Evidence is found that for zero spin density $m=0$ and the range $0<x<x_c$ of finite hole concentrations of the short-range spin ordered phase where $x_c=1/\pi$ for $U/4t\to\infty$ and $x_c=0.27$ for $U/4t\approx 1.525$ the ground state of the Hubbard model on the square lattice is superconducting. Superconductivity emerges naturally from the effects of the residual interactions of the square-lattice quantum-liquid $c$ and $s1$ fermions and as a side product of the short-range spin correlations. The investigations of this paper rely on a description of that quantum problem in terms of objects which arise from a suitable electron - rotated-electron unitary transformation. Occupancy configurations of such objects generate the energy eigenstates and correspond to the representations of the $[SO(4)\times U(1)]/Z_2$ group which was found recently to refer to the model global symmetry. The studies of this paper focus on the effects of the residual interactions of the $c$ and $s1$ fermions of the square-lattice quantum liquid which emerges from the model in the subspace spanned by the ground state and the excited states generated by application onto it of one- and two-electron operators. An excellent overall agreement is reached for the magnitudes of all energy scales of four representative systems of the hole-doped cuprates: Bi$_{2}$Sr$_2$CaCu$_2$O$_{8+\delta}$, Tl$_2$Ba$_2$CuO$_{6+\delta}$, YBa$_2$Cu$_3$O$_{6+\delta}$, and La$_{2-x}$Sr$_x$CuO$_4$.


The Smith Institute, in association with the Economic Strategy Research Bureau at Nottingham Business School, has undertaken an investigation into the lack of central government investment in the East Midlands in housing and physical regeneration. The work has been based on desk research, two round tables with stakeholders (in Nottingham and Melton Mowbray) and interviews with over 30 decision makers, experts and opinion formers from across the region. The objectives of the report were: first, to quantify the reduction in central government investment in the region compared with other regions; second, to suggest reasons why this might have
occurred; third, to consider the impact that this might be having on the implementation of government policies such as housing provision, "rebalancing" the economy and achieving greater value for money for government investment. The report concludes with a number of recommendations for local enterprise partnerships
(LEPs), local authorities, the housing sector and central
government.


Conrad Black ranks highly among a select group of global media moguls in the world today. This article traces the rise of the Black empire from the 300-circulation Quebec weekly purchased for a dollar in 1966, to his current company, Hollinger Inc, which owns or controls a string of publications across four continents. More importantly, it examines the man behind this empire, looking at Conrad Black's background, education, career and the personal traits that have made him such an imperious figure. It deals with Black's particular proprietary style, which is of particular significance to an Australian audience who are still unfamiliar with this influential shareholder in the Fairfax group, and discusses why Black is very much a product of his homeland.

A Victorian low-rank coal (Loy Yang) was acid-washed and ion-exchanged with Na and Ca to prepare the H-form, Na-form, and Ca-form coal samples. Two more H-form samples were also prepared by rewashing the Na-form and Ca-form samples with acid. These coal samples were pyrolyzed in a wire-mesh reactor where the secondary reactions of the evolved volatiles were minimized. The ion-exchanged coal samples were found to give very different tar yields from those of the raw coal samples. While the tar yields from the pyrolysis of the raw and H-form coal samples were observed to be very sensitive to changes in heating rate, the tar yields from the Ca-form and Na-form samples showed little heating rate sensitivity. Unlike higher rank coals studied previously, the tar yields from the pyrolysis of the raw coal and the H-form coal samples at 600 °C were found to increase much more than the corresponding increases in the total volatile yields as the heating rate was increased from 1 to 2000 K s-1. Reexchanging Na in the ...


PURPOSE
To prospectively evaluate the clinical feasibility of magnetic resonance (MR) imaging of the lungs with fast volumetric interpolated three-dimensional (3D) gradient-recalled-echo (GRE) sequences and to compare this examination with standard computed tomography (CT) in patients with lung abnormalities.

MATERIALS AND METHODS
Twenty-five patients with different lung abnormalities were examined with 3D GRE MR imaging. The small pulmonary nodules in seven, TNM stage of large intrapulmonary tumors in eight, and benign bronchial disease in five patients were evaluated. MR imaging-based diagnoses were compared with diagnoses made at CT and at discharge from the hospital. Contingency tables and the McNemar test were used to evaluate the significance of differences between MR imaging- and CT-based diagnoses.

RESULTS
The MR imaging- and CT-based diagnoses were identical in 24 of 25 patients. In the remaining patient, clinical findings confirmed the accuracy of the MR imaging finding of pleural empyema. Ten of 15 solid pulmonary nodules smaller than 10 mm in diameter were detected at MR imaging (P >.1). Tumor stages at MR imaging and CT were identical, but lymph node stages at the two examinations differed in two of eight patients owing to overestimation of lymph node size at MR imaging (P >.2). In the five patients with bronchiectasis, MR imaging depicted 26 of 33 affected lung segments; differences between MR imaging and CT findings of bronchial dilatation (P >.05) and bronchial wall thickening (P >.2) were not significant. Peribronchial fibrosis was overestimated at MR imaging owing to image artifacts (P <.05).

CONCLUSION
Study results confirmed the feasibility of fast breath-hold 3D GRE MR imaging of the lung.

Abstract Background There have been few studies to date exploring prognostic outcomes associated with idiopathic sudden sensorineural hearing loss (ISSNHL) in order adults. Objective This investigation was designed to explore the relationship between atherosclerosis-related risk factors and ISSNHL outcomes among older individuals. Material and methods In total, 172 older adults diagnosed ISSNHL from 2016 to 2021 were retrospectively evaluated to compare demographic and clinical test results. Results Relative to healthy controls, ISSNHL patients exhibited significant differences in hypertension incidence and factors related to coagulation. With respect to prognosis, age, onset days, hypertension, the degree of hearing loss, type of hearing curve, fibrinogen and D-dimer levels were significant univariate prognostic factors, whereas multivariate logistic analysis showed that hypertension (p = .005) and D-dimer concentration (p = .000) were related to the treatment outcome of older ISSNHL patients. The area under the curve (AUC) for D-dimer levels was 0.795 (95% CI: 0.724–0.866). When using a D-dimer cut-off threshold value of 107.5 ng/mL, the sensitivity and specificity values of 77.0% and 76.7%. Conclusions The present results indicate that hypertension incidence and D-dimer levels may be presented as an important prognostic indicator in older affected ISSNHL individuals.


Background and Objective: Urinary tract infections believe to be one of the main acquainted infections by Escherichia coli in hospitals with an excessive incidence of illness. This study aimed to analyze the antibiotic resistance profile and molecular characteristics of E. coli isolates recovered from patients with urinary tract infection at different hospitals in Taif Governorate, Saudi Arabia. Materials and Methods: Out of 143 isolates collected for 11 months, from February-December 2019, 24 isolates were identified as E. coli by API system and 16S rRNA sequences techniques. An antibiotic sensitivity test was performed using the disk diffusion method. Besides, the repetitive sequence repeat-PCR (Rep-PCR) technique was used for genotyping the 24 isolates. Results: Almost all isolates were resistant to most tested antibiotics such as ampicillin, ceftazidime, cefepime, trimethoprim/sulfamethoxazole, amox/clavulanic. The PCR results show that virulence genes kpsII and yaiO were detected in all E. coli isolates. Stx1, fimH, hly and uidA were moderate detected in all isolates. Conclusion: The high frequencies of antibiotic-resistant E. coli isolates in patients with urinary tract infections in the current study suggest that continuous surveillance of the use of appropriate antibiotics is required and that control of infections is necessary.


Switching operations of circuit breakers and disconnector switch radiate transient electromagnetic fields which may interfere and disrupt normal operations of sensitive electronic equipment in power substations. This paper deals with the calculation of transient electromagnetic fields generated due to the switching operation in power substation by the method of Moment (MoM) and superposition principle. Measurement of the transient electromagnetic fields in some points is carried out for two opening and closing small capacitive current test circuits (one using air insulated switchgear and the other using gas insulated switchgear) by fiber-optical measurement system, and the average error between the calculation and measurement result is about 15%-25%. Analysis of the calculation result shows that the transient electromagnetic field at a point mainly depends on the position and the radiated source characteristics. The calculation result could be applied to the EMC analysis of electronic equipment in power substation.


Acute myeloid leukemia (AML) is a heterogeneous, aggressive hematological malignancy with dismal prognosis where limited targeted therapies are currently available. Poly-(ADP-ribose)-polymerase (PARP) inhibition has emerged as an important therapeutic arsenal to target homologous recombination-deficient tumors. However, molecular understanding of PARP blockade in the context of epigenetic derangements and transcriptional plasticity in human elderly AML pathogenesis remains unexplored. KDM6 proteins are H3K27 demethylases that critically regulate chromatin architecture in multi-cellularity and tumorigenesis (Tran, Mol Cell Biol 2020). KDM6A escapes X-chr inactivation, and Utx-/- female mice spontaneously develop aging associated myeloid leukemia (Gozdecka, Nat Genet 2018; Sera, Blood 2021). In addition, KDM6A loss of function mutation is implicated in AML relapse (Stief, Leukemia 2020). In contrast, KDM6B primarily exerts an oncogenic function in heme-malignancies. Together, KDM6A and KDM6B play cell type-specific function in leukemia, and KDM6 proteins and associated signaling emerge as important focal point for developing molecular targeted therapy.
 We identify that KDM6 demethylase activity critically regulates DNA damage repair (DDR) gene expression program in AML. Transcriptome analysis indicated a significant downregulation of expression of DDR genesets in both KDM6A deficient human AML and Utx -/- pre-leukemic cells. Lentiviral shRNA screening performed in response to low-dose γ-irradiation in AML stem cells, revealed a radioprotective function of KDM6A. Expression of KDM6s is regulated by genotoxic stress in a time-dependent manner, and deficiency of JmjC catalytic function impaired DDR transcriptional activation and compromised repair potential. Mechanistically, quantitative ChIP experiments also revealed co-operation between KDM6A and SWI/SNF facilitating dynamic chromatin remodeling at TSS/promoter to induce DDR gene expression. To interrogate changes in chromatin accessibility we performed ATAC-seq analysis in KDM6 deficient AML. Motif enrichment highlighted that while KDM6A depletion led to reduced chromatin access to 140 transcription factors (TFs), only 56 TF binding sites showed increased accessibility. Overall, changes in chromatin accessibility, associated with a reduced binding of DDR regulatory TFs in KDM6 deficient AML, account for a compromised DDR function.
 In agreement with these findings an array of KDM6 deficient AML cells were more sensitive to PARP inhibition, and pre-clinical mice models xenotransplanted with KDM6A loss of function AML line showed an increased susceptibility to PARP blockade in vivo. FLT3-ITD positive AML with a lower KDM6A expression was more sensitive to olaparib. In addition, olaparib administration significantly reduced bone marrow engraftment of patient-derived xenografts of KDM6A-mutant primary AML. Interestingly, KDM6A expression is upregulated in venetoclax-resistant monocytic-AML compared to venet-sensitive primitive-AML. Using venet responsive isogenic lines we demonstrated that attenuation of KDM6 function increased mitochondrial activity, intracellular ROS levels, de-repressed BCL2 expression, and sensitized AML cells to venetoclax. Additionally, KDM6 loss resulted in transcriptional repression of BCL2A1, commonly associated with venet resistance (Zhang, Nat Cancer 2020). Corroborating these results, dual targeting of PARP with BCL2 was superior to PARP or BCL2 inhibitor monotherapy in inducing primary AML apoptosis, and KDM6A loss further enhanced this synergism.
 In sum, our study illustrates a molecular mechanistic rationale in support for a novel combination targeted therapy for AML, and posit KDM6A as a molecular determinant for therapeutic efficacy. Intriguingly, KDM6A functions as a gatekeeper of BCL2 and BCL2A1 expression. Similar to TET2 although bi-allelic Utx loss causes evolution to myeloid neoplasms, minimal KDM6 activity is important for survival of human AML cells. KDM6s have been implicated in solid tumors, and both PARP and BCL2 inhibitors are being tested in cancer patients, underscoring a wider scope of application. To conclude, KDM6A unfolds to be a central regulator for susceptibility of AML to both PARP and BCL2 inhibition, expanding the possibility to characterize effective combination targeted therapy for AML in clinical settings.

A surge generator has been constructed for evaluation of the electromagnetic compatibility(EMC) of electronic and electrical devices, arresters and their non-linear resistant elements when they are subject to high-energy lightning disturbance.The circuit design of the generator is mainly based on the theoretical estimation with specific circuit,together with the experience of the researchers and the simulation of computer yet.As the most widely used method,the approach of Laplas inverse transformation,has not been particularly and systematically presented.Meanwhile,the selection of equation parameters of the current and voltage wave is not fixed.As a result,the design process seems to be complicated and deficient.In this paper,we have presented a new method of design,which is still based on the Laplas theory.However,with the equation transformation,we unified the parameters of the current and voltage waveform with the circuit parameter.Moreover,methods of exhaustion and interpolation are jointly employed in this paper to build the relationship curve of the waveform and the circuit clearly.The method can be briefly expressed as,through waveform parameters to specify a variable by the curve,through the variable to define the parameters of different circuit elements.By the simulation of the Pspice software and the experiments of several surge circuits,the method is demonstrated to be credible.In conclusion,with this method,the selection of generator parameters turns out to be more reasonable,the design efficiency increases and the accuracy is up to the IEC standard at the same time,which means the method can be applied for the researchers to use and design.


125 It is widely appreciated that steel reinforcement plays a critical role in influencing the structural behaviour of members and correct detailing of reinforcements is imperative if the structures are to fulfill their assigned roles. Most engineers tend to take the properties of reinforcement for granted and more often than not remain blissfully ignorant about the influence of the metallurgical and production characteristics on the mechanical properties of structural steel. Given the liberalised import regime and the large-scale conversion of imported scrap in the form of scrap rails, automobile scrap, defence scrap, scrap from ship breaking, etc of unknown or unsuitable quality, into steel rebars, possibly under less-than controlled conditions, raises apprehensions about the quality and reliability of steel rebars used in the construction industry. To be able to take informed decisions about the quality of steel rebars in a holistic manner, it is imperative that structural engineers are conversant with the steel-making characteristics that have a bearing on the mechanical properties of the rebars. In this write-up the production processes for steel rebars are briefly reviewed, followed by a discussion of commercial aspects in the manufacture of reinforcement steel. The current state-of-the-art relating to TMT bars is also presented. Need for pre-qualification criteria for selection of vendors for supply of rebars is highlighted.


Colon cancer is cancer that is present on the inner side of colon walls or the rectum walls in the large intestine. Most of these types of cancer begin as abnormal growth of tissue called as polyp. Colonography uses low dose radiation Computed tomography (CT) scanning to obtain an interior view of the colon making use of special x-ray machine to view the large intestine for cancer and abnormal growths known as polyps. Radiologists examine these images to find polyp like structure using computer tools. As CT Colonography image contain noise such as lungs, small intestine, instruments during image capturing; segmenting colon from noise is the key task. Polyp occurrence can be detected mainly using shape feature; eliminating shapes similar to polyp is challenging. Hence, to tackle above issues, Image processing techniques are used by applying deep learning algorithm - Convolution Neural Network (CNN) and the results are compared with classical machine learning algorithm. In proposed method, each image is pre-processed to filter air filled dark region that includes colon, lungs etc. Next, each pre-processed CT Image separated into fixed number of blocks. Using pre-trained CNN, each block of ROI is classified as Type 1 (Usually Ascending and descending colon), Type 2 (Usually Traversal and sigmoidal colon) and Type3 (Noise such as lungs, instruments) to segment colon blocks by eliminating noise. Classified Blocks is further diagnosed for polyp like structure using pre-trained CNN by classifying each colon block as normal or abnormal. The experiment is setup with classical machine learning algorithms - Random Forest (RF) and k-nearest neighbor (KNN) by extracting texture feature - Local binary pattern (LBP) and shape feature - Histogram oriented gradient (HOG) for comparison. The experiment results showed the accuracy of proposed method for colon segmentation using CNN (87%) outperforms RF (85%) and KNN (83%). In, addition, the polyp detection accuracy of CNN (88%) is better than Random forest (85%) and KNN (80%). Hence, in the proposed method, there is significant accuracy improvement using deep learning algorithm compared to classical machine learning algorithms. It also provide baseline for automated colon cancer diagnosis using Deep learning algorithms for further research.


In an attempt to investigate the use of bacteria and their metabolites as bioflotation reagents for environmentally friendly mineral processing, laboratory cell flotation tests were carried out using copper sulfide ores bearing a high content of pyrite, which were mixed with a biosurfactant-producing mixotrophic bacterium as bioflotation reagents. The interaction of bacterial cells and their metabolic products with the sulfide ores resulted in the alteration of the surface chemistry of both ores and bacterial cells as evidenced by FTIR and SEM-EDS observations as well as surface tension and contact angle measurements. The change in the surface properties of the sulfide ores in turn enabled the bacterium to function as flotation bioregeants in the flotation of copper sulfide ores as a function of bacterial cell concentration, conditioning time, flotation time and pH. Overall, the bacterium and its metabolites as bioreagents yielded flotation recoveries which might be attributed to the multi-function of the bacterium as depressant, collector and frother. Thus, the bacteria tested in this study could potentially be used as flotation bioreagents, providing an alternative to conventional flotation reagents.


Objective To observe the efficacy of midazolam given as a continuous infusion in the treatment of status epilepticus (SE) in adults. Methods Twenty-three adults with SE received a bolus of midazolam 0.1 mg/kg intravenously,followed by a continuous infusion of 0.1 mg/( kg·h). When the episode of seizures continued, a second bolus of midazolam 0.1 mg/kg was given intravenously, and the dose in continuous infusion was increased by 0.05 mg/( kg·h) until the seizures were brought undercontrol. When the totoal amount of dose reached 0.6 mg/(kg·h)and the episode continued, it was reckoned ineffective andno more dose was given. When the episode disappeared for 24 hours, the dose was decresed by 0.05 ~ 0.1 mg/( kg·h) every 12 hours until it ends. Meanwhile, all patients were given one to three kinds of anti-epileptic and the primary affection and related syndrome was treated accordingly. Results The midazolam worked effectively in 13 patients,and had effect on7 patients;no effect was in 3 patients. The efficacy rate came to 86.96%. Three of he patientsgot a low blood pressure and recoverd after given a small dose of dopamine and relevant fluid infusion ;the respiration rate of two patients slowed and was not given treatment for their oxygen saturation remained above 90%.Conclusion Midazolam is an effective and safe drug to control refractory seizures in adults with SE.

Artifacts rejection is crucial to electroencephalogram (EEG) application. Short-term few-channel EEG (e.g., in real-time detection of stress level and motor imagery) brings new challenges for removing artifacts due to less data. The existing artifact removal methods cannot guarantee both effectiveness and efficiency for removing artifacts from short-term few-channel EEG recordings. Consequently, we propose a fast adaptive sub-bands' blind source separation method to remove artifacts from short-term few-channel EEG recordings effectively and efficiently. First, noise-assisted fast multivariate empirical mode decomposition (NA-FMEMD), as a fast adaptive multidimensional sub-bands' decomposition method, is used to decompose short-term few-channel EEG recordings into multidimensional sub-bands. Then canonical correlation analysis (CCA), as a blind source separation method, is used to estimate artifact-related and EEG-related sources. Finally, EEG-related sources are intelligently selected and reconstructed as clean EEG recordings. The results demonstrate that our method takes at least five times less computing time for 2-s few-channel EEG recordings than state-of-the-art methods with similar effectiveness, using the same computer and software. Therefore, our method enhances the efficiency of removing artifacts from short-term few-channel EEG recordings while ensuring effectiveness, and it is more suitable for real-time processing.

Thermosensitive microgels were prepared by CaCO3 template, which exhibited volume change with temperature. Curcumin were encapsulated into hydroxypropyl-β-cyclodextrin (HP-β-CD) to fabricate inclusion complexes through the kneading way, which were then loaded into these microgels. Drug release profiles obtained were found to have enhanced release for the samples above LCST and governed by a diffusion-controlled mechanism. Complex-loaded microgel presented permeation efficiency in respect to temperature.


Polymeric materials have been utilized in semiconductor industries such as pattern formation materials. One of the drawbacks of such polymers is the lack of etch resistance. Metal infiltration into polymer matrices is an emerging technology that could overcome the issue. The gaseous organo-metal precursors penetrate into polymer matrices where they are oxidized to form stable metal oxides. Thus formed organic-inorganic hybrid material shows superior etch-resistance which enables to form patterns with high aspect ratio [1]. One of the most commonly studied processes is the infiltration of trimethylaluminium (TMA) into polymethylmethacrylate (PMMA). One of the issues of this technology is that increase in volume of the polymer after the infiltration is inevitable, since metal oxides are added to the polymer. For example, we observed over 10 % of volume expansion for the combination of PMMA and TMA [2]. If this technology was dedicated to small feature sizes, it would be preferable to maintain its original shape. Poly(tert-butylmethacrylate) (PtBuMA) has a similar structure to PMMA except that it has a tert-butyl group on its side-chain instead of a methyl group. This polymer is known to decompose above 180 degree Celsius, releasing the butyl group in form of 2-butene. If the out-going of tert-butyl group and the in-coming of TMA occurs simultaneously under ambient temperature, we can expect to see a balance of volumetric shrinkage and expansion. In this paper, a concept using PtBuMA to compensate the volume increase after metal infiltration is described.

The very-high-energy (VHE; E > 100 GeV) gamma-ray experiment, VERITAS, detected exceptionally bright flares from the high-mass X-ray binary LS I +61 ◦ 303 during the period October – December 2014. LS I +61 ◦ 303 is a known VHE gamma-ray source, the flux from which varies strongly with the orbital period of ∼ 26 . 5 days. The maximum VHE flux is found around apastron (orbital phase ∼ 0 . 6) at a level typically corresponding to 10 – 15% of the Crab Nebula flux (>300 GeV). During these most recent observations, relatively short (day scale), bright TeV flares were observed from the source around apastron in two orbital cycles (October and November). Both cases exhibited peak fluxes above 25% of the Crab Nebula flux (>300 GeV), making these the brightest VHE flares ever detected from this source. In the last orbital cycle observed (De-cember), the source had returned to its historical level of activity. The results of these VERITAS observations from 2014 will be presented.


In this paper, we propose a simple one-pot methodology for proceeding from atom transfer reaction-induced conventional free radical polymerization (AT-FRP) to atom transfer self-condensing vinyl polymerization (AT-SCVP) through manipulation of the catalyst phase homogeneity (i.e., CuBr/2,2'-bipyridine (CuBr/Bpy)) in a mixture of styrene (St), 4-vinyl benzyl chloride (VBC), and ethyl 2-bromoisobutyrate. Tests of the solubilities of CuBr/Bpy and CuBr2/Bpy under various conditions revealed that both temperature and solvent polarity were factors affecting the solubility of these copper complexes. Accordingly, we obtained different polymer topologies when performing AT-SCVP in different single solvents. We investigated two different strategies to control the polymer topology in one-pot: varying temperature and varying solvent polarity. In both cases, different fractions of branching revealed the efficacy of varying the polymer topology. To diversify the functionality of the peripheral space, we performed chain extensions of the resulting hyperbranched poly(St-co-VBC) macroinitiator (name as: hbPSt MI) with either St or tBA (tert-butyl acrylate). The resulting hyperbranched core star polymer had high molecular weights (hbPSt-g-PSt: Mn = 25,000, Đ = 1.77; hbPSt-g-PtBA: Mn = 27,000, Đ = 1.98); hydrolysis of the tert-butyl groups of the later provided a hyperbranched core star polymer featuring hydrophilic poly(acrylic acid) segments.

1. We begin wit,h some definitions. A function h(X) is said to be a measuring function j: if it has the following properties :(i) m(X) is defined and is continuous in some range 0 <X < &, and positive in 0 < X < h, ; (ii) h"(X) exists and is less than or equal to 0 in 0 < X ,< h, ; (iii) h(0) = 0.

The ocean is inhomogeneous in hydrographic properties with diverse water masses. Yet, how this inhomogeneity has evolved in a rapidly changing climate has not been investigated. Using multiple observational and reanalysis datasets, we show that the spatial standard deviation (SSD) of the global ocean has increased by 1.4 ± 0.1% in temperature and 1.5 ± 0.1% in salinity since 1960. A newly defined thermohaline inhomogeneity index, a holistic measure of both temperature and salinity changes, has increased by 2.4 ± 0.1%. Climate model simulations suggest that the observed ocean inhomogeneity increase is dominated by anthropogenic forcing and projected to accelerate by 200%–300% during 2015–2100. Geographically, the rapid upper‐ocean warming at mid‐to‐low latitudes dominates the temperature inhomogeneity increase, while the increasing salinity inhomogeneity is mainly due to the amplified salinity contrast between the subtropical and subpolar latitudes.


A wood cantilever loaded at the free end was analyzed using the anisotropic elasticity theory. This report presents a two-dimensional numerical example of a Sitka spruce cantilever in the longitudinal- radial plane. When the grain slope is zero, i.e., the beam axis coincides with the longitudinal axis of wood, the stresses in the beam and the deflection of the beam are the same as those for an isotropic beam; when the grain slope is different from zero, the stresses and the deflection can increase significantly.


The smart age has created new goals, and offers novel approaches for teachers' professional development. The acquisition of technological pedagogical content knowledge (TPACK) has become essential for novice university teachers' professional development. With the aim of developing teachers' TPACK, this study constructed a BOPPPS–TPACK training model by following four key design principles: smart-tool-based, pedagogy-driven, microteaching-integrated, and creatively enhanced. This paper describes a practical study involving 145 teachers that was carried out using questionnaire surveys, interviews, and electronic record analyses. The results showed that the BOPPPS–TPACK training process could achieve the effective coupling of BOPPPS and TPACK and enhance novice university teachers' ability to engage in in-depth learning and TPACK transfer, creating a method and system to guide teachers' professional development. Measures such as optimizing the construction of smart environments for teachers' professional development, enriching pedagogical content of knowledge-based representations, and extending feedback collection to practical settings can help to enhance TPACK development.


The SuperKEKB accelerator tunnel has about 30mm displacement in the vertical direction. From the result of optics correction simulations with the tunnel displacement, it was decided that the beamline components align against the smoothed line of the measured tunnel level in order to save the alignment cost and time. In order to compensate the large tunnel displacement, a pre orbit and optics correction based on the tunnel level measurement is applied at the beginning of the phase-1 commissioning, and the beam circulation is achieved with a small number of magnet adjustments. We report the result of the pre correction.


Background: miRNAs play a crucial role in plant development and growth by inhibiting the function of targeted gene mRNAs at the post transcription level. However, none miRNAs in Pseudostellaria heterophylla has been reported and their function in morphogenesis of organs and continuous cropping obstacles is still unclear. Results: A total of 163 conserved miRNAs (belonging to 66 families) and 303 level miRNAs were identified and some of them showed specifically up or down regulated expression in different tissues. Further, numbers of unigenes involved in Plant-pathogen interaction and MAPK signaling pathway-plant was targeted by miRNAs from P. heterophylla by using GO and KEGG analysis. Significant negative correlation between expression profiles of 30 miRNAs and their targets gene (37 unigenes) were observed. Further, a large number of genes involving with signal transduction of auxin, zeatin, abscisic acid and jasmonic acid were targeted by identified miRNAs in P. heterophylla. A predicated target gene of a conserved and novel miRNA was validated by 5′RLM-RACE, respectively. A large number of mRNA from four kinds of endophytes was targeted by miRNAs of P. heterophylla, and most genes were targeted by miR414. Conclusion: We report a population of P. heterophylla miRNAs from four different vegetative organs by high throughput sequencing, and analyzed combining with the constructed transcriptome. These results may help to explain the function of miRNA in morphogenesis of organs and defense of endophytes in P. heterophylla, and provide theoretical basis for breeding and genetic improvement of P. heterophylla.


ADR, the more common notation for alternative dispute resolution, has come to mean many things. The field for various dispute resolution processes and professionals has expanded since the 1960s.1 The mediation of community, business and other types of disputes, has become more commonplace than other forms of ADR.2 This is most likely because mediation as a process generally typifies the problemsolving model of ADR, which makes it appropriate for a variety of disputes. Basically any dispute that can or should be negotiated and settled among the parties is amenable to mediation One of the reasons for the resurgence of some forms of ADR and the emergence of new ADR methods is that the traditional adversarial approach of the nation's legal system came under fire for not meeting the needs of the people.4 Contemporaneously, the roles of the traditional


We investigated whether a functional insertion/deletion (I/D) polymorphism of angiotensin-converting enzyme (ACE) influenced antipsychotic treatment. At baseline, and after 8 weeks of treatment with various antipsychotic medications, we assessed patients' Positive and Negative Syndrome Scale (PANSS) scores, PANSS factors, and metabolic-syndrome-related parameters (fasting plasma lipid and glucose levels, and body mass index). A total of 186 antipsychotic-naïve first-episode psychosis patients or nonadherent chronic psychosis individuals (99 males and 87 females) were genotyped by polymerase chain reaction analysis. The ACE-I/D polymorphism was significantly associated with changes in PANSS psychopathology only (p < 0.05). Compared to ACE-II homozygous males, ACE-DD homozygous and ACE-ID heterozygous males manifested significantly greater decreases in PANSS positive score, PANSS excitement factor, and PANSS cognitive factor. ACE-DD homozygous females manifested higher decreases in PANSS depression factor compared to ACE-II homozygous and ACE-ID heterozygous females. The polymorphism's effect size was estimated as moderate to strong, while its contribution to the PANSS psychopathology ranged from ~5.4 to 8.7%, with the lowest contribution observed for PANSS positive score changes and the highest for PANSS depressive factor changes. Our results indicate that ACE-I/D polymorphism had a statistically significant but weak gender-specific impact on psychopathology data, and showed no association between ACE-I/D polymorphism and metabolic-syndrome-related parameters.


ABSTRACT Rejected a priori in the biomedical field as a category that has no meaning for clinical practice, race maintains an absent presence that spans techno-scientific productions and the daily practices of health professionals. Race constitutes a type of infrastructure that is rarely treated critically and that can be given as supporting evidence in scientific practices. It appears as an unexpected effect of biomedical technology that is actually centered around ideals of whiteness that it projects as universal. This exposes the limitations of biomedical technology to reach 'other bodies'—those that are not white – labeled as resistant to biotechnological intervention. By looking at ultrasound performance in diagnostic testing for glaucoma, this article discusses how whiteness, racism, and technological 'neutrality' are articulated in the materialization of race in diagnostic technological devices and health intervention in Brazil.


Where a party has presented reasonably available and plausible evidence in support of its claims and has, in substantiating those claims, specified evidence which lies in the control of the other party or a third party, the Court may on a reasoned request by the party specifying such evidence, order that other party or third party to produce such evidence. For the protection of confidential information the Court may order that the evidence be disclosed to certain named persons only and be subject to appropriate terms of non-disclosure.

ABSTRACT Global teacher shortage is a serious concern with grave implications for the future of education. This calls for novel ways of addressing teacher roles. The economic benefits of tireless labor inspires the need for teachers who are unlimited by natural human demands, highlighting consideration for the affordances of robotics and Artificial Intelligence in Education (AIED) as currently obtainable in other areas of human life. This however demands designing robotic personalities that can take on independent teacher roles despite strong opinions that robots will not be able to fully replace humans in the classroom of the future. In this article, we argue for a future classroom with independent robot teachers, highlighting the minimum capabilities required of such personalities in terms of personality, instructional delivery, social interaction, and affect. We describe our project on the design of a robot teacher based on these. Possible directions for future system development and studies are highlighted.


When a top revolves (Ω) in a circular orbit under universal gravitation in the direction opposite to the top spin (w) (ω > Ω), there is a chance that the spin axis will reverse from θ = 180° to θ = 0° and align with the vertical axis of revolution. In this paper we speculate that another external torque originates in the gyroscopic effect by revolution, an effect ultimately caused by axial precession Φ. We propose a satellite experiment to test the validity of this theory.


Previous studies showed that extracts of onion possess pharmaceutical properties that render them potential therapies for treatment of neoplastic, metabolic, immunological and infectious diseases. The latter include bacterial, parasitic, fungal as well as viral infections. To investigate the in vitro anti-bacterial activities of the aqueous extracts of fresh and powder onion and onion oil on a range of Gram-positive and Gram-negaive bacterial isolates. Anti-bacterial activities of onion were studied in light of its effects on the growth, motility, adhesion and biofilm formation in bacterial species of interest. Aqueous preparations and oil of onion were purchased from a retail food store at AlHilla town (2018). The extract of fresh onion was prepared and the powder onion was soaked as 30 gram of powder in 100 ml distillated water and allowed to stand for 72 hr. Then, it is sterilized by filtration (using Millipore 0.45 filter paper). Bacterial isolates (a total of nine Gram-negative and five Gram-positive isolates) were isolated from clinical samples. Agar well diffusion assay, tissue culture plate method (TCP) assay and bacterial ability to adhere to oral epithelial cell were used to evaluate the effects of onion on the growth, motility, adhesion and biofilm formation in bacterial species of interest. The findings of current study revealed that the aqueous extracts of fresh and powdered onion as well as onion oil have significant inhibitory effects on growth, motility, adherence and biofilm formation in the Gram-positive and Gram-naegative bacterial isolated considered in current study. These preparations could be useful alternatives for commonly utilised synthetic agents for treatmnet of multi-drug resistant bacteria. However, the exact mechanism(s) behind the observed antimicribial effects of onion needs further exploration and specification, maybe at the molecular level. In addition, in vivo studies involving humans and / or animals are needed to confirm the observed effects of onion. Keyword: Antimicrobial activity, Anti-adherence, Anti-biofilm and Anti-motility, Extract of Onion, Allium cepa. INTRODUCTION Onion (Allium cepa) is a bulbous plant grown in nearly every country in the five continents [1]. In addition, the reproduction, transport and storage of onions are quite easy. It has been shown that onions have particular medicinal uses both in conventional and modern medicine as they are effective in the treatment of diseases affecting cardiovascular, respiratory as well as musculoskeletal systems [2; 3]. Onions contain carbohydrates, proteins and minerals (such as sodium, potassium and phosphates). In addition, they contain secondary metabolites that exert in vitro antibacterial activities such as tannins, terpenoids, alkaloids and flavanoids [3; 4]. Also, onion bulbs contain a wide range of phytochemicals, most of them are hydrocarbons and their derivatives, such as dipropyl disulphide, Allicin, diathyl sulphide, dimethyl disulphide, mercaptopropane or propylmercaptan [5; 6; 7]. Previous studies showed that extracts of onion possess pharmaceutical properties that render them potential therapies for treatment of neoplastic, metabolic, immunological and infectious diseases [8; 9]. The latter includes bacterial, parasitic, fungal as well as viral infections [8; 10-13]. For example, onion extracts showed antibacterial activity against Vibrio cholera [1]. Another example, alcoholic and aqueous suspensions of dried onion bulbs exhibited inhibitory effects against the growth of Gram-positive bacteria such as Staphylococcus aureus [14] and Bacillus subtilis [15]. In addition, the fresh juice of onion (Allium cepa) showed significant inhibitory effect against the growth of a range of multidrug resistant bacteria [16]. Moreover, extracts of onion showed concentration-dependent reduction in the population of bacteria associated with ophthalmic infections [17]. Bacterial motility is a feature of Gram-negative as well as Gram-positive bacteria [18; 19]. It is an activity in which bacteria quickly move on wet surfaces in a synchronized way, however, it does not begin unless bacteria attain certain population. The development of this activity includes the detection of a suitable physical and chemical signals from the surrounding with the resultant production of elongated (due to inhibition of bacterial division) and flagellated cells, synchronized progression of these cells and consolidation to vegetative cells and beginning of a fresh cycle [18; 19]. Bacterial motility is genetically controlled and associated with their biofilm formation with subsequent resistance to antibacterial agents [20-22]. In addition, it is influenced by availability of exterior nutrients, humitidy of the surface and presence or absence of chemical agents such as surfactants and antiseptics. On the other hand, biofilms are means by which bacteria can resist environmental challenges and stay alive for a long time by being firmly attached to the host surfaces [23; 24]. In these biofilms, bacteria find accommodation in a milieu composed of sugars, proteins and nucleic acids. Biofilms formation is a feature of chronic bacterial infections where they (bacteria) become multi-drug resistant and can not be attacked by immune cells of the host with subsequent augmentation of economic burden due to frequent admissions to hospital [8]. For example, catheter-related infection of the urinary tract and the subsequent formation of biofilm by Proteus species are triggered by swarming activity of these microorganisms [20]. Moreover, many antibacterial drugs are virtually ineffective against biofilm cells as compared to the more sensitive planktonic cells. Bacterial cells are capable of producing multi-layer biofolms with the greater numbers of cells in the upper and lower layers, while water channels (in between) are to convey nutritional elements and waste products [25]. Moreover, there are two cell-surface attached organelles responsible for bacterial motility and biofilm formation. These are the flagella and type IV pili (26). They have been shown to facilitate bacterial association with host surfaces [26]. In addition, when environmental factors are optimal, bacteria will continue their progression as well as cellular division and eventually formation of horizontal and homogeneous biofilm; otherwise the latter will be consisting of cellular collections [27]. As a result, bacterial swarming and biofilm formation are inter-related and, therefore, pharmaceuticals that can antagonize the former will indirectly prevent formation of biofilms and prevent the development of multi-drug resistant bacteria [28].

The peculiarities of the phase dynamics of stacks of coupled Josephson junctions with topologically trivial and nontrivial barriers have been investigated numerically and their comparative analysis is carried out. The effect of coupling and dissipation parameters on the parametric resonance in the breakpoint region is shown. It is found that the dependence of the breakpoint voltage on the dissipation parameter demonstrates a minimum due to the changing of frequency of longitudinal plasma wave. We have shown that in case of the stack with nontrivial barriers the observed minimum shifts along the $\beta$ to the $\sqrt{2}$ in comparison with trivial barriers stack. We assume that the found features may be used for the experimental determination of Majorana fermions in the stack of JJs with the nontrivial barriers.


The presence of heterogeneities in solids very frequently leads to the generation of eigenstresses and stress concentrations. Examples are ceramic materials reinforced with Zirconia particles which undergo phase transformations accompanied by a change in shape and volume, Ni-base superalloys where a so-called γ'-phase forms in a γ -phase matrix, or the formation and accretion of pores in metals subjected to heavy loading. This paper shows how discrete Fourier transforms (DFT) can potentially be used as an effective tool for the mathematical analysis of stresses arising in heterogeneous materials and of the phenomena associated with them.


The stability of the bright-type algebraic solitary-wave solutions of two extended nonlinear Schrodinger (NLS) equations, recently obtained by Hayata and Koshiba (HK) [Phys. Rev. E 51 (1995) 1499], is investigated by means of the averaged Lagrangian variational technique. Concerning the first equation (a quadratic-cubic NLS eq.), the variational analysis shows that the exact solution found by HK is stable, as solitary-wave initial conditions which deviate from the HK solution evolve into oscillatory functions whose envelopes remain close to the exact solution, if certain stability conditions are satisfied. Concerning the second equation (a cubic-quintic NLS eq.), the variational analysis indicates that in this case the exact solution is unstable, as solitary-wave initial conditions which are higher than the exact solution lead to a blowup within a finite distance, whereas initial pulses which are lower than the exact solution are completely dispersed.


We consider a class of minimal abelian extensions of the Standard Model with an extra neutral gauge boson $Z'$ at the TeV scale. In these scenarios an extended scalar sector and heavy right-handed neutrinos are naturally envisaged. We present some of their striking signatures at the Large Hadron Collider, the most interesting arising from a $Z'$ decaying to heavy neutrino pairs as well as a heavy scalar decaying to two Standard Model Higgses. Using renormalisation group methods, we characterise the high energy behaviours of these extensions and exploit the constraints imposed by the embedding into a wider GUT scenario.

The use of direct sequence pseudonoise (DSPN) signalling to mitigate the fading caused by very dense scatterers in the mobile communication environment is explored for the specific case of a rectangular signal spectrum. A very simple and revealing relationship emerges between the variability of the signal strength and the signal bandwidth.


The smart phone application (APP) market surges as the smart phones emerge as one of the most important consumer electronic devices during the past years. The total download numbers of APPs have reached 17.7 billion in 2011, which was doubled from 8.2 billion in 2010. In the foreseeable future, this mega trend continues. Thus, developers began to develop APPs on various platforms. The word-of-mouth marketing ((WOMM, WOM marketing) can improve APPs' exposures to customers and increase users' download rates and purchase intentions, as well. Though WOMM has become a new smartphone APP marketing promotion strategy, few scholars intended to explore factors influencing the definition of WOMM strategies. Thus, the authors intend to derive influences of the WOMM on mobile phone APPs by using the Fuzzy Decision Making Trial and Evaluation Laboratory (Fuzzy DEMATEL) and the Analytic Network Process (ANP). An empirical study based on a Taiwanese App developer was introduced for verifying the analytic framework. Based on the empirical study results, the recipients' capabilities of searching information, relationships between the message receiver(s) and communicator(s), as well as opinion leader's viewpoints are the most important factors influencing the WOMM strategies of Smart Phone APPs.


As the borders of Europe slowly expand to include Turkey, the country finds itself in the position of having to strengthen its own walls. With the continuing conflict in Syria, this issue has become urgent. Merve Bedir traces the last 100 years of migration in Turkey, and how it has dealt with varying flows of refugees and immigrants. Away from the refugee camp with its clear borders and rations, Bedir questions the condition of the urban refugee, a precarious existence within a state of exception, and to what degree resistance might be possible.


The pattern of potassium uptake by the rice crop in its growing period and the dynamics of potassium in purple soil were studied. Uptake of K by the rice plants rose steadily after transplanting, reached the maximum in 45 days and dropped gradually thereafter. The content of readily available K and non-exchangeable K in the soil remained little changed in the 0~30 days after transplanting, decreased markedly in the 30~45 days, rose again after that, reached the maximum on the 75 th day after transplanting and remained relatively stable thereafter.


This project consists of developing an Android application that uses a device to detect the heart rates and calculate the variability of the heart rate and through these values the stress level and the sleep quality of the user is calculated and the objective of the application is recommend breathing exercises to recover from stress. And to achieve this goal of the Android application, several prototypes were implemented separately, one of them is the remote server where it contains the data base, through this module it allows users to save data in the network and in this way the application becomes multi-user And the other modules of the project is the generator of HRV values, which these values will go directly to the data base. And the generator of the JSON model that uses the data base data to be able to generate the models, the generated JSON models will be used in the Android application to be able to simulate HRV values. These two generators were basically implemented to be able to simulate a device that detects heart rates since in the end we can not get this device. Keywords– Android, sleep quality, stress, heart rate, HRV generator, Laurea, MySQL, PHP, Polar, Bayesian network, UAB, XAMPP.


Background: Nepal is a landlocked and developing country with 34.6% children under 14 years of ageas well a big population under the line of poverty. Socioeconomic status, family type, overcrowding and provision of health care facilities act as risk factors for ENT disorders. There is a lack of data on pediatric ENT disorders from various Nepalese populations. This study was undertaken to determine the hospital prevalence of ENT disorders in pediatric population and their relationship with sociodemographic factors.Objectives:This study was undertaken to determine the hospital prevalence of ENT disorders in pediatric population and their relationship with socio-demographic factors in a tertiary care hospital in Nepal.Methods: This is a prospective analytic study, conducted at Department of ENT, Head & Neck Surgery between January 2010 and December 2010 in the Ear, Nose and Throat (ENT) Department, Gandaki Medical College Charak Hospital, Pokhara, Nepal. All patients aged 16 years or younger presented ear diseases to the ENT clinic of the hospital seen by ENT surgeons were enrolled into the study.Results: Among 1632 children, ENT diseases were found to be more common among male children (60%). The male to female ratio is 1.5:1. Most of the children were living in joint family (64.16%). Diseases of auditory system (57.84%) were the most common group of ENT problems among the pediatric population, followed by pharyngo-esophageal (23.53%) and nasal disorders (18.63%). Most common otologic disorder was ear wax (40.9%). Among problems associated with nose, rhinitis (23.4%) was most common. Pharyngitis was troubling (44.8%) of our study population.Conclusion:Improvement of health education, socioeconomic status and health facilities will be helpful in reducing the prevalence of ENT diseases. A study on the prevalence of the Ear Nose throat and Head and Neck diseases in developing country like Nepal can provide basic data which can be relevant and beneficial to the development of medical ENT curriculum in the regional setup and subsequent medical practice.


Abstract The effect of palladium metal on the performance of a CuO–ZnO–Al 2 O 3 catalyst is studied for methanol synthesis by hydrogenation of carbon dioxide. The dramatic decrease in the methanol yield (in mol CH 3 OH/h·g cat ) seen for the Pd-containing catalysts is discussed in terms of formation, decomposition, and reconstruction of hydroxycarbonate precursors. The CuO–ZnO–Al 2 O 3 mixed oxide, obtained by calcination (673 K) of a hydrotalcite-containing precursor, still contains interlayer CO 3 2− anions as a result of incomplete decomposition. The presence of the remaining carbonate anion and the hydrothermal-like treatment during the Pd impregnation step allow the partial reconstruction of the original hydrotalcite-type structure. An improvement in the crystallinity of the copper oxide phase is also obtained. This improvement in crystallinity occurs during the hydrotalcite reconstruction and is a consequence of crystalline rearrangement of this oxidic phase. Such an effect gives rise to poorer copper dispersion and, consequently, to an apparent masking of the promoting effect of palladium. However, nitrous oxide chemisorption measurements allow the redefinition of the methanol yield per mole of exposed copper, a situation that clearly reveals the intrinsic promoting effect of palladium. The appearance of low-temperature reduction peaks involving Cu(II) species and the increase in the hydrogen consumption for the Pd-modified catalysts, both compared to the base CuO–ZnO–Al 2 O 3 catalyst, indicate a hydrogen-spillover mechanism as being responsible for the intrinsic promoting effect of palladium.


This paper presents a method of analysing the performance of M-ary coherent phase-shift-keyed (c.p.s.k.) signals transmitted through a bandpass nonlinearity, exhibiting a.m./a.m. and a.m./p.m. conversions, and in the presence of additive Gaussian noise both preceding and following the nonlinearity. The method is computationally superior to those previously obtained by other workers, especially for high-level (M > 4) c.p.s.k. systems. In addition, it is capable of extension to include other signal corruptions, such as cochannel interference, both preceding and following the nonlinearity.


Stop 46,000,000 SLC1A2 BDNF In the article of Xu et al. 'Characterization of 11p14-p12 deletion in WAGR syndrome by array CGH for identifying genes contributing to mental retardation and autism' (Cytogenet Genome Res 2008;122:181–187) some errors occurred. In table 1, patient F8a, the deletion size should be 11.5 Mb and the end point should be 36613661; patient F11a, the deletion size should be 2.6 Mb. Table 2 and figure 2 have been revised accordingly (see revised table 2 and figure 2). The size of deletions mentioned in the 'Abstract' and 'Results' should read ranging from 2.6 to 23 Mb. In the 1st paragraph of 'Materials and Methods', the number of the patients diagnosed with autism should read 14. In the 1st paragraph of 'Results', the ratio of male/female should read 10/6 in +ASD and 4/11 in –ASD; in the 4th paragraph of 'Results', patients who had deletion of both BDNF and SLC1A2 but no autism who were mosaic should be 1/5. The changes have led to some minor difference in statistics but not a significant difference in P values, and therefore revision of all the numbers and percentages of deletion mentioned in the text is not considered necessary.


An effective phenol-degrading yeast strain was isolated from phenol-contaminated soil. According to morphological, physiological and its 26S rRNA gene sequence, it was identified as genus Trichosporon sp. strain and named TX1. Its optimal conditions for grow th and degradation were 30℃, pH 7.0, 150 r·min-1 of shaking rate. The preliminary study on the metabolic pathway of phenol about this strain indicated that, the phenol hydroxylase in the cell membrane and cytoplasm transformed phenol into catechol firstly; and then ortho aromaticring cleavage was carried out by the catechol 1, 2-dioxygenase (C12O), being an inducible intracellular enzyme.


In this study, Excitation Emission Fluorescent matrix (EEFM) integrated with Parallel factor analysis (PARAFAC) was applied to investigate the variation of organic property in Donggang River located in Southern Taiwan between Oct. 2010 and Oct. 2015. It reveals that both values of BOD5and COD had a closer proximity at twice samplings; however, the four main components in both samplings showed a different location of excitation and emission wavelengths. On Oct., 2010, EX/EM (percentage of area) of four components were respectively 320/410 nm (46 %), 370/460 nm (27 %), 290/350 nm (14 %) and 280/450 nm (13 %) mainly belonging to humic-like substance. Regrading to the result on Oct, 2015, 320/420 nm (29 %), 228,278/358 nm (29 %), 240/420(29 %) nm and 228/310 nm (14 %) were found attributed in amino organic substance with low excitation wavelength. On Oct.2015, the intensities of four main components in Cinsheda Bridge higher than those in other locations may be attributed with of heavily polluted source like piggery wastewater. For the partition of N-organic and C-organic, there had a significant change on both samplings.

The study of local dissipative processes by the method of free-damped torsional oscillations excited in polyvinyl alcohol (PVA) showed the presence of three loss peaks in the internal friction spectrum in different temperature ranges of this spectrum [1].


Three primers,TX1,TX2 and TX3 were designed using Primer Premier 5.0 according to 529bp sequence from RH strain of T.gondii for the establishment of the hemi-nested PCR.Combining the product of PCR with the primers TX1 and TX3 to PMD18-T vector for sequencing.The product of the hemi-nested PCR was about 350bp long and the product of primer TX1 and TX3 was about 520bp long,The 521bp fragment ligated to the pMD18-T vector was 100% identical to the published 529 sequence(AF146527).The special test showed that no fragment was amplified using DNA of Neospora caninum,Cryptosporidium bovis,Babesia bovis,Theileria,annulata,Streptococcus bovis,Streptococcus suis,Enterococcus mundtii.Result of sensitivity showed the detection limit of the method was 20fg DNA.Three soil samples were detected positive among 22 soil samples using the detection method.


The objective of the following article is to consider the methodological option for developing a multidisciplinary approach concerned with already established intuitive behavior of using mobile technologies. Aligning methodologically to 21st century real life, digital fluidity is our compass-on-the-go by approaching life cycle didactics. The FIRST LIFE CYCLE has been focused on introducing the new 'immersive methodology'. This has been conveyed by the design and the start of a step-by-step procedure in two interdisciplinary BA Minor programs at NBU (Digital Humanities and Service Delivery Engineering). They both are focused on the dynamic intersection of technological and psychological multi-skills. The SECOND LIFE CYCLE is to expand methodologically and reach the mental dynamics of a Creative Lab. The THIRD LIFE CYCLE is to further the established infrastructure of "light project-based activities" between WSU and NBU students to the level of IMMERSIVE GAME TECHNOLOGY guided by their variously oriented lecturers where grown-up-digitally students and digitally migrated research fellows experience innovative cutting edge technologies and gain relevant philosophical insights. In this 'interdisciplinary infrastructure' an inherent place is provided to lecturers-representatives of global market players. Finally, all these lead to the natural acquisition of fine-tuned skills, while working in a team with different specialists, and being guided by experienced lecturers from NBU, TU Sofia, Western Sydney University and multinational companies like IBM, HPE / Micro Focus, Unify / Atos, Bosch Software Innovations. An additional methodological acquisition is the way students develop useful "social technologies" wherein emotional sensitivity and intuitive use are of particular importance. Thus both programs master a permanently aligning blended educational approach, combining traditional learning capstones with social networking models tailored for the growing target group of grown-up-digitally students. As a result, hybrid Minors at NBU become the "best practice" of testing a realistically developed educational model where outcomes and curriculum changes can always take place, being updated and upgraded whenever necessary.

It is an irony of evolutionary genetics that, although it is a fusion of Mendelism and Darwinism, it has made no direct contriba-tion to what Darwin obviously saw as the fundamental problem: the origin of species. I do not mean to say that the theory and observations of population genetics have not influenced and even permeated theories of species formation. One has only to read Dobzhansky's Genetics and the Origin of Species (1951) or Mayr's Animal Species and Evolution (1963) to see how population genetics informs modern ideas about speciation. Mayr's whole thesis, that speciation is the tearing apart of a group of genetically interconnected populations, normally held together by strong cohesive forces of migration and natural selection, comes directly out of the balance school of population genetics, which he has assimilated into the theory of geographic speciation. But it is a long way from describing speciation in general genetic terms to constructing a quantitative theory of speciation in terms of genotypic frequencies. While it is a question of elementary population genetics to state how many generations will be required for the frequency of an allele to change from q1 to q2, we do not know how to incorporate such a statement into a speciation theory, in large part because we know virtually nothing about the genetic changes that occur in species formation. How much of the genome is involved in the early steps of divergence between two populations, causing them to be reproduc


This paper describes an effective approach for ambiguity resolution on the tly (OTF)-the Fast Ambiguity Search Filter (FASF)--and presents comparative numerical results for this method and the least-squares search approach. In the past, the search range of each ambiguity parameter was determined separately regardless of the assumed integers of the other ambiguities. In the new approach presented here, the search range is determined recursively for each ambiguity parameter. The effect of an assumed integer on other ambiguities is then fully taken into account when determining the uncertainty range of an ambiguity parameter. Another important characteristic is that all observations from the initial to the current epoch are taken into account through the use of a Kalman filter. An index of possible inability to fix the ambiguities is used. Therefore, a full search of all possible integer ambiguities is not required, and the computation is dramatically reduced. Computer memory is also saved since there is no need to retain all potential solutions. Test results show that both the computation time for ambiguity search and the observation period required for ambiguity resolution are significantly reduced.


This article focuses on how fans/consumers are unofficially involved in the promotion of an audiovisual brand, through a unified management design, what I call "joint brand management." The proposed term describes how both production companies and brand/fan communities simultaneously contribute to the development, establishment, and expansion of a brand through a combination of conventional brand management strategies and unofficial content created by fans/brand enthusiasts.


This paper casts an application of an extended fuzzy integral on the selective extraction of color clusters characterized by a particular color hue from color document images. Despite of the negative role of fuzzy integral, the presented approach attains the detection of the seals through the neighborhood information via the center of area method. The conventional fuzzy integral evaluates the negative aspects of the importance about the items by min operator, which result in the discontinuous parts of seals. In an attempt to cope with the drawback our approach considers the integral aspects via the center of area method, which results in the robustness of the images. Finally, the framework is successfully tested on a data set formed by documents from a real application for the detection.


During the last few decades the wasp-like spider Argiope bruennichi Scopoli, 1772 expanded its wide geographical distribution in Europe. In this paper we describe and test differences in the diet composition of the wasp-like spider inhabiting a river valley (traditional habitat) and xerothermic grassland (new habitat) in Poland. From a total of 163 webs of A. bruennichi, 430 prey items were found, mainly insects : Coleoptera, Diptera, Homoptera, Heteroptera, Hymenoptera, Lepidoptera, Mecoptera, Odonata, Orthoptera and Neuroptera. Moreover, a semi digested specimen of the common frog Rana temporaria was recorded. Habitats differed significantly in the percentage distribution of eleven general food categories. Among potential influencing factors the number of caught prey was correlated only with the height of the web hub above the ground. The wasp-like spider is ecologically flex- ible in the use of novel food spectra and this probably allows the colonisation of new localities, as well as habitats.

Abstract : This study focuses on the emerging technologies used in Augmented Reality (AR) and their role in the field of education. With this aim, 70 articles gathered from Scopus, Science Direct, Springer, Taylor Francis, and Web of science databases were examined. Analysis showed that the number of AR articles in educational environments have gradually increased over the years. AR is being most commonly used in science education (biology, physics and chemistry). The literature also highlights various advantages of AR when used in learning environments. It has been understood that the AR is an imminent learning tool and is lately gaining recognition and acceptance in the educational field. While marker-based AR was the key in most of the articles, it was implemented using mobile devices. The literature revealed that most articles examined their results using Quantitative methods. Our article emphasizes on the impact of AR in education, current technologies and its future scope. This paper also provides detailed analysis of the use of AR in engineering education highlighting that the most of the articles highlighted the use of marker-based AR, used non-probability sampling strategy and appliedmixed method for analysis. The findings of this study would help other researchers to identify potential direction for future research. Keywords : augmented reality; education; interactive learning environment; technologies of augmented reality; augmented reality integration.

The problem of data aggregation for binary event detection using wireless sensor networks has been considered in the present work. We propose a novel multibit adaptive aggregation scheme (MAAS) which combines the merits of both multibit and adaptive aggregation schemes. Firstly, being adaptive, the proposed scheme does not require knowledge of the performance indices of sensor nodes as required by the existing optimum decision fusion rule. Therefore, in case of small variations in the topology or performance indices, the proposed scheme needs to just fine tune the weights starting from the previously adapted weights, instead of seeking new values of the parameters or recomputing the initial setup. Secondly, being a multibit aggregation scheme, the performance of the proposed MAAS is higher than the existing single-bit aggregation schemes at a cost of communicating only a few extra bits. This makes it suitable for event detection applications where detection accuracy is more important than the energy drained in communicating a few additional bits. Further, the performance of the proposed MAAS is shown to be consistently superior to single-bit schemes even in the presence of Rayleigh fading channel.


This dissertation investigates how second language (L2) speakers perceive non-native speech and how language learners can be helped to better perceive differences between their L2 output and target language speech, thus facilitating improvements in pronunciation.

Study 1 investigated which dimensions underlie the perception of L2 speech by L2 listeners. Fifteen L2 listeners (and 10 native English listeners who served as a baseline group) rated 30 L2 audio-recordings from controlled reading and interview tasks for dissimilarity, using pairwise comparisons. Multidimensional scaling analyses revealed that fluency and global aspects of the speakers' pronunciation explained listener judgments but that there was little agreement across the L2 and native listener groups.

Study 2 investigated the role of language background in comprehensibility judgments. English speakers from Mandarin, French, Hindi, and English language backgrounds (10 per group) rated the speech of 30 L2 speakers from the same language backgrounds for comprehensibility and provided verbal reports about each rating. They then rated the speakers for segmental and word stress errors, intonation, and speech rate. Correlations between the speech measures and comprehensibility ratings for each L2 listener-speaker group and hierarchical regressions carried out for each L2 listener group revealed that different speech measures contributed to comprehensibility for different listener-speaker groups, with language background accounting for an additional six percent of the variance in comprehensibility ratings for the Mandarin listeners after the linguistic variables were taken into account. Analysis of the verbal reports for whether the listeners attributed their ratings to the speakers' language background showed only a moderate relationship to the quantitative data.

Study 3 investigated the efficacy of shadowing, a common pronunciation practice technique. Sixteen learners practiced shadowing with iPods for eight weeks. Two language tasks (shadowing task, extemporaneous speaking task) were administered as pre-, mid-, and post-tests, and were rated by 21 L1 English listeners. The shadowing task was evaluated for the learners' ability to imitate a speech model, and the extemporaneous speaking task was rated for comprehensibility, accentedness, and fluency. Results indicated that the learners improved significantly in all speaking measures apart from accentedness and were largely positive about the activities.


The design of two-dimensional (2-D) filter banks yielding orthogonality and linear-phase filters and generating regular wavelet bases is a difficult task involving the algebraic properties of multivariate polynomials. Using cascade forms implies dealing with nonlinear optimization. We turn the issue of optimizing the orthogonal linear-phase cascade from Kovacevic and Vetterli (1992) into a polynomial problem and solve it using Grobner basis techniques and computer algebra. This leads to a complete description of maximally flat wavelets among the orthogonal linear-phase family proposed by Kovacevic and Vetterli. We obtain up to five degrees of flatness for a 16/spl times/16 filter bank, whose Sobolev exponent is 2.11, making this wavelet the most regular orthogonal linear-phase nonseparable wavelet to the authors' knowledge,.


Objective
To investigate job satisfaction and influencing factors of medical staff in China.

Methods
From December 2017 to January 2018, based on the third round third-party evaluation of the Healthcare Improvement Initiative, data on job satisfaction of medical staff at 136 tertiary public hospitals in 31 provinces of China were collected.Chi-square test and binary multivariate logistic regression were used to analyze the influencing factors of job satisfaction.

Results
The job satisfaction of medical staff at 136 sample hospitals was relatively low.34.6% of the doctors were satisfied with their job, while the corresponding rate in the nurses was 48.7%.Multi-factor analysis showed that income level, workload, doctor-patient relationship, hospital′s compensation policy, and promotion policy were all significant factors influencing medical staff′s job satisfaction(workload OR 1, P<0.05).

Conclusions
Improvement of the medical staff′s job satisfaction depends on optimizing their income distribution policy, increasing their income, improving the promotion policy of professional titles, reducing their workload rationally and building a harmonious relationship between doctors and patients.

A phase with the stoichiometry Ni0.5(Al0.5−xMnx) is observed at heterophase interfaces of Cu-rich precipitates in an α-Fe matrix, utilizing atom-probe tomography. First-principles calculations are utilized to determine the substitutional energies, yielding EMn→Ni=0.916eVatom−1 and EMn→Al=−0.016eVatom−1 indicating that the manganese atoms prefer substituting at Al sublattice sites instead of Ni sites. A synchrotron radiation experiment demonstrates that the identified phase possesses the B2 structure.


Based on the theory of coal or rock damage and the character of coal or rock connatural lacuna, a acoustic e-mission( AE) mathematical model describing the variation of rock damage is established, and theorize the relation between the rate of AE and the process of strain, the rate of strain, coal or rock uniformity, original damage, material connatural character, and so on. This model agree quite well with test results in lab. By inferring, computer simulating and testing in lab, the rate of the rock of different uniformity have three mode during the strain; ( power) ascending mode, calm mode and ascend-decending mode. While we hold the material damage rule, We can judge the material damage development according the AE character of real solid material in engineering application. 4figs. ,8refs.


As a part of agricultural negotiations, the WTO members have agreed to phase out all forms of export subsidies. This study evaluates the current level and commitments of subsidised export quantities and subsidy expenditures of the EU, which is by far the largest user of export subsidies. The effects of removing subsidies are studied by a multi-region general equilibrium model GTAP on world-wide, EU wide and on the level of the Finnish agriculture. The results show decreasing prices and production in the EU for subsidised products especially in dairy, grain and meat production and slight increases in their world market prices. The effects for Finland are magnified compared to the rest of the EU and are seen especially in grains production.

Community structure of bivalvia and gastropods nearby water vegetation in Sentani Lake, Papua. Line's transect and plot methods were used to determining the structure of mollusks and vegetation by using index, diversity, and dominance as parameters. Intentional measurement were carried out on several biological parameters of the waters at 10 sampling points. From the observation and measurments, we obtained seven types of mollusk with 5644 individuals, where six types are belong to gastropods and one type is a member of bivalves. The highest level of mollusk diversity was in Kwadeware, the highest at the inlet of the lake, and were dominated by Melanoides tuberculata and Pomacea canaliculata. In addition, vegetation found in the area observation were water hyacinth (Eichhornia crassipes), water spinach (Ipomoea aquatica), apu wood (Pistia stratiotes), genjer (Limnocharis flava), Hydrilla verticillata, seagrass (Potomogeton malainus), Nymphaea alba, Ceratophyllum demersum, and Nymphoides indica.Key words: gastropods; molluscs; vegetation; Sentani lake


rogated not only to confirm its content but also to understand why it was generated. The stories Woodward and Bernstein wrote might have been different, at least in tone, had they asked themselves why Felt was giving them specific items of information. This work generated an interesting response among journalists. That journalists had broken the Watergate story became an important feature in journalists' self-definition. Holland gives journalists a smaller role than that. In response, leading journalists circled their wagons. Leak was not widely reviewed in major publications, and many reviewers disparaged Holland for underplaying journalists' role in exposing the scandal or at least in keeping the story alive until its political effects could take hold. Leak is an engaging read, but may end up as a long footnote to the Watergate story as a whole.


PREMISE
The sporoderm of seed-plant pollen grains typically has apertures in which the outer sporopollenin-bearing layer is relatively sparse. The apertures allow regulation of the internal volume of the pollen grain during desiccation and rehydration (harmomegathy) and also serve as sites of pollen germination. A small fraction of angiosperms undergo pollination in water or at the water surface, where desiccation is unlikely. Their pollen grains commonly lack apertures, though with some notable exceptions. We tested a hypothesis that in some angiosperm aquatics that inhabit water of unstable salinity, the pollen apertures accommodate osmotic effects that occur during pollination in such conditions.

METHODS
We employed microscopy techniques to examine the tepaloid clade of the monocot order Alismatales, which contains ecologically diverse aquatic and marshy plants. We used Ruppia as a model to test pollen behaviour experimentally in water of various salinities. Pollen aperture evolution was analysed using molecular tree topologies.

RESULTS
Phylogenetic optimisations demonstrated an evolutionary loss and two subsequent regains of the aperturate condition in the tepaloid clade of Alismatales. Both of the taxa that have reverted to aperturate pollen (Ruppia, Ruppiaceae; Althenia, Potamogetonaceae) are adapted to changeable water salinity. Direct experiments with Ruppia showed that the pollen apertures have a role in a harmomegathic response to differences in water salinity.

CONCLUSIONS
Our results showed that the inferred regain of pollen apertures represents an adaptation to changeable water salinity. We invoke a loss-and-regain scenario, prompting questions that are testable using developmental genetics and plant physiology. This article is protected by copyright. All rights reserved.


To provide basic data for developing mixing details and design models for structural heavyweight magnetite concrete, 18 concrete mixtures were prepared under different replacement levels with natural sand and granite coarse particles for magnetite fine and coarse aggregates, respectively. The density of concrete ranged between 3182 and 3400 kg/m³ (197.28 and 210.8 lb/ft³) for replacement by natural sand, and 2446 and 3118 kg/m³ (151.65 and 193.31 lb/ft³) for replacement by granite coarse particles. Test results revealed that the replacement by natural sand was preferable to that by granite coarse particles for enhancing the initial slump, tensile resistance capacity, shear strength and bond behavior with a reinforcing bar of heavyweight magnetite concrete, and for minimizing the decrease in concrete density due to replacement by normal weight aggregates. ACI 349 equations for moduli of elasticity and rupture were generally conservative for heavyweight magnetite concrete. The CEB-FIP equations were not conservative for the moduli of elasticity and rupture, strain at the peak stress, and splitting tensile strength of heavyweight magnetite concrete, whereas they were conservative in predicting the bond stress-slip response of heavyweight magnetite concrete. Overall, it can be concluded that the density of concrete should be considered as a critical factor, together with its compressive strength, in determining the various mechanical properties of heavyweight concrete.
