A Concept of Distributed Energy Management Systems with Fully Decentralized Primary Control Strategies for Microgrids

Due to environmental and economic incentives the penetration of distributed energy resources (DERs) is increasing worldwide. The concept microgrid (MG) is expected as a promising solution to deal with the huge amount of DERs. A MG contains usually interconnected loads, storages and DERs, which can operate both in grid-connected (GC) and islanded mode. In this thesis a control concept for MGs in both GC and islanded mode is presented. This control concept consists of a distributed energy management system (EMS) and a fully decentralized primary control system. The distributed EMS is based on a price-based model predictive control approach, where a so-called market-maker (MM) is introduced to coordinate the electricity consumers, resources and storages within a MG. The decisions on consumption, production and charging strategy are distributed to each electricity end-user, whereas the MM gathers the power demand from each end-user and initiates a negotiation process if the network requirements or the power balance would be violated. The electricity price would converge to a new point/sequence depending on the network conditions and a compromise for all parties would be found. The decentralized primary control system is designed based on the H-infinity-optimal control approach. To that purpose a network model with quick dynamics is set up. The H-infinity-norm of the performance channels mapping from the disturbances to the predefined performance outputs is minimized by tuning the control parameters collectively. Especially in islanded mode, the droop control law for inverters with a first-order low-pass filter has been interpreted as a mimic of classical synchronous generator dynamics with inertia. By tuning the virtual inertias of inverters a better performance can be achieved.
Role of Pattern Recognition Receptors in the Modulation of Antimicrobial Peptide Expression in the Corneal Epithelial Innate Response to F. solani

Purpose Fusarium solani (F. solani) keratitis is a potentially sight-threatening fungal infection of the cornea. Antimicrobial peptides (AMPs), such as human β-defensins (hBDs) and cathelicidins, essential components of the immune system, likely have a protective role against F. solani keratitis. We examined the role of pattern recognition receptors (PRRs), Dectin-1, and TLR2 in F. solani–induced modulation of AMP expression in vitro. Methods Human corneal epithelial cells (HCECs) were exposed to heat-inactivated F. solani or pathogen-associated molecular patterns (PAMPs) of F. solani (Zymosan or Zymosan Depleted) for 6, 12, or 24 hours following which AMP mRNA and protein levels were determined. Involvement of TLR2 and Dectin-1 was confirmed by using siRNA knock-down (TLR2 and Dectin-1) or chemical inhibitor BAY 61-3606 (Dectin-1). The functional significance of AMP upregulation was tested using culture supernatant from F. solani or PAMP-treated HCECs against F. solani in the presence of hBD2 or LL37 neutralizing antibody. Results We confirm that HCECs express Dectin-1 and TLR2. HCECs demonstrated upregulation of AMPs hBD2 and cathelicidin LL37 following exposure to heat-inactivated F. solani or PAMPs. TLR2 and Dectin-1 knockdown and BAY 61-3606 treatment decreased AMP mRNA upregulation confirming PRR involvement. The culture supernatant from F. solani or PAMP-treated HCECs showed substantial killing of F. solani and hBD2 or LL37 neutralizing antibody significantly decreased this effect implicating involvement of these AMPs. Conclusions These findings demonstrate that Dectin-1 and TLR2 have an important role in regulating F. solani-induced AMP expression in corneal epithelial cells.
Relationships of Palearctic and Nearctic ‘glacial relict’Myoxocephalus sculpins from mitochondrial DNA data

The relationships among Myoxocephalus quadricornis complex fish from Arctic coastal waters and from ‘glacial relict’ populations in Nearctic and Palearctic postglacial lakes were assessed using mtDNA sequence data (1978 bp). A principal phylogeographical split separated the North American continental deepwater sculpin (M. q. thompsonii) from a lineage of the Arctic marine and North European landlocked populations of the fourhorn sculpin (M. q. quadricornis). The North American continental invasion took place several glaciation cycles ago in the Early‐to‐Middle Pleistocene (0.9% sequence divergence); the divergence of the European and Arctic populations was somewhat later (0.5% divergence). The Nearctic‐Palearctic freshwater vicariance in Myoxocephalus, however, appears clearly younger than in similarly distributed ‘glacial relict’ crustacean taxa; the phylogeographical structure is more similar to that in other northern Holarctic freshwater fish complexes.
A framework of significant human resource management practices in Vietnam

Oct. 25, 2017 This paper aims at conceptualizing a framework of human resource management practices (HRMPs) that will work effectively in Vietnam. qualitative research is applied, based on a survey of 388 companies located in Ho Chi Minh city, Vietnam. HRMPs in Vietnam can be measured using seven criteria. Apart from the four traditional HRM functions, which are recruitment selection, training development, performance appraisal and compensation, HRMPs in the Vietnamese context involve three additional criteria: leading change and motivation, both based on traditional soft practices, and talent management, which is based on contemporary hard practice. The validity and reliability of the HRMPs has been confirmed. It was found that the role of HRMPs explains 43 per cent of the variation in a firm’s business performance. The findings imply that HRMPs in Vietnam, despite lagging behind global trends, are on track to catch up with them. The trend of adopting HRMPs in Vietnam continues with the emergence of traditional HRM soft practices and contemporary HRM hard practices. The typical framework of most common HRMPs in Vietnam implies that there is a need to design appropriate training programs for both HR professionals and line managers.
Morphogénése et variabilité au sein du système oculo-moteur

Un vaste corpus de recherches computationnelles est consacre a l’analyse du controle moteur. Cette approche, qui etudie l’adaptation saccadique comme un modele d’apprentissage sensori-Moteur, invoque des mecanismes specialises dans la calibration de gains internes ou l’optimisation de fonctions de couts. Cette these propose une explication differente de l’apprentissage oculo-Moteur en montrant que les distributions d’amplitudes saccadiques peuventetre modifiees par leurs consequences.D’abord, nous avons manipule la mediane du gain saccadique. Nous avons elimine l’erreur retinienne post-Saccadique et presente des stimulus sonores ou visuels apres les saccades repondant a des criteres d’amplitude. Ce renforcement operant a induit des changements de gain similaires a l’adaptation saccadique obtenue par le paradigme conventionnel de double saut. Puis nous avons montre qu’une part de la variabilite peut etre controlee par un apprentissage operant. Differents niveaux de variabilite de gain ont ete renforces avec un son. Les changements obtenus suggerent que la variabilite ne resulte pas uniquement d’un bruit interne. Enfin, dans une tâche de recherche visuelle, la presentation de la cible en guise d’agent renforcateur a aussi permis d’augmenter puis de reduire la variabilite des amplitudes saccadiques. Cela signifie que voir lacible est une consequence qui controle (en partie) les proprietes des saccades.Ces etudes montrent qu’un processus general d’apprentissage, qui depend des consequences fonctionnelles des saccades, peut guider les changements de leur amplitude. Cela pourrait s’averer crucial pour maintenir la precision des saccades tout au long de la vie.
A Dynamic Resource Prices among Cloud Providers

The cloud exhibit is nowadays furiously competitive with many cloud suppliers. On one hand, cloud suppliers move up in opposition to each other for both current and new cloud customers. To maintain current clients and pull in rookies, it is pivotal for every provider to offer a great value strategy which augments the final earnings and enhances the top hand. The opposition amongst providers prompts the advancement of the marketplace and dynamic asset fees more minutes. Then once more, cloud suppliers may also collaborate with each different to beautify their last profits. In view of a Service Level Agreement, a dealer can outsource its clients' asset solicitations to its associate to decrease the operation cost and along those lines beautify the closing profits. This prompts the problem of deciding the collaborating parties in an agreeable situation. [1]This paper handles those two issues of the present cloud put it on the market. To start with, we take care of the difficulty of contention amongst providers and recommend a dynamic price association. We make use of a discrete selection version to depict the consumer's choice behavior in view of his received advantage esteem. The choice show is utilized to determine the likelihood of a purchaser being served with the aid of a selected provider. The opposition amongst suppliers is detailed as a non-helpful stochastic diversion wherein the gamers are suppliers who act via presenting the price strategy on the equal time. The diversion is proven as a Markov Decision Process whose association is a Markov Perfect Equilibrium. At that point, we address the collaboration among providers through displaying a novel calculation for finding out a participation approach that advises providers whether or not to fulfill customers' asset asks for domestically or outsource them to a selected supplier. The calculation yields the correct collaboration shape from which no provider singularly goes off beam to gather income. Numerical reenactments are carried out to assess the execution of the proposed fashions.

Alterations in the Proliferating Compartment of Gastric Mucosa during Helicobacter Pylori Infection: The Putative Role of Epithelial Cells Expressing p27kip1

The proliferating zone contains stem cells that give rise to all epithelial cells of the gastric mucosa. In the present study, we investigated the turnover of gastric epithelial cells in the proliferating zone of Helicobacter pylori–infected mucosa, with or without intestinal metaplasia, before and after eradication of the microorganism. In addition, we studied the topographical distribution of the cyclin dependent kinase inhibitor p27Kip1, which plays a critical role in cell cycle progression and differentiation programs. Twenty-eight patients (22 male), aged 32–78 years and with dyspeptic symptoms, were endoscoped, and gastric biopsies were obtained from antrum and corpus for histopathological examination and the Campylobacter-like organisms test; eradication therapy was given to infected patients, and all patients were re-endoscoped after 105 ± 33 days (mean ± SD). The kinetics of gastric epithelial cells and p27Kip1 status was assessed by means of immunohistochemistry and TUNEL (Tdt-mediated dUTP-biotin nick end labeling) assay. Twenty-one (21) of 28 patients were H. pylori positive, and 7 were found H. pylori negative and served as controls. In antrum, intestinal metaplasia was detected in 7/21 (33.3%). In H. pylori gastritis, Ki67 expression was found increased in the proliferating zone, compared with normal (P = .03); analogous results were obtained with the other proliferation markers, namely retinoblastoma protein and topoisomerase IIα. An inverse relationship between proliferation index and atrophy was disclosed (P = .02). A reduction in the proliferation index was observed after eradication, albeit not significant. Apoptotic epithelial cells were found significantly increased (P < .01) in H. pylori gastritis, and a significant reduction was observed after eradication (P < .01). In addition, apoptotic index was found to correlate with H. pylori density. The topographical study of p27Kip1 revealed a p27kip1-positive epithelial cell population that resided deep in the proliferating zone; these cells were considered to be stem cells and were found significantly increased in areas with intestinal metaplasia (P < .05); in H. pylori gastritis, there was also an increase that did not reach statistical significance. H. pylori infection induces apoptosis and increases proliferation in the proliferating zone. The increased cellular turnover, together with the increased number of putative p27Kip1-positive stem cells in the context of intestinal metaplasia, provides further evidence for the role of H. pylori infection in gastric carcinogenesis.
Exercise Paradigms to Study Brain Injury Recovery in Rodents

Exercise has been found to influence molecular systems important for maintaining neural function and plasticity as well as treatment of neurologic disorders. The stimuli required to elicit plasticity are thought to be activity dependent. Several protocols of physical exercise have been used to explore its effects on brain function. However, it is becoming increasingly recognized that no single physical exercise model is likely to fulfill all therapeutic needs. Varied interpretations of data derived from animal models have given rise to the lack of uniformity in the description and control of various features of the physical exercise stimulus, ranging from low to high intensity, intermittent to sustained, short to long durations, and different modes of activity. This article first describes the characteristics of the most frequently used animal models and goes on to review brain plasticity in intact animals and the usefulness of these models for the study of brain disorders. In this regard, animal models that investigate the beneficial effects of exercise on the brain before and after brain injury are discussed. A challenge for future studies is to better evaluate the usefulness of physical exercise protocols for preventing or treating brain disorders.
An impedance modulated class-E polar amplifier in 90 nm CMOS

This paper presents a digital amplitude modulator for a polar transmitter. The instantaneous output power is modulated by adjusting the amplifier's load through a digitally controlled impedance transformation network. The modulator is suited for modulation schemes with moderate peak-to-average power ratio (PAPR), such as π/4 DQPSK The modulator may also be used for fine gain control in constant envelope modulation schemes. A class E amplifier with digital impedance amplitude modulation is integrated in 90nm CMOS. It achieves a peak output power of 9dBm with a PAE of 30% when powered from a 1.2V supply. The measured EVM is 2.6% for a 6dBm π /4 DQPSK modulated signal with 2Mb/s signal rate at 2.4GHz RF frequency.
Bag-of-Visual-Words Scene Classifier With Local and Global Features for High Spatial Resolution Remote Sensing Imagery

Scene classification has been studied to allow us to semantically interpret high spatial resolution (HSR) remote sensing imagery. The bag-of-visual-words (BOVW) model is an effective method for HSR image scene classification. However, the traditional BOVW model only captures the local patterns of images by utilizing local features. In this letter, a local-global feature bag-of-visual-words scene classifier (LGFBOVW) is proposed for HSR imagery. In LGFBOVW, the shape-based invariant texture index is designed as the global texture feature, the mean and standard deviation values are employed as the local spectral feature, and the dense scale-invariant feature transform (SIFT) feature is employed as the structural feature. The LGFBOVW can effectively combine the local and global features by an appropriate feature fusion strategy at histogram level. Experimental results on UC Merced and Google data sets of SIRI-WHU demonstrate that the proposed method outperforms the state-of-the-art scene classification methods for HSR imagery.
Cancer Mortality through 2005 among a Pooled Cohort of U.S. Nuclear Workers Exposed to External Ionizing Radiation

Nuclear workers worldwide have been studied for decades to estimate associations between their exposure to ionizing radiation and cancer. The low-level exposure of these workers requires pooling of large cohorts studied over many years to obtain risk estimates with appropriate latency and good precision. We assembled a pooled cohort of 119,195 U.S. nuclear workers at four Department of Energy nuclear weapons facilities (Hanford site, Idaho National Laboratory, Oak Ridge National Laboratory and Savannah River site) and at the Portsmouth Naval Shipyard. The cohort was followed at the start of the workers beginning their radiation work (at earliest, between 1944 and 1952) through 2005, and we compared its mortality to that of the U.S. population. We also conducted regression-modeling analysis to evaluate dose-response associations for external radiation exposure and outcomes: all cancers, smoking- and nonsmoking-related cancers, all lymphatic and hematopoietic cancers, leukemia (excluding chronic lymphocytic), multiple myeloma, cardiovascular disease and others. The mean dose observed among the cohort was 20 mSv. For most outcomes, mortality was below expectation compared to the general population, but mesothelioma and pleura cancers were highly elevated. We found an excess relative risk (ERR) per 10 mSv of 0.14% [95% confidence interval (CI): −0.17%, 0.48%] for all cancers excluding leukemia. Estimates were higher for nonsmoking-related cancers (0.70%, 95% CI: 0.058%, 1.5%) and lower for smoking-related cancers (−0.079%, 95% CI: −0.43%, 0.32%). The ERR per 10 mSv was 1.7% (95% CI: −0.22%, 4.7%) for leukemia, which was similar to the estimate of 1.8% (95% CI: 0.027%, 4.4%) for all lymphatic and hematopoietic cancers. The ERR per 10 mSv for multiple myeloma was 3.9% (95% CI: 0.60%, 9.5%). The ERR per 10 mSv for cardiovascular disease was 0.026% (−0.25%, 0.32%). Little evidence of heterogeneity was seen by facility, birth cohort or sex for most outcomes. The estimates observed here are similar to those found in previous large pooled nuclear worker studies and also (with the exception of multiple myeloma) to those conducted in the Life Span Study of Japanese atomic bomb survivors. The tendency of observed risks to persist many years after exposure for most outcomes illustrates the importance of continued follow-up of nuclear worker cohorts.
Factors Influencing Tomato Prices at Tennessee Farmers' Markets

The number of farmers’ markets in the United States continue increasing but at a decreasing rate. Additionally, although the number of farms with direct to consumer (DTC) sales, including farmers’ markets sales, increased by about 6% between 2007 and 2012, DTC sales did not change in this same time period. For those vendors still using farmers’ markets as their main marketing channel, a better understanding on how to price their products could influence their likelihood of survival under a more competitive environment. The main purpose of this study is to identify the factors influencing prices at farmers’ markets, particularly Tennessee farmers’ markets prices. Specifically, we evaluated how factors such as weather, location, and consumer characteristics influence tomato prices at Tennessee farmers’ markets. The midrange of weekly per pound tomato prices at Tennessee farmers’ markets between 2013 and 2015, household characteristics, and weather information were used for this analysis. A random effects panel data regression was used to evaluate the factors influencing tomato prices at Tennessee farmers’ markets. Results suggest the factors influencing tomato prices at Tennessee farmers’ markets are potential customers’ age, household income, and seasonality.
Appreciating local variations in standardising health care data collection processes and tools: A case of health management information system in Tanzania

The need for integration of health information systems as realised in the 90s by the developing countries resulted into deliberate standardisation initiatives. Software systems, human resources, procedures, and data collection tools were all subjected to standardisation. This standardisation, however, has been so absolute that the local and permanent variations were not taken into consideration. This study sought to find out how the local variations within the health care provision units can be taken into consideration in the design of health care data collection processes and tools. It employed qualitative, case study design and had 3 data collection techniques: observations, semi‐structured interviews, and documents review. The study found out that success in standardising data collection tools and processes in health care settings can be achieved if standards are put into clusters as it is unrealistic to subject the different health facility types into the same standards. The study proposes 3 clusters of standards. The dispensary cluster which accounts for the majority of all health facilities and the hospital cluster which accounts for all advanced diagnosis and treatment facilities and the third, specialised hospital cluster which accounts for specialised services.
The potential for Cerenkov luminescence imaging of alpha-emitting radionuclides

Targeted α-emitting drugs are promising for cancer therapy, but cannot be effectively imaged by conventional techniques. Cerenkov luminescence imaging (CLI) has previously been shown capable of imaging β+- and β−-emitting radionuclides in vivo and could have the potential to image α-emitters. Cerenkov light production from α-emitters is through Compton scattering and from farther down the decay chain. This causes the Cerenkov production to vary in time and depend on sample geometry, complicating the interpretation of CLI images. We used the simulation toolkit Geant4 to predict the Cerenkov light output from five α-emitting radionuclides that have therapeutic potential: 225Ac, 230U, 213Bi, 212Bi and 212At. We found that 225Ac, 213Bi and 212Bi produced an order of magnitude more Cerenkov light than 18F. However, the light from 225Ac is delayed from the initial decay, possibly decreasing the correlation of the drug and light source. This indicates that CLI will not be helpful in the development of some α-emitting drugs.
