Published: October 2011

ABSTRACTAuthentication, authorization, and accounting services provide the framework on top of which a reliable, secure, and robust accounting system can be built. In a previous work of ours, we have presented a flexible and, most importantly, generic accounting scheme for next generation networks. In this paper, we substantially improve our previous work by providing the required Diameter application namely SIP‐Accounting (SIPA) that enables the use of our accounting scheme for Session Initiation Protocol (SIP) services. Additionally, in an effort to protect the service providers and the end users against accounting frauds, we implement an add‐on mechanism referred to as SIPA+ to combat attacks targeting the core accounting functions and the integrity of the respective accounting messages. Using the implemented SIPA and SIPA+ prototypes, we conducted a complete set of experiments testing several configurations and two distinct scenarios. The results reveal that the proposed accounting system and its security add‐on are fully operable in SIP environments without incurring much cost in terms of performance and overhead.

AbstractCancer is arguably the ultimate complex biological system. Solid tumors are microstructured soft matter that evolves as a consequence of spatio‐temporal events at the intracellular (e.g., signaling pathways, macromolecular trafficking), intercellular (e.g., cell–cell adhesion/communication), and tissue (e.g., cell–extracellular matrix interactions, mechanical forces) scales. To gain insight, tumor and developmental biologists have gathered a wealth of molecular, cellular, and genetic data, including immunohistochemical measurements of cell type‐specific division and death rates, lineage tracing, and gain‐of‐function/loss‐of‐function mutational analyses. These data are empirically extrapolated to a diagnosis/prognosis of tissue‐scale behavior, e.g., for clinical decision. Integrative physical oncology (IPO) is the science that develops physically consistent mathematical approaches to address the significant challenge of bridging the nano (nm)–micro (µm) to macro (mm, cm) scales with respect to tumor development and progression. In the current literature, such approaches are referred to as multiscale modeling. In the present article, we attempt to assess recent modeling approaches on each separate scale and critically evaluate the current ‘hybrid‐multiscale’ models used to investigate tumor growth in the context of brain and breast cancers. Finally, we provide our perspective on the further development and the impact of IPO. WIREs Syst Biol Med 2012, 4:1–14. doi: 10.1002/wsbm.158This article is categorized under:

AbstractBackgroundTumor recurrence after resection of hepatocellular carcinoma is a common phenomenon. Re‐resection and radiofrequency ablation (RFA) are good options for treating recurrent HCC. This study compared the efficacy of these two modalities in the treatment of intrahepatic HCC recurrence after hepatectomy.MethodsFrom January 2001 to December 2008, a total of 179 patients developed intrahepatic HCC recurrence after hepatectomy. To treat the recurrence, 29 patients underwent re‐resection and 45 patients had RFA. Patient characteristics, clinicopathologic data, and survival outcomes were reviewed.ResultsChild‐Pugh status, time to develop first recurrence (12.2 vs. 8.7 months), and recurrent tumor size (2.1 vs. 2.1 cm) were comparable for the two groups. Time to develop a second intrahepatic recurrence after re‐resection and RFA was 5.9 and 4.0 months respectively. The 1‐, 3‐, and 5‐year disease‐free survival rates were 41.4%, 24.2%, and 24.2% after re‐resection and 32.2%, 12.4%, and 9.3% after RFA (p = 0.14). The 1‐, 3‐, and 5‐year overall survival rates were 89.7%, 56.5%, and 35.2% after re‐resection and 83.7%, 43.1%, and 29.1% after RFA (p = 0.48). For the second recurrence, 33.3% of patients underwent a second round of RFA and 10.0% underwent a third resection.ConclusionsThe two treatment modalities attained similar survival benefits in the management of recurrent HCC after hepatectomy. The high repeatability of RFA and that it can be delivered percutaneously render it a preferred treatment option for selected patients.

AbstractThe aim of this study was to develop and validate a method for the analysis of fatty acid methyl ester (FAMEs) content in tung biodiesel and blends with soybean biodiesel. The limits of detection (LOD) and quantification (LOQ), linearity, robustness, accuracy and precision were evaluated by using gas chromatography with mass spectrometry detection and impact electron ionization. The analytical curves showed correlation coefficients values higher than 0.99. The LOD and LOQ were 0.78 and 2.5 mg L−1 for all FAMEs, respectively. The values of accuracy were between 86 and 117%, with relative standard deviation lower than 8%. The method was applied to tung biodiesel and tung and soybean biodiesel blends in the following proportions: 15:85, 20:80, 25:75 (%v/v). All of them showed good performance. Since the method was also applied to soybean biodiesel, the efficiency of the method for the analysis of both pure tung biodiesel and blends with different raw materials was confirmed and the robustness of the method was evidenced.
Role of natural day-length and temperature in determination of summer and winter diapause in Pieris melete (Lepidoptera: Pieridae)
Authors: Xiao H.J. , Wu S.H. , He H.M. , Chen C. , Xue F.S. 
Published: October 2011

AbstractUnder field conditions, the cabbage butterfly, Pieris melete, displays a pupal summer diapause in response to relatively low daily temperatures and gradually increasing day-length during spring and a pupal winter diapause in response to the progressively shorter day-length. To determine whether photoperiod is ‘more’ important than temperature in the determination of summer and winter diapause, or vice versa, the effects of naturally changing day-length and temperature on the initiation of summer and winter diapause were systematically investigated under field conditions for five successive years. Field results showed that the incidence of summer diapause significantly declined with the naturally increasing temperature in spring and summer generations. Path coefficient analysis showed that the effect of temperature was much greater than photoperiod in the determination of summer diapause. In autumn, the incidence of diapause was extremely low when larvae developed under gradually shortening day-length and high temperatures. The incidence of winter diapause increased to 60–90% or higher with gradually shortening day-length combined with temperatures between 20.0°C and 22.0°C. Decreasing day-length played a more important role in the determination of winter diapause induction than temperature. The eco-adaptive significance of changing day-length and temperature in the determination of summer and winter diapause was discussed.
Assessing abundance and distribution of an invasive thrips Frankliniella schultzei (Thysanoptera: Thripidae) in south Florida

Published: October 2011

AbstractWithin-plant and within-field distribution of larvae and adults of an invasive thrips species, Frankliniella schultzei (Trybom) on cucumber, Cucumis sativus L. was studied in 2008 and 2009 in Homestead, Florida. The majority of thrips were found inhabiting flowers of cucumber plants and little or none was found on the other parts of the plant. Thrips were aggregated in the field, as indicated by the two regression models, Taylor's power and Iwao's patchiness regression. Iwao's patchiness regression provided a better fit than Taylor's power law. The distribution was clumped during the initial stages of infestation at the edges of the field and became random thereafter. However, with increase in population density, thrips again formed aggregates in the field. Based on the average pest density per flower in a ∼0.25-ha field, minimum sample size (number of flowers) required at the recommended precision level (0.25) was 51. The number of samples required at two levels of predetermined pest density was also calculated, which would help growers in collecting optimum number of samples required to determine the correct threshold level of pest in fields. Results from seasonal abundance indicated that density of thrips peaked during the fifth week of sampling with an average of 25 and 34 adults per ten flowers during autumn 2008 and 2009, respectively. Results from these studies will help growers and extension personnel in understanding the abundance and distribution of F. schultzei in the field, which are important components required in developing a sound management program.
BLACK AND WHITE BODY MASS INDEX VALUES IN NINETEENTH CENTURY DEVELOPING PHILADELPHIA COUNTY
Authors: CARSON SCOTT ALAN , HODGES PAUL E. 
Published: October 2011

SummaryThis paper demonstrates that although modern BMIs in the US have increased, 19th century BMIs in Philadelphia were lower than elsewhere within Pennsylvania, indicating that urbanization and agricultural commercialization were associated with lower BMIs. After controlling for stature, blacks consistently had greater BMI values than mulattos and whites; therefore, there is no evidence of a 19th century mulatto BMI advantage in the industrializing North. Farmers' BMIs were consistently heavier than those of non-farmers.

BackgroundThe increased occurrence of obstetric complications (OCs) in patients with schizophrenia suggests that alterations in neurodevelopment may be of importance to the aetiology of the illness. Abnormal cortical folding may reflect subtle deviation from normal neurodevelopment during the foetal or neonatal period. In the present study, we hypothesized that OCs would be related to cortical folding abnormalities in schizophrenia patients corresponding to areas where patients with schizophrenia display altered cortical folding when compared with healthy controls.MethodIn total, 54 schizophrenia patients and 54 healthy control subjects underwent clinical examination and magnetic resonance image scanning on a 1.5 T scanner. Information on OCs was collected from original birth records. An automated algorithm was used to calculate a three-dimensional local gyrification index (lGI) at numerous points across the cortical mantle.ResultsIn both schizophrenia patients and healthy controls, an increasing number of OCs was significantly related to lowerlGI in the left pars triangularis (p<0.0005) in Broca's area. For five other anatomical cortical parcellations in the left hemisphere, a similar trend was demonstrated. No significant relationships between OCs andlGI were found in the right hemisphere and there were no significant case–control differences inlGI.ConclusionsThe reduced cortical folding in the left pars triangularis, associated with OCs in both patients and control subjects suggests that the cortical effect of OCs is caused by factors shared by schizophrenia patients and healthy controls rather than factors related to schizophrenia alone.
Suicidality, ethnicity and immigration in the USA

Published: October 2011

BackgroundSuicide is the 11th leading cause of death in the USA. Suicide rates vary across ethnic groups. Whether suicide behavior differs by ethnic groups in the USA in the same way as observed for suicide death is a matter of current discussion. The aim of this report was to compare the lifetime prevalence of suicide ideation and attempt among four main ethnic groups (Asians, Blacks, Hispanics, and Whites) in the USA.MethodSuicide ideation and attempts were assessed using the World Mental Health version of the Composite International Diagnostic Interview (WMH-CIDI). Discrete time survival analysis was used to examine risk for lifetime suicidality by ethnicity and immigration among 15 180 participants in the Collaborative Psychiatric Epidemiological Surveys (CPES), a group of cross-sectional surveys.ResultsSuicide ideation was most common among Non-Hispanic Whites (16.10%), least common among Asians (9.02%) and intermediate among Hispanics (11.35%) and Non-Hispanic Blacks (11.82%). Suicide attempts were equally common among Non-Hispanic Whites (4.69%), Hispanics (5.11%) and Non-Hispanic Blacks (4.15%) and less common among Asians (2.55%). These differences in the crude prevalence rates of suicide ideation decreased but persisted after control for psychiatric disorders, but disappeared for suicide attempt. Within ethnic groups, risk for suicidality was low among immigrants prior to migration compared to the US born, but equalized over time after migration.ConclusionsEthnic differences in suicidal behaviors are explained partly by differences in psychiatric disorders and low risk prior to arrival in the USA. These differences are likely to decrease as the US-born proportion of Hispanics and Asians increases.
Ah-prefacing in Kiswahili second pair parts
Authors: D'Hondt Sigurd 
Published: October 2011

AbstractThis article presents a conversation-analytic account of the various usages of the Kiswahili particleahas it is routinely employed in naturally occurring Kiswahili conversation. Adopting a strategy reminiscent of the one Heritage and others adopted for Englishoh, it is argued that the seemingly disparate uses of this “language-specific object” represent various context-specific particularizations of a single semantic core. The basic claim is thatahconstitutes a response cry that indexes to the other interlocutors the speaker's negative evaluative stance toward a particular issue. In this capacity, it frequently occupies the turn-initial position of a second pair part. Depending on the specifics of the sequential environment, the “object” of the indexed stance is traceable to either the particular item that is being talked about or the action performed in the preceding first. In the former case, the particle is used to demonstrate the speaker's affiliation with the previous speaker. In the latter case, it is used to demonstrate his disaffiliation with the previous speaker.

Painful to playful: Quotidian frames in the conversational discourse of older Japanese women
Authors: Matsumoto Yoshiko 
Published: October 2011

AbstractConversations about serious life changes in old age may be expected to sound painful, but data of conversational narratives by elderly Japanese women even on topics related to illnesses or the death of a husband show highly engaging, lively exchanges, frequently accompanied by humor and laughter among the participants. The common feature in the conversations recounting psychologically intense experiences is a shift to detailed depictions of specific scenes from the quotidian perspective. This phenomenon, which I call quotidian reframing, is signaled by linguistic and paralinguistic quotidian framing cues. Quotidian reframing can function as a useful discourse strategy to relieve tension and let the participants regain the feeling or stance of quotidian self, the identity that they consider “normal.” A detailed account of the quotidian frame draws on such ideas as frame, footing, lamination, and positioning.

AbstractIntroduction: Radiographic findings of dengue fever have not yet been clearly elucidated in relation to clinical and serological findings, despite the fact that two-fifths of the world population lives in areas where the virus is endemic. The current study is a retrospective analyzis of ultrasonographic (USG) features of patients presenting with probable dengue fever during the outbreak of DF of 2006 in North India.Methods: Case records of a 169 patients with probable dengue fiver were included. Ten individual sonographic parameters were reviewed vis-à-vis ascites, hepatomegaly, splenomegaly, gall bladder wall edema (GBWE), pleural effusion (right or left or both), pericardial effusion, pericholecystic collection, perinephric collection. Subjects who had GB wall thickness >3 mm as measured on ultrasound were identified as positive for GBWE. The cases were analyzed in view of their serological profile.Results: The mean age of the subjects was 27.9 +/− 13.4 years. The mean value of the platelet count was 57.4 +/− 22.3 x 103/cmm. The most common ultrasonographic feature was ascites (126, 74.6%) followed by gall bladder wall edema (122, 72%), hepatomegaly (78, 46.2%), splenomegaly (66, 39.1%) and pericholecystic collection (63, 37.3%); 48 (28.4%) subjects demonstrated evidence of pleural effusion on the right side, while 19 (11.2%) had bilateral effusion. None of the subjects had an isolated left pleural effusion. Twenty-seven (16%) subjects reported bleeding manifestations in the form of petechiae and five (3%) developed renal dysfunction. Presence of pleural and pericardial effusions was found to be specific while ascites and GBWE were identified as highly sensitive markers for seropositive Primary DF.Conclusions: Ultrasonographic evidence of ascites, pleuro-pericardial effusion, and gallbladder wall edema are rapidly aquired, non-invasive markers of dengue and can be helpful before serological investigations become available. These findings may indicate severity and may herald the onset of bleeding (petechiae) or predict the development of acute renal dysfunction.
Occulting the past. Conceptualizing forgetting in the history and archaeology of Sylvester Manor
Authors: Hayes Katherine 
Published: October 2011

AbstractIn this paper I argue that we should attend to why and how forgetting happens in concert with the construction of social memory, history, identity and heritage. Through a focus on processes of forgetting, this discussion offers a new set of interpretations of early colonial Sylvester Manor, a 17th-century plantation site in coastal New York. More specifically, the construction of racial categories over several centuries implicates social memory and forgetting, and introduces issues to the manner in which we remember the site where people of European, African and Native American ancestry met. This analysis views memory and forgetting not only as historical vectors in racialization, but also as factors in current identity politics.
Perceptions of Liao urban landscapes. Political practices and nomadic empires
Authors: Lin Hu 
Published: October 2011

AbstractIn traditional models, nomadic empires are often depicted as ‘parasitic’ on the neighbouring sedentary polities. Inspired by the development of anthropologies and archaeologies of colonialism, this paper adopts the political-landscape approach to address the emerging steppe urbanism of the nomadic Liao Empire. Perceptions of Liao urban landscapes are discussed from six viewpoints – settlement location, city walls, architectural orientation, camping sites, spatial segregation and sacred places – in order to understand the political practices of city making. I argue that the nomadic Khitan did not simply emulate spatial strategies of settled agricultural polities in the heartland of China, but rather produced a radically new form of urbanism that was brought forth as one of the creative instruments constitutive of authority, formed and transformed in the process of nomadic empire building in which traditions of nomadic pastoralism with ties to eastern Eurasia were manipulated and remade along with Chinese urban planning.
WEAKLY CLASSICAL THEORIES OF IDENTITY
Authors: SCHECHTER JOSHUA 
Published: October 2011

AbstractThere are well-known quasi-formal arguments that identity is a “strict” relation in at least the following three senses: (1) There is a single identity relation and a single distinctness relation; (2) There are no contingent cases of identity or distinctness; and (3) There are no vague or indeterminate cases of identity or distinctness. However, the situation is less clear cut than it at first may appear. There is a natural formal theory of identity that is very close to the standard classical theory but which does not validate the formal analogues of (1)–(3). The core idea is simple: We weaken the Principle of the Indiscernibility of Identicals from a conditional to an entailment and we adopt a weakly classical logic. This paper investigates this weakly classical theory of identity (and related theories) and discusses its philosophical ramifications. It argues that we can accept a reasonable theory of identity without committing ourselves to the uniqueness, necessity, or determinacy of identity.
LL37 and hBD-3 elevate the β-1,3-exoglucanase activity of Candida albicans Xog1p, resulting in reduced fungal adhesion to plastic

Published: October 2011

The opportunistic fungus Candida albicans causes oral thrush and vaginal candidiasis, as well as candidaemia in immunocompromised patients including those undergoing cancer chemotherapy, organ transplant and those with AIDS. We previously found that the AMPs (antimicrobial peptides) LL37 and hBD-3 (human β-defensin-3) inhibited C. albicans viability and its adhesion to plastic. For the present study, the mechanism by which LL37 and hBD-3 reduced C. albicans adhesion was investigated. After AMP treatment, C. albicans adhesion to plastic was reduced by up to ~60% and was dose-dependent. Our previous study indicated that LL37 might interact with the cell-wall β-1,3-exoglucanase Xog1p, which is involved in cell-wall β-glucan metabolism, and consequently the binding of LL37 or hBD-3 to Xog1p might cause the decrease in adhesion. For the present study, Xog1p(41–438)-6H, an N-terminally truncated, active, recombinant construct of Xog1p and Xog1p fragments were produced and used in pull-down assays and ELISA in vitro, which demonstrated that all constructs interacted with both AMPs. Enzymatic analyses showed that LL37 and hBD-3 enhanced the β-1,3-exoglucanase activity of Xog1p(41–438)-6H approximately 2-fold. Therefore elevated Xog1p activity might compromise cell-wall integrity and decrease C. albicans adhesion. To test this hypothesis, C. albicans was treated with 1.3 μM Xog1p(41–438)-6H and C. albicans adhesion to plastic decreased 47.7%. Taken together, the evidence suggests that Xog1p is one of the LL37/hBD-3 targets, and elevated β-1,3-exoglucanase activity reduces C. albicans adhesion to plastic.
