description: We present an analysis of an $f(T, \mathcal{T})$ extension of the Teleparallel Equivalent of General Relativity, where $T$ denotes the torsion and $\mathcal{T}$ the trace of the energy-momentum tensor. This extension includes non--minimal couplings between torsion and matter. In particular, we construct two specific models that recover the usual continuity equation, namely, $f(T, \mathcal{T})=T+g(\mathcal{T})$ and $f(T, \mathcal{T})=T\times g(\mathcal{T})$. We then constrain the parameters of each model by fitting the predicted distance modulus to that measured from type Ia supernovae, and find that both models can reproduce the late--time cosmic acceleration. We also observe that one of the models satisfies well the observational constraints and yields a goodness--of--fit similar to the $Λ$CDM model, thus demonstrating that $f(T,\mathcal{T})$ gravity theory encompasses viable models that can be an alternative to $Λ$CDM.

description: In crop production, the threats of soilborne pathogens, disease epidemics, climate change, high cost of chemical (nematicides and fungicides), development of chemical resistance and new disease outbreaks are increasing worldwide. Soil borne pathogen and plant-parasite nematodes difficult to manage once they established in soil. Many chemical fumigants effectively suppress pathogen, but most of the compounds are harmful to the environment. Biofumigants can be an option for disrupting disease and nematode life cycle. The use of Cole and other Brassica crops residues as biofumigants has emerged as an environment friendly alternative to prevention of soil borne pest diseases and chemical soil fumigation treatment.

description: The IoT is getting more and more pervasive. Even the simplest devices, such as a light bulb or an electrical plug, are made "smart" and controllable by our smartphone. This paper describes the findings obtained by applying the PETIoT kill chain to conduct a Vulnerability Assessment and Penetration Testing session on a smart bulb, the Tapo L530E by Tp-Link, currently best seller on Amazon Italy. We found that four vulnerabilities affect the bulb, two of High severity and two of Medium severity according to the CVSS v3.1 scoring system. In short, authentication is not well accounted for and confidentiality is insufficiently achieved by the implemented cryptographic measures. In consequence, an attacker who is nearby the bulb can operate at will not just the bulb but all devices of the Tapo family that the user may have on her Tapo account. Moreover, the attacker can learn the victim's Wi-Fi password, thereby escalating his malicious potential considerably. The paper terminates with an outline of possible fixes.
Backward transfer entropy: Informational measure for detecting hidden Markov models and its interpretations in thermodynamics, gambling and causality

description: The transfer entropy is a well-established measure of information flow, which quantifies directed influence between two stochastic time series and has been shown to be useful in a variety fields of science. Here we introduce the transfer entropy of the backward time series called the backward transfer entropy, and show that the backward transfer entropy quantifies how far it is from dynamics to a hidden Markov model. Furthermore, we discuss physical interpretations of the backward transfer entropy in completely different settings of thermodynamics for information processing and the gambling with side information. In both settings of thermodynamics and the gambling, the backward transfer entropy characterizes a possible loss of some benefit, where the conventional transfer entropy characterizes a possible benefit. Our result implies the deep connection between thermodynamics and the gambling in the presence of information flow, and that the backward transfer entropy would be useful as a novel measure of information flow in nonequilibrium thermodynamics, biochemical sciences, economics and statistics.

description: Nowadays, humanity finds itself in one of the most critical pathways regarding the sector of energy security. This epoch of 21st century is characterized from phenomena such as the vast increase of world population, that leads to a growing energy demand, which is answered mainly in fossil fuels. Because of the relative depletion of the conventional oil and gas reserves, the global oil and gas industry has turned its attention to exploring and uncovering new unconventional deposits. This is the category in which the gas hydrates deposits belong to. Deposits of this type can contribute to a percentage to the global energy mix if, of course, the appropriate conditions exist in terms of economic and technical feasibility. The natural concentrations of gas hydrates with methane as the predominant component, are estimated to have higher energy efficiency than the rest of oil and gas deposits. With the possibility of exploiting only a small part of these deposits, the coverage of the energy demand would be feasible for several years. The purpose of this dissertation is the documented presentation of techniques and technologies for the exploitation of gas hydrates deposits, as well as a further analysis of the general characteristics of these natural concentrations.

description: We study the zero-temperature limit of the Gibbs measures of a class of long-range potentials on a full shift of two symbols $\{0,1\}$. These potentials were introduced by Walters as a natural space for the transfer operator. In our case, they are locally constant, Lipschitz continuous or, more generally, of summable variation. We assume there exists exactly two ground states: the fixed points $0^\infty$ and $1^\infty$. We fully characterize, in terms of the Peierls barrier between the two ground states, the zero-temperature phase diagram of such potentials, that is, the regions of convergence or divergence of the Gibbs measures as the temperature goes to zero.

description: We determine the anomalous dimensions of baryon operators for the three color theory as function of the number of massless flavours within the conformal window to the maximum known order in perturbation theory. We show that the anomalous dimension of the baryon is controllably small, within the $δ$-expansion, for a wide range of number of flavours. We also find that this is always smaller than the anomalous dimension of the fermion mass operator. These findings challenge the partial compositeness paradigm.

description: Scientific literacy has become central to science education and science education research several decades now. Although there may be different views about the meaning of the term, there is a broad consensus that scientific literacy includes an adequate understanding about the nature of science (NOS). NOS seems to be a hard topic for students and teachers. A popular approach to NOS teaching and learning is the ‘general aspects conceptualization of NOS’, which is based on conceptualizing NOS through partial, general aspects that may refer to the nature of scientific inquiry and the nature of scientific knowledge. These aspects are often introduced to students in a contextualized way, thus they may be integrated in lessons based on current scientific work. One way to do it is through news articles with scientific content. In our study, 16 educational sciences students were engaged in small-group and whole-class discussions in order to collaboratively respond to questions about issues raised in a news-based text highlighting the influence of the COVID-19 pandemic on scientific research. Our results showed that the social embeddedness of science as well as the tentativeness of scientific knowledge and the creativity needed for its production, were successfully illustrated by the students.

Tunneling from a Minkowski vacuum to an AdS vacuum: A new thin-wall regime

description: Using numerical and analytic methods, we study quantum tunneling from a Minkowski false vacuum to an anti-de Sitter true vacuum. Scanning the parameter space of theories with quartic and non-polynomial potentials, we find that for any given potential tunneling is completely quenched if gravitational effects are made sufficiently strong. For potentials where $ε$, the energy density difference between the vacua, is small compared to the barrier height, this occurs in the thin-wall regime studied by Coleman and De Luccia. However, we find that other potentials, possibly with $ε$ much greater than the barrier height, produce a new type of thin-wall bounce when gravitational effects become strong. We show that the critical curve that bounds the region in parameter space where the false vacuum is stable can be found by a computationally simple overshoot/undershoot argument. We discuss the treatment of boundary terms in the bounce calculation and show that, with proper regularization, one obtains an identical finite result for the tunneling exponent regardless of whether or not these are included. Finally, we briefly discuss the extension of our results to transitions between anti-de Sitter vacua.

title: Movements of care: an ethnography of care relations composed by Emberá Dobidá migrants, Colombi
Creators: name: Faure, Agathe Elise
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2026

description: Drawing on twenty months of fieldwork conducted with Emberá Dobidá women and their extended households in Colombia, this thesis examines the connection between movement of people and the relations of care they compose. The Emberá Dobidá had in the past followed a mobile lifestyle, constantly moving between relatively permanent households and settlements, scattered across the rainforest of the Chocó. There, they gathered temporarily to ‘care’, cuidar in Spanish or acüi in Emberá Bedea, for one another. Small gestures of giving and receiving made what my interlocutors called ‘good energies’, which further influenced people into reciprocating their care and ultimately linked Emberá Dobidá people across time and space. Credited with specific bodily abilities, Emberá Dobidá women have historically played a key role in sustaining the circulation of care and the composition of these good energies. Yet recent historical events impacting Emberá Dobidá movement have affected their practices of care as well as women’s role in their maintenance. This has resulted in the rise of what my interlocutors called ‘bad energies’ and provoked a general sense of decline in how the Emberá Dobidá people manage social relations today. Focusing on Emberá Dobidá women who recently moved from the Indigenous territories of Chocó department to settle in the slums of Medellín, this thesis aims to account for how these women recompose relationships of care to face a moment of crisis but also to accommodate new aspirations. In doing so the thesis contributes to social scientific understandings of care circulation between transnational women migrants and their kin left at home, extending the literature on this theme by attending to relations of care made in non-kinship realms, as well as to nontransnational borders and the intricate logic of reciprocal circulation. Tracing the relation between movement and care eventually yields an approach to each concept as contextually embedded and culturally specific.

SQL Access Patterns for Optimistic Concurrency Control

description: Transaction processing is of growing importance for mobile and web applications. Booking tickets, flight reservation, e-Banking, e-Payment, and booking holiday arrangements are just a few examples. Due to temporarily disconnected situations the synchronization and consistent transaction processing are key issues. To avoid difficulties with blocked transactions or communication loss several authors and technology providers have recommended to use Optimistic Concurrency Control (OCC) to solve the problem. However most vendors of Relational Database Management Systems (DBMS) implemented only locking schemes for concurrency control which prohibit the immediate use of OCC. We propose Row Version Verifying (RVV) discipline to avoid lost updates and achieve a kind of OCC for those DBMS not providing an adequate non-blocking concurrency control. Moreover, the different mechanisms are categorized as access pattern in order to provide programmers with a general guideline for SQL databases. The proposed SQL access patterns are relevant for all transactional applications with unreliable communication and low conflicting situations. We demonstrate the proposed solution using mainstream database systems like Oracle, DB2, and SQLServer.

description: Catalytically active Janus particles suspended in solution create gradients in the chemical composition of the solution along their surfaces, as well as along any nearby container walls. The former leads to self-phoresis, while the latter gives rise to chemi-osmosis, providing an additional contribution to self-motility. Chemi-osmosis strongly depends on the molecular interactions between the diffusing chemical species and the wall. We show analytically, using an approximate "point-particle" approach, that by chemically patterning a planar substrate one can direct the motion of Janus particles: the induced chemi-osmotic flows can cause particles to either "dock" at the chemical step between the two materials, or to follow a chemical stripe. These theoretical predictions are confirmed by full numerical calculations. Generically, docking occurs for particles which tend to move away from their catalytic caps, while stripe-following occurs in the opposite case. Our analysis reveals the physical mechanisms governing this behavior.

description: In November 2023 the Paul Mellon Centre for Studies in British Art (PMC) acquired a unique digital resource on English stained glass and church architecture of the nineteenth and twentieth centuries, created by Dr Michael Kerney (1934–2022), an acknowledged authority on the subject.

The database made of 45 tables and organised by source of citation is a comprehensive index of mentions that include descriptions of stain glass windows from texts published in Victorian period up until late 20th century. Michael wanted to document the stain glass making and production of the Victorian period and he recorded the mentions that described new additions to church buildings in England (for example, a new stain glass window added or replaced during restoration work). His work however extended to cover the stain glass making and production of the 20th century. Such indexed citations came from variety of sources, including published, rare primary sources and archive material. The most unique and valuable table is the SLIDES & NOTES as it contains descriptions to colour photographic slides collection of over 7000 images of stain-glass windows created by Michael himself during his survey visits to churches across England.

The database was created with Paradox system and stored locally on a personal laptop IBM ThinkPad R40e, a model released by IBM in October 2003 and discontinued year after in October 2004. The database has never had a front-end. Access to data was provided by paper print outs sent by Michael by post. Although archival science dictates that we should always preserve the records in the way they were used this approach will not serve well our current archive community. We are now considering different ways of preserving the datasets. The poster presents work in progress and explains how the data was migrated and extracted from the original Paradox system.

description: We introduce a new type of gamma-ray spectral feature, which we denominate gamma-ray triangle. This spectral feature arises in scenarios where dark matter self-annihilates via a chiral interaction into two Dirac fermions, which subsequently decay in flight into another fermion and a photon. The resulting photon spectrum resembles a sharp triangle and can be readily searched for in the gamma-ray sky. Using data from the Fermi-LAT and H.E.S.S. instruments, we find no evidence for such spectral feature and therefore set strong upper bounds on the corresponding annihilation cross section. A concrete realization of a scenario yielding gamma-ray triangles consists of an asymmetric dark matter model where the dark matter particle carries lepton number. We show explicitly that this class of models can lead to intense gamma-ray spectral features, potentially at the reach of upcoming gamma-ray telescopes, opening a new window to explore asymmetric dark matter through indirect searches.

description: Gastric cancer was and has been a major issue regarding surgical oncology, because even in our days, there are difficulties as well as in the diagnosis, as in its treatment. This thesis refers to a specific subtype of gastric cancer, the Early Gastric Cancer, its definition and epidemiology. Continuing, the differences and specialities of this cancer are described, as well as how it is staged and the methods we have to diagnose this specific cancer. Furthermore, we analyze how this cancer is treated (endoscopically-surgically) and the differences in its treatment methods in Japan-S. Korea and the other world. In conclusion, the importance of screening protocols and early diagnosis is depicted, because of how it affects the long-term survival and the quality of life of the patient.
DEVLOPING STRUCTURE-PROPERTY RELATIONSHIPS IN RADICAL POLYMERS THROUGH ADVANCED MACROMOELCULAR DESIGN

description: Recently, there has been significant increase in research and development in the field of organic electronics. This is mainly because organic electronic devices can be flexible, lightweight, and processed from solution using low-cost manufacturing techniques. Typically, these devices have utilized conjugated polymers as their active layer components. This approach has been successful, but the use of conjugated polymers comes with limitations. To address these limitations and expand the field of organic electronics, this work studies a novel class of macromolecules, radical polymers. Unlike their conjugated polymer counterparts, radical polymers are comprised of a non-conjugated backbone with stable open-shell groups at their pendant sites. By studying the structure-property relationships of these radical polymers, this work developed novel polymer systems for a variety of organic electronic applications. Furthermore, these studies can be applied to future radical polymer systems yet to be discovered. Ultimately, this work served as a template for expanding the field of organic electronics.

description: We obtain a closed system of equations for scalar perturbations in a multi-component braneworld. Our braneworld possesses a phantom-like equation of state at late times, $w_{\rm eff} < -1$, but no big-rip future singularity. In addition to matter and radiation, the braneworld possesses a new effective degree of freedom - the 'Weyl fluid' or 'dark radiation'. Setting initial conditions on super-Hubble spatial scales at the epoch of radiation domination, we evolve perturbations of radiation, pressureless matter and the Weyl fluid until the present epoch. We observe a gradual decrease in the amplitude of the Weyl-fluid perturbations after Hubble-radius crossing, which results in a negligible effect of the Weyl fluid on the evolution of matter perturbations on spatial scales relevant for structure formation. Consequently, the quasi-static approximation of Koyama and Maartens provides a good fit to the exact results during the matter-dominated epoch. We find that the late-time growth of density perturbations on the brane proceeds at a faster rate than in $Λ$CDM. Additionally, the gravitational potentials $Φ$ and $Ψ$ evolve differently on the brane than in $Λ$CDM, for which $Φ= Ψ$. On the brane, by contrast, the ratio $Φ/Ψ$ exceeds unity during the late matter-dominated epoch ($z \lesssim 50$). These features emerge as "smoking gun" tests of phantom brane cosmology and allow predictions of this scenario to be tested against observations of galaxy clustering and large-scale structure.

description: We compare the diversity of spectral line velocities in a large sample of type IIb supernovae (SNe IIb) with the expected asphericity in the explosion, as measured from the light echoes of Cassiopeia A (Cas A), which was a historical galactic SN IIb. We revisit the results of Rest et al. (2011a), who used light echoes to observe Cas A from multiple lines of sight and hence determine its asphericity, as seen in the velocity of three spectral lines (He I $λ$5876, H$α$ and the Ca II NIR triplet). We confirm and improve on this measurement by reproducing the effect of the light echoes in the spectra of several extragalactic SNe IIb found in the literature as well as mean SN IIb spectra recently created by Liu et al. (2016), and comparing these to the observed light echo spectra of Cas A, including their associated uncertainties. In order to quantify the accuracy of this comparison we smooth the light echo spectra of Cas A using Gaussian processes and use a Monte Carlo method to measure the absorption velocities of these three features in the spectra. We then test the hypothesis that the diversity of ejecta velocities seen in SNe IIb can be explained by asphericity. We do this by comparing the range of velocities seen in the different light echoes, and hence different lines of sight, of Cas A to that seen in the population of SNe IIb. We conclude that these two ranges are of the same order and thus asphericity could be enough to explain the diversity in the expansion velocity alone.

description: A fund model is presented for several contract subtypes involving stable value protection on 401K tax-sheltered investment plans. The model does not perform pricing, but rather makes an estimate of expected losses. The estimation of fees received in compensation for extending the value protection is not treated in the model, although the loss estimation appears to be consistent with the detailed structure of these contracts.

On the lamppost model of accreting black holes

description: We study the lamppost model, in which the X-ray source in accreting black-hole systems is located on the rotation axis close to the horizon. We point out a number of inconsistencies in the widely used lamppost model relxilllp, e.g., the neglect of the redshift of the photons emitted by the lamppost and directly observed. They appear to invalidate those model fitting results for which the source distances from the horizon are within several gravitational radii. Furthermore, if those results were correct, most of the photons produced in the lamppost would be trapped by the black hole, and the luminosity generated in the source as measured at infinity would be much larger than that observed. This appears to be in conflict with the observed smooth state transitions between the hard and soft states of X-ray binaries. The required increase of the accretion rate and the associated efficiency reduction present also a problem for AGNs. Then, those models imply the luminosity measured in the local frame to be much higher than that produced in the source and measured at infinity, due to the additional effects of time dilation and redshift, and the electron temperature to be higher significantly than that observed. We show that these conditions imply that the fitted sources would be out of the pair equilibrium. On the other hand, the above issues pose relatively minor problems for sources at large distances from the black hole, where relxilllp can still be used.

description: We investigate the dynamics of solar activity using a nonlinear one-dimensional dynamo model and a phenomenological equation for the evolution of Wolf numbers. This system of equations is solved numerically. We take into account the algebraic and dynamic nonlinearities of the alpha effect. The dynamic nonlinearity is related to the evolution of a small-scale magnetic helicity, and it leads to a complicated behavior of solar activity. The evolution equation for the Wolf number is based on a mechanism of formation of magnetic spots as a result of the negative effective magnetic pressure instability (NEMPI). This phenomenon was predicted 25 years ago and has been investigated intensively in recent years through direct numerical simulations and mean-field simulations. The evolution equation for the Wolf number includes the production and decay of sunspots. Comparison between the results of numerical simulations and observational data of Wolf numbers shows a 70 % correlation over all intervals of observation (about 270 years). We determine the dependence of the maximum value of the Wolf number versus the period of the cycle and the asymmetry of the solar cycles versus the amplitude of the cycle. These dependencies are in good agreement with observations.

description: Developing objective methods for assessing the severity of Parkinson's disease (PD) is crucial for improving the diagnosis and treatment. This study proposes two sets of novel features derived from the single frequency filtering (SFF) method: (1) SFF cepstral coefficients (SFFCC) and (2) MFCCs from the SFF (MFCC-SFF) for the severity classification of PD. Prior studies have demonstrated that SFF offers greater spectro-temporal resolution compared to the short-time Fourier transform. The study uses the PC-GITA database, which includes speech of PD patients and healthy controls produced in three speaking tasks (vowels, sentences, text reading). Experiments using the SVM classifier revealed that the proposed features outperformed the conventional MFCCs in all three speaking tasks. The proposed SFFCC and MFCC-SFF features gave a relative improvement of 5.8% and 2.3% for the vowel task, 7.0% & 1.8% for the sentence task, and 2.4% and 1.1% for the read text task, in comparison to MFCC features.
