Review and prospect of soil compound erosion
Authors: Yang Wenqian , Zhang Gangfeng , Yang Huimin , Lin Degen , Shi Peijun
Published: October 2023

Soil erosion is one of the most serious environmental issues constraining the sustainable development of human society and economies. Soil compound erosion is the result of the alternation or interaction between two or more erosion forces. In recent years, fluctuations and extreme changes in climatic factors (air temperature, precipitation, wind speed, etc.) have led to an increase in the intensity and extent of compound erosion, which is increasingly considered in soil erosion research. First, depending on the involvement of gravity, compound erosion process can be divided into compound erosion with and without gravity. We systematically summarized the research on the mechanisms and processes of alternating or interacting soil erosion forces (wind, water, and freeze-thaw) considering different combinations, combed the characteristics of compound erosion in three typical regions, namely, high-elevation areas, high-latitude areas, and dry and wet transition regions, and reviewed soil compound erosion research methods, such as station observations, simulation experiments, prediction models, and artificial neural networks. The soil erosion model of wind, water, and freeze-thaw interaction is the most significant method for quantifying and predicting compound erosion. Furthermore, it is proposed that there are several issues such as unclear internal mechanisms, lack of comprehensive prediction models, and insufficient scale conversion methods in soil compound erosion research. It is also suggested that future soil compound erosion mechanism research should prioritize the coupling of compound erosion forces and climate change.

Authors: Ortakaya Ülkü İstiklal
Published: October 2023

The present qualitative study attempted to elicit the working poor’s views on the social assistance system in Türkiye. We held in-depth interviews with 30 conveniently selected participants between March and June 2022 in Ankara and analyzed the findings descriptively. Accordingly, the results highlighted the working poor’s experiences with the social assistance system, the role of this system in their employment, and their expectations of the system. In a nutshell, our findings implied that the working poor should be granted minimum income support to improve the efficiency of the Turkish social assistance system further in combating in-work poverty.
Seismic response of granites with different grain sizes after thermal treatment: an experimental study
Authors: Zhou Erkang , Zhai Tianqi , Zhu Jianbo
Published: October 2023

Understanding the wave propagation behaviour in rock masses with different temperatures and geological conditions is of great significance for the stability and safety evaluation of deep rock engineering, e.g., enhanced geothermal system, nuclear waste disposal. However, the response and mechanism of ultrasonic waves through granites after thermal treatment are still poorly understood. In order to determine the combined effects of heating temperature and grain size on wave propagation across granites, a series of laboratory ultrasonic tests were performed with the pulse transmission method, combined with scanning electron microscopy observation. The testing results indicate that heating temperature and grain size have a combined impact on wave propagation across the tested granites. The wave velocity, transmitted coefficient, peak power spectral density and accumulative energy are generally negatively correlated with heating temperature regardless of grain size. The effect of grain size on wave propagation is more pronounced at low temperatures. Basically, the crack evolution is the main reason for the seismic response of granite after thermal treatment. A damage factor defined by the change of microcrack area in this paper is proposed and adopted to consider the combined effect of heating temperature and grain size. The peak power spectral density of the low-frequency wave and the transmission coefficient of the high-frequency wave are appropriate as the optimal wave indicators for evaluating the deterioration of granites at high- and low-damage stages, respectively. The findings in this study are of great importance for site selection and stability assessment in rock engineering activities under high temperatures, especially for the development of deep-seated hot dry rock.

Published: October 2023

Ventilation door are commonly found in tunnels and other underground engineering ventilation structures, disaster periods using its explosion isolation, explosion relief, wind regulation characteristics for disaster prevention and mitigation is of great significance. This paper numerically simulates the propagation characteristics of the gas explosion shock wave in the nearby tunnel when the ventilation door are opened at different degrees, and analyzes the influence mechanism of the opening degree on the change law of the shock wave overpressure distribution in the nearby tunnel. The results show that the shock wave forms a strong turbulence area (high pressure area) on both sides in front of the ventilation door, and the area range and the overpressure value decrease with the increase of the opening degree; the ventilation door reduce the intensity of the shock wave, so that the overpressure behind the ventilation door decreases, and the smaller the opening degree, the lower the overpressure behind the ventilation door. The secondary explosion formed shock wave and the ventilation door reflected shock wave meet to form a stronger shock wave, which leads to different opening degrees of ventilation door, its before, after the roadway and after the bifurcation of the main roadway in the measured points of the overpressure change curve is different, the main difference is that the peak overpressure for the first wave or the second wave peak. The peak overpressure in the tunnel before and after the ventilation door decreases and increases respectively with the increase of the opening length, and the overall decay of the peak overpressure at 5 m and 10 m before the ventilation door is 49.56% and 4.04% respectively and only has an effect on the peak overpressure in main tunnel within 20 m from the bifurcation.

Published: October 2023

This study investigates the effects of 3D printing parameters on the mechanical properties (predominantly tensile properties) of a commercial polylactic acid-based wood fiber composite material known as wood filament. The influence of printing parameters, including layer thickness, infill density, printing speed, and nozzle temperature on the mechanical properties, is studied, and the design of the experiment (DOE) is made through Taguchi L9 orthogonal array. The specimens for the tensile test are fabricated by the material extrusion (MEX) 3D printer, which is also known as fused deposition modeling (FDM) or fused filament fabrication (FFF). After conducting the tensile test, this research considers four significant outcomes: tensile strength, maximum load, elastic modulus, and elongation at break. Further analysis of the obtained results from mechanical testing is performed through analysis of variance (ANOVA) to determine the significance of each parameter on the mechanical properties. Moreover, prediction and optimization are conducted to verify the obtained results from the DOE. Furthermore, scanning electronic microscopy (SEM) is used to analyze the fracture zones, cracks, voids, and fiber/matrix adhesion of the FDM fabricated parts which demonstrates that the lower layer thickness provides better adhesion and fewer voids between successive layers and thus exhibits better mechanical performance.

Postplagiarism: transdisciplinary ethics and integrity in the age of artificial intelligence and neurotechnology
Authors: Eaton Sarah Elaine
Published: October 2023

In this article I explore the concept of postplagiarism, loosely defined as an era in human society and culture in which advanced technologies such as artificial intelligence and neurotechnology, including brain-computer interfaces (BCIs), become a normal part of life, including how we teach, learn, communicate, and interact on a daily basis. Ethics and integrity are intensely important in the postplagiarism era when technology cannot be decoupled from everyday life. I argue that it might be reasonable to assume that when commercialized neuro-educational technology is readily available in a form that is implantable/ingestible/embeddable and invisible then academic integrity arms race will be over, as detection will be an exercise in futility.

In a postplagiarism era, humans are compelled to grapple with questions about ethics and integrity for a socially just world at a time when advanced technology cannot be unbundled from education or everyday life. I conclude with a call to action for transdisciplinary research to better understand ethical implications of advanced technologies in education, emphasizing that such research can be considered pre-emptive, rather than speculative. The ethical implications of ubiquitous artificial intelligence and neurotechnology (e.g., BCIs) in education are important at a global scale as we prepare today’s students for academic and lifelong success.
Enterprise Informality in India: The Blind Spots in Public Policy
Authors: Mehrotra Santosh , Giri Tuhinsubhra
Published: October 2023

An essential characteristic of firm size distribution patterns in developing countries including India, is a bimodal distribution with a “missing middle”, which is widely accepted in development economics. We analyse data from the Annual Survey of Industries (ASI), National Sample Survey (NSS) and Economic Census to assess the firm size structure of the whole non-farm sector. The contribution of the paper is that for the first time a comprehensive database is constructed to enable analysis of the size structure of India’s non-farm enterprises. The second contribution is that we find a deep distortion in India, with even a “small”-scale sector being very small, relatively. We examine briefly the policy-related causes that make India an outlier even among Asian economies in respect of size structure of enterprises. Finally, we argue that the historically policy-induced informality of enterprises is being entrenched by the current hiatus in state policy in even recognising the true nature of the problem of micro, small & medium enterprises (MSMEs), which holds back both their growth and employment.
The flexural response of RC beams strengthened by EB/NSM techniques using FRP and metal materials: a state-of-the-art review
Authors: Megahed F. A. , Seleem M. H. , Badawy A. A. M. , Sharaky I. A.
Published: October 2023

Reinforced concrete (RC) beams strengthened in flexure using externally bonded (EB) or near-surface mounted (NSM) fiber-Reinforced Polymers (FRP) and metals have gained considerable interest over the last few decades. As few of the previous review papers concerned with NSM elements or both EB and NSM methods so this paper aimed to review the previous research that handled the behavior of RC beams strengthened by NSM and EB techniques, compared their advantages and disadvantages and reported the future recommendations. Moreover, the review focused on the effect of strengthening materials (metallic and FRP materials), strengthening method, strengthening elements characteristics (shape and area), and any other factors affecting the performance of the strengthened RC beams in each technique. The review demonstrated that the strengthening element’s failure mode significantly affects the RC beams’ load-carrying capacity strengthened by EB or NSM. Moreover, the type of FRP materials and the end anchorage significantly affect the load efficiency of the strengthened RC beams depending on the type of failure mode.
Revealing enhanced X-Ray radiation shielding of 2D layered materials and their laminar heterostructures

Published: October 2023

This paper demonstrates a new concept of using two-dimensional (2D) layered materials and their heterostructures for enhanced X-ray radiation shielding. This phenomenon is revealed by characterization on the X-ray shielding performances of several 2D materials with high atomic numbers (Z), including MoS2, antimonene (Sb), and MXene prepared as multi-layered and heterostructure films by assembly their few-layer sheets. Results showed considerable X-ray shielding enhancement of (40–50%) at 30 kVp for individual 2D multi-layered films compared with their bulk structures of these materials. Furthermore, when these multi-layered films were combined into laminar heterostructures structures (e.g., MoS2 + MXene), further enhancement of 60% was achieved. The mechanism of the observed X-ray shielding enhancement by these multi-layered 2D structures is not clear at this stage. It is postulated to be the result of an additional multiple scattering and reflections of photons between multiple layers of 2D crystals inside the film, which does not occur in their uniform bulk materials. The presented results suggest that multi-layered 2D materials with high atomic numbers (Z) and their laminar heterostructures could offer a new and promising strategy for designing of a new generation of Pb-free radiation-shielding materials, which is urgently needed across broad sectors.

From Coupling Second-Order Stresses to Understanding and Predicting the Structural Response of a Dioctahedral Smectite
Authors: Mejri Chadha , Oueslati Walid , Ben Haj Amara Abdesslem
Published: October 2023

The employment of clay minerals in the transport of water, nutrients, and contaminants depends on a few factors, including permeability, hydration behavior, ion-exchange efficiency, and more. With the application of external stress, it is still difficult to understand how clay particles swell and collapse, how water is retained, how hydration heterogeneities are formed within crystallites, and how interlamellar space is organized. The present work studied the link between geochemical, thermal, kinetic constraints (established at the laboratory scale), and intrinsic clay features by exchanging Na-rich montmorillonite (SWy2) with Ni2+, Mg2+, or Zn2+ cations. By comparing the experimental 00l reflections with the calculated reflections obtained from the structural models, quantitative X-ray diffraction (XRD) analysis has enabled the building of a theoretical profile describing the layer stacking mode (LSM) and allowed the description of interlayer space (IS) configuration along the c* axis. Regardless of the type of the exchangeable cations (EC), XRD modeling revealed that all samples exhibited interstratified hydration behavior within the crystallite size, which probably indicates partial or incomplete saturation of the IS. This theoretical result was defined by the appearance of two hydration states (1W and 2W), which were unrelated to the strain strength creating a higher degree of structural heterogeneity. Using the theoretical decomposition of the observed XRD patterns, the identification of all distinct layer populations and their stacking mode was achieved. The segregated LSM are, therefore, obviously superior as a function of stress strength.

Published: October 2023

Purpose

The association between vertical jump and weightlifting performance have been well established often using discrete performance measures such as jump height or peak power which provides little insight into temporal strategies. The purpose of this investigation was to identify currently unassessed temporal countermovement jump metrics and their reliability and relationship to national weightlifting performance.

Methods

A total of 42 national weightlifting athletes (n = 30 females and 12 males), were recruited for this study. Countermovement jump was measured using a force plate following a national and international competition. Vertical ground reaction force and time data were analyzed using a custom script where temporal metrics relating to specific phases of the jump were extracted. Snatch, Clean and Jerk and Total weightlifting performance was obtained following each competition. Reliability of jump metrics were determined using coefficient of variation and interclass correlation coefficient. A Spearman’s Rho, non-parametric bivariate correlation was used to determine the relationship between the jump metrics and weightlifting performance.

Results

From a total of 15 metrics, 13 were deemed reliable, with propulsive impulse showing the greatest level of reliability. Correlational analysis showed strong to very strong (r = 0.676–0.817) relationships between all absolute measures of weightlifting performance and propulsive impulse for both women and men.

Conclusion

This novel finding suggests that practitioners may wish to use propulsive impulse as it may provide more insight into changes of force capabilities following training. Additionally, it may also be used as a talent identification tool given its strong relationship to performance.
Occlusion relationship reasoning with a feature separation and interaction network
Authors: Zhou Yu , Lu Rui , Xue Feng , Gao Yuzhe
Published: October 2023

Occlusion relationship reasoning aims to locate where an object occludes others and estimate the depth order of these objects in three-dimensional (3D) space from a two-dimensional (2D) image. The former sub-task demands both the accurate location and the semantic indication of the objects, while the latter sub-task needs the depth order among the objects. Although several insightful studies have been proposed, a key characteristic of occlusion relationship reasoning, i.e., the specialty and complementarity between occlusion boundary detection and occlusion orientation estimation, is rarely discussed. To verify this claim, in this paper, we integrate these properties into a unified end-to-end trainable network, namely the feature separation and interaction network (FSINet). It contains a shared encoder-decoder structure to learn the complementary property between the two sub-tasks, and two separated paths to learn specialized properties of the two sub-tasks. Concretely, the occlusion boundary path contains an image-level cue extractor to capture rich location information of the boundary, a detail-perceived semantic feature extractor, and a contextual correlation extractor to acquire refined semantic features of objects. In addition, a dual-flow cross detector has been customized to alleviate false-positive and false-negative boundaries. For the occlusion orientation estimation path, a scene context learner has been designed to capture the depth order cue around the boundary. In addition, two stripe convolutions are built to judge the depth order between objects. The shared decoder supplies the feature interaction, which plays a key role in exploiting the complementarity of the two paths. Extensive experimental results on the PIOD and BSDS ownership datasets reveal the superior performance of FSINet over state-of-the-art alternatives. Additionally, abundant ablation studies are offered to demonstrate the effectiveness of our design.
Becoming International
Authors: Bartelson Jens
Published: October 2023

When and how did the modern world become an international one? Jens Bartelson, a leading scholar of the history of international thought, provides new answers to this question by analyzing how relations between polities have been conceptualized across different historical contexts from the sixteenth century to the present day. A global intellectual history of the international system, this book challenges the widespread assumption that this system emerged as a result of a transition from empires to states, instead proposing that the international realm is but a continuation of imperial relations by other means. Showing how the international system spread through the creative appropriation of European concepts of nation and state by non-Europeans, Bartelson argues that this system has taken on a life of its own, to the point of becoming an empire in its own right.
The importance of developing a financial audit process: An academic medical center perspective
Authors: Fritter Jessica , Harper Cody
Published: October 2023

Clinical research studies run the risk of being in a deficit leading to premature study termination or a desperate struggle to find new funding to continue the research. It is important for institutions, small or large, to have financial oversight during the research process. We created a financial audit process for a core clinical research department at a pediatric hospital. Understanding where to find your costs, what costs are important, and other elements of the audit process are essential. Knowing how to replicate a financial audit process can help you eliminate the risk of a financial deficit.

Authors: Cheng Alex C. , Dunkel Leah , Byrne Loretta M. , Tischbein Maeve , Burts Delicia , Hamilton Jahi , Phillips Kaysi , Embry Bryce , Tan Jason , Olson Erik , Harris Paul A.
Published: October 2023

Background:

Obtaining complete and accurate information in recruitment registries is essential for matching potential participants to research studies for which they qualify. Since electronic health record (EHR) systems are required to make patient data available to external systems, an interface between EHRs and recruitment registries may improve accuracy and completeness of volunteers’ profiles. We tested this hypothesis on ResearchMatch (RM), a disease- and institution-neutral recruitment registry with 1357 studies across 255 institutions.

Methods:

We developed an interface where volunteers signing up for RM can authorize transfer of demographic data, medical conditions, and medications from the EHR into a registration form. We obtained feedback from a panel of community members to determine acceptability of the planned integration. We then developed the EHR interface and performed an evaluation study of 100 patients to determine whether RM profiles generated with EHR-assisted adjudication included more conditions and medications than those without the EHR connection.

Results:

Community member feedback revealed that members of the public were willing to authenticate into the EHR from RM with proper messaging about choice and privacy. The evaluation study showed that out of 100 participants, 75 included more conditions and 69 included more medications in RM profiles completed with the EHR connection than those without. Participants also completed the EHR-connected profiles in 16 fewer seconds than non-EHR-connected profiles.

Conclusions:

The EHR to RM integration could lead to more complete profiles, less participant burden, and better study matches for many of the over 148,000 volunteers who participate in ResearchMatch.
Hydrodynamic force on a small squirmer moving with a time-dependent velocity at small Reynolds numbers
Authors: Redaelli T. , Candelier F. , Mehaddi R. , Eloy C. , Mehlig B.
Published: October 2023

We calculate the hydrodynamic force on a small spherical, unsteady squirmer moving with a time-dependent velocity in a fluid at rest, taking into account convective and unsteady fluid inertia effects in perturbation theory. Our results generalise those of Lovalenti & Brady (J. Fluid Mech., vol. 256, 1993, pp. 561–605) from passive to active spherical particles. We find that convective inertia changes the history contribution to the hydrodynamic force, as it does for passive particles. We determine how the hydrodynamic force depends on the swimming gait of the unsteady squirmer. Since swimming breaks the spherical symmetry of the problem, the force is not determined completely by the outer solution of the asymptotic matching problem, as it is for passive spheres. There are additional contributions due to the inhomogeneous solution of the inner problem. We also compute the disturbance flow, illustrating convective and unsteady effects when the particle experiences a sudden start followed by a sudden stop.

Prevalence and risk factors of physical violence against husbands: evidence from India
Authors: Chattopadhyay Aparajita , Kumar Sharma Santosh , Vishwakarma Deepanjali , Jungari Suresh
Published: October 2023

As the proportion of women being victims of spousal violence in India is higher than men, laws are usually framed to safeguard women. However, men who have experienced physical spousal violence are not unheard of. The study aims to provide the nationwide prevalence of physical violence against husbands and the risk factors for such violence, using large-scale nationally representative ‘National Family Health Survey’ (NFHS 4) data. The study used descriptive, bivariate, logistic, and multilevel regression models with a random intercept clustering within states and households to explain the physical violence against husband. Sample size for the analysis was 62,716 currently married women aged 15–49 years. Findings revealed that in most of the states of India, physical spousal violence has increased over time. Behavioural characteristics like marital control, alcoholism, and childhood experience of parental violence have a consistent and strong role in explaining the experience of physical violence across states. With age, experience of violence against husbands increases. Differences in socio-economic characteristics do not have unidirectional effect on violence experienced by husbands across regions of India. Working women who are earning cash and having access to mobile phones perpetrate more physical violence in selected regions. Education shows a gradient on such violence perpetration, indicating that only after achieving a certain level of education, chances of violence reduce. Regionally contrasting social and economic risk factors in explaining violence strengthen the argument that violence is space and culture-specific, and development alone may not resolve violence unless the system is addressing the behavioural aspects. There is a need for supporting men experiencing domestic violence within the existing system facilities. Revisiting the present domestic violence laws and programmes for inclusivity is the need of the hour.
Meritocracy, Suzhi Education and the Use of Live-Streaming Technology in Rural Schools in Western China
Authors: Li Miao , Zhang Qiang
Published: October 2023

Many rural youths in China receive a poor-quality, strict and exam-oriented education. In everyday and professional discourses, incorporating live-streaming technologies in rural schooling is tied to promises of improved educational quality and a narrowed urban‒rural education gap. Reflecting a dystopian ideology of meritocracy, this article investigates how live-streaming technologies transmit suzhi (human quality) education and downplay the exam-oriented education with which rural students and teachers are familiar. The authors argue that the two educational vehicles for meritocracy work together to channel students to a seemingly meritocratic pathway of social mobility but funnel rural students to an inferior educational track according to their rural registration and lower-class backgrounds. The online version of suzhi education complicates and even exacerbates the already fierce educational competition that rural students face. Rural students’ low aspirations and their teachers’ apathy towards live-streaming classes challenge the purportedly transformative effects of live-streaming technologies in China's rural schooling.

Published: October 2023

Introduction:

Cardiac arrhythmias are a major concern in patients with CHD. The purpose of this study was to evaluate the long-term outcomes in patients with CHD submitted to catheter ablation.

Materials and Methods:

Observational retrospective study of patients with CHD referred for catheter ablation from January 2016 to December 2021 in a tertiary referral centre. Acute procedural endpoints and long-term outcomes were assessed.

Results:

A total of 44 ablation procedures were performed in 36 CHD patients (55% male, mean age 43 ±3 years). Fifty-four arrhythmias were ablated: 23 cavotricuspid isthmus atrial flutters, 10 atrial re-entrant tachycardias, eight focal atrial tachycardias, eight atrial fibrillations, three atrioventricular re-entrant tachycardias, and two ventricular tachycardias. During a median follow-up time of 37 months (interquartile range 12–51), freedom from arrhythmia recurrence was achieved in 93%, with 1.2 procedures per patient (18% with anti-arrhythmic drugs). There were no adverse events related to catheter ablation. No predictors of recurrence were identified.

Conclusion:

In patients with CHD, catheter ablation presents a high mid-term efficacy while maintaining a safe profile.
Key Factors Determining the Formation of Sulfate Aerosols Through Multiphase Chemistry—A Kinetic Modeling Study Based on Beijing Conditions

Published: October 2023

Severe haze in Beijing is characterized by the rapid formation of sulfate via the multiphase oxidation of SO2. While many factors, including aerosol oxidants and atmospheric variables, were discovered and investigated, their relative importance remains unclear. Herein, based on the field observation data obtained in Beijing, China, we developed a kinetic model to explore the key factors that determine the multiphase formation of sulfate. Sensitivity tests give the kinetics of each oxidation pathway varying with pH and temperature, based on which the total sulfate formation rate at room temperature (298 K) is calculated to be generally greater than that at standard temperature (273 K), especially during nighttime. Interfacial oxidants are responsible for sulfate formation within a wide pH range, and transition metal ions become more efficient with increased temperature. The multiphase chemistry is additionally affected by aerosol liquid water content (ALWC), particle radius (Rp), and ionic strength (IS). Within the usual aerosol acidity, the kinetic discrepancy induced by different ALWC levels is more significant at the lower temperature, in contrast to the temperature dependence related to Rp, and the effect of IS depends highly on pH. Machine learning reveals the potential importance of temperature, acidity, and Rp. Temperature and acidity are impactful for the formation of both aqueous and interfacial sulfates, whereas Rp only affects the interfacial processes. The discrepancy between nighttime and daytime is considered throughout this study. Overall, this study reveals the key factors for multiphase sulfate formation and is recommended for kinetic evaluation in future laboratory research.
Crystallization of Superfast‐Spreading Oceanic Crust (ODP Hole 1256D, Pacific Ocean): Constraints From Zircon Geochronology
Authors: Lissenberg C. Johan , Condon Daniel J. , Smye Andrew J. , Anma Ryo
Published: October 2023

Studies of oceanic crust, which covers a large proportion of the Earth's surface, have provided significant insight into the dynamics of crustal accretion processes at mid‐ocean ridges. It is now recognized that the nature of oceanic crust varies fundamentally as a function of spreading rate. Ocean Drilling Program (ODP) Hole 1256D (eastern Pacific Ocean) was drilled into the crust formed at a superfast spreading rate, and hence represents a crustal end member. Drilling recovered a section through lava and sheeted dykes and into the plutonic sequence, the study of which has yielded abundant insight into magmatic and hydrothermal processes operating at high spreading rates. Here, we present zircon U‐Pb dates for Hole 1256D, which constrain the age of the section, as well as the duration of crustal accretion. We find that the main pulse of zircon crystallization within plutonic rocks occurred at 15.19 Ma, consistent with magnetic anomalies, and lasted tens of thousands of years. During this episode, the main plutonic body intruded, and partial melts of the base of the sheeted dykes crystallized. One sample appears to postdate this episode by up to 0.25 Myr, and may be an off‐axis intrusion. Overall, the duration of crustal accretion was tens to several hundreds of thousands of years, similar to that found at the fast‐spreading East Pacific Rise and the slow‐spreading Mid‐Atlantic Ridge. This indicates that crustal accretion along slow‐ to superfast‐spreading ridges occurs over similar time scales, with substantially longer periods of accretion occurring at ultraslow‐spreading ridges characterized by thick lithosphere.
Studying Brown Ocean Re‐Intensification of Hurricane Florence Using CYGNSS and SMAP Soil Moisture Data and a Numerical Weather Model
Authors: Li Zhi , Tiwari Alka , Sui Xinxin , Garrison James , Marks Frank , Niyogi Dev
Published: October 2023

Hurricane Florence made landfall over the Carolinas 14 September 2018, bringing over 30 inches of rainfall. What remains understudied is the possible storm re‐intensification by wet and warm antecedent soil moisture (ASM), known as the Brown Ocean Effect (BOE). This study investigates this effect with two approaches: (a) two satellite‐based soil moisture (SM) data and (b) model simulation. The averaged Cyclone Global Navigation System and Soil Moisture Active Passive SM enables examination of land‐atmosphere interaction at a sub‐daily scale. Both observations and simulation results manifest positive feedback between ASM and rainfall intensity, with 3 days prior to landfall being the typical antecedent time scale. Wet (dry) ASM lead to intense (light) and concentrated (widespread) rains. We also found that soil temperature can modulate the BOE. This study aims to advance our understanding of land‐atmosphere feedback and calls to acquire accurate antecedent land states to enhance forecast skills.
Potential Predictability of the Spring Bloom in the Southern Ocean Sea Ice Zone

Published: October 2023

Every austral spring when Antarctic sea ice melts, favorable growing conditions lead to an intense phytoplankton bloom, which supports much of the local marine ecosystem. Recent studies have found that Antarctic sea ice is predictable several years in advance, suggesting that the spring bloom might exhibit similar predictability. Using a suite of perfect model predictability experiments, we find that November net primary production (NPP) is potentially predictable 7 to 10 years in advance in many Southern Ocean regions. Sea ice extent predictability peaks in late winter, followed by absorbed shortwave radiation and NPP with a 2 to 3 months lag. This seasonal progression of predictability supports our hypothesis that sea ice and light limitation control the inherent predictability of the spring bloom. Our results suggest skillful interannual predictions of NPP may be achievable, with implications for managing fisheries and the marine ecosystem, and guiding conservation policy in the Southern Ocean.

Intense eruptions of the Tonga volcano activated prominent traveling atmospheric disturbances (TADs) at 04:05UT on 15 January 2022. Himawari‐8 satellite images depict that TADs of the tropospheric Lamb wavefront propagate with a speed of 315 m/s and arrive in Taiwan at 11:30UT. Networks of 98 barometers, 28 tide gauges, an ionosonde, and 10 magnetometers are used to study the responses of magnetic fields to TADs in Taiwan. The horizontal components in magnetic field changes of the Taiwan magnetometers all point toward and away from the Tonga volcano at 11:00–12:00UT upon the tropospheric Lamb wavefront arrival and at 22:00–23:00UT when the thermospheric Lamb wavefront with speeds of 487 m/s coming, respectively. Analyses of the raytracing and beamforming techniques on the horizontal components in magnetic field changes of 69 INTERMAGNET magnetometers show that both tropospheric and thermospheric Lamb waves efficiently activate traveling ionospheric disturbances and modify ionospheric currents of the globe.

In 2022, the Hunga volcano eruption in Tonga generated atmospheric pressure waves that propagated globally and produced tsunamis in all the world's oceans. The largest pressure wave, with an amplitude of several hundred pascals, is the Lamb wave. Standard Lamb wave models, incorporating the sound‐speed as a function of temperature, satisfactorily explain observations in the near‐field but not in the far‐field. We show that an augmented Lamb wave model that includes the effects of wind and topography accurately reproduces the wavefronts observed by satellites and barometers, including those close to the antipode. Winds, first suggested to explain the travel times of Lamb waves from Krakatau in 1883, are now shown to also play a major role in shaping their waveforms; temperature and topography play smaller, but still detectable, roles. Our augmented model provides a significant advance for the development of early warning and hazard assessments for the meteotsunamis these waves produce.

Mathematical models in engineering play an important role in understanding and predicting the behavior of a system. A mechanistic coupled liquid water, water vapor and heat transfer model incorporating kinetic phase change accounting for real‐time interfacial area between water and gas phases was developed to predict coupled subsurface processes and evaporation (drying) rates from bare soils. To enhance the model capability to predict evaporation rates, the air resistance associated with the viscous sublayer was implemented in energy and mass exchange across the soil‐air interface (the land‐atmosphere boundary condition [BC]). The atmospheric stability condition was also considered in the calculation of sensible heat and vapor fluxes at the ground surface. This comprehensive model was validated against measured field data from bare soil test plots from a green roof study, during temperate summer conditions in Canada, demonstrating that the model captured the main coupled processes in the subsurface of bare soil during drying periods. A sensitivity analysis was performed to determine the importance of various components of the comprehensive model. Removal of viscous sublayer resistance in the vapor transfer BC resulted in poorer predictions of evaporation (drying) rates. Incorporating the atmospheric stability function accounting for real‐time atmospheric conditions did not improve the predictive capability for the simulated drying events compared to the case when only a neutral atmospheric condition was implemented. Neglecting heat transfer associated with hydrodynamic dispersion of water vapor in the subsurface had limited impact on subsurface temperature predictions.

Alcohol use disorder (AUD) affects transcriptomic, epigenetic and proteomic expression in several organs, including the brain. There has not been a comprehensive analysis of altered protein abundance focusing on the multiple brain regions that undergo neuroadaptations occurring in AUD. We performed a quantitative proteomic analysis using a liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis of human postmortem tissue from brain regions that play key roles in the development and maintenance of AUD, the amygdala (AMG), hippocampus (HIPP), hypothalamus (HYP), nucleus accumbens (NAc), prefrontal cortex (PFC) and ventral tegmental area (VTA). Brain tissues were from adult males with AUD (n = 11) and matched controls (n = 16). Across the two groups, there were >6000 proteins quantified with differential protein abundance in AUD compared to controls in each of the six brain regions. The region with the greatest number of differentially expressed proteins was the AMG, followed by the HYP. Pathways associated with differentially expressed proteins between groups (fold change > 1.5 and LIMMA p < 0.01) were analyzed by Ingenuity Pathway Analysis (IPA). In the AMG, adrenergic, opioid, oxytocin, GABA receptor and cytokine pathways were among the most enriched. In the HYP, dopaminergic signaling pathways were the most enriched. Proteins with differential abundance in AUD highlight potential therapeutic targets such as oxytocin, CSNK1D (PF-670462), GABAB receptor and opioid receptors and may lead to the identification of other potential targets. These results improve our understanding of the molecular alterations of AUD across brain regions that are associated with the development and maintenance of AUD.

Fear learning is essential to survival, but traumatic events may lead to abnormal fear consolidation and overgeneralization, triggering fear responses in safe environments, as occurs in post-traumatic stress disorder (PTSD). Adenosine A2A receptors (A2AR) control emotional memory and fear conditioning, but it is not known if they affect the consolidation and generalization of fear, which was now investigated. We now report that A2AR blockade through systemic administration of the A2AR antagonist SCH58261 immediately after contextual fear conditioning (within the consolidation window), accelerated fear generalization. Conversely, A2AR activation with CGS21680 decreased fear generalization. Ex vivo electrophysiological recordings of field excitatory post-synaptic potentials (fEPSPs) in CA3-CA1 synapses and of population spikes in the lateral amygdala (LA), showed that the effect of SCH58261 is associated with a reversion of fear conditioning-induced decrease of long-term potentiation (LTP) in the dorsal hippocampus (DH) and with increased amplitude of LA LTP in conditioned animals. These data suggest that A2AR are engaged during contextual fear consolidation, controlling long-term potentiation mechanisms in both DH and LA during fear consolidation, impacting on fear generalization; this supports targeting A2AR during fear consolidation to control aberrant fear processing in PTSD and other fear-related disorders.
Practical advice for successful clinical treatment with resin-bonded bridges

Resin-bonded bridges are one of the main options for replacing missing teeth for hypodontia patients. This technique offers several advantages for these patients, who are often young, have unrestored abutment teeth, and have had tooth positions optimised by orthodontic treatment. However, the replacement of missing teeth can be challenging due to tooth positions and anomalies of abutment tooth shape and size.

These patients are often young adults at the time of restoration, making the minimally invasive nature and predictable long-term success of resin-bonded bridges advantageous over other treatment methods.

This paper in the hypodontia themed issue discusses the importance of case selection and gives practical advice for the design and provision of resin-bonded bridges.

Hematopoietic stem cell (HSC) gene therapy has curative potential; however, its use is limited by the morbidity and mortality associated with current chemotherapy-based conditioning. Targeted conditioning using antibody-drug conjugates (ADC) holds promise for reduced toxicity in HSC gene therapy. Here we test the ability of an antibody-drug conjugate targeting CD117 (CD117-ADC) to enable engraftment in a non-human primate lentiviral gene therapy model of hemoglobinopathies. Following single-dose CD117-ADC, a >99% depletion of bone marrow CD34 + CD90 + CD45RA- cells without lymphocyte reduction is observed, which results are not inferior to multi-day myeloablative busulfan conditioning. CD117-ADC, similarly to busulfan, allows efficient engraftment, gene marking, and vector-derived fetal hemoglobin induction. Importantly, ADC treatment is associated with minimal toxicity, and CD117-ADC-conditioned animals maintain fertility. In contrast, busulfan treatment commonly causes severe toxicities and infertility in humans. Thus, the myeloablative capacity of single-dose CD117-ADC is sufficient for efficient engraftment of gene-modified HSCs while preserving fertility and reducing adverse effects related to toxicity in non-human primates. This targeted conditioning approach thus provides the proof-of-principle to improve risk-benefit ratio in a variety of HSC-based gene therapy products in humans.
