description: [transcription] A Montpellier le 16 janvier 1780

J'ai l'honneur de vous envoyer ci-joint, Monsieur, mon respectable confrère, deux exemplaires du cinquième et dernier volume de mon histoire minéralogique de la Province du Languedoc, l'un pour vous, et l'autre pour votre académie à qui je vous supplie de le présenter de ma part comme un tribut de mon respect pour elle.

Recevez le vôtre comme une faible marque de mon respectueux et inviolable attachement pour vous. Je comptais avoir le plaisir de vous aller embrasser à Nîmes mais des affaires m'obligent de m'en retourner par Sommières. Je recevrais avec bien de la satisfaction des nouvelles de votre santé à Villefort en Cévennes où je vais me rendre.

Vous ne sauriez me procurer un service plus sensible que celui de persuader M. Delaplane votre parent que ni moi, ni mon fils n'avons absolument aucune part au procès que la Compagnie des Mines de Villefort vient de lui intenter. J'ai fait mon possible pour le lui éviter, et de vous à moi il aura du chagrin pour un objet dont il n'est pas en état de profiter parce que 1° cet objet seul n'est pas en état de se soutenir et que ce serait se ruiner que de l'entreprendre seul, et que d'un autre côté Mr votre parent n'est pas en état d'en faire la dépense. Cela me chagrine et je vous aurai une vraie obligation de le prévenir sur ma façon de penser. J'ai l'honneur d'être avec toute la considération et l'attachement possibles,

Monsieur

Votre humble et très obéissant serviteur,

De Genssane

description: Upcoming widefield surveys, such as the Rubin Observatory's Legacy Survey of Space and Time (LSST), will monitor thousands of strongly lensed quasars over a 10 yr period. Many of these monitored quasars will undergo high-magnification events (HMEs) through microlensing, as the accretion disk crosses a caustic, places of infinite magnification. Microlensing allows us to map the inner regions of the accretion disk as it crosses a caustic, even at large cosmological distances. The observational cadences of LSST are not ideal for probing the inner regions of the accretion disk, so there is a need to predict HMEs as early as possible, to trigger high-cadence multiband or spectroscopic follow-up observations. Here, we simulate a diverse and realistic sample of 10 yr quasar microlensing light curves to train a recurrent neural network to predict HMEs before they occur, by classifying the locations of the peaks at each time step. This is the first deep-learning approach for predicting HMEs. We give estimates of how well we expect to predict HME peaks during LSST and benchmark how our metrics change with different cadence strategies. With LSST-like observations, we can predict approximately 55% of HME peaks, corresponding to tens to hundreds per year and a false-positive rate of around 20% compared to the total number of HMEs. Our network can be continuously applied throughout the LSST survey, providing crucial alerts for optimizing follow-up resources.

description: We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the Gemini Planet Imager Exoplanet Survey campaign. Images of HD 984 B were obtained in the J (1.12--1.3 micron) and H (1.50--1.80 micron) bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 AU (70 year) orbit with a 68% confidence interval between 14 and 28 AU, an eccentricity of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119 degrees with a 68% confidence interval between 114 degrees and 125 degrees. To address considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare to known spectral types using field brown dwarf and low-mass star spectra and find a best fit match of a field gravity M6.5+/-1.5 spectral type with a corresponding temperature of 2730+120 K. Photometry of the companion yields a luminosity of log(L_bol/L_sun) = -2.88+/-0.07 dex, using DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34+/-1 to 95+/-4 M_Jup. These results are consistent with previous measurements of the object.

The stickiness phenomena of nonlocal minimal surfaces: new results and a comparison with the classical case
Creators: name: Bucur, Claudia
Publisher: name: Bruno Pini Mathematical Analysis Seminar
Year: 2019
Subjects: subject: Minimal surfaces; nonlocal; stickiness; area; fractional; perimeter
subject: 49Q05; 47G20

description: We discuss in this note the stickiness phenomena for nonlocal minimal surfaces. Classical minimal surfaces in convex domains do not stick to the boundary of the domain, hence examples of stickiness can be obtained only by removing the assumption of convexity. On the other hand, in the nonlocal framework, stickiness is ''generic''. We provide various examples from the literature, and focus on the case of complete stickiness in highly nonlocal regimes.

description: We study the one-loop effective action for $6D,$ ${\cal N}=(1,0)$ supersymmetric Yang--Mills (SYM) theory with hypermultiplets and $6D,$ ${\cal N}=(1,1)$ SYM theory as a subclass of the former, using the off-shell formulation of these theories in $6D,$ ${\cal N}=(1,0)$ harmonic superspace. We develop the corresponding supergraph technique and apply it to compute the one-loop divergences in the background field method ensuring the manifest gauge invariance. We calculate the two-point Green functions of the gauge superfield and the hypermultiplet, as well as the three-point gauge-hypermultipet Green function. Using these Green functions and exploiting gauge invariance of the theory, we find the full set of the off-shell one-loop divergent contributions, including the logarithmic and power ones. Our results precisely match with those obtained earlier in [1,2] within the proper time superfield method.

description: We study a strongly interacting dense hard-sphere system confined between two parallel plates by event-driven molecular dynamics simulations to address the fundamental question of the nature of the 3D to 2D crossover. As the fluid becomes more and more confined the dynamics of the transverse and lateral degrees of freedom decouple, which is accompanied by a diverging time scale separating 2D from 3D behavior. Relying on the time-correlation function of the transversal kinetic energy the scaling behavior and its density-dependence is explored. Surprisingly, our simulations reveal that its time-dependence becomes purely exponential such that memory effects can be ignored. We rationalize our findings quantitatively in terms of an analytic theory which becomes exact in the limit of strong confinement.

description: Reinforcement learning is considered to be a strong AI paradigm which can be used to teach machines through interaction with the environment and learning from their mistakes. Despite its perceived utility, it has not yet been successfully applied in automotive applications. Motivated by the successful demonstrations of learning of Atari games and Go by Google DeepMind, we propose a framework for autonomous driving using deep reinforcement learning. This is of particular relevance as it is difficult to pose autonomous driving as a supervised learning problem due to strong interactions with the environment including other vehicles, pedestrians and roadworks. As it is a relatively new area of research for autonomous driving, we provide a short overview of deep reinforcement learning and then describe our proposed framework. It incorporates Recurrent Neural Networks for information integration, enabling the car to handle partially observable scenarios. It also integrates the recent work on attention models to focus on relevant information, thereby reducing the computational complexity for deployment on embedded hardware. The framework was tested in an open source 3D car racing simulator called TORCS. Our simulation results demonstrate learning of autonomous maneuvering in a scenario of complex road curvatures and simple interaction of other vehicles.

description: Maximum Principles on unbounded domains play a crucial role in several problems related to linear second-order PDEs of elliptic and parabolic type. In the present notes, based on a joint work with prof. E. Lanconelli, we consider a class of sub-elliptic operators L in R^N and we establish some criteria for an unbounded open set to be a Maximum Principle set for L. We extend some classical results related to the Laplacian(proved by Deny, Hayman and Kennedy) and to the sub-Laplacians on homogeneous Carnot groups (proved by Bonfiglioli and Lanconelli).

description: Possible existence of chaotic oscillations in ion dynamics in the sheath and pre-sheath regions of a dusty plasma, induced by externally driven dust-charge fluctuation, is presented in this work. In a complex plasma, dust charge fluctuation occurs continuously with time due to the variation of electron and ions current flowing into the dust particles. In most of the works related to dust-charge fluctuation, theoretically it is assumed that the average dust-charge fluctuation follows the the plasma perturbation, while in reality, the dust-charge fluctuation is a semi-random phenomena, fluctuating about some average value. The very cause of dust-charge fluctuation in a dusty plasma also points to the fact that these fluctuations can be driven externally by changing electron and ion currents to the dust particles. With the help of a \emph{hybrid}-Particle in Cell-Monte Carlo (\emph{h}-PIC-MCC) code in this work, we use the plasma sheath as a candidate for driving the dust-charge fluctuation by periodically exposing the sheath-side wall to UV radiation, causing photoemission of electrons, which in turn drive the dust-charge fluctuation. We show that this \emph{driven} dust-charge fluctuation can induce a chaotic response in the ion dynamics in the sheath and the pre-sheath regions.

Asteroseismic Constraints on the Models of Hot B Subdwarfs: Convective Helium-Burning Cores

description: Asteroseismology of non-radial pulsations in Hot B Subdwarfs (sdB stars) offers a unique view into the interior of core-helium-burning stars. Ground-based and space-borne high precision light curves allow for the analysis of pressure and gravity mode pulsations to probe the structure of sdB stars deep into the convective core. As such asteroseismological analysis provides an excellent opportunity to test our understanding of stellar evolution. In light of the newest constraints from asteroseismology of sdB and red clump stars, standard approaches of convective mixing in 1D stellar evolution models are called into question. The problem lies in the current treatment of overshooting and the entrainment at the convective boundary. Unfortunately no consistent algorithm of convective mixing exists to solve the problem, introducing uncertainties to the estimates of stellar ages. Three dimensional simulations of stellar convection show the natural development of an overshooting region and a boundary layer. In search for a consistent prescription of convection in one dimensional stellar evolution models, guidance from three dimensional simulations and asteroseismological results is indispensable.

Cosmological dynamics of spatially flat Einstein-Gauss-Bonnet models in various dimensions: High-dimensional $Λ$-term case

description: In this paper we perform a systematic study of spatially flat $[(3+D)+1]$-dimensional Einstein-Gauss-Bonnet cosmological models with $Λ$-term. We consider models that topologically are the product of two flat isotropic subspaces with different scale factors. One of these subspaces is three-dimensional and represents our space and the other is $D$-dimensional and represents extra dimensions. We consider no {\it ansatz} of the scale factors, which makes our results quite general. With both Einstein-Hilbert and Gauss-Bonnet contributions in play, $D=3$ and the general $D\geqslant 4$ cases have slightly different dynamics due to the different structure of the equations of motion. We analytically study equations of motion in both cases and describe all possible regimes with special interest on the realistic regimes. Our analysis suggests that the only realistic regime is the transition from high-energy (Gauss-Bonnet) Kasner regime, which is the standard cosmological singularity in that case, to the anisotropic exponential regime with expanding three and contracting extra dimensions. Availability of this regime allows us to put constraint on the value of Gauss-Bonnet coupling $α$ and the $Λ$-term -- this regime appears in two regions on $(α, Λ)$ plane: $α< 0$, $Λ> 0$, $αΛ\leqslant 1/2$ and $α> 0$, $αΛ\leqslant (3D^2 - 7D + 6)/(4D(D-1))$, including entire $Λ< 0$ region. The obtained bounds are confronted with the restrictions on $α$ and $Λ$ from other considerations, like causality, entropy-to-viscosity ratio in AdS/CFT and others. Joint analysis constraints ($α$, $Λ$) even further: $α> 0$, $D \geqslant 2$ with $(3D^2 - 7D + 6)/(4D(D-1)) \geqslant αΛ\geqslant - (D+2)(D+3)(D^2 + 5D + 12)/(8(D^2 + 3D + 6)^2)$.

Δ-cumulants in terms of moments

Publisher: name: arXiv
Year: 2017
Subjects: subject: Combinatorics (math.CO)

description: The Δ-convolution of real probability measures, introduced by Bożejko, generalizes both free and boolean convolutions. It is linearized by the Δ-cumulants, and Yoshida gave a combinatorial formula for moments in terms of Δ-cumulants, that implicitly defines the latter. It relies on the definition of an appropriate weight on noncrossing partitions. We give here two different expressions for the Δ-cumulants: the first one is a simple variant of Lagrange inversion formula, and the second one is a combinatorial inversion of Yoshida's formula involving Schröder trees.
On s-harmonic functions on cones

Publisher: name: Bruno Pini Mathematical Analysis Seminar
Year: 2019
Subjects: subject: fractional Laplacian; conic functions; asymptotic behavior; Martin kernel
subject: 35R11; 35B45; 35B08

description: We deal with non negative functions which are s-harmonic on a given cone of the n-dimensional Euclidean space with vertex at zero, vanishing on the complementary. We consider the case when the parameter s approaches 1, wondering whether solutions of the problem do converge to harmonic functions in the same cone or not. Surprisingly, the answer will depend on the opening of the cone through an auxiliary eigenvalue problem on the upper half sphere. These conic functions are involved in the study of the nodal regions in the case of optimal partitions and other free boundary problems and play a crucial role in the extension of the Alt-Caffarelli-Friedman monotonicity formula to the case of fractional diffusions.

description: Modern machine learning models are often constructed taking into account multiple objectives, e.g., minimizing inference time while also maximizing accuracy. Multi-objective hyperparameter optimization (MHPO) algorithms return such candidate models, and the approximation of the Pareto front is used to assess their performance. In practice, we also want to measure generalization when moving from the validation to the test set. However, some of the models might no longer be Pareto-optimal which makes it unclear how to quantify the performance of the MHPO method when evaluated on the test set. To resolve this, we provide a novel evaluation protocol that allows measuring the generalization performance of MHPO methods and studying its capabilities for comparing two optimization experiments.

description: This note focuses on the geometric-theoretic analysis of the nodal set of solutions to specific degenerate or singular equations. As they belong to the Muckenhoupt class A_2, these operators appear in the seminal works of Fabes, Kenig, Jerison and Serapioni. In particular, they have recently attracted a lot of attention in the last decade due to their link to the local realization of the fractional Laplacian. The goal is to get a glimpse of the complete theory of the nodal set of solutions of such equations in the spirit of the seminal works of Hardt, Simon, Han and Lin.

An analysis of bitcoin spot and futures markets
Creators: name: Ozvatic, Stephen
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: Bitcoin is a decentralised virtual currency that uses cryptography to remove the need for trust between agents and intermediaries. Though it is deemed a currency, the cryptographic nature of bitcoin gives it characteristics similar to commodities, for example, gold. This thesis examines the relationship between spot and futures prices in the bitcoin market. It also applies the well known Gibson-Schwartz model to the pricing of bitcoin futures contracts. A sample from March 2013 to February 2015 is considered, including two separate periods of substantial increase in the bitcoin spot market. Findings suggest that the futures market was significantly in contango, with convenience yields often below -100% p.a. and significant arbitrage profits readily available. The convenience yield is found to be mean-reverting and decreasing in magnitude since 2013, with the market inefficiently pricing convenience yield risk. A negative relationship between the convenience yield and spot price volatility is observed, drawing comparisons with the electricity market. Overall, the Gibson-Schwartz model is found to provide a good fit to nearest-term futures contracts, while it fails to appropriately price bitcoin futures with longer maturities.

description: Maximum principles play an important role in the theory of elliptic equations. In the last decades there have been many contributions related to the development of fully nonlinear equations and viscosity solutions. Here we consider degenerate elliptic equations, where the main term is a partial trace of the Hessian matrix of the solution. We establish maximum principles in domains that are unbounded in some directions, contained in slabs, and extended maximum principles, which lead to removable singularity results.

description: The existence of axions or Axion-Like Particles (ALPs) has been predicted by various Beyond Standard Model (BSM) theories, and the proposed photon-ALP interaction is one of the ways to probe them. Such an interaction will lead to photon-ALP resonant conversion in galaxy clusters, resulting in a polarized spectral distortion in the CMB along the cluster line of sight. The estimation of this signal from galaxy clusters requires an estimation of their electron density and magnetic field profiles, as well as their redshifts. We have developed a new Bayesian framework \texttt{SpectrAx} that can use observations from different electromagnetic bands such as radio, CMB, optical, and X-ray to infer the astrophysical properties of a galaxy cluster, such as cluster its redshift, electron density and magnetic field, along with the BSM physics such as ALPs. We use simulated redshifts in our analysis, but that can be obtained by cross-matching with optical surveys having overlapping sky regions with the galaxy clusters. Also, we use radial profiles that are motivated from observations of galaxy clusters at low redshifts. By using the simulated data corresponding to the ALP mass of $10^{-14}$ eV for upcoming CMB surveys such as Simons Observatory (SO) and CMB-S4 in combination with Square Kilometer Array (SKA) and extended ROentgen Survey with an Imaging Telescope Array (eROSITA) we demonstrate the capability in accurately inferring the ALPs coupling strength along with the radial profile of electron density and magnetic field from galaxy clusters. The application of this framework to the data from future surveys by combining SKA+SO+eROSITA and SKA+CMB-S4+eROSITA will make it possible for the first time to explore both astrophysics and BSM physics from low-redshift galaxy clusters using a multi-band approach.

description: We prove the existence and uniqueness of global solutions to the Boltzmann equation with non-cutoff soft potentials in the whole space when the initial data is a small perturbation of a Maxwellian with polynomial decay in velocity. Our method is based in the decomposition of the desired solution into two parts: one with polynomial decay in velocity satisfying the Boltzmann equation with only a dissipative part of the linearized operator ; the other with Gaussian decay in velocity verifying the Boltzmann equation with a coupling term.

description: Objective: The goal of this contribution is to gather and to critically analyze recent evidence regarding the potential of exergaming for Parkinson’s disease (PD) rehabilitation and to provide an up-to-date analysis of the current state of studies on exergame-based therapy in PD patients. Methods: We performed our search based on the conclusions of a previous systematic review published in 2014. Inclusion criteria were articles published in the indexed databases Pubmed, Scopus, Sciencedirect, IEEE and Cochrane published since January 1, 2014. Exclusion criteria were papers with a target group other than PD patients exclusively, or contributions not based on exergames. Sixty-four publications out of 525 matches were selected. Results: The analysis of the 64 selected publications confirmed the putative improvement in motor skills suggested by the results of the previous review. The reliability and safety of both Microsoft Kinect and Wii Balance Board in the proposed scenarios was further confirmed by several recent studies. Clinical trials present better (n = 5) or similar (n = 3) results than control groups (traditional rehabilitation or regular exercise) in motor (TUG, BBS) and cognitive (attention, alertness, working memory, executive function), thus emphasizing the potential of exergames in PD. Pilot studies (n = 11) stated the safety and feasibility of both Microsoft Kinect and Wii Balance Board, potentially in home scenarios as well. Technical papers (n = 30) stated the reliability of balance and gait data captured by both devices. Related metaanalyses and systematic reviews (n = 15) further support these statements, generally citing the need for adaptation to patient’s skills and new input devices and sensors as identified gaps. Conclusion: Recent evidence indicates exergame-based therapy has been widely proven to be feasible, safe, and at least as effective as traditional PD rehabilitation. Further insight into new sensors, best practices and different cognitive stadiums of PD (such as PD with Mild Cognitive Impairment), as well as task specificity, are required. Also, studies linking game parameters and results with traditional assessment methods, such as UPDRS scores, are required. Outcomes for randomized controlled trials (RCTs) should be standardized, and follow-up studies are required, particularly for motor outcomes.

description: Stream ciphers are symmetric cipher systems which provide confidentiality in many applications ranging from mobile phone communication to virtual private networks. They may be implemented effciently in software and hardware and are a preferred choice when dealing with resource-constrained environments, such as smart cards, RFID tags,and sensor networks. This dissertation addresses cryptanalysis of several stream ciphers, and a hash function based on stream cipher. Also, the thesis investigates the design principles and security of stream ciphers built from nonlinear feedback shift registers. In a design view, any cryptographic attack shows a weak point in the design and immediately can be converted into an appropriate design criterion. Firstly, this thesis focuses on the WG-7, a lightweight stream cipher. It is shown that thekey stream generated by WG-7 can be distinguished from a random sequence with a negligible error probability. In addition, a key-recovery attack on the cipher has been successfully proposed. Then, a security evaluation of the Rakaposhi stream cipher identifies weaknesses of the cipher. The main observation shows that the initialisation procedure has a sliding property. This property can be used to launch distinguishing and key-recovery attacks. Further, the cipher is studied when the registers enter short cycles. In this case, the internal state can be recovered with less complexity than exhaustive search. New security features of a specific design based on nonlinear feedback shift registers have been explored. The idea applies a distinguishing attack on linearly filtered nonlinear feedback shift registers. The attack extends the idea on linear combinations of linearly filtered nonlinear feedback shift registers as well. The proposed attacks allow the attacker to mount linear attacks to distinguish the output of the cipher and recover its internal state. The next topic analyses a new lightweight communication framework called NLM-MAC. Several critical cryptographic weaknesses leading to key-recovery and forgery attack have been indicated. It is shown that the adversary can recover the internal state of the NLM generator. The attacker also is able to forge any MAC tag in real time. The proposed attacks are completely practical and break the scheme. Another part demonstrates some new cryptographic attacks on RC4(n,m) stream cipher. The investigations have revealed several weaknesses of the cipher. Firstly, a distinguisher for the cipher is proposed. Secondly, a key-recovery attack uses a method to find the secret key in real time. Finally, the RC4-BHF hash function that is based on the well-known RC4 stream cipher is analysed. Two attacks on RC4-BHF have been developed. In the first attack, the adversary is able to find collisions for two different messages. The second attack shows how to design a distinguisher that can tell apart the sequence generated by RC4-BHF from a random one.

description: The kinetics and mechanism of the oxidation of proposed vanadium (IV) species at conditions prevalent in the Stretford desulphurisation process have been investigated in this study. The British Gas Stretford Process employs vanadate to oxidise hydrogen sulphide to elemental sulphur, and the vanadium (IV) formed by the process is reoxidised to vanadium (V) by air oxidation in the presence of a catalyst.

description: In many studies, it is common to use binary (i.e., unweighted) edges to examine networks of entities that are either adjacent or not adjacent. Researchers have generalized such binary networks to incorporate edge weights, which allow one to encode node--node interactions with heterogeneous intensities or frequencies (e.g., in transportation networks, supply chains, and social networks). Most such studies have considered real-valued weights, despite the fact that networks with complex weights arise in fields as diverse as quantum information, quantum chemistry, electrodynamics, rheology, and machine learning. Many of the standard network-science approaches in the study of classical systems rely on the real-valued nature of edge weights, so it is necessary to generalize them if one seeks to use them to analyze networks with complex edge weights. In this paper, we examine how standard network-analysis methods fail to capture structural features of networks with complex edge weights. We then generalize several network measures to the complex domain and show that random-walk centralities provide a useful approach to examine node importances in networks with complex weights.

description: The phenomenon of spin transfer torque (STT) has attracted a great deal of interests due to its promising prospects in practical spintronic devices. In this paper, we report a theoretical investigation of STT in a noncollinear magnetic tunnel junction under ac modulation based on the nonequilibrium Green's function formalism, and derive a closed-formulation for predicting the time-averaged STT. Using this formulation, the ac STT of a carbon-nanotube-based magnetic tunnel junction is analyzed. Under ac modulation, the low-bias linear (quadratic) dependence of the in-plane (out-of-plane) torque on bias still holds, and the $\sinθ$ dependence on the noncollinear angle is maintained. By photon-assisted tunneling, the bias-induced components of the in-plane and out-of-plane torques can be enhanced significantly, about 12 and 75 times, respectively. Our analysis reveals the condition for achieving optimized STT enhancement and suggests that ac modulation is a very effective way for electrical manipulation of STT.

description: Digital Literacy (formerly ICT Capability) is one of the seven general capabilities outlined in the Australia curriculum designed to equip young people with the knowledge, skills, behaviours and dispositions to live and work in the twenty-first century (ACARA, 2021). The modern world is increasingly digital, with immense technological literacy required for many job roles and career paths. For this reason, technology in education has been and will continue to be a focus point for Australian schools and beyond. While opinion commonly supports the premise that there is a need to prepare our children for a digital world, successfully deploying such programs in schools has been fragmented (ACARA, 2014). This study explores the common factors that lead to successful technology programs being deployed in schools and further builds on existing knowledge of whether peer facilitation can further support a classroom technology environment. Through a Design-Based Research (DBR) approach, this thesis explores these factors firsthand, collecting rich data to inform the continuous improvement of a classroom program and then analyses the completed dataset through a Reflexive Thematic Analysis (Braun & Clarke, 2021) process. Rigour applied to a conclusive dataset via thematic analysis performed over the top of DBR analysis is methodologically significant and novel to the broader research community. This study provides a valuable contribution to the field of educational technology by combining theory with practice in working classroom environments to suggest a framework based on the successful factors that include teacher professional learning, device to student ratio, financial investment and the new factor of student peer leadership. This framework gives a practical direction for future planning and deployment of programs.

description: Yellow hypergiants are rare and represent a fast evolutionary stage of massive evolved stars. That evolutionary phase is characterised by a very intense mass loss, the understanding of which is still very limited. Here we report ALMA Compact Array observations of a 50$"$-mosaic toward the Fried Egg nebula, around one of the few Galactic yellow hypergiants IRAS 17163-3907. The emission from the $^{12}$CO J=2-1 line, H30$α$ recombination line, and continuum is imaged at a resolution of $\sim$8$"$, revealing the morphology of the molecular environment around the star. The continuum emission is unresolved and peaks at the position of the star. The radio recombination line H30$α$ shows unresolved emission at the star, with an approximately gaussian spectrum centered on a velocity of 21$\pm$3~km/s with a width of 57$\pm$6~km/s. In contrast, the CO 2-1 emission is complex and decomposes into several components beyond the contamination from interstellar gas in the line of sight. The CO spectrum toward the star is a broad plateau, centered at the systemic velocity of +18 km/s and with an expansion velocity of 100$\pm$10 km/s. Assuming isotropic and constant mass-loss, we estimate a mass-loss rate of 8$\pm$1.5 $\times10^{-5}$~M$_\odot$ yr$^{-1}$. At a radius of 25$"$ from the star, we detect CO emission associated with the dust ring previously imaged by {\it Herschel}. The kinematics of this ring, however, is not consistent with an expanding shell, but show a velocity gradient of $v_{sys} \pm$20 km/s. In addition, we find a puzzling bright feature radially connecting the star to the CO ring, at a velocity of +40 km/s relative to the star. This spur feature may trace a unidirectional ejection event from the star. Our ACA observations reveal the complex morphology around IRAS 17163 and illustrate the breakthroughs that ALMA will bring to the field of massive stellar evolution.
