AbstractNon-syndromic cleft lip with or without cleft palate (NSCL/P) is the most common developmental defect that significantly affects the morphology and function of the stomatognathic system in children. The etiology of these birth defects is multifactorial, and single nucleotide polymorphisms (SNPs) inIRF6andFGF1have been associated with NSCL/P. This study aimed to evaluate whether SNPs inIRF6, namely rs2013162, rs642961, rs2235373, and rs34010 inFGF1, are associated with NSCL/P occurrence in the Polish population. The study included 627 participants: 209 children with NSCL/P and 418 healthy controls. DNA was isolated from saliva in the study group and from umbilical cord blood in controls. Genotyping of polymorphisms was performed using quantitative PCR. There was no statistically significant association ofIRF6gene variants with NSCL/P occurrence, although for rs2013162, AA genotype, odds ratio (OR) = 1.16 and for AC genotype, OR = 0.83; for rs642961, AA genotype, OR = 0.84 and for AG genotype, OR = 1.41; and for rs2235373, AA genotype, OR = 0.79 and for AG, OR = 0.85. In the instance of rs34010 polymorphism inFGF1, the presence of the AA genotype was statistically significant in reducing the risk of NSCL/P (OR = 0.31,p= 0.001). Genetic variation inFGF1is an important risk marker of NSCL/P in the Polish population, which cannot be stated for the polymorphisms in theIRF6gene.

Abstract
We consider a Riemannian manifold (M,g) admitting a concurrent-recurrent vector field for which the metric g is a Yamabe soliton or a τ-quasi Yamabe gradient soliton. We show that if the metric of a Riemannian three-manifold (M, g) admitting a concurrent-recurrent vector field is a Yamabe soliton, then M is of constant negative curvature –α
2. In this case, we see that the potential vector field is Killing. Next, we show that if the metric of a Riemannian manifold M admitting concurrent-recurrent vector field is a non-trivial r-quasi Yamabe gradient soliton with potential function f, then M has constant scalar curvature and is equal to –n(n – 1)α
2. Finally, an illustrative example is presented.
A deep neural network for general scattering matrix

Published: April 2023

Abstract
The scattering matrix is the mathematical representation of the scattering characteristics of any scatterer. Nevertheless, except for scatterers with high symmetry like spheres or cylinders, the scattering matrix does not have any analytical forms and thus can only be calculated numerically, which requires heavy computation. Here, we have developed a well-trained deep neural network (DNN) that can calculate the scattering matrix of scatterers without symmetry at a speed thousands of times faster than that of finite element solvers. Interestingly, the scattering matrix obtained from the DNN inherently satisfies the fundamental physical principles, including energy conservation, time reversal and reciprocity. Moreover, inverse design based on the DNN is made possible by applying the gradient descent algorithm. Finally, we demonstrate an application of the DNN, which is to design scatterers with desired scattering properties under special conditions. Our work proposes a convenient solution of deep learning for scattering problems.

Abstract
The development of architectured nanomaterials has been booming in recent years in part due to their expanded applications in the biomedical field, such as biosensing, bioimaging, drug delivery, and cancer therapeutics. Nanomaterials exhibit a wide variety of shapes depending on both the intrinsic properties of the materials and the synthesis procedures. Typically, the large surface areas of nanomaterials improve the rate of mass transfer in biological reactions. They also have high self-ordering and assembly behaviors, which make them great candidates for various biomedical applications. Some nanomaterials have a high conversion rate in transforming the energy of photons into heat or fluorescence, thus showing promise in cancer treatment (such as hyperthermia) and bioimaging. The nanometric dimension makes them suitable for passing through the biological barriers or interacting with the natural molecules (such as DNA, protein). Nanoflowers, nanotrees, nanostars, and nanodendrites are examples of nano-sized structures, which exhibit unique geometry-dependent properties. Here we reviewed the fabrication methods, features, properties, and biomedical applications of four nano-structured materials including nanoflowers, nanotrees, nanostars, nanodendrites, and nanoleaves. We further provided our perspectives on employing these novel nanostructures as advanced functional materials for a broad spectrum of applications.

Authors: Bolognese Manuel , Karwacki Grzegorz , Österreich Mareike , Müller Martin , Lakatos Lehel 
Published: April 2023

Abstract

Objective
The aim of this study was to ascertain whether dynamic cerebral autoregulation (CA) in the middle cerebral artery (MCA) is disturbed by cerebral infarctions outside the MCA territory.

Methods
We estimated transfer function parameters gain and phase from simultaneous recordings of spontaneous oscillation in blood pressure and MCA cerebral blood flow velocity in 10 consecutive patients with isolated anterior cerebral artery (ACA) infarctions and in 22 consecutive patients with isolated posterior cerebral artery (PCA) infarctions. All ACA infarctions were in the motor, premotor, or supplementary motor cortex areas and presented with pronounced leg hemiparesis. Twenty-eight age- and sex-matched healthy subjects served as controls.

Results
Compared to controls, phase was significantly reduced in the MCA ipsilateral to the lesion site and in the contralateral MCA (unaffected hemisphere) in the very low (0.02–0.07 Hz) and low (0.07–0.15 Hz) frequency ranges in the ACA infarctions but not in the PCA infarctions. Gain was reduced only in the very low frequency range in the MCA contralateral to the ACA lesion site. Systemic factors were unrelated to phase and gain results.

Conclusion
Bilateral impairment of MCA dynamic CA in patients with a unilateral ACA infarction is frequent.

Shopping Behavior and Access to Food in the Areas of Slovakia with Dispersed Settlements: A Case Study
Authors: Trembošová Miroslava , Jakab Imrich , Forgáč Pavel 
Published: April 2023

Abstract
The aim of the research was a spatial and functional analysis of the accessibility of retail food environments in relation to the inhabitants of dispersed settlements who are socially and geographically disadvantaged in purchasing g food. The consumer behavior and food shopping habits of the inhabitants of these areas largely depend on the spatial and functional characteristics of the dispersed settlement and the surrounding area. In terms of food consumption, an important determinant is the availability of convenience stores, defined by the economic and physical ability to access food sources. The ability to access stores is strongly influenced by transport options and transport infrastructure. The investigated area belongs to a group of specific areas with dispersed settlements. This type of settlement, typical in the mountains of Slovakia and on the border with the Czech Republic, can also be found around the town of Nová Baňa, located in the west of central Slovakia. This area consists of two towns and 12 municipalities and is referred to as the “Novobanská štálová oblasť ”. These specific territories are characterized by a lack of access to fresh and affordable food, which can contribute to social disparities in diet and endanger people's health with various serious diseases. Spatial identification of areas with difficult access to food stores in the Novobanská štálová area has been a pioneering attempt to visualize areas with the highest demand for improvement in food access, and this process may be helpful in identifying other areas with similar characteristics. The methods utilized represent an accessible, transparent and reproducible process for assessing the accessibility of grocery stores. These methods can be used for cost-effective, periodic surveillance and meaningful engagement with communities, retailers and policy makers. The conclusions and results of our research should positively contribute to the growing debate on the inequality of living conditions and marginalization of rural municipalities.
The Globalization of Cashless Transactions Using Blockchain Technology to Preventing Money Laundering and The Changing Trends in The Cryptocurrency Market: A Learning Experience of Polish and EU Laws
Authors: Thommandru Abhishek , Chakka Benarji 
Published: April 2023

Abstract
Summary
The COVID-19 pandemic experience has driven us to rely on technology so much on the development and expansion of technology, including cashless transactions. Criminal groups may become more interested in electronic payments and virtual currencies because of increased traffic in these areas. When comparing the second half of the 2019 to the first half of the 2020, the number of fraudulent card transactions increased by 11.4%. New developments in virtual currency trading regulations, including the digital finance package, which includes, among other things, a draught regulation from the European Parliament and an amended act to combat money laundering and terrorist financing, among others. For the reasons stated above, these regulations may lead to a virtual currency market collapse and the withdrawal of investors and the siphoning of money into Asian markets as a result. The current regulations are a manifestation of total regulation and do not encourage technological advancement.

Published: April 2023

AbstractSummaryDuring the COVID-19 unexpected pandemic crisis, to minimalize socio-economic damages within the Member States, the European Commission has taken several steps to increase the flexibility of the support framework and include more diversified forms of aid and extended time-frames for granting them. Implementing urgent measures, in particular for the sectors that are mostly affected by the economic shock and unpredicted limitations pushed them to increase their resilience to be more stable for emergencies. In order to ensure the EU internal market is not fragmented and the level of playing field stays intact, as well as to avoid harmful subsidy races to the detriment of cohesion within the Union, the use of State Aid proved its necessity in various diversified forms of aid. The article discusses State Aid in the context of the global pandemic and tries to find out raised questions.
A Comparison of Cadastre in Slovakia and Poland

Published: April 2023

Abstract
Many analogies can be drawn from the cadastre in Poland and Slovakia, because of the partly shared history of the Austro-Hungarian Empire, World Wars I and II, and the influence of the Communist regime. However, its development over the years has taken different forms and rules of operation in both countries. Currently, from a European perspective, there are efforts to standardise cadastral systems to expand their functionality for land administration and to accommodate social needs.
The aim of this article is to discuss and provide a detailed comparative analysis of the general principles of the cadastre in Slovakia and Poland. The study shows similarities but also many differences between the systems in both countries, which indicates that it could be a difficult path to unify the cadastral systems within the European Union. A comparison of the solutions used in other countries allows us to see potential opportunities for the development and modernisation of the existing cadastral systems.

Abstract
Dam incidents and failures mainly occur during extreme floods. In the Czech Republic (CR), large-scale regional floods were recorded in different regions in 1985, 1987, 1997, 2002, 2006, 2010, and 2013, while local floods especially occurred in 1991, 1996, 1997, 1998, 2002, 2004, 2005, 2009, and 2010. During these events, numerous incidents and total breaches of small dams were recorded, and a few large dams were also critically endangered, although they were not completely breached. This paper presents a comprehensive summary of incidents and failures affecting small dams in the CR since 1985. The most significant incidents concerning large dams are listed as well. The statistics show that 62 small dams were completely breached and that 350 were seriously damaged over 35 years in the period 1985–2020. The annual frequency amounts to 1.85 collapsed and 10 small damaged dams per year. The most common causes of the complete breaching of dams were overtopping (85 %) and internal erosion (15 %).

Authors: Estabraq Ali Hameed  
Published: April 2023

Evaluation of the chemical compounds formed during the process of sterilizing water with chlorine is a very important point. During sterilization the water goes through three stages each stage resulting different chemical compounds. In the first stage, chlorine reacts with iron, magnesium and nitrates. In the second stage it reacts with ammonia and in the third stage it reacts with the organic compounds in the water. Chlorine in these three stages is called combined chlorine. Then it reaches the breaking point, after this point the water must be free from side chemical compounds, and chlorine after this point is called the residual free Chlorine. Drinking water samples were taken from 3 city in Kirkuk governorate, and the concentrations of magnesium, nitrate, sulfate, acetic acid derivatives, as well as the halomethane group in addition to some physical determinants were evaluated.
There were deviations in some chemical concentrations when comparing the results with the last Iraqi specification NO. 417. The deviations that appeared in some concentrations were treated by using two chemical methods, the first using activated carbon and the second using aluminum chloride polymer. The importance of the study is to ensure the effectiveness of chlorine by eliminating chemical compounds dangerous in the water.
