The fission cross section for 237NP from a b o u t 1 eV to about 5 keV r e l a t i v e t o t h a t for 235U was measured with back–to–back type double fission chambers using an elec– tron linear accelerator (linac) driven lead slowing–down neutron spectrometer (lead spectrometer) . Although the shape of the present energy dependent cross section agrees with those of JENDL–3 (below 120 eV) and E...

We present the cross section for pair production of scalar leptoquarks LQ in p¯ p collisions, p + ¯ p → LQ + LQ + X, at the Fermilab Tevatron in next-to-leading order QCD. Including the higher-order corrections stabilizes the theoretical prediction and increases the size of the cross section for renormalization/factorization scales close to the mass of the leptoquarks. This leads to an increase...

In AD, a significant synaptic loss ranging from 20% to 50% is reported. Biochemistry, elec‐ tron microscopy and immunocytochemistry have shown a decrease in synaptic density, presynaptic terminals, synaptic vesicle and synaptic protein markers in AD brains com‐ pared with the normal aged controls (Terry et al., 1991; Geula, 1998; Larson et al., 1999; Yao et al., 1999; Ashe, 2000; Baloyannis et ...

We present the first measurements of σ(p¯ p → W → ℓν) and σ(p¯ p → Z → ℓℓ) at √ s = 1.96 TeV, along with new measurements of W angular-decay distributions in p¯ p collisions at √ s = 1.8 TeV. W and Z boson production cross-section measurements in p¯ p collisions are a test of the consistency of Standard-Model couplings, constrain proton parton distribution functions, and provide information on ...

This study examines the volatility of nine leading cryptocurrencies by market capitalization—Bitcoin, XRP, Ethereum, Bitcoin Cash, Stellar, Litecoin, TRON, Cardano, and IOTA-by using a Bayesian Stochastic Volatility (SV) model several GARCH models. We find that when we deal with extremely volatile financial data, such as cryptocurrencies, SV performs better than family Moreover, forecasting err...

Pulsar nebula supernova remnant and nu cleus of active galaxy are found as TeV gamma ray emit ter and the number of such sources is now approaching All of them so far evidenced are explained by electron progenitor The emission process in the TeV energy region is characterized and controlled by the particle interaction of high energy photons and electrons The radiation by electrons implies a tig...

Rheological and microstructural changes that occurred in ropy yogurt during shearing were ob served. Yogurt made with an exopolymer-producing (ropy) strain of Lactobacillus delbrueckii subsp. bulgaricfui and non ropy s tram of Streptococcus thermop us was subjected to an increas1ng shear rate from 0-833 s 1 using a Haake Rotavisco RV2. Shear stress noticeably increased to a peak value and then ...

In developing Clostridium perfringens as a safe vaccine vector, the alpha toxin gene (plc) in the bacterial chromosome must be permanently inactivated. Disrupting genes in C. perfringens by traditional mutagenesis methods is very difficult. Therefore, we developed a new strategy using group II intron-based Target-Tron technology to inactivate the plc gene in C. perfringens ATCC 3624. Western bl...

One of the communication tools of the EC-funded Biosafenet project is a series of six Biosafenet Seminars that will be held 2007–2009. Their purpose is to convene small groups of scientists to consider emerging issues related to the potential impact of genetically modified organisms (GMOs). The first Seminar was organized by the ICGEB at the MasterCampus of the Fondazione Cassamarca in Ca’ Tron...
