Background
Lasers of different wavelengths have been developed for use in permanent hair reduction. An increase in the manufacturing of home-use laser hair removal devices allows for these treatments to be performed in the comfort of your own home at an affordable cost.

Objective
To evaluate the effectiveness of permanent hair reduction using a Diode laser in comparison to the Silk’n™ Flash and Go Lux (475–1200 nm) home-use laser.

Methods
Fifteen females received six axillae laser hair removal treatments at two to four-week intervals using either a professional laser or home-use laser device. Photographs and hair counts were taken before each treatment and at a three week follow up. A T–test was used to evaluate statistical significance, and regression analysis to determine a difference in the effects. Pain scores and side effects were recorded by a visual analogue scale in a satisfaction questionnaire.

Results
The professional laser showed an overall hair reduction of 85% on the right axilla and 88% on the left axilla. The home-use laser showed an overall reduction of 52% on the right axilla and 46,3% on the left axilla. Mild side effects were experienced for both laser devices. There were no serious adverse effects reported, safety features are effective to a certain extent.

Conclusion
The Flash & Go Lux home-use laser can effectively reduce hair at a slower rate than the Diode laser. The home-use laser device offers protection against accidental exposure to light and use on darker skin types. Risks of retinal damage due to long-term exposure to home-use laser light are still cause for concern.

Abstract
Trisomy 13 is a rare chromosomal disorder in which all or a percentage (mosaicism) of cells contain an extra 13th chromosome. Sinus of Valsalva aneurysms are rare, with an incidence of 0.1% to 3.5% of all congenital heart defects. This article reports the case of a patient with trisomy 13 with a new systolic murmur found to have a ruptured sinus of Valsalva aneurysm diagnosed on coronary computed tomography angiography. This is the first case to report sinus of Valsalva aneurysm rupture secondary to Streptococcus viridans endocarditis in a patient with trisomy 13 syndrome and highlights the importance of coronary computed tomography angiography in noninvasive imaging and surgical planning.

Abstract
The rapid development of technology allows people to obtain a large amount of data, which contains important information and various noises. How to obtain useful knowledge from data is the most important thing at this stage of machine learning (ML). The problem of unbalanced classification is currently an important topic in the field of data mining and ML. At present, this problem has attracted more and more attention and is a relatively new challenge for academia and industry. The problem of unbalanced classification involves classifying data when there is insufficient data or severe category distribution deviations. Due to the inherent complexity of unbalanced data sets, more new algorithms and tools are needed to effectively convert a large amount of raw data into useful information and knowledge. Unbalanced data set is a special case of classification problem, in which the distribution between classes is uneven, and it is difficult to classify data accurately. This article mainly introduces the research on the processing method of computer algorithms based on the processing method of unbalanced data sets based on ML, aiming to provide some ideas and directions for the processing of computer algorithms based on unbalanced data sets based on ML. This article proposes a research strategy for processing unbalanced data sets based on ML, including data preprocessing, decision tree data classification algorithm, and C4.5 algorithm, which are used to conduct research experiments on processing methods for unbalanced data sets based on ML. The experimental results in this article show that the accuracy rate of the decision tree C4.5 algorithm based on ML is 94.80%, which can be better used for processing unbalanced data sets based on ML.

Abstract
A novel strip line fed, circularly polarized (CP), annular slotted dual band antenna using hybrid electromagnetic band gap (EBG) structure for Global Positioning System (GPS) has been herein designed, analyzed, and investigated for wearable applications. Adjusting the radii of the annular slots on the radiating patch excellent circular polarized (CP) radiation and impedance matching is achieved. The design demonstrates Kapton based flexible, robust, and low-profile solution with permittivity of 3.4 to meet the requirements of wearable applications. Due to the high losses of the animal body, the electromagnetic band gap (EBG) structure is used to reduce back radiation and the effect of frequency detuning. The proposed antenna structure also enhances the front-to-back ratio (FBR) by 10 dB. This antenna with dimensions 0.56λ

Authors: Hrubec Marek 
Published: May 2023

Abstract
The article deals with the theme of updating of Cuba’s economic model mainly from the perspective of economic and political philosophy and its interdisciplinary contexts. First, it examines the historical origins of Cuba’s socialist model and the subsequent changes after the fall of the Eastern Bloc. Second, it analyses the actualization of Cuba’s model in the first two decades of the 21st century, that is, mainly the introduction of market and private ownership to complement planning and public ownership. Third, it explains the codification of these changes in the new constitution. Forth and finally, it focuses on an interpretation of international cooperation both in Latin America, especially within the framework of the two pink tides, and with other partners in global interactions, particularly China. This will make it possible to understand the updated Cuba’s model, which the author has coined strategic socialism with Cuban characteristics.
Numerical study on the effect of distortion of S-duct on flow field and performance of a full annulus transonic fan

Published: May 2023

Abstract
To reveal the influence of distortion of S-duct on the flow field and performance of transonic fan, full annulus unsteady numerical simulation was carried out under S-duct/fan integrated condition. This study focuses on the coupling flow of S-duct/fan integrated condition under peak efficiency (PE) condition and near stall (NS) condition. Results show that, compared with the condition that S-duct or fan is investigated alone, the distortion of S-duct is suppressed under S-duct/fan integrated condition. The curved structure of S-duct is the important reason for the flow migration from undistorted region to distortion region. Higher inlet relative Mach number and more work input of the rotor are observed in the counter-swirl region. The flow separation in S-duct is weakened under NS condition compared with that of PE condition. Counter-swirl region of blade tip has larger region of blockage, and rotating stall inception is most likely to occur in this region.

AbstractFluorinated chalcones are organic compounds with diverse biological activities and are of interest for drug development due to their improved properties, such as lipophilicity, bioavailability, and metabolic stability. Therefore, the correlation between structure and properties is fundamental to discover the potential use on pharmaceutical and technological applications. In this sense, we synthesized and characterized a novel fluorinated chalcone (E)-1-(4-fluorophenyl)-3-(naphthalen-1-yl)prop-2-en-1-one (FCH), and compared its supramolecular arrangement and topological analysis with a chalcone (E)-1-(4-hydroxyphenyl)-3-(naphthalen-1-yl)prop-2-en-1-one (HCH). The molecular electrostatic potential, QTAIM, and frontier molecular orbitals of both chalcones were investigated using the M06-2X/6-311++G(d,p) level of theory. Our findings show that the FCH exhibits a herringbone packing with intermolecular interactions of C–H⋯F and C–H⋯π, while the HCH assumes a staircase packing coordinated by O–H⋯O and π⋯π intermolecular interactions. Furthermore, the electrostatic potential analysis shows that FCH is susceptible to electrophilic attack, while HCH is susceptible to nucleophilic attack. Finally, the structural basis analysis for both chalcones indicated that FCH has a higher lipophilicity than HCH due to the stronger hydrogen bond of HCH with water.

Abstract
In several nations, interlocking concrete block pavement (ICBP) is one of the paving technologies employed. Flexible pavement is a widely used pavement type that is prevalent in most countries. The current work aims to evaluate the structural and functional performance of the existing ICBP and flexible pavement, which are laid continuously for similar traffic conditions and age. The study road is a section of a national highway with heavy and frequent traffic. The structural performance was determined using a Geogauge, light weight deflectometer, and Benkelman beam deflectometer. The functional condition assessment comprised roughness and distress study using smartphone sensors after validation with a Roughometer III and a video processing technique. The skid resistance was evaluated using the British pendulum test. Further, a cost analysis was carried out to compare the construction cost for both pavement types. The test results revealed that both types of pavement displayed distinct performances for several structural and functional aspects. It was also concluded that the construction cost of the ICBP was less than the flexible pavement section. The present study aids in understanding the structural and functional performance level of ICBP over flexible pavement.

Authors: Save Sneha L. , Jadhav Priyanka 
Published: May 2023

Background: The lacrimal system includes the tear film of the eye and the tear drainage system. Endoscopic dacryocystorhinostomy (DCR) is a safe and effective method of surgical treatment of nasolacrimal duct obstruction. The anatomy of the nasal cavity is better visualized endoscopically and sac is approached under vision and hence the results are decided at the time of surgery.
Methods: Present clinical study was conducted in tertiary medical centre from July 2015 to July 2016. Total 50 patients with epiphora as evidenced by nasolacrimal duct blockage on sac syringing were included in the study. Children less than 10 years and revision cases were excluded. These patients underwent DCR without stenting.
Results: Out of the 50 patients, 60% were males and 40% were females. Surgical success was deﬁned as anatomical patency and symptomatic relief at the end of the follow up period which was observed in 45 of 50 (90%) patients. Incidence of complications was as low as only 5 patients. These patients were followed up for 6 months with no complaints of epiphora.
Conclusions: Endoscopic DCR is a safe and effective method of surgical treatment of nasolacrimal duct obstruction. It gives equivalent symptomatic relief from epiphora when compared to external method. Thus, we can minimize complications, discomfort, cost of stenting and follow up visits after endonasal surgery. Due to higher success rate, minimal invasiveness and high patient satisfaction as compared to other procedures, it has gained more popularity.

To study the incidence of cerebral visual impairment among children with history of perinatal neurological insult and congenital brain anomalies and to analyze the outcome following visual intervention programme. A prospective interventional study, examining 100 children less than 7 years over a period of 1 year. All children with history of perinatal hypoxia, neonatal hypoglycemia, neonatal seizures, infantile spasm, epilepsy, congenital hydrocephalus, congenital brain anomalies, CNS infections, traumatic brain injury and post cardiac surgery, excluding children with ocular visual impairment. Of the 100 children studied, the incidence of CVI was 87%. The associated ocular problems were found to be low visual acuity seen in 85%, strabismus in 25%, refractive error in 39%, Nystagmus in 21% and oculomotor apraxia in 6%. The most common etiology was hypoxic ischemic encephalopathy, contributing to 30% of the cases and most common MRI findings were periventricular leukomalacia, seen in 42%. CVI Range was used for functional visual assessment. Visual intervention rather than visual stimulation was taught to the primary care giver and children were followed up every 3 months. 26% of children had improved in their functional vision after 6 months of Individualized intervention. Early identification and individualized visual intervention, integrating them into many activities of the child across the whole day, form a crucial part of the visual outcome. Improvement in vision creates access to a world of cognitive and motor development.

La fragmentación de lo público en la ciudad: organización socioespacial, marco institucional y sociabilidad urbana
Authors: Rodríguez Cortés Luisa 
Published: May 2023

La configuración de las ciudades ha impactado invariablemente en la producción del ámbito público, tanto en su acepción institucional donde el eje central lo constituye el Estado, como en sus dimensiones relacional y espacial. Ante este escenario, es pertinente preguntarse cómo se configura la dimensión pública en el marco de las ciudades actuales. El presente artículo se propone contribuir a responder esta pregunta a partir de examinar tres dimensiones que son fundamentales en la dimensión pública en la ciudad: la organización socioespacial; el marco institucional y la sociabilidad urbana.Para esto, se realiza una revisión de carácter teórico, teniendo como referencia el caso de la Ciudad de México, con el objetivo de dar luz sobre los procesos que marcan los límites y contenidos de lo que definimos como público. Como conclusión se argumenta que la dimensión pública en la ciudad se encuentra altamente fragmentada, producto de la forma como se estructura el orden urbano, las acciones focalizadas y desvinculadas de los gobiernos y los limitantes y dificultades para el encuentro y diálogo entre diferentes.
