The Classical Limit Of Quantum Gravity

We elaborate on the idea of fake particle and study its physical consequences. When a theory contains fakeons, the true classical limit is determined by the quantization and a subsequent process of “classicization”. One of the major predictions due to the fake particles is the violation of microcausality, which survives the classical limit. This fact gives hope to detect the violation experimentally. A fakeon of spin 2, together with a scalar field, is able to make quantum gravity renormalizable while preserving unitarity. We claim that the theory of quantum gravity emerging from this construction is the right one. By means of the classicization, we work out the corrections to the field equations of general relativity. We show that the finalized equations have, in simple terms, the form 〈F 〉 = ma, where 〈F 〉 is an average that includes a little bit of “future”.
PHASE-LOCKED LOOP APPLICATION TO FREQUENCY MODULATION-ATOMIC FORCE MICROSCOPE

The Atomic Force Microscope introduced the surface investigation with true atomic resolution. In the dynamic mode of operation both amplitude and frequencymodulation methods can be implemented by using Phase-Locked Loops. Here it is shown that Phase-Locked Loops can improve the perfomance of the Atomic Force Microscope providing the feedback signal to control both the amplitude and the oscillation frequency of the cantilever. It is also presented a method to design stable third-order Phase-Locked Loops.
Is Tacit Knowledge Really Tacit ?

The aim of this article is to increase understanding of tacit knowledge as a phenomenon and also, to specify and understand tacit knowledge of an expert in a given context. In the discourse of organizational behavior, the use of the concept of tacit knowledge and empirical scientific research on it has become more popular only in the 1990s. The strong increase in expert work and knowledge-intensive fields make examining the topic timely and both theoretically and practically interesting. The most significant theoretical contribution of the study is the increase in understanding, as well as, the creation of new knowledge of the contents and the nature of tacit knowledge. Based on our study, it seems that the current division of knowledge to explicit and tacit is not sufficient to describe the phenomenon. It has been proposed that explicit knowledge is visible and “articulated” knowledge that can easily be transferred and codified, e.g., through speech, documents and various information management systems. Implicit knowledge, on the other hand, is “silent”, hidden and non-verbal knowledge that is difficult or even impossible to transfer and express verbally. We propose that tacit knowledge comprises different components, some of which can be articulated and made explicit. Examples of such are individual‟s or organizations accustomed lines of action that are based on explicit instructions. On the other hand, individual-specific tacit knowledge that includes feelings, emotions and intuition, individual‟s intuitive behaviour or personal relationships, can be considered as “the genuine tacit knowledge” in the sense that it cannot be made visible or transferred. These findings suggest that the interconnectedness of explicit and tacit knowledge ought to be examined further.
Partial Characterization of Cold Active Alkhophilic Protease from Kashmir

Cold active alkaline proteases from microbial sources are of great importance due to their activity and stability in cold conditions and at alkaline pH. They can be used in diverse industrial applications as in detergents, textiles, baking, brewing, starch, animal food, leather and the pulp industries, including agricultural, chemical, and pharmaceutical applications. In present study 28 bacterial isolates were isolated from the soil sample of Kashmir region and screened for protease activity on skim milk agar and casein agar medium under cold (0-10oC) and alkaline (pH 9-14) conditions. Among all the isolates showing protease activity, MLP1 isolate was further characterized. The enzyme produced by MLP1 was stable in the alkaline pH range of 9.0-14.0 with the pH 8.0 and optimum temperature at 8oC. The protease showed highest thermal stability at 6 oC. Future studies involve the cloning of gene encoding alkaline protease that can be used as a substitute to toxic chemicals used in leather industry and mostly in detergents. The ability to work at low temperature and high alkophilic conditions of this enzyme could make it valuable candidate in the field of enzyme
Estimating and Visualizing the position range of a BLE tag

When we lost something or search for things that are hidden in many similar things, such as a bicycle in the parking lot, it is necessary to know the position information of those things. In order to know the position information of the search target, there are some research works to detect an object by attaching a small size ID tag to the target in advance and using indoor-positioning technology to estimate the position of that ID tag. However, because of the narrow range of the ID tag’s signal, if the seeker is far away, the radio wave cannot reach the seeker device and it becomes impossible to retrieve the position information of the target. We propose a method for estimating the position range of a BLE tag using the devices brought by others who pass by the area of the target object with which a BLE tag is attached. The estimated position range is also visualized as a heat map to support seeking an object. This method enables a seeker to find a lost object at a distant place from that object’s location.
A PRIORI ERROR ANALYSIS OF THE LOCAL DISCONTINUOUS GALERKIN METHOD FOR THE VISCOUS BURGERS-POISSON SYSTEM

In this paper, we propose and analyze the local discontinuous Galerkin method for the viscous Burgers-Poisson system. The proposed method preserves two invariants and hence, yields solutions even for long time. A priori error estimates, which are of order O(h), when polynomials of degree k ≥ 1 are used for approximating solutions are established. Finally, numerical experiments are conducted to confirm our theoretical results.

Wealth Inequality , Innovative Talent , and Occupational Choices

Does inequality hinder or foster innovation? We study an occupational choice model in which agents differ in observable wealth and unobservable innovative talent. Investors deposit their wealth in banks, whereas entrepreneurs set up risky firms and can privately choose the novelty of the technology used and the effort exerted. Since financial contracts can be made contingent only on wealth, wealth classes form endogenously and, in general equilibrium, the interest rate adjusts to clear the credit market. In a quantitative illustration, we show that increased inequality can lead to a decrease in both the average quality of the innovators and the number of successful innovations, and to an increase in the number of non-innovative entrepreneurs; this effect, however, depends on the original wealth distribution and the aggregate wealth level.
Assessment of Gender Differences on Aggressive Behaviour among Undergraduates of Benue State University Makurdi , Nigeria

An assessment into the influence of gender difference on aggressive behaviour among undergraduates of Benue State University, Makurdi, was conducted in a survey of 150 participants drawn from undergraduates of Benue State University. The participants made up of 73 (48.7%) males, 77 (51.3%) females took part in the study. An adjusted five-point Likert scale questionnaire was used for data collection. The findings showed there is a statistical significant difference between male and female on physical aggression among undergraduates of Benue State University. (F, df = : 148) = 13.330; p < 0.05). The findings also showed that there is a statistical significant relationship between gender difference and verbal aggression among undergraduates of Benue State University. (r,df=:148)=. 041;p<0.05). There is no statistical significant relationship between gender difference and anger among undergraduates of Benue State University. (r, df = : 148) = . 885; p > 0.05). These findings were discussed within the frame work of gender difference and aggressive behaviour. Finally recommendations were made among which Students involve in aggression cases should in addition to other measures be referred to the school counsellor for remediation.
Ethnographic insights into safety communication for frontline workers

Recent calls for organisation studies to embrace ‘the practice turn’ (Whittington, 2011) have expanded into an understanding of the potential for ethnographic research in occupational health and safety (OHS) research (Pink et al., 2016). The ethnographic project described here, with fieldwork conducted between 2008 and 2010, is one element of this growing appreciation of the potential for qualitative research in industrial settings. Ethnographies have not often been used in OHS settings, and ‘much practicebased knowledge remains undocumented, informal, unspoken and thus unaccounted for’ (Pink et al., 2016, p. 27). This study was motivated by an aim to make explicit the tacit safety knowledge understood and practised by a public service workforce subject to high injury rates. The research team, with Teague as field-based ethnographer, undertook a detailed investigation with customer-facing, frontline staff in a transport organisation. The article uses Teague’s ethnography to argue that new insights into improved safety practices are accessible via investigation of the everyday challenges and responses practised by frontline staff. It demonstrates the value of ethnographic research in opening up new avenues for understandings that can inform OHS policy development and the implementation of OHS procedures within complex organisations. In the context of this particular frontline customer service workforce, staff are positioned in an us-and-them relationship to members of the public through being required to work in pairs. The safety culture relies heavily upon partners looking out for each other, which can create social and emotional distance from the members of the public they are employed to serve. At the same time, the role appeals to people who have experience in security-based shiftwork, including former defence force personnel, firefighters and police. The physical fitness requirements of the role, and reliance on teamwork, complicate the communicative context when engaging with members of the public. This is particularly so when customers are verbally aggressive and/or impacted by
Hybrid heterostructures and heterostructure devices fabricated by surface activated bonding technologies

Surface activated bonding (SAB) is successfully applied for fabricating hybrid heterostructures, which are made of semiconductors with different lattice constants, coefficients of thermal expansion, and crystal symmetries, such as GaAs/Si and 4H-SiC/Si systems. We find that their electrical properties are improved by a post-bonding annealing. Performances of hybrid InGaP/GaAs/Si triple-junction cells and the possibility of Si/SiC Schottky diodes are examined. SAB of diamond to Si is also discussed.
On-Load Tap-Changers for Power Transformers

On-load tap-changers (OLTCs) are indispensable in regulating power transformers used in electrical energy networks and industrial applications. This paper explains the technological developments of resistor-type OLTCs and reactor-type OLTCs. The general switching principles for OLTCs are discussed and OLTC applications are presented. Today’s OLTC design concepts, including the new generation of vacuum type OLTCs, are described. The vacuum switching technology used in OLTCs is the “state of the art” design now and in the foreseeable future. Examples of OLTC designs and the respective switching principles show the range of the usage of vacuum interrupters

Molecular characterization of LhpR in control of hydroxyproline catabolism and transport in Pseudomonas aeruginosa PAO 1

Utilization of hydroxy-L-proline (L-Hyp) in Pseudomonas aeruginosa requires conversion of L-Hyp to D-Hyp followed by the D-Hyp dehydrogenase pathway; however, the molecular mechanism in control of L-Hyp catabolism and transport was not clear. DNA microarray analysis revealed twelve genes in two adjacent loci that were induced by exogenous L-Hyp and D-Hyp. The first locus includes lhpABFE encoding a Hyp epimerase (LhpA) and D-Hyp dehydrogenase (LhpBEF), while the second locus codes for a putative ABC transporter (LhpPMNO), a protein of unknown function (LhpH), Hyp/Pro racemase (LhpK) and two enzymes in L-Hyp catabolism (LhpC and LhpG). Proximal to these two loci, lhpR encodes a transcriptional regulator of the AraC family. The importance of these genes on L-Hyp catabolism was supported by growth phenotype analysis on knockout mutants. Induction of the lhpA and lhpP promoters by exogenous L-Hyp and D-Hyp was demonstrated by the measurement of b-galactosidase activities from promoter-lacZ fusions in PAO1, and no induction could be detected in the DlhpR mutant. Induction of the lhpA promoter by D-Hyp was completely abolished in the lhpA lhpK double mutant devoid of two epimerases, while the induction effect of L-Hyp remained unchanged. The purified His-tagged LhpR binds specifically to the lhp promoter regions, and formation of nucleoprotein complexes is affected by the presence of L-Hyp but not D-Hyp. Putative LhpR binding sites were deduced from serial deletions and comparative genomic sequence analysis. In summary, expression of lhp genes for Hyp catabolism and uptake requires the transcriptional activator LhpR and L-Hyp as the signalling compound.
The effect of metal transfer modes and shielding gas composition on the emission of ultrafine particles in MAG steel welding

The present study aims to characterize ultrafine particles emitted during gas metal arc welding of mild steel and stainless steel, using different shielding gas mixtures, and to evaluate the effect of metal transfer modes, controlled by both processing parameters and shielding gas composition, on the quantity and morphology of the ultrafine particles. It was found that the amount of emitted ultrafine particles (measured by particle number and alveolar deposited surface area) are clearly dependent from the main welding parameters, namely the current intensity and the heat input of the welding process. The emission of airborne ultrafine particles increases with the current intensity as fume formation rate does. When comparing the shielding gas mixtures, higher emissions were observed for more oxidizing mixtures, that is, with higher CO2content, which means that these mixtures originate higher concentrations of ultrafine particles (as measured by number of particles by cubic centimeter of air) and higher values of alveolar deposited surface area of particles, thus resulting in a more hazardous condition regarding welders exposure.
General methods for the subjective assessment of sound quality

The ITU Radiocommunication Assembly, considering a) that the introduction of new kinds of sound signal processing, such as digital coding and bit rate reduction, new kinds of television signals using time multiplexed components and new services such as enhanced television and high definition television (HDTV), may require new or amended methods of subjective sound quality assessment; b) that these techniques entail their own specific signal impairments; c) that subjective listening tests permit assessment of the degree of annoyance caused to the listener by any impairment of the wanted signal during its transmission between the source and the listener; d) that many different methods of subjective testing are possible; e) that it is highly desirable to standardise the methods of subjective testing and the interpretation of the results, so that the best possible comparisons may be made between results obtained at different times and/or in different places; f) that it is highly desirable that the grading scales which are used to describe the subjective quality of sound should permit more consistent statistical processing methods, independent from the language used to express the opinions; g) that it would be desirable for a single assessment scale to be available for both sound and television programmes; h) that the geometric and acoustic properties of control rooms and listening rooms can have a considerable influence on audition, and therefore listening conditions should be closely specified, recommends 1 that the testing and evaluation procedures given in Annex 1 to this Recommendation should be used for the subjective assessment of the quality of reproduced sound. * Radiocommunication Study Group 6 made editorial amendments to this Recommendation in 2002 in accordance with Resolution ITU-R 44.
Combined effect of temperature and Wolbachia infection on the fitness of Drosophila suzukii

Maternally inherited Wolbachia is prevalent among insects and is often linked with modifications of host fitness. The result and evolution of host symbiont interaction depend on environmental limits but are difficult to predict since they arise from complex interactions among host, parasite, and environment. In this study, we evaluated whether fitness traits of Wolbachia-free and Wolbachia-infected individuals of Drosophila suzukii (Matsumura) (Diptera Drosophilidae) were affected when flies were exposed to temperature stress (29 °C versus 22 °C) as well as to nutritional and starvation stress. Two lines of D. suzukii were prepared for the experiments: a Wolbachia-free line, treated with antibiotics, and a Wolbachia-infected line, hosting the endoparasite wSuz. Survival and fecundity of the two lines were assessed as well as the effect of nutritional stress on time of development and starvation stress on survival. Results showed that Wolbachia had a positive effect on egg hatch rates and viability at 29 °C, while at the same temperature there was a negative effect on adult survival. Wolbachia-free and Wolbachia-infected flies did not show any difference regarding nutritional and starvation stress. It is concluded that temperature associated changes in wSuz did not cause cytoplasmic incompatibility but significantly affected some fitness traits. This result may help to understand the performance of D. suzukii-Wolbachia-host-symbiont interaction in nature.
Structural and Functional Characterization of a Unique Hypothetical Protein ( Wp _ 000373624 . 1 ) Of Shigella Flexneri : A Computational Approach

Original Research Article Shigella is one of the most common reason for morbidity and mortality all through the world, causing around 125 million Shigellosis per year and an expected 14,000 deaths, generally among children‟s of <5 years of age. Bacillary dysentery, a very common bowl disease is caused by Shigella flexneri. The hypothetical protein of Shigella flexneri (>WP_000373624.1) was taken and analyzed for the determination of its molecular and structural characteristics. Additionally, we attempt to forecast a worthy model of >WP_000373624. 1 by utilizing in silico techniques related to protein homology and prediction of active sites to develop effective treatment against Shigella flexneri. Pyre2 software was used for the 3D structural analysis through homology modeling. The functional annotation was also performed by CDD Blast. This in silico hypothetical protein analysis can be additionally exploited in molecular drug strategy for other clinically important pathogens.
Saliency Prediction for Omnidirectional Images

There exist several state of the art methods to predict the saliency maps for 2D flat images. However these cannot be directly extended to predict the saliency maps for omnidirectional (360) images in the Equirectangular projection because of the large amount of distortion. This work proposes a model to interpret and predict the saliency maps for equirectangular images using existing conventional 2D saliency predictors. The “Salient360! ” grand challenge dataset [1,2] for Head-eye saliency was used to perform all the experiments and competitive results were achieved.
Wireless Communication Base Station-Based Indoor 3 D Target Positioning Research

In this paper, the improved Chan algorithm based on signal TOA data (the improvement using the weighted minimum mean square error method) is used to calculate the terminal position coordinates, and then the partial least squares regression analysis is used to perform regression analysis and error modeling on the position coordinate results. Finally, an accurate estimation of the three-dimensional position coordinates of the terminal is obtained. According to the model solution, the algorithm designed in this paper can effectively eliminate the non-line-of-sight propagation environment (NLOS) error and obtain an accurate estimation of the terminal position.
Mixed Dual Band Digital Predistortion Model Based on DDR

Due to the development of the multi standard communication system, digital predistortion linearization technology for concurrent dual band power amplifier has attracted a lot of attention in recent years. This paper proposes a mixed dual band digital predistortion model based on DDR, which extends the traditional DDR model to synchronic dual band mode, with the introduction of two dimensional memory polynomial model with same order envelope cross term, to enhance the compensation ability for the nonlinear intermodulation distortion in the dual band power amplifier, which can achieve better modeling precision and linearization performance than the simplified two-dimensional memory polynomial model and the traditional DDR model, while at the same time maintain the advantages easy to realize by using the one-dimensional lookup table. Experiments show that the New Model has good level in both performance and complexity.
