- There is strong circumstantial evidence that certain heavy, unstable atomic nuclei are 'octupole deformed', that is, distorted into a pear shape. This contrasts with the more prevalent rugby-ball shape of nuclei with reflection-symmetric, quadrupole deformations. The elusive octupole deformed nuclei are of importance for nuclear structure theory, and also in searches for physics beyond the standard model; any measurable electric-dipole moment (a signature of the latter) is expected to be amplified in such nuclei. Here we determine electric octupole transition strengths (a direct measure of octupole correlations) for short-lived isotopes of radon and radium. Coulomb excitation experiments were performed using accelerated beams of heavy, radioactive ions. Our data on Rn-220 and Ra-224 show clear evidence for stronger octupole deformation in the latter. The results enable discrimination between differing theoretical approaches to octupole correlations, and help to constrain suitable candidates for experimental studies of atomic electric-dipole moments that might reveal extensions to the standard model.

- BACKGROUND: Sexual communication is a common target in psychological treatments for vulvodynia, and associations with sexual function and distress, as well as pain intensity, have been demonstrated. However, structured observations of the communication patterns of couples with vulvodynia are lacking, as these are needed to guide treatment efforts.AIM: To explore (1) the sexual communication patterns in couples with vulvodynia in terms of observed communication quality (operationalized as validating and invalidating responses), self-reported sexual assertiveness, and self-disclosure and (2) associations between sexual communication quality and pain intensity.METHODS: In a case-control design with within- and between-group comparisons, 62 couples engaged in videotaped discussions about their sexual relationship. Trained coders assessed the discussions by rating sexual communication (validation and invalidation) according to a structured behavioral coding scheme. Group differences in sexual communication quality were examined with parametric and nonparametric tests. Dyadic associations among observed communication quality, self-rated sexual assertiveness, and self-disclosure were examined within the actor-partner interdependence model. Multiple regression was used to test the predictive value of partners' validation/invalidation on the pain intensity of the women with vulvodynia.OUTCOMES: Observed communication quality (ie, validation and invalidation), self-reported sexual assertiveness, self-disclosure, and pain intensity.RESULTS: Partners of women with vulvodynia were more invalidating toward their partners than those of women without pain. There were no significant differences in validating/invalidating communication between women in the 2 groups or in validation between partners. Partners' validating communication were significantly associated with women's lower pain intensity. The sexual communication patterns differed between couples with and without vulvodynia, and the associations between validating/invalidating responses and sexual assertiveness were stronger in the vulvodynia group than in the group without pain. Results on validation/invalidation and self-disclosure were inconclusive.CLINICAL IMPLICATIONS: The results indicate a need to direct treatment interventions toward couples' sexual communication quality (ie, levels of validation and invalidation).STRENGTHS AND LIMITATIONS: Strengths include systematic behavioral coding and dyadic analyses. Limitations include the cross-sectional design and self-selection of participants.CONCLUSION: This study demonstrated sexual communication patterns specific to couples with vulvodynia, and we conclude that validation and invalidation are important components of the sexual communication of couples with vulvodynia as they relate to sexual assertiveness, women's self-disclosure, and pain intensity.

- Soil texture plays a crucial role in organic matter (OM) mineralization through both direct interactions with minerals and indirect effects on soil moisture. Separating these effects could enhance the modelling of soil organic carbon (SOC) dynamics under climate change scenarios. However, the attempts have been limited small-scale experiments. Here, we studied the effects of soil texture on added OM mineralization in loamy sand, loam and silt loam soils in nine agricultural fields in Flanders, Belgium. Soil moisture, temperature, groundwater table depth and the mineralization of 13C-labeled ryegrass were monitored in buried mesocosms for approximately three months during a dry summer. Ryegrass-C mineralization was lowest in the loamy sand (39 ± 7 %) followed by silt loam (48 ± 7 %) and loam (63 ± 5 %) soils, challenging the current clay%-based moderation of C-mineralization rates in soil models. Soil temperature was not influenced by soil texture, whereas soil moisture was indeed dependent on soil texture. It appears that capillarity sustained upward water supply from groundwater to the topsoil in loam and silt loam soils but not in loamy sand soil, although this difference in capillary rise could not fully explain the higher moisture content in loam than that in silt loam soils. Additionally, soil texture only impacted remnant added ryegrass pieces (>500 μm) but not the finer ryegrass-derived SOC (<500 μm), which might point at the important indirect control of texture on OM mineralization during prolonged summer drought. However, these effects are only manifested during drought when no other factors (e.g., groundwater depth or subsurface water flows) exert an overriding impact on the soil water balance. Overall, our findings highlight the need to properly incorporate the indirect effects of soil texture on OM mineralization into soil carbon models to accurately predict soil C stocks under future climate change scenarios.

System controls of coastal and open ocean oxygen depletion

Forskningsöversikt (refereegranskat)abstract
- The epoch of the Anthropocene, a period during which human activity has been the dominant influence on climate and the environment, has witnessed a decline in oxygen concentrations and an expansion of oxygen-depleted environments in both coastal and open ocean systems since the middle of the 20th century. This paper provides a review of system-specific drivers of low oxygen in a range of case studies representing marine systems in the open ocean, on continental shelves, in enclosed seas and in the coastal environment. Identification of similar and contrasting responses within and across system types and corresponding oxygen regimes is shown to be informative both in understanding and isolating key controlling processes and provides a sound basis for predicting change under anticipated future conditions. Case studies were selected to achieve a balance in system diversity and global coverage. Each case study describes system attributes, including the present-day oxygen environment and known trends in oxygen concentrations over time. Central to each case study is the identification of the physical and biogeochemical processes that determine oxygen concentrations through the tradeoff between ventilation and respiration. Spatial distributions of oxygen and time series of oxygen data provide the opportunity to identify trends in oxygen availability and have allowed various drivers of low oxygen to be distinguished through correlative and causative relationships. Deoxygenation results from a complex interplay of hydrographic and biogeochemical processes and the superposition of these processes, some additive and others subtractive, makes attribution to any particular driver challenging. System-specific models are therefore required to achieve a quantitative understanding of these processes and of the feedbacks between processes at varying scales.
