BACKGROUND The aim of this study was to evaluate the clinical efficiency of transduodenal ampullectomy (TDA) compared to conventional pancreatoduodenectomy (PD) in patients with early ampullary cancers. METHODS We carried out a retrospective study by reviewing the medical records of 43 patients with early ampullary cancer who underwent either TDA or PD from January 2001 to December 2014. TDA ...

In recent years, persistent homology (PH) and topological data analysis (TDA) have gained increasing attention in the fields of shape recognition, image analysis, machine learning, computer vision, computational biology, brain functional networks, financial haze detection, etc. this article, we will focus on stock markets demonstrate how TDA can be useful regard. We first explain signatures tha...

Little is known about plasma drug concentrations relative to quantitative susceptibility in patients with multidrug-resistant tuberculosis (MDR-TB). We previously described a TB drug activity (TDA) assay that determines the ratio of the time to detection of plasma-cocultured Mycobacterium tuberculosis versus control growth in a Bactec MGIT system. Here, we assess the activity of individual drug...

This study investigates the combined efficacy of waste-tire-derived aggregate (TDA) materials and hydrated lime on compactability, compressive strength swelling potential a highly expansive soil from South Australia. A total 21 mix-designs, covering comprehensive range soil–TDA–lime combinations, were examined through standard Proctor compaction, unconfined (UCS) oedometer swell tests. The mobi...

Hand movement classification based on Electromyo-graphy (EMG) signals has been extensively investigated in the past decades as a promising approach used for controlling upper prosthetics or robotics. Topological data analysis is relatively new and increasingly popular tool science that uses mathematical techniques from topology to analyze understand complex sets. This paper proposes method clas...

The enormous volume of literature has widely discussed the aid–growth correlation while identification their causal relationship remains elusive and mixed. main objective this article is to investigate whether aid sources matter for explaining nexus among African low-income countries (LICs) during 2000–2017. A novel feature study that it takes into account three proxies (i.e. total [TA], tradit...

This paper describes various time-domain methods useful for analyzing the experimental data obtained from a circular cylinder force in terms of both wave and current for estimation of the drag and inertia coefficients applicable to the Morison’s equation. An additional approach, weighted least squares method is also introduced. A set of data obtained from experiments on heavily roughened circul...

The synthesis and subsequent photophysical investigation of [Pt(mesBIAN)(tda)], where mesBIAN is bis(mesitylimino)acenaphthene and tda is tolan-2,2'-diacetylide, reveal excited-state characteristics best described as triplet charge transfer ((3)CT) in nature upon visible light excitation. Large ground-state dipole moments are apparent as the absorption spectrum dramatically red-shifts with decr...

A novel two-dimensional coordination polymer Zn(tda)H2O [tda = S(CH(2)COO)2(2-)] was synthesized under hydrothermal conditions. The compound crystallized in monoclinic space group P2(1) with a = 16.4154(17) A, b = 5.2133(6) A, c = 16.4210(17) A, beta = 114.165(2) degrees , V = 1282.1(2) A3, and Z = 8. The structure features two-dimensional, noncentrosymmetric networks with a pseudohexagonal net...

We develop a method for analyzing multivariate time series using topological data analysis (TDA) methods. The proposed methodology involves converting the to point cloud data, calculating Wasserstein distances between persistence diagrams and k-nearest neighbours algorithm (k-NN) supervised machine learning. Two methods (symmetry-breaking anchor points) are also introduced enable TDA better ana...
