description: A systematic approach to the non-Markovian quantum dynamics of open systems is given by the projection operator techniques of nonequilibrium statistical mechanics. Combining these methods with concepts from quantum information theory and from the theory of positive maps, we derive a class of correlated projection superoperators that take into account in an efficient way statistical correlations between the open system and its environment. The result is used to develop a generalization of the Lindblad theory to the regime of highly non-Markovian quantum processes in structured environments.

description: Using K2, we recently discovered a new type of periodic photometric variability while analysing the light curves of members of Upper Sco (Stauffer \etal\ 2017). The 23 exemplars of this new variability type are all mid-M dwarfs, with short rotation periods. Their phased light curves have one or more broad flux dips or multiple arcuate structures which are not explicable by photospheric spots or eclipses by solid bodies. Now, using TESS data, we have searched for this type of variability in the other major sections of Sco-Cen, Upper Centaurus-Lupus (UCL) and Lower Centaurus-Crux (LCC). We identify 28 stars with the same light curve morphologies. We find no obvious difference between the Upper Sco and the UCL/LCC representatives of this class in terms of their light curve morphologies, periods or variability amplitudes. The physical mechanism behind this variability is unknown, but as a possible clue we show that the rapidly rotating mid-M dwarfs in UCL/LCC have slightly different colors from the slowly rotating M dwarfs - they either have a blue excess (hot spots?) or a red excess (warm dust?). One of the newly identified stars (TIC242407571) has a very striking light curve morphology. At about every 0.05 in phase are features that resemble icicles, The "icicles" arise because there is a second periodic system whose main feature is a broad flux dip. Using a toy model, we show that the observed light curve morphology results only if the ratio of the two periods and the flux dip width are carefully arranged.

description: Computing free energy is a fundamental problem in statistical physics. Recently, two distinct methods have been developed and have demonstrated remarkable success: the tensor-network-based contraction method and the neural-network-based variational method. Tensor networks are accu?rate, but their application is often limited to low-dimensional systems due to the high computational complexity in high-dimensional systems. The neural network method applies to systems with general topology. However, as a variational method, it is not as accurate as tensor networks. In this work, we propose an integrated approach, tensor-network-based variational autoregressive networks (TNVAN), that leverages the strengths of both tensor networks and neural networks: combining the variational autoregressive neural network's ability to compute an upper bound on free energy and perform unbiased sampling from the variational distribution with the tensor network's power to accurately compute the partition function for small sub-systems, resulting in a robust method for precisely estimating free energy. To evaluate the proposed approach, we conducted numerical experiments on spin glass systems with various topologies, including two-dimensional lattices, fully connected graphs, and random graphs. Our numerical results demonstrate the superior accuracy of our method compared to existing approaches. In particular, it effectively handles systems with long-range interactions and leverages GPU efficiency without requiring singular value decomposition, indicating great potential in tackling statistical mechanics problems and simulating high-dimensional complex systems through both tensor networks and neural networks.

description: An instability in the presence of matter in theories of gravity which include a 1/R correction in the gravitational action has been found by Dolgov and Kawasaki. In the present paper this instability is discussed for f(R) gravity in general. We focus on the Palatini formalism of the theory and it is shown that no such instability occurs in this version of f(R) gravity. The reasons for the appearance of the instability in the metric but not in the Palatini formalism are fully investigated.

Postmodern selves and the problem of self-identity
Creators: name: Hennig, Karl H.
Publisher: name: University of British Columbia
Year: 2009

description: This research sought to operationalize some of the central psychological elements of emergent contemporary selves, herein broadly dubbed, postmodern. These elements involve both the multiplicity of the self-concept (as measured by Linville's self-sorting task) and the accounts that people employ to justify their self-identity (obtained by semi-structured interview and scored using Chandler's developmental taxonomy). Participants also responded to six measures of wellbeing and adaptiveness: perceived stress, locus of control, behavioral flexibility, self-concept confusion, self-esteem, and self-focused attention. It was hypothesized that the combination of high self-multiplicity with more dynamic, or functional, accounts of self-identity, termed multiplicitous functionalism, will contribute to well-being. Participants were 64 female and male undergraduates in the 18- to 24-year age group - a point in the lifespan when self-identity is undergoing considerable flux. Results indicated that, as expected, higher levels of self-identity were associated with greater self-multiplicity. The various measures of well-being were meaningfully correlated. The locus of control construct was used to make a number of important distinctions. For example, those low in perceived stress and those high in behavioral flexibility, self-esteem, and self-clarity reported greater internality. Consistent with the central thrust of this research, multiplicitous functionalism (high in both self-multiplicity and self-identity) was associated with overall psychological adaptiveness and well-being, as evidenced by greater behavioral flexibility and reflection, and less rumination and perceived stress. This thesis has sought to buttress the argument for a developmental consideration of selfhood, contending that recent talk of protean, polyphonic selves do suggest themselves as adaptive, particularly in a culture where instability and fragmentation seem often the case.
Multiple Emission Regions in Jets of Low Luminosity Active Galactic Nucleus in NGC 4278

description: The Large High Altitude Air Shower Observatory (LHAASO) has detected very high energy gamma rays from the LINER galaxy NGC 4278, which has a low luminosity active galactic nucleus, and symmetric mildly relativistic S-shaped twin jets detected by radio observations. Few low-luminosity active galactic nuclei are detected in gamma rays due to their faintness. Earlier, several radio-emitting components were detected in the jets of NGC 4278. We model their radio emission with synchrotron emission of ultra-relativistic electrons to estimate the strength of the magnetic field inside these components within a time-dependent framework after including the ages of the different components. We show that the synchrotron and synchrotron self-Compton emission by these components cannot explain the Swift X-ray data and the LHAASO gamma-ray data from NGC 4278. We suggest that a separate component in one of the jets is responsible for the high energy emission whose age, size, magnetic field and the spectrum of the ultra-relativistic electrons inside it have been estimated after fitting the multi-wavelength data of NGC 4278 with the sum of the spectral energy distributions from the radio components and the high energy component. We note that the radio components of NGC 4278 are larger than the high-energy component which has also been observed in several high-luminosity active galactic nuclei.

description: While a large number of adaptive Differential Evolution (DE) algorithms have been proposed, their Parameter Adaptation Methods (PAMs) are not well understood. We propose a Target function-based PAM simulation (TPAM) framework for evaluating the tracking performance of PAMs. The proposed TPAM simulation framework measures the ability of PAMs to track predefined target parameters, thus enabling quantitative analysis of the adaptive behavior of PAMs. We evaluate the tracking performance of PAMs of widely used five adaptive DEs (jDE, EPSDE, JADE, MDE, and SHADE) on the proposed TPAM, and show that TPAM can provide important insights on PAMs, e.g., why the PAM of SHADE performs better than that of JADE, and under what conditions the PAM of EPSDE fails at parameter adaptation.

description: Current air pollution control predominantly employs reactive measures like emergency factory closures and production restrictions, which may disrupt socioeconomic activities while lacking sustainability. To address this limitation, we propose proactive urban planning interventions for long-term synergistic PM2.5 and ozone (O3) control through the development of the city-level urban form regulation-aided air quality optimization model (CUFR-AQOM). The model utilizes GeoDetector to identify global drivers of air pollution, followed by hybrid stepwise regression and geographic weighted regression to establish localized mapping relationships between air quality and urban form indicators (UFIs). Subsequently, it designs regulatory pathways incorporating regulatable UFI thresholds and air quality optimization targets. Validation across 274 Chinese cities (2005–2020) showed the model’s robust predictive performance, achieving coefficients of determination (R2) of 0.88 and 0.89 for PM2.5 and O3, and root mean squared errors (RMSE) of 5.09 μg/m3 and 4.71 μg/m3 for PM2.5 and O3, respectively. Projections for the post-regulation scenario revealed a notable reduction in the number of cities exceeding secondary standards for PM2.5 (from 141 to 94) and O3 (from 46 to 31), underscoring the effectiveness of UFIs regulation in synergistic PM2.5 and O3 control. This study contributes a novel decision-making framework for air quality-friendly urban planning and provides suggestions for tailored regional regulation.
Dynamical decoupling induced renormalization of the non-Markovian dynamics

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: In this work we develop a numerical framework to investigate the renormalization of the non-Markovian dynamics of an open quantum system to which dynamical decoupling is applied. We utilize a non-Markovian master equation which is derived from the non-Markovian quantum trajectories formalism. It contains incoherent Markovian dynamics and coherent Schrödinger dynamics as its limiting cases and is capable of capture the transition between them. We have performed comprehensive simulations for the cases in which the system is either driven by the Ornstein-Uhlenbeck noise or or is described by the spin-boson model. The renormalized dynamics under bang-bang control and continuous dynamical decoupling are simulated. Our results indicate that the renormalization of the non-Markovian dynamics depends crucially on the spectral density of the environment and the envelop of the decoupling pulses. The framework developed in this work hence provides an unified approach to investigate the efficiency of realistic decoupling pulses. This work also opens a way to further optimize the decoupling via pulse shaping.

description: Bismuth perovskites ABiO$_3$ (A = Sr, Ba) host a variety of peculiar phenomena including bond-disproportionated insulating phases and high-temperature superconductivity upon hole doping. While the mechanisms underlying these phenomena are still debated, off-diagonal electron-phonon ($e$-ph) coupling originating from the modulation of the orbital overlaps has emerged as a promising candidate. Here, we employ classical Monte Carlo simulations to study a semiclassical three-orbital model with off-diagonal $e$-ph interactions. We demonstrate the existence of a (bi)polaron correlations that persists in the model at high temperatures and for hole doping away from the bond-disproportionated insulating phase. Using a spatiotemporal regression analysis between various local quantities and the lattice degrees of freedom, we also identify the similarity between heating- and doping-induced melting of a bond-disproportionated insulator at a microscopic level. Our results imply that (bi)polaron physics can be a unifying concept that helps us understand the rich bismuth perovskite phase diagram.
The role of the non-linearity in controlling the surface roughness in the one-dimensional Kardar--Parisi--Zhang growth process

description: We explore linear control of the one-dimensional non-linear Kardar--Parisi--Zhang (KPZ) equation with the goal to understand the effects the control process has on the dynamics and on the stationary state of the resulting stochastic growth kinetics. In linear control, the intrinsic non-linearity of the system is maintained at all times. In our protocol, the control is applied to only a small number $n_c$ of Fourier modes. The stationary-state roughness is obtained analytically in the small-$n_c$ regime with weak non-linear coupling wherein the controlled growth process is found to result in Edwards--Wilkinson dynamics. Furthermore, when the non-linear KPZ coupling is strong, we discern a regime where the controlled dynamics shows scaling in accordance to the KPZ universality class. We perform a detailed numerical analysis to investigate the controlled dynamics subject to weak as well as strong non-linearity. A first-order perturbation theory calculation supports the simulation results in the weak non-linear regime. For strong non-linearity, we find a temporal crossover between KPZ and dispersive growth regimes, with the crossover time scaling with the number $n_c$ of controlled Fourier modes. We observe that the height distribution is positively skewed, indicating that as a consequence of the linear control, the surface morphology displays fewer and smaller hills than in the uncontrolled growth process, and that the inherent size-dependent stationary-state roughness provides an upper limit for the roughness of the controlled system.

description: Using nonequilibrium computer simulations, we study the response of ferromagnetic nanofilaments, consisting of stabilized onedimensional chains of ferromagnetic nanoparticles, under external rotating magnetic fields. In difference with their analogous microscale and stiff counterparts, which have been actively studied in recent years, nonequilibrium properties of rather flexible nanoparticle filaments remain mostly unexplored. By progressively increasing the modeling details, we are able to evidence the qualitative impact of main interactions that can not be neglected at the nanoscale, showing that filament flexibility, thermal fluctuations and hydrodynamic interactions contribute independently to broaden the range of synchronous frequency response in this system. Furthermore, we also show the existence of a limited set of characteristic dynamic filament configurations and discuss in detail the asynchronous response, which at finite temperature becomes probabilistic.

description: Any theory that have a global spontaneously broken symmetry will imply the existence of very light neutral bosons or massless bosons (sometimes called Majorons). For most of these models we have neutrino-Majoron couplings, that appear as additional branching ratios in decays of mesons and leptons. Here we present an updated limits on the couplings between the electron, muon and tau neutrinos and Majorons. For such we analyze the possible effects of Majoron emission in both meson and lepton decays. In the latter we also include an analysis of the muon decay spectrum. Our results are $|g_{eα}|^{2}<5.5x10^{-6}$, $|g_{μα}|^{2}<4.5x10^{-5}$ and $|g_{τα}|^{2}<5.5x10^{-2}$ at 90 % C. L., where $α=e,μ,τ$.

description: Previous work has shown that artificial neural agents naturally develop surprisingly non-efficient codes. This is illustrated by the fact that in a referential game involving a speaker and a listener neural networks optimizing accurate transmission over a discrete channel, the emergent messages fail to achieve an optimal length. Furthermore, frequent messages tend to be longer than infrequent ones, a pattern contrary to the Zipf Law of Abbreviation (ZLA) observed in all natural languages. Here, we show that near-optimal and ZLA-compatible messages can emerge, but only if both the speaker and the listener are modified. We hence introduce a new communication system, "LazImpa", where the speaker is made increasingly lazy, i.e. avoids long messages, and the listener impatient, i.e.,~seeks to guess the intended content as soon as possible.

description: In the realm of IoT/CPS systems connected over mobile networks, traditional intrusion detection methods analyze network traffic across multiple devices using anomaly detection techniques to flag potential security threats. However, these methods face significant privacy challenges, particularly with deep packet inspection and network communication analysis. This type of monitoring is highly intrusive, as it involves examining the content of data packets, which can include personal and sensitive information. Such data scrutiny is often governed by stringent laws and regulations, especially in environments like smart homes where data privacy is paramount. Synthetic data offers a promising solution by mimicking real network behavior without revealing sensitive details. Generative models such as Generative Adversarial Networks (GANs) can produce synthetic data, but they often struggle to generate realistic data in specialized domains like network activity. This limitation stems from insufficient training data, which impedes the model's ability to grasp the domain's rules and constraints adequately. Moreover, the scarcity of training data exacerbates the problem of class imbalance in intrusion detection methods. To address these challenges, we propose a Privacy-Driven framework that utilizes a knowledge-infused Generative Adversarial Network for generating synthetic network activity data (KiNETGAN). This approach enhances the resilience of distributed intrusion detection while addressing privacy concerns. Our Knowledge Guided GAN produces realistic representations of network activity, validated through rigorous experimentation. We demonstrate that KiNETGAN maintains minimal accuracy loss in downstream tasks, effectively balancing data privacy and utility.

description: This thesis presents a method for business analysis: Object-Oriented Enterprise Modelling (OOEM). The purpose of enterprise modelling is to assist user to understand, capture, and communicate both structural and dynamic aspects of business activities in an organization. Based on the research by Wand and Woo in this area, this thesis derives from ontology a formal model of an object and object-oriented system. It proposes a Request Propagation Algorithm, a systematic method for finding objects and creating an enterprise model. It also discusses the use of Object Communication Diagram to model the interactions among objects and Object Detail Template to specify services, attributes and request propagation of a single object. To illustrate the way in which the method can be applied, a reasonably realistic case analysis is presented. Finally, the thesis examines the contributions of OOEM to the field of object-oriented modelling by comparing it with Coad and Yourdon OOA, Jacobson's business modelling method, and Rumbaugh's OMT.

description: The recently advanced robotics technology enables robots to assist users in their daily lives. Haptic guidance (HG) improves users' task performance through physical interaction between robots and users. It can be classified into optimal action-based HG (OAHG), which assists users with an optimal action, and user prediction-based HG (UPHG), which assists users with their next predicted action. This study aims to understand the difference between OAHG and UPHG and propose a combined HG (CombHG) that achieves optimal performance by complementing each HG type, which has important implications for HG design. We propose implementation methods for each HG type using deep learning-based approaches. A user study (n=20) in a haptic task environment indicated that UPHG induces better subjective evaluations, such as naturalness and comfort, than OAHG. In addition, the CombHG that we proposed further decreases the disagreement between the user intention and HG, without reducing the objective and subjective scores.

description: Efficient path planning is key for safe autonomous navigation over complex and unknown terrains. Lunar Zebro (LZ), a project of the Delft University of Technology, aims to deploy a compact rover, no larger than an A4 sheet of paper and weighing not more than 3 kilograms. In this work, we introduce a Robust Artificial Potential Field (RAPF) algorithm, a new path-planning algorithm for reliable local navigation solution for lunar microrovers. RAPF leverages and improves state of the art Artificial Potential Field (APF)-based methods by incorporating the position of the robot in the generation of bacteria points and considering local minima as regions to avoid. We perform both simulations and on field experiments to validate the performance of RAPF, which outperforms state-of-the-art APF-based algorithms by over 15% in reachability within a similar or shorter planning time. The improvements resulted in a 200% higher success rate and 50% lower computing time compared to the conventional APF algorithm. Near-optimal paths are computed in real-time with limited available processing power. The bacterial approach of the RAPF algorithm proves faster to execute and smaller to store than path planning algorithms used in existing planetary rovers, showcasing its potential for reliable lunar exploration with computationally constrained and energy constrained robotic systems.

description: We study a two dimensional, two-band double-exchange model for $e_g$ electrons coupled to Jahn-Teller distortions in the presence of quenched disorder using a recently developed Monte-Carlo technique. In the absence of disorder the half-filled system at low temperatures is an orbitally ordered ferromagnetic insulator with a staggered pattern of Jahn-Teller distortions. We examine the finite temperature transition to the orbitally disordered phase and uncover a qualitative difference between the intermediate and strongly coupled systems, including a thermally driven insulator to metal crossover in the former case. Long range orbital order is suppressed in the presence of disorder and the system displays a tendency towards metastable states consisting of orbitally disordered stripe-like structures enclosing orbitally ordered domains.

description: Event camera, a bio-inspired asynchronous triggered camera, offers promising prospects for fusion with frame-based cameras owing to its low latency and high dynamic range. However, calibrating stereo vision systems that incorporate both event and frame-based cameras remains a significant challenge. In this letter, we present EF-Calib, a spatiotemporal calibration framework for event- and frame-based cameras using continuous-time trajectories. A novel calibration pattern applicable to both camera types and the corresponding event recognition algorithm is proposed. Leveraging the asynchronous nature of events, a derivable piece-wise B-spline to represent camera pose continuously is introduced, enabling calibration for intrinsic parameters, extrinsic parameters, and time offset, with analytical Jacobians provided. Various experiments are carried out to evaluate the calibration performance of EF-Calib, including calibration experiments for intrinsic parameters, extrinsic parameters, and time offset. Experimental results show that EF-Calib achieves the most accurate intrinsic parameters compared to current SOTA, the close accuracy of the extrinsic parameters compared to the frame-based results, and accurate time offset estimation. EF-Calib provides a convenient and accurate toolbox for calibrating the system that fuses events and frames. The code of this paper will also be open-sourced at: https://github.com/wsakobe/EF-Calib.

description: Finite-thickness interphases between different constituents in heterogeneous materials are often replaced by a zero-thickness interface model. Commonly accepted interface models intuitively assume that the interface layer is situated exactly in the middle of its associated interphase. Furthermore, it has been reported in the literature that this assumption is necessary to guarantee the balance of angular momentum on the interface. While the interface coincides with the mid-layer of a uniform interphase, we argue that this assumption fails to sufficiently capture the behavior of graded or inhomogeneous interphases. This contribution extends the formulation of the general interface model to account for arbitrary interface positions. The issue of angular momentum balance on general interfaces is critically revisited. It is proven that the interface position does not necessarily have to coincide with the mid-layer in order to satisfy the angular momentum balance. The analysis here leads to a unique definition of the controversially discussed interface configuration. The presented general interface model is essentially based upon the weighted average operator instead of the commonly accepted classical average operator. The framework is geometrically exact and suitable for finite deformations. The significance of the interface position is demonstrated via a series of examples where the interface position is identified based on a full resolution interphase.

Specialization in Hierarchical Learning Systems

description: Joining multiple decision-makers together is a powerful way to obtain more sophisticated decision-making systems, but requires to address the questions of division of labor and specialization. We investigate in how far information constraints in hierarchies of experts not only provide a principled method for regularization but also to enforce specialization. In particular, we devise an information-theoretically motivated on-line learning rule that allows partitioning of the problem space into multiple sub-problems that can be solved by the individual experts. We demonstrate two different ways to apply our method: (i) partitioning problems based on individual data samples and (ii) based on sets of data samples representing tasks. Approach (i) equips the system with the ability to solve complex decision-making problems by finding an optimal combination of local expert decision-makers. Approach (ii) leads to decision-makers specialized in solving families of tasks, which equips the system with the ability to solve meta-learning problems. We show the broad applicability of our approach on a range of problems including classification, regression, density estimation, and reinforcement learning problems, both in the standard machine learning setup and in a meta-learning setting.
Origins of lake-stream pairs of threespine stickleback (Gasterosteus aculeatus)
Creators: name: Thompson, Claire Elizabeth
Publisher: name: University of British Columbia
Year: 2009

description: I examined lake-stream pairs of threespine stickleback {Gasterosteus aculeatus) using molecular techniques with special emphasis on the Misty Lake pair. Analysis of the lake-stream pair in Misty Lake (Keogh River system, northern Vancouver Island) revealed that the forms represent two separate gene pools as opposed to a single gene pool with some complex polymorphism. There were significant differences between the forms in the frequencies of both mitochondrial restriction fragment length polymorphism (RFLP) haplotypes and nuclear sequence types (the D3 region of 28S rRNA). As far as we know, lake-stream pairs only occur in two other drainages. I used the mitochondrial RFLP data to distinguish between two hypotheses that attempt to account for the distribution and origins of the pairs. The first hypothesis postulates a single origin of the pairs followed by dispersal. This hypothesis assumes that initial divergence of forms is allopatric subsequently followed by secondary contact. The second hypothesis postulates independent parallel evolution in at least two of the three drainages where lake-stream pairs occur. Under this hypothesis, divergence of forms could have been either allopatric or parapatric. The mitochondrial RFLP data supports the parallel evolution hypothesis; furthermore, divergence of at least the Misty Lake pair was allopatric. Lastly, unrooted neighbor-joining trees based on the mitochondrial RFLP haplotypes indicate the presence of two very divergent lineages; a Northern lineage and a Southern lineage. Other studies have identified this split, but they have never observed the Northern lineage in populations as far south as Vancouver Island.
Trivial, Critical and Near-critical Scaling Limits of Two-dimensional Percolation

description: It is natural to expect that there are only three possible types of scaling limits for the collection of all percolation interfaces in the plane: (1) a trivial one, consisting of no curves at all, (2) a critical one, in which all points of the plane are surrounded by arbitrarily large loops and every deterministic point is almost surely surrounded by a countably infinite family of nested loops with radii going to zero, and (3) an intermediate one, in which every deterministic point of the plane is almost surely surrounded by a largest loop and by a countably infinite family of nested loops with radii going to zero. We show how one can prove this using elementary arguments, with the help of known scaling relations for percolation. The trivial limit corresponds to subcritical and supercritical percolation, as well as to the case when the density p approaches the critical probability, p_c, sufficiently slowly as the lattice spacing is sent to zero. The second type corresponds to critical percolation and to a faster approach of p to p_c. The third, or near-critical, type of limit corresponds to an intermediate speed of approach of p to p_c. The fact that in the near-critical case a deterministic point is a.s. surrounded by a largest loop demonstrates the persistence of a macroscopic correlation length in the scaling limit and the absence of scale invariance.

description: Barsbold (1981) erected Ingenia yanshini Barsbold, 1981 for a nearly complete oviraptorid skeleton from the Upper Cretaceous (Campanian-Maastrichtian) Barun Goyot Formation in Ömnögov, southern Mongolia. Moreover, he erected a subfamily-level clade Ingeniinae Barsbold, 1981 to distinguish Ingenia yanshini from other oviraptorids such as Oviraptor philoceratops Osborn, 1924 (Barsbold, 1981). When Barsbold first erected the subfamily, he considered this subfamily as monotypic (Barsbold, 1981) but now this subfamily comprisesmultiple taxa such as Machairasaurus leptonychus Longrich, Currie, and Dong, 2010 and Heyuannia huangi Lü, 2002.
 However, the genus name Ingenia is a junior homonym of the tripyloidid nematode genus Ingenia Gerlach, 1957 and according to the Article 23.1 of the International Code of Zoological Nomenclature (ICZN, 1999), Gerlach’s 1957 name has priority. Therefore, the usage of the subfamily name Ingeniinae is problematic as it is based on a junior homonym.
 Paul (1988) suggested a new combination Oviraptor yanshini for “ Ingenia ” yanshini but this classification has not been supported by any subsequent authors (Easter, 2013). Easter (2013) proposed a new genus name Ajancingenia Easter, 2013 for “ Ingenia ” yanshini, but subsequent phylogenetic analyses have found “ Ingenia ” yanshini and Heyuannia huangi as sister taxa (e.g., Lamanna et al., 2014; Funston and Currie, 2016; Lü et al., 2016; Funston et al., 2018). Therefore, most recent studies have considered Ajancingenia as junior synonym of Heyuannia and used new combination Heyuannia yanshini for “ Ingenia ” yanshini (e.g., Funston et al., 2018; Herne et al., 2018). Thus, Heyuannia is the proper synonym available as a replacement name of the junior homonym. Therefore, the author proposes a new replacement subfamily name Heyuanninae clade. nov. (from Heyuannia and –inae) for “Ingeniinae”.
 Osmolska et al. (2004) defined “Ingeniinae” as Conchoraptor gracilis, Ingenia yanshini, their most recent common ancestor, and all descendants. Here the author revises this definition for Heyuanninae, using Heyuannia huangi as the specifier. Heyuanninae is a node-based subfamily-level clade that can be defined as the least inclusive clade containing Heyuannia huangi and Conchoraptor gracilis.
