Authors: Lau Kirstie , Patel Shruti , Bryant Cathy , Sood Sanjeev 
Published: January 2024

Trauma to the primary dentition is a common occurrence affecting approximately 1 in 5 young children globally. Damage to the successor tooth may present as a localized enamel defect, dilaceration and disturbed eruption, with subsequent functional and social impact. Appropriate management of acute primary dental trauma, regular review and timely specialist referral upon detection of eruption sequence abnormalities is, therefore, imperative for long-term outcome to be optimal. This article presents a series of four case reports of paediatric patients with a history of severe primary dental trauma that resulted in significant dental anomalies requiring multidisciplinary treatment. CPD/Clinical Relevance: Information on the consequences of primary dental trauma and the advice to give to affected families is of value.

Published: January 2024

We demonstrate a Sagnac-interferometer-based multiwavelength fiber laser with an intensity-dependent loss (IDL) mechanism in the L-band region using a semiconductor optical amplifier (SOA) as the gain medium. The IDL mechanism flattens and stabilizes the multiwavelength spectrum. We also investigate the effect of rotation angles of polarization controllers (PCs) at different polarization devices on multiwavelength performance. At best settings, 31 lasing lines within 3 dB uniformity were generated with an extinction ratio (ER) of 17 dB. Adjusting the half-wave plate of PC1 and PC2 from 0° to 90° shifted the multiwavelength output by 0.01 nm and 0.072 nm, respectively. PC2 adjustment also affects the multiwavelength flatness as compared to PC1. Furthermore, the number of lasing lines and the ER were directly influenced by the SOA current.

Published: January 2024

The extraction of 3D human pose and body shape details from a single monocular image is a significant challenge in computer vision. Traditional methods use RGB images, but these are constrained by varying lighting and occlusions. However, cutting-edge developments in imaging technologies have introduced new techniques such as single-pixel imaging (SPI) that can surmount these hurdles. In the near-infrared spectrum, SPI demonstrates impressive capabilities in capturing a 3D human pose. This wavelength can penetrate clothing and is less influenced by lighting variations than visible light, thus providing a reliable means to accurately capture body shape and pose data, even in difficult settings. In this work, we explore the use of an SPI camera operating in the NIR with time-of-flight (TOF) at bands 850–1550 nm as a solution to detect humans in nighttime environments. The proposed system uses the vision transformers (ViT) model to detect and extract the characteristic features of humans for integration over a 3D body model SMPL-X through 3D body shape regression using deep learning. To evaluate the efficacy of NIR-SPI 3D image reconstruction, we constructed a laboratory scenario that simulates nighttime conditions, enabling us to test the feasibility of employing NIR-SPI as a vision sensor in outdoor environments. By assessing the results obtained from this setup, we aim to demonstrate the potential of NIR-SPI as an effective tool to detect humans in nighttime scenarios and capture their accurate 3D body pose and shape.

Published: January 2024

Aim
This retrospective cohort study aimed to evaluate the association between body weight and oral cGVHD (chronic graft versus host disease).

Methods
Patients with oral cGVHD were compared with an age and gender-matched non-GVHD cohort in terms of demographic information, body mass index (BMI), date of transplant, length of hospitalization, and oral complications. Weight was stratified in pre-and post-transplant weight, mean weight after acquiring cGVHD for the first year, and post-oral cGVHD BMI. Each patient was matched and compared with two controls at a 1:2 ratio. Firth’s penalized likelihood logistic regression was used to investigate the association between oral complications and weight loss greater than 5% in the oral cGVHD group.

Results
This study included 137 patients (n = 42 oral cGVHD, n = 12 non oral-cGVHD and n = 83 non-GVHD). The oral cGVHD cohort had a 1.44 times higher risk (RR) of being underweight (BMI<18.5 kg/m2) compared to the non-GVHD cohort. Oral mucositis was an independent predictor of weight loss above 5% in the oral cGVHD cohort (p < 0.001)

Conclusion
The weight loss was more prevalent among oral cGVHD, and oral mucositis was linked to significant weight loss. Weight loss may indicate the need to initiate early and aggressive symptomatic oral cGVHD treatment.

Published: January 2024

INTRODUCTION:
The aim of this study was to investigate the epigenetic regulation and underlying mechanism of NRIP3 in colorectal cancer (CRC).

METHODS:
Eight cell lines (SW480, SW620, DKO, LOVO, HT29, HCT116, DLD1, and RKO), 187 resected margin samples from colorectal cancer tissue, 146 cases with colorectal adenomatous polyps, and 308 colorectal cancer samples were used. Methylation-specific PCR, Western blotting, RNA interference assay, and a xenograft mouse model were used.

RESULTS:

NRIP3 exhibited methylation in 2.7% (5/187) of resected margin samples from colorectal cancer tissue, 32.2% (47/146) of colorectal adenomatous polyps, and 50.6% (156/308) of CRC samples, and the expression of NRIP3 was regulated by promoter region methylation. The methylation of NRIP3 was found to be significantly associated with late onset (at age 50 years or older), poor tumor differentiation, lymph node metastasis, and poor 5-year overall survival in CRC (all P < 0.05). In addition, NRIP3 methylation was an independent poor prognostic marker (P < 0.05). NRIP3 inhibited cell proliferation, colony formation, invasion, and migration, while induced G1/S arrest. NRIP3 suppressed CRC growth by inhibiting PI3K-AKT signaling both in vitro and in vivo. Methylation of NRIP3 sensitized CRC cells to combined PI3K and ATR/ATM inhibitors.

DISCUSSION:

NRIP3 was frequently methylated in both colorectal adenomatous polyps and CRC. The methylation of NRIP3 may potentially serve as an early detection, late-onset, and poor prognostic marker in CRC. NRIP3 is a potential tumor suppressor. NRIP3 methylation is a potential synthetic lethal marker for combined PI3K and ATR/ATM inhibitors.

Abstract
High-performance biochar was prepared using de-oiled Chlorella vulgaris biomass as the raw material and KOH as the modifying activator. The properties of the biochar as an adsorbent for the removal of tetracycline (TC) and enrofloxacin (ENR) were investigated under different conditions by varying the amount of the Chlorella vulgaris de-oiled biomass (DB) input. The surface structure and physicochemical properties of different Chlorella vulgaris biomass charcoal (CBC) samples were studied and compared, and the best adsorption performance of the biomass charcoal was obtained when DB = 7. Through orthogonal analysis, it was determined that the optimal adsorption condition of CBC 7 on TC was 0.004 g (pH 3), which resulted in a removal rate of 96.45% and a maximum adsorption capacity of 241.1363 mg g−1, and on ENR was 0.004 g (pH 7), which resulted in a removal rate of 100% and a maximum adsorption capacity of 256.3326 mg g−1. The results of the kinetic fitting show that the adsorption of TC and ENR by CBC 7 was consistent with the pseudo-secondary kinetic equation. The maximum adsorption capacities can reach 299.8974 and 352.6736 mg g−1. Langmuir and Freundlich adsorption isotherm models were used to describe the adsorption equilibrium of TC and ENR by CBC 7. The results show that the adsorption of TC and ENR are in accordance with the Langmuir isotherm.

Abstract
Transition metal dichalcogenide (TMDs) heterostructure, particularly the lateral heterostructure of two different TMDs, is gaining attention as ultrathin photonic devices based on the charge transfer (CT) excitons generated at the junction. However, the characteristics of the interface of the lateral heterostructure, determining the electronic band structure and alignment at the heterojunction region, have rarely been studied due to the limited spatial resolution of nondestructive analysis systems. In this study, we investigated the confined phonons resulting from the phonon-disorder scattering process involving multiple disorders at the lateral heterostructure interface of MoS2–WS2 to prove the consequences of disorder-mediated deformation in the band structure. Moreover, we directly observed variations in the metal composition of the multi-disordered nanoscale alloy Mo1−x

S2, consisting of atomic vacancies, crystal edges, and distinct nanocrystallites. Our findings through tip-enhanced Raman spectroscopy (TERS) imply that a tens of nanometer area of continuous TMDs alloy forms the multi-disordered interface of the lateral heterostructure. The results of this study could present the way for the evaluation of the TMDs lateral heterostructure for excitonic applications.
Development of a Methodical Framework to Calculate Rational Height of the Riser Strip in Pervious Concrete Pavement Construction

Published: January 2024

Abstract
Pervious concrete pavement (PCP) system is an emerging technology due to its sustainability and stormwater management capabilities. Globally, there is no standard procedure for the design and construction of PCPs. However, one empirical technique used during the field implementation encompasses the provision of 9–9 mm of riser strip for PCP surface course, as also suggested by the American Concrete Institute. To advance the PCP design toward a mechanistic approach, this paper provided a methodology to compute the rational height of the riser strip based on correlations between different properties of pervious concrete (PC) and the uncompacted PC mixture density. Additionally, a user-interactive program called “Pervious Concrete Pavement Construction Assistant Program (PCPCAP)” was also developed using MATLAB. Furthermore, the proposed methodology was evaluated by preparing small-scale test slabs in the laboratory and field with a target porosity of 34 %. Cores were extracted from the 7-day-cured slab and tested for porosity and hardened density. The results showed an excellent match between target and measured porosities with a difference of less than 3 %. Additionally, the calculated hardened density corresponding to the target porosity and the measured hardened density were also in good agreement, with a difference of only 3 %. It is noteworthy that the proposed framework will help during the construction of PCPs, conforming to the desired properties in an effective and practicable manner. Overall, it is envisioned that this first-of-its-kind methodical technique could be used by contractors and practitioners to enhance the quality of PCP construction as part of field implementation practices.
Study of the Influence of Sisal Fiber Length on Cement Emulsified Asphalt Mixture and Its Strengthening Mechanism
Authors: Hu Chao , Zhou Zhigang , Luo Yaoyao 
Published: January 2024

Abstract
In order to explore the suitable length of sisal fibers used in cement emulsified asphalt mixtures, this paper refers to the AC-20 gradation of hot mix asphalt mixture, and adds 3 mm, 6 mm, 9 mm, 12 mm, 15 mm, and 18 mm sisal fibers to cement emulsified asphalt mixture. The effects of different sisal fiber lengths on the performance of cement emulsified asphalt mixture were investigated by low temperature splitting tests, high temperature stability tests, and water stability tests. The influence of different fiber lengths on the performance of cement emulsified asphalt mixture was investigated by grey correlation theory. The results show that there is a correlation between the length of the sisal fiber and the performance of the cement emulsified asphalt mixture. The length of sisal fiber has the greatest influence on the splitting tensile strength of cement emulsified asphalt mixture, followed by dynamic stability, freeze-thaw splitting strength ratio, immersion Marshall residual stability, vacuum saturation residual stability, and permeability coefficient. The enhancement mechanism of sisal fiber on cement emulsified asphalt mixture was explored by means of infrared spectroscopy and electron microscope scanning. The results show that after adding sisal fiber to cement emulsified asphalt mixture, the overall stability of cement emulsified asphalt mixture is increased under the action of “pulling anchor” of sisal fiber. According to the research results of this paper, it is suggested that sisal fiber with a length of 9 mm is added to cement emulsified asphalt mixture under AC-20 gradation.

A través de cuatro ejemplos de poemarios construidos mediante écfrasis literaria, este artículo propone un acercamiento a las nuevas perspectivas críticas del género. Integran el estudio los libros La piel del vigilante (2005), de Raúl Quinto, Sistemas inestables (2015), de Rubén Martín, Descendimiento (2018), de Ada Salas y El bello mundo (2019), de Francisco Javier Navarro Prieto. El corpus seleccionado comparte, desde diferentes acercamientos intermediales, una misma temática —el cuerpo en dolor— y muestra una clara renovación de los códigos ecfrásticos. Si bien todos han sido publicados en el siglo XXI, cada poemario entabla diferentes diálogos de muy distinto signo con la obra artística original, por lo que ofrecen un amplio retrato panorámico de la écfrasis actual. Con ello se demuestra no solo la creciente vitalidad del género, sino también su relevancia y alcance en la última poesía española.

Authors: Jaenudin Ujam , Fitriah Elis Anisah , Devi Mirna 
Published: January 2024

Online identity frauds such as love scams, catfishing, and fake content are associated with the freedom of personalization offered by social media platforms which can lead to deceptive self-presentation behavior and impressions. Therefore, this research aimed to examine the role of motivation to use Instagram and the dark triad personality on deceptive self-presentation. It was conducted quantitatively through structural equation model (SEM) analysis based on partial least squares (PLS) using data collected from 400 early adult Instagram users between the ages of 20 and 34 years in Indonesia. The results showed that motivation to use Instagram and the dark triad personality influenced deceptive self-presentation by 30.9% on ideal self-dimension and 41.9% on false self-dimension. Moreover, motivational dimensions of gaining new friendships, following and monitoring, social connectedness and social recognition had a significant influence on deceptive self-presentation. In the dark triad personality variable, only the narcissism dimension was observed to have a significant influence on deceptive self-presentation.

Published: January 2024

The 0.9NiTiO3-0.1CoFe2O4 ceramic was prepared by sol-gel method. The structural and ferroelectric properties of the ceramic were investigated. Structure of the materials was analyzed by X-ray diffraction and scanning electron microscopy. Fabricated materials consists of NiTiO3 with rhombohedral phase structure and CoFe2O4 with cubic structure. The effect of sintering temperature and dwell time on the phase, microsctructure and ferroelectric properties of the ceramics was investigated. As the sintering temperature and dwell time increased, the density of the bulk sample was improved. The material sample was sintered at 1200oC for 10 h with large particle size (~6 µm), few pores and high density ~97.5%. The composite material displayed ferroelectric properties, as evidence from the characteristic hysteresis loop observed in ferroelectric materials. At sintering temperatures of 1000°C and 1100°C for 2 and 5 h, the sample exhibited poor ferroelectric characteristics. However, when the sample was sintered at 1200°C for 10 h, a notable enhancement in ferroelectric properties was observed.
