Authors: Abid Abyaz , Azad A. K. , Bhuiyan Arafat A. 
Published: October 2023

AbstractThis research paper investigates the optimization of radiation performance of a plasma-based bioconvective nanofluid integrated Magneto-hydrodynamic (MHD) micropump for radiative oncology. It addresses a literature gap by analysing the radiative impact of blood-based hybrid nanofluids in MHD micropumps. Three blood-based bio-convective radiating hybrid nanofluids—blood—Pt, blood—Au and blood—MWCNT are studied to understand their radiation behaviour in MHD pump while being employed as transportation medium. The investigation employs two non-dimensional parameters, namely Rd (Radiation number) and Ha (Hartmann number), to examine the fluid dynamics, magnetic characteristics, and electrical properties of the MHD micropump. The temperature gradient, velocity distribution, and pressure drop along the flow channel are examined within the specified range of Rd and Ha. Magnetic flux density (MFD) and electric flux intensity (EFI) are evaluated to understand nanoparticle behaviour during drug delivery and blood transportation. Findings highlight that MWCNT and Pt are the most efficient bioconvective nanoparticles for plasma transportation under high radiative conditions. MWCNT-based blood flow exhibits desirable characteristics, including sufficient intake pressure of 4.5 kPa and minimal relative pressure drop of 34%. Coherence between radiation flux and electromagnetic flux reduces pumping power and ensures uniform heat dissipation for improved drug delivery. Au nanoparticles provide moderate magnetic flux density with least fluctuation within the range of Ha and Rd number (2.57 T to 4.39 T), even in highly radiative environments (such as—Rd = 4, Rd = 5), making them suitable for applications like embedded chemotherapy or cell treatment. Au nanoparticles maintain moderate electrical flux intensity with a minimal drop of 16nA, particularly at higher radiative environments influenced by the Radiation number (Rd = 4 to Rd = 5) while Ha values from Ha = 2 to Ha = 4. Conclusively, it has been identified that MWCNT and Au are superior nanofluids for advanced radiative oncological treatments. These nanofluids have the potential to enhance plasma transportation, thermal regulation, and aetilogical disease management. The present study provides significant findings on enhancing the radiation performance in MHD micropumps through utilization of blood-based hybrid nanofluids, thereby offering potential advantages to the domain of biomedical engineering.

Published: October 2023

AbstractA new practical imaging technique was presented for metamaterial characterization and investigation by visualizations of the magnetic microwave near-field (H-MWNF) distributions on a metamaterial's surface using the method of thermo-elastic optical indicator microscopy (TEOIM). ITO-based transparent and ceramic-based opaque metamaterial structures were designed for magnetic near-field visualization. Depending on the incident microwave field polarization, the TEOIM system allows the characterization of the metamaterial properties and microwave interaction behavior. The working principle of the periodic structures was investigated through numerical simulations, and the obtained results exhibited strong agreement when compared with experimental observations. Moreover, the visualization of the H-MWNF revealed the potential to characterize and evaluate the absorption and transmission properties effectively.

AbstractTo investigate the effects and potential mechanisms of human umbilical cord mesenchymal stem cells, exosomes, and their conditioned media on lipid storage in oleic acid (OA) and palmitic acid (PA) treated hepatocytes and high-fat methionine- choline deficient diet (HFMRCD) induced non-alcoholic steatohepatitis (NASH) mice. AML12 cells were stimulated with OA and PA to establish the lipid storage cell model. HucMSCs, exosomes, and culture medium were then co-cultured. At the same time, C57BL/6 mice were fed an HFMRCD for 6 or 8 weeks to establish a NASH mouse model. The effect of HucMSCs, exosomes, and culture medium on lipid droplet repair of hepatocytes or NASH mice was then assessed. The weight of hepatocytes or liver tissue, Oil Red O, hematoxylin–eosin staining, Masson staining, Western blot, and qPCR were used to detect the related IL-6, TNF-α, TGF-β1 andEI24/AMPK/mTOR pathway expression in hepatocytes and liver tissue. Compared with the model group, the effect of HucMSCs-Ex on inhibiting the accumulation of lipid droplets was more obvious at the cell level. In vivo study showed that HucMSCs-Ex reduces activity scores in NASH mice and improves liver tissue morphology by reducing vacuolar degeneration, fat deposition, and collagen deposition of liver tissue. Western blot and qPCR results showed that inflammatory factors and AMPK/mTOR or EI24-related autophagy pathways were altered before and after treatment. HucMSCs, HucMSC-Ex, and CM can promote autophagy in hepatocytes or NASH mice through the AMPK/mTOR or EI24-related autophagy pathway and alleviate injury associated with lipid deposition, collagen deposition or inflammation, reversing the progression of NASH.
Enhancement of plasmonic coupling on Si metallized with intense femtosecond laser pulses
Authors: Tateda Mika , Iida Yuto , Miyaji Godai 
Published: October 2023

AbstractUsing a pump–probe technique, the reflectivity of a silicon grating surface irradiated with intense femtosecond (fs) laser pulses was measured as a function of the incidence angle and the delay time between pulses. After irradiating the surface with an intense s-polarized, 400 nm, 300 fs laser pulse, the reflectivity measured with a weak p-polarized, 800 nm, 100 fs laser pulse exhibited an abrupt decrease for an incidence angle of ~ 24°. The depth of the dip was greatest for a delay time of 0.6–10 ps, for which the reflectivity around the dip was highest. The surface was also found to be ablated most strongly for the conditions causing the deepest dip for a delay time of 5–10 ps. Surface plasmon polaritons (SPPs) on silicon metallized by the intense pulse are resonantly excited by the subsequent pulse, and the strong coherent coupling between the subsequent pulse and SPPs excited on the molten Si surface produced by high-density free electrons induces strong surface ablation due to the intense plasmonic near-field. The results clearly show that fs pulses can be used to significantly modulate the nature of nonmetallic materials and could possibly serve as a basic tool for the excitation of SPPs on nonmetallic materials using ultrafast laser–matter interactions.

Purpose:
The purpose of this study was to systematically review the research literature with regards to treatments and intervention methods for hereditary hearing loss. Our goal was to provide reference guidelines for the rational use of medication and gene-targeted therapy for patients with hereditary hearing loss and discuss the future development of research in this area.

Method:
We searched two core databases, PubMed and Web of Science, for relevant literature relating to potential treatments and interventional methods for hereditary hearing loss. Then, we used Microsoft Excel to perform basic statistical analysis of the data, the R language to perform bibliometric analyses, and VOSviewer and CiteSpace to visualize data. In addition, we clustered and descriptively analyzed the data and identified the relative importance of each approach with regard to precise patient outcomes.

Results:
In this study, we followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standardized screening process and identified a total of 103 research articles. The average annual growth rate of publications in this area was 12.73%. The country with the highest number of publications and citations was the United States; 80 of these publications (associated with 76.92% of funding) were supported by grants from 16 countries. Potential treatments and interventions were clustered according to the stage of research and showed that 8.74% remain in the research design stage, 59.22% are in the clinical validation stage, and 32.04% are being applied in the clinic. The main research focus in this field is cochlear implants and gene therapy.

Conclusions:
Hereditary hearing loss is in a critical period of transition from preventive to therapeutic research. Gene-targeted interventions represent one of the most promising and effective treatments.

Biosynthesis, targeting and processing of oleosin‐like proteins, which are major pollen coat components in Brassica napus
Authors: Murphy Denis J. , Ross Joanne H. E. 
Published: October 2023

SummaryThe purpose of this study is to characterise the biosynthesis, targeting and processing of some of the major protein components of the pollen coat, or tryphine, of Brassica napus. The authors have N‐terminally sequenced 11 of the most abundant pollen coat polypeptides, and nine of these sequences correspond to proteolytically cleaved products of seven oleosin‐like genes, i.e. Oln B;1 to Oln B;6 and Oln B;11. The Oln B;11 gene product is co‐ or post‐translationally targeted in vitro to canine microsomal membranes. This implies that the oleosin‐like protein is targeted to the endoplasmic reticulum in tapetal cells in vivo. Affinity‐purified antibodies raised against a 20‐residue domain of Oln B;3 and B;4 gene products cross‐reacted with full‐length proteins of 45–48 kDa in early developing (< 2 mm to 5 mm) buds and anthers, but recognised truncated proteins of 32–38 kDa at later (4 mm to 7 mm) stages of development. The 45–48 kDa immunoreactive proteins were associated with a floating lipid body fraction obtained from a tapetal/locular fluid extract from maturing anthers and a major 48 kDa polypeptide from this fraction was confirmed by N‐terminal sequencing to be a full length product of the Oln B;3 gene. Quantitative immunocytochemical studies showed that the full length 45–48 kDa oleosin‐like proteins were specifically localised in the interior of tapetal cytoplasmic lipid bodies where they were associated with a regular hexagonal‐like fibrous reticulum. No significant labelling of elaioplasts was observed. The same antibodies specifically labelled 32–38 kDa oleosin‐like proteins on the extracellular pollen coat of maturing pollen grains. These results demonstrate for the first time that many of the major pollen coat proteins are derived from an endoproteolytic cleavage of precursor oleosin‐like proteins that originally accumulate within the large cytoplasmic lipid bodies of tapetal cells.

Context. Dust in active galactic nuclei is clearly present right outside the broad-line region (BLR) in the form of a dusty molecular torus. However, some models of the BLR predict that dust may also exist within the BLR.
Aims. We study the reprocessing of radiation by the BLR with the aim of observing how the presence of dust affects the reprocessed continuum and the line properties.
Methods. We calculated a range of models using the CLOUDY photoionisation code for dusty and dustless plasma. We paid particular attention to the well-studied object NGC 5548, and we compared the line equivalent width predictions with the data from observations for this object.
Results. We obtained a rough agreement between the expected equivalent widths of the Hβ and Mg II lines and the observed values for NGC 5548 for the line distances implied by the time-delay measurement (for Hβ) and the radius-luminosity relation (for Mg II) when the medium is dusty. We found the incident radiation to be consistent with the radiation seen by the observer, so no shielding between the inner disc and the BLR is required. High ionisation lines such as He II, however, clearly form in the inner dustless region. When the additional absorber is present, the Hβ emitting region moves closer to the dustless part of the accretion disc surface.
Hitherto Unreported Pattern of Complex Obstructive Partial Anomalous Pulmonary Venous Drainage with Dual Drainage of Accessory Pulmonary Veins
Authors: Garg Dollphy , Sharma Arun , Naganur Sanjeev Hanumantacharya , Singhal Manphool 
Published: October 2023

AbstractPartial anomalous pulmonary venous drainage is a congenital cardiac disorder characterized by abnormal drainage of one or more pulmonary veins into the systemic circulation. It can be isolated or associated with other congenital cardiac anomalies, most commonly atrial septal defect and patent ductus arteriosus. The clinical presentation is variable and depends on the degree of shunting and associated cardiac anomalies. Many patients usually remain asymptomatic until late in life. In this article, we presented a complex case of obstructive partial anomalous pulmonary venous drainage with dual drainage of bilateral accessory pulmonary veins with intact interatrial septum in conjunction with a patent ductus arteriosus and a ventricular septal defect. This pattern is incredibly rare and to the best of our knowledge has not been previously reported. Computed tomography played a pivotal role in precisely elucidating the intricate anatomy in this case with a complex pattern of anomalous pulmonary venous drainage.
Intuition as a “trained thing”: sensing, thinking, and speculating in computational cultures
Authors: Pedwell Carolyn 
Published: October 2023

AbstractWhat happens when intuition becomes algorithmic? This article explores how approaching intuition as recursively trained sheds light on what is at stake affectively, politically, and ethically in the entanglements of sensorial, cognitive, computational and corporate processes and (infra)structures that characterise algorithmic life. Bringing affect theory and speculative philosophies to bear on computational histories and cultures, I tease out the continuing implications of post-war efforts to make intuition a measurable and indexable mode of anticipatory knowledge. If digital computing pioneers tended to elide the more ambivalent implications of quantifying intuition, this article asks what computational myths are at play in current accounts of machine learning-enabled sensing, thinking, and speculating and what complexities or chaos are disavowed. I argue that an understanding of more-than-human intuition which grapples meaningfully with the indeterminacy central to digitally mediated social life must recognise that visceral response is recursively trained in multiple ways with diverse, and often contradictory, effects.
Semiotic landscape in a green capital
Authors: Kosatica Maida 
Published: October 2023

Abstract
In the wake of the ‘climate apocalypse’ global discourse, the environmental agenda of the European Green Deal and
the overarching objective for the European Union are to deliver a high level of protection and improvement of the quality of the
environment. European cities are under pressure to reinvent urban environments and develop resilience to environmental risks. This
paper looks at semiotic material appearing in Essen, a city in Germany awarded the European Green Capital title. Grounded in the
multimodal social semiotic approach and ecolinguistics, the paper investigates strategically emplaced ‘green’ semiotic material
which shape environmental values and privilege. The paper illustrates the political economy of city clean-ups which every so often
result in questionable environmental choices and fail to alleviate social inequalities. The analysis ultimately shows how semiotic
forms of sustainability are evidently implicated in the creation of urban eco-arenas accentuating the socioeconomic stratification
and privileges of valorized places.

Published: October 2023

Abstract
Digital signal processing is a valuable practical skill for the contemporary physicist, yet in physics curricula, its central concepts are often introduced either in method courses in a highly abstract and mathematics-oriented manner or in lab work with little explicit attention. In this paper, we present an experimental task in which we focus on a practical implementation of the discrete Fourier transform (DFT) in an everyday context of vibration analysis using data collected by a smartphone accelerometer. Students are accompanied in the experiment by a Jupyter Notebook Companion, which serves as an interactive instruction sheet and a tool for data analysis. The task is suitable for beyond-first-year university physics students with some prior experience in uncertainty analysis, data representation, and data analysis. Based on our observations the experiment is very engaging. Students have consistently reported interest in the experiment and they have found it a good demonstration of the DFT method.
Born and inverse Born series for scattering problems with Kerr nonlinearities
Authors: DeFilippis Nicholas , Moskow Shari , Schotland John C 
Published: October 2023

Abstract
We consider the Born and inverse Born series for scalar waves with a cubic nonlinearity of Kerr type. We find a recursive formula for the operators in the Born series and prove their boundedness. This result gives conditions which guarantee convergence of the Born series, and subsequently yields conditions which guarantee convergence of the inverse Born series. We also use fixed point theory to give alternate explicit conditions for convergence of the Born series. We illustrate our results with numerical experiments.

Published: October 2023

Abstract
Low-threshold, narrow linewidth phonon lasers can greatly improve the detection resolution of sensors and have enormous potential for development in classical and quantum sensing fields, as well as information processing. However, its development is limited due to unfavorable factors such as the complex process, low quality factor (Q-factor), difficult tuning, and harsh environments requirements. Here, we report an easy-to-excite phonon laser with an ultra-narrow linewidth in silica whispering gallery mode microsphere optomechanical resonators at room temperature and ambient pressure. The microsphere cavity is fabricated by high-temperature melting with a CO2 laser and designed by controlling the proportion of the sphere to the stem (sphere-to-stem ratio) to reduce mechanical damping. By using a single-frequency laser as the pump source, the microsphere optomechanical resonator exhibited multiple breathing mode phonon lasers with ultra-high optical Q-factor (1.78 × 109), mechanical Q-factor (3.1 × 107), and low threshold (2.4 μW). It is the first time to achieve such a high mechanical Q-factor in the microsphere cavity system of this kind to the best of our knowledge, which opens up an avenue to develop highly sensitive sensors.
Near-infrared switch effect of polarization modulation induced by guided-mode resonance in dielectric grating

Published: October 2023

Abstract
Light intensity modulation is crucial for the development of optical imaging, optical sensing, and optical switch. Light intensity modulation methods, such as changing structural parameters, external temperature, or external voltage, make the control process time consuming and complex. The plasmonic polarization modulation is an effective strategy to modulate the light intensity, but this method is limited by the excitation of surface plasmons with transverse magnetic (TM) polarized light. Herein, we report another polarization modulation method for light intensity based on guided mode resonance in a dielectric grating excited by transverse electric (TE) polarized light. The nanosystem comprises a Si grating and a TiN substrate. By adjusting the polarization states of the incident light from TE to TM, the proposed nanosystem exhibits an outstanding light intensity modulation performance with a relative modulation depth of 25833%. The presented method provides another way for modulating the light intensity, which has potential applications in optical switching, optical imaging, and optical anti-counterfeiting.
Optimizing silver nanowire dimensions by the modification of polyol synthesis for the fabrication of transparent conducting films
Authors: Thomas Neethu , Sharma Neha , Swaminathan Parasuraman 
Published: October 2023

Abstract
Transparent conducting films (TCFs) made by the assembly/deposition of silver nanowires (Ag NWs) are widely used to manufacture flexible electronics such as touch screens, heaters, displays, and organic light-emitting diodes. Controlling the dimensions (length and diameter) of the nanowires is key in obtaining TCFs with the desired optoelectronic properties, namely sheet resistance and optical transparency. This work describes a combined experimental and theoretical investigation on the optimization of the NW dimensions to fabricate high-quality TCFs. Ag NWs of different dimensions are synthesized by the modified polyol method and the average diameter and length of the wires are tailored over a wide range, 35–150 nm and 12–130 μm respectively, by controlling the synthesis parameters such as reaction conditions, stabilizing agents, and growth promoters. The synthesized NWs are spin coated on glass substrates to form TCFs. Comparing the films with different lengths, but identical diameters, enabled the quantification of the effect of length on the optoelectronic properties of the TCFs. Similarly, the effect of NW diameter is also studied. A non-uniformity factor is defined to evaluate the uniformity of the TCF and the transmittance of the NW network is shown to be inversely proportional to its area coverage. The sheet conductance versus the normalized number density is plotted for the different concentrations of NWs to extract a conductivity exponent that agrees well with the theoretical predictions. For thin film networks, the relation between the transmittance and sheet resistance provides the percolative figure of merit (FoM) as a fitting parameter. A large FoM is desirable for a good-performing TCF and the synthesis conditions to achieve this are optimized.
