As an analog of intersection graphs among digraphs, catch digraphs were introduced by Hiroshi Maehara in 1984. Later on, Prisner focused his research on interval catch digraphs, which he identified as diasteroidal triple free digraphs. It has been used to solve a variety of real-world challenges, such as networking, telecommunication operations, traffic control, and location problems. Oriented catch digraphs are those catch digraphs that have exactly one edge direction attached to each edge of the corresponding underlying graph. In this article, we consider two important subclasses of oriented catch digraphs, namely, oriented interval catch digraphs and oriented circular-arc catch digraphs. First, we characterize those oriented interval catch digraphs whose underlying graphs are trees in terms of forbidden subdigraphs. Next, we provide a characterization of connected proper oriented interval catch digraphs whose underlying graphs are chordal, by determining the complete list of forbidden induced subdigraphs. Another interesting result is characterizing oriented circular-arc catch digraphs, which are tournaments.

The distribution of wind-driven rain on building facades significantly affects their thermal performance and durability. Accurately and efficiently predicting the wind-driven rain catch ratio on wall surfaces is crucial for building performance evaluation. This study proposes a novel computational approach to rapidly predict the wind-driven rain catch ratio on urban building facades. A predictive model was developed using extensive numerical simulations combined with machine learning algorithms. Specifically, the model replaces traditional numerical simulations by learning the influence of wind field characteristics and building geometry on raindrop catch ratios across different sizes. The research results indicate that the machine learning models can effectively substitute conventional simulation methods for wind-driven rain predictions. Notably, the Artificial Neural Network model achieved a prediction accuracy comparable to numerical simulations (RMSE: 0.009, MAE: 0.006) while being over 300 times faster. The inlet wind speed at roof height emerged as the most influential feature, and the model exhibited strong generalization performance across varying wind directions. This method is simple, efficient, and well-suited to support wind-driven rain analysis, experimental measurements, and urban energy consumption studies in residential building contexts.

Purpose To investigate the effect of studying abroad on catch-up vaccination coverage for measles, rubella, mumps, varicella, and tetanus during the pretravel consultation among young adult travelers.Methods This retrospective cohort study analyzed data from the Japan Pretravel Consultation Registry (J-PRECOR) on individuals aged 18–21 years with childhood vaccination records. Propensity score weighting was used to estimate the average treatment effect on the proportion of participants receiving catch-up vaccination.Results Among 1091 eligible participants, the catch-up vaccination need was highest for mumps (65.7 %) and varicella (49.0 %) and lowest for measles (9.9 %) and rubella (14.0 %). In the unadjusted analysis, the catch-up vaccination rate was 70.6 % for tetanus, 50.9 % for measles, 47.7 % for rubella, 40.0 % for mumps, and 23.9 % for varicella. In the weighted analysis, the study-abroad group had significantly higher catch-up vaccination rates for measles (54.6 % vs. 29.8 %, P = 0.039), rubella (53.0 % vs. 22.1 %, P 

Introduction Despite its importance for young women, the human papillomavirus (HPV) vaccination coverage remains low in Japan. Previous studies have examined behaviors related to HPV catch-up vaccination. Uniquely, this study aimed to investigate perceptions and factors influencing vaccination coverage among female university students in the catch-up program, focusing on both medical and non-medical undergraduates.Methods A web-based survey was conducted at Kochi University from January 16 to February 13, 2023, targeting female students born between April 2, 1997, and April 1, 2006. The survey collected demographic data and assessed knowledge of HPV infection, cervical cancer, and preventive measures. Chi-square tests and logistic regression analyses were used to identify differences between vaccinated and unvaccinated groups as well as factors related to HPV vaccination.Results Of the 310 participants, 39.0 % were vaccinated against HPV, 35.2 % were freshmen, and 75.2 % were in medical science programs. HPV vaccination was significantly associated with being in upper years of university (OR = 3.78–42.83), studying medical sciences (OR = 1.93), undergoing cervical cancer screening (OR = 4.04), and receiving free vaccination vouchers (OR = 2.03).Conclusion Knowledge and awareness of HPV and cervical cancer significantly contribute to higher vaccination uptake in the generation receiving catch-up vaccinations. Tailoring information and distributing free vaccination vouchers could enhance HPV vaccination rates and awareness in this group.

Catch and release ice angling exposes fish to environments and techniques that differ markedly from those in the open-water season. Accordingly, we studied the influence of quick-strike treble hooks and 0º offset circle hooks on aspects of northern pike (Esox lucius) capture and behaviour using tip-ups during the winter. Based on 221 northern pike captured over three winters, quick strike rigs with multiple hooks had higher catch success, but extended dehooking time and caused more foul hooking. Deep hooking events were infrequent but were most likely to occur when pike were captured on the single treble quick strike rig and circle hook. Camera footage revealed that pike were tentative and appeared to require considerable time to strike. Hook style had no influence on fish behaviour when striking. Our findings suggest that the use of triple treble quick strike rigs may provide benefits to anglers because they hook more and slightly larger fish and do not result in deep-hooking events. Circle hooks caught in the jaw most frequently and were the easiest to remove most of the time; however, they periodically deep-hooked fish, which was unexpected. Ultimately, angler tackle choice will affect their enjoyment of ice angling, and the potential for stress and injury to fish when using tip ups.

Demersal trawl fisheries are increasingly challenged by new and more ambitious gear regulations alongside rising fuel costs. However, knowledge of behavioral differences between species are yet poorly integrated and exploited in commercially operated trawl designs. In the demersal mixed species trawl fishery for Nephrops (Nephrops norvegicus), many fish species are herded by the netting and actively avoid contact with the meshes as opposed to Nephrops, for which most individuals are tumbling along the bottom panel of the gear towards the codend. By reducing the mesh size of the entire lower half of the trawl we reduced the loss of marketable sized Nephrops through the bottom panels significantly by 47.2 % (CI: 33.6–60.2 %) in the North Sea. The unchanged catches of the round fish, cod (Gadus morhua) and hake (Merluccius merluccius) confirm that these species do not come in physical contact with the bottom panel. In contrast, witch flounder (Glyptocephalus cynoglossus) escapes through the bottom panel of the baseline trawl as the treatment gear caught 65.1 % (CI: 39.5–104.9 %) more marketable-sized individuals and 259.7 % (CI: 144.4–459.5 %) more undersized individuals. Our results confirm known species-specific behavior in the forward part of the trawl and demonstrate how this can be exploited with simple design changes to increase the catch efficiency for Nephrops and likely other species without affecting the catches of roundfish. The undersized individuals captured will largely escape through the meshes used in commercial codends.
