ANTISYMMETRY AND WORD ORDER IN SERIAL CONSTRUCTIONS

Strict head-final surface order derives from underlying left-headedness in Ijo , a Niger-Congo language of Nigeria. A word order anomaly in Ijo SERIAL VERB CONSTRUCTIONS (SVCs) strongly suggests this, and left-to-right asymmetric c-command among internal arguments of SVCs confirms it. The anomaly is universal among surface right-headed languages with SVCs, indicating that deep left-headedness is universal, as antisymmetry theory predicts (Kayne 1994). Assuming complements are in Specs, and that a light verb v selects every VP (Chomsky 1999), I derive VOVO from OVOV by two instances of V-to-v movement. I argue for a nonuniform approach to SVCs, involving relations of both raising (Campbell 1989) and control (Collins 1997). Other aspects of SVC word order are predictable from a universal thematic hierarchy nontheme theme, and short scrambling (Takano 1998).*
Vertical integration of memristors onto foundry CMOS dies using wafer-scale integration

As Moore's law scaling approaches its physical limit, there is increased interest in memristors as a replacement to transistors in memory applications due to their smaller footprint and superior scaling characteristics. However, memristors are intrinsically two-terminal devices, requiring an underlying CMOS control interface for proper operation. Thus the integration of CMOS and memristors is essential to the development of memristor technology. Accordingly, hybrid configurations have been proposed that make use of the advantages of CMOS while utilizing a high density of memristors. However, memristor/CMOS hybrid fabrication is not trivial because high-density memories require memristor dimensions to be much smaller than those of the underlying CMOS. Additionally, memristors typically make use of materials not allowed in conventional CMOS fabrication. These issues point to a post-CMOS fabrication approach. An associated consideration for memristor/CMOS hybrid fabrication is the high cost of whole wafer fabrication. While whole wafer fabrication of memristors is viable for large volume markets, it is not a practical route for niche applications or research. While this suggests the use of CMOS dies, edge effects typically set the minimum processable die size, as in the case of edge beads, which limit the achievable resolution of devices. To address these issues, we present a hybrid integration approach for post-CMOS vertical integration of memristors that is independent of CMOS die size. Our approach enables the vertical integration of memristors with small foundry-fabricated dies using a waferscale integration scheme. We demonstrate this approach using a 2.2-mm × 3.2-mm CMOS die fabricated in a standard dualpoly, three-metal 0.5-μm technology process. We use solution-processed BCB as an adhesive to embed CMOS dies into silicon wafer handles, allowing for easy handling and compatibility with a variety of lithography techniques such as electron-beam, nanoimprint and photolithography. The process is compatible with spin-coated planarization layers, such as polyimide or BCB, if nanometer-scale roughness is desired. As a demonstration, vertically integrated Ag/SiO2/Pt switches were fabricated on CMOS using conventional photolithography techniques in a university cleanroom and tested through the CMOS circuitry. The measurements were compared to those of Ag/SiO2/Pt switches fabricated off-chip in a similar process and indicate that the memristor/CMOS hybrids were fully functional. We believe this hybrid approach will pave the way for hybrid CMOS-memristor chips, enabling applications from neuromorphic computing to high-density memories.
Comparison of 30% salicylic acid with Jessner's solution for superficial chemical peeling in epidermal melasma.

OBJECTIVE
To compare the efficacy and safety of Jessner's solution with 30% salicylic acid as superficial chemical peeling agents in treating epidermal melasma in Asian skin.


STUDY DESIGN
Double blind, randomized, interventional comparative study.


PLACE AND DURATION OF STUDY
Department of Dermatology, Combined Military Hospital, Malir Cantt, Karachi, from January to December 2004.


PATIENTS AND METHODS
Sixty consenting patients with epidermal melasma were randomly divided into two groups. Group A was treated with Jessner's solution and Group B with 30% salicylic acid. Baseline Melasma Area Severity Index (MASI) score was noted and peeling started at 2-weekly intervals. Sunscreen in morning and moisturizer at night were prescribed in all patients. MASI score and adverse effects were recorded biweekly. Treatment was stopped at 12 weeks and patients were followed-up at 4 weekly intervals for further 12 weeks. Final MASI score and adverse effects were noted at the end of follow-up period. Mean MASI scores were compared using paired sample t-test and one-way ANOVA.


RESULTS
Difference in baseline, treatment end and follow-up end MASI scores was not statistically significant between the two groups (p 0.54, 0.26, and 0.55 respectively). On the other hand, within group analysis of difference between pre and posttreatment MASI score was highly significant in both groups (p<0.0001). Adverse effects were mild and comparable in both groups.


CONCLUSION
Jessner's solution and 30% salicylic acid are equally effective and safe peeling agents for use in epidermal melasma in Asian skin.
Too Much Humanness for Human-Robot Interaction: Exposure to Highly Humanlike Robots Elicits Aversive Responding in Observers

People tend to anthropomorphize agents that look and/or act human, and further, they tend to evaluate such agents more positively. This, in turn, has motivated the development of robotic agents that are humanlike in appearance and/or behavior. Yet, some agents -- often those with highly humanlike appearances -- have been found to elicit the opposite, wherein they are evaluated more negatively than their less humanlike counterparts. These trends are captured by Masahiro Mori's uncanny valley hypothesis, which describes a (uncanny) valley in emotional responding - a switch from affinity to dislike - elicited by agents that are ``too humanlike'. However, while the valley phenomenon has been repeatedly observed via subjective measures, it remains unknown as to whether such evaluations reflect a potential impact to a person's behavior (i.e., aversion). We attempt to address this gap in the literature via a novel experimental paradigm employing both traditional subjective ratings, as well as measures of peoples' behavioral and phsyiological responding. The results show that not only do people rate highly humanlike robots as uncanny, but moreover, they exhibit greater avoidance of such encounters than encounters with less humanlike and human agents. Thus, the findings not only support Mori's hypothesis, but further, they indicate the valley should be taken as a serious consideration for peoples' interactions with humanlike agents.
Should obesity be a limiting factor for clozapine treatment?

OBJECTIVE
Clozapine is the first choice in drug-resistant schizophrenia but also causes important weight changes. This might discourage clinicians concerned about the risk of developing health problems. To assess this issue we measured change in body mass index (cBMI) induced by clozapine at 18 and 56 weeks.


METHODS
Baseline body weight and height were measured and weight weekly thereafter during the first 18 weeks of treatment. After that, measurements were made monthly. Steady clozapine dose, clozapine and norclozapine blood concentrations, concomitant medication, gender and age were recorded.


RESULTS
At 18 weeks (n=76) mean cBMI was 1.83 kg/m(2). Baseline BMI was inversely correlated with cBMI. At 56 weeks (n=57) cBMI was 2.67 kg/m(2) and was inversely correlated with basal BMI. Multiple regression analysis replicated the results. When split with BMI categories, obese patients had lesser risk for further weight gain.


CONCLUSIONS
Obesity should not discourage clinicians from starting clozapine in drug-resistant patients.

Association of physical activity with vascular endothelial function and intima-media thickness.

BACKGROUND
Impairment of vascular endothelial function and increased intima-media thickness (IMT) are important early steps in atherogenesis. Longitudinal data on the effect of physical activity on endothelial function and IMT in healthy adolescents are lacking. We investigated prospectively the association of leisure-time physical activity with endothelial function (brachial artery flow-mediated dilatation; FMD) and aortic IMT in adolescents.


METHODS AND RESULTS
FMD and IMT were measured with ultrasonography at 13 (n=553), 15 (n=531), and 17 (n=494) years of age in adolescents participating in a longitudinal atherosclerosis prevention study (Special Turku Coronary Risk Factor Intervention Project for Children). Mean aortic IMT, maximum FMD, and total FMD response (area under the dilatation curve 40 to 180 seconds after hyperemia) were calculated. Leisure-time physical activity was assessed with a questionnaire, and metabolic equivalent (MET) hours per week of leisure-time physical activity were calculated by multiplying weekly mean exercise intensity, duration, and frequency. Leisure-time physical activity was directly associated with endothelial function (P for maximum FMD=0.0021, P for total FMD response=0.0036) and inversely with IMT (P=0.011) after adjustment for age, sex, body mass index, high-density lipoprotein/total cholesterol, systolic blood pressure, and C-reactive protein and regarding FMD brachial artery diameter. Sedentary adolescents who increased their leisure-time physical activity from <5 to >5 (IMT) or >30 (maximum FMD) MET h/wk between 13 and 17 years of age had an increased maximum FMD (P=0.031) and decreased progression of IMT (P=0.047) compared with adolescents who remained sedentary. IMT progression was attenuated in persistently active adolescents compared with those who became sedentary (P=0.0072).


CONCLUSIONS
Physical activity is favorably associated with endothelial function and IMT in adolescents. Importantly, a moderate increase in physical activity is related to decreased progression of IMT. A physically active lifestyle seems to prevent the development of subclinical atherosclerotic vascular changes in healthy adolescents. Clinical Trial Registration- URL: http://www.clinicaltrials.gov.

QoS-Driven Self-Healing Web Service Composition Based on Performance Prediction

Web services run in a highly dynamic environment, as a result, the QoS of which will change relatively frequently. In order to make the composite service adapt to such dynamic property of Web services, we propose a self-healing approach for web service composition. Such an approach is an integration of backing up in selection and reselecting in execution. In order to make the composite service heal itself as quickly as possible and minimize the number of reselections, a way of performance prediction is proposed in this paper. On this basis, the self-healing approach is presented including framework, the triggering algorithm of the reselection and the reliability model of the service. Experiments show that the proposed solutions have better performance in supporting the self-healing Web service composition.
Gellan gum biosynthesis in Sphingomonas paucimobilis ATCC 31461: Genes, enzymes and exopolysaccharide production engineering

The commercial gelling agent, gellan, is an extracellular polysaccharide (EPS) produced by Sphingomonas paucimobilis ATCC 31461. In recent years, significant progress in understanding the relationship between gellan structure and properties and elucidation of the biosynthesis and engineering of this recent product of biotechnology has been made. This review focuses on recent advances in this field. Emphasis is given to identification and characterization of genes and enzymes involved, or predicted to be involved, in the gellan biosynthetic pathway, at the level of synthesis of sugar-activated precursors, of the repeat unit assembly and of gellan polymerization and export. Identification of several genes, biochemical characterization of the encoded enzymes and elucidation of crucial steps of the gellan pathway indicate that possibilities now exist for exerting control over gellan production at any of the three levels of its biosynthesis. However, a better knowledge of the poorly understood steps and of the bottlenecks and regulation of the pathway, the characterization of the composition, structure and functional properties of gellan-like polymers produced either by the industrial strain under different culture conditions or by mutants are still required for eventual success of the metabolic engineering of gellan production.

Presenteeism in the workplace : A review and research agenda

Presenteeism refers to attending work while ill. Although it is a subject of intense interest to scholars in occupational medicine, relatively few organizational scholars are familiar with the concept. This article traces the development of interest in presenteeism, considers its various conceptualizations, and explains how presenteeism is typically measured. Organizational and occupational correlates of attending work when ill are reviewed, as are medical correlates of resulting productivity loss. It is argued that presenteeism has important implications for organizational theory and practice, and a research agenda for organizational scholars is presented.

Optimizing pain management to facilitate Enhanced Recovery After Surgery pathways.

PURPOSE
The optimal management of postoperative pain using multimodal analgesia is a key component of Enhanced Recovery After Surgery (ERAS). Pain has adverse clinical implications on postoperative recovery, including prolonging the time to recovery milestones and length of hospital stay. Moreover, the ubiquity of opioids in postoperative analgesic regimens results in adverse effects, such as sedation, postoperative nausea and vomiting, urinary retention, ileus, and respiratory depression, which can delay discharge. Thus, multimodal analgesia, i.e., the use of more than one analgesic modality to achieve effective pain control while reducing opioid-related side effects, has become the cornerstone of enhanced recovery. The purpose of this review is to address the analgesic techniques used as part of multimodal analgesic regimens to optimize postoperative pain control and to summarize the evidence for their use in reducing opioid requirements and side effects.


PRINCIPAL FINDINGS
There is a wide variety of analgesic techniques available for multimodal postoperative analgesia. These modalities are divided into pharmacological and non-pharmacological techniques. Systemic pharmacological modalities involve opioids and non-opioids such as acetaminophen, non-steroidal anti-inflammatory drugs, N-methyl-D-aspartate receptor antagonists, anticonvulsants (e.g., gamma-aminobutyric acid analogues), beta-blockers, alpha-2 agonists, transient receptor potential vanilloid receptor agonists (capsaicin), and glucocorticoids. Other pharmacological modalities include central neuraxial techniques, surgical-site infiltration, and regional anesthesia. Evidence supports the use of these pharmacological techniques as part of multimodal analgesia, but each has its own advantages and specific safety profile, which highlights the importance of selecting the appropriate analgesics for each patient. Adjunctive non-pharmacological techniques include acupuncture, music therapy, transcutaneous electrical nerve stimulation, and hypnosis. There is mixed evidence regarding such techniques, although a lack of harm is associated with their use.


CONCLUSION
There are continuing advancements in multimodal analgesic techniques; however, postoperative pain in general continues to be undermanaged. Furthermore, a continuing challenge in multimodal pain research related to ERAS is the difficulty in carrying out randomized trials to determine the relative importance of any one component, including analgesia.
Use of the Pediatric Symptom Checklist in a low-income, Mexican American population.

OBJECTIVE
To evaluate the usefulness of the Pediatric Symptom Checklist (PSC) in identifying behavioral problems in low-income, Mexican American children.


DESIGN
A cross-sectional study design was used to examine the PSC as a screening test, with the Child Behavior Checklist (CBCL) as the criterion standard.


SETTING
The study was conducted at a health center in a diverse low-income community. Patients Eligible patients were children and adolescents, 4 to 16 years of age, who were seen for nonemergent, well-child care. Of 253 eligible children during a 9-month study period, 210 agreed to participate in the study. There was a 100% completion rate of the questionnaires. The average age of the children was 7.5 years, and 45% were female. Ninety-five percent of patients were of Hispanic descent (Mexican American); 86% of families spoke only Spanish. Socioeconomic status was low (more than three fourths of families earned <$20 000 annually).


RESULTS
The CBCL Total scale determined that 27 (13%) of the children had clinical levels of behavioral problems. With a cutoff score of 24, the PSC screened 2 (1%) of the 210 children as positive for behavioral problems. Using the CBCL as the criterion standard, the PSC sensitivity was 7.4%, and the specificity was 100%. Receiver operator characteristic analysis determined that a PSC cutoff score of 12 most correctly classified children with and without behavioral problems (sensitivity, 0.74; specificity, 0.94).


CONCLUSIONS
When using the PSC, a new cutoff score of 12 for clinical significance should be considered if screening low-income, Mexican American children for behavioral problems. Additional study is indicated to determine the causes of the PSC's apparently lower sensitivity in Mexican American populations.
Characterization of Coil Faults in an Axial Flux Variable Reluctance PM Motor

In recent years, variable reluctance (VR) and switch reluctance (SR) motors have been proposed for use in applications requiring a degree of fault tolerance. A range of topologies of brushless SR and VR permanent magnet (PM) motors are not susceptible to some types of faults, such as phase-to-phase shorts, and can often continue to function in the presence of other faults. In particular, coil winding faults in a single stator coil may have relatively little effect on motor performance, but may affect overall motor reliability, availability, and longevity. It is important to distinguish between, and characterize, various winding faults for maintenance and diagnostic purposes. These fault characterization and analysis results are a necessary first step in the process of motor fault detection and diagnosis for this motor topology. This paper examines rotor velocity damping due to stator winding turn-to-turn short faults in a fault-tolerant axial flux variable reluctance PM motor. In this type of motor, turn-to-turn shorts due to insulation failures have similar I-V characteristics to coil faults resulting from other problems, such as faulty maintenance or damage due to impact. In order to investigate the effects of such coil faults, a prototype axial flux variable reluctance PM motor was constructed. The motor was equipped with experimental fault simulation stator windings capable of simulating these and other types of stator winding faults. This paper will focus on two common types of winding faults and their effects on rotor velocity in this type of motor.
Dielectric response, functionality and energy storage in epoxy nanocomposites: Barium titanate vs exfoliated graphite nanoplatelets

Abstract Barium titanate/epoxy and exfoliated graphite nanoplatelets/epoxy nanocomposites were prepared and studied varying the filler content. Morphological characteristics were examined via scanning electron microscopy, while structural changes occurring in barium titanate as a function of temperature were investigated by means of X-ray diffraction. Broadband dielectric spectroscopy was employed for determining the dielectric response of the prepared systems. Based on the conducted analysis it was found that three relaxation processes are present in the spectra of the examined materials. From the slower to the faster one, these are interfacial polarization, glass to rubber transition of the polymer matrix, and rearrangement of polar side groups of the polymer chain. Systems' functionality and energy storing efficiency were assessed in terms of dielectric reinforcing function. Finally, the energy density of all systems was evaluated. Composite systems with embedded graphite nanoplatelets exhibit higher energy storing efficiency, while thermally induced structural changes in ferroelectric particles provide functional behavior to barium titanate composites.
A survey of document image word spotting techniques

Vast collections of documents available in image format need to be indexed for information retrieval purposes. In this framework, word spotting is an alternative solution to optical character recognition (OCR), which is rather inefficient for recognizing text of degraded quality and unknown fonts usually appearing in printed text, or writing style variations in handwritten documents. Over the past decade there has been a growing interest in addressing document indexing using word spotting which is reflected by the continuously increasing number of approaches. However, there exist very few comprehensive studies which analyze the various aspects of a word spotting system. This work aims to review the recent approaches as well as fill the gaps in several topics with respect to the related works. The nature of texts and inherent challenges addressed by word spotting methods are thoroughly examined. After presenting the core steps which compose a word spotting system, we investigate the use of retrieval enhancement techniques based on relevance feedback which improve the retrieved results. Finally, we present the datasets which are widely used for word spotting, we describe the evaluation standards and measures applied for performance assessment and discuss the results achieved by the state of the art. © 2017 Elsevier Ltd.
