BACKGROUND Recessive mutant alleles of MYO7A, USH1C, CDH23, and PCDH15 cause non-syndromic deafness or type 1 Usher syndrome (USH1) characterised by deafness, vestibular areflexia, and vision loss due to retinitis pigmentosa. For CDH23, encoding cadherin 23, non-syndromic DFNB12 deafness is associated primarily with missense mutations hypothesised to have(More)
Control charts are widely used for process monitoring. They show whether the variation is due to common causes or whether some of the variation is due to special causes. To detect large shifts in the process, Shewhart-type control charts are preferred. Cumulative sum (CUSUM) and exponentially weightedmoving average (EWMA) control charts are generally used(More)
OBJECTIVE To identify the genetic cause of prelingual sensorineural hearing loss in Pakistani families using a next-generation sequencing (NGS)-based mutation screening test named OtoSeq. STUDY DESIGN Prospective study. SETTING Research laboratory. SUBJECTS AND METHODS We used 3 fluorescently labeled short tandem repeat (STR) markers for each of the(More)
The present paper is devoted to introduce a four-parameter modification of new flexible Weibull distribution. The proposed model will be called modified new flexible Weibull distribution, able to model lifetime phenomena with increasing or bathtub-shaped failure rates. Some of its mathematical properties will be studied. The approach of maximum likelihood(More)
This article considers a new function to propose a new lifetime model. The new model is introduced by utilizing the linear scheme of the two logarithms of cumulative hazard functions. The new model is named as new extended Weibull distribution, and is able to model data with unimodal or modified unimodal shaped failure rates. A brief explanation of the(More)
This paper proposes a new Active Queue Management (AQM) technique, called CHOKe-RH (CHOKe with Recent Drop History), to achieve congestion control in the network and to protect TCP responsive flows from unresponsive flows. CHOKe-RH retains the good features of RED and CHOKe, such as the low processing cost, while overcomes their limitations. CHOKe-RH(More)
