In this paper, a polarization-insensitive and compact frequency selective rasorber (FSR) with two independent transmission windows and three absorption bands is presented. The proposed FSR is a two-layer structure, whose upper layer is a dual bandpass filter and the bottom layer is a lossy absorber, separated by an air spacer. The bottom lossy absorber is constructed by four folded rings loaded with four resistances and four capacitances, which realize a transmission response with two passbands and three lossy bands. As to the upper lossless filter, a double four-legged slot is etched on a square patch, which implements the same two transmission bands as the bottom layer. The two transmission bands of the FSR are at 5.3 GHz and 7.6 GHz with low insertion loss of 0.068 and 0.119, respectively. Three broad absorption bands whose absorptivity is greater than 80% in the 2.96-3.96 GHz, 6.14-6.94 GHz and 9.37-11.58GHz are realized. The polarization insensitivity is commendable, and the angular stability of TE and TM polarizations could up to 30° are achieved by the symmetric and compact structure.

The laws of functioning of discrete deterministic dynamical systems are investigated, presented in the form of automata models defined by geometric images. Due to the use of the apparatus of geometric images of automata, developed by V.A. Tverdokhlebov, the analysis of automata models is carried out on the basis of the analysis of mathematical structures represented by geometric curves and numerical sequences. The purpose of present research is to further develop the mathematical apparatus of geometric images of automaton models of systems, including the development of new methods for recognizing automata by their geometric images, given both geometric curves and numerical sequences.


Received: 19 June 2021 Received in revised: 21 July 2021 Accepted: 24 July 2021 Available online: 9 August 2021 DOI: 10.22034/ajgc.2021.291239.1307 Electricity generation has external costs that are mainly imposed on people who have no role in electricity generation. External or external costs are formed when the economic activities of one or more groups negatively affect another group or groups. For instance, construction and operation of thermal power plants emit carbon dioxide, sulfur oxides, and nitrogen, which can negatively affect buildings and human health. To determine the external costs of a unit, it is necessary to estimate the emission effects on the environment. In this study, the estimation of social costs of SO2, NOX, and CO2 emissions from fission and nuclear fusion power plants has been done for the first time by modifying the existing and related global coefficients. The scenarios used in the study include carbon trade scenarios and statistical indicators of life. First, a study was conducted on seven technologies in Iran, and then the results were compared to the entire world energy production industry. The final results show that the fusion and fission technologies performed well in a comparative cost analysis (161 and 127$/MWh, respectively). Also, cost analysis shows that the fusion power has the least health care costs (7$/MWh), which can be interpreted that fusion power is greener than the other powers, and after that comes fission with 24$/MWh. © 2021 by SPC (Sami Publishing Company), Asian Journal of Green Chemistry, Reproduction is permitted for noncommercial purposes.


All solid-state sulfur oxides (SO,,) sensor devices combined with a sodium ionic conductor (Na 5 DySi 4 O 12 ) disk and metal sulfide-sensing electrodes synthesized via solution routes have been systematically investigated for the detection of SO 2 in the range of 20-200 ppm at 150-400°C. Among the various sulfide-sensing electrodes tested, the metal monosulfide-based electrodes gave good SO 2 sensitivity at 400°C. The Pb 1-x Cd x s (x = 0.1, 0.2)-based solid electrolyte sensor element showed the best sensing characteristics, i.e., the EMF response was almost linear to the logarithm of SO 2 concentration in the range between 40 and 400 ppm, with a 90% response time to 100 ppm SO 2 of about 3-15 min, and also showed high selectivity to SO 2 at 400°C.


The "Metelka Act", which laid out the procedure for the establishment of new minority schools, was, in terms of nationalities, the most important of the large number of educational laws issued following the foundation of the Czechoslovak Republic. Although the act made it possible for all minorities to build schools, under the given political conditions it tended to accommodate the needs of Czech national education in particular. Many Czech organisations and societies, such as the Central School Foundation, branches of Sokol, professional teacher organisations and many regional women's and youth organisations (including, in South Moravia, the National Union for Southwest Moravia), had an interest in the establishment of Czech minority education. This paper, in addition to a theoretical section on Czech minority education, also offers a concise look at the situation in minority education in three districts in the former German language island to the south of the historical centre of the City of Brno.


From the nature of the algorithms for data mining we note that an XML framework can be represented using graph matching algorithms. Various techniques currently exist for graph matching of data structures such as the Adjacency Matrix or Algebraic Representation of Graphs. The Graph Representation can be easily converted to a string representation. Both Graph and String Representations miss semantic relationships that exist in the data. These relationships can be captured by using semi-structured XML as a representation format. We already have an approach to integrate different data formats into a Unified Database. The technique is successfully applied to diverse Protein Databases in a Bioinformatics Domain. An XML representation of this comprehensive database preserving order and semantic relationships is already generated. In this paper we propose an approach to a Semantic Protein Map (PMAP) by building a shared ontology on our structured database model. This ontology can be used by various Bioinformatics researchers from one single site. This site will host mirrors of Protein Databases along with BIODB and have tools on Similarity Searching.


A servo hydraulic driving mechanism was designed using servo-tube control principle, this mechanism can move continuously and position accurately. The three-dimensional flow field of the drive cylinder is calculated and analyzed. The results indicate that the driving mechanism can effectively control the differential pressure of the system by changing the gap of the variable throttle orifice, the diameter of servo-tube is as small as possible. When the gap of the variable throttle orifice is less than a certain millimeter, the control effect is more obvious.

Summary : Tuberculous peritonitis usually presents insidiously. Two cases of peritoneal tuber-culosis presenting as acute peritonitis are reported. Introduction Tuberculous peritonitis is the most ususual form of abdominal tuberculosis. Bhansali (1972) reported 19 cases in a series of 300 cases of abdominal tuberculosis—an incidence of 6.3%. Tuberculous peritonitis accounts for 1.5% of all reported cases of tuberculosis (Vyravanthan & Jeyarajah, 1980). The onset is usually insidious and majority of the cases present with chronic abdominal symptoms. Presentation is sometimes acute—the onset resembling acute peritonitis so closely that the abdomen is opened (Rains & Ritchie, 1984). We have encountered 2 cases of tuberculous peritonitis which presented as an acute abdomen and the diagnosis was revealed at laparotomy. Case Reports Case 1. A 20 year old woman presented with abdominal pain, vomiting and diarrhoea for 2 weeks, associated with fever. She looked ill and was dehydrated. Abdomen was distended with generalised guarding and tenderness. X-rays revealed dilated loops of small intestine with air-fluid levels. A clinical diagnosis of acute peritonitis due to enteric perforation was entertained. Laparotomy, however, revealed ascites and multiple peritoneal tubercles. The intestines were normal and no perforation was seen. Ascitic fluid was removed, peritoneal biopsy performed and abdomen was closed without drainage. Histopathological examina-tion revealed tuberculosis.


The potentiality of Ru-based catalysts for soot oxidation by O2 in fluidized bed reactor has been conducted with temperature programmed reaction (TPR) technique. Compared to Pt/SiO2, Ru/SiO2 exhibited a higher activity in fixed bed reactor. The catalytic activity increased further after other metal oxides loading as second carrier. Among the Ru/MOx/SiO2 (M=Al, Zr, Ti), Ru/TiO2/SiO2 showed the highest activity and its T50 decreased to 435°C, which was 83°C lower than Ru/SiO2. Two types of active sites, RuxTi(1-x)O2 and RuOx, have been identified on the surface of Ru/TiO2/SiO2. Low temperature calcination for Ru/TiO2/SiO2 produced the well-dispersed active sites and benefited the soot oxidation. Compared with fixed bed reactor, Ru-based catalysts are capable of lowering considerably soot combustion temperature in fluidized bed reactor. T50 of the soot oxidation reaction over Ru/TiO2/SiO2 decreased to 389°C. The increase in soot oxidation efficiency at low temperature active sites in the fluidized bed reactor is attributed to the easier migration of activated oxygen species between gas and solid since fluidization improved mass transfer.


The parameters of In0.3Ga0.7As PV cell applied in laser wireless power transmission (LWPT) system dependence on temperature was investigated at a temperature range of 5-90°C under 100mW/cm2 laser intensity with 1070nm wavelength. The pollination algorithm method was used to extract parameters, viz., photocurrent, series and shunt resistance, reverse saturation current, and ideality factor from the I-V curves at each temperature point. The results show that the short circuit current decrease exponentially with temperature increasing, which is obviously different from the condition with solar irradiation. As temperature increases, the conversion efficiency and the open circuit voltage decreases linearly at the rate of 0.095%/°C and 1.89mV/°C, respectively. In addition, the dependence of series and shunt resistance, ideality factor, and fill factor on temperature was also analyzed. This research gives us a new understanding of PV cells under laser irradiation condition, also provides a direction for manufacturing the cells used in LWPT system.The parameters of In0.3Ga0.7As PV cell applied in laser wireless power transmission (LWPT) system dependence on temperature was investigated at a temperature range of 5-90°C under 100mW/cm2 laser intensity with 1070nm wavelength.

AT the time when my first observations on the disease which has been named Angina Pectoris*, were communicated to the public, the affection was by no means so well understood, nor the morbid changes of structure on which it appears to depend so thoroughly investigated and ascertained as they have since been. Many zealous and diligent inquirers have communioated to the medical world the result of their observations on this subject; but the learned and truly didactic work of Dr. Parry of Bath, has concentrated into one luminous point Of


Plastic food packaging materials currently in use are hardly recyclable and very often post consume plastic packaging is directed to incineration or landfill. Use of bio-recyclable plastic will have positive effect on environment, and is gaining importance in particular for the production of active packaging, where a longer shelf-life of the packed food, coupled with improved sustainability can justify the higher cost of biodegradable polymers versus current petro based polymers used in packaging. Among other biodegradable polymers polylactic acid (PLA) has attracted researcher and industries attention for the production of plastic food packaging. In the present contribute we report a study to evaluate the degradability in compost of some representative examples of materials prepared with PLA and chitin nano-fibrils (NC). Since blending a biodegradable polymer with an active compound might hinder the compost ability of the materials produced, it is important to perform test of degradability on innovative materials even if based on biobased and biodegradable components. As well the production of bio-based, biodegradable materials when based on innovative processes, may present several steps that may have a negative effect on sustainability being not optimised in yield, energy consumption and proper valorization of each stream generated in the process. A life cycle assessment study is very important to spot the critical steps in the process and propose corrective actions in the production cycle in order to make the final material more sustainable. The materials based on PLA and NC passed the test of disintegration in compost, evidencing no toxicity on germination of cress seeds. The process of production of NC fibrils, was mostly affected by the high consume of water, and use of chemicals thus plans for recovery and re-use of the water based buffer will improve the sustainability of the process. The bio-nanocomposites based on PLA and NC have a positive environmental effect due to being based on natural resources and having compost ability as possible end of life scenario.

We have examined the dependence of electrical conductivity on bonding temperature and doping type.


From 1981 to 1992 New Zealand's occupational safety and health (OSH) legislation and administration has undergone a significant transformation. At the beginning of the period the situation can be described as a system of "Government Management", by 1990 a system of "Tripartite Management" had been partially introduced, in 1992 a new system of "Employer Hazard Management" had replaced existing arrangements. How did this transformation occur, why did it occur, and how does it compare with overseas examples? The transformation represents a case of reactionary politics. At the social level, change was a reaction to fears in the community about the dangers associated with the advent in New Zealand of large complex industrial plants, and the introduction of new chemicals. At the institutional level of organised actors, change was the result of reaction against perceived inadequacies in the existing legislative and administrative arrangements, and responses to positions adopted by competing actors. At the individual level change came about as organisations responded to the initiatives of certain individuals. By 1992, the colonial reliance upon overseas policy examples had been replaced with policy initiatives that reflected the level of knowledge amongst government officials, and the dominant forms of OSH management practiced by large New Zealand companies.


Background: Worldwide, caesarean section (CS) is one of the most commonly performed obstetric procedures. Maternal mortality and morbidities associated with repeat caesarean section is an important health problem in global perspective that needs to be addressed. Objectives: To evaluate the complications of repeat caesarean section. Materials and Method: This cross-sectional descriptive study was conducted in the department of Obstetrics & Gynaecology, Rangpur medical college hospital, Rangpur from July '18 to June '20 after acceptance and ethical clearance of the protocol. During data collection total admitted patient were 2123 out of which 446 caesarean section was done among them 100 patients of my study population were selected by fulfilling inclusion and exclusion criteria. After full explanation, informing the details of the purpose of the study informed written consent was obtained from the study subjects/ or her legal gardian. After Meticulous history taking thorough physical examination was done on every patient and available investigations according to the need of management was done in the hospital. Per operative and postoperative complications were noted. Information's were collected in predesigned questionnaire and presented in tabulated form and that was finally was analyzed with the help of computer program SPSS (Statistical Package for Social Science) version 23. Result: Total patient admitted during my data collection were 2123 and of them 446 caesarean sections were done and repeat caesarean sections were 100. The incidence of repeat caesarean section was 22.42%. 35% respondents were between >25-30 years of age. Average gestational age was >36 – 40 weeks. Emergency caesarean section was done in 79% cases and elective in 21% cases. 68% patients had adhesion, 38% had uterine atonicity, 26% had injury to the surrounding structure, placenta previa was found in 7% cases and morbid adhesion of placenta was found in 3% cases. Additional procedures like blood transfusion needed in 34% cases, adhesiolysis performed in 21% cases, ICU admission needed in 16% cases, caesarean hysterectomy performed in 11% cases and B-Lynch suture in 8% cases. Among the postoperative complications wound infection occurred in 20% cases, PPH in 13% cases, UTI in 9% cases, paralytic ileus in 4% cases and postpartum psychosis in 3% cases. Maternal mortality was found in only 3% cases. Conclusion: Repeat caesarean section is associated with increased number of intraoperative and postoperative complications like adhesion, placenta previa, morbid adherent placenta, PPH, wound infection thus increasing maternal morbidity. So, the best way to reduce these morbidity and mortality by reducing primary caesarean section rates by taking judicious decision and indications should be appropriate and C/S should be done by well-trained doctors and specialists in well-equipped centre.


Investigation of the precipitation is considered one of the most important agricultural problem. The evaluation of precipitation anomaly role in this field is too significant. So, more or less precipitation falling in the area, particularly in agriculture pose serious consequences for productivity. Drought forming from the less precipitation falling is the serious danger source not only for agriculture, but also to economy. There were billions of damages on world economy every year as a result of this event, people have had to leave their places of residence. Prediction of this event gives opportunity to reduce half of the inflicted damage. That is why prediction of drought is on the agenda as one of the modern problems. Taking into account the significance of this problem it was implemented the precipitation anomaly and drought prediction for the first time, for the economically important region of Azerbaijan.


This paper considers a special case of the two-dimensional bin-packing problem for identical items. The objective of this work is to maximize the space utilization. The main contribution of the paper is to suggest a new heuristic algorithm keeping in view the existing complexity of racking system for the footwear boxes in the compartments of different sizes for a warehouse. The results show that a significant improvement can be obtained. An economic choice of compartments is also estimated using the criteria for maximizing space utilization. A non-linear mathematical model was presented based on the constraints of racking dynamics.


To the editor, Melkersson-Rosenthal syndrome (MRS) is characterized by the triad of persistent or recurrent orofacial edema, relapsing facial paralysis and fissured tongue. Its most consistent clinical symptom is recurrent orofacial or lip swelling. Onequarter of MRS patients exhibit the classic triad1. The classical histopathological finding is noncaseating epithelioid granulomas. However, absence of these does not exclude the diagnosis. MRS, which has an unknown aetiology, affects primarily young adults. To date, considerable amount of cases of MRS coexistent with psoriasis have been described in the literature2-5. In the light of the relevant literature and the case presented here, we discuss the possible association between or coincidence of psoriasis and MRS. A 49-year-old male presented with a 13-year history of progressive and persistent painless swelling of the upper and lower lips. He also gave a history of asymptomatic eruption on his scalp, face, trunk and upper extremities for several months. He had been treated with oral corticosteroids for recurrent lower motor neuron type facial palsy in the preceding four years. The patient was an otherwise healthy man. He did not have any respiratory, gastrointestinal and neurological symptoms. There was no family history of similar complaints and granulomatous disease such as sarcoidosis or Crohn's disease. On examination, the upper and lower lips and, prominently, the right side of the face were swollen (Figure 1a). Erythematous papulosquamous eruption was noted on his scalp, face, trunk and upper extremities (Figure 2a, 2b). There was fissured tongue on oral examination (Figure 1b). Specimens obtained by incisional biopsy which was performed on the lower lip did not reveal typical granuloma. However, serial sections showed loose granuloma-like histiocyte accumulations (Figure 3a, 3b). The findings of routine blood and stool examination were normal. Chest X-ray did not reveal hilar or mediastinal node enlargement. On the basis of clinical findings, the diagnosis of MRS was made. The biopsy specimen from a plaque lesion on the scalp presented a psoriasiform lesion with parakeratosis and neutrophils in parakeratotic scale. Dermis showed dilated capillaries (Figure 3c). Periodic acid-Schiff staining did not show any fungal organism. The histopathological findings were consistent with psoriasis. Since the diagnosis of MRS is based on typical clinical features, histological evidence is not essential. Noncaseating granulomas in histopathological examination support the diagnosis. The pathologic examination of our patient showed chronic inflammation with focal histiocyte accumulation. He presented with the full triad of the syndrome. The fissured


There is a growing need to effectively address the sexual and reproductive health needs of adolescents in Nigeria. This is an exploratory study that examined the opinions and preferences of parents in Lagos Mainland regarding approval, timing and content of sexuality education in schools. Using a list of sexuality education topics, parents were asked to examine which topics they believed should be taught in schools. Majority of parents were found to have reasonably positive attitudes toward teaching sexuality education in schools and the contents of sexuality education classes. In addition, most parents showed more approval for topics that taught about the transmission of sexually-transmitted infections as well as encouraged abstinence among students.


Motion plays an important role in the acceptance process of ideological and political education. Educator's emotion affects the understanding of the recipient. The emotion of recipient directly determines the cognition of ideological and political education of the recipient. Education content and emotion factors in education forms can strengthen or reduce the realization of acceptance of ideological and political education.


To date, much of the research on the interaction between work and family has focused on single countries or comparative studies on OECD countries. The goal of this paper is to demonstrate the feasibility of bringing a truly global perspective to comparative research on work, family, and community questions. We conducted an examination of extended‐hour work in four countries in Latin America, Africa, and Asia. This paper highlights two facts: first, the feasibility of using existing data sources to carry out comparative research on a more diverse range of countries than has generally been conducted to date, and second, the importance of conducting such analyses because of the critical insights that are gained for improving public policies and services.

Internet access is so easy that every level of society can access information from the website. If internet access is used positively, it will produce positive things for its users as well. Such as the facilities provided by the management of SMK Al-Mahrusiyah Lirboyo. Students, especially in the Computer and Network Engineering (TKJ) department, get facilities such as PCs in the lab or laptops along with internet access during productive learning hours. In its application in schools, students who are given laptop facilities and internet access do not always use it for learning. Questionnaire data showed that there were other things that were opened, including 37.7% of respondents finding and trying hacking tutorials, 35.8% playing social media, and 34% streaming movies. For this reason, a firewall is needed that restricts students' access to it. The firewall will be formulated with a script on the MikroTik router through the WinBox. The results of firewall tests using a combination of filters and Raw successfully blocked access to social media websites, streaming movies, and anime. The client cannot access and the display in the client browser displays continuous loading. Testing firewalls to ward off DoS attacks was also successful. When tested, LOIC did not send a single request packet and when the CPU resource was checked, the resource was only 1%. The use of firewalls with MikroTik routers is effective in limiting students' access to other things outside of learning. With this, it is hoped that students can better utilize facilities for learning.


The effect of different loads on the high-temperature wear behavior of 5Cr5Mo2V steel at 700 °C was investigated. Wear morphologies, oxide compositions and matrix evolution were studied. The results showed that the wear rate increased with an increased test load, and the wear mechanism transformed from abrasive-oxidative wear to adhesive-oxidative wear. The relation between a delaminated oxide layer and cracks in the matrix were investigated. The exfoliation of carbides and displacement difference between the matrix and carbides caused a crack initiation. The wear rate strongly related to carbides, and coarse M6C carbides with poor holding power led to a high wear rate. Besides, a diagram of wear characteristics under different loads was suggested in this work.


Purpose – The purpose of this paper is to examine why and when followers of transformational leaders exhibit increased affective organizational commitment. Particularly, the authors examined the role played by perceived organizational support (POS) and supervisor's organizational embodiment (SOE), i.e. a perception concerning the extent to which employees identify their supervisor with the organization, in this relationship. Design/methodology/approach – In total, 287 employees of a water producer organization responded to a questionnaire. Findings – The results show that, when employees strongly identify their supervisor with the organization, transformational leadership is positively related to POS, with positive consequences in terms of emotional attachment to this organization. In contrast, when the supervisor is not identified to the organization, his/her transformational leadership does not extend to POS and, finally, to affective organizational commitment. Practical implications – The findings sugg...


This paper investigates an integrated optimization problem of routing design and departure time determination of customized buses based on demand-responsive service. The problem aims to optimize both a set of customized routes and the departure time of each route based on a set of reserved trip requests. A mixed integer programming model is formulated to address the problem. The model aims to minimize the sum of the operator cost of the bus company and the total travel cost of passengers so that the buses can be efficiently used to provide high-quality services to passengers. To solve the model, a departure time determination method based on a time window backpropagation process is first proposed to optimize the bus departure time for a given route. Then a variable neighborhood search (VNS) algorithm with customized operators is designed to generate the optimized routes. Finally, different numerical tests are conducted to verify the effectiveness of the proposed model and the algorithm, then the sensitivity analysis on key parameters follows.


The in vitro effects of low energy He-Ne laser on the motility, velocity, straight-ness and amplitude of lateral head displacement of human sperm were measured by using automated semen analyzer ni a total of 33 ejaculates. No significant difference could be found in all sperm characteristics between semen samples untreated and treated for different irradiation duration (15 sec, 30 sec, 2 min, 4 min and 8 min). There was also no significant change with respect to the percentage of normal forms. The results of out study were contradictory to previous reports which showed a stimu-latory effect of low energy laser on sperm motility or velocity. (J Urol R.O.C., 2:472-476, 1991)


In Zea mays L. (cv. XL 72 A) leaves sulphur deficiency caused reduction of soluble protein and chlorophyll contents, whereas ATP sulphurylase (EC 18.104.22.168) and O-acetylserine sulphydrylase (EC 220.127.116.11) activities increased with the increasing of S-deprivation time. The two enzymes exhibited the maximum activity after 5 d (ATP sulphurylase) and 3 d (O-acetylserine sulphydrylase) from the beginning of deprivation period. The activities were differently distributed between mesophyll protoplasts and bundle sheath strands. The results suggest that the activity of the two enzymes may be induced sequentially and differently regulated in the two types of cells.


At present,the internet pornographic text is in varied forms and changeful, although it is prohibited ever. It severely harms people's mental and physical health development and social stability. There are IP-based,keyword-based and intelligent content analysis filtering system against it today. But they are difficult to deal with manifestations of diversity, changeful, and increasingly concealed porn. In this paper, a in-depth research has done for the appeared characteristics of such undesirable information on our statistical analysis. And based on this characteristics, a new text pre-processing algorithm PA-PTCI is proposed, and a effective model combined with content filtering technology to the current text information filtering pornography problem is designed. The experimental result shows the PA-PTCI algorithm and the model of Chinese pornography text filtering are quite effective.


Durum wheat (Triticum turgidum, 2n = 4x = AABB) includes several subspecies with differential characteristics in their root system architecture (RSA). Subspecies durum has longer and more vertical roots, while subspecies turgidum has smaller and shallower roots. The homeologous genes TtDro1A and TtDro1B of both subspecies have been identified and found to differ in their sizes, sequences and the proteins they encode. To determine whether there is a relationship between the level of expression of these two genes and the angle adopted by the roots of durum wheat seedlings, their expressions has been studied by RT-qPCR, both in the primary seminal root and in the other seminal roots. The results of the analyses showed that the TtDro1A gene is expressed 1.4 times more in the primary seminal root than in the other seminal roots. Furthermore, this gene is expressed 2.49 to 8.76 times more than TtDro1B depending on root type (primary or seminal) and subspecies. There are positive correlations between the expression ratio of both genes (TtDro1A/TtDro1B) and the mean of all root angles, the most vertical root angle and the most horizontal root angle of the seedlings. The higher the expression of TtDro1B gene, the lower the root growth angles.

File systems play an essential role in modern society for managing precious data. To meet diverse needs, they often support many configuration parameters. Such flexibility comes at the price of additional complexity which can lead to subtle configuration-related issues. To address this challenge, we study the configuration-related issues of two major file systems (i.e., Ext4 and XFS) in depth, and identify a prevalent pattern called multilevel configuration dependencies. Based on the study, we build an extensible tool called CONFD to extract the dependencies automatically, and create six plugins to address different configuration-related issues. Our experiments on Ext4 and XFS show that CONFD can extract more than 150 configuration dependencies for the file systems with a low false positive rate. Moreover, the dependency-guided plugins can identify various configuration issues (e.g., mishandling of configurations, regression test failures induced by valid configurations).


Visual query systems (VQSs) are query systems for databases that use visual representations to depict the domain of interest and express related requests. VQSs can be seen as an evolution of query languages adopted into database management systems; they are designed to improve the effectiveness of the human?computer communication. Thus, their most important features are those that determine the nature of the human?computer dialogue. In order to survey and compare existing VQSs used for querying traditional databases, we first introduce a classification based on such features, namely the adopted visual representations and the interaction strategies. We then identify several user types and match the VQS classes against them, in order to understand which kind of system may be suitable for each kind of user. We also report usability experiments which support our claims. Finally, some of the most important open problems in the VQS area are described.


In this study, a parametrized output feedback dynamic sliding mode controller is proposed and the internal stability, BIBO stability, and external disturbance rejection problem of a generalized plant is studied. The proposed controller is described by a a solution of Bezout equation and is parametrized by a Youla's free parameter on RH/sub /spl infin//. It is shown that by this controller, the sliding mode is achieved in finite time, and thereafter, the ideal sliding mode controller stabilizes the generalized plant in the sense that internal stability is assured. Also, the model matching problem is formulated for a generalized plant, and the difference between linear dynamic controller and sliding mode controller is highlighted. The two simulation results show the strength of this method.


This study investigates the influence of technological innovative capabilities (TICs) on firm performance (FP) in the IT sector, with strategic agility as a moderator variable. This paper analyzes the TICs at the firm level in the service sector using the functional approach. An online structured questionnaire was adapted and refined to collect the required information on the influence of TICs dimensions on FP in the IT sector to achieve the objectives. The unit of analysis consists of top management staff and heads of departments from IT firms in Amman, Jordan. A sample of 67 IT firms was selected, and 300 questionnaires were distributed. A total number of returned responses was 223, producing a 74% response rate. Structural equation modeling was used to test the hypotheses. The revealed findings show that learning capability, marketing capability, organizational capability, and strategic planning capability had a significant influence on FP, whereas resource allocation capability was not significant. In addition, multiple hierarchical regression was used to test the moderating effect of strategic agility on the relationship between TICs and FP. Revealed results of the overall model to examine the moderating effect show that strategic agility is not significant in moderating the relationship between TICs dimensions and FP.


We developed an interactive three-dimensional (3D) ultrasound (US) workstation that is inexpensive and suitable for use in research and clinical environments. Our personal computer–based system produces 3D volumes by acquiring a series of 2D images from a commercial ultrasound scanner, spatially registering the images using an electromagnetic position sensor, and reconstructing the data into a regular 3D Cartesian volume. The 3D US system uses an imaging board based on the Texas Instruments TMS320C80 Multimedia Video Processor (MVP), a fully programmable mediaprocessor that includes multiple processing units on a single chip. We developed efficient volume reconstruction and visualization algorithms for the MVP that allow our 3D US system to provide the same immediate feedback as current 2D US technologies with the added advantage of presenting information in three dimensions. For example, for acquired sequences of 512 3 512 US images, volumes can be reconstructed using six degree-of-freedom position measurements at 11.4 frames/s. A modified reconstruction algorithm that performs incremental reconstruction was developed to enable real-time volume reconstruction and visualization during acquisition and operates at 12.5 frames/s. US volumes can be rendered via shear-warp factorization and maximum intensity projection (MIP) at 10 frames/s for 128 3 128 3 128 volumes and 1.45 frames/s for 255 3 255 3 255 volumes. © 1998 John Wiley & Sons, Inc.

The vast increase in the amount of imagery to be exploited has led the intelligence community to look for techniques to increase the efficiency of the image analysts, who are also dwindling in number. One approach has been automatic target recognition (ATR). Although ATR has made considerable advancement in recent years it is not yet at the point where automatic recognition is sufficiently robust for general operational use. One hybrid approach being investigated is computer assisted ATR using man in the loop interactive exploitation. The Interactive Imagery Exploitation (INIMEX) program sponsored by DARPA ISO is one approach to the problem. INIMEX is combining ATR algorithms from DARPA's MSTAR and Image Understanding (IU) programs with a new Human Computer Interface (HCI) paradigm in an attempt to greatly improve exploitation throughput. The HCI is based on the Pad++ Zoomable User Interface (ZUI) software developed by NYU, the University of New Mexico, the University of Maryland, and UCSD. Pad++ uses zooming as a primary method of manipulating data, which gives the exploiter a 3rd dimension to work in as opposed to the 2 dimensions in the past. However, navigation principally involves familiar 2-dimensional concepts. The Pad++ space is conceptually infinite in 3 dimensions and is ideally suited for implementing the electronic sandbox concept. Using this concept, multiple data types are organized in a layered format in which all data types are co-registered. Lockheed Martin Astronautics is currently implementing a system that incorporates traditional Electronic Light Table (ELT) functions within a ZUI. MSTAR ATR and IU functions, such as target recognition and temporal analysis, are integrated into the system using Pad++'s lens concept. A critical aspect of the program is user involvement. A spiral development approach is being taken with periodic "Mockups" being delivered for evaluation by image analysts and feedback to the developers. INIMEX will be provided to an operational organization for a period of time for evaluation and feedback.


Colorization is not a guaranteed, but a feasible mapping between intensity and chrominance values. This paper presents a colorization system that draws inspiration from recent developments in deep learning and makes use of both locally and globally relevant data. One such property is the rarity of each color category on the quantized plane. The denoising model contains hybrid approach with cluster normalization through U-Net deep learning construction of framework. These are built on the basic U-Net design for segmentation. To eliminate gaussian noise in digital images, this article has developed and tested a generic deep learning denoising model. PSNR and MSE are used as performance measures for comparison purposes.


This paper is concerned with those villages of medieval England which have failed to survive as centres of population. As flourishing as their neighbours in the twelfth and thirteenth centuries, they appear now only as a complex of earthworks in open countryside; some may have a farm-house or a manor-house near them which will bear the name of the village. Others lack even this memorial. Yet these abandoned sites have their place in economic history: for each represents a landowner pursuing his advantage to the point of destroying a farming community, either inside or outside the letter of the law. They have their place in the history of land-use also: for each was the victim of conversion from arable to pasture and from the open-field landscape to the enclosed sheep-run. In the study of settlement they indicate an appreciable number of villages which must be added to the Ordnance Map if we wish to see the settlement pattern of the mid-fourteenth century in its completeness. From then until the industrial revolution the number of nucleated units seems on balance to have decreased. In these sites we see the layout of the medieval village unencumbered by more recent acretions. Many modern English villages, which are still very much alive as communities, show that the area they occupy is less than of earlier centuries, and the earthworks of former cottages and gardens flank the edges of the village. But the shrunken village is a separate study, and we are here concerned with the village site which has shrunk to a pair of cottages, a farm, or a field-lane. The material on which I have drawn includes the list of 146 Lincolnshire sites made by the late Canon Foster l in 1924, the excavation of a Berkshire


Presents a focusing strategy for the 3-D reconstruction of urban scenes from aerial stereo pairs. It consists in segmenting the scene into above-ground objects (buildings or vegetation), and it relies on 3-D and radiometric analyses. The classification is able to cope with extended above-ground, adjacent objects, slopes, and it is robust to image and scene variability.


Minority game is a simulation of a zero-sum game, which has a similar structure to that of a real world market like a currency exchange market. We discuss a way to implement the game and provide a simulation environment with agents that can use various types of strategies to make decisions including genetic algorithms, statistics, and cooperative strategies. The goal of this simulation study is to find the effective strategies for winning the zero-sum game. Results show that both honesty and dishonesty can lead to a player's success depending on the characteristics of the majority of players.


New polythioesters have been obtained in the interfacial polycondensation of 4,4′-di(mercaptomethyl)benzophenone with terephthaloyl, isophthaloyl and phthaloyl chlorides. The reactions were carried out at room temperature with the use of 10% excess of acid chloride per mole of mercaptan with vigorous stirring (2000 rpm). The organic phase was composed of benzene and hexane in equal volumes and the ratio of this mixture to water also was 1:1. The structure of the polythioesters was determined from elementary analysis and the infrared spectra. The molecular weight was not determined because of the very low solubility of polythioesters. Some thermal, mechanical, and electrical properties of the products have been determined. Products of dimercaptan with the terephthaloyl and isophthaloyl chlorides show the best properties.


Sixty female subjects were given false information that they had done either well or poorly on a task purported to measure creativity, or were given no performance information. All subjects then worked on an insoluble task either alone or while being observed by the experimenter. Among subjects who had supposedly done well on the first task, persistence on the second was greater when they were observed than when they worked in isolation. Among subjects who had supposedly done poorly on the first task, persistence on the second task did not vary with observation or isolation. The results are explained in terms of a two-process model of social facilitation/inhibition of performance following success and failure experiences.

In this paper, a frequent itemsets mining algorithm of data stream based on concept lattice and sliding window is presented. This algorithm mines frequent concepts for new inflowing basic window in batches in a sliding window and generates concept lattice Hasse diagram. With introduction into small support degreeand error factorto do the pruning operations for non-frequent concept node, each connection point in the Hasse diagram contains the information of frequent itemsets and support degree. As the generation of Hasse diagram in the new basic windows, we integrate concept lattice vertically with the generated Hasse diagram and sliding window, and ultimately output all frequent itemsets through scanning all the graph nodes of Hasse diagram graph. The experimental results show that the proposed algorithm has a good performance. DOI: http://dx.doi.org/10.11591/telkomnika.v11i8.3140


In this paper problem of 3D bone reconstruction starting from 2D conventional x-ray projections has been addressed in the pursuit of two major goals. The first goal consists of the 3D reconstruction of a bone and the recovery of some anomalies. The last goal is the simulation of the behaviour of the bone under orthopedic operations. Our approach is based on back-lighting projections, polygon mesh and b-spline interpolation and has been implemented in the AutoCad software environment.

oss of urinary control can have a sigmficant impact on the psychological and social well-being of the affected individual. Research has conL centrated on the prevalence, etiology, and management of urinary incontinence, but relatively little is known about the effects of this chronic condition on psychosocial functioning in daily life. This article reviews the literature related to psychosoaal impact of urinary incontinence in the communitydwelling adult population. The focus is on the individual with incontinence who is otherwise healthy, mentally intact, and residing independently in the community. Issues related to the definition and measurement of psychosocial impact are discussed. Relevant research findings are presented on the type and degree of psychosocial effects resulting from incontinence, differences in impact related to the underlying etiology of incontinence, and the relationship of psychosocial impact to severity measures of urinary incontinence. Recommendations for future research are also proposed.


In this study, it is intended to increase the clas- sification accuracy results of malignant lymphoma images by evaluating spatial relations. As a first step, convolutional neural network (CNN) based features are extracted in the original RGB color space of digital histopathalogical images. Classification models of each feature vectors are obtained by employing CNN, support vector machines (SVM) and random forest (RF) methods. For comparison purposes, the classification accuracy results obtained from supervised learning methods are presented in the experimental results section.

All of these treatment methods should be fully used to rationally and economically develop the municipal solid waste resource and the three-level management system is proved to be efficient in municipal solid waste treatment in Beijing.


BACKGROUND: As a result of political instability and poor macroeconomic policies from 1972-86, Uganda underwent a dramatic reversal of the agricultural and structural transformation process it had achieved in the 1960s. By the time Uganda opened up again to the international community after the fall of Amin, its economy was on the verge of total collapse, and it had suffered a near total breakdown of agricultural research, seed multiplication, output markets, input distribution networks, and extension services. Virtually no new agricultural methods or technologies were introduced between the late 1960s and early 1990s. Worse, many productivity


The invention discloses a portable flight parameter data calibration method and device. Firstly, a clamp is installed on a measured rotating body, a measuring unit is installed on the clamp, then a first control and display unit is connected with a measuring unit through a cable, and a second control and display unit is connected with the first control and display unit through a cable. A power source of the first control and display unit and a power source of the second control and display unit are connected for the first control and display unit and the second control and display unit to work. The measured rotating body is controlled to rotate or move, and the moving angle of the measured rotating body is displayed synchronously on two displayers. The portable flight parameter data calibration method and device have the advantages that the calibration work of a flight parameter channel can be completed simply through two persons, and due to the fact that labor is saved, the calibration and preparation time is shortened and information transmission errors of many people in the cooperation process can be avoided, the calibration accuracy and the calibration efficiency can be greatly improved.


Despite the discovery that CA125 and other serum markers increase before the clinical onset of ovarian cancer, it has proven surprisingly difficult to devise a successful screening program for asymptomatic women with ovarian cancer. In this issue of the Journal, Anderson et al. ( 1 ) take a valuable step toward the successful design of such a screening program by demonstrating one reason why screening regimens that are based on markers, or panels of markers, can fail. They found that blood levels of CA125, human epididymis protein 4, mesothelin, and three other promising markers did not increase early enough. The markers typically gave a strong signal not more than a year in advance of the symptoms that led to diagnosis, and by this time, many of the cancers had reached an advanced stage of malignancy. The results of Anderson et al. are not the last word in serum markers or in combinations of markers. Serum markers likely will form a key element in any screening regimen, with the lead time and other parameters of each marker or combination of markers being taken into account. The careful evaluation technique applied in the current study fi ts into a staged approach necessary for testing performance of early markers of disease ( 2 ). Candidate markers emerge from less expensive studies, typically clinical investigations that compare patients with newly diagnosed stage I cancers with women without malignancy. The most promising candidates from the postdiagnosis studies warrant the next step of more realistic comparisons, which use blinded assays of blood that was drawn a year or two before the diagnosis. Unfortunately, many of those biomarkers have a rapid increase in serum concentration late in the course of cancer development or progression, and most will turn out to have little predictive value before symptoms would have led to diagnosis. Markers that prove to be predictive in samples that were collected a year or so before diagnosis then warrant assessment at multiple intervals before diagnosis to trace their time course. Such a retrospective investigation of case patients and control subjects nested in a longitudinal study with serial banked samples, the design used by Anderson et al., offers the second-best evidence of likely performance in a screening program. Only the time-consuming, expensive, and demanding randomized clinical trial can reveal whether an early detection program that includes the biomarkers can save lives. Current randomized trials are testing the value of different screening programs that are built on combinations of CA125, ultrasound, and risk factor data (such as family history and age). After four rounds of screening 34 261 postmenopausal women for ovarian cancer with both CA125 and ultrasound, investigators of the large US screening trial observed that the predictive value of a positive screen was quite low, approximately 1% ( 3 ). Of the 60 screen-detected cancers, 72% had already advanced to at least stage III. In addition, of every 20 women who underwent surgery after a positive screen, just one had cancer. Furthermore, in the UK trial with a slightly different design, positive predictive values from the fi rst round of screening were higher, 35% in the 50 078 women whose risk was assessed with CA125 and risk factor data, followed by ultrasound only if indicated, and 3% in the 50 639 women screened fi rst with ultrasound ( 4 ). The effects on mortality in both trials remain to be determined. We confront daunting arithmetic to avert premature death from ovarian cancer. In the United States, incidence amounts to 13 cases of ovarian cancer per 100 000 woman-years, proverbial needles in the haystack ( 5 ). Incidence of ovarian cancer increases with age, to 57 cases per 100 000 women aged 75 – 79 years. Family history, low parity, and more ovulations over a lifetime further predict risk, with the strongest but least common predictor being a mutation in BRCA1 or BRCA2 genes. Among women with higher baseline risks, the predictive value of a positive serum test tends to increase. One can boost performance of an overall screening program by targeting higher-risk subgroups of women for screening or by explicitly combining personal history, host genetics, and levels of serum markers in one prediction model. With advances in understanding etiology, we will also improve the risk models that are useful for screening programs. We can also improve the performance of a program that is based on a panel of biomarkers by changing what we do after we fi nd a suspicious biomarker result. That is, if highly specifi c imaging, ideally better than currently offered by ultrasound, followed a suspicious value for a serum marker, then fewer women would undergo surgery. Similarly, less invasive surgery might further reduce harmful side effects. For now, we do not have a proven biomarker, panel of biomarkers, or overall screening program that works well. The current report, with its sobering implications, brings us closer to understanding the crucial elements in designing any effective early detection program for ovarian cancer.


The article presents a graph-based spatial analysis toolset ("decoding spaces"components) which we have recently developed as an extension of the visual scripting language Grasshopper3D for Rhino. These tools directly integrate spatial analysis methods into CAD design software which can have a signifi cant effect on current design workfl ows. However,grasshopper doesn't only enable the results of analyses to be used in the standard Rhino modelling environment. It also makes it possible to integrate spatial analysis into a parametric design approach as discussed in this paper. The functionality of this toolset is demonstrated using a simple urban design scenario where we introduce the idea of parametric patterns based on graph-measures.


Sarcoma represents a highly heterogeneous group of tumours. We report here the first unbiased and systematic search for gene fusions combined with unsupervised expression analysis of a series of 184 small round cell sarcomas. Fusion genes were detected in 59% of samples, with half of them being observed recurrently. We identified biologically homogeneous groups of tumours such as the CIC‐fused (to DUX4, FOXO4 or NUTM1) and BCOR‐rearranged (BCOR–CCNB3, BCOR–MAML3, ZC3H7B–BCOR, and BCOR internal duplication) tumour groups. VGLL2‐fused tumours represented a more biologically and pathologically heterogeneous group. This study also refined the characteristics of some entities such as EWSR1–PATZ1 spindle cell sarcoma or FUS–NFATC2 bone tumours that are different from EWSR1–NFATC2 tumours and transcriptionally resemble CIC‐fused tumour entities. We also describe a completely novel group of epithelioid and spindle‐cell rhabdomyosarcomas characterized by EWSR1– or FUS–TFCP2 fusions. Finally, expression data identified some potentially new therapeutic targets or pathways. Copyright © 2018 Pathological Society of Great Britain and Ireland. Published by John Wiley & Sons, Ltd.


Serum lactate dehydrogenase has been extensively studied in hypertensive disorders of pregnancy. However, to date, its clinical usefulness in the field remains unknown. The present meta‐analysis has been designed to evaluate differences in serum LDH values among patients with hypertensive disorders of pregnancy and to help determine its diagnostic accuracy as well its predictive accuracy in determining adverse pregnancy outcomes.


The growing burden of chronic disease, including CVD, is escalating both health care spending and morbidity and mortality rates. 1 CVD is the leading cause of morbidity and mortality for men and women, causing 34% of all deaths in Canada. 2 By causing premature death, CVD has a significant impact on the quality of life of those afflicted by the disease, while resulting in negative economic and social consequences, particularly in SA seniors. 3 The risk and burden of heart disease in SA immigrants living in western societies is higher than in non-immigrants. 3 This is a concerning trend considering that SA immigrants are the fastest growing group of Canadian ethnic immigrants. 4 Given the demographic shift in Canada's immigrant population, HCPs must respond to the increased prevalence of CVD in Canadian SA seniors in order to effectively meet the health care needs of this population. Historically, CVD prevention programs in Canada have focused on non-immigrants, with little research on ethnic differences in cardiovascular health and ethnically tailored prevention strategies. 3, 5 As a result, the primary role of HCPs working with SA seniors is to increase the senior's awareness of CVD and associated risk factors in hopes that this may provide the incentive to make healthy lifestyle changes. 6 HCPs who assume active roles in reducing the risk of CVD in vulnerable populations can positively influence overall morbidity and mortality rates. 7 CVD is growing out of proportion in the SA seniors' population due to a lack of knowledge and awareness in self-care management strategies, resulting in poor lifestyle choices. This results in a significant increase in modifiable risk factors, such as blood pressure and cholesterol. In order to better manage their disease and prevent rapid deterioration of their health, the SA senior population requires prompt, quality health information. The current health care delivery model is inefficient as seniors struggle with barriers such as accessibility and timely interventions.  Hence, telehealth is a technology solution to reduce the risk of CVD among the seniors. It is the delivery of health care services to clients, such as the frail senior with mobility concerns, in the privacy of their home, to maintain or restore their health, improve their independence, and reduce disability or exacerbation of illness.


In the previous study, Penicillium sp. ID10-T065 has been mutated using ultraviolet (UV), ethyl methyl sulfonate (EMS) and the combination of UV-EMS to increase Beta-glucosidase (bgl) activity. There were three mutants selected, UV13 (UV mutant), EM31 (EMS mutant), and UM23 (UV-EMS mutant). This study examined the mutations in the bgl gene encoding (bgl1) as well as sequence differences between mutants and wild-type of Penicillium sp. ID10-T065. The gene analysis was performed by PCR amplification and sequencing of the bgl1 gene. The results of bgl1 gene sequences (600 bp) from mutants were aligned with the wild-type, it was discovered that there were base alterations from position 2025 to 2050. Mutant UV13 showed the highest base alterations (7 bases) which occurred at position 2027 (T→C); 2036 (T→G); 2040 (T→G); 2047 (G→C); and 2048-2050 (TTG→GGA). Mutant EM31 showed alterations in five bases at positions 2034 (G→A), 2036 (T→G), 2037 (G→C), 2044 (G→C), and 2047 (G→T). Mutant UM23 showed two base alterations at position 2025 (T→A) and 2037 (G→C). UV irradiation and EMS mutation resulted in transition and transversion DNA, whereas the combination of UV-EMS mutation resulted in transversion mutations. Base alterations in UV13 and EM31 mutants, causing missense and silent mutation, while in UM23 mutant only silent mutations occur. The bgl1 gene analysis showed that mutation using UV light was more effective than using EMS or a combination of UV-EMS in Penicillium sp. ID10-T065.


Well done to the authors on tackling a difficult topic and presenting the research results in a way that may provide an indication of how Indigenous public policy related to physical activity could move forward in Australia. I think the findings in this paper are a significant addition to the current evidence base and it is important that they are widely disseminated publicly and in the academic literature. However, I do have some major reservations about the current structure and content of the paper. I strongly encourage the authors to address these concerns so that these important research findings can be published.


The mycelial growth condition of Ch10 strain,apathogenic fungus of leaf spot disease in H.plantaginea,was analyzed by mycelial growth rate and liquid shaking culture methods to study the biological characteristics of Cercospora fungus.The results showed that temperature,pH,medium,different carbon and nitrogen sources have the significant effect on mycelial growth of Ch10 strain,and the optimum temperature,pH,carbon and nitrogen sources are 25℃,6,lactose,maltose,yeast extract and potassium nitrate.The mycelial growth of Ch10 strain cultured on MEA medium is slightly faster than other media but its maximum colony diameter is only 2.37 cm after 21 dculture,and the mycelium forms conidia rarely.


Users' QoE (Quality of Experience) in Multi-sensorial, Immersive, Collaborative Environments (MICE) applications is mostly measured by psychometric studies. These studies provide a subjective insight into the performance of such applications. In this paper, we hypothesize that spatial coherence or the lack of it of the embedded virtual objects among users has a correlation to the QoE in MICE. We use Position Discrepancy (PD) to model this lack of spatial coherence in MICE. Based on that, we propose a Hierarchical Position Discrepancy Model (HPDM) that computes PD at multiple levels to derive the application/system-level PD as a measure of performance.; AB@Experimental results on an example task in MICE show that HPDM can objectively quantify the application performance and has a correlation to the psychometric study-based QoE measurements. We envisage HPDM can provide more insight on the MICE application without the need for extensive user study.


To properly answer a question, you must first understand the question. Users typically send more explanations than they need to answer in order to express their question in natural language, which increases the complexity of the question and provides useless side information, which leads to the production of false and unrelated answers and makes it difficult to answer the questions. In this paper, we propose a method for summarizing questions in Persian based on the multilingual pre-trained text-to-text transformer model. To begin, we collected a number of question and question summary pairs from websites for answering religious questions, and after fine-tuning the mT5 model with this dataset, we applied the evaluation criteria of Rouge-1, Rouge-2, and Rouge-L. We examined it using the F-measure and obtained satisfactory results.


We present a multi-channel MAC protocol for ad hoc networks, for nodes equipped with a single half-duplex transceiver, combining the use of OFDMA and CDMA. To ease OFDMA channel management the network is clustered. Channel groups are defined by a resolvable {\em balanced incomplete block design} (BIBD) to minimize interference. Unique CDMA codes are assigned to each cluster. Clusterheads manage and assign channel groups through an extended handshake. Idle nodes that overhear the handshake cooperate to reduce the incidence of the multi-channel hidden- and exposed-terminal problems, and also the near-far problem of CDMA. Simulation results show a significant improvement in average delivery ratio and delay, especially in dense network topologies.


Abstract : This report documents the development of a digital simulation that predicts the mean tracking error of a human performing compensatory tracking with the T-65 anitaircraft gun. Such tracking occurs with the on-carriage operation of anitaircraft guns against maneuvering aircraft. A prior study of the Soviet 23 and 37mm weapon systems provided much of the basis for this current study. Parameters used in this simulation were determined from models generated from field test data and from tracking data generated on a hybrid computer. Correlations were also developed that predict the variance of the tracking error as a function of flight parameters for this weapon system. (Author)


We analyze the internal symmetries and their anomalies in the Kitaev spin-$S$ models. Importantly, these models have a lattice version of a $\mathbb{Z}_2$ 1-form symmetry, denoted by $\mathbb{Z}_2^{[1]}$. There is also an ordinary 0-form $\mathbb{Z}_2^{(x)}\times\mathbb{Z}_2^{(y)}\times\mathbb{Z}_2^T$ symmetry, where $\mathbb{Z}_2^{(x)}\times\mathbb{Z}_2^{(y)}$ are $\pi$ spin rotations around two orthogonal axes, and $\mathbb{Z}_2^T$ is the time reversal symmetry. The anomalies associated with the full $\mathbb{Z}_2^{(x)}\times\mathbb{Z}_2^{(y)}\times\mathbb{Z}_2^T\times\mathbb{Z}_2^{[1]}$ symmetry are classified by $\mathbb{Z}_2^{17}$. We find that for $S\in\mathbb{Z}$ the model is anomaly-free, while for $S\in\mathbb{Z}+\frac{1}{2}$ there is an anomaly purely associated with the 1-form symmetry, but there is no anomaly purely associated with the ordinary symmetry or mixed anomaly between the 0-form and 1-form symmetries. The consequences of these anomalies apply to not only the Kitaev spin-$S$ models, but also any of their perturbed versions, assuming that the perturbations are local and respect the symmetries. If these local perturbations are weak, these consequences apply even if the perturbations break the 1-form symmetry. A notable consequence is that there must be a deconfined fermionic excitation carrying no fractional quantum number under the $\mathbb{Z}_2^{(x)}\times\mathbb{Z}_2^{(y)}\times\mathbb{Z}_2^T$ symmetry if $S\in\mathbb{Z}+\frac{1}{2}$.


For a real non-signdefinite function $B(z)$, $z\in \C$, we investigate the dimension of the space of entire analytical functions square integrable with weight $e^{\pm 2F}$, where the function $F(z)=F(x_1,x_2)$ satisfies the Poisson equation $\D F=B$. The answer is known for the function $B$ with constant sign. We discuss some classes of non-signdefinite positively homogeneous functions $B$, where both infinite and zero dimension may occur. In the former case we present a method of constructing entire functions with prescribed behavior at infinity in different directions. The topic is closely related with the question of the dimension of the zero energy subspace (zero modes) for the Pauli operator.


We describe a 30-year-old woman with a normal appearing coronary artery associated with SLE who suffered myocardial infarction with left ventricular aneurysm and systemic embolization including cerebral infarctions and saddle embolism. The patient was surgically treated with good results. To our knowledge this is the first reported case of systemic embolism due to myocardial infarction occurring in SLE with a normal coronary artery.


Tracking of any object from a video scene becomes more critical not only for security applications but also for analyzing traffic. This system integrates low level image processing as well as high level image processing through online data model and offline data model for more efficiency and robustness. Also this makes the system to handle occlusion conditions and abrupt color intensity variation conditions. This system uses median filtering and blob extraction for moving object detection. The offline model employs high level image processing recognize the moving objects. Here the Kalman filter is used for effective tracking under complex situations.

Paracoccidioidomycosis (PCM) is a deep fungal infection, endemic with considerable morbidity in South America, whose first symptoms can occur in the oral cavity. A 47-year-old male patient, leucoderma, living on the streets, presenting dyspnea, pain during the speech, and dysphagia, was referred for admission to the ICU for suspected COVID-19 infection. The intensive care physician's evaluation revealed a tongue lesion with suspected carcinoma. By dentist investigation, was observed the presence of moriform lesions with high borders delimitation in the tongue. Also, granulomatous ulcers with irregular texture, suggesting moriform stomatitis, the chest tomography revealed diffuse thickening of the bronchial walls, indicating chronic bronchopathy with discrete centrilobular nodules, sometimes confluent. Incisional tongue biopsy associated with lung imaging confirmed the diagnosis of PCM, and the patient was referred to the referral center for the treatment of fungal diseases. The involvement of the oral environment as a region to the appearance of detectable first symptoms of PCM suggests the need for the oral evaluation by a specialist as a diagnostic tool.

The dipole moment of the 4-nitrophenol–tri-n-butylamine (PNP·TBA) adduct of the 1∶1 stoichiometry was studied in tetrachloroethylene, chloroform and 1,2-dibromoethane as a function of temperature. Based on the results obtained, the thermodynamic parameters for the O–H⋯N ⇆ O−⋯H–N+ proton transfer (PT) reaction were evaluated. The solvent effect on ΔGPT○, ΔHPT○ and ΔSPT○ is discussed in terms of two contributions. The short range solvation results from a specific direct interaction between the adduct and solvent molecules. The second solvation contribution can be ascribed to a non-specific long range bulk dielectric permittivity effect (reaction field effect). By using heterogeneous models of dielectric
medium as well as empirical solvent parameters an attempt was undertaken to analyse quantitatively the solvent effect on thermodynamics of proton transfer.


The present study has for objective to analyze the rationalization process in housing units through a new method of work programming and application of management techniques on site. If is necessary due to the currently level of competition, that drives builders and engineers to invest on planning and programming of works, through the production management, to quality guarantee and costs reduction in their constructions. To improve the productivity and to solve problems of scale, the companies have been opting for the services. Partnesing this situation brings advantages and disadvantages for the production. This work approaches production management, through planning techniques, mainly by PERT/CPM to become visible the rationalization process on site. On the site, the objective is to accomplish tasks that were planned with transparency, to collect, to process, and to analyze information, to compare the activities accomplished with the planned ones, using performance measurement to identify draw-backs in the construction and to coordinate the work process. Words key: construction, management and process transparency.


PURPOSE: A method of measuring a residual image of an LCD device is provided to configure a gray scale through a luminous value of a full white, which is measured by displaying the full white on an LCD, and a luminous value of a full black, which is measured by displaying the full black, and to measure a luminous changing rate in accordance with time of the full white displayed on the LCD by using the gray scale, so as to quantify a degree of a residual image. CONSTITUTION: A liquid crystal panel and a backlight are prepared, and a back light is irradiated on a liquid crystal panel from the backlight(100). The first full white state is displayed on an LCD screen of the liquid crystal panel, and a luminous average value of a full white is found by measuring luminous values at many spots of the LCD screen for the first full white(110, 120, 130). A full black state is displayed on the LCD screen(140, 150). A luminous average value of the full black is found by measuring luminous values at many spots of the LCD screen for the full black state(160, 170). A gray scale is configured through the luminous average values of the full white and the full black(180, 190, 200). The same voltage as the first full white is applied to the liquid crystal panel to display the second full white on the LCD screen(210). A luminous change is measured by using the gray scale at many specified spots of the LCD screen according to time for the second full white state(220).


Summary Delignification of spruce (Picea abies [L.] Karst.) during ASA (modified alkaline sulfite/anthraquinone pulping with alkali splitting) and magnesium bisulfite pulping was studied on a cellular level using scanning UV microspectrophotometry. This improved cellular analytical technique enables direct imaging of the topochemistry of lignin removal within the cell wall at different stages of cooking. The cooks were performed in a laboratory digester with forced liquor circulation. At 30 min intervals samples were taken for chemical and UV microscopic analyses. UV microscopy reveals that delignification during ASA pulping starts in the region of the pit canals and proceeds evenly across the entire S2 layer. As a specific feature of bisulfite pulping, a partial delignification of the radial compound middle lamella can be detected after 60 min of cooking. After 120 min, in both processes, the delignified cell walls show low UV absorbance values of both S2 and compound middle lamella. At this stage, approximately 90% of the initial lignin content is removed. At the end of both pulping processes, only parts of the cell corners can be distinguished by the new UV scanning technique.


This article emerges from a workshop titled "Producing Efficacious Medicine: Quality, Potency, Lineage, and Critically Endangered Knowledge," held in Kathmandu, Nepal, in December 2011. An experiment in collaborative event ethnography (CEE), this workshop brought together Tibetan medicine practitioners (amchi) from India, Nepal, and Tibetan regions of the People's Republic of China, with anthropologists who have been working with amchi for decades. This workshop focused on practitioners who still compound and prescribe their own medicines, in an era when such practitioners are declining in number due to rapid commoditization of Tibetan medicines, shifts toward standardized mass production, institution-based education, and the implementation of pharmaceutical governance regimes derived from biomedicine. The workshop aimed to encourage knowledge exchange between diverse practitioners and generate new, collective, and more nuanced anthropological knowledge about Sowa Rigpa epistemology, history, theory, and practice. Our method of choice was collaborative event ethnography formulated as a workshop in the most literal sense of the word: a space where artisanal forms of praxis were honored and where material things—medicines—were collectively made. This article discusses how this CEE experience departs at the level of scope, structure, and implications from other collaborative, event-based ethnographic practice described in the anthropological literature.

To study the effect of Yiqi Fanggan Mixture on the anti-stress response and immunity of mice, a Chinese herbal compound (composed of some tonic Chinese medicine, including astragalus flavone, deep-fried atractylodes macrocephala koidz, fortune eupatorium herb, cyrtomium fortunei, white cardamom, windproof, dyers woad root, licorice, jobstears seed) was given to the mice for intragastric administration once a day for 2 weeks. Mice in each group are subjected to normal pressure hypoxia test, swimming test, cold resistance test and high temperature resistance test. Organ index and serum hemolysin content of mice were also monitored. The results indicated that the Yiqi Fanggan Mixture can improve the survival time of mice under the condition of normal pressure hypoxia; prolong the swimming time and high temperature resistance time of mice; reduce the death rate of mice under the low temperature condition; and improve the activity of serum hemolysin and organ index of mice. The results showed that Yiqi Fanggan Mixture could improve the ability of anti-stress response and immune ability in mice.

This chapter describes a university/high school partnership focused on digital storytelling. It also explains the multi-stage process used to establish this successful partnership and project. The authors discuss the central role that technology played in developing this university/high school partnership, a collaboration that extended the impact of a digital storytelling project to reach high school students, university students, educators, high school administrators, and the local community. Valuing a reflective process that can lead to the creation of a powerful final product, the authors describe the impact of digital storytelling on multiple stakeholders, including the 13 university students and 33 culturally and linguistically diverse high school youth who participated during the fall of 2009. In addition, the chapter includes reflections from university and high school student participants expressed during focus groups conducted throughout the project. While most participants had a positive experience with the project, complications with the technology component often caused frustrations and additional challenges. Goals for sharing this project are to critically evaluate digital storytelling, describe lessons learned, and recommend good practices for others working within a similar context or with parallel goals.


ABSTRACT: Such wording in an-Nisa (34) states that the position a husband in a family is higher than a wife due to the fact that a husband has an obligation and a bigger responsibility for a wife and children. Both f them are equal in rights and duties but the duties and responsibility to protect, keep from being sinful hat is forbidden by the religion and order the wife to act as demanded by the religion are under the responsibility and duty of a husband. A part from thot, the obligation to provide financial support is also part of the husband task. A wife who obeys to husband is going to be blessed as what she has done to her husban. The Position of Husband and Wife Based on Islamic Law


This study examined how phases of romantic relationship development (honeymoon, defining, and established) were related to positive and negative relationship qualities. Participants (N = 136) completed self-report measures. Results found significant differences between phases of romantic relationship development for all three positive relationship qualities, but each had a unique pattern of variation: (a) levels of intimacy had a linear increase across phases, (b) constructive communication strategies were higher in the established phase as compared with the earlier phases, and (c) negotiation was higher in both the defining and established phases as compared to the honeymoon phase. Results for negative relationships qualities found an inverted U-shaped pattern for both destructive communication strategies and psychological aggression.

Geophysical investigations were carried out using Resistivity, VLF and Magnetic methods to delineate the subsurface structure around the hot springs of Tarabalo in central Odisha. The present investigation aimed to delineate the shallow subsurface configuration of the study area to understand the probable fracture network and weak zones feeding the cluster of hot springs spread over the area. The study deciphers highly fractured three layered subsurface configurations with depth ranges of 1-50 m, 50-70 m and beyond 70 m consisting of different composition and physical properties. Resistivity study reveals a conducting channel continuing beyond 70 m depth which is also in accordance with the VLF results. The magnetic highs in the region surrounding the hot spring may be due to the high iron content of Khondalite and Charnockite group of rocks which are overlaid by thick quaternary sediments. Thus, it can be inferred from this preliminary geophysical investigation that the hot springs in the study area are feeded by the heat source at a depth greater than ~70 m through some conducting channels and fracture network. A high resolution Gravity, magnetic and deep resistivity study is indispensable for a detailed understanding of the subsurface geothermal system.

- Successful crop establishment and high seedling vigor are considered as an important factor for the success of most field crops, as these parameters contribute to uniform plant growth and maturity, better struggle with weeds, and high productivity. Abiotic stresses adversely affect plant growth and productivity. In recent years, seed priming has been developed as an essential method to produce tolerant crop plants against various stresses. Seed priming is a method which is potentially able to promote rapid and more uniform seed germination and seedling growth in adverse environmental conditions and enhancing yield of a certain field crops. Seed priming is the cellular state in which the harmful effects of abiotic stress factors in plants are hindered by pre exposure to a stimulus, thus resulting in greater survival. It is becoming increasingly evident that different seed priming techniques in plants can improve the tolerance of crops to adverse environmental conditions. Generally seed priming shows potential strategy for increasing crop production and management in adverse environmental circumstances. Seed priming for enhanced resistance to of adverse environmental conditions obviously is operating various pathways involved in different metabolic processes. The seedlings emerging from primed seeds showed early and uniform germination. Moreover, the overall growth of seedling and plant is improved due to the seed-priming treatments, so that farmers or any of crop producers should be practice and apply the science of seed priming for maximizing crop yield in any of adverse environmental conditions


The present invention relates to a motor controller and related method. The invention is particularly well suited for use with an alternating current (AC) induction motor. Previously motor controllers did not take into account the combined effect a control circuit and controlled motor, had upon a mains supply and more particularly their separate and combined effect upon the power factor of an alternating current. The invention solves this problem by providing a motor controller which modifies an input current to an alternating current (AC) motor. The motor controller comprises: a power input rectifier; a low voltage power supply; a variable output voltage circuit for adjusting a drive output voltage circuit; and a control circuit arranged to control the variable output voltage circuit and to provide timed waveforms to the drive output voltage circuit.


The no-cloning theorem says there is no quantum copy machine which can copy any one-qubit state. Inner product preserving was always used to prove the no-cloning of nonorthogonal states. In this paper we show that the no-cloning of nonorthogonal states does not require inner product preserving and discuss the minimal properties which a linear operator possesses to copy two different states at the same device. In this paper, we obtain the following necessary and sufficient condition. For any two different states ∣ψ⟩=a∣0⟩+b∣1⟩ and ∣φ⟩=c∣0⟩+d∣1⟩, assume that a linear operator L can copy them, that is, L(∣ψ,0⟩)=∣ψ,ψ⟩ and L(∣φ,0⟩)=∣φ,φ⟩. Then the two states are orthogonal if and only if L(∣0,0⟩) and L(∣1,0⟩) are unit length states. Thus we only need linearity and that L(∣0,0⟩) and L(∣1,0⟩) are unit length states to prove the no-cloning of nonorthogonal states. It implies that inner product preserving is not necessary for the no-cloning of nonorthogonal states.


A vanadyl pyrophosphate catalyst for the selective oxidation of n-butane to maleic anhydride (MA) was prepared based on an improved route of the preparation of the catalyst-precursor VOHPO 4 .0.5H 2 O in aqueous medium. The precursor is synthesized by conversion of V 2 O 5 with H 3 PO 4 using oxalic acid as reductant and by a controlled procedure of crystallization. After transformation of the precursor into (VO) 2 P 2 O 7 by partial oxidative calcination the catalyst obtained is equilibrated within a few hours using a special conditioning procedure. The catalyst prepared exhibits a high activity and selectivity comparable to that of a catalyst prepared from organic medium.

The presented blind source separation algorithms are very complicated for the hardware with the real-time operation. According to the principles and characteristics of the blind source separation, a real-time blind speech separation algorithm which can improve both the separation speed and the separation performance is proposed. The simulating results show that the proposed algorithm is effective.


With the rapid development of robot technology and its application, manipulators may face complex tasks and dynamic environments in the coming future, which leads to two challenges of control: multitasking and changing load. In this paper, a novel multicontroller strategy is presented to meet such challenges. The presented controller is composed of three parts: subcontrollers, inner-learning mechanism, and switching rules. Each subcontroller is designed with self-learning skills to fit the changing load under a special task. When a new task comes, switching rule reselects the most suitable subcontroller as the working controller to handle current task instead of the older one. Inner-learning mechanism makes the subcontrollers learn from the working controller when load changes so that the switching action causes smaller tracking error than the traditional switch controller. The results of the simulation experiments on two-degree manipulator show the proposed method effect.


Ireland experienced significant competitiveness gains in the 1990s on the basis of the standard manufacturing unit labour cost-based measure of the real effective exchange rate. A few sectors mostly dominated by multinational companies have accounted for the bulk of value added in production. Their productivity gains have greatly contributed to Ireland's exceptional growth performance in the 1990s, which has earned it the nickname of "Celtic Tiger." However, these sectors represent a disproportionately smaller share of manufacturing employment, and competitiveness in employment-intensive sectors has been much weaker. This paper thus explores Irish competitiveness from the viewpoint of risks to employment.
