Glacier runoff shows significant change under global warming in the headwater region of the Indus River with great impact on its highly populated downstream area, but the hydrochemistry characteristics of meltwater and the changing mechanism remain unclear in this region. In this study, runoff water samples were collected during May and June, 2015, from four glacial catchments in the Upper Indus Basin to investigate general characteristics and daytime dynamics of meltwater runoff together with sediment and chemical contents. Results showed that glacier runoff in the studied area had an alkaline pH and much higher sediment yields than the local average of the non-glacier areas. The carbonate-dominated geological feature in the four catchments resulted in single chemical facies of Ca-HCO3. The dominant process determining the glacier runoff chemistry was rock-water interaction, with less soluble minerals and less intensive evaporate weathering in the Passu and Gulmit catchments than the B&B and Hinarchi catchments. Comparing the investigated catchments, the larger glacier with longer flow path exhibited higher runoff but lower melting rate, higher SSC resulting from higher erosive power of flow, and higher solute concentrations as a consequence of more intensive contact of meltwater with rock minerals along the longer flow path. For individual catchments, a negative correlation between TDS and flow rate (R2 = 0.26~0.53) and changing trends of ion ratios with flow rate demonstrated that under intensive melting conditions, rock-water interactions were reduced, resulting in dilution of solutes. Overall, the general chemical characteristics of the investigated glacier runoff indicated geological control, whereas individual glacier illustrated hydrological control on the daytime dynamics of glacier runoff chemistry. The presence of glacier terminal lake and agriculture land can significantly alter the hydrochemistry of downstream runoff.

For authentication purposes, the identification and verification of a user is done by biometric traits like finger print, face, iris and gait, etc. Among the various traits finger print is mostly used in commercial applications for recognizing user's identity. The other hand based modalities such as vein, and finger knuckle are gaining importance. This paper proposes a methodology for secure biometrics authentication using Finger Knuckle Print (FKP). The texture patterns from finger knuckle are extracted using Gabor with Exception-Maximization (EM) algorithm and the feature vectors from these texture patterns are acquired using Scale Invariant Feature Transform (SIFT) algorithm. The main focus is to reduce the false rejection rate without increasing the false acceptance rate and to improve the performance over the conventional hand based modalities. The performance is compared with Genuine Acceptance Rate (GAR) and False Rejection Rate (FRR). One of the advantages of FKP authentication is its user friendliness in data collection.

With increasing global migration, health care providers and patients may lack a shared language. Interpreters help to secure understanding. Doctors and patients cannot evaluate how the interpreter translates their utterances; however, they can see hand movements, which can provide a window into the interpretation process. While research on natural language use has acknowledged the semiotic contribution of co-speech gestures (i.e., spontaneous hand and arm movements that are tightly synchronized with speech), their role in interpreted interactions is unstudied. We aimed to reveal whether gestures could shed light on the interpreting process and to develop a systematic methodology for investigating gesture-use in interpreted encounters. Using data from authentic, interpreted clinical interactions, we identified and analyzed gestures referring to the body (i.e., body-oriented gestures). Data were 76 min of video-recorded doctor-patient consultations at two UK inner-city general practices in 2009. Using microanalysis of face-to-face dialogue, we revealed how participants used body-oriented gestures and how interpreters transmitted them. Participants used 264 body-oriented gestures (doctors = 113, patients = 54, interpreters = 97). Gestures served an important semiotic function: On average, 70% of the doctors' and patients' gestures provided information not conveyed in speech. When interpreters repeated the primary participants' body-oriented gestures, they were highly likely to accompany the gesture with speech that retained the overall utterance meaning. Conversely, when interpreters did not repeat the gesture, their speech tended to lack that information as well. A qualitative investigation into the local effect of gesture transmission suggested a means for quality control: visible discrepancies in interpretation generated opportunities to check understanding. The findings suggest that clinical communication training could benefit from including skills to understand and attend to gestures. The analysis developed here provides a promising schema and method for future research informing clinical guidelines and training.

Gentle encouragement to approach appears to reduce risk for anxiety and is commonly incorporated into parenting interventions for inhibited preschoolers, yet little is known regarding whether gentle encouragement facilitates in-the-moment regulation as shy or inhibited children face social novelty, particularly during the toddler period. The current study used a sample of 55 temperamentally shy toddlers (21-24 months old) to examine toddler regulation in novel social contexts in relation to parental gentle encouragement to engage. Contexts included low-threat social novelty (i.e., a clown and puppets) and moderately threatening social novelty (i.e., strangers). Using an experimental design, parents were randomly assigned to provide behaviors thought to represent gentle encouragement: warm responsiveness to toddler fear and encouragement of toddler autonomy, prompt to engage, both warmth and prompt, or remaining uninvolved (no-encouragement control). Relative to toddlers in the no-encouragement control condition, toddlers whose parents were instructed to provide warmth showed less fear and more engagement in moderately threatening social contexts, and toddlers whose parents were instructed to provide both warmth and prompts showed greater suppression of respiratory sinus arrhythmia in low-threat social contexts. Findings suggest that parental gentle encouragement may promote regulated responses in social contexts in shy toddlers. Encouragement of toddler autonomy and warm responsiveness to toddlers in particular may help shy toddlers to engage with, rather than withdraw from, new people.

Evaluations of ozone effects on vegetation across the globe over the last seven decades have mostly incorporated exposure levels that were multi-fold the preindustrial concentrations. As such, global risk assessments and derivation of critical levels for protecting plants and food supplies were based on extrapolation from high to low exposure levels. These were developed in an era when it was thought that stress biology is framed around a linear dose-response. However, it has recently emerged that stress biology commonly displays non-linear, hormetic processes. The current biological understanding highlights that the strategy of extrapolating from high to low exposure levels may lead to biased estimates. Here, we analyzed a diverse sample of published empirical data of approximately 500 stimulatory, hormetic-like dose-responses induced by ozone in plants. The median value of the maximum stimulatory responses induced by elevated ozone was 124%, and commonly <150%, of the background response (control), independently of species and response variable. The maximum stimulatory response to ozone was similar among types of response variables and major plant species. It was also similar among clades, between herbaceous and woody plants, between deciduous and evergreen trees, and between annual and perennial herbaceous plants. There were modest differences in the stimulatory response between genera and between families which may reflect different experimental designs and conditions among studies. The responses varied significantly upon type of exposure system, with open-top chambers (OTCs) underestimating the maximum stimulatory response compared to free-air ozone-concentration enrichment (FACE) systems. These findings suggest that plants show a generalized hormetic stimulation by ozone which is constrained within certain limits of biological plasticity, being highly generalizable, evolutionarily based, and maintained over ecological scales. They further highlight that non-linear responses should be taken into account when assessing the ozone effects on plants.

The rapid growth of Internet of Things has provided a new aspect to air quality monitoring system. In Taiwan, over 5000 PM2.5 sensors have been installed in the last two years. The greatest asset of low-cost sensors is possibly mapping spatiotemporal air pollution with finer resolution. But the data quality of low-cost sensors is the most common question that how to take proper interpretation of the measurements. This study proposes an efficient calibration approach based on generalized additive model which is further applied to a particular low-cost PM2.5 sensor in Taiwan. The study carried out a field calibration that collecting both measurements of low-cost sensors and the regulatory stations, and investigated the space/time bias between the low-cost sensors and regulatory stations. Results show that the proposed approach can explain the variability of the biases from the low-cost sensors with R-square of 0.76. In addition, the present calibration model can quantify the uncertainty of the low-cost sensors observations and the average standard deviation is about 13.85% with respect to its adjusted levels. This operational spatiotemporal data calibration approach provides an useful information for local communities and governmental agency to face the new era of IoT sensor for air quality monitoring.
