description: This paper proposes a numerical model of the network of two-Chinese-character compound words (two-character network, for short). In this network, a Chinese character is a node and a two-Chinese-character compound word links two nodes. The basic framework of the model is that an important character gets many edges. As the importance of a character, we use the frequency of each character appearing in publications. The direction of edge is given according to a random number assigned to nodes. The network generated by the model is small-world and scale-free, and reproduces statistical properties in the actual two-character network quantitatively.

description: This paper introduces a novel methodology that combines the multi-resolution feature of the Gabor wavelet transformation (GWT) with the local interactions of the facial structures expressed through the Pseudo Hidden Markov model (PHMM). Unlike the traditional zigzag scanning method for feature extraction a continuous scanning method from top-left corner to right then top-down and right to left and so on until right-bottom of the image i.e. a spiral scanning technique has been proposed for better feature selection. Unlike traditional HMMs, the proposed PHMM does not perform the state conditional independence of the visible observation sequence assumption. This is achieved via the concept of local structures introduced by the PHMM used to extract facial bands and automatically select the most informative features of a face image. Thus, the long-range dependency problem inherent to traditional HMMs has been drastically reduced. Again with the use of most informative pixels rather than the whole image makes the proposed method reasonably faster for face recognition. This method has been successfully tested on frontal face images from the ORL, FRAV2D and FERET face databases where the images vary in pose, illumination, expression, and scale. The FERET data set contains 2200 frontal face images of 200 subjects, while the FRAV2D data set consists of 1100 images of 100 subjects and the full ORL database is considered. The results reported in this application are far better than the recent and most referred systems.

description: In this paper a new evolutionary algorithm, for continuous nonlinear optimization problems, is surveyed. This method is inspired by the life of a bird, called Cuckoo. The Cuckoo Optimization Algorithm (COA) is evaluated by using the Rastrigin function. The problem is a non-linear continuous function which is used for evaluating optimization algorithms. The efficiency of the COA has been studied by obtaining optimal solution of various dimensions Rastrigin function in this paper. The mentioned function also was solved by FA and ABC algorithms. Comparing the results shows the COA has better performance than other algorithms. Application of algorithm to test function has proven its capability to deal with difficult optimization problems.

description: We investigate the possible disappearance of Mott oscillations in the scattering of bosonic nuclei at sub-barrier energies. This effect is universal and happens at a critical value of the Sommerfeld parameter. It is also found that the inclusion of the short-range nuclear interaction has a profound influence on this phenomenon. Thus we suggest that the study of this lack of Mott oscillation, which we call, ``transverse isotropy" is a potentially useful mean to study the nuclear interaction.

description: In order to reach the sensitivity required to detect gravitational waves, pulsar timing array experiments need to mitigate as much noise as possible in timing data. A dominant amount of noise is likely due to variations in the dispersion measure. To correct for such variations, we develop a statistical method inspired by the maximum likelihood estimator and optimal filtering. Our method consists of two major steps. First, the spectral index and amplitude of dispersion measure variations are measured via a time-domain spectral analysis. Second, the linear optimal filter is constructed based on the model parameters found in the first step, and is used to extract the dispersion measure variation waveforms. Compared to current existing methods, this method has better time resolution for the study of short timescale dispersion variations, and generally produces smaller errors in waveform estimations. This method can process irregularly sampled data without any interpolation because of its time-domain nature. Furthermore, it offers the possibility to interpolate or extrapolate the waveform estimation to regions where no data is available. Examples using simulated data sets are included for demonstration.

description: Voronoi tessellations of Poisson point processes are widely used for modeling many types of physical and biological systems. In this paper, we analyze simulated Poisson-Voronoi structures containing a total of 250,000,000 cells to provide topological and geometrical statistics of this important class of networks. We also report correlations between some of these topological and geometrical measures. Using these results, we are able to corroborate several conjectures regarding the properties of three-dimensional Poisson-Voronoi networks and refute others. In many cases, we provide accurate fits to these data to aid further analysis. We also demonstrate that topological measures represent powerful tools for describing cellular networks and for distinguishing among different types of networks.

description: Motion of curves and surfaces in $\R^3$ lead to nonlinear evolution equations which are often integrable. They are also intimately connected to the dynamics of spin chains in the continuum limit and integrable soliton systems through geometric and gauge symmetric connections/equivalence. Here we point out the fact that a more general situation in which the curves evolve in the presence of additional self consistent vector potentials can lead to interesting generalized spin systems with self consistent potentials or soliton equations with self consistent potentials. We obtain the general form of the evolution equations of underlying curves and report specific examples of generalized spin chains and soliton equations. These include principal chiral model and various Myrzakulov spin equations in (1+1) dimensions and their geometrically equivalent generalized nonlinear Schrödinger (NLS) family of equations, including Hirota-Maxwell-Bloch equations, all in the presence of self consistent potential fields. The associated gauge equivalent Lax pairs are also presented to confirm their integrability.

Behavioral and neuroanatomical substrates contributing to motivation in the postpartum female rat
Creators: name: Seip, Katharine M.
Publisher: name: No Publisher Supplied
Year: 2009

description: The experiments described in this dissertation characterize the unique motivational state of the postpartum female rat. To effectively protect and care for offspring (pups), postpartum females must be strongly motivated to seek out and interact with pups. A combination of place preference studies, behavioral observations, and neurobiological interventions were used to explore females’ motivational state across the postpartum period.To challenge postpartum females’ maternal motivation, Chapter 1 presented females with a choice between chambers paired with pups and highly salient cocaine. While most late postpartum females preferred cocaine, many early postpartum females retained striking preference for the pup-paired chamber. To explore whether cocaine’s incentive value changed across the postpartum period, Chapter 2 examined females’ preference for cocaine- versus saline-paired chambers. Across a broad range of drug administration parameters, postpartum females consistently expressed similar, strong preference for the cocaine-paired chamber. Surprisingly, cocaine preference was stronger in postpartum females than virgin females or males. Females’ locomotor response to pup, cocaine, and saline stimuli predicted their preference for those stimuli. Chapter 3 revealed that the length of pup exposure and nature of female-pup interactions can even affect the motivational state of females that have not given birth. Virgin females were exposed to young pups for various lengths of time and then tested for pup-paired chamber preference. Striking pup-paired chamber preference emerged even in virgin females only briefly exposed to pups, matching the preference expressed by strongly motivated postpartum females. Experiments in Chapter 4 revealed that the ventral tegmental area (VTA), a brain region critical to motivated behavior, drives the incentive value of pup but not cocaine stimuli. Postpartum and virgin females were tested for their preference for pup- or cocaine-paired chambers, respectively, after transient VTA inactivation. Pup preference was abolished by VTA inactivation and restored after recovery. Cocaine preference remained intact despite VTA function.Maternal motivation is resilient to challenge during early postpartum and is at least partially driven by exposure to pups. As the choice of other salient stimuli (e.g., cocaine) during postpartum may jeopardize maternal motivation, females’ motivation to interact proactively with pups is critical to the offsprings’ survival and viability.
An adaptive sensorimotor representation for reaching in the inferior parietal lobule of behaving monkeys
Creators: name: Karnik, Anushree
Publisher: name: No Publisher Supplied
Year: 2010

description: Primates use visual guidance in order to interact with their environment. For several decades, the inferior parietal lobule (IPL) has been known to contain neurons that respond to visual stimulation and motor behavior. While the neural activity during the reaching behavior has been shown in area 7a of IPL, reach related neural responses have never been tested in the dorsal prelunate area (DP) of IPL, which is adjacent to area 7a. Furthermore, neural response prior to the reaching movement has not been assessed in DP and area 7a. The first aim was to investigate the tuning properties of single neurons in DP and area 7a. The second aim was to assess the influence of eye position signal on reaching behavior. Third, the temporal evolution of sensorimotor transformation in area 7a and DP neurons was investigated by comparing neural signals throughout the reaching task. Lastly, cortical plasticity was tested using Fresnel prisms, which displaced the visual field by 12º in one of four directions: contralateral, ipsilateral, upwards, or downwards. Foveal and peripheral reaching tasks and reaching under perceptually distorted conditions were used. Neurons in area 7a and DP were observed to have differential tuning properties during the planning phase and the initiation of the reach, in addition to being selective for eye position and retinal visual stimulation. The response properties of the neurons in areas 7a and DP changed as the trial progressed in time. Differential preparatory and reach responses were observed during foveal and peripheral reaching. This implies that both eye position and retinal signals modulated the reach related responses. Alterations in spatial tuning of the neurons during all phases of the task were observed upon insertion of the Fresnel prisms imply that neural plasticity occurs as the cortex swiftly adapts to the mismatch between sensory input and motor output. The spatial tuning of the neurons did not merely compensate for the eye position shift implying that signals other than eye position affect the neural response during reaching. These combined results strongly support the claim that crucial aspects of sensorimotor transformation occur in areas 7a and DP.
Mechanisms of amygdala facilitated cortico-striatal plasticity
Creators: name: Popescu, Andrei Tiberiu
Publisher: name: No Publisher Supplied
Year: 2010

description: The amygdala is known to mediate the enhancing effects of emotional arousal on learning and memory. The increased firing rate of neurons in the basolateral complex of the amygdala (BLA) is believed to facilitate memory storage in various target structures, such as the striatum. Changes in the efficacy of cortical inputs to the striatum are thought to underlie motor learning and habit formation, making this pathway a perfect model to test the effects of BLA activity on synaptic plasticity and learning. My thesis provides evidence that BLA synapses have an N-methyl-D-aspartate receptor – to α-amino-5-hydroxy-3-methyl-4-isoxazole propionic acid receptor ratio higher than that of cortical synapses onto the same striatal neurons (Chapter 3). This property allows BLA inputs to facilitate the induction of heterosynaptic long term potentiation in vitro (Chapters 4 and 5). I also show that temporal coupling of BLA and striatal neurons in vivo occurs during coherent bursts of gamma activity observed in the local field potentials. Changes in the coherence of BLA-striatal gamma paralleled learning of a striatal-dependent task (Chapter 6). Together, these findings point towards a new mechanism of amygdala-facilitated learning.

description: Two correlated superconducting phases are identified in layered superconductor BaTi2(Sb1-xBix)2O (x=0.16), with the superconducting transition temperatures of TC = 6 K (the high TC phase) and 3.4 K (the low TC Phase), respectively. The 6 K superconducting phase appears firstly in the as-prepared sample and can decay into the low TC phase by exposing to ambient atmosphere for certain duration. Especially the high TC phase can reappear from the decayed sample with the low TC phase by vacuum annealing. It is also found that the CDW/SDW order occurs only with the 6 K superconducting phase. These notable features and alteration of superconductivity due to the post-processing and external pressure can be explained by the scenario of electronic phase-separation.

description: We investigate the finite temperature fermionic condensate and the expectation values of the charge and current densities for a massive fermion field in a spacetime background with an arbitrary number of toroidally compactified spatial dimensions in the presence of a non-vanishing chemical potential. Periodicity conditions along compact dimensions are taken with arbitrary phases and the presence of a constant gauge field is assumed. The latter gives rise to Aharonov-Bohm-like effects on the expectation values. They are periodic functions of magnetic fluxes enclosed by compact dimensions with the period equal to the flux quantum. The current density has nonzero components along compact dimensions only. Both low- and high-temperature asymptotics of the expectation values are studied. In particular, it has been shown that at high temperatures the current density is exponentially suppressed. This behavior is in sharp contrast with the corresponding asymptotic in the case of a scalar field, where the current density linearly grows with the temperature. The features for the models in odd dimensional spacetimes are discussed. Applications are given to cylindrical and toroidal nanotubes described within the framework of effective Dirac theory for the electronic subsystem.

The effect of brain state on rapid auditory processing in the rat
Creators: name: Hollender, Liad
Publisher: name: No Publisher Supplied
Year: 2010

description: The correct interpretation of natural sounds, such as language, depends on an individual's ability to perform rapid auditory processing (RAP) - processing of auditory stimuli that occurs on a time scale of tens of milliseconds. Indeed, individuals who exhibit deficits in RAP also demonstrate impairments in the acquisition of normal language skills. Interestingly, auditory training that is designed to engage the attention of the subject can ameliorate these deficits. Even though the physiological basis of the improvement in language skills in these individuals is currently unknown, one possible correlate could be changes in brain state that occur through training. Indeed, changes in brain state have been shown to influence neuronal responsiveness to sensory stimuli. In addition, changes in the level in alertness, or attention, are associated with changes in the degree of cortical activation. In this thesis, I explored the relationship between brain state and RAP by recording the simultaneous responses of large neuronal populations in the rat auditory cortex to temporally structured auditory stimuli. I systematically quantified the magnitude of evoked responses across different brain states, both under anesthesia and during wakefulness, and assessed the efficiency of RAP by estimating how well the type of sensory stimulus could be predicted from the population activity.First, RAP was assessed during the inactivated state. Surprisingly, even though response amplitude varies systematically with the phase of the slow oscillation, the efficiency of RAP does not. Second, RAP was examined across the different global activated and inactivated states observed under urethane anesthesia. This showed that RAP is overall more efficient in the activated state because of the ability of auditory populations to strongly respond to temporally structured stimuli. Finally, the effect of changes in the instantaneous level of activation during wakefulness on RAP was studied in chronically implanted rats, again showing that the efficiency in the processing of temporally structured stimuli increases with the level of cortical activation.Together, these results establish a significant link between cortical activation and RAP performance. This suggests that improvement in language ability after training in humans might reflect an increased ability to produce cortical activation when required.

Biasing neural activity

description: Low intensity electric fields have been suggested to affect ongoing neuronal activity in both in vitro studies and in human studies. However, the physiological mechanism of how weak electrical fields affect and interact with intact brain activity is not well understood. I performed in vivo extracellular and intracellular recordings from the neocortex of anesthetized rats and extracellular recordings in behaving rats. Electric fields were generated by sinusoid patterns at slow frequency (0.7, 0.8, 1.25 or 1.7 Hz) via electrodes placed on the surface of the skull or the dura. Transcranial electric stimulation (TES) reliably entrained neurons directly in widespread cortical areas, including the hippocampus. The percentage of TES phase-locked neurons increased with stimulus intensity and depended on the behavioral state of the animal. TES-induced voltage gradient, as low as 1 mV/mm at the recording site, was sufficient to phase-bias neuronal spiking. TES-induced effects were rapid to evolve and disappeared quickly after TES-offset. Intracellular recordings showed that both subthreshold and spiking activity of neurons were under the combined influence of TES forced fields and network activity. Our findings suggest that TES in chronic preparations may be used for experimental and therapeutic control of brain activity.

description: Recent experimental data have demonstrated that $^{76}$Ge may be a rare example of a nucleus exhibiting rigid $γ$-deformation in the low-spin regime. In the present work, the experimental analysis is supported by microscopic calculations using the multi-quasiparticle triaxial projected shell model (TPSM) approach. It is shown that to best describe the data of both yrast and $γ$-vibrational bands in $^{76}$Ge, a rigid-triaxial deformation parameter $γ\approx 30^\circ$ is required. TPSM calculations are discussed in conjunction with the experimental observations and also with the published results from the spherical shell model. The occurrence of a $γγ$-band in $^{76}$Ge is predicted with the bandhead at an excitation energy of $ \sim$ 2.5 MeV. We have also performed TPSM study for the neighboring Ge- and Se-isotopes and the distinct $γ$-soft feature in these nuclei is shown to result from configuration mixing of the ground-state with multi-quasiparticle states.

description: In this paper, we focus on testing gravity theories in the radiative regime using pulsar timing array observations. After reviewing current techniques to measure the dispersion and alternative polarization of gravitational waves, we extend the framework to the most general situations, where the combinations of a massive graviton and alternative polarization modes are considered. The atlas of the Hellings-Downs functions is completed by the new calculations for these dispersive alternative polarization modes. We find that each mode and corresponding graviton mass introduce characteristic features in the Hellings-Downs function. Thus, in principal, we can not only detect each polarization mode, measure the corresponding graviton mass, but also discriminate the different scenarios. In this way, we can test gravity theories in the radiative regime in a generalized fashion, and such method is a direct experiment, where one can address the gauge symmetry of the gravity theories in their linearised limits. Although current pulsar timing still lacks enough stable pulsars and sensitivity for such practices, we expect that future telescopes with larger collecting area could make such experiments be feasible.

Auditory cortical activity in synchronized and desynchronized states
Creators: name: Marguet, Stephan
Publisher: name: No Publisher Supplied
Year: 2010

description: Cortical information processing depends critically on an animal’s brain state. Previous research has revealed there is a great deal of variability in cortical responses to repeated stimuli. This thesis addresses the question of whether activity and response variability in rat auditory cortex depends on brain state. Specifically, we hypothesized that both spontaneous and evoked activity differ between states; furthermore that cortical responses in higher-frequency “desynchronized” EEG states would be less variable and follow sensory input up to higher temporal modulation frequencies. We first assessed the spontaneous activity of auditory cortex during silence. During synchronized “slow wave” EEG states the spike counts of individual neurons in sequential time bins were irregular, but this irregular firing was coordinated across the neural population. Spike counts were more regular following a tail pinch-induced shift to higher-frequency EEG, and the population-wide coordination disappeared. We also uncovered a set of high-firing neurons with independent, rhythmic activity during desynchronized states, peaking between 8 to 18 Hz. Next we characterized responses to loud single-click stimuli. Many neurons discharged short-latency spikes with similar latency across states. These preserved spike latencies manifested as brief, sub-50ms population sequences of activity with similar profiles in different brain states. In some experiments we observed late, long-lasting effect of clicks on firing rates in synchronized states. In our last study, we show that evoked local field potentials (LFPs) can follow high-frequency amplitude modulations of broadband noise during desynchronized regimes. Spikes also track input more reliably and can be better predicted from stimuli in desynchronized states than in slow-wave states. Finally, we address whether LFPs reliably predict neural activity, and show that in most cases LFPs explain more spiking variability than our amplitude-modulated white noise stimuli. Thus much ‘noise’ in neural responses is not cell-specific, but reflects a source shared across many cells; such variability is state-dependent, and can be accounted for by LFP dynamics. Our first studies demonstrate that despite clear changes in spontaneous activity, strong onset responses to discrete broadband stimuli are often preserved across states. The final study suggests the desynchronized state supports improved representation of temporally modulated stimuli in auditory cortex.
The functional anatomy of hippocampal theta and gamma oscillations

Publisher: name: No Publisher Supplied
Year: 2009

description: This dissertation investigated how theta (4-10Hz) and gamma (40-100Hz) oscillations are coordinated across different hippocampal subnetworks during different behaviors. Using 96-site silicon probes to simultaneously record local field potentials (LFPs) and unit activity from dendritic and somatic layers of the dentate gyrus, CA3 and CA1 regions, I examined how local field potentials (LFPs) and unit activity changed the theta and gamma synchronization of hippocampal networks as a function of behavior. Specifically, I compared hippocampal activity of rats during performance of a hippocampus-dependent delayed spatial alternation task on a modified T-maze versus performance of non-mnemonic control tasks. I also compared hippocampal network activity during active waking behavior versus rapid eye movement (REM) sleep.The first study examined how theta oscillations throughout the hippocampal subnetworks change during behavioral task performance. Although theta oscillations were generally highly coherent throughout the system, I found that the power, coherence and phase of theta oscillations fluctuated in a layer-specific manner, suggesting the presence of multiple interdependent dipoles. I also found layer-specific changes in theta power and coherence during different portions of both alternation and control tasks, as well as a decreased phase lag between CA3 and CA1 theta oscillations on the center arm of the T-maze compared to other segments of the alternation and control tasks.The second study examined changes in hippocampal gamma oscillations during performance of the alternation and control tasks. This study found that on the center arm of the T-maze, the power and coherence of gamma oscillations at the CA3-CA1 interface increased compared to other segments in the alternation task or compared to control task segments.The third study examined changes in theta and gamma coordination of hippocampal networks during active waking versus REM sleep. I found increased dentate/CA3 theta and gamma synchrony, but decreased CA3-CA1 gamma coordination during REM sleep. I also detected phasic bursts of LFP power in the dentate molecular layer that divided REM sleep into phasic and tonic periods. Although tonic periods characterized the majority of REM sleep epochs (~95%), phasic periods exhibited transient increases in theta and gamma coordination among all of the hippocampal subregions.

description: In this Letter, we explore the hypothesis that the smooth appearance of bow shocks around some red supergiants (RSGs) might be caused by the ionization of their winds by external sources of radiation. Our numerical simulations of the bow shock generated by IRC-10414 (the first-ever RSG with an optically detected bow shock) show that the ionization of the wind results in its acceleration by a factor of two, which reduces the difference between the wind and space velocities of the star and makes the contact discontinuity of the bow shock stable for a range of stellar space velocities and mass-loss rates. Our best fit model reproduces the overall shape and surface brightness of the observed bow shock and suggests that the space velocity and mass-loss rate of IRC-10414 are $\approx$50 ${\rm km} \, {\rm s}^{-1}$ and $\approx$$10^{-6}$ $M_\odot \, {\rm yr}^{-1}$, respectively, and that the number density of the local ISM is $\approx$3 ${\rm cm}^{-3}$. It also shows that the bow shock emission comes mainly from the shocked stellar wind. This naturally explains the enhanced nitrogen abundance in the line-emitting material, derived from the spectroscopy of the bow shock. We found that photoionized bow shocks are $\approx$15$-$50 times brighter in optical line emission than their neutral counterparts, from which we conclude that the bow shock of IRC-10414 must be photoionized.

description: The temporal behaviour of solar active longitudes has been examined by using two sunspot catalogues, the Greenwich Photoheliographic Results (GPR) and the Debrecen Photoheliographic Data (DPD). The time-longitude diagrams of the activity distribution reveal the preferred longitudinal zones and their migration with respect to the Carrington frame. The migration paths outline a set of patterns in which the activity zone has alternating prograde/retrograde angular velocities with respect to the Carrington rotation rate. The time profiles of these variations can be described by a set of successive parabolae. Two similar migration paths have been selected from these datasets, one northern path during cycles 21 - 22 and one southern path during cycles 13 - 14, for closer examination and comparison of their dynamical behaviours. The rates of sunspot emergence exhibited in both migration paths similar periodicities, close to 1.3 years. This behaviour may imply that the active longitude is connected to the bottom of convection zone.
Low angular momentum flow model II for Sgr A*

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We examine 1D two-temperature accretion flows around a supermassive black hole, adopting the specific angular momentum λ, the total specific energy εand the input accretion rate \dot M_{input} = 4.0x10^{-6} solar mass/yr estimated in the recent analysis of stellar wind of nearby stars around Sgr A*. The two-temperature flow is almost adiabatic even if we take account of the heating of electrons by ions, the bremsstrahlung cooling and the synchrotron cooling, as long as the ratio βof the magnetic energy density to the thermal energy density is taken to be as β< 1. The different temperatures of ions and electrons are caused by the different adiabatic indices of ions and electrons which depend on their temperature states under the relativistic regime. The total luminosity increases with increasing βand results in - 10^{35} - 10^{36} erg/s for β=10^{-3} - 1. Furthermore, from 2D time-dependent hydrodynamical calculations of the above flow, we find that the irregularly oscillating shocks are formed in the inner region and that the luminosity and the mass-outflow rate vary by a factor of 2 -- 3 and 1.5 -- 4, respectively. The time variability may be relevant to the flare activity of Sgr A*.

Isolated massive stars in the Galactic center: The dynamic contribution from the Arches and Quintuplet star clusters

description: Recently, more than 100 Wolf-Rayet and OB stars were identified in the Galactic center. About a third of these sources are not spatially associated with any of the known star clusters in this region. We probe the distribution of drifted sources in numerical models of the massive clusters in the Galactic center and compare it to the observed distribution of isolated massive sources in this region. We find that stars as massive as 100 Msun drift away from the center of each cluster by up to ~60 pc using the cluster models. Our best model reproduces ~60% of the known isolated massive stars out to 80 pc from the center of the Arches cluster. This number increases to 70%-80% when we only consider the region of ~20 pc from the Arches cluster.

description: `Conspiracy' between the dark and the baryonic mater prohibits an unambiguous decomposition of disc galaxy rotation curves into the corresponding components. Several methods have been proposed to counter this difficulty, but their results are widely discrepant. In this paper, I revisit one of these methods, which relies on the relation between the halo density and the decrease of the bar pattern speed. The latter is routinely characterised by the ratio ${\cal R}$ of the corotation radius $R_{CR}$ to the bar length $L_b$, ${\cal R}=R_{CR}/L_b$. I use a set of $N$-body+SPH simulations, including sub-grid physics, whose initial conditions cover a range of gas fractions and halo shapes. The models, by construction, have roughly the same azimuthally averaged circular velocity curve and halo density and they are all submaximal, i.e. according to previous works they are expected to have all roughly the same ${\cal R}$ value, well outside the fast bar range (1.2 $\pm$ 0.2). Contrary to these expectations, however, these simulations end up having widely different ${\cal R}$ values, either within the fast bar range, or well outside it. This shows that the ${\cal R}$ value can not constrain the halo density, nor determine whether galactic discs are maximal or submaximal. I argue that this is true even for early type discs (S0s and Sas).
