description: Spherical nanoparticles (NPs) of size 14 nm, made of intermetallic Fe2CoAl (FCA) Heusler alloy, are synthesized via the co-precipitation and thermal deoxidization method. X-ray diffraction (XRD) and selected area electron diffraction (SAED) patterns confirm that the present nanoalloy is crystallized in A2-disordered cubic Heusler structure. Magnetic field (H) and temperature (T) dependent magnetization (M) results reveal that the NPs are soft ferromagnetic (FM) with high saturation magnetization (Ms) and Curie temperature (Tc). Fe2CoAl nanoalloy does not follow the Slater Pauling (SP) rule, possibly because of the disorder present in the system. We also investigate its magnetic phase transition (MPT) and magnetocaloric (MC) properties. The peak value of the magnetic entropy change vs T curve at a magnetic field change of 20 kOe corresponds to about 2.65 J/kg-K, and the observed value of refrigeration capacity (RCP) is as large as 44 J/kg, suggesting a large heat conversion in magnetic refrigeration cycle. The Arrott plot and the nature of the universal curve accomplish that the FM to paramagnetic (PM) phase transition in Fe2CoAl nanoalloy is of second-order. The present study suggests that the Fe2CoAl nanoscale system is proficient, useful and a good candidate for the spintronics application and opens up a window for further research on full-Heusler based magnetic refrigerants.

description: The history of stellar seismology suggests that observation and theory often take turns advancing our understanding. The recent tripling of the sample of pulsating white dwarfs generated by the Sloan Digital Sky Survey represents a giant leap on the observational side. The time is ripe for a comparable advance on the theoretical side. There are basically two ways we can improve our theoretical understanding of pulsating stars: we can improve the fundamental ingredients of the models, or we can explore the existing models in greater computational detail. For pulsating white dwarfs, much progress has recently been made on both fronts: models now exist that connect the interior structure to its complete evolutionary history, while a method of using parallel computers for global exploration of relatively simple models has also been developed. Future advances in theoretical white dwarf asteroseismology will emerge by combining these two approaches, yielding unprecedented insight into the physics of diffusion, nuclear burning, and mixing.

description: The first binary neutron star merger has already been detected in gravitational waves. The signal was accompanied by an electromagnetic counterpart including a kilonova component powered by the decay of radioactive nuclei, as well as a short $γ$-ray burst. In order to understand the radioactively-powered signal, it is necessary to simulate the outflows and their nucleosynthesis from the post-merger disk. Simulating the disk and predicting the composition of the outflows requires general relativistic magnetohydrodynamical (GRMHD) simulations that include a realistic, finite-temperature equation of state (EOS) and self-consistently calculating the impact of neutrinos. In this work, we detail the implementation of a finite-temperature EOS and the treatment of neutrinos in the GRMHD code HARM3D+NUC, based on HARM3D. We include formal tests of both the finite-temperature EOS and the neutrino leakage scheme. We further test the code by showing that, given conditions similar to those of published remnant disks following neutron star mergers, it reproduces both recombination of free nucleons to a neutron-rich composition and excitation of a thermal wind.

description: We investigate the influence of ram-pressure stripping on the internal gas kinematics of simulated spiral galaxies. Additional emphasis is put on the question of how the resulting distortions of the gaseous disc are visible in the rotation curve and/or the full 2D velocity field of galaxies at different redshifts. A Milky-Way type disc galaxy is modelled in combined N-body/hydrodynamic simulations with prescriptions for cooling, star formation, stellar feedback, and galactic winds. This model galaxy moves through a constant density and temperature gas, which has parameters similar to the intra-cluster medium (ICM). Rotation curves (RCs) and 2D velocity fields of the gas are extracted from these simulations in a way that follows the procedure applied to observations of distant, small, and faint galaxies as closely as possible. We find that the appearance of distortions of the gaseous disc due to ram-pressure stripping depends on the direction of the acting ram pressure. In the case of face-on ram pressure, the distortions mainly appear in the outer parts of the galaxy in a very symmetric way. In contrast, in the case of edge-on ram pressure we find stronger distortions. The 2D velocity field also shows signatures of the interaction in the inner part of the disc. At angles smaller than 45 degrees between the ICM wind direction and the disc, the velocity field asymmetry increases significantly compared to larger angles. Compared to distortions caused by tidal interactions, the effects of ram-pressure stripping on the velocity field are relatively low in all cases and difficult to observe at intermediate redshift in seeing-limited observations.

description: Determination of the symmetry property of superconducting gaps has been a central issue in studies to understand the mechanisms of unconventional superconductivity. Although it is often difficult to completely achieve the aforementioned goal, the existence of superconducting nodes, one of the few important experimental signatures of unconventional superconductivity, plays a vital role in exploring the possibility of unconventional superconductivity. The interplay between superconducting nodes and topology has been actively investigated, and intensive research in the past decade has revealed various intriguing nodes out of the scope of the pioneering work to classify superconducting order parameters based on the point groups. However, a systematic and unified description of superconducting nodes for arbitrary symmetry settings is still elusive. In this paper, we develop a systematic framework to comprehensively classify superconducting nodes pinned to any line in momentum space. While most previous studies have been based on the homotopy theory, our theory is on the basis of the symmetry-based analysis of band topology, which enables systematic diagnoses of nodes in all nonmagnetic and magnetic space groups. Furthermore, our framework can readily provide a highly effective scheme to detect nodes in a given superconductor by using density functional theory and assuming symmetry properties of Cooper pairs (called pairing symmetries), which can reduce candidates of pairing symmetries. We substantiate the power of our method through the time-reversal broken and noncentrosymmetric superconductor CaPtAs. Our work establishes a unified theory for understanding superconducting nodes and facilitates determining superconducting gaps in materials combined with experimental observations.

On Power Law Inflation in DBI Models

Year: 2007
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Inflationary models in string theory which identify the inflaton with an open string modulus lead to effective field theories with non-canonical kinetic terms: Dirac-Born-Infeld scalar field theories. In the case of a $D$-brane moving in an AdS throat with a quadratic scalar field potential DBI kinetic terms allow a novel realization of power law inflation. This note adresses the question of whether this behaviour is special to this particular choice of throat geometry and potential. The answer is that for any throat geometry one can explicitly find a potential which leads to power law inflation. This generalizes the well known fact that an exponential potential gives power law inflation in the case of canonical kinetic terms.

The Contestation of Tech Ethics: A Sociotechnical Approach to Technology Ethics in Practice

Subjects: subject: Computers and Society (cs.CY)

description: This article introduces the special issue "Technology Ethics in Action: Critical and Interdisciplinary Perspectives". In response to recent controversies about the harms of digital technology, discourses and practices of "tech ethics" have proliferated across the tech industry, academia, civil society, and government. Yet despite the seeming promise of ethics, tech ethics in practice suffers from several significant limitations: tech ethics is vague and toothless, has a myopic focus on individual engineers and technology design, and is subsumed into corporate logics and incentives. These limitations suggest that tech ethics enables corporate "ethics-washing": embracing the language of ethics to defuse criticism and resist government regulation, without committing to ethical behavior. Given these dynamics, I describe tech ethics as a terrain of contestation where the central debate is not whether ethics is desirable, but what "ethics" entails and who gets to define it. Current approaches to tech ethics are poised to enable technologists and technology companies to label themselves as "ethical" without substantively altering their practices. Thus, those striving for structural improvements in digital technologies must be mindful of the gap between ethics as a mode of normative inquiry and ethics as a practical endeavor. In order to better evaluate the opportunities and limits of tech ethics, I propose a sociotechnical approach that analyzes tech ethics in light of who defines it and what impacts it generates in practice.

description: The agent-based Yard-Sale model of wealth inequality is generalized to incorporate exponential economic growth and its distribution. The distribution of economic growth is nonuniform and is determined by the wealth of each agent and a parameter $λ$. Our numerical results indicate that the model has a critical point at $λ=1$ between a phase for $λ< 1$ with economic mobility and exponentially growing wealth of all agents and a non-stationary phase for $λ\geq 1$ with wealth condensation and no mobility. We define the energy of the system and show that the system can be considered to be in thermodynamic equilibrium for $λ< 1$. Our estimates of various critical exponents are consistent with a mean-field theory (see following paper). The exponents do not obey the usual scaling laws unless a combination of parameters that we refer to as the Ginzburg parameter is held fixed as the transition is approached. The model illustrates that both poorer and richer agents benefit from economic growth if its distribution does not favor the richer agents too strongly. This work and the accompanying theory paper contribute to understanding whether the methods of equilibrium statistical mechanics can be applied to economic systems.

description: We study real-space condensation in a broad class of stochastic mass transport models. We show that the steady state of such models has a pair-factorised form which generalizes the standard factorized steady states. The condensation in this class of models is driven by interactions which give rise to a spatially extended condensate that differs fundamentally from the previously studied examples. We present numerical results as well as a theoretical analysis of the condensation transition and show that the criterion for condensation is related to the binding-unbinding transition of solid-on-solid interfaces.

description: The article is devoted to the classical problems about the relationships between elliptic functions and hyperelliptic functions of genus 2. It contains new results, as well as a derivation from them of well-known results on these issues. Our research was motivated by applications to the theory of equations and dynamical systems integrable in hyperelliptic functions of genus 2. We consider a hyperelliptic curve $V$ of genus 2 which admits a morphism of degree 2 to an elliptic curve. Then there exist two elliptic curves $E_i$, $i=1,2$, and morphisms of degree 2 from $V$ to $E_i$. We construct hyperelliptic functions associated with $V$ from the Weierstrass elliptic functions associated with $E_i$ and describe them in terms of the fundamental hyperelliptic functions defined by the logarithmic derivatives of the two-dimensional sigma functions. We show that the restrictions of hyperelliptic functions associated with $V$ to the appropriate subspaces in $\mathbb{C}^2$ are elliptic functions and describe them in terms of the Weierstrass elliptic functions associated with $E_i$. Further, we express the hyperelliptic functions associated with $V$ on $\mathbb{C}^2$ in terms of the Weierstrass elliptic functions associated with $E_i$. We derive these results by describing the homomorphisms between the Jacobian varieties of the curves $V$ and $E_i$ induced by the morphisms from $V$ to $E_i$ explicitly.

description: The analysis of the input data offers useful insights for any further processing steps. Despite FastQ/Fasta/SAM statistics extraction systems (like FastQC) exist, they depend on the underlying platform or require dedicated servers. HTML5 is a web technology capable of providing great performance for online and/or offline software development. We present a client side-only FastQ/Fasta/SAM information extractor (MuffinInfo), demonstrating the capabilities of HTML5. Our software focuses on efficiency/usability, including features like: FileReader API to handle files locally, Web Workers to perform faster costly operations without freezing the UI and SVG to seamlessly scale graphics across resolutions. MuffinInfo parses the input in chunks, keeping only the relevant information. This way, it can process large files locally, without fully loading them into RAM and without the need for a server. MuffinInfo presents the results in tabs, grouped by category. It lists general information like the number of reads and number of bases. Our application also makes use of charts to depict quality scores by number of bases, the k-mer spectrum and the GC content. From the standpoint of the user, there is no installer and no external requirements (libraries/virtual machines). (S)he only has to visit the website using a HTML5 compliant browser like Internet Explorer 11, Opera 25, Google Chrome 40 or Firefox 38.. MuffinInfo can also run entirely offline. Additionally, the data and the information are kept private because the input is processed on the user's machine. In our experience, HTML5 is a viable solution to develop easy to use and performant software across a large range of devices and operating systems. Our application is available at (ongoing development): muffininfo.sourceforge.net

description: For 30­-40% of patients with diffuse large B ­cell lymphoma (DLBCL), treatment is ineffective due to primary refractory disease or relapse. Using our RNA­seq workflow SePIA (http://anduril.org/sepia), we characterized the landscape of miRNA expression in matched, tumor sample pairs taken from patients before immuno-chemotherapy treatment and after relapse. Our aim was two­-fold: (1) to discover differentially expressed (DE) miRNAs with functional roles in more treatment­-resistant tumors, and (2) to discover consistently high or low expressed miRNAs with roles in treatment resistance.

Identification of miRNA­-regulated genes and signalling pathways provides novel therapeutic targets and sheds light on the processes underlying DLBCL progression after treatment. Experimental validation supports DE miRNAs as potential therapeutic markers. Preliminary analysis of aberrantly high and low­-expressed miRNAs suggests both oncogenic and tumor suppressive roles in cancer­-associated pathways.

Publisher: name: F1000Research
Year: 2015

description: In this work, we introduce a new statistical lossless compression method for genome sequences when a reference genome is available. A typical reference-based compression algorithm consists of two stages. First, a mapping describing variations between reference and target genomes is found. Then the mapping is stored as a compressed version of the genome. To reconstruct the original genome, both the mapping and reference genome are needed. These algorithms face a major problem. They rely on finding the best mapping and if the best mapping is not found, compression will not be efficient. In our new scheme, instead of using the best mapping we consider all possible mappings by using weighting techniques. As a result, we will design an efficient single-stage compression method that is a) resilient to misalignment errors and b) offers high compression rates.

description: In a quantum computation with pure states, the generation of large amounts of entanglement is known to be necessary for a speedup with respect to classical computations. However, examples of quantum computations with mixed states are known, such as the deterministic computation with one quantum qubit (DQC1) model [Knill and Laflamme, Phys. Rev. Lett. 81, 5672 (1998)], in which entanglement is at most marginally present, and yet a computational speedup is believed to occur. Correlations, and not entanglement, have been identified as a necessary ingredient for mixed-state quantum computation speedups. Here we show that correlations, as measured through the operator Schmidt rank, are indeed present in large amounts in the DQC1 circuit. This provides evidence for the preclusion of efficient classical simulation of DQC1 by means of a whole class of classical simulation algorithms, thereby reinforcing the conjecture that DQC1 leads to a genuine quantum computational speedup.

description: Σκοπός της μελέτης είναι η διερεύνηση της έννοιας της κουλτούρας στη σκέψη του Γκράμσι, καθώς και του ρόλου που αυτή επιτελεί στην σοσιαλιστική δημοκρατία που οραματίζεται ο φιλόσοφος. Αρχικά διερευνώνται τα βασικά στοιχεία που συνθέτουν τις έννοιες της κουλτούρας και της ιδεολογίας, ως τα απαραίτητα συστατικά για να πραγματοποιηθεί ο μετασχηματισμός της κοινωνίας και να εδραιωθεί η ηγεμονία του προλεταριάτου. Στη συνέχεια παρουσιάζονται τα στοιχεία που συνθέτουν την έννοια του οργανικού διανοουμένου και αναλύονται οι τρόποι με τους οποίους παρεμβαίνουν στην κοινωνία, προκειμένου να ενισχυθεί η ιστορική συνείδηση των εργατών. Κατόπιν, αναλύονται οι βασικοί εκπαιδευτικοί μηχανισμοί στο έργο του Γκράμσι και συγκεκριμένα οι αρχές που πρέπει να διέπουν την πρωτοβάθμια και δευτεροβάθμια εκαπαίδευση, για να επεκταθούμε στη συνέχεια στο ρόλο του Πανεπιστημίου και των Ακαδημιών. Εξετάζονται παράλληλα, ο ρόλος του Κόμματος στην προώθηση της συλλογικής βούλησης που απαιτείται για την αναδιάρθρωση της κοινωνίας, όπως και των εργοστασιακών συμβουλίων, ως το βασικό θεσμικό πλαίσιο, μέσα στο οποίο οργανώνεται η ταξική πάλη στο χώρο της παραγωγής. Τέλος γίνεται μία αναφορά στο ρόλο της δημοσιογραφίας στη διάχυση της νέας κουλτούρας.
description: This study aims to explore the concept of culture in the thought of Gramsci, and the role that it plays in the socialist republic envisioned by the philosopher. The key elements that compose the concepts of culture and ideology are initially explored as the necessary components that assist in the transformation of the society and in the consolidation of the hegemony of the proletariat. Then we present the building blocks of the concept of organic intellectuals and the ways they interfere in the society in order to enhance the historical consciousness of the workers. Furthermore, we analyze the main structures of the primary and secondary educational system, as well as those of the Academic world. In addition to that, we examine the role of the Party in promoting the collective will required for the transformation of the society, as well as the role of the factory councils as the basic institutional framework within which the class struggle is organized. Finally, there is a reference to the role of journalism in the diffusion of the new culture.

description: This thesis is an investigation into cultural variations in experiences of depression. With the aid of empirical data, and with a phenomenological outlook, the arguments presented in this work aim to give a comparative account of the significance of culture in shaping cross-cultural variations, as seen in Iran and the UK. Despite the existence of a large body of literature on cross-cultural variations in depression, a close examination of the ways in which culture shapes these variations has been mostly lacking. In this work, viewing experiences of depression as necessarily situated and embedded within a phenomenologically significant sociocultural context, I offer a way of understanding these dynamics and mechanisms. I situate different aspects of the experiences and narratives of depression, as seen in Iran, within the broader sociocultural context and the dominant discourse around depression. As such, I show the way in which these different elements form a network of meaning-making, understanding, and interpretation, that can be seen to underlie some of the variations in expressions and experiences of depression, as seen in Iran and the UK. I examine different elements in experience of depression and symptom reports, including somatic symptoms, metaphors in narratives, emotional difficulties, and disturbances to one’s normal way of being in the world, against the backdrop of culture within which these experiences and expressions find meaning. I therefore offer a way of understanding experiences as inherently bound with culture and cultural narratives. This positioning of culture at the centre of the investigation of experiences of depression, I argue, has important consequences for psychiatric thought and practice, as well as for phenomenological investigations, both of which have tended to offer presumptively universal criteria and accounts, without paying sufficient attention to cultural differences.

description: To address the challenge of representing and interrogating a large amount of sequence data, we are developing an algorithm that builds a simplified data structure and returns a graph as a multi-genome reference. It aids in representing genomes that differ over a range of diversities and tackles the bias against using only one reference genome.

description: В статье рассматривается современное системы нормирования и оплаты труда в сельскохозяйственных предприятиях. Основные проблемы, с которыми сталкиваются работники сельского хозяйства на предприятии: низкая заработная плата и нерегулярность ее выплаты. Уровень обоснованности применяемых норм труда в отрасли животноводства составляет 87%, а в отрасли растениеводстве 75%. Низкий уровень нормирования труда связан с отсутствием на большинстве сельскохозяйственных предприятий должности экономиста по труду, применения устаревших и необоснованных норм выработки и норм обслуживания, отсутствия зависимости уровня заработной платы от выполнения установленных норм труда. Для повышения эффективности сельскохозяйственного производства необходима реализация программы развития системы нормирования и оплаты труда в долгосрочной перспективе на федеральном, региональном уровне и уровне предприятий.The article deals with the modern system of rationing and remuneration of labor in agricultural enterprises. The main problems faced by agricultural workers in the enterprise: low wages and irregular payments. The level of validity of the applied labor standards in the livestock industry is 87%, and in the crop industry 75%. The low level of labor rationing is associated with the absence of the post of labor economist at most agricultural enterprises, the use of outdated and unreasonable standards of production and service standards, the absence of dependence of the wage level on the implementation of the established labor standards. To improve the efficiency of agricultural production, it is necessary to implement a program for the development of the system of regulation and remuneration of labor in the long term at the Federal, regional and enterprise levels.

description: H παρούσα μεταπτυχιακή εργασία πραγματεύεται τις επιρροές που δέχτηκε από την ελληνική αρχαιότητα η ελληνική τέχνη του μεσοπολέμου. Εμβαθύνει στην πολυσυζητημένη εποχή της δεκαετίας του ’30 και επικεντρώνεται σε ένα λιγότερο γνωστό κομμάτι της: την επαφή με τον αρχαίο ελληνικό πολιτισμό, χωρίς να εστιάζει στις ήδη γνωστές αναφορές στην τέχνη του Βυζαντίου και τη λαϊκή παράδοση. Επιλέξαμε να παρουσιάσουμε τους σημαντικότερους ζωγράφους της δεκαετίας και την επίδραση που αυτοί δέχτηκαν από την αρχαιότητα, μετουσιώνοντάς την σε μια νέα και ιδιαίτερη ελληνική καλλιτεχνική έκφραση, συντονισμένες με τις πολιτικές συνθήκες της εποχής στην Ελλάδα και την Ευρώπη. Πιο συγκεκριμένα, μελετήσαμε το έργο του Παρθένη, του Γουναρόπουλου του Κόντογλου, του Στέρη, του Γκίκα, του Εγγονόπουλου, του Νικολάου, του Τσαρούχη και του Θεόφιλου. Καταλήξαμε, τέλος, στην εκτίμηση πως η γενιά του ’30 έπρεπε να ακολουθήσει την Ευρώπη στις μεγάλες αλλαγές που συντελέστηκαν στο χώρο της τέχνης, αλλά, παράλληλα, θα ήταν αδύνατον να μην επηρεαστεί από τις πολιτικές και κοινωνικές εξελίξεις που συνέβαιναν τα τελευταία χρόνια στην Ελλάδα. Η τέχνη έπρεπε να ισορροπήσει ανάμεσα στο τοπικό και το παγκόσμιο, και καθώς φαίνεται κατάφερε να δημιουργήσει κάτι μοναδικό, που συνέχισε να απασχολεί και να εμπνέει και τις επόμενες γενιές.
description: The current thesis discusses how the Greek art of the interwar period was influenced by ancient Greece. It gives emphasis to the much vaunted era of the '30s and focuses on a lesser known part; the contact with the ancient Greek culture, without focusing on already known references to the Byzantine art and the folklore. We chose to present the most important painters of the decade and the impact that they received from antiquity, transforming it into a new and special Greek artistic expression, coordinated with the political conditions of the time in Greece and Europe. More specifically, we studied the work of Parthenis, Gounaropoulos, Kontoglou, Steris, Ghikas, Engonopoulos, Nicholaou, Tsarouhis and Theophilos. Finally, we came to the conclusion that the 30s generation should have followed Europe on major changes to the world of art, but at the same time it would be impossible not to be influenced by the political and social developments that occurred in Greece during that period. The art had to maintain a balance between the local and the global which created something unique that continued to engage and inspire future generations.
In support of a diversity of methods : eyewitness memory in actual cases of robbery and fraud
Creators: name: Tollestrup, Patricia Ann

description: Much of our knowledge of eyewitness memory is built on laboratory based studies. In recent years this has caused a controversy, the resolution of which seems to be an acceptance of the need to learn about eyewitness memory from a variety of methods such as field studies, case, and archival research. The thesis reports an archival analysis of actual Royal Canadian Mounted Police case files of robbery and fraud. Previous research on the configuration of robberies was replicated. The majority of robberies are victim-only crimes that do not involve bystander eyewitnesses. Robbery victims and witnesses provided more details (10.96 and 9.37 respectively) regarding the perpetrator’s appearance than fraud victims (2.11). Less than 10% of robbery victims and witnesses, but almost 75% of fraud victims were unable to describe the perpetrator. All eyewitnesses tended to overestimate age and underestimate height and weight. Identification outcomes were analyzed according to the evidence category of the perpetrator (Confession, Implicating and None). The likeithood that the police suspect was indeed the actual perpetrator is assumed to be highest in the Confession condition and lowest in the None condition. In the Confession condition, the police suspect was selected by 84.6% of robbery victims, 55.55 of robbery witnesses and by 22.7% of fraud victims. Identification accuracy was adversely influence by the average delay between the crime and attempting an identification. Delay was a confound in these analyses as on average, victims of robbery attempted their identifications sooner than both robbery witnesses and fraud victims. Limited support was found for the weapon focus phenomenon. Weapon presence (in robbery cases only) did not influence descriptions (amount or accuracy). Weapon presence did not significantly adversely influence identification accuracy, but was close to obtaining significance (p = .061). The present analysis demonstrated the feasibility as well as the utility of archival research.

Flavor Dependent $U(1)$ Symmetric Zee Model with a Vector-like Lepton

description: We extend the Zee model by introducing a vector-like lepton doublet and a flavor dependent global $U(1)$ symmetry. Flavor changing neutral currents in the quark sector can be naturally forbidden at tree level due to the $U(1)$ symmetry, while sufficient amount of lepton flavor violation is provided to explain current neutrino oscillation data. In our model, additional sources of CP-violation appear in the lepton sector, but their contribution to electric dipole moments is much smaller than current experimental bounds due to the Yukawa structure constrained by the $U(1)$ symmetry. We find that there is a parameter region where the strongly first order electroweak phase transition can be realized, which is necessary for the successful scenario of the electroweak baryogenesis in addition to new CP-violating phases. In the benchmark points satisfying neutrino data, lepton flavor violation data and the strongly first order phase transition, we show that an additional CP-even Higgs boson $H$ mainly decays into a lighter CP-odd Higgs boson $A$, i.e., $H \to AZ$ or $H \to AA$ with a characteristic pattern of lepton flavor violating decays of $A$.
