description: We present a detailed X-ray study of the intracluster medium (ICM) of the nearby, cool-core galaxy cluster Abell 478, with Chandra and XMM observations. Using a wavelet smoothing hardness analysis, we derive detailed temperature maps of A478, revealing a surprising amount of temperature structure. The broad band Chandra spectral fits yield temperatures which are significantly hotter than those from XMM, but the Fe ionization temperature shows good agreement. We show that the temperature discrepancy is slightly reduced when comparing spectra from regions selected to enclose nearly isothermal gas. However, by simulating multi-temperature spectra and fitting them with a single temperature model, we find no significant difference between Chandra and XMM, indicating that non-isothermality cannot fully explain the discrepancy. We have discovered 4 hot spots located between 30--50 kpc from the cluster center, where the gas temperature is roughly a factor of 2 higher than in the surrounding material. We estimate the combined excess thermal energy present in these hot spots to be (3+/-1)x10^59 erg. The location of and amount of excess energy present in the hot spots are suggestive of a common origin within the cluster core, which hosts an active galactic nucleus. This cluster also possesses a pair of X-ray cavities coincident with weak radio lobes, as reported in a previous analysis, with an associated energy <10% of the thermal excess in the hot spots. The presence of these hot spots could indicate strong-shock heating of the ICM from the central radio source -- one of the first such detections in a cool core cluster. We also probe the mass distribution in the core and find it to be characterized by a logarithmic slope of -0.35+/-0.22, which is significantly flatter than an NFW cusp of -1. (abridged)

description: An experimental study, that finds the impact of Internet access control on the employees productivity in the National University. The purpose of the study is to boost the employee productivity through proper Internet access control. The main objectives are to find the most used web categories by the staff, find if relation exists between productivity and none work related internet usage, and choose the best level of Internet access control. Before initiating the experiment, Employees Internet usage was monitored and accordingly classified them into the proper Internet access control groups. Then supervisors were asked for a pre-test productivity measures for their staff, after that the experiment was initiated for 45 days. Then, a post-test productivity measure was done. Productivity changes were analyzed with the department nature, its Internet usage portfolio and its current Internet access control group; then the best level of restriction was found. The result showed that the productivity of departments with low Internet usage was not affected by restricting and none restricting Internet access. However, for high Internet usage departments noticeable productivity improvement was there when the Internet restriction policy was not affecting work-related websites; but when it was affecting work-related websites the productivity decreased.

description: Using 281 pb^-1 of data collected with the CLEO-c detector, we report on first observations and new measurements of Cabibbo-suppressed decays of D mesons to 2, 3, 4, and 5 pions. Branching fractions of previously unobserved modes are measured to be: B(D^0\to pi^+pi^-pi^0pi^0)=(9.9\pm0.6\pm0.7\pm0.2\pm0.1)x10^-3, B(D^0\toπ^+π^+π^-π^-π^0)=(4.1\pm0.5\pm0.2\pm0.1\pm0.0)x10^-3, B(D^+\toπ^+π^0π^0)=(4.8\pm0.3\pm0.3\pm0.2)x10^-3, B(D^+\toπ^+π^+π^-π^0)=(11.6\pm0.4\pm0.6\pm0.4)x10^-3, B(D^0\toηπ^0)=(0.62\pm0.14\pm0.05\pm0.01\pm0.01)x10^-3, and B(D^0\toωπ^+π^-)=(1.7\pm0.5\pm0.2\pm0.0\pm0.0)x10^-3. The uncertainties are from statistics, experimental systematics, normalization and CP correlations (for D^0 modes only). Improvements in other multi-pion decay modes are also presented. The D-->pi pi rates allow us to extract the ratio of isospin amplitudes A(Delta I=3/2)/A(ΔI=1/2)=0.420\pm0.014(stat)\pm0.016(syst) and the strong phase shift of delta_I=(86.4+-2.8+-3.3) degrees, which is quite large and now more precisely determined.

description: The braconid larval parasitoid Cotesia flavipes Cameron was introduced from Asia into East and Southern African region starting in 1993 to control the invasive exotic maize stemborer Chilo partellus (Swinhoe) (Lepidoptera: Crambidae). A quasi-experiment was constructed using farmers that applied sublethal dosages of pesticide in assessing the counterfactual for the impact of the establishment of the introduced parasitoid in five countries in the region. Logistic regression method was used to estimate the probability that farmers’ would inadvertently exclude parasitoids in their maize field. Thereafter the propensity score matching method was used to find corresponding farmers excluding parasitoids among those who did not for yield comparison. The geographical information system (GIS) application software with ecological, agricultural and land cover data bases was used to classify and select the ecological zones surveyed, to estimate the spread of the parasitoid. Results indicate a rampant use of pesticides at sublethal dosage across the countries. Intensifying maize production by is likely to improve the effectiveness of parasitoids. The annual value of the economic impact of the introduced parasitoid is estimated to range from US $ 43 m – 76 m. It is apparent that the appropriate matching algorithm depends on the distribution of yield data available. The study demonstrates the potential of using biological agents to improve yields among the poor households who can seldom afford purchased inputs.

description: Finite element model updating of a structure made of linear elastic materials is based on the solution of a minimization problem. The goal is to find some unknown parameters of the finite element model (elastic moduli, mass densities, constraints and boundary conditions) that minimize an objective function which evaluates the discrepancy between experimental and numerical dynamic properties. The objective function depends nonlinearly on the parameters and may have multiple local minimum points. This paper presents a numerical method able to find a global minimum point and assess its reliability. The numerical method has been tested on two simulated examples - a masonry tower and a domed temple - and validated via a generic genetic algorithm and a global sensitivity analysis tool. A real case study monitored under operational conditions has also been addressed, and the structure's experimental modal properties have been used in the model updating procedure to estimate the mechanical properties of its constituent materials.

In the latter case I mainly discuss its effect on the Higgs-sector and hence on Higgs Phenomenology at the LHC. After outlining the possibilities that a study of the $\ch_1 \nt_2$ production at the LHC might offer, I will summarise the effects of the CPV in MSSM on the Higgs searches at the LHC. Further, I will discuss how a study of the process $H^\pm \to W^+ ϕ_1$ may be able to plug a 'hole" in the $\tan β$-$\mh{+}$ plane, where the LEP has no sensitivity and where the searches in the usual discovery channels at the LHC are likely to fail as well.

description: This paper examines potential of contract farming as a rural development tool by revealing its effect on productivity and income of small holders in tea production in north-western Vietnam. In the present research, three economic analyses are applied. First, the technical efficiency of tea production is estimated by using stochastic frontier model. The results show that contract farming achieved significantly higher technical efficiency compared to non-contract farming. Second, logit model is investigated to determine the influential socio-economic characteristics of households for contract participation. The model indicates that social relationship of households, such as the membership in the communist party, play an important role in contract participation with 73% correct prediction. Finally, the impact of contract participation on income is estimated by applying Propensity Score Matching. A significant effect of contract participation on income by 8,000 VND daily per capita can be observed.

description: The scalaron of the metric $f(R)$ gravity can constitute dark matter if its mass is in the range $4\,\text{meV} \lesssim m \lesssim 1\,\text{MeV}$. We give an overview of such $f (R)$ gravity theory minimally coupled to the Standard Model. Similarly to other dark-matter models based on scalar fields, this model has the issue of initial conditions. Firstly, the initial conditions for the scalaron are to be tuned in order to produce the observed amount of dark matter. Secondly, the primordial spatial inhomogeneities in the field are to be sufficiently small because they generate entropy (or isocurvature) perturbations, which are constrained by observations. We consider these issues in the present paper. The initial conditions for the scalaron presumably emerge at the inflationary stage. We point out that the homogeneous part of the scalaron initial value is largely unpredictable because of quantum diffusion during inflation. Thus, to account for the observed amount of dark matter, one has to resort to anthropic considerations. Observational constraints on the primordial spatial inhomogeneity of the scalaron are translated into upper bounds on the energy scale of inflation, which happen to be low but not too restrictive.

description: We report on the identification of a new cluster in the far halo of the M31 galaxy. The cluster, named Bologna 514 (B514) has an integrated magnitude M_V=-8.5 +- 0.6, and a radial velocity, as estimated from two independent low-resolution spectra, V_r=-456 +- 23 km/s, which fully confirms its membership to the M31 system. The observed integrated spectrum is very similar to those of classical globular clusters. Being located at ~ 4^o (~55 kpc in projected distance) from the center of the parent galaxy, B514 is by far the most remote M31 cluster ever discovered. Its projected position, near the galaxy major axis, and M31-centric velocity, similar to that observed in the outermost regions of the HI rotation curve, may indicate that it belongs to the subsystem of M31 clusters that has been recently proposed (Morrison et al. 2004) to be part of the dynamically-cold thin disc of the galaxy.

description: With a view to understanding the ``rheochaos'' observed in recent experiments in a variety of orientable fluids, we study numerically the equations of motion of the spatiotemporal evolution of the traceless symmetric order parameter of a sheared nematogenic fluid. In particular we establish, by decisive numerical tests, that the irregular oscillatory behavior seen in a region of parameter space where the nematic is not stably flow-aligning is in fact spatiotemporal chaos. We outline the dynamical phase diagram of the model and study the route to the chaotic state. We find that spatiotemporal chaos in this system sets in via a regime of {\em spatiotemporal intermittency}, with a power-law distribution of the widths of laminar regions, as in H. Chaté and P. Manneville, Phys. Rev. Lett. {\bf 58}, 112 (1987). Further, the evolution of the histogram of band sizes shows a growing length-scale as one moves from the chaotic towards the flow aligned phase. Finally we suggest possible experiments which can observe the intriguing behaviors discussed here.

description: We introduce a quasinormal mode theory of mechanical open-cavity modes for optomechanical resonators, and demonstrate the importance of using a generalized (complex) effective mode volume and the phase of the quasinormal mode. We first generalize and fix the normal mode theories of the elastic Purcell factor, and then show a striking example of coupled quasinormal modes yielding a pronounced Fano resonance. Our theory is exemplified and confirmed by full three-dimensional calculations on optomechanical beams, but the general findings apply to a wide range of mechanical cavity modes. This quasinormal mechanical mode formalism, when also coupled with a quasinormal theory of optical cavities, offers a unified framework for describing a wide range of optomechanical structures where dissipation is an inherent part of the resonator modes.

description: The marketing kind of analysis in the domestic and international markets of Tokaj’s wine speciality has not happened yet. The present research scientific method supportedly defines the consumers of Tokaj’s wine speciality and it determinates the overlay receipt. The basis of the questionnaire research at the wine consumers cirlce is a representative sample of 1179 people. It confirms the truthfulness with factos and cluster dissection. On the hungarian market 5 sections can be devided, which has been determined by the earning category, the wine savvy and the referene price interval. TokajWine Specialities named “late vintage” are also available. This name can be confusing for the consumer, some do not understand in what they differ from other Tokaj Wine Specialities, as actually all Tokaj Wine Specialities are late vintage wines; particularly, wine is harvested later than usual, occasionally in October or November. The findings obtained during the research can be utilised in practice, too. In accordance with the results and conclusions, we have several practical suggestions. Our methodological suggestion is that the result of the cluster analysis based upon a large number of representative sample should be cross-checked with focus group tests; what is more, upon justification and verification, a detailed analysis of the given segments can also be performed better with this method. It would be worth studying the exact reasons for the popularity of wines with the name ”late vintage”. Such types of Tokaj Wine Specialities should be given higher priority in marketing terms. My suggestion is that the type of wine accepted and liked by consumers should be kept count of as TokajWine Specialities officially, too. The future marketing strategy has to be developed by knowing the sections and by it’s further research which has to integrate to the strategy of Tokaj’s wine region.

description: The topological B-model with target the supertwistor space CP(3|4) is known to describe perturbative amplitudes of N=4 Super Yang-Mills theory. We review the extension of this correspondence to the superconformal gauge theories that arise as marginal deformations of N=4 by considering the effects of turning on a certain closed string background, which results in non-anticommutativity in the fermionic directions of CP(3|4). We generalise the twistor string prescription for amplitudes to this case and illustrate it with some simple examples.

description: The thermodynamic properties of the hot plasma in galaxy clusters retains information on the processes leading to the formation and evolution of the gas in their deep, dark matter potential wells. These processes are dictated not only by gravity but also by gas physics, e.g. AGN feedback and turbulence. In this work, we study the thermodynamic properties, e.g. density, temperature, pressure, and entropy, of the most massive and the most distant ($z > 1.2$) SPT-selected clusters, and compare them with those of the nearby clusters ($z<0.1$) to constrain their evolution as a function of time and radius. We find that thermodynamic properties in the outskirts of high redshift clusters are remarkably similar to the low redshift clusters, and their evolution follows the prediction of the self-similar model. Their intrinsic scatter is larger, indicating that the physical properties that lead to the formation and virialization of cluster outskirts show evolving variance. On the other hand, thermodynamic properties in the cluster cores deviates significantly from self-similarity indicating that the processes that regulate the core are already in place in these very high redshift clusters. This result is supported by the unevolving physical scatter of all thermodynamic quantities in cluster cores.

Facets of anger : inter-relations and relations to driving behaviours
Creators: name: Young, Sandra N.
Publisher: name: University of British Columbia
Year: 2009

description: This thesis examines the relationship of anger expression with other facets of the anger construct and applies these to account for individual differences in risky driving behaviors. Anger expression as measured by the Behavioral Anger Response Questionnaire is compared to measures of hostile attitude, trait driving anger, Type-A personality, and anxiety to further evaluate the construct validity for this new measure of anger expression as it relates to anger level at large and to angry driving. Driving-related anger is then related to traffic violations and motor vehicle accidents given that anger is know to contribute to risky driving and that the resulting traffic accidents are one of the leading causes of disability and death in our society. A large sample (N = 316) of active drivers of varying ages (range = 17-67 years) filled out a questionnaire package containing measures of driving anger, hostile attitude, Type-A personality, anger expression as measured by the Behavioral Anger Response Questionnaire, demographics, and driving behaviours. Analyses were first conducted to test the nomological network of general and driving related anger variables and differentiate anger level from anger expression. Driving anger was found to be related to hostile attitude (r = .33, p<.001), anxiety (r = .29, p<.001), anger out (r = .33, p>001), and rumination (r = .24, p<.001). As for driving behaviours, more men reported receiving tickets for moving violations (X²(l) = 15.58, p<.001), and being involved in minor (X² (l) = 4.51, p<025), and major motor vehicle accidents (X² (l) = 5.95, p<.025) over the past five years, but not motor vehicle accidents overall (X² (l) = 3.56, p>.05). A greater number of participants under 30 years of age reported involvement in motor vehicle accidents as well (X² (l) = 11.77, p<.001). Next, driving anger related variables were used to test predictive models of who received tickets for moving violations and who has an accident history. After controlling for age, gender, and hours driven per week, none of the psychological variables or tested interactions of these variables with age or gender predicted the receipt of tickets for moving violations, or major motor vehicle accident involvement. The receipt of tickets for moving violations, however, along with an interaction between anger out, age and gender, predicted M V A involvement (X² (9) = 36.52, p<.001), for women under 30 years of age (odds = 1.47 for also increase in anger out).

description: Since Shor's discovery of an algorithm to factor numbers on a quantum computer in polynomial time, quantum computation has become a subject of immense interest. Unfortunately, one of the key features of quantum computers - the difficulty of describing them on classical computers - also makes it difficult to describe and understand precisely what can be done with them. A formalism describing the evolution of operators rather than states has proven extremely fruitful in understanding an important class of quantum operations. States used in error correction and certain communication protocols can be described by their stabilizer, a group of tensor products of Pauli matrices. Even this simple group structure is sufficient to allow a rich range of quantum effects, although it falls short of the full power of quantum computation.

description: Optical coherence tomography (OCT) is a non-invasive 3D modality widely used in ophthalmology for imaging the retina. Achieving automated, anatomically coherent retinal layer segmentation on OCT is important for the detection and monitoring of different retinal diseases, like Age-related Macular Disease (AMD) or Diabetic Retinopathy. However, the majority of state-of-the-art layer segmentation methods are based on purely supervised deep-learning, requiring a large amount of pixel-level annotated data that is expensive and hard to obtain. With this in mind, we introduce a semi-supervised paradigm into the retinal layer segmentation task that makes use of the information present in large-scale unlabeled datasets as well as anatomical priors. In particular, a novel fully differentiable approach is used for converting surface position regression into a pixel-wise structured segmentation, allowing to use both 1D surface and 2D layer representations in a coupled fashion to train the model. In particular, these 2D segmentations are used as anatomical factors that, together with learned style factors, compose disentangled representations used for reconstructing the input image. In parallel, we propose a set of anatomical priors to improve network training when a limited amount of labeled data is available. We demonstrate on the real-world dataset of scans with intermediate and wet-AMD that our method outperforms state-of-the-art when using our full training set, but more importantly largely exceeds state-of-the-art when it is trained with a fraction of the labeled data.

description: Western cultures support the notion that the ideal ‘professional’ behaviour for a leader is primarily rational and carefully controlled emotionally. The relationship of reason and emotion is often played out as one of mutual exclusion, and moreover as one representing hierarchy of leaders and followers. Power positions in most organizations are ritually emphasized through strict emotional control/suppression. Thus this display of unemotional rationality is held to be synonymous with control, may actually belie emotional and psychical insanities, and indicate organizational incongruities. Since, emotions play crucial role in the regulation of workplace relations. Negative emotions are the basis of awareness and positive ones are that of trust, and hence they both are needed in everyday situations. Leaders’ emotions can be used as tools to motivate and to express individualist attention and caring. However, this use of emotions as tools may come at a price for those leaders who are less apt at emotion regulation. In sum, workplace is an emotional place and it is of best interest of the organizational members, – both the leaders and those led, – to understand the leaders’ genuine and displayed emotions, their antecedents and their consequences.

description: Pressure on natural resources and the global environment have been identified as the most important challenges to maintain prosperity and improve environmental care. Agriculture is responsible for only a small proportion of carbon dioxide (CO2) emissions, but the sector is more closely associated with emissions of other greenhouse gases such as methane (CH4) and nitrous oxide (N2O). The global warming potential of agricultural activities defined as greenhouse gas (GHG) emissions in CO2 equivalents is relatively low in Hungary, when calculated per land area. However this difference decline, when a GHG emission is calculated per product unit, as yields are lower then in West European countries. Environmental load caused by agriculture is also low in Hungary, where increasing part of EU resources are used for the long-term preservation of natural resources and for the raising of awareness of sustainable farming. The strength of the environmental situation of Hungary, consist of several elements, such as the rich bio-diversity, the significant size of territories falling under natural protection, the extent and importance of forests and the low environmental load from crop production. Among the weaknesses the nitrate load of the animal husbandry farms, the increasing water and wind erosion, the soil compaction and degradation have to be taken into consideration. Climate change has high risk potential and the mitigation activities of the New Hungary Rural Development Programme (HRDP) are investigated in this paper with the aim to increase mitigation activities in rural area and reduce the causes of climate change.
History of ARIES: A premier research institute in the area of observational sciences

Subjects: subject: Instrumentation and Methods for Astrophysics (astro-ph.IM)
subject: FOS: Physical sciences

description: The Aryabhatta Research Institute of Observational Sciences (ARIES), a premier autonomous research institute under the Department of Science and Technology, Government of India has a legacy of about seven decades with contributions made in the field of observational sciences namely atmospheric and astrophysics. The Survey of India used a location at ARIES, determined with an accuracy of better than 10 meters on a world datum through institute participation in a global network of Earth artificial satellites imaging during late 1950. Taking advantage of its high-altitude location, ARIES, for the first time, provided valuable input for climate change studies by long term characterization of physical and chemical properties of aerosols and trace gases in the central Himalayan regions. In astrophysical sciences, the institute has contributed precise and sometime unique observations of the celestial bodies leading to a number of discoveries. With the installation of the 3.6 meter Devasthal optical telescope in the year 2015, India became the only Asian country to join those few nations of the world who are hosting 4 meter class optical telescopes. This telescope, having advantage of geographical location, is well-suited for multi-wavelength observations and for sub-arc-second resolution imaging of the celestial objects including follow-up of the GMRT, AstroSat and gravitational-wave sources.

description: The observation of gravitational waves from an asymmetric binary opens the possibility for heavy neutron stars, but these pose challenges to models of the neutron star equation of state. We construct heavy neutron stars by introducing non-trivial structure in the speed of sound sourced by deconfined QCD matter, which cannot be well recovered by spectral representations. Their moment of inertia, Love number and quadrupole moment are very small, so a tenfold increase in sensitivity may be needed to test this possibility with gravitational waves, which is feasible with third generation detectors.

EFFECT OF UNCERTAINTY ON FARMERS DECISION MAKING: CASE OF ANIMAL MANURE USE

description: The negative effects of uncertainty and on perceived absorptive capacity indicates that identified problems with respect to the use of animal manures do not motivate farmers to search for external knowledge in order to solve these problems but, in contrary, they will be less inclined to learn about better ways to make use of manure. Furthermore, this will make them also less satisfied about the external knowledge which is offered and particularly will make them less willing to invest in soil analysis techniques which could help them to develop a more reliable nutrient management. These conclusions are problematic for policy makers, counsellors and consultants. First of all, while uncertainty could lead to problem identification and start a learning process in some contexts, it might discourage all learning in others, such as in the case of manure use. Policy makers should be aware that uncertainty following policy changes might lead to diminishing capacity of farmers to adapt to these changes and eventually lead to undesired effects of the measure. Second, while extension is the main instrument to help farmers adapt to the changing production environment, farmers with low absorptive capacity – being the main target group for these actions – will be less open towards these extension activities. This shows that more policy attention should be devoted to enhancing the learning skills and openness towards external knowledge.

description: We present the results of recent Arecibo and Green Bank observations of the globular cluster NGC 6760. Using Arecibo, a phase-coherent timing solution has been obtained for the previously known binary pulsar in this cluster, PSR J1911+0102A. We have also discovered a new millisecond pulsar in NGC 6760, PSR J1911+0101B, an isolated object with a rotational period of 5.38 ms and a dispersion measure DM = 196.7 cm-3 pc. Both pulsars are located within 1.3 core radii of the cluster center and have negative period derivatives. The resulting lower limits for the accelerations of the pulsars are within the range expected given a simple model of the cluster. A search for eclipses in the PSR J1911+0102A binary system using both telescopes yielded negative results. The corresponding limits on the extra gas column density at superior conjunction are consistent with the hypothesis that the observational properties of ultra-low-mass binary pulsars like PSR J1911+0102A are strongly affected by the inclination of the orbital plane of the system. Among globular cluster pulsar populations, that of NGC 6760 exhibits one of the largest known spreads in DM. This quantity seems to be roughly proportional to a cluster's central DM; this suggests that the observed spread is caused by a turbulent interstellar medium at spatial scales of 1 pc.

Mother-son interactions in families of children with attention-deficit/hyperactivity disorder
Creators: name: Seipp, Carla Marguerite
Publisher: name: University of British Columbia
Year: 2009

description: This study compares a general pattern or style of parenting behaviors, termed responsiveness, in mothers of sons with comorbid Attention-Deficit/Hyperactivity Disorder (ADHD) and Oppositional Defiant Disorder (ODD), mothers of sons with ADHD only, and mothers of nonproblem sons. Participants include 87 mothers with sons ranging in age from 7 to 9 years. Twenty-five sons were in the comorbid ADHD and ODD group, 24 in the ADHD group, and 38 had no behavioral difficulties. Mothers were videotaped in a small laboratory room while playing with their sons and engaging in a clean up task with them. Maternal responsiveness was assessed using a previously developed observational coding protocol. Mothers of sons with comorbid ADHD and ODD were found to be significantly less responsive than mothers of nonproblem control sons. However, mothers of sons with only ADHD were neither significantly less responsive than mothers of nonproblem sons, nor significantly more responsive than mothers of sons with ADHD and ODD. This study replicated previous findings of mothers using more positive affective tone and being more involved in the free play compared to the clean up condition, offering further validation for the maternal responsiveness coding protocol. This study builds upon existing literature finding greater disruption in parenting behavior in families of children with ADHD and ODD compared to families of nonproblem children. The results of this study highlight the importance of distinguishing families of children with ADHD and ODD from families of children with ADHD only, particularly when examining parenting variables. The findings of this study offer some support for the clinical utility of including responsiveness training as a component of parent training interventions for ODD in children with ADHD.

description: An ideal atomistic model of a disordered material should contradict no experiments,and should also be consistent with accurate force fields (either {\it ab initio}or empirical). We make significant progress toward jointly satisfying {\it both} of these criteria using a hybrid reverse Monte Carlo approach in conjunction with approximate first principles molecular dynamics. We illustrate the method by studying the complex binary glassy material g-GeSe$_2$. By constraining the model to agree with partial structure factors and {\it ab initio} simulation, we obtain a 647-atom model in close agreement with experiment, including the first sharp diffraction peak in the static structure factor. We compute the electronic state densities and compare to photoelectron spectroscopies. The approach is general and flexible.
