Network-Constrained AC Unit Commitment Under Uncertainty: A Benders’ Decomposition Approach

This paper proposes an efficient solution approach based on Benders' decomposition to solve a network-constrained ac unit commitment problem under uncertainty. The wind power production is the only source of uncertainty considered in this paper, which is modeled through a suitable set of scenarios. The proposed model is formulated as a two-stage stochastic programming problem, whose first-stage refers to the day-ahead market, and whose second-stage represents real-time operation. The proposed Benders' approach allows decomposing the original problem, which is mixed-integer nonlinear and generally intractable, into a mixed-integer linear master problem and a set of nonlinear, but continuous subproblems, one per scenario. In addition, to temporally decompose the proposed ac unit commitment problem, a heuristic technique is used to relax the inter-temporal ramping constraints of the generating units. Numerical results from a case study based on the IEEE one-area reliability test system (RTS) demonstrate the usefulness of the proposed approach.
Joint Coloring-Based Resource Allocation and Power Reduction in Dense Small Cell Networks

Deployment of small cells within macrocell layout is a promising approach to meet the rapid growth of traffic demand. Cell range expansion (CRE) has been introduced into LTE-Advanced to balance cell load. Small cell CRE users may suffer severe downlink (DL) co-tier and cross-tier interference introduced by dense deployment of small cells. In this paper, we propose a joint coloring-based resource allocation and power reduction scheme to mitigate interference to CRE users while maintaining the network throughput. In order to mitigate the co-tier interference, we firstly group CRE users based on interference graph by coloring and allocate orthogonal resources to different groups. Then, small base stations (SBSs) reduce power on resources occupied by CRE users in other SBSs. In order to alleviate the cross-tier interference, macro base stations (MBSs) power reduction is provided based on a utility function. We apply particle swarm optimization (PSO) strategy to obtain the optimal power. System level simulation results show that our proposed algorithm can greatly improve the CRE user throughput with slightly sacrificing the macrocell throughput. Meanwhile, it can improve the network energy efficiency (EE).
Effects of Temperature and Controlled Atmospheres on Codling Moth Metabolism

ABSTRACT Although controlled atmosphere temperature treatments are effective in controlling codling moth, Cydia pomonella (L.), in fruit, the mechanism by which this combination treatment kills the larvae is unknown. Differential scanning calorimetry was used to determine the effects of elevated temperatures, low O2, and high CO2 on the metabolic heat rate of fifth-instar codling moths. Total ATP levels also were determined. Metabolic heat rates in air increased from 0 to 30°C and decreased above 30°C. Heat rates measured isothermally at 23°C under decreased O2 or increased CO2 were lower than those in air with the lowest in 1 kPa O2 and 1 kPa O2 + 15 kPa CO2, Continuous temperature scans from 23 to 44.5°C under low O2 and high CO2 atmospheres produced lower metabolic heat rates than scans under air. Low O2 atmospheres produced the lowest ATP levels, and high concentrations of CO2 produced the highest ATP levels. These results indicate that heat treatments under controlled atmospheres have a dramatic effect on codling moth metabolism, low O2 prevents ATP synthesis, and high CO2 prevents use of ATP.
SUBOPTIMAL INVESTMENTS AND M&A DEALS IN EMERGING CAPITAL MARKETS

This paper focuses on the efficiency of target-company investment decisions before and after Merger & Acquisition deals. We study whether M&A deals help to solve the problem of suboptimal investment after the acquisition. Using a sample of 145 target companies from BRICS countries that were acquired during the period 2004-2014, we outline those that had over- or underinvested before the deal and show that more than half the companies managed to optimize the investment level after the deal. We determine the key factors that improve the inefficiency of investment decisions and demonstrate that the industry and country have an impact on the degree of suboptimal investment.
Comparison of CATEGO-Derived ICD–8 and DSM–III Classifications using the Composite International Diagnostic Interview in Severely Ill Subjects

Two classifications, DSM–III and catego4–derived ICD–8, included in the CIDI, are compared in 63 in-patients and out-patients with a broad range of psychiatric illness. Agreement for main diagnosis between these classifications was statistically significant for two time frames, the present state and lifetime. However, while diagnostic assignment by catego4 remained fairly constant between time frames, there was a marked shift in DSM–III-assigned diagnosis, with cases changing from anxiety state diagnosis (present state) to affective disorder (lifetime). Thirty-nine subjects were assigned a DSM–III diagnosis of affective disorder for lifetime illness compared with 21 assigned to this diagnostic group by catego4.

Investigating the relationship between watching satellite channels and intimacy and marital satisfaction of couples in Isfahan, Iran, in 2014

Background: In the age of communication and media that families are rapidly driven towards using satellite channels and other media, considering family health in this regard is essential. A determinant of health is marital satisfaction. The aim of this study was to investigate the relationship between watching satellite channels and intimacy and marital satisfaction in Isfahan, Iran. Materials and Methods: This cross-sectional and correlational study was conducted on one group of 480 couples (n = 960) participating from 8 health-treatment centers in Isfahan. Multi-stage cluster sampling was used in this study. Inclusion criteria included at least 2 years of marriage. After completion of Bagarozzi's Marital Intimacy Questionnaire and ENRICH Marital Inventory, the couples were divided into two groups based on watching satellite networks. Data were analyzed using SPSS 18. Results: There was a significant relationship between intimacy and marital satisfaction in both viewers and non-viewers of satellite channels (P < 0.050). Average duration of couple's interaction in the satellite viewing group was 22.4 minutes and in non-viewers group was 47.95 min. In addition, the duration of interaction had a significant relationship with marital satisfaction and intimacy (P < 0.050). Conclusions: This study showed that watching satellite channels reduced the intimacy and marital satisfaction of the couples, and duration of interaction among the couples.
Laterality of Cerebral Function: Relations with Anxiety, Repression, and Perception

Based on two factor analyses of data from 67 right-handed undergraduates, a laterality quotient based on forward memory spans, spatial minus digit, divided by their sum, was devised. The hemispheric balance factor for which this quotient served as the principal marker had significant positive loadings by the laterality quotient for the Edinburgh Handedness Questionnaire and by a measure of repressive tendencies, the Marlowe-Crowne Social Desirability Scale. Scores from this factor were positively related to global as opposed to analytic perception as measured by the Navon tachistoscopic task. This factor was unrelated to the trait anxiety and working short-term memory factors which also emerged. Trait anxiety was negatively related to global perception. The results raise the possibility that greater degrees of right-handedness may be related to the release of the nondominant right hemisphere from inhibition and that working short-term memory may not be lateralized.
Compliant control of a space robot with multi arms for capturing large tumbling target

When a chaser with multi arms grasps a large tumbling target, the base of chaser and the target cannot reach relative static immediately, the residual angular momentum between them need to be exchanged between each other to achieve relatively static. In the process, the arms are susceptible to damage for the external impulse force. Based on the characteristics of large tumbling space debris, this paper proposes an effective method for whole-body compliant control of capturing space debris safety. Firstly, the kinematics and dynamics models are established. Secondly, to analyze the characteristics of capturing of large tumbling target, a simplified kinematics model about the center of mass of chaser is established. Subsequently, we propose a method to distribute the desired external force to each arm optimized, and propose a regulator based on the dissipation vectors. With a distributer of minimum L2 norm and a regulator based on the dissipation vectors, the chaser can control the arms to avoid damage from external forces effectively. Finally, simulation results are appended, and the effectiveness of the compliant control strategy is verified by comparing the scenes with and without compliant controller.
Gene expression and silencing of activin receptor type 2A (ACVR2A) in myoblast cells of chicken

Abstract Activin receptor type 2A (ACVR2A) acts as receptor for myostatin (MSTN) protein involved in inhibiting satellite cell proliferation and differentiation. The importance of the ACVR2A gene during embryonic and post-hatch periods in broiler and layer chicken was studied in an in vitro cell culture system. The expression pattern of the ACVR2A gene during embryonic stages was similar in broiler and layer lines. Post-hatch expression of the ACVR2A gene varied significantly between broiler and layer lines. Five shRNA molecules were designed to knockdown expression of the ACVR2A gene in chicken myoblast cells. The silencing of the ACVR2A gene in a cell culture system varied from 60% to 82%. It is concluded that between broiler and layer lines, there were no significant changes in expression of the ACVR2A gene during embryonic stages but it varied significantly during the post-hatch period. The shRNA showed silencing of the ACVR2A gene under an in vitro cell culture system.
Assessments of Lumbar Flexion Range of Motion: Intertester Reliability and Concurrent Validity of 2 Commonly Used Clinical Tests

Study Design. Cross-sectional. Objective. To compare intertester reliability and concurrent validity of 2 frequently used methods for assessing lumbar flexion range of motion: the fingertip-to-floor distance (FFD) test and the modified Schober (mSchober) test. Summary of Background Data. An assessment of lumbar flexion range of motion is often incorporated in the clinical evaluation of patients with low back pain, as well as in clinical studies when examining the effects of different therapies on these patients. In both cases, the validity and reliability of assessment methods are important. Methods. The FFD test and the mSchober test were used in a heterogeneous study sample (n = 98) including patients with low back pain, pelvic girdle pain, and individuals without pain in either of these areas. Each participant was examined by 2 of 3 randomly selected assessors on the same day. Intraclass correlation coefficient3,1, together with the Bland and Altman plot, were used to examine intertester reliability. Absolute reliability was calculated by the smallest detectable change. The relationship between the 2 tests was measured using Pearson correlation coefficient (r), which was used as the measure of concurrent validity. Results. The FFD test and the mSchober test showed an intraclass correlation coefficient of 0.93 and 0.77, and a smallest detectable change of 9.8 and 1.8 cm, respectively. There was a medium negative correlation between the 2 tests; an increase in the mSchober test resulted in a decrease in the FFD test (r = −0.47, P ⩽ 0.001). Conclusion. In our heterogeneous study sample, the FFD and the mSchober test showed excellent intertester reliability but with a relatively large smallest detectable change. However, the medium correlation between these 2 tests to measure lumbar flexion range of motion indicates that they do not fully assess the same phenomenon and hence should be used in combination when examining patients.

Quantitative structure-activity relationship ( QSAR ) studies on bioactive cyclopeptides

Cyclopeptides show a variety of structures, from cyclodipeptides through cycloheptaand octapeptides to cyclotides with 30 amino acids, which can be found in bacteria, insects, higher plants, fungi, animals, and humans. Peptides and in particular cyclopeptides are therapeutic targets which play an important role in medicinal chemistry, including drug design and quantitative structure-activity relationships (QSARs). However, few QSAR studies have been carried out on cyclopeptides in comparison with small organic molecules. Some structural features, substructures, and functional groups contribute to enhance the bioactivity. Configurational and conformational studies of cyclopeptides from plant and fungal origin were analysed, and related to antitumour activity and toxicity. Some physico-chemical properties, e.g., partition coefficient (log P) and several molecular parameters have been found to be relevant for activity. QSAR models, including a variety of descriptors, have been applied to synthetic and natural * Research Members of the National Research Council of Argentina (CONICET).

Dopamine terminals synapse on callosal projection neurons in the rat prefrontal cortex

Dopamine (DA) afferents to the prefrontal cortex (PFC) play an important role in the cognitive functions subserved by this cortical area. Within the PFC, DA terminals synapse onto the distal dendrites of both local circuit neurons and pyramidal projection cells. We have previously demonstrated in the rat PFC that some of the dendrites and spines postsynaptic to DA terminals arise from pyramidal neurons that project to the nucleus accumbens. However, it is not known whether the pyramidal cells that give rise to callosal intercortical connections of the PFC also receive DA synaptic input. To address this question, retrograde tract tracing using an attenuated strain of pseudorabies virus (PRV‐Bartha) was combined with immunocytochemistry for tyrosine hydroxylase (TH) to identify DA terminals in the PFC. Thirty‐six to 40 hours following injection of PRV into the contralateral PFC, numerous callosal projection neurons were extensively labeled throughout their dendritic trees, with no evidence of PRV trans‐synaptic passage. In tissue prepared for electron microscopy, labeling for PRV was distributed throughout pyramidal cell somata and extended into distal dendrites and dendritic spines. Some PRV‐labeled dendrites and spines received symmetric synaptic input from terminals containing peroxidase labeling for TH. These results demonstrate that DA terminals synapse onto the distal dendrites of callosally projecting PFC neurons and suggest substrates through which DA may modulate interhemispheric cortical communication.

Registro global de nuvens de pontos RGB-D em tempo real usando fluxo óptico e marcadores

Registration of point clouds captured by depth sensors is an important task in 3D reconstruction applications based on computer vision. In many applications with strict performance requirements, the registration should be executed not only with precision, but also in the same frequency as data is acquired by the sensor. This thesis proposes the use of the pyramidal sparse optical flow algorithm to incrementally register point clouds captured by RGB-D sensors (e.g. Microsoft Kinect) in real time. The accumulated error inherent to the process is posteriorly minimized by utilizing a marker and pose graph optimization. Experimental results gathered by processing several RGB-D datasets validate the system proposed by this thesis in visual odometry and simultaneous localization and mapping (SLAM) applications.
Preparation, Characterization and Pharmacokinetics of Liposomes-Encapsulated Cyclodextrins Inclusion Complexes for Hydrophobic Drugs

Liposomes-encapsulated indomethacin/cyclodextrins (IMC/ CD) inclusion complexes were prepared. The characteristics and pharmacokinetics of the combined system were investigated. The high drug entrapment values of 2.38 ± 0.16 μg/mg and 2.48 ± 0.12 μ g/mg for liposomes-encapsulated IMC/ β-CD and IMC/HP-β-CD inclusion complexes were achieved, as only 1.60 ± 0.09 μ g/mg for conventional liposomes. Encapsulating IMC/CD inclusion complexes into liposomes resulted in a slow release of drug. Following intravenous administration, both liposomes-encapsulated inclusion complexes showed significantly improved AUC0 − ∞ compared with that of conventional liposomes (p < 0.05). After intramuscular administration, Cmax has been increased to 5.21 ± 1.14 μ g · ml−1 and 6.02 ± 1.22 μg · ml− 1 for liposomes-encapsulated IMC/ β -CD and IMC/HP-β -CD inclusion complexes, respectively, whereas only 2.43 ± 0.69 μg · ml− 1 for liposomes-encapsulated free drug (p < 0.01).
The level of risk disclosure in listed banks: evidence from Saudi Arabia

This study contributes to the existing risk disclosure literature in emerging economies, in particular Saudi Arabia (SA), by examining the levels of risk disclosure in the annual reports of both Islamic and non-Islamic listed banks. This investigation uses a manual content analysis method to examine all Saudi listed banks from 2009 to 2013. This study also develops two holistic risk disclosure indices to measure the levels of risk disclosure in both Islamic and non-Islamic banks. The empirical analysis shows that Islamic banks report less risk information than non-Islamic banks. However, the analysis also reveals that both Islamic and non-Islamic banks report relatively the same amount of risk information regarding the banks’ universal items. Furthermore, the empirical analysis shows that Islamic banks report very low risk disclosure items. The study’s findings have practical implications. They inform the regulators about the current level of risk disclosure in all Saudi listed banks (Islamic and non-Islamic). For example, the findings show that Islamic banks report less risk information than their non-Islamic counterparts. The practical implications for managers from these findings are that in order to keep investors satisfied, banks with low levels of risk disclosure should enhance their reporting practices. This will help investors when making investment decisions. To the best of the researchers’ knowledge, no prior research has previously been conducted on the levels of risk disclosure in Saudi Arabian listed banks. Therefore, this is the first study to examine the levels of risk disclosure in the context of Saudi Arabia.
