Tongue-tie division. Is it worth it? A retrospective cohort study

Background: Breastfeeding is a complex process, influenced by various factors. Tongue tie may be an impediment to breastfeeding, so division of tongue tie (frenotomy) is routinely recommended to improve breastfeeding. Aims: This study aimed to assess the value of frenotomy based on its impact on breastfeeding-related problems. Methods: A 1-year retrospective cohort study was undertaken of all the patients referred to a London-based tongue-tie service with breastfeeding difficulties. A telephone survey was performed using a standardised questionnaire. Findings: The rate of exclusively breastfed babies increased from 36.7% before frenotomy to 53.8% at 48 hours post-procedure. All the breastfeeding-related problems significantly reduced by 48 hours post-procedure. There was no major bleeding, infection or ulceration reported. Of babies that had frenotomy, 3.2% underwent a second procedure. Conclusions: Frenotomy is a well-tolerated surgical procedure accompanied by very low complication rates. It significant.
The Dorsal Column Nuclei Neuroanatomy Reveals A Complex Sensorimotor Integration and Distribution Hub

The dorsal column nuclei (DCN) are organised by both somatotopy and modality, and have a diverse range of afferent inputs and projection targets. The functional organisation and connectivity of the DCN implicate them in a variety of sensorimotor functions, beyond their commonly accepted role in processing and transmitting somatosensory information to the thalamus, yet this is largely underappreciated in the literature. In this review, we examine the morphology, organisation, and connectivity of the DCN and their associated nuclei, to improve understanding of their sensorimotor functions. First, we briefly discuss the receptors, afferent fibres, and pathways involved in conveying tactile and proprioceptive information to the DCN. Next, we review the modality and somatotopic arrangements of the constituents of the dorsal column nuclei complex (DCN-complex), which includes the gracile, cuneate, external cuneate, X, and Z nuclei, and Bischoff’s nucleus. Finally, we examine and discuss the functional implications of the myriad of DCN-complex projection targets throughout the midbrain, and hindbrain, in addition to their modulatory inputs from the cortex. The organisation and connectivity of the DCN-complex suggest that these nuclei should be considered a complex integration and distribution hub for sensorimotor information.
An Intrusive PCE Extension of the Contour Integral Method and its Application in Electrical Engineering

For the study of electromagnetic waves in a 2D environment, the Helmholtz equation can be reformulated in boundary integral form by the so‐called Contour Integral Method (CIM). The influence of uncertainty in the geometry is studied via Polynomial Chaos Expansion (PCE). A distinction is made between the so‐called intrusive and non‐intrusive PCE. Both methods are applied to the CIM and compared to each other and to Monte‐Carlo simulation (MC).
Communication-Aware Energy Efficient Trajectory Planning With Limited Channel Knowledge

Wireless communications is nowadays an important aspect of robotics. There are many applications in which a robot must move to a certain goal point while transmitting information through a wireless channel which depends on the particular trajectory chosen by the robot to reach the goal point. In this context, we develop a method to generate optimum trajectories which allow the robot to reach the goal point using little mechanical energy while transmitting as much data as possible. This is done by optimizing the trajectory (path and velocity profile) so that the robot consumes less energy while also offering good wireless channel conditions. In this article, we consider a realistic wireless channel model as well as a realistic dynamic model for the mobile robot (considered here to be a drone). Simulations results illustrate the merits of the proposed method.
An improved nonlinear proportional-integral-differential controller combined with fractional operator and symbolic adaptation algorithm

Parameter adjustment is usually applied for designing the proportional-integral-differential (PID) controllers. However, the ability to improve control performance by adjusting parameters is limited. Hence, with the goal to achieve ideal closed-loop response, this paper takes advantage of a structural optimization method for modifying the controller model. A symbolic adaptation algorithm for fractional order PID (FOPID) controller is employed to obtain precise nonlinear controller model. Firstly, a modeling comparison for nonlinear duffing system is carried out to highlight the efficiency of the symbolic adaptation algorithm. The case study indicates the proposed algorithm can establish compact dynamic models by amending the shortcomings of symbolic regression. Secondly, the proposed controller is restructured with the linear FOPID controller and its nonlinearity is increased by adjusting controllers’ components in symbolic form. The proposed controllers are simulated in an unstable second-order system, a time-delay system and a nonlinear VanderPol system. Compared with the IOPID and the FOPID controller, the symbolic adaptation algorithm improves the structural flexibility of these linear controllers. Meanwhile, the system response can better approximate the desired response and the structural integrity of the nonlinear controller model is guaranteed simultaneously. Finally, the nonlinear FOPD controllers for trajectory tracking experiments are carried out on a rotary inverted pendulum control system.
DC and 28 GHz Reliability of a SOI FET Technology

We introduce experimental results of the I-V degradation characteristics of a Silicon SOI technology for RF applications when stressed under both; a 28 GHz and a DC stress input signals. Then we compare the effect of DC and RF stress on threshold voltage, transconductance, and drain current capability. We observe that reliability under RF stress is gate voltage dependent, and in some cases an improvement (“healing”) of the I-V characteristics is observed. A hypothetical explanation for the degradation/enhancement under RF stress is attributed to a self-heating and self-healing (SH2) mechanism. The degradation mechanism is also simulated, and the reliability model tested, with Cadence.
Cross-Polarization Suppression of a Dual-Polarized Microstrip Antenna Using Enclosed Substrate-Integrated Cavities

An enclosed substrate-integrated cavities (ESICs) backed dual-polarized (DP) array with suppressed cross polarization for an X-band radar is investigated. Initially, stacked patches and cross aperture-coupled technique are utilized to achieve a wideband impedance matching and a DP operation. Additionally, a couple of multistage corporate feed networks based on the pairwise anti-phase feed technique are employed to suppress cross polarization over the operating band. Finally, five ESICs are inserted into the array to further suppress the cross polarization. A prototype of array is fabricated and measured. The measured results show that the DP array yields fractional bandwidths (VSWR ≤ 2) of 29.89% for Port H and 30.73% for Port V. The cross-polarization levels are better than –42 dB for V-pol and –44 dB for H-pol at 9.6 GHz, and the isolation between two ports remains above 39 dB over the whole operating bandwidth.
Serum HBV DNA and ALT Kinetics in The Trials of Antiviral Agents in Patients with Chronic Hepatitis B (Appropriate sampling time for Response Assessment of Antiviral Therapy in Chronic Hepatitis B Patients)

Hepatitis B virus (HBV) infection is a widespread disease that affects about 350 million people worldwide, contributing to global public health problems and 25-40% of these will die from liver cirrhosis or primary hepatocellular carcinoma [1-3]. Therapeutic tools for patients with chronic HB include the nucleoside analogue lamivudine and cytokine interferon α (IFN-α) based on several credible clinical trials [3-5]. In the study by Disenstag et al. [3] and Jonas et al.

A Novel Design of Radiation Pattern-Reconfigurable Antenna System for Millimeter-Wave 5G Applications

In this article, a novel design of dielectric resonator antenna (DRA) with a reconfigurable radiation pattern capability is presented. Reconfigurability in the azimuth plane is achieved by symmetrically placing six electromagnetic bandgap (EBG) sectors around the DRA. Each sector is composed of 26 circular-shaped mushroom-like EBG unit cell. In order to achieve 360° pattern reconfigurability with a minimum number of diodes, a network of metallic veins printed on a conductor-backed dielectric slab is used to group and connect the vias in each EBG sector. In addition, a switching p-i-n diode is integrated to the circuit to control the beam steering in the entire azimuth plane toward the respective desired sector by turning on and off the diode. Sixty GHz DRA prototype incorporating the EBG switching circuit is fabricated and tested. Results show 360° pattern reconfigurability in the azimuth plane, with a realized gain of 4.2 dBi, and less than −16 dB impedance matching level over the desired bandwidth are achieved.

This article presents the design of a microstrip patch antenna at different frequencies above 20 GHz that intended to be used for fifth generation (5G) telecommunication system. The design of microstrip patch antenna that has a radiating element with a rectangular shape and partial ground plane is proposed. The patch antenna is designed using a Rogers RT5880 substrate with dielectric constant, εr of 2.2. The results of the designed antenna design analyzed in terms of the reflection coefficient, bandwidth, gain, and directivity performance. The proposed patch antennas at design frequencies of 25.875 GHz, 38.75 GHz, 43 GHz, 46.25 GHz, 48.7 GHz, 51.5 GHz, 71 GHz, and 83.5 GHz have a fractional bandwidth, gain and directivity that respectively greater than 10.2 %, 2.159 dB and 2.562 dBi. All designs and analysis are performed by using the CST Microwave Studio software.
Average trapping time of weighted scale-free m-triangulation networks

This paper investigates the average trapping time (ATT) on weighted scale-free m-triangulation networks. ATT is the mean of the first-passage time from any node to the trap fixed at a hub node over the entire network. Based on the structural properties of weighted scale-free m-triangulation networks, we deduce the accurate expression of ATT for weight-dependent walk. The result shows that the scaling expression of ATT with network size obeys a power-law function with exponent characterized by the weight factor r and the growth factor m. Further, we find that the parameters r and m have a significant impact on the diffusion efficiency of the network, namely, the smaller r and m are, the more efficient the trapping process of the network is.
On Weak Projectivity in Arithmetic

In the 19th century, non-Euclidean geometries were discovered and studied. In the 20th century, non-Diophantine arithmetics were discovered and studied. Construction of non-Diophantine arithmetics is based on very general mathematical structures, which are called abstract prearithmetics, as well as on the projectivity relation between abstract prearithmetics. In a similar way, as set theory gives a foundation for mathematics, the theory of abstract prearithmetics provides foundations for the theory of the Diophantine and non-Diophantine arithmetics. In this paper, we study relations between operations in abstract prearithmetics exploring how properties of operations in one prearithmetic impact properties of operations in another prearithmetic. In addition, we explore how to build new prearithmetics from existing ones.
Structural inpainting techniques using equations of engineering physics

A comprehensive survey on structure-based inpainting methods based on equations of engineering physics is provided in this work. Diffusion equations, describing the random motion of the micro-particles in physics, have been successfully applied in the image processing areas in the last decades. Nonlinear anisotropic diffusion-based structural inpainting techniques, using variational and non-variational PDE models, are discussed first. Influential variational interpolation approaches, such as those using the Mumford–Shah functional, total variation inpainting and its versions, and Euler’s Elastica inpainting, are addressed here. Second and fourth-order anisotropic diffusion-based interpolation schemes, some of them not following variational principles, are then presented. Our own contributions in this field are also discussed. The applications of the reaction-diffusion equations, like Ginzburg–Landau equation, describing a large variety of physics phenomena, in the inpainting domain, are described next. Structural reconstructions methods using partial differential equations for fluid dynamics, such as the Navier–Stokes equations describing the motion of the viscous fluids, are then considered here. Other state of the art third-order PDE-based structural inpainting algorithms surveyed here are based on the curvature-driven diffusion equations that use the thermal diffusion principle in physics. Fourth-order PDE-based interpolation solutions, such as Cahn–Hilliard inpainting that uses a modified mathematical physics equation describing the phase separation process, are also described.
Observation of phase pattern accelerating zonal flow

We report the first experimental observation of zonal flow (ZF) formation through phase patterning. Here the ‘phase’ refers to the eikonal phase carried by streamer-like mode. It is observed that the phase-gradient profile tends to form ‘shock’ layer structures in regions where there are strong streamer-ZF interactions. The emergence of phase-gradient shock layers invalidate the constant-phase-gradient hypothesis, which is frequently employed in the modulational instability models of ZF generation, and is consistent with a recent theoretical work (Guo et al 2016 Phys. Rev. Lett. 117 125002), which predicts that the phase-curvature (gradient of the phase-gradient) can produce a new Reynolds force and accelerate the ZF. By decomposing the Reynolds’ force of the tilted streamers into a phase curvature driven piece and an amplitude inhomogeneity driven one, it is found that inside the shock layers the phase curvature plays a prominent role in accelerating the ZF. We also explore the formation mechanism of the phase pattern and its consistent dynamics with phase-curvature-driven ZF. These findings potentially open a new way to understand the various elusive self-organization phenomena in plasma turbulence.
Management of class I malocclusion with unilateral first premolar extractions – a case report

Over the past 20 years, there has been an increase in the percentage of non-extraction cases in the average orthodontic practice, which now stands as high as 80%. Mid-arch extractions can compromise facial esthetics, especially in patients with concave profiles. The treatment plan must allow for post-treatment facial growth, including the tendency for the noses and chins of young adults to grow more forward than their lips. Decision of extraction of permanent teeth should be based on sound diagnosis, and it should be evidence based. This is a case report of young male patient who had moderate crowding, anterior crossbites, highly placed canine with midlines shift and an unaesthetic smile. The case was treated with unilateral first premolar extractions by using a simple modification of Nance palatal arch and individual T loop along with pre-adjusted Edgewise appliance.

Vektorske vložitve kemijskih struktur

V raziskavah in iskanju novih zdravil nam danes pomagajo racunalniske tehnologije. Že ustvarjene podatkovne zbirke so na primer lahko uporabljene za klasifikacijo kemijskih struktur. V nalogi nas je zanimala kvaliteta vektorskih vložitev kemijskih struktur z avtokodirnikom pri problemih klasifikacije, kjer bi jih lahko uporabljali kot alternativo že uveljavljenim prstnim odtisom. Arhitektura avtokodirnika sledi trendom raziskav, kjer so uporabljene konvolucijske plasti in rekurencne enote z vrati. Samo kvaliteto vložitev smo ocenjevali na realnih podatkovnih zbirkah aktualnih ucinkovin. Raziskave so pokazale, da so vektorske vložitve primerljive z že razvitimi prstnimi odtisi. Na nekaterih primerih nudi vektorske predstavitve ucinkovin, ki izboljsajo tocnost uporabljenih tehnik strojnega ucenja. Razvili smo tudi gradnik za odprto-kodno programsko opremo Orange, ki omogoca vektorsko vložitev kemijskih struktur v notaciji SMILES tako z metodo razvito v nalogi, kot tudi z ostalimi prstnimi odtisi uporabljenimi v nalogi.
Identiﬁcación Robusta de Sistemas no Lineales mediante Algoritmos Evolutivos

Al proceso de identificacion de los parametros de un modo nominal y su incertidumbre para su utilizacion en Control Robusto se le conoce como Identificacion Robusta Parametrica (IR). Un posible enfoque para abordar la IR, que resulta apropiado cuando el desconocimiento de las propiedades estadisticas del ruido y/o la dinamica no modelada invalidan los enfoques estocasticos, es el deterministico (Set Membership Estimation). Este enfoque asume que el error de identificacion (EI), diferencia entre las salidas medidas de proceso y las simuladas del modelo, aunque es desconocido, esta acotado. De ahi que, bajo este enfoque, se persiga la determinacion del conjunto de parametros que consiguen mantener el El acotado para una determinada norma y cota. Dicho conjunto es conocido como el conjunto de parametros factibles (FPS). Cuando el modelo es lineal respecto de sus parametros, el FPS, si existe, es un politopo convexo. En modelos no lineales dicho politopo puede ser no convexo e incluso inconexo. En esta tesis se presenta una metodologia de IR, que permite determinar FPS, de cualquier tipo, en modelos no lineales cualesquiera, acotando el EI simultaneamente mediante varias normas. La metodologia transforma el problema de IR en un problema de optimizacion multimodal con infinitos optimos globales, los cuales constituyen el FPS. Para su optimizacion se ha desarrollado un algoritmo evolutivo (EA) especifico e-GA, que caracteriza el FPS mediante un conjunto discreto de modelos FPS* adecuadamente distribuido a lo largo del FPS. La metodologia viene acompanada de un procedimiento que facilita la determinacion de las cotas, asociadas a las normas que acotan el EI, para asegurar que FPS no sea un conjunto vacio. Para ello, se utiliza la informacion que genera el frente de Pareto resultante de la minimizacion simultanea de las normas mediante una optimizacion multiobjetivo. Para resolver este problema de optimizacion se ha de
