A Multiperiod, Multicommodity, Capacitated International Agricultural Trade Network Equilibrium Model with Applications to Ukraine in Wartime
Authors: Hassani Dana , Nagurney Anna , Nivievskyi Oleg , Martyshev Pavlo
Published: August 2024

The world is facing immense challenges because of increasing strife and the impacts of climate change with accompanying disasters, both sudden-onset as well as slow-onset ones, which have affected the trade of agricultural commodities needed for food security. In this paper, a multiperiod, multicommodity, international, agricultural trade network equilibrium model is constructed with capacity constraints on the production, transportation, and storage of agricultural commodities. The model allows for multiple routes between supply and demand country markets, different modes of transport, and storage in the producing and consuming countries as well as in the intermediate countries. The generality of the underlying functions, coupled with the capacity constraints, allow for the modeling of competition among agricultural commodities for production, transportation, and storage. The capacity constraints also enable the quantification of various disaster-related disruptions to production, transportation, and storage on the volumes of commodity flows as well as on the prices. A series of numerical examples inspired by the effects of Russia’s full-scale invasion of Ukraine on agricultural trade is presented, and the results are analyzed to provide insights into food insecurity issues caused by the war.

A Cult by Any Other Name: Is "High Demand Group" a Useful Category? (Perspectives Essay)
Authors: Laycock Joseph P.
Published: August 2024

ABSTRACT: This essay evaluates the use of the term "high demand group" as a substitute for the term "cult." While "high demand group" seems more precise than the word "cult," a review of the literature suggests the two terms are synonymous. The term originated in the 1972 book Why Conservative Churches Are Growing: A Study in the Sociology of Religion , by Dean M. Kelley. Kelley used the phrase "high demand movements" as an ideal type for explaining sociological phenomena. By 1979, the term was being used by the anticult movement as a more persuasive substitute for the word "cult." With this shift, the term "high demand groups" was used to describe a putatively objective phenomenon rather than as a way of organizing the data. Because the term "high demand" emerged out of sociological and economic studies, it carries an air of authority and expertise. By using this term, it is possible to conceal the prejudice engendered in the word "cult" while simultaneously making an appeal to expertise.
Compressed hyperspectral imaging based on image reflection intensity and differential fusion filtering
Authors: Qu Xiaorui , Zhao Jufeng , Tian Haijun , Zhu Junjie , Cui Guangmang
Published: August 2024

Existing spectral imaging technology based on compressed coding requires tens of minutes or even hours to obtain higher-quality spectral data. This limits their use in real dynamic scenarios and can only be discussed theoretically. Therefore, we propose a non-iterative algorithm model based on image reflection intensity-estimation aid (IRI-EA). The algorithm studies the approximate proportional relationship between the reflection strength of the RGB diagram and the corresponding spectrum image and reconstructs high-quality spectral data within about 20 s. By solving the difference map of the corresponding spectral scene, combining it with the spectral data of the IRI method, and introducing the total guidance (TG) filter, the reconstruction error can be significantly reduced, and the spectral reconstruction quality can be improved. Compared with other advanced methods, numerous experimental results indicate the advantages of this method in reconstruction quality and efficiency. Specifically, compared with the existing advanced methods, the average efficiency of our method has improved by at least 85%. Our reconstruction model opens up the possibility of processing real-time video and accelerating other methods.
Experimental demonstration of a Grover-Michelson interferometer

Published: August 2024

We present a low-resource and robust optical implementation of the four-dimensional Grover coin, a four-port linear-optical scatterer that augments the low dimensionality of a regular beam-splitter. While prior realizations of the Grover coin required a potentially unstable ring cavity to be formed, this version of the scatterer does not exhibit any internal interference. When this Grover coin is placed in another system, it can be used for interferometry with a higher-dimensional set of optical field modes. In this case, we formed a Grover-Michelson interferometer, which results when the traditional beam-splitter of a Michelson interferometer is replaced with a four-port Grover coin. This replacement has been shown to remove a phase parameter redundancy in the original Michelson system, now allowing continuous tuning of the shape and slope of the interference pattern. We observed an intensity interferogram with 97% visibility and a phase sensitivity more than an order of magnitude larger than a regular Michelson interferometer. Because this device is readily formed with nearly the same number of optomechanical resources as a Michelson interferometer but can outperform it drastically in phase delay evaluation, it has a great potential to improve many interferometric sensing and control systems.

We propose a silicon photonics fiber coupler consisting of a metastructure containing a through-hole array and a partially etched grating to obtain high efficiency. Using an evolution optimization algorithm, we optimized 121 structural parameters and achieved a minimum feature size of 150 nm, which greatly simplifies the fabrication using wafer-scale foundry services. We designed two structures, one achieving an 86% coupling efficiency into a single fiber, and the other exhibiting a full flat spectrum in the C band. The high-efficiency structure was fabricated using a 300-mm wafer process, and an efficiency of 78% was experimentally evaluated.
LiPro: displaying concurrent image viewing and imperceptible positioning using visible light
Authors: Song Song , Liu Xiangyu , Zhang Xinghao , Zhao Lun , Wu Tingwei , Guo Lei
Published: August 2024

Visible light can be used to achieve effective human interaction with projectors. However, current visible light-based projectors for the target positioning either lose the image viewing function or cause abnormal luminance changes perceived by human eyes, which is not practical for real-world applications. Therefore, we propose a smart lighting-based projector system, LiPro, which can display imperceptible target positioning and any image viewing, simultaneously. In a nutshell, we propose what we believe to be a novel color space conversion modulation scheme to transmit the landmark information, which adds δ and −3δ color intensity value on the red (R) channel and blue (B) channel according to the YCbCr color space analysis, so that human eyes are imperceptible to light intensity changes. Then, we propose the dual-channel decision demodulation scheme, which demodulates the received light signals on both the R channel and B channel at the same time to decide and increase the correctness of the landmark recognition. In the end, we use off-the-shelf devices to implement LiPro to evaluate its performance, and results from extensive experiments show that our LiPro can achieve centimeter-level target positioning under any image viewing conditions.

Crosstalk-avoided 3D full-color holographic displays enabled by single-cell metasurfaces
Authors: Yuan Huan , Tang Wenhao , Zhong Zheqiang , Zhang Bin
Published: August 2024

The metasurface possesses great potential in a 3D holographic display due to its powerful ability to manipulate optical fields, ultracompact structure, and extraordinary information capacity. However, the in-plane and interplane crosstalk caused by the coupling between the meta-atoms of the current 3D holographic metasurface limits the quality of the reconstructed image, which has become a significant obstacle to high-performance 3D display applications. Additionally, the interleaved or multilayer design strategy of metasurfaces increases the complexity of structural design and manufacturing, facing challenges in meeting the requirements for miniaturization and low cost-effectiveness. Here, we propose a strategy for a free-space 3D multiplane color holographic multiplex display based on a single-cell metasurface. By utilizing a modified holographic optimization strategy, multiple holographic information is encoded into three mutually independent bases of incident photons and integrated into a metasurface, thereby creating high-quality 3D vectorial metaholography with minimal crosstalk across the visible spectrum. The proposed metasurface has great potential for applications in augmented reality/virtual reality devices, polarization imaging, holographic data encryption, and information storage.

Recent studies show that cellular neighborhoods play an important role in evolving biological events such as cancer and diabetes. Therefore, it is critical to accurately and efficiently identify cellular neighborhoods from spatially-resolved single-cell transcriptomic data or single-cell resolution tissue imaging data. In this work, we develop CNTools, a computational toolbox for end-to-end cellular neighborhood analysis on annotated cell images, comprising both the identification and analysis steps. It includes state-of-the-art cellular neighborhood identification methods and post-identification smoothing techniques, with our newly proposed Cellular Neighbor Embedding (CNE) method and Naive Smoothing technique, as well as several established downstream analysis approaches. We applied CNTools on three real-world CODEX datasets and evaluated identification methods with smoothing techniques quantitatively and qualitatively. It shows that CNE with Naive Smoothing overall outperformed other methods and revealed more convincing biological insights. We also provided suggestions on how to choose proper identification methods and smoothing techniques according to input data.

Published: August 2024

Inhibiting the expression of spindle appendix cooled coil protein 1 (SPDL1) can slow down disease progression and is related to poor prognosis in patients with esophageal cancer. However, the specific roles and molecular mechanisms of SPDL1 in esophageal squamous cell carcinoma (ESCC) have not been explored yet. The current study aimed to investigate the expression levels of SPDL1 in ESCC via transcriptome analysis using data from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus databases. Moreover, the biological roles, molecular mechanisms, and protein networks involved in SPDL1 were identified using machine learning and bioinformatics. The cell counting kit-8 assay, EdU staining, and transwell assay were used to investigate the effects of inhibiting SPDL1 expression on ESCC cell proliferation, migration, and invasion. Finally, the correlation between the SPDL1 expression and cancer immune infiltrating cells was evaluated by analyzing data from the TCGA database. Results showed that SPDL1 was overexpressed in the ESCC tissues. The SPDL1 expression was related to age in patients with ESCC. The SPDL1 co-expressed genes included those involved in cell division, cell cycle, DNA repair and replication, cell aging, and other processes. The high-risk scores of SPDL1-related long non-coding RNAs were significantly correlated with overall survival and cancer progression in patients with ESCC (P < 0.05). Inhibiting the SPDL1 expression was effective in suppressing the proliferation, migration, and invasion of ESCC TE-1 cells (P < 0.05). The overexpression of SPDL1 was positively correlated with the levels of Th2 and T-helper cells, and was negatively correlated with the levels of plasmacytoid dendritic cells and mast cells. In conclusion, SPDL1 was overexpressed in ESCC and was associated with immune cells. Further, inhibiting the SPDL1 expression could effectively slow down cancer cell growth and migration. SPDL1 is a promising biomarker for treating patients with ESCC.

Authors: Opoku Felix Kwame , Owusu Nester Kumiwaa
Published: August 2024

The purpose of this study was to examine the effect of psychological well-being on job performance among nurses and midwives in rural and urban hospitals in Ghana amidst COVID-19. The study adopted a purely quantitative approach, using the explanatory research design. Data were collected from 262 nurses and midwives in two selected hospitals in the Central Region of Ghana. The Structural Equation Modelling was used to analyze the data collected. The results revealed that the levels of psychological well-being and job performance were high in both hospitals amidst the pandemic. Further, it was observed that although psychological well- being had significant influence on job performance among the nurses and midwives in both rural and urban communities, the effect was more significant in the urban settlements. Given these findings, the study recommended that in order to effectively improve the job performance of nurses and midwives, management must adopt policies such as, flexible work arrangements, leave policy, and counselling services to support their psychological well-being.

Published: August 2024

The National Institutes of Health (NIH) is the largest public research funder in the world. In an effort to make publicly funded data more accessible, the NIH established a new Data Management and Sharing (DMS) Policy effective January 2023. Though the new policy was available for public comment, the patient perspective and the potential unintended consequences of the policy on patients’ willingness to participate in research have been underexplored. This study aimed to determine: (1) participant preferences about the types of data they are willing to share with external entities, and (2) participant perspectives regarding the updated 2023 NIH DMS policy. A cross-sectional, nationally representative online survey was conducted among 610 English-speaking US adults in March 2023 using Prolific. Overall, 50% of the sample identified as women, 13% as Black or African American, and 7% as Hispanic or Latino, with a mean age of 46 years. The majority of respondents (65%) agreed with the NIH policy, but racial differences were noted with a higher percentage (28%) of Black participants indicating a decrease in willingness to participate in research studies with the updated policy in place. Participants were more willing to share research data with healthcare providers, yet their preferences for data sharing varied depending on the type of data to be shared and the recipients. Participants were less willing to share sexual health and fertility data with health technology companies (41%) and public repositories (37%) compared to their healthcare providers (75%). The findings highlight the importance of adopting a transparent approach to data sharing that balances protecting patient autonomy with more open data sharing.
Acquired resistance of Stenotrophomonas maltophilia to antimicrobials induced by herbicide paraquat dichloride

Stenotrophomonas maltophilia, a ubiquitous environmental bacterium, is an important cause of nosocomial infections. Although banned in some countries, paraquat (PQ) is commonly used to control weeds. In this study, we investigated the effects of increasing concentrations of PQ on S. maltophilia and its antimicrobial resistance. The sequential exposure of S. maltophilia K279a to increasing concentrations of PQ induces the formation of strains with increased resistance to PQ. Among the 400 PQ-resistant isolates tested, 70 clones were resistant to 16 μg/ml ciprofloxacin (CIP), and around 18% of the PQ/CIP-resistant isolates showed increased resistance to all the tested antimicrobials including, the aminoglycosides, quinolones, cephalosporin, chloramphenicol, and co-trimoxazole. The results of the expression analysis of the antimicrobial resistance genes in the five selected PQ/CIP-resistant isolates demonstrated the high expression of genes encoding efflux pumps (smeYZ, smaAB, smaCDEF, smeDEF, smeVWX, and smtcrA) and the enzymes aph(3’)-IIc, blaL1, and blaL2. However, expression of the genes known for PQ resistance (i.e., mfsA and sod) were not altered relative to the wild-type levels. Whole genome sequence analysis identified gene mutations that could account for the antimicrobial resistance, namely, smeT (TetR family regulatory protein), rplA (ribosomal protein L1), and acnA (aconitase A). Ectopic expression of wild-type AcnA partially complemented the fluoroquinolone-resistant phenotype of the mutant with mutated acnA, which suggests the role of aconitase A in antimicrobial susceptibility. Exposure of S. maltophilia to PQ thus induces the development of strains that increase resistance to multiple antimicrobials.
How to be acted upon by video games while (or without) losing the fun: The gaming world according to Davey Wreden
Authors: Nohr Rolf F.
Published: August 2024

In our actions in relation to computer games, we are rarely forced to reflect on the question of how we conceptualize the medial objects upon and with which we are acting. Do we understand computer games as products, as economically outlined goods that can only be negotiated on the basis of an inherent hegemonic ideology in terms of their manufacture, distribution and, above all, their application? Or do we view them as open texts or spaces of experience which we can assimilate and within which we can take effect in a resistant, emancipatory or dissident way, either selectively or continuously? Do we shape the game, or does the game shape us? In a nutshell: is it possible to appropriate computer games? Davey Wreden’s games and can help us investigate these questions.
From Muslim to Muselmann: Muted prisoner in Guantanamo comics
Authors: Santesso Esra Mirze
Published: August 2024

This article focuses on two Guantanamo comics, namely Tubiana and Franc’s Guantánamo Kid, and Mirk’s Guantanamo Voices: True Accounts from the World’s Most Infamous Prison to highlight a shift in comics in depictions of the Muslim Other, from the long-established trope of the ‘dangerous jihadi’ to the aggrieved, muted figure of the Muselmann. Subjected to torture, enhanced interrogation techniques, degradation and humiliation, the abject Muslim prisoner at Guantanamo gradually transforms into the ‘Muselmann’ – a term employed in Holocaust narratives to refer to the cadaveric and zombified existence of the broken prisoner. The characterization of the Muselmann in these two comics not only challenges the notion of the active, sinister, Muslim radical repeatedly featured in Western comics, but also demonstrates the vital role the medium plays in representing those who have lost the capacity to speak for themselves. As witness accounts, both texts aim to ‘unmute’ the Muselmann, even though their depiction of the abusive regimes in Gitmo is neither a redemptive nor an empowering act. Consequently, it falls on the comics reader to bear witness to the atrocities suffered by the Muselmann – not necessarily to restore justice, but at a minimum to recognize the Muslim prisoner’s humanity.
Evaluación de los estándares por la contabilidad
Authors: Arreghini Hugo Ricardo
Published: August 2024

El escrito está orientado a recordar la acción de la Contabilidad en su función de establecer estándares para determinar lo ocurrido periódicamente en la ejecución de los proyectos de una empresa y comprobar las causas del incumplimiento de esos planes. Esto tiene como propósito compararlos con los que normativamente se debieran respetar para dar satisfacción a condiciones normativas de responsabilidad socioambiental indicadas para su sostenibilidad.
Para encontrar respaldo en la teoría contable tradicional que se fundamenta universalmente en la razón económica de subsistir y crecer, se recurrió a manifestaciones de prestigiosos autores hechas hace algunas décadas.
Del análisis hecho para comprobar si era posible asociar las demostraciones que se logran contablemente al darles valor económico, al tratar de integrarlas con las derivaciones de la aplicación de normas de conducta preparadas para encauzar la conducta solidaria de la entidad, que deben someterse al arbitrio de la interpretación de un reglamento basado en la calificación socioambiental no cuantificable, resultó, como era previsible de antemano, que no hay compatibilidad entre ellas.

El fenómeno de masificación de los sistemas de educación superior genera procesos de diferenciación y desafíos considerables a las instituciones educativas. El presente artículo analiza la expansión reciente en el acceso a este nivel educativo en Argentina, y sus repercusiones en la configuración de este sistema. Se estudia la evolución en el período reciente de la oferta educativa de nivel superior (universitaria y no universitaria) según sector de gestión y región, a partir de los Anuarios Estadísticos que proporciona el Ministerio de Educación de la Nación. Asimismo, se analizan indicadores de acceso y graduación de los jóvenes según nivel socioeconómico del hogar y regiones a partir de información proveniente de la Encuesta Permanente de Hogares. Se destaca el aumento en la cobertura de educación superior (universitaria y no universitaria) principalmente en sectores socioeconómicos bajos y con particular intensidad en determinadas regiones del país. No obstante, se constata también una caída en la participación de los jóvenes que alcanzaron una titulación de nivel superior entre 2013 y 2022. Por último, el artículo ofrece algunas reflexiones sobre los desafíos en materia de planificación y coordinación para dar mejor respuesta a las demandas educativas y sociales futuras.
