Farmers’ Knowledge and Perceptions in the Production of Coconut Rhinoceros Beetle (Oryctes rhinoceros) for Enhanced Food Security in Kenya
Authors: Ong’or Dennis Ouma , Orinda Mary Akinyi , Abel Benard Otieno
Published: January 2024

Local knowledge and perceptions regarding the value of edible insects among smallholder farmers are critical to introducing such enterprises and designing effective insect productivity-enhancing interventions. However, limited studies have been done in Kenya regarding insects as agricultural enterprises, specifically in the Kilifi region. A survey was carried out among 207 smallholder farmers of coconut palm in Kilifi North and South sub-counties to assess their knowledge and perceptions about Oryctes rhinoceros as a farm enterprise. The primary data was collected using a structured questionnaire triangulated by key informant interviews from the Department of Agriculture, Nuts and Oil Crop Directorate, and farmer group leaders. Descriptive statistics and a chi-square test were the major analyses. Results showed farmers had adequate knowledge and positive perceptions regarding the beetle and its useful larval stage, represented by the mean of 0.97 and 3.44, respectively. The age, education level, prior exposure to training on edible insect farming, religion, and years of coconut farming of the farmers are associated with the levels of knowledge and perceived values of the Oryctes rhinoceros farming. Considering the positive knowledge levels and perceptions among Kilifi farmers, rather than focusing on general awareness creation, there is a need to enhance the access to and use of agricultural training resources to learn the importance of agricultural innovations as a tool for food insecurity alleviation through intensive processes. The extension systems need to incorporate the concepts of edible insects. This will render an innovation sustainable and useful for economically disadvantaged people. Further studies should be done among livestock feed traders and even food and feed processors to enable effective commercialisation interventions
Necessary Conditions and Empirical Observations for Rearrangeable Banyan-Type Networks
Authors: Ohta Satoru
Published: January 2024

A banyan-type network is constructed by aligning unit switches with two inlets and outlets in multiple stages. Rearrangeable banyan-type networks are crucial for applications such as communication systems because they can universally establish connections for any request without blocking. If the number of network inputs (or outputs) is 2^n (n > 0), the banyan-type network should have 2n − 1 or more stages to be rearrangeable. A few rearrangeable 2n − 1 stage networks have been reported. However, the class of rearrangeable 2n − 1 stage banyan-type networks has not been completely clarified. This study examines the identification of rearrangeable 2n − 1 stage banyan-type networks that are not isomorphic to one another. This is done by generating candidate networks and checking their rearrangeability via the satisfiability problem. The drawback of this approach is its poor scalability due to numerous candidates. To eliminate this drawback, it is shown that the candidates can be reduced to a smaller number of networks called pure banyan networks. This is achieved by analyzing network isomorphism. Next, necessary conditions are derived for rearrangeability. Utilizing the conditions, the number of candidate networks further decreases because blocking networks are identified and removed from the candidates. For the reduced number of candidate networks, rearrangeability is assessed through computer experiments for n = 4 and 5. For n = 4, the result shows that any rearrangeable configuration is isomorphic to previously reported rearrangeable networks. For n = 5, the blocking probability is extremely low and the rearrangeability is inconclusive for two groups of networks.
Hepatocardiorenal syndrome in liver cirrhosis: Recognition of a new entity?
Authors: Wu Henry H L , Rakisheva Amina , Ponnusamy Arvind , Chinnadurai Rajkumar
Published: January 2024

Emerging evidence and perspectives have pointed towards the heart playing an important role in hepatorenal syndrome (HRS), outside of conventional understanding that liver cirrhosis is traditionally considered the sole origin of a cascade of pathophysiological mechanisms directly affecting the kidneys in this context. In the absence of established heart disease, cirrhotic cardiomyopathy may occur more frequently in those with liver cirrhosis and kidney disease. It is a specific form of cardiac dysfunction characterized by blunted contractile responsiveness to stress stimuli and altered diastolic relaxation with electrophysiological abnormalities. Despite the clinical description of these potential cardiac-related complications of the liver, the role of the heart has traditionally been an overlooked aspect of circulatory dysfunction in HRS. Yet from a physiological sense, temporality (prior onset) of cardiorenal interactions in HRS and positive effects stemming from portosystemic shunting demonstrated an important role of the heart in the development and progression of kidney dysfunction in cirrhotic patients. In this review, we discuss current concepts surrounding how the heart may influence the development and progression of HRS, and the role of systemic inflammation and endothelial dysfunction causing circulatory dysfunction within this setting. The temporality of heart and kidney dysfunction in HRS will be discussed. For a subgroup of patients who receive portosystemic shunting, the dynamics of cardiorenal interactions following treatment is reviewed. Continued research to determine the unknowns in this topic is anticipated, hopefully to further clarify the intricacies surrounding the liver-heart-kidney connection and improve strategies for management.

Published: January 2024

BACKGROUND

Tumor budding (TB) has emerged as a promising independent prognostic biomarker in colorectal cancer (CRC). The prognostic role of TB has been extensively studied and currently affects clinical decision making in patients with stage I and II CRC. However, existing prognostic studies on TB in stage III CRC have been confined to small retrospective cohort studies. Consequently, this study investigated the correlation among TB categories, clinicopathological features, and prognosis in stage III-IV CRC to further enhance the precision and individualization of treatment through refined prognostic risk stratification.

AIM

To analyze the relationship between TB categories and clinicopathological characteristics and assess their prognostic value in stage III-IV CRC to further refine the prognostic risk stratification of stage III-IV CRC.

METHODS

The clinical data of 547 CRC patients were collected for this retrospective study. Infiltration at the front edge of the tumor buds was counted according to the 2016 International Tumor Budding Consensus Conference guidelines.

RESULTS

Multivariate Cox proportional hazards regression analysis demonstrated that chemotherapy (P = 0.004), clinical stage IV (P < 0.001), ≥ 4 regional lymph node metastases (P = 0.004), left-sided colonic cancer (P = 0.040), and Bd 2-3 (P = 0.002) were independent prognostic factors in patients with stage III-IV CRC. Moreover, the density of tumor infiltrating lymphocytes was higher in Bd 1 than in Bd 2-3, both in the tumor stroma and its invasive margin.

CONCLUSION

TB has an independent predictive prognostic value in patients with stage III-IV CRC. It is recommended to complete the TB report of stage III-IV CRC cases in the standardized pathological report to further refine risk stratification.

Cancer patients are generally submitted to chemotherapy and radiotherapy, which tend to cause problems related to intense inflammatory processes, malnutrition, nausea, and emesis. Therefore, performing supplementation in these patients is important and necessary, as it favors cancer patients from a nutritional point of view. Amino acids and β-glucans obtained from fermentation processes proved to be important in the care of cancer patients because they improve the nutritional parameters and general condition of the patient. We aim to discuss the benefits obtained by cancer patients undergoing chemotherapy and radiotherapy who received supplementation with a fermented nutraceutical rich in β-glucans and amino acids. A literature review was carried out through an active search for scientific articles by the following descriptors in Portuguese: “nutraceutical”, “β-glucans”, “oncological patients”. In addition, we also discuss the benefits caused using the product called BionutriAR1®, a nutraceutical that contributes to the recovery of nutritional status. We conclude that the use of products capable of promoting supplementation of β-glucans and amino acids is beneficial to cancer patients, especially those undergoing chemotherapy and radiotherapy and, therefore, there is an indication of supplementation for these patients with the fermented product BionutriAR1®.
¿Requieren las especies ser monofiléticas?
Authors: Schmitter-Soto Juan Jacobo
Published: January 2024

A diferencia de los taxones superiores, las especies no requieren ser monofiléticas; por debajo de ese nivel no hay taxones, sino poblaciones e individuos, con relaciones no filogenéticas, sino tocogenéticas. La existencia de “paraespecies”, especies no originadas a partir de una única población, es previsible, sobre todo cuando la especiación ha sido de tipo peripátrico, con una población periférica que diverge rápidamente (por ejemplo, debido a una regresión marina que la deja aislada en un embalse epicontinental) y deja en situación parafilética al resto de poblaciones de la distribución original. El concepto evolutivo de especie, i.e. la especie como linaje, no necesariamente excluye a las paraespecies. El criterio de independencia y coherencia evolutiva puede cumplirse mediante una diagnosis consistente, en especial si proviene de un enfoque taxonómico integrativo, con datos moleculares, ecológicos, biogeográficos y morfológicos.

A Markedly Expanded Sample of Candidate X-Ray-emitting Isolated Neutron Stars
Authors: Demasi Sebastian , Anderson Scott F. , Agüeros Marcel A.
Published: January 2024

The current sample of 12 radio-quiet isolated neutron stars that emit strongly in X-rays (XINSs) is both small and heterogeneous, limiting its usefulness for understanding the physics of neutron star atmospheres and cooling rates and for constraining the equation of state of neutron degenerate matter. Utilizing the ROSAT 1RXS and 2RXS data sets, in conjunction with the Sloan Digital Sky Survey Data Release 17 and other companion multiwavelength surveys, we have extended previous searches for blank-field X-ray source candidate XINSs, ultimately recovering two known XINSs while identifying 46 new, unstudied candidate fields devoid of likely multiwavelength counterparts. In this publication, we describe our selection approach and provide detailed information regarding our sample of new candidate XINSs. Future opportunities to verify or to refute these X-ray sources as isolated neutron stars by obtaining more accurate X-ray source positions, quality X-ray spectra, or deeper optical imaging are also discussed.
Modeling Noncondensing Compositional Convection for Applications to Super-Earth and Sub-Neptune Atmospheres
Authors: Habib Namrah , Pierrehumbert Raymond T.
Published: January 2024

Compositional convection is atmospheric mixing driven by density variations caused by compositional gradients. Previous studies have suggested that compositional gradients of atmospheric trace species within planetary atmospheres can impact convection and the final atmospheric temperature profile. In this work, we employ 3D convection-resolving simulations using Cloud Model 1 (CM1) to gain a fundamental understanding of how compositional variation influences convection and the final atmospheric state of exoplanet atmospheres. We perform 3D initial value problem simulations of noncondensing compositional convection for Earth-air, H2, and CO2 atmospheres. Conventionally, atmospheric convection is assumed to mix the atmosphere to a final, marginally stable state defined by a unique temperature profile. However, when there is compositional variation within an atmosphere, a continuous family of stable end states is possible, differing in the final state composition profile. Our CM1 simulations are used to determine which of the family of possible compositional end states is selected. Leveraging the results from our CM1 simulations, we develop a dry convective adjustment scheme for use in general circulation models (GCMs). This scheme relies on an energy analysis to determine the final adjusted atmospheric state. Our convection scheme produces results that agree with our CM1 simulations and can easily be implemented in GCMs to improve modeling of compositional convection in exoplanet atmospheres.
Exploring the Circumstellar Environment of Tycho’s Supernova Remnant. I. The Hydrodynamic Evolution of the Shock
Authors: Kobashi Ryosuke , Lee Shiu-Hang , Tanaka Takaaki , Maeda Keiichi
Published: January 2024

Among Type Ia supernova remnants (SNRs), Tycho’s SNR has been considered as a typical object from the viewpoints of its spectroscopic, morphological, and environmental properties. A recent reanalysis of Chandra data showed that its forward shock is experiencing a substantial deceleration since around 2007, which suggests recent shock interactions with a dense medium as a consequence of a cavity-wall environment inside a molecular cloud. Such a nonuniform environment can be linked back to the nature and activities of its progenitor. In this study, we perform hydrodynamic simulations to characterize Tycho’s cavity-wall environment using the latest multiepoch proper motion measurements of the forward shock. A range of parameters for the environment is explored in the hydrodynamic models to fit with the observational data for each azimuthal region. Our results show that a wind-like cavity with ρ(r) ∝ r
−2 reconciles with the latest data better than a uniform medium with a constant density. In addition, our best-fit model favors an anisotropic wind with an azimuthally varying wind parameter. The overall result indicates a mass-loss rate which is unusually high for the conventional single-degenerate explosion scenario.
How Many Supermassive Black Hole Binaries Are Detectable through Tracking Relative Motions by (Sub)millimeter Very Long Baseline Interferometry?

The (sub)millimeter wavelengths (86–690 GHz) very long baseline interferometry will provide ∼5–40 μas angular resolution, ∼10 mJy baseline sensitivity, and ∼1 μas yr−1 proper-motion precision, which can directly detect supermassive black hole binary (SMBHB) systems by imaging the two visible sources and tracking their relative motions. Such a way exhibits an advantage compared to indirect detect methods of observing periodic signals in motion and light curves, which are difficult to confirm from competing models. Moreover, tracking relative motion at (sub)millimeter wavelengths is more reliable, as there is a negligible offset between the emission region and the black hole center. In this way, it is unnecessary to correct the black hole location by a prior of jet morphology as it would be required at longer wavelengths. We extend the formalism developed in D’Orazio & Loeb (2018) to link the observations with the orbital evolution of SMBHBs from the ≲10 kpc dynamical friction stages to the ≲0.01 pc gravitational radiation stages, and estimate the detectable numbers of SMBHBs. By assuming 5% of active galactic nuclei holding SMBHBs, we find that the number of detectable SMBHBs with redshift z ≤ 0.5 and mass M ≤ 1011
M
⊙ is about 20. Such a detection relies heavily on proper-motion precision and sensitivity. Furthermore, we propose that the simultaneous multifrequency technique plays a key role in meeting the observational requirements.

We present the first star formation history (SFH) and age–metallicity relation (AMR) derived from resolved stellar populations imaged with the JWST NIRCam instrument. The target is the Local Group star-forming galaxy WLM at 970 kpc. The depth of the color–magnitude diagram (CMD) reaches below the oldest main sequence turnoff with a signal-to-noise ratio = 10 at M
F090W = + 4.6 mag. This is the deepest CMD for any galaxy that is not a satellite of the Milky Way. We use Hubble Space Telescope (HST) optical imaging that overlaps with the NIRCam observations to directly evaluate the SFHs derived based on data from the two great observatories. The JWST and HST-based SFHs are in excellent agreement. We use the metallicity distribution function measured from stellar spectra to confirm the trends in the AMRs based on the JWST data. Together, these results confirm the efficacy of recovering an SFH and AMR with the NIRCam F090W−F150W filter combination, and validate the sensitivity and accuracy of stellar evolution libraries in the near-infrared relative to the optical for SFH recovery work. From the JWST data, WLM shows an early onset to star formation, followed by an extended pause post-reionization before star formation reignites, which is qualitatively similar to what has been observed in the isolated galaxies Leo A and Aquarius. Quantitatively, 15% of the stellar mass formed in the first Gyr, while only 10% formed over the next ∼5 Gyr. The stellar mass then rapidly doubled in ∼2.5 Gyr, followed by constant star formation over the last ∼5 Gyr.

Photometric observations of the eclipsing dwarf nova HT Cas are presented in its quiescent state on 2022 October 20th for one complete orbital period. These data were taken with the RISE imager mounted on the Liverpool Telescope. The lcurve code was used to fit the light curve. System parameters were derived of mass ratio q = M

Evaluation of a Magnetic Field Inversion Method Using Only Stokes I

Published: January 2024

We compare a method for inferring the photospheric vector magnetic field using only spectroscopy to a conventional method based on polarimetry. The magnetic field strength B and inclination angle can be inferred from the Zeeman splitting using only Stokes I. We applied this method to a sunspot observed with the Vacuum Tower Telescope and compared the results to vector magnetograms from the Helioseismic and Magnetic Imager on the Solar Dynamics Observatory, which used a polarimetric inversion. The spectroscopic inversion tends to show higher values in B compared to the polarimetric data. In quiet regions the discrepancy in B was typically a factor of two. In the strong sunspot fields, the differences averaged ≈22%. These discrepancies are significant, but comparable to those typically found among magnetograms from different instruments. Our results support the use of the spectroscopic inversion technique to provide a fast and reasonable estimate of B.

Host fungus confirmed for Pelecocera (Pelecocera) tricinta and Pelecocera (Chamaesyrphus) caledonica (Diptera, Syrphidae)
Authors: Ståhls Gunilla
Published: January 2024

MtDNA COI barcodes have frequently been used to associate an unknown life stage in insects with a known species. This study reports the discovery of hoverfly larvae in the fungal fruit bodies of Rhizopogon luteolus Fr. & Nordholm, 1817, and the identification of these as Pelecocera (Pelecocera) tricincta and Pelecocera (Chamaesyrphus) caledonica (Collin, 1940) (Diptera, Syrphidae), confirming for the first time mycophagy as feeding mode of the larvae of these Pelecocera species in the Western Palaearctic region. The species identity of some larvae was firstly resolved using mtDNA COI barcodes generated from the larvae and tree-based identification. Obtained puparia were reared into adult flies and produced the same two species. The morphological features of these mycophagous larvae are compared with those of other fungus feeding hoverfly species.
Coexistence of Oligocene toothed and baleen-assisted mysticetes in the northwestern Pacific

Published: January 2024

Oligocene mysticetes display an unparalleled diversity and morphological disparity in the evolutionary history of Mysticeti. However, their paleoecological aspects, such as the patterns of coexistence of different morphotypes, remain poorly explored. Here we describe an aetiocetid (toothed mysticete) from the Jinnobaru Formation (lower upper Oligocene, about 28 million years ago) of Umashima Island, Kitakyushu, Japan. Our description of a toothed mysticete from the Oligocene of Umashima exemplifies the coexistence of toothed and baleen-assisted mysticetes in the northwestern Pacific. Hopefully, new finds of Oligocene mysticetes will lead to a well-sampled dataset for analyzing this and other related paleoecological traits to understand the demise of “archaic” Oligocene mysticetes and the subsequent rise of the modern-looking baleen-bearing whales in Miocene times.
Déléguer pour mieux articuler
Authors: Malarmey Hélène
Published: January 2024

Le recours à un service prestataire est souvent motivé par la nécessité de déléguer une partie des tâches qui nous incombe. En prenant l’exemple de la garde des enfants sur le temps périscolaire, cet article montre que le recours à des agences prestataires, spécialisées dans la garde d’enfants, correspond moins à une diminution du travail domestique et parental qu’à sa transformation. Largement subventionnées par les pouvoirs publics depuis les années 1990, ces agences apparaissent comme une nouvelle façon de penser l’articulation des temps de vie pour les parents actifs de classes moyenne et supérieure. Alors que le travail domestique et parental est encore largement assigné aux mères, celles qui travaillent recourent aux services d’agences lorsqu’elles ne peuvent faire appel aux solidarités familiales. Elles investissent ce service tant comme un moyen de déléguer la garde des enfants et la salarisation des intervenantes, que comme un mode de garde dont elles peuvent moduler la forme dans le sens de leurs pratiques et de leurs valeurs éducatives. S’appuyant sur des observations réalisées en agence et des entretiens auprès de parents-clients, d’intervenantes et de responsables d’agences, cet article montre que les mères actives voient leur charge mentale et gestionnaire s’accroître puisque l’encadrement de la main-d’œuvre et l’organisation de la prestation leur reviennent.
