 The Ces\'aro operator $\mathcal{C}_{\alpha}$ is defined by \begin{equation*} (\mathcal{C}_{\alpha}f)(x) = \int_{0}^{1}t^{-1}f\left( t^{-1}x \right)\alpha (1-t)^{\alpha -1}\,dt~, \end{equation*} where $f$ denotes a function on $\mathbb{R}$. In Vitro and In Vivo Characterization of Alpha-1A Selective Agonists and Their Utility for Stress Incontience Pseudorabies virus (PRV), an alpha-herpesvirus, has been developed as a live viral vector for animal vaccines. The effects of intracerebroventricular (icv) agonists and antagonists of N-methyl-D-aspartate (NMDA) and alpha-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid (AMPA) receptors on the general anesthesia of propofol were studied. The epitope structure of human alpha-fetoprotein (AFP) was studied using more than 50 monoclonal antibodies (MAB) to human AFP. 更多

 If is a ?2-grading of a simple Lie algebra, we explicitly describe a-module Spin0 () such that the exterior algebra of is the tensor square of this module times some power of 2. We prove that for any expansive n×n integral matrix A with |det A|=2, there exist A-dilation minimally supported frequency (MSF) wavelets that are associated with a multiresolution analysis (MRA). The same technique of proof is also applied to yield an existence result for A-dilation MRA subspace wavelets.

 Measurement of the intensity of total scattering of x-rays by a number of polyatomic gases was made for scattering angles between 15° and 130 ° using an ionization method of recording the scattered intensity. Balanced filters of ZrO2, and SrO were used to separate the MoKa rays and Soller slits were placed in front of the ionization chamber to obtain a definite scattering angle. The gases studied are CL2, CO2, N2O, H2S, CC14 and CHCl3. In each case the absolute values of the scattered intensity were determined... Measurement of the intensity of total scattering of x-rays by a number of polyatomic gases was made for scattering angles between 15° and 130 ° using an ionization method of recording the scattered intensity. Balanced filters of ZrO2, and SrO were used to separate the MoKa rays and Soller slits were placed in front of the ionization chamber to obtain a definite scattering angle. The gases studied are CL2, CO2, N2O, H2S, CC14 and CHCl3. In each case the absolute values of the scattered intensity were determined by comparison with the scattering from oxygen, the results of Wollan for the latter gas being taken as correct. The experimental results are actually compared with Woo's theory of the scattering of x-rays by polyatomic gases and the agreement seems to be satisfactory. 吴有训氏最近对于多原子气体散射线之理论,曾作详尽的探讨。吴氏得到一个公式,表示由多原子气体所散射之强度,其中一部为相干的散射,另一部为不相干的散射。 以前关于多原子气体散射X-线之实验,为数甚少,且为定性的结果。最近美人Wollan,对于由O_2及N_2(双原子气体)所散射钼的K_3α线之强度,曾作绝对的度量。Wollan的结果,与吴有训氏的理论,甚属相符。本篇目的,在测定由 Cl_2,CO_2,N_2O,H_2S,CCl_4及 CHCl六种气体所散射X-线之强度,每一实验,均与由0_2者互相比较,根据Wollan的结果,每种气体所散射之绝对强度,皆一一量得。所用之入射X-线为钼之Kα线,系藉Ross的平衡过滤法分出。强度之测量,系用一游离方法。散射角度的范围,自15度至130度。每种气体的实验结果,均与吴氏的理论,互相比较,证明理论与实验,甚属相符。在计算时,原子的“构造因数”,系由Hartree的方法算得,一分子中两原子的相隔距离,则由带光谱的结果推得。 The potential between two nucleons suggested by K. C. Wang, viz. 本篇应用王淦昌所建议之两个核子间之相互位能 即 V=V(r)=- Ae~(klr) 在r≥α时; 及V=V(α) 在r<α时。以求下列数点:(1)重子在正常情形时之波函数,(2)中子与质子间之扩散断面值,及(3)重子被γ射线击破之断面值。本篇所计算得之各断面值之结果与实验所得者,颇相近似。 The anhydro ring in a-methyl 2:3-anhydro-4:6-benzylidene-D-allopyranosidehas been opened by the action of sodium benzylate to give 53% yield ofα-methyl 2-benzyl-4:6-benzylidene-D-altropyranoside and 9% of a-methyl 3-benzyl-4:6-benzylidene-D-glucopyranoside.After the removal of the benzy-lidene residue by acid hydrolysis,the position of attachment of the benzylgroup is determined by periodate oxidation.Catalytic hydrogenolysis of thebenzyl group gives the known α-methyl D-altroside and a-methyl D-glucosiderespectively... The anhydro ring in a-methyl 2:3-anhydro-4:6-benzylidene-D-allopyranosidehas been opened by the action of sodium benzylate to give 53% yield ofα-methyl 2-benzyl-4:6-benzylidene-D-altropyranoside and 9% of a-methyl 3-benzyl-4:6-benzylidene-D-glucopyranoside.After the removal of the benzy-lidene residue by acid hydrolysis,the position of attachment of the benzylgroup is determined by periodate oxidation.Catalytic hydrogenolysis of thebenzyl group gives the known α-methyl D-altroside and a-methyl D-glucosiderespectively and their constitutions are thus proved.While an ethylene oxide ring in a sugar molecule can be opened by alkaline reagents,such as sodium hydroxide,sodium methoxide,ammonia,etc,the use of sodium benzylate has the advantage that one of the hydroxylgroups is protected after the scission by the benzyl group which can in turnbe removed by catalytic hydrogenation. 应用苯甲醇钠可以裂解α-甲基2∶3-内醚-4∶6-苯亚甲基-D-同侧醣氧六圜配醣物的醚环,生成53%的α-甲基2-苯甲基-4∶6-苯亚甲基-D-2-异侧醣氧六圜配醣物及9%的α-甲基3-苯甲基-4∶6-苯亚甲基-D-葡萄糖氧六圜配醣物。此两化合物的结构,应用水解除去苯亚甲基及接触氢解除去苯甲基后,证明是已知的α-甲基 D-2-异侧醣氧六圜配醣物,及α-甲基 D-葡萄糖氧六圜配醣物;苯甲基在醣分子中的衔接位置,则应用高碘酸钠氧化测定。 << 更多相关文摘
