The supracoracoideus (SUPRA) is the primary upstroke muscle for avian flight and is the antagonist to the downstroke muscle, the pectoralis (PECT). We studied in vivo contractile properties and mechanical power output of both muscles during take-off, level and landing flight. We measured muscle length change and activation using sonomicrometry and electromyography, and muscle force development ...

BACKGROUND Among the vascular involvements of Takayasu arteritis, a supra-valvular aortic stenosis has been reported very rarely. We report a case of surgically corrected, supra-valvular aortic stenosis caused by Takayasu arteritis. CASE PRESENTATION A 32-year-old female was diagnosed with supra-valvular aortic stenosis by transthoracic echocardiography for the evaluation of cardiac murmur wi...

In this paper, a supra-threshold spatio-velocity CSF experiment is described. It consists in a contrast matching task with a methods of limits procedure. Results enable the determination of contrast perception functions which give, for given spatial and temporal frequencies, the perceived contrast of a moving stimulus. These contrast perception functions are then used to construct supra-thresho...

This paper presents a novel topology of single-phase multilevel inverter for low and high power applications. It consists of polarity (Level) generation circuit and H Bridge. The proposed topology can produce higher output voltage levels by connecting dc voltage sources   in series and parallel. The proposed topology utilizes minimum number of power electronic devices which helps in reduction o...

Prosodic research in recent years has been supported by a number of automatic analysis tools aimed at simplifying the work that is requested to study intonation. The need to analyze large amounts of data and to inspect phenomena that are often ambiguous and difficult to model makes the prosodic research area an ideal application field for computer based processing. One of the main challenges in...

Major depressive disorder is associated with abnormal anatomical and functional connectivity, yet alterations in whole cortical thickness topology remain unknown. Here, we examined cortical thickness in medication-free adult depression patients (n = 76) and matched healthy controls (n = 116). Inter-regional correlation was performed to construct brain networks. By applying graph theory analysis...

This paper discusses the evidence on electricity reform and relates it to the current situation of the South East Europe (SEE) electricity market. We begin by discussing the main elements of the European Union (EU) electricity reform model. Then we go on to discuss emerging good practice in the regulation of national electricity markets in the EU. This is important because it reflects the key r...

فرض کنیم a یک حلقه ی یکدار کاهش یافته (فاقد عنصر پوچ توان غیر بدیهی)باشد. خانواده تمام ایدآلهای اول سره از a را با spec(a)و خانواده تمام ایدآلهای اول مینیمال درa را باmin(a) نمایش می دهیم. مطالعات خوبی در مورد توپولوژی هسته غلافی (hull-kernel topology) یا همان توپولوژی زاریسکی،روی min(a)انجام شده است.به عنوان مثال این توپولوژی دارای پایه ای از زیرمجموعه های بستباز است. در این مقاله بر روی min...

In this paper, we introduce the concepts of right, left and product stabilizers on hoops and study some properties and the relation between them.  And we try to find that how they can be equal and investigate that under what condition they can be filter, implicative filter, fantastic and positive implicative filter. Also, we prove that  right and product stabilizers are filters and if they are ...
