Presence of micro cracks leads to deterioration of concrete and entrance of unwanted substances into concrete. Micro cracks also lead to the corrosion of structures eventually and the structure needs rehabilitation. Due to side effects of chemical techniques biological rehabilitation techniques have been adopted as environmental friendly methods. Certain microorganisms have been identified with the ability to deposit calcium carbonate. Bacillus subtilis bacteria present in soil is adopted for the present study due to its availability and resistance against varying pH conditions. Fly Ash is an industrial by product which is harmful for environment and need to be recycled. Studies have proved the characteristics of Fly Ash in improving the characteristics of concrete. This aim of the present study is to find the effect of bacterial concrete with Fly Ash on strength characteristics of concrete. The effect of bacteria and fly ash on the mechanical characteristics of concrete and its effect in reinforced concrete members are studied. Keywords— Rehabilitation, Microorganisms, Bacillus Subtilis, Fly Ash, Mechanical Properties


The article analyzes regional energy cooperation in sub-regions of Asia with a detailed study of South Asia and the CIS. The aim is to develop the theory of energy markets integration by adding an element of mutual trade to it. The study is based on statistics data of electricity exports by sub-regions of Eurasia based on the information of bilateral exports. The level of regional economic integration was estimated by the "export share" indicator, as well as by graph theory methods. Four out of nine countries in the South Asian region are not yet included in energy trade. This fact does not allow to speak about the success of the efforts undertaken by international organizations in the subregion as a whole. The results of the network analysis show that the relations between the countries of the region are fragmented, the problem of South Asian countries integration in the field of electricity trade is far from a solution. In the CIS, only 10% of electricity is traded within the region. There are two clusters of countries in the subregion. The countries of the larger cluster are connected through trade with the rest of the world. The countries of the second cluster — Kazakhstan, Tajikistan, Kyrgyzstan and Uzbekistan — are interconnected, but not with Russia, being the beneficiaries of the Central Asian Regional Economic Cooperation Program. Thus, the prevailing architecture of regional ties may indicate small integration created by the efforts of an international organization in the region. The CIS region meets the description of the energy markets' integration level as being between "interconnection" and "shallow". To characterize the integration level, we recommend examining the graph connectivity, centrality indicators, and the number and size of clusters. Russia's efforts in the area of electricity trade in Asia are examined in four aspects. Development assistance is inadequate, and membership in the Asian Development Bank is likely to become a pressing issue. Cooperation with the CIS countries leaves aside two countries of the post-Soviet space, it is not able to attract four more countries of Central Asia to cooperate. Cooperation within the EAEU is insufficient for Belarus and Armenia, therefore, the creation of a single electric energy market by 2025 is an urgent task.


AbstractThe presented studies have been conducted on the scope and magnitude of damages inflicted by earthquakes over the years. Many RC buildings, designed and constructed in the 1960s and 1970s, have serious structural deficiencies, especially in their beam-column joints. Such deficiencies result from inadequate joint shear strength or confinement of column reinforcement. The joints require elaborate retrofit measures to ensure the performances comparable to those of new designed structures. In this research, a new seismic retrofitting method is presented for beam-column joints based on the two-dimensional enlargement of the joint by using steel plate, angles, and posttensioning rods. The seismic adequacy of deficient RC beam-column joints, and the efficacy of steel plates and posttensioning rods, have been investigated for retrofitted joints through experimental and numerical analyses. According to the results obtained through investigations, this new rehabilitation scheme is effective, simple to insta...

Red king crab (Paralithodes camtschaticus) formerly represented one of the most lucrative fisheries in the Bering Sea and Gulf of Alaska. Following rapid capitalization, the fishery exploded in the late 1970s with peak catches nearing 70,000 tons in the eastern Bering Sea alone, but in the early 1980s the productivity of this fishery collapsed by over an order of magnitude. Despite extensive management effort, harvest levels have remained fairly low and stable for the last 15 years. Factors in the life history of Alaskan red king crab and the Bering Sea ecosystem are discussed, especially as they pertain to continued low crab biomass. Reduction in crab abundance due to natural predators, habitat and resource limitations, and human impacts may present "bottlenecks" to future recruitment at a number of different life history stages. These stages include egg and larval supply, the early benthic phase, pre-fishery juveniles, and breeding adults. There is evidence that an environmental "regime shift" may have ...


Let K be a field (such as R, C,. . .), and let V = K 2 = {(s t) : s, t ∈ K} = {se 1 + te 2 : s, t ∈ K} (where e 1 = (1 0) , e 2 = (0 1)). Definition 1.1. A linear transformation is a map T : V → V such that T (αx + βy) = αT (x) + βT (y) for all x, y ∈ V and all α, β ∈ K. Claim 1.2. T is determined by the four scalars a b c d where T (e 1) = ae 1 + ce 2 , T (e 2) = be 1 + de 2 Proof. For the vector (s t) = se 1 + te 2 ∈ V , we have T (s t) =T (se 1 + te 2) = sT (e 1) + tT (e 2) = s(ae 1 + ce 2) + t(be 1 + de 2) =(as + bt)e 1 + (cs + dt)e 2 = as+bt cs+dt =: a b c d (s t) Matrix mutliplication is given by the composition rule: If T : V → V and T : V → V are linear transformations corresponding to a b c d and a b c d , then T • T is the linear transformation corresponding to aa +bc ab +bd ca +dc cb +dd =: a b c d a b c d In particular, matrix multiplication is associative and non-commutative. (Why? Because we know this for linear transformations). Also, if 0 = (0 0 0 0) is the zero matrix and I = (1 0 0 1) is the identity matrix, then (0 0 0 0) a b c d = (0 0 0 0) = a b c d (0 0 0 0) and (1 0 0 1) a b c d = a b c d = a b c d (1 0 0 1) Definition 1.3.

Firstly, if ad − bc = 0 then one easily checks that a …


The influence of wheat straw cover, tillage, and irrigation on metribuzin and alachlor movement and dissipation in an Appling coarse sandy loam (Typic Hapludult) and the influence of soil depth on their rate of dissipation were measured in field and laboratory experiments conducted in 1987 and 1988. Overall, metribuzin moved more than alachlor in both years. Alachlor movement was greater in tilled plots compared to no-till plots in 1988. Metribuzin movement was greater in no-till plots in 1987. Straw cover had little effect on the movement of alachlor, but the presence of 2800 kg ha−1 of straw on the soil surface increased the downward movement of metribuzin in both years compared to soil with no straw cover. The rate of alachlor dissipation in the soil was faster in straw-covered and no-till plots in both years and in the high irrigation level in 1988. Metribuzin dissipation was not affected by any of these factors. Alachlor rate of dissipation did not differ among depths in the field; however, dissipation differed in the laboratory in the order 0 to 20 cm > 20 to 45 cm = 45 to 68 cm. Metribuzin dissipated faster at the 8-cm depth in the field compared to the 58-cm depth. In the laboratory, metribuzin dissipation rates followed the order 0 to 20 cm > 20 to 45 cm > 45 to 68 cm. At the greatest depth, the dissipation of metribuzin was faster in the field than in the laboratory.

The study of retailing in the United Kingdom has tended to be empirical rather than conceptual in nature. By bringing together three well known but poorly integrated models of retail institutional change, this exploratory article endeavours to provide a theoretical basis for future discussion. The multi-polarisation model maintains that developments along one or more dimensions of retail activity eventually give rise to counterbalancing actions elsewhere in the commercial system.


The retinoic acid receptor α (RARα) plays a central role in the biology of the myeloid cellular compartment. Chromosomal translocations involving the RARα locus probably represent the malignant initiating events in acute promyelocytic leukemia (APL). Recent studies that identify novel interactions between RARα and the nuclear receptor co-activators and co-repressors. new functions of the oncogenic RARα fusion proteins and their catabolism in retinoic acid-induced differentiation, and the availability of new transgenic mice models have provided important insights into our understanding of the mechanisms by which mutant forms of RARα can be implicated in the development of leukemia. Novel alterations of the RARα gene identified in hematopoietic malignant disorders other than APL, such as myelody-splastic syndromes, non-APL acute myeloid leukemias and B-chronic lymphocytic leukemias, suggest that disruption of the RARα gene might predispose to myeloid and lymphoid disorders.


The product of the first n terms of an arithmetic progression may be developed in a polynomial of n terms. Each one of them presents a coefficient Cnk that is independent from the initial term and the common difference of the progression. The most interesting point is that one may construct an "Arithmetic Triangle", displaying these coefficients, in a similar way one does with Pascal's Triangle. Moreover, some remarkable properties, mainly concerning factorials, characterize the Triangle. Other related 'triangles' – eventually treated as matrices – also display curious facts, in their linear modus operandi, such as successive "descendances".

A variety of congenic resistant strains of mice sharing the B10 background have been examined for humoral responsiveness to the H-2D region private specificity H-2.32. All of these strains were found to produce little or no anti-H-2.32 antibody, confirming previous indications that the B10 background is defective with respect to this response (1). However, both strain B10 ( H-2 b ) and strain B10.D2 ( H-2 d ) did produce reasonable titers of antibodies reactive with public H-2D region specificities of H-2 k . In the case of B10.D2, this response could be shown to be due to a response to the D region product itself rather than a cross-reaction with public specificities shared in both K and D regions. By using sera to public and private H-2D k specificities sequentially to precipitate radiolabeled solubilized H-2 antigen preparations, both private and public specificities were shown to be present on the same molecules. Thus, the failure of B10 background mice to respond to the private specificity H-2.32 appears to be peculiar to this specificity and not to all specificities on the H-2D k molecule. Analysis of (AKR.M × B10.AKM)F 1 × B10.AKM backcross mice revealed that the magnitude of the antibody response to H-2 d antigens did not correlate with that of the anti-H-2.32 response, indicating the specific nature of the anti-H-2.32 low responsiveness of B10 congenic mice.


With efforts to reduce global reliance on fossil fuels and lower the greenhouse gas emission, an increasing search for renewably sourced materials, which can be used as feedstock for biofuel production, is ongoing in the past few decades. At the present, ethanol is the most
common alternate fuel and is already produced on a fair scale, representing a sustainable substitute for gasoline in passenger cars. Due to rapid growth in population and industrialization, worldwide ethanol demand is increasing continuously. Conventional crops such as corn and sugarcane are unable to meet the global demand of bioethanol production due to their primary value of food and feed. Therefore, lignocellulosic substances such as agricultural wastes are attractive feedstocks for bioethanol production. Agricultural wastes are cost effective, renewable and abundant.
Wheat has been used as supplementary staple food for thousands of years. Wheat bran is produced as a by-product in milling industries and one million tons of wheat can produce up to 0.25 million tons of wheat bran. The germ constitutes approximately 2.5 percent of the total weight of the wheat kernel. The germ probably contains about 20% of soluble carbohydrate, chiefly sucrose and raffinose. The other consideration is the presence of polyphenols in many varieties of wheat bran and wheat germ which are believed to reduce overall ethanol production.
The yeast cultures of Saccharomyces cerevisiae, Candida tropicalis from Food Microbiology Dept. CSIR-CFTRI. The Exiguobacterium isolated from soil sample was able to produce the enzyme which could hydrolyze some of the lignocellulosic waste and was hence used for the pretreatment of wheat bran and wheat germ. The comparative study of wheat bran and wheat germ fermentation showed decrease in the concentration of sugars, this indicates the utilization of pentose and hexose by the yeast. Fish meal extract from the, byproduct of fish waste processing was used as a replacement for yeast extract which worked better for alcohol production with Saccharomyces cerevisiae by using wheat germ as substrate which produced 2.7% alcohol. Qualities analysis of the alcohol showed 64.99% Ethanol, 14.86%Methanol, and 15.34% Isoamyl alcohol. Polyphenol degradation was observed in the fermented samples of wheat bran and wheat germ carried out by Saccharomyces cerevisiae and Candida tropicalis. The major fraction of phenolic acids obtained was Tannic acid, Galic acid and Caffeic acids. Therefore maximum recovery of sugars from wheat bran and wheat germ with less inhibitor concentration and subsequently their conversion into ethanol with desired yields and productivities are important factors to make bioethanol program successful at industrial scale.


To achieve effective security in the increasingly dynamic computing environment of the mobile workforce our perspectives on security have to change, requiring the development of new approaches. We discuss a new security paradigm, shrink-wrapped security, in which security services are tightly coupled to a user's situation, and present a framework to help enable its realization.


Abstract Establishing a lunar presence and creating an industrial capability on the Moon may lead to important new discoveries for all of human kind. Historical studies of lunar exploration, in -situ resource utilization (ISRU) and industrialization all point to the vast resources on the Moon and its links to future human and robotic exploration. In the historical work , a broad range of technological innovations are described and analyzed. These studies depict program planning for future human missions throughout the solar system, lunar launched nuclear rockets, and future human settlements on the Moon, respectively. Updated analyses based on the visions presented are presented. While advanced propulsion systems were proposed in these historical studies, further investigation of nuclear options using high power nuclear thermal propulsion, nuclear surface power, as well as advanced chemical propulsion can significantly enhance these scenarios. Robotic and human outer planet exploration options are described in many detailed and extensive studies. Nuclear propulsion options for fast trips to the outer planets are discussed. To refuel such vehicles, atmospheric mining in the outer solar system has also been investigated as a means of fuel production for high energy propulsion and power. Fusion fuels such as helium 3 (3He) and hydrogen (H

This paper proposes to diagnose stator winding inter-turn short circuit in double fed wind induction generator by zero sequence voltage.On the basis of the analysis of the mechanism how zero sequence voltage component generates,the paper points proposes to take zero sequence voltage as fault feature.The simulation model of DFIG is established to realize the fault simulation by changing the short circuit turns and resistance of the model.It also simulates and studies the stator winding inter-turn short circuit under different states when the rotating speed is constant.The simulation result shows that zero sequence voltage,generated following stator winding inter-turn short circuit,increases as the fault becomes more serious;zero sequence voltage,influenced by asymmetric power source and load condition,decreases weakly with the increase of load;the compensation for the influence of the non-generator fault is needed when diagnosis is carried out by zero sequence voltage.

Behavior in an organism is a result of networks of neurons producing meaningful patterns of activity. Neurons in culture reorganize themselves into twodimensional networks whose activity can change over time spontaneously or as a result of chemical or ph ysical stimuli. The neurons in culture are a promising too l f r the study of the auto-organization properties of populations of neurons under controlled physiochemi cal conditions. Networks of neurons in culture can be considered to be new rudimentary biological systems [1]. Solid State microelectronic technology can be utili zed to design and fabricate a chip allowing the user to si mulate a living neural network. Neurons are cultured in cel l culture media solutions such as Dubelcco's Modified Eagle Medium (DMEM), Leibovitz's L-15 medium and Leech Ringer solution.


Abstract There is a growing recognition that creativity is a key factor to an organization's innovation capacity. When facing challenging problems, organizations tend to rely on facilitated idea generation sessions. During these sessions, people are progressively applying different creativity techniques to generate creative solutions. The aim of the current paper was to examin the effect of four idea generation techniques—Silence, Evolution, Random Connections, and Scamper— on the ability to generate creative solutions, and to shed light on the question whether the idea-generation techniques built on each other. The number of solutions generated did not differ between techniques, suggesting that ideation does not get exhausted. With regard to idea quality all four techniques brougth about equal levels of originality. A difference was found between the techniques on usefulness and flexibility, technique 'Random connections' outperformed technique 'Evolution'. Moreover, the current paper examined whether idea generation in groups after individual idea generation has any benefit over-and-above generating ideas individually. The number of ideas generated in groups did not increase nor decrease. Importantly, however, overall the originality did significantly increase, suggesting that generating ideas in a group after generating ideas individually has a beneficial effect on the quality of the ideas generated.


this argument has some merit. It may be difficult, in a particular case, to know whether a particular state consists of more than one political community, and to know whether, in the absence of elections or a referendum, particular leaders adequately represent the communities they claim to lead. In this respect, however, Cyprus is an easy case. There can be little doubt that Cyprus has long consisted of two distinct political communities, or that Makarios and Kutchuk each led one of those communities. The 1960 elections confirmed the political standing of Makarios and Kutchuk, and effectively ratified their 12 Necatigil, The Cyprus Question at 11 (cited in note 91).


Indonesia has enough access to freshwater resources of the planet. However, uneven distribution together with mediocre water management and a lack of water infrastructures make a significant number of households in this country have inadequate access to safe water. This becomes big issues, because the provision of safe water, sanitation and hygienic conditions are essential to protect human health and save humanity during the Covid-19 pandemic. When this article was written, COVID-19 patients who were confirmed to be infected were in all Indonesian provinces, with the largest numbers of patients located in Java. The purpose of this study is to determine the efforts of the Indonesian government to fulfill its responsibilities in fulfilling clean water during a pandemic. The study collects all regulations and policies concerning clean water and an analyses them using doctrinal method. The result of the study shows that although there are enough regulations governing the use of clean water, they have not resolved the problem of clean water fulfillment. In overcoming water needs during the pandemic, the Indonesian government did not make additional efforts other than those previously planned in the Strategic Plan of the Ministry of Public Works and Housing. The disruption of the economy has an impact on state finance, causing the government to refocus budgeting. As a result, many programs related to clean water are postponed. This minimum effort by government is neglecting its responsibility in fulfilling the right to water. The government must emulate how to fulfill the needs for water during the pandemic from other countries and using this situation to fix the problem of clean water in Indonesia


In today's networked world, resource providers and consumers are distributed globally and locally, especially under current cloud computing environment. However, with resource constraints, optimization is necessary to ensure the best possible usage of such scarce resources. Distributed linear programming DisLP problems allow collaborative agents to jointly maximize profits or minimize costs with a linear objective function while conforming to several shared as well as local linear constraints. Since each agent's share of the global constraints and the local constraints generally refer to its private limitations or capacities, serious privacy problems may arise if such information is revealed. While there have been some solutions raised that allow secure computation of such problems, they typically rely on inefficient protocols with enormous computation and communication cost.In this paper, we study the DisLP problems where constraints are arbitrarily partitioned and every agent privately holds a set of variables, and propose secure and extremely efficient approach based on mathematical transformation in two adversary models --semi-honest and malicious model. Specifically, we first present a secure column generation SCG protocol that securely solves the above DisLP problem amongst two or more agents without any private information disclosure, assuming semi-honest behavior all agents properly follow the protocol but may be curious to derive private information from other agents. Furthermore, we discuss potential selfish actions and colluding issues in malicious model distributed agents may corrupt the protocol to gain extra benefit and propose an incentive compatible protocol to resolve such malicious behavior. To address the effectiveness of our protocols, we present security analysis for both adversary models as well as the communication/computation cost analysis. Finally, our experimental results validate the efficiency of our approach and demonstrate its scalability.

Having been requested to address in my remarks, first, what interesting disaster research is being conducted worldwide and, second, what important disaster research has not yet been addressed, I will do so. However, it is my intention to do so by providing a larger context than just simply answering the two questions.

This context involves stressing that what is needed is not simply more research, but different research, and this different research is to be achieved by the exercise of imagination and not by following in a rote fashion or mechanical procedures whether they be called the "scientific method" or something else.


With global economic integral and China's entrance to WTO, Chinese enterprise will face new challenge. If enterprise can keep on competing advantage, the key is enterprise's competitiveness. If enterprise governors can make a sound evaluation on enterprise's competitiveness and understand clearly to each main factor of competitiveness, those count for much to maintenance, promoting and development of enterprise's competitiveness. Therefore, the enterprise's competitiveness evaluation index system was designed, and points out the meaning and evaluation method of each concrete index. In the process of evaluating enterprise's whole competitiveness, the weight was settled based on analytic hierarchy way. Fuzzy comprehensive evaluation is main model. According to the evaluation result, enterprise governor can make a sound judgment on own enterprise's competitiveness. Finally this paper enumerates an example and makes a detail analysis.


Wireless technology (LAN) is a wireless communication technology and current developments are wireless sensor wireless networks (WSN). WSN is a combination of wireless modules, micro module and the sensor module, the way it works is the sensor response value to the micro module and the response values are transmitted through the wireless module. Based on how the WSN can be used for various purposes with one of them for monitoring natural disasters, and in this WSN is designed for monitoring natural disasters landslides. In general WSN systems have problems such as limited distance limitations. In this system the authors apply the WSN topology tree and spanning tree protocol (STP). Tree topology is a collection of star topology are connected into the bus topology as the backbone lines, while STP is a network communications protocol that has automatic backup paths if the main line is not active. By applying this system the maximum distance the receiving and sending of data between nodes without the use of the system is 100 meters with 34% packet loss, whereas by applying the system to 100 meters obtained packet loss is 20% and the maximum distance on the overall system is 140 meters with packet loss 30%. With these results we can conclude that the maximum distance is more spacious with menginplementasikan topology tree and adopt the spanning tree protocol.

Australia maintains one of the highest incidences of keratinocyte cancers in the world, with a high associated treatment cost. The nose is one of the most common locations for these skin cancers, representing a reconstructive challenge due to its unique 3D nature. As such, multiple patients are referred to sub-specialist units in metropolitan centres for their care, although this often is at an increased personal cost for regional and rural patients. Herein the author describes a case report of the use of chondro-cutaneous composite grafting for a nasal ala defect reconstruction, and potential use in peripheral and regional centres.


Random anomalous behavior is a false or redundant behavior that randomly appears in the network structure, affecting the analysis result of the network. Current methods mainly capture the relationship between entities in a complex network, using structure features to distinguish this behavior, which is known as graph-based anomaly detection. As a representation learning method that abstracts network entities into feature vectors, the graph embedding method is widely used in abnormal node detection and has been proven to have a relatively accurate detection effect. But it is difficult to apply in anomaly detection of numerous edges. Therefore, we combine the GCN and GAT based on node characteristics, proposing an anomaly detection model for random anomalous edges. It compares with other methods in 6 real networks and proves its effectiveness.


It is generally assumed the work-heat conversion rate in the plastic distortion of the metal under high strain rate is a constant in a range from 0.8 to 1.0,and in penetration engineering field,it is assumed as 0.9.In fact,the conversion rate should be a function of the strain,strain rate and temperature.A simple function is proposed.And the influences of the rates of 0.8, 0.9 and 1.0 and the function proposed on the prediction of temperature in the adiabatic shear band and the ballistic limit for some ballistic tests are compared by using AUTODYN-2D hydro code,based on the reported experiment conditions for 12 mm thick Weldox 700E steel plate targets perforated by 20 mm diameter blunt projectiles.The results show that the assumptions for the conversion rate of 0.8,0.9 and 1.0 estimate the temperature rise excessively,while the temperature rise estimated by the conversion rate function coincides with the experiment result better,and little difference in the ballistic limit predictions can be found in various conversion rates.


Seerfish ( Scomberomorus commersonii ) steaks stored in a combination of dry ice and ice at a ratio of 1:0.2:0.5 (fish:dry ice:ice) and in dry ice at a ratio of 1:1 (fish:dry ice) were found to be in good quality and sensorialy suitable for consumption when they were stored for 24 h and 30 h, respectively, without reicing. When fish steaks were stored in ice at a ratio of 1:1 (fish:ice) as control, they were in good condition only up to 18 h. Total bacterial load ranged from 10 5 to 10 8 cfu . g, while total psychrophiles was from 10 2 to 10 5 cfu . g. Total lactics and H 2 S producers were found to be 10 1 to 10 4 cfu . g. Total histamine formers were from 10 2 to 10 4 cfu . g. Total coliforms were 1600 MPN . g at the end of the storage period. The TMA-N contents were within the limit of acceptability. Histamine contents varied from 0 to 20 ppm. A lowest temperature (–11.9°C) was observed in steaks stored in dry ice. Highest level of CO 2 was recorded in steaks stored in both the dry ice and combination of dry ice and ice. Staphylococcus constituted 37% of the flora in fresh fish followed by Proteus, Pseudomonas, Aeromonas, Bacillus, Alcaligenes, Micrococcus, Acinetobacter


: Mupirocin and the thiomarinols are assembled on similar polyketide/fatty acid backbones and exhibit potent antibiotic activity against MRSA. They both contain a tetra-substituted tetrahydropyran (THP) ring essential for biological activity. Mupirocin is a mixture of pseudomonic acids (PAs). Isolation of the novel mupirocin P containing a 7-hydroxy-6-ketoTHP from a  mupP strain and chemical complementation experiments confirm that the first step in the conversion of PA-B to the major product PA-A is oxidation at C-6. In addition, nine novel thiomarinol (TM) derivatives with different oxidation patterns decorating the central THP core have been isolated from gene deletion ( tmlF ). These metabolites are in accord with the THP ring formation and elaboration in thiomarinol following a similar order to that found in mupirocin biosynthesis, despite lacking some of the equivalent genes. Novel mupirocin-thiomarinol hybrids have been synthesised using mutasynthesis.


We propose a nested weighted Tchebycheff Multi-objective Bayesian optimization (MOBO) framework where we build a regression model selection procedure from an ensemble of models, towards better estimation of the uncertain parameters (utopia) of the weighted-Tchebycheff expensive black-box multi-objective function. In existing work, a weighted Tchebycheff MOBO approach has been demonstrated which attempts to estimate the model parameters (utopia) in formulating acquisition function of the weighted Tchebycheff multi-objective black-box functions, through calibration using a priori selected regression model. However, the existing MOBO model lacks flexibility in selecting the appropriate regression models given the guided sampled data and therefore, can under-fit or over-fit as the iterations of the MOBO progress. As it is too complex to a priori guarantee a best model in general, this motivates us to consider a portfolio of different families (simple-to-complex) of predictive models that have been fitted with current training data, guided by the WTB MOBO; the best model is selected following a user-defined prediction root mean-square-error-based approach. The proposed approach is implemented in optimizing a multi-modal benchmark problem and a thin tube design under constant loading of temperature and pressure, with minimizing the risk of creep-fatigue failure and design cost. Finally, the nested weighted Tchebycheff MOBO model performance is compared with different MOBO frameworks with respect to accuracy in parameter estimation, Pareto-optimal solutions and function evaluation cost.


The paper wishes to analyse the effects of Directive 2014/104/UE on civil proceedings. It departs from the idea as to which legal protection offered by traditional judicial actions is a mere backing compared to the procedures of public enforcement before Independent Authorities.


The article reveals the prescriptions of the Civil Code of the RSFSR of 1922 on the grounds and consequences of invalidity of transactions; problems that arose in practice in their application are discusses.


Industrial restructuring and upgrading in academia and industry has formed a broad consensus,but the restructuring and upgrading are interrelated and mutually distinguishable concepts.On the basis of elaborating the need for industrial restructuring and upgrading,this paper redefines the concept of industrial restructuring and upgrading using the two concepts of "vertical industrial structure" and "horizontal industrial structure".It further analyzes the specific path of restructuring and upgrading from the four aspects of inter-industry restructuring,intra-industry restructuring,industry upgrading,and inter-industry restructuring and upgrading.


Sea Surface Temperature (SST) is an important factor in influencing marine life. Sea Surface Temperature measure using the remote sensing method. In situ data collection was carried out on December, 20th – 21st 2018 which covering 20 stations. The purpose of this study was to map and analyze sea surface temperature distribution in the East Coast Waters Central Bangka Regency using Landsat 8 Satellite Imagery in 2015-2019. Based on the Split Window Algorithm method R2 value obtained from the regression of image and in situ data is 0.8623. Map sea surface temperature was created using model y = -0.0588x3 + 5.0123x2 - 141.79x + 1358.6. Sea surface temperature in the East Coast Waters Central Bangka Regency in the past 5 years has changed fluktuatively with a range 28.4 – 30.1°C. Sea surface temperature values are getting closer to the land which is increasing due to the movement of fresswater mass from the rivers stream near the coast.

This article examines literature, and proposes a conceptual model to guide research in exploring these activities. The proposed model can also assist SMEs in developing and refining their offline and online marketing practices.


A previously unknown mimetic assemblage of the cerambycid Elytroleptus rufipennis (LeConte) and an undescribed lycid species was found on Quercus near Soyalo, central Chipas, Mexico. The behavioral differences between the lycid and its sibling are emphasized as possibly being significant in regard to pre- dator relationships. Throughout the tropical and subtropical regions of the world, lycid beetles represent one of the largest groups of models for mimetic in- sects. Representatives of many insect orders, including Lepidoptera, Hymenoptera, Diptera, and Hemiptera, as well as other families of Coleoptera, participate in lycoid mimetic assemblages which may have great complexity. In these assemblages the lycid model presumably is distatsteful to predators and the Batesian and Mullerian mimics thus gain protection by having a lycoid pattern and coloration. Several of these assemblages have been described from southeastern Ari- zona by Lindsley et al. (1961). As these authors point out, though, our knowledge of such assemblages has been largely derived from trop- ical regions of the Southern Hemisphere (see Lindsley e tal. for part of this literature). Thus further descriptions from the Northern Hemi- sphere are of particular interest. Reported in the present paper is a pre- viously unknown mimetic assemblage of a rare cerambycid and a lycid species from the mountains of the southernmost state in Mexico. The mimetic assemblage was found on a single small-leafed oak (Quercus sp.) tree in a partially-cleared, deciduous forest at an eleva- tion of 5300 feet above sea level in the central mountains of Chiapas (7.5 kilometers N.E. of Soyalo; N. of Highway 190 between Tuxtla Gutierrez and San Cristobal de Las Casas). When first observed (April 18, 1959) the two mimetic species were flying actively about the tree throughout the day; individuals landed on the oak leaves and branches at fairly frequent intervals. Specimens were taken after two days of observation (these were identified through the efforts of E. Gorton Lins- ley, University of California, Berkeley). The cerambycid, Elytroleptus rufipennis (LeConte), is a species known only from southeastern Ari- zona and the type material collected in Mexico before 1885. The lycid is apparently undescribed (R. D. Pope, British Museum, in litt.).


Septicaemia is a significant cause of morbidity and mortality in neonates. Meningitis is a serious problem in newborns with high mortality and frequent neurological sequelae. In neonates, signs and symptoms of infections are often obscure and clinical examination cannot distinguish septicaemic babies with or without meningitis. Therefore, lumbar puncture is often not done in time and thus diagnosis of meningitis is missed. Our aim was to see the association of bacterial meningitis in neonatal septicaemia and their clinical and bacteriological profile. This study was performed at the neonatal ward of Kumudini Women's Medical College Hospital from August 2007 to July 2009. All admitted newborns diagnosed as septicaemia clinically were enrolled prospectively. Detailed history was taken, thorough clinical examination performed, and blood culture, CSF study and other relevant investigations were done. Patients received standard medical care and followedup daily till discharge/death. Among 86 suspected cases, 30 (34.9%) had positive blood culture. Common clinical presentations of culture-positive cases were poor feeding (86.7%), lethargy (70%), respiratory distress (56.7%), fever (46.7%), jaundice (33.3%), seizure (26.7%) and cyanosis (20%). Male child outnumbered the baby girls (1.7:1). Other risk factors were maternal fever during delivery, prolonged rupture of membranes, birth asphyxia and poor socioeconomic status. Majority (63.3%) of the cultures isolated gram-negative bacilli, most commonly Klebsiella pneumonia (16.7%), Pseudomonas sp. (16.7%), and Acinetobacter (10%). Staphylococcus aureus (20%) was most common among gram-positive organisms, followed by Streptococcus pneumoniae (10%); no Group B streptococcus was isolated. Associated meningitis was present in two cases (6.7%) and nine out of 30 culturepositive cases (30%) died. This study confirms that neonatal septicaemia is a major problem in perinatology with high case fatality. As associated meningitis is difficult to distinguish clinically, CSF study needs to be included in septicaemia screening. An alarming finding of the study is that high proportion of the organisms are resistant to most of the commonly used antibiotics, again emphasize the importance of judicious antibiotic use.

Abstract A lumped parameter model was developed for hydrodynamically lubricated bearings: elements that feature fully lubricated contact between surfaces in relative motion. The bearing models were represented as bond graphs. Currently, bond graphers view bearings as single-port resistance elements, which only account for losses associated with relative tangential motions between surfaces. Machine designers view bearings as devices that generate forces normal to surfaces in relative motion, to maintain position and alignment of shafts or surfaces. Both effects occur in real bearings, coupled together via physics. A lumped parameter model for hydrodynamically lubricated bearings is developed in this paper. The model includes the physical coupling between rotational degrees of freedom and orthogonal degrees of freedom associated with maintaining alignments. These lumped parameter models were synthesized from solutions of the Reynolds equation for various bearing geometries, and include normal motion and squeeze film effects. Since the forces, velocities and displacements pertaining to these orthogonal motions are physically coupled via viscous and constriction effects in the bearing's lubricant flow, the bond graph models involve resistive fields. Examples apply these concepts to thrust and journal bearings.


Formanilide has been investigated by molecular beam Fourier transform microwave spectroscopy. The rotational spectra of two conformers, with the formyl hydrogen cis or trans with respect to the phenyl group have been measured. Their relative energy has been estimated to be 350 ± 150 cm−1, the trans form being more stable. In the cis species the plane of the pseudo-peptidic group forms an angle of ±34.7(5)° (equilibrium value) with the ring. The two equivalent configurations, corresponding to the + or – sign, are tunnelling through a barrier to planarity of 152(2) cm−1.


Plant growth promoting rhizobacteria (PGPR) are known to influence plant growth by various direct or indirect mechanisms. The plant growth promoting attributes viz. production of indole-3-acetic acid (IAA), gibberellins, siderophore, and phosphorus solubilization etc. ability of the rhizobacteria are the most common. The Phosphorus Solubilizing bacteria are used as plant growth promoting bacteria (PGPB). In search of phosphorus solubilizing Pseudomonas associated with wheat plants grown in various locations of Uttar Pradesh, we have isolated a total of sixteen strains on the kings B medium and identified as Pseudomonas spp. .Phosphorus solubilizing capabilities as demonstrated by the formation of clearing zone on the pikovaskya medium. Out of 16 Pseudomonas strains, only 9strains were found able to solubilize phosphorus. All the Pseudomonas strains were screened for salt tolerance. Most of the Pseudomonas strains shown tolerance up to 8% NaCl concentration. Only 3 Pseudomonas strains were able to grow even at 10% NaCl concentration.


In this study, we conducted experiments using fifteen types of actual vibrations in detached houses. The objectives were to examine the influence of changes in the characteristics of the predominant frequency and the waveform pattern and to investigate the characteristics of sensory evaluation. The effects of predominant frequency and waveform pattern were non-significant. When psychological quantity was small, the evaluation curve tendency for feelings of anxiety and discomfort with random vibrations was similar to that of the perception of random vibrations. Conversely, when psychological quantity was larger, the effect of predominant frequency became smaller for feelings of anxiety and discomfort.


Decades of educational banners have promoted "Early childhood," "Prevention," "Critical periods of development," and a host of other phrases that have focused the resources of dollars, programs, and time on the youngest of our charges in public schools. It it really too late by the time youngsters get to high school? Don't bet your neurons on it!


Chemical pesticides have been widely overused by farmers in Iran, but farmers' criteria for pesticide selection and use are not well understood. A field survey of 411 farmers was carried out in Mazandaran, Iran, to study farmers' criteria for selecting and using pesticides in the pest control process and explaining differences in selection criteria among farmers. From a list with a total of 25 criteria, five main groups were identified as key decision criteria for pesticide selection and use, using factor analysis. These groups included: (i) performance and effectiveness criteria, (ii) awareness and information criteria, (iii) technical and operational criteria, (iv) environmental criteria, and (v) financial and accessibility criteria. Performance and effectiveness criteria had the highest importance for farmers when selecting and using pesticides (mean 3.45), followed by financial and accessibility criteria (mean 3.28). Farmers who received training regarding pesticide use (mean 2.23 vs. 1.90) and farmers who had experience with integrated pest management (IPM) practices (mean 2.46 vs. 1.79) tended to consider environmental criteria when selecting and using pesticides. Similarly, farmers who experienced health risks related to working with pesticides (mean 2.0 vs. 1.77), farmers who used protection when spraying (mean 2.58 vs. 1.87), and farmers who knew about natural enemies of pests (mean 2.11 vs. 1.85) tended to consider environmental criteria when selecting and using pesticides. Farmers without off-farm income tended to consider financial and accessibility criteria more than farmers with off-farm income (mean 3.40 vs. 3.18). Farmers with college education favored awareness and information criteria, whereas experienced farmers favored the criteria of performance and effectiveness. Farmers with a high income showed a tendency to prefer performance and effectiveness criteria more than farmers with less income. Farmers who thought that pesticides are hazardous preferred environmental criteria more than farmers who thought that pesticides are not hazardous. Farmers who believed in the effectiveness of alternatives to chemical pest control (e.g., use of biological control, pheromone traps, or cultural control) preferred performance and effectiveness criteria less than farmers who believed no effectiveness or slight effectiveness of alternatives to chemical pest control. The findings provide useful information for better understanding factors affecting farmers' choices of pesticides and for improving future extension courses related to farmers' decisions about pesticide use.

As institutions have expanded their virtual learning options to reach a broader community of learners, they have also increased the number of virtual faculty—largely adjunct or otherwise contingent—working remotely from the primary institution's location. Supporting the professional growth of these geographically dispersed faculty members presents complex challenges for faculty developers, who, often with limited resources, must adopt new approaches. Against this backdrop are increasing expectations for all faculty to gain proficiency in new teaching methodologies, modalities, and learning analytics to increase student retention. This chapter reports on a comprehensive, multi-modal, and multi-perspective study undertaken by one institution regarding the needs of this changing faculty demographic, including virtual and face-to-face adjunct and full-time faculty. The research yielded insights from the student, faculty, and administrator perspectives. Recommendations are presented for creating accessible, relevant, and inclusive faculty development that integrates faculty at all ranks.


A multi-stage differential amplifier and method provides a gain versus frequency warping response characteristic that equalizes a transmission line of a given length to compensate for frequency-dependent attenuation. The warping response characteristic comprises the inverse of the attenuation versus frequency characteristic of the line, and affords a substantially flat system gain response over a predetermined frequency spectrum. The individual amplifier stages employ operational amplifiers, and are designed using SPICE simulations such that the individual responses of the stages are tailored so they combine to provide the required overall warping response to compensate the line.

Here, the opening cross sections of the second openings are smaller than the opening cross sections of the first openings.


The question of historicism, historical authenticity of folklore works has long been of interest to researchers, since oral history not only complements historical sources, but often presents a mixed interpretation of events and characters. In their own way, the people also interpreted the events of the Hungarian liberation revolution of 1848-1849 under the leadership of Layosh Koshut against the Hapsburg dynasty, combined with such a pressing issue for peasants as the abolition of the serfdom. The slavic folklore about Layosh Koshut is represented by folk songs and legends, and reproduces the main points of the liberation war: the mobilization of the local population, its struggle for freedom, the arrival of the Russian army and defeat, the capitulation and escape of Koshut, etc., as well as such a pressing issue for peasants as the elimination of the serfdom, which peasants associate with Koshut or with the Cossier. People's views on Koshut in songs are controversial. They partially contain anti-Hungarian motives, Koshut's condemnation, in others his defeat is sympathy. The peasants are struggling for national and social freedom, as opposed to the serfdom, which is devoted to many places in the folk narratives of the region. Over time, in folk works, there is a permutation of time and space, some historical characters and places are replaced by others, changing and actualizing. The article addresses the problem of historical authenticity of folklore works, peculiarities of reproduction of events by artistic and poetic means, their parallels with Hungarian sources, transformation and actualization over time.


Efficient cryptographic architectures are used extensively in sensitive smart infrastructures. Nevertheless, usual defects call for defence through design for fault detection and reliability. In this paper, we present implications of fault detection cryptographic architectures for smart infrastructures. In addition, we present new architectures for its nine-to-seven uneven substitution box. Through error simulations, we assess resiliency against false-alarms which might not be tolerated in sensitive intelligent infrastructures as one of our contributions. We further benchmark the feasibility of the proposed approaches through Field Programmable Gate Array realizations. Based on the reliability objectives, the proposed architectures are a stepforward toward reaching the desired objective metrics suitable for intelligent, emerging, and sensitive applications. The Proposed nine-to-seven uneven substitution box is done by Verilog HDL and Simulated by Modelsim 6.4 c and Synthesized by Xilinx tool and proposed system implemented in FPGA Spartan 3 XC3S 200 TQ-144.


In the last years, several standards and frameworks have been developed to help organizations to increase the security of their Information Technology (IT) systems. In order to deal with the continuous evolution of the cyber-attacks complexity, such solutions have to cope with an overwhelming set of concepts, and are perceived as complex and hard to implement. The exploration of the cyber-security state of an organization can be made more effective and proficient if supported by the right level of automation. This paper presents the implementation of a visual analytics solution, called CybeR secUrity fraMework BrowSer (CRUMBS) [2], targeted at dealing with the Italian Adaptation of the Cyber Security Framework (IACSF), derived by the National Institute of Standards and Technology (NIST) proposal [1], adaptation that, in its full complexity, presents the security managers with hundreds of scattered concepts, like functions, categories, subcategories, priorities, maturity levels, current and target profiles, and controls, making its adoption a complex activity. The prototype is available at: http://awareserver.dis.uniroma1.it:11768/crumbs/.


Microsoft, like other major software suppliers, is increasingly using disruption as a key tactic to fight cyber crime, adapting this approach as cyber criminals change their business models.

Botnets of hijacked computers form the backbone of cyber criminal operations, so it follows that taking down these networks is an important part of the work by Microsoft's digital crimes unit (DCU).

So far, the DCU in collaboration with cross-industry partners, has taken down six major botnets, (...)


Sir: In a recent communication0 we reported the isolation and structure elucidation of leucinostatin D, a minor, biologically active, peptide component of the antibiotic mixture produced by submerged cultures of Paecilomyces marquandii (Massee) Hughes. In a search for further biologically active metabolites, the darkbrownish oily residue from the benzene extract of the culture broth was subjected to repeated flash chromatography on silica gel colums using CHClgas the eluent to which MeOHand NH3 were added in continuously increasing proportions up to final composition CHC13MeOHNH3, 80:18:2. At the end of this procedure,


Background: Juvenile recurrent parotitis (JRP) is the second most frequent cause of repeated inflammatory episodes of the parotid gland (after mumps) that occurs in childhood. It is associated with non-obstructive and non-suppurative idiopathic dilatation of glandular ducts and affects mainly males. Nowadays, treatment of JRP attacks is mainly symptomatic and conservative. The main objective of the current article is to present two cases of JRP and to overview the existing literature about diagnostic and therapeutic utility of sialendoscopy in children suffering of this disease. Case summary: The authors present two clinical cases of first-onset JRP in a four and six-year-old female. One of them showed bilateral involvement and imaging confirmed the presence of multiple parotid microcysts without signs of lithiasic formations. In both cases, all acute crises were successfully treated symptomatically. In addition to recurrent episodes of parotitis, there were no other positive criteria for Sjogren 's syndrome, systemic lupus erythematosus or rheumatoid arthritis in any of our cases and none of them were positive for autoantibodies. Discussion: JRP is a self-limited condition that should prompt investigation for underlying diseases, such as Sjogren 's syndrome and other autoimmune pediatric disorders (mainly if there is bilateral involvement). Here we present two cases of JRP that lasted until pre-adolescence .


In this paper, the position control problem of the underactuated space robot with the effect of unknown external disturbance is addressed, and a new sliding mode control scheme is proposed. The underactuated system was divided into active subsystem and passive subsystem, and the Lyapunov functions and adaptive laws were designed for both subsystems by the adaptive backstepping algorithm which backstepping to the entire subsystem until the control law was finished. Combining with the subsystems' sliding planes a global sliding plane was constructed, then using the Lyapunov function and the exponential approach law with saturation function the control law for the entire system was derived. The control system is designed and simulated by proposed algorithm for two degrees of freedom underactuated space robot, and the simulation results have shown that the proposed algorithm not only can effectively and quickly implement the position control of the active and passive joints, but also can reduce the chattering caused by characteristic of the sliding mode control, and has robustness to the disturbance.


In order to screen the shade tolerance soybean lines, several important agronomic characters were studied after shade treatment at various growth stages. A severe influence of light reduction on agronomic characters found during the late flowering to pod filling period, and the response to shading was significantly different among the lines tested. Examining of pods number per plant after shade treatment during pod filling stage would be most effective method in the screening for shade tolerance soybean lines.


During a last decade interest in the field of schlerochronology intensified with the goal of identifying environmental changes from patterns observed in hard structures of various organisms including marine bivalves. Long lived species, such as members of genus Glycymeris, are potential model organisms for reconstruction of climate changes. In this study we investigated longevity and potential of Glycymeris bimaculata for schlerochronological analysis. Specimens were collected by SCUBA in February 2012 from Pag Bay and transported to the lab. Umbo region of each specimen was embedded in epoxy resin, cut along axis of maximal growth ; ground, polished and acetate peel replicas of shell sections were prepared. Age of the specimens included in the analysis exceeded 20 years, whereas maximal age determined was 24 years. Prepared slides were photographed, and distance between each growth line was measured. Each growth series were compared using SHELLCORR and chronologies were constructed with the dendrochronology software package ARSTAN using the cross-dated series of increment widths. Obtained data were related to environmental parameters including sea water temperature, air temperature and precipitation. Further more, results were compared to those obtained for G. bimaculata and Callista chione collected by hydraulic dredge in 2008.


Based on selective background updating,a new updating approach which determining updating speed by similarity was proposed.The energy function for dual-threshold segmentation was constructed based on color difference,connectivity and duty ratio,and the global optimal threshold was determined by simulated annealing algorithm.Coarse segmentation for the vehicle images was performed using optimal dual-threshold,a random label domain model was built by the time and space information in video spaces integrated with conditional random field tools,and refined segmentation,i.e.,fixing the labeling of pixel dots in coarse segmentation by computing the maximum posterior probability(MAP),was performed.Using the model of color space transformation,the problems of several disturbances in outdoor environment were dealt with,the color difference between foreground(vehicles) and background image was augmented,and the segmentation efficiency was improved.The simulation results show that good vehicle area can be obtained after the coarse and refined segmentation for the vehicle video image.Compared with other approaches,the proposed approach is more accuracy,robust and real time.


Reports the results of an attempt to relate the military treatise of the ancient Chinese strategist Sun Tzu to strategic quality management. Two sets of 20 statements were compiled, one from the work of Sun Tzu and the other from the concepts of strategic quality management. A group of employees experienced in quality management was then asked to indicate on a discrete scale the relevance of each statement in terms of its applicability on quality management. The rankings and correlations of the statements are presented and discussed. The results indicate a degree of relevance of Sun Tzu's insights to strategic quality management in an Asian context.


Presented herewith are the possibilities of image analysis of micro- and macroobjects in wood technology and forestry. Described hardware and software needed to established an operational image analysis system. There is also described how to convert analogue pictures into a digital form and how to enhance image quality of the image. Image analysis is a five step process: (1)capturing the image, (2) enhancing the quality, (3) thresholding, (4) calibration of the system and (5) measuring. Measuring could be done on the original image for density studies or on thresholded images for different kinds of object analysis. Finally, some theoretical and practical examples arepresented.


The system has a vehicle steering sensor 26 sensing the direction in which the vehicle is being steered, a source or radiation 10, and a movable reflector 14 which directs the radiation in a desired direction 15. A closed loop control system, responsive to the output of the steering sensor 26, moves the reflector 14 so that the beam is directed in generally the same direction as that in which the vehicle is turning. The reflector may either rotate or translate to change the beam direction. As described, a fixed reflector 12 directs microwave radiation from feed horn 10 onto elliptic paraboloid reflector 14 which either rotates about a generally vertical axis, or translates along a transverse axis of the vehicle.


The paper contains the development history, industrial testing, implementation demulsifiers domestic and foreign production used for the preparation of oil in the oil fields of Bashkiria, also concluded that the use of a certain kind of demulsifiers and their dosage per ton depends on the changes in the physical and chemical properties and composition of crude oil.


entertainment in theaters and homes, have found their way into classrooms. Teachers now often use mainstream entertainment films as a substitute for books and sometimes as a supplement to textbooks. Teachers also use films as a source of information and as material to be critically analyzed. Weinstein (2001) points out that classrooms today cannot be isolated from the cultural environment, and we cannot overlook the pervasiveness and influence of mass media. Using film to engage students in the study of history is a way of meeting students on their own turf. For example, Rebhorn (1987), an instructor of history, asserts that her students have a preconceived idea that history is boring and insipid because it deals only with events that have happened long ago and faraway, making the history discipline irrelevant. She claims that the use of Hollywood feature films has enriched the discipline of history and fostered her students' interest in historical events. In this article, I discuss the rationale for using films, specifically docudramas, for teaching social studies and present guidelines and resources for helping teachers to do so. I include several Web resources that assist teachers in the selection and use of specific films to complement classroom instruction. I have incorporated the comments of a classroom teacher in Logan, Utah, who uses films or segments of films in most of his history units. I selected Mark Dewey, a teacher at Mt. Logan Middle School, because parents, students, and colleagues consider him an excellent history teacher, especially because of his creative use of film to engage students in historical study.


In this paper, by taking both sensing performance and energy efficiency into consideration, the Cooperative Sensing Scheduling (CSS) problem for multi-band Cognitive Radio Networks (CRNs) is investigated under a practical scenario where both Primary User (PU) channels and Secondary Users (SUs) have heterogeneous characteristics. Unlike many existing works that merely claim that the CSS problem is NP-hard and then turn to heuristic methods, we analyze this problem under a solid discrete-convex framework. After formulating the CSS problem as a nonlinear binary programming problem, we adopt a three-step approach to solve it. In the first step, the number of SUs assigned to sense each PU channel is determined with the M/M^natural-convex theory. Based on the results obtained in the first step, we then find the SU assignment using the L/L^natural-convex theory in the second step. In the last step, the optimal number of SUs participating in sensing is obtained based on the SU assignment obtained in step two. By combining these three steps, a complete and efficient SU assignment scheme is obtained. Numerical results are provided to evaluate the performance of our proposed SU assignment scheme and validate the theoretical analysis.


Particle physics research demands unique data acquisition instrumentation in terms of speed, size, cost and architecture. This paper will focus on principal issues related to trends in high-speed, large-scale, economical, sophisticated instrumentation for high energy physics, heavy ion, nuclear and atomic physics as well as large scale astronomical experiments. Examples will be taken from experiments at many national laboratories including BNL, FNAL, CERN, SLAC, etc. as well as LeCroy Corporation's 26 year history in the field of physics research instrumentation.


The acid neutralization method and manometric procedures, using several acid-reducing agent combinations, were compared to determine their suitability for carbonate determination in organic soils. The soil–acid reaction observed with the acid neutralization procedure was significantly influenced by the acid concentration and soil type. Mean soil–acid reactions were 0.394 and 0.412 meq/g with the 0.3 and 0.6 M HCl, respectively. Moreover, it ranged from 0.023 to 0.694 meq/g soil for different soil types. The comparison of manometric procedures that were made used different acid-reducing agent combinations of HCl, CCl3COOH, HClO4, and SnCl2, and FeCl2. Of these, the HClO4–SnCl2 combination gave the lowest mean blank reading and standard deviation that remained stable (0.05 ± 0.009 ml). Though the perchloric acid alone is adequate for calcitic determinations, using the SnCl2 reducing agent with longer reaction times is recommended.


Graphite usually occurs in mineral/rock associations in the form of solid inclusions and plays an important role in tracing regional metamorphic degree, ore-forming temperature, fluid evolution, as well as the deep carbon cycle of the Earth. In this study, we investigate the placer black nephrite jade where the co-occurrence of abundant graphite inclusions and jade remains extraordinary. By employing petrographic, mineral-chemical, and Raman spectroscopic methods, we characterize the textures and crystallinity of graphite inclusions that exist in nephrite jade. EPMA and petrological data indicate that the main constituents of black jade are tremolite and graphite, with minor phases of diopside, calcite, dolomite, epidote, and apatite. Micro-Raman spectroscopic thermometry of carbonaceous material shows that most of the formation temperatures of graphite inclusions are between 378 and 556 °C, and only a few temperatures may be above 650 °C, indicating that graphite inclusions were formed at medium- to high-temperature metamorphic facies. The petrologic and spectral investigations of graphite inclusions in these nephrite jade samples show major metamorphic signatures with mixed features associated with fluid precipitation. Our results allow us to propose that primary nephrite jade was formed under multi-stage tectonic evolution conditions, and regional temperatures were predominately driven by the late continent–continent collision, while the ore-controlling temperatures of nephrite jade formation were found in a medium- to high-temperature environment.


'Zero hunger challenge' can no longer be a dream; rather we all can make it into reality. To reach it, we have to think with global hearts tuned with brain. In India, we are proud to have many such great global visioners starting from Swami Vivekananda to Prof. M. S. Swaminathan. Each human being of this globe has to think it seriously for the benefit of the 'living world'. Each one of us has to contribute towards such greater cause, i.e. , 'Zero hunger challenge'. It may be a drop but we all know when such drops coalesce then they change into a vast sea. Let us think into simple way a drop is 'symbolically a zero'. Our drive or vision is 'zero hunger challenge'. Hence we have to coalesce or converge our drop by drop efforts into totality of ' vast zero ' to bring sea change, i.e. , a big ' zero ' in hunger issue of the globe.


Abstract In order to develop the wastewater treatment technology for the refineries, the authors studied the biodegradation kinetics of the total petroleum hydrocarbon (TPH) in the refining wastewater based on the experiment data through simplifying the Monod equation properly. The biodegradation kinetics equation can be expressed as v = vmax = 0.25 . The microorganism UBD has strong ability for the biodegradation of the refining wastewater. It can be seen from the parameters of the kinetics equation that the TPH in the refining wastewater is not the nondegradation compound for the microorganism UBD.


Genetic hemochromatosis, with an allelic frequency of approximately 0.04 of HFE gene mutations, is the most prevalent inherited disorder in central Europe. Besides this most prevalent autosomal recessive mutation with exchange of the amino acids C 282Y, several other mutations in this and in other genes have been discovered. They all cause an impaired expression of hepcidin, an antimicrobial peptide predominantly expressed in the liver, which blocks iron uptake in the gut, and iron release from the reticulo-endothelial system. Disease manifestations of the locomotor system are frequent. Cystic arthropathy of metacarpophalangeal joints of the second and third digit are most frequent, followed by involvement of the wrist and hip joints. The typical changes of the joints include bone cysts, an initially enlarged joint space width followed by joint space narrowing in the later course, hook-like osteophytes, less frequent aseptic necrosis in the metaphyses, and generalised osteoporosis. Structural changes of the joints are irreversible under current treatment options. Correction of the iron status does not influence many of the joint-related complaints. However, an appropriate diagnosis is important since correction may avoid the endocrine, cardiac, and hepatic complications of iron overload. The diagnosis should be considered on basis of more than 55 % saturated iron binding capacity and increased ferritin plasma concentrations. Genotyping is still facultative for diagnosis, but may help in the screening of families for gene conductors. Phleobotomy is currently the most causative treatment option, until hepcidin substitution may become available. Symptomatic treatment of the arthropathic complaints includes analgesics and intermittent anti-inflammatory agents. Treatment of hemochromatosis osteopathy should be done in analogy to that of generalised osteoporosis.


In this paper, we describe the system we developed for the SemEval-2010 task of disambiguating sentiment ambiguous adjectives (hereinafter referred to SAA). Our system created a new word library named SAA-Oriented Library consisting of positive words, negative words, negative words related to SAA, positive words related to SAA, and inverse words, etc. Based on the syntactic parsing, we analyzed the relationship between SAA and the keywords and handled other special processes by extracting such words in the relevant sentences to disambiguate sentiment ambiguous adjectives. Our micro average accuracy is 0.942, which puts our system in the first place.


A limited slip differential includes a friction clutch mechanism, an electromagnetic coupling, and a camming mechanism disposed between the friction clutch mechanism and the electromagnetic coupling. The camming mechanism converts shearing forces within the electromagnetic coupling to an axial force applied to engage the clutch mechanism. The camming mechanism includes annular discs having axially inclined ramps, and a roller bearing for movement along the ramps to provide for variable spacing between the annular discs, wherein increased spacing is used to apply the axial force.


Quality evaluation and partitions of cultivated land are the premise and foundation for the basic farmland demarcated and high standard basic farmland construction. 10 indicators were selected to construct the evaluation index system from soil quality, infrastructure construction, spatial form and size. With the help of the GIS data processing and spatial analysis function, using the comprehensive index model, cultivated land can be divided into priority delimit, suitable, the key constructive and exit types of cultivated land in Beilin district of Suihua City. Due to comprehensive quality optima of the priority type farmland, it's the focus of the construction of high standard basic farmland object and food production and the construction of modern agriculture demonstration optimization area. Suitable to arable cultivated land also can be used as a priority area of the recent construction of basic farmland. Key constructive cultivated land should be taken to long-term land comprehensive improvement plan to build. Type out of cultivated land should not be defined as basic farmland. Research results provided the basis for basic farmland zoning and high standard basic farml and construction.


In standard agency models, only performance-based wages (monetary incentives) motivate an agent to work more. The present paper proposes a new agency model in which the principal makes an investment, in addition to the standard wage incentive, to raise non-monetary utility. We clarify two problems according to the type of non-monetary utility: the intrinsic motivation (IM) problem and the fringe benefits (FB) problem. The results of our analysis of both problems are as follows: (1) The results of the IM model and the FB model are similar regarding monetary payment. (2) Although IM is dependent on the attributes of a job and the worker, such as productivity or cost sensitivity, FB is not dependent on such factors.


For compounding languages, a great part of the topical semantics is transported via nominal compounds. Various applications of natural language processing can profit from explicit access to these compounds, provided by a lexicon. The best way to acquire such a resource is to harvest corpora that represent the domain in question. For Chinese, a significant difficulty lies in the fact that the text comes as a string of characters, only segmented by sentence boundaries. Extraction algorithms that solely rely on context variety do not perform precisely enough. We propose a pipeline of filters that starts from a candidate set established by accessor variety and then employs several methods to improve precision. For the experiments the Xinhua part of the Chinese Gigaword Corpus was used. We extracted a random sample of 200 story texts with 119,509 Hanzi characters. All compound words of this evaluation corpus were tagged, segmented into their morphemes, and augmented with the POS-information of their segments. A cascade of filters applied to a preliminary set of compound candidates led to a very high precision of over 90%, measured for the types. The result also holds for a small corpus where a solely contextual method introduces too much noise, even for the longer compounds. An introduction of MI into the basic candidacy algorithm led to a much higher recall with still reasonable precision for subsequent manual processing. Especially for the four-character compounds, that in our sample represent over 40% of the target data, the method has sufficient efficacy to support the rapid construction of compound dictionaries from domain corpora.

Brazilian petroleum is known by its high acidity due to the presence of acidic constituents, especially naphthenic acids (NA). The total characterization of the NA in petrochemical samples has been receiving special attention in research and comprises an analytical challenge, mainly due to the complexity of their mixtures. Gas chromatography with mass detector (GC/MS) is the technique of analysis more used, but recently comprehensive two-dimensional gas chromatography (GC × GC) has been used, due to its high resolution, peak capacity and sensitivity. The goal of this article is to discuss the techniques for sample preparation and analysis of NA in petroleum.


This article is the first study on Aristarkh Lentulov's workshops in the Free State Art Studios, VKhUTEMAS (Higher Artistic and Technical Workshops) and Moscow Art Institute covering the period of the 1920s–1930s. The study is based on the memoirs of Lentulov's contemporaries, archival documents (RGALI – Russian State Archive on Art and Literature; GA RF – The State Archive of Russian Federation). and students' works from Moscow and regional museum collections.
Post-revolutionary years were the time of the master's intensive pedagogical practice. In 1918–1919, Lentulov was in charge of the First Free State Art Studios (SGKhM) as their official representative. He led a painting workshop in the First SGKhM and a theater painting workshop in the Second SGKhM. In 1920–1925, he was a professor of painting and the head of the Theater and Decorative Art section at VKhUTEMAS. In the 1930's, he worked at Moscow Art Institute.
The painter's method which was shaping the tradition of "Moscow school of painting" is considered in relation to Lentulov's avant-garde experiments of the 1910's and in the context of the Knave of Diamonds group of the 1920s–1940s whose principles of painting he shared. The master's influence marked his student's works that showed interest in his "architectural" landscapes, cubist portraits, and so on. The Knave of Diamonds members paid particular attention to plein-air, the fundamental problems of painting with a special accent on coloring. Sharing his experience of a plein-air painter was another side of Lentulov's teaching practice. The methodology and some other issues of plein-air painting were the subject to a discussion between Lentulov and his colleagues at Moscow Art Institute in the 1930's. Aristarkh Lentulov's contribution to the development of "Moscow school of painting" deserves further scrutiny.


This paper discusses the uses of remote sensing and GIS data to monitor the health and resources of Bankhead National Forest (BNF), Alabama. The investigation focused on improving resource planning, eligibility determination of cultural and economic resources, and forest management, including understanding the disturbance regimes in the forest. The purpose of the study is to show that environmental disturbance in the BNF is infused in the land use planning systems; how the systems have affected the forest productivity in the past thirty years (1974-2004); how the changes relate to cultural and socioeconomic stability of the area; and to certify that the forest health has not been compromised due to systems change. The objective is the use of grounded theory research approach to promoted remote sensing and GIS data as instruments for data collection. Data analysis was done in: open, axial and selective coding procedures, to progressively collect and validate data correlations. It also used extensive ground truthing to obtain related measurements affecting the balance of the forest ecosystem. The goal or long-term objective is to be able to monitor the forest health by focusing attention on environmental interactions consisting of outbound---anthropogenic disturbance and inbound—natural disturbance now shaping the land use and the forest management. The goal also include developing a database from the coded data analysis, which constitutes benefits of ecological literacy, such as understanding socioeconomic activities, determination of eligibility of ground disturbance, and monitoring local economic resources and cultural development in the BNF.


Voice over Internet protocol (VoIP) over a wireless local area network (WLAN) is becoming an important application. However, the performance of voice over WLAN (VoWLAN) is compromised severely in the presence of heavy coexisting traffic from other applications even if the IEEE 802.1 le MAC protocol is utilized. This problem poses a severe challenge to the harmonious coexistence of VoIP and other application in WLAN. This paper proposes and investigates a scheme that modifies network allocation vector (NAV) update process of voice terminals. The extensive simulation in the paper demonstrates that the voice capacity of WLAN with coexisting applications of voice service and best effort service can be largely improved by the proposed simple solution compared with EDCA protocol. Specifically, in our proposed method, only the MAC protocol at the voice stations (STAs) should be modified, which makes the proposed solution more readily deployable over the existing network infrastructure.


The ever‐increasing water demands in the agricultural sector of the Mediterranean basin region (MBR) under climate change warrants that crop water productivity (WP) is a pertinent topic for discussion. Considering this need, this study aims to synthesize the body of knowledge on WP focusing on the MBR. The study is based on two test cases: (1) wheat, because it is a basic staple food in high dietary demand in the region and (2) barley, because it is a climate‐resilient alternative that is extensively cultivated in severe water‐ and salinity‐stress conditions. These staple crops are strategically important for regional food security in the MBR, which covers southern Europe, North Africa and western Asia. The study tries to investigate the plausible reasons for yield and WP gaps in the region. Our meta‐analysis revealed that wheat and barley are very different in their spatial distributions, productions and stress resiliencies in the MBR. Under the large gamut of biophysical and socio‐economic constraints that affect crop production, it is observed that the northern and southern parts of the MBR have large capacity differences (institutional, infrastructural and technical) in cereal production. It is noted that the role of soil‐water management in improving WP is vital and plays a critical role in closing yield gaps across the MBR. Moreover, the scaling of stress‐tolerant varieties along with a package of agronomic practices can enhance WP, and thereby we can make the region adaptive to climate change, especially in terms of water stress. The literature revealed that the MBR, especially the southern parts encompassing North Africa and western Asia, critically lacks comprehensive experimental/observational evidence on the dynamics of field water balance. This knowledge is key to enhancing WP assessments using modelling approaches. The paper concludes that the MBR does have water‐saving potential; it simply needs planned adaptation measures to enhance WP at the local and regional scales with effective benchmark studies in future.


Distributed optimization has become the norm for training machine learning models on large datasets. Learning bigger models on such systems leads to the exchange of large-volume updates. For this reason, limits on network communication in a distributed system can bottleneck learning progress. While compression techniques have been introduced to reduce bit-rates, no methods have yet leveraged the temporal structure that exist in consecutive vector updates. An important example is distributed momentum-SGD where temporal correlation is enhanced by the low-pass-filtering effect of applying momentum. In this paper we design methods that leverage temporal correlation to reduce bit-rates in systems employing momentum-SGD. We demonstrate that a significant reduction in the volume of communication can be realized. Experiments with the ImageNet dataset show that our proposed methods offers up to 40% bit savings compared to widely used methods such as Scaled-sign and Top-K.

In cooperative communications, multiple sources communicate with a single destination in the presence of relay nodes. Network coding in cooperative communications allows the relay nodes to combine the data received from the sources and send the linear combination to the destination. The difference in complexity, reliability and overhead is a critical issue when we compare among the different decoders. In this paper, soft-decision maximum a posterior (MAP) decoder that has an optimal reliability and neglected overhead is proposed. Moreover, the Sphere decoder is used to reduce the complexity of the proposed MAP decoder. The proposed implementation proves that the sphere decoder can be used to reduce the complexity of the MAP decoder to about 3% related to the original complexity of the decoder.


Like many scientists who were born right after World War II and who have learned a lot about physics, physical sciences, and biology from some of the incredible discoveries that were made in the defense laboratories, I have always been fascinated with Los Alamos. One of the marvelous opportunities that my job in Washington presented was to get to know a good deal more about the physical science world and the Department of Energy (DOE) laboratories, particularly Los Alamos since the Manhattan Project.
