description: The hyperelliptic mapping class group has been studied in various contexts within topology and algebraic geometry. What makes this study tractable is that there is a surjective map from the hyperelliptic mapping class group to a mapping class group of a punctured sphere. The more general family of superelliptic mapping class groups does not, in general, surject on to a mapping class group of a punctured sphere, but on to a finite index subgroup. We call this finite index subgroup the liftable mapping class group. In order to initiate the generalization of results on the hyperelliptic mapping class group to the broader family of superelliptic mapping class groups, we study an intermediate family called the balanced superelliptic mapping class group. We compute the index of the liftable mapping class group in the full mapping class group of the sphere and show that the liftable mapping class group is independent of the degree of the cover. We also build a presentation for the liftable mapping class group, compute its abelianization, and show that the balanced superelliptic mapping class group has finite abelianization. Although our calculations focus on the subfamily of balanced superelliptic mapping class groups, our techniques can be extended to any superelliptic mapping class group, even those not within the balanced family.

We also provide existence results and explicit constructions for surfaces of type I,..., VII, recovering all classical examples and discovering several new ones. In particular, triple planes of type VII provide counterexamples to a wrong claim made in 1942 by Bronowski.

description: We consider the free boundary problem arising from an energy functional which is the sum of a Dirichlet energy and a nonlinear function of either the classical or the fractional perimeter. The main difference with the existing literature is that the total energy is here a nonlinear superposition of the either local or nonlocal surface tension effect with the elastic energy. In sharp contrast with the linear case, the problem considered in this paper is unstable, namely a minimizer in a given domain is not necessarily a minimizer in a smaller domain. We provide an explicit example for this instability. We also give a free boundary condition, which emphasizes the role played by the domain in the geometry of the free boundary. In addition, we provide density estimates for the free boundary and regularity results for the minimal solution. As far as we know, this is the first case in which a nonlinear function of the perimeter is studied in this type of problems. Also, the results obtained in this nonlinear setting are new even in the case of the local perimeter, and indeed the instability feature is not a consequence of the possibly nonlocality of the problem, but it is due to the nonlinear character of the energy functional.

Ziel unserer Untersuchungen war es herauszufinden, ob diese Peptide in der Lage sind, auch nach Kurzzeitinkubation eine suffiziente Inhibition der Adhäsion bzw. eine Ablösung adhärenter Zellen und damit eine ausreichende Prävention des Nachstars zu bewirken. Außerdem wurde überprüft, ob das von uns verwendete RGD-Peptid eine Toxizität für die Hornhaut aufweist. Material und Methoden: Kulturen boviner und humaner LEC, boviner Hornhautendothelzellen, humane und bovine Linsenkapselexzidate und humane explantierte Hornhäute wurden verwendet. Wir untersuchten die Inhibition der Adhäsion und die Ablösung konfluenter LEC-Layer mittels des zyklischen RGD-Peptids cRGDDFV (Inkubationszeiten von 1 Stunde bzw. 5-7 Tagen und Konzentrationen von 10-4 M, 10-3 M und 2x10-3 M wurden angewandt). Ergebnisse: Wir fanden nach nur einstündiger Inkubation in der Kulturschale eine Adhäsionsinhibition von 48% für bovine LEC und von 100% für humane LEC.

description: Purpose: RGD-peptides competitively inihibit adhesion molecules of the lens epithelial cells (LEC). The purpose of our study was to investigate whether this peptide could be able to inhibit adhesion sufficiently after short term incubation resp. to detach adherent cells and so to prevent posterior capsule opacification (PCO). Also there was proofed if there is any toxicity for the cornea. Methods: Cultures of bovine and human LEC, bovine cornea endothelial cells, humane and bovine fragments of the lens capsule and explanted humane corneas were used. The inhibition of adhesion and the detachment of confluent LEC-layer by the cyclic RGD-peptide cRGDDFV were studied (incubation time was 1 hour resp. 5-7 days and concentrations of 10-4, 10-3 M and 2x10-3 M were used). Results: After one hour incubation time in a culture dish inhibition of adhesion was 48% for bovine LEC resp. 100% for humane LEC. There was a statistically significant difference between the control-peptide-group and cRGDDFV (p

description: The Eulerian perfect-fluid theory is reformulated from its action principle in a pure field-theoretic manner. Conservation of the convective current is no longer imposed by Lin's constraints, but rather adopted as the central idea of the theory. Our formulation, for the first time, successfully reduces redundant degrees of freedom promoting one half of the Clebsch variables as the true dynamical fields. Interactions on these fields allow for the exchange of the convective current of quantities such as mass and charge, which are uniformly understood as the breaking of the underlying symmetry of the force-free fluid. The Clebsch fields play the essential role in the exchange of angular momentum with the force field producing vorticity.

description: Perturbation theory of thermodynamic potentials in QCD at $T>T_c$ is considered with the nonperturbative background vacuum taken into account. It is shown that the magnetic confinement in the QCD vacuum prevents the infrared catastrophe of the perturbation theory present in the case of the free vacuum (the "Linde problem"). A short discussion is given of the applicability of the nonperturbative formalism at large $T$ and of the relation with the HTL theory.The observation of A.D.Linde, that the terms $O(g^n), n>6$ contribute to the order $O(g^6)$ is confirmed also with the account of the colormagnetic confinement, and it is shown that the latter makes these terms IR convergent, and summable. As a result one obtains the selfconsistent theory of the gluon plasma.

Data-driven priors and their posterior concentration rates

description: In high-dimensional problems, choosing a prior distribution such that the corresponding posterior has desirable practical and theoretical properties can be challenging. This begs the question: can the data be used to help choose a good prior? In this paper, we develop a general strategy for constructing a data-driven or empirical prior and sufficient conditions for the corresponding posterior distribution to achieve a certain concentration rate. The idea is that the prior should put sufficient mass on parameter values for which the likelihood is large. An interesting byproduct of this data-driven centering is that the asymptotic properties of the posterior are less sensitive to the prior shape which, in turn, allows users to work with priors of computationally convenient forms while maintaining the desired rates. General results on both adaptive and non-adaptive rates based on empirical priors are presented, along with illustrations in density estimation, nonparametric regression, and high-dimensional structured normal models.

description: Al finalizar la confección del compilado de crónicas urbanas, podemos concluir que hay un movimiento rockero en la ciudad, a pesar de toda la dificultad que supone crear música y vivencias bajo fuertes condiciones sociales que oprimen y señalan lo diferente. Esta dura condición, sirve como nutriente para aquellos que se dedican a la creación musical, produciendo sonidos autóctonos que bien podrían llevar el rótulo de rock cartagenero. Para encontrar lo anterior, se hizo necesario hallar una línea de referentes que permitieran leer las experiencias de vida de los sujetos participantes, para otorgarles un punto de llegada, un sentido para sus gustos. Los conceptos que permitieron lo anterior son: prácticas musicales, identidad social, interpelación y lecturas, todo contemplado desde el universo conceptual de los estudios culturales. La elaboración de lascrónicas, necesitó además, un paquete de referencias que ordenen su proceso de creación y redacción. Para esto, los logros de la comunicadora Adriana Montes, entregan los parámetros conceptuales, metodológicos y prácticos que definen un apropiado ejercicio periodístico. Para ella, “la crónica es un género transdicursivo que usa el testimonio, entre otros discursos, como parte de una estrategia narrativa global a partir de la que define en buena medida su carácter político y contestatario.” A través de todo lo anterior, se obtuvo una visión estructurada y teorizada de lo que es la práctica cultual rockera en Cartagena, que se mantiene activa a través de las numerosas bandas de rock, de sus seguidores, en distintos establecimientos comerciales que usan el rock como tema y, por qué no, en los constantes críticos que hablan y opinan.

description: Collision sequences are commonly used in games and entertainment to add drama and excitement. Authoring even two body collisions in the real world can be difficult, as one has to get timing and the object trajectories to be correctly synchronized. After tedious trial-and-error iterations, when objects can actually be made to collide, then they are difficult to capture in 3D. In contrast, synthetically generating plausible collisions is difficult as it requires adjusting different collision parameters (e.g., object mass ratio, coefficient of restitution, etc.) and appropriate initial parameters. We present SMASH to directly read off appropriate collision parameters directly from raw input video recordings. Technically we enable this by utilizing laws of rigid body collision to regularize the problem of lifting 2D trajectories to a physically valid 3D reconstruction of the collision. The reconstructed sequences can then be modified and combined to easily author novel and plausible collisions. We evaluate our system on a range of synthetic scenes and demonstrate the effectiveness of our method by accurately reconstructing several complex real world collision events.

description: The generalization error of deep neural networks via their classification margin is studied in this work. Our approach is based on the Jacobian matrix of a deep neural network and can be applied to networks with arbitrary non-linearities and pooling layers, and to networks with different architectures such as feed forward networks and residual networks. Our analysis leads to the conclusion that a bounded spectral norm of the network's Jacobian matrix in the neighbourhood of the training samples is crucial for a deep neural network of arbitrary depth and width to generalize well. This is a significant improvement over the current bounds in the literature, which imply that the generalization error grows with either the width or the depth of the network. Moreover, it shows that the recently proposed batch normalization and weight normalization re-parametrizations enjoy good generalization properties, and leads to a novel network regularizer based on the network's Jacobian matrix. The analysis is supported with experimental results on the MNIST, CIFAR-10, LaRED and ImageNet datasets.

description: Host galaxy properties provide strong constraints on the stellar progenitors of superluminous supernovae. By comparing a sample of 19 low-redshift (z < 0.3) superluminous supernova hosts to galaxy populations in the local Universe, we show that sub-solar metallicities seem to be a requirement. All superluminous supernovae in hosts with high measured gas-phase metallicities are found to explode at large galactocentric radii, indicating that the metallicity at the explosion site is likely lower than the integrated host value. We found that superluminous supernovae hosts do not always have star-formation rates higher than typical star-forming galaxies of the same mass. However, we confirm that high absolute specific star-formation rates are a feature of superluminous supernova host galaxies, but interpret this as simply a consequence of the anti-correlation between gas-phase metallicity and specific star-formation rate and the requirement of on-going star formation to produce young, massive stars greater than ~ 10-20 M_sol. Based on our sample, we propose an upper limit of ~ 0.5 Z_sol for forming superluminous supernova progenitors (assuming an N2 metallicity diagnostic and a solar oxygen abundance of 8.69). Finally, we show that if magnetar powering is the source of the extreme luminosity then the required initial spins appear to be correlated with metallicity of the host galaxy. This correlation needs further work, but if it holds it is a powerful link between the supernova parameters and nature of the progenitor population.

description: The Gibbs canonical state, as a maximum entropy density matrix, represents a quantum system in equilibrium with a thermostat. This state plays an essential role in thermodynamics and serves as the initial condition for nonequilibrium dynamical simulations. We solve a long standing problem for computing the Gibbs state Wigner function with nearly machine accuracy by solving the Bloch equation directly in the phase space. Furthermore, the algorithms are provided yielding high quality Wigner distributions for pure stationary states as well as for Thomas-Fermi and Bose-Einstein distributions. The developed numerical methods furnish a long-sought efficient computation framework for nonequilibrium quantum simulations directly in the Wigner representation.

description: We study the transient dynamics of a viscous liquid contained in a narrow gap between a rigid surface and a parallel elastic plate. The elastic plate is deformed due to an externally applied time-varying pressure-field. We model the flow-field via the lubrication approximation, and the plate deformation by the Kirchhoff-Love plate theory. We obtain a self-similarity solution for the case of an external point force acting on the elastic plate. The pressure and deformation field during and after the application of the external force are derived and presented by closed form expressions. We examine a uniform external pressure acting on the elastic plate over a finite region and during a finite time period, similar to the viscous-elastic interaction time-scale. The interaction between elasticity and viscosity is shown to reduce by order of magnitude the pressure within the Hele-Shaw cell compared with the externally applied pressure, thus suggesting such configurations may be used for impact mitigation.

For an $e^+e^-$ collider running at $500$ GeV center-of-mass energy and $100$ fb$^{-1}$ of integrated luminosity the simultaneous limits on the anomalous couplings are $1\sim3\times 10^{-3}$.

description: Meson states with exotic quantum numbers arise naturally in a covariant bound-state framework in QCD. We investigate the consequences of shifting quark masses such that the states are no longer restricted to certain C-parities, but only by J^P. Then, a priori, one can no longer distinguish exotic or conventional states. In order to identify signatures of the different states to look for experimentally, we provide the behavior of masses, leptonic decay constants, and orbital-angular-momentum decomposition of such mesons, as well as the constellations in which they could be found. Most prominently, we consider the case of charged quasi-exotic excitations of the pion.

description: Recent research has demonstrated that there is considerable inter-individual variation in the response to aerobic training, and that this variation is partially mediated by genetic factors. As such, we aimed to investigate if a genetic based algorithm successfully predicted the magnitude of improvements following eight-weeks of aerobic training in youth soccer players. A genetic test was utilised to examine five single nucleotide polymorphisms (VEGF rs2010963, ADRB2 rs1042713 and rs1042714, CRP rs1205 & PPARGC1A rs8192678), whose occurrence is believed to impact aerobic training adaptations. 42 male soccer players (17.0 ± 1y, 176 ± 6 cm, 69 ± 9 kg) were tested and stratified into three different Total Genotype Score groups; “low”, “medium”and “high”, based on the possession of favourable polymorphisms. Subjects underwent two Yo-Yo tests separated by eight-weeks of sports-specific aerobic training. Overall, there were no significant differences between the genotype groups in pre-training Yo-Yo performance, but evident between-group response differentials emerged in post-training Yo-Yo test performance. Subjects in the “high” group saw much larger improvements (58%) than those in the ‘medium” (35%) and “low” (7%) groups. There were significant (p<0.05) differences between the groups in the magnitude of improvement, with athletes in the “high” and medium group having larger improvements than the “low” group (d = 2.59 “high” vs “low”; d = 1.32 “medium” vs “low”). In conclusion, the magnitude of improvements in aerobic fitness following a training intervention were associated with a genetic algorithm comprised of five single nucleotide polymorphisms. This information could lead to the development of more individualised aerobic training designs, targeting optimal fitness adaptations.

description: We study the diphoton excesses near $750$ GeV recently reported by the ATLAS and CMS collaborations within the context of a phenomenologically interesting intersecting/magnetized D-brane model on a toroidal orientifold. It is shown that the model contains a SM singlet scalar as well as vector-like quarks and leptons. In addition, it is shown that the singlet scalar has Yukawa couplings with vector-like quarks and leptons such that it may be produced in proton-proton collisions via gluon fusion as well as decay to diphotons through loops involving the vector-like quarks. Moreover, the required vector-like quarks and leptons may appear in complete $SU(5)$ multiplets so that gauge coupling unification may be maintained. Finally, it is shown that the diphoton signal may be explained within the model.

description: Control of autonomous mobile robots in dynamical environments is interesting from a cognitive point of view as well as under application view points. Stimulus response controls are often favored for fast reactions to the environment. On the other hand, goals and plans are needed to guide long term behaviour by deliberative control. Layered architectures are used for combination, but they inherit advantages as well as problems from both approaches. The paper prosposes the Double Pass Architecture with hierarchically structures options/behaviours providing fast reactions on all levels.

Including the individual enhancements of $χ_3$ and $χ_4$ near a critical point, these features may be a consistent set of observations supporting the interpretation of baryon fluctuations data as arising from criticality.

description: We present a bidirectional modification of the standard one-qubit teleportation protocol, where both Alice and Bob transfer noisy versions of their qubit states to each other by using single Bell state and auxiliary (trigger) qubits. Three schemes are considered: the first where the actions of parties are governed by two independent quantum random triggers, the second with single random trigger, and the third as a mixture of the first two. We calculate the fidelities of teleportation for all schemes and find a condition on correlation between trigger qubits in the mixed scheme which allows us to overcome the classical fidelity boundary of 2/3. We apply the Choi-Jamiolkowski isomorphism to the quantum channels obtained in order to investigate an interplay between their ability to transfer the information, entanglement-breaking property, and auxiliary classical communication needed to form correlations between trigger qubits. The suggested scheme for bidirectional teleportation can be realized by using current experimental tools.

description: Aim: Cholinergic regulation is important in the control of cardiovascular and endocrine responses. The mechanisms behind cardiovascular responses induced by cholinergic activation are explored by studying hormonal systems, including renin-angiotensin and vasopressin (VP). Results: In chronically prepared fetal sheep, intravenous infusion of the cholinergic agonist carbachol increased fetal systolic, diastolic, and mean arterial pressure accompanied with bradycardia at near-term. Although intravenous administration of carbachol had no effect on plasma VP concentrations, this agonist increased angiotensin I and angiotensin II levels in fetal plasma. Fetal blood values, including sodium, osmolality, nitric oxide, hemoglobin, and hematocrit were unchanged by intravenous carbachol. Conclusion: Cholinergic activation by carbachol controls fetal blood pressure and heart rate in utero. An over-activated fetal renin-angiotensin-system (RAS) is associated with changes in vascular pressure following intravenous administration of carbachol, indicating that the cholinergic stimulation-mediated hormonal mechanism in the fetus might play a critical role in the regulation of cardiovascular homeostasis.

description: We study certain classes of local sets of the two-dimensional Gaussian free field (GFF) in a simply-connected domain, and their relation to the conformal loop ensemble CLE(4) and its variants. More specifically, we consider bounded-type thin local sets (BTLS), where thin means that the local set is small in size, and bounded-type means that the harmonic function describing the mean value of the field away from the local set is bounded by some deterministic constant. We show that a local set is a BTLS if and only if it is contained in some nested version of the CLE(4) carpet, and prove that all BTLS are necessarily connected to the boundary of the domain. We also construct all possible BTLS for which the corresponding harmonic function takes only two prescribed values and show that all these sets (and this includes the case of CLE(4)) are in fact measurable functions of the GFF.

description: We analyse the trapping of eigenspinors of the charge conjugation operator with dual helicity (Elko), in thin and thick string-like models with codimension-2. Elko spinor fields describe mass dimension one fermions in four dimensions (and, correspondingly, mass dimension two fermions in six dimensions), that represent natural dark matter prime candidates. This dark spinor has many applications, from particle physics to cosmology. On the other hand, six-dimensional brane-world models have, among other prominent features, the spontaneous confinement of free spin 1 fields and a mechanism that explains the mass hierarchy of fundamental fermions. In this paper, we use scalar couplings in order to confine the zero mode of Elko in six dimensions. Moreover, we use the Elko dark spinor features to propose an exotic coupling in order to remove the complex-valued terms in the massive Kaluza-Klein modes. Hence, we show that six dimensional models can resolve the main issues of Elko fields confinement presented in five dimensions.

description: According to the Auslander's formula one way of studying an abelian category ${\mathcal{C}}$ is to study ${\rm mod}\mbox{-}{\mathcal{C}}$, that has nicer homological properties than ${\mathcal{C}}$, and then translate the results back to ${\mathcal{C}}$. Recently Krause gave a derived version of this formula and thus renewed the subject. This paper contains a detailed study of various versions of Auslander formula including the versions for all modules and for unbounded derived categories. We apply them to include some results concerning recollements of triangulated categories.

description: Die vorliegende Arbeit verallgemeinert die Methode der Wellenpaketpropagation fuer isolierte molekulare Systeme auf molekulare Systeme mit Umgebungswechselwirkung. Im Rahmen der Dichtematrixtheorie werden am Beispiel des linearen Absorptionskoeffizienten und des Raman-Streuquerschnitts Ausdruecke fuer stationaere optische Funktionen abgeleitet. Diese Ausdruecke lassen sich als Fouriertransformation einer durch Dichtematrixpropagation erhaltenen Groesse verstehen, deren Dynamik auch durch die Umgebung des molekularen Systems beeinflusst wird. Am Beispiel von drei Modellsystemen (OH-Streckschwingung von Wasser, NO in Ar-Matrizen, HCl in Ar-Matrizen) wird der lineare Absorptionskoeffizient im infraroten und ultravioletten Spektralbereich berechnet. Die Ergebnisse werden mit experimentellen Daten verglichen. Aus der numerisch ansruchsvollen drei-dimensionalen Behandlung des HCl in Ar werden zusaetzlich Schluesse ueber die Dynamik des H-Atoms bei der Photodissoziation gezogen. Der Ausdruck fuer den Raman-Streuquerschnitt wird an einem theoretischen Modellsystem untersucht. Insbesondere wird die Temperatur- und Feldstaerkeabhaengigkeit des Spektrums diskutiert.
description: The well-known wave paket propagation method is extended from isolated molecular systems to molekular systems interacting with a dissipative environment. In the framework of density matrix theory formulations of stationary optical properties (linear absorption and Raman scattering cross section) are found. Essentially these formulations contain the Fourier-transform of a term given by density matrix propagation which is influenced by the environment. For three examples (OH stretching vibration in liquid water, NO in Ar-matrices, HCl in Ar-matrices) the linear absorption coefficient is calculated in the infrared and ultraviolett spectral range. Comparisons with experimental data are given. For the case of HCl in Ar-matrices additional information concerning the dynamics of the H-atom during the photodissociation is given. The Raman scattering cross section is calculated for a theoretical model system. Especially temperature dependence and the influence of the electric field strength on the spectra is discussed.

description: Material und Methode: In einer retrospektiven Analyse wurden die Daten von 53 konsekutiven Patienten, 31 Männer und 22 Frauen, mit klinisch oder röntgenologisch präsenten metastatischen epiduralen Spinalkanalkompression ausgewertet. Das mediane Alter war 60 Jahre. Als Primärtumor waren Bronchialkarzinome (13 Patienten), Mammakarzinome (10) und Prostatakarzinome (10) am häufigsten zu finden. Ergebnisse: Die Therapieergebnisse hinsichtlich der Schmerzlinderung waren mit der Literatur vergleichbar (Ansprechrate= 66%). Als wichtigster prognostischer Faktor hinsichtlich der Gehfähigkeit hat sich der prätherapeutische Status erwiesen. Patienten, die Anfang der Therapie gehfähig waren, blieben in 94% der Fälle auch gehfähig, während nur ein Patient seine Gehfähigkeit bis Ende der Therapie wiedergewann (p< 0,001). Im Chi-Quadrat Test war auch der diagnosestellende Arzt prognostisch relevant: Patienten, deren Diagnose durch einen onkologisch tätigen Arzt gestellt wurde, hatten eine höhere Chance gehfähig zu bleiben (p=0,04). Das Gesamtüberleben (8 Monate median, Range 1-27 Monate ) entsprach den Literaturangaben. Nicht ambulante Patienten und Patienten mit Bronchialkarzinom hatten eine signifikant schlechtere Prognose (p
description: Materials and Methods: therapy charts of 53 consecutive patients, 31 male and 22 female, with metastatic epidural spinal cord compression treated with radiation therapy only have been analyzed. Median age was 60 ys. The most frequent primary tumours were bronchogenic carcinoma (13 patients), breast cancer (10 patients) and prostate cancer (10 patients),respectively.Results: MRI was the most sensitive diagnostic tool in detecting spinal cord compression. Plain X-ray films were not useful.Pain symptoms improved in 66% of the patients. The most important prognostic factor was the pretreatment mobility status. 94% of the ambulatory patients kept their walking ability but only one plegic patient could walk again after radiation therapy. (p=0.001) Patients whose back pain was presented to an oncologist were more likely to keep walking ability by the end of the therapy. (p=0.04) Patients with bronchogenic cancer and plegic patients had a significant worse survival. Conclusion: Patients with a known malignant tumor and progressive or axial back pain should undergo MRI scan to rule out spinal cord compression. For patients without severe neuorologic deficit and MRI proven epidural compression radiation therapy is able to preserve walking ability and reduce pain. General practitioners and patients should be informed about the symptoms and the therapeutic and diagnostic possibilities of spinal cord dompression.

description: Jinping Neutrino Experiment (Jinping) is proposed to significantly improve measurements on solar neutrinos and geoneutrinos in China Jinping Laboratory - a lab with a number of unparalleled features, thickest overburden, lowest reactor neutrino background, etc., which identify it as the world-best low-energy neutrino laboratory. The proposed experiment will have target mass of 4 kilotons of liquid scintillator or water-based liquid scintillator, with a fiducial mass of 2 kilotons for neutrino-electron scattering events and 3 kilotons for inverse-beta interaction events. A number of initial sensitivities studies have been carried out, including on the transition phase for the solar neutrinos oscillation from the vacuum to the matter effect, the discovery of solar neutrinos from the carbon-nitrogen-oxygen (CNO) cycle, the resolution of the high and low metallicity hypotheses, and the unambiguous separation on U and Th cascade decays from the dominant crustal anti-electron neutrinos in China.

description: Papillomatous digital dermatitis (PDD or Footwarts) is prevalent on California dairies. The prevalence on some dairies exceeds 50%. An effective and long-lasting treatment for digital dermatitis is needed to minimize the need for repeated treatments. The objective of our treatment trials was to test the efficacy of antimicrobics (Oxytetracycline and Lincomycin/Spectinomycin) at 2 concentrations and 1 astringent (RotNot ™) on footwart lesions in dairy cows over a 90 day observation period.
