description: In this work we study a Horava-like five-dimensional model in the context of braneworld theory. To begin with, the equations of motion of such model are obtained and, within the realm of warped geometry, we show that the model is consistent if and only if $λ$ takes its relativistic value 1. Furthermore, since the first derivative of the warp factor is discontinuous over the branes, we show that the elimination of problematic terms involving the square of the warp factor second order derivatives are eliminated by imposing detailed balance condition in the bulk. Afterwards, the Israel's junction conditions are computed, allowing the attainment of an effective Lagrangian in the visible brane. In particular, for a (4+1)-dimensional Horava-like model defined in the bulk without cosmological constant, we show that the resultant effective Lagrangian in the brane corresponds to a (3+1)-dimensional Horava-like model with an emergent positive cosmological constant but without detailed balance condition. Now, restoration of detailed balance condition, at this time imposed over the brane, plays an interesting role by fitting accordingly the sign of the arbitrary constant $β$ that labels the extra terms in the model, insuring a positive brane tension and a real energy for the graviton within its dispersion relation. To end up with, the brane consistency equations are obtained and, as a result, we show that the detailed balance condition again plays an essential role in eliminating bad behaving terms and that the model admits positive brane tensions in the compactification scheme if, and only if, $β$ is negative, what is in accordance with the previous result obtained for the visible brane.

Gold electrode electrochemistry in protein based solar cells

description: The high quantum efficiency of photosynthetic reaction centers makes them candidates for use in solar energy harvesting devices. A bio-photovoltaic cell can be made by dissolving reaction centers and two mediators, such as quinone and cytochrome c, in the conductive electrolyte of an electrochemical cell. The mediators transfer the photo-generated charges to the electrodes upon illumination. So far such protein-based devices have shown low overall power conversion efficiency. Previously it has been shown that slow charge transfer limits the efficiency of these devices. Moreover, it has been observed that the cell response is dependent on the electrode materials and their interactions with the proteins and the mediators. In this thesis, the importance of the cleanliness of the system, the adsorption of two types of reaction centers: Wild-type and cysteineless, two mediators: quinone and cytochrome c, and detergents (used to make the reaction center water soluble) on a gold electrode are investigated. It is shown that common cleaning methods such as sonication in a mixture of deionized water and ethyl alcohol, sulfuric acid potential cycling, and piranha solution may not be practical and sufficient to remove the reaction centers and mediators from the electrodes and the container. Additionally, it is shown that eliminating oxygen can result in the reduction of unwanted parasitic reactions in the cell, which could lower the generated photocurrent and hence the overall efficiency of the cell. Therefore, new methods for cleaning and a new cell design are proposed and used throughout the experiments. Capacitance measurements, using cyclic voltammetry and AC voltammetry techniques, in the absence and the presence of each of the cell analytes suggest that unmodified reaction centers, detergents, and the mediators bind to the surface of the gold electrode irreversibly. Finally, it is shown that cysteineless reaction centers also adsorb irreversibly on the surface of the gold, demonstrating that cysteine S-Au bonding is not the only irreversible binding mechanism.

description: This paper addresses the relationship between vulnerability and climate change induced human population displacement. Anthropogenic climate change is increasingly altering the way people live. A significant consequence of the effects of climate change is human displacement due to climate effects such as hurricanes, sea level rise, and drought. People displaced by the effects of climate change suffer from a legal protection gap. Increasing global attention is being addressed at closing this gap. This paper explores the relationship between vulnerability and climate change induced displacement by analyzing case studies of hurricane induced displacement in the U.S. Gulf Coast, cyclone induced displacement in Bangladesh, and drought induced displacement in Somalia. Analysis of these case studies demonstrates that there is a relationship between socioeconomically vulnerable populations and displaced populations. Both in developed and developing countries, environmental displacement affects vulnerable populations disproportionately. Policy aimed at closing the legal protection gap for environmentally displaced persons should address the socioeconomic inequalities that make marginalized groups more vulnerable to climate change.

description: Antarctica is home to numerous species that are vulnerable to environmental change, and assessing species responses requires long-term monitoring. However, Antarctica’s extreme nature presents limitations to conducting the type of long-term or broad-scale studies necessary for understanding changes in community composition. In this paper, we evaluate the potential for the use of environmental DNA (eDNA) methods in expanding scientific research efforts for biodiversity monitoring and conservation genetics in Antarctica. Through a systematic literature review, we identify that most Antarctic eDNA studies have focused on microbial metabarcoding using samples from soil, sediment, snow, and water. Few eDNA studies in Antarctica have focused on vertebrate biodiversity or population genetics, but we highlight several examples that have effectively and creatively used eDNA to study vertebrates. We highlight the potential for the use of portable sequencing technologies in the future of Antarctic eDNA research. We conclude that eDNA could be a valuable tool for researchers in their efforts to assess, monitor, and conserve biodiversity in the Antarctic.

description: This paper demonstrates existence for all time of mean curvature flow in Minkowski space with a perpendicular Neumann boundary condition, where the boundary manifold is a convex cone and the flowing manifold is initially spacelike. Using a blowdown argument, we show that under renormalisation this flow converges towards a homothetically expanding hyperbolic solution.

description: Complex land use and land cover change (LULCC) processes modify ecosystems' ability to store and sequester carbon and regulate the climate, resulting in thermally uncomfortable climates and even more carbon emissions in an unchecked cycle. The value of potential loss of such climate ecosystem services remains understudied in urbanization planning and development. Using ecosystem modeling, this research quantifies potential changes of carbon storage and sequestration for a case of future LULCC in a tropical country by building an initial baseline carbon account of the existing forest. This study looked at a unique case of planned local-scale LULCC in Singapore where a secondary forest, Punggol Forest, is slated for conversion into a mixed-use residential neighborhood, Punggol Eco-Town. Carbon accounting is conducted to determine the carbon footprint of the LULCC, specifically for carbon storage and rate of carbon sequestration, using a sampled tree inventory with primary data collection. The results suggest that considerations of urban tree species selection in urban forestry are important in planning in order to reduce loss climate ecosystem services due to development. It is also a first step in using urban forestry tools for carbon accounting in decision-making for urban planning.

description: A fullerene graph is a cubic bridgeless plane graph with all faces of size 5 and 6. We show that that every fullerene graph on n vertices can be made bipartite by deleting at most sqrt{12n/5} edges, and has an independent set with at least n/2-sqrt{3n/5} vertices. Both bounds are sharp, and we characterise the extremal graphs. This proves conjectures of Doslic and Vukicevic, and of Daugherty. We deduce two further conjectures on the independence number of fullerene graphs, as well as a new upper bound on the smallest eigenvalue of a fullerene graph.

title: Fluorescent Technology Versus Visual and Tactile Examination in the Detection of Oral Lesion: A Pilot Study
Creators: name: Ayoub, Hadeel Mohammed
Publisher: name: Old Dominion University Libraries
Year: 2013

description: Purpose: The purpose of the study was to compare the effectiveness of the VELscope® Vx, versus a visual and tactile intraoral examination in detecting oral lesions in an adult, high risk population. Methods: A convenience sample of 30 participants (17 cigarette smokers and 13 dual addiction smokers) was enrolled. For the purpose of this study, dual addition was defined as cigarettes plus hookah usage. Two trained and calibrated dental hygienists conducted all examinations. Visual and tactile intraoral examinations were conducted, followed by VELscope® Vx florescence examinations. All subjects received an inspection of the lips, labial mucosa, buccal mucosa, floor of the mouth, dorsal, ventral and lateral sides of the tongue, as well as the hard and soft palate. Both evaluations took place in one visit. All participants received oral cancer screening information, recommendations and referrals for tobacco cessation programs and material on the two types of examinations provided. Results: Thirty subjects, between the ages 18-65 were enrolled (23 males and 7 females). The duration of tobacco use was significantly higher in cigarette smokers (14.1 years) than dual addiction smokers (5 years). The average numbers of cigarettes smoked per day were 13.5 compared to 14.2 cigarettes for dual addiction smokers. Neither the visual and tactile intraoral examination nor the VELscope® Vx examination showed any positive lesions. No lesions were detected; therefore, no referrals were made. Conclusion: Study participants were considered high risk based on demographics (current smokers & males). These results support data from the American Cancer Society, which indicates that males smoke more cigarettes than females, and are at a higher risk of oral cancer. Furthermore, individuals who have dual smoking addictions are on the rise, and are also at increased risk for oral cancer. Results from this study suggest the visual and tactile intraoral examination produced comparative results to the VELscope® Vx examination.

description: Fish reproducing in group-spawning aggregations face intense fisheries during spawning events due to increased ease of capture. Other traits often associated with group spawning, such as late sexual maturation and sequential hermaphroditism, cause group-spawning species to be especially vulnerable to population declines, either because fishermen target large, reproductively mature specimens or because they target juveniles that would otherwise have reached sexual maturity and contributed to reproduction. In group-spawning species that are protogynous hermaphrodites, including species of grouper, snapper, and the giant wrasse (Cheilinus undulates) fishing large specimens skews sex ratios towards females, thereby interfering with reproduction through sperm limitation. Unprecedented sex ratio skew could cause aggregations to disappear from their historical sites, with potential evolutionary implications. In this paper, I review the unique threats afflicting group-spawning species, as well as possible resolutions to these threats. I use the highly endangered humphead wrasse as a case study in the deleterious effects of overfishing on population dynamics, in the effectiveness of trade regulations and conservation strategies already in place, and in potential solutions not yet applied. Using the conclusions of this analysis, I extrapolate trends likely to continue in the Indo-Pacific region, where aggregation spawning is unfamiliar to fisheries scientists but familiar to local fishermen, and where aggregation-forming species are apt to benefit most from the implementation of effective conservation strategies.

description: This article examines the way the ‘anthropocentric-ecocentric’ dualism has come to bear on the history of the American presidency since the turn of the century, with special focus on three American Presidents, namely Theodore Roosevelt, Ronald Reagan, and Barack Obama. The major argument in this paper is that this duality constitutes not only a philosophical divergence of views, but also a determinant factor that has guided the beliefs, decisions, and policies of American presidents over more than a century. On account of their contradictory environmental records, both Theodore Roosevelt and Ronald Reagan are believed to stand for the two extremes of an ‘anthropocentrism-ecocentrism’ spectrum while Barak Obama ambivalently oscillates in the middle. Coming to power with different, sometimes conflicting, agendas, Presidents Roosevelt, Reagan, and Obama used the presidency as a bully pulpit to implement their ideological vision of nature, the environment, and economic growth in line with either ‘ecocentrism’ or ‘anthropocentrism.’ Focusing on their rhetoric and policies, this article highlights the three presidents’ differentiation along the ‘anthropocentric-ecocentric’ continuum and discusses the divergence of their respective political and philosophical beliefs as well as their implementation strategies. Ultimately, mapping the anthropocentric-ecocentric dualism in the history of American presidency provides a valuable insight into how this divide has been transferred from the philosophical realm to the political one.

description: Bees (Hymenoptera: Apoidea) are critical to crop production globally. In the last decade, significant declines in pollinator health have been documented and it is now widely considered a “crisis.” The potential causes of reduced pollinator health (species richness and abundance) relate to land-use decisions, practices, and management including habitat fragmentation, lack of foraging resources, pesticides, pests, and disease. Recent studies of native bees found diverse communities in cities around the world. This interdisciplinary pilot study investigates relationships between pollinator health and urban land-uses. It joins ecological and social science field research to examine linkages between native pollinator health and socio-cultural drivers of urban land-use decision-making practices to understand (1) what explains findings of diverse bee species in cities and (2) how citizens can encourage the enhancement of habitat for insect pollinator conservation. To establish a baseline for monitoring pollinator diversity and abundance, wild bees were sampled weekly at designated urban farms, community gardens, and prairie pockets located in St. Louis, Missouri, USA from 2013-2015. Ethnographic interviews were conducted in summer 2015 with 30 decision-makers to learn the social dynamics effecting management at the biologically sampled sites. Informants described bees’ role in crop yield, quality, and quantity; reported planting to attract pollinators; and spoke of the city as viable for pollinator habitat, which is relevant to urban conservation and policy. Their conversational evidence paired with images captured at the research sites reveal the rich urban social-ecological tapestry studied, as well as enhance and inform future research approaches.

description: Nickel (Ni) in ambient air may vary regionally with contributions from both natural processes and anthropogenic activities. Exposure to Ni compounds in ambient air above a certain level is associated with acute adverse effects, such as upper respiratory tract irritation, pneumonitis, and chronic adverse effects, such as respiratory cancer. Inhalation reference exposure standards are enacted in different jurisdictions to minimize exposures to ambient Ni above levels that can elicit adverse effects. This paper reports a guideline-/GLP-compliant study designed for setting inhalation exposure standards to protect from immunological effects associated with acute exposure to Ni. Female CD-1 mice were exposed via whole-body inhalation to aerosolized nickel chloride hexahydrate for 24-hr at nominal (vs. mean analyzed) concentrations of 20 (16), 50 (44) and 100 (81) µg Ni/m3. Host T-cell antibody immunological responses to intravenously-injected sheep red blood cells were then measured ex vivo in an Antibody-Forming Cell (AFC) assay. Exposure to the Ni substance significantly decreased spleen cell levels by 33%, but this was within biological variability for outbred mice. No concurrent decreases in spleen, thymus, or body weights were noted. No immunosuppression was observed with the Ni substance in the context of Total Spleen Activity [IgM AFC/spleen (× 103)] and Specific Activity [IgM AFC/spleen cells (× 106)]. Significant concentration-independent increases in Total Spleen Activity and Specific Activity seen with the nickel chloride hexahydrate were normal and within biological variability for outbred mice. In contrast, cyclophosphamide (positive control) significantly decreased spleen cell numbers, spleen and thymus weights, and abolished Specific Activity and Total Spleen Activity. Based on results here, an NOAEC of 81 µg Ni/m3 for immunosuppressive effects from inhaled nickel chloride hexahydrate was identified. It is hoped this value can be used to derive a reference standard for human exposure to ambient Ni.

description: Land degradation in drylands is the process in which undesirable conditions emerge due to human and natural causes. Despite the particularly deleterious effects of degradation, and it’s potentially irreversible nature, regional assessments have provided conflicting extents, rates, and severities of degradation, both globally and regionally. Current monitoring of degradation relies upon the detection of green, photosynthetically active parts of vegetation (e.g., leaves). Less is known, however, about the effect of degradation on the non-photosynthetic components of vegetation (e.g., wood, stems, leaf litter) and the relationship between photosynthetic vegetation (PV), non-photosynthetic vegetation (NPV), and bare soil under degraded conditions (BS). The major objective of the study was to evaluate regional patterns of fractional cover (i.e., PV, NPV, BS) under degraded and non-degraded NPP conditions in a managed rangeland in north Queensland, Australia. Homogenous environmental conditions were identified and each of NPP, PV, NPV, and BS were scaled according to their potential, reference values. We found a strong spatial and temporal correlation between scaled NPP with both scaled PV and scaled BS. Drastic differences were also found for PV and BS between degraded and non-degraded conditions. NPV displayed similarity to both PV and BS, however no clear relationship was found for NPV in all areas, irrespective of degradation conditions.
Systematic model-based optimal design and operation strategies of multistage and integrated continuous crystallisation processes

description: Crystallisation is an essential purification process in the pharmaceutical industry commonly operated in batch. Despite the recent progress in the adoption of continuous manufacturing in pharma, the development of effective continuous crystallisation processes remains very challenging due to the underlying complex kinetic phenomena and lack of systematic and rigorous design and optimisation strategies particularly in the case of multistage crystallisation and integrated processes. This thesis attempts to address some of the critical challenges using rigorous model-based design and optimisation strategies. The thesis firstly revisits the Attainable Regions methodologies to help design multistage crystallisation processes. The optimal dynamic performance of such processes received particular attention to propose for the first time effective optimal strategies for start-up, steady state, and shutdown to help reduce the transitions times (e.g., start-up time) and maximise on spec productions. In addition, the thesis addresses the case of continuous multiproduct manufacturing and proposes effective methodologies for product grade transition. The thesis also proposes a holistic methodology to help assess the performance of batch vs continuous to guarantee more reliable decision making. Finally, the thesis explores superstructure optimisation with recycles and in presence of impurities and provides key insights into the design of integrated reaction and crystallisation processes. Different optimal control, multi- objective, and mixed integer nonlinear optimization strategies were implemented along with multicriteria decision aiding to deliver a holistic approach starting from early design and sizing to the integration and optimal operation. Cooling antisolvent crystallization of Aspirin was used as a case study due to the underlying complexity of the system and its inherent large degrees of freedom. Many scenarios were considered to deliver the intended optimization objectives by manipulating large sets of decision variables including cooling profiles, antisolvent federate, seeding policies. The proposed methodologies shows that the start-up time of the multistage continuous crystallizer can be reduced by 78%, dynamic performance relevant of product grade transition can be improved by 90%.

description: Client-side JavaScript is being widely used in popular web applications to improve functionality, increase responsiveness, and decrease load times. However, it is challenging to build reliable applications using JavaScript. This work presents an empirical characterization of the error messages printed by JavaScript code in web applications, and attempts to understand their root causes. We find that JavaScript errors occur in production web applications, and that the errors fall into a small number of categories. In addition, we find that certain types of web applications are more prone to JavaScript errors than others. We further find that both non-deterministic and deterministic errors occur in the applications, and that the speed of testing plays an important role in exposing errors. Finally, we study the correlations among the static and dynamic properties of the application and the frequency of errors in it in order to understand the root causes of the errors.

description: Recent studies have shown that stormwater control measures (SCMs) are less effective at retaining phosphorus (P) than nitrogen. We compared P retention between two urban/suburban SCMs and their adjacent free-flowing stream reaches at the Baltimore Long-Term Ecological Study (LTER) site, and examined changes in P retention in SCMs across flow conditions. Results show that, when compared with free-flowing stream reaches, the SCMs had significantly lower dissolved oxygen (%DO) and higher P concentrations, as well as lower mean areal retention rates and retention efficiencies of particulate P (PP). In all the SCMs, concentrations of total dissolved phosphorus (TDP) consistently exhibited inverse correlations with %DO that was lower during summer base flows. Particulate phosphorus (PP) concentrations peaked during spring high flow period in both streams and in-line pond/SCMs, but they were also higher during summer base flows in suburban/urban SCMs. Meanwhile, PP areal retention rates and retention efficiencies of the SCMs changed from positive (indicating retention) during high flows to negative (indicating release) during low flows, while such changes across flow were not observed in free-flowing stream reaches. We attribute the changing roles of SCMs from a PP sink to a PP source to changes in SCM hydrologic mass balances, physical sedimentation and biogeochemical mobilization across flows. This study demonstrates that in suburban/urban SCMs, P retained during high flow events can be released during low flows. Cultivation of macrophytes and/or frequent sediment dredging may provide potential solutions to retaining both P and nitrogen in urban SCMs.

description: Central Business Districts (CBD) are areas of dense traffic which result in parking problems. Four parks were selected for detailed study in Akure, the capital of Ondo State, Nigeria. Parking surveys were conducted to evaluate their parking index (efficiency) using both close and open-ended questionnaires. Parking index (efficiency) for OFP1, OFP2, OFP3 and OFP4 were obtained as 42.5%, 69.52%, 74.88% and 26.66% respectively. The study shows that OFP1 and OFP4 operated below the maximum capacity at parking index lower than 50%, while OFP2 and OFP3 operated above the maximum capacity when compared with Policy 7 of the Parking Space Requirements in Parking Code Guidance 2012 of San Francisco Department of Transportation. Furthermore,50%, 36% and 14% of the respondents affirmed that the facilities are not adequate, adequate and very adequate respectively. Inadequacy in parking signage and deficiency in enforcement by Management was observed. However, effective communication, parking enforcement, operational efficiency and provision of parking signage should be adopted in the study area.
BACK TRANSLATION METHOD FOR TRANSLATION RAILWAY TERMINOLOGY AND COMPARING WITH OTHER METHODS
Creators: name: Pardayeva, Umida

Publisher: name: Zenodo
Year: 2025

description: The back translation method is essential for ensuring the accuracy and consistency of railway terminology across languages. This process involves translating a text into a target language and then translating it back into the original language by a different translator. In the railway sector, where precision is critical for safety, back translation helps verify translated terms, identify discrepancies, and enhance clarity. By maintaining terminological consistency and addressing cultural nuances, this method supports effective communication among international stakeholders, contributing to safer and more efficient railway operations.

description: Using archival XMM-Newton observations of the diffuse and unresolved components emission in the inner disc of M33 we exclude the possible contribution from narrow line emission in the energy range 0.5-5 keV more intense than 10^{-6}-10^{-5} erg/s. Under the hypothesis that sterile neutrinos constitute the majority of the dark matter in M33, we use this result in order to put constraints on their parameter space in the 1-10 keV mass range.

description: This paper critically evaluates different models of economic progress and development using concepts based on the idea of the ‘political economy’. It explores the influence of globalization on these different models and explores the nexus between the International Financial Institutions, trade bodies, and agreements that continuously exert economic pressure on governments. This paper also attempts to understand the environment and society in the context of markets and valuation mechanisms, and questions the effectiveness of economic instruments used to tackle complex environmental issues such as climate change and deforestation. The rest of this paper focuses on the technology-market interface; technologically oriented economic solutions seem to have a limited understanding of the root causes of the issues they are created to remedy. They also fail to acknowledge the intricate relationship between humans and their environments. This paper expounds the perceived inability of conventional economic frameworks to capture the dynamism, complex interactions, and organic nature of life sustaining phenomena in the biosphere is emphasized.

description: The cluster state represents a highly entangled state which is one central object for measurement-based quantum computing. Here we study the robustness of the cluster state on the two-dimensional square lattice at zero temperature in the presence of external magnetic fields by means of different types of high-order series expansions and variational techniques using infinite Projected Entangled Pair States (iPEPS). The phase diagram displays a first-order phase transition line ending in two critical end points. Furthermore, it contains a characteristic self-dual line in parameter space allowing many precise statements. The self-duality is shown to exist on any lattice topology.

Fractional Effective Charges and Misner-Wheeler Charge without Charge Effect in Metamaterials

description: Transformation optics enables engineering of the effective topology and dimensionality of the optical space in metamaterials. Nonlinear optics of such metamaterials may mimic Kaluza-Klein theories having one or more kinds of effective charges. As a result, novel photon blockade devices may be realized. Here we demonstrate that an electromagnetic wormhole may be designed, which connects two points of such an optical space and changes its effective topological connectivity. Electromagnetic field configurations, which exhibit fractional effective charges, appear as a result of such topology change. Moreover, such effects as Misner-Wheeler “charge without charge” may be replicated.

description: We use a simple fragmentation model to describe the statistical behavior of the Voronoi cell patterns generated by a set of points in 1D and in 2D. In particular, we are interested in the distribution of sizes of these Voronoi cells. Our model is completely defined by two probability distributions in 1D and again in 2D, the probability to add a new point inside an existing cell and the probability that this new point is at a particular position relative to the preexisting point inside this cell. In 1D the first distribution depends on a single parameter while the second distribution is defined through a fragmentation kernel; in 2D both distributions depend on a single parameter. The fragmentation kernel and the control parameters are closely related to the physical properties of the specific system under study. We use our model to describe the Voronoi cell patterns of several systems. Specifically, we study the island nucleation with irreversible attachment, the 1D car parking problem, the formation of second-level administrative divisions, and the pattern formed by the Paris Métro stations.

Newcastle Disease Virus as a Vaccine Vector for Development of Human and Veterinary Vaccines

description: Viral vaccine vectors have shown to be effective in inducing a robust immune response against the vaccine antigen. Newcastle disease virus (NDV), an avian paramyxovirus, is a promising vaccine vector against human and veterinary pathogens. Avirulent NDV strains LaSota and B1 have long track records of safety and efficacy. Therefore, use of these strains as vaccine vectors is highly safe in avian and non-avian species. NDV replicates efficiently in the respiratory track of the host and induces strong local and systemic immune responses against the foreign antigen. As a vaccine vector, NDV can accommodate foreign sequences with a good degree of stability and as a RNA virus, there is limited possibility for recombination with host cell DNA. Using NDV as a vaccine vector in humans offers several advantages over other viral vaccine vectors. NDV is safe in humans due to host range restriction and there is no pre-existing antibody to NDV in the human population. NDV is antigenically distinct from common human pathogens. NDV replicates to high titer in a cell line acceptable for human vaccine development. Therefore, NDV is an attractive vaccine vector for human pathogens for which vaccines are currently not available. NDV is also an attractive vaccine vector for animal pathogens.
Three-dimensionality in quasi-two dimensional flows: recirculations and barrel effects
Creators: name: Pothérat, Alban

Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: A scenario is put forward for the appearance of three-dimensionality both in quasi-2D rotating flows and quasi-2D magnetohydrodynamic (MHD) flows. We show that 3D recirculating flows and currents originate in wall boundary layers and that, unlike in ordinary hydrodynamic flows, they cannot be ignited by confinement alone. They also induce a second form of three-dimensionality with quadratic variations of velocities and current across the channel. This scenario explains both the common tendency of these flows to two-dimensionality and the mechanisms of the recirculations through a single formal analogy covering a wide class of flow including rotating and MHD flows. These trans-disciplinary effects are thus active in atmospheres, oceans or the cooling blankets of nuclear fusion reactors.

Ray Time Theory (RTT) – Time, Gravity and Dimensions

description: Ray Time Theory (RTT)}, proposed by Alessandro Rosti, is based on the idea that time is not a passive coordinate but a fundamental informational wave field. The temporal wavelength determines the perceived dimensional structure of spacetime. From a foundational informational Lagrangian, RTT unifies General Relativity and Quantum Mechanics within a single coherent framework, where gravity, dark matter, and dark energy emerge as geometric effects of temporal propagation.

RTT provides new insights into previously unexplained phenomena: galactic rotation curves are seen as the result of extradimensional temporal influences; dark matter is reinterpreted as a projection of informational tension distributed over; the Hubble constant and gravitational waves are reframed as residuals and reverberations of the global temporal field. In this vision, time does not flow — it propagates — and with it expands the fabric of the universe. The theory is testable via numerical simulations and observational data, offering a bold and verifiable alternative to standard cosmological models. The theory predicted deviations in Euclid data before the day of the first press conference (march 17th 2025).
