Demonstration of long-reach PON using 10 Gb/s 3R burst-mode wavelength converter [PDF]
, 2013 Long-reach optical access networks promise significant cost savings. To merge existing metro and access networks to a single long-reach network, the long-reach technology has to address not only the power loss and fiber dispersion problems but also ...

Security proof of practical quantum key distribution with detection-efficiency mismatch
Physical Review Research, 2021 Quantum key distribution (QKD) protocols with threshold detectors are driving high-performance QKD demonstrations. The corresponding security proofs usually assume that all physical detectors have the same detection efficiency.

The eleven antenna: a compact low-profile decade bandwidth dual polarized feed for reflector antennas [PDF]
, 2006 A novel dual polarized ultrawide-band (UWB) feed with a decade bandwidth is presented for use in both single and dual reflector antennas. The feed has nearly constant beam width and 11 dBi directivity over at least a decade bandwidth.

Photovoltaic mismatch losses caused by moving clouds
Solar Energy, 2017 Abstract Mismatch losses is a major issue in the photovoltaic (PV) system and are mainly caused by partial shading; largest mismatch losses are caused by sharp shadows. These shadows are a typical problem for rooftop and residential installations.

Effects of Gain-Loss Frames in Negotiation: Loss Aversion, Mismatching, and Frame Adoption [PDF]
Organizational Behavior and Human Decision Processes, 1994 Examined negotiator cognition and behavior as a function of own frame, foreknowledge about opponent's frame, opponent's communicated frame, and their interactions. Prenegotiation information about the opponent's gain or loss frame on negotiator cognition and behavior was also examined. Ss were 107 undergraduates.

Calculation of Site Attenuation for Calculable Dipole Antennas [PDF]
Journal of Electromagnetic Engineering and Science, 2020 This paper presents a method for calculating the site attenuation (SA) of an open-area test site (OATS) for a pair of calculable dipole antennas with a 3-dB hybrid balun in the frequency range of 30 MHz to 1 GHz.

Stabilization of solitons in PT models with supersymmetry by periodic management
, 2011 We introduce a system based on dual-core nonlinear waveguides with the balanced gain and loss acting separately in the cores. The system features a "supersymmetry" when the gain and loss are equal to the inter-core coupling.

Endonuclease activities of MutLα and its homologs in DNA mismatch repair. [PDF]
, 2016 MutLα is a key component of the DNA mismatch repair system in eukaryotes. The DNA mismatch repair system has several genetic stabilization functions. Of these functions, DNA mismatch repair is the major one.

Addressing the Loss-Metric Mismatch with Adaptive Loss Alignment
, 2019 In most machine learning training paradigms a fixed, often handcrafted, loss function is assumed to be a good proxy for an underlying evaluation metric. In this work we assess this assumption by meta-learning an adaptive loss function to directly optimize the evaluation metric.
