Biochemical analysis of the life stages of Oecophylla smaragdina (weaver ant)
Authors: Kumre Sunanda B. 
Published: June 2024

The Asian weaver ant, Oecophylla smaragdina, indeed exhibits fascinating social behavior and a unique nesting strategy. The nesting behavior of weaver ants involves a "leaf-weaving," process where the worker ants use the silk produced by their larvae to bind leaves together, creating a complex and sturdy nest structure. Regarding their life stages and metabolic changes, Oecophylla smaragdina as a holometabolous species undergoes complete metamorphosis, involving distinct developmental stages such as egg, larva, pupa, and adult. Each stage is characterized by significant changes in the insect's physiology and appearance. It is essential to study the metabolic changes in these ants during their life stages to better understand their development, behavior, and adaptability to their environment. The main objective of the present study is a biochemical analysis of the life stages of the weaver ant. During this study, various ants were collected at various stages and analyzed for the estimation of protein, carbohydrate, RNA, and DNA. According to the findings, the concentration of proteins was observed to be highest during all life stages of weaver ants. Following proteins, the concentration of RNA was noted to be the highest, then the concentration of DNA and carbohydrates. It was also noted that the concentration of biomolecules increased from the egg stage to the pupal stage, reaching its maximum level at the pupal stage. However, after reaching the maximum level at the pupal stage, the concentration of biomolecules declines as the ant progresses from the white imago to the adult stage.

The paper compares Péter Olty’s translations of Gerard Manley Hopkins’s poetry with a selection published in the Lyra Mundi series by Európa Kiadó in 1985. Olty’s newly published collection, Istenáram (Kalligram, 2023) strives to preserve the particularities of Hopkins’s enigmatic and eccentric language. These include, among other things, sprung rhythm and consonant chiming, a vocabulary rich in neologisms, archaisms, and dialect words, and a stretching of grammatical conventions. These attributes make Hopkins’s poetry unique, highly enjoyable, and also challenging for readers. Whereas the translators of the Lyra Mundi selection toned down the peculiar language of the originals in favor of readability, Olty’s translations retain Hopkins’s distinctive style.

Diagnosing the Particle Transport Mechanism in the Pulsar Halo via X-Ray Observations

Published: June 2024

Abstract
Pulsar halos (also termed “TeV halos”) are a new class of γ-ray sources in the Galaxy, which manifest as extended γ-ray emission around middle-aged pulsars, as discovered around the Geminga pulsar, the Monogem pulsar, and PSR J0622+3749 by the High-Altitude Water Cherenkov Observatory and the Large High-Altitude Air Shower Observatory. A consensus has been reached that the teraelectronvolt emission comes from the inverse Compton scattering of escaping electrons/positrons from the pulsar wind nebula of the soft background radiation field, while the particle transport mechanism in the halo is still in dispute. Currently, there are mainly three interpretations: the isotropic, suppressed diffusion model; the isotropic, unsuppressed diffusion model that considers the ballistic propagation of newly injected particles; and the anisotropic diffusion model. While the predicted γ-ray surface brightness profiles of all three models can be more or less consistent with the observations, the implications of the three models for cosmic-ray transport mechanisms and the properties of the interstellar magnetic field are quite different. In this study, we calculate the anticipated X-ray emission of pulsar halos under the three models. We show that the synchrotron radiation of these escaping electrons/positrons can produce a corresponding X-ray halo around the pulsar and that the expected surface brightness profiles are distinct in the three models. We suggest that sensitive X-ray detectors of a large field of view (such as eROSITA and the Einstein Probe) with a reasonably long exposure time are crucial to understanding the formation mechanism of pulsar halos and can serve as a probe of the properties of interstellar turbulence.
Wind Roche-lobe Overflow in Low-mass Binaries: Exploring the Origin of Rapidly Rotating Blue Lurkers

Published: June 2024

Abstract
Wind Roche-lobe overflow (WRLOF) is a mass-transfer mechanism proposed by Mohamed and Podsiadlowski for stellar binaries wherein the wind acceleration zone of the donor star exceeds its Roche-lobe radius, allowing stellar wind material to be transferred to the accretor at enhanced rates. WRLOF may explain characteristics observed in blue lurkers and blue stragglers. While WRLOF has been implemented in rapid population synthesis codes, it has yet to be explored thoroughly in detailed binary models such as MESA (a 1D stellar evolution code), and over a wide range of initial binary configurations. We incorporate WRLOF accretion in MESA to investigate wide low-mass binaries at solar metallicity. We perform a parameter study over the initial orbital periods and stellar masses. In most of the models where we consider angular momentum transfer during accretion, the accretor is spun up to the critical (or breakup) rotation rate. Then we assume the star develops a boosted wind to efficiently reduce the angular momentum so that it could maintain subcritical rotation. Balanced by boosted wind loss, the accretor only gains ∼2% of its total mass, but can maintain a near-critical rotation rate during WRLOF. Notably, the mass-transfer efficiency is significantly smaller than in previous studies in which the rotation of the accretor is ignored. We compare our results to observational data of blue lurkers in M67 and find that the WRLOF mechanism can qualitatively explain the origin of their rapid rotation, their location on the H-R diagram, and their orbital periods.
Cross-correlation Techniques to Mitigate the Interloper Contamination for Line Intensity Mapping Experiments
Authors: Roy Anirban , Battaglia Nicholas 
Published: June 2024

Abstract
Line intensity mapping (LIM) serves as a potent probe in astrophysics, relying on the statistical analysis of integrated spectral line emissions originating from distant star-forming galaxies. While LIM observations hold the promise of achieving a broad spectrum of scientific objectives, a significant hurdle for future experiments lies in distinguishing the targeted spectral line emitted at a specific redshift from undesired line emissions originating at different redshifts. The presence of these interloping lines poses a challenge to the accuracy of cosmological analyses. In this study, we introduce a novel approach to quantify line–line cross-correlations (LIM-LLX), enabling us to investigate the target signal amid instrumental noise and interloping emissions. For example, at a redshift of z ∼ 3.7, we observed that the measured auto-power spectrum of C ii 158 exhibited substantial bias, from interloping line emission. However, cross-correlating C ii 158 with CO(6–5) lines using an FYST-like experiment yielded a promising result, with a signal-to-noise ratio of ∼10. This measurement is notably unbiased. Additionally, we explore the extensive capabilities of cross-correlation by leveraging various CO transitions to probe the tomographic Universe at lower redshifts through LIM-LLX. We further demonstrate that incorporating low-frequency channels, such as 90 and 150 GHz, into FYST’s EoR-Spec-like experiment can maximize the potential for cross-correlation studies, effectively reducing the bias introduced by instrumental noise and interlopers.
Fits for the Convective Envelope Mass in Massive Stars
Authors: Picker Lewis , Hirai 平井 Ryosuke 遼介 , Mandel Ilya 
Published: June 2024

Abstract
We explore the evolution of massive stars (>8 M
⊙) with 1D models and present analytical fits to the masses and binding energies of the convective portions of their envelopes. These fits are given as functions of total mass, metallicity, and surface temperature (used as a proxy for evolutionary phase). They enable the application of the two-stage common envelope (CE) formalism in rapid binary population synthesis frameworks. We estimate that the degree of orbital hardening following CE ejection spans 6 orders of magnitude and is a very strong function of the accretor mass, and, to a lesser extent, donor evolutionary phase.

Amongst the major causes of deaths worldwide today, is diabetes mellitus. This ailment is frequently associated with a person's eating habits and heredity, and its recurrence rate is becoming seriously alarming. There are several anti-diabetic or hypoglycemic medications available for the treatment of the condition, but they are frequently expensive, out of reach for the poor, and frequently have unfavorable side effects. This highlights the need for scientific research to identify a different, safe, and efficient herbal drug that will be widely available, simple to use, and reasonably affordable for the treatment of the condition. In this study, the effects of Momordica balsamina aqueous methanolic extracts were investigated on albino rats induced with diabetes using alloxan. Albino rats weighing 150g and above and kept in the same condition with unrestricted access to food and water were used throughout the experiment. A solution of alloxan monohydrate was made by dissolving 0.9 mg in 6 mL of distilled water and the rats were given a single intraperitoneal injection of alloxan monohydrate (150 mg/kg). The blood glucose level of the rats was assessed both before and after alloxan diabetes induction and after treated with 50, 100 and 200 mg/kg of the aqueous methanolic extract of M. balsamina using a glucometer. The data obtained were subjected to statistical analysis at P-value (P 0.05 and 0.01) using Pearson correlation analysis. The work conducted on albino rats indicated a substantial reduction in blood glucose levels after administering doses of 200 mg/kg body weight of M. balsamin aqueous methanolic extract. This effect was particularly notable between the third and thirty third days of the research period where a decreased in blood glucose level from 28.5±0.8 to 10.8±0.2, 8.3±1.1, 8.0±0.0, and 7.2±0.0 (mmol/L) in the third, sixth, ninth and twelfths days were observed respective, which also increased to 8.8±1.1 and 9.3±1.3 (mmol/L) in the fifteenth and eighteenth day, but continue decreasing throughout until become 7.4±1.5 (mmol/L) at thirty third day. It is worth mentioning that the test animals remained healthy and exhibited normal activity throughout the study. Furthermore, the LD50 test detected no indications of toxicity, suggesting the extract's relative safety. These findings strongly suggest that M. balsamina contains phytochemicals with potent anti-diabetic properties.

Published: June 2024

Numerous tourist destinations in Nigeria with a variety of attractions have failed to achieve their tourism capacities due to lack of strategic development to stimulate economic growth in the host communities and the nation at large. This study therefore evaluates the potential of developing Zuma Rock as a tourism Destination and the prospects for national economic growth of Nigeria. The data for this study was generated from primary and secondary sources. Observation and interview techniques were employed in which 35 respondents comprising head district, hotel employees and community residents were interviewed. Responses articulated were analyzed using Destination Competitive Tourism Model. The finding reveals that Zuma Rock qualifies to be a Tourism destination; therefore if it is fully developed it will contribute significantly to the economic growth of Nigeria through job creation, income generation by the host community, foreign exchange earnings and revenue to government. It has been recommended that government should intensified efforts in providing social amenities, tight security surveillance to curtail the menace of kidnapping and armed robbery in the area. Private participation in the areas of investment and destination promotion should be encouraged to fully harness the potentialities of Zuma Rock as a viable tourism destination.

Electromagnetic radiation (EMR) has both ionizable and non-ionizable chemical impact that causes protons and electrons to interact as fields in any surrounding as it travels. This can have negative health effects, such as warming up the body because of polarization and dipolar moment itchy skin eruption. This paper adopted Feynman diagram from quantum electrodynamics as a theoretical model to explain the quantum properties related to the interactions of EMR, in specific the exchanges involving photons and electrons in the 5G electromagnetic carrier signals. The Feynman model depicts electron-positron collisions as mutually annihilating antiparticles that ultimately produce photons. The mutual annihilation resulted in the disappearance of an electron and its antiparticle, producing gamma rays with highest ionizable penetrating power. The process of chemical polarization, also known as ionizing radiation, causes molecules within cells to split apart and create free reactive radicals, which in turn affects the immune system of the body. As a result of the existence of unpaired electrons that occurred from the breaking up of water molecules within the cells, it destabilizes the equilibrium of the charged particles that make up the human deoxyribonucleic acid (DNA). The free radicals will produce hydrogen peroxide compounds, which will start toxic chemical processes inside the cells that can lead to things like fluid accumulation in the lungs (pulmonary edema). Hydrogen peroxide produced from the disintegration of water molecules as a result of EMR is found to facilitate the multistage carcinogenic process, which involves carcinogen activation, oxidative DNA damage, and tumor formation.
