description: We investigate the dependence of the photogalvanic response of a multi-Weyl semimetal on its topological charge, tilt, and chemical potential. We derive analytical expressions for the shift and injection conductivities for tilted charge-$n$ Weyl points $(n=1,2,3)$ using a low energy two-band effective Hamiltonian. For double-Weyl semimetals, we also compute the response from two-band and four-band tight-binding models with broken time-reversal symmetry to study the effect of band bending and the contributions from higher bands. We find a significant deviation in the responses obtained from the effective low-energy continuum model and more realistic four-band continuum and tight-binding models. We analyze several different limits of these models. We describe the nature of the deviations and provide estimates of their dependence on the frequency and other model parameters. Our analysis provides a simple explanation for the first-principle calculation based frequency dependence of the injection current in SrSi$_2$. Additionally, we find interesting parameter regimes where the frequency dependence of the non-linear optical response can be directly used to probe the type-I/type-II nature of the Weyl cone. We obtain analytical results for the charge-4 Weyl semimetal by reducing the original problem involving a triple $k$-space integral to one with only a double integral. This simplification allows us to extract all relevant information about the nature of its second-order dc response and the precise condition for observing circular photogalvanic effect quantization. The semi-analytical approach presented here can also be extended to a systematic study of second harmonic generation and first-order optical conductivity in charge-4 Weyl semimetals.

Biomimetic synthesis of poly(propylene-fumarate)-calcium phosphate composites for tissue engineering
Creators: name: Hakimi Mehr, Dorna
Publisher: name: University of British Columbia
Year: 2010

description: A novel in-situ co-precipitation process for the synthesis of poly(propylene-fumarate)-calcium phosphate composites was developed. In this process the calcium phosphate phase nucleates and grows in the presence of poly(propylene-fumarate) (PPF), in a novel two-solvent system including tetrahydrofuran (THF) and water. It was found that the presence of the organic solvent (THF) does not affect the phase evolution of the calcium phosphate. Both in the presence and absence of THF crystalline dicalcium phosphate dihydrate (DCPD, brushite) and poorly crystalline hydroxyapatite (HAp) form, and transform to crystalline HAp after 24 hours of synthesis time. Contrary to the organic solvent, PPF has a significant influence on the calcium phosphate phase that forms in its presence. It is found that PPF provides a template for the formation of the calcium phosphate phase through a coordination bond between the calcium ion and the carbonyl group of the polymer. As a result of this templating, hydroxyapatite can form in a significantly shorter period of time (~1 hr) compared to the system where PPF is not present (24 hrs). The nature of the calcium phosphate phase that forms in the presence of PPF depends on the molecular weight and concentration of PPF. High concentration of PPF in the composite (e.g. 80%) stabilizes an amorphous calcium phosphate (ACP) phase and hinders its transformation to crystalline apatite, while low concentration of PPF (e.g. 5%) promotes the formation of crystalline apatite. Higher molecular weight PPF (Mw = 4500) is found to be more efficient in stabilizing the amorphous phase compared to lower molecular weight PPF (Mw = 1800). While high molecular weight PPF stabilizes ACP, low molecular weight PPF promotes its conversion to crystalline apatite. TEM observations revealed that flake-like hydroxyapatite crystals form in the absence of PPF while spherical ACP particles form in a composite containing 80% PPF. The ACP nano-particles (50-100 nm in diameter) are homogeneously distributed within the PPF matrix. The PPF-calcium phosphate composite can crosslink into a 3D structure by UV irradiation.

description: Informational and communication technologies change traditional business models and provide new value chains. Banking, one of the last which has not been destroyed by new digital revolution, is facing unprecedented changes. The new generation do not see banks as part of their ecosystem and their lifestyles. They do not need the bank but felicitous banking services only. Known as FinTech companies provide attractive alternative banking solutions and could convert traditional banks into archaic commodities. On the other hand, banks cannot quickly adapt to the new conditions due to many restricting factors and limitations, they are scared to lose out business in competitive struggle. This research addresses the systemic issues within the banking, highlights it weaknesses and how FinTech cope it using their opportunities to create new banking services. It outlines bank's strategic solutions for a long-term sustainable growth. To sum up my research, I concluded that strategically for our retail bank it is necessary to move in several directions: ' To evolve the new type of lending with a view to bridle the new disruptive crowdfunding trend and attracting new FinTech teams; ' To investigate the evolution of the new disruptive technologies as blockchain, trying to implement projects based on it and be ready for quick adaptation in the future; Transform current business model towards open innovation and open API economy. Research hypothesis that traditional banks will be replaced by banks of a new generation, think and act as FinTech and with FinTech, was confirmed. In the competitive struggle between banks and FinTech companies will win a partnership. Over the next few years FinTech banks will displacing traditional business model and follow the principles of flexibility, openness, and customer focus. This banks in the mobile customer's gadget will operate as a platform with any kind of digital banking services from different players. Research clearly indicated that this is the final call for banking leaders to examine the opportunities arising out of the combination of three elements: digital penetration, FinTech potential and extremely upping value of an open innovation, and to intend the jump to the new business paradigm.

description: In this study, attempts have been made to identify novel inhibitor(s) of SdiA (a homolog of LuxR transcription regulator) of Klebseilla pneumoniae using various computational techniques. 4LFU was used as a template to model the structure of SdiA. ProCheck, Verify3D, Ramachandran plot scores and ProSA-Web confirmed the good quality of the model as the root mean square deviation (RMSD) between SdiA model, and 4LFU template was estimated to be 0.21 Å. The secondary structural contents of SdiA model were predicted using PDBsum. The only binding site of SdiA was identified (area = 523.083 Å2 and volume = 351.044 Å3) using CASTp. Molecular docking at three different levels [high throughput virtual screening, standard-precision (SP) and extra-precision (XP) dockings] with increasingly stringent conditions was performed using Glide on Selleck’s express pick library (L3600). A total of 61 ligands were found to bind with high affinities to the active site of SdiA. Further, the effect of solvent on protein-ligand interaction was evaluated by performing molecular mechanics-general born surface area (Prime/MM-GBSA). On the basis of Prime/MM-GBSA score, molecular dynamics simulation (50 ns) was performed on the ligand (WAY-390139-A) showing lowest binding energy to confirm the stability of protein-ligand complex. Docking energy and the corresponding binding affinity of WAY-390139-A towards SdiA were estimated to be –13.005 kcal mol–1 and 3.46 × 109 M−1, respectively. Our results confirm that WAY-390139-A binds at the autoinducer binding site of SdiA with high affinity and stability and can be further exploited as potential drug against K. pneumoniae after experimental validation.

description: We compute energies and energy densities of static electromagnetic flux tubes in three and four spacetime dimensions. Our calculation uses scattering data from the potential induced by the flux tube and imposes standard perturbative renormalization conditions. The calculation is exact to one-loop order, with no additional approximation adopted. We embed the flux tube in a configuration with zero total flux so that we can fully apply standard results from scattering theory. We find that upon choosing the same on-shell renormalization conditions, the functional dependence of the energy and energy density on the parameters of the flux tube is very similar for three and four spacetime dimensions. We compare our exact results to those obtained from the derivative and perturbation expansion approximations, and find good agreement for appropriate parameters of the flux tube. This remedies some puzzles in the prior literature.

description: This master thesis is aimed to investigate the optimal manufacturing production and financial profit in an industrial environment using mobile robots instead of human operators. The broader research question I aim to answer in this paper is - a method for evaluation of the financial investment for implementing mobile robots in manufacturing. Theoretical method and practical model that will help the potential users of mobile robots to estimate the startup cost and risk in the initiation phase of the project. A scenario of ten different manufacturing processes for manual and autonomous production is created to benchmark the manual and automated manufacturing line. Multiple mobile robots that are programmed to work without human supervision in a synchronized manufacturing process to reduce total cost and improve productivity. The goal is to present robot make robot manufacturing process, without any human intervention. Household mobile robot is the product of the manufacturing process. The paper focus on the startup investment and returns for each scenario for a five-year period. I have referred to different literature to assess various methodological approaches and adapt them to my proposed work. The technical and financial benefits, productivity and customer satisfaction are presented through manufacturing radar chart tool. Throughout the thesis, I have explored the impact of mobile robots and automation to business and people. The effect of automation toward the labor rate and unemployment. The feedback from the public and the organizations that are using or planning to use robots. The future of automation for the next generation and a brief look one hundred years ahead. This study has been a challenging and valuable learning experience for me. I believe that my master thesis will have some significant takeaways for mobile robots and automation in manufacturing.

description: Human movements are both an area of intense study and the basis of many applications such as character animation. For many applications, it is crucial to identify movements from videos or analyze datasets of movements. Here we introduce a new human Motion and Video dataset MoVi, which we make available publicly. It contains 60 female and 30 male actors performing a collection of 20 predefined everyday actions and sports movements, and one self-chosen movement. In five capture rounds, the same actors and movements were recorded using different hardware systems, including an optical motion capture system, video cameras, and inertial measurement units (IMU). For some of the capture rounds, the actors were recorded when wearing natural clothing, for the other rounds they wore minimal clothing. In total, our dataset contains 9 hours of motion capture data, 17 hours of video data from 4 different points of view (including one hand-held camera), and 6.6 hours of IMU data. In this paper, we describe how the dataset was collected and post-processed; We present state-of-the-art estimates of skeletal motions and full-body shape deformations associated with skeletal motion. We discuss examples for potential studies this dataset could enable.

description: Across a faceted (100)/(110) interface between two d-wave-superconductors the structure of the superconducting order parameter leads to an alternating sign of the local Josephson coupling. Describing the Cooper pair motion along and across the interface by a one-dimensional boson lattice model, we show that a small attractive interaction between the bosons boosts boson binding at the interface -- a phenomenon, which is intimately tied to the staggered sequence of 0- and Pi-junction contacts along the interface. We connect this finding to the recently observed h/4e oscillations in (100)/(110) SQUIDS of cuprate superconductors.

Revisiting longitudinal plasmon-axion conversion in external magnetic fields

description: In the presence of an external magnetic field the axion and the photon mix. In particular, the dispersion relation of a longitudinal plasmon always crosses the dispersion relation of the axion (for small axion masses), thus leading to a resonant conversion. Using thermal field theory we concisely derive the axion emission rate, applying it to astrophysical and laboratory scenarios. For the Sun, depending on the magnetic field profile plasmon-axion conversion can dominate over Primakoff production at low energies ($\lesssim 200\,$eV). This both provides a new axion source for future helioscopes and, in the event of discovery, would probe the magnetic field structure of the Sun. In the case of white dwarfs (WDs), plasmon-axion conversion provides a pure photon coupling probe of the axion, which may contribute significantly for low-mass WDs. Finally we rederive and confirm the axion absorption rate of the recently proposed plasma haloscopes.

Effects of Coulomb interactions on the splitting of luminescence lines

description: We study the splitting between the right-hand and left-hand circularly polarized luminescence lines in a quantum dot under relatively weak confinement regime and resonant high-power excitation. When the dot is populated with an even number of electron-hole pairs (biexciton and higher excitations), the splitting measures basically the Zeeman energy. However, in the odd number of pairs case, we have, in addition to the Zeeman and Overhauser shifts, a contribution to the splitting coming from Coulomb interactions. This contribution is of the order of a few meV, and shows distinct signatures of shell-filling in the quantum dot.

Multi-level Delumping Strategy for Thermal Enhanced Oil Recovery Simulations at Low Pressure
Creators: name: Cremon, Matthias A.

Publisher: name: arXiv
Year: 2020
Subjects: subject: Computational Physics (physics.comp-ph)
subject: FOS: Physical sciences

description: We present a multi-level delumping method suitable for thermal enhanced oil recovery processes, for which hydrocarbon components are vaporized under high temperatures, move downstream in the gas phase and condense back to the liquid phase. To reduce the computational cost, it is standard practice to reduce the number of (pseudo-)components used in thermal reservoir simulation. Depending on the number and type of hydrocarbon pseudo-components retained in the simulations, we may not be able to capture the correct displacement due to large errors in the lumped phase behavior (flash) computations. We address that problem through a multi-level method: we use data obtained from a short simulation using the most detailed fluid description available, and leverage that information to guide a delumping process. We use temperature as a proxy variable for composition, and select reference temperatures. We extract the corresponding reference compositions from the detailed run and use them to extend the lumped pseudo-components to an approximate detailed composition. We test our method using six heavy oil samples, and under two different recovery processes: hot nitrogen injection and in-situ combustion (air injection and exothermic oxidation reactions). The average error on the liquid mole fraction is reduced by 4-12 times (depending on the oil samples) compared to the flash using pseudo-components, and the maximum error by 6-48 times. We illustrate that the method is amenable to manually adding more information about the physics of some oil samples. We also discuss how to efficiently pick the reference temperatures. For uniformly sampled temperatures (between a minimum and maximum temperature), we conduct a sensitivity study which led us to use six temperatures. We ran both local (Pattern Search, PS) and global (Particle Swarm Optimization, PSO) gradient-free optimization methods.

description: We report the detection of narrow Fe XXV and Fe XXVI X-ray absorption lines at 6.68 +/- 0.04 keV and 6.97 +/- 0.05 keV in the persistent emission of the dipping low-mass X-ray binary 4U 1323-62 during a 2003 January XMM-Newton observation. These features are superposed on a broad emission feature centered on 6.6 {+0.1}{-0.2} keV. During dipping intervals the equivalent width of the Fe XXV feature increases while that of the Fe XXVI feature decreases, consistent with the presence of less strongly ionized material in the line-of-sight. As observed previously, the changes in the 1.0-10 keV spectrum during dips are inconsistent with a simple increase in absorption by cool material. However, the changes in both the absorption features and the continuum can be modeled by variations in the properties of an ionized absorber. No partial covering of any component of the spectrum, and hence no extended corona, are required. From persistent to deep dipping the photo-ionization parameter, Xi, expressed in erg cm s^{-1}, decreases from log(Xi) of 3.9 +/- 0.1 to log(Xi) of 3.13 +/- 0.07, while the equivalent hydrogen column density of the ionized absorber increases from (3.8 +/- 0.4) 10^{22} atoms cm^{-2} to (37 +/- 2) 10^{22} atoms cm^{-2}. Since highly-ionized absorption features are seen from many other dip sources, this mechanism may also explain the overall changes in X-ray spectrum observed during dipping intervals from these systems.

description: Small and Medium Enterprises (SMEs) are very eager to innovate and can often be more agile when adopting new processes. The problem we see is that in many cases the implementation of new process that aim to drive innovation are not systematically structured. Innovation has become a very important and broad topic and there is a lot of information on the subject matter, which makes it difficult to choose the correct literature and methodology to make an efficient adoption of an innovative culture. SMEs have usually limited budgets for such activities and big consulting firms (Price Waterhouse Coopers or Deloitte) are often too robust and costly, not only because of the infrastructure they have, but also because their projects are complex and require many resources. Our proposal to solve this problem is to build a framework that will offer a stage- based methodology assisting the development of an open innovation driven culture within an enterprise. This framework, which we called 'Cadence of Innovation System' (CIS), recommends an assessment that identifies the current innovation efforts of the enterprise at an early integration stage (stage 0). The first stage is the implementation of an 'innovation system' (systematic and repeatable approach to control a company's allocation of time and resources) on a project basis. The second stage uses the innovation system adopted in the first stage on a strategic basis and with significant effort placed on communication. The third stage continues the systematic approach in line with the first and second stage by emphasising communication and allows for an enterprise to start acting with an innovation culture. This framework, on top of all these stages, encourages the enterprise to systematically and continuously revisit all the levels of the system, including the assessment stage. CIS aims to bring up the discussion of the needed leadership style to manage an organization that has the capability to exploit and explore ideas (ambidexterity), to promote an inclusive organization that empowers employees (contextual environment) and that has a customer-oriented Vision.

description: A klímaváltozás, pontosabban a cikkben is bizonyított felmelegedési tendencia, az aszályos évek és az időjárási anomáliák gyakorisága tényként fogadható el. Éppen ezért mind az aszályra, mind a vízbőségre szükséges felkészülni. Ennek eszköztára sokszínű, akárcsak a klímaváltozás jelenségei. Mindenekelőtt az aszály megelőzésének és kártételének enyhítése az elsőrendű stratégiai rangú feladat. Így a talajművelés megváltoztatása, a művelési ágak arányváltoztatásai, új szárazságtűrő növényfajták termelésbe vonása, az öntözés és melioráció fejlesztése indokolt. A vízbőség elleni védekezésben az ismert agrotechnikai és műszaki beavatkozások széles körű alkalmazása jelenti a megoldást. A stratégiát jól szolgálják az agrár-környezetvédelmi programban megfogalmazott törekvések is. Szükséges továbbá az információs rendszer finomítása és a biztosítási rendszer átalakítása. A klímaváltozásra való felkészülés a külön féle hazai és EU pénzügyi forrásokra támaszkodhat. -------------- Climatic change - or, more exactly, the trend of warming, the frequency of years of draught, and anomalies of the weather, the existence of which is proven also by the present paper - can be accepted as a matter of fact. Therefore arrangements for the control of both draught and excess precipitation must be made. There are manifold means for this purpose, just as the phenomena of the climatic change are very various too. The main strategic task is to prevent draught or at least reduce the damage caused by it. Such measures are recommended for this purpose as: the alteration of tillage; the modification of the ratio of cultivated crops; the introduction of new plant varieties resistant to draught; and the development of irrigation and amelioration. Endeavours formulated in the programme of environ mental protection in agriculture are also very helpful in respect of the strategy in question. Another task is to improve the information system and transform the assurance system. Preparations for the climatic change can be based on diverse (both domestic and EU) financial resources.

description: We study the two main corrections generally applied to narrow-band H-alpha fluxes from galaxies in order to convert them to star formation rates, namely for NII contamination and for extinction internal to the galaxy. From an imaging study using narrow-band filters, we find the NII and H-alpha emission to be differently distributed. In most disk star formation regions the NII fraction is small, whereas some galaxies display a diffuse central component which can be dominated by NII emission. We consider explanations for variations in the NII/H-alpha ratio, including metallicity variations and different excitation mechanisms. We then estimate the extinction towards star formation regions in spiral galaxies, firstly using Br-gamma/H-alpha line ratios. We find that extinction values are larger in galaxy nuclei than in disks, and that there is no evidence for heavily dust-embedded regions emerging in the near-IR. We use optical emission line data from the literature to show only a moderate dependence of extinction on inclination, consistent with broad-band photometric studies; typical extinctions are smaller for late-type dwarfs than for spiral types. Finally, we show that the application of type-dependent extinction corrections significantly improves the agreement between star formation rates from H-alpha and IRAS fluxes. This agreement argues against star formation in normal galaxies being dominated by heavily dust-embedded components.

description: Throughout its history, Operational Research has evolved to include a variety of methods, models and algorithms that have been applied to a diverse and wide range of contexts. This encyclopedic article consists of two main sections: methods and applications. The first aims to summarise the up-to-date knowledge and provide an overview of the state-of-the-art methods and key developments in the various subdomains of the field. The second offers a wide-ranging list of areas where Operational Research has been applied. The article is meant to be read in a nonlinear fashion. It should be used as a point of reference or first-port-of-call for a diverse pool of readers: academics, researchers, students, and practitioners. The entries within the methods and applications sections are presented in alphabetical order. The authors dedicate this paper to the 2023 Turkey/Syria earthquake victims. We sincerely hope that advances in OR will play a role towards minimising the pain and suffering caused by this and future catastrophes.

description: Capturing innovation is not only a competitive advantage, but also a necessity for corpora-tions around the world. In the past, innovative endeavors were pursued by research and de-velopment (R&D) departments. However, the gleaming days of R&D of being the innova-tion center of a company are fading. Nowadays innovation takes place all over the world and usually can be found within privately held startups. For incumbents to spot innovation outside their corporation¿s fence, corporate venture cap-ital (CVC) is gaining importance as an effective investment method. Formerly, corporations that used CVC as a vehicle to innovation were exclusively based in the United States. How-ever, every year the number of European and Asian companies investing into young entre-preneurs in different countries in the world is raising rapidly. This raises the question of how corporations, that are from culturally distinct countries, con-duct corporate venture capital programs, what are the significant alterations in corporate venture capital and what are the similarities in terms of unit organization and investment activity. Through a survey of 34 corporate venture units from Asia, Europe and North Amer-ica, those questions will be answered. This thesis contributes to the discourse on corporate venture capital by providing a better understanding how this investment method is used in different countries in the world.

description: We report on a low-temperature transport study of a single-gate, planar field-effect device made from a free-standing, wurtzite-crystalline InAs nanosheet. The nanosheet is grown via molecular beam epitaxy and the field-effect device is characterized by gate transfer characteristic measurements and by magnetic field orientation dependent transport measurements. The measurements show that the device exhibits excellent electrical properties and the electron transport in the nanosheet is of the two-dimensional nature. Low-field magnetoconductance measurements are performed for the device at different gate voltages and temperatures, and the characteristic transport lengths, such as phase coherent length, spin-orbit length and mean free path, in the nanosheet are extracted. It is found that the spin-orbit length in the nanosheet is short, on the order of 150 nm, demonstrating the presence of strong spin-orbit interaction in the InAs nanosheet. Our results show that epitaxially grown, free-standing, InAs nanosheets can serve as an emerging semiconductor nanostructure platform for applications in spintronics, spin qubits and planar topological quantum devices.

description: In this study, attempts have been made to identify novel inhibitor(s) of SdiA (a homolog of LuxR transcription regulator) of Klebseilla pneumoniae using various computational techniques. 4LFU was used as a template to model the structure of SdiA. ProCheck, Verify3D, Ramachandran plot scores and ProSA-Web confirmed the good quality of the model as the root mean square deviation (RMSD) between SdiA model, and 4LFU template was estimated to be 0.21 Å. The secondary structural contents of SdiA model were predicted using PDBsum. The only binding site of SdiA was identified (area = 523.083 Å2 and volume = 351.044 Å3) using CASTp. Molecular docking at three different levels (high throughput virtual screening, standard precision (SP) and extra precision (XP) dockings) with increasingly stringent conditions was performed using Glide on Selleck’s express pick library (L3600). A total of 61 ligands were found to bind with high affinities to the active site of SdiA. Further, the effect of solvent on protein-ligand interaction was evaluated by performing molecular mechanics-general born surface area (Prime/MM-GBSA). On the basis of Prime/MM-GBSA score, molecular dynamics simulation (50 ns) was performed on the ligand (WAY-390139-A) showing lowest binding energy to confirm the stability of protein-ligand complex. Docking energy and the corresponding binding affinity of WAY-390139-A towards SdiA were estimated to be -13.005 kcal/mol and 3.46 × 109 M−1, respectively. Our results confirm that WAY-390139-A binds at the autoinducer binding site of SdiA with high affinity and stability, and can be further exploited as potential drug against K. pneumoniae after experimental validation.

description: Roles of instanton induced interactions (III) in the masses of pentaquark baryons, Theta^+ (J=1/2 and 3/2) and Xi^{--}, and a dibaryon, H, are discussed using the MIT bag model. It is shown that the two-body terms in III give a strong attraction mainly due to the increase of the number of pairs in multi-quark systems. In contrast, the three-body $u$-$d$-$s$ interaction is repulsive. It is found that III lowers the mass of negative-parity Theta^+ as much as 100 MeV from the mass predicted by the bag model without III.

description: The domain size dependence of piezoelectric properties of ferroelectrics is investigated using a continuum Ginzburg-Landau model that incorporates the long-range elastic and electrostatic interactions. Microstructures with desired domain sizes are created by quenching from the paraelectric phase by biasing the initial conditions. Three different two-dimensional microstructures with different sizes of the $90^{o}$ domains are simulated. An electric field is applied along the polar as well as non-polar directions and the piezoelectric response is simulated as a function of domain size for both cases. The simulations show that the piezoelectric coefficients are enhanced by reducing the domain size, consistent with recent experimental results of Wada and Tsurumi (Brit. Ceram. Trans. {\bf 103}, 93, 2004) on domain engineered $BaTiO_{3} $

description: Observations of V404 Cyg performed with the Westerbork Synthesis Radio Telescope at four frequencies, over the interval 1.4-8.4 GHz, have provided us with the first broadband radio spectrum of a `quiescent' stellar mass black hole. The measured mean flux density is of 0.35 mJy, with a spectral index alpha=+ 0.09\pm0.19$ (such that S_nu \propto nu^{alpha}). Synchrotron emission from an inhomogeneous partially self-absorbed outflow of plasma accounts for the flat/inverted radio spectrum, in analogy with hard state black hole X-ray binaries, indicating that a steady jet is being produced between a few 10^{-6} and a few per cent of the Eddington X-ray luminosity.

On ${\cal N}{=}\,2$ supersymmetric Ruijsenaars-Schneider models

description: We construct an ${\cal N}{=}\,2$ supersymmetric extension of $n$-particle Ruijsenaars-Schneider models. The guiding feature is a deformation of the phase space. The supercharges have a "free" form linear in the fermions but produce an interacting four-fermion Hamiltonian. A field-dependent unitary transformation maps to standard fermions obeying conventional Poisson brackets. In this frame, the supercharges and Hamiltonian have long "fermionic tails". We also comment on previous attempts in this direction.
