description: The sharing economy, also known as the collaborative economy, is based on co-creation through networks in online environments and is driven by the need for sustainability, happiness, and financial gain (Hamari, 2016; Allee, 2003; Prahalad & Ramaswamy, 2004; Reuschl, 2022). But even if academics and managers are becoming more interested in it, travelers choose peer-to-peer lodging rental services (henceforth referred to as P2P lodging) for some reasons or circumstances that are still unclear (Lalicic & Weismayer, 2018; Sainaghi & Baggio, 2020). According to Sainaghi and Baggio (2020), Airbnb has emerged as the most popular trend in the hotel industry and one of the most successful sharing economy models. Scholars have analyzed Airbnb’s possible danger to the conventional hotel industry or come to the conclusion that it generates demand by giving travelers access to travel alternatives that they otherwise would not have had.

description: The triphasic aerobic extractive desulfurization of benzothiophene (BT) using an aqueous H8PV5Mo7O40 solution as catalyst and O2 as oxidant was investigated. A time-resolved analysis of all reaction products in the gas, organic and aqueous phase, is given. The organic sulfur in BT is mainly converted to sulfuric acid. Mass transport limitations can be excluded. The reaction orders are 1 with regard to BT, and 0.5 both for HPA-5 and O2. Calculated data derived from this mechanism with a power law kinetic approach show good agreement to the experimental data for conversions below 60 \%. At higher BT conversions, significant deviations are found, suggesting that acidic products formed in the BT oxidation affect the catalyst and therefore the initial kinetics of the BT oxidation.

Detection of a Possible Limit Leading to a Violation of Causality for Low-Mass Particles at Very High Energies

 

This study investigates the implications of Planck scales on the causality of low-mass particles at extremely high energies using a fractal approach to space-time. It proposes new dynamics for the fabric of space-time and their effects on special relativity, suggesting a convergence of physical values at the Planck scale with potential implications for quantum gravity and theories of everything.

 

Key Concepts:

- Planck Scales: The minimum scales of measurement for time and length, providing a discrete framework for examining space-time.

- Fractal Approach: Proposes self-similar, iterative properties for space-time metrics.

- Causality and Quantum Gravity: Suggests new dynamics that may affect current understandings of quantum gravity and special relativity.

 

Methods:

An iterative, self-similar approach to Planck-scale spacetime was explored using fundamental axioms and assumptions. The study examined the sequence behavior of fundamental physical constants and the implications of vacuum permittivity at the Planck scale.

 

Results:

1. Self-Similarity and Fractals: The study demonstrated the self-similar, fractal nature of fundamental constants, ensuring convergence to a limit value.

2. Vacuum Permittivity: The results showed theoretical frameworks for the fine structure constant and electromagnetic coupling at different iterations.

3. Light Cone Anomaly: Observations indicated an anomaly in very high-energy, low-mass particles, suggesting a second fermionic causality limit distinct from the speed of light.

4. Cosmological Implications: The properties of the vacuum at the Planck scale could provide new explanations for cosmic inflation, the Big Bang singularity, and the nature of dark matter and dark energy.

 

Discussion:

The study introduces the concept of a fractal, compact object at the Planck scale, challenging the conventional view of space-time limits and proposing new dynamics for the structure of space-time and quantum gravity. It explores the implications of these dynamics for the unification of fundamental forces, cosmology, and particle physics.

 

Future Research:

The study suggests several research avenues:

- Investigating the compatibility of fractal space-time with the holographic principle.

- Extending AdS/CFT correspondence to include fractal properties of conformal field theory.

- Detailed studies of the implications for quantum gravity.

- Examining the light-cone anomaly and possible second fermionic causality limit.

- Exploring cosmological implications and the potential link to dark matter and dark energy through fractal space-time.

 

This research provides a foundational step toward a deeper understanding of quantum gravity and the fundamental structure of the universe, proposing a significant shift in how we conceptualize space-time at the smallest scales.

description: In this paper, a novel algorithm for the determination of Walker damage in loaded disc springs is presented. The algorithm takes a 3D-scan of a disc spring, measured residual stresses, material parameters, and spring loads as inputs. It outputs a distribution of Walker damage over the surface area of the input disc spring. As the algorithm allows a fully automated determination of the Walker damage, it can be used by disc spring manufacturers to reduce the working time spent on this task by specialized engineers significantly. Compared to spreadsheet applications using analytical formulas and finite element models using idealized geometry, this approach offers a superior description of the stress states in disc springs.

description: Advances in observing methods and the advent of instruments such as SINFONI, GPI etc allow to simultaneously produce high contrast images (HCI) and extract high resolution spectra (HRS) of exoplanet targets. This has produced multispectral images of the targets making it possible to simultaneously use the image and spectral dimensions of such data. Such data has been used in detection and characterization of multiple systems such as PDS70 (Haffert et al 2020., Christiaens 2020 etc.), HD142527 (Christiaens 2019) etc. Advanced data science techniques have been proposed to improve the current detection limit taking advantage of the large feature set provided by multispectral imaging. Machine learning (ML) has had a particularly high success rate in the imaging domain (e.g Dahlquist et al 2021, Gomez Gonzales et al 2018). However ML has proven ineffective when using spectra alone (e.g Fisher et al 2020) owing to the a large number of spectral channels that do not contribute discriminatory features from the star. Therefore, dimensionality reduction have been suggested in order to effectively harness HRS data. Consequently, this project investigates if after reducing the dimensionality of HRS, will the spatial diversity provided by the HCI improve the detection limit. We use SDI cubes from SINFONI. This consist of the HD142527 data cube and an empty data cube with injected companions. We implement dimensionality reduction by replacing the spectral dimension with a relative velocity dimension and the pixel values with cross correlation (CCF) values This produces a spatial CCF map consisting of correlated and uncorrelated pixels. Naturally, pixels which contain spectra closer to the template that it is correlated with have a higher value. However, this map is still contaminated by noise correlations and field rotation. It has been proven that the application of derotation and STIM algorithms with appropriate thresholding (Pairet et al 2019) to a standard ADI cube produces a reliable detection map. In our case we replace the ADI cube with a CCF cube and apply derotation+STIM. Choice of an appropriate threshold converts this STIM map into a detection map The thresholding in the STIM map has been shown to be somewhat noise dependent. In order to now harness the power of ML to our project we will replace the STIM+thresholding with an appropriate noise independent ML algorithm and summarize the improvement in detectability.

Diet quality and nutraceutical supplementation for the ageing brain

description: The present thesis aimed to investigate the relationship between diet quality and nutraceutical supplementation --including vitamins, minerals, multinutrients and herbals --for both cognitive and mood outcomes in healthy, middle-aged adults with `optimal' and `sub-optimal' diets. This thesis provides empirical evidence that higher diet quality in mid-life is associated with better psychological outcomes and that the benefit of nutraceutical supplementation may be conditional on the support of a healthy diet. This thesis highlights the issues of self-selection bias in participant selection and the interdependency of nutrients which will have implications for how we measure and model nutrient effects in randomised trials.

description: An extensive survey conducted in the Saïss plain of Morocco during the 2017–2018 growing season revealed that 35 out of 50 apple and pear orchards were infested with a pathogen that causes the decline disease. Morphological and phylogenetic tree analyses using the cox II gene allowed us to identify the pathogen as Phytopythium vexans. Interestingly, no Phytophthora and Pythium species were isolated. The occurrence and prevalence of the disease varied between locations; the most infested locations were Meknes (100%), Imouzzer (83%), and Sefrou (80%). To fulfill Koch’s postulate, a greenhouse pathogenicity test was performed on the stem and collar of one-year-old healthy seedlings of apple rootstock M115. Symptoms similar to those observed in the field were reproduced in less than 4 months post-inoculation with root rot disease severity ranging from 70 to 100%. The survey results evidenced that apple rootstocks, soil type, and irrigation procedure may contribute significantly to the occurrence of the disease. The disease was most prevalent in drip water irrigation and sandy-clay soil on wild apple rootstock. Accordingly, a rational drip advanced watering system and good sanitation practices could eliminate water stagnation and help prevent the onset of this disease. It was concluded that Pp. vexans occurrence may be strongly influenced by irrigation mode and type of soil. Therefore, the obtained findings of this study could help to better understand the recurrence of this disease and to develop a reliable integrated strategy for its management.

description: Presentation given at Wellcome Centre for Integrative Neuroimaging departmental meeting ("WIN Wednesday") 16th September 2020. Title: WIN Open Neuroimaging Project: Introducing our tools and launching the Open WIN Community Abstract: One of WIN's core themes is to develop both the infrastructure and culture to support 'open neuroimaging' among its 250+ members. The first stage of this program was to develop the infrastructure necessary to support researchers in sharing their data, acquisition protocols, experimental tools and analysis code, in an open, transparent and reproducible manner. As this stage near completion, we enter the second phase of work to provide training and support, and increase uptake of this infrastructure. We hope to achieve this by formally establishing a community of expert users and contributors: The Open WIN Community.

 The Open WIN Community will be actively engaged to: (1) provide feedback on and contribute to the future infrastructure development and training materials; (2) develop policies, incentives and governance recommendations to promote open research practices; (3) identify barriers to "working open" and devise strategies to remove these barriers for ourselves and others; (4) promote open research practices their own labs and wider community, and empower others to work open. This mode of community engagement is based on the Mozilla Open Leadership Framework which promotes open and inclusive participation by design, to mobilise the community, solve shared problems and achieve shared goals.

 This presentation will demonstrate the Open WIN infrastructure currently under development, layout our plans for community engagement, outline why you might like to join the Open WIN community, and invite you to take part in our first community "hackathon" event to be held in October.

Publisher: name: MDPI

description: The conversion of solid fuels via gasification is a viable method to produce valuable fuels and chemicals or electricity while also offering the option of carbon capture. Fluidized bed gasifiers are most suitable for abundantly available low-rank coal. The design of these gasifiers requires well-developed kinetic models of gasification. Numerous studies deal with single aspects of char gasification, like influence of gas compositions or pre-treatment. Nevertheless, no unified theory for the gasification mechanisms exists that is able to explain the reaction rate over the full range of possible temperatures, gas compositions, carbon conversion, etc. This study aims to demonstrate a rigorous methodology to provide a complete char gasification model for all conditions in a fluidized bed gasifier for one specific fuel. The non-isothermal thermogravimetric method was applied to steam and CO2 gasification from 500 °C to 1100 °C. The inhibiting effect of product gases H2 and CO was taken into account. All measurements were evaluated for their accuracy with the Allan variance. Two reaction models (i.e., Arrhenius and Langmuir–Hinshelwood) and four conversion models (i.e., volumetric model, grain model, random pore model and Johnson model) were fitted to the measurement results and assessed depending on their coefficient of determination. The results for the chosen char show that the Langmuir–Hinshelwood reaction model together with the Johnson conversion model is most suitable to describe the char conversion for both steam and CO2 gasification of the tested lignite. The coefficient of determination is 98% and 95%, respectively.
Anomaly of the angular parameter of the Lorentz factor for low-mass particles at very high energy in special relativity.
Creators: name: DUPLAN, Christophe
Publisher: name: Zenodo
Year: 2024

description: Abstract

This study examines the possibility that Planck scales have an impact on the causality of very high-energy light particles. Using a Planck-scale fractal approach, new dynamics for the fabric of spacetime are proposed, with an impact on special relativity. The results indicate an emergence of the fine-structure constant of physical constants at the Planck scale, suggesting significant implications for quantum gravity and unified field theories.Key findings:

1. Fractal self-similarity: Iterative expression of physical constants such as ℏ, G and c reveals that the sequences tend towards zero, highlighting a bounded, compact structure indicative of fractal self-similarity.

2. Vacuum permissiveness: a fractal approach to vacuum permissiveness demonstrates that the fine structure constant α can be defined in a theoretical framework, potentially linking electromagnetic and gravitational interactions.

3. Light-cone anomaly: at very high energies, low-mass particles exhibit anomalies that suggest the existence of a secondary causal limit distinct from the speed of light c, which could imply new physics.

4. Cosmological implications: A simplified application of this anomaly leads to the hypothesis of a new class of object, gravitational topological solitons.Methodology:An iterative, self-similar approach was applied to Planck-scale spacetime using fundamental axioms and assumptions. The fundamental spacetime metric and zero-point energy Ω were considered as unified elements within a Planck space, facilitating a recursive process characteristic of fractals.Results:- Analysis of Planck-scale properties supports the notion of compact fractal structure, with implications for both quantum gravity and unified field theories.

- A requalification of the Planck length from a simple spatio-temporal limit to a granular fractal structure reveals an anomaly in low-mass, high-energy particles, suggesting a secondary causal limit.

- The study extends to cosmological scales, proposing a new evolution of black holes leading to the creation of gravitational topological solitons.Discussion:The findings suggest that Planck scales could act as a gateway to new physics, potentially impacting formulations of quantum gravity and theories attempting to unify fundamental forces. The study also proposes that space-time at the Planck scale might exhibit tiling properties, challenging traditional understandings of the uncertainty principle and offering a fresh perspective on space-time geometry.Conclusion:The study’s exploration of Planck-scale properties opens new avenues for research into quantum gravity and unified field theories. The proposed fractal nature of space-time at these scales may revolutionize our understanding of fundamental physics and cosmology.Keywords:Planck scales, causality, light particles, special relativity, quantum gravity, fractal space-time, cosmology, dark matter, dark energy.

Cosmological implications: A simplified application of this anomaly leads to the hypothesis of a new class of object, gravitational topological solitons.Methodology:An iterative, self-similar approach was applied to Planck-scale spacetime using fundamental axioms and assumptions. The fundamental spacetime metric and zero-point energy Ω were considered as unified elements within a Planck space, facilitating a recursive process characteristic of fractals.Results:- Analysis of Planck-scale properties supports the notion of compact fractal structure, with implications for both quantum gravity and unified field theories.

- A requalification of the Planck length from a simple spatio-temporal limit to a granular fractal structure reveals an anomaly in low-mass, high-energy particles, suggesting a secondary causal limit.

- The study extends to cosmological scales, proposing a new evolution of black holes leading to the creation of gravitational topological solitons.Discussion:The findings suggest that Planck scales could act as a gateway to new physics, potentially impacting formulations of quantum gravity and theories attempting to unify fundamental forces. The study also proposes that space-time at the Planck scale might exhibit tiling properties, challenging traditional understandings of the uncertainty principle and offering a fresh perspective on space-time geometry.Conclusion:The study’s exploration of Planck-scale properties opens new avenues for research into quantum gravity and unified field theories. The proposed fractal nature of space-time at these scales may revolutionize our understanding of fundamental physics and cosmology.Keywords:Planck scales, causality, low-mass particles, special relativity, quantum gravity, fractal space-time, cosmology, dark matter, hight energy.
Interaction between a steel minipile footing system and expansive soils

description: Expansive soils undergo alternate swelling and shrinkage upon seasonal moisture changes, causing distress and damage to light structures constructed on them and heavy financial loss. A newly-developed driven battered minipile group footing system may reduce such ground movement-induced stress and associated damage. It is a low-impact, cost-effective, excavation and concrete-free alternative to traditional footing systems; however, its widespread acceptance among professional engineers has been limited as no study examined the mechanism of footing-expansive soil interaction due to seasonal ground movements. Therefore, a full-scale field experiment and numerical study was performed to evaluate this footing's ability to resist expansive soil-induced movements.

description: The high energy radiation emitted by young stars can have a strong impact on their subsequent rotational evolution at later stages. This is because XEUV-driven photoevaporation is one of the major drivers of the dispersal of circumstellar disks, which surround all newly born stars during the first few million years of their evolution. Since the photoevaporative mass loss is mainly a function of stellar X-ray luminosity, the lifetimes of planet-forming disks are primarily set by the X-ray emission of their central star. Stellar rotation and X-ray activity are therefore tightly coupled, as the disk prevents the star from spinning up as it contracts through the disk-locking phase. Using a magnetic morphology-driven stellar spin-down model, we show that the disk-locking phase has a profound impact on the subsequent rotational evolution of young stars, which ultimately governs the amount of high-energy radiation received by newly formed planets. By assuming that the lifetimes of planet-forming disks are mainly determined by the X-ray luminosity of their central stars at young stages, we find that the bimodal rotation period distribution of a number of older open clusters, such as Pleiades or Praesepe, can be successfully recovered.

description: Background: This study aimed to evaluate the effects of a combination of aerobic-resistance training (CARET) and broccoli supplementation on dectin-1 levels and insulin resistance in men with type 2 diabetes mellitus (T2D). Methods: Forty-four males with T2D were randomly allocated to four groups (n = 11 each group): CARET + broccoli supplement (TS), CARET + placebo (TP), control + broccoli supplement (S), and control + placebo (CP). CARET was performed three days per week for 12 weeks. TS and S groups received 10 g of broccoli supplement per day for 12 weeks. All variables were assessed at baseline and 12 weeks. Results: Plasma dectin-1 levels were decreased in TS and TP groups compared with the CP group (p < 0.05). Cardiometabolic risk factors showed significant reductions in TP and TS groups compared to S and CP groups (p < 0.05). Conclusion: The combination of CARET and broccoli supplementation produced the largest improvements in insulin resistance and dectin-1 and other complications of T2D.

description: Malaria control relies on insecticides targeting the mosquito vector, but this is increasingly compromised by insecticide resistance, which can be achieved by elevated expression of detoxifying enzymes that metabolize the insecticide. In diploid organisms, gene expression is regulated both in cis, by regulatory sequences on the same chromosome, and by trans acting factors, affecting both alleles equally. Differing levels of transcription can be caused by mutations in cis-regulatory modules (CRM), but few of these have been identified in mosquitoes. We crossed bendiocarb resistant and susceptible Anopheles gambiae strains to identify cis-regulated genes that might be responsible for the resistant phenotype using RNAseq, and cis-regulatory module sequences controlling gene expression in insecticide resistance relevant tissues were predicted using machine learning. We found 115 genes showing allele specific expression in hybrids of insecticide susceptible and resistant strains, suggesting cis regulation is an important mechanism of gene expression regulation in Anopheles gambiae. The genes showing allele specific expression included a higher proportion of Anopheles specific genes on average younger than genes with balanced allelic expression.
