PREDICTIVE POTENTIAL FIELD-BASED COLLISION AVOIDANCE FOR MULTICOPTERS (2013)

Abstract. Reliable obstacle avoidance is a key to navigating with UAVs in the close vicinity of static and dynamic obstacles. Wheel-based mobile robots are often equipped with 2D or 3D laser range finders that cover the 2D workspace sufficiently accurate and at a high rate. Micro UAV platforms operate in a 3D environment, but the restricted payload prohibits the use of fast state-of-the-art 3D sensors. Thus, perception of small obstacles is often only possible in the vicinity of the UAV and a fast collision avoidance system is necessary. We propose a reactive collision avoidance system based on artificial potential fields, that takes the special dynamics of UAVs into account by predicting the influence of obstacles on the estimated trajectory in the near future using a learned motion model. Experimental evaluation shows that the prediction leads to smoother trajectories and allows to navigate collision-free through passageways.
Association between protective efficacy of anti-lipopolysaccharide (LPS) antibodies and suppression of LPS-induced tumor necrosis factor alpha and interleukin 6. Comparison of O side chain-specific antibodies with core LPS antibodies. (1990)

Two-core LPS antibodies, the rabbit J5 polyclonal antiserum and the human anti-lipid A IgM mAb HA-1A, did not improve the survival of mice challenged with E. coli O111 or P. aeruginosa 3, or with the LPS extracted from them, and did not decrease the incidence of Shwartzman reactions in rabbits challenged with O111 LPS. In contrast, O side chain-specific rabbit antisera were protective in these models. The protection afforded by O side chain-specific antisera against endotoxin lethality was associated with decreased LPS-induced serum TNF and IL-6 levels, whereas core LPS antibodies had no effect on TNF or IL-6 levels. The absence of reduction of LPS-induced cytokines levels by core LPS antibodies suggests that these antibodies are not able to prevent the interactions between LPS and target cells.
The genetics and embryology of zebrafish metamerism (2007)

Somites are the most obvious metameric structures in the vertebrate embryo. They are mesodermal segments that form in bilateral pairs flanking the notochord and are created sequentially in an anterior to posterior sequence concomitant with the posterior growth of the trunk and tail. Zebrafish somitogenesis is regulated by a clock that causes cells in the presomitic mesoderm (PSM) to undergo cyclical activation and repression of several notch pathway genes. Coordinated oscillation among neighboring cells manifests as stripes of gene expression that pass through the cells of the PSM in a posterior to anterior direction. As axial growth continually adds new cells to the posterior tail bud, cells of the PSM become relatively less posterior. This gradual assumption of a more anterior position occurs over developmental time and constitutes part of a maturation process that governs morphological segmentation in conjunction with the clock. Segment morphogenesis involves a mesenchymal to epithelial transition as prospective border cells at the anterior end of the mesenchymal PSM adopt a polarized, columnar morphology and surround a mesenchymal core of cells. The segmental pattern influences the development of the somite derivatives such as the myotome, and the myotome reciprocates to affect the formation of segment boundaries. While somites appear to be serially homologous, there may be variation in the segmentation mechanism along the body axis. Moreover, whereas the genetic architecture of the zebrafish, mouse, and chick segmentation clocks shares many common elements, there is evidence that the gene networks have undergone independent modification during evolution.
Feedforward learning applied to RTP of semiconductor wafers (2002)

Our recent algorithmic results (1994) in feedforward learning control (LC) are applied to the control of semiconductor wafer temperature in a rapid thermal processing (RTP) reactor. Although the first attempt is experimental in nature, the results are very encouraging and deserve serious consideration. Applying this LC approach has resulted in a speed-up of a well-tuned feedback loop by a factor of 8 which amounts to more than 20 seconds saving in one processing step-quite significant for RTP. Additionally, the experiment has demonstrated the applicability of the LC theory in a real-world manufacturing setting. Many repetitive manufacturing tasks are potential applications of this LC procedure.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Input device using eye tracker in human-computer interaction (2002)

This paper describes the development of the eye-gazing input system using the eye tracking system. The eye-gazing input system consists of a subsystem that detects the user's eye movement and a subsystem that calculates the coordinate of the mouse pointer from the eye movement patterns. This paper mainly describes the algorithm to calculate the coordinate of pointer from eye movements and the usability of the input system for the configuration of a selected object. The usability of the developed input system using eye movement is discussed by comparing it with the computer mouse. In this investigation, the size, moving distance and moving direction are considered as the configuration of the objects, and the effect of the configuration of buttons on pointing time using an eye-gazing input system is analyzed.
Analysis of Intact Cholesteryl Esters of Furan Fatty Acids in Cod Liver (2015)

Furan fatty acids (F-acids) are a class of natural antioxidants with a furan moiety in the acyl chain. These minor fatty acids have been reported to occur with high proportions in the cholesteryl ester fraction of fish livers. Here we present a method for the direct analysis of intact cholesteryl esters with F-acids and other fatty acids in cod liver lipids. For this purpose, the cholesteryl ester fraction was isolated by solid phase extraction (SPE) and subsequently analyzed by gas chromatography with mass spectrometry (GC/MS) using a cool-on-column inlet. Pentadecanoic acid esterified with cholesterol was used as an internal standard. GC/MS spectra of F-acid cholesteryl esters featured the molecular ion along with characteristic fragment ions for both the cholesterol and the F-acid moiety. All investigated cod liver samples (n = 8) showed cholesteryl esters of F-acids and, to a lower degree, of conventional fatty acids. By means of GC/MS-SIM up to ten F-acid cholesteryl esters could be determined in the samples. The concentrations of cholesteryl esters with conventional fatty acids amounted to 78-140 mg/100 g lipids (mean 97 mg/100 g lipids), while F-acid cholesteryl esters were present at 47-270 mg/100 g lipids (mean 130 mg/100 g lipids).
SOAP to SNOCAMP: improving the medical record format. (1995)

Not since the development of the SOAP note in the problem-oriented medical record has there been a significant need to alter the format of medical record documentation. With the intrusion of third-party audits, malpractice attorney subpoenas, medical guidelines, and reimbursement code criteria into the practice of medicine, there is a need to expand the traditional SOAP note. This article proposes a new acronym, "SNOCAMP," for medical record documentation. SNOCAMP retains the SOAP format, which includes subjective, objective, assessment, and plan of treatment, with the addition of nature of the presenting complaint, counseling, and medical decision-making. It is hoped that this new, more explicit format will prove successful in meeting the divergent needs of practicing physicians, the patients they serve, and the inquiring minds that look over their shoulders.
Cytochrome Display on Amyloid Fibrils (2006)

Protein amyloid fibrils can be functionalized by coating the core protofilament with high concentrations of proteins and enzymes. This can be done elegantly by appending a functional domain to an amyloidogenic protein monomer, then assembling the monomers into a fibril. To display an array of biologically functional porphyrins on the surface of protein fibrils, we have fused the sequence of the small, soluble cytochrome b562 to an SH3 dimer sequence that can form classical amyloid fibrils rapidly under well-defined conditions. The resulting fusion protein also forms amyloid fibrils and, in addition, binds metalloporphyrins, at half of the porphyrin binding sites as shown by UV-vis and NMR spectroscopies. Once metalloporphyrins are bound to the fibrils, the resulting holo-cytochrome domains are spectroscopically identical to the wild type cytochrome. The concentration of metalloporphyrins on a saturated fibril is estimated to be of the order of approximately 20 mM, suggesting that they could be interesting systems for applications in nanotechnology.
Bimolecular Interaction of Insulin-Like Growth Factor (IGF) Binding Protein-2 with αvβ3 Negatively Modulates IGF-I-Mediated Migration and Tumor Growth (2004)

Both the integrin and insulin-like growth factor binding protein (IGFBP) families independently play important roles in modulating tumor cell growth and progression. We present evidence for a specific cell surface localization and a bimolecular interaction between the alpha v beta 3 integrin and IGFBP-2. The interaction, which could be specifically perturbed using vitronectin and alpha v beta 3 blocking antibodies, was shown to modulate IGF-mediated cellular migration responses. Moreover, this interaction was observed in vivo and correlated with reduced tumor size of the human breast cancer cells, MCF-7 beta 3, which overexpressed the alpha v beta 3 integrin. Collectively, these results indicate that alpha v beta 3 and IGFBP-2 act cooperatively in a negative regulatory manner to reduce tumor growth and the migratory potential of breast cancer cells.
Neuroectoderm-associated antigens on Ewing's sarcoma cell lines. (1987)

The histogenesis of Ewing's sarcoma, the second most frequent primary bone tumor in humans, remains controversial. Ten Ewing cell lines were analyzed by immunological methods. Surface antigens recognized on Ewing cells were found to be related to the neuroectoderm lineage. They included ganglioside GD2, a marker of neuroectodermal tissues and tumors, and an acidic glycolipid detected by monoclonal antibody HNK-1 in the nervous system. The P61 rat monoclonal antibody that reacts with a peptide moiety of neural cell adhesion molecule (N-CAM) and a rabbit antiserum raised to purified mouse N-CAM also stained Ewing cells. Flow cytometry analysis performed using these reagents allowed the definition of four distinct Ewing phenotypes: all reagents equally stained group 1 lines; group 2 lines were strongly reactive with anti-N-CAM reagents, by contrast with a fainter staining with HNK-1 and anti-GD2 antibodies; all reagents but P61 were strongly reactive with group 3 lines; in group 4, Ewing lines were stained by P61 but only poorly by the anti-N-CAM antiserum. Several antibodies to melanoma and neuroblastoma associated antigens including two monoclonal antibodies to the nerve growth factor receptor were also found to react with Ewing cells. By contrast, all antibodies detecting antigens specifically expressed in hematopoietic cell lineages were totally unreactive. HLA class II antigens were never detected while the level of expression of class I antigens varied to a large extent. Ewing cells are characterized by a specific t(11;22)(q23-24;q12) translocation also observed in neuroepithelioma, a neuroectodermal tumor. Thus, Ewing's sarcoma cells share antigenic and karyotypic features with derivatives of the neuroectoderm possibly indicating a related histogenesis.

Disinformation: An instrumentality in the propaganda arsenal (1982)

Abstract The term “disinformation” as a persuasive technique that is based on forgeries and staged events was invented by the KGB, the Soviet secret service. Although disinformation has been used by most states, the Soviets have perfected it as an instrument of public policy. Disinformation comprises two parts: a forgery or fabrication, and the publicity that accompanies it to effectuate some psychological advantage for the originator of the disinformation. It is the falsification or staged event accompanying the persuasive message that distinguishes disinformation from run‐of‐the‐mill propaganda. This article suggests that no state would resort to disinformation if the truth and the actual course of events were operating in its favor.
The preparation of D‐glucaric acid by oxidation of molasses in packed beds (2001)

An attempt has been made to prepare glucaric acid by oxidation of sugar beet molasses in packed beds. In the first part, a suitable oxidizing medium was sought. Experiments were performed in a cylindrical Pyrex-glass reactor with air–molasses cocurrent downflow. Spherical glass and cylindrical vanadium pentoxide particles were used as an inert packing and catalyst respectively. The addition of catalyst, sodium nitrite, nitric and sulfuric acids to the medium resulted in an improvement in glucaric acid yield. The presence of nitric acid in the oxidizing medium and the use of vanadium pentoxide catalyst were the most effective factors as regards the yield. In the second part, the effects of temperature, molasses concentration, amount of catalyst and air flow rate on the yield were studied; each of these variables increased the yield. The use of a longer catalyst bed, however, resulted in a decrease in the yield. The highest rate of conversion of glucose to glucaric acid was 63.9% at optimum conditions. © 2001 Society of Chemical Industry
L-SR1: A Second Order Optimization Method for Deep Learning (2017)

We describe L-SR1, a new second order method to train deep neural networks. Second order methods hold great promise for distributed training of deep networks. Unfortunately, they have not proven practical. Two significant barriers to their success are inappropriate handling of saddle points, and poor conditioning of the Hessian. L-SR1 is a practical second order method that addresses these concerns. We provide experimental results showing that L-SR1 performs at least as well as Nesterov's Accelerated Gradient Descent, on the MNIST and CIFAR10 datasets. For the CIFAR10 dataset, we see competitive performance on shallow networks like LeNet5, as well as on deeper networks like residual networks. Furthermore, we perform an experimental analysis of L-SR1 with respect to its hyper-parameters to gain greater intuition. Finally, we outline the potential usefulness of L-SR1 in distributed training of deep neural networks.

Membrane detachment and release of the major membrane glycoprotein of secretory granules in rat pancreatic exocrine cells. (1985)

The major glycoprotein of pancreatic zymogen granule membranes (GP-2) was detected in the medium of acinar cell suspensions from rat pancreas. Its release from the cells was studied in pulse-chase metabolic labeling experiments with radioactive methionine. GP-2 (apparent Mr = 80 000) was found to be processed to a form of slightly lower apparent Mr (75 000) after about 4 h chase. At about the same time this smaller form of GP-2 appeared in the medium. These results are in accordance with earlier findings in vivo. At different chase times acinar cells were extracted with Triton X-114 to separate water-soluble proteins from membrane-associated (hydrophobic) proteins. This experiment showed that GP-2 is slowly converted from a membrane-bound glycoprotein to a soluble glycoprotein after its reduction in apparent molecular mass, causing its detachment from the membrane. Further analysis indicated that the detachment process may occur at the zymogen granule membrane as well as the plasma membrane. Immunocytochemistry on ultrathin cryosections of pancreatic tissue showed that GP-2 is localized on zymogen granule membranes, plasma membranes and in the acinar lumen. Although in much smaller quantities, GP-2 is also present in the granule content. Thus, in summary, GP-2 is synthesized as a true membrane glycoprotein which is gradually processed to a soluble species and is found in the secretion.
Subjective versus objective measures of daily listening environments (2007)

This study examined hearing impaired listeners’ subjective perceptions of listening environments through a listening questionnaire and compared these results to objective measures mimicked by the questionnaire in the datalogging device SAM (Sound Activity Meter). Results indicate audiologists should not rely on patient reports of “typical” listening environments for hearing aid selection as significant discrepancies were present between several of the subjective and objective measures.
Characterization of Native and Modified Extensin Monomers and Oligomers by Electron Microscopy and Gel Filtration (1988)

We isolated hydroxyproline-rich extensin precursors from suspension-cultured tomato, cucumber, and sycamore-maple by salt-elution of intact cells and cell wall preparations. Cation exchange chromatography and HPLC gel filtration resolved these precursors into monomeric and oligomeric fractions, confirmed by amino acid analysis, immunological cross-reactivity, and TEM visualization. After rotary shadowing monomers appeared as flexuous rods with a contour length of 70 to 100 nanometers and a ;persistence length' (maximum linear displacement) of 44 to 51 nanometers. Oligomers were larger branched assemblies with occasional pores. Native extensin monomers gave uniform gel filtration retention times (Rts), but the Rts of HF-deglycosylated monomers varied depending on concentration, implying ionic interaction between the highly basic deglycosylated monomers and a weakly cationic gel matrix. Succinylation of the deglycosylated monomers reversed the net charge, and restored the retention time to that of glycosylated monomers, confirming the ionic interaction. Succinylation enhanced visualization of the deglycosylated monomers, which previously were barely discernible flexuous rods. The persistence length:contour length ratios of succinylated deglycosylated monomers (tomato sdP2) and glycosylated monomers (sP2) were the same, implying a similar molecular flexibility for both glycosylated and deglycosylated monomers at room temperature. These molecular properties are consistent with suggestions that extensin monomers reptate into the wall as a transmural protein ;weft' which becomes progressively cross-linked forming a network penetrated by the cellulose ;warp.'
Modeling insider attacks on group key-exchange protocols (2005)

Protocols for authenticated key exchange (AKE) allow parties within an insecure network to establish a common session key which can then be used to secure their future communication. It is fair to say that group AKE is currently less well understood than the case of two-party AKE; in particular, attacks by malicious insiders --- a concern specific to the group setting --- have so far been considered only in a relatively "ad-hoc" fashion. The main contribution of this work is to address this deficiency by providing a formal, comprehensive model and definition of security for group AKE which automatically encompasses insider attacks. We do so by defining an appropriate ideal functionality for group AKE within the universal composability (UC) framework. As a side benefit, any protocol secure with respect to our definition is secure even when run concurrently with other protocols, and the key generated by any such protocol may be used securely in any subsequent application.In addition to proposing this definition, we show that the resulting notion of security is strictly stronger than the one proposed by Bresson, et al. (termed "AKE-security"), and that our definition implies all previously-suggested notions of security against insider attacks. We also show a simple technique for converting any AKE-secure protocol into one secure with respect to our definition.
Friedel–Crafts reactions of alkenones with benzene (1973)

The Friedel–Crafts reactions of benzene with hex-3-en-2-one, hex-4-en-2-one, hex-5-en-2-one, hept-3-en-2-one, hept-4-en-2-one, oct-3-en-2-one, oct-4-en-2-one, oct-5-en-2-one, oct-6-en-2-one, oct-7-en-2-one, and 5-methylhex-5-en-2-one are reported. Hex-4-en-2-one and hex-5-en-2-one both yielded 5-phenylhexan-2-one as the sole monophenylation product. Each of the other ketones gave a mixture of phenylated alkanones, the composition of which depended on the position of the double bond relative to the carbonyl group in the starting ketone.
