Abstract Collisional orogeny is characterized by deep subduction of continental crust and major crustal thickening, leading to high-pressure/high-temperature metamorphism anataxis the subducted crust. Since conductive heating large slabs cold, a slow process, temperature that high enough generate significant partial melting can take tens millions years. Where spatial temporal relationships are obscured due later modification (e.g. post-collisional rifting), peak magmatism may be interpreted...

Abstract Identifying source orogens for syn-orogenic sediments in dispersed fragments of a supercontinent provides key information on the tectonic evolution involved assembly and paleogeographic reconstruction. An approach using U-Pb geochronology trace elements multiple detrital minerals including zircon, rutile, apatite, monazite has major advantages over zircon studies alone. Application this multi-pronged to Ediacaran Cambrian clastic sedimentary rocks from West Cathaysia terrane South...

Abstract Light fields carry abundant information, including intensity, spectral, and polarization, which have been widely studied in imaging, quantum technologies, communications. However, conventional cameras are typically limited to capturing intensity alone, neglecting other crucial dimensions of restricts their application scope. Disordered nanostructures significantly enhance light scattering absorption, thereby broadening the spectral response range enabling sensitive detection...

Glioblastoma stem cells (GSCs) are the initiating in glioblastoma multiforme (GBM) and contribute to resistance of GBM chemotherapy radiation. In present study, we investigated effects cardamonin (3,4,2,4-tetrahydroxychalcone) on self-renewal apoptosis GSCs, if its action is associated with signal transducer activator transcription 3 (STAT3) pathway. CD133(+) a kind GSCs line, was established from human tissues. Cardamonin inhibited proliferation induced CD133+ GSCs. The proapoptotic...

Bis (2,3-dibromo-4,5-dihydroxy-phenyl)-methane (BDDPM) is a natural bromophenol compound derived from marine algae. Previous reports have shown that BDDPM possesses antimicrobial activity. In the present study, we found has cytotoxic activity on wide range of tumor cells, including BEL-7402 cells (IC50 = 8.7 μg/mL). Further studies prior to onset apoptosis, induces cell detachment by decreasing adherence extracellular matrix (ECM). Detachment experiments treatment with low concentrations...

The novel bromophenol derivative, 3-(3-bromo-5-methoxy-4-(3-(piperidin-1-yl)propoxy)benzylidene)-N-(4-bromophenyl)-2-oxoindoline-5-sulfonamide (BOS-93), was synthesized in the CAS Key Laboratory of Experimental Marine Biology, Institute Oceanology, Chinese Academy Sciences (Qingdao, China). studies have demonstrated that it could induce apoptosis and autophagy human A549 lung cancer cells, also inhibit tumor growth xenograft models.

This letter introduces a novel two-pass structural grouping algorithm and casts visual tracking as foreground superpixels problem. In the first step, pairwise superpixel is conducted in four orientations. Grouping prototypes containing prior information of background are generated to determine whether any pair neighboring should be grouped together. second selected by step into single region which serves object region. The proposed method has two benefits over state-of-the-art ones. First,...

From the classical selective repeat ARQ (Automatic Repeat-reQuest) protocol, a quantum synchronous communication protocol in data link layer is presented by utilizing intrinsic characteristics of mechanics. The proposed divides into preparation and send stages, where message sent via channel distribution EPR (Einstein-Podolsky-Rosen) pairs are supposed to be accomplished at stage. performances several protocols compared analyzed from aspects throughput utilization ratio channel. It shown...

Abstract One-dimensional photonic bandgap crystal (PBC) lasers have demonstrated ultra-low vertical divergence and record brightness; however, their future development is limited by lateral beam quality. In this paper, a fishbone microstructure proposed to control the modes in broad-area PBC lasers. The findings reveal that introduction of improves full width at half maximum far field 22.2% increases output power small extent. detailed measurements show parameter product decreases 15.9%.

In this paper, we present how the LTL (Linear Temporal Logic) language can be used to specify security protocols and discuss analysis process using LTL.

We also extend use knowledge reason about situations where an agent is important, change may occur in over time. end, some possible directions for future work.

We report the performance of a high-power vertical-cavity surface-emitting laser (VCSEL) with an extra Au layer. By using layer, far-field divergence angle from 600-μm diameter VCSEL device is suppressed 30/spl deg/ to 15/spl deg/, and no strong sidelobe observed in pattern. There slight drop optical output power due introduction improving packaging method, produces maximum continuous-wave 1.95 W lasing wavelength 981.5 nm. The aging test carried out under constant current mode at 60/spl...

With the rapid development of artificial intelligence technology, human‐computer interaction, as core virtual reality system, has become an increasingly important part modern science and technology products. At present, interaction is mainly based on contact, which must be completed through direct contact between hand receiving equipment, rather than indirect equipment. Direct can not give full play to advantages flexible human hand, so gesture recognition becomes extremely in interaction....
