Quantum advantage for probabilistic one-time programs.

Nat Commun 2018 12 6;9(1):5225. Epub 2018 Dec 6.

Vienna Center for Quantum Science and Technology, Faculty of Physics, University of Vienna, Boltzmanngasse 5, 1090, Vienna, Austria.

One-time programs, computer programs which self-destruct after being run only once, are a powerful building block in cryptography and would allow for new forms of secure software distribution. However, ideal one-time programs have been proved to be unachievable using either classical or quantum resources. Here we relax the definition of one-time programs to allow some probability of error in the output and show that quantum mechanics offers security advantages over purely classical resources.

Advancements in technology and digitization have ushered in novel ways of enhancing tissue-based research via digital microscopy and image analysis. Whole slide imaging scanners enable digitization of histology slides to be stored in virtual slide repositories and to be viewed via computers instead of microscopes. Easier and faster sharing of histologic images for teaching and consultation, improved storage and preservation of quality of stained slides, and annotation of features of interest in the digital slides are just a few of the advantages of this technology.

The Analysis and Suppressing of Non-Uniformity in a High-Speed Spike-Based Image Sensor.

Sensors (Basel) 2018 Dec 2;18(12). Epub 2018 Dec 2.

School of Microelectronics, Tianjin University and Tianjin Key Laboratory of Imaging and Sensing Microelectronic Technology, No. 92 Weijin Road, Nankai District, Tianjin 300072, China.

In this paper, the non-ideal factors, which include spatial noise and temporal noise, are analyzed and suppressed in the high-speed spike-based image sensor, which combines the high-speed scanning sequential format with the method that uses the interspike time interval to indicate the scene information. In this imager, spatial noise contains device mismatch, which results in photo response non-uniformity (PRNU) and the non-uniformity of dark current. By multiplying the measured coefficient matrix the photo response non-uniformity is suppressed, and the non-uniformity of dark current is suppressed by correcting the interspike time interval based on the time interval of dark current.

Behav Res Methods 2018 Dec 3. Epub 2018 Dec 3.

Faculty of Psychology and Educational Sciences, imec-ITEC, KU Leuven, Leuven, Belgium.

Electronic learning systems have received increasing attention because they are easily accessible to many students and are capable of personalizing the learning environment in response to students' learning needs. To that end, using fast and flexible algorithms that keep track of the students' ability change in real time is desirable. Recently, the Elo rating system (ERS) has been applied and studied in both research and practical settings (Brinkhuis & Maris, 2009; Klinkenberg, Straatemeier, & van der Maas in Computers & Education, 57, 1813-1824, 2011).

Detection of herpesvirus capsids in transmission electron microscopy images using transfer learning.

Histochem Cell Biol 2018 Nov 28. Epub 2018 Nov 28.

Central Facility for Electron Microscopy, Ulm University, Ulm, Germany.

The detailed analysis of secondary envelopment of the Human betaherpesvirus 5/human cytomegalovirus (HCMV) from transmission electron microscopy (TEM) images is an important step towards understanding the mechanisms underlying the formation of infectious virions. As a step towards a software-based quantification of different stages of HCMV virion morphogenesis in TEM, we developed a transfer learning approach based on convolutional neural networks (CNNs) that automatically detects HCMV nucleocapsids in TEM images. In contrast to existing image analysis techniques that require time-consuming manual definition of structural features, our method automatically learns discriminative features from raw images without the need for extensive pre-processing.

Generalized Unitary Coupled Cluster Wavefunctions for Quantum Computation.

J Chem Theory Comput 2018 Nov 28. Epub 2018 Nov 28.

We introduce a unitary coupled-cluster (UCC) ansatz termed k-UpCCGSD that is based on a family of sparse generalized doubles operators which provides an affordable and systematically improvable unitary coupled-cluster wavefunction suitable for implementation on a near-term quantum computer. k-UpCCGSD employs k products of the exponential of pair coupled-cluster double excitation operators (pCCD), together with generalized single excitation operators. We compare its performance in both efficiency of implementation and accuracy with that of the generalized UCC ansatz employing the full generalized single and double excitation operators (UCCGSD), as well as with the standard ansatz employing only single and double excitations (UCCCSD).

A Parallel Architecture for the Partitioning Around Medoids (PAM) Algorithm for Scalable Multi-Core Processor Implementation with Applications in Healthcare.

Sensors (Basel) 2018 Nov 25;18(12). Epub 2018 Nov 25.

Department of Computer & Software Engineering, CE&ME, National University of Sciences & Technology, Islamabad 44000, Pakistan.

Clustering is the most common method for organizing unlabeled data into its natural groups (called clusters), based on similarity (in some sense or another) among data objects. The Partitioning Around Medoids (PAM) algorithm belongs to the partitioning-based methods of clustering widely used for objects categorization, image analysis, bioinformatics and data compression, but due to its high time complexity, the PAM algorithm cannot be used with large datasets or in any embedded or real-time application. In this work, we propose a simple and scalable parallel architecture for the PAM algorithm to reduce its running time. Read More

Department of Bioengineering, McGill University, Montreal, Quebec, Canada H3A 0E9.

On-chip network-based computation, using biological agents, is a new hardware-embedded approach which attempts to find solutions to combinatorial problems, in principle, in a shorter time than the fast, but sequential electronic computers. This analytical review starts by describing the underlying mathematical principles, presents several types of combinatorial (including NP-complete) problems and shows current implementations of proof of principle developments. Taking the subset sum problem as example for in-depth analysis, the review presents various options of computing agents, and compares several possible operation 'run modes' of network-based computer systems.

Nucleic Acid Strand Displacement with Synthetic mRNA Inputs in Living Mammalian Cells.

ACS Synth Biol 2018 Nov 20. Epub 2018 Nov 20.

Department of Electrical Engineering , University of Washington , Seattle , Washington 98195 , United States.

Strand displacement reactions are widely used in DNA nanotechnology as a building block for engineering molecular computers and machines. Here, we demonstrate that strand displacement-based probes can be triggered by RNA expressed in mammalian cells, thus taking a step toward adapting the DNA nanotechnology toolbox to a cellular environment. We systematically compare different probe architectures in order to identify a design that works robustly in living cells. Read More

Long-term use of a neural prosthesis in progressive paralysis.

Sci Rep 2018 Nov 14;8(1):16787. Epub 2018 Nov 14.

Systems Neuroscience Section, Department of Rehabilitation for Brain Functions, Research Institute of National Rehabilitation for Persons with Disabilities, Saitama, Japan.

Brain-computer interfaces (BCIs) enable communication with others and allow machines or computers to be controlled in the absence of motor activity. Clinical studies evaluating neural prostheses in amyotrophic lateral sclerosis (ALS) patients have been performed; however, to date, no study has reported that ALS patients who progressed from locked-in syndrome (LIS), which has very limited voluntary movement, to a completely locked-in state (CLIS), characterized by complete loss of voluntary movements, were able to continue controlling neural prostheses. To clarify this, we used a BCI system to evaluate three late-stage ALS patients over 27 months. Read More

Iss2Image: A Novel Signal-Encoding Technique for CNN-Based Human Activity Recognition.

Sensors (Basel) 2018 Nov 13;18(11). Epub 2018 Nov 13.

Department of Computer Science and Engineering, Kyung Hee University, (Global Campus), 1732, Deogyeong-daero, Giheung-gu, Yongin-si, Gyeonggi-do 17104, Korea.

The most significant barrier to success in human activity recognition is extracting and selecting the right features. In traditional methods, the features are chosen by humans, which requires the user to have expert knowledge or to do a large amount of empirical study. Newly developed deep learning technology can automatically extract and select features. Read More

User-centered, interaction design research approaches to inform the development of health risk behavior intervention technologies.

Internet Interv 2019 Mar 2;15:1-9. Epub 2018 Nov 2.

Center for Alcohol and Addictions Studies, Brown University School of Public Health, Providence, RI 02906, United States of America.

Background: Computers have tremendous potential for helping people change behaviors that put their health at risk. This potential has led to the development of a variety of health behavior intervention technologies (BITs) in recent years. While many of these BITs have been informed by scientific theories on behavior change, poor design can fail to engage intended users. Read More
