description: In this paper, the impact of demosaicing on gradient extraction is studied and a gradient-based feature extraction pipeline based on raw Bayer pattern images is proposed. It is shown both theoretically and experimentally that the Bayer pattern images are applicable to the central difference gradient-based feature extraction algorithms without performance degradation, or even with superior performance in some cases. The color difference constancy assumption, which is widely used in various demosaicing algorithms, is applied in the proposed Bayer pattern image-based gradient extraction pipeline. Experimental results show that the gradients extracted from Bayer pattern images are robust enough to be used in histogram of oriented gradients (HOG)-based pedestrian detection algorithms and shift-invariant feature transform (SIFT)-based matching algorithms.

description: Magnetically-arrested disks (MADs) appear when accretion flows are supplied with a sufficient amount of magnetic flux. In this work, we use results of magnetohydrodynamic simulations to set the configuration of the magnetic field and investigate the dynamics and radiative properties of the resulting accretion flow (i.e., without that of the jet) of MAD. The method developed here is applied to both the MAD and the standard and normal evolution (SANE) accretion flow with or without large scale magnetic fields. For the radiative processes, we include synchrotron, bremsstrahlung and Compton scattering. We find that, in general, MAD accretion flows have similar spectra to those of the SANE, which complicates the task of distinguishing MADs from SANEs. At the same accretion rates, MADs are systematically brighter than SANEs. However, the critical accretion rate above which the hot solution ceases to exist is lower in MAD. Consequently, the maximum luminosity the MAD can reach is comparable but slightly lower than that of SANE, and the dependence on the magnetic flux is weak. We then discuss implications of our results for active galactic nuclei and accreting black-hole binaries.

description: We measured the ionized-gas and stellar kinematics along the major and minor axis of a sample of 10 early-type spirals. Much to our surprise we found a remarkable gas velocity gradient along the minor axis of 8 of them. According to the kinematic features observed in their ionized-gas velocity fields, we divide our sample galaxies in three classes of objects. (i) NGC 4984, NGC 7213, and NGC 7377 show an overall velocity curve along the minor axis without zero-velocity points, out to the last measured radius, which is interpreted as due to the warped structure of the gaseous disk. (ii) NGC 3885, NGC 4224, and NGC 4586 are characterized by a velocity gradient along both major and minor axis, although non-zero velocities along the minor axis are confined to the central regions. Such gas kinematics have been explained as being due to non-circular motions induced by a triaxial potential. (iii) NGC 2855 and NGC 7049 show a change of slope of the velocity gradient measured along the major axis (which is shallower in the center and steeper away from the nucleus), as well as non-zero gas velocities in the central regions of the minor axis. This has been attributed to the presence of a kinematically-decoupled gaseous component in orthogonal rotation with respect to the galaxy disk, namely an inner polar disk. The case and origin of inner polar disks are discussed and the list of their host galaxies is presented.

description: We consider three fundamental issues in quantum gravity: (a) the black hole information paradox (b) the unboundedness of entropy that can be stored inside a black hole horizon (c) the relation between the black hole horizon and the cosmological horizon. With help from the small corrections theorem, we convert each of these issues into a sharp conflict. We then argue that all three conflicts can be resolved by the following hypothesis: {\it the vacuum wavefunctional of quantum gravity contains a `vecro' component made of virtual fluctuations of configurations of the same type that arise in the fuzzball structure of black hole microstates}. Further, if we assume that causality holds to leading order in gently curved spacetime, then we {\it must} have such a vecro component in order to resolve the above conflicts. The term vecro stands for `Virtual Extended Compression-Resistant Objects', and characterizes the nature of the vacuum fluctuations that resolve the puzzles. It is interesting that puzzle (c) may relate the role of quantum gravity in black holes to observations in the sky.

The idea of adaptation in transaction cost economics : an application to stakeholder theory
Creators: name: Valentinov, Vladislav

Publisher: name: Universitäts- und Landesbibliothek Sachsen-Anhalt
Year: 2024
Subjects: subject: 330

description: Purpose: Transaction cost economics sees a broad spectrum of governance structures spanned by two types of economic adaptation: autonomous and cooperative. Stakeholder theorists have drawn much inspiration from transaction cost economics but have not paid explicit attention to the centrality of the idea of adaptation in this literature. This study aims to address this gap. Design/methodology/approach: The authors develop a novel conceptual framework applying the distinction between the two types of economic adaptation to stakeholder theory. Findings: The authors argue that the idea of cooperative adaptation is particularly useful for describing the firm’s collaboration with primary stakeholders in the joint value creation process. In contrast, autonomous adaptation is more relevant for firms interacting with secondary stakeholders who are not directly engaged in joint value creation and may not have formal contractual relationships with the firm. Accordingly, cooperative adaptation can be seen as vital for resolving team production problems affecting joint value creation, whereas autonomous adaptation addresses how the firm maintains legitimacy within the larger stakeholder environment. Originality/value: Similar to its significance for transaction cost economics, the distinction between the two types of adaptation equips stakeholder theory with a new systematic understanding of a potentially broad spectrum of firm–stakeholder collaboration forms.

description: We present deep optical observations of the gravitational lens system CLASS B0218+357, from which we derive an estimate of the Hubble constant. Extensive radio observations have reduced the degeneracies between Hubble's constant and the mass model in this lens to one involving only the position of the radio-quiet lensing galaxy relative to the lensed images. B0218+357 has an image separation of only 334 mas, so optical observations have previously been unable to resolve the lens galaxy from the bright lensed images. Using the new Advanced Camera for Surveys installed on the Hubble Space Telescope, we have measured the separation between the lens galaxy centre and the brightest image. The position found, and hence our estimate of Hubble's constant, depends on our approach to the spiral arms in B0218+357. If the most prominent arms are left unmasked, we find a value for Hubble's constant of 70+/-5 km/s /Mpc (95% confidence). If the spiral arms are masked out, we find a value of 61+/-7 km/s /Mpc (95% confidence).

description: Objectives: Increased levels of glial fibrillary acidic protein (GFAP) in blood have been identified as a valuable biomarker for some neurological disorders, such as Alzheimer’s disease and multiple sclerosis. However, most blood GFAP quantifications so far were performed using the same bead-based assay, and to date a routine clinical application is lacking. Methods: In this study, we validated a novel second-generation (2nd gen) Ella assay to quantify serum GFAP. Furthermore, we compared its performance with a bead-based single molecule array (Simoa) and a homemade GFAP assay in a clinical cohort of neurological diseases, including 210 patients. Results: Validation experiments resulted in an intra-assay variation of 10 %, an inter-assay of 12 %, a limit of detection of 0.9 pg/mL, a lower limit of quantification of 2.8 pg/mL, and less than 20 % variation in serum samples exposed to up to five freeze-thaw cycles, 120 h at 4 °C and room temperature. Measurement of the clinical cohort using all assays revealed the same pattern of GFAP distribution in the different diagnostic groups. Moreover, we observed a strong correlation between the 2nd gen Ella and Simoa (r=0.91 (95 % CI: 0.88–0.93), p<0.0001) and the homemade immunoassay (r=0.77 (95 % CI: 0.70–0.82), p<0.0001). Conclusions: Our results demonstrate a high reliability, precision and reproducibility of the 2nd gen Ella assay. Although a higher assay sensitivity for Simoa was observed, the new microfluidic assay might have the potential to be used for GFAP analysis in daily clinical workups due to its robustness and ease of use.

description: We study the transition at T=0 from a ferromagnetic insulating to a ferromagnetic metallic phase in manganites as a function of hole doping using an effective low-energy model Hamiltonian proposed by us recently. The model incorporates the quantum nature of the dynamic Jahn-Teller(JT) phonons strongly coupled to orbitally degenerate electrons as well as strong Coulomb correlation effects and leads naturally to the coexistence of localized (JT polaronic) and band-like electronic states. We study the insulator-metal transition as a function of doping as well as of the correlation strength U and JT gain in energy E_{JT}, and find, for realistic values of parameters, a ground state phase diagram in agreement with experiments. We also discuss how several other features of manganites as well as differences in behaviour among manganites can be understood in terms of our model.

Casimir effect in polymer scalar field theory

description: In this paper, we study the Casimir effect in the classical geometry of two parallel conducting plates, separated by a distance $L$, due to the presence of a minimal length $λ$ arising from a background independent (polymer) quantization scheme. To this end, we polymer-quantize the classical Klein-Gordon Hamiltonian for a massive scalar field confined between the plates and obtain the energy spectrum. The minimal length scale of the theory introduces a natural cutoff for the momenta in the plane parallel to the plates and a maximum number of discrete modes between the plates. The zero-point energy is calculated by summing over the modes, and by assuming $λ\ll L$, we expressed it as an expansion in powers of $1/N$, being $N=L/ λ$ the number of points between the plates. Closed analytical expressions are obtained for the Casimir energy in the cases of small and large scalar mass limits.

Placing animals in the Plantationocene : the plantation after/lives of nutria in Eastern Germany

description: Nutria (Myocastor coypus), also known as coypu or ‘river rats’, are big semi-aquatic rodents that originate from South America and were shipped to Europe for fur production in the late 1800s. Today, the animals live in wild populations in many places around the globe. One of these places is the Eastern German city of Halle is where they have been able to establish themselves in large populations along the river Saale. This article situates the history and presence of nutria in Eastern Germany in the Plantationocene. The Plantationocene concept regards the plantation as a structuring feature of our present. In the plantation, humans and nonhumans are separated, hierarchically ordered and exploited along different power axes, so that standardised, scalable production becomes possible. In this sense, we argue that the nutria farms of the German Democratic Republic (GDR) followed plantation logics that resembled that of ‘actual’ plantations and that exploited their forced animal labour for fur production. With German reunification, however, nutria lost their economic value and, in many cases, were simply released to save on ‘disposal costs’. Outside the nutria farms, they developed plantation afterlives, where similar logics continued to exert violence on their bodies, such as in their recent classification as ‘invasive alien species’, but were also challenged in a number of ways. Taking cue from recent discussions on the Plantationocene, this article can be considered as an intervention and invitation to move beyond the plantation in the literal sense of the term, so as to study how the Plantationocene works across different species, spaces and times, while being attentive to its limitations.

description: We present results on the physical states of three high-redshift powerful radio galaxies (3C 292 at z=0.7, 3C 184 at z=1, and 3C322 at z=1.7). They were obtained by combining radio measurements with X-ray measurements from XMM-Newton that separate spectrally and/or spatially radio-related and hot-gas X-ray emission. Originally observed as part of a programme to trace clusters of galaxies at high redshift, none of the sources is found to lie in a rich X-ray-emitting environment similar to those of some powerful radio galaxies at low redshift, although the estimated gas pressures are sufficient to confine the radio lobes. The weak gas emission is a particularly interesting result for 3C 184, where a gravitational arc is seen, suggesting the presence of a very massive cluster. Here Chandra data complement the XMM-Newton measurements in spatially separating X-ray extended emission from that associated with the nucleus and rather small radio source. 3C 292 is the source for which the X-ray-emitting gas is measured with the greatest accuracy, and its temperature of 2 keV and luminosity of 6.5E43 erg/s are both characteristic of a poor cluster. This source allows the most accurate measurement of inverse-Compton X-ray emission associated with the radio lobes. In all structures where the magnetic-field strength can be estimated through combining measurements of radio-synchrotron and inverse-Compton-X-ray emission, the field strengths are consistent with sources being in a state of minimum total energy.

One problem, the large cosmological constant needed for inflation, is interpreted by starting with the parameters allowing only the dS vacuum, and the vanishing cosmological constant at a true vacuum is realized by changing parameters by exit from inflation at the brane such that the self-tuning solution is allowed.

description: When a noisy communication channel is used multiple times, the errors occurring at different times generally exhibit correlations. Classically, these correlations do not affect the evolution of individual particles: a single classical particle can only traverse the channel at a definite moment of time, and its evolution is insensitive to the correlations between subsequent uses of the channel. In stark contrast, here we show that a single quantum particle can sense the correlations between multiple uses of a channel at different moments of time. In an extreme example, we show that a channel that outputs white noise when the particle is sent at a definite time can exhibit correlations that enable a perfect transmission of classical bits when the particle is sent at a superposition of two times. In contrast, we show that, in the lack of correlations, a single particle sent at a superposition of two times undergoes an effective channel with classical capacity of at most 0.16 bits. When multiple transmission lines are available, time correlations can be used to simulate the application of quantum channels in a coherent superposition of alternative causal orders, and even to provide communication advantages that are not accessible through the superposition of causal orders.

description: The chaotic inflationary model of the early universe, proposed by Linde is explored in the brane world considering matter described by a minimally coupled self interacting scalar field. We obtain cosmological solutions which admit evolution of a universe either from a singularity or without a singularity. It is found that a very weakly coupled self-interacting scalar field is necessary for a quartic type potential in the brane world model compared to that necessary in general relativity. In the brane world sufficient inflation may be obtained even with an initial scalar field having value less than the Planck scale. It is found that if the universe is kinetic energy dominated to begin with, it transits to an inflationary stage subsequently.

Electrically charged Andreev modes in two-dimensional tilted Dirac cone systems

description: In a graphene-based Josephson junction, the Andreev reflection can become specular which gives rise to propagating Andreev modes. These propagating Andreev modes are essentially charge neutral and therefore they transfer energy but not electric charge. One main result of this work is that when the Dirac theory of graphene is deformed into a tilted Dirac cone, the breaking of charge conjugation symmetry of the Dirac equation renders the resulting Andreev modes electrically charged. We calculate an otherwise zero charge conductance arising solely from the tilt parameters $\vecζ=(ζ_x,ζ_y)$. The distinguishing feature of such a form of charge transport from the charge transport caused by normal electrons is their dependence on the phase difference $ϕ$ of the two superconductors which can be experimentally extracted by employing a flux bias. Another result concerns the enhancement of Josephson current in a regime where instead of propagating Andreev modes, localized Andreev levels are formed. In this regime, we find enhancement by orders of magnitude of the Josephson current when the tilt parameter is brought closer and closer to $ζ=1$ limit. We elucidate that, the enhancement is due to a combination of two effects: (i) enhancement of number of transmission channels by flattening of the band upon tilting to $ζ\approx 1$, and (ii) a non-trivial dependence on the angle $θ$ of the the tilt vector $\vecζ$.

description: This paper uses numerical simulations to test the formation time distribution of dark matter haloes predicted by the analytic excursion set approaches. The formation time distribution is closely linked to the conditional mass function and this test is therefore an indirect probe of this distribution. The excursion set models tested are the extended Press-Schechter (EPS) model, the ellipsoidal collapse (EC) model, and the non-spherical collapse boundary (NCB) model. Three sets of simulations (6 realizations) have been used to investigate the halo formation time distribution for halo masses ranging from dwarf-galaxy like haloes ($M=10^{-3} M_*$, where $M_*$ is the characteristic non-linear mass scale) to massive haloes of $M=8.7 M_*$. None of the models can match the simulation results at both high and low redshift. In particular, dark matter haloes formed generally earlier in our simulations than predicted by the EPS model. This discrepancy might help explain why semi-analytic models of galaxy formation, based on EPS merger trees, under-predict the number of high redshift galaxies compared with recent observations.

En este trabajo se evaluó la influencia de variables a escala local y de paisaje sobre la diversidad beta de las comunidades de peces y los fenómenos de anidamiento y remplazamiento en la cuenca del río Garagoa. Se muestrearon 36 sitios con transectos de 100 m, donde se realizó la colecta de peces, y se registraron variables locales (oxígeno disuelto, pH, conductividad, temperatura, dureza, morfometría del canal, velocidad del agua, caudal y el índice de calidad de la vegetación de ribera QBR-And). Se obtuvieron variables a escala de paisaje (usos del suelo, características geomorfológicas y bioclimáticas) a partir de información secundaria. Se calculó la diversidad beta y se evaluó la influencia de las variables locales y de paisaje sobre este componente, usando Análisis de Componentes Principales (PCA) y Análisis de Redundancia Basada en Distancias (dbRDA). Se registraron 22 especies de peces y una alta diversidad beta explicada principalmente por el remplazamiento de especies. Este componente se vio afectado por una combinación de variables de las dos escalas evaluadas.

description: Machine learning algorithms have been extensively exploited in energy research, due to their flexibility, automation and ability to handle big data. Among the most prominent machine learning algorithms are the boosting ones, which are known to be "garnering wisdom from a council of fools", thereby transforming weak learners to strong learners. Boosting algorithms are characterized by both high flexibility and high interpretability. The latter property is the result of recent developments by the statistical community. In this work, we provide understanding on the properties of boosting algorithms to facilitate a better exploitation of their strengths in energy research. In this respect, (a) we summarize recent advances on boosting algorithms, (b) we review relevant applications in energy research with those focusing on renewable energy (in particular those focusing on wind energy and solar energy) consisting a significant portion of the total ones, and (c) we describe how boosting algorithms are implemented and how their use is related to their properties. We show that boosting has been underexploited so far, while great advances in the energy field are possible both in terms of explanation and interpretation, and in terms of predictive performance.

description: Tropical forests are being reduced by human activities. The use of fire for agricultural expansion generates areas dominated by the bracken fern Pteridium, where forest regeneration is slow. This may be caused by seed limitation, especially of animal-dispersed seeds, due to the absence of seed dispersers from the forest in deforested areas, calling for restoration strategies to assist forest regeneration. We installed bird perches and artificial bat roosts to evaluate their effect on the density, species richness, and composition of animal-dispersed seeds and seedlings of tree and non-tree species in bracken-dominated areas in the tropical montane forest of Bolivia. We found that perches and bat roosts increased the density and species richness of animal-dispersed seeds and established seedlings. The seeds and seedlings dispersed by birds were clumped under the perches, while the seeds and seedlings dispersed by bats were distributed around the roosts. Perches had a higher density and species richness of seeds and seedlings compared to bat roosts, suggesting that the use of perches could be a better option as a restoration tool in bracken-dominated areas. The increase in seed rain and seedling establishment of animal-dispersed species in perches and bat roosts supports seed limitation, hindering forest succession in bracken-dominated areas. The use of bird perches accompanying other restoration techniques is a promising restoration strategy to accelerate forest regeneration in tropical areas dominated by Pteridium, which are widely distributed.

description: We compare the structures of the theory of causal fermion systems (CFS), an
approach to unify quantum theory with general relativity (GR), with those of
modified measure theories (MMT), which are a set of modified gravity theories.
Classical spacetimes with MMT can be obtained as the continuum limit
of a CFS. This suggests that MMT could serve as effective descriptions of
modifications to GR implied by CFS. The goal is to lay the foundation for
future research on exploring which MMTs are consistent with the causal action
principle of CFS.

description: For accurate modelling of groundwater flow and transport processes within an aquifer, precise knowledge about hydraulic conductivity K and its small-scale heterogeneities is fundamental. Methods based on pumping tests, such as hydraulic tomography (HT), allow for retrieving reliable K-estimates, but are limited in their ability to image structural features with high resolution, since the data from time-consuming hydraulic tests are commonly sparse. In contrast, geophysical methods like induced polarization (IP) can potentially yield structural images of much higher resolution, but depend on empirical petrophysical laws that may introduce significant uncertainties to the K-estimation. Therefore, this paper presents a joint inversion procedure for both HT and IP data, which allows for combining the complementary abilities of both methods. Within this approach, a traveltime inversion is applied to the HT data, while the IP inversion is based on a full-decay time-domain forward response, as well as a reparametrization of the Cole–Cole model to invert for K directly. The joint inversion is tested on a synthetic model mimicking horizontally layered sediments, and the results are compared with the individual HT and IP inversions. It is shown that jointly inverting both data sets consistently improves the results by combining the complementary sensitivities of the two methods, and that the inversion is more robust against changes in the experimental setups. Furthermore, we illustrate how a joint inversion approach can correct biases within the petrophysical laws by including reliable K-information from hydraulic tests and still preserving the high-resolution structural information from IP. The different inversion results are compared based on the structural similarity index (SSIM), which underlines the robustness of the joint inversion compared to using the data individually. Hence, the combined application of HT and IP within field surveys and a subsequent joint inversion of both data sets may improve our understanding of hydraulically relevant subsurface structures, and thus the reliability of groundwater modelling results.

description: The proposed Beam Dump Facility (BDF) is foreseen to be located at the North Area of the SPS. It is designed to be able to serve both beam dump like and fixed target experiments. The SPS and the new facility would offer unique possibilities to enter a new era of exploration at the intensity frontier. Possible options include searches for very weakly interacting particles predicted by Hidden Sector models, and flavour physics measurements. In the first instance, exploitation of the facility, in beam dump mode, is envisaged to be for the Search for Hidden Particle (SHiP) experiment. Following the first evaluation of the BDF in 2014-2016, CERN management launched a Comprehensive Design Study over three years for the facility. The BDF study team has since executed an in-depth feasibility study of proton delivery to target, the target complex, and the underground experimental area, including prototyping of key sub-systems and evaluations of the radiological aspects and safety. A first iteration of detailed integration and civil engineering studies have been performed in order to produce a realistic schedule and cost. This document gives a detailed overview of the proposed facility together with the results of the studies, and draws up a possible road map for a three-year Technical Design Report phase, followed by a 5 to 6 year construction phase.

Comparison of the Lived Experiences of Food Insecurity and Food Choices Among Adults Who Currently Smoke versus Formerly Smoked: A Qualitative Investigation
Creators: name: Peterson, Emmaline
Publisher: name: Georgia State University
Year: 2023

description:
Objective: To describe and compare the lived experiences of food insecurity, including the food choices, of people who currently smoke and people who formerly smoked in rural communities.


Design: Secondary analysis of qualitative in-depth interviews.


Participants: N = 32 food insecure participants of which 23 currently smoke and nine formerly smoked in rural Massachusetts.


Analysis: Participants' demographic data were analyzed using t-tests for continuous variables and chi square tests for categorical variables in SPSS. We used Braun & Clarke reflexive thematic analysis and coded the data using NVivo after two coders collaboratively developed a codebook. We evaluated responses from food insecure participants choice to use $10 towards a sandwich or cigarettes. Lastly, we created word clouds to describe participants' food and beverage choices during the previous day and the food and beverage choices from grocery stores and/or free food and meal services.


Results: On average, participants were 44 years old, primarily female (71.9%), and nonHispanic white (62.5%). A total of 7 themes represented the lived experiences of food insecurity among people who currently smoke and formerly smoked. Three themes were specific to participants who currently smoke: A.1) Using Cigarettes to Replace Food in the Context of Food Insecurity, A.2) Buying Cigarettes Instead of Food, Other Necessities, or Entertainment, and A.3) Concerns of Weight Gain Impeding Smoking Cessation. Four themes were seen among participants who currently smoke and formerly smoked B.1) The Interplay of Mental and Physical Illness, Food Insecurity, and Smoking Histories, B.2) Psychosocial Stressors, Health Issues, and Financial Strain Forming a Cycle that Exacerbates Food Insecurity, B.3) Navigating Low-Cost Food Access As a Part of Experiencing Food Insecurity B.4) Showing Resilience Through Food Insecurity Coping Strategies. Food choices were similar among participants who currently smoke and participants who formerly smoked, including a mix of nutrient-dense and high-fat and processed foods. The responses to the hypothetical scenario varied; most people chose a sandwich (47.8%).


Conclusions: On comparing the lived experiences of food insecurity, including food choice, of participants who currently smoke and formerly smoked, we found that participants with a few exceptions mostly shared a multitude of complex challenges and employed various coping strategies to address both food insecurity and their various life adversities and had similar food choices. Future research could describe and compare the lived experiences of food insecurity among participants who currently smoke, formerly smoked, and never smoked in both urban and rural settings.

description: To investigate whether salvianolic acid B is able to enhance repair of degenerated intervertebral discs by mesenchymal stem cells (MSCs) through the promotion of MSC differentiation into nucleus pulposus cells in a nucleus-pulposus-like environment and by enhancing the trophic effect of MSCs on residual nucleus pulposus cells (mediated by transforming growth factor-β1). Successful intervertebral disc degeneration models, established by aspiration of the nucleus pulposus in New Zealand white rabbits, were randomly divided into eight groups: Group A was treated with MSC transplantation. Group B was treated with MSC transplantation and salvianolic acid B, with the subgroups B1, B2, B3, and B4 receiving 0.01 mg/L, 0.1 mg/L, 1 mg/L, and 10 mg/L salvianolic acid B, respectively. Groups C and D were treated with phosphate buffer saline and sham graft, respectively. Group E was the normal control group. At the end of week 8, the type II collagen, proteoglycan, transforming growth factor-β1, and water contents in each group were examined by semi-quantitative immunohistochemistry, spectrophotometry, enzyme-linked immunosorbent assay, and magnetic resonance, respectively. The content of type II collagen, proteoglycan, transforming growth factor-β1, and water in groups B3 and B4 were significantly higher than those in group A (p < 0.01). Salvianolic acid B (1 mg/L to 10 mg/L) plus MSC transplantation was more effective in repairing degenerated intervertebral discs than was stem cell transplantation alone.
