Objective
To summarize the clinical characteristics, diagnosis, treatment and prognosis of EBV related post-transplantation lymphoproliferative diseases (PTLD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).

Methods
The clinical data of 262 cases of allo-HSCT were retrospectively, and EBV-associated PTLD occurred in 9 cases after transplantation with a incidence of 3.44% (9/262). Of the 9 patients, 6 were males and 3 were females, with a median age of 19 years; the primary disease was severe aplastic anemia (SAA) in 6 cases, acute myeloid leukemia in 2 cases and chronic myeloid leukemia in 1 case.

Results
The occurring median time of EBV associated PTLDs was 58 d (44-271 d). The clinical manifestations of most PTLD recipients were recurrent fever with no reaction to any antibiotics, antiadoncus and lymphadenectasis. Of the 9 recipients, 6 cases obtained pathological diagnosis, and 3 cases clinical diagnosis. Superficial lymph node and central nervous system (CNS) involved in 8 and 4 recipients, respectively; lung and bone involvement occurred in 2 recipients and 1 case, respectively. The median number of peripheral blood EBV DNA in 9 recipients was 7.21×104 copies/ml (6.37×103-4.56×105 copies/ml) at the time of onset. EBV DNA in peripheral blood was positive in only one case of 4 CNS recipients. Among 9 recipients after therapy, 4 cases were cured and 4 cases were partially effective, and 1 recipient was ineffective. After follow-up for 28 months (2-48 months), 6 cases died, and 3 survived.

Conclusion
Incidence of EBV related PTLD in SAA patients undergoing allo-HSCT is relatively higher than leukemia recipients. Reduction or withdrawal of immunosuppressant, Rituximab and low dose of DLI is effective treatment.

In this contribution we evaluate the impact of filtering techniques in enhancing the accuracy of forecasts of optical turbulence and atmospheric parameters critical for ground-based telescopes. These techniques make use of the data continuously provided by the telescope sensors and instruments to improve the performances of real-time forecasts which have an impact on the telescope operation. In previous works we have already shown how a mesoscale high-frequency forecast (Meso-NH and Astro-Meso-Nh models can produce reliable predictions of different atmospheric parameters and the optical turbulence. The mesoscale forecast has an advantage on the global model in having a better implementation of the physical atmospheric processes, including turbulence, and produces an output with greater spatial resolution (up to 100m or beyond). Filtering techniques that make use of the real-time sensor data at the telescope may help in removing potential biases and trends which have an impact on short term mesoscale forecast and, as a consequence, may increase the accuracy of the final output. Given the complexity and cost of present and future top-class telescope installations, each improvement of forecasts of future observing conditions will definitely help in better allocating observing time, especially in queue-mode operation, and will definitely benefit the scientific community in medium-long term.


Since December 2019, coronavirus disease 2019 (COVID-19) cases have been reported. The clinical features of COVID-19 in children are different from those in adults including morbidity and mortality. Even in infants and children, the clinical features are different according to ages in some cases. The children are commonly coinfected to diverse respiratory viruses, and therefore physicians, who take care of infants and children infected with COVID-19, have to consider diverse clinical aspects in their patients infected with COVID-19. In this review, we have summarized the clinical features of COVID-19 in children.


Two methods of reducing subaperture interferograms to produce full aperture aberration coefficients now exist: the Kwon-Thunen and the simultaneous fit method. The results of a numerical comparison show that for no flat-to-flat alignment the two work equally well and are equally sensitive to both higher-order noise and random noise. For ideal flat-to-flat alignment the Kwon-Thunen approach is less sensitive to noise by a factor of ~3. The simultaneous fit method requires fewer sample points and runs faster than the Kwon-Thunen method.


Non-orthogonal multiple access (NOMA) collaborative communication is extremely beneficial to the users with poor channel conditions. It is essential to examine the performance of different NOMA users with superior cooperative forwarding protocols. This paper addresses the user cooperative NOMA system where one strong user (U2) assists one weak user (U1) to forward messages, and investigates the outage performance of both users with hybrid decode-and-amplify forwarding (HDAF) protocol. First, we derive the outage probability of U2 and U1 with HDAF. Secondly, we provide the closed-form expression for outage probability of U1 with the incremental hybrid decode-and-amplify forward (IHDAF) protocol at U2, which can further enhance the outage performance of U1 compared with HDAF. Moreover, we also present the system throughput expression and provide deep analysis on the effect of different forwarding protocols. Numerical results and Monte Carlo simulations jointly confirm the correctness of all the analytic derivations. In addition to saving the energy consumption of U2, IHDAF can make U1 achieve superior outage performance to HDAF. However, the system throughput almost overlap for both schemes given a threshold rate pair.


This paper explores the impact that Smartphones have on the way modern supply chains operate, examining how the mobility they offer can completely alter the way users communicate, do business, interact, plan and most importantly think. A preliminary survey was conducted amongst Australian business users of Smartphones, which aimed to identify the type of user they were, what role and industry they were from, and what impact Smartphones had on their working behaviour. Results from this study gave rise to the theory that Smartphone functionality can be split into four distinct categories – Get, Give, Store and Share. In order to test this theory further a programme of industry interviews were organised that ventured beyond the opinions of merely the user, by incorporating the opinions of the Australian network carriers, technology providers, and application developers to validate the survey findings.

I begin with my early years and the influences that shaped my outlook on life. The period I was in school constitutes the second phase and my university years the third. Upon graduation, I joined a local university as an assistant lecturer, began to play a public role as a political commentator, and embraced Islam as my religion of choice. This fourth phase merges into the fifth phase with the formation of a reform group committed to the transformation of Malaysian society. After 14 years at the helm of this group, I felt the time had come to focus upon the changing international order, and together with some friends established an organization called the Just World Trust, which has now evolved into the International Movement for a Just World (JUST). While still in the sixth phase of my journey, I moved into party politics and became the deputy president of an opposition political party. Because party politics was an altogether different experience from my NGO activism, I would regard this short period as a phase in itself, the seventh phase. The eighth and final phase, which brings us to the present, sees me trying to combine my international activism with a renewed commitment to certain national concerns. From each of the eight phases I shall draw some larger conclusions about activism and politics in Malaysia and in the international arena, as the case may be. The interplay between the individual actor and his or her social milieu will also be analyzed. The study, in other words, hopes to offer some insights into the trials and tribulations that a citizen in the Global South will have to encounter in the quest for a better society and a better world.


Th e rare observation of the syndrome of multiple endocrine neoplasia of the 1 type with the lesion of adrenal gland, thyroid, parathyroid and pancreatic glands has been presented. Th e features of clinical manifestations and problems in diagnosis are underlined.


In the present paper the wood genera Barakaroxylon Surange & Maithy (1962) and Indoxylon Surange and Maithy (1963) are merged on the basis that the central and the peripheral secretory canals, which distinguish these two genera, have been found in one and the same specimen. On the basis of priority, the genus Barakaroxylon has been retained.


A cationic benzoxazole compound used commercially as an optical brightener was found to have a selective bactericidal effect at low concentrations on a wide range of bacterial phytopathogens; many strains of Agrobacterium, Corynebacterium, Erwinia, Pseudomonas and Xanthomonas were tested. Known phytopathogenic species of Corynebacterium, Pseudomonas and Xanthomonas were rapidly killed, whereas saprophytic strains of Corynebacterium and Pseudomonas were resistant to 500 parts/106. The phytopathogenic Erwinia spp. were inhibited only by the higher concentrations of AN, and some saprophytic E. herbicola var. herbicola strains were slightly sensitive. The extent and nature of this selective bactericidal property is examined and discussed. Resistant mutant colonies were very rarely encountered. The results are of significance in that the recognition of such phytopathogens under laboratory conditions is made easier. The resistance of Ps. aeruginosa to the compound and its almost unique ability to utilize it as a sole carbon source offer a means of isolating this organism.


The major difficulty in modeling federal support is to combine the equalizing fiscal capacities of regions with building conditions and incentives for regional authorities to accumulate their economic (fiscal) potential. The paper analyses one of possible variants of such model where the attempt to harmonize these, generally speaking, contradictory targets was made. To imitate different variants of fiscal capacities in regions which reflect both the production scopes in regions and the horizontal and vertical tax flows, and to find the situations of equilibrium in one or another sense is a key idea of our model concept.


A new species of Chiloschista Lindl. from western Thailand is described and illustrated with a line drawing and photographs. It is compared with the sympatric C. parishii Seidenf., from which it differs in having larger flowers, which are 11–12 mm across versus 8–10 mm across for C. parishii. The new species also distinctly differs in having widely spreading rostellum lobes and a viscidium that is as broad as the length of the stipe, as opposed to downward directed rostellum lobes and a viscidium that is distinctly narrower than the length of the stipe for C. parishii. The same distinguishing features separate the new species from the similarly colored C. trudelii Seidenf., which has inward-directed rostellum lobes and a viscidium that is distinctly narrower than the length of the stipe. Key worDS: Epidendroideae, new Chiloschista, Thailand orchid flora, Vandeae Received 23 June 2020; accepted for publication 27 July 2020. First published online: 12 August 2020. Licensed under a Creative Commons Attribution-NonCommercial-No Derivs 3.0 Costa Rica License. Introduction. The orchid genus Chiloschista Lindl. was first described by John Lindley, who proposed to segregate Epidendrum usneoides D.Don from Nepal into a separate taxon (Lindley 1832). Over the years, almost 30 specific epithets were applied to Chiloschista, but currently about 10 (Chen & Wood 2009, Wood 2014), or 22 (Govaerts 2020) species are accepted, distributed from the Indian subcontinent through SE Asia to Australia. The most recent phylogenetic analysis conducted by Zou et al. (2015) using five DNA markers (ITS, matK, trnL-F, psbA-trnH, and atpI-H) revealed that Chiloschista is a monophyletic taxon related to the group composed of the Phalaenopsis clade, Thrixspermum clade, and Vanda clade of Aeridinae. In previous treatments, Chiloschista was classified in Sarcochilinae (Schlechter 1926), Aeridinae (Dressler 1993), or Phalaenopsidinae (Szlachetko 2003). Representatives of this genus are monopodial plants growing as epiphytic or lithophytic herbs. Plants usually appear only as a cluster of roots, which hide the distinctly abbreviated stem. Narrowly elliptic and acute leaves only appear during the rainy season and soon fall off at the arrival of the dry season. The roots are gray, green, brownish or purple, photosynthetic, flat to terete, and sometimes scabrid. Chiloschista plants produce ephemeral flowers with a more or less clawed lip, which is attached to the apex of the column foot and is 3-lobed, deeply saccate/ pouched, or spurred (Wood 2014). In May of 2009, an unknown Chiloschista was discovered growing epiphytically on Hevea brasiliensis (rubber tree) in western Thailand (Fig. 1). Because of its vulnerable position due to ongoing destructive human activities, a plant was collected and introduced to cultivation where it flowered in April the following year. The flowers superficially resemble the sympatric C. parishii Seidenf., but differ in being larger and of a warm yellow color, with only faint brown spots on the basal half of the sepals and petals (Fig. 2) , while the smaller C. parishii generally has distinct spots throughout the sepals and petals (Fig. 3; Seidenfaden 1988). A more careful examination and comparison of the column details reveal more distinct differences where the unknown species has widely spreading rostellum lobes and a distinctly broadened viscidium (Fig. 4, 8), in comparison with C. parishii, which has downward projected and more or less parallel rostellum lobes and a distinctly narrower viscidium (Fig. 5, 8). The widely spreading rostellum lobes and the broadened viscidium also distinguish the unknown species from the colorwise similar C. trudelii Seidenf., (Fig. 6) which has inward projecting rostellum lobes and a narrower viscidium (Fig. 7–8). The rather distinct difference in size between the unknown species described here and C. parishii is most easily observed when the various flower parts are placed next to each other on the same scale (Fig. 8). We have found no other Chiloschista species that color-wise or morphologically corresponds with the unknown species and we, therefore, conclude that it is new to science and is described here.


Here is an article which speaks for itself. It is not quite clear to us that the conclusions are as new as Messrs. Abram and Cooper claim, but the history of the seniority system is certainly a matter of interest and importance in American politics. POLITY does believe that this article sheds some light on a political institution which is so well known that we tend to take it for granted, and like the biblical prophets, we need more light.


A number of concepts of particle acceleration by laser fields have been proposed almost since the beginning of the laser evolution. The recent tremendous progress of ultraintense lasers has created new concepts of high energy particle generation and acceleration due to strong field interactions with matter. In a state of the art of ultra‐intense lasers, the highest laser intensities reach a TeV range in terms of the ponderomotive energy exerted on matter. In this paper, the laser‐driven particle acceleration concepts are reviewed on basic mechanism of strong field‐particle beam and plasma interactions. New concepts of super high energy particle acceleration mechanism based on super‐strong laser‐plasma interactions are presented.


Purpose: to analyze the temporal trend of cesarean deliveries and associated maternal factors in Brazil and its regions between 2000 and 2015.
 Methods: ecological times series studies using data from the Live Births Information System (SINASC), of Brazilian Health System. Data from Brazil and regions were analyzed. Participants were all live births registered in SINASC, from 2000 to 2015. Simple linear regression was used to investigate the temporal evolution of rates for the population as a whole and stratified by the variables of interest, p value <0.05. Project approved by Ethics Committee.
 Results: the proportion of cesarean deliveries in Brazil increased from 37.8% in 2000 to 55.5% in 2015 (MPV = 2.61%). There was an upward trend in all Brazilian regions and maternal factors (p<0,001). The Southeast, Center-West and South regions had the highest rates. As for the maternal factors, the highest rates of cesarean section were found among the 35-year-old or over age group (60.4%) in white women (57,8%), with 8 or more years of study (57.8%) and who had 7 or more prenatal consultations (57.6%).
 Conclusions: the trend of cesarean births was upward in the period studied in Brazil and Regions in the maternal factors associated with age, schooling and number of prenatal consultations. The findings reinforce the need for measures to reduce the high cesarean rates, because this type of delivery is related to higher morbidity and mortality of the maternal-fetal binomial.

Literary works become something which cannot be a part from the environment of the author. Simply, an author often produces a literary work as the expression of his/her imagination based on his/her environment. In the world of literature, there are three literary genres: poetry, prose (short story and novel), and drama. Furthermore, this research concentrates in analyzing the novel. The author of the novel which has been chosen as the object of analysis in this research is Jonathan Swift. This research totally identifies the appearances of grotesque on Jonathan Swift`s Gulliver`s Travels. The statements of this research are: How does Jonathan Swift represent the grotesque on Gulliver`s Travels? What is the purpose of grotesque usage on Jonathan Swift`s Gulliver`s Travels? Grotesque as an art and literary term means the expression of the estranged or alienated world. It has strong affinity with the physically abnormal.

In analyzing the subject of materials, this research uses the descriptive method by doing the library research or textual analysis to get the descriptive method by doing the library research or textual analysis to get the descriptive data. The research threats the work as a unity of thought in which the elements are interrelated. As the qualitative research, this research requires theoretical base and reasoning logic. In this case, this research takes the book of Philip Thomson`s Grotesque.

Then, this research finds that there are some grotesque`s elements, extravagance, disharmony, abnormality, comic and terrifying, spreads within all of four parts of Gulliver`s Travels. Here, Swift tends to represents this elements of grotesque throughout the characters in each individual parts of Gulliver`s Travels, and hence these characters look as the strange or abnormal characters physically or mentally. This research also finds that the purpose of the grotesque usage on Gulliver`s Travels is aggressiveness. This is cannot be a part with the satire of Swift to the colonialism of England in eighteenth century.

As the final conclusion, this research emphasizes the relation of grotesque, satire, and the background of author (Jonathan Swift) on Gulliver`s Travels.


We report on experimental observation of terahertz emission and detection in a double graphene layer heterostructure with two independently contacted graphene layers separated by a thin h-BN tunnel-barrier layer. The bias voltages/doping causes the inter-graphene-layer population inversion with the possibility of photon-assisted resonant-tunneling transitions between the conduction bands and valence bands of the two graphene layers. We demonstrate that this can enable the realization of devices such as resonant terahertz detectors and emitters.


The polysaccharides,named PAG,were extracted from disk abalone(Haliotis discus hannai)gonad by proteinase-hydrolysis coupled to alcohol extraction method.The PAG was composed of 31.77% of polysaccharide,6.1% of protein,6.79% of fat,25.78% of sulphate,6.42% of aminohexose,and 1.25% of aminogalactose.The antioxidant activities of PAG were tested in vitro by scavenging activity on ·OH,DPPH·,reducing power and anti-peroxidation of lipid.The results showed that PAG had notable scavenging activity on·OH,DPPH· reducing power and moderate anti-peroxidation power of lipid,with a certain dose-effect relationship.


Vehicle during rearward movement - a system and method for operating the trailer unit, at least one sensor (12L, 12R) to generate output information representing the relative position between the rear and the front of the trailer of the vehicle to use. Electronic processing unit (22), the measured amount with a reference value, from the comparison, the trailer is determined whether the deflection from the straight alignment of the vehicle. If the trailer (20) is not aligned in a line with the vehicle (10), the system is a steering system (28) of the vehicle, the trailer brake system or interfere with both. Sensor distance a sensor or a camera, the amount is distance or marker position. As a reference value for comparison, the method uses a stored value or previously measured values, or simultaneously measured values. The method is operated by a switch operated by the driver of the automatic or in vehicles.


Cryogenic Permanent Magnet Undulators (CPMU) are currently being developed in some Synchrotron Light Sources. Low temperature magnetization hysteresis curves cannot be obtained by a simple transformation of ambient temperature curves; this requires a specific simulation tool. A Monte-Carlo based Permanent Magnet Simulator has been developed at the ESRF. In this simulator, the magnets can be described as a set of several magnetic grains. The model inputs are physical parameters such as anisotropy constants, easy-axis distribution and coercive field. The orientations of magnetic moments are calculated for each grain according to an analytical model and optimization methods are used for fast computations. Magnetization versus external field curves is calculated in a few seconds. The result fits with low temperature NdFeB magnetization measurements. These curves have been efficiently used to obtain Radia material parameters for the CPMU design.


From late 2012, the African Union Mission in Somalia (AMISOM) had adopted a largely defensive posture, citing limited resources as the principal reason for this. However, increasing numbers of Al-Shabaab attacks both inside and outside Somalia have forced AMISOM and its partners to open a new phase in the war against the group. To that end, in November 2013 the UN Security Council called for AMISOM to be enhanced in several areas and in January 2014 the mission adopted a new Concept of Operations. These developments facilitated a new wave of offensive operations conducted in tandem with the Somali National Security Forces. Nevertheless, AMISOM still confronts some familiar – and fundamental – challenges in its efforts to stabilise Somalia.


The paper is devoted to the construction of road crossings on the territory of the Arctic shelf and the Extreme North (Far North), as well as on the Siberian and Far Eastern rivers in winter. That is going to contribute to reducing logistic costs from cargo shipping down the ice surface significantly. In this research, the authors examine ice-based composites, where thin-walled polyvinyl chloride pipes are placed in the middle of the sample cross-section as a reinforcer. Two types of pipes were tested: vent white and orange sewer (drain) ones. While doing several series of model experiments, the researchers find out that the load-bearing capacity of ice samples reinforced with these pipes show very much the same results. So it was decided to combine the averaged model experiments with these pipes into one concluding result. The mechanical characteristics of ice were figured out by crushing samples of ice prisms that are 60 cm long, with a cross-section size of 15x15 cm. The aim of the paper is to define the influence of thin-walled polyvinylchloride pipes on the plastic properties and load-bearing capacity of ice samples when they are being reinforced. The test results prove that when reinforced with a pipe, it is destructed more gradually, and the deformations before the destruction have greater values. However, the thin-walled SN2 and SN4 pipes add nothing to increasing load-bearing capacity, unlike the SN8 sample, which increased the load-bearing capacity by about 10%. Therefore, the reinforced mid-section of ice samples with thin-walled PVC pipes marginally increased the plasticity of the samples, without the marked increase in the load-bearing capacity.

Chlamydia trachomatis(CT) is a common pathogen of sexually transmitted diseases. CT infection may make HIV-1 easily be transmitted. CT infection to host can induce the host to establish protective autoimmune response, including humoral and cellular immunities. Cellular immunity, rather than antibody, plays dominant protective role in primary and secondary infections of chlamydia trachomatis. Of which, various cytokines, such as IFN-γ, TNF-α and interlukins and so on play very important roles and they participate in protective immune defense system, but at the same time they result in a series of immunopathological lessions.


This article has a nature of a record. It was inspired by the 200th anniversary of the birth of Stanisław Moniuszko, and its main goal is to reference selected celebratory poems created in the 19th century in order to commemorate the composer. The author of this article indicated how different authors interpreted the ideological expressions of Moniuszko's music, its sources, and the functions it fulfilled. She also discussed the directions of the evolution regarding how the composer was depicted in poetry, as he was initially perceived as a "native busker", a Vilnius lyrnik, and a compatriot, and he gradually gained the rank of a folk minstrel and a prophet able to reproduce the "lyrical genius of the nation".


This paper describes spoken term detection (STD) with false detection control. Our STD method uses phoneme transition network (PTN) derived by multiple automatic speech recognizers (ASRs) as an index. An PTN is almost the same to a sub-word based confusion network (CN), which is derived from an output of an ASR. The PTN-based index we proposed is made of the outputs of multiple ASRs, which is known to be robust to certain recognition errors and the out-of-vocabulary problem. Our PTN was very effective at detecting query terms. However, the PTN generates a lot of false detections especially for short query terms. Therefore, we applied two false detection control parameters to the Dynamic Time Warping-based term detection engine. In addition, we changed the search parameters depending on length of a query term. Finally, the STD performance was better (0.785 of F-measure) than without any parameters (0.717).


This thesis addresses an innovative issue in Brazil: the discharge of children and adolescents with intestinal failure (IF) on parenteral nutrition (PN). Taurolidine lock has increasingly been used in patients on home PN to prevent catheter-related bloodstream infection (CRBSI), nevertheless, well-designed studies demonstrating its effectiveness are scarce. The objective was to compare the catheter lock therapy with taurolidine and heparin to prevent CRBSI in children and adolescents with IF on hospital PN and home PN. It was an open-label randomized trial with patients aged 1 month to 18 years from July 2014 to January 2017. Inclusion criteria were: a) patients on PN by tunneled central venous catheter (CVC) for at least 4 weeks; b) on cyclic PN for at least 1 hour. Exclusion criteria were acquired or primary immunodeficiency or diseases requiring recurrent use of antibiotics. All patients were randomly assigned to one of 2 groups: taurolidine lock+citrate 4% (group A) and heparin lock 50 UI/ml (group B). Patients were assessed for CRBSIs/1,000 catheter-days. Twenty-eight patients participated in the study (14 in group A, and 14 in group B). Overall median age was 7 (1-180) months, 21 boys. CRBSI rate during the hospitalization period was 7.1/1000 catheter-days on taurolidine lock and 7.9/1000 catheter-days on heparin lock, with no significant difference between them, P = 0.885, RR: 0.9012 (95% CI: 0.440 to 1.831). CRBSI rate during home PN period was 0.9/1000 catheter-days on taurolidine and 2.6/1000 catheter-days on heparin, with no significant difference between them, P = 0.444, RR: 0.3757 (95% CI: 0.034 to 2.622). There was no significant difference among taurolidine and heparin groups in either hospital PN and home PN periods (P = 0.932). In conclusion, taurolidine lock is safe in the setting of pediatric patients. Taurolidine and heparin lock were not significantly different to reduce CRBSIs in children and adolescents on hospital PN and home PN. Descriptors: Child. Adolescents. Parenteral Nutrition. Catheter-Related Infections. Heparin.

One-electron reduction of phenosafranine (PS+ 3,7-diamino-5-phenylphenazinium chloride), a phenazinium dye, has been studied in homogeneous aqueous and sodium dodecyl sulfate (SDS) micellar media, using the pulse radiolysis technique. The various reducing radicals employed for the study in homogeneous aqueous medium were eaq−, H˙, CO2,˙−, and isopropyl ketyl radicals (CH3)2˙COH. Semireduced species generated by these reactions have been characterized by their absorption spectra, decay kinetics, and pKa. The one-electron reduction potential of PS+ was determined at pH 7 in homogeneous aqueous solution employing nitrobenzene (NB/NB˙−) as the standard couple. One-electron reduction in SDS micellar medium and a detailed spectrophotometric investigation of the parent dye in this surfactant system was carried out in order to understand the dye–surfactant interactions in the micellar and premicellar media.© 2001 John Wiley & Sons, Inc.

The third part reports the results of analyses designed to reconcile our results with a prior empirical study on a closely related issue. The last part provides evidence that the Russell 1000/2000 reconstitution serves as a valid exogenous shock to stock liquidity.


Blowfish algorithm is a block cipher algorithm, its strong, simple algorithm used to encrypt data in block of size 64-bit. Key and S-box generation process in this algorithm require time and memory space the reasons that make this algorithm not convenient to be used in smart card or application requires changing secret key frequently. In this paper a new key and S-box generation process was developed based on Self Synchronization Stream Cipher (SSS) algorithm where the key generation process for this algorithm was modified to be used with the blowfish algorithm. Test result shows that the generation process requires relatively slow time and reasonably low memory requirement and this enhance the algorithm and gave it the possibility for different usage.

-conforming finite element spaces and show the discrete spaces satisfy local exactness properties. A feature of the spaces is their low polynomial degree and lack of extrinsic supersmoothness at subsimplices of the mesh. In the lowest order case, the last two spaces in the sequence consist of piecewise linear and piecewise constant spaces, and are suitable for the discretization of the (Navier-)Stokes equation.

Stemflow was evaluated in a water balance and its contribution to groundwater recharge determined. Gross precipitation, throughfall and stemflow were measured for one year in a pine forest (Tsukuba, Japan) to determine each component of the water balance in the forest. Groundwater recharge rates by stemflow and throughfall were calculated from a mass balance method using chloride in subsurface waters. The stemflow in the water balance was relatively small when estimated as a value per canopy projected area of the tree in the forest. However, the results for the mass balance of chloride in subsurface waters indicated that it was impossible to disregard the stemflow in determining groundwater recharge. Although the ratio of stemflow to the net precipitation was small in the water balance, the effect of stemflow on groundwater recharge was relatively large.


Distributed Denial of Service (DDoS) attacks is the most challenging problems for network security. The attacker uses large number of compromised hosts to launch attack on victim. Various DDoS defense mechanisms aim at detecting and preventing the attack traffic. Source IP address spoofing is one of the most common ways of launching Distributed Denial of Service attacks. In these types of attacks, attack packet's true origin is difficult to identify. Thus, it is very challenging to detect attack packets and handle defense mechanisms against such attacks. In this paper, defense mechanism uses cryptographic technique for identifying attack packets with source IP address spoofing and dropping those attack packets. This mechanism does not require restrictions or changes to internet routing protocols and is easy to deploy. The algorithm is efficient in identifying spoof attack packets and its effectiveness is evaluated by simulation experiments in NS3.


The main purpose of this research is portfolio optimization in Tehran securities exchange using the black hole algorithm and the Gravitational Research algorithm. We also propose an algorithm named Hybrid Algorithm which combines the two algorithms above to cover the weaknesses of these two algorithms. Finally we compare the results with the Markowitz model and choose the optimal algorithm. In order to analyze the data that is the same information extracted from the TSE Client software and RahAvard Novin Software, MATLAB software version of 2016and GAMS and SPSS have been used. This research is fulfilled in the period from 2011 to 2016. The method used in this study is based on the purpose of the applied research and based on the way of data collection as a descriptive research and correlation type, which is noticed with the retrospective and post-event approach and through the analysis of the observed information, attempts to optimize the portfolio using a black hole algorithm. In all the years of research, the hybrid method introduced in this research has obtained the nearest solution to the exact solution, which is the same Markowitz. In order to optimize the portfolio, black hole meta-heuristic algorithms, Gravitational Research and hybrid algorithm (hybrid) can be used instead of the Markowitz algorithm with higher accuracy and speed. The results of the present case study and other studies show that black hole algorithms, Gravitational Research, and hybrid algorithms are very quick in solving portfolio optimization problems

Teachers are the most critical factor in students' learning among all school-level aspects. Many countries including the United Arab Emirates (UAE) introduced licensure systems to ensure that the teaching profession as well as other educational professions are governed by professional standards and practitioners of education are meeting these standards. In this paper, we address the Educational Professions Licensure system implemented by the Ministry of Education (MOE) in the UAE in terms of its design, components, implementation tools, processes, and challenges. This paper highlights the foundations of the licensure system along with the procedure of licensing education professionals and it demonstrates the implementation of education licensure national tests. In addition, it explains the challenges of introducing the licensure system along with the future plans.

The problem of hydromagnetic free convection flow over a moving infinite vertical plate with Newtonian heating, mass diffusion and chemical reaction in the presence of a heat source is completely solved. Radiative and porous effects are not taken into consideration but they can be immediately included by a simple rescaling of Prandtl number and magnetic parameter. Exact general solutions for the dimensionless velocity and concentration fields and the corresponding Sherwood number and skin friction coefficient are determined under integral form in terms of error function or complementary error function of Gauss. They satisfy all imposed initial and boundary conditions and can generate exact solutions for any problem with technical relevance of this type. As an interesting completion, uncommon in the literature, the differential equations which describe the thermal, concentration and momentum boundary layer, as well as the exact expressions for the thicknesses of thermal, concentration or velocity boundary layers were determined. Numerical results have shown that the thermal boundary layer thickness decreases for increasing values of Prandtl number and the concentration boundary layer thickness is decreasing with Schmidt number. Finally, for illustration, three special cases are considered and the influence of physical parameters on some fundamental motions is graphically underlined and discussed. The required time to reach the flow according with post-transient solution (the steady-state), for cosine/sine oscillating concentrations on the boundary is graphically determined. It is found that, the presence of destructive chemical reaction improves this time for increasing values of chemical reaction parameter.


Unlike pulse width modulation (PWM) based approaches, the spectra of classical finite control set model predictive control techniques spreads uniformly across a wide frequency range for power converters, which makes the design of their filters particularly difficult. An effective method to achieve spectra similar to those of PWM for two-level power converters is the so-called model predictive period control (MPPC) approach, which makes the frequency of the converter's output voltage quasi-fixed by adding a constraint on the switching frequency. In terms of output voltage change, voltage-state-change (VSC) is more relevant than switch-state-change (SSC) because the output voltage change is unequal to that of SSC for multi-level power converters. In this work we propose two different control techniques, namely, switch-state-change (SSC-MPPC) and voltage-state-change based model predictive period control (VSC-MPPC), for 3L-NPC power converters. Simulation data confirm that, i) both approaches achieve current spectra similar to those of PWM-based solutions, ii) both of them achieve quasi-fixed switch frequency, which simplifies the heat sink design, however, VSC-MPPC practically operates with half of the reference frequency for 3L-NPC converter, iii) SSC-MPPC outperforms the VSC-MPPC approach in terms of power quality and neutral point voltage regulation but consumes much more switching losses especially for high level power systems.


The bis-arene cluster complex [Ru6C(CO)11(η6-C6H3Me3-1,3,5)2]1 has been synthesised and characterized by single-crystal X-ray diffraction; it possesses a unique structure in which the octahedral cluster core is sandwiched between the two arenes.


The mixed state of intermetallic superconductor YNi2B2C, like that of high-T, materials, is found to be separated into vortex solid and vortex liquid phases due to its large fluctuations. In addition, the vortex solid phase changes from a vortex lattice at low fields to a vortex glass at high fields. A very sharp resistive transition with a kink and an S-shaped I - V curve are observed in the vortex lattice transition region, H ≤ 1 T. At high fields, H ≥ 2 T, a scaling law holds for the vortex glass transition in R -- T and I - V curves, with field-independent critical exponents, v = 1.23 f 0.02 and z = 5.46 ± 0.32.


The present invention relates to a method for transcoding a N bits word into an M-bit word as N> M. The present invention is different areas, and more specifically applicable in the display field. The present invention has the following steps: · N decomposes the bit word in exponent and mantissa has a size exponent and mantissa varies according to the value of said N bits word, the size of the mantissa wherein N is increasing with the value of bit words, encoding the exponent part of-the N bits word into a variable number of bits a, such that a + B = M by removing several bits of the least significant if necessary mantissa obtaining a mantissa with a variable number of bits B.


This paper studies the effect of variable viscosity on the
transient Couette flow of dusty fluid with heat transfer between
parallel plates. The fluid is acted upon by a constant pressure
gradient and an external uniform magnetic field is applied
perpendicular to the plates. The parallel plates are assumed to be
porous and subjected to a uniform suction from above and injection
from below. The upper plate is moving with a uniform velocity
while the lower is kept stationary. The governing nonlinear
partial differential equations are solved numerically and some
important effects for the variable viscosity and the uniform
magnetic field on the transient flow and heat transfer of both the
fluid and dust particles are indicated.


The reaction 3He+3He→6Be*+γ was observed at 90° for bombarding energies between 0.86 and 11.8 MeV. The total cross section for transitions to the first excited state of 6Be varies smoothly from 0.4 to 9.3 μb (assuming isotropy). No γ-ray transitions to the ground state of 6Be were observed with an upper limit of approximately 10-2 μb at 1.4 MeV. Because of these low cross sections, this reaction is of negligible astrophysical importance compared to the 3He(3He, 2p)4He reaction.


This paper attempts to review the experiences of the Japanese soldiers who stayed in Jejudo during the end of the Pacific War. Three former Japanese soldiers - Kobayashi, Kamiki, Nakahara - are my considerations. I did oral testimonies for Kobayashi and Kamiki, and I used Nakahara's writings. I also used oral history and literature as the documents which recorded the experiences of the individual in this paper. Among their experiences, I am especially concerned about how three experiences - military equipment and tendency of them, the relationship between them and Koreans, the end of a war - differently appeared to them. It is said that the soldiers of the unit which Kobayashi belonged to were old and they were not well in training. But, the units which Kamiki and Kobayashi belonged to were in field training. Kobayashi and Kamiki said that the Korean soldiers in their units were good relationship with villagers in Jejudo, but, Nakahara wrote in his book that it was worthwhile to surveil the activities of the villagers after the end of the war. Their experiences are different each. We need to consider the variety of the experiences even under the situation which demands collective behavior like war. But, this paper argues that in case of the Japanese Army, the unit of the company is important. The experience of the ordinary soldier was limited within the company, and it was the unit that recognized the personality which the company was attached the nickname. And, one thing that I want to argue is the difference between the subjects in this paper and until now, there are a lot of oral history in this field. Jejudo was not in such extreme situation because there was not actual battle during the Pacific War. Former Japanese soldiers have written a lot of their experiences let alone the common subjects for the oral history. But, since Jejudo did not become the battlefield, their experiences in Jejudo during the war were remarked in very short in Kobayashi and Nakahara's writings. We can find that the oral history is useful to review the experiences of the individuals not only under the extreme situation or experiences but also dubious situation or position.


Androgen insensitivity syndrome (AIS) is a condition that affects sexual development before birth and during puberty and is one of the more common disorders affecting masculinisation of the male genitalia. This rare syndrome (affecting 2–5 per 100,000 genetic males) is classified as complete (CAIS), partial (PAIS) or mild depending upon the extent of residual functional androgen receptors (AR) which in turn influence the phenotype. Mutations of AR have been reported in approximately 95% of persons with CAIS and in 10% with PAIS.1

Genital ambiguity is variable in PAIS with a frequent phenotype of micropenis, posterior hypospadias and cryptorchidism. PAIS has a higher risk of associated malignancy than in CAIS.2 Current evidence recommends the retention of cryptorchid testes through puberty for hormone production benefits, including bone and secondary sexual development.3

Mullerian duct derivatives (such as fallopian tubes, uterus, cervix and upper vagina) are usually absent in patients with AIS but the occasional presence in some raise the possibility of either defective production or response to Mullerian inhibitory factor (MIF).


Carbon quantum dots (CQDs) were prepared using one step hydrothermal method using ammonium citrate and lactose as nitrogen and carbon sources. The prepared CQDs were characterized using XRD, TEM, XPS, FT-IR, UV-Vis, and fluorescence spectroscopy. The fluorescence quantum yield of the CQDs is 17.6 %. The CQD fluorescence sensor based on the quenching effect by Cr (VI) was successfully developed for quantitative determination of Cr (VI). Moreover, CQDs exhibited a sensitive and selective response to Cr6+ compared to other common ions in water (Cu2+ , Ca2+, Zn2+, Fe2+ and Mg2+). The prepared CQD fluorescence probe demonstrates good linear detection performance in the concentration range of 0.10 ~ 0.60 mg/L for Cr (VI) ion. It is thus potentially feasible to detect industrial wastewater with discharge standard of less than 0.50 mg/L.


Words in a document that are frequently occurring but meaningless in terms of Information Retrieval (IR) are called stopwords. It is repeatedly claimed that stopwords do not contribute towards the context or information of the documents and they should be removed during indexing as well as before querying by an IR system. However, the use of a single fixed stopword list across different document collections could be detrimental to the retrieval effectiveness. This paper presents different methods in deriving a stopword list automatically for a given collection and evaluates the results using four different standard TREC collections. In particular, a new approach, called term-based random sampling, is introduced based on the Kullback-Leibler divergence measure. This approach determines how informative a term is and hence enables us to derive a stopword list automatically. This new approach is then compared to various classical approaches based on Zipf's law, which we used as our baselines here. Results show that the stopword lists derived by the methods inspired by Zipf's law are reliable but very expensive to carry out. On the other hand, the computational effort taken to derive the stopword lists using the new approach was minimal compared to the baseline approaches, while achieving a comparable performance. Finally, we show that a more effective stopword list can be obtained by merging the classical stopword list with the stopword lists generated by either the baselines or the new proposed approach.


In this paper, we first establish a rational iteration method which can be used as a root-finding algorithm for almost every polynomial. It has no nonrepelling extraneous fixed point in the complex plane and is generally convergent for both quadratic and cubic polynomials. Then some properties of this algorithm are given. By the aid of computer, we produce pictures of the Julia sets for the iterations of some polynomials. Numerical results show that it is a root-finding method with convergence order the same as Halley's method.


Many molecule‐based phylogenetic analyses find that the mammalian order Artiodactyla (even‐toed ungulates) is paraphyletic unless cetaceans (whales, dolphins, and porpoises) are nested within it, a hypothesis that runs contrary to traditional morphology‐based ideas. Here I present a total evidence analysis of this question based on 10 extant and 27 extinct taxa, using two character data partitions: (i) skeletal data and (ii) neontological data (soft morphology, retroposons, and DNA sequences [γ‐fibrinogen, β‐casein, and κ‐casein and mt cytochrome b]). A sensitivity analysis varying gap cost and transversion/transition ratio over nine parameters was implemented in the sequence alignment and in the parsimony analysis. The two data partitions are significantly incongruent, and the neontological data partition includes over six times as many characters as the osteological data partition. The osteological data partition, however, samples almost three times more taxa, taxa that cannot be sampled for neontological data because they are extinct. Osteological data resulted in artiodactyl monophyly, and neontological data resulted in artiodactyl paraphyly over all nine parameters. In the total evidence analysis the parameter most congruent with the overall character data is unresolved as to the sister taxon of Cetacea; however, the Adams consensus tree favors the neontological result. Extinction of almost 90% of the clade and particularly poor knowledge of stem taxa at the base of Artiodactyla make resolution of conflicting molecule‐ and morphology‐based phylogenetic signals particularly difficult.


In Chile in recent years, changes in precipitation and temperatures have been reported that could affect water resource management and planning. One way of facing these changes is studying and understanding the behavior of hydrological processes at a regional scale and their different temporal scales. Therefore, the objective of this study is to analyze the importance of the hydrological processes of the HBV model at different temporal scales and for different hydrological regimes. To this end, 88 watersheds located in south-central Chile were analyzed using time-varying sensitivity analysis at five different temporal scales (1 month, 3 months, 6 months, 1 year, and 5 years). The results show that the model detects the temporality of the most important hydrological processes. In watersheds with a pluvial regime, the greater the temporal scale, the greater the importance of soil water accumulation processes and the lower the importance of surface runoff processes. By contrast, in watersheds with a nival regime, at greater temporal scales, groundwater accumulation and release processes take on greater importance, and soil water release processes are less important.

Abstract The new chromous oxo-halides Cr 4 (Si 2 O 7 ) X 2 ( X = Cl, Br) which adopt a hitherto unknown structure type were obtained as small, deep blue crystals from mixtures of Cr 2 O 3 , Cr, SiO 2 , and CrCl 3 or CrBr 2 , respectively, in sealed silica tubes at elevated temperatures (Cr 4 (Si 2 O 7 )Cl 2 : 1000°C; Cr 4 (Si 2 O 7 )Br 2 : 1220°C) in the presence of a mineralizer (NH 4 Cl; excess of CrBr 2 ). They show remarkable stability against oxidation. The crystal structures of both Cr 4 (Si 2 O 7 )Cl 2 (Cr 4 (Si 2 O 7 )Br 2 ) have been determined and refined from X-ray single crystal data ( Pc No. 7), Z = 4, a = 6.3853(7) A (6.414(3) A), b = 12.707(2) A (12.829(6) A), c = 10.448(1) A (10.540(6) A), β = 92.37(1)° (91.61(4)°)). Four circle diffractometer data were used for the refinement of the chloride structure while imaging plate data were used for the bromide (conventional residual R 1 = 0.016 (0.053) for 4761 (3491) Fo > 4σ, 4945 (3911) independent reflections, 273 (273) parameters). The structure consists of eight crystallographically different Cr 2+ with c.n. five or six and mixed coordination by oxygen and halogen. All coordination polyhedra are highly distorted as a result of the Jahn–Teller effect. Two independent disilicate groups exhibit almost eclipsed conformation with bridging angles (Si–O–Si) of 145.8° and 138.4° for the chloride and 146.3° and 140.8° for the bromide.


Abstract This paper presents a generalized concept of combined hardening which is examined by experimental and computational methods. A 'kinematic displacement parameter', β, relating the movement of the yield function surface to the Bauschinger effect, is defined in terms of its dependence on material properties and loading state. Experimental relations between β and the plastic strain, εp, are prsented for three metals. The monotonic stress-strain and β data are used in a finite element program to show that settled cyclic hysteresis loops are soon established. Settled cyclic stress-strain curves computed in this way are in good agreement with the experimental results for an aluminium alloy, a stainless steel that shows cyclic hardening, and a titanium alloy that shows little cyclic effect.


Defining the phrase «welfare dependency» from a feminist perspective offers a way to understand how the rhetoric around the use of this phrase continues to legitimize current changes in Aid to Families with Dependent Children (AFDC) while simultaneously diverting the public's attention from the real issues of poverty of and discrimination against women. This article includes a detailed definition of welfare dependency, a brief history of its usage, and a reconceptualization of women's use of AFDC on a long-term basis. This reconceptualization expands on international dependency theory and reframes dependency as interdependency that builds on women's strengths, women's rights, and women's role in the public and private spheres. Specifically, it calls for a research and practice focus on understanding the daily lives of individuals and groups of women who receive AFDC on a long-term basis in an effort to understand women's strengths, situations, and needs

Magnetic field interactions with particles, as observed in magnetophoresis, are becoming important tool to understand the nature of the iron role in heme molecular complex, besides other useful applications. Accurate estimations of some macroscopic magnetic properties from quantum mechanical calculations, such as the magnetic susceptibility, can also check the reliability of the heme microscopic models. In this work we report, by using the Stoner criterion, a simple way to obtain the magnetic susceptibility of the heme complex from Density Functional Theory calculations. Some of our calculated structural properties and electronic structure show good agreement with both the available experimental and theoretical data, and the results show that its groundstate is a triplet 3A state. From the obtained results, we have evaluated the exchange interaction energy, J = 0.98 eV, the associated magnetic energy gain, ΔEM=−0.68 eV, and the magnetic susceptibility, χ0=1.73×10−6 cm3/mol for the heme alone (with uncompl...


Abstract : The procurement costs of military hardware have risen dramatically in recent years. Presently, there is a great deal of pressure exerted on military officials to control the rising procurement costs. One of the more promising techniques being used toward this end is known as 'Should Cost Analysis,' a cost analysis technique that provides an independent cost estimate for production contracts. Currently, the Army, the Navy, the Air Force, and the General Accounting Office (GAO) all conduct independent should cost analysis whenever they deem it appropriate to do so. The paper proposes that all future should cost studies be controlled and conducted by the GAO alone. The result should be a more cost-effective application of the should cost concept.

An expression for an upper limit of an absolute value of a method error of dead reckoning for a vessel's geodetic latitude has been derived. The error occurs due to simplification of a corresponding dead reckoning equation. The simplification of the equation is a conversion of an integrated function which depends on latitude and cannot be expressed as an elementary function to a function value at a minimum value of latitude. The expression for the upper limit is true when a geodetic height of a ship is constant during her motion. It does not take into account computational error and other method error resulting from integration of a northern velocity component as well. Dependencies of the upper limit have been analysed. The upper limit depends on a maximum absolute value of a northern speed; geodetic height; semi-major axis and eccentricity of an ellipsoid; a difference between maximum and minimum of an absolute value of latitude. It has been determined when the method error takes a maximum absolute value. Corresponding error calculations have been carried out for different speed modes and time of a vessel's sailing. A distinctive feature of the proposed method of solving of dead reckoning equation is, that it is possible to get the upper limit of the absolute value of the method error on the basis of a maximum absolute value of a ship's northern speed within a certain time interval and of its length. Being complemented with corresponding expressions for a geodetic longitude, proposed calculation methods may be used for testing of other dead reckoning algorithms.


The overhead costs of transit operations represent one area in which economies can be achieved. For a large system the costs of putting buses on routes and pulling them off (pull-on and pull-off) and driver relief can be substantial: up to 10 percent of the operating budget for the system studied. These costs are directly related to the route structure and the location and capacity of bus garages. This paper describes a procedure that uses generally available planning data in the analysis of the pull-on and pull-off and relief costs for alternative garage programs. Factors studied include the number of facilities, their location, their capacity, and the routes served from each garage. It is shown that the location of garages in relation to day-base routes is a determinant of relief costs and that the difference in operating costs for alternative programs can approach $1 million per year.

A model for Schottky barrier-like heterojunction photoelectrodes is presented. This model allows the calculation of the current-voltage curves for such electrodes under different conditions of illumination and electrochemical charge transfer. SnO2-coated n-type Si electrodes in contact with the redox systems K3/K4 Fe (CN)6 and Cl2Cl(-) show experimental photocurrent-voltage curves with the behavior predicted by the model. The effect of the charge transfer overvoltage and the expected current limitation due to photon control and/or redox ion diffusion are demonstrated. The feasibility of solar energy conversion through photoelectrolysis, by means of cells based on heterojunction photoelectrodes, is discussed.


Residential wood combustion emissions were analyzed to determine emission rates and to develop chemical emissions profiles that represent the appliances and woods typically used in wood-burning communities. Over 350 elements, inorganic compounds, and organic compounds were quantified. A range of 4−9 g/kg dry fuel of particulate matter (<2.5 μm) and 5−22 g/kg volatile organic compounds were observed. Samples were collected using a dilution stack sampler equipped with a 2.5-μm particle selective cyclone. Emissions were diluted 20−70 times, cooled to ambient temperature, and allowed 80 s for condensation prior to collection. Wood type, wood moisture, burn rate, and fuel load were varied for different experiments. Fine particle and semivolatile organic compounds were collected on filter/PUF/XAD/PUF cartridges. Inorganic samples and mass were collected on Teflon and quartz filters. Volatile organic carbon compounds were trapped with Tenax (C8−C20), canister (C2−C12), and 2,4-dinitrophenylhydrazine impregnated ...

in disputes. It is noteworthy, indeed, that both sides of the bargaining table are aware of the common necessity of keeping production going. Yet work stoppage through lockouts or strikes has been quite frequent, perhaps more frequent than idealistic readers have cared to realize. Sweden does not offer any utopian formula. Even the intelligent national agreements cannot be said to be any final solutions of the apparently inevitable problems in this ageless struggle. However, &dquo;during the past forty years-approximately the period in which collective bargaining has been carried on on a national scale-Sweden has developed from a poor farming country into a well-to-do and progressive nation. From 1900 to 1930, per capita real [italics mine] income increased by somewhat more than 60 per cent. The volume of industrial production-i.e., the products of all factories-approximately trebled during this same interval, while the population grew by only 20 per cent.&dquo; The author is certainly justified in devoting a chapter to this question: &dquo;Will the Swedish Scheme of Bargaining Work in America?&dquo; It would serve no purpose to state his conclusions. The whole book must be read first. ERIK T. H. KJELLSTROM Rutgers University


Heparan sulfate (HS), a polysaccharide of the glycosaminoglycan family characterized by a unique level of complexity, has emerged as a key regulator of many fundamental biological processes. Although it has become clear that this class of molecules exert their functions by interacting with proteins, the exact modes of interaction still remain largely unknown. Here we report the engineering of a (13)C-labeled HS-like oligosaccharide with a defined oligosaccharidic sequence that was used to investigate the structural determinants involved in protein/HS recognition by multidimensional NMR spectroscopy. Using the chemokine CXCL12α as a model system, we obtained experimental NMR data on both the oligosaccharide and the chemokine that was used to obtain a structural model of a protein/HS complex. This new approach provides a foundation for further investigations of protein/HS interactions and should find wide application.

The detection of brain tumors using image processing has recently emerged as a significant area of research. Despite numerous efforts, the development of an accurate brain tumor detection method remains a challenge. Machine learning techniques have been widely explored for this purpose, with deep learning models being a subset of particular interest. While various deep learning models such as GoogLeNet and CapsNet have been proposed, the use of pre- trained models such as ResNet18 has yet to be fully investigated. This study presents a deep learning approach utilizing ResNet18 for the detection of brain tumors in MRI images. The model was evaluated using a publicly available dataset obtained from Kaggle. Results of the experiments indicate that the model achieved an accuracy of 0.8833, sensitivity of 0.8667, specificity of 0.9000, and precision of 0.8966. Our findings demonstrate that this model outperforms previous deep learning models in terms of accuracy, specificity, and precision.

Venous thromboembolism (VTE) provoked by transient risk factors has traditionally been classified as a single entity with lower risk of recurrence. We evaluated the association between different categories of transient provoking factors and the relative risk of recurrence.


LCL-type grid-connected filter circuits are widely used for line network transmission because of their high ability to suppress current harmonics. However, due to the presence of resonance points in this third-order circuit, the system can generate severe oscillations. In order to improve power quality, a combined feed-forward factor control strategy is proposed in this paper. The control system introduces a combined feed-forward factor and incorporates the idea of dual PI control to ensure that the order of the system is reduced while improving its stability, followed by a detailed derivation of the constraint equations for each link parameter. The simulation verifies that the control scheme can regulate the output voltage of the line network and effectively reduce the harmonic content of the line network, providing a reference for reducing the harmonic content of grid-connected currents in engineering.

Methods: Patients, who presented to the emergency department and were admitted to the intensive care unit from January 2018 to August 2018, were reviewed retrospectively. The clinical features, inflammatory marker levels, such as C-reactive protein, lactate, simplified acute physiology score 3, length of stay, and in-hospital mortality were obtained from the medical records. Patients, who visited the emergency department because of trauma or suicidal attempts, arrived after out-hospital cardiac arrest, or were diagnosed with cerebrovascular disease, were excluded.
Results: Of the 310 patients included, 65 died during their admission, and 245 patients were discharged after treatment. The receiver operating characteristic curve showed that the delta neutrophil index (area under curve [AUC], 0.72), Creactive protein (AUC, 0.70), lactate (AUC, 0.64), and simplified acute physiology score 3 (AUC, 0.79) indicated a low predictive power for in-hospital mortality. Whole patients were divided into four subgroups (infectious diseases, cardiovascular diseases, gastrointestinal bleeding diseases, and others). The receiver operating curve of delta neutrophil index revealed infectious diseases (AUC, 0.65), in cardiovascular diseases (AUC, 0.70), and gastrointestinal bleeding diseases (AUC, 0.79).
Conclusion: The role of the delta neutrophil index for predicting the prognosis of in-hospital mortality showed equally low predictive power for critically ill patients with the C-reactive protein and lactate.


Background. Hyperbaric oxygen therapy (HBOT) increase endothelial oxygenation and stimulates vascular endothelial growth factor (VEGF) as the most specific and potent growth factor for angiogenesis, and increases wound healing process. The aim of the study is to know if five days HBOT can increase the level of VEGF in diabetic ulcer patients. Methods and results. Clinical experimental study was conducted on 12 diabetic ulcer patients who received HBOT 30 minutes, 3 times a day for 5 days (HBOT group) and 10 diabetic ulcer patients as a control group who did not receive HBOT (non-HBOT group). The VEGF level in both groups was measured on days 1 and 5. In HBOT group the mean level of VEGF on day 1 was 1241.325 + 237.6533 pg/ml and became 1244.458 + 264.5641 pg/ml (p = 0.583) on day 5, while in non-HBOT group the mean level of VEGF on day 1 was 1262.350 + 227.9603 pg/ml and became 1112.460 + 220.3795 pg/ml (p = 0.093) on day 5. There were no significant differentiation of VEGF level between HBOT group and non-HBOT group both on day 1 (p = 1) and day 5 (p = 0.872) Conclusions. Hyperbaric oxygen therapy for 5 days did not increase the VEGF level of diabetic ulcer patients


The use of direct expansion (DX) air conditioning (A/C) systems is widely seen in residential buildings in tropics and sub-tropics. However, most DX A/C systems are equipped with single-speed compressor and supply fan, relying on On—Off cycling as a low-cost approach to maintain only indoor dry-bulb temperature, whereas the indoor air humidity is not controlled directly. This also leads to potential inefficient energy use due to space over-cooling. This paper suggests a novel control strategy (termed Hi—Lo strategy) of using two-speed compressors in DX A/C systems for better indoor thermal environment control and higher energy efficiency. Experimental work has been carried out to test the Hi—Lo control strategy. Experimental results suggested that the novel control strategy can help improve the indoor humidity control without sacrificing energy efficiency. Practical application: The use of ON/OFF control at part load conditions in conventional DX A/C systems will lead to undesirable relative humidity levels. The problem is more prominent when the latent load is dominant. In order to have a better dehumidification effect, a lower indoor dry bulb temperature has been often set. On the other hand, the use of variable speed compressors in DX A/C systems can be a solution to the problem of humidity control, but its cost is comparatively high. The suggested novel control strategy is a low cost approach, which can save energy and provide a better indoor humidity control using DX A/C systems.


In the new historical period, making and consuming of the idol assumes a series of new characteristics, such as miscellaneousness, pan-secularism, intermediacy and sociality. This naturally has something to do with the current society and their psychology. Therefore, it is especially important that mass media should take the social responsibility of their own for their promotion plays an indispensable part in making and consuming of the idol.


Numerical computations are made for the nearshore currents and morphology around a system of multiple submerged groins. They function in decreasing the speed of longshore currents and controlling beach erosion. Nearshore currents are computed with the PEGBIS model by Goda (2004) for wave transformation and beach morphology is estimated with the suspended sediment transport model by Katayama and Goda (2000). The computation indicates the efficacy of a submerged groin system for beach erosion control.


Purpose: Growing level of automatism, information technologies and other technological achievements on the one hand and unadjusted production companies in Bosnia and Herzegovina on the other, impose a need for new knowledge from the aspect of adaptability and increasing eco-efficiency of production systems. Engineers face the problems of growing trends of change in the area of technology, organization, decision making process and management of production systems. Changes cause searching for new solutions, and solutions demand innovative action in changed conditions. New and innovated technologies, also wide appliance of recycle procedures of waste materials and their further use, will lead to appliance of new production principle "production-consumerwaste-recycle-entrance", which demands a need for new knowledge connected with relationship between production system and environment. For production systems, strategy of Cleaner Production is primarily applied to reducing pressure during whole cycle of production and services, from design and use to the final disposal. Design/methodology/approach: This work will show how dangerous and toxic waste can be controlled and reduced by using principles of "Cleaner Production", as well as how that task will be transferred to the lower level of managers, who should predict, plan, manage and control the market. Using control of quantity and quality of raw materials, parameters of workability and reduction of waste risk materials can be influenced. The factory producing tools planned and carried out an experiment with the purpose of substitution of the mineral oils for cutting. That experiment has been carried out by the mathematic apparatus "Box-Wilson" with the usage of two-factor plan of the experiment. Findings: Experiment showed that it is possible to use synthetic oils for cutting in certain intervals of work. Synthetic oils are biodegradable thus they have lesser pressure to the environment. Research limitations/implications: This work justifies possibilities of innovative action in the EMS functioning. Technologist can make plans, with permanent goal of achieving higher eco-efficiency only in the conditions of use that have been already explored. Practical implications: There are implications with the need of researching conditions, and with processing of increased demands for the quality. Every problem needs to be approached in a experimental way and confirm the assumption. Originality/value: This work is original in observed conditions of usage and with the usage of given approach in the research. It is confirmed that that synthetic oils for cuttings can be substituted by mineral oils and in that way increase eco-efficiency.


In Fukushima accident, when the severe accident such as a natural disaster happens, it is impossible to monitor the plant status due to a extreme environment and station blackout and most I&C systems break downs. Finally, these cause the loss of emergency cooling function and thus results in a hydrogen explosion and radiation leak. In this paper, the emergency response system is introduced that monitors and controls properly when the sever accidents like Fukushima accident happen, And the performance requirements of a wireless communication system used in the emergency respons system is described and the performance of emergency communication system is analyzed using the markov model


Purpose: Pain coping is important in health outcomes. In the current literature, pain coping usually means those goal-directed strategies to manage pain. The study goal was to explore what personal meaning "coping" has for work-disabled individuals in pain. Method: Qualitative, in depth interviews with follow-up verification interviews were conducted with 13 volunteers who were off work and in rehabilitation for chronic pain from a musculoskeletal injury. The two main questions were: (1) How did participants understand the term "coping with pain"; and (2) how did they come to this understanding of coping. The theoretical approach was social phenomenology and data were analyzed using thematic analysis. Results: The dominant theme was that pain coping is an intrinsic and life-defining attitude and belief. This understanding primarily arose through early modeling by parents and significant others. Secondary theme was that coping is practical strategies to manage or eliminate pain. This arose through more current interactions with health care providers and others in the social network. Conclusions: Researchers' and clinicians' view of coping may not always match the views held by individuals with chronic pain. This might impact on the effectiveness of interventions designed to modify coping behaviors, and alternative ways of intervening may be needed. Implications for Rehabilitation Coping has an important impact on health recovery after musculoskeletal injuries but interventions to modify pain coping strategies in those with chronic pain have met with modest success. The dominant model for coping in the research literature defines coping as a behavioral and/or cognitive response to a stressful situation. A qualitative study to examine what personal meaning "coping" holds for work-disabled persons with chronic pain suggests that coping is primarily conceptualized as an intrinsic and life-defining attitude/belief learned early in life. The above incongruence between the dominant research model of coping and the views of workers with chronic pain might impact on the effectiveness of interventions designed to modify coping behaviors for this population, and alternative ways of intervening may be needed.


Background. Young children are often required to carry out writing tasks in an educational context. However, little is known about the patterns of writing skills that children with Specific Language Impairment (CwSLI) have relative to their typically developing peers. Aims. The study aimed to assess the written language skills of CwSLI and compare these to typically developing peers. It also aimed to assess the relative contributions of reading and spelling skills to written language skills. Methods & Procedures. Forty-five children took part in the study, 15 were CwSLI, 15 were a chronological age match, and 15 were a spelling age match. The children took part in a range of tasks that assessed writing, reading, and spelling abilities. Outcomes & Results. In their written language and compared to typical age matched peers, CwSLI used a significantly less diverse range of words, had lower quality written compositions overall, and lower levels of organisation, unity and coherence. They also had a higher proportion of spelling errors. Overall, writing skills were strongly associated with reading skills. Conclusions & Implications. The findings demonstrate the challenges CwSLI have in producing good quality written text and that these challenges are likely to be related to the linguistic skills profile shown by these children. What is already known on this subject: Previous research has shown that children with specific language impairment have difficulties with a range of literacy skills. It is known writing to a good standard involves strong linguistic skills and that writing is an expected part of a child's educational experience in the United Kingdom. What this study adds: When compared to a group of children who were chronologically age matched and a group who were matched by spelling age, the findings showed that the children with specific language impairment (SLI) had lower quality written language overall. Moreover, the text analysis indicated that children with SLI had difficulty organising coherent texts. The findings also highlighted the positive association between reading and writing skills.


The ever-increasing need for accurate mathematical modelling of physical as well as artificial processes for simulation and control leads to models of high complexity. The complexity appears as high order describing dynamical system or complex nonlinear structure. This problem demands efficient computational prototyping tools to replace such complex models by approximate simpler models, which are capable of capturing dynamical behaviour and preserving essential properties of the complex one. Due to this fact model reduction methods have become increasingly popular over the last two decades. On the other hand, most of the methods that are proposed so far for control and analysis of hybrid and switched systems are suffering from high computational burden when dealing with large-scale dynamical systems. Because of the weakness of nonlinear model reduction techniques and due to pressing needs for efficient analysis and control of large-scale dynamical hybrid and switched systems; it is essential to study model reduction of hybrid and switched systems in particular. This fact has motivated the researchers in hybrid systems to study model reduction. To the best of our knowledge just few research works on model reduction of hybrid systems have been reported in the literature [1]-[4]. Therefore this problem is still largely open. We will start the talk with giving a brief walk-trough the previous methods, their advantages and disadvantages concerning computations and conservatism and also from system and control theoretic technical viewpoint. We will proceed with the classification of hybrid and switched systems and we will mainly concentrate on switched systems with autonomous switching and state-based switched systems.The generalized gramian framework for model reduction of switched systems with autonomous switches will be presented then. This framework is based on the generalized gramians instead of gramians [5]. In order to compute the generalized gramians , one should solve Lyapunov inequalities instead of Lyapunov equations. This method is used to devise a technique for structure preserving model reduction methods in [6].We first show that the generalized method in [5] can be extended to various gramian based reduction methods. We have modified the original method in [5] to avoid numerical instability and to achieve more numerical efficiency by building Petrov-Galerkin projection


Respiration dysfunction is a major cause of morbidity and mortality in spinal cord injury(SCI).Serotonin can improve abnormal respiration after different spinal cord injury.Serotonin can promote remodeling of respiration function by cross phrenic pathway and phrenic nerve after C2 spinal cord hemisection.And serotonin can promote remodeling of respiration function by long-term facilitation after cervical dorsal rhizotomy.Serotonin can ameliorate respiratory deficits resulting from spinal cord hemicontusion through a dorsal horn afferent-supraspinal respiratory center pathway.


Learning to write formal mathematical proofs presents a major challenge to undergraduates. Students who have succeeded in algorithm-intensive courses such as calculus often find the abstract logic and nonprocedural nature of proof writing to be technically difficult, ambiguous and filled with potential errors and misconceptions. This mixed-methods study examines 23 undergraduate students' attempts to write one-to-one and onto proofs in an introductory abstract algebra course. Data collected consisted of six rounds of assessments on one-to-one and onto proofs, including homework, quizzes and exams. Using an existing framework of undergraduate proof writing, the researchers found that students' misconceptions and errors varied substantially by student and task, with one-to-one proofs presenting unique challenges. Implications for teaching and research include emphasis on the logic of proof approaches and providing structured proof frameworks to assist undergraduates with the procedural and conceptual challenges in learning to write proofs.


Synthetic food colors are a group of food additives widely used in many kinds of foods. Consuming a high quantity of synthetic color is a serious health problem especially for children. Therefore, the main purpose of this study was to assess the health risk from synthetic food color exposure in school children by the standard methodology for risk assessment of food additives advised by JECFA. This was done by comparing the estimated exposure of synthetic food color with the Acceptable Daily Intake (ADI). The exposure assessment was conducted in Suratthani province, Thailand. The consumption data of food containing color was collected from 430 students in the city and rural areas. Probabilistic risk estimation assessed from intake indicated that the exposure to these colors at average and high level (97.5 th percentile) of consumption did not provide harmful effects to school children because the degree of exposure was lower than the ADI of each color. Sunset yellow FCF was the color which posed the highest risk of exposure for secondary school children in urban areas. It was also the synthetic color that provided the highest risk of exposure for primary and secondary school children in rural areas and secondary school children in urban area at a value of 5.95%, 3.41% and 1.96% of ADI, respectively. The synthetic food color that provided the highest risk of exposure for urban primary school children was erythrosine, but the level was low at 4.06% of ADI. It was also found that the average exposure to most synthetic food colors in urban students was lower than rural students. Even though the levels of food color were not harmful to the students, but some food contained high amount of synthetic food color e.g. Sunset Yellow FCF in ice tea, fish ball. In addition, the usage of synthetic food color also found in foods that were not allowed to added color. Therefore, the usage of synthetic food color in the popular foods among students, especially meat and beverages needs to be carefully examined and strictly controlled.


This paper deals with real-time scheduling in a re-configurable multiprocessor system. Each processor is supplied with a renewable energy source, and uses a rechargeable energy storage. A reconfiguration scenario is any operation that consists in the addition, removal or update of tasks which may result in timing unfeasi-bility. In our work, each task is represented by a Proba-bilistic Directed Acyclic Graph (DAGP). Our contribution in this paper concerns the online feasibility problem that is issued from the reconfiguration process. We describe new approaches to solve this problem: the first one changes the timing parameters of the DAGP, the second one decomposes and migrates branches of the DAGP, the third one modifies the scheduling mode, and the fourth one deletes some tasks.


Currently, existing predictive methods are difficult to adapt to increasingly complex distributed power access and consumption, owing to the rapid growth of distributed accessing power grid scale and the uncertainty of time and space in new energy generation, such as poverty-alleviating photovoltaic (PV) and wind energy. In this paper, a real-time predictive method for intelligent monitoring and management of distributed power access is proposed. Firstly, the Voronoi algorithm is employed to divide the substation power supply area. Then, distributed power saturation is divided into four levels according to the penetration value associated with time matching of the network source and the under-construction capacity. Finally, the distributed power real-time intelligent warning method based on image processing is proposed. And the feasibility of this method was verified through two examples. This innovative partitioning method can overcome the shortcomings of the existing warning methods. Moreover, under the current situation of large-scale photovoltaic poverty alleviation in China, this method also can achieve coordinated optimization between distributed power supply and differentiated regional grid.

In this paper, the thrust density and thrust fluctuation of tubular C-core modular linear permanent magnet synchronous motor (TC-core MLPMSM) are optimized. In this paper, the characteristics of magnetic density distribution in the core of a tubular linear motor are analyzed. Based on the analysis, this paper proposes that trapezoidal stator slot will lead to a much larger thrust density than rectangular stator slot under the same volume and magnetic and electric load. Aiming at the problem of large force fluctuation in linear motor, modular structure is adopted and the detent force and thrust fluctuation are reduced. 2D finite element method (FEM) results are obtained to verify validity of the methods. Results show that the thrust density increases and the force fluctuation decreases after optimizations in TC-core MLPMSM.


The effects of human passage through low-density colonies of breeding jackass peguins Spheniscus demersus, and of human approach to high-density colonies were assessed. Passage disturbance led to egg loss through predation by kelp gulls Larus dominicanus and invariably frightened nest prospecting penguins away from the colony after the third or fourth intrusion, regardless of the interval between intrusions. Birds were disturbed and occasionally left the colony when an observer was less than 30 m from the edge of a high-density colony. Adult birds reacted most to a slow, direct approach and chicks to a staggered approach. The exodus rate of birds was higher at coastal than inland colonies, where no exodus was recorded. Results are discussed in relation to the conservation of the jackass penguin. This paper constitutes part of the commemoration of the 21st anniversary of the establishment of the Percy Fitzpatrick Institute of African Ornithology.


34 subjects with 36 obstetrical paralysis of the brachial plexus were studied. The diagnosis was made immediately after birth in the great majority. 5 pareses of the lower plexus, however, were only r


Electron micrographs from intraplasmatic inclusion bodies of human hepatocytes are described; these paracrystallic aggregations consist of helically arranged filaments. All the observed periodic structures within these bodies can be indicated as originating from the same compound by the use of the Frauenhofer diffraction pattern. Concerning the genesis of these characteristically structured bodies two possibilities are discussed: 1. A special polymeric form of fibrinogen and fibrin built up in vivo. 2. Polymerization of a monomeric enzyme, for example, glutamate dehydrogenase, to paracrystallic bodies by fixation-dependent cross-linkages.


25th September,2008,"12th China excavator industry annual conference" was held by China construction machinery association excavator branch.More than 300 people attended the meeting,which from the relevant state ministry,the leadership of the Association,the domestic excavator manufacturers,parts suppliers,agents and medias。 "Energy-saving and innovation" has become the main topic of the conference.China excavator industry has some problems.For examples,many enterprises came into excavator industry one after the other,especially small-sized excavator industry has great risk.Foreign brands have long-term competitiveness and growth,and would dominate market demand of China.Key components of hydraulic excavators will continue to restrict China's production capacity,but components supply will be improved.The import and export policies of second-hand excavators should be regulate strictly,to block the exporting of high energy consumption and high pollution excavator.
