Formation control for quadrotor swarm systems: Algorithms and experiments

Formation control problems for quadrotor swarm systems are investigated. Firstly, for the formation control, the quadrotor is regarded as a point-mass system, and the dynamics of each quadrotor is modeled by double integrator. Then a consensus based formation protocol is presented for quadrotor swarm systems to achieve the desired time-varying formation. Formation control problems for swarm systems are transformed into consensus problems. Necessary and sufficient conditions for quadrotor swarm systems to achieve time-varying formations are proposed. Moreover, a quadrotor formation platform which consists of three quadrotors is introduced. Finally, simulation and experimental examples are presented for the quadrotor swarm system to achieve a time-varying formation respectively.
Relative cerebral blood volume measurements in intracranial mass lesions: interobserver and intraobserver reproducibility study.

PURPOSE To assess inter- and intraobserver reproducibility for different techniques of measuring relative cerebral blood volume (rCBV) in patients with intracranial mass lesions. MATERIALS AND METHODS Three independent observers (neuroradiology fellows) who were blinded to the histopathologic diagnosis performed rCBV measurements in 50 patients with various intracranial mass lesions. Three different methods were compared. With method 1, placement of a single region of interest was guided by a color overlay map. With methods 2 and 3, the highest rCBV value and the mean of repeated rCBV measurements, respectively, were recorded. Calculations of the intraclass correlation coefficient, coefficient of variation (CV), and descriptive statistics were used to determine the levels of reproducibility. A multiple linear regression model was used to evaluate for possible explanatory factors for interobserver variance. RESULTS Method 2 had, overall, the best reproducibility of all techniques, with an intraclass interobserver correlation coefficient of 0.71 (indicating good agreement), interobserver CV of 30%, and intraobserver CV in the range of 32%-41%. Measurement variations between observers correlated significantly (P <.001) with increasing rCBV values. CONCLUSION In this study, interobserver and intraobserver reproducibility of rCBV measurements were clinically acceptable.
Slipping and holding minds: A psychosocial analysis of maternal subjectivity in relation to childhood disability

Background This paper elucidates a methodological approach to interview text that tries to acknowledge the psychosocial nature of disability and thereby ensuring that empirical work in disability studies complements theoretical arguments already developed. Objectives The aim of this study is to outline a psychosocial conceptualisation of maternal subjectivity in relation to childhood disability and to apply this conceptualisation as an analytic tool to segments of an interview with a mother of a child with physical and developmental disabilities. Method Drawing on psychoanalysis and attachment literature alongside critical social psychology we take readers through the analysis of an interview extract with a particular mother. Through a fine grained analysis, we demonstrate the value of attending to the affective processes in and around the text rooted in the particular intersubjective exchange (‘here and how’) of the interview and the particular socio-historical context (‘there and then’) in which the mother, child and researcher are located. Findings The reading draws attention to discourses that position this particular mother and her children in particular ways while also pointing to investments in these discourses such that these discourses are not purely social but play affective functions. Conclusion This paper demonstrates the value of using multiple lenses to read the text, seeking to understand what is going on from within each lens (discursive/social, interpersonal, intrapsychic), while also seeking to disrupt this understanding as we take up the position of a different lens. This approach enables us to hold onto the complexity and locatedness of maternal subjectivity for mothers of children with disabilities.
Prognosis of Hepatocellular Carcinoma: The BCLC Staging Classification

The classifications of hepatocellular carcinoma (HCC) currently used are based on prognostic factors obtained from studies performed years ago when most tumors were diagnosed at advanced stages and the survival rates were substantially poor. Recent investigations have reviewed the survival of early tumors properly selected to receive radical therapies and the natural outcome of nonsurgical HCC patients. These data enable a new staging system to be proposed, the Barcelona Clinic Liver Cancer (BCLC) staging classification, that comprises four stages that select the best candidates for the best therapies currently available. Early stage (A) includes patients with asymptomatic early tumors suitable for radical therapies--resection, transplantation or percutaneous treatments. Intermediate stage (B) comprises patients with asymptomatic multinodular HCC. Advanced stage (C) includes patients with symptomatic tumors and/or an invasive tumoral pattern (vascular invasion/extrahepatic spread). Stage B and C patients may receive palliative treatments/new agents in the setting of phase II investigations or randomized controlled trials. End-stage disease (D) contain patients with extremely grim prognosis (Okuda stage III or PST 3-4) that should merely receive symptomatic treatment.
Measuring Uncertainty and its Impact on a Small Open Economy

We study the effect of uncertainty in New Zealand, a small open economy, by considering global and New Zealandâ€ specific uncertainty proxies, including several USâ€ and globalâ€ centric measures and two novel New Zealandâ€ specific uncertainty proxies constructed using surveys of New Zealand firms and professional forecasters. We study the effect of uncertainty on a set of New Zealand macroeconomic variables. While all of the uncertainty proxies contain valuable information to understand macroeconomic fluctuations in New Zealand, a simple SVAR analysis suggests that global uncertainty is more important than domestic uncertainty in driving the New Zealand business cycle. The implications of uncertainty for monetary policy largely depend on how heightened uncertainty interacts with monetary policy objectives.
Low-dose metronomic delivery of cyclophosphamide is less detrimental to granulosa cell viability, ovarian function, and fertility than maximum tolerated dose delivery in the mouse†

Abstract Chemotherapy can cause early menopause or infertility in women and have a profound negative impact on the quality of life of young female cancer survivors. Various factors are known to influence the risk of chemotherapy-induced ovarian failure, including the drug dose and treatment duration; however, the scheduling of dose administration has not yet been evaluated as an independent risk factor. We hypothesized that low-dose metronomic (LDM) chemotherapy scheduling would be less detrimental to ovarian function than the traditional maximum tolerated dose (MTD) strategy. In vitro, MTD cyclophosphamide exposure resulted in decreased proliferation and increased granulosa cell apoptosis, while cells treated with LDM cyclophosphamide were not different from untreated controls. Treatments of MTD cyclophosphamide induced high levels of follicle atresia and enhanced follicle recruitment inmice. In contrast, LDM delivery of an equivalent dose of cyclophosphamide reduced growing follicle numbers, but was not associated with higher levels of follicle atresia or recruitment. MTD cyclophosphamide induced significant vascular disruption and DNA damage in vivo, while LDM chemotherapy with equal cumulative amounts of cyclophosphamide was not different from controls. MTD chemotherapy also had a negative effect on mouse-fertility outcomes. Our findings suggest that LDM scheduling could potentially minimize the long-term effects of cyclophosphamide on female fertility by preventing follicle depletion from enhanced activation. Summary Sentence Metronomic chemotherapy scheduling has an ovary-sparing effect compared to maximum tolerated dose chemotherapy in the mouse.
Chronic Lateral Ankle Instability

Chronic lateral ankle instability may be present in as many as 10% to 30% of people suffering from acute lateral ankle ligament injuries. Ankle instability has been referred to as either functional instability or mechanical instability. Management options consist of either nonoperative or operative treatment, with the majority of the literature emphasizing operative management for chronic instability. Long-term studies assessing the different types of available operative repairs have now been published. This review article discusses chronic lateral ankle ligament instability from a functional, anatomical point of view. The indications for treatment, nonoperative and operative treatment, as well as the biomechanical information available regarding these methods of treatment are considered. The major emphasis of this review is discussion and analysis of the many different surgical treatment options. Following this review, we presently recommend anatomical repair to the bone of both the anterior talofibular ligament and the calcaneofibular ligament, together with imbrication of the ligaments. In patients with hypermobility, long-standing instability, or arthritis, reconstruction using the Chrisman-Snook technique is recommended.
Comparing sorting algorithm complexity based on control flow structure

The aim of this paper is to compare the complexity of three simple sort algorithm; selection sort algorithm, bubble sort algorithm, and insertion sort algorithm. The measurement of the complexity is based on control flow structure and time processing. The control flow structure is illustrated into flowgraph and measured by number of out-degree and number of in-degree. The algorithm is coded in C programming language. The sorting experiment uses four data sets: 100,000 random words, 50,000 random words, 100,000 random integer numbers, and 50,000 random integer numbers to measure the time processing. The result of the measurement explains that the bubble sort algorithm has the complexity more than others.
DNA-Based Identification of a Carbonized Victim by Kinship Analysis.

BACKGROUND Our study will present the DNA identification of a carbonized victim using the DNA genotyping and by comparing the victim's DNA genotype with his parents' genotypes. METHODS Blood obtained from the heart chambers was used for the identification of the carbonized body's genotype. Biological samples were also obtained by buccal swabs from his biological parents. We used an ABI 7500 real-time PCR system for quantification and a ProFlex PCR System to amplify. PCR products were separated on an ABI 3500 genetic analyser and identified using GeneMapper ID-X vers. 1.4 software. RESULTS We obtained the three DNA genotypes (mother, father, and carbonized victim). Using maternity and paternity DNA testing we established that the victim's genetic profile matched the DNA profiles of his biological parents. The probability of maternity (PM) and probability of paternity (PP) were of 99.99999% for each of the parents. CONCLUSIONS Body fluids (blood, saliva) represent a better source for DNA compared to hard tissue, and its processing times are shorter than those for bone or teeth.
Understanding the Relationships among Phytoplankton, Benthic Macroinvertebrates, and Water Quality Variables in Peri‐Urban River Systems

In this article, using the Hawkesbury‐Nepean River as a case study, the spatial and temporal trends of water quality variables over three sampling surveys in a peri‐urban situation are examined for their effect on benthic macroinvertebrate communities and phytoplankton communities and whether phytoplankton and benthic macroinvertebrate species can be used as indicators for river health assessment. For this, the authors monitored the spatial and temporal difference of 10 water quality parameters: temperature, turbidity, pH, dissolved oxygen, electrical conductivity, oxidation reduction potential, total nitrogen, total phosphorus, manganese, and suspended solids. The variability in water quality parameters clearly indicated a complex pattern, depending on the season (interaction p = 0.001), which highlighted how the river condition is stressed at multiple points as a result of anthropogenic effects. In particular, the downstream locations indicated an accumulation of nutrients, the presence of increased sediments, and phytoplankton related variables such as total counts, bio‐volumes, chlorophyll‐a, and total phosphorus. The patterns of phytoplankton communities varied in a complex way depending on the season (interaction p = 0.001). Abundances of phytoplankton were also found in low concentrations where the water column is not severely disturbed by flow and tide. However, when the water clarity drops resulting from tidal cycles, inflows from tributaries, and intense boating activities, the phytoplankton abundances also increased considerably. On the other hand, benthic macroinvertebrates compositions were significantly different between locations (p = 0.001) with increased abundances associated with upstream sites. Aphanocapsa holsatica and chironomid larvae appeared as the important indicators for upstream and downstream site differences in water quality. Water temperature influenced the phytoplankton community pattern (ρw = 0.408), whereas pH influenced the benthic macroinvertebrate community pattern (ρw = 0.437). The findings of this study provide valuable insights into the interactions of water quality parameters on biotic assemblages and to the extent that benthic macroinvertebrates and phytoplankton assemblages are suitable as indicators for monitoring and assessing peri‐urban river health.
Psychiatric Consultation for Somatizing Patients in the Family Practice Setting: A Feasibility Study

Objective: The purpose of the study was to assess the feasibility of a psychiatric consultation intervention for somatizing patients in the family practice setting in terms of 1) patient compliance, 2) patient satisfaction, and 3) compliance and satisfaction of general practitioners (GPs). Method: In a period of nine months, forty-six patients were selected for psychiatric consultation in six solo family practices in a semi-urban area in the Netherlands. The consultation included an interview with the consulting psychiatrist, the patient, and the GP. A written summary of the consultation was provided to the GP and the patient. A booster session with a GP and psychiatrist was included to evaluate and reinforce the recommendations. Results: The majority of the selected patients agreed to participate after informed consent. An intervention was implemented containing interpersonal techniques, reattribution, clarification, and structuring. GP compliance with recommendations was 100 percent, patient compliance 75 percent. Conclusion: A standardized psychiatric consultation for somatizing patients in a family practice setting can be implemented. Several levels of implementation can be distinguished.
Dynamic Deployment and Optimization of Virtual Content Delivery Networks

Today, over-the-top video streaming is gaining a lot of popularity. In this respect, the virtual content delivery network (CDN) is perceived as a key enabler to circumvent the technical challenges faced by content providers to deliver high-quality content over the Internet. Here, the authors investigate how the two main actors of the video delivery chain--the CDN operator and the ISP--can benefit from network and server virtualization to negotiate dynamic service-level agreements that reduce CDN capital expenditures and operating expenses, while generating more revenue for the ISP. First, the authors present a dataset used to simulate dynamic distributed traffic consumption. Second, they discuss the steps required to deploy and operate a virtual CDN deployed on an ISP's network. Furthermore, they present evaluation results of the proposed solution, based on simple models. Lastly, they elaborate on operational parameters that are used to further optimize the solution. This article is part of a special issue on advancing multimedia distribution.

University of Texas at Dallas, Richardson, Texas Monash University, Monash Business School, Australia Curtin University, Curtin Business School, Australia Correspondence Riki Takeuchi, Naveen Jindal School of Management, University of Texas at Dallas, 800 West Campbell Rd, SM 43, Richardson, TX 75080-3021. Email: Riki.Takeuchi@utdallas.edu Using a sample composed of 701 food and beverage managers nested in 120 units and 40 Asian hotel properties, in the current study we investigated the effects of unit highperformance work system (HPWS) use and unit support climate on individual unit members' human resource outcomes (job performance behaviors: in-role and organizational citizenship behaviors). The results support the hypothesized relationships among unit HPWS use, unit support climate, individual affective commitment, and individual job performance behaviors. The current study's findings illuminate the ways (e.g., mediation and moderation) in which the unit support climate advances positive organizationally relevant individual-level human resource outcomes. Findings, implications, and limitations as well as avenues for future research are discussed.
Intergenerational Transmission of Education in China: New Evidence from the Chinese Cultural Revolution

This paper estimates the effect of parental education on children's education by using instruments generated by the Chinese Cultural Revolution, and further explores the mechanisms of this causal relationship. Several important findings stand out from our empirical analyses. We find a larger intergenerational persistence in education for higher level in urban areas but for a lower level of education in rural areas. The main results from instrumental variable estimation show that the nurture effect is larger and more significant for fathers than for mothers. A deeper investigation of the mechanism behind this nurture effect informs us that a father's education passes on to his children's education partly through the income channel. Another notable finding is that even after controlling for fathers’ income, parental education still has a significantly positive effect on children's education through the nurture effect. This indicates that beyond the income channel, there may exist other channels such as better home environment, which deserve to be explored in future research.
Effect of independent cycle crank training on running economy and VO2 max in distance runners

Wagner DR, Heath EM, Smith AW. Effect of Independent Cycle Crank Training on Running Economy and VO2 Max in Distance Runners. JEPonline 2013;16(1):1-9. The purpose of this study was to examine the changes in running economy and maximal oxygen consumption (VO2 max) of cross-country runners with cross-training on the PowerCranksTM. Seven men and 6 women completed 6 wks of stationary cycle ergometer training using either the PowerCranksTM or the standard cranks (control group). The subjects trained 3 d∙wk at 60 rev·min at 3 to 3.5 kg for 30 min, which increased to 40 min after the 3rd wk and 50 min after the 4th wk, with a 48-h minimum between training sessions. Pre-and post-running economy and VO2 max were measured. There were no significant differences in running economy or VO2 max after training in either the control or the PowerCranksTM group. Further, the difference in change scores for running economy between the PowerCranksTM (0.102 ± 0.101 L∙min) and the control (0.010 ± 0.108 L∙min) groups was not significant (P=0.15). Crosstraining for 6 wks with independent cycle cranks 3 d∙wk had no effect on the running economy or VO2 max of highly-trained collegiate distance runners.
Tom7 modulates the dynamics of the mitochondrial outer membrane translocase and plays a pathway‐related role in protein import.

The preprotein translocase of the outer mitochondrial membrane is a multi‐subunit complex with receptors and a general import pore. We report the molecular identification of Tom7, a small subunit of the translocase that behaves as an integral membrane protein. The deletion of TOM7 inhibited the mitochondrial import of the outer membrane protein porin, whereas the import of preproteins destined for the mitochondrial interior was impaired only slightly. However, protein import into the mitochondrial interior was strongly inhibited when it occurred in two steps: preprotein accumulation at the outer membrane in the absence of a membrane potential and subsequent further import after the re‐establishment of a membrane potential. The delay of protein import into tom7delta mitochondria seemed to occur after the binding of preproteins to the outer membrane receptor sites. A lack of Tom7 stabilized the interaction between the receptors Tom20 and Tom22 and the import pore component Tom40. This indicated that Tom7 exerts a destabilizing effect on part of the outer membrane translocase, whereas Tom6 stabilizes the interaction between the receptors and the import pore. Synthetic growth defects of the double mutants tom7delta tom20delta and tom7delta tom6delta provided genetic evidence for the functional relationship of Tom7 with Tom20 and Tom6. These results suggest that (i) Tom7 plays a role in sorting and accumulation of the preproteins at the outer membrane, and (ii) Tom7 and Tom6 perform complementary functions in modulating the dynamics of the outer membrane translocase.
Mapping the progress of social media research in hospitality and tourism management from 2004 to 2014

ABSTRACT One hundred and five articles on social media in hospitality and tourism during 2004–2014 were identified from three databases and seven journals. Seven dimensions were used for analysis. Results indicated that social media research in hospitality and tourism is in its early stages with two turning points. The number of articles rose dramatically in 2010 and unexpectedly dropped in 2014. Research gaps are apparent in several industry sectors in topics beyond online reviews and in research methods, where literature reviews suffer from small numbers and few prominent researchers. Implications and future research directions are also discussed.
Free Search Differential Evolution

Free Search Differential Evolution (FSDE) is a new, population-based meta-heuristic algorithm that is a hybrid of concepts from Free Search (FS), Differential Evolution (DE) and opposition-based learning. The performance of the proposed approach is investigated and compared with DE and one of the recent variants of DE when applied to ten benchmark functions. The experiments conducted show that FSDE provides excellent results with the added advantage of no parameter tuning.
