“You are not able to estimate the depth of my grief as to outrage of my all dear and saint things”: Anatoly Koni and Bolsheviks
Authors: Esakov Gennady A.
Published: February 2024

The Article discusses misinterpreted period in the life of one of the leading Russian lawyers, Anatoly Koni. After 1917, he stayed in Soviet Russia, and this fact is often viewed as his loyalty to the new Soviet authorities. Following his writings, public speeches and especially unknown letters to his friends and colleagues, the author disproves this view. Koni was highly critical to the new authority and waited for its dismissal. His position may well be described as е´migration intе´rieure.

The Truncated EM Method for Stochastic Differential Equations Driven by Fractional Brownian Motion
Authors: Wang Suxin , Iyang Le
Published: February 2024

We mainly focus on the numerical method of fractional Brownian motion in this paper. On the basis of the numerical method of general SDEs, an approximation scheme is obtained for the stochastic differential equations about fractional noise. And we get it by using the Lipschitz condition and combining with the truncation function f∆ and g∆. Furthermore, we also prove the moment boundedness and convergence of the solution by some lemma. At last, we apply this method to the Gilpin-Ayala model. The orbital image of the solution and the form of numerical solution are given. The error of solution also has been simulated by MATLAB.

The subspecies Erebia scoparia doii Nakahara, 1926 described from the Kuril Islands is one of the poorly studied taxa of butterflies. The images of the external morphology and the male genitalia of this taxon are not freely available to researchers that causes difficulties during ecological and biogeographic studies, as well as various environmental protection measures. In this paper, we present a redescription of Erebia scoparia doii Nakahara, 1926 and illustrate the male genitalia and the external morphology of both sexes based on the topotypes from Kunashir Island. Also, we provide DNA sequence data of this subspecies for the first time. In addition, Erebia scoparia expleta Churkin, 2005 syn. nov. is considered here as a junior synonym of the nominotypical subspecies.
Revealing the Impact of Critical Stellar Central Density on Galaxy Quenching through Cosmic Time
Authors: Xu Bingxiao , Peng Yingjie
Published: February 2024

In a previous work, we investigated the structural and environmental dependence on quenching in the nearby universe. In this work, we extend our investigations to higher redshifts by combining galaxies from the Sloan Digital Sky Survey and The FourStar Galaxy Evolution surveys. In low density, we find a characteristic Σ1 kpc above which the quenching is initiated as indicated by their population-averaged color.

shows only a weak mass dependency at all redshifts, which suggests that the internal quenching process is more related to the physics that acts in the central region of galaxies. In high density,

for galaxies at z > 1 is almost indistinguishable from their low-density counterparts. At z < 1,

in low density shows strong redshift evolution with ∼1 dex decrement from z = 2.5–0. It is likely that at a given stellar mass, the host halo is on average more massive and gas-rich at higher redshifts; hence, a higher level of integrated energy from a more massive black hole (BH) is required to quench. As the halo evolves from the cold to hot accretion phase at lower redshifts, the gas is shock-heated and becomes more vulnerable to the feedback processes from active galactic nucleus as predicted by theory. Meanwhile, angular momentum quenching also becomes more effective at low redshifts, which complements a lower level of integrated energy from the BH to quench.
Magnetohydrodynamic Poynting Flux Vortices in the Solar Atmosphere and Their Role in Concentrating Energy

Published: February 2024

The nature of energy generation, transport, and effective dissipation responsible for maintaining a hot solar upper atmosphere is still elusive. The Poynting flux is a vital parameter for describing the direction and magnitude of the energy flow, which is mainly used in solar physics for estimating the upward energy generated by photospheric plasma motion. This study presents a pioneering 3D mapping of the magnetic energy transport within a numerically simulated solar atmosphere. By calculating the Finite Time Lyapunov Exponent of the energy velocity, defined as the ratio of the Poynting flux to the magnetic energy density, we precisely identify the sources and destinations of the magnetic energy flow throughout the solar atmosphere. This energy mapping reveals the presence of transport barriers in the lower atmosphere, restricting the amount of magnetic energy from the photosphere reaching the chromosphere and corona. Interacting kinematic and magnetic vortices create energy channels, breaking through these barriers and allowing three times more energy input from photospheric motions to reach the upper atmosphere than before the vortices formed. The vortex system also substantially alters the energy mapping, acting as a source and deposition of energy, leading to localized energy concentration. Furthermore, our results show that the energy is transported following a vortical motion: the Poynting flux vortex. In regions where these vortices coexist, they favor conditions for energy dissipation through ohmic and viscous heating, since they naturally create large gradients in the magnetic and velocity fields over small spatial scales. Hence, the vortex system promotes local plasma heating, leading to temperatures around a million Kelvins.
Deep Chandra Observations of A2495: A Possible Sloshing-regulated Feedback Cycle in a Triple-offset Galaxy Cluster
Authors: Rosignoli L. , Ubertosi F. , Gitti M. , Brighenti F. , Pasini T. , O’Sullivan E. , Gastaldello F. , Gaspari M. , Temi P.
Published: February 2024

We present the analysis of new, deep Chandra observations (130 ks) of the galaxy cluster A2495. This object is known for the presence of a triple offset between the peaks of the intracluster medium (ICM), the brightest cluster galaxy (BCG), and the warm gas glowing in Hα line. The new Chandra data confirm that the X-ray emission peak is located at a distance of ∼6.2 kpc from the BCG, and at ∼3.9 kpc from the Hα emission peak. Moreover, we identify two generations of X-ray cavities in the ICM, likely inflated by the central radio galaxy activity. Through a detailed morphological and spectral analysis, we determine that the power of the active galactic nucleus (AGN) outbursts (P
cav = 4.7 ± 1.3 × 1043 erg s−1) is enough to counterbalance the radiative losses from ICM cooling (L
cool = 5.7 ± 0.1 × 1043 erg s−1). This indicates that, despite a fragmented cooling core, A2495 still harbors an effective feedback cycle. We argue that the offsets are most likely caused by sloshing of the ICM, supported by the presence of spiral structures and a probable cold front in the gas at ∼58 kpc east of the center. Ultimately, we find that the outburst interval between the two generations of X-ray cavities is of the order of the dynamical sloshing timescale, as already hinted from the previous Chandra snapshot. We thus speculate that sloshing may be able to regulate the timescales of AGN feedback in A2495, by periodically fueling the central AGN.
Red Asymmetry of H
α
Line Profiles during the Flares on the Active RS CVn-type Star II Pegasi
Authors: Cao Dongtao , Gu Shenghong
Published: February 2024

Stellar coronal mass ejections (CMEs) have recently attracted much attention for their impacts on stellar evolution and surrounding exoplanets. RS CVn-type stars could produce large flares, and therefore may have frequent CMEs. Here we report the capture of a possible CME or chromospheric condensation on the RS CVn-type star II Pegasi (II Peg) using high-resolution spectroscopic observation. Two flares were detected during the observation, and the low limits of the flare energies are of the order of 1033 erg and 1034 erg, respectively. Using mean spectrum subtraction, the H
α
residual shows red asymmetry during the flares, and the redshifted broad emission components are probably caused by chromospheric condensation or coronal rain. Moreover, a far redshifted extra emission component with a high bulk velocity of 429 km s−1 was observed during the second flare and is probably due to a prominence eruption. The velocity greatly exceeds the star’s escape velocity, which means that this eruption can develop into a CME. The CME mass is estimated to be 0.83–1.48 × 1020 g, which is slightly larger than the value expected from solar flare-CME extrapolation. The kinetic energy of CME, derived to be 0.76–1.15 × 1035 erg, is less than the kinetic energy extrapolated from solar events. Additionally, we could not completely rule out the possibility of chromospheric condensation resulting in the far redshifted extra emission. Finally, there is a blueshifted broad component in the subtracted H
α
profile derived using synthesized spectral subtraction when no flare happened, and its behavior is associated with the H
α
activity features.
Effect of residence time on trait evolution in invasive plants: review and meta-analysis
Authors: Gruntman Michal , Segev Udi
Published: February 2024

The success of invasive species is often attributed to rapid post-introduction evolution, due to novel selection pressures at the introduced range. However, evolutionary shifts in invasion-promoting traits can also take place within the introduced range over time. Here, we first present a review of the proposed hypotheses regarding the selection pressures and trait divergence along gradients of invasion history and the studies that examined them. In addition, we present the results of a meta-analysis aimed to provide a more general overview of current knowledge on trait evolution with time since introduction. Invasion-promoting traits, including growth, competitive ability and dispersal ability, were proposed to decline in more established populations with a long invasion history due to the attenuation of selection pressures, such as enemy release or interspecific competition, while herbivore defence was suggested to increase. Our meta-analysis results reveal a general indication for the evolution of invasive plants with residence time for most of the studied traits. However, this divergence did not have a consistent direction in most traits, except for growth, which, in contrast with our prediction, increased with residence time. The lack of empirical support for the predicted change in most of the studied traits over time suggests trait evolution might be affected by other context-dependent factors such as climatic gradients along invasion routes. Similarly, the increased allocation to size in older and more established populations may be driven by increased conspecific competition pressure experienced in these populations. The general temporal effect found in our meta-analysis stresses the need to consider population age when comparing attributes of invasive plants between native and invasive ranges. Moreover, the increased size of invasive plants in older populations, suggests that the dominance of these plants might not attenuate with time since introduction, thus highlighting the need to further explore the long-term dynamics between invasive plants and their recipient native communities.

Published: February 2024

A new species of the genus Leptobrachella, L. guinanensissp. nov., is described in this study based on morphological, molecular, and bioacoustic data. The species was discovered in the Shiwandashan National Nature Reserve in Shangsi County, Guangxi, China. Phylogenetically, L. guinanensissp. nov. is closely related to L. ventripunctata. However, there are distinct morphological differences between L. guinanensissp. nov. and L. ventripunctata, as well as three other sympatric species (L. shangsiensis, L. shiwandashanensis, and L. sungi). These differences include body size (SVL 30.5–32.5 mm in males; 38.7–41.8 mm in females in the new species vs 25.5–28.0 mm in males, 31.5–35.0 mm in females in L. ventripunctata), the absence of brown spots on the ventral surface (vs chest and belly creamy white with many scattered brown spots in L. ventripunctata), 1/3 toe webbing and wide toe lateral fringes (vs no toe webbing and no lateral fringes in L. ventripunctata), and distinct dermal ridges under toes (vs absent in L. ventripunctata). Furthermore, the dominant vocal frequencies of the new species range from 7.3 to 8.3 kHz, which is unique compared to other Leptobrachella species and represents the highest dominant frequencies ever recorded. The Shiwandashan National Nature Reserve is now home to four known sympatric species of Leptobrachella.

Published: February 2024

Monobulb garlic, distinguished by its elevated allic.in content, has garnered heightened consumer interest due to its perceived health benefits. However, the challenge lies in scaling up production to meet this demand. This study investigates the potential enhancement of monobulb garlic growth by employing a novel approach that combines corona glow discharge plasma radiation technology and organic fertilizers. By employing a factorial complete randomized design with nine treatments and three repetitions, the research evaluates the impact of varying durations of plasma radiation (0, 15, and 30 minutes) and levels of organic fertilizers (0, 31.25, and 62.5 grams). Key growth parameters, including plant height, leaf count, root length, and root quantity, were measured. Results indicate that the optimal combination for growth enhancement involves 30 minutes of radiation coupled with 31.25 grams of organic fertilization. In conclusion, the integration of corona glow discharge plasma radiation technology and organic fertilization proves effective in promoting the growth of monobulb garlic plants.
Il diavolo con gli occhiali. Sciascia, inquisiti e inquisitori
Authors: Cencetti Alice
Published: February 2024

Questo saggio vuole suggerire spunti di riflessione intorno a uno dei nuclei fondanti “il sistema Sciascia”, ossia il tema della giustizia e delle sue multiformi sembianze. Attraverso due gotici politici come Il contesto e Todo modo, e attraverso la produzione saggistica e giornalistica e i più recenti studi biografici, si cerca di delineare il profilo di Sciascia come intellettuale nemico della retorica nazionale, alieno da ogni forma di velleitarismo e ingenuo ottimismo progressista. Neoilluminista che coltiva il valore del dubbio accanto alla fiducia nella ragione, propone una ricerca incessante della verità, che non può essere disgiunta dall’inveramento di una giustizia più giusta.
Sciascia uomo di cinema
Authors: Campani Ermelinda M.
Published: February 2024

Il rapporto tra Leonardo Sciascia e il cinema è sfaccettato e intrinsecamente contraddittorio. Questo breve contributo intende accennare a due percorsi. Uno è quello di Sciascia spettatore, recensore e scrittore di cinema, e l’altro riguarda l’adattamento dei romanzi sciasciani.Gli scritti sciasciani di cinema, insieme alle testimonianze dei suoi contemporanei, aiutano a dare conto dell’inizio del rapporto tra lo scrittore e la nuova arte, e di un cinema come viatico di fenomenali scoperte culturali (ad esempio, quella di Luigi Pirandello, a cui Sciascia si avvicinò innanzi tutto attraverso il cinema). Nel corso degli anni, la giovanile e frenetica cinefilia di Sciascia si era andata attenuando. Lo scrittore non praticava più le sale cinematografiche avendo preferito fare del cinema un luogo di memoria e di riflessione.Dopo questo resoconto, il saggio offre un excursus attraverso il tanto cinema italiano che si è appropriato della lettera sciasciana. Sciascia, cioè, come fonte di storie per tutta una generazione di cineasti e per una grande parte del cinema italiano engagé. Da ultimo, si fa riferimento sia agli elementi cinematografici presenti nella scrittura sciasciana, sia alla unicità del poliziesco di matrice sciasciana che rompe con i canoni del genere e, così facendo, va al cuore di una questione prettamente cinematografica, quella del rapporto tra ciò che si vede e ciò che è.

Ensuite, on aborde l’intérêt général de Sciascia pour Paris et les auteurs français de l’époque des Lumières. Après cela, il est question de l’utopie de la tolérance religieuse dans Candide de Voltaire. Pour préparer l’analyse de Candido de Sciascia, on évoque ensuite l’omertà dans l’histoire de la Sicile et la représentation de cette loi du silence (souvent liée à la mafia) dans les romans précédents de Sciascia. Dans la dernière partie de cet article, on examine en détail la rupture de l’omertà dans Candido de Sciascia, une vision utopique par rapport aux conditions sociales réelles de la Sicile de l’époque.
La storia che non cambia. La Sicilia di Leonardo Sciascia
Authors: Verri Andrea
Published: February 2024

Attraverso la lettura di saggi, articoli, interviste e testi d’occasione, scritti dagli anni ’60 agli anni ’80, si tratteggia un quadro sostanzialmente costante di quanto Sciascia dice della propria regione, della sua identità, della storia che l’ha resa com’è. Nel momento iniziale del periodo preso in esame, almeno in parte, pare esservi un certo ottimismo sulla possibilità di ottenere un cambiamento positivo. In ogni caso lo scrittore mantiene sostanzialmente invariata l’immagine di una condizione negativa e immutata attraverso i secoli, che, già a metà degli anni ’60, a fronte delle delusioni per il presente, allunga a sua volta le sue ombre anche sul momento vissuto. Nonostante le perplessità a volte dichiarate sul fatto che l’identità siciliana abbia potuto mantenersi invariata per secoli, lo scrittore lo accetta e alcune rare volte cede ad alcuni luoghi comuni.
La répartie : place et enjeux dans les Discours des misères de ce temps de Pierre de Ronsard
Authors: Ndong Sangoul
Published: February 2024

Dans sa Responce aux injures et calomnies des predicans et ministres de Geneve sur son Discours et Continuation des misères de ce temps (1563), Ronsard promet de ne rien cacher de sa vie lorsqu’il entame sa réponse à Bernard de Montméja sur quelques points le concernant. Le mensonge devient ainsi non envisageable dans la Responce. Il est repoussé avec force. Mais faut-il croire tout ce que Ronsard dit dans sa polémique contre les protestants ? Les formules d’attestation ne relèvent-elles pas dans sa Responce d’un artifice rhétorique ? Faut-il aussi voir les huguenots tels que Ronsard tente de les faire voir ? C’est autour de ces interrogations que s’articule cette étude sur la répartie dans les Discours des misères de ce temps.
Les mobilités internes en Tunisie depuis la fin des années 1990 : une dynamique géographique à différentes échelles
Authors: Ben Hamza Hajer , Guérin-Pace France
Published: February 2024

Cet article s’intéresse aux mouvements migratoires à l’intérieur de la Tunisie dans une période particulière qui encadre l’année 2011. Il mobilise deux sources distinctes de données, le recensement de 2014 et une enquête en population générale (ETST, 2016). A partir de ces deux sources de données, il cherche à dessiner une géographie des mobilités tunisiennes sur cette période récente. Au–delà des inégalités régionales anciennes entre les régions littorales et périphériques, il montre les contrastes qui s’inscrivent à différentes échelles du territoire tunisien. La particularité des mobilités internes qui ont suivi les événements de 2011, invisibles dans le recensement, apparaissent comme des mouvements le plus souvent temporaires saisis par l’enquête ETST.

The accessibility and efficacy of healthcare services rely on a fundamental element that is often underestimated: the capacity to understand and engage with health information. It's universally acknowledged that access to healthcare is a basic right for all individuals. In the Indian context, a country marked by significant socio-economic disparities and a rich mosaic of cultural and linguistic diversity, the matter of comprehending and effectively utilizing health information has emerged as a pressing and critical concern. This study investigates the paramount importance of health information comprehension in India's response to the COVID-19 pandemic.
Navigating Mental Health Crises
Authors: Komalasari Rita
Published: February 2024

This study delves into personal narratives of mental health crises and psychiatric treatment, comparing them with an extended Caplan's Crisis Theory. The objective is to unravel identifiable phases and turning points in these narratives, challenging traditional diagnostic categories and advocating for a paradigm shift in crisis intervention strategies. Through meticulous analysis, distinct phases of mental health crises emerged, showcasing the impact of interventions on recovery trajectories. Proposed alternative crisis categories highlighted the universal quest for safety and professional care, countered by social barriers. The study calls for a paradigm shift in mental health services, emphasizing psychosocial factors and community support. Through empathetic understanding and strategic interventions, mental health services can be restructured to be more responsive, fostering recovery and resilience among individuals facing mental health crises.
Equity, Fairness, and Cultural Pride
Authors: Beck Carmen Luz Maria
Published: February 2024

In this chapter, the author starts with her own story as a Latina immigrant and educator exploring firsthand her cultural experience. Then a brief introduction ensues about the current socio-political climate and the new call to equity in education by the federal government as well as changes in demographics in our schools. A historical review on education follows, critical to highlight the trends of exclusion and integration, or lack thereof, for diverse populations in the United States. After a literature review of culture and education, the researcher will identify the most important points to keep in mind when designing learning for our students so we can ensure fairness and equity as well as nurture students' identities. This trilogy of a personal testimonio, literature review, and research on best educational practices will provide some guidance in the way we can help our students thrive, become confident learners, and learn how to contribute to their communities as they form their identities.

The performance of a commercial GMR with a double-chip configuration has been investigated for detecting nanotag. Fe3O4magnetic nanoparticles (MNPs) as tags were synthesized by co-precipitation method based on green synthesis usingMoringa oleifera(MO) extract. Fe3O4showed a soft ferromagnetic material and a magnetic saturation of 55.0 emu/g. MNPs-ethanol solution are dropped onto the surface of each chip of the sensing element. As a comparison, the performance of a single-chip configuration is also investigated. Obtained bias magnetic field used as a magnetic field sensing double-chip sensor is 3.8 Oe smaller than the single-chip sensor, which is 4.3 Oe, confirmed by the shift in the value of the first derivative order. Configuration of double-chip sensor in detecting Fe3O4has a smaller LoD of 2.4 mg/mL compared to the single-chip configuration of 3.8 mg/mL. Therefore, Green-synthesized Fe3O4as biocompatible magnetic tags in combination with commercial GMR sensors using double-chip configuration is promising for magnetic-based biosensor applications in driving more responsive detection and enabling portability by using a smaller energy source.

A Comprehensive Testing Program of Flexible Pipe Armor Wire Against CO2 and H2S Towards Excellent Flexible Pipe Integrity Management System
Authors: Aziz Mohd Faisal B , Razak Siti Aishah Ali Noor , Karim Khairul Anuar , Hussien Hayati
Published: February 2024

This paper explains PETRONAS’ effort to establish partial pressure limits of CO2 and H2S and SN-curve of flexible armor wire through a comprehensive testing program. This is following an incident in 2020 where PETRONAS suffered more than RM 500mill of production losses alone excluding the cost to remove and replace with new flexible riser to resume production. By stablishing these limits, it assists the operator to plan necessary procedure to deal with elevated CO2 and H2S during operation, hence avoiding future recurrence of incidents.
Application of Autonomous Outflow Control Devices to Optimise Three Simultaneous Operations in Monobore Wells, Case Study of Offshore China
Authors: Xiong S. , Cheng J. , Ren F. , Moradi M.
Published: February 2024

In a recent intervention campaign, improved field recovery was targeted by CNOOC through redesign of completions of several wells at Offshore China. This was to maximise the production and injection capacity of each platform with limited available wells per platform. Therefore, a new completion design was suggested that could accommodate performing three operations using one single completion wellbore simultaneously. The new completion comprises a system that allows oil production from the deepest reservoir (operation 1) while the string is used to produce water from the shallowest reservoir (operation 2) and re-inject the water down to the deeper reservoirs without bringing water up to the surface (operation 3).

However, the control of fluid influx and outflux for each section of the wells was key to the success of the campaign especially since the reservoir management plan requires maintaining prescribed injection profiles. Focusing on injection operation and considering the risks associated with reservoir uncertainty and the likelihood of development of thief zones, it was recognised that the challenges could be mitigated by deploying autonomous outflow control devices (AOCDs). The device allows the flow of a certain amount of fluid toward the reservoir while autonomously closing after reaching a designed flowrate.

As mentioned above, the wells usually pass through a water-bearing zone vertically where the water would be produced and pumped down to be injected into a middle reservoir. This middle reservoir section normally comprises a few separate sub-layers. This section of the wells was then divided into several completion zones separated by swellpackers with an appropriate number of AOCD installed on the screens in each zone. An integrated workflow was followed to deliver successfully the AOCD application for these complex wellbores. The workflow comprised performance evaluation of the basecase completions and sensitivity analyses to determine the best AOCD completions for the wells.

The performance of one of the wells equipped with AOCD completion shows the devices have managed to achieve the prescribed outflow injection profile to these sub-layers supporting the nearby wells based on the reservoir management plan.

This study demonstrates the possibility of maximizing the net value of each well drilled using new technologies. The AOCD completion enabled the operator to implement an optimum reservoir drainage strategy that uses downhole control which autonomously control the flow based on well dynamic conditions.
