Identification of tumor tissue in thin pathological samples via femtosecond laser-induced breakdown spectroscopy and machine learning
(2023-06-08)
In the treatment of most newly discovered solid cancerous tumors, surgery remains the first treatment option. An important factor in the success of these operations is the precise identification of oncological safety margins to ensure the complete removal of the tumor without affecting much of the neighboring healthy tissue. Here we report on the possibility of applying femtosecond Laser-Induced Breakdown Spectroscopy (LIBS) combined with Machine Learning algorithms as an alternative discrimination technique to ...

A multiscale approach reveals elaborate circulatory system and intermittent heartbeat in velvet worms (Onychophora)
(2023-04-28)
An antagonistic hemolymph-muscular system is essential for soft-bodied invertebrates. Many ecdysozoans (molting animals) possess neither a heart nor a vascular or circulatory system, whereas most arthropods exhibit a well-developed circulatory system. How did this system evolve and how was it subsequently modified in panarthropod lineages? As the closest relatives of arthropods and tardigrades, onychophorans (velvet worms) represent a key group for addressing this question. We therefore analyzed the entire circulatory ...

Determination and Modeling of Proximate and Thermal Properties of De-Watered Cassava Mash (Manihot esculenta Crantz) and Gari (Gelatinized cassava mash) Traditionally Processed (In Situ) in Togo
(2023-09-27)
The roasting process of Gari (Gelatinized cassava mash), a shelf-stable cassava product, is energy-intensive. Due to a lack of information on thermal characteristics and scarcity/rising energy costs, heat and mass transfer calculations are essential to optimizing the traditional gari procedure. The objective of this study was to determine the proximate, density, and thermal properties of traditionally processed de-watered cassava mash and gari at initial and final processing temperatures and moisture contents (MCwb). ...

Mobility Hubs: A Way Out of Car Dependency Through a New Multifunctional Housing Development?
(2023-07-25)
Today’s urban design of new quarters in the fringes of German metropolises shows a renaissance of the garage building as a cluster for car parking. In contrast to the past, parking garages are planned as multifunctional “mobility hubs.” Planners enrich them with new mobility and sharing options and incorporate sports or social infrastructure facilities on the roof and the ground floor, thus contributing to vibrant neighborhoods. In contrast to the internationally renowned example of Nordhavn (Copenhagen), we observe ...

An updated world checklist of velvet worms (Onychophora) with notes on nomenclature and status of names
(2023-11-16)
More than a decade has passed since the publication of the only world checklist available for Onychophora. During this period, numerous nomenclatural acts and taxonomic changes have been suggested within the group and a wealth of novel data has been published on many taxa. Herein, the up-to-date taxonomic scenario within Onychophora is presented, with appraisal of name status. This checklist covers both extant (Peripatidae and Peripatopsidae) and fossil taxa, and each species is accompanied by information on synonyms, ...

An Exploratory Analysis of Transactive Interaction Patterns in Cooperative Learning Using Sequential Analysis
(2023-08-03)
For cooperative learning to be effective, the quality of student–student interaction is crucial. Interactions, which are transactive in nature, are positively related to students’ learning success during cooperative learning. However, little is known about typical interaction patterns during transactive interaction in face-to-face cooperative learning. Therefore, the current study aims to analyze typical interaction patterns of transactive interaction in cooperative learning. Sixty-eight students from seventh to tenth ...

Is It the Judge, the Sender, or Just the Individual Message? Disentangling Person and Message Effects on Variation in Lie-Detection Judgments
(2023-02-15)
Research suggests that people differ more in their ability to lie than in their ability to detect lies. However, because studies have not treated senders and messages as separate entities, it is unclear whether some senders are generally more transparent than others or whether individual messages differ in their transparency of veracity regardless of senders. Variance attributable to judges, senders, and messages was estimated simultaneously using multiple messages from each sender (totaling more than 45,000 judgments). ...

Efficacy of supply chain relationships – differences in performance appraisals between buyers and suppliers
(2023-02-28)
This paper examines the efficacy of three supply chain relationship factors: trust, commitment, and relationship specific investment (RSI) in affecting firms’ cooperation, innovation and financial performance, comparing buyers’ and suppliers’ perspectives. A questionnaire survey was conducted in mainland China. Two independent samples with 101 and 108 responses respectively from the Chinese business buyers and suppliers were collected by visiting nine large annual exhibitions. Both samples involved buyer–supplier ...

Urbanisation threats to dairy cattle health: Insights from Greater Bengaluru, India
(2023-10-05)
Complex urbanisation dynamics, on the one hand, create a high demand for animal products, and on the other hand put enormous pressure on arable land with negative consequences for animal feed production. To explore the impact of accelerated urbanisation on dairy cattle health in urban farming systems, 151 farmers from different parts of the Greater Bengaluru metropolitan area in India were individually interviewed on aspects addressing cattle management and cattle health. In addition, 97 samples of forages from the ...

Soil respiration under different N fertilization and irrigation regimes in Bengaluru, S-India
(2023-09-15)
Rapid urbanization in many countries of the Global South has led to intensification of urban and peri-urban agriculture (UPA) whose effects on the soils’ physical, chemical, and microbial properties have been hardly studied. We therefore investigated the effects of different intensity levels, exemplified by three rates of mineral nitrogen (N) addition and irrigation on CO₂ emissions in typical crops during the wet (Kharif) and dry (Rabi) season on a Nitisol in Bengaluru, S-India. Respiration data were collected from ...
