On spatially correlated observations in a particle method for subsidence estimation
Authors: Kim Samantha , Vossepoel Femke
Published: October 2022

The particle method is an ensemble-based data assimilation method for state- and parameter estimation in a quasi-static problem. We apply the particle method in two different experiments with models of increasing complexity. The first model, which calculates subsidence for a single observation point due to a single source of strain, considers uncorrelated parameters and observations. In the second model subsidence can be seen as a summation of subsidence contributions from multiple sources. A single source in the second model causes deformation over a region and the observations within this region will be correlated. Assimilating these correlated observations may trigger weight collapse. With synthetic tests we show in a model of subsidence with 50 independent parameters and spatially correlated observations a minimum of 10¹³ particles is required to have information in the posterior distribution identical to that in a model with 50 independent and spatially uncorrelated observations.Spatial correlations cause information loss which can be quantified with mutual information. With synthetic experiments we illustrate how stronger spatial correlation results in a lower information content in the posterior. This quantification underpins our finding that a larger ensemble size is required for the particle method to remain effective in the case of spatial correlation. We furthermore illustrate how this loss of information is reflected in the log likelihood, and how this depends on the number of parameters of the model. Based on the results of these experiments, we propose criteria to evaluate the required ensemble size for data assimilation of spatially correlated fields.
Optimising Renewable Generation Configurations of Off-Grid Green Ammonia Production Systems considering Haber-Bosch Flexibility

Published: October 2022

Green ammonia has received increasing interest for its potential as an energy carrier in the international trade of renewable power. This paper considers Australia’s prospects for green ammonia production from an exporter’s perspective by highlighting Australia’s competitive advantage in renewable resource quality and seasonal complementarity to its potential trade buyers. Although renewable resources are unevenly distributed across Australia and present distinct diurnal and seasonal variability, modelling shows that most of the pre-identified hydrogen hubs in each state and territory of Australia can produce cost-competitive green ammonia providing the electrolysis and Haber-Bosch processes are partially flexible to cope with the variability of renewables. Flexible operation reduces energy curtailment and leads to lower storage capacity requirements using batteries or hydrogen storage, which would otherwise increase system costs. In addition, an optimised combination of wind and solar can reduce the magnitude of storage required. Providing that a partially flexible Haber Bosch plant is commercially available, our modelling shows a levelised cost of ammonia (LCOA) of AU\$756/tonne and AU\$659/tonne in 2025 and 2030, respectively. Based on these results, green ammonia would be cost-competitive with grey hydrogen in 2030, given a feedstock natural gas price higher than AU\$14/MBtu. For green ammonia to be cost-competitive with grey hydrogen, assuming a lower gas price of AU\$6/MBtu, a carbon price would need to be in place of at least AU\$123/tonne. A further factor favouring Australian production of green ammonia is the potential synergy between Southern Hemisphere supply and Northern Hemisphere demand. Given that there is a greater demand for energy in winter concurrent with lower solar power production, there may be opportunities for solar-based Southern Hemisphere suppliers to supply the major industrial regions, most of which are located in the Northern Hemisphere.

Most language use is displaced, referring to past, future or hypothetical events. Displacement poses an important challenge for language learning. How can children learn what words refer to when the referent is not physically available? We suggest that caregivers provide children with iconic vocal and gestural cues that imagistically evoke properties of absent referents to support displaced learning. We collected an audio-visual corpus of English-speaking caregiver-child interactions (N = 71, 24-58 months, 37 female) and annotated the range of vocal and manual behaviours caregivers produced. We found that caregivers used iconic cues especially in displaced contexts, using other cues when objects were present. Thus, we map caregivers’ non-linguistic behaviours, showing that they provide iconic cues to support displaced language learning and processing.
OD HETERONOMII DO (RELATYWNEJ) AUTONOMII. ROZWÓJ POLSKIEGO POLA SZTUKI W LATACH 1945–1981
Authors:   School of Higher Studies in Social Sciences, Paryż, Tyl Maria
Published: October 2022

This article proposes to observe the post-1945 evolution of the Polish field of art from the point of view of the mechanisms that determined its functioning after the Second World War: from heteronomy, characteristic of the Socialist Realism period, to the relative autonomy achieved in the early 1980s. The author divides this history into three stages: 1945–1953 (post-war years and Socialist Realism), 1953–1964 (the Thaw, opening of borders), 1964–1981 (gradual weakening of the central cultural system controlled by the party-state authorities), which she then interprets in analogy to three artistic systems, which are widely discussed in the context of the development of the international field of art from the turn of the 18th century to the 1980s: the academic system, the dealer-critic system, and the dealer-curator system.
NAUKI HISTORYCZNE W PRL: AUTONOMICZNE CZY HETERONOMICZNE? PERSPEKTYWA SOCJOLOGII PÓL
Authors:   National Center for Scientific Research CNRS, France, Behr Valentin
Published: October 2022

Understanding historical policy in Poland as a product of a power struggle taking place at the intersection of several fields (especially the scientific, political, and bureaucratic fields) and involving actors with unequal resources in these different fields allows us to go beyond the previous scholarship on the topic. The structure of the relationship between the bureaucratic field and the scientific field is partly determined by the actions of effective actors, in this case historians, who support a historical policy. Viewed from a relatively long sociohistorical perspective, the structure of the relationship between these fields reveals a form of continuity, characterized by the existence of a pole of production of official history, but also remarkable evolutions: at several moments during the Polish People’s Republic, historians most equipped with scientific capital were able to maintain a form of autonomy of historiographical production in the face of orders from the authorities.

Authors:   Center of Laser and Informational Biophysics, Orenburg State University, Orenburg, Russia, Kucherenko M.G.
Published: October 2022

Gold nanowires with polyelectrolytes adsorbed on their surface are widely used in various biomedical research. In this work, for the first time, conformationalchanges in polyelectrolytes on the surface of a gold nanowire transversely polarized in an external electric field were considered. The properties of a specially created analytical model of conformational rearrangements of a Gaussian macromolecular chain adsorbed on the surface of a cylindrical metal nanowire in an external electric field transverse to the axis of the nanowire were investigated. Conformational changes of uniformly charged polypeptides on the surface of a transversely polarized gold nanowire have been studied using molecular dynamics simulation. On the basis of the analytical model and the results of molecular dynamics simulation, the spatial distributions of the density of polyelectrolyte units on the surface of the nanowire were constructed. With an increase in the strength of the external electric field, an asymmetric stretching of the polyelectrolyte fringe in the direction of the dipole moment of the transversely polarized nanowire was observed.

Authors:   E.A. Buketov Karaganda University, Karaganda, Kazakhstan, Karabekova D.Zh.
Published: October 2022

The problems and prospects of application of non-destructive testing methods for technical diagnostics of the thermal networks state and various technological objects are discussed. The recording of the temperature state of thermal processes by using a flow meter is due to its sensitivity to the change of thermophysical characteristics and the ability to control without the use of an external energy source, etc. The description of the developed device to measuring of the heat flow using of a thermoelectric heat flow converter of a special design is shown. A distinctive feature of the device is the heating element that installed on an insulating layer serving as a support surface. Calibration of the device is proposed to be carried out by replacing the heat flow from the investigated object with the heat flow released in the heating element when an electric current passes through it. The developed device can register the changes in the heat flux density in the range of (25-100) W/m2, which allows it possible to detect the smallest thermal insulation defects.

Authors: Xu Xiao-Ying , Li Da , Song Lai-Rong , Liu Pan-Pan , Wu Ze-Yu , Wang Liang , Zhang Li-Wei , Zhang Jun-Ting , Wu Zhen
Published: October 2022

OBJECTIVE

In this study, the authors aimed to create a nomogram for precisely predicting the 5-year prospective hemorrhage risk in brainstem cavernous malformations (BSCMs).

METHODS

Patients with confirmed BSCMs in a single-center prospective observational series from January 2012 to December 2016 were included in the present study for nomogram building and validation. The concordance index (C-index), calibration curves, and decision curve analysis were used to evaluate the predictive accuracy, discriminative ability, and clinical usefulness of the nomogram. Then, a nomogram-based risk stratification model for untreated BSCMs was developed.

RESULTS

In total, 600 patients were included in the study; 417 patients who had been enrolled before July 2015 were divided into the training and validation cohorts, and 183 subsequently enrolled patients were used as the external validation cohort. By applying a backward stepwise procedure in the multivariable Cox model, variables, including prior hemorrhage (HR 1.69), hemorrhage on admission (HR 3.33), lesion size > 1.5 cm (HR 1.84), lesion depth (HR 2.35), crossing the axial midpoint (HR 1.94), and developmental venous anomaly (HR 2.62), were incorporated to develop a nomogram. The Harrell C-index values for a 5-year prospective hemorrhage were 0.752 (95% CI 0.687–0.816), 0.801 (95% CI 0.665–0.936), and 0.758 (95% CI 0.674–0.842) in the training, internal validation, and external validation cohorts, respectively. The nomogram performed well in terms of consistency between prediction and actual observation according to the calibration curve. The patients could be classified into three distinct (low, medium, and high) risk groups using the final score of this nomogram.

CONCLUSIONS

Independent predictors of the 5-year hemorrhage risk in untreated BSCMs were selected to create the first nomogram for predicting individual prospective hemorrhage. The nomogram was able to stratify patients into different risk groups and assist in clinical decision-making.

Published: October 2022

OBJECTIVE

In drug-resistant temporal lobe epilepsy, automated tools for seizure onset zone (SOZ) localization that use brief interictal recordings could supplement presurgical evaluations and improve care. Thus, the authors sought to localize SOZs by training a multichannel convolutional neural network on stereoelectroencephalography (SEEG) cortico-cortical evoked potentials.

METHODS

The authors performed single-pulse electrical stimulation in 10 drug-resistant temporal lobe epilepsy patients implanted with SEEG. Using 500,000 unique poststimulation SEEG epochs, the authors trained a multichannel 1-dimensional convolutional neural network to determine whether an SOZ had been stimulated.

RESULTS

SOZs were classified with mean sensitivity of 78.1% and specificity of 74.6% according to leave-one-patient-out testing. To achieve maximum accuracy, the model required a 0- to 350-msec poststimulation time period. Post hoc analysis revealed that the model accurately classified unilateral versus bilateral mesial temporal lobe seizure onset, as well as neocortical SOZs.

CONCLUSIONS

This was the first demonstration, to the authors’ knowledge, that a deep learning framework can be used to accurately classify SOZs with single-pulse electrical stimulation–evoked responses. These findings suggest that accurate classification of SOZs relies on a complex temporal evolution of evoked responses within 350 msec of stimulation. Validation in a larger data set could provide a practical clinical tool for the presurgical evaluation of drug-resistant epilepsy.
Presence of a fundal fluid cap on preoperative magnetic resonance imaging may predict long-term facial nerve function after resection of vestibular schwannoma via the retrosigmoid approach
Authors: Fujita Yuichi , Uozumi Yoichi , Sasayama Takashi , Kohmura Eiji
Published: October 2022

OBJECTIVE

Preservation of neurological function is a priority when performing a resection of a vestibular schwannoma (VS). Few studies have examined the radiographic value of a fundal fluid cap—i.e., cerebrospinal fluid in the lateral end of a VS within the internal auditory canal—for prediction of postoperative neurological function. The aim of this study was to clarify whether the presence of a fundal fluid cap on preoperative magnetic resonance images has a clinical impact on facial nerve function after resection of VSs.

METHODS

The presence of a fundal fluid cap and its prognostic impact on long-term postoperative facial nerve function were analyzed.

RESULTS

A fundal fluid cap was present in 102 of 143 patients who underwent resection of sporadic VSs via the retrosigmoid approach. Facial nerve function was acceptable (House-Brackmann grade I–II) immediately after surgery in 82 (80.4%) patients with a fundal fluid cap and in 26 (63.4%) of those without this sign. The preservation rate of facial nerve function increased in a time-dependent manner after surgery in patients with a fundal fluid cap but plateaued by 3 months postoperatively in those without a fundal fluid cap; the difference was statistically significant at 12 months (96.1% vs 82.9%, p = 0.013) and 24 months (97.1% vs 82.9%, p = 0.006) after surgery. The presence of a fundal fluid cap had a significantly positive effect on long-term facial nerve function at 24 months after surgery when tumor size and intraoperative neuromonitoring response were taken into account (OR 5.55, 95% CI 1.12–27.5, p = 0.034).

CONCLUSIONS

Neuromonitoring-guided microsurgery for total resection of VSs is more likely to be successful in terms of preservation of facial nerve function if a fundal fluid cap is present. This preoperative radiographic sign could be helpful when counseling patients and deciding the treatment strategy.
Toward a Curiosity Mindset: Reframing the Problem of Student Disengagement from Classroom Instruction
Authors: Oliveira Alandeon W , Lathrop Robert
Published: October 2022

Reduced student engagement in formal instruction is a problem that pervades classrooms across the educational spectrum. Students have been shown to commonly experience the negative emotions of boredom and inattentiveness (Bunce, Flens, & Neiles, 2010; Mann & Robinson, 2009; Young, Robinson, & Alberts, 2011) as well as vigilance decrement (Grier et al., 2003). Studies have revealed that more than 40% of high-school students usually remain disengaged from learning (Usher and Kober, 2012) and few (as little as 8%) reach a developmental level characterized by intrinsic motivation, attention, and effort (Lawson & Masyn, 2015; Scherrer & Preckel, 2018). Because student interest in the instructional topics and pedagogical activities rapidly decreases or is completely lost, students withdraw their attention from instruction in favor of off-task behaviors such as daydreaming, doodling, or inappropriate use of technology (Adams, 2006; Bugeja, 2007; Fink, 2010; Gilroy, 2004; Nworie & Haughton, 2008). Despite teachers’ best efforts, maintaining high levels of student interest during class time and avoiding disengagement from the learning process constitutes a challenging pedagogical endeavor, particularly in the context of classroom discussions and lectures (Lemke, 1990; Nunn, 1996).

Published: October 2022

The use of the zonal-block model of the earth's crust for the construction of regional tectonic schemes and sections of the earth's crust based on a complex of geological and geophysical data makes it possible to consider the resulting maps and sections as tectonic models. The main elements of such models are blocks with an ancient continental base and interblock zones formed by complexes of island arcs, an accretionary prism, or oceanic crust. The developed geotectonic model of the Sea of Okhotsk region reflects the features of the deep structure, tectonics, and geodynamics. The Cimmerian Novosibirsk-Chukotka, Verkhoyansk-Kolyma, Kolyma-Omolon, and Amur folded regions and the Alpides of the Koryak-Kamchatka and Sakhalin-Sikhote-Alin folded regions are developed along the northern, western, and southern boundaries of the Sea of Okhotsk megablock with a continental crust type. From the east, the megablock is limited by oceanic basins and island arcs.

Floridian Consumer Perceptions of Local Versus Organic Ornamental Plants
Authors: Khachatryan Hayk , Rihn Alicia
Published: October 2022

Horticultural consumers in Florida are interested in local and organically produced plants. But these terms can mean different things in different regions. UF/IFAS researchers conducted a survey last summer which suggests that consumers in central Florida define local as plants that are grown near where they are sold and identify the most important local benefits as product safety, quality, and community support. Organic plants are perceived as requiring fewer chemical additives and being healthier for the environment. The importance of these traits varies by plant type.

Authors: Schneider Keith R. , Silverberg Rachael , Chang Alexandra , Goodrich-Schneider Renée M.
Published: October 2022

Clostridium botulinum is ubiquitous in nature, often found in soil and water. The bacteria and spores alone do not cause disease, but they produce the botulinum toxin that causes botulism, a serious paralytic condition that can lead to death. Although it is one of the least common of the foodborne diseases, anyone is susceptible even with the ingestion of only a small amount of toxin present in contaminated food. Immunocompromised individuals, young children, and elderly individuals may suffer from more serious symptoms. This revised 6-page fact sheet was written by Keith R.

Zombie Fly (suggested common name) Apocephalus borealis Brues (Insecta: Diptera: Phoridae)
Authors: Casuso Nicole , Mortensen Ashley N. , Ellis James D.
Published: October 2022

The zombie fly is primarily a parasitoid of bumble bees and wasps in North America. In 2012, Dr. John Hafernik and his colleagus at San Francisco State University discovered that Apocephalus borealis also parasitizes honey bees. Parasitized honey bees show zombie-like behavior by leaving their hives at night and are often attracted to nearby lights where they show disoriented behavior and die in a few hours. This 5-page fact sheet was written by Nicole A. Casuso, Ashley N. Mortensen, and James D. Ellis, and published by the UF Department of Entomology and Nematology, October 2014.

Robbing Behavior in Honey Bees
Authors: Willingham Ryan , Klopchin Jeanette , Ellis James D.
Published: October 2022

Western honey bee workers can invade and steal honey/nectar from other colonies or sugar/corn syrup from feeders used to deliver syrup to other colonies. This is called “robbing” behavior. Robbing behavior typically involves the collection of nectar and honey, but not pollen or brood. Some beekeepers report that robbing bees may steal wax or propolis from other hives, but there is not much data available on this occurrence. Robbing behavior can escalate quickly from just a few bees robbing other colonies to a massive frenzy of bees robbing many colonies in an apiary. This 3-page fact sheet was written by Ryan Willingham, Jeanette Klopchin, and James Ellis, and published by the UF Department of Entomology and Nematology, February 2015. (Photo Credit: UF/HBREL)

Tawny Crazy Ant (previously known as Caribbean crazy ant) Nylanderia (formerly Paratrechina) fulva (Mayr) (Insecta: Hymenoptera: Formicidae: Formicinae)
Authors: Sharma Shweta , Warner John , Scheffrahn Rudolf H.
Published: October 2022

Nylanderia fulva is part of a group of ants referred to as “crazy ants” due to their quick and erratic movements. It has been reported from 27 counties of Florida and 27 counties of Texas, as well as from Louisiana, Mississippi, Alabama, and Georgia. Huge number of workers in infested areas can make human activities uncomfortable and difficult. They can infest sidewalks, buildings and gardens, and damage phone lines, air conditioning units and computers. They have killed honey bee larvae and used the hives as their nests, and are even displacing red imported fire ants where the two populations overlap in Texas. This 5-page fact sheet was written by Shweta Sharma, John Warner, and Rudolph H. Scheffrahn, and published by the UF Department of Entomology and Nematology, December 2014.

Ecosystem Services Valuation for Estuarine and Coastal Restoration in Florida
Authors: Blair Susanna , Adams Carrie , Ankersen Tom , McGuire Maia , Kaplan David
Published: October 2022

Throughout Florida’s history, humans have altered the coastlines, leading to large-scale degradation of coastal ecosystems. This has led to the loss of associated ecosystem services, including products such as food and timber, and processes like coastal protection and disease control. Unfortunately, ecosystem restoration efforts have not always been a priority for coastal management. This 10-page literature review surveys the available ecosystem-service valuation literature for five of Florida’s coastal natural communities—oyster reefs, beach dunes, mangrove forests, seagrass beds, and salt marshes—to facilitate the quantification of ecosystem services to provide a better measure of the full impact of restoration efforts. Written by Susanna Blair, Carrie Adams, Tom Ankersen, Maia McGuire, and David Kaplan, and published by the UF Department of Sea Grant, January 2015. (UF/IFAS photo by Tyler Jones)

Contaminants in the Urban Environment: Pharmaceuticals and Personal Care Products (PPCPs)—Part 2
Authors: Yang Yun-Ya , Toor Gurpal S.
Published: October 2022

Pharmaceuticals and personal care products contain a variety of chemical substances that enter household wastewater from bath and shower, sinks, and washers and ultimately find their way into the environment. Continuous discharge of wastewater contributes to the accumulation of these substances in the environment — where they can be harmful to organisms. This publication is part of a series titled Contaminants in the Urban Environment. This series is intended to give state and local government officials, soil scientists, consulting engineers, extension agents, and citizens (1) a basic understanding of the occurrence, toxic effects, and source of various contaminants in the environment and (2) guidance on ways to protect human and environmental health. This 9-page fact sheet discusses the sources and impacts of PPCPs and offers common-sense ways we can protect our environment from PPCPs. Written by Yun-Ya Yang and Gurpal S.
