Stress dependent thermal pressurization of a fluid-saturated rock
Creators: name: Ghabezloo, Siavash

Publisher: name: arXiv
Year: 2008
Subjects: subject: Geophysics (physics.geo-ph)
subject: FOS: Physical sciences

description: Temperature increase in saturated porous materials under undrained conditions leads to thermal pressurization of the pore fluid due to the discrepancy between the thermal expansion coefficients of the pore fluid and of the solid matrix. This increase in the pore fluid pressure induces a reduction of the effective mean stress and can lead to shear failure or hydraulic fracturing. The equations governing the phenomenon of thermal pressurization are presented and this phenomenon is studied experimentally for a saturated granular rock in an undrained heating test under constant isotropic stress. Careful analysis of the effect of mechanical and thermal deformation of the drainage and pressure measurement system is performed and a correction of the measured pore pressure is introduced. The test results are modelled using a non-linear thermo-poro-elastic constitutive model of the granular rock with emphasis on the stress-dependent character of the rock compressibility. The effects of stress and temperature on thermal pressurization observed in the tests are correctly reproduced by the model.

description: The Southern Photometric Local Universe Survey (S-PLUS) is a novel project that aims to map the Southern Hemisphere using a twelve filter system, comprising five broad-band SDSS-like filters and seven narrow-band filters optimized for important stellar features in the local universe. In this paper we use the photometry and morphological information from the first S-PLUS data release (S-PLUS DR1) cross-matched to unWISE data and spectroscopic redshifts from Sloan Digital Sky Survey DR15. We explore three different machine learning methods (Gaussian Processes with GPz and two Deep Learning models made with TensorFlow) and compare them with the currently used template-fitting method in the S-PLUS DR1 to address whether machine learning methods can take advantage of the twelve filter system for photometric redshift prediction. Using tests for accuracy for both single-point estimates such as the calculation of the scatter, bias, and outlier fraction, and probability distribution functions (PDFs) such as the Probability Integral Transform (PIT), the Continuous Ranked Probability Score (CRPS) and the Odds distribution, we conclude that a deep-learning method using a combination of a Bayesian Neural Network and a Mixture Density Network offers the most accurate photometric redshifts for the current test sample. It achieves single-point photometric redshifts with scatter ($σ_\text{NMAD}$) of 0.023, normalized bias of -0.001, and outlier fraction of 0.64% for galaxies with r-auto magnitudes between 16 and 21.

Functional medium-dependence of the nonrelativistic optical model potential
Creators: name: Arellano, H. F.
name: Bauge, Eric
Publisher: name: arXiv
Year: 2007
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: By examining the structure in momentum and coordinate space of a two-body interaction spherically symmetric in its local coordinate, we demonstrate that it can be disentangled into two distinctive contributions. One of them is a medium-independent and momentum-conserving term, whereas the other is functionally --and exclusively-- proportional to the radial derivative of the reduced matrix element. As example, this exact result was applied to the unabridged optical potential in momentum space, leading to an explicit separation between the medium-free and medium-dependent contributions. The latter does not depend on the strength of the reduced effective interaction but only on its variations with respect to the density. The modulation of radial derivatives of the density enhances the effect in the surface and suppresses it in the saturated volume. The generality of this result may prove to be useful for the study of surface-sensitive phenomena.

description: Dedicated 'Stage IV' observatories will soon observe the entire extragalactic sky, to measure the 'cosmic shear' distortion of galaxy shapes by weak gravitational lensing. To measure the apparent shapes of those galaxies, we present an improved version of the Fourier Power Function Shapelets (FPFS) shear measurement method. This now includes analytic corrections for sources of bias that plague all shape measurement algorithms: including noise bias (due to noise in nonlinear combinations of observable quantities) and selection bias (due to sheared galaxies being more or less likely to be detected). Crucially, these analytic solutions do not rely on calibration from external image simulations. For isolated galaxies, the small residual $\sim$$10^{-3}$ multiplicative bias and $\lesssim$$10^{-4}$ additive bias now meet science requirements for Stage IV experiments. FPFS also works accurately for faint galaxies and robustly against stellar contamination. Future work will focus on deblending overlapping galaxies. The code used for this paper can process $>$$1000$ galaxy images per CPU second and is available from https://github.com/mr-superonion/FPFS.

(Fig. 5 A-C)
DESCRIPTION
Intergenicula cylindrical, measuring 350 to 1092 µm in length and134 to180 µm in diameter.The rows of cells in the core region are rectangular in shape and measure 18 to 24 µm in length and 8 to 12 µm in diameter. Cell fusions are prominent (Table 1).
REMARKS
Based on the diagnostic features, the form is assignable to the genus Corallina. However, owing to lack of preservation of adequate taxonomic characteristics it is not possible to assign it to any known species of the genus. Different species of Corallina have been reported earlier from the Miocene of Kutch Basin, India (Kundal & Humane 2003).

description: In this work, we perform a follow-up and comprehensive study on the structural details and formation mechanism of chemical vapor deposition (CVD) synthesized one-dimensional (1D) van der Waals heterostructures. Edge structures, nucleation sites, crystal epitaxial relationships are clearly revealed using transmission electron microscopy (TEM). This is achieved by the direct synthesis of heteronanotubes on a CVD-compatible Si/SiO2 TEM grid, which enabled a transfer-free and non-destructive access to many intrinsic structural details. In particular, we have distinguished different shaped boron nitride nanotube (BNNT) edges, which are confirmed, by electron diffraction at the same location, to be strictly associated with its own chiral angle and polarity. We also demonstrate the importance of surface cleanness and isolation for the formation of perfect 1D heterostructures. Furthermore, we elucidate the handedness correlation between SWCNT template and BNNT crystals. This work not only provides an in-depth understanding of this new 1D heterostructure material group, but also, in a more general perspective, serves as an interesting investigation on crystal growth on highly curved (radius of a couple of nm) atomic substrates.

description: We investigate crystalline order on a two-dimensional paraboloid of revolution by assembling a single layer of millimeter-sized soap bubbles on the surface of a rotating liquid, thus extending the classic work of Bragg and Nye on planar soap bubble rafts. Topological constraints require crystalline configurations to contain a certain minimum number of topological defects such as disclinations or grain boundary scars whose structure is analyzed as a function of the aspect ratio of the paraboloid. We find the defect structure to agree with theoretical predictions and propose a mechanism for scar nucleation in the presence of large Gaussian curvature.

description: We employ the first fully three-dimensional simulation to study the role of magnetic fields and ion-neutral friction in regulating gravitationally-driven fragmentation of molecular clouds. The cores in an initially subcritical cloud develop gradually over an ambipolar diffusion time while the cores in an initially supercritical cloud develop in a dynamical time. The infall speeds on to cores are subsonic in the case of an initially subcritical cloud, while an extended (\ga 0.1 pc) region of supersonic infall exists in the case of an initially supercritical cloud. These results are consistent with previous two-dimensional simulations. We also found that a snapshot of the relation between density (rho) and the strength of the magnetic field (B) at different spatial points of the cloud coincides with the evolutionary track of an individual core. When the density becomes large, both relations tend to B \propto ρ^{0.5}.

(Fig. 5D)
DESCRIPTION
Encrusting to warty growth form, thallus monomerous, dorsiventral, non-coaxial VC. The cells of VC are rectangular in shape that measure 8 to 16 µm in length and 3 to 8 µm in diameter. Cells of PF are more or less squarish with no distinct zonation, 5 to 12 µm in length and 4 to 10 µm in diameter. Cell fusions present. Epithallial cells and trichocytes are indiscernible. Sporangia elliptical, formed within calcified compartments and grouped into sori. Each sporangium measures 80 to 120 µm in height and 35 to 48 µm in diameter (Table 1).
REMARKS
The specimen is comparable to Sporolithon airoldii described from the lower Oligocene of NW Iran (Basso et al. 2019) in having small size of the vegetative cells and other anatomical features, but the maximum length of the sporangia exceeds that of the specimens described by Basso et al. (2019) as well as the type material of S. airoldii. Vannucci et al. (2010) re-described S. airoldii from the upper Rupelian-Chattian of Sassello while re-assessing Airoldi’s (1932) specimens. Sporolithon airoldii was recorded earlier from the Oligocene of Molare Formation of the Tertiary Piedmont Basin, NW Italy (Vannucci et al. 2010), from the lower and middle Rupelian of Prasco and Ovrano, Alessandria (Mastrorilli 1968), Val Lemme, Carrosio, Alessandria (Fravega et al. 1988), from the upper Rupelian to Chattian of Sassello, Savona (Airoldi 1932; Fravega et al. 1987), from the upper Burdigalian to Serravallian of St. Florent, N. Corsica and Bonifacio, Cala de Labra, S. Corsica (Mastrorilli in Bellini & Mastrorilli 1975) and from the lower Oligocene of NW Iran (Basso et al. 2019).

description: Flexoelectricity is a type of ubiquitous and prominent electromechanical coupling, pertaining to the response of electrical polarization to mechanical strain gradients while not restricted to the symmetry of materials. However, large elastic deformation in most solids is usually difficult to achieve and the strain gradient at minuscule is challenging to control. Here we exploit the exotic structural inhomogeneity of grain boundary to achieve a huge strain gradient (~ 1.2 nm-1) within 3 ~ 4 unit-cells, and thus obtain atomic-scale flexoelectric polarization up to ~ 38 μC/cm2 at a 24 LaAlO3 grain boundary. The nanoscale flexoelectricity also modifies the electrical activity of grain boundaries. Moreover, we prove that it is a general and feasible way to form large strain gradients at atomic scale by altering the misorientation angles of grain boundaries in different dielectric materials. Thus, engineering of grain boundaries provides an effective pathway to achieve tunable flexoelectricity and broadens the electromechanical functionalities of non-piezoelectric materials.

description: In this paper we consider a generalization of a well known result by Veronese about rational normal curves. More precisely, given a collection of linear spaces in $\PP^n$ we study the existence of rational normal curves intersecting each component of the configuration maximally. We introduce different methods to show existence and non-existence of such curves. We also show how to apply these techniques to the study of defectivity of Segre-Veronese varieties.

description: Unique electronic properties of self-organized Au atom chains on Ge(001) in novel c(8x2) long-range order are revealed by scanning tunneling microscopy. Along the nanowires an exceptionally narrow conduction path exists which is virtually decoupled from the substrate. It is laterally confined to the ultimate limit of single atom dimension, and is strictly separated from its neighbors, as not previously reported. The resulting tunneling conductivity shows a dramatic inhomogeneity of two orders of magnitude. The atom chains thus represent an outstandingly close approach to a one-dimensional electron liquid.

title: The effect of dual policy interventions on the rate of central venous catheter associated infections in adult stem cell transplant patients with hematological malignancy in Newfoundland and Labrador
Creators: name: Dunne, Tom
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: Background: Central venous catheters (CVCs) have a risk of infectious complications. With a suspected rise in cases in stem cell transplants, Eastern Health implemented two changes to reduce infections in June 2018: (1) earlier CVC insertion and (2) restriction of CVC access to specially trained nurses. The primary outcome was the difference in rate of CVC-associated infections per 1,000 catheter-days. Secondary outcomes included identifying modifiable risk factors to target for future clinical interventions to lower complication rates. Methods: This single-centre observational before-and-after study included adult SCT patients with CVCs was divided into the pre- and post-intervention cohorts between 2014-2020. A complete chart review was conducted from the period of first CVC insertion through the endpoint of CVC removal or patient death to identify all incident cases of CVC associated infection, risk factors, cultures and 90-day all-cause mortality. Results: The study demonstrated an incidence of catheter-related bloodstream infections (CR-BSI) of 21.3% in the pre-intervention group and 25.0% in the postintervention group (p=0.681). CR-BSI per 1000 catheter-days was similarly 2.39 and 3.39 (p=0.628). Neither was statistically significant. The study identified a novel risk factor in preceding history of bacteremia (HR 763.1, p=0.039). In conclusion we were unable to demonstrate a reduction in infectious complications associated with the two interventions.

We prove that the class of all orthodox semigroups in which every nonidempotent element has infinite order is lattice closed.

description: Background: The Public Health Agency of Canada published a strategic document recognising the elements associated with person-centred dementia care, including interactions with stakeholders and research mandates. One essential element identified was advanced therapies, containing non-pharmacological interventions, such as creative arts-based interventions. Objective: This thesis investigates the impact of creative arts-based interventions on individuals with dementia, living in residential care through a scoping review (ScR) and a mixed-methods systematic review (MMSR). Methods: The ScR surveyed the current literature base to identify which creative arts-based interventions improved the personhood, quality of life and well-being of persons with dementia (PwD); five studies were included. The MMSR explored the impact of dance interventions on the symptoms of dementia on persons with Alzheimer’s disease and related dementias, as dance was unrepresented in the ScR; three studies were included. Both reviews were narratively synthesized due to the heterogeneity in the results. Results: Each included study spoke of the impact the creative arts had on the PwD and which element(s) of their health improved. Results also showed that the creative arts were beneficial for the personhood of the PwD (ScR) and for decreasing symptoms while promoting the person (MMSR). Conclusion: We must continue to look past the condition and recognize that creativity, psychosocial needs, and creative arts are all interconnected in promoting the personhood of PwD. Creative arts-based interventions can be designed to promote the individual creativity of the person and showcase their intact abilities.

DESCRIPTION
Lumpy to protuberant thallus, VC filaments indiscernible. The peripheral filaments (PF) show horizontal layers of elliptical cells. Cell fusions are present in the PF, the cells of PF measure 14 to 26 µm in length and 10 to 12 µm in diameter. Sporangia grouped in sori, individual sporangia measuring 30 to 36 µm in diameter and 59 to 68 µm in height (Table 1).
REMARKS
Vannucci et al. (2000) revised and re-documented this species of Sporolithon and transferred Airoldi’s (1932) Archaeolithothamnium praeerythraeum under the genus Sporolithon with a new combination. The species has been identified from the late Eocene to early Oligocene of Italy and Bulgaria (Francavilla et al. 1970; Bakalova 1983). The overall thallus organization, shape and size of the sporangia and the arrangement of the sporangia are closely comparable to the middle Miocene specimens recorded by Vannucci et al. (2000) and Chelaru & Bucur (2016).

Thus, it is the primary source of employment worldwide from the food and beverage industry, counting these over a million employees in substantial multinational food and drink manufacturing companies – fast food service crews. Thus, this study intended to express service crews' insights on the challenges they are regularly facing. This study also aims to describe how pandemic makes the service crews' personal lives and work-life even more complicated. Interpretative Phenomenological Analysis (IPA) was employed to describe the experiences of the participants. Hence, the study's findings were: (1) Service crews experienced many challenges during the pandemic. They had a hard time getting used to the new normal, and they feared getting infected with the virus that may cause them or their loved one's death. (2) For a long time, they had to work in food chains; service crews come up with several coping mechanisms such as positive-thinking and adjustment. Service crews learned that having a healthy mindset helps a lot when dealing with a challenging atmosphere, and they also learned the adjustments they had to make when facing circumstances. (3) Then, although the pandemic rendered problems and changes, service crews took this as an opportunity to take a break despite having worries about financial resources. Service Crews' positive experiences during the pandemic are about the closer relationship they build between themselves, their families, their co-workers, and with God.

description: A simple afterburner including radial flow to the randomized transverse momentum obtained from event generators, Pythia and Hijing, has been implemented to calculate the $p/π$ ratios and compare them with available data. A coherent trend of qualitative agreement has been obtained in $pp$ collisions and in $Au+Au$ for various centralities. Those results indicate that the radial flow does play an important role in the so called baryon puzzle anomaly.

Development, diapause and seasonal ecology of the insect parasite, apanteles rubecula (hymenoptera; braconidae)
Creators: name: Nealis, Vincent Graham
Publisher: name: University of British Columbia
Year: 2010

description: Apanteles rubecula is a solitary insect parasite of Pier is rapae (small cabbage white butterfly, imported cabbageworm). The parasite has been successfully introduced to Australia and Vancouver, Canada but has failed to become established at other North American release sites. This practical problem illustrates a fundamental aspect of insect ecology. The seasonal biology of insects is interpreted here as an interaction of responses to ambient conditions. Emphasis centers on the rates at which life history phenomena occur and the importance of the insect's biological chronometers on the outcome of its ecological relationships with its host and its local climate. Comparisons are made between Canberra, Australia and Vancouver, Canada. The parasite's developmental response to temperature is similar in Canberra and Vancouver but the host response differs. Canberra A. rubecula have a longer generation time relative to the host at low temperatures, but shorter generation times at higher, midseason temperatures. Vancouver parasites always have faster generation times than their hosts but the season is truncated in August by a diapause response to daylengths shorter than I5h. The beginning of the season is delayed until late May by the high thermal requirement to terminate diapause. These local responses to temperature and photoperiod result in different phenologies which, while appropriate locally, are disastrous elsewhere. The failure of North American attempts to establish Vancouver A. rubecula is attributed to the diapause characteristics of the released insects. They entered diapause while ambient temperatures remained warm enough for morphogenesis and were unable to survive the obligatory period to diapause termination. Manipulation of the diapause response is one technique in ecological pest management. A methodology for a breeding program and its analysis is presented. Practical suggestion for biological control efforts are made and the role of individual physiological responses in insect seasonal ecology are discussed.

description: Oysters are foundation species utilized in Living Shorelines projects due to their potential to attenuate wave energy and stabilize shorelines. These potential benefits have created recent interest in restoring Olympia oysters (Ostrea lurida), the only oyster species native to the US west coast. However, little is yet known about what site characteristics are necessary to successfully restore functional, self-maintaining Olympia oyster beds. Furthermore, the degree to which Olympia oyster beds attenuate wave energy is not yet known. I examined the effects of annual recruitment, eelgrass presence, and human activity on restored oyster bed integrity and adult oyster density at four sites in Newport Bay, California between 2019-2021. I assessed wave attenuation and shoreline stabilization by measuring the height of boat wakes passing over oyster beds and associated control plots and by tracking changes in grain size profiles upshore of the oyster beds. Oyster beds at sites with higher levels of destructive human activity experienced more rapid bed breakdown, but breakdown was reduced when eelgrass density was higher. Oyster density increased with higher larval recruitment during the previous year, but this relationship weakened as bed breakdown increased. I did not find evidence of wave attenuation by the restored beds. The results of my study suggest that Olympia oyster beds restored at sites with high levels of human activity require additional protective measures to prevent premature breakdown, especially when year-to-year recruitment is variable.

Paralona pigra

description: 55. * Paralona pigra (Sars, 1862)
(Fig. 6A–C)
Localities and specimens found: 92 – 1♀.
Distribution and ecology. Paralona pigra (formerly most commonly known as Chydorus piger Sars, 1862) is today the only member of the genus. It is recorded from the temperate and northern regions of Eurasia, North and South America, Africa and New Guinea (Dumont & Smirnov 1996; Smirnov 1996; Korovchinsky et al. 2021b). There are no reports of findings of this chydorid within the Oriental biogeographic area, taking into account all available synonyms (Kotov et al. 2013a; Błędzki & Rybak 2016; WoRMS Editorial Board 2024). It therefore appears to be the first record of the species not only in Vietnam, but in the entire region.
Paralona pigra is considered a benthic species. It primarily occurs in oligotrophic and mesotrophic lakes and ponds on sandy and silty sediments. The species is also found in groundwater (Fryer 1968; Smirnov 1996; Kotov 2006; Korovchinsky et al. 2021b). The only female from our material was discovered in a low-flow section of a mountain river in December at a water temperature of approximately 16°C (see Appendix 1), which is quite consistent with habitat conditions for the species at more northern latitudes.
Remarks. Paralona pigra is not yet a fully studied taxon and needs revision. Because its specimens from different parts of the world have notable morphological differences, this crustacean may in fact represent a complex of related species (Dumont & Smirnov 1996; Smirnov 1996; Korovchinsky et al. 2021b). For example, some populations of the species are characterized by the presence of a spine (or several spines) in the posterior-ventral corners of the valves, whereas others do not have such spines (Smirnov 1996). Our Vietnamese female has a distinct spine on each valve (Fig. 6A, C).

description: Breaking Hermiticity in topological systems gives rise to intriguing phenomena, such as the exceptional topology and the non-Hermitian skin effect. In this work, we study a non-Hermitian topological crystalline insulator sitting on the Kekulé-modulated honeycomb lattice with balanced gain and loss. We find that the gaplessness of the topological edge states in the non-Hermitian system is insensitive to edge geometries under moderate strength of gain and loss, unlike the cases of Hermitian topological crystalline insulators that depend on edge geometries crucially. We focus on two types of gain and loss configurations, which are $PT$-symmetric and $PT$-asymmetric, respectively. For the $PT$-symmetric configuration, the Dirac point of the topological edge states in the Hermitian molecular-zigzag-terminated ribbons splits into a pair of exceptional points. The edge gap in the Hermitian armchair-terminated ribbons vanishes and a Dirac point forms as far as moderate gain and loss is induced. The band gaps of edge and bulk states in the Hermitian armchair-terminated ribbons close simultaneously for the $PT$-asymmetric configuration.

Major conventional scenes in late sixteenth-century Italian and French pastoral drama
Creators: name: Niccoli, Gabriel Adriano
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of the present work is to analyze the function of three major conventional scenes, broadly termed topoi, in three pastoral plays: the Aminta of Tasso, Guarini's Pastor Fido and the Bergerie by Montchrestien. The initial part of this study presents the basic features of pastoral drama in the last quarter of the sixteenth century in both Italy and France. It is concerned especially with some of the theoretical dicta expressed at that time and with the manner in which they may have influenced the handling of major dramatic scenes by different playwrights. Particular attention is devoted to the acrimonious querelle that took place around the Pastor Fido. The successful defense of Guarini's tragicommedia pastorale was, in fact, of great significance in the development of the pastoral dramatic genre because it guaranteed the dignity of pastoral tragicomedy alongside the established forms of tragedy and comedy. The main part of the dissertation is a detailed textual study of three major recurring scenes in pastoral drama; namely, those involving Cupid, the Golden Age theme and the Satyr. The use of each of these famous topological structures reveals, of course, the dramatist's conception of them and, more importantly, his audience's expectations. Whether a particular topos is elaborated more decoratively than dramatically, it must have an integral function in the structure of the play. Contrary to the entrenched opinion on pastoral drama, these were plays that were written in order to be staged, an important fact which is too often forgotten and only recently, thanks to the work of such critics as Clubb, Igliozzi and Dalla Valle, has been given due emphasis.

description: In this paper, based on a weighted projection of bipartite user-object network, we introduce a personalized recommendation algorithm, called the \emph{network-based inference} (NBI), which has higher accuracy than the classical algorithm, namely \emph{collaborative filtering}. In the NBI, the correlation resulting from a specific attribute may be repeatedly counted in the cumulative recommendations from different objects. By considering the higher order correlations, we design an improved algorithm that can, to some extent, eliminate the redundant correlations. We test our algorithm on two benchmark data sets, \emph{MovieLens} and \emph{Netflix}. Compared with the NBI, the algorithmic accuracy, measured by the ranking score, can be further improved by 23% for \emph{MovieLens} and 22% for \emph{Netflix}, respectively. The present algorithm can even outperform the \emph{Latent Dirichlet Allocation} algorithm, which requires much longer computational time. Furthermore, most of the previous studies considered the algorithmic accuracy only, in this paper, we argue that the diversity and popularity, as two significant criteria of algorithmic performance, should also be taken into account. With more or less the same accuracy, an algorithm giving higher diversity and lower popularity is more favorable. Numerical results show that the present algorithm can outperform the standard one simultaneously in all five adopted metrics: lower ranking score and higher precision for accuracy, larger Hamming distance and lower intra-similarity for diversity, as well as smaller average degree for popularity.

description: Numerical simulations predict the existence of old Tidal Dwarf Galaxies (TDGs) that would have survived several Gyr after the collision lying at their origin. Such survivors, which would by now have become independent relaxed galaxies, would be ideal laboratories, if nearby enough, to tackle a number of topical issues, including the distribution of Dark Matter in and around galaxies. However finding old dwarf galaxies with a confirmed tidal origin is an observational challenge. A dwarf galaxy in the Virgo Cluster, VCC 2062, exhibits several unusual properties that are typical of a galaxy made out of recycled material. We discuss whether it may indeed be a TDG. We analysed multi-wavelength observations of VCC 2062, including an IRAM CO map, an optical spectrum of its HII regions, GALEX ultraviolet and archival broad-band and narrow-band optical images as well as a VLA HI datacube, originally obtained as part of the VIVA project. VCC 2062 appears to be the optical, low surface brightness counterpart of a kinematically detached, rotating condensation that formed within an HI tail apparently physically linked to the disturbed galaxy NGC 4694. In contrast to its faint optical luminosity, VCC 2062 is characterised by strong CO emission and a high oxygen abundance more typical of spiral disks. Its dynamical mass however, is that of a dwarf galaxy. VCC 2062 was most likely formed within a pre-enriched gaseous structure expelled from a larger galaxy as a result of a tidal interaction. The natural provider for the gaseous tail is NGC 4694 or rather a former companion which subsequently has been accreted by the massive galaxy. According to that scenario, VCC 2062 has been formed by a past tidal encounter. Since its parent galaxies have most probably already totally merged, it qualifies as an old TDG.
