Cold dark matter cosmology conflicts with fluid mechanics and observations
Creators: name: Gibson, Carl H.
Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Cold dark matter hierarchical clustering (CDMHC) cosmology based on the Jeans 1902 criterion for gravitational instability gives predictions about the early universe contrary to fluid mechanics and observations. Jeans neglected viscosity, diffusivity, and turbulence: factors that determine gravitational structure formation and contradict small structures (CDM halos) forming from non-baryonic dark matter particle candidates. From hydro-gravitational-dynamics (HGD) cosmology, viscous-gravitational fragmentation produced supercluster (10^46 kg), cluster, and galaxy-mass (10^42 kg) clouds in the primordial plasma with the large fossil density turbulence (rho_o ~ 3x10-17 kg m-3) of the first fragmentation at 10^12 s, and a protogalaxy linear and spiral clump morphology reflecting maximum stretching near vortex lines of the plasma turbulence at the 10^13 s plasma-gas transition. Gas protogalaxies fragmented into proto-globular-star-cluster mass (10^36 kg) clumps of protoplanet gas clouds that are now frozen as earth-mass (10^24-^25 kg) Jovian planets of the baryonic dark matter, about 30,000,000 rogue planets per star. Observations contradict the CDMHCC prediction of large explosive Population III first stars at 10^16 s, but support the immediate gentle formation of small Population II first stars at 10^13 s in globular-star-clusters from HGD.

description: The bispectrum is a 3-point statistic with the potential to provide additional information beyond power spectra analyses of survey datasets. Radio telescopes which broadly survey the 21cm emission from neutral hydrogen (HI) are a promising way to probe LSS and in this work we present an investigation into the HI intensity mapping (IM) bispectrum using simulations. We present a model of the redshift space HI IM bispectrum including observational effects from the radio telescope beam and 21cm foreground contamination. We validate our modelling prescriptions with measurements from robust IM simulations, inclusive of these observational effects. Our foreground simulations include polarisation leakage, on which we use a Principal Component Analysis cleaning method. We also investigate the effects from a non-Gaussian beam including side-lobes. For a MeerKAT-like single-dish IM survey at $z=0.39$, we find that foreground removal causes a 8% reduction in the equilateral bispectrum's signal-to-noise ratio $S/N$, whereas the beam reduces it by 62%. We find our models perform well, generally providing $χ^2_\text{dof}\sim 1$, indicating a good fit to the data. Whilst our focus is on post-reionisation, single-dish IM, our modelling of observational effects, especially foreground removal, can also be relevant to interferometers and reionisation studies.
description: 19 pages, 14 figures. The main results for telescope beam and foreground effects on the bispectrum can be found in Sec 3.2 and 3.3.

Επιπλέον, παρουσιάστηκε η ευκαιρία για εκτενή αναφορά σε σημαντικές προσωπικότητες της περιόδου καθώς και σε ζητήματα που ταλάνιζαν την μεσοπολεμική Ευρώπη, όπως σύγκρουση ιδεολογιών και ζητήματα μειονοτήτων.
description: The primary aim of the present thesis was the factual presentation of the two-year period 1938-1939, “through the eyes” of the British and French diplomats, at the most important capital cities of Europe and the role that they played in the interwar developments. They are presented bilaterally -in every case a British and a French ambassador- with the purpose to indicate contradistinctively the british and french diplomacy during that specific period, while always putting in the spotlight the personal influence of the diplomats in all the matters that were raised. Additionally, the possibility was given to present the criticism that they were subjected to and also the relationships that they built with their political leadership and the leadership of the country of accreditation. Moreover, there was a chance for a thorough reference at some important personalities of the period and also at matters that tormented the interwar Europe, like ideological conflicts or minority problems.

RECONSTRUCTION OF A DOWNTOWN: THE AFTERMATH OF THE GREAT BALTIMORE FIRE OF 1904
Creators: name: Wingo, Amanda Jean
Publisher: name: Digital Repository at the University of Maryland
Year: 1993

description: Reconstruction following a major disaster has farreaching
impacts which can alter the functioning of a
city. Understanding this process is therefore vital.
The results of such a study add to the small body of
literature on reconstruction following disaster and thus
provides additional testing of the findings of
Bowden(l967), the critical piece of literature on
reconstruction to date.
Specifically, this thesis considers the process of
reconstruction by looking at the structural and spatial
changes predicted by one catastrophic event. Using both
Sanborn Atlases and Baltimore Business Directories
between 1902 and 1914, the Central Business District
(CBD) is examined through the analysis of concentration,
sequencing, and persistence processes. More important,
however, is the extent to which these processes impact
the spatial characteristics of establishments within the
Burnt District over a specific period of time (1902-
--- ·--·--
1914).
A significant finding indicates that in the pre- and
post-fire period Baltimore maintains a high degree of
consistency within the Burnt District. However 1 the
vertical dimension of Baltimore changes drastically from
1902 to 1914 allowing an increase in the availability of
space explained by the vertical growth of buildings. The
sequence of return of the "building block" establishments
occurred within a surprising two years following the
fire. Several defining situations fix or anchor
establishments to their locations 1 which act to mitigate
the variations in land-use patterns over time.
The findings of this study provide a spatial view of
the functional districts which play an important role in
the life of the CBD of Baltimore.

description: Magnetic strings are defined as infinitely thin surfaces which are closed in the vacuum and can be open on an external monopole trajectory (that is, defined by 't Hooft loop). We review briefly lattice data on the magnetic strings which refer mostly to SU(2) and SU(3) pure Yang-Mills theories and concentrate on implications of the strings for the Yang-Mills plasma. We argue that magnetic strings might be a liquid component of the Yang-Mills plasma and suggest tests of this hypothesis.

description: In an atomic Bose-Einstein condensate quenched to the unitary regime, we predict the sequential formation of a significant fraction of condensed pairs and triples. At short-distances, we demonstrate the two-body and Efimovian character of the condensed pairs and triples, respectively. As the system evolves, the size of the condensed pairs and triples becomes comparable to the interparticle distance, such that many-body effects become significant. The structure of the condensed triples depends on the relative size of Efimov states to density scales. Unexpectedly, we find universal condensed triples in the limit where these scales are well-separated. Our findings provide a new framework for understanding dynamics in the unitary regime as the Bose-Einstein condensation of few-body composites.

description: We introduce a non commutative analog of the Bohr compactification. Starting from a general quantum group G we define a compact quantum group bG which has a universal property such as the universal property of the classical Bohr compactification for topological groups. We study the object bG in special cases when G is a classical locally compact group, dual of a classical group, discrete or compact quantum group as well a quantum group arising from a manageable multiplicative unitary. We also use our construction to give new examples of compact quantum groups.
A Most Intricate Department: The Commissary General of Military Stores Under Benjamin Flower and Samuel Hodgdon, 1777-1782
Creators: name: Barna, Frank Carl
Publisher: name: Digital Repository at the University of Maryland
Year: 1984

description: This thesis makes use of the little studied records of
the Military Stores or Ordnance, Department during the
American Revolution to examine the commonly held assumption
that the Continental Army was inadequately supplied with the
materials necessary for waging war. The evidence suggests
that contrary to this assumption, the Ordnance Department,
following the reforms of 1778, kept the army well supplied
with military stores.
This study will examine three phases which illustrate
the evolution of the Ordnance Department and the Army as a
whole. The first phase, 1775-1777, illustrates the extemporized
approach to war waged by Congressional committees
lacking in military knowledge and experience. From 1777 to
1779, we witness the maturation and professionalism that
evolved following the failure of the old colonial, citizenmilitia
approach to war. The final phase, 1779-1783,
provides the evidence that the professionalization worked.
Under the guidance of General Henry Knox and the
leadership of its two wartime administrators, Benjamin
Flower and samuel Hodgdon, the Ordnance Department, like the army it supported, evolved into a complex and sophisticated
organization. Under Knox and Hodgdon, the Department grew
from a divided and unresponsive system under political
controls imposed by Congress into an efficient organization
responsive to the army's needs. In many ways, the Department
became superior to the British system upon which it was
initially based and, except for spot shortages arising from
poor fiscal or political planning and transportation
problems, the Department kept the army well supplied with
the weaponry and military stores needed for victory.
Geometrized effective-one-body formalism for extreme-mass-ratio limits: Generic orbits

description: Compact objects inspiraling into supermassive black holes, known as extreme-mass-ratio inspirals, are an important source for future space-borne gravitational-wave detectors. When constructing waveform templates, usually the adiabatic approximation is employed to treat the compact object as a test particle for a short duration, and the radiation reaction is reflected in the changes of the constants of motion. However, the mass of the compact object should have contributions to the background. In the present paper, employing the effective-one-body formalism, we analytically calculate the trajectories of a compact object around a massive Kerr black hole with generally three-dimensional orbits and express the fundamental orbital frequencies in explicit forms. In addition, by constructing an approximate "constant" similar to the Carter constant, we transfer the dynamical quantities such as energy, angular momentum, and the "Carter constant" to the semilatus rectum, eccentricity, and orbital inclination with mass-ratio corrections. The linear mass-ratio terms in the formalism may not be sufficient for accurate waveforms, but our analytical method for solving the equations of motion could be useful in various approaches to building waveform models.

SPINN: Sparse, Physics-based, and partially Interpretable Neural Networks for PDEs

description: We introduce a class of Sparse, Physics-based, and partially Interpretable Neural Networks (SPINN) for solving ordinary and partial differential equations (PDEs). By reinterpreting a traditional meshless representation of solutions of PDEs we develop a class of sparse neural network architectures that are partially interpretable. The SPINN model we propose here serves as a seamless bridge between two extreme modeling tools for PDEs, namely dense neural network based methods like Physics Informed Neural Networks (PINNs) and traditional mesh-free numerical methods, thereby providing a novel means to develop a new class of hybrid algorithms that build on the best of both these viewpoints. A unique feature of the SPINN model that distinguishes it from other neural network based approximations proposed earlier is that it is (i) interpretable, in a particular sense made precise in the work, and (ii) sparse in the sense that it has much fewer connections than typical dense neural networks used for PDEs. Further, the SPINN algorithm implicitly encodes mesh adaptivity and is able to handle discontinuities in the solutions. In addition, we demonstrate that Fourier series representations can also be expressed as a special class of SPINN and propose generalized neural network analogues of Fourier representations. We illustrate the utility of the proposed method with a variety of examples involving ordinary differential equations, elliptic, parabolic, hyperbolic and nonlinear partial differential equations, and an example in fluid dynamics.

Production and evaporation of micro black holes as a link between mirror universes

description: It is shown that the equalization of temperatures between our and mirror sectors occurs during one Hubble time due to microscopic black hole production and evaporation in particle collisions if the temperature of the Universe is near the multidimensional Plank mass. This effect excludes the multidimensional Planck masses smaller than the reheating temperature of the Universe ($\sim10^{13}$ GeV) in the mirror matter models, because the primordial nucleosynthesis theory requires that the temperature of the mirror world should be lower than ours. In particular, the birth of microscopic black holes in the LHC is impossible if the dark matter of our Universe is represented by baryons of mirror matter. It excludes some of the possible coexisting options in particle physics and cosmology. Multidimensional models with flat additional dimensions are already strongly constrained in maximum temperature due to the effect of Kaluza-Klein mode (KK-mode) overproduction. In these models, the reheating temperature should be significantly less than the multidimensional Planck mass, so our restrictions in this case are not paramount. The new constraints play a role in multidimensional models in which the spectrum of KK-modes does not lead to their overproduction in the early Universe, for example, in theories with hyperbolic additional space.

description: Conventional ensemble learning combines students in the space domain. In this paper, however, we combine students in the time domain and call it time-domain ensemble learning. We analyze, compare, and discuss the generalization performances regarding time-domain ensemble learning of both a linear model and a nonlinear model. Analyzing in the framework of online learning using a statistical mechanical method, we show the qualitatively different behaviors between the two models. In a linear model, the dynamical behaviors of the generalization error are monotonic. We analytically show that time-domain ensemble learning is twice as effective as conventional ensemble learning. Furthermore, the generalization error of a nonlinear model features nonmonotonic dynamical behaviors when the learning rate is small. We numerically show that the generalization performance can be improved remarkably by using this phenomenon and the divergence of students in the time domain.

Από την άλλη πλευρά τα βραβεία που ακολούθησαν το ένα μετά το άλλο (τριπλό Smarties, Guardian, Sheffield, ABBY, Nibbies), το ότι μεταφράστηκε σε σαράντα δύο γλώσσες και φυσικά το ότι μεταφέρθηκε στον κινηματογράφο πυροδότησαν τον προβληματισμό σχετικά με τα θέματα που απασχολούν τους έφηβους μαθητές της Δευτεροβάθμιας εκπαίδευσης, όσον αφορά την ανάγνωση των βιβλίων της σειράς Χάρι Πότερ της Joan K. Rowling. Στόχος της έρευνας είναι να αναδειχθούν οι απόψεις, οι γνώμες και οι ιδέες των μικρών αναγνωστών του Χάρι Πότερ καθώς και το πώς αυτοί προσέλαβαν συγκεκριμένες θεματικές κατά την ανάγνωση των επτά βιβλίων. Η συλλογή δεδομένων πραγματοποιήθηκε με τη μέθοδο των ομάδων εστίασης και η ανάλυση αυτών έγινε με τη μέθοδο της ποιοτικής ανάλυσης περιεχομένου. Στην παρούσα έρευνα θα χρησιμοποιηθούν για την ποιοτική ανάλυση των δεδομένων ο συνδυασμός των δύο εκ των τριών παραδειγμάτων, αυτό της «εξήγησης» και της «δόμησης».
description: The seven books of Joan K. Rowling’s Harry Potter particularly troubled the Greek press and the majority of Greek public. I processed articles published on newspapers and magazines in order to reveal the reception of the series by the press. In addition, the awards rewarded to the series (Smarties, Guardian, Sheffield, ABBY, Nibbies), the fact that it was translated in forty two languages and that they were turned into movies touched off the scepticism about subjects that concern teen students related with the reading of Harry Potter books. The target of the research is to reveal the views, the opinion and ideas of the young readers of Harry Potter series as well as the way they receipted specific thematics during reading the seven books. The data collection took place on August 18th 2011 with the focus groups method. The participants were six pupils aged from 13 to 17 years old and they had read the seven books of Joan K. Rowling’s Harry Potter more than one time. The data analysis was fulfilled with the content analysis method and specifically with the examples of ‘explication’ and ‘structuring’.

description: We adapt continuous time random walk (CTRW) formalism to describe asset price evolution and discuss some of the problems that can be treated using this approach. We basically focus on two aspects: (i) the derivation of the price distribution from high-frequency data, and (ii) the inverse problem, obtaining information on the market microstructure as reflected by high-frequency data knowing only the daily volatility. We apply the formalism to financial data to show that the CTRW offers alternative tools to deal with several complex issues of financial markets.

description: We report a new determination of $\hat{q}$, the jet transport coefficient of the Quark-Gluon Plasma. We use the JETSCAPE framework, which incorporates a novel multi-stage theoretical approach to in-medium jet evolution and Bayesian inference for parameter extraction. The calculations, based on the MATTER and LBT jet quenching models, are compared to experimental measurements of inclusive hadron suppression in Au+Au collisions at RHIC and Pb+Pb collisions at the LHC. The correlation of experimental systematic uncertainties is accounted for in the parameter extraction. The functional dependence of $\hat{q}$ on jet energy or virtuality and medium temperature is based on a perturbative picture of in-medium scattering, with components reflecting the different regimes of applicability of MATTER and LBT. In the multi-stage approach, the switch between MATTER and LBT is governed by a virtuality scale $Q_0$. Comparison of the posterior model predictions to the RHIC and LHC hadron suppression data shows reasonable agreement, with moderate tension in limited regions of phase space. The distribution of $\hat{q}/T^3$ extracted from the posterior distributions exhibits weak dependence on jet momentum and medium temperature $T$, with 90\% Credible Region (CR) depending on the specific choice of model configuration. The choice of MATTER+LBT, with switching at virtuality $Q_0$, has 90\% CR of $240$ GeV/c. The value of $Q_0$, determined here for the first time, is in the range 2.0-2.7 GeV.

description: Στόχος της παρούσας εργασίας ήταν η μελέτη των τεχνικών πειθαρχίας που επιλέγουν οι γονείς των παιδιών με ακουστική απώλεια, σχολικής ηλικίας, να χρησιμοποιούν για να διαχειριστούν τις μη αποδεκτές συμπεριφορές που τα ίδια εκδηλώνουν. Ταυτόχρονα, διερευνήθηκε ο ρόλος των αντιλήψεων των γονέων για την προσωπικότητα των παιδιών τους, με βάση το θεωρητικό μοντέλο των Πέντε Παραγόντων, στην επιλογή αυτή. Το δείγμα αποτέλεσαν 91 γονείς, που χωρίστηκαν σε 2 ομάδες , 48 είχαν παιδιά με κανονική ακοή και οι 43 είχαν παιδιά με ακουστική απώλεια. Για τη συλλογή των δεδομένων χρησιμοποιήθηκαν κλίμακες αυτοαναφοράς, που συμπληρώθηκαν από τους γονείς. Σύμφωνα με τα αποτελέσματα, οι αντιλήψεις των γονέων για την προσωπικότητα των παιδιών τους φάνηκε, να σχετίζονται μερικώς μόνο, με τις στρατηγικές διαπαιδαγώγησης που επιλέγουν οι ίδιοι να εφαρμόζουν. Παράλληλα, παρουσιάζονται και αρκετές διαφοροποιήσεις στις σχέσεις μεταξύ των δυο παραπάνω μεταβλητών ανάμεσα στις δυο ομάδες, ενώ δεν υπήρξε διαφοροποίηση στο είδος των τεχνικών πειθαρχίας μεταξύ τους. Στατιστικώς σημαντικές επιδράσεις διαπιστώθηκαν και ως προς κάποια δημογραφικά χαρακτηριστικά γονέων και παιδιών στις υπό εξέταση μεταβλητές.
description: The aim of this study was to examine the parental choice of discipline practices selected, to manage their school-age children’s inappropriate behaviors. Moreover regarding this choice, the role of parental perceptions for their children's personality is examined, based on the theoretical model of Five Factors. The sample comprised 91 parents divided into 2 groups, where 48 parents had children with normal hearing and 43 parents had children with hearing loss. Data was collected using self-report scales, completed by the parents. According to the results, the perceptions of parents in their children's personality appeared to be only partially associated with the discipline practices chosen to be applied. Additionally, several differences in the correlation of the two aforementioned variables between the two groups was observed, while there was no variation in the type of discipline practices among them. Statistically significant effects were also found in some demographic characteristics of parents and children on the relevant variables

description: Moiré patterns with a superlattice potential can be formed by vertically stacking two layered materials with a relative twist or lattice constant mismatch. The moiré superlattice can generate flat bands that result in new correlated insulating, superconducting, and topological states. Strong electron correlations, tunable by the fractional filling, have been observed in both graphene and transition metal dichalcogenide (TMD) based systems. In addition, in TMD based systems, the moiré potential landscape can trap interlayer excitons (IX) at specific atomic registries. Here we report that spatially isolated trapped IX in a molybdenum diselenide/tungsten diselenide heterobilayer device provide a sensitive optical probe of carrier filling in their immediate environment. By mapping the spatial positions of individual trapped IX, we are able to spectrally track the emitters as the moiré lattice is filled with excess carriers. Upon initial doping of the heterobilayer, neutral trapped IX form charged IX (IX trions) uniformly with a binding energy of ~7 meV. Upon further doping, the empty superlattice sites sequentially fill, creating a Coulomb staircase: stepwise changes in the IX trion emission energy due to Coulomb interactions with carriers at nearest neighbour moiré sites. This non-invasive, highly local technique can complement transport and non-local optical sensing techniques to characterise Coulomb interaction energies, visualise charge correlated states, or probe local disorder in a moiré superlattice.

description: An algorithm for fast calculation of the Coulombic forces and energies of point particles with free boundary conditions is proposed. Its calculation time scales as N log N for N particles. This novel method has lower crossover point with the full O(N^2) direct summation than the Fast Multipole Method. The forces obtained by our algorithm are analytical derivatives of the energy which guarantees energy conservation during a molecular dynamics simulation. Our algorithm is very simple.

description: Ο ρόλος της γραμματικής στην διδασκαλία της ξένης γλώσσας, αποτελεί εδώ και αρκετές δεκαετίες, ένα αντιφατικό ζήτημα μεταξύ των αντιπάλων και των υποστηρικτών της τυπικής διδασκαλίας της γραμματικής. Η διπλωματική εργασία αποτελεί μία θεωρητική παρουσίαση αφιερωμένη στην ερώτηση, εάν αν η χρήση, εφαρμογή των κανόνων της γραμματικής στη διδασκαλία μιας γλώσσας, μπορεί να συμβάλει σε επιτυχή εκμάθηση της ξένης γλώσσας. Μια επισκόπηση των μεθόδων διδασκαλίας της γραμματικής, παρουσιάζει την πολυμορφία της σημασίας όπως και τον τρόπο της μετάδοσης, ο οποίος, κατά τη διάρκεια των χρόνων, έχει υποστεί διαφορετικές εξελίξεις. Σημαντικές πτυχές είναι η περιγραφή των διαφορετικών θέσεων, οι οποίες υπογραμμίζουν την σαφή ή την παραγωγική προσέγγιση και απαγωγική ή επαγωγική μετάδοση της γραμματικής. Ακόμη και στα τρέχουσα προγράμματα σπουδών διδασκαλίας ξένων γλωσσών, είτε του γερμανικού είτε του ελληνικού συγκείμενου, προτείνονται κατευθυντήριες γραμμές, για την διαδικασία μετάδοσης της γραμματικής, σύμφωνα με τις προδιαγραφές του κοινού Ευρωπαϊκού Πλαισίου Αναφοράς Γλωσσών. Επιλεγμένα αποτελέσματα από τις μελέτες, δεν έφεραν ξεκάθαρα αποτελέσματα, σχετικά με το αν η κατανόηση και η γνώση των κανόνων γραμματικής, προωθεί πράγματι την επικοινωνιακή ικανότητα του μαθητή μιας ξένης γλώσσας.
description: The role of grammar in language teaching has been since several decades a contradictory topic between the opponents and the supporters of formal grammar teaching. The thesis is a theoretical representation, dedicated to the question, whether the use of the grammar rules in language teaching can lead to successful learning of a foreign language. An overview of the grammar teaching methods, represents the diversity of the importance and the way of teaching the grammar, which has been evolving differently over the years. Substantial aspects are here the representation of different positions, which emphasize differently the explicit / implicit or the deductive / inductive Grammar teaching. Even in the curricular Text - Books of foreign language teaching, in both contexts, German and Greek, are Guidelines recommended, in accordance with the instructions, by the common European Reference Framework, proposed for the teaching process. Selected results of studies, can’t provide conclusively an irrefutable result, whether indeed the insight and the good command of grammatical rules, the communicative competence, of foreign language learners is promoting and stimulating.

description: We study how the evolution of a Dark Energy Quintessence fluid is modified by the presence of a matter inhomogeneity. To do so, we study linear perturbations of a flat FLRW background containing dust and a slowly rolling scalar field. Under the assumptions of spherical symmetry and a static density contrast, \textit{i.e.} $\dotδ=0$, we obtain simple analytical solutions for perturbations in the matter and dark energy-dominated epochs. As a consequence, we show that perturbations of the scalar field, if a coupling \textit{à la} Bekenstein is assumed, trigger a spatial dependence of the fine-structure "constant" which then varies as $Δα\propto 1/r$. We finally highlight that such variations can be constrained with spectroscopic observations of stars from within our galaxy, therefore offering a new probe of the nature of Dark Energy.

description: Rapid urbanization and population growth in Bangladesh, are increasing vulnerability to hazards like floods, earthquakes, fires, and water logging. This has led to social, physical, economic, and environmental consequences, such as disruption of life, water scarcity, infrastructure damage, and extinction of wildlife. This study examines the impact of unplanned urbanization on water scarcity in Bangladesh's rapidly growing cities, assesses its effect on drainage systems, and proposes strategies for mitigation. This study conducted a comprehensive analysis of unplanned urbanization in Bangladesh, examining its effects on population, water sources, and drainage systems. The research assessed the interconnections between urbanization, water scarcity, and flooding by drawing on secondary data from various sources. Additionally, it proposed strategies to mitigate these challenges and promote sustainable urban development. Finally, some possible and practical solutions for managing urbanization have been suggested to tackle water scarcity and drainage problems in Bangladesh.

description: We have observed a 3 degree x 3 degree area centered on the M81/M82 group of galaxies using the Robert C. Byrd Green Bank Telescope (GBT) in a search for analogs to the High Velocity Clouds (HVCs) of neutral hydrogen found around our galaxy. The velocity range from -605 to -85 km/s and 25 to 1970 km/s was searched for HI clouds. Over the inner 2 degrees x 2 degrees the 7-sigma detection threshold was 9.6 x 10^5 M_sun. We detect 5 previously unknown HI clouds associated with the group, as well as numerous associated filamentary HI structures, all lying in the range -105 < V_helio < +280 km/s. From the small angular distance of the clouds to group members, and the small velocity difference between group members and clouds, we conclude that the clouds are most likely relics of ongoing interactions between galaxies in the group.
