description: Software comprehension can be extremely time-consuming due to the ever-growing size of codebases. Consequently, there is an increasing need to accelerate the code comprehension process to facilitate maintenance and reduce associated costs. A crucial aspect of this process is understanding and preserving the high quality of the code dependency structure. While a variety of code structure models already exist, there is a surprising lack of models that closely represent the source code and focus on software comprehension. As a result, there are no readily available and easy-to-use tools to assist with dependency comprehension, refactoring, and quality monitoring of code. To address this gap, we propose the Semantic Code Graph (SCG), an information model that offers a detailed abstract representation of code dependencies with a close relationship to the source code. To validate the SCG model's usefulness in software comprehension, we compare it to nine other source code representation models. Additionally, we select 11 well-known and widely-used open-source projects developed in Java and Scala and perform a range of software comprehension activities on them using three different code representation models: the proposed SCG, the Call Graph (CG), and the Class Collaboration Network (CCN). We then qualitatively analyze the results to compare the performance of these models in terms of software comprehension capabilities. These activities encompass project structure comprehension, identifying critical project entities, interactive visualization of code dependencies, and uncovering code similarities through software mining. Our findings demonstrate that the SCG enhances software comprehension capabilities compared to the prevailing CCN and CG models. We believe that the work described is a step towards the next generation of tools that streamline code dependency comprehension and management.

description: Reinforcement learning has been successfully applied to the problem of tuning PID controllers in several applications. The existing methods often utilize function approximation, such as neural networks, to update the controller parameters at each time-step of the underlying process. In this work, we present a simple finite-difference approach, based on random search, to tuning linear fixed-structure controllers. For clarity and simplicity, we focus on PID controllers. Our algorithm operates on the entire closed-loop step response of the system and iteratively improves the PID gains towards a desired closed-loop response. This allows for embedding stability requirements into the reward function without any modeling procedures.

description: This study examines the relationship between agricultural technology adoption and poverty with a focus on New Rice varieties for Africa (NERICA). The NERICAs are a group of rice varieties developed by the Africa Rice Centre during the 1990s, resulting from the inter-specific crosses between the Oryza sativa high yielding rice species from Asia and the locally adapted and multiple-stress resistant Oryza glaberrima African rice species. They are believed to provide great hope for African agriculture. Introduced in Benin in 1998, there has been no published analysis on the impact of their adoption by farmers. The paper uses the counterfactual outcomes framework of modern evaluation theory to estimate the Local Average Treatment Effect (LATE) of NERICA adoption on household expenditure among 268 households from rural Benin. Results indicate that the adoption of NERICA varieties has a positive and significant impact on household expenditure. Furthermore, the impact is higher among female-headed households (161.75 FCFA/day) than male-headed households (128.34 FCFA/day). The findings suggest that there is a scope for reducing poverty through the accelerated adoption of NERICA varieties by farmers.

description: The inverse processes of photoionization and electron-ion recombination of (hnu + Ni XXVI --> Ni XXVII + e and (hnu + Ni XXVII --> Ni XXVIII + e) are studied using the unified method for the total recombination. The method subsumes both the radiative and di-electronic recombination processes and enables self-consistent sets of results for photoionization and electron-ion recombination by using the same wavefunction expansion. Photoionization cross sections (sigma_PI), recombination cross sections (sigma_{RC}), recombination collision strengths (Omega_{RC}), and recombination rate coefficients (alpha_{RC}) are obtained for ionization balance and spectral analysis of UV and X-ray lines. Level-specific photoionization cross sections and recombination rates are presented to enable accurate computation of recombination-cascade matrices for all fine structure levels n(SLJ) up to n <= 10: 98 bound fine structure levels of Ni XXVI with 0 <= l <= 9, 0 <= L <= 11, 1/2 <= J <= 17/2, and 198 levels of Ni XXVII with 0 <= l <= 9, 0 <= L <= 14, 0 <= J <= 10. Total alpha_{RC} for Ni XXVI and Ni XXVII are compared with the existing values with very good agreement. Total recombination rate coefficients for the hydrogen-like recombined ion, Ni XXVIII, are also presented. The calculations are carried out in relativistic Breit-Pauli R-matrix (BPRM) approximation with inclusion of radiation damping of resonances. With consideration of all details of the processes, the results, which include the level specific sigma_{PI} and alpha_{R} calculated for the first time, should be the most accurate for these ions.

description: Neutrinos are known to undergo flavor conversion processes among the three flavors. The fast flavor conversion (FFC) has been the central piece of flavor conversions taking place in core-collapse supernovae (CCSNe) due to its shorter timescale to the completion of flavor conversion compared to other types of flavor conversion. Although the ordinary collisions between neutrinos and matter were once thought to decohere neutrinos and thus damp flavor conversions, it was recently realized that they can also induce the flavor conversion. The linear analysis showed that the so-called collisional flavor instability or CFI occurs in the absence of FFC. In this paper, we investigate if CFI takes place in of the post-bounce core of CCSNe, using the results of spherically symmetric Boltzmann simulations of CCSNe for four progenitor models with different masses. We also provide a necessary (but not sufficient) condition of matter properties for the occurrence of CFI in optically thick and semi-transparent regions; baryon mass density ($ρ$), electron fraction ($Y_e$), and the degeneracy of electron-type neutrinos ($η_{ν_e}$) need to be $10^{10} {\rm g/cm^3} \lesssim ρ\lesssim 10^{12} {\rm g/cm^3}$, $Y_e\lesssim 0.4$, and $η_{ν_e} \lesssim 0.5$, respectively. This condition allows us to easily locate the place of possible CFI occurence without detailed stability analyses, which is useful for analyzing CFI in CCSN models phenomenologically

description: This article has presented a farmer decision making model of participation in the Conservation Reserve Program (CRP) under the current rising bio-fuel production. The decision is specified as an optimal stopping problem and farming return is assumed following stochastic process with the uncertainty of growth rate. Nonliear Kalman filter approach is used to continuously upgrade the new information and estimate the random growth rate with the minimum error. The problem is formulated as a linear complementarity problem that is solved numerically using a fully implicit finite difference method. It is found that participation in the CRP is sensitive to financial incentive, and shortening contract length is also an effective method to promote land enrollment in the CRP. These results have implications for the design and implementation of conservation programs.

description: We calculate the productivity change of the dairy and crop farms in three European countries in 1995-2004 using the Divisa index. We decompose the productivity change in the stochastic frontier framework into four components: technical efficiency change, technical change, scale change and allocative change. The average annual productivity growth of the crop farms in 1995-2004 is 1.6%, 2.8% and 3.4% respectively in Germany, the Netherlands and Sweden. The main source of the productivity growth of the German and Dutch crop farms is the technical change. The main source of the growth in the Swedish crop farms is the technical efficiency change. The average annual productivity growth of the dairy farms in Germany, the Netherlands and Sweden in 1995-2004 is 0.8%, 2.2% and 1.9% respectively. The main source of the productivity growth of the German and Swedish dairy farms is due to technical change. The main source of productivity growth of the Dutch dairy farms is technical efficiency change.

description: We show that a one dimensional disordered conductor with correlated disorder has an extended state and a Landauer resistance that is non-zero in the limit of infinite system size in contrast to the predictions of the scaling theory of Anderson localization. The delocalization transition is not related to any underlying symmetry of the model such as particle-hole symmetry. For a wire of finite length the effect manifests as a sharp transmission resonance that narrows as the length of the wire is increased. Experimental realizations and applications are discussed including the possibility of constructing a narrow band light filter.

description: Despite increasingly precise observations and sophisticated theoretical models, the discrepancy between measurements of H0 from the cosmic microwave background or from Baryon Acoustic Oscillations combined with Big-Bang Nucleosynthesis versus those from local distance ladder probes -- commonly known as the $H_0$ tension -- continues to perplex the scientific community. To address this tension, Early Dark Energy (EDE) models have been proposed as alternatives to $Λ$CDM, as they can change the observed sound horizon and the inferred Hubble constant from measurements based on this. In this paper, we investigate the use of Bayesian Model Averaging (BMA) to evaluate EDE as a solution to the H0 tension. BMA consists of assigning a prior to the model and deriving a posterior as for any other unknown parameter in a Bayesian analysis. BMA can be computationally challenging in that one must approximate the joint posterior of both model and parameters. Here we present a computational strategy for BMA that exploits existing MCMC software and combines model-specific posteriors post-hoc. In application to a comprehensive analysis of cosmological datasets, we quantify the impact of EDE on the H0 discrepancy. We find an EDE model probability of $\sim$90% whenever we include the H0 measurement from Type Ia Supernovae in the analysis, whereas the other data show a strong preference for the standard cosmological model. We finally present constraints on common parameters marginalized over both cosmological models. For reasonable priors on models with and without EDE, the H0 tension is reduced by at least 20%.

Interaction of pyridoxal phosphate with acetyl-CoA carboxylase
Creators: name: Elliott, Jason Edward
Publisher: name: University of British Columbia
Year: 2009

description: Acetyl-CoA carboxylase (ACC) catalyzes the conversion of acetyl-CoA to malonyl- CoA, the first committed step in de novo fatty acid synthesis. Two mammalian ACC isoforms exist, with many distinctive properties and differential tissue distribution. ACC isoforms exist as inactive dimers that can be allosterically activated by citrate; activation being associated with polymerization, in the case of ACC-1. Inhibition of other citrateutilizing enzymes by pyridoxal phosphate (PLP) suggested that PLP might also inhibit ACC. This thesis describes work done to assess the interaction of PLP with ACC. PLP was found to be a potent inhibitor of ACC, with an apparent IC50 of 225 u M against ACC purified from liver. The effects of PLP were seen in affinity-purified ACC, suggesting its effects are direct. PLP is effective against both ACC isoforms, but ACC-1 shows greater sensitivity to PLP than ACC-2. PLP inhibition of ACC is rapid, occurring within 1 minute of addition. Pre-treatment of ACC with citrate provided substantial protection against PLP inhibition at low inhibitor concentrations; the protection being more evident with ACC-1 than ACC-2. This suggests PLP and citrate bind to the same site on ACC. Treatment with PLP and sodium borohydride leads to irreversible ACC inhibition, confirming that PLP forms a Schiff base with ACC that can be reduced with sodium borohydride. In the absence of borohydride reduction PLP interacts reversibly with ACC. Selective labelling of ACC using [3H]-borohydride indicated that PLP reacts directly with the ACC subunits. Numerous analogs of PLP were tested for inhibitory action against ACC. From these studies it was concluded that the aldehyde and negative charges on PLP are especially important for its inhibitory action on ACC. The pyridine ring is also important, but to a lesser degree than the aldehyde or phosphate. The ability to use PLP to determine the sequence of the citrate binding site and to provide the basis for inhibitor design is discussed.
A High-Accuracy Method for the Removal of Point Sources from Maps of the Cosmic Microwave Background

description: A new method for removing point radio sources and other non-Gaussian noise is proposed as a means of improving the accuracy of estimates of the angular power spectrum of the cosmic microwave background (CMB). The main idea of the method is to reconstruct fluctuations of the CMB in places contaminated by such emission, while traditional methods simply exclude these regions from consideration, leading to the appearance of "holes" in the resulting maps. The fundamental possibility of reconstructing the CMB signal in such holes follows from the analytical properties of a function with a finite spatial spectrum (the Silk damping frequency). A two-dimensional median filter is used to localize the point radio sources. Results of simulations of the method for maps of modest size are presented. The efficiency of applying the method to reconstruct the CMB from data with limited resolution and contaminated by appreciable pixel noise is investigated. The fundamental possibility of applying the method to reconstruct the CMB distribution in the region of the Galaxy is also demonstrated.

description: The quantum Kibble-Zurek mechanism (QKZM) predicts universal dynamical behavior near the quantum phase transitions (QPTs). It is now well understood for the one-dimensional quantum matter. Higher-dimensional systems, however, remain a challenge, complicated by the fundamentally different character of the associated QPTs and their underlying conformal field theories. In this work, we take the first steps toward theoretical exploration of the QKZM in two dimensions for interacting quantum matter. We study the dynamical crossing of the QPT in the paradigmatic Ising model by a joint effort of modern state-of-the-art numerical methods, including artificial neural networks and tensor networks. As a central result, we quantify universal QKZM behavior close to the QPT. We also note that, upon traversing further into the ferromagnetic regime, deviations from the QKZM prediction appear. We explain the observed behavior by proposing an {\it extended QKZM} taking into account spectral information as well as phase ordering. Our work provides a testing platform for higher-dimensional quantum simulators.

description: AbstractAims: To assess the antioxidant and antibacterial activities of two locally available natural honey samples, and determine the total phenolic content (TPC) of the honeys.
Methods: Antibacterial activity of two local natural honey samples (citrus honey: LNH1 and mango honey: LNH2) was determined against the clinical bacterial isolates of Staphylococcus aureus, Pseudomonas aeruginosa, Salmonella enterica serovar Typhi, and Escherichia coli ATCC 25922 strain, by agar-well diffusion method. The antioxidative activity of the honey samples (LNH1 and LNH2) was determined in DPPH system, and the IC50 values were calculated. The bioactive components present in the test honey samples were assessed qualitatively, and the TPC was quantified.
Results: The honey samples showed the presence of different bioactive components (flavonoids, steroids, phenol, terpenoids and quinone); the TPCs were estimated in LNH1 and LNH2 were 195.5 μg/ml and 333 μg/ml, respectively. In DPPH system, the scavenging activities of LNH1 and LNH2 ranged 43.46–75.18% and 36.09–77. 23%, respectively, with respective IC50 values of 3.83 mg/ml and 6.75 mg/ml. The test honey samples showed antibacterial activity both against gram-positive (Staph. aureus) and gram-negative (Ps. aeruginosa and S. enterica serovar Typhi) bacterial pathogens, and against the E. coli ATCC 25922 strain.
Conclusion: The locally available natural honey may be used as rich source of antioxidant and can be used as effective antibacterial agent in order to combat the bacterial infection to humans.

description: Despite serious effort, the nature of the magnetic interactions and the role of electron-correlation effects in magnetic two-dimensional (2D) van der Waals materials remain elusive. Using CrI$_3$ as a model system, we show that the calculated electronic structure including nonlocal electron correlations yields spin excitations consistent with inelastic neutron scattering measurements. Remarkably, this approach identifies an unreported correlation-enhanced interlayer super-superexchange, which rotates the magnon Dirac lines off, and introduces a gap along, the high-symmetry $Γ$-$K$-$M$ path. This discovery provides a different perspective on the gap opening mechanism observed in CrI$_3$, which was previously associated with spin-orbit coupling through the Dzyaloshinskii-Moriya interaction or Kitaev interaction. Our observation elucidates the critical role of electron correlations on the spin ordering and spin dynamics in magnetic van der Waals materials and demonstrates the necessity of explicit treatment of electron correlations in the broad family of 2D magnetic materials.

description: Deep reinforcement learning (DRL) has seen several successful applications to process control. Common methods rely on a deep neural network structure to model the controller or process. With increasingly complicated control structures, the closed-loop stability of such methods becomes less clear. In this work, we focus on the interpretability of DRL control methods. In particular, we view linear fixed-structure controllers as shallow neural networks embedded in the actor-critic framework. PID controllers guide our development due to their simplicity and acceptance in industrial practice. We then consider input saturation, leading to a simple nonlinear control structure. In order to effectively operate within the actuator limits we then incorporate a tuning parameter for anti-windup compensation. Finally, the simplicity of the controller allows for straightforward initialization. This makes our method inherently stabilizing, both during and after training, and amenable to known operational PID gains.

description: This letter proposes a novel relaying framework, semantic-forward (SF), for cooperative communications towards the sixth-generation (6G) wireless networks. The SF relay extracts and transmits the semantic features, which reduces forwarding payload, and also improves the network robustness against intra-link errors. Based on the theoretical basis for cooperative communications with side information and the turbo principle, we design a joint source-channel coding algorithm to iteratively exchange the extrinsic information for enhancing the decoding gains at the destination. Surprisingly, simulation results indicate that even in bad channel conditions, SF relaying can still effectively improve the recovered information quality.

The existing studies focus on designing complex models, which rely on a huge amount of human-annotated data. However, the annotation of VIST is extremely costly and many topics cannot be covered in the training dataset due to the long-tail topic distribution. In this paper, we focus on enhancing the generalization ability of the VIST model by considering the few-shot setting. Inspired by the way humans tell a story, we propose a topic adaptive storyteller to model the ability of inter-topic generalization. In practice, we apply the gradient-based meta-learning algorithm on multi-modal seq2seq models to endow the model the ability to adapt quickly from topic to topic. Besides, We further propose a prototype encoding structure to model the ability of intra-topic derivation. Specifically, we encode and restore the few training story text to serve as a reference to guide the generation at inference time. Experimental results show that topic adaptation and prototype encoding structure mutually bring benefit to the few-shot model on BLEU and METEOR metric. The further case study shows that the stories generated after few-shot adaptation are more relative and expressive.

description: We present Chandra gas temperature profiles at large radii for a sample of 13 nearby, relaxed galaxy clusters and groups, which includes A133, A262, A383, A478, A907, A1413, A1795, A1991, A2029, A2390, MKW4, RXJ1159+5531, and USGC S152. The sample covers a range of average temperatures from 1 to 10 keV. The clusters are selected from the archive or observed by us to have sufficient exposures and off-center area coverage to enable accurate background subtraction and reach the temperature accuracy of better than 20-30% at least to r=0.4-0.5 r_180, and for the three best clusters, to 0.6-0.7 r_180. For all clusters, we find cool gas in the cores, outside of which the temperature reaches a peak at r =~ 0.15 r_180 and then declines to ~0.5 of its peak value at r =~ 0.5 r_180. When the profiles are scaled by the cluster average temperature (excluding cool cores) and the estimated virial radius, they show large scatter at small radii, but remarkable similarity at r>0.1-0.2 r_180 for all but one cluster (A2390). Our results are in good agreement with previous measurements from ASCA by Markevitch et al. and from Beppo-SAX by DeGrandi & Molendi. Four clusters have recent XMM-Newton temperature profiles, two of which agree with our results, and we discuss reasons for disagreement for the other two. The overall shape of temperature profiles at large radii is reproduced in recent cosmological simulations.

description: This paper introduces the basic principles and application of game theory, sets up the game model of rural construction land circulation, and analyzes the utility function results under the approval of local government of China, taking Nanhai District of Foshan City as an example. Research result shows that under the current macro-economy and system conditions, the optimal way of rural construction land circulation and expansion in rapidly industrialized area is to realize independent circulation in accordance with laws and regulations without changing the land ownership. The effective approach of regulating and controlling independent circulation is to optimize game structure and the utility functions by implementing demand management of construction land, strengthening land space control, reinforcing the construction of rural land market system, and improving profit distribution mechanism. Finally, we put forward some policy proposals on how to regulate the rural construction land circulation and expansion.

description: Sensation seeking plays a role in explaining tourists' behavior in tourism and hospitality. However, there is limited knowledge about the effects of sensation seeking on street food consumption by travelers. This study examines how sensation seeking affects tourists' intentions to consume street food by incorporating the theory of planned behavior and the moderating effect of gender. This study adopted a survey method to obtain data from 394 international tourists in three major cities of Vietnam (Hanoi, Danang, and Ho Chi Minh City). Multivariate data analysis shows that tourists' attitudes, subjective norms, and perceived behavioral control positively impact their intentions to consume street food. Moreover, sensation seeking affects attitude and perceived behavioral control, leading to intentions to consume street food. Notably, gender moderates the impact of sensation seeking on attitude and subjective norms and the effects of subjective norms and perceived behavioral control on intentions to consume street food. These findings expand the current understanding of the theory of planned behavior research in the street food context and uniquely explain the mechanism through which sensation seeking enhances street food consumption intention. They also provide valuable practical implications to Vietnamese destination marketers, government administrators, and street vendors in attracting international tourists.

description: This paper discusses the problems in determining the compensational money of arable land expropriation by Income Capitalization Method and Market Comparative Method during the process of arable land expropriation. It also introduces the value composition of arable land in China. Taking Chongqing City as an example, the irrationality of compensation standard in current arable land expropriation is analyzed. Result shows that the Income Capitalization Method is rational in determining the compensational money, but the current compensation standard should be further improved.

description: In living organisms, information is processed in interconnected symphonies of ionic currents spiking through protein ion channels. As a result of dynamically switching their conductive states, ion channels exhibit a variety of current-voltage nonlinearities and memory effects. Fueled by the promise of computing architectures entirely different from von Neumann, recent attempts to identify and harness similar phenomena in artificial nanofluidic environments focused on demonstrating analog circuit elements with memory. Here we explore aqueous ionic transport through two-dimensional (2D) membranes featuring arrays of ion-trapping crown-ether-like pores. We demonstrate that for aqueous salts featuring ions with different ion-pore binding affinities, memristive effects emerge through coupling between the time-delayed state of the system and its transport properties. We also demonstrate a nanopore array that behaves as a capacitor with a strain-tunable built-in barrier, yielding behaviors ranging from current spiking to ohmic response. By focusing on the illustrative underlying mechanisms, we demonstrate that realistically observable memory effects may be achieved in nanofluidic systems featuring crown-porous 2D membranes.

description: We present a theoretical formulation of the one-electron problem constrained on the surface of a cylindrical tubule with varying diameter. Because of the cylindrical symmetry, we may reduce the problem to a one-dimensional equation for each angular momentum quantum number $m$ along the cylindrical axis. The geometrical properties of the surface determine the electronic structures through the geometry dependent term in the equation. Magnetic fields parallel to the axis can readily be incorporated. Our formulation is applied to simple examples such as the catenoid and the sinusoidal tubules. The existence of bound states as well as the band structures, which are induced geometrically, for these surfaces are shown. To show that the electronic structures can be altered significantly by applying a magnetic field, Aharonov-Bohm effects in these examples are demonstrated.

description: Cooperative overtaking is believed to have the capability of improving road safety and traffic efficiency by means of the real-time information exchange between traffic participants, including road infrastructures, nearby vehicles and others. In this paper, we focused on the critical issues of modeling, computation, and analysis of cooperative overtaking and made it playing a key role in the road overtaking area. In detail, for the purpose of extending the awareness of the surrounding environment, the lane markings in front of ego vehicle were detected and modeled with Bezier curve using an onboard camera. While the nearby vehicle positions were obtained through the vehicle-to-vehicle communication scheme making assure of the accuracy of localization. Then, Gaussian-based conflict potential field was proposed to guarantee the overtaking safety, which can quantitatively estimate the oncoming collision danger. To support the proposed method, many experiments were conducted on the human-in-the-loop simulation platform. The results demonstrated that our proposed method achieves better performance, especially in some unpredictable nature road circumstances.

description: Many cities and towns offer to citizens a Bike-Sharing System (BSS). When a company starts the service, multiple decisions have to be taken at strategic, tactical, and operational level. When the service is in place, it is often necessary to adapt these decisions to changed conditions. In this paper, starting from the experience gained in the real-case of Bicimia in Brescia, Italy, we present a simulation framework to support decisions in the design or revision of a BSS, including the shifts of the operators, the number of vehicles and their capacity, the sizing of the stations, and the sizing of the fleet of bikes.
