Published: July 2022

ZusammenfassungDieser Beitrag untersucht, ob externe Interventionen, in Form von Forschung und/oder Wissenschaftskommunikation, als Mediator für Innovationen in Krisenzeiten in der Tourismusbranche fungieren können. Dabei wird anhand dreier Case Studies diskutiert, inwiefern die Corona-Krise ein Window-of-opportunity für innovative Geschäftsmodelle im Tourismus darstellen konnte. Die Projektergebnisse geben Hinweise darauf, dass Krisen im Allgemeinen und Wissenschaftskommunikation im Speziellen als Push-Faktoren Innovationen befördern können. Zwar kam es bei den Projektpartnern zu einer Entwicklung von Innovationen im Projektzeitraum, jedoch wurde die Implementierung vermehrt in eine unbestimmte Zukunft verschoben. Durch die damit verbundene Rückkehr zum Status-Quo blieben die angestoßenen Innovationen zu einem Großteil auf einer konzeptionellen Ebene. Dies deutet auf eine Attitude-behavior-gap in Bezug auf die Schaffung und Umsetzung von Innovationen in Krisenzeiten.

Abstract
The stannide YbRhSn2 has been synthesized. An arc-melted Rh25Sn48 precursor sample was reacted with ytterbium in a sealed tantalum ampoule in an induction furnace. The structure of YbRhSn2 was refined from single-crystal X-ray diffractometer data: MgCuAl2 type, Cmcm, a = 433.10(3), b = 1076.63(8), c = 739.36(5) pm, wR2 = 0.0676, 444 F
2 values and 16 variables. The rhodium and tin atoms form a three-dimensional [RhSn2]
δ−
polyanionic network with short Rh–Sn (271–273 pm) and Sn–Sn (301–324 pm) distances. The tin substructure is an orthorhombically distorted lonsdaleite network. YbRhSn2 shows paramagnetic behavior with a reduced magnetic moment of 2.2(1) µB per ytterbium atom, classifying it as an intermediate-valent compound.

Abstract
In order to obtain the best scheme of safety production and operation decision-making of a smart factory and improve the rapid response ability of product information of a smart factory, the safety production detection algorithm of a smart factory is designed by using programmable computer (PC) control technology. The main interface, login interface, function interface, and navigation interface are designed, respectively, to realize the front-end design of the smart factory safety production detection platform. Based on PC control technology, the hardware equipment of perception layer, network layer, and application layer are installed, and on this basis, the database of the smart factory safety production detection platform is established. Once the operation data information is collected and detected, it is stored to the equipment fault experience knowledge base, and the fault diagnosis method of the minimum cut set of the fault tree is used to implement the on-site equipment diagnosis of the underlying Internet of Things of the smart factory, and finally the information sharing function of safety production detection through the information transmission of the safety production links of each smart factory is realized. Experiments show that the throughput data of the designed algorithm run stably, improve the control accuracy of safety production, and effectively improve the work efficiency.
Enhanced Stability of Complex Sound Representations Relative to Simple Sounds in the Auditory Cortex
Authors: Suri Harini , Rothschild Gideon 
Published: July 2022

AbstractTypical everyday sounds, such as those of speech or running water, are spectrotemporally complex. The ability to recognize complex sounds (CxSs) and their associated meaning is presumed to rely on their stable neural representations across time. The auditory cortex is critical for the processing of CxSs, yet little is known of the degree of stability of auditory cortical representations of CxSs across days. Previous studies have shown that the auditory cortex represents CxS identity with a substantial degree of invariance to basic sound attributes such as frequency. We therefore hypothesized that auditory cortical representations of CxSs are more stable across days than those of sounds that lack spectrotemporal structure such as pure tones (PTs). To test this hypothesis, we recorded responses of identified layer 2/3 auditory cortical excitatory neurons to both PTs and CxSs across days using two-photon calcium imaging in awake mice. Auditory cortical neurons showed significant daily changes of responses to both types of sounds, yet responses to CxSs exhibited significantly lower rates of daily change than those of PTs. Furthermore, daily changes in response profiles to PTs tended to be more stimulus-specific, reflecting changes in sound selectivity, compared with changes of CxS responses. Last, the enhanced stability of responses to CxSs was evident across longer time intervals as well. Together, these results suggest that spectrotemporally CxSs are more stably represented in the auditory cortex across time than PTs. These findings support a role of the auditory cortex in representing CxS identity across time.

AbstractX-linked dystonia-parkinsonism (XDP) is an inherited, X-linked, adult-onset movement disorder characterized by degeneration in the neostriatum. No therapeutics alter disease progression. The mechanisms underlying regional differences in degeneration and adult onset are unknown. Developing therapeutics requires a deeper understanding of how XDP-relevant features vary in health and disease. XDP is possibly due, in part, to a partial loss ofTAF1function. A disease-specific SINE-VNTR-Alu (SVA) retrotransposon insertion occurs within intron 32 ofTAF1, a subunit of TFIID involved in transcription initiation. While all XDP males are usually clinically affected, females are heterozygous carriers generally not manifesting the full syndrome. As a resource for disease modeling, we characterized eight iPSC lines from three XDP female carrier individuals for X chromosome inactivation (XCI) status and identified clonal lines that express either the wild-type X or XDP haplotype. Furthermore, we characterized XDP-relevant transcript expression in neurotypical humans, and found that SVA-F expression decreases after 30 years of age in the brain and thatTAF1is decreased in most female samples. Uniquely in the caudate nucleus,TAF1expression is not sexually dimorphic and decreased after adolescence. These findings indicate that regional-specific, age-specific, and sex-specific mechanisms regulateTAF1, highlighting the importance of disease-relevant models and postmortem tissue. We propose that the decreasedTAF1expression in the adult caudate may synergize with the XDP-specific partial loss ofTAF1function in patients, thereby passing a minimum threshold ofTAF1function, and triggering degeneration in the neostriatum.
Theta-Phase Connectivity between Medial Prefrontal and Posterior Areas Underlies Novel Instructions Implementation
Authors: Formica Silvia , González-García Carlos , Senoussi Mehdi , Marinazzo Daniele , Brass Marcel 
Published: July 2022

AbstractImplementing novel instructions is a complex and uniquely human cognitive ability, which requires the rapid and flexible conversion of symbolic content into a format that enables the execution of the instructed behavior. Preparing to implement novel instructions, as opposed to their mere maintenance, involves the activation of the instructed motor plans, and the binding of the action information to the specific context in which this should be executed. Recent evidence and prominent computational models suggest that this efficient configuration of the system might involve a central role of frontal theta oscillations in establishing top-down long-range synchronization between distant and task-relevant brain areas. In the present EEG study (human subjects, 30 females, 4 males), we demonstrate that proactively preparing for the implementation of novels instructions, as opposed to their maintenance, involves a strengthened degree of connectivity in the theta frequency range between medial prefrontal and motor/visual areas. Moreover, we replicated previous results showing oscillatory features associated specifically with implementation demands, and extended on them demonstrating the role of theta oscillations in mediating the effect of task demands on behavioral performance. Taken together, these findings support our hypothesis that the modulation of connectivity patterns between frontal and task-relevant posterior brain areas is a core factor in the emergence of a behavior-guiding format from novel instructions.
Effects and safety of metformin in patients with concurrent diabetes mellitus and chronic obstructive pulmonary disease: a systematic review and meta-analysis
Authors: Liang Ziting , Yang Mengge , Xu Changjuan , Zeng Rong , Dong Liang 
Published: July 2022

Aim
This study aimed to investigate the effects and safety of metformin in patients with concurrent diabetes mellitus (DM) and chronic obstructive pulmonary disease (COPD).

Methods
PubMed, Embase, Web of Science, the China National Knowledge, and Cochrane Database were searched to find studies that examined the effects and safety of metformin in patients with concurrent DM and COPD. We conducted a meta-analysis with a risk ratio (RR) and assessed the quality of included studies and pooled evidence.

Results
Eight studies were involved. Metformin was associated with lower risk of COPD-related hospitalizations (RR: 0.72, 95% CI: 0.53–0.98; I2= 89%) and all-cause mortality (RR: 0.60, 95% CI: 0.36–1.01, I2= 69%) in patients with concurrent DM and COPD, but did not increase the risk of hyperlactatemia (RR: 1.14, 95% CI: 0.92–1.41, I2 = 8%).

Conclusions
Metformin use is associated with lower risk of COPD-related hospitalizations and risk of all-cause mortality without increasing the risk of hyperlactatemia. Considerations should be given to conduct more high-quality randomized trials involving larger samples.
Matrix metalloproteinase-induced cervical extracellular matrix remodelling in pregnancy and cervical cancer

Graphical abstract

Abstract
The phenomenal extracellular matrix (ECM) remodelling of the cervix that precedes the myometrial contraction of labour at term or preterm appears to share some common mechanisms with the occurrence, growth, invasion and metastasis of cervical carcinoma. Matrix metalloproteinases (MMPs) are zinc-dependent endopeptidases that are pivotal to the complex extracellular tissue modulation that includes degradation, remodelling and exchange of ECM components, which contribute to homeostasis under normal physiological conditions such as cervical remodelling during pregnancy and puerperium. However, in cancer such as that of the uterine cervix, this extensive network of extracellular tissue modulation is altered leading to disrupted cell–cell and cell–basement membrane adhesion, abnormal tissue growth, neovascularization and metastasis that disrupt homeostasis. Cervical ECM remodelling during pregnancy and puerperium could be a physiological albeit benign neoplasm. In this review, we examined the pathophysiologic differences and similarities in the role of MMPs in cervical remodelling and cervical carcinoma.

Lay summary
During pregnancy and childbirth, the cervix, which is the barrel-shaped lower portion of the womb that connects to the vagina, gradually softens, shortens and opens to allow birth of the baby. This process requires structural and biochemical changes in the cervix that are stimulated by enzymes known as matrix metalloproteinases. Interestingly, these enzymes also affect the structural and biochemical framework of the cervix during cervical cancer, although cervical cancers usually occur after infection by human papillomavirus. This review is intended to identify and explain the similarities and differences between the structural and chemical changes in the cervix during pregnancy and childbirth and the changes seen in cervical cancer.
Recursion in Abstract Argumentation is Hard --- On the Complexity of Semantics Based on Weak Admissibility
Authors: Dvořák Wolfgang , Ulbricht Markus , Woltran Stefan 
Published: July 2022

We study the computational complexity of abstract argumentation semantics based on weak admissibility, a recently introduced concept to deal with arguments of self-defeating nature. Our results reveal that semantics based on weak admissibility are of much higher complexity (under typical assumptions) compared to all argumentation semantics which have been analysed in terms of complexity so far. In fact, we show PSPACE-completeness of all non-trivial standard decision problems for weak-admissible based semantics. We then investigate potential tractable fragments and show that restricting the frameworks under consideration to certain graph-classes significantly reduces the complexity. We also show that weak-admissibility based extensions can be computed by dividing the given graph into its strongly connected components (SCCs). This technique ensures that the bottleneck when computing extensions is the size of the largest SCC instead of the size of the graph itself and therefore contributes to the search for fixed-parameter tractable implementations for reasoning with weak admissibility.

Interseismic Masking of Fault Slip Deficit Rates by Earthquake Cycle Processes and Local Block Rotations
Authors: Meade Brendan J. 
Published: July 2022

Abstract
Interseismic geodetic observations at active boundaries contain information about tectonic motions and earthquake cycle processes. The combined effects of these two processes may serve to mask tectonic signals near active faults. Motivated by the observation of coseismic rotational motion during the 2016 Mw 7.8 Kaikōura New Zealand earthquake we develop idealized models for the masking of tectonic motions near blocks with local rotation poles. We show that differential interseismic velocities may reach local, rather than far field, maxima contributing to suppression of apparent slip deficit rates. This effect is most pronounced for small (&lt;100 km) tectonic blocks with deep (&gt;10 km) effective locking depths.

Unit Konservasi Budidaya Biofarmaka (UKBB) and Kampoeng Djamoe Organik Martha Tilaar (KaDO) are two medicinal plantation that possibly as resources for stingless bees nectar and pollen. This study was aimed to describe the foraging behavior of Tetragonula laeviceps in medicinal plantations, determine the plant species which become the pollen resources, and the distance between the colony and medicinal plants. Observation on foraging behavior were divided into three activities, i.e. flying out from the nest, returning the nest with pollen, and returning the nest without pollen. We found a similar pattern of numbers of bees returning to the nest with pollen in both UKBB and KaDO that occurred in the morning with the highest between 9 and 10 am and gradually decreased in the afternoon. The bees in UKBB showed highly number flying out from the nest in around 3 pm which might be the activites of resin collection. We identified 11 and 16 pollen types at the UKBB and the KaDO, respectively. The pollen in both locations are from the families Amaryllidaceae, Anacardiaceae, Clusiaceae, Cucurbitaceae, Ebenaceae, and Sapindaceae. Our results revealed that the distance range of medicinal plants from the bees hives was 13.4-113,3 m. Thus, this data indicate that the hives should be located in the distance of the bee forage. The medicinal pollen identified in the T. laeviceps pollen pot confirmed the role of the bees as the ecosystem service in the medicinal plantations.

Published: July 2022

By-products such as oil palm empty fruit bunches (EFB), palm kernel cake, and sawdust can be used as alternative feed. It contains nutrients needed by ruminants but is constrained by its high crude fiber content, including lignin, cellulose, and hemicellulose, and is low in protein. This study was conducted to evaluate the physical characteristics of the fermented media from plantation by-products using Pleurotus ostreotus as an alternative to ruminant animal feed. The experimental design was a completely randomized (CRD) with 3'3 factorial patterns with three replications. Factor A was the type of substrate, namely palm kernel cake, EFB, and acacia sawdust. Factor B was the length of fermentation, namely 0, 30, and 60 d. The data collected were analyzed by variance (ANOVA), and the results were significantly different. The observed variables were the mycelium growth rate, media weight, dry matter, organic matter, particle size, specific gravity, pile density, and compacted pile density. We conclude that the fermented sawdust gave the best growth speed of the P. ostreotus mycelia. The palm kernel cake substrate without storage showed good physical quality concerning particle size, pile density, and pile-compaction density. P. ostreotus fungus grew effectively and did not negatively impact the substrates' biomass, dry matter, and organic matter. Different substrate types give different physical characteristics to the P. ostreotus-fermented media.

Efektivitas Fungi Mikoriza Arbuskula pada Tanaman Singkong (Manihot esculenta) di Tanah Inceptisol Bogor
Authors: Khairiyah Yaumil , Widyastuti Rahayu , Badia Ginting Rohani Cinta 
Published: July 2022

Cassava is widely grown in Inceptisol. As agricultural land, the soil has several problems, i.e., high soil acidity, easily leached soil surface layers, unstable soil aggregates, and slow permeability. Arbuscular mycorrhizal fungi (AMF) form a symbiotic relationship with over 80% of higher plant species. However, the effectiveness of AMF on cassava has not been widely reported. This study aimed to determine the effect of AMF inoculants on the vegetative growth of cassava in Inceptisol. The AMF inoculants used were Gigaspora sp., Glomus manihotis, and a consortium of Acaulospora tuberculata and Glomus rubiforme. The experiment was performed in a Randomized Block Design with 8 treatments and 3 replications, i.e., M1 = G. manihotis; M2 = Gigaspora sp.; M3 = consortium of A. tuberculata-G. rubiforme; M4 consortium of G. manihotis-Gigaspora sp.; M5 consortium of G. manihotis-A. tuberculata-G. rubiforme; M6 consortium of A. tuberculata-G. rubiforme-Gigaspora sp.; and M7 consortium of G. manihotis-A. tuberculata-G. rubiforme-Gigaspora sp.; and control (as recommended dose of NPK fertilizers). In the AMF application treatment, 75% of the recommended NPK fertilizer was applied, thus saving 25% from the control. A total of 50 AMF spores were applied to each cassava plant and maintained for 8 weeks. The data were analyzed using the RStudio 4.1.1 program. The results showed that all treatments with AMF gave various effectiveness and could compete with the indigenous AMF. AMF application significantly increased the vegetative growth of cassava grown in Inceptisols, i.e., shoot and root dry weight, root length, P-uptake, and percentage of root infection. Application of G. manihotis and the consortium of A. tuberculata-G. rubiforme-Gigaspora sp. effectively increased cassava plants' growth for 8 weeks in Inceptisol. The AMF application could save 25% on the use of NPK fertilizers.
