Interpolation of aliased seismic data constitutes a key step in a seismic processing workflow to obtain high quality velocity models and seismic images. Leveraging on the idea of describing seismic wavefields as a superposition of local plane waves, we propose to interpolate seismic data by utilizing a physics informed neural network (PINN). In the proposed framework, two feed-forward neural networks are jointly trained using the local plane wave differential equation as well as the available data as two terms in the objective function: a primary network assisted by positional encoding is tasked with reconstructing the seismic data, whilst an auxiliary, smaller network estimates the associated local slopes. Results on synthetic and field data validate the effectiveness of the proposed method in handling aliased (sampled coarsely) data and data with large gaps. Our method compares favorably against a classic least-squares inversion approach regularized by the local plane-wave equation as well as a PINN-based approach with a single network and pre-computed local slopes. We find that by introducing a second network to estimate the local slopes whilst at the same time interpolating the aliased data, the overall reconstruction capabilities and convergence behavior of the primary network is enhanced. An additional positional encoding, embedded as a network layer, confers to the network the ability to converge faster improving the accuracy of the data term.

Objective To study the antagonism and mechanism of Lactobacillus Salivarius ssp.salivarius ZDY162a against mytoxin-producing Fusarium.Method Fusarium graminearum and Fusarium oxysporum were adopted as the indicator strains to test the inhibition effect of metabolites of L.salivarius ssp.salivarius ZDY162a on spore germination,spore growth and mycelium growth.Result 10% of the spent culture supernatant(SCS) of L.salivarius ssp.salivarius ZDY162a could inhibit the spores germination of Fusarium graminearum by 83% and Fusarium oxysporum by 50%,respectively.The SCS inhibited remarkably the growth of spores in 24 h and that of mycelia of Fusarium in 96 h.Conclusion Some organic acids produced by L.salivarius ssp.salivarius ZDY162a were probably playing an primarily role in inhibiting the growth of Fusarium graminearum and Fusarium oxysporum.


. The purpose of this study is to evaluate the effect of payment system innovation on retailer efficiency because of the implementation of the National Payment Gateway in Indonesia. We use a two-stage approach at the individual and national levels by adopting an efficient frontier approach using the Malmquist Productivity Index (MPI) based on data envelopment analysis (DEA) to measure the productivity of 5 Indonesian retailers during 2015–2020. Total assets, total expenses, and number of outlets are considered as inputs while net income, profit, and earnings per share (EPS) are considered as outputs. Result indicated that there was no significant improvement after GPN implementation in 2017. There was a lower improvement in MPI (1,0085971) during 2018–2020 as a period after GPN implementation as compared to MPI (1,0834615) during 2015–2017 as a period before GPN implementation. This study, however, is unable to prove that the implementation of GPN can improve retailer efficiency in Indonesia. The study's findings can help in our understanding of the efficient frontier, which can explain the relationship between payment system innovation and retailer efficiency. This willprovideinformationforpaymentsystempolicymakerstoconsiderretailindus-try impact when setting up and/or initiating payment system innovations in the future.

Abstract Long-term lifecycle monitoring of federally endangered southern steelhead trout (Oncorhynchus mykiss) in Topanga Creek provides a unique opportunity to examine the health and abundance of a steelhead population before (2008--2011) and during (2012--2016) a prolonged drought. We found that the five-year drought resulted in a substantial and significant decline in available wetted habitat suitable for rearing and upstream migratory access for anadromous adults. The response of the steelhead population has been a significant reduction in anadromous spawning, distribution of rearing, and abundance of all life stages of anadromous and resident steelhead. After five years of drought a population that exceeded 325 individuals in 2008, now numbers fewer than 50 fish, and appears to be at extremely high risk of extirpation. Acknowledging the possibility of increased drought regionally and globally, the need to bolster southern steelhead resiliency to additional disturbance is paramount.

1260 © 2008 The Authors JEADV 2008, 22, 1236–1278 Journal compilation © 2008 European Academy of Dermatology and Venereology Patchy AA was the only clinical type in all patients. Duration of the current episodes of the disease in patients ranged from 2 months to 3 years (mean: 11months). The mean serum Se level were significantly lower in AA patients (62.1 ± 13.3 μg/L), compared with control group (88.3 ± 13.2 μg/L) (P < 0.0005). We did not observe any significant association between the extent of AA and serum Se level (P > 0.05). (Table 2) To our knowledge, there is no report determining the serum Se level in patients with AA, except a previous report of investigation of trace element concentrations in serum of patients with AA by Mussalo-Rauhamaa et al. They obtained low Se concentration in serum samples of a few patients and suggested this fact may be as the result of low Se content in the Finnish population due to the scanty content of Se in their foods. Although in the present study, the correlation between the severity of the disease and serum Se level was not significant; however, the majority of our patients had mild AA and comparisons are hampered by low statistical power because of the lack of patients with moderate to severe types in our study. In this study, serum Se level in Iranian patients with AA was lower significantly compared with control-matched subjects, and we can put forward the hypothesis that Se may play a role in the pathogenesis of the disease.


Depression and anxiety often coexist during pregnancy, potentially increasing the risk of adverse delivery outcomes like preterm birth and low birth weight. However, our understanding of the frequency, patterns, and factors influencing comorbid anxiety and depression is limited, especially in low- and middle-income countries. This study aims to: (1) explore the prevalence and patterns of prenatal anxiety and depressive symptoms among pregnant women in the mild-to-severe and moderate-to-severe categories; (2) examine the prevalence and patterns of antenatal anxiety and depressive symptoms among pregnant women in the mild-to-severe category; (3) investigate the association between frequent folic acid use and prenatal anxiety and depression symptoms. The study adopted a retrospective cohort approach and enrolled a diverse sample of 500 pregnant women receiving care at the Women and Children's Hospital in various locations across the center and south of Iraq. Results indicated that women who did not consume folic acid during pregnancy exhibited higher rates of comorbid anxiety and depression. Specifically, this pattern was observed among women in the age range of 20 to 29 years, those with a university degree, and those who had more than two previous children.


All coefficients interval number linear programming model with equality constrains and its solution method are discussed in this paper. A new solution method is presented to solve the all coefficients interval number linear programming model containing not only inequality constrains but also strict equality constrains. The characteristic of the method is via the optimal value of deterministic linear programming to get the equality constrains to satisfy the decision maker's preference. With the method, the decision maker can obtain a satisfactory solution. Finally, the application value of the method is given by a portfolio investment case. And the result shows that the method is scientific and feasible.


With the advancement in the network connectivity, services can be subscribed for limited period of time. Subscribing for certain services is always an economic option rather than owning them. Implementing adequate procedures in the establishments, meeting the access control policies is challenging. Although the essential procedures are implemented using the centralized scheme where the single central server cater to the access control requests and the authorization mechanisms with the help of the stored identifiable attributes of the workstations in the web. In our article, we are proposing a blockchain powered lightweight, decentralized and secure framework for mutually authenticating the participating entities and levy the access control model among them. In our protocol, the device administrators (DA) can maintain their signed device policies for any of its services in the blockchain network which increases its visibility to more subscribers and at the same time, DAs can get rid of tedious job of authenticating each and every user/subscriber. On the other hand, users can also come to know about the wide range of services provided by different service providers and can avail appropriate service with the optimal constraints. We used elliptic curve cryptography (ECC) to transmit the secret sign parameters which makes our protocol lightweight. Secret sign parameters are used to verify the signature of any entity at the other end.

In chick embryos, limited carbohydrate in‐ovo necessitates high rates of gluconeogenesis from amino acids and/or triglyceride‐glycerol for glycogen synthesis and other metabolic functions. The aim was to quantify gluconeogenesis and glucose carbon recycling during the latter stages of development in small versus large eggs. [U‐13C]Glucose (15 mg in 75 μL water) was injected into the amniotic fluid of small (54 to 58 g) and large (66 to 70 g) eggs for three consecutive days prior to tissue and blood collection on d 12, 14, 16 and 18 embryonic (5 eggs/age group). Blood was analyzed by GC‐MS for 13C‐mass isotopomer distribution in glucose, alanine, aspartate and glutamate. On d 16 and 18, embryo weights of small eggs were less than large eggs (17.8 and 20.6 g vs. 23.4 and 27.8 g; P<0.05). Gluconeogenesis (0.97 to 1.38 g/d) and glucose carbon recycling (30%) did not differ between small and large embryos; however, there was an increase (P < 0.01) in these fluxes from d 12 onwards. There was a significant contribution of glucose carbon to alanine flux (5 to 65%; P< 0.01), but only a small portion of aspartate (0.2 to 10%) and no glutamate derived from glucose. The latter indicates limited entry of glucose carbon into the Krebs cycle. In summary, small egg‐embryos maintained similar rates of gluconeogenesis compared to large egg‐embryos, despite their small embryonic size.


The Radar Level Gauging technology, invented back in the 70's, is since a number of years the industry standard in high-accuracy, custody transfer level gauging. This article describes the principles and corner stones of the radar technique and addresses practical oriented questions on antenna types, different tank types and integration of complementary sensors. A brief view over recent market studies is also presented.


The DNA topoisomerase II‐alpha (topo II‐alpha)‐targeting drug etoposide was recently shown to be an active agent in the combined chemotherapy of hormone‐insensitive prostatic carcinoma. Aside from being the molecular target of etoposide, topo II‐alpha is also a cell proliferation marker. Much experimental data indicate that cells sensitive to topo II‐targeting chemotherapeutic drugs are rapidly proliferating and show elevated topo II expression. There is little information concerning topo II expression in lesions of the prostate.


The trade-off between desirable public health outcomes and undesirable economic outcomes of anti-pandemic measures forces policy makers everywhere to seek the right combination of measures to balance the public health concerns against employment and income considerations. This article describes a novel input–output approach to assessing economywide costs of shutting down tourism and related sectors to curb the spread of COVID-19. Our framework allows for a decomposition of the total effects of shutdowns into sectoral output losses resulting from (i) suspension of the delivery of inputs to other sectors, (ii) termination of the demand for inputs produced by these sectors, and (iii) the interruption of payments to the owners of factors of production employed in the sectors ordered to shut down. We illustrate the use of this methodological framework to measure and decompose the effects of recent shutdown orders issued in Turkey, a country of major tourism activity.


The design technique, fabrication, and breakdown-test results are described of a low-loss SAW (surface acoustic wave) filter for use in mobile telephone equipment. A multitransducer structure was adopted to get a low-loss SAW filter composed of 13 transducers (seven unapodized and six withdrawal) formed on a 36 degrees YX-LiTaO/sub 3/ substrate. As a result, the pass band loss was from 1.8 dB to 2.2 dB. Because the filter was for use in the UHF band (800 MHz band), the fingers of each transducer were required to be of a hyperfine line width. To form such a transducer on the substrate, it is useful to use lift-off technology using deep-UV exposure.<<ETX>>


Duplications are rare congenital anomalies which can be found in the gastrointestinal system from mouth to anus. Bleeding, intussusception, intestinal obstruction, volvulus and malignancy can complicate cystic duplications. A perforated cecal duplication cyst was detected in a 7-year-old boy operated with the findings of acute abdomen. The cyst was totally excised and the case is presented as a rare cause of acute abdomen.. ©2005, Firat Universitesi, Tip Fakultesi


Finite size corrections in the calculation of nuclear level densities are considered within the framework of a Fermi gas model. A simple geometrical correction to the single particle density of states leads to an increase in the Fermi energy which drastically reduces the many body density of states. For light nuclei such as 24Mg, the nuclear level density at T≡3 MeVis reduced by roughly an order of magnitude when finite size effects are taken into account and the reduction is more pronounced in heavier systems such as 208Pb.


The reflection on the institutional capacities of the State and, specifically, of the Public Sector is an issue to be considered for countries that want to achieve a greater degree of development. Conceptual and practical efforts are a fundamental task; at this point, taking public investment as a reference constitutes a foundation of this process, since it is a bridge to achieve development objectives.Public investment, properly channeled, enables processes of well-being and competitiveness, through the creation of public value. This article synthesizes some questions about what could be called strategic public investment, especially that which helps to improvethe conditions of competitiveness and strengthen the conditions of sustainable development in the long term. There is a need for greater efforts to improve the destination of public investment so that it contributes to economic growth, strengtheningactivities or key areas for technological development, conditions for industrial parks or economic zones enable new ventures and strengthens national empowerment capacity. Collaterally, there are activities necessary for these purposes, such as the quality of public health, adequate infrastructure, modern sanitary systems and logistics for the mobilization of goods and resources, all part of the efforts that must be made from strategic public investment, whose destination must be clear and inadequate terms.


Summary Prolonged shedding of human coronavirus in hematopoietic cell transplant recipients was associated with initial high viral load, high-dose steroids, and myeloablative conditioning regimens. No substantial intrahost evolution of viral genomes occurred over time.


News coverage on Islam in newspaper publications in Malaysia has become part of Malaysian dailies since Islam is the official religion in Malaysia. A special section is allocated for Islamic teaching, forum or letter to Editors for certain days in a week. Perhaps the greatest innovation in coverage on Islam can be seen from how Malaysian reporters frame their stories, which many include the definition of religion, faith and moral choices in the secular world. News on Fatwa has, in short, become a major topic of discussion among Malaysian public once it is highlighted. It became an agenda for a period of time in most of the mainstream newspapers. This paper focuses on how the public perceived the news reporting made on fatwa in the Malaysian newspapers by looking at (i) the source of knowledge of the respondents, (ii) knowledge and understanding on fatwa, and (iii) correlation between level of education and understanding of fatwa news. Random samples of fatwa news on various issues were used as reference for the respondents. Then, a survey on 500 respondents was conducted randomly among Muslim public around Kuala Lumpur and the state of Selangor areas. This has helped in identifying the level of understanding and reactions of the public towards Fatwa issued by the National Fatwa Council of Malaysia. The findings also suggested small numbers of the news coverage on Fatwa has emphasized the significance of the Fatwa which, in the opinion of many far exceeds the important of the fatwa itself. This study may help to strategize the Fatwa Council in convincing the general public on Fatwa through news reporting because there had always been questions of reliability since there is no follow-up 1 Corresponding author: firstname.lastname@example.com VOL.9 (SPECIAL EDITION) NOV 2016 : pp 31-47 al-abqori vol 9.indd 31 10/26/16 11:01 AM Journal A̒bqari ~ Vol.9 (Special Edition), 2016 32 by the council to the public regarding Fatwa that has been issued by them.

This Letter presents a metamaterial‐based compact one‐unit‐cell epsilon negative zeroth‐order resonant antenna designed on a microstrip line. The size of the proposed antenna is only 7.85 mm × 18 mm (or 0.05λ0 × 0.12λ0) at 1.79 GHz owing to zeroth‐order resonance. Closed‐form design equations for the proposed antenna are provided based on the equivalent circuit employing transmission line theory considering radiation loss. The return losses based on circuit/EM simulations and measurement are in excellent agreement. The measured antenna bandwidth is 17 MHz (about 1%) and total gain is 2.6 dBi. © 2009 Wiley Periodicals, Inc.

The significance of glass beading has evolved over time but it is still a very important part of Kanien'keha:ka culture.


Indicator-based methods that enable inexpensive evaluations of pate nt rights appear to have great potential as management tools. However, as of today these methods still require refinement to satisfy companies' applied needs. This paper analyzes the validity of so -far untested indicators of patent value to enhance the quality of patent assessments using indicators. Following an overview of the state of the art, the article expands the theory by eliciting patent attorneys' strategies to maximize profits from protecting intellectual property. Inspirations for the computation of new value indicators are gathered. Then, based on a newly compiled data set consisting of 813 EP patents, the probability of an opposition against a patent is modeled by established and new value indicators. The untested indicators draw from publicly available procedural information as well as full-text documents. The results show that accelerated examination requests and qualified word counts are correlated with the opposition decision and enhance the quality of existing valuation methods.

1 Cardiac output, its distribution and tissue blood flows were determined with tracer microspheres in pithed rats during pressor responses elicited by either α1‐adrenoceptor agonists (cirazoline, phenylephrine) or α2‐adrenoceptor agonists (xylaxine, B‐HT 933). Two doses were used for each of cirazoline and B‐HT 933 and phenylephrine was investigated in the presence of propranolol (3 mg kg−1). The rats were pithed under halothane anaesthesia. 2 Cardiac output was increased by xylazine, the higher dose of B‐HT 933 and phenylephrine. Heart rate was increased by phenylephrine and the higher doses of both cirazoline and B‐HT 933. Stroke volume was greater in those groups given xylazine, phenylephrine and the higher dose of B‐HT 933 but was decreased in those animals given the higher dose of cirazoline. 3 Both α2‐adrenoceptor agonists increased the number of microspheres trapped in the lungs and the proportion of the cardiac output passing through the hepatic artery but decreased that flowing through the spleen and gastrointestinal tract. The higher dose of B‐HT 933 also decreased the fraction of cardiac output flowing to the kidneys but kidney blood flow was maintained as a result of the increased cardiac output. Also, this treatment reduced blood flow in the epididimal fat pads. 4 Both α1‐adrenoceptor agonists increased the fraction of cardiac output received by the coronary vasculature but the only other effect on distribution common to these agents was an increase in the percentage of the cardiac output passing to the hepatic artery. Cirazoline decreased the proportion of cardiac output distributed to the gastrointestinal tract and spleen but the total fraction of cardiac output passing to the hepatosplanchnic region was maintained as a result of the increase to the hepatic artery. 5 Cirazoline markedly reduced the proportion of the cardiac output received by the kidneys and absolute flow in these organs was only 1.4% of control after the higher dose of this agonist but flow at the lower dose was maintained by the higher cardiac output. 6 It is concluded that there is a significant contribution to the pressor responses elicited by α‐agonists resulting from an α‐adrenoceptor‐mediated increase in cardiac output that may result from greater heart rates or stroke volumes. Also, there is a differential distribution of α‐receptor subtypes throughout the vasculature which is especially noticeable in the kidneys.


The prevalence and severity of allergic diseases is still rising in those aged 11–25 years ( Venkataraman et al, 2018 ; Mallol et al, 2019 ). An estimated 800 000 teenagers in the UK have asthma. This figure could be higher as teenagers can have undiagnosed asthma ( Siersted et al, 1998 ; BTS/SIGN, 2019). A person-centred approach to all aspects of care is central to supporting adolescents to self-manage their asthma and therefore minimise concerns around morbidity and mortality. School nurses have a key role in communicating strategies that support self-management, and the use of tools can be helpful.


For developing a control system for these agitators, the analysis focused on the rheological characteristics of digestates, the open jet in non-Newtonian fluids and the flow conditions in a biogas reactor. In addition to a clearly visible shear-thinning effect, the viscoelastic proportion of these substrates was also determined. Depending on the stirrer speed and the rheology, the angle of spread varies and a reverse flow can occur directly at the stirrer. Therefore, not only can the position of the stirrer be used to optimise the flow field. The conical spreading of the liquid jet also enhance the mixing process. By using thrust measurements, their suitability as controlled process variables could be demonstrated.

Abstract ABSTRACT We studied the growth andsurvival of Spectacled Eider (Somateriafischeri) ducklings to30 days of age along the lower KashunukRiver on the Yukon-Kuskokwim Delta from 1995 to2000. We replicated this study at a second site,Kigigak Island, in 1999 and 2000. Age-adjustedestimates of duckling mass and survival at30 days posthatching were highly variable.Duckling survival was consistently higher onKigigak Island in 1999 and 2000, averaging67%, while survival on the Kashunuk Riveraveraged 45% during the same time period.Duckling survival was negatively related tohatching date. At the Kashunuk River site our datasupported models that indicated age-adjusted massvaried with habitat type and declined with hatchingdate. Ducklings from Kashunuk River were heavier in1999, while ducklings from Kigigak Island wereheavier in 2000. However, we found a positivecorrelation between 30-day duckling survival andage-adjusted mass, suggesting a localizedenvironmental effect on both parameters. Weconclude that predation may be the proximatemechanism of mortality, but habitat conditions arelikely the ultimate factors influencing ducklingsurvival. Geographic variation in rates of ducklingsurvival and apparent growth suggest that spatialheterogeneity in population vital rates isoccurring at multiple levels.

Farmer Groups are one of the forums for farmers to increase resources and production of agricultural products. Strong farmer groups will greatly contribute to improving the welfare of the Indonesian people. This study aims to rank farmer groups and evaluate their performance efficiency so that they are in accordance with the priority interests of each criterion unit to support the task of decision-makers in fostering farmer groups in an appropriate manner. Fuzzy Analytical Hierarchy Process (FAHP) Model - Data Envelopment Analysis (DEA) is a ranking method based on preference data in the form of fuzzy numbers. In this study, the AHP-DEA fuzzy method was modified to become AHP-DEA-CCR fuzzy (Charnes, Cooper, and Rhodes). The modification was carried out by weighting using entropy-based fuzzy AHP on the input and output models. The FAHP-DEA model developed successfully mapped 15 farmer groups into 3 groups based on 3 criteria, namely learning vehicles, cooperation vehicles, and production units. Based on performance efficiency in the 3 criteria, 2 strategies are obtained to increase their abilities. One scenario is to provide training to increase production units to farmer groups with DMU IDs 1, 2, 6, 4, and 3, provide counseling and training to increase the use of learning vehicles and provide training to increase the use of cooperation vehicles to farmer groups 10,11, 12, 14, and 15. The varying decision risk into 0.2 (pessimistic), 0.5 (moderate), and 0.8 (optimistic) do not have a significant effect on the decision maker's choice.


This study aims to investigate how the young students at a public school in Sao Paulo using the internet to realize their homework and thereby understand how they use the resources available on the internet as pedagogical tools. We started from the assumption that with the advent of the internet, something would change in the dynamic of the school, since the internet was a source of knowledge for students that would allow a dialogue with the school culture. It would be a mechanism could change the relationship that young people establish with the school knowledge, favoring the mobilization of students for learning. It was found, however, that using that young respondents make available resources is only instrumental and depends on the intuitive knowledge they already have and that are not learned at school. School activities are still being proposed in the same way as they were before the internet appear as a research resource. The school culture no dialogue with the knowledge taken from the internet by students, failing to relate to part of the culture of these students, some mobilized for school learning in the usual manner.


Knotted ribbons form an important topic in knot theory. They have applications in natural sciences, such as cyclic duplex DNA modeling. A flat knotted ribbon can be obtained by gently pulling a knotted ribbon tight so that it becomes flat and folded. An important problem in knot theory is to study the minimal ratio of length to width of a flat knotted ribbon. This minimal ratio is called the ribbonlength of the knot. It has been conjectured that the ribbonlength has an upper bound and a lower bound which are both linear in the crossing number of the knot.
In the first part of the paper, we use grid diagrams to construct flat knotted ribbons and prove an explicit quadratic upper bound on the ribbonlength for all non-trivial knots. We then improve the quadratic upper bound to a linear upper bound for all non-trivial torus knots and twist knots. Our approach of using grid diagrams to study flat knotted ribbons is novel and can likely be used to obtain a linear upper bound for more general families of knots. In the second part of the paper, we obtain a sharper linear upper bound on the ribbonlength for nontrivial twist knots by constructing a flat knotted ribbon via folding the ribbon over itself multiple times to shorten the length.


For the dense prediction tasks, we introduce modifications in the targets to make them more challenging. When predicting an image from a vector field, we introduce color in the output based on the target category. We determine the color in HSV space, where the value is the original grayscale value, the hue is c/10 for category c, and the saturation is set to one. The target is then converted back to RGB. Figure 2 shows a few input/target pairs.


Abstract: An improved model is proposed to approximate the actual Raman gain profile of silica, which in turn is used to calculate the power depletion of the shortest-wavelength channel due to all other channels in the system. In this improved model, the stimulated Raman scattering (SRS) effects from channels at the tail of Raman gain profile are taken into account. A statistical analysis is done for the SRS crosstalk in a wavelength division multiplexed system including modulation statistics. The bit error rate and power penalty are estimated, where the improved model for the Raman gain spectrum is used. Key Words: Bit error rate, power depletion, power penalty, Raman gain, stimulated Raman scattering, wavelength division multiplexing. 1. INTRODUCTION Optical Wavelength Division Multiplexed (WDM) system effectively utilizes the enormous bandwidth of an optical fiber and hence meets the demands for large transmission capacity of multimedia communication [1]. However, fiber nonlinear effects limit the performance of a high power optical WDM system. Among the nonlinear effects, the Stimulated Raman Scattering (SRS) is the ultimate power-limiting phenomenon [2]. The SRS causes power transfer from shorter-wavelength WDM channels to longer-wavelength WDM channels and thus induces interchannel modulation between each WDM channel [3]. The optical power limits are calculated by the worst-case assumption that all WDM channels are synchronized and transmitted at ONE level simultaneously [4]. In all the calculations of Raman crosstalk, the experimentally found Raman gain profile of silica reported in [5] is approximated by a triangular function, where the peak Raman gain occurs at 15 THz spacing between channels and no Raman gain is assumed at larger spacing [6]. The results so far reported in literature based on this approximation are sufficiently accurate as long as the bandwidth of the fiber amplifier available currently is concerned [1]. However, for future wideband WDM systems, this approximate model of Raman gain requires to be modified. The probability density function (PDF) of SRS induced crosstalk has been developed in Ref. [7]. But the complete performance evaluation based on the statistical analysis of the Raman crosstalk is yet to be reported. The objective of this paper is to develop an improved model for the Raman gain profile, and, accordingly, to calculate more accurately the power depletion of the shortest-wavelength channel due to the SRS effects from all possible channels in a wide-band WDM system. A statistical analysis is presented to estimate the bit error rate (BER) of a WDM system based on the improved model for the Raman gain profile. Finally the sensitivity penalty suffered by the system due to SRS crosstalk is evaluated.


Severe headcutting at moderate flows within spillway channels at public and private reservoirs have caused the Corps of Engineers to re-examine the processes causing channel erosion. The process of headcutting could result in undermining and failure of flood control structures. Flume experiments which simulated the flow over overfalls showed that a partial vacuum pressure may develop beneath the nappe of the overfalling water plume. This partial vacuum will cause the plume to be pushed (by the atmospheric pressure) closer to the face of the overfall and a reverse scour roller to undermine the materials of the overfall. The propensity for partial vacuum formation to cause rapid headcutting is more predominant during low to moderate channel discharges.


Equality (1) is because we assume that Yt and t are independent conditioned on x. Equality (2) follows from the consistency assumption. Finally, the last equation is composed entirely of observable quantities and can be estimated from data since we assume 0 < p(t = 1|x) < 1 for all x. Definition A2. Let p(x) := p(x|t = 1), and p(x) := p(x|t = 0) denote respectively the treatment and control distributions.


Objective To compare the effect of moist and dry wound healing therapy in the patients with secondary healing wound after abdominal operation.Methods 60 patients with secondary healing wound after abdominal surgery were divided randomly into treatment group and control group,with 31 cases and 29 cases respectively.Moist and dry wound healing therapy was applied to treatment group and control group respectively.Results The cure rate and total effective rate was 83.9% and 96.8% respectively in treatment group,and 51.7% and 69.0% respectively in control group;there was statistical difference between two groups(P0.05).The change dressing times and treatment duration of was(6.8±2.0) times and(16.2±4.0) days in treatment group respectively,and both were less than(26.6±6.8) times and(28.5±7.2)days respectively in control group(P0.05).Conclusions The moist wound healing therapy can achieve high total effective rate with less times of change dressing and short treatment duration.It is superior to the dry wound healing therapy for abdominal operative patients with secondary healing wound,and is worth popularizing.


Self-calibration algorithms are useful tools for different applications, whenever a geometrically known target cannot be used. This paper considers self-calibration algorithms for image-based measurement systems. After a brief theoretical introduction, a solution for the correction of the lens distortion is presented based on a genetic algorithm. A comparison of the performances achieved with different solutions and different values of the parameters is performed through several numerical tests, including the simulation of random errors in the localization of features, and a procedure for the evaluation of the performances achievable after a 3-D reconstruction of points is presented.


In this paper, we present a preliminary experimental study of a wakefield accelerating scheme that uses an electron pulse train to produce wakefields that increases the transformer ratio greater than 2 by appropriate bunch spacing and current ramp. A dielectric structure was designed and fabricated to operate at 13.625 GHz with dielectric constant of 16. The structure will be excited by two beams with the first and second beam charge ratio of 1: 3 for the initial experiment. The expected transformer ratio is 3 and the setup can be easily extended to the case of 4 pulses which develops a transformer ratio of more than 7. Dielectric structure cold test results show that the tube is within the specifications. A set of laser splitters was also tested to produce ramped bunch train of 2 pulses. Overall design of the experiment and initial results will be presented.

Abstract Loss of Dungeness crabs Cancer magister in derelict crab traps was estimated from catches and mortality in 24 simulated lost traps at two locations in Washington State. Equal numbers of recreational and commercial crab traps were initially baited and monitored weekly by divers until the bait was consumed and were monitored biweekly thereafter for 1 year. Dungeness crabs caught in the traps were individually tagged. Catch, escapement, retained catch, and mortality rates were estimated. The traps caught 1,077 Dungeness crabs, of which 500 (46%) died and 421 (39%) escaped. Mortality of sublegal males and females was expressed in legal male equivalents. The overall retained catch of Dungeness crabs (caught minus escaped) was 0.082 crabs·trap−1·d−1. After an initial lag, the cumulative daily mortality rate of Dungeness crabs rose steadily to 0.058 crabs·trap−1·d−1. An estimated 12,193 traps are lost annually in Washington waters of the Salish Sea, and the estimated trap fishing duration was 126 d for ...


We have investigated iron‐doped semi‐insulating and conducting InP using a variety of characterization techniques. The occupation of the iron acceptor level was determined from measurements of the Fe2+ intracenter absorption and the Fe3+ electron paramagnetic resonance signal. These iron concentrations were then related to the total iron content, the free carrier concentration, and the net donor concentration as determined from an impurity analysis. When comparing the sum [Fe2+]+[Fe3+] with the total iron content of the samples measured by glow discharge mass spectroscopy we find that below about 1×1017 cm−3 no significant formation of precipitates occurs. Analysis of the free carrier concentration in semi‐insulating crystals allows us to determine the temperature shift of the iron acceptor level with respect to the conduction band. We obtain a value of 4.7×10−4 eV/K somewhat larger than the band‐gap shift of InP (3.8×10−4 eV/K). Due to this temperature shift the thermodynamic position of the iron accepto...


Diversity of urban structures in Europe has its sources in cultural distinctness of different regions, in different pace of their development over millennia. Methods of designing towns in subsequent urbanisation periods differed. Nevertheless, frequently older structures were adapted to new needs. The question concerning the ideal of the European city remains open - is impossible to define one dominating spatial model encountered everywhere, despite attempts of ancient powers (Imperium Romanum), and by 20th -century totalitarian systems. The latter largely contributed to interruption of continuity of cities' historical development, especially in Central and Eastern Europe. Warfare and scale of destruction of the spatial/social structure in many cities in 1939-1945 were unprecedented in the European history. Examples of metropolises practically wiped off from the face of the earth, like Warsaw or Dresden, are common knowledge. This fate was shared by many other towns, especially in the Polish-German borderland. Their reconstruction after the war caused complete transformation of their urban/social structure. The study focuses on Kamień Pomorski, situated on a headland at Kamieński Lake, separated from the Baltic Sea by Wolin island. Before the war it was one of the nicest port towns in Pomerania, with history reaching back to the early Polish state and the clash of Slavic, Scandinavian, and German influences. The town, an episcopal see, bloomed in the medieval and modern times under the Pomeranian, Brandenburgian, and German rule. At the end of the WWII the centre was ruined over several days. Some religious and secular buildings survived. Traditional economic foundations of the local population, moulded for centuries, and the corresponding port structure, were nearly completely destroyed. Almost complete replacement of the local community, not fully grasping the local spatial, natural and landscape conditions, was connected with introduction of centrally planned socialist economy. The town changed its character, despite maintaining and developing some of its previous functions (e.g. health resort). Kamień Pomorski was reconstructed in forms not corresponding to traditional ones (prefabricated blocks of flats), although respecting previous transport/urban layout, which is an advantage. There were attempts to restore the most important preserved monuments –cathedral, town hall, several sections of city walls. In time these efforts brought the expected effect. In recent years several investments were implemented, referring to historical spatial layouts, following the rules of retroversion and revealing some relics. The port function was restored – predominantly as a recreational yacht and water sports marina, popular in high season. Some waterfront boulevards were renovated. Promenades are being built, the spa park is to be revitalised. To conclude, it should be stated that improvement of public spaces is observable in Kamień Pomorski, just like in its green areas and waterfront edge. Renovations of pre-war tenements and villas and growing abundance of services activating the public domain cannot be disregarded. It seems that despite enormous war destructions, which changed the appearance of the town forever, after many decades Kamień Pomorski has become vivid again.

The vast majority of bilingual studies involve two spoken languages. Such "unimodal" bilingualism automatically entails a severe production constraint because one cannot physically produce two spoken words or phrases at the same time. For unimodal (speech-speech) bilinguals, there is a single output channel, the vocal tract, for both languages. In contrast, for bimodal (speechsign) bilinguals, there are two output channels: the vocal tract and the hands. In addition, for unimodal bilinguals both languages are perceived by the same sensory system (audition), whereas for bimodal bilinguals one language is perceived auditorily and the other is perceived visually. In this article, we present a preliminary investigation of bimodal bilingual communication among hearing people who are native users of American Sign Language (ASL) and who are also native English speakers. First, it is important to emphasize that American Sign Language has a grammar that is independent of and quite distinct from English (see Emmorey (2002) for a review). For example, ASL allows much freer word order compared to English. English marks tense morphologically on verbs, whereas ASL (like many languages) expresses tense lexically via temporal adverbs. Conversely, ASL contains several verbal aspect markers (expressed as distinct movement patterns superimposed on a verb root) that are not found in English, but are found in many other spoken languages (e.g., habitual, punctual, and durational aspect). Obviously, ASL and English also differ in structure at the level of phonology. Signed languages, like spoken languages, exhibit a level of sublexical structure that involves segments and combinatorial rules, but phonological features are manual rather than oral (see Brentari (1998), Corina & Sandler (1993) for reviews). Finally, English and ASL differ quite dramatically with respect to how spatial information is encoded. English, like many spoken languages, expresses locative information with prepositions, such as "in," "on," or "under." In contrast, ASL encodes locative and motion information with verbal classifier constructions. In these constructions, handshape morphemes specify object type, and the position of the hands in signing space schematically represents the spatial relation between two objects. Movement of the hand specifies the movement of an object through space (within whole-entity classifier constructions, see Emmorey, 2003). Thus, English and ASL are quite distinct from each other within phonological, morphological, and syntactic domains. In the current study, we chose to examine hearing ASL-English bilinguals because although Deaf signers are generally bilingual in ASL and English, many Deaf people prefer to read and write English, rather than use spoken English. Also, Deaf individuals do not acquire spoken English in the same way that a second language is acquired by unimodal bilinguals. For example, early speech bilinguals may be exposed to two languages in the home or one language may be used in the home and another in the community. In contrast, spoken language is not accessible in the environment of a deaf person and deaf children require special intervention, including training in speech articulation, speech perception, and lip reading, unlike hearing children acquiring a spoken language (see Blamey, 2003). Therefore, we examined hearing bilinguals who have Deaf parents for whom speech and sign are equally accessible within the environment. Bimodal bilingual children acquire a signed language and a spoken language in the same way that unimodal bilingual children acquire two spoken languages (Petitto, Katerelos, Levy, Gauna, Tetreault, & Ferraro, 2001; Newport & Meier, 1985) To our knowledge, this is the first study to examine bilingual communication in adults who acquired both signed and spoken languages naturally without explicit instruction. Hearing adults who grew up in Deaf families constitute an important bilingual community. Many identify themselves as


Interest in h-BN is driven by the combination of several of its characteristics like structural compatibility with graphene, chemical inertness, large band gap of about 6 eV and unique optical properties. These capabilities make it interesting as support for graphene in devices and also as clean, flat insulating environment for 2D materials. However, in order to make h-BN relevant for real world applications, scalable synthesis routes are needed. As a consequence, we have developed a promising approach to synthesize pure and highly-crystallized h-BN crystals, which can be further exfoliated into high quality, ultrathin, uniform Boron Nitride NanoSheets (BNNSs) [1]. This new accessible production process represents a relevant alternative source of supply in response to the increasing need of high quality BNNSs. The synthesis strategy is based on a unique combination of Polymer Derived Ceramics (PDCs) route with Spark Plasma Sintering (SPS) process [2]. Through a multi-scale chemical and structural investigation, it is clearly shown that obtained layers are large, defect-free and well-crystallized, which are key-characteristics for a subsequent exfoliation into relevant BNNSs.


In field conditions, the effect of plant growth regulators Ivin (N-oxide-2,6-dimethylpyridine), Methyur (sodium salt of 6-methyl-2-mercapto-4-hydroxypyrimidine), Kamethur (potassium salt of 6-methyl-2-mercapto-4-hydroxypyrimidine) on growth and productivity of sunflower (Helianthus annuus L.) variety Bastion was studied. The growth-regulating activity of plant growth regulators Ivin, Methyur and Kamethur was compared with the growth-regulating activity of the auxin IAA (1H-Indol-3-yl)acetic acid). It was found that the treatment of seeds before planting in the soil with water solutions of Ivin, Methyur and Kamethur, used at a concentration of 10-7M, contributes to an increase in morphological parameters (length of shoot and root, fresh weight of plant and basket) and biochemical parameters (content of chlorophylls a and b, and carotenoids) of sunflower (Helianthus annuus L.) variety Bastion grown in field conditions for 3 months. The growth-regulating activity of plant growth regulators Ivin, Methyur and Kamethur was higher than the growth-regulating activity of the auxin IAA used at the same concentration of 10-7M. The obtained results confirmed the possibility of using plant growth regulators Ivin, Methyur and Kamethur to increase the length of shoot and root, fresh weight of the plant and basket, and the content of chlorophylls in sunflower (Helianthus annuus L.) variety Bastion.


This paper proposes a guideline to determine Thai elementary discourse units (EDUs) based on rhetorical structure theory. Carson and Marcu's (2001) guideline for segmenting English EDUs is modified to propose a suitable guideline for segmenting EDUs in Thai. The proposed principles are used in tagging EDUs for constructing a corpus of discourse tree structures. It can also be used as the basis for implementing automatic Thai EDU segmentation. The problems of determining Thai EDUs both manually and automatically are also explored and discussed in


The hysteresis loops and the saturation magnetization of the epitaxial Fe3O4 ultrathin films with different thicknesses grown on the GaAs (100) surface have been studied. The molecular magnetic moment of the ultrathin films was obtained from the data of the measured saturation magnetic moment of the films and the number of Fe ions in each film calculated from the measured thickness of Fe films before oxidation and film area. It was found that the values of the molecular magnetic moment of films with thicknesses of 4 and 6 nm were close to the theoretical bulk value of magnetite. For the film thickness of 8 nm, larger magnetization was observed probably caused by less oxidation of the deeper Fe layer. The maximum magnetic moment of the film of 2 nm thick was lower due to the structure imperfection. The low coercivity of the films indicated that the quality of the films was reasonably good.


A one-dimensional numerical model of soil-water movement based on the Richard's equation has been compiled from several sources. Soil hydraulic properties are defined for two local soil types (red-brown earths) from field measurements. Daily evapotranspiration, daily rainfall, root distributions for perennial pasture and depression storage for irrigation bay slopes are some of the inputs. The lower boundary condition allows upward and downward fluxes. This model is used to compare the effects of soil type, watertable depth, climatic variability and management to recharge. A two year period (April 1982 to April 1984) is simulated using recorded weather data and irrigation schedules to allow comparison of two different seasons. The factors considered have a dominant influence on recharge in the summer seasons. In the wet winter of 1983 recharge is determined to a greater extent by the parameters of the lower boundary condition.


Submitted for the MAR13 Meeting of The American Physical Society Interaction between Dirac fermions and phonons on the (001) surface of the strong 3D topological insulator Bi2Te3 COLIN HOWARD, MICHAEL EL-BATANOUNY, Boston University, FANG-CHENG CHOU, R. SHANKAR, National Taiwan University — We report on studies of the interaction of Dirac fermion quasiparticles with phonons on the (001) surface of the strong 3D topological insulator Bi2Te3. Studying this coupling is essential for determining the technological viability of this new class of materials. We employed inelastic helium atom scattering to determine surface phonon dispersions along the ΓM and ΓKM directions. In contrast to our previous studies on Bi2Se3, 1 which exhibited a strong Kohn anomaly at 2kF ≈ 0.2Å−1 in a low-lying optical phonon branch, the current results show a weaker Kohn anomaly at 2kF ≈ 0.1Å−1 in a similarly low-lying branch. The lower value of kF is consistent with the smaller carrier concentration in Bi2Te3 as evidenced by Hall conductivity measurements. Our results are further substantiated by lattice dynamical calculations performed within the pseudo-charge model. We also report on a detailed analysis of the electron-phonon coupling as a function of phonon branch index and wave vector utilizing the methods we recently developed.2 1Zhu, et al. Phys. Rev.

Abstract The outputs and mass median droplet diameters of useful aerosols and the effect of solvent evaporation on the concentration of nebulizer solutions have been measured for four nebulizers of designs which have been employed for inhalation studies. Outputs ranging from 2.3 to 30.4 microliters of solution per liter of jet air were observed, with corresponding mass median droplet diameters of 1.4 to 5.4 microns. For jet pressure drops of 2.5 to 30 psi, from 7 to 10 microliters of solvent (water), in excess of that associated with the aerosol, was carried away per liter of jet air. The effects of baffling and of augmenting the jet air with additional flow through a vent were also determined.


: Nutrition related non-communicable disease like diabetes, is the prominent source of mortality in the world. Most nutrition associated non-communicable diseases is end result of four specific behaviors (tobacco use, physical inactivity, unhealthy diet, and the harmful use of alcohol) that lead to 4 vital metabolic/physiological changes (raised blood pressure, overweight/obesity, raised blood glucose and raised cholesterol). The cross sectional study was conducted at West district in Zanzibar. Data were collected using WHO steps tools translated into the local languages. Individuals for the study were selected by random selection for interviewing and physical examination from the study base. Data were analyzed using SPSS for Windows version 16.0.The 100 respondents of the survey 36% were men and 64% were women in Wete district Zanzibar. The 58% of people did not understand about the diabetes type2 knowledge of which 23% were male and 35% female, 26% of respondents 8% male and 18% female had little knowledge about the diabetes type 2 while only 16% of had the knowledge about the type 2 diabetes 5% male and 11% female. Also the distribution of the various categories of risk factors is identified. Body Mass Index (BMI) was calculated for each participant as (weight in kilogram)/ (height in meter) ².The nutrition status of the people showed 4% male and 2% female are underweight, 14% male and 33% female are normal, 15% male and 25% female are overweight and 3% male and 4% female are obese. The magnitude of risk factors for NRNCDs is considerably high in the study population.

Spontaneous pneumothorax is a rare but very serious complication in patients with COVID-19 pneumonia. Although the mechanism of pneumothorax occurrence is not fully understood, it is thought that it may develop due to the diffuse alveolar damage caused by pneumonia, interstitial emphysema, bullae or alveolar rupture caused by persistent cough (Vega et al. 2020). Its timing is uncertain, and it may be the first admission complaint of patients (Abootalebi et al. 2021); it may also develop during outpatient follow-up (Gonz alez-Pacheco et al. 2021) or hospitalisation (Martinelli et al. 2020). According to the conducted studies, the incidence of pneumothorax in COVID-19 patients was 1% in those who need to be hospitalised, 2% in those who need to be hospitalised in the intensive care unit (ICU), and 15% in those who had mechanical ventilation requirement. Pneumothorax was found in 1% of patients who died due to COVID-19 pneumonia (Martinelli et al. 2020). However, no pneumothorax case associated with COVID-19 positivity in a pregnant patient has been reported in the literature. In this case, we wanted to present a 16-week pregnant patient admitted to the emergency department (ED) with complaints of dyspnoea, chest pain and cough and was diagnosed with pneumothorax and COVID-19 pneumonia due to the examinations performed in the ED. This case report is the first published report in the literature of a pregnant COVID19 patient who was presented to the ED with pneumothorax.


Abstract Background: Clinical data of patients with entro-, vasculo-, and neuro-variant possible Behçet's disease (BD) based on Japanese criteria has not yet comprehensively reported. Methods: This ongoing nation-wide registration has been carried out by the Japanese Ministry of Health, Labour and Welfare. The Ministry asked physicians who diagnosed a patient with confirmed or possible BD to register the patient data by filling out a registration form. The Ministry provided us with the dataset after unlinkable anonymization. We analyzed 2003–2014 database generated from the early stage new cases. Results: Among the 7950 analyzable cases, 694 (8.7%) had variant-type possible BD without satisfying complete/incomplete criteria. Of the 694 patients, 479, 46, and 169 had entero-, vasculo-, and neuro-variant possible BD, respectively. Out of these 694 patients, 35 (5.0%) and 154 (22.2%) satisfied the International Study Group criteria and the International Criteria of BD, respectively. Entero-variant possible patients rarely (1.8%) had ocular lesions. Patients with vasculo-variant possible BD were featured by low genital ulceration risk (6.8%) and frequent positive HLA-B51 (60.0%). Neuro-variant possible BD was featured by high median age at registration (48 year). Vasculo- (69.6%) and neuro-variant (68.6%) BD patients showed clear male dominance. Epididymitis was very rare among variant-type possible BD men. Conclusion: We analyzed 694 early-stage variant-type possible BD cases. We believe the data from our study will contribute to further international discussion regarding BD diagnostic criteria and clarification of the clinical presentations of the Japanese variant-type possible BD patients.


Abstract We describe some new methods for constructing discrete acoustic phonetic hidden Markov models (HMMs) using tree quantizers having very large numbers (16–64 K) of leaf nodes and tree-structured smoothing techniques. We consider two criteria for constructing tree quantizers (minimum distortion and minimum entropy) and three types of smoothing (mixture smoothing, smoothing by adding 1 and Gaussian smoothing). We show that these methods are capable of achieving recognition accuracies which are generally comparable to those obtained with Gaussian mixture HMMs at a computational cost which is only marginally greater than that of conventional discrete HMMs. We present some evidence of superior performance in situations where the number of HMM distributions to be estimated is small compared with the amount of training data. We also show how our methods can accommodate feature vectors of much higher dimensionality than are traditionally used in speech recognition.


In describing the Old Indo-Aryan of his time and area, Panini accounts for a contrast among three past tense forms: aorist, imperfect, and perfect. In this system, both imperfect and perfect forms are used with reference to acts that took place in the past excluding the day on which an utterance is made. They contrast, however, in that the perfect is reportative, used of an act the speaker has not witnessed, while the imperfect refers to an act the speaker did witness. The claim has been made that the reportative use of the perfect is not vouchsafed by textual evidence. This claim is shown to be false. I consider here a narrative in two versions showing precisely the contrasts for which Panini accounts. In addition, I suggest a series of historical developments in Indo-Aryan leading to the early Middle Indo-Aryan use of the aorist as the dominant past tense form.

This paper marks the early stages of understanding the molecular mechanisms of intracellular signaling activated by the extracellular matrix (ECM). I like it also as an exploration of a new area through closely linked questions. By 1991, many integrins had been cloned and their ECM ligand specificities studied. A trio of papers from 1989 to 1990 reported that integrin occupancy could affect complex cell behaviors, such as differentiation; however, the mechanisms of these behaviors remained unknown. In separate research, phosphotyrosinecontaining proteins had been observed to be concentrated in focal adhesions. In this paper, Guan et al. (1991) linked these areas by demonstrating that fibroblast adhesion to fibronectin correlated with dynamic, environment-dependent, tyrosine phosphorylation of a 120-kDa protein. The results included important clues for future researchers: multiple domains of fibronectin were needed for the strongest effect, and the cytoplasmic domain of β1 integrin was also necessary. The 120-kDa protein was identified as focal adhesion kinase in 1992 publications from other laboratories. By identifying an intracellular biochemical event correlated with ECM–integrin interactions and adhesive functions, this paper presaged multiple top-cited MBoC papers of the 1990s.


The popular LEPS surface for collinear reaction paths and a simple bent surface yielding a nonlinear saddle point geometry were used to examine the capability of the LEPS surfaces in describing the kinetics and dynamics of systems with noncollinear reaction paths. The parameters calculated for the atom−diatom Cl + ClH reaction include geometries, vibrational frequencies, and curvatures (to estimate the tunneling effect) along the reaction path, as well as variational transition-state theory rate constants and kinetic isotope effects. The collinear LEPS and the bent surfaces for this triatomic system show similar behavior, so similar behavior in noncollinear polyatomic reactions may be expected, with the consequence of saving time and computational effort.


In allusion to the issues in oil sampling test, analysis on sampling method, sampling system principle, choice of sampling spot, sample treatment and sampling safety is made and relative treatment measures are proposed. It is of significance to solve these issues in ensuring equity during oil custody transfer metering, eliminating dispute and guarantee accuracy and reliability of custody transfer metering data.


Abstract Child immunization is a cost-effective public health measure for reducing child morbidity and mortality. Child immunization coverage in Kenya has improved in recent years, with coverage rates for most vaccines exceeding 80%. However, there are still pockets of low coverage, particularly in remote or hard-to-reach areas. We implemented a community-based project to improve access and equity in child immunization services in three Kenyan counties (Nairobi, Wajir and Mandera). We trained health workers, promoted community acceptance, and provided logistical support to Ministry of Health (MoH) for child immunization services through community outreach centers. During the project period (January 2020 to February 2023), our project facilitated full immunization coverage for 93,879 children and we reached 200,554 community members whom we communicated relevant messages for recommended practice about health, nutrition and child vaccination. Our project achieved a 26 percentage-point increase (increased from 62% at baseline in 2020 to 88% at endline in 2022) in age-appropriate child vaccinations by end of the project. We also conducted a cost-efficiency analysis by taking the actual costs incurred and project achievements into account. The key results from the cost-efficiency analysis revealed approximate cost for a fully immunized child as 21 US dollar, while per capita cost for communicating health messages to community members and health care worker training was 10 US dollar. UNICEF estimated approximately 32 US$ as vaccine delivery cost (=total cost - cost of vaccine and supply) per fully vaccinated child with standard schedule for children < 24 months which is higher than the cost for ensuring a fully immunized child in our project. These data clearly indicate the efficiency and success of community-based approach for strengthening MoH child immunization services in Kenyan rural and hard-to-reach communities. Key messages • Strong collaboration with Ministry of Health and community participation are critical key aspects for implementing child vaccination program successfully and cost-efficiently in rural communities. • Facilitating Ministry of Health for health system strengthening focus yields sustainable impact as footprint after end of a short-term of a community based project in developing country settings.


Often the best mutually exclusive alternative in a before-tax economy study is an inferior course of action in an after-tax study. Hence, we teach our students to include the effects of income taxes to avoid mis-allocating scarce capital. Despite this, our students who work in industry frequently perform only before-tax profitability studies and, as appropriate, leave the income tax intricacies to finance/accounting people. The purpose of this paper is to reinforce the necessity of after-tax economy studies in practice. An example is presented that illustrates four methods for taking income taxes into account. Two of the methods produce the correct rank ordering of projects while the remaining two do not. We recommend that an income tax specialist be consulted in practice when the projects under consideration are complicated with respect to their tax ramifications.


The orthogonality properties of the modes of a magnetoplasma waveguide involve a set of adjoint modes. We show how to obtain these adjoint modes without calculus in some particular cases.

A reverse phase ion_pair HPLC assay has been developed for screening glycinebetaine content in plant tissues in studies of its relation to salinity tolerance. Separation was performed on a 250 mm×4.6 mm stainless steel column (packed with 10 μm irregular_H) eluted with 50 mmol/L KH 2PO 4 (pH 4.45) containing ion_pair agent 0.1% PIC B_8 (1_octane sulfonic acid, Waters). Detection was performed by UV absorbance at 192 nm. The recovery rate of glycinebetaine in tissue extracts ranged from 85% to 96%. Glycinebetaine concentrations in leaf and root of Populus euphratica and P. `popularis 35_44' varied between 0.06 and 0.75 μg/g fresh weight (FW) with higher values in leaf tissue. Glycinebetaine level in suspension cells of P. euphratica increased from 0.45 to 0.77 μg/g FW following NaCl stress. The main assay procedure described here offers a number of advantages over other methods of estimating betaines: a) It increases precision and accuracy as compared with the periodide. b) Using a reverse HPLC column thus it decreases the expense for purchasing special equipment (such as strong cation_exchange columns). c) It avoids the need to generate derivatives thus allows rapid assay for betaines. This technique is not, however, suitable for use on crude, unpurified extracts and an ion_exchange clean up procedure is required. In the author's experiment, the extracts were passed through a 5 mL column of Dowex 1×8 (100-200 mesh, OH - form, Sigma) in series with a second column of a 5 mL Dowex 50W×2 (50-100 mesh, H + form, Serva). Bound betaine was recovered from Dowex 50W×2 with 10 mL of 2 mol/L NH 4OH and the eluate was evaporated to dryness at 65 ℃ in vacuum. 1 mL solution for the HPLC elution was used for dissolving betaine samples before separation on column.

Compared with teaching mother tongue and teaching foreign languages,there are both similarities and differences in teaching vocabulary of a second minority language.Similarly,they all can be divided into elementary,intermediate and advanced three stages,while at each stage,they have different objectives and tasks in teaching.In teaching a second minority language,integrating culture into vocabulary teaching will help students better understand both vocabulary and different cultures.This is the task of vocabulary learning after the intermediate stage.


We give an algorithm to find a mincut in an n-vertex, m-edge weighted directed graph using Õ( √ n) calls to any maxflow subroutine. Using state of the art maxflow algorithms, this yields a directed mincut algorithm that runs in Õ(m √ n+ n) time. This improves on the 30 year old bound of Õ(mn) obtained by Hao and Orlin for this problem. ar X iv :2 10 4. 07 89 8v 1 [ cs .D S] 1 6 A pr 2 02 1


Mineral property evaluation has such vast dimensions that it is almost impossible to adequately survey in one book. This task becomes considerably more difficult if one is to cover mineral property evaluation by choosing the most noteworthy of benchmark papers from the more than 30,000 titles on the subject. Although it probably is most closely related to geology and engineering, economic evaluation of mineral property in the loose sense bears directly on the disciplines of mathematics, risk analysis, chemistry, physics, geophysics, biology, ecology, surveying, management, finance, marketing, accounting, real estate, mineralogy, petrology, stratigraphy, electronics, computer technology, cybernetics, law, taxation, government, conservation, planning, transportation, and even aesthetics and philosophy. In the broad sense it is difficult to define what is not included in mineral property evaluation; practically every phase of such fields as mining engineering, mineralogy, and geology has at least an indirect bearing on the subject.


We propose a new flow for hardware/software co-design, based on the platform-based design, which forms a base for further automation attempts of the co-design process. We prove the applicability of the proposed flow on co-designing generic systems as well as RTOS-based systems. Our proposed flow starts with a software-only solution in which all system functionality is described as embedded software targeting a selected platform. Then, the flow iterates through co-verification, profiling, partitioning, and co-synthesis until the design criteria are met. We present four test cases to show the effectiveness of our proposed methodology. The main contribution added by the proposed methodology is incorporating the target application platform at the first stage of the flow then applying our iterative co-design algorithm without altering the main platform. This opposes other co-design methodologies that let the platform details be synthesized at later stages, widening the exploration space to be unrealistic and producing platforms that may vary to a large extent compared to the pre-verified application platform. The other contribution is the study provided on the effect of co-design on the behavior of RTOS-based platforms, which brings the flow closer to real-case problems, where most embedded systems utilize RTOS in their software stack.


The newly developed long-acting somatostatin analogue SMS 201 —995 has great significance in the therapy of various endocrine diseases and hormone secreting tumours (O'Donnel and Farthing 1989). Although the renal effect of native cyclic somatostatin was demonstrated earlier (Vora, Owens, Ryder, Atiea, Luzio and Hayes 1986), there is no data available regarding the influence of the long-acting somatostatin analogue on renal function. This question is of great importance since some differences exist between the two compounds in terms of their ability to inhibit various endocrine systems (Pless, Bauer, Briner, Doepfner, Marbach, Maurer, Petcher, Reubi and Vorderscher 1986). The purpose of this study was to investigate the possible influence of somatostatin analogue on kidney function in normal subjects.


This paper presents a high gain horn antenna with high aperture efficiency. The proposed horn consists of a waveguide coaxial adapter, 1-to-4 rectangular waveguide feed network, and 4 square horn units. This square horn unit is composed of five discontinuous sections, which can form a $3 \lambda\times 3\lambda \lambda$ is the wavelength at 3.0 GHz) uniform electric field distribution on the final rectangular horn face with basically same phase characteristics. Finally, a $2\times 2$ array, which is fed by 1-to-4 network, forms an aperture size of $6 \lambda\times 6 \lambda$. The optimized horn is fabricated and tested, and the measured results agree very well with the simulated results. At 3.0 GHz, the aperture efficiency is improved to 97.4% and this horn can generate good radiation patterns with nearly equal 3-dB beamwidth in both H- and E-planes.

Both the Nicomachean Ethics and the Eudemian Ethics discuss friendship (philia) in detail and both recognize several kinds of friendship: the association of morally good men, the association of pleasure seekers and the association of men seeking their own advantage. Furthermore, both ethical treatises are quite clear that this difference in kind is not to be explained in terms of simple, unmitigated equivocity. Friendships are not like capes which may be quite unrelated items such as garments and points of land extending into the sea. But how are the several kinds of friendship related? The Eudemian Ethics answers this question by introducing the focal analysis of pros hen equivocals whose application to being is familiar to students of the Metaphysics. What the Nicomachean Ethics does is not immediately clear. Many scholars, both ancient and modern, have seen focal analysis in the Nicomachean discussion.' This seems to me a mistake which merits correction. For properly understood the Nicomachean treatment of friendship is a complex and sophisticated analysis of considerable independent interest. Two distinct modes of analysis are discernible, yet neither is a focal analysis. In Section


From the time the students went out on the streets to petition and protest, Song sought various ways to enter their ranks by passing himself off as a student protestor. He was at the time quite reluctant to associate with people consistent with his own status—people who earlier in the movement were called "persons of unknown identity," and who later rallied together under the rubric of "citizens" (shi min) or as members of a "Workers Autonomous Federation." Prior to April 20, before the students started keeping strict watch over their own ranks, Song found a good many opportunities to join in their demonstrations.

Laser-induced thermochemical etching has been recognized as a new powerful method for processing a variety of materials, including metals, semiconductors, ceramics, insulators and polymers. This study presents characteristics of direct etching for Si substrate using focused argon ion laser beam in aqueous KOH and gas. In order to determine process conditions, we first theoretically investigated the temperature characteristics induced by a CW laser beam with a gaussian intensity distribution on a silicon surface. Major process parameters are laser beam power, beam scan speed and reaction material. We have achieved a very high etch rate up to and a high aspect ratio of about 6. Potential applications of this laser beam etching include prototyping of micro-structures of MEMS(micro electro mechanical systems), repair of devices, and isolation of opto-electric devices.


The invention relates to a method for manufacturing a magnetic object, in particular to an iron-silicon alloy magnetic powder core with the permeability mu of 50 and a manufacturing method thereof. The iron-silicon alloy magnetic powder core with the permeability mu of 50 is formed by pressing the following components: iron-silicon powder which comprises 2 to 8 weight percent of Si and the balance of Fe, phosphoric acid which is used for treating the surface of the iron-silicon powder and is 1.8 to 2.2 percent based on the weight of the iron-silicon alloy powder, and a phenolic resin which is 0.5 to 0.8 percent based on the weight of the iron-silicon alloy powder. The invention has the advantages that: 1, the manufacturing process is simple, and used equipment is simple; 2, the iron-silicon powder with low cost is adopted, so the production cost is greatly reduced; 3, the product manufactured by the method has high inductance, higher quality factor and a lower power loss value; and 4, the iron-silicon alloy can still maintain excellent soft magnetic performance at high temperature.


Children admitted to intensive care units as out-of-hours emergencies in England and Wales were no more likely to die than those who arrived during normal working hours, a study has found.

The study looked at 86 000 admissions to 29 paediatric intensive care units in England and Wales between 2006 and 2011.

The findings, published in the Journal of Pediatrics , showed that nearly half the children were admitted to intensive care units outside of working hours(40 948 (47%)). Risk adjusted mortality was no higher for those children admitted in the evenings and weekends than during the week (odds ratio 1.1, P=0.013). …


Karyotype studies were performed in four Astragalus species of A. cornu-carpae, A. mucronifolius, A. talimansurensis from the section Leucocersis and A. crysostachys from the section Hymenostegis. All four species showed 2n = 2x = 16 chromosome number and had metacentric and sub-metacentric chromosomes. The size of chromosomes varied from 0.75 μm in A. talimansurensis to 4.00 μm in A. cornu-carpae. The species studied differed significantly in the size of their chromosomes and in karyotype formulae indicating the role of quantitative change in the chromatin (DNA) material as well as chromosomes structural changes in the species diversification. The chromosome numbers of all four species studied are new to science. PCA ordination of the species showed their karyotype distinctness and that such data are of no use in the sectional delimitation in Astragalus.


This paper summarizes what was discussed in a lecture at the IXth International Conference on Porphyrin Chemistry held in Suzdal (Russia) in September 2003. The development of porphyrin chemistry in former Soviet Union countries and over the world are discussed. Some ideas which were cultivated during three conditional porphyrin periods (1930-1960, 1960-1980 and 1980-2000) are also discussed.
