Laccases are multicopper oxidases capable of oxidizing a broad range of phenolic and non-phenolic compounds, making them attractive biocatalysts for lignin valorization and environmental applications. In this work, two bacterial laccases, LacA from Bacillus amyloliquefaciens and MEK from Psychrobacter sp., were recombinantly produced in Escherichia coli BL21 (DE3), purified, and characterized to s
There is a strong mortality gradient by socioeconomic status in most of today’s developedcountries, which has spurred both scientific and policy interest. Despite its importance, westill do not have a full understanding of the causes of this gradient, nor about when itemerged. In this paper we study socioeconomic differences in adult mortality for men andwomen in Sweden over an almost 200-year per
This thesis examines the audiovisual productions featuring anashid released by Hamas’s armed wing, the Al-Qassam Brigades, between October 7, 2023, and October 10, 2025, in an attempt to understand whether and how they function as mechanisms of ontological security. The existing literature on Hamas largely overlooks its cultural materials when addressing issues related to the governance of the Gaz
Organisations operating in controversial industries face persistent legitimacy challenges due to the morally controversial nature of their core activities, making communication essential for maintaining stakeholder support and justifying organisational existence. This study examines how BAE Systems constructs legitimacy through corporate communication in its 2025 Annual Report, with particular foc
In a saturated digital marketplace, brands increasingly rely on storytelling to fos-ter WOM advocacy. However, it remains unclear whether storytelling directly triggers advocacy or if cognitive attitudes mediate this relationship. This study investigates the psychological pathway to brand advocacy by integrating the vis-ual, narrative, and symbolic dimensions of brand storytelling with Ajzen’s (19
The study discussed in this article aimed to understanding how pre-activity formulations are designed and accomplished by mothers in play interactions as everyday interactional business. Here, we report specifically on instances during the lab-based interactions where the mother orients to the lab-based task of singing with their infant, and discuss potential implications of such participant orien
Freshwater blooms of the microcystin-producing (toxigenic) cyanobacterium Microcystis may cause severe damage to human health and the environment. However, toxigenic and non-toxigenic strains co-exist within single blooms, and microcystin concentration in the water varies throughout the season. We hypothesized that strains that produce and do not produce microcystins represent different genotypes.
Private equity (PE) investment changes not only who owns firms but also how they are governed. In founder-led firms, this transition is particularly complex because authority, decision-making, and organizational identity are closely tied to the founder. Existing research explains private equity governance primarily through monitoring and value-creation mechanisms, but less is known about how the i
Generative AI promises substantial productivity gains, but many initiatives fail. This column argues that outcomes depend on readiness, not technology alone. We examine AI transformation requirements across organizational, individual, and technological dimensions, highlighting why engineering practices, human factors, and strategic clarity determine success.
This article examines Karl Ove Knausgård’s novel Morgenstjernen (2020, The Morning Star) as a series of interconnected pre-apocalyptic narratives. Using the framework of econarratology alongside the concept of ‘hyperobjects’ and terminology that points to the interconnectedness of all systems, I explore how the narratives we are able to tell in a changing world affect both ourselves and our relati
Purpose: To examine whether generative AI adoption influences analyst forecast error and bias, and whether the relationship differs across firms with different characteristics. Methodology: The study applies a quantitative panel-data approach using pooled OLS and firm fixed effects regressions. Interaction models are used to examine whether firm size, segment complexity, intangible intensity an
Background: The objective of this study was to explore the potential of Airspace Dimension Assessment (AiDA) to rapidly determine the type and severity of airway obstruction, detect emphysema in individuals with chronic airflow limitation (CAL), and distinguish it from non-emphysematous obstruction, asthma, and absence of respiratory disease with normal spirometry. Methods: Among the 744 participa
The theory of optimal control on positive cones has recently identified several new problem classes where the Bellman equation can be solved explicitly, in analogy with classical linear quadratic control. In this paper, the idea is extended to minimax adaptive control, yielding exact solutions to instances of the Bellman equation for dual control. In particular, this allows for optimization of the
This paper presents NMCu-CNN, a near-memory computing (NMC) co-processor for the hardware acceleration of convolutional neural networks (CNNs) on a low-power, flexible MCU platform. The scalable architecture and the selected platform enable adaptability to the rapidly evolving Edge AIoT landscape, where energy and performance requirements are constrained. Application-tailored NMC units, equipped w
Ultraviolet radiation exposure and a fair pigmentation phenotype are well-established risk factors for primary cutaneous melanoma. However, the prognostic relevance of these risk factors is largely unexplored in metastatic disease. The aim of this study was to examine whether phenotypic characteristics and sun exposure patterns affect the prognosis of metastatic melanoma with immunotherapy availab
In many raptors and owls the male is the main provider of food in the early phase of the nestling period while the female incubates the eggs and broods the young. In the nestling period the female often helps the male to feed the young, but the factors affecting whether and when she leaves the brood to hunt have not been investigated in detail. We present a dynamic state variable model that analys
The BhMIR32 xyn11A gene, encoding an extracellular endoxylanase of potential interest in bio-bleaching applications, was amplified from Bacillus halodurans MIR32 genomic DNA. The protein encoded is an endo-1,4-beta-xylanase belonging to family 11 of glycosyl hydrolases. Its nucleotide sequence was analysed and the mature peptide was subcloned into pET22b(+) expression vector. The enzyme was over-e
Late Precambrian and Palaeozoic platform sediments from the Central-South Taimyr Peninsula (Arctic Siberia) are all remagnetised. The remagnetisation is prefold and is related to thermal remagnetisation caused by Taimyr Trap magmatism. The remagnetisation age is estimated to 220-230 Ma and, hence, is considerably younger than the ca. 251 Ma age for the main body of Siberian Trap flood basalts. The
Pollen analyses and AMS C-14 measurements were performed on lacustrine sediments and peat deposits from the former crater lake Steregoiu in a mid-altitude area in the Gutaiului Mountains in NW Romania in order to provide a detailed reconstruction of the vegetational development of the area during the Late-Glacial and Holocene. The bottom sediments are siliciclastic and were deposited probably duri
