Subgraph-Indexed Sequential Subdivision for Continuous Subgraph Matching on Dynamic Knowledge Graph

Continuous subgraph matching problem on dynamic graph has become a popular research topic in the field of graph analysis, which has a wide range of applications including information retrieval and community detection. Specifically, given a query graph q , an initial graph G 0 , and a graph update stream △ G i , the problem of continuous subgraph matching is to sequentially conduct all possible isomorphic subgraphs covering △ G i of q on G i (= G 0 ⊕ △ G i ). Since knowledge graph is a directed labeled multigraph having multiple edges between a pair of vertices, it brings new challenges for the problem focusing on dynamic knowledge graph. One challenge is that the multigraph characteristic of knowledge graph intensifies the complexity of candidate calculation, which is the combination of complex topological and attributed structures. Another challenge is that the isomorphic subgraphs covering a given region are conducted on a huge search space of seed candidates, which causes a lot of time consumption for searching the unpromising candidates. To address these challenges, a method of subgraph-indexed sequential subdivision is proposed to accelerating the continuous subgraph matching on dynamic knowledge graph. Firstly, a flow graph index is proposed to arrange the search space of seed candidates in topological knowledge graph and an adjacent index is designed to accelerate the identification of candidate activation states in attributed knowledge graph. Secondly, the sequential subdivision of flow graph index and the transition state model are employed to incrementally conduct subgraph matching and maintain the regional influence of changed candidates, respectively. Finally, extensive empirical studies on real and synthetic graphs demonstrate that our techniques outperform the state-of-the-art algorithms.
Algoritmo Híbrido Para Estimação ML De Modelos HMM Baseado Em Treinamento De Viterbi E Otimização PSO

– A hybrid algorithm based on Viterbi Training and Particle Swarm Optimization (PSO) is here proposed to perform maximum-likelihood estimation of HMM models. A performance comparison with the Baum-Welch (BW) algorithm and with the PSO algorithm is presented, which is focused on the ability of the algorithms to search for the global solution. The numerical results obtained suggest that the proposed algorithm outperforms both the BW and the PSO algorithms.
Measurements of hydroxyl radical reactivity and formaldehyde in the atmosphere

Results from the laboratory characterisation of a new design of hydroxyl radical (OH) flow reactor are presented. Further to this details of its coupling with a gas chromatograph time of flight mass spectrometer (GC-TOF-MS) system, to form a new instrument for the identification of ‘missing’ OH reactivity is discussed. Preliminary measurements in ambient air demonstrated the potential value of this system which could be used to chemically identify ‘missing’ OH sinks in various environments, and also to determine bimolecular rate coefficients for their reaction with OH. Observations of OH reactivity and formaldehyde (HCHO) are presented from an urban background site in York in the summer of 2014. OH reactivity was measured using laser flash photolysis coupled with laser induced fluorescence spectroscopy (LFP-LIF). The average ‘missing’ OH reactivity was ~27 % when measurements were compared with values predicted by a calculation that utilised measured concentrations of a very detailed suite of volatile organic compounds (VOCs). It is concluded that a combination of unidentified VOCs and products of VOC photo-oxidation account for this discrepancy. HCHO was measured using a new fast response (1 s time resolution) laser induced fluorescence (LIF) spectroscopy instrument and some evidence of daytime diurnal behaviour suggested that the dominant HCHO source was photo-chemical (~1.3 ppb diurnal peak). Observations of OH reactivity and HCHO are also presented from a coastal site in Weybourne, Norfolk, using the same instrumentation during the summer of 2015. The average ‘missing’ OH reactivity was ~44 %. It is concluded that much of the ‘missing’ reactivity was likely due to unmeasured VOCs and their photo-oxidation products. Strong diurnal behaviour of HCHO was observed and is consistent with an atmosphere where the dominant source is photo-chemical (~1.1 ppb diurnal peak). Unusual behaviour was observed for HCHO during a thunderstorm where sharp fluctuations in concentration were observed. It has so far not been possible to conclude the exact cause of this, however, it is suggested that the source was marine. Finally, preliminary results from three experiments of an intercomparison of OH reactivity instrumentation are presented. The results demonstrate the reliability of the Leeds LFP-LIF instrument for the measurement of ambient OH reactivity.
Preliminary study to determine the maximum safe speed of vehicles based on rolling moments and vehicle skid to reduce of driving accidents

Indonesia is one of the countries with the highest death rate due to road traffic accidents. Research on vehicle safety needs to be done immediately. Some travel companies, rental vehicles, and tourism vehicles have made permit speed regulations, but the basis for selecting these limits is not scientific. In this study will be presented how to determine the maximum speed allowed in a vehicle scientifically, and how to calculate the speed of the permit can be a reference to other vehicles. This research method is analytical and experimental methods. The normal force of the wheel when the vehicle turns will be different, where the normal force of the wheel inside will first be lifted due to rolling force, and will have an impact on the skid that might occur. So, this is becoming a reference in calculating the vehicle’s maximum clearance speed. The maximum speed allowed of the vehicle under study depends on the turning radius. Therefore, knowing the wheel’s normal force from various conditions and the maximum speed of the vehicle, a safety warning system can be developed in the future to avoid vehicle accidents.

Physical Characterization and Drug Release Profiling for Hard Capsules Prepared with Hydroxypropylcellulose or Polyethylene Oxide

In this study, hard capsule shells were made by a heat-melting method, which involved heating Polyethylene oxide (PEO, MW 200000) or hydroxypropyl cellulose (HPC, MW 80,000, 100,000 and 370000) powder in a mold, followed by inserting a suitable size of pestle in a mold to coat the melted shell materials (HPC or PEO) onto pestle with a certain force. The more satisfactory were prepared at the temperature higher than melting point of corresponding polymer. The water uptake and dissolution test of various capsule shells were evaluated in acidic or basic buffer with added inorganic salt including sodium chloride, potassium chloride, calcium chloride and aluminum chloride. Propranolol hydrochloride and theophylline were selected as the model drugs. Propranolol hydrochloride released from various capsules was faster than that of theophylline due to the higher solubility of the former. There were no significantly different in the release rate in the formulation containing either microcrystalline cellulose (MCC, Avicel(superscript ®)) or lactose as diluents. Moreover, Release rate was decreased with increasing viscosity grades of HPC used as shell materials. Inorganic salt shows marked influence on the dissolution rate and the rate decreased with increasing concentration of salt in dissolution medium. The drug release from HPC capsules was greater affected by electrolytes than that from gelatin and PEO capsules.
Are maps of nitrate reduction in groundwater altered by climate and
land use changes?

Abstract. Nitrate reduction maps have been used routinely in Northern Europe for calculating efficiency of remediation measures and impact on climate change on nitrate leaching and are as such valuable tools for policy analysis and mitigation targeting. Nitrate maps are normally based on output from complex hydrological models, and once generated, are largely assumed constant in time. However, the distribution, magnitude and efficiency of nitrate reduction can not necessarily be considered stationary during changing climate and land use as flow paths, nitrate release timing and their interaction may shift. This study investigates the potential errors when a constant nitrate map is assumed during land use and climate change, both for N-loads and the spatial variation in reduction. For this purpose, a crop and soil model (Daisy) was setup up to provide nitrate input to a distributed hydrological model (MIKE SHE) for an agricultural catchment in Funen, Denmark. Nitrate reduction maps based on an observed dataset of land use and climate were generated and compared to nitrate reduction maps generated for all combinations of four potential land use change scenarios and four future climate model projections. Nitrate reduction maps were found to be more sensitive to changes in climate, leading to reduction map change of up to 10 %; while land use changes effects were minor. The study, however, also showed that the reductions maps are products of a range of complex interactions and that the combination of the choices made for selected scenarios, model formulations and assumptions are critical for the resulting span in reduction capability.
Occupational risk factors and preventive measures for COVID-19 in prosthodontics

Today, novel coronavirus infection has become pandemic worldwide. It is the major cause of sickness from the common cold to severe acute respiratory syndrome in individuals. In a dental operatory, infections can be expedited through several routes like aerosol generation, contaminated surfaces, droplet splatter, oral fluids, and direct contact. Keeping in mind about the routes of transmission of COVID-19 (Coronavirus disease-19), dental practitioners are at higher risk of exposure and disease spread. Hence, this review article emphasizes the routes of transmission, risk factors, prophylactic and preventive measures. It also sights on alternative approaches to prosthodontic procedures to reduce the burden of COVID-19 infection in their community. Data acquisition was made using the keywords, COVID-19, infection control, prosthodontic risk factors in electronic databases like PubMed, Medline, ProQuest, etc. A manual search of several journals and books was also carried out, and only highly relevant articles were considered for the present review.
Review on Recent Advancement of Therapeutic Interventions in Combating Multidrug Resistant Bacteria

Antibiotics is a class of drug that plays an eminent role in combating the deadly infections caused by harmful pathogenic organisms. However, irrational use of these antibiotics leads to multidrug resistance in bacterial species which in turn contributes to the morbidity and mortality worldwide, due to which they are referred to as superbugs. Thus, multidrug resistance is known as the resistance of a microorganism to different initially sensitive antibiotics. Though research has led to the development of new antibiotics and its derivatives, the development of new antibiotics is challenged at every step due to the emergence of microbial resistance. The emergence of drug resistance resulted due to the presence of Drug Resistant Plasmid, transposon, antibiotic resistant cassette and further the resistant phenotype can be transferred from resistant to a sensitive microorganism making sensitive organism resistant. Some bacteria acquire the property of being Multi Drug Resistant due to the presence of efflux transporter proteins which can expel antibiotics in a nonspecific manner and overcoming such medical emergencies is the demand of the era. Thus, the lack of novel antibiotics has created the need for certain technological tools to combat this deadly phenomenon. Among them, anti-microbial peptide, anti-virulence compounds, phage therapy, nanotechnology and CRISPR-Cas system are the most commonly used techniques to combat multidrug resistance. The present review highlights different multidrug resistance tools such as the application of Phage therapy, use of nanotechnology, CRISPR-Cas system and antimicrobial peptides together, their working mechanism, utility, efficacy, credibility and relevance along with the modifications needed in the techniques for improvisation.
Monitoring of high-moisture content particle drying in a fluidized bed by microwave and capacitance tomographic sensors

Abstract Particle drying in fluidized beds is a common and important process in food and pharmaceutical industry. However, the fluidization characteristic is complex due to the moisture content change in the process and it is a challenge to monitor the flow characteristics by conventional measurement approach, likes pressure and thermal probes. In this research, process tomography including capacitance and microwave tomographic systems are used to investigate the flow characteristics in a fluidized bed dryer with high-moisture content particles. Static tests were firstly carried out to investigate the image characteristics based on microwave tomography (MWT) and electrical capacitance tomography (ECT). The imaging ability was compared between MWT and ECT. In the dynamic tests, the drying process for particles with high-moisture content was monitored on-line by MWT and ECT separately. The static test results show that the high calibration for ECT is critical and particles with low moisture content should be used for high calibration of an ECT system to achieve high quality images for the dynamic tests. For the high calibration of ECT, there is an upper limit for the moisture content. With a fixed calibration background, the moisture content of particles should not exceed this upper limit value. MWT basically has no limitation on the moisture content both for high calibration and measurement. Dynamic test results illustrate that MWT is a good option to monitor high-moisture content particles drying in a fluidized bed and it is possible to combine ECT together to identify the gas–solids flow regime transit and to determine the moisture content by MWT in a fluidized bed drying process.
Impact of neoadjuvant chemoradiotherapy on post-operative outcome in patients with rectal cancer

Background: Neoadjuvant chemoradiotherapy not only helps in downstaging the rectal cancer, it also reduces the rate of local recurrence but it has its own attendant risk factors. Our aim is to look into the implications of neoadjuvant chemoradiotherapy in patients with rectal cancer in our hospital.Methods: Retrospective data was collected from the infoflex system of database for the patients who underwent neoadjuvant chemoradiotherapy between January 2016-December 2019 in our DGH. The data was analysed for demographics, type of surgery, histology, length of stay, complications and stoma reversal rates.Results: Total 27 patients with rectal cancer during the study period underwent neoadjuvant chemoradiotherapy. 16 were male and 11 females. Age range was 33-82 year. 13 patients underwent APER, 8 Hartmann’s and 6 anterior resection with covering loop ileostomy. 5 patients initially required defunctioning sigmoid loop colostomy and one loop ileostomy prior to the start of neoadjuvant treatment. Histology showed 26 adenocarcinoma, and 1 squamous cell cancer. 3 patients had complete pathological response (cPR). Post-operative stay was from 5-32 days. 12 patients developed pelvic collection, 5 wound infection (4 perineal+1 abdominal), 5 had paralytic ileus, 1 patient had PR bleed, 2 anastomotic leak and 2 patients had chest related complications. Only 4 out of 6 loop ileostomies were reversed. Conclusions: Neoadjuvant treatment benefits come with its attendant complications. The tissue response to radiotherapy and chemotherapy and advanced tumor stage may contribute for the increased morbidity. Hopefully in future with the advent of new armamentarium, the degree of morbidity may come down.
Job Marketable for Student with Disability: What We Should Know for Career Transition Programme

People with disabilities face the greatest challenge of getting a job. This is because of thelow marketability skills of this group. Career transition programme (CTP) has been introduced to students with disabilities (SWDs) to prepare and train them for job market.Skills training in the field of employment is provided to SWDs in the implementation of CTP. However, it is still difficult for this group to get a job despite having good skills.A survey study was conducted to identify the marketability skills required in planning and implementing CTP in schools. Four teachers in a secondary school in Selangor who have implemented CTP were selected as study participants. The data from interview were recorded and analysed thematically. Through the findings of this study, itshows the four main marketability skills required by SWDs namelybasic academic skills, emotional management skills, communication skills and self-management skills in ensuring a successful CTP. The findings also demonstrate that it is important to ensure that SWDs are ready to enter the job market. It is also valuable to reflect the good results from CTP.

Development of a Novel High-Temperature Al Alloy for Laser Powder Bed Fusion

The number of available materials for Laser Powder Bed Fusion is still limited due to the poor processability of many standard alloys. In particular, the lack of high-strength aluminium alloys, widely used in aerospace and automotive industries, remains a big issue for the spread of beam-based additive manufacturing technologies. In this study, a novel high-strength aluminium alloy for high temperature applications having good processability was developed. The design of the alloy was done based on the chemical composition of the widely used EN AW 2618. This Al-Cu-Mg-Ni-Fe alloy was modified with Ti and B in order to promote the formation of TiB2 nuclei in the liquid phase able to stimulate heterogeneous nucleation of grains and to decrease the hot cracking susceptibility of the material. The new Al alloy was manufactured by gas atomisation and processed by Laser Powder Bed Fusion. Samples produced with optimised parameters featured relative density of 99.91%, with no solidification cracks within their microstructure. After aging, the material revealed upper yield strength and ultimate tensile strength of 495 MPa and 460 MPa, respectively. In addition, the alloy showed tensile strength higher than wrought EN AW 2618 at elevated temperatures.
A Stakeholder Perspective on the Market Orientation of Swiss Nonprofit Organizations

ABSTRACT The adoption of business-like practices by nonprofit organizations (NPOs) has often been associated with focusing too much on markets, rather than mission. Yet, the concept of market orientation does not view profits as the goal, but rather as a consequence. This makes it highly relevant for NPOs. We argue that identifying, monitoring, and managing the relevant stakeholder groups through a market-orientation approach can enhance both the economic and social performance of NPOs. We do so by developing a preliminary scale of stakeholder-based market orientation based on survey data from Swiss NPOs and show that components of such a scale need to include stakeholder groups other than those found in the business literature. The effect of these components on organizational growth and mission achievement are examined using a structural equation model. The results suggest that adopting a stakeholder-based market orientation concept can have positive effects on organizational growth and mission achievement.
A Comprehensive Guide to select a Suitable Journal for Research Publication

Selection of suitable Journal for publication of research indings in a peerreviewed Journal is very critical and challenging for researchers. Selection of Journal for publication involves many factors, where the main factor is Journal metrics. In light of the proliferation of journals, some journals have come under increased scrutiny recently with terms such as questionable, illegitimate, dishonest, used to describe these journals. Generally, the young researchers or the irst-time authors, would like to publish their indings in a less reputed Journal with very less rejection rate, as theywant to publish their articles quickly. Wrong choice of journal for publishing spells outright rejection. Even if the article is very encouraging with sound and rigorous scholarly work, it will not stand the test. Another option for authors is to consult with librarians af iliated with organization or local public library. Librarians are well-suited to provide guidance in helping authorswith selecting quality journals to consider for publication. Transparency andobjectives are essential elements for scienti ic research and peer review process. Bibliographic software such as EndNote or RefWorks assist the authors to format reference section and to perform corrections suggested by reviewers. Hence, this review was delineated to provide an insight for the researchers to prefer a Journal based on the impact factor, H-index, SNIP, SJR and timeline of publication.
