Synthesis of Thiazole-fused Tricyclic Quinazolinone Alkaloids and Their Derivatives
Authors: Besson Thierry , Broudic Nathan , Layec Corentin , Fruit Corinne 
Published: January 2024

AbstractThe synthesis of thiazole-fused derivatives of tricyclic quinazolinones hitherto undescribed was successfully achieved by replacing anthranilic acid or its derivatives by isomeric polyfunctionalized benzothiazole analogues of anthranilic methyl esters. Some of the new heterocyclic systems are inspired by natural alkaloids such as mackinazolinone, deoxyvasicinone, and isaindigotone, showing interesting biological properties. The microwave-assisted method developed is a variant of the Niementowski reaction and was also applied to the synthesis of ring-extended rutaecarpine derivatives.

Published: January 2024

AbstractAmong all clinical manifestations of pulmonary aspergillosis, invasive pulmonary aspergillosis (IPA) is the most acute presentation. IPA is caused by Aspergillus hyphae invading the pulmonary tissue, causing either tracheobronchitis and/or bronchopneumonia. The degree of fungal invasion into the respiratory tissue can be seen as a spectrum, going from colonization to deep tissue penetration with angio-invasion, and largely depends on the host's immune status. Patients with prolonged, severe neutropenia and patients with graft-versus-host disease are at particularly high risk. However, IPA also occurs in other groups of immunocompromised and nonimmunocompromised patients, like solid organ transplant recipients or critically ill patients with severe viral disease. While a diagnosis of proven IPA is challenging and often warranted by safety and feasibility, physicians must rely on a combination of clinical, radiological, and mycological features to assess the likelihood for the presence of IPA. Triazoles are the first-choice regimen, and the choice of the drug should be made on an individual basis. Adjunctive therapy such as immunomodulatory treatment should also be taken into account. Despite an improving and evolving diagnostic and therapeutic armamentarium, the burden and mortality of IPA still remains high. This review aims to give a comprehensive and didactic overview of the current knowledge and best practices regarding the epidemiology, clinical presentation, diagnosis, and treatment of acute IPA.

Published: January 2024

Objective To evaluate the sensitivity and specificity of clinical, laboratory, and radiological markers and the neonatologist-performed intestinal ultrasound (NP-IUS) for treatment interventions in preterm neonates who developed necrotizing enterocolitis (NEC).
Study Design This was a case–control study of preterm neonates < 35 weeks with a diagnostic workup for NEC. The diagnostic workup included NP-IUS performed by trained neonatologists using a standard protocol, abdominal roentgenogram (AXR), and laboratory investigations. Intestinal ultrasound (IUS) performed by two neonatologists was standardized to detect 11 injury markers. AXRs were read independently by experienced pediatric radiologists. The investigators who retrospectively interpreted the IUS were blinded to the clinical and treatment outcomes.
Results A total of 111 neonates were assessed. Fifty-four did not require intervention and formed the control group. Twenty cases were treated medically, 21 cases were treated with late surgery for stricture or adhesions, and 16 were treated with early surgery. The integrated model of cumulative severity of ultrasound markers, respiratory and hemodynamic instability, abdominal wall cellulitis, and C- reactive protein > 16 mg/L had an area under the curve (AUC) of 0.89 (95% confidence interval [CI]: 0.83–0.94%, p < 0.0001) for diagnosing NEC requiring surgical intervention. We also investigated the utility of Bell's classification to diagnose either the need for surgery or death, and it had an AUC of 0.74 (95% CI: 0.65–0.83%, p < 0.0001).
Conclusion In this cohort, a combination of specific IUS markers and clinical signs of instability, abdominal wall cellulitis, plus laboratory markers were diagnostic of NEC requiring interventions.

The voice astray: Caroline Bergvall’s Dante
Authors: Southerden Francesca 
Published: January 2024

AbstractThis article analyses ‘Via: 48 Dante Variations’ by Caroline Bergvall (1962-) and considers the kind of Dante it performs. ‘Via,’ composed of the first tercet of Dante’s Inferno, accompanied by 47 (or 48) English translations of the tercet ordered alphabetically, was first divulged as a sonic piece and was then published in diverse textual iterations, with variants among the several written forms and between the spoken and written. I explore the links between Bergvall’s project and medieval textual practices and textualities, particularly the creative instability of works that exhibit mouvance and variance within a hybrid aural/textual culture. Engaging with recent critical work on queer philology and with Ovid’s myth of Echo, I consider how Bergvall’s ‘Via’ can be said to perform error, extending the predicament of the Dantean ‘I’ at the opening of Inferno, and how that performance of error may be a source of queer pleasure.

Published: January 2024

AbstractFintech has gained immense importance as a catalyst for economic growth, trade enhancement, and global prosperity. This study aims to comprehensively assess the influence and potential of Fintech in the Association of Southeast Asian Nations (ASEAN) countries. The research objective is to evaluate the levels of development in financial activities, technology infrastructure, and Fintech-enabling regulations across the region. A robust decision-making framework combining numerical and linguistic assessments is applied, utilizing the Distance-based CRiteria Importance Through Inter-criteria Correlation (DCRITIC) method and the Fuzzy extension of Evaluation based on Distance from Average Solution (F-EDAS approach). The findings reveal varying levels of development among ASEAN countries about Fintech. Governments and policymakers are urged to prioritize the creation of a supportive environment for Fintech innovation to spur economic growth, attract investments, and foster digital transformation. The study is limited because the weights of the key regulations have not been investigated.

Published: January 2024

The underwater electric field (UEF) signature of a ship is a key factor in its survivability in marine warfare. Moreover, the study of a ship’s UEF using scale models of ships in pools can be useful for the design of electromagnetically stealthy ships. Aiming at the system requirement of measuring and analyzing the UEF of scale models of ships with low noise, many channels, and real-time responsivity, we developed a system consisting of electrode sensors, a measuring device, and a personal computer (PC). Small Ag/AgCl electrodes with low noise and high stability were used. The measuring device was capable of simultaneously amplifying, sampling, and storing 24 channels of UEF data in real-time, and it was connected to the PC via Ethernet to facilitate the transfer of UEF data at high speeds. The PC software could display 24 low-frequency UEF curves in real time and perform spectral analysis and filtering of the UEF signals. In system performance tests, we found that the system had a noise floor lower than 6.34 nV/rt(Hz)@1 Hz and could simultaneously sample 24 channels of UEF signals while storing, displaying, and analyzing the signals in real-time. The primary functions of the system were also validated in a pooled experiment.

Published: January 2024

The Ion Cyclotron Range of Frequency (ICRF) heating system of the China Fusion Engineering Test Reactor (CFETR) is intended to provide plasma heating with a minimum power output of 20 MW, which demands the Radio Frequency (RF) window to possess a higher performance requirement. This paper presents the design of an RF window for the CFETR ICRF heating system and focuses primarily on the design and confirmation of its electromagnetic performance. The RF window can be effectively matched in the operating frequency range and has an S11 of under −59 dB. The geometry of the cone type ceramics was optimized to reduce the surface tangential electric field distribution. An analysis of the electric field distribution of the RF window at 50 kV indicates that the pressure side was below 2.3 kV/mm and the vacuum side was below 1.3 kV/mm. Furthermore, a transmission line test bench with an open-terminated setup was constructed to conduct withstand voltage tests on the mockup, and the results showed that the mockup could withstand 62 kV for 2 s and 47 kV for 120 s.

Published: January 2024

Understanding polymer transport in nanopores is crucial for optimizing heterogeneously catalyzed processes in polymer upcycling and fabricating high-performance nanocomposite films and membranes. Although confined polymer dynamics have been extensively studied, the behavior of polyethylene (PE)—the most widely used commodity polymer—in pores smaller than 20 nm remains largely unexplored. We investigate the effects of extreme nanoconfinement on PE transport using capillary rise infiltration in silica nanoparticle packings with average pore radii ranging from ∼1 to ∼9 nm. Using in situ ellipsometry and the Lucas–Washburn model, we discover a previously unknown inverse relationship between effective viscosity (ηeff) and average pore radius (Rpore). Additonally, we determine that PE transport under these extreme conditions is primarily governed by physical confinement, rather than pore surface chemistry. We refine an existing theory to provide a generalized formalism to describe the polymer transport dynamics over a wide range of pore radii (from 1 nm and larger). Our results offer valuable insights for optimizing catalyst supports in polymer upcycling and improving infiltration processes for nanocomposite fabrication.

Published: January 2024

The Blumlein pulse forming network (PFN) has widely been used in pulsed power technology to generate square waves with short pulse widths. In this paper, we developed a repetitive frequency square wave generator based on Blumlein PFN and pseudospark switch (PSS). A Blumlein PFN with unequal capacitances has been proposed, and the PFN parameters have been optimized for better output waveforms. A single-gap PSS with a withstand voltage of 40 kV and a repetitive frequency of 100 Hz has been designed to switch the Blumlein PFN. The experiment results show that the square wave generator can output pulses with a voltage of 26 kV, a rise time of 25 ns, and a pulse width of 90 ns on a matched load of 11 Ω. It has operated steadily for 10 h with a repetitive frequency of 100 Hz, and the jitter remains at around 1 ns after 1.05 × 106 shots.
Conceptions of the make-up of a human person in Ewe
Authors: Ameka Felix K. 
Published: January 2024

Abstract
Humans everywhere construct ethnopsychological models of
a person which involves a physical body and non-physical aspects. There is
variation in how the non-physical parts of a person are construed.
Invariably, it is assumed that this other part is “invisible inside” (Goddard, 2018, p. 168; Levisen, 2017; Peeters, 2019a). The
question of what the components of a human person in African culture(s) are
has been discussed, and debated in the literature (see e.g., Cotzee &
Roux, 2004). In this paper, I examine the conceptual model of a person in
Ewe communities of practice in West Africa through the prism of language and
the meanings of the terms for the ethnopsychological constructs of a
person.
Perception and expression of color among the Wolof of Senegal
Authors: Sall Adjaratou Oumar 
Published: January 2024

Abstract
The analysis and description of color terms has
re-emerged at the center of discussions in contemporary
anthropological linguistic research (based on well-established previous
studies over the past decades). However, work on color terms is still
lacking in most West African linguistic research, particularly in Senegal.
Wolof, a lingua franca spoken mainly in Senegal, has three basic colors used
with adverbs that are never used in other contexts, namely
ñuul ‘black’, ñuul kukk ‘extremely
black’, weex ‘white’, weex tàll ‘extremely
white’, xonq ‘red’ and xonq coyy
‘extremely red’, around which gravitate other shades of color whose terms
are taken from the surrounding vocabulary. The aim of this chapter is first
to present the color concepts and their “shades” in Wolof and to discuss the
question of the morphosyntactic encoding of color terms in linguistic
constructions. We will also consider their classification on the basis of
their semantic properties and occurrence in idiomatic expressions. Finally,
we will show how the community identifies itself through colors and what
symbolic representations of colors exist in the Wolof-speaking
community.
The narrative of a witness
Authors: Rüsch Maren 
Published: January 2024

Abstract
On a regular basis, the news and other shows and
documentaries on East African television feature various stories not only
about events in politics and society, but also of personal fates related to
them. In addition to the presenters, citizens of East African countries
share their perspectives on how they experienced events. This paper focuses
on the way in which these speakers tell their stories on a Kenyan TV show.
It will show how the common ritual oral tradition in Swahili, also
well-established in everyday conversation, is recontextualized in the media
and therefore brought from the ritual frame to the digital context, where it
is supposed to fulfill a particular purpose in favor of the TV program.
Therefore, the presenters instrumentalize the narratives’ inherent
linguistic practices applied by their witnesses to engage viewers in their
program.
Assessing the potential of using a virtual Veselago lens in quantitative microwave imaging
Authors: Eini Keleshteri Marzieh , Okhmatovski Vladimir , Jeffrey Ian , Bevacqua Martina Teresa , LoVetri Joe 
Published: January 2024

Abstract
This study explores the potential of implementing the focusing properties of a virtual ideal Veselago lens within a standard free-space microwave imaging scenario. To achieve this, the virtual lens is introduced as an inhomogeneous numerical background for the inverse source problem. This numerical Vesealgo lens is incorporated into the incident and scattered field decomposition, resulting in a new data equation that involves the Veselago lens Green’s function. In addition to the contrast sources within the object-of-interest, the lens introduces virtual contrast sources along the lens boundaries that depend on the total tangential magnetic field. It is shown that a surface integral contribution that takes into account these surface contrast sources must be added to the collected free-space data before one can invert using the well-conditioned Veselago lens inversion operator. A preliminary investigation of the accuracy to which this surface integral contribution must be computed is performed using additive Gaussian noise. Results show that an error of less than one percent is required to achieve imaging performance similar to utilizing an actual Veselago lens. All results are performed within a 2D simulation environment.
On inertial iterated Tikhonov methods for solving ill-posed problems
Authors: Rabelo J C , Leitão A , Madureira A L 
Published: January 2024

Abstract
In this manuscript we propose and analyze an implicit two-point type method (or inertial method) for obtaining stable approximate solutions to linear ill-posed operator equations. The method is based on the iterated Tikhonov (iT) scheme. We establish convergence for exact data, and stability and semi-convergence for noisy data. Regarding numerical experiments we consider: (i) a 2D inverse potential problem, (ii) an image deblurring problem; the computational efficiency of the method is compared with standard implementations of the iT method.
A novel epidemiologically informed particle filter for assessing epidemic phenomena. Application to the monkeypox outbreak of 2022
Authors: Papageorgiou Vasileios E , Kolias Pavlos 
Published: January 2024

Abstract
Contagious diseases are constantly affecting more and more people every day, resulting in widespread health crises especially in developing nations. Previous studies have developed deterministic and stochastic mathematical models to investigate the spread of epidemics. In the present study, a hybrid particle filtering epidemiological model is proposed, which combines the elements of a deterministic susceptible-exposed-infectious-recovered-deceased model with the inclusion of stochastic and penalty factors, in order to efficiently evaluate the dynamics of the disease. The inclusion of penalty factors stands out as the main novelty of the proposed methodology, guaranteeing estimations that align with the unique aspects of the examined natural phenomenon. The model is applied to the monkeypox data of the United States from 25 June to 21 November 2022. Our approach is compared to four alternatives, corresponding to deterministic and stochastic approaches that are associated with either fixed or time-varying parameters. In all cases, the particle filtering models displayed better characteristics in terms of infectious cases and deaths compared to their deterministic counterpart. The final version of the proposed epidemiologically informed particle filtering model exhibited significant potential and provided the best fitting/predictive performance compared to other examined methodologies. The predictive effectiveness of the proposed methodology has been thoroughly evaluated across various time intervals. Moreover, the inclusion of additional penalty factors in the weight computation procedure, assists in reducing fitting and prediction errors while simultaneously providing increased likelihood estimates. This modeling approach can be readily applied to other epidemics, both existing and emerging, where uncertainties in system dynamics and real-time observations hinder the accurate capture of the epidemic’s progression.
Prospects and challenges for all-optical thermal management of fiber lasers
Authors: Ballato John , Dragic Peter D , Digonnet Michel J F 
Published: January 2024

Abstract
It is hard to overstate the utility of lasers in modern technology. Optical-fiber-based lasers are of particular value thanks to their combination of small form factors, afforded by the coilability of the thin strands of fiber, and high beam-quality output. The optical fiber geometry also possesses a relatively high surface-area-to-volume ratio, rendering thermal management somewhat more straightforward than in other bulk laser types. Regardless, the generation of heat during the lasing process can still be problematic for a myriad of reasons, and conventional methods of thermal management do not comport with the potential compactness and elegance of fiber lasers as technological solutions. This Perspective summarizes recent advances in glass science and optical fiber engineering to support the provocative premise that heat generation in future laser systems can be entirely managed by a combination of fiber materials and novel laser physics. Letting the fiber manage heat itself would have significant impacts on enhancing system performance while greatly reducing size, weight, power-consumption, and cost.
Deep learning assisted pressure measurements using femtosecond laser-induced grating scattering technique

Published: January 2024

Abstract
The femtosecond laser-induced grating scattering (fs-LIGS) technique has recently been developed and applied for temperature and pressure measurements. In this work, we combined deep learning with the fs-LIGS technique to predict the gas-phase pressure from raw signals without data post-processing. Two deep learning models, a fully connected neural network and a convolutional neural network, were trained to master the hidden relationship between the features of the raw signal traces and the corresponding pressure under which the signal was recorded. Accurate pressure predictions by both models were achieved as mean percentage errors in model-predicted pressures compared to actual values within −4%–2%. These results suggest the feasibility of combining the deep-learning concept with the fs-LIGS technique for instantaneous pressure determination. Given the proper training of the models, this strategy could be extended to the simultaneous measurement of multiple thermodynamic quantities in real-time combustion and reacting flow diagnostics.
Time-varying digital coding of induced-magnetism Huygens’ metasurfaces for flexible and continuous control of harmonics
Authors: Zhu Hongyu , Qiu Chunqiao , Li Feng , Wu Chao , Liao Leng , Zhang Zhengren 
Published: January 2024

Abstract
Time-varying digital coding metasurfaces have garnered significant attention due to their ability to achieve flexible and continuous control over harmonics through the flexible design of coding sequences. These metasurfaces have important applications in wireless communications, radar detection, and biomonitoring. However, the majority of existing time-varying digital coding metasurfaces are reflective in design, leading to an inevitable masking effect at the location of the feed source. Therefore, there is an urgent need to explore the design of transmissive time-varying digital coding metasurfaces that enable flexible and continuous control of harmonics. In this study, we propose a transmissive time-varying digital coding metasurface based on the induced-magnetism Huygens’ principle. We conduct a detailed study of the phase modulation theory for flexible and continuous control of harmonics in the time-varying digital coding induced-magnetism Huygens’ metasurface. By precisely modulating the transmission phase difference of this metasurface and introducing time-delay gradients in each column of metasurface units, we achieve flexible and continuous control over harmonics successfully. Our study presents a solution for the design of transmissive time-varying digital coding metasurfaces, enabling flexible and continuous control over harmonics and expanding the application potential of time-varying metasurfaces.
