Learning Visual Clothing Style with Heterogeneous Dyadic Co-Occurrences (2015)

With the rapid proliferation of smart mobile devices, users now take millions of photos every day. These include large numbers of clothing and accessory images. We would like to answer questions like 'What outfit goes well with this pair of shoes?' To answer these types of questions, one has to go beyond learning visual similarity and learn a visual notion of compatibility across categories. In this paper, we propose a novel learning framework to help answer these types of questions. The main idea of this framework is to learn a feature transformation from images of items into a latent space that expresses compatibility. For the feature transformation, we use a Siamese Convolutional Neural Network (CNN) architecture, where training examples are pairs of items that are either compatible or incompatible. We model compatibility based on co-occurrence in large-scale user behavior data, in particular co-purchase data from Amazon.com. To learn cross-category fit, we introduce a strategic method to sample training data, where pairs of items are heterogeneous dyads, i.e., the two elements of a pair belong to different high-level categories. While this approach is applicable to a wide variety of settings, we focus on the representative problem of learning compatible clothing style. Our results indicate that the proposed framework is capable of learning semantic information about visual style and is able to generate outfits of clothes, with items from different categories, that go well together.

[Long-term results of open parietal pleurectomy in treatment of recurrent spontaneous pneumothorax]. (1993)

The open parietal pleurectomy is an effective treatment of recurrent or persistent spontaneous pneumothorax with a low recurrency rate of 3.3% in our series. The long-term course reveals very good functional results. A relatively high number of patients complains about chest wall pain or a painful thoracotomy scar. Also remarkable is the rate of dissatisfaction with the cosmetic result of the thoracotomy. Regarding both complaints thoracoscopic pleurectomy should be able to improve the results and the acceptance of this operation.
Characterization of Knock in a Spark-Ignition Engine (1989)

&lt;div class="htmlview paragraph"&gt;Spark-ignition engine knock was characterized in terms of when during the engine cycle and combustion process knock occurred and its magnitude or intensity. Cylinder pressure data from a large number of successive individual cycles were generated from a single-cylinder engine of hemispherical chamber design over a range of operating conditions where knock occurred in some or all of these cycles. Mean values and distributions of following parameters were quantified: knock occurrence crank angle, knock intensity, combustion rate and the end-gas thermodynamic state. These parameters were determined from the cylinder pressure data on an individual cycle basis using a mass-burn-rate analysis. The effects of engine operating variables on these parameters were studied, and correlations between these parameters were examined.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;The individual cycle knock occurrence crank angle correlates well with the combustion rate or a thermodynamic parameter representing the end-gas temperature history on an individual cycle basis. But the individual cycle knock intensity does not correlate with any of the relevant variables measured although the mean knock intensity did correlate well with the mean unburned fuel fraction at knock. This lack of correlation on an individual cycle basis is thought to be due to differences in the end-gas temperature and species concentration distributions, and differences in the geometry and location of the end-gas region, cycle-by-cycle.&lt;/div&gt;
Oligosaccharides derived from Lycium barbarum ameliorate glycolipid metabolism and modulate the gut microbiota community and the faecal metabolites in a type 2 diabetes mouse model: metabolomic bioinformatic analysis (2022)

Herein, we assessed the effects of <i>Lycium barbarum</i> oligosaccharides (LBO) on the intestinal microenvironment of a type 2 diabetes (T2D) mouse model through gut microbiome and metabolomics analysis. We set high (300 mg kg<sup>-1</sup>), medium (200 mg kg<sup>-1</sup>), and low (100 mg kg<sup>-1</sup>) doses of LBO for intervention once a day for 4 weeks. The results showed that the intervention effect of the medium-dose group was the most significant. It reduced the symptoms of hyperglycemia, inflammation, insulin resistance, and lipid accumulation in the T2D mouse model. It restored the structure of damaged tissues and cells, such as the pancreas, liver, and kidneys. LBO increased the relative abundance of beneficial bacteria, such as <i>Lactobacillus</i>, <i>Bacteroides</i>, <i>Prevotella</i>, and <i>Akkermansia</i>, and maintained intestinal barrier integrity. The faecal metabolic map showed that the contents of glycogen amino acids, such as proline, serine, and leucine, increased. The contents of cholic, capric, and dodecanoic acid decreased. In summary, we may suggest that LBO can be used as a prebiotic for treating T2D.

SUSCEPTIBILITY OF THE LESSER MEALWORM, ALPHITOBIUS DIAPERINUS (COLEOPTERA: TENEBRIONIDAE) TO THE ENTOMOGENOUS NEMATODES STEINERNEMA FELTIAE, S. GLASERI (STEINERNEMATIDAE) AND HETERORHABDITIS HELIOTHIDIS (HETERORHABDITIDAE) (1985)

The infectivity of Steinernema feltiae, S. glaseri and Heterorhabditis heliothidis for early-stage larvae, late-stage larvae, pupae and adults of the lesser mealworm were evaluated under different habitat conditions. When confined in petri dishes with nematode-treated filter paper, all beetle stages were highly susceptible to parasitism by S. feltiae, with LD50 values ranging from 9 to 56 nematodes per host Early-stage larvae (LD50 = 26) and pupae (LD50 = 36) were more susceptible than late-stage larvae (LD50 = 1,791) and adults (LD50 = 724) to H. heliothidis. Only adult beetles (LD50 = 714) were susceptible to S. glaseri. Late-stage beetle larvae were more susceptible to S. feltiae in rearing medium (LD50 = 24), broiler litter (LD50 = 2 58) and poultry manure (LD50 = 212) than to H. heliothidis, which caused less than 50% mortality at all dose rates in these substrates. Adults were less susceptible than larvae in these substrates, and mortality only exceeded 50% in litter treated with S. feltiae (LD50 = 971). Late-stage larvae were highly susceptible to both S. feltiae and H. heliothidis in sandy loam and clay soils, with LD50's ranging from 1 to 14 nematodes per larva. Pupal mortality was higher in sandy loam (S. feltiae LD50 = 46, H. heliothidis LD50 = 444) than in clay soil (S. feltiae LD50 = 95, H. heliothidis LD50 = 5,796).

Impact of adipose tissue or umbilical cord derived mesenchymal stem cells on the immunogenicity of human cord blood derived endothelial progenitor cells (2017)

The application of autologous endothelial progenitor cell (EPC) transplantation is a promising approach in therapeutic cardiovascular diseases and ischemic diseases. In this study, we compared the immunogenicity of EPCs, adipose tissue (AD)-derived mesenchymal stem cells (MSCs) and umbilical cord (UC)-derived MSCs by flow cytometry and the mixed lymphocyte reaction. The impact of AD-MSCs and UC-MSCs on the immunogenicity of EPCs was analyzed by the mixed lymphocyte reaction and cytokine secretion in vitro and was further tested by allogenic peripheral blood mononuclear cell (PBMC) induced immuno-rejection on a cell/matrigel graft in an SCID mouse model. EPCs and AD-MSCs express higher levels of MHC class I than UC-MSCs. All three kinds of cells are negative for MHC class II. UC-MSCs also express lower levels of IFN-γ receptor mRNA when compared with EPCs and AD-MSCs. EPCs can stimulate higher rates of proliferation of lymphocytes than AD-MSCs and UC-MSCs. Furthermore, AD-MSCs and UC-MSCs can modulate immune response and inhibit lymphocyte proliferation induced by EPCs, mainly through inhibition of the proliferation of CD8+ T cells. Compared with UC-MSCs, AD-MSCs can significantly improve vessel formation and maintain the integrity of neovascular structure in an EPC+MSC/matrigel graft in SCID mice, especially under allo-PBMC induced immuno-rejection. In conclusion, our study shows that AD-MSC is a powerful candidate to minimize immunological rejection and improve vessel formation in EPC transplantation treatment.
Application of curing compounds on concrete pavements (2017)

The concrete hardening process should take place in a manner that provides optimum hydration development, which can be achieved through proper curing practices. Since curing of concrete is essential at controlling its mechanical and durability performance during service, the aim of this research was to assess the effect of different curing compound applications on the behavior of field pavement, and thus projecting its long-term durability. The study involved experiments on cores extracted from recently constructed pavement sections in comparison to corresponding specimens produced from similar concrete under laboratory conditions. Absorption, rapid chloride penetrability, thermogravimetry, mercury intrusion porosimetry, and scanning electron microscopy tests were conducted on cores and specimens to study the effect of the different curing compound applications. The overall trends indicate that applying a thorough coat of curing compound is essential to ensure moisture retention in concrete for efficient hydration reactions and microstructural development.
Prostasin expression is regulated by airway surface liquid volume and is increased in cystic fibrosis (2008)

Airway surface liquid (ASL) absorption is initiated by Na+ entry via epithelial Na+ channels (ENaC), which establishes an osmotic gradient that drives fluid from the luminal to serosal airway surface. We and others have recently reported that a protease/anti-protease balance regulates ENaC in human airway epithelial cells (HAEC) and provides a mechanism for autoregulation of ASL volume. In cystic fibrosis (CF), this balance is disturbed, leading to constitutive proteolytic activation of ENaC and the pathological Na+ hyperabsorption characteristic of this airway disease. Prostasin is a glycosylphosphatidylinositol-anchored serine protease that activates ENaC and is expressed on the surface epithelium lining the airway. In this report we present evidence that prostasin expression is regulated by the ASL volume, allowing for increased proteolytic activation of ENaC when the ASL volume is high. Prostasin activity is further regulated by the cognate serpin protease nexin-1 (PN-1), which is expressed in HAEC and inhibits Na+ absorption by forming an inactive complex with prostasin and preventing the proteolytic processing of prostasin. Whereas these mechanisms regulate prostasin expression in response to ASL volume in non-CF epithelia, HAEC cultured from CF patients express >50% more prostasin on the epithelial surface. These findings suggest that a proteolytic cascade involving prostasin, an upstream prostasin-activating protease, and PN-1 regulate Na+ absorption in the airway and that abnormal prostasin expression contributes to excessive proteolytic activation of ENaC in CF patients.
Biodegradable Polymers from Renewable Sources:  Rheological Characterization of Hemicellulose-Based Hydrogels (2005)

Hemicellulose-based hydrogels were prepared by radical polymerization of 2-hydroxyethyl methacrylate or poly(ethylene glycol) dimethacrylate with oligomeric hydrosoluble hemicellulose modified with well-defined amounts of methacrylic functions. The polymerization reaction was carried out in water at 40 degrees C using a redox initiator system. The hydrogels were in general elastic, soft, and easily swellable in water. Their viscoelastic properties were determined by oscillatory shear measurements on 2 mm thick hydrogels under a slight compression to avoid slip, over the frequency range 10(-1) to 10(2). The rheological characterization indicated that the elastic response of the hydrogels was stronger than the viscous response, leading to the conclusion that the hydrogel systems displayed a predominantly solid-like behavior. The curves showed an increase in shear storage modulus with increasing cross-linking density. The nature of the synthetic comonomer in the hemicellulose-based hydrogels also influenced the shear storage modulus. Comparison of hemicellulose-based hydrogels with pure poly(2-hydroxyethyl methacrylate) hydrogels showed that their behaviors were rather similar, demonstrating that the synthetic procedure made it possible to prepare hemicellulose-based hydrogels with properties similar to those of pure poly(2-hydroxyethyl methacrylate) hydrogels.
Statistical bellman-ford algorithm with an application to retiming (2006)

Process variations in digital circuits make sequential circuit timing validation an extremely challenging task. In this paper, a Statistical Bellman-Ford (SBF) algorithm is proposed to compute the longest path length distribution for directed graphs with cycles. Our SBF algorithm efficiently computes the statistical longest path length distribution if there exist no positive cycles or detects one if the circuit is likely to have a positive cycle. An important application of SBF is Statistical Retiming based Timing Analysis (SRTA), where SBF is used to check for the feasibility of a given target clock period distribution for retiming. Our gate and wire delay distribution model considers several high-impact intra-die process parameters and accurately captures the spatial and reconvergent path correlations. The Monte Carlo simulation is used to validate the accuracy of our SBF algorithm. To the best of our knowledge, this is the first paper that propose the statistic version of the longest path algorithm for sequential circuits
Optimizing stereo‐to‐multiview conversion for autostereoscopic displays (2014)

Abstract We present a novel stereo‐to‐multiview video conversion method for glasses‐free multiview displays. Different from previous stereo‐to‐multiview approaches, our mapping algorithm utilizes the limited depth range of autostereoscopic displays optimally and strives to preserve the scene's artistic composition and perceived depth even under strong depth compression. We first present an investigation of how perceived image quality relates to spatial frequency and disparity. The outcome of this study is utilized in a two‐step mapping algorithm, where we (i) compress the scene depth using a non‐linear global function to the depth range of an autostereoscopic display and (ii) enhance the depth gradients of salient objects to restore the perceived depth and salient scene structure. Finally, an adapted image domain warping algorithm is proposed to generate the multiview output, which enables overall disparity range extension.
Type-specific and cross-reactive antibodies induced by human papillomavirus 31 L1/L2 virus-like particles (2007)

The aim of this study was to determine whether antibodies induced by human papillomavirus (HPV) type 31 L1/L2 virus-like particles (VLPs) could cross-react with VLPs of the closely related HPV-16 and distantly related HPV-11, and to investigate the potential role of the L2 protein in L1/L2 VLPs in inducing cross-neutralizing antibodies. Antisera were prepared from rabbits immunized with intact or denatured HPV-31 L1/L2 VLPs. Cross-reaction and cross-neutralization were analysed by Western blotting and ELISA, and by haemagglutination inhibition, respectively. Western blotting results showed that H31 L1/L2 (D) antiserum (antiserum from a rabbit immunized with denatured HPV-31 L1/L2 VLPs) could cross-react with the L1 protein of HPV-11 and -16. HPV-31 L1/L2 VLP antiserum showed strong cross-reaction with and cross-neutralization of HPV-16 VLPs, but this was significantly less with HPV-11 VLPs. In addition, the cross-neutralizing activity against HPV-16 L1/L2 VLPs was slightly higher than that against HPV-16 L1 VLPs, although the difference was not statistically significant. Epitope-blocking ELISA showed that mAb H16.V5 could partially inhibit the cross-reaction of HPV-31 L1/L2 VLP antiserum with HPV-16 L1/L2 VLPs. These results suggested that (i) H31 L1/L2 (D) antiserum could cross-react with L1 protein from both closely related and distantly related HPV types, but HPV-31 L1/L2 VLP antiserum could only cross-neutralize closely related HPV types, (ii) surface-exposed epitopes of the L2 protein in L1/L2 VLPs may induce only low titres of cross-neutralizing antibodies and (iii) certain epitopes that cross-reacted with HPV-31 L1/L2 VLP antiserum are located close to the epitopes recognized by mAb H16.V5. These findings may provide suggestions for the design of multivalent VLP vaccines.
Combining TLS and TPMs to Achieve Device and User Authentication for Wi-Fi and WiMAX Citywide Networks (2008)

Deploying large-scale wireless citywide networks with strong authentication mechanisms has received considerable interest in industry and academic circles. In this paper, we present modified Transport Layer Security (TLS) protocols which leverage Trusted Platform Module (TPM) technologies to achieve both user and device authentication. The first protocol leverages TPM attestation capabilities, while the other uses TPM sealed storage to achieve our goals. The proposed user and device authentication schemes can provide mutual proof between supplicants and servers not only on Wi-Fi and WiMAX interworked wireless cities, but also on any heterogeneous wireless networks which is based on the Extensible Authentication Protocol.
Simulation to Scaled City: Zero-Shot Policy Transfer for Traffic Control via Autonomous Vehicles (2018)

Using deep reinforcement learning, we train control policies for autonomous vehicles leading a platoon of vehicles onto a roundabout. Using Flow, a library for deep reinforcement learning in micro-simulators, we train two policies, one policy with noise injected into the state and action space and one without any injected noise. In simulation, the autonomous vehicle learns an emergent metering behavior for both policies in which it slows to allow for smoother merging. We then directly transfer this policy without any tuning to the University of Delaware Scaled Smart City (UDSSC), a 1:25 scale testbed for connected and automated vehicles. We characterize the performance of both policies on the scaled city. We show that the noise-free policy winds up crashing and only occasionally metering. However, the noise-injected policy consistently performs the metering behavior and remains collision-free, suggesting that the noise helps with the zero-shot policy transfer. Additionally, the transferred, noise-injected policy leads to a 5% reduction of average travel time and a reduction of 22% in maximum travel time in the UDSSC.
