Ultra-Thin Epitaxial Tungsten Carbide Schottky Contacts in 4H-SiC

We demonstrate the fabrication and characterization of epitaxial W2C Schottky contacts into 4H-SiC via sputtering deposition of ultra-thin W followed by thermal annealing. The alloying reaction occurs below 600 °C, yielding a stable layer up to 1200 °C. The epitaxial layer is hexagonal, unexpectedly forming W2C phase even at the lowest annealing temperature, which is predicted to occur at 1500 °C in bulk systems. Schottky contacts based on epitaxial W2C films exhibit smoother interface morphology, higher thermal stability, lower turn-ON voltage and about ~50% reduction in Schottky-contact resistance compared with thick Ti Schottky contacts.
Participant or zombie? Exploring the limits of the participatory politics framework through a failed youth participatory action project

ABSTRACT This article explores how “real life” stories of heroic participation might conform to, or challenge, hero myths. It involved engaging students of an urban high school in critiquing the hero myths of popular culture while also inviting them to tell and retell their own stories of participatory politics. The students' activities were followed over a period of an academic year as they worked through different ways of thinking about stories of heroic action and also created their own messages, reflecting their views, to motivate others to engage in action. Over that period, the stories they told deepened and developed. Ultimately, the political action in which the students chose to engage was frustrated, which provided an opportunity to explore the limits of the participatory politics framework.
Compact Rewriting for Existential Rules

Querying large databases while taking ontologies into account is currently a very active domain research. In this paper, we consider ontologies described by existential rules (also known as Datalog+/-), a framework that generalizes lightweight description logics. A common approach is to rewrite a conjunctive query w.r. t an ontology into a union of conjunctive queries (UCQ) which can be directly evaluated against a database. However, the practicability of this approach is questionable due to 1) the weak expressivity of classes for which efﬁcient rewriters have been implemented 2) the large size of optimal rewritings using UCQ. We propose to use semi-conjunctive queries (SCQ), which are a restricted form of positive existential formulas, and compute sound and complete rewritings, which are union of SCQ (USCQ). A novel algorithm for query rewriting, C OMPACT , is presented. It computes sound and complete rewritings for large classes of ontologies. First experiments show that USCQ are both efﬁ-ciently computable and more efﬁciently evaluable than their equivalent UCQ.
[Ultrasound-guided percutaneous microwave ablation in the treatment of diffuse adenomyosis].

OBJECTIVE To assess the feasibility of percutaneous microwave ablation in the treatment of diffuse adenomyosis. METHODS With a mean age of 39.2 years old, 16 patients with symptomatic adenomyosis underwent percutaneous microwave ablation (PMA). The symptoms included severe dysmenorrheal and anemia. The definite diagnosis was made by magnetic resonance (MR) imaging. Two microwave therapeutic antennas were inserted into the myometrium with adenomyosis. The microwave emission was seized when the ablated zone was over half of the total lesion. The complications, side effects and early therapeutic effects were observed during the period of treatment and at 3 and 6 months post-treatment. RESULTS The average ablation duration was 700 s. The average ablated area was 72% (range: 60% - 80%). None of the patients developed complications during and after ablation. Fifteen patients had normal menstrual onset during the month of receiving ablation and one case at Day 30. The amount of menstrual bleeding was less than that before treatment. Dysmenorrhea disappeared after treatment in 13 cases, relieved markedly in 2 and no improvement in 1. The endometrial ectopic growth was not observed after treatment. CONCLUSION The early clinical efficacy of PMA under ultrasound guidance is definite in the treatment of adenomyosis. The symptoms may be eliminated or effectively relieved after treatment. Easy to perform, minimal invasive and safe, the procedure of PMA is an effective therapeutic modality for adenomyosis with the preservation of uterus.
Reduced renal function after preeclampsia does not result from accelerated age‐dependent renal function loss

Preeclampsia is associated with later kidney disease. This study tested the hypothesis that the normal decline in renal function with age is more rapid in formerly preeclamptic women than in controls. Four groups were compared cross‐sectionally: young women with a history of preeclampsia (n = 34), young controls (n = 12), middle‐aged women with a history of preeclampsia (n = 22) and middle‐aged controls (n = 29). We measured blood pressure (semi‐automatic device), effective renal plasma flow (ERPF, para‐aminohippurate clearance), glomerular filtration rate (GFR, creatinine clearance) and cardiac output (Doppler echocardiography). ERPF was lower in both young and middle‐aged women with a history of preeclampsia relative to controls. The decrease in both GFR and ERPF with age was comparable in both groups. In conclusion, the lower renal function in middle‐aged formerly preeclamptic women does not result from accelerated age‐dependent renal function loss, but from an already reduced renal function relative to parous controls at young age.
Quantitative Fluorescence In Situ Hybridization (QFISH) of Telomere Lengths in Tissue and Cells

Telomeres are repetitive DNA sequences at the end of each chromosome that provide stability and prevent end‐to‐end chromosome fusions. In order to understand mechanisms responsible for telomere shortening, it is necessary to develop methods for accurate telomere length measurement that can be applied to archival and fresh tissue and cells. This unit describes in situ–based quantitative fluorescence in situ hybridization (QFISH) protocols using a fluorescence‐conjugated telomere probe (peptide nucleic acid, PNA) that stains telomeres proportionally to their length. These protocols can be used on formalin‐fixed paraffin‐embedded tissue, lightly fixed tissue, cells isolated from tissue, cultured cells, and agar‐embedded cells. The basic protocol for QFISH staining is modified to achieve excellent QFISH staining for a variety of cell preparations. Image‐analysis techniques to quantitate average telomere lengths from tissues and isolated stained cells are also described.
NGS-Based Genotyping, High-Throughput Phenotyping and Genome-Wide Association Studies Laid the Foundations for Next-Generation Breeding in Horticultural Crops

Demographic trends and changes to climate require a more efficient use of plant genetic resources in breeding programs. Indeed, the release of high-yielding varieties has resulted in crop genetic erosion and loss of diversity. This has produced an increased susceptibility to severe stresses and a reduction of several food quality parameters. Next generation sequencing (NGS) technologies are being increasingly used to explore “gene space” and to provide high-resolution profiling of nucleotide variation within germplasm collections. On the other hand, advances in high-throughput phenotyping are bridging the genotype-to-phenotype gap in crop selection. The combination of allelic and phenotypic data points via genome-wide association studies is facilitating the discovery of genetic loci that are associated with key agronomic traits. In this review, we provide a brief overview on the latest NGS-based and phenotyping technologies and on their role to unlocking the genetic potential of vegetable crops; then, we discuss the paradigm shift that is underway in horticultural crop breeding.
Modeling and measurement of capacitive and inductive bearing current in electrical machines

Bearing voltage is the votlage over bearings and end-to-end shaft voltage is the voltage between two ends of the machine shaft. They are all induced by inverter based systems and may cause severe bearing failures and electromagnetic interference (EMI) problems. In this paper a comprehensive high frequency (HF) model of an induction machine for electric vehicles up to 10 Mhz, which simultaneously calculates these two voltages, is established based on physical meaning and eddy-current model. The parasitic capacitances are calculated by 3D Finite Element Method (FEM) while other parameters are derived from impedance curves. The simulation results are close to the measured signals, which validates the model.
Prospective randomized comparison of wavefront-guided and conventional photorefractive keratectomy for myopia with the meditec MEL 70 laser.

PURPOSE To study refractive results and aberrometric changes in myopic patients treated with wavefront-guided photorefractive keratectomy (PRK) in comparison with standard PRK. METHODS Sixty eyes of 60 patients with myopic astigmatism were randomly divided into two groups. Group 1 included 30 eyes (mean spherical equivalent refraction -4.39 +/- 1.31 D; range -2.50 to -6.50 D) treated with wavefront-guided PRK using the WASCA workstation and the Asclepion Meditec flying spot MEL 70 excimer laser. Group 2 had 30 eyes (mean spherical equivalent refraction -4.33 +/- 1.22 D; range -2.50 to -6.50 D) that underwent conventional PRK using the same laser, and served as the control group. Wavefront analysis of high order aberrations was performed before and 6 months after surgery. RESULTS Postoperatively, wavefront error increased in both groups (5.0-mm wavefront aperture diameter). Six months after surgery, the eyes that received the WASCA ablation had a smaller increase in root-mean-square (RMS; 70% of increment) compared to the conventional PRK group (139% of increment) (P<.001). In the standard PRK group, all aberrations notably increased; in the wavefront-guided PRK group there was a smaller increase of trefoil and spherical aberrations (P<.001) and a decrease of coma aberrations (P<.001). The smaller increase of wavefront error in the wavefront-guided PRK group compared to the standard PRK group was more evident when preoperative RMS values were higher than 0.4 microm (P<.01). The visual parameters (spherical equivalent refraction, uncorrected and best spectacle-corrected visual acuity) did not show significant differences between the two groups. CONCLUSION Wavefront-guided PRK induced a smaller increase of postoperative wavefront-error compared to conventional PRK, particularly in patients with higher preoperative higher order aberrations.
Sentiment classification technology based on Markov logic networks

ABSTRACT With diverse online media emerging, there is a growing concern of sentiment classification problem. At present, text sentiment classification mainly utilizes supervised machine learning methods, which feature certain domain dependency. On the basis of Markov logic networks (MLNs), this study proposed a cross-domain multi-task text sentiment classification method rooted in transfer learning. Through many-to-one knowledge transfer, labeled text sentiment classification, knowledge was successfully transferred into other domains, and the precision of the sentiment classification analysis in the text tendency domain was improved. The experimental results revealed the following: (1) the model based on a MLN demonstrated higher precision than the single individual learning plan model. (2) Multi-task transfer learning based on Markov logical networks could acquire more knowledge than self-domain learning. The cross-domain text sentiment classification model could significantly improve the precision and efficiency of text sentiment classification.
Impact of a multidisciplinary vulvodynia program on sexual functioning and dyspareunia.

INTRODUCTION For many years, multidisciplinary approaches, which integrate psychological, physical, and medical treatments, have been shown to be effective for the treatment of chronic pain. To date, there has been anecdotal support, but little empirical data, to justify the application of this multidisciplinary approach toward the treatment of chronic sexual pain secondary to provoked vestibulodynia (PVD). AIM This study aimed to evaluate a 10-week hospital-based treatment (multidisciplinary vulvodynia program [MVP]) integrating psychological skills training, pelvic floor physiotherapy, and medical management on the primary outcomes of dyspareunia and sexual functioning, including distress. METHOD A total of 132 women with a diagnosis of PVD provided baseline data and agreed to participate in the MVP. Of this group, n = 116 (mean age 28.4 years, standard deviation 7.1) provided complete data at the post-MVP assessment, and 84 women had complete data through to the 3- to 4-month follow-up period. RESULTS There were high levels of avoidance of intimacy (38.1%) and activities that elicited sexual arousal (40.7%), with many women (50.4%) choosing to focus on their partner's sexual arousal and satisfaction at baseline. With treatment, over half the sample (53.8%) reported significant improvements in dyspareunia. Following the MVP, there were strong significant effects for the reduction in dyspareunia (P = 0.001) and sex-related distress (P < 0.001), and improvements in sexual arousal (P < 0.001) and overall sexual functioning (P = 0.001). More modest but still statistically significant were improvements in sexual desire, lubrication, orgasmic function, and sexual satisfaction. All improvements were retained at 2- to 3-month follow-up. CONCLUSION This study provides strong support for the efficacy of a multidisciplinary approach (psychological, pelvic floor physiotherapy, and medical management) for improving dyspareunia and all domains of sexual functioning among women with PVD. The study also highlights the benefits of incorporating sexual health education into general pain management strategies for this population.
Development and Migration of Protective CD8+ T Cells into the Nervous System following Ocular Herpes Simplex Virus-1 Infection1

After infection of epithelial surfaces, HSV-1 elicits a multifaceted antiviral response that controls the virus and limits it to latency in sensory ganglia. That response encompasses the CD8+ T cells, whose precise role(s) is still being defined; immune surveillance in the ganglia and control of viral spread to the brain were proposed as the key roles. We tracked the kinetics of the CD8+ T cell response across lymphoid and extralymphoid tissues after ocular infection. HSV-1-specific CD8+ T cells first appeared in the draining (submandibular) lymph node on day 5 and were detectable in both nondraining lymphoid and extralymphoid tissues starting on day 6. However, although lymphoid organs contained both resting (CD43lowCFSEhigh) and virus-specific cells at different stages of proliferation and activation, extralymphoid sites (eye, trigeminal ganglion, and brain) contained only activated cells that underwent more than eight proliferations (CD43highCFSEneg) and promptly secreted IFN-γ upon contact with viral Ags. Regardless of the state of activation, these cells appeared too late to prevent HSV-1 spread, which was seen in the eye (from day 1), trigeminal ganglia (from day 2), and brain (from day 3) well before the onset of a detectable CD8+ T cell response. However, CD8+ T cells were critical in reducing viral replication starting on day 6 and for its abrogation between days 8 and 10; CD8-deficient animals failed to control the virus, exhibited persisting high viral titers in the brain after day 6, and died of viral encephalitis between days 7 and 12. Thus, CD8+ T cells do not control HSV-1 spread from primary to tertiary tissues, but, rather, attack the virus in infected organs and control its replication in situ.
Aqua[N′-(3-ethoxy-2-oxidobenzyl-κO)furan-1-carbohydrazidato-κ2 N′,O]dioxidomolybdenum(VI)–4,4′-bipyridine (2/1)

The MoVI atom in the title co-crystal, [Mo(C14H12N2O4)O2(H2O)]·0.5C10H8N2, is O,N,O′-chelated by the deprotonated Schiff base and coordinated by the oxide and water O atoms in an octahedral geometry. The five-membered chelate ring is planar (r.m.s. deviation = 0.019 Å), but the six-membered chelate ring is puckered (r.m.s. deviation = 0.108 Å). Two mononuclear molecules are linked across a center of inversion by an O—Hwater⋯O hydrogen bond; adjacent dinuclear units are linked by an water–4,4′-bipyridine O—H⋯N hydrogen bond, generating a linear chain structure. The 4,4′-bipyridine molecule is disordered over two positions in a 1:1 ratio.
Clinico-radiological dissociation in multiple sclerosis: Future prospects

Magnetic resonance imaging (MRI) has significantly contributed to our capabilities of diagnosis multiple sclerosis (MS) since it is able to detect demyelinating lesions in almost 100% of patients. However, there are modest correlations between irreversible disability and white matter lesion load, as measured by T2-weighted MRI scans, which represents the clinicoradiological paradox of MS. We report the case of a patient with MS and few neurological manifestations despite extensive T2 visible morphologic abnormalities. The use of non-conventional MRI techniques, which are more specific in the analysis of the pathological substrate of demyelinating lesions and normal appearing brain matter (both white and gray matter), might assist us to overcome this limitation of conventional MRI.
Effect of anabolic steroids on skeletal muscle mass during hindlimb suspension.

The efficacy of anabolic steroid treatment [0.3 or 0.9 mg nandrolone decanoate (Deca-Durabolin) per day] was examined in the context of sparing rodent fast-twitch plantaris and slow-twitch soleus muscle weight, sparing subcellular protein, and altering isomyosin expression in response to hindlimb suspension. Female rats were assigned to four groups (7 rats/group for 6 wk): 1) normal control (NC), 2) normal steroid (NS), 3) normal suspension (N-SUS), and 4) suspension steroid (SUS-S). Compared with control values for the plantaris and soleus muscles, suspension induced 1) smaller body and muscle weight (P less than 0.05), 2) losses in myofibril content (mg/muscle, P less than 0.05), and 3) shifts in the relative expression (expressed as %of total isomyosin) of isomyosins which favored lesser slow myosin and greater fast myosin isotypes (P less than 0.05). Steroid treatment of suspended animals (SUS-S vs. N-SUS) partially spared body and muscle weight (P less than 0.05) and spared plantaris but not soleus myofibril content (mg/muscle, P less than 0.05). However, steroid treatment did not modify the isomyosin pattern induced by suspension. In normal rats (NS vs. NC), steroid treatment enhanced body and plantaris muscle weight but not soleus weight (P less than 0.05) and did not alter isomyosin expression in either muscle type. Collectively these data suggest that in young female rats anabolic steroids 1) enhance the body weight and the weight of a fast-twitch ankle extensor in normal rats, 2) ameliorate the loss in body weight, fast-twitch muscle weight and protein content and slow-twitch muscle weight associated with hindlimb suspension.

Materials in Participatory Design Processes

This dissertation presents three years of academic inquiry into the question of what role materials play in interaction design and participatory design processes. The dissertation aims at developing conceptual tools, based on Deweys pragmatism, for understanding how materials aid design reflection. It has been developed using a research-through-design approach in which the author has conducted practical design work in order to investigate and experiment with using materials to scaffold design inquiry. The results of the PhD work is submitted as seven separate papers, submitted to esteemed journals and conferences within the field of interaction design and HCI. The work is motivated both by the growing interest in materials in interaction design and HCI and the interest in design processes and collaboration within those fields. At the core of the dissertation lies an interest in the many different materials used during the design process: sketches, prototypes as well as the materials we shape products out of: physical and digital materials now form a unity of computation and physical materials that has given rise to a new research interest in design and materiality. The main results from the dissertation are an understanding of design materials that draws on pragmatist philosophy. The papers and overview article highlights how materials in a pragmatist perspective are more than the matter out of which we shape an idea. Rather they structure the entire process of inquiry, helping us frame problems, inspire solutions and try out these solutions in practice. This framework, developed in several of the submitted papers, is tested and illustrated through a series of experimental design cases.
Frequency and Costs of Diagnostic Imaging in Office Practice‐A Comparison of Self‐Referring and Radiologist‐Referring Physicians

BACKGROUND To assess possible differences in physicians' practices with respect to diagnostic imaging, we compared the frequency and costs of imaging examinations as performed by primary physicians who used imaging equipment in their offices (self-referring) and as ordered by physicians who always referred patients to radiologists (radiologist-referring). METHODS Using a large, private insurance-claims data base, we analyzed 65,517 episodes of outpatient care by 6419 physicians for acute upper respiratory symptoms, pregnancy, low back pain, or (in men) difficulty urinating. The respective imaging procedures studied were chest radiography, obstetrical ultrasonography, radiography of the lumbar spine, and excretory urography, cystography, or ultrasonography. RESULTS For all four clinical presentations, the self-referring physicians obtained imaging examinations 4.0 to 4.5 times more often than the radiologist-referring physicians (P less than 0.0001 for all four). For chest radiography, obstetrical ultrasonography, and lumbar spine radiography, the self-referring physicians charged significantly more than the radiologists for imaging examinations of similar complexity (P less than 0.0001 for all three). The combination of more frequent imaging and higher charges resulted in mean imaging charges per episode of care that were 4.4 to 7.5 times higher for the self-referring physicians (P less than 0.0001). These results were confirmed in a separate analysis that controlled for the specialty of the physician. CONCLUSIONS Physicians who do not refer their patients to radiologists for medical imaging use imaging examinations more frequently than do physicians who refer their patients to radiologists, and the charges are usually higher when the imaging is done by the self-referring physician. From our results it is not possible to determine which group of physicians uses imaging more appropriately.
