Published: May 2024

Swelling in the thigh is one of the commonly presenting condition in surgical OPD which draws curiosity among surgeons about the exact pathology and their management. These long standing swellings are mostly soft tissue tumors which are usually painless but draws attention due to their increasing size and cosmetic disfigurement. We are presenting six unusual cases of thigh swellings which are pathologically rare including Giant Baker’s cyst, Hydatid cyst and Schwannoma of thigh. One patient with secondary metastatic inguinal lymph nodes from malignant melanoma was referred to cancer institute for further management. All other patients were evaluated and surgically managed by excision and biopsy. There were no post-operative complications during 3 months follow-up period.

Entrepreneurial Creative Thinking and Venture Performance: Reviewing the Influence of Psychomotor Education on the Profitability of Small and Medium Scale Firms in Port Harcourt Metropolis
Authors: Cletus Okey Amah
Published: May 2024

The significance of small and medium enterprises to an economic development of a country cannot be overemphasized. The growth of a business depends on the development of abilities needed to execute a smooth running of day business activities. Research has established the fact that fast economic growth of regions lies on the extent of trade activities in the area. Given this established importance of enterprise, this present study aims at empirically developing the relationship between entrepreneurial creative thinking and venture performance with specific reference to small and medium scale firms in Port Harcourt metropolis. Descriptive survey design was adopted and primary data were used. The data collected were analyzed using mean, aggregate mean, and Spearman rank correlation with the aid of statistical package for social sciences, version 25. Findings shows that there is a significant and positive relationship between psychomotor education (our proxy for creative thinking) and profitability, as indicated by p-value of at 0.05 level of significance. We conclude that entrepreneurial creative thinking is an ingredient that managers of small and medium enterprises deploy to achieve maximum profit. Based on the empirical findings and conclusion, we recommend that there should be a need for policymakers to consider developing small and medium enterprises, not only through the provision of social amenities but also development of public agenda for the acknowledgement of creative thinking, skill development, and prioritization of skills improvement for both expert and non-expert business owners.

Published: May 2024

An important use of computer technology in recent years has been the automatic helmet recognition of motorcy clists in real-time surveillance film. Deep learning methods are becoming more and more popular as a result, especially for object detection and classification. Nevertheless, a number ofissues, including limited resolution, inadequate lighting, adverse weather, and occlusion, restrict the accuracy of current models in identifying motorcycle helmets. A unique method that makes use of the Faster R-CNN model has been put out to addressthese issues. Using the input image as the starting point, this method first trains the Region Proposal Network (RPN), and then it uses the RPN weights to train the Faster RCNN model. The goal of this method is to increase helmet detection accuracy in live surveillance footage. This method’s experimental results have demonstrated encouraging results, with a 95% accuracy rate in identifying motorcycle helmets in live surveillance footage.This illustrates the promise of deep learning approaches in the field of automatic helmet detection for motorcyclists in real-time surveillance film, as well as the efficacy of the suggested strategy in overcoming the issues encountered by current models.

We present the first results from the Revealing Low-Luminosity Active Galactic Nuclei (ReveaLLAGN) survey, a JWST survey of seven nearby LLAGNs. We focus on two observations with the Mid-Infrared Instrument (MIRI)’s Medium-Resolution Spectrometer of the nuclei of NGC 1052 and Sombrero (NGC 4594/M104). We also compare these data to public JWST data of higher-luminosity AGNs, NGC 7319 and NGC 7469. JWST clearly separates the AGN spectrum from the galaxy light even in Sombrero, the faintest target in our survey; the AGN components have very red spectra. We find that the emission-line widths in both NGC 1052 and Sombrero increase with increasing ionization potential, with FWHM > 1000 km s−1 for lines with ionization potential ≳ 50 eV. These lines are also significantly blueshifted in both LLAGNs. The high-ionization-potential lines in NGC 7319 show neither broad widths nor significant blueshifts. Many of the lower-ionization-potential emission lines in Sombrero show significant blue wings extending >1000 km s−1. These features and the emission-line maps in both galaxies are consistent with outflows along the jet direction. Sombrero has the lowest-luminosity high-ionization-potential lines ([Ne v] and [O iv]) ever measured in the mid-infrared, but the relative strengths of these lines are consistent with higher-luminosity AGNs. On the other hand, the [Ne v] emission is much weaker relative to the [Ne iii] and [Ne ii] lines of higher-luminosity AGNs. These initial results show the great promise that JWST holds for identifying and studying the physical nature of LLAGNs.

Published: May 2024

We perform a comprehensive CO study toward the Monoceros OB1 (Mon OB1) region based on the Milky Way Imaging Scroll Painting survey at an angular resolution of about 50″. The high-sensitivity data, together with the high dynamic range, show that molecular gas in the 8° × 4° region displays complicated hierarchical structures and various morphology (e.g., filamentary, cavity-like, shell-like, and other irregular structures). Based on Gaussian decomposition and clustering for 13CO data, a total of 263 13CO structures are identified in the whole region, and 88% of raw data flux is recovered. The dense gas with relatively high column density from the integrated CO emission is mainly concentrated in the region where multiple 13CO structures are overlapped. Combining the results of 32 large 13CO structures with distances from Gaia DR3, we estimate an average distance of

Our results show that the dense gas environment is closely linked to the nearby star-forming regions. On the other hand, star-forming activities have a great influence on the physical properties of the surrounding molecular gas (larger velocity dispersion, higher temperatures, more complex velocity structures, etc.). We also discuss the distribution/kinematics of molecular gas associated with nearby star-forming activities.
On the Origin of the X-Ray Emission in Heavily Obscured Compact Radio Sources

Published: May 2024

X-ray continuum emission of active galactic nuclei (AGNs) may be reflected by circumnuclear dusty tori, producing prominent fluorescence iron lines at X-ray frequencies. Here, we discuss the broadband emission of three radio-loud AGNs belonging to the class of compact symmetric objects (CSOs), with detected narrow Fe Kα lines. CSOs have newly born radio jets, forming compact radio lobes with projected linear sizes of the order of a few to hundreds of parsecs. We model the radio-to-γ-ray spectra of compact lobes in J1407+2827, J1511+0518, and J2022+6137, which are among the nearest and the youngest CSOs known to date, and are characterized by an intrinsic X-ray absorbing column density of N
H > 1023 cm−2. In addition to the archival data, we analyze the newly acquired Chandra X-ray Observatory and Submillimeter Array (SMA) observations, and also refine the γ-ray upper limits from Fermi Large Area Telescope monitoring. The new Chandra data exclude the presence of the extended X-ray emission components on scales larger than 1.″5. The SMA data unveil a correlation between the spectral index of the electron distribution in the lobes and N
H, which can explain the γ-ray quietness of heavily obscured CSOs. Based on our modeling, we argue that the inverse-Compton emission of compact radio lobes may account for the intrinsic X-ray continuum in all these sources. Furthermore, we propose that the observed iron lines may be produced by a reflection of the lobes’ continuum from the surrounding cold dust.

Multipeaked supernovae with precursors, dramatic light-curve rebrightenings, and spectral transformation are rare, but are being discovered in increasing numbers by modern night-sky transient surveys like the Zwicky Transient Facility. Here, we present the observations and analysis of SN 2023aew, which showed a dramatic increase in brightness following an initial luminous (−17.4 mag) and long (∼100 days) unusual first peak (possibly precursor). SN 2023aew was classified as a Type IIb supernova during the first peak but changed its type to resemble a stripped-envelope supernova (SESN) after the marked rebrightening. We present comparisons of SN 2023aew’s spectral evolution with SESN subtypes and argue that it is similar to SNe Ibc during its main peak. P-Cygni Balmer lines are present during the first peak, but vanish during the second peak’s photospheric phase, before Hα resurfaces again during the nebular phase. The nebular lines ([O i], [Ca ii], Mg i], Hα) exhibit a double-peaked structure that hints toward a clumpy or nonspherical ejecta. We analyze the second peak in the light curve of SN 2023aew and find it to be broader than that of normal SESNe as well as requiring a very high 56Ni mass to power the peak luminosity. We discuss the possible origins of SN 2023aew including an eruption scenario where a part of the envelope is ejected during the first peak and also powers the second peak of the light curve through interaction of the SN with the circumstellar medium.

n
= 0.55 μ Jy beam−1, reaching the confusion limit. Using a spectrophotometric technique combining coarse optical spectra with broadband photometry, we obtain redshifts with σ

z
≲ 0.01(1 + z), as determined from repeat observations. The resulting radio luminosity functions between 0.2 < z < 1.3 from our sample of 3839 individual galaxies are in remarkable agreement with those inferred from previous modeling of radio source counts, confirming a ≳50% excess in radio-based star formation rate density (SFRD) (z) measurements at 0.2 < z < 1.3 compared to those from the UV–IR. Several sources of systematic error are discussed—totalling ∼0.13 dex when added in quadrature. Even in the event that all systematic errors work to decrease the radio-based SFRD values, they are incapable of reconciling differences between the radio-based measurements with those from the UV–IR at 0.5 < z < 1.3. We conclude that significant work remains to have confidence in a full accounting of the star formation budget of the Universe.
Thermal Oxidation Reaction between NH3 and O3: Low-temperature Formation of an

-bearing Salt
Authors: Tribbett Patrick D. , Loeffler Mark J.
Published: May 2024

NH3 has long been predicted to be an important component of outer solar system bodies, yet detection of this compound suggests a low abundance or absence on many objects where it would be expected. Here, we demonstrate that a thermally driven oxidation reaction between ammonia (NH3) and ozone (O3) in a H2O + NH3 + O3 mixture may contribute to the low abundance of NH3 on some of these objects, as this reaction efficiently occurs at temperatures as low as 70 K. We determined the overall activation energy for this reaction to be 17 ± 2 kJ mol−1, which is consistent with other chemical systems that react at cryogenic temperatures. The loss of these two compounds coincides with the formation of

Warming our H2O + NH3 + O3 mixtures through sublimation, we find a number of higher-temperature phases, such as ammonia hemihydrate, nitric acid, and ammonium nitrate (NH4NO3). The most stable of these is NH4NO3, which remains on the substrate until temperatures near 270 K. The salt product within this sample contains near-infrared spectral features between 2.0 and 2.22 μm, which is a spectral region of interest for several outer solar system objects, including the Uranian satellites Miranda, Ariel and Umbriel, and Pluto's satellite Charon.

The phase composition, density, microhardness and fracture toughness of (ZrO2)1-x(R2O3)х crystals (where R = Y, Sm and Gd) for x = 0.02–0.04 have been compared. The crystals have been grown using directional melt crystallization in a cold crucible. The phase composition of the crystals has been studied using X-ray diffraction and Raman spectroscopy. The microhardness and fracture toughness of the crystals have been evaluated by means of indentation. At stabilizing oxide concentrations of ≥ 2.8 mol.% for Y2O3 and Gd2O3 and ≥ 3.7 mol.% for Sm2O3 the crystals have densities close to the theoretical ones and contain two tetragonal phases. At lower stabilizing oxide concentrations the crystals contain the monoclinic phase. The fracture toughness of the tetragonal crystals increases with the ionic radius of the stabilizer. The highest fracture toughness values achieved when stabilized by a specific oxide are 11.0, 13.0 and 14.3 MPa·m1/2 for the 2.8YSZ, 2.8GdSZ and 3.7SmSZ crystals, respectively. The fracture toughness proves to depend on the crystallographic orientation of the crystals. The results of this work can be used in the design and fabrication of various structural components and devices.

Sharing data, caring for collections. Open data on collection agents affiliated with the Museum für Naturkunde Berlin
Authors: von Mering Sabine , Stolze Erik , Kaiser Katja , Petersen Mareike
Published: May 2024

Linked open data on collection agents contribute to increased discoverability, accessibility and transparency of natural history collections. Despite major efforts to digitise and open up museum and university object collections, related information is often stored in internal resources. This paper describes a project conducted at the Museum für Naturkunde Berlin (MfN) contributing to its collection disclosure and development initiatives. Information on historical collectors and other collection agents was transferred from the internal MfN collector wiki to Wikidata. For a total of 600 collection agents, existing Wikidata items were enriched or new items created.

Special emphasis was put on linking these people to the Museum, to document their affiliation with the MfN, its collection and its archive. Within the project, an open participatory approach was taken. Several Wikidata edit-a-thons were organised to test this collaborative and innovative format for possible future application by the Museum. By opening up institutional silos and openly sharing data on agents connected to museum holdings, these data become more widely accessible and reusable, for example, as a resource for transdisciplinary provenance research.
Large carrion and burying beetles evolved from Staphylinidae (Coleoptera, Staphylinidae, Silphinae): a review of the evidence
Authors: Sikes Derek S. , Thayer Margaret K. , Newton Alfred F.
Published: May 2024

Large carrion beetles (Silphidae) are the focus of ongoing behavioral ecology, forensic, ecological, conservation, evolutionary, systematic, and other research, and were recently reclassified as a subfamily of Staphylinidae. Twenty-three analyses in 21 publications spanning the years 1927–2023 that are relevant to the question of the evolutionary origin and taxonomic classification of Silphidae are reviewed. Most of these analyses (20) found Silphidae nested inside Staphylinidae (an average of 4.38 branches deep), two found Silphidae in an ambiguous position, and one found Silphidae outside Staphylinidae, as sister to Hydrophilidae. There is strong evidence supporting the hypothesis that large carrion beetles evolved from within Staphylinidae and good justification for their classification as the subfamily Silphinae of the megadiverse, and apparently now monophyletic, Staphylinidae. Considerable uncertainty remains regarding the interrelationships and monophyly of many staphylinid subfamilies. Nonetheless, the subfamily Tachyporinae was found to be the sister of Silphinae in more analyses (7) than any other subfamily.

This research focuses on the fascinating exploration of the $ (2+1) $-dimensional complex modified Korteweg-de Vries (CmKdV) system, exhibiting its complex dynamics and solitary wave solutions. This system is a versatile mathematical model that finds applications in various branches of physics, including fluid dynamics, plasma physics, optics, and nonlinear dynamics. Two newly developed methodologies, namely the auxiliary equation (AE) method and the Hirota bilinear (HB) method, are implemented for the construction of novel solitons in various formats. Numerous novel soliton solutions are synthesised in distinct formats, such as dark, bright, singular, periodic, combo, $ W $-shape, mixed trigonometric, exponential, hyperbolic, and rational, based on the proposed methods. Furthermore, we also find some lump solutions, including the periodic cross rational wave, the homoclinic breather (HB) wave solution, the periodic wave solution, the $ M $-shaped rational wave solution, the $ M $-shaped interaction with one kink wave, and the multiwave solution, which are not documented in the literature. In addition, we employ the Galilean transformation to derive the dynamic framework for the presented equation. Our inquiry includes a wide range of topics, including bifurcations, chaotic flows, and other intriguing dynamic properties. Also, for the physical demonstration of the acquired solutions, 3D, 2D, and contour plots are provided. The resulting structure of the acquired results can enrich the nonlinear dynamical behaviors of the given system and may be useful in many domains, such as mathematical physics and fluid dynamics, as well as demonstrate that the approaches used are effective and worthy of validation.
Optimization study of tourism total revenue prediction model based on the Grey Markov chain: a case study of Macau
Authors: Chen Xiaolong , Zhang Hongfeng , Wong Cora Un In
Published: May 2024

The GM (1, 1) model, grounded in gray system theory, utilizes first-order cumulative data for forecasting. While offering simplicity and efficiency, its applicability is confined to such data. In light of the constraints inherent in the conventional gray GM (1, 1) prediction model when confronted with stochastic data fluctuations, the residual correction methodology was deployed to enhance the predictive efficacy of the GM (1, 1) model. Subsequently, an augmented model underwent refinement through the application of the Markov chain, giving rise to a sophisticated and optimized gray Markov chain prediction model. The efficacy of this novel model was substantiated through a case study involving the prediction of Macao's aggregate tourism revenue. A comparative analysis was conducted between the outcomes generated by the traditional gray prediction model, those of the refined prediction model, and the empirical data pertaining to tourism. This scrutiny validated the proficiency and precision of the optimized prediction model. The process of model optimization manifested a discernible enhancement in both predictive accuracy and stability, thereby broadening the prospective applications of gray prediction models. This endeavor aspired to furnish a scientifically grounded point of reference for the advancement of tourism within the Guangdong-Hong Kong-Macao Greater Bay Area and, indeed, throughout China. Moreover, it introduced a fresh methodology that held promise as a decision-making support mechanism for the developmental trajectory of Macao's tourism industry.
An Intelligent Framework for English Teaching through Deep Learning and Reinforcement Learning with Interactive Mobile Technology
Authors: Hu Jingan , Jin Gaimin
Published: May 2024

As globalization deepens, the significance of English teaching in the educational landscape has become more prominent. Traditional teaching methods are increasingly inadequate for providing personalized and efficient learning experiences. This gap is being addressed by the rapid advancements in artificial intelligence, especially through deep and reinforcement learning. These technologies provide a framework for intelligent English teaching systems by mimicking human learning processes to customize personalized learning experiences, optimize learning paths, and enhance efficiency. However, challenges remain in fine-tuning teaching strategies to meet the varying needs of individual learners and dynamically adapting to their evolving interests in the short term. This study introduces a novel framework for an intelligent English teaching system that leverages the potential of interactive mobile technology alongside a deep Q-network (DQN) algorithm to dynamically adjust English teaching strategies. This approach enables real-time personalization of teaching strategies to create optimal learning paths for individual learners. Moreover, it incorporates a model based on neural collaborative filtering to capture and adapt to learners’ short-term dynamic interests, thereby recommending relevant learning content in real-time. This framework enhances learning efficiency and personalizes content delivery, demonstrating considerable theoretical and practical value for the future of educational technology.
Horatio’s ‘mote’: mining a metaphor in Q2 Hamlet
Authors: Walsh Brian
Published: May 2024

Horatio compares the Ghost to a ‘mote’ that ‘trouble[s] the mind’s eye’ in the first scene of Hamlet, in a speech unique to the second quarto (1604). In this exercise in micro-analysis of a single line from Hamlet, I assess how this pithy metaphor helps create the texture of Q2’s version of the opening scene. Un-editing — or, more properly here, un-conflating — can help us realize something valuable about Q2 Hamlet, namely, that its opening scene does more than the opening scenes in Q1 or F to emphasize self-reflection and interiority as major themes. Further, Horatio’s pregnant comparison makes the figure of Old Hamlet morally ambiguous from the start by associating his appearance with feelings of guilt.
‘Discretion fought with nature’ (1.1.5): eulogy and jointure in Hamlet
Authors: Brailowsky Yan
Published: May 2024

The article studies the formal aspects of Claudius’ inaugural speeches in Hamlet, which mimics sermons on the inevitability of death and the holy nature of patrilinear bonds linking the dead and the living. It compares this with the suggestion that his ‘state [is] disjoint and out of frame’ (1.2.20), which recalls early modern discussions on jointure, a legal provision allowing wives to take possession of their late husbands’ lands and tenements, thereby (momentarily) dispossessing the natural heirs. Claudius’ speeches contrast the topos of the ‘natural’ cycle of life and death, and the ‘discretion’ afforded Gertrude by law to symbolically dispossess her own son in favour of a new husband and king. As Claudius makes short shrift of his eulogy for his ‘dear brother’, he paves the way for his own unceremonious death in act 5, when Hamlet chastises the infamous nature of the king’s ‘union’ or ‘jointure’ with Gertrude. Contrariwise, Hamlet succeeds in being remembered following the rules of epideictic rhetoric.
‘Hyperion’s curls, the front of Jove himself’ (3.4.56): mythological portraits in Hamlet’s closet scene
Authors: Lafont Agnès
Published: May 2024

The article shows how Renaissance humanism — the rediscovery of classical learning — is dramatised in Hamlet to pit an idealised past against a corrupted present. It focuses on the ‘closet scene’ (3.4), that, for the benefit of Gertrude’s eyes — and the audience’s —, represents Hamlet’s father, a solar king, against Hamlet’s ‘father’s brother’, a satyr, in a vivid stage image that echoes Hamlet’s line in a previous soliloquy: ‘So excellent a king, that was to this / Hyperion a satyr’ (1.2.139-40). Such contrasting mythological portraits question Gertrude’s refusal to grieve her spouse until then, even suggesting a matricidal impulse in Hamlet.
Du délire d’Ophélie (IV.v) au récit de Gertrude (IV.vii) : théâtralisation de la fragmentation, esthétique de la recomposition

« La folie, c’est le déjà-là de la mort » : tout se passe comme si la célèbre formule de Michel Foucault trouvait son illustration parfaite dans le Hamlet de Shakespeare. En mettant en regard les propos décousus d’Ophélie (IV.v) et le récit de sa noyade par Gertrude (IV.vii), deux moments indissociables au point de former un véritable diptyque, on examinera la façon dont la folie se donne à voir et à entendre sur la scène élisabéthaine, convoquant à la fois confusion, fragmentation et subversion, puis on s’interrogera sur l’esthétique de la recomposition qui informe le récit de Gertrude et fait d’Ophélie ce que Gaston Bachelard a appelé « une image fondamentale de la rêverie des eaux » qui n’a cessé d’inspirer peintres et poètes.

Published: May 2024

Recently, the existing unmanned systems of combine harvesters mostly adopts satellite navigation scheme, lacking real-time observation of harvesting adjustment. To improve the operational efficiency of combine harvester assisted navigation operation, this paper designs a combine harvester navigation control system based on vision simultaneous localization and mapping (SLAM)-inertial guidance fusion. The system acquires field image information and extracts the crop boundary line as the navigation datum by binocular camera. First, the system acquires field image information through binocular camera and extracts the crop boundary line as the navigation datum. Second, fusing camera and inertial guidance information to obtain the real-time relative position of a combine harvester. Third, constrained optimization of image and inertial guidance information is achieved through a sliding window optimization method based on tightly coupled nonlinear optimization. Finally, obtain the position of the combine harvester relative to the navigation datum line, and output a signal to the steering mechanism to realize the combine harvester in the field intelligent positioning navigation control. The system consists of binocular camera, inertial measurement unit, motorized steering wheel, monitor display, angle sensor and microcontroller. During field testing, the system underwent repetitive harvesting trials over a distance of 25 m.. The testing machine performs field operations at a speed of 0.9-1.5 m/s, with an average lateral deviation range of 2.21-8.62 cm, a standard deviation range of 0.13-4.21 cm and an average cutting rate range of 92.2%-96.0%, achieving the expected harvesting effect.

Published: May 2024

Background and Aims:

No studies have compared the effects of ketamine and dexmedetomidine on bowel recovery. We evaluated the effects of intraoperative low-dose ketamine or dexmedetomidine infusion on postoperative bowel recovery in patients undergoing gastrointestinal (GI) malignancy surgeries.

Material and Methods:

This placebo-controlled, randomized study was carried out in 84 American Society of Anesthesiologists II patients, aged 18–70 years, of either gender, undergoing elective open GI malignancy surgeries. Patients received intraoperative infusion of ketamine @ 0.1 mg kg-1 h-1 (KET), dexmedetomidine @ 0.25 μg kg-1 h-1 (DEX), or normal saline (placebo). Primary outcome was the time to first flatus and/or stool. Secondary outcomes included time to extubation, total analgesic requirement, postoperative pain scores, time to feeds, duration of intensive care unit (ICU) and hospital stay, and the incidence of adverse events. Continuous data were analyzed by the one-way analysis of variance (ANOVA) or the Kruskal–Wallis test. Categorical data were analyzed by the Chi-square test or the Fisher’s exact test.

Results:

Median time to passage of flatus and/or stool was 3 [interquartile range (IQR) 2–3] days in the KET group, 2 [IQR 2–3] days in the DEX group, and 2 [IQR 2–3] days in the placebo group (P = 0.53 for placebo vs. KET, 0.81 for placebo vs. DEX, and 0.99 for KET vs. DEX). Pain scores and analgesic consumption were significantly less in the intervention groups versus placebo (P < 0.001). No difference was seen in other secondary outcomes.

Conclusion:

Low-dose ketamine or dexmedetomidine did not result in early bowel recovery despite lower pain scores and opioid consumption in patients undergoing open GI malignancy surgeries.
Pathological set with loss of regularity for nonlinear Schrödinger equations
Authors: Carles Rémi , Gassot Louise
Published: May 2024

We consider the mass-supercritical, defocusing, nonlinear Schrödinger equation. We prove loss of regularity in arbitrarily short times for regularized initial data belonging to a dense set of any fixed Sobolev space for which the nonlinearity is supercritical. The proof relies on the construction of initial data as a superposition of disjoint bubbles at different scales. We get an approximate solution with a time of existence bounded from below, provided by the compressible Euler equation, which enjoys zero speed of propagation. Introducing suitable renormalized modulated energy functionals, we prove spatially localized estimates which make it possible to obtain the loss of regularity.
Topological finiteness properties of monoids, II: Special monoids, one-relator monoids, amalgamated free products, and HNN extensions
Authors: Gray Robert D. , Steinberg Benjamin
Published: May 2024

We show how topological methods developed in a previous article can be applied to prove new results about topological and homological finiteness properties of monoids. A monoid presentation is called special if the right-hand side of each relation is equal to

1

. We prove results which relate the finiteness properties of a monoid defined by a special presentation with those of its group of units. Specifically we show that the monoid inherits the finiteness properties

\mathrm{F}_{n}

and

\mathrm{FP}_{n}

from its group of units. We also obtain results which relate the geometric and cohomological dimensions of such a monoid to those of its group of units. We apply these results to prove a Lyndon’s Identity Theorem for one-relator monoids of the form

\langle A \mid r=1 \rangle

. In particular, we show that all such monoids are of type

\mathrm{F}_{\infty}

(and

\mathrm{FP}_{\infty}

), and that when

r

is not a proper power, then the monoid has geometric and cohomological dimension at most

2

. The first of these results, resolves an important case of a question of Kobayashi from 2000 on homological finiteness properties of one-relator monoids. We also show how our topological approach can be used to prove results about the closure properties of various homological and topological finiteness properties for amalgamated free products and HNN-extensions of monoids. To prove these results we introduce new methods for constructing equivariant classifying spaces for monoids, as well as developing a Bass–Serre theory for free constructions of monoids.
A survey of congruences and quotients of partially ordered sets
Authors: Williams Nicholas J.
Published: May 2024

A quotient of a poset

P

is a partial order obtained on the equivalence classes of an equivalence relation

\theta

on

P

;

\theta

is then called a congruence if it satisfies certain conditions, which vary according to different theories. The literature on congruences and quotients of partially ordered sets contains a large and proliferating array of approaches, but little in the way of systematic exposition and examination of the subject. We seek to rectify this by surveying the different theories in the literature and providing philosophical discussion on requirements for notions of congruences of posets. We advocate a pluralist approach which recognises that different types of congruence arise naturally in different mathematical situations. There are some notions of congruence which are very general, whilst others capture specific structure which often appears in examples. Indeed, we finish by giving several examples where quotients of posets appear naturally in mathematics.
Association of healthy lifestyle factors with the risk of hypertension, dyslipidemia, and their comorbidity in Korea: results from the Korea National Health and Nutrition Examination Survey 2019-2021
Authors: Kong Ji-Sook , Kim Mi Kyung
Published: May 2024

OBJECTIVES: We investigated the association of individual healthy lifestyle factors (HLFs) and their combined healthy lifestyle score (HLS) with hypertension and/or dyslipidemia.METHODS: We analyzed data from 10,693 adults aged ≥19 from the 2019 to 2021 Korea National Health and Nutrition Examination Survey. HLS was evaluated based on smoking status, alcohol consumption, body mass index (BMI), diet, and physical activity. Using logistic regression models, we estimated odds ratios (ORs) with 95% confidence intervals (CIs) to evaluate the associations of HLFs and HLS with hypertension, dyslipidemia, and their comorbidity.RESULTS: The prevalence of hypertension alone, dyslipidemia alone, and their comorbidity was 8.7%, 24.6%, and 15.0%, respectively. Multivariable models showed an inverse association of hypertension (OR, 0.37; 95% CI, 0.30 to 0.46) and dyslipidemia (OR, 0.36; 95% CI, 0.32 to 0.41) with healthy BMI. Hypertension was inversely associated with healthy alcohol consumption (OR, 0.46; 95% CI, 0.35 to 0.61) and diet (OR, 0.79; 95% CI, 0.63 to 0.99), whereas dyslipidemia was inversely associated with non-smoking (OR, 0.51; 95% CI, 0.43 to 0.60). Physical activity was inversely associated with their comorbidity (OR, 0.69; 95% CI, 0.56 to 0.85). Adherence to HLS was associated with significantly lower odds of hypertension (81%), dyslipidemia (66%), and their conditions (89%) (all ptrend<0.001). Stratified analyses consistently showed inverse associations between HLS and hypertension and/or dyslipidemia independently of demographic factors (pinteractions>0.05).CONCLUSIONS: HLFs were associated with lower risk for hypertension and/or dyslipidemia. Obesity may contribute significantly to the risk of these conditions, while relevant HLFs for individual chronic diseases may vary significantly.

Authors: Ernawati Iin , Yasin Nanang Munif , Setyopranoto Ismail , Ikawati Zullies
Published: May 2024

Objectives: Mobile health app-based interventions are increasingly being developed to support chronic disease management, particularly for epilepsy patients. These interventions focus on managing stress, monitoring drug side effects, providing education, and promoting adherence to medication regimens. Therefore, this scoping review aims to assess how mobile health applications improve epilepsy patients’ knowledge and seizure control, and to identify the features of these apps that are frequently used and have proven to be beneficial.Methods: This scoping review was conducted using scientific databases such as ScienceDirect, PubMed, and Google Scholar, adhering to the Joanna Briggs Institute guidelines. The review framework consisted of five steps: identifying research questions, finding relevant articles, selecting articles, presenting data, and compiling the results. The literature search included all original articles published in English from 2013 to 2023.Results: Among six articles that discussed mobile applications for epilepsy patients, all featured similar functionalities, including education on epilepsy management and seizure monitoring. Four of the articles highlighted behavioral interventions, such as reminder systems, designed to improve medication adherence. The remaining two articles focused on a side-effect reporting system that enabled doctors or health workers to evaluate and regularly monitor adverse effects.Conclusions: This scoping review reveals that mobile health applications employing a combination of educational and behavioral interventions for epilepsy patients significantly improve knowledge about patient self-management and medication adherence. These interventions can prevent seizures, increase awareness, enable better activity planning, improve safety, and reduce the frequency of seizures and side effects of antiepileptic drugs.

Authors: Choi Jeeyae , Woo Seoyoon , Tarte Valerie
Published: May 2024

Objectives: Health systems that apply artificial intelligence (AI) are transforming the roles of healthcare providers, including those of Doctor of Nursing Practice (DNP) providers. These professionals are required to utilize informatics knowledge and skills to deliver quality care, necessitating a high level of informatics competencies, which should be developed through well-structured courses. The purpose of this study is to assess the informatics competency scale scores of DNP students and to provide recommendations for enhancing the informatics curriculum.Methods: An online informatics course was offered to students enrolled in a Bachelor of Science in Nursing to DNP program, and their informatics competency, which includes three subscales, was evaluated. Online survey data were collected from Fall 2021 to Fall 2022 using the “Self-Assessment of Informatics Competency Scale for Health Professionals.”Results: An analysis of 127 student responses revealed that students demonstrated competence in overall informatics competency and in one subscale: “applied computer skills (clinical informatics).” They showed proficiency in the “basic computer skills” and the “role” subscales. However, they reported lower competency in managing data and integrating standard terminology into their practice.Conclusions: The findings offer detailed insights into the current informatics competencies of DNP students and can inform informatics educators on how to enhance their courses. As healthcare institutions increasingly depend on AI applications, it is imperative for informatics educators to include AI-related content in their curricula.

Published: May 2024

Data privacy questions are particularly timely in the automotive industry as—now
more than ever before—vehicles are collecting and sharing data at great speeds
and quantities. Though connectivity and vehicle-to-vehicle technologies are
perhaps the most obvious, smart city infrastructure, maintenance, and
infotainment systems are also relevant in the data privacy law discourse.

Facial Recognition Software and Privacy Law in Transportation
Technology considers the current legal landscape of privacy law and
the unanswered questions that have surfaced in recent years. A survey of the
limited recent federal case law and statutory law, as well as examples of
comprehensive state data privacy laws, is included. Perhaps most importantly,
this report simplifies the balancing act that manufacturers and consumers are
performing by complying with data privacy laws, sharing enough data to maximize
safety and convenience, and protecting personal information.

Authors: Francis Nyakeko , Malingumu Winfrida , C. Ngirwa Coletha
Published: May 2024

study was about the relationship between Occupational Stress and Job Performance among Secondary School Teachers in Mwanza, Tanzania. The study was guided by the Descriptive Correlational Design. The sample for this study was 86 out of 110 heads of schools, 340 out of 2274 teachers and 34 out of 37 Ward Officers through simple random sampling. The study used a questionnaire as source of data, which was treated through the Pearson Correlations statistical tool. Based on the findings, the study concluded that not all stress is detrimental. As revealed in this study, limited stress may act as a motivator for effective performance, enhancing alertness and productivity for individuals to survive in their working places. The existing stress in schools may call for immediate intervention since excessive stress may lead to burnout which may seriously affect the performance of employees. Therefore, schools under investigation should come up with programs for managing the stress among teachers so that teachers can be stress free and do their work under safe working relationships.
