Extreme mechanical metamaterials with independently adjustable elastic modulus and mass density
Authors: Chen Xing , Cai Li , Wen Jihong
Published: February 2022

The mechanical properties of artificially periodic structures are closely related to the geometric dimensions of the structures. In this letter, we derive analytical expressions for the equivalent elastic parameters of a hexagonal cellular structure with additional counterweight mass blocks, and the accuracy of these analytical expressions is verified by numerical results. By analyzing the analytical expressions, we rigorously demonstrate an approximate decoupling relationship between the elastic modulus and mass density. Finally, we creatively propose a structure that can simultaneously achieve perfect decoupling of elastic modulus and mass density as well as flexible adjustment of material parameters in an ultra-wide range.

Published: February 2022

The group of plants known as giant hogweeds: , and are widely recognized as dangerous alien species in Europe. We have analyzed the climatic conditions on the northern boundary of the secondary range of giant hogweeds group species in Northern Europe. The northernmost areas of growth of H. persicum are localized in the coastal regions of the northern and central parts of the Scandinavian Peninsula (up to 71° NL). Within Fennoscandia, the plants and were found up to 69° NL. The natural gradient of climatic parameters within the subarctic and temperate zones in Northern Europe allowed us to assess the ranges of climatic conditions required for the plants in this territory. We have found that the minimum sum of active temperatures values required for these alien plants are >1150 °С (for temperatures above 5 °C) and >450 °С (for temperatures above 10 °C). The heat resource exceeding this level ensures successful growth, development and reproduction of giant hogweeds group species in the climatic conditions of Subarctic Europe. The presence of stable snow cover on the territories with very low air temperatures during winter period prevents buds and seedlings cold damage. Climatic indices calculated as ratio of air temperature and snow depth or winter precipitation can serve as markers reflecting climatic constraints for the expansion of alien giant hogweeds group species in north direction. The main climatic parameters limiting the distribution of these species in Northern Europe are: insufficient sum of active temperatures, seasonal freezing of soils to temperatures critical for wintering organs of plants, late spring and early autumn frosts.

Authors: Wijanarko Dwi Seno
Published: February 2022

A criminal act committed by a person does not eliminate his human dignity, so that his position as a prisoner does not prevent him from getting guaranteed protection and fulfillment of human rights. This provision then animates the existence of a correctional system with a set of accompanying legal instruments, including a coaching system which is embodied in the form of an assimilation program. As part of the prisoner development system, the implementation of assimilation has faced challenges during the COVID-19 pandemic. Departing from the description above, the researcher intends to conduct research related to the implementation of assimilation during the COVID-19 pandemic by placing the research locus in Cipinang Class I Prison. The objectives to be achieved in this research are: 1) Knowing the process of providing assimilation for prisoners in Cipinang Class I Correctional Institution; 2) Knowing the impact resulting from the provision of assimilation for prisoners in the Cipinang Class I Correctional Institution. The type of research used in this study is empirical legal research which bases research on findings in the field, so the approach used in this research is a sociological juridical approach. The results of this study are first, the implementation of assimilation in Cipinang Class 1 Prison is based on the Regulation of the Minister of Law and Human Rights of the Republic of Indonesia Number 10 of 2020. Based on this legal source, Cipinang Class 1 Prison has given as many as 533 assimilation rights to prisoners.

Volkswagen's Bad Decisions & Harmful Emissions: How Poor Process Corrupted Codetermination in Germany's Dual Board Structure
Authors: Sharpe Nicola
Published: February 2022

This Article directly challenges the often argued proposition that Germany's two-tier board of directors is superior to America’s single-tier board structure. It argues that regardless of structure, any decision-making body that lacks effective decision-making processes is at significant risk of failure, scandal, and ineffectiveness. Legal scholars and policymakers have largely ignored the connection between decision-making processes and the efficacy of corporate leadership. The Article is the first to examine this underexplored relationship in the context of the German dual-board.

Volkswagen’s 2015 emissions scandal provides a vehicle to critically assess the relationship between Germany’s two-tiered board and an effective decision-making process. This Article argues that the structure of Volkwagen’s dual board did not automatically result in an effective decision-making processes. Additionally, an effective decision-making process—the attributes of which can be found in organizational behavior theory—is essential to helping German boards accomplish their legislative mandate. Moreover, it is essential to helping the boards of transnational corporations, which have a wide range of structural variations, effectively govern the organizations for whom they work.

In sum, Volkswagen and other German corporations may follow the structural requirements of German corporate law, but without effective processes, German directors are likely to fail in their monitoring and supervisory roles. Without effective processes, directors are watchers asleep at their post, uninformed, dormant, and ineffective in preventing gross failures of corporate integrity. Unless German boards adopt and implement a Process-Oriented Approach, the Volkswagen emission scandal will simply be another mark on a timeline for a century plagued by corporate failure.

Published: February 2022

Dold sequences constitute an important class of integer sequences that play an important role in combinatorics, number theory, topology and dynamical systems. We generalize the notion of Dold sequence for the case of partially ordered sets and describe their properties. In particular we give two alternative descriptions of generalized Dold sequences: by some class of elementary sequences as well as by different generalized arithmetical functions, both defined on a partially ordered set. We also define vector Dold sequences and show their combinatorial interpretation in terms of periodic points.

File replaced 2022–02–24: Erroneous stratigraphic levels in figures 8, 9, 10 and 11 of the original publication are now correct Heat storage in the Danish subsurface is gaining increasing interest for optimiz-ing the use of energy resources, but no deep heat storage facilities have yet been established. As an analogue we study the Gassum Formation in the Stenlille structure that is presently used for gas storage. This allows us to discuss geological and technical characteristics of an aquifer relevant for heat storage in Denmark. We develop a 3D model for a high-temperature aquifer thermal energy storage sys-tem using analysis of geological core data, sedimentological description, geophysi-cal data including well logs and seismic lines, as well as a finite difference model to calculate the recovery efficiency, heat storage capacity and thermal breakthrough time. Based on geostatistical methods we made three realisations and found similar results for the three cases. In accordance with results from published simplified models we found a high recovery efficiency of 70% after 4 years and 69% after 20 years, a high heat storage capacity of 1.8×1018 J, and a long thermal breakthrough time of 66–77 years. These results reflect the excellent reservoir properties of the Gassum Formation in Stenlille, characterised by a uniformly layered sand/shale sedimentology, a high average porosity of 25% and a high permeability of 1000 to 10 000 mD of sandstone intervals.
Investigation of a memory effect in a Au/(Ti–Cu)Ox-gradient thin film/TiAlV structure
Authors: Wojcieszak Damian , Domaradzki Jarosław , Mazur Michał , Kotwica Tomasz , Kaczmarek Danuta
Published: February 2022

This paper presents the results of the analysis of resistive switching properties observed in a Au/(Ti–Cu)Ox/TiAlV structure with a gradient distribution of Cu and Ti along the (Ti–Cu)Ox thin film thickness. Thin films were prepared via multisource reactive magnetron co-sputtering. The programmed profile of the pulse width modulation coefficient during sputtering of the Cu target allowed us to obtain the designed gradient U-shape profile of the Cu concentration in the deposited thin film. Electrical measurements of the Au/(Ti–Cu)Ox/TiAlV structure showed the presence of nonpinched hysteresis loops in the voltage–current plane testifying a resistive switching behavior. Results of optical, X-ray, and ultraviolet photoelectron spectroscopy measurements allowed us to elaborate the scheme of the bandgap alignment of the prepared thin films with respect to the Au and TiAlV electrical contacts. Detailed structure and elemental profile investigations allowed us to conclude about the possible mechanism for the observed resistive switching mechanism.

Participants not Observers: Involving Beneficiaries as Co-assessors in Performance Analysis
Authors: Campbell David , Lambright Kristina
Published: February 2022

This commentary addresses the limited attention researchers and practitioners have given to the role service beneficiaries can and do play in performance analysis in health and human service organizations. We present a six-element framework for understanding that role at the individual, program and system level. The framework contrasts approaches that treat beneficiaries as passive versus active participants in performance analysis. We apply the framework to an imagined disability services organization. Future research should assess beneficiary engagement in performance analysis more systematically, including case studies, surveys of practice, and assessments of the effectiveness of these different approaches.
Practice as Lived Experience: The Missing Link in Public Administration Research
Authors: Elias Maria
Published: February 2022

As public administration and management are increasingly preoccupied with gaining status and legitimacy on the basis of scientific rigor, researchers seem to forget that the field they study is, above all, a practice. Practice questions concern how administrators interpret and act upon a situation, considering social norms and institutional notions that are shared. The relative merits of various modes of research is a long-standing issue in public administration, going back to the Simon-Waldo debate, but despite numerous arguments supporting the necessity of interpretive research approaches, the field has grown increasingly impervious to them. Hence, the need at this point for a wake-up call. This paper retrieves recent developments in interpretive research and makes a case for it in order to tackle our current challenging times, including heightened health risks during the Covid-19 pandemic to political upheaval and economic turmoil.

Авторами поведен анализ современного состояния управления экологическими рисками в нефтегазовой сфере Республики Казахстан. Установлено, что в настоящее время не существует полного определения понятия «экологический риск» и отсутствует единая методика проведения оценки экологического риска. Рассмотрены возможные экологические риски, возникающие при разработке месторождения, добыче сырья, транспортировке и др. Выяснено, что масштабное негативное воздействие происходит при авариях на объектах. В таких ситуациях важна роль законодательных и нормативных документов, которые должны содержать гарантии и критерии недопущения чрезвычайных ситуаций, а в случае критического положения предусматривать действенные меры выхода из них с минимизацией возможных потерь. Авторами отмечено, что вопросы экологической безопасности требуют скорейшего освоения и нормативно-законодательного оформления. Международный и казахстанский опыт в области анализа, оценки и управления экологическими рисками убедительно показывает, что с каждым годом решение таких задач становится все более актуальным не только для общества в целом, но и для отдельных организаций, являющихся объектами недропользования.

Measuring Chemical Likeness of Stars with Relevant Scaled Component Analysis

Published: February 2022

Identification of chemically similar stars using elemental abundances is core to many pursuits within Galactic archeology. However, measuring the chemical likeness of stars using abundances directly is limited by systematic imprints of imperfect synthetic spectra in abundance derivation. We present a novel data-driven model that is capable of identifying chemically similar stars from spectra alone. We call this relevant scaled component analysis (RSCA). RSCA finds a mapping from stellar spectra to a representation that optimizes recovery of known open clusters. By design, RSCA amplifies factors of chemical abundance variation and minimizes those of nonchemical parameters, such as instrument systematics. The resultant representation of stellar spectra can therefore be used for precise measurements of chemical similarity between stars. We validate RSCA using 185 cluster stars in 22 open clusters in the Apache Point Observatory Galactic Evolution Experiment survey. We quantify our performance in measuring chemical similarity using a reference set of 151,145 field stars. We find that our representation identifies known stellar siblings more effectively than stellar-abundance measurements. Using RSCA, 1.8% of pairs of field stars are as similar as birth siblings, compared to 2.3% when using stellar-abundance labels. We find that almost all of the information within spectra leveraged by RSCA fits into a two-dimensional basis, which we link to [Fe/H] and α-element abundances. We conclude that chemical tagging of stars to their birth clusters remains prohibitive. However, using the spectra has noticeable gain, and our approach is poised to benefit from larger data sets and improved algorithm designs.

Plasma jets are ubiquitous in space. In geospace, jets can be generated by magnetic reconnection. These reconnection jets, typically at fluid scale, brake in the near-Earth region, dissipate their energies, and drive plasma dynamics at kinetic scales, generating field-aligned currents that are crucial to magnetospheric dynamics. Understanding of the cross-scale dynamics is fundamentally important, but observation of coupling among phenomena at various scales is highly challenging. Here we report, using unprecedentedly high-cadence data from NASA's Magnetospheric Multiscale Mission, the first observation of cross-scale dynamics driven by jet braking in geospace. We find that jet braking causes MHD-scale distortion of magnetic field lines and development of an ion-scale jet front that hosts strong Hall electric fields. Parallel electric fields arising from the ion-scale Hall potential generate intense electron-scale field-aligned currents, which drive strong Debye-scale turbulence. Debye-scale waves conversely limit intensity of the field-aligned currents, thereby coupling back to the large-scale dynamics. Our study can help in understanding how energy deposited in large-scale structures is transferred into small-scale structures in space.

We have discovered a new X-ray-emitting compact binary that is the likely counterpart to the unassociated Fermi-LAT GeV γ-ray source 4FGL J1120.0–2204, the second brightest Fermi source that still remains formally unidentified. Using optical spectroscopy with the SOAR telescope, we have identified a warm (T
eff ∼ 8500 K) companion in a 15.1 hr orbit around an unseen primary, which is likely a yet-undiscovered millisecond pulsar. A precise Gaia parallax shows the binary is nearby, at a distance of only ∼820 pc. Unlike the typical “spider” or white dwarf secondaries in short-period millisecond pulsar binaries, our observations suggest the ∼0.17 M
⊙ companion is in an intermediate stage, contracting on the way to becoming an extremely low-mass helium white dwarf. Although the companion is apparently unique among confirmed or candidate millisecond pulsar binaries, we use binary evolution models to show that in ∼2 Gyr, the properties of the binary will match those of several millisecond pulsar–white dwarf binaries with very short (<1 day) orbital periods. This makes 4FGL J1120.0–2204 the first system discovered in the penultimate phase of the millisecond pulsar recycling process.
Weak Seasonality on Temperate Exoplanets around Low-mass Stars
Authors: Tan Xianyu
Published: February 2022

Planets with nonzero obliquity and/or orbital eccentricity experience seasonal variations of stellar irradiation at local latitudes. The extent of the atmospheric response can be crudely estimated by the ratio of the orbital timescale to the atmospheric radiative timescale. Given a set of atmospheric parameters, we show that this ratio depends mostly on the stellar properties and is independent of orbital distance and planetary equilibrium temperature. For Jupiter-like atmospheres, this ratio is ≪1 for planets around very low mass M dwarfs and ≳1 when the stellar mass is greater than about 0.6 solar mass. Complications can arise from various factors, including varying atmospheric metallicity, clouds, and atmospheric dynamics. Given the eccentricity and obliquity, the seasonal response is expected to be systematically weaker for gaseous exoplanets around low-mass stars and stronger for those around more massive stars. The amplitude and phase lag of atmospheric seasonal variations as a function of host stellar mass are quantified by idealized analytic models. At the infrared emission level in the photosphere, the relative amplitudes of thermal flux and temperature perturbations are negligible, and their phase lags are closed to −90° for Jupiter-like planets around very low mass stars. The relative amplitudes and phase lags increase gradually with increasing stellar mass. With a particular stellar mass, the relative amplitude and phase lag decrease from low- to high-infrared optical depth. We also present numerical calculations for a better illustration of the seasonal behaviors. Last, we discuss implications for the atmospheric circulation and future atmospheric characterization of exoplanets in systems with different stellar masses.

BACKGROUND: In SLE patients, repeated antigen stimulations induce a progressive reduction in CD28 expression on the surface of T cells and the chronic inflammation condition. Mango’s mistletoe is a parasitic plant that has anti-inflammation, antiproliferation, and immunomodulatory activities.

AIM: This study aimed to investigate the effect of mango’s mistletoe leaves extract (MLE) in inhibiting anti-dsDNA antibodies and ameliorating the percentages of CD8+CD28− and CD4+CD28− T cells in a pristane-induced lupus mice model.

METHODS: Lupus induction was undertaken by an injection of pristane 0.5 ml intraperitoneally in 6–8-week-old female balb/c mice. Mice with lupus signs were grouped randomly into the treatment groups which received MLE at doses of 150, 300, and 600 mg/kgbw/d for 28 days, respectively, and the positive control group without MLE. On day 29, anti-dsDNA antibody levels were analyzed using an ELISA. One of the immunosenescence markers (CD28− T cells) was investigated using a flow cytometer. ANOVA test was used for statistical analysis.

RESULTS: The mango’s mistletoe leaves extract (MLE) significantly decreased the number of anti-dsDNA antibodies (*p < 0.05), the percentages of CD8+CD28− T cells (*p < 0.05) and CD4+CD28− T cells (*p < 0.05).

CONCLUSION: We resume that the mango’s mistletoe leaves can ameliorate lupus by inhibiting anti-dsDNA antibody production and the percentages of CD8+CD28− and CD4+CD28− T cells.
