Clinical and Basic Cardiology

The cost of diagnostic and therapeutic procedures in patients with acute myocardial infarction (AMI) during hospitalization was determined using both the Diagnosis Related Group (DRG) and Process Related Group (PRG) systems. This cost-analysis system was planned and performed to estimate the cost of medical and non-medical staff involved in patient care and the cost of commisurables. In a 3 month period, 45 patients discharged with diagnosis of AMI, equivalent to 410 code ICD-9-CM, were enrolled in the study. Data collected were then elaborated and costs for each DRG were derived. The mean cost sustained for patient with AMI was 3062,32 ECU with a maximum of 8949,50 ECU for DRG 112 and a minimum of 1740,11 ECU for DRG 123. Our data suggest that, in patients with AMI a deep discrepancy between the DRG reimbursements and the “real” cost, for example for DRG 112 (a discrepancy equivalent to 166 %), exists. The cost difference is essentially related to different procedures involved in medical care; it follows that global cost of patients with AMI is primarily related to PRG cost and is largely independent from other components. These results prove that therapeutic strategies are very important to determine cost for each DRG and that the cost for each DRG can change in relation to PRG performed and to progress of the disease. The utilization of DRG and PRG systems appear to be an essential tool to build up a system in which not only efficiency but also quality of care are evaluated. J Clin Basic Cardiol 2000; 3: 23–8.
Magnetodynamics Effects of Edge Taper on Domain Wall Structure and Current-Driven Walker Breakdown in a Ferromagnetic Thin Film Wire

— Domain walls in a ferromagnetic thin ﬁlm wire with rectangular cross section adopt transverse wall (TW) or vortex wall (VW) geometries depending on the magnetic material and the wire width and thickness. However, experimentally wires can have a trapezoidal cross section if they are made by liftoff using an undercut resist proﬁle. Micromagnetic modeling shows that tapering of the wire not only promotes the formation of a TW over a VW, but also increases the critical current value and the domain wall velocity at which Walker breakdown occurs, providing a potential route to higher speed domain wall devices.
Cauchy problem for

In this paper, we examine the existence and uniqueness of solutions under the traveling wave forms for a free boundary Cauchy problem of space-fractional Jordan-Moore-Gibson-Thompson equations of nonlinear acoustics, which describe sound propagation in thermo-viscous elastic terms. It does so by applying the properties of Schauder’s and Banach’s fixed point theorems, while Caputo’s fractional derivative is used as the differential operator. For application purposes, some examples of explicit solutions are provided to demonstrate the usefulness of our main results.
Audit Quality & Earnings Management of Listed Manufacturing Firms in Nigeria

This research project looked at what happens to earnings management and audit quality in publicly traded Nigerian manufacturing companies between 2012 and 2022. The purpose of this research was to examine the relationship between earnings management proxied by discretionary accruals and audit firm size, audit fees, auditor industry specialty, and auditor tenure. All 21 firms operating in the consumer goods industry were considered part of the study's population, with 12 of those firms serving as the study's samples. The analysis relied on secondary data gathered from the firms' annual reports over the time frame. In this case, we used an ex-post Factor layout. Information was analyzed using STATA Version 16 and various regression methods. At the 5% significance level, the regression result showed that company size (Big 4), audit fees, auditor industry specialty, and audit tenure all had a substantial and favorable influence on earnings management. The study recommend that manufacturing industries in Nigeria should hire the Big4, and as well adhere strictly to the mandatory rotation policy of auditors. The study further recommend that higher fees should be paid to auditors which will be commensurate with the audit engagement.
Modeling and gait control of a quadruped robot

Generating dynamically stable gaits for legged robots is still a challenging task. Walking quadruped robots can easily stand in a stable position, the difficulty lies within the walking algorithm. Four legged animals have different gaits for different speeds, e.g. crawl, trot, pace and gallop. The generation of fast and stable walking motions requires algorithms that can take into account the dynamical effects and stability issues. A dynamical model of a quadruped robot can be used for generating new motions, with advanced algorithms, e.g. reinforcement learning or evolutionary algorithms. In this project a multi-body dynamical model is designed of the four legged robot from Sony, the ERS-7 Aibo. Several dynamical parameters were not publicly available and had to be estimated. The implemented model was compared with the real robot, using a stable walking gait. The result shows that the model represents the real robot gait accurately.
Dense array recordings in the San Bernardino Valley of landers-big bear aftershocks: Basin surface waves, Moho reflections, and three-dimensional simulations

Fourteen GEOS seismic recorders were deployed in the San Bernardino Valley to study the propagation of short-period (T ≈ 1 to 3 sec) surface waves and Moho reflections. Three dense arrays were used to determine the direction and speed of propagation of arrivals in the seismograms. The seismograms for a shallow (d ≈ 1 km) M 4.9 aftershock of the Big Bear earthquake exhibit a very long duration (60 sec) of sustained shaking at periods of about 2 sec. Array analysis indicates that these late arrivals are dominated by surface waves traveling in various directions across the Valley. Some energy is arriving from a direction 180° from the epicenter and was apparently reflected from the edge of the Valley opposite the source. A close-in aftershock (Δ = 25 km, depth = 7 km) displays substantial short-period surface waves at deep-soil sites. A three-dimensional (3D) finite difference simulation produces synthetic seismograms with durations similar to those of the observed records for this event, indicating the importance of S-wave to surface-wave conversion near the edge of the basin. Flat-layered models severely underpredict the duration and spectral amplification of this deep-soil site. I show an example where the coda wave amplitude ratio at 1 to 2 Hz between a deep-soil and a rock site does not equal the S-wave amplitude ratio, because of the presence of surface waves in the coda of the deep-soil site. For one of the events studied (Δ ≈ 90 km), there are sizable phases that are critically reflected from the Moho (PmP and SmS). At one of the rock sites, the SmS phase has a more peaked spectrum that the direct S wave.
Fair Deep Reinforcement Learning with Generalized Gini Welfare Functions

Learning fair policies in reinforcement learning (RL) is important when the RL agent’s actions may impact many users. In this paper, we investigate a generalization of this problem where equity is still desired, but some users may be entitled to preferential treatment. We formalize this more sophisticated fair optimization problem in deep RL, provide some theoretical discussion of its difficulties, and explain how existing deep RL algorithms can be adapted to tackle it. Our algorithmic innovations notably include a state-augmented DQN-based method for learning stochastic policies, which also applies to the usual fair optimization setting without any preferential treatment. We empirically validate our propositions and analyze the experimental results on several application domains.
Maternal Androgens Increase Sibling Aggression, Dominance, and Competitive Ability in the Siblicidal Black-Legged Kittiwake (Rissa tridactyla)

Animals and plants routinely produce more offspring than they can afford to rear. Mothers can favour certain young by conferring on them competitive advantages such as a leading position in the birth sequence, more resources or hormones. Avian mothers create hatching asynchrony within a clutch and at the same time bestow the eggs with different concentrations of androgens that may enhance or counteract the competitive advantage experienced by early-hatching “core” young. In siblicidal birds, core young assume a dominant social position in the nest due to their size advantage and when threatened with starvation fatally attack subdominant later-hatching “marginal” young. A role for maternal androgens in siblicidal aggression has frequently been suggested but never tested. We studied this in the facultatively siblicidal black-headed kittiwake. We found that marginal eggs contain higher instead of lower concentrations of androgens than core eggs. Surprisingly, exposure to experimentally elevated yolk androgens increased sibling aggression and dominance, even though in nature marginal eggs never produce dominant chicks. We propose the “adoption facilitation hypothesis” to explain this paradox. This cliff-nesting colonial species has a high adoption rate: ejected marginal kittiwake chicks frequently fall into other nests containing chicks of similar or smaller size and exposure to yolk androgens might help them integrate themselves into a foster nest.
Vortex states in a PbTiO 3 ferroelectric cylinder

The past decade’s discovery of topological excitations in nanoscale ferroelectrics has turned the prevailing view that the polar ground state in these materials is uniform. However, the systematic understanding of the topological polar structures in ferroelectrics is still on track. Here we study stable vortex-like textures of polarization in the nanocylin-ders of ferroelectric PbTiO 3 , arising due to the competition of the elastic and electrostatic interactions. Using the phase-field numerical modeling and analytical calculations, we show that the orientation of the vortex core with respect to the cylinder axis is tuned by the geometrical parameters and temperature of the system.
Pancreaticoduodenal Artery Aneurysm: A Rare Cause of Hemorrhagic Shock in Full Well-Being Patient

Hemorrhagic shock from PDA rupture is rare but with poor prognosis. Common presentation in the cases of acute spontaneous rupture of PDa are very sneaky. For this reason, about 49% of these patients died. Few cases are described in the literature. We described a 46 years old healthy patient that arrive in emergency per subacute abdominal pain and showed signs of hemorrhagic shock shortly after. Despite absence of precise guidelines of diagnosis and management, different experiences reported, had in common: (A) rapid resuscitation and transfer to the operating room (angiographic or surgical), (B) rapid control of the bleeding site (C) determination of exact cause of bleeding, and (D) definitive treatment by obliteration, excision, or both.
Delirium in Adults With COVID-19 – Related Acute Respiratory Distress Syndrome Comparison With Other Etiologies

Background and Objectives Neurologic complications have been associated with COVID-19, including delirium. Such complications have been reported to be frequent among intensive care unit (ICU)-admitted patients. We hypothesized that the rate of neurologic complications would be higher in COVID-19 associated acute respiratory distress syndrome (ARDS) than those who develop ARDS from a di ﬀ erent cause.
Sequential Ice Hockey Events Generation using Generative Adversarial Network ⋆

We have generated events and coordinates that lead to a hockey goal in this project. Swedish Hockey League data from season 2020-21 for twenty matches provided by Sportlogiq were used that contain event data of those matches. We used TimeGAN to generate event data. TimeGAN learns the distribution of the original time-series data and creates a synthetic version of it. After that, we showed which events led to a goal from the synthetic data. We used principal component analysis (PCA) plots to show the original and synthetic data distributions as a qualitative evaluation. Also, we have used a sequence prediction model to test the synthetic data quantitatively. We compared the synthetic data quality with another two GAN models.
Exploring Muslim College Students' Experiences: Implications for Appropriate Integration of Secular and Madrasah Education for Academic Achievement and Personal Development

: The five (5) Muslim college students' experiences are examined in this study along with how these experiences affect their achievement and development in both secular and madrasah education. The results of the data analysis, interpretation, and findings' implications shed light on the benefits of pursuing both secular and madrasah education. Integrating academic knowledge with religious teachings and developing critical thinking abilities, the merging of these two educational approaches delivers a comprehensive learning experience. Participants emphasized the value of upholding Islamic teachings and performing religious obligations, which serve as incentives for pursuing education in both secular and madrasah contexts. The study also emphasizes the value of madrasah education in maintaining Islamic knowledge, developing morals and spirituality, fostering a sense of self, and strengthening communities. The challenges faced by Muslim college students are also discussed, along with the coping mechanisms used to get beyond these barriers, including time management, academic achievement, and personal hardships. The study emphasizes the comprehensive strategy of integrating secular and madrasah education, which helps the improvement of society and the overall development of people.
AUTOMATIC SPEECH RECOGNITION OF GUJARATI DIGITS USING WAVELET-BASED FEATURES IN GAUSSIAN MIXTURE MODELS AND HIDDEN MARKOV MODELS

In this research, we employ Wavelet-based feature vectors in Hidden Markov Models to achieve automatic recognition of isolated Gujarati speech. To do this, we first created a Gujarati voice dataset of numbers one to ten uttered by eight individuals. The dataset was then enlarged utilizing data augmentation techniques. Wavelet-based feature vectors, Mel-Frequency Discrete Wavelet Coefficients (MFDWC), were then employed for dimensionality reduction and vital feature extraction. These feature vectors were used to compute the observation probabilities using Gaussian Mixture Models (GMM). Further, these probabilities were used in Left-to-right whole-word Hidden Markov Models (HMM) with a different number of states. The Baum-Welch algorithm was used to train the HMM parameters. Finally, the trained HMM was used to classify the test speech. Using confusion matrices and several classification metrics, the classification accuracy of the original and augmented datasets is compared.
Edinburgh Research Explorer A Dataset for Persistent Multi-Target Multi-Camera Tracking in RGB-D

Video surveillance systems are now widely deployed to improve our lives by enhancing safety, security, health monitoring and business intelligence. This has motivated extensive research into automated video analysis. Neverthe-less, there is a gap between the focus of contemporary research, and the needs of end users of video surveillance systems. Many existing benchmarks and methodologies focus on narrowly deﬁned problems in detection, tracking, re-identiﬁcation or recognition. In contrast, end users face higher-level problems such as long-term monitoring of identities in order to build a picture of a person’s activity across the course of a day, producing usage statistics of a particular area of space, and that these capabilities should be robust to challenges such as change of clothing. To achieve this effectively requires less widely studied capabilities such as spatio-temporal reasoning about people identities and locations within a space partially observed by multiple cameras over an extended time period. To bridge this gap between research and required capabilities, we propose a new dataset LIMA that encompasses the challenges of monitoring a typical home / ofﬁce environment. LIMA contains 4.5 hours of RGB-D video from three cameras monitoring a four room house. To reﬂect the challenges of a realistic practical application, the dataset includes clothes changes and visitors to ensure the global reasoning is a realistic open-set problem. In addition to raw data, we provide identity annotation for benchmarking, and tracking results from a contemporary RGB-D tracker – thus allowing focus on the higher level monitoring problems.
Information Flow in Secure Contexts £

Information flow security in a multilevel system aims at guaranteeing that no high level information is revealed to low level users, even in the presence of any possible malicious process. This requirement could be stronger than necessary when some knowledge about the environment (context) in which the process is going to run is available. To relax this requirement we introduce the notion of secure contexts for a class of processes. This notion is parametric with respect to both the observation equivalence and the operation used to characterize the low level view of a process. As observation equivalence we consider the cases of weak bisimulation and trace equivalence. We describe how to build secure contexts in these cases and we show that two well-known security properties, named BNDC and NDC, are just special instances of our general notion.

Neurodevelopmental delay in pediatric HIV/AIDS: current perspectives

: The effects of HIV on the developing nervous system of perinatally HIV (PHIV)- infected children are substantial, yet poorly understood. While the introduction of combination antiretroviral therapy (cART) reduced the prevalence of HIV encephalopathy, many cART-treated PHIV-infected children still present with neurodevelopmental delays and cognitive impairment. The underlying pathogenesis may partially differ from that in adults, as HIV not only causes direct injury to the central nervous system (CNS) but may also impede the development of the pediatric brain. Increasing evidence implies significant roles for ongoing neuroinflammation, vascular dysfunction and hypercoagulability induced by HIV despite adequate viral suppression. Subsequent manifestations of HIV in the pediatric brain include gray-matter volume reduction, white-matter lesions, and basal ganglia calcifications, but even in the absence of such macrostructural changes, the detrimental effects of HIV are clearly revealed in widespread microstructural changes, such as poorer white-matter integrity and alterations in cerebral metabolites and blood flow. Viral suppression on cART evidently does not fully protect against cerebral injury, but knowledge concerning the pharmacokinetics and toxicity of cART in the pediatric CNS is lacking. Investigations combining neuropsychological assessment, multimodal neuroimaging, and laboratory evaluation of inflammatory and neurodegenerative markers could greatly increase our understanding of the pathogenesis of HIV in the developing nervous system and improve treatment and prevention strategies. Longitudinal research will be crucial to observe the long-term consequences of CNS exposure to HIV and cART in PHIV-infected children as they survive into adulthood.
Education or Quality of Teaching? Implications for Australian Education or Quality of Teaching? Implications for Australian Democracy Democracy

: The argument being made here is that democratic life is more likely if educators actually ‘educate’, rather than comply with quality of teaching approaches as promoted by the Australian federal government. Engaging with some philosophy of education can assist educators to resist being seduced by notions such as ‘quality teaching’, ‘evidence-based’ practices and ‘impact’ and to exercise the intellectual and political resolve necessary to ensure educational practices promote democracy (Biesta, 2010a) and are not surrendered to the control of non-educators. Blake et al. (2000, p. xiii) identify that philosophy is usually avoided in discussions regarding quality, evidence-based approaches and accountability because bureaucrats are “intolerant of philosophical debate”. By drawing largely upon the works of Dewey and his notions of education, democracy and the science of education, it is argued that what is needed is for teacher-educators to focus on ‘educating’ teachers, as professionals, to be critically scientific and democratic.
Streaks in Earnings Surprises and the Cross-Section of Stock Streaks in Earnings Surprises and the Cross-Section of Stock Returns Returns

The gambler’s fallacy (Rabin, 2002) predicts that trends bias investor expectations. Consistent with this prediction, we ﬁnd that investors underreact to streaks of consecutive earnings surprises with the same sign. When the most recent earnings surprise extends a streak, post-earnings announcement drift is strong and signiﬁcant. In contrast, the drift is negligible following the termination of a streak. Indeed, streaks explain about half of the post-earnings announcement drift in our sample. Our results are robust to more general deﬁnitions of trends than streaks and a battery of control variables including the magnitude of earnings surprises and their autocorrelation. Overall, post-earnings announcement drift has a signiﬁcant time-series component that is consistent with the gambler’s fallacy.
Quaternary subglacial processes in Switzerland : geomorphology of the plateau and seismic stratigraphy of Western Lake Geneva

Les processus sous-glaciaires quaternaires dans l'avant-pays suisse sont etudies ici au moyen de la geomorphologie et de la sismo-stratigraphie. L'etude geomorphologique commence par une modelisation du substat rocheux de la Suisse occidentale mettant en evidence un reseau anastomose de vallees-tunnel sur le plateau. Puis, sur la base de modeles numeriques de terrain, les formes glaciaires heritees des dernieres glaciations (drumlins rocheux, drumlins, ribbed moraines, eskers et moraines) sont cartographiees et analysees. Ceci constitue la premiere mention de ribbed moraines sous la calotte alpine. La sismo-stratigraphie du Petit-Lac (partie occidentale du Leman) est basee sur de nombreux profils sismiques haute-resolution. 12 unites sont differenciees. La plupart d'entre elles sont des tills deposes sous le glacier flottant, a mesure que l'epaisseur de glace diminuait. De nombreuses oscillations du front glaciaire sont reconnues. L'etude revele egalement la presence d'eskers associes a un eventail pro-glaciaire.
