Authors: Idisi Park Odojoma , Dirisu Ibrahim Herbert , Adewale Funke , Bandele Masud Abdulafiz , Olufemitan Michael Olarewaju 
Published: October 2023

Based on existing theories, it is generally assumed that monetary policy can be used to regulate inflationary pressures. However, considering the numerous empirical studies that have taken place so far, conflicting evidence is inherent hence the essence of this study is to analyze this conflicting evidence with the aim of finding out the extent to which monetary policy by the Central Bank of Nigeria (CBN) has actually abated inflation in the country considering the continuous increase in the general price level of goods and services. The investigation relied on previous studies on the subject matter where it was revealed that though monetary policy particularly Open Market Operations (OMO) as a monetary Policy Tool is chief amongst the tools used in controlling inflation in Nigeria, it has really not been very effective. In the end, several recommendations were made accordingly, and the most important and urgent among them is the need for the government to put in more deliberate efforts in controlling imported inflation since Nigeria is an import-oriented nation particularly importation of refined crude, raw materials, industrial and agro-machinery and equipment, manufactured products, agro-allied products etc.

Published: October 2023

This article concerns the existence of multiple solutions of the polyharmonic system involving critical nonlinearities with sign-changing weight functions $$\displaylines{ (-\Delta)^mu = \lambda f(x) |u|^{r-2}u+ \frac{\beta}{\beta+\gamma} h(x) |u|^{\beta-2}u |v|^{\gamma}\quad \text{in }\Omega,\cr (-\Delta)^mv = \mu g(x) |v|^{r-2}v+ \frac{\gamma}{\beta+\gamma} h(x) |u|^{\beta} |v|^{\gamma-2} v \quad \text{in }\Omega, \cr D^ku=D^kv=0\quad \text{for all }|k|\leq m-1\quad \text{on }\partial\Omega, }$$ where \((-\Delta)^m\) denotes the polyharmonic operators, \(\Omega\) is a bounded domain in \(\mathbb{R}^N\) with smooth boundary \(\partial \Omega\), \(m\in \mathbb N\), \(N\geq {2m+1}\), \(1<r<2\) and \(\beta>1\), \(\gamma>1\) satisfying \(2<\beta+\gamma\leq 2_{m}^{*}\) with \(2_{m}^{*}=\frac{2N}{N-2m}\) as a critical Sobolev exponent and \(\lambda\), \(\mu>0\). The functions f, g and \(h:\overline{\Omega}\to \mathbb R\) are sign-changing weight functions satisfying f, \(g\in L^{\alpha}(\Omega)\) and \(h\in L^{\infty}(\Omega)\) respectively. Using the variational methods and Nehari manifold, we prove that the system admits at least two nontrivial solutions with respect to parameter \((\lambda, \mu)\in \mathbb R^2_{+} \setminus \{(0, 0)\}\).

Enhancing prediction of tooth caries using significant features and multi-model classifier
Authors: Alsubai Shtwai 
Published: October 2023

Background
Tooth decay, also known as dental caries, is a common oral health problem that requires early diagnosis and treatment to prevent further complications. It is a chronic disease that causes the gradual breakdown of the tooth’s hard tissues, primarily due to the interaction of bacteria and dietary sugars.

Results
While numerous investigations have focused on addressing this issue using image-based datasets, the outcomes have revealed limitations in their effectiveness. In a novel approach, this study focuses on feature-based datasets, coupled with the strategic integration of Principle Component Analysis (PCA) and Chi-square (chi2) for robust feature engineering. In the proposed model, features are generated using PCA, utilizing a voting classifier ensemble consisting of Extreme Gradient Boosting (XGB), Random Forest (RF), and Extra Trees Classifier (ETC) algorithms.

Discussion
Extensive experiments were conducted to compare the proposed approach with the chi2 features and machine learning models to evaluate its efficacy for tooth caries detection. The results showed that the proposed voting classifier using PCA features outperformed the other approaches, achieving an accuracy, precision, recall, and F1 score of 97.36%, 96.14%, 96.84%, and 96.65%, respectively.

Conclusion
The study demonstrates that the utilization of feature-based datasets and PCA-based feature engineering, along with a voting classifier ensemble, significantly improves tooth caries detection accuracy compared to image-based approaches. The achieved high accuracy, precision, recall, and F1 score emphasize the potential of the proposed model for effective dental caries detection. This study provides new insights into the potential of innovative methodologies to improve dental healthcare by evaluating their effectiveness in addressing prevalent oral health issues.
The impact of core self-evaluation on school adaptation of high school students after their return to school during the COVID-19 pandemic: the parallel mediation of positive and negative coping styles
Authors: Wang Qinglin , Duan Ruirui , Han Fulei , Huang Beibei , Wang Wei , Wang Qiulin 
Published: October 2023

Background
To explore the direct effect of core self-evaluation and the indirect effects of positive and negative coping styles on school adaptation of high school students after their return to school during the COVID-19 pandemic.

Methods
The Core Self-Evaluation Scale, Simple Coping Style Scale, and School Adaptation Questionnaire were used for the psychometric analysis of 500 high school students (229 males and 271 females) one month after their return to school. The bootstrap method was applied for mediation analysis.

Results
A positive correlation was noted between core self-evaluation and school adaptation (r = 0.56), and the predictive effect was significant (β = 0.43). Core self-evaluation positively predicted positive coping styles, which positively predicted school adaptation, while core self-evaluation negatively predicted negative coping styles, which negatively predicted school adaptation. Positive and negative coping styles played a significant mediating role between core self-evaluation and school adaptation. The mediating effect included the indirect effects generated by two pathways: core self-evaluation → positive coping style → school adaptation (95% CI [0.08–0.19]) and core self-evaluation → negative coping style → school adaptation (95% CI [0.03–0.11]).

Conclusion
There is a positive association between the core self-evaluation and school adaptation of high school students after their return to school during the COVID-19 pandemic. It may directly or indirectly affect the school adaptation of high school students after their return to school through positive or negative coping styles. After returning to school, educators should guide students to view themselves positively, cultivate healthy core self-evaluation, and enable them to have good school adaptation.
An exploration of the evidence surrounding the identity of the last captive Thylacine
Authors: Linnard Gareth , Sleightholme Stephen R. 
Published: October 2023

ABSTRACT
The last known captive Thylacine (Thylacinus cynocephalus) died at the Beaumaris Zoo on Hobart’s Queen’s Domain on the evening of Monday the 7th September 1936. However, within six months of its death the date of its capture was being inaccurately reported. Over the ensuing years there has been much debate and controversy relating to its source, sex, period of display, welfare, and more recently the fate of its remains. Whilst there has been some agreement, significant confusion has been created by the disparate, fragmentary, and often contradictory sources of evidence, with five distinctly exclusive provenances proposed for this specimen. For a species whose extinction was hastened by anthropogenic interventions, we have a moral obligation to preserve as much factual detail as possible about the Thylacine. To this end, the authors have undertaken a thorough review of the hypotheses advanced by Smith (1981) & Paddle (2000); Guiler (1986) & Bailey (2001); Sleightholme et al., 2020; Linnard et al., 2020 and Paddle & Medlock (2023), and have evaluated each against a synthesis of the evidence accrued over the previous 93 years to examine whether a definitive identification and history of the last known captive Thylacine can be determined. The authors found a sufficiently strong correlation between the evidence and the position advanced by Linnard et al., (2020) to maintain that the last captive Thylacine can be identified as the juvenile male captured at Penney’s Flats on the Arthur River by 19 year old Roy and 59 year old Dan Delphin on the evening of Monday 7th July 1930.

Published: October 2023

Oyster mushroom is an edible, saprophytic, and lignocellulolytic fungi. The folic acid present in oyster mushrooms helps to cure anemia. Oyster mushroom contains most of the mineral salts necessary for the human body. The amount of niacin is almost ten times higher than that of any other vegetables.
In this study, oyster mushroom (Pleurotus ostreatus var. florida (Jacq: Fr) Kummer) were grown with various substrate additions to determine their effects on yield. We ran tests to know different supplements affected the yield and growth of mushrooms. The substrate, composed primarily of sawdust and straw, served as the growth medium. The research encompassed controlled environmental conditions, including temperature, humidity, and light, over a defined study period. Our findings revealed significant variations in mushroom yield and growth parameters across the different supplement treatments. The best supplements to the substrate treatment combination were observed T14- Wheat Straw (60%), + Rice Straw (34 %) + Gram Flour (2% of the substrate) (451.69g) and (452.33g) followed by T11 – Rice Straw (60%), + Wheat Straw (34 %) + Maize Flour (2% of the substrate) which increased the yield of oyster mushroom, while others exhibited nuanced effects on mushroom quality. Statistical analyses supported these observations. The implications of this research extend to both commercial and amateur mushroom cultivators. Understanding the influence of substrate supplements on Oyster mushroom growth can lead to more efficient and cost-effective cultivation practices. By optimizing substrate composition, growers can enhance yields, potentially increasing profitability and sustainability in the mushroom industry. This study also highlights the need for further exploration in the field, including investigations into the specific mechanisms underlying supplement-substrate interactions.

Authors: Oyeyemi Dare Azeez , Ojo Adebola K. 
Published: October 2023

In the modern era, mobile phones have become ubiquitous, and Short Message Service (SMS) has grown to become a multi-million-dollar service due to the widespread adoption of mobile devices and the millions of people who use SMS daily. However, SMS spam has also become a pervasive problem that endangers users' privacy and security through phishing and fraud. Despite numerous spam filtering techniques, there is still a need for a more effective solution to address this problem [1]. This research addresses the pervasive issue of SMS spam, which poses threats to users' privacy and security. Despite existing spam filtering techniques, the high false-positive rate persists as a challenge. The study introduces a novel approach utilizing Natural Language Processing (NLP) and machine learning models, particularly BERT (Bidirectional Encoder Representations from Transformers), for SMS spam detection and classification. Data preprocessing techniques, such as stop word removal and tokenization, are applied, along with feature extraction using BERT.
Machine learning models, including SVM, Logistic Regression, Naive Bayes, Gradient Boosting, and Random Forest, are integrated with BERT for differentiating spam from ham messages. Evaluation results revealed that the Naïve Bayes classifier + BERT model achieves the highest accuracy at 97.31% with the fastest execution time of 0.3 seconds on the test dataset. This approach demonstrates a notable enhancement in spam detection efficiency and a low false-positive rate.
The developed model presents a valuable solution to combat SMS spam, ensuring faster and more accurate detection. This model not only safeguards users' privacy but also assists network providers in effectively identifying and blocking SMS spam messages.

AbstractObjectiveTo characterize structural integrity of the lumbosacral enlargement and conus medullaris within one month after spinal cord injury (SCI).MethodsLumbosacral cord MRI data were acquired in patients with sudden onset (<7 days) SCI at the cervical or thoracic level approximately one month after injury and in healthy controls. Tissue integrity and loss were evaluated through diffusion tensor (DTI) and T2*‐weighted imaging (cross‐sectional area [CSA] measurements). Associations with the degree of neurological impairment were assessed using linear mixed‐effects models.ResultsTwenty‐one patients with SCI showed lower white matter (WM) fractional anisotropy (FA) (≤−13.3%) and higher WM radial diffusivity (≤14.6%) compared to 27 healthy controls. Differences were most pronounced in the lateral columns of WM. CSA measurements revealed no group differences. For the lateral columns, lower FA values were associated with lower motor scores and lower amplitudes of motor evoked potentials. For the dorsal columns, lower FA values were associated with lower amplitudes of somatosensory evoked potentials from the lower extremities.InterpretationOne month after SCI, first signs of WM degeneration were apparent, without indication of tissue loss. The more pronounced differences observed in the lateral column could be attributed to anterograde degeneration of the motor tracts. The variability among DTI measurements remote from the lesion site can be partially explained by the degree of the SCI‐induced neurological impairment. Together with previous studies, our findings indicate that impaired tissue integrity precedes tissue loss. The presented techniques have potential applications in monitoring the progression of various neurological diseases.

Published: January 2025

AbstractTensile ductility is one of the key concerns in the field of flexible devices. Ag2Te is a promising flexible thermoelectric (TE) material due to its high TE properties and compressive ductility, but low tensile ductility blocks its flexible application. In this work, a low‐dimensional strategy is adopted to find that Ag2Te nanowires exhibit an exceptional tensile fracture strain of 75.7% at room temperature, several times higher than other ceramic and semiconductor nanowires, and even comparable to some metals. By in situ transmission electron microscope (TEM) observations and density functional theory (DFT) calculations, the tensile ductile mechanism has been successfully revealed. First, the emissions of partial dislocations from the surface lead to the slipping band along (100) plane, which is attributed to the atomic rearrangement along (100) plane. Then, the surface steps occur, and deformation twinning forms along (001) plane at the slip region, which inhibits the crack initiation. Finally, Ag particles precipitate around the slip region and then form Ag nanobridges to further resist the external deformation, achieving extraordinary tensile ductility. This work provides some insights into the mechanical behaviors of Ag2Te at the nanoscales, which is beneficial for the development of reliable micro‐devices.

AbstractNitric oxide (NO) is an essential molecule in biomedicine, recognized for its antibacterial properties, neuronal modulation, and use in inhalation therapies. The effectiveness of NO‐based treatments relies on precise control of NO concentrations tailored to specific therapeutic needs. Electrochemical generation of NO (E‐NOgen) via nitrite (NO2–) reduction offers a scalable and efficient route for controlled NO production, while also addressing environmental concerns by reducing NO2– pollution and maintaining nitrogen cycle balance. Recent developments in catalysts and E‐NOgen devices have propelled NO2– conversion, enabling on‐demand NO production. This review provides an overview of NO2− reduction pathways, with a focus on cutting‐edge Fe/Cu‐based E‐NOgen catalysts, and explores the development of E‐NOgen devices for biomedical use. Challenges and future directions for advancing E‐NOgen technologies are also discussed.

AbstractNoise‐induced hearing loss (NIHL) results from prolonged exposure to intense noise, causing damage to sensory outer hair cells (OHCs) and spiral ganglion neurons (SGNs). The blood labyrinth barrier (BLB) hinders systemic drug delivery to the inner ear. This study applied a retro‐auricular round window membrane (RWM) method to bypass the BLB, enabling the transport of macromolecular proteins into the inner ear. Pigment epithelium‐derived factor (PEDF), which has anti‐inflammatory and neuroprotective properties, is conjugated to a prestin‐targeting peptide 2 (PrTP2) using N‐succinimidyl‐3‐maleimidopropionate (SMP) to form PrTP2‐SMP/PEDF. This compound specifically targeted Prestin and accumulated around OHCs for sustained release, effectively reducing OHC and SGN loss. Functional and structural tests, including auditory brainstem response (ABR), confocal microscopy, and scanning electron microscopy (SEM), revealed significant hearing restoration and cellular protection. Additionally, the results of enzyme‐linked immunosorbent assay (ELISA), Annexin V and propidium iodide (PI) staining and immunoblotting show that noise exposure may induce pyroptosis in the cochlea by activating the NOD‐like receptor protein 3 (NLRP3)‐apoptosis‐associated speck‐like protein containing a CARD (ASC) – cysteinyl aspartate specific proteinase (Caspase‐1) pathway and PrTP2‐SMP/PEDF alleviates the inflammatory response by inhibiting pyroptosis. Toxicity analysis indicates no adverse effects, suggesting that PrTP2‐SMP/PEDF has a promising therapeutic prospective for NIHL.
From X‐ To J‐Aggregation: Subtly Managing Intermolecular Interactions for Superior Phototheranostics with Precise 1064 nm Excitation

Published: January 2025

AbstractThe stacking mode in aggregate state results from a delicate balance of supramolecular interactions, which closely affects the optoelectronic properties of organic π‐conjugated systems. Then, managing these interactions is crucial for advancing phototheranostics, yet remains challenging. A subtle strategy involving peripheral phenyl groups is debuted herein to transform X‐aggregated SQ‐H into J‐aggregated SQ‐Ph, reorienting intermolecular dipole interactions while rationally modulating π–π interactions. Co‐assembled with liposomes (DSPE‐PEG2000), SQ‐Ph nanoparticles (NPs) exhibit low toxicity, superior biocompatibility, and a bathochromic shift to the 1064 nm match‐excited NIR‐II region, with a fluorescence brightness (ε1064 nm ΦNIR‐II) of 4129 M−1 cm−1 and a photothermal conversion efficiency (PCE) of 48.3%. Preliminary in vivo experiments demonstrate that SQ‐Ph NPs achieve a signal‐to‐background ratio (SBR) of up to 14.29 in NIR‐II fluorescence imaging (FLI), enabling highly efficient photothermal therapy (PTT) of tumors guided by combined photoacoustic imaging (PAI). This study not only enriches the J‐aggregation library but also provides a paradigm for optimizing photosensitizers at the supramolecular level.
