description: BackgroundDirect access to diagnostic imaging in General Practice provides an avenue to reduce refer?rals to hospital-based specialities and emergency departments, and to ensure timely diagnosis. Enhanced GP access to radiology imaging could potentially reduce hospital referrals, hospital admissions, enhance patient care, and improve disease outcomes. This scoping review aims to demonstrate the value of direct access to diagnostic imaging in General Practice and how it has impacted on healthcare delivery and patient care.MethodsA search was conducted of ‘PubMed’, ‘Cochrane Library’, ‘Embase’ and ‘Google Scholar’ for papers published between 2012–2022 using Arksey and O’Malley’s scoping review framework. The search process was guided by the PRISMA extension for Scoping Reviews checklist (PRISMA-ScR).ResultsTwenty-three papers were included. The studies spanned numerous geographical locations (most commonly UK, Denmark, and Netherlands), encompassing several study designs (most commonly cohort studies, randomised controlled trials and observational studies), and a range of populations and sample sizes. Key outcomes reported included the level of access to imaging serves, the feasibility and cost effectiveness of direct access interventions, GP and patient satisfaction with direct access initiatives, and intervention related scan waiting times and referral process.ConclusionDirect access to imaging for GPs can have many benefits for healthcare service delivery, patient care, and the wider healthcare ecosystem. GP focused direct access initiatives should therefore be considered as a desirable and viable health policy directive. Further research is needed to more closely examine the impacts that access to imaging studies have on health system operations, especially those in General Practice. Research examin?ing the impacts of access to multiple imaging modalities is also warranted.

description: The purpose of The Invisi-Bump project is to address the inconvenience caused by
traditional speed bumps. This method of traffic control causes damage to vehicles, increases levels
of pollution, causes traffic jams, and is a nuisance to drivers whether they choose to slow down or
not. The Invisi-Bump is a smart speed bump capable of detecting the speed of an oncoming vehicle
and reacting based on that speed. A vehicle traveling at or below the speed limit will experience
no interruption while a speeding vehicle will experience a bump. The key features of the design
include a speed sensing device, image recognition system for detecting emergency vehicles, a
linear actuator and a robust system of linkages for raising the bump surface. A four-foot long bump
was created and tested as a proof-of-concept prototype. The Invisi-Bump can result in safer roads,
less pollution, and smoother driving experiences.

description: The Jiangmen Underground Neutrino Observatory (JUNO), is a 20 kton multi-purpose liquid-scintillator detector to be completed in 2023. Its main goal is the determination of the neutrino mass ordering using the measurement of the vacuum-dominated oscillation pattern of reactor anti-neutrinos from two nearby nuclear power plants. The sensitivity of JUNO to the neutrino mass ordering can be enhanced via a combined analysis of reactor anti-neutrinos with atmospheric neutrinos, in which the matter-dominated oscillation depends on the mass ordering. Such an analysis requires a precise reconstruction of the energy and the direction of atmospheric neutrinos. As the largest liquid-scintillator detector to be built, JUNO will also be able to measure the atmospheric neutrino flux down to lower energies than the current large water/ice Cherenkov detectors. This poster presents the reconstruction of the energy of atmospheric neutrinos with a machine learning approach and the direction reconstruction with a traditional approach. Both approaches are a Monte Carlo based study, the latter focuses on the reconstruction of the photon emission topology in the JUNO detector, while the machine learning approach relies on the geometrical representation of the detector with a Graph Convolutional Neural Network.

description: We theoretically study electro-optic light modulation based on the quantum model where the linear electro-optic effect and the externally applied microwave field result in the interaction between optical cavity modes. The model assumes that the number of interacting modes is finite and effects of the mode overlapping coefficient on the strength of the intermode interaction can be taken into account through dependence of the coupling coefficient on the mode characteristics. We show that, under certain conditions, the model is exactly solvable and, in the semiclassical approximation where the microwave field is treated as a classical mode, can be analyzed using the technique of the Jordan mappings for the su(2) Lie algebra. Analytical results are applied to study effects of light modulation on the frequency dependence of the photon counting rate. We also establish the conditions of validity of the semiclassical approximation by applying the methods of polynomially deformed Lie algebras for analysis of the model with quantized microwave field.

description: En el presente artículo se analizó la organización espacial de las áreas de almacenamiento en los palacios Uhle y Bandelier de Chan Chan (Perú) para comprender las implicancias administrativas del estado Chimú (siglos IX-XV). Su objetivo fue identificar cómo la distribución arquitectónica reflejaba el control político y económico, utilizando el software AGRAPH para aplicar sintaxis espacial. El paradigma fue cuantitativo ya que estudia las relaciones sociales a través de las tendencias espaciales. La metodología incluyó el análisis de índices sintácticos (control valor, integración, relatividad asimétrica, distancia media y distancia total) sobre planos arqueológicos previamente documentados, sin muestreo tradicional, ya que se trabajó con la totalidad de las estructuras conservadas en ambos palacios. Los resultados revelaron diferencias clave: en Uhle, los patios y audiencias controlaban rigurosamente el acceso a los depósitos, mientras que en Bandelier existían sectores aislados, sugiriendo estrategias administrativas distintas. El estudio corrobora arqueológicamente la relación entre audiencias (estructuras en "U") y almacenamiento, validando hipótesis previa propuesta por Moore,  y aportando evidencia sobre el perfeccionamiento de sistemas burocráticos Chimú. La técnica permitió inferir jerarquías sociales y uso ceremonial de los espacios, aunque persisten limitaciones por la ausencia de artefactos en Bandelier.
description: This paper analyzed the spatial organization of storage areas in the Uhle and Bandelier palaces at Chan Chan (Peru) to understand the administrative implications of the Chimú state (9th-15th centuries). Its objective was to identify how architectural distribution reflected political and economic control, using AGRAPH software to apply spatial syntax. The paradigm was quantitative as it studies social relations through spatial trends. The methodology included the analysis of syntactic indices (value control, integration, asymmetric relativity, average distance and total distance) on previously documented archaeological plans, without traditional sampling, since we worked with the totality of the structures preserved in both palaces. The results revealed key differences: in Uhle, the courtyards and audiences strictly controlled access to the deposits, while in Bandelier there were isolated sectors, suggesting different administrative strategies. The study archaeologically corroborates the relationship between audiencias (U-shaped structures) and storage, validating previous hypotheses proposed by Moore, and providing evidence on the refinement of Chimú bureaucratic systems. The technique allowed inferring social hierarchies and ceremonial use of the spaces, although limitations persist due to the absence of artifacts in Bandelier.

description: We studied the environment of the dust bubble N10 in molecular emission. Infrared bubbles, first detected by the GLIMPSE survey at 8.0 $μ$m, are ideal regions to investigate the effect of the expansion of the HII region on its surroundings eventual triggered star formation at its borders. In this work, we present a multi-wavelength study of N10. This bubble is especially interesting as infrared studies of the young stellar content suggest a scenario of ongoing star formation, possibly triggered, on the edge of the HII region. We carried out observations of $^{12}$CO(1-0) and $^{13}$CO(1-0) emission at PMO 13.7-m towards N10. We also analyzed the IR and sub-mm emission on this region and compare those different tracers to obtain a detailed view of the interaction between the expanding HII region and the molecular gas. We also estimated the parameters of the denser cold dust condensation and of the ionized gas inside the shell. Bright CO emission was detected and two molecular clumps were identified, from which we have derived physical parameters. We also estimate the parameters for the densest cold dust condensation and for the ionized gas inside the shell. The comparison between the dynamical age of this region and the fragmentation time scale favors the "Radiation-Driven Implosion" mechanism of star formation. N10 reveals to be specially interesting case with gas structures in a narrow frontier between HII region and surrounding molecular material, and with a range of ages of YSOs situated in region indicating triggered star formation.

description: In this paper, we develop a numerical resolution of the space-time fractional advection-dispersion equation. After time discretization, we utilize collocation technique and implement a product integration method in order to simplify the evaluation of the terms involving spatial fractional order derivatives. Then utilizing Bernstein polynomials as basis, the problem is transformed into a linear system of algebraic equations. Error analysis and order of convergence for the proposed method are also discussed. Some numerical experiments are presented to demonstrate the effectiveness of the proposed method and to confirm the analytic results.

description: We model the possible afterglow of the Fermi GBM event associated with LIGO detection GW150914, under the assumption that the gamma-ray are produced by a short GRB-like relativistic outflow. We model GW150914-GBM as both a weak, on-axis short GRB and normal short GRB seen far off axis. Given the large uncertainty in the position of GW150914, we determine that the best chance of finding the afterglow is with ASKAP or possibly the MWA, with the flux from an off-axis short GRB reaching 0.2 - 4 mJy (0.12 - 16 mJy) at 150 MHz (863.5 MHz) by 1 - 12 months after the initial event. At low frequencies, the source would evolve from a hard to soft spectrum over several months. The radio afterglow would be detectable for several months to years after it peaks, meaning the afterglow may still be detectable and increasing in brightness NOW (mid-July 2016). With a localization from the MWA or ASKAP, the afterglow would be detectable at higher radio frequencies with the ATCA and in X-rays with Chandra or XMM.

description: The magnetic and nematic properties of the iron chalcogenides have recently been the subject of intense interest. Motivated by the proposed antiferroquadrupolar and Ising-nematic orders for the bulk FeSe, we study the phase diagram of an $S=1$ generalized bilinear-biquadratic model with multi-neighbor interactions. We find a large parameter regime for a ($π$,0) antiferroquadrupolar phase, showing how quantum fluctuations stabilize it by lifting an infinite degeneracy of certain semiclassical states. Evidence for this C$_4$-symmetry-breaking quadrupolar phase is also provided by an unbiased density matrix renormalization group analysis. We discuss the implications of our results for FeSe and related iron-based superconductors.

description: Medulloblastoma (MB) is the most common form of paediatric brain tumour, representing 20 % of all paediatric intercranial tumours. Aggressive treatment protocols generally consisting of chemotherapy, radiation therapy and surgery are deployed to treat MB, yielding a 5-year overall survival rate of ~ 70 % for patients with average risk disease. However, radiation therapy is associated with high levels of toxicity and significant adverse effects, and long-term sequelae can be severe. The use of genotoxic chemotherapy is of particular relevance for subsets of patients who have limited therapeutic options, and here a personalised approach to therapeutic decision-making would facilitate the stratification of patients and identify those likely to respond to chemotherapy, so that they could be spared unnecessary treatments and associated toxicities. Therefore, there is a need to identify molecular patterns that can reliably predict therapeutic responsiveness. Here, we have analysed the expression levels of 14 proteins involved in apoptosis signalling, both upstream and downstream of mitochondrial outer membrane permeabilization in MB cell lines, and found that a Principal Component Analysis approach could be used to identify the chemotherapeutic responsiveness of individual cell lines. When applied to patient mRNA data, we observed that this approach identified that a significant proportion of these patients were predicted to have chemosensitive disease, highlighting the potential that approaches such as these could have in stratifying patients for personalised treatment, and sparing them the toxicities associated with unnecessary treatment. We also sought to determine anti-apoptotic dependencies of these cell lines that could be exploited to potentiate chemotherapy-induced cytotoxicity. Using BH3 profiling, we identified a dependence on the anti-apoptotic protein BCL-XL, and we confirmed that these cells can be sensitised to cisplatin treatment via BCL-XL knockdown, or using the BCL-XL inhibitor WEHI-539. However, WEHI-539 treatment alone does not induce cell death, and we have additionally identified a compensatory role for MCL-1 in protecting cells from WEHI-539 induced cell death. Combined inhibition of BCL-XL and MCL-1 results in extremely rapid induction of caspase-dependent apoptosis, and abolishes clonogenic survival. In summary, our data shows for the first time that quantitative analysis of key apoptosis-related proteins can predict chemosensitivity in medulloblastoma cell lines, and provides rationale for further evaluation of dual inhibition of BCL-XL and MCL-1 in the treatment of medulloblastoma.

description: We obtain box-counting estimates for the pinned distance sets of (dense subsets of) planar discrete Ahlfors-regular sets of exponent $s>1$. As a corollary, we improve upon a recent result of Orponen, by showing that if $A$ is Ahlfors-regular of dimension $s>1$, then almost all pinned distance sets of $A$ have lower box-counting dimension $1$. We also show that if $A,B\subset\mathbb{R}^2$ have Hausdorff dimension $>1$ and $A$ is Ahlfors-regular, then the set of distances between $A$ and $B$ has modified lower box-counting dimension $1$, which taking $B=A$ improves Orponen's result in a different direction, by lowering packing dimension to modified lower box-counting dimension. The proofs involve ergodic-theoretic ideas, relying on the theory of CP-processes and projections.

description: This thesis concentrates on the installation works of multimedia artist Patssi Valdez (born 1951 in East Los Angeles), focusing specifically on the site-specific altar-installations she created between 1990 and 1996. In these large-scale, multimedia works, Valdez employs an artistic technique that follows the tradition of altar-making to construct spaces that extend her meditations on self-fashioning and style beyond the corporeal. Through a myriad of secular, everyday objects as well as sacred Catholic symbols and popular Mexican iconography, Valdez was able to explore alternative avenues of expressing style and cultivating aesthetics. A critical concept in Valdez’s altar-installations is the cosmeticization of space as an artistic practice, or the aesthetic transformation of a physical/material space. Cosmeticization is intrinsically linked to, and emerges from, Valdez’s experience as a professional cosmetologist and from her time as a set and costume designer for Chicano theater and film.

description: Motivated by recent experimental results on glassy polymer nanoparticles, we develop a minimal theoretical framework for the glass transition in spherical confinement. This is accomplished using our cooperative-string model for supercooled dynamics, that was successful at recovering the bulk phenomenology and describing the thin-film anomalies. In particular, we obtain predictions for the mobile-layer thickness as a function of temperature, and for the effective glass-transition temperature as a function of the radius of the spherical nanoparticle - including the existence of a critical particle radius below which vitrification never occurs. Finally, we compare the theoretical results to experimental data on polystyrene from the recent literature, and we discuss the latter.
Implementation of Interior-point Methods for LP based on Krylov Subspace Iterative Solvers with Inner-iteration Preconditioning

description: We apply novel inner-iteration preconditioned Krylov subspace methods to the interior-point algorithm for linear programming (LP). Inner-iteration preconditioners recently proposed by Morikuni and Hayami enable us to overcome the severe ill-conditioning of linear equations solved in the final phase of interior-point iterations. The Krylov subspace methods do not suffer from rank-deficiency and therefore no preprocessing is necessary even if rows of the constraint matrix are not linearly independent. By means of these methods, a new interior-point recurrence is proposed in order to omit one matrix-vector product at each step. Extensive numerical experiments are conducted over diverse instances of 138 LP problems including the Netlib, QAPLIB, Mittelmann and Atomizer Basis Pursuit collections. The largest problem has 434,580 unknowns. It turns out that our implementation is more robust than the standard public domain solvers SeDuMi (Self-Dual Minimization), SDPT3 (Semidefinite Programming Toh-Todd-Tütüncü) and the LSMR iterative solver in PDCO (Primal-Dual Barrier Method for Convex Objectives) without increasing CPU time. The proposed interior-point method based on iterative solvers succeeds in solving a fairly large number of LP instances from benchmark libraries under the standard stopping criteria. The work also presents a fairly extensive benchmark test for several renowned solvers including direct and iterative solvers.

description: Quantum correlations and coherence generated between two free spinless particles in the lattice, interacting with a common quantum phonon bath, are studied. The reduced density matrix is solved using the Markov approach. We show that the bath induces correlations between the particles. The coherence induced by the bath is studied, calculating off-diagonal elements of the density matrix, spatiotemporal dispersion, purity and quantum mutual information. We find a characteristic time-scale pointing out when this coherence is maximum. In addition, a Wigner-like distribution in the phase-space (lattice) is introduced as an indirect indicator of the quantumness of total correlations and coherence induced by the thermal bath. The negative volume of the Wigner function also shows a behavior which is in agreement with the time-scale that we have found. A Gaussian distribution for the profile of particles is not obtained, and interference patterns are observed as the result of bath-induced coherence. As the temperature of the bath vanishes, the ballistic behavior of the tight-binding model is recovered. The geometric quantum discord is calculated, to characterize the nature of the correlations.

description: Respiratory illness due to SARS-CoV-2 emerged in 2019 and has a significant morbidity and mortality rate. The main protease (Mpro) is mainly responsible for viral replications, which acts as a good drug target to inhibit SARS-CoV-2-related diseases. Chemical compounds obtained from various herbal plants are showing potent antiviral activity against numerous viral diseases. Initial screening was performed with the phytochemicals against Mpro using molecular docking. This result shows that there is a strong interaction exhibited between active sites (His-41 and Cys-145) of Mpro with chemical compounds. In addition, ADME prediction and Lipinski’s rule of five (RO5) calculations demonstrated that the selected compounds have potential drug-like properties. Further, molecular dynamics (MD) simulations were performed to understand the stability and structural changes of protein–ligand complexes for the top five compounds. MM/PBSA studies strongly suggested that compounds, β-spinasterol, and asarinin form stable complexes with Mpro. The most significant hot spot residues such as Thr-25, Met-49, Cys-145, Met-165, and Gln-189 have strongly interacted with the selected chemical compounds. Our calculations suggest that asarinin is the best inhibitor to the Mpro, which supports these candidates and could be potent antiviral agent against SARS-CoV-2.

The molecular docking analysis was performed to understand the binding and intermolecular interactions of the IDX17119 molecule at the thumb-II domain of 1a, 2a, 3a and 4a GT NS5B RdRps. The molecular dynamics simulation has been performed to determine the stability of the ligand–protein complexes. We found GT 1a complex is relatively stable compared with other drug-receptor complexes. The binding free energy calculations and free energy decomposition analysis were carried out for all the complexes, the result revealed that the increase in the unfavourable polar contribution affects the binding of IDX17119 with GT 2a NS5B RdRp compared with all other complexes. In addition to this, the effect of mutation at M423 site (M423T/V) alters the conformation and activity of the IDX17119 molecule.

description: Silver nanoparticles (AgNPs) are useful in various applications due to their unique chemical and physical properties. Therefore, it is important to understand the stability of AgNPs for the development of practical applications. Differently functionalised AgNPs will have different physicochemical properties. This will lead to a variation in the toxicity of these NPs. Different functional groups (FGs) can form coordination bonding or electrostatic interactions with AgNPs. In this study, three different sizes of AgNPs were functionalised by PEG molecules containing five different FGs including methyl, carboxyl, amine, hydroxyl and biotin to investigate the stability of AgNPs in terms of size and FG. The stability was determined by calculating the binding energy of the PEGylated-AgNP system. The results indicate that the stability increases with size, while the influence of the FG was observed to be size-dependent.

description: En esta tesis se ha desarrollado un trabajo sobre la creación de una página web dedicada a la información sobre fútbol. Sin embargo antes de llegar a la fase de creación del website se tomó la decisión hacer un trabajo previo de conocimiento y análisis. La idea de desarrollar esta investigación se basa en la necesidad de conocer porqué (A juicio de la gente) muchos de los sitios web en Colombia dedicados al fútbol son considerados de baja calidad. Para conocer la opinión de la gente se realizaron una serie de encuestas a estudiantes del énfasis de periodismo y cultura entre séptimo y décimo semestre de comunicación social de la Universidad de Cartagena y entrevistas a profesionales del periodismo deportivo para conocer una opinión más especializada sobre la situación.

description: Una vez realizada la investigación al interior de la Iglesia Centro Cristiano de Avivamiento Mundo de Fe, se pudo establecer que la gestión comunicacional es deficiente, porque no es directa y en ella se presentan muchos vacíos, baches o intervalos innecesarios que propician distorsión de los mensajes o ineficacia de la comunicación. Es menester que se implemente la teoría de Henry Fayol sobre comunicación horizontal, para solventar esa carencia de comunicación directa y formalizar flujos de transmisión de mensajes.  La iglesia no posee organigrama donde se evidencie la organización interna, por consiguiente desde ahí se muestran las falencias en la comunicación debido a que la comunicación circula dentro de esta. En crisis solo el apóstol Diomedes ramos debe hablar sobre esta. No cuenta con departamentos designados para la consecución de los objetivos y por consiguiente lograr cumplir la misión. La Iglesia Centro Cristiano de Avivamiento Mundo de Fe, no genera procesos comunicacionales entre los habitantes de la ciudad de Cartagena, por esta razón la imagen que proyecta no está posicionada. El manejo de la comunicación no es el apropiado, dentro de la investigación se evidencio la falta de importancia que le dan a esta área. El flujo de la comunicación no fluye, es carente la información impidiendo un desarrollo favorable de la identidad entre los asistentes. Los resultados encontrados, luego de una indagación en cada proceso comunicacional de la iglesia generan la necesidad de constituir un plan de comunicación que cubra estos requerimientos. Es trascendental ejecutar la estrategia de comunicación que se proponen en el plan de comunicación para cimentar, desarrollar y permitir el crecimiento de la Iglesia Centro Cristiano de Avivamiento Mundo de Fe.

description: “Uno de mis compañeros me amenaza diciendo que no voy a llegar viva a mi casa, que me va a matar… que me va a meter unas puñaladas, tan sólo porque le cogí el puesto”1; esta es una de muchas situaciones que niños, niñas y adolescentes enfrentan a diario en el colegio Mercedes Abrego de San Fernando, nuestro campo de estudio. “La violencia en los centros educativos es un fenómeno que se ha adquirido desde los años setenta, con una gran importancia en países como Estados Unidos, Suecia, Noruega y Reino Unido. En nuestro país parece que su incidencia es menor pero empiezan a detectarse, cada vez más, manifestaciones preocupantes como consecuencia de la crisis social y cultural que se está sufriendo”2. Actualmente, este fenómeno se agrava en los medios de comunicación y los periódicos nos avisan frecuentemente de los sucesos violentos que se presentan en los colegios. Por eso nos preguntamos ¿qué podemos hacer frente al fenómeno de la violencia escolar? es importante tratar de buscar las causas y exponer posibles soluciones para mejorar esta situación, y sin duda alguna, la comunicación social es una herramienta poderosa para fomentar los cambios sociales, tan fuerte que dejar de comunicar, también es comunicar. A través de la comunicación se construyen o se transforman realidades, se influye en el comportamiento del receptor; no existe realidad sin comunicación, por eso a través de estrategias comunicacionales escritas se tiene la obligación de que la construcción que pueda hacer cada sujeto respecto a “su” realidad, contenga la mayor cantidad de elementos para que esta le permita desarrollar y desplegar todas sus potencialidades, es decir, para que las personas puedan expresarse “por sí mismas”; y para lograr que las personas se apropien enteramente de sus vidas, se vuelvan conscientes de su ser y puedan entender el mundo sobre el que actuamos, es fundamental, desde nuestro punto de vista, el trabajo desde la comunicación-educación. Por tanto, esta tesis tiene como fin formar en resolución pacífica de conflictos niños, niñas y adolescentes entre edades de 10 y 15 años, que cursan de sexto a noveno grado de bachillerato en el Colegio Mercedes Abrego ubicado en el barrio San Fernando de la ciudad de Cartagena, a través de una campaña comunicacional escrita, en un tiempo estipulado de dos semanas. De esta manera se convierte en una contribución a la resolución sana de conflictos y/o a la sana convivencia en el ambiente escolar.

description: The exhibition at Milan Triennale, 'Classico Manifesto' concerns the relationship between advertising and history of the classical tradition, whose starting point is the discussion of one of main focuses of western art: the nexus between origina, model and copy. In 'Classico Manifesto', advertising images are investigated from a different perspective: the techniques for constructing these images - and their communicative effectiveness - are traced back to patterns inherent in the creative process of art and to patterns historically attested in the dynamics of cultural tradition.
Strong Coupling in F-theory and Geometrically Non-Higgsable Seven-branes

description: Geometrically non-Higgsable seven-branes carry gauge sectors that cannot be broken by complex structure deformation, and there is growing evidence that such configurations are typical in F-theory. We study strongly coupled physics associated with these branes. Axiodilaton profiles are computed using Ramanujan's theories of elliptic functions to alternative bases, showing explicitly that the string coupling is order one in the vicinity of the brane; that it sources nilpotent $SL(2,\mathbb{Z})$ monodromy and therefore the associated brane charges are modular; and that essentially all F-theory compactifications have regions with order one string coupling. It is shown that non-perturbative $SU(3)$ and $SU(2)$ seven-branes are related to weakly coupled counterparts with D7-branes via deformation-induced Hanany-Witten moves on $(p,q)$ string junctions that turn them into fundamental open strings; only the former may exist for generic complex structure. D3-brane near these and the Kodaira type II seven-branes probe Argyres-Douglas theories. The BPS states of slightly deformed theories are shown to be dyonic string junctions.
