Utilizing HVDC links as a energy storing device in AGC operation of hydro-thermal-gas based interconnected power systems

This paper utilizes the HVDC links as a energy storing device in automatic generation control (AGC) operation. The HVDC link has been considered as DC capacitors in which electrical energy is stored in the electro static form. This electrical energy has been utilized to assist in AGC operation. The two areas of hydro-thermal-gas generation based power systems with AC-HVDC interconnections have been considered for the investigation. Furthermore, discrete supplementary controllers have been taken for secondary control action. The comparative analysis has also been performed to demonstrate effectiveness of the proposed control strategy for HVDC links.
LOW Complexity MMSE channel estimator for downlink MC-CDMA system

Multi-carrier code division multiple access (MC-CDMA) are very assuring techniques for high speed data transmission over wireless communication channel. Generally, transmitted signals are propagated through different paths and suffer from different path delay and causes ISI and ICI effects. So, it is essential to dynamically estimate the channel frequency response before recovering the useful information. The major problems in conventional MMSE estimator is its computational complexity which arises due to matrix inversion calculation at every instant of input signal data changing. So to overcome this problem a low computation complexity MMSE channel estimation algorithms is proposed for downlink MC-CDMA system. Comparing with conventional MMSE this algorithm has advantages of low computational complexity. The Matlab execution results shows that MC-CDMA with proposed low complexity MMSE channel estimator gives the better performance than conventional MMSE estimator also MC-CDMA outperforms the OFDM systems in Rayleigh fading environment.
Long non-coding RNA CACNA1G-AS1 promotes calcium channel protein expression and positively affects human keloid fibroblast migration

Keloids are a type of benign hyperplasia that cause dermatologic dysfunction and esthetic deformity by invading adjacent normal tissues. Little is known about their etiology, therefore, they are a challenge to treat using plastic surgery. In a previous study, it was demonstrated that the expression of the long non-coding RNA CACNA1G-AS1 (CAS1) is high in keloid tissue, suggesting that CAS1 is involved in keloid formation. In the present study, the aim was to identify potential keloid target proteins by exploring CAS1 biological function during cell proliferation and migration, cytokine secretion, collagen secretion and the control of calcium channel protein expression in human keloid fibroblasts. Three biopsy samples were collected from each patient with keloids at The Peking Union Medical College Hospital, which were then used to investigate the role of CAS1 in cell proliferation and migration. CAS1 silencing was also carried out using small interfering RNA; cell factors, collagen and calcium channel protein levels were compared with control cells. The interference of CAS1 expression reached 50% compared with the control group. CACNA1G and type I collagen expression was significantly downregulated by CAS1 knockdown, while the expression of transforming growth factor-β and type III collagen was not affected. Wound healing time was longer in the CAS1-knockdown group, but there was no visible change in cell proliferation. In conclusion, CAS1 appeared to promote calcium channel protein and type I collagen expression, and to have a positive effect on cell migration in human keloid fibroblasts. Therefore it has potential as a novel therapeutic target for keloids.
MicroRNA array analysis of the regulation of microRNAs in rats exhibiting hyperplasia of mammary glands

Hyperplasia of mammary glands (HMG) is also termed mammary dysplasia. In China, the number of patients suffering from breast hyperplasia is increasing annually. MicroRNAs (miRNAs; length, 19–24 nucleotides), a group of small endogenous non-coding RNAs, post-transcriptionally regulate gene expression via RNA interference and gene silencing pathways. The cause of disease of HMG because remains unclear. Thus, the aim of the present study was to establish comprehensive profile of drug treatments following at different time intervals on rat models of differentially expressed miRNAs, using miRNA microarray data. After scanning the chip, 13 up-regulated and 20 down-regulated miRNAs were identified. MiR-31 and miR-30 exhibited different expression levels between rats exhibiting mammary gland hyperplasia treated with or without Jiedu Capsule water solution once a day for 4 weeks, and the two demonstrated a strong association with HMG and breast cancer. Therefore, the functions of these miRNAs may provide the basis for further investigation of HMG.
A rule-based classification of short message service type

Short message service (SMS) is one of the most popular means of communication due to its type of usages like one-time passwords(OTPs), banking transaction alerts, and other promotional messages. SMS is the most time-sensitive channel of communication that demands service providers to send any information globally without any delay in respective time zone. For successful implementation of this service, the Telecom Regulatory of India (TRAI) has recommended certain guidelines that must be followed for the delivery of short messages. The prevalent practice in the industry is to store rules or raw string in a database and to match with incoming SMSs in synchronous mode. However, there are various shortcomings in this traditional approach that have been also discussed in this paper. Further, to address these issues, this research work proposes a novel approach for automated classification of SMSs in real time by the SMS service using a rule-based system of database template matching. Further to validate the proposed approach, SMS database of Netcore Solutions Pvt Limited, India, has been used for training the proposed algorithm. Proposed rule-based classifier keeps learning and updating the training dataset as more SMSs are accumulated and processed through the server. Other advantages, in terms of performance metrics, of the classification using the proposed rule-based database template matching over the traditional database matching approach have been reported in this work as evaluation measures. Reported rule-based SMS classification algorithm shows highest average classification accuracy of 100% which is better as compared to the similar research works already available in the literature.
Effect of postoperative systemic antipsychotic therapy on psychiatric recurrence in patients with meningiomas

A number of patients with meningiomas and psychiatric disorders will suffer psychiatric symptom recurrence following tumorectomies. The present study reported a retrospective analysis regarding 42 cases of patients with meningiomas using complete clinical follow-up data from June 2005 to June 2013. The patients were divided into the systemic antipsychotic (SP) group (n=20) following 6months of postoperative SP therapy and the none-SP (NSP) group (n=22), who did not receive postoperative antipsychotic treatment. Patients were assessed using the Positive and Negative Syndrome Scale (PANSS) and Brief Psychiatric Rating Scale (BPRS) at the time points of prior to surgery, immediately following surgery, and 6 months, 12 months and 3 years following surgery. The effective rate, recurrence rate, rehospitalization rate and survival analysis were calculated. The BPRS score and PANSS scores (including PANSS positive, PANSS negative, PANSS general psychopathology and PANSS overall) in the SP group at 6 months, 12 months and 3 years following surgery were significantly decreased compared with the NSP group (P<0.05). The effective rate was 95, 90 and 90% at 6 months, 12 months and 3 years, respectively, in the SP group, whilst it was 68.2, 63.6 and 59%, respectively, in the NSP group, which was statistically significant (χ2=4.89, χ2=4.01 and χ2=5.12; P<0.05). The recurrence rate of the SP group was 0, 5 and 10% at 6 months, 12 months and 3 years, respectively, whilst in the NSP group it was 22.7, 31.8 and 54.5%, respectively, which was statistically significant (χ2=5.16, χ2=4.89 and χ2=9.34; P<0.05). The rehospitalization rate of the SP group was 0, 0 and 5% at 6 months, 12 months and 3 years, respectively, whilst in the NSP group it was 13.6, 22.7 and 36.4%, respectively, and the data at 12 months and 3 years was statistically significant (χ2=5.16 and χ2=6.12; P<0.05). Kaplan-Meier survival analysis indicated that the accumulative survival rates of recurrence and rehospitalization in the SP group were improved compared with the NSP group. The log-rank of recurrence was χ2=9.369 (P=0.002) and the log-rank of rehospitalization was χ2=6.330 (P=0.012). In conclusion, postoperative SP therapy is of great importance to the consolidation of mental symptoms in patients with meningiomas and psychiatric symptoms, and it may significantly reduce the recurrence and rehospitalization rates.
Comparative study on the diagnostic values of different ultrasound technologies for malignant thyroid nodules

The present study compared and analyzed the diagnostic values of B-mode ultrasound and elasticity imaging technology for the identification of benign and malignant thyroid nodules. Ninety-four patients who were diagnosed with thyroid nodules by ultrasound were chosen. All patients were checked with B-mode ultrasound and ultrasound elasticity imaging technology before surgeries. Further, the post-operative outcomes were compared with operation pathology. The pathological examination results were taken as the gold standard. The accuracy, sensitivity, specificity, positive predictive value and negative predictive values of combined ultrasound diagnosis were all obviously higher than those by the B-mode ultrasound and the ultrasound elastography method (P<0.05). In conclusion, as a new technology, ultrasound elasticity imaging technology has relatively high diagnositic value in identifying benign and malignant thyroid nodules. With its own advantages and limitations, the ultrasound elasticity imaging technology could effectively complement B-mode ultrasound, and improve the sensitivity, specificity and accuracy of ultrasound diagnosis for thyroid nodules.
Fuzzy controlled suturing force calculation in minimally invasive robotic surgery

In today's world there is an increasing need to create artificial arms for different situations where human interaction is difficult or impossible. They may involve taking readings from an active volcano or diffusing a bomb. This study proposes to build a robotic arm to control suturing speed in Minimally Invasive Robotic Surgery (MIRS) and suturing speed is controlled by information about variation of muscle thickness. The development of this arm is based on ATmega2560 platform along with a personal computer for image processing, which will all be interfaced with each other using serial communication. Finally, this prototype of the arm is expected to overcome the suturing difficulties in MIRS.
Measuring subjective well-being in later life : a review

This working paper assesses self-reported measures of subjective well-being in later life. In the first place, an overview of the theoretical background of a number of measures, focusing on those present in the English Longitudinal Study of Ageing (ELSA), is given. Secondly, the structure of these measurements and the interrelations between them are tested using confirmatory factor analysis. Thirdly, the cross-cultural measurement equivalence of the CASP-scale, a eudaimonic measure developed specifically for older adults, is testing using the Survey of Health, Ageing and Retirement in Europe (SHARE). These analyses reveal that it makes sense to distinguish affective, cognitive and eudaimonic measures of well-being empirically, but that these measures are more closely interrelated than one would expect on the base of theory alone. The analysis on CASP in SHARE reveals that the scale can be used to investigate differences in eudaimonic and hedonic subjective well-being across Europe, as partial scalar measurement equivalence is confirmed.

1 Motion Intention Estimation for Active Power-Assist 2 Lower Limb Exoskeleton Robot ( APAL ) 3

2 Shenzhen Academy of Aerospace Technology, Shenzhen 518000, China; Email: xin.wang@chinasaat.com 7 (X.W.). 8 * Corresponding author: zhafusheng@hit.edu. cn; Tel. : +86-0451-86414174 9 10 11 Abstract: The active power-assist function greatly expands the potential applications of exoskeleton 12 robots, yet the motion intention estimation (MIE) for active power-assist strategy is quite problematic. 13 Through the analysis of the conduction path and the different stage manifestations of motion 14 intention in human body, we confirmed that the joint torque of human body meets the basic 15 requirements of MIE for the active power-assist that we suggest, namely: (i) it reflects the direction 16 and intensity of the wearer’s efforts; (ii) it precedes the human limb motion; (iii) it generates real-time 17 and continuous output. Thus, an online calculation method of human joint torque was proposed. The 18 sensing system integrated in exoskeleton robots was designed to perceive motion data and foot 19 contact force of a human body. A special inverse dynamics with a parameterized model of the human 20 body was proposed. Contrast experiments were carried out with the motion capture system, which 21 results’ accuracy and similarity were evaluated via the root mean square error and correlation 22 coefficient. The comparative analysis of two synchronous results shows good accuracy of the 23 proposed MIE method, which lays the foundation for the realization of active power-assist. 24
Climate warming and the decline of amphibians and reptiles in Europe

Aim We explore the relationship between current European distributions of amphibian and reptile species and observed climate, and project species potential distributions into the future. Potential impacts of climate warming are assessed by quantifying the magnitude and direction of modelled distributional shifts for every species. In particular we ask, first, what proportion of amphibian and reptile species are projected to lose and gain suitable climate space in the future? Secondly, do species projections vary according to taxonomic, spatial or environmental properties? And thirdly, what climate factors might be driving projections of loss or gain in suitable environments for species?
Hormonal response of Arctic fox females to short- and long-term stress.

The aim of this study was to determine the extent of the hormonal response of Arctic fox females exposed to two types of stress: short-term and long-term, combined with adaptation to new environmental con - ditions. Short-term stress (20 min) was investigated in 34 females on farm A in the Wielkopolska province. The testing procedure involved capturing of the animals, their immobilisation, phenotype evaluation, and placing in target cages. Blood for laboratory examinations was collected from the vena cephalica antebrachii three times: on the day of the test, directly after the procedure and after three days. Long-term stress (8 h), combined with adaptation to new environmental conditions, was examined in 30 females which were purchased from a farm in the Lodzkie province (farm B). The testing procedure involved selection and capture of the animals, immobilisa - tion and transfer from the pavilion, blood collection and placing of animals in a transport cage. Transport of the animals to the target farm (farm A) lasted approximately 8 h. Blood was collected five times in total, i.e. before transport (on farm B), after the transport to farm A, and then after three days, whereas the last two samplings were conducted at a 5- and 15-day interval from the third blood collection. The control group consisted of 20 randomly selected females from farm A. Blood from these animals was collected twice - at the beginning and at the end of the experiment. Changes in hormone concentrations (cortisol and testosterone) were adopted as a measure of sensitivity to a stressor. Blood hormones were analysed using a radio-immunological method. The course of stress reaction was affected by exposure time and stressor intensity, and significant changes in cortisol ( P ≤ 0.01) and testosterone ( P ≤ 0.05) concentrations were noted among individuals subjected to both short-term and long-term stress. Increased cortisol concentrations were maintained for a longer time in the group of Arctic fox females exposed to a long-term stress. In conclusion, the course of a stress reaction is affected by the duration of exposure and intensity of the stressor, and the strong stress reaction to zootechnical treatments and transport confirms the lack of complete domestication of this species.
Strong normalization of lambda-Sym-Prop and lambda bare-mumu tilde *-calculi

In this paper we give an arithmetical proof of the strong normalization of λ Prop of Berardi and Barbanera [1], which can be considered as a formulaeas-types translation of classical propositional logic in natural deduction style. Then we give a translation between the λ Prop-calculus and the λμμ̃ ∗-calculus, which is the implicational part of the λμμ̃-calculus invented by Curien and Herbelin [3] extended with negation. In this paper we adapt the method of [4] for proving strong normalization. The novelty in our proof is the notion of zoom-in sequences of redexes, which leads us directly to the proofs of the main theorems.
Placement to Optimize Label Placement and Quantity

Label placement is a tedious task in map design, and its automation has long been a goal for researchers in cartography, but also in computational geometry. Methods that search for an optimal or nearly optimal solution that satisfies a set of constraints, such as label overlapping, have been proposed in the literature. Most of these methods mainly focus on finding the optimal position for a given set of labels, but rarely allow the removal of labels as part of the optimization. This paper proposes to apply an optimization technique called Reversible-Jump Markov Chain Monte Carlo that enables to easily model the removal or addition during the optimization iterations. The method, quite preliminary for now, is tested on a real dataset, and the first results are encouraging.
Submitting to the Follower Label Followership, Positive Affect, and Extra-Role Behaviors

Although the importance of followership has been discussed in organizational literature, negative connotations attached to the follower label persist, including followers' lack of ability and power. In two studies, we found evidence for negative effects of the follower label. Participants who were labeled a follower (Study 1), or self-labeled as followers in their jobs (Study 2), reported lower positive affect, and in turn, fewer extra-role behaviors. These findings suggest that followers might be at risk for reinforcing their negative stereotypes by avoiding opportunities to show their abilities and demonstrate their independence. Recommendations for leaders and opportunities for future research are discussed.
Alignment of Cells and Extracellular Matrix Within Tissue- Engineered Substitutes

Most of the cells in our body are in direct contact with extracellular matrix (ECM) compo‐ nents which constitute a complex network of nano-scale proteins and glycosaminoglycans. Those cells constantly remodel the ECM by different processes. They build it by secreting dif‐ ferent proteins such as collagen, proteoglycans, laminins or degrade it by producing factors such as matrix metalloproteinase (MMP). Cells interact with the ECM via specific receptors, the integrins [1]. They also organize this matrix, guided by different stimuli, to generate pat‐ terns, essential for tissue and organ functions. Reciprocally, cells are guided by the ECM, they modify their morphology and phenotype depending on the protein types and organization via bidirectional integrin signaling [2-4]. In the growing field of tissue engineering [5], control of these aspects are of the utmost importance to create constructs that closely mimic native tis‐ sues. To do so, we must take into account the composition of the scaffold (synthetic, natural, biodegradable or not), its organization and the dimension of the structure.
Antimicrobial effects of topical skin cream containing natural oil mixtures against Staphylococcus pseudintermedius and Malassezia pachydermatis.

The objective of this study was to evaluate the in vitro efficacy of a topical skin cream containing a mixture of emu oil, jojoba oil, avocado oil, and tea tree oil against the canine skin pathogens Staphylococcus pseudintermedius and Malassezia pachydermatis. Three S. pseudintermedius isolates from dogs and a type strain of M. pachydermatis were used. Based on the standards of the Clinical and Laboratory Standards Institute, the minimal inhibitory concentration (MIC) and the minimal bactericidal/fungicidal concentration (MBC/MFC) were determined. In addition, microbial inactivation time was determined for both pathogens. The MICs against S. pseudintermedius and M. pachydermatis were 0.23% and 0.63%, while the MBC/MFCs were 7.5% and 5%, respectively. In assessments of the microbial inactivation time, after 12 h of incubation with the cream, the growth of both pathogens was com - pletely inhibited. These results suggest that the skin cream tested here can be used as a substitute for generally used antibiotic/antifungal agents.
Comparison between Three-Dimensional Navigator-Gated Whole-Heart MRI and Two-Dimensional Cine MRI in Quantifying Ventricular Volumes

Objective To test whether the method utilizing three-dimensional (3D) whole-heart MRI has an additional benefit over that utilizing conventional two-dimensional (2D) cine MRI in quantifying ventricular volumes. Materials and Methods In 110 patients with congenital heart disease, a navigator-gated, 3D whole-heart MRI during end-systole (ES) and end-diastole (ED), 2D short-axis cine MRI, and phase contrast MRI of the great arteries were acquired. Ventricular volumes were measured by using a 3D threshold-based segmentation for 3D whole-heart MRI and by using a simplified contouring for 2D cine MRI. The cardiac trigger delays of 3D whole-heart MRI were compared with those of a 2D cine MRI. The stroke volumes calculated from the ventricular volumes were compared with the arterial flow volumes, measured by phase contrast MRI. Results The ES and ED trigger delays of whole-heart MRI were significantly less than cine MRI for both the left ventricle (−16.8 ± 35.9 ms for ES, −59.0 ± 90.4 ms for ED; p < 0.001) and the right ventricle (−58.8 ± 30.6 ms for ES, −104.9 ± 92.7 ms for ED; p < 0.001). Compared with the arterial flow volumes, 2D cine MRI significantly overestimated the left ventricular stroke volumes (8.7 ± 8.9 mL, p < 0.001) and the 3D whole-heart MRI significantly underestimated the right ventricular stroke volumes (−22.7 ± 22.9 mL, p < 0.001). Conclusion Three-dimensional whole-heart MRI is often subject to early timing of the ED phase, potentially leading to the underestimation of the right ventricular stroke volumes.
