A Survey on Image Steganography

— Steganography is a branch of science where the secret information can be transmitted in a carrier file, example text, image, audio and video files. Cryptography is a branch of science where secret information is transmitted on the channel by encrypting into coded form. The mere existence of secret information is visible in case of cryptography, where as in the case of steganography, existence of secret information is not visible. Embedding of the secret data in image carrier file is called as an image steganography. Much of the research was carried out in gray scale images to embed data without disturbing the quality of the image. Where as in color image steganography, it is a bit difficult to embed data on color image without disturbing the quality of the image. Hence this paper presents a survey on various methods of steganographic techniques available.
Phyletic evolution and taxonomic characteristics of Bacillus

The traditional classification of Bacillus was done mainly based on the phenotypic characteristics.There were 244 species of Bacillus cited in the book of the"Literature Review on Bacillus"by Liu(2006). With the development of new identification methodologies,especially the polyphasic taxonomical method,changes in the taxonomy of Bacillus are emerging.Many species have been re-classified from the genus into new genera.Based on the second edition of "Bergey′s Manual of Systematic Bacteriology" published in 2004,this paper discusses the evolutional evidence,as well as the characterictics of the typical species of Bacillus related genera.According to the spore-forming,16S rRNA and other characteristics,22 Bacillus related genera have been separated from Bacillus.Of the 22 genera,15 belong to Bacillaceae and 7 are non-Bacillaceae.There are 13 genera that are only Bacillus in name.

Android Platform for Realtime Tracking of the Gait Using Inertial Measurement Units

— This paper presents a system for tracking the gait through the use of Inertial Measurement Units (IMU) which are connected by a bluetooth link to a mobile device running an Android system for data acquisition. It also explains how the system works and the way the data gathering is analyzed. The preliminary measurement was made to test how the system works and to analyze the gait with the identification of its two principal stages and some others sub-stages of it. It shows that the system is a viable tool for the physical therapies to realize the measurement of the gait in a simple, comfortable way and with a low cost. We propose a tool to help physical therapists to evaluate in real time the performance of the gait of people with drop foot and compare with the gait when a drop foot stimulator is used.
Control of leaf abscission in nodal cultures of Annona squamosa L

SummaryAttempts to micropropagate Annona squamosa L. (sugar apple) from nodal expiants have been hindered by complete leaf abscission during establishment in culture. Absorbents and inhibitors of ethylene biosynthesis and action were tested in order to control leaf drop. The inhibitors of ethylene action, silver thiosulphate and 2,5- norbornadiene, were more effective in avoiding leaf abscission than absorbents of ethylene, activated charcoal, mercuric Perchlorate and potassium permanganate, or inhibitors of ethylene biosynthesis, aminoethoxyvinylglycine, aminooxyacetic acid and cobalt chloride. The results suggest that silver compounds can be used as effective inhibitors of leaf abscission in the establishment of Annona squamosa in culture.
Multitasking in Knowledge Intensive Business Services

The objectives of this study were two-fold. First, to analyze multitasking activities in Knowledge Intensive Business Services (KIBS) and the employees’ perception of multitasking effects on individual and organizational performance. Second, to explore associations between the perception of multitasking and individual Time Management Orientation (TMO). The research study employed an online survey methodology. The questionnaire contained 56 questions organised in four groups. Methods of relationship analysis and regression analysis were applied to get answers to the research questions. The study indicated that the employees of surveyed KIBS were strongly engaged in multitasking activities in their workplaces. The informants estimated that on average they worked on nine different tasks per day. Additionally, their working days were filled with interruptions, caused either by external factors or self-interruptions. The majority of respondents also admitted that the ability to multitask was considered their job requirement, thus supporting the findings of other studies that KIBS do prefer multitasking employees. The effects of multitasking on individual and organizational performance were perceived ambiguously by the respondents. Meanwhile, the majority of respondents (above 70%), regardless of the level of polychronicity, admitted that they were able to make good decisions and concentrate better when they worked on one task at a time. The data analysis confirmed the findings reported earlier that individuals with more polychronic TMO did perceive multitasking as having more positive than negative effects both at the individual and organisational levels. Human multitasking has been widely researched in such fields as medicine, command and control, aviation, information technologies, but there is little detailed empirical evidence on multitasking in KIBS such as management consulting, research and development, architecture, engineering services, design, and advertising. Our research provides a fresh view on the human aspects of KIBS companies which can be of help in addressing the related managerial issues. The setting of the optimal number of tasks, task allocation considering employees’ individual differences, designing of workflows require further research as this may give the KIBS company managers guidelines and tools for organizing productive multitasking towards enhanced work efficiency and effectiveness and employees’ well-being.
A scoping review of conventional and laser acupuncture as a modality of treatment for migraine

Introduction: Migraine is a common neurological disorders that typically manifests with repeated episodes of unilateral frequent throbbing headaches. Globally, the prevalence of migraine is around 10%. Despite the wide variety of pharmacological medications, patients still experience frequent attacks or are unable to get complete relief from the prescribed medications. Conventional and laser acupuncture are alternative therapeutic treatment modalities that have been widely used for people with migraine. The purpose of this study was to review the collective evidence on the role of acupuncture in alleviating the symptoms of migraine. Methods: A scoping review of current literature was performed. The inclusion criteria for including interventions in this study were: (a) published in English language between 2013 and January 2018; (b) indexed in MEDLINE/PubMed, CINAHL, AltHealthWatch, and SCOPUS; (c) quantitative evaluations of acupuncture as a modality of treatment; (d) original, peer-reviewed research articles; and (e) utilized patients diagnosed with migraine. Results: A total of 23 interventions with a combined total of 1,714 study participants met the inclusion criteria. Findings indicate that acupuncture is a promising approach in the treatment of migraines accompanied with or without an aura. Limitations of this review included varied dosage of acupuncture among different studies, small sample sizes, and lack of behavioral theory-based approaches in promoting this modality. Discussion and Conclusion: The present evidence indicates that acupuncture may provide symptomatic relief and improvement in quality of life among migraine patients. It has a promising role as an adjuvant to conventional drug therapy. More randomized controlled trials for efficacy and effectiveness testing are needed.

Simulation of Electrical Characteristics of Switching Nanostructures "Pt – TiO – Pt" and "Pt – NiO – Pt" with Memory

The nanostructures “Pt – TiO – Pt” and “Pt – NiO – Pt” with weak switching properties and memory were studied within the framework of semi-empirical Hückel method. The calculation was implemented in the program Atomistix ToolKit with Virtual NanoLab. The transmission spectra, current-voltage characteristics and differential conductivity of nanostructures are calculated. It was revealed that in the range of voltages –1.3 V÷1.3 V, a hysteresis appears in the form of eight shaped figure on the current-voltage characteristic of Pt – TiO – Pt nanostructure, and in Pt – NiO – Pt nanostructure, the hysteresis appears in the voltage intervals –1.8 V÷0.8 V and 0.9 V÷1.8 V in the form of two oval-shaped figures connected to a segment. The manifestation of the hysteresis characteristic of these nanocontacts shows that they have memory. It was found that a negative differential resistance is observed in the voltage range, where the hysteresis of the current-voltage characteristic is appeared. It is shown that the investigating nanostructures have weak switching properties. The results of the paper can be useful for the calculation of memristic elements of nanoelectronics.
Eremiascincus, a new generic name for some Australian sand swimming skinks (Lacertilla: Scincidae)

Work on the systematics of any group of organisms above the species level has generally focused on the genus. Historically, this has been due in large part to the imperative of binomial nomenclature, i.e., every species must be placed in a genus, and, more recently, it has been due to the realization that the genus is an extremely useful biological concept when viewed as a monophyletic group of species showing strong morphological and ecological cohesiveness. A sound systematics at the generic level thus has both great practical and theoretical importance in the study of any group.
IFESS 2016 – La Grande Motte, France

Electrical stimulation is used for example to treat neuronal disorders and depression with deep brain stimulation or transcranial electrical stimulation. Depending on the application, different electrodes are used and thus different electrical characteristics exist, which have to be handled by the stimulator. Without a measuring device the user would have to rely on the stimulator being able to deliver the needed stimulation signal. Therefore, the objective of this paper is to present a method to increase the level of confidence with characterization and modelling of the electrical behavior by using the example of one channel of our stimulation device for experimental use. In several simulation studies with an electrode model with values in a typical range for cortical applications the influence of the load onto the stimulator and the possibility to pre-estimate measuring signals in complex
Quantum-resistant Public-key Authenticated Encryption with Keyword Search for Industrial Internet of Things

—The industrial Internet of Things (IIoT) integrates sensors, instruments, equipment, and industrial applications, enabling traditional industries to automate and intelligently process data. To reduce the cost and demand of required service equipment, IIoT relies on cloud computing to further process and store data. However, the means for ensuring the privacy and conﬁdentiality of the outsourced data and the maintenance of ﬂexibility in the use of these data remain unclear. Public-key authenticated encryption with keyword search (PAEKS) is a variant of public-key encryption with keyword search that not only allows users to search encrypted data by specifying keywords but also prevents insider keyword guessing attacks (IKGAs). However, all current PAEKS schemes are based on the discrete logarithm assumption and are therefore vulnerable to quantum attacks. Additionally, the security of these schemes are only proven under random oracle and are considered insufﬁciently secure. In this study, we ﬁrst introduce a generic PAEKS construction that enjoys the security under IKGAs in the standard model. Based on the framework, we propose a novel instantiation of quantum-resistant PAEKS that is based on NTRU assumption. Compared with its state-of-the-art counterparts, our instantiation is more efﬁcient and secure.
Reliability Improvement of Micro-Inverter through AC-Ripples Voltage Compensator

In this paper the resiliency improvement of micro inverter is considered. Its life degrades mainly due to failure of DC link capacitor. The inherent 100 Hz ripples from inverter stage causes excess heat in capacitor. Consequently, the electrolyte dries out quickly and its lifespan decreases. The objective of this paper is to mitigate such AC harmonics on DC link capacitor. A compensator or active power decoupling circuit, APD, is designed in PSIM. The APD circuit is a combination of film capacitor, H-bridge and control circuit. Second frequency AC ripples are converted into DC by actively controlling the capacitor. In this manner AC harmonics are mitigated at the DC link capacitor. Firstly, a benchmark micro inverter is designed and simulated without using APD circuit. Secondly, active power decoupling is used by designing APD circuit. The simulation results show that there is a decrease in AC ripples from 9.4% to 3.2% by using series voltage compensator as compared to passive power decoupling i.e. only a bulk capacitor. The capacitor life is increased up to 19 years and hence of micro-inverter. The total harmonics distortion (THD) analysis shows that by using active power decoupling, system injects 2.7% THD as compared to passive decoupling which is 1.69%. which is still in bellow the IEEE standard of allowable 5% THD. Keywords— Micro inverter, Reliability, Active Power Decoupling APD, PV system, AC Ripples.
Harnessing the potential to fight from within – immunotherapy advances in cancer treatment

Strategies to treat cancer have largely involved surgical removal of the tumor, broad chemotherapies or radiotherapies that exterminate both tumor and non-tumor cells, and targeted therapies to specifically block functional pathways to eliminate tumor growth. However, despite the type of treatment, cancers often reach a refractory period after prolonged treatment, when the patients fail to respond, leading to disease recurrence. A likely cause for this recurrence is the escape of the tumor cells from immune surveillance, a process that allows the tumors to evade attack by the immune cells and trigger their constant growth. The positive and negative regulators of both innate and adaptive immune cells work in concert through multiple interactions to recognize and eradicate tumor cells. Thus, immunotherapy offers hope in cancer treatment. To this end, biotechnologists together with immunologists are working on challenging medical problems to innovate new therapeutic pathways for cancer therapy. In this editorial, we will discuss recent advances in immunotherapy that are mostly based on countering the pro-tumor properties of the negative regulators of the immune system, to enhance their anti-tumor response.
Magnetic manipulation of lateral migration behavior of a ferrofluid droplet in a plane Poiseuille flow

This study investigates the effect of a uniform magnetic field on the lateral migration behavior of a ferrofluid droplet in a plane Poiseuille flow at arbitrary directions by means of numerical simulation. A numerical scheme called level set method in combination with laminar two phase flow under fluid flow module is used to solve the flow field both inside and outside of the droplet, while level set method is required to track the dynamic motion of the droplet interface which is suspended in another immiscible medium. A parabolic flow is generated by means of a pressure gradient. Magnetic field both inside and outside of the droplet is simulated using the AC/DC module, and it is coupled to the flow domain using the volume force feature under laminar flow module. We found that at a low droplet Reynolds number (Red ≤ 0.05), the magnetic field direction can effectively manipulate the final equilibrium position of the droplet along a channel. Keeping the viscosity ratio fixed (i.e., λ = 1), at α = 0, the droplet finds its equilibrium position closer to the bottom wall, while at α = 45and 90 the droplet settles closer towards the channel center. Also, at a steady state the droplet is found to align itself towards the direction of the magnetic field.
The Effect of Relative Humidity on Pollen Vigor and Fruit Setting Rate of Greenhouse Tomato under High Temperature Condition

In order to study the effects of different air humidity on the pollen vigor of tomato under high temperature,the experiments using two tomato varieties were carried out in a growth chamber(150 cm×120 cm×200 cm)with nature light.During the period of 10:00-16:00 each day,tomato plants were treated with relative humidity of 85%-90%(H),65%-70%(M) and 35%-40%(L,non-humidification as control) at temperature 32-35 ℃. From the observation of 2nd to 4th truss of tomato plants,the results showed that: compared with treatment L,the pollen number,pollen vigor and pollen germinating rate in treatment H were increased by 53%-135%,64%-166% and 77%-132%,respectively.The fruit set rate,for the average,increased by 34%-77%. The treatment M also showed some positive effect.The performance of two varieties was the same.In addition,with the time continuing of high temperature and the consumption of nutrition,the pollen number,pollen vigor and pollen germinating rate of the 4th truss were 48%-89%,53%-96% and 72%-97% that of 2nd truss,respectively.
Functional analysis of DA1-Related Protein 2 in Arabidopsis under salt stress: Functional analysis of DA1-Related Protein 2 in Arabidopsis under salt stress

Salt stress inhibits plant growth and development, resulting in low crop yield. Therefore, the mechanism of plant response to salt stress has received much attention in plant science research. Early development (including seed germination and greening) is not only critical for seedling establishment and subsequent plant growth and development, but is also more sensitive to salt stress. However, the molecular mechanisms underlying plant salt tolerance during this developmental stage has remained largely unknown. In this study, we identified a gene, DAR2 (DA1-Related Protein 2), which regulated primary root growth by map-based cloning in Arabidopsis. We noted that DAR2 gene was induced by 200 mmol·L NaCl in 10-day-old Col-0 seedlings. GUS staining showed that the expression of pDAR2::GUS was altered, suggesting that DAR2 gene was induced in root tip and leaf apex phloem. We counted the Col-0 and dar2-3 seed germination and greening rates in different MS medium — 0 (CK), 100 mmol·L NaCl, 150 mmol·L NaCl, 200 mmol·L NaCl, 150 mmol·L KCl and 200 mmol·L mannitol. These results showed that compared with the wild type, either seed germination or greening of dar2-3 mutant obviously delayed with gradual increase in NaCl concentration. Under 150 mmol·L KCl and 200 mmol·L mannitol treatments, dar2-3 mutant seed germination and greening delayed in relation to the wild type. Interestingly, the mutant exhibited increased sensitivity to NaCl, KCl and mannitol treatments during seed germination and greening compared with the wild type. These results suggested that while DAR2 was effective in mediating plant response to general osmotic stress, it was not specific to ion stress in the early growth and development phase. Our findings provided novel 64 中国生态农业学报 2014 第 22卷 insights into salt tolerance and enhanced crop resistance to salt stress.
ESTIMATES OF MEAN POPULATION DENSITY AND SPATIAL DISTRIBUTION OF TETRANYCHUS URTICAE (ACARINA: TETRANYCHIDAE) AND PHYTOSEIULUS PERSIMILIS (ACARINA: PHYTOSEIIDAE) BASED UPON THE PROPORTION OF EMPTY SAMPLING UNITS

SUMMARY (1) A simple but general model of density dependent dispersal in an arthropod population is used to explain the relationship between the density and the spatial distribution of two species of mites: the two-spotted spider mite, Tetranychus urticae, and its phytoseiid enemy Phytoseiulus persimilis, used for biological control of spider mites in glasshouses. (2) Based on the above relationship, estimates of mean mite densities in glasshouses are obtained from sampling data in which only presence or absence of individuals has been recorded. (3) Confidence limits for the true mean density estimated from the proportion of sampling units without individuals (the zero-group) are provided for the two mite species. Estimates of variances require that Taylor's power law is a suitable model of the variance/mean relationship. (4) Reliability of density estimates obtained by the zero group method is compared with that based on direct counts of individuals occurring in a sample. Although counting provides the most precise estimates for a given sample size, the former method is both easier and faster to apply than counting. This makes the zero-group method advantageous to use at high population densities where counting becomes very tedious. (5) The overall spatial distribution of spider mites is predicted from an observed proportion of empty sampling units. This presupposes, however, that the negative binomial is a general model of the underlying spatial distribution of the species but not that the parameter k of the negative binomial is independent of the population density.
