Rhamnogalacturonan I (RG-I) pectin are regarded as strong galectin-3 (Gal-3) antagonist because of galactan sidechains. The present study focused on discussing the effects of more structural regions in pectin on the antiGal-3 activity. The water-soluble pectin (WSP) recovered from citrus canning processing water was categorized as RG-I pectin. The controlled enzymatic hydrolysis was employed to sequentially remove the α-1,5-arabinan, homogalaturonan and β-1,4-galactan in WSP. The Gal-3-binding affinity KD (kd/ka) of WSP and debranched pectins were calculated to be 0.32 μM, 0.48 μM, 0.56 μM and 1.93 μM. Moreover, based on the more sensitive cell line (MCF-7) model, the IC30 value of WSP was lower than these of modified pectins, indicating decreased anti-Gal-3 activity. Our results suggested that the total amount of neutral sugar sidechains, the length of arabinan and cooperation between HG and RG-I played important roles in the anti-Gal-3 activity of WSP, not the Gal/Ara ratio or RG-I/HG ratio. These results provided a new insight into structure-activity relationship of citrus segment membrane RG-I as a galectin-3 antagonist and a new functional food.
Concentration Inequalities of Random Matrices and Solving Ptychography with a Convex Relaxation

Random matrix theory has seen rapid development in recent years. In particular, researchers have developed many non-asymptotic matrix concentration inequalities that parallel powerful scalar concentration inequalities. In this thesis, we focus on three topics: 1) estimating sparse covariance matrix using matrix concentration inequalities, 2) constructing the matrix phi-entropy to derive matrix concentration inequalities, 3) developing scalable algorithms to solve the phase recovery problem of ptychography based on low-rank matrix factorization. Estimation of covariance matrix is an important subject. In the setting of high dimensional statistics, the number of samples can be small in comparison to the dimension of the problem, thus estimating the complete covariance matrix is unfeasible. By assuming that the covariance matrix satisfies some sparsity assumptions, prior work has proved that it is feasible to estimate the sparse covariance matrix of Gaussian distribution using the masked sample covariance estimator. In this thesis, we use a new approach and apply non-asymptotic matrix concentration inequalities to obtain tight sample bounds for estimating the sparse covariance matrix of subgaussian distributions. The entropy method is a powerful approach in developing scalar concentration inequalities. The key ingredient is the subadditivity property that scalar entropy function exhibits. In this thesis, we construct a new concept of matrix phi-entropy and prove that matrix phi-entropy also satisfies a subadditivity property similar to the scalar form. We apply this new concept of matrix phi-entropy to derive non-asymptotic matrix concentration inequalities. Ptychography is a computational imaging technique which transforms low-resolution intensity-only images into a high-resolution complex recovery of the signal. Conventional algorithms are based on alternating projection, which lacks theoretical guarantees for their performance. In this thesis, we construct two new algorithms. The first algorithm relies on a convex formulation of the ptychography problem and on low-rank matrix recovery. This algorithm improves traditional approaches' performance but has high computational cost. The second algorithm achieves near-linear runtime and memory complexity by factorizing the objective matrix into its low-rank components and approximates the first algorithm's imaging quality.
Synaptic up-scaling preserves motor circuit output after chronic, natural inactivity

Neural systems use homeostatic plasticity to maintain normal brain functions and to prevent abnormal activity. Surprisingly, homeostatic mechanisms that regulate circuit output have mainly been demonstrated during artificial and/or pathological perturbations. Natural, physiological scenarios that activate these stabilizing mechanisms in neural networks of mature animals remain elusive. To establish the extent to which a naturally inactive circuit engages mechanisms of homeostatic plasticity, we utilized the respiratory motor circuit in bullfrogs that normally remains inactive for several months during the winter. We found that inactive respiratory motoneurons exhibit a classic form of homeostatic plasticity, up-scaling of AMPA-glutamate receptors. Up-scaling increased the synaptic strength of respiratory motoneurons and acted to boost motor amplitude from the respiratory network following months of inactivity. Our results show that synaptic scaling sustains strength of the respiratory motor output following months of inactivity, thereby supporting a major neuroscience hypothesis in a normal context for an adult animal.
In ation risk premia in the US and the euro area

We use a joint model of macroeconomic and term structure dynamics to estimate ination risk premia in the United States and the euro area, and to understand the macroeconomic determinants of such premia. Our results show that the ination risk premium is relatively small, positive, and increasing with the maturity. Moreover, the estimated ination premia vary over time as a result of changes to the state variables in the model. Speci cally, in both economies the output gap and ination are the main drivers of ination premia. The broad movements in long-term ination risk premia largely match those of the output gap, while more high-frequency premia uctuations seem to be aligned with changes in the level of ination. While we nd that ination premia always respond positively to upward ination shocks, the response to output gap shocks di¤er between the US and the euro area. A positive output shock results in a higher ination premium in the US, while it lowers it in the euro area. JEL classi cation numbers: E43, E44
In ation risk premia in the term structure of interest rates

This paper estimates the size and dynamics of ination risk premia in the euro area, based on a joint model of macroeconomic and term structure dynamics. Information from both nominal and index-linked yields is used in the empirical analysis. Our results indicate that term premia in the euro area yield curve reect predominantly real risks, i.e. risks which a¤ect the returns on both nominal and index-linked bonds. On average, ination risk premia were negligible during the EMU period but occasionally subject to statistically signi cant uctuations in 2004 2006. Movements in the raw break-even rate appear to have mostly reected such variations in ination risk premia, while long-term ination expectations have remained remarkably anchored from 1999 to date.

Information and its Presentation: Treatment Effects in Low-Information vs. High-Information Experiments

This article examines how the presentation of information during a laboratory experiment can alter a study’s findings. We compare four possible ways to present information about hypothetical candidates in a laboratory experiment. First, we manipulate whether subjects experience a low-information or a high-information campaign. Second, we manipulate whether the information is presented statically or dynamically. We find that the design of a study can produce very different conclusions. Using candidate’s gender as our manipulation, we find significant effects on a variety of candidate evaluation measures in low-information conditions, but almost no significant effects in high-information conditions. We also find that subjects in high-information settings tend to seek out more information in dynamic environments than static, though their ultimate candidate evaluations do not differ. Implications and recommendations for future avenues of study are discussed.
Observation of Fourier transform limited lines in hexagonal boron nitride

Single defect centers in layered hexagonal boron nitride are promising candidates as single-photon sources for quantum optics and nanophotonics applications. However, spectral instability hinders many applications. Here, we perform resonant excitation measurements and observe Fourier transform limited linewidths down to $\ensuremath{\approx}50$ MHz. We investigated the optical properties of more than 600 single-photon emitters (SPEs) in hBN. The SPEs exhibit narrow zero-phonon lines distributed over a spectral range from 580 to 800 nm and with dipolelike emission with a high polarization contrast. Finally, the emitters withstand transfer to a foreign photonic platform, namely, a silver mirror, which makes them compatible with photonic devices such as optical resonators and paves the way to quantum photonics applications.
Recent Developments and Results on Double Beta Decays with Crystal Scintillators and HPGe Spectrometry

Recent developments, results, and perspectives arising from double beta decay experiments at the Gran Sasso National Laboratory (LNGS) of the INFN by using HPGe detectors and crystal scintillators and by exploiting various approaches and different isotopes are summarized. The measurements here presented have been performed in the experimental set-ups of the DAMA collaboration. These setups are optimized for low-background studies and operate deep underground at LNGS. The presented results are of significant value to the field, and the sensitivity achieved for some of the considered isotopes is one of the best available to date.
A meshless method for Kirchho- plate bending problems

SUMMARYIn this work a meshless method for the analysis of bending of thin homogeneous plates is presented.This meshless method is based on the use of radial basis functions to build an approximation of thegeneral solution of the partial dierential equations governing the Kirchho plate bending problem. Inorder to obtain a symmetric and non-singular linear equation system the Hermite collocation methodis used. To assess the formulation a series of plates with dierent boundary conditions are analysed.Comparisons are made with other results available in the literature. Copyright ? 2001 John Wiley S meshless method; hermite collocation 1. INTRODUCTIONThe use of a mesh (be it domain or boundary one) is a basic characteristic of the traditionalapproaches for the solution of partial dierential equations (PDEs). This is the case forthe domain methods (such as the nite dierence methods, the nite element methods andthe nite volume methods) and also for boundary methods such as the boundary elementmethod. In the rst type of methods (the domain ones) assumptions are made for the localapproximation which require a mesh to support them. In the case of boundary methods,whereby an integral equation is obtained, a boundary mesh (and, in some cases such asthe case of physical nonlinearity, also a domain mesh) is required to obtain a numericalapproximation to the boundary integrals involved.Referring to the dominant approach, the nite element methods, the use of a mesh impliesthat specic procedures have to be devised just to dene the mesh. Also, and to keep theorder of the local approximation within reasonable (low) limits, the element size has to bereduced whenever better approximations are pursued.The extraordinary amount of work which has been put into FEM research since its earlydays, has, one way or another, circumvented these and other problems associated to the
Long-time asymptotics for the derivative nonlinear Schrödinger equation on the half-line

We derive asymptotic formulas for the solution of the derivative nonlinear Schrödinger equation on the half-line under the assumption that the initial and boundary values lie in the Schwartz class. The formulas clearly show the effect of the boundary on the solution. The approach is based on a nonlinear steepest descent analysis of an associated Riemann–Hilbert problem.
INTERNATIONAL JOURNAL OF RESEARCH SCIENCE & MANAGEMENT

Finance is a key input in the development and growth of business enterprise. One of the reasons why firms form linkages and relations with one another as well as with financial institutions is to access credit for business growth. Credit contributes to enterprises development in a number of ways. Access to external resources allows for flexibility in resource allocation and reduces the impact of cash flow problems on firm activity. Firms with access to funding are able to build up inventories to avoid stocking out in periods of crisis, while in conditions of macroeconomic instability, use of credit increases growth of surviving firms. It is founded from different results that business credibility availability has an impact on SMEs. The data for this study were purposely collected through the secondary sources and analyzed using content analysis approach. The major limitation of this research is that this study only covers the SMEs sector. Another limitation is that it excludes many variables of reward due to shortage of time. Funds were also another limitation. Apart from these limitations this research may provide insights to the managers of SMEs and Microfinance firms to make availability of funds to SMEs because they can boost the country’s economy and bring higher profit.
The Effect of Ophiocephalus striatus Extract on Quantitative Measurement of Biceps Brachii and Rectus Femoris in Patients with Mechanical Ventilation

Background. Population growth needs to be controlled so as not to cause new and serious problems. Pregnancy and birth control is a solution to control this sizable population growth. Contraception is a way to prevent pregnancy, by inhibiting the process of ovulation, fertilization and implantation. Nevertheless, most of contraceptive regiments were aimed to woman. Male contraception nowadays is very rare. Papaya seed is one of the male contraceptive candidates which has the potential to be developed as male contraception. Previous studies have shown the potential of papaya seed extract could reduce the weight of reproductive organs of male white rats, where it was believed that there was a decrease in spermatogenesis activity. Methods. This research was an in-vivo experimental research post-test only with control group. The study used 32 male and healthy rats (Rattus norvegicus) Wistar strain with 8-10 weeks of age. Rats were grouped into 1 control group and 4 treatment groups that were randomly selected. The four treatment groups were group 1: control administered 1% 2ml CMC orally one time per day every morning, group 2: were given N-hexane papaya seed fraction, group 3: were given ethyl acetate papaya seed fraction and group 4: were given ethanol-water papaya seed fraction. The three fractions were given to rats orally at a dose of 100 mg / KgBB / day for 24 days. After that, rat's testes and epidydimis were evacuated to observe reproductive organs and sperm quality. Results. Anatomically, Group 2 and 3 were statistically significant in reducing testicular's and epidydimis' weight compared to the control group, but the n-hexane group was more effective in reducing testicular weight than other treatment groups. Furthermore, groups 2, 3 and 4 were statistically significant in reducing sperm quality (motility, viability, amount of sperm cells and normal sperm cell morphology) compared to the control group, but the nhexane group was more effective in reducing sperm quality than other treatment groups. Conclusion. Papaya seed n-hexane fraction has potential as a male contraceptive by reducing spermatogenesis activity and decreasing sperm quality in white rats.
High-quality correspondence imaging based on sorting and compressive sensing technique

We propose a high-quality imaging method based on correspondence imaging (CI) using a sorting and compressive sensing (CS) technique. Unlike the traditional CI, the positive and negative (PN) subsets are created by a sorting method, and the image of an object is then recovered from the PN subsets using a CS technique. We compare the performance of the proposed method with different ghost imaging (GI) algorithms using the data from a single-detector computational GI system. The results demonstrate that our method enjoys excellent imaging and anti-interference capabilities, and can further reduce the measurement numbers compared with the direct use of CS in GI.

Unusual perpendicular anisotropy in Co2TiSi films

Thin films of Co2TiSi on MgO are investigated experimentally and theoretically. The films were produced by magnetron sputtering on MgO(0 0 1) and have a thickness of about 100 nm. As bulk Co2TiSi, they crystallize in the normal cubic Heusler (L21) structure, but the films are slightly distorted (c/a = 1.0014) and contain some antisite disorder. The films exhibit a robust perpendicular anisotropy of 0.5 MJ m−3. This result is surprising for several reasons. First, surface and interface anisotropies are too small to explain perpendicular anisotropy in such rather thick films. Second, Co2TiSi has a substantial magnetization and crystallizes in a cubic Heusler structure, so that conventional wisdom predicts a preferential magnetization direction in the film plane rather than perpendicular. Third, the lattice strain of 0.14% is unable to account for the perpendicular anisotropy. We explain the perpendicular anisotropy as a quasicubic symmetry breaking chemical-ordering effect promoted by the substrate.

A numerical analysis is carried out to study heat and mass transfer effects on MHD natural convection flow past an impulsively moving vertical plate with ramped temperature. The dimensionless governing momentum, energy and concentration equations for this investigation are solved numerically by using most flexible method which is finite element method. The effects of the various pertinent parameters entering into the problem on the velocity, temperature and the concentration profiles are illustrated graphically and discussed for both ramped temperature and isothermal plates. The effects of various parameters on the skin friction, Nusselt number and the Sherwood number are presented numerically in tabular form. Finally obtained numerical results are compared with the previously published results and are in quantitative agreement.
