An Experimental Investigation on Mechanical Properties of Bacterial Concrete Using Bacillus Subtilis
Authors: Puram Anchal
Published: May 2024

Abstract: This Concrete is susceptible to micro crack formation and has pores which are highly undesirable because they provide an open pathway for the ingress of water and other deleterious substances. The use of concrete surface treatments with water proofing materials to prevent the access of aggressive substances is a common way of contributing to concrete durability. However, the most common surface treatments use organic polymers (epoxy, acrylics and polyurethanes) all of which have some degree of toxicity. Bio inspired materials can lead to a more sustainable construction industry, especially when providing new low toxic solutions. Hence, there is an urgent need to pay more attention for improving the properties of concrete with respect to strength and durability, especially in aggressive environments. One effective remedy for closure of cracks is the Bacterial Concrete (BC) which will continuously deposit calcite in concrete. This, phenomenon is called as Microbiologically Induced Calcite Precipitation (MICP). The urease enzyme enables the deposition of calcium carbonate (CaCO3) with the help of bacteria. The bacterial remediation technique surpasses other techniques as it is bio-based, eco-friendly and durable. Bacteria need to offer resistance to withstand high pH of concrete and mechanical stresses during mixing. In these present investigations bacterial sample name Bacillus Subtilis (BS) is considered in concentrations of 104 , 105 and 106 cells/ml of mixing of water. investigations are carried out on strength-related properties such as compressive strength, splitting tensile strength and flexural strength to assess the quality of concrete. The optimum dosage of cell concentration of bacteria is found to be 105 cells/ml for BS based on compressive strength results. M25 grade concrete is designed and used for embedding Bacillus subtilis bacteria.

Abstract: The purpose of the current study was to cultivate laddu by adding different amounts of flaxseed. to evaluate laddu, including its microbiological, tactile, and textural qualities, as well as its chemical and fatty acid composition and antioxidant activity. The primary objective of this research endeavor was to explore the potential enhancement of laddu, a traditional Indian sweet, through the incorporation of varied proportions of flaxseed. This exploration encompassed a multifaceted evaluation, including microbiological scrutiny, tactile discernment, textural analysis, chemical profiling, fatty acid characterization, and assessment of antioxidant potency. The procedural standardization entailed the utilization of sesame seeds, jaggery, and whole flaxseed in the formulation of Nutra Laddu. Distinct formulations denoted as T1, T2, T3, T4 were devised, featuring incremental adjustments in the proportion of whole flaxseed, ranging from 0% to 50%. Subsequent to the preparation process, the laddu specimens underwent meticulous evaluation of their organoleptic attributes, encompassing considerations such as color and visual appeal, flavor profile, textural attributes, taste perception, and overall palatability. This comprehensive assessment was facilitated through the application of a 9-point hedonic scale, enabling nuanced appraisal. Furthermore, it emerged from the analysis that Nutra Laddu fortified with flaxseed presents a notable nutritional profile, characterized by heightened levels of dietary fiber and protein. This underscores the potential of flaxseed as a valuable adjunct in laddu formulation, given its recognized nutritional and therapeutic attributes.

Magic of quantum hypergraph states
Authors: Chen Junjie , Yan Yuxuan , Zhou You
Published: May 2024

Magic, or nonstabilizerness, characterizes the deviation of a quantum state from the set of stabilizer states, playing a fundamental role in quantum state complexity and universal fault-tolerant quantum computing. However, analytical and numerical characterizations of magic are very challenging, especially for multi-qubit systems, even with a moderate qubit number. Here, we systemically and analytically investigate the magic resource of archetypal multipartite quantum states—quantum hypergraph states, which can be generated by multi-qubit controlled-phase gates encoded by hypergraphs. We first derive the magic formula in terms of the stabilizer Rényi-α entropies for general quantum hypergraph states. If the average degree of the corresponding hypergraph is constant, we show that magic cannot reach the maximal value, i.e., the number of qubits n. Then, we investigate the statistical behaviors of random hypergraph states' magic and prove a concentration result, indicating that random hypergraph states typically reach the maximum magic. This also suggests an efficient way to generate maximal magic states with random diagonal circuits. Finally, we study hypergraph states with permutation symmetry, such as 3-complete hypergraph states, where any three vertices are connected by a hyperedge. Counterintuitively, such states can only possess constant or even exponentially small magic for α≥2. Our study advances the understanding of multipartite quantum magic and could lead to applications in quantum computing and quantum many-body physics.

The study aimed to assess the ecotoxicological risk associated with the indiscriminate disposal of spent engine oil on terrestrial ecosystem using earthworm and microbial assays. Soil samples were collected from a depth of 0-20 cm and subjected to standard analytical protocols for analysis. Earthworms (assessed by mortality rate) and microorganisms (evaluated for inhibitory effects) covered a wide range of short-term lethal and sub-lethal endpoints used for risk characterization, analyzed through Probit analysis. The result of acute toxicity assay revealed that microbial absorbance rated depended on the dose and type of organism, ranking in the order: Acinetobacter > Enterobacter > Bacillus species >Pseudomonas. Aas oil concentratoin increase, mortality among earthworm was observed.  Risk Quotient (RQ) values for Zea mays, Vigna unguiculata, Glycine max and earthworm varied from low to very high risk based on estimated Predicted No Effect Concentration (PNEC) values. Microorganisms exhibited differing level of biotolerance to spent engine oil exposure as indicated by respective risk quotient values. Exposure to spent engine oil posed minimal risk to Pseudomonas sp., Bacillus sp., and Acinetobacter sp.,  with RQ values below unity (< 1). Conversely, Enterobacter sp. Showed a high risk with values above unity. Earthworms play a pivotal role in agriculture due to their numerous economic benefots. Soil microorganisms are essential for maintening soil quality by performing vital processes. The antimicrobial properties of spent engine oil on soil may distort microbial activities, potentially inhibiting their growth and leading to alterations in ecological functionality of the soil.
Contributions from en route weather amelioration to spring arrival advancement of long distance passerine migrants
Authors: Eddowes Mark
Published: May 2024

The interannual variation in arrival timing of Whitethroat in England is
strongly correlated with temperature and wind speed at locations to the
south, along the migration route through Europe, with higher
temperatures and lower wind speed, in particular at more northerly sites
in France, associated with earlier arrival. Analysis of en route weather
conditions demonstrates significant warming and wind stilling during the
migration period in recent years, suggesting a potential role for
amelioration of weather conditions in the observed advancement trend of
arrival. When linked to the meteorological trends, quantified reaction
norms derived from the interannual variations indicate that perhaps
close to half of the recently observed arrival advancement for this
species might be explained by plasticity of this sort. According to this
mechanism, less favourable weather conditions that were previously more
prevalent will have retarded progress during migration to a greater
extent prior to recent climate change-dependent amelioration of the
weather which now reduces delays to onward migration. However, the wider
literature indicates that there has been advancement of Mediterranean
passage of long-distance passerine migrants of a similar magnitude as
the advancement of Whitethroat arrival in England, suggesting a limited
role for this proposed mechanism. Earlier arrival in these European
passage areas may offset the potential for further advancement due to
warmer temperatures and lower wind speeds. It may mean that birds will
continue to encounter similar meteorological conditions as was
previously the case but, having advanced passage of the Mediterranean,
slightly earlier in the year and so providing for progress through
Europe at a broadly similar, meteorologically moderated rate.
Amelioration of en route weather conditions may still make an important
contribution to arrival advancement since, without it, earlier arrival
in Europe could result in increased delays to onward migration.

hydroxide, inner salt, triethylammonium salt ( S2), efficiently
result in physical drying of an aqueous dispersion comprising a
polyurethane binder. S2 possesses a water solubility of 40 g/L.
A high-intensity NIR-LED emitting at 820 nm with an intensity of 1 W/cm
served as light source. The cyanine converted the
light absorbed into heat by internal conversion needing less drying time
compared to conventional drying. Water content after film formation
showed less then 1%. In the second step, UV exposure with a LED
emitting at 395 nm resulted in formation of semi-interpenetrating
polymer networks by crosslinking of the multifunctional (meth)acrylate
operating as reactive diluent. TPO-L served as effective
UV-photoinitiator. Furthermore, the UV-exposure together with Norrish
Type I and Type II photoinitator systems results in a very efficient
bleaching of the green physical dried film. This contribution shows for
the first time a new photonic hybrid technique describing successful
replacement of an oven-based process by a photonic based step that
generates heat needed for drying.
Isotropic high-frequency radiation in near-fault seismic data
Authors: Ben-Zion Yehuda , Zhang Siyuan , Meng Xiaofeng
Published: May 2024

We systematically compare Fourier Amplitude Spectra of Fault Normal (FN)
and Fault Parallel (FP) seismograms at near-fault sites for 11
strike-slip earthquakes with magnitudes M≥6. For all events we find
large FN/FP ratios at low frequencies consistent with the S-wave
radiation patterns for strike-slip earthquakes near the faults. However,
the difference diminishes with increasing frequency and FN/FP is about 1
above a transition frequency. The results may reflect small-scale
isotropic source terms in the earthquake rupture zones that homogenize
the high-frequency radiation in different directions at near-fault
sites. The FN/FP ratios at low frequencies and transition frequencies
above which FN ~ FP vary among the 11 earthquakes, and
have no clear correlation with the moment magnitudes. The lack of
correlation may signify a characteristic rupture length scale (e.g.,
process zone size) controlling the isotropic radiation and/or wave
propagation and other effects that mask the source effects.

Although Mars today does not have a core dynamo, magnetizations in the
Martian crust and meteorites suggest a magnetic field was present prior
to 3.7 billion years (Ga) ago. However, the lack of ancient, oriented
Martian bedrock samples available on Earth has prevented accurate
estimates of the dynamo’s intensity, lifetime, and direction.
Constraining the nature and lifetime of the dynamo are vital to
understanding the evolution of the Martian interior and the potential
habitability of the planet. The Perseverance rover, which is exploring
Jezero crater, is providing an unprecedented opportunity to address this
gap by acquiring absolutely oriented bedrock samples with estimated ages
from ~2.3 to > 4.1 Ga. As a first step in
establishing whether these samples could contain records of Martian
paleomagnetism, it is important to determine their ferromagnetic
mineralogy, the grain sizes of the phases, and the form of any natural
remanent magnetization. Here, we synthesize data from various
Perseverance instruments to achieve those goals and discuss the
implications for future laboratory paleomagnetic analyses. Using the
rover’s instrument payload, we find that cored samples likely contain
iron oxides enriched in Cr and Ti. The relative proportions of Fe, Ti,
and Cr indicate that the phases may be titanomagnetite or Fe-Ti-Cr
spinels that are ferromagnetic at room temperature, but we cannot rule
out the presence of non-ferromagnetic ulvöspinel, ilmenite, and chromite
due to signal mixing. Importantly, the inferred abundance of iron oxides
in the samples suggests that even <1 mm-sized samples will be
easily measurable by present-day magnetometers.
Exploring the accretion of multiple microcontinents using numerical models
Authors: Erdos Zoltan , Buiter Susanne , Tetreault Joya
Published: May 2024

During closure of an ocean through subduction and continental collision,
bathymetric highs such as microcontinents can accrete, collide, or
partially or completely subduct. Such interaction of future accreted
terranes (FATs) with the overriding continent will modify the dynamics
of the subduction zone, affecting its length and frictional resistance,
and thus the force balance of the subduction system. Accreted
microcontinents and microcontinental fragments are preserved in backarcs
and collisional orogens, demonstrating that multiple terranes can
accrete during a single Wilson-cycle, in what is termed accretionary
orogenesis. In this study, we use thermo-mechanical numerical
experiments of microcontinent-continent collision events to investigate
parameters that influence whether microcontinents accrete, subduct, or
collide. Our results indicate that multiple accretionary episodes are
possible, but that a weak basal detachment layer within each FAT is
paramount for such a scenario to occur. The introduction of a
microcontinent, or FAT, in the subduction zone will affect the balance
between slab-pull, far-field forces, and the subduction interface
resistance. The strength (and rheological stratification) of the FATs
determines the evolution of the subduction interface resistance
throughout the collision event, exerting a first order control on the
resulting geodynamic scenario. Collision with a strong FAT significantly
increases the subduction interface resistance promoting terrane
subduction and localization of deformation away from the subduction
interface. In turn, collision with a weak FAT increases subduction
interface resistance only mildly, allowing for multiple accretion
events.
Remobilization of Inverted Normal Faults Drives Active Extension in the Axial Zone of the Southern Apennines Mountain Belt (Italy)

Published: May 2024

The Irpinia region is one of the most seismically active areas of Italy
due to ongoing, late-orogenic extension in the axial zone of the
Apennines mountain belt. However, the 3D architecture and the nature of
the faults that drive this extension are still uncertain, posing
challenges to seismic hazard assessment. Here, we address these
uncertainties by integrating a new catalog of high-resolution
micro-seismicity (ML<3.5) complemented by earthquake focal
mechanisms, with existing 3D seismic velocity models and geological
data. We found that micro-seismicity is primarily taking place along a
segmented, approximately 60 km long, deep-seated, Mesozoic normal fault
that was inverted during the shortening stages of the Apennine orogeny
and then extensionally reactivated during the Quaternary. These findings
suggest that multiple events of reactivation of long-lived faults can
weaken their strength, making them prone to co-seismic remobilization
under newly-imposed strain fields in active mountain belts.
Multiple-band electric field responding to the geomagnetic storm on 4 November 2021
Authors: Zheng Jie , Huang Jianping , Li Zhong , Li Jing Wen , Han Ying , lu hengxin
Published: May 2024

In this paper, based on the electric field data (EFD) of the China
Seismo-Electromagnetic Satellite (CSES), which is divided into 4
frequency bands (ULF, ELF, VLF, HF) from DC to 3.5 MHz, we study the
impact characteristics of the 4 November 2021 magnetic storm activity in
different frequency bands. It was found that the electric field
anomalies caused by magnetic storms were mainly concentrated below 18
kHz, and above 18 kHz the effects were weak and gradually diminished to
negligible. In the ULF band, excluding the influence of Schumann waves,
the electric field anomalies caused by magnetic storms are mainly below
5 Hz, with the most influential frequency point being 3.4 Hz. In the ELF
band, the more obvious anomalies appear at 300 Hz – 900 Hz and above
1.8 kHz, with the most significant anomalies in the 300 Hz – 900 Hz
band around 780 Hz. In the VLF band, electric field anomalies are
concentrated in 2.5 - 10 kHz. Magnetic storms had essentially no effect
on the HF band. Magnetic storms at low and middle latitudes have a weak
effect on the ELF and VLF bands and are more pronounced in the ULF band.
During the main phase of the magnetic storm, the absolute magnitude of
variance change in the ELF and VLF bands is greater than that in the ULF
band as a whole, but the relative magnitude of variance change in the
ULF band is 10% greater than that in the ELF and VLF bands.
High-resolution climate change projections of atmospheric rivers over the South Pacific
Authors: Goddard Felix W. , Gibson Peter B , Rampal Neelesh
Published: May 2024

Atmospheric rivers (ARs) play a critical role in moisture transport
across the Southern Hemisphere mid-latitudes and often produce extreme
rainfall events across New Zealand. Here we examine ARs in a new set of
high-resolution (12km) dynamically downscaled simulations from select
CMIP6 models. We begin with a historical evaluation of AR properties
from this model ensemble followed by future projections. We demonstrate
that by end-of-century, the maximum integrated vapour transport
associated with ARs will robustly increase by as much as 20% in some
regions of the South Pacific, and ARs contribute a larger proportion (up
to 20% more) of the annual precipitation climatology in certain regions
of New Zealand. The spatial structure and seasonality of these changes
indicate the role of a poleward shift and intensification of the
westerly jet. This is further quantified through a decomposition into
dynamic and thermodynamic components. While the thermodynamic change
dominates the increase in AR frequency, the additional positive
dynamical change is notable over the mid-latitudes and southern New
Zealand. Separating events using an AR categorisation scale shows that
higher category (longer duration, more intense) events more than double
in frequency, underscoring the increasing role that ARs will play in
extreme weather events in the future in this region.
Stratospheric Transit Time Distributions Derived from Satellite Water Vapor Measurements
Authors: Randel William J. , Podglajen Aurélien , Wu Fei
Published: May 2024

Stratospheric transit time distributions (age-of-air spectra) are
estimated using satellite water vapor (H2O) measurements from the
Microwave Limb Sounder over 2004-2021 assuming stationary transport.
Latitude-altitude dependent spectra are derived from correlations of
interannual H2O anomalies with respect to the tropical tropopause source
region, fitted with an inverse Gaussian distribution function. The
reconstructions accurately capture interannual H2O variability in the
‘tropical pipe’ and global lower stratosphere, regions of relatively
fast transport (~1-2 years) in the Brewer-Dobson
circulation. The calculations provide novel observational estimates of
the corresponding ‘short transit-time’ part of the age spectrum in these
regions, including the mode. However, the H2O results do not constrain
the longer transit-time ‘tail’ of the age spectra, and the mean age of
air and spectral widths are systematically underestimated compared to
other data. We compare observational results with parallel calculations
applied to the WACCM chemistry-climate model and the CLaMS
chemistry-transport model, and additionally evaluate the method in CLaMS
by comparing with spectra from idealized pulse tracers. Because the age
spectra accurately capture H2O interannual variations originating from
the tropical tropopause, they can be used to identify ‘other’ sources of
variability in the lower stratosphere, and we use these calculations to
quantify H2O anomalies in the Southern Hemisphere linked to the
Australian New Years fires in early 2020 and the Hunga volcanic eruption
in 2022.
Integrating Bio-Inspired Approaches with UAV-FSN Systems for Clustered Target Area Detection in Agriculture
Authors: P VANATHI
Published: May 2024

Abstract: Target area detection in agriculture plays a crucial role in optimizing crop management and resource allocation. Traditional methods often lack the precision and efficiency required for modern farming practices. Integrating bio-inspired approaches with UAV-FSN systems offers a promising solution to this challenge. By harnessing principles from nature, such as swarm intelligence and reinforcement learning, it becomes possible to optimize the deployment and coordination of UAVs within FSN for clustered target area detection in agriculture. This research explores the integration of bio-inspired approaches with UAV-FSN systems for clustered target area detection in agriculture. The increasing demand for precision agriculture necessitates efficient methods for identifying target areas affected by various factors. In this study, we introduce a novel algorithm, the QL-ABC Algorithm, which combines the Artificial Bee Colony (ABC) Algorithm with Q-Learning to optimize the deployment and movement of unmanned aerial vehicles (UAVs) within flying sensor networks (FSN) for target area detection. The performance outcomes of the proposed QL-ABC Algorithm on comparison with the existing algorithms are analysed using extensive simulation analysis with the appropriate simulation metrics: packet delivery ratio, mean end-to-end delay, and energy consumption. Results validate the usefulness of the proposed QL-ABC algorithm in accurately detecting clustered target areas in agricultural landscapes, thus contributing to advancements in precision farming practices and sustainable agriculture.

Célkitűzés: A vizsgálatban a prosztatatumorok miatt nyílt és laparoszkópos eljárással végzett radikális prostatectomiák utáni szövődmények gyakoriságát tanulmányozták intézetükben. Betegek és módszerek: A tanulmányban a 2015. 01. 01. és 2020. 01. 01. között prosztatadaganat miatt radikális prostatectomián átesett 871 beteg adatai kerültek feldolgozásra. Az 1. csoportba (n: 707) tartozó betegek esetében laparoszkópos, míg a 2. csoportba sorolt betegeknél (n:164) nyílt, retropubikus radikális prostatectomia történt. A betegek átlagos életkora 65,6±6,3 év, míg az átlagos PSA-szint az 13,1±13,0 ng/ml volt. A szövődmények osztályozása során a Clavien–Dindo-féle klasszifikációt használták. Eredmények: A korai posztoperatív szakban az 1. csoportban Clavien–Dindo-szerinti grade 1+2 szövődmény 91 esetben (12,8%) míg grade 3+4 szövődmény 19 betegben (2,6%) alakult ki. A 2. csoportban Clavien–Dindo-szerinti grade 1+2 szövődmény 91 (55,4%), míg Grade 3+4 szövődmény 9 (5,4%) fordult elő. A grade 1+2 szövődmények előfordulása szignifikánsan, (p<0,0001), míg a grade 3+4 komplikációké nem szignifikánsan (p=0,138) bizonyult magasabbnak a nyílt műtétes betegcsoportban. A késői posztoperatív szakban az 1. csoportban Clavien–Dindo-szerinti grade 1+2 szövődmény 11 alkalommal (1,5%), míg grade 3+4 szövődmény 12 betegben (1,7%) alakult ki. A 2. csoportban Clavien–Dindo-szerinti grade 1+2 szövődmény 5 esetben (3,0%), míg grade 3+4 szövődmény 7 alkalommal (4,2%) fordult elő. A késői komplikációk vonatkozásában sem a grade 1+2, sem a grade 3+4 szövődmények tekintetében nem volt szignifikáns különbség az 1. és a 2. csoport között (p=0,346 és p=0,122). Következtetések: Az eredmények alapján megállapítható, hogy a posztoperatív szövődmények lényegesen gyakrabban fordultak elő a nyílt műtéten átesett betegekben. Szignifikáns eltérést azonban csak a korai komplikációk esetében, az enyhébb (grade 1+2) formákban tapasztaltak a két csoport között.

Hangsúlyozzák – az ellátásban és a terápiás lehetőségekben – az onkoteam jelentőségét, abban az esetben is, amikor további aktív terápiára már nincs lehetőség, továbbá a működését előíró jogszabályok egyes aspektusait, azok gyakorlati jelentőségét. A csontáttétek ellátása (a malignus alapbetegség szokásos terápiáján túl) a lokális műtéti és sugárterápiás beavatkozások mellett csaknem minden esetben szisztémás terápiát is igényel. Bemutatják a zoledronsav (egyedüliként igazolt hatásosságú biszfoszfonát), a „Receptor activator of NF-kB” (RANK) rendszeren ható denoszumab, az alfa- és béta-sugárzók alkalmazását, a mindennapos betegellátásban fontos szempontokat és a mellékhatásokat. A palliatív medicina interdiszciplináris jellegét, a betegen kívül környezetének igényeihez való alkalmazkodását és az ellátás minél hamarabb történő fontosságát emelik ki.
Mass Movements, the Sacred, and Personhood in Ellul and Bataille: Parallel Sociological Analyses of Liberalism, Fascism, and Communism
Authors: Roy Christian
Published: May 2024

An instructive comparison can be drawn between Jacques Ellul’s 1936 Esprit article portraying “Fascism as Liberalism’s Child” and Georges Bataille’s 1938 lecture on “The Sacred Sociology of Today’s World”. Both rely on Durkheim’s sociology in assuming modernity’s amorphousness, leaving passive masses of atomized individuals susceptible to mobilization into totalized entities by charismatic leadership. Bataille welcomes the postwar intensification of social aggregates but criticizes their militant, militaristic regimentation as not violent and sacred enough, whereas for Ellul, the resurgent social sacred (whether orgiastic or dictatorial), as the active mass, is the enemy of the free person as the sole meaningful whole.

Drugs has since become a major source of livelihood for Nigerians. It also accounts for over 85% of the total food consumed within her borders. The sector has maintained improved productivity and profitability via a concerted effort to address critical issues such as an unorganized regulatory system, lack of food safety data, no standards in agricultural produce, non-adaptation to precision farming, and non-harmony via inventory trace supports. This study proposes blockchain-based tracer-support system in a continued effort to ensure food quality, consumer safety, and trading of food assets. It uses the radio-frequency identification sensors to register and trace drugs manufacture cum administration process and provide a databank to trace the drug records via the shipment to its distribution centers. To ascertain, if the drug is genuine or fake, the user scans the QRcode via the mobile application API, which then generates feedback. Results achieves the following: (a) presents a framework and roadmap for adoption by the National Agency for Food and Drug Administration and Control (NAFDAC) to ensure pharmaceutical blockchain, (b) show ensemble is scalable for up-to 7500users to yield a performance of 1138-transactions per seconds with response time of 88secs for page retrieval and 128secs for queries respectively, and (c) yields slightly longer time for increased number of users via its world-state as stored in the permissionless blockchain hyper-fabric ledger. Thus, the framework can directly query and retrieve data without it traversing the whole ledger. This, in turn, improves the efficiency and effectiveness of the traceability system.

Authors: Singh Sukhdev , Malik Toseef
Published: May 2024

In this manuscript, the new sequence space Z? for Z ? {c, c0, ??} and ? = Cm? have been introduced using the Ces?ro matrix and backward difference operator. Some of the topological properties of these spaces have been studied and the existence of the Schauder basis for new spaces have been verified. Also, the ?, ? and ?-duals have been computed along with the characterization of the matrix transformation between new spaces.
On the set of all generalized Drazin invertible elements in a ring
Authors: Peng Fei , Zhang Xiaoxiang
Published: May 2024

Berkani and Sarihr [Studia Math. (2001) 148: 251-257] showed that the set of
all Drazin invertible elements in an algebra over a filed is a regularity in
the sense of Kordula and M?ller [Studia Math. (1996) 119: 109-128]. In
this paper, the above result is extended to the case of a ring.
Counterexamples are provided to show that the set of all generalized Drazin
invertible elements in a ring need not be a regularity in general. We
determine when the set of all generalized Drazin invertible matrices in the
2 ? 2 full matrix ring over a commutative local ring is a regularity. We
also give a sufficient condition for the set of all generalized Drazin
invertible elements in a ring to be a regularity.
On B-statistical uniform nonintegrability of a sequence of random variables
Authors: Chen Mengru , Li Guangying , Wang Zhongzhi , Zhang Yongjin
Published: May 2024

In this paper, we introduce a notion of B-statistical uniform
nonintegrability with respect to A (B-UNI(c) w.r.t. A, in short), which is
weaker than UNI(c) w.r.t. A (see [3]). We establish the de La Vall?e
Poussin criterion for B-UNI(c) w.r.t. A, which extends Theorem 2.1 of
Chandra et al. (2021) [3]. Moreover, we also give a necessary condition for
the sequence of random variables {Xk, k ? N} to be B-UNI(c) w.r.t. A.
Large deviations for stochastic pantograph integrodifferential equation
Authors: Ranjani Siva , Suvinthra M. , Balachandran K.
Published: May 2024

The pantograph equation, a specific type of delay differential equation is
examined in this study in its stochastic form. Our main intention is to
establish the Wentzell-Freidlin type large deviation estimates for
stochastic pantograph integrodifferential equation. The existence and
uniqueness of solution is established by using the method of successive
approximations. We then take up the weak convergence approach to obtain the
main result. The established results are illustrated with examples.

Published: May 2024

Objective: To identify and characterize groups of pregnant women with type 2 diabetes with distinct hemoglobin A1c (HbA1c) trajectories across gestation and to examine the association with adverse obstetric and perinatal outcomes.

Research Design and Methods: A retrospective Danish national cohort study including all singleton pregnancies in women with type 2 diabetes, giving birth to a liveborn infant, between 2004 and 2019. HbA1c trajectories were identified using latent class linear mixed model analysis. Associations with adverse outcomes were examined with logistic regression models.

Results: In total, 1129 pregnancies were included. Three HbA1c trajectory groups were identified and named according to the glycemic control in early pregnancy (good 59%, moderate 32%, poor 9%). According to the model, all groups attained an estimated HbA1c < 6.5 % (48 mmol/mol) during pregnancy, with no differences between groups in the 3rd trimester. Women with poor glycemic control in early pregnancy had lower odds of having an infant with large-for-gestational-age (LGA) birthweight (adjusted odds ratio (aOR) 0.57, 95% CI 0.40–0.83), and higher odds of having an infant with small-for-gestational-age (SGA) birthweight (aOR 2.49, 95% CI 2.00–3.10) and congenital malformation (CM) (aOR 4.60 95% CI 3.39–6.26) compared to women with good glycemic control. There was no evidence of a difference in odds of preeclampsia, preterm birth and caesarean section between groups.

Conclusions: Women with poor glycemic control in early pregnancy have lower odds of having an infant with LGA birthweight, but higher odds of having an infant with SGA birthweight and CM.
Proximal row carpectomy versus four-corner arthrodesis: a retrospective comparative study
Authors: Chan Richard , Goursat Justine , Payen Mathilde , Lalevée Matthieu , Guelmi Kamel
Published: May 2024

Background: Four-corner arthrodesis with scaphoid excision (FCA) and proximal row carpal resection (PRC) are frequently performed in wrists with post-traumatic Scaphoid Non- Union Advanced Collapse (SNAC)/Scapho-Lunate Advanced Collapse (SLAC) osteoarthritis. The aim of this study was to compare the clinical outcomes of these two procedures.
Methods: This single-center, retrospective cohort study included all patients who had PRC or FCA between January 1st, 2009 and January 1st, 2019 and who were followed up. Follow-up included: mobility (radial deviation, ulnar deviation, flexion, extension), strength (grip test, pinch test), function (QuickDash, patient-rated wrist evaluation [PRWE]), subjective mobility, and global satisfaction scores.
Results: Among 25 patients included, 11 had PRC and 14 had FCA with a mean follow-up of 69.5 months [12–132]. Radial deviation was 18° versus 14° (p = 0.7), ulnar deviation was 21° versus 22° (p = 0.15), flexion was 39° versus 30° (p = 0.32), extension was 32.5° versus 29.5° (p = 0.09), grip test compared to the controlateral side was 72% versus 62% (p = 0.53), Quick Dash score was 12.5 versus 17.6 (p = 0.84), PRWE was 18.7 versus 17.6 (p = 0.38), subjective mobility was 7.8 versus 7.5 (p = 0.23), and satisfaction score was 8.7 versus 9 (p = 0.76), respectively, in the FCA group and the PRC group. Re-operation rates were 14% patients in the FCA group and 0% in the PRC group.
Conclusion: This study found no significant difference between FCA and PRC on strength, mobility, and function in patients with post-traumatic SLAC or SNAC stage II wrist arthritis. Both FCA and PRC seem to be reliable surgical techniques with good outcomes with more revision in the FCA group.
Prediction of long-term functional outcome following different rehabilitation pathways after stroke unit discharge
Authors: Nylén Malin C. , Abzhandadze Tamar , Persson Hanna C. , Sunnerhagen Katharina S.
Published: May 2024

Objective: To investigate whether referral for different types of rehabilitation on discharge from Swedish stroke units can predict functional outcomes at 1 and 5 years after a stroke.
Design: A longitudinal and registry-based study.
Subjects/patients: A total of 5,118 participants with index stroke in 2011 were followed-up at 1 and 5 years after the stroke.
Methods: Ordinal logistic regression models were developed to predict the category of functional outcome: independent, dependent, or dead. The primary predictors were planned rehabilitation in a home setting, inpatient rehabilitation, and outpatient rehabilitation, with no planned rehabilitation as the reference category.
Results: Planned outpatient rehabilitation predicted independence (compared with death) at 1 year. Planned rehabilitation in the home setting predicted independence (compared with death) at 1 and 5 years. Compared with other planned pathways, participants planned for inpatient rehabilitation had more severe conditions, and planned inpatient rehabilitation did not predict independence.
Conclusion: Planning for outpatient or home-based rehabilitation appeared to lead more effectively to participants achieving independence over the course of 1–5 years. This may have been due to the less severe nature of these participants’ conditions, compared with those requiring inpatient rehabilitation.
