description: This work describes the development of a simulation tool which allows the simulation of the Internal Combustion Engine (ICE), the transmission and the vehicle dynamics. It is a control oriented simulation tool, designed in order to perform both off-line (Software In the Loop) and on-line (Hardware In the Loop) simulation. In the first case the simulation tool can be used in order to optimize Engine Control Unit strategies (as far as regard, for example, the fuel consumption or the performance of the engine), while in the second case it can be used in order to test the control system. 

In recent years the use of HIL simulations has proved to be very useful in developing and testing of control systems. Hardware In the Loop simulation is a technology where the actual vehicles, engines or other components are replaced by a real time simulation, based on a mathematical model and running in a real time processor. The processor reads ECU (Engine Control Unit) output signals which would normally feed the actuators and, by using mathematical models, provides the signals which would be produced by the actual sensors.

The simulation tool, fully designed within Simulink, includes the possibility to simulate the only engine, the transmission and vehicle dynamics and the engine along with the vehicle and transmission dynamics, allowing in this case to evaluate the performance and the operating conditions of the Internal Combustion Engine, once it is installed on a given vehicle. Furthermore the simulation tool includes different level of complexity, since it is possible to use, for example, either a zero-dimensional or a one-dimensional model of the intake system (in this case only for off-line application, because of the higher computational effort).

Given these preliminary remarks, an important goal of this work is the development of a simulation environment that can be easily adapted to different engine types (single- or multi-cylinder, four-stroke or two-stroke, diesel or gasoline) and transmission architecture without reprogramming. Also, the same simulation tool can be rapidly configured both for off-line and real-time application. The Matlab-Simulink environment has been adopted to achieve such objectives, since its graphical programming interface allows building flexible and reconfigurable models, and real-time simulation is possible with standard, off-the-shelf software and hardware platforms (such as dSPACE systems).

description: For human beings, the processing of text streams of unknown size leads generally to problems because e.g. noise must be selected out, information be tested for its relevance or redundancy, and linguistic phenomenon like ambiguity or the resolution of pronouns be advanced. Putting this into simulation by using an artificial mind-map is a challenge, which offers the gate for a wide field of applications like automatic text summarization or punctual retrieval. In this work we present a framework that is a first step towards an automatic intellect. It aims at assembling a mind-map based on incoming text streams and on a subject-verb-object strategy, having the verb as an interconnection between the adjacent nouns. The mind-map's performance is enriched by a pronoun resolution engine that bases on the work of D. Klein, and C. D. Manning.

description: In this paper we investigate the nature of the transition from Abelian to non-Abelian confinement (i.e. crossover vs. phase transition). To this end we consider the basic N=2 model where non-Abelian flux tubes (strings) were first found: supersymmetric QCD with the U(N) gauge group and N_f=N flavors of fundamental matter (quarks). The Fayet-Iliopoulos term ξtriggers the squark condensation and leads to the formation of non-Abelian strings. There are two adjustable parameters in this model: ξand the quark mass difference Δm. We obtain the phase diagram on the (ξ, Δm) plane. At large ξand small Δm the world-sheet dynamics of the string orientational moduli is described by N=2 two-dimensional CP(N-1) model. We show that as we reduce ξthe theory exhibits a crossover to the Abelian (Seiberg-Witten) regime. Instead of N^2 degrees of freedom of non-Abelian theory now only N degrees of freedom survive in the low-energy spectrum. Dyons with certain quantum numbers condense leading to the formation of the Abelian Z_N strings whose fluxes are fixed inside the Cartan subalgebra of the gauge group. As we increase N this crossover becomes exceedingly sharper becoming a genuine phase transition at N =\infty.

description: We have used neutron scattering techniques to characterize the diffuse scattering and lattice dynamics in single crystals of the relaxor PMN from 10K to 900K. We observed two distinct types of diffuse scattering. The first is weak, relatively temperature independent, persists to at least 900 K, and forms bow-tie-shaped patterns in reciprocal space centered on (h00) Bragg peaks. We associate this primarily with chemical short-range order. The second is strong, temperature dependent, and forms butterfly-shaped patterns centered on (h00) Bragg peaks. This diffuse scattering has been attributed to the PNR because it responds to an electric field and vanishes near Td ~ 620K when measured with thermal neutrons. Surprisingly, it vanishes at 420K when measured with cold neutrons, which provide ~4 times superior energy resolution. That this onset temperature depends on the instrumental energy resolution demands a reassessment of the Burns temperature Td. Neutron backscattering measurements made with 300 times better energy resolution confirm the onset temperature of 420+/-20K. The energy width of the diffuse scattering is resolution limited, indicating that the PNR are static on timescales of at least 2 nsec. Transverse acoustic (TA) phonon lifetimes are temperature independent up to 900K for q < 0.2 1/A. This motivates a physical picture in which sufficiently long-wavelength TA phonons average over the PNR; only those TA phonons having wavelengths comparable to the size of the PNR are affected. The PMN lattice constant changes by less than 0.001 Angstroms below 300K, but expands rapidly at a rate of 2.5x10^-5 1/K at high temperature. The regimes of low and high thermal expansion bracket the revised value of Td, which suggests the anomalous thermal expansion results from the condensation of static PNR.

Waste management, reduction, reuse and recycling

description: Waste management is crucial in addressing environmental pollution and public health concerns. A study used chemical looping combustion (CLC) to process waste sludge from the Ankara Central Wastewater Treatment Plant and red mud from Eti Aluminum as an oxygen carrier. Analytical methods showed the red mud's suitability as an oxygen carrier, resulting in zero emissions. Waste sludge was found to have an energy value similar to brown coal, and the ash produced could be used in cement and fertilizer production. This novel technology provides a zero-waste and zero-carbon footprint approach to waste management, helping to reduce environmental impacts.

description: A recent survey of the Local Group spiral galaxy M 31 with XMM-Newton yielded a large number of X-ray sources. This is the second in a series of papers with the aim of identifying the optical counterparts of these X-ray sources. We have obtained optical spectra for 21 bright optical counterparts of 20 X-ray sources in the direction of M 31, using the 1.3-m Skinakas telescope in Crete, Greece. For 17 of the 20 X-ray sources, we have identified the optical counterpart as a normal late type star (of type F or later) in the foreground (i.e. in the Milky Way). For two more sources there were two possible optical counterparts in each case, while two more objects have X-ray properties that are not compatible with the spectral characteristics of late type non-flaring stars.

The origin of the high Q air-slot cavity mode is the mode-gap effect from the slotted photonic crystal waveguide mode with negative dispersion. The high Q cavities with ultrasmall mode volume are important for applications such as cavity quantum electrodynamics, nonlinear optics and optical sensing.

Subjects: M-PSI/08 Psicologia clinica

description: The present work explores the psychosocial issues emerging from a large cross-sectional study aimed to assess the prevalence, clinical manifestations, and psychosocial correlates of hyperandrogenism in a population of Italian high school students. 
Participants were 1804 adolescents, aged between 15 and 19 years, who volunteered to fill in a package of self-report questionnaires (including the Psychosocial Index, the Symptom Questionnaire and Ryff’s Psychological Well-Being scales for the assessment of psychological aspects) and undergo a comprehensive physical examination. 
Significant gender differences were found with regard to psychological distress, with females reporting higher scores compared with males, but not on well-being dimensions. The relationships of well-being to distress were found to be complex. Although inversely associated, well-being and ill-being appeared to be distinct domains of mental functioning. The evaluation of the moderating effects of well-being in the association between stress and psychological distress indicated that well-being may act as a protective factor, contributing to less pronounced psychological distress as stress levels increased. 
Higher rates of somatic complaints were found among current smokers. However, substance use (i.e., smoking and drug use) was also found to be positively associated with some well-being dimensions. A considerable number of participants were found to present with disordered eating symptoms, particularly females, and associated higher stress levels and lower quality of life. Sport activities were found to favourably affect psychological health.
As to clinical signs of hyperandrogenism, a significant impairment in psychosocial functioning was found among females, whereas no effects on psychological measures could be detected among males. Subgroups of adolescents with distinct clinical and psychological characteristics could be identified by means of cluster analysis. 
The present study provides new insights into better understanding of the complex relationships between well-being, distress and health status in the adolescent population, with important clinical implications.
A programmable oceanographic winch controller

Publisher: name: University of British Columbia
Year: 2010

description: A position servo controller for an oceanographic winch is designed, implemented and tested. Depth, speed and acceleration of a payload are made programmable. Cable position and speed feedbacks are implemented to control the depth of the payload. Provision is made to compensate for the wave-induced motions of the ship deck. For this purpose, the instantaneous vertical deck position is determined using three orthogonal accelerometers fixed to the deck. Tests of the position servo system are successful, but limited by constraints of the hydraulic system used. Compensation for rapid deck motions is possible; however, compensation for slow deck motions causes noticeable drifts in the payload depth due to integrating small errors in the acceleration signal.

description: Hidden Markov models are traditionally decoded by the Viterbi algorithm which finds the highest probability state path in the model. In recent years, several limitations of the Viterbi decoding have been demonstrated, and new algorithms have been developed to address them \citep{Kall2005,Brejova2007,Gross2007,Brown2010}. In this paper, we propose a new efficient highest expected reward decoding algorithm (HERD) that allows for uncertainty in boundaries of individual sequence features. We demonstrate usefulness of our approach on jumping HMMs for recombination detection in viral genomes.

Year: 2008
Subjects: ING-IND/15 Disegno e metodi dell'ingegneria industriale

description: This artwork reports on two different projects that were carried out during the three years of Doctor of the Philosophy course.
In the first years a project regarding Capacitive Pressure Sensors Array for Aerodynamic Applications was developed in the Applied Aerodynamic research team of the Second Faculty of Engineering, University of Bologna, Forlì, Italy, and in collaboration with the ARCES laboratories of the same university. Capacitive pressure sensors were designed and fabricated, investigating theoretically and experimentally the sensor’s mechanical and electrical behaviours by means of finite elements method simulations and by means of wind tunnel tests. During the design phase, the sensor figures of merit are considered and evaluated for specific aerodynamic applications. The aim of this work is the production of low cost MEMS-alternative devices suitable for a sensor network to be implemented in air data system.
The last two year was dedicated to a project regarding Wireless Pressure Sensor Network for Nautical Applications. Aim of the developed sensor network is to sense the weak pressure field acting on the sail plan of a full batten sail by means of instrumented battens, providing a real time differential pressure map over the entire sail surface. The wireless sensor network and the sensing unit were designed, fabricated and tested in the faculty laboratories. A static non-linear coupled mechanical-electrostatic simulation, has been developed to predict the pressure versus capacitance static characteristic suitable for the transduction process and to tune the geometry of the transducer to reach the required resolution, sensitivity and time response in the appropriate full scale pressure input A time dependent viscoelastic error model has been inferred and developed by means of experimental data in order to model, predict and reduce the inaccuracy bound due to the viscolelastic phenomena affecting the Mylar® polyester film used for the sensor diaphragm. The development of the two above mentioned subjects are strictly related but presently separately in this artwork.
Coherent lensless matched filter and an application to feature extraction in character recognition
Creators: name: Bage, Marc J.
Publisher: name: University of British Columbia
Year: 2010

description: Reduction of space variance in coherent matched filtering is considered in the context of parallel character recognition. The space variance due to vignetting apertures is eliminated by synthesizing the effect of the second lens of the Vander Lugt matched filter (MT) inside the hologram. This leads to two types of lensless matched filter (LLMF) depending on the curvature of the reference beam and the relative scale of the recorded and readout signals. For a given space-bandwidth product, two layouts of recorded and readout signals are found to minimize the space variance due to the volume of the recording medium. They are well suited for line-by-line character recognition. A study of the holographic aberrations indicates for which of these layouts the space variance of the root mean square (rms) distortion is smallest. Computer-generated plots are used to investigate the space variance of the rms astigmatism of the MF and LLMF. The condition that makes the spherical aberration and coma null is also derived. Various aspects of the LLMF are examined. The LLMF acts simultaneously as a MF and a Fresnel zone plate. Therefore, when the hologram is displaced, the LLMF behavior results from the combined displacements of its filter component and lens component. In the output plane, the correlation component only is focused by the lens component. The other diffracted output components are unfocused images. They contribute noise that affects the correlation signal. In practical cases of parallel processing, the signal-to-noise ratios of the MF and LLMF at the same reference beam angle are comparable and the resolution of available recording media places no restriction on the field of view or the signals bandwidth. Improvement of the recognition performance is another concern of the thesis. It is shown experimentally that a filter matched to character features (FEMF) discriminates better between the similar looking characters O and Q than a high-pass filter matched to their high frequency components (HPMF). Yet its sensitivity to variants is not as severe as that of the EPMF when the feature extractor is a low-pass filter. Also this low-pass filtering reduces the aberrations and allows for a detector with a coarser resolution. The increased reliability of the FEMF is achieved at the expense of a reduced diffraction efficiency and of a more critical registration of the readout signal. Experimental considerations emphasize the importance of phase accuracy in the input plane. Finally, suggestions for further research are presented.
Temperature, magnetic field, and pressure dependence of the crystal and magnetic structures of the magnetocaloric compound Mn1.1Fe0.9(P0.8Ge0.2)

description: Neutron powder diffraction studies of the crystal and magnetic structures of the magnetocaloric compound Mn1.1Fe0.9(P0.8Ge0.2) have been carried out as a function of temperature, applied magnetic field, and pressure. The data reveal that there is only one transition observed over the entire range of variables explored, which is a combined magnetic and structural transformation between the paramagnetic to ferromagnetic phases (Tc~255 K for this composition). The structural part of the transition is associated with an expansion of the hexagonal unit cell in the direction of the a- and b-axes and a contraction of the c-axis as the FM phase is formed, which originates from an increase in the intra-layer metal-metal bond distance. The application of pressure is found to have an adverse effect on the formation of the FM phase since pressure opposes the expansion of the lattice and hence decreases Tc. The application of a magnetic field, on the other hand, has the expected effect of enhancing the FM phase and increasing Tc. We find that the substantial range of temperature/field/pressure coexistence of the PM and FM phases observed is due to compositional variations in the sample. In-situ high temperature diffraction measurements were carried out to explore this issue, and reveal a coexisting liquid phase at high temperatures that is the origin of this variation. We show that this range of coexisting phases can be substantially reduced by appropriate heat treatment to improve the sample homogeneity.

description: Experiments at the Large Hadron Collider (LHC) might test the picture of supersymmetric Grand Unification in particle physics. We argue that the identification of gaugino masses is the most promising step in this direction. Mass predictions for gauginos are pretty robust and often related to the values of the gauge couplings constants. They might allow a meaningful crosscheck for grand unification, at least in simple schemes like gravity, anomaly or mirage mediation.

Are stellar over-densities in dwarf galaxies the "smoking gun" of triaxial dark matter haloes?

description: We use N-body simulations to study the tidal evolution of globular clusters (GCs) in dwarf spheroidal (dSph) galaxies. Our models adopt a cosmologically motivated scenario in which the dSph is approximated by a static NFW halo with a triaxial shape. For a large set of orbits and projection angles we examine the spatial and velocity distribution of stellar debris deposited during the complete disruption of stellar clusters. Our simulations show that such debris appears as shells, isolated clumps and elongated over-densities at low surface brightness (>26 mag/arcsec^2), reminiscent of substructure observed in several MW dSphs. Such features arise from the triaxiality of the galaxy potential and do not dissolve in time. Stellar over-densities reported in several MW dSphs may thus be the telltale evidence of dark matter haloes being triaxial in shape. We explore a number of kinematic signatures that would help to validate (or falsify) this scenario. The mean angular momentum of the cluster debris associated with box and resonant orbits, which are absent in spherical potentials, is null. As a result, we show that the line-of-sight velocity distribution may exhibit a characteristic "double-peak" depending on the oriention of the viewing angle with respect to the progenitor's orbital plane. Kinematic surveys of dSphs may help to detect and identify substructures associated with the disruption of stellar clusters, as well as to address the shape of the dark matter haloes in which dSphs are embedded.

description: This paper provides an in-depth empirical analysis of several evolutionary algorithms on the one-dimensional spin glass model with power-law interactions. The considered spin glass model provides a mechanism for tuning the effective range of interactions, what makes the problem interesting as an algorithm benchmark. As algorithms, the paper considers the genetic algorithm (GA) with twopoint and uniform crossover, and the hierarchical Bayesian optimization algorithm (hBOA). hBOA is shown to outperform both variants of GA, whereas GA with uniform crossover is shown to perform worst. The differences between the compared algorithms become more significant as the problem size grows and as the range of interactions decreases. Unlike for GA with uniform crossover, for hBOA and GA with twopoint crossover, instances with short-range interactions are shown to be easier. The paper also points out interesting avenues for future research.
Re-Examination of Possible Bimodality of GALLEX Solar Neutrino Data

description: The histogram formed from published capture-rate measurements for the GALLEX solar neutrino experiment is bimodal, showing two distinct peaks. On the other hand, the histogram formed from published measurements derived from the similar GNO experiment is unimodal, showing only one peak. However, the two experiments differ in run durations: GALLEX runs are either three weeks or four weeks (approximately) in duration, whereas GNO runs are all about four weeks in duration. When we form 3-week and 4-week subsets of the GALLEX data, we find that the relevant histograms are unimodal. The upper peak arises mainly from the 3-week runs, and the lower peak from the 4-week runs. The 4-week subset of the GALLEX dataset is found to be similar to the GNO dataset. A recent re-analysis of GALLEX data leads to a unimodal histogram.

description: We present in this paper a biometric system of face detection and recognition in color images. The face detection technique is based on skin color information and fuzzy classification. A new algorithm is proposed in order to detect automatically face features (eyes, mouth and nose) and extract their correspondent geometrical points. These fiducial points are described by sets of wavelet components which are used for recognition. To achieve the face recognition, we use neural networks and we study its performances for different inputs. We compare the two types of features used for recognition: geometric distances and Gabor coefficients which can be used either independently or jointly. This comparison shows that Gabor coefficients are more powerful than geometric distances. We show with experimental results how the importance recognition ratio makes our system an effective tool for automatic face detection and recognition.

New two-colour light curves of Q0957+561: time delays and the origin of intrinsic variations

description: We extend the gr-band time coverage of the gravitationally lensed double quasar Q0957+561. New gr light curves permit us to detect significant intrinsic fluctuations, to determine new time delays, and thus to gain perspective on the mechanism of intrinsic variability in Q0957+561. We use new optical frames of Q0957+561 in the g and r passbands from January 2005 to July 2007. These frames are part of an ongoing long-term monitoring with the Liverpool robotic telescope. We also introduce two photometric pipelines that are applied to the new gr frames of Q0957+561. The transformation pipeline incorporates zero-point, colour, and inhomogeneity corrections to the instrumental magnitudes, so final photometry to the 1-2% level is achieved for both quasar components. The two-colour final records are then used to measure time delays. The gr light curves of Q0957+561 show several prominent events and gradients, and some of them (in the g band) lead to a time delay between components of 417 +/- 2 d (1 sigma). We do not find evidence of extrinsic variability in the light curves of Q0957+561. We also explore the possibility of a delay between a large event in the g band and the corresponding event in the r band. The gr cross-correlation reveals a time lag of 4.0 +/- 2.0 d (1 sigma; the g-band event is leading) that confirms a previous claim of the existence of a delay between the g and r band in this lensed quasar. The time delays (between quasar components and between optical bands) from the new records and previous ones in similar bands indicate that most observed variations in Q0957+561 (amplitudes of about 100 mmag and timescales of about 100 d) are very probably due to reverberation within the gas disc around the supermassive black hole.

Flux Vacua Attractors in Type II on SU(3)xSU(3) Structure
Creators: name: Anguelova, Lilia
Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We summarize and extend our work on flux vacua attractors in generalized compactifications. After reviewing the attractor equations for the heterotic string on SU(3) structure manifolds, we study attractors for N=1 vacua in type IIA/B on SU(3)xSU(3) structure spaces. In the case of vanishing RR flux, we find attractor equations that encode Minkowski vacua only (and which correct a previous normalization error). In addition to our previous considerations, here we also discuss the case of nonzero RR flux and the possibility of attractors for AdS vacua.

description: Superconductivity in LaNiPO is disrupted by small (~5%) amounts of non-stoichiometry on the lanthanum site, even though the electronic contribution to the heat capacity increases with increasing non-stoichiometry. All samples also exhibit specific heat anomalies consistent with the presence of ferromagnetic spin fluctuations (Tsf ~ 14 K). Comparison of layered nickel phosphide and nickel borocarbide superconductors reveals different structure-property correlations in the two families.

Gravitino dark matter in hybrid gauge-gravity models
Creators: name: Cerdeno, D. G.
name: Mambrini, Y.

Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We study the phenomenology of generic supergravity models in which gravity mediation naturally competes with gauge mediation as the origin of supergravity-breaking. This class of hybrid models has been recently motivated in string inspired constructions and differs from usual gauge mediated supersymmetry breaking models in having messenger masses of order of the GUT scale. In these scenarios the gravitino can be the lightest supersymmetric particle in wide regions of the parameter space and therefore a potential candidate for dark matter. We investigate this possibility, imposing the WMAP bound on its relic abundance and taking into account constraints from Big Bang nucleosynthesis. We show that in these constructions viable gravitino dark matter can be obtained in specific regions of the parameter space, featuring large values of tan(beta) and where the supersymmetry breaking mechanism is dominated by gauge mediation.

Blackflies (Diptera: Simuliidae) : a problem review and evaluation
Creators: name: Watts, Susan B.
Publisher: name: University of British Columbia
Year: 2010

description: An extensive review herein of world literature on blackflies (Diptera: Simuliidae Latreille) with references extending over nearly two centuries, and addressed to diverse interest groups, has highlighted the importance of these flies, their biological and resource-use impacts, the advances in knowledge concerning them, the gaps in the information, the obstacles to progress, the hazards of applying ill-considered heroic measures to cope with them, and the directions which research might profitably pursue. Needs remain for clearer understanding of the components of blackfly behaviour in general, and at a species level, with due regard to determinant factors in attractance and repellence as these decide proneness to attack. Needs remain for a clearer understanding of the factors of differential and changing physiological reaction of the host to the toxin injected by the flies. Other needs remain for more thorough documentation of resource impacts caused by these insects. A great need remains for more complete understanding of the population ecology of blackflies, as well as their role among primary consumers, and as food organisms themselves, in food chains in benthic ecosystems.

There are five species of Synstrophus (Nikitsky, 1998) distributed in China, Japan, Oriental region, and North America. Nikitsky (1998) mentioned that, based on several characters, S. repandus (Horn) might eventually merit placement in a different genus-group taxon.

Bioenergia ed innovazione nelle aree rurali: la valorizzazione energetica della biomassa forestale attraverso un caso studio
Creators: name: Neri, Tommaso <1978>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2010
Subjects: AGR/01 Economia ed estimo rurale

description: Le politiche di promozione e sostegno delle bioenergie sono state predisposte in relazione al raggiungimento di specifici obiettivi quali non sempre facilmente conciliabili: la riduzione delle emissioni di gas clima alteranti; la diminuzione della dipendenza energetica dai combustibili fossili; la creazione di nuove opportunità per le imprese agricole e forestali; il sostegno allo sviluppo rurale. All’interno del dibattito agricolo-economico la tematica delle bio-energie risulta di estrema attualità: ai potenziali vantaggi si contrappongono le critiche nei confronti della loro sostenibilità ambientale, economica e sociale. La bio-energia può però anche essere interpretata come un esempio di innovazione che coinvolge il settore agricolo e le aree rurali. Obiettivo del presente lavoro è infatti quello di proporre una rilettura del tema delle bioenergie attraverso l’approccio alla tematica  dell’innovazione sviluppato nell’ambito del progetto europeo In-Sight, il quale parte dal presupposto che qualsiasi cambiamento nel sistema di produzione, di consumo e di distribuzione è in grado di generare innovazione. Tale approccio è stato utilizzato per analizzare il processo innovativo che ha condotto alla realizzazione di un impianto di teleriscaldamento a biomasse legnose in Toscana. Il caso studio dimostra come anche nel caso delle bioenergie gli elementi innovativi vadano oltre al di là del solo aspetto tecnologico.

Supersymmetry Phenomenology

description: Abstract: Extensions of the minimal supersymmetric standard model (MSSM) gauge group abound in the literature. Several of these include an additional U(1)X gauge group. Chiral fermions’ charge assignments under U(1)X are constrained to cancel local anomalies in the extension and they determine the structure and phenomenology of it. We provide all anomaly-free charge assignments up to a maximum absolute charge of Qmax = 10, assuming that the chiral superfield content of the model is that of the MSSM plus up to three Standard Model (SM) singlet superfields. The fermionic components of these SM singlets may play the rôle of right-handed neutrinos, whereas one of the scalar components may play the rôle of the flavon, spontaneously breaking U(1)X. Easily scanned lists of the charge assignments are made publicly available on Zenodo. For the case where no restriction is placed upon Qmax, we also provide an analytic parameterisation of the general solution using simple techniques from algebraic geometry.

description: The possible symmetries of the biaxial nematic phase are examined against the implications of the presently available experimental results. Contrary to the widespread notion that biaxial nematics have orthorhombic symmetry, our study shows that a monoclinic ($C_{2h}$) symmetry is more likely to be the case for the recently observed phase biaxiality in thermotropic bent-core and calamitc tetrapode nematic systems. The methodology for differentiating between the possible symmetries of the biaxial nematic phase by NMR and by IR spectroscopy measurements is presented in detail. The manifestations of the different symmetries on the alignment of the biaxial phase are identified and their implications on the measurement and quantification of biaxiality as well as on the potential use of biaxial nematic liquid crystals in electro-optic applications are discussed.
