Quantum nonlocality with arbitrary limited detection efficiency [PDF]

open access: yes, 2015
The demonstration and use of nonlocality, as defined by Bell's theorem, rely strongly on dealing with non-detection events due to losses and detector inefficiencies. Otherwise, the so-called detection loophole could be exploited. The only way to avoid this is to have detection efficiencies that are above a certain threshold.

Evaluating the origin and spread of spotted lanternfly (Lycorma delicatula) in Japan

open access: yesPopulation Ecology, Volume 67, Issue 2, Page 162-179, April 2025.
The invasive spotted lanternfly (Lycorma delicatula) is native to China and is a serious economic pest in the Republic of Korea and the United States, though it is not considered a pest in Japan. We established a distribution map of L. delicatula in Japan through a comprehensive review of published literature and citizen science reports and analyzed ...

Development of a highly sensitive colloidal gold semiquantitative method for the determination of difenoconazole residues in citrus

open access: yesFrontiers in Nutrition
IntroductionDifenoconazole (DIFE) is a common pesticide used in citrus cultivation; excessive intake can cause neurological damage to the organism, and the existing colloidal gold immunochromatographic test strips cannot meet the requirements for the ...

Trustworthy Anomaly Detection: A Survey [PDF]

open access: yesarXiv, 2022
Anomaly detection has a wide range of real-world applications, such as bank fraud detection and cyber intrusion detection. In the past decade, a variety of anomaly detection models have been developed, which lead to big progress towards accurately detecting various anomalies.

On the Capacity of Waveform Channels Under Square-Law Detection of Time-Limited Signals [PDF]

open access: yes, 2020
Capacity bounds for waveform channels under square-law detection of time-limited complex-valued signals are derived. The upper bound is the capacity of the channel under (complex-valued) coherent detection. The lower bound is one bit less, per dimension, than the upper bound.

Optimum Small Optical Beam Displacement Measurement

open access: yes, 2004
We derive the quantum noise limit for the optical beam displacement of a TEM00 mode. Using a multimodal analysis, we show that the conventional split detection scheme for measuring beam displacement is non-optimal with 80% efficiency.

Comparison of kinship‐identification methods for robust stock assessment using close‐kin mark–recapture data for Pacific bluefin tuna

open access: yesPopulation Ecology, Volume 67, Issue 2, Page 140-152, April 2025.
In this study, we compared three methods for kinship identification using different algorithms in samples of wild Pacific bluefin tuna and generated genotyping data. The three methods resulted in different numbers of inferred kinship pairs for both generated and actual data. Particularly for the half‐sibling pairs, considerable number of false‐positive

Representation Learning in Anomaly Detection: Successes, Limits and a Grand Challenge [PDF]

open access: yesarXiv, 2023
In this perspective paper, we argue that the dominant paradigm in anomaly detection cannot scale indefinitely and will eventually hit fundamental limits. This is due to the a no free lunch principle for anomaly detection. These limitations can be overcome when there are strong tasks priors, as is the case for many industrial tasks.

Numerical Optical Centroid Measurements

open access: yes, 2013
Optical imaging methods are typically restricted to a resolution of order of the probing light wavelength $\lambda_p$ by the Rayleigh diffraction limit. This limit can be circumvented by making use of multiphoton detection of correlated $N$-photon states,

Tunable sensor response by voltage-control in biomimetic hair flow sensors [PDF]

open access: yes, 2013
We present an overview of improvements in detection limit and responsivity of our biomimetic hair flow sensors by electrostatic spring-softening (ESS). Applying a DC-bias voltage to our capacitive flow sensors improves the responsively by up to 80% for ...
