description: We show here a mesoscopic device based on a narrow ring containing an electron. In the device, an amount of energy is stored in advance. Similar to the pendulum, an exact periodic motion of the electron is thereby initiated afterward. The motion appears as a series of sharp pulses, and is in nature different from the well known Aharonov-Bohm (A-B) oscillation. In particular, the pulses of current can be tuned to be very strong (say, more than two orders stronger than the usual A-B current). Related theory and numerical results are presented.

Toward background error covariance hybridization for climate prediction

Year: 2019

description: The Norwegian Climate Prediction Model (NorCPM) combines the Norwegian Earth System Model (NorESM) with the Ensemble Kalman Filter (EnKF) and aims at providing seasonal to decadal climate predictions. On nowadays supercomputer, it is not computationally tractable to run more than 30 members (and 5 members with the high resolution version of NorCPM), which results in sampling issues when estimating the background error covariance matrix.

To overcome these issues, an hybridization method derived from previous work from (Hamill and Snyder, 2000) has been used and led to the implemeantion of 2 methods: climatological hybridization and dual resolution. These 2 methods allow for a reduction of sampling error when compared to standard EnKF.

The hybrid covariance method are tested with the quasi-geostrophic model within the DAPPER package. It is shown that the method outperforms the standard implementation of the EnKF in particular for small ensemble size.

Further work will assesses the performance of the two methods with NorCPM in the context of twin experiments.

description: We offer an exact analytical equation for the void central region. We show that the central density is solely determined by the amplitude of the initial perturbation. Our results suggest that N-body simulations somewhat overestimate the emptiness of voids: the majority of them should have the central underdensity $δ_c > -73\%$, and there should be almost no voids with $δ_c < -88\%$. The central region of a void is a part of an open Friedmann's 'universe', and its evolution differs drastically from the Universe evolution: there is a long stage when the curvature term dominates, which prevents the formation of galaxy clusters and massive galaxies inside voids. The density profile in the void center should be very flat. We discuss some void models obtained by N-body simulations and offer some ways to improve them. We also show that the dark energy makes the voids less underdense.

We observe new quantum correlations among the pump and signal or idler beams, as well as among the pump and a combined quadrature of signal and idler beams. A further investigation of unforeseen classical noise observed in this system is presented, which hinders the observation of the recently predicted tripartite entanglement. In spite of this noise, current results approach the limit required to demonstrate three-color entanglement.

description: The language of Eutropius' Breviarium shows few traces of Latin  linguistic evolution in late Antiquity: the most important of them refer  to verbal morfosintaxis. The style is characterized by predominance of  coordination and repetition, especially in the first part of the opera,  dedicated to the history of Roman Republic. A lexicological approach  reveals a wide use of the most common military expressions and an  impressive frequency of words concerning with political virtues of Roman  emperors: the word choice indicates the author's personal ideology of  power.

description: We study a hybrid system consisting of a spin-incoherent Luttinger liquid adjoined at one or both ends to a superconductor. We find the tunneling density of states diverges at low energies and exhibits a universal frequency dependence independent of the strength of the interactions in the system. We show that in spite of exponentially decaying pair correlations with distance into the spin-incoherent Luttinger liquid, the Josephson current remains robust. Compared to the zero temperature Luttinger liquid case there is a factor of 2 reduction in the critical current and a halving of the period in the phase difference between the superconductors. Our results open the way for a new class of experiments in the spin-incoherent regime of one dimensional systems.

Deconfinement phase transition in hybrid neutron stars from the Brueckner theory with three-body forces and a quark model with chiral mass scaling

description: We study the properties of strange quark matter in equilibrium with normal nuclear matter. Instead of using the conventional bag model in quark sector, we achieve the confinement by a density-dependent quark mass derived from in-medium chiral condensates. In nuclear matter, we adopt the equation of state from the Brueckner-Bethe-Goldstone approach with three-body forces. It is found that the mixed phase can occur, for a reasonable confinement parameter, near the normal nuclear saturation density, and goes over into pure quark matter at about 5 times the saturation. The onset of mixed and quark phases is compatible with the observed class of low-mass neutron stars, but it hinders the occurrence of kaon condensation.

description: We report the detection of three RR Lyrae (RRL) stars (two RRc and one RRab) in the ultra-faint dwarf (UFD) galaxy Centaurus I (CenI) and two Milky Way (MW) $δ$ Scuti/SX Phoenicis stars based on multi-epoch $giz$ DECam observations. The two RRc stars are located within 2 times the half-light radius (r$_h$) of Cen I, while the RRab star (CenI-V3) is at $\sim6$ r$_h$. The presence of three distant RRL stars clustered this tightly in space represents a 4.7$σ$ excess relative to the smooth distribution of RRL in the Galactic halo. Using the newly detected RRL stars, we obtain a distance modulus to Cen I of $μ_0 = 20.354 \pm 0.002$ mag ($σ=0.03$ mag), a heliocentric distance of D$_\odot = 117.7 \pm 0.1$ kpc ($σ=1.6$ kpc), with systematic errors of $0.07$ mag and $4$ kpc. The location of the Cen I RRL stars in the Bailey diagram is in agreement with other UFD galaxies (mainly Oosterhoff II). Finally, we study the relative rate of RRc+RRd (RRcd) stars ($f_{cd}$) in UFD and classical dwarf galaxies. The full sample of MW dwarf galaxies gives a mean of $f_{cd} = 0.28$. While several UFD galaxies, such as Cen I, present higher RRcd ratios, if we combine the RRL populations of all UFD galaxies, the RRcd ratio is similar to the one obtained for the classical dwarfs ($f_{cd}$ $\sim$ 0.3). Therefore, there is no evidence for a different fraction of RRcd stars in UFD and classical dwarf galaxies.

description: Le Credenze sulla traduzione fanno parte del sistema di credenze sul  linguaggio, sul suo uso e apprendimento. Per uno studente di traduzione  queste credenze sono il punto di partenza, e una vista professionale,  scientificamente fondata, è una << zona di sviluppo prossimale  >> (Vygotskj 2006). Le conoscenze della vita di tutti i giorni e i  concetti scientifici coesistono e interagiscono nella mente degli  individui. La relazione tra le concezioni naïve e quelle  scientifiche è ben altro che un’opposizione: è piuttosto un continuum  tra i due poli, in cui è determinante l’evoluzione storica, sia  personale sia sociale, Gli studenti si trovano in qualche modo “in due  menti” quando sviluppano le capacità e i punti di vista professionali.  Ciò che realmente pensano gli studenti di lingua e di traduzione a volte  è totalmente diverso da quello che gli insegnanti presuppongono.  Nell’articolo viene descritto il discorso ingenuo su lingua e traduzione  derivante dall’osservazione delle opinioni degli insegnanti riguardo  agli errori degli studenti e sulle opinioni degli studenti riguardo ai  propri risultati, e sulla base di interviste e questionari,  auto-narrazioni (interviste scritte), blog e live journal. L’analisi ha rivelato due serie di credenze simili alle credenze generali sul linguaggio e l’apprendimento, legate alla conoscenza o all’azione: teorie o strategie ingenue di traduzione. Le credenze ontologiche (che cos’è la traduzione) sono derivate dalle credenze sul linguaggio. Le credenze tecnologiche (come tradurre)  sono legate alle strategie personali di apprendimento, insegnamento e  uso del linguaggio. La rappresentazione metaforica della traduzione  nella metacognizione ingenua è “sostituzione fisica di unità”, o  traduzione parola per parola, simile alla metafora reificatrice del  linguaggio (“le parole sono come le cose materiali”).

description: IIn 2006 the PVLAS collaboration reported the observation of an optical rotation generated in vacuum by a magnetic field. To further check against possible instrumental artifacts several upgrades to the PVLAS apparatus have been made during the last year. Two data taking runs, at the wavelength of 1064 nm, have been performed in the new configuration with magnetic field strengths of 2.3 T and 5 T. The 2.3 T field value was chosen in order to avoid stray fields. The new observations do not show the presence of a rotation signal down to the levels of $1.2\cdot 10^{-8}$ rad at 5 T and $1.0\cdot 10^{-8}$ rad at 2.3 T (at 95% c.l.) with 45000 passes in the magnetic field zone. In the same conditions no ellipticity signal was detected down to $1.4\cdot 10^{-8}$ at 2.3 T (at 95% c.l.), whereas at 5 T a signal is still present. The physical nature of this ellipticity as due to an effect depending on $B^2$ can be excluded by the measurement at 2.3 T. These new results completely exclude the previously published magnetically induced vacuum dichroism results, indicating that they were instrumental artifacts. These new results therefore also exclude the particle interpretation of the previous PVLAS results as due to a spin zero boson. The background ellipticity at 2.3 T can be used to determine a new limit on the total photon-photon scattering cross section of $σ_{γγ} < 4.5 \cdot10^{-34}$ barn at 95% c.l..

description: Background: Studies on intravoxel incoherent motion (IVIM) imaging are carried out with different acquisition protocols. Purpose: Investigate the dependence of IVIM parameters on the B_0field strength when using a bi- or triexponential model. Field Strength/Sequence: 20 volunteers were examined at two field strengths (1.5 and 3T). Diffusion-weighted images of the abdomen were acquired at 24 b-values ranging from 0.2 to 500 s/mm2. Assessment: ROIs were manually drawn in the liver. Data were fitted with a bi- and a triexponential IVIM model. Resulting parameters were compared between both field strengths. Results: At b-values below 6s/mm2, the triexponential model provided better agreement with the data than the biexponential model. The average tissue diffusivity was D=1.22/1.00 um/ms at 1.5/3T. The average pseudo-diffusion coefficients for the biexponential model were D*=308/260um/ms at 1.5/3T; and for the triexponential model D1*=81.3/65.9um/ms , D2*=2453/2333um/ms at 1.5/3T. The average perfusion fractions for the biexponential model were f=0.286/0.303 at 1.5/3T; and for the triexponential model f1=0.161/0.174 and f2=0.152/0.159 at 1.5/3T. A significant B0 dependence was only found for the biexponential pseudo-diffusion coefficient (ANOVA/KW p=0.037/0.0453) and tissue diffusivity (ANOVA/KW: p<0.001). Conclusion: Our experimental results suggest that triexponential pseudo-diffusion coefficients and perfusion fractions obtained at different field strengths could be compared across different studies using different B0. However, it is recommendable to take the field strength into account when comparing tissue diffusivities or using the biexponential IVIM model. Considering published values for oxygenation-dependent transversal relaxation times of blood, it is unlikely that the two blood compartments of the triexponential model represent venous and arterial blood.

description: (abridged) The ESIS survey is the optical follow up of the SWIRE/Spitzer in the ELAIS-S1 region of the sky. In the era of observational cosmology, the main efforts are focused on the study of galaxy evolution and its environmental dependence. Wide area, multiwavelength, extragalactic surveys are needed in order to probe sufficiently large volumes, minimize cosmic variance and find significant numbers of rare objects. We present VIMOS I and z band imaging belonging to the ESIS survey. A total of ~4 deg2 were targeted in I and ~1 deg2 in z. More than 300000 galaxies have been detected in the I band and ~50000 in the z band. Object coordinates are defined within an uncertainty of ~0.2 arcsec r.m.s., with respect to GSC 2.2. We reach a 90% average completeness at 23.1 and 22.5 mag (Vega) in the I and z bands, respectively. On the basis of IRAC colors, we identified galaxies having the 1.6 um stellar peak shifted to z=1-3. The new I, z band data provide reliable constraints to avoid low-redshift interlopers and reinforce this selection. Roughly 1000 galaxies between z=2-3 were identified over the ESIS ~4 deg2, at the SWIRE 5.8 um depth (25.8 uJy at 3sigma). These are the best galaxy candidates to dominate the massive tail (M>1e11 Msun) of the z>2 mass function.

description: We perform a systematic study of dihedral groups used as flavor symmetry. The key feature here is the fact that we do not allow the dihedral groups to be broken in an arbitrary way, but in all cases some (non-trivial) subgroup has to be preserved. In this way we arrive at only five possible (Dirac) mass matrix structures which can arise, if we require that the matrix has to have a non-vanishing determinant and that at least two of the three generations of left-handed (conjugate) fermions are placed into an irreducible two-dimensional representation of the flavor group. We show that there is no difference between the mass matrix structures for single- and double-valued dihedral groups. Furthermore, we comment on possible forms of Majorana mass matrices. As a first application we find a way to express the Cabibbo angle, i.e. the CKM matrix element |V_{us}|, in terms of group theory quantities only, the group index n, the representation index j and the index m_{u,d} of the different preserved subgroups in the up and down quark sector: |V_{us}|=|cos(pi(m_{u}-m_{d})j/n)| which is |cos(3 pi/7)| = 0.2225 for n=7, j=1, m_{u}=3 and m_{d}=0. We prove that two successful models which lead to maximal atmospheric mixing and vanishing theta_{13} in the lepton sector are based on the fact that the flavor symmetry is broken in the charged lepton, Dirac neutrino and Majorana neutrino sector down to different preserved subgroups whose mismatch results in the prediction of these mixing angles. This also demonstrates the power of preserved subgroups in connection with the prediction of mixing angles in the quark as well as in the lepton sector.

The preliminary design of an aquaculture facility using systems analysis techniques : a British Columbia case study
Creators: name: MacKinlay, Don D.
Publisher: name: University of British Columbia
Year: 2010

description: A method is presented for the selection of a conceptual design of an aquaculture facility using a systems approach whereby many alternatives for each facility component are generated and evaluated before selection and detailed design are carried out. Included are extensive literature reviews of design and operation of aquaculture facilities and mathematical modeling methodology for analysing the production of aquatic organisms. The method is applied to the design of a facility to fit into an existing cattle ranch in the dry interior of British Columbia near Nicola Lake. The two operations (agriculture and aquaculture) are seen as mutually beneficial: the ranch can provide husbandry and technical manpower, shared machinery and equipment and loan collateral to the fish farm; and the fish farm can provide income diversification and waste nutrient rich water for irrigation to the ranch. The chosen design was that of an intensive culture trout farm using gravity fed surface water from Moore Creek feeding into above ground plastic raceways (10,000 trout per raceway). The raceways are arranged down the natural slope of the land with serial recycling of the water, biological filtration after every third reuse and re-aeration before entering each raceway. Gross economic analysis indicates that although some trout farm sizes would not be profitable, a very small operation (one or two raceways) would pay for itself and a moderately large operation (six to ten raceways) would produce a good return on investment. Mathematical models for fish, invertebrate and algal growth and fish respiration were adapted to the design process by incorporating them into interactive computer programs in the BASIC language for the APPLE microcomputer. Calculation procedures for the design of solar and conventional heating and biological filtration of the process water, pipeline design selection, and capital and operations costing were developed as formatted matrices on a commercial spreadsheet program so that many options could be evaluated with ease. A tabular evaluation format was developed to quantitatively rank the suitability of various potential alternative design configurations for each component of the overall system to aid in alternative select ion. The steps required to turn this conceptual design into a working pilot plant leading to a viable production facility are outlined, along with the areas of greatest uncertainty in the design.

description: Particle accelerators that use electromagnetic fields to increase a charged particle's energy have greatly advanced the development of science and industry since invention. However, the enormous cost and size of conventional radio-frequency accelerators have limited their accessibility. Here we demonstrate a mini-accelerator powered by terahertz pulses with wavelengths 100 times shorter than radio-frequency pulses. By injecting a short relativistic electron bunch to a 30-mm-long dielectric-lined waveguide and tuning the frequency of a 20-period terahertz pulse to the phase-velocity-matched value, precise and sustained acceleration for nearly 100% of the electrons is achieved with the beam energy spread essentially unchanged. Furthermore, by accurately controlling the phase of two terahertz pulses, the beam is stably accelerated successively in two dielectric waveguides with close to 100% charge coupling efficiency. Our results demonstrate stable and scalable beam acceleration in a multistage mini-accelerator and pave the way for functioning terahertz-driven high-energy accelerators.

description: The Daya Bay reactor neutrino experiment, which pioneered the measurement of a non-zero value for the neutrino mixing angle $θ_{13}$ in 2012, operated for nearly nine years, from Nov.~24, 2011, to Dec.~12, 2020. Antineutrinos produced by six reactors, each with a thermal power of 2.9 GW, were detected by eight identically designed detectors located in two near and one far underground experimental halls. The experimental setup, featuring kilometer-scale baselines between the detectors and reactors, enabled precise investigations within the three-neutrino mixing framework. This proceeding presents the latest measurements of the neutrino mixing angle $θ_{13}$ and the mass-squared difference $Δm_{32}^2$, based on samples tagged via gadolinium capture ($n$Gd) and hydrogen capture ($n$H). The combined results from Daya Bay's most recent $n$Gd and $n$H data sets provide a $2.6\%$ precision for $\sin^22θ_{13}$. Additionally, a search for light sterile neutrinos with full data set is summarized.
Non-universal dynamics of dimer growing interfaces

description: A finite temperature version of body-centered solid-on-solid growth models involving attachment and detachment of dimers is discussed in 1+1 dimensions. The dynamic exponent of the growing interface is studied numerically via the spectrum gap of the underlying evolution operator. The finite size scaling of the latter is found to be affected by a standard surface tension term on which the growth rates depend. This non-universal aspect is also corroborated by the growth behavior observed in large scale simulations. By contrast, the roughening exponent remains robust over wide temperature ranges.

description: The identification of cosmic objects emitting high energy neutrinos could provide new insights about the Universe and its active sources. The existence of these cosmic neutrinos has been proven by the IceCube collaboration, but the big question of which sources these neutrinos originate from, remains unanswered. The KM3NeT detector for Astroparticle Research with Cosmics in the Abyss (ARCA), with a cubic kilometer instrumented volume, is currently being built in the Mediterranean Sea. It will excel at identifying cosmic neutrino sources due to its unprecedented angular resolution for muon neutrinos (< 0.2 degree for E > 10 TeV events). KM3NeT has a view of the sky complementary to IceCube, and is sensitive to neutrinos across a wide range of energies. In order to identify the signature of cosmic neutrino sources in the background of atmospheric neutrinos and muons, statistical methods are being developed and tested with Monte-Carlo pseudo experiments. This contribution presents the most recent sensitivity estimates for diffuse, point-like and extended neutrino sources with KM3NeT/ARCA.

A practical solution for linear inference computations
Creators: name: Schlax, Michael Garfield
Publisher: name: University of British Columbia
Year: 2010

description: In this thesis, I shall present a matrix form of Backus' theory of linear inference with multiple predictions. The Bayesian approach of Backus allows the treatment of erroneous data and the imposition of the essential a priori bound on the model norm. The X² statistic will be introduced to construct a most likely model and bound the norm of all acceptable models from above and below. This results in more reliable, and possibly more confining, estimates of the predictions than provided by only an upper bound. The algorithm derived is robust and efficient, and estimates comparable to those obtained from Oldenburg's linear programming algorithm have been achieved.

description: Earth-like planets in the habitable zone of low-mass stars undergo strong tidal effects that modify their spin states. These planets are expected to host dense atmospheres that can also play an important role in the spin evolution. On one hand, gravitational tides tend to synchronise the rotation with the orbital mean motion, but on the other hand, thermal atmospheric tides push the rotation away and may lead to asynchronous equilibria. Here, we investigate the complete tidal evolution of Earth-like planets by taking into account the effect of obliquity and eccentric orbits. We adopted an Andrade rheology for the gravitational tides and benchmarked the unknown parameters with the present rotation of Venus. We then applied our model to Earth-like planets, and we show that asynchronous rotation can be expected for planets orbiting stars with masses between 0.4 and 0.9 $M_\odot$ and semi-major axes between 0.2 and 0.7 au. Interestingly, we find that Earth-like planets in the habitable zone of stars with masses $\sim 0.8$ $M_\odot$ may end up with an equilibrium rotation of 24 hours. We additionally find that these planets can also develop high obliquities, which may help sustain temperate environments.

description: CONTEXT:The footpoints of quiet Sun Transition Region (TR) loops do not seem to coincide with the photospheric magnetic structures appearing in traditional low-sensitivity magnetograms. AIMS: To look for the so-far unidentified photospheric footpoints of TR loops using G-band bright points (BPs) as proxies for photospheric magnetic field concentrations. METHODS: Comparison of TR measurements with SoHO/SUMER and photospheric magnetic field observations obtained with the Dutch Open Telescope. RESULTS: Photospheric BPs are associated with bright TR structures, but they seem to avoid the brightest parts of the structure. BPs appear in regions that are globally redshifted, but they avoid extreme velocities. TR explosive events are not clearly associated with BPs. CONCLUSIONS: The observations are not inconsistent with the BPs being footpoints of TR loops, although we have not succeeded to uniquely identify particular BPs with specific TR loops.

Spectral compression by phase doubling in second harmonic generation

description: In second harmonic generation, the phase of the optical field is doubled which has important implication. Here the phase doubling effect is utilized to solve a long-standing challenge in power scaling of single frequency laser. When a (-π/2, π/2) binary phase modulation is applied to a single frequency seed laser to broaden the spectrum and suppress the stimulated Brillouin scattering in high power fiber amplifier, the second harmonic of the phase-modulated laser will return to single frequency, because the (-π/2, π/2) modulation is doubled to (-π, π) for the second harmonic. A compression rate as high as 95% is demonstrated in the experiment limited by the electronic bandwidth of the setup, which can be improved with optimized devices.

Seasonal rhythm. From April to May, end of the dry season.
*Part A and part B indicated for D. sutori.
Nycthemeral rhythm. Irregular activity from about 8.10 a.m. to 6.30 p.m.
Calling site and calling posture. Called on the trunks or on under sides of principal stems of various trees. During sound production, males raised their abdomen and lifted up their wings upon their body without any decoapitation with the mesonotum (thorax).
Calling song. Began with a soft, low and long buzzing (part A) lasting up to 50 s, and ended with an intensive sound phrase lasting about 20 s (part B) with amplitude modulations. Part A was sometimes lacking (see Behaviour). Part A was made up of groups of four distinct pulses with a repetition rate of 45 Hz. Part B consisted of a continuous train of pulses. Pulses were of similar length and produced with a frequency at about 200 Hz. Pulses of part B consisted of coherent oscillations at the dominant frequency band of about 2000 Hz.
Behaviour. Groups of three to five individuals staying at their calling site formed choruses. They were spaced with a 2–4 m minimal distance but may have occupied distinct trees. One male initiated the chorus. When this ‘leader’ male was producing part B of the call, surrounding males produced in reaction the same part B at the same time but not synchronously. So, surrounding males did not emit part A of the calling song. The ‘leader’ male was not always the same. Activity of one chorus centre stimulated the sound production of nearby groups. These intragroup and intergroup relationships led to the production of intensive choruses when the density of the species was high.

Chiral corrections to the scalar form factor in B_q to D_q transitions

description: We consider chiral loop corrections to the scalar form factor in B_q to D_q l nu decays. First we consider chiral corrections to the 1/m_Q suppressed operators and then we propose the procedure for the extraction of the relevant form factor using lattice QCD results. In the case of B_s to D_s l nu decay we find that effects of kinematics and chiral corrections tend to cancel for the scalar form factor contributions. In particular the 1/m_Q suppression of chiral corrections is compensated by the SU(3) flavor symmetry breaking corrections which can be as large as 30%. The calculated corrections are relevant for the precise determination of possible new physics effects in B_q to D_q l nu decays.

The cytogenetic consequences of spontaneous cell fusion in Zea mays L.
Creators: name: Peeters, John P.
Publisher: name: University of British Columbia
Year: 2010

description: The origin of spontaneously occurring new karyotypes containing additional DNA has remained enigmatic, although these genomic changes have been frequently reported in the literature both in vivo and in vitro. This study describes the cytogenetic consequences of spontaneous cell fusion in vivo during meiosis in the pollen mother cells of Zea mays L. It suggests that spontaneous cell fusion is a natural mechanism which can contribute not only to the formation of spontaneously occurring polyploids but also to aneuploidy and to the genesis of new karyotypes which contain additional structurally modified chromosomes, or B chromosomes.

description: We report on our analysis of 300 ks of Chandra observations of the neutron star soft X-ray transient 1H1905+000 in quiescence. We do not detect the source down to a 95% confidence unabsorbed flux upper limit of 2E-16 erg cm-2 s-1 in the 0.5-10 keV energy range for an assumed Gamma=2 power law spectral model. A limit of 1.4E-16 erg cm-2 s-1 is derived if we assume that the spectrum of 1H1905+000 in quiescence is described well with a black body of temperature of 0.2 keV. For the upper limit to the source distance of 10 kpc this yields a 0.5-10 keV luminosity limit of 2.4E30 / 1.7E30 erg/s for the abovementioned power law or black body spectrum, respectively. This luminosity limit is lower than the luminosity of A0620-00, the weakest black hole soft X-ray transient in quiescence reported so far. Together with the uncertainties in relating the mass transfer and mass accretion rates we come to the conclusion that the claim that there is evidence for the presence of a black hole event horizon on the basis of a lower quiescent luminosity for black holes than for neutron stars is unproven. We also briefly discuss the implications of the low quiescent luminosity of 1H1905+000 for the neutron star equation of state. Using deep Magellan images of the field of 1H1905+000 obtained at excellent observing conditions we do not detect the quiescent counterpart at the position of the outburst optical counterpart down to a magnitude limit of i'>25.3. This can be converted to a limit on the absolute magnitude of the counterpart of I>9.6 which implies that the counterpart can only be a brown or a white dwarf.

description: An artin algebra $A$ is said to be CM-finite if there are only finitely many, up to isomorphisms, indecomposable finitely generated Gorenstein-projective $A$-modules. We prove that for a Gorenstein artin algebra, it is CM-finite if and only if every its Gorenstein-projective module is a direct sum of finitely generated Gorenstein-projective modules. This is an analogue of Auslander's theorem on algebras of finite representation type (\cite{A,A1}).
