Background： Vulvody.ia, or vulvar pain, is a common condition in women; however, there are few evidence-based clinical trials evaluating nonpharmacological therapies for this condition. Acupuncture is one complementary.and integrative medicine therapy.used by.some patients with vulvody.ia. This study.evaluates two different acupuncture strategies for the treatment of vulvody.ia and aims to evalu- ate whether either of the acupuncture protocols reduces vulvar pain, pain duration or pain with inter- course. The study.also examines how long the effect of acupuncture lasts in women with vulvody.ia. Methods/design： The study.is designed as a randomized controlled trial, focused on two acupuncture protocols. fifty.one patients who have had vulvody.ia for more than 3 months will be recruited. Among them, 34 patients will be randomized into Groups la and 1b; those who are unwilling to receive acupuncture will be recruited into the standard care group （Group 2）. Patients in Group la will have acupuncture focused on the points in the pudendal nerve distribution area, while patients in Group lb will receive acupuncture focused on traditional （distal） meridian points. Patients in Group 2 will receive routine conventional treatments, such as using pain medications, local injections and phy.ical therapies or other nonsurgical procedures. Acupuncture will last 45 min per session, once or twice a week for 6 weeks. The primary.outcome measurement will be objective pain intensity. using the cotton swab test. The secondary.outcome measurement will be subjective patient self-reported pain intensity. which will be conducted before cotton swab test. Pain intensities will be measured by.an 11-point Numeric Pain Rating Scale. Pain duration and pain score during intercourse are recorded. Local muscle tension, tender- ness and trigger points （Ashi points） are also recorded. All measurements will be recorded at baseline （before the treatment）, at the end of each week during treatment and at t

Transportation sy.tems primarily.depend on vehicular flow on roads. Developed coun-tries have shifted towards automated signal control, which manages and updates signal sy.chronisation automatically. In contrast, traffic in underdeveloped countries is mainly.governed by.manual traffic light sy.tems. These existing manual sy.tems lead to numerous issues, wasting substantial resources such as time, energy. and fuel, as they.cannot make real‐time decisions. In this work, we propose an algorithm to determine traffic signal durations based on real‐time vehicle density. obtained from live closed circuit television camera feeds adjacent to traffic signals. The algorithm automates the traffic light sy.tem, making decisions based on vehicle density.and employ.ng faster R‐CNN for vehicle detection. Additionally. we have created a local dataset from live streams of Punjab Safe City.cameras in collaboration with the local police authority. The proposed algorithm achieves a class accuracy.of 96.6% and a vehicle detection accuracy.of 95.7%. Across both day.and night modes, our proposed method maintains an average precision, recall, f1 score, and vehicle detection accuracy.of 0.94, 0.98, 0.96 and 0.95, respectively. Our proposed work surpasses all evaluation metrics compared to state‐of‐the‐art methodologies.
