Introduction: The autologous conchal cartilage of good elasticity is easy to harvest, thus is often used in nasal tip plasty of East Asians. However, the operation techniques vary a lot among different surgeons. This article aims to introduce 3 techniques commonly used in clinical practice.
Methods: One hundred three patients were included in this study and divided into 3 groups according to the shape of the nasal tip during 2017 to 2019. The patients were followed up for at least 6 months. All patients were measured with Standardized Cosmesis and Health Nasal Outcomes Survey (SCHNOS). ImageJ software was used to measure and calculate the projection ratio for lateral position standard image, and columella-labial angle (CLA) was measured.
Results: In group 1, SCHNOS for nasal obstruction (SCHNOS-O) score were 13.23 ± 7.61 and 14.49 ± 10.55 (P > 0.05); SCHNOS for nasal cosmesis (SCHNOS-C) score were 66.55 ± 31.23 and 21.73 ± 18.91 (P < 0.001); projection ratio were 0.51 ± 0.04 and 0.57 ± 0.05 (P < 0.001); CLA were 91.02° ± 5.67° and 93.55° ± 4.64° (P > 0.05), preoperative and postoperative, respectively. In group 2, SCHNOS-O score were 16.76 ± 13.44 and 15.44 ± 9.26 (P > 0.05); SCHNOS-C score were 61.87 ± 44.14 and 19.16 ± 29.37 (P < 0.001); projection ratio were 0.50 ± 0.05 and 0.58 ± 0.03 (P < 0.001); CLA were 92.32° ± 6.39° and 94.86° ± 5.96°(P > 0.05), preoperative and postoperative, respectively. In group 3, SCHNOS-O score were 15.25 ± 7.83 and 17.73 ± 11.66 (P > 0.05); SCHNOS-C score were 52.03 ± 33.38 and 17.73 ± 11.66 (P < 0.001); projection ratio were 0.53 ± 0.05 and 0.57 ± 0.02 (P < 0.001); CLA were 91.65° ± 5.75° and 93.21° ± 5.38° (P > 0.05), preoperational and postoperational, respectively.
Conclusions: None of these 3 techniques cause or aggravate nasal obstruction, and all of them can achieve high cosmetic satisfaction. Technique 1 and technique 2 are suitable for the patients with moderate and moderate to severe short nose that is common in East Asia, which can better increase the protrusion of the tip and length of the nose. Technique 3 is suitable for the patients with better shape of the nose, who need to slightly increase the protrusion of the nasal tip and increase the upward rotation.

Snakebite envenoming is a neglected tropical disease that affects mainly rural populations, where antivenom is scarce. Understanding environmental drivers of snakebite incidence is critical for public health preparedness. This study employs causal inference to assess the impact of rainfall on snakebite surges in Colombia, with broader implications for tropical regions.

The distribution of particle radioactivity and the radioactive distribution are described by modeling the stabilized nuclear cloud. In addition, a three-dimensional radiation calculation module and a radionuclide calculation module are constructed based on the vertical diffusion theory of radioactive materials and the radionuclide fractionation model.

Objective: This study aimed to investigate the long-term effects of different suture and graft techniques on postoperative projection and rotation.
Methods: A total of 392 patients who met the inclusion criteria were screened and divided into 9 groups based on the technique performed. Outcome scores, tip projection ratios, and tip rotation angles were measured for the preoperative, early postoperative, and late postoperative periods.

Ultra-fast charging stations (UFCS) present a significant challenge due to their high power demand and reliance on grid electricity. This paper proposes an optimization framework that integrates deep learning-based solar forecasting with a Genetic Algorithm (GA) for optimal sizing of photovoltaic (PV) and battery energy storage systems (BESS). A Gated Recurrent Unit (GRU) model is employed to forecast PV output, while the GA maximizes the Net Present Value (NPV) by selecting optimal PV and BESS sizes tailored to weekday and weekend demand profiles.

In temperate regions, respiratory viruses such as SARS-CoV-2 are better transmitted in winter than in summer. Understanding how the weather is associated with SARS-CoV-2 transmissibility can enhance projections of COVID-19 incidence and improve estimation of the effectiveness of control measures. During the pandemic, transmissibility was tracked by the reproduction number .
