description: In this paper we analyse both the dynamics and the high density physics of the infinite dimensional lattice gas model for random heteropolymers recently introduced in \cite{jort}. Restricting ourselves to site-disordered heteropolymers, we derive exact closed deterministic evolution equations for a suitable set of dynamic order parameters (in the thermodynamic limit), and use these to study the dynamics of the system for different choices of the monomer polarity parameters. We also study the equilibrium properties of the system in the high density limit, which leads to a phase diagram exhibiting transitions between swollen states, compact states, and regions with partial compactification. Our results find excellent verification in numerical simulations, and have a natural and appealing interpretation in terms of real heteropolymers.

description: We study the physical properties of the ionized gas in local disks using the sample of 38 nearby $\sim10^{8.5-11.2}$M$_\odot$ Star-Forming Main Sequence (SFMS) galaxies observed so far as part of the MUSE Atlas of Disks (MAD). Specifically, we use all strong emission lines in the MUSE wavelength range 4650-9300 Å to investigate the resolved ionized gas properties on $\sim$100 pc scales. This spatial resolution enables us to disentangle HII regions from the Diffuse Ionized Gas (DIG) in the computation of gas metallicities and Star Formation Rates (SFRs) of star forming regions. The gas metallicities generally decrease with radius. The metallicity of the HII regions is on average $\sim$0.1 dex higher than that of the DIG, but the metallicity radial gradient in both components is similar. The mean metallicities within the inner galaxy cores correlate with the total stellar mass of the galaxies. On our <100 pc scales, we find two correlations previously reported at kpc scales: a spatially resolved Mass-Metallicity Relation (RMZR) and a spatially resolved SFMS (RSFMS). We find no secondary dependency of the RMZR with the SFR density. We find that both resolved relations have a local origin, as they do not depend on the total stellar mass. The observational results of this paper are consistent with the inside-out scenario for the growth of galactic disks.

description: A spectroscopic study was carried out on the surface chemical abundances of CNO and several heavier elements in the primary and secondary components of 5 eclipsing close binaries around A-type (AR Aur, beta Aur, YZ Cas, WW Aur, and RR Lyn), in order to investigate the nature of chemical differences between both components (being comparatively slow rotators alike due to tidal synchronization). Regarding the systems comprising similar components, beta Aur and WW Aur were confirmed to exhibit no compositional difference between the primary and secondary both showing almost the same Am anomaly, though the chemical peculiarities seen in the component stars of AR Aur show distinct differences (HgMn star and Am star). In contrast, as to the systems (YZ Cas and RR Lyn) consisting of considerably different (A and early-F) components, the surface abundances are markedly different between the primary (Am) and secondary (normal). These observational results may indicate Teff-dependent characteristics regarding the chemical anomalies of non-magnetic stars on the upper main sequence: (1) In the effective temperature range of 10000K > Teff > 7000K, rotational velocity is the most important factor for determining the extent of Am peculiarity. (2) However, the emergence of Am phenomenon seems to have a lower Teff limit at ~7000K, below which no abundance anomaly is observed regardless of stellar rotation. (3) The transition from Am anomaly (mild deficiency in CNO) to HgMn anomaly (unusually large N depletion) is likely to take place as Teff increases from ~10000K to ~11000K.

By mapping the problem to that of a directed homopolymer in higher-dimensional random media, we show that the pattern-matching phase is asymptotically weakly unstable, and the large scale properties of the system are given by that of an adsorbed homopolymer.

Can the $ψ(4040)$ explain the peak associated with $Y(4008)$?

description: We study the well-known resonance $ψ(4040)$, corresponding to a $3^{3}S_{1}$ charm-anticharm vector state $ψ(3S)$, within a QFT approach, in which the decay channels into $DD$, $D^{\ast}D$, $D^{\ast}D^{\ast}$, $D_{s}D_{s}$ and $D_{s}^{\ast}D_{s}$ are considered. The spectral function shows sizable deviations from a Breit-Wigner shape (an enhancement, mostly generated by $DD^{\ast}$ loops, occurs); moreover, besides the $c\bar{c}$ pole of $ψ(4040)$, a second dynamically generated broad pole at $4$ GeV emerges. Naively, it is tempting to identify this new pole with the unconfirmed state $Y(4008).$ Yet, this state was not seen in the reaction $e^{+}e^{-}\rightarrowψ(4040)\rightarrow DD^{\ast}$, but in processes with $π^{+}π^{-}J/ψ$ in the final state. A detailed study shows a related but different mechanism: a broad peak at $4$ GeV in the process $e^{+}e^{-}\rightarrowψ(4040)\rightarrow DD^{\ast }\rightarrowπ^{+}π^{-}J/ψ$ appears when $DD^{\ast}$ loops are considered. Its existence in this reaction is not necessarily connected to the existence of a dynamically generated pole, but the underlying mechanism - the strong coupling of $c\bar{c}$ to \ $DD^{\ast}$ loops - can generate both of them. Thus, the controversial state $Y(4008)$ may not be a genuine resonance, but a peak generated by the $ψ(4040)$ and $D^{\ast}D$ loops with $π^{+}π^{-}J/ψ$ in the final state.

description: Creep is a phenomenon that can occur in wooden structures since wood is a viscoelastic material. Creep may change the purely elastic parameters determined in wood characterization initial tests, as its behavior depends on the rheology of the material, even under a constant stress level. Mathematically, creep can be characterized by models in which the immediate elastic deformation is increased by a viscous deformation, resulting in a temporal function. For this reason, the calculation of the natural frequency of vibration and the stability verification of a slender column should include the reducing effects of stiffness both of axial force and creep. The first one can be considered through the geometrical portion and the second one by the introduction, in the conventional portion, of a variable elasticity modulus over time, obtained in relation to the adopted rheological model. A numerical simulation was performed to evaluate the aspects above, considering a bar compressed by a force at the free end equivalent to 10% of the Euler critical force, plus its own weight, adopting a rheological model with three parameters for the variation of the elasticity modulus. The results show differences of 60% and 50% for the frequency and elasticity modulus, besides defining the exact instant of column collapse in the case of its non-observance.
Gravitational waves, black holes and cosmic strings in cylindrical symmetry

description: Gravitational waves in cylindrically symmetric Einstein gravity are described by an effective energy tensor with the same form as that of a massless Klein- Gordon field, in terms of a gravitational potential generalizing the Newtonian potential. Energy-momentum vectors for the gravitational waves and matter are defined with respect to a canonical flow of time. The combined energy-momentum is covariantly conserved, the corresponding charge being the modified Thorne energy. Energy conservation is formulated as the first law expressing the gradient of the energy as work and energy-supply terms, including the energy flux of the gravitational waves. Projecting this equation along a trapping horizon yields a first law of black-hole dynamics containing the expected term involving area and surface gravity, where the dynamic surface gravity is defined with respect to the canonical flow of time. A first law for dynamic cosmic strings also follows. The Einstein equation is written as three wave equations plus the first law, each with sources determined by the combined energy tensor of the matter and gravitational waves.

description: Analyzing the effective conformal field theory for the parafermionic Hall states, corresponding to filling fractions nu_k=2+k/(kM+2), k=2,3,..., M odd, we show that the even k plateaux are expected to be more stable than their odd k neighbors. The reason is that the parafermion chiral algebra can be locally extended for k even. This reconciles the theoretical implication, that the bigger the k the less stable the fluid, with the experimental fact that, for M=1, the k=2 and k=4 plateaux are already observed at electron temperature T_e~8 mK, while the Hall resistance for k=3 is not precisely quantized at that temperature in the sample of Pan et al. Using a heuristic gap ansatz we estimate the activation energy gap for nu_3=13/5 to be approximately 0.015 K, which implies that the quantization of the Hall conductance could be observed for temperature below 1 mK in the same sample. We also find an appealing exact relation between the fractional electric charge and fractional statistics of the quasiholes. Finally, we argue that besides the Moore-Read phase for the nu_2=5/2 state there is another relevant phase, in which the fundamental quasiholes obey abelian statistics and carry half-integer electric charge.

description: Abstract

The research raises critical concerns regarding the declining tax realization and widespread tax avoidance, resulting in substantial revenue losses for the state. Additionally, it underscores the need for improved tax policy implementation and greater societal awareness to address these issues and enhance taxpayer compliance, ultimately optimizing regional or state revenues from the tax sector. This research aimed to analyze the influence of socialization, information technology, attitudes, knowledge and abilities on Taxpayer Compliance with awareness, volition as intervening, and tax avoidance as moderation on individual taxpayers in the city of Surabaya. This research employs an explanatory design. The population for this study consists of individual taxpayers registered with the KPP East Java Region I, totaling 3,042,548 people in 2020. A sample of 400 respondents was chosen using the Slovin formula to represent this population. Data analysis was conducted using Smart PLS. We found that socialization positively influenced taxpayer awareness, negatively impacted volition and taxpayer compliance. Information technology had mixed effects, showing insignificant influence on some factors. Attitude significantly affected awareness and volition but had an insignificant influence on compliance. Knowledge strongly influenced awareness, volition, and taxpayer compliance. The ability to pay taxes had a positive impact on awareness, volition, and taxpayer compliance. Additionally, awareness and volition had mixed influences on taxpayer compliance when moderated by tax avoidance. These findings confirm or contradict previous research regarding taxpayer behavior and compliance.

description: This study examined the contributions of social capital to banana/plantain production in Irewole local Government Area, Osun State. Social capital can be said to be an asset needed by banana/plantain producers to expand their production in order to boost their household food security and ensure sustainable livelihood contributing to the overall food security of the nation. Respondents were also divided into various social classes, according to the report. The sample for the analysis was chosen using a multistage sampling technique. Three rural based wards were purposively selected while two villages from each ward were purposively selected. Making a total of 110 respondents selected.. Descriptive statistics such as pie and bar charts were used to summarize the data while inferential statistical tools such as chi-square and regression analysis were used to analyze the data. 36.0% of respondents fell between the age group of 60-69 years. Banana/plantain producers were male dominated (94.0%). 97.0% of the respondents belong to religious groups while 6.0% belong to non-governmental organization (NGO). Chi-square analysis showed that gender, marital status, age, religion, size of household, farm size and year of experience (χ2 = 83.782, 106.036, 103.0, 52.509, 64.909, 134.200, 159.208; P < 0.05) were all statistically significant to contributions of social capital respectively. It is concluded that social capital played a significant role in banana/plantain production among rural residents. As a result, the use of social capital to supplement limited financial capital for increased food production should be encouraged.

description: A methodology for determining the scattered Electromagnetic (EM) fields present for interconnected regions with common metasurface boundaries is presented. The method uses a Boundary Element Method (BEM) formulation of the frequency domain version of Maxwell's equations - which expresses the fields present in a region due to surface currents on the boundaries. Metasurface boundaries are represented in terms of surface susceptibilities which when integrated with the Generalized Sheet Transition Conditions (GSTCs), gave rise to an equivalent configuration in terms of electric and magnetic currents. Such a representation is then naturally incorporated into the BEM methodology. Two examples are presented for EM scattering of a Gaussian beam to illustrate the proposed method. In the first example, metasurface is excited with a diverging Gaussian beam, and the scattered fields are validated using a semi-analytical method. Second example concerned with a non-uniform metasurface modeling a diffraction grating, whose results were confirmed with conventional Finite Difference Frequency Domain (FDFD) method.

description: In a growing number of galaxy clusters diffuse extended radio sources have been found. These sources are not directly associated with individual cluster galaxies. The radio emission reveal the presence of cosmic rays and magnetic fields in the intracluster medium (ICM). We classify diffuse cluster radio sources into radio halos, cluster radio shocks (relics), and revived AGN fossil plasma sources. Radio halo sources can be further divided into giant halos, mini-halos, and possible `intermediate' sources. Halos are generally positioned at cluster center and their brightness approximately follows the distribution of the thermal ICM. Cluster radio shocks (relics) are polarized sources mostly found in the cluster's periphery. They trace merger induced shock waves. Revived fossil plasma sources are characterized by their radio steep-spectra and often irregular morphologies. In this review we give an overview of the properties of diffuse cluster radio sources, with an emphasis on recent observational results. We discuss the resulting implications for the underlying physical acceleration processes that operate in the ICM, the role of relativistic fossil plasma, and the properties of ICM shocks and magnetic fields. We also compile an updated list of diffuse cluster radio sources which will be available on-line http://galaxyclusters.com. We end this review with a discussion on the detection of diffuse radio emission from the cosmic web.

description: Multiple-choice questions (MCQs) are frequently used for formative assessment in medical school but often lack sufficient answer explanations given time-restraints of faculty. Chat Generated Pre-trained Transformer (ChatGPT) has emerged as a potential student learning aid and faculty teaching tool. This study aims to evaluate ChatGPT’s performance in answering and providing explanations for MCQs. Ninety-four faculty-generated MCQs were collected from the pre-clerkship curriculum at a US medical school. ChatGPT’s accuracy in answering MCQ’s were tracked on first attempt without an answer prompt (Pass 1) and after being given a prompt for the correct answer (Pass 2). Explanations provided by ChatGPT were compared with faculty-generated explanations, and a 3-point evaluation scale was used to assess accuracy and thoroughness compared to faculty-generated answers. On first attempt, ChatGPT demonstrated a 75% accuracy in correctly answering faculty-generated MCQs. Among correctly answered questions, 66.4% of ChatGPT's explanations matched faculty explanations, and 89.1% captured some key aspects without providing inaccurate information. The amount of inaccurately generated explanations increases significantly if the questions was not answered correctly on the first pass (2.7% if correct on first pass vs. 34.6% if incorrect on first pass, p < 0.001). ChatGPT shows promise in assisting faculty and students with explanations for practice MCQ’s but should be used with caution. Faculty should review explanations and supplement to ensure coverage of learning objectives. Students can benefit from ChatGPT for immediate feedback through explanations if ChatGPT answers the question correctly on the first try. If the question is answered incorrectly students should remain cautious of the explanation and seek clarification from instructors.

description: The field of medical education has seen a growing interest in lecture free curriculum. However, it comes with its own set of challenges and obstacles. In this article, we aim to identify the prerequisites, facilitators, challenges, and barriers of lecture-free curriculum in medical education and examine their interrelationships using interpretive structural modeling (ISM) technique. In this mixed-method study initially, we performed a scoping review and semi-structured interviews and determined the main prerequisites, facilitators, challenges, and barriers of lecture-free curriculum in medical education using qualitative content analysis approach. The interrelationships among these components were investigated using ISM. Therefore, self-interactive structural matrices were formed, initial and final reachability matrices were achieved, and MICMAC analysis was conducted to classify the factors. Finally, two ISM models of prerequisites and facilitators with 27 factors in 10 levels and challenges and obstacles with 25 factors in eight levels were developed. Each of the models was divided into three parts: key, strategic, and dependent factors. ‘Providing relevant evidence regarding lecture free curriculum’ emerged as the most important prerequisite and facilitator, and ‘insufficient support from the university’ was identified as the most critical barrier and challenge. The study highlights the significant importance of lecture-free curriculum in medical education and provides insights into its prerequisites, facilitators, challenges, and barriers. The findings can be utilized by educational managers and decision-makers to implement necessary changes in the design and implementation of lecture-free in medical education, leading to more effective improvements in the quality and success of education.

description: With the increased application of large eddy simulation techniques, the generation of realistic turbulence at inflow boundaries is crucial for the accuracy of a simulation. The Control Forced Concurrent Precursor Method (CFCPM) proposed in this work combines an existing concurrent precursor method and a mean flow forcing method with a new extension of the controlled forcing method to impose turbulent inflow boundary conditions primarily, although not exclusively, for domains that require periodic boundary conditions. Turbulent inflow boundary conditions are imposed through a region of body forces added to the momentum equations of the main simulation that transfers the precursor simulation into the main domain. Controlled forcing planes, which come into play as body forces added to the momentum equations on planes perpendicular to the flow, located in the precursor simulation, allow for specific Reynolds stress tensors and mean velocities to be imposed. The mean flow controlled forcing method only modifies the mean velocity profiles, leaving the fluctuating velocity field untouched. The proposed fluctuating flow controlled forcing methods extends the application of the original controlled forcing method to multiple fluctuating velocity components and couples their calculation in order to amplify the existing fluctuations present in the precursor flow field so that prescribed anisotropic Reynolds stress tensors can be reproduced. The new method was tested on high Reynolds number turbulent boundary layer flow over a wall-mounted cube and low Reynolds number turbulent boundary layer flow over a backward-facing step. It was found that the new extension of the controlled forcing method reduced the development time for both test cases considered here when compared to not using controlled forcing and only using the original controlled forcing method.

description: We present an operator based factorization formula for the transverse energy-energy correlator (TEEC) hadron collider event shape in the back-to-back (dijet) limit. This factorization formula exhibits a remarkably symmetric form, being a projection onto a scattering plane of a more standard transverse momentum dependent factorization. Soft radiation is incorporated through a dijet soft function, which can be elegantly obtained to next-to-next-to-leading order (NNLO) due to the symmetries of the problem. We present numerical results for the TEEC resummed to next-to-next-to-leading logarithm (NNLL) matched to fixed order at the LHC. Our results constitute the first NNLL resummation for a dijet event shape observable at a hadron collider, and the first analytic result for a hadron collider dijet soft function at NNLO. We anticipate that the theoretical simplicity of the TEEC observable will make it indispensable for precision studies of QCD at the LHC, and as a playground for theoretical studies of factorization and its violation.

description: The assembly of aligned carbon nanotubes (CNT) into fibers (CNTF) is a convenient approach to exploit and apply the unique physico-chemical properties of CNTs in many fields. CNT functionalization has been extensively used for their implementation into composites and devices. However, CNTF functionalization is still in its infancy, due to the challenges associated with preservation of CNTF morphology. Here, we report a thorough study of the gas-phase functionalization of CNTF fabrics using ozone that was generated in situ from a UV-source. By contrast with liquid-based oxidation methods, this gas-phase approach preserves CNTF morphology, whilst notably increasing its hydrophilicity. The functionalized material is thoroughly characterized by Raman, XPS, TEM and SEM. Its newly acquired hydrophilicity enables CNTF electrochemical characterization in aqueous media, which was not possible for the pristine material. Through comparison of electrochemical measurements in aqueous electrolyte and ionic liquid we decouple the effects of functionalization on pseudocapacitive reactions and quantum capacitance. The functionalized CNTF fabric is successfully used as active material and current collector in all-solid supercapacitor flexible devices with ionic liquid-based polymer electrolyte.

description: A field experiment was carried out to study the performance of All India Co-Ordinated Vegetable Improvement Project (AICVIP) hybrid trials (IET,AVT-I and AVT-II) on growth, yield and quality of Bhendi (Abelmoschus esculentus L. Moench) from 2012 to 2014 at the Department of Vegetable Crops, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore, India. The seeds of the okra hybrid (IET, AVT-I and AVT-II) entries were chosen for this study. Okra is one of the most important vegetable crops grown for its tender green fruits during summer and rainy seasons. The results based on Bhendi hybrids trials mean revealed that different hybrid entries were applied in three replications. Among the entries tested (IET), the highest fruit yield (226.5 q/ha) was recorded in 2014/OKHYB-4 followed by 2014/OKHYB-6 (200.4 q/ha), the results revealed that (AVT-I) the highest fruit yield (243.5 q/ha) was recorded in 2013/OKHYB-9 followed by 2013/OKHYB-10 (224.6 q/ha). Among the entries tested (AVT-II), the highest fruit yield (238.7 q/ha) was recorded in 2012/OKHYB-13 followed by 012/OKHYB-15 (225.4 q/ha.).

description: An understanding of the normal state in the high-temperature superconducting cuprates is crucial to the ultimate understanding of the long-standing problem of the origin of the superconductivity itself. This so-called strange metal state is thought to be associated with a quantum critical point (QCP) hidden beneath the superconductivity(1,2). In electron-doped cuprates in contrast to hole-doped cuprates it is possible to access the normal state at very low temperatures and low magnetic fields to study this putative QCP and to probe the T~0 K state of these materials(3,4). We report measurements of the low temperature normal state magnetoresistance (MR) of the n-type cuprate system La2-xCexCuO4 (LCCO) and find that it is characterized by a linear-in-field behavior, which follows a scaling relation with applied field and temperature, for doping (x) above the putative QCP (x= 0.14)(5). This unconventional behavior suggests that magnetic fields probe the same physics that gives rise to the anomalous low-temperature linear-in-T resistivity(4). The magnitude of the linear MR decreases as Tc decreases and goes to zero at the end of the superconducting dome (x ~0.175) above which a conventional quadratic MR is found. These results show that there is a strong correlation between the quantum critical excitations of the strange metal state and the high-Tc superconductivity.

description: An experiment was conducted to study the effect of different level of nutrients and intercropping (Pulses) on flowering behaviour of Cashew (Anacardium occidentale L.) variety VRI -2 at State Horticultural Farm, Neyveli, and Tamil Nadu. The study was revealed that the application of 100% of the recommended dose of fertilizer + 100 kg of FYM and growing of cowpea as an intercrop was observed to be best which was recorded maximum total number of flowers panicle-1 (899.35), number of hermaphrodite flowers panicle-1 (65.71 and this was on par with the treatment 75% of the recommended dose of fertilizer + 100 kg of FYM and growing of cowpea as intercrop which recorded the total number of flowers panicle-1 (897.58), number of hermaphrodite flowers panicle-1 (64.56) as compared to control. Studies conducted elsewhere in the country in the nutrient requirement of Cashew revealed the necessity of the major nutrients like Nitrogen, Phosphorus and Potassium in fairly big amount for its growth and development and also for ensuring its sustained productivity.

description: In the same way as clinical medicine, health professions education should be evidence-based rather than based on tradition and convenience. Health professions education research (HPER), an academic area that first emerged in the 1950s, is essential for identifying new and better ways to educate health professionals. Again, just as with clinical research, setting up sustainable HPER units is critical to coordinate research efforts and facilitate the production of clear and strategic HPER. In this AMEE guide we draw upon the scholarly and grey literature and our own experiences as HPER unit leaders in several different global contexts to provide practical guidance on establishing and sustaining a HPER unit. We outline the multiple elements and considerations required to set up and operationalize a successful HPER unit, from engagement of key stakeholders and documentation of milestones to the production of programmatic research and its implementation. These are considered under the areas of
  • Who do you need to partner with?  • Setting the agenda – or What will your unit be known for?  • Your most valuable resource – people!  • Operationalizing your HPER agenda  • Leading the way  We provide concrete tips on each of the above and illustrate these key steps with examples from our own experiences or the wider literature. Whether the reader is beginning, maintaining, or seeking to renew their HPER unit, we hope that the guidance we provide is as useful as it has been to us during our own research program building endeavours.   • Who do you need to partner with?   • Setting the agenda – or What will your unit be known for?   • Your most valuable resource – people!   • Operationalizing your HPER agenda   • Leading the way   We provide concrete tips on each of the above and illustrate these key steps with examples from our own experiences or the wider literature.

description: In GaAs/AlGaAs parabolic quantum wells, subbands are depopulated by a magnetic field in the well plane. A small additional perpendicular field induces Shubnikov-de-Haas (SdH) oscillations which we have used to determine the carrier density, effective mass, and lifetime, thoughout the two subband to one subband transition. The masses of carriers in the first and second subbands differ by 50% near the threshold of population of the second subband. The second subband SdH lifetime is enhanced near the threshold, even though the onset of two subband transport increases the sample resistance.

Flux Phase as a Dynamic Jahn-Teller Phase: Berryonic Matter in the Cuprates?

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: There is considerable evidence for some form of charge ordering on the hole-doped stripes in the cuprates, mainly associated with the low-temperature tetragonal phase, but with some evidence for either charge density waves or a flux phase, which is a form of dynamic charge-density wave. These three states form a pseudospin triplet, demonstrating a close connection with the E X e dynamic Jahn-Teller effect, suggesting that the cuprates constitute a form of Berryonic matter. This in turn suggests a new model for the dynamic Jahn-Teller effect as a form of flux phase. A simple model of the Cu-O bond stretching phonons allows an estimate of electron-phonon coupling for these modes, explaining why the half breathing mode softens so much more than the full oxygen breathing mode. The anomalous properties of $O^{2-}$ provide a coupling (correlated hopping) which acts to stabilize density wave phases.
