description: The main aim of the present paper is to establish the existence of a phase transition for the quantum Ising model with competing XY interactions within the quantum Markov chain (QMC) scheme. In this scheme, we employ the $C^*$-algebraic approach to the phase transition problem. Note that these kinde of models do not have one-dimensional analogues, i.e. the considered model persists only on trees. It turns out that if the Ising part interactions vanish then the model with only competing XY -interactions on the Cayley tree of order two does not have a phase transition. By phase transition we mean the existence of two distinct QMC which are not quasi-equivalent and their supports do not overlap. Moreover, it is also shown that the QMC associated with the model have clustering property which implies that the von Neumann algebras corresponding to the states are factors.

description: Qatar is one of the most developed countries worldwide that became an ideal destination for residence, thereby leading to an increase in the population. This resulted in a consequent increase in solid waste generation in the country, which is bound to overload the waste management system. The present thesis proposes certain models and approaches for selecting the location of Qatar’s waste transfer stations using different optimization tools. A mathematical model was developed to describe four different configurations that attempt to optimize the current and future system of waste management: (i) the addition of new permanent waste transfer facilities that accept multiple types of waste; (ii) the addition of new temporary waste transfer stations facilities that accept one type of waste; (iii) the selection of new permanent waste transfer stations regardless of whether it is an existing or potential site and it is capable of handling multiple types of waste; and (iv) the selection of new permanent waste transfer stations that will be capable of handling multiple types of waste and temporary waste transfer stations that will handle one type of waste, regardless whether they are an existing or potential site. Among the considered configurations, the results showed that configuration model 4 works the best. It selects three out of five existing waste transfer stations, three potential permanent sites, and four temporary waste transfer stations at the minimum overall cost compared to the outcomes provided by the other three models. The validity of the results of the model was confirmed even by the analytical hierarchy process (AHP) method, which provided results that match the mathematical model’s outcomes up to 90%. The novelty of the proposed models includes utilizing multiple optimization tools for selecting the locations of solid waste transfer stations in Qatar and introducing the employment of temporary transfer stations for the first time.

description: In conventional OCT, broadband light sources are generally utilized to obtain high axial resolution due to their low temporal coherence (TC) length. Purely monochromatic (i.e., high TC length) light sources like laser cannot be implemented to acquire high resolution optically sectioned images of the specimen. Contrary to this, pseudo thermal light source having high TC and low spatial coherence (SC) property can be employed to achieve high axial resolution comparable to broadband light source. In the present letter, a pseudo thermal light source is synthesized by passing a purely monochromatic laser beam through a rotating diffuser. The longitudinal coherence (LC) property of the pseudo thermal light source is studied as a function of source size and TC length. The LC length of the synthesized light source decreased as the source size increased. It is found that LC length of such light source becomes independent of the parent laser TC length for source size of greater than or equal to 3.3 mm and become almost constant at around 30 micron for both the lasers. Thus any monochromatic laser light source can be utilized to obtain high axial resolution in OCT system irrespective of its TC length. The maximum achievable axial resolution is found to be equal to 650 nm corresponding to 1.2 numerical aperture (NA) objective lens at 632 nm wavelength. The findings elucidate that pseudo thermal source being monochromatic in nature can improve the performance of existing OCT systems significantly.

description: Blending Game localisation modifies the various channels of information in video games to suit the target culture norms. Game localisation is part of audiovisual translation where localisers translate, adapt, and manipulate game content from the source language into the target language. Game developers consider the localisation process necessary to be able to publish their games in foreign markets. This study examines the localisation of religious and obscene references in FiestaOnline among the linguistic, visual, and interactive layers by comparing it to Arafiesta, the Arabic localised version of the game. A total of 740 dialogue strings, which included religious and obscene linguistic elements, were collected, in addition to capturing several screenshots and video footages to compare visual and interactive features. A unique framework was schemed after combining three existent frameworks in order to analyse the data. Also, a list of questions was sent to the localisation company which they responded to via email. The research results show that localisers tend to utilise semantic misrepresentation among both types of references as the most frequent technique. Visual features have been generally retained, but the covering method has been commonly used among character appearances while interactive aspects fluctuate among retaining, deletion, and manipulation. Finally, the thesis concludes that blending game localisation can be implemented on game imports into the Arab world as the gaming market is generally increasing in the Middle-East and North Africa (MENA) region.

description: The Great American Biotic Interchange is considered to be a punctuated process, occurring during four major pulses that began approximately 2.5 Ma. Central America and southeastern Mexico have a poor fossil record of this dynamic faunal history due to tropical climates. Exploration of submerged caves in the Yucatán, particularly the natural trap Hoyo Negro, is exposing a rich and remarkably well-preserved late Pleistocene fauna. Extinct megafauna from the site date approximately 38 400–12 850 cal BP includes the ursid Arctotherium wingei and canid Protocyon troglodytes. Both genera were previously thought to be indigenous to and confined to South America and appear to represent an instance of large placental mammals, descended from North American progenitors, migrating back north across the Panama Isthmus. This discovery expands the distribution of these carnivorans greater than 2000 km outside South America. Their presence along with a diverse sloth assemblage suggests a more complex history of these organisms in Middle America. We suggest that landscape and ecological changes caused by latest Pleistocene glaciation supported an interchange pulse that included A. wingei, P. troglodytes and Homo sapiens.

description: We consider a string-inspired, gravitational theory of scalar and electromagnetic fields and we investigate the existence of axially-symmetric, Gödel-type cosmological solutions. The neutral case is studied first and an "extreme" Gödel-type rotating solution, that respects the causality, is determined. The charged case is considered next and two new configurations for the, minimally-coupled to gravity, electromagnetic field are presented. Another configuration motivated by the expected distribution of currents and charges in a rotating universe is studied and shown to lead to a Gödel-type solution for a space-dependent coupling function. Finally, we investigate the existence of Gödel-type cosmological solutions in the framework of the one-loop corrected superstring effective action and we determine the sole configuration of the electromagnetic field that leads to such a solution. It turns out that, in all the charged cases considered, Closed Timelike Curves do appear and the causality is always violated.

description: Firm relocation can be viewed as an entrepreneurial strategy of the firm to remove real or imagined limits to growth and, as such, the migration of a firm from a region can represent the loss of a current and potentially growing employer. We consider an extended resource based theory of the firm to explain the propensity to relocate. By analyzing the interviews of the chief executive officers of companies in the agro-food sector, we show that the internal resources of the firm, its degree of globalization, and its territorial embeddedness represent important factors determining the relocation decision.

description: Tensor Robust Principal Component Analysis (TRPCA) is a procedure for recovering a data structure that has been corrupted by noise. In this thesis, a proof (inspired by Lu et al. (2018)) is given that TRPCA successfully performs this operation. An online optimisation algorithm to perform this procedure for p-dimensional tensors is proposed (based on a similar algorithm for the 3-dimensional case from Z. Zhang, Liu, Aeron, & Vetro (2016)). The required tensor identities to apply a proof of convergence (similar to the approach of Feng, Xu, & Yan (2013) for the matrix case) are derived and then applied. Examples using satellite image data and synthetic data are provided throughout to demonstrate the utility of the theoretical work and examine hypotheses.

description: Recursive optimization strategies for Large Language Models (LLMs) introduce additional complexity into gradient-based learning processes, particularly when weight updates depend on prior optimization states. The introduction of self-referential gradient propagation presents an alternative mechanism where LLM parameters are adjusted based on internal evaluations of past gradient trajectories, modifying conventional optimization pathways through an adaptive recursive feedback loop. A structured evaluation of the method compared training dynamics, computational efficiency, and stability characteristics against conventional backpropagation-based training methodologies. Experimental results indicated that self-referential updates contributed to more stable weight adjustments, reducing abrupt fluctuations in gradient magnitudes while maintaining competitive performance across a range of tasks. The impact of recursive gradient storage on memory consumption was analyzed, highlighting the trade-off between additional computational overhead and potential improvements in optimization smoothness. The sensitivity of self-referential updates to hyperparameter variations was assessed, revealing that LLMs trained with recursive optimization exhibited reduced volatility in loss trajectories compared to conventional approaches. An evaluation of robustness under noisy input conditions demonstrated that LLMs trained with recursive adjustments retained greater accuracy when exposed to corrupted inputs. The findings suggested that self-referential optimization introduced an alternative framework for gradient-based learning, modifying parameter updates through internally computed adjustments rather than externally applied heuristic scheduling.

description: For named entity recognition (NER), bidirectional recurrent neural networks became the state-of-the-art technology in recent years. Competing approaches vary with respect to pre-trained word embeddings as well as models for character embeddings to represent sequence information most effectively. For NER in German language texts, these model variations have not been studied extensively. We evaluate the performance of different word and character embeddings on two standard German datasets and with a special focus on out-of-vocabulary words. With F-Scores above 82% for the GermEval'14 dataset and above 85% for the CoNLL'03 dataset, we achieve (near) state-of-the-art performance for this task. We publish several pre-trained models wrapped into a micro-service based on Docker to allow for easy integration of German NER into other applications via a JSON API.

description: Biosorption has been shown in the literature to be effective in the removal of dye from aqueous solution. To be fully useful, a desorption process is necessary, which has a direct impact on the process costs. The aim of this work was to evaluate the desorption of the azo dye Acid Yellow 23 adsorbed in a biosorbent obtained from Bombyx mori cocoons. Temperature and pH media were evaluated through a mixed two- and three-level design, using NaOH as desorbing agent. Kinetic desorption was also obtained at the optimized condition. The statistical evaluation of the experimental design showed that the pH has almost two times more influence on the dye desorption than the temperature, with only the linear parameters being statistically significant. Among four kinetic desorption models adjusted to the experimental data, the proposed n-order model was statistically determined as the best representation of the experimental data.

description: Harmonic maps from S^2 to S^2 are all weakly conformal, and so are represented by rational maps. This paper presents a study of the L^2 metric gamma on M_n, the space of degree n harmonic maps S^2 -> S^2, or equivalently, the space of rational maps of degree n. It is proved that gamma is Kaehler with respect to a certain natural complex structure on M_n. The case n=1 is considered in detail: explicit formulae for gamma and its holomorphic sectional, Ricci and scalar curvatures are obtained, it is shown that the space has finite volume and diameter and codimension 2 boundary at infinity, and a certain class of Hamiltonian flows on M_1 is analyzed. It is proved that \tilde{M}_n, the space of absolute degree n (an odd positive integer) harmonic maps RP^2 -> RP^2, is a totally geodesic Lagrangian submanifold of M_n, and that for all n>1, \tilde{M}_n is geodesically incomplete. Possible generalizations and the relevance of these results to theoretical physics are briefly discussed.

description: Chronic Myeloid Leukemia (CML) is a hematological malignancy caused by translocation between chromosome 9 and 22 t(9;22) named as Philadelphia (Ph) chromosome through BCR-ABL1oncoprotein. CML exhibit high sensitivity toward targeted therapy, genomic abnormalities and immune editing. The gold standard treatment for CML is Tyrosine Kinase inhibitor (TKI) targeting BCR-ABL1. TKI is a life-long treatment that required routine monitoring protocol. CML patients’ response is monitored by molecular quantification of BCR-ABL1 mRNA using RT-qPCR techniques, reported in the International Scale (IS) reporting system, and classified into: optimal, warning, and failure. In this thesis, we report on karyotyping of CML patients at diagnosis and present data on quantification of cytokines, chemokines, and soluble immune checkpoint inhibitors in 5 optimal and 6 warning CML patients after at least 6 months of TKI administration. We further investigated the long-term inhibitory effect of Additional Chromosome Abnormalities (ACA) on the immune system in shaping the patients’ response to TKI. Our results showed a deferential immune profile in the warning group indicated by 1) downregulation in cytokines and chemokines required for activation, differentiation, recruitment, maturation of immune effector cells, such as TNF-α, MIP-1α, MIP-1 β, IL-7, IL-1β, IL-4, IL-5, IL-13, IL-17A which may indicate an immune escape mechanism from TKI in this group; 2) upregulation of I-TAC a marker associated with tumor growth. Interestingly, one patient from the warning group (G1-P12) who carries additional chromosomal abnormality associated with poor prognosis, exhibited also upregulation of soluble immune checkpoint inhibitors (MICA/B, CD73, CD96, LAG3, PD-L2, BTLA, CD80) known to be associated with bad prognosis. In conclusion, we have identified a common deferential cytokine/chemokine profile in the warning group that may predict the response of CML patients to TKI treatment.

description: Digital technology and social media have transformed the way we communicate. The advent of the Covid-19 pandemic has further quadrupled the use of social media platforms especially Twitter to share opinions, sentiments, and garner information. The situation surrounding the Covid-19 pandemic is rapidly evolving ranging from preventive measures taken by health authorities, government policies, and negative psychological reactions like fear and so on. Accordingly, real-time monitoring and assessment of Twitter discussions and concerns could provide useful data for public health emergency responses and planning. Vaccine-related concerns and sentiments may influence public trust in the vaccines and subsequently lead to vaccine hesitance (Xue, 2020).There is a lot of disinformation and conspiracies surrounding the Covid-19 vaccines. The theories about vaccines having microchips in them, depopulation, the vaccine causing the new mutant virus, causing infertility or zombifying people appear to surround the vaccines. Through word frequency, sentiment, and topic modeling analysis this paper sought to understand the response of the public toward the Covid-19 vaccines. The examination of tweets found that female Twitter users have a slightly more positive sentiments and emotions towards the vaccines compared to males. Both males and females used various hashtags in support or opposition to the vaccine, and on average, males used more anti-vaccine hashtags than females. Topic modeling through unsupervised machine learning showed that both males and females talked about similar topics but differed in the degree of frequency and perspectives.

We calculate the exact ground state wave functional of the model for any bilocal potential, and also study its long-distance behavior. We show that the ground state wave functional has a general factored Jastrow form. We also find that it posess an interesting symmetry involving the interchange of density-density and current-current interactions.

(2021) velocity decomposition algorithm (VDA) for separating such fluctuations in the position-position-velocity (PPV) space. In the first version of this manuscript they came to the conclusion that velocity and density fields are statistically correlated. Yuen et al. (2021) tried to reproduce these results and pointed to a likely mistake in the VDA expression that was used. We confirm that there was such a software problem. The statement that VDA derived density and velocity fields from HI4PI are anti-correlated needs to be withdrawn. Correct is that these density and velocity fields are uncorrelated. In turn major parts of the conclusions in the first version of this manuscript, based on an erroneous correlation, are invalid. The submission to A&A was withdrawn on 24 February 2022.

description: Asymmetric debris discs have been found around stars other than the Sun; asymmetries are sometimes attributed to perturbations induced by unseen planets. The presence or absence of asymmetries in our own trans-Neptunian belt remains controversial. The study of sensitive tracers in a sample of objects relatively free from the perturbations exerted by the four known giant planets and most stellar flybys may put an end to this debate. The analysis of the distribution of the mutual nodal distances of the known extreme trans-Neptunian objects (ETNOs) that measure how close two orbits may get to each other could be such a game changer. Here, we use a sample of 51 ETNOs together with random shufflings of this sample and two unbiased scattered-disc orbital models to confirm a statistically significant (62 sigma) asymmetry between the shortest mutual ascending and descending nodal distances as well as the existence of multiple highly improbably (p < 0.0002) correlated pairs of orbits with mutual nodal distances as low as 0.2 au at 152 au from the Solar system's barycentre or 1.3 au at 339 au. We conclude that these findings fit best with the notion that trans-Plutonian planets exist.

description: It is known that traversible wormholes require negative energy density. We here argue how much negative energy is needed for wormholes, using a local analysis which does not assume any symmetry. and in particular allows dynamic (non-stationary) but non-degenerate wormholes. We find that wormholes require two constraints on the energy density, given by two independent components of the Einstein equation.

description: Using Roelcke formula for the Green function, we explicitly construct a basis in the kernel of the adjoint Laplacian on a compact polyhedral surface $X$ and compute the $S$-matrix of $X$ at the zero value of the spectral parameter. We apply these results to study various self-adjoint extensions of a symmetric Laplacian on a compact polyhedral surface of genus two with a single conical point. It turns out that the behaviour of the $S$-matrix at the zero value of the spectral parameter is sensitive to the geometry of the polyhedron.

description: Emotional styles, which compose an individual’s dependable pattern of responses to their temporary emotional states, have been associated with academic success, life satisfaction, and flourishing mental health, but have not been studied in terms of work-related burnout. Navigating emotions is essential across many occupational settings, which makes emotional styles relevant to work and burnout. The current study examines the relationship between emotional styles and burnout among clergy and explores whether emotional styles might moderate the relationship between burnout and length of time in ministry. Drawing from the Clergy Health Initiative Longitudinal Survey, we used the Emotional Styles Questionnaire and the three components of the Maslach Burnout Inventory in multiple regression analyses and found that five emotional styles (Outlook, Resilience, Self-awareness, Sensitivity to Context, Attention) were significantly associated with each burnout outcome. Moderation analyses showed that higher emotional style scores were associated with better burnout scores for participants with more years of ministry experience. These findings provide the groundwork for future longitudinal studies to determine whether change in emotional styles can improve burnout, especially mid-career.

Jamming by growth

description: Growth in confined spaces can drive cellular populations through a jamming transition from a fluid-like state to a solid-like state. Experiments have found that jammed budding yeast populations can build up extreme compressive pressures (over 1MPa), which in turn feed back onto cellular physiology by slowing or even stalling cell growth. Using extensive numerical simulations, we investigate how this feedback impacts the mechanical properties of model jammed cellular populations. We find that feedback directs growth toward poorly-coordinated regions, resulting in an excess number of cell-cell contacts that rigidify cell packings. Cell packings posses anomalously large shear and bulk moduli that depend sensitively on the strength of feedback. These results demonstrate that mechanical feedback on the single-cell level is a simple mechanism by which living systems can tune their population-level mechanical properties.

Optical creation of vibrational intrinsic localized modes in anharmonic lattices with realistic interatomic potentials

description: Using an efficient optimal control scheme to determine the exciting fields, we theoretically demonstrate the optical creation of vibrational intrinsic localized modes (ILMs) in anharmonic perfect lattices with realistic interatomic potentials. For systems with finite size, we show that ILMs can be excited directly by applying a sequence of femtosecond visible laser pulses at THz repetition rates. For periodic lattices, ILMs can be created indirectly via decay of an unstable extended lattice mode which is excited optically either by a sequence of pulses as described above or by a single picosecond far-infrared laser pulse with linearly chirped frequency. In light of recent advances in experimental laser pulse shaping capabilities, the approach is experimentally promising.

description: The robust generation and manipulation of entangled multiphoton states on-chip has an essential role in quantum computation and communication. Lattice topology has emerged as a means of protecting photonic states from disorder but entanglement across different topologies remained unexplored. We report biphoton entanglement between topologically distinct spatial modes in a bipartite array of silicon waveguides. The results highlight topology as an additional degree of freedom for entanglement and open avenues for investigating information teleportation between trivial and topological modes.

description: Analytically calculating high-order origin moments of a negative binomial distribution has long been a persistent and challenging problem. In this study, we employ an expectation identity method to analytically compute these moments. First, we restate the expectation identity theorem for the negative binomial distribution. Subsequently, using this method, we derive analytical expressions for the first four origin moments as well as the general kth (k=1,2,…) moment of the negative binomial distribution. Finally, we present a table displaying polynomial coefficients for the first 10 origin moments and highlight that their leading coefficients correspond to Stirling numbers of the second kind.
