Where does perseus arm starts and ends?
Best insight from top research papers
The Perseus Arm of the Milky Way starts between Galactic longitudes 120° and 140° and Galactic latitudes -1° to +4°, encompassing young clusters and young stellar objects . It extends outward with a width of 7.8 ± 0.2 km s−1 around the kinematic arm center, with a thickness averaging about 63 pc and a molecular layer centroid at 8.7 pc . In the anticenter direction, the Perseus Arm has been detected at a distance of 1.6 ± 0.2 kpc from the Sun, showing a surface density amplitude of around 10-14% for intermediate young stars, indicating its location within the co-rotation radius of the Milky Way spiral pattern .

What is the galactic coordinate of the orion arm?5 answersThe Galactic coordinate of the Orion arm is characterized by a narrow ellipsoid elongated in the direction of L1 = 77.1° ± 2.9°, with a symmetry plane inclined at an angle of 5.6° ± 0.2° to the Galactic plane. The longitude of the ascending node of this symmetry plane is approximately \(l_\Omega = 70^\circ \pm 3^\circ\). Additionally, the pitch angle of the Local spiral arm is estimated to be i = 12.9° ± 2.9°. This orientation is further supported by the absence of a deviation from the direction to the Galactic pole in the third axis of the position ellipsoid of Galactic masers. The Orion arm is a significant feature in the Milky Way, hosting star-forming complexes and playing a crucial role in the structure and dynamics of our galaxy.
What is the galactic longitude and latitude range of the perseus arm?4 answersThe Perseus Arm in the Milky Way spans a specific range in galactic coordinates. It is located in a segment with a galactic longitude of approximately 30 to 50 degrees, neighboring a lack of similar sources between longitudes of about 50 to 90 degrees. Additionally, a study focusing on a section of the Perseus Arm between Galactic longitudes 120 to 140 degrees and Galactic latitudes -1 to +4 degrees has been conducted, analyzing young structures within this region. Furthermore, research has been done to map the Perseus spiral arm in the outer Milky Way, determining its width, thickness, and gas mass surface density distribution along its length.
Where does the pectoralis major muscle start and stop?5 answersThe pectoralis major muscle originates from the anterior surface of the medial half of the clavicle, the anterior surface of the sternum, the first 7 costal cartilages, the sternal end of the sixth rib, and the aponeurosis of the external oblique of the anterior abdominal wall. It inserts at the lateral lip of the intertubercular sulcus of the humerus. The muscle has a broad origin from the clavicle, sternum, and the fifth through seventh costal cartilages, with muscle fibers fanning into three laminae before uniting into a single tendon that inserts into the bicipital groove of the humerus. The pectoralis major muscle is situated at the upper and fore part of the chest, anterior to the axilla.
What is the moment arm for the biceps brachii muscle?5 answersThe moment arm for the biceps brachii muscle varies depending on factors such as arm position and joint angles. In one study, the moment arm of the biceps brachii muscle was found to be the longest at 70 degrees of elbow flexion, while the moment arm at 25 and 120 degrees was nearly the same. Another study investigated the ratio of the biceps brachii moment arm at the shoulder to that at the elbow and found a range of values, with a mean value of 0.75. Additionally, a study examined the individual function of the arm muscles at the glenohumeral joint and determined the moment arms of the long and short heads of the biceps brachii muscle, among others. Overall, the moment arm for the biceps brachii muscle can vary depending on factors such as joint position and individual differences.
What is the role of arm swing in balance control during walking?5 answersArm swing plays a crucial role in balance control during walking. It has been found that arm swing affects dynamic balance in healthy young adults. In people with Parkinson's disease, absent arm swing leads to reduced step length and increased step time variability in the most affected leg. Additionally, absent arm swing reduces trunk movement and stability, particularly on the least affected side. On the other hand, dual tasking while walking increases step width variability and mediolateral trunk movement, suggesting that modifying foot placement is important for maintaining stability in dual task situations. Furthermore, arm swing has been shown to have an adaptive compensatory role in postural control, with mechanisms involving moving the center of pressure and rotating the trunk and upper limbs. Overall, arm swing contributes to maintaining balance and stability during walking, and its absence or alteration can have significant effects on gait patterns and stability.
What are drawbacks of ARM method?3 answersThe drawbacks of the ARM method include the need for arbitrage-free option prices, the identification of the closest arbitrage-free approximation in the presence of noise, and the potential for inconsistencies in quoted option prices for longer durations. Additionally, the ARM problem is computationally hard to solve, requiring critical design choices in the data analysis workflow. In the context of cache consistency, the implementation of the active refresh method (ARM) can pose challenges. Furthermore, when using arm images for biometric recognition, motion blur can degrade image quality and hinder vein information recovery.
