Statistical Cooperative Power Dispatching in Interconnected Microgrids

Load demand management in the context of grid-connected microgrids is the scope of this paper. This issue is formulated as a power dispatching problem between distributed power sources with the objective of grid operational cost minimization. Under the assumption of time-varying demands and supplies at individual microgrids, a cooperative power dispatching algorithm of interactions among microgrids is proposed for power sharing within the grid. This is done through a communication infrastructure in the grid and a set of defined parameters known as purchase prices at individual microgrids. As a result of this algorithm, power flows within the grid are regulated to smooth power generations at microgrids despite the stochastic load demands. Numerical results demonstrate the effectiveness of the proposed load management scheme in comparison with no power sharing scheme in the grid operational cost point of view. Moreover, optimal solution of the power problem verifies these results.
Protein isoprenylation regulates osteogenic differentiation of mesenchymal stem cells: effect of alendronate, and farnesyl and geranylgeranyl transferase inhibitors

BACKGROUND AND PURPOSE Protein isoprenylation is an important step in the intracellular signalling pathway conducting cell growth and differentiation. In bone, protein isoprenylation is required for osteoclast differentiation and activation. However, its role in osteoblast differentiation and function remains unknown. In this study, we assessed the role of protein isoprenylation in osteoblastogenesis in a model of mesenchymal stem cells (MSC) differentiation.
Molecular Electronic Topology and Fragmentation Onset via Charge Partition Methods and Nuclear Fukui Functions: 1,1-Diamino-2,2-dinitroethylene

We investigated theoretically the ground state electronic structure and the onset of molecular fragmentation of 1,1-diamino-2,2-dinitroethylene (FOX-7) using density functional theory. The molecular charge density was analyzed via two partition methods: the distributed multipole analysis (DMA) and the deformed atoms in molecules (DAM). In this framework, the push-pull effect, hydrogen intra-molecular bonding and site acid-base properties of the molecule were discussed. Our analysis indicates that the molecular origin of the low measured impact sensitivity of FOX-7 is due to the magnitude of multipole values of the C-N bonds in the NO2 groups, the delocalized electrons over the central C-C bond and the hydrogen bonds. The onset of FOX-7 decomposition and acid-base properties were examined with the nuclear Fukui functions. The results support nitro to nitrite rearrangement and direct release of a NO2 as a possible initial step in FOX-7 decomposition process. The approach suggested is general and can be especially useful for very large molecules to examine in detail their electronic structure and to guide the search for the decomposition mechanisms.
A Long-Term Learning Algorithm in CBIR Based on Log-Analyzing

Nowadays, the amount of images increase drastically. Content-based image retrieval (CBIR) has been proposed to efficiently manage these images. Traditional CBIR system extracts the low features of image automatically. Because of the difference between human comprehension and machine, the search results provided by CBIR system always can not satisfy the user’s need. So relevance Feedback has been used in Contentbased image retrieval (CBIR) to bridge the semantic gap, which is existing between image low-level features and high-level human perceptions. This paper proposes an extended-judging algorithm to analyze the information which includes both positive relevance and negative relevance. It uses the feedback log data and index table to expand the set of relevant images, and judging images in database by the current feedback record. Results show that compared with the traditional long-term learning method, the retrieval performance can be improved apparently. Keywords-CBIR; Relevance feedback; Log data
Assessing the effect of Thyme and Rosemary as antiaflatoxicosis on fertility in male rats

Thyme and rosemary play a role in hepatoprotectivity and act as antiaflatoxicosis. This study has attempted to investigate effect of subacute dose of aflatoxin AFB1 on fertility in albino rats and possibly to predict any benefits or harms of rosemary and thyme leaves powder. Aflatoxin were detected and extracted from Aspergillus flavus isolated from poultry rations and processed animal feeds. One hundred samples of poultry rations and processed animal feeds (50 of each) were collected from markets at Cairo governorate for investigation of fungal contamination and detection of aflatoxin. The maximum levels of toxin were obtained from A. flavus isolated from processed animal feeds followed by those isolated from poultry rations. Forty eight apparently health male albino rats weighed (150-170 g) were divided randomly into 6 equal groups. Animals of the first group were given healthy commercial pelleted basal diet and kept as a negative control. The animals of groups 2, 4 and 6 were injected intraperitoneal with AFB1, 1.5 mg/kg body weight. Then on the second day the diet of rats were supplemented with 5% commercial thyme leaves powder for groups 3 & 4 and 2.5 % commercial rosemary powder for groups 5&6. The second group was left without any treatment and kept as a positive control. The period of feeding was continued for 28 days. Aflatoxin injected rats showed unexpectedly increase in weight gain comparing to all tested groups, a significant decrease in somatic index of testis, no significant effect on seminal vesicles, prostate gland weights, sperm count and motility between intoxicated rats and controls. Though a significant increase in testosterone and estradiol levels in intoxicated rats compared to the control group, no significant difference in testosterone estradiol ratio T/E2 was observed. A significant decrease in total antioxidant capacity (TAC) and a significant increase in lipid peroxides (LPO) were observed. Thyme leaves powder fed to healthy or aflatoxin injected rats resulted in significant decrease in weight gain and no significant in testis weight. Thyme leaves improved sperm count and motility, no significant difference in testosterone and progesterone levels. Thyme supplemented to the diet of intoxicated rats did not exhibit any improvement in TAC&LPO. Rosemary leaves powder increased the weight gain significantly in comparable to control group, but reverse effect on weight gain occurred in intoxicated rats. No significant effect on testis and prostate gland weights, sperm count and motility either in healthy or intoxicated rats. Rosemary increased testosterone and estradiol levels either in intoxicated rats or not. Rosemary supplemented to the diet of intoxicated rats did not exhibit any improvement in TAC and LPO. It is interesting to report here that the aflatoxicated rats that treated with rosemary and thyme showed a significant diminution the levels of aflatoxin residues in testis, seminal vesicle and prostate gland. Though doses were referenced, more studies, different doses and pure extracts of thyme and rosemary are recommended.
Homogenization of Composite Panels From a Near-Field Magnetic Shielding Effectiveness Measurement

A simple method permitting to obtain a homogeneous panel from a strongly inhomogeneous panel is presented. The method consists of determining the characteristics of a panel having an equivalent conductivity obtained from a near-field magnetic shielding effectiveness measurement. Thus, the method suitable for frequencies lower than 1 MHz does not require the knowledge of the detailed internal geometry of the sample. After the validation of the measurement setup on a copper plate of known conductivity, two space composite panels are characterized and homogenized.
NITRIC OXIDE‐DEPENDENT ENDOTHELIAL FUNCTION IS UNAFFECTED BY ALLOPURINOL IN HYPERCHOLESTEROLAEMIC SUBJECTS

1. Hypercholesterolaemia is associated with abnormal endothelium‐related vasodilator function, possibly due to increased destruction •NO by superoxide anions (•O2–). Oxypurinol, a xanthine oxidase (XO) inhibitor with anti‐oxidant properties and the active metabolite of the commonly used drug allopurinol, reduces •NO quenching in vitro and has been reported to acutely improve endothelial function in hypercholesterolaemic subjects.
Parallel Forms in Estonian Finite State Morphology

Parallel forms are two or more synonymous forms that convey an identical set of morpho-syntactic categories in a paradigm cell of a word. They deserve attention from a theoretical linguistic, as well as from a computational point of view. How do humans know which form to choose, and how should this preference be modelled computationally? The paper gives an overview of parallel forms in Estonian and discusses reasons for surface form variation. A considerable part of the article is dedicated to a simplified, but still technically detailed example of handling parallel plural partitive forms, one of which is more common, and the other a rarer form. An example is used to explicate the proposed method of handling parallel forms in finite state morphology, coupled with considerations of their preferencial choice. The method involves using a combination of two-level rules as a way of controlling the combinatorial explosion of continuation lexicons. The design has been implemented to fully cover the inflectional morphology of Estonian.
Model-order reduction using truncated modal balanced realization

In this paper, a modal reduction approach based on the truncated balanced realization technique is proposed to compute reduced-order system models (ROMs). The method enables efficient computation of Gramian covariance matrices in terms of the system frequency response and can be used for control design. Methods for approximating the high-dimensional system dynamics with a low-dimensional model are examined and compared, and the prediction error of the ROMs is evaluated. The proposed technique is tested on a 46-machine dynamic equivalent of the Mexican interconnected system. The issues of accuracy, applicability, and computational effort are discussed.
Three-dimensional analysis of the child cleft face.

OBJECTIVE This study examined the facial surfaces of cleft children and unaffected children aged 8-11 years with the aim of identifying and assessing differences in their facial surface morphology. The investigation was carried out using an Optical Surface Scanner, an instrument that utilizes laser light to construct and archive a three-dimensional image of the face suitable for linear measurement and direct surface comparisons. DESIGN, SETTING, AND PATIENTS Thirty-nine cleft lip and palate (CLP) patients and 25 unaffected subjects were voluntarily recruited from two southeast England hospitals. A range of linear facial measurements was compared. Three-dimensional differences between the cleft subgroups and the control group were visualized by superimposition of averaged cleft scans over the averaged control group images. RESULTS Statistically significant dimensional differences (p < or = .05) in interocular width, nose base widths, mouth widths, and nose base/mouth width ratios were found between the cleft group and the control group. Qualitative differences over the whole of the face were readily demonstrated between the groups by superimposition. Face width and submandibular area depth differed consistently between the groups, the cleft face appearing narrower with a deeper submandibular area. CONCLUSION Significant differences exist between the facial surface morphology of CLP patients and control subjects.
Urban area remote sensing from L-band PolSAR data using Time-Frequency techniques

This article presents a new approach for the study of urban areas using polarimetric SAR (PolSAR) data. The PolSAR multidimensional information is analyzed using a linear time-frequency (TF) decomposition which permits to describe an urban area polarimetric behavior for different azimuth angles of observation and frequencies of illumination. A TF signal model, adapted to the case of urban areas is proposed and studied using two statistical descriptors related to the signal stationary aspect and coherence in the time-frequency domain. These indicators are shown to provide complementary information, adapted to the case of man made environments. A TF based classification is proposed and applied to fully polarimetric SAR data acquired by the ESAR sensor at L-band. Results demonstrate the efficiency of this method in terms of buildings location retrieval and response characterization.
A PLL based 12GHz LO generator with digital phase control in 90nm CMOS

A 12 GHz PLL with digital output phase control has been implemented in a 90 nm CMOS process. It is intended for LO signal generation in integrated phased array transceivers. Locally placed PLLs eliminate the need of long high frequency LO routing to each transceiver in a phased array circuit. Routing losses are thereby reduced and design of integrated phased array transceivers become more modular. A chip was manufactured, featuring two separate fully integrated PLLs operating at 12 GHz, with a common 1.5 GHz reference. The chip, including pads, measures 1050 × 700 ¿m2. Each PLL consumes 15 mA from a 1.2 V supply, with a typical measured phase noise of -110 dBc/Hz at 1 MHz offset. The phase control range exceeds 360°.
Contribution Diagnostic Performance of Pressure Drop Coefficient in Relation to Fractional Flow Reserve and Coronary Flow Reserve

Objectives and Background. Functional assessment of coronary lesion severity during cardiac catheterization is conducted using diagnostic parameters like fractional flow reserve (FFR; pressure derived) and coronary flow reserve (CFR; flow derived). However, the complex hemodynamics of stenosis might not be sufficiently explained by either pressure or flow alone, particularly in the case of intermediate stenosis. CDP (ratio of pressure drop across a stenosis to distal dynamic pressure), a non-dimensional index derived from fundamental fluid dynamic principles based on a combination of intracoronary pressure and flow, may improve the functional assessment of coronary lesion severity. Methods. We performed a meta-analysis of seven studies, retrieved from MEDLINE and PubMed, comparing the results of FFR and CFR of the same lesions. Two studies reported functional measurements (pressure and flow) obtained in individual patients. Five studies reported two-dimensional plots of FFR vs CFR. The FFR and CFR data were digitized and corresponding functional measurements were extracted using the reported mean values of hemodynamic data from each of the five studies. The receiver operating characteristic (ROC) curve was used to identify the optimal cut-off point of CDP, which corresponds to the clinically used cut-off values (FFR = 0.80, FFR = 0.75, and CFR = 2.0). Results. CDP correlated significantly with FFR (r = 0.78; P<.001) and had significant diagnostic efficiency (area under the ROC curve = 89%), specificity (83% and 85%), and sensitivity (81% and 76%) at FFR <0.8 and FFR <0.75, respectively. The corresponding cut-off value for CDP to detect FFR <0.80 and FFR <0.75 was at CDP >27.1 and CDP >27.9, respectively. Conclusions. CDP, a functional parameter based on both intracoronary pressure and flow measurements, has close agreement (area under the ROC curve = 89%) with FFR, the most frequently used method for evaluation of coronary stenosis severity.

Region‐specific alteration of GABAergic markers in the brain of heterozygous reeler mice

Heterozygous reeler mice (HRM), haploinsufficient for reelin, have been proposed to be a genetic mouse model of schizophrenia. Beside behavioural similarities, HRM also demonstrate several neuroanatomical traits similar to patients suffering from schizophrenia. In the present study using immunocytochemical procedures, we investigated HRM and wild‐type mice (WT) for differences in the numbers and densities of glutamic acid decarboxylase (GAD)67 and parvalbumin (PARV)‐immunoreactive (IR) neurons in the hippocampus, tyrosine hydroxylase (TH)‐IR neurons in the ventral tegmental area (VTA) and substantia nigra (SN), and serotonin transporter (5‐HT‐T)‐IR neurons of the raphe nuclei. We found that HRM, compared with WT, show a significant decrease of GAD67‐IR neurons in hippocampal subregion CA1 [stratum pyramidale (SP)], CA2 [stratum oriens (SO), stratum pyramidale (SP) and stratum radiatum (SR)] and dentate gyrus [granule cell layer (GL)], and also a significant decrease of PARV‐containing neurons in CA1 (SO, SP) and CA2 (SP). No morphological differences were found in the SN/VTA or raphe nuclei. In conclusion, these results support a hippocampal γ‐aminobutyric acid (GABA)ergic dysfunction in HRM as previously described by other authors, and may be based on a downregulation of GAD67 and PARV expressions. In summary, the reelin haploinsufficient mouse may provide a useful model for studying the interaction between reelin and hippocampal GABAergic system, its effect on dendritic spine maturation and plasticity related to schizophrenia.
Activity of MS-8209, a nonester amphotericin B derivative, in treatment of experimental systemic mycoses

The in vitro and in vivo toxicities and activities of MS-8209, a new hydrosoluble amphotericin B (deoxycholate-amphotericin B [D-AmB]; Fungizone) derivative, were studied. In vitro, MS-8209 was less toxic than AmB against renal tubular cells in primary culture and less active against Candida albicans and Cryptococcus neoformans. However, at 10-fold the AmB concentration, MS-8209 in vitro antifungal activity paralleled that of AmB. Fifty-percent lethal doses of MS-8209 and D-AmB in OF1 noninfected mice were 26 and 2.3 mg/kg, respectively. Therapeutic efficacy of MS-8209 was assessed in murine candidiasis, cryptococcosis, and aspergillosis. In each model of infection, we determined the maximum tolerated dosages of MS-8209 and D-AmB, i.e., the dosage inducing less than 15% mortality due to toxicity; the efficacies of MS-8209 and D-AmB at their respective maximum tolerated dosages were compared. In candidiasis, MS-8209 (15 mg/kg) significantly increased the survival time compared with D-AmB (0.5 mg/kg). Both compounds were equally effective at reducing CFU counts in the kidney. MS-8209 was the most effective agent for increasing the survival time in cryptococcal meningoencephalitis and for reducing CFU counts in spleen, brain, and lung during both cryptococcal pneumonia and meningoencephalitis. In aspergillosis, MS-8209 and D-AmB similarly prolonged the survival of treated mice compared with controls. These results show that when MS-8209 and D-AmB were used at the maximum tolerated dosage, MS-8209 was as effective as or more effective than D-AmB for the treatment of systemic mycoses. These findings warrant further experiments to study the pharmacokinetic properties and toxicity of MS-8209 under conditions of chronic administration.
Role for a Zinc Finger Protein (Zfp111) in Transformation of 208F Rat Fibroblasts by Jaagsiekte Sheep Retrovirus Envelope Protein

ABSTRACT The native envelope gene (env) of Jaagsiekte sheep retrovirus (JSRV) also acts as an oncogene. To investigate the mechanism of transformation, we performed yeast 2-hybrid screening for cellular proteins that interact with Env. Among several candidates, we identified mouse or rat zinc finger protein 111 (zfp111). The interaction between Env and Zfp111 was confirmed through in vivo coimmunoprecipitation assays. Knockdown of endogenous Zfp111 caused a decrease in cell transformation by JSRV Env, while overexpression of Zfp111 increased overall Env transformation, supporting a role for Zfp111 in Env transformation. Knockdown of Zfp111 had no effect on the growth rate of parental rat 208F cells, while it decreased the proliferation rate of JSRV-transformed 208F cells, suggesting that JSRV-transformed cells became dependent on Zfp111. In addition, Zfp111 preferentially bound to a higher-mobility form of JSRV Env that has not been described previously. The higher-mobility form of Env (P70 env ) was found exclusively in the nuclear fraction, and size of its polypeptide backbone was the same as that of the cytoplasmic Env polyprotein (Pr80 env ). The differences in glycosylation between the two versions of Env were characterized. These results identify a novel cellular protein, Zfp111, that binds to the JSRV Env protein, and this binding plays a role in Env transformation. These results indicate that JSRV transformation also involves proteins and interactions in the nucleus. IMPORTANCE The envelope protein (Env) of Jaagsiekte sheep retrovirus (JSRV) is an oncogene, but its mechanism of cell transformation is still unclear. Here we identified seven candidate cellular proteins that can interact with JSRV Env by yeast two-hybrid screening. This study focused on one of the seven candidates, zinc finger protein 111 (Zfp111). Zfp111 was shown to interact with JSRV Env in cells and to be involved in JSRV transformation. Moreover, coexpression of JSRV Env and Zfp111 led to the identification of a novel nuclear form of the JSRV Env protein that binds Zfp111. Nuclear Env was found to differ by glycosylation from the cytoplasmic Env precursor to the virion envelope proteins. These results suggest that JSRV Env transformation may involve nuclear events such as an alteration in transcription mediated by Env-Zfp111 interactions.
Optimal Policy and Simple Algorithm for a Deteriorated Multi-Item EOQ Problem

In this paper, we explore the optimal policy of this inventory problem by analyzing the structural properties of the model, and introduce a simple algorithm for generating the optimal solution to this problem. Numerical results are reported to show effi-cacy of the proposed method.
Further Research on the Tidal Wave System in the Southern Yellow Sea

A two-dimensional tidal wave model for the Chinese marginal seas with high resolution is set up and the verification results demonstrate that it can well simulate the large domain. Based on this model, a series of numerical experiments are constructed to analyze the influence of local bathymetry and reclamation of the Jiangsu coast on the tidal wave system. According to the simulation results, the existence of the radial tidal current pattern have not been obviously influenced by the local bathymetry except the magnitude of the current velocity. However, it effects the tidal wave near the Jiangsu coast considerably. The reclamation affects the radial current field slightly, whereas the tidal wave near the southern Jiangsu coast is impacted significantly. Besides, further experiments by adding thin dam in the Southern Yellow Sea are studied and discussed. The results illustrate the existence of the tidal wave from the Northern Yellow Sea, which is important for the formation of the rotating tidal wave system in the Southern Yellow Sea.
