This article reviews a book which summarizes and classifies more than 1250 references to experimental work with low-level radiation between 1898 and 1977; explains that the detailed material is presented in tabular form with type of radiation as the primary classification and type of organism and date of report as subclassifications; notes that an incredible variety of effects are specified for flora and fauna; praises the summaries of background radiation and of overall radiation-dose effects to a variety of organisms; and emphasizes the importance of information dealing with the public perception of radiation and its effects.
Resistance-Based Biosensor of Multi-Walled Carbon Nanotubes

Multi-Walled Carbon Nanotubes (MWNTs) are a good choice for resistive biosensors due to their great resistance changes when immunoreactions take place, they are also low-cost, more biocompatible than single-walled carbon nanotubes, and resistive measurement equipment is usually not expensive and readily available. In this work a novel resistive biosensor based on the immobilization of an antigen through a silanization process over the surface of Multi-Walled Carbon Nanotubes (MWNTs) is reported. Results show that the biosensor increases its conductivity when adding the antigen and decreases when adding the antibody making them good candidates for disease diagnosis.
Causes of the rapid warming of the North Atlantic ocean in the mid 1990s

AbstractIn the mid-1990s, the subpolar gyre of the North Atlantic underwent a remarkable rapid warming, with sea surface temperatures increasing by around 1°C in just 2 yr. This rapid warming followed a prolonged positive phase of the North Atlantic Oscillation (NAO) but also coincided with an unusually negative NAO index in the winter of 1995/96. By comparing ocean analyses and carefully designed model experiments, it is shown that this rapid warming can be understood as a delayed response to the prolonged positive phase of the NAO and not simply an instantaneous response to the negative NAO index of 1995/96. Furthermore, it is inferred that the warming was partly caused by a surge and subsequent decline in the meridional overturning circulation and northward heat transport of the Atlantic Ocean. These results provide persuasive evidence of significant oceanic memory on multiannual time scales and are therefore encouraging for the prospects of developing skillful predictions.
Validation of EORTC IN-PATSAT32 for Chinese patients with gastrointestinal cancer

Purpose To test the psychometric properties and applicability of the European Organization for Research and Treatment of Cancer In-patient Satisfaction with Care Questionnaire 32 (EORTC IN-PATSAT32) for Chinese patients with gastrointestinal cancer. Patients and methods A total of 106 inpatients with gastrointestinal cancer at Cangzhou Center Hospital were enrolled in this study. All were treated at Cangzhou Center Hospital from July 2013–March 2014. All participants self-administered the EORTC IN-PATSAT32 and EORTC Quality of Life Questionnaire – Core 30 (EORTC QLQ-C30). Results The Cronbach’s α coefficients were >0.70 for all scales of the EORTC IN-PATSAT32. Multitrait scaling analysis showed that all-item scale correlation coefficients met the standard of convergent validity, while only 50.0% met the standard of discriminant validity. A weak correlation was found between the scales and single items of the EORTC IN-PATSAT32 and EORTC QLQ-C30. Conclusion The EORTC IN-PATSAT32 appears to be a reliable, valid, and acceptable instrument for measuring patient satisfaction among Chinese patients with gastrointestinal cancer.
Exercise Training Prevents the Microvascular Rarefaction in Hypertension Balancing Angiogenic and Apoptotic Factors: Role of MicroRNAs-16, -21, and -126

Aerobic exercise training (ET) lowers hypertension and improves patient outcomes in cardiovascular disease. The mechanisms of these effects are largely unknown. We hypothesized that ET modulates microRNAs (miRNAs) involved in vascularization. miRNA-16 regulates the expression of vascular endothelial growth factor and antiapoptotic protein Bcl-2. miRNA-21 targets Bcl-2. miRNA-126 functions by repressing regulators of the vascular endothelial growth factor pathway. We investigated whether miRNA-16, -21 and -126 are modulated in hypertension and by ET. Twelve-week–old male spontaneously hypertensive rats (SHRs; n=14) and Wistar Kyoto (WKY; n=14) rats were assigned to 4 groups: SHRs, trained SHRs (SHR-T), Wistar Kyoto rats, and trained Wistar Kyoto rats. ET consisted of 10 weeks of swimming. ET reduced blood pressure and heart rate in SHR-Ts. ET repaired the slow-to-fast fiber type transition in soleus muscle and the capillary rarefaction in SHR-Ts. Soleus miRNA-16 and -21 levels increased in SHRs paralleled with a decrease of 48% and 25% in vascular endothelial growth factor and Bcl-2 protein levels, respectively. Hypertension increased Bad and decreased Bcl-x and endothelial NO synthase levels and lowered p-Badser112:Bad ratio. ET in SHR-Ts reduced miRNA-16 and -21 levels and elevated vascular endothelial growth factor and Bcl-2 levels. ET restored soleus endothelial NO synthase levels plus proapoptotic and antiapoptotic mediators in SHR-Ts, indicating that the balance between angiogenic and apoptotic factors may prevent microvascular abnormalities in hypertension. miRNA-126 levels were reduced in SHRs with an increase of 51% in phosphoinositol-3 kinase regulatory subunit 2 expression but normalized in SHR-Ts. Our data show that ET promoted peripheral revascularization in hypertension, which could be associated with regulation of select miRNAs, suggesting a mechanism for its potential therapeutic application in vascular diseases.
Collaborative experience sharing with the support of M-Learning 2.0: a fundamental framework, a case study and research issues

Although conventional mobile learning can help connect students to nature, they are usually taught in the form of 'units', rather than through the use of an entire system. However, students should be taught system-thinking skills in order for them to gain an overall understanding of complex environmental issues. The purpose of this paper is to solve this issue by integrating social media into conventional mobile learning, using a system called M-Learning 2.0. This integration can promote collaborative sharing of life experiences in nature as well as discussion of different perspectives. Therefore, this paper first introduces a fundamental framework that builds an environment according to a social cognition model. Furthermore, a pilot case study involving students collaboratively taking photos via the use of a mobile application is conducted. Finally, further research issues related to M-Learning 2.0 are proposed. It is hoped that this work will provide readers with a potential research blueprint.
A Framework for Structured Linearizations of Matrix Polynomials in Various Bases

We present a framework for the construction of linearizations for scalar and matrix polynomials based on dual bases which, in the case of orthogonal polynomials, can be described by the associated recurrence relations. The framework provides an extension of the classical linearization theory for polynomials expressed in nonmonomial bases and allows us to represent polynomials expressed in product families, that is, as a linear combination of elements of the form $\phi_i(\lambda) \psi_j(\lambda)$, where $\{ \phi_i(\lambda) \}$ and $\{ \psi_j(\lambda) \}$ can either be polynomial bases or polynomial families which satisfy some mild assumptions. We show that this general construction can be used for many different purposes. Among them, we show how to linearize sums of polynomials and rational functions expressed in different bases. As an example, this allows us to look for intersections of functions interpolated on different nodes without converting them to the same basis. We then provide some constructions .
Vitamin D Deficiency and Insufficiency in HIV-infected Children and Young Adults

Background: Vitamin D insufficiency and HIV infection are both risk factors for chronic disorders, so it is important to consider vitamin D status in HIV-infected patients. Methods: We prospectively investigated serum 25-hydroxyvitamin D (25(OH)D) concentrations, determined by radioimmunoassay, in 113 HIV-infected children (age ⩽24 years) and 54 healthy controls matched for age and phototype. We assessed the prevalence of vitamin D deficiency and insufficiency (VDD and VDI) defined as 25(OH)D titers of <10 ng/mL and between 10 and 30 ng/mL, respectively, and their predictive factors. Results: The overall prevalence of VDD and VDI was 38.9% and 58.7%, respectively. Mean serum 25(OH)D concentrations were significantly higher in the HIV group than the control group (14.2 ± 6.9 ng/mL vs. 10.4 ± 5 ng/mL, P < 0.001). Variables significantly associated with low serum 25(OH)D concentrations in HIV-infected children were dark phototype (P < 0.001) and age (r = −0.19, P = 0.03). Patients receiving efavirenz had a trend toward lower serum 25(OH)D concentrations (11.1 ± 4.6 ng/mL vs. 14.6 ± 7 ng/mL, P = 0.1). Dark phototype was the only independent risk factor for VDD in HIV-infected children (odds ratio = 14.6; 95% confidence interval: 2.4–89.9, P = 0.004). Conclusions: VDD and VDI were common in both HIV-infected and control groups, and serum 25(OH)D concentrations were significantly lower in controls than in HIV-infected children.
Single Channel Characterization of the Mitochondrial Ryanodine Receptor in Heart Mitoplasts*

Heart mitochondria utilize multiple Ca2+ transport mechanisms. Among them, the mitochondrial ryanodine receptor provides a fast Ca2+ uptake pathway across the inner membrane to control “excitation and metabolism coupling. ” In the present study, we identified a novel ryanodine-sensitive channel in the native inner membrane of heart mitochondria and characterized its pharmacological and biophysical properties by directly patch clamping mitoplasts. Four distinct channel conductances of ∼100, ∼225, ∼700, and ∼1,000 picosiemens (pS) in symmetrical 150 mm CsCl were observed. The 225 pS cation-selective channel exhibited multiple subconductance states and was blocked by high concentrations of ryanodine and ruthenium red, known inhibitors of ryanodine receptors. Ryanodine exhibited a concentration-dependent modulation of this channel, with low concentrations stabilizing a subconductance state and high concentrations abolishing activity. The 100, 700, and 1,000 pS conductances exhibited different channel characteristics and were not inhibited by ryanodine. Taken together, these findings identified a novel 225 pS channel as the native mitochondrial ryanodine receptor channel activity in heart mitoplasts with biophysical and pharmacological properties that distinguish it from previously identified mitochondrial ion channels.
ENSEMBLE DECISION TREE CLASSIFIER FOR BREAST CANCER DATA

Data mining is the process of analyzing large quantities of data and summarizing it into useful information. In medical diagnoses the role of data mining approaches increasing rapidly. Particularly Classification algorithms are very helpful in classifying the data, which is important in decision making process for medical practitioners. Further to enhance the classifier accuracy various pre-processing techniques and ensemble techniques were developed. In this study a hybrid approach, CART classifier with feature selection and bagging technique has been considered to evaluate the performance in terms of accuracy and time for classification of various breast cancer datasets.
Evaluation of AC loss and temperature distribution in high temperature superconducting tape using COMSOL Multiphysics

High temperature superconductors (HTS) are promising candidates for electrical power applications. The electrical devices using HTS conductors or tapes with high critical temperature (Tc) and high current carrying capability operate with more efficiency and higher power density compared to the conventional one. But the superconductor exhibits energy loss known as AC loss when exposed to time varying external magnetic field and/or transport current. This may lead to increase of temperature inside the superconductor, which may be followed by thermal run away. Therefore the study of AC loss and temperature distribution is important. In this paper, AC loss in an elliptical Ag sheathed Bi2223 (HTS) tape is calculated using the time dependent PDE mode of COMSOL Multiphysics. The HTS tape is subjected to the externally applied time varying magnetic field and transport current. After proper mesh generation in the superconductor and silver subdomains, the time dependent solver is used to get the solution of the primary variable in COMSOL Multiphysics. The effect of amplitude of applied AC fields and transport currents are observed using the post-processing unit of COMSOL Multiphysics. Using the calculated AC losses as the heat sources in physics settings, the temperature distribution inside the superconducting tape is evaluated. This is done with the help of the heat transfer module of COMSOL Multiphysics. Proper thermal boundary conditions and anisotropic thermal conductivity of the HTS tape are applied in boundary and sub-domain settings respectively. Lastly, the temperature rise at a certain spot inside the Bi2223/Ag tape is investigated to observe the evolution of temperature rise.
Exploring Audience Behaviour During Contemporary Dance Performances

How can performers detect and potentially respond to the reactions of a live audience? Audience members' physical movements provide one possible source of information about their engagement with a performance. Using a case study of the dance performance "Frames" that took place in Theatre Royal in Glasgow during March 2015, we examine patterns of audience movement during contemporary dance performances and explore how they relate to the dancer's movements. Video recordings of performers and audience were analysed using computer vision and data analysis techniques extracting facial expression, hand gestural and body movement data. We found that during the performance audiences move very little and have predominantly expressionless faces while hand gestures seem to play a significant role in the way audiences respond. This suggests that stillness i.e. the absence of motion may be an indicator of engagement.
VERY LOW MASS STELLAR AND SUBSTELLAR COMPANIONS TO SOLAR-LIKE STARS FROM MARVELS. I. A LOW-MASS RATIO STELLAR COMPANION TO TYC 4110-01037-1 IN A 79 DAY ORBIT

TYC 4110-01037-1 has a low-mass stellar companion, whose small mass ratio and short orbital period are atypical among binary systems with solar-like (Teff ≲ 6000 K) primary stars. Our analysis of TYC 4110-01037-1 reveals it to be a moderately aged (≲5 Gyr) solar-like star having a mass of 1.07 ± 0.08 M☉ and radius of 0.99 ± 0.18 R☉. We analyze 32 radial velocity (RV) measurements from the SDSS-III MARVELS survey as well as 6 supporting RV measurements from the SARG spectrograph on the 3.6 m Telescopio Nazionale Galileo telescope obtained over a period of ∼2 years. The best Keplerian orbital fit parameters were found to have a period of 78.994 ± 0.012 days, an eccentricity of 0.1095 ± 0.0023, and a semi-amplitude of 4199 ± 11 m s−1. We determine the minimum companion mass (if sin i = 1) to be 97.7 ± 5.8 MJup. The system's companion to host star mass ratio, ⩾0.087 ± 0.003, places it at the lowest end of observed values for short period stellar companions to solar-like (Teff ≲ 6000 K) stars. One possible way to create such a system would be if a triple-component stellar multiple broke up into a short period, low q binary during the cluster dispersal phase of its lifetime. A candidate tertiary body has been identified in the system via single-epoch, high contrast imagery. If this object is confirmed to be comoving, we estimate it would be a dM4 star. We present these results in the context of our larger-scale effort to constrain the statistics of low-mass stellar and brown dwarf companions to FGK-type stars via the MARVELS survey.
Aboveground Biomass and Carbon Stocks of an Undisturbed Regenerating Sal (Shorea Robusta Gaertn. F.) Forest Of Goalpara District, Assam, Northeast India

The present paper deals with the above ground biomass and carbon stocks of an undisturbed Sal forest of Goalpara district, Assam, Northeast India. The average AGB and C were recorded 239.45 ± 12.8 Mg ha -1 and 119.73 ± 6.4 Mg ha -1 . Density distribution curve indicates the high carbon sequestration potential of the stand in near future which further helps in climate change mitigation. Currently, conservation measures are well imposed in combine effort of local community and government. Legal involvement of local community in conservation exercises along with the forest department might be very effective in management of Sal forests.

Partially-coherent distributed space-time codes with differential encoder and decoder

Distributed space-time coding is a mean of achieving diversity through cooperative communication in a wireless relay network. In this paper, we consider a transmission protocol that follows a two-stage model: transmission from source to relays in the first stage, followed by a simple relaying technique from relays to destination. The relays transmit a vector which is a transformation of the received vector by a relay-specific unitary transformation. We assume that the relays do not have any channel information, while the destination has only a partial-channel knowledge, by which we mean that destination knows only the relay-to-destination channel. For such a setup, we derive a Chernoff bound on the pairwise error probability and propose code design criteria. A second contribution is the differential encoding and decoding scheme for this setup, which is different from the existing ones. Furthermore, differential codes from cyclic division algebra are proposed that achieve full diversity. For our setup with two relays, a Generalized PSK code is shown to achieve full diversity, for which the decoding complexity is independent of code size

On the Size and Spacing of Volcanogenic Massive Sulfide Deposits within a District with Application to the Matagami District, Quebec

Volcanogenic massive sulfide (VMS) districts are typically ~40 km in diameter and contain about a dozen regularly spaced Zn-Cu orebodies, one or two of which contain more than half of the district’s resources. We numerically investigate this deposit size and spatial distribution by calculating zinc transport across the sea floor, first above sills of simple geometry, and then above the Bell River Complex at Matagami. For sills with simple rectangular geometry (i.e., a constant thickness), convection is strongest at the edge. The edge convection induces a progression of convection cells above the sill, although the sill cools mainly by the retreat of its thermal edges toward the sill center. If the rock permeability is a function of temperature that is maximized at 375°C, the resulting vents occur at stable, discrete locations that proxy for ore deposits. The fraction of sill heat vented at or above 300°C and the potential metal resources of the districts are greatest if the host permeability is 10−15 m2 (1 millidarcy) and the sill top is at 1 km depth. The simulations suggest that, as the host permeability increases, a single large deposit will progressively dominate a host of smaller ones. The Matagami simulations are based on a sill that tapers from 6.5 to 0 km thickness over a distance of 30 km. In the model, convection occurs both above the sill and along its underside, and metal is extracted from both sides of the cooling sill. The spacing of the resulting discharge sites is similar to that observed in actual VMS districts and, where direct comparison is possible, the mass of metal deposited is similar for an accumulation efficiency of ~3 percent.
Comments on the genesis of De Geer moraines

These comments are based on an outline study of the last deglaciation in Finnmark (Sollid et al. 1973) and later detailed mapping of Pasvik (Carlson et al. 1984), including special studies of De Geer moraines (Sollid & Carlson 1984) (Fig. 1).
Thrust-front zone of the Precordillera, Argentina; a thick-skinned triangle zone

The frontal thrust zone of the Precordillera thrust belt of western Argentina only superficially resembles a classical Alberta-style triangle zone. In this thick-skinned triangle zone, the thrust front is the result of interaction between the eastward-verging, thin-skinned Central Precordillera and the westward-verging, thick-skinned Eastern Precordillera system. The western boundary, formed by the Niquivil thrust plate, has been refolded and faulted by thrust faults from the Eastern Precordillera at several localities. The deformation is still active. We divide the thick-skinned triangle zone into three segments based on the system's activity: independent, late interfering, and collision zones. Balanced cross sections across a thick-skinned triangle zone show a uniform s ortening for the Eastern Precordillera (~17 km). The structural geometry suggests multiple reactivation of the main faults. The thick-skinned triangle zone began to grow after 2.6 Ma and is still active. Episodic and alternating opposing movement is controlled by buttressing of the thin-skinned thrust system against the basement structures of the Eastern Precordillera.
Maternal employment and parent-child relationships in single-parent families of low-birth-weight preschoolers.

BACKGROUND The influence of premature birth of an infant in female-headed, single-parent families together or in conjunction with family environment factors, such as employment of the mother, on the mother-premature child relationship has not been considered in past studies. OBJECTIVES To explore differences in parent-child and family relationships for employed and nonemployed single mothers of low-birth-weight (LBW) and full-term preschool children and to describe the relationships of the mother's employment status, employment history, and employment attitude-behavior consistency to parent-child and family relationships. METHODS Single mothers with LBW (n = 60) and full-term (n = 61) preschool children provided data on their employment situation, the Parenting Stress Index, the Feetham Family Functioning Survey, and the Home Observation for Measurement of the Environment. RESULTS Employed mothers had more positive perceptions and provided more enriching home environments for their children. Greater attitude-behavior consistency was associated with more positive perceptions of the parental role. CONCLUSION Thus, in single-parent families, employment and consistency are positive influences on the mother-child relationship.
