Letter from L. P. Schaefer to L. De Bona requesting miscellaneous goods.
No full textLeonard de Bona was a businessman, possibly of Italian descent, in Eagle Pass, Texas, who ran a hardware and supply store in that area for nearly 20 years. He served as a point of contact for customers throughout South Texas and nearby Mexico, providing not only hardware but food, clothing, and sundries. He had business contacts in San Antonio, Chicago, and abroad (Central Mexico, Italy, and other locations.)Archive of Correspondence relating to L. de Bona's Eagle Pass Hardware and Supply Store from 1887-1903 and undated.

FiFoSiM - an integrated tax benefit microsimulation and CGE model for Germany
No full textThis paper describes FiFoSiM, the integrated tax benefit microsimulation and computable general equilibrium (CGE) model of the Center of Public Economics at the University of Cologne. FiFoSiM consists of three main parts. The first part is a static tax benefit microsimulation module. The second part adds a behavioural component to the model; an econometrically estimated labour supply model. The third module is a CGE model which allows the user of FiFoSiM to assess the global economic effects of policy measures. Two specific features distinguish FiFoSiM from other tax benefit models: First, the simultaneous use of two databases for the tax benefit module and second, the linkage of the tax benefit model to a CGE model.FiFoSiM; microsimulation; CGE
The L-p-to-L-q boundedness of commutators with applications to the Jacobian operator
No full textSupplying the missing necessary conditions, we complete the characterisation of the L-p -> L-q boundedness of commutators [b, T] of pointwise multiplication and Calderon-Zygmund operators, for arbitrary pairs of 1 q, our results are new even for special classical operators with smooth kernels. As an application, we show that every f is an element of L-p(R-d) can be represented as a convergent series of normalised Jacobians J(u) = det del uof u is an element of (over dot(W))(1,dp)(R-d)(d). This extends, from p = 1 to p > 1, a result of Coifman, Lions, Meyer and Semmes about J:. (over dot(W))(1,d)(R-d)(d) -> H-1(R-d), and supports a conjecture of Iwaniec about the solvability of the equation Ju = f is an element of L-p(R-d). (C) 2021 The Author(s).

New records of plants fed upon by the uncommon Heteropterans Cyrtocoris egeris Packauskas & Schaefer and C. trigonus (Germar) (Hemiptera: Cyrtocoridae) in South America.
No full textDuring March 2000, nymphs and adults of the cyrtocorid bugs Cyrtocoris egeris Packauskas & Schaefer and C. trigonus (Germar) were observed on two different plants at two different localities. In Brazil (Londrina, Paraná State) adult C. trigonus were found feeding on stems of the weed plant arrow leaf sida, Sida rhombifolia L. (Malvaceae). Despite egg deposition in the laboratory, nymphs did not develop on this plant. In Argentina (Reconquista, Santa Fé Province), nymphs and adults of C. egeris were observed feeding on immature soybean [Glycine max (L.) Merrill] pods. Under laboratory conditions, nymphs of neither species could be reared beyond the third instar
Semiinclusive polarized lepton nucleon scattering and the anomalous gluon contribution
No full textWe discuss a new observable for semi-inclusive pion production in polarised lepton-nucleon collisions. This observable is sensitive to the polarised and unpolarised strange quark distribution and the anomalous gluon contribution, provided that their fragmentation functions into pions differ substantially from that of light quarks. From Monte Carlo data generated with our PEPSI code we conclude that HERMES might be able to decide whether the polarized strange quark and gluon distributions are large
Common components in perception and imagery of music:an EEG study
No full textMental imagery has been a subject of investigation for a considerable time. Recent investigations suggest that there is overlap in the electrical brain activations for imagination and perception of music (Schaefer et al., 2009, 2011a; Vlek et al., 2011). The current work is a new analysis of four datasets that investigate imagination of music, aiming to clarify the common processes in perception and imagination of music for stimuli of varying complexity. These studies, using electroencephalography (EEG), look at various aspects of music, namely rhythmic accents, monophonic melodies, more complex rhythms or natural music stimuli. By decomposing the event-related EEG data, widely differing datasets may be investigated using the same analysis method. We first used Principal Component Analysis (PCA), and expanded on this method using PARAFAC tensor decomposition, which allows to add the task into the decomposition, but does not make assumptions of independence or orthogonality, and calculate the relative strengths of the identified components for each task
Thermal stability of lysozyme Langmuir-Schaefer films by FTIR spectroscopy
No full textFourier transform infrared spectroscopy has been applied to study the thermal stability of multilayer Langmuir-
Schaefer (LS) films of lysozyme deposited on silicon substrates. The study has confirmed previous structural findings
that the LS protein films have a high thermal stability that is extended in a lysozyme multilayer up to 200 °C. 2D
infrared analysis has been used here to identify the correlated molecular species during thermal denaturation. Asynchronous
2D spectra have shown that the two components of water, fully and not fully hydrogen bonded, in the high-wavenumber
range (2800-3600 cm-1) are negatively correlated with the amine stretching band at 3300 cm-1. On the grounds of
the 2D spectra the FTIR spectra have been deconvoluted using three main components, two for water and one for
the amine. This analysis has shown that, at the first drying stage, up to 100 °C, only the water that is not fully hydrogen
bonded is removed. Moreover, the amine intensity band does not change up to 200 °C, the temperature at which the
structural stability of the multilayer lysozyme films ceases
