Comprehensive detection of analytes in large chromatographic datasets by coupling factor analysis with a decision tree
Authors: Kim Sungwoo , Lerner Brian M. , Sueper Donna T. , Isaacman-VanWertz Gabriel
Published: September 2022

Abstract. Environmental samples typically contain hundreds or thousands of unique organic compounds, and even minor components may provide valuable insight
into their sources and transformations. To understand atmospheric processes, individual components are frequently identified and quantified using
gas chromatography–mass spectrometry. However, due to the complexity and frequently variable nature of such data, data reduction is a significant
bottleneck in analysis. Consequently, only a subset of known analytes is often reported for a dataset, and large amounts of potentially useful data
are discarded. We present an automated approach of cataloging and potentially identifying all analytes in a large chromatographic dataset and
demonstrate the utility of our approach in an analysis of ambient aerosols. We use a coupled factor analysis–decision tree approach to deconvolute
peaks and comprehensively catalog nearly all analytes in a dataset. Positive matrix factorization (PMF) of small subsections of multiple
chromatograms is applied to extract factors that represent chromatographic profiles and mass spectra of potential analytes, in which peaks are
detected. A decision tree based on peak parameters (e.g., location, width, and height), relative ratios of those parameters, peak shape, noise,
retention time, and mass spectrum is applied to discard erroneous peaks and combine peaks determined to represent the same analyte. With our
approach, all analytes within the small section of the chromatogram are cataloged, and the process is repeated for overlapping sections across the
chromatogram, generating a complete list of the retention times and estimated mass spectra of all peaks in a dataset. We validate this approach
using samples of known compounds and demonstrate the separation of poorly resolved peaks with similar mass spectra and the resolution of peaks that
appear in only a fraction of chromatograms. As a case study, this method is applied to a complex real-world dataset of the composition of
atmospheric particles, in which more than 1100 unique chromatographic peaks are resolved, and the corresponding peak information along with mass spectra are cataloged.
Dispersal of bacteria and stimulation of permafrost decomposition by Collembola
Authors: Monteux Sylvain , Mariën Janine , Krab Eveline J.
Published: September 2022

Abstract. Contrary to most soils, permafrost soils have the
atypical feature of being almost entirely deprived of soil fauna. Abiotic
constraints on the fate of permafrost carbon after thawing are increasingly
understood, but biotic constraints remain scarcely investigated. Incubation
studies, essential to estimate effects of permafrost thaw on carbon cycling,
typically measure the consequences of permafrost thaw in isolation from the
topsoil and thus do not account for the effects of altered biotic
interactions because of e.g. colonization by soil fauna. Microarthropods
facilitate the dispersal of microorganisms in soil, both on their cuticle
(ectozoochory) and through their digestive tract (endozoochory), which may
be particularly important in permafrost soils, considering that microbial
community composition can strongly constrain permafrost biogeochemical
processes. Here we tested how a model species of microarthropod (the Collembola
Folsomia candida) affected aerobic CO2 production of permafrost soil over a 25 d
incubation. By using Collembola stock cultures grown on permafrost soil or
on an arctic topsoil, we aimed to assess the potential for endo- and
ectozoochory of soil bacteria, while cultures grown on gypsum and sprayed
with soil suspensions would allow the observation of only ectozoochory. The presence of Collembola introduced bacterial amplicon sequence variants (ASVs) absent in the
no-Collembola control, regardless of their microbiome manipulation, when
considering presence–absence metrics (unweighted UniFrac metrics), which
resulted in increased species richness. However, these introduced ASVs did
not induce changes in bacterial community composition as a whole (accounting
for relative abundances, weighted UniFrac), which might only become
detectable in the longer term. CO2 production was increased by 25.85 % in the presence of
Collembola, about half of which could be attributed to Collembola
respiration based on respiration rates measured in the absence of soil. We
argue that the rest of the CO2 being respired can be considered a
priming effect of the presence of Collembola, i.e. a stimulation of
permafrost CO2 production in the presence of active microarthropod
decomposers. Overall, our findings underline the importance of biotic
interactions in permafrost biogeochemical processes and the need to explore
the additive or interactive effects of other soil food web groups of which
permafrost soils are deprived.

Published: September 2022

Abstract. European Space Agency’s (ESA) Aeolus satellite mission is the first Doppler wind lidar in space, operating in orbit for more than three years since August 2018 and providing global wind profiling throughout the entire troposphere and the lower stratosphere. The Observatoire de Haute Provence (OHP) in southern France and the Observatoire de Physique de l’Atmosphère à La Réunion (OPAR) are equipped with ground-based Doppler Rayleigh-Mie lidars, which operate on similar principles to the Aeolus lidar, and are among essential instruments within ESA Aeolus Cal/Val program. This study presents the validation results of the L2B Rayleigh-clear HLOS winds from September 2018 to January 2022. The point-by-point validation exercise relies on a series of validation campaigns at both observatories: AboVE (Aeolus Validation Experiment) that were held in September 2019 and June 2021 at OPAR, and in January 2019 and December 2021 at OHP. The campaigns involved time-coordinated lidar acquisitions and radiosonde ascents collocated with the nearest Aeolus overpasses. During AboVE-2, Aeolus was operated in a campaign mode with an extended range bin setting allowing inter-comparisons up to 28.7 km. We show that this setting suffers from larger random error in the uppermost bins, exceeding the estimated error, due to lack of backscatter at high altitudes. To evaluate the long-term evolution in Aeolus wind product quality, twice-daily routine Météo-France radiosondes and regular lidar observations were used at both sites. This study evaluates the long-term evolution of the satellite performance along with punctual collocation analyses. On average, we find a systematic error (bias) of −0.92 ms-1 and −0.79 ms-1 and a random error (scaled MAD) of 6.49 ms-1 and 5.37 ms-1 for lidar and radiosondes, respectively.
A non-extensive approach to probabilistic seismic hazard analysis
Authors: Motaghed Sasan , Khazaee Mozhgan , Eftekhari Nasrollah , Mohammadi Mohammad
Published: September 2022

Abstract. We modify the probabilistic seismic hazard analysis (PSHA) formulation by replacing the Gutenberg-Richter power law with the SCP non-extensive model for earthquake size distribution and call it NEPSHA. SCP claimed to better model the regional seismicity than the classical models. The proposed method (NEPSHA) is implemented in the Tehran region, and the results are compared with the classic PSHA method. The hazard curves show that NEPSHA gives a higher hazard, especially in the range of practical return periods. The uniform hazard spectra of NEPSHA provide more spectral accelerations, especially for the medium height buildings, which are the most common urban structures.
Assessing the role of thermal disequilibrium in the evolution of the lithosphere–asthenosphere boundary: an idealized model of heat exchange during channelized melt transport
Authors: Roy Mousumi
Published: September 2022

Abstract. This study explores how the continental lithospheric mantle (CLM) may be heated during channelized melt transport when there is thermal disequilibrium between (melt-rich) channels and surrounding (melt-poor) regions.
Specifically, I explore the role of disequilibrium heat exchange in weakening and destabilizing the lithosphere from beneath as melts infiltrate into the lithosphere–asthenosphere boundary (LAB) in intraplate continental settings.
During equilibration, hotter-than-ambient melts would be expected to heat the surrounding CLM, but we lack an understanding of the expected spatiotemporal scales and how these depend on channel geometries, infiltration duration, and transport rates.
This study assesses the role of heat exchange between migrating material in melt-rich channels and their surroundings in the limit where advective effects are larger than diffusive heat transfer (Péclet numbers > 10).
I utilize a 1D advection–diffusion model that includes thermal exchange between melt-rich channels and the surrounding melt-poor region, parameterized by the volume fraction of channels (ϕ), average relative velocity (vchannel) between material inside and outside of channels, channel spacing (d), and timescale of episodic or repeated melt infiltration (τ).
The results suggest the following: (1) during episodic infiltration of hotter-than-ambient melt, a steady-state thermal reworking zone (TRZ) associated with spatiotemporally varying disequilibrium heat exchange forms at the LAB.
(2) The TRZ grows by the transient migration of a disequilibrium-heating front at a material-dependent velocity, reaching a maximum steady-state width δ proportional to ϕvchannel(τ/d)n, where n≈2 for periodic thermal perturbations and n≈1 for a single finite-duration thermal pulse.
For geologically reasonable model parameters, the spatiotemporal scales associated with establishment of the TRZ are comparable with those inferred for the migration of the LAB based on geologic observations within continental intra-plate settings, such as the western US.
The results of this study suggest that, for channelized transport speeds of vchannel=1 m yr−1, channel spacings d≈102 m, and timescales of episodic melt infiltration τ≈101 kyr, the steady-state width of the TRZ in the lowermost CLM is ≈10 km.
(3) Within the TRZ, disequilibrium heat exchange may contribute ≈10-5 W m−3 to the LAB heat budget.
How well does digital soil mapping represent soil geography? An investigation from the USA
Authors: Rossiter David G. , Poggio Laura , Beaudette Dylan , Libohova Zamir
Published: September 2022

Abstract. We present methods to evaluate the spatial patterns of the geographic distribution of soil properties in the USA, as shown in gridded maps produced by digital soil mapping (DSM) at global (SoilGrids v2), national (Soil Properties and Class 100 m Grids of the USA), and regional (POLARIS soil properties) scales and compare them to spatial patterns known from detailed field surveys (gNATSGO and gSSURGO). The methods are illustrated with an example, i.e. topsoil pH for an area in central New York state. A companion report examines other areas, soil properties, and depth intervals. A set of R Markdown scripts is referenced so that readers can apply the analysis for areas of their interest. For the test case, we discover and discuss substantial discrepancies between DSM products and large differences between the DSM products and legacy field surveys. These differences are in whole-map statistics, visually identifiable landscape features, level of detail, range and strength of spatial autocorrelation, landscape metrics (Shannon diversity and evenness, shape, aggregation, mean fractal dimension, and co-occurrence vectors), and spatial patterns of property maps classified by histogram equalization. Histograms and variogram analysis revealed the smoothing effect of machine learning models. Property class maps made by histogram equalization were substantially different, but there was no consistent trend in their landscape metrics. The model using only national points and covariates was not substantially different from the global model and, in some cases, introduced artefacts from a lithology covariate. Uncertainty (5 %–95 % confidence intervals) provided by SoilGrids and POLARIS were unrealistically wide compared to gNATSGO/gSSURGO low and high estimated values and show substantially different spatial patterns. We discuss the potential use of the DSM products as a (partial) replacement for field-based soil surveys. There is no substitute for actually examining and interpreting the soil–landscape relation, but despite the issues revealed in this study, DSM can be an important aid to the soil surveyor.
Investigating Horizontal Axis Wind Turbine Aerodynamics Using Cascade Flows
Authors: Golmirzaee Narges , Wood David H.
Published: September 2022

Abstract. The simplest aerodynamic model of horizontal-axis wind turbines is blade element-momentum theory. The blades are divided radially into small elements which are assumed to behave as airfoils when determining the lift and drag. Since all blades have neighbours, a more accurate two-dimensional representation is an infinite cascade of identical, equispaced lifting bodies. In this study, cascades of airfoils1 at spacings and pitch angles typical of wind turbine applications, are analyzed using the conventional and impulse forms of the force equations for two-dimensional, steady, incompressible flow. The flow at a Reynolds number of 6×106 through cascades of NACA 0012 airfoils was simulated using OpenFOAM software. The results of the force equations agree well (less than 1 % error) with the body forces determined directly from OpenFOAM for four spacing ratios. Examining the terms of these equations reveals the importance of the circulation, the viscous drag, and the displacement effect of the body's wake due to its finite width. We focus on the "wake vorticity" term, which is ignored in blade element-momentum analysis. At a pitch angle of 90°, this term balances the viscous drag when the angle of attack is zero. At zero pitch, which models the outer region of a wind turbine blade at high tip speed ratio, the term can account for 27 % of the axial thrust when angle of attack is about 4°. This condition represents the rotor entering the high thrust region after the maximum power point. A simple equation is proposed for the wake vorticity term that is suitable for incorporation in blade element-momentum analysis. The normal force equation, like the angular momentum equation for wind turbines, has no viscous term which forces the body drag to contribute to the circulation in the wake. It is shown that the airfoil assumption is conservative in that cascade elements always have higher lift:drag ratios than airfoils at the same angle of attack. An associated result is that separation occurs at higher angles of attack on a cascade element compared to an airfoil.

Authors: Stepanyan S.A. , Khachatryan M.V. , Pipoyan D.A.
Published: September 2022

Mining, including copper (Cu) production, is one of the primary economic activities in Armenia. Besides having an adverse environmental impact, it can lead to Cu accumulation in food, including honey. Considering the wide production and consumption of honey, this study aims to assess the dietary exposure of Cu through honey consumption in Yerevan, Armenia. Seventeen honey samples were included in the study. Food Frequency Questionnaire was used to evaluate honey consumption. While Cu contents exceed the Maximum Residue Level, dietary exposure estimates do not exceed the oral reference dose. Hence, the consumption of honey sold in Yerevan does not have the potential to
cause adverse health effects.

Authors: Pacara Copa Marina
Published: September 2022

Las diversas manifestaciones patológicas que se presentan en el pavimento flexible como ser las fisuras, deformación, ahuellamiento, desprendimientos, pérdida de las capas de la estructura,  agrietamiento (fatiga), baches y parches, etc., siendo las mencionadas las más conocidas por ser detectadas a simple vista; cada una de estas merecen un dedicado estudio siendo muchas las razones por las cuales se llegan a manifestar. Este trabajo se centró en analizar de manera superficial una fisura en el pavimento flexible con termografía infrarroja realizando un monitorio de 7 horas durante el día, desde las 11:00 hasta las 17:00. La fisura analizada pertenece a la calle vecinal Itos, de la zona sur de Cochabamba en la que se marcaron 6 puntos sobre la longitud de la fisura. Mediante el monitoreo de los 6 puntos se pudo observar y comprobar una tendencia ascendente relativamente  homogénea de la temperatura en los distintos puntos, siendo cada una diferente por la gravedad que visiblemente se percibió en toda la trayectoria de la fisura; también se observó una temperatura máxima y mínima que se concluye que muestran los puntos de fisura superficial y fisura critica (profunda) respectivamente. Siendo este un análisis superficial mediante la apreciación del ojo humano, versus los resultados de la termografía infrarroja, merece un estudio profundo y objetivo para ampliar, corroborar, descartar y corregir lo estudiado en este caso.

The purpose of this study was to determine the effect of ship worthiness and seafarers' skills on improving ship operational performance through minimum service standards. Some early indications found in the field, such as the low performance of ship maintenance by procedures, and the obstacles in implementing the ship maintenance plan due to the inefficiency of the ship's operating schedule. This study uses Path Analysis with Path Coefficients Sub Structure 1 and Sub Structure 2. The test method used for the direct effect is the regression method while the indirect effect is the Sobel test. The number of samples is 80 respondents from national shipping companies, from various types of ships, namely, crew boats, patrol boats, utility boats, supply vessels, and anchor handling towing supply. The results of the study indicate that there is a positive and significant effect of seaworthiness and seafarers' skills on increasing ship operational performance, directly or indirectly through minimum service standards. The minimum service standard variable can mediate the indirect effect of the seafarers' skill and ship worthiness variables on the operational performance of the ship. To meet the growing customer satisfaction as the consequences of tight competition, it is necessary to improve the quality of the fleet where durability, cleanliness of the fleet, and safety facilities in the fleet are expected to provide a high guarantee for safety.

Published: September 2022

This research aims to fill the research gap with empirical evidence that exists about the impact of blockchain and smart inventory systems on supply chain performance in the retail industry in the UAE. The proposed model is uniquely researched as no prior research explores the link between supply chain performances, blockchain, and smart inventory in prestigious academic journals. A quantitative technique with convenient cluster sampling is used. A descriptive, exploratory, causal and analytical design was applied—a sample size of 303 respondents was used for data analysis through regression and hypothesis with ANOVA. The findings revealed a significant positive impact of blockchain and smart inventory systems on SC performance. Limited construct-based research can be focused on more industries and constructs for future studies. There are numerous chances for businesses to leverage blockchain technology to their advantage over the competition, giving them the chance to strengthen their market position. Managers must carefully consider the qualities of their goods, services, and supply chains to ascertain whether they require or would sufficiently benefit from blockchain.

Clinical Results Following Conservative Management of Tarsal Tunnel Syndrome Compared With Surgical Treatment: A Systematic Review
Authors: Vij Neeraj , Kaley Heather N. , Robinson Christopher L. , Issa Peter P. , Kaye Alan D. , Viswanath Omar , Urits Ivan
Published: September 2022

Introduction

Posterior tarsal tunnel syndrome involves entrapment of the posterior tibial nerve as it travels in the groove posterior to the medial malleolus. Conventional wisdom dictates that patients with tarsal tunnel syndrome be treated with conservative treatment and medical management, with surgical options available for patients with refractory symptoms and good candidacy. Minimally invasive options for neuropathic entrapment syndromes have developed in recent years and may provide a therapeutic role in tarsal tunnel syndrome.

Objective

The present investigation provides a summary of the current state of knowledge on tarsal tunnel syndrome and a comparison between minimally invasive and surgical treatment options.

Methods

The literature search was performed in Mendeley. Search fields were varied until redundant. All articles were screened by title and abstract and a preliminary decision to include an article was made. A full-text screening was performed on the selected articles. Any question regarding the inclusion of an article was discussed by 3 authors until an agreement was reached.

Results

Most commonly tarsal tunnel syndrome is idiopathic. Other reported causes include post-traumatic, lipomas, cysts, ganglia, schwannomas, ganglia, varicose plantar veins, anatomic anomalies, and systematic inflammatory conditions. Several risk factors have been described including female gender, athletic participation, hypothyroidism, diabetes mellitus, systemic sclerosis, chronic renal failure, and hemodialysis use. A few recent studies demonstrate anatomic variants that have not previously been summarized. Three articles describe clinical outcomes after conservative treatment with acceptable results for first line treatment. Two primary articles report on the use of minimally invasive treatment for tarsal tunnel syndrome. Fourteen articles report on the clinical outcomes after surgical management.

Conclusion

Clinical understanding of tarsal tunnel syndrome has evolved significantly, particularly with regards to the pathoanatomy of the tarsal canal over the past twelve years. A few novel anatomic studies shed light on variants that can be helpful in diagnosis. Conservative management remains a good option that can resolve the symptoms of many patients. As more prospective cohorts and clinical trials are performed on minimally invasive options, pulsed radiofrequency and neuromodulation may evolve to play a larger role in the treatment of this condition. Currently, surgical treatment is only pursued in a very select group of patients with refractory symptoms that do not respond to medical or minimally invasive options. Surgical outcomes in the literature are good and current evidence is stronger than that for minimally invasive options.

Con el objeto de evaluar la utilización del suero rico en plaquetas (PRP), solo o combinado con otros activadores celulares, como son el cloruro de calcio y/o la trombina, sobre el proceso de cicatrización de la piel en conejos con heridas inducidas artíficamente, se llevó un experimento en la cual se utilizaron 10 unidades experimentales, a los cuales se les realizaron 3 heridas (incisiones quirúrgicas de 5 cm), una en la zona de la espalda entre T4 y T8, y dos en los omoplatos, las que fueron posteriormente tratadas con PRP como inductor de la cicatrización (T1), PRP + PRP con CaCl2 (T2) y PRP con Trombina (T3). Los efectos cicatrizantes de los 3 tratamientos fueron evaluados los días (d) 7 post-operación, mediante la evaluación macroscópica de la herida y, en el d 15 se realizó la evaluación del tejido, con la metodología de tinción tricromía de Masson. Los resultados consistieron en conseguir: tejido conectivo fibroso, presencia de fibroblasto, presencia de elementos mediadores de la inflamación, tales como neutrófilos, linfocitos e histocitos, presencia de neovascularización y la cicatrización completa; todo ellos codificados en una escala semicuantitativa donde se colocó 1 si el hallazgo fue leve, 2 de forma moderada y 3 completo. Los resultados obtenidos indicaron la no existencia de diferencia estadística (P<0,05) entre los 3 tratamientos aplicados, no obstante, todos ellos demostraron un avance efectivo en el proceso de cicatrización en la piel de los conejos, al demostrar un claro indicio de aceleración de los procesos de vascularización y la abundancia y proliferación de los fibroblastos desde el d 7, lo cual acorta el tiempo de sanación de las heridas, consolidando al PRP como una alternativa terapéutica en la reparación de tejidos.
