Abstract:

Recently, object-oriented specifications of distributed systems has gained more attention. The object-oriented approach is known for its flexibility for system construction. However, one of the major challenges is to provide facilities for the dynamic modifications of such specifications during the development and maintenance process. Yet, current work has not addressed the dynamic modifications of specifications of distributed systems. In this paper, we are concerned with formal description techniques that allow for the development and dynamic modification of executable specifications. A two-level model for the evolution of large object-oriented specifications is introduced. The first deals with the dynamic modifications of types (classes), while the second deals with modifications of modules. We have defined a set of structural and behavioral constraints to ensure specification consistency after modification at both levels. To allow dynamic modification of types and modules, we have developed a reflective object-oriented specification language which uses meta-objects to support the modification operations. In this language, types and modules are objects.

Abstract:

Abstract DNA phosphorothioate (PT) modifications, with the nonbridging phosphate oxygen replaced by sulfur, governed by DndABCDE or SspABCD, are widely distributed in prokaryotes and have a highly unusual feature of occupying only a small portion of available consensus sequences in a genome. Despite the presence of plentiful non-PT-protected consensuses, DNA PT modification is still employed as a recognition tag by the restriction cognate, for example, DndFGH or SspE, to discriminate and destroy PT-lacking foreign DNA. This raises a fundamental question about how PT modifications are distributed along DNA molecules to keep the restriction components in check. Here, we present two single-molecule strategies that take advantage of the nucleophilicity of PT in combination with fluorescent markers for optical mapping of both single- and double-stranded PT modifications across individual DNA molecules. Surprisingly, PT profiles vary markedly from molecule to molecule, with different PT locations and spacing distances between PT pairs, even in the presence of DndFGH or SspE. The results revealed unprecedented PT modification features previously obscured by ensemble averaging, providing novel insights into the riddles regarding unusual target selection by PT modification and restriction components.

Abstract:

This paper presents an adaptive framework for processing a window-based multi-way join query over distributed data streams. The framework integrates distributed plan modification and distributed plan migration within the same scope by using a building block called the node operator set (NOS). An NOS is housed in each node that participates in the join execution, and specifies the set of atomic operations to be performed locally at the host node to execute its share of the global execution plan. The plan modification and migration techniques presented are for the case of updating the NOSs centralized at a single node and the case of updating them distributed at each node. The plan modification is triggered by the change of stream statistics and adjusts the join execution order and placement greedily to satisfy a cost invariant. The plan migration uses the distributed track strategy to accelerate the migration of window extents to new nodes. The migration of all window extents is synchronized. Experiments confirm the effectiveness of the developed adaptive framework on reducing the join execution cost and indicate a small additional adaptation-overhead for distributing the NOS update.

Abstract:

ZL111 alloy foams with a porosity of 80% and an average pore diameter of 3.5 mm were fabricated using a two-step foaming process, and the effects of modification and heat treatment on their microstructure and mechanical property were studied. The results indicates that by Y&Sr modification, most of the eutectic silicon in the ZL111 alloy foam is transformed from plate-like into dot-like forms, and the average size of evenly distributed α-Al grain is reduced from 80~100μm to 30~40μm, which is more efficient than separate Y or Sr modifications. By combining Y and Sr modification and T6 heat treatment, the α-Al grain size of ZL111 alloy foam maintains its previous modified effect, eutectic silicon remains spherical and well-distributed, and CuAl2and Al9FeMg3Si5are dispersed homogeneously at the α-Al grain boundary. The Y&Sr modification and T6 heat treatment also significantly improved the compressive property of ZL111 alloy foam, when we compared them with the untreated ZL111 alloy foam. The compressive strength rises from 13.3 MPa to 22.6 MPa, the densification strain improves from 59.3% to 76.9%, and the energy absorption capacity increases from 4.87 MJ/m3to 13.77 MJ/m3.

Abstract:

The grafting mechanism of KH570 in the nanometer ZnO/CeO2 composite powders is discussed. The influences of the reaction time, amount of coupling agent on the grafting rate are researched based on graft situation characterized with FT-IR and XRD devices. The research shows that the ZnO/CeO2 can be distributed evenly after be grafted with KH570. As a result, the performance of anti-UV and the lipophilic degree of modified nanometer ZnO/CeO2 will enhance. The modified nanometer ZnO/CeO2 will be distributed evenly in spinning solution while the spinning melted with NYLON 6 in high-temperature furnace. When the reaction time is 2 hours, the mass ratio of coupling agents and nanoparticle is 0.3, the grafting ratio can reach the maximum.

Abstract:

The DNA phosphorothioate (PT) modification existing in many prokaryotes, including bacterial pathogens and commensals, confers multiple characteristics, including restricting gene transfer, influencing the global transcriptional response, and reducing fitness during exposure to chemical mediators of inflammation. While PT-containing bacteria have been investigated in a variety of environments, they have not been studied in the human microbiome. Here, we investigated the distribution of PT-harboring strains and verified their existence in the human microbiome. We found over 2000 PT gene-containing strains distributed in different body sites, especially in the gastrointestinal tract. PT-modifying genes are preferentially distributed within several genera, including Pseudomonas, Clostridioides, and Escherichia, with phylogenic diversities. We also assessed the PT modification patterns and found six new PT-linked dinucleotides (CpsG, CpsT, ApsG, TpsG, GpsC, ApsT) in human fecal DNA. To further investigate the PT in the human gut microbiome, we analyzed the abundance of PT-modifying genes and quantified the PT-linked dinucleotides in the fecal DNA. These results confirmed that human microbiome is a rich reservoir for PT-containing microbes and contains a wide variety of PT modification patterns.

Abstract:

Creating a distributed and remote operated robotic system is a very challenging and time-consuming task. This paper contains the development issues taking into account when multiple robotic components are integrated to create a distributed robotic application using the standard middleware, Common Object Request Broker Architecture (CORBA) specification. The main idea is to define a set of generic interfaces using the Interface Definition Language (IDL) that can be used with common components in order to facilitate the integration of new components or the modification of them. The generic IDL interfaces are based on wrapper functions, which provide an abstract encapsulated behaviors of the low level components. The approach is shown using two types of arm manipulators and two different pan-tilt model units. Because of the modularity and the abstraction of this approach, this development can be seen as the first stage in constructing more autonomous and complex system.

Abstract:

Abstract Motivation Long-read sequencing technologies can be employed to detect and map DNA modifications at the nucleotide resolution on a genome-wide scale. However, published software packages neglect the integration of genomic annotation and comprehensive filtering when analyzing patterns of modified bases detected using Pacific Biosciences (PacBio) or Oxford Nanopore Technologies (ONT) data. Here, we present DNA Modification Annotation (DNAModAnnot), a R package designed for the global analysis of DNA modification patterns using adapted filtering and visualization tools. Results We tested our package using PacBio sequencing data to analyze patterns of the 6-methyladenine (6mA) in the ciliate Paramecium tetraurelia, in which high 6mA amounts were previously reported. We found P. tetraurelia 6mA genome-wide distribution to be similar to other ciliates. We also performed 5-methylcytosine (5mC) analysis in human lymphoblastoid cells using ONT data and confirmed previously known patterns of 5mC. DNAModAnnot provides a toolbox for the genome-wide analysis of different DNA modifications using PacBio and ONT long-read sequencing data. Availability and implementation DNAModAnnot is distributed as a R package available via GitHub (https://github.com/AlexisHardy/DNAModAnnot). Supplementary information Supplementary data are available at Bioinformatics online.

Ultrasonic vibration assisted electrical discharge surface modification was studied in the paper. The influence of ultrasonic vibration amplitude and frequency on the modification layer performance, such as surface roughness, sectional morphology, micro hardness and wear resistance was investigated. Experimental results show that ultrasonic vibration assisted electrical discharge surface modification can improve surface roughness and make the melting material well-distributed. The surfaces have higher micro hardness and wear resistance when the tool electrode is assisted with ultrasonic vibration.

Abstract:

The mechanical properties of dental acrylic resins have to be improved in the case of a thin denture plate. This can be achieved by cellulose addition, playing the role of active filler. But to provide the excellent dispersion of cellulose microfibres within the hydrophobic polymer matrix, its surface has to be modified. Cellulose microfibres with average length from 8 to 30 μm were modified with octyltriethoxysilane and (3-methacryloxypropyl)methyldimethoxysilane. The latter also participated in the polymerisation reaction of methyl methacrylate. Dental composites were prepared following the general procedure provided by the supplier. The successful modification of the microfibres led to the improved compatibility of the cellulose and poly(methyl methacrylate). The fibres after modification were uniformly distributed within the matrix, resulting in the improved mechanical performance of obtained materials. Cellulose microfibres are good candidates for the dental materials to be used as the active filler. The simple and straightforward approach for the cellulose modifications with silanes provides good potential for its future practical application.

Abstract:

Search engines use crawlers to traverse the Web in order to download web pages and build their indexes. Maintaining these indexes up-to-date is an essential task to ensure the quality of search results. However, changes in web pages are unpredictable. Identifying the moment when a web page changes as soon as possible and with minimal computational cost is a major challenge. In this article we present the Web Change Detection system that, in a best case scenario, is capable to detect, almost in real time, when a web page changes. In a worst case scenario, it will require, on average, 12 minutes to detect a change on a low PageRank web site and about one minute on a web site with high PageRank. Meanwhile, current search engines require more than a day, on average, to detect a modification in a web page (in both cases).

Abstract:

Effects of Sr levels on microstructure of the LPSO structure-containing Mg98.5-xNi0.5Y1.0Srx(x=0, 0.05, 0.10, 0.20 at.%) alloy were studied by SEM/EDS and XRD. Without Sr addition, the Mg98.5Ni0.5Y1.0alloy consists of α-Mg and LPSO structure and the block LPSO structure is distributed along the grain boundary. After adding 0.05 at.% Sr element into Mg98.5Ni0.5Y1.0alloy, the amount of dendrites decreased. With the increase of Sr content, the size of α-Mg grains decreases firstly and then increases. Meanwhile, the LPSO structure is refined. The addition of Sr element also results in the obvious increment of the amount of lamellar structure, which stretched from the grain boundary to the matrix. The excessive Sr in high Sr-content alloys participates in the form of Mg-Ni-Y-Sr compound, which is distributed in the vicinity of LPSO structure. In addition, the Sr can also promote the formation of Ni-rich and Y-rich phases.

Abstract:

Layered lithium transition metal oxides are widely used as cathodes in lithium-ion batteries and are continuously being developed to provide more energy. Here, the synthesis and structure of Li(Ni0.33Mn0.33Co0.33)O2, ‘Li0.9K0.1(Ni0.33Mn0.33Co0.33)O2’, and ‘Li0.9Cs0.1(Ni0.33Mn0.33Co0.33)O2’ are characterised in detail and compared with similar studies in the literature. Structural models are evaluated based on the statistical quality of fitting via the Rietveld method with X-ray diffraction data and the use of a range of starting structural models. Critically, this work highlights that the larger alkali atoms do not dope on to the Li sites but rather are likely to be distributed on the surface of the particles which is also evidenced with electron microscopy. This work showcases that care must be taken by researchers when using such doping regimes and the concentration of the dopants.

Abstract:

Content networks are overlay networks, enabling access to distributed contents on centralized servers or individual computers. Since flooding-based routing scheme features poor scalability, we present a modification, which reduces the total network traffic while retaining the original efficiency. In choosy routing, as we call it, each node, while passing an answer, remembers which neighbor it came from. Subsequently repeated queries about the same content are forwarded only to that neighbor. This way, the network learns effective routes. The simulations on several topology types have shown the expected behavior, with up to three-fold reduction in the overall query traffic.

Abstract:

Modified Distributed Arithmetic Concept for Implementations Targeted at Heterogeneous FPGAsDistributed Arithmetic (DA) plays an important role in designing digital signal processing modules for FPGA architectures. It allows replacing multiply-and-accumulate (MAC) operations with combinational blocks. The quality of implementations based on DA strongly depends on efficiency of methods that map combinational DA block into FPGA resources. Since modern FPGAs have heterogeneous structure, there is a need for quality algorithms to target these structures and the need for flexible architecture exploration aiding in appropriate mapping. The paper presents a modification of DA concept that allows for very efficient implementation in heterogeneous FPGA architectures.

Full text

Abstract:

Protein identification is an integral part of proteomics research. The available tools to identify proteins in tandem mass spectrometry experiments are not optimized to face current challenges in terms of identification scale and speed owing to the exponential growth of the protein database and the accelerated generation of mass spectrometry data, as well as the demand for nonspecific digestion and post-modifications in complex-sample identification. As a result, a rapid method is required to mitigate such complexity and computation challenges. This paper thus aims to present an open method to prevent enzyme and modification specificity on a large database. This paper designed and developed a distributed program to facilitate application to computer resources. With this optimization, nearly linear speedup and real-time support are achieved on a large database with nonspecific digestion, thus enabling testing with two classical large protein databases in a 20-blade cluster. This work aids in the discovery of more significant biological results, such as modification sites, and enables the identification of more complex samples, such as metaproteomics samples.

Abstract:

Structural features and dielectric behavior of polymeric systems based on tetrazole are investigated after combining them with potassium nitrate (KNO3) and potassium chloride (KCl). It was found that the salt additives added to the system exist in the form of the singular crystallites that is the closed inclusions chaotically distributed inside polymeric matrix. Injection of potassium nitrate increases the value of dielectric permittivity on the studied interval of frequencies. Potassium chloride reduces the value of dielectric permittivity of the polymeric system in the field of high frequencies, and increases it in the field of low frequencies. Addition of salt increases the specific conductivity of composites that indicates increase in degree of dissociation of ionogenic substances. In the studied systems, ionogenic substances, besides salt additives, including water and remains of catalysts.

Abstract:

A novel method for modification of the polymer cladding of an optical fiber has been developed for use in distributed chemical sensing. The usefulness of the new technique is illustrated by means of a distributed sensor for ammonium ions based on a 9 m long plastic-clad silica fiber modified with phenol red. The stability of the immobilized indicator made it possible, for the first time, to use a chemically modified fiber for the reversible detection of ammonium ions in highly alkaline solution (pH 11–14). The new sensor offers a broader dynamic range (four orders of magnitude) and shorter response time (30 s) than point sensors for ammonium ions reported in the past.

Abstract:

This manuscript deals with the situation in which the different agents or buses in a power network have access to local renewable resources and must manage its use in a distributed fashion. The buses distributedly decide the amount of power to be generated using their local renewable power plants, and that to be demanded from the grid. The decisions are made according to the optimization of a cost function that considers both economic and technical factors. The problem is approached resorting to a game-theoretical framework that requires a negotiation process among the neighboring buses. An iterative algorithm is proposed in order to solve this problem, providing existence and convergence conditions under which the buses reach a suitable equilibrium. The algorithm performance is tested in simulations over a modification of the IEEE 14-bus system, in which the lines are modeled as resistances and distributed generation is considered. Simulations on a network of 44 buses are also included to show the scalability of the method.

Abstract:

In this paper a novel distributed algorithm for blind macro-calibration in sensor networks based on consensus is proposed. The algorithm is formulated as a set of gradient-type recursions for estimating parameters of sensor calibration functions, starting from local criteria defined as weighted sums of mean square differences between the outputs of neighboring sensors. It is proved that the algorithm achieves asymptotic agreement for sensor gains and offsets in the mean square sense and with probability one. In the case of additive measurement noise, additive inter-agent communication noise and communication outages, a modification of the original algorithm is proposed. It is proved using stochastic approximation arguments that the modified algorithm achieves asymptotic consensus for sensor gains and offsets in the mean square sense and with probability one. Special attention is paid to the situation when one sensor is selected as a reference. Illustrative simulation examples are provided.

Abstract:

This study investigates a method of calculating tooth modification amount of a wind-turbine gearbox. The requirements of high reliability and a service life of 20 years or longer for wind power gearboxes necessitate appropriate gear meshes, which require elaborate tooth modification. The interference between teeth caused by deformation of the gear body and the shaft alignment error, which is caused by deformation of system components such as the housing, the bearings, and the shaft, was calculated, and the result was used to determine the tooth modification parameters. Thus, a method of calculating tooth modification amount was developed that can be performed without trial and error; its reliability was confirmed by an evaluation through simulation. Contact was evenly distributed over the tooth surfaces after the tooth profile was corrected, thus improving the edge contact pattern relative to the situation before correction.

Abstract:

The aim of this work was to evaluate the effect of thermal modification on surface hardness and depressions by applying loads to obtain floors for low traffic environments. Four clones were used from which logs were obtained and split into boards dried in time, and grouped for testing in their natural condition (NT) and thermally modified at 200 degrees Celsius for four hours (T) in a schedule with a heating of 1 degree per minute, on electric oven. Then in the samples from each clone were evaluated the mass loss, specific gravity, lignin and holocelluloses content, Janka hardness, fall ball impact depressions, distributed load depressions, and concentrated load depressions using track equipment which transfer a load of 890N to the woods at a speed of 0.06 ms-1. In the results verified high mass loss in the E. grandis x E. urophylla clone from controlled polination. The lignin contents showed increases and holocelluloses contents showed significant decreases after thermal modification. There was a reduction in Janka hardness in the woods with the exception of E. urophylla clone which presented lower depressions in the fall ball test after thermal modification. Verified increasing in depressions in the concentrated and distributed load tests, after thermal modification. And the E. urophylla clone presented lower depressions after 25 and 50 passes respectively, being the most recommended for obtaining floors for saunas, garden decks, swimming pools as it does not require high loading requirements.

Abstract:

We claim that a dynamic agent infrastructure can provide a shift from static distributed computing to dynamic distributed computing, and we have developed an infrastructure to realize such a shift. We shall compare this infrastructure with other distributed computing infrastructures such as CORBA and DCOM, and demonstrate its value in highly dynamic system integration, service provisioning and distributed applications such as data mining on the Web. The infrastructure is Java-based, light-weight, and extensible. It differs from other agent platforms and client/server infrastructures in its support of dynamic behavior modification of agents. A dynamic agent is not designed to have a fixed set of predefined functions, but instead, to carry application-specific actions, which can be loaded and modified on the fly. This allows a dynamic agent to adjust its capability to accommodate changes in the environment and requirements, and play different roles across multiple applications. The above features are supported by the light-weight, built-in management facilities of dynamic agents, which can be commonly used by the "carried" application programs to communicate, manage resources and modify their problem-solving capabilities. Therefore, the proposed infrastructure allows application-specific multi-agent systems to be developed easily on top of it, provides "nuts and bolts" for run-time system integration, and supports dynamic service construction, modification and movement. A prototype has been developed at HP Labs and made available to several external research groups.

Abstract:

Objectives – Various efforts are being made to disseminate lifestyle modification information. What is the role of health information in building patients self-efficacy in lifestyle modification? The research examined level of access to lifestyle modification information for patients with chronic diseases in two Federal Government Teaching Hospitals in South East Nigeria. It explored the relationship between self-efficacy and access to lifestyle modification information and also factors that are associated with self-efficacy when patients have access to lifestyle modification information. Methods – The research is a cross-sectional correlation study that used a questionnaire to collect data. (See Appendix A.) Sample was 784 patients with chronic diseases. Questionnaires were distributed to the patients as they attended clinics in the medical and surgical outpatients’ clinics of the hospitals. Results – Findings showed access to lifestyle modification information was significantly and positively correlated with self-efficacy. Multiple Regression analysis suggest that age, type of illness, and length of treatment in the teaching hospitals were associated with self-efficacy when patients have access to lifestyle modification information. Conclusion – It will be pertinent that demographic and disease factors are considered when making lifestyle modification information available to patients for greater self-efficacy.

Abstract:

The microstructure of non-combustible magnesium alloy, AMX602, was modified by friction stir processing (FSP) at the tool rotational speed of 800 rpm and traveling speed of 300 mm/min. In the microstructure of the as-extruded material, some intermetallic compounds (IMCs), Al2Ca and Al-Mn, inhomogeneously distributed in the matrix. The inhomogeneity was dependent on the extruding condition. The largest size of IMCs was a few tens microns. By FSP, large IMCs were broken up, and fine IMCs were uniformly dispersed in the matrix. Furthermore, grain refinement occurred due to dynamic recrystallization.

Abstract:

Anxiety disorders comprise persistent, disabling conditions that are distributed across the globe, and are associated with the high medical and socioeconomic burden of the disease. Within the array of biopsychosocial treatment modalities—including monoaminergic antidepressants, benzodiazepines, and CBT—there is an unmet need for the effective treatment of anxiety disorders resulting in full remission and recovery. Nutritional intervention may be hypothesized as a promising treatment strategy; in particular, it facilitates relapse prevention. Low-carbohydrate high-fat diets (LCHF) may provide a rewarding outcome for some anxiety disorders; more research is needed before this regimen can be recommended to patients on a daily basis, but the evidence mentioned in this paper should encourage researchers and clinicians to consider LCHF as a piece of advice somewhere between psychotherapy and pharmacology, or as an add-on to those two.

Abstract:

Considering the practical problems of gear noise and vibration, this work focuses on the gearbox of the electric vehicle as the research object to analyse the impact of gear micro-tooth modification. First of all, the effort centres itself on minimising the contact stress and making the load distribution better by implementing the tooth modification on both upper and central speed phases. The procedural analysis of gear tooth modification is executed to make the contact pattern better, so edge contact has been avoided and the load is distributed over a wide area of the tooth for both upper and central gear sets. The contact pattern is positioned in the centre of teeth and contact stress is lowered by 20% to 837 MPA. Then, the peak to peak transmission error is decreased under three proposed modification approaches. Also, contact and bending safety factors are improved as a result of tooth modification. Meanwhile, it was noticed by performing dynamic analysis that right bearings of both upper and central phases have a higher radial response for first two orders which is further decreased to an optimum level as a result of micro-tooth modification strategies.

Abstract:

To solve the problem of collaborative engineering changes of models distributed in heterogeneous design platforms, a “model to model” perception methodology is proposed in this paper. A self-management collaborative architecture is presented by peer to peer architecture and multiagent system. The network addresses correlation between heterogeneous platforms is built up by the perception router ontology. In the same way, the correlation between design models is described by the feature relation ontology. The design changes are encapsulated by the model modification ontology. Along with the ontology above, the design change search method is devised to catch the geometric changes; the influence search method is proposed to discover the influenced design feature and the design change adapting method is used to preserve the correlation coherence after perception. Through the work, the conventional design perception mode among designers has transformed into direct perception among models instead.

Abstract:

A significant amount of polystyrene sulfonated acid (PSSA) and poly(styrene-ran-acrylic acid) (PSAA) random copolymer can be adsorbed by dispersion of PS particles via a swelling-quenching process. A THF-water mixed solvent was used in the swelling process and a large amount of pure water was used, to give a low concentration of THF% in quenching process. Our results showed that functional PSSA groups were randomly and tightly adsorbed to the PS particles. When the mol.% of charged segments was increased, the progressive adsorption of PSSA chains to the PS particles leads to an increase in the electrophoretic mobility and zeta-potential of aqueous dispersions. Thus, we were able to obtain well-distributed surface charge density on the PS particles.

Abstract:

The microstructures and dry sliding wear behavior of Al-17Si cast alloys were studied after various melt treatments such as refinement and modification. Results indicate that combined refined and modified Al-17Si cast alloys have microstructures consisting of uniformly distributed primary silicon and fine eutectic AlSilicon particles through out the matrix. These alloys exhibited better wear resistance in the cast condition compared with the same alloy subjected to only refinement or modification. The improvements in properties observed in the present studies are mainly due to the structural differences between the refined, modified or both refined and modified over just cast Al-Si alloys. This paper attempts to investigate the influence of the microstructural changes in the Al-17Si cast alloys by refinement, modification and combined action of both on the dry sliding wear behavior.
