Published: July 2021

The article reflects the consideration of the problem of treatment of combined (longitudinal-transverse) flat feet and the use of various methods of correction of this pathology. The main approaches to the treatment of combined (longitudinal-transverse) flat feet are considered and a brief review of experimental studies and patent developments in relation to the treatment of combined (longitudinal-transverse) flat feet. The analysis of the experience of using various treatment methods for combined (longitudinal-transverse) flat feet in foreign and domestic practice is presented, problematic aspects of the fight against the pathology under consideration are highlighted. It is noted that the separate use of various treatment methods for combined (longitudinal-transverse) flatfoot has insufficient effectiveness and is associated with the risk of re-development of pathology, while the greatest effect in the early stages of the development of combined flatfoot gives the use of complex treatment, using both medication and various orthopedic methods, exercise therapy, and massage. The need for further scientific research in relation to the most effective combination of different treatment methods for combined flat feet was determined, which would give a positive dynamics of changes both in relation to the feet and lower extremities in general, and in relation to the entire musculoskeletal system. The necessity of considering the musculoskeletal system and the feet as a single mechanism, a kinematic chain with degrees of freedom (mobility and deformability in the joint), in which the transfer of reactive or reflected forces in the linking chain of the chain

Authors: Wu Fei , Li Haigang , Cheng Chen , Zhang Hao , Fei Shunxin
Published: July 2021

Cognition to the metal-metal interactions is of vital importance for the catalytic process and would help exploring novel catalysts. In the present study, the model system of FexNiy (x + y = 6) bimetallic clusters was utilized to study how metal-metal interactions influence the catalytic performance. The formation energies of different FeNi clusters, the hydrogen chemisorption energies together with the maximum hydrogen capacity and the saturated hydrogen atoms desorption energies were calculated. Bimetallic clusters exhibit a superior performance than pure clusters. Especially, Fe2Ni4 cluster has the highest hydrogen loading capacity, the most facile hydrogen molecule dissociation activation energy barrier and the lowest hydrogen atom desorption energy, suggesting that it is easier to dissociate H2 and release the H atoms. As a consequence, by adjusting appropriate metal/metal ratios, it is possible to design bimetallic catalysts with excellent catalytic performance.

Published: July 2021

Metal particle could deposited on Nylon 12 (PA12) surface using electroless plating with excellent interface and distribution, but the use of noble metal as catalytic site would increase the process cost and restrict its application. In this work, we employed a facile technology combined with acetic acid etching and electroless copper plating to prepare Cu/PA12 composite powder, and it used as conductive filler for antistatic coating was also studied. Results manifested defects (hole and amorphous structure) and amide group established on etched PA12 surface, which would facilitate the destruction of the [Cu-EDTA] structure, and then the reduction of REDOX barrier. As a result, Cu and Cu2O particles deposited on its surface. The downward trend of volume resistivity of antistatic coating appeared the rule of slow-fast-slow. The lowest volume resistivity was about 105 ohm�cm. This means that the dependable technology has great potential application in preparing metal/polymer composite material at a low cost.

Authors: Abouzeid Fatma. M.
Published: July 2021

Steel electro-dissolution performance was investigated in orthophosphoric acid in the presence of N-oleyl 1.3 diaminopropane, Benzalkounuim chloride, Soduim lauryl sulphate and Di-Isononyl phthalate as a surfactant using potentiodynamic polarization measurements. The retardation performance of these surfactants was examined. The surfactant surface active parameters were estimated based on surface tension measurements. The parameters calculated comprise the critical micelle concentration (CMC), maximum surface excess (Гmax), minimum surface area (Amin) and effectiveness (πCMC). The micellization thermodynamic parameters (ΔGmic, ΔSmic) for the estimated surfactants were also computed. Results obtained from surface active properties are comparable with those gained from galvanostatic polarization measurements. Temperature influence on the steel dissolution performance was examined at 25 to 40oC range. Steel kinetic study in orthophosphoric acid- free solution and orthophosphoric acid containing surfactant was also examined. The dissolution kinetic and activated parameters were computed. Results based on microscopy measurement indicate that, addition of new four surfactants, resulting in the solution shows potential, a discrete progress in the metal texture was monitored. Improvement produced in electro-polishing bath by the investigated SAS that owing to the adsorption of such surface active agents on the anode surface.

How to calculate earthworms using the hand sorting method. The method commonly used for the determination of C-organic is the Walkley and Black method, while the method used for the determination of N-total is the Kjehdahl method. This method is used because it is considered simple, fast, easy to do, and requires little equipment. The results of this study indicate that in horticultural land there is no earthworm population found at all depths. Earthworm populations were found at all depths in the coffee plantation monoculture, the highest population was at a depth of 0-10 cm as many as 41 m2, Biomass was 9 g, and Biomass vs Population 0.21 m2. In horticultural fields, the highest c-organic and n-total is at a depth of 0-10 cm, the c-organic value is 3.03% (high criteria) and n-total is 0.47% (medium criteria). The close relationship between the earthworm population, biomass, and biomass versus population was positively correlated with c-organic and n-total in horticultural land and coffee monoculture.
The Garies wollastonite deposit, Namaqualand, South Africa: High-Temperature metamorphism of a low-δ18O skarn?
Authors: Harris Chris , Maboane Lucrecia
Published: July 2021

The Garies wollastonite deposit is located in the Bushmanland terrane of the Namaqualand Metamorphic Province and is part of a discontinuous calc-silicate unit bounded by granulite facies gneiss that experienced peak metamorphic temperatures above 800 °C. In bulk, the deposit is dominated by wollastonite, but varied proportions of garnet, diopside, quartz, calcite, and vesuvianite are also present. Mineral chemistry variations across the deposit are minor, and the absence of inclusions indicates textural and chemical equilibrium. The wollastonite-bearing rocks have unusually low mineral δ18O values: –0.6 to +2.2‰ for garnet, –0.2 to +2. 6‰ for clinopyroxene, and –0.2 to +0.4‰ for wollastonite. Calcite δ18O values range from 6.8 to 11. 8‰ and δ13C values from –6.4 to –3.2‰. Calcite δ18O values are unusually low for calc-silicate rocks, but Δcalcite-garnet values from 3 to 12‰ indicate O-isotope disequilibrium between calcite and the silicate minerals. Garnet-biotite metapelitic and diopside gneisses have unexpectedly low δ18O values (<7‰). The approach to O-isotope equilibrium displayed by coexisting silicate minerals, and low mineral δ18O values in calc-silicate and metapelite and metapsammite gneisses, is consistent with low δ18O values being acquired before peak metamorphism. Low δ18O values in the minerals of the calc-silicate rocks require interaction with external fluid at high water/rock ratio. We suggest that the deposit represents a metamorphosed skarn that developed at the contact between the original carbonate rocks and intruding felsic magmas.
Chemical and boron isotope composition of tourmaline from pegmatites and their host rocks, Sierra de San Luis, Argentina
Authors: Montenegro Teresita , Wul Julieta , de Luchi Mónica López , Ribacki Enrico , Trumbull Robert B.
Published: July 2021

We report chemical and B-isotope analyses of tourmaline from Ordovician S-type granites, an aplite, LCT-type (lithium-cesium-tantalum) pegmatites, and metamorphic rocks of the Conlara Metamorphic Complex (CMC) in Sierra de San Luis, Argentina. For comparison, tourmaline from three LCT pegmatites in the adjacent Pringles Metamorphic Complex was also studied. Metamorphic tourmaline from the CMC has intermediate schorl–dravite compositions, with variable Fe# [100 * Fe/(Fe + Mg)] from 32 to 79. The δ11B values range from –14.8 to –8.9‰, which are typical values for continental metasediments and granites, ruling out a marine origin for the tourmalinite protoliths. Tourmaline from the S-type granites and aplite is more homogeneous, with Fe# from 48 to 60. The δ11B range (–14 to –9.8‰) of granitic tourmaline is within that of the metamorphic tourmaline, supporting the idea of boron recycling in the CMC during partial melting to form the granites. Tourmaline from CMC-hosted pegmatites is compositionally diverse and we distinguished three groups based on Fe#: Group 1: 42 to 50, Group 2: 50 to 62, and Group 3: 62 to 93. Regardless of strong variations in Fe#, tourmaline from all pegmatites in the CMC has δ11B values from –10.3 to –7.8‰. These values overlap with the range of related granites but are about 2 permil higher, which we attribute to crystallization of 10B-enriched minerals (mica and tourmaline) in the evolved magma from which the pegmatites formed. Pegmatites from the Pringles Metamorphic Complex contain tourmaline with a similar overall range of Fe# (45 to 84) as in the CMC but lower δ11B values (–13.2 to –11.2‰).
Reducing molecular simulation time for AFM images based on super-resolution methods

Published: July 2021

Atomic force microscopy (AFM) has been an important tool for nanoscale imaging and characterization with atomic and subatomic resolution. Theoretical investigations are getting highly important for the interpretation of AFM images. Researchers have used molecular simulation to examine the AFM imaging mechanism. With a recent flurry of researches applying machine learning to AFM, AFM images obtained from molecular simulation have also been used as training data. However, the simulation is incredibly time consuming. In this paper, we apply super-resolution methods, including compressed sensing and deep learning methods, to reconstruct simulated images and to reduce simulation time. Several molecular simulation energy maps under different conditions are presented to demonstrate the performance of reconstruction algorithms. Through the analysis of reconstructed results, we find that both presented algorithms could complete the reconstruction with good quality and greatly reduce simulation time. Moreover, the super-resolution methods can be used to speed up the generation of training data and vary simulation resolution for AFM machine learning.
High Density RDL Technologies for Panel Level Packaging of Embedded Dies
Authors: Boettcher Lars , Kosmider S. , Schein F. , Kahle R. , Ostmann A.
Published: July 2021

The ongoing miniaturization and functional heterogeneity in electronics packaging are pushing the demand for advanced substrate technologies. Highly integrated, advanced multi-chip packaging solutions combine application, logic and computing dies with memory or components for power management in a single package. A solution to achieve low fabrication costs is the close embedding of thin dies in IC Substrates based on large formats (600 x 600 mm²), known from PCB fabrication. In a consortium of partners from industry and research advanced technologies for Panel Level Packaging (PLP) are developed.

This paper will show the development of 5µm L/S RDL routing density and chips with 50µm bump pitch. Here, the 6x6 mm² dies are symmetrically embedded into an organic laminate matrix. A PCB core (100µm thickness) with very low coefficient of thermal expansion (CTE) containing laser cut cavities is used, acting as a frame layer. Besides mechanical and handling stability, the usage of such a frame offers the advantage of pre-integrating additional features like local fiducials, through vias or power lines by conventional PCB processes. Within that frame, the dies are embedded by lamination of an organic build-up film with 25µm thickness equal to bump height. The chip contacts are then opened without the need of any micro via formation. Here a strong focus is set on RIE etching of the polymer material.

Highly accurate measurement of the real die position is essential for the following processing. The formation of the redistribution layer (RDL) is done in a semi-additive process (SAP) utilizing sputtering technique and direct imaging (LDI). To achieve the fine pitch demands, an adaptive imaging process is applied. Therefore, a newly developed LDI machine is used to write structures in a 7µm photoresist. This exposure also combines the measurement data of the real die position and the adaption of the exposure artwork, in order to achieve highest registration quality.
On Agency and Ramparts in the Lower Danube and Spain
Authors: De Man Adriaan
Published: July 2021

Having worked mainly on the late Roman and Visigothic walls of the Spanish provinces, I came across the details of Dacian-Moesian frontier defences mostly by chance, through a book by Carl Schuchhardt and his contributions to linear earthworks. I would like to contrast these valla in the specific angle of agency, as the discussions on the Moldovan wall of Athanaric and its chronology are reminiscent of questions posed as well in southwestern imperial contexts. Although no precise equivalences for such extensive, often river-connected ramparts are known in Hispania, I wish to put a few points in perspective and to establish some not strictly archaeological, but rather interpretive
correspondences. The purpose is framing a meta-analysis for early Gothic defensive concerns, with a focus on large built structures, from the standpoint of their perceived usefulness, as a trigger for agency. The cultural reality of both territories in contrast is entirely distinct, and may therefore provide an interesting approach for the understanding of investment priorities in the genesis of very early medieval monarchies, and their negotiated implementation through transformed imperial mechanisms.

Authors: Lipai Tatyana
Published: July 2021

The relevance of the sociological problems of linguistic studies intensified in the second half of the 20th century, which was caused by social reasons, including the opportunity to use the process of mass learning of foreign languages to spread the strengthening of the policies of individual states. The author has specified the concept of “culture-oriented linguistics” for sociological consideration, since it is understood differently in different sources, and prospects of experimental studying. Within the framework of this study, an emphasis is placed on studying the influence of linguistic and cultural characteristics of communication space, including multilingualism, for the modern specialists. The priority is not just the knowledge of the language, but the development and formation of a multicultural personality. The topic of multiculturalism occupies a special place in the process of acquiring educational competencies.

Published: July 2021

Blazars represent the dominant class of associated γ-ray sources detected by the Fermi Large Area Telescope (LAT). However, in the more recent release of the Fourth Fermi-LAT Point Source Catalog (4FGL), ∼25% of the sources associated with lower-energy counterparts show a multifrequency behavior similar to that of blazars, but lacks an optical spectroscopic confirmation of their nature and are therefore classified as Blazar Candidates of Uncertain Type (BCUs). A particularly challenging task in blazar studies is to classify these BCUs and, when possible to estimate their redshifts, in particular for BL Lac objects, characterized by almost featureless optical spectra with only weak emission lines. Continuing our study of blazars with Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) optical spectral data, we perform an extensive search for optical spectra available in the LAMOST Data Release 6 archive. Our aim is confirming the blazar nature of BCUs and to test if new data can allow us to get a redshift estimate for BL Lac objects that lack measurement, as well as to search for and discover changing-look blazars. We selected sources out of the 4FGL catalog, the list of targets from our follow-up spectroscopic campaign of unidentified and/or unassociated γ-ray sources, and the Roma-BZCAT multifrequency catalog of blazars, finding a total of 42 sources with available LAMOST DR6 spectra. We confirmed the blazar-like nature of four blazar candidates . For the remaining 37 sources we confirm their previous classification.

We present high-angular-resolution imaging observations of 517 host stars of TESS exoplanet candidates using the ‘Alopeke and Zorro speckle cameras at Gemini North and South. The sample consists mainly of bright F, G, K stars at distances of less than 500 pc. Our speckle observations span angular resolutions of ∼20 mas out to 1.″2, yielding spatial resolutions of <10–500 au for most stars, and our contrast limits can detect companion stars 5–9 mag fainter than the primary at optical wavelengths. We detect 102 close stellar companions and determine the separation, magnitude difference, mass ratio, and estimated orbital period for each system. Our observations of exoplanet host star binaries reveal that they have wider separations than field binaries, with a mean orbital semimajor axis near 100 au. Other imaging studies have suggested this dearth of very closely separated binaries in systems which host exoplanets, but incompleteness at small separations makes it difficult to disentangle unobserved companions from a true lack of companions. With our improved angular resolution and sensitivity, we confirm that this lack of close exoplanet host binaries is indeed real. We also search for a correlation between planetary orbital radii versus binary star separation; but, given the very short orbital periods of the TESS planets, we do not find any clear trend. We do note that in exoplanet systems containing binary host stars, there is an observational bias against detecting Earth-size planet transits due to transit depth dilution caused by the companion star.
Evolution of Interplanetary Coronal Mass Ejection Complexity: A Numerical Study through a Swarm of Simulated Spacecraft

In-situ measurements carried out by spacecraft in radial alignment are critical to advance our knowledge on the evolutionary behavior of coronal mass ejections (CMEs) and their magnetic structures during propagation through interplanetary space. Yet, the scarcity of radially aligned CME crossings restricts investigations on the evolution of CME magnetic structures to a few case studies, preventing a comprehensive understanding of CME complexity changes during propagation. In this Letter, we perform numerical simulations of CMEs interacting with different solar wind streams using the linear force-free spheromak CME model incorporated into the EUropean Heliospheric FORecasting Information Asset model. The novelty of our approach lies in the investigation of the evolution of CME complexity using a swarm of radially aligned, simulated spacecraft. Our scope is to determine under which conditions, and to what extent, CMEs exhibit variations of their magnetic structure and complexity during propagation, as measured by spacecraft that are radially aligned. Results indicate that the interaction with large-scale solar wind structures, and particularly with stream interaction regions, doubles the probability to detect an increase of the CME magnetic complexity between two spacecraft in radial alignment, compared to cases without such interactions. This work represents the first attempt to quantify the probability of detecting complexity changes in CME magnetic structures by spacecraft in radial alignment using numerical simulations, and it provides support to the interpretation of multi-point CME observations involving past, current (such as Parker Solar Probe and Solar Orbiter), and future missions.

Manual fits to spectral times series of Type Ia supernovae have provided a method of reconstructing the explosion from a parametric model but due to lack of information about model uncertainties or parameter degeneracies direct comparison between theory and observation is difficult. In order to mitigate this important problem we present a new way to probabilistically reconstruct the outer ejecta of the normal Type Ia supernova SN 2002bo. A single epoch spectrum, taken 10 days before maximum light, is fit by a 13-parameter model describing the elemental composition of the ejecta and the explosion physics (density, temperature, velocity, and explosion epoch). Model evaluation is performed through the application of a novel rapid spectral synthesis technique in which the radiative transfer code, TARDIS, is accelerated by a machine-learning framework. Analysis of the posterior distribution reveals a complex and degenerate parameter space and allows direct comparison to various hydrodynamic models. Our analysis favors detonation over deflagration scenarios and we find that our technique offers a novel way to compare simulation to observation.
Testing the Speed of Light Variation with Strong Gravitational Lensing of SNe 1a
Authors: Gupta Rajendra P.
Published: July 2021

The constancy of the speed of light c is the foundation of most physical theories and is found to be indeed constant from local measurements. Whether or not the same is true at cosmological timescale has been of interest for some time. The measurement of time delay difference in the peaking of the luminosity between two gravitationally lensed images of a type 1a-supernova has recently been proposed to determine if c was different from its current value at the time the images were produced by a lensing galaxy. Since the geometrical time delay and the Shapiro time delay both scale as G/c
3 we show that this method of constraining c is valid only when the potential variation of the gravitational constant G is ignored: c variation is imperceptible when G ∼ c

Detection and Removal of Periodic Noise in Kepler/K2 Photometry with Principal Component Analysis
Authors: Clarke Riley W. , Bianco Federica , Gizis John
Published: July 2021

We present a novel method for detrending systematic noise from time series data using Principal Component Analysis (PCA) in Fast Fourier Transforms. This method is demonstrated on time series data obtained from the inaugural campaign of the Kepler K2 mission, as well as three objects of interest from Campaign 4. Unlike previous detrending techniques that utilize PCA, this method performs the detrending in Fourier space rather than temporal space. The advantage of performing the analysis in frequency space is that the technique is sensitive purely to the periodicity of the unwanted signal and not to its morphological characteristics. This method could improve measurements of low signal-to-noise photometric features by reducing systematics. We also discuss challenges and limitations associated with this technique.
Habitability of Martian Noachian Hydrothermal Systems as Constrained by a Terrestrial Analog on the Colorado Plateau

Volcanic features and impact craters are ubiquitous features on Mars, and hydrothermal systems associated with the production of these features should have been abundant in Mars’s early history. These hydrothermal systems represent potentially habitable environments and are therefore a high priority for continued investigations of the Martian crust. Here we present a Mars analog study where basaltic magma intruded water-bearing sediments to produce a high-temperature (as high as ∼700°C) hydrothermal system, which we use to constrain the potential habitability of similar systems on Mars via mineralogy and geochemistry including S, C, and O isotopic systematics. Our analog site suggests evidence for a habitable environment once the system cooled below 120°C and the potential presence of microbial activity based on the combination of dolomite and C-isotopic systems in the same sample. These findings highlight the importance of future missions to investigate the interface of sediments with magmas and/or late-stage impact melts where microbial life may have taken hold when temperature conditions allowed.

BACKGROUND: Prevalence of soil-transmitted helminth (STH) infections is high in developing countries, especially in school children. STH infections can lead to anemia.

AIM: The aim of the study was to observe the correlation between STH infections and anemia cases in primary school children.

METHODS: Analytical observation with a cross-sectional method was carried out by retrieving data from the health service unit in Talawi. Research samples were primary school children, grouped into STH infected and uninfected groups. The data were analyzed using continuity correction and Fisher’s exact tests.

RESULTS: From 384 research subjects, 35.9% children were infected with STH and 22.5% of them suffered from anemia. The prevalence of STH infections was consisted of 76.8% Trichuris trichiura, 10.9% Ascaris lumbricoides, 0.7% hookworms, and 11.6% had mixed infections. Anemia was significantly correlated to STH infections and the intensity of T. trichiura infection (odds ratio (95% confidence interval) = 4.5 (2.3–8.6) and 3.6 (1.2–10.9) respectively).

CONCLUSION: Anemia was positively correlated with STH infections and the intensity of T. trichiura infection.
The recorded economic costs of alien invasive species in Italy

Whilst the ecological impacts of invasion by alien species have been well documented, little is known of the economic costs incurred. The impacts of invasive alien species on the economy can be wide-ranging, from management costs, to loss of crops, to infrastructure damage. However, details on these cost estimates are still lacking, particularly at national and regional scales. In this study, we use data from the first global assessment of economic costs of invasive alien species (InvaCost), where published economic cost data were systematically gathered from scientific and grey literature. We aimed to describe the economic cost of invasions in Italy, one of the most invaded countries in Europe, with an estimate of more than 3,000 alien species. The overall economic cost of invasions to Italy between 1990 and 2020 was estimated at US$ 819.76 million (EUR€ 704.78 million). This cost was highest within terrestrial habitats, with considerably fewer costs being exclusively associated with aquatic habitats and management methods, highlighting a bias within current literature. There was also a clear indication of informational gaps, with only 15 recorded species with costs. Further, we observed a tendency towards particular taxonomic groups, with insect species accounting for the majority of cost estimates in Italy. Globally, invasion rates are not slowing down and the associated economic impact is thus expected to increase. Therefore, the evaluation and reporting of economic costs need to be improved across taxa, in order to mitigate and efficiently manage the impact of invasions on economies.
