ProTracer: Towards Practical Provenance Tracing by Alternating Between Logging and Tainting (2016)

Provenance tracing is a very important approach to Advanced Persistent Threat (APT) attack detection and investigation. Existing techniques either suffer from the dependence explosion problem or have non-trivial space and runtime overhead, which hinder their application in practice. We propose ProTracer, a lightweight provenance tracing system that alternates between system event logging and unit level taint propagation. The technique is built on an on-the-fly system event processing infrastructure that features a very lightweight kernel module and a sophisticated user space daemon that performs concurrent and out-of-order event processing. The evaluation with different realistic system workloads and a number of attack cases show that ProTracer only produces 13MB log data per day, and 0.84GB(Server)/2.32GB(Client) in 3 months without losing any important information. The space consumption is only < 1.28% of the state-of-the-art, 7 times smaller than an off-line garbage collection technique. The run-time overhead averages <7% for servers and <5% for regular applications. The generated attack causal graphs are a few times smaller than those by existing techniques while they are equally informative.
A home network controller for providing broadband access to residential subscribers (1995)

As new broadband networks and multimedia services emerge, users are increasingly likely to access information remotely from their homes. The authors present a cost-effective method for connecting multimedia terminals in a residence to the external broadband network, so as to support multiple simultaneous user sessions. At the heart of the proposed design is a home network controller that terminates the external broadband network upon its entry into a home, and enables media distribution within the home by employing existing networking technologies, such as coaxial cable for real-time multimedia delivery to television sets, and Ethernet for data communication to home computers.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Range-based bitmap indexing for high cardinality attributes with skew (2002)

Bitmap indexing, though effective for low cardinality attributes, can be rather costly in storage overhead for high cardinality attributes. Range-based bitmap (RBM) indexing can be used to reduce this storage overhead. The attribute values are partitioned into ranges and a bitmap vector is used to represent a range. With RBM, however, the number of records assigned to different ranges can be highly uneven, resulting in non-uniform search times for different queries. We present and evaluate a dynamic bucket expansion and contraction (DBEC) approach to simultaneously constructing range-based bitmap indexes for multiple high-cardinality attributes. Simulations are conducted to evaluate this DBEC approach. Both synthetic and real data are used in the simulations. The results show that (1) with highly skewed data, DBEC performs quite well compared with a simple approach and (2) DBEC compares favorably with the optimal approach.

Abstract The condensation of various halomethyl heterocycles with the potassium salt of the alanine derivative 3, followed by hydrolysis, gave a series of novel 3‐heterocyclic‐2‐methylalanines.
A new route for the synthesis of SiC–MoSi<sub>2</sub>ceramic composite materials (1996)

SiC–MoSi2 ceramic composite materials with controlled molybdenum content can be prepared by reaction of silicon with previously formed molybdenum carbide.
Optical fiber probe monitor for neonatal bilirubinemia (2003)

Computer simulations of light propagation in a multilayered skin model (Monte Carlo) and experimental measurements with scaled phantom models of layered skin are reported. The goal is an algorithm for reliable quantification bilirubin despite variations in skin optics, using spectra from an optical fiber probe taped onto the skin. In the model the level of pigmentation in each of the four principle layers of the skin, the pigmented epidermis, the superficial papillary dermis, the venous plexus, and the reticular dermis, is varied by varying absorption coefficient. The Monte Carlo simulation gives the reflectance value for the skin and a map of the light distribution within the skin.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Quantifying colour appearance. part V. simultaneous contrast (1995)

Abstract Experiments were carried out to investigate the effect of simultaneous contrast on colour appearance by varying the lightness, colourfulness, and hue of an induction field surrounding a test colour. A total of 814 test/surround combinations were displayed on high‐resolution colour displays. Each was assessed by a panel of five to six observers using a magnitude estimation technique. the results indicate that colours presented on a computer display are affected by simultaneous contrast in a similar way to surface colours. All three colour appearance parameters studied (i.e., lightness, colourfulness, and hue) are affected and these effects are summarized. In general, the results support and add to the findings of the other studies. the Hunt colour appearance model was tested and gave a somewhat poor prediction to this data set. Further modifications are required to improve its performance. © 1995 John Wiley & Sons, Inc.
Using Agricultural Education As The Context To Teach Life Skills (2001)

Over the years agricultural education has not done an adequate job of effectively defining or describing its meaning and purpose. As with the broad agricultural industry, the view of agricultural education varies between and among groups, within and outside of the profession, and has evolved according to global, regional, and local pressures including those originating from political, societal, and technological changes (National Research Council, 1988). This qualitative study investigated the perceptions held by individuals involved in agricultural education or the broadly defined agricultural industry as to how agricultural education can be promoted as a viable alternative for the instruction of academic and workplace skills, reducing some of the image problems associated with vocational education. Results indicate that participants believe agricultural education should remain a community-based program, and should incorporate more science-based instruction, but there is much confusion as to how traditional program goals such as FFA and SAE can be met with these changes. The conclusions and recommendations focus on a set of questions developed to guide future research on these issues.
High-Throughput Synthesis of <i>N</i>3-Acylated Dihydropyrimidines Combining Microwave-Assisted Synthesis and Scavenging Techniques (2003)

[reaction: see text] The solution-phase synthesis of N3-acylated dihydropyrimidines was achieved utilizing microwave flash heating both in the synthesis (acylation) and purification (scavenging) steps. Quenching times for excess anhydrides using polystyrene or silica-supported diamine sequestration reagents were reduced from several hours to minutes utilizing microwave irradiation. The use of water as sequestration agent, coupled with an efficient solid-phase extraction workup technique allowed the rapid generation of a 20-member library of N3-acylated dihydropyrimidines.

In this study, we investigated the mechanism responsible for anti-cancer and radiosensitizing effects of lanatoside C in colorectal cancer cells. Lanatoside C-treated cells showed classic patterns of autophagy, which may have been caused by lanatoside C-induced mitochondrial aggregation or degeneration. This mitochondrial dysfunction was due to disruption of K + homeostasis, possibly through inhibition of Na + /K + -ATPase activity. In addition, lanatoside C sensitized HCT116 cells (but not HT-29 cells) to radiation in vitro . γ-H2AX, a representative marker of DNA damage, were sustained longer after combination of irradiation with lanatoside C, suggesting lanatoside C impaired DNA damage repair processes. Recruitment of 53BP1 to damaged DNA, a critical initiation step for DNA damage repair signaling, was significantly suppressed in lanatoside C-treated HCT116 cells. This may have been due to defects in the RNF8- and RNF168-dependent degradation of KDM4A/JMJD2A that increases 53BP1 recruitment to DNA damage sites. Although lanatoside C alone reduced tumor growth in the mouse xenograft tumor model, combination of lanatoside C and radiation inhibited tumor growth more than single treatments. Thus, lanatoside C could be a potential molecule for anti-cancer drugs and radiosensitizing agents.
Intestinal cholesterol absorption (1999)

The strong association between intestinal cholesterol absorption and total plasma cholesterol level has renewed interest in the absorptive process and stimulated the generation of new animal models. Increasingly, new studies suggest that cholesterol absorption is genetically controlled and supports a protein-mediated mechanism for cholesterol uptake into the intestinal mucosal cell. Insights into potential mechanisms are predicted to lead to novel pharmacological approaches to inhibit cholesterol absorption.
Evidence of scattering anisotropy effects on boundary conditions of the diffusion equation (2000)

We present experimental evidence that the diffusion process close to the boundary is fundamentally different from the bulk diffusion in the sense that it is affected by the scattering properties of the individual centers. Systematic measurements show a nontrivial behavior of the extrapolation length ratio on the scattering anisotropy of individual particles. The results are compared with other works and are supported by an independent Monte Carlo simulation. A simple analytical model that emphasizes the influence of the last scattering event successfully describes the results.
Noise2Filter: fast, self-supervised learning and real-time reconstruction for 3D computed tomography (2020)

Abstract At x-ray beamlines of synchrotron light sources, the achievable time-resolution for 3D tomographic imaging of the interior of an object has been reduced to a fraction of a second, enabling rapidly changing structures to be examined. The associated data acquisition rates require sizable computational resources for reconstruction. Therefore, full 3D reconstruction of the object is usually performed after the scan has completed. Quasi-3D reconstruction—where several interactive 2D slices are computed instead of a 3D volume—has been shown to be significantly more efficient, and can enable the real-time reconstruction and visualization of the interior. However, quasi-3D reconstruction relies on filtered backprojection type algorithms, which are typically sensitive to measurement noise. To overcome this issue, we propose Noise2Filter, a learned filter method that can be trained using only the measured data, and does not require any additional training data. This method combines quasi-3D reconstruction, learned filters, and self-supervised learning to derive a tomographic reconstruction method that can be trained in under a minute and evaluated in real-time. We show limited loss of accuracy compared to training with additional training data, and improved accuracy compared to standard filter-based methods.
Body effects in tri-gate bulk FinFETs for DTMOS (2006)

Body factor was investigated in tri-gate bulk FinFET for the first time. Increment of on-state current and decrement of off-state current are achieved by body bias modulation. Electrical measurements were carried out to investigate the body effects in view points of a fin width that governs short-channel effects. A wide fin width was preferable for a dynamic threshold voltage operation and wide range of the threshold adjustment, however, the fin width is limited for suppression of short-channel effects. This work can provide feasibility of DTMOS application of FinFETs for low-power and high-performance application.

Silicon 45° micromirrors fabricated by etching in alkaline solutions with organic additives (2013)

The fabrication of 45° micromirrors by silicon anisotropic etching in potassium hydroxide (KOH) and tetramethylammonium hydroxide (TMAH) solutions containing organic additives is investigated in this paper. The reflective planes are formed by {110} sidewall planes inclined at 45° towards the Si (100) wafer. Isopropyl alcohol and Triton X-100 surfactant are used as additives, because they are supposed to provide the etch rate ratio R(100)/R(110) > 1, which is necessary for {110} sidewalls development. The fabricated spatial microstructures with 45° sidewalls are examined in terms of the {110} surface roughness and the quality of the {110} sidewall profile. The KOH solution saturated with the alcohol gives the striped {110} surface, though the stripes almost disappear after addition of Triton surfactant to KOH and TMAH etchants. The 45° sidewall profiles fully defined by {110} planes are obtained in KOH as well as TMAH solutions containing additives. The measurements of micromirrors’ reflectivity indicate that replacement of the alcohol by Triton surfactant in the KOH solution reduces the optical power loss caused by the reflection. The achieved reflectivity is comparable with the one obtained by etching in the TMAH solution with surfactant.

Direct fitting of center collinear circles for equidistant fish-eye camera calibration (2013)

An equidistant fish-eye camera can be calibrated using a single image of two sets of parallel lines in the scene, which is very convenient for practical applications. The core of the calibration procedure is the fitting of center collinear circles that intersect at two vanishing points. A fast and accurate fitting method that can be used for equidistant fish-eye camera calibration is presented. First, the fitting problem is formulated as a nonlinear least square problem and solved using Levenberg-Marquardt optimization. The objective function is also derived, as well as the Jacobian required by the Levenberg-Marquardt algorithm. It is also demonstrated how to determine the initial estimations. Experimental results on synthetic data have demonstrated the superiority of our method to two existing approaches in terms of speed and accuracy. Results on real data have also demonstrated its effectiveness for fish-eye camera calibration.
Damping torsional oscillations due to network faults using the dynamic flywheel damper (1997)

The technical feasibility of using a dynamic flywheel damper to damp shaft torsional oscillations in large turbine generators is investigated. Torsional damping is achieved using the slide friction force of the flywheel damper based on generator speed. A system is defined and the shaft torques following various electrical system disturbances are evaluated and analysed. It is shown that substantial damping can be implemented with a well designed flywheel damper, thus reducing the risk of significant shaft damage due to network disturbances. The equivalent models and designs for the flywheel dampers fitted into the shaft couplings of turbine mechanical systems are also described. This method can effectively damp the torsional oscillations due to the high reliability of the damper.
The effect of the digestion products of lactose (glucose and galactose) on its intraintestinal, in vivo hydrolysis by exogenous microbial beta-D-galactosidase. (1986)

Exogenous, microbial beta-D-galactosidases are capable of effecting hydrolysis of lactose in situ in the gastrointestinal tract of lactase-deficient subjects when given as replacement therapy at mealtime. As its digestion products-glucose and galactose-are known to inhibit lactose hydrolysis in vitro, the effect of adding excess monosaccharide to milk on the hydrolytic efficiency of a beta-galactosidase from Aspergillus niger in adult lactose-malabsorbers was tested. Subjects were studied with 360-ml volumes of milk containing 18 g of carbohydrate. This was administered as intact milk, as lactose-prehydrolyzed milk, and as milk to which 399 mg of Lactase N was added within 5 minutes of consumption. This latter Lactase N-treated milk was administered alone and with graded levels of glucose-9, 18, and 36 g-and with similar doses of galactose. The Lactase N enzyme alone at mealtime reduced breath H2 production by 68% as compared to intact milk. The addition of monosaccharides produced no change in the apparent hydrolytic efficiency of the Lactase N in situ. Thus, product inhibition is unlikely to be the basis for the limited efficiency of intraintestinal hydrolysis of milk lactose by the enzyme from A niger.
Context-Aware Recruitment Scheme for Opportunistic Mobile Crowdsensing (2015)

The ubiquity of mobile devices coupled with the advances in Internet of Things (IoT) technologies has led to the development of large-scale applications that can collect information about people and their environments in real-time. Such applications are referred to as Mobile Crowdsensing (MCS). In MCS, tasks are allocated to participants (mobile devices) by a remote server according to the application requirements. The key challenge is reducing the energy consumption of the participating mobile devices. One of the effective approaches to reduce energy consumption of MCS applications is to improve efficiency of task allocation. An efficient task allocation approach can optimize several aspects of MCS applications such as task coverage (minimum number of participants required for a MCS task), data quality, and sensing costs. In this paper, we propose a novel Context-Aware Task Allocation (CATA) approach that aims to allocate sensing tasks to the best participant set while improving energy efficiency in MCS applications. Another important feature of the proposed CATA approach is that it preserves the privacy of participants' by only disclosing the less sensitive data to the server. The proposed approach employs local and global task allocation methods to enable two levels of data sharing and privacy. We describe the series of experiments that were conducted to validate our proposed approach in terms of coverage and efficiency.
High soft-error tolerance body-tied SOI technology with partial trench isolation (PTI) for next generation devices (2003)

It was proven that the body-tied SOI technology with partial trench isolation (PTI) has significant high soft-error immunity. As compared with the bulk, a three-order reduction of the soft-error rate for a 0.18 /spl mu/m SOI 4 Mbit SRAM with the PTI was successfully realized by the balanced combination of the SOI thickness and well resistance. It is estimated that the soft-error immunity for the floating-body device degrades because large charge collection is induced by not only the body strike but also the drain strike. A design guideline of the SOI structure to suppress soft errors is presented. According to the guideline, beyond 0.13 /spl mu/m node, high soft-error immunity for the body-tied SOI device was projected as compared with the bulk as well as the body-floating SOI device.
An Organic Down‐Converting Material for White‐Light Emission from Hybrid LEDs (2014)

A novel BODIPY-containing organic small molecule is synthesized and employed as a down-converting layer on a commercial blue light-emitting diode (LED). The resulting hybrid device demonstrates white-light emission under low-current operation, with color coordinates of (0.34, 0.31) and an efficacy of 13.6 lm/W; four times greater than the parent blue LED.
Repeated treatment with high dose cyclophosphamide for severe autoimmune diseases. (2013)

High dose cyclophosphamide (HiCY) without stem cell rescue has been shown to induce remissions in patients with severe autoimmune disorders (SADS). However, up to 80% of these patients ultimately relapse. Here we review the outcomes of seven patients treated with two cycles and one patient treated with three cycles of HiCY. The diseases re-treated were scleroderma, multiple sclerosis, three patients with severe aplastic anemia (SAA), and three patients with myasthenia gravis (MG). All but two patients with SAA had received standard immunomodulatory therapy for their disease up front and had been refractory. All patients had complete hematologic recovery. Overall survival in this cohort was 100%. All patients relapsed after the initial cycle but event free survival thereafter was 93.3%. All are still in remission except two MG patients, one of whom relapsed after a severe GI infection requiring hospitalization, and the other relapsed 3 years after the second treatment and she did not respond to the third treatment. This shows that HiCY can be safely re-administered in patients with SAA and refractory SADS. The quality and duration of second remissions appears to be equal or superior to the first remission.
