Reversible data hiding(RDH) is a research hotspot in the field of information hiding. Among them, RDH based on histogram shift(HS) is a high performance algorithm. Accurate pixel prediction can reduce image distortion while maintaining high capacity. Therefore, this paper proposes an RDH algorithm based on the improved rhombus prediction method. Experiments show that the improved rhombus prediction method can predict pixels more accurately, and the generated prediction error histogram is more compact and clear. The proposed RDH algorithm has a higher embedding capacity and a lower distortion rate.


In Qing Dynasty the academic note-takings,with their imposing appearance and solid foundations,reflected the current trend of "advancing with the times",even founded the learned persons' correct approaches to scholarly pursuits showing their characteristics.Zhao's two notes not only outlined the scholars' specific method on cognition but also set up a special art of historical textual criticism.In order to clearly show the scholars' academic characters of Qing Dynasty,it is greatly significant to organize their theoretical frame.


In [1], J. M. Howie considered the semigroup of transformations of sets and proved (Theorem 1) that every transformation of a finite set which is not a permutation can be written as a product of idempotents. In view of the analogy between the theories of transformations of finite sets and linear transformations of finite dimensional vector spaces, Howie's theorem suggests a corresponding result for matrices. The purpose of this note is to prove such a result.


collaboration. Beattie's analysis of the work of the Bow Street Runners, as much as Eric Johnson's work on Nazi Germany, points to the extent to which success depended on good working relations with the populace a large, while Sinclair shows how policing in parts of Africa in the mid-twentieth century was severely hampered as the rise of nationalism disrupted mechanisms of consent and collaboration. It is difficult to do full justice to the richness of this collection of essays but brief mention must be made of Johnson's use of oral testimony in determining the positive image of (and hence the collaboration with) the Gestapo among 'ordinary' Germans, and of John Drabble's analysis of the role of the FBI and its contribution to the political consensus of 1960s America. Ultimately, this ambitious collection of essays raises more questions than it answers but this is its true strength.


Understanding the quantum nature of light in situations where it interacts very strongly with matter is a question that is becoming experimentally relevant for qubits coupled to new classes of metamaterials with impedance close to the quantum limit. This problem enters the realm of many-body physics because the effective fine structure constant reaches values of order one, so that perturbative methods and concepts of quantum optics cannot be simply borrowed. Remarkably, describing the time-dependent state vector in terms of quantum-superposed classical (coherent) states provides not only a very efficient computational tool, but also a simple way to rationalize the physics at play. By analyzing the Wigner distribution of the radiated field, we find that spontaneous atomic decay does not lead to the standard emission of one-photon Fock states, but rather to the release of many-body Schr\"odinger cats.


All the ten Trichogramrna parasite species were found to accept and successfully complete their development in the eggs of the teak skeletonizer, Pyrausta machaeralis Wlk. (Lepidoptera: pyralidae). Fresh and one days old eggs were found equally acceptable to all the ten Trichogramma species, but tWo days old eggs resulted in low pecentage of parasilization. The adults that emerged from P. machaeralis eggs were smaller in size when compared to the adults that emerged from the eggs of the laboratory host, Corcyra cephalonica Staint.


A combination of scintillometer measurements, ancillary meteorological data and an aggregation scheme has been used to derive area-averaged sensible and latent heat flux over a transect spanning three adjacent and contrasting vegetation patches: cotton, wheat and chickpeas. The results showed that modelled area-averaged fluxes compared fairly well with observations.


In reactor physics, two widely known numerical methods are used to solve neutron transport equations: deterministic method [1] and the Monte Carlo (MC) method [2]. The MC method is useful for solving complicated three-dimension (3D) problems. This method is especially suitable for complicated geometries which cannot be simulated explicitly by using deterministic code systems. However, it requires much larger computation time than the deterministic method to achieve a small statistical uncertainty. Fortunately, the immense development of computer science and technology permits applying the MC method in reactor core simulations and analyses. To improve the accuracy of reactor analysis tools for neutron-physics simulation, Ulsan National Institute of Science and Technology (UNIST) has been developing the MC code named MCS [3-6] to achieve a high accurate whole-core solution. Various types of verification and validation (V&V) work have been conducted on MCS to ensure its accuracy and reliability for nuclear power system design and safety evaluation. The primary goal of this work is to verify MCS using the VERA Core Physics Benchmark problems [5], which is directed towards the results of 3D multiassembly and whole-core simulations.


In recent years, we have seen huge growth of biometric systems incorporated in devices such as smartphones and security is one of the major concerns. In this work a multi-biometric template protected system is proposed, based on Bloom filers and binarized statistical image features (BSIF). Features are extracted from face and both periocular regions and templates protected using Bloom filters. Score level fusion is applied to increase recognition accuracy. The system is tested on a database, consisting of 94 subjects, of images collected with smart phones. A comparison between unprotected and protected templates in the system shows the feasibility of the template protection method with observed Genuine-Match-Rate (GMR) of 95.95% for unprotected templates and 91.61% at a False-Match-Rate (FMR) of 0.01%. Irreversibility and unlinkability of the system is analysed based on a recently published security evaluation framework.


Distant supervision (DS) has been widely used to automatically construct (noisy) labeled data for relation extraction (RE). To address the noisy label problem, most models have adopted the multi-instance learning paradigm by representing entity pairs as a bag of sentences. However, this strategy depends on multiple assumptions (e.g., all sentences in a bag share the same relation), which may be invalid in real-world applications. Besides, it cannot work well on long-tail entity pairs which have few supporting sentences in the dataset. In this work, we propose a new paradigm named retrieval-augmented distantly supervised relation extraction (ReadsRE), which can incorporate large-scale open-domain knowledge (e.g., Wikipedia) into the retrieval step. ReadsRE seamlessly integrates a neural retriever and a relation predictor in an end-to-end framework. We demonstrate the effectiveness of ReadsRE on the well-known NYT10 dataset. The experimental results verify that ReadsRE can effectively retrieve meaningful sentences (i.e., denoise), and relieve the problem of long-tail entity pairs in the original dataset through incorporating external open-domain corpus. Through comparisons, we show ReadsRE outperforms other baselines for this task.


The popularity of Android mobile devices has gone up in our lives and are being used for handling a lot of our personal and confidential information. Hence t hey are now an ideal target for attackers. Android based smart-phone users can download a lot of free applications from Android Application Market/Play Store. These downloaded apps some-times contain malware applications that can take possession of private information from users. Apps in queue for launching on Play Store generally undergo an automatic security test where crawl operations like typing, tapping and swiping are performed periodically and analysis results are generated. In this survey paper, we aim to briefly discuss the different techniques used in Android malware detection and highlight their advantages and limitations.


In many datacenters, server racks are highly underutilized. Rack slots are left empty to keep the sum of the server nameplate maximum power below the power provisioned to the rack. And the servers that are placed in the rack cannot make full use of available rack power. The root cause of this rack underutilization is that the server nameplate power is often much higher than can be reached in practice. To address rack underutilization, server vendors are shipping support for per-host power caps, which provide a server-enforced limit on the amount of power that the server can draw. Using this feature, datacenter operators can set power caps on the hosts in the rack to ensure that the sum of those caps does not exceed the rack's provisioned power. While this approach improves rack utilization, it burdens the operator with managing the rack power budget across the hosts and does not lend itself to flexible allocation of power to handle workload usage spikes or to respond to changes in the amount of powered-on server capacity in the rack. In this paper we present CloudPowerCap, a practical and scalable solution for power budget management in a virtualized environment. CloudPowerCap manages the power budget for a cluster of virtualized servers, dynamically adjusting the per-host power caps for hosts in the cluster. We show how CloudPowerCap can provide better use of power than per-host static settings, while respecting virtual machine resource entitlements and constraints.

A complete embodiment of the line in the world of architectural or near-architectural forms is undoubtedly the road, the binding thread. The essay considers roads as an ideal type, especially the roads outside settlements, which form, as the author seeks to show, a dialectical pair with cities. Other significant pairs are the landscape/road; place/"non-place"; interior/exterior, which are also the subject of the given reflections.


In the process of development and construction for urban waterfront,water system planning is one of the crucial foundations,as it can provide the favorable protection for accomplishing the construction in waterfront.In order to match the water system construction with urban functional position in urban waterfront,such factors as the connects among land use,vertical site,city landscape,flood control and drainage,and control of water pollution,as well as the general coordination for water system horizontal layout,and vertical layout,water system operation and sewage prevention and control should be taken into consideration.The article carries out the study based on an empirical case of urban waterfront water system in Jiangmen from four aspects including water system horizontal layout,vertical layout,water system operation and water pollution prevention and control.

With the continuous development of urban traffic, the coverage area of the subway has gradually expanded, and the number of subway tunnel construction has increased significantly. To ensure that the construction process does not affect the ground, the ground deformation prediction method of subway tunnel construction is often used to predict the ground conditions. The method is not strong enough to analyze the ground deformation mechanism, which causes the problem that the predicted result is quite different from the measured result. Therefore, a prediction method of ground deformation based on Gaussian process regression is proposed. Set the ground displacement monitoring process, combined with the characteristics of tunnel construction, complete the monitoring and analysis of ground displacement data. The mechanism of ground deformation is analyzed, and combined with the grey prediction model, the ground deformation is predicted. Based on Gaussian process regression equation and covariance calculation results, a ground deformation prediction model is established. So far, the design of ground deformation prediction method for subway tunnel construction based on Gaussian process regression is completed. Constructing the experimental link, the comparison shows that the prediction result of this method is closer to the actual measurement result, which shows that this method is more effective for ground deformation prediction.


Conservation is a complex process that is affected by culture, politics, economics and biology. Smith & Walpole (2005) are right to identify corruption as an important influence on conservation, and their goal, to stimulate debate and analysis of this problem, is meritorious. Here, I expand on three points to highlight some further complexities that arise from their work.


Side-chain prediction is an important subtask in the protein-folding problem. We show that finding a minimal energy side-chain configuration is equivalent to performing inference in an undirected graphical model. The graphical model is relatively sparse yet has many cycles. We used this equivalence to assess the performance of approximate inference algorithms in a real-world setting. Specifically we compared belief propagation (BP), generalized BP (GBP) and naive mean field (MF).

In cases where exact inference was possible, max-product BP always found the global minimum of the energy (except in few cases where it failed to converge), while other approximation algorithms of similar complexity did not. In the full protein data set, max-product BP always found a lower energy configuration than the other algorithms, including a widely used protein-folding software (SCWRL).


Legal Aid is organized to help resolve legal issues faced by Legal Aid Recipients. The birth of Law No. 16 of 2011 concerning Legal Aid provides new hope for the poor to gain access to justice and equality before the law. This writing aims to determine the implementation of the provision of legal aid and the obstacles that influence it in its implementation because sometimes the implementation of Law Number 16 of 2011 concerning Legal Aid in Indonesian Courts is not optimal. This research focuses on the application of legal aid to the poor, the challenges and problems they face. The method used in this research is empirical research. This study found that in the application of legal aid in several regions in Indonesia, the main problem faced in addition to the lack of availability of accredited legal aid institutions, was also the issue of the budget provided by the state. In addition, in terms of the legal culture of the community, the implementation of legal aid is not optimal due to the understanding of the community not to have anything to do with the law so that many cases that should receive legal assistance cannot be accompanied.


While the economy grows rapidly in China, many problems of industrial pollution have emerged. Nowadays, the environmental pollution has become a bottleneck of the economic development of our country. The paper firstly looks back to the former studies or literatures on pollution and environmental administration, and then uses Pigou Theorem, Coase Theorem and Tradable Pollution Permits Theorem to analyze the present situation of industrial pollution in our country and the environmental administration methods which our country used before. The paper concludes that the environmental administration methods of our country are falling behind the times. We have to combine the environmental administration methods with the economic ones and carry on a new environmental control system to ensure the sustainable development of our country.

In the subduction zone, oceanic plates start sinking into the mantle, and continental crusts are generated and eroded. So it is important for understanding the evolution of plate-tectonics. As for the subduction initiation, temporal change of thermal structure and water content of the mantle wedge is mainly estimated by numerical simulations (Iwamori, 2000 etc.), but there are few constraints from material informations. Using magma information is a possible method to estimate thermal structure of the Earth (Green, 1981). Although it is necessary to estimate chemical composition of the primitive magma, the effects of crystal differentiation and, especially in subduction zone, crustal process (magma mixing, crustal assimilation, and degassing) should be evaluated. Moreover, the magmatism in subduction zone is assumed to be affected by mantle flow in mantle wedge (Tatsumi et al., 1983; Tamura, 2003). To estimate such upwelling, Sakuyama et al. (2009) investigated temporal and spatial change of the magma generation field. SW Japan is an example of juvenile subduction zone. Shikoku basin initiated to sink 17 Ma ago, and magamatisms migrated from forearc to reararc (Kimura et al., 2005). In the Setouchi volcanic zone, the generation of high-Mg andesite (HMA) has been discussed from the view of thermal structure of the mantle wedge and subducting plate (Tatsumi & Hanyu, 2003 etc.), but there remains some questions about magma mixing and degassing, and about temporal and spatial change of magma generation field. In this study, we suggest a method to estimate the primitive magma composition by using oscillationally-zoned opx, and apply to the HMA in the Setouchi volcanic zone. And we try to estimate the magma generation mechanism by evaluating temporal and spatial change of magmatism in the area. Firstly, we investigated a HMA in Mt. Kiyama, central part of NE Shikoku, Japan (Sato, 1982 etc.). It has the most primitive composition (SiO2: 57.3wt%, MgO: 8.56wt%, Mg#: 69.3), and it contains olivine, opx, and cpx as phenocrysts. The olivine phenocrysts are normally-zoned, and their highest Mg# (87.6) is lower than the equilibrium value calculated from whole rock composition of the HMA (88.7). Therefor the olivine phenocrysts are considered to be crystallized in closed system. On the other hand, opx phenocrysts are reversely-zoned, and their composition boundaries are sharp. Moreover they have higher Mg# (up to 91.5) than calculated equilibrium value (88.8). Accordingly, these opx could record the composition of more primitive melts. And zoning pattern among opx is consistent, so they could reflect compositional change of the same melt. According to Putirka (2005), the composition of primitive magma can be estimated by adding fractionated olivine or opx until the melt's composition become in equilibrium with the opx which has the highest Mg#. But we must remove the effects of magma mixing before it. Kuritani (1998) used the fact that the An content of plagioclase phenocryst can be changed in a magma chamber reflecting the difference of temperature or water content. He investigated the pattern of zoning and quantity ratio of them, and estimated mixing ratio. We estimated the change of melt composition. (1) Calculating the melt compositions from opx composition by using distribution coefficients. (2) Comparing the change of the melt composition and modeled composition in Rayleigh fractionation or magma mixing. (3) Estimating mixing ratio by evaluating the pattern of zoning in opx and their quantity ratio, and estimating end member of mixing. (4)According to the true fractionation trend, determining primitive magma composition which is in equilibrium with opx having the highest Mg#. By applying this method to the HMA in Mt. Shichihousan, western part of NE Shikoku (Kawabata & Suto, 2000), we estimated the spatial change of primitive magma composition and magma generation field.

A convenient sonochemical process for the preparation of HgSe nanoparticles by using Hg(CH 3 COO) 2 and SeCl 4 in the presence of hydrazine as reductant agent has been discovered. Three capping agents have been used that including TEA (triethanolamine), SDS (sodium dodecyl sulfate) and TGA (thioglycolic acid). The products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), photoluminescence spectroscopy (PL) and X-ray energy dispersive spectroscopy (EDS). The effects of capping agent and reaction time on the morphology, particle size and phase of nano-sized HgSe products have been investigated.


In this research, an approach for predicting wind energy using machine learning has been explored. An indirect method has been adopted. Predicting wind speed at first using the hourly weather data and combining that predicted wind speed with the power curve of considered wind turbine prepared by the companies. This research aims to develop a generalized machine learning based wind power forecasting model for Bhutan. Thus, hourly weather data for the year 2018 and 2019 of 300kW On-grid Wind Farm at Rubesa was used to train the base model. Meanwhile, the trained base model was tested against the weather data sets for the selected sites namely Gaselo and Dagana. A Random Forest Regression machine learning algorithm was used in this research. The developed base model has five input variables which are time, temperature, global horizontal irradiance, relative humidity, and pressure, while the target is wind speed. The R- squared values, Root Mean Square Error (RMSE), and Mean Absolute Error (MAE) for the developed base model were found to be 0.88, 0.40 and 0.30 respectively. Energy output in the wind turbine was calculated via the predicted wind speed and power curve prepared by the wind turbine companies. The calculated energy output could shape the considered theoretical power curve. The power curve considered in the present research is 300kW On-grid Wind Farm at Rubesa, Wangdiphodrang.


This paper introduces new concepts for evaluation of the power system steady state operations, namely the vulnerability index (VI) and margin index (MI). They provide quantitative vulnerability and security margin information about generation, transmission, load conditions and then the whole system. System operators can assess the system security and vulnerability information using the margin and vulnerability indices. Therefore, they can take some preventive and emergency control steps to keep the system operating at the secure level

Based on the investigation data in the mangrove reserve at the Beilun River Estuary in Guangxi in May(spring)and August(summer) in 2013,the spatial and temporal distributions of the heavy metals(Cu 、 Zn、 Pb、 Cd、 Cr、 As、Hg) and influence factors were studied,and the pollution levels were evaluated.The results showed that the concentrations and fluctuation degrees of the heavy metals in surface seawater were different in spring and summer;the pollution of Hg was obviously more than the first category seawater quality standard,and the pollution in summer was more severe than that in spring.Cu and Zn,Cu and Cd,Zn and Pb,Zn and Cd were positively correlated with each other,and the concentrations of As in spring and summer and Cr in summer had a significantly positive correlation with salinity,respectively.The other heavy metals had no significant correlation with salinity.The temporal and spatial distributions of the heavy metals were mainly affected by the terrestrial input,diluted river water and salinity changes.


Spanish audiovisual law recognizes that children need a special care from broadcasters and to keep a strengthened schedule in. This article analyses if there is correlation between the real consumption that make viewers from 4 to 12 years and the time-slots that are proposed in the Bill. Through some audience data provided by Kantar media, it is investigated in an exhaustive and a compared way which are the hours with most children watching television, and which channels and contents are their favorites. It is concluded that the second hour with more kids in front of TV (from 22:00 to 23:00) is out of the strengthened schedule. The children´s favorite channels are Clan, Boing and Disney, with higher ratings than other. But children build their own audiovisual menu: they choose kids channels in strengthened schedule, but they look for other contents in prime time. Also is remarkable, that kids accompanied by adults consume more the general channels than the ones who do it without adults.


In many European countries, psychosocial risks such as work-related stress, violence, bullying and harassment have become major concerns for occupational safety and health. Has the development of instruments and approaches to meet these challenges kept pace? This article examines the role of European social dialogue as a relatively novel mode of regulation ('soft law') in the field of psychosocial risks, considering also the changing political and economic context of the enlarged EU. Although some progress has been achieved, diverging stakeholder perspectives and structural weaknesses still pose serious challenges to effective social dialogue in this area. We draw on the results of a recently completed project on psychosocial risk management, including the findings of a European stakeholder survey among experts in occupational safety and health.


This thesis consists of three essays on the understanding of political, social and industrial organization as roots of economic vices such as corruption and virtues such as social capital formation.The first essay is "The Organization of Corruption". We study how corruption between the State and the private sector is organized. Exploiting differences in the political and industrial organization across states in Mexico, we explore how party permanency and industry structure determine the extent of corruption. Using microlevel data, we find that the political clout affects corruption in a non-linear manner. Corruption is higher for high and low levels of party permanency, and lower for intermediate levels. We also find that firms endowed with larger rents are more likely to corrupt officials in exchange for economic shelter, except when permanency seems unlikely.The second essay is "Social Capital as Collateral in Microfinance". I explore the role of social capital as a form of collateral in microfinance programs, exploiting differences in levels of social capital across communities in Mexico. Social capital seems to serve as a form of collateral, as individuals in communities with higher levels of social capital are able to access larger loans, ceteris paribus. Clients with stronger direct ties to their peers also seem to have a higher borrowing capacity. Finally, social capital has a positive impact on clients' access to alternative sources of credit, and on their access to information on credit opportunities.The third essay is "Social Ties and the Limits of Mutual Help in Microfinance". I look at the role of social ties in determining dropout rates from microfinance programs. Mutual help imposed by joint liability is especially taxing on safer borrowers, increasing their likelihood of dropping out. I test the hypothesis that the sustainability of mutual help arrangements in the face of risk heterogeneity depends on the possibility of transfers between clients, which is facilitated by social ties. I find that strength-of-ties reduces the likelihood of dropping out, and increases the likelihood of peers helping each other. Relatively safer clients and clients with better outside options drop out more often, but the strength of social ties mitigates this effect, increasing the degree of heterogeneity that safer clients tolerate.


Rafael José Correia Batista v Abstract The research presented here, focus on the development of a compact twisted string actuation system for robotic applications. When coupled to a motor, a twisted string system acts as a high ratio rotary to linear motion convertor. This dissertation starts with a brief description of existing applications of twisted string mechanisms. Then, the first prototype of the twisted string actuation system, built for this research, is presented. The prototype was used for the development of a better understanding of the mechanism and to find its capabilities. Afterwards, and based on experiments performed with the first prototype, a two-phase twisted string actuation system that benefits from an overtwist phase is proposed. In this way, a higher contraction ratio compared to the state of the art could be achieved. Furthermore, since none of the previous mathematical models could predict the linear displacement of the system, for the overtwist phase, an improved mathematical model was developed that can accurately predict the linear displacement over the entire range of motion. Afterwards, the twisted string system was applied for the actuation of a robotic hand. The high contraction ratio that was achieved with the two-phase twisted string system, resulted in a compact and light rotary to linear motion conversion mechanism that could fit inside the palm of a robotic hand, which has around the same size of an adult human hand. Finally, there will be an overview of the most important achievements and conclusions of this research work, along with some future plans for further investigation.

Electrochemical machining is non-traditional machining which is commonly used to manufacture hard materials and to produce complicated shapes of irregular sizes in the product. In this paper, an experimental study is given for drilling AISI D2 tool steel. The focus of this study is to optimize machining parameters based on the Taguchi L9 orthogonal array approach to maximize material removal rate (MRR). Voltage, a concentration of the electrolyte, and gap width were selected as machining parameters of ECM (electrochemical machining) process. The signal to noise ratio (SN) and the analysis of variance (ANOVA) are statistical methods used to investigate the effects of machining parameters. As the results, the maximum MRR is 0.153 g/min obtained at voltage 48 V, electrolyte concentration at 150 g/l, and gap width at 1 mm. electrolyte concentration is the machining parameters that most influence the response.


In the article the perturbed inclusions with external perturbations are considered. The asymptotic properties of solutions sets of such inclusions are investigated.


The selection of most informative terms reduces the feature set and speed up the classification process. The most informative terms are highly affected by the correlative association of the terms. The rare terms are most informative than sparse and common terms. The main objective of this study is assigning a higher weight to the rare terms and less weight to the common and sparse terms. The terms weight are computed by giving emphasis on terms- strength, mutual information and strong association with the specific class. In this context, we proposed, a novel hybrid feature selection method named as, Correlative Association Score (CAS) of terms. The CAS utilizes the concept of Apriori algorithm to select the most informative terms. Initially, the CAS select most informative terms from the entire extracted terms. Subsequently, the N-grams of range (1,3) are generated from these informative terms. Finally, the standard Chi Square (χ2) method is applied to select most informative N-grams. The two standard classifiers Multinomial Naive Bayes (MNB) and Linear Support Vector Machine (LSVM) are applied on four standard text data sets Webkb, 20Newsgroup, Ohsumed10, and Ohsumed23. The promising results of extensive experiments demonstrate the effectiveness of the CAS in compared to state-of-the-art methods viz. Mutual Information (MI), Information Gain (IG), Discriminating Feature Selection (DFS), and χ2.

Magnetic cross‐relaxation spectra or Z‐spectra are presented for water, acetone, methanol, dimethylsulfoxide, and acetonitrile in cross‐linked bovine serum albumin gels. Each solvent studied, reports the same Z‐spectrum linewidth and shape for the solid component that follows from solutions of the coupled relaxation equations. The Z‐spectra demonstrate competition among solvents for specific protein binding sites. The rate of magnetization transfer in the rotationally immobilized protein environment is approximated by 1/T2 for the solid component, which is shown to account for the observed magnetization transfer rates in the systems studied. The temperature dependence of the Z‐spectra are different for water compared with the organic solvents. The cross‐relaxation efficiency in the organic solvents decreases with increasing temperature because molecules bind less well at high temperature. For water, the hydrogen exchange path becomes increasingly important relative to the whole molecule path with increasing temperature, which improves the net cross‐relaxation efficiency.

We analyze the problem of detecting a road target in background clutter and investigate the amount of prior (i.e. target specific) knowledge needed to perform this search task. The problem is formulated in terms of Bayesian inference and we define a Bayesian ensemble of problem instances. This formulation implies that the performance measures of different models depend on order parameters which characterize the problem. This demonstrates that if there is little clutter then only weak knowledge about the target is required in order to detect the target. However at a critical value of the order parameters there is a phase transition and it becomes effectively impossible to detect the target unless high-level target specific knowledge is used. These phase transitions determine different regimes within which different search strategies will be effective. These results have implications for bottom-up and top-down theories of vision.


Introduction Low back pain is a very common condition which is experienced by almost 70–80% of the population at some point in their life [1]. The major cause of low back pain in the working class population is primarily an intervertebral disc prolapse [2]. Of all the cases of a low backache only clinical significant low back pain accounts to only 4–6% [2]. Degeneration of the disc causes prolapse of the disc into the intervertebral foramina causing clinical signs and symptoms [2]. The surgical results depend on detailed history, physical and radiological examination so as to assess and confirm the real cause of back pain [2]. Surgical disc removal is a simple solution for patients with severe back pain with satisfactory results [3]. The traditional technique of extensive laminectomy and discectomy lead to extensive disruption of posterior stabilization structures and complications which followed later [3].

This paper presents a framework to develop and investigate location-based Virtual Reality (VR) applications. We demonstrate our framework by introducing a novel type of VR museum, designed to support a large number of simultaneous co-located users. These visitors are walking in a hangar-scale tracking zone (600 m), while sharing a ten times bigger virtual space (7000 m). Co-located VR applications like this one are opening novel VR perspectives. However, sharing a limitless virtual world using a large, but limited, tracking space is also raising numerous challenges: from financial considerations and technical implementation to interactions and evaluations (e.g., user's representation, navigation, health & safety, monitoring). How to design, develop and evaluate such a VR system is still an open question. Here, we describe a fully implemented framework with its specific features and performance optimizations. We also illustrate our framework's viability with a first VR application and discuss its potential benefits for education and future evaluation.


When it comes to taking the public transportation, time and patience are of essence. In other words, many people using public transport buses have experienced time loss because of waiting at the bus stops. We proposed a real-time vehicle tracking system using a global positioning system (GPS) technology module to receive the location of the vehicle. The buses will be tracked live with real time coordinates with this system. There will also be an android application which will give real time schedule of buses. Also it can give quick and real time replay for enquiry, via server. Also in case of bus failure or breakdown, the notification will be sent to system, with Bus location. In Bus Ticketing & Passenger Counting System plays most important role in today's life. User has no time to wait for bus and stand in bus queues. In our system user finds  bus location on map and checks passenger count information. This can be achieved using RFID. User can see list of buses on various routes with their arrival times.


Objective: To evaluate the therapeutic efficacy of retroviral-mediated HSV-tk/GCV system combined with radiotherapy on murine melanoma. Methods: By using retrovind-mediated gene transfer technique, hygromycin phospotrase-thymidine kinase fusion gene (hytk) was transferred into B16 murine melanoma cells. Antitumor effects were observed after γ-rays irradiation with 60Co rays as well as GCV treatment. Growth inhibition of melanoma models in C57BL/6 mice by HSV-tk/GCV systems in combination with radiotherapy was observed. Results: B16 cells transduced with hytk gene and treated with low concentrations of GCV, which showed little cytotoxicity alone, were highly sensitive to radiation. The sensitizer enhancement ratio (SER) was 1.62. This radiopsensitization was also obtained in vivo. Conclusion: The addition of retroviral-mediated HSV-tk/GCV gene therapy to standard radiation therapy an improve the therapeutic effectiveness for melanoma.


Organic adhesive – bonded wood board materials like particleboards, plywood and others are widely used in construction, furniture, car- making, etc. However, all materials made with organic adhesives release non-reacted toxic substances, in particular formaldehyde and phenol, which produce negative effects on human health during production and use. Current trend in wood processing industry is to replace organic binders used as adhesives by inorganic ones. One of such solutions to improve indoor air quality is to replace organic adhesives by inorganic ones and the use of the alkaline aluminosilicate binders of the system R2O-Al2O3-SiO2-H2O is a highly advantageous solution and no need of preliminary treatment of wood. Among disadvantages are the low elasticity. Among disadvantages of these binders restricting their use as adhesives are low elastic properties (high modulus of elasticity, stiffness) of the resulted wood-based products. The paper covers the results of modification of the alkaline aluminosilicate binders to improve properties using specially chosen organic additives – modifiers

We present a case of functional and histopathologic tolerance, chimerism, and spontaneous clearance of HBV in a patient four years after living donor liver transplant (LDLT). A 19‐year‐old male patient underwent a LDLT for HBV cirrhosis. He voluntarily ceased immunosuppression and antiviral therapy after 6 months. He is now four years status post transplant without any episodes of rejection or clinical manifestation of liver disease. PCR and VNTR were used to show donor‐recipient chimerism and a large degree of genetic similarity between the pair. MLC and cytokine elaboration were used to show recipient hyporeactivity towards donor antigen. He also has clinical evidence of clearing his HBV without continued use of HBIG. (Liver Transpl 2004;10:1432–1435.)


Gossan ore of sulfide zinc deposit contains abundant zinc, iron, and other metal elements, which is a significant resource with complex components and can be utilized. In this study, a new technology of preparing zinc ferrite from zinc sulfide deposit gossan was proposed. The effects of Al2O3, CaO, and SiO2 in gossan on the formation of zinc ferrite were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), and specific surface area and pore size analysis (BET). The results show that the presence of Al2O3 and CaO could hinder the formation of zinc ferrite, while silica had no effect on the formation of zinc ferrite. Under the conditions of the molar ratio of ZnO and Fe2O3 to Al2O3, CaO, and SiO2 of 1:1:1, an activation time of 60 min, and a roasting temperature of 750 °C for 120 min, the products, which had good crystallinity, smooth particle surface, and uniform particle size could be obtained. In addition, compared to the roasted products with Al2O3 and CaO, the specific surface area, pore volume, and pore size of the products with SiO2 were the largest.


The post mining soil has generally known for its high acid, poisonous compound and low macro nutrient concentration. (N, P, K, Ca, and Mg).  At this particular soil condition, many of the cultivation plants cannot grow well.  Therefore, a research needs to be conducted in order to repair the post mining soil condition by means of increasing the pH and macro nutrient concentration through calcification and litter addition.   This research had been done in November until December 2012 at the Agronomy Laboratory, Agriculture Faculty of The Mulawarman University used the Complete Random Design of Factorial (RAL) 2 x 5, with 3 times repetition.  The first factor was the Dolomite (D) with 2 levels (d 0 = 0 g dolomite/kg soil, and d 1 = 6,06 g dolomite/kg soil.  The second factor was the litter (T) with 5 levels (t 0 = 0 g/kg soil, t 1 = acacia litter ( Acacia Mangium Will) 100 g/kg soil, t 2 = Arachis pintoi litter Krapov. & W.C. Greg 100 g/kg soil, t 3 = seashore flower ( Wedelia trilobata  (L.) Hitchc) litter 100 g/kg soil and T 4 = sengon litter ( Albizzia Falcataria ) 100 g/kg soil.  This research used the Kailan plant ( Brassica oleraceae L. var acephala DC).   On the soil which had no dolomite, litter treatment A. Pintoi Krapov.&.K.C.Greg and sengon had positive impact on the pH increase, also for C-organic, N-total, and decreased the C/N value ratio, and Al 3+ content, followed by the seashore flower litter also influenced positively to the pH, C-organic, N-total increase, and decreased Al 3+ content.  Acacia influenced positively to the C-organic and N-total also, but negatively influenced the C/N ratio and Fe solubility.  The dolomite treatment with sengon litter gave additional height to the plants, leaves quantity and wide better than other treatment.


EBGSs, Electromagnetic Band Gap Structures, have been developed into the most prominent framework by virtue of their superior efficacy, less intricacy in fabrication, and unified integration with the monolithic microwave integrated circuits (MMICs). In this letter, a certain number of advanced designs of EBGS are introduced and characterized with some rigorous parametric studies. This epistle regards the planar-EBG frameworks in the fashion of conventional uniform circular, square, and annular ring patterns. By the same token, optimum Filling Factor has been investigated by exclusively analysing the traditional frequency response of band pass filter from three imperative aspects such as: initial stop band analysis, pass band analysis, and conclusive stop band analysis. In like manner, the parametric comparison has been demonstrated in view of the initial frequency response, selectivity, 3dB cut-off frequency, 3dB pass bandwidth, insertion loss at 2nd harmonics, and the insertion loss at 3rd harmonics to figure out the optimum filling factor for certain planar-EBG patterns.


A mid-story seismic isolated building has isolators at mid-story and it is a good candidate for seismic retrofitting. Elevators for mid-story seismic isolated buildings receive strong rail bending stress due to the floor gap at the isolated floor. To reduce rail stress, a new elevator system has been established that has a long rail support span at the isolated floor. But it has complicated dynamic behavior including large rail deformation and guide contact with the rail. To evaluate such dynamic responses, we developed a nonlinear finite element model. Simulation results were validated by experiments, with the model. After precisely checking the rail bending stress, we derived an optimal elevator design against earthquakes.

Abstract The Philippines has been on the news for five long months now due to a noisy, media savvy group of kidnappers that had abducted foreign hostages in April. During that period, we witnessed the spokesperson of the Abu Sayyafjoin the league of world leaders and experts in gaining precious airtime on CNN live. Local reporters as well were free to visit the kidnappers' lair by foot and air their interviews with them day after day. This would have been unthinkable in Malaysia or Singapore or even maybe Indonesia. However, the Philippine military later imposed a news blackout on its operations on Jolo Island where the kidnappers had encamped. Journalists who had been allowed to deliver soundbites on kidnappers were now banned from delivering the civilians' stories about the devastation of their province by the military. How exactly should media act in such a tough situation? What judgments should it make that would serve public interest and adhere to the fundamentals of a functioning democracy? This paper seeks to answer these questions.


where U,' (U:) are the forward and backward envelopes at fundamental (harmonic), 5 is distance in units of coupling strength at fundamental, T is a normalized time, and K~ and u2 are coupling and group-velocity ratios, respectively. The detunings 81,2 measure the distances from resonance (Bragg condition), being a,, 82/K2 = 1 (81, i j2/K2 = 1) on the lower (upper) branch of the relative bandgap edge (here we assume that the harmonic field is close to Bragg resonance with the grating second-harmonic). We apply a perturbation expansion of the fields u t 2 , which is valid when the variation of the interacting fields are dominated by a single Bloch wave [or eigenfunction of the linear problem in Eqs. ( l ) ] bordering either the upper or the lower branch of the gap edge.3 We are then able to characterize oneparameter families (bright-bright or darkdark) of symbiotic solitons with specific forms depending on the location of the carrier frequencies with respect to the two band edges. To assess the validity of the perturbative approach, we have resorted to numerical integration of Eqs. ( I ) on a finite stack of length 5 = S L with appropriate boundary conditions, using the soliton wave forms as initial condition in time (T = 0). In Fig. 1, we show the typical behaviors observed for bright-bright sech2-shaped solitons (supported close to both lower branches), when the two carrier frequencies lie deeply inside the gaps. The dispersive character of the propagation is clear. To the contrary, in the vicinityofthe bandedges (lSll, 182/~21+ 11, localization takes place. As shown in Fig. 2, the initial wave forms are preserved (the longer the grating, the weaker the oscillations), supporting our analytical arguments. In conclusion we have shown that mutual localization at two carrier frequencies occurs via SHG in a doubly resonant grating. We will discuss the experimental feasibility of trapping. *Fondazione Ugo Bordoni, Via B. Castiglione 59, 00142 Rome, Italy; E-mail:


100-300 IU Penicillin and 50 ug Streptomycin per ml medium are widely used for maintaining sterility in cell cultures. No adverse effects of these antibiotics on growth and differentiation of these cultured cells have been reported. We have investigated whether Penicillin, Streptomycin or Gentamicin interfere with total protein, DNA and the synthesis of sulfatide ( a component of myelin) in brain cell cultures of newborn mice after 6, 9, 12 days in culture. The combination of 200 IU Penicillin and 50 ug Streptomycin per ml as well as 50 ug Streptomycin per ml alone depressed total protein, DNA and sulfatide synthesis. Up to 300 IU Penicillin per ml or 50 ug Gentamicin per ml showed no effect on protein and DNA while there was a dose-dependent interference with sulfatide synthesis. Less than 100 IU Penicillin or 6 ug Gentamicin per ml did not even affect sulfatide synthesis. Since the antimicrobial activity is preserved even at lower concentrations, the recommended doses should be reduced to non-toxic levels. Dissociated brain cell cultures could possibly be used to study the effect of antibiotics or other drugs on growth and differentiation of brain cells in vitro. This might help to understand drug action and side effects in vivo.


Communal Internet access facilities or telecentres are considered a good way to provide connectivity to people who do not possess home connectivity. Attempts are underway to utilize telecentres as eLearning centres providing access to learning materials to students who would otherwise not be able to take up eLearning. This paper reports on the findings of qualitative interviews conducted with 18 undergraduate students from two Sri Lankan universities on their eLearning experiences using communal Internet access centres. The findings suggest that despite the efforts by telecentres to provide a good service to eLearners, there are various problems faced by students including: costs, logistics, scarcity of resources, connectivity speeds, excessive procedures, and lack of support. The experiences of these Sri Lankan students suggest that there is much that needs to be understood about user perspectives in using telecentres, which could help formulate better policies and strategies to support eLearners who depend on communal access facilities.

The topicality of the article is determined by the widespread use of blended learning approaches in higher education, especially in studying foreign languages. With the limited number of classroom hours proposed for teaching foreign languages at technical universities, it became very relevant to introduce various alternative out-of-class monitoring methods. The aim of the research is to investigate the effectiveness of introducing video sketches as the way to improve the process of foreign language studying at technical universities. The authors assume that recording video monologues could facilitate students' speaking abilities, reduce the level of their anxiety compared to delivering monologues in class and could stimulate the effective use of classroom hours for teaching foreign languages. To prove this hypothesis the authors of the study conducted an experiment in Peter the Great St. Petersburg Polytechnic University during the autumn term of 2019-2020 academic year with the total number of 232 participants randomly chosen from 1-course students of technical specialties with different levels of English language proficiency. The possibility to record a monologue instead of delivering it face-to-face was considered as the IV (independent variable) of the experiment. Such research method as an open-close questionnaire was used afterwards to identify the students' satisfaction with the proposed alternative as well as the analysis of the exam results at the end of the course. These results as the part of the students' academic performance represented the DV (dependent variable) of the experiment. The obtained data showed that students of the experimental group passed their exam significantly better than the students of the control group. Thus, the present survey proved that students of the experimental group would prefer to record video sketches instead of delivering monologues face to face and that making video monologues improved their fluency and helped overcome some psychological barriers. On the basis of the research and the results obtained during the experiment, the authors conclude that the application of video monologues in the process of teaching foreign languages is highly promising.

James Stirling's untimely death in 1992 cut short an immensely fruitful creative career which began in the 1950s. One of the most inventive - and controversial - British architects of the post-war period, Stirling came to international attention in the early 1960s with the completion of Leicester University Engineering Building - now recognized as a landmark in 20th-century architecture. This critical survey explores Stirling's early work, illustrating and analyzing 38 buildings and projects dating from 1950 to 1974. The book begins with an introduction assessing Stirling's early development and considering his place in the architecture of the time. The main body of the volume contains 670 drawings, plans and photographs supported by critical discussions of the projects which include residential buildings, student accommodation, academic institutions and industrial plants, interspersed with statements from Stirling himself.


A mathematical morphology method developed to analyze nuclepore membrane microimages automatically detects the nuclepore membrane structure so it can be used to detect possible forgeries of nuclepore membrane. The gray scale image was converted into a binary image using gray mathematical morphology. A delaminating detection method based on binary mathematical morphology detects the total number of nuclepores and the nuclepore radii. Experimental results demonstrate that the binary method not only effectively eliminates the noise and the varying background, but also retains the global nuclepore membrane information in the original gray image. The relative error of the total number of nuclepore is below 10%. The delaminating detection method also gives statistics on the nuclepore radii distribution. These fast mathematical morphology algorithms have many promising applications for equipment identification.


Let R be a commutative ring with identity. The purpose of this paper is to introduce two new classes of modules over R, called Ms modules and fulmaximal modules respectively. The first (resp. second) class contains the family of finitely generated and primeful (resp. finitely generated and multiplication) modules properly. Our concern is to extend some properties of primeful and multiplication modules to these new classes of modules.

The authors present a new scheme to realize global computation on massively parallel machines. This scheme uses asynchronous computation to provide powerful and fast global primitives. They rely on a formal model that can be used to effectively develop algorithms. The most promising application of this architecture is image analysis, that can rely on a cheap 2D mesh topology and provide an efficient implementation of most basic primitives.


This contribution makes a close analysis of the recent ECHR judgment in Maktouf and Damjanovic v. Bosnia and Herzegovina, which resulted in the release from prison of perpetrators of genocide at Srebrenica. The article examines ECHR cases on non-retroactivity, and traces their development in transitional cases back to the 'Berlin Wall cases'. Two main arguments are made: first it was not necessary to release the applicants in the Maktouf case, even though they won in Strasbourg, be- cause they only challenged their sentence rather than their guilt; and second, that the case can be situated in a complex transitional milieu where states, like Bosnia & Herzegovina, may ask for – but only occasionally receive – a form of 'transitional relativism'.

Different solvent extremes influences not only the speed of Sn reaction and also the reactive process and scale. The principle of Hughes-Ingold can be used to predict the influence of solvent on the reactive speed of Sn, but certain limitations exist.


Objective: Lung cancer is one of the most common cancers. Previous studies findings are not suitable to explain symptom experience and symptom management of Bangladeshi persons with lung cancer. This study was aimed to identify the symptom experiences and determines the management strategies among persons with lung cancer. Methods: A descriptive study design, using combined both quantitative and qualitative research methods, was chosen for this study. Convenient sampling was used to recruit 382 persons with lung cancer from two public and two private tertiary hospitals and 16 participants were invited for an in-depth interview in the qualitative part. Data collection was conducted from October 2015 to July 2016, using the MD Anderson Symptom Inventory Lung Cancer (MDASI-LC) questionnaire and using a semistructured interview guide to explore their symptom management strategies. The quantitative data were analyzed using descriptive and inferential statistics and qualitative data by content analysis. Results: Pain was the most frequently reported physical symptom and the most severe one, followed by sleep disturbance and fatigue. Psychological symptoms such as sadness and distress were also frequent. Participants also reported other symptoms that interfered with daily living in terms of mood, general activity, work, enjoyment of life, walking and relationships with others. The symptom management consisted of three categories, which were taking modern medicine, adopting complementary therapies, and cultivating mind and body balance. Most of the participants addressed uses of more than one strategy. Conclusions: Participants experienced several physical and psychological symptoms that interfered with their lives. This finding will be beneficial for health care personnel regarding clinical practice to manage symptoms and further research may be conducted to obtain proper interventions to alleviate symptoms, and improve quality of life.


A comparison of 39-MHz and 2450-MHz radiofrequency (RF) electrical treatments to control adult Sitophilus oryzae (L.) in hard red winter wheat revealed that the 39-MHz treatment was much more effective than treatment at 2450 MHz. Complete insect mortality was achieved by 39-MHz treatments that raised grain temperatures to 40°C; whereas, grain temperatures of ca. 80°C were required for complete mortality in 2450-MHz treatments. Insect mortalities from 39-MHz exposures were much greater 1 day after treatment than were those from 2450-MHz exposures producing comparable grain temperatures. The degree of injury and delayed mortality resulting from 39-MHz exposures also was much more severe than that resulting from 2450-MHz exposures. The results confirmed predictions, based on measurements of dielectric properties of adult rice weevils and wheat, that 39-MHz treatments should provide a much better opportunity for selectively heating the insects than would treatments at 2450 MHz.


automated feedback that helps them revise their work and ultimately improve their writing skills. These applications also address educational researchers' interest in individualized instruction. Specifically, feedback that refers explicitly to students'own writing is more effective than general feedback.3 Our discourse analysis software, which is embedded in Criterion (www.etstechnologies.com), an online essay evaluation application, uses machine learning to identify discourse elements in student essays. The system makes decisions that exemplify how teachers perform this task. For instance, when grading student essays, teachers comment on the discourse structure. Teachers might explicitly state that the essay lacks a thesis statement or that an essay's single main idea has insufficient support. Training the systems to model this behavior requires human judges to annotate a data sample of student essays. The annotation schema reflects the highly structured discourse of genres such as persuasive writing. Our discourse analysis system uses a voting algorithm that takes into account the discourse labeling decisions of three independent systems. The three systems employ natural language processing methods to extract essay-based features that help predict the discourse labels. They also use machine learning to classify the sentences in an essay as particular discourse elements. Our tool automatically labels discourse elements in student essays written on any topic and across writing genres.

Alternative Payment Models (APMs) piloted by the Centers for Medicare and Medicaid Services (CMS) such as ACO Realizing Equity, Access and Community Health (REACH) seek to improve care and quality of life among seriously ill populations (SIP). Days at Home (DAH) was proposed for use in this model to evaluate organizational performance. It is important to assess the utility and feasibility of person‐centered outcomes measures, such as DAH, as CMS seeks to advance care models for seriously ill beneficiaries. We leverage existing Accountable Care Organization (ACO) contracts to evaluate the feasibility of ACO‐level DAH measure and examine characteristics associated with ACOs with more DAH.


The theory of generalized linear models and quasi-likelihood provides a flexible framework for analyzing non-normal data. In this article, we demonstrate how this theory can be extended to include the analysis of discrete and categorical spatial data. This theory can be used to estimate parameters and test treatment effects in a designed experiment involving discrete or categorical spatial responses. It also provides a flexible method for spatial prediction using non-normal data and includes universal kriging and indicator kriging as special cases. Examples are given, including one where the focus is on comparing treatments in a designed experiment in which spatial correlation is present, and two others where spatial prediction or mapping is the desired goal. The methods presented here provide an additional set of tools for the analysis of spatial data that will be useful to researchers in a variety of disciplines, including hydrology, soil science, entomology, agronomy, and ecology.


On the basis of the structural dynamic optimization design theory,this paper investigates the structure of the composite pedestal of a typical submarine double cylinder shell with high transmission loss.To achieve the optimum vibration reduction,the exact sectional dimensions and positions of the rigid vibra tion isolation mass is first determined through preliminary optimization.Next,the rigid vibration isolation mass is equated with a bulb flat with the same section moment of inertia.By considering the restriction of the gross weight and the structural strength of dangerous sections,the structural dynamic optimization for mula is established.Basically,the objective function minimizes the average vibration acceleration of the non-pressure hull for all frequencies,and the design variables such as the hole radius and the pedestal de gree are carefully chosen.Results show that the composite pedestal with high transmission loss consider ably reduces the vibration noise in the medium-high frequency range,where the average vibration acceler ation of the non-pressure hull is decreased by 1.66 dB.

A new method for designing a wideband filtering power amplifier (FPA) is proposed in this paper, which utilizes multimode resonant cavities as input matching network (IMN) and output matching network (OMN) to realize the required complex impedance matching. This design method can not only achieve wide operational bandwidth with good return loss and compact circuit size, but also provide frequency selectivity with steep rejection skirt and high efficiency. For demonstration, a proposed wideband FPA at 3.5 GHz has been designed and simulated, which utilizes two triple-mode resonant cavities as its input and output complex impedance matching networks. EM-simulated results show it achieves an average gain of 17.5 dB with a fractional bandwidth of 21.5% (gain fluctuation $\lt1.5$ dB). The maximum power added efficiency (PAE) and saturation power can reach 63% and 40 dBm, respectively.


In an event of a pandemic influenza outbreak such as the great "Spanish Flu" of 1918 and the more recent 2009-2010 HINI "Swine Flu" scare, pharmaceutical as well as non-pharmaceutical resources are limited in availability and effectiveness. In this thesis we apply OR methods to evaluate the effectiveness of such resources and the strategies for reducing the number of infections resulting from an outbreak. In the first half of this work, we focus on epidemiological analysis of influenza modeling in a heterogeneous population. The majority of existing epidemiological literature models influenza spread in a statistically homogeneous population, but the model-based inclusion of heterogeneity by contact rate, susceptibility, and infectivity introduces significant effects on disease progression. We introduce a new discrete-time influenza outbreak model for a heterogeneous population and use it to describe the changes in a population's flu-related characteristics over time. This information allows us to evaluate the effectiveness of different vaccine targeting techniques in achieving herd immunity, that is, the point at which there is no further growth in new infections. In the second half of this work we switch to a practical application of OR methods in a pandemic situation. We evaluate the effectiveness of vaccines administered to US states during the 2009-2010 H1N1 pandemic. Since the US is geographically diverse and large, the outbreak progressed at different rates and started at different times in each individual state. We discuss dynamic, multi-regional, vaccine allocation schemes for large geographical entities that take into account the different conditions of the epidemic in each region and maximize the total effect of available vaccines. In addition, we discuss effective strategies for combining vaccines with non-pharmaceutical interventions such as hand-washing and public awareness campaigns to decrease the strain of an outbreak on the population.

In this paper, the first-principles calculations based on DFT were employd to investigate the elasticity characteristics of AgW20 alloy. The elasticity constants of the single crystals are calculated using the finite strain method and Voigt – Reuss – Hill (VRH) approach. The universal anisortropic index (AU ), shear anisortropic index, orientation dependency of Young's modulus, bulk modulus were used to characterize elasticity anisortropy behaviors. The calculated elasticity properties of AgW20 alloy show a remarkable elasticity anisortropy for AgW20 alloy.


Sisal bole rot disease is the major phytosanitary problem of Agave plantations in Brazil. The disease is caused by a cryptic species of Aspergillus: A. welwitschiae. To date, the only way to diagnose the disease was to observe external symptoms, visible only when the plant is already compromised, or through the isolation and sequencing of the pathogen, which requires cutting the entire plant for bole tissue sampling. We developed a new primer set based on a unique gene region of A. welwitschiae, which can detect the phytopathogenic strains through PCR directly from sisal leaves. Using the new marker to study the main sisal-producing areas in Brazil, we discovered a troublesome situation. The main producing areas of this crop had a pathogen incidence of 78%–88%. The dispersion index indicates a regular spatial pattern for disease distribution, suggesting that the use of contaminated suckers to establish new fields may be the main disease-spreading mechanism. Altogether, the high incidence of the pathogen, the unavailability of clean plants, the unpredictability of disease progression, and the low investment capacity of farmers reveal the vulnerability of this sector to a potential phytosanitary crisis. By correlating the disease symptomatology with soil nutritional traits, we suggest that higher potassium availability might decrease visual symptoms, while phosphorus may have the opposite effect. Also, we observe a potential cultivar effect, suggesting that common sisal may be more susceptible than hybrid cultivars (especially H400). This new molecular tool is a significant advance for understanding the disease, enabling the implementation of a monitoring program and studies that may lead to pathogen control strategies and changes in the Brazilian production model.


A monolithic very broad-band phase shifter has been designed and fabricated with a 0.2 micron HEMT technology. The architecture of this phase shifter is based on vector modulation. Measurements demonstrate the ability to shift the phase of the incoming signal from 0 to 360° at frequencies ranging from 100 MHz to 2 GHz.


It has been suggested by Noelken, Nelson, Buckley & Tanford (1965) that in rabbit IgG* the three fragments (two Fab fragments and one Fc fragment) are arranged as three compact globular entities joined by flexible regions of the heavy chains. Papain digestion (Porter, 1959) splits the molecule into these three fragments, whereas limited cleavage with pepsin (Nisonoff, Wissler, Lipman & Woernley, 1960) or CNBr (Cahnmann, Arnon & Sela, 1965) yields, after reduction, fragments that are similar to Fab fragment. Noelken et al. (1965) also suggested that the flexible region includes the disulphide bonds, between the two heavy chains, that could be reduced under very mild conditions (Palmer & Nisonoff, 1964). I now report the cleavage of rabbit IgG into three fragments by hydrolysis with trypsin; presumably cleavage takes place near one of the disulphide bonds in the flexible region. This was achieved after the conversion of the half-cystine residues into aminoethylcysteine residues by mild reduction and aminoethylation. Rabbit IgG (15mg./ml. in 0-15M-NaCI-0*2Mtris hydrochloride buffer, pH8-2) was reduced with various concentrations of dithiothreitol for 50min.


Growing plants of bread wheat (Triticum aestivum L. 2 n=6x=42, AABBDD) were subjected to acute or chronic irradiation by gamma-rays from 60Co and meiotic chromosome behaviours of PMCS in M1 generation were cytologically compared. Both acute and chronic irradiations produced different types of chromosomal aberrations at the meiotic stages. Among them, translocation type was the most frecluent, followed by univalent type. A mixed type, i. e. translocation accompanying one or more univalents was often detected. Even normal type which lacked translocation and univalent included laggards and briclges without exception. Other meiotic abnormalities such as deletion, iso-chromosome and micronuclei were observed frequently in both treatments. Dose dependency of translocation frequency was not recognized in this experiment. In chronic irradiation, different chromosome numbers and meiotic behaviours were found not only among florets of a spike but also among anthers of a floret. A number of plants with aneuploid-like grass types occurred at a high frecluency in M1, especially with low exposure.


Several aspects of breeding and soci/l behavior in two Galapagos finches are related to food supply. Geospiza fuliginosa is largely granivorous, and G. difficilis is largely insectivorous. Measurements show that breeding of both species occurred when arthropod abundance was high. Breeding stopped when arthropod abundance was declining but before it was low. Breeding-territory size in G. difficilis varied inversely with food supply. Territory size in G. fuliginosa was similar across sites and was not correlated with food supply. This difference between species may be attributed to differences in the effects of invertebrate and seed resources on the functional response of consumers: feeding rate of G. difficilis on inver- tebrates increased linearly with their supply, whereas feeding rate of G. fuliginosa on seeds was essentially independent of seed abundance. In the nonbreeding season, the granivore G. fuliginosa moved in flocks, whereas G. difficilis was more stationary and solitary. Data indicate that seed supply was temporally more variable than invertebrate abundance, and this helps account for dry-season behavioral differences between the species. Functional response and/or renewability of seeds and invertebrates may also have influenced behavior at that time. Received 18 April 1983, accepted 19 September 1983.


The purpose of this memo is to document our current best estimates of reservoir rock volume on the basis of microseismic, tracer, and hydraulic data. It is understood that this estimate is to be used in a heat transfer calculation, and thus must represent the effective volume from which heat will be extracted. The size estimates will attempt to account for the fact that not all rock stimulated during a hydraulic fracturing experiment is necessarily part of the swept volume when a steady state flow field is established between the wells.


Pulmonary hypertension (PH) is a pathophysiological disorder characterized by a vascular obstruction leading to increased right ventricular overload. It can be caused by multiple conditions that we classify into 5 clinical groups. PH is defined hemodynamically and the role and indications of cardiac catheterization are increasingly important. The subject includes a panoply of pathologies with great complexity at the same time physio-pathological, histo-etiopathogenic, genetic... which are gathered under one chapter: the pulmonary vascular pathology. Right heart catheterization (RHC) is crucial and allows to measure and calculate variables to determine patients hemodynamics that are necessary for positive, etiological and severity diagnosis. It can also have therapeutic purpose: vasoreactivity test (APVT), pre-gesture assessment. Materiel and Methods: retrospective cross-sectional study of 143 patients with suspicion of pulmonary hypertension whom underwent RHC (left heart) performed between January 2017 and December 2021 in cardiology A department within Ibn Sina university hospital center. Results: In terms of the results of our study, we have a very diverse review in which PH is assessed at different levels for all groups and subgroups using a multitude of hemodynamic parameters. Our population is characterized by a clear predominance of women The average age of all 143 cases is 38 years. In terms of hemodynamic classification, isolated pre-capillary PH is the most common (52%). 64% of our cases had PVRs >2 Wu indicating the prevalence of pulmonary vasculopathy. Group 3 represents the population with the most preserved hemodynamical severity parameters. The main vasoreactivity test performed was the NO test.


Bioreactor for cell culture fermentation is the main production equipment for precious pharmaceuticals and biological products, such as vaccines, monoclonal antibodies, enzymes, diagnostic reagents. In order to determine the status of cells, the traditional observation way which is adopted by pharmaceutical enterprise is removing partial media through the mouth of the liquid from the fermentation tank. But the growth status of cells cannot be discovered in real time by this way. In this paper, a method of non-contact observation by use of optical systems for the fermentation bioreactor of cells culture has been proposed. Illumination of the light window is opened above bioreactor liquid level of fermentation. And another observing the window is located below the fermentation liquid, it can tilt to observe the cells in the culture by use of long working distance micro optical system. By changing the focus position of the optical system, the purpose which observes the cells in the culture medium inside of the fermenting tank is achieved. The mobile mechanical structures of micro optical system and lighting system adopt fission design. A long working distance video microscope has been designed for observation, working distance is adopted by 80mm, the total length of the system is 417.69mm, the numerical aperture NA is 0.35, the object square line field is 0.65, and the optical resolution is 1micron and it can view the cells in the culture. Utilizing Gigabit net industrial CCD camera to acquisition image, the cells in bioreactor of fermentation have been automatic real-time monitored through processing and analysis of images in the computer. After the real-time observation, the growth of the cells in the whole fermentation tank can be probably understood. It can be accurately mastered the operation time of the process of cells' subculture, inoculation and receiving.

Hexapus anfractus (Rathbun) recorded from the Holocene Nanyo Formation is re-evaluated and identified with the extant species, Mariaplax chenae Rahayu and Ng.


Objective\ To evaluate the inhibitory effect of endostatin on the growth of LCI D20, a highly metastatic hepatocellular carcinoma. Methods\ Thirty nude mice were subcutaneously implanted with LCI D20 tumor tissues, then treated with subcutaneous injection of 2 mg·kg -1 ·d -1 (group EA) or 4 mg·kg -1 ·d -1 (group EB) Endostatin, or intraperitoneal injection of 1 mg·kg -1 ·d -1 cis-platin (group C), or 4 mg·kg -1 ·d -1 plus 1 mg·kg -1 ·d -1 cis-platin (group EC), or subcutaneous injection of 0.2 mg/d PBS as control. All treatment lasted 40 days after implantation. The tumor size was calculated by using the formula: V=L×W 2×0.52. Results\ The mean tumor size of each group was (8376±2129) mm 3 for the control, (6095±2261) mm 3 for group EA, (3777±2042) mm 3 for group EB, (1629±877) mm 3 for group C, and (1248±847) mm 3 for group EC, when measured on the day 40 after implantation. Statistical analysis showed that 2 mg·kg -1 ·d -1 Endostatin had no inhibitory effect on the growth of LCI D20, however, 4 mg·kg -1 ·d -1 Endostatin, 1 mg·kg -1 ·d -1 cis-platin and combination of these two drugs delayed the growth of LCI D20. Combination treatment increased the inhibitory effect on the tumor growth, as compared with Endostatin alone. Conclusion\ Antiangiogenic therapy inhibited the growth of hepatocellular carcinoma. Combination treatment improved the inhibitory effect.\;
