SAQ: semi-algebraic quartet reconstruction.

IEEE/ACM Trans Comput Biol Bioinform 2021 Aug 2;PP. Epub 2021 Aug 2.

We present the phylogenetic quartet reconstruction method SAQ (Semi-Algebraic Quartet reconstruction). SAQ is consistent with the most general Markov model of nucleotide substitution and, in particular, it allows for rate heterogeneity across lineages. Based on the algebraic and semi-algebraic description of distributions that arise from the general Markov model on a quartet, the method outputs normalized weights for the three trivalent quartets (which can be used as input of quartet-based methods).

Desmoplakin cardiomyopathy and arrhythmogenic right ventricular cardiomyopathy: two distinct forms of cardiomyopathy?

Minerva Cardiol Angiol 2021 Aug 2. Epub 2021 Aug 2.

Molecular Cardiology, Istituti Clinici Scientifici Maugeri, IRCCS, Pavia, Italy -

The confirmation of a hypothesis that desmoplakin-related (DSP) cardiomyopathy could represent a distinct clinical entity from the classical, RV-dominant, form of arrhythmogenic cardiomyopathy (ACM), most frequently caused by PKP2 mutations, would without any shadow of doubt signify a turning point in the history of this disease. The concept of gene-specific diseases underneath the umbrella diagnosis of ACM would bring fundamental changes not only in the clinical, diagnostic and therapeutic approach, but also in terms of risk stratification, pushing the scientific community towards a more patient-centred view of the disease, similarly to what has already been done in other inherited arrhythmogenic disease (e.g. Read More

A Survey of Unsupervised Deep Domain Adaptation.

ACM Trans Intell Syst Technol 2020 Sep 5;11(5):1-46. Epub 2020 Jul 5.

Washington State University, USA.

Deep learning has produced state-of-the-art results for a variety of tasks. While such approaches for supervised learning have performed well, they assume that training and testing data are drawn from the same distribution, which may not always be the case. As a complement to this challenge, single-source unsupervised domain adaptation can handle situations where a network is trained on labeled data from a source domain and unlabeled data from a related but different target domain with the goal of performing well at test-time on the target domain.

Identification of functional microbial modules through network-based analysis of meta-microbial features using matrix factorization.

IEEE/ACM Trans Comput Biol Bioinform 2021 Jul 30;PP. Epub 2021 Jul 30.

As the microbiome is composed of a variety of microbial interactions, it is imperative in microbiome research to identify a microbial sub-community that collectively conducts a specific function. However, current methodologies have been highly limited to analyzing conditional abundance changes of individual microorganisms without considering group-wise collective microbial features. To overcome this limitation, we developed a network-based method using nonnegative matrix factorization (NMF) to identify functional meta-microbial features (MMFs) that, as a group, better discriminate specific environmental conditions of samples using microbiome data.

Modeling Two Dimensional Touch Pointing.

Proc ACM Symp User Interface Softw Tech 2020 Oct 20;2020:858-868. Epub 2020 Oct 20.

Department of Computer Science, Stony Brook University, Stony Brook, NY, United States.

Modeling touch pointing is essential to touchscreen interface development and research, as pointing is one of the most basic and common touch actions users perform on touchscreen devices. Finger-Fitts Law [4] revised the conventional Fitts' law into a 1D (one-dimensional) pointing model for finger touch by explicitly accounting for the fat finger ambiguity (absolute error) problem which was unaccounted for in the original Fitts' law. We generalize Finger-Fitts law to 2D touch pointing by solving two critical problems. Read More

Towards Knowledge Maintenance in Scientific Digital Libraries with the Keystone Framework.

Proc ACM/IEEE Joint Conf Digit Libr 2020 Aug 1;2020:217-226. Epub 2020 Aug 1.

School of Information Sciences, University of Illinois at Urbana-Champaign, Champaign, IL USA.

Scientific digital libraries speed dissemination of scientific publications, but also the propagation of invalid or unreliable knowledge. Although many papers with known validity problems are highly cited, no auditing process is currently available to determine whether a citing paper's findings fundamentally depend on invalid or unreliable knowledge. To address this, we introduce a new framework, the keystone framework, designed to identify when and how citing unreliable findings impacts a paper, using argumentation theory and citation context analysis.
