One-step deterministic polarization entanglement purification using spatial entanglement

open access: yes, 2010
We present a one-step deterministic entanglement purification protocol with linear optics and postselection. Compared with the Simon-Pan protocol (Phys. Rev. Lett. 89, 257901 (2002)), this one-step protocol has some advantages.

Rebound Effects in Circular Manufacturing: Overview of Potential Rebound Mechanisms Activated by Circular Strategies Across Key Business Processes

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Circular economy (CE) is increasingly adopted by the manufacturing industry to decouple economic growth from environmental impacts by optimizing resource use and minimizing waste generation. Nevertheless, circular manufacturing often triggers systemic responses that diminish or offset their potential environmental gains, resulting in the so ...

Application of Advanced Early Warning Systems with Adaptive Protection [PDF]

open access: yes, 2015
This project developed and field-tested two methods of Adaptive Protection systems utilizing synchrophasor data. One method detects conditions of system stress that can lead to unintended relay operation, and initiates a supervisory signal to modify ...

P and M class phasor measurement unit algorithms using adaptive cascaded filters [PDF]

open access: yes, 2013
The new standard C37.118.1 lays down strict performance limits for phasor measurement units (PMUs) under steady-state and dynamic conditions. Reference algorithms are also presented for the P (performance) and M (measurement) class PMUs.

Real‐time lithology identification while drilling based on drill cuttings image analysis with ensemble learning

open access: yesDeep Underground Science and Engineering, EarlyView.
A lithology identification while drilling method was developed, integrating an automated cuttings sampling system, a smart drilling rig, and an ensemble learning model. Underground trials achieved 97.42% accuracy in real‐time identification of cuttings lithology and composition, enhancing hazard management and supporting unmanned drilling technology in

Transient Charging Dynamics in Stacked Ga2O3/ZnO Photovoltaic Units Governing Wavelength‐Selective Polarity Switching

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reveals a “Photovoltaic‐Capacitance” coupling mechanism in stacked Ga2O3/ZnO devices, defining the ZnO/graphene interface as a novel Photovoltaic Dynamic‐Capacitor (PDC). The wavelength‐selective bipolar response enables a physical layer secure communication protocol based on ternary optical logic (“1,” “0,” “−1”).

Pushdown Compression [PDF]

open access: yes, 2007
The pressing need for eficient compression schemes for XML documents has recently been focused on stack computation [6, 9], and in particular calls for a formulation of information-lossless stack or pushdown compressors that allows a formal analysis of ...

Proteomic Profiling of Primary Hippocampal Neurons Reveals Noncanonical GFAP Expression and Metabolic Adaptations in Glia‐Free Culture

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Despite their widespread use as a research model, a comprehensive, quantitative proteomic profile of the cultured hippocampal neurons has remained unexplored. Here, we provide the first global proteomic characterization of primary murine hippocampal neurons cultured for 14 days under near‐physiological glucose conditions (2.5 mM).

Development of New Multiple Compound Cutting Bit

open access: yesShiyou jixie, 2016
In order to raise the ROP of bit in the abrasive hard formation and extend bit service life, a new multiple compound cutting bit is developed. The bit adopts the three-level cutting structure of PDC+cone-shaped PDC tooth+impregnated diamond segment, with
