In this article, we propose a novel and highly practical score-level fusion approach called dynamic belief (DBF) that directly integrates inference scores of individual detections from multiple object detection methods. To effectively integrate the outputs detectors, level ambiguity in each score is estimated using confidence model built on precision-recall relationship corresponding detector. ...
Crosslinkable hole transport materials (HTMs) with high triplet energies would have a balance of carrier injection into the emitting material layer, suppressing exciton quenching and resulting in high-performance solution-processed organic light-emitting diode (OLED) devices. Two novel crosslinkable HTMs different central units, N2, N8-di-p-tolyl-N2,N8-bis(4-vinylphenyl)dibenzo[b,d]thiophene-2,...
Chronic lymphocytic leukemia (CLL) clones contain subpopulations differing in time since the last cell division (“age”): recently born, proliferative (PF; CXCR4DimCD5Bright), intermediate (IF; CXCR4IntCD5Int), and resting (RF; CXCR4BrightCD5Dim) fractions. Herein, we used deuterium (2H) incorporation into newly synthesized DNA patients to refine kinetics of CLL by characterizing two additional ...
Drought can weaken forest activity and even lead to mortality, the response of different types drought be diverse. Deciduous broadleaf (DBF) deciduous needleleaf (DNF) are two majority in northern China. In this region, a severe event happened 2002. However, due lack data, spatio-temporal characteristics ecosystem stability here remain unclear. study, we used machine learning approach (model tr...
Efficient digital phased array beams require a high resolution timing vector. The timing coefficients cause speed bottleneck for FPGA implementation of beam forming in the HF frequency range. In this paper we present polyphase interpolator to overcome the speed limitation of FPGA implementation of digital beamforming (DBF) for ionospheric radar. The radar requires a constant phasing vector to s...
In this paper, we propose a multi-beam and multi-range (MBMR) radar with frequency modulated continuous wave (FMCW) waveform and digital beam forming (DBF) algorithm to cover a detection area of long range and narrow angle (150 m, ±10◦) as well as short range and wide angle (60 m, ±30◦) as a single 24 GHz sensor. The developed radar is highly integrated with multiple phased-array antennas, a tw...
Deciduous broadleaf forests (DBF) are an extremely widespread vegetation type in the global ecosystem and indicator of environmental change; thus, they require accurate phenological monitoring. However, there is still a lack systematic understanding sensitivity retrievals for DBF terms different spatial resolution data proxy indices. In this study, 79 globally distributed PhenoCam Network sites...
Satellites have different revisit frequencies (i.e., temporal resolutions), ranging from daily to monthly. The satellite suitable for accurately monitoring the phenology of deciduous broad-leaved forests (DBF) are not well-known. To fill this knowledge gap, study used MODIS Daily Nadir BRDF-Adjusted images simulate EVI time series with a wide range resolutions 52 days, investigate impacts frequ...
To establish the cutoff values for screening ENU-induced behavioral mutations, normal variations in mouse behavioral data were examined in home-cage activity (HA), open-field (OF), and passive-avoidance (PA) tests. We defined the normal range as one that included more than 95% of the normal control values. The cutoffs were defined to identify outliers yielding values that deviated from the norm...
