Marginal Bone Level and Clinical Parameter Analysis Comparing External Hexagon and Morse Taper Implants: A Systematic Review and Meta-Analysis

The goal of this systematic review was to verify the marginal bone loss (MBL) and other clinical parameters comparing external hexagon (EH) and Morse taper (MT) implants when they were evaluated within the same study. The focused question was, “For patients (P) treated with external connection (I) or Morse taper (C) dental implants, were there differences in the marginal bone crest maintenance after at least three months in occlusal function (O)”? As for the inclusion criteria that were considered, they included clinical studies in English that compared the MBL in implants with EH and MT, with follow-up of at least three months, that were published between 2011 and 2022; as for the exclusion criteria, they included publications investigating only one type of connection that analyzed other variables and did not report results for the MBL, reports based on questionnaires, interviews, and case reports/series, systematic reviews, or studies involving patients with a significant health problem (ASA Physical Status 3 and above). The PubMed/MEDLINE, Embase, and Web of Science databases were screened, and all of the data obtained were registered in a spreadsheet (Excel®). The Jadad scale was used to assess the quality of the studies. A total of 110 articles were initially identified; 11 were considered for full-text reading. Then, six articles (four RCTs and two prospective studies) met the eligibility criteria and were included in this study. A total of 185 patients (mean age of 59.71) were observed, and the follow-up ranged from 3 months to 36 months. A total of 541 implants were registered (267 EH and 274 MT). The survival rate ranged between 96% and 100% (the average was 97.82%). The MBL was compared among all periods studied; therefore, the common assessment period was the 12-month follow-up, presenting greater MBL for EH than for MT (p < 0.001). A mean MBL of 0.60 mm (95% CI 0.43–0.78) was found after the same period. BoP was reported in 5 studies and plaque index was reported in 4 (2 with more than 30%). Deep PD was observed in three studies. High heterogeneity was observed (I2 = 85.06%). Thus, within the limitation of this review, it was possible to conclude that there is higher bone loss in EH than in MT implants when evaluating and comparing this variable within the same study. However, the results must be carefully interpreted because of this review’s limited number of clinical studies, the short assessment period, and the high heterogeneity found.
Cluster-Locating Algorithm Based on Deep Learning for Silicon Pixel Sensors

The application of silicon pixel sensors provides an excellent signal-to-noise ratio, spatial resolution, and readout speed in particle physics experiments. Therefore, high-performance cluster-locating technology is highly required in CMOS-sensor-based systems to compress the data volume and improve the accuracy and speed of particle detection. Object detection techniques using deep learning technology demonstrate significant potential for achieving high-performance particle cluster location. In this study, we constructed and compared the performance of one-stage detection algorithms with the representative YOLO (You Only Look Once) framework and two-stage detection algorithms with an RCNN (region-based convolutional neural network). In addition, we also compared transformer-based backbones and CNN-based backbones. The dataset was obtained from a heavy-ion test on a Topmetal-M silicon pixel sensor at HIRFL. Heavy-ion tests were performed on the Topmetal-M silicon pixel sensor to establish the dataset for training and validation. In general, we achieved state-of-the-art results: 68.0% AP (average precision) at a speed of 10.04 FPS (Frames Per Second) on Tesla V100. In addition, the detection efficiency is on the same level as that of the traditional Selective Search approach, but the speed is higher.
Note on a Previous Paper Entitled On Adding Relations to Homotopy Groups

The object of this note is to fill a gap in the definition of, and to make certain remarks concerning a group, hr, which was introduced in H. G. (p. 421). 1 The definition should read as follows: Let r be a given group, whose elements we denote by small greek letters, and let H be an aggregate of individuals a, a-', b, b-1, *, such that a # a-', b 5 bV' etc.2 Let h(H) C F be a single-valued, but not necessarily (1 1), transformation of H in F, such that h(a-') = {h(a) }-'. We denote by hr the group generated by all pairs (a, i), to be denoted by at, with (a, 7 ' = (a-', ), subject to the relations (1.1) atbt,= brat, for each a, b C H, i, il C F, where r = th(a)t7 'n (if a = b, t = l, this reduces to at = ath(a)). We recall from H. G. the definitions of the automorphism Oi(hr) = hr. defined by
Differentiating physical and biological storage of N along an intermittent Antarctic stream corridor

In many temperate streams, biological uptake of N acts to attenuate the transport of excess N from allochthonous anthropogenic imports. Relatively few studies have determined how this N uptake relates to the magnitude of physical vs biological N storage in the stream corridor, especially for intermittent systems where allochthonous N imports are often low and N transport may only occur during brief periods of streamflow. Glacial meltwater streams in the McMurdo Dry Valleys of Antarctica provide an excellent setting to quantify autochthonous N-cycling and storage processes supported by abundant algal mats and well-connected hyporheic zones. We combined historic point-scale sediment and periphyton sample datasets with remote sensing-based modeling of periphyton coverage to estimate how much N was stored in periphyton biomass and the hyporheic zone of a 5-km long McMurdo Dry Valley stream corridor (>100,000 m2). We contextualized these N storage calculations by estimating the magnitude of annual N imports to and exports from the stream corridor based on >2 decades of streamflow and surface water data, source glacier ice cores and meltwater data, and past studies of local aeolian deposition and biological N fixation rates. We found that in this highly oligotrophic system, stream corridor-scale N storage was ∼1000× that of total annual N import or export fluxes. More than 90% of this temporarily stored N was autochthonous organic matter in the shallow (<10 cm) hyporheic zone, which acts as a reservoir that sustains N availability in the water column. Despite its location in a polar desert devoid of higher-order vegetation, area-normalized N storage (∼40 g N/m2) was greater than that reported for streams at lower latitudes (∼1–22 g N/m2). We also demonstrated that NH4+ sorption to stream sediment may be an important physicochemical N storage mechanism that responds to short-term fluctuations in streamflow and governs the mobility of inorganic N. Altogether, this research illustrates the importance of quantifying N storage within stream corridors when evaluating the significance of internal cycling and physical retention processes that modulate N availability.
Development of a Turbulent Wall-Function Based Viscous Cartesian-Grid Methodology

Despite the high cost of memory and CPU time required to resolve the boundary layer, a viscous unstructured grid solver has many advantages over a structured grid solver such as the convenience in automated grid generation and vortex capturing by solution adaption. In present study, an unstructured Cartesian grid solver is developed on the basis of the existing viscous solver, NASCART-GT. Instead of a cut-cell approach, an immersed boundary approach is applied with ghost cell boundary condition, which can be easily applied to a moving grid solver. The standard k-e model by Launder and Spalding is employed for the turbulence modeling, and a new wall function approach is devised for the unstructured Cartesian grid solver. In this study, the methodology is validated and the efficiency of the developed boundary condition is tested in 2-D flow field around a flat plate, NACA0012 airfoil, and axisymmetric hemispheroid.
The Moho Architecture and Its Role for Isostasy—Insights From the Lofoten‐Vesterålen Rifted Margin, Norway

The crustal structure of the Nordland and Troms region, Norway, has received growing scientific attention because (a) the region is one of the most seismically active areas of mainland Norway, and (b) there are differing interpretations of the crustal structure but none of the proposed models simultaneously satisfy gravity, topography and crustal isostasy. At the core of the puzzle is the Lofoten‐Vesterålen archipelago, which exhibits considerable variations in crustal thickness, seemingly inconsistent with the topographic expression along this geomorphic structure. The prevalent view has been that the crust beneath the southern Lofoten is extremely thin (∼20 km). This has recently been disputed. Here, we address this debate by producing new lithospheric models in the region from joint inversion of receiver functions and P‐wave polarizations at 62 seismic stations. Our results are consistent with the regional trends from other models, including a shallow Moho in the southern Lofoten. Moreover, our results detect a low‐velocity layer in the uppermost mantle, which appears to be highly relevant to isostasy in the region. We conclude that the crustal structure in the region may not be as controversial as the recent debate suggested. What appears more urgent to understand is how the concept of isostasy is defined, and how it relates to the layered structure of the lithosphere. In particular, our findings emphasize the importance of conceptualizing the Moho as a transition zone with considerable thickness and internal structural variations, rather than a simple velocity discontinuity.
The Cryogenic Anti-Coincidence detector for ATHENA X-IFU: pulse analysis of the AC-S7 single pixel prototype

The ATHENA observatory is the second large-class mission in ESA Cosmic Vision 2015-2025, with a launch foreseen in 2028 towards the L2 orbit. The mission addresses the science theme “The Hot and Energetic Universe”, by coupling a high-performance X-ray Telescope with two complementary focal-plane instruments. One of these is the X-ray Integral Field Unit (X-IFU): it is a TES based kilo-pixel order array able to provide spatially resolved high-resolution spectroscopy (2.5 eV at 6 keV) over a 5 arcmin FoV. The X-IFU sensitivity is degraded by the particles background expected at L2 orbit, which is induced by primary protons of both galactic and solar origin, and mostly by secondary electrons. To reduce the background level and enable the mission science goals, a Cryogenic Anticoincidence (CryoAC) detector is placed < 1 mm below the TES array. It is a 4- pixel TES based detector, with wide Silicon absorbers sensed by Ir:Au TESes. The CryoAC development schedule foresees by Q1 2017 the delivery of a Demonstration Model (DM) to the X-IFU FPA development team. The DM is a single-pixel detector that will address the final design of the CryoAC. It will verify some representative requirements at single-pixel level, especially the detector operation at 50 mK thermal bath and the threshold energy at 20 keV. To reach the final DM design we have developed and tested the AC-S7 prototype, with 1 cm2 absorber area sensed by 65 Ir TESes. Here we will discuss the pulse analysis of this detector, which has been illuminated by the 60 keV line from a 241Am source. First, we will present the analysis performed to investigate pulses timings and spectrum, and to disentangle the athermal component of the pulses from the thermal one. Furthermore, we will show the application to our dataset of an alternative method of pulse processing, based upon Principal Component Analysis (PCA). This kind of analysis allow us to recover better energy spectra than achievable with traditional methods, improving the evaluation of the detector threshold energy, a fundamental parameter characterizing the CryoAC particle rejection efficiency.
Free-standing tubular DEAs for multi-directional bending

Highly anisotropic, fiber-based structures are a successful concept in nature. Usual dielectric elastomer actuators are entirely soft and rely on the integration of stiff carrier frames for the fragile dielectric membranes. Within this work, a completely soft, fiber-reinforced free-standing tubular actuator concept is presented. The circumferentially running carbon fibers are integrated into the inner electrode of the DEA and stabilize the cross-section, while having negligible impact on the mechanical stiffness in the axial direction. Through the segmentation of the outer electrode of the actuator, active bending in the corresponding directions is achieved. Moreover, if all segments are activated simultaneously, the actuator expands axially. The presented manufacturing approach allows for the adjustment of the dimensions over a wide range of diameters and lengths. Furthermore, the local stiffness of actuators can be tailored by varying the amount of fibers incorporated into the electrode. The electroactive deformation of actuators with different diameter-to-length ratios and fiber densities is investigated.
Antibiotic consumption history of patients in a referred laboratory in Yaounde

Background Regulation of antibiotic prescription and consumption remains a major public health burden in low- and middle- income countries. Objective This study aimed to describe the antibiotic consumption of patients who had a positive antibiotic culture in a reference laboratory. Methods A retrospective descriptive study was conducted among 113 participants with positive antibiograms with a documented history of antibiotics intake at the Yaoundé University Teaching Hospital in Cameroon between January 2016 and June 2021. Data were stored and analyzed using the Census and Survey Processing System version 7.3 and Statistical Package for Social Science version 25.0. Descriptive statistics were used to estimate the indicators. Results Of the 113 patients enrolled, 105 had a history of drug use; 56 participants (53.3%) had taken at least 2 antibiotics prior to sampling. Cephalosporins were the most consumed antibiotics (41%), followed by nitroimidazols (28.6%) and penicillins (28.6%). According to the World Health Organization classification, 55 (52.4%) took major priority antibiotics. Conclusion We are on the alert and there is an urgent need to raise awareness among clinicians and patients alike by providing them with good clinical practice guidelines.
Masters of media: A longitudinal study of parental media efficacy, media monitoring, and child problematic media use across early childhood in the United States

ABSTRACT The development of problematic media use in early childhood is not well understood. The current study examined long-term associations between parental media efficacy, parental media monitoring, and problematic media use across a three-year period of time during early childhood. Participants included 432 parents who reported on their own parenting and their child’s use of problematic media once a year for three years (M age of child at Wave 1 = 29.68 months, SD = 3.73 months). Results revealed that early parental media efficacy predicted lower levels of child problematic media use over time. Restrictive media monitoring was also related to lower levels of child problematic media use over time. Additionally, general parental efficacy was related to parental media efficacy and lower child problematic media use, both at the cross-sectional and longitudinal levels. Discussion focuses on encouraging early parental media efficacy (and exploring other potential mechanisms) as a way to mitigate the development of problematic media use over time. IMPACT SUMMARY Prior State of Knowledge Though much research has examined the precursors to problematic media use in adolescence or adulthood (e.g., Internet Gaming Disorder), little research has examined predictors of problematic use of media (including the role of parental media efficacy) during early childhood. Novel Contributions Parental media efficacy predicts lower levels of problematic media use across early childhood Practical Implications Parental media efficacy might be one tool to reduce early problematic media use. Educators and health professionals may consider ways to empower parents around media (perhaps through training, messaging, or providing resources and help where needed).
A priori estimates of the principal curvatures of spacelike hypersurfaces in de Sitter space with applications to hypersurfaces in hyperbolic space

Introduction. In the last two decades there has been a substantial interest in studying spacelike hypersurfaces with constant mean curvature in Lorentz-Minkowski space R In +1 and in de Sitter space Sin +1, n -2. This interest is motivated by certain needs in general relativity [CFM], [G], [St], and also by the fact that complete maximal and constant mean curvature hypersurfaces in these spaces exhibit the "Bernstein-type" property, that is, they are of a very special type; for example linear subspaces, totally umbilic, or totally geodesic; [Ca], [CY], [G], [R], [A], [M]. It is a natural and interesting problem to investigate stability of a Bernstein-type property relative to perturbation of the data. One of the main purposes of this paper is to give estimates of the spread of the principal curvatures on a compact spacelike hypersurface in SIn+l in terms of the mean curvature and its derivatives (up to second order). Using these estimates we show that if the mean curvature H on a complete spacelike hypersurface F in SIn+ I is such that H2 < 4 (n 1)/n2 and H is close to a constant (in C2-norm) then F is close to being umbilic. A simple consequence of our estimates is the result of Akutagawa [A] and Montiel [M] showing that complete spacelike hypersurfaces in SI"' with constant mean curvature H such that H2 < 4 (n 1)/n2 are umbilic. Another aim of this paper is to study duality relations between hypersurfaces in hyperbolic space Hn+l and spacelike hypersurfaces in SIn+l. Apart from the well known fact that the Gauss image of a hypersurface in Hn+l lies in SIn+1 (when the two spaces are considered as
Robust Estimates of the Total Alkalinity From Satellite Oceanographic Data in the Global Ocean

Total alkalinity (TA) is a key parameter to understand the dynamics of biogeochemical properties in the global ocean and the effects of climate change on ocean acidification, ocean carbon cycle, and carbonate chemistry. To date, global surface ocean distributions of TA were investigated using multiple regional regression approaches which require smoothening techniques due to severe boundary effects in different oceanic regions/basins across latitudes/longitudes. To reduce the uncertainties and produce spatially and temporally consistent TA products, a novel single linear regression (SLR) approach was developed in this study to estimate TA fields in the global surface ocean waters. The SLR formulation was derived using the continuous in-situ measurements of sea surface salinity (SSS) collected from the different oceans. The performance of the SLR was assessed using independent in-situ/satellite derived TA data and the results from three existing algorithms. In general, the SLR-based global surface ocean TA fields from both in-situ and satellite data agreed well with in-situ measured TA data with a mean relative error less than 1%, which is much lower compared to the error with the existing algorithms. Studies were also conducted to examine the spatiotemporal variability and trends in the global surface ocean climatology of SSS and TA fields in the context of current climate change impacts.
A Canonical Set For Matrices Over a Principal Ideal Ring Modulo m

If m ∈ P where P is a p.i. r. (principal ideal ring), then P/ {m} is a commutative ring with unit element. The elements of this ring are designated by ā where a ∈ P. The set of square matrices of order n with elements in P/ {m} forms a ring with unit element. The units in this ring are the unimodular matrices, i.e., the matrices whose determinants are units of P/ {m}.
Characterisation and Recovery of Minerals in Silages of Sorghum IPA 2502 Irigated with Different Leaching Fractions of Brackish Water

The objective of this study was to evaluate the characteristics and recovery of minerals in silages of sorghum cv. IPA 2502 irrigated with different leaching fractions of brackish water. Sorghum cultivation was carried out in the field in a randomised block design, with four replications and four irrigation leaching fractions (0%, 5%, 10%, and 15%). From the harvested plant material, five silos per treatment, with five repetitions, were arranged in a completely randomised design for ensiling. Leaching fractions did not alter the levels of nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur in sorghum. The sodium content showed a quadratic response to the leaching fractions, which was also observed for iron, manganese, and chloride. In silage, an increasing linear effect was found for nitrogen, whereas for phosphorus, potassium, and sulfur, the contents were reduced with the addition of the leaching fraction. The contents of copper, iron, zinc, and chloride in silages responded in a quadratic way. The use of brackish water, especially the 15% leaching fraction, in the cultivation of sorghum enhances the mineral contents and the recovery of some macro- and micro-nutrients after the ensiling process.
A parallel adaptive numerical method with generalized curvilinear coordinate transformation for compressible Navier–Stokes equations

A fourth‐order finite‐volume method for solving the Navier–Stokes equations on a mapped grid with adaptive mesh refinement is proposed, implemented, and demonstrated for the prediction of unsteady compressible viscous flows. The method employs fourth‐order quadrature rules for evaluating face‐averaged fluxes. Our approach is freestream preserving, guaranteed by the way of computing the averages of the metric terms on the faces of cells. The standard Runge–Kutta marching method is used for time discretization. Solutions of a smooth flow are obtained in order to verify that the method is formally fourth‐order accurate when applying the nonlinear viscous operators on mapped grids. Solutions of a shock tube problem are obtained to demonstrate the effectiveness of adaptive mesh refinement in resolving discontinuities. A Mach reflection problem is solved to demonstrate the mapped algorithm on a non‐rectangular physical domain. The simulation is compared against experimental results. Future work will consider mapped multiblock grids for practical engineering geometries. Copyright © 2016 John Wiley & Sons, Ltd.
Point-Finite And Locally Finite Coverings

1. Introduction. An interesting feature of recent topological developments is the increasingly important role played by locally finite coverings. Point-finite coverings, on the other hand, even though conceptually simpler, have received very little attention. And deservedly so, since they are much less useful. Nevertheless, it sometimes happens (as it did to the author in (5)) that one is confronted by a covering which is known to be point-finite, but not necessarily locally finite.
Family Physician’s Opinions and Recommendations on the Family Medicine Practices

Objectives: This study aims to evaluate the opinions and recommendations of family physicians working in family health centers regarding the practices of family medicine. Methods: This descriptive research was conducted with 307 family physicians working in family health centers of Elazığ and Muş provinces located in the east of Turkey between September and November 2021. The sample of this study was comprised of 193 (62.9%) family physicians who were available during the
