Automorphism groups and adversarial vertex deletions

Any finite group can be encoded as the automorphism group of an unlabeled simple graph. Recently Hartke, Kolb, Nishikawa, and Stolee (2010) demonstrated a construction that allows any ordered pair of finite groups to be represented as the automorphism group of a graph and a vertex-deleted subgraph. In this note, we describe a generalized scenario as a game between a player and an adversary: An adversary provides a list of finite groups and a number of rounds. The player constructs a graph with automorphism group isomorphic to the first group. In the following rounds, the adversary selects a group and the player deletes a vertex such that the automorphism group of the corresponding vertex-deleted subgraph is isomorphic to the selected group. We provide a construction that allows the player to appropriately respond to any sequence of challenges from the adversary. Automorphisms of graphs are incredibly unstable. The slightest perturbation of the graph can greatly change the automorphism group. In this note, we show there exist graphs whose automorphism groups can change dramatically under certain sequences of vertex deletions. We consider undirected, unlabeled, and simple graphs, denoted F, G, or H, and finite groups, denoted G. The automorphism group of a graph G is denoted Aut(G). Frucht [3] proved that graphs have the ability to encode the structure of any finite group.
A phase-based single-bit Delta-Sigma ADC architecture

A Phase-based Delta-Sigma (ΔΣ) Analog-to-Digital Converter (ADC) adopting a Delay-Locked-Loop (DLL) mechanism is presented. It is realized by a modification of a DLL using a Voltage-Controlled Delay Line (VCDL) based quantizer and a charge pump in the feedback path. The proposed architecture offers both reference jitter shaping and quantization noise shaping. Simulation results show that the proposed ΔΣ ADC achieved 7.99 bits resolution with OSR =32 for a 10 MHz signal bandwidth.
Intervention Ecology: Applying Ecological Science in the Twenty-first Century

Rapid, extensive, and ongoing environmental change increasingly demands that humans intervene in ecosystems to maintain or restore ecosystem services and biodiversity. At the same time, the basic principles and tenets of restoration ecology and conservation biology are being debated and reshaped. Escalating global change is resulting in widespread no-analogue environments and novel ecosystems that render traditional goals unachievable. Policymakers and the general public, however, have embraced restoration without an understanding of its limitations, which has led to perverse policy outcomes. Therefore, a new ecology, free of pre- and misconceptions and directed toward meaningful interventions, is needed. Interventions include altering the biotic and abiotic structures and processes within ecosystems and changing social and policy settings. Interventions can be aimed at leverage points, both within ecosystems and in the broader social system—particularly, feedback loops that either maintain a particular state or precipitate a rapid change from one state to another.
Penser la diversité des pratiques médiatiques

Les transformations sociotechniques qui travaillent les pratiques d’usage, de reception et de participation mediatiques remettent en question les categories fondamentales de la recherche sur les audiences et les publics – « l’audience » et « le public », bien evidemment, mais aussi « la communaute ». Dans un premier temps, l’article presente et discute quelques grandes strategies conceptuelles autour de l’audience et du public visant a donner sens a la transformation des pratiques mediatiques. Ces strategies sont la substitution, l’hybridation, la variation, l’articulation et la desolidarisation des criteres de definition. Dans un second temps, l’article evalue le potentiel heuristique et analytique de la categorie du reseau lorsqu’il s’agit de questionner et d’etudier la diversite et l’articulation des pratiques mediatiques. Sont mis en avant six criteres de definition du reseau qui permettent de specifier certains modes d’action avec/par les medias, mieux que ne le font les notions d’audience, de public et de communaute : (1) la construction des relations, (2) la co-creation de contenus ou de technologies, (3) le partage, la circulation, (4) la dedifferenciation des espaces, (5) l’individualisation du temps et (6) le court-circuitage des intermediaires. En guise de conclusion, l’article evoque quelques problemes que pose la notion de reseau et suggere des pistes d’approfondissement.
Cytomegalovirus Infection in Children Undergoing Open-Heart Surgery 1

A group of 124 children undergoing open-heart surgery was followed prospectively in order to estimate the risk of cytomegalovirus (CMV) infection due to transfused blood. Ninety-three patients (75%) had complement fixation (CF) titers of < 1:4 against CMV on admission. Of this seronegative subgroup, nine patients (9.7%) subsequently became infected with CMV. All nine showed seroconversion, and six were viruric 12-14 weeks after surgery. Comparative seroepidemiological studies of the hospital population showed that in the age ranges studied (3-16 yr), the infections seen in the study group represented a significant excess over expectation. This infection rate was consistent with a model of transmission by blood transfusion with a risk of 2.7% per unit but not proven. Thirty-one patients had CF antibody to CMV on admission. CMV was isolated from 14% of urines of seropositive children both before and after surgery, but only two patients showed CF antibody rises to CMV. Thus the frequency of CMV infection associated with open-heart surgery and transfusion could not be calculated in the seropositive subgroup. CMV infection was not related to the primary diagnosis or to Down's syndrome.
Inclusive Physical Education from the Perspective of Students with Physical Disabilities

The study describes the phenomenon of inclusive physical education from the perspective of students with disabilities. The experience of 9 elementary school-aged students with physical disabilities (6 males and 3 females with a mean age of 11 years, 1 month) was captured by way of focus group interviews, field notes, and participant drawings. The thematic analysis uncovered a persistent dichotomy in how the participants experienced physical education. Good days were revealed in the themes of sense of belonging, skillful participation, and sharing in the benefits. Bad days were overshadowed by negative feelings revealed in the themes of social isolation, questioned competence, and restricted participation. The students’ experiences were discussed within the conceptual framework of ecological perception and affordance theory (Gibson, 1977, 1979).
The errors in FFT estimation of the Fourier transform

The problem of determining the error in approximating the Fourier transform by the discrete Fourier transform is studied. Exact formulas for the relative error are established for classes of functions, called canonical-k (k/spl ges/0), and asymptotic error formulas are established for a much wider class of functions, called order-k. The formulas are dependent only on the class and not on the function in the class whose Fourier transform is being approximated, and this facilitates the application of the results.
Predictors of Iranian women's intention to first papanicolaou test practice: An application of protection motivation theory.

BACKGROUND AND AIM Given the importance of papanicolaou (Pap) test in the early detection and timely treatment of cervical cancer, present study was designed to determine predictors of a sample of Iranian women's intention to first Pap test practice based on the protection motivation theory (PMT) variables. MATERIALS AND METHODS In this cross-sectional study, a total of 240 women referral to the 30 primary health care clinics were selected. They completed a developed scale based on PMT variables including intention, perceived vulnerability and severity, fear, response costs, response efficacy and self-efficacy. Path analysis was used to determine the association between predictive factors and intention. RESULTS The results showed that PMT had goodness of fit with a χ2/df = 2.37, df = 28, P= 0.001 and RMSEA = 0.076. PMT explained 42% of the variance in women's intention to get first Pap smear test. Self-efficacy (b = 0.55, P< 0.001) and response efficacy (b = 0.19, P< 0.001) were found to be the predictors of intention. CONCLUSION These findings may be used to develop tailored, theory-based educational interventions associated with Pap testing among women.
Nondirective meditation activates default mode network and areas associated with memory retrieval and emotional processing

Nondirective meditation techniques are practiced with a relaxed focus of attention that permits spontaneously occurring thoughts, images, sensations, memories, and emotions to emerge and pass freely, without any expectation that mind wandering should abate. These techniques are thought to facilitate mental processing of emotional experiences, thereby contributing to wellness and stress management. The present study assessed brain activity by functional magnetic resonance imaging (fMRI) in 14 experienced practitioners of Acem meditation in two experimental conditions. In the first, nondirective meditation was compared to rest. Significantly increased activity was detected in areas associated with attention, mind wandering, retrieval of episodic memories, and emotional processing. In the second condition, participants carried out concentrative practicing of the same meditation technique, actively trying to avoid mind wandering. The contrast nondirective meditation > concentrative practicing was characterized by higher activity in the right medial temporal lobe (parahippocampal gyrus and amygdala). In conclusion, the present results support the notion that nondirective meditation, which permits mind wandering, involves more extensive activation of brain areas associated with episodic memories and emotional processing, than during concentrative practicing or regular rest.
Understanding Social Connectedness in College Women and Men

A sense of connectedness for men was hypothesized to be based on relationships that emphasize forms of social comparison, whereas a sense of connectedness for women was hypothesized to be based on relationships that emphasize forms of intimacy and physical proximity. The results from this study generally supported the hypotheses for both women and men. For women, relationships that emphasized reliable alliance and not guidance contributed to social connectedness. For men, relationships that emphasized reassurance of worth but not reliable alliance or opportunity for nurturance contributed to social connectedness. Differences in how women and men construct social connectedness are discussed in terms of counseling implications and future research.
CYP2E1 Polymorphism, Cigarette Smoking, p53 Expression, and Survival in Non-small Cell Lung Cancer: A Long Term Follow-up Study

The expression of selected gene products involved in cell differentiation and cell growth and genetic polymorphism of detoxifying genes was examined in 105 surgically resected nonsmall cell lung cancer (NSCLC) patients, and the relationship of these factors was correlated with cigarette smoking and patient survival. Genotyping of peripheral blood lymphocytes from 87 patients was performed for CYP2E1, GSTM1, GSTT1, mEH, and MPO detoxifying genes using polymerase chain reaction. Formalin-fixed, paraffin-embedded tissue was immunostained with antibodies to p53, p27, phospho-AKT, and bcl-2 using the avidin–biotin–peroxidase method and tissue microarray technique. Tumors were assigned a positive or negative score based on more than 10% of tumor cells staining positive with the antibody. The subtypes of NSCLC included 48 adenocarcinomas, 47 squamous cell carcinomas, and 10 large cell undifferentiated carcinomas. A total of 54 tumors were pathologic stage I, 23 were stage II, and 26 were stage III. All subjects smoked (range, 10–175 pack-years; mean, 60 pack-years). The mean overall survival was 112 weeks (median, 129 weeks). Patients with p53-positive tumors had significantly fewer pack-years of smoking (52 pack-years vs 72 pack-years; P = 0.021), smoked fewer years (34 years vs 40 years; P = 0.018), and had significantly better survival compared with those with p53-negative tumors (P = 0.045). When smoking history was further analyzed, the authors found that p53 expression was associated with the number of years smoked and not the number of packs smoked per day. Patients with squamous cell carcinoma had smoked longer compared with those with adenocarcinoma (P = 0.011). Significant association was seen between the CYP2E1 wild-type allele and better survival (P = 0.016). Patients with stage I tumors had better survival compared with stages II and III (P = 0.032). No association was found between survival and tumor type; tumor differentiation; expression of phospho-AKT, p27, and bcl-2; and polymorphic metabolizing genes other than CYP2E1. The significant association of long duration of smoking (>40 years) with loss of p53 expression and poor survival suggests inactivation of the protective p53 pathway in those who had a history of more than 40 years of smoking.
Magnitude estimation for early warning applications using the initial part of P waves: A case study on the 2008 Wenchuan sequence

A period parameter τc and an amplitude parameter Pd determined from the very beginning of P wave are important for earthquake early warning (EEW), yet their dependence on source mechanism, focal depth and epicentral distance has not been fully studied. After the devastating Mw7.9 Wenchuan earthquake, hundreds of M4‐6 earthquakes occurred with diverse focal mechanisms and depth range of 2–20 km. We calculate τc and Pd of these aftershocks and examine their dependence on magnitude, τc, distance, and depth. We find that τc correlates well with magnitude, but joint regression including distance and depth does not significantly improve the correlation. The effect of focal mechanism on the τc ‐magnitude correlation is not obvious. When P wave is nodal, τc measurement becomes inaccurate. Also, τc is systematically greater for slow earthquakes, leading to a possible false alarm. Thus, more studies are required to discriminate slow earthquakes for robust early warning.
Sleep quality among dental students and its association with academic performance

Objective: To investigate the sleep patterns of dental students from different academic levels and to determine the effect of sleep patterns on the academic performance of students. Methods: A self-reported questionnaire was designed and distributed among 1160 students from clinical and non-clinical levels to measure the sleep-related variables and academic performance. The questionnaire included questions on demographics, sleep habits, sleep quality index (PSQI), and grade point averages (GPAs). Data were analyzed with standard statistical software (SPSS, Statistical Package for the Social Sciences, version 22, Chicago, IL, USA). Results: The response rate was 62%. Sixty five percent of the students described their sleep as good or very good, whereas 35% described their sleep as bad or very bad. The mean number of hours of sleep per night for all students was 5.85 ± 1.853 hours. The GPA had a significant negative correlation with PSQI scores. The clinical group showed a stronger negative correlation (P = −0.351) than the nonclinical group (P = −0.134). Conclusion: It can be concluded that dental students tend to have poor sleep quality, which is unknown to them. Poor sleep quality was associated with lower academic performance, especially in clinical years.
Community participation and inclusion: people with disabilities defining their place

Disability‐related public policy currently emphasises reducing the number of people experiencing exclusion from the spaces of the social and economic majority as being the pre‐eminent indicator of inclusion. Twenty‐eight adult, New Zealand vocational service users collaborated in a participatory action research project to develop shared understandings of community participation. Analysis of their narratives suggests that spatial indices of inclusion are quiet in potentially oppressive ways about the ways mainstream settings can be experienced by people with disabilities and quiet too about the alternative, less well sanctioned communities to which people with disabilities have always belonged. Participants identified five key attributes of place as important qualitative antecedents to a sense of community belonging. The potential of these attributes and other self‐authored approaches to inclusion are explored as ways that people with disabilities can support the policy objective of effecting a transformation from disabling to inclusive communities.
Laparoscopic Repair of Ventral Hernias: Nine Years’ Experience With 850 Consecutive Hernias

Objective To evaluate the efficacy and safety of laparoscopic repair of ventral hernias. Summary Background Data The recurrence rate after standard repair of ventral hernias may be as high as 12–52%, and the wide surgical dissection required often results in wound complications. Use of a laparoscopic approach may decrease rates of complications and recurrence after ventral hernia repair. Methods Data on all patients who underwent laparoscopic ventral hernia repair (LVHR) performed by 4 surgeons using a standardized procedure between November 1993 and October 2002 were collected prospectively (85% of patients) or retrospectively. Results LVHR was completed in 819 of the 850 patients (422 men; 428 women) in whom it was attempted. Thirty-four percent of completed LVHRs were for recurrent hernias. The patient mean body mass index was 32; the mean defect size was 118 cm2. Mesh, averaging 344 cm2, was used in all cases. Mean operating time was 120 min, mean estimated blood loss was 49 mL, and hospital stay averaged 2.3 days. There were 128 complications in 112 patients (13.2%). One patient died of a myocardial infarction. The most common complications were ileus (3%) and prolonged seroma (2.6%). During a mean follow-up time of 20.2 months (range, 1–94 months), the hernia recurrence rate was 4.7%. Recurrence was associated with large defects, obesity, previous open repairs, and perioperative complications. Conclusion In this large series, LVHR had a low rate of conversion to open surgery, a short hospital stay, a moderate complication rate, and a low risk of recurrence.
Trust transferability among similar contexts

Trust is a fundamental concern in electronic transactions and behavior of people are influenced by the situation. Motivated by that we present a state-of-the-art survey of context representation in trust management and provide main directions along which research efforts have been done. We propose a generalized model which considers different aspects of the relationship between context-awareness and trust management.
NBTI degradation: From transistor to SRAM arrays

A novel composite model had been recently introduced to physically explain the mean pMOS threshold voltage shift (VTP) induced by NBTI degradation at transistor level in a quantitative way. This model is here extended to include the statistical variations introduced by intrinsic fluctuations. In a second time, the model is extrapolated up to SRAM arrays by analyzing the SRAM bitcell sensitivity to transistor degradation. This approach allows quantitative prediction of NBTI-induced VMIN variations and access time Taa degradation during burn-in operations. The key findings include (a) demonstration of non-normality of VTP shift distribution (b) NBTI contribution to product VMIN drift arises from both mean VTP drift but also from increased VTP dispersion, and (c) VTP shift non-normality is smoothed out at product level by time-zero variation of the six transistors of the SRAM bitcell.
An Integral Perspective on Depression

The integral approach to therapy proposes to accommodate all the etiological factors of unipolar depression in its theory, as well as to make use of all existing therapies, both pharmacological and psychological, in the treatment of unipolar depression. Integral Therapy is compared to cognitive therapy to find evidence for its superiority over the cognitive approach. It appears that the cognitive therapy is more cost-effective than Integral Therapy as an individual approach in the treatment of depression, but that the integral perspective accounts better for etiological factors.
Early diagnosis of invasive pulmonary aspergillosis in hematologic patients: an opportunity to improve the outcome

Invasive pulmonary aspergillosis (IPA) is the leading invasive fungal disease in high-risk hematologic patients, including those with acute myeloid leukemia (AML) receiving chemotherapy for induction of remission, and allogeneic hematopoietic cell transplant (HCT) recipients. [1][1],[2][2] Studies
Diffusion-weighted MR of acute cerebral infarction: comparison of data processing methods.

BACKGROUND AND PURPOSE Some investigators have proposed that either calculated diffusion trace images or apparent diffusion coefficient (ADC) maps, which require imaging with multiple diffusion sensitivities and/or postacquisition image processing, are essential for the accurate interpretation of diffusion-weighted images in acute stroke because of the possible pitfalls of regional diffusion anisotropy, magnetic susceptibility artifacts, and confounding T2 effects, all of which alter signal on diffusion-weighted MR images. The purpose of our study was to compare the sensitivity, specificity, and accuracy of simple, orthogonal-axis diffusion-weighted imaging for the diagnosis of early cerebral infarction with three other sets of postacquisition-processed images: isotropic diffusion-weighted, diffusion trace-weighted, and diffusion trace images. METHODS Twenty-six consecutive adult patients with signs and symptoms consistent with a clinical diagnosis of early cortical and/or subcortical cerebral infarction and 17 control subjects were studied with multisection, single-shot, spin-echo echo-planar diffusion-weighted imaging at 1.5 T to generate a set of three orthogonal-axis diffusion-weighted images. Isotropic diffusion-weighted, diffusion trace-weighted, and diffusion trace (mean ADC) images were then generated off-line and all four sets of images were interpreted blindly by two neuroradiologists. RESULTS The average sensitivity, specificity, and accuracy for the orthogonal-axis diffusion-weighted images were 98.1%, 97.1%, and 97.7%, respectively. The average sensitivity, specificity, and accuracy for isotropic diffusion-weighted images were 88.5%, 100%, and 93% respectively. The average sensitivity, specificity, and accuracy for diffusion trace-weighted images were 82.7%, 73.6%, and 79.1%, respectively. The average sensitivity, specificity, and accuracy for diffusion trace images were 50.0%, 85.3%, and 64.0%, respectively. CONCLUSION Orthogonal-axis diffusion-weighted images have the highest sensitivity and accuracy and very high specificity for early cerebral infarction. Our data contradict the contention that quantitative diffusion maps, requiring imaging with multiple diffusion sensitivities and/or subsequent image processing, are necessary for clinical stroke imaging.
Activity Recognition and Future Prediction in Hospitals

In this paper, we firstly introduce our work [9] where we proposed for recognizing whole day activities using prior knowledge, and applied the method for real nursing sensor dataset we have collected. Then, we introduce the method for predicting the near future of nurses by integrating nurse activity data, location data, and medical records, based on our work [10]. For both works, we independently collected real and open nursing datasets with 2 weeks of accelerometers and training labels from 22 nurses for the former work, and nurse activity, location, medical payment, and nursing need data from 35 nurses and 96 patients for 40 days for the latter work.
