A cDNA clone encoding a 253 amino acid tropomyosin was isolated from Hydra in a differential screen for head-specific genes. The Hydra tropomyosin gene, designated trop1, is a single copy gene, lacks introns and is strongly expressed in tentacle-specific epithelial cells. Analysis of protein synthesis in head and gastric tissue indicated a high rate of tropomyosin synthesis in head tissue. Immu...

Isolated, full-thickness articular cartilage lesions of the glenohumeral joint can cause pain, mechanical symptoms, and impaired function. Reports on operative management of these injuries with arthroscopic techniques, such as marrow stimulation, have shown improvement in patient symptoms. In cases where the subchondral bone is involved, osteochondral allograft (OCA) transplantation has shown p...

introduction: nasopharyngeal carcinoma is one of the most common malignancies in the head and neck region and radiotherapy is its treatment of choice. in spite of the fact that it is widely used, due to the presence of many sensitive organs or tissues in this region, patients may suffer from a wide range of side effects. one such sensitive tissue is the spinal cord. if the absorbed dose to spin...

there are many techniques for reconstruction after total pharyngolaryngoesophagectomy. the use of a transposed stomach to restore gastrointestinal continuity, and this combined cervical and abdominal approach for pharyngolaryngoesophagectomy and gastric pull up has become one of the most popular. this retrospective study is a review of 50 consecutive iranian patients who underwent pharyngolaryn...

Target detection in synthetic aperture radar (SAR) images has a wide range of applications military and civilian fields. However, for engineering involving edge deployment, it is difficult to find suitable balance accuracy speed anchor-based SAR image target algorithms. Thus, an anchor-free algorithm ship targets with deep saliency representation, called SRDet, proposed this paper improve perfo...

â â â â â  abstract: â  as the number of independent countries increases and their economies become more integrated, we would expect to observe more multi-country currency ::::union::::s. this paper explores the pros and cons for different countries to adopt as an anchor the us dollar, the euro or the yen. in addition, it addresses the question of how co-movement of outputs and prices would res...

An artificial phospholipid, possessing saturated alkyl chains as a membrane anchor and protein recognition site as well as an Fe(III)-EDTA moiety as a protein cleavable polar head group, was designed and synthesized based on the amidite method for the purpose of examination of cleavage of integral membrane proteins.

Object detection has been vigorously investigated for years but fast accurate real-world scenes remains a very challenging problem. Overcoming drawbacks of single-stage detectors, we take aim at precisely detecting objects static and temporal in real time. Firstly, as dual refinement mechanism, novel anchor-offset is designed, which includes an anchor refinement, feature location deformable hea...

Deep learning object detection methods are usually based on anchor-free or anchor-based scheme for extracting proposals and one-stage two-stage structure producing final predictions. As each has its own strength weakness, combining their in a unified framework is an interesting research topic. However, this topic not attracted much attention recent years. This paper presents method that utilize...

Cameras for traffic surveillance are usually pole-mounted and produce images that reflect a birds-eye view. Vehicles in such images, general, assume an ellipse form. A bounding box the vehicles includes large empty space when vehicle orientation is not parallel to edges of box. To circumvent this problem, present study applied ellipses non-anchor-based, single-shot detection model (CenterNet). ...
