Pedestrian detection is a canonical problem for safety and security applications, and it remains a challenging problem due to the highly variable lighting conditions in which pedestrians must be detected. This article investigates several domain adaptation approaches to adapt RGB-trained detectors to the thermal domain. Building on our earlier work on domain adaptation for privacy-preserving pedestrian detection, we conducted an extensive experimental evaluation comparing top-down and bottom-up domain adaptation and also propose two new bottom-up domain adaptation strategies. For top-down domain adaptation, we leverage a detector pre-trained on RGB imagery and efficiently adapt it to perform pedestrian detection in the thermal domain. Our bottom-up domain adaptation approaches include two steps: first, training an adapter segment corresponding to initial layers of the RGB-trained detector adapts to the new input distribution; then, we reconnect the adapter segment to the original RGB-trained detector for final adaptation with a top-down loss. To the best of our knowledge, our bottom-up domain adaptation approaches outperform the best-performing single-modality pedestrian detection results on KAIST and outperform the state of the art on FLIR.

ABSTRACTWe have characterized a-Si:H initial layers for μc-Si:H nucleation by real time spectroscopic ellipsometry (SE) and infrared attenuated total reflection spectroscopy (ATR) to investigate the μc-Si:H formation mechanism. By performing Ar plasma treatment of a-Si:H layers, we confirmed a presence of a 2 monolayer thick sub-surface in a-Si:H layers. In the a-Si:H sub-surface that leads to the μc-Si:H nucleation, an important peak at ∼1937 cm−1 assigned to the SiHn complex was found in the ATR spectra. From H2 plasma treatment experiments, we proposed that this SiHn complex is formed by H insertion into strained Si-Si bonds. The SiHn complex formed in the a-Si:H sub-surface showed a clear relationship with the μc-Si:H nucleation. From these results, we conclude that the μc-Si:H nucleation occurs by the formation of the chemically active and flexible SiHn complexes in the 2 monolayer thick a-Si:H sub-surface.

Galena Electrode

The products of the electrochemical oxidation of potassium ethylxanthate have been identified by infrared analysis and microanalysis for the constituent elements. The current efficiency for the formation of diethyl dixanthogen depends on the nature of the electrode, and at 0.5 V was found to be 100, 98, 90, c. 50, and 0% for platinum, gold, copper, galena, and lead respectively. The remainder of the current passed at this potential resulted in the formation of the metal xanthate.� Dixanthogen is formed on lead electrodes only at potentials of > 1.0 V, where lead xanthate is unstable with respect to oxides of the metal. The lead xanthate produced on a galena electrode at pH 9.1 involves the release of thiosulphate ions. The formation of lead xanthate by this reaction, followed by its reduction to lead, is shown to change the surface characteristics of a galena electrode to those of lead. However, the formation and reduction of the initial layers which takes place on cycling the electrode potential does not change a galena surface and cannot involve loss of sulphur from the surface to the solution. This supports the conclusion that the chemisorbed xanthate monolayer is first covered by dixanthogen and that lead xanthate forms only when bulk layers are produced.

<p style='text-indent:20px;'>This work deals with a mathematical analysis of sodium's transport in a tubular architecture of a kidney nephron. The nephron is modelled by two counter-current tubules. Ionic exchange occurs at the interface between the tubules and the epithelium and between the epithelium and the surrounding environment (interstitium). From a mathematical point of view, this model consists of a 5<inline-formula><tex-math id="M1">\begin{document}$ \times $\end{document}</tex-math></inline-formula>5 semi-linear hyperbolic system. In literature similar models neglect the epithelial layers. In this paper, we show rigorously that such models may be obtained by assuming that the permeabilities between lumen and epithelium are large. We show that when these permeabilities grow, solutions of the 5<inline-formula><tex-math id="M2">\begin{document}$ \times $\end{document}</tex-math></inline-formula>5 system converge to those of a reduced 3<inline-formula><tex-math id="M3">\begin{document}$ \times $\end{document}</tex-math></inline-formula>3 system without epithelial layers. The problem is defined on a bounded spacial domain with initial and boundary data. In order to show convergence, we use <inline-formula><tex-math id="M4">\begin{document}$ {{{\rm{BV}}}} $\end{document}</tex-math></inline-formula> compactness, which leads to introduce initial layers and to handle carefully the presence of lateral boundaries. We then discretize both 5<inline-formula><tex-math id="M5">\begin{document}$ \times $\end{document}</tex-math></inline-formula>5 and 3<inline-formula><tex-math id="M6">\begin{document}$ \times $\end{document}</tex-math></inline-formula>3 systems, and show numerically the same asymptotic result, for a fixed meshsize.</p>
