The nucleoplasmin family of histone chaperones is identified by a pentamer-forming domain and multiple acidic tracts that mediate histone binding and chaperone activity. Within this family, a novel domain organization was recently discovered that consists of an N-terminal nucleoplasmin-like (NPL) domain and a C-terminal FKBP peptidyl-proline isomerase domain. Saccharomyces cerevisiae Fpr4 is one such protein. Here we report that in addition to its known histone prolyl isomerase activities, the Fpr4 FKBP domain binds to nucleosomes and nucleosome arrays in vitro. This ability is mediated by a collection of basic patches that enable the enzyme to stably associate with linker DNA. The interaction of the Fpr4 FKBP with recombinant chromatin complexes condenses nucleosome arrays independently of its catalytic activity. Based on phylogenetic comparisons we propose that the chromatin binding ability of ‘basic’ FKBPs is shared amongst related orthologues present in fungi, plants, and insects. Thus, a subclass of FKBP prolyl isomerase enzymes is recruited to linker regions of chromatin.

Published: June 2017

We report on the IR sensitivity enhancement of back-illuminated CMOS Image Sensor (BI-CIS) with 2-dimensional diffractive inverted pyramid array structure (IPA) on crystalline silicon (c-Si) and deep trench isolation (DTI). FDTD simulations of semi-infinite thick c-Si having 2D IPAs on its surface whose pitches over 400 nm shows more than 30% improvement of light absorption at λ = 850 nm and the maximum enhancement of 43% with the 540 nm pitch at the wavelength is confirmed. A prototype BI-CIS sample with pixel size of 1.2 μm square containing 400 nm pitch IPAs shows 80% sensitivity enhancement at λ = 850 nm compared to the reference sample with flat surface. This is due to diffraction with the IPA and total reflection at the pixel boundary. The NIR images taken by the demo camera equip with a C-mount lens show 75% sensitivity enhancement in the λ = 700–1200 nm wavelength range with negligible spatial resolution degradation. Light trapping CIS pixel technology promises to improve NIR sensitivity and appears to be applicable to many different image sensor applications including security camera, personal authentication, and range finding Time-of-Flight camera with IR illuminations.

The role of the zinc transporter SLC30A2/ZnT2 in transient neonatal zinc deficiency
Authors: Golan Yarden , Kambe Taiho , Assaraf Yehuda G.
Published: June 2017

Transient neonatal zinc deficiency (TNZD) results from loss of function mutations in theSLC30A2/ZnT2gene. Nursing mothers harboring this defective zinc transporter produce zinc-deficient milk. Consequently, their exclusively breastfed infants develop severe zinc deficiency. The present review summarizes our current knowledge onSLC30A2/ZnT2gene mutations and highlights the molecular mechanisms underlying this zinc deficiency. We further propose novel approaches for the early diagnosis and prevention of TNZD.

miRNA-340 inhibits osteoclast differentiation via repression of MITF
Authors: Zhao Hongying , Zhang Jun , Shao Haiyu , Liu Jianwen , Jin Mengran , Chen Jinping , Huang Yazeng
Published: June 2017

Many miRNAs play critical roles in modulating various biological processes of osteoclast differentiation and function. Microphthalmia-associated transcription factor (MITF), a target of miR-340, served as pivotal transcription factor involved in osteoclast differentiation. However, the role of miR-340 and MITF during osteoclast differentiation has not yet been clearly established. Tartrate-resistant acid phosphatase (TRAP) staining assay was performed to identify osteoclasts differentiated from bone marrow-derived macrophages (BMMs). Quantitative reverse transcription PCR (qRT-PCR) or Western blotting was undertaken to examine the mRNA or protein expression respectively. Luciferase reporter assay was performed to investigate the interaction between miR-340 and MITF. MITF was knocked down and miR-340 was overexpressed and transfected into BMMs to detect their effects on osteoclast differentiation. Firstly, qRT-PCR analysis showed that miR-340 was down-regulated during osteoclast differentiation stimulated by macrophage-colony stimulating factor (M-CSF) and receptor activator of nuclear factor (NF)-κB (RANK) ligand (RANKL). Besides, we found that overexpression of miRNA-340 inhibited osteoclast differentiation and suppressed both the mRNA and protein level of MITF. Finally, Western blot and qRT-PCR analysis revealed that silencing MITF inhibited TRAP, calcitonin receptor, V-ATPase d2, and cathepsin K. miR-340 suppresses osteoclast differentiation by inhibiting MITF. Our findings may provide promising therapeutic targets for osteoclast-associated diseases.

Published: June 2017

Purpose

To produce a novel, efficient measure of children's expressive vocal development on the basis of automatic vocalization assessment (AVA), child vocalizations were automatically identified and extracted from audio recordings using Language Environment Analysis (LENA) System technology.

Method

Assessment was based on full-day audio recordings collected in a child's unrestricted, natural language environment. AVA estimates were derived using automatic speech recognition modeling techniques to categorize and quantify the sounds in child vocalizations (e.g., protophones and phonemes). These were expressed as phone and biphone frequencies, reduced to principal components, and inputted to age-based multiple linear regression models to predict independently collected criterion-expressive language scores. From these models, we generated vocal development AVA estimates as age-standardized scores and development age estimates.

Result

AVA estimates demonstrated strong statistical reliability and validity when compared with standard criterion expressive language assessments.

Conclusions

Automated analysis of child vocalizations extracted from full-day recordings in natural settings offers a novel and efficient means to assess children's expressive vocal development. More research remains to identify specific mechanisms of operation.
Bias‐compensated robust set‐membership NLMS algorithm against impulsive noises and noisy inputs
Authors: Zheng Zongsheng , Liu Zhigang , Lu Lu
Published: June 2017

By minimising a new cost function that contains robust set‐membership error bound, a bias‐compensated robust set‐membership normalised least mean square (NLMS) algorithm is proposed, which is characterised by its robustness against impulsive noises and noisy inputs. To estimate the input noise variance in impulsive noise environments, a new estimation method is proposed in which there is no need to know the input–output noise variance ratio in advance. Simulations in a system identification context demonstrate that the proposed algorithm achieves improved robustness and better performance than the existing algorithms.

The synthetic biology design process has traditionally been heavily dependent upon manual searching, acquisition and integration of existing biological data. A large amount of such data is already available from Internet‐based resources, but data exchange between these resources is often undertaken manually. Automating the communication between different resources can be done by the generation of computational workflows to achieve complex tasks that cannot be carried out easily or efficiently by a single resource. Computational workflows involve the passage of data from one resource, or process, to another in a distributed computing environment. In a typical bioinformatics workflow, the predefined order in which processes are invoked in a synchronous fashion and are described in a workflow definition document. However, in synthetic biology the diversity of resources and manufacturing tasks required favour a more flexible model for process execution. Here, the authors present the Protocol for Linking External Nodes (POLEN), a Cloud‐based system that facilitates synthetic biology design workflows that operate asynchronously. Messages are used to notify POLEN resources of events in real time, and to log historical events such as the availability of new data, enabling networks of cooperation. POLEN can be used to coordinate the integration of different synthetic biology resources, to ensure consistency of information across distributed repositories through added support for data standards, and ultimately to facilitate the synthetic biology life cycle for designing and implementing biological systems.
High‐throughput signal detection based on fast matrix inversion updates for uplink massive multiuser multiple‐input multi‐output systems
Authors: Deng Qian , Guo Li , Dong Chao , Lin Jiaru , Meng Dedan , Chen Xueyan
Published: June 2017

In this study, zero‐forcing matrix decomposition polynomial expansion update (ZF‐MDPE‐update) and zero‐forcing successive over relaxation update (ZF‐SOR‐update) algorithms are proposed to update a zero‐forcing detector quickly without requiring complicated matrix inversion recomputations when massive multiple‐input multi‐output systems channel estimates contain a small perturbation. To further accelerate the convergence rate and to maximise date throughput, a new method of calculating the optimal coefficients for the matrix polynomial that can significantly improve the accuracy of the initial input inverse matrix approximation is considered by the ZF‐MDPE‐update algorithm. On the other hand, the ZF‐SOR‐update algorithm with an optimal iterative initial solution and an optimal relaxation parameter is devised, which achieves excellent detection performance. Results demonstrate that when the ratio of base station (BS) antennas to user terminal (UT) antennas, , is small, the proposed update detection algorithms, with only a few operations, achieve a significant improvement in the average achievable rate of the UTs compared to the recently proposed update algorithm. Therefore, more UTs can be served in a cell with a fixed number of BS antennas. At the same time, the authors' algorithms are shown to facilitate easy memory transfer and are low cost.
Design of fault current limiter using core with low initial permeability
Authors: Guney Onur , Cansiz Ahmet
Published: June 2017

Increasing electrical energy consumption and associated power grid expansion tend to increase the level of the fault currents in power systems. Maintaining proper functioning of the grid requires fault currents to be at an acceptable level using appropriate fault current limiting techniques. Most of the fault current limiter devices work in a saturated core region during normal operation mode. Since the continuous saturation core also requires continuous energy supply, the use of the cores that operate at low initial permeability region is a suitable candidate with no power consumption. For this purpose, the potential use of the SAE 1020 low carbon steel in the fault current limiter is investigated. The design simulation is carried out in terms of required shape, dimensions and parameters by using finite element analysis. The dimension of the fault current limiter is optimised by introducing air gaps into the core, while keeping the performance of the fault current limiter device unchanged. The simulation results indicate that the proposed design with air gaps still has a better current limiting performance compared to the coil with pure air core. Reducing the dimensions of the device is achievable in the expense of its performance.
Differential‐privacy preserving optimal power flow in smart grid
Authors: Yang Zequ , Cheng Peng , Chen Jiming
Published: June 2017

In smart grid, the smart meters improve the grids’ efficiency but imply the sensitive residential information. Hence, how to prevent privacy leakage of smart meter data has drawn lots of researchers’ attentions. Yet, it is non‐trivial to quantify the relation between privacy protection behaviours and system utility loss. To this end, the authors leverage the notion of differential privacy (DP) to measure the privacy‐protection strength, under the framework of optimal power flow (OPF). Specifically, once the noise is injected to hide the actual demand, the solutions of OPF problem are probably affected, which undermine the grid utility. In this study, the authors are the first quantitatively investigating DP preserving OPF problem. Starting with re‐modelling the noise‐injected OPF problem, the authors rigorously prove OPF solution's sensitivity with respect to the uncertainty of demand. Moreover, aiming at OPF‐based pricing mechanism, locational marginal pricing (LMP), the respective privacy‐protection's contribution on LMPs is explicitly expressed. Subsequently, based on the extensive experiments, it is illustrated that the quantitative correlation between the privacy‐protection strength and the gird system performance. Furthermore, by combining the grid topology and privacy‐protection strength, a novel billing system to fairly charge the extra payment to subsidise the privacy‐insensitive customers is proposed.
Low‐complexity face recognition using contour‐based binary descriptor
Authors: Lin Jou , Chiu Ching‐Te
Published: June 2017

Face recognition has become a popular topic due to its applications in security, surveillance and so on. Current local methods such as the local binary pattern (LBP) or local derivative pattern (LDP) perform better than holistic methods since they are more stable on local changes such as misalignment, expression or occlusion, but their high computational complexity limit their applications. While LBP is a good feature method, the scale invariant feature transform (SIFT) is widely accepted as one of the best features to capture edge or local shape information. However, SIFT‐based schemes are sensitive to illumination variation. Thus, the authors propose an LBP edge‐mapped descriptor that uses maxima of gradient magnitude points. It accurately illustrates facial contours and has low computational complexity. Under variable lighting, experimental results show that the authors' method has a 16.5% higher recognition rate and requires 9.06 times less execution time than SIFT under FERET fc. Besides, when applied to the Extended Yale Face Database B, the authors' method outperformed SIFT‐based approaches as well as saving about 70.9% in execution time. In uncontrolled conditions, their method has a 0.82% higher recognition rate than LDP histogram sequences in the Unconstrained Facial Images database.
Histogram of Radon transform and texton matrix for texture analysis and classification
Authors: Di Ruberto Cecilia
Published: June 2017

In this study, the authors introduce a new and efficient method to classify texture images. From the histogram of the Radon transform, a texture orientation matrix is obtained and combined with a texton matrix for generating a new type of co‐occurrence matrix. From the co‐occurrences matrix, 20 statistical features for texture images classification have been extracted: seven statistics of the first‐level order and 13 of the second‐level one. K‐Nearest neighbour and support vector machine models are used for classification. The proposed approach has been tested on widely used texture datasets (Brodatz and University KTH Royal Institute of Technology Textures under varying Illumination, Pose and Scale) and compared with several different alternative methods. The experimental results show a very high‐accuracy level, confirming the strength of the developed method which overcomes the state‐of‐the‐art methods for texture classification.
Convex‐relaxed active contour model based on localised kernel mapping
Authors: Cui Wenchao , Gong Guoqiang , Lu Ke , Sun Shuifa , Dong Fangmin
Published: June 2017

Intensity inhomogeneity is one of the major obstacles for intensity‐based segmentation in many applications. The recently proposed kernel mapping (KM) method has exhibited excellent performance on segmenting various types of noisy images while it is not effective to handle intensity inhomogeneity. To overcome this drawback, this study presents a localised KM (LKM) method based on the fact that intensity inhomogeneity can be ignored in a local neighbourhood. The authors’ method first reconstructs the KM formulation of image segmentation in a neighbourhood of each pixel, and then such formulations for all pixels can be integrated together to derive the LKM energy functional. Minimisation of the energy functional is implemented by solving an equivalent convex‐relaxed problem whose optimisation can be quickly achieved via the split Bregman method. Experimental results on two‐phase segmentation and multiphase segmentation demonstrate competitive performance of the LKM method in the presence of intensity inhomogeneity and severe noise.
Early adopters of emergency braking and speed alert
Authors: Öörni Risto , Malin Fanny
Published: June 2017

We analyse the characteristics of early adopters of two intelligent vehicle safety systems, emergency braking and speed alert. Car users’ experiences with the two systems and the characteristics of early adopters of the systems were studied with an online survey organised in five European countries: Czech Republic, Finland, Germany, the Netherlands, and Spain. All of the studied variables related to the user – gender, age, kilometres driven annually and monthly household income – had a statistically significant relationship with using emergency braking. Gender, kilometres driven annually and monthly household income had a statistically significant relationship with using speed alert. For both systems, male drivers were more likely to be the first users of the systems. In general, the share of users having experienced the systems also increased with annual kilometrage and monthly household income. Younger, 18‐ to 44‐year‐old drivers were found more likely to have used emergency braking than older, 65‐ to 74‐year‐old drivers. The results, however, suggest that respondents’ annual kilometrage and monthly household income may be more strongly associated with using the systems than with age.
Gain improvement of cylindrical dielectric resonator antenna using flat reflector plane: a new approach
Authors: Dash Sounik Kiran Kumar , Khan Taimoor , Kanaujia Binod Kumar , Antar Yahia M.M.
Published: June 2017

A significantly feasible high‐gain cylindrical dielectric resonator antenna with wideband characteristics is investigated. A simple microstrip‐fed slot coupling technique is adopted for excitation of the cylindrical resonator, which is placed over a square slot made at the centre of the ground plane. The upper side of the dielectric resonator is kept open for interference free radiation. To reduce the unnecessary back radiation, the bottom side of the ground plane substrate is covered by a single side copper coated dielectric reflector (1.35λ0 × 1.35λ0 × 0.04λ0) at a small air‐gap distance of 4 mm. This helps in abrupt gain enhancement of 101.48% over 17.14% impedance bandwidth. The effect of the reflector on bandwidth, gain and radiation pattern is studied. For validation purpose, a prototype is fabricated and characterised. The measured peak gains are found to be 10.84 and 10.45 dB while resonating at 7.3 and 8.08 GHz, respectively, which are in good agreement with their simulated counterparts.
Technical risk factors of international construction
Authors: Martin Asare , Wang Yousong , Li Jianfeng , Mends George
Published: June 2017

Construction is one of the strongholds for development in every country. The objective of the research is to identify the critical technical risk factors encountered by engineering firms on the global milieu. Based on questionnaire surveys, statistical analyses and previous studies on risk management, 23 risks were selected and ranked as technical factors that hinder construction projects. The relative importance index (RII) was used to determine the rank of each factor surveyed. The study revealed that industrial disputes, shortage in power supply, shortage in supply of water and problems of partner difference practice of construction globally were among the highly ranked technical risks. The study is beneficial as it adopts case studies in Africa to elicit the technical effects on the international frontlines. With the ranking of the technical risk factors, international construction firms can adequately enhance critical planning, avoid casualties and engage in economically viable projects. The study will be useful for analysing and investigating the hypothesised relationships technical risk variables that influence performance of international joint ventures. The risk factors displayed in the study can be used in supporting data for many other research development studies in the area of construction, risk analysis and global construction development studies.
Use of “e” and “g” operators to a fuzzy production inventory control model for substitute items
Authors: Khatua Debnarayan , De Anupam , Maity Kalipada , Kar Samarjit
Published: June 2017

In this paper, a fuzzy optimal control model for substitute items with stock and selling price dependent demand has been developed. Here the state variables (stocks) are assumed to be fuzzy variables. So the proposed dynamic control system can be represented as a fuzzy differential system which optimize the profit of the production inventory control model through Pontryagin’s maximum principle. The proposed fuzzy control problem has been transformed into an equivalent crisp differential system using “e” and “g” operators. The deterministic system is then solved by using Newton’s forward-backward method through MATLAB. Finally some numerical results are presented both in tabular and graphical form.
Multi-objective and discrete Elephants Herding Optimization algorithm for QoS aware web service composition
Authors: Chibani Sadouki Samia , Tari Abdelkamel
Published: June 2017

The goal of QoS aware web service composition (QoS-WSC) is to provide new functionalities and find a best combination of services to meet complex needs of users. QoS of the resulting composite service should be optimized. QoS-WSC is a global multi-objective optimization problem belonging to NP-hard class given the number of available services. Most of existing approaches reduce this problem to a single-objective problem by aggregating different objectives, which leads to a loss of information. An alternative issue is to use Pareto-based approaches. The Pareto-optimal set contains solutions that ensure the best trade-off between conflicting objectives. In this paper, a new multi-objective meta-heuristic bio-inspired Pareto-based approach is presented to address the QoS-WSC, it is based on Elephants Herding Optimization (EHO) algorithm. EHO is characterised by a strategy of dividing and combining the population to sub population (clan) which allows exchange of information between local searches to get a global optimum. However, the application of others evolutionary algorithms to this problem cannot avoids the early stagnancy in a local optimum. In this paper a discrete and multi-objective version of EHO will be presented based on a crossover operator. Compared with SPEA2 (Strength Pareto Evolutionary Algorithm 2) and MOPSO (Multi-Objective Particle Swarm Optimization algorithm), the results of experimental evaluation show that our improvements significantly outperform the existing algorithms in term of Hypervolume, Set Coverage and Spacing metrics.
Recycling of lifetime dependent deteriorated products through different supply chains
Authors: Iqbal Muhammad Waqas , Sarkar Biswajit
Published: June 2017

Conservation of natural resources in order to protect the environment, support the economy, and offer a better life to living beings has become an urgent need of modern business so that future generations can survive within available resources and in a healthy environment. Recycling of used products plays an important role in the conservation of natural resources and the development of sustainable business for deteriorating products because the number of these items increases with time, which creates economic loss and environmental pollution. This paper considers the production and cycle time as decision variables to design a forward and reverse supply chain system that produces two different types of products, which are subject to deterioration. Rate of deterioration is time-varying and depends on the maximum lifetime of products. Used products of a forward supply chain are collected and treated as raw materials in a reverse supply chain to produce other products. The system involves three types of inventory stocks,i.e., product 1, 2, and returned inventory. The objective of this research is to minimize total cost per unit time for two types of systems, one in which products of both the supply chains deteriorate and the second in which the products of the first supply chain deteriorate. Kuhn−Tucker method is employed to solve the model and a solution algorithm is proposed to obtain optimal solution. Application of the model is supported with numerical examples and sensitivity analysis. Some managerial insights are provided to help managers while applying the proposed models in real situations. Results of numerical experiments suggest for deteriorating products to plan short replenishment cycles of inventory.
New concept of connection in bidirected graphs
Authors: Bessouf Ouahiba , Khelladi Abdelkader
Published: June 2017

In bidirected graph an edge has a direction at each end. We introduce a new definition of connection in a bidirected graph. We prove some properties of this definition and we establish a relationship to connection and imbalance in the corresponding signed graph. The main result gives a sufficient condition for a signed graph to have a Biconnected biorientation.

Physiotherapeuten sind Praktiker. Doch jedes Handwerk braucht eine theoretische Grundlage. Und die Praxis muss immer wieder auf wirksame und kostengünstige Therapien überprüft werden. Da Physiotherapeuten die Ausführung und Erfolge ihrer Therapien am besten kennen, sollten sie es sein, die die Grundlage für die Physiotherapie schaffen. Dies tut zum Beispiel eine Forschungseinheit am UniversitätsSpital in Zürich. Für physiopraxis haben sich die dort tätigen Physiotherapeuten über die Schulter blicken lassen.
