Smart Control Strategy for Adaptive Management of Islanded Hybrid Microgrids

This research paper presents a smart power control approach specifically designed for an independent microgrid. The proposed hybrid system consists of various crucial components, including a PV array, super capacitor, DC bus, battery bank, and AC bus working together to generate and store electricity within the microgrid. To address the challenges arising from random fluctuations in ecological parameters and changes in load demand, a supervisory controller is developed to enhance the standalone hybrid microgrid. This allows for optimized power management within the micro grid. The Liebenberg Marquardt algorithm is used to retrieve the trained ANN machine. The two and three hidden layered ANN machines have 96% accuracy on an average, whereas the single-layer ANN machine have poor predictive ability. The proposed model is implemented and analysed using MATLAB/Simulink. The observed results from the simulation experiments validate the effectiveness of integrating available resources in ensuring the resilience and reliability of microgrids.
Distance functions for local PCA methods

The NGPCA method, a combination of the robust neural gas vector quantization method and a fast neural principal component analyzer, has proved to be a valuable tool for the generalized learning of high–dimensional data. At its core, the method uses a competitive ranking to adapt its units. The competition is guided by a specialized distance function — known as the normalized Mahalanobis distance — that assumes elliptic cluster shapes. Recently, an alternative distance function, the normalized Rayleigh quotient, has been suggested. This paper compares the performance of NGPCA on different distance functions. For the comparison a data set from a realistic robot arm experiment is used.
Neural Discrimination of Nonprototypical Chords in Music Experts and Laymen: An MEG Study

At the level of the auditory cortex, musicians discriminate pitch changes more accurately than nonmusicians. However, it is not agreed upon how sound familiarity and musical expertise interact in the formation of pitch-change discrimination skills, that is, whether musicians possess musical pitch discrimination abilities that are generally more accurate than in nonmusicians or, alternatively, whether they may be distinguished from nonmusicians particularly with respect to the discrimination of nonprototypical sounds that do not play a reference role in Western tonal music. To resolve this, we used magnetoencephalography (MEG) to measure the change-related magnetic mismatch response (MMNm) in musicians and nonmusicians to two nonprototypical chords, a “dissonant” chord containing a highly unpleasant interval and a “mistuned” chord including a mistuned pitch, and a minor chord, all inserted in a context of major chords. Major and minor are the most frequently used chords in Western tonal music which both musicians and nonmusicians are most familiar with, whereas the other chords are more rarely encountered in tonal music. The MMNm was stronger in musicians than in nonmusicians in response to the dissonant and mistuned chords, whereas no group difference was found in the MMNm strength to minor chords. Correspondingly, the length of musical training correlated with the MMNm strength for the dissonant and mistuned chords only. Our findings provide evidence for superior automatic discrimination of nonprototypical chords in musicians. Most likely, this results from a highly sophisticated auditory system in musicians allowing a more efficient discrimination of chords deviating from the conventional categories of tonal music.
The pcsA gene is identical to dinD in Escherichia coli

The pcsA68 mutant of Escherichia coli is a cold-sensitive mutant which forms long filaments with a large nucleoid in the central region at 20 degrees C. We here show that (i) the coding region for the pcsA gene is identical with orfY located upstream of pyrE and can be deleted without loss of viability; (ii) pcsA is also identical to dinD, a DNA damage-inducible gene, whose expression is regulated by the LexA-RecA system; (iii) the cold-sensitive phenotype of the pcsA68 mutation is suppressed by delta recA or lexA1 (Ind-) mutation, but not by sulA inactivation; (iv) overproduction of PcsA68 leads to inhibition of cell growth in recA+ and delta recA strains at 20 and 37 degrees C, but PcsA+ does not show such an effect at any temperature; (v) SOS response is induced in the pcsA68 mutant cells at 20 degrees C. We discuss the possible function of the pcsA gene, comparing it with the sulA or the dif-xerCD function. We also describe a new method for gene disruption with positive and negative selection.
HEPATOCELLULAR CARCINOMA : AN OVERVIEW OF CLINICO-PATHOLOGICAL AND MOLECULAR PERSPECTIVES

Hepatocellular carcinoma (HCC) has an increasing incidence worldwide, and it is the leading cause of death in patients with cirrhosis. The criteria for the diagnosis of Hepatocellular carcinoma (HCC) have been defined at the Barcelona2000 EASL (European Association fof the Study of the Liver) conference1. Not so defined were the staging criteria, a useful tool to the physician to choose the most appropriate treatment. Unlike most other cancers, the HCC staging systems pro-
Quantitative Assessment of Retinopathy Using Multi-parameter Image Analysis

A multi-parameter quantification method was implemented to quantify retinal vascular injuries in microscopic images of clinically relevant eye diseases. This method was applied to wholemount retinal trypsin digest images of diabetic Akita/+, and bcl-2 knocked out mice models. Five unique features of retinal vasculature were extracted to monitor early structural changes and retinopathy, as well as quantifying the disease progression. Our approach was validated through simulations of retinal images. Results showed fewer number of cells (P = 5.1205e-05), greater population ratios of endothelial cells to pericytes (PCs) (P = 5.1772e-04; an indicator of PC loss), higher fractal dimension (P = 8.2202e-05), smaller vessel coverage (P = 1.4214e-05), and greater number of acellular capillaries (P = 7.0414e-04) for diabetic retina as compared to normal retina. Quantification using the present method would be helpful in evaluating physiological and pathological retinopathy in a high-throughput and reproducible manner.
Experimentation in Mathematics: Computational Paths to Discovery

New mathematical insights and rigorous results are often gained through extensive experimentation using numerical examples or graphical images and analyzing them. Today computer experiments are an integral part of doing mathematics. This allows for a more systematic approach to conducting and replicating experiments. The authors address the role of experimental research in the statement of new hypotheses and the discovery of new results that chart the road to future developments. Following the lead of Mathematics by Experiment: Plausible Reasoning in the 21st Century this book gives numerous additional case studies of experimental mathematics in action, ranging from sequences, series, products, integrals, Fourier series, zeta functions, partitions, primes and polynomials. Some advanced numerical techniques are also presented. To get a taste of the material presented in both books view the condensed version.

Conservative treatment of primary gastric low-grade B-cell lymphoma of mucosa-associated lymphoid tissue: predictive factors of response and outcome

OBJECTIVES:Primary gastric low-grade B-cell lymphoma of mucosa-associated lymphoid tissue may regress with conservative treatment such as anti-Helicobacter pylori therapy or monochemotherapy. The aims of the present study were to analyze the predictive factors of response to anti-H. pylori treatment, to assess the effects of an adjuvant therapy in responding patients, and to evaluate an alternative therapy in nonresponding patients.METHODS:From 1995 to 2000, 48 H. pylori-infected patients with localized primary gastric low-grade B-cell lymphoma of mucosa-associated lymphoid tissue were treated with anti-H. pylori therapy. Endoscopic and endoscopic ultrasonography features and histological grading of large cells' proportion were analyzed. Eradication of H. pylori and tumoral response were assessed at 2 and 6 months, respectively. From 1996, patients in remission at 6 months were randomized to receive either chlorambucil p.o. for 6 months or no treatment. Patients who did not respond to H. pylori eradication received chlorambucil p.o. for 1 yr.RESULTS:Among the 48 treated patients, 33 (69%) were in complete (n = 28) or in partial (n = 5) remission, and 15 (31%) were in treatment failure at 6 months. H. pylori was eradicated in 47 patients. The response was not correlated with the endoscopic features or with the histological grade. In contrast, it was related to ultrasonographic features: remission was achieved in 76% of patients when no perigastric lymph node was detected versus only 33% when endoscopic ultrasonography showed presence of lymph nodes (p = 0.025). All responding patients remained in remission (median 34 months) whatever the treatment they received (no treatment or chlorambucil). Remission could be achieved with chlorambucil in 58% of the nonresponding patients to anti-H. pylori treatment.CONCLUSIONS:The major negative predictive factor of the tumoral response to anti-H. pylori treatment in patients with primary gastric low-grade B-cell lymphoma of mucosa-associated lymphoid tissue was the presence of perigastric lymph nodes on endoscopic ultrasonography. In responding patients, remission remained stable, suggesting that adjuvant chemotherapy was not useful. In patients who failed to respond to H. pylori eradication, monochemotherapy with chlorambucil proved to be efficient, but new therapeutic modalities should be evaluated to improve the control of the tumoral process.
Block-Ranking: Content Similarity Retrieval Based on Data Partition in Network Storage Environment

Nowadays, data partition plays an important role in eliminating duplicate data in green storage and cloud storage system. Fixed-sized chunking and content based chunking are two kinds of commonly used partition methods to break a file into a sequence of blocks. Meanwhile, inverted index has become the standard indexing method in modern information retrieval field. For conveniently analyzing, the inverted index is represented as inverted matrix and a MapReduce strategy is used to decompose a complex matrix computation into a set of smaller parallelizable sub-matrix computations. In order to efficiently take advantage of the block information to calculate file correlation, we propose a novel Block-Ranking method which utilizes the number of duplicate blocks to weight the correlation among files. The experiment indicates that Block-Ranking algorithm has rapidly enhanced the retrieval efficiency in network storage environment.
High-Quality Single-Domain SmBCO Bulks Prepared by a Sm+011 SIG Technique With New Solid Phase in Air

High-quality single-domain SmBCO bulks have been successfully produced in air by a new Sm+011 SIG method, with a new solid phase of (Sm<sub>2</sub>O<sub>3</sub> + xBaCuO<sub>2</sub>) and a liquid phase of (Y<sub>2</sub>O<sub>3</sub> + 6CuO + 10BaCuO<sub>2</sub>). The onset critical temperature (Tcon) of the SmBCO bulks increases with the increasing of x; the Tcon have reached 96 K when x = 1.4. The amount and the size of Sm211 particles in the samples decreases with the increasing of BaCuO<sub>2</sub> addition x. The levitation force of the samples (φ20 mm) increases from 38.47 to 44.34 N and decreases to 37.94 N with the increasing of x from 0.9 to 1.2 and 1.4. Single-domain SmBCO bulks (φ32 × 8.4 mm) with a levitation force of 98.7 N (77 K, 0.5 T) and a trapped field of 1.15 T (77 K) have been fabricated by the new Sm+011 SIG method. This result provides a very important way to fabricate high-quality single-domain SmBCO bulks in air.
A Novel Approach to Modeling and Flooding in Ad-hoc Wireless Networks

This study proposes a new modeling approach for wireless ad-hoc networks. The new approach is based on the construction of fuzzy neighborhoods and essentially consists of assigning a membership or importance degree to each network radio link which reflects the relative quality of this link. This approach is first used to model the flooding problem and then an algorithm is proposed to solve this problem which is of a great importance in ad-hoc wireless networks intrinsically subject to a certain level of node mobility. Simulations carried out in a dynamic environment show promising results and stability compared to the enhanced dominant pruning algorithm. Such an approach is suitable to take into account the volatile aspect of radio links and the physical layer uncertainty when modeling these networks, particularly when the physical layer offers no or insufficient guaranties to high-level protocols as for the flooding.
Utilizing Performance Unit Tests To Increase Performance Awareness

Many decisions taken during software development impact the resulting application performance. The key decisions whose potential impact is large are usually carefully weighed. In contrast, the same care is not used for many decisions whose individual impact is likely to be small -- simply because the costs would outweigh the benefits. Developer opinion is the common deciding factor for these cases, and our goal is to provide the developer with information that would help form such opinion, thus preventing performance loss due to the accumulated effect of many poor decisions. Our method turns performance unit tests into recipes for generating performance documentation. When the developer selects an interface and workload of interest, relevant performance documentation is generated interactively. This increases performance awareness -- with performance information available alongside standard interface documentation, developers should find it easier to take informed decisions even in situations where expensive performance evaluation is not practical. We demonstrate the method on multiple examples, which show how equipping code with performance unit tests works.
Production of Bioactive Diterpenoids in the Euphorbiaceae Depends on Evolutionarily Conserved Gene Clusters[C][W][OPEN]

The Euphorbiaceae produce a wide range of biologically active diterpenoids. Using castor (Ricinus communis) as a model, this work provides evidence that some of the genes required for the biosynthesis of these diterpenoids are arranged in physical gene clusters and describes a conserved oxidation step required for biosynthesis of a majority of diterpenoids that has been reported in this family. The Euphorbiaceae produce a diverse range of diterpenoids, many of which have pharmacological activities. These diterpenoids include ingenol mebutate, which is licensed for the treatment of a precancerous skin condition (actinic keratosis), and phorbol derivatives such as resiniferatoxin and prostratin, which are undergoing investigation for the treatment of severe pain and HIV, respectively. Despite the interest in these diterpenoids, their biosynthesis is poorly understood at present, with the only characterized step being the conversion of geranylgeranyl pyrophosphate into casbene. Here, we report a physical cluster of diterpenoid biosynthetic genes from castor (Ricinus communis), including casbene synthases and cytochrome P450s from the CYP726A subfamily. CYP726A14, CYP726A17, and CYP726A18 were able to catalyze 5-oxidation of casbene, a conserved oxidation step in the biosynthesis of this family of medicinally important diterpenoids. CYP726A16 catalyzed 7,8-epoxidation of 5-keto-casbene and CYP726A15 catalyzed 5-oxidation of neocembrene. Evidence of similar gene clustering was also found in two other Euphorbiaceae, including Euphorbia peplus, the source organism of ingenol mebutate. These results demonstrate conservation of gene clusters at the higher taxonomic level of the plant family and that this phenomenon could prove useful in further elucidating diterpenoid biosynthetic pathways.
The Development and Validation of Hundred Paisa Pain Scale for Measuring Musculoskeletal Pain

Abstract The reduction in the pain intensity is one of the most important outcome measures in musculoskeletal disorders. The assessment of pain required reliable and valid scale. The aims of this prospective observational study were to develop and evaluate concurrent validity and test–retest reliability of hundred paisa pain scale (HPPS) for measuring musculoskeletal pain. A consecutive 74 patients with musculoskeletal pain with a wide variety of diagnoses were enrolled. Patients reported their intensity of pain on the following scale: HPPS, “visual analog scale (VAS),” and “numerical rating scale (NRS). ” Patients were asked to complete another HPPS, VAS, and NRS after 2 days to determine the reproducibility of the scales. Spearman rank correlation coefficients between the HPPS and the NRS, and VAS were used to determine the validity of the scales. The correlation between the change score of HPPS, VAS, and NRS was used to determine the responsiveness of HPPS. Results of test–retest indicate that the reproducibility of HPPS was good to excellent with the intraclass correlation coefficient (ICC) value of 0.85 (95% confidence interval [CI], 0.76–0.91). The standard error of measurement (SEM) was 5.24. The minimum detectable change based on the SEM for test–retest was 14.52. The reproducibility of VAS is moderate to good with the ICC value of 0.82 (95% CI, 0.72–0.88). The reproducibility of NRS is good to excellent with the ICC value of 0.88 (95% CI, 0.81–0.92). There was a strong correlation between the HPPS and the VAS, and NRS (P < 0.01), which confirm the validity. The HPPS was responsive as the correlation of the change score of HPPS with the change score of VAS, and NRS were good (0.80 and 0.86, respectively). The HPPS is a valid and reliable scale to assess musculoskeletal pain, with psychometric properties in agreement with other comparable scale.
Analysis the Power Converting Performance of Ultrasonically Coupled Piezoelectric Receiver for Three Different Conditions

In this work, designed an ultrasonic wireless power transmission system (UWPTS) for powering implantable medical device (IMD). The parameters such as propagation loss of ultrasonic waves (attenuation coefficient in tissues ∼1dB/cm/MHz), receiver geometry, mode of vibration of receiver, and depth of power transmission have been considered to design efficient UWPTS. The frequency selection of the ultrasonic waves (UW) has vital role in efficient UWPTS design. The higher frequency of UW is not only reducing the receiver size but also reduce the depth of power transmission. Whereas choosing lower frequency increases the receiver geometry. Moreover, the receiver having geometry half of wavelength in the direction of UW propagation can give better electromechanical coupling. The UW having frequencies range 1MHz-10MHz offers wireless power transmission up to 20cm by reducing receiver size in the millimetre scale. Here we considered PZT-5H $\mathbf{1.1}\times \mathbf{1.1}\times \mathbf{1.5}\mathbf{mm}$ piezoelectric receiver to analysis power conversion performance at three different conditions such as damping (structural loss factor = 0.01), capacitive feed through (50pF), and air gap through PCB (Printed Circuit Board). The generated result shows that the damping and air gap has tremendous effect on power conversion (mechanical power to electrical power) of receiver for the frequency range 0.5MHz to 1.3MHz. At this frequency range, the effect of capacitive feed through is negligible. Though few experimental works have been reported on this system, this is the first COMSOL model to design efficient UWPTS in water by considering the effects of the above three conditions.
Energy efficient Onboard EV Charger Employing Partial Power Processing DC-DC Converter

This paper presents the two configurations of partial power processing converter for onboard electric vehicles (EVs) charging using the traditional full power processing dual active bridge DC-DC converter. The two configurations are Input Parallel and Output Series (IPOS) Series Output Parallel (ISOP) partial power converters for high- and low-voltage battery charging applications. IPOS and ISOP can bidirectional power transfer from source to battery and vice-versa through the direct and partial paths. The partial path only comprises passive and magnetic components, whereas no components are on the direct path. To validate the performance of the proposed configurations of partial power processing, converters have been simulated and tested using MATLAB / Simulink toolbox, and their results are compared with the full-power processing dual active bridge converter under the various loaded conditions. The results show that the IPOS and ISOP configurations provide an efficiency of about 94% under full load conditions, i.e., during battery charging and observed to be 4–6% higher than the full power converter configuration. Also, IPOS and ISOP schemes handle less than 50% of output power via the partial paths. Therefore, power ratings and sizes of the semiconductor and passive devices can be significantly reduced compared to the full power converter. Hence, it is observed that these two configurations are best suited for onboard EV chargers.
