Learning to rank for test case prioritization (2022)

In Continuous Integration (CI) environments, the productivity of software engineers depends strongly on the ability to reduce the round-trip time between code commits and feedback on failed test cases. Test case prioritization is popularly used as an optimization mechanism for ranking tests by their likelihood in revealing failures. However, existing techniques are usually time and resource intensive making them not suitable to be applied within CI cycles. This paper formulates the test case prioritization problem as an online learn-to-rank model using reinforcement learning techniques. Our approach minimizes the testing overhead and continuously adapts to the changing environment as new code and new test cases are added in each CI cycle. We validated our approach on an industrial case study showing that over 95% of the test failures are still reported back to the software engineers while only 40% of the total available test cases are being executed.
Selective adsorption/desorption of nucleic acids on submicron‐sized polymeric particles (1989)

DNA can be removed or separated by the selective adsorption/desorption on positively charged submicronsized polymeric particles (SSPP). The selective adsorption of DNA, in the presence of protein, on positively charged SSPP was accomplished by increasing the concentration of potassium phosphate or sodium phosphate. The adsorption of DNA was not affected by the concentration of potassium phosphate or sodium phosphate up to 1.2M. On the other hand, the adsoprtion of a protein (bovine serum albumin) was completely impeded by 170mM potassium phosphate. DNA adsorbed on SSPP could be desorbed by increasing the concentration of NaCl or KCl, thus it can be recovered. DNA desorbed from SSPP when the concentration of NaCl or KC was higher than 0.6M. A complete desorption of DNA was achieved at the concentration of NaCl or KCl above 1.2M.
Attention-Guide Walk Model in Heterogeneous Information Network for Multi-Style Recommendation Explanation (2020)

Explainable Recommendation aims at not only providing the recommended items to users, but also making users aware why these items are recommended. Too many interactive factors between users and items can be used to interpret the recommendation in a heterogeneous information network. However, these interactive factors are usually massive, implicit and noisy. The existing recommendation explanation approaches only consider the single explanation style, such as aspect-level or review-level. To address these issues, we propose a framework (MSRE) of generating the multi-style recommendation explanation with the attention-guide walk model on affiliation relations and interaction relations in the heterogeneous information network. Inspired by the attention mechanism, we determine the important contexts for recommendation explanation and learn joint representation of multi-style user-item interactions for enhancing recommendation performance. Constructing extensive experiments on three real-world datasets verifies the effectiveness of our framework on both recommendation performance and recommendation explanation.

A system of electric remote-control accounting (1938)

THE ACCOUNTING system which will be outlined in this paper will be discussed mainly in its application to a department store. However, it will not require any great stretch of the imagination to visualize the application of the same system and devices to other fields, including factory production control and pay rolls, public-utility accounts receivable, and others.
1A2-A21 Development of Street Tree Climbing Robot for Pruning Branches WOODY-2 : Implementation of and Experiment on Adjust Function of Grasping Power (2010)

We are developing a street tree climbing robot which works at height instead of man. In this paper, we describe Controlling Assistant Technique with measuring the grasping power. It was difficult to make adjustment to grasping power. To simplify the operation, we installed a strain gage on each gripper to measure the grasping power. We constructed and estimated the system which limits the grasping power automatically.
QZSS RTK-PPP Application to Autonomous Cars (2016)

This paper presents a total view of Real-Time Kinematic Precise Point Positioning (RTK-PPP) using the L6 augmentation signal of Japanese Quasi-Zenith Satellite System (QZSS), and introduce its application to autonomous cars as a snowplow example with experimental results. RTK-PPP is one of the today’s most accurate real-time positioning methods. RTK-PPP realizes not only centimeter-level accuracy, but also the first fix within one minute, with integrity information of its user range accuracies. Japanese QZSS has been realizing RTK-PPP service for QZSS Application Demonstration since December 2010 using Centimeter-class Augmentation System (CMAS), which is developed by SPAC. A hundred companies have joined this demonstration until today. Besides, QZSS will commence the practical service named Centimeter Level Augmentation Service (CLAS) since spring 2018 with 4-satellite constellation. Furthermore, QZSS plans 7-satellite constellation in 2023. RTK-PPP fits autonomous cars. It can be said to be a powerful method for autonomous car application.
Numerical Model for the Drag Force Method to Evaluate Hysteresis Loss (2008)

To determine the hysteresis loss in a sample, usually the enclosed area of the loop is evaluated. In the drag force method, based on a proper energy balance, the hysteresis loss is obtained by analyzing the drag force profile when slowly moving the sample forward and backward through the strong field of permanent magnets. The aim of the method is not to be an alternative to conventional measurements, but rather to use it for nondestructive evaluation. A numerical time-stepping model is presented that calculates the drag force profile. At every time step, the sample is slightly moved relative to the magnet. The model is based on 2-D-FE computations including magnetic hysteretic material behavior using the Preisach model. The drag force is obtained by using the Maxwell stress tensor. The numerical model is validated by measurements and by comparing the ldquodrag forcerdquo hysteresis losses with the hysteresis losses computed conventionally by the integral of . Several simulations were carried out to investigate the influence of parameters such as the number of permanent magnets, the distance between the magnets and the sample, and the presence of defects in the sample.
Study on Maize Leaf Morphological Modeling and Mesh Simplification of Surface (2008)

According to the need of canopy visualization calculation in the digital plant research, we introduced a method, using Non-Uniform Rational B-Splines (NURBS) interpolation and multi-line segment splitting algorithm, to reconstruct the 3D morphological structure of maize leaf with a complexity controllable mesh. Using the data cloud obtained by digitizer, construct the surface of maize leaf by calculating the knot vectors and reverse calculating surface control points by difference calculation. The final visualization effect is realistic. According to leaf morphological characteristics, leaf surface mesh can be simplified by using inverse calculation of multi-line segment splitting algorithm, and the surface main characteristics can be maintained simultaneously. This method can be used in canopy visualization calculation and light distribution calculation. Results showed that it can improve the calculation efficiency obviously without increase the calculation error.
All-Solid Perovskite Solar Cells with HOCO-R-NH3+I– Anchor-Group Inserted between Porous Titania and Perovskite (2014)

HOCO-R-NH3+I monolayer working as an anchor for perovskite (CH3NH3PbI3 (abbreviation: PEROVI3)) was inserted between the surface of porous metal oxide (titania or alumina) and the PEROVI3. Power conversion efficiency (PCE) of PEROVI3 solar cells increased from 8% to 10% after the HOCO-R-NH3+I– monolayer was inserted. Moreover, PCE of 12% was achieved for cells fabricated at optimized conditions. This increase in the efficiency was explained by retardation of charge recombination, and better PEROVI3 crystal growth, which improves PEROVI3 network on these porous metal oxides. It was proved that PEROVI3 crystal growth can be controlled by HOCO-R-NH3+I– on these porous metal oxides.

Studying ancient crop provenance: implications from δ 13 C and δ 15 N values of charred barley in a Middle Bronze Age silo at Ebla(NW Syria) (2012)

The discovery of a storeroom full of barley and other cereals (L.9512) in the proto-historic site of Ebla has provided a unique opportunity to study the centralized storage system of the early city-state from a different perspective. Epigraphic evidence available within the site reveals a complex system of taxation which included gathering grain tributes from satellite sites and redistributing semi-finished products such as flour. In this paper, we intend to explore the possibilities of a combined approach to studying the storage system, based on estimated barley grain volumes and δ(13)C-δ(15)N analyses. This approach is used to distinguish between grain from different harvesting sites and to identify any grain cultivated using special agricultural practices (e.g. manuring or irrigation). The basic assumption for this kind of analysis is that the growth-site conditions, natural or anthropogenic, of harvested cereals are reflected in their grain size and δ(13)C-δ(15)N values. Since the remains found in the storeroom were charred, the first task was to evaluate the effect of carbonization on the δ(13)C-δ(15)N and the size of the grains. Thus, the effect of charring was tested on modern samples of Syrian barley landraces. Once it had been ascertained that fresh grains reduced to charred remains retain their original biometric and isotopic traits, the ancient material was examined. Thirteen groups were identified, each characterized by a specific average volume and specific carbon and nitrogen values. The analysis revealed that what had first appeared to be a homogeneous concentration of grain was in fact an assemblage of barley harvested from different sites.
Increased Proportion of Variance Explained and Prediction Accuracy of Survival of Breast Cancer Patients with Use of Whole-Genome Multiomic Profiles (2016)

Whole-genome multiomic profiles hold valuable information for the analysis and prediction of disease risk and progression. However, integrating high-dimensional multilayer omic data into risk-assessment models is statistically and computationally challenging. We describe a statistical framework, the Bayesian generalized additive model ((BGAM), and present software for integrating multilayer high-dimensional inputs into risk-assessment models. We used BGAM and data from The Cancer Genome Atlas for the analysis and prediction of survival after diagnosis of breast cancer. We developed a sequence of studies to (1) compare predictions based on single omics with those based on clinical covariates commonly used for the assessment of breast cancer patients (COV), (2) evaluate the benefits of combining COV and omics, (3) compare models based on (a) COV and gene expression profiles from oncogenes with (b) COV and whole-genome gene expression (WGGE) profiles, and (4) evaluate the impacts of combining multiple omics and their interactions. We report that (1) WGGE profiles and whole-genome methylation (METH) profiles offer more predictive power than any of the COV commonly used in clinical practice (e.g., subtype and stage), (2) adding WGGE or METH profiles to COV increases prediction accuracy, (3) the predictive power of WGGE profiles is considerably higher than that based on expression from large-effect oncogenes, and (4) the gain in prediction accuracy when combining multiple omics is consistent. Our results show the feasibility of omic integration and highlight the importance of WGGE and METH profiles in breast cancer, achieving gains of up to 7 points area under the curve (AUC) over the COV in some cases.

Steady-state diffusion-controlled A+A→0 reaction in Euclidean and fractal dimensions: Rate laws and particle self-ordering (1989)

For diffusion-limited reactions of the type A+A\ensuremath{\rightarrow}0, we present a theory for the pair correlation function and the macroscopic reaction law for the Euclidean dimensions d=1, 2, 3 and for self-similar fractal structures with spectral dimension such that 1\ensuremath{\le}${d}_{s}$\ensuremath{\le}2. In any dimension we define a length \ensuremath{\Lambda}, which is the typical size of the depletion zone around each particle. \ensuremath{\Lambda} is expressed as a function of a fundamental size \ensuremath{\xi}= \ensuremath{\surd}\ensuremath{\rho}D/R , where \ensuremath{\rho} is the steady-state density, R the external source rate, and D the microscopic diffusion constant. For ${d}_{s}$\ensuremath{\le}2, we obtain the ``fractal'' reaction order X=1+2/${d}_{s}$ and a mesoscopic, density-dependent depletion zone around each particle. We give an interpretation of the particle self-ordering and anomalous rate laws in terms of the random-walk topological properties.

Decreased lumen size after balloon injury despite inhibition of neointimal thickening and antivasospastic treatment (1994)

Since calcium antagonist treatment was not able to influence the reduction of lumen size, it is unlikely that the narrowing is due to reversible spasm of the carotid artery in the first two weeks after inducing a balloon lesion. Alternatively, chronic vasospasm of neointimal smooth muscle might not be very sensitive to calcium antagonists.
Investigating the relationships between dialog patterns and user satisfaction in customer service chat systems based on chat log analysis (2022)

While previous studies of customer service chat systems (CSCS) understood user satisfaction as individuals’ subjective perceptions and depended heavily on self-report methods for satisfaction measurement, this article presents an obtrusive chat log analysis that followed the established approaches of search log analysis and examined the relationships between dialog patterns and user satisfaction. An 81-day chat log was obtained from a real-world CSCS that involves both a chatbot and human representatives. A total of 75,918 chat sessions/147,972 sub-sessions containing 251,556 user messages and 349,416 system messages were extracted after data processing and analysed in terms of topic, length and path. As found in this study, the users were more likely to get satisfied on low-difficulty topics. The dialog between the CSCS and users was shallow in general. While human representatives’ elaboration contributed to user satisfaction, the chatbot was responsible for damaging user satisfaction. The significance of this study consists not only in providing objective evidence about user satisfaction in online chat but also in generating practical implications for the CSCS to improve user satisfaction.
Collembola are Unlikely to Cause Human Dermatitis (2009)

Abstract There have been several unconfirmed case reports of dermatitis caused by Collembola (springtails). We recently investigated two nurses with dermatitis suspected to be caused by Drepanura Schött (Collembola: Entomobryidae). IgE antibodies to Collembola proteins were not detected in sera from the nurses and skin tests with the Collembola extract and crushed whole Collembola were negative in both the nurses and volunteers. This study suggests that the springtail Drepanura may not cause human dermatitis and that other organisms and organic matter that are also found in the moist environment inhabited by Collembola might instead be responsible.
Measurement and Analysis of the Naphthalene — Octafluoronaphthalene Phase Diagram: Complex Formation in Solid and Liquid (1999)

Naphthalene–octafluoronaphthalene room pressure solid–liquid phase diagram has been assessed by means of differential scanning calorimetry and powder X-ray diffraction analyses. Thermodynamic properties are analysed through the associated liquid model. The solid states consists of six crystalline phases with well defined composition: one for naphthalene, two for octafluoronaphthalene and three for an equimolecular intermolecular compound. This complex melts congruently at (406.3±0.3) K, i.e., about fifty degrees higher than its components and the resulting liquid is moderately associated. The solid–solid phase transitions of this complex are strongly energetic. The corresponding overall change of entropy stands for two third times the entropy of fusion. The consecutive increasing of crystalline symmetry and positional disorder is clearly visible on diffraction patterns.
Mesenchymal stromal cells orchestrate follicular lymphoma cell niche through the CCL2-dependent recruitment and polarization of monocytes (2012)

Accumulating evidence indicates that infiltrating stromal cells contribute directly and indirectly to tumor growth in a wide range of cancers. In follicular lymphoma (FL), malignant B cells are found admixed with heterogeneous lymphoid-like stromal cells within invaded lymph nodes and BM. In addition, mesenchymal stromal cells (MSCs) support in vitro FL B-cell survival, in particular after their engagement toward lymphoid differentiation. We show here that BM-MSCs obtained from patients with FL (FL-MSCs) display a specific gene expression profile compared with MSCs obtained from healthy age-matched donors (HD-MSCs). This FL-MSC signature is significantly enriched for genes associated with a lymphoid-like commitment. Interestingly, CCL2 could be detected at a high level within the FL-cell niche, is up-regulated in HD-MSCs by coculture with malignant B cells, and is overexpressed by FL-MSCs, in agreement with their capacity to recruit monocytes more efficiently than HD-MSCs. Moreover, FL-MSCs and macrophages cooperate to sustain malignant B-cell growth, whereas FL-MSCs drive monocyte differentiation toward a proangiogenic and lipopolysaccharide-unresponsive phenotype close to that of tumor-associated macrophages. Altogether, these results highlight the complex role of FL stromal cells that promote direct tumor B-cell growth and orchestrate FL-cell niche, thus emerging as a potential therapeutic target in this disease.
Growth and in situ x-ray characterization of YBa2Cu3Ox/LaAlO3 superlattices (1996)

We utilized a miniature sputtering cell with mylar windows and multitarget sputtering guns in order to study the growth of YBCO/LaAlO3 superlattices on SrTiO3 substrates. Computer modeling of the diffraction spectra enabled us to determine the interface width between the layers. After deposition of the superlattices, the substrate temperature was increased to study any interdiffusion.
Unified design algorithm for complex FIR and IIR filters (2002)

A general filter design norm is proposed with the intent of producing a unified design algorithm for all types of filters - FIR, IIR and 2D FIR with complex specifications. The Chebyshev, least squares, and constrained least squares problems become special cases because this norm uses a convex combination of the 2-norm and the Chebyshev norm. The primary benefit of this new problem formulation is that a single efficient multiple exchange algorithm (similar to Remez) has been developed to cover all the different filter types for magnitude and phase approximation. In the new algorithm, a small subproblem is formed at each step and is solved with an iterative reweighted least squares technique which can handle the design of complex filters easily. Finally, the norm definition allows easy trade-offs between the relative importance of error energy and worst-case error.
