Specificities and Kinetics of Uracil Excision from Uracil-Containing DNA Oligomers by Escherichia coli Uracil DNA Glycosylaset (1991)

Uracil DNA glycosylase excises uracil residues from DNA that can arise as a result of deamination of cytosine or incorporation of dUMP residues by DNA polymerase. We have carried out a detailed study to define the specificities and the kinetic parameters for its substrates by using a number of synthetic oligodeoxyribonucleotides of varying lengths and containing uracil residue(s) in various locations. The results show that the Escherichia coli enzyme can remove a 5'-terminal U from an oligomer only if the 5'-end is phosphorylated. The enzyme does not remove U residues from a 3'-terminal position, but U residues can be excised from oligonucleotides with either pd(UN)p or pd(UNN) 3'-termini. The oligomer d(UUUUT) can have the second or third U residues from the 5'-end excised even when the neighboring site is an abasic site (3' or 5', respectively). On the basis of these findings, pd(UN)p was anticipated to be the smallest size substrate. Results show detectable amounts of U release from the substrate pd(UT)p; however, significantly higher amounts of U release were observed from pd(UT-sugar) or pd(UTT). Determinations of the K, and V,,, values show that the different rates of U excision from oligomers of different sizes (trimeric to pentameric) but containing U in the same position are largely due to the differences in the K, values, whereas the different rates of U excision from the substrates of the same size but containing U in different positions are largely due to different V,,, values.
Low‐loss, infrared and terahertz nanophotonics using surface phonon polaritons (2014)

Abstract The excitation of surface‐phonon‐polariton (SPhP) modes in polar dielectric crystals and the associated new developments in the field of SPhPs are reviewed. The emphasis of this work is on providing an understanding of the general phenomenon, including the origin of the Reststrahlen band, the role that optical phonons in polar dielectric lattices play in supporting sub‐diffraction‐limited modes and how the relatively long optical phonon lifetimes can lead to the low optical losses observed within these materials. Based on this overview, the achievements attained to date and the potential technological advantages of these materials are discussed for localized modes in nanostructures, propagating modes on surfaces and in waveguides and novel metamaterial designs, with the goal of realizing low‐loss nanophotonics and metamaterials in the mid‐infrared to terahertz spectral ranges.

Burst wave lithotripsy: An in vivo demonstration of efficacy and acute safety using a porcine model (2018)

Burst wave lithotripsy (BWL) is a new non-invasive method for stone comminution using bursts of sub-megahertz ultrasound. A porcine model of urolithiasis and techniques to implement BWL treatment have been developed to evaluate its effectiveness and acute safety. Five human calcium oxalate monohydrate stones (6–7 mm) were hydrated, weighed, and surgically implanted into the kidneys of three pigs. Transcutaneous stone treatments were performed with a BWL transducer coupled to the skin via an external water bath. Stone targeting and treatment monitoring were performed with a co-aligned ultrasound imaging probe. Treatment exposures were applied in three 10-minute intervals for each stone. If sustained cavitation in the parenchyma was observed by ultrasound imaging feedback, treatment was paused and the pressure amplitude was decreased for the remaining time. Peak negative focal pressures between 6.5 and 7 MPa were applied for all treatments. After treatment, stone fragments were removed from the kidneys. At least 50% of each stone was reduced to &amp;lt;2 mm fragments. 100% of four stones were reduced to &amp;lt;4 mm fragments. Magnetic resonance imaging showed minimal injury to the functional renal volume. This study demonstrated that BWL can be used to effectively fragment kidney stones with minimal injury.

Minimum points and views for the recovery of three-dimensional structure. (1987)

Mathematical analyses of motion perception have established minimum combinations of points and distinct views that are sufficient to recover three-dimensional (3D) structure from two-dimensional (2D) images, using such regularities as rigid motion, fixed axis of rotation, and constant angular velocity. To determine whether human subjects could recover 3D information at these theoretical levels, we presented subjects with pairs of displays and asked them to determine whether they represented the same or different 3D structures. Number of points was varied between two and five; number of views was varied between two and six; and the motion was fixed axis with constant angular velocity, fixed axis with variable velocity, or variable axis with variable velocity. Accuracy increased with views, decreased with points, and was greater with fixed-axis motion. Subjects performed above chance levels even when motion was eliminated, indicating that they exploited regularities in addition to those in the theoretical analyses.

Optimal assessment of MGMT status as a prognostic biomarker for patients with newly diagnosed GBM treated with chemoradiation requires determination of both promoter methylation and IHC protein expression.
A new Integrated LWD platform delivers improved Drilling Efficiency, Well Placement, and Formation Evaluation services (2005)

Abstract Logging-while-drilling (LWD) services are today often provided by several separate tools that, when used in combination, result in some measurements being made far from the bit. Time to make up and break out LWD tools, memory dumping, as well as multiple tool reliability issues can significantly add to the well construction costs. An innovative new LWD tool has been developed to simultaneously provide drilling-related measurements and an industry standard suite of formation evaluation measurements, equivalent to the classic "triple-combo" service, but co-located and closer to the bit, using only a single short collar. This means that less rathole is needed for logging, and fewer collar connections have to be made, resulting in a more efficient drilling operation. In addition, the co-location of the sensors reduces uncertainties in the interpretation of measurements that rely on multiple sensors. A key focus during the development of the tool has been improvement in service delivery. This has been achieved through increased operational efficiency, higher rate of penetration (ROP) capability, significantly improved reliability throughout the system, and greater ease of maintenance. The use of a pulsed neutron source instead of a chemical source also dramatically reduces the environmental and operational risks normally encountered with the use of traditional LWD tools. Pulsed neutron measurements delivered by this service include formation capture cross section (sigma) and elemental analysis from neutron capture spectroscopy. These new measurements are used to compute mineralogy while drilling. Azimuthal measurements are also available, allowing the formation and borehole to be imaged using a variety of properties. The result is a robust and complete interpretation with significantly reduced uncertainty, as well as a large choice of steering methods for effective well placement. In this paper we describe the development of this new LWD service and show field-test examples of improved formation evaluation, increased drilling efficiency, and more effective well placement that the tool has provided.
Ovarian vein thrombosis in pregnancy (2023)

The aim of this study is to summarize the literature on this problem and to analyze the frequency, differential diagnosis, and management of OVT. The article highlights three observations of ovarian vein thrombosis and thrombophlebitis diagnosed after spontaneous and operative vaginal deliveries. Key words: pregnancy complications, postpartum period, thrombosis, thrombophlebitis, ovarian vein
Idiotype regulation of the anti-bovine serum albumin response. I. Generation of an idiotype-specific Lyt-1-2+ suppressor T cell. (1987)

A monoclonal antibody (3C-7) specific for a determinant localized on the carboxy-terminus of the BSA molecule (P505-582) has been shown to cause suppression of the multispecific BSA antibody response if given i.v. before immunization. The fine binding specificity and the isotype subclass are not responsible for the suppression generated. Administration of 3C-7 i.v. results in the generation of a suppressor T cell that, when transferred into reconstituted irradiated mice, results in a diminished anti-BSA response. Suppression can be eliminated by panning T cells on idiotype (3C-7) coated plates, but not by panning on BSA, polyclonal anti-BSA antibodies, or MOPC 21. The action of the cell is antigen (BSA) specific. Idiotype-binding T cells reconstitute suppression and appear to be Lyt-1-2+. These observations demonstrate that a limited set of monoclonal antibodies directed against a single determinant on a protein molecule have the capacity to regulate the immune response to a multiplicity of determinants present on the same protein. These data support the concept of antibody-induced regulation by the induction of suppressor cells through idiotype recognition.
Fuzzy-Based Optimal Adaptive Line-of-Sight Path Following for Underactuated Unmanned Surface Vehicle with Uncertainties and Time-Varying Disturbances (2018)

This paper investigates the path following control problem for an underactuated unmanned surface vehicle (USV) in the presence of dynamical uncertainties and time-varying external disturbances. Based on fuzzy optimization algorithm, an improved adaptive line-of-sight (ALOS) guidance law is proposed, which is suitable for straight-line and curve paths. On the basis of guidance information provided by LOS, a three-degree-of-freedom (DOF) dynamic model of an underactuated USV has been used to design a practical path following controller. The controller is designed by combining backstepping method, neural shunting model, neural network minimum parameter learning method, and Nussbaum function. Neural shunting model is used to solve the problem of “explosion of complexity,” which is an inherent illness of backstepping algorithm. Meanwhile, a simpler neural network minimum parameter learning method than multilayer neural network is employed to identify the uncertainties and time-varying external disturbances. In particular, Nussbaum function is introduced into the controller design to solve the problem of unknown control gain coefficient. And much effort is made to obtain the stability for the closed-loop control system, using the Lyapunov stability theory. Simulation experiments demonstrate the effectiveness and reliability of the improved LOS guidance algorithm and the path following controller.

Whole-exome sequencing identifies novel MPL and JAK2 mutations in triple-negative myeloproliferative neoplasms (2015)

Essential thrombocythemia (ET) and primary myelofibrosis (PMF) are chronic diseases characterized by clonal hematopoiesis and hyperproliferation of terminally differentiated myeloid cells. The disease is driven by somatic mutations in exon 9 of CALR or exon 10 of MPL or JAK2-V617F in >90% of the cases, whereas the remaining cases are termed "triple negative." We aimed to identify the disease-causing mutations in the triple-negative cases of ET and PMF by applying whole-exome sequencing (WES) on paired tumor and control samples from 8 patients. We found evidence of clonal hematopoiesis in 5 of 8 studied cases based on clonality analysis and presence of somatic genetic aberrations. WES identified somatic mutations in 3 of 8 cases. We did not detect any novel recurrent somatic mutations. In 3 patients with clonal hematopoiesis analyzed by WES, we identified a somatic MPL-S204P, a germline MPL-V285E mutation, and a germline JAK2-G571S variant. We performed Sanger sequencing of the entire coding region of MPL in 62, and of JAK2 in 49 additional triple-negative cases of ET or PMF. New somatic (T119I, S204F, E230G, Y591D) and 1 germline (R321W) MPL mutation were detected. All of the identified MPL mutations were gain-of-function when analyzed in functional assays. JAK2 variants were identified in 5 of 57 triple-negative cases analyzed by WES and Sanger sequencing combined. We could demonstrate that JAK2-V625F and JAK2-F556V are gain-of-function mutations. Our results suggest that triple-negative cases of ET and PMF do not represent a homogenous disease entity. Cases with polyclonal hematopoiesis might represent hereditary disorders.
Second-Order Asymptotics of Rate-Distortion using Gaussian Codebooks for Arbitrary Sources (2018)

The rate-distortion saddle-point problem considered by Lapidoth (1997) consists in finding the minimum rate to compress an arbitrary ergodic source when one is constrained to use a random Gaussian codebook and minimum (Euclidean) distance encoding is employed. We extend Lapidoth's analysis in several directions in this paper. Firstly, we consider second-order asymptotics. In particular, when the source is stationary and memoryless, we establish ensemble tight second-order coding rate for the problem. Secondly, by “random Gaussian codebook”, Lapidoth refers to a collection of random codewords, each of which is drawn independently and uniformly from the surface of an n-dimensional sphere. To be more precise, we term this as a spherical Gaussian codebook. We also consider i.i.d. Gaussian codebooks in which each random codeword is drawn independently from a product Gaussian distribution. We also derive the second-order asymptotics when i.i.d. Gaussian codebooks are employed. Interestingly, in contrast to the recent work on the channel coding counterpart by Scarlett, Tan and Durisi (2017), the dispersions for spherical and i.i.d. Gaussian code books are identical for the rate-distortion saddle-point problem.

Physical Characteristics of Xenon Flashtubes (1964)

The physical characteristics of xenon flashtubes are reviewed. In particular, the spectral output of xenon lamps is discussed in terms of watts per unit wavelength for different wavelengths and current densities. Attention is given to the effects of varying the pressure, length and diameter of the flashtube on the total light output, and the conversion efficiency of electrical to optical power. Additionally, the influence of the exciting pulse shape on the conversion efficiency is described, along with some problems in impedance matching for the driving source.
Point Cloud Processing System Development Based on PCL and Qt (2019)

LiDAR technology has been widely applied in various disciplines as it can obtain 3D information of targets directly and accurately. However, it is still a challenge to processing LiDAR point clouds efficiently as its huge datasets and complicated processing procedures. Current processing methods need integrate multiple software to complete the whole processing procedures to produce final results which needs lots of time effort and cause low efficiency. By analyzing the theories and methods of LiDAR data processing procedures, this research aims to develop a new point cloud processing software based on PCL and Qt. Firstly, the overall design and modules of the processing system was introduced. The main modules include data management, visualization, filtering, segmentation modeling and auxiliary function. Secondly, to improve system security and maintenance convenience, the system adopts the object-oriented programming method to encapsulate private members and methods of classes, and only open public member variables and methods are available to users. The main classes which were employed in this research were explained. Finally, indoor environments datasets were used to verify the point cloud processing system. The results showed that system has strong interactivity, intuitive display, easy to use and comprehensive features and good results can be derived.
Magnetorotons in quasi-one-dimensional electron systems in the absence of Kohn’s theorem (1992)

Using a time-dependent Hartree-Fock approximation we have investigated the inter-Landau-level collective excitation spectrum of quasi-one-dimensional electron gases where Kohn's theorem is violated. We find that the spectrum develops a roton minimum at finite wave vectors. In addition to the main magnetoroton, extra collective modes are found. Also we find that it is important to include both the Hartree and exchange local-field corrections in a calculation of the cyclotron resonance.
Synchronisation and coupling analysis: Applied cardiovascular physics in sleep medicine (2013)

Sleep is a physiological process with an internal program of a number of well defined sleep stages and intermediate wakefulness periods. The sleep stages modulate the autonomous nervous system and thereby the sleep stages are accompanied by different regulation regimes for the cardiovascular and respiratory system. The differences in regulation can be distinguished by new techniques of cardiovascular physics. The number of patients suffering from sleep disorders increases unproportionally with the increase of the human population and aging, leading to very high expenses in the public health system. Therefore, the challenge of cardiovascular physics is to develop highly-sophisticated methods which are able to, on the one hand, supplement and replace expensive medical devices and, on the other hand, improve the medical diagnostics with decreasing the patient's risk. Methods of cardiovascular physics are used to analyze heart rate, blood pressure and respiration to detect changes of the autonomous nervous system in different diseases. Data driven modeling analysis, synchronization and coupling analysis and their applications to biosignals in healthy subjects and patients with different sleep disorders are presented. Newly derived methods of cardiovascular physics can help to find indicators for these health risks.

Properties of a phase-conjugate etalon mirror and its application to laser resonator spatial-mode control (2004)

The concept of a phase-conjugate etalon mirror consisting of one flat and one aspheric surface is introduced. This new element can be used as an end mirror of a conventional resonator to promote spatial-mode selection and mode shaping. A phase-conjugate etalon designed for the fundamental Gaussian mode is experimentally implemented and tested with a single-mode He-Ne laser.
Perpendicular magnetic anisotropy at the Fe/Au(111) interface studied by Mössbauer, x-ray absorption, and photoemission spectroscopies (2021)

The origin of the interfacial perpendicular magnetic anisotropy (PMA) induced in the ultrathin Fe layer on the Au(111) surface was examined using synchrotron-radiation-based M\"ossbauer spectroscopy (MS), x-ray magnetic circular dichroism (XMCD), and angle-resolved photoemission spectroscopy (ARPES). To probe the detailed interfacial electronic structure of orbital hybridization between the Fe $3d$ and Au $6p$ bands, we detected the interfacial proximity effect, which modulates the valence-band electronic structure of Fe, resulting in PMA. MS and XMCD measurements were used to detect the interfacial magnetic structure and anisotropy in orbital magnetic moments, respectively. In situ ARPES also confirms the initial growth of Fe on large spin-orbit coupled surface Shockley states under Au(111) modulated electronic states in the vicinity of the Fermi level. This suggests that PMA in the Fe/Au(111) interface originates from the cooperation effects among the spin, orbital magnetic moments in Fe, and large spin-orbit coupling in Au. These findings pave the way to develop interfacial PMA using $p\text{\ensuremath{-}}d$ hybridization with a large spin-orbit interaction.
