title: Properties of two DNA helicases of human cells.
Creators: name: Ochem, Alexander
Publisher: name: The Open University
Year: 1999

description: DNA helicases are ubiquitous, non-specific dsDNA unwinding enzymes involved in all aspects of DNA metabolism. In the present work, I describe the properties of two DNA helicases of HeLa cells: those of a novel enzyme, human DNA helicase VH (HDH VII), and those of the separate subunits of human DNA helicase II.
 HDH VII possesses the highest specific activity among all the helicases, so far, extracted and characterized from HeLa cells, and this activity is further stimulated nearly a hundred-fold by hRPA. However, its abundance in the cell is very low since only 1 lOpg of pure protein could be recovered from 150 grams of cultured cells. The estimated molecular weight of HDH YD in its native form is close to 90-kDa whereas SDS-PAGE analysis reveals two unequal, closely-migrating bands in the region of 32-kDa, suggesting that the protein may have a hetero-trimeric conformation. The enzyme exhibits a double polarity of translocation: a property that distinguishes it from all characterized eukaryotic DNA helicases. In spite of its high specific activity, HDH VH shows a relatively low processivity even in the presence of hRPA and cannot unwind duplexes longer than 17 base pairs.
 The Ku antigen consists of two subunits of 70 and 83 kDa, separable from each other only by electrophoresis under denaturing conditions, and is endowed with both duplex DNA end-binding capacity and helicase activity. I have dissected the in vitro activities of the Ku molecule, and I report that whereas the DNA end-binding property remains a prerogative of the heterodimer, the helicase activity of the Ku molecule resides exclusively in the 70 kDa subunit, and that the helicase activity of the Ku heterodimer is stimulated upon phosphorylation by the DNA-dependent protein kinase DNA-PK.

description: We study the scalar potential and the mass spectrum of the supersymmetric extension of a three-family model based on the local gauge group $SU(3)_C\otimes SU(3)_L\otimes U(1)_X$, with anomalies canceled among the three families in a nontrivial fashion. In this model the slepton multiplets play the role of the Higgs scalars and no Higgsinos are needed, with the consequence that the sneutrino, the selectron and six other sleptons play the role of the Goldstone bosons of the theory. By introducing an Abelian anomaly-free discrete symmetry and aligning the vacuum in a convenient way, we get a consistent mass spectrum for the scalars and for the spin 1/2 quarks and charged leptons, where only the top and charm quarks and the tau lepton acquire tree level masses while the remaining ordinary charged fermions acquire radiative hierarchical masses.

description: Aims. In this work, we aim to make a differential comparison of the neutron-capture and p-process element molybdenum (Mo) in the stellar populations in the local disk(s) and the bulge, focusing on minimising possible systematic effects in the analysis. Methods. The stellar sample consists of 45 bulge and 291 local disk K-giants, observed with high-resolution optical spectra. The abundances are determined by fitting synthetic spectra using the SME-code. The disk sample is separated into thin- and thick-disk components using a combination of abundances and kinematics. The cosmic origin of Mo is investigated and discussed by comparing with previous published abundances of Mo and the neutron-capture elements cerium (Ce) and europium (Eu). Results. We determine reliable Mo abundances for 35 bulge and 282 disk giants with a typical uncertainty of [Mo/Fe]~0.2 and ~0.1 dex for the bulge and disk, respectively. Conclusions. We find that the bulge possibly is enhanced in [Mo/Fe] compared to the thick disk, which we do not observe in either [Ce/Fe] nor [Eu/Fe]. This might suggest a higher past star-formation rate in the bulge, however, since we do not observe the bulge to be enhanced in [Eu/Fe], the origin of the molybdenum enhancement is yet to be constrained. Although, the scatter is large, we may be observing evidence of the p-process contributing to the heavy element production in the chemical evolution of the bulge.

description: The Women’s Empowerment in Agriculture Index (WEAI) can be a useful tool to measure the empowerment, agency and inclusion of women in the agriculture sector. However, computing the WEAI in its current form involves large data requirements, resulting in lengthy surveys with several questions on various dimensions and indicators within each dimension. This paper proposes a reduced version of the WEAI, or the R-WEAI, and examines two possible approaches to reduce the data requirements while ensuring comparability to the full WEAI.

description: Nutrition Improvement Projects (NIPs) are sets of planned activities specifically undertaken as interventions to reduce malnutrition and its associated problems in the communities. The study focused on five NIPs of varying nature. The projects included the internationally known Iringa Nutrition Project, and the National Salt Iodation Project. Others include, a locally processed weaning food, and smallholder agricultural-based projects. The aligning of institutions for delivering primary health services attempted by some nutrition improvement projects in Tanzania seems to be in disharmony with the organisational capacities, and therefore causing high transaction costs. On the other hand, things look promising for the deliverance of non-public good services. The private sector - through the use of market mechanism, and more involvement of the civil society as a way of increasing the participation of beneficiaries, hold the key to success for that matter. Such arrangements are likely to be favoured by the continuing economic changes in the country.

description: Magnetic fields and turbulence are important components of the interstellar medium (ISM) of star-forming galaxies. It is challenging to measure the properties of the small-scale ISM magnetic fields (magnetic fields at scales smaller than the turbulence driving scale). Using numerical simulations, we demonstrate how the second-order rotation measure (RM, which depends on thermal electron density, $n_{\rm e}$, and magnetic field, $b$) structure function can probe the properties of small-scale $b$. We then apply our results to observations of the Small and Large Magellanic Clouds (SMC and LMC). First, using Gaussian random $b$, we show that the characteristic scale where the RM structure function flattens is approximately equal to the correlation length of $b$. We also show that computing the RM structure function with a higher-order stencil (more than the commonly-used two-point stencil) is necessary to accurately estimate the slope of the structure function. Then, using Gaussian random $b$ and lognormal $n_{\rm e}$ with known power spectra, we derive an empirical relationship between the slope of the power spectrum of $b$, $n_{\rm e}$, and RM. We apply these results to the SMC and LMC and estimate the following properties of small-scale $b$: correlation length ($160~\pm 21~{\rm pc}$ for the SMC and $87~\pm~17~{\rm pc}$ for the LMC), strength ($14~\pm 2~μ{\rm G}$ for the SMC and $15~\pm 3~μ{\rm G}$ for the LMC), and slope of the magnetic power spectrum ($-1.3~\pm~0.4$ for the SMC and $-1.6~\pm~0.1$ for the LMC). We also find that $n_{\rm e}$ is practically constant over the estimated $b$ correlation scales.

description: We study the feasibility of meaningful proof-of-principle demonstrations of several quantum repeater protocols with photon (single-photon and photon-pair) sources and atomic-ensemble based quantum memories. We take into account non-unit memory efficiencies that decay exponentially with time, which complicates the calculation of repeater rates. We discuss implementations based on quantum dots, parametric down-conversion, rare-earth-ion doped crystals, and Rydberg atoms. Our results provide guidance for the near-term implementation of long-distance quantum repeater demonstrations, suggesting that such demonstrations are within reach of current technology.

description: Click-through rate (CTR) prediction is an essential task in industrial applications such as video recommendation. Recently, deep learning models have been proposed to learn the representation of users' overall interests, while ignoring the fact that interests may dynamically change over time. We argue that it is necessary to consider the continuous-time information in CTR models to track user interest trend from rich historical behaviors. In this paper, we propose a novel Deep Time-Stream framework (DTS) which introduces the time information by an ordinary differential equations (ODE). DTS continuously models the evolution of interests using a neural network, and thus is able to tackle the challenge of dynamically representing users' interests based on their historical behaviors. In addition, our framework can be seamlessly applied to any existing deep CTR models by leveraging the additional Time-Stream Module, while no changes are made to the original CTR models. Experiments on public dataset as well as real industry dataset with billions of samples demonstrate the effectiveness of proposed approaches, which achieve superior performance compared with existing methods.

description: Millimeter-wave (mmWave) band (30 - 300 GHz) is an emerging spectrum range for wireless communication, short-range radar and sensor applications. mmWave-optic modulators that could efficiently convert mmWave signals into optical domain are crucial components for long-haul transmission of mmWave signals through optical networks. At these ultrahigh frequencies, however, the modulation performances are highly sensitive to the transmission line loss as well as the velocity- and impedance-matching conditions, while precise measurements and modeling of these parameters are often non-trivial. Here we present a systematic investigation of the mmWave-optic modulation performances of thin-film lithium niobate modulators through theoretical modeling, electrical verifications and electro-optic measurements at frequencies up to 325 GHz. Based on our experimentally verified model, we demonstrate thin-film lithium niobate mmWave-optic modulators with a measured 3-dB electro-optic bandwidth of 170 GHz and a 6-dB bandwidth of 295 GHz. The device also shows a low RF half-wave voltage of 7.3 V measured at an ultrahigh modulation frequency of 250 GHz. This work provides a comprehensive guideline for the design and characterization of mmWave-optic modulators and paves the way toward future integrated mmWave photonic systems for beyond-5G communication and radar applications.

description: The main goal of our paper is the study of several classes of submanifolds of generalized complex manifolds. Along with the generalized complex submanifolds defined by Gualtieri and Hitchin (we call these ``generalized Lagrangian submanifolds'' in our paper), we introduce and study three other classes of submanifolds. For generalized complex manifolds that arise from complex (resp., symplectic) manifolds, all three classes specialize to complex (resp., symplectic) submanifolds. In general, however, all three classes are distinct. We discuss some interesting features of our theory of submanifolds, and illustrate them with a few nontrivial examples. We then support our ``symplectic/Lagrangian viewpoint'' on the submanifolds introduced by Gualtieri and Hitchin by defining the ``generalized complex category'', modelled on the constructions of Guillemin-Sternberg and Weinstein. We argue that our approach may be useful for the quantization of generalized complex manifolds.

description: Transition-metal oxide films, demonstrating the effects of both threshold and nonvolatile memory resistive switching, have been recently proposed as candidate materials for storage-class memory. In this work we describe some experimental results on threshold switching in a number of various transition metal (V, Ti, Fe, Nb, Mo, W, Hf, Zr, Mn, Y, and Ta) oxide films obtained by anodic oxidation. Then, the results concerning the effects of bistable resistive switching in MOM and MOS structures on the basis of such oxides as V2O5, Nb2O5, and NiO are presented. It is shown that sandwich structures on the basis of the Au/V2O5/SiO2/Si, Nb/Nb2O5/Au, and Pt/NiO/Pt can be used as memory elements for ReRAM applications. Finally, model approximations are developed in order to describe theoretically the effect of nonvolatile unipolar switching in Pt NiO-Pt structures.

description: Accurate temperature measurements are essential for the proper monitoring and control of industrial furnaces. However, measurement uncertainty is a risk for such a critical parameter. Certain instrumental and environmental errors must be considered when using spectral-band radiation thermometry techniques, such as the uncertainty in the emissivity of the target surface, reflected radiation from surrounding objects, or atmospheric absorption and emission, to name a few. Undesired contributions to measured radiation can be isolated using measurement models, also known as error-correction models. This paper presents a methodology for budgeting significant sources of error and uncertainty during temperature measurements in a petrochemical furnace scenario. A continuous monitoring system is also presented, aided by a deep-learning-based measurement correction model, to allow domain experts to analyze the furnace's operation in real-time. To validate the proposed system's functionality, a real-world application case in a petrochemical plant is presented. The proposed solution demonstrates the viability of precise industrial furnace monitoring, thereby increasing operational security and improving the efficiency of such energy-intensive systems.

Exploring the spectrum of the hidden charm strange pentaquark in an SU(4) flavor-spin model

Year: 2020
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We study the spectrum of the isoscalar pentaquark $udsc\overline{c}$, of either positive or negative parity, in a constituent quark model with linear confinement and a flavor-spin hyperfine interaction previously extended to SU(4) and used to describe the spectrum of the $uudc\overline{c}$ pentaquarks observed at LHCb in 2019. For positive parity we make a distinction between the case where one unit of angular momentum is located in the subsystem of four quarks and the case where the angular momentum is located in the relative motion between a ground state four-quark subsystem and the antiquark. The novelty is that we introduce the coupling between different flavor states, due to the breaking of exact SU(4)-flavor symmetry of the Hamiltonian model, both for positive and negative parity states. An important consequence is that the lowest state, located at 4404 MeV, has quantum numbers $J^P$ = $1/2^-$ while without coupling the lowest state has $J^P$ = $1/2^+$ or $3/2^+$.

description: Even though China has no rule of law tradition, it has been making rapid progress – since 1978 when the policy of opening-up was adopted – in setting up a legal system that is supportive of a market economy. This paper contains a comprehensive overview of legal reforms in China. Section 2 summarizes the reforms over the last 20 years and describes the prospects for further reform. Section 3 describes constitutional reforms since 1949, including the important reform of March 1999 which has written into the Constitution the principle of the rule of law. This section also describes reforms in various areas of public law, including criminal law and criminal procedure; administrative law; regulatory powers of the government; and describes the changing role of the People’s Congress. Section 4—which is the lengthiest—describes reforms in private law. Successively, the paper reviews corporate legislation, securities, competition, consumer protection, labor law, intellectual property, finance and guarantees. Section 5 covers social security as well as environmental protection. Section 6 discusses legal reforms that affect rural areas. Section 7 covers judicial reform issues, including combating corruption; open trials; the lay assessor system; township courts; dispute resolution issues; and the enforcement ofjudgements. Finally, section 8 concludes by discussing how to promote legality in China and the role of lawyers.

We start from a microscopic lattice-gas model with charged particles, and build mean-field kinetic equations following the lines of earlier work for neutral particles. We include the Poisson equation to account for the influence of the electric field on ion migration, and oxido-reduction processes on the electrode surfaces to allow for growth and dissolution. We confirm the viability of our approach by simulating (i) the electrochemical equilibrium at flat electrodes, which displays the correct charged double-layer, (ii) the growth kinetics of one-dimensional electrochemical cells during growth and dissolution, and (iii) electrochemical dendrites in two dimensions.

description: This paper examines the role of the Consortium Soja du Bénin (CSB) in addressing constraints related to soybean value chains in Benin. The methodology applied consisted of desk research, observation, focus group discussions with two soy women cooperatives, field visits, interview with the consortium members and an evaluation workshop with 13 partners involved in the ‘Project Soy Afitin and Milk’-ProSAM (with financial support from the European Commission’s Directorate-General for International Cooperation and Development through the Forum for Agricultural Research in Africa (FARA)/Platform for African-European Partnerships for Agricultural Research for Development (PAEPARD)”. The CSB is a dynamic multi-stakeholder innovation platform initiated in 2011 to improve soybean value chains in Benin. This paper focused on ProSAM implementation, one of the CSB projects, which aims to increase household income through improved food chain of soybean derived products (milk and afitin). The improved soy milk shelf life from one day to six months and the formulation of a soybean-based taste enhancer, ‘Dadonu’, are two results from the collaboration among CSB partners. The commitment of each partner to participate in the innovation and knowledge co-creation process, the good co-ordination mechanism, the internal facilitation, the effective internal and external communication contributed to these achievements and to the overall successful implementation of the project. Furthermore, the dynamic nature of the consortium, especially in identifying strategic partners to develop projects has yielded significant outputs considering the size of resources mobilized for the implementation of other projects. Other multi-stakeholder platforms can capitalize on these experiences to effectively generate innovations and efficiently tackle constraints in the agricultural sector.

description: Effective interactions between like-charged particles immersed in an electrolyte solution were calculated using two integral equation theories, hypernetted-chain (HNC)-Ornstein--Zernike (OZ) and ionic Percus--Yevick 2 (IPY2)-OZ. When the HNC-OZ theory was adopted, the electrolyte concentration dependence of the effective interaction showed a reentrant behavior. By contrast, the IPY2-OZ theory did not indicate the behavior. Monte Carlo simulations were performed for one of the model systems, and the results agreed qualitatively with those calculated using the HNC-OZ theory.

description: When an electron-hole pair is optically excited in a semiconductor quantum dot the host crystal lattice needs to adapt to the presence of the generated charge distribution. Therefore the coupled exciton-phonon system has to establish a new equilibrium, which is reached in the form of a quasiparticle called polaron. Especially, when the exciton is abruptly generated on a timescale faster than the typical lattice dynamics, the lattice displacement cannot follow adiabatically. Consequently, a rich dynamics on the picosecond timescale of the coupled system is expected. In this study we combine simulations and measurements of the ultrafast, coherent, nonlinear optical response, obtained by four-wave mixing spectroscopy, to resolve the formation of this polaron. By detecting and investigating the phonon sidebands in the four-wave mixing spectra for varying pulse delays and different temperatures we have access to the influence of phonon emission and absorption processes which finally result in the emission of an acoustic wave packet out from the quantum dot.

description: Dynamic mode decomposition (DMD) is an emerging methodology that has recently attracted computational scientists working on nonintrusive reduced order modeling. One of the major strengths that DMD possesses is having ground theoretical roots from the Koopman approximation theory. Indeed, DMD may be viewed as the data-driven realization of the famous Koopman operator. Nonetheless, the stable implementation of DMD incurs computing the singular value decomposition of the input data matrix. This, in turn, makes the process computationally demanding for high dimensional systems. In order to alleviate this burden, we develop a framework based on sketching methods, wherein a sketch of a matrix is simply another matrix which is significantly smaller, but still sufficiently approximates the original system. Such sketching or embedding is performed by applying random transformations, with certain properties, on the input matrix to yield a compressed version of the initial system. Hence, many of the expensive computations can be carried out on the smaller matrix, thereby accelerating the solution of the original problem. We conduct numerical experiments conducted using the spherical shallow water equations as a prototypical model in the context of geophysical flows. The performance of several sketching approaches is evaluated for capturing the range and co-range of the data matrix. The proposed sketching-based framework can accelerate various portions of the DMD algorithm, compared to classical methods that operate directly on the raw input data. This eventually leads to substantial computational gains that are vital for digital twinning of high dimensional systems.

description: We investigate the evolution of a system composed of $N$ non-interacting point particles of mass $m$ in a container divided into two chambers by a movable adiabatic piston of mass $M\gg m$. Using a two-time-scale perturbation approach in terms of the small parameter $α=2m/(M+m)$, we show that the evolution towards thermal equilibrium proceeds in two stages. The first stage is a fast, deterministic, adiabatic relaxation towards mechanical equilibrium. The second stage, which takes place at times ${\cal O}(M)$, is a slow fluctuation-driven, diathermic relaxation towards thermal equilibrium. A very simple equation is derived which shows that in the second stage, the position of the piston is given by $X_M(t)=L[1/2-ξ(αt)]$ where the function $ξ$ is independent of $M$. Numerical simulations support the assumptions underlying our analytical derivations and illustrate the large mass range in which the picture holds.

description: It is expected that the next generation of high-contrast imaging instruments will deliver the first unresolved image of an extrasolar planet. The emitted thermal infrared light from the planet should show no phase effect assuming the planet is in thermal equilibrium. But the reflected visible light will vary versus the phase angle. Here, we study the photometric variation of the reflected light versus the orbital phase of a ringed extrasolar planet. We show that a ring around an extrasolar planet, both obviously unresolved, can be detected by its specific photometric signature. A simple quantitative model is discussed, taking into account the basic optical and geometrical properties of the ringed planet.

description: Gravitational waves from binary black hole mergers have allowed us to directly observe stellar-mass black hole binaries for the first time, and therefore explore their formation channels. One of the ways to infer how a binary system is assembled is by measuring the system's orbital eccentricity. Current methods of parameter estimation do not include all physical effects of eccentric systems such as spin-induced precession, higher-order modes, and the initial argument of periapsis: an angle describing the orientation of the orbital ellipse. We explore how varying the argument of periapsis changes gravitational waveforms and study its effect on the inference of astrophysical parameters. We use the eccentric spin-aligned waveforms TEOBResumS and SEOBNRE to measure the change in the waveforms as the argument of periapsis is changed. We find that the argument of periapsis could already be impacting analyses performed with TEOBResumS. However, it is likely to be well-resolvable in the foreseeable future only for the loudest events observed by LIGO--Virgo--KAGRA. The systematic error in previous, low-eccentricity analyses that have not considered the argument of periapsis is likely to be small.

description: Thermal frequency fluctuations in optical cavities limit the sensitivity of precision experiments ranging from gravitational wave observatories to optical atomic clocks. Conventional modeling of these noises assumes a linear response of the optical field to the fluctuations of cavity frequency. Fundamentally, however, this response is nonlinear. Here we show that nonlinearly transduced thermal fluctuations of cavity frequency can dominate the broadband noise in photodetection, even when the magnitude of fluctuations is much smaller than the cavity linewidth. We term this noise "thermal intermodulation noise" and show that for a resonant laser probe it manifests as intensity fluctuations. We report and characterize thermal intermodulation noise in an optomechanical cavity, where the frequency fluctuations are caused by mechanical Brownian motion, and find excellent agreement with our developed theoretical model. We demonstrate that the effect is particularly relevant to quantum optomechanics: using a phononic crystal $Si_3N_4$ membrane with a low mass, soft-clamped mechanical mode we are able to operate in the regime where measurement quantum backaction contributes as much force noise as the thermal environment does. However, in the presence of intermodulation noise, quantum signatures of measurement are not revealed in direct photodetectors. The reported noise mechanism, while studied for an optomechanical system, can exist in any optical cavity.
