This paper focuses on the methodology of analysis for monitoring farmers' needs and priorities of actions, in order to define a rational and efficient intervention program, at a regional scale. The approach adopted in this research is based on the Public Choice theoretical approach, and we adopted the focus group methodology to collect descriptive information, that we processed through the content analysis methodology.


Multicrystalline silicon wafers, widely used in commercial photovoltaic cell production, traditionally give much poorer cell performance than monocrystalline wafers (the previously highest performance laboratory devices have solar energy conversion efficiencies of 18.6% and 24.0%, respectively). A substantially improved efficiency for a multicrystalline silicon solar cell of 19.8% is reported together with an incremental improvement in monocrystalline cell efficiency to 24.4%. The improved multicrystalline cell performance results from enshrouding cell surfaces in thermally grown oxide to reduce their detrimental electronic activity and from isotropic etching to form an hexagonally symmetric "honeycomb" surface texture. This texture reduces reflection loss as well as substantially increasing the cell's effective optical thickness by causing light to be trapped within the cell by total internal reflection.

The hog cycle was one of the earliest recognized economic cycles in Taiwan. A cycle is a pattern that some variables follow which repeats itself regularly over a period of time. A true cycle is self-energizing and not the result of chance factors. The length of a cycle is the time from one peak to the next or from one trough to the next, and is usually related to the time required to produce a new generation (Tomek and Robinson, 1972). The time lags involved in the hog production process and the interrelationships among price, pig crop, and slaughter contribute to the development of the cycle. There are two ways to analyze cyclical supply hog production. One is based on the cobweb model; the usefulness of this approach has been confirmed in the works of Waugh (1964), . Nerlove (1958), and Harlow (1962). Another approach is based on different forms of harmonic models. Both models explain commodity supply and require careful interpretation of a timeseries graph of the data. Once an appropriate period is selected, the right length of expectation of farmers can be fitted in a cobweb model and a harmonie model. These two models can be estimated using regression methods to determine the amplitudes of the cyclical components. The cobweb model is perhaps the classic illustration of a recursive sytem. The simplest cobweb model, provided by Ezekiel


This article discusses the effect of the possible changes in the gravitational constant on the precession of Mercury's perihelion. The analysis results show that based on the current more accurate theoretical calculations of relativity, if the correction of the change of the gravitational constant is added, the theoretical calculation results can be improved to a certain extent to make them consistent with the observation results.


This dissertation deals with the design of high-speed, bilinear algorithms for digital signal processing applications that are especially suited for implementation on dedicated hardware platforms. Bilinear algorithms exhibit a high degree of concurrency as all multiplication operations involved are independent of each other and can be computed at the same time. Consequently, the critical path delay for hardware implementations of these algorithms is very low. The algorithms developed here have other important properties such as a well defined recursive structure, modularity and low complexity. The first two properties are important for efficient mapping of the algorithm onto hardware and the last property helps in reducing hardware cost. Bilinear algorithms also have the advantage that two or more smaller algorithms can be used to obtain a larger, composite algorithm.
This dissertation develops bilinear algorithms for the discrete Fourier transform (DFT) and the discrete cosine transform (DCT). We use concepts of group theory to identify computational blocks within the transform kernel that can be transformed into cyclic, skew-cyclic or Hankel structures. By combining bilinear algorithms for these structures we get the required bilinear algorithm of the transform. We deal with transform lengths ranging from 2 n to prime lengths and even lengths that are powers of odd primes. The algorithms thus obtained have a recursive structure and computational blocks developed for smaller algorithms can be used in the computation of larger algorithms of related lengths. To verify the concepts developed here, the DFT algorithms (of lengths 2n and 3 n) were synthesized using Mentor Graphics synthesis tools and laid out as an ASIC. A comparison of these algorithms against the fast Fourier transform (FFT) and the more recently developed quick Fourier transform (QFT) shows that, as expected, our algorithms perform better than these algorithms. For a 64-point DFT, the bilinear algorithm is twice as fast as the QFT and three times faster than the FFT. Further, its area complexity is half that of the QFT and about a fourth of the FFT complexity.


The crack can occur in any bone ofour body. Broken bone is a bone condition that endured a breakdown of bone trustworthiness. The Fracture can't recognize effortlessly by the bare eye, so it is found in the x-beam images. The motivation behind this task is to find the precise territory where the bone fracture happens utilizing X-Ray Bone Fracture Detection by Canny Edge Detection Method. Shrewd Edge Detection technique is an ideal edge identification calculation on deciding the finish of a line with alterable limit and less error rate. The reproduction results have indicated how canny edge detection can help decide area of breaks in x-beam images. In the base paper, the cracked bit is chosen physically to defeat this downside, the proposed technique identify the bone fracture consequently and furthermore it quantifies the parameter like length of the crack, profundity of the fracture and the situation of the crack as for even and vertical pivot. The outcome demonstrates that the proposed technique for crack identification is better. The outcomes demonstrate that calculation is 91% exact and effective


Laboratory studies involving surface waves usually require the use of absorbers at some boundaries of the test facility to prevent objectionable reflections of the test waves. Such absorbers frequently consist of sloping beaches with or without a layer of permeable material. These are sometimes used in conjunction with other devices which absorb part of the wave energy. If sufficient space is available, a long absorber with a low surface slope can be used, resulting in very low reflections. However, space limitations sometimes necessitate the use of an absorber of minimum length with a steeper surface slope. In such cases permeable materials are highly beneficial to assist in absorbing the wave energy.


This communication presents a wideband circularly polarized (CP) 2 × 2 patch array using a sequential-phase feeding network. By combining three operating modes, both axial ratio (AR) and impedance bandwidths are enhanced and wider than those of previous published sequential-fed single-layer patch arrays. These three CP operating modes are tuned and matched by optimizing the truncated corners of patch elements and the sequential-phase feeding network. A prototype of the proposed patch array is built to validate the design experimentally. The measured -10-dB impedance bandwidth is 1.03 GHz (5.20-6.23 GHz), and the measured 3-dB AR bandwidth is 0.7 GHz (5.25-5.95 GHz), or 12.7% corresponding to the center frequency of 5.5 GHz. The measured peak gain is about 12 dBic and the gain variation is less than 3 dB within the AR bandwidth.


Pb–Zn smelting is a major cause of heavy metal(loid) contaminations in soils. We collected data on heavy metal(loid)s in the soils near Pb–Zn smelteries globally from 54 peer-reviewed reports to study the metals' distribution, pollution index, and potential ecological and health risks. We observed that 90% of the studied Pb–Zn smelteries were distributed in Asia and Europe. Heavy metal(loid)s were mainly deposited within a 2 km distance to the smelteries, with mean concentrations (mg/kg) of 208.3 for As, 26.6 for Cd, 191.8 for Cu, 4192.6 for Pb, and 4187.7 for Zn, respectively. Cd and Pb concentrations in the soil exceeded their corresponding upper continental crust values several hundred folds, suggesting severe contamination. The smelting area had the highest heavy metal(loid) contamination in soil, followed by the forest land, farmland, and living area. Compared with the soil environmental standard values from various countries, As, Cd, Pb, and Zn were considered priority pollutants for protecting the ecosystem and human health. Likewise, As, Cd, and Pb were suggested as the priority pollutants for protecting groundwater safety. The potential ecological and health risks of heavy metal(loid)s in the soil within 2 km of Pb–Zn smelteries were severe and should be of concern.

The invention relates to an embedded two-layer harmonic drive reducing gear, which comprises a wave generator. The output end of the wave generator is provided with an input shaft, and a cam is arranged outside the input shaft. The embedded two-layer harmonic drive reducing gear is characterized in that inner-layer flexible bearings are distributed outside the cam; and an inner-layer flexible wheel is sleeved outside the inner-layer flexible bearings. Furthermore, an inner-layer steel wheel is sleeved outside the inner-layer flexible wheel, and outer-layer flexible bearings are sleeved outside the inner-layer steel wheel. Meanwhile, an outer-layer flexible wheel is sleeved outside the outer-layer flexible bearings, and an outer-layer steel wheel is sleeved outside the outer-layer flexible wheel. Therefore, double-layer harmonic waves are realized, and can achieve a higher gear ratio than the conventional single-layer harmonic waves. Meanwhile, due to the elliptical fit design, the accuracy and the efficiency are higher than single harmonic waves. The huge torque output can be realized; and in addition, the embedded two-layer harmonic drive reducing gear is precise in structure, small in size and compact in structure, easily adopts to different installation places and deserves promotion and application.


The hydrogel used as the material of soften cornea contact lens is synthesized by copolymerization. It adopt N-vinylpyrrolidone (NVP), methacrylic acid-β-hydroxyethl methacrylate (HEMA) and KH570 as monomers, with Bis as crosslinker and azobis iso butyro nitrile(AIBN) as initiator. Cavity-membrane measuring method is adopted to study the sodium penetration capability. It is found that the penetration capability increases with the increase of NVP in the copolymer hydrogel. The sodium penetration capability increases with the increase of KH570 less than 15%. However, 15%~25% content of KH570 would decrease penetration capability. The increase of crosslinker content would also decrease the sodium penetration capability when its content is not more than 0.7%.


We briefly review the physics of gate operations between quantum dot spin-qubits and analyze the dynamics of quantum entanglement in such processes. The indistinguishable character of the electrons whose spins realize the qubits gives rise to further entanglement-like quantum correlations that go beyond simple antisymmetrization effects. We also summarize further recent results concerning this type of quantum correlations of indistinguishable particles. Finally we discuss decoherence properties of spin-qubits when coupled to surrounding nuclear spins in a semiconductor nanostructure

This study investigated, in detail, the characteristics of the Late Triassic fine-grained sediments in the third member of the Xujiahe Formation (Xu-3 Member), in the Western Sichuan Depression, and the paleoenvironmental evolution during their deposition through petrological interpretation, mineralogical composition characterization, and element geochemical analysis. According to the mineralogical composition, the Xu-3 Member can be divided into two petrological types, namely clayey fine-grained felsic sedimentary rocks and lime fine-grained felsic sedimentary rocks. The main mineral components are siliceous, clay, and carbonate minerals. Through the cluster analysis of major elements, all samples could be divided into two types with different major elemental characteristics. Trace elements exhibited distinct Sr depletion, relative enrichment of large ion lithophile elements, and high field strength elements. Two REE enrichment patterns were observed, which could be attributed to differences in the provenance area and tectonic background. The paleoclimate of the sedimentary area was warm and humid, but it was hotter and drier in the southern and central parts of the depression. The change trend of paleo-productivity was consistent with the paleoclimate. The waters in the sedimentary environment were mainly brackish water to saline water, with fresh water in the southern part of the depression. The paleo-redox conditions of the waters were mainly sub-oxidation to sub-reduction, but the southern part of the depression was more oxidative. The provenance area experienced a moderate degree of chemical weathering under a warm and humid paleoclimate, same as the depositional area. However, the depositional environments differed between the northern and south-central parts of the depression.


Ammonia (NH3) volatilization may be an important part of the nitrogen (N) budget in swine-waste-amended farming systems. Ammonia volatilization was quantified from three circular bermudagrass (Cynodon dactylon, [L.] pers) plots receiving three split swine (Sus scrofa domestica) effluent applications during the 1998, 1999, and 2000 growing seasons. Plots were maintained over the course of the study and used to characterize relative volatilization patterns following land-application of effluent. Swine effluent was applied based on total phosphorus concentration to approximate 9 kg ha−1 application−1. Based on the total amount of N supplied via swine effluent, plots were supplemented with ammonium nitrate to meet bermudagrass N requirements of 112 kg ha−1 application−1. Immediately following waste treatments NH3 volatilization rates were quantified using a passive field scale technique, which consisted of a rotating mast and five oxalic acid charged tubes located at the center of each plot. Peak volatilization rates ranged from approximately 3 to 8 kg NH3 ha−1 day−1, and total N losses were between 8 to 31% of N applied as swine effluent supplemented with ammonium nitrate. Ammonia volatilization losses associated with land-applied swine effluent were greatest immediately following application and quickly diminished to background volatilization rates.

Elevated left atrial (LA) pressure is a pathophysiologic hallmark of heart failure with preserved ejection fraction (HFpEF). Chronically elevated LA pressure leads to LA enlargement, which may impair LA function and increase pulmonary pressures. We sought to evaluate the relationship between LA volume and pulmonary arterial haemodynamics in patients with HFpEF.


Increasing presence of non-linear and unbalance loads in electrical networks leads to severely distorted and unbalance voltage/current signals. Accordingly, the estimation of amplitudes and phase angles of symmetrical components are required in many power system applications, e.g. digital protection and power quality monitoring. We propose a complex Adaline based approach for fast and accurate sequences estimation. In this approach, three-phase signals are firstly simplified to a complex signal through the alphabeta transformation. Then, the transformed complex signal is fed to a complex Adaline processing unit to estimate embedded positive and negative sequences. This method directly estimates sequences of all individual harmonic components with low computational burden and high estimation speed, which is requested for on-line hardware implementation. Finally, two comparative case studies are conducted on the MATLAB and PSCAD/EMTDC to investigate the proposed method performance and compare it with another successful method, multi-output Adaline.


The Compact Muon Solenoid (CMS) is one of the general-purpose detectors to be provided for the LHC project at CERN. The design field of the CMS superconducting magnet is 4 T, the magnetic length is 12.5 m and the free bore is 6 m. The CMS coil consists of five independent modules each containing four winding layers. Each winding layer is composed of a single length of aluminum stabilized and aluminum alloy reinforced conductor. Each of the four conductor lengths within a module will be electrically joined after winding is completed, and each of the five modules will be connected to the magnet bus bars during module assembly. Due to the large dimensions of the conductor and to the high current it carries, the conductor joints are sources of substantial and nontrivial joule heating during nonsteady state operation of the magnet. In addition to steady-state conditions, three transient conditions have been analyzed. The first is related to the current diffusion during a magnet transient that results in a time dependent joint resistance. The second is the current induced in a joint during a transient. The third is connected to the joint protection in case of quench. A complete analysis of the joint behavior is reported.


• What are some ways to evaluate our research question: "Does a resident-driven conference increase resident engagement and leadership in safety events?" • Is there a way to retrospectively look back at this past 1.5 years of conferences and interpret impact with out a pre-survey? • Would this project be more successful if looked at from an educational quality improvement standpoint? • How and where could this type of research be published?


In this work, the effect of recycling the process water (PW) of hydrothermal liquefaction (HTL) to the HTL reactor was investigated, with the objective being to recover carbon from the organic content of the PW and to develop a solvent-free process. When recycling twice the PW at 220, 240, and 265 °C, a significant increase in bio-oil production is observed at all temperatures. An extended series of recycle experiments was performed at 240 °C, showing that the bio-oil yield increased up to stationary level, after six recycles. To investigate the role of accumulated compounds as acetic acid, additional experiments were carried out with dilution and spiking of recycled PW. PW recycling not only increases bio-oil yield but also enables to reduce operating temperature (and, hence, costs) of HTL; therefore, it is an essential element in developing a solvent-free process for biocrude production from microalgae.


A femtosecond oscillator is employed to create periodic grid patterns in a commonly used polymer, poly (methyl methacrylate), PMMA. The wettability measured in terms of static water contact angle shows that the laser patterning causes an enhancement in water contact angle and the magnitude of change depends on the irradiation fluence during writing.A water droplet placed on a laser-patterned surface spreads anisotropically and exhibits different static water contact angle along different directions. Micro-Raman and Scanning Electron Microscope studies carried out on laser patterned and nonpatterned regions clearly confirm that the observed wettability change is due to physical (morphological) changes rather than chemical changes. More interestingly, the replica of the periodic laser patterned structures created on a soft polymer,polydimethylsiloxane (PDMS), via soft lithography technique exhibits superhydrophobic behaviour with a rolling-off nature for the water droplet. This is likely to find variety of applications in diverse fields ranging from passive defogging of windscreen to waterproof clothing to non-stick cookware.

Beginning in March 2019, the 996.ICU movement has signalled growing resentment among tech workers in China regarding the sector's overtime work culture. The mobilisation emerged in the context of growing discontent among employees in China's tech and Internet industry due to normalised overtime, stagnant salary and benefit growth, and health damage caused by demanding management. Still, according to this essay, the movement did not generate further solidarity because it failed to advance any structural critique, limiting itself to producing a nostalgia of the more reciprocal employment relationship of the recent past. The 996.ICU Movement in China Changing Employment Relations and Labour Agency in the Tech Industry PC: 996.ICU.


Sodmein Playa is one of the rare Pleistocene open‐air sites in the Eastern Desert of Egypt. Based on the associated stone artefact material, it could be assigned to the Middle Stone Age/Last Interglacial. However, it has not yet been possible to clarify whether the sediments at the basin originated during the Pleistocene or later during Holocene wet phases. Our integrative approach combining Optically Stimulated Luminescence chronology, and cryptotephra analysis, allows us to link the environmental archive of Sodmein Playa with the site of Sodmein Cave. Sodmein Playa indicates wetter climate conditions starting around 9 ka with a (relative) maximum around 7 ka, in line with the general framework of the Holocene Humid Period in Northeast Africa. Despite the climatic similarity, regional environmental differences can still be identified and the effective available water around Sodmein Playa is reduced. The results are well integrated into the current archaeological knowledge with the change from hunter‐gatherers to herders during the Holocene in the area. Analyses of cryptotephra reveal a wide range of source regions, including Eastern and Central Anatolian, the Azores, and the Aegean, as well as those which remain uncorrelated. A tentative correlation with the Holocene cryptotephra record from Sodmein Cave is established.


P-wave velocity measurement can be used to evaluate the rock mass quality and its soundness. Many factors influence the quality of a rock mass including the joint spacing, roughness, persistence, weathering, opening and filling. In this paper the effect of joint filling in andesite rock samples were studied using an ultrasonic instrument in laboratory. The rock samples were collected at depth of boreholes from under construction dam site. Physical and lithological properties of the samples were then determined. Also, artificial joint were made in the middle part of the samples perpendicular to their longitude axis. Regarding to natural joint infilling at site, the artificial joints were filled with silica at different thicknesses (1, 2 and 5 mm) to evaluate the effect of thickness, also joints were filled with gypsum at similar thicknesses to investigate the effect of filling type on sound velocity. The transducers were attached to the both ends of the samples while applying the ultrasonic waves. The results were plotted on graphs which show a correlation between the wave velocity and the joint infilling thickness. To evaluate the effect of joint opening on rock mass, velocity reduction ratio (VRR) was introduced. The VRR is defined as a ratio between wave velocity deviations of jointed rock to the wave velocity of intact rock sample (VRR% = V0−V1 V0 × 100). The VRR% of a jointed rock increases with increase in the joint infilling thickness and this incrasing in Gypsum infilling type is sharper than Silica infilling type.


The sound power radiated by a thin‐shelled cube is calculated from simulated acoustic velocities (equal to the normal shell velocity) using the boundary element method (BEM) [K. A. Cunefare and G. H. Koopmann, J. Vib. Acoust. 113, 387–394 (1991)]. Optimization techniques are then used to predict velocity distributions that result in the minimum output sound power. In future work, recommendations for the addition of passive noise control materials will be defined on the basis of achieving the calculated optimal velocity distribution that will result in the minimum radiated sound power. These criteria are tested on a point‐driven, thin‐shelled cube in an anechoic chamber. The normal shell velocity is measured using a laser velocimeter. Again, sound power is calculated and the optimal velocity distribution is determined using the BEM. Accuracy of power predictions, based on experimental power measurements and computational examples, as a function of frequency and vibration pattern are studied.


Minimally invasive surgeries are widely used in traumatology and orthopedics. Both the surgical technique and the instruments applied are getting better, which contributes to the improvement of functional results of patient treatment.
Aim of the study: to present a new method of minimally invasive surgery using the original guide device in the treatment of acquired valgus deformity of the first toe.
This study describes a guide device that can be applied in correcting osteotomies for Hallux Valgus. This instrument is used to install guide wires for the subsequent insertion of compression screws fixing the fragments of the first metatarsal bone. We also present a clinical case illustrating the successful use of the device described. A patient underwent minimally invasive correction of a moderately severe valgus deformity of the first toe. In the postoperative period, she was managed according to an accelerated rehabilitation protocol that included full load on the operated limb the day after osteotomy, as well as a complex of exercises to improve active movements in the foot joints. The advantages of minimally invasive surgeries in the treatment of patients with Hallux Valgus, one of which is the possibility of early rehabilitation, are discussed in the article. It has been demonstrated that minimally invasive correcting osteotomies provide better functional results compared with open surgeries. This can be explained by the development of more advanced methods of surgical treatment and new instruments.
Conclusion. The use of the presented guide device reduces surgery duration, decreases sof-tissue injury, and minimizes the radiation exposure of the surgeon and the patient.


The effect of ionic strength in standard additions and subtractions methods has been utilised for determining an unknown concentration using an ion-selective electrode without prior calibration of the electrode. In the simplest instance, only two standard additions or subtractions are required. An initial value of unknown concentration or electrode slope is first assumed to solve the equations repeatedly. This method gives greater accuracy than the methods which are used at present. The method was used to evaluate the unknown concentration and electrode slope. The blank solution has the same ionic strength as the standard solution in the two standard additions method. In the two standard subtractions method, a suitable blank solution is chosen. The effectiveness of computer iterative solution of the two standard additions method is demonstrated on a lead sample.

Vaishnavism is a traditional faction of Hinduism, differentiated from other schools by its veneration of Lord Vishnu. Besides Vishnu, Vaishnavites also worship His associated avatars, chiefly Lords Rama and Krishna, who are conceived as the original and supreme God. Vaishnavism entails worshipping of different perspectives or historical traditions, yet addressing a monotheistic God under the names of Narayana, Krishna, Vasudeva or more often "Vishnu" and their related embodiments.


Two studies compared young and older adults' production of complex syntactic structures in Russian, a morphologically rich language with free word order. A variety of measures of content, fluency, clause structure, and grammatical form were assessed from oral language samples collected from young adult Russians visiting the United States, from older adults who had recently emigrated to the United States from Russia, and from young and older Russians living in Moscow, Russia. Content and fluency in Russian were associated with Russian vocabulary knowledge and influenced by educational level and knowledge of English and other languages. The production of grammatical forms, including clause structure and word order variation, was associated with digit span, suggesting that working memory limitations affect the use of clause and word order variations in Russian.

During embryo development, embryonic gene activation (EGA) is the first critical event. We previously showed that EGA is also critical for further development in somatic cell-cloned embryos (Saeki K et al. 2004 Reprod. Fertil. Dev. 16, 157–158 abst). To show this, we reconstructed bovine embryos with bovine somatic cells transfected with chicken β-actin/firefly luciferase fusion gene (β−act/luc+) and showed that only luminescent embryos at 60 hours post-fusion (hpf) developed to the blastocyst stage. In this study, we examined the relation between the intensity of expression of the same reporter gene in embryos reconstructed with bovine β−act/luc+ fibroblasts and their subsequent development to the blastocyst stage. Bovine fibroblasts were transfected with β−act/luc+ as described earlier (Saeki K et al. 2004 Reprod. Fertil. Dev. 16, 157–158 abst). The stably transfected and cloned cells were cultured for several passages. The cells were cultured under serum starvation (0.4% FCS) for 7 days and then used as donor cells. In vitro-matured bovine oocytes derived from slaughterhouse ovaries were enucleated at 20 h post maturation. Enucleated oocytes were electrofused with the cells, and activated with a calcium ionophore and cycloheximide. The LUC+ signal (luminescence) in the embryos was detected in medium containing 500 μg mL−1 luciferin with an imaging photon counter (ARGUS 50, Hamamatsu, Japan) for 30 consecutive min at 60 hpf. The intensity of luminescence in embryos (4- to 8-cell stage) was graded as being strong (>10 × 104 pixels/embryo), intermediate (5 to 10 × 104 pixels/embryo), weak (<5 × 104 pixels/embryo), or absent. The embryos were cultured separately until 168 hpf, and examined for blastocyst development. Experiments were repeated four times, and the data were analyzed with Fisher's PLSD test following ANOVA by Stat View software (Ver. 5.0; abacus Concepts, Berkeley, CA, USA). Of 125 embryos that were reconstructed, 74 (59%) developed to the 4- to 8-cell stage at 60 hpf. The luminescence was strong in 29 (39%) of the embryos, intermediate in 12 (16%), weak in 19 (26%), and absent in 14 (19%). Blastocysts were obtained from a group of embryos that exhibited strong luminescence (10/29, 34%), but none of the embryos from the other groups developed to blastocysts. These results suggest that active gene expression in embryos reconstructed with somatic cells is important for their subsequent development. This study was supported by a Grant-in-Aid for the 21st Century COE Program of the Japan Ministry of Education, Culture, Sports, Science, and Technology, and by a grant from the Wakayama Prefecture Collaboration of Regional Entities for the Advancement of Technological Excellence of the JST.

In this letter, we proposed a Multi-Stage phase-shifting network (MSPS-Net) based on Multi-Stage Progressive Image Restoration for one-shot phase retrieval interferometry. This network generates three interferograms with specific phase shifts from interferograms recorded in a single frame excellently, metrics such as PSNR and SSIM indicate that the generated phase shift interferograms have high similarity to the real one. Further, By analyzing different types of aberrations, RMS value of error map retrieved by the proposed method is less than, which shows higher accuracy than latest phase-shifting network method built by Encoder and Decoder. All the experiment results show that our solution is available for the problem of high-accuracy dynamic phase measurement and has excellent generalization ability.


Spinal cord injury (SCI) is the injury of the spinal cord from the foramen magnum to the cauda equina which occurs as a result of compulsion, incision or contusion. Spinal cord injury patients lead to loss of functional outcome like balance, strength and general mobility because of which may lead to life threatening condition that carries a high risk of morbidity and mortality. Spinal cord injury patients (SCI) should undergo balance rehabilitation to restore the key determinants of ambulation, such as balance, strength, muscle tone, and proprioception. Recently, studies have used virtual reality (VR) as a promising tool for clinical rehabilitation in a variety of neurological disorders.
Purpose: To evaluate the effect of virtual Rehabilitation on Functional Outcome for Wheel chair Navigation In patients with Spinal Cord Injury
Methodology: Eight SCI patients with Cervical and Thoracic level Injury were included in this study. Patients were divided into two groups: Conventional Group (04patients) and Experimental +conventional Group (04 patients). Both groups underwent the conventional rehabilitation program. An additional training with VR therapy was conducted for 6 weeks with 20 minutes per session and 3 sessions per week. The outcome measures were Modified Functional Reach Test, Range of Motion of Upper Limb and Wheelchair Propulsion Test.
Result: In this study Virtual Rehabilitation Group showed significant improvement in Balance, ROM and Wheelchair Propulsion compared to Conventional group (p <0.01 considered significant).
Conclusion: Virtual Rehabilitation can be considered as adjunctive therapy for improving functional outcome for wheelchair navigation purpose.

Keywords: Spinal Cord Injury, Virtual Rehabilitation, wheelchair navigation


Regulatory T (Treg) cells induce an immunosuppressive microenvironment that is a major obstacle to successful tumor immunotherapy. Dissecting the regulations between energy metabolism and functionality in human Treg cells will provide insights for developing novel immunotherapies against cancer. We discovered that human naturally occurring Treg (nTreg) and tumor-associated Treg cells exhibit distinct metabolic profiles with predominant dependence on glucose metabolism compared with effector T cells. Activated nTreg and tumor-associated Treg cells depend on accelerated glucose consumption for their cellular senescence induction and suppressive activity in responder T cells during their cross-talk. We further identified that TLR8 signaling selectively inhibits glucose uptake and suppresses metabolic processes of glycolysis in human Treg cells, resulting in reversal of Treg suppressive function and cellular senescence induction. In addition, TLR8 signaling activation downregulates mTORC1-HIF1α signaling in Treg cells that control molecular processes of Treg glucose metabolism and suppressive functions. Our in vivo studies further demonstrated that TLR8 signaling-mediated reprogramming of glucose metabolism and function in human Treg cells can enhance anti-tumor immunity and immunotherapy efficacy in a melanoma adoptive transfer T cell therapy model. These studies identify novel mechanistic links between innate signaling and metabolic regulation of human Treg suppression, and provide a new strategy and concept for tumor immunotherapy.


Fracture of coating materials often occurs at or near the interface, while the mechanism and criterion of interface fracture are not clear yet. A molecular dynamics simulation method was introduced to simulate the interface crack initiation, and the relationship between the interface stress and the interface fracture was found. Although a simplified model was applied, the results still showed some intrinsic features that are useful to study the process of interface fracture. At last, an interface fracture criterion was proposed.


In this study, the effects of varying molding conditions, including melt temperature, mold temperature, and injection speed, on the mechanical properties of injection molded nylon-6/fluoromica nanocomposite (Unitika) were investigated. A DSC test and SEM were used to examine the microstructure of material and verify the experimental results. Results showed that the addition of 5 wt% nano-fluoromica particles to pure nylon-6 increases the tensile strength over 20% and the flexural strength more than 38%, but decreases impact strength by less than 2%. Results also indicate that the tensile strength and flexural strength of the nylon-6/fluoromica nanocomposite increase with increased melt temperature, mold temperature, and injection speed. However, the impact strength of nylon-6/fluoromica nanocomposite increased with increased melt temperature, but decreased with increasing mold temperature and injection speed. The DSC measurement revealed that the crystallinity of nylon-6/fluoromica nanocomposite increases with all molding parameters. The SEM results also indicate that the nylon-6/fluoromica nanocomposite is more brittle than the pure nylon-6.

ABSTRACT This article proposes a number of frequency domain estimation procedures for the ARFIMA model based on a spectral generalized method of moments (SGMM) estimator. It is shown that the SGMM estimator includes as special cases; the GPH regression estimator, a spectral instrumental variable estimator, and a spectral nonlinear least squares estimator. A discussion of the large sample properties for the SGMM estimator for both general and specific ARFIMA models is presented. A Monte Carlo experiment shows that the small sample properties of the SGMM type estimators are quite promising when compared to time and frequency domain maximum likelihood.


The paper proposes provisioning methods for VoD service providers offering adaptive video streaming in a cloud environment. Our methods minimize costs paid by VoD provider thanks to rational use of on the fly video transcoding service which eliminates storage cost of rarely requested video profiles. In the paper, we formulate provisioning problem, propose optimization and heuristic methods that determine the best tradeoff between content storage and transcoding. The results of performance evaluation confirmed that proposed methods can significantly reduce costs paid by VoD providers.

Background: The problem of the influence of magnetic fields (FMs) on the growth and development of common bean plants is still far from being fully explained due to its complicated physical nature and the geometry of the seeds. FMs can practically penetrate through living organisms. Aim: The present work aimed to determine the effect of the presowing FM stimulation of common bean seeds on plant growth and development elements. Material and Methods: The present study was based on a field experiment carried out between the years 2015 and 2017 in Żyznów (N 49°81′, E 21°84′, 239 m above sea level). The experiment was carried out using three repetitions of the randomized block method. The experimental factor was the amount of exposure to FM seed stimulation: (I) 15 s, (II) 30 seconds, and (III) the control object without seed stimulation. The plant material of the study was a common bean: cv. Gold Saxa. Results: The biostimulation of the sources with an FM improved the germination energy, strength, and capacity of the seeds. The presowing FM stimulation of the common bean seeds favourably affected the fresh weight of the first and fifth leaves but did not affect their dry weight. The leaves' collection dates measured the new first and fifth plates and their dry weight content. The collection dates of the leaves determined the level of the fresh weight of the first and fifth leaves and the content of their dry weight. Conclusions: The biostimulation of the seeds with the FM contributed to a higher germination capacity, energy, and strength of the common bean seeds. The highest level of the leaves' fresh weight was achieved during full flowering, and the highest dry matter content of the leaves was found in the phase of pod setting.


Understanding the impact of extractant functionalization in solvent extraction is essential to guide the development of better separations processes. Traditionally, computational extractant design uses electronic structure calculations to determine the metal binding energy of the lowest energy state. Although highly accurate, this approach does not account for all the relevant physics encountered under experimental conditions, such as temperature effects and ligand flexibility, in addition to approximating solvent-extractant interactions with implicit solvent models. In this study, we use classical MD simulations with an advanced sampling method, metadynamics, to map out extractant molecule conformational free energies in the condensed phase. We generate the complete conformational landscape in solution for a family of bidentate malonamide-based extractants with different functionalizations of the head group and the side chains. In particular, we show how such alkyl functionalization reshapes the free energy landscape, affecting the free energy penalty of organizing the extractant into the cis-like metal binding conformation from the trans-like conformation of the free extractant in solution. Specifically, functionalizing alkyl tails to the center of the head group has a greater influence on increasing molecular rigidity and disfavoring the binding conformation than functionalizing side chains. These findings are consistent with trends in metal binding energetics based on experimentally reported distribution ratios. This study demonstrates the feasibility of using molecular dynamics simulations with advance sampling techniques to investigate extractant conformational energetics in solution, which, more broadly, will enable extractant design that accounts for entropic effects and explicit solvation.


The Mustang Flat oil and gas field in T36S, R23E, Utah, was discovered by Texas Eastern Skyline Oil through the integration of regional geologic concepts and seismic stratigraphic techniques. Mustang Flat currently is capable of production from five wells in the Ismay (Des Moines) Member of the Hermosa Formation. The reservoir is developed from limestones and dolomites associated with the deposition of algal (Ivanovia) mounds. The porous section ranges from 30 to 104 ft (9 to 32 m) thick, using a 7% porosity cutoff (as indicated on a compensated neutron log). A hydrocarbon column of at least 180 ft (55 m) has been established; a water contact has not been encountered. Developmental drilling is continuing. Two wells are capable of production from the Desert Creek. The Patterson field in T37S, R24E, served as a model for exploration. Regional seismic and subsurface studies revealed the Patterson field to be associated with a break in the slope of a postulated paleoshelf. In addition, modeling indicated that porosity within the Ismay could be recognized from seismic data. From regional seismic control, the paleoshelf break was traced to the northwest into T36S, R23E. Seismic data revealed a broad northeast-southwest-trending nose that intersected the paleoshelf break, and porosity indicators were noted. Seismic and leasing programs were subsequently begun. Portable shothole seismic equipment was used because of terrain considerations. High-resolution acquisition and processing techniques were utilized. Careful analysis of isochron and time struct re maps, and use of porosity indicators resulted in the Mustang 1 discovery location. Subsequent drilling and seismic work have revealed pitfalls of which the seismic interpreter should be aware. End_of_Article - Last_Page 844------------

The measured result shows that, at 6GHz center frequency, the impedance bandwidth is 22%(VSWR < 2), 3 dB gain bandwidth is 28%, the maximum gain is 14.77 dBi, and output power at Pl dB point is 23 dBm.


Trophoblasts are gatekeepers at maternal-fetal mucosal interface, but trophoblast-derived molecules that initiate and maintain maternal-fetal mucosal immunity are not fully understood. We found that HEXIM1, an inhibitor of P-TEFb essential for eukaryotic RNA Pol II-mediated transcription, is highly expressed in human villous and extravillous trophoblasts. Hexim1-/- mouse placentas exhibit abnormal placental immunity characterized by increased maternal leukocyte and T cell infiltration, a paucity of spiral arteries and reduced placental size. HEXIM1 interacts in trophoblasts with AIRE, a protein critical for central and peripheral immune tolerance, via 7SK snRNA. Such interaction is further dependent on the nuclear localization domains of HEXIM1 and AIRE. Extravillous trophoblasts in human preterm labor with placental inflammation have reduced HEXIM1 and increased AIRE expression. Silencing HEXIM1 in trophoblasts led to increased Treg induction by trophoblasts. Our findings identify trophoblasts as a new type of extrathymic AIRE-expressing immunoregulatory cell, reveal a novel function of epithelial cells in mucosal immune regulation via AIRE-mediated Treg induction, suggest HEXIM1 and AIRE establish a transcriptional counterbalance in trophoblasts to maintain maternal-fetal mucosal immunity in pregnancy by regulating P-TEFb and Pol II, and promote a better understanding of how certain pathogens, such as HIV-1, perturb mucosal homeostasis after hijacking the HEXIM1 machinery.


The model of nonlinear and unstable oil film force was combined with Muszynska mode of seal fluid and the concerned nonlinear dynamics was studied. Complex dynamical responses of airflow-induction are detected with rotary speed variation, which include periodic and quasi-periodic vibrant phenomena with strong nonlinear character.


Database management systems evolved in response to the need for efficient maintenance of increasingly large amounts of data. The relatively slow speed of secondary storage devices holding the data is one of the main limitations of database design. Hence, the internal organization of databases has been the primary focus of research in the past. Another major influence on database research was the need to share information among a variety of users. In such an environment, strict rules governing the manipulation of data had to be imposed to preserve the integrity of the database and to guarantee privacy for each user. These needs led to the development of several basic data models. With the steadily increasing demand for user-oriented systems, however, new trends in database technology have evolved outside of the scope of the traditional data models. In this article the authors are concerned with two closely related efforts: (1) The incorporation of more semantic modeling capabilities into database models. (2) The development of better user environments, which include user-friendly interfaces and support different user views of the content and organization of the data.


This paper uses monthly firm-level data to characterize fuel choice and technical change in the US electricity generating industry under the tradable sulphur allowance program. We use data covering the years 1990–2004 in a flexible translog cost function model to determine demand and substitution elasticities for the three main fossil fuel inputs (coal, oil, and natural gas) and the rate and direction of technical change. Capital is assumed fixed, implying a short run analysis. Three variable cost models are presented: one including three fuel inputs which incorporates the sulphur allowance price into the fuels' relative input prices, one with four inputs (three fossil fuels plus sulphur permits) which assumes firms treat allowances as a separate input of their own right, and a third that excludes allowance prices from the cost model. Model 1 is shown to fit the data slightly better, and firm heterogeneity is shown to be present. The interfuel substitution elasticities and technical change estimates presented are therefore based on the fixed effects seemingly unrelated regression (SUR) estimation of Model 1's restricted variable cost function and associated fuel cost share equations.


Early childhood education in the golden age is very important because at this time children's intelligence is growing rapidly. The stimulation given is not only for cognitive intelligence but also for social emotional, character, and noble character needs to be stimulated. The role of teachers and parents in facilitating children when providing learning stimuli through their experiences needs to be designed and arranged in such a way that all aspects of children's development can develop optimally, therefore there is a need for educational game tools as learning facilities for early childhood. APE innovation socialization was carried out to RA teachers in Plered and Tegalwaru sub-districts in two stages, namely presentation and training, the first stage was in the form of exposure to the importance of APE in the learning process in early childhood, the second stage was training involving participants in carrying out APE innovation-making activities in developing all aspects early childhood development. Based on the results of the analysis of the interview and observation data, it was revealed that the creativity of teachers in making APE innovations could increase not only by providing material but also participants being directly involved in the manufacturing process and sharing innovations with colleagues so that innovation could develop.


N ANALYSIS has been made of data on A 727 patients who appeared at hospitals and tumor clinics in search of diagnosis for a symptom that could be caused by cancer. The data were collected and analyzed during the period 1951 to 1954 by the Cornell University Department of Sociology and Anthro-pology, and the study was sponsored by the Bureau of Cancer Control of the New York State Department of Health. This project attempted to answer the question: what is the relative importance of certain factors in accounting for the observed tendency of some patients to delay seeking diagnosis for possible cancer symptoms?


Radiation therapy aims to deliver the prescribed amount of dose to a tumour at the same time as sparing the surrounding tissues as much as possible. In charged particle therapy, delivering the prescribed dose is equivalent to delivering the prescribed number of ions of a given energy at each position of the irradiation field. The accurate delivery is committed to a dose delivery (DD) system that shapes, guides and controls the beam before the patient entrance. Most of the early DD systems provided uniform lateral dose profiles by using different devices, mainly patient-specific, placed in the beam line to shape the three-dimensional final target dose. More recently, systems that provide highly conformal dose distributions using thousands of narrow beams at well-defined energy were developed which feature advanced scanning magnets and real-time beam monitors, without patient-specific hardware. This lecture will cover the general dose delivery concept as well as the different DD instrumentations depending mainly on the beam delivery technique and on the particle and accelerator types. Some characteristic worldwide DD and beam monitor systems will be mentioned.


Synopsis of Prescriptions of the Golden Chamber provides the therapeutic methods for dampness, fluid retention and edema: diaphoresis for dampness, regulation with drugs warm in nature for fluid retention and diaphoresis and diuresis for edema. The author believes that the three methods are established based on the pathogenic factors and are mutually related at the same time.


The present study aimed to detect the distribution range and layer of apocrine sweat gland in Han patients with axillary osmidrosis and to select proper therapeutic regimen. Skin and subcutaneous tissue in axillary region were examined by H&E staining. The location of apocrine sweat gland in skin and tissue of axillary region and its correlation with other skin and tissue were observed under microscope. Axillary osmidrosis was treated by tumescent anesthesia, negative pressure aspiration and scissors pruning. The distribution range and depth of apocrine sweat gland in patients with axillary osmidrosis were basically identical with those of hair follicles of hirci, and they are mainly distributed in the reticular layer of corium and superficial adipose layer. The wounds of 56 patients healed well in our group, without recurrence. Tumescent anesthesia, negative pressure aspiration and scissors pruning could be adopted in the treatment of axillary osmidrosis, and good therapeutic effects were obtained.

Abstract The temperature dependence of the A1 modes at the tetragonal-cubic phase transition in BaTiO3 has been studied by Raman measurements in the forward scattering geometry. The unshifted broad structure at around 270 cm−1 in polariton spectra as well as its presence in the cubic phase is explained. The "disorder" model of Comes, Lambert and Guinier is used to explain the phonon behavior at the phase transition. A comparative analysis with recent infrared studies and previous Raman works is also made.


Information on the occurrence and distribution of plagues of house mice, Mus domesticus, in South Australia was obtained from scientific literature, agricultural reports, rural and suburban newspapers, and personal observations. In all, 580 separate reports from the cereal-growing areas of South Australia in 20 years between 1900 and 1984 were collated to determine the extent of each plague. Some plagues were widespread, affecting nearly all 22 000 km2 of the cereal-growing areas; others were restricted to specific areas or isolated sites. Maps showing the extent and relative severity of mouse infestations are presented for 20 years between 1904 and 1984.


In order to extend the scope and improve the efficiency of supercritical CO2 extraction,four enhanced technologies including supercritical CO2 extraction with modifier(SCE),supercritical CO2 extraction with ultrasound combined modifier(USCE),supercritical CO2 reverse microemulsion extraction(SCRME) and supercritical CO2 reverse microemulsion extraction with ultrasound(USCRME) were applied to extract ginsenosides from ginseng.Their extracting kinetic models were built based on transfer theory and principle of mass balance.The results showed that the extraction yields of ginsensides by SCE,USCE,SCRME and USCRME were 0.26%,0.45%,0.76% and 1.15%,respectively.The extraction rates of ginsensides by four methods showed similar order to the extraction yield.The fitting degree of the model and the experimental data was more than 99.5%.The maximum E∞(1.213%) and k(0.659) values were obtained by USCRME model simulation,which were 3.95 and 1.32 times,respectively,of those by SCE.The results demonstrated that supercritical CO2 extraction enhanced by ultransound combined with reverse microemulsion could improve the extraction yield and rate of polar material ginsensides.


Malignant peripheral nerve sheath tumour (MPNST) is a rare occurrence in the mediastinum. It is biologically aggressive and is generally resistant to chemoradiation therapy. The mainstay of treatment is complete surgical resection. We report a large MPNST which invaded into the adjacent aortic wall in a 50-year-old man. Extensive resection, which included aortic reconstruction under cardiopulmonary bypass and deep hypothermic arrest, was necessary for a good long-term outcome.


The SPICE system of navigation and ancillary data possesses a number of traits that make its use in modern space missions of all types highly cost efficient. The core of the system is a software library providing API interfaces for storing and retrieving such data as trajectories, orientations, time conversions, and instrument geometry parameters. Applications used at any stage of a mission life cycle can call SPICE APIs to access this data and compute geometric quantities required for observation planning, engineering assessment and science data analysis. SPICE is implemented in three different languages, supported on 20+ computer environments, and distributed with complete source code and documentation. It includes capabilities that are extensively tested by everyday use in many active projects and are applicable to all types of space missions - flyby, orbiters, observatories, landers and rovers. While a customer's initial SPICE adaptation for the first mission or experiment requires a modest effort, this initial effort pays off because adaptation for subsequent missions/experiments is just a small fraction of the initial investment, with the majority of tools based on SPICE requiring no or very minor changes.


Advances in science and technology or digital developments are increasingly advanced today, making it easierfor people to get what they want without moving much, this condition is often encountered today. That way aperson's tendency to experience osteoarthritis due to an unhealthy lifestyle is often found. These factors willresult in the development of diseases experienced by the public due to biological, physical, chemical anddegenerative processes. In the case of osteoarthritis is often also referred to as a degenerative disease.Physiotherapy in this case will look at the effect of giving micro wave diathermy in cases of genu osteoarthritisin reducing pain. This research design is a randomized pre and post test group design. The sample in thisstudy was 10 people who experienced genu osteoarthritis and felt pain. The age of the sample in this studywas 40-60 years. The test used to collect pain data in this study was the visual analog scale / VAS. Where thesample is measured its VAS value before (0-session) and after treatment (6 sessions) on each subject. Theresults of the average VAS in the sample experienced a decrease in pain.


Introduction Echocardiography is a standard tool for evaluating the cardiac chambers, valves and great vessels. Recent data shows techniques such as strain analysis display subtle contractile deficits long before ejection fraction (EF) drops, and this has already been linked to poor outcome. 4D colour doppler is a recent technical advancement, however its temporal resolution remains limited so far. Cardiovascular magnetic resonance (CMR) offers similar assessment of myocardial function, vessels and valves, but beyond that also offers unmatched tissue characterization (fibrosis, scar, edema, oxygenation, metabolics). A novel development in this field is 4D flow CMR, which allows for visualization and quantification of multiple parameters like blood flow velocity, direction, pattern, wall shear stress and kinetic energy deposition. Cardiac diseases in early stages may not yet feature a reduced EF but may already display abnormal 4D flow patterns, which may reduce cardiac index and increase ventricular wall stress. In this study we applied CMR-based 4D intraventricular blood flow assessment in participants with normal left ventricular (LV) systolic function. Methods Using a 3T clinical MRI, seven participants underwent a non-contrast exam (one healthy control under 35 years, five controls older than 50 years, one patient with heart failure and preserved EF (HFpEF)). A 4D block of the thoracic cavity was acquired and blood flow patterns in the left ventricle were assessed for direct flow (blood that enters and leaves the ventricle during one heartbeat), residual volume (blood that remains in the LV cavity for at least 2 heartbeats), along with delayed ejection and retained flow (figure). Furthermore, ventricular function and strain by feature tracking were measured. Results While participants had an LVEF of 65±3% and a cardiac index of greater than 3.1±0.4 L/min/m2, there was marked variation in intraventricular 4D blood flow patterns (figure). The patient with heart failure had the largest residual volume and lowest direct flow, whereas the young healthy control had the highest direct flow and lowest residual volume. Residual volume in the older controls ranged in between these two points. Furthermore, a larger direct flow was correlated with greater longitudinal strain (r = -0.886, p = 0.033), while there was a trend of larger residual volume to be associated with poorer global longitudinal strain (r = 0.829, p = 0.058). Discussion In a small cohort, CMR-derived patterns of intraventricular 4D blood flow and ventricular wall strain are associated despite quantitatively normal LVEF. Although acquisition, processing and quantification in 4D flow CMR are still time-consuming, the quantification of 4D blood flow in cardiac chambers and great vessels has the potential to offer a comprehensive evaluation of cardiovascular haemodynamics under normal and pathological conditions. Larger studies are required.


The announcement of the Revelation on the Priesthood of 1978, which extended the priesthood to all worthy Latter-day Saint men regardless of race, was celebrated as the arrival of a "longpromised day" (Doctrine and Covenants, Official Declaration-2). As I reflect on the upcoming thirtieth anniversary of that revelation, I feel deep gratitude to the Lord for sending me to earth in an age in which I would be allowed to hold the priesthood and work in his vineyard. The blessings and privileges my family and I have enjoyed in the Church in these last three decades have far exceeded any dreams we might have had prior to June of 1978.


Purpose Unrecognized clinical deterioration outside the ICU is a serious patient safety concern, with only 43% of pediatric patients surviving to discharge following an in-hospital cardiac arrest Girotra et al., 2013). Past efforts to reduce the impact of deterioration events among non-ICU patients have focused on earlier detection of deterioration via early warning systems (EWS) and faster response times for imminent events. While rapid response teams have improved inpatient mortality rates, existing EWS in this domain have been underwhelming. Further, a chasm remains between development and evaluation of machine learning algorithms in silico (on computers) and the application of these algorithms in clinical settings. To improve …


For the grand challenge of reducing our energy and carbon footprint, the development of renewable energy and energy efficient technologies offer a potential solution. Energy technologies can reduce our dependence on foreign oil as well as the energy consumed by the petroleum industry, the leading consumer of energy by a U.S. industry sector. Nonetheless, the manufacturing processes utilized to manufacture equipment for alternative energy technologies often involve energy-intensive processes. This undermines some of the advantages to moving to 'green' technologies in the first place. Our answer to the Industrial Technology Program's (ITP) Grand Challenge FOA was to develop a transformational low cost manufacturing process for plastic-based photovoltaics that will lower by over 50% both energy consumption and greenhouse emissions and offer a return-of-investment of over 20%. We demonstrated a Luminescent Solar Concentrator fabricated on a plastic acrylic substrate (i.e. no glass) that increases the power output of the PV cell by 2.2x with a 2% power efficiency as well as an LSC with a 7% power efficiency that increased the power output from the PV cells by 35%. S large area 20-inch x 60-inch building-integrated photovoltaic window was fabricated using contract manufacturing with a 4% power efficiency which improved themore » power output of the PV cell by over 50%. In addition, accelerated lifetimes of the luminescent material demonstrate lifetimes of 20-years.« less


Studies of the lowermost Old Red Sandstone of South Wales (Pridolian–Lochkovian) have revealed that the mudstones that constitute up to 80% of some of the formations have been deposited in a variety of environments. In addition there is a variety of lithofacies associations present in some mud‐dominated units that suggests diverse mechanisms of deposition. This paper considers the Moor Cliffs Formation and examines four distinct mudrock facies.


A modular three-phase voltage regulator with a fictitious dc-link is proposed. The proposed scheme is the combination of three single-phase modules while each one of the single-phase module is a three-leg ac voltage regulator. Therefore, the proposed voltage regulator reduces the number of main switches and compensates the voltage of each phase independently. Furthermore, a small film ac capacitor is used to replace the electrolytic capacitor, which not only reduce the size of the dc link capacitor and the stress of the switches but also increase the lifetime of the voltage regulator. The proposed scheme can compensate the voltage disturbance such as under-voltage, over-voltage, voltage sag, voltage swell, three-phase voltage unbalance and three-phase load unbalance effectively. Besides, there are several advantages of this structure, for instance: simple system-configuration, rapid voltage-compensation, easy setup-maintenance and decreasing the production cost while increasing the system power density. Eventually, some experimental results are provided to illustrate the steady-state characteristics and transient responses of the proposed modular three-phase voltage regulator.


Background: Chronic infection with the hepatitis C virus (HCV) is a leading cause of liver-related mortality. Direct-acting antivirals (DAAs) have revolutionized treatment by offering profound improvements in sustained viral clearance (SVR) and tolerability resulting in a rapid expansion of treatment for individuals for whom HCV treatment had previously been less feasible, such as those with advanced liver disease or with drug and/or alcohol-related substance use. Given these clinical policy shifts, the primary objective of this study was to assess the impact of SVR on liver-related death among important clinical groups and the secondary objective was to explore changes in predictors of liver-related death by treatment era using real-world data from a large population-based cohort. Methods: We conducted a population-based, linked cohort study of all Ontario residents with HCV viremia between January 1st, 1999, and December 31st, 2018, with follow-up to 31st May 2021 (N=73,411). Population-level health administrative, clinical, and demographic data were accessed at ICES. Cause-specific hazard models were used to explore the impact of SVR on liver-related death and to identify factors associated with the rate of liver-related death in the DAA and pre-DAA treatment eras. The moderating effects of liver disease severity and substance-use disorder on the relationship between SVR and liver-related-mortality was explored by stratification. Results: Among Ontario residents diagnosed with living with HCV, the achievement of SVR was associated with a significant reduction in liver-related mortality (adjusted hazard ratio [aHR] 0.22, 95%CI: 0.20-0.24 vs. no SVR). This was also observed across progressive liver disease severity levels (aHR 0.13, 95%CI: 0.10-0.17 for individuals without cirrhosis; aHR 0.11, 95%CI: 0.06-0.17 for those with compensated cirrhosis, and aHR 0.24, 95%CI: 0.22-0.27 for those with advanced liver disease vs. no SVR) and by substance use status (aHR 0.24, 95%CI: 0.21-0.27 for those with a history of substance use disorder; and aHR 0.21, 95%CI: 0.18-0.24 for those without vs. no SVR). Additionally, factors such as age at diagnosis, sex, liver disease severity, immigration status, birth year, substance use, HBV-coinfection, viral genotype, and markers of social marginalization were independent predictors of liver-related mortality. However, sex and viral genotype no longer displayed significant associations with liver-related death in the DAA era as was observed in the earlier treatment era. Conclusions: This study provides real-world evidence showing the profound impact of SVR on liver-related mortality in a population-based sample of individuals with CHC and highlights the importance of early diagnosis and treatment. This study further demonstrates significant mortality benefits of SVR regardless of substance use status highlighting the importance of supporting marginalized individuals in treatment access.


The invention discloses a method for detecting a polarized SAR target in a feature domain. The objective of the invention is mainly to solve the problem of poor detection effect under a low signal noise ratio condition of an existing detection method. The method comprises the following steps that: feature extraction: polarization features of clutter training samples and test data are extracted, and scale normalization and centralization are performed on the features; training: principal component analysis is performed on training samples in the feature domain so as to obtain a trained projection matrix; and testing: the projection matrix obtained through training is utilized to reconstruct the test data in the feature domain, and detection quantity can be obtained according to reconstruction errors, and detection on the target can be realized through the judgment on the detection quantity. As proved by simulation results, the method of the invention improves detection performance of the polarized SAR target under the low signal noise ratio condition compared with the prior art.


AbstractQuenching of steel components results in complex and hard-to-predict dimensional and shape changes (distortion). Even the components manufactured from different parts of the same semifinished product may show significantly different distortion behaviours during quenching. The reason is thought to be non-uniform distribution of distortion potential carriers in the final component (i.e. alloying elements, segregations, residual stresses and phases) which are accumulated throughout the whole manufacturing chain. This study focuses on the effects of alloying element distribution and segregation on quench distortion. For this aim, long cylinders of various diameters were machined from 45 mm diameter SAE 52100 steel bars, and marked to define their exact positions in the initial bar. Then the cylinders were austenitised in a vertical furnace under nitrogen atmosphere and quenched in a gas nozzle field. The coordinate measurement results show that dimensional changes deviate significantly with machining ...


Inflammatory conditions are associated with tumor development. IL-1 (cid:1) is a multifunctional and proinflammatory cytokine that affects nearly all types of cells. To investigate the role of IL-1 (cid:1) in tumor growth in vivo, we transduced the retroviral vector coding human IL-1 (cid:1) gene into mouse Lewis lung carcinoma (LLC) cells and subsequently inoculated the transformant (LLC/IL-1 (cid:1) ) to syngeneic C57BL/6 mice. Tumors derived from LLC/IL-1 (cid:1) grew faster (240%, day 18, vs null-vector control LLC/neo; p < 0.01) and showed more abundant vasculature (250%, vs LLC/neo; p < 0.05), whereas LLC/IL-1 (cid:1) cells, LLC/neo cells, and wild-type LLC cells did not show any significant difference in the growth rate in vitro. As compared with LLC/neo cells, LLC/IL-1 (cid:1) cells secreted 2-fold the amount of vascular endothelial growth factor and > 10-fold the amount of macrophage-inflammatory protein-2 (CXCL2), one of whose main functions is angiogenesis. Although LLC/IL-1 (cid:1) itself did not secrete hepatocyte growth factor (HGF), the tumor derived from LLC/IL-1 (cid:1) cells also contained a > 4-fold higher concentration of HGF, another angiogenic factor. In situ hybridization of HGF mRNA in LLC/IL-1 (cid:1) tumor sections demonstrated that stromal fibroblasts and infiltrating cells overexpressed HGF mRNA. Moreover, when cultured in the presence of HGF in vitro, LLC/IL-1 (cid:1) cells secreted even larger amounts of vascular endothelial growth factor and macrophage-inflammatory protein-2. The antiangiogenic agent TNP-470 and anti-CXCR2 Ab inhibited the tumor growth of LLC/IL-1 (cid:1) cells in vivo. These results indicated that secreting IL-1 (cid:1) into the tumor milieu induces several angiogenic factors from tumor and stromal cells and thus promotes tumor growth through hyperneovascularization.

Fresh local strawberries are always a favorite at farmers' markets and roadside stands. Strawberries grow best at temperatures around 70 to 75 F. Utah's cold winters and hot summers provide only a short strawberry season. Greenhouses are designed to maintain optimal growing temperatures, and can be used to grow strawberries year round. However, greenhouses are expensive to both build and operate. High tunnels are relatively inexpensive to build, with some designs costing less than $0.50 per square foot (Black et al., 2008a). Since high tunnels are passively heated and cooled, operating costs are minimal. However, many of the benefits noted for greenhouses, such as early spring and late fall harvests, and better summer production, are realized. High tunnels have effectively extended the strawberry growing season in Utah's Cache Valley from early May to mid December. Plant Selection


Background Previous studies on the counselees' perception of DNA-test results did not clarify whether counselees were asked about their recollections or interpretations, and only focused on patients' own risks and not on the likelihood that cancer is heritable in the family. We tested differences and correlations of four perception aspects: recollections and interpretations of both cancer-risks and heredity-likelihood. In a retrospective study, women tested for BRCA1/2 on average 5 years ago completed questionnaires about their perception. Participants had received an unclassified-variant (n=76), uninformative (n=76) or pathogenic-mutation (n=51) result in BRCA1/2. Analyses included t-tests, correlations and Structural-Equation-Modelling.


Phosphate adsorption-release curves were determined for clay (< 2 μm) and silt (2–20 μm) fractions of surface and subsurface horizons of a Black Chernozem and two Solodized Solonetz soils. The clay fractions from the Chernozem adsorbed about one and one-half times more phosphate than silt at comparable equilibrium concentration and in the case of the Solodized Solonetz soils between two and ten times more was adsorbed. Zeolite (clinoptilolite) in the silt fractions of the two Solodized Solonetz reduced phosphate adsorption markedly and in one case resulted in a negative adsorption. It is believed that either previously adsorbed phosphate or even structural phosphate proxying for silicate in the mineral was released upon dissolution of the zeolites. X-ray diffraction analysis showed that zeolites in one profile dissolved whereas that in another profile was more resistant to dissolution under the same chemical conditions. The phosphate release patterns coincided with the instability of the zeolites in these...


Reliability and accuracy of the vitreous potassium concentration as an indicator of the post-mortem interval (PMI) in cattle were studied. Sampling not more than 1 ml of vitreous humor from the centre of the corpus vitreum was found to improve both accuracy and reliability. A significant correlation between the PMI and the vitreous potassium concentration was found to be present in cattle.

My first reaction on seeing the title was to ask 'does the world really need another textbook on urological laparoscopy?'. While it could be argued that all of laparoscopic urology is relatively new (and therefore contemporary) there are few topics that have not been covered extensively in the literature. Indeed, a great deal has been written on the subject. Nevertheless, I found this book extremely interesting to read, as it covers a wide range of topics that are truly contemporary. The field of urological laparoscopy has been transformed in the past few years as the indications have grown rapidly; this book reflects that rapid growth. The result is fairly uneven, in that some chapters attempt to summarize the literature, while others simply describe new techniques. One senses that the editors did very little editing, making the book more of a collection of articles than a comprehensive definitive textbook. As such, it probably has a very limited lifespan. There may be more of a need for a textbook entirely devoted to laparoscopic techniques which may aid the novice surgeon on the night before his or her first case. I was hoping to find more on several subjects, especially ergonomics and training. Instead, there are 20 pages on the laparoscopic treatment of renal cysts, as well as three separate chapters on hand-assisted laparoscopy. Neither subject, in my opinion, deserves more than a modest chapter. However, I found myself reading each chapter with interest, searching for (and finding) pearls of wisdom from the authors, many of whom can be considered pioneers in the field.

This discussion relates this excellent paper to the Feynman-Kac theorem. On one hand, standard martingale theory makes it possible to derive a partial differential equation for the moment-generating function of the cash flows at one barrier, as in Gerber and Shiu (2003). On the other hand, we consider a specific Wiener functional for which the calculation of the moment-generating function reduces to solving a partial differential equation. The comparison of both differential equations emphasizes the key role of the intriguing boundary conditions (6.1) to (6.4) imposed by Gerber and Shiu in this paper. As in the last remark of Section 5, payments are only made up to time 0. We define D(t) as the aggregate overflow at the upper barrier from time t to , assuming there is no lower barrier ( 1 0). The authors prove in an elegant way that E[D(t)] K( , t, 2) satisfies the partial differential equation (5.15)


Our objective was to determine if treatment with cyclophosphamide (CYC) and mycophenolate mofetil (MMF) improves patient‐reported outcomes (PROs) among patients with systemic sclerosis‐related interstitial lung disease (SSc‐ILD).


Nowadays measurement data coming from all kinds of measurement systems is usually processed by algorithms. These algorithms are often delivered to the user as complex program and their numerical structure is not known. Therefore also influence of algorithm on an accuracy of processed data is not known. Coefficient matrix of algorithm represents its numerical operations and it can be a basis to algorithm accuracy evaluation. The paper presents a method how to identify this coefficient matrix. As an example this method is used to identify an FFT algorithm implemented in LabVIEW.


Inbred strains of mice were found to fall into 3, or perhaps 4, categories with respect to the degree of infection of mature erythrocytes at the end of the first week after inoculation with Plasmodium berghei (Greenberg and Kendrick, 1957): (1) Swiss mice with a mean count of 47% (2) STR mice with a mean parasitemia of about 5% (3) several strains of mice, including C57B1, A, BALB and C3H, with mean counts of about 25% and possibly (4) DBA mice with mean counts of about 35% which may have been a high estimate due to insufficient sampling. F1 hybrids between the extremes (STR and Swiss) had counts averaging about 16%, lower than Swiss but not as low as STR (Greenberg and Kendrick, 1958). The F2 hybrids of this cross also had counts averaging about 16% and there was no good evidence of segregation and recombination of genes effecting parasitemia. It was felt that more information could be obtained by testing the response of hybrids between Swiss and strains of mice which fell into categories 3 and 4 above. It was also thought that further clarification might result from testing hybrids of at least one of the strains of category 3 or 4 with STR, and for this purpose C57B1 was selected. The use of these hybrids may also answer some questions about inheritance of resistance to malaria as reflected in survival. It has been observed (Greenberg, Nadel and Coatney, 1954; Greenberg and Kendrick, 1957) that 4 inbred strains of mice had nearly identical survival patterns: Swiss, C3H, A, and DBA. In all of these strains a large percentage of the mice died after infection with P. berghei in an early wave of death with a mode at about the seventh day. It also has been observed (Greenberg, Nadel and Coatney, 1953; Nadel, Greenberg, Jay and Coatney, 1955) that when mice with radically different survival patterns were crossed, the hybrids very often lived longer than either parent. This increased vigor could be attributed to a recombination of many genes favorable to survival, or heterosis could be taken to mean that the parent strains differed from each other in many genes somehow involved in resistance to malaria. If, then, phenotypically similar mice were hybridized and heterosis were observed in the offspring, it could be assumed that the parent mice were genetically different with respect to resistance to malaria. There was some indication from a small series (Greenberg, Nadel, and Coatney, 1954) that hybrids between DBA and A lived longer than either parent. The experiments to be described were designed to obtain data on the longevity of hybrids of mice, the parents of which were phenotypically similar with respect to survival with malaria.


Due to their higher coercivity(H C )and magnetocrystalline anisotropy(K u ),smaller size distribution and"single-domain"structures,Co-based all oy and Fe-based alloy magnetic nanoparticle thin films and superlattice struct ures have great potential application for extremely high density recording(EHDR )media,so people are eager to seek effective methods to fabricate magnetic nan oparticle thin films and superlattice structures and to take various measures t o improve the thermal stability and other magnetic properties of recording media .Vacuum deposition techniques,solution phase chemical synthesis and ion implan tation techniques etc are investigated.Great progresses have been made during t he latest few years.


The Lorentzian metric structure allows one to implement the relativistic notion of causality in any field theory and to define a notion of time dimension. We propose that at the microscopic level the metric is Riemannian and that the Lorentzian structure, usually thought as fundamental, is in fact an effective property, that emerges in some regions of a 4-dimensional space with a positive definite metric. We argue that a decent classical field theory for scalars, vectors and spinors in flat spacetime can be constructed, and that gravity can be included under the form of a covariant Galileon theory instead of general relativity.


Taking1 the typical university campus dining halls[1] as the evaluation scenario, based on the QOS (Quality Of Service) and the AHP (Analytic Hierarchy Process) model, a comprehensive evaluation model for university campus dining halls is proposed for the two main user groups and their needs in the school teachers and students and logistics supervision departments. On this basis, an evaluation system is designed to provide targeted functions and sufficient data support for evaluation feedback, operational optimization and regulatory decision-making in university campus dining halls.


Objective: To investigate a potential relationship between I/D polymorphism within intron 16 of the angiotensin-converting enzyme (ACE) gene located on human chromosome 17 and Behçet's disease. Materials and Methods: Genomic DNA was obtained from 35 Turkish patients diagnosed with Behçet's disease according to the International Study Group criteria and 150 healthy individuals. Polymerase chain reaction was used to detect the presence of I and D (insertion and deletion) alleles in intron 16 of the ACE gene in these DNA samples. Results: We found differences in ACE I/D polymorphism between Behçet's disease and healthy controls (χ2 = 4.61, d.f. = 1, p = 0.044). In Behçet's disease patients, the D allele frequency was 84.3% and I allele frequency 15.7%. Conclusion: An association between Behçet's disease and ACE polymorphism may provide a useful basis for future molecular studies and therapeutic approaches in this complex disease.


A certain absolute air pressure sensor applied to monitoring the vacuum degree of diesel engine cabin in marine was described.Air pressure can be converted to the displacement,eventually to the output voltages through the air pressure sensor which is composed of metal diaphragm,linear variable differential transformer(LVDT).And the working principle and performance of the metal diaphragm and LVDT were analyzed according to the characteristics of the air pressure sensor.The mathematical models about pressure-displacement-voltages were established,which was based on the research of the ripple configuration of the metal diaphragm and the relationship among displacement,magnetic field,mutual inductance and output voltages.The analysis results show that the performance of pressure-displacement is determined by the modulus of elasticity,ripple configuration,thickness and diameter of the metal diaphragm,and the performance of displacement-voltages is mainly influenced by the excitation voltages and LVDT' s structure parameters such as the length and radius of both coils and core,turns of both primary coil and secondary coils.


Abstract Given that private schools are institutionally divided into the binary structure of for profit and nonprofit, the existing tax laws and policies aimed at private education feature obvious flaws. Reforms to the taxation system for private education should bring it in line with the state's binary structure for the division of private schools, highlighting the charitable nature of private education, and instituting a more refined and scientific taxation system for private education.
