Energy storage sharing strategy in distribution networks using bi-level optimization approach

In this paper, we address the energy storage management problem in distribution networks from the perspective of an independent energy storage manager (IESM) who aims to realize optimal energy storage sharing with multi-objective optimization, i.e., optimizing the system peak loads and the electricity purchase costs of the distribution company (DisCo) and its customers. To achieve the goal of the IESM, an energy storage sharing strategy is therefore proposed, which allows DisCo and customers to control the assigned energy storage. The strategy is updated day by day according to the system information change. The problem is formulated as a bi-level mathematical model where the upper level model (ULM) seeks for optimal division of energy storage among Disco and customers, and the lower level models (LLMs) represent the minimizations of the electricity purchase costs of DisCo and customers. Further, in order to enhance the computation efficiency, we transform the bi-level model into a single-level mathematical program with equilibrium constraints (MPEC) model and linearize it. Finally, we validate the effectiveness of the strategy and complement our analysis through case studies.
Chip — Module — Package interfaces

The complexity of the interfaces between packaging levels continues to increase as integration proceeds at the semiconductor chip. The increased terminal count at the chip (as a result of the increasing number of circuits and chip size) requires increasing printed circuit wiring capability in the module. As more and larger chips are packaged on the module, additional pins must be interfaced to the board. Thus, the demand for printed circuit wiring is dramatically increasing at the board level. This paper describes a design example which is carried through from chip-to-module-to-board in simple terms to illustrate the interaction between the various levels of packaging. The interfacial considerations are considered briefly with reference to new packaging developments. Most of the technology is centered on the printed circuit board.
[Analysis of chromosome karyotype of oral carcinoma-associated fibroblasts].

OBJECTIVE The purpose of this study was to investigate whether the fundamental genetic character of oral carcinoma-associated fibroblasts changes through contrasting and analyzing the oral carcinoma-associated fibroblasts and the normal fibroblasts of oral mucosa. METHODS The two kinds of cells were treated with colchicine and microsometic fluid, and then were expanded with cold acetic acid and formalized with methyl alcohol. The cells were observed under the oil microscope after Giemsa staining. The chromosome karyotype of the two kinds of cells was analyzed by Visus 2. 1. RESULTS There were not obvious differences in the way of chromosome karyotype between the oral carcinoma-associated fibroblasts and the normal fibroblasts of oral mucosa. CONCLUSION The basic genetic characteristics of the normal cells are conserved in the oral carcinoma-associated fibroblasts, which means the cells have no malignant changes.
FACIAL EXPRESSION DETECTION AND RECOGNITION SYSTEM

In this paper, the integration of face feature detection and extraction, and facial expression recognition are discussed. In this paper, we propose an algorithm that utilizes multi-stage integral projection to extract facial features. Furthermore, in this project, we propose a statistical approach to process the optical flow data to obtain the overall value for the respective feature region in the face. This approach has eliminated the requirement of accurate identification of the feature boundary. Optical flow computations are utilized to identify the directions and the amount of motions in image sequences that are caused by human facial expressions. The optical flow computation results are processed using Kalman filtering. The filtered results are given to a neural network to realize a mapping into the facial expression space. This technique is used on a set of training and testing face images. Preliminary experiments indicate an accuracy between 60% - 80% on the Kalman filtered data when recognizing four types of expressions: anger, sad, happy and surprise. In an attempt to further improve the recognition results, we proposed a technique to process the optical flow results using a statistical approach instead of using Kalman filtering. The preliminary experiments on this proposal approach produced accuracy between 70% - 100% on the original optical flow results that is better than the Kalman filter technique.
Administration of anti-Reg I and anti-PAPII antibodies worsens pancreatitis.

CONTEXT The regeneration protein family (Reg), which includes Reg I and PAPII, is expressed in pancreas acinar cells, and increases in acute pancreatitis. We have demonstrated that Reg gene knockdown worsens severity of acute pancreatitis in the rat and hypothesize that the proteins offer a protective effect in this disease. OBJECTIVE We investigated the ability of anti-Reg and anti-PAP antibody to neutralize pancreatic Reg protein and affect pancreatitis severity. INTERVENTION Pancreatitis was induced in rats by retrograde ductal injection of 4% sodium taurocholate. ANIMALS Eighty-four rats: 48 with induced pancreatitis, 30 sham operated, and 6 normal animals. SETTING Intraductal anti-Reg I and/or anti-PAPII antibody was administered at induced pancreatitis and sham operated subgroups of 6 rats each. MAIN OUTCOME MEASURE Serum and pancreata were harvested 24 and/or 48 hours later and assessed for pancreatitis severity by pancreatic wet weight, serum C-reactive protein (CRP), amylase, PAPII levels, and histopathology. RESULTS Animals induced with pancreatitis with administration of anti-Reg/PAP antibodies had significantly higher wet weights compared with taurocholate and histopathological analysis revealed that anti-Reg/PAP treated animals had worse tissue inflammation and necrosis compared with controls. Serum CRP, amylase, and Reg levels did not significantly differ between experimental and sham control groups. CONCLUSIONS Administration of anti-Reg/PAP antibody worsened taurocholate-induced organ specific pancreatitis. These data suggest that the Reg family of proteins is protective in acute pancreatitis.
Analytic signal generation-tips and traps

In this correspondence we discuss methods to produce the discrete analytic signal from a discrete real-valued signal. Such an analytic signal is complex and contains only positive frequencies. Its projection onto the real axis is the same as the original signal. Our use stems from instantaneous-frequency estimation and time-frequency signal analysis problems. For these problems the negative frequency component of real signals causes unwanted interference. The task of designing a filter to produce an approximation to the ideal analytic signal is not as simple as its formulation might suggest. Our result is that the direct methods of zeroing the negative frequencies, or using Hilbert transform filters, have undesirable defects. We present an alternative which is similar to the "quadrature" filters used in modem designs. >
Recent Progress in Anti-Obesity and Anti-Diabetes Effect of Berries

Berries are rich in polyphenols such as anthocyanins. Various favorable functions of berries cannot be explained by their anti-oxidant properties, and thus, berries are now receiving great interest as food ingredients with “beyond antioxidant” functions. In this review, we discuss the potential health benefits of anthocyanin-rich berries, with a focus on prevention and treatment of obesity and diabetes. To better understand the physiological functionality of berries, the exact molecular mechanism of their anti-obesity and anti-diabetes effect should be clarified. Additionally, the relationship of metabolites and degradation products with health benefits derived from anthocyanins needs to be elucidated. The preventive effects of berries and anthocyanin-containing foods on the metabolic syndrome are not always supported by findings of interventional studies in humans, and thus further studies are necessary. Use of standardized diets and conditions by all research groups may address this problem. Berries are tasty foods that are easy to consume, and thus, investigating their health benefits is critical for health promotion and disease prevention.
The 2009 Kuwaiti parliamentary election: the challenges and the future of the Kuwaiti democratic paradigm

This article discusses the composition of the new 2009 Parliament in Kuwait and compares changes in its composition with the outgoing one, dealing with factors which contributed to the historic victory of women and the demise of the organized political blocs. It traces Kuwait’s unique pioneering experience in democracy in the region and sheds light on how economic development and oil politics have altered the historical dynamics between state and society. It concludes by forecasting the future malaise of Kuwaiti politics if changes are not made and provides feasible recommendations to possibly overhaul the system or even amend the Constitution.
Design and Optimization for Energy-Efficient Cooperative MIMO Transmission in Ad Hoc Networks

The need to reduce energy consumption for lowering operating costs has pushed energy efficiency to become one of the major issues of current research in the field of ad hoc networks. In this paper, a new cooperative strategy of multiple-input–multiple-output (MIMO) based on spatial modulation (SM) for the randomly distributed nodes (CMIMO-SMR) in an ad hoc network is proposed to optimize the whole energy consumption of the network. In this new strategy, the head node and the assistant node are jointly set up using a cooperative technique in each cluster to obtain the diversity. In this strategy, the effect of the amount of nodes on the energy consumption is analyzed. Moreover, the different factors such as number of hops and bit error ratio (BER) for energy savings are investigated in a CMIMO-SMR-based multihop ad hoc network where the optimal number of hops and the BER relationship are derived by taking into account the transmission energy and the circuit energy, as well as the bit-recovery situation. In the simulation, it is demonstrated that CMIMO-SMR is more energy efficient compared with the existing works. Moreover, an adaptive algorithm for choosing the appropriate number of hops to minimize the energy consumption is designed when the end-to-end designated BER is required. The results demonstrate that the minimum energy consumption can be achieved by using the proposed algorithm without compromising the designated BER requirement at the destination.
PD-1 Protects against Inflammation and Myocyte Damage in T Cell-Mediated Myocarditis

PD-1, a member of the CD28 family of immune regulatory molecules, is expressed on activated T cells, interacts with its ligands, PD-L1/B7-H1 and PD-L2/B7-DC, on other cells, and delivers inhibitory signals to the T cell. We studied the role of this pathway in modulating autoreactive T cell responses in two models of myocarditis. In a CD8+ T cell-mediated adoptive transfer model, we found that compared with Pd1+/+ CD8+ T cells, Pd1−/− CD8+ T cells cause enhanced disease, with increased inflammatory infiltrate, particularly rich in neutrophils. Additionally, we show enhanced proliferation in vivo and enhanced cytotoxic activity of PD-1–deficient T lymphocytes against myocardial endothelial cells in vitro. In experimental autoimmune myocarditis, a disease model dependent on CD4+ T cells, we show that mice lacking PD-1 develop enhanced disease compared with wild-type mice. PD-1–deficient mice displayed increased inflammation, enhanced serum markers of myocardial damage, and an increased infiltration of inflammatory cells, including CD8+ T cells. Together, these studies show that PD-1 plays an important role in limiting T cell responses in the heart.
Isolation and characterization of two distinct fractions from the inner membrane of dormant Bacillus megaterium spores

Two distinct membrane bands were obtained after sucrose velocity gradient centrifugation of crude inner membranes from dormant Bacillus megaterium spores disrupted under conditions which minimized endogenous enzyme action. These two inner membrane fractions (termed LD and HD) contained similar amounts of total and individual phospholipid species. However, LD and HD differed significantly in phospholipid/protein ratios (4.3 and 0.47 mg/mg, respectively), equilibrium densities (1.12 and 1.18 g/cm3), NADH oxidase specific activity (less than 0.01 and 0.13 mumol/min X mg), and content of specific proteins. In contrast, crude membranes prepared in identical fashion from germinated spores gave only a single inner membrane band (termed G) on sucrose velocity gradients. G had a phospholipid/protein ratio of 0.98 mg/mg, an equilibrium density of 1.16 g/cm3, and an NADH oxidase specific activity of 2.1 mumol/min X mg. Essentially all of the proteins present in LD or HD or both were found in G, consistent with the latter membrane being derived from a mixture of LD and HD. No evidence was found suggesting that there is significant degradation of dormant spore inner membrane protein upon spore germination.
2016 Ieee International Conference on Big Data (big Data) Mix 'n' Match Multi-engine Analytics

—Current platforms fail to efficiently cope with the data and task heterogeneity of modern analytics workflows due to their adhesion to a single data and/or compute model. As a remedy, we present IReS, the Intelligent Resource Scheduler for complex analytics workflows executed over multi-engine environments. IReS is able to optimize a workflow with respect to a user-defined policy relying on cost and performance models of the required tasks over the available platforms. This optimization consists in allocating distinct workflow parts to the most advantageous execution and/or storage engine among the available ones and deciding on the exact amount of resources provisioned. Our current prototype supports 5 compute and 3 data engines, yet new ones can effortlessly be added to IReS by virtue of its engine-agnostic mechanisms. Our extensive experimental evaluation confirms that IReS speeds up diverse and realistic workflows by up to 30% compared to their optimal single-engine plan by automatically scattering parts of them to different execution engines and datastores. Its optimizer incurs only marginal overhead to the workflow execution performance, managing to discover the optimal execution plan within a few seconds, even for large-scale workflow instances. I. INTRODUCTION Big Data analytics have become indispensable to organizations worldwide as a means of extracting significant value out of the enormous amounts of data that stream into their businesses. That, in turn, offers organizations an unprecedented competitive advantage: The ability to identify new opportunities, take educated decisions based on historical facts, render their operations faster and more cost efficient and keep customers satisfied [1]. The volume, velocity and variety of Big Data pose new challenges to analytics, entailing a high degree of parallelism in both storage and computation: Modern datacenters host huge volumes of data over large numbers of nodes with multiple storage devices and process them using thousands or millions of cores. In the landscape of Big Data analytics, multiple and diverse execution engines and datastores have emerged as platforms of choice for specific computation types and data formats (e.g., [2], [3], [4], etc.). To alleviate the burden of building and maintaining such systems, many of them are currently either offered as-a-service by the most prevalent Cloud providers (e.g., [5], [6], [7]) or packaged in pre-cooked VM or container images for ease of deployment [8]. Still, although many approaches in the relevant literature manage to optimize the performance of single engines by automatically tuning a number of configuration parameters [9], …
The rites of righting writing: Homophone remediation in acquired dysgraphia

Abstract A homophone retraining program was implemented with a surface dysgraphic patient. Extensive pre-therapy testing suggested that lexical processing was impaired in writing but not in reading, resulting in difficulties in writing homophones and irregular words. The treatment procedure involved the pairing of the written homophone with its pictorial representation in order to link the orthography with the corresponding meaning and to enhance direct lexical access. A series of exercises and practice techniques were introduced to strengthen this route. Results revealed significant improvement in writing treated homophones and untreated irregular words but minimal generalisation to untreated homophones. Theoretical explanations for the changes are offered and the efficacy of the treatment program is demonstrated.
The Serine-Rich N-Terminal Domain of Oat Phytochrome A Helps Regulate Light Responses and Subnuclear Localization of the Photoreceptor1

Phytochrome (phy) A mediates two distinct photobiological responses in plants: the very-low-fluence response (VLFR), which can be saturated by short pulses of very-low-fluence light, and the high-irradiance response (HIR), which requires prolonged irradiation with higher fluences of far-red light (FR). To investigate whether the VLFR and HIR involve different domains within the phyA molecule, transgenic tobacco (Nicotiana tabacum cv Xanthi) and Arabidopsis seedlings expressing full-length (FL) and various deletion mutants of oat (Avena sativa) phyA were examined for their light sensitivity. Although most mutants were either partially active or inactive, a strong differential effect was observed for the Δ6-12 phyA mutant missing the serine-rich domain between amino acids 6 and 12. Δ6-12 phyA was as active as FL phyA for the VLFR of hypocotyl growth and cotyledon unfolding in Arabidopsis, and was hyperactive in the VLFR of hypocotyl growth and cotyledon unfolding in tobacco, and the VLFR blocking subsequent greening under white light in Arabidopsis. In contrast, Δ6-12 phyA showed a dominant-negative suppression of HIR in both species. In hypocotyl cells of Arabidopsis irradiated with FR phyA:green fluorescent protein (GFP) and Δ6-12 phyA:GFP fusions localized to the nucleus and coalesced into foci. The proportion of nuclei with abundant foci was enhanced by continuous compared with hourly FR provided at equal total fluence in FL phyA:GFP, and by Δ6-12 phyA mutation under hourly FR. We propose that the N-terminal serine-rich domain of phyA is involved in channeling downstream signaling via the VLFR or HIR pathways in different cellular contexts.
Improving Marketing Productivity: Introducing the HAMRAT process

In a multi-brand organisation, the brands traditionally compete for resources in some degree of isolation, whether budgets are built top down or bottom up. This paper addresses a possibly growing demand for tools to allocate resources optimally across brands and/or markets. After reviewing the theory and some of the models available to UK practitioners, we develop a decision calculus model, called HAMRAT, that can be implemented within an Excel spreadsheet. The components of HAMRAT have been available in the public domain for many years but the fact that they are rarely used implies a need for their packaging into a convenient format that can be developed by practitioners or used to benchmark models offered by agencies or consultants. “The causes and effects [of advertising] have been analyzed until they are well understood. The correct methods of procedure have been proved and established. We know what is most effective, and we act on basic laws. ”—Claude Hopkins (1922)
Naturalistic observations of smiling and laughter in human group interactions

[Although smiling and laughter have received considerable attention from researchers, little is known about the way they are displayed in naturally occurring group interactions. This aspect could be crucial if we want to understand the function of affiliative behaviours in social relationships. Naturalistic observations were conducted in areas where people could be watched interacting in small groups. Focal sampling of men and women allowed the recording of smiling and laughter frequencies, as well as group size and composition in terms of age and sex. Overall, smiling and laughter were influenced by group size and age of people involved. Smiling and laughter were also affected by other aspects of social context, depending on the type of behaviour concerned and the sex of individuals. By deriving predictions from three hypotheses — sexual advertisement, social competition, and cooperation — this study revealed that smiling and laughter are likely to be involved in the formation of cooperative relationships. , Although smiling and laughter have received considerable attention from researchers, little is known about the way they are displayed in naturally occurring group interactions.

Experiencing Part-Time Work: Temporal Tensions, Social Relations and the Work-Family Interface

Part-time work is commonly depicted as positive for women workers and their experience of work and home. Drawing on the qualitative commentaries of lower-level service workers, this study explores the temporal, social and interpersonal consequences of part-time work. While many employees liked part-time work, there was evidence that fragmented work schedules, mandated overtime and difficulties in taking time off work created tensions and problems for women in both the work and family domains. Inferior treatment also punctuated the work experiences of a number of part-time employees and served to underline their differential work status.
Psoralen and ultraviolet A in the treatment of granuloma annulare

Background: Granuloma annulare (GA) is a benign, usually self‐limiting disease. Lesions may be localized or generalized with a tendency for generalized disease to follow a chronic course. There is evidence to support psoralen and ultraviolet A (PUVA) in the treatment of GA, but little data on long‐term benefits. The purpose of this study was to investigate the effect of PUVA in the treatment of GA, and to establish clearance and remission rates.
