Changes in stability and jumps in Dansgaard–Oeschger events: a data analysis aided by the Kramers–Moyal equation
Authors: Rydin Gorjão Leonardo , Riechers Keno , Hassanibesheli Forough , Witthaut Dirk , Lind Pedro G. , Boers Niklas
Published: December 2021

Abstract. Dansgaard–Oeschger (DO) events are sudden climatic shifts from cold to substantially milder conditions in the arctic region that occurred during previous glacial intervals. They can be most clearly identified in paleoclimate records of δ18O and dust concentrations from Greenland ice cores, which serve as proxies for temperature and atmospheric circulation patterns, respectively. The existence of stadial (cold) and interstadial (milder) phases is typically attributed to a bistability of the North Atlantic climate system allowing for rapid transitions from the first to the latter and a more gentle yet still fairly abrupt reverse shift from the latter to the first. However, the underlying physical mechanisms causing these transitions remain debated. Here, we conduct a data-driven analysis of the Greenland temperature and atmospheric circulation proxies under the purview of stochastic processes. Based on the Kramers–Moyal equation we present a one-dimensional and two-dimensional derivation of the proxies' drift and diffusion terms, which unravels the features of the climate system's stability landscape. Our results show that: (1) in contrast to common assumptions, the δ18O proxy results from a monostable process, and transitions occur in the record only due to the coupling to other variables; (2) conditioned on δ18O the dust concentrations exhibit both mono and bistable states, transitioning between them via a double-fold bifurcation; (3) the δ18O record is discontinuous in nature, and mathematically requires an interpretation beyond the classical Langevin equation. These findings can help understand candidate mechanisms underlying these archetypal examples of abrupt climate changes.
A Dynamic Hierarchical Bayesian Approach for Forecasting Vegetation Condition
Authors: Salakpi Edward E. , Hurley Peter D. , Muthoka James M. , Bowell Andrew , Oliver Seb , Rowhani Pedram
Published: December 2021

Abstract. Agricultural drought, which occurs due to a significant reduction in the moisture required for vegetation growth, is the most complex amongst all drought categories. The onset of agriculture drought is slow and can occur over vast areas with varying spatial effects, differing in areas with a particular vegetation land cover or specific agro-ecological sub-regions. These spatial variations imply that monitoring and forecasting agricultural drought require complex models that consider the spatial variations in a given region of interest. Hierarchical Bayesian Models are suited for modelling such complex systems. Using partially pooled data with sub-groups that characterise spatial differences, these models can capture the sub-group variation while allowing flexibility and information sharing between these sub-groups. This paper's objective was to improve the accuracy and precision of agricultural drought forecast in spatially diverse regions with a Hierarchical Bayesian Model. Results showed that the Hierarchical Bayesian Model was better at capturing the variability for the different agro-ecological zones and vegetation land covers compared to a regular Bayesian Auto-Regression Distributed Lags model. The forecasted vegetation condition and associated drought probabilities were more accurate and precise with the Hierarchical Bayesian Model at 4 to 10 weeks lead times. Forecasts from the hierarchical model exhibited higher hit rates with a low probability of false alarms for drought events in semi-arid and arid zones. The Hierarchical Bayesian Model also showed good transferable forecast skills over counties not included in the training data.
Aerial observations of sea ice break-up by ship waves
Authors: Dumas-Lefebvre Elie , Dumont Dany
Published: December 2021

Abstract. We provide the first in situ observations of floe size distributions (FSD) resulting from wave-induced sea ice break-up. In order to obtain such data, an unmanned aerial vehicle was deployed from the Canadian Coast Guard Ship Amundsen as it sailed in the vicinity of large ice floes in Baffin Bay and in the St. Lawrence Estuary, Canada. When represented as probability density functions weighted by the surface of ice floes, the FSDs exhibit a strong modal shape which confirms the preferential size hypothesis debated in the scientific community. Both FSDs are compared to a flexural rigidity length scale, which depends on ice properties, and with the wavelength scale. This comparison tends to show that the maximal distance between cracks is preferentially dictated by sea ice thickness and elasticity rather than by the wavelength. Temporal analysis of one fracture event is also done. Results show that the break-up advances almost as fast as the wave energy and that waves responsible for the break-up propagate following the mass loading dispersion relation. Moreover, our experiments show that thicker ice can attenuate wave less than thinner ice. This method thus provides key information on the wave-induced FSD, clarifies theoretical aspects from the construction of the FSD to its implementation in models and brings new knowledge regarding the temporal evolution of sea ice break-up.
Turbulence statistics from three different nacelle lidars
Authors: Fu Wei , Peña Alfredo , Mann Jakob
Published: December 2021

Abstract. Atmospheric turbulence can be characterized by the Reynolds stress tensor, which consists of the second-order moments of the wind field components. Most of the commercial nacelle lidars cannot estimate all components of the Reynolds stress tensor due to their limited number of beams; most can estimate the along-wind velocity variance relatively well. Other components are however also important to understand the behavior of, e.g., the vertical wind profile and meandering of wakes. The SpinnerLidar, a research lidar with multiple beams and a very high sampling frequency, was deployed together with two commercial lidars in a forward-looking mode on the nacelle of a Vestas V52 turbine to scan the inflow. Here, we compare the lidar-derived turbulence estimates with those from a sonic anemometer using both numerical simulations and measurements from a nearby mast. We show that from these lidars, the SpinnerLidar is the only one able to retrieve all Reynolds stress components. For the two- and four-beam lidars, we study different methods to compute the along-wind velocity variance. By using the SpinnerLidar's Doppler spectra of the radial velocity, we can partly compensate for the lidar's probe volume averaging effect and thus reduce the systematic error of turbulence estimates. We find that the variances of the radial velocities estimated from the maximum of the Doppler spectrum are less affected by the lidar probe volume compared to those estimated from the median or the centroid of the Doppler spectrum.

Published: December 2021

The analysis of threats and dangers arising in the field of production and economy is carried out. The urgency of solving the problem of environmental safety of the individual and the state is substantiated. The influence of unfavorable factors on the ecological state of industrial and agricultural production zones is shown. The complex use of a source of х-ray and acoustic radiation, which increases the reliability of information and sensitivity to the detection of an emergency situation, is justified. An automated method of pipeline monitoring is proposed to detect defects and increase the resolution when they are detected.
Hegemonic Discourses of Métis Identity in British Columbia, Canada
Authors: Legault Gabrielle
Published: December 2021

Viewing Métis identity not as a natural, essential, or fixed phenomenon, but as an experience formed through internal and external factors, this article examines the mechanisms by which people residing in British Columbia identify as Métis. Through interviewing Métis Peoples and engaging in Critical Discourse Analysis (CDA) and Narrative Analysis (NA), this research demonstrates how Métis narratives centre on and replicate three hegemonic discourses based on racial mixedness, Métis cultural values, and Métis nationalism. The ‘Métis subject’ is then not an easily described coherent subject, but rather a co-constructed description based on transient identification with multiple and sometimes contradictory texts, which are themselves made meaningful through discourses. Understanding ‘Métis’ in this way allows for an exploration of the role of power in producing meanings of ‘Métis’ and how individuals, groups, and institutions can strategically mobilize particular meanings and resist definitions of Métis prescribed by Eurocentric perspectives embedded in colonial institutions.

Holocene fluctuations of the Black Sea level and human activities along the south Black Sea coast
Authors: Sinnyovsky Dimitar
Published: December 2021

Holocene fluctuations of the Black Sea level have played a significant role in the existence of the Black Sea polis-cities. The high sea-level during the Novochernomorian transgression is followed by the Phanagorian regression when the sea level reached its minimum of 3 m below the modern sea level during the antiquity (Roman Age). Then, on the west coast of Mandra Lake the Roman polis Deultum was founded which became a flourishing port. The discrepancy between the low sea level and ancient navigation activity in Mandra Lake is a challenge for further investigations of the Holocene sediments.

Published: December 2021

Cochleo-labyrinthopathy (CL) is an affection that in-volves cochlea and vestibular system. It occurs with the association of auditory symptoms (sensorineural hearing loss and tinnitus), vestibular symptoms (objective vertigo, unidirectional horizontal-rotary nystagmus and static or dynamic balance disorders) and neurovegetative signs (nausea, vomiting, pallor, sweating). The diagnosis may be difficult in paediatric age since the child is unable to clearly express their discomfort and symptoms. Multiple causes have been recognized but, in acute cases, infection is the most frequent etiological agent. The paper de-scribes a case of CL due to Herpes Virus 1-2 infection responsive to acyclovir and reports a flow-chart for the diagnostic approach to the vertiginous syndromes in children.

Published: December 2021

Introduction: Sexual violence during childhood and adolescence can impact on neurobiological development, since in this period the maturation of the brain occurs. This research aims to relate trumas as a result of abuse, and examines the lasting neurobiological and behavioral consequences. Methods: Articles were researched in journals specialized in the area on Scielo, Pubmed, LLACs and Medline platforms, using publications between 2010 to 2020. The descriptors used were “sexual violence”, “cellular neurobiology” and “child abuse”. The articles were selected through the descriptors, publication period, portuguese or english works, number of citations and relevance of the work. Results: The research prove that sexual violence in childhood has several consequences for neurobiological development. Cognitive aspects are damaged resulting in negative impact on intellgence, attention, sensory motor functioning, language, memory and, among others, as well as psychiatric symptoms, decrease sense of coherence and increased cortizol concentrations. Neuroimaging studies also show structural changes that can affect various areas of the brain such as the cortex and reduce myelination. Conclusion: All tipes of violence or trauma has consequences, mainly when they are sexual, since brain areas such as the hippocampus, corpus callosum, prefrontal cortex and the anterior cingulate cortex suffer evident changes detected by neuroimaging, having far reaching negative effects to the growth and development of these children.

Background: The traumatic brain injury is one of the main causes of mortality and disability in the world. Objectives: To analyze the current panorama of conservative treatment procedures for mild traumatic brain injury performed in the State of São Paulo and correlate with the current epidemiology. Methods: Literature review and observational, descriptive and transversal data collect on conservative treatment of mild grade traumatic brain injury, available at DATASUS from January 2008 to December 2020 and articles from Scielo, Lilacs and PubMed. Results: There were 150,743 hospitalizations for the conservative treatment of mild traumatic brain injury, being considered of medium complexity. They represent a total expenditure of R$ 64,098,819.38, with 2010 being the year with the highest number of hospitalizations (14,153) and 2011 being the year with the highest amount spent during the period (R$ 5,522,391.52). Of the total procedures, 1,744 are elective and 112,805 are urgent. In the public sector, 53,820 were carried out and 45,050 in the private sector. The total mortality rate was 1.60, corresponding to 2,413 deaths, with 2008 being the year with the highest mortality rate, 2.20 and 2016 had the lowest rate, 1.18. The mortality rate for elective procedures was 1.89 compared to 1.71 for urgent procedures, whereas in the public sector it was 1.73 compared to 1.58 for the private sector. The average total hospital stay was 2.4 days, with an average cost of R$ 425.22. Conclusion: The conservative treatment of traumatic brain injury has a low hospital stay and average cost.

Published: December 2021

Context: Duchenne Muscular Dystrophy (DMD) is an inherited recessive disease linked to the X chromosome, it is a progressive neuromuscular disease most prevalent in the world, affecting 1/3600 male births. It is associated with mutations that lead to loss of dystrophin protein expression, loss of severe muscle, respiratory and cardiac failure. At birth, the signs are generally nonspecific. At 3 years of age there is the appearance of specific changes, starting with muscle weakness, which occurs in an ascending, symmetrical and bilateral manner, becoming evident at around 5 years of age, with difficulty walking, jumping and running, in addition to frequent falls. The disease progresses with cardiorespiratory failure, leading to death between 18 and 25 years. Case Report: Male, 3 years old, with frequent falls, difficulty climbing stairs and rising from the floor, even with support, medical guidance for expectant conduct. At 5 years, clinical worsening, investigation of the condition, changes alteration in the creatinophosphokinase test (8918 U / L), suggesting a hypothesis of Muscular Dystrophy. Karyotype performed, with revelation of genetic changes compatible with DMD. Family heredogram, showing a brother without traits for DMD and a mother with an allele for the disease. The patient evolved with progressive loss of motor functions, reaching inability to move around at 9 years of age and the appearance of cardiac changes - left ventricular systolic dysfunction and extrasystoles. Currently, the patient presents marked movement restriction and undergoes palliative treatment. Conclusions: A DMD relies only on palliative therapy, the recognition of the initial clinical manifestations is essential for its investigation, diagnosis and early treatment, enabling improvement in quality and life expectancy.

Published: December 2021

Context: Inflammatory myofibroblastic tumor (IMT), also known as inflammatory pseudotumor or plasma cell granuloma is a benign tumor of mesenchymal origin that can occur in different anatomical locations, but is more common in the lung and liver, being rare in the central nervous system (CNS). The main challenge when finding this type of tumor in meninges is to make the differential diagnosis with metastatic neoplastic infiltration, granulomatous and infectious diseases. The ideal treatment is complete surgical resection, not requiring other complementary therapies due to its benign behavior. Case report: This work brings the case report of a 22-year-old young man who search medical attention due to headache and after extensive investigation presented the diagnosis of myofibroblastic tumor of the meninges. Conclusion: A comprehensive review of the literature on this type of tumor was carried out in this location, but with very few cases and papers written to date.

Background: Parkinson’s is a neurodegenerative and progressive disease, with an unknown origin that can lead to functional incapacity and decreased quality of life. Objectives: Analyze the number of hospital admissions for Parkinson’s Disease in the Southeast of Brazil. Design and setting: Transversal, descriptive Epidemiologic study between the years of 2011 and 2020 in the Southeast of Brazil. Methods: Study realized using data from the Department of Information of the Brazilian Health System (DATASUS). The variables researched were hospital admissions, age, and year. Results: In the Southeast region, in the determined period, there was an average of 405 hospital admissions per year, an average growth of 4% between the years of 2011 and 2019. However, in 2020, there was a 30% decrease compared to the previous year. It was also observed that in the gap ages between 40 to 49 and 50 to 59 years old, there was a significant increase in the number of hospital admissions. In addition, the age gap between 50 to 80 or more represents an average of 90.88% of all the hospital admissions of the last decade. Conclusion: In the Southeast of Brazil, Parkinson’s Disease had a noticeable absolute reduction of the total admissions analyzed in the last year and a deviation in the average growth of the other years, meaning a possible relation with the COVID-19 pandemic.

Authors: Santos Fernanda Barbosa Gomes dos
Published: December 2021

Background: Euterpe oleracea Martius is an abundant palm in the Amazon region. Its fruit is consumed after pulper processing, to obtain the açaí drink, whose flavonoid-rich composition draws attention to its antioxidant properties and can be used slowing the progression of dementia and others neurological disorders. Objectives: to list what is known at the time of this review regarding the effects of the consumption of the pulp, juice or extract of the fruits of Euterpe oleracea Mart. on the nervous system. DESIGN AND SETTING: literature scan carried out in the PubMed database. Methods: made using the descriptors provided by the DeCS platform: (effects) AND (euterpe oleracea) OR (açaí) AND (nervous system). A total of 33 results were obtained. Using inclusion and exclusion criteria, 24 articles were selected. Results: a positive action of this plant was observed in the modulation of free radicals and prevention of premature aging, which reveals the ability of açaí to delay the natural deterioration of cognitive function that occurs with advancing age. In addition, flavonoids act in the perivascular sheath, aiding in the growth of neuronal cells, containment of neurotoxin-induced neuronal lesions and protecting from others neurotoxical compounds. Conclusions: there is still a need for further studies on this topic to ratify the açaí potential, in order to opening the way for new strategies to protect the nervous system’s functions. As a literature scan, this study does not have a PROSPERO registration.
