Published: January 2024

Abstract
InAs/AlSb quantum cascade detectors (QCDs) grown strain-balanced on GaSb substrates are presented. This material system offers intrinsic performance-improving properties, like a low effective electron mass of the well material of 0.026 m
0, enhancing the optical transition strength, and a high conduction band offset of 2.28 eV, reducing the noise and allowing for high optical transition energies. InAs and AlSb strain balance each other on GaSb with an InAs:AlSb ratio of 0.96:1. To regain the freedom of a lattice-matched material system regarding the optimization of a QCD design, submonolayer InSb layers are introduced. With strain engineering, four different active regions between 3.65 and 5.5 µm were designed with InAs:AlSb thickness ratios of up to 2.8:1, and subsequently grown and characterized. This includes an optimized QCD design at 4.3 µm, with a room-temperature peak responsivity of 26.12 mA/W and a detectivity of 1.41 × 108 Jones. Additionally, all QCD designs exhibit higher-energy interband signals in the mid- to near-infrared, stemming from the InAs/AlSb type-II alignment and the narrow InAs band gap.

Abstract
This study explores the optical design of a daytime radiative cooler with near-ideal solar reflectance and longwave infrared (LWIR) emittance through materials selection and nanostructuring. Focusing on polymers as a materials platform, we introduce a bilayer architecture, comprising a porous poly(vinylidene fluoride-co-hexafluoropropene) (P(VdF-HFP)) topcoat that serves as a low-index LWIR emissive effective medium, over a nanofibrous, solar scattering polytetrafluoroethene underlayer. This novel configuration yields a superwhite coating with a near-ideal solar reflectance of >0.99, and a blackbody-like near-normal and hemispherical LWIR emittances of ∼0.98 and ∼0.96 respectively. Under humid and partially cloudy sky conditions unfavorable for radiative heat loss, these values enable the bilayer radiative cooler to achieve a sub-ambient of 2.3 °C. Given that the porous polymer bilayer uses scalable fabrication processes and commercially available materials, it holds significant promise for device-scale, as well as building thermoregulation applications.

Developments of terahertz metasurface biosensors: A literature review
Authors: Zhang Zhongquan , Zhao Rui , Cong Mengyang , Qiu Jianfeng 
Published: January 2024

Abstract
Terahertz metasurface (THz-MS) biosensor is a hybrid technology that combines terahertz time-domain spectroscopy and metasurface for the detection of biomolecules and cells. Compared with traditional strategies, it is label-free, non-invasive, time-saving, and easy to operate. However, three fundamental issues, namely, low sensitivity, low specificity, and drastic water absorption, hinder the development of THz-MS biosensors for clinical application. Recently, numerous studies of THz-MS biosensors have been performed to solve these problems, and the results show great potential for the sensitive detection of nucleotides, proteins, and cells. Therefore, it is important to summarize the development of THz-MS biosensors in biomedical detection. In this review, we summarized the mechanism, manufacturing, and implementation of THz-MS biosensors. Then, strategies to improve the sensitivity, selectivity, and means to reduce water absorption are presented. Sensitivity can be improved by suppressing electromagnetic radiation and strengthening the interaction between target molecules and meta-atoms. Antibodies and aptamers are the most effective strategies for improving specificity. Microfluidics and hydrogels are two potential ways to reduce the water absorption. Subsequently, the applications of the THz-MS biosensors for the detection of nucleotide, proteins, and cells are summarized. Finally, the prospects for the future development of THz-MS biosensors are outlined.
Russische Kriegssemantik zwischen GULAG-Trauma und Antiamerikanismus
Authors: Khislavski Grigori 
Published: January 2024

ZusammenfassungDas Konzept des russischen Angriffskrieges gegen die Ukraine hängt von dessen Semantisierung durch unterschiedliche politische, gesellschaftliche und kulturelle Systeme ab, die ein spezifisches Geschichtsbewusstsein konstituieren. Dadurch erscheint der ‚Krieg‘ als ein relationaler Begriff. In diesem Aufsatz soll aufgezeigt werden, inwieweit das kollektive GULAG-Trauma und der Antiamerikanismus die Semantik des russischen Angriffskrieges gegen die Ukraine beeinflussen. Die Pejorisierung und Dämonisierung des ukrainischen politischen Systems als Nazi-Regime umfasst zahlreiche anti-amerikanische Konnotationen, sodass das semantische Feld nicht nur aus dem Zweiten, sondern vornehmlich aus dem Kalten Krieg generiert wird. Hinzu kommen scheinbar disparate Elemente aus der Gefängniskultur und der politischen Doktrin desRusskij Mir. Diese werden in letzter Zeit durch antisemitische Verschwörungsmythen ergänzt, die etwa für die Sprache der Neuen Rechten typisch sind. Die Alltäglichkeit des GULAG-Vokabulars, insbesondere in Bezug auf sexualisierte Gewalt, zeigt die langfristigen Auswirkungen des Stalinismus auf die russische Gesellschaft.
Denis Pushilin: Case study of a separatist leader in the Ukraine conflict (2018–2022)
Authors: Melgar Rodrigo , Saravia José Antonio 
Published: January 2024

AbstractOn 20 November 2018 Denis Vladimirovich Pushilin became the Head of the unrecognised Donetsk People’s Republic in Eastern Ukraine. Despite his numerous proclamations aligning him with the Kremlin’s propaganda apparatus, his style and imagery differs from that of Vladimir Putin. To dissect Pushilin’s constructed image we used a discourse analysis methodology focusing on primary sources such as speeches, songs, images, and photographs uploaded to either Pushilin’s social media accounts or the DPR administration’s official website. Our research analyses Pushilin’s government from the day he assumed power until the 23 February 2022, with the onset of the war in Ukraine. Our analysis focuses on core aspects of his constructed image, such as nationalism, sports as well as gender and family politics. Our findings show that while Denis Pushilin does adhere to Kremlin directives when it comes to issues crucial to Moscow, he does enjoy certain freedom when it comes to his image construction.

As the first French initiative to ever investigate this collection, the project aims to show how the alternative data provided by these letters can broaden the scope by filling the gaps left by traditional historical linguistics, focusing on one of French’s greatest periods of expansion and shedding new light on the dynamics and mechanisms that led to the existing French and creole varieties in America and in the Indian Ocean.
The system of pronouns of address in the Azores
Authors: Lara Bermejo Víctor 
Published: January 2024

Abstract
The system of pronouns of address in European Portuguese is made up of several pronouns and strategies, some of which vary depending on sociolinguistic, geographical and pragmatic factors. Despite its complexity, there is lack of empirical research that accounts for the actuality and validity of the paradigm depicted in the grammars. In order to compensate for this lack of information, I aim to set out the system of pronouns of address in the Azores, an area that has up to this point not been subject to investigation. Thanks to specific fieldwork, I will establish the type of politeness that currently predominates in this archipelago and the particularities that are not attested elsewhere in Portugal.

Cornejo-Daza, PJ, Sánchez-Valdepeñas, J, Rodiles-Guerrero, L, Páez-Maldonado, JA, Ara, I, León-Prados, JA, Alegre, LM, Pareja-Blanco, F, and Alcazar, J. Vastus lateralis muscle size is differently associated with the different regions of the squat force-velocity and load-velocity relationships, rate of force development, and physical performance young men. J Strength Cond Res XX(X): 000–000, 2023—The influence that regional muscle size and muscle volume may have on different portions of the force-velocity (F-V) and load-velocity (L-V) relationships, explosive force, and muscle function of the lower limbs is poorly understood. This study assessed the association of muscle size with the F-V and L-V relationships, rate of force development (RFD) and maximal isometric force in the squat exercise, and vertical jump performance via countermovement jump (CMJ) height. Forty-nine resistance-trained young men (22.7 ± 3.3 years old) participated in the study. Anatomical cross-sectional area (ACSA) of the vastus lateralis (VLA) muscle was measured using the extended field of view mode in an ultrasound device at 3 different femur lengths (40% [distal], 57.5% [medial], and 75% [proximal]), and muscle volume was estimated considering the VLA muscle insertion points previously published and validated in this study. There were significant associations between all muscle size measures (except distal ACSA) and (a) forces and loads yielded at velocities ranging from 0 to 1.5 m·s−1 (r = 0.36–0.74, p < 0.05), (b) velocities exerted at forces and loads ranging between 750–2,000 N and 75–200 kg, respectively (r = 0.31–0.69, p < 0.05), and (c) RFD at 200 and 400 milliseconds (r = 0.35–0.64, p < 0.05). Proximal and distal ACSA and muscle volume were significantly associated with CMJ height (r = 0.32–0.51, p < 0.05). Vastus lateralis muscle size exhibited a greater influence on performance at higher forces or loads and lower velocities and late phases of explosive muscle actions. Additionally, proximal ACSA and muscle volume showed the highest correlation with the muscle function measures.

Published: January 2024

Solvent and substitution effects on the UV/Vis spectroscopic and fluorescence behaviour of seven synthesized 3-substituted 4-hydroxycoumarin derivatives were tested. The tested compounds were dissolved in ethyl acetate, acetonitrile, and dimethyl sulfoxide. Absorption and emission spectra were recorded in the range of 200–800 nm. All tested 4-hydroxycoumarin derivatives showed good absorption in a wide range of 200–550 nm, depending on the properties of the substituents on the benzene ring of the cinnamoyl moiety and the type of solvent. In comparison to the unsubstituted analogue, compounds with an electron-donating group exhibited bathochromically shifted UV/Vis absorption and emission spectra. The highest fluorescence quantum yield was observed for compounds with dimethylamino and acetamido groups as substituents at the benzene ring. Considering that both substitution and solvent affect the absorption and emission spectra of the tested compounds, it can be concluded that judiciously selecting these parameters can improve their absorption and fluorescence properties, making them suitable for various analytical uses.

Published: January 2024

AbstractDirect current (DC) motors have superior features such as operating at different speeds, being affordable and easily controllable. Therefore, DC motors have many uses, such as machine tools and robotic systems in many factories up to the textile industry. The PID controller is one of the most common methods used to control DC motors. PID is a feedback controller with the terms Proportional, Integral, and Derivative. The proper selection of P, I, and D parameters is critical for achieving the desired control in the PID controller. In this study, the transfer function of a DC motor is first obtained, and the speed of the DC motor is controlled by the PID controller using this transfer function. Then, Particle Swarm Optimization (PSO), an optimization method based on swarm intelligence, is used to adjust the P, I, and D parameters. By using the obtained P, I, and D coefficients, the speed of the DC motor is tried to be controlled, and the effect of the filter coefficient on the system output is examined. The performance of the proposed PSO-PID controller with successful results is given in tables and graphics. Control and optimization studies are carried out with MATLAB Simulink.

Published: January 2024

AbstractAimThe ability of neutrophil CD16 (nCD16) expression to predict outcome in complicated intra-abdominal infections (cIAIs) has not yet been studied; therefore we aimed to evaluate its potential prognostic value in such patients.MethodsBetween November 2018 and August 2021 a single-center prospective study was performed in the Department of Surgical Diseases at a University Hospital Stara Zagora. A flow cytometry was used to measure the levels of nCD16 before surgery and on the 3rd postoperative day (POD) in 62 patients with cIAIs.ResultsWe observed a mortality rate of 14.5% during hospitalization. Survivors had significantly higher perioperative expression of nCD16 than non-survivors (P = 0.02 preoperatively and P = 0.006 postoperatively). As predictor of favorable outcome we found a good predictive performance of preoperative nCD16 (AUROC = 0.745) and a very good predictive performance of postoperative levels (AUROC = 0.846). An optimal preoperative threshold nCD16 = 34.75 MFI permitted prediction of survival with sensitivity and specificity of 66.7% and 77.8%, respectively. A better sensitivity of 72.5% and specificity of 85.7% were observed for threshold = 54.8 MFI on the 3rd POD.ConclusionPerioperative neutrophil CD16 expression shows a great potential as a predictor of favorable outcome in patients with cIAIs.

Published: January 2024

AbstractTo assess the chemical durability of the Belgian reference glasses SON68, SM513, and SM539 under hyper-alkaline conditions, maximum glass dissolution rates were measured at 30 °C and pH 13.5 by performing Single-Pass Flow-Through tests with a KOH solution and a synthetic young cementitious water containing Ca (YCWCa). In both leachants, the highest dissolution rate was determined for the Al-rich glass SM539, while similar rates were found for SM513 and SON68 glasses, whose compositions are comparable. For all glasses, the dissolution rates in YCWCa were lower than in KOH due to the presence of Ca, which leads to the formation of a slightly protective calcium silicate layer. The dissolution rates in YCWCa were similar to those determined from glass monolith mass losses in static tests carried out at 30 °C in YCWCa in the presence of hardened Ordinary Portland Cement paste powder with a cement-to-glass ratio of 1.
