Asconius on Cicero’s Son-in-law Lentulus, his Apprenticeship under Pupius Piso, and the De Othone
Creators: name: Ramsey, John T.
Publisher: name: Ciceroniana on line
Year: 2021

description: This paper covers three separate topics. All three concern Cicero and his first-century AD commentator Q. Asconius Pedianus. The chief contribution of parts one and two is to identify sources consulted by Asconius that have previously not been revealed or suspected. Part one will show that the multiple errors committed by Asconius in recounting the circumstances of the death of Cicero’s daughter Tullia in 45 BC are to be attributed to a source that misunderstood a letter of Cicero. Prior to publication, the letters to Atticus appear to have been accessible in a private archive, and on at least one, and probably two occasions, Asconius reveals that the historian Fenestella was misled by identifiable letters of Cicero to Atticus. Therefore, it is plausible that Fenestella was the conduit by which the content of yet another letter left its imprint on Asconius. In part two, it will be demonstrated that Asconius is likely to have relied upon, and been misled by, the invective against Cicero that has come down to us under the name of Sallust. This borrowing provides an earlier terminus post quem non for the circulation of that pseud-epigraphic work. At the same time, it demonstrates that Asconius, like Quintilian after him, almost certainly accepted the invective as a genuine work by Sallust. Lastly, part three challenges the communis opinio that a hostile reaction of a theatre crowd to the praetor L. Roscius Otho in 63 was caused by their resentment of his law of 67 which conferred on knights the privilege of occupying the first fourteen rows of seats. According to the prevailing view, Cicero’s no longer extant oration De Othone persuaded the throng to set aside their anger over being barred from the front rows. This paper argues that the angry outburst was triggered instead by the role Otho played as urban praetor in overseeing cases involving the repayment of debts, which in 63 had become a politically charged issue.

description: Type II supernovae (SNe) originate from the explosion of hydrogen-rich supergiant massive stars. Their first electromagnetic signature is the shock breakout, a short-lived phenomenon which can last from hours to days depending on the density at shock emergence. We present 26 rising optical light curves of SN II candidates discovered shortly after explosion by the High cadence Transient Survey (HiTS) and derive physical parameters based on hydrodynamical models using a Bayesian approach. We observe a steep rise of a few days in 24 out of 26 SN II candidates, indicating the systematic detection of shock breakouts in a dense circumstellar matter consistent with a mass loss rate $\dot{M} > 10^{-4} M_\odot yr^{-1}$ or a dense atmosphere. This implies that the characteristic hour timescale signature of stellar envelope SBOs may be rare in nature and could be delayed into longer-lived circumstellar material shock breakouts in most Type II SNe.

title: Correlations Between Cranial and Inner Ear Morphologies of Odontocetes

subject: Echolocation

subject: Cranial telescoping

description: The odontocete skull shows features that indicate specialized behaviors implemented during the animal's life such as echolocation and feeding preference. Echolocation is a highly specialized adaptation for feeding and navigation that involves the production of high frequency sound and the reception of its echo. Previous studies show that measurements of bony labyrinths of the inner ear show interspecific differences in hearing frequency ranges of odontocetes. We can use CT scanning technology to take detailed measurements of these features. Features of the inner ear that correlate with high frequency hearing include a low basal ratio, greater inter-turn distance, and lower number of turns of the cochlea. Cranial features such as asymmetry and telescoping may be involved in high frequency sound production. Odontocetes use echolocation to assist in a variety of methods to capture prey such as suction and raptorial feeding. These feeding strategies may be determined by cranial morphological features such as longirostry (long rostrum) and brevirostry (short rostrum). Finding adaptive and functional relationships between these features is an important part of understanding the evolution of odontocetes and how they behave today. To determine if there are any evolutionary correlations between cranial features for feeding, sound production, and sound reception, I collected existing measurement data of inner ear and cranial features ("characters") from a total of 65 extinct and extant odontocete species. These data incorporate all the major extinct and extant odontocete families. I mapped the characters onto phylogenetic trees. Phylogenetic generalized least squares statistical analysis was used on the phylogenetic trees to assess correlations between characters. The results provide evidence that cranial asymmetry is correlated with echolocation. There is no evidence that cranial telescoping is correlated with echolocation. The findings in this study also indicate that brevirostrine odontocetes emit higher frequencies than longirostrine odontocetes. Lastly, this study finds a positive correlation between most inner ear features, except for comparisons involving number of cochlear turns and basal ratio. This reflects how size dimensions of the cochlea are directly proportional to one another. This work highlights and clarifies relationships among cranial features for echolocation and feeding within odontocetes.

description: The binary system GG Tau A is observed to have a circumbinary disc with a dust ring located further out than expected, assuming a co-planar disc and a corresponding semi-major axis of 34 AU. Given the binary separation, this large cavity can be explained by relaxing the assumption of a co-planar disc and instead fit the observations with a mis-aligned circumbinary disc around an eccentric binary with a wider semi-major axis of 60 AU, consistent with fitting the proper motion data for the system. We run SPH simulations to check this possibility and indeed we find that a misalignment angle of 30 degrees and a binary eccentricity of 0.45 fit both the astrometric data and the disc cavity. However, such configuration could in principle be unstable to polar, rather that planar alignment. We investigate the secular evolution of this configuration and show that it is indeed stable throughout the disc lifetime.

description: In forthcoming years, connections between cosmology and particle physics will be made increasingly important with the advent of a new generation of cosmic microwave background (CMB) experiments. Here, we review a number of these links. Our primary focus is on new CMB tests of inflation. We explain how the inflationary predictions for the geometry of the Universe and primordial density perturbations will be tested by CMB temperature fluctuations, and how the gravitational waves predicted by inflation can be pursued with the CMB polarization. The CMB signatures of topological defects and primordial magnetic fields from cosmological phase transitions are also discussed. Furthermore, we review current and future CMB constraints on various types of dark matter (e.g. massive neutrinos, weakly interacting massive particles, axions, vacuum energy), decaying particles, the baryon asymmetry of the Universe, ultra-high-energy cosmic rays, exotic cosmological topologies, and other new physics.

description: As an attractive degree of freedom in electromagnetic (EM) waves, the orbital angular momentum (OAM) enables infinite communication channels for both classical and quantum communications. The exploration of OAM generation inspires various designs involving spiral phase plates, antenna arrays, metasurfaces, and computer-generated holograms. In this work, we theoretically and experimentally demonstrate an approach to producing OAM carrying EM waves by a point defect in three-dimensional (3D) photonic crystals (PCs). Simultaneous excitation of two vibrational-defect states with an elaborately engineered phase retardation generates a rotational state carrying OAM. Through converting guided waves in a line defect to localized waves in a point defect and then to radiated vortex waves in free space, the lowest four OAM-mode emitters, i.e., OAM indices of 1, -1, 2, and -2, are successfully realized. This work offers a physical mechanism to generate OAM by PCs, especially when the OAM generation is to be integrated with other designs.

description: When classical information is sent through a quantum channel of nonorthogonal states, there is a possibility that transmittable classical information exceeds a channel capacity in a single use of the initial channel by extending it into multi-product channel. In this paper, it is shown that this remarkable feature of a quantum channel, so-called superadditivity, appears even in as low as the third extended coding of the simplest binary input channel. A physical implementation of this channel is indicated based on cavity QED techniques.

description: We explore the constraints on the history of reionization from Planck 2015 Cosmic Microwave Background (CMB) data and we derive the forecasts for future CMB observations. We consider a class of monotonic histories of reionization as parametrized by two additional extra parameters with respect to the average optical depth used in the instantaneous reionization modeling. We investigate the degeneracies between the history of reionization and selected extensions of the standard cosmological model. In particular, we consider the degeneracies with the total mass of the neutrino sector and we discuss the possible correlation between the dark matter annihilation and the duration of reionization in the CMB. We use an extension to poly-reion model that was proposed in Hazra and Smoot, JCAP 1711, 028 (2017). We compare the constraints from Planck 2015 data with the predicted constraints from possible future CMB mission as LiteBIRD, and we also use the proposed CORE-like specifications as an example of what higher resolution can bring in addition. We find that the degeneracy between the average optical depth and the duration of reionization will be substantially removed by both concepts. Degeneracies between the reionization history and either the total neutrino mass and properties of dark matter annihilation will also be improved by future surveys. We find only marginal improvement in the constraints on reionization history for the higher resolution in the case of long duration of reionization.

description: The data collected by the NIITEK GPR, high range resolution (HRR) ground-penetrating radar (GPR), results in a digitized raw video representing signals re ected at the surface of as well as internal to the landmine due to changes in impedances, materials dielectric properties. This digitized signal has to undergo several stages of preprocessing in order to produce a binary-valued- sequence. A part of this sequence contains a speci c length of string that is a characteristic of a mine pattern. The mine pattern, to be recognized from a longer string of processed GPR data, has to be presented to a landmine detector. The landmine detector not only detects the mine but also classi es them and discriminates the mines from clutter (noise). Three pattern recognizers, one reset Finite State Machine (FSM) and two behaviorally equivalent Parallel Correlators are designed to detect multiple landmines simultaneously. Alternative implementations of these processing modules are compared with respect to chip area in terms of number of slices (real-estate or chip area) and speed (processing time), as a function of the number of landmines to be simultaneously recognized. It is found that the reset FSM is smallest in size of all the architectures but the slowest, whereas, the rst Parallel Correlator is largest in size and the second Correlator, the fastest. An alternative pattern recognizer, a non-reset Finite State Machine, sometimes known as a Rabin-Scott Machine, is also analyzed in terms of chip area (slices) and speed(processing time) but with respect to the relevant parameter, the maximum number of states in FSM. It was apparent that both- the size as well as the speed of the FSM increases with the increase in the number of states.

description: We present dark tridents, a new channel for exploring dark sectors in short-baseline neutrino experiments. Dark tridents are clean, distinct events where, like neutrino tridents, the scattering of a very weakly coupled particle leads to the production of a lepton--antilepton pair. Dark trident production occurs in models where long-lived dark-sector particles are produced along with the neutrinos in a beam-dump environment and interact with neutrino detectors downstream, producing an on-shell boson which decays into a pair of charged leptons. We focus on a simple model where the dark matter particle interacts with the standard model exclusively through a dark photon, and concentrate on the region of parameter space where the dark photon mass is smaller than twice that of the dark matter particle and hence decays exclusively into standard-model particles. We compute event rates and discuss search strategies for dark tridents from dark matter at the current and upcoming liquid argon detectors aligned with the Booster beam at Fermilab -- MicroBooNE, SBND, and ICARUS -- assuming the dark sector particles are produced off-axis in the higher energy NuMI beam. We find that MicroBooNE has already recorded enough data to be competitive with existing bounds on this dark sector model, and that new regions of parameter space will be probed with future data and experiments.

We demonstrate the formation of a trimer state of two electrons above the Fermi sea and the third electron, for sufficiently strong inter-band attractive interaction. We show that the critical interaction strength is the lowest for small Fermi velocities, large masses of the additional electron and large Debye energy. This trimer state competes with the formation of the two-electron Cooper pair, and can be created transiently via optical pumping.

AGN fueling & feedback from pc to kpc scale

Year: 2019

description: AGN fueling and feedback: presentation at IAU 356, Addis-Ababa Dynamical mechanisms are essential to exchange angular
 momentum, drive the gas to the center, and fuel the central
 super-massive black hole. While at 100pc scale, the gas is sometimes
 stalled in nuclear rings, recent observations reaching ~10pc scale
 may reveal the sphere of influence of the black hole, and smoking
 gun evidence of fueling.
 Observations of AGN feedback will be presented, together
 with the suspected responsible mechanisms. Molecular outflows are frequently
 detected in active galaxies with ALMA and NOEMA, with loading factors
 between 1 and 5. When driven by AGN with escape velocity,
 these outflows are therefore a clear way to moderate or suppress star formation.
 However, AGN feedback can be also positive, and evidence will be discussed.

description: We present a second epoch of {\it Chandra} observations of the Type Ia LMC SNR 0509-68.7 (N103B) obtained in 2017. When combined with the earlier observations from 1999, we have a 17.4-year baseline with which we can search for evidence of the remnant's expansion. Although the lack of strong point source detections makes absolute image alignment at the necessary accuracy impossible, we can measure the change in the diameter and the area of the remnant, and find that it has expanded by an average velocity of 4170 (2860, 5450) km s$^{-1}$. This supports the picture of this being a young remnant; this expansion velocity corresponds to an undecelerated age of 850 yr, making the real age somewhat younger, consistent with results from light echo studies. Previous infrared observations have revealed high densities in the western half of the remnant, likely from circumstellar material, so it is likely that the real expansion velocity is lower on that side of the remnant and higher on the eastern side. A similar scenario is seen in Kepler's SNR. N103B joins the rare class of Magellanic Cloud SNRs with measured proper motions.

description: U(1) family symmetries have led to successful predictions of the fermion mass spectrum and the mixing angles of the hadronic sector. In the context of the supersymmetric unified theories, they further imply a non-trivial mass structure for the scalar partners, giving rise to new sources of flavor violation. In the present work, lepton flavor non-conserving processes are examined in the context of the minimal supersymmetric standard model augmented by a U(1)-family symmetry. We calculate the mixing effects on the μ-> eγand τ-> μγrare decays. All supersymmetric scalar masses involved in the processes are determined at low energies using two loop renormalization group analysis and threshold corrections. Further, various novel effects are considered and found to have important impact on the branching ratios. Thus, a rather interesting result is that when the see-saw mechanism is applied in the (12 X 12)-sneutrino mass matrix, the mixing effects of the Dirac matrix in the effective light sneutrino sector are canceled at first order. In this class of models and for the case that soft term mixing is already present at the GUT scale, tau -> μγdecays are mostly expected to arise at rates significantly smaller than the current experimental limits. On the other hand, the $μ\ra e γ$ rare decays impose important bounds on the model parameters, particularly on the supersymmetric scalar mass spectrum. In the absence of soft term mixing at high energies, the predicted branching ratios for rare decays are, as expected, well below the experimental bounds.

The problem of the height dependence of magnetic fields in sunspots
Creators: name: Balthasar, Horst
Publisher: name: arXiv
Year: 2018
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: To understand the physics of sunspots, it is important to know the properties of their magnetic field, and especially its height stratification plays a substantial role. There are mainly two methods to assess this stratification, but they yield different magnetic gradients in the photospheric layers. Determinations based on the different origin of several spectral lines and the slope of their profiles result in gradients of -2 to -3G/km, or even steeper. This is similar for the total magnetic field strength and for the vertical component of the magnetic field. The other option is to determine the horizontal partial derivatives of the magnetic field, and with the condition divB=0, also the vertical derivative is known. With this method, gradients of -0.5 G/km and shallower are obtained. Obviously, these results do not agree. If chromospheric spectral lines are included, only shallow gradients around -0.5G/km are encountered. Shallow gradients are also found from gyro-resonance measurements in the radio wave range 300 - 2000GHz. Some indirect methods are also considered, but they cannot clarify the total picture. An analysis of a numerical simulation of a sunspot indicates a shallow gradient over a wide height range, but with slightly steeper gradients in deep layers. Several ideas to explain the discrepancy are also discussed. With no doubts cast on Maxwell's equations, the first one is to look at the uncertainties of the formation heights of spectral lines, but a wider range of these heights would require an extension of the solar photosphere that is incompatible with observations and the theory of stellar atmospheres. The problem of the height gradient of the magnetic field in sunspots is still not solved.

description: Autism is a cluster of highly heterogenous neurodevelopmental conditions that impacts differences in socio-emotional information processing; however, to date, little work has focused on the relevant brain systems involved in anxiety-related emotional processing in autistic youth. Importantly, despite recent efforts in broadening characterizations of the different presentations of autism based on sex assigned at birth, little is known about differences in psychopathological and neurodevelopmental trajectories between autistic girls and autistic boys. The present study interrogated neurodevelopmental differences in bilateral structural amygdala volumes in a sex balanced sample of autistic and nonautistic girls and boys aged 8-17 years old; we tested for effects of sex, IQ, diagnosis, along with anxiety problems and social behavior problems, in addition to interactions among these variables. Overall, between group comparisons did not reveal meaningful statistical differences in normalized left and right amygdala volumes when comparing autistic and typically developing (TD) counterparts. Autistic females (ASDf ) reported significantly greater anxiety problems relative to typically developing females TDf. Additionally, autistic males (ASDm) and ASDf did not differ on anxiety or social behavioral problem measures. As well, ASDf anxiety as a predictor of left or right amygdala volume did not survive statistical significance.

description: We study the possibility that the magnetic dipole moment of light charged vector mesons could be measured from their effects in τ^- --> V^-ν_τγdecays. We conclude that the energy spectrum and angular distribution of photons emitted at small angles with respect to vector mesons is sensitive the effects of the magnetic dipole moment. Model-dependent contributions and photon radiation off other electromagnetic multipoles are small in this region. We also compute the effects of the magnetic dipole moment on the integrated rates and photon energy spectrum of these $τ$ lepton decays.

description: My work investigates the role of care in society. I define care as a serious and tender attention to someone or something. Fastening the button on the back of my daughter’s dress without tangling it with her delicate strands of hair is an example of my own maternal caring. I want to make care visible, mentionable, and call into question the impact of the presence or absence of care. My work oscillates between tenderness and its opposite, documenting an unpredictable time. This survey of artwork created between 2019 – 2022 embodies my inquiry on care: swaddling gestures that reminded me of my now five-year-old daughter’s infancy, solitary contemplations of life and fear, paintings that capture fleeting moments, and a photobook created with my eight-month-old son by my side. These works culminate to tell a story of my own experience of motherhood while remaining permeable to interpretation, inviting you to consider the role of care in your life.
Noiseless Quantum Codes

description: In this paper we study a model quantum register $\cal R$ made of $N$ replicas (cells) of a given finite-dimensional quantum system S. Assuming that all cells are coupled with a common environment with equal strength we show that, for $N$ large enough, in the Hilbert space of $\cal R$ there exists a linear subspace ${\cal C}_N$ which is dynamically decoupled from the environment. The states in ${\cal C}_N$ evolve unitarily and are therefore decoherence-dissipation free. The space ${\cal C}_N$ realizes a noiseless quantum code in which information can be stored, in principle, for arbitrarily long time without being affected by errors.

Dissipation and Decoherence in a Quantum Register

Subjects: subject: Quantum Physics (quant-ph)

description: A model for a quantum register $\cal R$ made of $N$ replicas of a $d$-dimensional quantum system (cell) coupled with the environment, is studied by means of a Born-Markov Master Equation (ME). Dissipation and decoherence are discussed in various cases in which a sub-decoherent enconding can be rigorously found. For the qubit case ($d=2$) we have solved, for small $N,$ the ME by numerical direct integration and studied, as a function of the coherence length $ξ_c$ of the bath, fidelity and decoherence rates of states of the register. For large enough $ξ_c$ the singlet states of the global $su(2)$ pseudo-spin algebra of the register (noiseless at $ξ_c=\infty$) are shown to have a much smaller decoherence rates than the rest of the Hilbert space.

The Chaotic Long-term X-ray Variability of 4U 1705--44

description: The low-mass X-ray binary 4U1705-44 exhibits dramatic long-term X-ray time variability with a timescale of several hundred days. The All-Sky Monitor (ASM) aboard the Rossi X-ray Timing Explorer (RXTE) and the Japanese Monitor of All-sky X-ray Image (MAXI) aboard the International Space Station together have continuously observed the source from December 1995 through May 2014. The combined ASM-MAXI data provide a continuous time series over fifty times the length of the timescale of interest. Topological analysis can help us identify 'fingerprints' in the phase-space of a system unique to its equations of motion. The Birman-Williams theorem postulates that if such fingerprints are the same between two systems, then their equations of motion must be closely related. The phase-space embedding of the source light curve shows a strong resemblance to the double-welled nonlinear Duffing oscillator. We explore a range of parameters for which the Duffing oscillator closely mirrors the time evolution of 4U1705-44. We extract low period, unstable periodic orbits from the 4U1705-44 and Duffing time series and compare their topological information. The Duffing and 4U1705-44 topological properties are identical, providing strong evidence that they share the same underlying template. This suggests that we can look to the Duffing equation to help guide the development of a physical model to describe the long-term X-ray variability of this and other similarly behaved X-ray binary systems.

Finite Size Analysis of Luttinger Liquids with a source of 2k_f Scattering

description: Numerical analysis of the spectrum of large finite size Luttinger liquids (g<1) in the presence of a single source of 2k_f scattering has been made possible thanks to an effective integration of high degrees of freedom. Presence of irrelevant operators and their manifestation in transport are issues treated independently. We confirm the existence of two irrelevant operators: particle hopping and charge oscillations, with regions of dominance separated by g=1/2. Temperature dependence of conductance is shown to be dominated by hopping alone. Frequency dependence is affected by both irrelevant operators.

description: This study presents a system for sound source localization in time domain using a deep residual neural network. Data from the linear 8 channel microphone array with 3 cm spacing is used by the network for direction estimation. We propose to use the deep residual network for sound source localization considering the localization task as a classification task. This study describes the gathered dataset and developed architecture of the neural network. We will show the training process and its result in this study. The developed system was tested on validation part of the dataset and on new data capture in real time. The accuracy classification of 30 m sec sound frames is 99.2%. The standard deviation of sound source localization is 4°. The proposed method of sound source localization was tested inside of speech recognition pipeline. Its usage decreased word error rate by 1.14% in comparison with similar speech recognition pipeline using GCC-PHAT sound source localization.

Learning to Segment and Represent Motion Primitives from Driving Data for Motion Planning Applications

description: Developing an intelligent vehicle which can perform human-like actions requires the ability to learn basic driving skills from a large amount of naturalistic driving data. The algorithms will become efficient if we could decompose the complex driving tasks into motion primitives which represent the elementary compositions of driving skills. Therefore, the purpose of this paper is to segment unlabeled trajectory data into a library of motion primitives. By applying a probabilistic inference based on an iterative Expectation-Maximization algorithm, our method segments the collected trajectories while learning a set of motion primitives represented by the dynamic movement primitives. The proposed method utilizes the mutual dependencies between the segmentation and representation of motion primitives and the driving-specific based initial segmentation. By utilizing this mutual dependency and the initial condition, this paper presents how we can enhance the performance of both the segmentation and the motion primitive library establishment. We also evaluate the applicability of the primitive representation method to imitation learning and motion planning algorithms. The model is trained and validated by using the driving data collected from the Beijing Institute of Technology intelligent vehicle platform. The results show that the proposed approach can find the proper segmentation and establish the motion primitive library simultaneously.

description: The asymptotics of n-point Green's function at large external momenta is obtained in the exponentiated form using the Fock-Feynman-Schwinger representation for propagators in the external field. The method is applied to gauge theories such as QCD and QED, and the Sudakov form-factor is calculated as an example in QED and meson form-factor in QCD. Nonperturbative contributions can be conveniently included, as it is demonstrated in the example of the confinement correction to the form-factor.

description: We use tunneling spectroscopy to study the evolution of few-electron spin states in parallel InAs nanowire double quantum dots (QDs) as a function of level detuning and applied magnetic field. Compared to the much more studied serial configuration, parallel coupling of the QDs to source and drain greatly expands the probing range of excited state transport. Owing to a strong confinement, we can here isolate transport involving only the very first interacting single QD orbital pair. For the (2,0)-(1,1) charge transition, with relevance for spin-based qubits, we investigate the excited (1,1) triplet, and hybridization of the (2,0) and (1,1) singlets. An applied magnetic field splits the (1,1) triplet, and due to spin-orbit induced mixing with the (2,0) singlet, we clearly resolve transport through all triplet states near the avoided singlet-triplet crossings. Transport calculations, based on a simple model with one orbital on each QD, fully replicate the experimental data. Finally, we observe an expected mirrored symmetry between the 1-2 and 2-3 electron transitions resulting from the two-fold spin degeneracy of the orbitals.
