Authors: Horwitz Matthew A. 
Published: August 2024

AbstractDiscovery Process Chemistry (DPC) is an emerging intersectoral space that is characterized by the development of new chemical reactions or syntheses that enable the efficient elucidation of structure-activity relationships (SARs) and structure-property relationships (SPRs) as well as a rapid transition to process development. Drug discovery and development are accelerated by such efforts and this has led chemists in academia and industry alike to place an increasing importance on these aims. In this Short Review, we explore recent advances in DPC and the impact that it can have on SAR/SPR interrogation and downstream drug development efforts.1	Introduction2	Enabling SAR/SPR Interrogation with Bioisosteres3	Couplings of Diversifiable Reaction Partners4	Late-Stage Functionalization5	Conclusion and Outlook

Published: August 2024

Abstract
Objectives The aim of this study was to translate and validate the condition-specific Oral Health Impact Profile (OHIP) in the Croatian cultural context and assess the impact of periodontal diseases and nonsurgical periodontal therapy on quality of life (QoL).
Materials and Methods A cross-sectional study was carried out on 150 individuals: 50 periodontally healthy, 50 with gingivitis, and 50 with periodontitis who self-administrated the OHIP. The participants' age ranged between 18 and 71 years, with the median age of 45 (34–57) years. Forty-seven percent of the participants were females. The validity and reliability of the Croatian OHIP version were tested. The impact of gingivitis and periodontitis on QoL was assessed. Changes in QoL induced by nonsurgical periodontal therapy in 20 patients with periodontitis were analyzed.
Statistical Analysis Categorical data were presented by absolute and relative frequencies. The normality of the distribution of continuous variables was tested by the Shapiro–Wilk test. Continuous data were described by the median and the limits of the interquartile range (IQR). Differences in continuous variables between two independent groups were tested with the Mann–Whitney U test, and between three groups with the Kruskal–Wallis test (post hoc Conover). The Wilcoxon signed-rank test was used to examine the differences in the total score before and after therapy. All p values were two-sided. The level of significance was set at alpha of 0.05.
Results The analysis detected a single-factor structure that explained for the 56.9% of the variance. Cronbach's alpha value was 0.937, which indicated an excellent internal consistency. Overall OHIP score reported a strong correlation with the subjective estimate of periodontal problems (Rho = 0.92; p < 0.001). Test–retest reliability was high (r = 0.984; p < 0.001). The periodontitis group had the highest OHIP score (28 [23–34]), followed by the gingivitis group (14 [12–20]) and the periodontally healthy group (9 [5–11]; p < 0.001). Nonsurgical periodontal therapy significantly improved the QoL in those with periodontitis (p < 0.001).
Conclusion The condition-specific Croatian version of the OHIP instrument can be considered adequate to measure the impact of periodontal diseases on oral health–related QoL. Periodontal diseases, especially periodontitis, have a negative effect on the patient's QoL. Nonsurgical periodontal treatment can improve patients' QoL.

Published: August 2024

AbstractBiliary complications following liver transplantations, in the form of bile leak and bile duct strictures, are well recognized. Portobiliary fistulas in the transplant setting are rare, but may cause potentially life-threatening complications. The presented case shows the successful treatment of a hilar portobiliary fistula in a transplanted liver posthepaticojejunostomy with portal vein stent graft followed by biliary drainage with percutaneous hepaticojejunostomy stricture dilatation.

Published: August 2024

Abstract
Background Distal radius fractures are extremely common. Most of them can be treated conservatively, but there are still many controversies about this nonoperative treatment. The purpose of this study was to assess whether the pain experienced during distal radius fracture reduction using the hematoma block plus a nerve block at the wrist is less than the perceived pain using an isolated hematoma block and whether the success of the closed reduction remains at least the same.
Methods A total of 192 patients were included in a comparative study to assess whether the pain experienced during wrist fracture reduction using the hematoma block plus a nerve block at the wrist was less than using an isolated hematoma block and whether they were equally effective.
Results The mean Visual Analog Scale (VAS) for pain at the wrist was 4.6 in the hematoma plus nerve block and 5.1 in the isolated hematoma block. The score at the fingers was 5.2 in the hematoma plus nerve block and 7.3 in the hematoma block. The success of the procedure was the same among groups.
Conclusions The hematoma plus nerve block is more effective than the isolated hematoma block in reducing the pain during wrist fracture reduction, especially for fingers pain. The mean VAS was far from ideal and further focused research can be very useful because of the great clinical impact it can have.

Cardiac Arrest during Temporary Clipping for Ruptured Internal Carotid Artery Aneurysm: A Case Report
Authors: Shimizu Toshihiko , Kosaka Hiroshi , Yamamoto Yuji 
Published: August 2024

AbstractMechanical stimulation of the trigeminal nerve during craniofacial, skull base, or dental surgeries may cause bradycardia, hypotension, or cardiac arrest. This phenomenon is called trigeminal cardiac reflex (TCR). We encountered a rare case of a patient who experienced sinus arrest due to temporary clipping of the intracranial carotid artery during the clipping of a ruptured aneurysm. We discuss possible reasons for the occurrence of TCR in this case. A man in his 30s with no medical history presented with a sudden-onset headache. Computed tomography revealed a subarachnoid hemorrhage in the basal cistern and left Sylvian fissure. Angiography revealed a saccular aneurysm of the left internal carotid-anterior choroidal artery. A left frontotemporal craniotomy and dural incision were performed, followed by a trans-Sylvian approach. Cardiac arrest occurred twice during the temporary clipping of the intracranial carotid artery. After surgery, we performed a cardiac ultrasound echo and a 1-week Holter electrocardiogram. Neither showed abnormalities. No arrhythmia or cardiac events were observed over a one and half-year follow-up period. The cardiac arrest might have been triggered by the stimulation of the trigeminal nerve in the internal carotid artery. The repeated and anatomical features of this case suggest that TCR triggered cardiac arrest. The high probability that cardiac arrest was induced by trigeminal nerve stimulation should be considered during the temporary clipping of the internal carotid artery. However, the predisposing factors and exact underlying mechanisms for these arrhythmias remain unknown and require further investigation.
Impact of risk factors on the link between natural resources rents and carbon emissions: Evidence from economic, financial, and political risks
Authors: Wang Qiang , Zhang Siqi , Li Rongrong 
Published: August 2024

AbstractEffective management of natural resources is crucial for diminishing carbon emissions. This research explores how economic, financial, and political risks influence the relationship between natural resources rents and carbon emissions. Analyzing data from 66 countries, this study utilizes methods such as quantile regression and dynamic threshold regression to thoroughly assess the data. The findings reveal: (i) Natural resources rents tend to increase carbon emissions consistently across different quantiles (0.1 to 0.9). The fact is confirmed by robustness checks, illustrating that increased natural resources rents lead to higher emissions. (ii) Economic, financial, and political risks affect how natural resources rents impact carbon emissions. Notably, reduced economic and financial risks lessen the propensity of natural resources rents to boost emissions at higher quantiles, while a decline in political risk decreases the exacerbating effect of natural resources rents on emissions from the 0.1 to 0.9 quantiles. (iii) This analysis uncovers threshold effects where economic, financial, and political risks act as threshold factors. Specifically, when economic and political risks are low, a rise in natural resources rents actually leads to a decline in carbon emissions. The findings underscore the importance of considering these risks in the formulation of policies aimed at reducing carbon emissions from natural resource exploitation.
Some coordinates for mapping a literary translation activism
Authors: Washbourne Kelly 
Published: August 2024

Abstract
Translation and activism have been closely linked in the scholarly discourse. It is hard to parse out, however, the goals and contours of a specifically literary translation activism (LTA), particularly as it may intersect with literary activism, literary advocacy, and other forms of praxis. What constitutes an act of literary translation activism? And what forms are literary translation activism taking, and how does a text become activist? The answers have implications for literary translators’ self-concept, agency, and identity construction as well as the ethics involved. LTA is manifested in prizegiving, framing, choice of language, adapting, choosing texts (or even refusing translation), translation strategy, memorializing, heightening status, ‘reinventing’ literary affiliation, and changemaking or awareness-raising for extraliterary causes. After taking stock of some of literary translation activism’s forms and even caveats, I draw some paths for a pedagogy of LTA, which can play a constitutive role in drawing the field’s boundaries.
Educational technology, higher education discourses and the lived experience of lecturers as users
Authors: Bailey Richard 
Published: August 2024

Abstract
Technological innovations, under the aegis of ‘technology-enhanced learning’ (TEL), are high on policy agenda in
higher education institutions (HEIs) in the UK and elsewhere. These developments have a direct impact on the conditions of
teaching and learning. The socio-cultural dimension – the impact of change on working communities and their practices and beliefs
on the ground – appears under-researched in empirical work (Selwyn, 2022). This paper
reports on a qualitative study incorporating an analysis of linguistic metaphors that attempted to investigate that gap in one
institutional context.
It begins with a critical review of metaphors associated with policy and educational technology innovation in
education discourses more broadly. Teaching staff were interviewed from across the institution’s main faculties. The interview
transcripts formed a databank of naturally occurring language. Respondents used a range of metaphors, both conventional and novel,
revealing insights into the affective and sociocultural dimensions of experience and understanding as well as perceptions of
changing professional roles. For triangulation, linguistic analyses of relevant documentary sources, where available, were made
and an example is included here. Overall, a more nuanced understanding of lecturers’ lived experience and engagement with
educational technology was achieved by focusing on their metaphor usage.
Thrust of a pulsed plasma jet measured from deviations of a ballistic pendulum
Authors: Scurtu A , Ticoș D , Udrea N , Mitu M L , Ticoș C M 
Published: August 2024

Abstract
We measured the peak force of the plasma jet produced by a pulsed coaxial plasma gun operated at voltages up to 2 kV, using a home-made ballistic pendulum positioned in two locations, one in the proximity of the gun nozzle at 0.75 cm and the second at a distance of 9 cm from the gun nozzle. The force of the plasma wind is inferred and ranges from 11 to 60 N, which is almost an order of magnitude higher than that of typical ion-based thrusters. The results of various models of self-field magneto-plasmadynamic thrusters indicate that the magnetic component thrust tends to dominate over the thermal expansion, particularly at higher discharge voltages of 1.5 kV and 2 kV. The highest thrust of 60 N is obtained for a 2 kV discharging voltage. The plasma was ignited in CO2 at pressures between 1 and 5 Torr. The displacement of the pendulum pushed by the plasma wind force was measured using a high-speed camera.
Optimal control for nonlinear time-fractional Schrödinger equation: an application to quantum optics
Authors: Vijayaram S , Balasubramaniam P 
Published: August 2024

Abstract
In this research article, a fractional optimal control problem (FOCP) is applied to a nonlinear time-fractional Schrödinger equation (NTFSE) incorporating a trapping potential. The NTFSE is an innovative mathematical advancement in the field of quantum optics, bridging fractional calculus with nonlinear quantum mechanics and addressing the intricacies of systems involving memory and nonlinearity. This exploration helps with potential technological advancements in quantum optics and related domains. Examining the FOCP within this system allows one to design quantum optical systems with enhanced performance, improved precision stability, and robustness against disturbances. In this work, the performance index for the problem is constructed, and then it is reformulated using the fractional variational principle and the Lagrange multiplier method. Additionally, the Jacobi collocation numerical method is employed to solve the FOCP and numerical simulations are demonstrated across various parameters which offer valuable insights into the implemented methodology.
A novel plaintext-related image encryption and compression method based on a new coupled map lattices model
Authors: Li Zhen , Yang Siqi , Tan Weijie , Huang Zhi , Wang Jiakun 
Published: August 2024

Abstract
In this paper, we propose a new Sine-Logistic Map Coupled Map Lattices (SLMCML) model, which exhibits enhanced chaotic characteristics and more suitable for image encryption compared with the classical coupled map lattices. Based on the SLMCML system, we propose an image encryption and compression method. To improve the plaintext sensitivity of image cryptosystem, we propose a novel plaintext-related internal keys generation method, which can obviously improve the plaintext sensitivity of initial values of SLMCML system, thus improve the plaintext sensitivity of whole process of compression and encryption. Our proposed image encryption scheme contains several steps. Initially, the discrete wavelet transform (DWT) is utilized to convert original image into coefficient matrix. Then a plaintext relation method is constructed, which generate internal keys as initial values of SLMCML system. Next the coefficient matrix is permutated by permutation sequences generated by SLMCML system to cyclic shift for making the energy evenly distributed. Next the coefficient matrix is done sparse processing. The compressed sensing is employed to compress coefficient matrix. Subsequently, the compressive image is permutated with spiral traversal and twice zigzag transform. Finally, the permutated image is diffused with column diffusion to generate cipher image. Through some common security analyses, our proposed image encryption scheme has good security performance and excellent image recovery quality.
Circuit modelling and validating a capacitively loaded implantable antenna with its sensitivity analysis for biomedical applications
Authors: Kaur Sukhpreet , Kaur Jaswinder , Khanna Rajesh 
Published: August 2024

Abstract
This paper presents a flexible and capacitively loaded implantable antenna with its sensitivity analysis for biomedical applications. The proposed antenna is designed to operate within the ISM (Industrial, Scientific, and Medical) band, which ranges from 2.4 to 2.48 GHz. The overall dimensions of an antenna are 8 × 8 × 0.25 mm3. The substrate material FR-4 is utilised with a dielectric constant (ε
r) 4.4, loss tangent (δ) 0.0022 and a thickness of 0.25 mm for the proposed antenna. An ultra-flexible superstrate material, Parylene C, is used with a thickness of 40 microns on both sides of an antenna to avoid direct contact of metallization with human tissue. Further, the proposed antenna is initially implanted inside a four-layer cubic (FLC) phantom, and then its parameters are validated using the CST Hugo voxel model. The simulated bandwidth of an antenna is 28.16 %, whereas measured bandwidths are 32.25 % inside the tissue-mimicking phantom and 64 % inside minced pork. Moreover, assessing the specific absorption rate (SAR) in a realistic model ensures patient safety by following the guidelines outlined in C95.1–1999 for 1g and 10g of tissue. The simulated and measured results are in close agreement, making the designed antenna appropriate for biomedical applications.
Dynamic potential stochastic resonance for weak signal detection
Authors: Zong Ping , An Ran , Wang Hongyu , He Jiaming , Zhang Chi 
Published: August 2024

Abstract
To suppress the low-frequency interference noise, a dynamic potential stochastic resonance (DPSR) model is proposed in this paper for weak signal detection. The DPSR model introduces a single dynamic parameter k that simplifies parameter optimization. Its dynamic potential function can adaptively adjust to match noisy input signals. This model provides a new nonlinear model for triggering the SR phenomenon. Experimental results indicate that compared to the traditional methods that rely on clear interference frequency distributions to filter low-frequency components directly, the SR model offers greater flexibility and convenience. Unlike classical SR models, the proposed DPSR model demonstrates a 1.5 dB improvement in output performance for suppressing low-frequency interference. Therefore, the DPSR model not only robustly suppresses interference but also effectively enhances and detects characteristic signals in variant-noise environments. Application to sea trial signals highlights the superior performance of the DPSR model in significantly reducing low-frequency interference and improving target signal recognizability compared to other models.
Non-Gaussianity consistency relations and their consequences for the peaks
Authors: Namjoo Mohammad Hossein , Nikbakht Bahar 
Published: August 2024

Abstract
Strong deviations from scale invariance and the appearance of high peaks in the primordial power spectrum have been extensively studied for generating primordial black holes (PBHs) or gravitational waves (GWs). It is also well-known that the effect of non-linearities can be significant in both phenomena. In this paper, we advocate the existence of a general single-field consistency relation that relates the amplitude of non-Gaussianity in the squeezed limit f
NL to the power spectrum and remains valid when almost all other consistency relations are violated. In particular, it is suitable for studying scenarios where scale invariance is strongly violated.
We discuss the general and model-independent consequences of the consistency relation on the behavior of f
NL at different scales.
Specifically, we study the size, sign and slope of f
NL at the scales where the power spectrum peaks and argue that generally the peaks of f
NL and the power spectrum occur at different scales.
As an implication of our results, we argue that non-linearities can shift or extend the range of scales responsible for the production of PBHs or GWs, relative to the window as determined by the largest peak of the power spectrum, and may also open up new windows for both phenomena.
Application of drone technology in power grid engineering

Published: August 2024

Abstract
With the dynamic adjustments in eco-control zones, spatial layouts can be further optimized, but this has brought some challenges to the planning and construction of power grid projects. Utilizing drones and related technologies, it is possible to conduct surveys of eco-control zones with clear boundaries and unclear boundaries, which is beneficial for early risk avoidance in power grid projects. The results indicate that the use of orthophoto and oblique photography can effectively measure the boundaries of control areas and classify the ecological types within the research area. Maximizing the use of drone surveying technology can effectively identify control area boundaries, but attention must be paid to the factors affecting drone operations to prevent excessive measurement errors and reduce the accuracy of control area identification.
