Authors: Suryanarayana M. V.
Published: December 2023

Isotope separation of 203Tl through pulsed laser optical pumping into the 6s26p2P3/2∘ meta-stable state, followed by pulsed laser ionization, has been theoretically studied through density matrix formalism. The efficiency of the isotope separation process has been compared with the cw laser optical pumping followed by pulsed laser photoionization reported earlier. The effect of peak power density, bandwidth and number density of atoms on the degree of enrichment and the production rate has been systematically studied. The optimum parameters for the efficient laser isotope separation 203Tl have been derived. It has been shown that using this method, it is possible to produce about 1.5 kg/y of  203Tl isotope enriched to 90%.

Authors: Nadinov Issatay , Kovalenko Oleksandr , Rehspringer Jean-Luc , Mager Loïc
Published: December 2023

We utilized a metal propionate solution to prepare polycrystalline bismuth-substituted yttrium iron garnets through the metal-organic decomposition process. After conducting thorough optimization, we successfully synthesized a garnet that exhibited a high magneto-optic response directly at the end of an optical fiber. A notable achievement of our work lies in the ability to restrict the size and position of the garnet to match the dimensions of the fiber's core. The functionalized fiber was integrated into a magneto-optical sensor setup, offering the flexibility to operate either in the Faraday rotation or magnetic circular dichroism mode.
Towards rapid colorimetric detection of extracellular vesicles using optofluidics-enhanced color-changing optical metasurface
Authors: Hong Chuchuan , Hong Ikjun , Yang Sen , Ndukaife Justus C.
Published: December 2023

Efficient transportation and delivery of analytes to the surface of optical sensors are crucial for overcoming limitations in diffusion-limited transport and analyte sensing. In this study, we propose a novel approach that combines metasurface optics with optofluidics-enabled active transport of extracellular vesicles (EVs). By leveraging this combination, we show that we can rapidly capture EVs and detect their adsorption through a color change generated by a specially designed optical metasurface that produces structural colors. Our results demonstrate that the integration of optofluidics and metasurface optics enables spectrometer-less and label-free colorimetric read-out for EV concentrations as low as 107 EVs/ml, achieved within a short incubation time of two minutes.
Fourier metasurface cloaking: unidirectional cloaking of electrically large cylinder under oblique incidence
Authors: Zhang Yi , Fan Haiyan , Zhang Yujie , Ran Lixin , Ye Dexin , Chen Xudong
Published: December 2023

The existence of a non-electrically-small scatterer adjacent to the source can severely distort the radiation and lead to a poor electromagnetic compatibility. In this work, we use a conducting hollow cylinder to shield a cylindrical scatterer. The cylinder is shelled with a single dielectric layer enclosed by an electromagnetic metasurface. The relationship between the scattering field and the surface impedance is derived analytically. By optimizing the Fourier expansion coefficients of the surface impedance distribution along ϕ-dimension, the scattering cross-section can be effectively reduced. This unidirectional cloaking method is valid for both TM/TE and non-TM/TE incident field and is not limited to a plane-wave incident field. The accuracy and effectiveness of the method are verified by four cloaking scenarios in microwave regime. We demonstrate that with the surface impedance obtained by the proposed method, a metasurface is designed with physical subwavelength structures. We also show a cloaking scenario under a magnetic dipole radiation, which is closer to the case of a realistic antenna. This method can be further applied to cloaking tasks in terahertz and optical regimes.
Characterizing two-mode-squeezed light from four-wave mixing in rubidium vapor for quantum sensing and information processing
Authors: de Araujo Luís E. E. , Zhou Zhifan , DiMario Matt , Anderson B. E. , Zhao Jie , Jones Kevin M. , Lett Paul D.
Published: December 2023

We present a study of homodyne measurements of two-mode, vacuum-seeded, quadrature-squeezed light generated by four-wave mixing in warm rubidium vapor. Our results reveal that the vacuum squeezing can extend down to measurement frequencies of less than 1 Hz, and the squeezing bandwidth, similar to the seeded intensity-difference squeezing measured in this system, reaches up to approximately 20 MHz for typical pump parameters. By dividing the squeezing bandwidth into smaller frequency bins, we show that different sideband frequencies represent independent sources of two-mode squeezing. These properties are useful for quantum sensing and quantum information processing applications. We also investigate the impact of group velocity delays on the correlations in the system, which allows us to optimize the useful spectrum.

We employ multi-wavelength 3D imaging with digital holography and a pilot tone to obtain the aberrated images and use sharpness metric maximization to correct the aberrated images with both pupil-plane and multi-plane corrections. Image quality improves when sharpness metric maximization is used and particularly with multi-plane correction.
Burst-mode velocimetry of hypersonic flow by nitric oxide ionization induced flow tagging and imaging
Authors: Leonov Boris S. , Moran Ashley N. , North Simon W. , Miles Richard B.
Published: December 2023

This Letter describes, to the best of our knowledge, a new approach to flow tagging, nitric oxide (NO) Ionization Induced Flow Tagging and Imaging (NiiFTI), and presents the first experimental demonstration for single-shot velocimetry in a near Mach 6 hypersonic flow at 250 kHz. The mean velocity of 860 m/s was measured with a single-shot standard deviation of as low as 3.4 m/s and mean velocity uncertainty of 5.5 m/s. NiiFTI is characterized by a long fluorescence lifetime of nitrogen with 1e decay of approximately 50 μs measured in air. The method relies on a single nanosecond laser combined with a high-speed camera, creating an opportunity for the utilization of a typical nitric oxide (NO) laser-induced fluorescence (LIF) experimental setup with minor modifications as well as pulse-burst lasers (PBLs) for ultrahigh repetition rates.
Snapshot compressive structured illumination microscopy
Authors: Luo Runqiu , Cao Miao , Liu Xing , Yuan Xin
Published: December 2023

We propose a snapshot compressive structured illumination microscopy (SoSIM) system to increase the number of reconstructed resolution-enhanced (RE) images per second and reduce the data bandwidth by capturing compressed measurements. In this system, multiple low-resolution images are encoded by a high-speed digital micro-mirror device with random binary masks. These images are then captured by a low-speed camera as a snapshot compressed measurement. Following this, we adopt an efficient deep neural network to reconstruct nine images with different structured illumination patterns from a single measurement. The reconstructed images are then combined into a single-frame RE image using the method of spectral synthesis in the frequency domain. When the camera operates at 100 frames per second (fps), we can eventually recover dynamic RE videos at the same speed with 100 fps.

Authors: Guo Lu , Wang Yun-Hao , Cui Rui , Huang Zhou , Hong Yuan , Qian Jia-Wei , Ni Bin , Xu An-Ming , Jiang Cheng-Ying , Zhulin Igor B. , Liu Shuang-Jiang , Li De-Feng
Published: December 2023

Motile bacteria navigate toward favorable conditions and away from unfavorable environments using chemotaxis. Mechanisms of sensing attractants are well understood; however, molecular aspects of how bacteria sense repellents have not been established. Here, we identified malate as a repellent recognized by the MCP2201 chemoreceptor in a bacterium Comamonas testosteroni and showed that it binds to the same site as an attractant citrate. Binding determinants for a repellent and an attractant had only minor differences, and a single amino acid substitution in the binding site inverted the response to malate from a repellent to an attractant. We found that malate and citrate affect the oligomerization state of the ligand-binding domain in opposing way. We also observed opposing effects of repellent and attractant binding on the orientation of an alpha helix connecting the sensory domain to the transmembrane helix. We propose a model to illustrate how positive and negative signals might be generated.

Analisamos neste artigo, a partir de uma perspetiva feminista interseccional, a cobertura mediática de dois deputados únicos representantes de partidos estreantes no Parlamento português, em 2019: André Ventura e Joacine Katar Moreira. Por meio de uma Análise de Conteúdo qualitativamente orientada, examinamos a produção informativa de três diários generalistas portugueses de circulação nacional (Correio da Manhã, Diário de Notícias e Público) sobre a deputada e o deputado durante os seis primeiros meses da XIV legislatura da Terceira República Portuguesa. Foram identificados padrões que, apesar de desafiarem a tradicional invisibilidade das mulheres parlamentares, contribuem para uma representação genderizada, enquanto favorecem a polarização dos atores políticos.
Convenções jornalísticas e mudança política no início do século XX
Authors: Leitão de Barros Júlia
Published: December 2023

O presente trabalho é um contributo para a reflexão do processo de democratização da vida política portuguesa, na viragem do século XIX para o século XX, através da análise da alteração na forma de comunicar o assunto político nos jornais diários portugueses.

A titulação das peças jornalísticas inclui-se entre os dispositivos comunicacionais disponíveis, no final do século XIX, para destacar e facilitar a leitura das notícias atuais. Através da análise do uso do título, na primeira página, em seis jornais diários de Lisboa, no período de 1889 a 1907, defendo que, até ao início do século XX, prevaleceu uma convenção jornalística hostil ao uso de títulos grandes que destacassem o assunto político. Esta rompe-se com a adoção de novas práticas de titulação que alteraram a leitura do jornal, facilitando o acesso ao assunto político, favorecendo a afirmação de uma nova representação do político, mais democrática, uma arena aberta ao alcance de todos.
Uma análise temática à imprensa partidária portuguesa
Authors: Magalhães Catarina
Published: December 2023

Desde 2019, o partido liderado por André Ventura tem sido disruptivo no cenário político nacional e contrariado a tese da impermeabilidade portuguesa (Mudde, 2020; Serrano, 2020) à eleição de partidos populistas. Assim, neste trabalho pretende analisar-se uma das estratégias de comunicação em particular: a publicação doutrinária Folha Nacional do partido Chega. Através de uma análise temática complementada com uma breve análise de conteúdo, o nosso estudo foca duas dimensões: a agenda da publicação e os protagonistas das capas. Assim, procuraremos a resposta às seguintes questões: 1) Quais os principais temas destacados? 1.1) Qual a proximidade temática com a ‘agenda populista’ de partidos populistas de direita? 2) Quem são os protagonistas identificados? e 2.1.) Como são enquadrados os diferentes protagonistas? Percebemos, sobretudo, que a publicação é utilizada, maioritariamente, como plataforma de crítica a adversários.

REORGANIZING HIGHER ECONOMIC EDUCATION: EMBRACING PERSONALISM AND MOVING BEYOND THE BOLOGNA PROCESS IN METHODOLOGY AND THEORY
Authors: Kryshka V. I. , Belyaev V. I.
Published: December 2023

The article presents an evaluation of the current state of economic education’s theoretical “core” and proposes a shift towards a personalistic approach in response to the emergence of a multipolar world in politics. Drawing on research supported by the Russian Foundation for Basic Research (RFBR), the article identifies four types of reproduction in the market economic system as the “core” of national economic education: goods, people, man, and knowledge. The adoption of a personalistic approach within these types of reproduction can provide a balance between Western individualism and Eastern holism associated with socialism and communism.

MARKETING AS A FACTOR OF PROPORTIONAL ECONOMIC DEVELOPMENT (A PROBLEM REQUIRING RESEARCH)
Authors: Belyaev V. I. , Kuznecova O. V. , Pyatkova O. N.
Published: December 2023

All problems can be divided into two groups: problems that require solutions and problems that require research. The second group includes complex hidden problems, which are sometimes difficult to identify, designate, define, describe, and establish the causes. In a market economy, this is the problem of ensuring the proportionality of production and consumption, both in general, in the country's economy, and in a separate commodity flow. The formation of production and marketing infrastructure in market conditions is stochastic in nature, that is, it is carried out in the form of spontaneous interactions of sellers and buyers, as well as producers among themselves. As a result, the formation of the proportions of the development of the country's economy is formed mainly on the decisions of enterprises on the volume of production of products and their offer to the market, taking into account the volume of demand and competitive interactions. It is impossible to make a quantitative forecast for either of them. This is the essence of the problem that requires research. The article, with reference to many literary sources, provides a justification for the possibility of using marketing as a management function to streamline the structure and content of large (national) economic systems and increase their efficiency.

Authors: Belyaev V. I. , Mishchenko V. V. , Rudakova O. Yu.
Published: December 2023

The article highlights the issues of creation and development of young universities. Important historical aspects of the formation and development of higher education are noted, both in European countries and in Russia. The classification of university development factors is presented and considered. Two groups of factors are singled out: purely external (political, material, financial) and factors, the sources of resources for the formation of which are both external and internal capabilities of universities (socio-cultural, intellectual factors). The products produced by universities are defined: individual intellectual capital and socially significant social capital, scientific knowledge, culture. It has been established that culture is created and transmitted to university students by their faculty and leaves the university together with graduates, creating a reputation for the university in the external environment. At the same time, leaving the university, culture, at the same time, remains at the university. In this case, it performs the function of a factor in its development.
SOME FEATURES OF THE MODERN DEVELOPMENT OF THE CHINESE ECONOMIC MODEL
Authors: Obiremko S. I. , Liu Jianlu
Published: December 2023

The article reveals the merits and shortcomings of the Chinese economic development model. A critical analysis of Western approaches to the study of the features of the national model of the Chinese economy is proposed. The fundamental principle of the formation of the Chinese national economic model — “democratic centralism” is considered. The article focuses on the analysis of the demographic factor of the formation of the Chinese economic model. In particular, his assessment from the point of view of the theory of “human capital”. The authors propose to assess the consequences of large-scale investments in the education and healthcare system in China from the standpoint of capitalization of the demographic factor and a critical assessment of the “demographic dividend”.

Much attention is paid to the insufficiently analyzed features of the tax policy of the People's Republic of China. An assessment of the specifics of structural policy in the field of industrial policy implementation is given.

At the same time, the authors are far from idealizing the Chinese economic model and proceed from its uniqueness associated with such fundamental factors of the formation of the model as the historical path of the country, the mentality of the peoples inhabiting it.

Published: December 2023

The modern world order and geopolitical risks have caused large-scale changes that have spread to all spheres of the economy and the behavior of subjects of socio-economic activity. The world market as an integral part of the world economy, on the one hand, is a platform for the exchange between participants in trade operations, based on stable interstate commodity-money relations, on the other hand, it is a sphere of collision of emerging contradictions between participants in market trade and the struggle for competitive markets. Violation of international economic, interregional and intersubjective relations due to changes in the value chain, disproportion in the distribution of value between participants in trade relations limits the possibility of using previously formed mechanisms and instruments of international cooperation and becomes a factor in the search for new points of contact and new partners in the processes of international and interregional interaction. The relevance of the study is dictated by the key task of national and international development — the transformation of the economic system, ensuring its stability and viability in the face of turbulence and uncertainty, accumulated experience, opportunities and limitations. The scientific novelty of the study lies in the formation of new views on the problems of organizing economic relations among participants in the global market.
Performances en lecture et pratiques de classe en Fédération Wallonie-Bruxelles :

Published: December 2023

Au printemps 2021, les élèves de quatrième primaire de la Fédération Wallonie-Bruxelles ont pris part à l’enquête Progress in International Reading and Literacy Study (PIRLS) organisée par l’IEA. Tous les cinq ans, cette étude évalue la compréhension de l’écrit à un moment charnière de la scolarité où les élèves sont fréquemment amenés à lire pour acquérir des connaissances dans les différentes disciplines scolaires. 
Cet article met le projecteur sur quelques résultats saillants de PIRLS 2021. Les faibles performances moyennes des élèves de la FW-B sont mises en parallèle avec la nature des activités visant à développer la lecture en quatrième année primaire. Nos résultats montrent que celles-ci ciblent peu le développement des démarches d’autoévaluation et de régulation de leur compréhension par les élèves. Les lectures effectuées dans le cadre scolaire apparaissent essentiellement exploitées dans une visée d’évaluation du produit de la compréhension.  La place accordée au développement des démarches d’appréciation demeure restreinte. Quant aux échanges entre lecteurs et aux écrits d’appropriation, leur fréquence demeure faible à ce niveau scolaire. Ces pratiques constituent pourtant des leviers indispensables à l’amélioration des compétences en lecture, que l’on considère celle-ci selon une approche cognitive ou socioculturelle. Point de ralliement entre ces deux approches, la dimension réflexive de la lecture cible la capacité d’autoréguler sa compréhension mais également la capacité à prendre de la distance pour réfléchir à propos d’un texte et justifier son appréciation personnelle. Il nous semble urgent que cette dimension s’ancre dans les pratiques de classe dès le début de l’enseignement primaire.
Vrstna sestava aerofitskih alg na izbranih lokacijah v Sloveniji nakazuje dinamične spremembe v združbi
Authors: Krivograd Klemenčič Aleksandra , Balabanič Damjan
Published: December 2023

In the years 2005 and 2006, algal samples were collected seasonally at five different aerophytic sampling sites. We compared samples from decayed wood stump, limestone rocks, concrete and soil. The samples were collected from a stump of Picea abies on the Jelovica plateau, damp rocks at Šica spring on Radensko polje, karst cave Huda luknja entrance and at the abandoned railway tunnel near Huda luknja cave. Altogether, 17 algal samples were collected. 94 algal taxa from 38 genera and four classes were determined. Most of them belonged to diatoms, followed by cianobacteria, Chlorophyceae and Xanthophyceae. Bacillariophyceae were the predominant group of algae on wet rocks at Šica spring, karst cave Huda luknja entrance and on the abandoned railway tunnel, while the Chloprophyceae were predominant on a stump of Picea abies on the Jelovica plateau. At other localities, Bacillariophyceae prevailed. Altogether, 20 taxa were identified for the first time in Slovenia. The genera Podohedra and Poloidion are new records for Slovenia. The algal community was also influenced by the type of substrate colonized by aerophytic algae.

First record of the Greek clouded yellow Colias aurorina Herrich-Schäffer, 1850 (Lepidoptera: Pieridae) for Albania
Authors: Verovnik Rudi , Popović Miloš
Published: December 2023

During our field survey in the south-eastern part of the Republic of Albania, we encountered the Greek clouded yellow (Colias aurorina) at two sites, representing the first record for the species in Europe outside Greece. It was found common at one site on the Albanian side of the Grammos Mts. with possibly continuous range into northern Greece. As larval host plant of the Greek clouded yellow Astragalus thracicus was present in abundance on the northern slopes of the mountain, we consider the species as not threatened in Albania. In addition, the purple emperor (Apatura iris) and the Balkan green-veined white (Pieris balcana) were recorded for the first time in Albania.
De Prunner’s Ringlet Erebia triaria (de Prunner, 1798) (Lepidoptera: Nymphalidae: Satyrinae) – a new species for the Republic of Macedonia
Authors: Micevski Nikola
Published: December 2023

A single male of de Prunner’s Ringlet Erebia triaria (de Prunner, 1798) was discovered in the lower part of the Jadovska River Valley, near the Selce village in NW part of Macedonia. This is the first record for Macedonia and only the fourth in the Balkan Peninsula, where it is extremely local. This moves the southeasternmost distribution border of the species for about 120 km. This discovery brings the number of butterfly species for Macedonia to 206
Checklist of Croatian amphibians and reptiles with bibliography of 250 years of research
Authors: Jelić Dušan
Published: December 2023

An updated checklist is presented for the amphibian and reptile fauna of Croatia. According to historical and recent literature sources, 20 amphibian and 41 reptile species have been recorded so far. Two reptile species, Blanus strauchi and Typhlops vermicularis, are considered doubtful, although there are individual museum vouchers for the country. Presence of a total of 59 species can be considered valid, with two additional considered doubtful. This paper summarizes data from 700 scientific and popular publications, which is the first attempt to publish a complete Croatian herpetological bibliography. Full bibliography is also given for all occurring species and constitutes a basis for future publications.

A twist of nature: a left-handed Bythinella schmidti (Küster, 1852) (Caenogastropoda: Bythinellidae)
Authors: Prevorčnik Simona , Falniowski Andrzej
Published: December 2023

As most extant snails, Bythinella schmidti is characterised by dextral (right-handed) coiling of the shell. Nevertheless, a small sinistral (left-handed) individual from the spring on a mountain pasture was sampled, together with its larger dextral conspecifics. In our report on this first case of sinistrality within the superfamily Truncatelloidea, we discuss its shell abnormalities and provide a review on chirality in snails.

Checklist of amphipod crustaceans (Crustacea: Amphipoda) in Slovenia
Authors: Fišer Cene , Mavrič Borut , Govedič Marijan , Pekolj Anja , Zagmajster Maja
Published: December 2023

Amphipods are among the most species-rich orders of peracarid crustaceans, inhabiting marine and fresh waters, including subterranean waters, as well as semi-terrestrial environments. Data on amphipods from Slovenia are scattered among published and unpublished references. We gathered all available data on amphipods in the country, using published and unpublished records from two databases, supplemented by additional published information and unpublished records from two collections of two institutions. All data were critically evaluated and species names updated to the latest taxonomically valid name. In total, we listed 198 species, belonging to 85 genera and 41 families. About two thirds of the species are marine, while the rest are semiterrestrial, brackish and freshwater species. Among the latter, subterranean species dominate. In total, 26 species endemic to Slovenia were identified, one of which lives in surface freshwater, and the rest in groundwaters. Surprisingly, no presence of invasive freshwater amphipod species has currently been confirmed. We provided critical comments on nine amphipod species that were listed erroneously for the country. Our work revealed two major knowledge gaps. Marine species records come from occasional sampling campaigns, and we suggest that this group calls for a more systematic research. More work has been done on freshwater species, which revealed many taxonomic uncertainties that cannot be resolved at present and call for additional taxonomic research.
Kopenske alge na betonskem zidu, kamnitem zidu, apnenčasti skali in deblu lipe (Tilia platyphyllos) v Sloveniji
Authors: Krivograd Klemenčič Aleksandra
Published: December 2023

Samples were taken seasonally at four aerial sampling sites – a concrete wall, stony wall, limestone rock and trunk of the lime tree (Tilia platyphyllos) in the years 1999 and 2000. Altogether, 58 species and subspecies of algae (of three classis) were determined. On the concrete wall and the lime tree trunk, most of the species and subspecies belonged to Cyanophyceae, while on the stony wall and limestone rock those belonging to Bacillariophyceae were predominant. On the concrete wall, stony wall and the lime tree trunk, the species Pleurococcus vulgaris was prevalent. Gloeocapsa bituminosa, Microcystis hansgirgiana, Phormidium lignicola, P. valderiae, Cymbella gaeumannii, Navicula aerophila, N. nivalis and N. suecorum var. dismutica are new species and subspecies to Slovenia.
