Enabling End-User for LV Smart Grids

In order to increase the rate of transformation of traditional grid to a future Smart Grid, there is a huge necessity for enabling the end-user to become an activity participant. Technological and financial considerations are key driving factors in empowering the end-user. From a technological point of view end-user needs to manage his own load, power generated from renewables and also in providing the services to the grid. A promising and innovative solution to meet these needs of the end user in LV network is the Open UPQC (Open Unified Power Quality Conditioner). This device has been designed to meet different tasks required by an end-user (Power Quality, Demand Response, Ancillary Service, etc.). This paper presents the Shunt Unit of Open UPQC with RES (Renewable Energy Sources) as a solution which can provide all the necessary functionalities required by an end-user in enabling him to become an active participant in electrical grid transformation. The performance of the device is demonstrated using simulation results under online and island operation modes.
Systematic wood anatomy of the Rosaceae

The wood anatomy of the Rosaceae is surveyed and analysed, based on the study of 280 species (c. 500 specimens) belonging to 62 genera from different parts of the world. Eighteen wood anatomical characters have been used for a phenetic and phylogenetic classification. In the phenetic classification, 12 groups are recognised and compared with Hutchinson’s tribes. Groups I-V accommodate a mixture of representatives from Spiraeoideae and Rosoideae genera (or tribes); Groups VI-VII comprise the Maloideae plus Cercocarpus; Groups VIII-IX are composed mainly of the tribe Quillajeae, but include Prinsepia, and exclude Exochorda; Groups X-XII represent the Prunoideae. All woody tribes recognised by Hutchinson encompass few closely similar wood anatomical groups except the Cercocarpeae. The Quillajeae, characterised by presumably primitive macromorphological characters, appear to be quite derived wood anatomically, and, according to the phylogenetic analysis, should be included in the Prunoideae or be recognised as a separate subfamily close to the Prunoideae. The wood anatomical variation patterns support a broad generic delimitation in the Maloideae, and a narrow one in the Prunoideae. The wood anatomical evidence also suggests that Cercocarpus be moved to the Maloideae, and that Sorbaria is the most derived representative in the Spiraeoideae/ Rosoideae. Prinsepia, although distinct in its wood anatomy from the Prunus alliance, still forms part of a monophyletic group together with the latter. Based on wood anatomical evidence, the subdivision of the family and the origin of the Maloideae are discussed. Wood anatomically the Rosaceae are isolated within the order Rosales. It is hypothesised that the Rosaceae might have originated in East Asia instead of in the tropics. Individual generic descriptions, a family description and a tentative wood anatomical key to the genera studied are also presented.
Body Image Concern and Gender Identities between Transgender and Cisgender Persons from Iran

Abstract The aim was to compare body image concern and gender identities between post-operative transgender and cisgender persons. Participants included 48 transgender persons (25 trans men, 23 trans women) and 48 cisgender persons (24 cismen, 24 ciswomen). The data were collected with Littleton’s Body Image Concern Inventory and the Singapore Androgyny Inventory. Results showed that body image concern was significantly higher in transgender participants compared to cisgender participants, and these scores were especially higher in trans women compared to other groups. Furthermore, trans women scored higher in the femininity subscale compared to ciswomen. Body image concern was also higher in participants with feminine gender identity compared to participants with masculine gender identity (whether they were transgender or not). Moreover, transgender persons with traditional gender identity had higher scores in body image concern in comparison to those who had nontraditional identities, as well as trans men had more Androgynous or undifferentiated identities than trans women. We also found a significant correlation between feminine subscale and body image concern. Based on our results, it seems hormonal and surgical treatments in transgender persons only can eliminate body dissatisfaction to a certain extent. The higher scores of trans women, both in body image concern and femininity, indicate that it may be harder for trans women to believe they are perceived as female by others and their bodies are adequate. Changing cultural beliefs, social values, and increasing social acceptance with the help of the media may play an important role in improving body image in the future.
Significance of the Association between Disc Degeneration Changes on Imaging and Low Back Pain: A Review Article

Low back pain (LBP) is a major health issue resulting in a huge economic burden on the community. It not only increases the medical costs directly, but also raises the disability and loss of productivity in the general population. Symptoms include local pain over the spinal area, pain radiating to the lower leg, stiffness, and muscle tension. LBP is strongly linked with intervertebral disc degeneration that is further associated with the disruption of the complex anatomy of nucleus pulposus, annulus fibrosus, and adjacent supporting structures of the spine. Change in the shape and intensity of nucleus pulposus, decreased disc height, disc herniation, vertebral endplate changes, presence of osteophyte, and posterior high intensity zones are degenerative changes found in imaging studies. Every feature is considered while grading the severity score. Modic changes, DEBIT (disc extension beyond interspace) score, and Pfirrmann criteria are some of the scoring criteria used for evaluating disc degeneration severity. Moreover, the total number and contiguous pattern of affected discs play a crucial role in symptom generation of back pain. Many studies have reported asymptomatic patients. Thus, the correlation between degeneration severity found in imaging study and symptom severity of LBP remain unclear. This review discusses and summarizes the available literature on the significance of the association between the severity of degenerative changes found in imaging study with the presence and intensity of LBP.
THE ORBIT OF A β-TRANSFORMATION CANNOT LIE IN A SMALL INTERVAL

For > 1, let : [0, 1] [0, 1) be the -transformation. We consider an invariant -orbit closure contained in a closed interval with diameter 1/, then define a function by the supremum such -orbit with frequency in base , i.e., the maximum value in -orbit closure. This paper effectively determines the maximal domain of , and explicitly specifies all possible minimal intervals containing -orbits.
Effect of mix design on the size-independent fracture energy of normal- and high-strength self-compacting concrete

Self-compacting concrete has a characteristic microstructure inherent to its specific composition. The higher content of fine particles in self-compacting concrete relative to the equivalent vibrated concrete produces a different fracture behavior that affects the main fracture parameters. In this work, a comprehensive experimental investigation of the fracture behavior of self-compacting concrete has been carried out. Twelve different self-compacting concrete mixes with compressive strength ranging from 39 to 124 MPa (wider range than in other studies) have been subjected to three-point bending tests in order to determine the specific fracture energy. The influence of the mix design and its composition (coarse aggregate fraction, the water to binder ratio and the paste to solids ratio) on its fracture behavior has been analyzed. Moreover, further evidence of the objectivity of the size-independent fracture energy results, obtained by the two most commonly used methods, has been provided on the self-compacting concrete mixes.
A STUDY ON THE ABILITY OF PRECURSOR AND ACETYLATED PRODUCT TO REFILL CHOLINERGIC VESICLES INDEPENDENTLY OF THE CYTOPLASM

Mouse forebrain minces were incubated in a Krebs or a lithium high K+ (L.K.) Krebs medium, cytoplasmic (S 3 ) and crude vesicular (P 3 ) fractions prepared and the levels of choline and acetylcholine (ACh) in each, determined. ACh levels were depleted by 70% in the P3 fraction of L.K. Krebs as compared to Krebs, incubated minces; while, s3 ACh levels were not significantly altered by the lithium incubation. Lithium treatment lowered the s3 choline content by 29%, with no significant effect upon P3 choline levels, when compared to s3 and P3 fractions of contralateral minces incubated in Krebs media. Minces, depleted of P3 ACh, were subsequently incubated in Krebs containing paraoxon (0. luM) and 0. lmN concentrations of either 14c choline or 14c homocholine. Depletion of P3 ACh resulted in an enhanced transport of extracellular 14c choline (84%) and 14c homocholine (76%), into this fraction but not into the s3 fraction. Furthermore, the depleted P3 fraction was repleted with newly synthesized 14c ACh or 14c acetylhomocholine ( 14c AHc). The ratio of 14c ACh to the total ACh in the repleted P3 fraction (0.63), exceeded that attained in the s3 fraction, (0.35). Additionally, the ratio of 14c AHc to ACh in the repleted P3 fraction (7.26), was greater than that attained in the s3 fraction (0.44). Similar results were obtained when mouse brain hippocampal minces were depleted of P3 ACh and subsequently
SSSER: Spatiotemporal Sequential and Social Embedding Rank for Successive Point-of-Interest Recommendation

Point-of-Interest (POI) recommendation is one of the important services of location-based social networks (LBSNs), which has become an important way to help users discover interesting places and increase the potential income of related companies. Although human movement presents a sequential pattern in the LBSN. There still are the following problems: (1) when modeling the sequence data, most of the existing works assume that the check-in time depends on the location transformation in the location sequence. In particular, these works emphasize the equivalent transition probabilities between locations for all users to capture the check-in sequential pattern, whereas they ignore the spatial and temporal information of personalized context in some actual personal check-in scenarios; (2) most of the existing POI recommendation algorithms fail to utilize the social information related to modeling users to improve the final recommendation performance.To tackle the above challenges, we propose a new personalized successive POI recommendation model called Spatiotemporal Sequential and Social Embedding Rank model, named SSSER. First, we use a hybrid deep learning model based on the convolution filter and multilayer perceptron model to mine the sequence pattern among the users’ checked-in locations. Then, we use the method of metric learning to model the social relationship among users. Finally, we propose a unified framework to recommend POIs combining the users’ personal interests, the check-in sequential influence and social information simultaneously for the successive POI recommendation. And the BPR standard is used to optimize the loss function to fit the user’s partial order of POIs. The experimental results on the real datasets show that our proposed POI recommendation algorithm outperforms the other state-of-the-art POI recommendation algorithms.
Miocene bivergent crustal extension in the Aegean: Evidence from the western Cyclades (Greece)

Current models for Miocene backarc extension of the Aegean region generally suggest that stretching was accommodated mainly by NE-dipping low-angle normal faults with N to NE sense of shear. A crustal-scale low-angle normal fault system trending over a length of more than 200 km forms the North Cycladic detachment system, which records a NE-directed normal shear sense separating the Cycladic Blueschist unit in the footwall from the Upper Cycladic unit in the hanging wall. Based on new structural field data, we propose the existence of another large-scale low-angle normal fault system, the West Cycladic detachment system, which is exposed on Kea, Kythnos, and Serifos, strikes over a length of at least 100 km, and has a possible extension to the SE, where the existence of a South Cycladic detachment system has been recently postulated. The West Cycladic detachment system shares many similarities with the North Cycladic detachment system, with the notable exception that the structure dips toward the SW with top-to-the-SSW kinematics. New 40 Ar/ 39 Ar and U-Th/He thermochronological data suggest that the West Cycladic detachment system accommodated extension throughout the Miocene. Since both the North and the West Cycladic detachment systems were active until the late Miocene but exhibit opposing shear sense, we propose that a large part of the stretching of the Aegean crust was accommodated by these two bivergent crustal-scale detachment systems.
Ultrasonic velocity and attenuation anisotropy of shales, Whitby, United Kingdom

We have conducted ultrasonic experiments, between 0.3 and 1 MHz, to measure velocity and attenuation (Q? 1) anisotropy of P- and S-waves in dry Whitby Mudstone samples as a function of stress. We found the degree of anisotropy to be as large as 70% for velocity and attenuation. The sensitivity of P-wave anisotropy change with applied stress is more conspicuous than for S-waves. The closure of large aspect-ratio pores (and/or micro cracks) seems to be a dominant mechanism controlling the change of anisotropy. Generally, the highest attenuation is perceived for samples that have their bed layering perpendicular (90°) to the wave path. The observed attenuation in the samples is partly due to the scattering on the different layers, and it is partly due to the intrinsic attenuation. Changes in attenuation due to crack closure during the loading stage of the experiment are an indication of the intrinsic attenuation. The remaining attenuation can then be attributed to the layer scattering. Finally, the changes in attenuation anisotropy with applied stress are more dynamic with respect to changes in velocity anisotropy, supporting the validity of a higher sensitivity of attenuation to rock property changes.
Molecular dynamics simulations to the bidirectional adhesion signaling pathway of integrin αVβ3

The bidirectional force transmission process of integrin through the cell membrane is still not well understood. Several possible mechanisms have been discussed in literature on the basis of experimental data, and in this study, we investigate these mechanisms by free and steered molecular dynamics simulations. For the first time, constant velocity pulling on the complete integrin molecule inside a dipalmitoyl‐phosphatidylcholine membrane is conducted. From the results, the most likely mechanism for inside‐out and outside‐in signaling is the switchblade model with further separation of the transmembrane helices.
The Welfare Effects of Monetary Policy

This paper examines whether monetary expansion is a beggarthyself or beggar-thy-neighbour policy. Obstfeld and Rogo¤ (1995) show that monetary expansion under producer currency pricing increases domestic and foreign overall welfare, in cases where the crosscountry substitutability is high. If the cross-country substitutability is low, then monetary expansion is a beggar-thyself policy that reduces domestic welfare and increases foreign welfare (Corsetti & Pesenti 2001; Tille 2001). In this paper, we will show that regardless of whether the cross-country substitutability is high or low, monetary expansion is always a beggar-thyself policy in the short run.

Selection of the optimal personalized treatment from multiple treatments with multivariate outcome measures

ABSTRACT In this work, we propose a novel method for individualized treatment selection when the treatment response is multivariate. For the K treatment (K ≥2) scenario we compare quantities that are suitable indexes based on outcome variables for each treatment conditional on patient-specific scores constructed from collected covariate measurements. Our method covers any number of treatments and outcome variables, and it can be applied for a broad set of models. The proposed method uses a rank aggregation technique to estimate an ordering of treatments based on ranked lists of treatment performance measures such as smooth conditional means and conditional probability of a response for one treatment dominating others. The method has the flexibility to incorporate patient and clinician preferences to the optimal treatment decision on an individual case basis. A simulation study demonstrates the performance of the proposed method in finite samples. We also present data analyses using HIV and Diabetes clinical trials data to show the applicability of the proposed procedure for real data.
Automatically Appraising the Credibility of Vaccine-Related Web Pages Shared on Social Media: A Twitter Surveillance Study

Background Tools used to appraise the credibility of health information are time-consuming to apply and require context-specific expertise, limiting their use for quickly identifying and mitigating the spread of misinformation as it emerges. Objective The aim of this study was to estimate the proportion of vaccine-related Twitter posts linked to Web pages of low credibility and measure the potential reach of those posts. Methods Sampling from 143,003 unique vaccine-related Web pages shared on Twitter between January 2017 and March 2018, we used a 7-point checklist adapted from validated tools and guidelines to manually appraise the credibility of 474 Web pages. These were used to train several classifiers (random forests, support vector machines, and recurrent neural networks) using the text from a Web page to predict whether the information satisfies each of the 7 criteria. Estimating the credibility of all other Web pages, we used the follower network to estimate potential exposures relative to a credibility score defined by the 7-point checklist. Results The best-performing classifiers were able to distinguish between low, medium, and high credibility with an accuracy of 78% and labeled low-credibility Web pages with a precision of over 96%. Across the set of unique Web pages, 11.86% (16,961 of 143,003) were estimated as low credibility and they generated 9.34% (1.64 billion of 17.6 billion) of potential exposures. The 100 most popular links to low credibility Web pages were each potentially seen by an estimated 2 million to 80 million Twitter users globally. Conclusions The results indicate that although a small minority of low-credibility Web pages reach a large audience, low-credibility Web pages tend to reach fewer users than other Web pages overall and are more commonly shared within certain subpopulations. An automatic credibility appraisal tool may be useful for finding communities of users at higher risk of exposure to low-credibility vaccine communications.
D-Stellate Neurons of the Ventral Cochlear Nucleus Decrease in Auditory Nerve-Evoked Activity during Age-Related Hearing Loss

Age-related hearing loss (ARHL) is associated with weakened inhibition in the central auditory nervous system including the cochlear nucleus. One of the main inhibitory neurons of the cochlear nucleus is the D-stellate neuron, which provides extensive glycinergic inhibition within the local neural network. It remains unclear how physiological activities of D-stellate neurons change during ARHL and what are the underlying mechanisms. Using in vitro whole-cell patch clamp technique, we studied the intrinsic membrane properties of D-stellate neurons, the changes of their firing properties, and the underlying mechanisms in CBA/CaJ mice at the ages of 3–4 months (young), 17–19 months (middle age), and 27–33 months (aged). We found that the intrinsic membrane properties of D-stellate neurons were unchanged among these three age groups. However, these neurons showed decreased firing rate with age in response to sustained auditory nerve stimulation. Further investigation showed that auditory nerve-evoked excitatory postsynaptic currents (EPSCs) were significantly reduced in strength with age. These findings suggest that D-stellate neurons receive weakened synaptic inputs from the auditory nerve and decreased sound driven activity with age, which are expected to reduce the overall inhibition and enhance the central gain in the cochlear nucleus during ARHL.
High-Frequency Trading in the Bund Futures Market

In this work, I study the impact of high-frequency trading (HFT) on price discovery and volatility in the Bund futures market. Using a new dataset based on microseconds, the focus of the study is on the reaction of high-frequency traders (HFTs) to major macroeconomic news events. I show that through their fast and strong reaction to news, HFTs contribute more to price discovery compared to Non-HFTs, but also add a higher share to noise than to permanent volatility. Moreover, I find evidence that HFTs tend to supply less liquidity after an unexpected rise in market volatility and prior to upcoming macroeconomic news events. These findings suggest that in times of high market stress, HFT behavior may exacerbate intraday price volatility and amplify the risk of market disruptions in fixed income markets.
Network modelling and computation of quickest path for service-level agreements using bi-objective optimization

This article addresses the problem related to the reliability of path after transmitting the given amount of data with the service-level agreement cooperation in the computer communication network. The links have associated with service performance factor parameter during the data transmission, and each node is associated with the requested service performance factor. In this article, first we have considered the single objective to minimize the transmission time of the quickest path problem. An algorithm for quickest path problem has been proposed for results, and furthermore, its time complexity has been shown. The problem has been extended with bi-objective optimization of the quickest path problem, which minimizes the transmission time and hybrid logarithmic reliability. An algorithm is proposed for getting the number of efficient solutions for the quickest path problem using label-correcting algorithm. The algorithms are implemented and tested on different standard benchmark network problems provided with the set of Pareto front of the results.
