Authors: Anjum Noshin , Hossain Md. Motaleb 
Published: July 2024

Estimating the discharge from a rainfall event is a challenging task because of a number of affecting elements. A multitude of physiographic factors are essential for both channel and surface flow. In a developing nation like Bangladesh, discharge measurement is critical for forecasting floods, managing land, measuring sediment, nutrients and promoting sustainable development. It is possible to measure the discharge and physiographic parameter using a hydrological model. Using a semi-distributed model Soil and water Assessment Tool (SWAT), the discharge of the Teesta River Basin, one of the most significant basins of Bangladesh, is simulated for the years 2003 to 2020. Sequential Uncertainty Fitting version2 (SUFI-2) technique within SWAT-CUP (SWAT Calibration Uncertainty Program) is used to accomplish model calibration and validation for daily time periods utilizing physiographic parameters. The simulation period of this study spans from 2003 to 2020, and the meteorological data utilized includes temperature, wind speed, relative humidity and rainfall. With and , our calibration results for the time period 2003–2011 demonstrated a strong correlation between observed and simulated discharge. Reasonable values are obtained for the and , which are 0.65 and 0.70 for the validation period 2012-2020. Sensitivity analysis is an integral part of model development and involves analytical examination of input parameters to aid in model validation and provide guidance for future research and sustainable development. Sensitivities of physiographic parameters have been analyzed using SUFI-2 algorithm in SWAT-CUP. It is done by global and one-at-a-time sensitivity procedures. For the Teesta river basin parameters coefficient curve number CN2.mgt, saturated hydraulic conductivity of the soil lair SOL_K ().sol and soil bulk density SOL_BD ().sol show most sensitivity for both of global and one-at-a-time sensitivity procedures. The findings contribute to predict the discharge in period of no observe data as well as to enhance the understanding and informing decision-making processes for sustainable water resource management.
Oxygen isotope signatures preserved in tree ring cellulose as a proxy for April–September precipitation in Fujian, the subtropical region of southeast China

Published: November 2013

AbstractA tree ring cellulose oxygen isotope (δ18O) chronology for the period 1870–2011 was established using samples from four Fokienia hodginsii trees with the aim of exploring the potential to use tree ring δ18O records to reconstruct climatic variations in Fujian, a subtropical region of southeast China. We believe that this is the first tree ring δ18O chronology from this area. Response analysis revealed that tree ring δ18O is significantly correlated with precipitation between April and September, relative humidity between August and October, and the Palmer drought severity index between April and October. Our δ18O chronology accounts for 37.4% (24.6%) of actual variation in precipitation between April and September during the period from 1951 to 2011 (1901 to 2011). Spatial correlation analysis revealed that tree ring cellulose δ18O is a suitable proxy for reconstructing April–September precipitation in Fujian, as well as in parts of Guangdong and Jiangxi, southeast China. In addition, significant correlations between δ18O chronology and the Indian summer monsoon index show that large‐scale atmosphere circulation also influences tree ring δ18O. Comparisons between the tropical Pacific sea surface temperature (SST) and tree ring δ18O, during the period from 1895 to 2009, indicate that the tropical Pacific SST is positively correlated with tree ring δ18O in the study region over the last 110 years, except between 1920 and 1960. Reduced El Niño–Southern Oscillation (ENSO) variance from 1920 to 1960 may result in collapsed relationship between tree ring δ18O in Fujian and tropical Pacific SST.
Change of the wintertime SSTA variability over the West Pacific after the mid‐1980s: Effect of the increasing El Niño Modoki
Authors: Yang Chengyun , Ren Baohua , Li Gen , Zheng Jianqiu 
Published: November 2013

AbstractFrom 1949 to 2010, the EOF 1 of sea surface temperature anomalies (SSTA) over the West Pacific (WP) in the boreal winter shows a clear increase during the 1980s, which is associated with the increase in global SSTA. It is found that the characteristics of WP SSTA are different since the mid‐1980s. Before the mid‐1980s, the first EOF presents a dipole pattern associated with El Niño. After the mid‐1980s, EOF1 of WP SSTA captures a uniform SSTA variability over WP and is related to El Niño Modoki. Meanwhile, the dipole SSTA pattern captured by EOF2 is associated with the canonical El Niño. The generation of these two different SSTA patterns might be attributed to the different atmospheric responses to El Niño and El Niño Modoki. The impact of El Niño Modoki over the WP SSTA is significantly enhanced along with the increased occurrences of El Niño Modoki. The increasing intensity of WP SSTA variability has a similar period with that of El Niño Modoki. During El Niño Modoki, the central Pacific SSTA has a leading impact on the development of the WP SSTA by a Rossby wave response. July(0) to October(0) is suggested as a crucial period for the development of WP SSTA during El Niño Modoki. The increased wind speed and evaporation might be responsible for the formation of WP SSTA. After the negative SSTA established, the suppressed convection would counteract the impact of evaporation anomaly and prevent the decreasing of WP SSTA.
Use of dynamical downscaling to improve the simulation of Central U.S. warm season precipitation in CMIP5 models
Authors: Harding Keith J. , Snyder Peter K. , Liess Stefan 
Published: November 2013

AbstractDespite supporting exceptionally productive agricultural lands, the Central U.S. is susceptible to severe droughts and floods. Such precipitation extremes are expected to worsen with climate change. However, future projections are highly uncertain as global climate models (GCMs) generally fail to resolve precipitation extremes. In this study, we assess how well models from the Coupled Model Intercomparison Project Phase 5 (CMIP5) simulate summer means, variability, extremes, and the diurnal cycle of Central U.S. summer rainfall. Output from a subset of historical CMIP5 simulations are used to drive the Weather Research and Forecasting model to determine whether dynamical downscaling improves the representation of Central U.S. rainfall. We investigate which boundary conditions influence dynamically downscaled precipitation estimates and identify GCMs that can reasonably simulate precipitation when downscaled. The CMIP5 models simulate the seasonal mean and variability of summer rainfall reasonably well but fail to resolve extremes, the diurnal cycle, and the dynamic forcing of precipitation. Downscaling to 30 km improves these characteristics of precipitation, with the greatest improvement in the representation of extremes. Additionally, sizeable diurnal cycle improvements occur with higher (10 km) resolution and convective parameterization disabled, as the daily rainfall peak shifts 4 h closer to observations than 30 km resolution simulations. This lends greater confidence that the mechanisms responsible for producing rainfall are better simulated. Because dynamical downscaling can more accurately simulate these aspects of Central U.S. summer rainfall, policymakers can have added confidence in dynamically downscaled rainfall projections, allowing for more targeted adaptation and mitigation.

AbstractThe impact of Southern California (SoCal) anthropogenic emissions on ozone (O3) in the mountain states in May 2010 is studied using the Sulfur Transport and Deposition Model. We identified two to six major transport events from SoCal to different subregions in the mountain states, with transport times of 0–2 days indicated by trajectories, time‐lag correlations, and forward/adjoint sensitivities. Based on forward sensitivity analysis, the contributions from SoCal anthropogenic emissions to the monthly mean daily maximum 8 h average (MDA8) surface O3 in the mountain states decrease with distance from SoCal, and they range from <1 ppbv (in Wyoming) to 15 ppbv (in western Arizona). These contributions show medium (>0.6) to strong (>0.8) positive correlations with the modeled total surface MDA8 O3. For the most strongly affected states of Arizona and New Mexico, these contributions have median values of ~3, ~2, ~5, and ~15 ppbv when the total surface MDA8 O3 exceeded thresholds of 60, 65, 70, and 75 ppbv, respectively. Surface MDA8 O3 values in SoCal show strong nonlinear responses to varied magnitudes of perturbation (e.g., ±50% and 100%) in SoCal anthropogenic emissions and weak nonlinear responses in the mountain states. Case studies show that different scales of transport (e.g., trans‐Pacific, stratospheric intrusions, and interstate) can be dynamically and chemically coupled and simultaneously affect O3 in the mountain states when the meteorological conditions are favorable. During some of these strong transport periods, the contributions of SoCal anthropogenic emissions to hourly O3 in the mountain states can exceed 20 ppbv, close to the magnitude during a summer event reported by Langford et al. (2010). Satellite observations from the Tropospheric Emission Spectrometer and the Measurements of Pollution in the Troposphere multispectral retrievals qualitatively demonstrate large and interstate scales of transport, respectively. Suggestions are made for future satellite missions to measure O3 with improved spatial coverage, temporal frequency, and near‐surface sensitivity to provide better observational constraints on interstate pollution transport studies.

Published: November 2013

BackgroundSinonasal melanoma (SNM) is a rare malignancy that commonly presents at an advanced age and has a slight male predominance. Local recurrence has been implicated as a major reason for treatment failure, and there are poor reported 5‐year survival rates. We analyzed the impact of specific location within the sinonasal region on the survival of this rare malignancy.MethodsThe U.S. National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) registry was used to extract data on SNM between 1973 and 2009. Survival trends and hazard ratios (HRs) were calculated to compare the prognostic implications of involvement of varying areas of the sinonasal tract.ResultsA total of 567 cases were identified. Females constituted 56.44% patient. Disease‐specific survival (DSS) at 5 years was 36.66% for patients diagnosed with nasal cavity disease, 23.80% for patients with maxillary sinus tumors, and 18.20% for patients with ethmoid sinus disease. Patients showing evidence of overlapping sinus involvement had approximate 1‐year survival of 54.45% and none survived beyond 49 months. HRs for maxillary sinus, ethmoid sinus, and overlapping sinus disease were 1.34, 1.60, and 2.30, respectively. All DSSs and HRs were statistically significant (p < 0.05). There was a higher proportion of earlier‐stage disease in the nasal cavity compared to the most common paranasal sinus region (p < 0.05).ConclusionPrognosis in SNM is dependent on the anatomic subsite. Paranasal sinus involvement indicates a poorer prognosis when compared to nasal cavity disease. Patients presenting with overlapping sinus involvement have the poorest prognosis.

Authors: Hur Kevin , Liang Jonathan , Lin Sandra Y. 
Published: November 2013

BackgroundThe objective of this work was to systematically review existing literature on the association between allergic rhinitis (AR) and secondhand smoking (SHS) in children and adults.MethodsWe performed a literature search encompassing the last 25 years in PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane CENTRAL, Web of Science, Scopus, and EMBASE. Inclusion criteria included English language papers containing original human data with greater than 6 subjects. Data was systematically collected on study design, patient demographics, clinical characteristics/outcomes, and level‐of‐evidence (Oxford Center of Evidence‐Based Medicine). Quality assessment of the studies was performed using the Newcastle‐Ottawa scale. Two investigators independently reviewed all manuscripts.ResultsThe initial search yielded 590 abstracts, of which 40 articles were included. 12 (37.5%) of the 32 articles studying children and 5 (62.5%) of the 8 articles studying adults showed a statistically significant association between AR and SHS. One article was a prospective cohort study (Level 2b) and all other articles were case‐control studies (Level 3b). For characterizing AR, 10 (25%) studies included skin‐prick testing and 5 (12.5%) used in vitro testing. For determining presence of SHS, 39 (97.5%) of the studies used questionnaires and 1 article used a cotinine/creatinine ratio.ConclusionThis review demonstrated a majority of adult studies vs a minority of children studies found a significant association between AR and SHS. However, the percent difference between age groups was not statistically significant. Further higher‐quality studies with validated methods for diagnosing AR and quantifying SHS exposure should be performed to better evaluate the relationship between AR and SHS in adults and children.
Nanoparticle‐Imprinted Polymers for Size‐Selective Recognition of Nanoparticles
Authors: Kraus‐Ophir Shlomit , Witt Julia , Wittstock Gunther , Mandler Daniel 
Published: November 2013

AbstractCitrate‐stabilized gold nanoparticles 15 nm and 33 nm in diameter were transferred concomitantly with a monolayer of positively charged polyaniline by Langmuir–Blodgett transfer at pH 5 onto a conducting indium‐doped tin oxide (ITO) support. Films consisting of one to three layers of polyaniline with thicknesses of 1–3 nm were prepared and characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM), and X‐ray photoelectron spectroscopy. After electro‐oxidation of the Au nanoparticles in 0.1 MKCl, cavities were left behind in the film that could be analyzed by SEM. These cavities were able to recapture analyte nanoparticles from a solution of pH 10 and showed size‐exclusion properties. The amount of nanoparticles taken up by the cavities was conveniently analyzed by measuring the charge associated with the electro‐oxidation of these particles in 0.1 MKCl after the film had been rinsed with water. The size‐exclusion properties improved with the number of Langmuir–Blodgett layers transferred.
Geophysical Observations at Archaeological Sites: Estimating Informational Content
Authors: Eppelbaum Lev V. 
Published: November 2013

ABSTRACTThe application of geophysical methods to archaeological sites is limited by physical, environmental, economic and time considerations. The presence of numerous kinds of noise means that in many cases the archaeological targets and surrounding media are best approached as probabilistic objects, such that the amount of information potentially available from different geophysical methods can be estimated by probabilistic and statistical methods, including the risks associated with this decision‐making. Here it is shown that simple informational and probabilistic criteria can be applied to formalize the information that can be obtained by applying different geophysical methods. To assess their relative value, geophysical methods, geophysical information and cost and time factors are convoluted in order to generate integrated parameters. This theoretical presentation of the information parameters is illustrated by the calculation of actual results. The solution to this ‘four colour’ mathematical problem shows that two independent geophysical methods are sufficient to characterize the archaeological potential of a site.

Pyridinium‐Fused Pyridinone: A Novel “Turn‐on” Fluorescent Chemodosimeter for Cyanide
Authors: Li Junbo , Gao Junkuo , Xiong Wei‐Wei , Li Pei‐Zhou , Zhang Huacheng , Zhao Yanli , Zhang Qichun 
Published: November 2013

AbstractA new chemodosimeter based on pyridinium‐fused pyridinone iodide (PI) has been obtained through a “clean reaction” method. This compound can detect CN− in aqueous solution with a high selectivity and rapid response. The detection of CN− occurs through the nucleophilic attack of CN− on the CN bond, which induces the destruction of the π‐conjugation on the pyridinium ring. Support of this detection mechanism was obtained by 1H NMR titration, HR‐MS, and DFT calculations. Upon the addition of 10 equivalents CN− to a solution of PI in THF/H2O (1:1, v/v), a 57‐fold enhancement in fluorescence intensity was observed at the maximum emission wavelength of 457 nm. Meanwhile, the maximum absorption wavelength was also blue‐shifted from 447 nm to 355 nm. Other common anions such as BF4−, PF6−, F−, Cl−, Br−, I−, H2PO4−, ClO4−, CH3COO−, NO2−, N3−, and SCN− had little effect on the detection of CN−. The response time of PI for CN− was less than 5 seconds. The detection limit was calculated to be 5.4×10−8 M, which is lower than the maximum permission concentration in drinking water (1.9 μM) set by the World Health Organization (WHO).
Stability Criterion of 2‐D Positive Systems with Unbounded Delays Described by Roesser Model
Authors: Liu Xingwen 
Published: November 2013

AbstractThis paper addresses the asymptotic stability issue of two‐dimensional (2‐D) positive systems with delays described by the Roesser model. The delays are time‐varying and may be unbounded. A necessary and sufficient stability condition is established, which determines if the considered system is asymptotically stable for all delays satisfying a sector bound constraint. The result is formulated as a linear programming problem and is hence computationally friendly. An example illustrates the theoretical result.
Flocking of Multi‐Agents Following a Leader with Adaptive Protocol in a Noisy Environment
Authors: Li Shukai , Liu Xinzhi , Tang Wansheng , Zhang Jianxiong 
Published: November 2013

AbstractThis paper investigates the flocking problem of multi‐agents following a leader with communication delays in a noisy environment. Based on potential fields and the LaSalle‐type theorem for stochastic differential delay equations, by introducing the adaptive protocol compensating for the desired velocity, a new neighbor‐based flocking protocol is proposed such that all the agents move with a virtual leader's velocity almost surely, and avoidance of collision between the agents is ensured. A numerical example is given to illustrate the effectiveness of the proposed methods.
