Abstract3D printing is a promising technology for recycling agricultural waste by liquid deposition modeling (LDM). In this paper, we propose a novel method for recycling agricultural waste to be used in liquid deposition 3D printing. The method involves converting agricultural waste into suitable powder by grinding and sieving procedures. Then, a paste is prepared based on the powder from agricultural waste, which is then subjected to mechanical and physical testing to study its properties. A 3D printing setup is used to print samples for applying mechanical testing to study the properties of 3D-printed agricultural waste. The results of the mechanical and physical testing showed that the agricultural waste paste has promising properties for 3D printing. The paste is strong and durable, and it can be used to print a variety of different products. The results of this research paper demonstrate the potential of 3D printing to recycle agricultural waste and create new products.
Brain chains as topological signatures for Alzheimer’s disease

Published: April 2024

AbstractTopology is providing new insights for neuroscience. For instance, graphs, simplicial complexes, directed graphs, flag complexes, persistent homology and convex covers have been used to study functional brain networks, synaptic connectivity, and hippocampal place cell codes. We propose a topological framework to study the evolution of Alzheimer’s disease, the most common neurodegenerative disease. The modeling of this disease starts with the representation of the brain connectivity as a graph and the seeding of a toxic protein in a specific region represented by a vertex. Over time, the accumulation of toxic proteins at vertices and their propagation along edges are modeled by a dynamical system on this graph. These dynamics provide an order on the edges of the graph according to the damage created by high concentrations of proteins. This sequence of edges defines a filtration of the graph. We consider different filtrations given by different disease seeding locations. To study these filtrations we propose a new combinatorial and topological method. A filtration defines a maximal chain in the partially ordered set of spanning subgraphs ordered by inclusion. To identify similar graphs, and define a topological signature, we quotient this poset by graph homotopy equivalence, which gives maximal chains in a smaller poset. We provide an algorithm to compute this direct quotient without computing all subgraphs and then propose bounds on the total number of graphs up to homotopy equivalence. To compare the maximal chains generated by this method, we extend Kendall’s $$d_K$$

d
K

metric for permutations to more general graded posets and establish bounds for this metric. We then demonstrate the utility of this framework on actual brain graphs by studying the dynamics of tau proteins on the structural connectome. We show that the proposed topological brain chain equivalence classes distinguish different simulated subtypes of Alzheimer’s disease.
Using Preliminary Data to Guide a Research Project: Bear Safety and Bear Management
Authors: Harmon Justin 
Published: April 2024

AbstractThis methodological and theoretical note is the cornerstone of empirical research I began this past summer (2023) on bear safety in backcountry wilderness settings. I am using this pilot data to inform the future iterations of the study to learn more about people’s relationships to bears and their knowledge of safe practices while recreating in the presence of bears. This note, written in the early months of 2024, focuses on refining the pilot survey and developing the research program which will be expanded to four locations in the U.S. to assess the knowledge of backcountry hikers regarding bear safety and their preferences for bear management. This essay ponders the development of future iterations of this research agenda, including methodology, theoretical development, and practical value.

Authors: Oud Frederike M. M. , Meulman Meggie D. , Merten Hanneke , Wagner Cordula , van Munster Barbara C. 
Published: April 2024

Abstract
Background
Dutch hospitals are required to screen older patients for the risk of developing functional decline using the Safety Management System (VMS) which assesses four domains associated with functional decline; fall risk, risk of delirium, malnutrition, and physical impairment.

Purpose
The aim is twofold, first to compare the VMS frailty instrument as a frailty screener with existing frailty instruments and second to provide an overview of the available evidence.

Methods
We performed a literature search to identify studies that used the VMS instrument as frailty screener to asses frailty or to predict adverse health outcomes in older hospitalized patients. Pubmed, Cinahl, and Embase were searched from January 1st 2008 to December 11th 2023.

Results
Our search yielded 603 articles, of which 17 studies with heterogenous populations and settings were included. Using the VMS, frailty was scored in six different ways. The agreement between VMS and other frailty instruments ranged from 57 to 87%. The highest sensitivity and specificity of VMS for frailty were 90% and 67%, respectively. The association of the VMS with outcomes was studied in 14 studies, VMS was predictive for complications, delirium, falls, length of stay, and adverse events. Conflicting results were found for hospital (re)admission, complications, change in living situation, functional decline, and mortality.

Conclusion
The VMS frailty instrument were studied as a frailty screening instrument in various populations and settings. The value of the VMS instrument as a frailty screener looks promising. Our results suggest that the scoring method of the VMS could be adapted to specific requirements of settings or populations.

Published: April 2024

AbstractUnveiling the intersection of technology and art, this research aims to explore the vital role of Computational Intelligence (CI) techniques in shaping digital theater performances within virtual worlds by managing student populations engaged in these productions. The realm of digital theater offers opportunities for creative expression and collaboration. This necessitates the integration of Computational Intelligence (CI) to establish cohesive teams in digital theater. By doing so, effective collaboration is promoted, and creativity is dynamically enhanced in virtual cultural environments and digital worlds. Central to this study is the use of a CI algorithm called Flying Fox Optimizer, designed to form homogeneous student groups, and optimize theater dynamics. The algorithm utilizes fuzzy logic, eliminating the requirement for fine-tuning by the user. The results reveal that through this mechanism, theater educators of the future can effortlessly create student groups that foster seamless collaboration in virtual theater education.
Deep Hawkes process for high-frequency market making
Authors: Kumar Pankaj 
Published: April 2024

AbstractHigh-frequency market making is a liquidity-providing trading strategy that simultaneously generates many bids and asks for a security at ultra-low latency while maintaining a relatively neutral position. The strategy makes a profit from the bid-ask spread for every buy and sell transaction, against the risk of adverse selection, uncertain execution and inventory risk. We design realistic simulations of limit order markets and develop a high-frequency market making strategy in which agents process order book information to post the optimal price, order type and execution time. By introducing the Deep Hawkes process to the high-frequency market making strategy, we allow a feedback loop to be created between order arrival and the state of the limit order book, together with self- and cross-excitation effects. Our high-frequency market making strategy accounts for the cancellation of orders that influence order queue position, profitability, bid-ask spread and the value of the order. The experimental results show that our trading agent outperforms the baseline strategy, which uses a probability density estimate of the fundamental price. We investigate the effect of cancellations on market quality and the agent’s profitability. We validate how closely the simulation framework approximates reality by reproducing stylised facts from the empirical analysis of the simulated order book data.
Role of the β2-adrenergic receptor in podocyte injury and recovery

Published: April 2024

Abstract
Background
Podocytes have a remarkable ability to recover from injury; however, little is known about the recovery mechanisms involved in this process. We recently showed that formoterol, a long-acting β2-adrenergic receptor (β2-AR) agonist, induced mitochondrial biogenesis (MB) in podocytes and led to renoprotection in mice. However, it is not clear whether this effect was mediated by formoterol acting through the β2-AR or if it occurred through “off-target” effects.

Methods
We genetically deleted the β2-AR specifically in murine podocytes and used these mice to determine whether formoterol acting through the podocyte β2-AR alone is sufficient for recovery of renal filtration function following injury. The podocyte-specific β2-AR knockout mice (β2-ARfl/fl/PodCre) were generated by crossing β2-AR floxed mice with podocin Cre (B6.Cg-Tg(NPHS2-cre)295Lbh/J) mice. These mice were then subjected to both acute and chronic glomerular injury using nephrotoxic serum (NTS) and adriamycin (ADR), respectively. The extent of injury was evaluated by measuring albuminuria and histological and immunostaining analysis of the murine kidney sections.

Results
A similar level of injury was observed in β2-AR knockout and control mice; however, the β2-ARfl/fl/PodCre mice failed to recover in response to formoterol. Functional evaluation of the β2-ARfl/fl/PodCre mice following injury plus formoterol showed similar albuminuria and glomerular injury to control mice that were not treated with formoterol.

Conclusions
These results indicate that the podocyte β2-AR is a critical component of the recovery mechanism and may serve as a novel therapeutic target for treating podocytopathies.

Published: April 2024

AbstractExperiential learning in biomedical engineering curricula is a critical component to developing graduates who are equipped to contribute to technical design tasks in their careers. This paper presents the development and implementation of an undergraduate and graduate-level soft material robotics design course focused on applications in medical device design. The elective course, offered in a bioengineering department, includes modules on technical topics and hands-on projects relevant to readings, all situated within a human-centered design course. After learning and using first principles governing soft robot design and exploring literature in soft robotics, students propose a new advance in the field in a hands-on design and prototype project. The course described here aims to create a structure to engage students in fabrication and the design approaches taken by practitioners in a specific field, applied here in soft robotics, but applicable to other areas of biomedical engineering. This teaching tips article details the pedagogical tools used to facilitate design and collaboration within the course. Additionally, we aim to highlight ways in which the course creates (1) opportunities to engage undergraduates in design in preparation for capstone courses, (2) outward facing opportunities to connect with practitioners in the field, and (3) the ability to adapt this hands-on experience within a typical lecture structure as well as a hybrid online and in-person offering, thus expanding its utility in bioengineering departments. We reflect on course elements that can inform future design-based course offerings in soft robotics and other design-based multidisciplinary fields in bioengineering.
Foredune erosion, overtopping and destruction in 2022 at Bengello Beach, southeastern Australia

Published: April 2024

AbstractThe beach–foredune system at Bengello Beach has been monitored monthly to bimonthly at four profiles (P1–P4) since 1972 and documented the building of a foredune. This paper addresses the remarkable changes which occurred in 2022 as storm waves overtopped and trimmed this foredune at all profiles, then later removed this entire feature at two of the profiles (P3, P4) but not the others (P1, P2). Wave parameters for these storm events, measured by deepwater and nearshore wave buoys, enable a comparison of storm characteristics and resulting beach–foredune impact. During the storm event which destroyed the foredune, nearshore wave height exceeded deepwater wave height, in contrast with other storms that year. The beach–foredune lost 78 m3/m in 2022 and the notable 1974 storms that impacted this coastline resulted in 95 m3/m volume loss. During 2023, beach recovery has occurred, but not rebuilt the foredune. It had persisted for ~40 years enduring many other severe storm events, and the coastal protection afforded by the dune system has been compromised. This highlights the need to consider dune morphology in assessments of erosion hazard and inundation risk along similar coastlines.
Poissonian pair correlation for directions in multi-dimensional affine lattices and escape of mass estimates for embedded horospheres
Authors: KIM WOOYEON , MARKLOF JENS 
Published: April 2024

AbstractWe prove the convergence of moments of the number of directions of affine lattice vectors that fall into a small disc, under natural Diophantine conditions on the shift. Furthermore, we show that the pair correlation function is Poissonian for any irrational shift in dimension 3 and higher, including well-approximable vectors. Convergence in distribution was already proved in the work of Strömbergsson and the second author [The distribution of free path lengths in the periodic Lorentz gas and related lattice point problems. Ann. of Math. (2)172 (2010), 1949–2033], and the principal step in the extension to convergence of moments is an escape of mass estimate for averages over embedded

Published: April 2024

Abstract
Mental health conditions, recognised as a global crisis, were further exacerbated by the COVID-19 pandemic. Access to mental health services remains limited, particularly in low-income regions. Task-sharing interventions, exemplified by Problem Management Plus (PM+), have emerged as potential solutions to bridge this treatment gap. This study presents an evaluation of the PM+ scale-up in Sub-Saharan Africa (Ethiopia and Benin) and Eastern Europe (Croatia and Bosnia and Herzegovina) as part of a mental health and psychosocial support programming including 87 adult participants. A mixed-method approach assesses the impact of the intervention. Quantitative analyses reveal significant reductions in self-reported problems, depression, anxiety and improved functioning. Qualitative data highlight four main themes: general health, family relationships, psychosocial problems and daily activities. These thematic areas demonstrate consistent improvements across clients, irrespective of the region. The findings underscore the impact of PM+ in addressing a broad spectrum of client issues, demonstrating its potential as a valuable tool for mitigating mental health challenges in diverse settings. This study contributes to the burgeoning body of evidence supporting PM+ and highlights its promise in enhancing mental health outcomes on a global scale, particularly for vulnerable populations.
The Goldbugs Go Global: The Philippines, China, and the Foundations of Development
Authors: Fulfer Johnny D. 
Published: April 2024

AbstractWhile historians have recently called attention to the racial assumptions that shaped the debates over monetary reform in either the colonial Philippines or China during the first years of the twentieth century, this article analyzes the crosscurrents between efforts to “civilize” and “develop” Filipino and Chinese monetary systems. It first examines the history of the Philippine money question (1899–1903), revealing anxieties about the apparent attachment Native Filipinos and Chinese had to silver currency. U.S. colonial officials were ambivalent toward the Native Filipinos, seeing them as possibly teachable, but so-called silver savagism was seen as too deeply engrained in the Chinese community, making the Chinese appear as a threat to monetary stability. In the last section, the article turns to China, revealing how the outcome of the Philippine money question shaped how U.S. monetary experts approached their efforts to reform China’s monetary system. Throughout this process, U.S. colonial officials and monetary experts defined the Philippines and China (“silver countries”) and Filipinos and Chinese (“silver-handling types”) as overlapping objects of development. This analysis reveals how development was simultaneously an economic, racial, and imperial language.
Investigating Potential Ecological Benefits From Mariculture

Published: April 2024

AbstractMariculture has been gradually regarded as an important solution to the global food production crisis. Increasing scientific evidence reveals that mariculture can provide a large number of ecologic benefits, in accordance with several United Nations sustainable development goals. However, previous studies mostly focused on the negative impacts of mariculture, which may impede its increased production. Here, based on Emergy Accounting (EMA), we propose a comprehensive “Multiple Inputs‐Ecosystem Service Multifunctionality‐Multiple Environmental Impacts” (MI‐ESM‐MEI) evaluation framework, trying to describe mariculture's overall environmental performances beyond just limiting to the production of seafoods. As the world's largest mariculture producer, China is taken as an example for evaluation. Our results show that both cultured species and cultivation patterns determine the environmental performance of mariculture: seaweed‐raft, shellfish‐raft, shellfish‐hanging cage, shellfish‐bottom sowing and others‐bottom sowing mariculture could be more influential in environmental support. By identifying priority areas for offshore mariculture development, ecological benefits can be significantly improved using about 27% of China's territorial sea area. At present, mariculture in Liaoning, Shandong, Jiangsu, and Zhejiang performs better than that in other regions. Under the condition of recognizing nonnegligible ecological benefits of mariculture, additional improvements for more sustainable development are urgently needed. In addition, mariculture activities especially seaweed mariculture can help solve water contamination problem and alleviate the effects of eutrophication on coastal ecosystems. For most China coastal regions, if integrated multi‐trophic aquaculture (IMTA) mode can be promoted, the ecological burden of mariculture can be reduced and even converted into ecological benefit.

AbstractThe micro Advanced Stellar Compass is an attitude reference for the MAG investigation onboard Juno. The μASC camera head unit images the star field with a CCD that is also sensitive to particles with enough energy to pass through the camera shielding: >15 MeV electrons and >80 MeV protons. This provides the capability to monitor fluxes of high‐energy particles in Jupiter’s magnetosphere. A survey of energetic electron fluxes sampled during the first 47 Juno orbits reveals instances of variations observed when Juno is traversing the M‐shell of the Galilean moons. Juno's traversal of the Europa M‐shell often results in distinctly particle signatures. We present the μASC observations of increased electron flux during the crossing of Europa’s plasma wake, and depletion of energetic electron flux on the upstream side. The upstream/downstream differences indicate that the wake environment of Europa drives strong pitch angle scattering on relativistic electrons.
Fast Seismic Anomalies Under Continents Explained by the Delaminated Lower Continental Crust—Implications From High Pressure‐Temperature Elasticity of Jadeite
Authors: Hao Ming , Zhou Wen‐Yi , Dera Przemyslaw , Schmandt Brandon , Zhang Dongzhou , Zhang Jin S. 
Published: April 2024

AbstractSeismic tomography has shown that the shear wave velocities (Vs) under continents, especially under cratons, are extremely fast at 100–200 km depth, which is difficult to explain by low temperatures or high Mg#. Alternatively, delaminated eclogitic lower continental crust has been proposed to account for these fast seismic anomalies. However, the thermoelastic properties of jadeite which constitutes up to 60–80 mol% of clinopyroxene in the potentially delaminated lower continental crust are not well constrained. In this study, we measured the single‐crystal elasticity of jadeite by Brillouin spectroscopy under simultaneous high pressure and temperature conditions for the first time. We found that the temperature dependence of Vs of jadeite is extremely small if not negligible. The seismic velocities of the potentially delaminated lower continental crusts were subsequently modeled and found to match the widely observed fast seismic anomalies under cratons between 100 and 200 km depth.
Larger Dust Cooling Effect Estimated From Regionally Dependent Refractive Indices

Published: April 2024

AbstractThe dust direct radiative effect (DRE) depends strongly on the dust particle size distribution (PSD) and complex refractive index (CRI). Although recent studies constrained the dust PSD in the models, its CRI uncertainties are still large. As a result, whether dust warms or cools the climate system remains unclear. Here, we estimate the dust DRE by employing the regionally‐dependent dust CRI based on global measurements. We find that new dust CRI significantly enhances the scattering of dust in the shortwave while reduces its absorption in the longwave, which is opposite to that caused by increasing the coarse and giant dust fraction via constraining the PSD. Constraining both PSD and CRI ultimately leads to a net dust DRE of −0.68 W m−2, a cooling stronger than current model estimates.
