Linguistic Cleavages in Canadian Political Science: Evidence from the Discipline's Annual Conference
Authors: Brie Evelyne , Daoust Jean-François 
Published: September 2024

AbstractAcademics across Canada, an officially bilingual and multicultural country, devote a lot of attention to diversity and representation. This is particularly true for political scientists. In this research note, we focus on the linguistic composition of panels and overall linguistic fragmentation of the most important in-person event for Canadian political science: the annual meeting of the Canadian Political Science Association (CPSA). To do so, we generated a dataset based on the official program of the 2023 annual conference. Our main results are twofold. First, we find an important under-representation of French-speaking events and academic communications (i.e., panels and papers). Second, we computed Herfindahl-Hirschman indexes demonstrating that francophone-dominated panels and co-authored papers with francophone first authors are significantly more linguistically diverse than anglophone panels and papers. Our results highlight important blind spots in Canadian political science and help make sense of the lack of representation of French-language work in Canadian academia.
Effects of Analog Modeling Materials on Topographic Photogrammetry (SfM) Reconstructions
Authors: Cawood Adam J. , Wyrick Danielle Y. 
Published: September 2024

AbstractAccurate topographic data are essential for quantitative structural analysis, both in natural settings and in the laboratory. The selection of modeling materials (with appropriate rheological properties) is known to be fundamental for the success of scaled physical analog experiments. However, the optical properties of analog materials and their impact on the reliability and precision of high‐resolution topographic reconstructions have not (to our knowledge) previously been assessed. Here we evaluate the effects of material composition, color, and grain size on Structure‐from‐Motion (SfM) photogrammetry reconstruction efficacy for deformed and undeformed model configurations in the laboratory. Image collections for photogrammetry are acquired from multiple camera positions with a handheld digital camera, and reconstructions are registered using ground control points in a local coordinate system. Static experiments show that low reflectivity granular materials (e.g., silica sand, volcanic ash, pumice, and Al2O3) yield relatively reliable photogrammetry data for a wide range of grain sizes (44–2,400 μm) but larger grain sizes (≥250 μm) provide more robust results. Reflective materials (e.g., glass beads, wet clay) yield less reliable point‐clouds but the addition of low‐reflectivity granular materials (e.g., Al2O3 grains) on the surface of wet clay improves reconstruction results, with higher grain densities typically yielding lower point‐cloud residuals. SfM‐photogrammetry reconstruction of deformed clay analog models tends to improve at higher extension magnitudes because of fault and associated texture development on model surfaces. We anticipate that our results will help practitioners to improve the precision and reliability of photogrammetric data acquired in the analog modeling laboratory.
Dependence of Simulated Fault Gouge Frictional Behavior on Mineral Surface Chemistry Quantified by Cation Exchange Capacity
Authors: Ikari Matt J. , Conin Marianne 
Published: September 2024

AbstractThe slip behavior of crustal faults is known to be controlled by the composition of the fault gouge, but the exact mechanisms, especially considering the role of water‐rock interactions, are still under investigation. Here, we use a geochemical approach measuring the cation exchange capacity (CEC) of several phyllosilicate minerals and non‐clays, using CEC as a proxy for the ability to bind water to the mineral surfaces and/or develop electrostatic forces between particles. Laboratory shearing experiments show that low CEC materials (<3 mEq/100 g) tend to exhibit high friction, low cohesion, and velocity‐weakening frictional behavior. Phyllosilicate minerals exhibit CEC values up to 78 mEq/100 g and correspondingly lower friction coefficients, higher cohesion, and a tendency for velocity‐strengthening friction. Zeolite behavior is atypical, exhibiting a high CEC value typical of phyllosilicates but the strength and frictional characteristics of a non‐clay with low CEC. This suggests that the structure of the mineral is important for non‐phyllosilicates. For phyllosilicates, our results can be explained by water bound to mineral surfaces, creating bridges of hydrogen or van der Waals bonds between particles. The enhanced particle bonding for high CEC materials is consistent with high cohesion under zero effective stress conditions, and lowered friction by trapping bound water between the mineral surfaces under normal load. Bound water may explain the tendency for velocity‐strengthening friction in high CEC materials by hindering a Dieterich‐type time‐dependent frictional strengthening mechanism.

AbstractThe paucity of fine particulate matter (PM2.5) measurements limits estimates of air pollution mortality in Sub‐Saharan Africa. Well calibrated low‐cost sensors can provide reliable data especially where reference monitors are unavailable. We evaluate the performance of Clarity Node‐S PM monitors against a Tapered element oscillating microbalance (TEOM) 1400a and develop a calibration model in Mombasa, Kenya's second largest city. As‐reported Clarity Node‐S data from January 2023 through April 2023 was moderately correlated with the TEOM‐1400a measurements (R2 = 0.61) and exhibited a mean absolute error (MAE) of 7.03 μg m−3. Employing three calibration models, namely, multiple linear regression (MLR), Gaussian mixture regression and random forest (RF) decreased the MAE to 4.28, 3.93, and 4.40 μg m−3 respectively. The R2 value improved to 0.63 for the MLR model but all other models registered a decrease (R2 = 0.44 and 0.60 respectively). Applying the correction factor to a five‐sensor network in Mombasa that was operated between July 2021 and July 2022 gave insights to the air quality in the city. The average daily concentrations of PM2.5 within the city ranged from 12 to 18 μg m−3. The concentrations exceeded the WHO daily PM2.5 limits more than 50% of the time, in particular at the sites nearby frequent industrial activity. Higher averages were observed during the dry and cold seasons and during early morning and evening periods of high activity. These results represent some of the first air quality monitoring measurements in Mombasa and highlight the need for more study.

Published: September 2024

AbstractPrior research extensively investigates the delayed influence of El Niño‐Southern Oscillation (ENSO) events on subsequent summer climates, with persistent sea surface temperature anomalies (SSTAs) in remote tropical oceans serving as crucial pathways. This study unveils a previously overlooked midlatitude pathway. During the developing winter, El Niño events induce basin‐scale cold SSTAs in the central North Pacific, which can persist into the following summer. These anomalies significantly influence early‐summer atmospheric circulation by enhancing atmospheric baroclinicity and transient eddy activities. Primarily driven by transient eddy vorticity forcing, an equivalent barotropic geopotential low anomaly emerges over the North Pacific. Enhanced by the southwesterly winds of the atmospheric low, tropical moisture is transported farther northeastward in the early summer, resulting in increased rainfall in the Pacific Northwest region. By elucidating this meridional pathway, our study advances the understanding of ENSO's delayed impacts and associated dynamical processes, in which the midlatitude oceanic feedbacks are emphasized.
Whistler Waves and Two‐Stream Instabilities at Non‐Stationary Quasi‐Perpendicular Collisionless Shocks
Authors: Comişel Horia , Marghitu Octav 
Published: September 2024

AbstractUpstream propagating waves are observed to correlate with the reflected ions in the foot of a high Mach number quasi‐perpendicular collisionless shock. The respective wavefronts show time varying amplitude matching the variation of the reflected ions and the shock reformation cycles. We interpret this process in terms of the fast two‐stream instability and investigate the results of the PIC simulation as compared with the prediction of the linear analysis. Evidence for upstream propagating whistler waves supported by two‐stream instability is continuously growing, see for example, recent surveys based on MMS in‐situ observations of the Earth bow‐shock. The present study suggests that upstream propagating waves are consistent with and in particular supported by the mechanism of fast two‐stream instability developing in the upstream region of the shock foot.
Seasonal Variations in the Barrier Layer and Its Formation Mechanism in the Northern Indian Ocean
Authors: Liu Ying , Yan You‐Fang 
Published: September 2024

AbstractUnderstanding the impact of the ocean barrier layer (BL) on regional ocean dynamics requires the knowledge of BL variability and the factors influencing it. Herein, using SODA reanalysis data sets, we systematically investigate the seasonal variations and formation mechanisms of BLs in the North Indian Ocean (NIO). Our results show that BLs are mainly found in the southeastern Arabian Sea (SEAS), Bay of Bengal (BoB), and the Eastern Equatorial Indian Ocean (EEIO), with the thickest BLs occurring in SEAS and BoB in January, and in EEIO in November. Seasonal BL variability is primarily driven by isothermal layer (IL) modulation. Further budget analysis reveals that the factors affecting seasonality of BL variability through modulating IL differ across the three regions. In the SEAS, BL variability is primarily modulated by ocean vertical processes, notably oceanic planetary waves and Ekman pumping. In the BoB, vertical dynamics, including Ekman pumping and oceanic planetary waves, are the primary determinant of BL variability, while horizontal advection affects the spatial extent of BL. In the EEIO, equatorial upwelling and oceanic planetary waves significantly affect BL variability. These results contribute to a better understanding of regional ocean dynamics and may improve the accuracy of ocean state estimates and representation of BL processes using ocean model simulations.
The association of fetal growth rate and growth in first year of life with childhood overweight: a cohort study
Authors: Leth-Møller Magnus , Kampmann Ulla , Hede Susanne , Ovesen Per G. , Hulman Adam , Knorr Sine 
Published: September 2024

Abstract
Background
There is an increasing focus on the first 1000 days from conception to two years of age as a period of importance for future weight. We aimed to describe the interaction between fetal and infant growth and their association with and ability to predict childhood overweight.

Methods
We used routinely collected fetal growth data from Aarhus University Hospital and child growth data from Aarhus Municipality, 2008–2018. The outcome was overweight at age 5–9 years. The fetal growth rates at weeks 28 and 34 were extracted from individual trajectories using mixed models. We identified patterns of infant BMI Z-score growth using latent class analysis and estimated odds ratios of overweight at age 5–9 years dependent on fetal and infant growth. Predictive capabilities were assessed by comparing areas under the ROC-curves (AUCROC) of the prediction models.

Results
In 6206 children, we identified three infancy growth patterns: average, accelerated, and decelerated growth. We found 1.09 (95% CI: 1.06–1.12) greater odds of being overweight for every 10 g/week increase in fetal growth rate at week 34. Compared with average growth, accelerated infant growth was associated with 1.52 (95% CI: 1.20–1.90) greater odds of overweight. Combining fetal and infant growth, children with average fetal growth and accelerated infant growth had 1.96 (95% CI: 1.41–2.73) greater odds of overweight. Fast fetal growth with decelerated infant growth was not associated with being overweight (OR: 0.79 (95% CI: 0.63–0.98)), showing that infant growth modified the association between fetal growth and overweight. When fetal growth was added to a prediction model containing known risk factors, the AUCROC remained unchanged but infant growth improved the predictive capability (AUCROC difference: 0.04 (95% CI: 0.03–0.06)).

Conclusion
Fetal and infant growth were independently associated with overweight, but distinct combinations of fetal and infant growth showed marked differences in risk. Infant, but not fetal, growth improved a prediction model containing known confounders.

AbstractImmunological aetiology is supported for a subgroup with obsessive compulsive disorder (OCD) and conceptualized as autoimmune OCD. The longitudinal clinical course is detailed for three severely ill cases with OCD and indications of immunological involvement with off-label rituximab treatment every six months. All cases showed clear and sustained gains regarding symptom burden and function for over 2.5 years. Brief Psychiatric Rating Scale and Yale-Brown Obsessive-Compulsive Inventory Scale scores decreased 67-100% and 44-92%, respectively. These complex cases, prior to rituximab, had very low functioning and disease duration has been eight, nine and 16 years respectively. All three patients had been unsuccessfully treated with at least two antidepressants or anxiolytics, one neuroleptic and cognitive behavioural therapy. Clinical phenotypes and findings were suggestive of possible autoimmune OCD. Indirect immunohistochemistry detected cerebral spinal fluid (CSF) antibodies in all three cases including a novel anti-neuronal staining pattern against mouse thalamic cells. Exploratory analyses of CSF markers and proteomics identified elevated levels of sCD27 and markers indicative of complement pathway activation when compared to CSF from healthy controls. Multidisciplinary collaboration, advanced clinical investigations and rituximab treatment are feasible in a psychiatric setting. The case histories provide a proof of principle for the newly proposed criteria for autoimmune OCD. The findings suggest that clinical red flags and biological measures may predict rituximab response in chronic treatment-resistant OCD. The report provides orientation that may inform the hypotheses and design of future treatment trials.
Expanding the horizon of continuous glucose monitoring into the future of pediatric medicine
Authors: Morales-Dopico Lourdes , MacLeish Sarah A. 
Published: September 2024

Abstract
Glucose monitoring has rapidly evolved with the development of minimally invasive continuous glucose monitoring (CGM) using interstitial fluid. It is recommended as standard of care in the ambulatory setting, nearly replacing capillary glucose testing in those with access to CGM. The newest CGM devices continue to be smaller and more accurate, and integration with automated insulin delivery systems has further revolutionized the management of diabetes, leading to successful improvements in care and quality of life. Many studies confirm accuracy and application of CGM in various adult inpatient settings. Studies in adult patients increased during the COVID 19 Pandemic, but despite reassuring results, inpatient CGM use is not yet approved by the FDA. There is a lack of studies in inpatient pediatric settings, although data from the NICU and PICU have started to emerge. Given the exponential increase in the use of CGM, it is imperative that hospitals develop protocols for CGM use, with a need for ongoing implementation research. In this review we describe how CGM systems work, discuss benefits and barriers, summarize research in inpatient pediatric CGM use, explore gaps in research design along with emerging recommendations for inpatient use, and discuss overall CGM utility beyond outpatient diabetes management.

Impact

Current CGM systems allow for uninterrupted monitoring of interstitial glucose excursions, and have triggered multiple innovations including automated insulin delivery.

CGM technology has become part of standard of care for outpatient diabetes management, endorsed by many international medical societies, now with significant uptake, replacing capillary glucose testing for daily management in patients with access to CGM technology.

Although CGM is not approved by the FDA for inpatient hospital use, studies in adult settings support its use in hospitals. More studies are needed for pediatrics.

Implementation research is paramount to expand the role of CGM in the inpatient setting and beyond.

Abstract
With the rapid increase in power density of electronic devices, thermal management has become urgent for the electronics industry. Controlling temperature in the back-end-of-line is crucial for maintaining the reliability of integrated circuits, where many atomic-scale interfaces exist. The theoretical models of interface thermal conductance not only accurately predict the values but also help to analyze the underlying mechanism. This review picks up and introduces some representative theoretical models considering interfacial roughness, elastic and inelastic processes, and electron–phonon couplings, etc. Moreover, the limitations and problems of these models are also discussed.

Published: September 2024

Abstract

Design
An observational cohort study conducted at a tertiary referral center for aortic surgery to describe the medical and surgical characteristics of patients assessed for abdominal aortic aneurysm repair and examine associations with 12-month outcome.

Methods
Patients with aortic aneurysms referred for discussion at the aortic multidisciplinary meeting (MDM). Data were collected via a prospectively maintained clinical database and included aneurysm characteristics, patient demographics, co-morbidities, geriatric syndromes, including frailty, management decision and 12-month mortality, both aneurysm-related and all-cause including cause of death. The operative and non-operative groups were compared statistically.

Results
621 patients referred to aortic MDM; 292 patients listed for operative management, 141 patients continued on surveillance, 138 patients for non-operative management. There was a higher 12-month mortality rate in the non-operative group compared to the operative group (41% vs 7%, P = &lt;0.001). In the non-operative group, 16 patients (29%) died of aneurysm rupture within 12 months, with 39 patients (71%) dying from other medical causes. Non-operatively managed patients were older, more likely to have cardiac and respiratory disease and more likely to be living with frailty, cognitive impairment and functional limitation, compared to the operative group.

Conclusion
This study shows that preoperative geriatric syndromes and increased comorbidity lead to shared decision to non-operatively manage asymptomatic aortic aneurysms. Twelve-month mortality is higher in the non-operative group with the majority of deaths occurring due to cause other than aneurysm rupture. These findings support the need for preoperative comprehensive geriatric assessment followed by multispecialty discussion and shared decision making.
FDP-FL: differentially private federated learning with flexible privacy budget allocation

Published: September 2024

Abstract
Federated learning (FL) as a privacy-preserving technology enables multiple clients to collaboratively train models on decentralized data. However, transmitting model parameters between local clients and the central server can potentially result in information leakage. Differentially private federated learning (DPFL) has emerged as a promising solution to enhance privacy. Nevertheless, existing DPFL schemes suffer from two issues: (i) most schemes that aim to achieve desired model accuracy may incur a high privacy budget. (ii) several schemes that consider the trade-off between privacy and accuracy by utilizing linear clipping bound may distort numerous model parameters. In this paper, we first propose FDP-FL, a flexible differential privacy approach for FL. FDP-FL introduces a novel series sum privacy budget allocation instead of uniform allocation and enables adaptive and nonlinear noise scale decay. In this way, a tight bound for cumulative privacy loss can be achieved while optimizing model accuracy. Then in order to mitigate gradient leakages caused by honest-but-curious clients and server, we further design client-level FDP-FL and record-level FDP-FL, respectively. Experimental results demonstrate that our FDP-FL improves model accuracy by $\sim $13.3% compared with the basic DP-FL under a fixed privacy budget and outperforms existing trade-off schemes with the same hyperparameter setting.

Published: September 2024

Abstract
With the development of the fourth industrial revolution, the importance of data centers has significantly increased. Data centers are widely used in many fields due to their ability to provide efficient, secure, and reliable data storage and processing services. However, with the increasing amount of data, traditional data center networks (DCNs) are currently facing various challenges, prompting academia and industry to propose new DCN architectures. As a dual-port server-based DCN, DPCell has excellent scalability and bisection width, enabling it to meet the demands of large-scale data storage, processing, and computation in the digital revolution. In order to ensure the secure and reliable data communication in the DPCell, this paper designs a disjoint paths communication scheme based on the actual DCN routing requirements. This scheme constructs the optimal number of disjoint paths in DPCell, with a maximum path length of $2^{k}+3$, where $k$ represents the dimension of the DPCell. Furthermore, experiments have verified that the time complexity of this scheme is sublinear, making it more efficient than the current optimal maximum flow algorithm. To a certain extent, this scheme provides DPCell with the required high bandwidth, fault tolerance, and security for data communication.
