Dynamic Changes in Quantitative Features of Human Gastric Lesions

Quantitative DNA, morphometric cellular and nuclear variables were evaluated in surgical biopsies from patients with various gastric lesions: chronic gastritis, chronic ulcers, adenomatous polyps (gastric adenomas), primary carcinomas and their corresponding lymph‐node metastases. Paraffin‐embedded tissue sections were studied by static cytophotometry (plug method), karyometry (measurements with a graduated eyepiece micrometer of the major and minor axes of the elliptic nuclear profiles, and calculation of profile areas), and measurements of cellular profiles (largest and smallest caliper diameters). Tissue lymphocytes from the same slide were used as diploid controls for the DNA evaluations. An increase of both cellular and nuclear dimensions and DNA content was noted in all pathological tissues, as compared to normal mucosa; the highest values are found in primary gastric carcinomas. A progressive pattern increase of cellular and nuclear dimensions and of DNA content was observed through normal to cancerous tissues, chronic gastritis, chronic ulcers and adenomatous polyps (adenomas). Lymph‐node metastases, in our study, had smaller nuclear (cellular) dimensions than primary cancers.
Bregman Storage Functions for Microgrid Control

In this paper, we contribute a theoretical framework that sheds a new light on the problem of microgrid analysis and control. The starting point is an energy function comprising the “kinetic” energy associated with the elements that emulate the rotating machinery and terms taking into account the reactive power stored in the lines and dissipated on shunt elements. We then shape this energy function with the addition of an adjustable voltage-dependent term, and construct so-called Bregman storage functions satisfying suitable dissipation inequalities. Our choice of the voltage-dependent term depends on the voltage dynamics under investigation. Several microgrid controllers that have similarities or coincide with dynamics already considered in the literature are captured in our incremental energy analysis framework. The twist with respect to existing results is that our incremental storage functions allow for a large signal analysis of the coupled microgrid. This obviates the need for simplifying linearization techniques, and for the restrictive decoupling assumption in which the frequency dynamics is fully separated from the voltage one. A complete Lyapunov stability analysis of the various systems is carried out along with a discussion on their active and reactive power sharing properties.
Behavioral and psychiatric consequences of sleep-wake schedule disorders

Circadian rhythm sleep disorders (CRSDs) arise when an individual's sleep-wake rhythm mismatches the environmental 24-h schedule. Physiological data and genetic studies in patients with CRSDs suggest that these disorders result from abnormal functioning of the circadian timing system. Diagnosis involves recognition of the characteristics of CRSDs, which can be achieved by clinical interview and actigraphic monitoring of rest-activity patterns. Bright-light therapy and melatonin administration have proved to be the most effective treatment modalities of CRSDs. In psychiatric practice, CRSDs can be encountered on various occasions. Some evidence indicates that a deviant sleep-wake schedule might be a predisposing factor to personality disorders. CRSDs can emerge as an iatrogenic effect of certain psychoactive drugs, such as haloperidol and fluvoxamine. It is not uncommon that the daytime functional difficulties that accompany CRSDs are misinterpreted as symptoms of psychopathology. Recognition and awareness of these disorders should prevent years of erroneous diagnosis and treatment in these patients.
Continuous stress detection using a wrist device: in laboratory and real life

Continuous exposure to stress is harmful for mental and physical health, but to combat stress, one should first detect it. In this paper we propose a method for continuous detection of stressful events using data provided from a commercial wrist device. The method consists of three machine-learning components: a laboratory stress detector that detects short-term stress every 2 minutes; an activity recognizer that continuously recognizes user's activity and thus provides context information; and a context-based stress detector that exploits the output of the laboratory stress detector and the user's context in order to provide the final decision on 20 minutes interval. The method was evaluated in a laboratory and a real-life setting. The accuracy on 55 days of real-life data, for a 2-class problem, was 92%. The method is currently being integrated in a smartphone application for managing mental health and well-being.
The Nexus Between Disaggregated Public Spending and GDP in the Euro Area

This paper aims to analyze the nexus between disaggregated public spending and GDP in the Euro Area for the period 1990-2010 at a disaggregated level, using a time series approach. We estimated this nexus for ten items of public spending according to the COFOG functional classification. Taking into account cross-section dependence and group-wise heteroskedasticity, cointegration tests reveal a long-run relationship between real per capita GDP and real spending for defence, for housing and community amenities, and for recreation, culture and religion. Moreover, Granger causality tests results show clear evidence against the Keynesian view (G→Y). Finally, decomposing the GDP with Hodrick and Prescott filter, Estonia, Luxembourg, Ireland and Greece exhibit wider fluctuations. Some notes on the policy implications of this analysis conclude the paper.
Augmented Reality Effectiveness in Advertising

Large consumer suppliers, such as automotive manufacturers and retail companies, are beginning to implement augmented reality as part of their advertising strategy. Augmented reality (AR) is defined as the integration of digitally created media within an existing actual environment. This combination of virtual three-dimensional images within tangible surroundings provides unique sensory capabilities and communication opportunities. However, little research has been done on the true effectiveness of such ‘high-tech’ advertising methods. As a continuation of previous studies that examined the trends and directions of augmented reality technology and its potential application in visualization research and testing, a research study was implemented to examine effectiveness in augmented reality use in advertising. A qualitative assessment was completed that examined observers’ information retention and recall from augmented reality advertisements when compared to standard paper-based media. The results of this study are presented and discussed along with potential ramifications in various applications. Further research plans and recommendations are also discussed.
Role of Histone H3 Lysine 9 Methylation in Epigenetic Control of Heterochromatin Assembly

The assembly of higher order chromatin structures has been linked to the covalent modifications of histone tails. We provide in vivo evidence that lysine 9 of histone H3 (H3 Lys9) is preferentially methylated by the Clr4 protein at heterochromatin-associated regions in fission yeast. Both the conserved chromo- and SET domains of Clr4 are required for H3 Lys9methylation in vivo. Localization of Swi6, a homolog ofDrosophila HP1, to heterochomatic regions is dependent on H3 Lys9 methylation. Moreover, an H3-specific deacetylase Clr3 and a β-propeller domain protein Rik1 are required for H3 Lys9 methylation by Clr4 and Swi6 localization. These data define a conserved pathway wherein sequential histone modifications establish a “histone code” essential for the epigenetic inheritance of heterochromatin assembly.
Microstructural and Mechanical Characterization of Ceramic Substrates with Different Metallization for Power Applications

The properties of metalized ceramic substrates, e.g. used in power electronic devices, are mainly influenced by the metallization layer and the interface metal/ceramic. This study presents results from microstructural analyses and mechanical characterization of Direct Aluminum Bonded (DAB) substrates in comparison to Direct Copper Bonded (DCB) substrates. High resolution electron (SEM) and transmission electron microscopy (HRTEM) characterization in combination with crystallographic microanalysis using electron backscatter diffraction (EBSD) show the formation of cupric oxide areas in combination of a complex copper, manganese aluminate system at the aluminum oxide/copper (DCB) interface. For DAB substrates the formation of a ternary Al-Fe-Si phase system was revealed along the aluminum oxide/aluminum interface. The detected interface formation exposed on both substrates indicates strong adhesion bonding strength between alumina/ copper and aluminum, respectively. Based on temperature-dependent Berkovich nanoindentation testing at room temperature to 250 deg C, a decrease of indentation hardness and modulus was shown for both types of metallization. The thermal expansion behavior of both substrates was investigated by a digital image correction method (ARAMIS by GOM) based on grey scale correlation. CTE was found to vary significantly in dependence of the alumina thicknesses and the respective metallization.
Factors governing the consumption of explicit knowledge

Knowledge management as a field continues to receive resounding interest from scholars. While we have made progress in many areas of knowledge management, we are yet to understand what factors contribute to employee usage of knowledge artifacts. A field study of 175 employees in a software engineering organization was conducted to understand factors that govern consumption of explicit knowledge. We assert that the decision to consume knowledge can be framed as a problem of risk evaluation. Specifically, there are two sources of risk a consumer must evaluate prior to knowledge consumption—risk from the knowledge producer and risk from the knowledge product. We find support for the factors of perceived complexity, perceived relative advantage , and perceived risk as they relate to intentions to consuming knowledge.
The Experiences of Indigenous Young People Transitioning from Out-of-Home Care in Victoria, Australia

This chapter reports on exploratory research in Victoria, Australia, involving focus groups and interviews with service providers and Indigenous care leavers to examine the impact of existing support services. Indigenous children and young people are highly overrepresented in the Australian out-of-home care system. To date, neither specific research focusing on this group’s experiences as they transition from care nor an assessment of the Indigenous-specific and non-Indigenous supports and services available to them have been undertaken. Findings suggest that Aboriginal Community Controlled Organizations (ACCOs) play a positive role in working with non-Indigenous agencies to assist Indigenous care leavers. Participants identified a few key strategies to improve outcomes, such as facilitating stronger relationships between Indigenous and non-Indigenous services and improving ACCO resourcing.
'Net Neutrality', Non-Discrimination and Digital Distribution of Content Through the Internet

The vast majority of US residential consumers face a monopoly or duopoly in broadband Internet access. Up to now, the Internet was characterized by a regime of “net neutrality” where there was no discrimination in the price of a transmitted information packet based on the identities of either the transmitter or the receiver or based on the application or type of content that it contained. The providers of DSL or cable modem access in the United States, taking advantage of a recent regulatory change that effectively abolished net neutrality and non-discrimination protections, and possessing significant market power, have recently discussed implementing a variety of discriminatory pricing schemes. This paper discusses and evaluates the implication of a number of these schemes on prices, profits of the network access providers and those of the complementary applications and content providers, as well as the impact on consumers. We also discuss an assortment of anti-competitive effects of such price discrimination, and evaluate the possibility of imposition of net neutrality by law.
Novel Techniques for the Analysis of Wireless Integrated Voice/Data Networks.

Abstract : In this report, we consider the evaluation of data-packet delay in wireless integrated voice"data networks. In networks that support circuit-switched voice, the voice occupancy process satisfies a product-form solution under reasonable modeling assumptions. Although this product-form solution provides an accurate characterization of equilibrium voice-traffic behavior, it does not directly provide a method to evaluate data-packet delay. However, examination of each link separately in a manner that incorporates interaction with the rest of the network permits us to take advantage of the wireless nature of the network and obtain a three-flow characterization of each link, which also satisfies a product-form solution and is hence termed a "mini-product-form" solution. By matching the values of these flows to the average values obtained from the product-form solution of the entire network, we obtain a three-dimensional Markov chain characterization of the voice occupancy state on the link, which permits a simpler evaluation of data-packet delay. A further reduction is possible by converting the three-dimensional chain to a single-dimensional one. Performance results demonstrate that these models provide satisfactory delay estimates that also appear to be upper bounds on delay. (KAR) P. 2

The Prevalence of Chronic Obstructive Pulmonary Disease and the Determinants of Underdiagnosis in Women Exposed to Biomass Fuel in India- a Cross Section Study

Background and Objectives Tobacco smoking has been established as a major risk factor for chronic obstructive pulmonary disease (COPD) in women of developing countries, but emerging evidence suggests that biomass fuel is an important risk factor as well. The primary objective of the study was to find the true prevalence of COPD in Indian women exposed to biomass fuel using spirometry. We also aimed to find the determinants of underdiagnosis of COPD in these participants. Methods Women with a history of exposure to biomass fuel for >10 years were screened for COPD using spirometry following all standard protocols as per GOLD/ATS/ERS definitions. Results Of the 2868 women screened, a total of 529 (18.4%) women were confirmed to have COPD in which 123 (4.2%) were "Women with known COPD" and 406 (14.2%) "Women with new COPD". The mean age at the time of Diagnosis was 61±5.2 and 47±3.6 respectively. The duration of exposure to biomass fuel had a great impact on the risk of COPD with OR 1.2, 95% CI (1.1-1.9) for patients with 10-15 years exposure and OR 2.9, 95% CI (2.5-3.1) for exposure >25 years, p<0.001. Conclusion The prevalence of COPD among women exposed to biomass fuel is very high. A strong correlation was found between the risk of COPD and the duration of exposure along with the age at which the exposure to biomass fuel begins. Underdiagnosis of COPD was frequent in women due to the lack of the availability of spirometry, lack knowledge of hazards of biomass fuel, a low level of education and the ignorance of the health care provider being the important determinants of underdiagnosis.

Pearls & Oy-sters: Treatment of central sleep apnea with topiramate

A 67-year-old man with a history of epilepsy, cardiac failure, alcohol dependence, and hypercholesterolemia underwent a polysomnogram (PSG) study because of snoring and observed apnea during sleep. Body mass index was recorded at 25.9 kg/m2. Medications included metoprolol, valsartan, simvastatin, phenytoin, valproate, and levetiracetam. Prior echocardiogram had shown an ejection fraction of 35%. PSG showed an overall Central Apnea Index (CAI) of 18, with 18 central apneas/hour, 7 hypopneas/hour, 0 mixed apneas/hour, and 0 obstructive apneas/hour (figure 1). Central apneas displayed a crescendo-decrescendo pattern, consistent with CSB. Because of recurrent seizures, topiramate was added to the medication regimen, with a titration schedule to 100 mg twice per day. After 5 months, a second PSG for titration with adaptive servo-ventilation was obtained. Baseline portion of the study (about 90 minutes) showed a significant decrease in number of central apneas, with an overall CAI of 0, with 0 central apneas/hour, 12 hypopneas/hour, 0 mixed apneas/hour, 0 obstructive apneas per hour of sleep, and …
Revisiting common bug prediction findings using effort-aware models

Bug prediction models are often used to help allocate software quality assurance efforts (e.g. testing and code reviews). Mende and Koschke have recently proposed bug prediction models that are effort-aware. These models factor in the effort needed to review or test code when evaluating the effectiveness of prediction models, leading to more realistic performance evaluations. In this paper, we revisit two common findings in the bug prediction literature: 1) Process metrics (e.g., change history) outperform product metrics (e.g., LOC), 2) Package-level predictions outperform file-level predictions. Through a case study on three projects from the Eclipse Foundation, we find that the first finding holds when effort is considered, while the second finding does not hold. These findings validate the practical significance of prior findings in the bug prediction literature and encourage their adoption in practice.
Frequency of Behavior Witnessed and Conformity in an Everyday Social Context

Conformity is thought to be an important force in human evolution because it has the potential to stabilize cultural homogeneity within groups and cultural diversity between groups. However, the effects of such conformity on cultural and biological evolution will depend much on the particular way in which individuals are influenced by the frequency of alternative behavioral options they witness. In a previous study we found that in a natural situation people displayed a tendency to be ‘linear-conformist’. When visitors to a Zoo exhibit were invited to write or draw answers to questions on cards to win a small prize and we manipulated the proportion of text versus drawings on display, we found a strong and significant effect of the proportion of text displayed on the proportion of text in the answers, a conformist effect that was largely linear with a small non-linear component. However, although this overall effect is important to understand cultural evolution, it might mask a greater diversity of behavioral responses shaped by variables such as age, sex, social environment and attention of the participants. Accordingly we performed a further study explicitly to analyze the effects of these variables, together with the quality of the information participants' responses made available to further visitors. Results again showed a largely linear conformity effect that varied little with the variables analyzed.
