Morphable 3D models from video (2001)

Nonrigid 3D structure-from-motion and 2D optical flow can both be formulated as tensor factorization problems. The two problems can be made equivalent through a noisy affine transform, yielding a combined nonrigid structure-fromintensities problem that we solve via structured matrix decompositions. Often the preconditions for this factorization are violated by image noise and deficiencies of the data visa-vis the sample complexity of the problem. Both issues are remediated with careful use of rank constraints, norm constraints, and integration over uncertainty in the intensity values, yielding novel solutions for SVD under uncertainty, factorization under uncertainty, nonrigid factorization, and subspace optical flow. The resulting integrated algorithm can track and 3D-reconstruct nonrigid surfaces that have very little texture, for example the smooth parts of the face. Working with low-resolution low-texture “found video, ” these methods produce good tracking and 3D reconstruction results where prior algorithms fail. 1.
Localization of the rhabdomyosarcoma t(2;13) breakpoint on a physical map of chromosome 13 (1991)

Previous investigations of the pediatric soft tissue tumor alveolar rhabdomyosarcoma have identified a characteristic translocation t(2;13)(q35;q14). We have employed a physical mapping strategy to localize the site of this translocation breakpoint on chromosome 13. Using a panel of somatic cell hybrid and lymphoblast cell lines with deletions and unbalanced translocations involving chromosome 13, we have mapped numerous probes from the 13q12-q14 region and demonstrate that this region is divisible into five physical intervals. These probes were then mapped with respect to the t(2;13) rhabdomyosarcoma breakpoint by quantitative Southern blot analysis of an alveolar rhabdomyosarcoma cell line with two copies of the derivative chromosome 13 and one copy of the derivative chromosome 2. Our findings demonstrate that the t(2;13) breakpoint is localized within a map interval delimited by the proximal deletion breakpoints in lymphoblast lines GM01484 and GM07312. Furthermore, the breakpoint is most closely flanked by loci D13S29 and TUBBP2 within this map interval. These findings will facilitate chromosomal walking strategies for cloning the regions disrupted by the alveolar rhabdomyosarcoma translocation. In addition, this physical map will permit rapid determination of the proximity of new cloned sequences to the translocation breakpoint.
Effect of Zinc Chloride or Lithium Chlorideon the Radical Polymerization of Acrylonitrile (1963)

非水系におけるアクリロニトリル(AN)のラジカル重合におよぼす塩化亜鉛(ZnCl2)ならびに塩化リチウム(LiCl)の効果について研究した。塊状でZnCl2はANのラジカル重合を加速したが,ジメチルホルムアミド(DMF)中では,加速効果はみとめられなかった。LiClの場合には逆に, 塊状では加速効果をしめさないが, D M F 中ではしめした。ZnCl2はANと容易に1:1のコンプレックスを形成し,単離することができたが,LiClの場合にはANとコンブレックスを形成しないので,両塩の作用機構はことなった理由にもとづくものと考えられた。ZnCl2の存在下におけるANの重合ではこのようなコンプレックス形成が極めて重要で,ZnCl2とコンプレックスを形成しないような塩化ビニリデン(VCl3)との共重合実験から,ZnCl2添加量と見掛けのANの反応性比,ならびにQ,e値が計算された。このようにして得られた見掛けのANのQ,e値とZnCl2濃度の関係を外挿して,1:1AN-ZnCl2コンプレックスのQ,e値としてQ=12.6,e=+8.2が得られた。LiClの場合にはANの反応性ならびにQ,e値は実験誤差内で変化しなかった。
Pharmacokinetics of recombinant human luteinizing hormone after intravenous, intramuscular, and subcutaneous administration in monkeys and comparison with intravenous administration of pituitary human luteinizing hormone. (1995)

To assess the pharmacokinetics of recombinant human LH (rhLH) in monkeys, we measured serum LH levels after single iv injection and after single and repeated doses by the im or sc route. A single iv bolus of 400 IU/kg rhLH or pituitary hLH (phLH) in six cynomolgus monkeys resulted in parallel concentration-time curves. The initial and terminal half-lives of rhLH (0.8 and 11 h) were comparable to those of phLH (0.6 and 10 h). The serum levels of phLH were consistently higher due to the fact that the immunological dose of phLH was higher. Administration of increasing iv doses of rhLH (10, 63, and 400 IU/kg) to six monkeys showed that the pharmacokinetics are linear over this dose range. The total clearance for the two higher doses was 0.03 L/h.kg. Systemic bioavailability was 50% after a single sc injection of 400 IU/kg and 61% after a single im injection of the same dose. The peak concentration (180 IU/L) after im injection was reached after 2.7 h. This was higher and sooner than after sc injection (110 IU/L after 5.3 h). The terminal half-life by both routes was similar to that seen after iv injection (11 h). Daily sc or im administration of 63 IU/kg for 7 days confirmed these findings. There was no accumulation of rhLH. Some monkeys developed antibodies, especially after repeated administration. They were excluded from the analysis. No significant local or systemic adverse events occurred.
Quantum Biometrics with Retinal Photon Counting (2017)

Nature has been working on single-photon technology for a lot longer than we have, so why not reap the benefits? Taking advantage of the well-studied capability of the human retina for single-photon detection, this project proposes ultrasecure biometric identification based on the perception of weak flashes of light. The authors turn the physics of photon statistics and the related detection by the eye into a quantum parameter-estimation problem, leading to a biometric quantifier. The security of this ``fingerprint'', based on subject-specific optical-loss parameters, can be understood and quantified---and guaranteed---by the physics of quantum measurement.
Mussel-inspired protein-repelling ambivalent block copolymers: controlled synthesis and characterization (2015)

Commentary Building the synovium: cadherin-11 mediates fibroblast-like synoviocyte cell-to-cell adhesion (2005)

Specific adhesion among like cells is a key determinant of the architecture of tissues. Homophilic (like binds like) adhesive interactions between cells are mediated by cadherins. These integral membrane glycoproteins have a crucial role in tissue morphogenesis during development and the maintenance of tissue integrity in adults. There is also an increasing recognition of a regulatory role for cadherins in a variety of cell functions, including cell migration. The recent identification of cadherin-11 expression in fibroblast-like synoviocytes (FLSs) has shed light on the mechanisms of synovial tissue organization and differentiation. Moreover, cadherin-11 expression in FLSs might also provide insight into pathways that determine the mesenchymal tissue response of the synovium to inflammation.
Intravenous curcumin efficacy on healing and scar formation in rabbit ear wounds under nonischemic, ischemic, and ischemia–reperfusion conditions (2014)

Curcumin, a spice found in turmeric, is widely used in alternative medicine for its purported anti-inflammatory and antioxidant activities. The goal of this study was to test the curcumin efficacy on rabbit ear wounds under nonischemic, ischemic, and ischemia-reperfusion conditions. Previously described models were utilized in 58 New Zealand White rabbits. Immediately before wounding, rabbits were given intravenous crude or pure curcumin (6 μg/kg, 30 μg/kg, or 60 μg/kg) dissolved in 1% ethanol. Specimens were collected at 7-8 days to evaluate the effects on wound healing and at 28 days to evaluate the effects on hypertrophic scarring. Student's t test was applied to screen difference between any treatment and control group, whereas analysis of variance was applied to further analyze for all treatment groups in aggregate in some specific experiments. Treatment with crude curcumin suggested accelerated wound healing that reached significance for reepithelialization in lower and medium doses and granulation tissue formation in lower dose. Purified curcumin became available and was used for all later experiments. Treatment with pure curcumin suggested accelerated wound healing that reached significance for reepithelialization in lower and medium doses and granulation tissue formation in lower dose. Treatment with pure curcumin significantly promoted nonischemic wound healing in a dose-response fashion compared with controls as judged by increased reepithelialization and granulation tissue formation. Improved wound healing was associated with significant decreases in pro-inflammatory cytokines interleukin (IL)-1 and IL-6 as well as the chemokine IL-8. Curcumin also significantly reduced hypertrophic scarring. The effects of curcumin were examined under conditions of impaired healing including ischemic and ischemia-reperfusion wound healing, and beneficial effects were also seen, although the dose response was less clear. Systemically administrated pure curcumin significantly promotes nonischemic wound healing and reduces hypertrophic scarring. Improvements in wound healing were associated with decreased inflammatory markers in wounds. Further study is needed to optimize dosing in ischemic and ischemia-reperfusion wound healing. In aggregate, the studies strongly support the systemic administration of curcumin to improve wound healing.

Totally ordered gigabit multicasting (1997)

Totally ordered multicast protocols are important in distributed system design, because totally ordered multicasts provide a considerably simpler programming paradigm than causally or unordered multicasts. These protocols convert the underlying unreliable and unordered message delivery provided by the network into high-quality reliable totally ordered message delivery. The emerging gigabit networks provide both ultra-high data rates and extremely low error rates. These characteristics strongly challenge the basic assumptions made for existing totally ordered multicast protocols. In this paper, we present the QuickRing multicast protocol, which provides totally ordered multicasting for the ring-based gigabit network QuickRing. The protocol is based on a buffer reservation strategy and uses timestamps both for buffer reservations and for total ordering of messages. Totally ordered multicasting implemented in hardware achieves low overhead, low latency, high throughput and low cost.
Detrusor Underactivity: Clinical Features and Pathogenesis of an Underdiagnosed Geriatric Condition (2006)

Urinary incontinence and other lower urinary tract symptoms exert a major influence on the health and independence of frail older people. Detrusor underactivity (DU) is defined as a contraction of reduced strength and/or duration, resulting in prolonged bladder emptying and/or a failure to achieve complete bladder emptying within a normal time span. DU may influence the clinical presentation and impede the therapy of disorders as common and as disparate as detrusor overactivity, urinary retention, and benign prostatic hyperplasia. Urodynamically, nearly two-thirds of incontinent nursing home residents exhibit DU. The clinical diagnosis of DU when present alone or in association with other bladder conditions such as detrusor overactivity (detrusor hyperactivity with impaired contractility (DHIC)) is challenging, because symptoms lack adequate precision. A catheterized and increasingly noninvasive ultrasound-based postvoid residual assessment allows a bedside diagnosis of retention and may suggest the presence of DU in individuals (mostly women) with a low likelihood of bladder outlet obstruction (BOO). Nevertheless, it cannot differentiate primary DU from retention secondary to BOO. The management of individuals with DHIC remains unsatisfactory, because antispasmodic anticholinergic medications may worsen retention, whereas bethanechol does not improve bladder emptying. Human detrusor biopsies reveal axonal degeneration, muscle loss, and fibrosis in DU. Animal studies suggest that multiple risk factors, including retention itself, lack of estrogen, infection, inflammation, and aging, may contribute to DU. Priority areas for future research include efforts to facilitate clinical nonurodynamic diagnosis of probable DU plus translational research designed to address the pathogenesis of this complex multifactorial geriatric syndrome.

Adenine Nucleosides in Solution: Stabilisation of the <i>anti</i>‐Conformation by C‐5′ Substituents (1974)

Proton magnetic resonance spectra of 30 adenine nucleosides have been obtained in dilute (0.001 to 0.05 M) aqueous or dimethyl sulfoxide solutions and have been analysed with respect to structure‐dependent variations of the purine proton chemical shifts. In 2 H 2 O the resonance signal of H‐8 shows a marked dependence upon the nature of substituents linked to C‐4′ of adenine ribofuranoside derivatives and upon the presence of a 2′: 3′‐ O ‐isopropylidene group while H‐2 is relatively unaffected. Therefore the chemical shift difference, δH‐8–δH‐2 =Δδ, may serve as an indicator of intramolecular ribose‐base interact ons. Δδ varies with the chemical nature of C‐4′ or C‐5′ substituents in the order: ammonium, sulfonium (0 ppm) < hydrogen < hydroxyl ∼ amino < thio < halogen < phosphate, carboxylate (0.4 ppm), and decreases with increasing chain length of these substituents. These results suggest the existence of electrostatic and dipolar repulsion or, in the majority of cases, attractive forces between the C‐5′ and C8‐H regions of adenine nucleosides which have been previously demonstrated for 5′‐nucleotides only. They imply a strong preference of most adenosine derivatives with unsubstituted 2′ and 3′‐hydroxyl groups for the anti ‐conformation range and the gauche, gauche C‐5′ conformation. In dimethyl sulfoxide, basically the same situation exists but different substituents exhibit smaller individual Δδ variations than in water, indicating different solvation shells. In this solvent two additional conformation‐stabilizing contributions can be recognized, viz. an interaction of the bridge oxygen (O‐4′) of ribose with adenine, and a hydrogen bond between H‐8 and a 5′‐carboxylate anion. This energetic stabilisation of the anti and g,g ‐conformers by most types of adenosine C‐5′ substituents supports the “rigidity” concept of nucleotides, extending it to the nucleoside level. The only exception found is 5′‐nitromethyladenosine in which ultraviolet, circular dichroism and magnetic resonance spectra suggest rotation of the adenine base to a “non‐classical” conformation due to base‐chain π‐electron interaction. The anti ‐conformation of the adenosine derivatives used in this study can in some cases be correlated with their enzymatic deamination by adenosine and AMP aminohydrolase.
Ionic Conductivity of Solid and Liquid LiAlCl4 (1977)

The electrical conductivity of lithium chloroaluminate has been investigated in the temperature range between room temperature and 180°C. It is molten above 145°C. The conduction is practically purely ionic and is attributed to the transport of lithium ions. The experiments show high values for ionic conductivity in the solid state, only exceeded by Li‐β‐alumina and some LiI‐based materials. At 25°C the conductivity was found to be , with an activation enthalpy for of 0.47 eV. A‐C conductivity measurements were influenced by sample preparation and cell arrangement. The ionic conductivities of this and several other newly found lithium ionic conductors, as well as those previously known, are compared in the temperature range between 20° and 250°C.
Mononuclear cell infiltration in central portions of human astrocytomas (1988)

The mononuclear cell infiltration in the central portion of human low- and high-grade astrocytomas has been examined using monoclonal antibodies to cell surface differentiation antigens. There was no significant difference between the number of T cells, B cells, or macrophages. The OKT8+ (suppressor/cytotoxic) T cell population was the major lymphocyte subset in the infiltrates. There was, however, indirect evidence for a proportion of the total OKT8+ cells being natural killer cells. Overall, there was a significant difference in the number of macrophages compared to the total lymphoid cell population. Several cell types seem to play an equal role in the cellular and humoral immune response within the center of the tumors, as distinct from that occurring at the periphery.
Synthesis of 1H-imidazoles by the simple ring transformation of 5-acylaminouracils and 5-acylaminopyrimidin-4(3H)-ones (1991)

1,2-Disubstituted 4-alkylcarbamoyl-5-methyl-1H-imidazoles and 2-substituted 5-methyl-4-phenylcarbamoyl-1H-imidazoles were synthesized from 5-acylamino-6-methyluracils and 5-acylamino-6-methyl-3-phenylpyrimidin-4(3H)ones by treatment with sodium hydroxide in ethanol. In the case of 5-acylaminopyrimidinones which possess an olefinic group in the acylamino group, 2-ethoxyethyl (or 2-ethoxypropyl)-5-methyl-4-phenylcarbamoyl-1H-imidazoles were prepared as major products and the corresponding 2-alkenyl-1H-imidazoles were only minor products. Compounds which contain an aryl function in their acylamino group gave glycine anilides as by products.
Protection of audio amplifiers based on temperature measurements in power transistors (2004)

An audio amplifier IC has been realized with protection circuitry based directly upon power-transistor temperature measurements. In contrast to current- or voltage-based measurements, this method gives optimal protection independent of supply voltage (9-28V), load (2-16/spl Omega/ BTL), ambient temperature and heat sinking.
Accuracy of stroke volume variation compared with pleth variability index to predict fluid responsiveness in mechanically ventilated patients undergoing major surgery (2010)

Although arterial pressure-derived SVV revealed the best correlation to volume-induced changes in SVI, the results of our study suggest that both variables, SVV and PVI, can serve as valid indicators of fluid responsiveness in mechanically ventilated patients undergoing major surgery.
Wideband beam patterns from sparse arrays (1990)

Transient radiated fields due to impulsively excited apertures and aperture response due to incident impulsive waves has been the subject of considerable research in acoustics over the last decade. This research is also of importance to wideband radar. Medical ultrasound steered phased arrays use transmitted pulses consisting of from 1 to 3 cycles of a damped sinusoid, which is similar to certain radar systems. As will be shown, planar arrays using ultra-wide band pulses may be formed with very sparsely spaced elements. This makes feasible very high resolution, economical, and relatively simple, steered beam phased arrays. The resolution may be increased simply by moving the array elements further apart. Grating lobes due to aliasing are not formed when the elements are sparsely spaced. In a very sparse wide band array, element spacing effects the form, or signal shape in time, rather than the peak amplitude of the sidelobe structure. The number of elements in the aperture determines the peak sidelobe level which, in theory, may be decreased without limit. 13 refs., 7 figs.

Reaction of 2,2-dimethyl-1,3-dioxin-4-ones with imines, carbodiimides, and isocyanates. (1984)

The ring transformation of 2, 2-dimethyl-1, 3-dioxin-4-ones (1) to nitrogen heterocycles was studied. Heating of 1 with imines such as Schiff bases gave rise to [2+4] cycloadducts of imines to acylketenes (2), i.e., 3, 4-dihydro-1, 3-oxazin-4-one derivatives (4). Similarly, 1 reacted with carbodiimides to yield 2-imino-1, 3-oxazin-4-one derivatives (11 and 12). The reaction of 1 with phenyl isocyanate gave 3-phenyl-1, 3-oxazine-2, 4-diones (15), while the reaction with 2-pyridyl isocyanate gave pyrido [1, 2-a] pyrimidin-4-one derivatives (18).
