A Hermite‐Lobatto Pseudospectral Method for Optimal Control
Authors: Liu YuanBo , Zhu HengWei , Huang XiaoNian , Zheng GangTie 
Published: March 2014

AbstractA pseudospectral (PS) method based on Hermite interpolation and collocation at the Legendre‐Gauss‐Lobatto (LGL) points is presented for direct trajectory optimization and costate estimation of optimal control problems. A major characteristic of this method is that the state is approximated by the Hermite interpolation instead of the commonly used Lagrange interpolation. The derivatives of the state and its approximation at the terminal time are set to match up by using a Hermite interpolation. Since the terminal state derivative is determined from the dynamic, the state approximation can automatically satisfy the dynamic at the terminal time. When collocating the dynamic at the LGL points, the collocation equation for the terminal point can be omitted because it is constantly satisfied. By this approach, the proposed method avoids the issue of the Legendre PS method where the discrete state variables are over‐constrained by the collocation equations, hence achieving the same level of solution accuracy as the Gauss PS method and the Radau PS method, while retaining the ability to explicitly generate the control solution at the endpoints. A mapping relationship between the Karush‐Kuhn‐Tucker multipliers of the nonlinear programming problem and the costate of the optimal control problem is developed for this method. The numerical example illustrates that the use of the Hermite interpolation as described leads to the ability to produce both highly accurate primal and dual solutions for optimal control problems.

SUMMARYBuilding energy modeling (BEM) is an approach to model the energy usage in buildings for design and retrofit purposes. EnergyPlus is the flagship Department of Energy software that performs BEM for different types of buildings. The input to EnergyPlus can often extend in the order of a few thousand parameters that have to be calibrated manually by an expert for realistic energy modeling. This makes it challenging and expensive thereby making BEM unfeasible for smaller projects. In this paper, we describe the ‘Autotune’ research that employs machine learning algorithms to generate agents for the different kinds of standard reference buildings in the US building stock. The parametric space and the variety of building locations and types make this a challenging computational problem necessitating the use of supercomputers. Millions of EnergyPlus simulations are run on supercomputers that are subsequently used to train machine learning algorithms to generate agents. These agents, once created, can then run in a fraction of the time thereby allowing cost‐effective calibration of building models. Published 2014.

Anaplastic large‐cell lymphoma (ALCL) is a rare and newly described complication associated with breast implants. Patients often present with a peri‐implant effusion, which is amenable to fine‐needle aspiration. The laboratory handling of peri‐implant effusions for cytology and ancillary studies is as crucial as recognizing the characteristic cytology of ALCL.All cases of peri‐implant effusions were retrieved from the PathWest database between January 2003 and May 2013, yielding four cases of breast implant‐associated ALCL and six benign samples. The cytological features were evaluated and information from ancillary studies collated. Clinical and follow‐up histology was available in all cases.All ALCL cases contained highly atypical lymphoid cells including ‘hallmark' cells. In contrast, benign peri‐implant effusions showed a mixture of inflammatory cells, being either neutrophil‐rich (three cases) or lymphocyte‐rich (three cases). A CD30 positive, ALK1 negative immunophenotype was demonstrated in all cases on cell block immunohistochemistry. Flow cytometry and T‐cell receptor clonality studies confirmed aberrant T‐cell immunophenotype in four of four and clonally rearranged T‐cell receptor antigens in three of three cases. ALCL was identified in three of four subsequent capsulectomies. Staging confirmed disease limited to the capsular tissue or peri‐implant effusion in all cases. None of the six patients with benign peri‐implant effusions developed lymphoma during follow‐up.Cases of ALCL accounted for 40% of peri‐implant effusions received over a 10‐year period, indicating the rarity of these samples and the high likelihood of malignancy. Awareness of this entity and its presentation should allow for appropriate triage of these specimens and definitive diagnosis on effusion specimens. Diagn.

Power lines, roads, and avian nest survival: effects on predator identity and predation intensity
Authors: DeGregorio Brett A. , Weatherhead Patrick J. , Sperry Jinelle H. 
Published: March 2014

Abstract

Anthropogenic alteration of landscapes can affect avian nest success by influencing the abundance, distribution, and behavior of predators. Understanding avian nest predation risk necessitates understanding how landscapes affect predator distribution and behavior.

From a sample of 463 nests of 17 songbird species, we evaluated how landscape features (distance to forest edge, unpaved roads, and power lines) influenced daily nest survival. We also used video cameras to identify nest predators at 137 nest predation events and evaluated how landscape features influenced predator identity. Finally, we determined the abundance and distribution of several of the principal predators using surveys and radiotelemetry.

Distance to power lines was the best predictor of predator identity: predation by brown‐headed cowbirds (Molothrus ater), corvids (Corvus sp. and Cyanocitta cristata), racers (Coluber constrictor), and coachwhips (Masticophis flagellum) increased with proximity to power lines, whereas predation by rat snakes (Elaphe obsoleta) and raptors decreased. In some cases, predator density may reliably indicate nest predation risk because racers, corvids, and cowbirds frequently used power line right‐of‐ways.

Of five bird species with enough nests to analyze individually, daily nest survival of only indigo buntings (Passerina cyanea) decreased with proximity to power lines, despite predation by most predators at our site being positively associated with power lines. For all nesting species combined, distance to unpaved road was the model that most influenced daily nest survival. This pattern is likely a consequence of rat snakes, the locally dominant nest predator (28% of predation events), rarely using power lines and associated areas. Instead, rat snakes were frequently associated with road edges, indicating that not all edges are functionally similar.

Our results suggest that interactions between predators and landscape features are likely to be specific to both the local predators and landscape. Thus, predicting how anthropogenic changes to landscapes affect nesting birds requires that we know more about how landscape changes affect the behavior of nest predators and which nest predators are locally important.

Published: March 2014

AbstractSoyasaponins have been reported to promote various health functions. However, the total soyasaponin and soyasapogenol content in soy products and the daily intake remain to be fully elucidated. We developed a high‐performance liquid chromatography coupled with tandem mass spectrometric (HPLC–MS/MS) method to evaluate the content of group A and B soyasaponins and soyasapogenols. The total soyasaponin content was measured after pretreatment converted soyasaponins to soyasapogenols. The total soyasaponin content in soy foods was 200–1800 nmol g−1, although that of soy sauce was 2–7 nmol g−1. The soyasapogenol to total soyasaponin ratio was 30–50% in long‐term matured miso. The majority of the soyasapogenol detected was soyasapogenol B rather than soyasapogenol A, resulting in speculation that further steps are required to liberate aglycones from glycoside‐conjugated soyasaponins in soyasapogenol A. We estimated the daily intake of total soyasaponins and soyasapogenols by the Japanese, which was 50.3 and 0.59 μmol, respectively. The soyasapogenol content and the soyasapogenol to total soyasaponin ratio was considerably low in most soy products, except for long‐term maturated miso. The major source of the daily intake of soyasaponins and soyasapogenols were tofu and miso, respectively.

ABSTRACTResearch on early signs of autism in social interactions often focuses on infants’ motor behaviors; few studies have focused on speech characteristics. This study examines infant‐directed speech of mothers of infants later diagnosed with autism (LDA; n = 12) or of typically developing infants (TD; n = 11) as well as infants’ productions (13 LDA, 13 TD). Since LDA infants appear to behave differently in the first months of life, it can affect the functioning of dyadic interactions, especially the first vocal productions, sensitive to expressiveness and emotions sharing. We assumed that in the first 6 months of life, prosodic characteristics (mean duration, mean pitch, and intonative contour types) will be different in dyads with autism. We extracted infants’ and mothers’ vocal productions from family home movies and analyzed the mean duration and pitch as well as the pitch contours in interactive episodes. Results show that mothers of LDA infants use relatively shorter productions as compared to mothers talking to TD infants. LDA infants’ productions are not different in duration or pitch, but they use less complex modulated productions (i.e., those with more than two melodic modulations) than do TD. Further studies should focus on developmental profiles in the first year, analyzing prosody monthly.

Published: March 2014

ABSTRACTThe aim of this pilot study was to investigate the relationship between maternal insightfulness and sensitivity and subsequent infant attachment security and disorganization in clinically depressed and nonclinical mother–infant groups. Nineteen depressed mothers with infants ages 3 to 11 months participated in this study. Twenty nonclinical mother–infant dyads were matched to the clinical sample according to infant sex and age. Maternal depression was assessed using the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (American Psychiatric Association, 1994), insightfulness using the Insightfulness Assessment (IA), and sensitivity using the Maternal Sensitivity Scales (M.D.S. Ainsworth, 1969). IA classifications and subscales were considered separately. Later infant attachment was assessed by the Strange Situation Procedure (M.D.S. Ainsworth, M.C. Blehar, E. Waters, & S. Wall, 1978). Depressed mothers tended to have less securely attached children than did nonclinical mothers. Within the clinical sample, the insightfulness categories correlated slightly moderately with attachment security, but were not related to attachment disorganization. Within the nonclinical sample, the IA categories were slightly moderately associated with attachment security and with disorganization. On IA subscales, relationship patterns differed in clinically depressed and nonclinical mother–infant dyads. These findings provide the first evidence of the predictive power of the IA categorization and subscales on subsequent infant attachment. They also may allow the development of different foci of intervention for enhancing insightful caregiving.
Environmental E‐Books and Green Goals

Published: March 2014

AbstractPre‐service teachers collaborated with 6th grade students to audit a College of Education building looking for possibilities to “go green.” The student/teacher teams developed an e‐book collection of project descriptions, completed budgets, estimated timelines, and sustainability requirements for the university to consider. The e‐books also included short films in which the students promoted their ideas for green awareness. In this project, flipping instructional spaces and real‐izing the curriculum created new possibilities for student‐led inquiry. In other words, literacy in the service of communicating meaningful messages, rather than literacy for literacy's sake, created a current of intent in which the students learned genres to achieve their green goals and the teachers learned how to develop authentic tasks and texts to develop students' expertise.
Cosmopolitan Literacies of Belonging in an After‐school Program With Court‐Involved Youths

Published: March 2014

AbstractThis article focuses on the concept of belonging as an embodied practice that is expressed by adolescents in multimodal ways and that can be nurtured inside and also beyond schools, such as within afterschool programs. We explore belonging in an afterschool program designed for court‐involved youth. Our research is theoretically framed by educational cosmopolitanism and multimodal literacy and we situate our analysis within a discussion of cosmopolitan literacies of belonging. The research reported in this article is part of an ongoing, multi‐year study, and our initial analyses suggest that youth seek out and create opportunities to experience and communicate a sense of belonging through play, in fleeting moments, during structured curricular moments, and through both verbal and non‐verbal modes. Our article concludes with recommendations for how practitioners might build on adolescents’ cosmopolitan literacies of belonging within institutional contexts.

AbstractWe examined the effects of the microenvironment on vascular differentiation of murine cardiovascular progenitor cells (CPCs). We isolated CPCs and seeded them in culture exposed to the various extracellular matrix (ECM) proteins in both two‐dimensional (2D) and 3D culture systems. To better understand the contribution of the microenvironment to vascular differentiation, we analyzed endothelial and smooth muscle cell differentiation at both day 7 and day 14. We found that laminin and vitronectin enhanced vascular endothelial cell differentiation while fibronectin enhanced vascular smooth muscle cell differentiation. We also observed that the effects of the 3D electrospun scaffolds were delayed and not noticeable until the later time point (day 14), which may be due to the amount of time necessary for the cells to migrate to the interior of the scaffold. The study characterized the contributions of both ECM proteins and the addition of a 3D culture system to continued vascular differentiation. Additionally, we demonstrated the capability bioengineer a CPC‐derived vascular graft. © 2014 Wiley Periodicals, Inc. J Biomed Mater Res Part B: Appl Biomater, 102B: 1730–1739, 2014.
REKINDLE: Robust extraction of kurtosis INDices with linear estimation

Published: March 2014

PurposeRecent literature shows that diffusion tensor properties can be estimated more accurately with diffusion kurtosis imaging (DKI) than with diffusion tensor imaging (DTI). Furthermore, the additional non‐Gaussian diffusion features from DKI can be sensitive markers for tissue characterization. Despite these benefits, DKI is more susceptible to data artifacts than DTI due to its increased model complexity, higher acquisition demands, and longer scanning times. To increase the reliability of diffusion tensor and kurtosis estimates, we propose a robust estimation procedure for DKI.MethodsWe have developed a robust and linear estimation framework, coined REKINDLE (Robust Extraction of Kurtosis INDices with Linear Estimation), consisting of an iteratively reweighted linear least squares approach. Simulations are performed, in which REKINDLE is evaluated and compared with the widely used RESTORE (Robust EStimation of Tensors by Outlier REjection) method.ResultsSimulations demonstrate that in the presence of outliers, REKINDLE can estimate diffusion and kurtosis indices reliably and with a 10‐fold reduction in computation time compared with RESTORE.ConclusionWe have presented and evaluated REKINDLE, a linear and robust estimation framework for DKI. While REKINDLE has been developed for DKI, it is by design also applicable to DTI and other diffusion models that can be linearized. Magn Reson Med 73:794–808, 2015. © 2014 Wiley Periodicals, Inc.

AbstractIndium tin oxide (ITO) transparent electrodes formed on II‐VI compound semiconductor optical devices on InP substrates were characterized. Two kinds of ZnCdSe/BeZnTe p‐n diode devices with a different p‐contact layer (i.e., p‐ZnTe and p‐ZnSeTe layers) were prepared to investigate more suitable p‐contact material for ITO electrodes on the II‐VI devices. Thin ITO layers were deposited on the devices by magnetron sputtering. From injection current density versus applied voltage (J‐V) characteristics, the turn‐on voltage of the ZnTe contact device was found to be lower than that of the ZnSeTe contact device by about 2 V. The J‐V characteristic of the ZnTe device was comparable to that of the device with Au electrodes on the p‐contact instead of ITO. Using ITO electrodes, ZnCdSe/BeZnTe erlattice photovoltaic devices with ZnTe and ZnSeTe p‐contact layers were fabricated. The devices were characterized under 1.5 AM illumination at room temperature. The J‐V characteristics showed that the device performances of the ZnTe contact device were almost erior to those of the ZnSeTe device. Open‐circuit voltage, short‐circuit current density, fill factor, and maximum conversion efficiency of the ZnTe device were 0.90 V, 4.7 A/cm2, 0.35, and 1.5%, respectively.

AbstractNitrogen‐doped (N‐doped) ZnO single crystals were prepared by the hydrothermal method. Resistivity of the N‐doped ZnO single crystal was 107–108 Ωcm, which was about 104‐times higher than that of the non‐doped ZnO single crystal. Photocurrent of the O‐face was larger than that of the Zn‐face and maximum photoresponsivity was about 4×103 A/W. Photosensitivity (light/dark current ratio) of the Zn‐face of the N‐doped single crystal was 4×104 under illumination of 15 µW/cm2, but that of the O‐face was about 7×104. The visible rejection ratio (UV/visible photocurrent ratio) was over 104 for the Zn‐face of the N‐doped ZnO single crystal. Time response of the photocurrent of the N‐doped ZnO single crystal was remarkably improved compared to that of the non‐doped ZnO single crystal. An N‐doped ZnO single crystal is useful as a material for photoconductive type UV sensors. (© 2014 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Published: March 2014

AbstractThe first light emitting diodes using nitrogen doped ZnO nanoparticles (NPs) coated film on GZO have been demonstrated. This device showed diode characteristics in I ‐V measurement and near band edge UV electroluminescence (EL) was observed at the forward voltage of over 3 V. Only near band edge emission was observed in the EL spectrum while PL spectrum has a defect peak. This indicates the efficient exciton recombination was occurred due to the injection of high concentration holes and electrons into the NPs. (© 2014 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
