On Time Optimization of Centroidal Momentum Dynamics (2018)

Recently, the centroidal momentum dynamics has received substantial attention to plan dynamically consistent motions for robots with arms and legs in multi-contact scenarios. However, it is also non convex which renders any optimization approach difficult and timing is usually kept fixed in most trajectory optimization techniques to not introduce additional non convexities to the problem. But this can limit the versatility of the algorithms. In our previous work, we proposed a convex relaxation of the problem that allowed to efficiently compute momentum trajectories and contact forces. However, our approach could not minimize a desired angular momentum objective which seriously limited its applicability. Noticing that the non-convexity introduced by the time variables is of similar nature as the centroidal dynamics one, we propose two convex relaxations to the problem based on trust regions and soft constraints. The resulting approaches can compute time-optimized dynamically consistent trajectories sufficiently fast to make the approach realtime capable. The performance of the algorithm is demonstrated in several multi-contact scenarios for a humanoid robot. In particular, we show that the proposed convex relaxation of the original problem finds solutions that are consistent with the original non-convex problem and illustrate how timing optimization allows to find motion plans that would be difficult to plan with fixed timing <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">†</sup> †Implementation details and demos can be found in the source code available at https://git-amd.tuebingen.mpg.de/bponton/timeoptimization.
Who do you say I am (1990)

About seven or eight years ago, a couple of researchers in sociology and psychology published a book with the title "The First Four Minutes".It was the thesis of these authors that all relationships are completely determined in the four minutes after people first meet.In four minutes we decide whether a person we have just met will become a casual acquaintance, a close friend, our husband or wife, a bitter enemy; or we decide to let that person walk through our life, and out of it, never to be seen again!If that is correct, then it puts clergy like me, taking their first service and preaching their first sermon in a new parish, under great pressure.After all, I want my relationship with you to go well.According to this theory, I've got about three minutes left, if you count from the start of the sermon, or
Magnetic alignment of aqueous CTAB in nematic and hexagonal liquid crystalline phases investigated by spin-1 NMR (2006)

Spin-1 NMR has been used to characterize the magnetically aligned nematic and hexagonal liquid crystalline phases of aqueous cetyltrimethylammonium bromide (CTAB). A nematic/hexagonal biphasic region has been identified for the first time in this system. The nematic phase is characterized by an order parameter of smaller magnitude and greater temperature dependence. Magnetic alignment kinetic rates of the two phases differ greatly, with the nematic phase showing magnetic alignment much faster than the hexagonal phase. Equilibration has been monitored over time by measuring the change in quadrupole splitting as a function of temperature. As the sample equilibrates the temperature dependence of the splitting decreases logarithmically. This work also demonstrates how the phase and order of the liquid crystal can be manipulated during the early part of equilibration.
Quantification and evaluation of human tactile sense towards fabrics (2006)

This paper introduces a novel approach for evaluating fabric sensory responses. First, the problems in existing techniques are analyzed, and by comparing with successful cases in assessing human feeling towards cold/warmth and human color sense, a more scientific scheme based on the computer pattern recognition technique is exhibited and the details of the measurements, data processing and calculation of the ultimate parameters are introduced. The actual prototype of the instrument and related details are also provided. Finally, it is shown that the technique can also be utilized to evaluate some visual attributes such as drape and wrinkle recovery.

A dose computation model for <sup>2</sup><sup>4</sup><sup>1</sup>Am vaginal applicators including the source‐to‐source shielding effects (1990)

A dose computation model has been developed for the determination of dose distributions around vaginal plaque applicators containing encapsulated 241Am sources. Encapsulated sources of 241Am emit primarily 60-keV photons which have a half-value layer thickness of 1/8 mm of lead. This makes possible highly effective in vivo shielding of normal tissues at risk, by placing thin lead shields at appropriate places on the applicator. However, self-absorption of photons in the source material itself is intense, requiring bulky sources of about 1 cm diameter. These sources also produce considerable source-to-source shielding which must be taken into account in dose calculations. Our dose computation model for a single source employs three-dimensional integration of dose contributions from volume elements of the source including the effects of absorption and scattering of photons in the source material, titanium encapsulation, and water. An empirical correction to Berger's data on buildup factors of point, isotropic sources is made to account for the effects of anisotropic photon emission by cylindrical 241Am sources. The second part of our dose computation model takes into account source-to-source shielding effects on both primary and scattered photons for the vaginal plaque geometry. The results of the model have been verified for accuracy by comparisons with extensive dosimetry measurements using lithium fluoride thermoluminescent dosimeters.

The epidemiology of human papillomavirus infections (2005)

Infection with oncogenic human papillomavirus (HPV) types is a necessary cause of cervical cancer, the second most frequently occurring cancer in women worldwide. Rates of acquisition of HPV are high, particularly among sexually active young adults. Reported estimates of incident HPV infection among initially negative women have reached as high as 60% over a 5-year follow-up period. In this article, we review the epidemiology of HPV infection. In addition to estimates of disease frequency, we highlight risk factors for HPV infection, including the number of lifetime sex partners, which is the most salient risk factor. We discuss significant issues surrounding the natural history of HPV infection, including viral persistence versus clearance, immune response, development of lesions and development of cancer. Finally, we discuss strategies for preventing HPV infection.
Drinking Water Regulatory Priorities (2017)

Drinking water was the center of attention in 2016. There is good reason to believe the sector should expect reinvestment in water infrastructure, and ensuring that the public has safe drinking water will continue to be highlighted for the foreseeable future. US federal policy development is not a rapid process, which can be frustrating for some, but the current system provides for more substantiated decisions. It also gives local communities time to learn and make decisions to try to balance multiple demands over longer time frames.
An activated c-Ha-ras allele blocks the induction of muscle-specific genes whose expression is contingent on mitogen withdrawal. (1987)

During myogenesis, induction of muscle-specific genes is subject to negative control by polypeptide mitogens and type-beta transforming growth factor. Since transduction of growth factor signals may require proteins encoded by cellular ras oncogenes, we have tested whether a mutationally altered Harvey ras expression vector, by itself, can prevent establishment of a differentiated phenotype in BC3H1 mouse myoblasts. Transfection with the valine-12 allele of the human Harvey ras gene, under the control of its own promoter, was sufficient to prevent the induction of both muscle creatine kinase activity and the nicotinic acetylcholine receptor following mitogen withdrawal but did not inhibit withdrawal from the cell cycle. The loss of creatine kinase activity resulted from a corresponding block to induction of muscle creatine kinase mRNA. Similarly, mitogen withdrawal elicited little or no alpha-actin mRNA in ras-transfected cells. These results suggest that an activated ras allele can inhibit myogenesis through a mechanism independent of cell proliferation and can preclude activation of genes whose up-regulation normally accompanies mitogen withdrawal.
Conductive Core–Shell Particles: An Approach to Self‐Assembled Mesoscopic Wires (2003)

Conductive core–shell particles consisting of a dielectric core and a metallic shell were prepared using layer‐by‐layer assembly and electroless plating. Conductivity was studied using X‐ray photoelectron spectroscopy and UV‐vis spectroscopy as a function of the preparation protocol. Routines for the controlled self‐assembly of these particles into continuous lines (see Figure and cover) were investigated to explore their applicability in self‐assembled mesoscopic wiring.
Five‐year experience with incobotulinumtoxinA (Xeomin<sup>®</sup>): the first botulinum toxin drug free of complexing proteins (2011)

In 2005, incobotulinumtoxinA (Xeomin ® ), a new botulinum toxin (BT) type A drug without complexing proteins (CPs), became available. This paper reviews the specific features of Xeomin ® and the experience gathered with it during the last 5 years. Compared with conventional BT drugs, Xeomin ® ’s extended shelf live and its simplified temperature restrictions indicate that CPs are not necessary for BT drug stability. Its reduced molecular size does not translate into diffusion differences, and its potency labelling is identical to that of onabotulinumtoxinA (Botox ® ). With a reduced content of inactivated botulinum neurotoxin, Xeomin ® should have reduced antigenicity. Lack of CP’s may further reduce antigenicity. Xeomin ® ’s therapeutic efficacy against cervical dystonia, blepharospasm and spasticity has been proven in large randomised, double‐blind and placebo‐controlled studies leading to registrations in many countries. Additional successful clinical use in axillary hyperhidrosis, hemifacial spasm, re‐innervation synkinesias and hypersalivation as well as in dystonia and spasticity in extended doses and throughout extended observation periods has been documented meanwhile. Lack of reported cases of antibody‐induced therapy failure (ABF), as to date, support the hypothesis of an improved antigenicity.
Development of Multiple Cloning Site <i>cis</i>-Vectors for Recombinant Adeno-Associated Virus Production (2002)

Recombinant adeno-associated virus (rAAV) has become a very popular gene therapy vector in the past several years. A cis-plasmid is used to generate the rAAV stocks. In this plasmid, the entire expression cassette is incorporated between two AAV inverted terminal repeats. The construction of cis-plasmid has been problematic because of the high-frequency recombination of the viral inverted terminal repeats. Here we describe the design and construction of several multiple cloning site cis-plasmids that are driven by five different promoters, including the ubiquitous cytomegalovirus enhancer/chicken β-actin (CAG), cytomegalovirus (CMV), rous sarcoma virus (RSV), simian virus 40 (SV40), and a muscle-specific promoter (CK6). The application of these multiple cloning site cis-plasmids improves the cloning efficiency. As an example of the utilization of these multiple cloning site vectors, the prokaryotic β-galactosidase cDNA was cloned in the multiple cloning site cis-plasmids. High-level rAAV-mediated β-galactosidase expression was achieved in HeLa cells from CAG, CMV, RSV, and SV40 promoters, respectively, but not from the CK6 promoter. In vivo application in the adult mdx mouse (mouse model for Duchenne muscular dystrophy) muscle revealed efficient transgene expression from CMV and CK6 promoters, followed by CAG and RSV promoters. The SV40 promoter was the least efficient.
Kalman filter incorporated model updating for real-time tracking (2002)

This paper describes a real-time tracking system which detects an object entering into the field of view of a camera and executes the tracking of the detected object by controlling a servo device so that a target object always lies at the center of the image frame. In order to detect and track a moving object, we basically apply a model matching strategy. We allow the model to vary dynamically during the tracking process so that it can assimilate the variations of shape and intensities of the target object. We also utilize a Kalman filter so that a tracking history can be encoded into the state parameters of the Kalman filter. The estimated state parameters of the Kalman filter is then used to reduce the search areas for model matching and to control the servo device.
Integrins and chondrocyte–matrix interactions in articular cartilage (2014)

The integrin family of cell adhesion receptors plays a major role in mediating interactions between cells and the extracellular matrix. Normal adult articular chondrocytes express α1β1, α3β1, α5β1, α10β1, αVβ1, αVβ3, and αVβ5 integrins, while chondrocytes from osteoarthritic tissue also express α2β1, α4β1, α6β1. These integrins bind a host of cartilage extracellular matrix (ECM) proteins, most notably fibronectin and collagen types II and VI, which provide signals that regulate cell proliferation, survival, differentiation, and matrix remodeling. By initiating signals in response to mechanical forces, chondrocyte integrins also serve as mechanotransducers. When the cartilage matrix is damaged in osteoarthritis, fragments of fibronectin are generated that signal through the α5β1 integrin to activate a pro-inflammatory and pro-catabolic response which, if left unchecked, could contribute to progressive matrix degradation. The cell signaling pathways activated in response to excessive mechanical signals and to fibronectin fragments are being unraveled and may represent useful therapeutic targets for slowing or stopping progressive matrix destruction in arthritis.

Immunoglobulins of the leopard shark. I. Isolation and characterization of 17 S and 7 S immunoglobulins with precipitating activity. (1967)

1. 1. The rate of antibody production by the leopard shark, Triakis semifasciata was studied. Two immunoglobulins were elicited, first a 17 S macroglobulin and as intensive immunization continued increasing amounts of 7 S immunoglobulin.

2. 2. Both immunoglobulins were active as phage neutralizing antibodies and contained precipitating antibodies as measured by a microprecipitin test using I125 hemocyanin antigen.

3. 3. Shark immunoglobulins were produced at a slower rate than rabbit or mouse antibodies in response to similar antigenic challenge, and on a weight basis shark antibody precipitated or neutralized less antigen.

4. 4. When studied as antigens using rabbit antishark serum the 7 S and 17 S immunoglobulins appear to be identical. Both are inactivated to the same extent by a reducing agent, dithioerythritol. Dithioerythritol splits the 17 S protein to 7 S units which are antigenically identical with the original 17 S and 7 S proteins.

5. 5. The heavy and light chains derived from each of the immunoglobulins are indistinguishable when tested as antigens with rabbit anti-shark serum.
Loss and index change in GaInAsP/InP multiple quantum well QCSE tuning element for surface emitting lasers (2002)

The authors investigated some fundamental characteristics of chemical beam epitaxy (CBE) grown GaInAsP/InP multiple quantum wells (MQWs) for a wavelength tuner and estimated the wavelength shift for realizing wavelength tunable surface emitting (SE) lasers. They observed the quantum confined Stark effect in a GaInAsP/InP MQW structure grown by CBE and estimated the refractive index change, which was as large as 1%. By using these results, the possibility realizing a wavelength tunable SE laser with a MQW tuner is exhibited and the maximum wavelength change is expected to be as large as 7/spl Aring/.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Proteasome Parts at Gene Promoters (2002)

The proteasome is a garbage disposal unit in eukaryotic cells that degrades proteins tagged with ubiquitin molecules. In their Perspective, [Ottosen and colleagues][1] discuss new findings ([ Gonzalez et al .][2]) revealing that certain components of the proteasome may be involved in processes other than protein degradation. Six ATPases in the base section of the 19 S proteasomal subcomplex are recruited to sites of gene activation, suggesting that they may be involved in transcription.

Cooperative Interdomain Traffic Engineering Using Nash Bargaining and Decomposition (2009)

We present a novel approach to interdomain traffic engineering based on the concepts of Nash bargaining and dual decomposition. Under this scheme, ISPs use an iterative procedure to jointly optimize a social cost function, referred to as the Nash product. We show that the global optimization problem can be separated into subproblems by introducing appropriate shadow prices on the interdomain flows. These subproblems can then be solved independently and in a decentralized manner by the individual ISPs. Our approach does not require the ISPs to share any sensitive internal information, such as network topology or link weights. More importantly, our approach is provably Pareto-efficient and fair. Therefore, we believe that our approach is highly amenable to adoption by ISPs when compared to past approaches. We also conduct simulation studies of our approach over several real ISP topologies. Our evaluation shows that the approach converges quickly, offers equitable performance improvements to ISPs, is significantly better than unilateral approaches (e.g., hot-potato routing) and offers the same performance as a centralized solution with full knowledge.
Nanostructured Electrodes and the Low‐Temperature Performance of Li‐Ion Batteries (2005)

Template-synthesized V2O5 nanostructured electrodes (see Figure and cover) are used as tools for fundamental investigations into the poor low-temperature performance of Li-ion batteries. The electrodes consisted of nanofibers of V2O5, and by controlling the dimensions of the nanofibers it has been determined that the rate-limiting factor at low temperatures is the concentration polarization of the Li ion in the electrode material.
