Evolution of squall line variability and error growth in an ensemble of large eddy simulations
Authors: Groot Edward , Tost Holger
Published: January 2023

Abstract. A chain of processes is identified that regulates much of the spread in an ensemble of squall lines in large eddy simulations with tight initial conditions. Patterns of gravity wave propagation de-correlate and restructure the initial condition spread until a second phase of convective initiation is taking place, i.e. after 30 min of simulation time. Subsequently, variability in this convective initiation and mass overturn is associated with differences in cold pool propagation within the ensemble (propagation at 2–4 m s−1. An ensemble sensitivity analysis reveals that anomalies in squall-line-relative flow with respect to the ensemble mean are also associated with the secondary convective initiation. Downdraughts are fed with extra air by a convergence zone on the rearward flank of the updraughts. An analysis of difference growth within the ensemble shows that a substantial proportion of variability is explained by cold pool propagation contrasts during this stage (30–80 min), which is partly removed when a feature-relative perspective is taken. The patterns of coherent variability exist on the timescale of an hour and dissipate subsequently (80–100 min).
Spectral replacement using machine learning methods for continuous mapping of the Geostationary Environment Monitoring Spectrometer (GEMS)
Authors: Lee Yeeun , Ahn Myoung-Hwan , Kang Mina , Eo Mijin
Published: January 2023

Abstract. Earth radiances in the form of hyperspectral measurements
contain useful information on atmospheric constituents and aerosol
properties. The Geostationary Environment Monitoring Spectrometer (GEMS) is
an environmental sensor measuring such hyperspectral data in the ultraviolet and visible spectral range over the Asia–Pacific region. After completion of the in-orbit test of GEMS in October 2020, bad pixels are found as one of remaining calibration issues resulting in obvious spatial gaps in the measured radiances as well as retrieved properties. To solve the fundamental cause of the issue, this study takes an approach reproducing the defective
spectra with machine learning models using artificial neural network (ANN)
and multivariate linear regression (Linear). Here the models are trained
with defect-free measurements of GEMS after dimensionality reduction with
principal component analysis (PCA). Results show that the PCA-Linear model
has small reproduction errors for a narrower spectral gap and is less
vulnerable to outliers with an error of 0.5 %–5 %. On the other hand, the PCA-ANN model shows better results emulating strong non-linear relations with an error of about 5 % except for the shorter wavelengths around 300 nm. It is demonstrated that dominant spectral patterns can be successfully
reproduced with the models within the level of radiometric calibration
accuracy of GEMS, but a limitation remains when it comes to finer spectral
features. When applying the reproduced spectra to retrieval processes of
cloud and ozone, cloud centroid pressure shows an error of around 1 %, while total ozone column density shows relatively higher variance. As an
initial step reproducing spectral patterns for bad pixels, the current study provides the potential and limitations of machine learning methods to
improve hyperspectral measurements from the geostationary orbit.
Spawner weight and ocean temperature drive Allee effect dynamics in Atlantic cod, Gadus Morhua: inherent and emergent density regulation
Authors: Winter Anna-Marie , Vasilyeva Nadezda , Vladimirov Artem
Published: January 2023

Abstract. Stocks of Atlantic cod, Gadus Morhua, show diverse recovery responses when fishing pressure is relieved. The expected outcome of reduced fishing pressure is that the population regains its size. However, there are also cod stocks that seem to be locked in a state of low abundance from which population growth does not, or only slowly, occur. A plausible explanation for this phenomenon can be provided by the Allee effect, which takes place when recruitment per capita is positively related to population density or abundance. However, because of methodological limitations and data constraints, such a phenomenon is often perceived as being rare or non-existent in marine fish. In this study, we used time-series of 17 Atlantic cod stocks to fit a family of population equations that consider the abundance of spawners, their body weight as well as sea water temperature as independent components of recruitment. The developed stock-recruitment function disentangles the effects of spawner abundance, spawner weight and temperature on recruitment dynamics and captures the diversity of density dependencies (compensation, Allee effect) of the recruitment production in Atlantic cod. The results show for 13 cod stocks an inherent, spawner abundance related Allee effect. Allee effect strength, i.e. the relative change between maximum and minimum recruitment per capita at low abundance, was increased when recruitment production was suppressed by unfavorable changes in water temperature and/or in spawner weight. The latter can be a concomitant of heavy fishing or a result of temperature related altered body growth. Allee effect strength was decreased when spawner weight and/or temperature elevated recruitment production. We show how anthropogenic stress can increase the risk of Allee effects in stocks where ocean temperature and/or spawner weight had been beneficial in the past, but are likely to “unmask” and strengthen an inherent Allee effect under future conditions.

Abstract. Waterlogged archaeological wood (WAW) is a rare and precious organic material that can hold outstanding cultural values. In order to protect WAW for the next generations, this material must be accurately characterized to set its proper conservation, storage and exhibition conditions in museum environments. In this study, the mineral content found in WAW retrieved in a volcanic lake, was investigated by analysing wood ash through scanning electron microscopy coupled with energy dispersion spectroscopy (SEM-EDS). This micro-destructive approach was coupled with morphological studies carried out through optical microscopy. SEM-EDS was also performed on the WAW and on the surrounding sediment, to study the possible correlation between the mineral composition and the wood degradation state. The analysis revealed that calcium was the most abundant element in all poles with weight percentages ranging between 24 % and 42 %. This element was more represented in heartwood (HW) than sapwood (SW). In Sapwood the second most abundant element was arsenic. Sulphur, iron, and potassium were also present in all the analysed samples. Arsenic was detected also in the sediments; it was particularly concentrated in the samples taken near archaeological wood. The presence of this element can be linked to the volcanic origin of the lake, and its high concentration points to bioaccumulation processes induced by bacteria (erosion bacteria and sulphate-reducing bacteria) and biochemical processes favouring precipitation of insoluble compounds. The present work is the first investigation on mineral content in archaeological wood establishing a possible correlation with the surrounding volcanic lake sediments.
Technical note: A software framework for calculating compositionally dependent in situ 14C production rates
Authors: Koester Alexandria J. , Lifton Nathaniel A.
Published: January 2023

Abstract. Over the last 30 years, in situ cosmogenic nuclides (CNs) have revolutionized
surficial processes and Quaternary geologic studies. Commonly measured CNs
extracted from common mineral quartz have long half-lives (e.g.,
10Be, 26Al) and have been applied over timescales from a few
hundred years to millions of years. However, their long half-lives also
render them largely insensitive to complex histories of burial and exposure of
less than ca. 100 kyr. On the other hand, in situ cosmogenic 14C (in situ 14C) is
also produced in quartz, yet its 5.7 kyr half-life renders it very sensitive
to complex exposure histories during the last ∼25 ka, a
particularly unique and powerful tool when analyzed in concert with
long-lived nuclides. In situ 14C measurements are currently limited to
relatively coarse-grained (typically sand-sized or larger, crushed or sieved to
sand) quartz-bearing rock types, but while such rocks are common, they are
not ubiquitous. The ability to extract and interpret in situ 14C from
quartz-poor and fine-grained rocks would thus open its unique applications
to a broader array of landscape elements and environments. As a first step toward this goal, a robust means of interpreting in situ 14C
concentrations derived from rocks and minerals spanning wider compositional
and textural ranges will be crucial. We have thus developed a
MATLAB®-based software framework to quantify
spallogenic production of in situ 14C from a broad range of silicate rock and
mineral compositions, including rocks too fine grained to achieve pure
quartz separates. As expected from prior work, production from oxygen
dominates the overall in situ 14C signal, accounting for >90 %
of production for common silicate minerals and six different rock types at
sea level and high latitudes (SLHL). This work confirms that Si, Al, and Mg
are important targets but also predicts greater production from Na than
from those elements. The compositionally dependent production rates for rock
and mineral compositions investigated here are typically lower than that of
quartz, although that predicted for albite is comparable to quartz,
reflecting the significance of production from Na. Predicted production
rates drop as compositions become more mafic (particularly Fe-rich). This framework should thus be a useful tool in efforts to broaden the utility of
in situ 14C to quartz-poor and fine-grained rock types, but future
improvements in measured and modeled excitation functions would be
beneficial.
A perspective for magic angle spinning above 250 kHz – OptiMAS
Authors: Korvink Jan
Published: January 2023

Abstract. Magic angle spinning averages out the dipolar coupling among spins in rigid solids, as well as other sources of magnetic inhomogeneity, leading to sideband suppression. To achieve line widths close to that achievable for the liquid state, it has been postulated that 250 kHz rotation frequencies have to be exceeded. Here we explore a perspective for a research project to achieve this goal.
On the calculation of smoothing kernels for seismic parameter spatial mapping: methodology and examples
Authors: Montiel-López David , Molina Sergio , Galiana-Merino Juan José , Gómez Igor
Published: January 2023

Abstract. Spatial mapping is one of the most useful methods to display information about the seismic parameters of a certain area. As in b-value time series, there is a certain arbitrariness regarding the function selected as smoothing kernel (which plays the same role as the window size in time series). We propose a new method for the calculation of the smoothing kernel as well as its parameters. Instead of using the spatial cell-event distance we study the distance between events (event-event distance) in order to calculate the smoothing function, as this distance distribution gives information about the event distribution and the seismic sources. We examine three different scenarios: two shallow seismicity settings and one deep seismicity catalog. The first one, Italy, allows calibration and showcasing of the method. The other two catalogs: the Lorca region (Spain) and Vrancea County (Romania) are examples of different function fits and data treatment. For these two scenarios, the prior to earthquake and after earthquake b-value maps depict tectonic stress changes related to the seismic settings (stress relief in Lorca and stress build-up zone shifting in Vrancea). This technique could enable operational earthquake forecasting (OEF) and tectonic source profiling given enough data in the time span considered.

Abstract. Subglacial lakes form beneath ice sheets and ice caps if water is available, and if bedrock and surface topography are able to retain the water. On a regional scale, the lakes modulate the timing and rate of freshwater flow through the subglacial system to the ocean by acting as reservoirs. More than one hundred hydrologically active subglacial lakes, that drain and recharge periodically, have been documented under the Antarctic ice sheet, while only a handful of active lakes have been identified in Greenland. The small size of the Greenlandic subglacial lakes puts additional demands on mapping capabilitie aiming to resolve the evolving surface topography in sufficient detail to record their temporal behavior. Here, we explore the potential for combining data from CryoSat-2, TanDEM-X, and ArcticDEM to document the evolution of four active subglacial lake sites in Greenland. The inclusion of the new data sources provides important information on lake activity, documenting that the ice surface collapse basin on Flade Isblink ice cap was 50 % (30 meters) deeper than previously recorded. We also present evidence of a new active subglacial lake in Southwest Greenland, which shows signs of being hydrologically connected to another subglacial lake in that region. These findings show how improving the measurement capabilities of subglacial lakes, improves our current understanding and knowledge of the subglacial water system and its connection to surface hydrology.
The role of Rossby waves in polar weather and climate

Published: January 2023

Abstract. Recent Arctic warming has fuelled interest in the weather and climate of the polar regions and how this interacts with lower latitudes. Several interesting theories of polar-midlatitude linkages involve Rossby wave propagation as a key process even though the meridional gradient in planetary vorticity, crucial for these waves, is weak at high latitudes. Here we review some basic theory and suggest that Rossby waves can indeed explain some features of polar variability, especially when relative vorticity gradients are present. We suggest that large-scale polar flow can be conceptualised as a mix of geostrophic turbulence and Rossby wave propagation, as in the midlatitudes, but with the balance tipped further in favour of turbulent flow. Hence, isolated vortices often dominate but some wavelike features remain. As an example, quasi-stationary or weakly westward-propagating subpolar anomalies emerge from statistical analysis of observed data, and these are consistent with some role for wave propagation. The noted persistence of polar cyclones and anticyclones is attributed in part to the weakened effects of wave dispersion, the mechanism responsible for the decay of midlatitude anomalies in downstream development. We also suggest that the vortex-dominated nature of polar dynamics encourages the emergence of annular mode structures in principal component analyses of extratropical circulation. Finally, we consider how Rossby waves may be triggered from high latitudes. The linear mechanisms known to balance localised heating at lower latitudes are shown to be less efficient in the polar regions. Instead, we suggest the direct response to sea ice loss often manifests as a heat low, with radiative cooling balancing the heating. If the relative vorticity gradient is favourable this does have the potential to trigger a Rossby wave response, although this will often be weak compared to waves forced from lower latitudes.
Plant clustering generates negative plant–soil feedback without changing the spatial distribution of soil fauna
Authors: Zhang Peihua , Bonte Dries , De Deyn Gerlinde , Vandegehuchte Martijn L.
Published: January 2023

Abstract. The spatial distribution of resources affects ecological processes at all
levels of biological organization. However, it remains to be tested how the
spatial configuration of belowground resources affects the community
dynamics of soil organisms and resulting plant–soil feedbacks. We used Agrostis stolonifera plants in different spatial configurations in
mesocosms to study the dispersal patterns of soil nematodes and rotifers.
Plant–soil feedbacks were later assessed by re-sowing the mesocosms with
Lolium perenne and Plantago lanceolata after removing all the initial A. stolonifera plants from the mesocosms. Bacterial-feeding nematodes and
rotifers spread fast, whereas plant-feeding nematodes barely dispersed from
the release sites. These spread patterns of nematodes and rotifers depended
on the life-history traits and not on the spatial pattern of the plants.
However, more clustered plants developed a higher total biomass and caused a reduced growth of the subsequent vegetation. Our results demonstrate that the mere spatial pattern of a single plant
species can alter the strength of plant–soil feedbacks. This has important
implications for understanding the impact of planting or replanting schemes
and other changes in the spatial configuration of plants on long-term
vegetation development and succession.
Returning to the Point of Entanglement: Sexual Difference and Creolization
Authors: Kim Ruthanne C.
Published: January 2023

In this essay, I suggest an entangled analysis of sexual difference theory via Luce Irigaray and creolization via Édouard Glissant. I argue that these two distinct discourses share a critical stance against Western sameness and assimilation into a closed metaphysical system. However, each is born of particular historical socio-political struggles that should not be collapsed. I bring them together to demonstrate that their claims are productively entangled and that a critical re-reading of melancholia can unite readers to locate sources of sexual-racial-colonial violence in disparate locations and epochs, holding collective memory and acting beyond critique. Relying on Francoise Vergès’s account of métissage and anamnesis, I will suggest that Antillean geographical vantages reveal complexities of racial and colonial relation to one’s mother, the state, and the sea. By interrogating psychoanalytic and linguistic claims, I forward a South-South circulation of coordinated but distinctive political reimaginations that challenge static notions of race, gender, and sexual difference.

Neste artigo propusemos uma reflexão acerca da categoria teórica práxis, a partir do seguinte questionamento: como é possível pensar a construção de uma práxis emancipatória no atual contexto brasileiro? Para examinar essa questão, situamos o conceito de fatalismo histórico como possibilidade de compreender como as relações de forças se constituem no atual momento, diante da ameaça social advinda de dois agentes: o atual governo neoconservador brasileiro e o vírus da covid-19, gerador de uma pandemia. Compreendemos que esses agentes contribuem à intensificação da ofensiva neoliberal, que evidencia as contradições estruturais da ordem do capital. Estabelecemos a categoria práxis como expressão do processo de consciência crítica de sujeitos, o qual institui um movimento necessário à mudança social, a partir de uma concepção histórica da realidade.

Description d’un squelette complet de Metailurus (Felidae, Carnivora, Mammalia) du Miocène supérieur de Bulgarie
Authors: Kovachev Dimitar
Published: January 2023

A new species of Felidae, Metailurus anceps, has been found in the Upper Miocene outcrops at Hadjidimovo, SW Bulgaria. The material consists of an almost complete skeleton (133 parts) that is unique in preservation and belongs to a young-adult specimen. The morphological features of the taxon point at intermediate positions between Felinae and Machairodontinae. The most similar species is Metailurus major Zdansky, 1924. However, the specimen from Hadjidimovo differs from the latter by a more pronounced simplitication of the premolars, the zygomatic processus is strongly shortened, the mastoid processus is better developed, and the processes jugalis and frontalis are shorter and pointed. There is a clear angle between the anterior part of the symphysis and the horizontal branch of the mandible, too.
Two spectral calculations and their applications to PDE analysis of incompressible fluid flows
Authors: Sverak Vladimir
Published: January 2023

We will discuss two problems for the incompressible Navier-Stokes equations whose solutions can be obtained via computations of suitable spectra. The first concerns the uniqueness of the Leray-Hopf solutions, where an important spectral computation still needs computer assistance. The second concerns the long-distance behavior of the steady 3d solutions in exterior domains. Here the relevant spectral computations can be done by the traditional 'paper and pencil' methods and one can obtain certain higher-order asymptotics for the solutions that may be somewhat unexpected. The talk is based on joint works with Hao Jia and Julien Guillod.

Published: January 2023

Objective: To understand healthcare professionals’ perception of best practices in maternal and child health. Materials and methods: This qualitative exploratory-descriptive study was conducted between December 2020 and March 2021. The study corpus consisted of 23 healthcare professionals from southern Brazil. Data were collected using a semi-structured script and coded based on Minayo’s thematic content analysis proposed. Results: Data analysis enabled the delimitation of two thematic categories: “best practices in maternal and child health: from idealization to accomplishment” and “strategies to qualify the maternal and child healthcare network.” Conclusions: Healthcare professionals recognize the relevance of best practices in maternal and child health, although this process must be expanded and consolidated. Continuing education, hospitality, ambiance, improved access, and the professional-user connection stand out among the qualifying strategies.

La colisión de derechos en la dogmática jurídico-penal
Authors: Fernández Perales Francisco
Published: January 2023

Las (aparentes) colisiones de derechos que resultan relevantes para el Derecho penal se han venido resolviendo por doctrina y jurisprudencia con arreglo al método ponderativo. La ausencia de trabajos doctrinales que pongan en cuestión esta práctica, sin embargo, contrasta con la intensidad de la crítica al método ponderativo y a la teoría de los derechos que éste toma como premisa en el ámbito de la Filosofía del Derecho. En el presente trabajo se parte de la denominada teoría especificacionista de los derechos, contrapuesta a la infraccionista (a la que se encuentra unida el método ponderativo), desde la que se propone una comprensión de la justificación por el ejercicio de un derecho distinta a la mayoritaria. Asimismo, se aboga por tomar dicha teoría como punto de partida para la solución de los casos de exceso en el ejercicio de un derecho, respecto de los que se plantea la posibilidad de recuperar la categoría de la exclusión del injusto penal.

Published: January 2023

Nowadays Air Conditioner (AC) has become a more important appliance in our life. Gas leakage, blockage in the evaporator and compressor coil, pipelines as well as dust in the air filters, are the major reasons behind AC explosion. Many people have been injured over the years due to AC blasts. In this paper a system is developed that uses sensor technology and smart devices to reduce AC blast. As a result, pipeline leaks or blockage fault detection system is planned and constructed using MQ-02, TTC 103, optical dust sensors for gas detection, temperature detection and for detecting dust density respectively. Also bacteria can be detected through MQ-3 gas sensor as it combines with AC refrigerant and produces ethanol. This system is also digitally connected to smart devices (cellphones) and a control device (RM MINI 3) so that user can receive a detection notification at any time and operate AC from any location. By implementing these sensors, the initial target was achieved. The work is low cost and environment friendly.

Pioneers and landmarks in intelligence testingChallenging the hierarchical model of intelligence
Authors: McCredie Hugh
Published: January 2023

Key digested message

So far in this series we have tracked the view that factoring known measures of intelligence leads to a hierarchical model with general intelligence, g, transcending successively narrower abilities. However, most admit that the intellectual measures on which such factor analysis was based do not cover the full bandwidth of intelligent behaviour.

The next two articles (articles 9 and 10 in the series) will look at authors who challenged this hierarchical model. The first, Robert Sternberg, extended the existing body of understanding in three different directions. The second, Howard Gardner, featured in the next article, offered an entirely non-hierarchical alternative model of intelligences.

Ethnic Matching in Counselling: How important is it to Ethnically Match Clients and Counsellors?*
Authors: Alladin Waseem J.
Published: January 2023

The short answer to this complex question is “It depends”. It may help to consider the rationale behind ethnic matching. When counsellor and client share the same cultural background, empathic understanding and self-disclosure are more easily facilitated. However, most counsellors and counsellor trainers are white, middle-class people whose values and communication styles may differ from those of ethnic minority clients especially those of lower socio-economic status. Thus white counsellors may unwittingly engage in cultural oppression by imposing Western values on ethnic minority clients. Further, ethnic minority clients, because of a historical exposure to, and current experiences of, racism may have a damaged ethnic or racial identity which would hinder the development of a therapeutic alliance with a white counsellor. Thus understanding the client’s ethnic or racial identity development is important in cross-cultural counselling.
