Study of Stability of Precise Tiled-grating Device

To satisfy the high-stability requirement of a tiled grating, we have analyzed and optimized the stability of a newly designed precise tiledgrating device considering three aspects: structure design, transmission chain, and control algorithms. The main structure of the device is changed from a parallel-board structure to a new tetrahedral brace design, enhancing the overall vibration stability; during the analysis of the transmission chain, the adjustment accuracy and stability of the device were ensured by slowing the growth of the error transmission factor; and for the optimization analysis of the PID control algorithms, we adopted a latch compensation method to avoid the saturated loss and a four-point central difference method to avoid the disturbances, thus enhancing the stability control of the device. To test the stability of the device, an optical experiment with a reference spot was designed. The experimental results showed that over 380 s, the ambient excitation response was always within an acceptable range. The average deflections about the X axis and Y axis are 0.243 and 0.00146 μrad, respectively, which satisfy the stability requirement.
Voltage control by means of smart transformer in medium voltage feeder with distribution generation

The integration of uncontrolled distributed generation (DG), like photovoltaic and wind turbines, and the growing amount of connected loads in the medium voltage (MV) grids have worsened the voltage variability, and in extreme cases violating the voltage limits. New mechanism and control action for supporting the voltage must be adopted, due to the unpredictability of these resources. The power electronics-based smart transformer (ST) can provide ancillary services to the distribution grid without the installation of additional devices, and among them the voltage and reactive power control. This paper illustrates, through simulation in PSCAD, the ST capability in controlling the voltage profile within the safe operation limits.
Galactose oxidation using 13C in healthy and galactosemic children

Galactosemia is an inborn error of galactose metabolism that occurs mainly as the outcome of galactose-1-phosphate uridyltransferase (GALT) deficiency. The ability to assess galactose oxidation following administration of a galactose-labeled isotope (1-13C-galactose) allows the determination of galactose metabolism in a practical manner. We aimed to assess the level of galactose oxidation in both healthy and galactosemic Brazilian children. Twenty-one healthy children and seven children with galactosemia ranging from 1 to 7 years of age were studied. A breath test was used to quantitate 13CO2 enrichment in exhaled air before and at 30, 60, and 120 min after the oral administration of 7 mg/kg of an aqueous solution of 1-13C-galactose to all children. The molar ratios of 13CO2 and 12CO2 were quantified by the mass/charge ratio (m/z) of stable isotopes in each air sample by gas-isotope-ratio mass spectrometry. In sick children, the cumulative percentage of 13C from labeled galactose (CUMPCD) in the exhaled air ranged from 0.03% at 30 min to 1.67% at 120 min. In contrast, healthy subjects showed a much broader range in CUMPCD, with values from 0.4% at 30 min to 5.58% at 120 min. The study found a significant difference in galactose oxidation between children with and without galactosemia, demonstrating that the breath test is useful in discriminating children with GALT deficiencies.
EVOLUTIONARY HISTORY OF CONTAGIOUS ASEXUALITY IN DAPHNIA PULEX

Abstract Asexual taxa are short-lived, suggesting that transitions to asexuality represent evolutionary dead-ends. However, with high rates of clonal origin and coexistence of asexuals and sexuals via selective asymmetries, asexuality may persist in the long term as a result of a dynamic equilibrium between clonal origin and extinction. Few such systems have been studied in detail. Here, we investigate the evolutionary history of asexual lineages of Daphnia pulex, which are derived from sexual relatives via the inheritance of a dominant female-limited meiosis-suppressing locus and inhabit ponds throughout northeastern North America (NA). Our extensive sampling and subsequent phylogenetic analysis using mitochondrial sequence data reveals a young and genetically diverse asexual assemblage, reflecting high rates of clonal origin due to the contagious nature of asexuality. Yet, asexuality is restricted to two phylogroups (B and C) with historical and/or present associations with northeastern NA and is absent from a northwestern phylogroup (A), supporting a recent northeastern origin of asexuality in this species. Furthermore, macrogeographic patterns of genetic variability indicate that phylogroups B and C recolonized northeastern NA from opposite directions, yet their presently overlapping geographic distributions are similarly divided into an eastern asexual and a western sexual region. We attribute these patterns to a recent contagious spread of asexuality from a northeastern source. If environment-mediated selective asymmetries play no significant role in determining the outcome of competitive interactions between sexuals and asexuals, regions of contact may be setting the stage for continued asexual conquests.
Rodent Models of Invasive Aspergillosis due to Aspergillus fumigatus: Still a Long Path toward Standardization

Invasive aspergillosis has been studied in laboratory by the means of plethora of distinct animal models. They were developed to address pathophysiology, therapy, diagnosis, or miscellaneous other concerns associated. However, there are great discrepancies regarding all the experimental variables of animal models, and a thorough focus on them is needed. This systematic review completed a comprehensive bibliographic analysis specifically-based on the technical features of rodent models infected with Aspergillus fumigatus. Out the 800 articles reviewed, it was shown that mice remained the preferred model (85.8% of the referenced reports), above rats (10.8%), and guinea pigs (3.8%). Three quarters of the models involved immunocompromised status, mainly by steroids (44.4%) and/or alkylating drugs (42.9%), but only 27.7% were reported to receive antibiotic prophylaxis to prevent from bacterial infection. Injection of spores (30.0%) and inhalation/deposition into respiratory airways (66.9%) were the most used routes for experimental inoculation. Overall, more than 230 distinct A. fumigatus strains were used in models. Of all the published studies, 18.4% did not mention usage of any diagnostic tool, like histopathology or mycological culture, to control correct implementation of the disease and to measure outcome. In light of these findings, a consensus discussion should be engaged to establish a minimum standardization, although this may not be consistently suitable for addressing all the specific aspects of invasive aspergillosis.
Predictive Validity of the Matrix Analogies Test-Short Form

This study examined the predictive validity of the Matrix Analogies Test Short Form (MAT-SF), a recently available nonverbal test of cognitive ability, with the Comprehensive Test of Basic Skills (CTBS). There were no significant differences, as expected, between the CTBS composite scores but the MAT-SF score was found to be significantly lower than all of the CTBS composite scores. This finding is similar to ones reported in the literature with other academic tests for samples of regular education children. The MAT-SF correlated significantly with all areas of the CTBS composite and spelling scores. The findings of this study and suggestions for the use of the MAT-SF as a screening instrument in the assessment of exceptional children are discussed.
Moral Development Among Court-Ordered Batterers: Evaluating the Impact of Treatment

Objective: This study evaluated the impact of a standard cognitive-behavioral group treatment program on altering levels of moral reasoning among court-ordered batterers. Method: The study employed a nonequivalent control group design in examining the moral reasoning level of 32 adult men, 84% African American, court ordered into a standard group treatment program for domestic violence offenders. Results: Analysis of the pretest data indicated that the entire sample of batterers was employing a level of moral reasoning two standard deviations lower than adults in general. In addition, analysis of the posttest data demonstrated that there was no significant increase in moral reasoning at the conclusion of the treatment program. These findings indicated that the current treatment program was ineffective in influencing moral reasoning. Conclusion: Implications of the findings for providing a culturally relevant theoretical framework to approach intervention with court-ordered batterers are explored and discussed.
Normal mode analysis on storm events in the Gulf of Tonkin and Leyte Gulf

In this study, we have applied normal mode analysis on recent past storm events in the Gulf of Tonkin and the Leyte Gulf. The normal modes for each location are obtained from the previously developed unstructured normal mode decomposition solver based on the finite element method. The analysis of the two recent past storm events using the normal modes derived from the solver has been investigated in these two locations. The first event is tropical cyclone NARI (2013) in the Gulf of Tonkin, Vietnam and the second one is the super typhoon HAIYAN (2013) in the Leyte Gulf, the Philippines. Apart from obtaining the site-specific storm hazard summary through the normal mode shape, the study also aims to gain a deeper understanding on how normal modes contributed to the overall surge from the analysis of these past storm events.
Learning From Web Videos for Event Classification

Traditional approaches for classifying event videos rely on a manually curated training data set. While this paradigm has achieved excellent results on benchmarks, such as TrecVid multimedia event detection (MED) challenge data sets, it is restricted by the effort involved in careful annotation. Recent approaches have attempted to address the need for annotation by automatically extracting images from the web, or generating queries to retrieve videos. In the former case, they fail to exploit additional cues provided by video data, while in the latter, they still require some manual annotation to generate relevant queries. We take an alternate approach in this paper, leveraging the synergy between visual video data and the associated textual metadata, to learn event classifiers without manually annotating any videos. Specifically, we first collect a video data set with queries constructed automatically from textual description of events, prune irrelevant videos with text and video data, and then learn the corresponding event classifiers. We evaluate this approach in the challenging setting where no manually annotated training set is available, i.e., EK0 in the TrecVid challenge, and show state-of-the-art results on MED 2011 and 2013 data sets.
Behavioral implications of adaption-innovation: I. Managerial effectiveness as a function of sex differences in adaption-innovation

We developed 3 studies to investigate the relationship between effective management and the positions of male and female managers on Kirton’s cognitive style dimension of adaption (doing things better) vs. innovation (doing things differently). Both sexes equated innovation with effective male management and adaption with effective female management. The role in management style of characteristic sex-specific differences in adaption-innovation is discussed.
Draft Genome Sequences of Two Lipopeptide-Producing Strains of Bacillus methylotrophicus

ABSTRACT Bacillus methylotrophicus is implicated in phytostimulation and disease suppression of agricultural and bioenergy crops. Here, we present the genome sequences of B. methylotrophicus strains B26 and OB9. Their assembly resulted in 26 and 24 contigs, respectively. These strains are well suited for comparative genomics studies and the evaluation of commercially valuable biomolecular compounds.
MoteSec-Aware: A Practical Secure Mechanism for Wireless Sensor Networks

Ensuring the security of communication and access control in Wireless Sensor Networks (WSNs) is of paramount importance. In this paper, we present a security mechanism, MoteSec-Aware, built on the network layer for WSNs with focus on secure network protocol and data access control. In the secure network protocol of MoteSec-Aware, a Virtual Counter Manager (VCM) with a synchronized incremental counter is presented to detect the replay and jamming attacks based on the symmetric key cryptography using AES in OCB mode. For access control, we investigate the Key-Lock Matching (KLM) method to prevent unauthorized access. We implement MoteSec-Aware for the TelosB prototype sensor platform running TinyOS 1.1. 15, and conduct field experiments and TOSSIM-based simulations to evaluate the performance of MoteSec-Aware. The results demonstrate that MoteSec-Aware consumes much less energy, yet achieves higher security than several state-of-the-art methods.
A Social Welfare Organizer in Sixteenth-Century New Spain: Don Vasco de Quiroga, First Bishop of Michoacán

No tourist who visits central Mexico will fail to pay a visit to the world-famous lake of Pátzcuaro. This beautiful and placid lake, with the several islands which dot its surface and the surrounding hills that frame it, formed, in olden times, the hub of the Michoacán Kingdom. Even today, it is the main habitat of the peaceloving Tarascan Indians who cluster around it and, partly at least, live on its abundant fish. An ancient author tells us that the word Michoacán means “fishing place,” and that the main occupation of the early Indians was the mild art of fishing, so opposed to the war-like activities of their neighbors to the east, the cruel Aztecs.
Transactions Papers source-optimized channel coding for digital transmission channels

We present a new class of nonlinear block codes called source-optimized channel codes (SOCCs), which are particularly designed for parametric source encoding of speech, audio, and video. In contrast to conventional channel codes, the new codes are not optimized for minimizing residual bit-error rate, but maximizing the signal-to-noise ratio of transmitted source codec parameters. The decoding of SOCCs is not based on bit-error correction, but on parameter estimation. We compare SOCCs with other approaches to joint source/channel coding such as channel-optimized vector quantization, channel-constrained vector quantization, unequal error protection, and source-controlled channel decoding. In terms of performance, SOCCs show better robustness if under channel mismatch conditions. For real-world applications, SOCCs are attractive, since the separation of source and channel codec is preserved.
Mercury: a wearable sensor network platform for high-fidelity motion analysis

This paper describes Mercury, a wearable, wireless sensor platform for motion analysis of patients being treated for neuromotor disorders, such as Parkinson's Disease, epilepsy, and stroke. In contrast to previous systems intended for short-term use in a laboratory, Mercury is designed to support long-term, longitudinal data collection on patients in hospital and home settings. Patients wear up to 8 wireless nodes equipped with sensors for monitoring movement and physiological conditions. Individual nodes compute high-level features from the raw signals, and a base station performs data collection and tunes sensor node parameters based on energy availability, radio link quality, and application specific policies. Mercury is designed to overcome the core challenges of long battery lifetime and high data fidelity for long-term studies where patients wear sensors continuously 12 to 18 hours a day. This requires tuning sensor operation and data transfers based on energy consumption of each node and processing data under severe computational constraints. Mercury provides a high-level programming interface that allows a clinical researcher to rapidly build up different policies for driving data collection and tuning sensor lifetime. We present the Mercury architecture and a detailed evaluation of two applications of the system for monitoring patients with Parkinson's Disease and epilepsy.
Analysis of functional divergence within two structurally related glycoside hydrolase families

Two glycoside hydrolase (GH) families were analyzed to detect the presence of functional divergence using the program DIVERGE. These two families, GH7 and GH16, each contain members related by amino acid sequence similarity, retaining hydrolytic mechanisms, and catalytic residue identity. GH7 and GH16 comprise GH Clan B, with a shared β‐jelly roll topology and mechanism. GH7 contains fungal cellobiohydrolases and endoglucanases and is divided into five main subfamilies, four of the former and one of the latter. Cluster comparisons between three of the cellobiohydrolase subfamilies and the endoglucanase subfamily identified specific amino acid residues that play a role in the functional divergence between the two enzyme types. GH16 contains subfamilies of bacterial agarases, xyloglucosyl transferases, 1,3‐β‐D‐glucanases, lichenases, and other enzymes with various substrate specificities and product profiles. Four cluster comparisons between these four main subfamilies again have identified amino acid residues involved in functional divergence between the subfamilies. © 2009 Wiley Periodicals, Inc.

Resting regional cerebral blood flow and gambling task performance in cocaine-dependent subjects and healthy comparison subjects.

OBJECTIVE Orbitofrontal cortex regional cerebral blood flow (rCBF) is lower in cocaine-dependent subjects than in non-cocaine-dependent subjects. Performance on the Gambling Task, a test of decision making, is a putative correlate of orbitofrontal cortex activity and is reportedly impaired in drug-dependent subjects. The authors tested the hypothesis that lower Gambling Task scores would be associated with lower resting orbitofrontal cortex rCBF in cocaine-dependent subjects. METHOD Fifteen healthy comparison subjects and 13 abstinent cocaine-dependent subjects underwent resting single photon emission computed tomography to measure rCBF, after which they completed the Gambling Task. RESULTS Resting anterior cingulate and left dorsolateral prefrontal cortex rCBF significantly correlated with performance on the Gambling Task, but orbitofrontal cortex rCBF did not. Left dorsolateral prefrontal cortex rCBF was lower in the cocaine-dependent subjects than in the comparison subjects. CONCLUSIONS Resting anterior cingulate and dorsolateral prefrontal cortex rCBF is significantly related to decision making, as assessed by the Gambling Task.
Combining haptic sensing with safe interaction

We propose a solution which combines haptic sensing with safe interaction, at low cost. Contact locations are made through a flexible sheet of tactile binary switch matrix. This sheet covers the surface of a rigid bumper module assembled to the robot's basic link through a distributed pressure sensing units. Combination of location and force provides the haptic sensing module. The haptic system is covered with a flexible outer material which role is to absorb contact impacts and to cast local surface profile on which the robot can take support. This overall system allows having a combined haptic sensing with safe and robust physical interaction with both the environment and the human using active compliance. We discuss the benefit of such a simple and modular concept and present how to design the cover material. A simple prototype is realized and experienced.
Radiobiological evaluation of simultaneously dose-escalated versus non-escalated intensity-modulated radiation therapy for patients with upper thoracic esophageal cancer

Objective To compare the radiobiological response between simultaneously dose-escalated and non-escalated intensity-modulated radiation therapy (DE-IMRT and NE-IMRT) for patients with upper thoracic esophageal cancer (UTEC) using radiobiological evaluation. Methods Computed tomography simulation data sets for 25 patients pathologically diagnosed with primary UTEC were used in this study. DE-IMRT plan with an escalated dose of 64.8 Gy/28 fractions to the gross tumor volume (GTV) and involved lymph nodes from 25 patients pathologically diagnosed with primary UTEC, was compared to an NE-IMRT plan of 50.4 Gy/28 fractions. Dose-volume metrics, tumor control probability (TCP), and normal tissue complication probability for the lung and spinal cord were compared. In addition, the risk of acute esophageal toxicity (AET) and late esophageal toxicity (LET) were also analyzed. Results Compared with NE-IMRT plan, we found the DE-IMRT plan resulted in a 14.6 Gy dose escalation to the GTV. The tumor control was predicted to increase by 31.8%, 39.1%, and 40.9% for three independent TCP models. The predicted incidence of radiation pneumonitis was similar (3.9% versus 3.6%), and the estimated risk of radiation-induced spinal cord injury was extremely low (<0.13%) in both groups. Regarding the esophageal toxicities, the estimated grade ≥2 and grade ≥3 AET predicted by the Kwint model were increased by 2.5% and 3.8%. Grade ≥2 AET predicted using the Wijsman model was increased by 14.9%. The predicted incidence of LET was low (<0.51%) in both groups. Conclusion Radiobiological evaluation reveals that the DE-IMRT dosing strategy is feasible for patients with UTEC, with significant gains in tumor control and minor or clinically acceptable increases in radiation-induced toxicities.
Numerical Computation of the Lognormal Sum Distribution

This paper develops highly accurate numerical techniques for evaluating the mgf/ chf of a single lognormal variable and for computing the lognormal sum cdf. Complex integration techniques based on the steepest-descent integration are thus developed for evaluating the lognormal mgf/ chf. The saddlepoint of the integrand is explicitly expressed using the Lambert-W function. The optimal steepest-descent contour passing through the saddlepoint is then derived. Even a simple mid-point-rule-based integration technique can be used along this contour to evaluate the mgf/ chf at extremely high precision. A highly efficient, extremely accurate numerical method is then developed for evaluating the cdf of sum of independent lognormal variables. The cdf is expanded as an alternating series, on which the Epsilon algorithm for convergence acceleration is applied. This reduces the computational load significantly.
Clinicians' Judgments of Mental Health: A Proposed Scale

Introduction and Aims The concept of "mental health" has become current in the everyday thinking of clinicians despite its global and diversely defined character. The members of the Psychotherapy Research Project of The Menninger Foundation wanted to know whether this concept had enough tangibility and unity of reference to be reliably judged along a single continuum by experienced observers. The vast literature does not deal extensively with this apparently simple question. Most contributors have worked on problems of definition (e.g., Senn, 20 Mayman 15 ), although a small but expanding number of attempts have been made to measure specific criteria of health Lorr, 10 Rogers and Dymond, 18 Jahoda, 8 Kelman and Parloff, 9 Parloff 17 ). * We came to this question in the early phases of the Psychotherapy Research Project 26 when a need was felt for a simple survey instrument to record shorthand judgments of
