description: We present three dimensional relativistic hydrodynamical simulations of a precessing jet interacting with the intracluster medium and compare the simulated jet structure with the observed structure of the Hydra A northern jet. For the simulations, we use jet parameters obtained in the parameter space study of the first paper in this series and probe different values for the precession period and precession angle. We find that for a precession period P = 1 Myr and a precession angle = 20 degree the model reproduces i) the curvature of the jet, ii) the correct number of bright knots within 20 kpc at approximately correct locations, and iii) the turbulent transition of the jet to a plume. The Mach number of the advancing bow shock = 1.85 is indicative of gentle cluster atmosphere heating during the early stages of the AGN's activity.

description: The understanding of organic content of protoplanetary discs is one of the main goals of the planet formation studies. As an attempt to guide the observational searches for weak lines of complex species in discs, we modelled the (sub-)millimetre spectrum of gaseous methanol (CH$_3$OH), one of the simplest organic molecules, in the representative T Tauri system. We used 1+1D disc physical model coupled to the gas-grain ALCHEMIC chemical model with and without 2D-turbulent mixing. The computed CH$_3$OH abundances along with the CH$_3$OH scheme of energy levels of ground and excited torsional states were used to produce model spectra obtained with the non-local thermodynamic equilibrium (non-LTE) 3D line radiative transfer code LIME. We found that the modelled non-LTE intensities of the CH$_3$OH lines can be lower by factor of $>10$--$100$ than those calculated under assumption of LTE. Though population inversion occurs in the model calculations for many (sub-)millimetre transitions, it does not lead to the strong maser amplification and noticeably high line intensities. We identify the strongest CH$_3$OH (sub-)millimetre lines that could be searched for with the Atacama Large Millimeter Array (ALMA) in nearby discs. The two best candidates are the CH$_{3}$OH $5_0-4_0~A^+$ (241.791 GHz) and $5_{-1}-4_{-1}~E$ (241.767 GHz) lines, which could possibly be detected with the $\sim5σ$ signal-to-noise ratio after $\sim3$ hours of integration with the full ALMA array.

New business models to support sustainable development: The case of energy-efficiency measures in buildings

Publisher: name: Karlsruhe
Year: 2019

description: The German government has set ambitious climate-protection targets to limit global warming. The aim is to achieve an energy-efficient and almost climate-neutral building stock by 2050. This applies particularly to buildings, responsible for more than 20% of CO2 emissions. The aim is to reduce the primary energy demand of buildings by 80% by the end of 2050. Achieving a nearly climate-neutral building stock requires targeted modernization measures that contribute to increasing energy efficiency. Barriers confronting the implementation of energy-efficient measures include lack of knowledge due to inadequate provision of information, lack of trust, and problems regarding financing possibilities. Therefore, solutions are needed for holistic concepts that make energy-efficient building and modernization more attractive. In addition to traditional business models (BM), measures that accelerate the implementation of energy-efficiency and BM that support the sustainable development of potential customers are sought. Expert knowledge must be shared to close information gaps; savings guarantees must be considered to build trust, and finally, financing possibilities must be available to support implementing sustainable measures. The research focuses on a modification of BM under the aspect of increasing energy efficiency in buildings for customers. This approach considers specific functions, effects, and benefits of BM. The aim of this extension is to create a basis for systematizing existing BM on the one hand, and on the other, to extend the proposed methodology. Finally, the developed guide supports startups designing new BM.

description: Throughout the current global health crisis, false and misleading content has proliferated on social media. Previous research indicates that users of social media primarily share information that contains attention-grabbing elements. Because sensationalist elements are prevalent in disinformation, this study examines the role of sensationalism in supporting disinformation. We conducted survey experiments in six countries (N = 7,009), presenting versions of a false claim that differed in their degree of sensationalism. We varied three contextual conditions for disinformation support: whether respondents grew up in a tabloid-oriented national news culture, whether they indicated individual usage preferences for tabloid and alternative media, and how they rated their situational uncertainty during the pandemic. Our results show a weak influence of tabloidized cultures, but people who frequently use tabloid or alternative media are more likely to agree with disinformation. Users who are uncertain about what is true and what is false are also more likely to agree with disinformation, especially when it is presented sensationally. The average user, however, is more likely to agree with disinformation that is presented neutrally. This finding is concerning, as disinformation presented in a sober manner is much harder to detect by those who want to fight the “infodemic.”

description: PV systems using bifacial solar modules have shown an increased energy harvest compared to systems
with standard, monofacial panels. Due to bifaciality of the modules, the tilt angle, the installation height, the distance
between the modules and in particular the ground reflectance have a significant influence on the energy harvest. For
bifacial module arrays reflective elements in between the rows might be an option in order to achieve a low light
concentration resulting in a further increased energy harvest. A simulation of such conditions is hardly possible;
measurements at real systems would require considerable effort. In this work we present results obtained by a
measuring setup with rotating mini modules. In particular the influence of the ground reflection was studied by using
various grounds and reflecting elements with different shapes. Prior to the analysis of the reflector elements the
measurement setup is described and the assignability of results from the miniaturized test array to a corresponding
large scale system is demonstrated.

description: Quantum signal processing (QSP) is a powerful toolbox for the design of quantum algorithms and can lead to asymptotically optimal computational costs. Its realization on noisy quantum computers without fault tolerance, however, is challenging because it requires a deep quantum circuit in general. We propose a strategy to run an entire QSP protocol on noisy quantum hardware by carefully reducing overhead costs at each step. To illustrate the approach, we consider the application of Hamiltonian simulation for which QSP implements a polynomial approximation of the time evolution operator. We test the protocol by running the algorithm on the Quantinuum H1-1 trapped-ion quantum computer powered by Honeywell. In particular, we compute the time dependence of bipartite entanglement entropies for Ising spin chains and find good agreements with exact numerical simulations. To make the best use of the device, we determine optimal experimental parameters by using a simplified error model for the hardware and numerically studying the trade-off between Hamiltonian simulation time, polynomial degree, and total accuracy. Our results are the first step in the experimental realization of QSP-based quantum algorithms.

description: With the increasing efficiency demands of photovoltaic (PV) industry, a number of new design and
high efficiency silicon solar cells were appeared. Photovoltaic module performance measurement has become more
important. The traditional simulator with standard spectrum and short pulse cannot test modules performance
accurately, especially in high efficiency solar modules. In this work we studied the current–voltage (I–V)
performance comparison of different type crystalline silicon modules with four laboratories. In this paper intercomparison
results of short-circuit current (Isc), open circuit voltage (Voc), maximum output power (Pmax), and
fill factor (F.F.) are discussed. Finally, we found the optimum solution of transient effect on the high efficiency HIT
(Heterojunction with Intrinsic Thin layer) and bifacial solar modules. The solar simulator used 120msec long pulse
can improve these defects for high-efficiency solar modules measurement.

description: Adaptive filtering belongs to the realm of learning algorithms, widely used in our daily life in the context of machine learning, artificial intelligence, pattern recognition, etc. It is formally defined as a self-designing device with time-varying parameters that are adjusted recursively in accordance with the input data. The trigger mechanism is a central task in experiments using antennas to detect cosmic rays as it selects a cosmic- ray induced signal among all the voltages traces events that reach the antennas. This work presents the efficiency of a trigger mechanism developed using the adaptive predictor filter technique, whose capability is well known for time series prediction usage. This technique is independent of an external detector, using only the online temporal field recorded by the antennas in a simulated data set and Gaussian noise.

description: We show that the chiral modes in circular graphene $pn$ junctions provide an advantage for spin manipulation via spin-orbit coupling compared to semiconductor platforms. We derive the effective Hamiltonian for the spin dynamics of the junction's zero modes and calculate their quantum phases. We find a sweet spot in parameter space where the spin is fully in-plane and radially polarized for a given junction polarity. This represents a shortcut to singular spin configurations that would otherwise require spin-orbit coupling strengths beyond experimental reach.

description: Modules with bifacial technology show a high gain compared to monofacial modules, due to utilization
of an illuminated rear side, as reported in different publications [1, 2]. The utilization of both sides leads to new
opportunities for outside applications, such as open field or building integrated (BIPV) installations. Regarding this
fact, bifacial module design optimization is challenging. This paper investigates the outdoor bifacial behavior for
different angles of incidence (AOI) with the help of an individual-driven two-axis tracking system. With a bifacial
module, the angular dependent response under outdoor conditions gets a new significance due to the additional
contribution of the rear incident light. In this paper, the performances of bifacial and monofacial modules are
compared to each other considering installation scenario, AOI, direct and diffuse irradiance, module temperature and
backlight conditions. The paper shows the module preparation, measuring set-up and tracking sequences as well as an
improved method to evaluate the relative gain.

description: The $Z^\pm_c(3900)/Z^\pm_c(3885)$ resonant structure has been experimentally observed in the $Y(4260) \to J/ψππ$ and $Y(4260) \to \bar{D}^\ast D π$ decays. This structure is intriguing since it is a prominent candidate of an exotic hadron. Yet, its nature is unclear so far. In this work, we simultaneously describe the $\bar{D}^\ast D$ and $J/ψπ$ invariant mass distributions in which the $Z_c$ peak is seen using amplitudes with exact unitarity. Two different scenarios are statistically acceptable, where the origin of the $Z_c$ state is different. They correspond to using energy dependent or independent $\bar D^* D$ $S$-wave interaction. In the first one, the $Z_c$ peak is due to a resonance with a mass around the $D\bar D^*$ threshold. In the second one, the $Z_c$ peak is produced by a virtual state which must have a hadronic molecular nature. In both cases the two observations, $Z^\pm_c(3900)$ and $Z^\pm_c(3885)$, are shown to have the same common origin, and a $\bar D^* D$ bound state solution is not allowed. Precise measurements of the line shapes around the $D\bar D^*$ threshold are called for in order to understand the nature of this state.

description: It is crucial in clinical trials to investigate treatment effect consistency across subgroups defined by patient baseline characteristics. However, there may be treatment effect variability across subgroups due to small subgroup sample size. Various Bayesian models have been proposed to incorporate this variability when borrowing information across subgroups. These models rely on the underlying assumption that patients with similar characteristics will have similar outcomes to the same treatment. Patient populations within each subgroup must subjectively be deemed similar enough Pocock (1976) to borrow response information across subgroups. We propose utilizing the machine learning method of Bayesian Additive Regression Trees (BART) to provide a method for subgroup borrowing that does not rely on an underlying assumption of homogeneity between subgroups. BART is a data-driven approach that utilizes patient-level observations. The amount of borrowing between subgroups automatically adjusts as BART learns the covariate–response relationships. Modeling patient-level data rather than treating the subgroup as a single unit minimizes assumptions regarding homogeneity across subgroups. We illustrate the use of BART in this context by comparing performance from existing subgroup borrowing methods in a simulation study and a case study in non-small cell lung cancer. The application of BART in the context of subgroup analyses alleviates the need to subjectively choose how much information to borrow based on subgroup similarity. Having the amount of borrowing be analytically determined and controlled for based on the similarity of individual patient-level characteristics allows for more objective decision making in the drug development process with many other applications including basket trials.

description: PV energy is the direct conversion of solar radiation into electricity. In this paper, an analysis of the
influence of parameters such as global irradiance or temperature in the performance of a PV installation has been
carried out.
A PV module was installed in a building at the University of Málaga, and these parameters were experimentally
determined for different days and different conditions of irradiance and temperature. Moreover, IV curves were
obtained under these conditions to know the open-circuit voltage and the short-circuit current of the module. With
this information, and using the first law of thermodynamics, an energy analysis was performed to determine the
energy efficiency of the installation. Similarly, using the second law of thermodynamics, an exergy analysis is used to
obtain the exergy efficiency.
The results show that the energy efficiency varies between 10% and 12% and the exergy efficiency between
14% and 17%. It was concluded that the exergy analysis is more suitable for studying the performance, and that only
electric exergy must be considered as useful exergy. This exergy efficiency can be improved if heat is removed from
the PV module surface, and an optimal temperature is reached.

description: This paper compares the performances of three standalone inverters used in SPV applications, having three output configurations, viz. transformer less (TL), EI core and toroid core (TC) transformers. The performance is analyzed in terms of efficiency, harmonics generation, crest factor (CF), power factor (PF) and weighted factor for efficiency for linear (LN) and non-linear (NL) type of loads. It is observed that for linear loads the weighted factor of efficiency more than 87%, for TL, EI and TC are 0.85, 0.75 & 0.55 correspondingly whereas for Nonlinear load weighted factor for efficiency more than 85% are 0.80, 0.75 and 0.35 respectively. It has been also observed that in TL inverter distortion in voltage (Uthd) and variation in crest factor (CF) is comparatively less than rest of two other configurations. Further the study also gives the approach for selection of suitable topology of inverter based upon loads requirement.

description: We develop a linear-response transport theory of diffusive spin and heat transport by magnons in magnetic insulators with metallic contacts. The magnons are described by a position dependent temperature and chemical potential that are governed by diffusion equations with characteristic relaxation lengths. Proceeding from a linearized Boltzmann equation, we derive expressions for length scales and transport coefficients. For yttrium iron garnet (YIG) at room temperature we find that long-range transport is dominated by the magnon chemical potential. We compare the model's results with recent experiments on YIG with Pt contacts [L.J. Cornelissen, et al., Nat. Phys. 11, 1022 (2015)] and extract a magnon spin conductivity of $σ_{m}=5\times10^{5}$ S/m. Our results for the spin Seebeck coefficient in YIG agree with published experiments. We conclude that the magnon chemical potential is an essential ingredient for energy and spin transport in magnetic insulators.

description: In building integrated photovoltaic (PV) systems, the reflection of the solar radiation by the walls of
the buildings may cause a non-uniform distribution of the incident radiation on the different PV modules. However,
by using micro-inverters at strings levels, electricity production may increase instead of provoking losses by
mismatching. For this purpose, the maximum possible solar gain due to reflections is required.
The annual profit of the solar radiation depends on factors such as climate, latitude and the relative position of the cell
to the reflective surface. In the location of Seville (Spain), the gain on a PV cell generation due to radiation reflected
by a TiO2 treated perpendicular surface reaches a 13% for an entire year. Therefore, it is well demonstrated that using
micro-inverters not only involves a loss reduction of a solar installation but also to obtain a profit from the solar
radiation that cannot be achieved with centralized inverters.

description: Natural odors typically consist of many molecules at different concentrations. It is unclear how the numerous odorant molecules and their possible mixtures are discriminated by relatively few olfactory receptors. Using an information-theoretic model, we show that a receptor array is optimal for this task if it achieves two possibly conflicting goals: (i) each receptor should respond to half of all odors and (ii) the response of different receptors should be uncorrelated when averaged over odors presented with natural statistics. We use these design principles to predict statistics of the affinities between receptors and odorant molecules for a broad class of odor statistics. We also show that optimal receptor arrays can be tuned to either resolve concentrations well or distinguish mixtures reliably. Finally, we use our results to predict properties of experimentally measured receptor arrays. Our work can thus be used to better understand natural olfaction and it also suggests ways to improve artificial sensor arrays.

description: A steady state solar simulator has been set up at the ZAE Bayern. The system is meant to be used for
the characterization of photovoltaic (PV) of various technologies. In particular, it can be used for pre-conditioning of
thin film modules in order to enable reliable power and I-V measurements. Furthermore, it allows for determining the
temperature coefficient of PV modules of various technologies. The latter application will also be discussed in this
work. Here, the optimization of the steady state solar simulator based on a method originally introduced by
Hishikawa et al. for pulsed solar simulators is described and the results of this optimization are presented.
An h-multigrid approach for high-order discountinuous Galerkin methods
Creators: name: TESINI, Pietro Francesco Mar
Publisher: name: Universit� degli studi di Bergamo
Year: 2008

description: The thesis presents the development of an h-multigrid solver for high-order accurate discontinuous Galerkin (DG) discretizations of non-linear systems of conservations laws on unstructured grids. For this purpose, a high-order DG discretization on polyhedral grids is developed first and it is applied to the compressible Navier-Stokes equations. The proposed method employs shape functions, consisting of complete polynomials defined in the real space, which are hierarchic and orthonormal on arbitrarily shaped elements. As regards the discretization of the viscous terms of the Navier-Stokes equations, we use the well-known method introduced in [6] with suitably enlarged values of the stability parameter reported in [1]. The accuracy and the convergence properties of the method have been tested against classical inviscid problems such as the transonic Ringleb flow and the subsonic flow over a Gaussian bump. The Helmholtz problem and the solution of the Navier-Stokes equations around a NACA0012 airfoil have been used as viscous tests. Then we present the development of an h-multigrid method where coarse grid levels are constructed by agglomerating neighbouring elements of the fine grid. First, an elegant yet practical set of transfer operators is derived for general space settings and for the current one. After that, a quasi-implicit multistage h-multigrid iteration strategy for the discontinuous Galerkin discretization of the steady Euler equations is developed and numerically investigated. Results are presented for a subsonic flow over a NACA0012 airfoil at 2o of incidence. These results highlight the main properties of the developed multigrid scheme and its different behaviour with respect to the classic p-multigrid scheme.

PV Cells and Modules

description: To minimize the measurement uncertainty of indoor measurements of PV module efficiency, the
accurate determination of the spatial distribution of irradiation is essential. The international standard IEC 60904-9
(2007) describes procedures to classify the basic optical properties of solar simulators, including the measurement of
the spatial distribution of irradiation [1]. The development and characterization of high quality light sources for solar
simulation with lowest non-uniformity requires adequate means and methods to determine repeatable and reliable
values of the irradiance non-uniformity.
We present different methods for measuring pulsed solar simulators irradiance uniformity on PV module scale and
discuss the results obtained with the different methods. Herein, special emphasis is laid on the characterization and
evaluation of the measurement equipment used and the impact on measurement uncertainty for the irradiance
non-uniformity. According to our observations, it is required to consider local temporal stability of the irradiance
distribution for precise and comparable measurements. In our investigation, we are also involving optical properties
of typical crystalline silicon c-Si device under test modules to be part of the uncertainty analysis of non-uniformity
measurements.
We discuss the requirements for equipment and methods to report reliable values on solar simulators irradiance nonuniformity
below 1 % and the corresponding measurement uncertainty affecting PV module efficiency
measurements.

description: The Fukuda-stepping-test (FST), i.e., repetitive walking on the spot while blindfolded, has been proposed as a means to assess the integrity of the vestibular pathways. While its sensitivity to detect abnormalities in patients is limited, it may be useful in studying the physiology of the subjective-straight-ahead (SSA). Considering reported systematic shifts in SSA in humans, we hypothesize that such asymmetries arise from individual differences in the orientation/configuration of the macular organs and in central processing of vestibular input. We hypothesize that such asymmetries are stable over time in individual subjects. Alternatively, such asymmetries may arise from random noise in the sensory/motor systems involved, demonstrating low reproducibility over time. Materials and methods: Twenty-four subjects walked on the spot over 60 s while blindfolded. Using an inertial measurement unit (IMU) placed at the chest, angular deviations were recorded and compared to manually-measured final positions. Both static (direction, magnitude) and dynamic (time-to-onset of deviation, pattern of deviations) parameters were retrieved from the yaw slopes. Significant deviations were found in 15/24 participants for the manual measurements (leftwards = 8; rightwards = 7), whereas when using the IMU-sensor 13/24 participants showed significant shifts (leftwards = 9; rightwards = 4). There was a high correlation (0.98) between manually measured rotation angles (average absolute deviations = 58.0 deg ± 48.6 deg; intra-individual variability = 39 deg ± 24 deg) and sensor-based yaw slopes (1.00 deg/s ± 0.88 deg/s; 0.67 deg/s ± 0.41 deg/s). Relevant yaw deviation was detected 22.1 s ± 12.3 s (range = 5.6 s-59.2 s) after the onset of marching (no relevant yaw-deviation in 15/139 measurements), showing a mostly linear behavior over time. Conclusion: We observed significant inter-individual variability in task performance in the FST, reproducing findings from previous studies. With test-re-test reliability being moderate only, but at the same time observing a preference in the side of shifts in most trials and subjects, we conclude that likely both individually varying estimates of straight-ahead and random noise contribute to the pattern of angular deviations observed. Using an IMU-sensory based approach, additional dynamic parameters could be retrieved, emphasizing the value of such a quantitative approach over manual measurements. Such an approach may provide useful additional information to distinguish patients from healthy controls.

description: The performance of commercial PV modules has been compared under field conditions at HHI’s outdoor testbed, located in South Korea. We have established the testbed with the capability of PV monitoring system in which can be collected the individual PV modules’ electrical data and meteorological data including solar irradiation, ambient temperature, humidity, wind speed etc. This study was characterized outdoor module performance of several commercial modules, which were purchased from market. In this experiment, it is found that the light-induced degradation (LID) and the cell structure are the significant factors to determine the performance ratio (PR) of the modules under same field conditions. The performance ratio of LID-resistant mono-PERC module has the highest value due to the lower LID and the better cell structure. Additionally, it is investigated that multi-wire busbar can improve the PR of module by reducing the electrical loss of the module.

description: We consider a congested aggregation model that describes the evolution of a density through the competing effects of nonlocal Newtonian attraction and a hard height constraint. This provides a counterpoint to existing literature on repulsive-attractive nonlocal interaction models, where the repulsive effects instead arise from an interaction kernel or the addition of diffusion. We formulate our model as the Wasserstein gradient flow of an interaction energy, with a penalization to enforce the constraint on the height of the density. From this perspective, the problem can be seen as a singular limit of the Keller-Segel equation with degenerate diffusion. Two key properties distinguish our problem from previous work on height constrained equations: nonconvexity of the interaction kernel (which places the model outside the scope of classical gradient flow theory) and nonlocal dependence of the velocity field on the density (which causes the problem to lack a comparison principle). To overcome these obstacles, we combine recent results on gradient flows of nonconvex energies with viscosity solution theory. We characterize the dynamics of patch solutions in terms of a Hele-Shaw type free boundary problem and, using this characterization, show that in two dimensions patch solutions converge to a characteristic function of a disk in the long-time limit, with explicit rate of convergence. We believe that a key contribution of the present work is our blended approach, combining energy methods with viscosity solution theory.

description: Indian climate is broadly divided into 4 climatic zones, Hot & dry, Hot & humid, Composite and cold & Cloudy. Most of the area comes under composite climate [1]. Further the performance of SPV power plants depends on the site, PV Module technology and load wise inverters/power converters efficiency. So with the change of the technology and site, weighted efficiency of the inverter also varies. This paper coins the new efficiency term as Indian© efficiency based on irradiation distribution similar as European and Californian efficiency which is suitable to Indian climatic condition. To showing technology and site dependency the study also compares the Indian© weighted efficiency of a sample inverter with weighted efficiency using the generation energy weighted factors of a-si, multi-si, HIT and CdTe technology module. It is found that same inverter performs best with CdTe Modules in the composite climate zone of India.

description: Throughout the current global health crisis, false and misleading content has proliferated on social media. Previous research indicates that users of social media primarily share information that contains attention-grabbing elements. Because sensationalist elements are prevalent in disinformation, this study examines the role of sensationalism in supporting disinformation. We conducted survey experiments in six countries (N = 7,009), presenting versions of a false claim that differed in their degree of sensationalism. We varied three contextual conditions for disinformation support: whether respondents grew up in a tabloid-oriented national news culture, whether they indicated individual usage preferences for tabloid and alternative media, and how they rated their situational uncertainty during the pandemic. Our results show a weak influence of tabloidized cultures, but people who frequently use tabloid or alternative media are more likely to agree with disinformation. Users who are uncertain about what is true and what is false are also more likely to agree with disinformation, especially when it is presented sensationally. The average user, however, is more likely to agree with disinformation that is presented neutrally. This finding is concerning, as disinformation presented in a sober manner is much harder to detect by those who want to fight the “infodemic.”

description: In this contribution, we propose a kernel-based method for the identification of linear systems from noisy and incomplete input-output datasets. We model the impulse response of the system as a Gaussian process whose covariance matrix is given by the recently introduced stable spline kernel. We adopt an empirical Bayes approach to estimate the posterior distribution of the impulse response given the data. The noiseless and missing data samples, together with the kernel hyperparameters, are estimated maximizing the joint marginal likelihood of the input and output measurements. To compute the marginal-likelihood maximizer, we build a solution scheme based on the Expectation-Maximization method. Simulations on a benchmark dataset show the effectiveness of the method.

description: A Kakeya set in the linear representation $T^{*}_{2}(\mathcal{C})$, $\mathcal{C}$ a non-singular conic, is the point set covered by a set of $q+1$ lines, one through each point of $\mathcal{C}$. In this article we classify the small Kakeya sets in $T^{*}_{2}(\mathcal{C})$. The smallest Kakeya sets have size $\left\lfloor\frac{3q^{2}+2q}{4}\right\rfloor$, and all Kakeya sets with weight less than $\left\lfloor\frac{3(q^{2}-1)}{4}\right\rfloor+q$ are classified: there are approximately $\sqrt{\frac{q}{2}}$ types.
