Respiratory heme A-containing oxidases originated in the ancestors of iron-oxidizing bacteria

Respiration is a major trait shaping the biology of many environments. Cytochrome oxidase containing heme A (COX) is a common terminal oxidase in aerobic bacteria and is the only one in mammalian mitochondria. The synthesis of heme A is catalyzed by heme A synthase (CtaA/Cox15), an enzyme that most likely coevolved with COX. The evolutionary origin of COX in bacteria has remained unknown. Using ex

Is There More to Within-plant Variation in Seed Size than Developmental Noise?

Within-plant variation in seed size may merely reflect developmental instability, or it may be adaptive in facilitating diversifying bet-hedging, that is, production of phenotypically diverse offspring when future environments are unpredictable. To test the latter hypothesis, we analyzed patterns of variation in seed size in 11 populations of the perennial vine Dalechampia scandens grown in a comm

Product lifetime, right to repair, and repair cafes

Achieving a more circular production and consumption pattern will require consumers to make proactive choices regarding practices such as repair and product life extension. However, galvanizing such choices and practices may not be left alone up to consumers because their behaviors are driven not only by internal factors (e.g., attitude and motivation), but also by external (e.g., economic, social

A matter of timing: system requirements for repair and their temporal dimensions

Research into repair within the circular economy (CE) typically focuses on technical aspects of design, policy, and markets, and often assumes or implies simplified conditions for the user/owner and the product-system to explain the barriers to scaling repair activities. By integrating life cycle and temporal dimensions (time-sequence) into a broad System of Repairability framework, we demonstrate

Sex ratios at birth in Australia according to mother's country of birth : A national study of all 5 614 847 reported live births 1997-2016

OBJECTIVES: Son preference and sex selective practices have resulted in a deficit of girls in several countries, primarily across Asia. Emerging evidence indicates that son preference survives migration to Western high-income countries. The objective of this study was to assess male-to-female (M/F) ratios at birth per mother's country of birth in Australia 1997-2016, in total and by parity, and by

The Quest for Economic Stability: A Study on Swedish Stabilization Policies 1873-2019

This paper explores the evolution of Swedish stabilization policies through six policy regimes between 1873 and 2019. We focus on discretionary policy decisions by estimating policy shocks using a SVAR model. Through these shocks, we explore how stabilization policies have evolved over time and how policymakers responded to key economic events such as financial crises and wars.

The Role of Patents and Licensing in the Governance of Human Genome Editing: A White Paper

On 12 July 2021 the World Health Organization (WHO) Expert Advisory Committee on Developing Global Standards for Governance and Oversight of Human Genome Editing published a set of reports entitled Human Genome Editing: A Framework for Governance and Recommendations. These reports provide valuable advice and recommendations on appropriate institutional, national and global governance mechanisms fo

Plasma proenkephalin A 119-159 on intensive care unit admission is a predictor of organ failure and 30-day mortality

BACKGROUND: Proenkephalin A 119-159 (penKid) has been suggested as a marker of renal failure and poor outcome. We aimed to investigate the association of penKid on ICU admission with organ dysfunction and mortality in a mixed ICU population. In this retrospective, observational study, admission penKid levels from prospectively collected blood samples of consecutive patients admitted to four Swedis

Stereotype Content at the Intersection of Gender and Sexual Orientation

According to the Stereotype Content Model (SCM), the content of stereotypes differs on two dimensions: communion and agency. Research shows that for stereotypes about the general gender categories of “women” and “men,” there is an ambivalent pattern of communion and agency, where high levels on one dimension are associated with low levels on the other. For sexual minority stereotypes, a gender inv

Dispersal and spatiotemporal distribution of Protapion fulvipes in white clover fields : implications for pest management

Yield loss caused by insect pests remains a substantial problem in agriculture. Chemical control, with potential negative effects on non-target organisms, is still the main tool for pest management. For pest species with limited dispersal capacity, rotation of the crop in time and space has potential as an alternative management measure. This is particularly important in organic farming, where mos

Towards Fully Pipelined Decoding of Spatially Coupled Serially Concatenated Codes

Having close-to-capacity performance and low error floor, even for small block lengths, make spatially coupled serially concatenated codes (SC-SCCs) a very promising class of codes. However, classical window decoding of SC-SCCs either limits the minimum block length or requires a large number of iterations, which increases the complexity and constrains the degree to which an SC-SCC decoder archite

Investigation on residual stress evolution in nickel-based alloy affected by multiple cutting operations

Machining-induced residual stresses in a part can significantly influence its performance and service time. It is common that the final surface of the part is produced after multiple cuts in the machining process. In multiple cuts, the previous cuts could often generate accumulated strain/stress and temperature on the part surface. These accumulated strain/stress and temperature will be brought to

Metabolic factors and the risk of Dupuytren’s disease : data from 30,000 individuals followed for over 20 years

Dupuytren’s disease (DD) is a fibroproliferative disorder affecting the palmar fascia of the hand. Risk factors include diabetes mellitus (DM), whereas a high body mass index (BMI) is associated with a lower prevalence of DD. The aim of this study was to further elucidate risk and protective factors for the development of DD using longitudinal population-based data from the Malmö Diet and Cancer S
