description: We study a K-theoretic characteristic class of singular varieties, namely the equivariant motivic Chern class. We prove that the motivic Chern class is characterized by an axiom system inspired by that of "K-theoretic stable envelopes," recently defined by Okounkov and studied in relation with quantum group actions on the K-theory algebra of moduli spaces. We also give explicit formulas for the equivariant motivic Chern classes of Schubert cells and matrix Schubert cells. Lastly, we calculate the equivariant motivic Chern class of the orbits of the A2 quiver representation, which yields formulas for the motivic Chern classes of determinantal varieties and more general degeneracy loci.

description: This research explores a 'border crossing' exercise intent on seeking a convergence (where possible) between two similar frameworks (complexity theory and social ecology) for understanding and progressing physical education using holistic and systems-based concepts. Researcher narratives are presented here as part of that research. These serve to position the two protagonists backgrounds and histories as part of a border crossing exercise. Narratives serve to give context to theoretical concepts and support a process of connecting research.

description: We show that if $f$ is an integer-valued function with spectral norm at most $M$ then there are subspaces $V_1,\dots,V_L$ and signs $σ_1,\dots,σ_L \in \{-1,1\}$ such that $f=σ_1 1_{V_1} + \dots + σ_L 1_{V_L}$ where $L < \exp(M^{3+o(1)})$. This note extracts out the argument from arXiv:1610.07092 to the model setting of $\mathbb{F}_2^n$. The hope is that it will clarify the arguments of that paper.

description: We extend quantum models of nanowire surface scattering to incorporate bulk resistivity and extract an expression for the increased resistivity due to surface roughness. To learn how to improve conductivity, we calculate conductivity degradation from individual wavelengths of surface roughness, and show how these can be convolved to give resistivity for arbitrary surfaces. We review measurements from Cu films and conclude that roughness at short wavelengths (less than 100 nm) dominates scattering, and that primarily specular scattering should be achievable for RMS roughness below about 0.7 nm.

description: The ability to design and synthesize ever more complicated colloidal particles opens the possibility of self-assembling a zoo of complex structures, including those with one or more self-limited length scales. An undesirable feature of systems with self-limited length scales is that thermal fluctuations can lead to the assembly of nearby, off-target states. We investigate strategies for limiting off-target assembly by using multiple types of subunits. Using simulations and energetics calculations, we explore this concept by considering the assembly of tubules built from triangular subunits that bind edge to edge. While in principle, a single type of triangle can assemble into tubules with a monodisperse width distribution, in practice, the finite bending rigidity of the binding sites leads to the formation of off-target structures. To increase the assembly specificity, we introduce tiling rules for assembling tubules from multiple species of triangles. We show that the selectivity of the target structure can be dramatically improved by using multiple species of subunits, and provide a prescription for choosing the minimum number of subunit species required for near-perfect yield. Our approach of increasing the system's complexity to reduce the accessibility of neighboring structures should be generalizable to other systems beyond the self-assembly of tubules.

The Infrared Luminosity Function of AKARI 90$μ$m Galaxies in the Local Universe

Year: 2017
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: Local infrared (IR) luminosity functions (LFs) are necessary benchmarks for high-redshift IR galaxy evolution studies. Any accurate IR LF evolution studies require accordingly accurate local IR LFs. We present infrared galaxy LFs at redshifts redshifts of $z \leq 0.3$ from AKARI space telescope, which performed an all-sky survey in six IR bands (9, 18, 65, 90, 140 and 160 micron) with 10 times better sensitivity than its precursor IRAS. Availability of 160 micron filter is critically important in accurately measuring total IR luminosity of galaxies, covering across the peak of the dust emission. By combining data from Wide-field Infrared Survey Explorer (WISE), Sloan Digital Sky Survey (SDSS) Data Release 13 (DR13), 6-degree Field Galaxy Survey (6dFGS) and the 2MASS Redshift Survey (2MRS), we created a sample of 15,638 local IR galaxies with spectroscopic redshifts, factor of 7 larger compared to previously studied AKARI -SDSS sample. After carefully correcting for volume effects in both IR and optical, the obtained IR LFs agree well with previous studies, but comes with much smaller errors. Measured local IR luminosity density is $Ω_{IR}=$ 1.19$\pm$0.05 $\times 10^{8}$ L$_{\odot}$ Mpc$^{-3}$. The contributions from luminous infrared galaxies and ultra luminous infrared galaxies to IR are very small, 9.3 per cent and 0.9 per cent, respectively. There exists no future all sky survey in far-infrared wavelengths in the foreseeable future. The IR LFs obtained in this work will therefore remain an important benchmark for high-redshift studies for decades.

An Unsplit Godunov Method for Ideal MHD via Constrained Transport in Three Dimensions

Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)

description: We present a single step, second-order accurate Godunov scheme for ideal MHD which is an extension of the method described by Gardiner & Stone (2005) to three dimensions. This algorithm combines the corner transport upwind (CTU) method of Colella for multidimensional integration, and the constrained transport (CT) algorithm for preserving the divergence-free constraint on the magnetic field. We describe the calculation of the PPM interface states for 3D ideal MHD which must include multidimensional ``MHD source terms'' and naturally respect the balance implicit in these terms by the ${\bf\nabla\cdot B}=0$ condition. We compare two different forms for the CTU integration algorithm which require either 6- or 12-solutions of the Riemann problem per cell per time-step, and present a detailed description of the 6-solve algorithm. Finally, we present solutions for test problems to demonstrate the accuracy and robustness of the algorithm.

description: The Cassini spacecraft found a new and unique ring that shares the trajectory of Janus and Epimetheus, co-orbital satellites of Saturn. Performing image analysis, we found this to be a continuous ring. Its width is between 30% and 50% larger than previously announced. We also verified that the ring behaves like a firefly. It can only be seen from time to time, when Cassini, the ring and the Sun are arranged in a particular geometric configuration, in very high phase angles. Otherwise, it remains "in the dark", not visible to Cassini's cameras. Through numerical simulations, we found a very short lifetime for the ring particles, less than a couple of decades. Consequently, the ring needs to be constantly replenished. Using a model of particles production due to micrometeorites impacts on the surfaces of Janus and Epimetheus, we reproduce the ring, explaining its existence and the "firefly" behavior.

description: We implement Grover's quantum search algorithm on a nuclear spin chain quantum computer, taking into Ising type interactions between nearest and second nearest neighbours into account. The performance of the realisation of the algorithm is studied by numerical simulations with four spins. We determine the temporal behaviour of the fidelity during the algorithm, and we compute the final fidelity as a function of the Rabi frequency. For the latter, we obtained pronounced maxima at frequencies which fulfil the condition of the (2πk)-method with respect to the second nearest neighbour interactions.

Bidirectional-Stability Breaking in Thermodynamic Average for Classical Discrete Systems

Year: 2018
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: For classical systems, expectation value of macroscopic property in equilibrium state can be typically provided through thermodynamic (so-called canonical) average, where summation is taken over possible states in phase space (or in crystalline solids, it is typically approximated on cofiguration space). Although we have a number of theoretical approaches enabling to quantitatively estimate equilibrium properties by applying given potential energy surface (PES) to the thermodynamic average, it is generally unclear whether PES can be stablly, inversely determined from a given set of properties. This essentially comes from the fact that bidirectional stability characters of thermodynamic average for classical system is not sufficiently understood so far. Our recent study reveals that for classical discrete system, this property for a set of microscopic states satisfying special condition can be well-characterized by a newly-introduced concept of anharmonicity in the structural degree of freedom of D, where these states are expected to be stably inversed to underlying PES, known without any thermodynamic information. However, it is still quantitatively unclear how the bidirectional stability character is broken inside the configuration space. Here we show that the breaking in bidirectional stability for thermodynamic average is quantitatively formulated: We find that the breaking is mainly dominated by the sum of divergence and Jacobian of vector field D in configuration space, which can be fully known a priori only from geometric information of underlying lattice, without using any thermodynamic information such as energy or temperature.

description: Spin correlations and fluctuations in the 3d-transition-metal-based icosahedral quasicrystal Zn-Fe-Sc have been investigated by neutron scattering using polycrystalline samples. Magnetic diffuse scattering has been observed in the elastic experiment at low temperatures, indicating development of static short-range-spin correlations. In addition, the inelastic scattering experiment detects a $Q$-independent quasielastic signal ascribed to single-site relaxational spin fluctuations. Above the macroscopic freezing temperature $T_{\rm f} \simeq 7$ K, the spin relaxation rate shows Arrhenius-type behavior, indicating thermally activated relaxation process. In contrast, the relaxation rate remains finite even at the lowest temperature, suggesting a certain quantum origin for the spin fluctuations below $T_{\rm f}$.

description: Abstract

Biodiesel is a renewable, alternative green fuel from sources such as vegetable oils and animal fats. In the present study, Albizia lebbeck (Albizia) seeds were used as a, low cost, non-edible feedstock for biodiesel production. This study aimed to employ the Accelerated reactive extraction (solvent-assisted in situ transesterification) approach for biodiesel synthesis, which involves simultaneous solvent extraction and transesterification in single step. In current study, dichloromethane (DCM) was used as a co-solvent to increase the miscibility of oil in methanol because methanol is a poor solvent for triglycerides, leading to an increase in biodiesel yield and faster completion of the reaction. Our results demonstrate that this method is a simple and rapid method for biodiesel production. Therefore, this approach can make biodiesel synthesis economically viable, involving fewer processing steps. A statistical optimization technique based on the Box-Behnken design (BBD) of response surface methodology (RSM) was employed to achieve the maximum product yield by optimizing process parameters such as reaction time, temperature, molar ratio (methanol to seed), and catalyst amount. The results of optimization revealed that 300 minutes, 70 °C, 21:1 and 3.5% wt. of conc. H2SO4 were optimized process parameters under which about 98% biodiesel yield could be achieved. The analysis of variance results showed that reaction time, temperature, Catalyst concentration, interaction of temperature-time and time-molar ratio were the most significant parameters. Gas chromatography (GC-FID) results indicated that the major fatty acids in ALO were Linoleic acid (42%) and oleic acid (27%).

description: Ivanov-Anderson (IA) model (and an earlier treatment by Kubo) envisages a decay of the orientational correlation by random but large amplitude molecular jumps, as opposed to infinitesimal small jumps assumed in Brownian diffusion. Recent computer simulation studies on water and supercooled liquids have shown that large amplitude motions may indeed be more of a rule than exception. Existing theoretical studies on jump diffusion mostly assume an exponential (Poissonian) waiting time distribution for jumps, thereby again leading to an exponential decay. Here we extend the existing formalism of Ivanov and Anderson to include an algebraic waiting time distribution between two jumps. As a result, the first and second rank orientational time correlation functions show the same long time power law, but their short time decay behavior is quite different. The predicted Cole-Cole plot of dielectric relaxation reproduces various features of non-Debye behaviour observed experimentally. We also developed a theory where both unrestricted small jumps and large angular jumps coexist simultaneously. The small jumps are shown to have a large effect on the long time decay, particularly in mitigating the effects of algebraic waiting time distribution, and in giving rise to an exponential-like decay, with a time constant, surprisingly, less than the time constant that arises from small amplitude decay alone.

description: In this work Spectral feature MFCC is considered for high accuracy, for Prosody feature Pitch is considered and concatenating with other two different features Cepstrum and DWT and this combination is called as Emotion- Specific Feature Set. A remarkable study is being done in the current years for improving human machine interaction on Speech Emotion Recognition. Speech contains a wealth of details about the Speaker's age, gender, and emotional condition.The challenging task of recognising a single emotion from a speaker is known as emotion recognition. The database under consideration is Telugu-Database, which is prompted by two male and female speakers and includes four emotions: happy, angry, sad, and neutral. To identify the corresponding emotion, different combinations of features are used, and these features are referred to as Emotion-specific features. The rate of combination identification is improved when these features are taken into account. The function information is extracted using the features DWT, Cepstrum, MFCC, and Pitch. After feature extraction, a back-propagation neural network algorithm is used to classify the data, and the results are then evaluated. The study concluded that by increasing number of nodes in the network and number of iterations the recognition rate is above 90%, the combinations of feature sets will give better emotion recognition rate than individual feature sets and the feature set combination DWT+Pitch+Cepstrum produced the individual emotion recognition rate above 95%.

description: Im Rahmen des Projekts AUTOtech.agil haben sich 21 Universitäten und Unternehmen mit dem Ziel zusammengeschlossen, das Mobilitätssystem der Zukunft in Form einer offenen Architektur zu entwerfen. Ein Bestandteil des Projekts, der am Fachgebiet Fahrzeugtechnik der Technischen Universität Darmstadt erarbeitet wird, ist die Entwicklung einer Niedriggeschwindigkeitsfunktion (NGF). Diese soll in der Lage sein, verschiedene Anwendungsfälle im Niedriggeschwindigkeitsbereich mit einer entkoppelten Struktur von geringer Komplexität zu realisieren.
Neben einer eigenen Sensorik ist auch eine globale Trajektorienplanung ein Bestandteil der NGF. Diese berechnet übergeordnete Trajektorien in unstrukturierten Umgebungen wie beispielsweise Parkplätzen oder verkehrsberuhigten Bereichen. Um die unstrukturierten Umgebungen in einer Form abzubilden, die für die Trajektorienplanung geeignet ist, wird im Rahmen dieser Arbeit eine automatisierte Methode entwickelt und implementiert, die Informationen einer hochgenauen Karte verwendet und aus ihnen ein statisches Umgebungsmodell generiert.
Basierend auf den Anforderungen eines graphbasierten Trajektorienplaners und denen einer unstrukturierten Umgebung wird eine semantische Rasterkarte als Darstellungsform ausgewählt. Der gesamte Raum der Umgebung wird dabei abgebildet und kategorisiert, um auch Ausnahmesituation wie beispielsweise Parkvorgänge zu realisieren. Als hochgenaues Kartenformat zur Implementierung des Konzepts, wird das in der Forschung weit verbreitete Format Lanelet2 gewählt. Lanelet2 bietet neben flexiblen Darstellungsmöglichkeiten für unstrukturierte Umgebungen auch einen Quellcode, der frei verfügbar ist und somit die Umsetzung eigener Projekte erleichtert.
Implementiert wird die Methode zur automatisierten Ableitung eines statischen Umgebungsmodells Mithilfe der Programmiersprache Python. Zur Interpretation der Informationen der hochgenauen Karte werden bekannte Elemente anhand einer Zuordnungsliste kategorisiert. Unbekannte Elemente werden erfasst und anhand einer manuellen Abfrage ebenfalls den Kategorien zugeordnet. Abschließend werden sämtliche Elemente auf ein zweidimensionales Raster übertragen, das in Form einer Pixelmatrix ausgegeben wird.
Getestet wird die implementierte Methode zunächst mit selbst erstellten hochgenauen Karten, die sich an den Anwendungsfällen Automated Valet Parking und Verkehrsberuhigter Bereich orientieren. Im Anschluss erfolgen Tests mit fremd erstellten Karten sowie mit einem exemplarischen graphbasierten Trajektorienplaner. Dabei wird gezeigt, dass die Methode in der Lage ist, aus beliebigen hochgenauen Lanelet2-Karten ein Umgebungsmodell zu generieren, das für die globale Trajektorienplanung der NGF geeignet ist. Eine wesentliche Erkenntnis der Untersuchungen ist, dass die Qualität der hochgenauen Karten maßgeblichen Einfluss auf die Qualität des abgeleiteten Umgebungsmodells besitzt.

description: We consider a random walk with a negative drift and with a jump distribution which under Cramér's change of measure belongs to the domain of attraction of a spectrally positive stable law. If conditioned to reach a high level and suitably scaled, this random walk converges in law to a nondecreasing Markov process which can be interpreted as a spectrally-positive Lévy %-Khinchin process conditioned not to overshoot level one.

description: We compute, for cosmological backgrounds, the $O(d,d;\mathbb{R})$ invariant beta functions for the sigma model of the bosonic string at two loops. This yields an independent first-principle derivation of the order $α'$ corrections to the cosmological target-space equations. To this end we revisit the quantum consistency of Tseytlin's duality invariant formulation of the worldsheet theory. While we confirm the absence of gravitational (and hence Lorentz) anomalies, our results show that the minimal subtraction scheme is not applicable, implying significant technical complications at higher loops. To circumvent these we then change gears and use the Polyakov action for cosmological backgrounds, applying a suitable perturbation scheme that, although not $O(d,d;\mathbb{R})$ invariant, allows one to efficiently determine the $O(d,d;\mathbb{R})$ invariant beta functions.

An analysis of the corpus of scholia and marginalia demonstrates specific manufacturing proclivities for selective groups of texts, while simultaneously revealing a wide variety of possible construction sequences and techniques in others.

description: In order to evaluate qualitatively the space-time evolution of hot and dense nuclear matter the underlying equation of state and transport coefficients must be known. In this study a specific equation of state is studied: the pion gas. The classical or standard transport coefficients, namely the bulk viscosity, shear viscsoity and thermal conductivity are devided by the relaxation times for the corresponding dissipative fluxes and then studied as functions of mass to temperature ratio.

description: Since the seminal paper by Tversky and Kahneman, the conjunction fallacy has been the subject of multiple debates and become a fundamental challenge for cognitive theories in decision-making. In this article, we take a rather uncommon perspective on this phenomenon. Instead of trying to explain the nature or causes of the conjunction fallacy (intensional definition), we analyze its range of factual possibilities (extensional definition). We show that the majority of research on the conjunction fallacy, according to our sample of experiments reviewed which covers literature between 1983 and 2016, has focused on a narrow part of the a priori factual possibilities, implying that explanations of the conjunction fallacy are fundamentally biased by the short scope of possibilities explored. The latter is a rather curious aspect of the research evolution in the conjunction fallacy considering that the very nature of it is motivated by extensional considerations.

description: At the quark level there are basically two types of contributions of R-parity violating SUSY (RPV SUSY) to neutrinoless double beta decay: the short-range contribution involving only heavy virtual superpartners and the long-range one with the virtual squark and neutrino. Hadronization of the effective operators, corresponding to these two types of contributions, may in general involve virtual pions in addition to the close on-mass-shell nucleons. It is known that the short-range contribution is dominated by the pion exchange. In the present paper we show that this is also true for the long-range RPV SUSY contribution and, therefore, the RPV SUSY contributes to the neutrinoless double beta decay dominantly via charged pion exchange between the decaying nucleons.

description: Holevo information is an upper bound for the accessible classical information of an ensemble of quantum states. In this work, we use Holevo information to investigate the ensemble theory interpretation of quantum gravity. We study the Holevo information in random tensor network states, where the random parameters are the random tensors at each vertex. Based on the results in random tensor network models, we propose a conjecture on the holographic bulk formula of the Holevo information in the gravity case. As concrete examples of holographic systems, we compute the Holevo information in the ensemble of thermal states and thermo-field double states in the Sachdev-Ye-Kitaev model. The results are consistent with our conjecture.

description: The ultrafast dynamics of surface electromagnetic waves photogenerated on aluminum film perforated with subwavelength holes array was studied in the visible spectral range by the technique of transient photomodulation with 100 fs time resolution. We observed a pronounced blueshift of the resonant transmission band that reveals the important role of plasma attenuation in the optical response of nanohole arrays. The blueshift is inconsistent with plasmonic mechanism of extraordinary transmission and points to the crucial role of interference in the formation of transmission bands. The transient photomodulation spectra were successfully modeled within the Boltzmann equation approach for the electron-phonon relaxation dynamics, involving non-equilibrium hot electrons and quasi-equilibrium phonons.

description: We present spectroscopic observations of the quiescent black hole binary A0620-00 with the the 6.5-m Magellan Clay telescope at Las Campanas Observatory. We measure absorption-line radial velocities of the secondary and make the most precise determination to date (K2 = 435.4 +/- 0.5 km/s). By fitting the rotational broadening of the secondary, we refine the mass ratio to q = 0.060 +/- 0.004; these results, combined with the orbital period, imply a minimum mass for the compact object of 3.10 +/- 0.04 Msun. Although quiescence implies little accretion activity, we find that the disc contributes 56 +/- 7 per cent of the light in B and V, and is subject to significant flickering. Doppler maps of the Balmer lines reveal bright emission from the gas stream-disc impact point and unusual crescent-shaped features. We also find that the disc centre of symmetry does not coincide with the predicted black hole velocity. By comparison with SPH simulations, we identify this source with an eccentric disc. With high S/N, we pursue modulation tomography of H-alpha and find that the aforementioned bright regions are strongly modulated at the orbital period. We interpret this modulation in the context of disc precession, and discuss cases for the accretion disc evolution.

Optimal Memoryless Encoding for Low Power Off-Chip Data Buses

description: Off-chip buses account for a significant portion of the total system power consumed in embedded systems. Bus encoding schemes have been proposed to minimize power dissipation, but none has been demonstrated to be optimal with respect to any measure. In this paper, we give the first provably optimal and explicit (polynomial-time constructible) families of memoryless codes for minimizing bit transitions in off-chip buses. Our results imply that having access to a clock does not make a memoryless encoding scheme that minimizes bit transitions more powerful.

title: Parawasserstoff Induzierte Hyperpolarisation an Peptiden und Miniproteinen
Creators: name: Lins, Jonas

description: Die Kernspinmagnetresonanzspektroskopie (NMR-Spektroskopie) ist eine bedeutende Technik in der modernen Analytik, vor allem in der Chemie. Darüber hinaus besitzt die NMR eine medizinische Relevanz in Form der Magnetresonanztomographie (MRT). Beide Techniken besitzen allerdings nur eine geringe Sensitivität bedingt durch die niedrigen Energieunterschiede der Kernspinniveaus und der daraus resultierenden geringen Polarisation. Verschiedene Hyperpolarisationstechniken ermöglichen die Verstärkung von NMR-Signalen in der Spektroskopie und der MRT. Die Parawasserstoffinduzierte Polarisation (PHIP) ist eine besonders einfach anwendbare, schnelle und vergleichsweise günstige Methode der Hyperpolarisation. Die Anwendung von PHIP an biologischen Molekülen ermöglicht einfachere und schnellere Untersuchungen von biologischen Prozessen und die Entwicklung neuartiger Kontrastmittel für die Medizin. Während bisher vor allem kleine Moleküle des Stoffwechsels hierfür untersucht wurden, widmet sich diese Arbeit größeren Molekülen wie Peptiden und Miniproteinen. In dieser Arbeit wird PHIP an dem Octapeptid Octreotid und dem Miniprotein MCoTI angewendet. Es wird zunächst die Synthese und der Einbau der speziellen Marker in die Biomoleküle durchgeführt und optimiert. Anschließend wird der Einfluss unterschiedlicher Positionen der Marker in den Biomolekülen auf die Effektivität von PHIP untersucht, diskutiert und ein Bezug zur biologischen Aktivität hergestellt.

description: We report on a first census of Galactic black hole X-ray binary (BHXRB) properties with the second data release (DR2) of {\em Gaia}, focusing on dynamically confirmed and strong candidate black hole transients. DR2 provides five-parameter astrometric solutions including position, parallax and proper motion for 11 of a sample of 24 systems. Distance estimates are tested with parallax inversion as well as Bayesian inference. We derive an empirically motivated characteristic scale length of $L$=2.17$\pm$0.12 kpc for this BHXRB population to infer distances based upon an exponentially decreasing space density prior. Geometric DR2 parallaxes provide new, independent distance estimates, but the faintness of this population in quiescence results in relatively large fractional distance uncertainties. Despite this, DR2 estimates generally agree with literature distances. The most discrepant case is BW Cir, for which detailed studies of the donor star have suggested a distant location at >~25 kpc. A large DR2 measured parallax and relatively high proper motion instead prefer significantly smaller distances, suggesting that the source may instead be amongst the nearest of XRBs. However, both distances create problems for interpretation of the source, and follow-up data are required to resolve its true nature. DR2 also provides a first distance estimate to one source, MAXI J1820+070, and novel proper motion estimates for 7 sources. Peculiar velocities relative to Galactic rotation exceed $\sim$ 50 km s$^{-1}$ for the bulk of the sample, with a median system kinetic energy of peculiar motion of $\sim$ 5 $\times$ 10$^{47}$ erg. BW Cir could be a new high-velocity BHXRB if its astrometry is confirmed. A putative anti-correlation between peculiar velocity and black hole mass is found, as expected in mass-dependent BH kick formation channels, but this trend remains weak in the DR2 data.

Non-Relativistic Superstring Theories

description: We construct a supersymmetric version of the ``critical'' non-relativistic bosonic string theory\cite{Kim:2007hb} with its manifest global symmetry. We introduce the anticommuting $bc$ CFT which is the super partner of the $βγ$ CFT. The conformal weights of the $b$ and $c$ fields are both 1/2. The action of the fermionic sector can be transformed into that of the relativistic superstring theory. We explicitly quantize the theory with manifest SO(8) symmetry and find that the spectrum is similar to that of Type IIB superstring theory. There is one notable difference: the fermions are non-chiral. We further consider ``noncritical'' generalizations of the supersymmetric theory using the superspace formulation. There is an infinite range of possible string theories similar to the supercritical string theories. We comment on the connection between the critical non-relativistic string theory and the lightlike Linear Dilaton theory.
