In this paper we demonstrate the possibility of modifying porous silicon (PSi) particles with surface chemistry and recognition molecules (antibodies) such that these devices could potentially be used for single-cell identification or sensing. This is achieved by modifying PSi Rugate filters via hydrosilylation with surface chemistry that serves firstly, to protect the silicon surfaces from oxi...

Shade-establishing plants growing in the forest understory are exposed to constant high light or fluctuating light when gaps are created by fallen trees. Our previous studies indicate that photosystem I (PSI) is sensitive to constant high light in shade-establishing tree species, however, the effects of fluctuating light on PSI and photosystem II (PSII) in shade-establishing species are little ...

Let S0 = 0, {Sn, n ≥ 1} be a random walk generated by a sequence of i.i.d. random variables X1, X2, ... and let τ = min{n ≥ 1 : Sn ≤ 0} and τ = min{n ≥ 1 : Sn > 0}. Assuming that the distribution of X1 belongs to the domain of attraction of an α-stable law we study the asymptotic behavior, as n → ∞, of the local probabilities P(τ = n) and the conditional local probabilities P(Sn ∈ [x, x+∆)|τ > ...

Li & Racine (2008) consider the nonparametric estimation of conditional cumulative distribution functions (CDF) in the presence of discrete and continuous covariates along with the associated conditional quantile function. However, they did not propose an optimal data-driven method of bandwidth selection and left this important problem as an ‘open question’. In this paper we propose an automati...

The formation of pseudouridine (psi) in human U1, U2 and U5 small nuclear RNAs (snRNAs) was investigated using HeLa cell extracts. Unmodified snRNAs were synthesized in vitro and the extent of psi formation was determined after incubation in cell extracts. The formation of psi on labelled substrates was monitored in the presence of 5-fluorouracil (5-FU)-containing snRNAs as inhibitors of psi fo...

This paper addresses the problem of nonparametric estimation of the conditional expected shortfall (CES) which has gained popularity in financial risk management. We propose a new nonparametric estimator of the CES. The proposed estimator is defined as a conditional counterpart of the sample average estimator of the unconditional expected shortfall, where the empirical distribution function is ...

The paper considers various extended asymmetric multivariate conditional volatility models, and derives appropriate regularity conditions and associated asymptotic theory. This enables checking of internal consistency and allows valid statistical inferences to be drawn based on empirical estimation. For this purpose, we use an underlying vector random coefficient autoregressive process, for whi...

The cytoplasmic [PSI+] determinant of Saccharomyces cerevisiae is the prion form of the Sup35 protein. Oligopeptide repeats within the Sup35 N-terminal domain (PrD) presumably are required for the stable [PSI+] inheritance that in turn involves fragmentation of Sup35 polymers by the chaperone Hsp104. The nonsense suppressor [PSI+] phenotype can vary in efficiency probably due to different inher...

We study the asymptotic properties of the Shapley value of patent licensing games with the Cournot competition, shedding light on its relations to the nucleolus, core and bargaining set. The Shapley value of the outside patentee of a non-drastic cost-reducing innovation converges to 2(a − c), which coincides with the patentee’s profit through non-cooperative licensing by means of upfront fee (o...

In this paper, we study the asymptotic normality of the conditional maximum likelihood (ML) estimators for the truncated regression model and the Tobit model. We show that under the general setting assumed in his book, the conjectures made by Hayashi (2000) 1 about the asymptotic normality of the conditional ML estimators for both models are true, namely, a sufficient condition is the nonsingul...
