description: Many state-of-the-art signal decomposition techniques rely on a low-rank factorization of a time-frequency (t-f) transform. In particular, nonnegative matrix factorization (NMF) of the spectrogram has been considered in many audio applications. This is an analysis approach in the sense that the factorization is applied to the squared magnitude of the analysis coefficients returned by the t-f transform. In this paper we instead propose a synthesis approach, where low-rankness is imposed to the synthesis coefficients of the data signal over a given t-f dictionary (such as a Gabor frame). As such we offer a novel modeling paradigm that bridges t-f synthesis modeling and traditional analysis-based NMF approaches. The proposed generative model allows in turn to design more sophisticated multi-layer representations that can efficiently capture diverse forms of structure. Additionally, the generative modeling allows to exploit t-f low-rankness for compressive sensing. We present efficient iterative shrinkage algorithms to perform estimation in the proposed models and illustrate the capabilities of the new modeling paradigm over audio signal processing examples.

description: We demonstrate that low resolution CaII triplet (CaT) spectroscopic estimates of the overall metallicity ([Fe/H]) of individual Red Giant Branch (RGB) stars in two nearby dwarf spheroidal galaxies (dSphs) agree to +-0.1-0.2 dex with detailed high resolution spectroscopic determinations for the same stars over the range -2.5 < [Fe/H] < -0.5. For this study we used a sample of 129 stars observed in low and high resolution mode with VLT/FLAMES in the Sculptor and Fornax dSphs. We also present the data reduction steps we used in our low resolution analysis and show that the typical accuracy of our velocity and CaT [Fe/H] measurement is ~2 km/s and 0.1 dex respectively. We conclude that CaT-[Fe/H] relations calibrated on globular clusters can be applied with confidence to RGB stars in composite stellar populations over the range -2.5 < [Fe/H] < -0.5.

description: We define the functionality of delegated pseudo-secret random qubit generator (PSRQG), where a classical client can instruct the preparation of a sequence of random qubits at some distant party. Their classical description is (computationally) unknown to any other party (including the distant party preparing them) but known to the client. We emphasize the unique feature that no quantum communication is required to implement PSRQG. This enables classical clients to perform a class of quantum communication protocols with only a public classical channel with a quantum server. A key such example is the delegated universal blind quantum computing. Using our functionality one could achieve a purely classical-client computational secure verifiable delegated universal quantum computing (also referred to as verifiable blind quantum computation). We give a concrete protocol (QFactory) implementing PSRQG, using the Learning-With-Errors problem to construct a trapdoor one-way function with certain desired properties (quantum-safe, two-regular, collision-resistant). We then prove the security in the Quantum-Honest-But-Curious setting and briefly discuss the extension to the malicious case.

A Complicated Bovine Uterine Torsion

description: A seven-year-old pluriparturient Holstein cow was presented because of failure to complete parturition. On physical examination a 270-degree, counterclockwise uterine torsion was found. Attempts to correct the torsion via the vagina were unsuccessful as the fetus would immediately return to the dorso-ileal position when released. A left flank laparotomy was performed and the 270- degree counterclockwise torsion was confirmed. One hind limb has perforated the uterine wall and was the cause of failed attempts to correct the torsion vaginally. The live term, male fetus was delivered by cesarean section. The uterus and body wall were routinely closed and the cow was treated for shock. She died 12 hours post-operatively.

Humor-Centered Design: Using Humor as a Rhetorical Approach in Design
Creators: name: Delaney, Chelsey
Publisher: name: Carnegie Mellon University
Year: 2011
Subjects: Design

description: My thesis pursues the development of a tool to empower designers and non-designers to better understand humor’s function in design and to encourage the use of humor as a rhetorical device to undertake social problems. Humor research is a field that is largely based on linguistic studies, but because of its multidisciplinary stretch in the past decade has displayed a broad rhetorical influence; however, it has yet to form a substantial relationship with design. Through a literature review of linguistic, rhetorical, and design theories, I identified a set of heuristics that guide how humor should operate in design. I then tested the effectiveness of the heuristics, and with their final revision, applied them to designing for motivational problems associated with public displays of political mobilization. My user research inferred the creation of a mobile instructional tool that guides the collaborative and/or individual production of political communication artifacts (e.g. rally signs), which use humor to confront socially complex issues. The artifacts’ implicit intent is to motivate political mobilization and to found and/or empower communities. My project focus entails the creation and testing of the tool on the individual level. Whether the artifacts created produce the desired effect regarding mobilization and community strength is unknown; Future work should lend itself to testing humorous design’s effect on political mobilization and ability to empower communities.
Chemical composition of A and F dwarf members of the Coma Berenices open cluster

description: Abundances of 18 chemical elements have been derived for 11 A (normal and Am) and 11 F dwarfs members of the Coma Berenices open cluster in order to set constraints on evolutionary models including transport processes (radiative and turbulent diffusion)calculated with the Montreal code. A spectral synthesis iterative procedure has been applied to derive the abundances from selected high quality lines in high resolution high signal-to-noise echelle spectra obtained with ELODIE at the Observatoire de Haute Provence. The chemical pattern found for the A and F dwarfs in Coma Berenices is reminiscent of that found in the Hyades and the UMa moving group. In graphs representing the abundances [X/H] versus the effective temperature, the A stars often display abundances much more scattered around their mean values than the F stars do. Large star-to-star variations are detected for A stars in their abundances which we interpret as evidence of transport processes competing with radiative diffusion. The F stars have solar abundances for almost all elements except for Mg, Si, V and Ba. The derived abundances patterns, [X/H] versus atomic number, for the slow rotator HD108642 (A2m) and the moderately fast rotator HD106887 (A4m) were compared to the predictions of self consistent evolutionary model codes including radiative and different amounts of turbulent diffusion. None of the models reproduces entirely the overall shape of the abundance pattern. While part of the discrepancies between derived and predicted abundances may be accounted for by non-LTE effects, the inclusion of competing processes such as rotational mixing in the radiative zones of these stars seems necessary to improve the agreement between observed and predicted abundance patterns.

description: Electro-optic modulation, the imprinting of a radio-frequency (RF) waveform on an optical carrier, is one of the most important photonics functions, being crucial for high-bandwidth signal generation, optical switching, waveform shaping, data communications, ultrafast measurements, sampling, timing and ranging, and RF photonics. Although silicon (Si) photonic electro-optic modulators (EOMs) can be fabricated using wafer-scale technology compatible with the semiconductor industry, such devices do not exceed an electrical 3-dB bandwidth of about 50 GHz, whereas many applications require higher RF frequencies. Bulk Lithium Niobate (LN) and etched LN modulators can scale to higher bandwidths, but are not integrated with the Si photonics fabrication process adopted widely over the last decade. As an alternative, an ultra-high-bandwidth Mach-Zehnder EOM based on Si photonics is shown, made using conventional lithography and wafer-scale fabrication, bonded to an unpatterned LN thin film. This hybrid LN-Si MZM achieves beyond 100 GHz 3-dB electrical bandwidth. Our design integrates silicon photonics light input/output and optical components, including directional couplers, low-radius bends, and path-length difference segments, realized in a foundry Si photonics process. The use of a simple low-temperature (200C) back-end integration process to bond a postage-stamp-sized piece of LN where desired, and achieving light routing into and out of LN to harness its electro-optic property without any etching or patterning of the LN film, may be broadly-useful strategies for advanced integrated opto-electronic microchips.

description: Serverless computing or function-as-a-service (FaaS) provides a way to write applications composed of scalable and manageable independent tasks communicating seamlessly without developer involvement. Strict performance guarantees or service-level agreements (SLAs) provided by cloud vendors demand predictable performance of serverless applications. Performance predictability in a datacenter environment suffers due to contention for hardware resources. In this study, we evaluate the effects of contention on two FaaS platforms; AWS Lambda, an industry leader in serverless, and the open-source OpenFaaS serverless stack. We develop a complete set of microbenchmarks as well as end-to-end applications composed of multiple functions as a benchmark suite to facilitate our study. We quantify baseline system costs of these applications across both stacks given traditional orchestration mechanisms in an isolated system. We also quantify the same with co-located workloads in datacenter-like setting with Kubernetes orchestration. We show, via experiments, that significant performance slack exists at low to moderate loads and we can intelligently colocate workloads to maximize hardware utilization while still meeting QoS target latencies. Finally, we present a contention-aware static scheduling solution for FaaS platforms with predictable performance and compare it to static versions of baseline related works. We find that an intelligent FaaS orchestrator can be based along similar lines (similar hardware-level features) as a microservices one.
Supporting Learner Social Relationships with Enculturated Pedagogal Agents
Creators: name: Ogan, Amy
Publisher: name: Carnegie Mellon University
Year: 2011
Subjects: Applied Computer Science

description: Embodied conversational agents put a “human” touch on intelligent tutoring systems by using conversation to support learning. When considering instruction in interpersonal domains, such as intercultural negotiation, the development of an interpersonal relationship with one’s pedagogical agent may play a significant role in learning. However, there is conflicting evidence in the literature both regarding the ability of agents to cultivate social relationships with humans, and their effect on learning. In this dissertation, I present a model of social dialog designed to affect learners’ interpersonal relations with virtual agents, a development process for creating social dialog, and empirical studies showing that this dialog has significant effects on learners’ perceptions of the agents and negotiation performance. In early work, I explicitly prompted learners to have social goals for the interaction. I found that while students who reported social goals for interacting with the agents had significantly higher learning gains, explicit prompting was not effective at inducing these goals. I thus focused on implicit influence of learner goals, developing a model of social instructional dialog (SID) that integrates conversational strategies that are theorized to produce interpersonal effects on relationships. In two subsequent studies, an agent with the SID model engendered greater feelings of entitativity, shared perspective, and trust, suggesting that the model improved learner social relationships with the agent. Importantly, these effects transferred to other agents encountered later in the environment. The social dialog condition also made fewer errors and achieved more negotiation objectives in a subsequent negotiation than a control group, evidence that the improved social relationship lead to better negotiation performance. These findings regarding interpersonal relationships with agents contribute to the literature on learner-agent interactions, and can guide the future development of agents in social environments.

description: The Fitch Site designated AZ:U:9:1 (ASU), is a Classic Period site of the Hohokam chronology. It is situated just north of Mesa, Arizona, on the second south terrace of the Salt River. The significance of the site to our knowledge of the Classic Period is in the fact that it is a small site consisting of a habitation structure with three rooms and connecting walls, the whole forming a compound unit. The emphasis of former research in this area had been on large sites such as Los Muertos and Pueblo Grande, with the result that the criteria for defining the Classic Period are based on the characteristics found in such sites. However, every large center with a compound-enclosed house mound was surrounded by numerous small villages. The latter has remained relatively unknown until the present.
Optimality of 1-norm regularization among weighted 1-norms for sparse recovery: a case study on how to find optimal regularizations

description: The 1-norm was proven to be a good convex regularizer for the recovery of sparse vectors from under-determined linear measurements. It has been shown that with an appropriate measurement operator, a number of measurements of the order of the sparsity of the signal (up to log factors) is sufficient for stable and robust recovery. More recently, it has been shown that such recovery results can be generalized to more general low-dimensional model sets and (convex) regularizers. These results lead to the following question: to recover a given low-dimensional model set from linear measurements, what is the "best" convex regularizer? To approach this problem, we propose a general framework to define several notions of "best regularizer" with respect to a low-dimensional model. We show in the minimal case of sparse recovery in dimension 3 that the 1-norm is optimal for these notions. However, generalization of such results to the n-dimensional case seems out of reach. To tackle this problem, we propose looser notions of best regularizer and show that the 1-norm is optimal among weighted 1-norms for sparse recovery within this framework.

description: The structural properties of strongly coupled ions in dense plasmas with moderately to strongly degenerate electrons are investigated in the framework of the one-component plasma model of ions interacting through a screened pair interaction potential. Special focus is put on the description of the electronic screening in the Singwi-Tosi-Land-Sjoelander (STLS) approximation. Different crosschecks and analyses using ion potentials obtained from ground-state quantum Monte Carlo data, the random phase approximation (RPA), and existing analytical models are presented for the computation of the structural properties, such as the pair distribution and the static structure factor, of strongly coupled ions. The results are highly sensitive to the features of the screened pair interaction potential. This effect is particularly visible in the static structure factor. The applicability range of the screened potential computed from STLS is identified in terms of density and temperature of the electrons. It is demonstrated that at r_s > 1, where rs is the ratio of the mean inter-electronic distance to the Bohr radius, electronic correlations beyond RPA have a non-negligible effect on the structural properties. Additionally, the applicability of the hypernetted chain approximation for the calculation of the structural properties using the screened pair interaction potential is analyzed employing the effective coupling parameter approach.
A method for extracting maximum resolution power spectra from microwave sky maps
Creators: name: Tegmark, Max
Publisher: name: arXiv
Year: 1994
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: A method for extracting maximal resolution power spectra from microwave sky maps is presented and applied to the 2 year COBE data, yielding a power spectrum that is consistent with a standard n=1, Q=20 micro-Kelvin model. By using weight functions that fall off smoothly near the galactic cut, it is found that the spectral resolution Δl can be more than doubled at l=15 and more than tripled at l=20 compared to simply using galaxy-cut spherical harmonics. For a future high-resolution experiment with reasonable sky coverage, the resolution around the CDM Doppler peaks would be enhanced by a factor of about 100, down to Δl\approx 1, thus allowing spectral features such as the locations of the peaks to be determined with great accuracy. The reason that the improvement is so large is basically that functions with a sharp edge at the galaxy cut exhibit considerable "ringing" in the Fourier domain, whereas smooth functions do not. The method presented here is applicable to any survey geometry, chopping strategy and exposure pattern whatsoever. The so called signal-to-noise eigenfunction technique is found to be a special case, corresponding to ignoring the width of the window functions.

description: Abstract

The purpose of this study is to investigate the effect of the Management Control System (MCS) on the performance of SMEs. The study was conducted on local restaurant SMEs managers in Tangerang, Indonesia. The number of respondents in this study was 129 local restaurant managers. This study uses the Levers of Control framework introduced by Simon (1995), namely beliefs systems, boundary systems, diagnostic control systems, and interactive control systems, as MCS variables. This study uses a structural equation model as an analytical tool and STATA software to process data using a questionnaire as a research instrument. The results showed that belief systems had no significant effect on performance SMEs, boundary systems had no significant effect on performance SMEs, diagnostic control systems had a significant effect on performance SMEs, and interactive control systems had a significant effect on performance SMEs. The implication of this research is that it can provide a choice of a control system for the management of SMEs which has so far used conventional control systems and illustrates that the control system for the management of SMEs in local restaurants can help achieve business goals as planned.

description: This paper explores construction of gauge (diffeomorphism)-invariant observables in anti de Sitter (AdS) space and the related question of how to find a "holographic map" providing a quantum equivalence to a boundary theory. Observables are constructed perturbatively to leading order in the gravitational coupling by gravitationally dressing local field theory operators in order to solve the gravitational constraints. Many such dressings are allowed and two are explicitly examined, corresponding to a gravitational line and to a Coulomb field; these also reveal an apparent role for more general boundary conditions than considered previously. The observables obey a nonlocal algebra, and we derive explicit expressions for the boundary generators of the SO(D-1,2) AdS isometries that act on them. We examine arguments that gravity {\it explains} holography through the role of such a boundary Hamiltonian. Our leading-order gravitational construction reveals some questions regarding how these arguments work, and indeed construction of such a holographic map appears to require solution of the non-perturbative generalization of the bulk constraint equations.

description: Three-dimensional unfavourable geology models with complex structures and various attributes have become crucial for optimal design and risk control during tunnel construction. In practical applications, it is necessary to integrate multi-source advanced prediction data, including tunnel seismic prediction data, geological radar data, and transient electromagnetic data, to perform dynamic model construction. However, due to the implicit representation of the spatial distribution of single-source data and the heterogeneity of multi-source data, existing methods mainly rely on manual interpretation to perform comprehensive analysis, causing an increase in data uncertainty and unreliable, inaccurate modelling results. Therefore, this study proposes a dynamic implicit modelling method of tunnel unfavourable geology based on multi-source data fusion using a support vector machine (SVM). This method uses the SVM to fuse multi-source data and output unfavourable geological categories, including faults, fracture zones, water-rich areas, and weak rock masses, represented as spatially continuous unfavourable geological points. A globally supported radial basis function combined with a Boolean implicit calculation is used for model construction and local adaptive update. Experiments were implemented in a deep-buried tunnel, and by comparing the results with the realistic status throughout the excavation, the accuracy and adaptive ability of the proposed modelling method were well proven.

description: The non-centrosymmetric Weyl semimetal candidate, MoTe$_2$ was investigated through neutron diffraction and transport measurements at pressures up to 1.5 GPa and at temperatures down to 40 mK. Centrosymmetric and non-centrosymmetric structural phases were found to coexist in the superconducting state. Density Functional Theory (DFT) calculations reveal that the strength of the electron-phonon coupling is similar for both crystal structures. Furthermore, it was found that by controlling non-hydrostatic components of stress, it is possible to mechanically control the ground state crystal structure. This allows for the tuning of crystal symmetry in the superconducting phase from centrosymmetric to non-centrosymmetric. DFT calculations support this strain control of crystal structure. This mechanical control of crystal symmetry gives a route to tuning the band topology of MoTe$_2$ and possibly the topology of the superconducting state.

description: We study the excitation spectrum in the dimer phase of the Shastry-Sutherland model by using an unbiased variational method that works in the thermodynamic limit. The method outputs dynamical correlation functions in all possible channels. This output is exploited to identify the order parameters with the highest susceptibility (single or multitriplon condensation in a specific channel) upon approaching a quantum phase transition in the magnetic field versus the $J'/J$ phase diagram. We find four different instabilities: antiferro spin nematic, plaquette spin nematic, stripe magnetic order, and plaquette order, two of which have been reported in previous studies.

description: Designers study human behavior in order to create products and services that respond to human needs. However design also works to support the emergence of different ways of living, beyond the needs or desires uncovered with more traditional human centered design research approaches. This project takes an approach to understanding human behavior that is relatively unexplored in the field of design. Using social practices I explored new ways for designers to model human behavior. I extended the use of social practice models into the space of service design, exploring a new kind of tool and approach to help designers create services that develop and support social practices. I used Community Supported Agriculture (CSA) —a system where community members buy shares from a group of local farmers in exchange for weekly produce—as a case study for testing these new approaches.

It is often carried out by predicting possibility of landslide occurrence first from numerous landslides conditioning factors (LCFs), followed by partitioning areas with different landslide susceptibility levels. Numerous methods have been proposed for such a purpose, saying logistic regression (LR), deep learning methods, etc. Among these methods, LR is the most widely used in literature, which may be attributed to its good performance and easy-to-follow. However, few studies explore uncertainty and reliability of the LR in LSM. Furthermore, not all LCFs contribute significantly to the landslide occurrence, saying elevation, distance to roads, etc. How to objectively determine the most relevant LCFs is another issue that remains unsolved. This study proposes a Bayesian LR method for landslide susceptibility assessment (LSA), together with Markov Chain Monte Carlo (MCMC) simulation for parameter estimation. MCMC samples are used to determine the optimal model, and to quantify the uncertainty associated with the LSM. Real-life data from Shaanxi Province are used for illustration. Results show that the proposed method works reasonably well in determination of the optimal model and in uncertainty quantification in LSM.

description: We investigate the quantum measurement noise effects on the dynamics of an atomic Bose lattice gas inside an optical resonator. We describe the dynamics by means of a hybrid model consisting of a Bose--Hubbard Hamiltonian for the atoms and a Heisenberg--Langevin equation for the lossy cavity field mode. We assume that the atoms are prepared initially in the ground state of the lattice Hamiltonian and then start to interact with the cavity mode. We show that the cavity field fluctuations originating from the dissipative outcoupling of photons from the resonator lead to vastly different effects in the different possible ground state phases, i.e., the superfluid, the supersolid, the Mott- and the charge-density-wave phases. In the former two phases with the presence of a superfluid wavefunction, the quantum measurement noise appears as a driving term leading to excess noise depletion of the ground state. The time scale for the system to leave the ground scale is determined analytically. For the latter two incompressible phases, the quantum noise results in the fluctuation of the chemical potential. We derive an analytical expression for the corresponding broadening of the quasiparticle resonances.

description: Non thermal emission from galaxy clusters demonstrates the existence of relativistic particles and magnetic fields in the Intra Cluster Medium (ICM). Present instruments do not allow to firmly establish the energy associated to these components. In a few years gamma ray observations will put important constraints on the energy content of non thermal hadrons in clusters, while the combination of radio and hard X-ray data will be crucial to measure the energy content in the form of relativistic electrons and magnetic field. SIMBOL-X is expected to drive an important breakthrough in the field also because it is expected to operate in combination with the forthcoming low frequency radio telescopes (LOFAR, LWA). In this contribution we report first estimates of statistical properties of the hard X-ray emission in the framework of the re-acceleration model. This model allows to reproduce present radio data for Radio Halos and to derive expectations for future low frequency radio observations, and thus our calculations provide hints for observational strategies for future radio and hard--X-ray combined observations.

Twistor-like superstrings with D = 3, 4, 6 target-superspace and N = (1,0), (2,0), (4,0) world-sheet supersymmetry

description: We construct a manifestly $N=(4,0)$ world-sheet supersymmetric twistor-like formulation of the $D=6$ Green-Schwarz superstring, using the principle of double (target-space and world-sheet) Grassmann analyticity. The superstring action contains two Lagrange multiplier terms and a Wess-Zumino term. They are written down in the analytic subspace of the world-sheet harmonic $N=(4,0)$ superspace, the target manifold being too an analytic subspace of the harmonic $D=6\;\; N=1$ superspace. The kappa symmetry of the $D=6$ superstring is identified with a Kac-Moody extension of the world-sheet $N=(4,0)$ superconformal symmetry. It can be enlarged to include the whole world-sheet reparametrization group if one introduces the appropriate gauge Beltrami superfield into the action. To illustrate the basic features of the new $D=6$ superstring construction, we first give some details about the simpler (already known) twistor-like formulations of $D=3, N=(1,0)$ and $D=4, N=(2,0)$ superstrings.

Competitive Online Algorithms for Resource Allocation over the Positive Semidefinite Cone

description: We consider a new and general online resource allocation problem, where the goal is to maximize a function of a positive semidefinite (PSD) matrix with a scalar budget constraint. The problem data arrives online, and the algorithm needs to make an irrevocable decision at each step. Of particular interest are classic experiment design problems in the online setting, with the algorithm deciding whether to allocate budget to each experiment as new experiments become available sequentially. We analyze two greedy primal-dual algorithms and provide bounds on their competitive ratios. Our analysis relies on a smooth surrogate of the objective function that needs to satisfy a new diminishing returns (PSD-DR) property (that its gradient is order-reversing with respect to the PSD cone). Using the representation for monotone maps on the PSD cone given by Löwner's theorem, we obtain a convex parametrization of the family of functions satisfying PSD-DR. We then formulate a convex optimization problem to directly optimize our competitive ratio bound over this set. This design problem can be solved offline before the data start arriving. The online algorithm that uses the designed smoothing is tailored to the given cost function, and enjoys a competitive ratio at least as good as our optimized bound. We provide examples of computing the smooth surrogate for D-optimal and A-optimal experiment design, and demonstrate the performance of the custom-designed algorithm.

description: “Hey Neighbor! Let’s Play.” Is a masters thesis evaluating the effects games and playful interactions have in building a sense of community. Throughout the thesis, I researched the emotional connections urban residents have with their communities and neighbors, and used the research data to develop installations for play throughout pedestrian staircases in the Southside Slopes, an urban neighborhood in Pittsburgh. From these installations, I collected user feedback and evaluated how the games affected various residents of the community. From the feedback, I was able to ultimately establish several design principles to inspire and facilitate future designers interested in designing neighborhood-based games.
On the preferred length scale in the anisotropy field of extragalactic IRAS sources

description: We investigate the existence and meaning of a preferred length in the large-scale distribution of 60-micron IRAS sources applying three tests to the 2-dimensional distribution on the celestial sphere, involving respectively the rms fluctuation and the correlation function of the source number density, and the peak number statistics. For HDM models we find a best value lambda_0 = 45-55 h^{-1} Mpc for the peak of the spectral function P(k), close to the preferred wavelength lambda = 30-40 h^{-1} Mpc of naive single-scale perturbation models. A feature should indeed be generated in this range by the anticorrelation region of xi(r), although it is not detected by recent Fourier transform analyses of redshift catalogs. Our tests provide acceptable fits for CDM models with either Omega = 0.3-0.5 or Omega = 0.1-0.2, in agreement with results in current literature. However, the quality of such fits is less satisfactory than for HDM models, with the exception of the peak number statistics, and we are not able to find a parameter interval satisfying all of our tests simultaneously. These results may indicate that the cosmic spectrum is more complicated than the smooth shapes predicted by current theoretical models.
