A Multi-task Selected Learning Approach for Solving 3D Flexible Bin Packing Problem (2018)

A 3D flexible bin packing problem (3D-FBPP) arises from the process of warehouse packing in e-commerce. An online customer's order usually contains several items and needs to be packed as a whole before shipping. In particular, 5% of tens of millions of packages are using plastic wrapping as outer packaging every day, which brings pressure on the plastic surface minimization to save traditional logistics costs. Because of the huge practical significance, we focus on the issue of packing cuboid-shaped items orthogonally into a least-surface-area bin. The existing heuristic methods for classic 3D bin packing don't work well for this particular NP-hard problem and designing a good problem-specific heuristic is non-trivial. In this paper, rather than designing heuristics, we propose a novel multi-task framework based on Selected Learning to learn a heuristic-like policy that generates the sequence and orientations of items to be packed simultaneously. Through comprehensive experiments on a large scale real-world transaction order dataset and online AB tests, we show: 1) our selected learning method trades off the imbalance and correlation among the tasks and significantly outperforms the single task Pointer Network and the multi-task network without selected learning; 2) our method obtains an average 5.47% cost reduction than the well-designed greedy algorithm which is previously used in our online production system.
Cuphea growth and development: responses to temperature. (2002)

Species from the genus Cuphea, Lythraceae, are known to produce seed rich in medium chain fatty acids (MCFA), which are important feed-stocks in the manufacturing of soaps and detergents and numerous other related products (Thompson 1984). In the US there are no crops grown that serve as an economical replace-ment of MCFA. Consequently, the US chemical industry imports most MCFA as coconut (Cocos nucifera L.)
Grain boundary dynamics under mechanical annealing in two-dimensional colloids (2004)

Two-dimensional (2D) colloids embedded in a soap film are employed to study the structures and dynamics of grain boundaries (GBs). While a soap film is drawn vertically from a concentrated bulk suspension, the colloidal particles self-assemble to form polycrystalline structures with a typical grain size of about 100 lattice spaces. Studies of these grain boundaries reveal that the GB lines are faceted at "atomic" scale, leading to a constant energy per unit length along each line. The measured GB energy as a function of misfit angle is in agreement with Reed-Shockley's theoretical predictions. When an external mechanical vibration is applied to the bulk suspension, the grain boundaries are observed to migrate and grains to rotate under the stress field induced by the vibration. The total length of the grain boundaries is found to diminish logarithmically with time, with the rate constant being a function of the excitation strength. This phenomenon, called "mechanical annealing," provides a robust means to grow large 2D single-domain crystals.
A complete model of E/sup 2/PROM memory cells for circuit simulations (2003)

E/sup 2/PROM memory devices are widely used in embedded applications. For an efficient design flow, a correct modeling of these memory cells in every operation condition becomes more and more important, especially due to power consumption limitations. Although E/sup 2/PROM cells have being used for a long time, very few compact models have been developed. Here, we present a complete compact model based on an original procedure to calculate the floating gate potential in DC conditions, without the need of any capacitive coupling coefficient. This model is designed as a modular structure, so to simplify program/erase and reliability simulations. Program/erase and leakage currents are included by means of simple voltage-controlled current sources implementing their analytical expression. It can be used to simulate memory cells both during read operation (DC conditions) and during program and erase (transient conditions) giving always very accurate results. We show also that, provided there are good descriptions of degradation mechanisms, the same model can be used also for reliability simulations, predicting charge loss due to tunnel oxide degradation.
The Influence of Two Surfactants on Infiltration into a Water-Repellent Soil (2002)

Water-repellency which affects infiltration, evaporation, erosion, and other water transfer mechanisms through soil has been observed under several natural conditions throughout the world. Surfactants can be used to mitigate the consequences of soil water repellency. The infiltration rates of two surfactants applied at concentrations of 500, 1000, 3000, and 5000 mg L−1 were measured on laboratory columns of sand treated to create a stable water-repellent system. All of these surfactant solutions had a surface tension equal to 0.035 N m−1 Drop-penetration times (DPT) of these solutions were also measured for these solutions. An aqueous ethanol solution with an identical surface tension as the surfactant solutions was also used. The DPT decreased and the infiltration rate increased as the surfactant solution concentration increased. The results are explained by adsorption of surfactant which caused an increase in surface tension of the solution. Adsorption of surfactants enhanced soil rewetting so that treated columns that were dried had high subsequent infiltration rates with water. Because the adsorption of surfactants greatly affects infiltration, prescription of surfactant treatment on a theoretical basis is not feasible. Although some basic concepts can be established, the utility of surfactants in managing water repellent systems will depend on empirical observations.
[Progress in the method of tibial prosthesis rotation alignment in total knee arthroplasty]. (2020)

The surgeon should master the methods of rotation and alignment of tibial prosthesis, make preoperative plans, select appropriate alignment methods for different patients, and achieve individualization. Meanwhile, several anatomical landmarkers should be referred to properly during the operation, which can be used to detect the correct placement of tibial prosthesis and avoid large rotation error.
Optimizations enabled by a relational data model view to querying data streams (2002)

We postulate that the popularity and efficiency of SQL for querying relational databases makes the language a viable solution to retrieving data from data streams. In response, we have developed a system, dQUOB, that uses SQL queries to extract data from streaming data in real time. The high performance needs of applications such as scientific visualization motivates our search for optimizations to improve query evaluation efficiency. The purpose of this paper is to discuss the unique optimizations we have realized by a database point of view to streaming data and to show that the enhanced conceptual model of viewing data streams as relations has reasonable overhead.
An improved i-vector extraction algorithm for speaker verification (2015)

Over recent years, i-vector-based framework has been proven to provide state-of-the-art performance in speaker verification. Each utterance is projected onto a total factor space and is represented by a low-dimensional feature vector. Channel compensation techniques are carried out in this low-dimensional feature space. Most of the compensation techniques take the sets of extracted i-vectors as input. By constructing between-class covariance and within-class covariance, we attempt to minimize the between-class variance mainly caused by channel effect and to maximize the variance between speakers. In the real-world application, enrollment and test data from each user (or speaker) are always scarce. Although it is widely thought that session variability is mostly caused by channel effects, phonetic variability, as a factor that causes session variability, is still a matter to be considered. We propose in this paper a new i-vector extraction algorithm from the total factor matrix which we term component reduction analysis (CRA). This new algorithm contributes to better modelling of session variability in the total factor space. We reported results on the male English trials of the core condition of the NIST 2008 Speaker Recognition Evaluation (SREs) dataset. As measured both by equal error rate and the minimum values of the NIST detection cost function, 10–15 % relative improvement is achieved compared to the baseline of traditional i-vector-based system.
Vulkan-Sim: A GPU Architecture Simulator for Ray Tracing (2022)

This artifact includes sciprts to run the benchmarks and plot the results of vulkan-sim paper published in MICRO 2022 conference. A docker containing Vulkan-Sim and all workload traces used in the paper. Ray tracing can generate photorealistic images with more convincing visual effects compared to rasterization. Recent hardware advances have pushed for the technique to be applied in real-time. Current consumer GPUs feature a dedicated ray tracing acceleration unit, and video game developers have started to make use of ray tracing APIs to bring more realistic graphics to their players. Vulkan features an open-standard API for ray tracing with cross-platform access to modern GPUs. Industry leaders have cooperatively contributed to Vulkan, setting the standard for real-time ray tracing. In this paper, we introduce Vulkan-Sim, a detailed cycle-level simulator for studying Vulkan ray tracing workloads. We build upon the existing GPGPU-Sim simulator, integrating it with Mesa, an open source graphics driver, and add dedicated ray traversal and intersection units. We evaluate several ray tracing workloads with Vulkan-Sim, identifying bottlenecks and inefficiencies of the ray tracing hardware we model. Based on these findings, we also explore a technique of coalescing function calls and independent thread scheduling to alleviate warp divergence and low SIMD efficiency.

Association of novel polymorphisms with the expression of <i>SPARC</i> in normal fibroblasts and with susceptibility to scleroderma (2002)

This study is the first to show that polymorphisms of the SPARC gene are associated with susceptibility to, and clinical manifestations of, SSc and that they may also be functionally important in influencing SPARC expression in skin fibroblasts.
Activated <i>ras</i> Prevents Downregulation of Bcl-XL Triggered by Detachment from the Extracellular Matrix (2000)

Detachment of epithelial cells from the extracellular matrix (ECM) results in a form of apoptosis often referred to as anoikis. Transformation of intestinal epithelial cells by oncogenic ras leads to resistance to anoikis, and this resistance is required for the full manifestation of the malignant phenotype. Previously, we demonstrated that ras-induced inhibition of anoikis in intestinal epithelial cells results, in part, from the ras-induced constitutive downregulation of Bak, a pro-apoptotic member of the Bcl-2 family. Since exogenous Bak could only partially restore susceptibility to anoikis in the ras-transformed cells, the existence of at least another component of the apoptotic machinery mediating the effect of activated ras on anoikis was suggested. Indeed, here we show that, in nonmalignant rat and human intestinal epithelial cells, detachment from the ECM or disruption of the cytoskeleton results in a significant downregulation of the antiapoptotic effector Bcl-X(L), and that activated H- or K-ras oncogenes completely abrogate this downregulation. In addition, we found that enforced downregulation of Bcl-X(L) in the ras-transformed cells promotes anoikis and significantly inhibits tumorigenicity, indicating that disruption of the adhesion-dependent regulation of Bcl-X(L) is an essential part of the molecular changes associated with transformation by ras. While the ras-induced downregulation of Bak could be reversed by pharmacological inhibition of phosphatidylinositol 3 kinase (PI 3-kinase), the effect of ras on Bcl-X(L) was PI 3-kinase- and mitogen-activated protein kinase (MAP kinase)-independent. We conclude that ras-induced resistance to anoikis in intestinal epithelial cells is mediated by at least two distinct mechanisms: one that triggers downregulation of Bak and another that stabilizes Bcl-X(L) expression in the absence of the ECM.

Construction of plants resistant to TYLCV by using artificial zinc-finger proteins (2009)

Previously, we have demonstrated that plant DNA virus replication could be inhibited in Arabidopsis thaliana by using an artificial zinc-finger protein (AZP) and created AZP-based transgenic A. thaliana resistant to DNA virus infection. Here we apply the AZP technology to tomato yellow leaf curl virus (TYLCV) causing serious damage to an important agricultural crop, tomato. An AZP was designed to block binding of the TYLCV replication protein (Rep) to the replication origin. The designed AZP had much higher affinities towards the replication origin than did the Rep, and efficiently blocked Rep binding in vitro. The AZP gene was then introduced into a plant genome with the help of Agrobacterium tumefaciens to generate the transgenic plants. The current status of the construction of the AZP-expressing transgenic plants will be reported.
Structures and Local Polarized Domains of Ferroelectric Organic Films Studied by Atomic Force Microscopy (1998)

We have investigated the surface structures and the local polarized domains of the copolymer thin films of vinylidene fluoride and trifluoroethylene (P(VDF/TrFE)) by atomic force microscopy (AFM). AFM observation revealed that the films consisted of “rod-like” grains and that the surface morphology depended strongly on the annealing condition. We also observed that pairs of “rod-like” grains were gradually formed depending on the length of the annealing time. The local polarized domains were fabricated by applying a high electric field to the film with a conducting AFM tip. The piezoelectric response of the film was detected using the tip with an oscillating electric field and imaged with the topographic images taken simultaneously. The X-ray profile suggested that the thin films had a β-type crystalline structure.
Study for fusion of different sources to determine relevance (2003)

The relevance of a Web document could be measured not only by its text content, but also by some other factors such as the link connectivity and usage patterns. In previous data fusion researches, the text is the only source to determine the relevance, and only the different runs (e.g. by different retrieval models, different query or document representations) on this same source are combined. It is the purpose of this paper to investigate whether the different sources can be combined to determine the relevance with a better accuracy than any single source. We conducted a preliminary experiment to test its feasibility and effectiveness and a positive result was obtained.
Multi-modal Spatial Object Localization in Virtual Reality for Deaf and Hard-of-Hearing People (2021)

Information visualization techniques play an important role in Virtual Reality (VR) because they improve task performance, support cognitive processes, and eventually increase the feeling of immersion. Deaf and Hard-of-Hearing (DHH) persons have special needs for information presentation because they feel and perceive VR environments differently. Therefore, it is necessary to pay attention to requirements about presenting information in VR for this group of users. Previous research showed that adding special features and using haptic methods helps DHH persons to do VR tasks better. In this paper, we propose a novel Omni-directional particle visualization method and also evaluate multi-modal presentation methods in VR for DHH persons, such as audio, visual, haptic, and a combination of them (AVH). Additionally, we compare the results with the results of persons without hearing problems. The methods for information presentation in our study focus on spatial object localization in VR. Our user studies show that both DHH persons and persons without hearing problems were able to do VR tasks significantly faster using AVH. Also, we found out that DHH persons can do visual-related VR tasks faster than persons without hearing problems by using our new proposed visualization method. Our results suggest that the benefits of using audio among persons without hearing problems and the benefits of using vision among DHH persons cause an interesting balance in the results of AVH between both groups. Finally, our qualitative and quantitative evaluation indicates that both groups of participants preferred and enjoyed AVH modality more than other modalities.

Long-term follow-up study in breast cancer patients using serum tumor markers CEA and CA 15-3. (2000)

The aim of this study was to evaluate CEA and CA 15-3 changes in patients surgically treated for breast cancer. One hundred and three women (median age 59 years, range 31-83 years) with pT1-2, pN0-1, M0 breast cancer were followed up for at least 5 years. CEA and CA 15-3 serum levels were measured before operation and every 6 months during follow-up. The diagnostic sensitivity of CEA and CA 15-3 was 22.3% and 33.3% respectively. There was a significant difference (p < 0.01) between pre- and post-operative (6 months and 5 years after surgery) mean CEA serum levels independent of TNM staging. During follow-up, 21 (20.4%) patients showed recurrence of cancer and overall CEA and CA 15-3 sensitivity was 38.1% and 61.1%, with 98.8% and 91.2% specificity, respectively. Tumor marker measurement may be useful in post-surgical follow-up, but at present they are neither sensitive nor specific enough for early diagnosis of malignancy.
Inactivation of Purified Human Recombinant Monoamine Oxidases A and B by Rasagiline and Its Analogues (2004)

The inactivation of purified human recombinant monoamine oxidases (MAO) A and B by rasagiline [N-propargyl-1(R)-aminoindan] and four of its analogues [N-propargyl-1(S)-aminoindan (S-PAI), 6-hydroxy-N-propargyl-1(R)-aminoindan (R-HPAI), N-methyl-N-propargyl-1(R)-aminoindan (R-MPAI), and 6-(N-methyl-N-ethyl carbamoyloxy)-N-propargyl-1(R)-aminoindan (R-CPAI)] has been investigated. All compounds tested, with the exception of R-CPAI, form stoichiometric N(5) flavocyanine adducts with the FAD moiety of either enzyme. No H(2)O(2) is produced during either MAO A or MAO B inactivation, which demonstrates that covalent addition occurs in a single turnover. Rasagiline has the highest specificity for MAO B, as demonstrated by a 100-fold higher inhibition potency (k(inact)/K(i)) compared to MAO A, with the remaining compounds exhibiting lower isozyme specificities. MAO B and MAO A are more selective for the R-enantiomer (rasagiline) compared to the S-enantiomer (S-PAI) by 2500-fold and 17-fold, respectively. Differences in UV/vis and CD spectral data of the complexes of the studied compounds with both MAO A and MAO B are interpreted in light of crystallographic data of complexes of MAO B with rasagiline and its analogues (Binda, C.; et al. J. Med. Chem. 2004, 47, 1767-1774.

Learning HIP dynamics with neural networks (1991)

The authors investigate backpropagation neural networks for learning the dynamics of densification during hot isostatic pressing (HIP). The micromechanical description of the dynamics is extraordinarily messy, contains over 27 hard-to-measure parameters, and required 10+ years to develop. Thus, supervised learning is quite an attractive alternative. The authors' results indicate that it is a feasible alternative. It only took a few hours of training, with one set of data, and very little prior information about the process for a backpropagation neural network to acceptably learn HIP densification dynamics.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
