Covariational reasoning in Bayesian situations
(2024-01-27)
Previous studies on Bayesian situations, in which probabilistic information is used to update the probability of a hypothesis, have often focused on the calculation of a posterior probability. We argue that for an in-depth understanding of Bayesian situations, it is (apart from mere calculation) also necessary to be able to evaluate the effect of changes of parameters in the Bayesian situation and the consequences, e.g., for the posterior probability. Thus, by understanding Bayes’ formula as a function, the concept ...

On the Performance of Malleable APGAS Programs and Batch Job Schedulers
(2024-01-18)
Malleability—the ability for applications to dynamically adjust their resource allocations at runtime—presents great potential to enhance the efficiency and resource utilization of modern supercomputers. However, applications are rarely capable of growing and shrinking their number of nodes at runtime, and batch job schedulers provide only rudimentary support for such features. While numerous approaches have been proposed to enable application malleability, these typically focus on iterative computations and require ...

Data‑driven prediction of the surface layer state in hard‑turning for optimization of component quality
(2024-01-30)
Data-driven approaches are an effective solution for modeling problems in machining. To increase the service life of hardturned components, it is important to quantify the correlation between the cutting parameters such as feed rate, cutting speed and depth of cut and the near-surface properties. For obtaining high-quality models with small data sets, different data-driven approaches are investigated in this contribution. Additionally, models that enable uncertainty quantification are crucial for effective decision-making ...

Gradual Coordination and Reversible P–P Bond Activation of a P3-Unit with Transition Metal Carbony
(2024-03-20)
Coordination of a stereochemically defined P3-chain to a series of transition metal carbonyls [M(CO)x]z− (M = Mn (x = 5, z = 1), Fe (x = 4, z = 2) or Co (x = 4, z = 1)) is explored using a 3]ferrocenophane scaffold. A gradual transition from 𝜼1-, 𝜼2- to 𝜼3-coordination is observed where in the 𝜼2-mode the terminal positions of the phosphorus chain are bridged. With an excess of cobalt carbonyl successive P–P bond activation and gradual separation of the central phosphorus atoms from the phosphorus chain has been ...

Technoeconomic analysis of standalone hybrid renewable energy systems for telecommunication sector under different climatic conditions in Saudi Arabia
(2024-04-05)
Reliance on conventional fossil fuels to fulfil the extensively increasing energy demands due to industrial development is becoming a financial burden and a huge source of global warming. Saudi Arabia, possessing nearly 15% of the world's oil reserves, confronts an intricate scenario where approximately 53% of government revenue is oil-dependent, rendering it the 11th largest global emitter of carbon gases. This proclivity underscores the urgent need for transitioning towards renewable energy sources to alleviate ...

Differences in enteric methane emissions across four dairy production systems in the urbanizing environment of an Indian megacity
(2024-01-17)
Low- and middle-income countries (LMICs) are rapidly urbanizing, leading to a high demand for high-quality animal products. Production increase is seen as a key to meeting this demand and reducing the global environmental impact of low-yielding dairy production system (DPS) often found in LMICs. Therefore, the present study assesses the relationship between enteric methane emissions and different dairy production strategies, taking DPS in the rural–urban interface of Bengaluru, an Indian megacity, as a case study. ...

UVC Irradiation as a Surface Treatment of Polycarbonate to Generate Adhesion to Liquid Silicone Rubber in an Overmolding Process
(2024-04-18)
This study investigates the adhesion properties of polycarbonate (PC) and liquid silicone rubbers (LSR) through surface activation using ultraviolet C (UVC) radiation. While self-adhesive LSRs adhere easily to certain thermoplastic composites such as polybutylene terephthalate (PBT) and polyamides (PAs), bonding to PC typically requires surface treatment due to the lack of compatible functional groups. Previous methods like plasma or flame treatment have been effective, but the use of UVC radiation for surface ...

Towards collaborative planning: deliberative knowledge utilisation and conflict resolution in urban regeneration in South China
(2024-03-22)
Urban regeneration in post-reform China has become a fertile ground for the transition towards collaborative planning, which serves as a powerful tool for managing conflicts and addressing complex urban challenges. This article aims to delve into the micro-level processes that underpin the emergence of collaborative planning in practical urban regeneration projects in China. By shedding light on these micro-level processes of conflict resolution, we aim to provide a deeper understanding of how collaborative planning ...

A hitchhiker’s guide: estimates of microbial biomass and microbial gene abundance in soil
(2024-03-19)
Information on microbial biomass carbon (MBC) is crucial to assess their stocks and role for plant nutrient release in soil. Next to fumigation-extraction, molecular methods are routinely used to estimate the contribution of fungi, bacteria, and archaea to the soil microbial community. However, more information on the links between these different indices would deepen the understanding of microbial processes. The current study is based on 11 datasets, which contain MBC and MBN data obtained by fumigation-extraction ...

Why has animal science not led to improved farm animal health and welfare?
(2024-01-05)
To sustain the economic viability of a livestock farm in a global market, characterised by a price undercutting competition, farmers are forced to adapt to what the market demands. At the same time, they have to care for the functionality of the farm system as a whole and of the subsystems, such as the farm animals, so that they for their part they can contribute to an economic success. Now, that animal health and welfare (AHW) has become an increasingly important issue for citizens and consumers, not only the decision ...
