Improved perturbation technique privacy‐preserving rotation‐based condensation algorithm for privacy preserving in big data stream using Internet of Things

Several concerns are raised due to the widespread technology of Internet of Things and big data, which possess private and protection of information. Several researchers have analyzed different privacy preserving techniques, which still cannot provide equal stability between the data privacy and the utility and improvement in the scalability and efficiency. Data mining is one of the prominent technologies, which extracts reliable and useful knowledge from vast amount of information. Henceforth, mining of data stream have become a most popular and important research issue. Due to fast growth in the data generation, the mechanism of privacy preserving with high utility and security becomes more necessary. In this research, an improved efficient perturbation method for data stream named privacy‐preserving rotation‐based condensation algorithm with geometric transformation is proposed that delivers high data utility when compared with other existing techniques. This improved method gives high resilience against the attacks during the process of data reconstruction. Simulation result shows that the proposed method can acquire data privacy and improves accuracy during mining of data streams in which the analysis is performed for different datasets in which the proposed technique obtains more than 95% when compared with original dataset.
Crassulacean acid metabolism in the epiphytic ferns Drymoglossum piloselloides and Pyrrosia longifolia: studies on responses to environmental signals

Abstract The paper reports the results of the comprehensive study of crassulacean acid metabolism in two epiphytic tropical ferns, Drymoglossum piloselloides and Pyrrosia longifolia. The plants were investigated under different light, temperature and water status. It was found that both species are obligate CAM plants. The diurnal acidity rhythm is due to the fluctuation in malic acid concentration, which accounts for the change in titratable acidity. Besides malic acid, shikimate and oxalate are found to be present, but not contributing to the CAM acid rhythm. The diurnal rhythm of malic acid content results in a corresponding rhythm in leaf water relations. Both ΦΦ and Φtotal, were lowest at the end of the night, i.e. when the level of malic acid was highest. The effects of temperature on CO2 exchange were inverse to those observed in other CAM plants. In both ferns studied, dark CO2 fixation increased when the night temperature was increased. Increase in day temperature reduced CO2 uptake during phase IV and during the following night. The observed responses of the ferns to temperature changes suggest that the in situ environmental conditions are optimal for their CAM performance. In weak light, the plants showed net CO2 output during the midday deacidification period. Increases in light intensity reduced such CO2 output. Under drought conditions, the CO2 exchange in the ferns was reduced to zero within 5–6 d, indicating that the ferns studied are more susceptible to water deficiency than other CAM plants. This could be due to a higher cuticular conductance for water. The results are discussed, in particular, in relation to CAM performance of epiphytes growing in the wet tropics.
Effects of Six Levels of Dietary 17α-Methyltestosterone on Sex Reversal and Growth of Oreochromis aureus (Steindachner) and O. niloticus (Linnaeus)

The effects of six levels (0, 5, 10, 15, 20, and 25 ppm) of dietary 17α-methyltestosterone (MT) on sex reversal and growth of Oreochromis aureus (Steindachner) and O. niloticus (L.) were evaluated. Fifteen ppm MT produced 100% male populations in both species. Both MT-treated and untreated O. niloticus grew significantly faster than their O. aureus counterparts (P<0.05).
Using Non-linear Controller in Peer to Peer Energy Trading Between Distributed Generations

This paper presents a nonlinear control strategy for distributed generation in Microgrids based on synchronism machine. A nonlinear controller is proposed to compensate the nonlinear characteristics of the droop behavior of load angle, frequency and real power. The structure of the proposed controller doesn't need to change during the Microgrid's mode changing. This helps to overcome the issues such as undiagnosed areas and time delays during the detection of the island mode. This system is stable during the transition to the island mode as well as in case of a sudden disturbance. The scheme of controller is proposed via two steps; first, the parameters associated to a linear control drop have been set and in the next step, a nonlinear controller corresponding to the linear one is designed to ensure the overall stability of the microgrid in both grid-connected and islanding modes.
Outcomes of a single-step endoscopic ultrasound-guided drainage of pancreatic-fluid collections using an electrocautery-enhanced coaxial lumen-apposing, self-expanding metal stent with and without fluoroscopy

Abstract Background Fluoroscopy is often used during the endoscopic drainage of pancreatic-fluid collections (PFCs). An electrocautery-enhanced coaxial lumen-apposing, self-expanding metal stent (ELAMS) facilitates a single-step procedure and may avoid the need for fluoroscopy. This study compares the treatment outcomes using ELAMS with and without fluoroscopy. Methods Patients with PFCs who had cystogastrostomy from January 2014 to February 2017 were enrolled. Two groups were studied based on fluoroscopy use. Technical success was defined as uneventful insertion of ELAMS at time of procedure. Clinical success was defined as (i) clinical resolution of symptoms after the procedure and (ii) >75% reduction in cyst size on computed tomography 8 weeks after stent placement. Adverse events including bleeding, stent migration, and infection were recorded. Results A total of 21 patients (13 males) had PFCs drainage with ELAMS in the study period. The mean age was 51.6 ± 14.2 years. Thirteen patients had walled-off necrosis while eight had a pancreatic pseudocyst. The mean size of the PFCs was 11.3 ± 3.3 cm. Fluoroscopy was used in seven cases (33%) and was associated with a longer procedure time compared to non-fluoroscopy (43.1 ± 10.4 vs 33.3 ± 10.5 min, P = 0.025). This association was independent of the size, location, or type of PFCs. Fluoroscopy had no effect on the technical success rates. In fluoroless procedures, the clinical resolution was 91% as compared to 71% in fluoroscopy procedures (P = 0.52) and the radiologic resolution was 57% as compared to 71% in fluoroscopy procedures (P = 0. 65). Three cases of stent migration/displacement occurred in the fluoroless procedures. Conclusions ELAMS may avoid the need for fluoroscopy during cystogastrostomy. Procedures without fluoroscopy were significantly shorter and fluoroscopy use had no impact on the technical or clinical success rates.
Laver (Porphyra spp) and soy protein concentrate as alternative proteins in diets for juvenile Atlantic cod, Gadus morhua

Fishmeal is the main ingredient in formulated fish feeds, and the cost of this commodity is the largest and most volatile recurrent expenditure by the finfish aquaculture industry. Additionally, the reliance on wildharvested forage species raises concerns about the industry's ecological impacts. Marine macroalgae and soyderived feed ingredients both have merits as alternative proteins for piscivorous marine fish. Atlantic cod, in particular, have a highly adaptable digestive system and perform well with alternative protein diets. Atlantic cod, Gadus morhua, juveniles (initial body weights: 15.6 g, 87.9 g, and 15.92 g) were fed isonitrogenous, iso-caloric diets to evaluate two alternative proteins. In the first experiment, purple laver (Porphyra spp.) replaced 0%, 15%, or 30% of the fishmeal in a commercially available marine finfish diet. In the second experiment, diets contained soy protein concentrate (SPC) to provide 0%, 10%, 20%, 30% or 40% dietary soy protein or to replace 0%, 25%, and 50% of the fishmeal in a commercially available diet for marine finfish. No differences in survival, growth, or hepatic-somatic indices were found among any of the treatment groups. The fish attained an average weight of 41.0 g with a specific growth rate (SGR) of 1.19% and a feed conversion ratio (FCR) of 1.26 in the first experiment. In the second experiment, the fish attained average weights of 162.7 g in the first trial and 39.1 g in the second trial with SGRs of 0.76% and 1.12% and FCRs of 1.28 and 1.29, respectively. These results indicate that soy protein concentrate can entirely replace fish meal in diets for juvenile Atlantic cod. Additionally, SPC or Porphyra can be combined with other common feed ingredients to replace dietary fishmeal by at least 50% or 30%, respectively.
Inbreeding is reduced by female-biased dispersal and mating behavior in Ethiopian wolves

Molecular tools have enabled wildlife researchers to obtain accurate information on the kinship, mating behavior, and dispersal of individuals. We genotyped 192 Ethiopian wolves (n e 29 packs) in the Bale Mountains for 17 microsatellite loci to 1) elucidate kinship within and between packs, 2) assess parentage of pups, and 3) evaluate whether inbreeding is avoided by dispersal and/or mating behavior. Mean pairwise relatedness within packs (R e 0.39) was significantly greater than that estimated from random assignment of individuals to packs. However, breeding pairs were most often unrelated, suggesting that female-biased dispersal reduces inbreeding. We assigned maternity to 49 pups and paternity to 47 pups (n e 12 litters) using a combination of exclusion, likelihood analyses (using CERVUS software), and sibship reconstruction. Multiple paternity occurred in 33% of litters; extrapack paternity accounted for 28% of all resolved paternities, occurring in 50% of litters. We found no evidence that extrapack copulations reduce inbreeding; however, more detailed analyses may elucidate the effect of recent population declines and demographic disturbances due to recurring disease outbreaks. The adaptive advantages of female-biased dispersal and the observed mating system are discussed in relation to Ethiopian wolf sociobiology and ecology. Copyright 2007, Oxford University Press.
How guest experts tell stories about environmental socio-scientific issues in an undergraduate class

ABSTRACT To broaden perspectives presented in undergraduate courses, instructors often invite guest speakers, yet there is limited research on students’ perceptions of guest speakers and the potential influence they may have on student learning. In this exploratory study, we describe how senior undergraduate students, in a natural resource management capstone course, perceived guest speakers, who were invited to lecture on environmental socio-scientific issues. Through qualitative content analysis (guided by frame theory) of student interviews, student artifacts, and transcripts of lectures, we determined that, compared to other speakers, ‘memorable’ speakers (1) told stories, (2) evoked emotion, and (3) either explained theory only after sharing cases studies or intermittently explained theory while sharing a case (rather than beginning with theoretical explanations followed by case studies). Because storytelling was a consistent theme across the ‘memorable’ speakers, we posit that this instructional strategy can be effective in engaging students. We make recommendations for how instructors can select or prepare guests in interacting with undergraduate students.
Mobile Robot Localization Based on Vision and Multisensor

To deal with the low accuracy of positioning for mobile robots when only using visual sensors and an IMU, a method based on tight coupling and nonlinear optimization is proposed to obtain a high-precision visual positioning scheme by combining measured value of the preintegrated inertial measurement unit (IMU) and values of the odometer and characteristic observations. First, the preprocessing part of the observation data includes tracking of the image data and the odometer data, and preintegration of IMU data. Second, the initialization part of the above three sensors includes IMU preintegration, odometer preintegration, and gyroscope bias calculation. It also includes the alignment of speed, gravity, and scale. Finally, a local BA (bundle adjustment) joint optimization and global graph optimization are established, so as to obtain more accurate positioning results.
ANTILISTERIAL POTENTIAL OF IMPERATORIN AND LIMONIN FROM PONCIRUS TRIFOLIATA RAFIN

To discover natural compounds with antilisterial potential, we investigated an ethyl acetate extract of the seeds of Poncirus trifoliata Rafin. , and isolated imperatorin and limonin. The structures were determined on the basis of spectroscopic analysis. The compounds were tested for antibacterial activity against some Listeria monocytogenes strains and found to possess potential antilisterial activity against L. monocytogenes American Type Culture Collection (ATCC 19116, 19111, 19166, 19118 and 15313) with minimum inhibitory concentration (MIC) values ranging from 15.62 to 62.5 µg/mL. The scanning electron microscopic studies also demonstrated that imperatorin and limonin caused morphological changes of L. monocytogenes ATCC 19116 at the MIC value, along with the potential effect on cell viabilities of the tested bacteria. PRACTICAL APPLICATIONS The use of natural compounds of P. trifoliata as antilisterial agents will be suitable for applications on the food industry as natural preservatives or flavoring to control foodborne pathogens. They can be used as growth inhibitors of L. monocytogenes, the most representative foodborne pathogen. The main reason for their suitability is that usually, plant-derived natural compounds are considered as nonphytotoxic and potentially effective against microorganisms. However, they can be toxic or harmful to humans when they are inappropriately used. Caution is generally required if natural compounds are to be taken internally or used on food commodities.
The Utilisation of Prebiotics and Synbiotics in Dogs

The microbiota of the large intestine plays a fundamental role in maintaining the state of health of the gastrointestinal tract and the host. The use of specific dietary supplements such as prebiotics and synbiotics might positively influence the composition and metabolism of the intestinal microbial population. Several studies have been conducted on the use of prebiotics in dogs. Most studies have aimed to assess whether using prebiotics brings about an improvement in the canine intestinal ecosystem. Moreover, the effect of prebiotics on canine immune system has also been investigated. Among the prebiotics used in the studies present in the literature, short-chain fructooligosaccharides and oligofructose seem to be the most effective in modulating the canine intestinal ecosystem and improving intestinal absorption of minerals but with little or no effect on canine immune system. Conversely, mannanoligosaccharides may have a positive influence on the immune system of dogs. Some positive effects of prebiotics on canine intestinal microbiota might be enhanced when these are used in combination with one or more probiotic strains (synbiotic). Clinical effects of prebiotics have been investigated in humans and animal models but little evidence exists that prebiotics may be helpful in canine diseases. Finally, most studies on canine intestinal microbiota were conducted using traditional culture methods, so that more research remains to be done with modern molecular identification methods to investigate the effects of prebiotic substances. This paper presents an overview of the scientific literature dealing with the use of prebiotics and synbiotics in the canine species.
Semiautomated social media analytics for sensing societal impacts due to community disruptions during disasters

Understanding the societal impacts caused by community disruptions (e.g., power outages and road closures), particularly during the response stage, with timeliness and sufficient detail is an underexplored, yet important, consideration. It is critical for effective decision‐making and coordination in disaster response and relief activities as well as post‐disaster virtual reconnaissance activities. This study proposes a semiautomated social media analytics approach for social sensing of Disaster Impacts and Societal Considerations (SocialDISC). This approach addresses two limitations of existing social media analytics approaches: lacking adaptability to the need of different analyzers or different disasters and missing the information related to subjective feelings, emotions, and opinions of the people. SocialDISC labels and clusters social media posts in each disruption category to facilitate scanning by analyzers. Analyzers, in this paper, are persons who acquire social impact information from social media data (e.g., infrastructure management personnel, volunteers, researchers from academia, and some residents impacted by the disaster). Furthermore, SocialDISC enables analyzers to quickly parse topics and emotion signals of each subevent to assess the societal impacts caused by disruption events. To demonstrate the performance of SocialDISC, the authors proposed a case study based on Hurricane Harvey, one of the costliest disasters in U.S. history, and analyzed the disruptions and corresponding societal impacts in different aspects. The analysis result shows that Houstonians suffered greatly from flooded houses, lack of access to food and water, and power outages. SocialDISC can foster an understanding of the relationship between disruptions of infrastructures and societal impacts, expectations of the public when facing disasters, and infrastructure interdependency and cascading failures. SocialDISC's provision of timely information about the societal impacts of people may help disaster response decision‐making.
Standard therapies: solutions for improving therapeutic effects of immune checkpoint inhibitors on colorectal cancer

ABSTRACT Immunotherapy using immune checkpoint inhibitors has opened a new era for cancer management. In colorectal cancer, patients with a phenotype of deficient mismatch repair or high microsatellite instability benefit from immunotherapy. However, the response of rest cases to immunotherapy alone is still poor. Nevertheless, preclinical data have revealed that either ionizing irradiation or chemotherapy can improve the tumoral immune milieu, because these approaches can induce immunogenic cell death among cancer cells. In this regard, combination use of standard therapy plus immunotherapy should be feasible. In this review, we will introduce the specific roles of standard therapies, including radiotherapy, chemotherapy, antiangiogenic and anti-EGFR therapy, in improving therapeutic effect of immune checkpoint inhibitors on colorectal cancer.
THE ECOLOGY OF ARCTIC AND ALPINE PLANTS

‘How are plants adapted to the low temperatures and other stresses of arctic and alpine environments ? ’ At present it is not possible to answer this question completely. Much work remains to be done, particularly on low‐temperature metabolism, frost resistance, and the environmental cues and requirements for flowering, dormancy, regrowth, and germination. However, in brief, we can say that plants are adapted to these severe environments by employing combinations of the following general characteristics:

Feeding rate of freshwater eel Anguilla bicolor bicolor: at the body weight of 1–2 g

ABSTRACT The aim of the research was to determine feed requirement for the maintenance, optimum, and maximum growth of freshwater eel ( Anguilla bicolor bicolor ) seed (1–2 g body weight). Feed used in this research was KRA feed with 46% protein content, with different feeding level (FR) at 0%, 5%, 10%, and 15% of fish biomass. The experiment was conducted in 30 days. Parameters measured were survival and s pecific growth (SGR). The results showed that survival of fish in all treatments were 100%, except in fish fed on 15% of biomass (only 96). Fish growth with feeding of 0%, 5%,10%, and 15%, were -1.06%; 0.42%; 0.73%; and 0.19%, respectively. Based on the analysis of the relationship between feeding level and growth, the feed requirement for maintenance, optimum, and maximum growth in 1–2 g freshwater eel seed were 3.3%; 7.0%; and 9.5% of the biomass, respectively.

Phenological changes in intertidal con‐specific gastropods in response to climate warming

There is substantial evidence from terrestrial and freshwater systems of species responding to climate change through changes in their phenology. In the marine environment, however, there is less evidence. Using historic (1946–1949) and contemporary (2003–2007) data, collected from rocky shores of south‐west Britain, we investigated the affect of recent climate warming on the reproductive phenology of two con‐specific intertidal limpet grazers, with cool/boreal and warm/lusitanian centres of distribution. Reproductive development in the southern limpet, Patella depressa, has advanced, on average, 10.2 days per decade since the 1940s, with a longer reproductive season and more of the population reproductively active. The peak in the proportion of the population in advanced stages of gonad development was positively correlated with sea surface temperature (SST) in late spring/early summer, which has increased between the 1940s and 2000s. The advance in peak reproductive development of this species is double the average observed for terrestrial and freshwater systems and indicates, along with other studies, that marine species may be responding faster to climate warming. In contrast, the northern limpet, Patella vulgata, has experienced a delay in the timing of its reproductive development (on average 3.3 days per decade), as well as an increase in reproductive failure years and a reduction in the proportion of the population reaching advanced gonad stages. These results are the first to demonstrate a delay in the reproductive development of a cool‐temperate, winter spawner, towards cooler more favourable environmental conditions in response to climate warming. Such a delay in spawning will potentially lead to trophic miss‐matches, resulting in a rapid nonlinear decline of this species.
