Adaptive droop control for accurate power sharing in islanded microgrid using virtual impedance

In this paper, the relationship between real and reactive power sharing in islanded microgrid considering the complex impedance effect is analyzed. It is determined that traditional droop control has drawbacks in achieving accurate power sharing caused by the mismatched feeder line effect. In order to enhance the power sharing accuracy, an adaptive droop control using virtual impedance for islanded microgrid is proposed. The method utilizes real and reactive power mismatch, which fed to integral controllers, and then generates the virtual inductive and resistive components. Furthermore, the virtual impedance loop is added to the drooping equation to decouple real and reactive power functions. This proposed method has the advantage of enhancing the load power sharing accuracy among distributed generations (DGs) without requiring knowledge of the line impedances. This is more adaptive to complex impedance situations. The simulation results show the feasibility and correctness of the proposed strategy.
The maintenance of specific aspects of neuronal function and behavior is dependent on programmed cell death of adult‐generated neurons in the dentate gyrus

A considerable number of new neurons are generated daily in the dentate gyrus (DG) of the adult hippocampus, but only a subset of these survive, as many adult‐generated neurons undergo programmed cell death (PCD). However, the significance of PCD in the adult brain for the functionality of DG circuits is not known. Here, we examined the electrophysiological and behavioral characteristics of Bax‐knockout (Bax‐KO) mice in which PCD of post‐mitotic neurons is prevented. The continuous increase in DG cell numbers in Bax‐KO mice resulted in the readjustment of afferent and efferent synaptic connections, represented by age‐dependent reductions in the dendritic arborization of DG neurons and in the synaptic contact ratio of mossy fibers with CA3 dendritic spines. These neuroanatomical changes were associated with reductions in synaptic transmission and reduced performance in a contextual fear memory task in 6‐month‐old Bax‐KO mice. These results suggest that the elimination of excess DG neurons via Bax‐dependent PCD in the adult brain is required for the normal organization and function of the hippocampus.
Indian Boarding School Experience, Substance Use, and Mental Health among Urban Two-Spirit American Indian/Alaska Natives

Background: Systematic efforts of assimilation removed many Native children from their tribal communities and placed in non-Indian-run residential schools. Objectives: To explore substance use and mental health concerns among a community-based sample of 447 urban two-spirit American Indian/Alaska Native adults who had attended boarding school as children and/or who were raised by someone who attended boarding school. Method: Eighty-two respondents who had attended Indian boarding school as children were compared to respondents with no history of boarding school with respect to mental health and substance use. Results: Former boarding school attendees reported higher rates of current illicit drug use and living with alcohol use disorder, and were significantly more likely to have attempted suicide and experienced suicidal thoughts in their lifetime compared to non-attendees. About 39% of the sample had been raised by someone who attended boarding school. People raised by boarding school attendees were significantly more likely to have a general anxiety disorder, experience posttraumatic stress disorder symptoms, and have suicidal thoughts in their lifetime compared to others.
Reduced Dimensional Representations of Molecular Structure

Two-dimensional representations of molecular structure may be generated from the three-dimensional coordinates by nonlinear mapping. These representations not only retain the look of familiar structural formulas but also incorporate the distance geometry information available in three-dimensional structures. The technique is shown to be trivial so long as the molecular structure is not essentially spherical and an objective test as to whether this is true is introduced, together with extensions for coping with such cases. The two-dimensional diagrams have great promise in handling molecular similarity and data searching with very large numbers of compounds since they permit the use of two-dimensional pattern recognition techniques.
A Closed-Form Quantum “Dark Space” Model for Predicting the Electrostatic Integrity of Germanium MOSFETs With High-$k$ Gate Dielectric

This paper provides a closed-form model of the “dark space (DS)” for Ge MOSFETs with high- k gate dielectrics. This model shows accurate dependences on barrier height, surface electric field, and quantization effective mass of the channel and gate dielectric. Our model predicts that the surface DS due to quantum confinement decreases with reverse substrate bias and increasing channel doping. Our model can be also used for devices with a steep retrograde doping profile. This physically accurate model will be crucial to the prediction of the subthreshold swing and electrostatic integrity of advanced Ge devices.
The 46-kDa mannose 6-phosphate receptor does not depend on endosomal acidification for delivery of hydrolases to lysosomes

In mammalian cells, the mannose 6-phosphate receptor pathway accounts for the transport of most soluble acid hydrolases to lysosomes. It is believed that dissociation of mannose 6-phosphate receptors and their ligands is entirely driven by the acidic environment in endosomal compartments. Indeed, pH-perturbing substances such as ammonium chloride and monensin have been shown to inhibit lysosomal enzyme targeting in cells that express both known mannose 6-phosphate receptors. We now demonstrate that ammonium chloride and monensin exert modest effects on the intracellular retention of lysosomal hydrolases in murine cells that synthesize only the 46-kDa mannose 6-phosphate receptor. Neither ammonium chloride nor monensin induces changes to the subcellular localization of lysosomal hydrolases and the 46-kDa mannose 6-phosphate receptor in these cells. This suggests that endosomal dissociation of the receptor and its ligands still occurs in the presence of these agents. We conclude that the murine 46-kDa mannose 6-phosphate receptor has the capacity to deliver its cargo proteins to lysosomes even in the absence of endosomal acidification.
Application of multi-branch neural networks to stock market prediction

Recently, artificial neural networks (ANNs) have been utilized for financial market applications. On the other hand, we have so far shown that multi-branch neural networks (MBNNs) could have higher representation and generalization ability than conventional NNs. In this paper, we investigate the accuracy of prediction of TOPIX (Tokyo stock exchange prices indexes) using MBNNs. Using the TOPIX related values in time series and other information, MBNNs can learn the characteristics of time series and predict the TOPIX values of the next day. Several simulations were carried out in order to compare the proposed predictor using MBNNs with that using conventional NNs. The results show that the proposed method can have higher accuracy of the prediction.
CFO of the Future: Strategic Contributor or Value Adder?

The traditional image of a CFO is one of glorified "bean counter", whose primary responsibility is to prepare the books and report back to higher level management on the overall financial risk and performance of the enterprise. However, rapid globalization of Australian business, the impact of information technologies, changing business and organizational structures, the growing importance of strategic alliances, and a new focus on value creation has challenged this traditional role of the CFO. The importance of the CFO in performing a more integrated and proactive ‘strategic’ and ‘value creation’ role pervades the professional literature. This study reports the results of an attitudinal survey of 241 CFOs drawn from the private and public sectors. The survey findings indicate that whilst CFOs still rate traditional aspects of their role and function quite highly, however value creation and strategic activities and priorities are gaining ascendance. Further, the results show that the value creating activities of CFOs are more directly related to overall strategy contributions within the organization than with direct measures of organizational performance, such as EPS and ROA. The study contributes to a greater understanding of the desired skill sets, knowledge and professional responsibilities of tomorrow’s accountants.
Application of Linear Classifier on Chinese Spam Filtering

is a key problem in electronic communication. Especially in large-scale email systems. Content-based filtering is one mainstream method of combating this threat in its forms, an e-mail filtering system can learn directly from a user’s mail set, but the previous Content-based filtering methods are hard to find a balance between efficiency and effectiveness. Such algorithms of text categorization as Naive Bayes, kNN, Decision Tree and Boosting can be applied in spam filtering. However, the effectiveness of Naive Bayes is limited and it is not fit for instant feedback learning. Others algorithm such as SVM are more effective but complicated to compute. Because in a real email system a large volume of emails often need to be handled in a short time, efficiency will often be as important as effectiveness when implementing an anti-spam filtering method. So we intend to find a linear classifier to solve this problem, two online linear classifiers: the Perception and Winnow were explored for this task, which are two fast linear classifiers. The training of these two methods is online and mistake driven. Furthermore, they are suitable for feedback. We employ the two methods in three benchmark corpora, including PU1, Ling spam and 2005-Jun, the experiments in public e-mail corpus show an effective result. We conclude that the two online linear classifiers have a state-of-the-art performance for filtering spam, especially for Chinese spam emails.

Riders can be asked to follow prescribed trajectories while having diverse visual and haptic cues. This experiment setup can help understand the synergy among the parts intervening in the active stabilizing process in bicycling. Discussion and conclusions are parts of this paper. Keywords: bicycle, simulator, dynamics, haptic feedback, real time
Estimating the Structure of Capacity Utilization in the Fishing Industry

Research in industrial market structure has usually included capacity utilization behavior as a measure of market performance. Traditionally, this capacity has been used to gauge an industry's ability to absorb increased production without adding fixed resources. This includes, for example, some extraordinary situations such as World War II, or, as in fisheries, the extension of the U.S. coastal economic jurisdiction to 200 miles. Recently, however, there has been much research that has both expanded the definition of capacity behavior and improved the accuracy of analytical techniques. It has thus become possible to apply a capacity analysis in an expanded framework and to look at certain types of industry behavior that have been relatively neglected. This paper discusses a consistent methodology for estimating the capacity utilization structure of an industry at various stages of processing. The empirical examples deal with the canned tuna and shrimp industries. These were chosen because they met two requirements: I) Both have a volatile natural resource to harvest, and 2) both have a large and relatively stable processing sector. Relating to the first point above, a major problem in analyzing an industry dependent upon the harvest of a scarce natural resource is that the output of the industry may not be directly related to the inputs of producing factors.

A core region of the mafK gene IN promoter directs neurone‐specific transcription in vivo

MafK serves as a required subunit of erythroid transcription factor NF‐E2 and also functions with various heterodimeric CNC family proteins. MafK expression begins in early mesoderm and is observed in mesenchymal and haematopoietic cells, as well as in neurones during mouse development. In mesodermal descendants, MafK mRNA begins with a distal first exon (called IM), whereas the mRNA in neurones begins with a proximal first exon (IN).
Understanding Entrepreneurship in Traditional Media

Abstract The phenomenon of media entrepreneurship is currently attracting increasing interest by scholars and practitioners alike. However, most of this attention is devoted to entrepreneurship within new media, while some of the traditional media industries—for example print media—are believed to be the living dead without much future promise. Nonetheless, sustainable entrepreneurial ventures do emerge in these traditional media industries. These ventures demonstrate that new venture creation and survival in traditional media industries is in fact possible and that the current scholarly focus on new media entrepreneurial activities is too restrictive. This article conceptualizes and explores the phenomenon of entrepreneurship in traditional media industries. Empirically, it is based on the Swedish case of the company Latifeh, its magazine Gringo, and their further (media) activities. Gringo and the team behind it have received massive media attention as well as several prizes for their innovativeness, and stirred up the emotions of many people. A number of propositions are derived from the case, which can serve as a starting point of future empirical work on media entrepreneurship in traditional industries. In addition, these propositions can serve as practical guiding lights for (potential) media entrepreneurs.
Practical landmarks for visual field disability in glaucoma

Background/Aims To assess whether mean deviation (MD) from automated perimetry is related to the visual field (VF) component for legal fitness to drive (LFTD) in glaucoma patients. Methods Monocular 24-2 VFs of 2604 patients with bilateral VF damage were retrospectively investigated. Integrated visual fields were calculated and used as a surrogate to assess LFTD according to current UK driving licence criteria. The better eye MD (BEMD), worse eye MD (WEMD) and a measure utilising MD of both eyes were compared, to assess respective diagnostic capabilities to predict LFTD (using the integrated visual field surrogate test as the gold standard) and a ‘Probability of Failure’ (PoF) for various defect levels was calculated. Results BEMD appears to be a good predictor of the VF component for a patient's LFTD (receiver operating characteristic area under the curve: 96.2%); MDs from both eyes offered no significant extra diagnostic power (area under the curve: 96.4%). PoF for BEMD thresholds of ≤−10 dB and ≤−14 dB were 70 (95% CI 66% to 74%) and 92% (87% to 95%), respectively. Conclusion There is a strong relationship between BEMD and a patient's LFTD. PoF values for LFTD associated with readily available MD values provide practical landmarks for VF disability in glaucoma.
The assessment of methods for determination of company’s solvency

There are many methods for assessment of the solvency of companies. One method of the financial analysis is calculation of the financial coefficient and determination of the relationship between the indicators, which is used in the assessment of the solvency of enterprises and in the forecasting of insolvency and bankruptcy. To examine the suitability of offered methodologies for determining solvency to conditions in Latvia, the author conducted a theoretical research and a practical study on methods for determining the solvency, by using data from financial statements from small enterprises in Latvia. The aim of the research is to assess the methods for determining the solvency of enterprises. The result of the research shows that different methods of assessing the solvency of the company give different results, that the data from financial statements do not give complete and objective assessment of the company solvency, and it is not possible to forecast the financial stability of the company by using only financial indicators.

Findings – ANOVA results indicated that .
Everyday Simplicity: The Implications of Everyday Tasks for Ubiquitous Computing Applications

Abstract In Mark Weiser’s original 1991 vision, Ubiquitous Computing was defined as invisible computers in different sizes, situated to specific tasks: “People will simply use them unconsciously to accomplish everyday tasks. ” An analysis on everyday tasks is needed in order to determine options for Ubicomp applications to be developed on a broad level. Everyday activities must be done quickly and often simultaneously with other activities. The structure of everyday activities minimizes planning and mental computation. An everyday task must have few choices at any point, which requires little planning - or as Norman (1989) put it: “Everyday activities are conceptually simple”. The simplicity of everyday tasks provides good opportunities to bring the Ubicomp vision to life. This paper follows the approach of the early Ubicomp intentions to focus on everyday tasks and what determines the specification of information system applications in that case. Moreover we outline the importance of intermediate solutions for end-users to experience and accept Ubicomp technologies. Finally we describe the evaluation of a grassroots case study of an artifact that shows the main aspect of everyday tasks: simplicity and the setup of an instant Ubicomp application with available components.
Guanxi and distribution in China: the case of Ferrero Group

This paper aims to analyze how guanxi-based business relations impact on distribution choices of foreign companies entering China. In particular, it investigates the influence of guanxi on decisions regarding both the organization of distribution channels and the management of distribution channels. It emerges that from an organizational point of view guanxi-based business relations may favor interdependence, low integration in the channel relationships, and foster multichannel choices. From a management point of view, guanxi may reduce the control of local partners over channel, create coexistence between conflict and collaboration in the channels relationships, and favor unmediated communication. The authors examine the emblematic case of Ferrero, a well-known Italian multinational company, specialized in chocolate production, which began to develop its entry strategy in China more than 30 years ago.

It makes full use of the searchable encryption and trusted computing technology. Given the performance limit of the mobile devices, it proposes the trusted proxy based protection architecture. The design basic idea, deploy model and key flows are detailed. The analysis from the security and performance shows the advantage.
Electron emission and image-charge acceleration for the impact of very highly charged ions on clean gold.

We present total yields for emission of slow (${\mathit{E}}_{\mathit{e}}$\ensuremath{\le}50 eV) electrons due to the impact of slow (${\mathit{v}}_{\mathit{p}}$\ensuremath{\le}5\ifmmode\times\else\texttimes\fi{}${10}^{5}$ m/s) highly charged ions [${\mathrm{Ar}}^{\mathit{q}+}$ (q\ensuremath{\le}18), ${\mathrm{Xe}}^{\mathit{q}+}$ (q\ensuremath{\le}51), and ${\mathrm{Th}}^{\mathit{q}+}$ (q\ensuremath{\le}80)] on clean polycrystalline gold. The highly charged ions were produced in the Lawrence Livermore National Laboratory electron-beam ion trap; electron yields have been derived from the respective measured electron emission statistics. The experimental data support a currently accepted scenario for multicharged ion-induced electron emission, which is largely based on a classical over-barrier model. In particular, we are able to distinguish different processes contributing to the total above-surface electron emission. In addition, an ultimate low-impact-energy limit due to projectile self-acceleration toward the metal surface, as a result of the projectile image charge, has been demonstrated and evaluated.
Biosensor for the Detection of Specific DNA Sequences by Impedance Spectroscopy

In the agro-food industry there is a great need for rapid, sensitive and label-free biosensors for food quality control, for example the detection of pathogenic agents such as listeria or salmonella in dairy food samples. We are currently working on the development of a real-time monitoring system based on an interdigitated electrode DNA biochip for the detection of specific DNA target sequences. The biosensor contains four active areas on which DNA probes of various kinds can be immobilized, and is integrated into a microfluidic system. Impedimetric measurements of matching and non-matching synthetic target DNA sequences have been performed.
Maintaining verification test consistency between executable specifications and embedded software in a virtual system integration laboratory environment

The root causes of the majority of software defects discovered during the integration test phase of an embedded system development project have been attributed to errors in understanding and implementing requirements. The independence that typically exits between the system and software development processes provides ample opportunity for the introduction of these types of faults. This paper shows a viable method of verifying object software using the same tests created to verify an executable specification-based system design from which the software is developed. If the object software passes the same tests used to verify the system design, it can be said that the software has correctly implemented all of the known system requirements. This method enables the discovery of functional faults prior to the system integration test phase of a project. Previous research has shown that finding software faults early in the development cycle not only improves software assurance, but also reduces software development expense and time.
