Abstract
We compare THz emission properties of rectangular, circular, and diabolo spintronic antennas composed of 2 nm Fe and 3 nm Pt layers on MgO substrates. Although the rectangular antenna generated the highest amplitude (∼1.8× improvement), the radiation spectra showed no significant difference. To fully check the effect of antennas, we fabricated diabolo and rectangular antennas with 200 nm Pt layer at the displacement current direction. We observed a 4.2× amplitude improvement using the rectangular antenna and a shift in the bandwidth as well as the peak frequency. These results suggest that spintronic antennas can be designed to be well-suited for specific applications.

Abstract
It has been extremely difficult for nanodiamond composite (NDC) films to be deposited on Ti due to a large thermal expansion coefficient difference. The native oxide layer on Ti is another problem preventing the appropriate adhesion of NDC films and subsequent delamination. In this work, innovative room temperature adhesion of 3 μm NDC films with 54 GPa hardness on Ti substrates was accomplished via a hybrid system of ion etching gun and coaxial arc plasma deposition (CAPD). Ar+ plasma etching is capable to terminate the superficial TiO2 layer and manipulates substrate morphology during CAPD provides instantaneous deposition of NDC films at room temperature.
Pengaruh Variasi Media Pendingin Proses Quenching Terhadap Mikrostruktur dan Sifat Mekanik Baja Hadfield

Manganese steel contains 1,2% C and 12% Mn generally recognized as Hadfield steel. Based on the high composition of C and Mn elements, the main structure of this steel is dominated by an austenite matrix that surrounded the carbide phase on the grain boundary. This structure is usually brittle which leads to improper high-loading conditions. To overcome this problem, the experimental method was carried out by heating Hadfield steel to a temperature of 1000 oC, then followed by a quenching process using cooling media variations namely water and salt bath (20 wt.% NaCl solution). These cooling media variations aim to determine the level of carbide formation which affects the microstructure and mechanical properties. From the test results, it was obtained that Hadfield steel with salt bath (20 wt.% NaCl) quenching variation has significant microstructure transformation which affects enhancement of the value of tensile and yield strength (809,5 and 542,4 MPa), hardness (238 HV), ductility and toughness.

Polystyrene plastic or stryrofoam is very popular to be used as a food packaging container even though Styrofoam has a bad impact on health. In addition, Styrofoam also cannot be biodegraded naturally in the environment so that the use of Styrofoam is also a problem for the environment. One alternative to styrofoam is biodegradable foam (biofoam) made from starch and cellulose. It is safe for health and can be broken down naturally.Cassava peel is rich in starch (carbohydrates) but has low cellulose content. Meanwhile coffee peel is rich in cellulose and minimal in carbohydrates. Both types of waste have the potential to become biodegradable foam raw materials. The addition of synthetic PVA polymer is expected to improve the mechanical quality of biodegradable foam. This study aims to obtain the best formulation for the manufacture of biodegradable foam from cassava starch with the addition of coffee peel cellulose and PVA. The quality of biofoam evaluated includes tensile strength, water absorption, and biodegradability. The best biofoam characteristics were obtained at the addition of 15% fiber and 15% PVA, resulted in water absorption of 28.87%, tensile strength of 2.70 N / mm2 and biodegradability of 93.66% for 30 days.

Published: October 2022

<p>In recent decades, with the placement of LiDAR remote sensing instruments in orbit, we now have global coverage of the bare ground elevation on the Earth, Mars and beyond. Encoded in such planetary LiDAR data are interesting landscape features that promise to further our knowledge of planetary topography. However, discovery of such features comes with 3 major challenges: First, the volume of planetary LiDAR data can be massive, often comprising of hundreds of millions to billions of data points. This calling for analytical algorithms with great efficiency. Second, interesting features can often repeat themselves in multiple scales in local regions, thus it is vital to enable multi-scale feature discovery. Third, planetary LiDAR data can be heterogeneous, and evaluation of the quality of the extracted features can often be hampered by a variety of interfering factors. In response to these challenges, we propose FARMYARD, a generic pipeline for Feature Discovery From Planetary LiDAR Data. To the best of our knowledge, this is the first time such a pipeline has been proposed, which provides a brand new methodology for comparative studies of planetary topography. Specifically, drawing on the parallel computing power of the Graphics Processing Unit (GPU), we propose a novel pseudo-on-pass sweep (POPS) framework for fast and memory-efficient feature extraction for massive planetary LiDAR data, a two-level division scheme for local regions with support for multi-scale features, and a Domain-Shifted Partition (DSP) scheme for feature evaluation that is robust against interfering factors. To showcase the utility of our FARMYARD pipeline, we deploy it to an ongoing real-world research project called PARKER, which seeks to find topographical signatures of life by discovering features that can potentially distinguish between the Earth and alien worlds with no known life activity. We also highlight the efficiency of our POPS framework with experiments on both synthetic and real data, which can be hundreds or even thousands of times faster than its CPU-based counterpart, including an MPI-based multi-core parallel solution.</p>
Konsep Liberalisme Politik John Rawls sebagai Jawaban terhadap Tantangan Masyarakat Plural dan Kritik atasnya
Authors: Gusti Ndegong Madung Otto 
Published: October 2022

This article aims to explore critically John Rawls’ concept of political liberalism which is meant to be a response to the conflict and contestation of ideologies, religions, and other comprehensive doctrines in contemporary plural society. The key question is how the universalized principles of justice can be formulated in the conditionof radical pluralism characterized by contestation of different comprehensive doctrines. In answering this question, John Rawls suggests the concept of overlapping consensus and public reason. While taking accountof the fundamental contribution of John Rawls’ thought in the process of overcoming conflicts in a plural society, this essay discusses further some weaknesses of Rawls’ concept of political liberalism, and at thesame time proposes a new model of political philosophy which provides room for fundamental dissent. This new political philosophy can be called liberal fundamentalism. Fundamentalism basically expressesitself in public sphere in the form of liberality. This essay argues that liberal fundamentalism can create a social condition where fundamental moral differences are accepted, respected, and recognized.
Abstrak
Tulisan ini bertujuan membahas secara kritis konsep liberalisme politik John Rawls sebagai jawaban atas konfl ik dan kontestasi pandangan hidup atau doktrin komprehensif yang menandai masyarakat kontemporer yang plural. Pertanyaan pokok yang dibahas dalam tulisan ini ialah, bagaimana prinsip-prinsip keadilan yang berlakuumum dapat dirumuskan dalam kondisi factum pluralisme atau pertarungan doktrin-doktrin komprehensif tersebut. Untuk menjawab pertanyaan ini, Rawls menganjurkan dua konsep yakni overlapping consensus dan public reason. Tanpa mengabaikan kontribusi Rawls dalam menyelesaikan konflik dalam masyarakat plural, tulisan ini lebih jauh menunjukkan kelemahan konsep liberalisme politik John Rawls, dan menganjurkan sebuah filsafat politik baru yang harus memberi ruang bagi disensus-disensus fundamental. Filsafat politik baru itu dapat dinamakan posisi fundamentalisme liberal. Sebuah fundamentalisme yang mengungkapkan diri di ruang publik dalam bentuk liberalitas. Artinya, kondisi sebuah masyarakat yang memberi ruang bagi pertentangan-pertentangan etis fundamental, namun dihadapi dengan sikap pengakuan dan penghargaan atas perbedaan fundamental tersebut.

В работе рассмотрены основные параметры модели Karagozian & Case Concrete для высокоскоростного деформирования бетона. Представлен расчет каркасного здания из железобетона на прогрессирующее разрушение. Выполнены исследования в четырех различных постановках от линейного статического подхода на основе стержневой аналогии для каркаса здания до полностью нелинейного динамического расчета на основе метода конечных элементов. Были определены предельно допустимые нагрузки, максимальные перемещения в элементах каркаса, максимальные напряжения в арматуре. Сделаны выводы об эффективности различных подходов.
Explosive devices are getting smaller and more powerful. In this regard, of considerable interest for the mechanics of structures and their elements is the solution of the problem of determining the stress-strain state of buildings and structures under the action of short-term dynamic effects in the form of external explosive effects and preventing their consequences in the form of progressive destruction. The paper considers the main parameters of the Karagozian & Case Concrete model for high-speed concrete deformation. The article considers the calculation of a frame building made of reinforced concrete for progressive destruction. The studies were carried out in four different formulations from a linear static approach based on a rod analogy for a building frame to a fully nonlinear dynamic calculation based on the finite element method. Based on the results obtained, the maximum allowable loads, maximum displacements in the frame elements, and maximum stresses in the reinforcement were determined. Conclusions are drawn about the effectiveness of various approaches.

Предложена схема плоской статически определимой плоской рамы с прямолинейными верхним и нижним поясами. Рама крепится на две опоры: подвижную и неподвижную. Анализируются зависимости прогиба фермы от количества панелей и вариантов нагрузки (нагружение по верхнему, а также нижнему поясам; сосредоточенная узловая нагрузка в середине пролета). На основании расчетов в символьной форме получены формулы для усилий в наиболее растянутых или сжатых стержнях. Для примера приведено распределение усилий по стержням конструкции. Чтобы получить аналитическое решение прогиба конструкции и изменения ее подвижной опоры, применяется метод обобщения частных решений на случай произвольного числа панелей. Прогиб рассчитан по формуле Максвелла-Мора. Построение системы уравнений равновесия узлов и преобразование результатов выполняются в системе компьютерной математики Maple.
A scheme of a planar statically definable planar truss with rectilinear upper and lower belts is proposed. The truss is attached by two supports: one movable, the other fixed. The dependences of the deflection of the truss on the number of panels and load options (loading along the upper and lower belts; concentrated nodal load in the middle of the span) are analyzed. Based on calculations in symbolic form, formulas for the forces in the most stretched or compressed rods are obtained. For example, the distribution of forces on the rods of the structure is given. In order to obtain an analytical solution of the deflection of the structure and the change of its movable support, a method of generalization of partial solutions for the case of an arbitrary number of panels is used. The deflection is calculated according to the Maxwell-Mohr formula. The construction of a system of node equilibrium equations and the transformation of the results are performed in the Maple computer mathematics system.
