Update of Brazilian Heat Flow Data, within the framework of a multiprong referencing system
Authors: Hamza Valiya , Vieira Fabio , Gomes Jorge Luiz dos Santos , Guimaraes Suze , Alexandrino Carlos , Gomes Antônio
Published: March 2020

An updated heat-flow database for Brazil is presented providing details of measurements carried out at 406 sites. It has been organized as per the scheme proposed by the International Heat Flow Commission. The data sets refer to results obtained using methods referred to as interval temperature logs (ITL), underground mines (UMM), bottom-hole temperatures (BHT), stable bottom temperatures (SBT) and water wells (AQT). The compilation provides information on depths of temperature logs, gradient determinations, measurements of thermal conductivity and radiogenic heat production. Also included is information on the methods employed and error estimates of the main parameters. A new heat flow map of Brazil has been derived based on the updated data set. A multipronged system has been employed in citing references, where the indexing scheme adopted follows chronological order. It provides information not only on the primary work concerning heat flow determination but also later improvements in measurements of main parameters (temperature gradients, thermal conductivity and radiogenic heat production) as well as techniques employed in data analysis.
Geothermal Gradients and Heat Flow in Norte Basin of Uruguay
Authors: Morales Ethel , Pedro Agostina , De León Ricardo
Published: March 2020

Progress obtained in a partial update of geothermal gradient and terrestrial heat flow values for the Norte Basin (Uruguay) are presented. It is based on results of temperature measurements carried out in deep water wells. Most of these wells have intersected the southern part of the Guarani Aquifer System, at depths varying from 200 to 1500m. In most of the Norte Basin it is a confined aquifer capped by the flood basalts of Cretaceous age. The results indicate that temperature gradients fall in the range of 15 to 45oC/km and the thermal conductivity of basalts have a mean value of 2.2W/m/K. Analysis of temperature distributions indicate that heat transfer takes place not only by conduction but also by upflow of groundwater with velocities in the range of 10-9 to 10-8 m/s. The representative mean heat flow values fall in the range of 30 to 85mW/m2. Maps of spatial distributions of geothermal gradients and heat flow values have been considered as indicative of the possible existence of an anomalous geothermal zone in the central-northwestern part of the Norte Basin. There are indications that this anomalous geothermal zone extends also to the eastern parts of adjacent regions in Argentina. Theoretical values derived on the basis of spherical harmonic expansion, employed in estimating geothermal gradients and heat flow points to a zone of relatively low heat flow in the other regions of the Norte Basin.
Differences Between Recent Heat Flow Maps of Poland and Deep Thermo-Seismic and Tectonic Age Constraints
Authors: Majorowicz Jacek Andrew , Grad Marek
Published: March 2020

Poland is situated in a place of contacts between three continental scale geologic structural units: the Precambrian East European Craton (EEC) to the northeast, the Variscan West European Platform (WEP) terranes to the southwest, and the younger Carpathian Alpine arc in the south. The Trans-European suture zone (TESZ) between the EEC and WEP is a deep-seated discontinuity zone reaching down to a depth of about 200 km. The conjunction of all these continental scale geologic units is reflected in the complex tectonic structure of this area. Apart from the complex seismic structure, this area is also associated with pronounced gravity, magnetic and heat flow anomalies. Significant differences exist between heat flow maps of Poland published in recent works, with values reaching 20 to 30 mWm-2. Examples are differences in heat flow based on models that use well log interpreted mineral and porosity content and assigned world averages of rock and fluid thermal conductivities versus ones based on averaging thermal conductivity values measured using borehole cores only. These differences in heat flow between the methods are discussed in the context of their relationship with tectonic age. Also considered are depth differences between lithosphere – asthenosphere boundary (LAB) derived from thermal model vs those that obey seismological constraints. Higher heat flow estimates reaching up to or more than 100 mWm-2, based on conductivity values derived from well-logs, are found to be quite improbable. This likely reason for overestimate of heat flow is discussed.
Numerical Simulations of Terrestrial Heat Flow in the Beiras Region, Mainland Portugal
Authors: Duque Maria Rosa Alves
Published: March 2020

Numerical simulations of heat flow density have been made for ten localities in the Beiras region of central Portugal where observational data are absent. The procedure adopted is based on results of deep crustal geophysical surveys and consider that the heat flow measured at the surface of the Earth results from the addition of heat generated in the crust by radioactive sources to that coming from the mantle. Radioactive heat sources in the region are heterogeneous and heat flow values at the surface depends on the thickness of upper crustal layers. Geotherms were obtained considering heat flow by conduction in the vertical direction. The models employed make use of data derived from geophysical surveys of Moho depths and detailed results related with seismic velocity distribution in the crust. In addition, results of radiometric surveys were employed in deriving heat production values for upper layers of the crust. A value around 35 mW m-2 was assumed for heat flow from the mantle. The resulting heat flow density values are similar to those found for areas with similar tectonic characteristics in NW Africa and in Southern Portugal.
Daily temperature variations at the subsurface combined with water level records in Ajameti, Georgia
Authors: Buntebarth Guenter , Jimsheladze Tamar , Kobzev Genadi , Melikadze George
Published: March 2020

High resolution temperatures at the subsurface down to 250 m and water level measurements were carried out in a borehole at Ajameti, Georgia. In both cases daily variations were analyzed for time periods of February/March 2018 and April 2018. Their frequency spectra demonstrate that the diurnal and semi-diurnal variations are generated by earth tides. The enhanced amplitude of the diurnal period at depth of 100 m coincides with the growth phase of vegetation. Frequent rainfall did not affect the temperature at 100 m or deeper but raises the water level. Daily surface temperature variations relate to the temperature variation at the subsurface during the growth phase of vegetation in April and down to 175 m. No relation is detected in records obtained during February/March and at 250 m in both cases. Vertical shift of the water column results from the prevailing temperature gradient and the temperature fluctuation. The estimated water flow yields an amplitude of 0.1 m at 250 m but increases continuously to 0.16 m at 100 m. However, the water level variation reaches only 0.03 m at the surface. It is likely that the free surface of the water level has an additional degree of freedom which causes the lower magnitude of fluctuation.

Please, Please, Just Tell Me: The Linguistic Features of Humorous Deception
Authors: Skalicky Stephen , Duran Nicholas , Crossley Scott A.
Published: March 2020

Prior research undertaken for the purpose of identifying deceptive language has focused on deception as it is used for nefarious ends, such as purposeful lying. However, despite the intent to mislead, not all examples of deception are carried out for malevolent ends. In this study, we describe the linguistic features of humorous deception. Specifically, we analyzed the linguistic features of 753 news stories, 1/3 of which were truthful and 2/3 of which we categorized as examples of humorous deception. The news stories we analyzed occurred naturally as part of a segment named Bluff the Listener on the popular American radio quiz show Wait, Wait…Don’t Tell Me!. Using a combination of supervised learning and predictive modeling, we identified 11 linguistic features accounting for approximately 18% of the variance between humorous deception and truthful news stories. These linguistic features suggested the deceptive news stories were more confident and descriptive but also less cohesive when compared to the truthful new stories. We suggest these findings reflect the dual communicative goal of this unique type of discourse: to simultaneously deceive and be humorous.
Forecasting spatial, socioeconomic and demographic variation in COVID-19 health care demand in England and Wales
Authors: Verhagen Mark D. , Brazel David M. , Dowd Jennifer Beam , Kashnitsky Ilya , Mills Melinda
Published: March 2020

COVID-19 poses one of the most profound public health crises for a hundred years. As of late March 2020, over 25,000 deaths and above a half million confirmed cases were registered across more than 175 countries or regions. The virus will infect a sizeable proportion of the worlds population, leading to unprecedented pressures on national health care systems. Although national estimates of hospital bed capacity are available, these obscure important differences at local and regional levels. COVID-19 appears especially dangerous for the oldest age groups and those with serious comorbidities. It is crucial to understand how health system capacity matches local variations in population structure. Using England and Wales, we illustrate how the interaction of local demography, a high burden of COVID-19 hospitalization at older ages, and regional variation in hospital resources may culminate in "hospital deserts" with too few resources to cope with a wave of critical cases. We demonstrate how local capacity could rapidly become overwhelmed. By providing fine-grained local estimates of expected hospitalization, we identify areas that have higher risks of health care burden. An online companion to this paper can be used by policymakers to identify and monitor high-risk areas, and predict the expected healthcare demand in real-time as the actual epidemic spreads. This agile knowledge will be invaluable to tackle the enormous logistical challenge COVID-19 will pose to health care systems.

“Pervasive ocular tremor of Parkinson’s” is not pervasive, ocular, or uniquely parkinsonian
Authors: MacAskill Michael R. , Myall Daniel J.
Published: March 2020

A putative tremulous oscillation of the eyes has been proposed to provide the long-sought objective, sensitive and specific diagnostic sign for Parkinson’s disease . Vigorous debate has ensued as to whether this “ocular tremor” is a real phenomenon or an artefact secondary to head motion. Contradictory arguments have centred on the capabilities of magnetic movement measurement technologies, with small numbers of illustrative cases presented to bolster either side. A large, definitive study able to either confirm or reject the original finding on a purely oculographic basis was required. We examined 681 oculomotor recordings from a longitudinal study of 188 Parkinson’s patients and 66 controls. Fourier analysis was used to detect oscilla- tions not only in their raw pupil motion data but also in corneal reflection signals, which can correct for head motion. We replicated the original authors’ findings inasmuch as we detected oscillations in raw pupil position data that often occurred in their reported frequency range of 5.7 ± 3 Hz. They were not, however, present universally in patients and the frequency (if not power) distribution was similar in controls. Crucially, oscillations in that frequency range were abolished when corneal reflection correction was applied to compensate for head-motion. The oscillations in the uncorrected data were strongly related to clinical ratings of somatomotor tremor severity. We found strong evidence that the postulated purely ocular tremor of Parkin- son’s does not exist, other than as an artefact arising from head motion secondary to somatic tremor.

We present an interactive, comparative visualization approach for the exploration of these annotation data with the goal of analyzing the nature of text variance in this work. The approach combines a set of coordinated close and distant reading views in an overview+detail design and provides means for category-filtering and detailed inspection of the data. We conducted a task and requirement analysis in cooperation of the involved medievalists and visualization researchers and sketch two scenarios of usage.

Generalization at retrieval using associative networks with transient weight changes
Authors: Shabahang Kevin D. , Yim Hyungwook , Dennis Simon
Published: March 2020

Without having seen a bigram like “her buffalo” before, you can easily tell that it is grammatical because “buffalo” can be aligned with more common nouns like “cat” or “dog” that have been seen in contexts like “her cat” or “her dog” -- the novel bigram structurally aligns with representations in memory. We present a new class of associative nets we call Dynamic-Eigen-Nets, and provide simulations that show how they generalize to patterns that are structurally aligned with the training domain. Linear-Associative-Nets respond with the same pattern regardless of input, motivating the introduction of saturation to facilitate other response states. However, models using saturation cannot readily generalize to novel, but structurally aligned patterns. Dynamic-Eigen-Nets address this problem by dynamically biasing the eigenspectrum towards external input using temporary weight changes. We demonstrate how a two-slot Dynamic-Eigen-Net trained on a text corpus provides an account of bigram judgement-of-grammaticality and lexical decision tasks. We end with a simulation showing how a Dynamic-Eigen-Net is sensitive to syntactic violations introduced in bigrams, even after the association encoding those bigrams is deleted from memory. We propose Dynamic-Eigen-Nets as associative nets that generalize at retrieval, instead of encoding, through recurrent feedback.
The cognitive cost of semantic recoding: An eye-tracking study on arithmetic word problem solving
Authors: Gros Hippolyte , Sander Emmanuel , Thibaut Jean- Pierre
Published: March 2020

In this study, we investigate the cognitive mechanisms underlying arithmetic word problem solving, focusing specifically on the process of semantic recoding and its cognitive implications. Semantic recoding has been hypothesized to be the process involved in representational change necessary to solve a problem whose initial encoding is semantically incongruent with its solution (Gros et al., 2020). To quantify the cognitive cost associated with this recoding, we used behavioral and eye-tracking measures, analyzing pupil dilation, response times, backward eye movements, as well as fixation times. We asked 50 pre-service teachers to complete a solution validity assessment task. We compared participants’ gaze patterns on isomorphic problems to gather insights into their encoded representations. On problems designed to require a semantic recoding, we found that specific sentences describing elements relevant in a semantically incongruent representation of the problems but irrelevant otherwise were looked at longer and were the focus of a higher number of backward eye movements. Additionally, an increase in pupil dilation and response time on correctly solved incongruent problems supported the idea that participants need to engage in a cognitively costly recoding process when facing semantic incongruence.

Semantic associates create retroactive interference on an independent recall task
Authors: Antony James , Bennion Kelly
Published: March 2020

Semantic similarity between stimuli can cause false memories, but the extent to which it causes retroactive interference in recall has been less explored. Here, subjects learned unique locations for “critical” words that reliably produce false memories in the Deese-Roediger-McDermott paradigm. Next, subjects centrally viewed words that were semantically associated with half of the critical words. Finally, subjects retrieved the critical word locations (to test recall) and distinguished them from previously unseen words (to test recognition). We found spatial memory impairments for critical words whose semantic associates were shown (vs. not shown), suggesting that semantic material caused retroactive interference, even on a test of unrelated content (i.e., spatial versus semantic). This effect was present in three experiments when the interfering information was presented shortly before spatial recall, but not after a one-hour delay between associate learning and test or after swapping the order of the spatial and associate phases. Moreover, impairments occurred whether or not subjects were aware of the semantic relatedness between critical and associate words and consistently occurred when the associates had low-to-moderate strength in predicting the critical words. By contrast, swapping the order of the two learning phases increased critical word recognition in a manner that scaled linearly with associate-to-critical word strength. These findings suggest that memory impairments can occur solely via semantic associates on an independent task where all relevant responses are freely available; in this way, they cannot be attributed to any conventional account of retroactive interference.

Keloids of the Lower Abdomen, Mons and Vulva: Several Case Studies Highlighting a Successful Approach to Treatment
Authors: Butler Paris D. , Ligh Cassandra A , Magoon Katie , Butler Paris D.
Published: March 2020

Background: Perineal keloids can have an overwhelming impact on patients’ lives including pain, skin
breakdown, infection, and interference with intercourse. There is a paucity of literature addressing the
effective treatment techniques.
Cases: Three case of perineal keloid treatment, with at least 13-month follow up, are presented. All patients
are African American females who were recommended a treatment plan that combined surgical wide local
excision and radiation therapy. All patients had aesthetically acceptable outcomes with recurrence-free results
at least 13-months post procedure.
Conclusions: These three cases describe the successful treatment of perineal keloids that utilize a
combination of surgical excision with targeted radiotherapy. This approach can be offered to patients with
recurrent keloidal masses and the presented principles can be utilized to achieve recurrence-free results.
Teaching Points: 1. Readers will understand the basics of the pathophysiology of keloid formation and their
effect on patients who experience them in sensitive areas such as the mons, vulva, and/or lower abdomen. 2.
Readers will be able to describe and implement the described technique for management of keloids in these
potentially sensitive areas.
