Taking advantage of the wide (42 0 28 0 ) field of the CFH12K camera, we survey the young star population of NGC 6822 to unprecedented radial distances. We determine the age of the young stars by employing Gallart's et al. (1996b) method based on the presence of stars in dierent boxes in the CMD. We find that star formation took place up to 200 Myr ago in a wide area not always matching the current HI cloud. A50 Myr old association is identified, next to the HI void where no young stars are seen.


In recent years,the issue of how anxiety affects foreign language learning has attracted much scholarly attention abroad,and fruitful findings have been obtained.These findings can be summarized as follows.Firstly,language anxiety is a distinct construct of anxiety and should be differentiated from general anxiety.Secondly,language anxiety studies should focus on specific foreign language learning tasks.Thirdly,the effects of anxiety on foreign language learning have to do with the difficulty of the task that the learner is faced with.


Choledochal cysts are a congenital anomaly, and they show dilatation of the intra- or extrahepatic biliary tree. These cysts are uncommon in Western countries, but are not rare in Asian countries. Choledochal cysts are classified into five groups based on location or shape of the cysts. Types I and IV-A cysts are the most common types, which are associated with anomalous pancreaticobiliary junction (APBJ), but other cysts are not associated with APBJ. Types I and IV-A cysts appear to belong to a different category from other cysts embryologically. Type I and IV-A cysts accompany anomalies of the pancreas. Type I and IV-A cysts might occur when left ventral anlage persists, and with disturbed recanalization of the common bile duct. Endoscopic retrograde cholangiopancreatography is the gold standard for detecting APBJ, but it is an invasive procedure. Magnetic resonance cholangiopancreatography (MRCP) is a non-invasive imaging tool for detecting pancreatic and biliary trees. MRCP is the first-choice modality for diagnosing choledochal cysts and APBJ in pediatric patients. Cystoenterostomy is been performed because of high complication and mortality rates. Complete excision of the cysts with Roux-en-Y hepatojejunostomy is a standard procedure for choledochal cysts to prevent postoperative complications, including development of cancer. In this study, we review classification, pathogenesis, diagnosis, and treatment of types I and IV-A choledochal cysts.


A general and versatile technology to engineer light‐responsive protein‐based biomaterials can enable the manipulation and interrogation of proteins, pathways, and cells, and it will assist the design of "smart" light‐responsive biomaterials. This study reports the evolution of chromosomal aminoacyl‐tRNA synthetases (aaRSs) for azobenzene‐bearing unnatural amino acids (uAAs) with up to ≈40‐fold increased protein production and improved fidelity, as compared with a previously described aaRS. The evolved translation systems enable efficient and accurate incorporation of up to 10 instances of the various light‐responsive uAAs in elastin‐like polypeptides (ELPs). Azobenzene‐containing ELPs are capable of isothermal, reversible, light‐mediated soluble‐to‐insoluble phase transition, with up to a 12  °C difference in the ELP transition temperature upon cis‐to‐trans azobenzene isomerization. Furthermore, the incorporation of azobenzene‐uAAs in ELP diblock‐copolymers enables the creation of light‐responsive self‐assembled nanostructures. Finally, light‐responsive resilin‐inspired polymers are also generated by multi‐site azobenzene‐incorporation. The translation machinery evolved in this study can be used for the multi‐site incorporation of azobenzene moieties at the polypeptide level and constitute a universal methodology for the design of light‐responsive proteins and additional families of protein‐based biomaterials with customized and tunable light‐responsive behavior.


A class of continued fractions is discussed that generalize the real J-fractions, and which have the same relationship to orthogonal rational functions, multipoint Pad e approximants and rational moment problems as real J-fractions have to orthogonal polynomials, onepoint Pad e approximants and classical moment problems. The setting is as follows. A sequence f ng of interpolation points in R̂ n f0g is given. The space L consists of all rational functions of the form p(z)=!n(z) for some n where p(z) is a polynomial of degree at most n and !n(z) = (1 z= 1)(1 z= 2) (1 z= n). A positive linear functional M on the product space L L is given and de nes an inner product on L. A positive measure on R is a solution of the moment problem on L (on L L) if R1 1 R(t)d (t) = M [R] for all R in L (for all R in L L). The inner product on L, de nes an orthogonal sequence f'n(z)g of functions associated with the basis fzn=!n(z)g. The sequence f'n(z)g satis es a three-term recurrence relation associated with a continued fraction. The approximants n(z)='n(z) of that continued fraction are multipoint Pad e approximants to the Stieltjes transform F (z; ) = R1 1 (z t) d (t) of solutions of the moment problem on L L. Like in the case of J-fractions, a theory of nested disks can be developed.


This paper reports 28 cases of head and neck maligmant tumors treated by cryosurgery in our hospital from 1981 to 1933. The cryosurgical technique, freezing method, and cryosurgical indications are presented. 23 among 28 cases were cured and followed for 21 months without recurrence.


A cross sectional study was carried out among school going children of Ganaktuli slum area in Dhaka city, Bangladesh. A total of 183 stool samples were collected from children of age between 5 and 16 years of both sexes during May, 2017 to April, 2018. Collected samples were examined using Formal-Ether Concentration technique. 61.20% samples were found positive for intestinal parasites. Eight species of parasites were identified, where Entamoeba histolytica (3.83%), Giardia lamblia (6.01%), Diphyllobothrium latum (3.28%), Paragonimus westermani (3.83%), Ascaris lumbricoides (24.59%), Trichuris trichiura (12.02%), Ancylostoma duodenale (5.46%) and Enterobius vermicularis (2.19%) was recorded. Male children showed higher (63.95%) prevalence than female (58.76%). The highest and lowest prevalence (82.46 and 39.29%) were found among 8 - 10 and 14 - 16 years children, respectively. The highest prevalence of E. histolytica (7.02%), A. lumbricoides (38.60%), T. trichiura (14.04%) and A. duodenale (8.77%) were observed in 8 - 10 years age group; G. lamblia (7.41%), P. westermani (5.56%) and E. vermicularis (3.70%) in 11 - 13 years age group and D. latum (6.90%) was found highest in 14 - 16 years age group. Statistically it was observed that age groups had significant association with parasitic infestation (p < 0.05) but prevalence did not alter significantly according to sexes (p > 0.05). Highest abundance of parasites was recorded for A. lumbricoides.

Cervantes's Don Quijote and the characters within it owe their existence to the curious interplay of art and life that has come to epitomize the modern era. The novel is a text born of other texts, within which texts play an essential role in narrative structure, story, plot, and character development. Throughout Cervantes's novel, it is blatantly obvious that the text and all its characters are conceived, nurtured, and sustained by a fascinating and intriguing combination of inter- and intratextuality. Take, for instance, Cervantes's efforts to distance himself from his protagonist and present him as an autonomous character ("aunque parezco padre, soy padrastro de don Quijote" [79]); don Quijote's countless sleepless nights reading "libros de caballeria con tanta aficion y gusto" (98); the creation of the narrator Cide Hamete Benengeli; the scrutiny of Quijote's library by the priest and the barber, the series of interpolated tales; and the incorporation of other novels and genres (e.g. El curioso impertinente and Maese Perez's puppet theatre).It is probably safe to say that of all the interpolated tales in Don Quijote, the episode of Grisostomo and Marcela (I: 11-14) has received the most critical attention. No doubt this is due in large part to the extent to which the shepherdess Marcela's character embodies a strong sense of individualism, a feature that sets her apart from the other female characters in Cervantes's novel and in other works of the same period. In the words of Elvira Macht de Vera, "Marcela se transmuta en una libertad autosuficiente y se plantea problematica en el mundo de los seres corrientes y de sus actos cotidianos" (6). Curiously, though not surprisingly, what sets Marcela apart from other female characters makes her more like Don Quijote. Marcela is the one character who most closely mirrors the novel's strong-minded and free-willed protagonist. To quote Julio Rodriguez Puertolas: "Don Quijote descubre [en Marcela], sin duda con admiracion, la existencia de otra persona tan independiente y libre como el mismo, integerrima e individualista, sincera y honesta. Don Quijote descubre un espejo en que puede mirar un otro yo" (185). Like Don Quijote, Marcela confuses art and life and is driven by an innate desire to alter reality in order to achieve her personal objective. Like the idealistic knight, she is also deaf to those who offer her practical advice in an attempt to thwart her efforts. Marcela's behavior, as might be expected, is considered unnatural. She is sharply criticized by the other shepherds who characterize her as "cruel," "arrogante," and "desdenosa" (195). As a female character in the pastoral genre, what Yvonne Jehenson has called a "male fantasy, a microcosmic image of man's gender-inflected wish fulfillment" (19), Marcela is atypical because she does not conform to the traditional image of woman as the object of male desire.That Marcela is misunderstood by her fellow shepherds may be dismissed by the fact that they are victims of their textual and contextual circumstances. Less understandable, however, are a variety of critical studies that regard her as callous, cold-hearted, destructively selfish, and categorically out-of-character (see, for example, Herrero, Dunn, and McGaha, among others). For every study that has concluded that Marcela's character is "awkward," "humorous," and not "fully believable" (Finello 123), there is a more recent one that has defended her as a woman who actively resists objectification and inscription as the helpless female. These studies view Marcela as the embodiment of the "ideals of female liberty" (Laffey 553) and the subversion of "the male view of her as textual object" (Jehenson 29), a character willing to proclaim female subjectivity and establish her autonomy regardless of the consequences and in spite of how difficult it is for the characters within the novel and her would-be critics to accept her (El Saffar 159).Marcela's character has generated diametrically opposing critical views, which, as Ruth El Saffar has pointed out, divide "fascinatingly along gender lines" (158). …


Published investigations dealing with the special vocabularies of the branches of mathematics taught in secondary schools have been relatively numerous during the past three decades. Prominent among such studies are those by Pressey,1 Thorndike2 Remers and Grant,3 Georges,4 and Kunkel.5 The relationship between the vocabularies of mathematics and science, has, however, received relatively little attention from investigators. Always im portant, this relationship has recently taken on added significance as a result of the formulation of pre-induction and post-induction courses and materials designed to facilitate the training of men for armed service. More evidence, therefore, with respect to what mathematical terms are commonly found in textbooks of high-school science is needed both as a guide to the teaching of this vocabulary in the courses in mathematics taken prior to or coincident with those in science, and as a means of integrating more closely the work of mathematics and science in junior and senior high schools.


Historically, teachers had been delegated the primary responsibility for the organization and management of classroom instruction in US public schools. While this delegation afforded teachers professional autonomy in their work, it has also resulted in disparities in students' educational experiences and outcomes within and between classrooms, schools, and systems. In the effort to improve instruction and reduce disparities for students on a large scale, one reform effort in the US has focused on building instructionally focused education systems (IFESs) where central office and school leaders collaborate with teachers to organize and manage instruction. These efforts are playing out in a variety of contexts in the US, including in public school districts, non-profits, and other educational networks, and it is shifting how teachers carry out the day-to-day work of instruction. In this comparative case study, we investigate two IFESs in which efforts to improve instruction pushed against historic norms of teacher autonomy. We found that these new systems are not at odds with teacher autonomy, but rather these systems reflect a transition to more interdependent notions of teacher autonomy.


AARONG dairy area of Pabna comprises a major part to meet the demand of milk and meat production in Bangladesh. Various diseases including surgical affections reduce the fitness, efficiency and productivity of cattle in this area. There is a need to investigate the occurrence of surgical diseases to take proper preventive measures. Therefore, the prevalence of surgical affections of cattle was studied in four Upazilas of Pabna from December 2012 to May 2013. A total of 2390 cattle from different households were included and surgical affections were recorded. The overall prevalence was 44.3% in stall feeding system, among which surgical affections were more prevalent in Sujanagar Upazilas (13.3%), and the highest prevalent surgical affection was foot diseases (8.2%) followed by navel ill (6.3%), myiasis (4.6%), arthritis, hernia and wounds (3.6%). Overall prevalence of surgical affections was slightly higher in female cattle in comparison to males The prevalence of navel ill (11.3%), foot disease (11.1%), hernia (6.1%) and horn affections (4.9%) were found to be higher in male. Whereas, myiasis (5.9%), upward patellar fixation (2.8%) were found to be higher in females. There is significant (P<0.01) difference in the prevalence of hernia, upward patellar fixation, horn affection, foot diseases and myiasis between male and female. It was also observed that cattle of 0-1 year was affected more frequently with surgical affections (18.7%) among which prevalence of navel ill (15.5%), hernia (8.3%), myiasis (5.4%) and foot diseases (5.3%) were higher. In addition, foot disease was more prevalent surgical affection in cattle of more than one year. Moreover, significant variation (P<0.01) was existed in the prevalence of upward patellar fixation, foot diseases, arthritis and wounds among three age groups. However, results of the present study indicate that there is a strong relation among the prevalence of surgical affections, sex and age of animals. Moreover, foot disease is a common occurrence in stall feeding cattle in Pabna. DOI:  http://dx.doi.org/10.3329/pa.v24i1-2.19104 Progress. Agric. 24(1&2): 85 - 92, 2013


The Museum of the Institute of the Earth's Crust opened an exhibition devoted to Mikhail M. Odintsov (1911–1980), the prominent Russian geologist and the corresponding member of the USSR Academy of Sciences, who headed the Institute of the Earth's Crust from 1954 to 1976. He was among researchers who pioneered in discovering diamonds in Siberia, Russia. He determined promising diamondbearing areas in Yakutia. The kimberlitic nature wad established, and the diamondiferous kimberlite prospecting method was developed. Prospective diamondbearing capacities were forecasted for the southern part of the Siberian platform and the Prisayanie. The Angara-Vilui ore belt was defined as the largest mineragenic sub-province in the southern East Siberia. The exhibition was opened on 07 November 2011 when the All-Russia Conference devoted to the 100th anniversary of Mikhail M. Odintsov took place in Irkutsk. It presents photographs, personal belongings and documents that provide information about Mikhail M. Odintsov's childhood and youth years, pedagogical activities, field studies, researches, multidiscipline scientific organization, social and political activities. A collection of kimberlite samples from Yakutia and beyond supports the exposition. A model of the Mir kimberlite pipe is presented; it is the first diamondiferous kimberlite found in June 1955 and developed in Siberia.


the start of the study, systemic blood pressure increased to 95/65 mm Hg; after 2 weeks of treatment, the patient was able to leave the bed and to stay in a seat and was found to be amenable to a rehabilitation program. Our results suggest that sildenafil could be effectively and safely used in very old patients with secondary pulmonary hypertension, allowing the daily dose of furosemide to be reduced and thereby making escalating doses of loop diuretics unnecessary. The phosphodiesterase 5 (PDE 5) pathway is highly represented in the lungs, and sildenafil, a selective PDE 5 inhibitor, by making more cyclic guanosine monophosphate available, is able to induce a selective pulmonary vasodilation, which preserves the ventilation:perfusion ratio, as the improvement of arterial blood gases in our patients and in previous series indicates. This finding is consistent with selective or prevalent vasodilation of ventilated lung units; nonselective pulmonary vasodilation would expose the patient to an imbalance between ventilation and perfusion, thus worsening the gas exchanges and, ultimately, PaO2, PaCO2, or both. Baroreflex sensitivity decreases with age in healthy subjects, and deconditioning secondary to chronic diseases could further contribute to worsening vascular reflexes, putting frail elderly people at special risk for sildenafilinduced hypotension. Nevertheless, in a patient with severe pulmonary hypertension and systemic hypotension, sildenafil could improve systemic blood pressure and contribute to making the patient amenable to a rehabilitation program. This favorable result suggests that even severe hypotension coexisting with pulmonary hypertension does not exclude a trial with sildenafil, because relieving the pulmonary vascular barrage could improve left ventricular filling and, subsequently, arterial pressure. Alternatively, it cannot be excluded that sildenafil relieved arterial hypotension by increasing PaO2 and thereby improving heart function. Indeed, findings in hypoxemic patients with chronic obstructive pulmonary disease show that hypoxia impairs left ventricular relaxation and indirectly could depress the systolic function. The present experience cannot guarantee that any older patients with pulmonary hypertension and systemic hypotension will benefit from sildenafil. The risk exists that, in occasional patients, lack of pulmonary vascular effect and retained systemic vascular effect worsen rather than improving health status. Accordingly, it seems safe to monitor vital parameters and SPP at least on the occasion of the first dose of sildenafil. With this precaution in practice, sildenafil may be a valuable tool in the management of severe secondary pulmonary hypertension even in the very old.

I N RECENT YEARS there have been a conI siderable number of investigations on the epidemiology of staphylococcal infections originating in hospitals.39'21'' 2' The results indicate that carrier rates of hospital personnel and patients are quite high,'5'20 and that the nasal mucosa of the hospital staff constitutes an important reservoir of infection for patients.1 1",16 In addition, highly virulent strains acquired while in the hospital have been incriminated in serious outbreaks of staphylococcal infections among family contacts months after the patient has been discharged from the hospital. The purpose of this study wvas to determine the incidence of coagulasepositive staphylococci in a normal, unconfined population. This information wvas expected, in turn, to contribute to our understanding and evaluation of hospital carrier rates. The influence of race, sex, age, and season on this incidence is described.


Abstract : Tests were conducted in the Aerodynamic Wind Tunnel (4T) using 0.05- scale models to investigate the separation characteristics of the SUU-51 Laser- Guided Dispenser Munition (LGDM) from Triple Ejection Rack and Multiple Ejection Rack locations on the inboard and centerline pylons, respectively, of the F-4C aircraft. Captive-trajectory store separation data were obtained at Mach numbers from 0.66 to 0.90, angles of attack from 0.3 to 2.1, and a simulated altitude of 5000 ft. At selected test conditions, parent-aircraft dive angles of 30 and 45 deg were simulated. Free-stream force and moment data were also obtained on the SUU-51 (LGDM) model at Mach numbers from 0.66 to 0.95 at store angles of attack from -6 to 20 deg. Generally, the store initially separated from the parent aircraft without store-to-parent contact. However, most of the trajectories were terminated after short time intervals because of a rapid pitch and yaw motion of the store. This termination was the result of limitations imposed by the test installation, such as sting-to-parent-aircraft contact, a store support system travel limit, or a balance load limit.

We evaluate six conjectures and one theorem, as proffered by Metamath staff. The conjectures are not tautologous. The Tarski-Grothendieck theorem is also not tautologous. Metamath fails our analysis.


Field-cum-laboratory experiment was conducted to study the effect of pre-harvest spray of insecticides for control of pulse beetle in green gram at Entomology farm and department, B. A. College of Agriculture, Anand Agricultural University, Anand during Kharif 2017-18 to 2018-2019. The experiment was laid out in the randomized block design (Factorial) consisted of 15 treatment combinations involving two factors with three replications. Adult emergence of pulse beetle differed significantly due to preharvest spray of insecticides and different spraying schedules. The lowest number of adult emergence was recorded in treatment indoxacarb 14.5 SC followed by profenofos 50 EC and emamectin benzoate 5 SG. In case of spraying scheduled lower number of adult emergence was recorded in spraying at maturity as compared to others. In interaction effect significantly lowest adult emergence as well as lower number of egg laying, seed damage and higher percentage of seed germination was recorded in pre-harvest spraying of indoxacarb 14.5 SC 0.012 per cent (8 ml/10 litre of water) at pod maturity stage to check the infestation of pulse beetle during storage up to two months.


A new approach to noise characterization of microwave transistors is presented. It employs a novel noise measurement instrument, the multi-state radiometer, capable of simultaneous measuring the noise temperature and the impedance of one-port devices. Its unique measurement potential is achieved thanks to specific noise excitation of the device at the input of an RF total power radiometer. Due to gauging the power of interfering noise waves, its operation is analogous to that of six-ports and multi-state reflectometers, thus resulting in similar techniques of calibration and accuracy enhancement. Generally, the multi-state radiometer is calibrated using several impedance and noise temperature standards and after that can be used for measuring unknown devices at extreme low-power noise stimulus. This capability was utilized to characterize both the noise and small-signal properties of GaAs transistors using the cold-source measurement technique. Experimental results validate the novel noise measurement approach called as the multi-state radiometry.


The aim of this paper is to consider an alternative robust design method of integrated controls and diagnostics by making use of the so-called four degree-of-freedom (4-DOF) controller. This controller has 2-inputs and 2-outputs whereby the additional controller output is viewed as a diagnostic output which detects sensor and actuator failures. The 4-DOF controller is a simple case of the standard regulator framework; therefore, the design of integrated controls and diagnostics can thus be done in the framework of <inline-formula> <tex-math notation="LaTeX">$\mathcal {H}^{2}$ </tex-math></inline-formula> and <inline-formula> <tex-math notation="LaTeX">$\mathcal {H}^{\infty }$ </tex-math></inline-formula> whereby the latter gives the advantage of synthesizing the 4-DOF controller in a single step approach. Unlike previous methods, explicit state-space formulae are derived (in discrete-time) for a 4-DOF controller. For the <inline-formula> <tex-math notation="LaTeX">$\mathcal {H}^{\infty }$ </tex-math></inline-formula> case it stabilizes an augmented plant with respect to unstructured additive coprime factor perturbations whilst simultaneously providing robust control and diagnostic performance when uncertain plants are used. Moreover, the 4-DOF <inline-formula> <tex-math notation="LaTeX">$\mathcal {H}^{\infty }$ </tex-math></inline-formula> controller derived (albeit, of adequate complexity that can be further reduced using model/controller reduction techniques) is applied to a distillation system example to illustrate the effectiveness of the proposed unified framework.

This article examines the changing representation of technology in three of DeLillo's novels, White Noise, Cosmopolis and Zero K, and traces the conceptual and philosophical developments in his writing concerning the two key themes of disaster and mortality. Disasters witnessed through technological means consistently distance the 'real' from the event in earlier work such as White Noise, whereas in Cosmopolis, Eric Packer, the central character, yearns for disasters to happen to himself. DeLillo's latest novel Zero K represents a clear sense of ending and longing for disaster. Secondly, technology changes from promoting a fear of death in earlier works, to a fear of life in Zero K, highlighting the bleakness of life in a world ruled by technology. This article will discuss these two progressions in detail across the three novels, followed by a conclusion of the comparisons titled 'Changing Channels' for each theme, producing an original perspective of the diachronic changes through DeLillo's work.


In this short paper, we will provide a new explicit construction of binary MDS array codes with triple parities from their parity-check matrices, which contains array codes with array number 8 (8 bits=1 byte). In addition, to demonstrate the applicability of our MDS array codes, we present an effective decoding method aimed at the erased errors. Furthermore, a fast encoding algorithm of our extended MDS array codes is also explored, whose computational complexity is 2 XORs per bit when their code lengths approach infinity.


High humidity levels, which often prevail in hot equatorial countries, leave most passive cooling systems ineffective. Most developing countries do not design buildings for natural cooling, resulting in the extensive use of air-conditioners. The heavy energy-consumption and harmful gases emission of the traditional air conditioning systems contradict the concept of sustainability. Therefore, the optimising alternative means of cooling with very minimal energy become very desirable. An extensive study into the technological aspects of vernacular architecture in Brunei Darussalam's Kampong Ayer (Water Village) is presented in this paper. A scientific approach to the passive cooling techniques can improve and sustain its application. Research into this field is recognised as a key effort to achieve the future sustainability in these buildings. Passive cooling technique can achieve its optimum performance and potential benefit with careful and meticulous design. The efficiencies and limitations of the appropriate passive cooling techniques for hot and humid climates are justified and assessed. This study forms the essential starting point towards bridging new sustainable cooling technologies for the buildings on water.


Anti-slide pile is an important method for slope treatment,especially when the slide face is certain and the subterrane is stable,the method is proved to be prior. But if there exist more weak terrains under the slide face, a new slide face may be formulated after being reinforced and ideal reinforcement effect can not be achieved. Monitoring and analysis of anti-slide piles reinforcement effect on the west area slope of Chengchao Iron Ore are analyzed. The results indicate that there are shallow-layer and deep-layer slide faces in the slope after reinforcement. At first,there is only a shallow-layer slide face found before reinforcement,but a new weak face on the base of the first shallow-layer slide face is found after reinforcement and then,shallow-layer and deep-layer slide faces are found. However,anti-slide pile has effects only on the shallow-layer slide face because of its length. It is pointed out that the influence of ground water is an important factor for slope deformation.

TrEnDS in BaTTEry anD ELECTriC DrivE ComponEnTS Role of Battery and Electric Drive Components The environment has become a serious problem at the global level in recent years and countries around the world have embarked on activities aimed at realizing a low-carbon society capable of striking a balance between global warming prevention, CO2 (carbon dioxide) emissions reduction, and other measures for dealing with these environmental problems on the one hand and social progress and economic growth on the other. In Japan, the "New Growth Strategy (Basic Policies)" approved by the cabinet in late 2009 looks ahead to 2020 and establishes green innovation (innovation in the environment and energy fields) as a growth industry that draws on Japan's strengths. The policy identifies the necessity of achieving social progress and economic growth through active promotion of green innovation and by leading the world in finding solutions to these problems. Similarly, hitachi is seeking to focus its efforts on its Social Innovation Business by integrating the latest information and telecommunication systems technology with social infrastructure such as the power system, industrial, transportation, and urban development systems, and to contribute through hitachi products and services to a 100-million-t reduction in annual CO2 emissions by 2025. hitachi also sees battery and electric drive components (electric motors and inverters) as having a key role in supporting these products (see Fig. 1).

Finally, the problem of predicting random fields from incomplete information is discussed.


We introduce the Aumann fuzzy improper integral to define the convolution product of a fuzzy mapping and a crisp function in this paper. The Laplace convolution formula is proved in this case and used to solve fuzzy integro-differential equations with kernel of convolution type. Then, we report and correct an error in the article by Salahshour et al. dealing with the same topic.


Objective To investigate the effect of Helicobacter pylori (Hp) infection on oxidized low density protein (oxLDL) and carotid arterial atherosclerosis in patients with coronary heart disease. Methods A total of 159 coronary heart disease patients were recruited to this study. Cases with ≥50% stenosis in at least one of the three coronary vessels were defined as having coronary heart disease by angiography. And serum fibrinogen, lipid, urine acid, oxLDL, high sensitive C-reactive protein(hsCRP) and intima-media thickness (IMT) and plaque of carotid artery were examined in all subjects. Current Hp infection was determined in all study participants by means of a modified[~(13)C]urea breath test. All subjects were divided into 3 groups, including negative infection group, slight infection group and serious infection group. Results There were significant differences in the levels of serum total cholesterol, low density lipoprotein, hsCRP and oxLDL among 3 groups (P0. 05). The levels of these parameters metioned above were highest in CHD patients with Hp serious infection. The IMT in negative infection group, slight infection group and serious infection group were (0. 91± 0. 21), (1.03±0.40) and (1.21±0. 51)mm respectively. There were significant differences in IMT among three groups (P=0. 003). Conclusions Hp infection may increase the risk of carotid atheroselerosis in CHD patients. Hp infection might be involved in coronary atheroselerosis by modifying serum lipids, enhancing LDL oxidation and activating the inflammatory responses.


Perceptual indicators of multimedia quality have to be taken into account in order to build the truly end-to-end communication architectures of the future. This paper investigates the perceptual impact of differing multimedia presentation frame rates on user information assimilation and level of satisfaction. We apply the quality of perception (QoP) concept, which encompasses not only a user's ability to analyse, synthesise and assimilate the informational content of multimedia but also his/her satisfaction with the quality of a multimedia presentation. Our results show that higher frame rates, although resulting in a better-perceived level of quality and enjoyment, across a range of video content, do not significantly increase the level of user information assimilation.


Potential lymphatic drainage patterns from cutaneous melanomas of the head and neck are said to be variable and frequently unpredictable. The aim of this article is to correlate the anatomic distribution of pathologically involved lymph nodes with primary melanoma sites and to compare these findings with clinically predicted patterns of metastatic spread.

Obesity is a metabolic disease which has now reached epidemic proportions, becoming a major
health, social, and economic problem worldwide. Untreated obesity is associated with decreased
quality of life and is a significant risk factor for the development of other serious health problems,
such as diabetes and cardiovascular diseases. For this reason, new approaches to prevent
excess body mass and to support its reduction if necessary are being examined. Catechins extracted
from green tea – especially epigallocatechin gallate (EGCG) – are one of the most widely
investigated biologically active substances. In addition to the antioxidant, anti-inflammatory,
and anticarcinogenic properties of the catechins, they also exhibit a role in maintaining normal
fat mass and body mass. There are numerous research studies showing that regular green tea
consumption is associated with lower body mass, BMI, and waist circumference. In vitro and
animal experiments confirm beneficial effects of catechins on the energetic metabolism. These
compounds lower lipid and carbohydrates absorption in the intestine. Additionally, they affect
the energetic metabolism, lowering the rate of lipogenesis and adipogenesis, while stimulating
lipolysis and fatty acid oxidation, and increasing energy expenditure. Moreover, it has been established that green tea catechins have an effect on the glucose uptake in the insulin-dependent
manner – by GLUT4. The aim of the following paper was to review and summarize the literature
data concerning the role of green tea catechins in the prevention and treatment of obesity.


The reaction of 22 Na(p,γ) 23 Mg has been investigated at the Radioactive Ion Beam Line in Lanzhou(RIBLL) using a radioactive beam 23 Al. The β + delayed proton decay spectrum has been measured with the TOF Δ E method and zero degree detectors. The half life of 23 Al is determined to be T 1/2 =(476±45)ms by using a time scaler combined with the precision pulse generator,which is consistent with the other group's result of (470±30)ms. The known β + delayed protons at E r= 0.216, 0.278,0.438,0.479MeV have also observed in the experiment. The resonance strength of isospin analog state (IAS) is calculated. The resonance intensity of IAS is (11.4±6.0)meV. A new energy level of β + delayed proton decay has been identified at E x=8.916MeV,and their relative intensity also been obtained.


It is suggested that the decrease in the solar radius inferred from solar eclipse observations made from 1715 to 1979 reflects a variation of the solar constant that may be of considerable climatic significance. A general, time-averaged relationship between changes in the solar constant and changes in the solar radius is derived based on a model of the contraction and expansion of the convective zone. A preliminary numerical calculation of radius changes due to changes in the mixing length of the solar envelope is presented which indicates that a decrease in solar radius of 0.5 arcsec, as observed in the last 264 years, would correspond to a decrease of 0.7% in the solar constant, a value of large climatic significance. Limitations of the observational method and the numerical approach are pointed out, and required additional theoretical and observational efforts are indicated.


The emergence of city during the period of the Republic of China changed the administrative model based on the area since the Qin Dynasty.This paper discusses the emergence and development of city in this period and the locations of 151 cities and points out that cities first emerged in the coastal port regions due to their quick economic development and fast population growth.The establishment of city relied on its population and tax income.The traditional administrative centers could develop into cities if they had quick economic development and were the local economic center.


Language is the main important media of communication for human beings. Automatic speech recognition (ASR) or computer speech recognition is the method or technology developed to extract, recognize and translate the speech characteristics spoken by human into text by smart computerized devises. In this paper, we have developed speaker independent ASR for a rare and geographically important Indian dialect 'Chhattisgarhi'. For recognition and matching of each utterance spoken by people, we have extracted speech characteristics by using Mel frequency cepstral coefficient (MFCC) technique. The Machine Learning algorithms have been implemented on the MFCC features extracted from the self-collected chhattisgarhi speech dataset which consist of 19000 isolated words (95 words ∗ 200 speakers). The 10-fold cross validation technique has been implemented to improve the performance of the machine learning paradigms. The designed algorithm provides 99.84% and 94.25% of accuracy using ANN and multiclass SVM with k-fold cross validation respectively. The performances of the designed machine learning algorithms have been numerically validated based on the accuracy, sensitivity and specificity.


ABSTRACT In this paper, we address two challenging issues underlying spatial simulation using software agents immersed in virtual geographic environments (VGE). First, the way to describe virtual VGE models using accurate spatial decomposition approaches structured using graph theory techniques. Second, the use of graph abstraction techniques to support realistic and advanced navigation and path planning capabilities for software agents considering the VGE's characteristics. In order to illustrate our contributions to the growing field of spatial simulations, we present and discuss a case study involving an urban VGE model populated with agents who autonomously and differently interact with multiple abstractions of the same physical environment.


In November of 2005 a measurement series was conducted on different kinds of reference objects to compare the results of the FRM-II (ANTARES) and the Budapest (Radiography Station) research reactor in the field of neutron radiography, gamma radiography, classical tomography and discrete tomography by an ANDOR CCD camera and Imaging plate with BAS 2500 Scanner (contributed by AIDA software).


Herein, a mercury(II) ion fluorescent sensor (Z-3) with high sensitivity and immediate response is designed and synthesized. The sensor uses the phenazine group as a luminophore and sulfhydryl as a recognition moiety. The sensor is easily synthesized and it exhibits a remarkable blue shift with Hg2+. Correspondingly, its fluorescence color changes from yellow to blue. In addition, the low naked eye detection limit (10−5) of the sensor allows the identification of concentration limits. Moreover, the sensor could detect mercury(II) ions over a wide pH range (from 2 to 8), which indicates that the detection can be carried out in aqueous systems. In addition, test strips are fabricated, which could act as a convenient pathway for the recognition of Hg2+.


OBJECTIVE: To assess a set of dynamic visual function following optic neuritis (ON), and their putative role in the pathogenesis of the disease.
 BACKGROUND: We have recently reported that ON has prolonged debilitating effects on visual motion processing, accompanied by sustained reduction in motion-related cortical activity. Furthermore, motion processing was found to be correlated with latencies measured along the optic nerve. We suggested that this deficit may stem from reliance on the more precise timing of signals for motion processing which is impaired in demyelination. We suggested including motion perception as a functional marker of myelination degree within routine testing. However in the light of the cortical findings, aberrant reorganization of motion pathways after ON may also play a role. Herein we aim to differentiate between those two hypotheses.
 DESIGN/METHODS: 20 ON patients recruited 0-36 months following a first-ever unilateral ON and 20 control subjects were examined. Dynamic visual testing included Critical flicker fusion frequency (CFFF) considered as low-level dynamic processing; motion perception via object from motion (OFM) and via number from motion (NFM) extraction. Monocular and binocular Visual evoked potentials (VEPs) were recorded and visual quality of life questionnaires (NEI-VFQ-25, 10-Item Neuro-Ophthalmic Supplement) were performed.
 RESULTS: In ON patients, delayed VEP latencies and impaired CFFF, OFM and NFM were evident throughout all testing phase ( p ≤0.01 in comparison to controls for all functions). Furthermore, high correlations were found between VEP latencies, CFFF, NFM and OFM (r 蠅0.81, p < 0.0003 in all pairs). Dynamic visual tests9 scores were correlated with visual quality of life in the patients.
 CONCLUSIONS: The consistency of the deficit in all three dynamic visual tests, assessing higher and lower visual functions; and their correlation to the VEP latencies support the notion that motion perception is dependent on conduction latencies and is not driven by cortical mechanisms. Moreover, the correlation between dynamic visual abilities and visual quality of life may explain the sustained visual complains of ON patients. Disclosure: Dr. Shear-yashuv has nothing to disclose.

Purpose - The purpose of this paper is to propose a framework based on cash flow matching for computing the Solvency Capital Requirement under Solvency II. Design/methodology/approach - The time horizon of the insurance liabilities is typically longer than the maturities of bonds available in the market. With the assumption that a collection of bonds will be available for purchase in the future, the authors study the cash flow matching program under interest rate lattice models. Findings - The solution can be interpreted as the worst-case cost and the economic capital can be found accordingly. Originality/value - The paper illustrates the methodology of computing the Solvency Capital Requirement using a dynamic cash flow matching framework under lattice models. The proposed method is particularly useful for insurance products with a typical long time horizon when most duration matching techniques are not easily applicable.


Electromagnetic effects excited by intense relativistic electron beams in plasmas are investigated using a two‐dimensional particle code. The simulations with dense beams show large magnetic fields excited by the Weibel instability as well as sizeable electromagnetic radiation over a significant range of frequencies. The possible relevance of beam plasma instabilities to the laser acceleration of particles is briefly discussed.


We present a novel capability of the TV holography technique applied to the non-destructive testing of mechanical parts or structures with the form of a plate or a shell, which consists of the recording of high quality synthetic movies of the spatio-temporal evolution of instantaneous ultrasonic displacement fields of the surface under inspection. Moreover, in the case of narrowband acoustic excitation, movies of the spatio-temporal evolution of the acoustic amplitude and of the total acoustic phase can also be generated. Some examples of the application of the technique to flaw detection in aluminium plates using surface waves are presented. As a previous step for evaluating the context and the advantages of the new capability presented, a description of the state of the art with a comparative analysis about non-destructive testing techniques based on optical probing of ultrasound, focused on shell structures, is included in the first part of this article.

Reviews the book, Dreams and Personality: A Study of our Dual Lives by Frederick Pierce (1931). In contrast to many other psychological works on dreams, the present book deals mainly with subjects who are at least fairly well adjusted. This contribution then is made to the field of normal psychology rather than to abnormal. This book will be welcomed by many readers, both layman and professional. In general, these readers will find this book far from disappointing. (PsycINFO Database Record (c) 2006 APA, all rights reserved)


We report near-stoichiometric (NS) Ti:Mg:LiNbO3 strip waveguides fabricated starting from a Z-cut pure congruent LiNbO3 substrate in sequence by Tiand MgO-diffusion and post vapor transport equilibration. These waveguides with an initial Ti-strip width of 4-8 μ.m well support transverse magnetic mode, are single-mode at 0.98and 1.5-μ.m wavelengths, have a smooth surface and a loss as low as 0.1 dB/cm at 1.5 μm. The waveguides are NS and optical-damage-resistant, and have a homogeneous Mg concentration of 1.7 ± 0.3 mol% in the guiding layer. Such a waveguide is promising for nonlinear integrated optics.


The aim of this article was to summarize long-term research on the legal instruments of the Common Agricultural Policy in which agricultural activity and rural development are treated equally as an element of sustainable development. Conducted research allows one to advance the thesis that Common Agricultural Policy has evolved over the years from a narrow production approach to agriculture to a holistic approach in which farming is viewed as a harmonious, sustainable use and rational management of natural resources and elements of nature, recognized as a highly protected public good. Agricultural activity gains a new approach that goes beyond the sphere of private professional or business activity. As a result of the imposition of environmental obligations, serving to the public interest, and reimbursement these activities from public funds, agricultural activity becomes the sphere of protection and production of environmental public good and, thus, extends the traditional concept of public good. Implementing environmental protection instruments in farming activities has specific consequences. Implementing the imposed duties increases the cost of farming. Failure to comply with regulatory requirements in subsequent years may result in penalties even exceeding the greening amount received, which would mean a partial reduction in other payments.

The goal of this research project was to test the aerodynamic parameters like lift, drag, L\D ratio and also the pressure distribution on two authentic birds' wings i.e. pigeon and parrot .The main purpose of using two different birds' wings is to study the effectiveness of wing span and area, in their flight. This analysis was made using digital subsonic wind tunnel. Consequently it is necessary for us to study about aircraft flight with an emphasis on bird flight. As per the given theoretical results the lift and drag varied for both the birds. Though both the birds have the same ability to flap, for generating lift, the aerodynamic parameters varied because they had different velocities, and where adjusted at different angles of attack. The study of bird wing also gives the concept of alula which plays the major role and helps the bird to fly. It is a sensory anti-stalling structure and its activity depends on its shape and air pressure. In the present analysis the airflow over the bird's wings of pigeon and parrot with alula locked and unlocked was tested. On comparing it was found that the lift for the parrot's wing is greater than that of the pigeon, with the alula open and closed. The pressure distribution varied for both the birds considerably with varying angle of attack having its alula unlock. The results are found to be good so as to benefit the mankind in perceptive of the bird flight and advances in aircraft technology.


Objective To investigate the distribution and significance of CD20 positive cells in the early human embryo. Methods Distribution and morphology of CD20 positive cells in 10 specimens of human embryo aged from 6 to 7 weeks were brown,and studied with immunohistochemical method. Results 1.CD20 positive cells appeared in the liver of early human embryo.2.The immunohistochemical positive substances were brown,and found chiefly in the nuclei of B cells as unevenly-distributed granules,and were not detected in the cytoplasma and on the cell membrane.Conclusion The accuracy of location and distribution of CD20 positive cells in the nuclei of B cells of early human embryo liver may provide an important clue for further exploration of the functional mechanism of CD20 in the process of B cell proliferation and differentiation.


The horizontal and vertical distribution of temperature, salinity, magnitude of winds and Chl-a concentration were described, during the upwelling season in the Guajira, Colombian Caribbean, through hydrographic in situ and satellite information, showing variability in spatial distribution of Chl-a during the season with the maximum trade winds in the region. In both, the winds were mainly N to NE and favorable to coastal upwelling, although with a higher intensity during February of 2006. The changes in sea surface temperature and salinity allowed for the determination of the existence of three main upwelling nuclei: the coastal area between the Cabo de la Vela and Punta Gallinas (CV-PG), the zone between Puerto Bolivar and the Cabo de la Vela (PB-CV) and the zone between Santa Marta and the Parque Nacional Natural Tayrona (SM-PNNT). At the end of the upwelling season (February 2006), greater winds increase the offshore advection and the depth of the mixed layer, generating a mismatch between the upwelling and the planktonic biomass in the region.


Peroxo complexes of molybdenum and tungsten are attracting interest as oxidants in organic synthesis. As uranium somewhat resembles the group 6B elements, it was of interest to discover whether it would form analogous peroxo complexes which contain organic moieties. The preeminence of the UO/sub 2/ grouping distinguishes uranium from molybdenum and tungsten, however, and this factor may have hitherto prevented the generation of peroxo complexes from uranyl salts and organic reagents. The present paper describes the isolation and characterization of novel mono- and diperoxo complexes. These are found to be unusually stable, and they are relatively unreactive. They are the first reported examples of peroxo complexes of uranium which contain organic moieties.


Synthesis of chloroform from carbon tetrachloride via hydrodechlorination reaction is a new route with promising industrial prospect.Influences of platinum particle size,platinum precursors,(reaction) pressure,H_2/CCl_4 molar ratio and diluent gas on the hydrodechlorination reaction of CCl_4 to CHCl_3 were discussed.


The reliability of stator windings is very important for stable operation of generators, while they are under thermal, mechanical, environmental, and electrical stresses over years of operation. Utility companies are very interested in the remaining breakdown voltage of generators and utilize the corresponding data for maintenance or replacement of generators. In most cases the remaining breakdown voltage is measured by performing a non-destructive dielectric strength test. In this paper, the remaining breakdown voltage of a generator is predicted using statistical methods by comparison with actual measured data, considering the cooling method, maker, and years of use of generators, as a means to supplement the existing methods. This method can be used to minimize the errors that may occur when only the dielectric strength test is used.


We propose a novel, computationally efficient, and robust light detection and ranging (LiDAR)-only odometry framework based on truncated least squares termed T-LOAM. Our method focuses on alleviating the impact of outliers to allow robust navigation in sparse, noisy, or cluttered scenarios where degeneration occurs. As preprocessing, the multiregion ground extraction and dynamic curved-voxel clustering methods are proposed to accomplish the segmentation of 3D point clouds and filter out unstable objects. A novel feature extraction module is tailored to discriminate four peculiar features: edge features, sphere features, planar features, and ground features. As frontend, a hierarchical feature-based LiDAR-only odometry performs precise motion estimates through the truncated least squares method for directly processing various features. The preprocessing model and motion estimation precision have been evaluated on the KITTI odometry benchmark as well as various campus scenarios. The experimental results have demonstrated the real-time capability and superior precision of the proposed T-LOAM over other state-of-the-art algorithms.


The purpose of this study was to compare technology-based practice (Radio Baton/Digital Conducting System) to self-practice (recorded music) on the skill achievement of beginning conductors. Participants (N = 33) were undergraduate music majors from two beginning conducting classes randomly assigned to either the technology-based group or the self-practice group. Subjects worked for three, 15-minute sessions on the following skills: staccato conducting, legato conducting, and steadiness of tempo. The experimental design was a pretest-posttest using two conducting etudes to measure six dependent variables: staccato conducting, staccato presence, staccato steadiness of tempo, legato conducting, legato presence, and legato steadiness of tempo. Three expert judges scored videotaped pre and posttests with interjudge reliability ranging from .77 to .84. Six analyses of covariance tests (ANCOVA) were used to analyse the aforementioned dependent variables. A significant difference resulted between treatment and control groups for only the legato conducting variable (p = .05). The researchers concluded that a longer treatment period was perhaps necessary to produce a significant difference between the groups on the other variables.


The purpose of this research is to develop applications of thin-film L-C band-pass filters. We made 3-step L-C band-pass filters that consist of thin-film inductors and thin-film capacitors, determined the L-C constitution and characteristics of the filters, and investigated the Q value of each L and C by simulation. The filters thus produced are small (3.4×2.8×0.6 mm3 = 0.006 cm3), even when the substrate is included, and are applied in the frequency range of about 400 MHz. Their characteristics showed a low insertion loss of -9 dB at 400 MHz, and the wide band characteristics of 75 MHz were obtained for a bandwidth of -3 dB. A Q value of about 20 was obtained for a resonance tank circuit composed of thin-film L-C, and a Q value of 20-50 was obtained for a bridge capacitor containing thin-film capacitors. The values of L, C, and Q for the thin-film inductor, thin-film capacitor, and stray capacitor of the circuit were investigated by simulating the measured results.


It is a privilege and honor to have the opportunity to present the Kober Lecture at the premier meeting for physician-scientists and to have the lecture published in The Journal of Clinical Investigation. Like other members of the Association of American Physicians, I am often asked by younger physician-scientists, "What were the most important decisions of your career?" On reflection, there were three, which I will review briefly before presenting an overview of our recent work on fatty liver disease (FLD), a burgeoning health problem in the Western world. First career decision. In 1979, while an intern in medicine at Columbia Presbyterian Hospital, I made the first and most important decision of my career, and of my personal life. I decided to marry my late husband, Dennis Stone (Figure 1, left), who was then a senior resident. Dennis had attended the University of Texas (UT) Southwestern Medical Center, and wanted to return there for subspecialty training. So after completing my internship at Columbia, we moved to Dallas and I continued my clinical training at UT Southwestern. In Dallas, I met three outstanding mentors who changed the trajectory of my life. The first was the late Dr. Donald Seldin, Chairman of Internal Medicine (Figure 1, middle). I was a proverbial "late bloomer." Only after becoming chief resident of medicine did I [...] AAP George M. Kober Lecture


The present study evaluates the effect of wheat flour particle sizes on the chemical and rheological properties of flatbread dough. Three wheat flour samples with particle sizes smaller than 125μm, 125-150μm and 150-180μm were examined for their chemical and rheological attributes. Flour with particle size of


Account posts belonging to the chief of DPD National Democratic Party Cirebon District Sukryadi, S.E. was reported by the Radar Cirebon Daily Newspaper by the title " MENJADI PEMIMPIN JANGAN TAKUT SAMA ALLAH, APALAGI TAKUT SAMA UNDANG-UNDANG, KALAU SAYA DIPERCAYA JADI BUPATI RAKYAT SEGALANYA BAGIKU" (Being a leader do not afraid to Allah, even to law. If I am trusted to become Regent, the people is everything for me) The above article has become viral in various social and electronic media. Moreover, it has made anxious Muslims in Cirebon in particular and West Java in general. It was finally reported to the Cirebon Police in 2017 by a number of Cirebon Islamic Mass Organizations led by H. Sugiyono, S.T. But unfortunately this reporting did not lead to a court, so that legal certainty for Reporting Parties and Reported Parties becomes unclear, Legal Supremacy could not be felt by the public. In the case referred to the Cirebon Police Investigator through SP2HP clearly stated that the first was Not Enough Proof, the second Fatwa of the Cirebon Regency MUI was not included in blasphemy so that this case the investigation could not be followed up to the investigation. From the reasons presented by the Cirebon Police Investigator through the SP2HP, it invited various questions for the Author. This is where the author was interested in conducting research in this field. The problems discussed are how the effectiveness of law enforcement against blasphemy crime in the jurisdiction of the Cirebon district police. The research method used was juridical approach, it was used to obtain primary and secondary data and both data were analyzed qualitatively which also were compiled logically, systematically and juridically. Based on the results of research in handling criminal cases of blasphemy in the jurisdiction of the district police of Cirebon was less than optimal. It was hoped that in the future, law enforcement must be in accordance with the Criminal Code and the existing legislation. Keywords: Convey the truth even though it is bitter


COVID‐19 pandemic has affected every country in many ways. Its substantial economic impacts are causing businesses to fade, pushing many nations into an economic downturn. This exposes organizations worldwide to unique risks which cannot be foreseen with conventional methods of risk analysis. This research is part of a broader action design research project conducted in collaboration with industry partner to answer an important research question: How to extend PESTLE risk analysis model to assess pandemic preparedness? In this context, the health factor is added to extend the traditional PESTLE risk analysis model. Furthermore, the interdependence between PESTLE factors has also been investigated, which has not been discussed before. The contribution of this research is the novel PESTLE+ risk analysis model that will help individuals and businesses to improve their understanding of the health crisis, such as the COVID‐19, adjust accordingly and eventually endure the ongoing crisis, which is driving most businesses into liquidation.


Humans being a social animal need physical presence of their own kind to learn and educate themselves. COVID-19 has increased the need and desire for oxytocin more than any time in history of education. The purpose of this research project was to look at how pandemic-induced remote learning has reduced students' social interaction, and impacted their education. With the ability to turn off audio and camera, struck in unproductive environments, students feel not only disengaged, isolated but overly anti-social. For our research, we recruited 25 undergraduate biomedical students at the University of Plymouth, England to survey their experiences with online learning, engagement with the technology and how it has affected their ability to learn in the void of physical presence. Our preliminary data suggests that (84%) of these students agreed that online/remote learning has impacted learning and made them crave for bonding to their classmates. However, for a small percentage (16%) said it did not make any difference. This initially highlights the issue that online learning is of the students seem to have no effect. These cohort of the students also seem to identify themselves as "introverts" and they also seem to have enjoyed being less sociable. We conclude that a statistically significant number of students proved to need a social environment conducive to learning and current pandemic limited that aspect. A social and a societal element of a happy civil environment is needed for not only healthy mind and body but also for a healthy and fruitful education world. A well-known bonding hormone "Oxytocin" is a prerequisite for human learning environment, and we don't see the virtual world to take that over in any time soon.


This paper advances the Domain Segmentation based on Uncertainty in the Surrogate (DSUS) framework which is a novel approach to characterize the uncertainty in surrogates. The leave-one-out cross-validation technique is adopted in the DSUS framework to measure local errors of a surrogate. A method is proposed in this paper to evaluate the performance of the leave-out-out cross-validation errors as local error measures. This method evaluates local errors by comparing: (i) the leave-one-out cross-validation error with (ii) the actual local error estimated within a local hypercube for each training point. The comparison results show that the leave-one-out cross-validation strategy can capture the local errors of a surrogate. The DSUS framework is then applied to key aspects of wind resource assessment and wind farm cost modeling. The uncertainties in the wind farm cost and the wind power potential are successfully characterized, which provides designers/users more condence when using these models.


Bering makes a good case for turning attention to an organized system that provides the self with transcendental meaning. In focusing on the evolutionary basis of this system, however, he overlooks the self-organizing properties of cognitive systems themselves. We propose that the illusory system Bering describes can be more generally and parsimoniously viewed as an emergent by-product of self-organization, with no need for specialized "illusion by design."


Five cotton genotypes were evaluated over a 2-year period to determine effects of thrips injury on leaf development and yield under 2 different control methods and in untreated plots. Genotypes with pubescent leaves exhibited a high degree of resistance to thrips injury as measured by leaf area development, and yields were not significantly different regardless of treatment. Untreated glabrous types showed a significant reduction in leaf area development. However, when treated with a systemic insecticide at planting, glabrous types exhibited increased leaf area and greater yields. Foliar insecticide treatments made after thrips injury appeared did result in some improvement in leaf area development but did not result in increased yields in the glabrous genotypes.


Schooling helps to take on the image of "Self" by integrating the meanings and narratives of our culture, identifying oneself with its values, including social ones. Integration is viewed by the authors as a process bringing multifarious meanings together, into a single interface between the meanings of various subjects and objects of the pedagogical process. It is proved that such approach encourages students to make a certain axiological choice, the first manifestation of meaning. Selected elements of pedagogical process - problems, problems-antinomies, events, concrete facts, personalization - combine various contents, make them into a single whole, creating prerequisites for axiological choices. It was found that the greater is the meaningful potential of integrated knowledge in the choice situations, the higher is the personal relevance of the problem for the student; events, specific facts and "acting out the characters" should affect the emotional and aesthetic sphere of the student. Due to this the axiological choice will be based on inner emotion, experiencing which is an indispensable prerequisite of personality development


This is a follow-up on a previous study on school age French first language newcomers to English speaking Ontario that showed attitudes and concerns around welcoming strategies and integration policies put in place at the Provincial level. New paths were delineated as a result of recommendations made. The findings led to the formulation of policy recommendations as well as follow-up guidelines for the French school system in Ontario, keeping in mind newcomers' needs as well as looking at the local community where these persons were interacting, namely as regards welcoming mechanisms and strategies to facilitate integration into the community. Since then, a number of implementations have been made in order to follow-up on initial observations regarding points such as the need to take into account attitudes towards diversity and the need of a collective effort. In this paper we discuss the study results, compare the ways implementations were made as well as report on the present situation through the analysis of several recent Ministry documents. The most interesting aspect emerging from the process appears to be the consistency in which consecutive Ministry documents address the relevant issues with a progressive zeroing in on detail as if using a zoom lens with the intention for objectives to be met through progressive adjustments. Overall, the diverse documents published, including the recently recommended implementation guidelines to 'support each pupil' appear to satisfy most concerns expressed in the initial study.

Objective Pesticide exposure has been linked to increased risk of cancer at several sites, but its association with risk of myelodysplastic syndromes (MDS) is still unclear. A meta-analysis of studies published through April, 2014 was performed to investigate the association of pesticide exposure with the risk of MDS. Methods Studies were identified by searching the Web of Science, Cochrane Library and PubMed databases. Summary odds ratios (ORs) with corresponding 95% confidence intervals (CIs) were calculated using random- or fixed-effect models. Results This meta-analysis included 11 case-control studies, all of which demonstrated a correlation between pesticide exposure and a statistically significant increased risk of MDS (OR = 1.95, 95% CI 1.23–3.09). In subgroup analyses, patients with pesticide exposure had increased risk of developing MDS if they were living in the Europe or Asia and had refractory anemia (RA) or RA with ringed sideroblasts (RARS). Moreover, in the analysis by specific pesticides, increased risk was associated with exposure to insecticides (OR = 1.71, 95% CI 1.22–2.40) but not exposure to herbicides or fungicides. Conclusion This meta-analysis supports the hypothesis that exposure to pesticides increases the risk of developing MDS. Further prospective cohort studies are warranted to verify the association and guide clinical practice in MDS prevention.


The invention relates to an electrostriction composite material which comprises a flexible macromolecule substrate and a plurality of carbon nanotubes dispersed in the flexible macromolecule substrate, wherein the electrostriction composite material also comprises a plurality of bubbles distributed in the flexible macromolecule substrate. The preparation method of the electrostriction composite material comprises the following steps of: providing a great deal of carbon nanotubes and flexible macromolecule material precursors; mixing the carbon nanotubes and the flexible macromolecule materialprecursors to obtain a mixed solution; adding a foaming agent into the mixed solution and solidifying the mixed solution to obtain the electrostriction composite material. As the foaming agent is added in the preparation process of the electrostriction composite material, bubbles can be generated in the electrostriction composite material and the heat expansion, cold contraction effect of air is particularly remarkable, and the electrostriction composite material has higher expansion and contraction ratio. The electrostriction composite material can be used in the fields of artificial musclesor brakes, and the like.


A 50-year-old woman was referred to us by her family physician because he had seen "a hole in her eardrum."The patient's history included many ear infections with episodes of drainage during childhood, but none since then . On examination of the left ear, we observed a scarred tympanic membrane with a thin neomembrane posterior to the malleus (figure). The malleus appeared to be normal, but the incus was not visible. The right ear also showed signs ofthepatient's previous infections.The512-Hztuning fork test lateralized to the left ear, and air conduction was better than bone conduction in both ears . Her audiogram revealed an air conduction pure tone average of 25 dB and a bone conduction average 15 dB. The patient did not complain of hearing problems. This case is an example ofa severely scarred tympanic membrane in an asymptomatic patient. The scarring occurred as a resu ltof'the patient's chi ldhood infections. Her hearing was low-normal, and she had a minimal air-bone gap . No further treatment was indicated. The patient and the referring physician were reassured that she did not have "a hole in her eardrum" and that her condition would not progress.

Agricultural officers were the grass root level workers who worked directly with the farmers in implementing the development activities. Competency and satisfaction of them on their job makes all the difference in smooth functioning of the development initiatives. Problems encountered by them need to be revised according to the suggestions given by them for successful implementation of the extension delivery system. The present study was conducted in 3 districts of Andhrapradesh viz., Chittoor, Cuddapah and Nellore with 90 sample size following ex-post facto research design. Political interference, farmers' interest in subsidies rather than technology and no proper office facilities were the major problems experienced by the agricultural officers which affected their competence and satisfaction levels. Suggestions offered by them to improve their competency and satisfaction were good audio-visual aids, conveyance facilities and good working environment and office facilities.


The paper presents new developments of the method and the design of an operating element of a conveyor of a root crop harvester, which is highly functional, since except for transportation, it provides careful cleaning of root crops from soil impurities and crop residues. The results of theoretical calculations aimed at the determination of effective design parameters and power characteristics of such an operating element are covered. The pattern of root crop motion along the technological channel of a conveyor-cleaner has been defined and the amount of root crop damage when contacting bars on the conveyor belt has been determined.


Climate change, poverty, and economic inequality are some of the threats to civilization in today's cities. This has given rise to the development of smart cities as a solution to the threat. However, this smart initiative did not solve the problem. In the face of this predicament, in order for cities to maintain their position, civic engagement must be undertaken by involving citizens in finding a collective solution with the support of smart library. Cities cannot plan or position themselves effectively until they grasp and exploit the existence of the smart library. The chapter explores the practical application of smart libraries to civic engagement. It identifies smart library strategies for building civic engagement in smart cities. The chapter also identifies possible challenges to smart library initiatives in smart cities and makes recommendations.


Using the silver-sodium ion exchange process in a special optical glass, different types of gradient-index cylindrical microlenses and microlens arrays have been fabricated. High numerical aperture single cylindrical lenses are produced in thin glass slabs without any diffusion masks. Depending on the desired index profile accuracy, a two- or three-step ion exchange process is used, the maximum numerical aperture which can be achieved is about 0.6. Contrary to other lens fabrication techniques, lenses of different focal length can be produced very easily, and both focussing and diverging lenses are possible. A series of systems, combining different lenses, have been realized for anamorphotic single-mode laser diode beam transformation and high-brightness laser diode beam forming. Arrays of cylindrical lenses of moderate numerical aperture (about 0.2) have been realized by electrical field assisted ion exchange through 1D mask structures. These lens arrays have been successfully applied to multiple-stripe pulsed laser diodes for efficient reduction of the output beam divergency, thus enabling a more efficient coupling of the output power to multimode fibers.


The burst of data leads to new requirement for high capacity of communication networks, bringing more activities for the industry. Some institutes public long term traffic forecasts for individual countries or continents even for the world, few of which have their forecasting methods known to the world. However, long term traffic forecasting is important for the industry to form a long-term strategy for communication development. A long term traffic forecast algorithm is proposed in this paper, and a case study of traffic forecast for China in 2020 is represented as a proof for the proposed algorithm.


Over these past years, formal reasoning about contracts between parties participating in a transaction has been increasingly explored in the literature. There has been a shift of view from one viewing contracts simply as properties to be satisfied by the parties, to one in which contracts are considered as first class syntactic objects and which can be reasoned about independently of the parties' behavior. In this paper, we present a contract calculus to reason about contracts abstracting the parties' behavior using a simulation relation—effectively a calculus of contracts regulating interaction between parties. We show how the calculus can be used to support the runtime monitoring of contracts and apply it to a plane boarding system case study.

As a rubric, History of Cartography has two distinct connotations: (i) the chronicle of technical and intellectual developments surrounding mapmaking and map use and (ii) the interdisciplinary endeavor that invokes historical context in studying both the map as a visual object and the societal impacts of cartographic technology and mapping activity. (It should not be confused with historical cartography, the mapping of past events by historians and historical geographers.) A third and equally pervasive connotation is the comprehensive History of Cartography initiated by J.B. Harley (1932–1991) and David Woodward (1942–2004) and published by the University of Chicago Press. Because the several volumes of the History reflect major divisions in map history, the series provides a convenient framework for much of this entry, which also identifies important English-language synopses and appropriately emphasizes developments since 1900, including dynamic maps and geospatial technology. This entry also examines academic activities, including conceptual frameworks, key individuals, and the institutional apparatus of map collections, exhibitions, conferences, and journals. Encompassing geospatial technology, this entry demands a definition of map with two levels: the narrow, traditional sense of a graphic framework whereby symbols representing geographic features facilitate navigation, planning, and general understanding (Harley and Woodward 1987, xv–xvii) and the broader, more recent sense of

In this paper, the non-holonomic characteristic of a free-floating space robotic system is used to plan the path of the manipulator joints, by whose motion the base attitude and the manipulator joints attain the desired states. Here, we parameterize the joint trajectory using sinusoidal functions, whose arguments are high-order polynomials. Then, we define the cost function for optimization according to the constraint conditions and the accuracy of the space robot. Finally, genetic algorithms (GAs) are used to search for the solutions of the parameters. Compared with others, our approach has advantages as follows. (i) The motion of the manipulator and the disturbance on the base are practically constrained. (ii) The dynamic singularities cannot affect the algorithm since only the direct kinematic equations are utilized. (iii) The planned path is smooth and more applicable for the control of the manipulator. (iv) The convergence of the algorithm is not affected by the attitude singularity since the orientation error is represented by quaternion, which is globally singularity-free. The simulation results of the spacecraft with a 6-d.o.f. manipulator verify the performance and the validity of the proposed method.


OBJECTIVE
to assess the relation between alcohol intake and mortality among seven cohorts of middle-aged and elderly Danes.

DESIGN
Prospective population study with baseline assessment of alcohol- and tobacco consumption, educational level and body mass index, and a mean of 11.5 years follow-up of mortality.

SUBJECTS
16304 men and women aged 50 years or more.

MAIN OUTCOME MEASURE
number and time of deaths from 1974 to 1995 as ascertained by the national central person register.

RESULTS
the effect of alcohol intake on mortality did not differ between middle-aged (50-64 years, mean = 56.6 years) and elderly subjects (>64 years old, mean = 69.9 years). There was a U-shaped risk function in both age groups, which persisted also when adjusting for age, sex, smoking habits, level of education and body mass index. Abstaining women had a relative risk of 1.29 (95% confidence limits 1.17-1.42) as compared with light drinkers (1-6 (drinks per week), while the relative risk for abstaining men was 1.22 (95% confidence limits; 1.08 to 1.37) as compared with light drinkers. Heavy drinking women (>28 drinks per week) had a relative risk of 1.23 (95% confidence limits; 0.85 to 1.78) and heavy drinking men (more than 69 drinks per week) had a relative risk of 2.11 (95% confidence limits 1.66-2.69), both compared with light drinkers.

CONCLUSION
among the middle-aged and elderly women and men, a light alcohol intake is associated with lower mortality than abstention or heavy drinking.

From the literature review, it is apparent that there is a gap in quantifying the performances of multitone waveforms specifically for radar applications and experimental results not commonly found. This paper focuses on the radar performance analysis of multitones with P3 phase-codes in simulation and experimentally to determine the effect of hardware on radar performances. For this purpose, a software-defined radar (SDR) approach has been used, including a digital core with hardware in-the-loop controlled by MATLAB and an analog front end that uses bandpass sampling and a reference channel. The proposed radar setup with processing algorithm has been evaluated in terms of processing time, showing that a real-time implementation on the latest field programmable gate array chipsets is feasible. This approach is flexible and entirely arbitrary waveforms can be generated with an instantaneous bandwidth up to 800 MHz. All the experimental results presented in Section IV are beyond the state of the art and bring novel insight into the impairment of SDR.


Objective To observe the status of platelets activation in cerebral infarction.Methods Flow cytometric immunofluorescence was used to check the molecular marker,the fibrinogen receptor(FIB-R) and P-selectin(CD62P) of circulating activated platelets in patients with acute cerebral infarction.Results Compared with normal control group,both the expressions of FIB-R and CD62P were singnificantly increased in patients with cerebral infarcton(n=43) and in patients with larcunar infarction(n=47).The expression of FIB-R in patients with cerebral infarcton was more common than that in patients with larcunar infarction,and the expression level remained high in the 7th day after the attack.There was no difference observed in platelet activation between the patients with or without oral aspirin prior to the attack.Conclusion Both CD62P and FIB-R are sensitve markers for detecting circulating activated platelets.Activated platelets exist in cerebral infarcton and larcunar infarction as well.


The production rates of ultracold neutrons (UCN) from cold neutrons on gaseous, liquid, and solid deuterium targets have been measured. The comparison of the measured and calculated UCN production on gaseous {sup 2}H{sub 2} is used to calibrate the simulated target extraction and transport efficiencies of the experimental apparatus. The production cross section in solid {sup 2}H{sub 2} at 8 K for UCN with energies between 0 and 250 neV is R{sub solid,8K}={sigma}{sub solid,8K}{sup CN{yields}}U{sup CN} {rho}=(1.11{+-}0.23)x10{sup -8} cm{sup -1}. This value is consistent with other experiments in which UCN had been extracted from {sup 2}H{sub 2}. The value also agrees with calculations using the incoherent approximation and a simple Debye model and corroborates predictions for UCN densities expected at the high-intensity UCN source at the Paul Scherrer Institut. The temperature dependence of the UCN production in solid {sup 2}H{sub 2} down to 8 K can be explained within the same model when multiple-phonon excitation is included.


Fundamentals and options of modeling cortical processes of binocular vision are dealt with in this paper. Physiologically characterized cell types of the visual cortex are modelled and used as basis of a network implementing a simulation of the binocular vision. An attempt is made to establish correlations between typical activity patterns of visual cortical cells and the network incorporating them.


– Growing pressures from development activities, on aquatic environments in South American countries, have created an urgent need for tools to measure the quality of aquatic systems. The index of biotic integrity, based on fish assemblages, elaborated in North America, constitutes a basis for the development of these tools. However, its direct application is problematic in regions having a rich and diverse ichthyofauna and where the knowledge of fish species ecology is incomplete. The response of taxonomic or trophic groups is often unknown and the selection of fish assemblage metrics cannot be based on previous knowledge, as in intensely studied regions. This work proposes a method, similar to the approach recently pursued in Europe, based on comparing the variability of fish assemblages in reference situations with their variability influenced by human-induced perturbations. The method was developed from 53 samples of 27 reaches in 7 hydrographic basins of French Guiana. For each of 28 fish assemblage descriptors, stepwise multiple linear regressions with 28 habitat variables were carried out. The residuals of the models obtained were used as candidate metrics independent of natural environmental factors. Nine metrics showing significant di ff erences between reference and disturbed samples were selected to constitute the index. The index was validated by analysing a temporal data series obtained from a reach disturbed by dam construction.
