description: We construct local, unitary gauge theories that violate Lorentz symmetry explicitly at high energies and are renormalizable by weighted power counting. They contain higher space derivatives, which improve the behavior of propagators at large momenta, but no higher time derivatives. We show that the regularity of the gauge-field propagator privileges a particular spacetime breaking, the one into into space and time. We then concentrate on the simplest class of models, study four dimensional examples and discuss a number of issues that arise in our approach, such as the low-energy recovery of Lorentz invariance.

 Aplidium antillense: Monniot, 1972: 953; 1983: 414.
 Material examined: collected in 2004, at 31°23.815' N, 80°53.461' W, specimen #172 (KBPIG 1/1236) and at 31°36.056' N, 80°47.431' W, specimen #190 (KBPIG 2/1237); 2006, specimen #36 (KBPIG 3/1378) and specimen #38 (KBPIG 4/1379) both collected at 31°36.056' N, 80°47.431' W.
 Previous records: Martinique (Gravier, 1955), Guadeloupe (Monniot, 1983) and Bermudas (Monniot, 1972).
 Description. Colony is a small low cushion with irregular margins (KBPIG 1/1236, Fig. 1 A) or a flat sheet up to 40x 35 mm in extent and 8–9 mm thick (KBPIG 2/1237, Fig. 1 B). Zooids are arranged in double rows separated by oval or irregular zooid-free spaces that are slightly elevated. The limits of each system and a common cloacal opening are not discernible. Fine sand grains are spread over the surface and present throughout the colony, but only occasionally abundant. Otherwise the test is colourless and transparent. Living specimens are described by collectors as having an "almost transparent tunic with visible orange zooids inside".
Most zooids are strongly contracted and have short posterior abdomens. Less contracted zooids are rarer and up to 7.5 mm in length, half of which consists of the posterior abdomen. A simple atrial languet arises from the upper rim of the small atrial opening. The branchial sac has either 12 (KBPIG 1/1236) or 11 or 12 (KBPIG 2/1237) rows of stigmata. A cylindrical stomach, located in the middle of the abdomen, has 12–14 high, strait unbroken folds. The ovary, containing one or two large ova, is in the middle of the posterior abdomen. The testis follicles are serially arranged in two rows just posterior to the ovary. The sperm duct is very thick in all zooids and sometimes fills almost the entire width of the anterior part of the posterior abdomen.
Up to five serially arranged embryos are in the atrial cavity of almost all zooids examined. The trunk of the tailed larva is 0.75 mm in length. Three or occasionally four adhesive organs alternate with wide, short median ampullae (which are sometimes absent) and bunches of epidermal vesicles branching off of them. A single arc of vesicles is on each side of the adhesive organs.
 Remarks. The present specimens conform to those described by Monniot (1972, 1983). The larva illustrated by Monniot (1972, Fig.2 D) appears to be immature and groups of epidermal vesicles between the adhesive organs are not shown.

description: Higher-order topological insulators host gapless states on hinges or corners of three-dimensional crystals. Recent studies suggested that even topologically trivial insulators may exhibit fractionally quantized charges localized at hinges or corners. Although most of the previous studies focused on two-dimensional systems, in this work, we take the initial step toward the systematic understanding of hinge and corner charges in three-dimensional insulators. We consider five crystal shapes of vertex-transitive polyhedra with the cubic symmetry such as a cube, an octahedron and a cuboctahedron. We derive real-space formulas for the hinge and corner charges in terms of the electric charges associated with bulk Wyckoff positions. We find that both the hinge and corner charges can be predicted from the bulk perspective only modulo certain fractions depending on the crystal shape, because the relaxation near boundaries of the crystal may affect the fractional parts. In particular, we show that a fractionally quantized charge $1/24$ mod $1/12$ in the unit of elementary charge can appear in a crystal with a shape of a truncated cube or a truncated octahedron. We also investigate momentum-space formulas for the hinge and corner charges. It turns out that the irreducible representations of filled bands at high-symmetry momenta are not sufficient to determine the corner charge. We introduce an additional Wilson-loop invariant to resolve this issue.

description: We numerically model the coronal mass ejection (CME) event of October 28, 2003 that erupted from active region 10486 and propagated to Earth in less than 20 hours causing severe geomagnetic storms. The magnetohydrodynamic (MHD) model is formulated by first arriving at a steady state corona and solar wind employing synoptic magnetograms. We initiate two CMEs from the same active region, one approximately a day earlier that preconditions the solar wind for the much faster CME on the 28th. This second CME travels through the corona at a rate of over 2500 km s$^{-1}$ driving a strong forward shock. We clearly identify this shock in an image produced by the Large Angle Spectrometric Coronagraph (LASCO) C3, and reproduce the shock and its appearance in synthetic white light images from the simulation. We find excellent agreement with both the general morphology and the quantitative brightness of the model CME with LASCO observations. These results demonstrate that the CME shape is largely determined by its interaction with the ambient solar wind and may not be sensitive to the initiation process. We then show how the CME would appear as observed by wide-angle coronagraphs onboard the Solar Terrestrial Relations Observatory (STEREO) spacecraft. We find complex time evolution of the white-light images as a result of the way in which the density structures pass through the Thomson sphere. The simulation is performed with the Space Weather Modeling Framework (SWMF).

description: In the present paper, we study the robustness of two-dimensional random lattices (Delaunay triangulations) under attacks based on betweenness centrality. Together with the standard definition of this centrality measure, we employ a range-limited approximation known as $\ell$-betweenness, where paths having more than $\ell$ steps are ignored. For finite $\ell$, the attacks produce continuous percolation transitions that belong to the universality class of random percolation. On the other hand, the attack under the full range betweenness induces a discontinuous transition that, in the thermodynamic limit, occurs after removing a sub-extensive amount of nodes. This behavior is recovered for $\ell$-betweenness if the cutoff is allowed to scale with the linear length of the network faster than $\ell\sim L^{0.91}$. Our results suggest that betweenness centrality encodes information on network robustness at all scales, and thus cannot be approximated using finite-ranged calculations without losing attack efficiency.

description: Fragt man Wissenschaftler, was ihnen von zurückliegenden Forschungsaufenthalten an anderen Einrichtungen am deutlichsten in Erinnerung geblieben sei, so lautet die Antwort häufig: "Die Kantine und die Bibliothek". Auch wenn mit zunehmender Digitalisierung immer mehr Informationen an jedem Ort zu jeder Zeit zur Verfügung stehen, spielt der "Raum Bibliothek" in einem modernen Forschungszentrum nach wie vor eine wichtige Rolle. Gleichzeitig ändern sich die Anforderungen an wissenschaftliche Spezialbibliotheken:Durch Open Access (OA) und Open Science kommt es bereits jetzt zu grundlegenden Transformationen im Publikationswesen. Im Zusammenhang mit Raubverlagen, Scheinkonferenzen und bei Urheberrechtsfragen wird großer Unterstützungsbedarf in den Forschungszentren  deutlich. Bibliotheken, die sich diesen Anforderungen stellen, neue Kompetenzen aktiv erwerben und beispielsweise aktiv in den Publikationsprozess eingebunden sind, tragen dazu bei, dass die hohe Qualität der Forschungsergebnisse sichtbar und die Konkurrenzfähigkeit das Zentrum erhalten bleiben.Am Beispiel des Deutschen Elektronen-Synchrotron DESY, dessen Forschungsschwerpunkt sich in den letzten Jahren deutlich verschoben hat, wird deutlich wie sich die Anforderungen an die über fünfzig Jahre alte Bibliothek im Laufe der Jahre geändert haben und welche Maßnahmen letztlich erfolgreich waren, damit die Bibliothek auf dem Weg zu einer "Informationsdrehscheibe" unverändert ein geachtetes Aushängeschild und Kompetenzzentrum ist.

description: Aerosols under chaotic advection often approach a strange attractor. They move chaotically on this fractal set but, in the presence of gravity, they have a net vertical motion downwards. In practical situations, observational data may be available only at a given level, for example at the ground level. We uncover two fractal signatures of chaotic advection of aerosols under the action of gravity. Each one enables the computation of the fractal dimension $D_{0}$ of the strange attractor governing the advection dynamics from data obtained solely at a given level. We illustrate our theoretical findings with a numerical experiment and discuss their possible relevance to meteorology.

description: The growth of spiral mounds containing a screw dislocation is compared to the growth of wedding cakes by two-dimensional nucleation. Using phase field simulations and homoepitaxial growth experiments on the Pt(111) surface we show that both structures attain the same characteristic large scale shape when a significant step edge barrier suppresses interlayer transport. The higher vertical growth rate observed for the spiral mounds on Pt(111) reflects the different incorporation mechanisms for atoms in the top region and can be formally represented by an enhanced apparent step edge barrier.

description: The COVID-19 pandemic is the most significant global crisis since World War II that affected almost all the countries of our planet. To control the COVID-19 pandemic outbreak, it is necessary to understand how the virus is transmitted to a susceptible individual and eventually spread in the community. The primary transmission pathway of COVID-19 is human-to-human transmission through infectious droplets. However, a recent study by Greenhalgh et al. (Lancet: 397:1603-1605, 2021) demonstrates 10 scientific reasons behind the airborne transmission of SARS-COV-2. In the present study, we introduce a novel mathematical model of COVID-19 that considers the transmission of free viruses in the air besides the transmission of direct contact with an infected person. The basic reproduction number of the epidemic model is calculated using the next-generation operator method and observed that it depends on both the transmission rate of direct contact and free virus contact. The local and global stability of disease-free equilibrium (DFE) is well established. Analytically it is found that there is a forward bifurcation between the DFE and an endemic equilibrium using central manifold theory. Next, we used the nonlinear least-squares technique to identify the best-fitted parameter values in the model from the observed COVID-19 mortality data of two major districts of India. Using estimated parameters for Bangalore urban and Chennai, different control scenarios for mitigation of the disease are investigated. Results indicate that when a vaccine crisis is there, the public health authorities should prefer to vaccinate the susceptible people compared to the recovered persons who are now healthy. Along with face mask use, treatment of hospitalized patients and vaccination of susceptibles, immigration should be allowed in a supervised manner so that economy of the overall society remains healthy.

description: We compute the perturbative short-time expansion for the transition amplitude of a particle in curved space time, by employing Dimensional Regularization (DR) to treat the divergences which occur in some Feynman diagrams. The present work generalizes known results where DR was applied to the computation of one-loop effective actions, which in the worldline approach are linked to particle path integrals on the circle, i.e. with periodic boundary conditions. The main motivation of the present work comes from revived interest in particle transition amplitudes in curved space-times, due to their use in the recently proposed worldline quantum field theory (in curved space-time).

description: We study the impurity suppression of the critical temperature $T_c$ of the FeAs superconductors theoretically based on the the $\pm$s-wave pairing state of a two band model. The effects of non-magnetic and magnetic impurities are studied with the $\mathcal{T}$-matrix approximation, which can continuously treat impurity scattering from weak to strong coupling limit. We found that both magnetic and non-magnetic impurities suppress $T_c$ with a rate that is practically indistinguishable from the standard d-wave case despite a possibly large difference of the positive and negative s-wave order parameter (OP) magnitudes. This is because the density of states enters together with the OP magnitude for the scattering process.

description: We have studied hetero- and homonuclear excited state/ground state collisions by loading both $^{85}$Rb and $^{87}$Rb into a far off resonant trap (FORT). Because of the relatively weak confinement of the FORT, we expect the hyperfine structure of the different isotopes to play a crucial role in the collision rates. This dependence on hyperfine structure allows us to measure collisions associated with long range interatomic potentials of different structure: such as long and short ranged; or such as purely attractive, purely repulsive, or mixed attractive and repulsive. We observe significantly different loss rates for different excited state potentials. Additionally, we observe that some collisional channels' loss rates are saturated at our operating intensities (~15 mW/cm$^{2}$). These losses are important limitations in loading dual isotope optical traps.

description: Coherent control of complex many-body systems is critical to the development of useful quantum devices. Fast perfect state transfer can be exactly achieved through additional counterdiabatic fields. We show that the additional energetic overhead associated with implementing counterdiabatic driving can be reduced while still maintaining high target state fidelities. This is achieved by implementing control fields only during the impulse regime, as identified by the Kibble-Zurek mechanism. We demonstrate that this strategy successfully suppresses most of the defects that would be generated due to the finite driving time for two paradigmatic settings: the Landau-Zener model and the Ising model. For the latter case, we also investigate the performance of our impulse control scheme when restricted to more experimentally realistic local control fields.

description: Dyslexia is a learning disability in the area of reading. It is included in the category of -learning Disabilities- in the Individuals with Disabilities Education Act (IDEA). The present study has assessed the acquired reading disabilities which are related to the oral representation of language. To achieve the aim of the research, an eight-year-old boy, who suffered from dyslexia, has been investigated and his disabilities have been evaluated. During the process of research, the boy has received some treatments and this conclusion has drawn that treating dyslexia can help a child to improve his other skills of language acquisition. Owing to the fact that dyslexia treatment can help a child in many ways, especially second language acquisition, the findings of this research can be helpful for non-Persian language learners who are acquiring Persian language and teach them how to augment their language skills.

description: In the lacunar spinel GaV4S8, the interplay of spin, charge, and orbital degrees of freedom produces a rich phase diagram that includes an unusual Neel-type skyrmion phase composed of molecular spins. To provide insight into the interactions underlying this complex phase diagram, we study the spin excitations in GaV4S8 through inelastic neutron scattering measurements on polycrystalline and single-crystal samples. Using linear spin-wave theory, we describe the spin-wave excitations using a model where V4 clusters decorate an FCC lattice. The effective cluster model includes a ferromagnetic interaction and a weaker antisymmetric Dzyaloshinskii-Moriya (DM) interaction between the neighboring molecular spins. Our work clarifies the spin interactions in GaV4S8 and supports the picture of interacting molecular clusters.

 Description. The one colony examined is in rather poor condition. The colony is a small, irregular thin sheet encrusting a colony of bryozoa. The peripheral layer of the test is filled with minute granules and by large amounts of sand which are present in the internal test. The zooids are strongly contracted and up to 4 mm long, but usually shorter. A simple, small atrial languet arises from the upper margin of the slit-like atrial opening. The branchial sac has 9 rows of stigmata, but the number of stigmata per row is obscured. The abdomen is the same size as the thorax. The stomach is asymmetrical and has five, deep longitudinal folds. The posterior abdomen is about half as long as the zooid and zooids examined contain no gonads.
 Remarks. This specimen might be identical to A. lobatum: Van Name, 1945 although the latter specimens may have fewer rows of stigmata ("about seven" according to Van Name 1945: 29). The specimens from Guadeloupe have nine rows of stigmata (Monniot and Monniot, 1984). It is difficult to determine if all of the mentioned specimens belong to the same species, although they are probably not related to A. lobatum Savigny, 1816 originally described from the Red Sea (for discussion see Kott, 1992: 512–513).

description: Let f(x) be a continuous function from a compact real interval into itself with a periodic orbit of minimal period m, where m is not an integral power of 2. Then, by Sharkovsky's theorem, for every positive integer n with m \prec n in the Sharkovsky's ordering defined below, a lower bound on the number of periodic orbits of f(x) with minimal period n is 1. Could we improve this lower bound from 1 to some larger number? In this paper, we give a complete answer to this question.

Remarks
Our material coincides in both morphology and measurements with those given for S. patagonica by Galea et al. (2017), who synonymized Sertularella striata Stechow, 1923 with S. patagonica after a literature review. It also fits well with the colonies described by Gili et al. (1989, as S. striata) from the Namibian coast, but this record was considered as doubtful by Galea et al. (2017) due to the hydrothecal measurements being larger than those reported for S. patagonica in the literature. However, there are some contradictions between the measurements given by Gili et al. (1989) in the text and those that we have obtained from their figure 29a; indeed, the latter fall within the size range given for S. patagonica, and Namibian colonies prove identical with those collected at Vema Seamount. Consequently, we consider our Namibian material as conspecific with S. patagonica.
Distribution
In the Atlantic, Sertularella patagonica was recorded from the Argentinean coast (Galea et al. 2017) and off Namibia (Gili et al. 1989, as S. striata), and from the east coast of South Africa, Mozambique (Millard 1975) and India (Nagale & Apte 2014, as S. striata) in the Indian Ocean. Its bathymetric distribution ranges from the intertidal (Nagale & Apte 2014, as S. striata) to 429 m (Gili et al. 1989, as S. striata).

description: The detection of cytomegalovirus (CMV) in the setting of inflammatory bowel disease often creates confusion whether CMV is a ‘bystander’ or ‘disease.’ This review discusses the clinical conundrum of CMV in ulcerative colitis, approach to discriminate infection from disease, and therapeutic considerations (immunosuppressive and anti-CMV treatment). CMV disease should be considered in corticosteroid refractory- dependent and thiopurine refractory disease. Endoscopy may reveal deep punched out ulcers, irregular ulcers, or cobble-stoning. The diagnosis rests on the presence and abundance of viral inclusion bodies on hematoxylin and eosin stain, positive immunohistochemistry, and/or positive tissue polymerase chain reaction. CMV disease is associated with worse outcomes including increased colectomy rates. The timing and duration of antiviral drugs in CMV disease is debatable but depends on the load of CMV in tissue. In high-grade infection, CMV needs to be treated while increasing immunosuppression may work in the setting of low-grade infection. Ganciclovir is the drug of choice for treatment of CMV disease. Tumor necrosis factor inhibitors may be useful for treating underlying disease activity in the setting of CMV. Other emerging therapies include fecal microbiota transplantation. Randomized studies are necessary to define the best timing and duration of anti-CMV therapy.
Search for X-ray bursts in the INTEGRAL/IBIS data of 2003-2005 and discovery of the new X-ray burster IGR J17364-2711/17380-3749

description: All the observations performed with the IBIS telescope aboard the INTEGRAL observatory during the first 2.5 years of its in-orbit operation have been analyzed to find X-ray bursts. There were 1788 statistically confident events with a duration from 5 to 500 s revealed in time records of the 15-25 keV count rate of the IBIS/ISGRI detector, 319 of them were localized and, with one exception, identified with persistent X-ray sources. The known bursters were responsible for 215 of the localized events. One burst was detected from AXJ1754.2-2754, the source previously unknown as a burster, and another burst - from a new source. There was duality in determining its position - its name could be either IGR J17364-2711 or IGR J17380-3749. Curiously enough, the 138 bursts were detected from one X-ray burster - GX 354-0.

On the quadratic variation of semi-martingales
Creators: name: Lemieux, Marc
Publisher: name: University of British Columbia
Year: 2010

description: Let X be a semi-martingale. Techniques of [1] and El Karoui (in [3] and [4]) are used to study the convergence of 2∊ times the number of upcrossings of [x, x+∊] by X to its local time at x. If X is continuous and if there exists a bicontinuous version of its local time process, then off a single null set, the convergence is shown to be uniform in x (and time). If X is such that the sum of the absolute value of its jumps over any finite time interval is almost surely finite, then, off a single null set, the convergence holds at all but countably many x. A notion of generalized arc length, is introduced, in the spirit of the quadratic arc length of [1], and the last result above is used to show that  is the almost sure arc length of X, a uniform limit recoverable from the geometry of the trajectories.
Weighted power counting and Lorentz violating gauge theories. II: Classification

description: We classify the local, polynomial, unitary gauge theories that violate Lorentz symmetry explicitly at high energies and are renormalizable by weighted power counting. We study the structure of such theories and prove that renormalization does not generate higher time derivatives. We work out the conditions to renormalize vertices that are usually non-renormalizable, such as the two scalar-two fermion interactions and the four fermion interactions. A number of four dimensional examples are presented.

The history and doctrines of the Karrāmiyya sect with special reference to ar-Rāzī's criticism
Creators: name: El-Galli, Aḥmad Muḥammad Aḥmad
Publisher: name: The University of Edinburgh
Year: 1970
Subjects: theology

description: The objective of this thesis is the study of the history and doctrines of one of the Muslim sects namely the Karramiyya sect, with special attention made to Fakhr ad-Dln ar-RazI's criticism of the sect's doctrines and views. Therefore the first chapter of this study is dedicated to the study of ar-Razi's life in particular that part connected with his involvement with the Karramites. In the second chapter I have treated the history of the sect starting from its founder Muhammad Ibn-Karram including various aspects of his life as well as his achievement and significance. It is also dealt here with the history of the sect after Ibn-Karram and the role which his adherents had played in the life of Khurasan and the Ghur regime. The following chapters have been devoted to the explanation of the theological doctrines of the sect. In the third chapter it is dealt with the Karramite views regarding the nature of God and the problems related to their views in this respect. Therefore a section of this chapter is concerned with the sect's views of the Essence of God, another with their views of God's attributes and the third with their theory of the origination and annihilation of the world. The sect's views regarding the problem of Free will and predestination have been considered in the fourth chapter, and in the fifth their Doctrine of faith and its further implications have been treated. And in the last chapter the Karramite concept of the Prophecy have been considered. All this has been dealt with in comparison between the Karramites views and the views of other sects, particularly the Asb'arites whose views were presented mainly by Fakhr ad-Din ar-RazI.

description: In recent years, our view of the Magellanic Clouds has shifted due to a rapidly expanding pool of data. Hubble Space Telescope-measured proper motions (PMs) of the Clouds revealed their first infall and the timescale on which they most recently interacted. With the advent of Gaia however, a new avenue of exploration has opened into the history of the Clouds. Here we present measurements of the PMs in Magellanic stars from Gaia across the Magellanic Bridge compared against simulations of different interaction histories of the Clouds, revealing a strong preference for a recent and direct last interaction. We additionally present an analysis of the internal dynamics of the Small Magellanic Cloud (SMC). In particular, we show our search for rotation within the stellar populations of the SMC, hinted at by HI studies and stellar radial velocity measurements. In combination with simulations of interactions between the Clouds, we attempt to improve our physical understanding and intuition for the complex dynamic scenario that is the Magellanic Clouds.

description: We propose a method, which enables precise control of magnetic patterns, relying only on the fundamental properties of the wire and the choice of the path in the controlled parameter space but not on the rate of motion along this path. Possible experimental realizations of this mechanism are discussed. In particular, we show that the domain walls in magnetic nanowires can be translated by rotation of the magnetic easy axis, or by applying pulses of magnetic field directed transverse to the magnetic easy axis.

description: For resectable esophageal cancer (EC), it remains controversial whether to place percutaneous endoscopic gastrostomy (PEG) before the curative surgery to provide nutritional support during the neoadjuvant therapy. To compare surgical outcomes for patients who received preoperative PEG and those without PEG placement (No-PEG) insertion prior to surgery in a potentially operable EC. A comprehensive literature search was conducted to identify randomized and non-randomized studies comparing PEG and No-PEG groups. Four retrospective studies with a total number of 1,027 patients were identified and included in this meta-analysis. The differences in anastomotic leakage, anastomotic stricture, morbidity, pulmonary complications, wound infection, and hospital stay were not statistically significant between the two groups. Operation time was significantly shorter in the PEG group. There was no PEG-related gastric conduit failure and no leak from the PEG site in the PEG group. We conclude preoperative PEG for resectable EC is a safe procedure with no adverse effect on the gastric tube construction and anastomosis, it can be selectively inserted for EC patients with marked weight loss and malnutrition or those at risk of developing malnutrition during neoadjuvant therapy.

description: Biliary diversion (BD) is indicated in progressive familial intrahepatic cholestasis (PFIC) with refractory pruritus. Three types-partial external biliary drainage (PEBD), partial internal biliary drainage (PIBD), and ileal exclusion (IE) are described, with no consensus about the relative efficacy of these procedures. PubMed, Scopus, and Google Scholar were searched for publications on PFIC and BD. Improvement in pruritus, serum bile acid (BA), and need for liver transplantation (LT) were compared between the various BD procedures 25 studies [424 children (PEBD–301, PIBD–93, IE–30)] were included. Pruritus resolved in 59.5% [PIBD:72% (95%CI 43–96%), PEBD:57% (95%CI 43–71%) and IE:48% (95%CI 14–82%)] cases. Significant overlap in confidence intervals indicated no significant differences. Absolute decrease in BA (AUROC–0.72) and bilirubin (AUROC–0.69) discriminated responders and non-responders. Eventually, 27% required LT: PIBD 10.7%, PEBD32%, IE 27%. The post-operative BA (AUROC-0.9) and bilirubin (AUROC-0.85) determined need for LT. Complications were commoner in PEBD than PIBD (38% vs 21.8%: p=0.02). 59.5% children have pruritus relief after BD and 27% need LT. PIBD has lower complications and LT requirement than PEBD. However, this requires cautious interpretation as the 2 groups differed in PFIC type and follow-up duration.

description: We study the Standard-Model extensions that have the following features: they violate Lorentz invariance explicitly at high energies; they are unitary, local, polynomial and renormalizable by weighted power counting; they contain the vertex (LH)^2, which gives Majorana masses to the neutrinos after symmetry breaking, and possibly four fermion interactions; they do not contain right-handed neutrinos, nor other extra fields. We study the simplest CPT invariant Standard-Model extension of this type in detail and prove the cancellation of gauge anomalies. We investigate the low-energy recovery of Lorentz invariance and comment on other types of extensions.
