The Dynastinae of the island of Saba, Dutch Caribbean (Coleoptera: Scarabaeidae)
The fauna of Dynastinae (Scarabaeidae) on the island of Saba, Dutch Caribbean, was investigated through fi eldwork during 2006 to 2015. Three species, belonging to the three tribes Cyclocephalini, Pentodontini and Phileurini, are newly recorded from Saba and are discussed, with summaries of all relevant information from the West Indies. Detailed locality data, temporal distributions, and habitus photographs are presented for each species
Diversity and distribution of the scarab beetle tribe Phanaeini in the northern states of the Brazilian Northeast (Coleoptera: Scarabaeidae: Scarabaeinae)
The fauna of Phanaeini of the northeast of Brazil was investigated through fieldwork in the States of Ceará, Maranhão and Piauí, and through study of preserved material from other states. Seven species of Phanaeini are newly recorded from these three states. Of these, two species are also new records for the northeast region: Phanaeus melibaeus Blanchard and an unidentified Dendropaemon Perty species. A total of 13 new state records are given for eight of the 15 species of Phanaeini recorded from the northeast to date, including three new state genus records. A key is provided for identification of all species. Detailed distributional information is presented together with habitat and bait preferences and other ecological data for each species. The diversity and distribution of the tribe in the northeast is discussed in the context of regional biotopes and wider geographic ranges. The fauna is shown to be more diverse than previously believed, containing both endemic and widespread elements occurring in species assemblages that differ according to habitat type and elevation, leading to substantial complementarity of diversity amongst the main biogeographic provinces and biotopes of the region. A fauna de Phanaeini do Nordeste brasileiro é sumarizada, como resultado de novas coletas nos estados do Ceará, Maranhão e Piauí, e pelo estudo de material preservado de outros estados. Sete espécies de Phanaeini são reportadas pela primeira vez para esses estados. Destas, duas espécies são também novos registros para a Região Nordeste: Phanaeus melibaeus Blanchard e uma espécie não identificada de Dendropaemon Perty. Um total de treze novos registros de estatais é apresentado para oito das quinze espécies de Phanaeini reportadas do Nordeste até agora, incluindo treis novos registros estatais de gêneros. Uma chave é dada para permitir a identificação de todas as espécies. Apresenta-se informação detalhada de distribuição, hábitat e preferências por isca e outros dados ecológicos para cada espécie. A diversidade e a distribuição da tribo no Nordeste são discutidas no contexto de biótopos regionais e áreas geográficas maiores. A fauna é considerada mais diversa do que previamente esperado, contendo tanto elementos endêmicos como de ampla distribuição, ocorrendo em assembléias de espécies que variam de acordo com tipos de hábitat e altitude, levando a grande complementariedade da diversidade entre as principais províncias biogeográficas e biótopos da região

The crisis of patient-physician trust and bioethics: lessons and inspirations from China
Trust is indispensable not only for interpersonal relationships and social life, but for good quality healthcare. As manifested in the increasing violence and tension in patient-physician relationships, China has been experiencing a widespread and profound crisis of patient–physician trust. And globally, the crisis of trust is an issue that every society, either developing or developed, has to face in one way or another. Yet, in spite of some pioneering works, the subject of patient-physician trust and mistrust – a crucial matter in healthcare especially because there are numerous ethical implications – has largely been marginalized in bioethics as a global discourse. Drawing lessons as well as inspirations from China, this paper demonstrates the necessity of a trust-oriented bioethics and presents some key theoretical, methodological and philosophical elements of such a bioethics. A trust-oriented bioethics moves beyond the current dominant bioethical paradigms through putting the subject of trust and mistrust in the central agenda of the field, learning from the social sciences, and reviving indigenous moral resources. In order for global bioethics to claim its relevance to the things that truly matter in social life and healthcare, trust should be as vital as such central norms like autonomy and justice and can serve as a potent theoretical framework
Formation of Long-Lived Color Centers for Broadband Visible Light Emission in Low-Dimensional Layered Perovskites.
We investigate the origin of the broadband visible emission in layered hybrid lead-halide perovskites and its connection with structural and photophysical properties. We study ⟨001⟩ oriented thin films of hexylammonium (HA) lead iodide, (C6H16N)2PbI4, and dodecylammonium (DA) lead iodide, (C12H28N)2PbI4, by combining first-principles simulations with time-resolved photoluminescence, steady-state absorption and X-ray diffraction measurements on cooling from 300 to 4 K. Ultrafast transient absorption and photoluminescence measurements are used to track the formation and recombination of emissive states. In addition to the excitonic photoluminescence near the absorption edge, we find a red-shifted, broadband (full-width at half-maximum of about 0.4 eV), emission band below 200 K, similar to emission from ⟨110⟩ oriented bromide 2D perovskites at room temperature. The lifetime of this sub-band-gap emission exceeds that of the excitonic transition by orders of magnitude. We use X-ray diffraction measurements to study the changes in crystal lattice with temperature. We report changes in the octahedral tilt and lattice spacing in both materials, together with a phase change around 200 K in DA2PbI4. DFT simulations of the HA2PbI4 crystal structure indicate that the low-energy emission is due to interstitial iodide and related Frenkel defects. Our results demonstrate that white-light emission is not limited to ⟨110⟩ oriented bromide 2D perovskites but a general property of this class of system, and highlight the importance of defect control for the formation of low-energy emissive sites, which can provide a pathway to design tailored white-light emitters

The Zero Emissions Commitment Model Intercomparison Project (ZECMIP) contribution to C4MIP: Quantifying committed climate changes following zero carbon emissions
The amount of additional future temperature change following a complete cessation of CO2 emissions is a measure of the unrealized warming to which we are committed due to CO2 already emitted to the atmosphere. This “zero emissions commitment” (ZEC) is also an important quantity when estimating the remaining carbon budget – a limit on the total amount of CO2 emissions consistent with limiting global mean temperature at a particular level. In the recent IPCC Special Report on Global Warming of 1.5 ∘C, the carbon budget framework used to calculate the remaining carbon budget for 1.5 ∘C included the assumption that the ZEC due to CO2 emissions is negligible and close to zero. Previous research has shown significant uncertainty even in the sign of the ZEC. To close this knowledge gap, we propose the Zero Emissions Commitment Model Intercomparison Project (ZECMIP), which will quantify the amount of unrealized temperature change that occurs after CO2 emissions cease and investigate the geophysical drivers behind this climate response. Quantitative information on ZEC is a key gap in our knowledge, and one that will not be addressed by currently planned CMIP6 simulations, yet it is crucial for verifying whether carbon budgets need to be adjusted to account for any unrealized temperature change resulting from past CO2 emissions. We request only one top-priority simulation from comprehensive general circulation Earth system models (ESMs) and Earth system models of intermediate complexity (EMICs) – a branch from the 1 % CO2 run with CO2 emissions set to zero at the point of 1000 PgC of total CO2 emissions in the simulation – with the possibility for additional simulations, if resources allow. ZECMIP is part of CMIP6, under joint sponsorship by C4MIP and CDRMIP, with associated experiment names to enable data submissions to the Earth System Grid Federation.

Concerns and expectations in women with polycystic ovary syndrome vary across age and ethnicity: findings from PCOS Pearls Study
ObjectiveTo understand and explore the perceptions and opinions of women with polycystic ovary syndrome (PCOS) and further delineate the variations across age and ethnicity.DesignQualitative survey focussed on lived experiences of people with PCOS. Participants could share their views either as written text or as voice note audio recording(s) on WhatsApp. The data from the audio were transcribed verbatim. Responses were coded by two study members independently, using a thematic inductive method with NVivo 12. Two senior study members then reviewed these codes to identify common themes.SubjectsWomen with PCOS aged 18-60 years.Results43 of 45 participants had a formal diagnosis of PCOS, the remaining two had suspected PCOS which was under investigation. Four participants opted to share their views as voice note recordings. Poor mental health was the most reported (83.3% of participants), followed by dermatological (81.0%) and menstrual issues (76.2%). Participants were generally dissatisfied with the care they received (88.1%). A lengthy diagnostic journey was reported in 35.7% of cases. 52.6% felt less feminine, particularly regarding weight gain and infertility. As part of the recommendations by participants, it was emphasised that others with the condition should educate themselves and be proactive in their management. 46.3% reported that being more enlightened regarding their condition improved their health outcomes and enabled them to advocate for their own care. Women in their 20s expressed distress due to poor mental health, needing a longer time to get the diagnosis, and having weight and eating concerns. While women with PCOS in their 30s discussed their menstrual irregularities and fertility issues, those in their 40s expressed their concerns about the societal expectations of women when diagnosed with PCOS. The concerns varied across ethnicities as well.ConclusionPCOS has wide-ranging consequences for women living with the condition, with many dissatisfied with the clinical support they currently receive. The concerns and expectations vary across ages and ethnicities. Therefore, we propose involving women with PCOS to co-create clinical and educational resources informed by lived experiences to provide end-user-informed services
