Published: October 2012

AbstractPrevious studies have shown that self‐generated information is better remembered than information that has been read passively. To further examine this subsequent memory effect, we investigated the effect of five different linguistic relationships on memory encoding. Ninety subjects were administered 60 paired associates during an encoding condition: 30 of the second words from each pair were to be read aloud and 30 were to be self‐generated from clues as to the correct word. Word pairs were composed of five linguistic relationships: category, rhyme, opposite, synonym, and association. Subsequently, subjects were presented with the words that were read or generated in a forced recognition memory task. Overall, reading accuracy was higher than generation accuracy during the encoding phase (all P < 0.001). During the recognition phase, subjects' performance was better on the generate than on the read conditions for opposite, synonym, category, and association relationships (all P < 0.05), with no difference in the rhyme relationship. These results confirm previous findings that self‐generated information is better remembered than read information and suggest that this advantage may be mediated by using opposite, synonym, category, and association relationships, while rhyme relationship may not extend such an advantage. These findings may have implications for future studies of memory interventions in healthy controls and subjects with cognitive impairments.

Published: October 2012

AbstractFormation of a gas hydrate with two different gas compositions (natural gas and a mixture of methane‐ethane‐propane) was investigated using a special method of producing the hydrate from ice. Gas uptake, splitting the fraction of each component between the gas phase and hydrate phase, and purification of methane were studied in the presence of silica‐based porous media. Addition of a small amount of colloidal silica media increased considerably the gas storage capacity of the hydrate phase. In the presence of silica‐based porous media, the purification factor of CH4 became significantly higher. The results can provide the basis for the storage of natural gas in hydrate form and application of the hydrate‐based gas separation technology to achieve methane with high purity from natural gas.
High‐Precision Power Measurement for the Grindability Test According to Zeisel
Authors: Fleiger P. M. , Reichardt R. , Treiber K. 
Published: October 2012

AbstractAlthough established in the 1950s, the grindability test according to Zeisel is still one of the most important measurement techniques for the grindability of hard and brittle material. It is used intensively throughout the cement industry for testing clinker and slag, but also for limestone. Test results are applied for mill designing or capacity estimations and often form the basis for contracts for grinding equipment. The accuracy of the test strongly depends on the test parameters but also on the reliability of the employed measurement techniques. Although of high importance to the industry, these measurement techniques are not state‐of‐the‐art. The precise measurement of grinding work by a load cell is introduced which replaces measurement by deflection and protractor.
Turn‐On Fluorescence Sensor Based on Single‐Walled‐Carbon‐Nanohorn–Peptide Complex for the Detection of Thrombin

Published: October 2012

AbstractProteases play a central role in several widespread diseases. Thus, there is a great need for the fast and sensitive detection of various proteolytic enzymes. Herein, we have developed a carbon nanotube (CNT)‐based protease biosensing platform that uses peptides as a fluorescence probe for the first time. Single‐walled carbon nanohorns (SWCNHs) and thrombin were used to demonstrate this detection strategy. SWCNHs can adsorb a fluorescein‐based dye (FAM)‐labeled peptide (FAM‐pep) and quench the fluorescence of FAM. In contrast, thrombin can cleave FAM‐pep on SWCNHs and recover the fluorescence of FAM, which allows the sensitive detection of thrombin. This biosensor has a high sensitivity and selectivity toward thrombin, with a detection limit of 100 pM.

Specifying subtypes in Safety Critical Java programs
Authors: Haddad Ghaith , Leavens Gary T. 
Published: October 2012

SUMMARYReal‐time and safety‐critical code could benefit from the use of design patterns and frameworks that rely on subtyping and dynamic dispatch. However, modular reasoning about programs that use subtypes requires that each overriding method obeys the specifications of all methods that it overrides. For example, if method scale is specified in a supertype Vector2d to take at most 42 ns to execute, then an override of scale cannot take more than 42 ns to execute in any subtype, such as Vector3d. The problem is that subtype objects typically contain more information, such as the z coordinate in Vector3d, and thus their methods often require more time to execute than the methods they override. In this paper, we show how to specify timing constraints for subtypes in a way that both allows overriding subtype methods to have more time to execute and yet permits precise modular verification and checking of timing constraints. Our techniques allow object‐oriented coding and design patterns based on subtype polymorphism to be used in real‐time and safety‐critical software. Copyright © 2012 John Wiley & Sons, Ltd.
Substituent Effects on Photosensitized Splitting of Thymine Cyclobutane Dimer by an Attached Indole
Authors: Tang Wenjian , Zhou Hongmei , Wang Jing , Pan Chunxiao , Shi Jingbo , Song Qinhua 
Published: October 2012

AbstractIn chromophore‐containing cyclobutane pyrimidine dimer (CPD) model systems, solvent effects on the splitting efficiency may depend on the length of the linker, the molecular conformation, and the oxidation potential of the donor. To further explore the relationship between chromophore structure and splitting efficiency, we prepared a series of substituted indole–T<>T model compounds 2 a–2 g and measured their splitting quantum yields in various solvents. Two reverse solvent effects were observed: an increase in splitting efficiency in solvents of lower polarity for models 2 a–2 d with an electron‐donating group (EDG), and vice versa for models 2 e–2 g with an electron‐withdrawing group (EWG). According to the Hammett equation, the negative value of the slope of the Hammett plot indicates that the indole moiety during the T<>T‐splitting reaction loses negative charge, and the larger negative value implies that the repair reaction is more sensitive to substituent effects in low‐polarity solvents. The EDGs of the models 2 a–2 d can delocalize the charge‐separated state, and low‐polarity solvents make it more stable, which leads to higher splitting efficiency in low‐polarity solvents. Conversely, the EWGs of models 2 e–2 g favor destabilization of the charge‐separated state, and high‐polarity solvents decrease the destabilization and hence lead to more efficient splitting in high‐polarity solvents.
A distributed mobility management scheme in networks with the locator/identifier separation
Authors: Qiu Feng , Zhou HuaChun , Li Xiaoqian , Wang Gongpu , Zhang Hongke 
Published: October 2012

SUMMARYIn traditional Internet architectures, current centralized mobility management schemes face scalability issues because of the creation of network bottlenecks and a single mobility agent of failures. To address these issues, we propose a distributed mobility management scheme in locator/identifier separation networks (DMMLIS). We divide the network into many domains according to the area of autonomous systems. Each domain consists of a mapping server and several tunnel routers (xTRs). The mapping server stores global mappings between endpoint identifier (EID) prefixes and autonomous system numbers (ASNs) to lookup the mobile nodes' (MNs') home domain. Meanwhile, the mapping server also contains ASN‐to‐xTR mappings so that it can forward Map‐Register and Map‐Request messages to any xTR of the MN's home domain, thus enhancing reliability. In addition, the xTRs in each domain constitute one‐hop distributed hash table ring. Moreover, any xTR in the MN's home domain may be the home agent of MNs, and the MNs' EID‐to‐RLOC (routing locator) mapping is stored in two xTRs using two hash functions. In this way, it not only supports quick lookup but also improves scalability and survivability. To evaluate the survivability and the efficiency of DMMLIS, we analyze the service blocking probability, the system response time, and the total protocol cost. We also present numerical results to demonstrate the performance of the proposed scheme. Copyright © 2012 John Wiley & Sons, Ltd.
How does a newly born mouse get to the nipple? odor substrates eliciting first nipple grasping and sucking responses
Authors: Al Aïn Syrina , Belin Laurine , Schaal Benoist , Patris Bruno 
Published: October 2012

AbstractIt is a mammalian female strategy to emit odor cues and signals that direct their inexperienced newborns to the nipple, and optimize their initial sucking success and, hence, viability. Here, natural odorous substrates that contribute to nipple grasping were investigated in mice, a species that has not been much scrutinized on this topic. The response of pups toward the nipples of lactating females (LF) versus nonlactating females (NLF) were first assessed right after watched birth, before and after the first suckling experience, and at 1 day old, after more extended suckling experience. It appeared that only nipples of LF induced grasping at these early ages, leading to take NLF as the baseline setting to present various odor substrates sampled from LF, viz. amniotic fluid, murine milk, LF saliva, pup saliva, LF urine, and an odorless control stimulus (water). Results indicate that: (1) only amniotic fluid and fresh milk induced nipple grasping before the first suckling experience; (2) LF saliva started inducing grasping after the first suckling experience; (3) pup saliva released grasping after 24–36 hr of suckling experience; finally (4) neither LF urine, nor water induced any nipple grasping. In conclusion, the activity of amniotic fluid and murine milk on neonatal pup behavior before any postnatal suckling experience suggests that either prenatal learning and/or predisposed olfactory mechanisms do operate, while the behavioral activation due to maternal and infantile salivas clearly depends on postnatal exposure. © 2012 Wiley Periodicals, Inc.

The Influence of Arylene and Alkylene Units on the Structuring of Urea‐Based Bridged Silsesquioxanes
Authors: Pichon Benoît P. , Scampini Sylvana , Bied Catherine , Moreau Joël J. E. , Wong Chi Man Michel 
Published: October 2012

AbstractThe influence of the intrinsic self‐assembling properties of rigid or semirigid aromatic units as the main substructures combined with the effect of the alkylene side chains as linkers on the nanostructure of bridged silsesquioxanes was studied. The symmetry of the organic units was found to control the dimensionality of the hybrid nanostructure. Bis(silylated) aromatic units lead to lamellar hybrids, whereas tris(silylated) aromatic units tend to form hexagonal structures. The ordering of each type of structure depends directly on the conformation of the organic units, which determines the self‐assembling of precursors through intermolecular interactions.
