Feeding ecology of monk sakis (Pithecia monachus) in a seasonally flooded forest in western Amazonia
Authors: Gottstein Malika , Morris Abigail Lauren , Heer Katrin , Heymann Eckhard W. 
Published: June 2023

AbstractSakis (genus Pithecia) are frugivorous primates with a preference for seeds that complete their diet with leaves and insects. Fruit pulp and seeds are known to have different nutritional characteristics that change during the process of ripening. The consumption of seeds can be an adaptation to changes in resource availability, as unripe seeds are a more steadily available resource than ripe pulp or young leaves. Here, we present the first study of the feeding ecology of monk sakis (Pithecia monachus). We investigated dietary composition and identified important feeding plants in a seasonally flooded forest within the Área de Conservación Regional Comunal Tamshiyacu–Tahuayo in Peruvian Amazonia. Throughout 20 months, we followed groups of monk sakis by foot and canoe and recorded 459 feeding events. Seeds were the most frequently consumed food item (49%), followed by pulp (mesocarp, pericarp or aril; 25%) and arthropods (22%). Leaves, bark, and flowers were ingested only sporadically. The importance of ripe seeds and arthropods in the diet of the monk sakis differed from other studies: we recorded the consumption of mostly ripe seeds and the share of arthropods was relatively high.
Laboratory evaluation of insect growth regulators against the spotted wing drosophila, Drosophila suzukii

Published: June 2023

AbstractDrosophila suzukii (Diptera: Drosophilidae) is an invasive species that causes great damages to many stone and small fruits, resulting in reduced fruit production and high economic losses. The concern about this pest has led to the research of a wide range of possible control methods. However, the main control strategies are still based in insecticide applications. The efficacy of different insect growth regulators (IGRs), which have better ecotoxicological profile than conventional pesticides, was evaluated to test their feasibility for the control of this pest. When adult flies fed for three days on artificial diet surface-treated with lufenuron, cyromazine or pyriproxyfen, no adult offspring developed. However, adult offspring production progressively recovered when flies were transferred to non-treated diet. When adult flies fed continuously for 19 days on surface-treated artificial diet, lufenuron, cyromazine and pyriproxyfen completely suppressed the production of viable offspring while azadirachtin and tebufenozide reduced offspring production by more than a half compared to the untreated control. Nevertheless, these were transient non-permanent effects since viable offspring was produced shortly after females fed on treated diet were transferred to non-treated diet. The results observed in additional choice and egg-transfer assays indicate a vertical transmission of lufenuron and cyromazine from treated females to their offspring whereas the effect of pyriproxyfen seems to be related to the feeding of larvae on treated diet, although effects on reproductive processes cannot be discarded. In addition, choice assays showed no repellent effect on oviposition by lufenuron, cyromazine and pyriproxyfen.

Abstract
Aim
In recent years, the mental health requirements of healthcare professionals have drawn attention as a significant public health issue and a danger to the provision of high-quality care. Healthcare workers are subjected to multiple stressors at work, which may negatively affect their physical, mental, and emotional health. This study aims to assess the prevalence of depression and fatigue among Egyptian healthcare workers (HCWs) and to assess factors associated with depression and fatigue.

Subject and methods
This cross-sectional survey used Google Form to build online questionnaires, including sociodemographic data, a 10-question fatigue assessment scale, and a depression assessment scale (PHQ-9 questionnaire). The study was conducted post-COVID-19 from November 28, 2022, to January 28, 2023.

Results
The study involved 1511 Egyptian HCWs with a mean age of 37.4±7.7 years (range 26-71 years); 73% were female. Physicians constituted 77.8% of the participants. Mild depression was found in 26.1% of the participants, 26.8% reported moderate, and 43.1% had severe depressive symptoms. Fatigue symptoms were encountered in 88.7%. The independent factors affecting depression were female gender, single, living in a rural area, having a chronic disease, working > 8 h/day, being a public hospital worker, and studying for postgraduate degrees. Age of 35 years or younger, female gender, and studying for postgraduates were found to independently affect fatigue.

Conclusion
Depression and fatigue are highly prevalent among Egyptian healthcare workers. Many factors related to the prevalence of depression and fatigue need to be considered to enhance the mental well-being of HCWs.
Life history data from the gateway to global ageing data platform: resources for studying life courses across Europe
Authors: Wahrendorf Morten , Deindl Christian , Lee Jinkook , Phillips Drystan 
Published: June 2023

AbstractResearch from a range of disciplines highlights the need to adopt a life course perspective that considers earlier life courses to explain outcomes in later life (e.g. later life health, cognitive ageing or retirement behaviour). This includes a more comprehensive assessment of earlier life courses over time and of how they are shaped by societal and political contexts. But quantitative data with detailed information on life courses that allow to address these questions are rare. Or, in case the data are available, the data are rather difficult to handle and appears to be underused. This contribution introduces the harmonized life history data from the gateway to global ageing data platform from two European Surveys, SHARE and ELSA, with data from 30 European countries. Besides providing some details on the collection of life history data in the two surveys, we also describe the way how raw data were rearranged in a user-friendly state sequence format and additionally give some examples based on the resulting data. This illustrates the potential of collected life history data from SHARE and ELSA, clearly going beyond the description of single aspects of the life course. By providing harmonized data of two prominent studies on ageing in Europe in a user-friendly format, the gateway to global ageing data platform provides a unique data source that is easily accessible for research, and permits to study life course and their links to later life in a cross-national perspective.

AbstractThe value of biofeedback before elective coronary computed tomography angiography (CCTA) to reduce patients’ heart rates (HR) was investigated in the current work. Sixty patients who received CCTA to exclude coronary artery disease were included in our study and separated into two groups: with biofeedback (W-BF) and without biofeedback (WO-BF). The W-BF group used a biofeedback device for 15 min before CCTA. HR was determined in each patient at four measurement time points (MTP): during the pre-examination interview (MTP1), positioning on the CT patient table before CCTA (MTP2), during CCTA image acquisition (MTP3), and after completing CCTA (MTP4). If necessary, beta-blockers were administered in both groups after MTP2 until a HR of less than 65 bpm was achieved. Two board-certified radiologists subsequently assessed the image quality and analyzed the findings. Overall, the need for beta-blockers was significantly lower in patients in the W-BF group than the WO-BF group (p = 0.032). In patients with a HR of 81–90, beta-blockers were not required in four of six cases in the W-BF group, whereas in the WO-BF group all patients needed beta-blockers (p = 0.03). The amount of HR reduction between MTP1 and MTP2 was significantly higher in the W-BF compared to the WO-BF group (p = 0.028). There was no significant difference between the W-BF and WO-BF groups regarding image quality (p = 0.179). By using biofeedback prior to elective CCTA, beta-blocker use could be decreased without compromising CT image quality and analysis, especially in patients with an initial HR of 81–90 bpm.
Hamiltonian Privilege

Published: June 2023

Abstract
We argue that Hamiltonian mechanics is more fundamental than Lagrangian mechanics. Our argument provides a non-metaphysical strategy for privileging one formulation of a theory over another: ceteris paribus, a more general formulation is more fundamental. We illustrate this criterion through a novel interpretation of classical mechanics, based on three physical conditions. Two of these conditions suffice for recovering Hamiltonian mechanics. A third condition is necessary for Lagrangian mechanics. Hence, Lagrangian systems are a proper subset of Hamiltonian systems. Finally, we provide a geometric interpretation of the principle of stationary action and rebut arguments for privileging Lagrangian mechanics.

AbstractEnzalutamide is known to strongly induce cytochrome P450 3A4 (CYP3A4). Furthermore, enzalutamide showed induction and inhibition of P-glycoprotein (P-gp) in in vitro studies. A clinical drug-drug interaction (DDI) study between enzalutamide and digoxin, a typical P-gp substrate, suggested enzalutamide has weak inhibitory effect on P-gp substrates. Direct oral anticoagulants (DOACs), such as apixaban and rivaroxaban, are dual substrates of CYP3A4 and P-gp, and hence it is recommended to avoid co-administration of these DOACs with combined P-gp and strong CYP3A inducers. Enzalutamide’s net effect on P-gp and CYP3A for apixaban and rivaroxaban plasma exposures is of interest to physicians who treat patients for venous thromboembolism with prostate cancer. Accordingly, a physiologically-based pharmacokinetic (PBPK) analysis was performed to predict the magnitude of DDI on apixaban and rivaroxaban exposures in the presence of 160 mg once-daily dosing of enzalutamide. The PBPK models of enzalutamide and M2, a major metabolite of enzalutamide which also has potential to induce CYP3A and P-gp and inhibit P-gp, were developed and verified as perpetrators of CYP3A-and P-gp-mediated interaction. Simulation results predicted a 31% decrease in AUC and no change in Cmax for apixaban and a 45% decrease in AUC and a 25% decrease in Cmax for rivaroxaban when 160 mg multiple doses of enzalutamide were co-administered. In summary, enzalutamide is considered to decrease apixaban and rivaroxaban exposure through the combined effects of CYP3A induction and net P-gp inhibition. Concurrent use of these drugs warrants careful monitoring for efficacy and safety.
Electrical Resistance of Hydrides Under High Pressure: Evidence of Superconductivity or Confirmation Bias?
Authors: Hirsch J. E. 
Published: June 2023

AbstractDuring the past 9 years, extensive experimental evidence has been presented that is claimed to demonstrate that hydrogen-rich materials under high pressure are high-temperature superconductors, as predicted by conventional BCS-electron–phonon theory. Foremost among the experimental evidence are electrical resistance measurements, which claimed to show that the resistivity of these materials falls well below that of the best normal metals within experimental accuracy. Here I propose an alternative explanation for the vanishingly small resistance reported for these materials that does not involve superconductivity.

Abstract

Background and aims
Belowground interspecific plant facilitation is supposed to play a key role in enabling species co-existence in hyperdiverse ecosystems in extremely nutrient-poor, semi-arid habitats, such as Banksia woodlands in southwestern-Australia. Manganese (Mn) is readily mobilised by Banksia cluster root activity in most soils and accumulates in mature leaves of native Australian plant species without significant remobilisation during leaf senescence. We hypothesised that neighbouring shrubs are facilitated in terms of Mn uptake depending on distance to surrounding cluster root-forming Banksia trees.

Methods
We mapped all Banksia trees and selected neighbouring shrubs within a study site in Western Australia. Soil samples were collected and analysed for physical properties and nutrient concentrations. To assesses the effect of Banksia tree proximity on leaf Mn concentrations [Mn] of non-cluster-rooted woody shrubs, samples of similarly aged leaves were taken. We used multiple linear models to test for factors affecting shrub leaf [Mn].

Results
None of the assessed soil parameters showed a significant correlation with shrub leaf Mn concentrations. However, we observed a significant positive effect of very close Banksia trees (2 m) on leaf [Mn] in one of the understorey shrubs. We found additional effects of elevation and shrub size.

Conclusions
Leaf micronutrient concentrations of understorey shrubs were enhanced when growing within 2 m of tall Banksia trees. Our model predictions also indicate that belowground facilitation of Mn uptake was shrub size-dependent. We discuss this result in the light of plant water relations and shrub root system architecture.
Assessment of selected environmental and economic factors for the development of electro-mobility in Poland

Published: June 2023

AbstractElectromobility is now widely recognized as a remedy for the growing level of greenhouse gas emissions from the transport sector. The result of this approach is the agreement of the European Commission with the member states regarding the achievement of CO2-free emission of the new fleet of passenger cars by 2035 through the use of battery electric vehicles. However, it should be emphasized that currently, not every country in the European Union has electricity sources with low CO2 emission (Proposal for a REGULATION… (EU) 2019/631), which in fact can contribute to a lower environmental effect than expected. The amount of environmental impact of a battery electric vehicle depends mainly on the type of energy mix of the country in which it is used. In view of the above, the first scientific objective of the article is a comparative assessment of environmental impact, using the LCA (Life Cycle Assessment), the phase of use of passenger cars with conventional drive in relation to battery electric vehicles consuming electricity from the power grid in Poland and in Italy. The results of the LCA analysis, phases of BEV use in Poland indicate a higher level of environmental impact in relation to ICE due to the generation of electricity, for the most part from hard coal. Nevertheless, in Poland, as in other EU countries, an electromobility support system is being implemented. The successful implementation of electromobility depends on the environmental awareness of BEV users. The scientific cognitive aspect of the BEV purchase decisions of the Polish society is carried out using a survey questionnaire with the use of a non-random selection of the research sample (convenient selection). The aim of this cross-sectional survey was to confront the results of the environmental impact of the BEV use phase with the knowledge of the Polish society, as well as to learn about purchasing factors (future and current users). The results of the survey questionnaire demonstrate the low level of knowledge of the Polish society on the impact of the BEV use phase in Poland. This can be the result of media coverage in which BEV is presented as ecological transport. The aim of the article is not to depreciate the environmental performance of BEVs, but to draw attention to the fact that, to a large extent, the environmental impact of the BEV use phase depends on the place of use (country), and precisely the type of energy mix of a particular country. The literature on the subject lacks the confrontation of the results of scientific research in the field of environmental impact assessment of the BEV use phase with the knowledge of the public on this subject. The research results can be used by decision makers to properly target the support for the development of electromobility in Poland, consisting primarily in increasing the availability of infrastructure for charging BEV and changing the energy mix to energy sources with a lower environmental impact.
Financial networks of cryptocurrency prices in time-frequency domains

Published: June 2023

AbstractThis paper explores financial networks of cryptocurrency prices in both time and frequency domains. We complement the generalized forecast error variance decomposition method based on a large VAR model with network theory to analyze the dynamic network structure and the shock propagation mechanisms across a set of 40 cryptocurrency prices. Results show that the evolving network topology of spillovers in both time and frequency domains helps towards a more comprehensive understanding of the interactions among cryptocurrencies, and that overall spillovers in the cryptocurrency market have significantly increased in the aftermath of COVID-19. Our findings indicate that a significant portion of these spillovers dissipate in the short-run (1–5 days), highlighting the need to consider the frequency persistence of shocks in the network for effective risk management at different target horizons.

Public–Private Collusion
Authors: Mota Filipa , Correia-da-Silva João , Pinho Joana 
Published: June 2023

AbstractWe study collusion between a public firm and a private firm facing linear demand and quadratic costs. We characterize the collusive outcome that results from Nash bargaining and compare it to the non-cooperative outcome. If the public firm’s taste for consumer surplus is mild, both firms reduce output (as in a private duopoly). If it is intermediate, while the public firm reduces output, the private firm expands output to such an extent that total output increases. If it is strong, the private firm’s output expansion does not compensate for the public firm’s output contraction, and thus total output decreases. We also characterize collusion sustainability, and assess the impact of relative bargaining power, degree of cost convexity, public firm’s taste for total surplus, and cost asymmetry. We conclude that, by reducing the productive inefficiency that is caused by the public firm being more expansionary, collusion may lead to higher profits and consumer surplus.
Caligid sea lice (Copepoda: Caligidae) from golden snapper Lutjanus johnii (Bloch) in Australian waters, with the recognition of Sinocaligus Shen, 1957 as a junior synonym of Caligus Müller, 1785
Authors: Boxshall Geoff , Barton Diane P. 
Published: June 2023

AbstractTwo species of sea lice are reported from the golden snapper Lutjanus johnii (Bloch) in Australian waters. One was represented by chalimus larvae, adult males and extremely slender females in which the genital complex is scarcely wider than the fourth pedigerous somite. These females are adult as they carry paired spermatophores and are identified as Caligus dussumieri Rangnekar, 1957 on the details of their appendages. Caligus dussumieri was formerly placed in the genus Sinocaligus Shen, 1957 but the characters supporting the validity of this genus are not robust, so it is here proposed to treat it as a junior subjective synonym of Caligus and transfer its species as: Caligus formicoides Redkar, Rangnekar & Murti, 1949, Caligus dussumieri Shen, 1957, Caligus caudatus (Gnanamuthu, 1950) new combination and Caligus timorensis (Izawa, 1995) new combination. All these species can be placed in the C. bonito-species group within Caligus. Caligus rivulatus Pilla, Vankara & Chikkam, 2012 is recognized as a junior subjective synonym of C. dussumieri. A new species, C. auriolusn. sp. is also described and this is placed in the C. diaphanus species-group. A key to species of this species-group is provided which indicates that C. auriolusn. sp. is most closely related to C. stromatei Krøyer, 1863 but the latter can be distinguished by the slender abdomen of the female and by the more complex myxal process on the maxilliped in the male.

AbstractHydrodeoxygenation (HDO) of isoeugenol was carried out at 200 °C and 30 bar of H2 in a batch reactor using a series of bifunctional catalysts consisting of platinum supported on zeolite H-Beta-25 or H-Beta-300 and Bindzil as a binder. The purpose of the matrix was to understand the effect of the binder on the reaction, emulating the components of industrial catalysts and therefore facilitating catalyst scale-up. The effect of the supports acid strength, the location of metal nanoparticles, and their proximity to acid sites was also studied. The catalysts were characterized by N2 physisorption, inductively coupled plasma atomic emission spectrometry, Fourier transform infrared spectroscopy of adsorbed pyridine and scanning and transmission electron microscopy. It was found that platinum supported only on the zeolite was more active compared to platinum located on the binder. High levels of isoeugenol conversion (ca. 100%), propylcyclohexane yield (56%) and the liquid-phase mass balance (68%) were obtained for the catalyst consisting of Pt supported on both zeolite H-Beta-25 and Bindzil.
