S.R. Lewis letter to Z. Eastman, March 5, 1874
Brief letter from S.R. Lewis to Z. Eastman, marking the announcement of an abolitionists' reunion to be held in Chicago in June of 1875. Lewis requests that Eastman, given his close acquaintance with Benjamin Lundy, prepare a public statement of remembrance on Lundy and his contributions to the anti-slavery movement. Benjamin Lundy (1789-1839) was a prominent Quaker abolitionist best known for his development of abolitionist periodicals. His Genius of Universal Emancipation was first published in 1821 from his home in Mt. Pleasant, Ohio, and enjoyed a wide circulation across the antebellum United States. In the 1820s, the young William Lloyd Garrison came to work for The Genius. Benjamin Lundy traveled widely seeking subscriptions to The Genius, giving talks about the anti-slavery movement, and observing and documenting the conditions of enslaved people across the Americas. He was also involved in the establishment of freed slave colonies in Mexico
Modelling and optimization of a permanent-magnet machine in a flywheel
This thesis describes the derivation of an analytical model for the design and optimization of a permanent-magnet machine for use in an energy storage flywheel. A prototype of this flywheel is to be used as the peak-power unit in a hybrid electric city bus. The thesis starts by showing the feasibility of using a flywheel energy storage system for this application, as opposed to other energy storage technologies. It then continues by describing a prototype flywheel system and the required electrical machine: a radial-flux external-rotor permanent-magnet synchronous machine without slots in the stator iron and with a shielding cylinder. An analytical model for the machine is derived, based on 2D electromagnetic field calculations, including the reaction field of the eddy currents in the shielding cylinder. Torque and losses are calculated by means of the Theorem of Poynting and the Lorentz force. Such a machine was built and the analytical model has been validated by experimental measurements. Lastly, the thesis suggests and implements a machine optimization algorithm.Information Technology and System
Jacob accumulates in the nucleus after LTP induction.
<p>A) The diagram shows averaged normalized fEPSP-slope values over time. LTP was induced by 3 trains of 100 Hz/1-s tetanization (arrows) at 10-min intervals. Slices were collected 40 minutes after the last baseline recording. The fEPSP transients are depicted for the time points as indicated by black and gray filled circles. B) For the conditions ‘Ketamine no incubation’, ‘incubation' and ‘LTP’ representative digital images of Jacob immunofluorescence are presented. Under control conditions Jacob is localized in proximal apical dendrites and is enriched at the nuclear membranes of CA1 neurons. After LTP induction the immunofluorescence in the str. pyramidale (s.p.) is more intense whereas the fluorescence signal is reduced in the str. radiatum (s.r.) area. The white boxes represent region of interests (ROIs) taken for the measurement of averaged intensities within the s.p. and s.r. field. Higher magnification images of s.p. are presented (scale bar: 10 µm). C) The diagram depicts the results of the quantitative analyses of the immunofluorescence under the various conditions. The ratio of s.p. to s.r. was calculated after subtracting background values (b; minimum value in dendritic area) from the averaged fluorescence intensity of s.r. (Fd: dendritic fluorescence) and s.p. (Fs: somatic fluorescence). After LTP induction the ratio is significant larger than the ratio from “incubation after Ketamine” slices. The inlet summarizes the design of the experiment.</p
Design metrics for evaluating the propulsive efficiency of future ships
There is an increasing need for the ship design process to take account of environmental issues such as the emission of greenhouse gases and the likely extension of a carbon dioxide charging mechanism to international shipping. These issues, together with the need for economic viability, provide further incentives to improve the efficiency of propulsion of ships. The main components of powering are firstly reviewed. Individual components and other power saving devices are identified which should contribute to improvements in the overall efficiency of propulsion. Suitable design metrics and procedures, taking into account economic and environmental factors, are recommended for the design of future ships

The Jacob distribution remains unaltered after LTD induction.
<p>A) Averaged normalized fEPSP-slope values (black filled diamonds) are shown. fEPSP-slope values during LTD induction (horizontal black bar) are depicted as gray dots. LTD was induced by 900 bursts and one burst consists of 3 stimuli at an inter-stimulus interval of 50 ms. The color of the fEPSP-transients in the left inlet corresponds to time points indicted by the respective black, light gray and dark gray filled circles. The second inlet shows fEPSPs of an initial burst during LTD induction. Slices for the immunohistological analysis of Jacob translocation were taken 40 minutes after the last baseline recording. B) Representative digital fluorescence images of Jacob immunofluorescence for the conditions “no LTD” and “LTD” are presented. The white boxes indicate ROIs taken for the measurement of averaged intensities within the s.p. and s.r. field. The white horizontal bar represents 10 µm. C) The bar diagram summarizes the immunofluorescence analyses of hippocampal slices without (black) and with LTD (dark gray) induction. The ratio of s.p. to s.r. was calculated after subtracting background values (b; minimum value in dendritic area) from the averaged fluorescence intensity of s.r. (Fd: dendritic fluorescence) and s.p. (Fs: somatic fluorescence). After LTD induction the ratio was not different from the ratio of “no LTD” slices. The inlet indicates the time for the various activities.</p
The theme of 'blessing for the nations' in the patriarchal narratives of genesis.
The universalistic promise expressed by a formula with the theme
"Blessing for the Nations" in the Old Testament is primarily
found in the patriarchal narratives (Gen. l2-35). This aspect
of the patriarchal narratives however has not been adequately
studied. Previous discussions of the theme, based primarily
on 12:1-3, and conducted within the framework of the Yahwist's
work, are shown to be inadequate in our survey in shedding light
on the positioning and significance of the theme in the overall
patriarchal narratives. The survey indicates a literary analysis
of these narratives could probably yield more positive results.
2. A. formulaic analysis shows that the niphal form is
used at the beginning of a
patriarchs career to express a
probationary, and the hithpael form to express a
reaffirmatory, relationship of the patriarch to the promised
universal destiny. Strikingly, the 'seed' plays a prominent
role in the destiny. The formula also serves to link the
patriarchs' calling to the primeval history and the history of
the early formative period of the Israelite people.
3. The Abraham story (Gen.12-.22) is encased by the theme. A
double-chiastic arrangement of the narratives (in two groups)
shows a movement of horizon from the particularistic to the
universalistic. The universal horizon of Abraham's initial call
(12:1-3), displaced in the first half of the structure, is
reaffirmed in the latter half. Gen. l6 stands out as the nadir
and turning-point of the overall story. The notices of Isaac's
birth are instructively "positioned' in the universalistic
sector of the double-chiasmus. Moreover, the formula is
pronounced in narratives which portray Abraham as reversing the
negative results of the key events in the primeval history.
4. The Isaac narrative (Gen. 26) is shown to be "demonstration-material" of the initial actualisation of the theme. The
narrative is coherently structured around an emphatic divine
command, a unique twin-promise, and Isaac's response in a series
of movements, climaxing in Abimelech's sudden visit to and
significant confession of Isaac's status. Gen.26 is also
shown to be a "quintessence" of the Abraham story and forms a
critique of and model for Jacob's understanding and actualisation of his destiny.
5. The theme is shown to underline the Jacob story (Gen.25-35),
especially in the Jacob-.Esau cycles. Jacob's character transformation and reconciliation with Esau are necessary pre-requisites
before the reaffirmation' of the universal destiny to him at
Bethel. Significantly, the creation mandate is re-issued to
Jacob-Israel the seed of Abraham and Isaac, when a. formula
pronouncement is expected.. Finally, Jacob-Israel is shown to
form a parallel with Abraham whose call also expresses Yahwehs
re-affirmation of his creational intentions for mankind

Toward more efficient heuristic construction of Boolean functions
Boolean functions have numerous applications in domains as diverse as coding theory, cryptography,and telecommunications. Heuristics play an important role in the construction of Boolean functions with the desired properties for a specific purpose. However, there are only sparse results trying to understand the problem’s difficulty. With this work, we aim to address this issue. We conduct a fitness landscape analysis based on Local Optima Networks (LONs) and investigate the influence of different optimization criteria and variation operators. We observe that the naive fitness formulation results in the largest networks of local optima with disconnected components. Also, the combination of variation operators can both increase or decrease the network size. Most importantly, we observe correlations of local optima’s fitness, their degrees of interconnection, and the sizes of the respective basins of attraction. This can be exploited to restart algorithms dynamically and influence the degree of perturbation of the current best solution when restarting.Domagoj Jakobovic, Stjepan Picek, Marcella S.R.
