying interest (usury) and engaging in speculative transactions. Instead, Islamic finance promotes ethical and equitable financial practices. This research highlights the substantial growth and financial soundness of the Islamic financial services industry, and it suggests a positive outlook for the sector's future. Islamic finance has gained momentum globally, attracting both Islamic and non-Islamic investors who are interested in ethical and Shariah-compliant financial solutions.


We present an application of variational multiscale (VMS) turbulence modeling methodology to the computation of laminar and turbulent flow around a circular cylinder. Isogeometric Analysis (IGA), based on Non-Uniform Rational B-Splines (NURBS) functions, is utilized in order to achieve higher-order approximation of the solution as well as exact geometry representation. We consider laminar and turbulent flows around a circular cylinder and demonstrate the applicability of the methodology to both regimes.

new knowledge and offered fair and thorough treatments, but raise as many questions as they answer. Because the catastrophes in Vietnam were not only military ones, did the defeat of the ROV truly arise from strategic mistakes, failing morale, and North Vietnamese deception at the Paris peace talks? Or was something deeper at work, like the culmination of prolonged hostilities pitting insurgents against nations foolishly trying to impose an image of themselves on a faraway land? There is truth to Veith's words that US opposition at home brought the war to a premature end, despite gains made in the war in the early 1970s. But it is also true that nationalists and communists had, for decades, been claiming other subtler victories, planting the seeds of calamity before a shot was even fired.


Passive heat transfer from enclosures with rectangular fins is studied both experimentally and theoretically. Several sample enclosures with various lengths are prepared and tested. To calibrate the thermal measurements and the analyses, enclosures without fins ("bare" enclosures) are also prepared and tested. Surface temperature distribution is determined for various enclosure lengths and heat generation rates. Existing relationships for natural convection and radiation heat transfer are used to calculate the heat transfer rate of the tested samples. The theoretical results successfully predict the trends observed in the experimental data. It is observed that the contribution of the radiation heat transfer is on the order of 50% of the total heat transfer for the tested enclosures. As such, a new correlation is reported for calculating optimum fin spacing in uniformly finned surfaces, with rectangular straight fins, that takes into account both natural convection and radiation.© 2011 ASME

Nowadays, the level of competitiveness of the fast food industry in Malaysia is intense. New competitors are emerging and current players in the market are striving to increase their market share through opening new branches in different parts of cities. The key target market for these companies would be the Generation Y customers due to their lifestyle and consumption habits. In order to be competitive in the industry, fast food companies should venture into instilling customer loyalty in the hearts of the consumer as it cost lesser and has the long-term benefits in term of profitability. Therefore, this research would aim to investigate the factors which would affect the enhancement of customer loyalty among the Generation Y customers in Malaysia. Besides that, this research would also investigate the effect of customer satisfaction as the mediating variable between those factors and customer loyalty. As Malaysian fast food companies is situated in many different towns with different population, this research would also compare the perception of factors which are important to customer loyalty between two towns which have different populations. The factors chosen for this research are food quality, price, service quality, environment and location. According to the results, the factors which have significant effect on both sets of respondents are the food quality, service quality environment factor. Therefore, it can be deduced that these are the factors which affect the overall Generation Y customers in terms of their customer loyalty. The data also shows that customer satisfaction factor mediates the relationship between these factors and customer loyalty.

Unification of the Bardeen, Cooper and Schrieffer (BCS) and the Bose‐Einstein condensation (BEC) theories is surveyed in terms of a generalized BEC (GBEC) finite‐temperature statistical formalism. A vital distinction is that Cooper pairs (CPs) are true bosons that may suffer a BEC since they obey BE statistics, in contrast with BCS pairs that are "hard‐core bosons" at best. A second crucial ingredient is the explicit presence of hole‐pairs (2h) alongside the usual electron‐pairs (2e). A third critical element (particularly in 2D where ordinary BEC does not occur) is the linear dispersion relation of CPs in leading order in the center‐of‐mass momentum (CMM) power‐series expansion of the CP energy. The GBEC theory reduces in limiting cases to all five continuum (as opposed to "spin") statistical theories of superconductivity, from BCS on one extreme to the BEC theory on the other, as well as to the BCS‐Bose "crossover" picture and the 1989 Friedberg‐Lee BEC theory. It accounts for 2e‐ and 2h‐CPs in arbitrar...


The Sino-European relations,which is a kind of global and strategic one,is not only decided by the bilateral relations itself but also by the global structure.As indicated in Kondratieff's long wave theory,in sector B with the decline of the hegemony and the emergence of multi-polarization,the insufficiency of global public goods and imbalance in social dimensions will be intensified.Therefore,in the age of hegemony declining,there exists abundant space for China and Europe to explore,esp.in global governance and the maintenance of global and regional stability.But the precondition for this cooperation is the discarding of Euro-centrism,the implementating of multi-dimensional global cooperation,the re-thinking of diversified culture,the understanding of different development models and the rational balacing between public politics and international politics.Only with this strategic insights could the Sino-European relations be devloped globally.


Thermographic phosphors can be employed for optical sensing of surface, gas phase, and bulk material temperatures through different strategies including the time-decay method, time-integrated method, and frequency-domain method. We focus on the time-integrated method, also known as the ratio method, as it can be more practical in many situations. This work advances the ratio method using two machine vision cameras with CMOS detectors for full-field temperature measurements of a solid surface. A phosphor calibration coupon is fabricated using aerosol deposition and employed for in situ determination of the temperature-versus-intensity ratio relationship. Algorithms from digital image correlation are employed to determine the stereoscopic imaging system intrinsic and extrinsic parameters, and accurately register material points on the sample to subpixel locations in each image with 0.07 px or better accuracy. Detector nonlinearity is carefully characterized and corrected. Temperature-dependent, spatial non-uniformity of the full-field intensity ratio—posited to be caused by a blue-shift effect of the bandpass filter for non-collimated light and/or a wavelength-dependent transmission efficiency of the lens—is assessed and treated for cases where a standard flat-field correction fails to correct the non-uniformity. In sum, pixel-wise calibration curves relating the computed intensity ratio to temperature in the range of T = 300–430 K are generated, with an embedded error of less than 3 K. This work offers a full calibration methodology and several improvements on two-color phosphor thermography, opening the door for full-field temperature measurements in dynamic tests with deforming test articles.

The author shows that a multiplier already proposed by T. Rhyne and N.R. Strader (see ibid., vol.C-35, p.896-901 (1986)) for unsigned numbers can be used for two's complement numbers as well, provided only that the content of the input registers is held constant, after the introduction of the operand's sign bits, for a number of clock periods equal to the operand's length. The result is derived by the properties of sign-extended two's complement numbers. The known multiplier includes a linear array of (5, 3) parallel counters and a set of three static registers for the internal carriers. It is shown that a logically equivalent multiplier can be built using two linear arrays of full adders and two carry registers. In a faster circuit, an additional carry register is required. >


This study examines the relationship and interaction between telehealth and insurance. Recently, the need for non-face-to-face treatment or telehealth is increasing due to Covid-19. Telehealth is expected to grow exponentially, thanks to advances in IT and artificial intelligence techniques. Consequently, it is necessary to analyze this trend from the perspective of the insurance industry. Though telehealth may lead to increased utilization of health services, it will improve the health of policyholders and reduce mortality thereby improving the profit of insurance companies. Therefore, insurance companies are projected to actively utilize telehealth and encourage the insured to use it. This study analyzes the effect of telehealth on the profit and loss of insurance companies and suggests what incentives these companies can give to the insured.

Objective: Many children at risk for negative outcomes related to untreated attention deficit hyperactivity disorder (ADHD) do not receive necessary mental healthcare. Parents' mental health-seeking behavior is important in the early identification of ADHD and preventing comorbidities with ADHD. Parents may experience some barriers that may delay or stop parents from seeking mental healthcare for their children. Method: This systematic review summarized existing evidence of parents' barriers to seeking mental healthcare for their children at risk of ADHD. Results: This review included 21 studies that address different parental barriers under the three levels of the social-ecological model, including individual, interpersonal, and community levels. Conclusion: Raising parents' awareness of the process of seeking mental healthcare has the potential to help identify children at risk for ADHD earlier. Developing psychoeducational intervention that improves parents' seeking behavior and reduces barriers toward seeking mental healthcare is needed.


The nutrient load for the whole Danube River reached a maximum within the 1980-1990 period, followed by a decrease to recent days (Behrendt & Schreiber (2004), daNUbs project, Final Report (2005)). Most of these conclusions were derived by a modeling approach assuming that the Iron Gate Reservoir trapped about 1/3 of the passing nutrients. Other authors were of the similar opinion (Rojdestvensky (1990)). However, Teodoru & Wehrli (2005) showed that recently the reservoir has been releasing small amounts of nutrients rather than retaining them. Its storage capacity should have decreased by 20% since the start of reservoir operation.


BACKGROUND
Left ventricular assist device (LVAD) implantation is among the most effective treatment options for patients with severe heart failure. Although previous studies have examined the factors related to peak oxygen uptake (peak VO2 ), they were limited by the few patients involved and their focus on medical and physical functions. Therefore, this study comprehensively examined the factors associated with peak VO2 , which is an important prognostic factor in patients with implantable LVADs.

METHODS
Eighty-nine patients who underwent initial LVAD implantation and were eligible for cardiopulmonary exercise testing (CPX) between May 2014 and September 2021 were included. The patients' mean age was 48 ± 12 years, and 70% were males. Based on previous studies, the cut-off was set at 12 and 14 mL/kg/min for patients taking β-blocker and those not taking β-blockers, respectively. Furthermore, factors associated with peak VO2 were examined using multivariate logistic regression analysis.

RESULTS
The mean time from surgery to CPX administration was 73 ± 40 days. The high group had a higher cardiac index, right ventricular stroke work index (RVSWI), and isometric knee extensor muscular strength and lower Patient Health Questionnaire-9 (PHQ-9) and B-type natriuretic peptide values than the low group. Multivariate logistic regression analysis showed that RVSWI and KEMS were positively correlated, whereas PHQ-9 was negatively associated with peak VO2 .

CONCLUSION
Right ventricular function, depressive symptoms, and lower limb muscular strength were associated with exercise capacity in patients with implantable LVADs.


Let F be a graph consisting of a triangle with a pendant leaf dangling from each vertex. A graph is {K1,3, F}-free if it contains no induced subgraph isomorphic to K1,3 or F. We give a stronger structural characterisation of {K1,3, F}-free graph with which we obtain a more general result than that in [1] as follows: Given any two venices in a 2-connected {K1,3, F}-free graph, if there exists a shortest path between them containing no 2-cutset of the graph, then the graph has a Hamilton path cormecting these two venices.


The Code division multiple access (CDMA) and adaptive antenna system(AAS)system are two approaches that show realpromise for increasing spectrum efficiency. In this research, we investigate the performance of AAS in the CDMA transceiver. The CDMA transceiver has been developed to adaptively correct antenna impedance mismatch.AAS has been deployed at the receiver module to reduce the fading effects caused by proposedStanford University Interim(SUI)channels model. SUI channel model proposes a set of six empirical time-dispersive channels for three typical terrain type'sAAS uses various beamforming techniques to focus the wireless beam between the base station and the subscriber station. In this work, the transmitter (SS) and receiver (BS) are fixed and AAS installed at the receiver is used to direct the main beam towards the desired LOS signal and nulls to the multipath signals. Least Mean Square (LMS) algorithm is used. It has been proved through Matlab simulations that the performance of the system significantly improves by AAS in SUI channel model has been proposed for simulations, design, development and testing of technologies suitable for CDMA transceiver. The performance of the system more increases by increasing the number of antennas at receiver. Keyword: OFDM, CDMA, Antenna, adaptive, Beamforming, AAS.

Oncotype DX recurrence score identified 50% (15/30) patients in low risk group (Recu...


ABSTRACT This paper summarizes results from a recently concluded research project sponsored by the Gas Research Institute, the Petroleum Research Technology Council, and the US Department of Energy. The primary objective of this work has been to improve the state-of-the-art for designing and operating single and multiple caverns in thin bedded salt formations. The effort has included a geologic and geomechanical review of the Permian, Michigan, and Appalachian basins, followed by geomechanical modeling for single and multiple caverns in layered media. A modified creep viscoplastic model has been developed and implemented in Flac3D to simulate bedded salt material behavior. Both cyclic pressure operations and direct pressure drawdown are simulated. Cavern design parameters are varied to evaluate how they influence propagation of damage and the deformation of cavern. These are the cavern pressure, operating conditions, cavern size expressed in terms of height/diameter (H/D) ratio, overburden stiffness and roof thickness. The baseline results for single cavern simulations illustrate a shear stress distribution primarily around the cavern top and bottom corners, salt damage mainly around the cavern sidewall and slippage in the top interface between the salt formation and the anhydrite layer. During cyclic pressure operations, the shear-stress zones propagate into a wider region, which is responsible for an increase in the amount of slippage in the interface. During cyclic pressure loading, the magnitude of the maximum shear stress does not increase, resulting in no additional damage (micro-cracks) in the surrounding salt. The influence of the overburden stiffness is shown to be a critical parameter on the overall cavern response. A substantial part of the weight of the overburden material is carried by the anhydrite layer and by the cavern roof itself. For this particular case, the anhydrite reaches it tensile limit and fails. This failure implies that the cavern roof is subjected to a much higher load and therefore the amount and extension of damage increases substantially. We further evaluate minimum safe center to center distance of multiple horizontal caverns. We find that a center to center distance of two cavern diameters is not sufficient to eliminate the mutual interaction. Increasing the center to center distance to three cavern diameters, however, generally eliminates most interaction.


This study explored the relationship between Australians' perceptions of climate change, its impact on the Great Barrier Reef (GBR), and predictors of environmentally responsible behavior (ERB). Our hypothesized model suggested that general attitudes toward climate change, social pressure for engaging in ERBs (subjective norms), and perceived behavioral control (PBC) over ERB would be positively related to intentions to engage in ERB. We hypothesized that attitude, subjective norms, and PBC would negatively influence the constraints of ERB, intention to engage in ERB, and actual ERB. We used data from a survey of Australian residents on the impacts of climate change and individual human ERB on the GBR to test our hypotheses. The most important predictor of intention to engage in ERB was perception of one's control over the behavior. For both residents and nonresidents, attitudes toward climate change were negatively associated with constraints impinging on their ability to adopt ERBs – although this effect was much more pronounced for nonresidents. By emphasizing the accessibility/easiness of environmental behaviors, GBR marine park managers can reinforce perception of individual control over behaviors and reduce the constraints to engaging in ERBs.


The titania nanocoatings on indium tin oxide (ITO) were succefully obtained by the sol-gel process in an aqueous solution using the titanium diethanolamine complex as the precursor. FT-IR, UV – VIS, Raman spectroscopy and X-ray diffraction techniques have been used to investigate the chemical and physical changes during the sol-gel process and the characteristics of the TiO2 powder precursor. In this paper, we report on the preparation and characterization of TiO2 films prepared using the hydrolytic sol-gel process and deposited on ITO glass substrates by spin coating technique.


ABSTRACT The paper describes the testing for termite resistance of a lesser-utilised tropical species known as kruma (Klainedoxa gabonensis) in order to evaluate its potential for the building, construction and related wood-consuming industries. Results suggest that kruma heartwood can be rated as very durable and the sapwood as durable. It is concluded that utilisation of this wood species could reduce over dependence on traditional primary species.


Adjuncts are characteristically optional, but many, such as adverbs and adjectives, are strictly ordered. In Minimalist Grammars (MGs), it is straightforward to account for optionality or ordering, but not both. I present an extension of MGs, MGs with Adjunction, which accounts for optionality and ordering simply by keeping track of two pieces of information at once: the original category of the adjoined-to phrase, and the category of the adjunct most recently adjoined. By imposing a partial order on the categories, the Adjoin operation can require that higher adjuncts precede lower adjuncts, but not vice versa, deriving order.

The results show the clusters of digital technologies and their research collaboration networks. The review intends to provide a knowledge base and evaluation of applications for these technologies. It is the intention of this paper to facilitate the understanding of scientists and policy makers in how digital technologies can address the SDGs and which ones will be most relevant in 2030.


The Internet paradigm implies the potential for infinite informational interconnectivity. In practice, it fast approaches a level of intensity, complexity etcetera where dedicated, say one-to-one, ad-hoc solutions hamper responsible usage and also further development. Generic technical solutions have of course been developed and made available as infrastructure. Being an informational infrastructure, however, it should include provisions for conceptual variety. Metapattern, as a method for information modeling, supplies the perspective from which to recognize how requisite variety for the conceptual aspect of information is still lacking from current informational infrastructure. Metapattern also allows to recognize work from earlier epochs, i.e. when the practical problems of managing informational interconnectivity were unheard of. It appears that some thinkers already developed rich conceptual frameworks, say, ontologies, catering to a variety that is now generally impossible to deny. An example is Justus Buchler, an American philosopher. After a short introduction to Metapattern, Buchler's metaphysics of natural complexes is outlined and discussed. His work should inspire taking information management to support interconnectivity such as the Internet delivers, and should continue to deliver unambiguously.


As use of battery-operated machines, such as hand-held computers and PDAs, becomes wider, low-voltage/low-power DRAMs are required. Low-voltage technologies are also required in giga-scale DRAMs with scaled-down voltage. This paper describes low-voltage circuit design techniques to meet these demands.


Using different concentrations of chitosan,methylcellulose and single glyceride,different ratios of chitosan composite membrane coating were made to study the physiological changes of cucumber based on the orthogonal experiment of L9(33).The results indicated that chitosan composite membrane characteristic was good,which could effectively maintain the cucumber sensory quality,reduce weightlessness lose,respiratory intensity and hardness of cucumber,and could also inhibit the loss of soluble solid and chlorophyll content.The preservation effect of chitosan achieved the remarkable level.Optimized concentration of the chitosan composite film was the ratio of 2.0 % chitosan,0.2 % single glyceride and 0.2 % methylcellulose.


During the advancement of teacher education reform,the reform of curriculum structure of educational subjects namely the education specialization' is paid more and more attention to.At first,the article analyses the problem of teacher professionalization,then explores the integrated optimization of curriculum structure of education subjects and the organization and management about this kind of curriculum.


Priapism is a persistent penile erection unrelated to sexual activity caused by disturbances in the mechanism controlling penile detumescence and the maintenance of penile flaccidity. It is a urological emergency and if left untreated it may result in impotence. There are many causes of priapism but priapism following regional or general anesthesia is rare, with incidence 0.1-1% [1,2]. When it occurs during urological procedures it may cause a delay or cancellation of the proposed surgery.


Since the discovery of energy, safety has been a paramount subject matter. This, we can see in today's electrical systems where protective devices such as fuse and circuit breakers are used to prevent fire hazards resulting from overload, overvoltage and short circuits. However, with all the revolution in technology, these options may be considered less smart since the fuse, made with wire strands calculated for specific current capacity faults permanently when the specified current rating is exceeded. While the circuit breaker which is made up of mechanical switch fails as a result of carbon forming and the wearing away of the contacts because of arcing. As a means of improvement, this paper presents the design and development of an automatic single phase protective device using solid state relay (SSR). This study is to ensure automatic cut off from power supply in cases of overvoltage (above 240 V AC) or when overload and short circuit (current above 8amps) is detected without permanent damage of a fuse placed along current path. Also the design will ensure that there is an automatic close circuit whenever the trigger switch is (momentary switch) is closed. The system is achieved via the use of PIC micro-controller, current sensor and other discrete components. The system is tested and works well inhibiting the frequent faulting of fuses. It also helps to prevent hazard as a result of overvoltage, overload and short circuit and ensures a close circuit when the trigger switch is closed.


The main goal of this study was the evaluation of the reducing sugars quantity obtained from the wheat straws using the enzymatic complex Accellerase 1500 from Genencor in different conditions of alkaline and alkaline-peroxidic pretreatment. In the first phase we observed the induced modifications for the lignocellulosic materials at the cellulasic attack by the application of some alkaline treatments upon them. At the same time, we also observed the way in which the concentration of the alkaline solution influences the results of the enzymatic attack applied afterwards to the lignocellulosic materials. We used NaOH solutions at concentrations of 0,5 %, 1,0 %, 2,0 % and 4 %. From the data obtained we can conclude that the best results have been seen in the case of high concentration NaOH solutions. In the second phase we tried to obtain some results with the same efficiency as in the previous phase but by applying an alkaline pretreatment coupled with a peroxidic pretreatment. For this purpose we tested several hydrogen peroxide concentrations (of 0,5 %, 1,0 %, 1,5 % and 2 %) , keeping constant the concentration of the NaOH solution. The reducing sugars production was evaluated at the enzymatic hydrolysis periods of 24 and 48 h by the DNS method. The maximum content of reducing sugars from the analyzed raw material was obtained in the case of the combined alkaline-peroxidic pretreatment at 100 ° C for 2h using  NaOH of 4 % concentration and H 2 O 2 of  2,0 % concentration.


Multilayer gratings are artificially patterned multilyer thin films with the periodicities both in the lateral and normal directions which renders them attracting for microelectronic and optical applications. A proper structural characterization is of primary importance. To test the capability of the X-ray reflectometry technique to fulfil this task, a tungsten/silicon multilayer grating prepared by electron beam evaporation and electron beam lithography was studied both in the coplanar and non-coplanar geometries., the nominal lateral and normal periods being 800 nm and 8 nm, respectively. The coplanar measurements were evaluated within the dynamical theory of X-ray scattering on rough gratings and provided the structural parameters of a real structure with a reasonable precision which are close to the nominal ones. The results revealed also some imperfections of the deposition and masking procedures which are discussed. The non-coplanar measurements were evaluated qualitatively using three-dimensional constructions in the reciprocal space. The advantage of the technique used is its non-destructive character and a simultaneous access both to the surface shape of the grating as well as to its internal structure.


Power systems across the world are deploying large numbers of high sampling rate synchronized phasor measurement units at the bulk transmission level. As PMUs generate large volumes of data, transmitting and storing this data for future studies becomes challenging. An attractive solution to this problem is to compress the data using efficient compression algorithms. This paper presents a novel lossy compression algorithm which utilizes the characteristics of power system measurements to improve the compression. Specifically, ideas from image compression are adapted to exploit the spatio-temporal correlations induced by the network in the measurement data. The effectiveness of the compression algorithm is judged based on the space savings and accuracy of data reconstruction. The results presented show that compression ratios as high as 95:1 can be achieved using the algorithm.


Rice is the main food commodity of the Indonesian people, almost all residents in this country consume rice every day. This causes rice commodities to have a very strategic value, apart from being in control of the lives of many people, it can also be used as a parameter of the country's economic and social stability. This study discusses the application of K-Means Clustering Algorithm for Grouping Retail Prices of Rice in Traditional Markets. The source of this research data is collected based on documents describing the retail price group of rice produced by the National Statistics Agency. The data used in this study are data from 2011-2016 consisting of 33 cities. Data is processed by clustering in 3 clusters, namely high population level clusters, medium and low population level clusters. Centroid data for high population level clusters 10,776, Centroid data for moderate population level clusters 9,436 and Centroid data for low population clusters 8,590. To obtain an assessment based on the grouping of the average retail price of rice in traditional markets in 33 cities with high clusters (C1) of 11 cities namely Padang, Pekanbaru, Tanjung Pinang, Bandar Lampung, Jakarta, Pontianak, Palangkaraya, Banjarmasin, Ternate, Jayapura and Manokwari for medium cluster (C2) as many as 11 cities and for low cluster (C3) as many as 11 cities. From the results of this study can be used as input for the government, especially in cities, so that cities that are included in the high cluster can normalize the retail price of rice in each city area.


At the start of Yen's internationalization,there were also difficulties for Yen to be widely used in the trade settlement.It was attributed to the underdeveloped international financial market in Japan,which seems to be similar with the argument of RMB in these days.Since the latter of 1980s,liberalization of financial market was substantially pushed forward in Japan,yet relatively small progress was made in the area of Yen used in the trade settlement.Therefore,the researches shifted to follow the pricing mechanisms and characters of structure in the trade,which may be studied in a micro foundation.And the function as store of value for an international currency is ultimately derived by the primary function,such as a medium of exchange.Consequently the weakness of Yen's primary function results the instability of Yen's role as a reserve currency.It is inevitable for China Yuan to meet the similar embarrassment,and so the lessons from Japanese Yen are valuable.


Educating undergraduates to become master learners during primary care rotations is no easy task. Typically, attachment to primary care is short and often block-based with more time spent in hospital ward settings. Furthermore, there is often no continuum from primary to secondary care with learners having limited opportunities following patients along their journey. Educators in this domain have the added pressure of ensuring sufficient coverage of curricula in a condensed period of time. Add to this the often longstanding relationships built up between patients and their primary care doctors further exacerbating the issue with regards to the interaction between the learner and patient.

When it comes to learning, adoption of learning theory is paramount.1 …


Saline permafrosts are, as a rule, found in a plastically frozen state. In conformity with Construction Rule and Regulation 2-02-04-88, beds composed of these soils should be considered with respect to two groups of limiting states bearing capacity and deformations. No computed deformation characteristics of frozen saline soils are given in this Construction Rule and Regulation, and their determination is not discussed. Development of methods of predicting the long-term deformations of frozen saline soils over a period of time comparable to the service life of structures is therefore an extremely important problem. Above all, it is necessary to establish the applicability of solutions employed in the area of the creep prediction of plastically frozen soils with no readily soluble salts to saline soils. At the present time, these solutions are based on parametric equations obtained on the basis of creep theories (aging, hardening, flow). In these equations, the relationship between strains, stresses, and time is in explicit form [1]. The equation of the theory of hereditary creep is also used with the vanishing-creep kernel obtained by Zaretskii [2] for plastically frozen soils. Moreover, a number of authors have proposed empirical relationships that include experimental parameters [3]. The possibility of using methods of time analogies to predict the long-term deformation of plastically frozen soils is also demonstrated [4]. Parameters established on the basis of experimental laws governing the deformation obtained during a comparatively short period of the creep testing of frozen soils (hours, days) is used in all of the methods enumerated. These laws are then assumed constant during the course of the entire prediction period, the duration of which exceeds the experimental time by several orders. The accuracy of the prediction depends on to what extent the equation expressing laws governing deformation during the test period is valid for description of the deformation process during the course of the overall prediction time. Assessments of the reliability of long-term strains obtained by computation are also required for frozen saline soils. Test data on the basis of which it is possible to confn-m computed strain values are a criterion of such an assessment. For frozen saline soils, research directed toward comparison of predicted and experimental strain values assume particularly critical significance, since the character of the manifestation of the rheological properties differs, by nature, from that for other types of plastically frozen soils (peaty, heavily iced, highly silted). This difference is caused by the fact that the content of unfrozen water is the basic factor determining the increased deformation of saline soils, while creep is also determined by the viscoplastic properties of the solid components ice and biogenic particles in peaty, heavily iced, silt-laden soils. Methods of predicting long-term deformation have been proven on the basis of test data (more than four years) from research on the creep of frozen saline soils in the Yamal Peninsula, and recommendations given for their use. Experiments were conducted in the underground laboratory of the Amderma Scientific-Research Station, in whose compartments a constant temperature of minus 3 ~ is maintained. Sand, sandy loam, and clayey loam were tested. Sandy loam and sand specimens were removed from deposits of the third Zyryanka-age marine terrace in outcrops of the left bank of the Erkuta-Yakha River 20 km from its mouth. The clayey loam was sampled at a depth of 1-3 m in the central part of Yamal Peninsula at the latitude of the Cape of Kharasavi in marine Kazantsevsk deposits located to the east of Lake Tyurin-To.


Cesarean section (CS) is increasingly replacing vaginal delivery, which is concerning due to associated complications. World Health Organization (WHO) recommends robust classification such as Modified Robson's criteria for decision making to minimise non indicated CS. This study was planned to see the applicability of Modified Robson's criteria in assessing causes of CS. To classify and compare indications of CS using the WHO modified Robson's criteria. The present study was a retrospective study conducted at Era's Lucknow Medical College over 24 months. Due approval was obtained from ethics committee before commencing the study. All cases who underwent CS from 1st January 2018 to 31st December 2019 were analysed, data classified in accordance with the WHO Modified Robson's criteria and analysed. Parameters used for analysis included gestational age, parity, number of foetuses, history of previous CS, fetal lie and presentation, induced or spontaneous labour, indication of CS and any associated high risk factors. Of 1929 deliveries, 621(32.2%) had CS. A total 500 CS were evaluated. The major contributor to overall CS rate was Group 5 [30%], 10 [17.4%] and 1 [16.4%]. Modified Robson's classification could be easily applied to our data set and helped in identification of the main groups which contributed majorly to the overall CS rate viz. previous CS, nulliparity, prematurity and induced labours. It also helped us in identifying the subgroups which require more surveillance and monitoring. It is important to focus on Group 5, 10 and 1 which constitute 63.8% of total CS being done.

The ring models described here were developed to account for the dynamical problems posed by the narrow rings of Uranus. Some of these rings are now known to be eccentric, inclined, nonuniform in width, optically thick, and narrow, with very sharp edges. The eccentric rings have common pericenters and large, positive eccentricity gradients. The theory of shepherding satellites successfully accounts for most of these features and can also account for some features of the narrow Saturnian rings, in particular, waves, kinks, and periodic variations in brightness. Outstanding problems include the putative relation between eccentricity and inclination displayed by eight of the nine Uranian rings, and the magnitudes of the tidal torques acting on the shepherding satellites. The horseshoe-orbit model, although viable, probably has more application to the narrow rings from which the Saturnian coorbital satellites formed. The angular momentum flow rate due to particle collisions is a minimum at the Lagrangian equilibrium points L(4) and L(5), and one can expect accretion to be rapid at these points.

Data analysis is used to test the hypothesis that "hitting is contagious". A statistical model is described to study the effect of a hot hitter upon his teammates' batting during a consecutive game hitting streak. Box score data for entire seasons comprising streaks of length games, including a total observations were compiled. Treatment and control sample groups () were constructed from core lineups of players on the streaking batter's team. The percentile method bootstrap was used to calculate confidence intervals for statistics representing differences in the mean distributions of two batting statistics between groups. Batters in the treatment group (hot streak active) showed statistically significant improvements in hitting performance, as compared against the control. Mean for the treatment group was found to be to percentage points higher during hot streaks (mean difference increased points), while the batting heat index introduced here was observed to increase by points. For each performance statistic, the null hypothesis was rejected at the significance level. We conclude that the evidence suggests the potential existence of a "statistical contagion effect". Psychological mechanisms essential to the empirical results are suggested, as several studies from the scientific literature lend credence to contagious phenomena in sports. Causal inference from these results is difficult, but we suggest and discuss several latent variables that may contribute to the observed results, and offer possible directions for future research.

vanadium redox flow battery Guanjie Wei, Jianguo Liu, Chuanwei Yan* State Key Laboratory for Corrosion and Protection, Institute of Metal Research, Chinese Academy of Sciences 62 Wencui Road, Shenyang, 110016, China Abstract: Polyacrylonitrile carbon nonwoven web consisting of 100 200 nm ultrafine fibers has be developed by electrospinning and subsequent carbonization process at 1000 C for different times. The surface morphology, composition, structure, and electrical conductivity of the carbon nanofibers as well as the electrochemical properties of the web toward vanadium redox couples have been characterized. As shown in Fig. 1, with the increasing of carbonization time, the reversibility of the vanadium redox couples on the electrospun carbon web (ECW) is enhanced greatly. However, as the carbonization time increases up to 120 min, the reversibility does not promote further and the hydrogen evolution is facilitated. The excellent performance of the carbon web may attribute to the conversion of fibers surface carbon structure and the improvement of electrical conductivity. Due to the good electrochemical activity and freestanding 3-dimensional structure, the ECW holds high promise for the practical application of vanadium redox flow battery as electrode materials.

Electromyography (EMG) signals have been extensively used to capture facial muscle movements while speaking since they are one of the most closely related bio-signals generated during speech production. In this work, we focus on speech acoustics to EMG prediction. We present a comparative study of ten different EMG signal-based features including Time Domain (TD) features existing in the literature to examine their effectiveness in speech acoustics to EMG inverse (AEI) mapping. We propose a novel feature based on the Hilbert envelope of the filtered EMG signal. The raw EMG signal is reconstructed from these features as well. For the AEI mapping, we use a bi-directional long short-term memory (BLSTM) network in a session-dependent manner. To estimate the raw EMG signal from the EMG features, we use a CNN-BLSTM model comprising of a convolution neural network (CNN) followed by BLSTM layers. AEI mapping performance using the BLSTM network reveals that the Hilbert envelope based feature is predicted from speech with the highest accuracy, among all the features. Therefore, it could be the most representative feature of the underlying muscle activation during speech production. The proposed Hilbert envelope feature, when used together with the existing TD features, improves the raw EMG signal reconstruction performance compared to using the TD features alone.

Synthetic Time Series Generation (TSG) is crucial in a range of applications, including data augmentation, anomaly detection, and privacy preservation. Although significant strides have been made in this field, existing methods exhibit three key limitations: (1) They often benchmark against similar model types, constraining a holistic view of performance capabilities. (2) The use of specialized synthetic and private datasets introduces biases and hampers generalizability. (3) Ambiguous evaluation measures, often tied to custom networks or downstream tasks, hinder consistent and fair comparison. To overcome these limitations, we introduce \textsf{TSGBench}, the inaugural TSG Benchmark, designed for a unified and comprehensive assessment of TSG methods. It comprises three modules: (1) a curated collection of publicly available, real-world datasets tailored for TSG, together with a standardized preprocessing pipeline; (2) a comprehensive evaluation measures suite including vanilla measures, new distance-based assessments, and visualization tools; (3) a pioneering generalization test rooted in Domain Adaptation (DA), compatible with all methods. We have conducted extensive experiments across ten real-world datasets from diverse domains, utilizing ten advanced TSG methods and twelve evaluation measures, all gauged through \textsf{TSGBench}. The results highlight its remarkable efficacy and consistency. More importantly, \textsf{TSGBench} delivers a statistical breakdown of method rankings, illuminating performance variations across different datasets and measures, and offering nuanced insights into the effectiveness of each method.


The Federal Motor Carriers Safety Administration (FMCSA) has set a goal of reducing truck related fatalities by 50% by 20 10. Achieving this goal is a formidable task requiring everyone involved in truck safety to examine his or her role as part of a coordinated effort. To this end we wish to examine the roles played by design professionals and human factors professionals in designing, implementing and evaluating advanced safety systems. Many advanced safety systems are under development and a few have been commercialized. It is clear that soon available truck options will include radar-based collision warning systems, driver fatigue monitors, rollover sensors, etc. In addition, many advanced communications systems are being proposed. The possibilities range from hands free cellular telephones to full Internet access on a head-up display. The potential for these communications systems to reduce safety by diverting drivers' attention has been well documented. This brave new world of advanced technology coupled with the goal set by FMCSA is indeed formidable new challenges to the human factors and design communities who have been historically responsible for the driver interfaces associated with these systems.


Graph bisection problems are important for partitioning data across processors in a parallel computer. Both graph bisection and the graph bisection with preferences are NP-hard problems. The traditional relaxation of graph bisection corresponds to the solution of an eigenproblem ( Lx = μx). Another approach to solve the graph bisection problem is to use semidefinite programming. Semidefinite programming has recently been used as a powerful approach to approximating NP-hard combinatorial problems. Such a hard combinatorial problem is the problem of graph partitioning or recursive graph bisection with or without preferences. While they are not known to be polynomial time in general, there are convex optimization problems and reasonably efficient algorithms are known to solve them. Thus we can expect to obtain a good suboptimal graph partition by solving a suitable semidefinite programming relaxation. Graph bisection with preferences is related to the standard graph bisection, and one possible relaxation of graph bisection with preferences corresponds to solving an extended eigenproblem (Lx = μx + g). In this thesis, we have developed subspace algorithms for semidefinite programming applied to the graph bisection. We also developed a subspace algorithm for the extended eigenproblem, and semidefinite programming relaxation for the graph bisection with preferences problem.

--During the Covid 19 pandemic, the world of education changed completely. Previously learning was done face-to-face in class or offline, but during the pandemic it was done online. One of them is learning Japanese especially speaking skills by online . One of the materials for speaking skills is presentation in Japanese. The topic of the presentation was "Pandemic of Covid 19". On this topic, students use the Gairaigo Japanese language vocabulary. This is due to lack of Japanese vocabulary knowledge related to covid 19. Gairaigo is an absorption word from a foreign language in Japanese, especially from Western European languages and does not include vocabulary from Chinese. The word uptake is already commonly used in daily life as is the original Japanese vocabulary. Therefore the purpose of this study is to determine the meaning of the equivalent gairaigo in Japanese. The research method is descriptive method that describes the equivalent of gairaigo associated with covid 19 with Japanese. Data collection techniques used are listening and note technique. Researchers watched the video presentation and noted the object of research in the form of gairaigo associated with covid 19. The results of the study, were found gairaigo from English and Indonesian.

Formal parotidectomy was undertaken in 271 patients by one surgeon over 11 years. Forty patients were treated for malignant salivary tumours (nine were recurrent). Low grade tumours (45 per cent) were treated by surgery alone, untreated high‐grade tumours (55 per cent) by surgery and radiotherapy, before or after operation, depending on clinical findings. The aims of surgery were to obtain tumour clearance, to preserve the facial nerve if possible, and to perform radical neck dissection for palpable malignant lymphadenopathy proven cytologically and for high‐grade tumours when intraoperative jugulodigastric lymph node biopsy confirmed metastasis. Four patients sustained facial weakness as a result of surgery. At a median of 46 months follow‐up two patients had developed local recurrence. Eleven patients with high‐grade but none with low‐grade tumours died from metastases. Patients with high‐grade lesions with facial weakness from malignant infiltration and those with lymphatic metastasis have a significantly worse prognosis than those without. Locoregional control of parotid cancers can be achieved by formal parotidectomy and selective irradiation without routine sacrifice of the facial nerve.


The main subject of this thesis is the study and designing of a lighting strike protection system in an existing building complex. In addition, the consequences of lighting strikes in buildings are studied and what someone can do to protect buildings. In order to apply the theory in practice, an existing building complex located in Cyprus, is used as a model in order to design the lighting protection system, since damages were observed during several lighting strikes the last few years. The study and the design of the protection system is made by following the national lighting strike protection rules and theory presented in existing literature.

The study and calculations of the other parts that belong to the complete lighting strike protection system are followed by the designing of the complete system in Autocad.

Moreover, a study of the transient behaviour of the Earth-termination system is done via the simulation of the building complex by using the EMTP-ATP software. It is important to mention that the phenomenon of ionization is consider as well in this step. The proposed lighting protection system as it is presented in this thesis and according to the results, can provide a reliable and safe operation of the building complex without any further damages.


Abstract : Reactions of the nido-cobaltacarborane anions (eta 5-C5H5)Co(CH3)2C2B3H4- and (eta 5-C5(CH3)5)Co(CH3)2C2B3H4(-) with HgCl2 in tetrahydrofuran give initially the unstable adduct ((eta5-C5R5)Co(CH3)2C2B3H4.HgCl2)(-) (R = H, CH3), which lose Cl- to form the isolable HgCl-bridged complexes mu-(eta 5-C5R5)Co(CH3)2C2B3H4)HgC1; the latter species undergo symmetrization to generate the bis(cobaltacarboranyl)mercury complexes mu,mu'-(eta 5-C5R5)Co(CH3)2C2B3H4)2Hg. In the cyclopentadienyl system (R = H), the formation of the mu,mu' complex is rapid, giving high yields within minutes; in contrast, the pentamethylcyclopentadienyl species reacts much more slowly, requiring days to form the mu,mu' complex in isolable quantity. Thus, the characterization of the mono (cobaltacarboranyl)mercury complex is readily achieved with the C5(CH3)5-substituted cobaltacarborane. The structural characterization of the Hg-bridged complexes is based on pulse Fourier transform 1H and 11B NMR, ir, and mass spectra, and single-crystal X-ray diffraction studies of mu-(eta 5-C5(CH3)5)Co(CH3)2C2B3H4-HgC1 and mu,mu'-((eta-C5H5)Co(CH3)2C2B3H4)2Hg. The mono(cobaltacarboranyl) complex crystallizes as a dimer with weak intermolecular Hg...Cl interactions.


A family $\cF\subseteq 2^{[n]}$ of sets is said to be $l$-trace $k$-Sperner if for any $l$-subset $L \subset [n]$ the family $\cF|_L=\{F|_L:F \in \cF\}=\{F \cap L: F \in \cF\}$ is $k$-Sperner, i.e. does not contain any chain of length $k+1$. The maximum size that an $l$-trace $k$-Sperner family $\cF \subseteq 2^{[n]}$ can have is denoted by $f(n,k,l)$. For pairs of integers $l<k$, if in a family $\cG$ every pair of sets satisfies $||G_1|-|G_2||<k-l$, then $\cG$ possesses the $(n-l)$-trace $k$-Sperner property. Among such families, the largest one is $\cF_0=\{F\in 2^{[n]}: \lfloor \frac{n-(k-l)}{2}\rfloor+1 \le |F| \le \lfloor \frac{n-(k-l)}{2}\rfloor +k-l\}$ and also $\cF'_0=\{F\in 2^{[n]}: \lfloor \frac{n-(k-l)}{2}\rfloor \le |F| \le \lfloor \frac{n-(k-l)}{2}\rfloor +k-l-1\}$ if $n-(k-l)$ is even. In an earlier paper, we proved that this is asymptotically optimal for all pair of integers $l<k$, i.e. $f(n,k,n-l)=(1+o(1))|\cF_0|$. In this paper we consider the case when $l=1$, $k\ge 2$, and prove that $f(n,k,n-1)=|\cF_0|$ provided $n$ is large enough. We also prove that the unique $(n-1)$-trace $k$-Sperner family with size $f(n,k,n-1)$ is $\cF_0$ and also $\cF'_0$ when $n+k$ is odd.


43 www.erpublication.org  Abstract— The objective of this study was to compare the performance of composite patch repaired cracked metal plate by varying the patch thickness and changing the patch as well as plate material. The finite element method (FEM) is used to compute the stress intensity factor (SIF) at the crack tip. Study shows that the application of the bonded composite patch very effectively reduces the stress intensity factor at the crack tip and hence retards or eliminates the crack propagation. As the chance of fracture is considerably reduced, the life of structure increases by almost twice of the initial.


Diverticula of the colon are pouchlike protrusions from the wall of the bowel which are classified as CONgenital and acquired. Congenital or true diverticula, of which Meckel's diverticulum is an example, are rare. Their distinguishing characteristic is that the wall of the sac contains all the normal coats of the bowel, from which the diverticulum originates. False or acquired diverticula, with which this paper is concerned, are of much more common occurrence, and their distinguishing characteristic is that the pouch is made up of mucosa and serosa; the muscular layers are absent. These outpouchings of the colon have been a subject of discussion for a century and a half. The condition was formerly looked on as of rare occurrence, but now it is commonly encountered. Very little has been added to Cruveilhier's1account, which was published in 1849. We hope, herewith, to make a small contribution. SPECIAL VALUE OF


Some people wonder whether there are witches, others believe that there are some, and many think there are none. All of them raise hard issues about meaning and propositional attitudes. Suppose, for example, that there are no witches. Then it seems the term 'witch' refers to nothing. So, plausibly, the word 'witch' means nothing. Hence, sentences that contain the term 'witch', such as 'There are no witches', say nothing. Therefore, a person who sincerely utters 'There are no witches' says nothing, and so says nothing that she believes. Similarly, for a person who utters 'There are witches'. Likewise, the sentence 'Are there any witches?' expresses nothing, and so a person who sincerely utters it asks nothing that she is wondering about. Therefore, the attitude ascriptions 'Some people wonder whether there are witches' and 'Some people think that there are no witches' say nothing, and so are untrue. But surely these attitude ascriptions are meaningful and true, even if there are no witches.


The new power grid puts forward higher and higher requirements for the insulation performance of power equipment. ZnO/LDPE composite has potential application value in high voltage transmission in China. With the wide application of ZnO/LDPE Composites, the study of the conductivity characteristics of the composites is helpful to further understand the conductive principle and application scope, and provide theoretical basis for reasonable use and modification.In this paper, the inorganic/polymer composites with nano ZnO as inorganic filler and low density polyethylene (LDPE) as matrix were prepared by double roll mill, and the effect of test temperature on the conductivity of the nonlinear composites was studied.


ABSTRACT The goal of social research is to discover, understand, and communicate truth about people in society. The dimensions surrounding this goal are the nature of truth and how one knows what truth is. The dominant paradigm that has surrounded social science, and particularly the study of leisure, has been positivism. Today, a number of researchers are questioning the dominant positivist assumptions that have been guiding their lives and research. In leisure research, a revolution is quietly beginning as leisure researchers are suggesting that new questions need to be asked and new methods employed to better understand leisure behavior. A new world of understanding and study awaits leisure researchers if leisure reality is viewed through a prism that reflects expanding paradigmatic and methodological choices.


Hemoglobinopathies are very common in Greece, the incidence of beta-thalassemia trait being 8% and that of sickle cell trait ranging from 1 to 32% in various districts. In Greek populations, sickle cell disease (SCD) is mainly represented by S-beta thalassemia.


A spark plug having a capacitor formed therein and a semi-surface gap, wherein the capacitor permits a high-impulse discharge to occur across the semi-surface gap and the pronounced effects of the Lorentz force, due to the high voltage and high current discharge, cause the spark to project axially away from the end of the spark plug.

The well known along track resolution loss in S A R ocean wave image specIra is investigated comparing simulations based on Hasselmann's nonlinear integral nansform and measurements from the NORCSEXS8 experiment. In the literature, the resolution loss has often been modeled as a lowpass fdter process, described by the rms azimuth shift width ox, acting within a quasilinear S A R transformation. Estimates from real data of ox, as a function of the range-to-platform velocity (R/V) and incidence angle, are compared to Hasselmann's new nonlinear spectral transformation and the widely used quasilinear model. Simulations correlated with real wave data show that the quasilinear model, with this dataset and with contributions to ox from the entire spectrum, overestimates ox with roughly 3040%. The conformity between Hasselmann's model and real data is however excellent. The numerics also indicate that the nonlinearity degree in Hasselmann's transform is explicitly related to the surface truth parameters significant waveheight and peak wavelength whcreas thc spectral bandwidth, including thc subresolution part of the Ocean wave spectrum, seems to be of minor importance. It is also shown that the resultant smearing can not (due to imaging nonlinearities) explicitly be separated from the coherent linear velocity bunching part of the transform.


T HE PROBLEMS attending the failure to hear normally can hardly be understood without some grasp of what normal hearing is like. This understanding must go beyond the physical characteristics of sound and beyond the organic reception of auditory stimuli. It must include an awareness of the psychological and social effects of audition. Apparently it is difficult to establish the concept that hearing may differ not only in degree but also in kind. Every clinician concerned with hearing is familiar with reports that a patient can hear "real well" and yet fails to understand much of what is said to him. Most of us know of persons who literally can hear a pin drop but still have difficulty in oral communication. Such instances, along with observation and study of persons with severe loss of hearing, point to the important fact that deafness brings about a qualitative as well as a quantitative change in the total pattern of sensory perception (1).


A rigorous field analysis is given for the problem of diffraction by a loaded aperture formed of two perfectly conducting half planes and excited by an electric line current. The aperture is loaded with a dielectric cylinder whose axis coincides with the intersection of the extension of the two half planes. The two media outside the dielectric cylinder which are spearated by the two half planes are, in general, dielectric materials. The edges of the two half planes are parallel to the axis of the cylinder, however their surfaces can be in two different planes


Complementary and integrative health (CIH) providers, such as chiropractors and naturopathic doctors, have been an underutilized public health asset in the response to the COVID-19 pandemic. This article seeks to inform how they can be better integrated into future responses to public health emergencies. The authors convened an expert panel of ten CIH and public health practitioners and researchers for a daylong discussion of how the CIH workforce could be better mobilized during future crises. In this article, the authors summarize the key barriers identified in the discussion and make recommendations on how they can be overcome.


The intent of this program was to establish an understanding of the role of solid-state radiolysis, secondary electron interactions, charge transfer dynamics and the general effect of heterogeneous solids (interfaces and particulate surface chemistry) on tank waste radiation processes. Specifically, there was a need to understand the role of interfaces and solids in the generation of noxious gases and the mechanisms of organic compound degradation.


Previous research on steady-state visual evoked potential(SSVEP) and inverse EEG shows amplitude and spatial differences of visual evoked response to steady-state visual stimulus of different frequencies.The fMRI experiments were employed to study the frequency dependence of visual evoked response in this paper.The experiments were designed according to SSVEP results,5 volunteers were scanned on MR scanner while they were presented visual stimulus of several frequencies to acquire fMRI data.Results of pre-processing and statistical analysis by SPM show unilateral dominance of response regions which displays the dominance representation in steady-state visual response.Possibility of relationship between the unilateral dominance and stimulus properties is discussed,as well as the perspectives of further research and application.


Copper-exchanged SAPO-34 (Cu-SAPO-34) provides excellent catalytic activity and hydrothermal stability in the selective catalytic reduction (SCR) of NOx by using NH3 as a reductant. We find that the 6-membered ring (6MR) site is the most energetically favorable for a Cu+ ion while the 8-membered ring (8MR) sites are less favorable by about 0.5 eV with respect to the 6MR site in Cu-SAPO-34. Upon adsorption of molecular species (H2O, O, OH, O2), the energy differences between Cu in the 8MR and 6MR sites decreases and almost disappears. Further, a thermodynamic phase diagram study shows that a Cu+ ion bound to a single H2O molecule is the most stable species at low oxygen potential values while a Cu2+ ion bound to 2 OH species is more stable when the oxygen chemical potential is sufficiently high. By comparing Cu K-edge XANES between Cu-SSZ-13 and Cu-SAPO-34 with Cu in different oxidation states,


High concentrations of ozone along the coastline of Lake Michigan are a persistent air quality management challenge. Complementing observations during the 2017 Lake Michigan Ozone Study (LMOS 2017), WRF‐Chem modeling was used to quantify sensitivity of modeled ozone (O3) to anthropogenic nitrogen oxides (NOx) and volatile organic compound (VOC) emissions, including to changes in volatile chemical product (VCP). The daily maximum 8 hr average (MDA8) over the high ozone region of Lake Michigan decreased by 2.7 ppb with exclusion of VCP from the inventory, and was sensitive to both NOx and VOC changes, with greater sensitivity to NOx. Close to urban centers, MDA8 ozone was VOC‐sensitive. Clusters of coastal receptor sites were identified based on similarity in response to emission perturbations, with most clusters being NOx‐sensitive and NOx‐sensitivity increasing with distance from major emission sources. The 2 June 2017 ozone event, which has received considerable focus, is shown to be atypical due to unusually strong and spatially extended VOC‐sensitive behavior. WRF‐Chem integrated reaction rate analysis was used to compute radical termination rates due to NOx (LNOx) and to radical‐radical reactions (LROx). LROx/LNOx and formaldehyde to NO2 ratio (FNR) were shown to be predictive of modeled MDA8 ozone sensitivity, but with variation in predictive power as a function of time of day, which has implications for air quality management use of FNR from geostationary satellites.


The present work reports some experimental results on the electrical properties of commercial Gallium Nitride blue light emitting diode (GaN blue LED). Many instruments have been used in this study to make different kinds of measurements. For example, Keithley 238 high current measure unit, Boonton 7200 capacitance meter, and Wayne Kerr 6440 precision component analyzer (within frequency range from 20 Hz to 3 MHz). In this paper, the electrical properties of the selected sample are studied in details under wide range of temperatures (100–440) K. Analysis and discussion for the obtained results are adopted.


Dr Karamat et al1 raise the interesting hypothesis that increased vascular smooth muscle reactivity in subjects of African ancestry may be related to greater activity of the enzyme creatine kinase in vascular muscle cells. Our study was not designed to elucidate the biochemical mechanisms of ethnic differences in vascular reactivity, but it is nevertheless interesting to consider our findings with the creatine kinase hypothesis in mind. If increased creatine kinase activity …


This paper offers a critique and a reformulation of Brian Fry and Richard Winters's policy output study published in this Review June, 1970. Fry and Winters focused on the redistributive impact of public policy in the states. After devising a "redistribution ratio" that involves allocating state revenue burdens and expenditure benefits to families across income classes, they developed a model to explain the variance of this ratio from state to state. In contrast to the findings of many earlier policy output studies, they hypothesized that political variables would have more explanatory power than socioeconomic variables. Unfortunately some methodological shortcomings detract from the potential value of the Fry and Winters study. In this paper, alternative methodologies are used to reformulate a redistribution ratio for each state, and the recalculated ratios are found to vary significantly from those obtained by Fry and Winters. The shortcomings of the Fry and Winters explanatory model are discussed. Despite these shortcomings, however, the regression analysis employed by Fry and Winters is repeated using the reformulated redistribution ratios in order to test the impact of this reformulation. Again the results obtained in this paper vary substantially from those of Fry and Winters.


Falls are one of the most frequent complications on geriatric rehabilitation wards. In addition to having adverse consequences for patients, falls also result in prolonged hospitalisation and increased healthcare costs. Therefore, identification of risk factors and development of successful falls prevention strategies targeted at this population are essential. The aim of this study is to identify predisposing or situational risk factors contributing to falls in older adults completing post-acute inpatient rehabilitation.

 Retrospective review of all inpatient falls on two geriatric rehabilitation units over a one year period identified from incident forms. Chi-squared test was used to calculate differences between fallers and non-fallers.

 One in five patients admitted to the unit suffered a fall (average age 81, 52% male) with a total of 95 falls involving 56 patients. Of these, only 77% (n = 43) were identified as high risk on falls screening. 61% (n = 34) had one fall and 39% (n = 22) had two or more falls. Nearly one in three (n = 15) falls resulted in injury. More falls occurred in the single bedded unit (14.8 per 1,000 bed-days) as compared to the multi-bedded unit (6.8 per 1,000 bed days). Use of a Zimmer frame or rollator was associated with more falls than use of other mobility aids. Fallers tended to have a previous history of falls (75%, n = 42) and polypharmacy (average 10 medications). Delirium and dementia were present in one third of fallers. Falls were associated with a higher risk of discharge to long-term care, with 70% of fallers discharged home compared to 89% of non-fallers (p = 0.0006).

 Previous falls, single room occupancy, polypharmacy and a medium level of dependency when mobilizing were identified as predictors of falls in our review. Nearly a quarter of fallers were not identified as high falls risk on screening further questioning the utility of falls risk screening assessments.


The present article deals with the notion of representativeness in corpus linguistics. It turns out that there are no exact methods for assessing representativeness, and for this reason the representativeness of a corpus is nothing more than a tacit agreement between the creators of a corpus and its users. The General Internet Corpus of Russian (GICR) which is presently under development tries to make such an agreement explicit. It encourages its uses to study register variation in the Russian language of the Internet. The linguistic community will be able to use a research tool to study different segments of the Web and to create subcorpora using automatically extracted metadata. As for June 2013, GICR contains two segments of the Russian Web, namely the blog platform LiveJournal.com and the "Magazine Reading Room" (http://magazines.russ.ru/). More segments will be added soon.


The aim of the paper is the application of MSC Adams/View for kinematic analysis of motion of a mass point in a curve with consideration and without consideration of resistive forces. The first section describes the program Adams and its modules Adams/View, work with this module and its basic operation. In the following section there is solved an inclined throw of a mass point with and without resistance using numerical methods. Subsequently, this work deals with assembling of the models in Adams/View, running the simulations, plotting the trajectory, which shows the distance travelled and with creation of a table of parameters for easier and especially quicker change of model properties. Finally, the work presents the results with graphic display of parameters such as speed, distance and acceleration.


Permittivity reconstruction of head tissues has an essential role in the application of microwave imaging for brain stroke diagnostics. In this paper, we propose a deep learning enhanced microwave imaging approach for estimating permittivities of tissues inside the head assuming that only the outer boundary of the head is known. The approach first retrieves the inner domain boundaries and then determines the permittivity of each domain. The first task is performed by a U-Net neural network trained to predict the inner boundaries based on the qualitative images obtained using the first order solution computed via truncated singular value decomposition. Then, the permittivities of the domains inside the head are iteratively estimated using the distorted Born iterative method. An assessment of the approach with a simplified but realistic head model consisting of two homogeneous tissues is provided.


This study aims to investigate the adoption behavior of artificial intelligence applications in the context of Pakistan by developing an extended model of technology acceptance incorporate behavioral beliefs (perceived usefulness and perceived ease of use). Further, the influence of the individualism/collectivism (IND) cultural dimension is investigated using the moderating framework. A cross-sectional survey method was used to collect data sample from 328 individuals in Pakistan. Hierarchical multiple regression analysis was employed to examine the data. The findings confirmed the hypothesized associations and indicated that the proposed model provided a satisfactory fit to the data. The findings also revealed that cultural factors moderated the strength of these prospective relationships. Non-Western cultural settings can benefit from this research. The study offers several theoretical and practical implications.


The laser treated surface method is a novel way to mitigate electron cloud in high-energy and high-intensity particle accelerators. Aluminum alloy is a common and important material used in the vacuum system construction of particle accelerators. The influences of laser parameters, such as scanning speed and average laser power on the secondary electron yield (SEY) and surface morphology of laser processed aluminum alloy samples, were studied and explored in this paper. The as-received laser processed aluminum alloy surfaces with SEY less than 1 were obtained. The surface composition and topography were tested by the X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and laser scanning confocal microscopy (LSCM). The XPS results revealed that the surface of as-received laser processed aluminum alloys consists of aluminum oxide layer and intermetallic aluminum. The LSCM and SEM results show that the selection of appropriate laser parameters and hatched patterns was ascertained by the surface topography of the sample to obtain low-SEY surface.


Abstract The details of robust computational and novel semiempirical methodologies that were developed and tested at the University of Missouri Research Reactor (MURR) to accurately determine the possibility of a "hot" startup and the estimated critical position (ECP) of the control rods following an unplanned shutdown are presented. The computations, based on a modified coupled MCNP5-ORIGEN2 code system and using ENDF/B-VII.0 and TENDL-2013 nuclear data sets, accurately simulate the MURR core operational histories while predicting the critical rod positions within ±0.001 Δk/k of experimental critical data. In this study, using the coupled MCNP5-ORIGEN2 computations, various core-specific parameters were methodically characterized and were adapted into a semiempirical formulation better suited for practical reactor operations. The predictive capabilities of these novel semiempirical approaches regarding core criticality and ECPs required utilizing, for the first time, the net transient response of the negative reactivity worth for necessary fission product poisons including 135mXe and several others. Calculation-to-experiment deviations in hot-startup criticals and the corresponding control rod positions are shown to be less than ±0.03% Δk/k and ±1% difference in relative rod position, respectively.
