Comparative benefits of environmental protection expenditures and environmental taxes in driving environmental quality of the European countries
Authors: Akdag Saffet , Yildirim Hakan , Alola Andrew Adewale
Published: April 2024

Environmental protection and tax policies are part of the crucial pillars and the evolving aspects of environmental sustainability drive. These policies are increasingly employed to counter the 21st century's global climate problem alongside providing economic relief for the implementing economies. Being on the frontier (i.e., the European Union [EU]) of these policies, the current study examines and compares the impacts of environmental protection expenditures and environmental tax on energy consumption on the ploy to mitigate greenhouse gas (GHG) emissions in the panel of EU member countries. With the use of system generalized method of moments and panel causality analyses, the study established the effectiveness of both environmental protection expenditure and environmental tax at improving environmental quality by respectively mitigating GHG emissions by elasticities of ~2.08 and ~0.18. Importantly, environmental protection expenditure is found to be about two times more effective at mitigating GHG emissions than environmental tax policy, thus providing a novel perspective in the literature. Moreover, energy intensity and Gross Domestic Product help to improve environmental quality by mitigating GHG emissions while population causes more pollutant effects. Additionally, the investigation reveals evidence of Granger causality from environmental protection expenditure to GHG emissions in seven of the EU countries and Granger causality from environmental tax to GHG emissions in 10 European countries. Notably, measurable dimensions of policy guidelines that are relevant for globally and/or nationally defined sustainable development goals are induced from the result of this investigation.

Published: April 2024

Spermatogenesis is critical for insect reproduction and the process is regulated by multiple genes. Glycosyltransferases have been shown to participate in the development of Drosophila melanogaster; however, their role in spermatogenesis is still unclear. In this study, we found that α1,4‐galactosyltransferase 1 (α4GT1) was expressed at a significantly higher level in the testis than in the ovary of Drosophila. Importantly, the hatching rate was significantly decreased when α4GT1 RNA interference (RNAi) males were crossed with w1118 females, with only a few mature sperm being present in the seminal vesicle of α4GT1 RNAi flies. Immunofluorescence staining further revealed that the individualization complex (IC) in the testes from α4GT1 RNAi flies was scattered and did not move synchronically, compared with the clustered IC observed in the control flies. Terminal deoxyribonucleotide transferase (TdT)‐mediated dUTP nick end labeling (TUNEL) assay showed that apoptosis signals in the sperm bundles of α4GT1 RNAi flies were significantly increased. Moreover, the expression of several individualization‐related genes, such as Shrub, Obp44a and Hanabi, was significantly decreased, whereas the expression of several apoptosis‐related genes, including Dronc and Drice, was significantly increased in the testes of α4GT1 RNAi flies. Together, these results suggest that α4GT1 may play dual roles in Drosophila spermatogenesis by regulating the sperm individualization process and maintaining the survival of sperm bundles.
The gut microbiome promotes locomotion of Drosophila larvae via octopamine signaling

Published: April 2024

The gut microbiome is a key partner of animals, influencing various aspects of their physiology and behaviors. Among the diverse behaviors regulated by the gut microbiome, locomotion is vital for survival and reproduction, although the underlying mechanisms remain unclear. Here, we reveal that the gut microbiome modulates the locomotor behavior of Drosophila larvae via a specific neuronal type in the brain. The crawling speed of germ‐free (GF) larvae was significantly reduced compared to the conventionally reared larvae, while feeding and excretion behaviors were unaffected. Recolonization with Acetobacter and Lactobacillus can fully and partially rescue the locomotor defects in GF larvae, respectively, probably due to the highest abundance of Acetobacter as a symbiotic bacterium in the larval gut, followed by Lactobacillus. Moreover, the gut microbiome promoted larval locomotion, not by nutrition, but rather by enhancing the brain levels of tyrosine decarboxylase 2 (Tdc2), which is an enzyme that synthesizes octopamine (OA). Overexpression of Tdc2 rescued locomotion ability in GF larvae. These findings together demonstrate that the gut microbiome specifically modulates larval locomotor behavior through the OA signaling pathway, revealing a new mechanism underlying larval locomotion regulated by the gut microbiome.

Published: April 2024

Background

Large‐vessel occlusion (LVO) stroke represents one‐third of acute ischemic stroke (AIS) in the United States but causes two‐thirds of poststroke dependence and >90% of poststroke mortality. Prehospital LVO stroke detection permits efficient emergency medical systems (EMS) transport to an endovascular thrombectomy (EVT)‐capable center. Our primary objective was to determine the feasibility of using a cranial accelerometry (CA) headset device for prehospital LVO stroke detection. Our secondary objective was development of an algorithm capable of distinguishing LVO stroke from other conditions.

Methods

We prospectively enrolled consecutive adult patients suspected of acute stroke from 11 study hospitals in four different U.S. geographical regions over a 21‐month period. Patients received device placement by prehospital EMS personnel. Headset data were matched with clinical data following informed consent. LVO stroke diagnosis was determined by medical chart review. The device was trained using device data and Los Angeles Motor Scale (LAMS) examination components. A binary threshold was selected for comparison of device performance to LAMS scores.

Results

A total of 594 subjects were enrolled, including 183 subjects who received the second‐generation device. Usable data were captured in 158 patients (86.3%). Study subjects were 53% female and 56% Black/African American, with median age 69 years. Twenty‐six (16.4%) patients had LVO and 132 (83.6%) were not LVO (not‐LVO AIS, 33; intracerebral hemorrhage, nine; stroke mimics, 90). COVID‐19 testing and positivity rates (10.6%) were not different between groups. We found a sensitivity of 38.5% and specificity of 82.7% for LAMS ≥ 4 in detecting LVO stroke versus a sensitivity of 84.6% (p < 0.0015 for superiority) and specificity of 82.6% (p = 0.81 for superiority) for the device algorithm (CA + LAMS).

Conclusions

Obtaining adequate recordings with a CA headset is highly feasible in the prehospital environment. Use of the device algorithm incorporating both CA and LAMS data for LVO detection resulted in significantly higher sensitivity without reduced specificity when compared to the use of LAMS alone.

Representation of skin carcinomas in public awareness – Awareness worldwide and in Germany
Authors: Meinzenbach Anne , Kaatz Martin , Springer Steffen , Zieger Michael
Published: April 2024

Background and objectives

In recent years, there has been an increase in skin cancer. The aim of this study was therefore to investigate the representation of skin cancer in public awareness worldwide and in Germany, and to determine whether Skin Cancer Awareness Month is represented in the search interests of the Internet‐using population in the same way as Breast Cancer Awareness Month worldwide.

Data and methods

In this study, Google Trends data were used to track levels of public awareness for different tumor entities and skin cancer types worldwide and for Germany.

Results

The results of this analysis clearly showed a high level of relative public search interest in breast cancer worldwide in the awareness month of October. Worldwide and in Germany, there was a certain increase in search interest and a certain seasonal effect around the May awareness month for skin cancer. For example, the analysis showed a search interest in May and during the summer months in Germany.

Conclusions

It is likely that the population, for example in Germany, may benefit further from an even greater emphasis on the topic of skin cancer.
Association cortical areas in the mouse contain a large population of fast‐spiking GABAergic neurons that do not express parvalbumin
Authors: Courcelles Erik Justin , Kjelsberg Kasper , Convertino Laura , Nair Rajeevkumar Raveendran , Witter Menno P. , Nigro Maximiliano José
Published: April 2024

GABAergic neurons represent 10–15% of the neuronal population of the cortex but exert a powerful control over information flow in cortical circuits. The largest GABAergic class in the neocortex is represented by the parvalbumin‐expressing fast‐spiking neurons, which provide powerful somatic inhibition to their postsynaptic targets. Recently, the density of parvalbumin interneurons has been shown to be lower in associative areas of the mouse cortex as compared with sensory and motor areas. Modelling work based on these quantifications linked the low‐density of parvalbumin interneurons with specific computations of associative cortices. However, it is still unknown whether the total GABAergic population of association cortices is smaller or whether another GABAergic type can compensate for the low density of parvalbumin interneurons. In the present study, we investigated these hypotheses using a combination of neuroanatomy, mouse genetics and neurophysiology. We found that the GABAergic population of association areas is comparable with that of primary sensory areas, and it is enriched of fast‐spiking neurons that do not express parvalbumin and were not accounted for by previous quantifications. We developed an intersectional viral strategy to demonstrate that the population of fast‐spiking neurons is comparable across cortical regions. Our results provide quantifications of the density of fast‐spiking GABAergic neurons and offers new biological constrains to refine current models of cortical computations.

Published: April 2024

Background

Gastric cancer (GC) continues to pose a significant global threat in terms of cancer‐related fatalities. Despite notable advancements in medical research and therapies, further investigation is warranted to elucidate its underlying etiology and risk factors. Recent times have witnessed an escalated emphasis on comprehending the role of the microbiota in cancer development.

Methods

This review briefly delves into recent developments in microbiome‐related research pertaining to gastric cancer.

Results

According to studies, the microbiota can influence GC growth by inciting inflammation, disrupting immunological processes, and generating harmful microbial metabolites. Furthermore, there is ongoing research into how the microbiome can impact a patient's response to chemotherapy and immunotherapy.

Conclusion

The utilization of the microbiome for detecting, preventing, and managing stomach cancer remains an active area of exploration.

Published: April 2024

Acne, a highly prevalent skin disease, can be particularly bothersome for patients of Asian background because of its impact on self‐confidence and social interactions. In addition to active acne lesions, some patients may develop sequelae such as scarring, macular/postinflammatory hyperpigmentation, or erythema. The tendency of Asian skin to develop sequelae because of its increased susceptibility to irritation, cultural preferences for lighter skin phototypes, and differences in skincare regimens may all contribute to the increased burden of acne. Moreover, many Asia‐Pacific countries do not have their own guidelines for acne management, and those that do often have no schedule in place for regular updates. In this article, we provide a critical review of the published guidance for the management of acne and its sequelae in the Asia‐Pacific region, identifying gaps in current recommendations that could be addressed to enhance standards of acne care in Asia‐Pacific countries. Along with highlighting the importance of a comprehensive skincare regimen to increase treatment efficacy and adherence, we discuss topical retinoids and retinoid combination options in the acne armamentarium that may be beneficial for sequelae prevention and management, such as adapalene 0.3% ± benzoyl peroxide 2.5%, tretinoin 0.05%, tazarotene 0.1%, and trifarotene 0.005%. In particular, trifarotene 0.005% has been observed to significantly reduce acne scar counts in a Phase 4 study. The recent data highlight the need to establish up‐to‐date guidance for acne and acne sequelae management in Asia‐Pacific countries to provide optimal care to Asian patients.
Association of Herpes simplex infection with significantly increased risk of head and neck cancer: real‐world evidence of about 500,000 patients
Authors: von Stebut Jennifer , Heiland Max , Preissner Robert , Rendenbach Carsten , Preissner Saskia
Published: April 2024

Background

The role of viral agents in the development of head and neck cancers has remained controversial. While markers of viral origin have been isolated from oral cancer tissues, a causative relationship has yet to be shown. The aim of this study was to evaluate the relationship between head and neck cancers and Herpes simplex virus, one of the most common viral infections of the oral orifice.

Methods

Here, we conducted a retrospective analysis of two age‐ and gender‐matched cohorts extracted from the real‐world database TriNetX on March 10th, 2023, each consisting of 249,272 patients with and without Herpes simplex infections (ICD‐10: B00). The diagnoses C00‐C14 were analyzed, and risk analysis and Kaplan‐Meier survival statics were computed.

Results

The strongest association was found for lip cancer (ICD‐10: C00) with a hazard ratio [HR (CI 95% low‐high)] of 3.08 (1.77–5.35). A significant association with HR of 1.17 (1.02–1.34) was found for the entire group of head and neck cancers. Confounders like smoking and alcohol dependence were considered using propensity score matching.

Conclusion

The surprisingly strong correlation with lip, oral cavity, and pharynx neoplasms sheds new light on supposedly harmless herpes simplex infections, suggesting them as a possible new factor for risk stratification.
Defending the Doctrine of the Mean Against Counterexamples: A General Strategy
Authors: Colgrove Nicholas
Published: April 2024

Aristotle's doctrine of the mean states that each moral virtue stands opposed to two types of vice: one of excess and one of deficiency, respectively. Critics claim that some virtues – like honesty, fair‐mindedness, and patience – are counterexamples to Aristotle's doctrine. Here, I develop a generalizable strategy to defend the doctrine of the mean against such counterexamples. I argue that not only is the doctrine of the mean defensible, but taking it seriously also allows us to gain substantial insight into particular virtues. Failure to take the doctrine seriously, moreover, exposes us to the risk of mistaking certain vices for virtues.
Fiscal institutions and racial equity: Determining the price of water
Authors: Albrecht Kate , Carroll Deborah A. , Kass Amanda , Michnick Jason , Wetmore Brooke
Published: April 2024

Municipal water utilities across the United States establish their own rate structures to cover operations, maintenance, depreciation, and outstanding debt repayment. Yet, little is known about how rates are determined to ensure equity and/or affordability. To identify sources of variation in residential drinking water rates, we examine municipalities in northeastern Illinois, 2015–2019. Controlling for water utility characteristics, billing structures, financial management, service quality, and demographic/socioeconomic factors, we find no statistically significant correlations between water rates and median household income or race when nonrevenue water from leaking infrastructure is considered, revealing relative racial equity in water pricing within these communities. A larger water distribution network, more water included in the base charge, and a greater number of months in the billing cycle are all associated with lower rates. Purchasing water through an individual or cooperative agreement, a greater proportion of nonrevenue water from leaking infrastructure, a higher minimum monthly base charge, and more revenue debt outstanding (while controlling for nonrevenue water) are all associated with higher rates. We also find a positive correlation between municipal sewer rates and drinking water rates that supports findings from prior research. Overall, our research aids in the development of public policy that ensures all households have access to affordable and safe drinking water to promote water equity and public health.
Study of optimal subalgebras, invariant solutions, and conservation laws for a Verhulst biological population model
Authors: Sharma Aniruddha Kumar , Arora Rajan
Published: April 2024

In this research, the (2+1)‐dimensional normal biological population model, incorporating the Verhulst law for population growth, is employed to explore species population dynamics. Employing Lie symmetry analysis, we address a nonlinear degenerate parabolic partial differential equation, yielding much‐improved results. This analysis includes computing one‐dimensional optimal subalgebras, reduced ordinary differential equations, and obtaining invariant solutions with a visual depiction of the physical behavior of the Verhulst biological population model through symmetry group transformations. Additionally, the multiplier method leads to novel conservation laws and potential systems not locally connected to the governing partial differential equation (PDE). These findings have significant implications for understanding and controlling biological populations, offering insights for applications in ecology and the environment.
Oscillatory and regularized shock waves for a modified Serre–Green–Naghdi system
Authors: Bolbot Daria , Mitsotakis Dimitrios , Tzavaras Athanasios E.
Published: April 2024

The Serre–Green–Naghdi equations of water wave theory have been widely employed to study undular bores. In this study, we introduce a modified Serre–Green–Naghdi system incorporating the effect of an artificial term that results in dispersive and dissipative dynamics. We show that the modified system effectively approximates the classical Serre–Green–Naghdi equations over sufficiently extended time intervals and admits dispersive–diffusive shock waves as traveling wave solutions. The traveling waves converge to the entropic shock wave solution of the shallow water equations when the dispersion and diffusion approach zero in a moderate dispersion regime. These findings contribute to an understanding of the formation of dispersive shock waves in the classical Serre–Green–Naghdi equations and the effects of diffusion in the generation and propagation of undular bores.
Mixed‐norm estimates via the helicoidal method
Authors: Benea Cristina , Muscalu Camil
Published: April 2024

We prove multiple vector‐valued and mixed‐norm estimates for multilinear operators in , more precisely for multilinear operators associated to a symbol singular along a ‐dimensional space and for multilinear variants of the Hardy‐Littlewood maximal function. When the dimension , the input functions are not necessarily in and can instead be elements of mixed‐norm spaces .

Such a result has interesting consequences especially when spaces are involved. Among these, we mention mixed‐norm Loomis‐Whitney‐type inequalities for singular integrals, as well as the boundedness of multilinear operators associated to certain rational symbols. We also present examples of operators that are not susceptible to isotropic rescaling, which only satisfy “purely mixed‐norm estimates” and no classical  estimates.

Relying on previous estimates implied by the helicoidal method, we also prove (non‐mixed‐norm) estimates for generic singular Brascamp‐Lieb‐type inequalities.

Published: April 2024

Traumatic brain injury (TBI) is a major cause of morbidity and mortality globally. We unveiled the diagnostic value of serum NLRP3, metalloproteinase‐9 (MMP‐9) and interferon‐γ (IFN‐γ) levels in post‐craniotomy intracranial infections and hydrocephalus in patients with severe craniocerebral trauma to investigate the high risk factors for these in patients with TBI, and the serological factors predicting prognosis, which had a certain clinical predictive value. Study subjects underwent bone flap resection surgery and were categorized into the intracranial infection/hydrocephalus/control (without postoperative hydrocephalus or intracranial infection) groups, with their clinical data documented. Serum levels of NLRP3, MMP‐9 and IFN‐γ were determined using ELISA kits, with their diagnostic efficacy on intracranial infections and hydrocephalus evaluated by receiver operating characteristic curve analysis. The independent risk factors affecting postoperative intracranial infections and hydrocephalus were analysed by logistic multifactorial regression. The remission after postoperative symptomatic treatment was counted. The intracranial infection/control groups had significant differences in Glasgow Coma Scale (GCS) scores, opened injury, surgical time and cerebrospinal fluid leakage, whereas the hydrocephalus and control groups had marked differences in GCS scores, cerebrospinal fluid leakage and subdural effusion. Serum NLRP3, MMP‐9 and IFN‐γ levels were elevated in patients with post‐craniotomy intracranial infections/hydrocephalus. The area under the curve values of independent serum NLRP3, MMP‐9, IFN‐γ and their combination for diagnosing postoperative intracranial infection were 0.822, 0.722, 0.734 and 0.925, respectively, and for diagnosing hydrocephalus were 0.865, 0.828, 0.782 and 0.957, respectively. Serum NLRP3, MMP‐9 and IFN‐γ levels and serum NLRP3 and MMP‐9 levels were independent risk factors influencing postoperative intracranial infection and postoperative hydrocephalus, respectively. Patients with hydrocephalus had a high remission rate after postoperative symptomatic treatment. Serum NLRP3, MMP‐9 and IFN‐γ levels had high diagnostic efficacy in patients with postoperative intracranial infection and hydrocephalus, among which serum NLRP3 level played a major role.
Progresismos de segunda generación: entre el gatopardismo y las reformas sociales como cimientos de la transformación. Miradas a los gobiernos de México, Argentina y Colombia
Authors: Jimenez Martin Carolina
Published: April 2024

Atravesamos tiempos de incertidumbres. La crisis mundial que asistimos desde 2007 y que se acentuó con la emergencia sanitaria derivada del SARS-COVID 19 ha golpeado con mucha intensidad las condiciones de existencia de las clases trabajadoras y los sectores populares y ha abierto importantes debates sobre los caminos para construir una salida. Los progresismos del siglo XXI, tanto los de primera como de segunda generación, no han estado ajenos a esta discusión. Por el contrario, han tomado un papel activo y en la mayoría de los casos se han volcado hacia la consigna de resolver la crisis. Entre las dos oleadas de gobiernos alternativos se advierten algunas diferencias, tanto de contexto, como de los desafíos que enfrentan. No es posible abordarlos desde una trayectoria de continuidad. No se trata simplemente de una segunda temporada de progresismos. Los segundos, en la mayoría, se enfrentan a unas derechas “recargadas”, a una crisis que cobra nuevos matices y a unas sociedades desesperanzadas y empobrecidas que vitalmente no dan más espera. Este artículo se interroga por las tendencias generales de política que han acompañado tres de estos gobiernos: Andrés Manuel López Obrador en México,  Alberto Fernández en Argentina y más recientemente Gustavo Petro en Colombia. Y si bien no se trata de presentar unas valoraciones exhaustivas, si busca identificar algunas cuestiones que permitan indicar trayectorias y tendencias generales del proceso político vivido y en curso.

Published: April 2024

La coyuntura política latinoamericana en general y de Sudamérica en particular, incentiva el análisis de los diversos procesos sociales, políticos y económicos que atraviesa la región en la actualidad, producto de dinámicas propias y factores sistémicos. En este contexto, el presente artículo, de carácter cualitativo, reflexiona sobre los dos ciclos que, por el momento, marcan la permanencia del MAS en el ejecutivo boliviano y en la montaña rusa del progresismo sudamericano: los mandatos de Evo Morales (2006-2019) y la presidencia en curso de Luis Arce. En términos de resultados, se identificaron los acontecimientos nodales, de orden doméstico, que son constitutivos de ambas administraciones, así como los contextos regionales propios de cada época. A modo de cierre, se hace una aproximación sobre los retos que enfrenta el binomio Arce-Choquehuanca, prestando especial atención a las disputas intrapartidarias.

Published: April 2024

Uno de los rasgos que ha distinguido a los gobiernos progresistas en la región es el uso de herramientas de democracia directa, empleadas para promulgar nuevas constituciones, para consultar en la toma decisiones públicas importantes y como herramientas de revocación de mandato. El uso de estas herramientas y sus implicaciones forman parte de las discusiones actuales sobre la representación democrática en la región y sobre la propia calidad democrática de los regímenes y gobiernos que las emplean. Particularmente la revocación de mandato se ha empleado en Venezuela (2004-2016), Bolivia (2008) y en México (2022); sin embargo, su ejercicio ha despertado preguntas acerca de las características de su implementación y su uso político, particularmente considerando que la demanda de participación política proviene del origen de los progresismos, esto es en su relación con movimientos sociales y políticos que los impulsaron. En este artículo se analizan los tres casos de referéndums revocatorios considerando el contexto político en el que se originaron y su correspondencia con las demandas de mayor participación política popular.
Giant Parametric Amplification of the Inverse Cotton–Mouton Effect in Antiferromagnetic Crystals
Authors: Zvezdin A. K. , Dubrovin R. M. , Kimel A. V.
Published: April 2024

The interaction of light with spins in a Heisenberg antiferromagnet with a negligibly low magnetic anisotropy as in RbMnF3 has been theoretically analyzed. In particular, an optical pump–probe experiment, where coherent terahertz magnons are excited by short pump laser pulses in the antiferromagnet and are then detected by a probe pulse delayed with respect to the pump pulse, has been simulated. It has been shown that the giant increase in the intensity of excitation of terahertz magnons under the influence of the inverse Cotton–Mouton effect occurs near parametric resonance, i.e., in the parametric instability region.

The generation of interband photon pairs with wavelengths near 0.5 and 1.6 μm in a photonic-crystal fiber under low-power cw optical pumping by a diode laser with a central wavelength of 0.8 μm has been experimentally demonstrated. It has been found that the generation rate of entangled photons under cw pumping is comparable with values obtained with pulsed pumping by a femtosecond Ti:sapphire laser if the average cw pump power is an order of magnitude higher than the average pulsed pump power. The reached rates of photon generation are ensured by the used photonic-crystal fiber with a small effective mode area and a special dispersion profile. The reached low noise in the output signal is ensured by the separation of carrier frequencies of generated photons into different spectral bands.

Published: April 2024

A method for the joint application of two coupled quantum memristors on a single 171Yb+ ion by using optical and radio-frequency transitions induced by resonant laser fields is proposed. As a result, coherent mapping of the input quantum state to the output state is created. The proposed method makes it possible to use only one ion to control statistical weights in two-layer perceptrons.

The researches of the structural and magnetic properties of the layered chalcogenide Fe4Co3Se8, which has a ferrimagnetic order below T = 196 K, have been performed by means of X-ray diffraction, magnetic susceptibility measurements, and 59Co nuclear magnetic resonance (NMR) spectroscopy. It is found that the effective magnetic moment of iron ions is μeff ≈ 5.90(5) μB. The components of the magnetic shift and electric field gradient tensors at the Co nuclei sites have been determined. The hyperfine field induced on Co nuclei from neighboring iron ions has been estimated from the temperature dependences of the shift and susceptibility in Fe4Co3Se8. It was also established that cobalt ions in Fe4Co3Se8, as well as in the Co7Se8 compound, do not have intrinsic magnetic moment, but they do have a moment induced from neighboring iron ions
$$\mu _{{{\text{eff}}}}^{{{\text{Co}}}}$$
≈ 0.36(4) μB, which decreases at the magnetic ordering to 0.07(1)μB due to mutual compensation of contributions from neighboring iron ions.

Interaction of a quantum particle with gravitational wave in modified gravity theory
Authors: Das Rakesh , Saha Anirban
Published: April 2024

We present the formal solution for a quantum mechanical particle responding to gravitational wave (GW) in the framework of modified theories of gravity (MTG) where, apart from the two standard tensorial modes of polarization of GW, we have considered an additional scalar mode. The presence of this longitudinal scalar mode makes it necessary to extend the usual two-dimensional description of matter-GW interaction to a three-dimensional one. Naturally this requires non-trivial changes in the quantum mechanical treatment which we elaborate in this paper.
On the Klein–Gordon oscillators in Eddington-inspired Born-Infeld gravity global monopole spacetime and a Wu–Yang magnetic monopole
Authors: Mustafa Omar , Soares A. R. , Pereira C. F. S. , Vitória R. L. L.
Published: April 2024

We consider Klein–Gordon (KG) particles in a global monopole (GM) spacetime within Eddington-inspired Born–Infeld gravity (EiBI-gravity) and in a Wu–Yang magnetic monopole (WYMM). We discuss a set of KG-oscillators in such spacetime settings. We propose a textbook power series expansion for the KG radial wave function that allows us to retrieve the exact energy levels for KG-oscillators in a GM spacetime and a WYMM without EiBI-gravity. We, moreover, report some conditionally exact, closed form, energy levels (through some parametric correlations) for KG-oscillators in a GM spacetime and a WYMM within EiBI-gravity, and for massless KG-oscillators in a GM spacetime and a WYMM within EiBI-gravity under the influence of a Coulomb plus linear Lorentz scalar potential. We report the effects of the Eddington parameter $$\kappa $$

Non-relativistic limit of the Mielke–Baekler gravity theory
Authors: Concha Patrick , Merino Nelson , Rodríguez Evelyn
Published: April 2024

In this paper, we present a generalized non-relativistic Chern–Simons gravity model in three spacetime dimensions. We first study the non-relativistic limit of the Mielke–Baekler gravity through a contraction process. The resulting non-relativistic theory contains a source for the spatial component of the torsion and the curvature measured in terms of two parameters, denoted by p and q. We then extend our results by defining a Newtonian version of the Mielke–Baekler gravity theory, based on a Newtonian like algebra which is obtained from the non-relativistic limit of an enhanced and enlarged relativistic algebra. Remarkably, in both cases, different known non-relativistic and Newtonian gravity theories can be derived by fixing the $$\left( p,q\right) $$

parameters. In particular, torsionless models are recovered for $$q=0$$

Machine Learning-Based Multiagent Control for a Bunch of Flexible Robots
Authors: Wang Jun , Zhang Jiali , Tavoosi Jafar , Shirkhani Mohammadamin
Published: April 2024

In this paper, two novel methodologies of employing machine learning (here, the type-2 fuzzy system) are presented to control a multiagent system in which the agents are flexible joint robots. In the previous methods, the static mode controller has been investigated, which has little flexibility and cannot measure all the states of the system, but in the method presented in this paper, we can eliminate these disadvantages. The control signal is consisting of feedback from the output and the estimated states of the system. In the first method, the control signal coefficients are calculated from the linear matrix inequality (LMI), followed by a type-2 fuzzy system that adds the compensation signal to the control signal. In the second method, the type-2 fuzzy system is directly used to estimate the control signal coefficients which do not employ LMI. Both methods have their disadvantages and benefits, so in general, one of these two methods cannot be considered superior. To prove the effectiveness of the two proposed methods, a topology with four robots has been considered. Both proposed methods have been evaluated for controlling the angle and speed of the robot link. Also, another simulation was made without using the fuzzy system to verify the importance of our methods. Simulation results indicate the proper efficiency of proposed methods, especially in presence of uncertainty in the system.
