Effect of rinse with calcium enriched milk on plaque fluid. (1999)

Previous research has shown that rinsing the mouth with milk significantly diminished the pH in dental plaque fluid; however, the degree of saturation with respect to the dental enamel (DS) was not significantly decreased because of an increase in the calcium ion concentration in plaque fluid. The aim of this study was to investigate the cariostatic effect of adding calcium to milk on the DS value of the plaque fluid after rinsing. Plaque samples were collected from 8 Japanese male dental students. Prior to plaque collection, all subjects refrained from practicing oral hygiene for 48 hr and fasted overnight. Supragingival plaque samples were collected from one side of the mouth of each subject, and then collected from the other side, following a 30-second rinse with 15 mL of calcium-enriched milk, which was prepared by adding calcium carbonate to ordinary milk, and a 10-minute waiting period. The samples were cleared by centrifugation, and the plaque fluid was analyzed for inorganic ions and pH, using an ion chromatograph and pH microelectrode, respectively. The calcium ion concentration of the milk was 6.4 mM, which was about 36% higher than that of ordinary milk. The pH decreased significantly (p<5%) from 6.4 to 6.1 following the rinse with calcium enriched milk, as tested by the paired t-test. The decrease in pH might have caused a reduction of the DS value; however, it was compensated for by a significant (p<0.5%) increase in the calcium ion concentration of plaque fluid.

F-6-4-1 Vibration Control of Cantilever Beams Moving Along the Axial Direction (2002)

In this paper a vibration control technique is proposed for flexible body moving along the axial direction such as the plates or the wire rods in the mill, and the effect is verified by numerical simulation. The dynamic characteristics of the cantilever beam moving along the axial direction are examined by using the Lagrange's equation of motion. It is shown that the vibration of the cantilever beam moving along the axial direction is caused by self-excited vibration, and that optimal damper-spring properties at the beam support point are obtained by examining the stability of a simple vibration model.
Scale‐aware Structure‐Preserving Texture Filtering (2016)

Abstract This paper presents a novel method to enhance the performance of structure‐preserving image and texture filtering. With conventional edge‐aware filters, it is often challenging to handle images of high complexity where features of multiple scales coexist. In particular, it is not always easy to find the right balance between removing unimportant details and protecting important features when they come in multiple sizes, shapes, and contrasts. Unlike previous approaches, we address this issue from the perspective of adaptive kernel scales. Relying on patch‐based statistics, our method identifies texture from structure and also finds an optimal per‐pixel smoothing scale. We show that the proposed mechanism helps achieve enhanced image/texture filtering performance in terms of protecting the prominent geometric structures in the image, such as edges and corners, and keeping them sharp even after significant smoothing of the original signal.

Latent-transforming growth factor beta-binding protein-2 (LTBP-2) is required for longevity but not for development of zonular fibers (2020)

Latent-transforming growth factor beta-binding protein 2 (LTBP-2) is a major component of arterial and lung tissue and of the ciliary zonule, the system of extracellular fibers that centers and suspends the lens in the eye. LTBP-2 has been implicated previously in the development of extracellular microfibrils, although its exact role remains unclear. Here, we analyzed the three-dimensional structure of the ciliary zonule in wild type mice and used a knockout model to test the contribution of LTBP-2 to zonule structure and mechanical properties. In wild types, zonular fibers had diameters of 0.5-1.0 micrometers, with an outer layer of fibrillin-1-rich microfibrils and a core of fibrillin-2-rich microfibrils. LTBP-2 was present in both layers. The absence of LTBP-2 did not affect the number of fibers, their diameters, nor their coaxial organization. However, by two months of age, LTBP-2-depleted fibers began to rupture, and by six months, a fully penetrant ectopia lentis phenotype was present, as confirmed by in vivo imaging. To determine whether the seemingly normal fibers of young mice were compromised mechanically, we compared zonule stress/strain relationships of wild type and LTBP-2-deficient mice and developed a quasi-linear viscoelastic engineering model to analyze the resulting data. In the absence of LTBP-2, the ultimate tensile strength of the zonule was reduced by about 50%, and the viscoelastic behavior of the fibers was altered significantly. We developed a harmonic oscillator model to calculate the forces generated during saccadic eye movement. Model simulations suggested that mutant fibers are prone to failure during rapid rotation of the eyeball. Together, these data indicate that LTBP-2 is necessary for the strength and longevity of zonular fibers, but not necessarily for their formation.
Geometric numerical integration illustrated by the Störmer–Verlet method (2003)

The subject of geometric numerical integration deals with numerical integrators that preserve geometric properties of the flow of a differential equation, and it explains how structure preservation leads to improved long-time behaviour. This article illustrates concepts and results of geometric numerical integration on the important example of the Störmer–Verlet method. It thus presents a cross-section of the recent monograph by the authors, enriched by some additional material. After an introduction to the Newton–Störmer–Verlet–leapfrog method and its various interpretations, there follows a discussion of geometric properties: reversibility, symplecticity, volume preservation, and conservation of first integrals. The extension to Hamiltonian systems on manifolds is also described. The theoretical foundation relies on a backward error analysis, which translates the geometric properties of the method into the structure of a modified differential equation, whose flow is nearly identical to the numerical method. Combined with results from perturbation theory, this explains the excellent long-time behaviour of the method: long-time energy conservation, linear error growth and preservation of invariant tori in near-integrable systems, a discrete virial theorem, and preservation of adiabatic invariants.

In vitro translocation of bacterial proteins across the plasma membrane of Escherichia coli. (1984)

Precursors to two periplasmic proteins and one outer membrane protein were synthesized in a membrane-free extract from Escherichia coli programmed with plasmid DNA. In the presence of inverted plasma membrane vesicles from E. coli up to 25% of the precursor molecules were converted into their mature forms. Using externally added proteinase K as a probe, we found the processed proteins segregated within the membrane vesicles. By the same criteria, a small amount of each precursor also proved to be translocated, indicating that translocation and signal sequence cleavage are not necessarily coupled processes. Furthermore, we present conclusive evidence that the translocation step can occur post-translationally even as late as 60 min after the beginning of translation.
<title>Left ventricle wall motion tracking using curvature properties</title> (1992)

This paper presents the complete implementation of the new algorithm for tracking points on the left ventricle (LV) surface from volumetric cardiac images. We define the local surface stretching as an additional motion parameter of nonrigid transformation. Stretching is constant at all points on the surface for homothetic motion, or follows a polynomial function of certain order (linear in our implementation) in conformal motion. The wall deformation and correspondence information between successive frames of LV in a heart cycle are considered important in evaluating heart behavior and improved diagnosis. We utilize small motion assumption between consecutive frames, hypothesize all possible correspondences, and compute curvature changes for each hypothesis. The computed curvature change is then compared with the one predicted by conformal motion assumption for hypotheses evaluation. We demonstrate the improved performance of the new algorithm utilizing conformal motion with linear stretching assumption over constant stretching assumption on simulated data. Then, the algorithm is applied to real cardiac (CT) images and the stretching of the LV wall is determined. The data set used in our experiments was provided by Dr. Eric Hoffman at University of Pennsylvania Medical school and consists of 16 volumetric (128 by 128 by 118) images taken through the heart cycle.
ZRANB2 and SYF2-mediated splicing programs converging on ECT2 are involved in breast cancer cell resistance to doxorubicin (2019)

Besides analyses of specific alternative splicing (AS) variants, little is known about AS regulatory pathways and programs involved in anticancer drug resistance. Doxorubicin is widely used in breast cancer chemotherapy. Here, we identified 1723 AS events and 41 splicing factors regulated in a breast cancer cell model of acquired resistance to doxorubicin. An RNAi screen on splicing factors identified the little studied ZRANB2 and SYF2, whose depletion partially reversed doxorubicin resistance. By RNAi and RNA-seq in resistant cells, we found that the AS programs controlled by ZRANB2 and SYF2 were enriched in resistance-associated AS events, and converged on the ECT2 splice variant including exon 5 (ECT2-Ex5+). Both ZRANB2 and SYF2 were found associated with ECT2 pre-messenger RNA, and ECT2-Ex5+ isoform depletion reduced doxorubicin resistance. Following doxorubicin treatment, resistant cells accumulated in S phase, which partially depended on ZRANB2, SYF2 and the ECT2-Ex5+ isoform. Finally, doxorubicin combination with an oligonucleotide inhibiting ECT2-Ex5 inclusion reduced doxorubicin-resistant tumor growth in mouse xenografts, and high ECT2-Ex5 inclusion levels were associated with bad prognosis in breast cancer treated with chemotherapy. Altogether, our data identify AS programs controlled by ZRANB2 and SYF2 and converging on ECT2, that participate to breast cancer cell resistance to doxorubicin.
New Insights on the Role of Multivalent Ions in Water-Carbonate Rock Interactions (2014)

Abstract The current study is focused on the effects of the individual key ions (Ca2+, Mg2+, (SO4)2-) along with a few of other common ions (Na+ and Cl-) on carbonate rock by only injecting water with controlled amount of individual or combined ions into the selected carbonate rock at reservoir temperature. A low field NMR technique has been a tool of choice for the current work since it allows monitoring the physical and chemical alteration of rock surface after interacting with fluids which contain specific types and amount of ions. In addition, since NMR is non-destructive measurement, the effect of various types of fluids with the identical rock sample before, during, and after core flooding test can be monitored repeatedly. NMR results indicate that the water-rock interaction changes when injecting different types of ions. The interaction a of key divalent key ions, Ca2+, Mg2+, and (SO4)2-, on the carbonate rock surface are observed with relatively weak reactivity of Ca2+ compare to the other two. At the reservoir temperature, 90°C, the reactivity of Mg2+ with the carbonate rock is greater than that of Ca2+. The reactivity of multivalent anion (SO4)2- is also significant with carbonate rock surface, but it will induce surprising behavior on NMR response. The fundamental understandings acquired by the current study, effects of key ions in carbonate rock with single-phase fluid will be one of the key building blocks to develop rigid understanding of more complicated multi-phase fluid interaction with various types of reservoir rocks, and eventually draw conclusions on how these ions change rock wettability.
Complex wattmeter measurements in a reactive acoustic field (1979)

A wattmeter is described which is capable of measuring separately the real and imaginary parts of the complex acoustic intensity in water. A general expression for the complex intensity is derived and used to provide a basis for the experimental measurements. The instrument was tested for the case of a point source. The results show the real part of the intensity to decrease as 1/r2 from the source and the imaginary to decrease as 1/r3 as predicted by the theory.
Energy Efficient Capacitive Body Channel Access Schemes for Internet of Bodies (2021)

The Internet of bodies is a network of wearable, ingestible, injectable, and implantable smart objects located in, on, and around the body. Although radio frequency (RF) systems are considered the default choice for implementing on-body communications, which need to be localized in the vicinity of the human body (typically < 5 cm), highly radiative RF propagations unnecessarily extend several meters beyond the human body. This intuitively degrades energy efficiency, leads to interference and co-existence issues, and exposes sensitive personal data to security threats. As an alternative, the capacitive body channel communication (BCC) couples the signal (between 10 kHz-100 MHz) to the human body, which is more conductive than air. Hence, BCC provides a lower propagation loss, better physical layer security, and nJ/bit to pJ/bit energy efficiency. Accordingly, this paper investigates orthogonal and non-orthogonal capacitive body channel access schemes for ultra-low-power IoB nodes. We present the optimal uplink and downlink power allocations in closed-form, which deliver better fairness and network lifetime than benchmark numerical solvers. For a given bandwidth and data rate requirement, we also derive the maximum affordable number of IoB nodes for both directions of orthogonal and non-orthogonal schemes.

Insertion of Calcium Ion into Prussian Blue Analogue in Nonaqueous Solutions and Its Application to a Rechargeable Battery with Dual Carriers (2015)

We observed the first electrochemical insertion of Ca2+ into Prussian blue analogue, MnFe(CN)6, in nonaqueous solutions of Ca(CF3SO3)2 and various solvents including ionic liquid at 60 °C. The kinetics for the Ca2+ insertion reaction were studied by cyclic voltammetry, and were compared to those of Na+ intercalation. By coupling this phenomenon with metallic anodes, two energy storage devices were made. Ca anode produced a primary cell that operated at a voltage of around 2.0 V. When Mg plate was used as an anode, the negative active material associated with CF3SO3–, which we have already reported was newly formed at the surface of Mg plate. By combining the negative active material, we have fabricated a novel rechargeable battery using dual ion transport species of Ca2+ for the cathode and CF3SO3– for the anode, and demonstrated that the battery showed repeated discharge/charge performance.
Conjecture on the True Cause and Meaning of Time Dilation (2012)

The fundamental forces of nature are mediated by the exchange of particles; photons mediate the electromagnetic force, gluons the strong force, W and Z particles the weak force. It is shown that the duration of the exchange of a force or messenger particle between two interacting particles is a function of the velocity through space of the two interacting particles and is also a function of the orientation of the two particles relative to their common velocity. The greater the velocity of the two particles the longer it takes for the particle exchange between them. The interaction between two particles is thus slowed by their motion through space. This slowing with velocity of the interaction between particles underlies the fundamental process occurring in any physical entity (proton, nucleus, atom, or macro object). It is the essence of time dilation. The dependence of time dilation on the orientation of two interacting particles relative to their common velocity is an important finding of this study and may appear to contradict the ‘known’ singular dependence of time dilation on velocity. The dependence of time dilation on the orientation of the interacting particles is overcome when a large number of particles are aggregated and their orientations relative to the velocity of the aggregate body or entity are randomized. Alternatively, the rapidly changing orientation of two particles in the turbulence of space will itself randomize the orientation of the particles and cause the value of time dilation of the particles to ‘average out’. We can look at time dilation in two ways; 1) time actually slows for the fast moving entity or 2) the basic process that governs the entity takes longer as the entity moves through space, but time itself does not slow down. This may be more a philosophical question than a scientific one. The momentum of current thought is clearly with time slowing down for the moving entity. The conclusion of this paper is that time dilation is a slowing of the fundamental process of an entity when the entity is moving through space, not a slowing of time itself.
