Temporal Trends in Internal vs. External Referrals for TAVR in a Large Academic Center: Patients Characteristics and Outcomes

Background Since transcatheter aortic valve replacement (TAVR) first became approved for inoperable patients followed by high, intermediate-, and low-risk patients, referrals to TAVR centers have rapidly increased. The purpose of this study was to investigate referral patterns to a large academic TAVR center in the state of North Carolina and evaluate differences between externally and internally referred patients. Methods Data for all patients who underwent TAVR at our institution between November 2014 and March 2020 were pulled from the Transcatheter Valve Therapy Registry. The electronic medical record was used to determine the referral source. The descriptive statistical analysis was performed using Excel (Microsoft, Redmond, Washington). Results 491 patients underwent TAVR at our institution between November 2014 and March 2020. Half of the patients were referred by a cardiologist within the same health system (N = 250, 50.9%). Other referral sources included a cardiologist external to the health system (N = 210, N = 42.8%) and a surgeon or proceduralist (such as urologist, surgeon, or gastroenterologist) during the workup for another procedure (N = 26, 5.3%). Over time, there was a trend toward an increasing proportion of patients referred by a cardiologist external to our system, but this trend did not reach statistical significance (20.0% in 2014, 29.2% in 2015, 30.7% in 2016, 53.0% in 2017, 36% in 2018, 48.4% in 2019, and 56.8% in 2020, p=0.06 using the Mann–Kendall trend test). Externally referred patients were less likely to have private insurance and were more likely to have a reduced ejection fraction and had a higher mean gradient across the valve. Postprocedure, externally referred patients were more likely to have the procedure under moderate sedation and less likely to be discharged home. Conclusions This study presents the referral pattern to a large TAVR center in North Carolina. Over time, there was an increase in external referrals suggesting that TAVR is increasingly adopted as an important component of the management of aortic valve stenosis. Internally and externally referred patients have differences in baseline demographic and clinical characteristics which may have an impact on clinical outcomes.
How Strong Can We Pull? Critical Thresholds for Traction Forces on the Aortic Annulus: Measurements on Fresh Porcine Hearts

Background and Objectives: Friable or infected tissue remains a challenge in surgical aortic valve replacement. We recently described the “Caput medusae” method, in which circumferential tourniquets temporarily secure the prosthesis and are then gently knotted. Tourniquets have been shown to develop significantly less force than knots. The current study investigates the critical threshold forces for tissue damage to the aortic annulus. Materials and Methods: In 14 fresh porcine hearts, the aortic valve leaflets were removed and several pledgeted sutures were placed along the annulus at defined locations. The hearts were mounted in a self-constructed device. Incremental traction force was applied to every suture and continuously recorded. The movement of each Teflon pledget was filmed with a high-speed camera. Forces at the moment of pledget “cut-in” as well as complete “tear-out” were determined from the recordings. Results: The average threshold force was determined 9.31 ± 6.04 N for cut-in and 20.41 ± 10.02 N for tear-out. Detailed analysis showed that the right coronary region had lower threshold forces than the other regions (4.77 ± 3.28 N (range, 1.67–12.75 N) vs. 10.67 ± 6.04 N (1.62–26.00 N) for cut-in and 10.67 ± 4.04 N (5.40–18.64 N) vs. 23.33 ± 9.42 N (9.22–51.23 N) for tear-out). The findings are discussed in conjunction with the knot and tourniquet forces from our previous study. Conclusions: Even in healthy tissue, moderate forces can reach a critical level at which a Teflon pledget will cut into the annulus, while a complete tear-out is unlikely. The right coronary portion is more susceptible to damage than the remaining regions. When compared to previous data, forces during manual knotting may exceed the critical cut-in level, while rubber tourniquets may provide a higher safety margin against tissue rupture.

Energetic particle dynamics in Mercury's magnetosphere

We investigate the drift paths of energetic particles in Mercury's magnetosphere by tracing their motion through a model magnetic field. Test particle simulations solving the full Lorentz force show a quasi‐trapped energetic particle population that gradient and curvature drift around the planet via “Shabansky” orbits, passing though high latitudes in the compressed dayside by equatorial latitudes on the nightside. Due to their large gyroradii, energetic H+ and Na+ ions will typically collide with the planet or the magnetopause and will not be able to complete a full drift orbit. These simulations provide direct comparison for recent spacecraft measurements from MESSENGER. Mercury's offset dipole results in an asymmetric loss cone and therefore an asymmetry in particle precipitation with more particles precipitating in the southern hemisphere. Since the planet lacks an atmosphere, precipitating particles will collide directly with the surface of the planet. The incident charged particles can kick up neutrals from the surface and have implications for the formation of the exosphere and weathering of the surface.
Defending and refuting information sources rhetorically: The case of COVID-19 vaccination

This investigation compares how COVID-19 vaccination supporters and refusers make use of rhetorical strategies to judge the credibility of information sources in online discussion. To this end, the Aristotelian tripartite approach to rhetoric, that is, ethos, pathos and logos was utilized. The empirical findings draw on the analysis of 2257 posts submitted to Suomi24—a Finnish online discussion in May—October 2021. The findings indicate that both vaccine supporters and vaccine refusers mainly drew on the pathos- and ethos-related rhetorical strategies such as appeal to blameworthiness and ad hominem arguments while judging the credibility of information sources. Coronavirus vaccination appeared to be a highly contested topic giving rise to polarized debates, deep mistrust and mutual accusations between opposing parties. The rhetorical strategies were used to attack opponents’ views on the credibility of information sources, rather than making attempts to create mutual understanding of their value for arguments used in online discussion.
Research progress on bearing fault diagnosis with localized defects and distributed defects for rolling element bearings

In rotating machinery, rolling elements are the key members of the rolling element bearing (REB), which has tremendous application in automobiles, aerospace, ships, machinery apparatuses, and many more industrial sectors. Bearings are a significant source of various non-linear parameters which strongly affect the whole system. In the last two decades, tremendous research and approaches have been developed, considering the different parameters and faultiness for the proper understanding of the system’s non-linear behavior. This research paper summarizes the literature review on bearing fault diagnosis with localized and distributed defects for rolling element bearings with various non-linear parameters. Artificially-generated defects on the bearing races provides the vibration analysis of the system. These factors like radial clearance, unbalanced force, preload, misalignment, etc. are also considered defects in bearings. Moreover, the literature highlights some significant gaps that should be examined for future research in the condition monitoring of the mechanism.
Effectiveness of Surge Flow Irrigation In Egypt: water use efficiency in field crop production

Egypt is a country of tremendous land resources but limited water resources. The area of cultivated land is only 3.2% of the gross area. The river Nile is the main source of water. In the recent years the Government established large-scale agricultural projects in light of food security related to the population growth. Expansion of irrigated agriculture has to be predominantly realized by increasing the water use efficiency. In Egypt, the dominant irrigation method is surface irrigation, which covers approximately 83% of the irrigated areas. Surface irrigation or gravity methods are generally characterized by a low efficiency. One opportunity to increase the efficiency is to convert surface irrigation to modern irrigation systems, which are generally highly expensive for a country like Egypt. Another option to increase the efficiency of surface irrigation systems is to convert the traditional irrigation method based on continuous flow to surge flow irrigation. Surge flow irrigation is the intermittent application of water to furrows in a series of relatively short on and off time periods. This study has been carried out to demonstrate the applicability of surge flow irrigation for water saving under the short field conditions that prevail in Egypt. The results indicate that surge flow irrigation is an effective irrigation method to save water and to increase crop production.
Mathematical programming techniques for solving stochastic optimization problems with certainty equivalent measures of risk

The problem of risk-averse decision making under uncertainties is studied from both modeling and computational perspectives. First, we consider a framework for constructing coherent and convex measures of risk which is inspired by infimal convolution operator, and prove that the proposed approach constitutes a new general representation of these classes. We then discuss how this scheme may be effectively employed to obtain a class of certainty equivalent measures of risk that can directly incorporate decision maker’s preferences as expressed by utility functions. This approach is consequently utilized to introduce a new family of measures, the log-exponential convex measures of risk. Conducted numerical experiments show that this family can be a useful tool when modeling risk-averse decision preferences under heavy-tailed distributions of uncertainties. Next, numerical methods for solving the arising optimization problems are developed. A special attention is devoted to the class p-order cone programming problems and mixed-integer models. Solution approaches proposed include approximation schemes for p-order cone and more general nonlinear programming problems, lifted conic and nonlinear valid inequalities, mixed-integer rounding conic cuts and new linear disjunctive cuts.
OPTICAL COHERENCE TOMOGRAPHIC STUDY AFTER VITRECTOMY FOR DISLOCATED LENS FRAGMENTS AND/OR INTRAOCULAR LENS

Background and Aim : Posterior dislocation of lens fragments is uncommon complication of phacoemulsification. However it is associated with sight threatening sequelae. These may include intraocular inflammation, secondary glaucoma, corneal edema, cystoid macular edema, and retinal detachment. Proper management is crucial to reduce the risk of these complications. Pars plana vitrectomy with intravitreal emulsification of dislocated lens fragments is indicated. Optimal timing for intervention is controversial. This study aimed to determine clinical outcomes and optical coherence tomography (OCT) changes of prompt, early and late pars plana vitrectomy with and without the use of intravitreal ultrasonic emulsification for dislocated lens fragments and/ or IOL. Methods : Thirty five eyes of 35 patients were recruited for the study. All cases underwent pars plana vitrectomy (PPV) for dislocated nuclear fragments after complicated phacoemulsification. A control group of 85 eyes with uneventful phacoemulsification were included. The clinical outcomes were visual acuity, intraocular pressure (IOP) and postoperative complications. OCT parameters including OCT-macula, OCT-Optic nerve head (ONH), and anterior segment OCT were measured at the 1 st , the 3 rd , the 6 th , the 9 th , and 12 th months postoperatively. Results : The results illustrated that eight eyes (22.8%) had CME detected by OCT at the 3rd months, while only 5 eyes (14.3%) at the 12 th months and only 4 eyes (11.4%) had chronic CME. Conclusion: Timing of PPV is an important factor affecting clinical and in dislocated nuclear fragments and IOL. The prompt PPV was associated with the best outcome followed by the early PPV. Cases in which, intravitreal ultrasound emulsification was indicated, had poorer prognostic outcome.
IMPACT OF STORAGE AND PACKAGING CONDITIONS ON PHYSICO-CHEMICAL PROPERTIES OF DATE PASTE.

The effect of storage period (12 months) and temperature (room and refrigerated) as well as packaging media (polyethylene bags under vacuum or under atmospheric pressure) on some of the physical and chemical properties of three date varieties (Rezaiz, Barni and Khudari) paste were evaluated. Data indicates that date varieties, storage temperature and period as well as packaging media significantly (p>0.05) affected moisture, sugars contents, acidity, color, pH and hardness of date paste. Storage temperature was found to be the most significant (P>0.05) parameter effecting the physico-chemical properties of the date paste. In contrast storage media showed a significant (P>0.05) effect only on moisture, sucrose contents and acidity of the date paste. Meanwhile storage period showed a significant (P>0.05) effect only on moisture content, total solids and acidity of the date paste. of date paste prepared by four different techniques. Chemical changes associated with American date deterioration were also studied by and Schiller (1961a, b). Norman et al (1975) studied the quality changes of dates under various combination of out door and refrigerated storage conditions. Browning reaction in iraqi Zahdi dates was also examined by et al. (1985). The present study aims to evaluate the effect of storage and packaging conditions on the physio-chemical properties of date paste manufactured from three main date varieties grown in the kingdom of Saudi Arabia. support earlier research findings of Yousif et al . (1986 a&b; 1991) who found that no deleterious changes in quality attributes (color, pH and sugar content ) of the date paste when it was stored for 8 weeks at 5ºC or for 16 weeks for 25ºC. They concluded that the storage temperature and period affect color and pH of the date past. Date paste color tends to change (darkening and browning) with the increase of the storage period and or storage temperature as a result of the interaction between the reducing sugars and amino acid. Maire and Schiller (1961a) and Mohammad et al . (1985) suggested that the darkening of date paste could be attributed to the effect of both the enzymatic and non-enzymatic browning. The non-enzymatic browning is significant and more dependent on temperature than on moisture content or water activity (aw) level (Al-juhaimi, 2001).
Medicolegal Examination of Sexual Assault Cases. A Retrospective Study.

Background: Sexual assault is any sexual action submitted against someone without their assent or against people who cannot give a legitimate assent. Sexual assaults can happen to anybody at whatever age, at any place, whenever. Aim of the work: to assess sexual assaults within Fayoum governorate, Egypt, and know the elements of this significant public health concern. Methods: This is a retrospective study of sexual assault cases examined by the forensic medicine authority, Fayoum governorate, Egypt, from January 2013 to December 2017. Sociodemographic data of the victim and assailants and information about the assault were recorded. Results: The study recorded 164 cases. The victim's age was commonly presented in the second decade of life as 45%. Females were higher than males. The perpetrator's age was widely shown in the third decade of life as 44%. A known person to the victim, either friend or neighbour, was the widely presented form of the relation of the perpetrator to the victim (53.7%). Anal sexual assaults or sodomy was the dominant form of assault (53.7%), followed by vaginal assaults or rape (41.5%). The time of examination of the victim after the assault was commonly one week (58.5%). At the same time, 41.5% of victims were examined for more than one week. The local genital examination findings were positive in (51.2%) of the victims. A highly significant difference was found between the victims' age and victims' gender, type of sexual assault, perpetrator age, and type of penetration. Conclusion: Most assaulted males were in their first decade of life, while most assaulted females were in the second and third decades. The results conclude that our sons and daughters could not be secure even among their most treasured ones.
Relating Vertical Velocity and Cloud/Precipitation Properties: A Numerical Cloud Ensemble Modeling Study of Tropical Convection

Fundamental relationships exist between cloud and precipitation development and their dynamic processes. Latent heat released by cloud/precipitation formation affects cloud vertical motions, which in turn affect convective cloud development. Here, a cloud‐resolving model is used to relate cloud properties and latent heating with cloud drafts using 15‐day simulations for an oceanic and continental environment. The results show condensation, deposition, and freezing occur mainly in moderate (3–5 m s−1) to strong (>10 m s−1) updrafts, evaporation and sublimation mainly in weak (1–2 m s−1) to moderate downdrafts, and melting in moderate updrafts and downdrafts. Active updrafts cover only a small percentage of the model domain but contribute significantly to the latent heat release and are associated with large proportions of the hydrometeors. Active updrafts with vertical velocities exceeding 1 and 2 m s−1 account for more than 75% and 50%, respectively, of the condensation, deposition, and freezing in both the oceanic and continental cases. However, active downdrafts with vertical velocity magnitudes exceeding |1 m s−1| account for less than 40% and 25%, respectively, of the evaporation and sublimation. More evaporation and sublimation than condensation and deposition occur in the inactive cloud regions. Sensitivity tests are also conducted to assess the impact of model grid spacing (1,000 m vs. 250 m) and microphysical schemes (3 ice classes vs. 4 ice classes) on latent heat release and hydrometeor amount. The results show that model resolution had more impact than the microphysics on the simulated cloud properties in both cases.

Diffuse Radio Recombination Line Emission on the Galactic plane

A full-sky free-free template is increasingly important for the high-sensitivity Cosmic Microwave Background (CMB) experiments, such as Planck. On the Galactic plane, where free-free estimations from Halpha measurements become unreliable, Radio Recombination Lines (RRLs) can be used to determine the thermal brightness temperature unambiguously with no dust contamination. RRLs are a powerful tool for the diagnostic of the interstellar medium, tracing the ionised component, its electron temperature, velocity and radial distributions.This thesis describes the investigation of the ionised emission from HII regions and diffuse gas along the Galactic plane using RRLs, with the aim of providing a map of the free-free emission to complement the high latitude Halpha observations. Measuring the free-free emission on the Galactic plane is of great importance to understand and characterise other Galactic emission components: synchrotron, anomalous dust and thermal dust emission.The fully-sampled HI Parkes All-Sky Survey and associated deep Zone of Avoidance Survey are re-analysed to recover extended RRL emission. They include three RRLs (H166alpha, H167alpha and H168alpha) at frequencies near 1.4 GHz. A data cube covering l=20 degree to 44 degree and |b| < 4 degree is constructed of RRL spectra with velocity and spatial resolution of 20 km/s and 14.8 arcmin, respectively. Well-known HII regions are identified as well as the diffuse RRL emission on the Galactic plane.In order to convert the integrated RRL emission into a free-free brightness temperature a value of the electron temperature (Te) of the ionised gas is needed. Using the continuum and line data from the present survey, the variation of Te with Galactocentric radius was derived for the longitude range l=20 degree to 44 degree, with a mean Te on the Galactic plane of 6000 K. The derived Te variation was used to obtain the first direct measure of the free-free brightness in this region of the Galactic plane. Subtraction of this thermal emission from the total continuum at 1.4 GHz leaves the first direct measurement of the synchrotron emission. A narrow component of width 2 degree is identified in the synchrotron latitude distribution.Determining the free-free and synchrotron emission in this region of the Galactic plane identifies the anomalous microwave component, when combined with WMAP and IRIS data. The results are in agreement with models of small spinning dust grains.
Real-Time Fault Detection and Identification for MMC Using 1-D Convolutional Neural Networks

Automated early detection and identification of switch faults are essential in high-voltage applications. Modular multilevel converter (MMC) is a new and promising topology for such applications. MMC is composed of many identical controlled voltage sources called modules or cells. Each cell may have one or more switches and a switch failure may occur in anyone of these cells. The steady-state normal and fault behavior of a cell voltage will also significantly vary according to the changes in the load current and the fault timing. This makes it a challenging problem to detect and identify such faults as soon as they occur. In this paper, we propose a real-time and highly accurate MMC circuit monitoring system for early fault detection and identification using adaptive one-dimensional convolutional neural networks. The proposed approach is directly applicable to the raw voltage and current data and thus eliminates the need for any feature extraction algorithm, resulting in a highly efficient and reliable system. Simulation results obtained using a four-cell, eight-switch MMC topology demonstrate that the proposed system has a high reliability to avoid any false alarm and achieves a detection probability of 0.989, and average identification probability of 0.997 in less than 100 ms.
