    Details
    Publication Date: 2024-04-05
    Description: Environmental stress factors negatively affect plant growth by inducing proteins dysfunction. As coping strategies, plant have developed a comprehensive protein quality controlling system (PQCS) to keep proteins homeostasis. In this research topic of “Protein Quality Controlling Systems in Plant Responses to Environmental Stresses”, some latest researches and opinions in this field, including heat shock proteins (HSPs), unfolded protein response (UPR), ubiquitin-proteasome system (UPS) and autophagy, were reported, aiming to provide novel insights for increasing crop production under environmental challenges.

    Influence of electrical stress voltage on cathode degradation of organic light-emitting devices (2001)
    [S.l.] : American Institute of Physics (AIP)

    Notes: Our in situ experimental observations of the influence of electrical stress voltage on organic light-emitting device growth in dark spot areas are presented. We demonstrate the use of microsized silica particles to create uniformly sized defects on the protective layer. This is an efficient way to control the location and the number of dark spots. The growth in dark spot area was studied at different driving voltages from 0 up to 11 V. Dark field microscopy was used to monitor the dark spot size below the turn-on voltage. The bright field was used at or above the turn-on voltage. Our observations indicate that dark spot growth was strongly affected by the electrical stress voltage. A linear growth rate with respect to the voltage was observed with a fitting parameter better than 99.7% when the device is driven above the turn-on voltage. We interpret the dark spot growth in terms of the diffusion of moisture and oxygen accompanied by cathode layer chemical and physical changes. © 2001 American Institute of Physics.

    The rotational spectrum of trans-HOCO and DOCO (1992)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: Part of the rotational spectrum of the hydroxyformyl radical, HOCO, and its deuterated analog has been detected at frequencies between 230 and 300 GHz. The radical was formed in a flow system by the reaction between chlorine atoms and formic acid. Analysis of the spectra yields reliable estimates of the rotational, centrifugal distortion and spin–rotational parameters describing the ground state of this species. The rotational constants derived for HOCO and DOCO are consistent with a planar equilibrium structure and are used to confirm that the carrier of the spectrum is the trans-geometrical isomer.

    Topics: Mathematics
    Notes: Abstract Letf be analytic in a hyperbolic region Ω. The Bloch constantβ f off is defined by $$\beta _f = \mathop {\sup }\limits_{z \in \Omega } |f'(z)|/\lambda _\Omega (z)$$ , where λΩ(z)|dz| is the Poincaré metric in Ω. Suppose Δ is hyperbolic and $$\mathop {\lim \inf }\limits_{\omega \to c} \lambda _\Delta (w) 〉 \lambda (\Delta ) 〉 0,\forall c \in \partial \Delta$$ where $$\lambda (\Delta ) = \mathop {inf}\limits_{w \in \Delta } \lambda _\Delta (w)$$ . Then for allf withf(Ω) ⊑Δ, we haveβ f ≤ 1/λ(Δ). In this paper we study the extremal functions defined byβ f =1/λ(Δ) and the existence of those functions.

    Springer
    Archive of applied mechanics 70 (2000), S. 366-376 
    Details
    ISSN: 1432-0681
    Keywords: Key words U-shaped bellows, integral equation method, nonlinear deformation, circular ring shell, shallow shell
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Summary The nonlinear integral equations for a U-shaped bellows with compressed angle and varying wall-thickness are derived according to the simplified Reissner theory of large deflection for revolution shells and integral-equation method. The iteration procedure for nonlinear analysis is developed by means of the integral equation iteration in conjunction with the gradient method. Numerical solutions for a U-shaped bellows under the action of axial compression force and internal pressure are obtained, which are compared with previous theories and experiments. The present results are shown to have a good accuracy, and may be applied directly to the design of bellows.

    Notes: Abstract The value method which is used to obtain the periodic solution to nonlinear system is mentioned in this article. Different point reflection is defined in the nonlinear autonomous and nonautonomous system firstly and then that linear reflection obtained from the inserting value of nonlinear reflection is asymptotic to original nonlinear reflection. The stationary points obtained by linear reflection are regarded as the asymptotic solution of the stationary points of original system. If this asymptotic solution of the stationary points is not satisfactorily accurate it can be used as the initial point of the next reflection. In addition, a corresponding method of researching the stability of periodic solution is put forward in this article.

    Notes: Abstract The matrix perturbation method is extended to discrete linear nonconservative system with unsymmetrical matrices in this article. By introducing the concept of the adjoint complex eigenvector and by making use of the orthogonality relationship in the complex mode theory, the first-order perturbation solution to the complex eigenvalues is derived. Numerical example shows that this method is efficient and practicable.

    Enhanced renoprotective effect of HIF-1α modified human adipose-derived stem cells on cisplatin-induced acute kidney injury in vivo (2015)
    Springer Nature
    Details
    Publication Date: 2015-06-06
    Description: Current therapeutic options for acute kidney injury (AKI) are limited to the use of supportive measures and dialysis. A recent approach that has sparked great interest and gained enormous popularity is the implantation of stem cells to repair acutely damaged kidney organ. Hypoxia inducible factor-1α (HIF-1α) is effective in protecting the kidney from ischemia and nephrotoxicity. In this study, we investigated whether HIF-1α-modified adipose-derived stem cells (ASCs) had an enhanced protective effect on cisplatin-induced kidney injury in vivo. Cisplatin-induced AKI was established in nude mice. Our study demonstrated that HIF-1α-modified ASCs obviously promoted the recovery of renal function, ameliorated the extent of histologic injury and reduced renal apoptosis and inflammation, but HIF-1α-modified ASCs homed to kidney tissues at very low levels after transplantation. In addition, we also found that HIF-1α-modified ASCs significantly increased HO-1 expression in cisplatin-induced AKI in vivo. Thus, our study indicated HIF-1α-modified ASCs implantation could provide advanced benefits in the protection again AKI, which will contribute to developing a new therapeutic strategy for the treatment of AKI.

    Reconstruction of palaeotopography from low-temperature thermochronological data (2009)
    In:  Geological Society Special Publication 324: 99-110.
    Details
    Publication Date: 2009-10-06
    Description: Thermochronology can provide information on palaeotopography and its evolution. We present a new method to reconstruct the shape of the palaeotopography from the palaeoisotherm derived from low-temperature thermochronological data. While deriving palaeoisotherm and reconstructing palaeotopography, the exhumation rate may also be constrained. The proposed method is independent of the relationship between the ancient and modern topography; however, it requires that the palaeotopography maintains its shape and the subsurface thermal field is invariant with time during the period when a set of samples passed through the closure temperature. It is shown that the inherent uncertainties in sample age and the limited sampling density will inevitably induce errors in the reconstructed topography, and these errors can be reduced by eliminating the noise in the derived isotherm. Increasing the number of samples helps to reduce the noise, and if, before sampling, we can make rough estimates about the geothermal gradient, the exhumation rate, the uncertainties in sample age, and the wave components and the relief of the palaeotopography to be reconstructed, the number of samples can be tentatively decided. It is also shown that the reconstructed topography is sensitive to exhumation rate and geothermal gradient, and a concrete sensitivity analysis is needed for a given dataset. By reinterpreting the (U-Th)/He data from the Sierra Nevada, California, we show that our method can reveal palaeorelief as well as other valuable information on the palaeotopography of the studied area.
