Abstract: A method for accelerated decision tree execution in a processor of a digital system is provided that includes receiving at least some attribute values of a plurality of attribute values of a query for the decision tree in a pre-processing component, evaluating the received attribute values in the pre-processing component according to first early termination conditions corresponding to a first decision to determine whether or not the received attribute values fulfill first early termination conditions, and querying the decision tree with the plurality of attribute values when the received attribute values do not fulfill the first early termination conditions.

Moreover, 14C dates on taiga vole indicate vegetated conditions in some areas of the bottleneck by at least 14,870 years ago (59), and a poplar fragment from Boone Lake in the uplands of northwestern Alberta (60) indicates the presence of trees by at least 13,500 years ago. These data suggest a vegetated Corridor well before minimum age estimates of ecological viability derived from the presence of bison and horse at 13,100 years ago (61, 62) and plant macrofossils and environmental DNA at Charlie Lake at 12,600 years ago (63) (Fig. 3). Beyond the IFC region, other researchers have identified alternative inland routes through unglaciated Cordilleran areas (64–66), where resources such as sheep may have persisted through the LGM (67). Collectively, these data indicate that the Corridor and adjacent interior areas could have emerged as a potential route for ancestral Native Americans as early as 15,000 to 14,000 years ago, and that movements in either direction along the entire length of the Corridor were feasible well before Clovis times (12, 68). Both pathways, interior and coastal, allow viable hypotheses that need not be mutually exclusive and should be further tested.

MGT nanocomposites were prepared through a layer-by-layer coating process (23). Magnetic Fe3O4 NPs were prepared through modified solvothermal reaction by reduction of FeCl3 (23). As shown in transmission electron microscopy (TEM) images (fig. S1A), the as-prepared Fe3O4 NPs were highly uniform with diameters of 120 ± 5 nm. We observed a well-resolved lattice fringe with an interplanar distance of 0.26 nm for Fe3O4, which corresponds to the (311) plane of magnetite (fig. S1B). In addition, hysteresis loops of Fe3O4 particles in fig. S1C indicate high-performance magnetic properties without remanence or coercivity at 300 K. We coated Fe3O4 NPs with GO through electrostatic adsorption with the linkage of polydimethyldiallylammonium chloride (PDDA) to produce magnetic Fe3O4@GO (MG). Scanning electron (SEM) micrographs (Fig. 2A) show that Fe3O4 NPs were effectively coated with GO. TEM images show that the irregular shapes of the nanocomposites were highly dispersed with diameters of 150 to 250 nm (Fig. 2B). Then, we prepared the uniform porous TiO2 shell via a versatile kinetics-controlled coating method to produce MGT nanocomposites. We observed the ternary heterostructure of MGT (size, 200 to 400 nm) coated by the aggregated TiO2 NPs (~8 nm) and with uniform pores (~5 nm; Fig. 2, C and D). N2 sorption isotherms (Fig. 2E) of the nanocomposites after calcination show typical type IV curves with distinct hysteresis loops close to the H1 type. The Brunauer-Emmett-Teller surface area and the pore volume of the as-prepared nanostructures were calculated to be as high as 105 m2 g−1 and 0.16 cm3 g−1, respectively. The corresponding pore size distribution curves (Fig. 2F) derived from the adsorption branches of the isotherms using the Barrett-Joyner-Halenda method show a sample pore size of ~4.3 nm, which was similar to that obtained from the SEM image. A high-resolution TEM (HR-TEM) image [Fig. 2G (III)] shows that the TiO2 NPs were crystallized with a well-resolved lattice fringe with an interplanar distance of 0.24 nm, which corresponds to the (103) plane of anatase (24). We carried out energy dispersive spectroscopy (EDS) to characterize the elemental composition and the structural relationship of the nanostructures from every step obtained (Fig. 2G). It was clear that Fe was located at the center of nanocomposites, while the shell contained C and Ti, which were well separated from each other. X-ray diffraction (XRD) fitted well to those of Fe3O4, GO, and TiO2 bulk phases (Fig. 2H). The diffraction peaks of Fe3O4 were ascribed to the (220), (311), and (440) planes. After Fe3O4 was coated with GO and TiO2, two additional diffraction peaks were observed at 21.2° and 43.3°, which should be ascribed to GO. Several new diffraction peaks appeared at 25.3°, 37.8°, 38.6°, 48.1°, 53.9°, and 55.1°, assigned to the (101), (004), (112), (200), (105), and (211) planes of anatase-phase TiO2, respectively (25, 26), confirming the successful preparation of MGT. We further used Raman and Fourier transform infrared (FTIR) spectroscopy to characterize the as-prepared MGT. As depicted in Fig. 2I, three distinct peaks at 397, 518, and 640 cm−1 in the Raman spectrum of MGT were observed, indicating the presence of anatase-phase TiO2 (26, 27). In the FTIR spectra of MGT (Fig. 2J), two additional infrared bands assigned to Ti–O–C at 1680 cm−1 and Ti–O–H stretching vibration at 3260 cm−1 were observed (28). Both Raman and FTIR results indicated that the MGT nanocomposites were successfully synthesized. The stepwise assembly of MGT was also monitored by microeletrophoresis measurements whose results were expressed as ζ-potentials (fig. S1D). Because of the superparamagnetic properties of the magnetic cores of MGT (Fig. 2K), the MGT nanocomposites were conveniently separated from the reaction solution after the photodegradation treatment upon application of an extended magnetic field. Moreover, it is known that TiO2 shows absorption ranging from 200 to 350 nm. On the other hand, absorbance of MGT nanocomposites extended to the visible region (400 to 600 nm) because of the conjugation of TiO2 with visible GO (fig. S1E) (26). Figure S2 shows the Raman spectra of copper phthalocyanine (CuPc) before and after illumination under visible light (460 nm < λ < 700 nm, 1000 W) on MGT nanocomposites. The intensity of the Raman spectra of CuPc sharply decreased after illumination by visible light for 90 min, revealing that CuPc was significantly photodegraded (26). In contrast, we obtained negligible changes for MT NPs (fig. S2, B and C). Accordingly, after five cycles of enrichment followed by illumination, the SERS activity of MGT remained more than 98% (fig. S2D), confirming the good recyclability of MGT. Considering the photocatalytic activity of MGT under the visible light region, we investigated the Raman signal reproducibility of MGT in fig. S3. After irradiating 15 times with an exposure time of 1 s, the Raman intensity of CuPc remained approximately 97%, indicating the high stability and reproducibility of MGT substrates. Besides, we measured the surface wettability of MGT through contact angle. As shown in fig. S1F, MGT showed hydrophilic properties with an MGT contact angle of 41° ± 2°, which is suitable for further bio-applications.

Abstract: Methods, systems, and computer program products for generating recommendations. In response to receiving a request, the system generates a plurality of suggested recommendations for both a first bound and a second bound of a trip. The system stores the suggested recommendations corresponding to the first bound and the second bound in a memory, where the suggested recommendations corresponding to the second bound coincide to a subset of the suggested recommendations corresponding to the first bound published for display. The system publishes the suggested recommendations corresponding to the first bound for display to a user. In response to receiving an input that indicates a selected recommendation for the first bound, the system determines whether the selected recommendation is one of the subset of the suggested recommendations corresponding to the first bound.
