Abstract
During the past decade, the use of predatory mirids alone or combined with releases of egg parasitoids of the genus Trichogramma have been tested in Europe for biological control of the worldwide invasive pest, Tuta absoluta (Meyrick). Here, we evaluated the control of this pest by the release of the Neotropical mirid Macrolophus basicornis (Stal), the Neotropic/Nearctic parasitoid Trichogramma pretiosum Riley, and by combined releases of the predator and the parasitoid. Tests were conducted in greenhouse compartments during the summer and fall season. Each compartment contained 10 tomato plants in which only the pest was released or the pest with 1 or 2 natural enemies. Plant damage, and pest and natural enemy densities were checked weekly on one apical, medium, and bottom leaf of 5 plants. Both M. basicornis and T. pretiosum significantly reduced T. absoluta density when released alone. Combined releases resulted in a 10% higher reduction during the summer season, but not during the fall season. The damage caused by T. absoluta was significantly higher in control treatments than in all natural enemy treatments: at the end of the summer trial leaves were completely damaged in the control treatment, whereas only up to 25% leaf damage occurred in the natural enemy treatments. Combined releases did not result in lower damage than with releases of either M. basicornis or T. pretiosum. Practical aspects of single and combined releases are discussed.

Abstract
The efficacy of an existing cold disinfestation postharvest treatment targeting Ceratitis capitata (Wiedemann) in citrus was determined for the marula fly, Ceratitis cosyra (Walker). The cold tolerances of C. capitata and C. cosyra were first quantified in artificial diet at 3.5 °C at different exposure periods for up to 18 days. Ceratitis capitata was found to be more cold tolerant than C. cosyra. At 3.5 °C, the duration to achieve 99.9968% mortality was calculated to be 11.57 days for C. capitata and 9.10 days for C. cosyra. Under an existing C. capitata cold treatment schedule at 1 °C for 14 days, the conditions required for complete mortality of the third larval stage of C. cosyra in orange, Citrus sinensis (L.) Osbeck cv. Valencia, were then determined. No survivors of C. cosyra in oranges were recorded beyond 11 days of cold treatment at 1 °C. The efficacy of this C. capitata treatment for disinfestation of C. cosyra was thereafter confirmed in large scale trials in Valencia oranges. In the large-scale trial at the lowest mean temperature of 1.19 °C for 14 days, there were no survivors from a total of 85 490 treated C. cosyra third instars in oranges. Since C. capitata was shown to be more cold tolerant than C. cosyra and a large scale test demonstrated at least 99.9965% efficacy after 14 days at 1.19 °C, compared with the established effective C. capitata cold treatment of 14 days at 1.11 °C, cold disinfestation treatments for C. capitata should be at least equally effective against C. cosyra.
What drives organizational missions in the nonprofit sector? An institutional logic dependence perspective
Authors: Hwang Hyunseok , Lee Young-joo 
Published: April 2023

AbstractThis study examines how institutional multiplicity shapes nonprofit organizations’ mission-oriented actions by using the institutional logics perspective. We test how different institutional logics (professional, market, state, and community logics) independently and collectively affect mission-oriented actions of nonprofit organizations, focusing on the two focal subsectors: human service organizations and art and culture organizations. Using a panel dataset of 501(c)(3) nonprofit organizations between 2000 and 2010, we find that multiple institutional logics jointly as well as independently affect nonprofits’ mission-oriented actions and this relationship varies between the two subsectors. The findings offer empirical evidence of how multiple logics co-exist and how the dynamics among multiple logics may shape nonprofits’ actions across different subsectors.
‘Circumstances Sufficiently Appalling to the Country People’: Suicide Burial in Thomas Hardy’s ‘The Grave by the Handpost’
Authors: Dillion Jacqueline 
Published: April 2023

Abstract
Thomas Hardy’s 1897 short story, ‘The Grave By the Handpost,’ set in early nineteenth-century Dorset, explores the custom of suicide burial at the crossroads before the practice was outlawed in 1823. The story, which draws from family history, local accounts, and articles in the Dorset County Chronicle, tells of a widowed sergeant who feels forsaken by his son, and in a state of despair, takes his life. The coroner rules a felo de se (or ‘felon of himself’), and the sergeant’s body is buried at the parish boundary between two villages. In contrast with other customs, suicide burial was characterized by a unique capacity to shame both the deceased and the deceased’s family in perpetuity. While suicide itself would not be decriminalized until 1961, I argue that Hardy sought to destigmatize the coupling of suicide and shame that had predominated in British culture for centuries. This approach follows from Thomas Hardy: Folklore and Resistance (2016) in reading Hardy’s view of folk culture in flux, as rural communities evolved to reimagine their inherited customs. Hardy espoused what he called ‘evolutionary meliorism’, a belief that communities might develop more ethical responses to human situations than were codified in the law. I argue that the villagers’ response in ‘The Grave’ demonstrates this idea in practice, and I conclude that their decision to reject this custom on ethical grounds marks ‘The Grave’ as an important late Hardy work.
Dehydrozingerone enhances the fungicidal activity of glabridin againstSaccharomyces cerevisiaeandCandida albicans

AbstractDrug resistance commonly occurs when treating immunocompromized patients with fungal infections. Dehydrozingerone—a phenolic compound isolated from the rhizome of Zingiber officinale—inhibits drug efflux in Saccharomyces cerevisiae by overexpression of the ATP-binding cassette (ABC) transporter Pdr5p. We aimed to investigate whether dehydrozingerone enhances the antifungal activity of glabridin—an isoflavan isolated from the roots of Glycyrrhiza glabra L.—by attenuating multidrug resistance through the intrinsic expression system of multidrug-efflux-related genes in a wild-type strain of the model yeast. The antifungal activity of 50 μmol l−1 glabridin alone was weak and temporary against S. cerevisiae; however, cell viability was significantly inhibited when the cells were co-treated with glabridin and dehydrozingerone. This enhancement was also observed in human pathogenic Candida albicans. Glabridin efflux did not depend on a particular drug efflux pump; instead, the transcription factors PDR1 and PDR3—regulating the transcription of multiple genes encoding drug efflux pumps—were involved in the antifungal activity and efflux of glabridin. qRT–PCR analysis revealed that dehydrozingerone reduced glabridin-induced overexpression of the ABC transporter-related genes PDR1, PDR3, and PDR5 to the levels observed in untreated cells. Our findings indicated that dehydrozingerone potentiates the efficacy of plant-derived antifungals through its effects on ABC transporters.
Hacking stylometry with multiple voices: Imaginary writers can override authorial signal in Delta
Authors: Skorinkin Daniil , Orekhov Boris 
Published: April 2023

Abstract
It is a basic assumption of stylometry that texts written by the same person show greater stylometric similarity even if published under multiple pennames. Statistical authorship attribution strongly relies on the ability of Burrows’s Delta and its variants to cluster one author together regardless of pseudonyms. At the same time, the very first computational discoveries by the founder of modern stylometry showed that a single author is capable of producing multiple voices (Burrows, 1987, Computation into Criticism: A Study of Jane Austen’s Novels and an Experiment in Method. Clarendon Press). We investigate two authors whose stylistically autonomous pennames seem to deceive Delta and override authorial signals: a Portuguese poet Fernando Pessoa and a French novelist Romain Gary. Pessoa managed to create at least three pennames (the author himself used the term ‘heteronym’) who exhibit all traits of individual human beings from the stylometric point of view. Gary’s alter ego Emile Ajar, who was an intentional literary mystification, also demonstrates traits of stylometric autonomy. At the same time, other pseudonyms used by Gary lack that autonomy completely. Our investigation shows that there appears to be a continuum between a purely formal use of a penname, which brings almost no distinction from the real name of an author, and a strong literary sub-personality such as those created by Pessoa.

AbstractPneumocystis pneumonia (PCP) is the most frequent fungal opportunistic infection defining AIDS in HIV-infected patients, and is of growing importance in HIV-negative patients. In this latter category of patients, the diagnosis mainly relies on real-time polymerase chain reaction (qPCR) detection of Pneumocystis jirovecii (Pj) on respiratory samples. The PneumoGenius® kit (PathoNostics) allows the simultaneous detection of Pj mitochondrial large subunit (mtLSU) and dihydropteroate synthase (DHPS) polymorphisms, which could be of interest to anticipate therapeutic failure. This study aimed at evaluating its clinical performance on 251 respiratory specimens (239 patients), (i) for P. jirovecii detection in clinical samples, and (ii) for DHPS polymorphisms detection in circulating strains.Patients were classified according to modified European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group (EORTC/MSG) criteria, as having proven PCP (n = 62), probable PCP (n = 87), Pneumocystis colonization (n = 37), and no PCP (n = 53).Compared with in-house qPCR, the sensitivity of PneumoGenius® assay for P. jirovecii detection reached 91.9% (182/198), the specificity was excellent (100%, 53/53) and the global concordance was 93.6% (235/253). A total of four diagnoses of proven/probable PCP were missed by the PneumoGenius® assay, reaching a 97.5% sensitivity (157/161) in this sub-group. The 12 other ‘false–negative’ results were obtained in patients diagnosed as colonized using the in-house PCR. DHPS genotyping was successful for 147/182 samples with PneumoGenius® and revealed dhps mutation in 8 samples, which were all confirmed by sequencing.In conclusion, PneumoGenius® assay missed the detection of low-burden PCP. This lower sensitivity for PCP diagnosis can be balanced by a higher specificity (P. jirovecii colonization less frequently detected) and the efficient detection of DHPS hot spot mutations.
The Hamiltonian for von Zeipel–Lidov–Kozai oscillations
Authors: Tremaine Scott 
Published: April 2023

ABSTRACTThe Hamiltonian used in classical analyses of von Zeipel–Lidov–Kozai or ZLK oscillations in hierarchical triple systems is based on the quadrupole potential from a distant body on a fixed orbit, averaged over the orbits of both the inner and the outer bodies (‘double averaging’). This approximation can be misleading, because the corresponding Hamiltonian conserves the component of angular momentum of the inner binary normal to the orbit of the outer binary, thereby restricting the volume of phase space that the system can access. This defect is usually remedied by including the effects of the octopole potential, or by allowing the outer orbit to respond to variations in the inner orbit. However, in a wide variety of astrophysical systems, non-linear perturbations are comparable to or greater than these effects. The long-term effects of non-linear perturbations are described by an additional Hamiltonian, which we call Brown’s Hamiltonian. At least three different forms of Brown’s Hamiltonian are found in the literature; we show that all three are related by a gauge freedom, although one is much simpler than the others. We argue that investigations of ZLK oscillations in triple systems should include Brown’s Hamiltonian.
Identifying and characterizing ultracool dwarfs ejected from post-encounter disintegrating systems

Published: April 2023

ABSTRACT
Disintegrating multiple systems have been previously discovered from kinematic studies of the Hipparcos catalogue. They are presumably the result of dynamical encounters taking place in the Galactic disc between single/multiple systems. In this paper, we aim to expand the search for such systems, to study their properties, as well as to characterize possible low-mass ejecta (i.e. brown dwarfs and planets). We have assembled a list of 15 candidate systems using astrometry from the Tycho-Gaia astrometric solution (later upgraded with Gaia DR3), and here we present the discovery and follow-up of five of them. We have obtained DECam imaging for all five systems and by combining near-infrared photometry and proper motion, we searched for ultracool ejected components. We find that the system consisting of TYC 7731-1951-1, TYC 7731-2128 AB, and TYC 7731-1995-1ABC?, contains one very promising ultracool dwarf candidate. Using additional data from the literature, we have found that three out of five disintegrating system candidates are likely to be true disintegrating systems.
Likelihood of Martian moons as dust sources in light with Juno observations
Authors: Pabari J P 
Published: April 2023

ABSTRACT
Juno observations show dust halo near Mars, contributing to Zodiacal light, the source of which is yet to be known. It is interesting for scientists to understand whether dust primarily comes from the Martian moons. Here, we investigate Phobos/Deimos as likely sources of interplanetary dust near Mars. Incoming dust at the Martian moons impact their surface and produce ejecta, a part of which can escape easily to space. Results of escaping mass rates are presented and compared with incoming mass rates through a parameter called mass escape ratio. The results show higher ratio for a wide range of particles, inferring a large amount of effective mass loss from the moons. From whatever is lost, smaller particles (&lt;0.1 µm) can escape, while larger particles are influenced by the gravitational pull of Mars. Furthermore, from the larger particles, those with sizes greater than critical size (i.e. ∼10 µm) remain in a ring/torus for a specific lifetime and afterwards, they get released from the gravitational effect of Mars. Since, incoming dust creates the ejecta continuously from Phobos/Deimos, the process of the release of particles after the lifetime is also continuous. On the other side, flux of interplanetary dust is derived from Juno observations of dust impact rates between 1 and 5 au heliocentric distance. An increase in the flux observed by Juno around 1.5 au and the results of larger, continuous escaping mass from the moons indicate Phobos and Deimos to be the local sources of dust bands observed by Juno spacecraft.

ABSTRACTWe present optimized physical parameters of the active eclipsing binary system USNO-B1.0 1387-0467554 discovered recently in Yunnan–Hong Kong wide-field photometric (YNHK) survey, based on the analysis of its two colour light curves and low resolution spectra obtained at Yunnan Observatories, China. Its spot distributions are derived by means of the Wilson–Devinney code, using photometric data of the YNHK survey from 2016 to 2021. There exist active longitude belts for the spot activities on the primary star, for which the effect of tidal force seems dominant comparing with the one of common magnetic field of the binary system. We have investigated its chromospheric activities through the indicators including Hα, Hβ, CaII H&K, and HeI D3 lines covered by the low resolution spectroscopic observations. There are obvious spatial correlations between the magnetic activities in its photosphere and chromosphere. The EHα/EHβ values suggest that both plages and prominences led to the emissions seen in the Balmer lines at most phases. A prominence structure appeared around the phase of 0.8 on 2018 October 25 and evolved in November and December, 2018. The spectra demonstrate that there were frequent flare events in the system. Moreover, the decay part of a white-light flare event was hunted by the YNHK survey on 2021 October 26.
Origin and evolution of ultradiffuse galaxies in different environments

Published: April 2023

ABSTRACT
We study the formation of ultradiffuse galaxies (UDGs) using the cosmological hydrodynamical simulation TNG50 of the Illustris-TNG suite. We define UDGs as dwarf galaxies in the stellar mass range $\rm {7.5 \le log (M_{\star } / {\rm M}_{\odot }) \le 9 }$ that are in the 5 per cent most extended tail of the simulated mass–size relation. This results in a sample of UDGs with half-mass radii $\rm {r_{h \star } \gtrsim 2 \ kpc}$ and surface brightness between $\rm {24.5}$ and $\rm {28 \ mag \ arcsec^{-2}}$, similar to definitions of UDGs in observations. The large cosmological volume in TNG50 allows for a comparison of UDGs properties in different environments, from the field to galaxy clusters with virial mass $\rm {M_{200} \sim 2 \times 10^{14} ~ {\rm M}_{\odot }}$. All UDGs in our sample have dwarf-mass haloes ($\rm {M_{200}\sim 10^{11} ~ {\rm M}_{\odot } }$) and show the same environmental trends as normal dwarfs: field UDGs are star-forming and blue while satellite UDGs are typically quiescent and red. The TNG50 simulation predicts UDGs that populate preferentially higher spin haloes and more massive haloes at fixed $\rm {M_{\star }}$ compared to non-UDG dwarfs. This applies also to most satellite UDGs, which are actually ‘born’ UDGs in the field and infall into groups and clusters without significant changes to their size. We find, however, a small subset of satellite UDGs ($\lesssim 10~{{\ \rm per\ cent}}$) with present-day stellar size a factor ≥1.5 larger than at infall, confirming that tidal effects, particularly in the lower mass dwarfs, are also a viable formation mechanism for some of these dwarfs, although sub-dominant in this simulation.
Modelling dark matter halo spin using observations and simulations: application to UGC 5288
Authors: Ansar Sioree , Kataria Sandeep Kumar , Das Mousumi 
Published: April 2023

ABSTRACT
Dark matter (DM) halo properties are extensively studied in cosmological simulations but are very challenging to estimate from observations. The DM halo density profile of observed galaxies is modelled using multiple probes that trace the DM potential. However, the angular momentum distribution of DM halos is still a subject of debate. In this study, we investigate a method for estimating the halo spin and halo concentration of low surface brightness (LSB), gas-rich dwarf barred galaxy UGC 5288, by forward modelling disc properties derived from observations – stellar and gas surface densities, disc scalelength, H i rotation curve, bar length, and bar ellipticity. We combine semi-analytical techniques, N-body/SPH, and cosmological simulations to model the DM halo of UGC 5288 with both a cuspy Hernquist profile and a flat-core pseudo-isothermal profile. We find that the best match with observations is a pseudo-isothermal halo model with a core radius of rc = 0.23 kpc and halo spin of λ = 0.08 at the virial radius. Although our findings are consistent with previous core radius estimates of the halo density profile of UGC 5288, as well as with the halo spin profiles of similar mass analogues of UGC 5288 in the high-resolution cosmological-magneto-hydrodynamical simulation TNG50, there still remain some uncertainties as we are limited in our knowledge of the formation history of the galaxy. Additionally, we find that the inner halo spin (r &lt; 10 kpc) in barred galaxies is different from the unbarred ones, and the halo spin shows weak correlations with bar properties.
A novel approach to correcting Te-based mass–metallicity relations
Authors: Cameron Alex J , Katz Harley , Rey Martin P 
Published: April 2023

ABSTRACT
Deriving oxygen abundances from the electron temperature (hereafter the Te method) is the gold standard for extragalactic metallicity studies. However, unresolved temperature fluctuations within individual H ii regions and across different H ii regions throughout a galaxy can bias metallicity estimates low, with a magnitude that depends on the underlying and typically unknown temperature distribution. Using a toy model, we confirm that computing Te-based metallicities using the temperature derived from the [O iii] λ4363/λ5007 or [O ii] λλ7320, 7330/[O ii] λλ3727 ratio (‘ratio temperature’, Tratio) results in an underprediction of metallicity when temperature fluctuations are present. In contrast, using the unobservable ‘line temperatures’ (Tline) that provide the mean electron and ion density-weighted emissivity yields an accurate metallicity estimate. To correct this bias in low-mass galaxies, we demonstrate an example calibration of a relation between Tratio and Tline based on a high-resolution (4.5 pc) ramses-rtz simulation of a dwarf galaxy that self-consistently models the formation of multiple H ii regions and ion temperature distribution in a galactic context. Applying this correction to the low-mass end of the mass–metallicity relation shifts its normalization up by 0.18 dex on average and flattens its slope from 0.87 to 0.58, highlighting the need for future studies to account for, and correct, this bias.
