Multicointegration is traditionally defined as a particular long run relationship among variables in parametric vector autoregressive model that introduces additional cointegrating links between these and partial sums of the equilibrium errors. This paper departs from model, using semiparametric formulation reveals explicit role singularity conditional covariance matrix plays determining multic...

This study presents a novel technique to enhance telephone speech signals. This technique is based on the Amplitude and Frequency Modulation (AM-FM) model, which represents the speech signal as the sum of N successive AM-FM signals. Based on a leastmean-square error criterion, each AM-FM signal is modified using an iterative algorithm in order to compensate for the deformation of the signal cau...

INTRODUCTION Ankylosing spondylitis (AS) is a chronic inflammatory disease that affects the axial skeletal system, causing pain and functional incapacity. To measure the impact of AS on patient's life, questionnaires are used to assess disease activity (BASDAI); functional incapacity (BASFI); and quality of life (ASQoL). Fibromyalgia (FM) is one of the most common causes of generalized pain and...

The advancement in fintech technological development emerging countries has accelerated the role of digital finance economic development. Digital assists financial inclusion; however, it may also increase chances instability due to systematic risks. Emerging are clutches shadow growth, which reduces taxable income revenue and creates pressure on inclusion prospects. current study attempts measu...

Previous studies in anesthetized animals reported that the primary auditory cortex (A1) showed homogenous phasic responses to FM tones, namely a transient response to a particular instantaneous frequency when FM sweeps traversed a neuron's tone-evoked receptive field (TRF). Here, in awake cats, we report that A1 cells exhibit heterogeneous FM responses, consisting of three patterns. The first i...

Uncemented revision cups are widely used in revision hip arthroplasty; they have shown good results. We report the the short term outcome with the cementless Pinnacle revision cup. All acetabular revisions using a Pinnacle revision cup between January 2007 and March 2010 were included. In March 2012, clinical scores were determined and the latest radiographs were assessed. Revision and radiogra...

Digital photogrammetry was performed on stereophotographs of the optic nerve head of a modified Zeiss model eye in which optic cups of varying depths could be simulated. Experiments were undertaken to determine the impact of both photographic and ocular variables on the photogrammetric measurements of cup depth. The photogrammetric procedure tolerates refocusing, repositioning, and realignment ...
