Scheduling for long term proportional fairness in a cognitive wireless network with spectrum underlay

In this paper we study fair rate scheduling in an ad hoc cognitive wireless network with spectrum underlay. Transmissions in the network are allowed provided their interference to the primary network is below a predefined threshold. An optimal scheduling problem is formulated with an objective to achieve proportional fairness (PF) of the long-term average transmission rates among different links. Implementing the optimum scheduling requires high complexity. Two practical scheduling schemes are then proposed. In the first scheme, transmission priorities of the links are determined by their potential contributions to an objective utility function, assuming there is no co-channel interference within the network. In the second scheme, transmission priorities are derived from both the objective function and interference to the primary network. We also consider using exclusive regions to limit interference among simultaneous transmissions in order to improve the system throughput. The scheduling schemes can be implemented distributively in the ad hoc cognitive wireless network with limited assistance from the primary network. Our results show that the proposed PF scheduling schemes can achieve high overall throughput and close-to-optimum fairness, and using exclusive regions can improve the system utility without compromising the fairness performance.
Clinical performance of CGMS in type 1 diabetic patients treated by continuous subcutaneous insulin infusion using insulin analogs.

OBJECTIVE Performance criteria have been established for in vitro blood glucose monitoring, particularly for the self-monitoring of blood glucose using glucose meters. Devices intended for use in the future, such as the continuous glucose monitoring system (CGMS), should satisfy similar criteria, particularly in diabetic patients under intensive therapy. RESEARCH DESIGN AND METHODS The analysis was conducted on 18 type 1 diabetic patients (not controlled, HbA(1c) >7.5%) treated by external pump using insulin analogs. Each patient received a glucose sensor for 3 days during his/her hospitalization and was instructed in its operation. Medtronic criteria were used to determine the accuracy of the CGMS. In addition, the data were analyzed according to American Diabetes Association (ADA) criteria, Clarke Error Grid analysis, and method of residuals, with the glucose oxidase method using a Beckman analyzer used as the reference method. Specificity and sensitivity were evaluated from the viewpoint of accuracy in the detection of hypoglycemia. For nine patients, two glucose sensors were simultaneously inserted into an abdominal site to determine the reproducibility of the system. RESULTS-Among the 33 glucose sensors inserted, 6 (18%) were nonfunctional. The mean duration of CGMS recording was 63 +/- 12 h. From all of the 692 sets of data that paired glucose readings and CGMS, the coefficients of correlation ranged from 0.87 to 0.92 and the mean absolute error ranged from 12.8 to 15.7%. The time experienced in hypoglycemia (<55 mg/dl) was reported at 86 +/- 62 min/day. Only 39% of the CGMS values satisfied the ADA precision criteria to within +/-10%, and 19% of these values satisfied the future ADA precision criteria of accuracy to within +/-5%. The means of difference method showed that the CGMS slightly underestimated the plasma glucose values (mean = -12 mg/dl). Error grid analysis showed only 77% of the glucose sensor values were in zone A, and 98.9% were in zones A and B. Two values fell in zone C and a single value fell in zone D. The sensitivity and specificity of the CGMS to detect hypoglycemia were 33 and 96%, respectively. A total of 6666 paired sensor values were recorded with a coefficient of correlation of 0.84 with a coefficient of variation of 8.25%. CONCLUSIONS CGMS could be useful in routine clinical practice to provide much more information on the glucose profile than intermittent self-monitoring of blood glucose (SMBG). However, CGMS cannot be used as a replacement for glucose meters because it does not satisfy the conventional performance goals set down for in vitro glucose measurements and could therefore lead to clinically incorrect treatment decisions.
Chemoreception in a marine cryptophyte: Behavioral plasticity in response to amino acids and nitrate

The behavioral responses of Chroomonas sp. to ammonium, nitrate, and 19 individual amino acids were examined by computer‐assisted video motion analysis. Cells were cultured with either glycine or nitrate as the sole nitrogen source. Relative to seawater, rates at which glycine‐grown cells stopped and turned were significantly reduced in response to 10−6 and 10−7 M glutamate, methionine, alanine, and aspartate. This response was akin to the tumbling behavior (chemotaxis) displayed by flagellated bacteria. When cultured in nitrate, Chroomonas sp. did not react to amino acids and ammonium but did significantly reduce stopping and turning in response to 10−6 M nitrate. These results are the first to demonstrate chemoreception in any cryptophyte species. Because Chroomonas sp. commonly lives in habitats where light and inorganic nutrients are limiting, behavioral mechanisms that maximize use of both amino acids and nitrate would seem particularly adaptive.
Parametric Study of Neural Gastric Electrical Stimulation in Acute Canine Models

Manipulation of gastric motility by gastric electrical stimulation (GES) has been suggested as a minimally invasive alternative treatment of gastric motility disorders and obesity. However, only neural GES (NGES) has been successful in invoking gastric contractions. Nevertheless, the relationship between these contractions and the controlling NGES parameters has not been quantified. We aimed at determining the relationship between the electrical energy delivered to the tissue as a function of NGES parameters, and the strength and duration of the resulting invoked gastric contractions. Five healthy mongrel dogs underwent subserosal prepyloric implantation of two NGES electrode pairs. Gastric motility was captured by a force transducer implanted in the vicinity of the distal pair of stimulating electrodes. Custom-designed implantable stimulator delivered NGES with 8-16 V (peak-to-peak) amplitudes, and 60-100% duty cycles. Normalized motility index (MI) was utilized to quantify the contractions recorded from the force transducer. The MI increased with increasing voltage amplitudes. However, it remained remarkably constant across all duty cycles when voltage was held constant. Calculated motility generation efficiency indices (MGEI) indicated that highest energy efficiency for invoked motility was achieved at the lowest duty cycle. The parametric data obtained in the present study can be utilized to optimize the power efficiency of implantable gastric neurostimulators
Voices of Teacher Candidates: Positive Changes in Multicultural Attitudes and Knowledge

Abstract The author explored changes in teacher candidates' multicultural attitudes and knowledge as well as the factors that contributed positively to those changes. Teacher candidates were followed during their teacher preparation program. Data were collected from 2 questionnaires and 9 interviews. The author used repeated measures analysis and percentages to explore changes in multicultural attitudes and knowledge. She also used percentages to identify factors that the participants believed influenced those changes. Findings suggest that teacher candidates' multicultural attitudes and knowledge changed in a positive direction while the candidates attended a teacher preparation program. Changes seemed to be influenced by fieldwork experiences in culturally/ethnically diverse settings, courses in multicultural and bilingual education, and classmates.
Novel Proximal 14q Deletion: Clinical and Diffusion Tensor Imaging Tractography Findings in a Patient with Lissencephaly, Agenesis of the Corpus Callosum, and Septo-Optic Dysplasia

SUMMARY: We report the unique CNS findings in a patient with a proximal chromosome 14q interstitial deletion. Conventional MR imaging allowed the clear delineation of agenesis of the corpus callosum, SOD, and diffuse lissencephaly. DTI tractography played a significant role in the evaluation of the proximal 14q deletion−associated abnormalities, delineating the extent of the dysmorphic connections of the Probst bundles and clarifying that apparent areas of heterotopias were the corticospinal tracts.
TERT Polymorphism rs2736100-C Is Associated with EGFR Mutation–Positive Non–Small Cell Lung Cancer

Purpose: EGF receptor (EGFR) mutation–positive (EGFRmut+) non–small cell lung cancer (NSCLC) may be a unique orphan disease. Previous studies suggested that the telomerase reverse transcriptase (TERT) gene polymorphism is associated with demographic and clinical features strongly associated with EGFR mutations, for example, adenocarcinoma histology, never-smoking history, and female gender. We aim to test the association between TERT polymorphism and EGFRmut+ NSCLC. Experimental Design: We conducted a genetic association study in Chinese patients with NSCLC (n = 714) and healthy controls (n = 2,520), between the rs2736100 polymorphism and EGFRmut+ NSCLC. We further tested the association between the EGFR mutation status and mean leukocyte telomere length (LTL). The potential function of rs2736100 in lung epithelial cells was also explored. Results: The rs2736100-C allele was significantly associated with EGFRmut+ NSCLC [OR, 1.52; 95% confidence interval (CI), 1.28–1.80; P = 1.6 × 10−6] but not EGFRmut− NSCLC (OR = 1.07, 95% CI, 0.92–1.24, P = 0.4). While patients with NSCLC as a whole have significantly longer LTL than healthy controls (P ≤ 10−13), the EGFRmut+ patients have even longer LTL than EGFRmut− patients (P = 0.008). Meanwhile, rs2736100 was significantly associated with TERT mRNA expression in both normal and tumor lung tissues. All results remained significant after controlling for age, gender, smoking status, and histology (P < 0.05 for all tests). Moreover, the rs2736100 DNA sequence has an allele-specific affinity to nuclear proteins extracted from lung epithelial cells, which led to an altered enhancer activity of the sequence in vitro. Conclusions: Our study suggests that telomerase and telomere function may be essential for carcinogenesis of EGFRmut+ NSCLC. Further investigation for the underlying mechanism is warranted.

Survival and prognostic factors of HIV-infected patients with HCV-related end-stage liver disease

Objective:To find the survival and the predictors of death of HIV-infected patients with hepatitis C virus (HCV)-related end-stage liver disease (ESLD). Design and methods:A prospective cohort study set in the infectious diseases units of four tertiary care public hospitals in Andalucía, Spain. From a multicentric cohort of 2664 HIV/HCV-co-infected patients, all consecutive patients with HCV-related cirrhosis who presented with the first hepatic decompensation from January 1997 to June 2004 were followed-up and 153 patients were included. The survival and the demographic, HIV-related and liver-related factors associated with death were evaluated. Results:Ninety-five (62%) patients died during the follow-up. In 79 (85%) individuals, the cause of death was liver related. The median survival time was 13 months. Independent predictors of survival were Child score [hazard ratio (HR), 1.2; 95% confidence interval (CI), 1.08–1.37; P = 0.001], CD4+ cell count at decompensation lower than 100 cells/μl (HR, 2.48; 95% CI, 1.52–4.06; P < 0.001) and hepatic encephalopathy as the first hepatic decompensation (HR, 2.45; 95% CI, 1.41–4.27; P = 0.001). HAART was prescribed to 101 (66%) patients. The cumulative probability of survival in patients under HAART was 60% at 1 year and 40% at 3 years, versus 38 and 18%, respectively, in patients not treated with HAART (P < 0.0001). The HR (95% CI) of death in patients on HAART was 0.5 (0.3–0.9), (P = 0.03). Conclusions:The survival of HIV/HCV-co-infected patients with ESLD is extremely poor. Immunosuppression and markers of severe liver disease predict liver-related mortality in these patients. HAART seems to be associated with a reduced liver-related mortality.
This Business of Internationalization: The Academic Experiences of 6 Asian MBA International Students at the University of Minnesota’s Carlson School of Management

Conducted in the spring of 2000, this study looked at the academic experiences of 6 Asian international students at the University of Minnesota’s Carlson School of Management (CSOM). The research employed the case study methodology, with interviews, a classroom observation, and situational recall questionnaires as methods of data collection. The findings indicated culture shock, language barriers, and education shock as variables affecting the adjustment of these students, and are congruent with previous studies in this area. Students desired more preparation for academic expectations as well as the social environment before and during their studies at CSOM. They also asserted the need for increased international interest at CSOM.
What Families Need: Validation of the Family Needs Assessment for Taiwanese Families of Children with Intellectual Disability and Developmental Delay

This study documented the process of developing and validating the Family Needs Assessment (FNA), a seven-factor 73-item measure developed for research and practice, using a sample of Taiwanese families. In developing the FNA, the research team identified a theoretical basis for family needs, used literature and qualitative results in generating items, ensured culturally and linguistically accurate translation of the measure, and revised the measure based on results from pilot tests and cognitive interviews. Although a confirmatory factor analysis is necessary to support final validity, results from this study provide a foundation for understanding Taiwanese family needs. According to the results, the domains with highest needs are Hope (i.e., anticipating and achieving positive outcomes) and Disability-Related Services (i.e., getting services and teaching the child with disabilities). Findings from this study indicate that the FNA, developed as a comprehensive, contemporary, accessible, and culturally appropriate tool, can contribute to the disability-related field in research and practice.
Relational Maintenance during Military Deployment: Perspectives of Wives of Deployed US Soldiers

This manuscript is one of many in a special issue of the Journal of Applied Communication Research on “Communication and Distance,” Volume 38, No. 1. Deployment-based separations, during which military spouses' communication is limited and their uncertainty heightened, present numerous challenges to spouses' enactment of relational maintenance. To better understand how partners maintain relationships during deployment, this study analyzes interviews with 33 wives of deployed US service members. Content analysis yielded 24 forms of relational maintenance. Results also indicated factors that potentially shape and complicate maintenance performance, such as restrictions on the amount, timing, and content of communication. Rather than demonstrating universally effective patterns of maintenance, results suggest that spouses enact maintenance commensurate with their individual needs and resources. The author speculates that during deployment separations, spouses potentially negotiate an interplay in their relational maintenance between, on the one hand, careful planning and, on the other hand, creative improvisation.
Factor V Leiden, Prothrombin and MTHFR Mutation in Patients with Preeclamsia, Intrauterine Growth Restriction and Placental Abruption

BACKGROUND: Factor V Leiden, Prothrombin and MTHFR gene mutation, could have an influence in pregnancy with adverse outcome Preeclamsia, IUGR and Placental abruption. AIM: The aim of this study is to investigate the presence of above mentioned inherited thrombophilias and its statistical significance, distribution among the complicated and normal pregnancy, and relative risk for carrier of mutation to develop preeclampsia, IUGR and placental abruption. MATERIAL AND METHODS: Prospective cohort study is implemented at University Clinic for Obstetric and Gynecology in Skopje, Republic of Macedonia. The study included 109 delivered patients: 40 with preeclapmsia, 22 with IUGR, 17 with placental abruption and 30 as control group with normal pregnancy. The amount of 3 ml venous blood has been used for detection of these point mutations using ThromboStrip -Opegen, QIAGEN kit manufactured for thrombotic risk. RESULTS: The highest frequency was found: in the group with preeclampsia 35% were MTHFR homozygous, IUGR -MTHFR heterozygous 45%, Placental abruption- 52.9% MTHFR heterozygous, and in the control group without thrombophilia 56.7%. There were combined thrombophilia in 3 patients. There aren`t statistical significance in presence of thrombophilia among groups (p > 0.05). Statistical significance (p < 0.05) was found between carriers of MTHFR homozygous in preeclampsia and group with placental abruption and control group. Relative risk in IUGR group for MTHFR homozygous was 5.54 (1.37<RR<22.4). Relative risk in placental abruption for Factor V Leiden heterozygous was 4.50 (0.47<RR<42.75). CONCLUSION: The presence of mutation MTHFR homozygous could increase the risk for development of IUGR and mutation of Factor V Leiden for placental abruption. Further investigations with more patients are warranted.
Brand Advocacy and Sales Effort by Retail Salespeople: Antecedents and Influence of Identification with Manufacturers’ Brands

Retail salespeople represent an important link for manufacturers in communicating value propositions to retail customers and for implementing target market strategies. Past research reveals that the recommendations provided by retail salespeople exert significant influence on customers’ brand choice, especially in the context of consumer durables. However, as the retail environment is often characterized by an inherent tension between manufacturer and retailer strategies, a major challenge for manufacturers is to induce retail salespeople to recommend their brands over those of rivals. Relationship marketing and social identity theory suggest that psychological attachments motivate the direction and intensity of individuals’ volitional efforts and extra-role behaviors. Extending past research, this study examines brand identification among retail salespeople as a critical psychological mechanism that mediates the influence of manufacturer and manufacturer representative–related factors on brand advocacy and sales effort. Using data gathered from retail salespeople employed in the consumer durables division of a major national retailer, a framework integrating the antecedents and outcomes of brand identification is tested. Based on the study’s results, implications for theory, manufacturers, and retailers are offered.
Uncertainty Amidst Change: The Impact of Privatization on Employee Job Satisfaction and Well-Being

The literature on the effects of critical life-events on health and well-being has remained prolific since Holmes & Rahe’s (1967) formative work on their development of the Social Readjustment Rating Scale. Since then, credence has generally been given to the view that favourable perceptions of major life-events may evoke different reactions to those viewed negatively. The original premise made no distinction between uplifts and downfalls, and viewed individuals as passsive homogeneous victims of life’s ‘slings and arrows’, without any volition to act on the environment which caused such hardship. Holmes & Masuda (1974) developed this work further and constructed their ‘Schedule of Recent Experiences’ (SRE) which not only asked whether subjects had experienced a specific event, but also asked on how many occasions that event was experienced. The likelihood of more extreme events occurring on more than one occasion in the recent past are rare (e.g. death of a spouse). The underlying proposition behind this seminal work, that major changes in our daily lives are shown to increase the probability of illness, has yet to be effectively disconfirmed (Bhagat 1983, Billings & Moos, 1982).
Magnetoelastic coupling in rotating electrical machines

This paper presents a method for the calculation of vibrations in rotating electrical machines when the magnetoelastic coupling is to be taken into account. A dynamic model for the magnetoelastic coupling is presented, where the circuit equations for windings of the machine are also coupled with the magnetic field. Calculation results for coupled and uncoupled cases are compared. It is shown that the calculated vibrations of the stator of a synchronous generator are different when the coupling is taken into account. Depending on the considered vibration frequency, an increase or decrease of the amplitudes of vibrations of about 20% is noticed due to the magnetoelastic coupling. This phenomenon has to be accounted for when modeling the vibrations of large stator cores, which are not very stiff mechanically.
Humiliation, loss and other types of life events and difficulties: a comparison of depressed subjects, healthy controls and their siblings

Background. It has been proposed that adverse life events involving loss or humiliation are particularly potent in provoking depressive episodes. We have also previously suggested that experiencing high rates of non-severe events may play a role in the development of resilience to the impact of severe threatening events when these occur. Method. The Life Events and Difficulties Schedule (LEDS) (Brown & Harris, 1978) was used to record the life events experienced by 108 depressed probands and their nearest aged siblings as well as 105 healthy control subjects and their nearest aged siblings. All subjects were interviewed using the Schedule for the Clinical Assessment of Neuropsychiatry (SCAN) (Wing et al. 1990). Results. Depressed probands were significantly more likely to have experienced a severe threatening event, loss event, or a humiliation event compared to the other subjects. These events also made up a greater proportion of the total number of events, in the depressed probands. Humiliation events were more frequent in depressed men than depressed women. There were no differences between the four groups for experiencing a non-severe event, although depressed probands also experienced more difficulties than the other three groups. Fifty-six healthy subjects who had not become depressed despite having experienced at least one severe and threatening event, had significantly more non-severe events, than the 116 subjects who were depressed at the time of interview. Conclusions. The findings support the hypothesis that loss and humiliation events are particularly depressogenic. Experiencing a high rate of non-severe events may be associated with resilience to becoming depressed in the face of a threatening event.
PENGARUH STRATEGI KNOW-WANT TO KNOW-LEARNED (K-W- L) DAN MOTIVASI BELAJAR TERHADAP KEMAMPUAN MEMAHAMI HIKAYAT SISWA KELAS X DI SMA ISLAM AZ- ZAHRA PALEMBANG 1

The purpose of the study was to see the influence of K-W-L strategy and learning motivation toward the student’s ability to comprehend the legends. The participants of study were 50 students who were taken from X1 and X3 classes. The data was obtained by administering the objective test and distributing the questionnaires. The data was analyzed using t-test and anova. Based on the data analysis, it was found the use of KWL strategy and learning motivation did not provide a positive influence on students’ ability to comprehend the legends. Thus, generally this study only affected by the learning motivation. Learning motivation held an important role in the process of learning the legend well. Keywords: K-W-L strategy, learning motivation, and the abiliy to comprehend the legends.
