CMOS Image Sensor with an Overlaid Organic Photoelectric Conversion Layer: Optical Advantages of Capturing Slanting Rays of Light (2024)

We prepared a trial product of a CMOS image sensor with a thin overlaid panchromatic organic photoelectric conversion layer and evaluated the dependences of its sensitivity and cross-talk upon the angle of incident light. We verified the optical advantages of the proposed sensor, which should enable the reductions in F-number and size of optical lenses.
Evolving computer programs using rapidly reconfigurable field-programmable gate arrays and genetic programming (1998)

This paper describes how the massive parallelism of the rapidly reconfigurable Xilinx XC6216 FPGA (in conjunction with Virtual Computing's H.O.T. Works board) can be exploited to accelerate the time-consuming fitness measurement task of genetic algorithms and genetic programming. This acceleration is accomplished by embodying each individual of the evolving population into hardware in order to perform the fitness measurement task. A 16-step sorting network for seven items was evolved that has two fewer steps than the sorting network described in the 1962 O'Connor and Nelson patent on sorting networks (and the same number of steps as a 7-sorter that was devised by Floyd and Knuth subsequent to the patent and that is now known to be minimal). Other minimal sorters have been evolved.
A Yeast Recombinant Aquaporin Mutant That Is Not Expressed or Mistargeted in Xenopus Oocyte Can Be Functionally Analyzed in Reconstituted Proteoliposomes (1998)

We have recently identified AQPcic (for aquaporin cicadella), an insect aquaporin found in the digestive tract of homopteran insects and involved in the elimination of water ingested in excess with the dietary sap (Le Cahérec, F., Deschamps, S., Delamarche, C., Pellerin, I., Bonnec, G., Guillam, M. T., Gouranton, J., Thomas, D., and Hubert, J. F. (1996) Eur. J. Biochem. 241, 707-715). Like many other aquaporins, AQPcic is inhibited by mercury reagents. In this study, we have demonstrated that residue Cys82 is essential for mercury inhibition. Another mutant version of AQPcic (AQP-C134S), expression of which in Xenopus laevis failed to produce an active molecule, was successfully expressed in Saccharomyces cerevisiae. Using stopped-flow analysis of reconstituted proteoliposomes, we demonstrated that the biological activity and Hg sensitivity of yeast-expressed wild type and mutant type AQPcic was readily assessed. Therefore, we propose that the yeast system is a valid alternative to Xenopus oocytes for studying particular mutants of aquaporin.

Rate-adaptive transmission of H.263 video for multicode DS/CDMA cellular systems in multipath fading (2003)

The variable bit rate nature of compressed video remains a challenge to the transmission of real-time video over mobile CDMA cellular networks. Indeed, H.263 and MPEG-4 video bitstreams are characterized. by high peak rates and frequent rate variations, which are difficult to support in 2.5G and 3G mobile networks. In this paper, we propose a simple scheme which minimizes the peak transmission rate and its variance, which leads to a lower average bit-error rate (BER) and thus a higher received video quality. By introducing a small delay in the decoding process, the video output stream can be buffered at the video decoder end. We propose an algorithm which uses this buffering capability to perform real-time smoothing of the video stream. The transmitter then varies the number of codes assigned to the stream in order to support the remaining smaller rate variations. We simulate an end-to-end video communication system for the IS-95B uplink. It consists of an H.263 codec, an H.223 multiplexer and the physical layer components of the IS-95B standard. The transmitted signal is subject to multipath fading and multiple-access interference, obtained by simulating all the other users in the cell. Our joint smoothing/rate adaptation algorithm leads to a significant gain in the video quality scheme, as compared to previous approaches.
HEVC Inter Coding Using Deep Recurrent Neural Networks and Artificial Reference Pictures (2018)

The efficiency of motion compensated prediction in modern video codecs highly depends on the available reference pictures. Occlusions and non-linear motion pose challenges for the motion compensation and often result in high bit rates for the prediction error. We propose the generation of artificial reference pictures using deep recurrent neural networks. Conceptually, a reference picture at the time instance of the currently coded picture is generated from previously reconstructed conventional reference pictures. Based on these artificial reference pictures, we propose a complete coding pipeline based on HEVC. By using the artificial reference pictures for motion compensated prediction, average BD-rate gains of 1.5% over HEVC are achieved.
[Basic peptides in bee venom, II. Synthesis of two pentapeptides from the sequence of the mast-cell-degrading peptide (author's transl)]. (1976)

The synthesis of two protected pentapeptides is described. The peptides are fragments of the sequence of a mast-cell degranulating peptide from bee venom. The fragments Boc-Lys(Z)-Ile-Cys(SiPr)-Gly-Lys(Z)(I) and Boc-Pro-His(Trt)-Ile-Cys(Trt)-Arg(Tos) (II) were synthesized conventionally. The deprotection of the alpha-amino group by HCl/acetic acid of Boc-Ile-Cys(SiPr)-Gly-Lys(Z) was accompanied by a disulfide exchange at the cysteine residue. After the hydrolysis of fragment II with 6N HCl, allo-isoleucine could be detected by gas chromatography and amino-acid analysis.
Analyzing network traffic to detect self-decrypting exploit code (2007)

Remotely-launched software exploits are a common way for attackers to intrude into vulnerable computer systems. As detection techniques improve, remote exploitation techniques are also evolving. Recent techniques for evasion of exploit detection include polymorphism (code encryption) and meta-morphism (code obfuscation). This paper addresses the problem of detecting in network traffic polymorphic remote exploits that are encrypted, and that self-decrypt before launching the intrusion. Such exploits pose a great challenge to existing malware detection techniques, partly due to the non-obvious starting location of the exploit code in the network payload.We describe a new method for detecting self-decrypting exploit codes. This method scans network traffic for the presence of a decryption routine, which is characteristic of such exploits. The proposed method uses static analysis and emulated instruction execution techniques. This improves the accuracy of determining the starting location and instructions of the decryption routine, even if self-modifying code is used. The method outperforms approaches that have been previously proposed, both in terms of detection capabilities, and in detection accuracy.The proposed method has been implemented and tested on current polymorphic exploits, including ones generated by state-of-the-art polymorphic engines. All exploits have been detected (i.e., a 100% detection rate), including those for which the decryption routine is dynamically coded, or self-modifying. The false positive rate is close to 0%. Running time is approximately linear in the size of the network payload being analyzed.

Unsupervised Neural Machine Translation (2017)

In spite of the recent success of neural machine translation (NMT) in standard benchmarks, the lack of large parallel corpora poses a major practical problem for many language pairs. There have been several proposals to alleviate this issue with, for instance, triangulation and semi-supervised learning techniques, but they still require a strong cross-lingual signal. In this work, we completely remove the need of parallel data and propose a novel method to train an NMT system in a completely unsupervised manner, relying on nothing but monolingual corpora. Our model builds upon the recent work on unsupervised embedding mappings, and consists of a slightly modified attentional encoder-decoder model that can be trained on monolingual corpora alone using a combination of denoising and backtranslation. Despite the simplicity of the approach, our system obtains 15.56 and 10.21 BLEU points in WMT 2014 French-to-English and German-to-English translation. The model can also profit from small parallel corpora, and attains 21.81 and 15.24 points when combined with 100,000 parallel sentences, respectively. Our implementation is released as an open source project.

Cost-Effectiveness of Alternative Methods for Diabetic Retinopathy Screening (1992)

Primary-care screening with retinal photographs through pharmacologically dilated pupils for diabetic retinopathy is an appropriate and cost-effective alternative to screening by an ophthalmologist in this setting. Ophthalmologists are scarce, primary-care physicians are extremely busy, and large clinics allow fixed equipment costs to be spread across many patients.
MEANINGFUL STATISTICAL MODEL FORMULATIONS FOR REPEATED MEASURES (2004)

When choosing a parametric statistical model two important considerations are mathematical soundness and substantive relevance. In this paper, we illustrate and exemplify that a number of issues arise from these considerations, even in relatively simple settings, such as ordinal regression, linear mixed models, models for cross-classified data and generalized linear mixed models. Many of our points are illustrated with data.
Decreased expression of SCUBE2 is associated with progression and prognosis in colorectal cancer (2015)

Signal peptide-CUB-epidermal growth factor-like domain-containing protein 2 (SCUBE2), a member of the SCUBE protein family, is a secreted and membrane-associated multi-domain glycoprotein. SCUBE2 is known as a novel tumor suppressor and a useful prognostic marker in breast cancer. In the present study, we investigated the expression (including mRNA and protein levels) of SCUBE2 in colorectal cancer (CRC) and adjacent normal tissues, using quantitative real-time PCR, western blot analysis and immunohistochemistry on a tissue microarray. Upregulation of SCUBE2 was achieved by transient transfection in RKO cell lines, and the effects of SCUBE2 on tumor proliferation, invasion, migration and apoptosis were evaluated by a series of functional experiments. The results indicated that SCUBE2 expression was decreased at the transcriptional and translational levels in CRC tissues and significantly associated with clinical stage, the depth of tumor invasion, lymph‑node metastasis, distant metastasis and histological grade. Patients with SCUBE2‑positive tumors had a lower recurrence rate and better survival than patients with SCUBE2-negative tumors. Moreover, upregulation of SCUBE2 had a limited effect on cell apoptosis but significantly inhibited tumor cell proliferation, migration and invasion in vitro. In conclusion, SCUBE2 plays an important role in suppressing CRC progression and prognosis. Our findings suggested that SCUBE2 may serve as a novel tumor suppressor and a potential therapeutic target for CRC patients.
Actively controlled fibrillar friction surfaces (2015)

In this letter, we propose a technique by which we can actively adjust frictional properties of elastic fibrillar structures in different directions. Using a mesh attached to a two degree-of-freedom linear stage, we controlled the active length and the tilt angle of fibers, independently. Thus, we were able to achieve desired levels of friction forces in different directions and significantly improve passive friction anisotropies observed in the same fiber arrays. The proposed technique would allow us to readily control the friction anisotropy and the friction magnitude of fibrillar structures in any planar direction.
A Novel Demodulation Method Based on Zero-Crossing Detection for UWB Signal Reception (2009)

Easy implementation of receivers in practice is vital importance for the ultra wideband (UWB) system. This paper puts forward a novel noncoherent demodulation algorithm for UWB signal reception which detects UWB signal by using zero-crossing detection (ZCD) based on double thresholds. The description of algorithm, an analytical expression of the bit error ratio (BER) performance under the additive white Gaussian noise (AWGN) channel and simulation are provided. The results show that proposed method can remarkably obtain better BER performance than the energy detection with a little expense of complexity and greatly reduce complexity in comparison with coherent detection but about 1 dB performance degradation in AWGN channel.

Interface Effects for Cu, CuO, and Cu<sub>2</sub>O Deposited on SiO<sub>2</sub> and ZrO<sub>2</sub>. XPS Determination of the Valence State of Copper in Cu/SiO<sub>2</sub> and Cu/ZrO<sub>2</sub> Catalysts (2002)

Copper and copper oxides (Cu2O and CuO) have been deposited by evaporation of copper and subsequent oxidizing treatments, on the surface of flat SiO2 and ZrO2 substrates. Large variations of several eVs have been found in the values of the Cu 2p3/2 binding energy (BE) and Auger parameter (α‘) of copper as a function of the amount of deposited metallic copper or copper oxides. The magnitude of the changes was also dependent on the type of support upon which the experiment was carried out. These changes have been attributed to modifications in the factors contributing to the initial and final state effects of the process, according to the dispersion degree and the nature of the interactions between the copper oxide moieties and the support. All of these changes can be systematized with the help of chemical state plots. Experiments carried out with real catalysts stress the need of such plots, which summarize the results obtained with the model systems, for a proper characterization of the supported oxide phases in this kind of real materials.

Mammalian Sterile 20–like Kinase 1 Suppresses Lymphoma Development by Promoting Faithful Chromosome Segregation (2012)

The mammalian Hippo signaling pathway has been implicated in oncogenesis in the context of solid tumors such as hepatocellular carcinoma. Mammalian sterile 20-like kinase 1 (MST1), the core component of the Hippo signaling pathway, is highly expressed in hematopoietic cells. However, its possible impact on tumorigenesis in this setting is unknown. In this study, we provide evidence that Mst1 loss in the mouse enhances chemically and genetically induced lymphoma development by inducing chromosomal instability. Mst1 deficiency increased susceptibility to T-cell acute lymphoblastic leukemia induced by mutagen exposure. Notably, before transformation Mst1(-/-) normal thymocytes showed no changes in proliferation or apoptosis in vitro and in vivo, but they displayed elevated levels of abnormal mitotic chromosomes and aneuploidy, conditions known to promote tumorigenesis. Mst1(-/-) mice also showed accelerated formation of spontaneous lymphomas in a p53-deficient background, accompanied by severe aneuploidy. In clinical specimens of lymphoma and leukemia, we documented frequent downregulation of MST1 expression, consistent with our findings. Taken together, our findings reveal a tumor suppressive function of Mst1 based on its ability to prevent chromosomal instability in lymphocytes.
Ultrasonographically defined parenchymal patterns of the breast: relationship to mammographic patterns and other risk factors for breast cancer (1988)

We have used ultrasound of the breast to define four parenchymal patterns in which increasing proportions of the breast are replaced by densely echogenic tissue. A series of 452 symptomatic women examined by both ultrasound and conventional X-ray mammography was reviewed to determine whether these ultrasonographic images could predict the breast parenchymal pattern defined mammographically. A very strong correlation was demonstrated between the breast pattern on ultrasound and the volume of the breast replaced by either dysplasia (Kendall's tau-b = 0.731 +/- 0.026, p less than 0.0001) or ductal prominence (Kendall's tau-b = 0.641 +/- 0.049, p less than 0.0001). This was seen both on initial reporting and on a blind re-reading of a random sample of 100 cases. The strength of correlation was similar for subgroups defined by family history of breast cancer, age, menopausal status, and history of benign breast disease, and the breast parenchymal pattern assessed by mammography or ultrasound showed similar associations with these variables. Ultrasonographic parenchymal patterns of the breast can predict the tissue patterns defined mammographically and may therefore be useful as a marker of breast cancer risk.
Dopaminergic sensitivity and prediction of antidepressant response (2000)

This study was designed to examine neuroendocrine predictors of antidepressant response to the selective serotonin reuptake inhibitor (SSRI) paroxetine. We assessed the prognostic utility of the apomorphine stimulation test by examining the relationship between pretreatment change in growth hormone (GH) following apomorphine and acute response to paroxetine treatment. We hypothesized that those subjects with most marked pretreatment dopaminergic supersensitivity, as manifested by greatest change in GH, would be most likely to show an early antidepressant response and would also be more likely to develop manic or hypomanic symptoms on paroxetine. Contrary to our hypothesis, greater dopamine postsynaptic sensitivity was associated with greater resistance to paroxetine treatment. In our sample of 13 subjects with a major depressive episode, pretreatment GH response to apomorphine per unit weight was inversely correlated with change in Hamilton depression rating scale following 6 weeks of paroxetine. Within the group of subjects who showed mood elevation on paroxetine, there was a trend towards greater GH response being associated with slower antidepressant response. With regard to the development of manic or hypomanic symptoms on paroxetine, change in GH per unit weight not did distinguish the two subjects who subsequently developed paroxetine-induced hypomania from other subjects. The seven subjects with previous antidepressant-induced hypomania did not differ from the other subjects in change in GH response per unit weight. The finding that subjects who had low dopamine receptor responsivity pretreatment were more likely to have an antidepressant response with paroxetine is consistent with recent suggestions that the therapeutic effect of SSRIs may be mediated through increased dopamine receptor sensitivity in the mesolimbic system. Further work assessing pretreatment and post-treatment GH response to apomorphine will help to test the hypothesis that low dopamine receptor responsivity predicts antidepressant response to SSRIs.
Rendering computer animations on a network of workstations (2002)

Rendering high-quality computer animations requires intensive computation, and therefore a large amount of time. One way to speed up this process is to devise rendering algorithms which reduce computation by taking advantage of image characteristics, such as frame or temporal coherence. Another way is to run the rendering process on specialized or enhanced hardware, such as a multiprocessor machine. This paper details our experiences in combining these techniques through a parallel rendering algorithm exploiting frame coherence run on a network of workstations acting as a single processing system. This system provides a powerful and general method for obtaining high-quality animations with a significant reduction in computation and overall processing time. We present several techniques for partitioning the data across the workstation processors and report our results for each. While all of the partitioning schemes are scalable, some handle load balancing more effectively than others.
