To assess the association between polymorphisms of the IL-6 -174 G/C and Behçet's disease (BD) in Tunisian patients. DNA was extracted from blood samples taken from 43 Tunisian patients and 43 healthy controls. The polymorphisms were analyzed by PCR with the PCR-RFLP. No significant association was found between patients and controls concerning polymorphism of IL6 -174 G/C between the (allelic frequency: C (17.44 vs 8, 13%; P=0.17) et G (82,55 vs 91,86%; P= 0.21).

Balancing the data before training a classifier is a popular technique to address the challenges of imbalanced binary classification in tabular data. Balancing is commonly achieved by duplication of minority samples or by generation of synthetic minority samples. While it is well known that balancing affects each classifier differently, most prior empirical studies did not include strong state-of-the-art (SOTA) classifiers as baselines. In this work, we are interested in understanding whether balancing is beneficial, particularly in the context of SOTA classifiers. Thus, we conduct extensive e

Available wearable dosimeters suffer from spectral mismatch during the measurement of broadband UV and visible radiation in environments that receive radiation from multiple sources emitting differing spectra. We observed this type of multi-spectra environment in all five Washington State cannabis farms visited during a field study investigating worker exposure to ultraviolet radiation in 2018. Spectroradiometers do not suffer from spectral mismatch in these environments, however, an extensive literature review conducted at the time of writing did not identify any spectroradiometers that were

The subject of the research focuses on identifying the differences between the three attempts to test the viability of VC and the contribution of age ratios, and some anthropometric measurements in the best bioenergy test. It also aims to adjust a regression model to predict the biological capacitance in relation to age and some anthropometric variables.

Despite limited success, information retrieval (IR) systems today are not intelligent or reliable. IR systems return poor search results when users formulate their information needs into incomplete or ambiguous queries (i.e., weak queries). Therefore, one of the main challenges in modern IR research is to provide consistent results across all queries by improving the performance on weak queries. However, existing IR approaches such as query expansion are not overly effective because they make little effort to analyze and exploit the meanings of the queries. Furthermore, word sense disambiguati

Introduction: Hypertrophic and keloid scars arise from abnormal healing processes in fibrous tissue where tissue repair and regeneration control mechanisms do not work well. The standard treatment is an intralesional steroid injection with triamcinolone acetonide (TA). This method is effective, but there are some side effects include hypopigmentation and tissue atrophy. The nanofat method has been applied to various skin conditions with fewer side effects. Therefore, the use of nanofat with its regenerative properties can be expected to yield better results.

The male and female birds were bred and reared in the farm till they reached maturity following which they were released to the wild. A mating pair was later formed and their territory established in the farm area. A decoy was used to simulate a natural intruder to the defended area.

In-context learning (ICL) has transformed the use of large language models (LLMs) for NLP tasks, enabling few-shot learning by conditioning on labeled examples without finetuning. Despite its effectiveness, ICL is prone to errors, especially for challenging examples. With the goal of improving the performance of ICL, we propose corrective in-context learning (CICL), an approach that incorporates a model's incorrect predictions alongside ground truth corrections into the prompt, aiming to enhance classification accuracy through self-correction.
