Analysis of Urban Two-Tier Heterogeneous Mobile Networks With Small Cell Partitioning

In this paper, we investigate the performance of typical indoor users in urban two-tier heterogeneous mobile networks with indoor-deployed small cell base stations (BSs) and outdoor BSs. The urban topology is modeled by a Boolean scheme of blockages, which is tied together with the deployment of outdoor and indoor BSs as well as the signal propagation characteristics. Each building is assumed to be served by an indoor small cell BS with a certain probability, which is denoted as occupation probability. Indoor and outdoor environments are partitioned by walls with a certain penetration loss. We separately account for outdoor BSs in line of sight (LOS) and non-line of sight (NLOS), as well as small cell BSs in neighboring and non-neighboring buildings. We derive expressions for the signal to interference ratio (SIR)-coverage probability and the average spectral efficiency of a typical indoor user. Numerical evaluations are performed with 3GPP compliant macro- and pico-BS scenarios. Our results exhibit that the indoor area coverage, which is a function of the building density and size, significantly affects the impact of the target building's wall penetration loss. The analysis is simplified by various assumptions, which are verified by extensive Monte Carlo simulations.
Treatment of β-Thalassemia Patients with Recombinant Human Erythropoietin: Effect on Transfusion Requirements and Soluble Adhesion Molecules

The most common single genetic disorder and a major public health issue in Greece and other Mediterranean countries is β-thalassemia. Current therapeutic approaches for homozygous β-thalassemia entail blood transfusions and iron chelation therapy with deferoxamine or deferiprone for preventing tissue hemosiderosis. Recently, much effort has focused on various inducers of fetal hemoglobin (HbF) such as recombinant human erythropoietin (rHuEPO), especially in β-thalassemia intermedia. Ten adult patients, 5 with β-thalassemia major and 5 with β-thalassemia intermedia, received 150 IU/kg rHuEPO (epoetin-α) subcutaneously three times a week. Seven patients were transfused every 14–30 days and 3 with β-thalassemia intermedia were only occasionally transfused. The minimum duration of treatment was 12 weeks in order to define if there was any response. Transfusion intervals were modified according to the rHuEPO response to maintain stable Hb values. Lower transfusion requirements were observed in 5 patients after rHuEPO treatment (p = 0.028). In the 3 non-transfused patients, Hb values increased, and the patients are still being treated and followed up for a period ranging from 14 weeks to 2 years. Two patients with thalassemia major discontinued treatment after 12 weeks, as they did not achieve any response regarding transfusion requirements or Hb values. Pretreatment serum transferrin receptor levels were higher than in controls (p < 0.001) and significantly increased following rHuEPO treatment (p = 0.027). Patients had higher serum endothelin-3, sICAM-1 and sE-selectin values before rHuEPO treatment compared to controls (p < 0.001, p < 0.001 and p = 0.016, respectively), but these values were not altered during treatment. HbF values presented a slight, non-significant increase. rHuEPO treatment has a beneficial effect in transfusion-dependent β-thalassemia patients. Although a slight increase in HbF levels was observed, other possible mechanisms are probably involved. None of our patients experienced thrombotic complications and a rise in blood pressure.
Motivational Antecedents of Well-Being and Health Related Behaviors in Adolescents

Abstract Grounded in the Achievement Goal Theory framework of motivation and optimal functioning, there were two objectives of this study: (a) to test a model hypothesizing links between personal theories of school achievement, indices of the quality of academic engagement, wellbeing, and health-related behaviors, and (b) to explore whether the hypothesized model was invariant across gender groups. A multisection questionnaire pack tapping the targeted variables was administered to 967 teenagers (475 boys and 492 girls) aged between 11 to 16 years old. Structural equation modeling analysis revealed that Task theory of achievement predicted positively satisfaction in school and negatively boredom in school. An Ego theory of achievement was linked to higher levels of boredom in school. Satisfaction in school corresponded to higher life satisfaction, while boredom was negatively related. Higher life satisfaction was associated with lower tobacco, alcohol and marijuana consumption, more healthy food intake and greater levels of physical activity. The results revealed partial invariance of the model by gender. The quality of adolescents’ involvement in the classroom holds important implications for adolescent’s well-being and their health related behaviors. Interventions on the creation of a task-involving motivational climate in the school are proposed to promote healthy lifestyles among young people.
Efficacy of Chlorhexidine, Polihexanide and Tissue-Tolerable Plasma against Pseudomonas aeruginosa Biofilms Grown on Polystyrene and Silicone Materials

Background: The formation of biofilms is crucial in the pathogenesis of many acute and subacute microbial infections, including chronic wounds and foreign-body-related infections. Topical antimicrobial therapy with chemical antiseptics or physical treatment with tissue-tolerable plasma (TTP) may be promising to control bacterial infection. Methods: We assessed the efficacy of 0.1% chlorhexidine digluconate (CHX), 0.02 and 0.04% polihexanide (polyhexamethylene biguanide, PHMB) and of TTP against Pseudomonas aeruginosa SG81 biofilm grown in microtitre plates (polystyrene) and on silicone materials in an artificial wound fluid. Results: Overall, PHMB was as effective as CHX in reducing the total amount of biofilm (gentian violet assay) and in reducing the bacterial metabolism in biofilms (XTT assay). TTP also led to a significant reduction in colony-forming units. Conclusion: The antimicrobial activity of PHMB in biofilms is comparable to that of CHX. TTP could become an interesting physical alternative to chemical antisepsis in the future.
Isoflurane, Halothane, and Regional Cerebral Blood Flow at Various Levels of PaCO2 in Rabbits

The effects of halothane and isoflurane on regional cerebral blood flow (CBF) were studied in 18 New Zealand White rabbits anesthetized with nitrous oxide (N2O) and morphine sulfate (MS) at three different levels of Paco2. CBF was measured using the hydrogen clearance technique. Monitored variables were intracranial pressure (ICP), central venous pressure, heart rate, mean arterial pressure, electroencephalogram, arterial blood gases, end-tidal (ET) volatile anesthetic, and ET CO2. Addition of 1 MAC halothane to the N2O/MS background anesthetic caused flow to increase significantly in all three regions studied (cortex, dorsal hippocampus, white matter) at all three levels of Paco2 (low: 20–25 mmHg; normal: 35–40 mmHg; high: 50–55 mmHg). Addition of 1 MAC isoflurane to the background anesthetic caused CBF to decrease significantly in all regions during hypocapnia. During normocapnia, CBF was unchanged with the addition of 1 MAC isoflurane in all regions and during hypercapnia, CBF increased significantly only in the dorsal hippocampus following addition of 1 MAC isoflurane to the MS/ N2O background anesthetic. Volatile anesthetic administration was associated with significant, although small, increases in ICP at all Paco2 levels. We conclude that 1 MAC concentrations of halothane and isoflurane have opposite effects on CBF when added to a N2O/ MS anesthetic during hypocapnia and that the effects of isoflurane on regional CBF are dependent on Paco2 in rabbits under the anesthetic conditions of this experiment.
Public Funding of Charities and Competitive Charity Selection

Evidence on the price elasticity of private donations to charities and on the crowding out effect of donations by government grants suggests that a redirection of government funds from tax incentives for giving towards direct grants could increase total charity funding. This raises the question of why tax incentives for giving are used instead of direct grants. This paper shows that if government grants to charities face verification constraints, switching from direct grants to donation incentives can produce a pro-competitive effect on charity selection, raising the value of charity provision per dollar of funding.
The motivation of masons in the Sri Lankan construction industry

This research is an empirical study of human resource management (HRM) for the motivation of masons in the Sri Lankan construction industry (SLCI). The structured interview was chosen as a main research instrument for data collection. 90 masons and 30 supervisors were randomly selected from 10 construction sites within the SLCI. The study’s findings show that the supervisors and masons in the construction industry (CI) in Sri Lanka are aware of the supposed advantages of staffing, employee development and the rewards of a HRM approach. However, these characteristics have yet to play a significant role in the motivation of Sri Lankan supervisors and masons. A contextually sensitive application of these three strategies has the potential to improve motivation of the Sri Lankan construction workforce.
The Use of the Patient Health Questionnaire–9 Korean Version (PHQ-9K) to Screen for Depressive Disorders Among Korean Americans

The purpose of this study was to evaluate the utility of a translated instrument to screen for depressive disorders among Korean Americans (KAs). The Patient Health Questionnaire– (PHQ-9) was selected and translated into Korean (PHQ-9K). Two research questions were formulated: What is the prevalence of depression as determined by using the PHQ-9K among KAs attending a community-based health fair? Is this Korean-translated version of the PHQ-9K tool useful in screening for depression in KAs? Data were collected at an annual KA Community Medical Health Fair and analyzed following the guidelines for interpreting the PHQ-9. The results demonstrated that 15.4% of sample participants might need treatment for depression depending on the duration of symptoms, severity, and functional impairment, and 7.5% of participants definitely required treatment for depressive symptoms. The usefulness of the PHQ-9K to screen for depressive disorders in KAs at a primary care setting was confirmed.
Starvation Response of the Marine Barophile CNPT-3

The psychrophilic marine barophile CNPT-3 underwent a starvation-survival response similar to that reported for the marine bacteria Ant-300, DW1, and S-14. The number of culturable cells increased initially and then decreased gradually over a 24-day starvation period, with corresponding decreases in total cell number and direct viability count. A significant reduction in cell size and biovolume accompanied these changes. Starved cells demonstrated a greater tendency to attach at the in situ pressure (400 atm; ca. 40.5 MPa) and temperature (5°C) than at 1 atm (ca. 101 kPa), and the extent of attachment increased with increasing duration of starvation. The membrane fatty acid profile of the marine barophile CNPT-3 was studied as the cells were subjected to starvation conditions. A 37.5% increase in saturated fatty acids was observed during the first 8 days of starvation, with a concomitant decrease in unsaturated fatty acids. There was also an increase in the amount of short-chain (
Mammary ductal carcinoma in Situ with microinvasion

The natural history of patients with intraductal carcinoma (DCIS) and microinvasion is poorly defined, and the clinical management of these patients, with particular reference to management of the axilla, has been controversial. Previous studies of this lesion have used varied and/or arbitrary criteria for the evaluation of microinvasion.
A cis-acting element in the promoter region of the murine c-myc gene is necessary for transcriptional block

A block to elongation of transcription has been shown to occur within the first exon of the human and murine c-myc genes. The extent of this block was found to vary with the physiological state of cells, indicating that modulation of the transcriptional block can serve to control the expression of this gene. To determine which sequences are required in cis for the transcriptional block, we generated a series of constructs containing various portions of murine c-myc 5'-flanking and exon 1 sequences. We established populations of HeLa and CV-1 cells stably transfected with these constructs. The transcription start sites were determined by S1 nuclease mapping analysis, and the extent of transcriptional block was measured by nuclear run-on transcription assays. Our results demonstrate that at least two cis-acting elements are necessary for the transcriptional block. A 3' element was found to be located in the region where transcription stopped and showed features reminiscent of some termination sites found in procaryotes. A 5' element was positioned between the P1 and P2 (C. Asselin, A. Nepveu, and K. B. Marcu, Oncogene 4:549-558, 1989). Removal of the more 3' binding site abolished the transcriptional block.

The relationship of strength to function in the older adult.

Reduced lower extremity strength has been associated with reduction in gait speed, balance, stair-climbing ability, and getting up from a seated position. The relationship of lower extremity strength and the ability to accomplish selected functional activities was examined in 16 healthy but frail older adults ranging in age from 75 to 88 years (mean = 80.9 years). The following measures were obtained for each subject: preferred gait speed under laboratory and free walking conditions, 5 timed chair stand-ups, and time to complete an obstacle course. Strength measures of the hip extensors, hip abductors, knee extensors, planter flexors, and dorsiflexor muscle groups were obtained using a hand-held dynamometer. The relationship between the time to complete the functional activities and each of the strength variables was determined using Pearson product moment correlations. In addition, performance was examined in relation to various combinations of strength measures (e.g., hip and knee extension). Weak, nonsignificant hip, knee and ankle strength/functional activity relationships were found for all of the variables examined. When hip extension, knee extension, and ankle plantar flexion strength values were combined and normalized to body weight, a significant strength-to-functional activity relationship was found for 14" chair stand-ups (r = .636, p < .01). When values for quadriceps strength and gait speed for 35 adults ranging in age from 60-72 years were compared to those for 75-88 year olds, marked differences emerged. A more significant relationship between knee extension force and gait speed was observed for the younger adults (r = .528 vs r = .353). (ABSTRACT TRUNCATED AT 250 WORDS)
Toxicity of Cassia and Cinnamon Oil Compounds and Cinnamaldehyde-Related Compounds to Sitophilus oryzae (Coleoptera: Curculionidae)

Abstract The toxicity to adult Sitophilus oryzae (L.) (Coleoptera: Curculionidae) of two cassia oils (Especial and true), four cinnamon oils (technical, #500, bark, and green leaf), and (E)-cinnamaldehyde and its 41 structurally related compounds was examined by residual and vapor-phase toxicity bioassays. Results were compared with those of dichlorvos. In residual bioassays, cassia and cinnamon oils exhibited good insecticidal activity. Based on 48-h LD50 values, the toxicity of allyl cinnmate (0.0003 mg/cm2) was comparable with that of dichlorvos (0.00025 mg/cm2). Potent insecticidal activity also was observed with benzaldehyde, β-caryophyllene, cinnamonitrile, hydrocinnamyl acetate, (E)-4-hydroxycinnamic acid, and α-terpineol (LD50 = 0.003–0.009 mg/cm2). Structure–activity relationships indicate that types of functional groups rather than hydrophobicity or vapor pressure parameters seem to play a role in determining the toxicities to adult S. oryzae. In vapor-phase toxicity tests with weevils, these compounds were more effective in closed containers than in open ones. These results indicate that the effect of the compounds was largely a result of action in the vapor phase. Cassia and cinnamon oils and test compounds described merit further study as potential fumigants for the control of S. oryzae because of their greater activity as a fumigant.
A power scalable and high pulse swing UWB transmitter for wirelessly-powered RFID applications

This paper presents a 3-5 GHz, high output amplitude, carrier-less based Ultra Wideband (UWB) transmitter for wirelessly powered RFID application. The UWB transmitter consists of a baseband pulse generator, a driver amplifier and an output on-chip filter. The baseband pulse generator and the driver amplifier are designed as zero DC power consuming circuit, which enables scalable power with the pulse rate. IC pad and bonding wire parasitics are considered to be absorbed as part of output filtering network, realizing package co-design. The simulation result shows that the proposed transmitter radiates 2.34 pJ/pulse energy with 1.63 V pulse amplitude. The total energy consumption under 1.8 V power supply is 18 pJ/pulse, corresponding to 13% energy efficiency.
Implications of cognitive and affective mechanisms for interpersonal exchange relationships in teams

In this study, we investigated the effect of leader-member exchange (LMX) on team-member exchange (TMX), and tested the meditation effects of social identification and positive affect in the relationships between LMX and TMX. Our sample comprised of 291 front-line employees working within local branches of an Australian banking organisation. Results showed that LMX was positively related to social identification, positive affect, and TMX. We found further that social identification and positive affect mediated relationships between LMX and TMX. Our findings suggest that employees enjoying high-quality LMX relationships tend to develop high-quality TMX relationships; and that this is because they socially identify with their work groups, and experience positive emotions in the relationships that strengthen their relationships with other team members.

Restoration of Seagrass Habitat in New Jersey, United States

Abstract Seagrass restoration has often not been successful due to poor site planning, physical disturbance, transplant timing incompatibility, and physical and biological disturbances. As such, these factors are important for successfully restoring seagrasses, and global success has greatly increased. We conducted restorations in the mid-Atlantic region of the United States to reestablish this valuable habitat. Our restoration efforts in New Jersey involved transplants of both Zostera marina (eelgrass) and Ruppia maritima (widgeon grass). We found that Z. marina site success and transplant survival increased over the scope of this 4-year investigation (66%–100% and 34%–43%, respectively). However, R. maritima success was heavily dependant upon the year planted; with limited success in 2002 (12%) and high success during 2003 (80%), most likely related to the brown-tide bloom and nonbloom associated with these planting years. For both species restored, ecosystem function was becoming established by the end of the study, demonstrated by their ability to trap and bind fine particulate matter. We provide evidence from this study that seagrass restoration is a viable option for coastal managers and that once established, seagrasses can recover and expand.
Chinese guidelines on the management of renal cell carcinoma (2015 edition).

The guideline was established by the kidney cancer panel under the Chinese Society of Clinical Oncology (CSCO) in accordance with the basic principles of evidence-based medicine ( Table 1 ) and the clinical practices on renal cancer in China, based on the real conditions of China, and by referring to the USA NCCN Clinical Practice Guidelines in Oncology-Kidney Cancer (1) and the European Association of Urology (EAU) Guidelines on Renal Cell Carcinoma (2). The renal cancer referred in these guidelines is the renal cell carcinoma (RCC) and does not include various tumors originated from renal interstitium and renal pelvis/urothelial system.
Application of a mass-balance model to a Himalayan glacier

Abstract A mass-balance model based on the energy balance at the snow or ice surface is formulated, with particular attention paid to processes affecting absorption of radiation. The model is applied to a small glacier, Glacier AX010 in the Nepalese Himalaya, and tests of its mass-balance sensitivity to input and climatic parameters are carried out. Calculated and observed area-averaged mass balances of the glacier during summer 1978 (June-September) show good agreement, namely -0.44 and -0.46 m w.e. , respectively. Results show the mass balance is strongly sensitive to snow or ice albedo, to the effects of screening by surrounding mountain walls, to areal variations in multiple reflection between clouds and the glacier surface, and to thin snow covers which alter the surface albedo. In tests of the sensitivity of the mass balance to seasonal values of climatic parameters, the mass balance is found to be strongly sensitive to summer air temperature and precipitation but only weakly sensitive to relative humidity.
Improved visual speech synthesis using dynamic viseme k-means clustering and decision trees

We present a decision tree-based viseme clustering technique that allows visual speech synthesis after training on a small dataset of phonetically-annotated audiovisual speech. The decision trees allow improved viseme grouping by incorporating k-means clustering into the training algorithm. The use of overlapping dynamic visemes, defined by tri-phone time-varying oral pose boundaries, allows improved modelling of coarticulation effects. We show that our approach leads to a clear improvement over a comparable baseline in perceptual tests. The avatar is based on the freely available MakeHuman and Blender software components.
