description: Boundary conforming coordinates are commonly used in plasma physics to describe the geometry of toroidal domains, for example, in three-dimensional magnetohydrodynamic equilibrium solvers. The magnetohydrodynamic equilibrium configuration can be approximated with an inverse map, defining nested surfaces of constant magnetic flux. For equilibrium solvers that solve for this inverse map iteratively, the initial guess for the inverse map must be well defined and invertible. Even if magnetic islands are to be included in the representation, boundary conforming coordinates can still be useful, for example to parametrize the interface surfaces in multi-region, relaxed magnetohydrodynamics or as a general-purpose, field-agnostic coordinate system in strongly shaped domains. Given a fixed boundary shape, finding a valid boundary conforming mapping can be challenging, especially for the non-convex boundaries from recent developments in stellarator optimization. In this work, we propose a new algorithm to construct such a mapping, by solving two Dirichlet-Laplace problems via a boundary integral method. We can prove that the generated harmonic map is always smooth and has a smooth inverse. Furthermore, we can find a discrete approximation of the mapping that preserves this property.

Mapping Temperature Offset and assessing the Impact of Disturbance and Elevation in Alpine Forests

Publisher: name: Zenodo
Year: 2022

description: Forest microclimates have the potential to serve as microrefugia for species under climate change. Temperature offset maps can be used to capture the heterogenous microclimate temperature landscape and its temperature buffering capacity. However, amplification of forest disturbance under climate change could impair the temperature buffering capacity of forests. Boosted Regression models based on 150 microclimatic and 16 macroclimatic temperature records, as well as on predictors representing topography and forest structure derived from LiDAR data were used to predict temperature offset for 3 summer months in the Berchtesgaden alpine national park (BGNP). Maps were created for 5 temperature offset metrics, which were compared to a forest disturbance map and a digital elevation model. Furthermore, the relative influence of topography and forest structure was quantified, and the effect of changes in weather conditions on temperature offset was assessed. Model performance was satisfactory explaining between 0.48 to 0.74 % of variance in the relevant models. The results show that temperature offset decreases with elevation, while exhibiting strong differences between forest types. Mean and low temperature offsets increased with successional stage in the submontane and montane area, suggesting an increase in solar radiation after disturbance that leads to microclimatic warming. Forest structure had the highest relative influence in all models, even though it decreased for high offset metrics. In warmer and drier weather conditions, temperature offsets tended to increase in lower elevations and decrease in higher elevations. Pine forests showed particularly low temperature offsets, as well as the strongest decrease during the warmest month, making these habitats most sensitive to impacts of climate change. The offset maps could be compared to existing forest inventories and biodiversity assessments, and has potential uses for various future study projects in BGNP.
A Study of Strain Effects in Ni Alloys

Publisher: name: California Institute of Technology
Year: 1971
Subjects: Electrical Engineering

description: A method for producing uniaxially strained films on an unstrained substrate is described. These films were used to measure the strain sensitivity for γ-phase Ni-Fe and Ni-Co alloys. They were also used to investigate the process of strain relaxation in thin films.

The experimental strain sensitivity was found to be roughly half of the strain sensitivity predicted from bulk material properties for all alloys measured. The strain sensitivity was predicted from bulk magnetoelastic constants by assuming that a film is uniformly strained when its substrate is bent. In the limit of zero thickness, this assumption of a uniform strain is undoubtedly correct. Since no thick-ness dependence was found for films between 64 and 2800 Å, the uniform strain model should apply to all normal thicknesses. The applied strain sensitivity was found to be independent of strain in agreement with the model of uniform strain. All experimental results are consistent with the assumption that thin film elastic constants are roughly half of bulk elastic constants.

A simple model for uniaxial strain relaxation by volume diffusional creep, roughly predicted the dependence of strain upon annealing time and temperature. A method for determining a single activation energy for the complex process of strain relaxation was found. This activation energy (2.4 ev) is in good agreement with the model used. It was concluded that the dominant mechanism for strain relaxation in thin films is volume diffusional creep.

description: We review a subset of experimental results from the heavy-ion collisions at the Large Hadron Collider (LHC) facility at CERN. Excellent consistency is observed across all the experiments at the LHC (at center of mass energy of 2.76 TeV) for the measurements such as charged particle multiplicity density, azimuthal anisotropy coefficients and nuclear modification factor of charged hadrons. Comparison to similar measurements from the Relativistic Heavy Ion Collider (RHIC) at lower energy (center of mass energy of 200 GeV) suggests that system formed at LHC has a higher energy density, larger system size, and lives for a longer time. These measurements are compared to model calculations to obtain physical insights on the properties of matter created at the RHIC and LHC.

description: Постановка проблемы. Идентификация личности является актуальной, социально значимой проблемой. Для установления биологического возраста как первоочередной ступени в рамках судебно-медицинской экспертизы неизвестного лица используются множественные уравнения регрессии, что не всегда обосновано с позиций современных интеллектуальных технологий. Для совершенствования методологического подхода решения данной задачи авторы предлагают использовать методы машинного обучения. В статье представлены результаты проведенного сравнительного анализа применения различных алгоритмов классификаций и дана оценка целесообразности применения их для решения конкретной прикладной задачи судебно-медицинской экспертизы.
Цель работы – анализ возможности использования в судебной медицине методов машинного обучения путем сравнения точности работы наиболее популярных алгоритмов при определении возрастной группы неизвестных (неопознанных) лиц по различным морфометрическим данным.
Результаты. На основании проведенного сравнительного анализа методов машинного обучения, наиболее часто используемых в медицине, выбраны оптимальные для решения задач судебной медицины: деревья решений и их модификация – алгоритм Randomforest (случайный лес), а также многослойные нейронные сети. Сравнительные эксперименты показали, что первые обладают достаточной степенью точности, легко интерпретируемы и просты в настройке, а нейронные сети позволяют достичь наибольшей точности классификации.
Практическая значимость. Полученные результаты могут использоваться как обоснование выбора деревьев решений и нейронных сетей в рамках решения задачи диагностики биологического возраста неизвестного индивидуума с использованием современных информационных интеллектуальных технологий.

description: Постановка проблемы. Основное место в процессе жизнедеятельности биологических объектов принадлежит изменению состояния водной составляющей. Традиционным информационным методом изучения состояния водной среды является спектрометрия. Рассматривая воду как систему, состоящую из двух равновесных фракций (кластеры и свободные молекулы), можно проследить динамику процессов изменения состояния водной среды при различных электромагнитных излучениях (ЭМИ) и температурах. Сложностью изучения структурных молекулярных изменений в водной среде является их нестабильность во времени. Получение информации о состоянии водной среды в различных условиях является основной целью научной и прикладной биологии и медицины.
Цель – изучение механизмов структурных молекулярных электромагнитных изменений различных состояний воды в частотном диапазоне 100…1000 МГц.
Результаты. Исследован электромагнитный отклик кластерных структур воды после воздействия ЭМИ в частотном диапазоне 100…1000 МГц. Описаны полученные различия между откликами на воздействие ЭМИ на кислотную и щелочную составляющие воды. Установлено, что при энергии воздействия на кластеры Е = nћω основным параметром является число квантов «n», определяющих энергетическую реакцию конкретного кластера. Показано, что кластерные перестройки, характеризуемые пиками электромагнитного пропускания (ПЭП), описывают параметрический резонанс. Показано, что эти перестройки по-разному активизируются при воздействии лазерного излучения 635 нм в зависимости от частоты ЭМИ и температуры.
Практическая значимость. Полученные результаты могут использоваться в разработке методик электромагнитного воздействия в практической медицине при диагностике и лечении многих заболеваний.

description: The inverse seesaw mechanism allows the neutrino masses to be generated by new physics at an experimentally accessible scale, even with O(1) Yukawa couplings. In the inverse seesaw scenario, the smallness of neutrino masses is linked to the smallness of a lepton number violating parameter. This parameter may arise radiatively. In this paper, we study the cosmological implications of two contrasting radiative inverse seesaw models, one due to Ma and the other to Law and McDonald. The former features spontaneous, the latter explicit lepton number violation. First, we examine the effect of the lepton-number violating interactions introduced in these models on the baryon asymmetry of the universe. We investigate under what conditions a pre-existing baryon asymmetry does not get washed out. While both models allow a baryon asymmetry to survive only once the temperature has dropped below the mass of their heaviest fields, the Ma model can create the baryon asymmetry through resonant leptogenesis. Then we investigate the viability of the dark matter candidates arising within these models, and explore the prospects for direct detection. We find that the Law/McDonald model allows a simple dark matter scenario similar to the Higgs portal, while in the Ma model the simplest cold dark matter scenario would tend to overclose the universe.

description: We calculate the complete next-to-leading order (NLO) QCD corrections to the $J/ψ+W$ associated production within the factorization formalism of nonrelativistic QCD at the $7 TeV$ LHC. We provide the numerical results for the leading-order (LO), NLO QCD corrected differential cross sections of the $J/ψ$ transverse momentum by adopting the event selection criteria requested by the ATLAS experiment. We find that the differential cross section at the LO is significantly enhanced by the NLO QCD corrections.

Topological data analysis with Bregman divergences

name: Wagner, Hubert
Publisher: name: Journal of Computational Geometry
Year: 2019

description: We show that the framework of topological data analysis can be extended from metrics to Bregman divergences, widening the scope of possible applications. Examples are the Kullback-Leibler divergence, which is commonly used for comparing text and images, and the Itakura-Saito divergence, popular for speech and sound. In particular, we prove that appropriately generalized Cech and Delaunay (alpha) complexes capture the correct homotopy type, namely that of the corresponding union of Bregman balls. Consequently, their filtrations give the correct persistence diagram, namely the one generated by the uniformly growing Bregman balls. Moreover, we show that unlike the metric setting, the filtration of Vietoris-Rips complexes may fail to approximate the persistence diagram. We propose algorithms to compute the thus generalized Cech, Vietoris-Rips and Delaunay complexes, experimentally test their efficiency, and explain their surprisingly good performance by making a connection with discrete Morse theory.

description: Постановка проблемы. Одним из способов реализации обратной связи в протезе является механотактильная стимуляция. В процессе разработки таковой необходимо учесть влияние формы стимула на точность передачи информации.
Цель – экспериментальное сравнение распознаваемости человеком тактильных стимулов разной формы.
Результаты. В качестве стимулов использовались цилиндрические и полусферические элементы, которыми осуществлялось надавливание на кожу. На выборке из семи испытуемых было показано, что для создания тактильного стимула, со-ответствующего порогу восприятия, давящий элемент, имеющий цилиндрическую форму, требует приложения в 2,42 раза большей силы, чем полусферический; разница между надпороговой и пороговой силой воздействия у полусферического давящего элемента в 1,2 раза меньше, чем у цилиндрического. Таким образом, в механотактильных системах форма стимула может влиять на динамический диапазон, а также на энергопотребление, поскольку при худшей распознаваемости стимула требуются более амплитудные воздействия для тактильного раздражения.
Практическая значимость. Результаты этой работы могут быть использованы при разработке систем механотактильной обратной связи в протезах.

description: It has been proposed that the supermassive black hole candidates at the centers of galaxies might be wormholes formed in the early Universe and connecting our Universe with other sister Universes. The analysis of the profile of the relativistic K$α$ iron line is currently the only available approach to probe the spacetime geometry around these objects. In this paper, I compute the expected K$α$ iron line in some wormhole spacetimes and I compare the results with the line produced around Kerr black holes. The line produced in accretion disks around non-rotating or very slow-rotating wormholes is relatively similar to the one expected around Kerr black holes with mid or high value of spin parameter and current observations are still marginally compatible with the possibility that the supermassive black hole candidates in galactic nuclei are these objects. For wormholes with spin parameter $a_* \gtrsim 0.02$, the associated K$α$ iron line is instead quite different from the one produced around Kerr black holes, and their existence may already be excluded.

description: Dozens of hybrids of natural alkaloid evodiamine/rutaecarpine and thieno[2,3-d]pyrimidinones were synthesized in a straightforward method by condensation of substituted 2H-thieno[2,3-d][1, 3]oxazine-2,4(1H)-diones or N-methyl-2H-thieno[2,3-d][1, 3]oxazine-2,4(1H)-dione with 3,4-dihydro-β-carbolines. In vitro cytotoxic assay discovered that compounds 9a, 10e, 11a, 11d, 11f, and 12a could induce antiproliferation against four different types of human cancer cells while compounds 10f and 12e were inactive. Notably, compound 11a displayed potent cell cytotoxicity for human non-small cell lung cancer cells A549, PC-9, human prostate cancer cells PC-3, and human breast cancer cell line MCF-7. Furthermore, compound 11a exhibited strong colony formation inhibition to A549 cells. These results unfold potential anticancer therapeutic applications of hybrids of thieno[2,3-d]pyrimidinones and quinazolinones.

description: Symmetry is at the heart of coding theory. Codes with symmetry, especially cyclic codes, play an essential role in both theory and practical applications of classical error-correcting codes. Here we examine symmetry properties for codeword stabilized (CWS) quantum codes, which is the most general framework for constructing quantum error-correcting codes known to date. A CWS code Q can be represented by a self-dual additive code S and a classical code C, i.,e., Q=(S,C), however this representation is in general not unique. We show that for any CWS code Q with certain permutation symmetry, one can always find a self-dual additive code S with the same permutation symmetry as Q such that Q=(S,C). As many good CWS codes have been found by starting from a chosen S, this ensures that when trying to find CWS codes with certain permutation symmetry, the choice of S with the same symmetry will suffice. A key step for this result is a new canonical representation for CWS codes, which is given in terms of a unique decomposition as union stabilizer codes. For CWS codes, so far mainly the standard form (G,C) has been considered, where G is a graph state. We analyze the symmetry of the corresponding graph of G, which in general cannot possess the same permutation symmetry as Q. We show that it is indeed the case for the toric code on a square lattice with translational symmetry, even if its encoding graph can be chosen to be translational invariant.

description: We revisit particle creation in strong fields, and backreaction on those fields, from an amplitudes perspective. We describe the strong field by an initial coherent state of photons which we explicitly evolve in time, thus going beyond the background field approximation, and then consider observables which quantify the effects of backreaction. We present expressions for the waveform, vacuum persistence probability, and number of produced photons at next-to-leading order, all of which are impacted by backreaction, along with the number and statistics of produced pairs. We find that converting between in-out (amplitude) and in-in (expectation value) expressions requires explicit resummation of an infinite number of disconnected loop diagrams.

description: Asteroids and comets are of strategic importance for science in an effort to understand the formation, evolution and composition of the Solar System. Near-Earth Objects (NEOs) are of particular interest because of their accessibility from Earth, but also because of their speculated wealth of material resources. The exploitation of these resources has long been discussed as a means to lower the cost of future space endeavours. In this paper, we consider the currently known NEO population and define a family of so-called Easily Retrievable Objects (EROs), objects that can be transported from accessible heliocentric orbits into the Earth's neighbourhood at affordable costs. The asteroid retrieval transfers are sought from the continuum of low energy transfers enabled by the dynamics of invariant manifolds; specifically, the retrieval transfers target planar, vertical Lyapunov and halo orbit families associated with the collinear equilibrium points of the Sun-Earth Circular Restricted Three Body problem. The judicious use of these dynamical features provides the best opportunity to find extremely low energy Earth transfers for asteroid material. A catalogue of asteroid retrieval candidates is then presented. Despite the highly incomplete census of very small asteroids, the ERO catalogue can already be populated with 12 different objects retrievable with less than 500 m/s of Δv. Moreover, the approach proposed represents a robust search and ranking methodology for future retrieval candidates that can be automatically applied to the growing survey of NEOs.

description: Dozens of hybrids of natural alkaloid evodiamine/rutaecarpine and thieno[2,3-d]pyrimidinones were synthesized in a straightforward method by condensation of substituted 2H-thieno[2,3-d][1, 3]oxazine-2,4(1H)-diones or N-methyl-2H-thieno[2,3-d][1, 3]oxazine-2,4(1H)-dione with 3,4-dihydro-β-carbolines. In vitro cytotoxic assay discovered that compounds 9a, 10e, 11a, 11d, 11f, and 12a could induce antiproliferation against four different types of human cancer cells while compounds 10f and 12e were inactive. Notably, compound 11a displayed potent cell cytotoxicity for human non-small cell lung cancer cells A549, PC-9, human prostate cancer cells PC-3, and human breast cancer cell line MCF-7. Furthermore, compound 11a exhibited strong colony formation inhibition to A549 cells. These results unfold potential anticancer therapeutic applications of hybrids of thieno[2,3-d]pyrimidinones and quinazolinones.

description: The present study is a systematic review of the scientific literature reporting content, composition and biosynthesis of glucosinolates (GLS), and their derivative compounds in Brassica family. An amended classification of brassica species, varieties and their GLS content, organized for the different plant organs and in uniformed concentration measure unit, is here reported for the first time in a harmonized and comparative manner. In the last years, the studies carried out on the effect of processing on vegetables and the potential benefits for human health has increased rapidly and consistently the knowledge on the topic. Therefore, there was the need for an updated revision of the scientific literature of pre- and post-harvest modifications of GLS content, along with the role of gut microbiota in influencing their bioavailability once they are ingested. After analyzing and standardizing over 100 articles and the related data, the highest GLS content in Brassica, was declared in B. nigra (L.) W. D. J. Koch (201.95 ± 53.36 µmol g−1), followed by B. oleracea Alboglabra group (180.9 ± 70.3 µmol g−1). The authors also conclude that food processing can influence significantly the final content of GLS, considering the most popular methods: boiling, blanching, steaming, the latter can be considered as the most favorable to preserve highest level of GLS and their deriviatives. Therefore, a mild-processing strategic approach for GLS or their derivatives in food is recommended, in order to minimize the loss of actual bioactive impact. Finally, the human gut microbiota is influenced by Brassica-rich diet and can contribute in certain conditions to the increasing of GLS bioavailability but further studies are needed to assess the actual role of microbiomes in the bioavailability of healthy glucosinolate derivatives.

description: Two series of thiazinone and thiosemicarbazone derivatives (1-12) were synthesized using 2,4-diaryl-3-azabicyclo[3.3.1]nonan-9-ones (ABNs) and 3–alkyl–2,6–diarylpiperidin–4–ones as the starting materials. The structures of newly synthesized compounds were established on the basis of FT–IR, NMR spectroscopy and mass spectrometry. From the spectroscopic data, we identified that the cyclization reaction of thioamide with dialkyl acetylenedicarboxylate selectively gives six membered methyl 2-(2-(2,4-disubstituted-3-azabicyclo[3.3.1]nonan-9-ylidene)hydrazinyl)-4-oxo-4H-1,3-thiazine-6-carboxylates (1-6). In order to investigate the antitumor activities of the synthesized compounds, in vitro cytotoxicity studies were carried out using human prostate cancer cell lines. Tested compounds showed good/moderate activities against cancer cell lines and further investigation carried out by live/dead assay.

description: Superconducting resonators provide a convenient way to measure loss tangents of various dielectrics at low temperature. For the purpose of examining the microscopic loss mechanisms in dielectrics, precise measurements of the internal quality factor at different values of energy stored in the resonators are required. Here, we present a consistent method to analyze a LC superconducting resonator coupled to a transmission line. We first derive an approximate expression for the transmission S-parameter $S_{21}$ based on a complete circuit model. In the weak coupling limit, we show that the internal quality factor is reliably determined by fitting the approximate form of $S_{21}$. Since the voltage $V$ of the capacitor of the LC circuit is required to determine the energy stored in the resonator, we next calculate the relation between $V$ and the forward propagating wave voltage $V_{in}^+$. Due to the dependence of the quality factor on voltage, $V$ is not simply proportional to $V_{in}^+$. We find a self-consistent way to determine the relation between $V$ and $V_{in}^+$, which employs only the fitting parameters for $S_{21}$ and a linear scaling factor. We then examine the resonator transmission in the cases of port reflection and impedance mismatch. We find that resonator transmission asymmetry is primarily due to the reflection from discontinuity in transmission lines. We show that our analysis method to extract the internal quality factor is robust in the non-ideal cases above. Finally, we show that the analysis method on LC resonator can be generalize to arbitrary weakly coupled lumped and distributed resonators. The generalization uses a systematic approximation on the response function based on the pole and zero which are the closest to the resonance frequency. This Closest Pole and Zero Method (CPZM) is a valuable tool for analyzing physical measurements of high-Q resonators.

description: A novel series of [2-(2,6-dichlorophenylamino)-phenyl]-acetic acid N`-3-(substituted)-4-thiazolidin-5-ylidenemethyl-hydrazide derivatives has been designed and synthesized. The structures of synthesized compounds were confirmed by their 1H NMR, 13C NMR and LCMS spectroscopic data. Target compounds were screened for their in vitro anticancer activity according to US NCI protocols, in vitro trypanocidal activity toward Trypanosoma brucei brucei (Tbb) and evaluated for anti-inflammatory activity on the carrageenan edema model in rats. Biological screening data led to identification of compounds 3.3 ([2-(2,6-dichloro-phenylamino)-phenyl]-acetic acid N`-(4-oxo-2-thioxo-thiazolidin-5-ylidenemethyl)-hydrazide) and 3.7 ([2-(2,6-dichloro-phenylamino)-phenyl]-acetic acid N`-(4-oxo-2-thioxo-3-(3-trifluoromethylphenyl)thiazolidin-5-ylidenemethyl)-hydrazide) which demonstrated moderate antitumor activity on the non-small-cell lung cancer NCI-H522 and colon cancer HCT-116 cell lines. Several hit compounds (3.2, 3.4) exhibited the promising and significant inhibition growth of the parasites at micromolar concentrations (IC50 values of 4.8 and 7.06 μM, respectively). The synthesized compounds also demonstrated considerable anti-inflammatory effect comparable to the reference non-steroidal anti-inflammatory drugs (NSAIDs) diclofenac sodium or ketorolac tromethamine.
