Hybrid cauliflower production predominately relies on pollen transfer from hermaphrodite to female lines by honeybees. However, the presence of other pollinators may impact pollination success. Here, we investigate how honeybee visitation frequency and behaviour vary with plant sex and presence of blowflies and affect seed and pod set. We found substantial pollen limitation when honeybees were alo

Grazing can have considerable ecological impacts when managed inappropriately, however livestock production is a significant contributor to global food security and the removal of land from production is not always a viable option. Grazing management practices that incorporate periods of planned rest (i.e. strategic-rest grazing) may be an alternative to grazing exclusion or continuous grazing tha

Body size is an integral functional trait that underlies pollination-related ecological processes, yet it is often impractical to measure directly. Allometric scaling laws have been used to overcome this problem. However, most existing models rely upon small sample sizes, geographically restricted sampling and have limited applicability for non-bee taxa. Allometric models that consider biogeograph

Parasitoid wasps (Hymenoptera) are a highly diverse component of terrestrial habitats, yet very little is known about how their community structure and functional diversity is influenced by habitat variables. Parasitoids were sampled using Malaise traps in early and late summer across ten forest sites in the Waitakere Ranges, New Zealand. At each trap, a range of local habitat variables were measu

The use of ultra-low power wake-up receivers (WuRx) can significantly reduce idle listening energy cost. To tailor a WuRx scheme to orthogonal frequency division multiplexing (OFDM) based systems, such as LTE-MTC or IEEE 802.11, the wake-up signal (WUS) also needs to follow OFDM principles to avoid interfering with other transmissions in the same shared bandwidth. Here, we address this particular

Higher socioeconomic status (SES) is associated with lower mortality, and this correlation has been confirmed using different indicators across several geographical settings. Nevertheless, the timing of the emergence of the SES gradient remains unclear. We used individual-level longitudinal data for a regional population in southern Sweden covering the period between 1813 and 2014, and we applied

OBJECTIVE: To explore the prevalence and reproducibility of paradoxically increased nasal airway resistance after decongestion of the nasal mucosa as well as to identify patient-related factors associated with it.DESIGN: Retrospective analysis of all rhinomanometric measurements carried out at one ENT department in Sweden in the time between 1990 and 2010. In the baseline material, 207 of 4435 pat

In this paper we address the energy consumption of the Constraint Application Protocol (CoAP) and the Message Queue Telemetry Transport (MQTT) protocol and compare their overhead. We also pay attention to the use case of security in IoT and analyze the energy consumption when using TLS/DTLS for the two protocols. In our experiments we use ESP32 with libcoap, MQTT, and mbed TLS libraries and conduc

ObjectivesMindfulness, positive self-related attitudes and secure attachment have been shown to protect against psychopathology during adolescence, but it is unknown how these factors are related to each other and which are most strongly linked to psychopathology symptoms.MethodsA cross-sectional research design was used with a large sample of adolescents (aged 14 to 18 years; n = 1660) that compl

As a solution to solving energy consumption and environment problems, photovoltaics has become one type of the promising devices to convert solar energy into electricity directly. In some special areas like in space, a kind of photovoltaics with lightweight and reliable properties is needed to supply power. Therefore, photovoltaics based on the group III-V semiconductor nanowires has been emerged

Den flerspråkiga texten bör studeras och förstås som en situerad händelse. Det är utgångspunkten i denna artikel, som med Caroline Bergvall och hennes ensembles framförande av Drift i norra Italien i september 2018 – och hennes bok med samma namn från 2014 – som exempel undersöker hur och ifall Roman Jakobsons kommunikationsmodell från 1958 kan bidra till en djupare förståelse av verket. Genom att

We define a ray, show how to use ray intervals, and demonstrate how to specify a ray using DirectX Raytracing (DXR).

The traditional quadratic formula is often presented as the way to compute the intersection of a ray with a sphere. While mathematically correct, this factorization can be numerically unstable when using floating-point arithmetic. We give two little-known reformulations and show how each can improve precision.
