Neurophysiological measurements of planarian brain activity: a unique model for neuroscience research
Authors: Benita Orel , Nesher Nir , Shomrat Tal 
Published: July 2024

ABSTRACT
Planarians are well-known model organisms for regeneration and developmental biology research due to their remarkable regenerative capacity. Here, we aim to advocate for the use of planaria as a valuable model for neurobiology, as well. Planarians have most of the major qualities of more developed organisms, including a primal brain. These traits combined with their exceptional regeneration capabilities, allow neurobiological experiments not possible in any other model organism, as we demonstrate by electrophysiological recording from planaria with two heads that controlling a shared body. To facilitate planarian neuroscience research, we developed an extracellular multi-unit recording procedure for the planarians fragile brain (Dugesia japonica). We created a semi-intact preparation restrained with fine dissection pins, enabling hours of reliable recording, via a suction electrode. Here, we demonstrate the feasibility and potential of planarian neurophysiological research by characterizing the neuronal activity during simple learning processes and responses to various stimuli. In addition, we examined the use of linalool as anesthetic agent to allows recordings from an intact, large worm and for fine electrophysiological approaches such as intracellular recording. The demonstrated ability for neurophysiological measurements, along with the inherent advantages of planarians, promotes this exceptional model organism for neuroscience research.
Estimating Stockout Costs and Optimal Stockout Rates: A Case on the Management of Ugly Produce Inventory
Authors: Lim Stanley Frederick W. T. , Rabinovich Elliot , Lee Sanghak , Park Sungho 
Published: July 2024

Efficiently managing inventories requires an accurate estimation of stockout costs. This estimation is complicated by challenges in determining how to compensate consumers monetarily to ensure they will maintain the same level of utility they would have obtained had stockouts not occurred. This paper presents an analysis of these compensation costs as applied to the design of optimal stockout rates by an online retailer marketing to consumers aesthetically substandard fruits and vegetables rejected by mainstream grocery chains. Because growers face high uncertainty in their harvesting conditions and in the aesthetic quality of their crops and there are little data on hand to predict the value consumers attach to the availability of subpar produce, it is difficult to optimally match the supply of these products with consumers’ demand. Our analysis draws from a multiple discrete-continuous extreme value (MDCEV) choice model to calculate consumer compensations that the retailer can use to estimate the opportunity costs of stockouts to manage its inventory. We show that not taking into account these compensation costs could unduly inflate the optimal stockout rates for these products. Armed with these compensation cost estimates, we show how these costs can serve as incentives for retailers to source greater inventory amounts of imperfect produce from growers and how this will ultimately translate into less waste in the supply chain.

From Feeds to Inboxes: A Comparative Study of Polarization in Facebook and Email News Sharing
Authors: Yoganarasimhan Hema , Iakovetskaia Irina 
Published: July 2024

This study explores the polarization of news content shared on Facebook compared with email using data from the New York Times’ Most Emailed and Most Shared lists over 2.5 years. Employing latent Dirichlet allocation and large language models (LLMs), we find that highly polarized articles are more likely to be shared on Facebook (versus email), even after accounting for factors like topics, emotion, and article age. Additionally, distinct topic preferences emerge, with social issues dominating Facebook shares and lifestyle topics prevalent in emails. Contrary to expectations, political polarization of articles shared on Facebook did not escalate post-2020 election. We introduce a novel approach to measuring polarization of text content that leverages generative artificial intelligence models, like ChatGPT, and it is both scalable and cost effective. This research contributes to the evolving intersection of LLMs, social media, and polarization studies, shedding light on descriptive patterns of content dissemination across different digital channels.

Published: July 2024

La dieta de los primates tamarinos es predominantemente frugívora e insectívora, puede incluir otros elementos en su dieta como néctar, semillas y artrópodos, mientras que el consumo de vertebrados es ocasional. Se presenta un registro inédito de consumo de lagartijas neotropicales (Tropidurus sp.) por parte del tamarino pichico (Leontocebus weddelli) en Porto Velho, Rondônia, Brasil. El registro se realizó en el año 2022 en el campus José Ribeiro Filho de la Universidad Federal de Rondônia, la cual está situada en la zona periurbana, a 9.5 km de la ciudad de Porto Velho. Se utilizó el método ad libitum, registrando continuamente todos los aspectos conductuales importantes del primate. Se observó en el suelo a un individuo adulto de sexo indeterminado de Leontocebus weddelli, que durante aproximadamente 6 minutos consumió por completo a un individuo adulto de Tropidurus sp. Los representantes del género Leontocebus consumen frutas e insectos, y las lagartijas no son los principales ítems en su dieta, pero representan una importante fuente de energía. Esta nota refuerza el potencial adaptativo de este género, además de la exploración estacional de presas en entornos muy alterados.

En el bosque mesófilo de montaña (BMM) se reporta el 53 % de las especies de mamíferos de México. Los mamíferos han sido afectados negativamente por diferentes causas, y algunos están clasificados en categoría de riesgo. El objetivo del estudio fue conocer la riqueza y abundancia de una comunidad de mamíferos en un fragmento de BMM y una zona de restauración (ZR), en Huatusco, Veracruz, México. Se utilizó fototrampeo y búsqueda de huellas para el registro de mamíferos (septiembre 2019-mayo 2020). Se realizó un listado taxonómico incluyendo la categoría de riesgo (NOM-059-SEMARNAT-2010 y IUCN). Se comparó la riqueza de especies mediante curvas de acumulación de especies y se calculó un índice de similitud entre los tratamientos. Se registraron 15 especies: 13 mediante cámaras trampa y 2 por huellas. Destacan Leopardus wiedii (peligro de extinción/casi amenazada), Dasyprocta mexicana (peligro crítico), Potos flavus (amenazada), Galictis vittata (protección especial) y Mazama temama (especie cinegética). El BMM y la ZR presentaron 9 y 12 especies, con una completitud del 96 % y el 100 %, respectivamente, y una similitud de 63 %. Se determinó que la riqueza de especies en el área se ve complementada entre ambos tratamientos. En la ZR encontramos especies oportunistas, mientras que en el BMM especies con menor tolerancia a la perturbación. La presencia de carnívoros es un indicativo de la importancia de esta área para la conservación de los mamíferos.

Los inventarios de vida silvestre son herramientas para la investigación biológica que pueden fomentar la conciencia pública sobre temas ambientales. Este estudio proporciona información sobre los mamíferos medianos que deambulan por el Jardín de las Esculturas, un parque de 2 ha ubicado en la ciudad de Xalapa, Veracruz, México, en el que no se han llevado a cabo trabajos previos sobre mamíferos. Los datos se obtuvieron como parte de un proyecto de educación ambiental, a través de fototrampeo y entrevistas informales con los empleados del parque. Reportamos por primera vez un inventario de mamíferos medianos para este sitio. Se registraron un total de 5 órdenes, 7 familias y 10 especies, 8 de las cuales son fauna nativa. A pesar de no encontrarse en ninguna categoría de riesgo, la pérdida de áreas verdes y los conflictos socioambientales podrían eventualmente llevarlas a la extirpación, junto con sus funciones ecológicas. Los empleados reportaron diversos conflictos entre asentamientos humanos vecinos y las especies silvestres registradas. Nosotros destacamos la importancia de esta zona como parte del archipiélago de fragmentos de bosques de Xalapa, al tiempo que mencionamos la relevancia de diseñar programas de educación ambiental que tengan como fin el fomentar la conexión con las especies locales, la difusión de su biología y conservación.

En los últimos 5 años, el conocimiento de los murciélagos (Chiroptera) de Bolivia ha avanzado significativamente, adicionándose 10 especies y una lista actualizada para el país. A pesar de los avances en el conocimiento de la fauna de murciélagos, algunas especies han sido registradas por pocos especímenes de referencia (n < 8), tales como Peropteryx leucoptera (Emballonuridae), Gardnerycteris crenulatum y Lampronycteris brachyotis (Phyllostomidae). Aquí reportamos nuevos registros para estas especies que amplían sus distribuciones en Bolivia y señalamos datos morfométricos adicionales. La revisión incluye especímenes colectados y depositados en colecciones sistemáticas, realizamos comparaciones cualitativas y cuantitativas de variables externas y cráneo-dentales con las descripciones taxonómicas originales de las 3 especies. También compilamos y proyectamos en mapas las localidades correspondientes a registros históricos en Bolivia. Los nuevos registros representan extensiones de distribución a 10 provincias biogeográficas dentro de Bolivia. Los especímenes de P. leucoptera provienen de la región sureste del país. Para G. crenulatum y L. brachyotis presentamos el registro más austral y oriental en Bolivia, respectivamente. Los especímenes de P. leucoptera tienden a ser más pequeños que otros colectados en la región, mientras que los especímenes de G. crenulatum son ligeramente mayores que aquellos reportados en otros países. Los nuevos registros extienden entre 197 y 736 km los rangos geográficos conocidos para estas especies en Bolivia. Recomendamos incrementar los esfuerzos orientados a la actualización de las distribuciones de otras especies con escasos registros en Bolivia.
Mid-infrared supercontinuum generation in As2S3-circular photonic crystal fibers pumped by 4.5  µm and 6  µm femtosecond lasers
Authors: Chu Van Ben , Le Tran Bao Tran , Chu Van Lanh 
Published: July 2024

A study on As2S3 chalcogenide photonic crystal fiber (PCF) and its potential in supercontinuum generation (SCG) applications is presented. The designed fibers exhibit near-zero flattened chromatic dispersion, facilitating coherent and broad SCG utilizing femtosecond lasers at 4.5 and 6 µm wavelengths. A continuous spectrum spanning from 1.5 to 8 µm is achieved when the initial fiber is stimulated with an input power of 20 kW. With a pulse width of 100 fs and input power of 6 kW, the second fiber provides soliton-induced SCG with 2 to 15 µm spectral bandwidth. Furthermore, the integration of these large core diameter PCFs with high-power laser pulses guarantees the preservation of optical fiber integrity without damage. Consequently, these fibers hold promise for delivering SC spectra characterized by high power density, catering to a diverse range of practical applications including optical communications, spectroscopy, sensing, metrology, and calibration.
From localized to propagating surface plasmon resonances in Au nanoparticle-coated optical fiber sensors and its implications in biosensing

Nanoparticle-based plasmonic optical fiber sensors can exhibit high sensing performance, in terms of refractive index sensitivities (RISs). However, a comprehensive understanding of the factors governing the RIS in this type of sensor remains limited, with existing reports often overlooking the presence of surface plasmon resonance (SPR) phenomena in nanoparticle (NP) assemblies and attributing high RIS to plasmonic coupling or waveguiding effects. Herein, using plasmonic optical fiber sensors based on spherical Au nanoparticles, we investigate the basis of their enhanced RIS, both experimentally and theoretically. The bulk behavior of assembled Au NPs on the optical fiber was investigated using an effective medium approximation (EMA), specifically the gradient effective medium approximation (GEMA). Our findings demonstrate that the Au-coated optical fibers can support the localized surface plasmon resonance (LSPR) as well as SPR in particular scenarios. Interestingly, we found that the nanoparticle sizes and surface coverage dictate which effect takes precedence in determining the RIS of the fiber. Experimental data, in line with numerical simulations, revealed that increasing the Au NP diameter from 20 to 90 nm (15% surface coverage) led to an RIS increase from 135 to 6998 nm/RIU due to a transition from LSPR to SPR behavior. Likewise, increasing the surface coverage of the fiber from 9% to 15% with 90 nm Au nanoparticles resulted in an increase in RIS from 1297 (LSPR) to 6998 nm/RIU (SPR). Hence, we ascribe the exceptional performance of these plasmonic optical fibers primary to SPR effects, as evidenced by the nonlinear RIS behavior. The outstanding RIS of these plasmonic optical fibers was further demonstrated in the detection of thrombin protein, achieving very low limits of detection. These findings support broader applications of high-performance NP-based plasmonic optical fiber sensors in areas such as biomedical diagnostics, environmental monitoring, and chemical analysis.
A comprehensive survey of the home advantage in American football
Authors: Benz Luke , Bliss Thompson , Lopez Michael 
Published: July 2024

Abstract
The existence and justification to the home advantage – the benefit a sports team receives when playing at home – has been studied across sport. The majority of research on this topic is limited to individual leagues in short time frames, which hinders extrapolation and a deeper understanding of possible causes. Using nearly two decades of data from the National Football League (NFL), the National Collegiate Athletic Association (NCAA), and high schools from across the United States, we provide a uniform approach to understanding the home advantage in American football. Our findings suggest home advantage is declining in the NFL and the highest levels of collegiate football, but not in amateur football. This increases the possibility that characteristics of the NCAA and NFL, such as travel improvements and instant replay, have helped level the playing field.
Regulating Dominant Platforms: Challenges and Opportunities of Content Moderation on Jio Platforms
Authors: Chatterjee Arjun 
Published: July 2024

Abstract
Indian multinational technology company, Jio Platforms with an active subscriber base of 467.6 million (February 2024, Telecom Regulatory Authority of India data) continues to lead the market in India. Digitisation has transformed India’s governance model as deep penetration of telecom and the internet in India has laid the foundation for a digital economy. This article examines the role of self-regulation mechanisms and censorship in India’s dominant platform company Jio Platforms which contributes significantly to changing the paradigm of digital governance, thereby making services seamless, and easily accessible and improving the ease of living and doing business. Facebook’s investment in Jio for a 9.99 percent stake makes it the largest investment for a minority stake by a tech company anywhere in the world. With Jio Platforms and Facebook parent Meta Platforms rolling out a grocery delivery app using Meta’s WhatsApp messaging service, the transnational ties are deepening and expanding, making it imperative to examine the role of self-regulation and censorship in a market that is open, diverse and the largest in a democratic governance structure. This article will examine the key concerns of data sharing and privacy, especially when the central plank of government policy is digitisation. With stricter government regulations for foreign players in the market, there is a distinct focus of the government on boosting Indian companies to capture and control the market. Data collated by the Telecom Regulatory Authority of India (TRAI) show India’s overall internet user base grew to around 936.16 million in 2023. Such a diverse and vibrant open market calls for effective regulations and restrictions on privacy, algorithms, deceptive practices, antitrust, financing, and governance. This article aims to investigate the challenges of regulating dominant platforms. It delves deep into understanding and analysing the challenges and opportunities that evolve in regulating Jio Platforms. The study will also inquire whether favourable government policies and national legislation boost the processes of digitisation and whether there is a need for a new regulatory framework laid by the government for platforms to abide by. India has an open market dominated by US multinational firms, such as Facebook, YouTube, and Twitter. Content removal and other online censorship efforts are topics of heated debate, in academia and policy circles. This makes it arduous to ensure that data protection and privacy are safeguarded, particularly by dominant platforms such as Jio Platforms which is almost monopolising the Indian market.
Request for confirmation sequences in British and American English
Authors: Küttner Uwe-A. , Szczepek Reed Beatrice 
Published: July 2024

Abstract
This article presents the quantitative findings from a comparative study of request for confirmation (RfC) sequences in British English (BE) and American English (AE). The study is part of a large-scale cross-linguistic research project on RfCs in ten languages. RfCs put forward a proposition about which the speaker claims some knowledge but for which they seek (dis)confirmation from an informed co-participant. The article examines linguistic resources for building RfCs and their responses in the two English varieties. RfCs are analyzed with regard to their syntactic design, polarity, modulation, inference marking, connectives, question tags, and the prosodic design of confirmables and potential question tags. Responses to RfCs are analyzed with regard to response type, the use, type and position of response tokens, (non-)minimal responses in turns with a response token, response prefacing, and repeat responses. BE and AE are found to resemble each other closely in most categories. A major exception is their prosodic design, however. Specifically, the preference for the final pitch pattern of RfCs differs markedly in the two varieties: BE shows a strong preference for final falling pitch; AE shows a preference for final rising pitch. This suggests that the two varieties have routinized distinct intonation patterns for expressing epistemic (un)certainty in RfCs.
WHO to build neglect of RF-EMF exposure hazards on flawed EHC reviews? Case study demonstrates how “no hazards” conclusion is drawn from data showing hazards
Authors: Nordhagen Else K. , Flydal Einar 
Published: July 2024

Abstract
We examined one of the first published of the several systematic reviews being part of WHO’s renewed initiative to assess the evidence of associations between man-made radiofrequency electromagnetic radiation (RF-EMF) and adverse health effects in humans. The examined review addresses experimental studies of pregnancy and birth outcomes in non-human mammals. The review claims that the analyzed data did not provide conclusions certain enough to inform decisions at a regulatory level. Our objective was to assess the quality of this systematic review and evaluate the relevance of its conclusions to pregnant women and their offspring. The quality and relevance were checked on the review’s own premises: e.g., we did not question the selection of papers, nor the chosen statistical methods. While the WHO systematic review presents itself as thorough, scientific, and relevant to human health, we identified numerous issues rendering the WHO review irrelevant and severely flawed. All flaws found skew the results in support of the review’s conclusion that there is no conclusive evidence for nonthermal effects. We show that the underlying data, when relevant studies are cited correctly, support the opposite conclusion: There are clear indications of detrimental nonthermal effects from RF-EMF exposure. The many identified flaws uncover a pattern of systematic skewedness aiming for uncertainty hidden behind complex scientific rigor. The skewed methodology and low quality of this review is highly concerning, as it threatens to undermine the trustworthiness and professionalism of the WHO in the area of human health hazards from man-made RF-EMF.

Published: July 2024

AbstractMetal oxide nanostructures (MONSTRs) have become popular in various fields. This study investigates the durability of MONSTRs synthesized through hot water treatment (HWT) using copper, aluminum, and zinc as the source metals of choice. The physical durability tests include pressure, scratch, and scotch tape adhesion tests, and chemical durability tests such as corrosion resistance tests, heat resistance, and solar exposure tests. Results showed that MONSTRs synthesized from HWT are highly durable under the tested conditions except for NaOH and HCl immersion tests for copper oxide and zinc oxide. The study concluded that HWT is a sustainable synthesis method for MONSTRs.
