description: Magnetic reconnection and particle acceleration due to the kink instability in twisted coronal loops can be a viable scenario for confined solar flares. Detailed investigation of this phenomenon requires reliable methods for observational detection of magnetic twist in solar flares, which may not be possible solely through extreme UV and soft X-ray thermal emission. Polarisation of microwave emission in flaring loops can be used as one of the detection criteria. The aim of this study is to investigate the effect of magnetic twist in flaring coronal loops on the polarisation of gyro-synchrotron microwave (GSMW) emission, and determine whether it could provide a means for magnetic twist detection. We use time-dependent magnetohydrodynamic and test-particle models developed using LARE3D and GCA codes to investigate twisted coronal loops relaxing following the kink-instability. Synthetic GSMW emission maps (I and V Stokes components) are calculated using GX simulator. It is found that flaring twisted coronal loops produce GSMW radiation with a gradient of circular polarisation across the loop. However, these patterns may be visible only for a relatively short period of time due to fast magnetic reconfiguration after the instability. Their visibility also depends on the orientation and position of the loop on solar disk. Typically, it would be difficult to see these characteristic polarisation pattern in a twisted loop seen from the top (close to the centre of the solar disk), but easier in a twisted loop seen from the side (i.e. observed very close to the limb).

description: A general framework for the kinetic modelling of non-relativistic polyatomic gases is proposed,where each particle is characterized both by its velocity and by its internal state, and the Boltzmann collisionoperator involves suitably weighted integrals over the space of internal energies. The description of the internalstructure of a molecule is kept highly general, and this allows classical and semi-classical models, such asthe monoatomic gas description, the continuous internal energy structure, and the description with discreteinternal energy levels, to fit our framework. We prove the H-Theorem for the proposed kinetic equation ofBoltzmann type in this general setting, and characterize the equilibrium Maxwellian distribution and thethermodynamic number of degrees of freedom. Euler equations are derived, as zero-order approximation in asuitable asymptotic expansion. In addition, within this general framework it is possible to build up new models,highly desirable for physical applications, where rotation and vibration are precisely described. Examples ofmodels for the Hydrogen Fluoride gas are presented.

description: This study analyzed the financial performance of three government-owned universal banks in thePhilippines, namely Land Bank of the Philippines (LBP), Development Bank of the Philippines (DBP) andAl-Amanah Islamic Investment Bank of the Philippines (AAIIBP), from 2012 to 2022. Anchored in theMurtini-Purnama-Lumbantobing hypotheses, the study described the Return on Assets (ROA), CapitalAdequacy Ratio (CAR), and Operating Expense and Operating Income (BOPO) Ratio, Non-PerformanceLoans (NPL), and Interest Rate of the three banks over the study period. Furthermore, it examined theimpact of CAR and BOPO Ratio on ROA, as well as the mediating role of NPL and the moderating role ofInterest Rates on this relationship. Based on the results, policy recommendations were proposed.The study employed an ex-post facto research design, analyzing secondary data from financialstatements, Banks’ annual reports, and BSP reports. While the researcher computed ROA and BOPORatio, the CAR and NPL Ratios were directly sourced from the financial statements and annual reports.Data on Interest rates were derived from BSP's report on Domestic Interest Rates. Data gathered wereanalyzed through line graphs to visually present the trend, Generalized Linear Model (GLM) MediationAnalysis to determine whether the relationship between independent variables (CAR and BOP) on adependent variable (ROA) is mediated by an intermediate variable (NPL), and Moderation Analysis toexamine how the relationship between an independent variable (CAR) and a dependent variable (ROA)changes depending on the level of third variable, known as the moderator variable (Interest Rate).Findings revealed that AIB consistently exhibited negative ROA, highlighting profitabilitychallenges, while LBP and DBP showed positive, though generally below-industry-average, returns. LBPand DBP maintained CAR above the 10% BSP requirement despite fluctuations, while AIB's CAR sharplydeclined from 203.89% in 2012 to 3.43% in 2020. All three banks had higher BOPO ratios than theindustry average. NPL trends varied, with LBP and DBP fluctuating due to market conditions, and AIB'sNPL surging to 18.89% in 2022 after a period of near-zero NPLs. Interest rates, stable from 2012-2017,rose in 2018 due to inflation. CAR had a statistically significant negative impact on ROA (Estimate: -0.013, SE: 0.005, β: -0.124, z: -2.560, p = 0.010), as did BOPO (Estimate: -0.035, SE: 0.002, β: -0.928, z:-19.170, p < 0.001). NPL's mediating effect on both relationships was insignificant (p > 0.35). However,interest rates significantly moderated the CAR-ROA relationship (CAR*IR interaction: Estimate: 19.1631,SE: 8.5281, z: 2.247, p = 0.025). Based on these findings, the researcher proposed policyrecommendations intended to reduce NPLs, including integration of enhanced NPL data analytics and AIbased risk management and promotion of financial education programs for borrowers.

description: In this paper we first compute the out-of-time-order correlators (OTOC) for both a phenomenological model and a random-field XXZ model in the many-body localized phase. We show that the OTOC decreases in power law in a many-body localized system at the scrambling time. We also find that the OTOC can also be used to distinguish a many-body localized phase from an Anderson localized phase, while a normal correlator cannot. Furthermore, we prove an exact theorem that relates the growth of the second Rényi entropy in the quench dynamics to the decay of the OTOC in equilibrium. This theorem works for a generic quantum system. We discuss various implications of this theorem.

description: Given a graph whose arc traversal times vary over time, the Time-Dependent Travelling Salesman Problem consists in finding a Hamiltonian tour of least total duration covering the vertices of the graph. The main goal of this work is to define tight upper bounds for this problem by reusing the information gained when solving instances with similar features. This is customary in distribution management, where vehicle routes have to be generated over and over again with similar input data. To this aim, we devise an upper bounding technique based on the solution of a classical (and simpler) time-independent Asymmetric Travelling Salesman Problem, where the constant arc costs are suitably defined by the combined use of a Linear Program and a mix of unsupervised and supervised Machine Learning techniques. The effectiveness of this approach has been assessed through a computational campaign on the real travel time functions of two European cities: Paris and London. The overall average gap between our heuristic and the best-known solutions is about 0.001\%. For 31 instances, new best solutions have been obtained.

description: Robot manipulation in cluttered scenes often requires contact-rich interactions with objects. It can be more economical to interact via non-prehensile actions, for example, push through other objects to get to the desired grasp pose, instead of deliberate prehensile rearrangement of the scene. For each object in a scene, depending on its properties, the robot may or may not be allowed to make contact with, tilt, or topple it. To ensure that these constraints are satisfied during non-prehensile interactions, a planner can query a physics-based simulator to evaluate the complex multi-body interactions caused by robot actions. Unfortunately, it is infeasible to query the simulator for thousands of actions that need to be evaluated in a typical planning problem as each simulation is time-consuming. In this work, we show that (i) manipulation tasks (specifically pick-and-place style tasks from a tabletop or a refrigerator) can often be solved by restricting robot-object interactions to adaptive motion primitives in a plan, (ii) these actions can be incorporated as subgoals within a multi-heuristic search framework, and (iii) limiting interactions to these actions can help reduce the time spent querying the simulator during planning by up to 40x in comparison to baseline algorithms. Our algorithm is evaluated in simulation and in the real-world on a PR2 robot using PyBullet as our physics-based simulator. Supplementary video: \url{https://youtu.be/ABQc7JbeJPM}.

description: The prospect of using quantum computers to solve combinatorial optimization problems via the quantum approximate optimization algorithm (QAOA) has attracted considerable interest in recent years. However, a key limitation associated with QAOA is the need to classically optimize over a set of quantum circuit parameters. This classical optimization can have significant associated costs and challenges. Here, we provide an expanded description of Lyapunov control-inspired strategies for quantum optimization, as presented in [Magann et al., Phys. Rev. Lett. 129, 250502 (2022)], that do not require any classical optimization effort. Instead, these strategies utilize feedback from qubit measurements to assign values to the quantum circuit parameters in a deterministic manner, such that the combinatorial optimization problem solution improves monotonically with the quantum circuit depth. Numerical analyses are presented that investigate the utility of these strategies towards MaxCut on weighted and unweighted 3-regular graphs, both in ideal implementations and also in the presence of measurement noise. We also discuss how how these strategies compare with QAOA, how they may be used to seed QAOA optimizations in order to improve performance for near-term applications, and explore connections to quantum annealing.

description: Particle in Cell (PIC) simulations are a widely used tool for the investigation of both laser- and beam-driven plasma acceleration. It is a known issue that the beam quality can be artificially degraded by numerical Cherenkov radiation (NCR) resulting primarily from an incorrectly modeled dispersion relation. Pseudo-spectral solvers featuring infinite order stencils can strongly reduce NCR, or even suppress it, and are therefore well suited to correctly model the beam properties. For efficient parallelization of the PIC algorithm, however, localized solvers are inevitable. Arbitrary order pseudo-spectral methods provide this needed locality. Yet, these methods can again be prone to NCR. Here, we show that acceptably low solver orders are sufficient to correctly model the physics of interest, while allowing for parallel computation by domain decomposition.

description: Using the perturbative QCD approach, we studied the effects from hadronic structure of photon on the pure annihilation rediative decays $B\toϕγ$ and $B_s\to(ρ^0,ω)γ$. These decays have small branching fractions due to the power suppression by the $Λ/m_B$, which make them very sensitive to the next-leading power corrections. The quark components and the related two-particle distribution amplitudes of a final state photon are introduced. The branching fractions can be enhanced remarkably by the factorizable and nonfactorizable emission diagrams. The branching fraction of $B\to ϕγ$ even increases by about 40 times, and those of $B_s \to ρ^0γ$ and $B_s \to ωγ$ are at the order of ${\cal O}(10^{-10})$. We also note that the ratio of branching fractions of $B_s \to ρ^0γ$ and $B_s \to ωγ$ is very sensitive to the effects from hadronic structure of photon. All above results could be tested in future.

description: This thesis investigated the phytochemical and pharmacological properties of four medicinal plants: Anagallis arvensis, Bougainvillea glabra, Buxus papillosa, and Filago germanica. Phytochemical screening was performed by total bioactive contents, UHPLC-MS, and HPLC analysis. Antioxidant potential was determined by DPPH, ABTS, CUPRAC, FRAP, TAC, and MCA assays. Inhibitory activities were tested against cholinesterases, α-glucosidase, α-amylase, urease, LOX, and tyrosinase enzymes. Anticancer activity was tested on MCF-7, MDA-MB-231, CaSki, DU-145, and SW-480 cell lines. The active extracts resulted in isolation of 5,7,3'-trihydroxy-6,4',5'-trimethoxyflavone, 5-hydroxy-3, 7-dimethoxy-2-(4'-methoxyphenyl)-flavone, 5,7-dihydroxy-2-(5’-hydroxy-3’, 4’-dimethoxyphenyl)-flavone, β-sitosterol, and 3-(2’-hydroxy-4’, 5’-dimethoxyphenyl)-8-methoxy-isoflavone. The studied plants can be considered as promising origin for natural compounds.

description: In hydrodynamical modeling of ultrarelativistic heavy-ion collisions, the freeze-out is typically assumed to take place at a surface of constant temperature or energy density. A more physical approach is to assume that freeze-out takes place at a surface of constant Knudsen number. We evaluate the Knudsen number as a ratio of the expansion rate of the system to the pion scattering rate, and apply the constant Knudsen number freeze-out criterion to ideal hydrodynamical description of heavy-ion collisions at RHIC ($\sqrt{s_\mathrm{NN}}=200$ GeV) and the LHC ($\sqrt{s_\mathrm{NN}}=2760$ GeV) energies. We see that once the numerical values of freeze-out temperature and freeze-out Knudsen number are chosen to produce similar $p_T$ distributions, the elliptic and triangular anisotropies are similar too, in both event-by-event and averaged initial state calculations.

description: Capital as a requirement for economic growth is satisfied mainly by the development of financial sector in an economy. This research was undertaken with the objective of assessing the challenges of project financing in Commercial Bank of Ethiopia. To this end, the study employed quantitative and qualitative research approach; descriptive design to construct meaning from extracted data collected from primary and second sources through survey and document review. This was supplemented by available books, documents, published and unpublished thesis. Accordingly, the study came up with the findings that challenges CBE was facing in project financing emanate from three categories. The study, hence, concluded project financing challenges in CBE were external environment specific (data/information, financial intermediaries, economic & political environment and infrastructure), borrower specific (character of the borrower, nature of the project and management problem of the project promoter) and bank related (character of the bank, credit policy and procedure and credit appraisal & approval) in decreasing order of mean value of major category. From the reached conclusion in the study, it is recommended the bank and concerned parties should take respective actions to tackle the challenges timey.

description: We construct a state-sum type invariant of smooth closed oriented $4$-manifolds out of a $G$-crossed braided spherical fusion category ($G$-BSFC) for $G$ a finite group. The construction can be extended to obtain a $(3+1)$-dimensional topological quantum field theory (TQFT). The invariant of $4$-manifolds generalizes several known invariants in literature such as the Crane-Yetter invariant from a ribbon fusion category and Yetter's invariant from homotopy $2$-types. If the $G$-BSFC is concentrated only at the sector indexed by the trivial group element, a cohomology class in $H^4(G,U(1))$ can be introduced to produce a different invariant, which reduces to the twisted Dijkgraaf-Witten theory in a special case. Although not proven, it is believed that our invariants are strictly different from other known invariants. It remains to be seen if the invariants are sensitive to smooth structures. It is expected that the most general input to the state-sum type construction of $(3+1)$-TQFTs is a spherical fusion $2$-category. We show that a $G$-BSFC corresponds to a monoidal $2$-category with certain extra structure, but that structure does not satisfy all the axioms of a spherical fusion $2$-category given by M. Mackaay. Thus the question of what axioms properly define a spherical fusion $2$-category is open.

A esta problemática, se suma el hecho de que muchos de los estudiantes no cuentan con acompañamiento de sus familias, ya sea por cuestiones laborales o en el peor de los casos, por analfabetismo de los padres. Esta propuesta investigativa se fundamentó en el modelo cualitativo, con un modelo de investigación acción pedagógica que, permitiera mejorar la problemática planteada. La integración de nuevas herramientas tecnológicas en el proyecto pedagógico, nos permitió sistematizar el diagnóstico inicial de la problemática expuesta. Dicho diagnóstico, al comienzo muestra un resultado muy bajo en la comprensión lectora, donde solo un 15,6% de los estudiantes comprendían e interpretaban textos. Se puede demostrar que, con la implementación del proyecto, se ha venido avanzando y en la actualidad el 75% de los jóvenes comprenden e interpretan textos, ubicándose en un nivel más avanzado de la comprensión lectora. Para el desarrollo de esta investigación, se diseñó y se implementó un blog educativo, demostrándose su efectividad en el proceso de mejoramiento de la comprensión lectora, ya que al comparar los datos obtenidos en la fase diagnóstica y la fase final se observan resultados favorables en los diferentes niveles de comprensión, lo que demuestra que la aplicación de la secuencia didáctica en el recurso educativo digital, fue pertinente para darle solución a la problemática planteada. Con los resultados obtenidos en las diferentes fases de la propuesta investigativa podemos concluir que, se fortaleció y se alcanzó un alto nivel de desempeño en la comprensión lectora mediada por el uso de la herramienta tecnológica Edublog o blog educativo.

description: The Charlson Comorbidity Index (CCI) and prognostic nutritional index (PNI) have proven to be valuable tools in predicting prognosis based on comorbidities and nutritional status in the context of surgical procedures and endoscopic resections. The age-Adjusted CCI (ACCI) has also shown utility in surgical settings, but its application to early gastric cancer (EGC) remains unexplored. Consequently, we aimed at clarifying the prognostic factors for EGC treated with endoscopic submucosal dissection (ESD). Patients who underwent ESD for EGC at the First Affiliated Hospital of Dalian Medical University from January 2015 to February 2023 were included. The overall survival (OS) and prognostic predictive ability were evaluated based on patients and lesion characteristics. During a median follow-up period of 50 months, 15 patients died, but none from the gastric cancer. The 5-year survival rate was 90.0%. In univariate and multivariate analyses, a high ACCI (>4.5) was the only significant prognostic factor (Hazard ratio, 27.78; 95% confidence interval, 3.62–213.40; p < 0.01). The 5-year survival rates for patients with low ACCI (<4.5) and high ACCI were 98.9% and 72.9%, respectively (p < 0.01). A high ACCI is a significant prognostic indicator for 5-year survival and the risk of mortality caused by other comorbidities. EGC suitable for ESD is unlikely to serve as a prognostic factor, and ACCI should be considered as an important reference when considering additional surgical procedures in high-ACCI patients after ESD with endoscopic curability (eCura) C-2 for EGC.

description: The present study investigates whether liquidity premia can explain deviations from uncovered interest parity. For that purpose I modify a representative agent asset-pricing model by assuming that investors value liquidity services which are unique features of U.S. Treasuries. Further the assumption that domestic and foreign bonds are perfect substitutes is relaxed. Estimation results for U.S. and U.K. data provide support for the hypothesis that investors valuation for U.S. Treasuries liquidity contributes to explain deviations from uncovered interest parity. In contrast to most forward premium regression estimations, I find a positive association between the expected depreciation rate of the U.S. currency relative to the UK currency and the U.S.-U.K. Treasury yield spread.

description: While measurement-device-independent (MDI) quantum key distribution (QKD) allows two trusted parties to establish a shared secret key from a distance without needing to trust a central detection node, their quantum sources must be well-characterized, with side-channels at the source posing the greatest loophole to the protocol's security. In this paper, we identify a time-dependent side-channel in a common polarization-based QKD source that employs a Faraday mirror for phase stabilization. We apply the recently developed numerical proof technique from [Phys. Rev. A 99, 062332 (2019)] to quantify the sensitivity of the secret key rate to the quantum optical model for the side-channel, and to develop strategies to mitigate the information leakage. In particular, we find that the MDI three-state and BB84 protocols, while yielding the same key rate under ideal conditions, have diverging results in the presence of a side-channel, with BB84 proving more advantageous. While we consider only a representative case example, we expect the strategies developed and key rate analysis method to be broadly applicable to other leaky sources.

description: We apply the method of controlled Lagrangians by potential shaping to Euler--Poincaré mechanical systems with broken symmetry. We assume that the configuration space is a general semidirect product Lie group $\mathsf{G} \ltimes V$ with a particular interest in those systems whose configuration space is the special Euclidean group $\mathsf{SE}(3) = \mathsf{SO}(3) \ltimes \mathbb{R}^{3}$. The key idea behind the work is the use of representations of $\mathsf{G} \ltimes V$ and their associated advected parameters. Specifically, we derive matching conditions for the modified potential exploiting the representations and advected parameters. Our motivating examples are a heavy top spinning on a movable base and an underwater vehicle with non-coincident centers of gravity and buoyancy. We consider a few different control problems for these systems, and show that our results give a general framework that reproduces our previous work on the former example and also those of Leonard on the latter. Also, in one of the latter cases, we demonstrate the advantage of our representation-based approach by giving a simpler and more succinct formulation of the problem.

description: In the present research, we fabricated and characterized the self-assembled sodium caseinate nanomicelles (NaCNs) successfully followed by loading of Paclitaxel (PTX) and Doxorubicin (DOX) into the casein micelle for higher cellular uptake and cytoxicity and further explored antitumour efficacy and biodistribution studies of NaCNs and drug-loaded NaCNs against a murine breast cancer model, where both PTX- and DOX-loaded NaCNs showed enhanced in vivo antitumour efficacy through inhibition of tumour growth. Thus NaCNs can be suggested as safe and non-toxic delivery system with excellent anti-tumour efficacy and can be a potential option for oral chemotherapy.

description: La primera infancia es una población de gran importancia, por ello en Colombia con el trascurrir del tiempo ha aumentado el desarrollo de normas, leyes, programas, proyectos, que promueven y protegen los derechos y el bienestar de dicha población, sin embargo existen comunidades del país en las que sus derechos son vulnerados. La finalidad de este documento es mostrar los factores sociales que inciden en el proceso de garantía de los derechos de los niños y niñas beneficiarios de los hogares infantiles comunitarios La Abejita de Membrillal y San Lucas de Cartagena, para ello se realizó un estudio a las familias beneficiarias de estas dos instituciones, en las cuales se llevaron a cabo visitas domiciliarias en las que se pusieron en práctica un formato de entrevistas y una ficha de caracterización socio familiar. Los hallazgos e información obtenida fueron sistematizados y plasmados en el presente estudio, para facilitar la comprensión del lector organizamos la información de tal manera que se observa una comparación social de las familias beneficiarias de los hogares infantiles, teniendo en cuenta que los contextos y estratos sociales de estas familias son diferentes.
Multivariable Adaptive Harmonic Steady-State Control for Rejection of Sinusoidal Disturbances Acting on an Unknown System

description: This paper presents an adaptive harmonic steady-state (AHSS) controller, which addresses the problem of rejecting sinusoids with known frequencies that act on a completely unknown multi-input multi-output linear time-invariant system. We analyze the stability and closed-loop performance of AHSS for single-input single-output systems. In this case, we show that AHSS asymptotically rejects disturbances.

Practices & Challenges Of Stakeholder Management: The Case Of Addis Ababa Housing Construction Project At "Akaki-Kality" Project Site
Creators: name: Tesfaye, Aklile
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: This study aims to identify roles of stakeholders who have definable influence on the delivery of Housing construction project at "Akaki-kality" project site. Four specific objectives were set accordingly: to identify the types, responsibilities and interests of different stakeholders' during construction of Addis Ababa Housing construction project; to identify the most common factors affecting the stakeholder management process in the construction project; to investigate the challenges associated with managing various stakeholder expectations and influences; and to assess the effectiveness of stakeholder management. A literature reviews on the topic related to the stakeholder management was conducted. The research used descriptive research design and a mixed method of qualitative and quantitative approaches. The study also used both primary and secondary data sources. A questionnaire survey was carried out among selected project participants in the construction project site. Thirty-two questionnaires were distributed to HDPO, contractors, consultants and MSE's, all the questionnaires were received with a 100% response rate. Project participants who have role identified and described their roles and responsibilities. The main factors affecting the stakeholder management process are hiring a project management team with high competency, transparent evaluation of the alternative solution, ensuring effective communication between the project and its stakeholder, setting common goal and objective of the project, and exploring the stakeholder need and expectation. The client/HDPO/ and Finance institute are the main key stakeholders, who have the most influence in the construction project at 'Akaki-Kality' housing construction of Addis Ababa. Also assessed the effectiveness of stakeholder management in the construction project. One of the main recommendations of this study is the HDPO has to recruit the project managing team based on their competencies and to delegate them a suitable degree of authority to lead the management process of the stakeholder successfully. The study also recommended HDPO in collaboration with "Akaki-kality" sub-city should provide training courses to the project management team in the area of communication and negotiation with stakeholders in order to increase their awareness regarding this issue.

description: We study the semigroup $\boldsymbol{B}_ω^{\mathscr{F}}$, which is introduced in [O. Gutik and M. Mykhalenych, \emph{On some generalization of the bicyclic monoid}, Visnyk Lviv. Univ. Ser. Mech.-Mat. \textbf{90} (2020), 5--19], in the case when the family $\mathscr{F}$ of subsets of cardinality $\leqslant 1$ in $ω$. We show that $\boldsymbol{B}_ω^{\mathscr{F}}$ is isomorphic to the subsemigroup $\mathscr{B}_ω^{\Rsh}(\boldsymbol{F}_{\min})$ of the Brandt $ω$-extension of the semilattice $\boldsymbol{F}_{\min}$ and describe all shift-continuous feebly compact $T_1$-topologies on the semigroup $\mathscr{B}_ω^{\Rsh}(\boldsymbol{F}_{\min})$. In particulary we prove that every shift-continuous feebly compact $T_1$-topology $τ$ on $\mathscr{B}_ω^{\Rsh}(\boldsymbol{F}_{\min})$ is compact and moreover in this case the space $(\mathscr{B}_ω^{\Rsh}(\boldsymbol{F}_{\min}),τ)$ is homeomorphic to the one-point Alexandroff compactification of the discrete countable space $\mathfrak{D}(ω)$. We study the closure of $\boldsymbol{B}_ω^{\mathscr{F}}$ in a semitopological semigroup. In particularly we show that $\boldsymbol{B}_ω^{\mathscr{F}}$ is algebraically complete in the class of Hausdorff semitopological inverse semigroups with continuous inversion, and a Hausdorff topological inverse semigroup $\boldsymbol{B}_ω^{\mathscr{F}}$ is closed in any Hausdorff topological semigroup if and only if the band $E(\boldsymbol{B}_ω^{\mathscr{F}})$ is compact.
