A unique cytoskeleton associated with crawling in the amoeboid sperm of the nematode, Ascaris suum. (1989)

Nematode sperm extend pseudopods and pull themselves over substrates. They lack an axoneme or the actin and myosins of other types of motile cells, but their pseudopods contain abundant major sperm protein (MSP), a family of 14-kD polypeptides found exclusively in male gametes. Using high voltage electron microscopy, a unique cytoskeleton was discovered in the pseudopod of in vitro-activated, crawling sperm of the pig intestinal nematode Ascaris suum. It consists of 5-10-nm fuzzy fibers organized into 150-250-nm-thick fiber complexes, which connect to each of the moving pseudopodial membrane projections, villipodia, which in turn make contact with the substrate. Individual fibers in a complex splay out radially from its axis in all directions. The centripetal ends intercalate with fibers from other complexes or terminate in a thickened layer just beneath the pseudopod membrane. Monoclonal antibodies directed against MSP heavily label the fiber complexes as well as individual pseudopodial filaments throughout their length. This represents the first evidence that MSP may be the major filament protein in the Ascaris sperm cytoskeleton. The large fiber complexes can be seen clearly in the pseudopods of live, crawling sperm by computer-enhanced video, differential-interference contrast microscopy, forming with the villipodia at the leading edge of the sperm pseudopod. Even before the pseudopod attaches, the entire cytoskeleton and villipodia move continuously rearwards in unison toward the cell body. During crawling, complexes and villipodia in the pseudopod recede at the same speed as the spermatozoon moves forward, both disappearing at the pseudopod-cell body junction. Sections at this region of high membrane turnover reveal a band of densely packed smooth vesicles with round and tubular profiles, some of which are associated with the pseudopod plasma membrane. The exceptional anatomy, biochemistry, and phenomenology of Ascaris sperm locomotion permit direct study of the involvement of the cytoskeleton in amoeboid motility.
Worldly Vagueness and Semantic Indeterminacy (2008)

Abstract This chapter continues the examination begun in the previous chapter of objections to the fuzzy view of vagueness in particular, and to degree theoretic treatments of vagueness in general. It covers the major remaining objections to the fuzzy view: the problems of artificial precision and sharp boundaries. In response, a new version of the fuzzy view is proposed, called fuzzy plurivaluationism, which combines fuzzy models with semantic indeterminacy of the sort involved in plurivaluationism. The chapter concludes that fuzzy plurivaluationism is the correct theory of vagueness, on the grounds that, first, it is a degree theory — and so satisfies the positive requirement on a theory of vagueness — and, second, it withstands all known objections to degree theories.

High speed positioning servo system using integrator correction of PI controller based on disturbance observer (2008)

An ideal positioning servo system should accelerate the rotor of servo motor by its maximum acceleration torque and stop at the target position without overshoot. When the positioning servo system has no ideal profile of position reference, the conventional positioning servo system cannot realize the ideal high speed positioning response. In order to overcome this problem without the ideal profile of position control, this paper proposes a new high speed positioning servo system using integrator correction of PI controller based on disturbance observer. The proposal method corrects the integrator value of its minor PI speed regulator by using the torque current reference estimated by disturbance observer. The experimental results confirm that the proposed high speed positioning servo system attains the fine and smooth high speed positioning response with the shortest settling time.
Towards the Factory of the Future: A Service-oriented Cross-layer Infrastructure (2009)

The business world is highly competitive, and in order to successfully tackle everyday chal-lenges operational managers and executives demand high dependability and wide visibility into the status of their business process networks. The latest is done usually via business key performance indicators (KPIs). However, in order to provide up-to-date information and be able to react in a ﬂ exible and optimal way to changing conditions, real-time information must ﬂ ow via all layers from the shop ﬂ oor up to the business process level. In that sense enterprises are moving towards service-oriented infrastructures that bring us one step closer to the vision of real-time enterprises. Applications and business processes are modelled on top of and using an institution-wide or even cross-institutional service landscape. For any solution to be easily integrated in this environment, it must feature a service-based approach.Currently, shop-ﬂ oor intelligent systems based on distributed embedded devices concentrate the programming of the behaviour and intelligence on a handful of large monolithic comput-ing resources accompanied by large numbers of dumb devices. The intelligence and behaviour are tailored and individually programmed for each application. However, as we are moving towards the ‘Internet of Things’ [6], where millions of devices will be interconnected, provide and consume information available on the network and co-operate, new capabilities as well as challenges come into play. As these devices need to inter-operate, the service-oriented approach seems a promising solution, i.e. each device offers its functionality as a service, while in parallel it is possible for it to discover and invoke new functionality from other services on demand [8]. By considering the set of intelligent system units as a conglomerate of distributed, autonomous, intelligent, pro-active, fault-tolerant and reusable units, which operate as a set of co-operating
Phonon amplification using evaporation and adsorption of helium (1996)

We report the results of experiments designed to investigate the feasibility of amplifying a phonon signal using the evaporation of helium from a superfluid film and its subsequent readsorption onto a helium-free surface. We envision a multistage amplifier in which helium is evaporated from a wafer with a helium film only on one side and then adsorbed onto the film-free surface of a similar wafer. The phonons created by the adsorption reach the film on the opposite side of the wafer and potentially desorb more helium than was evaporated by the first wafer. The amplification would come from the high ratio of the binding energy of a helium atom to a film-free surface relative to the binding energy to the liquid. A number of experiments are reported that investigate the efficiencies of the individual steps of the process. The gain per stage is found to be about 3 for high-energy densities in which multiphonon processes are possible. At low-energy densities, the energy deposited into a film-free wafer is found to be less than the original input energy, with the ratio of output to input energy 0.2. Since in applications requiring amplification the phonon density produced by the adsorption of helium on a wafer will be low, the configuration we have studied---phonons produced in silicon coated with a saturated $^{4}\mathrm{He}$ film---will not result in amplification. However, other configurations might improve the efficiency enough to make an amplifier possible. \textcopyright{} 1996 The American Physical Society.
Experimental study of small-signal gain and laser beam parameters in high-power pulse-repetitive rf-excited slab CO 2 lasers (2001)

The paper presents the results of measuring of the small-signal gain <g0> in the active medium of the high-power pulserepetitive RF-excited slab C02-laser. The measurements were carried out for the pumping pulse durations in the range 20.50 Ls and pulse repetition rates 100.500 Hz. The maximal specific energy, delivered to the active medium, was 430 W/cm3. In the experiment were measured the average output power of radiation, pulse energy and power and the output beam divergence.

Combined frequency and time domain measurements on injection-locked, constriction-based spin Hall nano-oscillators (2019)

We demonstrate a combined frequency and time domain investigation of injection-locked, constriction-based spin Hall nano-oscillators by Brillouin light scattering (BLS) and the time-resolved magneto-optical Kerr effect (TR-MOKE). This was achieved by applying an ac current in the GHz regime in addition to the dc current which drives auto-oscillations in the constriction. In the frequency domain, we analyze the width of the locking range, the increase in intensity, and the reduction in the linewidth as a function of the applied direct current. Then, we show that the injection locking of the auto-oscillation allows for its investigation by TR-MOKE measurements, a stroboscopic technique that relies on a phase stable excitation, in this case given by the synchronisation to the microwave current. Field sweeps at different dc currents clearly demonstrate the impact of the spin current on the Kerr amplitude. Two-dimensional TR-MOKE and BLS maps show a strong localization of the auto-oscillation within the constriction, independent of the external locking.

Elevated Foot Diffusion and Resting Perfusion in Patients with Diabetic Foot Ulcer: A Pilot and Feasibility Study (2023)

Here we apply intravoxel incoherent motion (IVIM) and fractional Fickian diffusion (FFD) models to multi-b-value diffusion-weighted-MRI to study tissue cellular and resting microvascular properties of the foot of patients with diabetic foot ulcer. We report preliminary results from an ongoing study comparing patients with type 2 diabetes and persistent plantar foot ulcers with healthy age- and BMI-matched individuals. Pseudo-diffusion and mean diffusion coefficients and microvascular volume fraction were elevated in patients, showing large effect sizes in subregions. This approach may prove useful for evaluating patients with ulcers to prognosticate tissue at risk of poor wound healing.

Pass transistor designs using pocket implant to improve manufacturability for 256 Mbit DRAM and beyond (2002)

Pass transistor designs for scaled 256 Mbit DRAM are studied in this paper. It is shown, for the first time, that a L/sub g/=0.25 /spl mu/m and t/sub ox/=85 /spl Aring/ transistor utilizing a pocket implant together with a light V/sub TN/ implant (pocket-with-V/sub TN/) can satisfy the stringent requirements of subthreshold leakage, diode leakage, V/sub T/ during charging, and a tolerance for L/sub g/ variation of 0.08 /spl mu/m for manufacturability. The success of the pocket-implant device in meeting the above design spec is due to the reduced V/sub T/ roll-off at shorter L/sub g/ and reduced body effect at longer L/sub g/ compared to those of a conventional device. An optimum range of substrate bias is determined to be -1.5 to -2 V. It is also shown that the pocket implant does not degrade the gate oxide integrity nor channel hot-electron reliability.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
CORTICAL VOLUME MEASUREMENT IN UNCEMENTED TOTAL HIP REPLACEMENTS- A CT BASED ANALYSIS (2009)

Periprosthetic bone remodeling after uncemented hip replacement has always been a matter of research and debate. DEXA analysis of bone density was studied by previous groups but not the cross sectional cortical volume. We report a validated CT based algorithm for accurate measurement of cortical volume in these group of patients. Twenty two patients who have undergone Uncemented Furlong total hip replacement agreed to undergo CT scan of their hips for our study. The mean age was 74.6 yrs. The mean follow up was 5.4 yrs. Using software adapted for the specific purpose, femoral cortical volume was measured at three different levels at a fixed distance from the lower border of the lesser trochanter on both sides: 6mm distal to the tip of the prosthesis (z), At the top of the cylindrical portion(x) Midway between x and z (y). Accuracy of the method was assessed by measuring the volume of artificial cavities created on a polyurethane pelvis. Assessment of precision of method was done by calculating the level of agreement between two observers. The mean cortical volume in the proximal cylindrical portion (x), midpoint(y) and the portion of bone distal to the prosthesis (z) were 458 mm3, 466 mm3, 504 mm3 respectively. The corresponding cortical volumes in the contralateral native femur in unilateral hip replacements were 530 mm3(x), 511 mm3(y), 522 mm3 (z) giving a ratios of 0.86(x), 0.91(y) and 0.97(z). The mean cortical volumes on the left side of bilateral hips were 490 mm3(x), 499 mm3(y) and 528 mm3 (z). The mean cortical volumes on the right side were 456 mm3(x), 463 mm3 (y) and 516 mm3 (z). No significant trend was noted with change of volume of bone with time. In the three cases who had cemented hips on their other side, the cemented hips exhibited substantially more stress shielding than their cementless controls (ratios of 0.82, 0.74 and 0.85). A high correlation between the test and standard measurements was noted. The interobserver agreement between two observers was also good. In a fully coated uncemented femoral component, with documented long term results, it is to be expected that load will be shed steadily along the length of the prosthesis. In this study we have confirmed this supposition, with volumetric data, by showing that an almost normal bone just below the tip of the stem (97% volume) reduces to a bone volume of 91% by the middle of the stem and then 86% by the shoulder of the prosthesis. This decrease in the volume of cortical bone effectively normal at the tip of the prosthesis while not optimal appears to stabilize early with no trend of continued reduction over a decade. The effect of cementation on stress shielding was only examined incidentally in this study but appears to contribute to more marked bone loss.
Grand Challenges for Global Brain Sciences (2016)

The next grand challenges for society and science are in the brain sciences. A collection of 60+ scientists from around the world, together with 10+ observers from national, private, and foundations, spent two days together discussing the top challenges that we could solve as a global community in the next decade. We eventually settled on three challenges, spanning anatomy, physiology, and medicine. Addressing all three challenges requires novel computational infrastructure. The group proposed the advent of The International Brain Station (TIBS), to address these challenges, and launch brain sciences to the next level of understanding.
Data from Alarmin IL-33 Acts as an Immunoadjuvant to Enhance Antigen-Specific Tumor Immunity (2023)

&lt;div&gt;Abstract&lt;p&gt;Studies of interleukin (IL)-33 reveal a number of pleiotropic properties. Here, we report that IL-33 has immunoadjuvant effects in a human papilloma virus (HPV)–associated model for cancer immunotherapy where cell-mediated immunity is critical for protection. Two biologically active isoforms of IL-33 exist that are full-length or mature, but the ability of either isoform to function as a vaccine adjuvant that influences CD4 T helper 1 or CD8 T-cell immune responses is not defined. We showed that both IL-33 isoforms are capable of enhancing potent antigen-specific effector and memory T-cell immunity &lt;i&gt;in vivo&lt;/i&gt; in a DNA vaccine setting. In addition, although both IL-33 isoforms drove robust IFN-γ responses, neither elevated secretion of IL-4 or immunoglobulin E levels. Further, both isoforms augmented vaccine-induced antigen-specific polyfunctional CD4&lt;sup&gt;+&lt;/sup&gt; and CD8&lt;sup&gt;+&lt;/sup&gt; T-cell responses, with a large proportion of CD8&lt;sup&gt;+&lt;/sup&gt; T cells undergoing plurifunctional cytolytic degranulation. Therapeutic studies indicated that vaccination with either IL-33 isoform in conjunction with an HPV DNA vaccine caused rapid and complete regressions &lt;i&gt;in vivo&lt;/i&gt;. Moreover, IL-33 could expand the magnitude of antigen-specific CD8&lt;sup&gt;+&lt;/sup&gt; T-cell responses and elicit effector–memory CD8&lt;sup&gt;+&lt;/sup&gt; T cells. Taken together, our results support the development of these IL-33 isoforms as immunoadjuvants in vaccinations against pathogens, including in the context of antitumor immunotherapy. &lt;i&gt;Cancer Res; 74(6); 1789–800. ©2014 AACR&lt;/i&gt;.&lt;/p&gt;&lt;/div&gt;
Λ[sup 0] Polarization in pp→pΛ[sup 0]K[sup +] at 800 GeV∕c (2008)

We determined Λ0 polarization as function of XF, PT, MX, and EΛ, with respect to the normal of the following two different production planes: The first one defined by the momentum of the 800 GeV/c proton beam and the moment of Λ0; the second one, by the momentum of the transferred object and the momentum of Λ0, from the sample created in the FNAL E690 experiment. We present results, compare and discuss them.
PMIPv6 multicast handover optimization by the Subscription Information Acquisition through the LMA (SIAL) (2012)

This document specifies a multicast handover optimization mechanism
for Proxy Mobile IPv6 to accelerate the delivery of multicast traffic
to mobile nodes after handovers. The mechanism is based on speeding up
the acquisition of mobile nodes' multicast context by the mobile
access gateways. To do that, extensions to the current Proxy Mobile
IPv6 protocol are proposed. These extensions are not only applicable
to the base solution for multicast support in Proxy Mobile IPv6, but
they can also be applied to other solutions being developed to avoid
the tunnel convergence problem. Furthermore, they are also independent
of the role played by the mobile access gateway within the multicast
network (either acting as multicast listener discovery proxy or
multicast router).
LPR Sensor Made by Using Ordered Porous Alumina (2009)

We fabricated a LPR (Localized Plasmon Resonance) sensor using ordered porous alumina. The fabricated nanostructure is very uniform and can be made using a simple process. These devices exhibit unique optical properties due to interactions between LPR and a thin film resonator. Finally, we demonstrate that this device can be applied to a biosensor using its LPR characteristics.
Direct analysis of cellular proteins by capillary electrophoresis FTICR MS (1995)

Direct chemical analysis of living cells has received considerable attention in recent years; the single cell approach provides a major step towards answering important questions in the field of cellular biochemistry. In this work, the authors present preliminary results which demonstrate the feasibility of using the CE-ESI-FTICR combination as a high performance detection scheme for the analysis of cellular proteins acquired directly from small populations of intact living cells. The human erythrocyte (red blood cell) was chosen as a model system owing to its availability, relatively homogeneous composition, and thorough documentation of contents by previous researchers. The contents of the erythrocyte are unusually homogeneous; nearly the entire volume of the cell is filled with hemoglobin, approximately 450 amol per cell, a challenging but attainable level for mass spectrometric detection with current instrumentation. In this work, the authors demonstrate the on-line acquisition of high resolution mass spectra (average resolution {ge} 45,000 FWHM) of the {alpha} and {Beta} hemoglobin chains acquired from the injection of as few as 10 human erythrocytes (this corresponds to {approx} 4.5 fmol of hemoglobin). Additionally, when used in conjunction with quadrupolar axialization and sustained off-resonance irradiation, it is possible to directly obtain partial sequence information of selectedmore » cellular components obviating the need for additional isolation/purification steps. Given the extremely small volume of the human erythrocyte (typically {approx} 87 fL/cell), the authors are optimistic that the techniques implemented here will be adaptable to the study of many larger mammalian cell systems.« less
