Temperature and Tree Size Explain the Mean Time to Fall of Dead Standing Trees across Large Scales
AbstractDead standing trees (DSTs) generally decompose slower than wood in contact with the forest floor. In many regions, DSTs are being created at an increasing rate due to accelerating tree mortality caused by climate change. Therefore, factors determining DST fall are crucial for predicting dead wood turnover time but remain poorly constrained. Here, we conduct a re-analysis of published DST f
Capturing the spatiotemporal variations in the gross primary productivity in coastal wetlands by integrating eddy covariance, Landsat, and MODIS satellite data : A case study in the Yangtze Estuary, China
Accurate monitoring of the spatiotemporal variations in the gross primary productivity (GPP) in coastal wetlands is essential for blue carbon quantification. However, the currently available moderate-spatial-resolution GPP algorithms and products may contain large uncertainties and may rarely meet the demands of tidal wetland research. In this paper, we examine two statistical methods, namely, sim
Exposure to phthalates and DiNCH among preschool children in Sweden : Urinary metabolite concentrations and predictors of exposure
Several plasticizing chemicals induce endocrine disrupting effects in humans, and the indoor environment is suggested to be a source of exposure. As children are particularly vulnerable to the effects from exposure to endocrine disrupting chemicals (EDCs), it is essential to monitor exposure to EDCs such as phthalates and non-phthalate plasticizers in indoor environments intended for use by childr
Differentiated knowledge bases and catch-up in creative industries – A case of the online game industry in China
Catch-up phenomena have been studied intensively in many manufacturing industries, but they have not been well explored in creative industries. Moreover, the internal heterogeneity of different segments within a specific industry has also largely been overlooked in the catch-up literature. This paper fills these gaps by analyzing the catch-up of a creative industry—the online game industry in Chin
Realisations of elliptic operators on compact manifolds with boundary
This paper investigates realisations of elliptic differential operators of general order on manifolds with boundary following the approach of Bär-Ballmann to first order elliptic operators. The space of possible boundary values of elements in the maximal domain is described as a Hilbert space densely sandwiched between two mixed order Sobolev spaces. The description uses Calderón projectors which,
IRF1 regulates self-renewal and stress-responsiveness to support hematopoietic stem cell maintenance
Inflammatory mediators induce emergency myelopoiesis and cycling of adult hematopoietic stem cells (HSCs) through incompletely understood mechanisms. To suppress the unwanted effects of inflammation and preserve its beneficial outcomes, the mechanisms by which inflammation affects hematopoiesis need to be fully elucidated. Rather than focusing on specific inflammatory stimuli, we here investigated
Risk factors of newly detected and masked untreated hypertension in a South Asian population of Type-2 diabetes patients
An automated buffer management system for small-scale continuous downstream bioprocessing
Buffer management for biopharmaceutical purification processes include buffer preparation, storage of buffers and restocking the buffers when needed. This is usually performed manually by the operators for small scale operations. However, buffer management can become a bottleneck when running integrated continuous purification processes for prolonged times, even at small scale. To address this iss

Investigating thermally induced aggregation of Somatropin- new insights using orthogonal techniques
Three orthogonal techniques were used to provide new insights into thermally induced aggregation of the therapeutic protein Somatropin at pH 5.8 and 7.0. The techniques were Dynamic Light Scattering (DLS), Asymmetric Flow-Field Flow-Fractionation (AF4), and the TEM-based analysis system MiniTEM™. In addition, Differential Scanning Calorimetry (DSC) was used to study the thermal unfolding and stabi
Temporal multimodal single-cell profiling of native hematopoiesis illuminates altered differentiation trajectories with age
Aging negatively affects hematopoiesis, with consequences for immunity and acquired blood cell disorders. Although impairments in hematopoietic stem cell (HSC) function contribute to this, the in vivo dynamics of such changes remain obscure. Here, we integrate extensive longitudinal functional assessments of HSC-specific lineage tracing with single-cell transcriptome and epitope profiling. In cont
Beyond Massive MIMO : Trade-offs and Opportunities with Large Multi-Antenna Systems
After the commercial emergence of 5G, the research community is already putting its focus on proposing innovative solutions to enable the upcoming 6G. One important lesson put forth by 5G research was that scaling up the conventional multiple-input-multiple-output (MIMO) technology by increasing the number of antennas could be extremely beneficial for effectively multiplexing data streams in the s
Högskolepedagogisk utveckling och forskning : Gränsarbete kring ett kunskapsområde i universitetets hjärta. En kommentar till Wide samt Scheja och Bolander Laksov
Vid Örebro universitet anordnades våren 2021 för andra gången konferensen Forskning om högre utbildning. Ett tema för konferensen var utveckling av högskolepedagogisk forskning. Högre utbildning publicerar nu tre texter på detta tema som en fördjupad diskussion. De kan läsas var för sig eller tillsammans. Den första utgörs av Sverre Wides inledningsanförande från konferensen. Efter inbjudan från rIn spring 2021, Örebro University arranged the second Swedish conference for Research in Higher Education. One of the themes for the conference was the development of higher education studies as a specific branch of this research. Our journal, Högre utbildning, now publishes three contributions linked to this theme as in-depths essays. These may be read separately or together. The first consists o
Accelerated cropland expansion into high integrity forests and protected areas globally in the 21st century
Intact forests and protected areas (PAs) are central to global biodiversity conservation and nature-based climate change mitigation. However, cropland encroachment threatens the ecological integrity and resilience of their functioning. Using satellite observations, we find that a large proportion of croplands in the remaining forests globally have been gained during 2003–2019, especially for high-
A model of decentralized vision in the sea urchin Diadema africanum
Sea urchins can detect light and move in relation to luminous stimuli despite lacking eyes. They presumably detect light through photoreceptor cells distributed on their body surface. However, there is currently no mechanistic explanation of how these animals can process light to detect visual stimuli and produce oriented movement. Here, we present a model of decentralized vision in echinoderms th
Silicon fertilization enhances the resistance of tobacco plants to combined Cd and Pb contamination : Physiological and microbial mechanisms
Remediation of soil contaminated with cadmium (Cd) and lead (Pb) is critical for tobacco production. Silicon (Si) fertilizer can relieve heavy metal stress and promote plant growth, however, it remains unknown whether fertilization with Si can mitigate the effects of Cd and Pb on tobacco growth and alter microbial community composition in polluted soils. Here we assessed the effect of two organic
The Association Between Quadriceps Strength and Synovitis in Knee Osteoarthritis : An Exploratory Study From the Osteoarthritis Initiative
OBJECTIVE: The aim of this study was to explore the association between quadriceps strength and synovitis in knee osteoarthritis (KOA). METHODS: This study was derived from the Osteoarthritis Initiative (OAI), which recruited adults from the OAI cohort with or at risk of KOA. Knees with complete records of isometric quadriceps strength and effusion-synovitis and Hoffa-synovitis assessments were in
Differences in mating system and predicted parental conflict affect post-pollination reproductive isolation in a flowering plant
Mating system shifts from outcrossing to selfing are frequent in plant evolution. Relative to outcrossing, selfing is associated with reduced parental conflict over seed provisioning, which may result in postzygotic, asymmetric, reproductive isolation in crosses between populations of different mating systems. To test the hypothesis that post-pollination reproductive isolation between populations
Rapid evolution of sex role specialization in a hermaphrodite under sex-limited selection
The evolution of separate sexes from hermaphroditism is thought to have occurred independently many times, and may be linked to the evolution of sex chromosomes. Even though we have a good understanding of the theoretical steps in the evolution of sex chromosomes from a hermaphrodite ancestor, the initial stages are still hard to study in animals because many well-studied animal sex chromosome sys
