Let M be a (2 + v) -dimensional Riemannian manifold of constant curvature c_ and M be a 2-dimensional Riemannian manifold immersed isometrically in M by the immersion_ x: M^M. F(M) and F(M) denote the orthonormal frame bundles over M and M respectively. Let B be the set of all elements b = (p, eίy ez, es, •••, e2+v) such that (p, elt ez)eF(M) and (p, eίt e2, e ό, •••, ez-rv)^F(M) identifying p$M with x(p) and βι with dx(eϊ), i = 1, 2. Then B is naturally considered as a smooth submanifold of F(M). _Let ώA, ^AB— —U>BA, A, B=l, 2, 3, •••, 2 + ι^, be the basic and connection forms of M on F(M) which satisfy the structure equations:


Objective To evaluate the relationship between Pgp expression, chemotherapy and clinical prognosis of advanced colorectal cancer. Methods 44 cases of advanced colorectal cancer underwent surgical operation. Immunohistochemistry technique was used to detect the Pgp expression. All cases were under careful follow up. Results 24 of 44 cases (54.5%) showed Pgp positive expression. The cases with no less than 2 times of chemotherapy had a higher proportion of Pgp positive expression than the rest cases, and the patients with Pgp positive expression had poorer prognosis. Conclusion MDR existed in colorectal cancer patients after chemotherapy and closely related to clinical prognosis.


A 43-year-old man with uncontrolled hypertension presented with a sudden headache and right homonymous hemianopsia. A brain CT revealed intracerebral hemorrhage, and an MRI examination demonstrated a hyperintense lesion on T2-weighted sequence in the splenium of the corpus callosum (Figure). Brain CTA and MRV were unremarkable. Etiologic workup in the blood and CSF was unrevealing. Sixteen days later, the hemorrhage was smaller and the splenial lesion disappeared completely (Figure). Reversible splenial lesion syndrome (RESLES) usually results from antiseizure medication withdrawal, infection (particularly influenza virus), severe hypoglycemia, and hypernatremia.1 The clinical manifestation of RESLES is nonspecific, mainly related to the concurrent event, and callosal disconnection syndromes have not been reported. RESLES represents a specific clinicoradiologic syndrome with a favorable prognosis, and repeated MRI is important to determine whether the lesion is transient. In this case, the splenial cytotoxic lesion may be associated with transient hypoperfusion resulting from the compressive effect of hemorrhage.2


To verify the likelihood of a new solar system formation hypothesis, research was conducted into a possible low speed, shallow angled collision between an ice-covered Earth and Moon, 4.1 billion years ago. Via a tailored set of indicators, not just one but three collisions were identified beyond a reasonable doubt. All are presented in great photographic and topographic detail in this paper. On the Moon, the three impact areas are: Aitkin basin, a double string of major maria and wider Oceanus Procellarum. On Earth, the respective corresponding impact areas are: The Arctic, the Canadian Shield and equatorial Gondwana (centred at current Antarctica). As a result, many issues in geology can now be explained, from the 'faint young Sun paradox' to Hadean geology and continental drift.


The issue of floods in Australia is receiving increased researchers' attention. Floods normally occur when some part of the country experiences high level of precipitation for a certain period of time. Natural disaster protection plans, which have flood


H diffusio n constants have been determined from steadystate fluxes through Pd–Ag alloy membranes. The upstream side is maintained at a nearly constant p up and, consequently at nearly constant r up =H/(Pd 1-x Ag x ), and the downstream side at p H 2 ≈0 (r down =0) (423 to 523 K). It is shown that the permeability is a maximum for atom fraction X Ag =0.23 at 423, 473 and 523 K at both p up =20.3 and 50.5 kPa. At finite H concentrations non-ideality can be a factor and if concentration -independent diffusion constants, D * , are desired the following equation for the flux is appropriate,


ABSTRACT Most school counseling site supervisors have not received training in clinical supervision despite regularly serving as supervisors for school counseling students. In this article, we describe how one university has created a clinical faculty supervision training program for school counselors to address this need. The program infrastructure, training activities, session content, and evaluation methods are described. We present informal program evaluation data (N = 19) assessing participants' perspectives of the program and discuss implications for supervision training.


OBJECTIVE: To examine the safety and efficacy of intraarterial and endovascular treatment for acute ischemic stroke (AIS) due to dissection.
BACKGROUND: Carotid and vertebral artery dissection should not be considered a contraindication for intravenous tPA treatment. Few studies report safety and efficacy of intraarterial thrombolysis or endovascular treatment for dissection.
DESIGN/METHODS: We studied consecutive admissions with AIS to our Comprehensive Stroke Center from 2012-2013 who received intraarterial thrombolysis or an endovascular procedure ("aggressive therapy"). We examined differences in adverse events, defined as in-hospital death and symptomatic ICH (sICH), and favorable outcome, defined as Modified Rankin Score (mRS) ≤2 at discharge and 3 months, for AIS patients who presented with mechanism of dissection vs. other cause.
RESULTS: Of 1,320 patients with AIS, 173 patients received aggressive therapy and comprise our study population: 15 with dissection (8.7[percnt]: 11 carotid, 4 vertebral) and 158 without dissection (91.3[percnt]). Stroke severity was similar with vs. without dissection (mean NIHSS: 15.4 vs. 17.2, p=0.29). There were no differences in adverse event rates for patients presenting with vs. without dissection (sICH: 0[percnt] vs. 8.2[percnt], p=0.61; mortality: 20.0[percnt] vs. 18.3[percnt], p=1.0). Notably, no AIS patients with dissection receiving aggressive therapy developed a sICH. There were also no differences in favorable outcome for patients presenting with vs. without dissection (discharge mRS ≤2: 26.7[percnt] vs. 20.4[percnt], p=0.52; 3 month mRS ≤2: 58.3[percnt] vs. 45.1[percnt], p=0.38). There were 3 deaths in patients with dissection: one death resulted from occlusion of a stent placed to treat stenosis caused by dissection.
CONCLUSIONS: Aggressive therapy, including intraarterial thrombolysis and endovascular treatment, appears to be as safe and effective when used in patients with ischemic stroke due to dissection as in AIS patients with other causes. It would be difficult to create an ethical randomized trial to evaluate aggressive therapy in this patient population. Disclosure: Dr. Jensen has nothing to disclose.

The ability to predict future epidemic threats, both in real and digital worlds, and to develop effective containment strategies heavily leans on the availability of reliable infection spreading models. The stochastic behavior of such processes makes them even more demanding to scrutinize over structured networks. This paper concerns the dynamics of a new susceptible-infected-susceptible (SIS) epidemic model incorporated with multistage infection (infection delay) and an infective medium (propagation vector) over complex networks. In particular, we investigate the critical epidemic thresholds and the infection spreading pattern using mean-field approximation (MFA) and results obtained through extensive numerical simulations. We further generalize the model for any arbitrary number of infective media to mimic existing scenarios in biological and social networks. Our analysis and simulation results reveal that the inclusion of multiple infective medium and multiple stages of infection significantly alleviates the epidemic threshold and, thus, accelerates the process of infection spreading in the population.


Sous-vide is a method of cooking food in vacuumed airtight plastic bags in a water bath or in a temperature-controlled steam environment for longer than normal cooking time. This paper,based on an explanation of this cooking technique,compares sous-vide with traditional heating approach through experiments. The findings suggest that meat quality is enhanced in the respects of color,fragrance,taste,shape and nutrition with the new cooking technique employed,which will provide reference for the innovation of traditional Sichuan dishes.


BACKGROUND
Genetic mechanisms contribute to blood pressure regulation. This study investigated whether glutathione peroxidase (GPx-3) tag single nucleotide polymorphisms (SNPs) are associated with hypertension in the rural areas of Fuxin county, Liaoning province, China.

METHODS
Indigenous Fuxin Han people participated, 523 unrelated hypertensives and 547 controls were recruited. All tag SNPs of GPx-3 gene were selected. We estimated SNP allele frequency in DNA pools with pyrosequencing.

RESULTS
Before Bonferroni correction, C allele frequency for rs8177417 was significantly higher in hypertensives than those in controls (23.4% vs. 19.3%, P = 0.014); T allele frequency for rs3828599 was significantly lower in hypertensives than those in controls (35.6% vs. 40.8%, P = 0.009). However, when a Bonferroni correction for multiple testing was applied, only the polymorphisms rs3828599 of GPx-3 gene was associated with hypertension (P = 0.045, OR: 0.833, 95%CI: 0.695 - 0.998).

CONCLUSION
The polymorphism of rs3828599 of GPx-3 gene might be associated with hypertension in rural Han Chinese from Fuxin, Liaoning.


One of the goals of the CBLAST Weak-Wind Experiment was to examine sea-surface fluxes in weak winds. The number of cases of fluxes for weak-wind conditions was reduced by frequent fog development shortly after the onset of weak winds. Fog leads to condensation on the transducers of the sonic anemometers and unreliable or flagged data. None the less, enough data was captured to identify basic characteristics of the turbulent flow for weak wind conditions. The weak-wind case is of considerable practical interest because it leads to poor dispersion and maintenance of high concentrations of contaminants in coastal zones. Weak winds can also lead to formation of dense fog over large areas, particularly with flow of warm air over cooler water. Weak-wind conditions over the sea often produce anomalous stress values due to interaction between the wind and wave field (e.g., Grachev et al., 2003). This paper concentrates on the influence of the nonstationarity of the wind field in weak-wind conditions. With weak large-scale flow, "background" mesoscale motions emerge as a dominant influence, leading to meandering of the wind vector and invalidation of the usual flux parameterizations. The background mesoscale motions may be due to inertial gravity waves or collapse of turbulence to twodimensional modes followed by vortex merging (upscale energy transfer). Other mechanisms include convection waves (e.g., Kuettner et al., 1987), solitons (Sun et al., 2004), inactive eddies (Högström et al., 1999), longitudinal vorticies aligned with the wind direction, or, simple waves in the horizontal wind field (Oettl et al., 2005). However, most of our time series reveal structures much more complex than expected from the above mechanisms, perhaps due to superposition of different modes. We also find that the mesoscale motions in the boundary layer are characterized by highly variable spectra (Vickers and Mahrt, 2007), not amenable to practical spectral similarity theory. In this study, we analyze turbulence data from the Air-Sea Interaction Tower (ASIT) collected during the CBLAST experiment in late summer of 2003, previously


A new spot-size converter (SSC) for coupling Si rib waveguides to 10-µm-mode-diameter single mode optical fibers was theoretically and experimentally evaluated. The core of the SSC consisted of a lateral and vertical Si inverse-taper having a rib-to-wire shape and a lateral silica normal-taper with a rib shape. The calculated coupling losses for an optimized structure were 0.65 and 0.66 dB for transverse-electric (TE) and transverse-magnetic (TM) polarizations, respectively. The losses of the fabricated SSCs were 2.7 dB (TE) and 3.0 dB (TM). The measured misalignment tolerance was ±1.2 µm for an extra-loss increase of 0.25 dB.


EXPLICIT SINGLE STEP TIME MARCHING DISCONTINUOUS GALERKIN METHOD WITH STAGE-DEPENDENT NUMERICAL FLUX PARAMETERS FOR A LINEAR HYPERBOLIC EQUATION IN ONE DIMENSION YUAN XU∗, CHI-WANG SHU† , AND QIANG ZHANG‡ Abstract. In this paper, we present the L2-norm stability analysis and error estimates for the explicit single-step time marching discontinuous Galerkin (DG) method with stage-dependent flux parameters, when solving a linear constant-coefficient hyperbolic equation in one dimension. Two well-known examples of this method include the Runge–Kutta DG method with the downwind treatment for the negative time marching coefficients, as well as the Lax–Wendroff DG method with arbitrary numerical flux parameters to deal with the auxiliary variables. The stability analysis framework is an extension and an application of the matrix transferring process based on the temporal differences of stage solutions, and a new concept, named as the averaged numerical flux parameter, is proposed to reveal the essential numerical viscosity in the fully discrete status. Distinguished from the traditional analysis, we have to present a novel way to obtain the optimal error estimate in both space and time. The main tool is a series of space-time approximation functions for a given spatial function, which preserve the local structure of the fully discrete schemes and the balance of exact evolution under the control of the partial differential equation. Finally some numerical experiments are given to validate the theoretical results proposed in this paper.


This study aims to examine perceived green human resource management (GHRM) influence on perceived in-role and extra-role green service behaviour. Specifically, drawing upon social identity theory, authors tested how green commitment mediates the relationship between GHRM and employees' green behaviour. The study employed cross-sectional research design in a non-contrived setting for data collection from 203 responses of banking sector employees in Afghanistan. Partial least squares structural equation modelling is applied by using SmartPLS 3 software. The empirical results confirmed that green commitment mediates the relationship between GHRM and employees' in-role and extra-role green service behaviour. This study explores green commitment as novel mechanisms through which GHRM practices influence employees' in-role and extra-role green behaviour in organisations.


Generally, the local full-waveform inversion (LFWI) is solved in a deterministic framework, in which a single solution is produced, without quantifying its uncertainties. We propose a multi-step strategy for uncertainty estimation in FWI and we demonstrate its applicability to the acoustic 2D Marmousi model. To cast the LFWI in a probabilistic framework, we use a genetic algorithm driven optimization, combined with a Markov chain Monte Carlo method (Gibbs sampler). The so derived posterior probability distribution (PPD) defines a possible set of starting models for subsequent LFWI which, in turn, transforms the initial set of starting models in a new set of final models exhibiting narrower PPDs and containing the true model.


In this paper, a novel GaN-based field stop-insulated gate bipolar transistor (FS-IGBT) is designed, which combines GaN-based Fin-MOS with the conventional material FS-IGBT, and the static and dynamic electrical characteristics of the device are simulated by Silvaco. The results show that the structure has a high saturation current (I on,sat) density of 155 kA cm−2 at 10 V gate voltage (V ge), an on-state voltage (V on) of 3.5 V, a breakdown voltage (BV) of 1650 V, and a switching speed of nanoseconds. The characteristics of the device are analyzed and compared with Fin-MOS. The results demonstrate that the vertical GaN-based device can display both high current density and high BV due to the FS layer that adjusts the electric field distribution in the N-drift region. The paper also analyzes the selection of device parameters and feasibility of device manufacturing based on the existing material growth method and device manufacturing technology.


The statistics of the ionisation response amplitude measured at selected points and their surroundings within sensitive regions of integrated circuits (ICs) under focused femtosecond laser irradiation is obtained for samples chosen from large batches of two types of ICs. A correlation between these data and the results of full-chip scanning is found for each type. The criteria for express validation of IC single-event effect (SEE) hardness based on ionisation response measurements at selected points are discussed.


This study contributes to discussions on the politics of (non-)deportability by focusing on the case of Afghans, the largest migrant community without a right to protection in Turkey, itself the country hosting the most refugees. This article examines how the politics of (non-)deportation is shaped and practiced for Afghans and the types of everyday strategies they employ to deal with deportability. We first argue that the politics of deportation in Turkey is predominantly shaped by the needs of the informal labour market, which accounts for one-third of the total labour force. Our findings suggest that forced labour and the hypermobility of Afghans is both tolerated and hidden by the state, while Afghans' fear of deportability operates as a disciplining apparatus. Second, we argue that, when spectacles of deportation are performed, three crucial factors help Afghans avoid deportation, namely their qawm-based (ethnic or kinship) background, the involvement of Afghan associations, and street-level negotiations with the authorities.


Formal models of voting have emphasized the mean voter theorem, namely, that all parties should rationally adopt identical positions at the electoral mean. The lack of evidence for this assertion is a paradox which this article attempts to resolve by considering an electoral model that includes 'valence' or non-policy judgements by voters of party leaders. In a polity such as Israel, based on proportional electoral rule, low-valence parties would adopt positions far from the centre, making coalition formation unstable. In Britain, by contrast, a party with a low-valence leader would be subject to the demands of non-centrist activists.


The cellular method ®, developed by the author, utilizes an innovative approach to determine the optimal shading form for a given period that would yield maximum energy efficiency. The method examines numerous cells, located on a proposed exterior shading plane, for their periodic shading necessity. The overall periodic shading necessity of all cells reveals an optimal shading necessity pattern which in turn provides maximum energy ■ d conservation in mechanical systems while thermal and visual comfort are maintained. In addition, by examining different shading planes for a given period, the method can provide an optimal three-dimensional shading necessity pattern. In contrast to previous methods of defining shading form, where moderate calculations are often utilized, this method takes advantage of the capabilities of today's computers. By extensive hourly examinations of numerous cells, considering different parameters determined by the user, the method provides much finer resolution of shading necessity patterns. Such patterns indicate more accurate shading forms which can optimize building energy conservation. CHAPTER


Current investments by the international HIV/AIDS sector to expand health services offer unprecedented opportunities to reinforce health care infrastructures. Strengthened reproductive health services and contraceptive services in particular are imperative since their benefits are highly complementary to and synergistic with HIV/AIDS control objectives. Evidence is accumulating that contraception is a potentially powerful and cost-effective HIV prevention strategy enabling HIV-infected women to prevent undesired pregnancies thereby averting mother-to-child HIV transmission. One strategy for extending the benefits of contraceptive services to people affected by HIV is to integrate these services into HIV/AIDS services. Contraceptive services are integral components of HIV services as opposed to mere complements since they lead to the same outcome namely a decrease in HIV infections. For both individuals who are HIV infected and those who are not contraception offers a variety of established benefits to the mother her family and her community. (excerpt)


There are many positioning systems available today. The most prominent of these sys-tems is the Inertial Navigation System, which is increasingly preferred because it works with its own internal system independent of external stimuli. This system detects posi-tion, orientation and velocity information by means of accelerometer and gyroscope sensors. Using this information, it is possible to make predictions for the next position, orientation and speed with various algorithms.
In the studies conducted so far, Kalman Filter algorithms have been predomi-nantly used for prediction. In this study, Long Term-Short Memory (LSTM) neural network architecture, Bidirectional Long Short-Term Memory (BLSTM), Gated Recur-rent Unit and Kalman Filtering methods, which are among the deep learning algorithms that have proven themselves as prediction algorithms, are examined in detail and a comparative study is presented.
Considering the findings obtained in the simulation studies detailed in the thesis, it is revealed that Gated Recurrent Unit GRU estimation algorithm shows the best perfor-mance with an RMSE value of 2.5414. LSTM, BLSTM methods achieved an RMSE val-ue of 2.5547, 2.7592 respectively. In the studies conducted through Kalman filter, one of the traditional estimation methods, an RMSE value of 2.9322 was obtained.


success by what it does for the rhetor rather than the victim. In contrast, Lazare identifies these eight tactics of self-defense as inherent failures to rhetorically heal the victim or the relationship. He also makes an insightful distinction between guilt and shame: while guilt for wrongdoing is individual, shame can be collective (just like pride in one's group or nation). On these grounds, Lazare argues that representative apologies for group offenses in past generations can be justified as a means of removing corporate shame. In sum, On Apology is a substantial contribution to the subject; it offers important complements and correctives to the existing rhetorical literature on apology and could be generative of new lines of investigation. Those who study public apologies and reconciliation would do well to let this work inform their theorizing and analysis.


In this paper, we provide a sufficient condition for the absolute convergence of multiple Fourier series of a function of φ (cid:2) Λ 1 , . . . , Λ N (cid:3) -bounded variation. This condition generalizes one for a single Fourier series proved by Schramm and Waterman. We apply the classical technique of summation by parts and some key inequalities for convex functions (including the Jensen's inequality) and Δ 2 -functions to prove our main result.


OBJECTIVE
To determine the benefit of nasally inhaled dornase alfa in patients with cystic fibrosis and nasal symptoms.

DESIGN
Double-blind placebo-controlled trial.

SETTING
Cystic Fibrosis Regional Center of Campania at the University of Naples "Federico II."

PATIENTS
A total of 24 patients with cystic fibrosis and chronic sinusitis.

INTERVENTIONS
Patients underwent sinonasal surgery during a 3-year period and received once-daily doses of either dornase alfa (2.5 mg) or hypotonic saline solution (5 mL) beginning 1 month after surgery and for a 12-month period.

MAIN OUTCOME MEASURES
Primary outcomes were nasal-related symptoms and nasal endoscopic appearance; secondary outcomes were forced expiratory volume in 1 second, nasal computed tomography findings, and saccharine clearance test results. Patients were evaluated before and after treatment.

RESULTS
After surgery, all outcomes were significantly improved for each treatment at 1 month (P<.05); primary outcomes were improved at 24 and 48 weeks in the group receiving dornase alfa (P<.05), and at 12 weeks in the group receiving placebo. Secondary outcomes were better in the dornase alfa group (P<.01) than in the placebo group at 12 months except for the saccharine clearance test results. In particular, median relative difference in forced expiratory volume in 1 second between dornase alfa and placebo was significantly improved in the dornase alfa group (P<.01).

CONCLUSIONS
Nasally inhaled dornase alfa can be effective in patients with cystic fibrosis and sinonasal disease who do not respond to conventional therapy after surgical treatment. Further studies should be carried out to determine the long-term effect on sinus disease, recurrence of polyps, and quality of life.

Background. Burnout is a common psychological syndrome among nurses, especially in the first few years of working. However, limited studies have evaluated the factors related to burnout among junior nurses. Aims. To investigate the levels of psychological flexibility, stress, and burnout among junior nurses and examine the role of demographic and workplace relationship factors, psychological flexibility, and perceived stress on burnout among junior nurses. Materials and Methods. A convenience sample of 481 junior nurses was recruited from three tertiary hospitals in China from July 2021 to August 2022. Data were collected, including demographic data, workplace relationships, psychological flexibility (measured by experiential avoidance and cognitive fusion), perceived stress, and burnout. The Independent t-test, one-way ANOVA, Wilcoxon–Mann–Whitney test, Kruskal–Wallis test, Spearman correlation, and hierarchical regression were used to analyze the data. Results. Junior nurses had a high level of burnout in different dimensions. Nurses with an undergraduate education, nurses working in the first year, and a lack of support from supervisors and poor colleague (nurse-nurse and nurse-doctor) relationships had the lowest level of psychological flexibility and the highest level of perceived stress and burnout. Spearman correlation indicated that experiential avoidance, cognitive fusion, perceived stress, and burnout were positively associated with each other. The regression model showed that psychological flexibility (especially cognitive fusion) and perceived stress influenced burnout in junior nurses. Conclusions. Higher psychological flexibility and lower perceived stress appear to improve burnout in junior nurses. Therefore, interventions targeting these two factors may provide a viable direction for the reduction of burnout among junior nurses. Implications for Nursing Management. Hospital authorities should create a harmonious working environment and provide some psychology training programs for junior nurses.


In today's world, we came to know large number of techniques like navigation systems and warning alarm systems that assist driver and make driving an easy job. Traffic accidents due to human errors cause many deaths and injuries around the world. Drowsiness and sleeping while driving are now identified as one of the reasons behind fatal crashes and highway accidents caused by drivers. There are some techniques already available in the market. It is a necessary step to come with an efficient technique to detect drowsiness as soon as driver feels sleepy. This could save large number of accidents. This research provides efficient technique for detecting driver's drowsiness. After acquiring image, focus has been made on eyes of driver using Viola-jones eye tracking method, after face detection. Edges have been extracted from the eyes detected. Using Hough transformation, iris has been extracted and then the states of the eyes used to detect drowsiness of driver. Experiments have been done on large number of drivers. Comparison of results with existing systems show that the implemented method gives desired output and it is better than existing systems.


A novel DOIND logic approach is proposed for domino logic, which reduces the leakage current with a minimum delay penalty. Simulation is performed at 70 nm technology node with supply voltage 1V for domino logic and DOIND logic based AND, OR, XOR and Half Adder circuits using the tanner EDA tool. Simulation results show that the proposed DOIND approach decreases the average leakage current by 68.83%, 66.6%, 77.86% and 74.34% for 2 input AND, OR, XOR and Half Adder respectively. The proposed approach also has 47.76% improvement in PDAP for the buffer circuit as compared to domino logic.


The focal point of this research was to establish the liquidity-viability link in quoted non-financial firms in Nigeria. Liquidity improves the profitability of firms but not its solvency. The solvency and performance of a firm exclusively anchor on the firm's capacity to realize the "twin conflicting" targets of liquidity sufficiency and stable growth through a diversified and stable asset-liability mix. The firm's inability to strike an equilibrium balance among meeting financial obligations, sufficient liquidity and profitability has led to insolvency of most firms in Nigeria. Most empirical studies in Nigeria ignore effect of cash flow management on the non-financial sector to focus on the financial sector. Use the regression model predominantly and also ignore the widely accepted econometric process of a pre and post diagnostic test. This study focuses on 13 quoted non-financial sectors in Nigeria firms from 1999-2020. The preliminary test was conducted to determine the best fit model. Liquidity proxy by the current ratio significantly influences ROE and non-significantly on ROE when proxy by the cash flow ratio. Findings also divulged a bidirectional nexus between current ratio, cash flow ratio, and ROE and a non-causal nexus with other variables. Policy recommendations are further discussed.


We report Nernst effect measurements for some crystalline films of Ca and Zn-doped yttrium barium copper oxide grown by pulsed laser deposition. We argue that our results and most of the published data for LSCO are consistent with the theory of Gaussian superconducting fluctuations.


In this paper, a novel single-stage valve system activated by a piezostack actuator is proposed and experimentally evaluated at both room temperature (20 °C) and high temperature (100 °C) conditions. A hinge-lever displacement amplifier is adopted in the valve system to magnify the displacement generated from the piezostack actuator. After explaining the operating principle of the proposed piezostack-driven single-stage valve system, the geometric dimensions and mechanical properties of the valve components are discussed in details. An experimental apparatus is then manufactured to evaluate the performances of the valve system such as flow rate. The experimental apparatus consists of a heat chamber, which can regulate the temperature of the valve system and oil, pneumatic-hydraulic cylinders, a hydraulic circuit, a pneumatic circuit, electronic devices, an interface card, and a high voltage amplifier. The pneumatic-hydraulic cylinder transforms the pneumatic pressure into hydraulic pressure. The performances of the valve system regarding spool response, pressure drop, and flow rate are evaluated and presented. In addition, the performance of the valve system under high temperature condition is compared with that under room temperature condition. The experimental results are plotted in both frequency and time domains.


Arrhythmogenic right ventricular dysplasia-cardiomyopathy (ARVD-C) is a rare heart condition with characteristic thinning and fibroadipose tissue replacement of the myocardium of the right ventricular wall. We have seen 20 autopsy cases with morphologic features fitting the criteria of ARVD-C in our hospital in the past 5 years. The clinical characteristics of these patients were not those described in the literatures. Two of the 20 patients died suddenly without obvious cause, and only one of the 20 patients fit the classic clinical and morphologic description of the disease. The remaining patients were chronically ill with significant comorbidities, and the pre-mortem diagnosis of ARVD-C was not suspected in all these patients. We suspect that ARVD-C could be a spectrum of morphologic changes with variable clinical manifestations, and it may be far more common than that reported in the literature. The spectrum of the morphologic changes of the right ventricular wall raise questions of the diagnostic criteria at the time of autopsy and request for more clinical pathologic correlation. Alternatively, these morphologic features may represent a specific dilated right ventricular cardiomyopathy distinct from the classic description of arrhythmogenic right ventricular dysplasia/cardiomyopathy with genetic component.

I have just completed my adult nurse training, but I am unable to find any employment with the local primary care trust (PCT), nursing homes, health centres or even on the bank. This is, in part, because of the huge deficits my local PCT has built up (news October 25). Three years of my time and money have been wasted. I am now looking for work outside nursing. The government needs to acknowledge the situation facing so many newly qualified nurses. I am saddened by having to make these difficult decisions but I must ensure some quality of life for my family and me.


Even though Finland has proportional elections, single-party control in Finnish local councils is not uncommon contrary to what one might expect. The largest party holds more than half of the seats in every third Finnish local council and is thus likely to govern alone. This study investigates whether single-party and coalition governed municipalities differ in their economic outcomes. Common pool models predict that when there is a governing coalition, all the parties aim to target some spending at their core constituents, while costs are shared equally across all parties. This would mean that coalition governments result in higher spending. Using data from 445 Finnish municipalities for the years 1980–2010, I provide causal evidence that is consistent with the predictions of common pool models. Estimates suggest that single-party control decreases total expenditures and revenues by around 200–300 euros per capita. I also analyze the effect in several areas of spending and revenues, but do not find any clear results. I exploit close elections as a source of exogenous variation using a regression discontinuity design (RDD) approach tailored for proportional elections.


ABSTRACT Herman Moll's The World Described (1720), the pre-eminent folio atlas of Hanoverian Britain, departs from the usual Ortelian model in the selection and ordering of its contents. It placed Britain at the centre of the atlas so that the first half provided a cartographic description of Britain's overseas commercial interests, while the second half showed the kingdom's political interests on the Continent. The argument presented here is that Moll gave priority to global rather than imperial dimensions in helping his British readers appreciate the multifarious geography of their country's interests.


To examine whether the fidelity of DNA synthesis is reduced in tumor cells, M13 mp2-based fidelity assays were carried out using 15 samples of whole-cell extracts from primary mouse thymic lymphomas induced by alkylating agents. We found that DNA synthesis activities of thymic lymphomas, detected as incorporation of [3H]TTP into acid-insoluble materials, were 2to 10-fold higher compared to those of normal thymus. Furthermore, mutant frequencies in the forward mutation assay of DNA synthesis were increased 2to 7-fold in cell extracts from thymic lympho mas compared to those from normal thymus. As the DNA polymerase /! (pol ß) activity was extremely high in the thymic lymphomas, we screened mutations in the pol ßgene to examine the possibility of involvement of mutated pol ßin reduction of the fidelity of DNA synthesis. Of 20 lymphomas, one case of point mutation (T to A) was found by reverse transcription-PCR single-strand conformation polymorphism analysis. These results suggest that the mutagenic DNA synthesis is involved in murine thymic lymphoma genesis, although mutation of the pol ßgene is not a major causal event.


PURPOSE: A method for transmitting an MAC(Medium Access Control) PDU(Protocol Data Unit) allocating an uplink radio resource to a terminal is provided to quickly prevent a problem of a call by preferentially performing the data transmission of the CCCH(Common Control Channel). CONSTITUTION: Resources are allocated about data canning be transmitted in a common control channel. If the electrical transmission of a buffer status information is necessary, the resources about the buffer status information transmission is allocated(S130). If the data is transmitted in a logical channel except the common control channel, the resources about data is allocated(S140). The transmitted MAC PDU is in the logical channel(S150).


Curbs are one of the essential elements of urban and highway traffic environments. Robust curb detection provides road structure information for motion planning in an autonomous driving system. Commonly, video cameras and 3D LiDARs are mounted on autonomous vehicles for curb detection. However, camera-based methods suffer from challenging illumination conditions. During the long period of time before wide application of Deep Neural Network (DNN) with point clouds, LiDAR-based curb detection methods are based on hand-crafted features, which suffer from poor detection in some complex scenes. Recently, DNN-based dynamic object detection using LiDAR data has become prevalent, while few works pay attention to curb detection with a DNN approach due to lack of labeled data. A dataset with curb annotations or an efficient curb labeling approach, hence, is of high demand. In this paper, we present how to build a curb dataset with LiDAR data for autonomous driving highly automatically. Firstly, a Semantic High Definition map (SHD map) in a global coordinate frame is generated by applying both SLAM and semantic segmentation on consecutive LiDAR frames. Next, a Road HD map (RHD map) is generated from the SHD map by removing its dynamic noise caused by road users e.g. cars. After that, a Curb Instance map (CI map) can be obtained from the filtered RHD map by a series of curb point extraction and growing. Finally, the CI map can be projected back to single frames for direct, highly automatic curb labeling. In order to validate our proposed labeling method, on top of an open public LiDAR semantic dataset SemanticKITTI [1], an additional curb dataset is built. We run both semantic segmentation and instance segmentation methods on this built dataset. Experimental results show that the curb annotations have good consistency and accuracy. We released this dataset and it is publicly available at https://download.mindspore.cn.


In order to better conform to the development of the times, our country urgently needs to cultivate a comprehensive quality of independent thinking, team cooperation and practical ability. However, this requirement is obviously not achieved through the traditional teaching model. In order to achieve the desired results of teaching, various schools have launched a project. In view of this, the author focuses on the teaching of physical education in Higher Vocational colleges, and makes a more in-depth discussion on the feasibility and problems of implementing project-based teaching.

A test particle trajectory approach is developed for the simulation of deep bed filtration. A 3-D network of constricted pores represents the pore space of granular filters, network-scale trajectories of a large number of non-Brownian test particles are computed, and filter coefficient predictions are obtained for horizontal, down-and upflow filtration operation. This simulator yields numerical results that agree excellently with our earlier predictions by the pore-scale trajectory-based population balance method. The new approach, however, circumvents the cumbersome step of calculating the impacted fraction in each unit cell, which the earlier method required, by providing direct statistical estimates of the local and overall deposition rates for continuous and discrete pore-size distributions. For large superficial velocities (Vs > ∼1 mm/s) and distributed pore size, downflow filters are more efficient than horizontal flow filters, whereas for small velocities (Vs< ∼ 0.5 mm/s) the opposite is observed. Horizontal flow operation is also favored by uniform packing for almost any value of the external pressure gradient. Upflow operation is the least efficient for the packings considered here over a broad range of superficial velocity and particle-size values. Observed differences among the three filtration types are maximal for uniform packings and decrease considerably with increasing packing heterogeneity.


3 Abstract: This review gives an insight into the recent advancements in biotechnology with respect to its application in the environment. Particular emphasis is on food production, pollution control and bioenergy production. Environmental biotechnology combines molecular biology and cell manipulation in order to produce valuable products with a lot of new, effective and acceptable properties. Global food security (good quality food, disease resistant varieties of cereal crops), use of genetic engineering to minimize pollution and plants as a source of energy, are possible by the careful use of biotechnological techniques. In the coming future biotechnology will become major driving force in the field of environment, beneficial both for underdeveloped and developed countries.


It is widely acknowledged that Joseph Papp started colorblind casting in the United States in a sustained and visible way. In addition, he utilized uni-racial casting at various times in the history of the New York Shakespeare Festival (NYSF). Based on the general agreement that Papp's casting had a significant impact on the American theatre, it is clear that his work functioned as a racial project from the perspective of racial formations. Despite the fact that Papp's work has had an impact as a racial project in the United States, there are significant elements to his casting which have yet to be explored. The purpose of this dissertation is to analyze the extent and nature of colorblind and uniracial casting at the NYSF and explore how the two different methods of non-traditional casting were used at various times in the organization's history.


By KenNETH W. Millican, B.A., Cantab., M.R. C.S., London: H. K. Lewis, 1883, pp. 107. This essay is a bold application of the Darwinian hypothesis to explain certain anomalous forms and combinations of disease and disputed points relating to the specificity of disease. The general idea is not altogether a novel one, but Mr. Millican develops it more fully than has yet been done, and attempts to show how very rapidly a transition from one specific form to another might take place owing to the extreme rapidity with which one generation of bacteria is replaced by another. The author is necessarily a thorough-going germist, unreservedly attributing active pathogenic properties to the

Five isotopes of mendelevium, with mass numbers 248 through 252, were studied by means of $\ensuremath{\alpha}$-particle spectroscopy. The isotopes were produced by bombarding $^{241}\mathrm{Am}$ and $^{243}\mathrm{Am}$ targets with $^{12}\mathrm{C}$ and $^{13}\mathrm{C}$ ions accelerated by the Berkeley heavy-ion linear accelerator. The half-lives of the nuclides and the energies of the main $\ensuremath{\alpha}$-particle groups, respectively, were observed to be: $^{248}\mathrm{Md}$: 7 \ifmmode\pm\else\textpm\fi{} 3 sec, 8.32 \ifmmode\pm\else\textpm\fi{} 0.02 MeV; $^{249}\mathrm{Md}$: 24 \ifmmode\pm\else\textpm\fi{} 4 sec, 8.03 \ifmmode\pm\else\textpm\fi{} 0.02 MeV; $^{250}\mathrm{Md}$: 52 \ifmmode\pm\else\textpm\fi{} 6 sec, 7.75 \ifmmode\pm\else\textpm\fi{} 0.02 MeV; $^{251}\mathrm{Md}$: 4.0 \ifmmode\pm\else\textpm\fi{} 0.5 min, 7.55 \ifmmode\pm\else\textpm\fi{} 0.02 MeV; $^{252}\mathrm{Md}$: 2.3 \ifmmode\pm\else\textpm\fi{} 0.8 min, no $\ensuremath{\alpha}$ decay. The $\ensuremath{\alpha}$-particle energies of $^{245}\mathrm{Es}$, $^{246}\mathrm{Es}$, and $^{247}\mathrm{Es}$, produced mainly by ($\mathrm{HI},\ensuremath{\alpha}\mathrm{xn}$) reactions, were measured to be 7.73 \ifmmode\pm\else\textpm\fi{} 0.02, 7.36 \ifmmode\pm\else\textpm\fi{} 0.03, and 7.31 \ifmmode\pm\else\textpm\fi{} 0.03 MeV, respectively, and the half-life of $^{247}\mathrm{Es}$ was found to be 4.7\ifmmode\pm\else\textpm\fi{}0.3 min. Excitation curves for producing the Md isotopes and some other activities are presented. Estimates for the electron-capture branching of the Md isotopes are given. $\ensuremath{\alpha}$-decay hindrance factors were calculated using the spin-independent equations of Preston. The $\ensuremath{\alpha}$-decay energy systematics of the mendelevium isotopes is discussed.

EDITOR,—The proposed two stage NHS complaints procedure1 already, in effect, operates for complaints in general practice. Many practices have in house, informal procedures, and many family health services authorities have informal conciliatory procedures. These broadly equate with stage I of the proposed procedure.14 The proposed stage II or panel review equates with the current formal, service committee procedure. Thus not only have Professor Alan Wilson and his colleagues …


In this paper, a new tomographic scan method with fixed installed detectors and rotating source from gamma projector was presented to diagnose the industrial plants which were impossible to be examined by conventional tomographic systems. Weight matrix calculation method which was suitable for volumetric detector and statistical iterative reconstruction method were applied for reconstructing the simulation and experimental data. Monte Carlo simulations had been performed for two kinds of phantoms. Lab scale experiment with a same condition as one of phantoms, had been carried out. Simulation results showed that reconstruction from photopeak counting measurement gave the better results than from the gross counting measurement although photopeak counting measurement had large statistical errors. Experimental data showed the similar result as Monte Carlo simulation. Those results appeared to be promising for industrial tomographic applications, especially for petrochemical industries.


Tagging is a globally relevant occupation typically engaged in by adolescents, particularly those likely to come into contact with social and healthcare services (Fuhrer, 2004). This discussion aims to enhance understanding of tagging through a synthesis of international literature from a range of disciplines, which identifies and critically evaluates the impact of cogent social, political, economic, cultural and historical factors influencing tagging. These factors are considered in terms of tagging's form, function and meaning. From the perspective of contemporary society, the form of tagging and its functions as a voice against oppression, gang related tagging and tagging as part of hip hop culture are considered. Meanings encompass motivating aspects of fame, belonging, risk taking and status. Tagging's implications for health and well‐being are considered. It's perceived image as a deviant occupation is acknowledged and explored, while credit for its health promoting qualities, such as developing and earning respect, loyalty and problem solving are also noted.


Ischaemic heart disease is a common cause of death and disability globally. Myocardial revascularisation is one of the most important components of the complex therapy of atherosclerosis. Clopidogrel has long been an attractive antiplatelet drug in clinical practice. Large amounts of evidence and data for P2Y12 platelet inhibitors support the use of clopidogrel in various clinical situations.The pharmacokinetic and pharmacodynamic features of the drug should be considered in everyday practice. Current guidelines clearly define the place and role of clopidogrel in the treatment of patients before and after revascularisation. This article focuses on various aspects of antiplatelet therapy, considering the patient-related risks, based on the European guidelines for the treatment of patients with acute and chronic coronary syndrome.Received 21 September 2021.

In the new rural development framework, the supply of public goods in rural areas is a huge systematic project, which needs aspects of reform and adjustment. At present, the supply of public goods in rural areas faces many difficulties. It is particularly important to establish an effective public decision-making allocation mechanism, improve the irrational supply structure and adjust the supply of the induced pattern of supply and compulsory. This paper, the entropy point of view, based on minimum entropy principle, through self-organization functions and the external environment of supply system, according to positive entropy flow or negative entropy flow supply system, resulting in both the mandatory supply system and the induced supply system can not effectively prevent the system entropy increase. The most effective way is to make the mandatory supply system and the induced supply system fully integrated, complementary advantages, so as to gradually evaluate the supply efficiency of rural public goods.


The domain of artificial intelligence (AI) is wide. Originally AI was defined as the discipline of computers that show intelligent human behavior. Now AI also refers to computer systems that show complex behavior similar to living systems like swarms, ant colonies, microbiology, and neural systems. There is a distinction between "'strong" AI—computer functions that really have strong similarities with intelligent human reasoning and show some kind of self awareness—and "weak" AI—computer applications that deal with limited application areas and contain some practical knowledge and seem to have some intelligent features, such as expert systems and heuristic search algorithms. The focus of engineering applications of AI such as the ones considered in this circular is more on weak AI. However, it should be noted that the boundaries between strong and weak AI are not sharp and often AI systems move from one type to the other. A general distinction between "ordinary" computer systems and AI is the complexity of the AI computer systems.


I believe there are a few technical points presented in this paper that should be clarified. The method of operation of these units, when solid waste is charged, is critical in both the production of energy and the affect of the effluent gases on the boiler tubes. After subjection to a starved air atmosphere in the primary chamber, the effluent gases entering the secondary chamber (or afterburner) definitely have an appreciable amount of particulate carry over. The efficient and automatic action of the excess air condition and retention time in the secondary is essential to burn off these particulates and produce a clean exit gas (below 0.08 grains of particulate per standard cubic foot of dry flue gas) so that APC equipment will not be required and boiler tube corrosion can be controlled. There are minimum charging rates at present, below which energy production does not appear practical. This should always be considered on an hourly basis, not daily. A Hofmann rule of thumb for an individual waste heat exchanger (or boiler) is 1500 lb/hr minimum feed of waste to the primary, under the current state of the art. Further, for energy production, heavy "batch" feeding is impractical. Hofmann rule number two is that, due to the dynamics of volatile release in solid wastes, feeding should be continuous while energy is being produced, either by ram charges or by conveyance automatically. Ram charging may be termed a form of "batch" feeding, but the maximum 1977


The sources of ultra-high-energy cosmic rays are still unknown, but assuming standard physics, they are expected to lie within a few hundred megaparsecs from us. Indeed, over cosmological distances cosmic rays lose energy to interactions with background photons, at a rate depending on their mass number and energy and properties of photonuclear interactions and photon backgrounds. The universe is not homogeneous at such scales, hence the distribution of the arrival directions of cosmic rays is expected to reflect the inhomogeneities in the distribution of galaxies; the shorter the energy loss lengths, the stronger the expected anisotropies. Galactic and intergalactic magnetic fields can blur and distort the picture, but the magnitudes of the largest-scale anisotropies, namely the dipole and quadrupole moments, are the most robust to their effects. Measuring them with no bias regardless of any higher-order multipoles is not possible except with full-sky coverage. In this work, we achieve


The aim of our study is to compare two a priori different approaches: bilinearity and cyclostationarity. Indeed, we underline that cyclostationary and bilinear tools make it possible to determine both nonlinear and nonstationary links. These results are based on calculations, simulations for synthetic signals and finally applications to industrial signals. Then, we introduce different applications of these approaches to industrial vibrations. These methods enable us to obtain much more interesting results than classical methods such as Fourier, spectrum, time-frequency studies etc. Finally we conclude on the interest and the reliability of such approaches and we introduce a method to determine if a link between two frequencies is rather cyclostationary than bilinear. This method is based on the use of higher-order cyclic statistics.

Aim: to compare hemostatic parameters obtained by di erent methods in patients with primary hip joint replacement and with post- operative antithrombotic prophylaxis using dabigatran etexilate.
Materials and methods. We examined 27 patients (17 women and 11 men) with coxarthrosis (stage III) after primary hip joint replace- ment. For prophylaxis of thromboembolic complications all patients received dabigatran etexilate, the duration of prophylaxis was 35 days. We assessed hemostasis state before, on the first and fifth days after surgery using clotting tests, thromboelastography and thrombodynamics (TD).
Results. Results show the relationship of spontaneous clots in TD test with signs of high clotting activity. Comparative evaluation of hemostatic parameters in plasma and in whole blood showed that 1) standard coagulation tests reflect only isolated hemostasis changes and 2) the appearance of spontaneous clots in TD test are likely to indicate a hypercoagulability and to be the basis to stratify patients according to hypercoagulation risk. Fixed doses of dabigatran etexilate did not provide proof prevention in patients undergoing total joint hip replacement.
Conclusion. This study can be seems a starting point to personalize the dabigatran feetexilate dosing in such patients with initially high coagulation potential.

The result in this research was indicated that there was improvement of the students' reading comprehension. it was indicated by the students' mean score of post-test (3,40) was greater than pre-test (2,02). Even, for the level significant (p) 5% and df = 21, and the value of table is 1,721, while the value of t-test is 16,13. it means that, the t-test value is greater than t-table (16,13 ≥ 1,721). Thus, it can be concluded that the students' reading comprehension is significant better after getting the treatment. So, the null hypothesis (H0) is rejected and the alternative hypothesis (Ha) is accepted.


This article examines a century of policing in Eugene, Oregon, from 1862 to 1932. Its central argument is that the city's early civic leaders and law enforcement officers were concerned with preserving the status quo and image of the city by restricting the entrance of the "dangerous class." As the city expanded, however, and the police department grew to meet the demands of the changing city, the department increasingly suffered the same problems it had been designed to stop. Although the department's ability to successfully address crime and the city's targeted concerns fluctuated over time, the problems within the force remained. Eugene's law enforcement history, as a result, both substantiates the larger patterns in American law enforcement history and deviates from that pattern in unique ways

Silicon nanoscrews with aspect ratio of 3, 6 and 9 corresponding to 4, 8 and 12 etching cycles are fabricated by CsCl self-assembly lithography and inductively coupled plasma (ICP) dry etching with "Bosch Process", which can reduce the reflection to below to 10% for wavelength from 400 to 1000 nm. A layer of Cadmium sulfide (CdS) film covers onto the silicon nanoscrews surface to photoresistor. The XRD pattern shows the CdS packed both on the nanoscrew and planar surface are well-crystallized. The nanoscrew substrate with the large surface ratio can increase the light absorption and quantity of sensitive material, which can improve the photosensitivity of the CdS photoresistor compared to the planar one obviously. However, the aspect ratio of nanoscrew is not the larger the better for that the high aspect ratio also increases the difficulty of CdS package. The photosensitivity response test results show that the nanoscrew photoresistor with 6 aspect ratio has the best performance under different illumination. With 10000 μW/cm2, the best photosensitivity response achieves to 141 for nanoscrew sample.

Inflationary models including vector fields have attracted a great deal of attention over the past decade. Such an interest owes to the fact that they might contribute to, or even be fully responsible for, the curvature perturbation imprinted in the cosmic microwave background. However, the necessary breaking of the vector fields conformal invariance during inflation is not without problems. In recent years, it has been realized that a number of instabilities endangering the consistency of the theory arise when the conformal invariance is broken by means of a non-minimal coupling to gravity. In this paper, we consider a massive vector field non-minimally coupled to gravity through the Gauss-Bonnet invariant, and investigate whether the vector can play the role of a curvaton while evading the emergence of instabilities and preserves the large-scale isotropy.


This paper is motivated by a recent result of Wolf \cite{wolf} on the minimum number of monochromatic 4-term arithmetic progressions(4-APs, for short) in $\Z_p$, where $p$ is a prime number. Wolf proved that there is a 2-coloring of $\Z_p$ with 0.000386% fewer monochromatic 4-APs than random 2-colorings; the proof is probabilistic and non-constructive. In this paper, we present an explicit and simple construction of a 2-coloring with 9.3% fewer monochromatic 4-APs than random 2-colorings. This problem leads us to consider the minimum number of monochromatic 4-APs in $\Z_n$ for general $n$. We obtain both lower bound and upper bound on the minimum number of monochromatic 4-APs in all 2-colorings of $\Z_n$. Wolf proved that any 2-coloring of $\Z_p$ has at least $(1/16+o(1))p^2$ monochromatic 4-APs. We improve this lower bound into $(7/96+o(1))p^2$.
Our results on $\Z_n$ naturally apply to the similar problem on $[n]$ (i.e., $\{1,2,..., n\}$). In 2008, Parillo, Robertson, and Saracino \cite{prs} constructed a 2-coloring of $[n]$ with 14.6% fewer monochromatic 3-APs than random 2-colorings. In 2010, Butler, Costello, and Graham \cite{BCG} extended their methods and used an extensive computer search to construct a 2-coloring of $[n]$ with 17.35% fewer monochromatic 4-APs (and 26.8% fewer monochromatic 5-APs) than random 2-colorings. Our construction gives a 2-coloring of $[n]$ with 33.33% fewer monochromatic 4-APs (and 57.89% fewer monochromatic 5-APs) than random 2-colorings.

Random Early Drop (RED) is widely applied in Mobile Ad-hoc NETworks (MANETs) for congestion control. It randomly drops packets to prevent congestion from occurring, while keeping proper queue size of Route Request (RREQ) packets at the same time. Unfortunately, in the case of severe congestion and large amounts of RREQ packets in the queue, RED algorithm with tune parameters is not able to improve the congestion status properly. This paper proposes a Dynamic RED (DRED) mechanism based on the fitting curve of packet delivery ratio and packet sending rate, which can be readily achieved in practice. DRED presupposes threshold value for initiating and dynamically changes it according to the function regression. Compared to First In First Out (FIFO) and RED with tune parameters mechanisms, simulation results show that DRED has better performance in terms of average end-to-end delay, Hello packet overhead and packet delivery ratio, while avoiding obvious increase of routing discovery frequency.


police to the community and ultimately restoring social order, normalizing the police and crime control. A diversionary tactics model tested in one locality was later applied as a national model. As Bowden trenchantly observes, the youth projects became purveyors of symbolic power for the police (p. 135). However, it is noteworthy that the exercise of power is not necessarily hegemonic. An example is given of one project (Pineview) which stood its ground and resisted the power and domination of the pervasive model. Bowden's rich ethnographic mining of a substantial data set gives us insights into the lives of young people in a disadvantaged community at the height of the Celtic Tiger. Bowden's ''Plumford Boys'' are poignantly reminiscent of Chambliss's ''Roughnecks,'' whose own consequential run-ins with authority figures were chronicled more than forty years earlier. Defeat in a football match with the Garda Sı́ochána results in the presentation of medals to the losers as well as the winners. But as Bowden observes, this is a classic example of symbolic violence at work. The gift exchange itself delivers a message of physical and institutional superiority: ''the pedagogical communication facilitated the classification or stratification of winners and losers, thus defining the social place of both'' (p. 159). This is a great read. It offers a rare insight into the strategizing of the modern bureaucratic state as it extends its remit and seeks to legitimize itself in the eyes of the citizenry. It demonstrates the craft of sociology at its best: theoretically informed analysis which asks some very hard questions about power, domination, and the institutionalization of exclusion. This book would be of considerable interest to those engaged in sociology, public policy, crime, and the law.


An unusual feature of the 2004-6 eruptive activity of Mount St. Helens has been the continuous growth of successive spines that are mantled by thick fault gouge. Fault gouge formation requires, first, solidification of ascending magma within the conduit, then brittle fragmentation and cataclastic flow. We document these processes through field relations, hand samples, and thin-section textures. Field observations show that the gouge zone is typically 1-3 m thick and that it includes cataclasite and, locally, breccia in addition to unconsolidated (true) gouge. The gouge contains multiple slickenside sets oriented subparallel to each other and to the striation direction, as well as surface striations parallel to extrusion direction. Hand specimens show the cataclasite and gouge to be composed of a wide size range of broken dome and wall-rock fragments. This grain-size heterogeneity is even more pronounced in thin section, where individual samples contain fragments that span more than four orders of magnitude in size (from more than 10 to less than 10 -3 mm). Textures preserved within the gouge zone provide evidence of different processes operating in time and space. Most individual fragments are holocrystalline, suggesting that crystallization of the ascending magma preceded gouge formation. Cataclasite samples preserve a wide range of clast sizes; pronounced rounding of many clasts indicates extensive abrasion during transport. Within the gouge, crystals and lava fragments adjacent to finely comminuted shear zones (slickensides) are shattered into small, angular fragments that are either preserved in place, with little disruption, or incorporated into shear trains, creating a well-developed foliation. Together, evidence of initial grain shattering, followed by shear, grinding, and wear, suggests extensive transport distances (large strains). Textural transitions are often abrupt, indicating extreme shear localization during transport. Comparison of groundmass textures from dome lavas and fault gouge further suggests that brittle fracture was confined to the upper 400-500 m of the conduit. Observed magma extrusion (ascent) rates of ~7 m/d (8×10 -5 m/s) permit several weeks for magma ascent from ~1,000 m (where groundmass crystallization becomes important) to ~500 m (where solidification nears completion). Brittle fracture, cataclastic flow, and shear localization (slickenside formation) probably dominated in the upper 500 m of the conduit. Comparison of eruptive conditions during the 2004-6 activity at Mount St. Helens with those of other spine-forming eruptions suggests that magma ascent rates of about 10 -4 m/s or less allow sufficient degassing and crystallization within the conduit to form large volcanic spines of intermediate composition (andesite to dacite). Solidification deep within the conduit, in turn, requires transport of the solid plug over long distances (hundreds of meters); resultant large strains are responsible for extensive brittle breakage and development of thick gouge zones. Moreover, similarities between gouge textures and those of ash emitted by explosions from spine margins indicate that fault gouge is the origin for the ash. As the comminution and generation of ash-sized particles was clearly a multistep process, this observation suggests that fragmentation preceded, rather than accompanied, these explosions.


In modern trends, the voltage profile has become increasingly critical when incorporating wind turbine energy sources because of changes in fault ride-through capabilities throughout voltage reaction. Ripple, voltage magnitude changes, and injected harmonics due to conversion switches are power quality issues for grid-integrated doubly fed induction generators (DFIG) wind sources. In this study, FACTS (flexible alternating current transmission system) devices like the static VAR compensator (SVC), thyristor controlled series compensator (TCSC), unified power flow controllers (UPFC), and static synchronous compensators (STATCOM) are used to stabilise wind energy with DFIGs. The simulation test cases using MATLAB also analyse three lines to ground fault (LLL-G) of fault measures, which showed a 9 MW that transferred to utility grid. Therefore, it is suggested to inject or absorb reactive power to stabilise the system using moth flame optimization with firebug swarm optimization (MFO-FSO). The simulation results clearly demonstrate that the proposed MFOFSO based STATCOM devices outperform the current nonlinear generalized predictive control based STATCOM, which only achieves 0.9815 per unit voltage stability, by achieving a higher voltage profile of 0.9925 per unit voltage stability with a reactive power injection of 1.82 MVAR.


We prove an asymptotic formula conjectured by Manin for the number of $K$-rational points of bounded height with respect to the anticanonical line bundle for arbitrary smooth projective toric varieties over a number field $K$.


Abstract Twelve Ctenomyces (Arthrodermataceae, Onygenales) strains were obtained and identified during a survey of keratinophilic fungi in soils from China. We used molecular identification combined with morphological evidence to delimit species, circumscribing five species in the genus. Three new species are herein described: C.albussp. nov., C.obovatussp. nov. and C.peltricolorsp. nov. We also described, illustrated and compared the novel species with related species in the morphology.


Objective To explore the adverse effect of abnormal metabolism of glucose during gestation on pregnant outcomes of pregnant women and peripartum babies. Methods 10 809 pregnant women at gestational age of 24~28 weeks were screened with 50g glucose challenge test (GCT), and subjects with a positive reaction would receive further 75g oral glucose tolerance test (OGTT).Based on the results of OGTT, they were divided into three groups: normal glucose tolerance(GNGT), gestational diabetes mellitus (GDM), and gestational impaired glucose tolerance (GIGT). Results Of 10 809 pregnant women, 66 women and 270 women were diagnosed as GDM (0.61%) and GIGT(2.5%), respectively.The incidences of postpartum hemorrhage, cesarean section, pregnancy-induced hypertension, polyhydramnios, fetal macrosomia, premature delivery, neonatal hypoglycemia were higher in GDM group than in GNGT group (P0.05). The incidences of cesarean section, polyhydramnios and fetal acrosomia were higher in GIGT group than in GNGT group (P0.05) .The incidence of low birth weight was lower in the GIGT group than in GNGT group (P0.05) . Conclusions Abnormal metabolism of glucose in pregnancy can produce adverse impact on mothers and neonates.Therefore, it is very important to make detection, diagnosis and treatment for abnormality of glucose metabolism during pregnancy.


The anodic oxidation of concentrated l-alanine on smooth electrodes such as platinum and glassy carbon electrodes was studied. Contrary to the previous studies performed up to now with diluted l-alanine, the electrochemical process generated here results in a completely different situation. The oxidation on smooth platinum was carried out by electrochemical quartz crystal microbalance (EQCM) coupled to cyclic voltammetry technique. The effects of concentration, scan rate, and pH (zwitterion at pH = 6 and alkaline media at pH = 13) on potential values were examined. Glassy carbon and smooth gold electrodes showed the same behavior as on smooth platinum electrode. Spectroscopic analysis such as attenuated total reflectance FT infrared spectroscopy (ATR-FTIR) and X-ray photoelectron spectroscopy (XPS) were used to characterize the resulting thin film coatings. The presence of peptide bonds is clearly highlighted. DFT modelization of poly(alaninate) strand on Pt(001) coupled to spectroscopic measurements are ...


Rebels that fight near or capture cities gain more concessions from the government than those that remain in the periphery. Yet, not all groups challenge urban centers. Previous scholarship expects rebel strength to explain this strategic decision. However, weak rebel groups challenge cities, too. Our approach focuses on the conflict process more broadly. We argue that as the network of rebels challenging the government increases, opposition groups become more likely to attack cities as either they become emboldened, given the government's disadvantage in multi-front wars, or they are propelled to strategic and resource centers in competition with the other groups. Statistical analysis of all African conflicts from 1989-2009 strongly supports this logic, while an exploration of most typical cases highlights each of these mechanisms in practice. This project thus links literature on civil war tactics and conflict contagion.


High-voltage design optimization requires a fundamental understanding of electrical breakdown mechanisms under different stress situations. The impulse withstand voltage is normally used as dimensioning criterion for medium voltage air-insulated systems as flashover mechanisms in air are rapid. Prediction of withstand voltage relies on streamer inception and propagation models that are not always sufficiently accurate. Positive impulse voltage experiments were performed on a rod-plane gap with a dielectric barrier at different positions parallel to the ground plane. Streamers initiate from the rod tip and propagate in the field direction. Charge deposited on the dielectric surface changes the field situation and can result in a higher inception voltage. The streamer propagation was recorded with a fast ICCD camera. Finite element method field simulations of the background field were used to evaluate the effect of a barrier surface potential on the streamer inception voltage. Streamers reach the ground electrode without initiating electrical breakdown. The discharge activity from the rod was reduced by deposited charge on the barrier.

As South Africa is situated on one of the world's major shipping routes, oil pollution consequent upon maritime operations is believed to be not inconsiderable. The enrichment of petroleum compounds in the sea surface microlayer relative to the bulk water phase is expected to affect adversely the wide variety of neustonic organisms associated with the microlayer du ring part or the whole of their life cycles. Sampling was accomplished by momentary application of a Teflon disc to the sea surface from a moving vessel. Samples were subjected to hydrolysis, fractionated on silica gel and analyzed by capillary column gas chromatography. The presence of petroleum in samples was inferred from the molecular weight range of n-alkanes in the saturated hydrocarbons fraction, together with the confirmatory presence of unresolved complex mix tures (UCMs) in b o th saturated and polycyclic aromatic hy droc arb ons (PARs) fractions. Comparisons between samples were made on the basis of carbon-number preference indices, shapes of n-alkane distributions, and ratios of total alkanes to total PARs and total n-alkanes to alkane UCMs. The concentration of total petroleum hydrocarbons in the micro layer ranged between 25 and 5,600 mg/l (i.e. 0.4 to 84 mg/m2). This study shows the usefulness of simple gas chr omatography in the initial stages of oil-spill investigations, p rior to application of GC/MS or other advanced techniques.


The evolution of the main yeast species related to table olives ( Pichia anomala, Pichia membranaefaciens, Pichia minuta, Saccharomyces cerevisiae, Candida diddensii, Candida famata , and Debaryomyces hansenii ) at low temperature ( 7 oC ) and different physico-chemical brine conditions was studied, using the log of the relative growth as response. In general, the NaCl concentration had a reduced effect, which was slightly greater at pH 3.5, although it was never significant. The effects of pH and type of acid were significant: the presence of acetic acid always diminished the yeast population with time; however the population was maintained, or even slightly increased, in the presence of lactic acid. Such effects were higher at pH 3.5 than at pH 4.0. The behaviour of the yeast species was diverse. Sacch. cerevisiae , P. nmembranaefaciens , C. famata y Deb. hansenii diminished with time in 8 % NaCl. The yeast population markedly decreased at pH 3.5, mainly in the case of Sacch. cerevisiae and C. famata . The presence of acetic acid decreased the yeast population in most species and always lead to a progressive diminution of it with time. No differences between species due to lactic acid was observed. These results can be of interest for the development of commercial presentations of table olives to be preserved at low temperature and with a reduced level of sodium.


This paper presents a novel approach to the attitude determination problem of space vehicles. The proposed algorithm utilizes a modified Genetic Algorithm (GA) to solve the "lost in space" star pattern recognition problem associated with star tracker attitude determination systems. Characteristics of the stars that are visible within the Field of View (FOV) – reflected on an image taken by the onboard star tracker – are formulated using simple geometric descriptions. The proposed GA minimizes the discrepancy between the characteristics of the stars inside the actual FOV and a candidate FOV selected from the on board stored star map. The global minimum of the discrepancy represents the inertial coordinates of the FOV bore-sight. The concept of a Spiral Genetic Algorithms (SGA) is proposed where the search area decreases for consecutive GA, with consequently tighter constraints, making it converge to the desired location. Also the algorithm presented has the capability of determining the rotational angle between the spacecraft's coordinate system and that of a real star map. Simulation results indicate competitive results to current star trackers in terms of accuracy.

As a management consultant, my main interest is in the sound formulation and effective execution of business strategies. My consulting engagements often call the sales group into play since that is where execution succeeds or fails – at the point of customer contact. Thirty-eight years' experience with more than forty sales teams from a dozen industries has taught me what's required for consistently superior sales performance: a high-performing sales ecosystem. "What's an ecosystem?" you ask. Well, at its simplest, it consists of organisms and their environment. Picture the glass bubble, the fully enclosed habitat in which organisms are born, develop and thrive without ever leaving. All that's needed is contained within. It is a complete ecosystem. As several respected writers 1 have observed over many years, performance is a function of individual and environmental variables. For consistent execution leading to high levels of sales performance, sales people must have the necessary talent and they must have a high-functioning, well-developed sales ecosystem around them. Frequently, I find execution weaknesses do not tie to the talent base but to the supporting elements that are supposed to enable talent to execute effectively. In other words, it is most often the environmental variables that hinder superior sales execution. Why? Because the sales ecosystem is not being managed.


We have measured nonlinear-optical effects in ion-exchanged channel waveguides fabricated in semiconductor-doped glass. The nonlinearity is manifested as optically induced saturable absorption displaying a resonant enhancement. The relaxation time of the nonlinearity was found to be tens of picoseconds. The relaxation time also exhibited wavelength dependence. Waveguide transmission and pulse-probe experiments using a picosecond mode-locked dye laser were used to carry out these measurements.


This paper outlines an effort to develop an automated eddy current method assisted by a self-aligned manipulator scanning along the disk rim of a Westinghouse turbine. The light-weighted manipulator was mainly designed for inspecting blades on the L-2 stage disk where root cracks were most frequently found during ISI. A mock-up with changeable blades was used to assess the performance of this technique by a statistical method. Experimental results showed that the POD of this technique agreed well with that originally proposed. The technique was also proven feasible in field trials.


We demonstrate theoretically and experimentally the fine lateral circular birefringence of uniaxial crystal plates, an example of the spin — Hall effect of light. We report experimental observations this effect using polarimetric and quantum-weak-measurement techniques.


that observers started thinking there was a French exception only when people started saying there no longer was one: the title of the book, and its question mark, draws on a notion developed at the end of the 1980s that the French exception was no more. Can there be an end to something that did not take place? The authors themselves clearly wonder: an earlier version of the book, The French Exception (New York: Berghahn, 2005), had no question mark in its title. Nevertheless, from this uncertain area and contested phenomenon, a way of approaching French politics and society emerges. Looking at France open-mindedly from this perspective has perhaps a heuristic value; and we are treated to a series of examinations of France in thirteen chapters. There are chapters on the notion of 'l'exception', on social policy, culture, the extreme left, Europe, immigration, Islam, the media, post-colonialism, francophonie, and the presidency. There is further discussion of the issues by the co-editors in a wide-ranging Introduction and Conclusion. On the whole, the chapters constitute a series of interesting discussions of most aspects of French politics, policy, society, and social relations within France, and political relations outside France, from the colonial past, to Europe, and to globalization. Having said all we have said earlier, when one reads this book, one begins to wonder if indeed there is some basis for France's claim to exceptional status. As is discussed in the volume, France's attitude to the state as fashioning the nation (rather than the other way round) is singular, its highly proactive attitude to its own cultural products is unusual, the virulence of its political extremes marks it out; all point to its difference. And France is pretty exceptional in the bold way in which it has regularly stood up to the United States, from Vietnam to Iraq. What are the reasons for this? Perhaps it is less to do with how France is than with how France thinks it is. The notion of the French exception informs the way France imagines itself, and creates perceptions and discourses that affect comportment. Overall, France, like everyone else, is adopting practices and institutions that integrate with the wider world; but the desire to be different, and the expectations of difference, seem to have created a characteristic Frenchness.

Artificial nacre-like graphene oxide paper has sparked great excitement in the scientific community for its unique properties. The preparation of a bioinspired high-strength nanocomposite paper via a simple vacuum-assisted assembly technique from graphene oxide (GO), tannic acid (TA) and Fe3+ ions is reported in this article. The fabricated papers were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), Fourier transformed infrared (FTIR) spectroscopy, X-ray photoelectron spectroscopy (XPS) and dynamic mechanical analysis (DMA). We show that Fe3+ ions only induce limited improvement in the mechanical properties of the graphene oxide paper, while the efficient cross-linking of neighboring sheets by Fe3+–TA complex network can significantly improve the fracture strength and Young's modulus of graphene oxide paper by 150% and 521%, respectively, with an optimal content of 5.7 wt% Fe3+. With general surface binding affinity, TA molecules can be adsorbed to GO sheets and provide binding sites for Fe3+. The Fe3+–TA coordinated compound serves as the "mortar" to stick the GO "bricks" together. The mechanical properties of our paper can be simply varied by controlling the cross-linking condition. The obtained nacre-like ultrastrong GO papers could find potential in energy and sustainability applications.


The author proposes an interpretation of the dielectric response of semiconductors in terms of a screened hopping model relating both to the horizontal transitions in bulk material and to the vertical transitions in space charge regions and at interfaces. This appears to be the only general model consistent with the totality of experimental observations on semiconductors that opens up a new field of theoretical investigations into the nature of electronic transitions in semiconductors and similar materials. It also provides a link with the new interpretation of the more general dielectric response of solids.<<ETX>>


We discuss a number of illuminating results for tight-binding models supporting a band with variable Chern numbers and illustrate them explicitly for a simple class of two-banded models. First, for models with a fixed number of bands, we show that the minimal hopping range needed to achieve a given Chern number C increases with C and that the band flattening requires an exponential tail of long-range processes. We further verify that the entanglement spectrum corresponding to a real space partitioning contains C chiral modes and thereby complies with the archetypal correspondence between the bulk entanglement and the edge energetics. Finally, we address the issue of interactions and study the problem of two interacting particles projected to the flattened band as a function of the Chern number. Our results provide valuable insights for the full interacting problem of a partially filled Chern band at variable filling fractions and Chern numbers.

Many applications use graphs to represent and analyze data, but the effective deployment of graph algorithms on many-core processors is still a challenge. Many-core devices offer higher peak performance than multi-core devices; however, many-core programming is still a specialized skill. While compilation and runtime frameworks for parallelizing graph applications on multi-core CPUs exist, there is still a need for comparable frameworks for many-core devices. We propose GRapid: a compilation and runtime framework that generates efficient parallel implementations of generic graph applications for multi-core CPUs, NVIDIA GPUs and Intel Xeon Phi. Applications are expressed using a platform-agnostic programming API. Our source-to-source compiler performs platform-specific code transformations and optimizations, handles data transfers between the host and the coprocessor, and generates several functionally-equivalent code variants for the target platform. Our runtime library provides an efficient dynamic memory management scheme for applications where the graph topology is modified during processing. We used the proposed framework to rapidly generate efficient implementations of four graph applications on different target processors. Such rapid prototyping and re-targeting capability has obvious programmability advantages, but it can also be used to quickly identify target processors that better match the application's computational needs.


Abstract : Microprocessors/computers now control many critical functions such as arming and functioning of fuzes. The Software Fault Tree (Soft Tree) begins like any Fault Tree, then continues through the software to the inputs and other electronics. The Soft Tree provides a means of analyzing the hardware/software interfaces and software, as well as, hardware and man/machines interfaces. The technique facilities the systematic search for safety critical decision points and nodal points in the software. The Soft Tree will also highlight areas where a single bit error can cause a hazardous condition. The Soft Tree is similiar to the Fault Tree in nature; therefore, engineers can use the technique now. Keywords: System supply; Weapon safety; Robotics.

Pancreatic islet cells are especially vulnerable to damage by various oxygen derived free radicals. Free radicals generated by cells of the immune system play a key role in the cellular pathogenesis of type I diabetes (Rabinovitch 1992). Furthermore, a variety of diabetogenic drugs, most notably alloxan (Sakurai and Miura 1989) and streptozotocin (Nukatsuka, Sakurai, Yoshimura, Nishida and Kawada 1988), exert their effects via free radical generation. To combat freeradical damage, islets contain various scavenging enzyme systems, among the most prominent of which is superoxide dismutase (SOD) (Asayama, Kooy and Burr 1986; Crouch, Gandy, Kimsey, Galbraith, Galbraith and Buse 1981; Grankvist, Marklund and Taljedal 1981). This enzyme, which scavenges superoxide radicals, can protect against both alloxanand streptozotocin-induced diabetes in vivo (Papaccio, Pisanti and Frascatore 1986; Thaete, Crouch, Buse and Spicer 1985) and islet B-cell destruction in vitro (Fischer and Hamburger 1980).
