description: This paper is concerned with the problem of determining whether a projective-equivalence class of sprays is the geodesic class of a Finsler function. We address both the local and the global aspects of this problem. We present our results entirely in terms of a multiplier, that is, a type (0,2) tensor field along the tangent bundle projection. In the course of the analysis we consider several related issues of interest including the positivity and strong convexity of positively-homogeneous functions, the relation to the so-called Rapcsák conditions, some peculiarities of the two-dimensional case, and geodesic convexity for sprays.

description: We study recently proposed ultraviolet and infrared momentum regulators of the model spaces formed by construction of a variational trial wavefunction which uses a complete set of many-body basis states based upon three-dimensional harmonic oscillator (HO) functions. These model spaces are defined by a truncation of the expansion characterized by a counting number ($\mathcal{N}$) and by the intrinsic scale ($\hbarω$) of the HO basis; in short by the ordered pair ($\mathcal{N},\hbarω$). In this study we choose for $\mathcal{N}$ the truncation parameter $N_{max}$ related to the maximum number of oscillator quanta, above the minimum configuration, kept in the model space. The ultraviolet (uv) momentum cutoff of the continuum is readily mapped onto a defined uv cutoff in this finite model space, but there are two proposed definitions of the infrared (ir) momentum cutoff inherent in a finite-dimensional HO basis. One definition is based upon the lowest momentum difference given by $\hbarω$ itself and the other upon the infrared momentum which corresponds to the maximal radial extent used to encompass the many-body system in coordinate space. Extending both the uv cutoff to infinity and the ir cutoff to zero is prescribed for a converged calculation. We calculate the ground state energy of light nuclei with "bare" and "soft" $NN$ interactions. By doing so, we investigate the behaviors of the uv and ir regulators of model spaces used to describe $^2$H, $^3$H, $^4$He and $^6$He with $NN$ potentials Idaho N$^3$LO and JISP16. We establish practical procedures which utilize these regulators to obtain the extrapolated result from sequences of calculations with model spaces characterized by ($\mathcal{N},\hbarω$).

description: The Mexican Light and Power Company, the Mexico Tramways Company and the Mexico North Western Railway Company were all ventures of James H. Dunn and Dr. F. S. Pearson incorporated in Canada and operating in Mexico during the regime of Porfirio Diaz. These companies were the most important of some eight Canadian companies found in Mexico after the turn of this century. Equally, these Mexican enterprises comprised a large part of a significant Canadian economic expansion into the Caribbean and Latin America at this time that resulted from the growth of the Canadian economy and the prosperity in Canada after 1896. These concerns, however, cannot be characterized as examples of Canadian direct investment abroad. The nature of Canadian economic development with its dependence on both British and American capital inflows led to Canadian specialization in the area of financial intermediation - especially underwriting, promoting and brokerage functions. The Mexican Light and Power Company, the Mexico Tramways Company and the Mexico North Western Railway Company were incorporated in Canada to take advantage of relatively lax laws regulating the activities of companies that guaranteed their activities would take place outside of the Dominion of Canada and Canadian participation was limited to financing these enterprises. Through manipulative selling syndicates organized by James H. Dunn the securities of these ventures were sold to the investing public of Britain, continental Europe and the United States. That Mexico should be the site of three of the largest of these Canadian enterprises abroad was not an accident. Porfirio Diaz provided the essential ingredient of internal stability and granted the companies lucrative and long term concessions, often in perpetuity. While prospering under the Porfiriato, as the reign of Dfaz has come to be called, the excesses of the regime resulted in its collapse in 1911 and by 1915 the three companies of Pearson and Dunn had been placed into receivership, one the victim of revolutionary violence and the others the victims of the chronic instability and also the demand for political and economic sovereignty on the part of the Mexican people.

eDisk Modeling of a Protostellar Disk: Dust Flaring, Viscous Accretion Heating, and Larger Gas Radius

description: We conducted radiative transfer modeling and ALMA observing simulations to reproduce the 1.3-mm dust-continuum and C18O (2-1) images toward the Class I protostar R Cr A IRS7B observed with the ALMA Large Program, Early Planet Formation in Embedded Disks (eDisk). We found that the observed high brightness temperature of the 1.3-mm dust-continuum emission (~195 K) cannot be reproduced by only the passing heating from the central protostar. Viscous accretion heating in the disk is required to realize such a high dust brightness temperature. In other words, the protostellar disk is self-luminous. Furthermore, the observed skewed distribution of the dust emission along the disk minor axis is due to the flaring of the dust coupled with the optically thick dust emission. We also found that the radius of the gas disk (~80 au) as traced by the C18O (2-1) emission should be larger than that of the dust disk (~60 au). These results of a protostellar disk is in sharp contrast to those of protoplanetary disks around Class II sources.

description: Monolayer δ-doped structures in silicon have attracted renewed interest with their recent incorporation into atomic-scale device fabrication strategies as source and drain electrodes and in-plane gates. Modeling the physics of δ-doping at this scale proves challenging, however, due to the large computational overhead associated with ab initio and atomistic methods. Here, we develop an analytical theory based on an effective mass approximation. We specifically consider the Si:P materials system, and the limit of high donor density, which has been the subject of recent experiments. In this case, metallic behavior including screening tends to smooth out the local disorder potential associated with random dopant placement. While smooth potentials may be difficult to incorporate into microscopic, single-electron analyses, the problem is easily treated in the effective mass theory by means of a jellium approximation for the ionic charge. We then go beyond the analytic model, incorporating exchange and correlation effects within a simple numerical model. We argue that such an approach is appropriate for describing realistic, high-density, highly disordered devices, providing results comparable to density functional theory, but with greater intuitive appeal, and lower computational effort. We investigate valley coupling in these structures, finding that valley splitting in the low-lying Γband grows much more quickly than the Γ-Δband splitting at high densities. We also find that many-body exchange and correlation corrections affect the valley splitting more strongly than they affect the band splitting.

Establishing human connections: experimental evidence from the helping game
Creators: name: Al Lily, Miriam
Publisher: name: American University of Bahrain
Year: 2023
Subjects: classificationCode: 38
subject: Economics

description: This article studies human connections by examining the helping game—a hybrid between the classic two-player and multi-player prisoner’s dilemma. In the helping game, players are presented with a pool of heterogeneous players and have to decide whom to help, if any. Helping others is associated with a cost unique to each potential partner, and receiving help is associated with a fixed benefit. An economic experiment was conducted with 100 students to analyse under which circumstances partnerships (defined as both helping each other) develop in the game. The findings indicate that partnerships form in the game, although mainly when providing help is relatively cheap for both parties. Therefore, most partnerships are between lower helping-cost players, while higher helping-cost players struggle to form partnerships. In addition, establishing partnerships is easier when players meet potential partners consecutively rather than simultaneously, as long as helping others is not too costly. Moreover, less risk-tolerant subjects provide more help to reduce the risk of not forming partnerships, yet establish fewer partnerships, as less risk-tolerant players avoid helping others when it is costly.

description: Das Ziel der vorliegenden Arbeit ist die Verknüpfung von individueller Innovationskompetenz und Problem-based-learning im hochschulischen Kontext unter besonderer Betrachtung der hochschulischen Pflegebildung. Ein erster Fokus liegt dabei auf der Innovationskompetenz. Dabei handelt es sich um eine Fähigkeit, die heute auf dem Arbeitsmarkt, nicht nur im Gesundheitssektor, sondern in allen Bereichen gefordert wird. Dies bietet Anlass zur genaueren inhaltlichen Auseinandersetzung. Diese Arbeit eruiert zunächst die Persönlichkeitsmerkmale, die Einfluss auf die individuelle Innovationskompetenz haben. Daran anschließend stellt sich die Frage nach der optimalen didaktischen Methode, diese Persönlichkeitsmerkmale im Rahmen der Hochschulbildung gezielt zu fördern. Zur Beantwortung dieser Frage legt diese Arbeit einen zweiten Fokus auf die Lehr-/Lernmethode des Problem-based-learning. Mittels einer ausführlichen Literaturrecherche nach dem Schneeballsystem werden beide Themenkomplexe intensiv beleuchtet, bevor im Anschluss daran zwei Studien einander gegenübergestellt werden, die sichtbar machen, welche Anteile von individueller Innovationskompetenz durch Problem-based-learning gefördert werden. Das Ergebnis ist eine deutliche Überschneidung in diversen Aspekten und damit die Erkenntnis, dass Problem-based-learning im hochschulischen Kontext eine effektive Methode ist, um individuelle Innovationskompetenz zu fördern. Der Einsatz von Problem-based-learning in der curricularen Entwicklung der hochschulischen Pflegebildung ist daher zur Innovationskompetenzentwicklung von Studierenden ein valider Ansatz. Weiterführend könnten die Entwicklung und Implementierung eines entsprechenden Curriculums das Ziel anschließender Forschungsarbeiten sein.

description: In the present work, we provide a dielectric study on two differently concentrated aqueous lysozyme solutions in the frequency range from 1 MHz to 40 GHz and for temperatures from 275 to 330 K. We analyze the three dispersion regions, commonly found in protein solutions, usually termed beta-, gamma-, and delta-relaxation. The beta-relaxation, occurring in the frequency range around 10 MHz and the gamma-relaxation around 20 GHz (at room temperature) can be attributed to the rotation of the polar protein molecules in their aqueous medium and the reorientational motion of the free water molecules, respectively. The nature of the delta-relaxation, which often is ascribed to the motion of bound water molecules, is not yet fully understood. Here we provide data on the temperature dependence of the relaxation times and relaxation strengths of all three detected processes and on the dc conductivity arising from ionic charge transport. The temperature dependences of the beta- and gamma-relaxations are closely correlated. We found a significant temperature dependence of the dipole moment of the protein, indicating conformational changes. Moreover we find a breakdown of the Debye-Stokes-Einstein relation in this protein solution, i.e., the dc conductivity is not completely governed by the mobility of the solvent molecules. Instead it seems that the dc conductivity is closely connected to the hydration shell dynamics.

description: Energy-harvesting wireless sensor networking is an emerging technology with applications to various fields such as environmental and structural health monitoring. A distinguishing feature of wireless sensors is the need to perform both source coding tasks, such as measurement and compression, and transmission tasks. It is known that the overall energy consumption for source coding is generally comparable to that of transmission, and that a joint design of the two classes of tasks can lead to relevant performance gains. Moreover, the efficiency of source coding in a sensor network can be potentially improved via distributed techniques by leveraging the fact that signals measured by different nodes are correlated. In this paper, a data gathering protocol for multihop wireless sensor networks with energy harvesting capabilities is studied whereby the sources measured by the sensors are correlated. Both the energy consumptions of source coding and transmission are modeled, and distributed source coding is assumed. The problem of dynamically and jointly optimizing the source coding and transmission strategies is formulated for time-varying channels and sources. The problem consists in the minimization of a cost function of the distortions in the source reconstructions at the sink under queue stability constraints. By adopting perturbation-based Lyapunov techniques, a close-to-optimal online scheme is proposed that has an explicit and controllable trade-off between optimality gap and queue sizes. The role of side information available at the sink is also discussed under the assumption that acquiring the side information entails an energy cost. It is shown that the presence of side information can improve the network performance both in terms of overall network cost function and queue sizes.

description: Regulatory relevance of the EU Research Cluster to understand the health impacts of micro and nano plastics (CUSP)
 Micro- and nanoplastics: substances of public health concern? The presence of micro and nanoplastics (MNPs) is part of our everyday life and they find their way into our bodies through the air we breathe, the water we drink and the food we eat. It is not known how MNPs might be affecting human health. Policymakers and
 regulatory authorities around the world are increasingly implementing regulatory measures
 to address this concern. For instance, policymakers in the EU have adopted the Single-use Plastics Directive to reduce the environmental impact of certain forms of plastics used once or for a very limited period of time, such as straws, cutlery, plates, cotton swabs and balloon sticks1. Early in 2021, the European Commission funded five large-scale research projects under the European Union’s Horizon 2020 research and innovation programme (see figure 1) and united them under the European Research Cluster to Understand the Health Impacts of Micro-and Nanoplastics (CUSP) (see https://cusp-research.eu). In total, CUSP unites a multidisciplinary team of scientists, industries, and policymakers from 75 organisations across 21 countries. The five projects collaborate in understanding exposure routes; in assessment of hazard and risk; in developing new analytical tools, in data-sharing, in inter-laboratory comparisons, and in communicating and disseminating research results. By establishing six CUSP working groups, our synergies seek to amplify the efforts of individual projects. The close collaboration with the European Commission’s Joint Research Centre (JRC) and a constant dialogue between scientists, stakeholders and policymakers will enhance the policy relevance and impact of the research.

description: We present a detailed study of the Circinus Galaxy, investigating its star formation, dust and gas properties both in the inner and outer disk. To achieve this, we obtained high-resolution Spitzer mid-infrared images with the IRAC (3.6, 5.8, 4.5, 8.0 micron) and MIPS (24 and 70 micron) instruments and sensitive HI data from the Australia Telescope Compact Array (ATCA) and the 64-m Parkes telescope. These were supplemented by CO maps from the Swedish-ESO Submillimetre Telescope (SEST). Because Circinus is hidden behind the Galactic Plane, we demonstrate the careful removal of foreground stars as well as large- and small-scale Galactic emission from the Spitzer images. We derive a visual extinction of Av = 2.1 mag from the Spectral Energy Distribution of the Circinus Galaxy and total stellar and gas masses of 9.5 x 10^{10} Msun and 9 x 10^9 Msun, respectively. Using various wavelength calibrations, we find obscured global star formation rates between 3 and 8 Msun yr^{-1}. Star forming regions in the inner spiral arms of Circinus, which are rich in HI, are beautifully unveiled in the Spitzer 8 micron image. The latter is dominated by polycyclic aromatic hydrocarbon (PAH) emission from heated interstellar dust. We find a good correlation between the 8 micron emission in the arms and regions of dense HI gas. The (PAH 8 micron) / 24 micron surface brightness ratio shows significant variations across the disk of Circinus.

description: For the first time in the CERN history two experimental programs devoted to study nucleus-nucleus collisions at high energies are performed in parallel. In the SPS ion program, carried out by NA61/SHINE, interactions of light and medium size ions in the energy range 5-20 GeV are investigated. The program aims to discover the critical point of strongly interacting matter as well as establish properties of the onset of deconfinement. In 2010 ALICE, ATLAS and CMS at LHC recorded first data on Pb+Pb collisions at the highest energy reached up to now, 2760 GeV. This opens a new exciting area in the field of heavy ion collisions. The relation between the two programs is discussed in this presentation. Surprisingly, the first LHC results strongly support the NA49 discovery of the onset of deconfinement and thus further experimental study of nucleus-nucleus collisions at the CERN SPS.

description: Using accurate numerical relativity simulations of (nonspinning) black-hole binaries with mass ratios 1:1, 2:1 and 3:1 we compute the gauge invariant relation between the (reduced) binding energy $E$ and the (reduced) angular momentum $j$ of the system. We show that the relation $E(j)$ is an accurate diagnostic of the dynamics of a black-hole binary in a highly relativistic regime. By comparing the numerical-relativity $E^{\rm NR} (j)$ curve with the predictions of several analytic approximation schemes, we find that, while the usual, non-resummed post-Newtonian-expanded $E^{\rm PN} (j)$ relation exhibits large and growing deviations from $E^{\rm NR} (j)$, the prediction of the effective one-body formalism, based purely on known analytical results (without any calibration to numerical relativity), agrees strikingly well with the numerical-relativity results.

description: We have performed electron energy-loss spectroscopy (EELS) studies of Ni(111), graphene/Ni(111), and the graphene/Au/Ni(111) intercalation-like system at different primary electron energies. A reduced parabolic dispersion of the πplasmon excitation for the graphene/Ni(111) system is observed compared to that for bulk pristine and intercalated graphite and to linear for free graphene, reflecting the strong changes in the electronic structure of graphene on Ni(111) relative to free-standing graphene. We have also found that intercalation of gold underneath a graphene layer on Ni(111) leads to the disappearance of the EELS spectral features which are characteristic of the graphene/Ni(111) interface. At the same time the shift of the πplasmon to the lower loss-energies is observed, indicating the transition of initial system of strongly bonded graphene on Ni(111) to a quasi free-standing-like graphene state.

description: Brain cancers are among the most aggressive malignancies with high mortality and morbidity worldwide. The pathogenesis of brain cancers is a very complicated process involving various genetic mutations affecting several oncogenic signaling pathways like Wnt/β-catenin axis. Uncontrolled activation of this oncogenic signaling is associated with decreased survival rate and poor prognosis in cancer patients. Long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) were shown to play important roles in regulating cell proliferation, differentiation, and apoptosis by regulating the expression of their target genes. Aberrant expression of these non-coding RNAs (ncRNAs) was reported in many human cancers, including glioblastoma, medulloblastoma, meningioma, and pituitary adenoma. Multiple lncRNAs were shown to participate in brain tumor pathogenesis by targeting Wnt signaling regulatory miRNAs. SNHG7/miR-5095, PCAT6/miR-139-3p, SNHG6/miR-944, SNHG1/ miR-556‐5p, SNHG17/ miR-506-3p, LINC00702/miR-4652-3p, DLGAP1-AS1/miR-515-5p, HOTAIR/miR-1, HOTAIR/miR-206, CRNDE/miR-29c-3p, AGAP2-AS1/ miR-15a/b-5p, CLRN1-AS1/miR-217, MEG3/miR-23b-3p, and GAS5/miR-27a-5p are identified lncRNA/miRNA pairs that are involved in this process. Therefore, recognition of the expression profile and regulatory role of ncRNAs on the Wnt signaling may offer a novel approach to the diagnosis, prognosis, and treatment of human cancers. This review summarizes previous data on the modulatory role of lncRNAs/miRNAs on the Wnt/β-catenin pathway implicated in tumor growth, EMT, metastasis, and chemoresistance in brain cancers.

It analyses the divergence between Saudi Arabiaâ€™s PPP rates and the fixed market exchange rate and examines the relationship between Saudi Arabiaâ€™s PPP rates and oil prices, revealing the paradoxical decline in living standards during periods of high oil prices. In conclusion, the PPP exchange rates for Saudi Arabia appear to fail to accurately assess living standards in Saudi Arabia.

Starke vs. schwache Flexion aufeinanderfolgender attributiver Adjektive: mit hohem technischen/technischem Aufwand
Creators: name: Münzberg, Franziska
name: Hansen, Sandra
Publisher: name: Bausteine einer Korpusgrammatik des Deutschen
Year: 2020

description: Usually, weak inflection of an attributive or nominalized adjective occurs if the adjective is preceded by an inflected determiner: mit diesem technischen Aufwand (‘at great technical expense’). Otherwise, the inflection of the adjective is strong: mit technischem Aufwand. Following this rule of thumb, we would expect strong inflection of an adjective following another adjective whenever the determiner is missing: mit hohem technischem Aufwand. But many German speakers opt for a weak dative singular ending -en following the strong ending -em on the first adjective: mit hohem technischen Aufwand. This chapter shows which explanatory variables play a role in this variation within standard German.

description: This paper presents findings of research focused on divestment practices and their implications for product lifespans and the environment. Divestment comprises all the activities that include emotional and physical disposal of material possessions. Using a cross-cultural mixed-methods approach, the study compares purchase and divestment practices across four different consumer profiles. Findings show how behaviour on ethical divestment does not match that on ethical purchasing. It is observed that the divestment practices of the study participants are influenced by factors different from those that are relevant at the acquisition stage. Three main components that shape divestment processes are identified: material and immaterial rewards that can be obtained from divestment activities, contextual factors that outline scenarios for divesting items and individual motivational factors. These findings support the need for considering divestment practices and attitudes when designing a new product, in order to encourage ethical behaviours across the entire product lifespan. By considering these elements, this analysis sets the principles for creating a framework that considers the implications of possessions lifespans and circularity of divested items in the pursuit of more sustainable ways of consumption.

description: The differences in energy between electronic bands due to valley splitting are of paramount importance in interpreting transport spectroscopy experiments on state-of-the-art quantum devices defined by scanning tunneling microscope lithography. We develop a plane-wave density functional theory description of these systems which is size-limited due to computational tractability. We then develop a less resource-intensive alternative via localized basis functions, retaining the physics of the plane-wave description, and extend this model beyond the capability of plane-wave methods to determine the ab initio valley splitting of well-isolated δ-layers. In obtaining agreement between plane-wave and delocalized methods, we show that the valley splitting has been overestimated in previous ab initio calculations by more than 50%.

description: This article reviews some results of the SAGEX programme that have developed in the understanding of the interplay of supersymmetry and modular covariance of scattering amplitudes in type IIB superstring theory and its holographic image in N=4 supersymmetric Yang–Mills theory (SYM). The first section includes the determination of exact expressions for BPS interactions in the low-energy expansion of type IIB superstring amplitudes. The second section concerns properties of a certain class of integrated correlators in N=4 SYM with arbitrary classical gauge group that are exactly determined by supersymmetric localisation. Not only do these reproduce known features of perturbative and non-perturbative N=4 SYM for any classical gauge group, but they have large-N expansions that are in accord with expectations based on the holographic correspondence with superstring theory. The final section focusses on modular graph functions. These are modular functions that are closely associated with coefficients in the low-energy expansion of superstring perturbation theory and have recently received quite a lot of interest in both the physics and mathematics literature.

description: A new three-phase steamflood numerical model has been developed. It is fully implicit with the Jacobian being calculated analytically. The model can operate in one and two dimensions, compositional and noncompositional modes with the choice of block-centered or pointdistributed grid systems employing five-point or nine-point finite difference schemes. Two different approaches have been employed and tested for their ability to remove the effect of grid orientation in steamflood simulation. The nine-point finite difference scheme reduces the grid orientation effects dramatically while the harmonic total mobility scheme is demonstrated to aggravate the problem rather than alleviate it. The applicability of the two-point upstream mobility in steamflood simulation has been investigated. It has been shown that the twopoint upstream mobility weighting may not be valid for thermal process simulators. The results of grid size and time step sensitivity analyses show that the time - pore volume injected relationship is very sensitive to grid size and to a much lesser extent to time step size. Sensitivity studies of grid size and time step are meaningful only if each is carried out while the other variable has been chosen to minimize the truncation error associated with it. The effects of well model, heat loss, and gas hysteresis on performance parameters and primary variables are also presented and discussed. Several side benefits have resulted from this investigation. These are: 1. A novel method of solution has been developed. It offers significant reductions in both storage and computational requirements for problems with large number of grid blocks. 2. A one-problem formulation method has been developed. It involves the introduction of new pseudo physical equilibrium constants. 3. A new implicit injection scheme which takes into account the effect of steam flashing on injectivity has been developed. 4. Equations for the well geometric factor in the well model f or a corner well block have been derived. 5. An analytical solution for the rate of heat loss to the surrounding formations has been developed.

description: We present a new micromechanical resonator designed for cavity optomechanics. We have used a micropillar geometry to obtain a high-frequency mechanical resonance with a low effective mass and a very high quality factor. We have coated a 60-$μ$m diameter low-loss dielectric mirror on top of the pillar and are planning to use this micromirror as part of a high-finesse Fabry-Perot cavity, to laser cool the resonator down to its quantum ground state and to monitor its quantum position fluctuations by quantum-limited optical interferometry.
The Algol System SZ Herculis: Physical Nature and Orbital Behavior

description: Multiband CCD photometric observations of SZ Her were obtained between 2008 February and May. The light curve was completely covered and indicated a significant temperature difference between both components. The light-curve synthesis presented in this paper indicates that the eclipsing binary is a classical Algol-type system with parameters of $q$=0.472, $i$=87$^\circ$.57, and $Δ$($T_{1}$--$T_{2}$)=2,381 K; the primary component fills approximately 77% of its limiting lobe and is slightly larger than the lobe-filling secondary. More than 1,100 times of minimum light spanning more than one century were used to study an orbital behavior of the binary system. It was found that the orbital period of SZ Her has varied due to a combination of two periodic variations with cycle lengths of $P_3$=85.8 yr and $P_4$=42.5 yr and semi-amplitudes of $K_3$=0.013 d and $K_4$=0.007 d, respectively. The most reasonable explanation for them is a pair of light-time effects (LITEs) driven by the possible existence of two M-type companions with minimum masses of $M_3$=0.22 M$_\odot$ and $M_4$=0.19 M$_\odot$, that are located close to the 2:1 mean motion resonance. If two additional bodies exist, then the overall dynamics of the multiple system may provide a significant clue to the formation and evolution of the eclipsing pair.

description: We present a mechanism for the dark matter stability in the framework of a non-Abelian avour symmetry renormalizable model. The same non-abelian discrete avor symmetry which accounts for the observed pattern of neutrino oscillations, spontaneously breaks to a Z2 subgroup which renders DM stable. The simplest scheme leads to a scalar doublet DM potentially detectable in nuclear recoil experiments, inverse neutrino mass hierarchy, hence a neutrinoless double beta decay rate accessible to upcoming searches.
