Distribution-free changepoint detection tests based on the breaking of records
Authors: Castillo-Mateo Jorge
Published: July 2022

The analysis of record-breaking events is of interest in fields such as climatology, hydrology or anthropology. In connection with the record occurrence, we propose three distribution-free statistics for the changepoint detection problem. They are CUSUM-type statistics based on the upper and/or lower record indicators observed in a series. Using a version of the functional central limit theorem, we show that the CUSUM-type statistics are asymptotically Kolmogorov distributed. The main results under the null hypothesis are based on series of independent and identically distributed random variables, but a statistic to deal with series with seasonal component and serial correlation is also proposed. A Monte Carlo study of size, power and changepoint estimate has been performed. Finally, the methods are illustrated by analyzing the time series of temperatures at Madrid, Spain. The R package publicly available on CRAN implements the proposed methods.

We study defining inequalities of string cones via a potential function on a reduced double Bruhat cell. We give a necessary criterion for the potential function to provide a minimal set of inequalities via tropicalization and conjecture an equivalence.
Thermal Influences on Shells: an Archaeological Experiment from the Tropical Indo-pacific
Authors: Oertle Annette , Szabó Katherine
Published: July 2022

Thermal influences on marine molluscs are poorly understood across all disciplines, including archaeology. This presents potential issues for further analysis including radiocarbon dating and stable isotope analysis, as well as hindering our understandings of processing and preparation methods for shell in the past. Different methods of burning or heating may not always leave visual signs on a shell; however, a variety of structural and chemical changes may take place. Here, we present an experimental study using modern-day shells of five tropical marine species designed to explore how various thermal interventions modified shells in terms of microstructure (scanning electron microscope) and mineralogy (X-ray diffraction). We found distinct differences between the taxa using varied temperatures and durations, with shell microstructure playing a key role in responses to thermal stresses. This study highlights the importance of acknowledging this variation, both when structuring research as well as seeking to interpret archaeological shell remains.
The Anisotropic Magnetocaloric Effect and Size-Dependent Magnetic Properties of Iron Particles
Authors: N. Halool Ahmed , Aly Samy H. , Yehia Sherif , Mohammad Fatema Z.
Published: July 2022

We present a theoretical study on the anisotropic magnetocaloric effect and the size-dependent magnetic properties of Fe particles of radii in the range 25–150 Å. An observable increase has been found in the magnetization, of the low radii (25–75 Å) particles, by reducing the temperature to 4 K. The anisotropic isothermal change in entropy ΔSm has been calculated by taking the difference between maximum ΔSm along the easy [100] and hard [111] directions. The maximum anisotropic ΔSm is 0.015 J/kg K for a field change of 500 Oe along the [100] direction. The ΔSm temperature dependence exhibits a table-like plateau for small radii (25–75 Å) and in low fields below 300Oe. This enhances the relative cooling power (RCP) of the Fe element to be 8.11 J/kg for particles of 25 Å radius. Also, the calculation of anisotropic ΔTad was performed along the easy axis and showed an increase in the maximum value around 37% relative to the experimental conventional value.
How to gain evidence for causation in disease and therapeutic intervention: from Koch’s postulates to counter-counterfactuals
Authors: Evans David W.
Published: July 2022

Researchers, clinicians, and patients have good reasons for wanting answers to causal questions of disease and therapeutic intervention. This paper uses microbiologist Robert Koch’s pioneering work and famous postulates to extrapolate a logical sequence of evidence for confirming the causes of disease: association between individuals with and without a disease; isolation of causal agents; and the creation of a counterfactual (demonstrating that an agent is sufficient to reproduce the disease anew). This paper formally introduces counter-counterfactuals, which appear to have been used, perhaps intuitively, since the time of Koch and possibly earlier. An argument is presented that counter-counterfactuals (disease-preventers) are a useful tool for identifying necessary causes of disease, and sometimes must be used in place of isolation which is not always possible. In addition, a logical sequence of causal evidence for a therapeutic intervention is presented: creating a counterfactual (demonstrating that the intervention is sufficient to change the natural course of a disease), comparisons between subjects in receipt of treatment versus those who are not (typically within a randomised controlled trial, which can quantify effects of intervention), and counter-counterfactuals (treatment-preventers, which can identify the intervention’s mechanisms of action).
Silencing Itch in human peripheral blood monocytes promotes their differentiation into osteoclasts
Authors: Read O. J. , Harrison D. J.
Published: July 2022

Introduction

Two clinical case reports of humans with mutations in Itch reported distinct morphological defects such as stunted growth, macrocephaly, and dysmorphic features indicating a role for Itch in bone remodelling. Studies in mice have found that the encoded E3 ubiquitin ligase acts as a negative regulator of osteoclastogenesis, however no studies have investigated whether this is translatable to a human model.

Experimental procedures

Human peripheral blood monocytes were separated from whole blood and grown in M-CSF containing media. Media was later supplemented with RANKL to promote osteoclast differentiation. Transient siRNA-mediated Itch knockdown (si-Itch) in monocytes was verified by qPCR and western blot to confirm reduction in both Itch mRNA and protein respectively. Monocytes were aliquoted onto 96-well plates where confluence and osteoclast formation were analysed using automated cytometry analysis before and after staining for tartrate resistant acid phosphatase activity (TRAP). Cells were also stained with Hoechst33342 to look for multinucleate cells.

Results

Cells treated with si-Itch showed an 80% knockdown in Itch mRNA and > 75% reduction in protein. Following the 7-day differentiation period, si-Itch caused a 47% increase in multinucleate cells and a 17% increase in numbers of large cellular bodies and, indicating an overall increase in mature osteoclast formation.

Conclusions

Our preliminary data shows silencing Itch expression increases the potential of primary human monocytes to differentiate into osteoclast-like cells in vitro.
The development of a social-sexual education program for adults with neurodevelopmental disabilities: starting the discussion
Authors: Pedgrift Kathryn , Sparapani Nicole
Published: July 2022

People with neurodevelopmental disabilities, including intellectual disabilities and autism, want to have relationships but few are given the tools and opportunity to create those relationships in a safe and meaningful way. This strong desire to have relationships, coupled with reduced access to information, puts people with neurodevelopmental disabilities at high risk for being targets of sexual abuse and exploitation, as well as demonstrating social-sexual behavior that is unexpected or offensive to others. Research has long demonstrated that people with intellectual disabilities are sexually assaulted at much higher rates than the general population. In addition, it is common for people with intellectual disabilities and autism to miss out on employment, housing, and social opportunities due to unexpected social-sexual behaviors. To address this need, the research team developed the social-sexual education (SSE) program to teach people with neurodevelopmental disabilities how to create safe and meaningful relationships while also giving them information about sexual abuse and coercion. We recruited licensed professionals to pilot test the SSE program, and then we evaluated the tool using quantitative and qualitative methods. Our findings provide preliminary support for the SSE program. Implications and future directions are discussed.
Proteome and physiological analyses reveal tobacco (Nicotiana tabacum) peroxidase 7 (POD 7) functions in responses to copper stress

Published: July 2022

Copper is a micronutrient essential for plant growth and development. However, Cu is also a heavy metal element that has deleterious impacts on plants when excessively accumulated in the environment. To understand the molecular mechanism underlying tobacco in response to Cu stress, iTRAQ based technology was used to identify differentially expressed proteins (DEPs) and important metabolic pathways in tobacco plants treated with excessive CuSO4. The results showed that 180 DEPs were detected between the treatment and control, among which 78 were upregulated and 102 were downregulated. These DEPs can be functionally divided into 65 categories and are closely related to metabolic pathways, carbon metabolism, secondary metabolite biosynthesis, biosynthesis of antibiotics, glyoxylate and dicarboxylate metabolism, and glycolysis/gluconeogenesis. Peroxidase7 was significantly upregulated and was selected and overexpressed in tobacco. Then, positive transgenic lines and wild type plants were exposed to a Cu stress environment. The results showed that Peroxidase7 transgenic tobacco plants exhibited enhanced Cu stress resistance with decreased malondialdehyde and Cu contents, and increased shoot dry weight, root length, secondary root number, SOD, POD and CAT activity. The present study suggests that the ROS scavenging mechanism is essential for tobacco plants in response to Cu stress and that Peroxidase7 functions in tobacco plant resistance to excessive Cu environment.
Some remarks on the assessment of P-wave velocity in laboratory tests for evaluating the degree of saturation
Authors: Astuto Giuseppe , Molina-Gómez Fausto , Bilotta Emilio , Viana da Fonseca António , Flora Alessandro
Published: July 2022

This work stems from the need to validate a technique for a reliably measurement of the degree of saturation (Sr) in deposits composed of sandy soils to improve their liquefaction resistance. The estimation of the degree of saturation of soil can be conducted by assessing the P-wave velocity (Vp), due to it values sharply increase near to the full saturation condition. P-wave measurements are comparable for in situ and laboratory procedures, offering prominent advantages for practical implementation. This paper presents a series laboratory results obtained from bender element tests conducted on a partially saturated monogranular sand. As a first approach, these tests were interpreted in the time-domain, showing how the interferences among the generated waves can significantly affect results and mask the actual degree of saturation in the specimen. However, a new processing of the output signal was carried out in the frequency-domain to accurate identify the wave propagation time. Moreover, results are discussed to investigate the mutual relationships between the Vp with Sr and Skempton’s B parameter. Finally, an experimental correlation between Vp and Sr is obtained, considering the strain level dependency of the soil behaviour, which can be adopted to interpret the results of in situ tests.

Published: July 2022

Fiber-reinforced composites have become the preferred material in the fields of aviation and aerospace because of their high-strength performance in unit weight. The composite components are manufactured by near net-shape and only require finishing operations to achieve final dimensional and assembly tolerances. Milling and grinding arise as the preferred choices because of their precision processing. Nevertheless, given their laminated, anisotropic, and heterogeneous nature, these materials are considered difficult-to-machine. As undesirable results and challenging breakthroughs, the surface damage and integrity of these materials is a research hotspot with important engineering significance. This review summarizes an up-to-date progress of the damage formation mechanisms and suppression strategies in milling and grinding for the fiber-reinforced composites reported in the literature. First, the formation mechanisms of milling damage, including delamination, burr, and tear, are analyzed. Second, the grinding mechanisms, covering material removal mechanism, thermal mechanical behavior, surface integrity, and damage, are discussed. Third, suppression strategies are reviewed systematically from the aspects of advanced cutting tools and technologies, including ultrasonic vibration-assisted machining, cryogenic cooling, minimum quantity lubrication (MQL), and tool optimization design. Ultrasonic vibration shows the greatest advantage of restraining machining force, which can be reduced by approximately 60% compared with conventional machining. Cryogenic cooling is the most effective method to reduce temperature with a maximum reduction of approximately 60%. MQL shows its advantages in terms of reducing friction coefficient, force, temperature, and tool wear. Finally, research gaps and future exploration directions are prospected, giving researchers opportunity to deepen specific aspects and explore new area for achieving high precision surface machining of fiber-reinforced composites.

A Spatial Perspective on the Unexpected Nordic Fertility Decline: The Relevance of Economic and Social Contexts
Authors: Campisi Nicholas , Kulu Hill , Mikolai Júlia , Klüsener Sebastian , Myrskylä Mikko
Published: July 2022

Since 2010, the Nordic countries have experienced substantial fertility decline. This was unexpected, as these countries have well-established systems of family support policies and they did not experience a fertility shock in the immediate aftermath of the 2008 economic recession like many other European countries. Previous studies paid little attention to the spatial dimension of this unexpected fertility change, despite evidence of large spatial variation in fertility. This paper aims to close this gap through a spatial perspective and deepen our understanding of how Nordic fertility change varies by economic and social contexts. We apply advanced spatial panel models on data for 1,099 municipalities covering Denmark, Finland, Norway, and Sweden. Next to analyzing total fertility rates, we also compare the relevance of economic and social contexts for spatial fertility variation at younger or older ages. We note distinct differences by levels of urbanization and differing trends between the age groups. We also find that measures of unemployment and union stability are associated with lower levels of fertility across space and time, while support for conservative parties is related to higher fertility. Age-specific analyses highlighted that economic conditions are more relevant for fertility variation under age thirty than over age thirty. Overall, our analysis provides support for the view that both economic and social factors are highly relevant for understanding spatial variation in the Nordic fertility decline. Given the strong spatial component in Nordic fertility change, policy initiatives would also benefit from a spatial dimension to effectively address fertility change.
The role of gender and coaching styles in adolescent student-athletes’ motivational orientations in sport and school
Authors: Saarinen Milla , Tolvanen Asko , Aunola Kaisa , Ryba Tatiana V.
Published: July 2022

Research indicates that the dominant discourses of gender are ingrained in dual career (DC) practices critically influencing athletes’ motivation to construct a DC pathway. While it is important to ensure that all athletes have an equal access to construct a DC pathway despite their gender, there is a gap in the literature examining the role that coaches play in gendering of athletes’ DC pathways. The present study longitudinally examined the gender differences in student-athletes’ motivational orientations in sport and academics throughout high school and the role of coaching style in these orientations. The gender differences in coaching styles in terms of student-athletes’ gender, coaches’ gender, and their interaction were also investigated. The sample consisted of 248 student-athletes from six upper secondary sport schools across Finland. The participants filled in questionnaires at the beginning of the first year and at the end of the third year of upper secondary sport school. The results showed that female student-athletes demonstrated higher levels of mastery orientation than males in both sport and school domains. Affective coaching style predicted male student-athletes’ mastery orientation in sport and both male and female student-athletes’ mastery orientation in school. Finally, female coaches were reported using more of an affective coaching style than male coaches. The results suggest that athletes benefit differently from an affective coaching style based on their gender and that it is beneficial to educate coaches how to use an affective coaching style with their DC athletes.
The Bodily Theory of Pain
Authors: Owesen Erlend Winderen Finke
Published: July 2022

One use of the noun ‘pain’ is exemplified in sentences like ‘There is a pain in my foot’. According to the Experiential Theory, ‘pain’ in this context refers to an experience located in the mind or brain. According to the Bodily Theory, it refers to an extra-cranial bodily occurrence located in a body part. In this paper, I defend the Bodily Theory. Specifically, I argue that pains are proximal activations of nociceptors that cause experiences of pain. This view is preferable to the Experiential Theory, because it accords better with common sense and offers a better interpretation or semantics of ordinary pain reports.
What are Automated Paraphrasing Tools and how do we address them? A review of a growing threat to academic integrity
Authors: Roe Jasper , Perkins Mike
Published: July 2022

This article reviews the literature surrounding the growing use of Automated Paraphrasing Tools (APTs) as a threat to educational integrity. In academia there is a technological arms-race occurring between the development of tools and techniques which facilitate violations of the principles of educational integrity, including text-based plagiarism, and methods for identifying such behaviors. APTs are part of this race, as they are a rapidly developing technology which can help writers transform words, phrases, and entire sentences and paragraphs at the click of a button. This article seeks to review the literature surrounding the history of APT use and the current understanding of APTs placed in the broader context of the educational integrity-technology arms race.

Net effects: examining strategies for women’s inclusion and influence in ASX200 company boards
Authors: Verhoeven Deb , Musial Katarzyna , Hambusch Gerhard , Ghannam Samir , Shashnov Mikhail
Published: July 2022

Conventional approaches to improving the representation of women on the boards of major companies typically focus on increasing the number of women appointed to these positions. We show that this strategy alone does not improve gender equity. Instead of relying on aggregate statistics (“headcounts”) to evaluate women’s inclusion, we use network analysis to identify and examine two types of influence in corporate board networks: local influence measured by degree centrality and global influence measured by betweenness centrality and k-core centrality. Comparing board membership data from Australia’s largest 200 listed companies in the ASX200 index in 2015 and 2018 respectively, we demonstrate that despite an increase in the number of women holding board seats during this time, their agency in terms of these network measures remains substantively unchanged. We argue that network analysis offers more nuanced approaches to measuring women’s inclusion in organizational networks and will facilitate more successful outcomes for gender diversity and equity.
Modelling Large-Scale Scientific Data Transfers
Authors: Bogado Joaquin , Lassnig Mario , Monticelli Fernando , Díaz Javier
Published: July 2022

This work focuses on the study of a recently published dataset (Bogado et al. in ATLAS Rucio transfers dataset. Zenodo, 2020.) with data that allow us to reconstruct the lifetime of file transfers in the contexts of the Worldwide LHC Computing Grid (WLCG). Several models for Rule Time To Complete (TTC) prediction are presented and evaluated. The dataset source is Rucio, an open-source software framework that provides scientific collaborations with the functionality to organize, manage, and access their data at scale. The rich amount of data gathered about the transfers and rules, presents a unique opportunity to better understand the complex mechanisms involved in file transfers across the WLCG.
Design and comparative analysis of active-loaded differential amplifier using double-gate MOSFET
Authors: Pillay Suvashan , Srivastava Viranjay M.
Published: July 2022

This research paper proposes the design of an active-loaded differential amplifier using the Double-Gate (DG) MOSFET. This differential amplifier employs feedback and simplifies a previously designed topology by reducing it to a single-ended output instead of a differential one. Other topologies have been referred to determine the benchmark of this design work. The DG MOSFET has been utilized for its high-frequency characteristics, Radio Frequency (RF) applications, and possible advantages in scalability. Electronic device simulation determines the technical feasibility of this differential amplifier using DG MOSFET. The designed differential amplifier exhibits a differential gain of 1.7–1.8 V/V and −3 dB cut-off frequency of 42 MHz. The amplifier can be used in various applications using this methodical design process and the circuital information.

Against a second factor
Authors: Sullivan-Bissett Ema
Published: July 2022

In his recent book Delusions and Beliefs, Kengo Miyazono offers a thoroughgoing defence of delusions as biologically malfunctioning beliefs, greatly elaborating on his earlier (2015) defence of this view. Miyazono has it that delusions have biological doxastic functions (i.e. functions specific to belief), and that delusions involve direct or indirect malfunctions of this kind. In this short piece, I focus on Miyazono’s defence of a two-factor approach to delusion formation as it appears in Chapter Four (Etiology). Miyazono approaches his discussion of the debate between one- and two-factor theories having already defended the key thesis of the book: that delusions are malfunctioning beliefs. Of course, that thesis might be thought to mesh nicely with the two-factor theorist’s claim that there is a cognitive abnormality present in delusion formation or maintenance. However, I will discuss Miyazono’s defence of the two-factor position in isolation from its role in his overall account of delusion. Miyazono abstracts away from the particulars of Max Coltheart’s two-factor view, and takes himself to be investigating the plausibility of two-factor theories without the specific commitments of Coltheart’s view (i.e. that the first factor of the Capgras delusion is not consciously accessible, and that the second factor is related to right hemisphere abnormalities). Miyazono also captures under the two-factor heading theories which locate the second factor in belief maintenance rather than just in belief formation. He puts forward a new argument for a two-factor approach which goes via inference to the best explanation. I begin by arguing that Miyazono’s starting motivation for a two-factor approach rests on a misrepresentation of the one-factor approach. Then, I turn to the four components of Miyazono’s inference to the best explanation argument, and argue that in each case, we do not have grounds for positing a second factor.
Nonreductive Group Knowledge Revisited
Authors: Kallestrup Jesper
Published: July 2022

A prominent question in social epistemology concerns the epistemic profile of groups. While inflationists and deflationists agree that groups are fit to constitute knowers, they disagree about whether group knowledge is reducible to knowledge of their individual members. This paper develops and defends a weak inflationist view according to which some, but not all, group knowledge is over and above any knowledge of their members. This view sits between the deflationist view that all group knowledge is reducible to individual knowledge, and the strong inflationist view that some such knowledge even fails to supervene on features of individuals. Thus, some group knowledge is irreducible, but all such knowledge is anchored in, and so doesn't float freely from, individual features.
Greed, Envy, and Admiration: The Distinct Nature of Public Opinion about Redistribution from the Rich
Authors: HANSEN KRISTINA JESSEN
Published: July 2022

Research on public opinion about economic redistribution has made important progress by incorporating the psychological microfoundation that shapes support for redistribution to the poor. However, one piece is missing: the microfoundation shaping support for redistribution from the rich. I provide a novel theory about this facet of redistributive attitudes and how it is distinct. Observational data from three nationally representative samples in two different welfare systems and an experiment show that attitudes about taking from the rich are mainly driven by perceptions of their prosociality—whether they are greedy or generous. This contrasts with public opinion about giving to the poor that is mainly driven by perceptions of the efforts of poor people. Furthermore, while compassion shapes attitudes about giving to the poor, the emotions of admiration and envy shape attitudes about taking from the rich. These findings have important theoretical and empirical implications for public opinion about economic redistribution.
The main component of the scent ofSenecio madagascariensisflowers is an attractant forAedes aegypti(L.) (Diptera: Culicidae) mosquitoes
Authors: Kashiwagi G. A. , von Oppen S. , Harburguer L. , González-Audino P.
Published: July 2022

Aedes aegypti(L.) (Diptera: Culicidae) is one of the main vectors of arboviruses, including dengue, Zika, and chikungunya. It almost exclusively inhabits urban areas. Both sexes feed on plant carbohydrates, although for males, this is their only food source. In the case of floral nectars, mosquitoes locate plant sugar sources assisted by volatile compounds. In this work, we found that the floral scent ofSenecio madagascariensiselicited a behavioral response in males; therefore, we focused on identifying the volatiles emitted by these flowers. The terpenes (±)-α-pinene, β-pinene, sabinene, and phellandrene and 1-alkenes 1-undecene, and 1-nonene were identified. To determine which compounds are bioactive, pure synthetic lures were assessed using an olfactometer. Only the main compound 1-nonene was an attractant for males. Since our goal was the introduction of synthetic floral-based attractants in toxic sugar-baited traps, we formulated 1-nonene in solid paraffin and stearin matrices to obtain a controlled release system. The bioassay with a toxicological end point showed that the incorporation of a feeding attractant to the toxic sugar trap increased overall mortality. These results suggest that it is possible to use plant volatile compounds or flower cuttings as maleAe. aegyptiattractants to improve the efficacy of baited traps.

HORACE, ODES 1.30
Authors: Kovacs David
Published: July 2022

This brief poem (Hor. Carm. 1.30) is by turns enigmatic (what is the purpose of Horace's prayer to Venus?) and slightly incoherent (why should both Horace and Glycera be praying to Venus? Are they praying for the same thing or for different things? Either has its problems). A further problem is that, if Horace intended uocantis in line 2 for a genitive, the text as it stands misleads the first-time reader, contrary to Horace's normal practice of authorial kindness toward such readers. The way to deal with this is to take uocantis as accusative (‘those calling on you with much incense’) and to insert an ‘and’ in the text to connect sperne and transfer: sperne dilectam Cypron et uocantīs | ture te multo  Glycerae decoram | transfer in aedem (‘reject your beloved Cyprus and your incense-offering devotees and move to Glycera's beautiful shrine’). If this is right, it addresses the incoherencies under which the usual interpretation labours.
Genetic gains in potato breeding as measured by field testing of cultivars released during the last 200 years in the Nordic Region of Europe
Authors: Ortiz Rodomiro , Reslow Fredrik , Cuevas Jaime , Crossa José
Published: July 2022

Genetic gains (ΔG) are determined by the breeders' equation ΔG = [(ck σ2G)/(y σP)], where c, k and y are the parental control, a function of the selection intensity and number of years to complete one selection cycle, respectively, while σ2G and are σP the genetic variance and the square root of the phenotypic variance. Plant breeding programs should deliver above 1% of annual genetic gains after testing and selection. The aim of this research was to estimate genetic gains in potato breeding after testing of cultivars released in western Europe in the last 200 years under high yield potential, and stress-prone environments affected by a pest (late blight) or daylength. The annual genetic gains for tuber yield and flesh's starch content for potato breeding in Europe were about 0.3 and −0.1%, respectively, thus telling that the realized genetic gains of foreign cultivars for both traits are small or negative, respectively, in the Nordic testing sites. The national annual productivity gains in potato grown in Sweden were on average 0.7% in the last 60 years while the genetic gains for tuber yield considering only the table cultivars released after the 2nd World War were about 0.36%, thus showing that breeding contributed just above ½ of it. Furthermore, genetic gains for breeding low reducing sugars in the tuber flesh, and high host plant resistance to late blight were small (<0.2% per year). These results highlight that genetic gains are small when testing bred germplasm outside their target population of environments.

Published: July 2022

Objective

To study unusual presentations of coronavirus-associated mucormycosis that are rarely seen in sinonasal mucormycosis cases.

Method

The data of 400 rhino-orbito-cerebral mucormycosis patients admitted to Sawai Man Singh Hospital, Jaipur, from May 2021 to June 2021, were retrospectively collected. The diagnosis of mucormycosis was made by histological examination of biopsy samples.

Results

Out of 400 patients, 62 had symptoms other than common symptoms of rhino-orbito-cerebral mucormycosis. Thirty-four patients had facial palsy, 19 complained of gum ulcers, 6 developed a cheek abscess, 2 complained of maggots in the nose along with common rhino-orbito-cerebral mucormycosis symptoms, and 1 had a cerebellar infarct.

Conclusion

Mucormycosis is a disease with various presentations, and coronavirus-associated mucormycosis has added unusual presentations to the existing list of manifestations of rhino-orbito-cerebral mucormycosis. In this coronavirus disease era, mucormycosis should always be considered as a diagnosis in patients with these unusual presentations.
First record of the barnacle Conchoderma virgatum on an ephippid fish
Authors: Mesaglio Thomas , Dowse Matt , McMartin Graham

The goose barnacle Conchoderma virgatum is a highly opportunistic epibiont, with observations of attachment to a wide range of marine organisms. Attachment to perciform fishes, however, is rarely observed. Observations of Conchoderma-osteichthyan associations in general are also rare in the southern hemisphere, especially in Australian waters. We present the first record of C. virgatum as an epibiont on an ephippid fish (Platax teira). This is also only the second known record of C. virgatum attached to a perciform fish in the Tasman Sea. We also summarize all previous known observations of C. virgatum in association with perciform fishes.
Antagonistic interactions among marine sedimentary bacteria in multispecies microcosms
Authors: Hook Whitney , Plante Craig
Published: July 2022

Antagonism among bacteria is widespread and plays an important role in structuring communities. Inhibitory compounds can confer competitive advantage, but energetic trade-offs can result in non-transitive (i.e. ‘rock-paper-scissors’) interactions, ultimately allowing co-existence and community stability. Competition in sedimentary habitats is especially keen given high densities and attachment to inorganic particles. Because measuring trade-offs between bacterial species is challenging, much of our understanding of competitive interactions is based on theoretical modelling and simplified in vitro experiments. Our objectives were to determine (1) if interference competition occurs in microcosms mimicking in situ conditions; (2) whether the presence of sediment influences antagonistic interactions; and (3) if more complex assemblages alleviate or synergize interactions. Four sedimentary isolates, including antibiotic-producing, resistant and susceptible strains were incubated in porewater microcosms in 1-, 2- and 3-species combinations, both with and without natural sediments. Microcosms were sampled over 72 h to generate growth curves using quantitative PCR. Multiple growth attributes (growth rate, maximum density, lag time) were used to assess effects of treatment (species combinations) and environment (sediment vs porewater alone). Antimicrobial producers were more effective at inhibiting target species in microcosms that included sediment, in agreement with theory. We observed growth inhibition by antimicrobial-producing bacteria in both 2- and 3-species microcosms. However, the expected protection of sensitive bacterial strains by resistant strains was observed in only one (of four) 3-species combinations, thus the ‘rock-paper-scissors’ prediction was not fully supported. These results reinforce the notion that interspecies interactions are context-dependent, reliant on environmental conditions and the species involved.

Background

Glutamatergic dysfunction has been implicated in sensory integration deficits in schizophrenia, yet how glutamatergic function contributes to behavioural impairments and neural activities of sensory integration remains unknown.

Methods

Fifty schizophrenia patients and 43 healthy controls completed behavioural assessments for sensory integration and underwent magnetic resonance spectroscopy (MRS) for measuring the anterior cingulate cortex (ACC) glutamate levels. The correlation between glutamate levels and behavioural sensory integration deficits was examined in each group. A subsample of 20 pairs of patients and controls further completed an audiovisual sensory integration functional magnetic resonance imaging (fMRI) task. Blood Oxygenation Level Dependent (BOLD) activation and task-dependent functional connectivity (FC) were assessed based on fMRI data. Full factorial analyses were performed to examine the Group-by-Glutamate Level interaction effects on fMRI measurements (group differences in correlation between glutamate levels and fMRI measurements) and the correlation between glutamate levels and fMRI measurements within each group.

Results

We found that schizophrenia patients exhibited impaired sensory integration which was positively correlated with ACC glutamate levels. Multimodal analyses showed significantly Group-by-Glutamate Level interaction effects on BOLD activation as well as task-dependent FC in a ‘cortico-subcortical-cortical’ network (including medial frontal gyrus, precuneus, ACC, middle cingulate gyrus, thalamus and caudate) with positive correlations in patients and negative in controls.

Conclusions

Our findings indicate that ACC glutamate influences neural activities in a large-scale network during sensory integration, but the effects have opposite directionality between schizophrenia patients and healthy people. This implicates the crucial role of glutamatergic system in sensory integration processing in schizophrenia.
Life Course Predictors of Young Men Surviving to Age 90 in a Cohort Study: The Manitoba Follow-up Study

Published: July 2022

The purpose of this study was to identify factors at various time points in life that are associated with surviving to age 90. Data from men enrolled in a cohort study since 1948 were considered in 12-year intervals. Logistic regression models were constructed with the outcome of surviving to age 90. Factors were: childhood illness, blood pressure (BP), body mass index (BMI), chronic diseases, and electrocardiogram (ECG) findings. After 1996, the Short Form-36 was added. A total of 3,976 men were born in 1928 or earlier, and hence by the end of our study window in 2018, each had the opportunity of surviving to age 90. Of these, 721 did live to beyond his 90th birthday.The factors in 1948 which predicted surviving were: lower diastolic BP, lower BMI, and not smoking. In 1960, these factors were: lower BP, lower BMI, not smoking, and no major ECG changes. In 1972, these factors were lower BP, not smoking, and fewer disease states. In 1984, these factors were lower systolic BP, not smoking, ECG changes, and fewer disease states. In 1996, the factors were fewer disease states and higher physical and mental health functioning. In 2008, only higher physical functioning predicted survival to the age of 90. In young adulthood, risk factors are important predictors of surviving to age 90; in mid-life, chronic illnesses emerge, and in later life, functional status becomes predominant.
Down from the roof: reframing plants in Augustan art
Authors: Crawford-Brown Sophie
Published: July 2022

The Augustan marble “revolution” marked more than the substitution of one building material for another. It changed Rome's color, texture, and light, and visually redefined its sacred architecture. For centuries, temples in and around Rome had been decorated with brightly painted architectural terracottas, which typically featured a swirling array of plants and flowers. Terracotta was the material of sacred tradition, and the vegetal motifs employed on temples evoked a pious Italic past. The lush array of plant life present in Augustan art has not been adequately considered against this background. This paper explores the use of traditional plant motifs in Augustan art and architecture, with an emphasis on viewer response. It considers the so-called Campana reliefs before turning to a more detailed analysis of the Ara Pacis's vegetal panels. These, I argue, consciously evoked ancient temple decoration and drew it into the new visual language of the Augustan Principate.
How do you solve a problem like the city?
Authors: Dufton J. Andrew
Published: July 2022

The ebbs and flows of archaeological scholarship often see trends come and go, with big questions giving way to more fine-grained analysis only to, in turn, feed back into new, sweeping narratives. Thinking about the ancient city is no exception. Recent works from across the spectrum of archaeology and ancient history show a desire to draw new connections amongst urban sites in the same region, to explore similarities between regions, and even to interrogate the extent of similarity between settlements of drastically different periods and places.
Partially unroofed coronary sinus in an infant with pulmonary vein stenosis: mixed blessing
Authors: Mohammad Nijres Bassel , Stopak Joshua K. , Carr Kaitlin , Aldoss Osamah
Published: July 2022

Transcatheter intervention on the pulmonary vein often requires performing transseptal puncture, which is a risky procedure. We describe a rare association of a partially unroofed coronary sinus with pulmonary vein stenosis causing desaturation in a young infant where the presence of the unroofed coronary sinus allowed for a novel interventional approach to the stenotic left pulmonary vein, avoiding the high risk of transseptal puncture.

The Astrobiology Graduate Conference (AbGradCon) is an annual conference both organized for and by early-career researchers, postdoctoral fellows, and students as a way to train the next generation of astrobiologists and develop a robust network of cohorts moving forward. AbGradCon 2021 was held virtually on 14–17 September 2021, hosted by the Earth-Life Science Institute (ELSI) of Tokyo Institute of Technology after postponement of the in-person event in 2020 due to the COVID-19 pandemic. The meeting consisted of presentations by 120 participants from a variety of fields, two keynote speakers, and other career-building events and workshops. Here, we report on the organizational and executional aspects of AbGradCon 2021, including the meeting participant demographics, various digital aspects introduced specifically for a virtual edition of the meeting, and the abstract submission and evaluation process. The abstract evaluation process of AbGradCon 2021 is unique in that all evaluations are done by the peers of the applicants, and as astrobiology is inherently a broad discipline, the abstract evaluation process revealed a number of trends related to multidisciplinarity of the astrobiology field. We believe that meetings like AbGradCon can provide a unique opportunity for students and early career researchers in astrobiology to experience community building, inter- and multidisciplinary collaboration, and career training and would be a welcome sight in other fields as well. We hope that this report provides inspiration and a basic roadmap for organizing future conferences in any field with similar goals.
