Published: December 2023

Two-dimensional (2D) materials, especially the materials that have intrinsic ferromagnetism (FM), have attracted considerable attention due to their ultraclean interface, controllable stacking order, good flexibility, and other excellent characteristics. However, the low Curie temperature (T
C
) has limited their practical applications in spintronic devices. Here, we present an approach to enhance the ferromagnetism of the monolayer CrI
3
by adsorbing the transition metal atoms (Fe, Co, and Ni) through the first-principles calculation. Interestingly, the Ni-adsorption of monolayer CrI
3
has improved the T
C
to 167 K and introduced the half-metallic feature with a large energy gap of 1.9 eV, which means a high spin polarization rate close to 100%. We further calculate the magnetic tunnel junction formed by the AB stacking bilayer Ni-adsorbed CrI
3
, which has layer number-dependent magnetic ordering temperature and FM interlayer exchange interaction, by combining density functional theory and the Keldysh nonequilibrium Green’s function. The transport properties calculation results show that the tunnel magnetoresistance (TMR) of this device can reach a large value of 3.94 × 10
4
% due to the half-metallicity induced large spin polarization. The enhanced T
C
, half-metallicity, and large TMR in magnetic tunnel junctions imply that 2D Ni-adsorbed CrI
3
has great potential in practical spintronic applications.

The Moon is exposed to a variety of complex space environments during its 29.5-d orbiting around Earth, of which one-quarter in Earth’s magnetosphere. The collection of particles in Earth’s magnetosphere is called Earth wind, which consists of the solar wind particles entering into the magnetosphere and the ions upflowing from the ionosphere and the upper atmosphere into the magnetosphere. The interaction between Earth wind and the Moon provides insights into understanding the evolution of the whole Earth–Moon system and other planet–moon systems such as Mars, Jupiter, Saturn, and their satellites. The key scientific questions on the Earth wind and the Moon are reviewed and summarized. Finally, the several unaddressed issues and the possible resolution in the Earth wind–Moon interactions are discussed.

Published: December 2023

Time-resolved transient absorption (TA) spectroscopy measurement technology provides detailed information into the ultrafast dynamics by tracking the transitions and deactivation processes of the excited-state carriers, which holds vast potential for investigating processes related to the luminescence and nonradiative recombination of materials. Pressure is considered a potent tool for tuning the carrier dynamic behaviors. The combination of high-pressure experimental technology and time-resolved TA spectroscopy measurement technology enables researchers to reveal the inherent relation between the structure and optical properties of materials, which is crucial for optimizing material performance and applications in the field of optoelectronics. In this review, the principles and the theoretical foundations of high-pressure time-resolved TA spectroscopy measurement technology will be introduced, and the research advancements in ultrafast dynamics processes of materials under high pressure will be summarized and discussed. In addition, we will expound on the future prospects of time-resolved TA spectroscopy measurement technology to detect the ultrafast dynamic behaviors of materials and complexes under the coregulation of temperature and pressure.

Quantum interference occurs frequently in the interaction of laser radiation with materials, leading to a series of fascinating effects such as lasing without inversion, electromagnetically induced transparency, Fano resonance, etc. Such quantum interference effects are mostly enabled by single-photon resonance with transitions in the matter, regardless of how many optical frequencies are involved. Here, we report on quantum interference driven by multiple photons in the emission spectroscopy of nitrogen ions that are resonantly pumped by ultrafast infrared laser pulses. In the spectral domain, Fano resonance is observed in the emission spectrum, where a laser-assisted dynamic Stark effect creates the continuum. In the time domain, the fast-evolving emission is measured, revealing the nature of free-induction decay arising from quantum radiation and molecular cooperativity. These findings clarify the mechanism of coherent emission of nitrogen ions pumped with mid-infrared pump laser and are found to be universal. The present work opens a route to explore the important role of quantum interference during the interaction of intense laser pulses with materials near multiple photon resonance.
Comparação das dimensões avaliativas das políticas públicas brasileiras e holandesas
Authors: Camargo Arthur Mesquita
Published: December 2023

O processo avaliativo das políticas públicas se desenvolveu na medida em que os modelos conceituais de gestão pública foram se aperfeiçoando. Nesta seara, o modelo avaliativo Neerlandês se destaca. Assim, o objetivo geral do artigo é comparar as dimensões avaliativas das políticas públicas brasileiras com as dimensões holandesas. Para alcançar o objetivo, esta pesquisa caracteriza-se como de natureza, prioritariamente, qualitativa, bibliográfica e descritiva. Após as análises devidas, concluiu-se que o campo conceitual dos critérios avaliativos do modelo holandês é mais sofisticado e complexo do que o brasileiro. Além disso, observa-se que, enquanto no modelo pátrio, prioriza-se a análise pela métrica objetiva, no modelo neerlandês, opta-se por uma métrica subjetiva. Por fim, inferiu-se que os critérios de desempenho das políticas públicas neerlandesas possuem um viés teleológico, enquanto que no modelo nacional, os critérios focam em um nível axiológico-econômico.

O tamanduá-mirim (Tamandua tetradactyla) é um animal de hábitos solitários, com atividade em períodos crepusculares e noturnos e se alimenta de insetos sociais. Suas principais características anatômicas são focinho alongado, ausência de dentes, língua vermiforme e grandes garras. Os filhotes são cuidados por suas mães até completarem um ano de idade. O manejo de filhotes de tamanduá-mirim em cativeiro é um desafio pela heterogeneidade de informações acerca de formulações de dietas que atendam às exigências nutricionais desses animais. Ademais, o desmame é um desafio pelo íntimo contato prolongado da prole com sua mãe. O presente trabalho relata as formulações de sucedâneos utilizadas para alimentação do animal recebido no Centro de Biodiversidade da Usipa (CEBUS) em Ipatinga-MG para cuidados parentais, bem como a estratégia de desmame utilizando ovos artificiais como comedouros.

COVID–19 caused schools and universities to change their regular program to online learning. Online learning requires the student to be agile and engaged in the learning process. This paper investigated the impact of goal orientation, openness to experience, and psychological safety toward learning agility on university students. This research used PLS–SEM to analyze the relationships among learning agility constructs. The author conducted quantitative research by developing an online survey using questionnaires from the previously widely used and well–validated instrument. The participants of this study are 206 industrial engineering students of Telkom University, Indonesia. The instrument was fulfilled to what extent the participant agreed with the statement using a six–point Likert scale. A significant relationship was found between learning agility factors: goal orientation, openness to experience, and psychological safety toward learning agility. It was found that goal orientation has a large effect size on learning agility. Thus, it played a central role in the model. Future studies should be conducted with a larger sample with several individual attributes. It may determine whether individual attributes predict difference variation of learning agility.

Laboratoire SF pour humains prolongés : leurre ou détectande ?
Authors: Casta Isabelle Rachel
Published: December 2023

Les enjeux sériels épousent étroitement les grandes interrogations anthropologiques qu’une société se pose… ou est sur le point de se poser; ici se déploie « l’infinie possibilité des possibles », et nous verrons que peu à peu monte en puissance la thématique de l’humain prolongé, souvent sous l’angle d’un transhumanisme devenu fou. Ancrer la thématique de l’augmentation technologique dans l’imaginaire sexuel permet de focaliser immédiatement sur la fantasmatique intime de chaque lecteur/spectateur ; ce motif « situé » singularise aussi le sujet, voué pourtant à la stéréotypie du produit de genre, post-fordiste mais nécessairement soumis à des schémas identifiables. Le dissensus entre désirabilité obscure du processus et horreur des idéologies sous-jacentes formera donc la trame de ce propos ; la coloration dystopique affecte de fait l’essentiel du dispositif, mais sans que soit absente une forme de fascination honteuse pour cette « immortalité » technologique, ou même épistémocratique (voir note 3), que la science semble promettre — aux plus aisés en tout cas.

Analisis Banjir Menggunakan Program HEC-RAS 5.0.7
Authors: Sudirman Sudirman
Published: December 2023

Penelitian ini bertujuan untuk mengetahui debit banjir dan potensi banjir berdasarkan rencana kala ulang tahunan di sekitar Sungai Amassangan. Dalam penelitian ini luas area cakupan banjir dibatasi pada bagian hilir Sungai Amassangan. Program HAC-RAS digunakan untuk menunjukkan debit banjir rencana tahunan pada setiap cross section. Hasil penelitian menunjukkan bahwa berdasarkan perhitungan debit banjir kala ulang tahunan, sungai Amassangan mengalami peningkatan debit banjir dari tahun ke tahun. Lokasi yang sangat berpotensi terendam banjir adalah pada STA 300 – STA 500 dimana palung sungai semakin naik akibat sedimentasi, sehingga aliran air sungai berpotensi untuk meluap ke pinggiran sungai dan menggenangi pemukiman warga di sekitarnya ketika intensitas curah hujan tinggi. Upaya penanggulangan banjir yang dapat di lakukan oleh pemerintah daerah adalah dengan ‘normalisasi’ pada palung sungai dan pinggiran sungai untuk mengoptimalkan fungsi sungai di sepanjang ruas sungai pada bagian hilir
This study aims to determine the flood discharge and flood potential based on the annual return period plan around the Amassangan River. In this study the flood coverage area is limited to the lower reaches of the Amassangan River. The HAC-RAS program is used to show the annual planned flood discharge for each cross section. The results showed that based on the calculation of the annual return flood discharge, the Amassangan river experienced an increase in flood discharge from year to year. Locations that have the potential to be flooded are at STA 300 – STA 500 where the riverbed is rising due to sedimentation, so that the flow of river water has the potential to overflow onto the banks of the river and inundate nearby residents' settlements when the intensity of rainfall is high. Flood control efforts that can be carried out by local governments are by 'normalizing' the riverbeds and riverbanks to optimize the function of the river along the river sections in the downstream

Air lindi di Tempat Pembuangan Akhir (TPA) sangat mempengaruhi kualitas air dilingkungan sekitar TPA. Penelitian ini dilakukan untuk menganalisis kualitas air parit di sekitar TPA Rasau Jaya Kabupaten Kubu Raya. Parameter uji fisika yang diteliti yaitu suhu, TDS, pH, warna dan kekeruhan air. Hasil pengukuran parameter fisika kemudian dibandingkan dengan standar kelayakan baku mutu air bersih berdasarkan Peraturan Menteri Kesehatan (Permenkes) RI Nomor 32 Tahun 2017. Hasil pengukuran parameter fisika air parit di lokasi penelitian diperoleh nilai rata-rata suhu 31°C, nilai rata-rata TDS 25,4 mg/l, nilai rata-rata pH 3,5, nilai rata-rata warna 837,7 TCU, nilai rata-rata kekeruhan 33,6 NTU. Dua dari lima parameter yang dikaji (suhu, dan TDS) memenuhi standar mutu air bersih sedangkan tiga parameter lainnya (kekeruhan, warna, dan pH) tidak memenuhi standar mutu air bersih. Berdasarkan hasil penelitian tersebut air parit di sekitar TPA tidak dianjurkan digunakan sebagai air bersih untuk masyarakat sekitar TPA
