Observations from the post-COVID-19 cardiovascular examination record

Objective: To evaluate the prevalence and characteristics of “de novo” cardiovascular findings (DNCFs) among post-COVID-19 patients based on a basic cardiovascular diagnostic procedure. Moreover, to describe the patients’ results obtained by means of different diagnostic methods, to determine the clinical variables associated with DNCFs during the examination and, finally, to find out the diagnostic value of different data from medical records (MRs). Materials and methods: Patients aged > 18 years who had COVID-19 either at the hospital or at home were evaluated by clinical interviews, physical examination, electrocardiogram (EKG), echocardiogram, routine lab tests and cardiac biomarkers between 30 and 120 days after discharge. A total of 246 patients (age: 52 ± 13 years; women: 48 %; mild, moderate and severe COVID-19: 37 %, 39 % and 24 %, respectively) were included in the study. Twenty-four percent of the population were asymptomatic at the time of the evaluation. In those patients who developed symptoms, dyspnea was the most frequent one (28 %). Interviews were the method with the highest index of suspicion (45 %). Physical examination, EKG, echocardiogram and biomarkers showed normal values among 61 %, 60 %, 75 % and 96 % of the patients, respectively. Results: DNCFs were found in 62 patients (25.2 %): heart rhythm disorders in 42 (17 %) and ventricular dysfunction in 20 (8 %). Five patients had coronary artery disease, six had myocarditis and two had valvular heart disease. In addition, post-COVID-19 pulmonary embolism (PE) was detected in 10 patients, six of whom (2.4 %) had to be rehospitalized. Furthermore, in a multivariate analysis, the independent predictive variables of DNCFs were prior history of chronic obstructive pulmonary disease (COPD), QTc > 440 msec, leukocytosis and intra-COVID-19 cardiovascular complication. MRs showed both low sensitivity and positive predictive value for DNCFs. Conclusions: Although DNCFs were observed in 25 % of the population, only 2 % were significant. According to the data collected from this diagnostic procedure and in this time frame, special attention should be paid to patients with prior history of COPD and/or cardiovascular complications during the acute stage and/or prolonged QTc interval. Post-COVID-19 symptoms were of limited value for the diagnosis of arrhythmias or ventricular dysfunction.
Effects of surface water interactions with karst groundwater on microbial biomass, metabolism, and production

Unearthing the effects of surface water and groundwater interactions on subsurface biogeochemical reactions is crucial for developing a more mechanistic understanding of carbon and energy flow in aquifer ecosystems. To examine physiological characteristics across groundwater microbial communities that experience varying degrees of interaction with surface waters, we investigated ten springs and a river sink and rise system in North Central Florida that discharge from 10 and/or mix with the karstic Upper Floridan Aquifer (UFA). Groundwater with longer residence times in the aquifer had lower concentrations of dissolved oxygen, dissolved and particulate organic carbon, and microbial biomass, as well as the lowest rates of respiration (0.102 to 0.189 mg O 2 L -1 d -1 ) and heterotrophic production (198 to 576 µg C L -1 d -1 ). Despite these features, oligotrophic UFA groundwater (< 0.5 mg C L -1 ) contained bioavailable organic matter that supported doubling times (14 to 62 h) and cell specific production rates (0.0485 to 0.261 pmol C cell -1 h -1 ) comparable to those 15 observed for surface waters (17 to 20 h; 0.105 to 0.124 pmol C cell -1 h -1 ). The relatively high specific rates of dissimilatory and assimilatory metabolism indicate a subsurface source of labile carbon to the groundwater (e.g., secondary production and/or chemoautotrophy). Our results link variations in UFA hydrobiogeochemistry to the physiology of its groundwater communities, providing a basis to develop new hypotheses related to microbial carbon cycling, trophic hierarchy, and processes generating bioavailable organic matter in karstic aquifer
Biochemical, sensory and storage ability assessment of different tamarind drink formulations

Fruits belong to an emergent class of food items that serve the human diet with nutritive requirements together with vitamins and minerals that are essential for normal daily life and body functions. The study was conducted to prepare Tamarind drinks by using fully ripen Tamarind fruit. Tamarind fruit was processed into pulp analyzed for their moisture, ash, TSS, pH, acidity, vitamin C, reducing sugar, non-reducing sugar and total sugar content. Chemical composition of formulated tamarind drinks, shelf-life and consumer acceptance were investigated. Chemical analysis showed that the Vitamin C content of the tamarind drinks decreased greatly (8.96-5.45 mg/100g) comparatively to other samples during the storage period. Acidity and reducing sugar were increased (0.12-0.144%) and (23.75-24.37%) progressively whereas pH and non-reducing sugar were slightly decreased (3.35-3.25) and (21.0-20.44%) respectively. Storage stability of the products was studied for ﬁfty days with ten days intervals and the result showed that all samples were in good condition but after one month a little bit of faded color was found at end of the storage period. The formulation contains a processed pulp of TSS 8 ◦ B secured the highest score on sensory evaluation and showed the best acceptance by consumers. This research arises that tamarind fruit can be formulated to as tamarind drinks which increase the value addition of tamarind fruits.
Corn and soybean response to sulfur application on Iowa soils

Historically sulfur (S) application has not been recommended on Iowa soils for corn and soybean production. Prior research has not determined a consistent need for S fertilization in Iowa, with field research indicating no corn or soybean yield response to applied S at virtually every site studied (Thorup and Leitch, 1975; Webb, 1978; Alesii, 1982; Killorn, 1984; Sexton et al., 1998; Mallarino et al., 2000). The soil supply, in combination with sources such as manure and atmospheric deposition has apparently met corn and soybean S needs. Sulfur deficiencies have been reported over the years in various areas of the Midwestern USA, examples including Alway (1940), Hoeft and Walsh (1970), Thorup and Leitch (1975), Rehm (1976), Hoeft (1980), Hoeft et al. (1985), Stecker et al. (1995), and Lamond et al. (1997). However, positive yield responses are often infrequent, for example Hoeft et al. (1985) and Stecker et al. (1995). Responsive sites are most often noted as eroded or low organic matter-coarse textured soils.
Multi-THz Bands Large-Scale Fading Characterization and Path Loss Prediction Based on Environment Features

Terahertz (THz) communications are envisioned as one of the promising technologies to enable ultra-broadband 6G systems. One fundamental challenge when moving to new spectrum is to understand the science of radio propagation and propose an accurate and eﬀective channel prediction method for predicting the signal coverage. In this paper, we ﬁrst conduct extensive VNA-based wideband radio propagation measurements at 220 GHz in indoor hallway and lobby environments and at 280 GHz in an indoor laboratory environment. Omnidirectional and best directional path loss are analyzed and modeled by empirical single-band and multi-band path loss models. Besides, propagation statistics such as Rician K-factor (KF) and root mean square (RMS) delay spread (DS) are modeled by Weibull distribution and lognormal distribution, respectively, and two-slope model is proposed to analyze the relationship of the KF, RMS DS and distance in various scenarios. Numerical results demonstrate that large-scale close-in model in this paper is simpler and more physically-based compared to ﬂoating-intercept model. In particular, path loss prediction method based on environment features is proposed, which can predict path loss directly by utilizing random forest method, and the propagation environment are deﬁned and extracted by scatterer features and related features of Tx and Rx. The performance of the proposed model is better than that of empirical path loss models. The measured results not only enrich the datasets of indoor THz channel propagation, also can guide communication systems, network planning and deployment for 6G and beyond
Reconciling Top-down and Bottom-up Methane Emissions Estimates in the Delaware Basin

: Methane is a greenhouse gas and identified as a key driver of near-term climate change. Bottom-up approaches estimate annual methane loss from US natural gas production and transport at 6 Tg, but recent studies suggest this may be an underestimate. To investigate this possibility, an equipment-based emissions inventory, using EPA emission factors, was developed to calculate methane emissions from oil and gas operations in the Delaware Basin, USA. Emission factors and activity data were then updated using contemporary and region-specific measurement data. The original inventory estimated emissions at 315 Gg CH 4 y -1 (gas production-normalized rate of 0.6% loss), while the updated inventory estimated emissions of 1,500 Gg CH 4 y -1 (2.8% loss). The largest changes resulted from large fugitive emissions from oil production (+430 Gg CH 4 y -1 ), updating maintenance activity emissions (+214 Gg CH 4 y -1 ), considering flaring inefficiency (+174 Gg CH 4 y - 1 ), and the inclusion of associated gas venting (+136 Gg CH 4 y -1 ). This study suggests that a systematic underestimate probably exists in current bottom-up inventories and identifies sources currently missing or may be incorrect. We also strongly recommend that emission factors should be validated through direct comparison against measurement campaigns that include long-tail distributions typical of oil and gas activities.
Behavioral and Subjective Performance with Digital CROS/BiCROS Hearing Instruments

The efficacy of wireless digital CROS and BiCROS hearing instruments was determined for 12 adults with single-sided deafness (SSD) and 12 adults with asymmetrical hearing loss. Participants’ speech-recognition performance in noise (with a loudspeaker arrangement that was disadvantageous) significantly improved when using the CROS/BiCROS devices as compared to the unaided condition. Ratings on three subjective questionnaires yielded positive average CROS/BiCROS ratings from the participants in this study. Given the results of the present study and results from previous investigations, these instruments may be considered on a trial basis for individuals with SSD or asymmetrical hearing loss.
DisabilityDisorders: Association with Clinical Associated - Immunoglobulin G Antibody Oligodendrocyte Glycoprotein Glymphatic System Dysfunction in Myelin

BACKGROUND AND PURPOSE: Impaired glymphatic function has been suggested to be implicated in the pathophysiology of MS and aquaporin-4 immunoglobulin G-positive neuromyelitis optica spectrum disorder. This study aimed to investigate the interstitial ﬂ uid dynamics in the brain in patients with myelin oligodendrocyte glycoprotein antibody disorders (MOGAD), another demyelinating disorder, using a noninvasive imaging technique called the diffusivity along the perivascular space (ALPS) index. MATERIALS AND METHODS: A prospective study was conducted on 16 patients with MOGAD in remission and 22 age-and sex-matched healthy control subjects. MR imaging was performed using a 3T scanner, and the ALPS index was calculated using diffusion MR imaging data with a b-value of 1000 s/mm 2 . The ALPS index and gray matter volumes were compared between the 2 groups, and these parameters were correlated with the Expanded Disability Status Scale. RESULTS: The mean ALPS index of patients with MOGAD was signi ﬁ cantly lower than that of healthy controls (Cohen d ¼ 0.93, false discovery rate – corrected P ¼ .02). The lower mean ALPS index was signi ﬁ cantly associated with a worse Expanded Disability Status Scale score (Spearman r ¼ (cid:2) 0.51; 95% CI, (cid:2) 0.85 to (cid:2) 0.02; P ¼ . 03). However, cortical volume and deep gray matter volume were not signi ﬁ cantly different between the 2 groups, and they were not correlated with the Expanded Disability Status Scale. CONCLUSIONS: This study suggests that patients with MOGAD may have impaired glymphatic function, as measured by the ALPS index, which is associated with patient disability. Further study is warranted with a larger sample size
A nonhydrostatic oceanic regional model, ORCTM v1, for internal solitary wave simulation

Abstract. The Oceanic Regional Circulation and Tide Model (ORCTM), including a nonhydrostatic dynamics module which can numerically reproduce internal solitary wave (ISW) dynamics, is presented in this paper. The performance of a baroclinic tidal simulation is also examined in regional modeling with open boundary conditions. The model control equations are characterized by three-dimensional and fully nonlinear forms considering incompressible Boussinesq fluid in Z coordinates. The pressure field is decomposed into the surface, hydrostatic, and nonhydrostatic components on the orthogonal curvilinear Arakawa-C grid. The nonhydrostatic pressure determined by the intermediate velocity divergence field is obtained via solving a three-dimensional Poisson equation based on a pressure correction method. Model validation experiments for ISW simulations with the topographic change in the two-layer and continuously stratified ocean demonstrate that ORCTM has a considerable capacity for reproducing the life cycle of internal solitary wave evolution and tide–topography interactions.

An eﬀective formulation for estimating wetland surface energy ﬂuxes from weather data

In modelling evapotranspiration, the need for land surface variables including ground heat ﬂuxes (G), surface temperature (Ts), surface relative humidity (RHs) and surface resistance often present a challenge due to land heterogeneity and limited measurements. This study introduces a simple formulation rooted in the shared physical basis of the maximum entropy model (MaxEnt), the Relative Humidity at Equilibrium (ETRHEQ) method, and the Surface Flux Equilibrium (SFE) method, and it estimates sensible (H) and latent ﬂuxes (LE) in wetlands without requiring land surface variables or site-speciﬁc calibration, except for an assumed vegetation height. Further, it eﬀectively estimates LE from half-hourly to monthly scales in FLUXNET and AmeriFlux wetland sites. While its performance in estimating H is less satisfactory due to loosely constrained boundary conditions, it shows promising potential for simultaneously and precisely estimating LE, H, G, Ts, and RHs from weather data in various ecosystems.
A Parameterization of Turbulent‐Scale and Mesoscale Orographic Drag in a Global Atmospheric Model

The effect of drag due to subgrid orography with turbulent scales, the so‐called turbulent orographic form drag, is introduced by revising the surface exchange coefficient for momentum, to alleviate the overall positive bias in wind speed in the near‐surface and low‐level troposphere over land. Also, the excessive flow‐blocking drag, responsible for negative biases in low‐level wind speed over highly complex terrains, is abated by modifying the height of the blocked layer, which is achieved without a significant deficiency of total surface drag because of additional turbulent orographic form drag. The impact of the revised subgrid‐scale orography parameterization is investigated on the medium‐range forecast (January and July 2016) and seasonal ensemble prediction (June–August 2013 and December 2013 to February 2014) regarding stress partitioning and skill scores. With the revised subgrid‐scale orography schemes, total surface stress and its partitioning resemble those of the ERA‐Interim. Meanwhile, the turbulent (mesoscale orographic) stress is enhanced (reduced) due to the additional turbulent orographic form drag (weakened flow‐blocking drag). For the medium‐range forecast, systematic biases in near‐surface and low‐level wind speed are satisfactorily rectified by adding turbulent orographic form drag (reducing flow‐blocking drag) in the regions with positive biases across the land (negative biases over highly complex terrains) against reanalysis, as well as observation data. Seasonal simulation is also improved because the weak polar night jet and the corresponding warm pole biases are alleviated by the reductions of the orographic gravity wave and resolved wave drag, which are driven by the revised low‐level drag.
Rationality and Rhetoric in the Corporate World: The Corporate Annual Report as an Aristotelian Genre

This paper is part of a research programme into corporate annual reports. Reports do provide the information on the past performance, present state and future prospects which investors in listed companies require for the rational choices attributed to them. They also reveal the companies' responsiveness to the publics comprising the civil societies in which they are embedded. This effect requires more than strict rationality. To use Simon's distinction, the reports then entail both substantive and procedural rationalities. We argue that classical rhetoric and its recovery in the 'new rhetoric' yield useful approaches to the latter, and that annual reports comprise a genre in the rhetorical sense. We illustrate our case through generic features in the reports of the Australian-based multinational, Amcor. We suggest for future research that accounts of corporate functioning are incomplete unless they include the pre-structured interaction between companies and their publics which we have shown here through rhetoric.
Sheet---“B-value variations in the Central Chile seismic gap assessed by a Bayesian transdimensional approach”

The b-value can be used to characterize the seismic activity for a given earthquake catalog and provide information on the stress level accumulated at active faults. Here we develop an algorithm to objectively estimate variations of b-value along one arbitrary dimension. To this end, we employ a Bayesian transdimensional approach where the seismic domains will be self-defined according to information in the seismic catalog. This makes it unnecessary to prescribe the location and extent of domains, as it is commonly done. We first show the algorithm’s robustness by performing regressions from synthetic catalogs, recovering the target models with great accuracy. We also apply the algorithm to a microseismicity catalog for the Central Chile region. This segment is considered a seismic gap where the last major earthquake with shallow slip was in 1730. Our results illuminate the downdip limit of the seismogenic zone and the transition to intraslab seismicity. In the along-strike direction, low b-value coincides with the extent of locked asperities, suggesting a high-stress loading at the Central Chile seismic gap. Our results indicate the reliability of the Bayesian transdimensional method for capturing robust b-value variations, allowing us to characterize the mechanical behavior on the plate interface of subduction zones.
Numerical Investigation on Absorption Enhancement of Black Carbon Aerosols Partially Coated With Nonabsorbing Organics

This study numerically evaluates the effects of aerosol microphysics, including coated volume fraction of black carbon (BC), shell/core ratio, and size distribution, on the absorption enhancement (Eab) of polydisperse BC aggregates partially coated by organics, which is calculated by the exact multiple‐sphere T‐matrix method. The coated volume fraction of BC plays a substantial role in determining the absorption enhancement of partially coated BC aggregates, which typically have an Eab in the range of ~1.0–2.0 with a larger value for larger coated volume fraction of BC as the shell/core ratio, BC geometry, and size distribution are fixed. The shell/core ratio, BC geometry, and size distribution have little impact on the Eab of coated BC with small coated volume fraction of BC, while they become significant for large coated volume fraction of BC. The Eab of partially coated BC particles can be slightly less than 1.0 for the large BC in the accumulation mode exhibiting large shell/core ratio and small coated volume fraction of BC, indicating that the absorption shows even slight decrease relative to uncoated BC particles. For partially coated BC aggregates in the accumulation and coarse modes, the refractive index uncertainties of BC result in the Eab differences of less than 9% and 2%, respectively, while those of organics can induce larger variations with the maximum differences up to 22% and 18%, respectively. Our study indicates that accounting for particle coating microphysics, particularly the coated volume fraction of BC, can potentially help to understand the differences in observations of largely variable absorption enhancements over various regions.
The effect of task-supported and task-based teaching on the use of Russian verbs of motion

The goal of this investigation is to determine to what extent task-supported (TS) and task-based (TB) language teaching approaches are effective for learning Russian verbs of motion. To this aim, an experimental study was carried out under real classroom conditions as a part of Russian language courses at the University of ***. Participants were organised into two groups that received a TS and a TB treatment, respectively. The implementation of the didactic strategies subsumed in the design of the TB treatment by means of a Learning Management System (Moodle), the benefits and key features of which facilitate task-based instruction, are analysed. The study follows the pre-test, post-test and delayed post-test design. In the light of the results obtained, it is safe to say that the two approaches are beneficial for learning verbs of motion since both groups showed a significant improvement in all the measured aspects, that is, the correct use of verbs both in the oral and written production and in the grammar tests (fill in the blanks, multiple choice and grammaticality judgement tests). Nevertheless, the TB group performed significantly better than the TS group in the oral tasks, and in most delayed post-tests
