Olfactory communication can be of critical importance for mate choice decisions. Lepidoptera are key model systems for understanding olfactory communication, particularly considering sex pheromone signaling in the context of sexual selection. Solvent extraction or rinsing of pheromone-producing structures is a widespread method for quantifying sex pheromones, but such measures reflect what is stor
Background: Intraspecific communication is of crucial importance throughout the animal kingdom and may involve a combination of visual, gustatory, olfactory and acoustic cues. Variation in male sex pheromone amount and composition may convey important information to female conspecifics, for instance on species identity or age. However, whether increased male pheromone titres are associated with fi
Dublon and Sumpter give a concise and access guide to flying insect swarms, some of which, such as the crop-eating locust swarms, are pests, while others, such as honeybee swarms and migrating butterflies, are beneficial.
When acquiring simple three-dimensional (3d) trajectory data it is common to accumulate large coordinate data sets. In order to examine integrity and consistency of object tracking, it is often necessary to rapidly visualise these data. Ordinarily, to achieve this the user must either execute 3d plotting functions in a numerical computing environment or manually inspect data in two dimensions, plo
In a laboratory bioassay, adult female Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) spent more time near filter paper disks that had been exposed to adult males than near unexposed disks; this effect was not observed on disks exposed to adult females. The response could only partly be explained by the known male-produced aggregation pheromone, neryl (S)-2-methylbutanoate, sugges
The aggregation pheromone of the western flower thrips, Frankliniella occidentalis (Thysanoptera: Thripidae), has previously been identified as the monoterpenoid ester neryl (S)-2-methylbutanoate. It attracts both male and female adults to traps in commercial glasshouses. In this paper, we investigate the rates of production of this compound at two male densities and in the presence or absence of
Background: Chronic lung disease (CLD) occurs frequently in preterm infants and is associated with respiratory morbidity. Bronchodilators have the potential effect of dilating small airways with muscle hypertrophy. Increased compliance and tidal volume, and decreased airway resistance, have been documented with the use of bronchodilators in infants with CLD. Therefore, bronchodilators are widely c
Feminist solidarity transcends borders. Yet, there is a tension arising from an entrenched view of feminism as inherently “Western,” originating in Europe and exported to the rest of the world. Building on fieldwork and interviews with Tunisian and Egyptian feminist activists, this paper challenges this perception by looking at how feminist activists relate to their diverging histories, and how fe
Objective: To explore factors associated with change in empowerment in patients that have participated in a 3-month Supported Osteoarthritis Self-Management Program (SOASP). Further, to evaluate empowerment in the longer term. Design: An explorative analysis including patients from a cohort study conducted in primary healthcare in Sweden was performed. Univariable linear regression models were per
Objectives: Patients with SLE have an increased risk of comorbidities and impaired survival. We aimed to assess whether various thresholds of oral CS (OCS) can predict development of infections, comorbidities, malignancies and survival in SLE using data from national health registries in Sweden. Methods: All incident SLE cases, age >18 years, in Sweden (n ¼ 5309) between 2005 and 2020 and matched
This paper builds theory on theatrical cultural design in corporate venturing units, such as manifested in playful esthetics (foosball tables and beanbags), startup lingo, or youthful behavior (building with Lego bricks and informal dressing). We develop a set of propositions, illuminating how theatrical cultural design can (de)legitimize corporate venturing units, highlighting three different fun
Summary: Antiresorptive medications do not negatively affect fracture healing in humans. Teriparatide may decrease time to fracture healing. Romosozumab has not shown a beneficial effect on human fracture healing. Background: Fracture healing is a complex process. Uncertainty exists over the influence of osteoporosis and the medications used to treat it on fracture healing. Methods: Narrative revi
Introduction: Resting heart rate has been distinctly related to both internalizing (high pulse) and externalizing (low pulse) disorders. We aimed to explore the associations between resting heart rate and suicidal behavior (nonfatal suicide attempt [SA] and suicide death [SD]) and evaluate if such associations exist beyond the effects of internalizing/externalizing symptomatology. Method: We used
Humanity’s ever-growing energy demands require the implementation of more sustainable ways to harvest and store energy. At the same time, the reduction of greenhouse gas emission and thus global warming remains of paramount importance. To this end, solar energy harvesting presents an attractive route towards satisfying these requirements—be that by conversion to thermal energy, electricity or to c
INTRODUCTION: To support clinical trial designs focused on early interventions, our study determined reliable early amyloid-β (Aβ) accumulation based on Centiloids (CL) in pre-dementia populations. METHODS: A total of 1032 participants from the Amyloid Imaging to Prevent Alzheimer's Disease–Prognostic and Natural History Study (AMYPAD-PNHS) and Insight46 who underwent [18F]flutemetamol, [18F]florb
A thin (20–80 cm), patchy layer of silt-rich sediment occurs at the surface throughout Svartedalen, a nature reserve 30 km north of Gothenburg, Sweden. This surface silt mantles a bedrock-dominated, fracture-valley landscape. Using data from grain-size analysis, OSL dating and detrital-zircon U-Pb dating, we argue that the silt is loess sourced from glacial sediment that was eroded from local bedr
In order to change consumption patterns into something that is more sustainable, it is essential that we consider the various and conflicting meanings clothes have in people's lives. This article presents an analysis of diaries written by consumers of different ages and occupations over a period of three months in 2015. These consumers documented their clothing and shoe purchases, took inventory o
Background: The molecular content of urine is defined by filtration in the kidneys and by local release from tissues lining the urinary tract. Pathological processes and different therapies change the molecular composition of urine and a variety of markers have been analyzed in patients with bladder cancer. The response to BCG immunotherapy and chemotherapy has been extensively studied and elevate
