Phase retrieval based on the vectorial model of point spread function
Authors: Hieu Thao Nguyen , Soloviev Oleg , Verhaegen Michel
Published: December 2019

We present an efficient phase retrieval approach for imaging systems with high numerical aperture based on the vectorial model of the point spread function. The algorithm is in the class of alternating minimization methods and can be adjusted for applications with either known or unknown amplitude of the field in the pupil. The algorithm outperforms existing solutions for high-numerical-aperture phase retrieval: (1) the generalization of the method of Hanser et al., based on extension of the scalar diffraction theory by representing the out-of-focus diversity applied to the image by a spherical cap, and (2) the method of Braat et al., which assumes through the use of extended Nijboer–Zernike expansion the phase to be smooth. The former is limited in terms of accuracy due to model deviations, while the latter is of high computational complexity and excludes phase retrieval problems where the phase is discontinuous or sparse. Extensive numerical results demonstrate the efficiency, robustness, and practicability of the proposed algorithm in various practically relevant simulations.
Temporal coherence and polarization modulation of pulse trains by resonance gratings
Authors: Pesonen Henri , Li Peng , Setälä Tero , Turunen Jari
Published: December 2019

We analyze the effects of subwavelength-period resonance gratings on temporally partially coherent optical plane-wave pulse trains. The interaction of the grating with pulses is simulated with the Fourier modal method and finite-difference time-domain method whose performances are compared. Both TE and TM linearly polarized Gaussian Schell-model pulse trains are examined, and partial temporal coherence is modeled with the identical elementary-pulse method. The polarization-dependent response of the grating is seen to lead to significant variations in the average intensity, polarization properties, and degree of temporal coherence of the reflected (and transmitted) pulse trains when the coherence time and polarization state of the incident field are altered. As an important example, we demonstrate that a fully polarized incident pulse train can become partially polarized in grating reflection. The results find use in tailoring of random electromagnetic pulse trains.
Highly resolved ultra-strong coupling between graphene plasmons and intersubband polaritons
Authors: Pisani Francesco , Zanotto Simone , Tredicucci Alessandro
Published: December 2019

The interaction between graphene surface plasmons and a semiconductor
quantum well has been investigated by means of scattering matrix
simulations. Due to the strong confinement factor of the graphene
layer, a large Rabi splitting arises from the interaction with
intersubband transitions. By varying the Fermi energy in the graphene
and the doping in the quantum well, the resulting polariton states
show features of strong and ultra-strong coupling. The system has been
modeled with the coupled-mode theory to find the highest quality
factor for the polariton resonance, reaching a “highly resolved”
ultra-strong coupling regime.

Published: December 2019

Triple-negative breast cancer (TNBC) is a heterogeneous group of breast cancer and is characterized by aggressiveness and poor prognosis. MicroRNA represents a new class of biomarkers, and accumulating evidence indicates that microRNAs contribute to tumorigenesis and cancer metastasis. It has been described that miR-210 is highly expressed in TNBC, and its overexpression had been linked to poor prognosis. In a previous work, we showed that in TNBC miR-210 is expressed in tumor cells and also in the tumor microenvironment (TME), particularly in inflammatory CD45-LCA positive cells. However, the exact identity of these cells remained unknown. In this study, we performed in situ hybridization and immunohistochemistry using validated antibodies for the different specific immune cell markers on adjacent sections of 23 TNBC infiltrated with immune cells. We found that miR-210 expressing cells in the TME were stained positive with CD79a, a B-cell lineage marker. These tumor-infiltrating cells were negative for CD20 and Ki-67 but positive for MUM1 and CD38 and also expressed immunoglobulins, indicating that they are immunoglobulin-producing plasma cells (PCs). To the best of our knowledge, this is the first study demonstrating miR-210 expression in tumor-infiltrating PCs.

Considered the use in the production of aviation equipment (airplanes and helicopters), polymer composites differing in enhanced operational and technological properties, such as strength, rigidity, level of working temperatures, etc. Examples are given of using newer gliders in multilayer structures MS-21 aircraft and Mi-38 helicopter of modern composite materials. The review of defects of multilayer structures made of polymer composite materials arising at the stage of manufacturing, storage, transportation and operation of aircraft, and low-frequency methods of their control is presented. It is noted that the main of low-frequency control methods are the impedance method and the method of free oscillations proposed by domestic scientists.The principle of operation of the first portable multifunctional computerized pulsed flaw detector DAMI-C09, combining impedance, impact and eddy current ND methods, is described. It is noted that the flaw detector can be used for manual and automated, as part of a robotic complex, to identify bundles, nonglues and other violations of the integrity of composites, honeycomb structures and glued structures, to determine corrosion centers, surface and internal defects in non-ferromagnetic materials. A feature of the flaw detector is the simplified preparation process for work due to the automated mode of tuning the signal in amplitude or phase using a spectrum analyzer, documenting the monitoring results with the ability to transfer to a computer and subsequent processing with the help of a special APM of the Flaw Detector. Examples of the effective use of the flaw detector in the production and operation of aviation equipment are given.
Variables individuales, sociodemográficas e institucionales asociadas a la retención de estudiantes de primer año del Programa Académico de Bachillerato de la Universidad de Chile

Published: December 2019

La retención en Educación Superior Universitaria (ESUP) en América Latina y el Caribe (ALC) tiene importantes efectos sociales, económicos e individuales (Proyecto ALFA-GUIA, 2013; CINDA, 2006). La retención ha alcanzado relevancia técnica en los estudios de calidad en la educación, al mismo tiempo que aumenta su importancia en los rankings internacionales y en las acreditaciones de las instituciones universitarias. De acuerdo a un estudio del Banco Mundial (Ferreyra et al., 2017) la ESUP en la región se caracteriza por: 1) una tasa de finalización promedio de 46%, con importantes diferencias entre un país y otro; 2) la existencia de un aumento exponencial de las matrículas, duplicando la tasa regular de estudiantes; 3) el ingreso de “nuevos estudiantes”, anteriormente subrepresentados en la ESUP. Considerando que en la región son escasas las investigaciones que intentan predecir el fenómeno de la retención (Munizaga, Cifuentes & Beltrán, 2018), este estudio busca revisar la información reciente respecto a la retención en ALC, consensuar una definición sobre el fenómeno y ampliar la discusión sobre cómo garantizar la retención de estudiantes en una ESUP equitativa e inclusiva (Espinoza, González & Latorre, 2009). En concreto, este trabajo busca responder ¿Cuáles son las variables individuales, sociodemográficas e institucionales asociadas a la retención de estudiantes de primer año del Programa Académico de Bachillerato de la Universidad de Chile? A través de un modelo de regresión logística binaria, compuesto por ocho variables, se identificaron las siguientes seis variables significativas jerarquizadas: origen étnico de los estudiantes, aprobación de todos los créditos y gratuidad, con una relación positiva con la retención; y preferencia, género y puntaje de la prueba de selección universitaria, con una relación negativa. Las principales recomendaciones de este estudio son, a nivel institucional, ofrecer trayectorias académicas más amplias y, a nivel estatal, hacerse responsable del financiamiento de los estudiantes.
Beyond dipolar Huygens’ metasurfaces for full-phase coverage and unity transmittance

Metasurfaces made from densely packed resonant wavelength-scale particles enable abrupt modulation of impinging electromagnetic radiation within an ultrathin surface. Combining duality symmetry of particles and rotational symmetry of their arrangement led to the development of Huygens’ metasurfaces with perfect transmission. However, so far, when identical particles are considered, only their dipolar multipolar contributions are engineered. There, the achievable phase coverage at a fixed wavelength when modifying the period is smaller than 2π, being a clear limitation for applications. To lift such limitation, we consider dipolar-quadrupolar Huygens’ metasurfaces. They consist of scatterers that require a dipolar and a quadrupolar term to capture their response. We show that such metasurfaces offer access to the desired 2π phase coverage while preserving the perfect efficiency when the conditions of duality and symmetry continue to be met. We also propose core-multishell and disk-multiring particles made from realistic materials to meet the requirements and that can be used to build such metasurfaces. Our results are important as a theoretical basis for large-scale fabrications in imaging and integrated optics.
Physical origin of chemical periodicities in the system of elements
Authors: Cao Chang-Su , Hu Han-Shi , Li Jun , Schwarz W. H. Eugen
Published: December 2019

The Periodic Law, one of the great discoveries in human history, is magnificent in the art of chemistry. Different arrangements of chemical elements in differently shaped Periodic Tables serve for different purposes. “Can this Periodic Table be derived from quantum chemistry or physics?” can only be answered positively, if the internal structure of the Periodic Table is explicitly connected to facts and data from chemistry. Quantum chemical rationalization of such a Periodic Tables is achieved by explaining the details of energies and radii of atomic core and valence orbitals in the leading electron configurations of chemically bonded atoms. The coarse horizontal pseudo-periodicity in seven rows of 2, 8, 8, 18, 18, 32, 32 members is triggered by the low energy of and large gap above the 1s and nsp valence shells (2 ≤ n ≤ 6 !). The pseudo-periodicity, in particular the wavy variation of the elemental properties in the four longer rows, is due to the different behaviors of the s and p vs. d and f pairs of atomic valence shells along the ordered array of elements. The so-called secondary or vertical periodicity is related to pseudo-periodic changes of the atomic core shells. The Periodic Law of the naturally given System of Elements describes the trends of the many chemical properties displayed inside the Chemical Periodic Tables. While the general physical laws of quantum mechanics form a simple network, their application to the unlimited field of chemical materials under ambient ‘human’ conditions results in a complex and somewhat accidental structure inside the Table that fits to some more or less symmetric outer shape. Periodic Tables designed after some creative concept for the overall appearance are of interest in non-chemical fields of wisdom and art.

Published: December 2019

Due to their great importance in science, technology, and the life sciences, water and ice have been extensively investigated over many years. In particular, hexagonal ice Ih has been of great interest since it is the most common form of ice, and several modifications, Ih(a), Ih(b) and Ih(c) are known, whose structural details are still under discussion. In this study, we present an alternative theoretical model, called Ih(d), for the hexagonal ice modification in space group P63/mmc (no. 194), based on first-principles calculations that have been performed using DFT-LDA, GGA-PBE, and hybrid B3LYP and PBE0 functionals.

The compound Cs[OCN] has been synthesized and its crystal structure and Raman spectrum were determined on selected single crystals. As postulated in earlier work, the title compound crystallizes isopointal to KN3 exhibiting the space group I4/mcm (no. 140, Z = 4) with the lattice parameters a = 653.79(2) and c = 799.42(5) pm. The Raman spectrum verified the nature of the triatomic moiety and shows the frequencies typical for an [OCN]− anion with Fermi resonance between the 2δ and the ν
sym vibrations. The undisturbed frequencies and the resulting force constants have been calculated and compared to those of other alkali metal compounds containing comparable linear triatomic anions.
A New Theory of Gender Dysphoria Incorporating the Distress, Social Behavioral, and Body-Ownership Networks
Authors: Gliske Stephen V.
Published: December 2019

When postmortem studies related to transgender individuals were first published, little was known about the function of the various identified nuclei. Now, over 2 decades later, significant progress has been made associating function with specific brain regions, as well as in identifying networks associated with groups of behaviors. However, much of this progress has not been integrated into the general conceptualization of gender dysphoria in humans. I hypothesize that in individuals with gender dysphoria, the aspects of chronic distress, gender atypical behavior, and incongruence between perception of gender identity and external primary sex characteristics are all directly related to functional differences in associated brain networks. I evaluated previously published neuroscience data related to these aspects and the associated functional networks, along with other relevant information. I find that the brain networks that give individuals their ownership of body parts, that influence gender typical behavior, and that are involved in chronic distress are different in individuals with and without gender dysphoria, leading to a new theory—that gender dysphoria is a sensory perception condition, an alteration in the sense of gender influenced by the reflexive behavioral responses associated with each of these networks. This theory builds upon previous work that supports the relevance of the body-ownership network and that questions the relevance of cerebral sexual dimorphism in regard to gender dysphoria. However, my theory uses a hierarchical executive function model to incorporate multiple reflexive factors (body ownership, gender typical/atypical behavior, and chronic distress) with the cognitive, reflective process of gender identity.

Published: December 2019

Transcription factors critical for the transition of normal breast epithelium to ductal carcinoma in situ (DCIS) and invasive breast cancer are not clearly defined. Here, we report that the expression of a subset of YAP‐activated and YAP‐repressed genes in normal mammary and early‐stage breast cancer cells is dependent on the nuclear co‐activator AIB1. Gene expression, sequential ChIP, and ChIP‐seq analyses show that AIB1 and YAP converge upon TEAD for transcriptional activation and repression. We find that AIB1‐YAP repression of genes at the 1q21.3 locus is mediated by AIB1‐dependent recruitment of ANCO1, a tumor suppressor whose expression is progressively lost during breast cancer progression. Reducing ANCO1 reverts AIB1‐YAP‐dependent repression, increases cell size, and enhances YAP‐driven aberrant 3D growth. Loss of endogenous ANCO1 occurs during DCIS xenograft progression, a pattern associated with poor prognosis in human breast cancer. We conclude that increased expression of AIB1‐YAP co‐activated targets coupled with a loss of normal ANCO1 repression is critical to patterns of gene expression that mediate malignant progression of early‐stage breast cancer.
POnline: An Online Pupil Annotation Tool Employing Crowd-sourcing and Engagement Mechanisms
Authors: Gil de Gómez Pérez David , Bednarik Roman
Published: December 2019

Pupil center and pupil contour are two of the most important features in the eye-image used for video-based eye-tracking. Well annotated databases are needed in order to allow benchmarking of the available- and new pupil detection and gaze estimation algorithms. Unfortunately, creation of such a data set is costly and requires a lot of efforts, including manual work of the annotators. In addition, reliability of manual annotations is hard to establish with a low number of annotators. In order to facilitate progress of the gaze tracking algorithm research, we created an online pupil annotation tool that engages many users to interact through gamification and allows utilization of the crowd power to create reliable annotations \cite{artstein2005bias}. We describe the tool and the mechanisms employed, and report results on the annotation of a publicly available data set. Finally, we demonstrate an example utilization of the new high-quality annotation on a comparison of two state-of-the-art pupil center algorithms.

The contribution of snow avalanches to the seasonal snow accumulation on a glacier is among the least studied components of the glacier’s mass balance. The methods for the numerical assessment of avalanche accumulation are still under development, which is related to poor avalanche data availability and difficulties in obtaining such data on most of mountain glaciers. We propose a possible methodology for the numerical assessment of snow avalanche contribution to snow accumulation at mountain glaciers based on DEM and weather data analysis using GIS and numerical modeling of snow avalanches. The developed methodology consists of the following steps: terrain analysis; weather data analysis; snow avalanche volume assessment during an analyzed balance year; numerical simulation of snow avalanches using RAMMS; evaluation of snow avalanches contribution into a glacier accumulation. The proposed methodology was tested on three glaciers located in the Inner Tien Shan: Batysh Sook, № 354 and Karabatkak during the 2015/16 balance year. To evaluate snow avalanche contribution to the seasonal accumulation, we reconstructed avalanche release zones that were most probably active during the 2015/16 balance year and corresponding snow fracture height in each of these zones. The numerical simulations of most probable released snow avalanches during the winter period 2015/16 using avalanche dynamics software RAMMS were performed and compared with the field observations and UAV orthophoto image from July 2016. The outlines of avalanches deposits were realistically reproduced by RAMMS according to the results of field observation. The estimated share of snow avalanche contribution to the accumulation on the research glaciers during the 2015/16 balance year turned out to be: Batysh Sook – 7,4±2,5%; № 354 – 2,2±0,7%; Karabatkak – 10,8±3,6% of the total accumulation. The next step would be to test the proposed methodology based on the data and regional dependences from the Inner Tien Shan in other mountainous regions. This methodology is applicable in the regions where DEMs, regular meteorological observations as well as data on the regional avalanche formation factors are available.

MEALS OF THE BOUNDARIES COMMISSION IN LVIV (1578, 1579, 1581) ON THE EXAMPLE OF A SOURCE - THREE FRAGMENTS FROM THE LVIV WEEKLY-EXPENDITURES BOOKS. TRANSLATION. COMMENTS
Authors: Левус Назар
Published: December 2019

In the second half of the 16th century in Lviv were conducted meeting of the Border Commission. The Commission resolved the controversial questions related to the land issue and ordering its boundaries. During its implementation, city delegates and commissioners often stopped for rest and lunch. Meat, fish, bread, various spices and wine were accompanied participants of the Borders Commission during joint meetings, whether at the City Hall or outside it.This and other information is vividly illustrated by a source such as the Lviv weekly-expenditures book for 1572–1582. This source has big information potential. In the Lviv weekly-expenditures books you can find information about the activities of the city authorities (councils and benches of the city of Lviv); the acomplishment of functions by city officials (such as the executioner); routine affairs in the city, etc. This publication provides three fragments of the source of the Boundary Commission meeting for 1578, 1579, 1581.The Boundary Commission of 1578 was held on the eve of the Birthday of John the Baptist (June 24) and lasted from June 20 to June 23, 1578. The source does not provide specific details of the dispute, but it can be assumed that a soil dispute arose between a monastic order of Lviv Dominicans and Bryukhovychi peasants. During the joint lunches and dinners in the suburban tavern in Bryukhovychi, for four days, the commissioners drank three barrels of beer, 22 jugs (85 liters) of Hungarian wine, consumed veal; fish and herrings (most likely eaten on Friday June 22); bread and other dishes cooked for them.In 1579, the Commission resolved the disputed issues between the city and Lviv’s podstoli, Joakim Samp. During its meeting on the second Sunday of Lent in 1579, were present Lviv’s castellans Stanislav Herburth and Lviv starosta Mykola Herburth. Each of them was presented with 8 jugs of Malvasia for greetings. To feed the delegates were purchased variety of fish, bread, spices, vegetables, condiments and 27 jugs of Malvasia. It is interesting that the Commissioners did not consume meat under the Border Commission because it took place during Lent.The Borders Commission, in October 1581, was also involved in resolving the dispute between Joachim Samp and the community of Lviv. The meetings of the Commission were followed by lavish dinners. In particular, to the borders that were checked was bought 2 barrels of beer, two-quarters of meat, 5 chickens, bread, various roots. On Tuesday, October 13, 1581, all the commissioners and guests, including Mykola Herburt, the Lviv starosta and Mykola Meletsky, the Podolsk voivode, and all their servants were gratulated in Sikhiv Korchma. For festive supper was bought two calves, four quarters of meat, 2 barrels of beer, rye and white bread, vegetables, lemons, raisins, sugar, 4 vessels of jam, 35 ½ jugs of wine and 6 jugs of alicakantu.
“ACCORDING TO THE BROTHERHOODS’ CUSTOM” BANQUETS OF KYIV CRAFTSMEN OF THE SECOND HALF OF XVIII CENTURY
Authors: Sokyrko Oleksii
Published: December 2019

Nutrition has always been an important element of the subculture of different social communities of Early Modern Europe. Holiday feasts of craftsmen corporations in the cities performed symbolic functions, separating the socio-professional community from the rest of society, and at the same time demonstrated its status, wealth, prestige. The joint banquets of craftsmen on the occasion of church holidays and corporate events strengthened group identity, saved it from blurring, restrained the isolation and individualization of its members. The several-day banquets held after the church liturgies were accompanied by music and hearty feasts, gifts to the clergy patrons of the craft and magistrate officials, and demonstrated the material power of the craft brotherhood and the respectful social status of its members.

The books of Kyiv craft corporations allow to reconstruct the middle-class townsfolk cuisine of the middle - second half of the 18th century. According to the expenditure registers contained in them, it is evident that the townsfolk gastronomic tradition retained all the features inherent in the late medieval food system. It was dominated by the meals and drinks that formed the basis of nutrition for the high and the middle-class: large amounts of meat, fresh and salted fish, thick crunchy soups and cereals, white bread, vodka (horilka), mead and beer.

The culinary culture of craftsmen was no stranger to imitation of higher gastronomic patterns and habits. In early modern Kyiv, the monastic world and the everyday culture of the church hierarchs acted as a model for imitation. This is where the artisans borrowed their taste for the use of tea, caviar and sturgeon. Another model to follow was the merchants, whose table was rich in various spices, imported alcohol, vegetables, fruits and sweets. Less significant, but noticeable, was the influence of the household fashion of the Cossack officials (starshyna) and the LittleRussian nobility (shliakhta): wildfowl, lavish local and imported liquers (vodka) appeared on the townspeople's tables. For all its ostentatious personality and efforts to imitate the cuisine of the upper classes, the food style of the craftsmen was far from cosmopolitanism. In the kitchen of Kyivites we will not see manifestations of culinary fashion of the XVIII century. The periphery of Kyiv's economic and administrative status made the food of its inhabitants quite typical of the rest of the country, having preserved the noticeable features of the food structure that had been developed in the previous XVII century. In the case of craft corporate records, we can see literally microscopic changes - the appearance of cheap spices, sugars, inexpensive imported wines in the diet of burghers, which were markers of sluggish economic changes
BETWEEN CITY AND VILLAGE: FOOD CONSUMPTION PRACTICES IN THE EVERYDAY LIFE OF THE UKRAINIAN INTELLIGENTSIA (THE LATE 19th – EARLY 20th CC.)
Authors: Kazakevych Olga
Published: December 2019

The article is devoted to the food consumption practices of the Ukrainian-minded educated class during the late 19th – early 20th cc. It is based mainly on the memoirs and diaries. The author considers the fact that the intelligentsia was a relatively new social stratum which came into being by the middle of the 19th c. Most of its representatives, whether they were descendants of gentry or peasants, originated from the non-urban area. The Ukrainian-minded intellectuals maintained their connections with the countryside and its culture, spending their vacations in the rural area, hiring former peasants as cook-housekeepers etc. The author assumes that this was the main reason why the tastes and food habits of Ukrainian intelligentsia were to a large extent influenced by the traditional rural cuisine. It is clearly visible in the descriptions of the Christmas and Easter celebrations when mostly traditional dishes used to be cooked. Keeping a fast was also a common practice for both Orthodox rural population and the urban intelligentsia. As the author points out, meetings of the Ukrainian-minded intellectuals in Kyiv were usually accompanied by the feasts and banquets. At these banquets, the demonstration of hospitality and largess was highly important and the dishes of people’s cuisine (recognized as national and democratic) were especially popular. However, a new experience of consuming international food and drinks in the urban milieu progressively transformed tastes of the Ukrainian intelligentsia. Travelling abroad contributed significantly to the changing of domestic food practices. In general, the author comes to the conclusion that during the late 19th – early 20th cc. food consumption practices of the Ukrainian intelligentsia used to be a mixture of the Ukrainian gastronomic traditions and international (mostly European) cuisine.
Factors Influencing Career Longevity in Pediatric Hospital Medicine
Authors: House Samantha , Frintner Mary Pat , Leyenaar JoAnna K.
Published: December 2019

BACKGROUND AND OBJECTIVES:

Pediatric hospital medicine (PHM) is a growing field recently approved by the American Board of Pediatrics as a subspecialty. Understanding factors associated with hospitalist retention is important for workforce planning. Our objective for this study was to examine the proportion of pediatric hospitalists who remained in PHM over a 5-year period and identify factors associated with retention.

METHODS:

We used 2012 and 2016 data from the American Academy of Pediatrics’ Pediatrician Life and Career Experience Study. Retention was defined as being a self-reported hospitalist on both surveys. χ2 tests were used to examine relationships between retention and variables within 3 categories: demographics, position-related factors, and factors related to stress and satisfaction. A multivariable logistic regression was used to further assess relationships between select factors and retention.

RESULTS:

In 2012, 206 of 1804 survey respondents were hospitalists (11%); 180 of these 206 individuals responded again in 2016, and 122 (68%) remained hospitalists. In the multivariable analysis, individuals earning ≥$175 000 were more likely than those earning less (adjusted odds ratio [aOR] = 3.93; 95% confidence interval [CI]: 1.26–12.25) and those more satisfied with their job were more likely than those less satisfied (aOR = 3.28; 95% CI: 1.22–8.80) to remain hospitalists. Respondents with more concern about educational debt were less likely than those less concerned to remain hospitalists over 5 years (aOR = 0.42; 95% CI: 0.20–0.90).

CONCLUSIONS:

Two-thirds of early- to mid-career hospitalists remained in PHM 5 years later. Financial factors and job satisfaction appear to play an important role in retention; consideration should be given to the impact of these factors on the PHM workforce.
The Effect of Preterm Birth on Renal Development and Renal Health Outcome
Authors: Dyson Amanda , Kent Alison L.
Published: December 2019

Preterm birth is associated with adverse renal health outcomes including hypertension, chronic kidney disease, and an increased rate of progression to end-stage renal failure. This review explores the antenatal, perinatal, and postnatal factors that affect the functional nephron mass of an individual and contribute to long-term kidney outcome. Health-care professionals have opportunities to increase their awareness of the risks to kidney health in this population. Optimizing maternal health around the time of conception and during pregnancy, providing kidney-focused supportive care in the NICU during postnatal nephrogenesis, and avoiding accelerating nephron loss throughout life may all contribute to improved long-term outcomes. There is a need for ongoing research into the long-term kidney outcomes of preterm survivors in mid-to-late adulthood as well as a need for further research into interventions that may improve ex utero nephrogenesis.

The empirical results reveal a relatively high short-run interest pass-through of 0.724100 and a marginally overshooting long-run interest rate pass-through of 1.054309. The bounds test results indicate a strong long-term relationship between countercyclical monetary policy and market rates. These empirical findings suggest that the National Bank of Ukraine has been very effective in formulating and implementing its countercyclical monetary policy, in spite of the pervasive corruption, formidable political and economic challenges faced by the Ukrainian Republic over this sample period, the results are quite surprising.

This paper presents a new, simple, precise, and accurate rapid resolution liquid chromatography (RRLC) method for determination of an active ingredient malathion in the pesticide formulation. The analysis was performed on a Poroshell EC 120-C18 (50 mm × 3 mm, 2.7 μm) analytical column using isocratic elution with a mobile phase consisted of acetonitrile–water (50:50, v/v), a flow rate of 1 mL/min, a constant column temperature at 25 °C, and ultraviolet-diode array detection (UV-DAD) at 220 nm. The specificity, selectivity, linearity, precision, and accuracy were tested for the method validation according to the Collaborative International Pesticides Analytical Council (CIPAC) and Directorate General Health and Consumer Protection (SANCO) guidelines and all tested parameters were found within acceptance criteria. The obtained results indicated that the proposed method can be used for routine analysis of the active ingredient malathion in the pesticide formulation “Etiol tecni” following the CIPAC and SANCO rules. The run time of analysis under the stipulated chromatographic conditions was about 2.5 min, meaning that the proposed method requires a small volume (< 1.5 mL) of the organic solvent (acetonitrile) making it cost-effective.

Purple nonsulfur bacteria are a group that has so much biotechnological applications, particularly in producing of functional food rich with unsaturated fatty acids. A purple nonsulfur bacterium (named HPB.6) was chosen based on its strong growth, high lipid and synthesis of unsaturated fatty acid (omega 6,7,9). Studying on basic biological characteristics showed that the cells of HPB.6 were observed as ovoid-rod shape, none motility, Gram negative staining. The diameter of single bacterium was about 0.8-1.0 µm. The cells divide by binary fission and had bacteriochlorophyll a (Bchl a). This bacterium grew well on medium with carbon and nitrogen sources such as acetate, succinate, pyruvate, butyrate, glutamate, arginine, leucine, tyrosine, alanine, methionine, threonine, glutamine, yeast extract and NH4Cl. This selected strain grew well on medium with salt concentrations from 1.5 - 6.0% (optimum 3%), pH from 5.0 to 8.0 (optimum at pH 6.5) and could withstand Na2S at 4.0 - 5.2 mM. Based on morphological, physiological properties and 16S rRNA analysis received demonstrated that HPB.6 strain belongs to the species Rhodovulum sulfidophilum.

A new structure of a micro-strain beam type of Micro-Electro-Mechanical-Systems (MEMS) strain gauge is proposed and simulated. The stress and strain distributions of MEMS strain gauge are evaluated in x and y directions by 2D FEM simulation, respectively. The results showed that the longitudinal stress and strain distributions of strain beam enhance significantly, while the transverse stress and strain distributions are almost unchanged in the whole structure of MEMS strain gauge. High sensitivity of piezoresistive MEMS strain sensors can be designed to detect only one single direction of the stress and strain on the material objects.
SYNTHESIS OF MoS2/GRAPHENE NANOCOMPOSITE BY FACILE ULTRASONIC-ASSISTED HYDROTHERMALMETHOD
Authors: Le Ngoc Long , Pham Trung Kien , Tran Van Khai
Published: December 2019

In this report, thin layers of MoS2 were in-situ incorporated into graphene oxide (GO) to form MoS2/graphene nanocomposite by a facile ultrasonic-assisted hydrothermal method. X-ray Diffraction (XRD) and Raman analysis revealed that the as-synthesized MoS2 nanosheets crystalized in hexagonal phase 2H-MoS2 while High Resolution Transmission Electron Microscopy (HRTEM) images confirmed that MoS2 layers with average thickness of ~5–6 nm (6–8 layers) attached on the edges and surfaces of graphene sheets with high density and uniform shape restacking in three-dimensional (3D) architectures. The Scanning Transmission Electron Microscopy – Energy Dispersive X-ray spectrum (STEM-EDX) investigation further confirmed the low impurity of MoS2/graphene composite, and the well repairing of defects in GO surfaces during the hydrothermal process. Our approach is promising for a scalable, inexpensive, and accurate strategy to fabricate state-of-the-art materials with a certain structure for various practical applications such as electrode material for Lithium battery or supercapacitor.
Efekty makroekonomiczne polityki fiskalnej i monetarnej w gospodarkach Europy Środkowej i Wschodniej

Objective: The aim of this paper is to study the effects of budget balance and money supply on producer price inflation (PPI), the current account balance and the output gap for five Central and East European (CEE) countries (Bulgaria, the Czech Republic, Hungary, Poland and Romania).Research Design & Methods: Based on the quarterly data over the 2000–2017 period, macroeconomic effects of the budget balance and money supply are estimated with the Structural Vector Autoregressive (SVAR) model, which anticipates reliance of the money supply upon the current account balance on impact, with a simultaneous dependence of the latter upon the business cycle.Findings: A budget surplus did not cause any output losses in any of the five CEE countries. For three of the countries (Bulgaria, the Czech Republic, Poland), a budget surplus is associated with decelerating producer price inflation and improvement in the current account balance (the Czech Republic, Hungary, Poland). A budget surplus is likely to bring about an increase in the money supply. Expansionary monetary policy is a factor behind either worsening of the budget balance (Bulgaria, Poland), or a short-lived improvement in it (the Czech Republic, Hungary). Macroeconomic effects of the money supply tend to be heterogeneous, supporting both demand-side and supply-side transmission mechanisms.Implications / Recommendations: Our results favour conservative fiscal and monetary policies in all five of the CEE countries, particularly in the Czech Republic and Poland.Contribution: The scientific contribution of the article is that it justifies the use of the dependent economy model, with output disaggregated into tradable and nontradable sectors, for analysis of economic policy in the CEE countries.
Effect of quality on damage in contiguous pavement sections
Authors: Mallick Rajib B , Kautz Frederick A
Published: December 2019

This paper applies system dynamics to evaluate the effect of quality on damage in contiguous pavement sections. System dynamics models for a multisection stretch of roadways were developed and modified to include the effect of trigger time, delay and the presence of materials of different quality in adjacent sections. The results indicate that the initial quality of a section at a higher elevation and which allows the ingress of water can affect the rate of damage in an adjacent section at a lower elevation and that different sections can have different lives, despite having the same initial quality. The variability of the damage in the adjacent section at the lower elevation, due to the triggering damage in the sections at upper elevations, is much higher than that of the section at a higher elevation. Using an initial higher quality for the section at the lower elevation and ensuring an overall higher quality are the options for ensuring an acceptable rate of damage for all sections. The acceptable difference between the initial quality of the sections at the higher and lower elevations is dependent on the initial quality of the section at the higher elevation.

Critical Constants Correlation from van der Waals Equation
Authors: Martínez Vitela Mario Alberto , Gracia Fadrique Jesús
Published: December 2019

The cubic van der Waals equation of state at the critical condition is reduced to a linear function (Vc vs. Tc /Pc coordinates) with one adjustable parameter. It is shown that at the critical point the relation Vc = 3Vo must not hold as van der Waals suggested, but the attractive constant α = Pc Vc2 remains. Selected values of Tc, Pc, Vc compiled by Ihmels where focused on testing the quality of several empirical equations relating critical conditions. It is shown that the obtained critical constants correlation is a general form of the empirical expressions proposed by Young, Meissner, Bird, Grigoras and Ihmels. From the resulting correlation function, a function for the critical compressibility is proposed. The critical volume Vc and the ratio Tc /Pc have been expressed in group contributions.
