Cytology of the fallopian tube: A screening model for high-grade serous carcinoma
Authors: Dhanani Maya , Nassar Aziza , Charles Mélissa S. , Dinh Tri
Published: November 2018

Ovarian cancer is a heterogeneous disease having the highest gynecologic fatality in the United States with a 5-year survival rate of 46.5%. Poor overall prognosis is mostly attributed to inadequate screening tools, and the majority of diagnoses occur at late stages of the disease. Due to genetic and biological underpinnings, ovarian high-grade serous carcinomas (HGSC) have etiologic evidence in the distal fallopian tube. Fallopian tube screening modalities are aggressively investigated, but few describe cytological characteristics of benign tubal specimens to help in the comparative detection of HGSC precursor cells. Here, we describe fimbrial cytomorphological and nuclear features of tubal specimens (n = 75) from patients clinically indicated for salpingectomy, bilateral or unilateral salpingo-oophorectomy, and hysterectomies for any diagnosis other than ovarian or peritoneal cancer. Fallopian tube histology was used as the diagnostic reference. A total of 75 samples had benign diagnoses. The benign cytological characteristics of fimbrial tubal specimens included ciliated cells in clustered arrangements with mild nuclear membrane irregularity, mild anisonucleosis, round and/or oval nuclei, hyperchromatic chromatin, and mild nuclear membrane irregularity. In contrast, none of the cytology samples had spindle-shaped nuclei, significantly marked anisonucleosis (n = 1), nor had hypochromasia as a characteristic feature. These cytological characteristics could be a potential area of distinction from HGSC precursor cells. Our study establishes cytomorphological characteristics of nonmalignant tubal cells which help underscore the importance of distinguishing malignant HGSC precursors through fimbrial brush sampling in minimally invasive approach.
Artificial Neural Network (ANN) in a Small Dataset to determine Neutrality in the Pronunciation of English as a Foreign Language in Filipino Call Center Agents
Authors: Baquirin Rey Benjamin M. , Fernandez Proceso L.
Published: November 2018

Artificial Neural Networks (ANNs) have continued to be efficient models in solving classification problems. In this paper, we explore the use of an A NN with a small dataset to accurately classify whet her Filipino call center agentsâ€™ pronunciations are neutral or not based on their employerâ€™s standards. Isolated utterances of the

ten most commonly used words in the call center were recorded from eleven agents creating a dataset of

110 utterances. Two learning specialists were consulted to establish ground truths and Cohenâ€™s Kappa was computed as 0.82, validating the reliability of the dataset. The first thirteen Mel-Frequency Cepstral Coefficients (MFCCs) were then extracted from each word and an ANN was trained with Ten-fold Stratified Cross Validation.

Experimental results on the model recorded a classification accuracy of 89.60% supported by an overall F-Score

of 0.92.

Análise funcional comparativa de trecho da BR-116 no estado do Ceará
Authors: Silva Joyce Pascoal de Oliveira , Oliveira Francisco Heber Lacerda de , Araújo Carla Beatriz Costa de
Published: November 2018

Este trabalho consiste na realização de uma análise comparativa entre duas metodologias de avaliação funcional de pavimentos flexíveis, as quais foram executadas ao longo de um trecho da BR-116 no Estado do Ceará. Os métodos utilizados baseiam-se na execução de um inventário de patologias existentes na superfície da rodovia, com o objetivo de calcular índices que atribuem ao pavimento conceitos de degradação, são eles: o Índice de Gravidade Global (IGG) e o Índice do Estado da Superfície (IES). Enquanto o IGG é obtido mediante a classificação e contagem das ocorrências e a medição das flechas nas trilhas de roda, em superfícies de avaliação, o IES é obtido por meio de um Levantamento Visual Contínuo (LVC), em toda a extensão do trecho. Ao comparar os resultados obtidos para os dois índices, considerando segmentos aproximados, verificou-se divergência de conceitos em várias seções. Através do IES foi atribuída ao pavimento uma pior condição de degradação. Enquanto o IGG considerou 48% da extensão avaliada em estado Regular, 47% em estado Ruim e somente 5% em estado Péssimo; o IES considerou 51,6% em estado Ruim, 48,3% em estado Péssimo e apenas 0,1 em estado Regular. Esse fato pode estar relacionado à maior subjetividade do método LVC.
The impact of mineral dust on the day-to-day variability of stratiform cloud glaciation occurrence
Authors: Villanueva Diego , Heinold Bernd , Seifert Patric , Deneke Hartwig , Radenz Martin , Tegen Ina
Published: November 2018

Abstract. Two different A-Train satellite cloud phase products were analysed together with an aerosol model reanalysis to assess the global day-to-day variability of cloud thermodynamic phase. This variability was analysed for different mixing-ratios of fine and coarse mineral dust during the period 2007–2010 and within a temperature range from +3 °C to −42 °C. Night‑time stratiform clouds were analysed, including stratocumulus, altocumulus, altostratus and cirrus clouds. This analysis showed that the phase of stratiform clouds is highly dependent on temperature and latitude. However, at equal temperature the average occurrence of fully glaciated stratiform clouds was found to increase for higher dust mixing-ratios on a day-to-day basis at mid- and high latitudes. At −15 °C, the increment of ice cloud occurrence between the lowest and highest mixing-ratio was found to be higher for fine dust (+10 % to +18 % occurrence) than for coarse dust (+5 % to +10 %). Surprisingly, the increments were higher in remote regions (e.g. southern high latitudes) where the average dust-mixing ratios are low.
Using spectra characteristics to identify ice nucleating particle populations
during winter storms in the Alps
Authors: Creamean Jessie M. , Mignani Claudia , Bukowiecki Nicolas , Conen Franz
Published: November 2018

Abstract. One of the least understood cloud processes is modulation of their microphysics by aerosols, specifically of cloud ice by ice nucleating particles (INPs). To investigate INP impacts on cloud ice and subsequent precipitation formation, measurements in cloud environments are necessary but difficult given the logistical challenges associated with airborne measurements and separating interstitial aerosol from cloud residues. Additionally, determining the sources of INPs is important given the dependency of glaciation temperatures on the mineral or biological components and diversity of such INP populations. Here, we present results from a comparison of INP spectral characteristics in air, cloud rime, and fresh fallen snow for storm days at the High-Altitude Research Station, Jungfraujoch. The goal of the study was two-fold: (1) to assess variability in wintertime INP populations found in-cloud based on air mass direction during snowfall and (2) to evaluate INPs between different sample types using normalized differential INP spectra. INP freezing temperatures and concentrations were consistently higher on average from the southeast as compared to the northwest for rime, snow and especially aerosol samples which is likely a result of air mass influence from boundary layer terrestrial and marine sources in Southern Europe, the Mediterranean, and North Africa. For all three sample types combined, average onset freezing temperatures were −7.7 and −12 °C for southeasterly and northwesterly days, respectively, while INP concentrations were 3 to 20 times higher when winds arrived from the southeast. Southeasterly aerosol samples typically had bimodal freezing spectra – indicating a putative influence from biological sources – while bimodality of the rime and snow varied depending on meteorological context. Evaluating normalized differential INP spectra exhibited variable modality and shape – depending on the types of INPs present – and may serve as a viable method for comparing different sampling substances and assessing the possible mixed mineral and biological versus only biological contributions to INP sample populations.
Assessment of dicarbonyl contributions to secondary organic aerosols over China using RAMS-CMAQ
Authors: Li Jialin , Zhang Meigen , Tang Guiqian , Sun Yele , Wu Fangkun , Xu Yongfu
Published: November 2018

Abstract. The concentration of secondary organic aerosol (SOA) is underestimated by one to two orders of magnitude in current model studies. Recent research suggests that the aqueous irreversible uptake of dicarbonyls contributes to the production of SOA, although few models have included this pathway. Glyoxal, an important representative component of dicarbonyls in models, is significantly underestimated. We therefore incorporated the aqueous irreversible uptake of dicarbonyls into the regional air quality modeling system RAMS-CMAQ (the Regional Atmospheric Modeling System-Community Multiscale Air Quality) to evaluate the contribution of dicardonyls to SOA, and we then assess the impact of the underestimation of glyoxal on the production of SOA in China during two time periods: June 3 to July 11, 2014 (episode 1) and October 14 to November 14, 2014 (episode 2). When the aqueous irreversible uptake process was added, the modeled mean concentration of SOA in episode 1 increased by 1.57 μg/m3, which explains 15.0 % of the unaccounted source of SOA. By contrast, the increase in the concentration of SOA in episode 2 was small as a result of the lower liquid water content and the lower amount of dicarbonyls produced from biogenic precursors in the fall. On this basis, when the glyoxal simulation was improved, the modeled mean dicarbonyl-derived SOA (AORGCJ) increased by a factor of 2 in both episodes. AORGCJ in episode 1 contributed, on average, 39.0 % of the total concentration of SOA and the increase in this contribution represented 26.7 % of the unaccounted concentration of SOA, whereas the mean AORGCJ in episode 2 accounted for 18.5 % of total concentration of SOA. Based on the results for episode 1, the mean AORGCJ in summer over China was generally higher in the east than in the west, with the highest value (5–10 μg/m3) in the areas between the lower reaches of the Yellow and Yangtze rivers and in the Sichuan Basin. The contribution of AORGCJ to the concentration of SOA varied from 10 to 90 % throughout China, with the highest contributions (70–90 %) in the coastal regions and offshore along the East China Sea to the South China Sea and in the southwestern regions.

spaceborne missions such as Tropospheric Emissions: Monitoring Pollution
(TEMPO). The network currently comprises six tropospheric ozone lidars, four
of which are mobile instruments deploying to the field a few times per year,
based on campaign and science needs. In August 2016, all four mobile TOLNet
lidars were brought to the fixed TOLNet site of JPL Table Mountain Facility
for the 1-week-long Southern California Ozone Observation Project (SCOOP).
This intercomparison campaign, which included 400 h of lidar measurements
and 18 ozonesonde launches, allowed for the unprecedented simultaneous
validation of five of the six TOLNet lidars. For measurements between 3 and
10 km a.s.l., a mean difference of 0.7 ppbv (1.7 %), with a
root-mean-square deviation of 1.6 ppbv or 2.4 %, was found between the
lidars and ozonesondes, which is well within the combined uncertainties of
the two measurement techniques. The few minor differences identified were
typically associated with the known limitations of the lidars at the profile
altitude extremes (i.e., first 1 km above ground and at the instruments'
highest retrievable altitude). As part of a large homogenization and quality
control effort within the network, many aspects of the TOLNet in-house data
processing algorithms were also standardized and validated. This thorough
validation of both the measurements and retrievals builds confidence as to the
high quality and reliability of the TOLNet ozone lidar profiles for many
years to come, making TOLNet a valuable ground-based reference network for
tropospheric ozone profiling.
Aging aerosol in a well-mixed continuous flow tank reactor: An introduction of the activation time distribution
Authors: Friebel Franz , Mensah Amewu A.
Published: November 2018

Abstract. Simulating atmospheric aging processes in the laboratory under atmospheric conditions typically requires large aerosol chambers (several m3) in order to achieve extended observation times. We developed an experimental approach that enables long observation times in small chamber volumes by operating the aerosol chamber in a Continuous Flow Stirred Tank Reactor (CSTR) mode. We present a mathematical framework which allows the retrieval of data beyond calculating mean values using the newly introduced metric activation time (tact). This concept was developed and successfully tested to characterize the change in cloud condensation nuclei (CCN) activity of soot particles due to heterogeneous oxidation with ozone. We show that this concept can be applied to other systems investigating non-gradual transitions. The change in CCN-activity was parameterized with tact and agreed well with theoretical predictions. Furthermore we show how tact can be applied for the analysis of data originating from other oxidation flow reactors widely used in atmospheric sciences. This concept allows to explain discrepancies found in intercomparison of different chambers.
A perturbed biogeochemistry model ensemble evaluated against in situ and satellite observations
Authors: Anugerahanti Prima , Roy Shovonlal , Haines Keith
Published: November 2018

Abstract. The dynamics of biogeochemical models are determined by the mathematical
equations used to describe the main biological processes. Earlier studies
have shown that small changes in the model formulation may lead to major
changes in system dynamics, a property known as structural sensitivity. We
assessed the impact of structural sensitivity in a biogeochemical model of
intermediate complexity by modelling the chlorophyll and dissolved inorganic
nitrogen (DIN) concentrations. The model is run at five different
oceanographic stations spanning three different regimes: oligotrophic,
coastal, and the abyssal plain, over a 10-year timescale to observe the
effect in different regions. A 1-D Model of Ecosystem Dynamics, nutrient
Utilisation, Sequestration, and Acidification (MEDUSA) ensemble was used with
each ensemble member having a combination of tuned function parameterizations
that describe some of the key biogeochemical processes, namely nutrient
uptake, zooplankton grazing, and plankton mortalities. The impact is
quantified using phytoplankton phenology (initiation, bloom time, peak
height, duration, and termination of phytoplankton blooms) and statistical
measures such as RMSE (root-mean-squared error), mean, and range for
chlorophyll and nutrients. The spread of the ensemble as a measure of
uncertainty is assessed against observations using the normalized RMSE ratio
(NRR). We found that even small perturbations in model structure can produce
large ensemble spreads. The range of 10-year mean surface chlorophyll
concentration in the ensemble is between 0.14 and 3.69 mg m−3 at
coastal stations, 0.43 and 1.11 mg m−3 on the abyssal plain, and 0.004
and 0.16 mg m−3 at the oligotrophic stations. Changing both
phytoplankton and zooplankton mortalities and the grazing functions has the
largest impact on chlorophyll concentrations. The in situ measurements of
bloom timings, duration, and terminations lie mostly within the ensemble
range. The RMSEs between in situ observations and the ensemble mean and
median are mostly reduced compared to the default model output. The NRRs for
monthly variability suggest that the ensemble spread is generally narrow (NRR
1.21–1.39 for DIN and 1.19–1.39 for chlorophyll profiles, 1.07–1.40 for
surface chlorophyll, and 1.01–1.40 for depth-integrated chlorophyll). Among the five stations, the most reliable ensembles are
obtained for the oligotrophic station ALOHA (for the surface and integrated
chlorophyll and bloom peak height), for coastal station L4 (for inter-annual
mean), and for the abyssal plain station PAP (for bloom peak height). Overall
our study provides a novel way to generate a realistic ensemble of a
biogeochemical model by perturbing the model equations and parameterizations,
which will be helpful for the probabilistic predictions.
Vegetation and geochemical responses to Holocene rapid climate change in the Sierra Nevada (southeastern Iberia): the Laguna Hondera record

Abstract. High-altitude peat bogs and lacustrine records are very sensitive to climate
changes and atmospheric dust input. Recent studies have shown a close
relationship between regional climate aridity and enhanced eolian input to
lake sediments. However, changes in regional-scale dust fluxes due to
climate variability at short scales and how alpine environments were
impacted by climatic- and human-induced environmental changes are not
completely understood. Here we present a multi-proxy (palynological, geochemical and magnetic
susceptibility) lake sediment record of climate variability in the Sierra
Nevada (southeastern Iberian Peninsula) over the Holocene. Magnetic susceptibility and
geochemical proxies obtained from the high mountain lake record of Laguna
Hondera evidence humid conditions during the early Holocene, while a trend
towards more arid conditions is recognized since ∼7000 cal yr BP, with enhanced
Saharan eolian dust deposition until the present. This trend
towards enhanced arid conditions was modulated by millennial-scale climate
variability. Relative humid conditions occurred during the Iberian Roman
Humid Period (2600–1450 cal yr BP) and predominantly arid conditions
occurred during the Dark Ages and the Medieval Climate Anomaly (1450–650 cal yr BP). The Little Ice Age (650–150 cal yr BP) is characterized in the
Laguna Hondera record by an increase in runoff and a minimum in eolian input. In addition,
we further suggest that human impact in the area is noticed through the
record of Olea cultivation, Pinus reforestation and Pb pollution during the
Industrial Period (150 cal yr BP–present). Furthermore, we estimated that
the correlation between Zr and Ca concentrations stands for Saharan dust
input to the Sierra Nevada lake records. These assumptions support that
present-day biochemical observations, pointing to eolian input as the main
inorganic nutrient source for oligotrophic mountain lakes, are comparable to
the past record of eolian supply to these high-altitude lakes.
ESD Ideas: The stochastic climate model shows that underestimated Holocene trends and variability represent two sides of the same coin
Authors: Lohmann Gerrit
Published: November 2018

Abstract. Holocene sea surface temperature trends and variability are underestimated in
models compared to paleoclimate data.
The idea is presented that the local trends and variability are related, which is elaborated in a conceptual framework of the stochastic climate model.
The relation is a consequence of the fluctuation–dissipation theorem, connecting the linear response
of a system to its statistical fluctuations.
Consequently, the spectrum can be used to estimate the timescale-dependent climate response.
The non-normality in the propagation operator introduces enhanced long-term variability
related to nonequilibrium and/or Earth system sensitivity. The simple model can guide us to analyze comprehensive models' behavior.
Global phosphorus recovery from wastewater for agricultural reuse

Published: November 2018

Abstract. Phosphorus is a nutrient necessary for the development of crops and is thus
commonly applied as fertilizer to sustain agricultural production. It occurs
naturally, in indefinite quantities of uncertain quality in phosphate rock
formations, but also accumulates in urban and livestock wastewater wherefrom
it is often lost as a pollutant. Recovering phosphorus from wastewater,
however, is feasible through struvite crystallization technologies and has
the potential to reduce phosphorus pollution of the environment as well as
lower the agricultural demand for artificial P fertilizers. In this study, we
developed a model to assess the global potential of P fertilizer recovery
from wastewater and to visualize its trade at sub-national resolution.
Results show that humans discharge a maximum of 3.7 Mt P into wastewater,
thereby potentially satisfying 20 % of the global fertilizer demand.
Provided 2015 market dynamics, however, the model determines that only
4 % of this discharge is technologically and economically recoverable in
a market that offers cheap rock phosphate products also. The results of this
study demonstrate that in the current economic context, phosphorus recovery
from wastewater offers only a small contribution to resolving global
phosphorus issues. Nevertheless, this recovery offers many wastewater
treatment facilities the opportunity to contribute to creating sustainable
communities and protecting the environment locally, while reducing their own
operational costs.
