Comparison of Algorithms for the Closed-Loop Control of Blood Glucose Using the Artificial Beta Cell

Over the past 15 years, several algorithms have been proposed and used for closed-loop blood glucose regulation. Their intent is to artificially replace the normal responses of the pancreatic beta cell absent in insulin-dependent diabetes. All of these algorithms calculate insulin infusion rates on the basis of minute-by-minute measurements of whole blood glucose concentration and its calculated rate of rise or fall. In addition, various techniques are employed to compensate for measurement delay time and the presence of noise in the measured signals. The goal of these feedback systems is to normalize blood glucose in diabetes mellitus. Interestingly, some recently "optimized" versions provide only a near normalization of glycemia in patients with insulin-dependent diabetes, a degree ofglycemic control which is not significantly different from intensified conventional insulin therapy.
Comparative morphometric analysis of aggressive and ordinary basal cell carcinoma of the skin

A morphometric analysis was performed on histologic sections of 11 cases of aggressive basal cell carcinoma that recurred and/or metastasized after the first diagnosis (BCC2) and on 11 ordinary basal cell carcinomas (BCC1). The considered parameters were as follows: nuclear area, perimeter, maximum diameter, feret x, feret y, form perimeter, and form area. The results show numeric differences between the two groups for the first five parameters. A statistical analysis was performed between BCC1 and BCC2 for all the considered parameters using a two‐sided t test for independent samples. The test showed significant differences between the first five parameters except for the two form factors. A multivariate analysis was performed using area and perimeter values of the compared groups that amplified the discrimination threshold between the two groups. The authors conclude that a morphometric assessment may bring significant contribution in the knowledge and in the outcome prediction of basal cell carcinoma.
Discharge properties of motor units in relation to recruitment order in voluntary contraction.

The discharge pattern and recruitment order of single motor units in voluntary contraction of the normal human anterior tibial muscle was studied with an electrode having a high selectivity and a high positional stability in the muscle. In sustained contractions each motor unit was activated at a characteristic level of tension. The higher the threshold of the motor unit in sustained contraction, the higher was the frequency when the unit attained a discharge at regular intervals and the higher tended the “maximum frequency‘-of the unit to be. Motor units with low thresholds in sustained contractions exhibited a continuous or tonic discharge in strong sustained contractions, whereas units with high thresholds tended to exhibit a discontinuous or phasic discharge. For some units the threshold of activation remained stable, for others it increased during activity. In twitch contractions the recruitment order of motor units differed considerably from that in sustained contractions.
Internet Financial Reporting Adoption: Exploring the Influence of Board Role Performance and Isomorphic Forces

Purpose This study aims to examine the contribution of board role performance and isomorphic forces on internet financial reporting. Design/methodology/approach This study is cross-sectional and correlational. Data were collected through a questionnaire survey of 40 financial services firms. The study’s unit of analysis was a firm. Chief Internal Auditors and Chief Finance Officers were the study’s unit of inquiry. Data were analyzed through correlation coefficients and linear regression using Statistical Package for Social Sciences. Findings The results suggest that board role performance and isomorphic forces are significant predictors of internet financial reporting. However, board role performance is not a significant predictor of internet financial reporting in the presence of isomorphic forces. The control and strategic roles of the board are positively and significantly associated with internet financial reporting unlike the service role. Only the coercive isomorphism is positively and significantly associated with internet financial reporting unlike the normative and mimetic isomorphism. Originality/value This study provides initial empirical evidence on the contribution of board role performance and isomorphic forces on internet financial reporting using evidence from Uganda’s financial service firms. To the researcher’s knowledge, this is the first perception-based study on internet financial reporting.
Customer recognition and mobile geo-targeting

We focus on four important features of mobile targeting. First, consumers' real-time locations are known to sellers. Second, location is not the only factor determining how responsive consumers are to discounts. Other factors such as age, income and occupation play a role, which are imperfectly observable to marketers. Third, sellers may infer consumer responsiveness from their past purchases. Fourth, firms can deliver personalized offers to consumers through mobile devices based on both their real-time locations and previous purchase behavior. We derive conditions that determine how combining behavior-based marketing with mobile geo-targeting influences profits and welfare in a competitive environment. Our setting nests some earlier models of behavior-based price discrimination as special cases and yields additional insights. For instance, different from previous studies we show that pro.t and welfare effects of behavioral targeting may depend on firm discount factor.

Preliminary Study: Green Practices, Awareness and Knowledge about the Environment among Homestay Operators in Selangor, Malaysia

Homestays are a form of community-based tourism that offers local experiences of village lifestyle to travellers. In addition, it is a human-oriented services industry. Thus, any increase in tourist arrivals will affect this industry and in turn, the environment. In recent years, environmental issues have become among the most significant issues of concern in the world. Since the homestay industry contributes to environmental issues, especially through daily operations which involve a lot of resources, the Tourism Ministry of Malaysia has introduced new initiatives to raise awareness among entrepreneurs regarding the importance of environmental conservation. Therefore, this study explores the reliability and validity of green practices, as well as general level of awareness and knowledge about the environment among homestay operators. This preliminary study uses quantitative methods which include a questionnaire distributed to 100 respondents comprising homestay operators in Selangor, who are registered with the Malaysian Tourism Ministry. The reliability test and exploratory factor analysis of the items in the questionnaire was carried out using SPSS software and the results are expected to be used for further analysis. Keywords— homestay, green practices, awareness, knowledge, Malaysia

Based on the Swiss cheese theory, the study was designed to examine preventative measures that managers could implement to minimize the potential data breaches resulting from internal employees’ behaviors. The purpose of this study was to provide insight to managers about developing strategies that could prevent data breaches from cyber-threats by focusing on the specific internal human factors responsible for data breaches, the root causes, and the preventive measures that could minimize threats from internal employees. Data were collected from 10 managers and 12 employees from the business sector, and 5 government managers in Ivory Coast, Africa. The mixed methodology focused on the why and who using the phenomenological approach, consisting of a survey, face-to-face interviews using openended questions, and a questionnaire to extract the experiences and perceptions of the participants about preventing the adverse consequences from cyber-threats. The results indicated the importance of top managers to be committed to a coordinated, continuous effort throughout the organization to ensure cyber security awareness, training, and compliance of security policies and procedures, as well as implementing and upgrading software designed to detect and prevent data breaches both internally and externally. The findings of this study could contribute to social change by educating managers about preventing data breaches who in turn may implement information accessibility without retribution. Protecting confidential data is a major concern because one data breach could impact many people as well as jeopardize the viability of the entire organization.

A defect in skeletal muscle sodium channel deactivation exacerbates hyperexcitability in human paramyotonia congenita

1 Paramyotonia congenita (PC) is a human hereditary disorder wherein missense mutations in the skeletal muscle sodium channel lead to cold‐exacerbated muscle hyperexcitability. The most common site for PC mutations is the outermost arginine of domain IV segment 4 (human R1448, rat R1441). 2 We examined the rat homologues of two PC mutants with changes at this site: R1441P and R1441C. The R→P mutation leads to the most clinically severe form of the disease. Since PC has so far been attributed to defects in fast inactivation, we expected the R→P substitution to have a more dramatic effect on fast inactivation than R→C. Both mutants (R1441P and R1441C), however, had identical rates and voltage dependence of fast inactivation and activation. 3 R1441P and R1441C also had slowed deactivation, compared with wild‐type, raising the possibility that slowed deactivation, in combination with defective fast inactivation, might be a contributing cause of paramyotonia congenita. Furthermore, deactivation was slower in R1441P than in R1441C, suggesting that the worse phenotype of the human R→P mutation is due to a greater effect on deactivation, and supporting our hypothesis that slowed sodium channel deactivation contributes to paramyotonia congenita. 4 We show that the downstroke of the muscle action potential produced a sodium tail current, and thus slowed deactivation opposes repolarization and therefore leads to hyperexcitability. Hyperexcitability due to slowed deactivation, which has previously been overlooked, also predicts the temperature sensitivity of PC, which has otherwise not been adequately explained.
Conceptual Model of Predictors of SMEs' Performance in the Context of Sudan

Purpose: SMEsâ€™ performance in Sudan is in downturn and calls for research-based solution. To address this, this conceptual study proposes a model entailing management accounting practices (costing, budgeting, and performance measures practices) as predictors of SMEsâ€™ performance. Also, research findings on the relationship between management accounting practices and performance are inconsistent. & Given this, this study proposes a model entailing management accounting practices as determinants of SMEsâ€™ performance with moderating role of external business environment.Design/methodology/approach: This work is theorized based on extensive literature survey through which a conceptual model is developed and discussed. Inconsistent relationship between management accounting practices and performance is valuated and established via published research. Also, moderating role of external business environment is discussed and validated based on contingency theory.Findings: This paper proposes a conceptual model to serve as an answer to how Sudanese SMEsâ€™ performance can be improved through management accounting practices.Research limitations/implications: The proposed model in this work is based on survey of published research, but it can be empirically solidified further through collection and analysis of relevant data.Practical implications: The paper can help SMEsâ€™ owners/ managers and policy makers to understand how properly-adopted management accounting practices can improve SMEsâ€™ performance.Originality/value: The proposed conceptual framework is an exceptional and all-inclusive model that will expectantly improve the relevant body of literature and serve as useful guide for stakeholders on how the performances of SMEs can be boosted to enable them catch up with the SMEsâ€™ performance level of the developed countries in order to boost the economy of Sudan as a nation.
Photocatalytic degradation of Methylene blue dye and Chromium metal from wastewater using nanocrystalline TiO2 Semiconductor

This paper describes the basics of photocatalysis on semiconductors, mainly on TiO2 and the application of photocatalytic processes for water purification from organic and inorganic matter as well as metal removal introduced in order to improve the photocatalytic action of titanium dioxide. The photocatalytic activity of anatase phases of nanocrystalline TiO2 for the degradation of different substances under UV light irradiation. The higher phtocatalytic activity was obtained in anatase phase of TiO2. In the present investigation, result indicates that removal of dye methylene blue(MB) and metal chromium Cr (VI) has been studied by considering influent concentration, loading of photocatalyst, pH and contact time as operating variables. The percentage removal of dye MB and Cr(VI) increase with increase in contact time. The optimum contact time was fixed at 180 minutes for TiO2. The results of this study reveal that the dyes could be removed by semiconducting nanomaterials assisted photoatalytic degradation. The kinetics study of experimental data were analyzed using the pseudo first order kinetics of Lagergren and Pseudo second order model to determine adsorption rate constant. The semiconducting nano materials was charecterised by EDX, XRD and SEM for determining the contents and the size of particles.
Mood disorders: neurocognitive models

In recent years, a number of neurocognitive models stemming from psychiatry and psychology schools of thought have conceptualized the pathophysiology of mood disorders in terms of dysfunctional neural mechanisms that underpin and drive neurocognitive processes. Though these models have been useful for advancing our theoretical understanding and facilitating important lines of research, translation of these models and their application within the clinical arena have been limited—partly because of lack of integration and synthesis. Cognitive neuroscience provides a novel perspective for understanding and modeling mood disorders. This selective review of influential neurocognitive models develops an integrative approach that can serve as a template for future research and the development of a clinically meaningful framework for investigating, diagnosing, and treating mood disorders.
Modulation of Bcl‐2 expression: a potential component of estrogen protection in NT2 neurons

EUROPROTECTIVE effects of estrogen have been demonstrated against a variety of cytotoxic insults. We present data here addressing a possible mechanism of estrogen neuroprotection in the human teratocarcinoma cell line NT2 terminally differentiated to a neuronal phenotype. Cell death induced by H2O2 or glutamate results in a dose-dependent cell death of NT2 neurons, while 24 h of estrogen pretreatment significantly enhances neuronal viability. Bcl-2 expression has been shown to reduce oxidative stress and prevent cell death. In NT2 neurons, Bcl-2 levels are dramatically elevated upon differentiation and are further enhanced with estrogen treatment. These results suggest that neuroprotective effects of estrogen may be related to increases in Bcl-2 expression.
Classification of non‐well‐founded sets and an application

A complete list of Finsler, Scott and Boffa sets whose transitive closures contain 1, 2 and 3 elements is given. An algorithm for deciding the identity of hereditarily finite Scott sets is presented. Anti‐well‐founded (awf) sets, i. e. , non‐well‐founded sets whose all maximal ∈‐paths are circular, are studied. For example they form transitive inner models of ZFC minus foundation and empty set, and they include uncountably many hereditarily finite awf sets. A complete list of Finsler and Boffa awf sets with 2 and 3 elements in their transitive closure is given. Next the existence of infinite descending ∈‐sequences in Aczel universes is shown. Finally a theorem of Ballard and Hrbáček concerning nonstandard Boffa universes of sets is considerably extended.
Periodic biosynthesis of the human M-phase promoting factor catalytic subunit p34 during the cell cycle

The product of the CDC2Hs gene is the protein kinase subunit of the M-phase promoting factor, which is required for entry into mitosis. The activity of this kinase is regulated in a cell cycle-dependent manner by reversible phosphorylation and through association with other proteins. We report here that in HeLa cells, the abundance of the CDC2Hs mRNA and the rate of synthesis of the encoded protein, p34, vary in a cell cycle-dependent manner.
THE FACTORS THAT EFFECT ON INTERNAL AUDITOR INDEPENDENCE IN THE ACEH BANKING SECTOR

This study aimed to examine the factors that effect on internal auditor independence of the internal auditor, namely the competence of internal auditors, management intervention, employee participation and regulation of the company. The sample of this research is internal auditing staff at banks of Aceh. Data were collected through the distribution of questionnaires to respondents using multiple linear regression analysis. The results showed that all factors have influences on the independence of internal auditor, simultaneously or partially. While auditor competence, employee participation, and company regulation have positive influence, management intervention has a negative influence on the independence of the internal auditors.
Modeling the utilization of a multi-tenant band in 3GPP LTE system with Licensed Shared Access

Fueled by the rapid growth of mobile services, the actual demand for efficient sharing of available but underutilized frequency spectrum puts pressure on the responsible players (ITU, ETSI) to rethink the feasible ways of allocating wireless spectrum. Today, the LSA regulatory framework is considered to be an important enabler for optimized spectrum sharing between the incumbent and the LSA licensee (e.g., mobile network operator). At any point of time, the frequency bands can be utilized by only a single party, and the spectrum owner has priority in its usage at all times. In this paper, we introduce a mathematical and a system model for the multi-tenant band within the 3GPP LTE cellular network. As the main output of this work, the obtained numerical results for one multi-tenant band are produced. Said band is assumed to be intolerant to traffic delay and our results include the blocking probability as well as the mean downlink TX power of the eNodeB.
Begging for information: mother–offspring food sharing among wild Bornean orangutans

Transfer of solid food from mothers or other adults to dependent offspring is commonly observed in various primate species and both nutritional and informational benefits have been proposed to explain the function of such food sharing. Predictions from these hypotheses are tested using observational data on wild orangutans (Pongo pygmaeus wurmbii) at Tuanan, Central Borneo, Indonesia. In 1,145 hr of focal observation and 458 recorded food interactions between four pairs of females with offspring it was found that virtually all transfers were initiated by the offspring and that younger infants solicited food more often and did so for a greater variety of items than older offspring. All offspring primarily solicited food that was difficult to process, i.e., inaccessible to them. Furthermore, the amount of food solicitation was negatively correlated with ecological competence. Hence food sharing seemed to be related to an offspring's skill level, as suggested by the informational hypothesis. In contrast, offspring did not solicit high‐quality items more than low‐quality items and food sharing did not peak around the age of weaning, as predicted by the nutritional hypothesis. Mothers were usually passively tolerant, allowing offspring to take food but hardly ever provisioned. Parent–offspring conflict concerning food sharing was only observed well after weaning. Thus, by taking food directly from the mother, young orangutans were able to obtain information about the affordances and nutritional value of food items that were otherwise out of their reach and could familiarize themselves with the mother's diet. In species such as orangutans or other apes, characterized by a broad diet that requires extractive foraging, informational food transfer may be vital for an immature to acquire complex feeding skills and adult diet.
