International Continental Scientific Drilling Program (ICDP) drilled a complete succession of the lacustrine sediment sequence deposited during the last ~500,000 years in Lake Van, Eastern Anatolia (Turkey). Based on a detailed seismic site survey, two sites at a water depth of up to 360 m were drilled in summer 2010, and cores were retrieved from sub-lake-floor depths of 140 m (Northern Basin) and 220 m (Ahlat Ridge). To obtain a complete sedimentary section, the two sites were multiple-cored in order to investigate the paleoclimate history of a sensitive semi-arid region between the Black, Caspian, and Mediterranean seas. Further scientific goals of the PALEOVAN project are the reconstruction of earthquake activity, as well as the temporal, spatial, and compositional evolution of volcanism as reflected in the deposition of tephra layers. The sediments host organic matter from different sources and hence composition, which will be unravelled using biomarkers. Pathways for migration of continental and mantle-derived noble gases will be analyzed in pore waters. Preliminary 40Ar/39Ar single crystal dating of tephra layers and pollen analyses suggest that the Ahlat Ridge record encompasses more than half a million years of paleoclimate and volcanic/geodynamic history, providing the longest continental record in the entire Near East to date.

IODP Expedition 340T: Borehole Logging at Atlantis Massif Oceanic Core Complex
Authors: Blackman D. , Slagle A. , Harding A. , Guerin G. , McCaig A.
Published: March 2014

Integrated Ocean Drilling Program (IODP) Expedition 340T returned to the 1.4-km-deep Hole U1309D at Atlantis Massif to carry out borehole logging including vertical seismic profiling (VSP). Seismic, resistivity, and temperature logs were obtained throughout the geologic section in the footwall of this oceanic core complex. Reliable downhole temperature measurements throughout and the first seismic coverage of the 800–1400 meters below seafloor (mbsf) portion of the section were obtained. Distinct changes in velocity, resistivity, and magnetic susceptibility characterize the boundaries of altered, olivine-rich troctolite intervals within the otherwise dominantly gabbroic se-quence. Some narrow fault zones also are associated with downhole resistivity or velocity excursions. Small deviations in temperature were measured in borehole fluid adjacent to known faults at 750 mbsf and 1100 mbsf. This suggests that flow of seawater remains active along these zones of faulting and rock alteration. Vertical seismic profile station coverage at zero offset now extends the full length of the hole, including the uppermost 150 mbsf, where detachment processes are expected to have left their strongest imprint. Analysis of wallrock properties, together with alteration and structural characteristics of the cores from Site U1309, highlights the likely interplay between lithology, structure, lithospheric hydration, and core complex evolution.

Published: March 2014

The Integrated Ocean Drilling Program’s (IODP) Expeditions 309 and 312 successfully completed the first sampling of an intact section of upper oceanic crust, through lavas and the sheeted dikes into the uppermost gabbros. Hole 1256D, which was initiated on the Ocean Drilling Program’s (ODP) Leg 206, now penetrates to > 1500 mbsf and > 1250 m sub-basement. The first gabbroic rocks were encountered at 1407 mbsf. Below this, the hole penetrates ~100 m into a complex zone of fractionated gabbros intruded into contact metamorphosed dikes.

Modeling bulk density and snow water equivalent using daily snow depth observations
Authors: McCreight J. L. , Small E. E.
Published: March 2014

Abstract. Bulk density is a fundamental property of snow relating its depth and mass. Previously, two simple models of bulk density (depending on snow depth, date, and location) have been developed to convert snow depth observations to snow water equivalent (SWE) estimates. However, these models were not intended for application at the daily time step. We develop a new model of bulk density for the daily time step and demonstrate its improved skill over the existing models. Snow depth and density are negatively correlated at short (10 days) timescales while positively correlated at longer (90 days) timescales. We separate these scales of variability by modeling smoothed, daily snow depth (long timescales) and the observed positive and negative anomalies from the smoothed time series (short timescales) as separate terms. A climatology of fit is also included as a predictor variable. Over half a million daily observations of depth and SWE at 345 snowpack telemetry (SNOTEL) sites are used to fit models and evaluate their performance. For each location, we train the three models to the neighboring stations within 70 km, transfer the parameters to the location to be modeled, and evaluate modeled time series against the observations at that site. Our model exhibits improved statistics and qualitatively more-realistic behavior at the daily time step when sufficient local training data are available. We reduce density root mean square error (RMSE) by 9.9 and 4.5% compared to previous models while increasing R2 from 0.46 to 0.52 to 0.56 across models. Focusing on the 21-day window around peak SWE in each water year, our model reduces density RMSE by 24 and 17.4% relative to the previous models, with R2 increasing from 0.55 to 0.58 to 0.71 across models. Removing the challenge of parameter transfer over the full observational record increases R2 scores for both the existing and new models, but the gain is greatest for the new model (R2 = 0.75). Our model shows general improvement over existing models when data are more frequent than once every 5 days and at least 3 stations are available for training.

The main objective of this work was to use the okra powder modified with citric acid as biosorbent for the removal of Cr(VI) from aqueous solutions. Samples of Cr(VI) solution were prepared by diluting the 100 ppm solution diluted from the 1000 ppm stock solution prepared with K2Cr2O7. The determination of Cr(VI) was performed spectrophotometrically by the method of complexation with 1,5-diphenylcarbazide, measuring the absorbance at a 540 nm wavelength. The experiments were conducted at 25 ± 1 °C; 2, 5, 7 and 8 initial pH; 10-240 minutes contact time and 0.05 g of adsorbent. The Freundlich and Langmuir models were used to fit the experimental data. The Freundlich model provided R2=0.9599, indicating adsorption on heterogeneous conditions. Analysis of fluorescence of X-rays, SEM and FTIR were used to prove the okra powder efficiency in the removal of Cr(VI) from aqueous solutions.
Reliability and Validity of PROMIS Cognitive Abilities and Cognitive Concerns Scales Among People with Multiple Sclerosis
Authors: Becker Heather , Stuifbergen Alexa , Lee HwaYoung , Kullberg Vicki
Published: March 2014

Background: Cognitive impairment is among the most debilitating outcomes of multiple sclerosis (MS). Although several neuropsychological tests and self-report cognitive measures have been used to assess cognitive impairment, they may not be sensitive to change over time, or may not be feasible to administer in a clinical setting. The purpose of this study was to assess the reliability and validity of the 8-item PROMIS Cognitive Abilities and Cognitive Concerns Scales in a large community-based sample of people with MS. The PROMIS Cognitive Abilities and Cognitive Concerns Scales derive from the National Institutes of Health–funded Patient Reported Outcomes Measurement Information System (PROMIS), an item repository that capitalizes on recent psychometric advances to produce short, psychometrically sound health measures.

Methods: Mailed survey data were collected from 322 individuals recruited from two National Multiple Sclerosis Society chapters in a southwestern state.

Results: Both cognitive scales demonstrated high internal consistency reliability and were moderately correlated with self-reported depressive symptoms, self-efficacy, barriers to health promotion, health, and functional status (all correlation coefficients >0.35). In hierarchical regression analysis, the PROMIS Cognitive Concerns score added significant unique variance to the prediction of MS Incapacity Status after controlling for self-reported depressive symptoms, exercise, spiritual growth, and global health. Those who were unemployed owing to their disabilities had significantly lower PROMIS Cognitive Abilities scores and higher Cognitive Concerns scores than those who were working or those who were retired or not working for other reasons.

Conclusions: The PROMIS Cognitive Abilities and Cognitive Concerns Scales are short, psychometrically sound measures that assess an important dimension of functioning and health for people with MS.
Thermal stability of Ag films with various interface layers

Published: March 2014

The effects of Pd, Ni, Nb, and Ti interface layers on the thermal stability of Ag films were investigated, and those metals that are appropriate for the interface layers were summarized. The results indicated that Ti and Nb interface layers resulted in thermally stable Ag films by improving the adhesion strength of the Ag films to SiO2 substrates and by enhancing the crystal orientation of Ag(111). It was determined that appropriate interface layer metals for Ag film should have a large Gibbs free energy of formation for the oxide and an appropriate atomic diameter ratio of d

Published: March 2014

To obtain a new scintillator with a higher gamma-ray stopping power than conventional Ce:Gd3Al2Ga3O12 (Ce:GAGG), which has excellent light output and energy resolution, new scintillators based on Ce:GAGG, Ce:Gd3Al2Mg0.5Hf0.5Ga2O12, and Ce:Gd3Al2Mg0.5Zr0.5Ga2O12 were grown by the micro-pulling down method as the first step. We found that the emission wavelengths of these crystals became slightly longer than that of Ce:GAGG by approximately 10–20 nm owing to the change in energy band structure.
Formation of ZnO luminescent films on SiN films for light source of high-resolution optical microscope
Authors: Miyake Aki , Kanamori Satoshi , Nawa Yasunori , Inami Wataru , Kominami Hiroko , Kawata Yoshimasa , Nakanishi Yoichiro
Published: March 2014

We fabricated ZnO/SiN films for use as a light source of a high-resolution optical microscope and characterized the properties of the films, and demonstrated images obtained with the microscope using the fabricated ZnO/SiN films. A 100-nm-thick ZnO film deposited on a SiN film showed a much higher CL intensity than the SiN film, and it was enhanced by high-temperature annealing of the ZnO film. Electron beam excitation assisted optical microscope images of gold particles of 200 nm diameter taken using the ZnO/SiN film and SiN indicated that the ZnO/SiN films can provide a higher signal-to-noise (S/N) ratio and a higher frame rate than the SiN film. It was shown that the dynamic observation of living cells becomes possible using the high-resolution optical microscope with a bright light source. Moreover, this fact promises that such optical microscope can contribute to progress in the medical and biological fields.
Exploring Video Abstracts in Science Journals: An Overview and Case Study
Authors: Spicer Scott
Published: March 2014

INTRODUCTION The video abstract has emerged in recent years as a new way of communicating the results of scholarly enquiry. For library-based journal publishers who want to support multimodal scholarship, it is useful to understand the potential benefit and impact of incorporating video abstracts into their publications. This paper provides an overview of the growth of video abstracts in science scholarship, and presents a single journal case study that compares the use and potential impact of video abstracts hosted on both YouTube and on a journal’s own website. METHODS For the case study, video abstract usage data for the New Journal of Physics (NJP) was gathered from both YouTube and the NJP native platform and then correlated using a Spearman rank correlation coefficient test to analyze viewing usage. Viewership data from both platforms was also correlated with article usage counts using Spearman to study the relationship between article usage and corresponding video abstract usage. RESULTS Users predominantly accessed the journal’s hosted video abstracts instead of the abstracts posted on YouTube. However, there was a moderate positive correlation comparing view counts of the same video abstracts across both platforms, suggesting proportionate use of both platforms. In addition, the top 25 and 100 read articles had a significantly higher presence of video abstracts than articles overall in the data set, although a specific reason for that relationship cannot be identified. DISCUSSION & CONCLUSION Video abstracts are a natural evolution of science communication into multimodal environments. Publishing trends will likely continue to grow gradually, with appreciation for non-traditional scholarship (multimodal scholarship) and new measures for assessing impact (altmetrics) potentially encouraging greater adoption. Librarybased journal publishers should consider investing in software that offers dynamic media integration, offering the video abstract option to their authors, and leveraging YouTube to further raise the visibility of their authors’ research articles and publication. Library-based publishers should have some expectation that the video abstracts will be viewed relatively proportionally across platforms (i.e. a video abstract that receives a higher or lower view count on the journal’s website is moderately more likely to also receive a higher or lower view count on YouTube), with the majority of total views (for all videos) coming from the journal’s website. Subject and media librarians should become more aware of these emerging practices to support the video abstract publication and creation needs of their research communities.
Scholarly Communication at Canadian Research Libraries: Conversations with Librarians
Authors: Burpee K Jane , Fernandez Leila
Published: March 2014

INTRODUCTION The landscape of librarianship in relation to the practice of scholarly communication is evolving. The objectives of this study were to investigate: the scope of scholarly communication activities within Canadian research libraries; the organizational structures in place to support them; and the roles of librarians who participate in them. Key challenges to its advancement and how librarians envision its future were also investigated. METHODS Twenty-nine academic librarians from Canadian Association of Research Libraries member institutions participated in semi-structured, open-ended interviews. Interviews were analyzed for recurring themes. RESULTS Participants outlined initiatives, services, and structures to support scholarly communication at their institutions. Solo scholarly communication librarians, specialized teams, and committees were identified as primary structures. Liaison librarians play an essential supporting role regardless of structure. Individually, librarians are seen to have an impact as leaders and advocates in promoting scholarly communication. The concept of “librarian as researcher” is also important. Participants shared a desire for better communication and collaboration in this area. Many participants saw the need for standardized assessment and evaluation methods. Participants enumerated their greatest challenges and provided suggestions for addressing them in the future. CONCLUSION This study demonstrates that organizational structure can enhance scholarly communication activities in libraries. Leadership both at the personal and collective level is necessary to provide an impetus for scholarly communication activities. Librarians should be knowledgeable about the issues and be ready to deliver the “pitch.” Strengthening collaboration and communication among Canadian librarians is essential for moving the scholarly communication agenda forward.

Exploratory study of the effectiveness of a professional development program on the academic achievement and classroom behavior of students with Fetal Alcohol Spectrum Disorder in British Columbia, Canada. The International Journal Of Alcohol And Drug Research, 3(1), 25-34. doi:10.7895/ijadr.v3i1.119Aim: Exploratory assessment of a professional development program for teachers supporting students with Fetal Alcohol Spectrum Disorder (FASD).Design: A mixed-method research design, using qualitative descriptive and quasi-experimental methods, was employed.Setting: The study occurred in selected public elementary schools in a British Columbia school district.Participants: Elementary school teachers and students with FASD.Measures: For the quasi-experimental component, the Behavior Assessment System for Children, 2nd edition (BASC-2) Teacher Rating Scale (TRS), and Student Observation System assessed classroom behavior. The Curriculum-Based Measure (CBM) assessed reading, writing, and mathematics skills of children with FASD. Inductive thematic analysis was used to derive themes from teachers’ interviews.Findings: A statistically significant improvement in intervention students’ classroom behavior was observed. An improvement of moderate effect size was seen for academic achievement, although the changes were not statistically significant. Teachers reported that the professional development program changed their teaching practice. Intervention teachers described how they redefined students’ behaviors and adapted their teaching practice to accommodate students’ neurological deficits.Conclusions: The results provide preliminary support for the effectiveness of the professional development program for elementary school teachers teaching students with FASD. Further research is needed with a larger sample size to reduce type II error.
“Doc, I didn’t know I was pregnant. Does my baby have fetal alcohol spectrum disorder?”

Green, C., & Cook, J. (2014). “Doc, I didn’t know I was pregnant. Does my baby have fetal alcohol spectrum disorder?”. The International Journal Of Alcohol And Drug Research, 3(1), 117-120. doi:10.7895/ijadr.v3i1.176How much alcohol is “safe” during pregnancy? This is a question for which there is no conclusive answer. Although no mother wants to intentionally harm her baby, the reality is that consuming alcohol during pregnancy can lead to a variety of complex developmental disabilities, collectively termed Fetal Alcohol Spectrum Disorder (FASD). The precise dosimetry data for the timing and dose of alcohol in pregnancy is unknown, but several features of alcohol metabolism are well characterized and have significant implications for alcohol’s deleterious effects on the developing fetus. There are a number of critical periods in embryonic development, which can be brief or prolonged and that correspond to specific tissues and structures (organ systems). Alcohol at any one of these critical periods can have significant downstream effects on typical fetal development. Alcohol teratogenicity does not produce a single abnormality, but instead can lead to a cluster of birth defects and/or neurodevelopmental abnormalities (i.e., FASD). Each of these cognitive or behavioral problems can vary in its expression, from severe and obvious early in life, to subtle and apparent only years after birth. Based on the variability among women and their fetuses, genetics and environmental influences, it is very unlikely that “absolute risk” for alcohol and pregnancy will ever be established. The age-old question, “How much is too much?”, will also remain unanswered. The best advice: “NO exposure equals NO risk.”
Regional flood frequency analysis using kernel‐based fuzzy clustering approach
Authors: Basu Bidroha , Srinivas V. V.
Published: March 2014

Regionalization approaches are widely used in water resources engineering to identify hydrologically homogeneous groups of watersheds that are referred to as regions. Pooled information from sites (depicting watersheds) in a region forms the basis to estimate quantiles associated with hydrological extreme events at ungauged/sparsely gauged sites in the region. Conventional regionalization approaches can be effective when watersheds (data points) corresponding to different regions can be separated using straight lines or linear planes in the space of watershed related attributes. In this paper, a kernel‐based Fuzzy c‐means (KFCM) clustering approach is presented for use in situations where such linear separation of regions cannot be accomplished. The approach uses kernel‐based functions to map the data points from the attribute space to a higher‐dimensional space where they can be separated into regions by linear planes. A procedure to determine optimal number of regions with the KFCM approach is suggested. Further, formulations to estimate flood quantiles at ungauged sites with the approach are developed. Effectiveness of the approach is demonstrated through Monte‐Carlo simulation experiments and a case study on watersheds in United States. Comparison of results with those based on conventional Fuzzy c‐means clustering, Region‐of‐influence approach and a prior study indicate that KFCM approach outperforms the other approaches in forming regions that are closer to being statistically homogeneous and in estimating flood quantiles at ungauged sites.

Iron is a limiting micronutrient for primary production in the Ross Sea, Antarctica. Recent observations reveal low dissolved Fe (dFe) concentrations in the Ross Sea polynya following high initial rates of primary production in summer, after the dFe winter reserve has been consumed. Significant new sources of dFe are therefore required to further sustain phytoplankton blooms. Iron from aeolian sand and dust (ASD) released from melting sea ice is one potential source. To constrain aeolian Fe inputs, we determined ASD mass accumulation rates and the total and soluble Fe content of ASD on sea ice in McMurdo Sound, southwestern (SW) Ross Sea. The mean mass accumulation rate was ~1.5 g m−2 yr−1, total Fe content of this ASD was 4 ± 1 wt %, and the percentage of soluble Fe was 11 ± 1%. Our mean estimate of the bulk aeolian dFe flux of 122.1 µmol m−2 yr−1 for the McMurdo Sound region suggests that aeolian Fe can support between 9.0 × 109 and 4.1 × 1011 mol C yr−1 (0.1–4.9 Tg C yr−1) of new primary production. This equates to only ~15% of new primary production in the SW Ross Sea, suggesting that aeolian dFe is a minor component of seasonal Fe supply. The very high ASD accumulation on sea ice in McMurdo Sound compared to other regions of Antarctica suggests that our results represent the upper limit of dFe supply to the ocean from this source in the Ross Sea.

In the tropical Andes, there have been very few systematic studies aimed at understanding the biomass burning dynamics in the area. This paper seeks to advance on our understanding of burning regimes in this region, with the first detailed and comprehensive assessment of fire occurrence and the derived gross biomass burning emissions of an area of the Peruvian tropical Andes. We selected an area of 2.8 million hectares at altitudes over 2000 m. We analyzed fire occurrence over a 12 year period with three types of satellite data. Fire dynamics showed a large intra‐annual and interannual variability, with most fires occurring May–October (the period coinciding with the dry season). Total area burned decreased with increasing rainfall until a given rainfall threshold beyond which no relationship was found. The estimated fire return interval (FRI) for the area is 37 years for grasslands, which is within the range reported for grasslands, and 65 years for forests, which is remarkably shorter than other reported FRI in tropical moist forests. The greatest contribution (60–70%, depending on the data source) to biomass burning emissions came from burned montane cloud forests (4.5 million Mg CO2 over the study period), despite accounting for only 7.4–10% of the total burned area. Gross aboveground biomass emissions (7.55 ± 2.14 Tg CO2; 0.43 ± 0.04 Tg CO; 24,012 ± 2685 Mg CH4 for the study area) were larger than previously reported for the tropical Andes.
Field‐aligned currents during the extreme solar minimum between the solar cycles 23 and 24

Published: March 2014

The solar minimum between solar cycles 23 and 24 was unusually long and deep. The upward region‐1 (R1) field‐aligned current (FAC) response to this extreme solar minimum was investigated using Defense Meteorological Satellite Program observations. The solar cycle responses on the dayside are different than those on the nightside. The field‐aligned current density (J//) on the dayside, at 12–17 magnetic local time (MLT), peaks in the declining phase of the solar cycle, in 2003, when the solar wind speed also peaks, whereas J// on the nightside, at 18–23 MLT, appears insensitive to the solar cycle. In 1995–2010, J// at 15–17 MLT reaches the lowest value during the extreme solar minimum in 2009, when the solar wind speed also reaches the lowest value. At 12–17 MLT, R1 is located mostly on open field lines or at the boundary layer, where the current is driven mostly by the velocity shear at the magnetopause boundary. However, on the nightside, R1 is located mostly on the closed field lines where J// is not driven directly and immediately by the solar wind. The nightside current width (Λ) exhibits a solar cycle effect such that Λ is smaller at the solar minimum and smallest in 2009. However, the dayside Λ exhibits little solar cycle effect. As a result, the FAC intensity (latitudinally integrated J//) exhibits a solar cycle variation at all local times and the FAC intensity is lower during the extreme solar minimum than that of the previous solar minimum.

Published: March 2014

The first of a new generation of microwave sounders was launched aboard the Suomi‐National Polar‐Orbiting Partnership satellite in October 2011. The Advanced Technology Microwave Sounder (ATMS) combines the capabilities and channel sets of three predecessor sounders into a single package to provide information on the atmospheric vertical temperature and moisture profiles that are the most critical observations needed for numerical weather forecast models. Enhancements include size/mass/power approximately one third of the previous total, three new sounding channels, the first space‐based, Nyquist‐sampled cross‐track microwave temperature soundings for improved fusion with infrared soundings, plus improved temperature control and reliability. This paper describes the ATMS characteristics versus its predecessor, the advanced microwave sounding unit (AMSU), and presents the first comprehensive evaluation of key prelaunch and on‐orbit performance parameters. Two‐year on‐orbit performance shows that the ATMS has maintained very stable radiometric sensitivity, in agreement with prelaunch data, meeting requirements for all channels (with margins of ~40% for channels 1–15), and improvements over AMSU‐A when processed for equivalent spatial resolution. The radiometric accuracy, determined by analysis from ground test measurements, and using on‐orbit instrument temperatures, also shows large margins relative to requirements (specified as <1.0 K for channels 1, 2, and 16–22 and <0.75 K for channels 3–15). A thorough evaluation of the performance of ATMS is especially important for this first proto‐flight model unit of what will eventually be a series of ATMS sensors providing operational sounding capability for the U.S. and its international partners well into the next decade.
The Venus nighttime atmosphere as observed by the VIRTIS‐M instrument. Average fields from the complete infrared data set

We present and discuss here the average fields of the Venus atmosphere derived from the nighttime observations in the 1960–2350 cm−1 spectral range by the VIRTIS‐M instrument on board the Venus Express satellite. These fields include: (a) the air temperatures in the 1–100 mbar pressure range (~85–65 km above the surface), (b) the altitude of the clouds top, and (c) the average CO mixing ratio. A new retrieval code based on the Bayesian formalism has been developed and validated on simulated observations, to statistically assess the retrieval capabilities of the scheme once applied to the VIRTIS data. The same code has then been used to process the entire VIRTIS‐M data set. Resulting individual retrievals have been binned on the basis of local time and latitude, to create average fields. Air temperature fields confirm the general trends previously reported in Grassi et al. (2010), using a simplified retrieval scheme and a more limited data set. At the lowest altitudes probed by VIRTIS (~65 km), air temperatures are strongly asymmetric around midnight, with a pronounced minima at 3LT, 70°S. Moving to higher levels, the air temperatures first become more uniform in local time (~75 km), then display a colder region on the evening side at the upper boundary of VIRTIS sensitivity range (~80 km). As already shown by Ignatiev et al. (2008) for the dayside, the cloud effective altitude increases monotonically from the south pole to the equator. However, the variations observed in night data are consistent with an overall variation of just 1 km, much smaller than the 4 km reported for the dayside. The cloud altitudes appear slightly higher on the evening side. Both observations are consistent with a less vigorous meridional circulation on the nightside of the planet. Carbon monoxide is not strongly constrained by the VIRTIS‐M data. However, average fields present a clear maximum of 80 ppm around 60°S, well above the retrieval uncertainty. Once the intrinsic low sensitivity of VIRTIS data in the region of cold collar is kept in mind, this datum is consistent with a [CO] enrichment toward the poles driven by meridional circulation.
Daily evaporation from drying soil: Universal parameterization with similarity
Authors: Brutsaert Wilfried
Published: March 2014

With supporting experimental evidence from three separate field studies of daily mean evaporation from bare soil with vastly different physical characteristics, it is shown that the process can be described as isothermal linear diffusion in a finite depth domain. The resulting solution leads directly to similarity variables and thus a universal parameterization, which should in principle be applicable to most field soils. In addition, a closed form expression is presented to estimate the weighted mean diffusivity for exponential type soil water diffusivities. In this solution, the widely used square root of inverse time proportionality of this phenomenon is its short time version, whereas the exponential decay proportionality, proposed however by several authors for vegetated surfaces, is its long time version. It appears that in many situations the soil layer contributing to evaporation is fairly shallow and only a few tens of centimeters thick.
Systematic model forecast error in Rossby wave structure

Published: March 2014

Diabatic processes can alter Rossby wave structure; consequently, errors arising from model processes propagate downstream. However, the chaotic spread of forecasts from initial condition uncertainty renders it difficult to trace back from root‐mean‐square forecast errors to model errors. Here diagnostics unaffected by phase errors are used, enabling investigation of systematic errors in Rossby waves in winter season forecasts from three operational centers. Tropopause sharpness adjacent to ridges decreases with forecast lead time. It depends strongly on model resolution, even though models are examined on a common grid. Rossby wave amplitude reduces with lead 5 days, consistent with underrepresentation of diabatic modification and transport of air from the lower troposphere into upper tropospheric ridges, and with too weak humidity gradients across the tropopause. However, amplitude also decreases when resolution is decreased. Further work is necessary to isolate the contribution from errors in the representation of diabatic processes.
One‐Step Synthesis of Methanesulfonyloxymethyl Ketones via Gold‐Catalyzed Oxidation of Terminal Alkynes: A Combination of Ligand and Counter Anion Enables High Efficiency and a One‐Pot Synthesis of 2,4‐Disubstituted Thiazoles

By using Mor‐DalPhos as the P,N‐bidentate ligand and mesylate as the counter ion, the resulting gold(I) complex catalyzes efficient oxidative transformations of various terminal alkynes into synthetically versatile methanesulfonyloxymethyl ketones. The mild reaction conditions and high efficiency permit the one‐pot synthesis of a range of valuable 2,4‐disubstituted thiazoles by subjecting the resulting reaction mixture to a further condensation with thioamides under mild conditions.

The readily available carbonyl(pentamethylcyclopentadienyl)cobalt diiodide complex [Cp*Co(CO)I2] was successfully utilized as the precursor of a cationic cobalt(III) active catalyst for directed CH bond functionalization. The complex Cp*Co(CO)I2 (2.5–1.25 mol%), in combination with silver hexafluoroantimonate (AgSbF6) and potassium acetate (KOAc), efficiently catalyzed the directed C‐2 selective amidation of indoles with sulfonyl azides, and the corresponding products were obtained in 85–98 % yield.

H‐Phosphinates react with alkenes and alkynes using catalytic manganese(II) acetate. Under stoichiometric conditions with manganese(III) acetate or with catalytic manganese(II) acetate+excess manganese(II) oxide various reactions like arylation or cyclization through radical oxidative arylation can take place. Whereas the chemistry of manganese is already well developed for the functionalization of H‐phosphonates, the present methodology provides an unprecedented access to functionalized phosphinates in acceptable to good yields.
