Objective Shortage of organ donors, a critical challenge for treatment end-stage failure, has motivated the development alternative strategies to generate organs in vitro. Here, we aim describe hepatorganoids, which is liver tissue model generated by three-dimensional (3D) bioprinting HepaRG cells and investigate its functions vitro vivo. Design 3D bioprinted hepatorganoids (3DP-HOs) were constructed using bioink, according specific printing procedures. Liver 3DP-HOs detected after 7 days...

Currently, only 5% of thermoset carbon fiber reinforced polymer composites (CFRPs) are recycled into lower-value secondary products. Highly efficient closed-loop recycling both resin and is a major challenge. Here, we report sustainable approach for the from CFRPs. Thiol-functionalized (TCF) obtained by functionalization with thiol-ended hyperbranched polymer, then an epoxy-ended degradable (HT3) used to prepare HT3/TCF composites, which show considerable acid resistance mechanical...

The integration of thermoelectric (TE) device on fabrics is a challenge. Instead using adhesive tape to fix traditional filmlike TE devices onto the fabrics, which sacrifices breathability here we report flexible fiber based poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS)/tellurium nanowires (Te NWs) composites, can be woven and integrated into fabric directly. fibers have tunable content orientation Te NWs also potential scaled up wet-spinning process. exhibit desirable...

Exploring historical measurement data-driven health monitoring schemes for roller bearings is a current research hotspot. In engineering practice, the type of fault data obtained often unknown and requires expensive costs to be annotated. However, most intelligent diagnostic methods are based on assumption that labeled sufficient, so as effectively establish nonlinear mapping relationship between signals status. For this issue, newly diagnosis method semi-supervised matrixized graph...

Abstract: Cell-penetrating peptides (CPPs) as small molecular transporters with abilities of cell penetrating, internalization, and endosomal escape have potential prospect in drug delivery systems. However, a bottleneck hampering their application is the poor specificity for cells. By utilizing function hydration shell polyethylene glycol (PEG) acid sensitivity hydrazone bond, we constructed kind CPP-modified pH-sensitive PEGylated liposomes (CPPL) to improve selectivity these tumor...

Decades of research in machine learning have given us powerful tools for making accurate predictions. But when used social settings and on human inputs, better accuracy does not immediately translate to outcomes. This may be surprising that conventional frameworks are designed express societal preferences -- let alone promote them. position paper argues is currently missing, can gain much from incorporating, a proper notion welfare. The field welfare economics asks: how should we allocate...

Motivated by the recent popularity of machine learning training services, we introduce a contract design problem in which provider sells service that results an outcome uncertain quality for buyer. The seller has set actions lead to different distributions over outcomes. We focus on setting ability commit action and buyer is free accept or reject after seeing its realized quality. propose two-stage payment scheme where designs menu contracts, each specifies action, upfront price vector...

The stability of rock slope-footing systems is influenced by various factors, including slope geometry, mass strength, load properties, and foundation placement. Previous studies on the ultimate bearing capacity strip footings slopes have primarily focused geometry with limited attention to effects embedment depth inclined loads. This study employs finite element limit analysis (FELA) method examine influence inclination angles varying depths slopes. Additionally, an image recognition...

We prove strong ${\mathbb {NP}}$ -completeness for the four variants of caching with multi-size pages. These are obtained by choosing either fault cost or bit model, and combining it a forced an optional policy. This resolves two questions in area paging that were open since 1990s.

We propose FusedCache, a two-level set-associative Racetrack memory (RM) cache design that utilizes RM's high density for providing fast uniform access at one level, and non-uniform the next. FusedCache is well suited private L1/L2 caches enforcing alignment of L1 data with RM points remaining non-aligned serving as L2. It uses traditional LRU eviction misses. Promotion demotion between L2 are performed through shifts and, when necessary, background swap operations. These operations do not...

Specific emitter identification (SEI) can verify the identity of emitters and plays an important role in a wide range military civilian fields. Most recently, there has been great interests applying deep learning techniques for SEI. However, vast majority existing work limits SEI to closed-set classification, where networks only perform classification limited set known emitters. These algorithms are not capable handling transmitters that appear outside closed set, compromising security...
