Marked drug-induced prolongation of the QT interval on the electrocardiogram is associated with Torsades de Pointes (TdP), a potentially life-threatening cardiac arrhythmia. Assessment of QT prolongation liability in the drug development process is required but is time and resource intensive. Current pre-clinical safety assessments use patch clamp analysis of the Human Ether-a-Go-Go (hERG) channel,...
We explore using a switchable detector array to reduce the deadtime effect in an OAM-encoded quantum system. For a 4-OAM-state system, the switchable 16-detector array could provide >15X incident photon rate improvement, as compared to a non-switchable 4-detector array.
We experimentally demonstrate an OAM-based quantum communication link populated by a classical channel. OAM enables an up to 100-Mbit/s quantum data rate as well as an additional 18.5-dB separation between the quantum and classical channels.
We demonstrate the use of orbital angular momentum based spatial spectrum analysis for the estimation of object parameters. The proposed approach is insensitive to object rotation or probing beam diffraction caused by object truncation.
In the process of multi axis machine tool, sometimes it is necessary to switch between the rotating spindle and the rotary feed shaft. In order to satisfy the request mentioned above, this article makes a brief introduction to the upper software and analyzes the control principle of spindle by using PMAC, combined with that, a method to deliver the automatic switching function between spindle mode...
Harmonic resonance problems can be aroused in the industrial power system in the presence of both nonlinear loads and shunt capacitors. This paper investigates the harmonic resonance problem by case-studying of a copper smelting plant low voltage power distribution system. A flexible selective harmonic compensation and resonance damping algorithm for shunt active power filter (SAPF) is proposed to...
The aim of this paper is to analyze the inter-relationship among the elements of water transportation system and to quantify the impact of each factor in safety and mobility. Firstly, the brittle source and brittle formation mechanism of water transportation system are identified and analyzed. Then, using the complex system brittleness theory to analyze the brittleness relationship between subsystems...
In computing systems, a job/process/task/thread may suspend itself when it has to wait for some other internal or external activities, such as computation offloading or memory accesses, to finish before it can continue its execution. In the literature, there are two commonly adopted self-suspending sporadic task models in real-time systems: 1) the dynamic self-suspension model and 2) the segmented...
Under Keel Clearance (UKC) is a key factor that affects loading rate and draft of Very Large Crude Carrier (VLCC). In order to prevent groundings caused by loading rate and draft increasing, it is necessary to study on UKC calculation model for VLCC. Based on analysis of UKC impact factors, this paper uses multiple linear regression to build UKC calculation model of the vessel in Bohai Sea by numerical...
1This paper answers several open questions of practical concerns to schedule soft real-time (SRT) tasks, to guarantee their bounded tardiness, under fixed-priority scheduling in homogeneous multiprocessor systems. We consider both cases with only SRT tasks and with mixed sets of SRT and hard real-time (HRT) tasks. For the case in which the system has only SRT tasks, we show that any fixed priority...
We present ATHOME, an Automatic Tunable wireless charging framework for smart low-power devices in current and future HOME. ATHOME automatically tunes the charging power of multiple stationary wireless chargers to provide enough energy that can continuously power up smart devices with varying working power profiles, while minimizing the total charging power to reduce energy cost. To reach this goal,...
We experimentally demonstrate beam displacement tracking and correction using orbital-angular-momentum (OAM) beams based position detection over a 400-Gbit/s OAM-multiplexed link. Power penalties <3 dB are achieved with the displacement up to ±10 mm.
Social networks allow rapid spread of ideas and innovations while the negative information can also propagate widely. When the cascades with different opinions reaching the same user, the cascade arriving first is the most likely to be taken by the user. Therefore, once misinformation or rumor is detected, a natural containment method is to introduce a positive cascade competing against the rumor...
The exhaustion of IPv4 addresses has led to the transition to IPv6 becoming a major task for the Internet. Providing IPv6 users with accessibility to IPv4 services has been one of the most challenging tasks during the IPv4/IPv6 transition. However, some protocols contain IP addresses in the application layer, resulting in incompatibilities in traversing the network-layer translators. In this paper,...
As a high-precision multi-axis motion controller designed by Delta Tau, PMAC has been widely used in industrial fields. Mirror image is a function through which can machine the same trace in other place of the workpiece, not only saving the tool setting time but also simplifying the edit of program. By this way, product could have good accuracy and interchangeability. However, researches aimed at...
Heterogeneous systems that contain multiple types of resources, such as CPUs and GPUs, are becoming increasingly popular thanks to the potential of achieving high performance and energy efficiency. In such systems, the problem of data mapping and communication for time-sensitive applications while reducing power and energy consumption is more challenging, since applications may have varied data management...
Given the need to achieve higher performance without driving up power consumption, energy usage and heat dissipation, most chip manufacturers have shifted to multicore architectures. An important subcategory of such architectures are those that are heterogeneous in design. By providing heterogeneous processing elements with different performance and energy characteristics in the same system, heterogeneous...
We experimentally demonstrate the use of orbital angular momentum (OAM) superposition as basis for the generation of a directed energy beam. Different OAM superpositions are tested with a maximum achieved peak power gain of ∼2.5.
We demonstrate 4-Gbit/s underwater transmission of multiplexed four green OAM beams using directly-modulated 520-nm laser diode. The influence of various channel conditions, including scattering, water currents and temperature gradient (water turbulence) on system performance is investigated.
We report a transmission of 2 Gb/s signal over a two-channels, 1.2 meter OAM-multiplexed optical underwater link through water thermal inhomogeneity using 2×2 CMA equalization to mitigate crosstalk and system performance degradation.
