Non recurrent laryngeal nerve with right aberrant subclavian artery in recurrent case of papillary carcinoma of thyroid: an interesting clinical entity.

Background/objectives: A nonrecurrent laryngeal nerve is a rare anatomical variant and a routine preoperative imaging studies are not indicated. NRLN is related with absence of the brachiocephalic trunk and aberrant (mainly retroesophageal) course of theright subclavian artery which is evident on contrast enhanced CT scan of the chest.Case report: The patient presented with a swelling in the neck for 4 months which is slowly increasing in size. Patient gives history of a surgery done in the neck with an old midlinesuprasternal scar which was done 40 years earlier.laryngoscopic mirror examinartion was normal with moving vocal cords. Rest of the oral and oropharyngeal examination along with completeblood picture and biochemical investigations were normal. The patient was not a known diabetic or hypertensive.Conclusion: Accurate knowledge of frequent variations of the nerve along with the non recurrent variant reduces the risk of intraoperative injury. A nonrecurrent laryngealnerve(NRLN) is a rare anatomical variant and a routine preoperative imaging studies are not indicated. NRLN is related with absence of the brachiocephalic trunk and aberrant(mainly retroesophageal) course of the right subclavian artery which is evident on contrast enhanced CT scan of the chest.

Identification of Nonlinear Systems From the Knowledge Around Different Operating Conditions: A Feed-Forward Multi-Layer ANN Based Approach

The paper investigates nonlinear system identification using system output data at various linearized operating points. A feed-forward multi-layer Artificial Neural Network (ANN) based approach is used for this purpose and tested for two target applications i.e. nuclear reactor power level monitoring and an AC servo position control system. Various configurations of ANN using different activation functions, number of hidden layers and neurons in each layer are trained and tested to find out the best configuration. The training is carried out multiple times to check for consistency and the mean and standard deviation of the root mean square errors (RMSE) are reported for each configuration.Comment: "6 pages, 9 figures; The Second IEEE International Conference on Parallel, Distributed and Grid Computing (PDGC-2012), December 2012, Solan

EVALUATION OF FROZEN SEMEN BY A CROSOMAL INTEGRITY AND SPERM CONCENTRATION - TWO VITAL QUALITY PARAMETERS OF MALE FERTILITY IN BOVINES

Acrosomal integrity and sperm concentration are two important parameters to assess the quality of frozen semen doses which in terms validates the fertilizing capacity and conception rate. The present study was undertaken to evaluate acrosomal integrity by Giemsa’s stain and sperm concentration of FSS using improved neubauer chamber in Exotic pure Jersey, Crossbred Jersey, Indigenous Gir cattle and Indigenous Murrah buffalo prior to the field use. The overall values of Giemsa’s stain were observed as 73.74±0.31, 18.65±0.33 and 7.79±0.25 percent for Intact Acrosome, Partially Damaged Acrosome and Fully Damaged Acrosome, respectively. Overall values of sperm concentration were 21.98±0.28 million per straw. The study indicated that there was no significant difference (P<0.05) among the breeds and the values mostly correlates with the guideline of Minimum Standard Protocol for Production of bovine semen, 2012 of Govt. of India

Combined surgical and prosthetic approach for rehabilitation of frontonasal defect using custom made titanium implant: a case report

Cranial vault deformities as a sequelae to trauma may be as high as 70%. The basic indications for cranioplasty are improvement of disfigured aesthetics and to provide protection to the intra-cranial contents. The possibility of producing custom-made implants opened a new era in the reconstructive surgery of the craniofacial deformities. The outcome of craniofacial bone reconstruction is thought to be dependent on surgical skills, quality of adjacent soft tissues, size and location of the bone defect and choice of repair method. The use of autologous bone for craniofacial reconstruction may be restricted due to limited amounts of donor bone. Combined surgical and prosthetic rehabilitation of these structures utilizing craniofacial implants is a viable option which offers several advantages when compared to surgical reconstructive techniques alone. Predictability and superior aesthetics are the major advantages of this technique. In addition to the advantages of good biocompatibility and mechanical strength, titanium also provides the advantage of being light in weight. This clinical report highlights the combined surgical and prosthetic approach for the successful management of frontonasal defect

Improved Hybrid Model of HMM/GMM for Speech Recognition

In this paper, we propose a speech recognition engine using hybrid model of Hidden Markov Model (HMM) and Gaussian Mixture Model (GMM). Both the models have been trained independently and the respective likelihood values have been considered jointly and input to a decision logic which provides net likelihood as the output. This hybrid model has been compared with the HMM model. Training and testing has been done by using a database of 20 Hindi words spoken by 80 different speakers. Recognition rates achieved by normal HMM are 83.5% and it gets increased to 85% by using the hybrid approach of HMM and GMM
