Graph-Based Shape Analysis Beyond Context-Freeness
We develop a shape analysis for reasoning about relational properties of data
structures. Both the concrete and the abstract domain are represented by
hypergraphs. The analysis is parameterized by user-supplied indexed graph
grammars to guide concretization and abstraction. This novel extension of
context-free graph grammars is powerful enough to model complex data structures
such as balanced binary trees with parent pointers, while preserving most
desirable properties of context-free graph grammars. One strength of our
analysis is that no artifacts apart from grammars are required from the user;
it thus offers a high degree of automation. We implemented our analysis and
successfully applied it to various programs manipulating AVL trees,
(doubly-linked) lists, and combinations of both
Applying Anti Oppressive, Empowerment, and Strengths Based Approaches to Social Work Practice with Hmong Clients
This conceptual article discusses social work practice with Hmong Americans using a framework that embraces anti-oppressive practice, empowerment and strengths-based approaches. Specifically, the Hmong kinship social construct of kwv tij neej tsa (pronounced: ku tee ning ja) is used to elaborate on the importance of upholding family relationships that transcends the worker-client relationship. Social workers are encouraged to empower Hmong to seek and ask for resources that support their collective value of connection to family and group identity, which is a strength that contributes to resilience and buffers against historically oppressive practices and systems
HMong Parent Day/Hnub Txhawb Nqa Niam Txiv: Implementing Psychosociocultural Educational Programming to Honor Rau Siab
This paper describes the interrelated conceptual activities that took a Psychosociocultural (PSC) approach to direct best practices, interactions, and processes to implement HMong Parent Days effectively. The purpose of HMong Parent Day/ Hnub Txhawb Nqa Niam Txiv, a culturally-centered community-focused intervention, was to bring HMong parents onto a midwestern predominantly White university campus for a day of college knowledge. The day honored HMong parents\u27 support of their children into and through higher education via the cultural value of rau siab (hard work). Three levels of learning that emergent as new knowledge for HMong parents were highlighted and discussed relative to the PSC approach. Implications for scholars and university personnel were provided. The benefits of a culturally-centered community-focused intervention were discussed

An oesophageal pulse oximetry system utilising a fibre-optic probe
A dual-wavelength fibre-optic pulse oximetry system is described for the purposes of estimating oxygen saturation (SpO2) from the oesophagus. A probe containing miniature right-angled glass prisms was used to record photoplethysmographic (PPG) signals from the oesophageal wall. Signals were recorded successfully in 19 of 20 patients, demonstrating that PPG signals could be reliably obtained from an internal vascularised tissue site such as the oesophageal epithelium. The value of the mean oxygen saturation recorded from the oesophagus was 94.0 ± 4.0%. These results demonstrate that SpO2 may be estimated in the oesophagus using a fibre-optic probe
Incidence and recurrence of acute otitis media in Taiwan's pediatric population
OBJECTIVE: To report the incidence and recurrence of acute otitis media (AOM) in Taiwan's pediatric population. METHODS: Information from children (aged <= 12 years) with a diagnosis of AOM was retrieved from the 2006 National Healthcare Insurance claims database. We calculated the cumulative incidence rate and the incidence density rate of recurrent AOM within one year after the initial diagnosis in 2006. We used a multivariate logistic regression model to assess the predictors for recurrence of AOM. RESULTS: The annual incidence rate of AOM was estimated to be 64.5 cases per 1,000 children. The overall one-year cumulative incidence rate of recurrence was 33.1%, and the incidence density rate was 33.5 cases per 100 personyears, with the highest figure (41.2 cases per 100 person-years) noted for children aged 0-2 years. Recurrence was significantly associated with age, gender, place of treatment, and physician specialty. CONCLUSION: AOM remains a major threat to children's health in Taiwan. Male children and very young children require more aggressive preventive strategies to reduce the risk of recurrence
Surface Structures Determined by Kinetic Processes: Adsorption and Diffusion of Oxygen on Pd(100)
Atomic oxygen forms a metastable c(2Ă—2) phase on Pd(100) under conditions of rapid adsorption (high pressure) and slow diffusion (low sample temperature). One possible explanation is that oxygen molecules require an 8-fold ensemble of empty sites for dissociative chemisorption, and that subsequent adatom motion is limited and creates no neighboring pairs of filled sites. We describe the properties of the adlayer predicted by such a model
F18 fluorodeoxyglucose uptake in progressive transformation of germinal centres
FDG-PET/CT is a widely established imaging modality for staging, restaging and monitoring therapy response in lymphoma patients. Progressive transformation of germinal centres (PTGC) is a benign condition presenting characteristically as asymptomatic lymphadenopathy. This paper presents a case of a 53-year-old man with a history of Hodgkin’s disease (HD) whose F18 FDG-PET/CT scan showed high uptake in left axillary lymph nodes (SUV 3.8). A subsequent, left axillary lymph node biopsy revealed PTGC. PTGC can present as a false positive finding on FDG-PET/CT in lymphoma patients and biopsy should be done in HD patients in clinical remission but have a positive FDG-PET/CT scan
Fermionic T-duality in the pp-wave limit
AdS5 X S5 and its pp-wave limit are self-dual under transformations involving
eight fermionic T-dualities, a property which accounts for symmetries seen in
scattering amplitudes in N=4 super-Yang-Mills. Despite strong evidence for
similar symmetries in the amplitudes of three-dimensional N=6 ABJM theory, a
corresponding self-duality in the dual geometry AdS4 X CP3 currently eludes us.
Here, working with the type IIA pp-wave limit of AdS4 X CP3 preserving twenty
four supercharges, we show that the pp-wave is self-dual with respect to eight
commuting fermionic T-dualities and not the six expected. In addition, we show
the same symmetry can be found in a superposition pp-wave and a generic pp-wave
with twenty and sixteen unbroken supersymmetries respectively, strongly
suggesting that self-duality under fermionic T-duality may be a symmetry of all
pp-waves.Comment: 21 pages, typos fixe
