description: The non-structural carbohydrate (NSC) stored in rice stems (culm plus leaf sheaths) at pre-heading stage is one of the major carbon sources for grain filling. In this study, we conducted field experiments in 2018 and 2019 using two varieties, Momiroman (japonica-dominant) and Teqing (indica), which have different accumulation and remobilization patterns of NSC in the stems. We analyzed NSC dynamics of each of the five nodal segments of internodes and leaf sheaths at pre- and post-heading stages. The dynamics of NSC at pre- and post-heading stages differed among segments. The lower segments of internodes and leaf sheaths accumulated more NSC at pre-heading stage compared to the upper segments in both varieties. The lower internodes in Teqing were morphologically larger than in Momiroman and would be able to store more NSC. However, the upper parts of the stems required biomass for development and formation at the stage of NSC accumulation in stems. Momiroman had longer upper internodes and leaf sheaths and required more biomass than Teqing. The NSC remobilization was later in the upper than the lower internodes for both varieties, which led to the delay of NSC remobilization in the entire culm after heading. These results indicated that ideal morphology of stems, to maximize the potential contribution of stem NSC as the carbon source for grain filling, is large lower internodes and short upper internodes and leaf sheaths.

description: We present a model for simulating normal forces arising during a grind- ing process in cement for single diamond grinding. Assuming the diamond to have the shape of a pyramid, a very fast calculation of force and removed volume can be achieved. The basic approach is the simulation of the scratch track. Its triangle profile is determined by the shape of the diamond. The approximation of the scratch track is realized by stringing together polyhedra. Their sizes depend on both the actual cutting depth and an error implicitly describing the material brittleness. Each scratch track part can be subdivided into three three-dimensional simplices for a straightforward calculation of the removed volume. Since the scratched min- eral subsoil is generally inhomogeneous, the forces at different positions of the workpiece are expected to vary. This heterogeneous nature is considered by sam- pling from a Gaussian random field. To achieve a realistic outcome the model parameters are adjusted applying model based optimization methods. A noisy Kriging model is chosen as surrogate to approximate the deviation between modelled and observed forces. This devia- tion is minimized and the results of the modelled forces and the actual forces from conducted experiments are rather similar.

description: Non-linear cosmic structures contain valuable information on the expansion history of the background space-time, the nature of dark matter, and the gravitational interaction. The recently developed kinetic field theory of cosmic structure formation (KFT) allows to accurately calculate the non-linear power spectrum of cosmic density fluctuations up to wave numbers of $k\lesssim10\,h\,\mathrm{Mpc}^{-1}$ at redshift zero. Cosmology and gravity enter this calculation via two functions, viz. the background expansion function and possibly a time-dependent modification of the gravitational coupling strength. The success of the cosmological standard model based on general relativity suggests that cosmological models in generalized theories of gravity should have observable effects differing only weakly from those in standard cosmology. Based on this assumption, we derive the functional, first-order Taylor expansion of the non-linear power spectrum of cosmic density fluctuations obtained from the mean-field approximation in KFT in terms of the expansion function and the gravitational coupling strength. This allows us to study non-linear power spectra expected in large classes of generalized gravity theories. To give one example, we apply our formalism to generalized Proca theories.

description: The QCD axion with $f_a$ at an intermediate scale, 10**9-10**12 GeV, seems in conflict with the gravity spoil of global symmetries and may face the axionic domain wall problem. We point out that the string compactifications with an anomalous U(1) gauge symmetry, allowing desirable chiral matter spectra, circumvent these two problems simultaneously.

description: The strange metallic regime across a number of high-temperature superconducting materials presents numerous challenges to the classic theory of Fermi liquid metals. Recent measurements of the dynamical charge response of strange metals, including optimally doped cuprates, have revealed a broad, featureless continuum of excitations, extending over much of the Brillouin zone. The collective density oscillations of this strange metal decay into the continuum in a manner that is at odds with the expectations of Fermi liquid theory. Inspired by these observations, we investigate the phenomenology of bosonic collective modes and the particle-hole excitations in a class of strange metals by making an analogy to the phonons of classical lattices falling apart across an unconventional jamming-like transition associated with the onset of rigidity. By making comparisons to the experimentally measured dynamical response functions, we reproduce many of the qualitative features using the above framework. We conjecture that the dynamics of electronic charge density over an intermediate range of energy scales in a class of strongly correlated metals can be at the brink of a jamming-like transition.

description: Ipomoea trifida, the closest relative of sweetpotato, does not generally form storage roots, but some lines develop thick roots similar to the storage roots of the sweetpotato. Revealing the molecular mechanism of thick root development in I. trifida would help us understand the evolution of storage roots in the sweetpotato. In this study, we conducted a mapping method for quantitative trait loci (QTLs) known as QTL-seq, which is a kind of next-generation sequencing-based bulk segregant analysis. We performed QTL-seq using a backcross population (BC1F1) derived from two I. trifida lines: Mx23Hm, which does not show root-thickening; and 0431-1, which produces thick roots. The aim was to identify the QTL region involved in thick root development. As a result, a major QTL for root thickness (qRT1) was detected in the 2.94–8.71 Mb region of chr06 of Itr_r2.2, in both pot and field experiments. Six DNA markers were designed for qRT1 using InDels on chr06. Genotyping each BC1F1 individual based on these DNA markers agreed well with the SNP-Index of QTL-seq. Moreover, most individuals with 0431-1-type alleles of qRT1 developed thicker roots than individuals without 0431-1-type alleles of qRT1 in the BC2F2 population. The results of this study implied that qRT1 was an important QTL for regulating root thickness in I. trifida.

description: In [1], a most general higher curvature non-local gravity action was derived that admits a particular $R^2$-like inflationary solution predicting the spectral index of primordial scalar perturbations $n_s(N)\approx 1-\frac{2}{N}$, where $N$ is the number of e-folds before the end of inflation, $N\gg 1$, any value of the tensor-to-scalar ratio $r(N)<0.036$ and the tensor tilt $n_t(N)$ violating the $r= -8n_t$ condition. In this paper, we compute scalar primordial non-Gaussianities (PNGs) in this theory and effectively demonstrate that higher curvature non-local terms lead to reduced bispectrum $f_{\rm NL}\left( k_1,\,k_2,\,k_3 \right)$ mimicking several classes of scalar field models of inflation known in the literature. We obtain $\vert f_{\rm NL}\vert \sim O(1-10)$ in the equilateral, orthogonal, and squeezed limits and the running of these PNGs measured by the quantity $\vert\frac{d\ln f_{\rm NL}}{d\ln k}\vert\lesssim 1$. Such PNGs are sufficiently large to be measurable by future CMB and Large Scale Structure observations, thus providing a possibility to probe the nature of quantum gravity. Furthermore, we demonstrate that the $R^2$-like inflation in non-local modification of gravity brings non-trivial predictions which go beyond the current status of effective field theories (EFTs) of single field, quasi-single field and multiple field inflation. A distinguishable feature of non-local $R^2$-like inflation compared to local EFTs is that we can have running of PNGs at least an order of magnitude higher. In summary, through our generalized non-local $R^2$-like inflation, we obtain a robust geometric framework of inflation that can explain any detection of observable quantities related to scalar PNGs.

description: The integration of QR codes in seafood packaging has revolutionized consumer engagement by providing direct access to detailed product information. These smart labels enhance transparency, traceability, and educational value, enabling consumers to make informed purchasing decisions. Studies show that enriched content availability through QR codes increases consumer confidence and purchase intentions. QR codes also serve as effective tools for communicating product traceability in agri-food sectors, offering real-time insights into farming practices, sustainability measures, and quality assurance. Additionally, QR codes enable interactive experiences such as accessing cooking recipes and personalized offers, fostering stronger connections between consumers and producers. This paper explores the multifaceted applications and benefits of QR codes in food packaging, emphasizing their role in enhancing accessibility, consumer trust, and educational outreach.
De-Entanglement: A Framework towards building Ubiquitous speech technologies

Subjects: subject: 80107 Natural Language Processing

description: Speech driven devices and interfaces like Apple Home pod, Google Home, Amazon Echo are increasingly becoming ubiquitous and have tremendous potential to affect our daily lives. However, deep learning models underlying these applications have yet unaddressed challenges like scalability, explainability and concerns like privacy and security. In my dissertation I propose a framework called De-Entanglement that has linguistic concepts as first class objects. De-Entanglement attempts to build speech technology using two core concepts referred to as content and style. Specifically, content encompasses acoustic phonetic information while style encompasses paralinguistic information from the raw audio. In my dissertation I provide experiments that show how De-Entanglement can address three challenges in a holistic fashion: (1) Scalability: How to build speech technologies for new languages / language phenomena such as code switching? I demonstrate how De-Entanglement helps build more natural Text to Speech (TTS) voices. This part of the work has been deployed in the form of Android application in 13 Indian languages and has been assisting people since 2016. (2) Flexibility: How to build models that can be manipulated to accomplish a variety of functionality such as finetuning, meta learning, augmentation and self training? I present experiments in two types of models. In the context of generative models, I present an approach to show that De-Entanglement allows explicit global and local control of synthetic voices. In the context of discriminative models, I present approaches that leverage style information to detect para-linguistic events from a speech utterance. (3) Explainability: How to build technology that is reasonable to the stakeholders? I posit that explainable speech technologies should be characterized by two properties: (a) Reasonable Understanding of internal mechanisms in the model and (b) Demonstrable Utility of the model for downstream applications. Using language identification and intent recognition from acoustics as the target applications, I demonstrate (a) how suitable priors can be incorporated into a model and (b) how such an approach leads to strong performance in low and under resourced scenarios. Since these linguistic constructs(concepts) are shared across different tasks within and beyond speech processing, the solutions designed using De-Entanglement hold promise to be applicable across different tasks. I present experiments to this end in both speech processing as well as broader Natural Language Processing.
Prague and the Czech Republic: how Europe's most "magical" region gained its reputation and why it may cause more harm than good
Creators: name: Smith, Auralee
Publisher: name: No Publisher Supplied
Year: 2023

description: The city of Prague and the country of the Czech Republic (Czechia) have a profoundly meaningful history, showing a timeline of heroisms, tribulations, and nationalistic accomplishments. Czechs take great pride in their country and its history that demonstrates more than anything, incredible resiliency through centuries of subjugation to foreign governments and institutions. However, a reputation for magic and mystery particularly concentrated in Prague and the Bohemian region of the country is well-known throughout the world. Why this reputation came to be and how it continues to impact the Czech people are the questions at hand. Research methods included an in-depth analysis of a multitude of articles, journals, and books. In addition, one month was spent in Prague studying, exploring popular sites (e.g. astronomical clock, alchemy laboratories) as well as experiencing the culture and learning from the people. Prague and Czechia’s reputation for having deeper cultural ties to magic than other European countries has been largely invented by outside influences, ranging from foreign leaders, such as Holy Roman Emperor Rudolf II, to modern tourists. For a country continually infiltrated by foreign rulers and agendas over the centuries, the focus on a “magic Prague” has helped to overshadow the longstanding attempts of Czechs to uphold a proud national identity.

description: We study constructing an algebraic curve from a Riemann surface given via a translation surface, which is a collection of finitely many polygons in the plane with sides identified by translation. We use the theory of discrete Riemann surfaces to give an algorithm for approximating the Jacobian variety of a translation surface whose polygon can be decomposed into squares. We first implement the algorithm in the case of $L$ shaped polygons where the algebraic curve is already known. The algorithm is also implemented in any genus for specific examples of Jenkins-Strebel representatives, a dense family of translation surfaces that, until now, lived squarely on the analytic side of the transcendental divide between Riemann surfaces and algebraic curves. Using Riemann theta functions, we give numerical experiments and resulting conjectures up to genus 5.

description: We study the problem of estimating a large, low-rank matrix corrupted by additive noise of unknown covariance, assuming one has access to additional side information in the form of noise-only measurements. We study the Whiten-Shrink-reColor (WSC) workflow, where a "noise covariance whitening" transformation is applied to the observations, followed by appropriate singular value shrinkage and a "noise covariance re-coloring" transformation. We show that under the mean square error loss, a unique, asymptotically optimal shrinkage nonlinearity exists for the WSC denoising workflow, and calculate it in closed form. To this end, we calculate the asymptotic eigenvector rotation of the random spiked F-matrix ensemble, a result which may be of independent interest. With sufficiently many pure-noise measurements, our optimally-tuned WSC denoising workflow outperforms, in mean square error, matrix denoising algorithms based on optimal singular value shrinkage which do not make similar use of noise-only side information; numerical experiments show that our procedure's relative performance is particularly strong in challenging statistical settings with high dimensionality and large degree of heteroscedasticity.
Identifying and addressing diaper need by utilizing an assessment during pediatric primary care visits
Creators: name: Patel, Sonia
Publisher: name: No Publisher Supplied
Year: 2023

description: Purpose of Project: This project aimed to determine the feasibility of administering a diaper need assessment during routine health supervision appointments Methodology: This project included a sample of English-speaking adult parents, and guardians with children under the age of four who wore diapers. During in-person health supervision visits, each participant answered a survey indicating if they were able to buy enough diapers for all month by selecting yes or no. Education on local resources was provided to all patients regardless of their survey answers. Any participant that answered “no” was identified as having a positive diaper need. Those who screened positive received a telephone questionnaire asking if they had utilized the local diaper bank resources provided. Results: The sample included 99 participants, seven of whom screened positive for diaper need and received follow-up questionnaire phone calls. Four participants who screened positive for diaper need, reported use of the local diaper banks, calling them “helpful” and stating, “they did not know about diaper banks.” Two responded they had not used the local resources, citing “no time” and “no transportation.” One participant was lost to follow-up. Implications for Practice: The findings from this project determined that it is possible to identify diaper need at primary care health supervision visits. It further demonstrated that education increases resource utilization. This project suggests that assessing diaper need can be completed efficiently and quickly. With the hopeful success of this project, other local practices would be able to utilize this diaper need assessment to identify and provide resources on diaper need.

description: Weakly Schreier split extensions are a reasonably large, yet well-understood class of monoid extensions, which generalise some aspects of split extensions of groups. This short note provides a way to define and study similar classes of split extensions in general algebraic structures (parameterised by a term $θ$). These generalise weakly Schreier extensions of monoids, as well as general extensions of semi-abelian varieties (using the $θ$ appearing in their syntactical characterisation). Restricting again to the case of monoids, a different choice of $θ$ leads to a new class of monoid extensions, more general than the weakly Schreier split extensions.

description: We study the anomalous Hall effect in a disordered Weyl semimetal. While the intrinsic contribution is expressed solely in terms of Berry curvature, the extrinsic contribution is given by a combination of the skew scattering and side jump terms. For the model of small size impurities, we are able to express the skew scattering contribution in terms of scattering phase shifts. We identify the regime in which the skew scattering contribution dominates the side-jump contribution: the impurities are either strong or resonant, and at dilute concentration. In this regime, the Hall resistivity $ρ_{xy}$ is expressed in terms of two scattering phases, analogous to the s-wave scattering phase in a non-topological metal. We compute the dependence of $ρ_{xy}$ on the chemical potential, and show that $ρ_{xy}$ scales with temperature as $T^2$ in low temperatures and as $T^{3/2}$ in the high temperature limit.

description: Baryonic Acoustic Oscillations (BAOs) studies based on the clustering of voids and matter tracers provide important constraints on cosmological parameters related to the expansion of the Universe. However, modelling the void exclusion effect is an important challenge for fully exploiting the potential of this kind of analyses. We thus develop two numerical methods to describe the clustering of cosmic voids. Neither model requires additional cosmological information beyond that assumed within the galaxy de-wiggled model. The models consist in power spectra whose performance we assess in comparison to a parabolic model on Patchy cubic and light-cone mocks. Moreover, we test their robustness against systematic effects and the reconstruction technique. The void model power spectra and the parabolic model with a fixed parameter provide strongly correlated values for the Alcock-Paczynski ($α$) parameter, for boxes and light-cones likewise. The resulting $α$ values -- for all three models -- are unbiased and their uncertainties are correctly estimated. However, the numerical models show less variation with the fitting range compared to the parabolic one. The Bayesian evidence suggests that the numerical techniques are often favoured compared to the parabolic model. Moreover, the void model power spectra computed on boxes can describe the void clustering from light-cones as well as from boxes. The same void model power spectra can be used for the study of pre- and post-reconstructed data-sets. Lastly, the two numerical techniques are resilient against the studied systematic effects. Consequently, using either of the two new void models, one can more robustly measure cosmological parameters.

description: Interactive programming environments are powerful tools for promoting innovative network thinking, teaching science of complexity, and exploring emergent phenomena. This paper reports on our recent development of the deterministic random walk model in NetLogo, a leading platform for computational thinking, eco-system thinking, and multi-agent cross-platform programming environment. The deterministic random walk is foundational to modeling dynamical processes on complex networks. Inspired by the temporal visualizations offered in NetLogo, we investigated the relationship between network topology and diffusion saturation time for the deterministic random walk model. Our analysis uncovers that in Erdős-Rényi graphs, the saturation time exhibits an asymmetric pattern with a considerable probability of occurrence. This behavior occurs when the hubs, defined as nodes with relatively higher number of connections, emerge in Erdős-Rényi graphs. Yet, our analysis yields that the hubs in Barabási-Albert model stabilize the the convergence time of the deterministic random walk model. These findings strongly suggest that depending on the dynamical process running on complex networks, complementing characteristics other than the degree need to be taken into account for considering a node as a hub. We have made our development open-source, available to the public at no cost at https://github.com/bravandi/NetLogo-Dynamical-Processes.

description: The filtration of air and other fluids is a widely used mechanic used in a variety of applications. Air filtration is especially important when trying to create livable and clean environments. The most common method of filtering air is using fibrous filters. Commonly, a non-woven mat of fibers is used for filtering air. When using this kind of fibrous mat, it was common to assume the efficiency of the mat to be based on the sum of the individual efficiencies of each fiber, independent of the fibers around it. This kind of assumption is not always accurate, as studies have shown some ordered arrangements of fibers have higher total efficiencies than the sum of the efficiencies of the same quantity of individual fibers. Recently, some studies have investigated 2-fiber systems and found an increase in collection efficiency of the system for specific arrangements. This study further investigates how the relative arrangement of a 2-collector system impacts the collection efficiency of the collectors in that system. The fibers in this study are approximated as circular cylinders. An adapted method is provided to analyze particle collection efficiency for close cylinders in potential flow. This study investigates a variety of staggered cylinder arrangements and briefly covers some tandem and adjacent arrangements as well. The results of the study suggest that the collection efficiency of a close 2-cylinder system depends on both the relative offset of the cylinders and the streamwise separation between the cylinders. This study concludes that the tandem arrangement negatively impacts collection efficiency, the adjacent arrangement neutrally impacts collection efficiency, and the staggered arrangements positively impacts collection efficiency for a specific range of offset and separation values. The adjacent arrangements did not increase the collection efficiency of the system but did demonstrate a shift in collection. Where different particles would be collected by either of the cylinders in this 2-cylinder system compared to an isolated cylinder in the same location. This study also concludes that for a specific range of cylinder arrangements in a staggered configuration, the collection efficiency of the downstream cylinder can be significantly increased.

description: $γ$-ray observations of the Cygnus Cocoon, an extended source surrounding the Cygnus X star-forming region, suggest the presence of a cosmic ray accelerator reaching energies up to a few PeV. The very-high-energy (VHE; 0.1-100~TeV) $γ$-ray emission may be explained by the interaction of cosmic-ray hadrons with matter inside the Cocoon, but an origin of inverse Compton radiation by relativistic electrons cannot be ruled out. Inverse Compton $γ$-rays at VHE are accompanied by synchrotron radiation peaked in X-rays. Hence, X-ray observations may probe the electron population and magnetic field of the source. We observed eleven fields in or near the Cygnus Cocoon with the Neil Gehrels Swift Observatory's X-Ray Telescope (Swift-XRT) totaling 110 ksec. We fit the fields to a Galactic and extra-galactic background model and performed a log-likelihood ratio test for an additional diffuse component. We found no significant additional emission and established upper limits in each field. By assuming that the X-ray intensity traces the TeV intensity and follows an $dN/dE\propto E^{-2.5}$ spectrum, we obtained a 90\% upper limit of $F_X < 8.7\times 10^{-11}\rm~erg\,cm^{-2}\,s^{-1}$ or $< 5.2\times 10^{-11}\rm~erg\,cm^{-2}\,s^{-1}$ on the X-ray flux of the entire Cygnus Cocoon between 2 and 10 keV depending on the choice of hydrogen column density model. This suggests that no more than one quarter of the $γ$-ray flux at 1 TeV is produced by inverse Compton scattering, when assuming an equipartition magnetic field of $\sim 20\,μ$G.

description: This thesis posits the existence of invariant high-level musical concepts that persist regardless of changes in sonic qualities, akin to the symbolic domain where essence endures despite varying interpretations through different performances, instruments, and styles, among many other, almost countless variables.
 In collaboration with Epidemic Sound AB and the Music Technology Group (MTG) at Universitat Pompeu Fabra (UPF), we used self-supervised contrastive learning to uncover the underlying structure of Western tonal music by learning deep audio features for music boundary detection. We applied deep convolutional neural net-works with triplet loss function to identify abstract and semantic high-level musical elements without relying on their sonic qualities. This way, we replaced traditional acoustic features with deep audio embeddings, paving the way for sound-agnostic and content-sensitive music representation for downstream track segmentation tasks.
 Our cognitively-based approach for learning embeddings focuses on using full-resolution data and preserving high-level musical information which unfolds in the time do-main. A key component in our methodology is triplet networks, which effectively understand and preserve the nuanced relationships within musical data. Drawing upon our domain expertise, we developed robust transformations to encode heuristic musical concepts that should remain constant. This novel approach combines music and machine learning intending to enhance machine listening models’ efficacy.
 Preliminary results suggest that, while not outperforming state-of-the-art, our musically-informed technique has significant potential for boundary detection tasks. Most likely, so does for nearly all downstream sound-agnostic and content-sensitive tasks constrained by data scarcity, as it is possible to achieve competitive performance to traditional handcrafted signal processing methods by learning only from unlabeled audio files.
 The question remains if such general-purpose audio representation can mimic human hearing.

Search for doubly charged Higgs boson production in multi-lepton final states using 139 fb$^{-1}$ of proton-proton collisions at $\sqrt{s}$ = 13 TeV with the ATLAS detector

description: A search for pair production of doubly charged Higgs bosons ($H^{\pm \pm}$), each decaying into a pair of prompt, isolated, highly energetic leptons with the same electric charge, is presented. The search uses a proton-proton collision data sample at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity of 139 fb$^{-1}$ recorded by the ATLAS detector during Run 2 of the Large Hadron Collider. This analysis focuses on same-charge leptonic decays, $H^{\pm \pm} \rightarrow \ell^{\pm} \ell^{\prime \pm}$ where $\ell, \ell^\prime=e, μ, τ$, in two-, three-, and four-lepton channels, but only considers final states which include electrons or muons. No evidence of a signal is observed. Corresponding limits on the production cross-section and consequently a lower limit on $m(H^{\pm \pm})$ are derived at 95% confidence level. Assuming that the branching ratios to each of the possible leptonic final states are equal, $\mathcal{B}(H^{\pm \pm} \rightarrow e^\pm e^\pm) = \mathcal{B}(H^{\pm \pm} \rightarrow e^\pm μ^\pm) = \mathcal{B}(H^{\pm \pm} \rightarrow μ^\pm μ^\pm) = \mathcal{B}(H^{\pm \pm} \rightarrow e^\pm τ^\pm) = \mathcal{B}(H^{\pm \pm} \rightarrow μ^\pm τ^\pm) = \mathcal{B}(H^{\pm \pm} \rightarrow τ^\pm τ^\pm) = 1/6$, the observed lower limit on the mass of a doubly charged Higgs boson is 1080 GeV within the left-right symmetric type-II seesaw model, which is an improvement over previous limits. Additionally, a lower limit of $m(H^{\pm \pm})$ = 900 GeV is obtained in the context of the Zee-Babu neutrino mass model.

description: In this study, we focus on brain tumor sequence registration between pre-operative and follow-up Magnetic Resonance Imaging (MRI) scans of brain glioma patients, in the context of Brain Tumor Sequence Registration challenge (BraTS-Reg 2022). Brain tumor registration is a fundamental requirement in brain image analysis for quantifying tumor changes. This is a challenging task due to large deformations and missing correspondences between pre-operative and follow-up scans. For this task, we adopt our recently proposed Non-Iterative Coarse-to-finE registration Networks (NICE-Net) - a deep learning-based method for coarse-to-fine registering images with large deformations. To overcome missing correspondences, we extend the NICE-Net by introducing dual deep supervision, where a deep self-supervised loss based on image similarity and a deep weakly-supervised loss based on manually annotated landmarks are deeply embedded into the NICE-Net. At the BraTS-Reg 2022, our method achieved a competitive result on the validation set (mean absolute error: 3.387) and placed 4th in the final testing phase (Score: 0.3544).
