Solubility of platinum in aqueous solutions at 25°C and pHs 4 to 10 under oxidizing conditions

Platinum has been found to be mobile under supergene conditions, including placers and weathering profiles. To elucidate the nature of Pt mobility in supergene environments, the dissolution of platinum metal was investigated under physicochemical conditions similar to those found in such environments. The solubility of platinum metal was measured at 25°C in several systems: Pt-K-HC8H4O4-H2O (pH 4.02), Pt-Na-HCO3-Cl-H2O (pH 6.40), Pt-Na-KH2PO4-HPO4-H2O (pH 6.90), Pt-Na-HCO3-H2O (pH 8.30), Pt-Na-OH-H2O (pH 8.54), and PtNa-HCO3-H2O (pH 9.91). The redox conditions of these experiments were relatively oxidizing, with measured Eh values ranging from +280 to +590 mV. The ionic strength of the aqueous solutions did not exceed 0.30 (molal scale). The interpretation of the solubility results, in terms of the following reaction and its equilibrium constant, Pt(s)+nH2O Pt(OH)2−n+nH+2e served to identify the importance of the hydroxylated complex PtOH in the pH range (4 to 10) and to determine its stability constant at 25°C. Linear regression of the solubility data using the function log [Pt]−2pe=n pH+log Kn yielded a value of 1.01 ± 0.07 for n, the average ligand number, and −31.76 ± 0.55 for the thermodynamic equilibrium constant of reaction. The resulting stability constant (β1) of PtOH (Pt + OH PtOH) is 24.91 ± 0.50, assuming the same value of the free energy of formation of Pt, ΔGf(Pt) as that given by Glushko et al. (Thermodynamic Constants of Matter, Academy of Science, USSR, 1972). The range of values of ΔGf(Pt) proposed to date is +185.63 to +258.74 kJ/mol. The value of Glushko et al. (1972) (+244.11 kJ/mol) appears to fit better with our measurements at pH 4 to 10 and with those of Wood (Wood S. A., “Experimental determination of the hydrolysis constants of Pt and Pd at 25°C from the solubility of Pt and Pd in aqueous hydroxide solutions,” Geochim. Cosmochim. Acta 55, 1759–1767, 1991) at pH 9 to 15.5. Finally, according to these new measurements of the solubility of platinum, the recommended values for Gibbs free energy (ΔGf, in kiloJoule per mole) of the different aqueous species of Pt are +244.11 (Pt), −55.96 (PtOH), and −234.48 (Pt(OH)2(aq)). The integration of data from the literature for chloride and sulfate complexes was used to calculate the speciation of platinum in seawater and in solutions with variable chlorinity (0.1, 1, and 3 mol/L NaCl) at 25°C. These calculations showed that in the absence of strong ligands (i.e., S2O3, CN), the transport of platinum in supergene environments primarily occurs in the form of PtOH (90%) and Pt(OH)2(aq) (9.7%). Chloride complexes (PtCl4 and PtCl3) account for less than 1% of the dissolved platinum. This study clearly shows that the hydroxylated complexes (PtOH and Pt(OH)2(aq)) can play a very important role in controlling platinum transfer mechanisms in surface fluids (soils, placers, weathering profiles, etc.). Because the charged species PtOH is largely predominant, the mobility and transfer of platinum can also be affected by adsorption-desorption mechanisms onto oxides and hydroxides.
Motions and functional performance after supervised physical therapy program versus home-based program after arthroscopic anterior shoulder stabilization: a randomized clinical trial.

OBJECTIVE
To compare the effects of a standardized supervised physical therapy versus a controlled home-based programs on the rate of shoulder motion and functional recovery after arthroscopic anterior shoulder stabilization.


METHODS
Twenty-seven patients (18-35years) underwent arthroscopic anterior shoulder stabilization. Patients were randomized into two groups. A supervised group (n=14) received a rehabilitation program, 3 sessions/week for 24 weeks and a controlled home treated group (n=13) who followed a home-based program for same period. Range of motion (ROM) of the shoulder was assessed 4 times after each phase of rehabilitation and function was assessed after the 3rd and 4th phase of rehabilitation.


RESULTS
Both groups achieved a significant progressive increase in all shoulder motions throughout the study period. Patients in the supervised group achieved 92.6% and 94.2% of the contralateral side in abduction and forward elevation respectively. The controlled home-based group achieved 87.1% and 94.7% of abduction and forward elevation respectively. For external rotation, the percentage ROM achieved was 81.1% for the supervised group and 76.4% for the controlled home-based group. For function assessment, the two groups showed a significant improvement. However, the two groups were not significantly different from each other in all measured variables.


CONCLUSION
A controlled home-based physical therapy program is as effective as a supervised program in increasing shoulder range of motion and function after arthroscopic anterior shoulder stabilization.
Effects of climate change on maize production, and potential adaptation measures: a case study in Jilin Province, China

Jilin is among the most important grain-producing provinces in China. Its maize production plays an important role in local and national food security. In this study, we developed a new approach to assess the vulnerability and adaptation options for Jilin maize yields with respect to climate change by modifying a site-based biophysical model to a spatial grid-based application. An ensemble approach that used a combination of 20 general circulation model results and 6 scenarios from the Special Report on Emissions Scenarios was adopted in order to reflect the high uncertainties in future climate projections. The results show that the yield is highly likely to decline in the western and central regions of Jilin but to increase in the east, where maize is not currently grown as the main crop. Phenologically, the growing season will be reduced in the central and western parts, leading to a shortened grain-filling period. The average maize yield in the west and central regions is thus projected to decrease 15% or more by 2050 as predicted by 90% of 120 projected scenarios. In addition, CO2 fertilization was investigated and demonstrated a noticeable compensation effect on the yield deduction. However, further field work and/or laboratory-based experiments are required to validate the modeled CO2 fertilization effects. Two potential adaptation strategies, i.e. improving irrigation facilities and introducing cultivars, were identified from the vulnerability assessment and were further tested for the reduction areas. The results revealed that the increase in effective irrigation by upgrading the irrigation system would help to maintain the current production level, but in the long run, the maize cultivars need to be introduced in line with the future warming climate.

CPW-fed wideband printed planar dipole antenna for Digital TV

In recent years, Digital TV (DTV) terrestrial broadcasting has been widely spread in the world. Additionally, it is expected to smoothly replace all the conventional analog TV broadcasting. However, in order to meet good receiving performance, a DTV antenna with an ultra-wide band and a high gain is generally investigated. In the literature associated with Co-Planar Waveguide (CPW)-fed wideband printed antennas [1], [2], the printed monopole antenna with a step-sloped ground plane was developed to extend the bandwidth and the printed monopole antenna was successfully implemented for WLAN/WIMAX applications. In this work, we use the CPW-fed mechanism on the dipole antenna in which multiple loops are constructed. Since each loop corresponds to a specific frequency response, multiple loops can yield the integrated frequency response. Restated, all frequency responses of multiple loops are coupled to reach an ultra-wide band. Hence, the proposed CPW-fed wideband printed planar dipole antenna can have a large bandwidth for DTV applications.
The Probability of Backtest Overfitting

Most firms and portfolio managers rely on backtests (or historical simulations of performance) to select investment strategies and allocate them capital. Standard statistical techniques designed to prevent regression overfitting, such as hold-out, tend to be unreliable and inaccurate in the context of investment backtests. We develop a framework that estimates the probability of backtest overfitting (PBO) specifically in the context of investment simulations, through a nonparametric numerical method that we call combinatorially symmetric cross-validation (CSCV). We show that CSCV produces accurate estimates of the probability that a particular backtest is overfit.
Associations between emotional intelligence, depression and suicide risk in nursing students.

BACKGROUND
The most important factor which predisposes young people to suicide is depression, although protective factors such as self-esteem, emotional adaptation and social support may reduce the probability of suicidal ideation and suicide attempts. Several studies have indicated an elevated risk of suicide for health-related professions. Little is known, however, about the relationship between perceived emotional intelligence and suicide risk among nursing students.


OBJECTIVES
The main goals were to determine the prevalence of suicide risk in a sample of nursing students, to examine the relationship between suicide risk and perceived emotional intelligence, depression, trait anxiety and self-esteem, and to identify any gender differences in relation to these variables.


METHOD
Cross-sectional study of nursing students (n=93) who completed self-report measures of perceived emotional intelligence (Trait Meta-Mood Scale, which evaluates three dimensions: emotional attention, clarity and repair), suicide risk (Plutchik Suicide Risk Scale), self-esteem (Rosenberg Self-esteem Scale), depression (Zung Self-Rating Depression Scale) and anxiety (Trait scale of the State-Trait Anxiety Inventory).


RESULTS
Linear regression analysis confirmed that depression and emotional attention are significant predictors of suicidal ideation. Moreover, suicide risk showed a significant negative association with self-esteem and with emotional clarity and repair. Gender differences were only observed in relation to depression, on which women scored significantly higher. Overall, 14% of the students were considered to present a substantial suicide risk.


CONCLUSIONS
The findings suggest that interventions to prevent suicidal ideation among nursing students should include strategies to detect mood disorders (especially depression) and to improve emotional coping skills. In line with previous research the results indicate that high scores on emotional attention are linked to heightened emotional susceptibility and an increased risk of suicide. The identification and prevention of factors associated with suicidal behaviour in nursing students should be regarded as a priority.
Influenza A viruses dual and multiple infections with other respiratory viruses and risk of hospitalisation and mortality

INTRODUCTION
Recent literature suggests that dual or multiple virus infections may affect disease severity. However, few studies have investigated the effect of co-infection with influenza A viruses.


OBJECTIVES
To identify the association between influenza A and respiratory viruses co-infections with disease outcome.


METHODOLOGY
Data for samples from North West England tested between January 2007 and June 2011 was analysed for patterns of co-infection between influenza A viruses and eight respiratory viruses. Risk of hospitalisation to ICU or general ward in single versus co-infections was assessed using logistic regression.


RESULTS
Of the 25,596 samples analysed for respiratory viruses 40·7% (10,501) were positive for any virus. Co-infections were detected in 4·7% (137/2879) of all patients with influenza A(H1N1)pdm09, and 7·3% (57/779) of those with other influenza A virus infections. Co-infection between seasonal influenza A viruses and influenza B virus was associated with a significant increase in the risk of admission to ICU/death (OR: 22·0, 95% CI: 2·21-219·8, P=0·008). Respiratory syncytial virus/influenza A (RSV/Flu A) co-infection also increased this risk but was not statistically significant. For influenza A(H1N1)pdm09, RSV and AdV co-infection increased risk of hospitalisation to general ward whereas Flu B increased risk of admission to ICU, but none of these were statistically significant.


CONCLUSION
Co-infection is a significant predictor of disease outcome; combined treatment, introduction of an integrated vaccine for all respiratory viruses and development of multi-target rapid diagnostic tests is recommended. Integration of respiratory viruses' co-infections into public health reports could also contribute to the accumulation of evidence.

The Perceived Advantage of Agile Development Methodologies By Software Professionals: Testing an Innovation-Theoretic Model

Proponents of agile processes claim that agile practices result in higher quality software while allowing the flexibility to respond to evolving user requirements. Yet, to the best of our knowledge, no empirical study has really confirmed that benefits accrue to those who use agile processes. Grounded in the agility and diffusion of innovations literature, this research introduces a measure of process agility within the software development domain and relates it to constructs previously employed in the innovation literature. For agile methods, our study has provided empirical support for the proposal that agile development methods lead to developers’ beliefs that they are less complex, more compatible and provide increased benefits. Since developers believe that agility leads to increased benefits, they will be more likely to accept agile methods. For practitioners, this study provides valuable insights into the underlying factors that influence a developer’s beliefs about agile methods.

Supersymmetric Theory of (Color)superconductivity

A few years ago, I published papers on the examinations of the theory of BCS superconductivity in systems (metal, metalic hydrogen, plasma, neutron star, etc.) they have various numerical values of chemical potential µ [1,2,3]. It was shown that the BCS behavior is quite universal under the variation of chemical potential. In this talk, I discuss the extension of these previous publications to the case where the effect of SUSY, namely superpartner, might appear clearly. We consider (color)superconductivity ((C)SC) of a condensed matter with µ ∼ O(∆), where ∆ is the SUSY breaking scale (∼ TeV). Recently, attempts to examine the theories of CSC from the viewpoint of SUSY appeared in literature [4,5]. According as the results of the nonperturbative method of SUSY gauge theories, Ref. [4] discussed the symmetry breaking patterns of the N = 1 SQCD at µ = 0, and ∆ = 0 for squarks. Because the validity of the exact results of SUSY gauge theories to the problem of CSC is not clear, the method of Ref. [4] could apply to the situation of µ < ∆ ≪ Λ SQCD , where µ and ∆ could be regarded as a small perturbation to a SUSY gauge theory. The purpose and/or situation of this work are different from that of Refs. [4,5]. The summary of the method of this work: (1) The case of both U (1) and SU (N c) gauge symmetries are examined. (2) Both the N = 1 4D and N = 2 3D cases are considered. (3) To construct a BCS-type theory, we employ the N = 1 4D generalized SUSY Nambu−Jona-Lasinio model with µ = 0 as the model Lagrangian. (4) The N = 2 3D theory is obtained by a dimensional reduction of the 4D counterpart. (5) After adopting SUSY auxiliary fields for diquark-type composites, the effective potential and the gap equation are obtained by the method of large-N expansion. The summary of the results: (1) By examining the quasiparticle excitation energy spectra and the gap equations, the conditions for Bose-Einstein condensation of the scalar sector, dynamical chiral symmetry breaking (DCSB), and (color)superconductivity were found. (2) The effects of the bosonic part in the gap equation in the SUSY BCS theory have been reviewed, while there is no SUSY effect in the thermodynamic character of the SUSY (C)SC. (3) The (C)SC shows the BCS character even if µ is close to …

DRAMsim: a memory system simulator

As memory accesses become slower with respect to the processor and consume more power with increasing memory size, the focus of memory performance and power consumption has become increasingly important. With the trend to develop multi-threaded, multi-core processors, the demands on the memory system will continue to scale. However, determining the optimal memory system configuration is non-trivial. The memory system performance is sensitive to a large number of parameters. Each of these parameters take on a number of values and interact in fashions that make overall trends difficult to discern. A comparison of the memory system architectures becomes even harder when we add the dimensions of power consumption and manufacturing cost. Unfortunately, there is a lack of tools in the public-domain that support such studies. Therefore, we introduce DRAMsim, a detailed and highly-configurable C-based memory system simulator to fill this gap. DRAMsim implements detailed timing models for a variety of existing memories, including SDRAM, DDR, DDR2, DRDRAM and FB-DIMM, with the capability to easily vary their parameters. It also models the power consumption of SDRAM and its derivatives. It can be used as a standalone simulator or as part of a more comprehensive system-level model. We have successfully integrated DRAMsim into a variety of simulators including MASE [15], Sim-alpha [14], BOCHS[2] and GEMS[13]. The simulator can be downloaded from www.ece.umd.edu/dramsim.
Duodenal stenting for malignant gastric outlet obstruction: prospective study.

AIM
To evaluate the results of duodenal stenting for palliation of gastroduodenal malignant obstruction by using a gastric outlet obstruction score (GOOS).


METHODS
A prospective, non-randomized study was performed at a tertiary center between August 2005 and April 2010. Patients were eligible if they had malignant gastric outlet obstruction (GOO) and were not candidates for surgical treatment. Medical history and patient demographics were collected at baseline. Scheduled interviews were made on the day of the procedure and 15, 30, 90 and 180 d later or unscheduled as necessary.


RESULTS
Fifteen patients (6 male, 9 female; median age 61 years) with GOO who had undergone duodenal stenting were evaluated. Ten patients had metastasis at baseline (66.6%) and 14 were unable to accept oral intake (93.33%), including 7 patients who were using a feeding tube. Laboratory data showed biliary obstruction in eight cases (53.33%); all were submitted to biliary drainage. Two patients developed obstructive symptoms due to tumor ingrowth after 30 d and another due to tumor overgrowth after 180 d. Two cases of stent migration occurred. A good response to treatment was observed, with a mean time of approximately 1 d (19 h) until toleration of a liquid diet and slightly more than 2 d for both soft solids (51 h) and a solid food/normal diet (55 h). The mean time to first failure to maintain liquid intake (GOOS ≥ 1) was 93 d. During follow-up, the mean time to first failure to maintain the previously achieved GOOS of 2-3 (solid/semi-solid food), considered technical failure, was 71 d. On the basis of oral intake a GOOS is defined: 0 for no oral intake; 1 for liquids only; 2 for soft solids only; 3 for low-residue or full diet.


CONCLUSION
Enteral stenting to alleviate gastroduodenal malignant obstruction improves quality of life in patients with limited life expectancy, which can be evaluated by using a GOO scoring system.
A Computer Vision System for Lateral Localization

For urban driving, knowledge of ego-vehicle’s position is a critical piece of information that enables advanced driver-assistance systems or self-driving cars to execute safety-related, autonomous driving maneuvers. This is because, without knowing the current location, it is very hard to autonomously execute any driving maneuvers for the future. The existing solutions for localization rely on a combination of a Global Navigation Satellite System, an inertial measurement unit, and a digital map. However, in urban driving environments, due to poor satellite geometry and disruption of radio signal reception, their longitudinal and lateral errors are too significant to be used for an autonomous system. To enhance the existing system’s localization capability, this work presents an effort to develop a vision-based lateral localization algorithm. The algorithm aims at reliably counting, with or without observations of lane-markings, the number of road-lanes and identifying the index of the road-lane on the roadway upon which our vehicle happens to be driving. Tests of the proposed algorithms against intercity and interstate highway videos showed promising results in terms of counting the number of road-lanes and the indices of the current road-lanes.
