In this paper, we define new subclasses ${S}^{*}_{q}(alpha,Phi),$ ${M}_{q}(alpha,Phi)$ and ${L}_{q}(alpha,Phi)$ of analytic functions in the space of logistic sigmoid functions based on quasi--subordination and determine the initial coefficient estimates $|a_2|$ and $|a_3|$ and also determine the relevant connection to the classical Fekete--Szeg"o inequalities. Further, we discuss the improved ...

actinomycosis is a rare and chronic infectious disease caused by a non-spore gram- positive, anaerobic bacterium that rarely infects the colon, in particular the left colon. a 53-year-old woman was referred to us due to chronic abdominal pain, bloating, a few episodes of bloody-mucous rectal discharge, and  change of bowel habits. her medical history and physical examination were unremarkable. ...

In this paper the accuracy of two machine learning algorithms including SVM and Bayesian Network are investigated as two important algorithms in diagnosis of Parkinson’s disease. We use Parkinson's disease data in the University of California, Irvine (UCI). In order to optimize the SVM algorithm, different kernel functions and C parameters have been used and our results show that SVM with C par...

BACKGROUND Multidisciplinary laparoscopic treatment is the standard of care for radical treatment of deep infiltrating pelvic endometriosis. If bowel resection is necessary, a muscle-split or Pfannenstiel incision is also required. The avoidance of any laparotomy could decrease surgical stress response, give a faster return to normal bowel function, decrease post-operative pain and reduce wound...

We investigated the performance of artificial neural network (ANN)-based nonlinear equalizers for optical nonlinearity compensation by comparing activation functions, including a sigmoid function, ReLU, and Leaky ReLU. compared learning speeds performances evaluating resulting error vector magnitudes compensated signals. The was using simulated 100-km fiber transmission 10-GSymbol/s 16QAM When ...

Dry matter accumulation data for juvenile Indian Olive saplings was modelled using linear and non- regression models. The gathered bimonthly two years i.e., twelve readings. Linear, Quadratic, Power, Sigmoid, Exponential models performed quite well cumulative growth (Adj. R2 > 0.93). Sigmoid model (Chapman- Richard) demonstrated upper asymptotic values ranged between 179.96- 334.49 grams all...

In the literature, little attention is paid to devising and analyzing novel one dimensional chaotic mappings. our previous efforts, we have tried fold, translation & scale on arctangent function sigmoid respectively, which brings good results. this paper, do same obtain a variant of Hyperbolic Cosine Function. Both Bifurcation Diagram Lyapunov Exponent Spectrum manifest that new mapping pos...

The logistic sigmoid function curve provides an accurate description of the baroreflex input-output relationship and is the most commonly used equation for this purpose. The threshold (Thr) and saturation (Sat) values for the baroreflex are commonly defined as the values of mean arterial pressure (MAP) at which the reflexly controlled variable (e.g., heart rate or sympathetic nerve activity) is...

Abstract Distributed power supply access to the system affects tidal distribution of network. The article establishes a mathematical optimization model with network loss minimization and load balance as objective function. In this paper, idea elite strategy is introduced into gravitational search algorithm combined Sigmoid function, an method reconfiguration based on improved proposed by improv...

BACKGROUND AND PURPOSE Bone wax is a hemostatic agent that has been reported in some instances to migrate into the sigmoid sinus following posterior fossa surgery. The purpose of this study was to characterize the CT and MR imaging findings of this entity. MATERIALS AND METHODS The study included 212 consecutive patients who underwent posterior fossa surgery and postoperative CT and contrast-...
