A Submodular Optimization Framework for Outage-Aware Cell Association in Heterogeneous Cellular Networks

In cellular heterogeneous networks (HetNets), offloading users to small cell base stations (SBSs) leads to a degradation in signal to interference plus noise ratio (SINR) and results in high outage probabilities for offloaded users. In this paper, we propose a novel framework to solve the cell association problem with the intention of improving user outage performance while achieving load balancing across different tiers of BSs. We formulate a combinatorial utility maximization problem with weighted BS loads that achieves proportional fairness among users and also takes into account user outage performance. A formulation of the weighting parameters is proposed to discourage assigning users to BSs with high outage probabilities. In addition, we show that the combinatorial optimization problem can be reformulated as a monotone submodular maximization problem and it can be readily solved via a greedy algorithm with lazy evaluations. The obtained solution offers a constant performance guarantee to the cell association problem. Simulation results show that our proposed approach leads to over 30% reduction in outage probabilities for offloaded users and achieves load balancing across macrocell and small cell BSs.
THE LIKELIHOOD OF SHEEP MEAT CONSUMPTION IN TURKEY

The aims of this study are threefold: first, to determine the factors affecting the likelihood of sheep meat consumption; second, to determine the reasons for consumers’ preferences; and third, to determine consumers’ willingness to pay for quality-based labelling. The study conducted interviews with 300 households in Izmir province. According to the results of logistic regression analysis, gender, level of income, number of people in the household, beef consumption, and whether the interviewed individual has the highest income in his or her household affect the probability of sheep meat consumption. While the personal preferences of regular sheep meat consumers vary according to their red meat consumption, willingness to pay based on labelling is $1.62/kg.
The Structure of Rural Landscape in Monetary Evaluation Studies: Main Analytical Approaches in Literature

Over recent years considerable research has been devoted to the assessment of the rural landscape value. These studies have concerned both use and non-use value estimation. An important issue in monetary evaluations is about taking (or not) into account the structural complexity of landscape. Three analytical approaches may be recognized on the basis of whether landscape structural attributes are involved (global, mono-attribute and multi-attribute approach). The present work is part of a research aimed to seek out rational instruments for guidance policies on rural landscape. It consists in a survey of the main studies appeared in literature. The specific purpose is to classify these empirical analyses in accordance both to the approaches mentioned above and to the landscape typologies (agricultural or forestry) involved.
SUGAR BEET (Beta vulgaris L.) HAPLOID PARTHENOGENESIS in vitro: FACTORS AND DIAGNOSTIC CHARACTERS

Traditional obtaining of inbred lines and hybrids in sugar beet breeding requires a long time and is labour-consuming because of 2-year cycle of plant development, selfand cross-incompatibility, and inbreeding depression. To induce genotypic diversity in initial population, biotechnology methods including haploid parthenogenesis are promising. We have shown that, when inducing sugar beet (Beta vulgaris L.) haploids in vitro, express-diagnostics using phenotypic and embryological characters that are representative of periods of flowering shoots, organs and buds development, and stages of embryo sac, ovule and pollen grains formation is effective. The regenerative activity is observed in ovules of bud 1 to bud 25 located on ear part of pleochasium upward from the open flower. The nuclei and cells of female gametophyte of isolated ovules under in vitro conditions are capable of neoplasm at all stages of development, but the 8-nuclear or 7-celled embryo sacs are the most appropriate to morphogenesis and switching of development program from gametophyte to sporophyte type. Critical period of embryo sac development has been beforehand determined from the accompanying embryological characters — the presence of single-nuclear and two-three-celled pollen grains of anthers located in the same bud as ovules. The results we obtained indicate that hormonal composition of the Gamborg's B-5 (B5) medium is an important factor that effectively regulates direction of morphogenetic development in isolated ovules through direct regeneration (embryoidogenesis) or via callus (hemorhizogenesis) that is the evidence of totipotency of both sexual and somatic cells in the explant. The obtained data on in vitro reproduction of haploid regenerants add to available scientific notion of morphogenetic potential specificity in sugar beet plants. Stabilizing selection used to produce double haploids promotes detection of valuable morphological features of the regenerants. Determination of chromosome and chloroplast numbers in stomata guard cells as well as isozyme electrophoretic mobility (for Adh-1, Mdh-1, Mdh-2, Me-1, Idh-1, Idh-2, Gdh-1 loci) can serve as markers when inducing haploidy and producing homozygous restitution lines of sugar beet. Efficiency of RFLP-analysis method using Hind III restrictase that has allowed for the first time to identify haploid microclones according cytoplasm type is shown. Molecular markers have indicated that regenerants with normal cytoplasm (N) have one PCR-product of 800 bp in length not digested by Hind III. Two fragments (320 bp and 480 bp) of 800 bp product digestion are found in cytoplasmic male sterile (CMS) forms (S) that reflects combination of recessive and dominant genes. Obtaining haploid regenerants with sterile cytoplasm from initial population is of great theoretical and practical importance for sugar beet breeding thus facilitating the problem of producing homozygous lines with CMS and high-productive hybrids on the sterile basis.
Substation Inspection System for Temperature Measurement and Automatic Fault Location Based on Dual-channel Images

Overheating and radiation from power equipment is a crucial factor for a variety of failures and anomalies. This paper presents a substation inspection system based on computer and embedded system for temperature measurement and smart fault location for power equipment, to improve the reliability and security of smart grid by effectively combining video surveillance, infrared temperature measurement, and image processing techniques. The accuracy for the temperature measurement was within one degree. With the registration of infrared image and visible image, the fault location can be located automatically. The RMES error for registration between visible image and infrared image was less than one pixel. The time cost is much lesser compared with other image registration methods. Thus, a comprehensive realtime on-line monitoring and smart fault location is achieved. With the accuracy, validity, and efficiency improved, grid maintenance and management is simpler and more economical.

Preparation and evaluation of polymeric carbamazepin spherical crystals by emulsion solvent diffusion technique

In this study, a significant effect of different polymers on improving the solubility, dissolution rate, and physicochemical properties of carbamazepine (CBZ) has been demonstareted by emulsion solvent diffusion technique, with ethanol– chloroform–water as the solvent system. The hydrophilic polymers like polyethylene glycol, chitosan, and hydrophobic polymer Eudragit RSPO were used in the recrystallization process. The pure drug CBZ and the prepared spherical crystals of CBZ with different polymers were characterized in terms of morphology (microscopical photograph), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), drug contents, solubility, dissolution rate, crushing strength, wettability, flowability, and packability. The FTIR spectra of the prepared spherical crystals showed that changes in the chemical nature occur and do not present great fingerprint difference. The XRD also revealed a characteristic decrease in crystallinity. The solubility and dissolution studies demonstrated a marked increase in solubility and dissolution rate in comparison with the pure drug. The prepared spherical crystals with different polymers exhibited excellent physicochemical properties like flowability, packability, and wettability compared with the pure drug. The spherical crystals with polyethylene glycol and chitosan showed higher crushing strength when compared with the hydrophobic polymer (Eudragit RSPO).

Malaysian Worries: Manufacturing Management Caught in the Middle?

Whereas the academic view on the contribution of manufacturing to competitive strategies has undergone a paradigm shift, or even possibly some, the question is whether practice has changed really. Three workshops in Malaysia reveal that manufacturing managers have troubles implementing their strategies. That is caused for part by the position of their companies in the supply chain, for part by the pressures caused by sales departments causing focus on the here and now, and for part by the undervaluing of the manufacturing function. That leads to deliberations whether much has changed since Skinner’s seminal works in 1966, 1969 and 1974.
Amniotic Fluid-Derived Stem Cells (AFSC) and Their Application in Cell Therapy and Tissue Engineering

Context: Amniotic Fluid Derived Stem Cells (AFSC) has mesenchymal origin and is multipotent. Having played their role in the detection of genetic abnormalities in the unborn children, they are gaining attention in the regenerative medicine because of their pluripotency. Evidence Acquisition: AFSCs possess great proliferating ability and have no ethical and religious issues in their use. AFSCs may also be studied for the stem cells differentiation such as production of multiple lineages of different cells like heart, liver, pancreas, etc. The potential of their use in regenerative medicine as well as their differentiation into multiple cells is possible. Results: AFSCs have the potential to be used in tissue repair and regeneration of bladder and kidney injuries, for the treatment of congenital anomalies like tracheal anomalies and spina bifida therapy etc. However, like every therapeutic potential, AFSCs also have some limitations such as low rate of differentiation of transplanted AFSCs and immune rejection. Conclusions: AFSCs have great therapeutic potential, but extensive research is warranted to overcome the limitations to use AFSC as therapy.
Constraint Based Periodicity Mining in Time Series Databases

The search for the periodicity in time-series database has a number of application, is an interesting data mining problem. In real world dataset are mostly noisy and rarely a perfect periodicity, this problem is not trivial. Periodicity is very common practice in time series mining algorithms, since it is more likely trying to discover periodicity signal with no time limit. We propose an algorithm uses FP-tree for finding symbol, partial and full periodicity in time series. We designed the algorithm complexity as O (kN), where N is the length of input sequence and k is length of periodic pattern. We have shown our algorithm is fixed parameter tractable with respect to fixed symbol set size and fixed length of input sequences. Experiment results on both synthetic and real data from different domains have shown our algorithms' time efficient and noise-resilient feature. A comparison with some current algorithms demonstrates the applicability and effectiveness of the proposed algorithm.
Microparticles released by Ectocytosis from Human Neutrophils : Characterisation , Properties and Functions

Human neutrophils release vesicles when activated in vitro and in vivo, in local and systemic inflammation. We have suggested that the presence of these vesicles is due to ectocytosis, defined as the release of rightside-out oriented vesicles expressing a select set of membrane proteins. Herein we have characterised the vesicles released by neutrophils to be ectosomes with specific properties. They contained cytosolic F-actin indicating their outside-out orientation. They bound AnnexinV suggesting that they expose phosphatidyl-serine, similarly to platelet-microparticles. They expressed a subset of cell surface proteins (selectins and integrins, complement regulators, HLA-1, FcγRIII and CD66b but not CD14, FcγRII and CD87). There was no specificity for transmembrane or glycosyl-phosphatidylinositol-linked proteins and unexpectedly L-selectin, known to be cleaved from the surface of activated neutrophils, was present. Ectosomes exposed active enzymes released by neutrophils upon degranulation (matrix metalloproteinase-9, myeloperoxidase, proteinase 3 and elastase). In particular, released myeloperoxidase was able to bind back to ectosomes. The purified complement protein C1q and C1q from serum bound to ectosomes as well. Another aspect of ectosomes was that they became specifically adherent to monocytic and endothelial cells. These observations suggest that neutrophil-derived ectosomes have unique characteristics making them candidates to play roles in inflammation and cell signaling.
Claw diseases and lameness in Polish Holstein-Friesian dairy cows.

The objective of this study was to estimate the influence of age (parity) and housing system on the incidence of claw lesions and lameness in Polish Holstein-Friesian dairy cows. The incidence of hoof lesions and lameness in 1,330 cows was determined at claw trimming at 11 dairy farms in 2003-2004. In the front limbs, the mean of healthy claws was 86.6%, while in the hind limbs, it was 38.7%. The percentage of main diseases in the total number of observed claw lesions was 32.1% for sole ulcers, 18.4% for sole haemorrhage, 17.8% for digital dermatitis, 9.4% for white line disease, 8.1% for thick hock, and 4.5% for interdigital dermatitis. Primarily, the sole ulcers were associated with sole haemorrhage, white line disease, interdigital growth, interdigital dermatitis, and thick hock. The incidence of lameness was noted in 31.4% (locomotion score 2) and 11.7% (locomotion score 3). Parity and housing systems (tethered and free stalls) had no effect on the total percentage of healthy claws and the distribution of the locomotion score. The incidence of sole ulcers was 47.6% and 55.4% of the total numbers of claw lesions in cows with locomotion scores 2 and 3 respectively.
Validation of sheep rumen fluid frozen in liquid N as inoculum for in vitro gas production trials

The effect of freezing rumen fluid in liquid nitrogen for its use as inoculum for in vitro incubation was evaluated in a semi-continuous system. Inoculum was used immediately (RF) or frozen and then thawed and used (TW) or preincubated for 2 (TW2) or 4 h (TW4) before substrate addition. For TW4, a sugars mixture was added. Bacterial diversity was not greatly affected by the inoculum processes. There were no differences on cumulative gas production (ml/g DM) or rate of gas production (ml/g DM per h) between RF and TW along the 36 h incubation (P>0.05). Delayed inocula (TW2 and TW4) produced less gas than RF up to 12h (P<0.05), but differences in fermentation rate were only appreciable at 2, 20 and 24 h (P<0.05). Volatile fatty acids (VFA) concentration at 6 h was higher with RF than TW and TW4, being lowest with TW2 (P=0.007) whereas at 24h it tended (P=0.07) to be higher with TW than with TW2 and TW4. Butyrate and minor VFA proportions differed for RF and frozen treatments at 6 and 24h (P<0.05). Despite of this, rumen fluid frozen in liquid N behaved similarly than fresh inoculum in terms of in vitro substrate fermentation. The lower gas volume in TW2 and TW4 might be justified by soluble nutrients utilisation during the first 2 and 4h incubation.
Data Science and symbolic AI: Synergies, challenges and opportunities

Symbolic approaches to Artificial Intelligence (AI) represent things within a domain of knowledge through physical symbols, combine symbols into symbol expressions, and manipulate symbols and symbol expressions through inference processes. While a large part of Data Science relies on statistics and applies statistical approaches to AI, there is an increasing potential for successfully applying symbolic approaches as well. Symbolic representations and symbolic inference are close to human cognitive representations and therefore comprehensible and interpretable; they are widely used to represent data and metadata, and their specific semantic content must be taken into account for analysis of such information; and human communication largely relies on symbols, making symbolic representations a crucial part in the analysis of natural language. Here we discuss the role symbolic representations and inference can play in Data Science, highlight the research challenges from the perspective of the data scientist, and argue that symbolic methods should become a crucial component of the data scientists’ toolbox.
Computer simulation of ESD from voluminous objects compared to transient fields of humans

Computer simulation of electrostatic discharge (ESD) for simplified objects is described and compared to measured transient fields of human/metal ESD. The simulation algorithm uses the method of moments in time domain, coupled with nonlinear arc resistance model. Transient currents and fields are analyzed from the electromagnetic compatibility (EMC) point of view. Validation of the numerical simulation is done by comparison to experimental data. The simulated structure models the human/metal ESD in its peak current and field values and their derivatives reasonably well.
Polymer Scavenging and Profile of E. coli 0111:B4 Lipopolysaccharide by MALDI-TOF

Lipopolysaccharide is a component of the cell membrane of Gram negative bacteria and is a pro-inflammatory substance; small amounts present in the blood can be fatal to mammals. Scavenging of lipopolysaccharide from plasma has been attempted previously but the use of molecularly imprinted polymers for this purpose has not been described before. This preliminary study utilized a single lipopolysaccharide type to investigate scavenging by molecular polymers and used Matrix Assisted Laser Desorption/Ionization Time-of-Flight (MALDI-TOF) to detect such scavenging. Commercially available LPS from E. coli O111:B4 was subjected to MALDI-TOF analysis to detect LPS profiles in solutions containing pure LPS or solutions that had been exposed to imprinted and non-imprinted polymers with scavenging potential. The current research suggests potential for molecularly imprinted polymers to be used as scavengers of LPS, although the imprinting protocols need optimization. MALDI-TOF is a suitable method for detection of LPS profiles and LPS elimination from samples.
Molecular detection of Candidatus liberibacter asiaticus associated with Citrus greening (Huanglongbing) of mandarin by DNA template preparation

The polymerase Chain Reaction (PCR) diagnosis is more reliable and sensitive diagnostic tool for detecting greening bacterium than other conventional approaches like Electron microscopy, DNA-DNA hybridization and immunofluorescence (IF) for detection of citrus greening. During experiments, it was observed that sodium sulphite method of DNA isolation provided higher yield and better quality DNA than other methods. Primer C (450 bp) was more efficient in amplifying the DNA of greening bacterium even at a very low concentration of 0.1 pg. To confirm the reliability of PCR, the greening bacterium was also detected in graft-inoculated plants, which showed typical greening bacterium was also detected in graft-inoculated plants, which showed typical greening symptoms. Results showed amplification of 450 bp in PCR suggesting sampling in March is more suitable for PCR detection of greening bacterium.
Employees Perception of Training and Its Relationship with Organizational Commitment among the Employees Working at Saudi Industrial Development Fund

The aim of this study is to examine employees perception of training provided by Saudi Industrial Development Fund (SIDF) and its relationship with organizational commitment. To achieve this aim, the study utilized a questionnaire consists of two validated, well established, international instruments: the first one is the perceived availability of training developed by Newman et al., (2011) and includes 22-item inventory that measures an individual on the training, the second instrument called commitment scale developed by Allen and Meyer, (1996) and includes 18-item inventory to identify a person’s commitment. This questionnaire has been distributed to a simple random sample consist of (200) employees of Saudi Industrial Development Fund. A total of (175) complete questionnaires has been received back at a response rate of (87%). After analyzing data and testing hypotheses, the main results of this study are: • There is a positive relationship between five training-related variables and affective commitment. • There is a positive relationship between two training-related variables (the perceived availability of training and perceived supervisor support for training) and two commitment-related variables (continuance and normative commitment). • There is a negative relationship between perceived co-worker support for training and two commitment-related variables (continuance and normative commitment). • There is no relationship between two training-related variables (the perceived benefits of training and motivation to learn) and two commitment-related variables (continuance and normative commitment).
The Effect of Sn and TiO 2 Nano Particles Added in Electroless Ni-p Plating Solution on the Properties of Composite Coatings.

Ni-P/TiO2 and Ni-Sn-P/TiO2 nano composite coatings with various contents of TiO2 nano particles were prepared by electroless technique from Ni-P plating bath containing TiO 2 powder were kept in suspension by stirring. The composite film was characterized by thin film ((PANLYTICAL, X Pert PRO), scanning electron microscope (SEM), energy dispersive X-ray (EDX) technique and X ray diffraction have been applied in order to investigate the chemical composition and phase structure of the coatings. The corrosion resistance of Ni-P/TiO2 and Ni-Sn-P/TiO2 film was studied by potentiodynamic polarization in 3.5% sodium chloride solution. The results indicate that Ni-P/TiO2 and Ni-Sn-P/TiO2 composite film have good corrosion resistance. Electroless deposited composite coatings exhibit an amorphous structure of the nickel matrix and after heat treatment lead to a crystalline microstructure in which the Ni and Ni3P crystallites appear apart from those of the TiO2, with very good adhesion to the substrate.
Interbull checks of international breeding values

The first method used to verify the international breeding values is the comparison of current and previous international evaluations. This comparison is done for each country scale involving all bulls with an international breeding value. The intenational breeding values are calculated using the MACE model according to Schaeffer (1994) and reliabilities of international breeding values are approximated according to Harris and Johnson (1998).
