AbstractGermanosilicate zeolites often suffer from low hydrothermal stability due to the high content of Ge. Herein, we investigated the post‐synthesis introduction of Al accompanied by stabilization of selected germanosilicates by degermanation/alumination treatments. The influence of chemical composition and topology of parent germanosilicate zeolites (ITH, IWW, and UTL) on the post‐synthesis incorporation of Al was studied. Alumination of ITH (Si/Ge=2–13) and IWW (Si/Ge=3–7) zeolites resulted in the partial substitution of Ge for Al (up to 80 %), which was enhanced with a decrease of Ge content in the parent zeolite. In contrast, in extra‐large pore zeolite UTL (Si/Ge=4–6) the hydrolysis of the interlayer Ge−O bonds dominated over substitution. The stabilization of zeolite UTL was achieved using a novel two‐step degermanation/alumination procedure by the partial post‐synthesis substitution of Ge for Si followed by alumination. This new method of stabilization and incorporation of strong acid sites may extend the utilization of germanosilicate zeolites, which has been until now been limited.

AbstractTreatment of [M2(μ‐Cl)2(cod)2] (M=Ir and Rh) with Na[H2B(bt)2] (cod=1,5‐cyclooctadiene and bt=2‐mercaptobenzothiazolyl) at low temperature led to the formation of dimetallaheterocycles [(Mcod)2(bt)2], 1 and 2 (1: M=Ir and 2: M=Rh) and a borate complex [Rh(cod){κ2‐S,S′‐H2B(bt)2}], 3. Compounds 1 and 2 are structurally characterized metal analogues of 1,5‐cyclooctadiene. Metal–metal bond distances of 3.6195(9) Å in 1 and 3.6749(9) Å in 2 are too long to consider as bonding. In an attempt to generate the Ru analogue of 1 and 2, that is [(Rucod)2(bt)2], we have carried out the reaction of [Ru(Cl)2(cod)(CH3CN)2] with Na[H2B(bt)2]. Interestingly, the reaction yielded agostic complexes [Ru(cod)L{κ3‐H,S,S′‐H2B(bt)2}], 4 and 5 (4: L=Cl; 5: L=C7H4NS2). One of the key differences between 4 and 5 is the presence of different ancillary ligands at the metal center. The natural bond orbital (NBO) analysis of 1 and 2 shows that there is four lone pairs of electrons on each metal center with a significant amount of d character. Furthermore, the electronic structures and the bonding of these complexes have been established on the ground of quantum‐chemical calculations. All of the new compounds were characterized by IR, 1H, 11B, 13C NMR spectroscopy, and X‐ray crystallographic analysis.

AbstractThe shape‐controlled synthesis of metal nanoclusters (NCs) with precise atomic arrangement is crucial for tailoring the properties. In this work, we successfully control the shape of alloy NCs by altering the dopants in the alloying processes. The shape of the spherical [Pt1Ag24(SPhMe2)18] NC is maintained when [AuISR] is used as dopant. By contrast, the shape of Pt1Ag24 is changed to be rodlike by alloying with [AuI(PPh3)Br]. The structures of the trimetallic NCs were determined by X‐ray crystallography and further confirmed by both DFT and far‐IR measurements. The shape‐preserved [Pt1Au6.4Ag17.6(SPhMe2)18] NC is in a tristratified arrangement—[Pt(center)@Au/Ag(shell)@Ag(exterior)]—and is indeed the first X‐ray crystal structure of thiolated trimetallic NCs. On the other hand, the resulting rodlike NC ([Pt2Au10Ag13(PPh3)10Br7]) exhibits a high quantum yield (QY=14.7 %), which is in striking contrast to the weakly luminescent Pt1Ag24 (QY=0.1 %, about 150‐fold enhancement). In addition, the thermal stabilities of both trimetallic products are remarkably improved. This study presents a controllable strategy for synthesis of alloy NCs with different shapes (by alloying heteroatom complexes coordinated by different ligands), and may stimulate future work for a deeper understanding of the morphology (shape)–property correlation in NCs.

AbstractWith the widespread emergence of drug resistance, there is an urgent need to search for new antimicrobials, especially those against Gram‐negative bacteria. Along this line, the identification of viable targets is a critical first step. The protein translocase SecA is commonly believed to be an excellent target for the development of broad‐spectrum antimicrobials. In recent years, we developed three structural classes of SecA inhibitors that have proven to be very effective against Gram‐positive bacteria. However, we have not achieved the same level of success against Gram‐negative bacteria, despite the potent inhibition of SecA in enzyme assays by the same inhibitors. In this study, we use representative inhibitors as chemical probes to gain an understanding as to why these inhibitors were not effective against Gram‐negative bacteria. The results validate our initial postulation that the major difference in effectiveness against Gram‐positive and Gram‐negative bacteria is in the additional permeability barrier posed by the outer membrane of Gram‐negative bacteria. We also found that the expression of efflux pumps, which are responsible for multidrug resistance (MDR), have no effect on the effectiveness of these SecA inhibitors. Identification of an inhibitor‐resistant mutant and complementation tests of the plasmids containing secA in a secAts mutant showed that a single secA‐azi‐9 mutation increased the resistance, providing genetic evidence that SecA is indeed the target of these inhibitors in bacteria. Such results strongly suggest SecA as an excellent target for developing effective antimicrobials against Gram‐negative bacteria with the intrinsic ability to overcome MDR. A key future research direction should be the optimization of membrane permeability.

SummaryIntrusion detection systems (IDS) are systems aimed at analyzing and detecting security problems. The IDS may be structured into misuse and anomaly detection. The former are often signature/rule IDS that detect malicious software by inspecting the content of packets or files looking for a “signature” labeling malware. They are often very efficient, but their drawback stands in the weakness of the information to check (eg, the signature), which may be quickly dated, and in the computation time because each packet or file needs to be inspected. The IDS based on anomaly detection and, in particular, on statistical analysis have been originated to bypass the mentioned problems. Instead of inspecting packets, each traffic flow is observed so getting a statistical characterization, which represents the fingerprint of the flow. This paper introduces a statistical analysis based intrusion detection system, which, after extracting the statistical fingerprint, uses machine learning classifiers to decide whether a flow is affected by malware or not. A large set of tests is presented. The obtained results allow selecting the best classifiers and show the performance of a decision maker that exploits the decisions of a bank of classifiers acting in parallel.
Carolyn Rovee‐Collier's legacy to applied psychology, intervention, and public policy

Published: October 2016

AbstractIn this article, we reflect upon Carolyn Rovee‐Collier's pioneering research on learning and memory in infants, especially that using the mobile conjugate reinforcement task, for our understanding of (a) cognitive development in infants born prematurely and those with Down's syndrome and (b) her prediction that infants’ performance in the mobile conjugate reinforcement and similar operant tasks would predict later intellectual functioning. We then examine the implications of her research on time windows (the integration of new information into a memory) and memory reactivation (the retrieval of a forgotten memory as a result of the re‐exposure to a component of the original learning experience) for early intervention programs and clinicians treating victims of early trauma. We conclude with a discussion of the value of Rovee‐Collier's work for the growing field of infant/toddler science and how this science has informed public policy and program development.

AbstractUsing an eyelid conditioning paradigm modeled after that developed by Little, Lipsitt, and Rovee‐Collier (1984), Fifer et al. (2010) demonstrated that newborn infants learn during sleep. This study examined the role of sleep state in neonatal learning. We recorded electroencephalogram (EEG), respiratory, and cardiovascular activity from sleeping full term newborn infants during delay eyelid conditioning. In the experimental group (n = 21), a tone was paired with an air puff to the eye. Consistent with Fifer et al. (2010), newborn infants reliably learned during sleep. The experimental group more than doubled EMR rates to a tone alone, while a control group (n = 17) presented with unpaired tones and puffs maintained low EMR rates. Infant learners were more likely to produce a conditioned EMR during quiet sleep compared to active sleep. Understanding the influence of sleep state on conditioned responses will inform the potential use of eyelid conditioning for early screening.
Training effects and sex difference in preschoolers’ spatial reasoning ability
Authors: Joh Amy S. 
Published: October 2016

AbstractThis study examined sex difference in spatial reasoning, a type of spatial cognition necessary for everyday activities. An aggregated data set was composed of data from 273 3‐ to 4‐year olds who participated in 12 different studies using variants of the same spatial reasoning task. This data set was used to investigate whether and how sex difference is related to learning opportunities through training. The results showed that boys outperform girls in general, but this sex difference was influenced by training. When children received additional training, boys showed improved spatial reasoning ability compared to girls. But when children did not receive additional training, there was no sex difference. The type and amount of training did not influence the sex difference in this data set. These findings add to our understanding of how sex difference in spatial cognition emerges in early development.
Visual attention to meaningful stimuli by 1‐ to 3‐year olds: implications for the measurement of memory

Published: October 2016

AbstractThe visual recognition memory (VRM) paradigm has been widely used to measure memory during infancy and early childhood; it has also been used to study memory in human and nonhuman adults. Typically, participants are familiarized with stimuli that have no special significance to them. Under these conditions, greater attention to the novel stimulus during the test (i.e., novelty preference) is used as the primary index of memory. Here, we took a novel approach to the VRM paradigm and tested 1‐, 2‐, and 3‐year olds using photos of meaningful stimuli that were drawn from the participants’ own environment (e.g., photos of their mother, father, siblings, house). We also compared their performance to that of participants of the same age who were tested in an explicit pointing version of the VRM task. Two‐ and 3‐year olds exhibited a strong familiarity preference for some, but not all, of the meaningful stimuli; 1‐year olds did not. At no age did participants exhibit the kind of novelty preference that is commonly used to define memory in the VRM task. Furthermore, when compared to pointing, looking measures provided a rough approximation of recognition memory, but in some instances, the looking measure underestimated retention. The use of meaningful stimuli raise important questions about the way in which visual attention is interpreted in the VRM paradigm, and may provide new opportunities to measure memory during infancy and early childhood.

ABSTRACTObjectiveAdolescent emotional‐eating, referring to eating in response to negative affective states, is frequently reported by those with loss of control (LOC) eating. Although LOC eating has been shown to predict exacerbated disordered eating and excess weight/adiposity gain, the extent to which emotional‐eating, either alone or in combination with LOC, predicts adverse outcomes has not been determined. Thus, we examined associations of baseline emotional‐eating with changes in disordered eating, BMI, and adiposity over 1‐year, and to what degree the presence or absence of baseline LOC moderated these associations.Methods189 non‐treatment‐seeking youth (15.4 ± 1.4y; 66% female; 67% non‐Hispanic White, 38% overweight [BMI ≥ 85th %ile]) completed the emotional‐eating Scale for Children/Adolescents and the Eating Disorder Examination interview at baseline and again at 1‐year. Air displacement plethysmography assessed adiposity at both time points.ResultsBaseline emotional‐eating alone was not significantly associated with the development of objective binge eating or changes in disordered eating attitudes, BMI or adiposity 1‐year later. However, baseline emotional‐eating interacted with the presence of baseline LOC in the prediction of 1‐year outcomes. Among adolescents with LOC eating, greater baseline emotional‐eating was related to increased disordered eating attitudes (p = .03), BMI (p = .04), and adiposity (p = .04) at 1‐year, after correcting for false discovery rate.DiscussionEmotional‐eating among youth also reporting LOC was associated with adverse outcomes over 1‐year. Adolescents who report both behaviors may represent a subset of individuals at especially high risk for exacerbated disordered eating and excess weight gain. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2017; 50:551–560)
Dopaminergic activity and altered reward modulation in anorexia nervosa—insight from multimodal imaging
Authors: Bailer Ursula F. , Price Julie C. , Meltzer Carolyn C. , Wagner Angela , Mathis Chester A , Gamst Anthony , Kaye Walter H. 
Published: October 2016

ABSTRACTObjective: Individuals with anorexia nervosa (AN) have anxious and inhibited temperaments with high concern for consequences. Studies using either positron emission tomography (PET) or functional magnetic resonance imaging (fMRI) suggest involvement of the middle and dorsal caudate (DC) in individuals recovered (REC) from AN. For example, dopamine (DA) D2/D3 receptor binding in the middle caudate and DC was associated with anxiety and harm avoidance, and blood‐oxygen‐level‐dependent (BOLD) response in the DC was positively related to trait anxiety. It has not been shown yet whether BOLD response in individuals REC from AN was related to DA function.Methods: Post‐hoc correlation analyses between the PET and fMRI studies by correlating D2/D3 binding in striatal regions and BOLD signal in the anteroventral striatum (AVS) and DC for wins and losses respectively in 12 individuals REC from AN.Results: Individuals REC from AN with the greatest BOLD response in the DC in a monetary choice task had higher middle caudate D2/D3 binding, and greater anxiety and/or harm avoidance.Discussion: Though preliminary, these findings suggest that increased dorsal striatal D2/D3 binding is associated with enhanced cognitive response to feedback, potentially related to anxious anticipation of consequences. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2017; 50:593–596)

ABSTRACTObjectiveThe primary aim of the study was to examine the relationship across time between Facebook use and body image concern in adolescent girls.MethodA sample of 438 girls in the first two years (Years 8 and 9) of high school (aged 13‐15 years) at Time 1 completed questionnaire measures of Facebook consumption and body image concerns, and again two years later (Time 2).ResultsFacebook involvement increased substantially over the two year time period. Body image concerns also increased. Number of Facebook friends was found to prospectively predict the observed increase in drive for thinness. On the other hand, internalization and body surveillance prospectively predicted the observed increase in number of Facebook friends.DiscussionIt was concluded that Facebook “friendships” represent a potent sociocultural force in the body image of adolescent girls. © 2016 Wiley Periodicals, Inc.

Published: October 2016

SUMMARYWireless communications in industrial environments are seriously affected by reliability and performance issues, due to the multipath nature of obstacles within such environments. In order to utilize wireless systems for machine‐to‐machine applications in industrial environments, it is necessary to investigate and model their channel characteristics for optimal design and reliability assessment. However, the wireless channel characterization in such environments has not been sufficiently addressed in the literature within the scope of our knowledge. In this paper, to shed light on the channel modeling for plant applications, we measure and analyze the indoor channel characteristics in a typical thermal power plant. Our results indicate that the channel characterization of the plant environment is specific when compared with the general environments such as houses and offices. The findings in this paper provide a useful guidance to the design of wireless system for the realization of reliable control systems in power plants.

SUMMARYScent stimulation is widely used in day lives such as in aromatherapy. However, the effect of scent stimulation on humans remains unclear. Therefore, it is necessary to develop a system to evaluate the cardiovascular response to scent stimulation for use in biofeedback applications. In this study, we developed a device for quantitative and short‐term stimulation. We evaluated the heartbeat response to scent stimulation with this device. The experiments revealed that the R–R interval (RRI) was reduced by grapefruit scent stimulation. In addition, the RRI was likely to be controlled by scent stimulation with grapefruit and lavender.

SUMMARYIn this paper, we have investigated the growth technique of graphite‐coated nanomagnet particles to apply a sustainable environment technology by millisecond YAG pulsed laser ablation (PLA) method in ethanol solution using Fe bulk target. To control crystallized forms and/or grain size of nanomagnet materials, laser diode (LD) beam was irradiated to the ablation plumes, which were generated by this PLA method. In addition, magnetic field was applied to the ablation plumes, in order to separate a nanomagnet particle and a nonmagnet one. Ablation plumes were observed by high‐speed camera images, and they were reexcited by LD laser beam irradiation. In the case of magnetic field assist, ablation plumes were attracted to the magnet. This suggested that growth nanoparticles had magnetic property. Typical carbon‐coated nanoparticles, which grown by nonassisted PLA, were observed by TEM images, and these grain sizes were dependent on the pulsed width of PLA source. On the other hand, LD‐assisted samples showed there were rod‐sharped nanomaterials, and crystallization of these materials was β‐Fe3O4, γ‐Fe2O3 surmised by electron diffraction.

SUMMARYIn the late years, personal information must be protected at the agency in the field of insurance. We develop an agency contract system that protects personal information of the contractor and information to confirm intention to contract by background texture watermarks. When the contractor carries an application form, it may be folded, rumpled, or waved little. In this case, contractor's information must be recognized from background watermarks printed on the application form. But it cannot be recognized surely folded, rumpled, or waved application form by the conventional method. In this paper, we propose a new recognition of watermark dot information from folded, rumpled, or waved application form. The new recognition is composed of crooked point sequence recognition expressing character borders by searching around calculated point, and dot recognition by shading folded, rumpled, or waved paper and emphasizing dot in luminosity from this paper. As a result, we got correct recognition ratio of more than 99% from folded, rumpled, or waved paper.

Published: October 2016

SUMMARYWhen people listen to other's speech for the first time, they always attribute personality traits to the speaker subconsciously. We consider that if robots can predict personality traits of users from their speech, the communication in human–machine interaction will improve significantly. This paper proposes an approach for the automatic estimation of the traits, in which the listeners attribute to unanimous speakers. And the discrimination experiments based on hidden Markov model and canonical discrimination analysis show that, it is possible to predict with high accuracy (more than 75%), whether a speaker is perceived to be in the higher or lower part of the “Extraversion”, “Openness”, and “conscientiousness” by using nonverbal information.
