Implant Placement Using Ridge-split Procedure with Piezosurgery in Mandibular Anterior Region: A Case Report

The enhancement of ridge-split procedure by piezosurgery provides adequate buccolingual width for implant placement in atrophied alveolar ridges. A 50-year-old systemically healthy female reported with 3 mm of buccolingual width in the anterior mandibular alveolar ridge. The patient underwent immediate implant placement after alveolar ridge split done by piezosurgery and the use of expanders. Functional prosthetic rehabilitation was done after 3 months. The ridge-split procedure has predictable results in implant survival. The piezosurgical unit provides more favorable osseous results than hand instruments.
Underestimation of probability modifications: characterization and economic implications

The aim of this paper is to propose a behavioral characterization of individuals who underestimate probability modifications and to characterize this behavior in the standard preferences representation models under risk (Expected utility, Dual theory, Rank Dependant Utility Theory and MaxMin Expected Utility). Our main results are the following. Underreaction to probability modifications is in general independent from standard risk aversion and prudence. In models involving probability transformation functions, it is characterized by the slope of the probability transformation function. In the MaxMin Expected utility model under risk, it is related to the weights of the maximal and minimal consequences in the preferences representation function. Considering a simple prevention decision, consisting in the reduction of the probability of a monetary loss, we show that individuals who underreact to probability modifications invest less in prevention than individuals who objectively evaluate these modifications. Underreaction to probability modification is thus a possible explanation for low investment in prevention. (This abstract was borrowed from another version of this item.)
An Effective Noise Reduction Algorithm in Signal Edge Detection

Noise as an unwanted factor always degrades the edge detection performance. Exploiting real edges under noise contaminated condition has been a challenge in the edge detection issue, especially when the noise power is high. This paper presents a robust edge detection method in a noisy condition based on the 1D wavelet transform domain as a solution for the noise problem. First of all, a new group of wavelet basis functions for the edge detection is introduced. Then, a basic ramp function is modeled by a Gaussian approximation, and edge detection according to introduced bases derived from relevant formulas is discussed. We develop the multiscale production method and present a new algorithm to reinforce real peaks and suppress fake edges. Finally, the simulation results of the edge detecting for the noisy uniform step edge are provided to evaluate proposed algorithm efficiency. The results showed that our scheme is more effective than the production of adjacent coefficients method in the low signal to noise ratio condition.
Wind Estimation in the Lower Atmosphere Using Multirotor Aircraft

AbstractUnmanned aerial vehicles are increasingly used to study atmospheric structure and dynamics. While much emphasis has been on the development of fixed-wing unmanned aircraft for atmospheric investigations, the use of multirotor aircraft is relatively unexplored, especially for capturing atmospheric winds. The purpose of this article is to demonstrate the efficacy of estimating wind speed and direction with 1) a direct approach using a sonic anemometer mounted on top of a hexacopter and 2) an indirect approach using attitude data from a quadcopter. The data are collected by the multirotor aircraft hovering 10 m above ground adjacent to one or more sonic anemometers. Wind speed and direction show good agreement with sonic anemometer measurements in the initial experiments. Typical errors in wind speed and direction are smaller than 0.5 and 30°, respectively. Multirotor aircraft provide a promising alternative to traditional platforms for vertical profiling in the atmospheric boundary layer, especially.
Potential application of PS-OCT in the safety assessment of non-steroidal topical creams for atopic dermatitis treatment

Crisaborole 2% ointment is a non-steroidal treatment for mild-moderate atopic dermatitis (AD) and may produce fewer adverse effects than topical corticosteroids (TCS). We used PS-OCT to quantify dermal collagen at baseline and after 29 days of treatment with crisaborole and betamethasone valerate (BMV), in 32 subjects. PS-OCT detected a mean increase 1 × 10-6, 95% CI (6.3, 1.37) × 10-6 in dermal birefringence following TCS use (p < 0.0001, ad-hoc, not powered), whereas a change of -4 × 10-6, 95% CI (-32, 24) × 10-6 was detected for crisaborole (p = 0.77, ad-hoc, not powered). These results could suggest a differential effect on dermal collagen between the two compounds. PS-OCT may thus find an important role in safety assessment of novel AD treatment’ and larger trials are warranted.
Solving Zero-dimensional Polynomial Systems through the Rational Univariate Representation

This paper is devoted to the {\it resolution} of zero-dimensional systems in $K[X_1,\ldots X_n]$, where $K$ is a field of characteristic zero (or strictly positive under some conditions). We give a new definition for {\rm solving zero-dimensional systems} by introducing the {\it Univariate Representation} of their roots. We show by this way that the solutions of any zero-dimensional system of polynomials can be expressed through a special kind of univariate representation ({\it Rational Univariate Representation}): $$ \begin{array}{c} f(T)=0 \\ X_1=\frac{g_1(T)}{g(T)} \\ \vdots \\ X_n=\frac{g_n(T)}{g(T)} \\ \end{array} $$ where $(f,g,g_1,\ldots ,g_n)$ are polynomials of $K[X_1,\ldots ,X_n]$, without loosing geometrical information (multiplicities, real roots). Moreover we propose different efficient algorithms for the computation of the {\it Rational Univariate Representation}, and we make a comparison with standard known tools.

The numerical solution for the time fractional advection‐diffusion problem in one‐dimension with the initial‐boundary condition is proposed in this paper by B‐spline finite volume element method. The fractional derivative is Caputo in the proposed scheme. The stability of the proposed numerical method is studied, and the numerical results presented support the theoretical results.
Solicitation and Sexualized Interactions of Minors with Adults: Prevalence, Overlap with Other Forms of Cybervictimization, and Relationship with Quality of Life

ABSTRACT Sexual solicitation and sexualized interaction with minors by adults constitute one of the most pernicious risks of the Internet. Little is known about the age range in which this phenomenon is most prevalent or the relationship and overlap of this problem with other risks, such as peer-to-peer cybervictimization and cyber dating abuse. Additionally, little empirical evidence exists on whether the overlap between these types of online victimization affects health-related quality of life (HRQoL). This study aimed to: 1) analyze the prevalence of sexual solicitation and interaction according to sex and stage of adolescence; 2) relate this problem to other forms of online victimization (cybervictimization and cyber dating abuse); 3) analyze the overlap between these forms of online victimization and differences in HRQoL scores. A cross-sectional and analytical study with 3,578 adolescents (52.7% girls) aged between 10-15 years was carried out. Of the adolescents in the study sample, 12.6% (n = 448) had received sexual requests and 6.4% (n = 230) had interacted sexually with adults. Sexual solicitation was most common among girls in middle adolescence. Of the participants, 33.9% (n = 1,216) had been involved in some form of online victimization. Peer cybervictimization and cyber dating abuse were positively and significantly correlated with sexualized solicitation/interactions with adults. Victims with the overlapping of all three types of online victimization (2.7%, n = 98) presented the lowest HQRoL scores (p < .001).
Joint Learning of Semantic Segmentation and Height Estimation for Remote Sensing Image Leveraging Contrastive Learning

Semantic segmentation (SS) and height estimation (HE) are two critical tasks in remote sensing scene understanding that are highly correlated with each other. To address both the tasks simultaneously, it is natural to consider designing a unified deep learning model that aims to improve performance by jointly learning complementary information among the associated tasks. In this article, we learn the two tasks jointly under a deep multitask learning (MTL) framework and propose two novel objective functions, called cross-task contrastive (CTC) loss and cross-pixel contrastive (CPC) loss, respectively, to enhance MTL performance through contrastive learning. Specifically, the CTC loss is designed to maximize the mutual information of different task features and enforce the model to learn the consistency between SS and height estimation. In addition, our method goes beyond previous approaches that only apply contrastive learning at the instance level. Instead, we design a pixelwise contrastive loss function that pulls together pixel embeddings belonging to the same semantic class, while pushing apart pixel embeddings from different semantic classes. Furthermore, we find that this semantic-guided contrastive loss simultaneously improves the performance of the HE task. Our proposed approach is simple and effective and does not introduce any additional overhead to the model during the testing phase. We extensively evaluate our method on the Vaihingen and Potsdam datasets, and the experimental results demonstrate that our approach significantly outperforms the state-of-the-art methods in both HE and SS.
Impact of Long-Term Observation on the Sampling Characteristics of TRMM PR Precipitation

AbstractObservations of the Tropical Rainfall Measuring Mission Precipitation Radar (TRMM PR) over 16 yr yielded hundreds of large precipitation systems (≥100 km) for each 0.1° grid over major rainy regions. More than 90% of the rainfall was attributed to large systems over certain midlatitude regions such as La Plata basin and the East China Sea. The accumulation of high-impact snapshots reduced the significant spatial fluctuation of the rain fraction arising from large systems and allowed the obtaining of sharp images of the geographic rainfall pattern. Widespread systems were undetected over low-rainfall areas such as regions off Peru. Conversely, infrequent large systems brought a significant percentage of rainfall over semiarid tropics such as the Sahel. This demonstrated an increased need for regional sampling of extreme phenomena. Differences in data collected over a period of 16 yr were used to examine sampling adequacy. The results indicated that more than 10% of the 0.1°-scale sampling error acc.
Low‐profile omnidirectional circularly polarized antenna based on substrate integrated waveguide technology

A substrate integrated waveguide (SIW) circularly polarized (CP) antenna with omnidirectional radiation in the azimuthal plane is proposed. The antenna consists of five identical end‐fire CP antenna elements in a pentagonal array configuration, which is loaded on a circular substrate. Each element contains an H‐plane horn antenna in SIW structure and a printed dipole antenna. Five parasitic curve elements are introduced to improve the omnidirectional property of the antenna. Combined with complementary dipoles theory and SIW technology, prototype antenna is designed, fabricated and measured. With a low profile of 0. 024λ0, the antenna has a 10‐dB return‐loss impedance bandwidth of 4.08% (2.4∼2.5 GHz) and a 3‐dB axial‐ratio (AR) bandwidth of 5.76% (2.36∼2.50 GHz). The antenna works well in the 2.45 GHz ISM band, with good cross‐polarization and excellent omnidirectional property.
Genetic Screening of a Hungarian Cohort with Focal Dystonia Identified Several Novel Putative Pathogenic Gene Variants

Dystonia is a rare movement disorder which is characterized by sustained or intermittent muscle contractions causing abnormal and often repetitive movements, postures, or both. The two most common forms of adult-onset focal dystonia are cervical dystonia (CD) and benign essential blepharospasm (BSP). A total of 121 patients (CD, 74; BSP, 47) were included in the study. The average age of the patients was 64 years. For the next-generation sequencing (NGS) approach, 30 genes were selected on the basis of a thorough search of the scientific literature. Assessment of 30 CD- and BSP-associated genes from 121 patients revealed a total of 209 different heterozygous variants in 24 genes. Established clinical and genetic validity was determined for nine heterozygous variations (three likely pathogenic and six variants of uncertain significance). Detailed genetic examination is an important part of the work-up for focal dystonia forms. To our knowledge, our investigation is the first such study to be carried out in the Middle-European region.
Endothelial cell function : new considerations

The endothelium governs a broad range of critical vascular functions and adapts to local requirements in a rapid temporal fashion. Dysfunction of the endothelium can be considered to be present when its properties, either in the basal or stimulated state, are recast in a fashion inappropriate to the preservation of organ function. When the endothelium is operationally intact and its various functions are summed, the overall effects realized include physiologically appropriate vasodilation as well as the effective dampening of proinflammatory and procoagulant processes. Newly available technologies now allow endothelial function to be studied in a considerably more longitudinal fashion than what had been previously possible. As a result, endothelial function is now being studied under diverse pathophysiological settings. For example, preliminary findings suggest that endothelial function exhibits a diurnal pattern with a nadir in function occurring in the early morning hours. Furthermore, it is now recognized that postprandial triglyceride-rich lipoproteins cause endothelial dysfunction in both the coronary and brachial arteries, a phenomenon which remits when ACE inhibitors and possibly angiotensin receptor antagonists are given. Recently, it has been observed that endothelial function is impaired both in patients with chronically elevated homocysteine levels and in those experiencing an acute elevation in homocysteine, as occurs following administration of oral methionine. Homocysteine effect is inhibited by pre-treatment with Vitamins C or E. As this review has demonstrated, the number of variables and treatment considerations relative to endothelial dysfunction are proliferating in a geometric fashion. The area of endothelial dysfunction will be one of intensive study in the coming decade.
Conformal Field Theory and Functions of Hypergeometric Type

Conformal field theory provides a universal description of various phenomena in natural sciences. Its development, swift and successful, belongs to the major highlights of theoretical physics of the late XX century. In contrast, advances of the theory of hypergeometric functions always assumed a slower pace throughout the centuries of its existence. Functional identities studied by this mathematical discipline are fascinating both in their complexity and beauty. This thesis investigates the interrelation of two subjects through a direct analysis of three CFT problems: two-point functions of the 2d strange metal CFT, threepoint functions of primaries of the non-rational Toda CFT and kinematical parts of Mellin amplitudes for scalar four-point functions in general dimensions. We flash out various generalizations of hypergeometric functions as a natural mathematical language for two of these problems. Several new methods inspired by extensions of classical results on hypergeometric functions, are presented. This work is based on our publications [1–3] as well as on one paper at the final stage of preparation [4]. This thesis is based on following publications: • M. Isachenkov, I. Kirsch and V. Schomerus, Chiral Primaries in Strange Metals, Nucl. Phys. B 885, 679 (2014) [arXiv:1403.6857 [hep-th]]. • M. Isachenkov, I. Kirsch and V.

High-resolution image reconstruction: An envℓ1 /TV model and a fixed-point proximity algorithm

High-resolution image reconstruction obtains one high-resolution image from multiple lowresolution, shifted, degraded samples of a true scene. This is a typical ill-posed problem and optimization models such as the l2/TV model are previously studied for solving this problem. It is based on the assumption that during acquisition digital images are polluted by Gaussian noise. In this work, we propose a new optimization model arising from the statistical assumption for mixed Gaussian and impulse noises, which leads us to choose the Moreau envelop of the l1-norm as the fidelity term. The developed envl1/TV model is effective to suppress mixed noises, combining the advantages of the l1/TV and the l2/TV models. Furthermore, a fixed-point proximity algorithm is developed for solving the proposed optimization model and convergence analysis is provided. An adaptive parameter choice strategy for the developed algorithm is also proposed for fast convergence. The experimental results confirm the superiority of the proposed model compared to the previous l2/TV model besides the robustness and effectiveness of the derived algorithm.
Second order sliding mode and adaptive observer for synchronization of a chaotic system: a comparative study

In this paper two nonlinear observers for a chaotic system are compared. Moreover, the left invertible problem and the observability singularity are discussed. Thus, after a presentation of both observers, a comparison of the two proposed methods and a discussion are done on the basis of simulations results. The last part highlights the fact that the finite time observer is more sensible to the singularity observations, but less sensible to parameter uncertainties and noise in the output of the system.
Beneficial Bacteria Isolated from Food in Relation to the Next Generation of Probiotics

Recently, probiotics are increasingly being used for human health. So far, only lactic acid bacteria isolated from the human gastrointestinal tract were recommended for human use as probiotics. However, more authors suggest that probiotics can be also isolated from unconventional sources, such as fermented food products of animal and plant origin. Traditional fermented products are a rich source of microorganisms, some of which may have probiotic properties. A novel category of recently isolated microorganisms with great potential of health benefits are next-generation probiotics (NGPs). In this review, general information of some “beneficial microbes”, including NGPs and acetic acid bacteria, were presented as well as essential mechanisms and microbe host interactions. Many reports showed that NGP selected strains and probiotics from unconventional sources exhibit positive properties when it comes to human health (i.e., they have a positive effect on metabolic, human gastrointestinal, neurological, cardiovascular, and immune system diseases). Here we also briefly present the current regulatory framework and requirements that should be followed to introduce new microorganisms for human use. The term “probiotic” as used herein is not limited to conventional probiotics. Innovation will undoubtedly result in the isolation of potential probiotics from new sources with fascinating new health advantages and hitherto unforeseen functionalities.
Comparison of 7-Year, Real-World Clinical Outcomes between Drug-Coated Balloon Angioplasty versus Drug-Eluting Stent Implantation in Patients with Drug-Eluting Stent In-Stent Restenosis

There are no data available comparing the real-world, long-term clinical outcomes of drug-eluting balloon (DEB) angioplasty and drug-eluting stent (DES) implantation in DES in-stent restenosis (ISR) lesions. We aimed to compare the real-world, long-term data available between DEBs and DESs in DES-ISR lesions. We analyzed consecutive DES-ISR lesions (225 lesions from 205 patients; male: 66.3%; mean age: 62.4 years) treated with either DEB or DES. The primary endpoint was target lesion revascularization (TLR), and the primary safety endpoint was the lesion-oriented composite outcome (LOCO). The LOCO is composed of cardiac death, myocardial infarction, and target lesion thrombosis during follow-up. During the 7-year follow-up period, TLR did not differ significantly between the DEB (n = 108) and the DES groups (n = 117) (HR: 1.07; 95% CI: 0.59–1.93, p = 0.83). The LOCO was significantly lower in the DEB group compared to the DES group (HR: 0.40; 95% CI: 0.16–0.98, p = 0.04), which was mainly driven by the lower levels of myocardial infarction (HR: 0.24; 95% CI: 0.06–0.94, p = 0.04) and the absence of target lesion thrombosis in the DEB group (vs. DES group 6%, p = 0.02). Additionally, cardiac death was found to be similar between the DEB and DES groups (HR: 0.56; 95% CI: 0.18–1.75, p = 0.32). DEB angioplasty showed favorable safety with a similar efficacy to that of DES implantation in DES-ISR lesions during the long-term follow-up period.
