The research in the Sentani was concucted in the Yomokho site to understand the strategy of human occupation and subsistence. Reconesaince survey and excavation was adopted in this research. Focus group discussion was also adopted in this research to test the most adoptable heritage socialication for the school students. Pottery is the main artifacts found in this research. The analysis also found that the past communities in the Yomokho site lived the traditional house. The main factor to consider this site as the place to live in the past was based on the location that nearby the lake and sago forest.Penelitian di Kawasan Danau Sentani dilakukan di Situs Yomokho untuk mengetahui strategi pemilihan tempat tinggal manusia pendukung budaya Situs Yomokho, dan pola subsistensi. Untuk itu dalam penelitian ini dilakukan survei permukaan tanah dan ekskavasi. Hasil ekskavasi di Situs Yomokho diperoleh temuan berupa fragmen gerabah polos maupun hias. Berdasarkan analisis data diketahui bahwa fragmen gerabah hanya ditemukan di lapisan tanah bagian atas yang berwarna hitam. Kondisi Bukit Yomokho berupa lereng bukit yang miring. Diasumsikan manusia pendukung Situs Yomokho tinggal di rumah panggung, tidak semua bagian bukit dipilih untuk mendirikan tempat tinggal, tetapi disesuaikan dengan kondisi lereng bukit dan kondisi tanah. Pemilihan Situs Yomokho sebagai hunian masa lalu didasarkan pada lokasinya yang dekat dengan danau dan didukung oleh keberadaan hutan sagu.
Influence of heat treatment on the structure, hardness and strength of ZnAl40Cu3 alloy
Authors: Michalik Rafał
Published: March 2017

This paper presents the results of studies on the effects of thermal treatment on the structure, hardness and strength of a high-aluminium monotectoid ZnAl40Cu3 alloy. The alloy was tested in the following conditions: after supersaturation at a temperature of 385 °C; after supersaturation at a temperature of 385 °C and subsequent ageing at temperatures of 125, 150 and 175 °C; and after annealing at a temperature of 185 °C. The studies revealed that annealing at a temperature of 185 °C causes a decrease in hardness and strength of ZnAl40Cu3 alloy. In contrast, the highest increase in hardness and strength was obtained by “incomplete” supersaturation at a temperature of 385 °C for 10 h. The increase in hardness and strength of the ZnAl40Cu3 alloy observed in the result of “incomplete” supersaturation at a temperature of 385 °C for 10 h may be connected with, most of all, formation of a quasi-dendritic structure. It was found that ageing of supersaturated samples causes a decrease in their hardness when compared to that of the samples after supersaturation.
Anatomy of Mammalian Replication Domains
Authors: Takebayashi Shin-ichiro , Ogata Masato , Okumura Katsuzumi
Published: March 2017

Genetic information is faithfully copied by DNA replication through many rounds of cell division. In mammals, DNA is replicated in Mb-sized chromosomal units called “replication domains.” While genome-wide maps in multiple cell types and disease states have uncovered both dynamic and static properties of replication domains, we are still in the process of understanding the mechanisms that give rise to these properties. A better understanding of the molecular basis of replication domain regulation will bring new insights into chromosome structure and function.
An Algorithm Based on GSVD for Image Encryption
Authors: Al-Kufi Mohammed , Hashim Hayder , Hussein Ameer , Mohammed Hind
Published: March 2017

This paper represents a new image encryption algorithm based on modifying generalized singular value decomposition (GSVD) by decomposing the plain-image into two segments using GSVD with an exchanged key-image to produce the cipher-image. The exchanged key-image is used as an encrypting and decrypting image. Mathematically, this procedure is represented by transforming the plain-image’s matrix into two different matrices and applying the GSVD with the exchanged key-image’s matrix to obtain the cipher-image’s matrix. The two encoded segments can be kept in several places or assigned to a group of authorized persons. No one can obtain the information of the image easily without the knowledge of the decrypting key. This proposed algorithm is represented as one of the digital image encryption techniques used to enhance the security of images that have been sent between recipients.
L'accident de Tchernobyl : une retombée positive en hydrogéologie
Authors: Sesiano Jean , Bueche Michel
Published: March 2017

Dans le cadre de recherches en hydrogéologie poursuivies depuis plusieurs années en Haute-Savoie (France), nous avons cherché à utiliser les retombées radioactives de l'accident de Tchernobyl comme traceur. Bien qu'ayant affaire à une très faible radioactivité et à une très grande dilution, on met en évidence une augmentation de la radioactivité aux deux sources qui ont été surveillées. L 'événement ayant coïncidé avec le début de la crue printanière, le temps de réponse du système est assez long, environ deux semaines, car il a fallu laisser à l'aquifère le temps de se recharger.
Observations préliminaires sur les cavités de la région du lac Centrum (NE Groenland)
Authors: Loubière Jean-François
Published: March 2017

En 1983, des cavités situées à l'extrême NE du Groenland ont été reconnues par M. Chiron, G. Favre, J.-F. Loubière et J.-P. Têtard. Au SW de la Terre du Kronprins Christian, terminaison nord de la grande chaîne plissée orientale du Groenland, s'étend une zone calcaire d'âge cambro-silurien. Dans ces formations, des réseaux karstiques ont été formés, à une époque où l'absence de permafrost et un climat plus clément permettaient une circulation des eaux souterraines. Ces conditions n'existent plus aujourd'hui. Durant les grandes glaciations quaternaires, ces grottes ont subi d'importantes modifications. En entaillant les plateaux, les glaciers ont mutilé les réseaux, d'où l'existence de tronçons ouverts sur le flanc des falaises. Les remplissages karstiques d'origine ont été remaniés par des apports allochtones constitués d'éléments éoliens et morainiques. Une première étude sur des planchers stalagmitiques (tests de datation par Résonance de Spin Electronique) indiquent qu'il s'agit de concrétionnements anciens remontant au moins au Pléistocène inférieur. De plus, l'observation au Microscope Electronique à Balayage a mis en évidence des champignons fossiles (Hyphochytridiomycètes) ne se développant plus à cette latitude. Le présent article nous interroge donc sur la transition paléo-climatique du Plio-Pléistocène dans une région proche du pôle.

Karst localities in Costa Rica and their geological background

Several karst localities in Costa Rica and some of their geological background have been already known by means of regional stratigraphic reconnaissances. However, a detailed exploration has not been accomplished yet, with only a few partial exceptions. Information on geological conditions, geomorphology, speleology, ecology and hydrogeology is only available from Barra Honda karst. General development of karst systems in Costa Rica has reached a young to moderately mature maximum stage with the occurence of classic features. Further studies are necessary to obtain a better idea of this kind of phenomena which shows a good potential as a water source and for tourism, ecology and industry. A brief description of the geology of Costa Rica with relation to the development of karst, is also offered in this text.
A la recherche des nouvelles espèces minérales découvertes en région lyonnaise de 1950 à 2008
Authors: Lelong Bernard
Published: March 2017

Jusqu'au milieu du XXe siècle, le nombre des espèces minérales connues était relativement limité : 400 environ, dans les différentes familles de roches. Fischesser en 1955 ne décrivait que 850 espèces environ. A partir de 1950, les descriptions de nouvelles espèces s'amplifient jusqu'à plus de 4000 espèces. Cette explosion tient à plusieurs raisons, et en premier lieu au développement de la microscopie classique, puis la microscopie électronique à balayage, la microsonde électronique permettant le dosage des éléments présents, enfin la diffraction des rayons X pour la détermination des structures. La région comporte beaucoup de gisements dont certains, anciens, ont fourni un grand nombre d'espèces minérales (Chessy par exemple, 109 validées).
Les Elateroidea (Coleoptera) de la Région Rhône-Alpes : les taupins ne manquent pas de ressort !

Elaterid coleoptera of Rhone-Alpes : the click-beetles do not miss a spring !

Elateroidea (Elateridae, Melasidae, Eucnemidae, Throscidae) are coleoptera little known by the public except the «Taupin» Agriotes lineatus, harmful to the farming. Carnivores in the larval state, the adults Elateroidea are saproxylic or, phytophagous and develop in all the habitats, except aquatic, and in numerous biotopes. 243 species are recorded in France among which 32 were added to the general catalog since 1972. 2/3 are known for the region Rhone-Alpes which harbours a very diverse fauna, in particular boreo-alpine, with glacial relics like Selatosomus and Berninelsonius. Some endemic taxa are pointed out : Athous dejeanii from Dauphiné and Anostirus pseudosulphuripennis in the Mont Pilat. Some southern taxa are advancing from Drome, but we know of no invasive ones. This group seems very stable in terms of regional variety except local disappearances of anthropic origin. It seems however urgent to lead a detailed exploration of the old woods and their forest canopies where doubtless remain rare species attached to trees with cavities and to recommend the preservation of these. the adults Elateroidea are saproxylic or, phytophagous and develop in all the habitats, except aquatic, and in numerous biotopes. 243 species are recorded in France among which 32 were added to the general catalog since 1972. 2/3 are known for the region Rhone-Alpes which harbours a very diverse fauna, in particular boreo-alpine, with glacial relics like Selatosomus and Berninelsonius.

La conscience morale et les questions posées par les documents récents du magistère romain
Authors: Thomasset Alain
Published: March 2017

Alors que Vatican II, en particulier dans Gaudium et Spes (1965), avait remis à honneur la place de la conscience dans le discernement moral, l’encyclique Veritatis Splendor (1993) en mettant en garde contre de possibles dérives a interprété la doctrine conciliaire dans un sens plus rigoureux. L’article examine les questions fondamentales posées par ce contraste, en particulier au sujet des actes dits « intrinsèquement mauvais », de la place des normes objectives et de la manière de définir l’objet de l’acte moral. Dans la dernière partie, il montre en quoi l’exhortation apostolique Amoris Laetitia (2016) du pape François infléchit à nouveau cette position magistérielle sur la conscience et la norme dans un sens plus sapientiel.
Application of WSN Fire Monitoring System in Coal Mining
Authors: Bai Chengyu
Published: March 2017

Targeted at the potential fire in coal mine production, this paper proposes a coal mine fire monitoring system based on Zig-bee technology, and discusses the network data transmission process in the system. When the system is applied to an actual coal mine, it achieves a sound fire monitoring effect. The wireless sensor network (WSN) coal mine fire monitoring system consists of such three subsystems as data acquisition subsystem, control center subsystem and emergency response subsystem. With sensor nodes as the basic unit, the WSN is divided into five parts: sensor module, treatment module, wireless communication module, location module and power supply module. The system can monitor the air temperature, humidity and smoke concentration of fire in the coal mine, and provide effective basis for monitoring department to make decisions on fire prevention and control measures. The on-site monitoring test shows that, in the event of a fire, the WSN can monitor the trend of fire in the coal mine effectively, reflect the temperature distribution in details, and issue alarms accurately. The conclusion offers a theoretical reference for the development of coal mine fire monitoring technology.
Autonomous Market Segments Estimation Using Density Conscious Artificial Immune System Learner
Authors: Pathak Vishwambhar
Published: March 2017

Automated exploration of groups of customers to understand customer behavior from raw data is highly required to support strategic decision making given the pressure of competitive market. Several mathematical and statistical methods have been applied for autonomous model estimation from multivariate data. The current paper investigates employability of new generation of bio-inspired metaheuristic algorithms, named the artificial immune system (AIS), which in the current proposition, learn through density based kernels. As such the model simulates probabilistic behavior of the dendritic cells (DCs) during recognition of the antigens and danger signals, whose learning has been modeled with an infinite Gaussian mixture model. The unsupervised learning capability of the model has been found to be effective for multivariate data.
Incorporating a New Technology for Patient Education
Authors: Wanner Eric T. , Bird Jennifer Lynne
Published: March 2017

This chapter explains the design of a survey that provides a new technology for physical therapy clinicians to use while treating patients. The new survey uses both numerical subjective and written subjective questions; the questions dovetail knowledge from the fields of writing and medicine to provide a resource for patient education. Encouraging a patient to write how he or she feels throughout the physical therapy process can increase the clinician's awareness, allowing for the modification of treatment when needed to achieve elite results for the patient. Reading a patient's writing also helps the clinician become more aware of whether the patient has a positive or negative outlook throughout the recovery process. The patient's development and maintenance of a positive outlook becomes a goal of the clinician. From this survey, the authors learned patients with a higher positive outlook throughout treatment sessions demonstrated greater healing gains in existing objective physical therapy measures.
Mastering Electronic Health Record in Global Health Care
Authors: Kasemsap Kijpokin
Published: March 2017

This chapter describes the overview of electronic health record (EHR); the trends and issues with EHR; EHR and clinical decision support system (CDSS); the trust and privacy concerns of EHR systems; and the significance of EHR in global health care. EHR systems are very important in health care settings and have the potential to transform the health care system from a mostly paper-based industry to the one that utilizes the clinical data and other pieces of information to assist health care providers in delivering the higher quality of care to their patients. EHRs and their ability to electronically exchange health information can help health care providers effectively provide higher quality and safer care for patients while creating tangible enhancements in global health care.

Published: March 2017

Nanostructured coatings offer great potential for various applications due to their superior characteristics that are not typically found in conventional coatings. This research aimed at developing a new and improved coating that employs zinc oxide nanopowder as the agent to achieve corrosion resistant properties for a coating. The research project discusses on its corrosion behaviour of epoxy-zinc oxide in different media by measuring its corrosion rate. Mild carbon steel was used as the substrate for the epoxy-zinc oxide coating. The corrosion behavior mechanism of mild steel was investigated in different media, namely fresh water, NaCl solution, HCl solution and NaOH solution. Immersion test was conducted and studied for a period of 60 days, with daily and weekly weighing and immersing. The corrosion rate was calculated and mild steel corrodes in the different environment and degrades in the following trend; HCl → NaCl → NaOH → H2O.
The use of and obstacles to social learning in climate change adaptation initiatives in South Africa
Authors: Mudombi Shakespear , Fabricius Christo , Van Zyl-Bulitta Verena , Patt Anthony
Published: March 2017

Global environmental change will have major impacts on ecosystems and human livelihoods while challenging the adaptive capacity of individuals and communities. Social learning, an ongoing adaptive process of knowledge generation, reflection and synthesis, may enhance people’s awareness about climate change and its impacts, with positive outcomes for their adaptive capacity. The objectives of this study were to assess the prevalence of factors promoting social learning in climate change adaptation initiatives in South Africa. An online survey was used to obtain the views of decision makers in government and non-governmental organisations about the presence of personal factors and organisational factors that promote social learning. Descriptive analysis was used to assess these issues. The findings provide some evidence of social learning in climate change adaptation projects in South Africa, with the majority of respondents indicating that personal social learning indicators were present. Mechanisms for improved conflict resolution were, however, less prevalent. The organisational and governance-related barriers to implementation also presented significant challenges. Some of the main organisational barriers were short timeframes for implementing projects, inadequate financial resources, political interference, shortcomings in governance systems and lack of knowledge and expertise in organisations. There is a need for organisations to promote social learning by ensuring that their organisational environment and governance structures are conducive for their employees to embrace social learning. This will help contribute to the overall success of climate change adaptation initiatives.
Radiologic-Pathologic Correlation: Acellular Dermal Matrix (Alloderm®) Used in Breast Reconstructive Surgery
Authors: Lee Christine U , Bobr Aleh , Torres-Mora Jorge
Published: March 2017

Acellular dermal matrix (ADM) such as Alloderm®is sometimes used in tissue reconstruction in primary and reconstructive breast surgeries. As ADM is incorporated into the native tissues, the evolving imaging findings that would correlate with varying degrees of host migration and neoangiogenesis into the matrix can be challenging to recognize. In the setting of a palpable or clinical area of concern after breast reconstructive surgery following breast cancer, confident diagnosis of a mass representing ADM rather than recurring or developing disease can be challenging. Such diagnostic imaging uncertainties generally result in short-term imaging and clinical follow-up, but occasionally, biopsy is performed for histopathological confirmation of benignity. A case of biopsy-proven Alloderm®is described. To the best of our knowledge, this is the first radiologic-pathologic correlation of ADM in the literature.
Edward Hopper y su casa-estudio en Cape Cod. Dibujos y pinturas entre recuerdos y experiencias
Authors: Molinero Sánchez Jorge
Published: March 2017

En 1934 Edward Hopper diseñó y construyó su casa de verano junto al mar en Cape Cod a partir de las experiencias vividas en las casas que habitó y en las arquitecturas de sus cuadros (Figs. 1 a 4). Tomando como base el modelo de casa Cape Cod Cottage, adaptó esta tipología para su nueva residencia tras el conocimiento que de esta construcción había adquirido al pintarla frecuentemente en sus cuadros durante los veranos. El agua de su casa natal de Nyack, la luminosidad del estudio en Nueva York y la posición elevada de los faros de sus lienzos, serán elementos con los que construirá este íntimo espacio para vivir, pensar y pintar. La forma en que Hopper ideó y materializó sus cuadros era similar al proceso de elaboración del proyecto arquitectónico y nos revela un arquitecto que utilizó su experiencia artística para el diseño y construcción de su casa-estudio.
A Tale of Two Social Philosophies
Authors: Frega Roberto
Published: March 2017

Although less known than his theory of democracy, John Dewey's social philosophy provides an articulate and original perspective on political life based on pragmatist intuitions. Dewey's struggle with social philosophy spanned more than four decades of his intellectual life. This article provides an overview of the main themes that characterize it and shows that two distinct projects animate Dewey's social philosophy. One is closer to the British reformist social philosophy of Jeremy Bentham and John S. Mill. Another is closer to the program of a critical theory of society initially developed by Karl Marx and subsequently expanded by the Frankfurt school. The article contends that to understand Dewey's social philosophy we should first understand what he took and what he rejected from both these tradition, how he managed to steer a middle course between Mill and Marx.

Determinants for non-take-up of informal help: a literature review

A major issue confronting Dutch municipalities is that informal help is not being accepted. This concerns potential clients who avoid or are reluctant to ask for support that can be provided by friends, family, neighbours or volunteers. This phenomenon of non-acceptance is still underexplored and our theoretical understanding is fragmented at best. We explore various explanations for why people avoid seeking help, drawn from various and – until now – largely separate bodies of literature. From an extensive literature review across the disciplines of psychology, sociology and public administration, we distil four possible causes for refusing to accept help. We conclude with a discussion of the practical implications and possible future research avenues.

About 60% of emerging infectious diseases in humans are of zoonotic origin. Their increasing number requires the development of new methods for early detection and monitoring of infectious agents in wildlife. Here, we investigated whether blood meals from hematophagous flies could be used to identify the infectious agents circulating in wild vertebrates. To this aim, 1230 blood-engorged flies were caught in the forests of Gabon. Identified blood meals (30%) were from 20 vertebrate species including mammals, birds and reptiles. Among them, 9% were infected by different extant malaria parasites among which some belonged to known parasite species, others to new parasite species or to parasite lineages for which only the vector was known. This study demonstrates that using hematophagous flies as ‘flying syringes’ constitutes an interesting approach to investigate blood-borne pathogen diversity in wild vertebrates and could be used as an early detection tool of zoonotic pathogens.
The Sensed Presence Questionnaire (SenPQ): initial psychometric validation of a measure of the “Sensed Presence” experience
Authors: Barnby Joseph M. , Bell Vaughan
Published: March 2017

Background

The experience of ‘sensed presence’—a feeling or sense that another entity, individual or being is present despite no clear sensory or perceptual evidence—is known to occur in the general population, appears more frequently in religious or spiritual contexts, and seems to be prominent in certain psychiatric or neurological conditions and may reflect specific functions of social cognition or body-image representation systems in the brain. Previous research has relied on ad-hoc measures of the experience and no specific psychometric scale to measure the experience exists to date.

Methods

Based on phenomenological description in the literature, we created the 16-item Sensed Presence Questionnaire (SenPQ). We recruited participants from (i) a general population sample, and; (ii) a sample including specific selection for religious affiliation, to complete the SenPQ and additional measures of well-being, schizotypy, social anxiety, social imagery, and spiritual experience. We completed an analysis to test internal reliability, the ability of the SenPQ to distinguish between religious and non-religious participants, and whether the SenPQ was specifically related to positive schizotypical experiences and social imagery. A factor analysis was also conducted to examine underlying latent variables.

Results

The SenPQ was found to be reliable and valid, with religious participants significantly endorsing more items than non-religious participants, and the scale showing a selective relationship with construct relevant measures. Principal components analysis indicates two potential underlying factors interpreted as reflecting ‘benign’ and ‘malign’ sensed presence experiences.

Discussion

The SenPQ appears to be a reliable and valid measure of sensed presence experience although further validation in neurological and psychiatric conditions is warranted.

El objetivo del estudio fue analizar las percepciones de hombres y mujeres respecto de cambios en las relaciones de género ocurridos en contextos de transformaciones políticas, económicas e institucionales en Chile entre 1973 y 2010 y las condiciones facilitadoras de sus entornos familiares, sociales, laborales, culturales e institucionales para cuestionar las desigualdades de género. El estudio adoptó una metodología cualitativa de tipo descriptiva y con un enfoque biográfico. La muestra intencionada estuvo constituida por 25 hombres y mujeres profesionales, pertenecientes a 2 generaciones de acuerdo a su momento de ingreso al mercado laboral (1973-1989 y 1990-2010), con quienes se realizaron relatos de vida. Los/as narradores/ras de ambas generaciones reconocieron cambios importantes en las relaciones de género en distintos ámbitos sociales, destacando las positivas consecuencias de ello, especialmente para las mujeres. Señalaron, además, condiciones a nivel familiar, laboral, educacional y social que favorecieron las transformaciones de las relaciones de género. Se pudieron identificar en los relatos de hombres y mujeres mecanismos de interacción social que reproducen desigualdades, lo que evidencia la complejidad de las transformaciones del orden de género.
Norbert Elias and Figurational Sociology
Authors: van Krieken Robert
Published: March 2017

Norbert Elias (1897–1990) was an influential German sociologist. His impact on sociological thought includes a concern with long‐term historical processes, including the history of violence, which can be understood as either civilizing or decivilizing, the development of a processual and relational approach to social thought that transcends oppositions, such as individual–society or structure–agency, and the central placement of the concept of “habitus,” or psychological and emotional disposition, in sociological explanations of social stability and change. He has been described as the last great classical sociologist, linking together the conceptual approaches of Durkheim, Marx, Weber, Simmel, and Freud.
Understanding the Impact of Green Initiatives and Green Performance on Financial Performance in the US
Authors: Li Suhong , Ngniatedema Thomas , Chen Fang
Published: March 2017

Sustainable development has received increasing attention in recent literature, driven by increased environmental concerns. We study the influence of green initiatives and green performance on financial performance for the top 500 publicly traded companies in the USA by industry sector. Green initiatives are measured using the concepts Green Pay Link, Sustainability Themed Committee and Audit. Green performance is measured using Energy Productivity, Carbon Productivity, Water Productivity, Waste Productivity and Green Reputation. The results show that green initiatives have a negative impact on Energy Productivity and Green Reputation, and that both green initiatives and green performance have a significant impact on financial performance. These results are mixed and vary by industry sector. The results suggest that companies take a reactive, not proactive, approach in the implementation of green initiatives. In addition, the results suggest that the impact of green performance on financial performance is not immediate, and may take more than a year for companies to observe.

Effect of Copper‐based Catalyst Support on Reverse Water‐Gas Shift Reaction (RWGS) Activity for CO2 Reduction
Authors: Jurković Damjan Lašič , Pohar Andrej , Dasireddy Venkata D. B. C. , Likozar Blaž
Published: March 2017

Cu‐based bifunctional materials were examined for carbon dioxide conversion, thus producing the syngas from hydrogen, which can be attained using surplus electrical energy. Catalysts were synthesized by deposition‐precipitation fabrication method, i.e., copper on Al2O3, CeO2, SiO2, TiO2, and ZrO2. To investigate chemical reaction kinetics, the turnover was screened in a parallel high‐throughput packed‐bed reactor system. The results indicated that catalytic pathway mechanisms were affected by the substrate. An optimal supporting oxide may thus contribute to the engineering and intensification of unconventional feedstock processing, e.g., CO2, as well as the design of emerging catalysis routes. The produced synthesis gas may be readily used for basic chemical platforms, such as methanol.
A Vinyl‐Cation‐Induced 1,3‐Aryl Shift
Authors: Fu Liang , Damsen Helena , Niggemann Meike
Published: March 2017

A net insertion of an unactivated, internal alkyne into a sp2–sp3 C−C bond of simple benzylic alcohols was achieved using the rearrangement of a highly reactive vinyl cation intermediate to a stabilized allyl cation as the driving force for an unusual 1,3‐carbon shift reaction. In the presence of 10 mol % of Al(OTf)3 as a simple, inexpensive, and abundant catalyst, high selectivity for the rearrangement was achieved. The reaction scope proved general with regard to both the alkyne and the benzylic alcohol and a range of 1,2‐dihydroquinolines as well as 2H‐chromenes were obtained.

Human p300 is a polyhedric transcriptional coactivator that plays a crucial role in acetylating histones on specific lysine residues. A great deal of evidence shows that p300 is involved in several diseases, including leukemia, tumors, and viral infection. Its involvement in pleiotropic biological roles and connections to diseases provide the rationale to determine how its modulation could represent an amenable drug target. Several p300 inhibitors (i.e., histone acetyltransferase inhibitors, HATis) have been described so far, but they all suffer from low potency, lack of specificity, or low cell permeability, which thus highlights the need to find more effective inhibitors. Our cinnamoyl derivative, 2,6‐bis(3‐bromo‐4‐hydroxybenzylidene)cyclohexanone (RC56), was identified as an active and selective p300 inhibitor and was proven to be a good hit candidate to investigate the structure–activity relationship toward p300. Herein, we describe the design, synthesis, and biological evaluation of new HATis structurally related to our hit; moreover, we investigate the interactions between p300 and the best‐emerged hits by means of induced‐fit docking and molecular‐dynamics simulations, which provided insight into the peculiar chemical features that influence their activity toward the targeted enzyme.
FeS–ZnS Composite Nanosheets for Enhanced Lithium Storage Properties
Authors: Xu Chen , Tan Hui Teng , Ulaganathan Mani , Yan Qingyu
Published: March 2017

Ultrathin hybrid nanosheets composed of FeS and ZnS nanocrystals have been synthesized by an organic solution‐based synthesis. The formation mechanism of the composite nanosheets is associated with the dodecane thiolate‐templated growth of FeS nanocrystals before undergoing self‐assembly into 2D secondary structures. The pre‐existing FeS nanocrystals are used as heterogeneous seeds to facilitate the nucleation and growth of ZnS in the vicinity. From the preliminary results, the composite sulfide with a molar ratio of Fe/Zn=7.29 exhibits specific capacities of 805, 705, 567, 381, and 245 mA h g−1 at current densities of 0.1, 0.5, 1, 2, and 5 A g−1, respectively, which are higher than electrodes with other ratios and the single component counterparts. Trace amounts of ZnS nanocrystals that are embedded in the FeS matrix bolstered the high capacity resulting from the contribution from ZnS. Meanwhile, this FeS/ZnS nanosheet composite can also sustain a high capacity upon cycling, ascribed to the mutual segregation of the heterogeneous sulfides, in which the co‐existence of the heterogeneous sulfides could behave as mutual dispersants to prevent them from aggregating in either lithiation and delithiation processes.

The increasing volume of uncertain data has resulted in a dire need for supporting efficient uncertain data management. The skyline query as an important aspect of data management has received considerable attention in recent years, because of its importance in making intelligent decisions over complex data. Moreover, data collection and storage have become increasingly distributed, which makes the central assembly of data for storage and query infeasible and inefficient. Although many research efforts have been conducted to address the skyline query problem in various distributed scenarios, we still lack algorithms to address the queries over interval data, which is a special kind of attribute‐level uncertain data that widely exists in many applications. In this paper, we extensively study the skyline query over distributed interval data. We model the skyline query problem and define the distributed skyline query over interval data. Particularly, 2 efficient algorithms are proposed to retrieve the skylines progressively from distributed local sites with a highly optimized feedback framework. Moreover, we exploit 2 strategies for further improving the queries. Extensive experiments on synthetic and real datasets with real deployment are conducted to validate the effectiveness and efficiency of our proposals.

Multipath transmission control protocol(TCP), or MPTCP, is a widely‐researched mechanism that allows a single application‐level connection to be split to more than 1 TCP stream and, consequently, more than 1 network interface, as opposed to the traditional TCP/IP model. Being a transport layer protocol, MPTCP can easily interact between the application using it and the network supporting it. However, MPTCP does not have control of its own route. Default IP routing behavior generally takes all traffic through the shortest or best metric path. However, this behavior may actually cause paths to collide with each other, creating contention for bandwidth in a number of edges. This can result in a bottleneck that limits the throughput of the network. Therefore, a multipath routing mechanism is necessary to ensure smooth operation of MPTCP. We created smoc, a simple multipath OpenFlow controller, that uses only topology information of the network to avoid collision where possible. Evaluation of smoc in a virtual local‐area and a physical wide–area software‐defined networks showed favorable results as smoc provided better performance than simple or spanning tree–routing mechanisms.

Nitrogen is one of the most important nutrients for plant growth and a major constituent of proteins that regulate photosynthetic and respiratory processes. However, a comprehensive global analysis of nitrogen allocation in leaves for major processes with respect to different plant functional types (PFTs) is currently lacking. This study integrated observations from global databases with photosynthesis and respiration models to determine plant‐functional‐type‐specific allocation patterns of leaf nitrogen for photosynthesis (Rubisco, electron transport, light absorption) and respiration (growth and maintenance), and by difference from observed total leaf nitrogen, an unexplained “residual” nitrogen pool. Based on our analysis, crops partition the largest fraction of nitrogen to photosynthesis (57%) and respiration (5%) followed by herbaceous plants (44% and 4%). Tropical broadleaf evergreen trees partition the least to photosynthesis (25%) and respiration (2%) followed by needle‐leaved evergreen trees (28% and 3%). In trees (especially needle‐leaved evergreen and tropical broadleaf evergreen trees) a large fraction (70% and 73%, respectively) of nitrogen was not explained by photosynthetic or respiratory functions. Compared to crops and herbaceous plants, this large residual pool is hypothesized to emerge from larger investments in cell wall proteins, lipids, amino acids, nucleic acid, CO2 fixation proteins (other than Rubisco), secondary compounds, and other proteins. Our estimates are different from previous studies due to differences in methodology and assumptions used in deriving nitrogen allocation estimates. Unlike previous studies, we integrate and infer nitrogen allocation estimates across multiple PFTs, and report substantial differences in nitrogen allocation across different PFTs. The resulting pattern of nitrogen allocation provides insights on mechanisms that operate at a cellular scale within leaves, and can be integrated with ecosystem models to derive emergent properties of ecosystem productivity at local, regional, and global scales.

In this investigation, a natural‐gas (NG) treatment system for NG sources with high CO2 content is simulated experimentally and theoretically using Aspen Plus. The concept uses patented heat exchangers and a process design developed as part of the cryogenic carbon capture(CCC) process to remove enough CO2 to enable the treated gas to be handled without the modification of traditional NG equipment. Simultaneously, the process removes liquefied natural gas (LNG) very efficiently. This process provides a simpler alternative to the solvent‐based CO2 removal, absorbent drying, and cryogenic NG liquid extraction systems found in traditional NG processing. The data from an experimental bench‐scale apparatus verify the results of the simulations as a function of NG composition and pressure. Costing parameters, exergy loss, and heat‐exchanger efficiency are also discussed. The results confirm low exergy losses for bench‐scale apparatus. The system uses heat exchangers with efficiencies of more than 90 %. High pressure and low methane content in the NG result in high CO2 capture.
Postregistration monitoring of pesticides is urgently required to protect ecosystems

Current admission policies for pesticides follow a controlled experimental tiered risk assessment approach, giving results that are difficult to extrapolate to a real-world situation. Later analyses of compounds such as DDT and neonicotinoid pesticides clearly show that the actual chemical impacts frequently affect many more components of an ecosystem than a priori suggested by risk assessment. Therefore, to manage the actual risks for ecosystems imposed by manufactured compounds, it is proposed that current admission policies for chemicals be enriched by using postregistration monitoring. Such monitoring is essential to identify unexpected direct and indirect impacts on organisms by accounting for multiple propagation routes and exposures. Implementation of postregistration monitoring could build on existing monitoring networks. This approach would tackle the current policy impasse of compartment-based regulations versus exposure-based regulations, and, more importantly, would provide a safety lock for risk assessment across compartments and more likely ensure the protection of our natural environment.

Published: March 2017

Titanium dioxide nanoparticles (TiO2 NPs) are increasingly used in daily life, in industry, and in environmental clearing, but their potential neurodevelopmental toxicity has been highly debated. In this study, we explored whether TiO2 NPs inhibited development of dendritic morphology and identified possible molecular mechanisms associated with this inhibition in primary cultured rat hippocampal neurons. Results showed that TiO2 NPs decreased neurite length, the number of branches and the spine density, and impaired mitochondrial function in the developing neurons. Furthermore, TiO2 NPs significantly reduced the expression of several proteins involved in canonical Wnt3a/β‐catenin signaling including Wnt3a, β‐catenin, p‐GSK‐3β, and CyclinD1 and conversely, elevated GSK‐3β expression. In addition to altering expression of proteins involved in canonical Wnt3a/β‐catenin signaling, TiO2 NPs decreased expression of proteins invovled in non‐canonical Wnt signaling, including, MKLP1, CRMP3, ErbB4, and KIF17. Taken together, these results indicate that suppression of dendritic development caused by TiO2 NPs is associated with inhibition of activation of the Wnt/β‐catenin pathway or non‐canonical Wnt pathway‐induced expression of microtubule cytoskeletal components in the developing neurons. © 2017 Wiley Periodicals, Inc.

We report on a germanium Fabry‐Perot interferometer heated with a Nd:YAG laser. The transmission property of the laser‐heated germanium Fabry‐Perot interferometer has been investigated experimentally and theoretically. The transmission of CO2 laser through the germanium Fabry‐Perot interferometer varied with Nd:YAG laser heating. The theoretical results are in good agreement with the experimental results. The technique of laser‐heated germanium Fabry‐Perot interferometry is promising for applications in laser modulation and detection. © 2017 Wiley Periodicals, Inc.

Authors: Meng Guan Tan , Rahim S.K.A.
Published: March 2017

In this project, a compact monopoles Multiple‐Input‐Multiple‐Output MIMO antenna with size 40 × 42 mm2 that operates at 7 GHz is designed and proposed for 5th Generation mobile networks (5G) application. The antenna is built by using FR‐4 substrate and it consists of two planar antenna elements which arranged orthogonally to provide a good isolation between them. To further enhance the isolation and decrease the mutual coupling effect, a rod‐like parasite element is added in the design. Initial simulation result shows that the antenna can operate from 4 GHz to 9 GHz while measurement result proves that it can operate from 5.5 GHz to 9 GHz. Both results show that isolation is below −20 dB. © 2017 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:1074–1077, 2017

Published: March 2017

This article presents a study of antenna alignment impact on bit error rate for a wireless link between two directive W‐band horn antennas where one of them is mechanically steered by a Stewart platform. Such a technique is applied to find the optimal alignment between transmitter and receiver with an accuracy of 1° both in azimuth and elevation angles. The maximum degree of misalignment which can be tolerated is also reported for different values of optical power in the generation of W‐band signals by photonic up‐conversion. © 2017 Wiley Periodicals, Inc.
