Repot: Real‐time and privacy‐preserving online task assignment for mobile crowdsensing

Recently, the development of Internet of Things and mobile sensor technology has facilitated mobile crowdsensing (MCS) as a popular data collection paradigm. In MCS, requesters publish tasks to the sensing platform, and then the sensing platform assigns tasks to workers who carry mobile sensing devices. In general, the sensing platform matches tasks and workers according to the location and time attributes of tasks and workers. However, most current studies rarely consider location and time attributes, simultaneously. In previous work, it is difficult to achieve real‐time task assignment while protecting worker's location privacy. To tackle the above problem, in this article, we propose a real‐time and privacy‐preserving online task assignment scheme, named Repot. In Repot, the location privacy of workers is protected by using geoindistinguishability. And we design a probabilistic method to quantify the reachability between the obfuscated worker and the task. In addition, the worker‐based distance comparison mechanism and the task‐based distance comparison mechanism are designed to reduce the overall distance of workers in Repot, respectively. The experimental evaluation is performed on a real‐world data set and the results show the feasibility and effectiveness of Repot.
Conversational Implicature Analysis in “Kingdom of Heaven” Movie Script by William Monahan

This study was designed to discover the types of conversational implicature and the non-observance maxim of cooperative principles expressed by the characters in the Kingdom of Heaven movie script by William Monahan. The theory of Grice was applied to analyze the conversational implicature, and the qualitative approach is used to explain the conversational implicatures. After analyzing the movie, we discovered particularized implicatures as the most frequent conversational implicatures in the movie script with 14 occurrences, followed by six occurrences of generalized implicatures. The finding also revealed that the frequent use of flouting maxim of quantity occurred more frequent with 14 out of the total 20 excerpts, with violating maxim found only three times in the movie script. From this study, both findings suggested the reason behind the frequent use of flouting maxim compare to violating maxim in conversational implicature is because the speaker assumes that they will be in a safe position, and then expect the hearer to understand their points, as the speaker did not intentionally manipulate or mislead the hearer.
Fatigue detection based on multi-feature fusion of fatigue behavior

The research of fatigue driving detection is of great significance due to the contribution in fatigue driving prevention. However, most of current fatigue detection study are limited to unavailable real-time performance, unsatisfied accuracy rate, rough fatigue level and complicated implementation. In this paper, a novel method based on multi fatigue behavior features are proposed to improve the accuracy of fatigue detection. First of all, multi facial behavior features including eyes, mouth and head features are extracted. And then a new multi-feature fusion fatigue detection approach based on specific fatigue behavior feature anaylsis is proposed to recognize the previously extracted features. For better accuracy and applicability, a more detailed fatigue levels are newly used to subdivide fatigue behavior into three degree of fatigue. The experimental results based Matlab simulation and Android App indicate that the proposed method could accurately and real-time detect whether the tester is in a state of fatigue driving, and also determine the fatigue level.
Antibiotic Resistance of Symbiotic Marine Bacteria Isolated from Marine Organisms in Jeju Island of South Korea

We investigated antibiotics resistance of bacteria isolated from marine organisms in Jeju Island of South Korea. We isolated 17 strains from a marine sponge, algaes, and sea water collected from Biyangdo on Jeju Island. Seventeen strains were analyzed by 16S rRNA gene sequencing for species identification and tested antibiotic susceptibility of strains against six antibiotics. Strain JJS3-4 isolated from S. siliquastrum showed 98% similarity to the 16S rRNA gene of Formosa spongicola A2T and was resistant to six antibiotics. Strains JJS1-1, JJS1-5, JJS2-3, identified as Pseudovibrio spp. , and Stappia sp. JJS5-1, were susceptive to chloramphenicol and these four strains belonged to the order Rhodobacterales in the class Alphaproteobacteria. Halomonas anticariensis JJS2-1, JJS2-2 and JJS3-2 and Pseudomonas rhodesiae JJS4-1 and JJS4-2 showed similar resistance pattern against six antibiotics. We could isolate bacteria from marine organisms and their antibiotic resistance investigated, and conducted this study under the premise that such bacteria could produce secondary metabolites that could bring about useful antibiotic effects, resulting in species-specific results. We have a lot of unknown marine resources that we have not been able to explore yet. Bacteria are a valuable resource that can be developed into new useful materials.
Isothermal decomposition kinetics and possible decomposition process of pentaerythritol tetranitrate

ABSTRACT The isothermal decomposition kinetics of pentaerythritol tetranitrate (PETN) was studied through a self-established isothermal thermal decomposition gas metering device. The pressure versus time curves of the gas generated by PETN decomposition under different temperature conditions were divided into two parts, showing the remarkable effect of temperature and melting point on PETN decomposition. Model-fitting calculation result showed that the decomposition of PETN at 90–110°C conformed to the No. 8 model, namely, the anti-Jander equation, and a corresponding activation energy Ea of 107.1 kJ·mol−1 with ln(A/s−1) = 6.97. Within a temperature range of 112–130°C, the decomposition model of PETN conformed to the No. 28 model with reaction order n = 4. The device was simultaneously used to predict the time of PETN to reach a certain decomposition extent. Results showed that the time of PETN was extrapolated to 54.4 years when the extent of reaction reached 0.1% at ambient temperature (25°C). Furthermore, Fourier transform infrared spectroscopy and scanning electron microscopy were used to characterize PETN decomposition residues with different decomposition depths to understand the decomposition process.
Listeria monocytogenes in Medical Research

Bacteria are known to produce compounds of high value such as secondary metabolites used in biotechnological applications. It is therefore worthwhile to think how to exploit a pathogenic bacterium, e.g., Listeria monocytogenes , to be an effective source of bioactive compound used in particular in medicinal purposes. Listeria monocytogenes is considered as an acute contaminated bacterium in foods and could be a causal agent of food-borne diseases. This bacterium is the causal agent of listeriosis, a grave disease, caused by eating contaminated food. Although, L. monocytogenes is a pathogenic microorganism that threatens the progress of food industry, it would be also a reservoir of secondary metabo- lites such as antibiotics and other metabolites of economic importance when appropriate strain improvement will be addressed. This section would discuss in brief the negative and positive features of L. monocytogenes as either a pathogenic bacterium or an important microorganism in medical research.
Determining the Role of Saly in Streptococcus Pyogenes Immune Evasion Using Fluorescence Microscopy

Streptococcus pyogenes, the etiologic agent for several life-threatening invasive diseases, utilizes numerous mechanisms to evade the host immune response and establish a successful infection causing a significant source of morbidity and mortality risks for patients. The bacterium is known to cause necrotizing fasciitis in both humans and zebrafish, with extensive necrotic damage to tissues but surprisingly lacking in an inflammatory response for a systemic infection. This suggests that the recruitment of inflammatory cells to the site of infection is inhibited. To observe this in real-time, we used the zebrafish model of Streptococcal pathogenesis to analyze immune cell recruitment in the attenuated putative ABC transporter permease mutant, SalY, and lantibiotic mutant, SalA, to explain the difference in virulence as compared to wild-type. Fluorescence microscopy using transgenic zebrafish with fluorescent immune cells reveals increased colocalization with macrophages in larvae infected with SalY mutant and a two-fold increase in the number of macrophages recruited early on to the site of infection compared to wild type. Bacterial recovery of SalY-mutant infection significantly decreased by nearly 85% compared to wild type. SalA mutant exhibited comparable observations to SalY mutant in immune cell recruitment and bacterial recovery. Further characterization of conserved genes of the Salivaricin locus in relation to their function in immunity will provide insight into a new mechanism for immune evasion and potentially lead to the development of novel antimicrobials to help address the significant healthcare burden posed by this pathogen.
Stability of Resistance to Imidacloprid in the Brown Planthopper (Nilaparvata lugens Stål.) from Banyumas, Central Java

Imidacloprid is one of the insecticides that has been widely used to control the brown planthopper ( Nilaparvata lugens Stal.). The excessive use of insecticides led to the development of insecticide resistance in N. lugens . This study was aimed to determine the stability of resistance to imidacloprid in N. lugens from Banyumas, Central Java Province. The five generations of selection increased the resistance ratio (RR) from 46.20-fold to 150.39-fold. To assess the stability of resistance to imidacloprid in N. lugens , the fifth generation was further reared for 10 generations without exposure to insecticides. The stability studies showed that resistance to imidacloprid was unstable with a decrease of resistance from 150.39-fold to 38.14-fold after 10 generations without selections. Continuous selections with imidacloprid for three generations could increase the resistance level from 150.39-fold to 216.13-fold. The unstable resistance could be managed by removing the selection pressure for a period of time or switching to insecticides with different mode of actions. Information regarding resistance stability would be useful to determine an effective resistance management strategies in N. lugens . v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} . shape {behavior:url(#default#VML);} Normal 0 false false false IN X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:. 0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}
Detecting Lower Back Pain Using Stacked Ensemble Approach

Lower Back Pain (LBP) is a disease that needs immediate attention. Person with back pain shall go immediately to doctor for treatment. Injury, excessive works and some medical conditions are result of back pain. Back pain is common to any age of human for different reasons. Due to factors such as previous occupation and degenerative disk disease the chance of developing lower back pain increases for older people. It hampers the working condition of people common reason for seeking medical treatment. The result is absence from work and is unable to normal due to pain. It creates uncomfortable and debilitating situations. Hence, detecting this disease at an early stage will assist the medical field experts to suggest counter measures to the patients. Detection of lower back pain is implemented in this paper by applying ensemble machine learning technique. This paper proposes Stacking ensemble classifier as an automated tool that will predict lower back pain tendency of a patient. Experimental result implies that the proposed method reaches an accuracy of 76.34%, f1-score of 0.76 and MSE of 0.34.
Phosphatidylinositol 3,5-Bisphosphate Regulates Yeast Vacuole Fusion at the Transition between trans-SNARE Complex Formation and Hemifusion

Phosphoinositides (PIs) regulate myriad cellular functions including membrane fusion, as exemplified by the yeast vacuole, which uses various PIs at different stages of fusion. In light of this, the effect of phos-phatidylinositol 3,5-bisphosphate [PI(3,5)P2] on vacuole fusion remains unknown. PI(3,5)P2 is made by the PI3P 5-kinase Fab1/PIKfyve and has been characterized as a regulator of vacuole fission during hyperosmotic shock where it interacts with the TRP family Ca2+ channel Yvc1. Here we demonstrate that exogenously added dioctanoyl (C8) PI(3,5)P2 abolishes homotypic vacuole fusion. This effect was not linked to interactions with Yvc1, as fusion was equally affected using yvc1Δ vacuoles. Thus, the effects of C8-PI(3,5)P2 on fusion versus fission operate through distinct mechanisms. Further testing showed that C8-PI(3,5)P2 inhibited vacuole fusion after the formation of trans-SNARE pairs. Although SNARE complex formation was unaffected we found that C8-PI(3,5)P2 strongly inhibited hemifusion. Overproduction of endogenous PI(3,5)P2 by the fab1T2250A hyperactive kinase mutant also inhibited at the hemifusion stage, bolstering the model in which PI(3,5)P2 inhibits fusion when present elevated levels. Taken together, this work identifies a novel function for PI(3,5)P2 as a negative regulator of vacuolar fusion. Moreover, it suggests that this lipid acts as a molecular switch between fission and fusion.
The extracts of Angelica sinensis
 inhibit lipid oxidation in fish erythrocytes and improve growth, digestive, absorptive and antioxidant capacity in juvenile Jian carp (Cyprinus carpio 
var. Jian)

The study explored the effects of ethyl ether extract, ethyl acetate extract (EAE), acetone extract, ethanol extract and aqueous extract of Angelica sinensis (EAs) and ethoxyquin (EQ) on lipid oxidation in erythrocytes and growth, digestive, absorptive and antioxidant capacity in carp (Cyprinus carpio var. Jian). The results indicated that EAs and EQ respectively at the concentrations of 0.5 and 0.25 mg/ml suppressed lipid oxidation by decreasing the generation of ROS and restoring the activities of antioxidants in hydroxyl radical‐treated erythrocytes. Of all of the examined EAs, EAE showed the strongest protective effects against lipid oxidation in carp erythrocytes. The antioxidant effects of EQ at the concentration of 0.25 mg/ml were stronger than that of EAE at the concentration of 0.5 mg/ml in fish erythrocytes. The antioxidative activities of EAs in carp erythrocytes were positively correlated with their phenols content. Moreover, dietary EAE raised growth performance in fish. The appropriate concentration of EAE for the growth of fish was estimated to be 3.544 g/kg diet. Dietary EAE increased digestive and absorptive capacity in carp and improved antioxidant capacity in copper‐treated carp. So, EAE could be used as a potential natural antioxidant and inhibitor of copper stress in fish.
Changes in Assemblages and Diversity Patterns of Carabidae (Coleoptera) from 1997 to 2014 in a Desalinized, Intensively Cultivated Agricultural Landscape in Northern China

Abstract Reclamation of salinity-affected land for intensive agricultural production represents a highly promising pathway towards feeding our increasing global population. Nonetheless, biodiversity and ecosystem service responses to agricultural intensification in desalinized landscapes remain poorly understood. In our study, we analyzed long-term diversity responses of carabids as important pest control agents to agricultural intensification in desalinized landscapes by comparing data from 1997 and 2014, and we analyzed the potential role of field-margins as beetle refuge habitats. Despite agricultural intensification, carabid species richness increased significantly following desalinization, with this increase being chiefly limited to field margins. Carabid assemblages also showed a dramatic temporal species turnover, leading towards a species-rich, homogeneous community dominated by generalists. Therefore, we believe that desalinization triggered positive regional diversity responses despite simultaneous agricultural intensification, with semi-natural field margins playing an increasingly important role as local diversity hotspots. Nonetheless, the highly uniform composition of the generalist beetle assemblages and its potential implications for ecosystem functioning require further scrutiny, and the targeted management of semi-natural habitats appears crucial to optimize farmland biodiversity and associated ecosystem services in desalinized agricultural landscapes.
Finite element analysis (FEA) of frictional contact phenomenon on vehicle braking system

Abstract The braking phenomenon is an aspect of vehicle stopping performance where with kinetic energy due to the speed of the vehicle is transformed into thermal energy via the friction between the brake disk and its pads. The heat must then be dissipated into the surrounding structure and the airflow around the brake system. The frictional thermal field during the braking phase between the disk and the brake pads can lead to excessive temperatures. In our work, we presented numerical modeling using ANSYS software adapted in the finite element method, to follow the evolution of the global temperatures for the two types of brake disks, full and ventilated disk during braking scenario. Also, numerical simulation of the transient thermal and the static structural analysis were performed here sequentially, with coupled thermo-structural method. Numerical procedure of calculation relies on important steps such that the computational fluid dynamic (CFD) and thermal analysis have been well illustrated in 3D, showing the effects of heat distribution over the brake disk. This CFD approach helped in the calculation of the values of the heat transfer coefficients (h) that have been exploited in the 3D transient evolution of the brake disk temperatures. Three different brake disk materials were tested and comparative analysis of the results was conducted in order to derive the one with the best thermal behavior. The current numerical results were in good agreement with the previous experimental results available in literature. Finally, the resolution of the coupled thermomechanical model allows us to visualize other important results of this research, such as; the deformations, and the equivalent Von Mises stresses of the disk, as well as the contact pressure distribution on the brake pads. According to the results presented in this investigation, several conclusions can be drawn. The choice allowed us to deliver the excellent rotor design to ensure and guarantee the better braking performance of the vehicles.
Hermeneutics and Phenomenology in Human and Social Sciences Research

This article of reflection problematizes the relationships between phenomenology and hermeneutics as epistemic places of research work through a documentary approach built in two phases. First, the text reflects on the terminological use present in the paradigms, approaches, epistemological perspectives, and research methods, thereby identifying that there is no criteria univocity in its references and approaches about research methodology treaties. Likewise, it is evident that there are methodological proposals that include phenomenology and hermeneutics in a complementary, articulated, or isolated way without allowing precise places of understanding that allow to locate their application in research. Based on the aforementioned, the second phase proposes an individual approach to the background and comprehensions of phenomenology and hermeneutics, identifying particularities that characterize them, possible theoretical-practical differences and approaches that can be established in view of their relevance from the epistemic and methodological framework of research in human and social sciences.
An Economic Analysis of Efficiency and Equality Combining Epistemological True with Axiological Good Through Microeconomics to Macroeconomics

Applying the Arrow-Debreu-Mundell-Fleming model as an economic standard model, with combining axiological framework and epistemological model, it is proposed to analyze economic policies with using a synthetic model, where interest, exchange and tax rates are integrated together. Except normal monetary and fiscal policies mainly via interest and tax rates, there are feasible ways to utilize modified strategies via exchange and tax rates. When ones need to simulate national local market, ones can raise the exchange rate. Otherwise, when ones need to promote international global trade, ones may lower the exchange rate. It is found that tax reduction is good policy when tax rate is higher than normal and that tax increase is good social policy when tax rate is lower than normal, during economic depression. Also it is revealed that tax reduction is good social policy when tax rate is lower than normal, and that tax increase is good policy when tax rate is higher than normal, during economic overheat. While economic system seeks efficiency and social system pursues equality, common interest modifications with elastic exchange and tax rates could be applied for balancing efficiency and equality.
Tracing the Distribution of Chinese and World Bank-Funded Projects and Public Demonstrations in Cameroon and Uganda

Extant literature has explored the effects of foreign aid on armed conflicts and state repression, but not on public demonstrations. This article compares distribution patterns of Chinese and World Bank-funded projects and public demonstrations in Cameroon, receiving predominantly Chinese official finance, and Uganda, receiving predominantly traditional, Western aid. Distributive patterns suggest negative and positive associations between Chinese and traditional official finance on the one hand and public demonstrations on the other. However, with respect to anti-project demonstrations specifically, I find through fieldwork interviews in Cameroon that Chinese-funded projects are more prone to anti-project demonstrations owing to less stringent risk management standards.
