Authors: Wu Guodong , Feng Ping , Wan Xiang , Zhu Liqiang , Shi Yi , Wan Qing
Published: March 2016

Recent progress in using biomaterials to fabricate functional electronics has got growing attention for the new generation of environmentally friendly and biocompatible electronic devices. As a kind of biological material with rich source, proteins are essential natural component of all organisms. At the same time, artificial synaptic devices are of great significance for neuromorphic systems because they can emulate the signal process and memory behaviors of biological synapses. In this report, natural chicken albumen with high proton conductivity was used as the coupling electrolyte film for organic/inorganic hybrid synaptic devices fabrication. Some important synaptic functions including paired-pulse facilitation, dynamic filtering, short-term to long-term memory transition and spatial summation and shunting inhibition were successfully mimicked. Our results are very interesting for biological friendly artificial neuron networks and neuromorphic systems.

Published: March 2016

Cancer cells form actin-rich degradative protrusions (invasive pseudopods and invadopodia), which allows their efficient dispersal during metastasis. Using biochemical and advanced imaging approaches, we demonstrate that the N-WASP-interactors WIP and WICH/WIRE play non-redundant roles in cancer cell invasion. WIP interacts with N-WASP and cortactin and is essential for invadopodium assembly, whereas WICH/WIRE regulates N-WASP activation to control invadopodium maturation and degradative activity. Our data also show that Nck interaction with WIP and WICH/WIRE modulates invadopodium maturation; changes in WIP and WICH/WIRE levels induce differential distribution of Nck. We show that WIP can replace WICH/WIRE functions and that elevated WIP levels correlate with high invasiveness. These findings identify a role for WICH/WIRE in invasiveness and highlight WIP as a hub for signaling molecule recruitment during invadopodium generation and cancer progression, as well as a potential diagnostic biomarker and an optimal target for therapeutic approaches.

Published: March 2016

The diagnosis of early and aggressive types of cancer is important for providing effective cancer therapy. Cancer-induced fibrin clots exist only within lesions. Previously, we developed a monoclonal antibody (clone 102-10) that recognizes insoluble fibrin but not fibrinogen or soluble fibrin and confirmed that fibrin clots form continuously in various cancers. Here, we describe the development of a Fab fragment probe of clone 102-10 for tumour imaging. The distribution of 102-10 Fab was investigated in genetically engineered mice bearing pancreatic ductal adenocarcinoma (PDAC) and its effect on blood coagulation was examined. Immunohistochemical and ex vivo imaging revealed that 102-10 Fab was distributed selectively in fibrin clots in PDAC tumours 3 h after injection and that it disappeared from the body after 24 h. 102-10 Fab had no influence on blood coagulation or fibrinolysis. Tumour imaging using anti-fibrin Fab may provide a safe and effective method for the diagnosis of invasive cancers by detecting fibrin clots in tumour stroma.
Morphotype-specific effector functions of Cryptococcus neoformans PUM1
Authors: Kaur Jan Naseer , Panepinto John C.
Published: March 2016

The basidiomycete fungal pathogen Cryptococcus neoformans requires the PUF protein, Pum1, for hyphal morphogenesis during sexual development. In this study we found that Pum1 was auto-repressive under growth as yeast, but that auto-repression was relieved during filamentous growth through utilization of an alternative transcription start site driven by the master filamentation regulator Znf2. In addition, Pum1 was required to stabilize the ZNF2 mRNA through an indirect mechanism suggesting that Znf2 and Pum1 each positively regulate the expression of the other to achieve the filamentous morphotype required for sexual development in Cryptococcus.

Published: March 2016

Retinoid-related orphan receptor gamma t (RORγt) is a master transcription factor central to type 17 immunity involving cells such as T helper 17, group 3 innate lymphoid cells or IL-17-producing γδ T cells. Here we show that the intracellular ion channel TMEM176B and its homologue TMEM176A are strongly expressed in these RORγt+ cells. We demonstrate that TMEM176A and B exhibit a similar cation channel activity and mainly colocalise in close proximity to the trans-Golgi network. Strikingly, in the mouse, the loss of Tmem176b is systematically associated with a strong upregulation of Tmem176a. While Tmem176b single-deficiency has no effect on the course of experimental autoimmune encephalomyelitis, T cell or DSS-induced colitis, it significantly reduces imiquimod-induced psoriasis-like skin inflammation. These findings shed light on a potentially novel specific process linked to post-Golgi trafficking for modulating the function of RORγt+ cells and indicate that both homologues should be simultaneously targeted to clearly elucidate the role of this intracellular ion flow.
Microstructured Thin Film Nitinol for a Neurovascular Flow-Diverter
Authors: Chen Yanfei , Howe Connor , Lee Yongkuk , Cheon Seongsik , Yeo Woon-Hong , Chun Youngjae
Published: March 2016

A cerebral aneurysm occurs as a result of a weakened blood vessel, which allows blood to flow into a sac or a ballooned section. Recent advancement shows that a new device, ‘flow-diverter’, can divert blood flow away from the aneurysm sac. People found that a flow-diverter based on thin film nitinol (TFN), works very effectively, however there are no studies proving the mechanical safety in irregular, curved blood vessels. Here, we study the mechanical behaviors and structural safety of a novel microstructured TFN membrane through the computational and experimental studies, which establish the fundamental aspects of stretching and bending mechanics of the structure. The result shows a hyper-elastic behavior of the TFN with a negligible strain change up to 180° in bending and over 500% in radial stretching, which is ideal in the use in neurovascular curved arteries. The simulation determines the optimal joint locations between the TFN and stent frame. In vitro experimental test qualitatively demonstrates the mechanical flexibility of the flow-diverter with multi-modal bending. In vivo micro X-ray and histopathology study demonstrate that the TFN can be conformally deployed in the curved blood vessel of a swine model without any significant complications or abnormalities.
Age-Dependent Metastatic Spread and Survival: Cancer of Unknown Primary as a Model
Authors: Hemminki Kari , Pavlidis Nicholas , Tsilidis Konstantinos K. , Sundquist Kristina , Ji Jianguang
Published: March 2016

In order to describe a novel approach for the clinical study of metastases, we provide here age-specific incidence and survival data for cancer of unknown primary (CUP). Metastases in various organs are found at CUP diagnosis, which have implications for prognosis and we hypothesize similar prognostic implications for metastases found at diagnosis of primary cancers. We identified 33,224 CUP patients from the Swedish Cancer Registry and calculated incidence rates (IRs) for CUP development. Cox proportional hazards regression models were performed to estimate hazard ratios (HRs) for relative survival in CUP patients compared to the general population. In age-group specific analyses, a maximal IR was reached at age 85–89 years, followed by a marked decline to age 90+ (7-fold in men and 3-fold in women). The overall HR for relative survival declined systematically by age. CUP may be applied as an epidemiological age-incidence model for cancer metastases providing evidence in line with autopsy data that the metastatic potential, as shown by the incidence of CUP, appears to weaken markedly at age 85 years, depending on metastatic locations. The relative death rates were highest among young patients, which was probably entirely due to the low death rates in young background population.

Performance evaluation of interleaved high‐gain converter configurations
Authors: Choi Hyuntae , Jang Minsoo , Ciobotaru Mihai , Agelidis Vassilios G.
Published: March 2016

This study presents the experimental verification of an interleaved high‐gain (IHG) DC–DC converter using series and parallel configurations. The interleaved configurations allow the converter to achieve high voltage gain and high current rating, thus increasing the power rating of the converter. Analytical expressions for the design of these interleaved converter configurations are included in the study. The efficiency of the IHG DC–DC converter is increased due to the zero‐voltage switching of all active switches and the zero‐current switching of all diodes. Experimental results taken from three 1 kW prototypes with different configuration (non‐interleaved, and series and parallel interleaved) are presented to verify the interleaving performance and efficiency. Moreover, the effect of soft‐switching in terms of efficiency is demonstrated.
Photoelectric properties of three‐dimensional urchin‐like zinc oxide/titanium dioxide composite micronanostructures
Authors: Zhou Yi , Yang Luyue , Lu Jun , Wu Yiwei , Li Chaocheng , Liu Yuhuan , Li Mengyao
Published: March 2016

Three‐dimensional (3D) urchin‐like zinc oxide (ZnO)/titanium dioxide (TiO2) composite micronanostructures were first successfully synthesised using a facile electrochemical deposition method by depositing TiO2 into the surface of as‐prepared 3D urchin‐like ZnO, and polydienes dimethylammonium chloride as polycation solution. Photoelectric properties of the single 3D urchin‐like ZnO and the composite micronanostructures as dye‐sensitised solar cell (DSSC) anodes were investigated. During the deposition reaction, the TiO2 was exactly densely anchored onto the surface of 3D urchin‐like ZnO with uniform size, which were characterised by scanning electron microscopy, X‐ray diffraction, and energy dispersive X‐ray spectroscopy. The effects of different molar ratios of TiO2 and ZnO for the composite structure's morphology and photocatalytic activity were investigated systematically. The results indicated that the composite micronanostructures exhibited a larger adsorption range (−450 nm) and higher photoelectric conversion efficiency due to the synergistic effects, planar heterojunction, and mesoporous structure. When used as photoanodes for DSSCs, the I–V curve showed the photoelectric conversion efficiency of the novel composite was increased by 17.7% of that compared with the single 3D urchin‐like ZnO. These features collectively demonstrated the composite has a considerable potential for various applications in photocatalysis materials.
Der autologe Bypass zu den pedalen Seitenästen zur Vermeidung der Majoramputation
Authors: Dünschede F. , Paul N. , Meyer A. , Youssef M. , Espinola-Klein C. , Dopheide J. , Fottner C. , Vahl C. , Dorweiler B.
Published: March 2016

Hintergrund: Bei der kritischen Extremitätenischämie (CLI) liefert der pedale Bypass zur A. dorsalis pedis oder zur distalen A. tibialis posterior gute Langzeitergebnisse in Hinsicht auf Funktion und Fußerhalt. Im Einzelfall ist aber aufgrund des angiografischen Befunds ein Bypassanschluss auf pedale Seitenäste erforderlich.

Methode: In einer prospektiven Datenbank untersuchten wir alle Patienten, die bei schwerer Extremitätenischämie eine Bypassanlage zu einem pedalen Seitenast erhielten. Die Patienten wurden in regelmäßigen Abständen klinisch und mittels Duplexsonografie nachuntersucht. Wesentlicher Zielparameter war die Beinerhaltungsrate.

Ergebnisse: Von Januar 1998 bis Juni 2014 führten wir von insgesamt 534 pedalen Bypassanlagen 72 Bypässe zu pedalen Seitenästen bei 72 Patienten (59 Männer und 13 Frauen) durch. Die proximale Bypassanastomose lag in 30 Fällen supragenual und bei 42 Patienten infragenual. In 6 Fällen diente die A. tarsalis lateralis als Anschlussgefäß, in 15 Fällen die laterale und in 24 Fällen die mediale Plantararterie.

Research Update: The materials genome initiative: Data sharing and the impact of collaborative ab initio databases
Authors: Jain Anubhav , Persson Kristin A. , Ceder Gerbrand
Published: March 2016

Materials innovations enable new technological capabilities and drive major societal advancements but have historically required long and costly development cycles. The Materials Genome Initiative (MGI) aims to greatly reduce this time and cost. In this paper, we focus on data reuse in the MGI and, in particular, discuss the impact of three different computational databases based on density functional theory methods to the research community. We also discuss and provide recommendations on technical aspects of data reuse, outline remaining fundamental challenges, and present an outlook on the future of MGI’s vision of data sharing.

Published: March 2016

In order to improve the electrical behaviour of metal-insulator-metal capacitors with ZrO2 insulator grown by Atomic Layer Deposition, the influence of the insertion of interfacial Cr layers between Pt electrodes and the zirconia is investigated. An improvement of the α-voltage coefficient of capacitance as low as 567 ppm/V2 is achieved for a single layer of Cr while maintaining a high capacitance density of 10.7 fF/μm2 and a leakage current of less than 1.2 × 10−8 A/cm2 at +1 V. The role of the interface is discussed by means of X-ray photoelectron spectroscopy and high-resolution transmission electron microscopy showing the formation of Zr stabilized chromia oxide phase with a dielectric constant of 16.
First-principles study of migration and diffusion mechanisms of helium in α-Be
Authors: Yang Xiao-Yong , Lu Yong , Li Meng-Lei , Zhang Ping
Published: March 2016

The behavior of interstitial helium in α-Be has been studied with first-principles method. It is found that the most favored position for helium is the basal octahedral (BO) site, closely followed by the basal tetrahedral (BT) site, in agreement with previous predictions. The interaction energy between the helium and the neighborhood Be atoms and the deformation energy of α-Be matrix are calculated. The feasible minimum-energy pathways (MEP) of interstitial helium atoms in α-Be matrix and the corresponding atomic structures of the saddle points associated with the each MEP are investigated. The temperature-dependent diffusion coefficients have also been predicted. It is confirmed that the interstitial helium diffuses two-dimensionally at low temperatures; however, it can diffuse three-dimensionally at higher temperatures. Besides, the microscopic parameters in the pre-factor and activation energy of the diffusion coefficients are obtained. Both diffusion coefficients are higher than the available experiment data, which may attribute to the fact that under real condition the diffusion is not free, i.e. the actual α-Be matric has various defects and impurities which heavily affect the diffusion of helium. Therefore, our theoretical prediction is the upper bound for helium diffusion in α-Be matrix.
Nanoscale surface charge detection in epoxy resin materials using electrostatic force spectroscopy
Authors: El Khoury D. , Arinero R. , Laurentie J. C. , Castellon J.
Published: March 2016

Electrostatic force spectroscopy (EFS) operated in a conventional force gradient detection method allows determining local surface charges in epoxy samples. This is made possible through a detailed analysis of gradient versus DC voltage curves. The parabolic dependence of these curves is closely related to the charge density. Both maximum and origin-ordinate are key data from which it is possible to extract quantitative information on the detected charge. The study is based on the combined use of numerical and analytical simulations of the probe sample interaction. Excellent sensitivities to very low surface charge densities are reported.
V-shaped semisubmersible offshore wind turbine subjected to misaligned wave and wind
Authors: Karimirad Madjid , Michailides Constantine
Published: March 2016

The dynamic behavior of the V-shaped semisubmersible offshore wind turbine subjected to misaligned wave and wind loads in operational conditions is presented in this paper. During the life time of an offshore wind turbine, wave and wind can be misaligned which may affect the dynamic response and as a result the functionality of the floating wind turbine. Especially for asymmetric floating structures such as the V-shaped semisubmersible, the misalignment of the wave and wind may result in unexpected behavior. In the present study, integrated aero-hydro-servo-elastic analysis for coupled mooring-floater-turbine is carried out in order to investigate possible effects under misaligned wave and wind conditions. For misaligned wave and wind conditions, the wave-induced as well as the wave-wind-induced motions, tension of mooring lines, and functionality of the turbine such as power production, rotational speed, and controller actions like blade-pitch-angle are studied and presented. The results show that the V-shaped semisubmersible offshore wind turbine is not affected in an undesirable way by the misaligned wave and wind loads in operational conditions and can be considered as enough robust in such environmental conditions. Also, the functionality and power production of the current concept is not affected by the misalignment of the wave and wind. The wave-induced responses of the V-shaped floating wind turbine are relatively small compared to wave-wind-induced responses. The dynamic responses of the V-shaped semisubmersible offshore wind turbine in coupled wave-wind-induced analyses are mainly dominated by the wind loads effects.
In situ Detection of Amide A Bands of Proteins in Water by Raman Ratio Spectrum
Authors: Tang Cheng-qian , Lin Ke , Zhou Xiao-guo , Liu Shi-lin
Published: March 2016

The amide A band of protein is sensitive to the hydrogen bands of amide groups of proteins. However, it is hard to distinguish the amide A band of aqueous protein in situ directly, since it overlaps with O−H stretching vibration of water. In this work, we presented a new analytical method of Raman ratio spectrum, which can extract the amide A band of proteins in water. To obtain the Raman ratio spectrum, the Raman spectrum of aqueous protein was divided by that of pure water. A mathematical simulation was employed to examine whether Raman ratio spectrum is effective. Two kinds of protein, lysozyme and α-chymotrypsin were employed. The amide A bands of them in water were extracted from Raman ratio spectra. Additionally, the process of thermal denaturation of lysozyme was detected from Raman ratio spectrum. These results demonstrated the Raman ratio spectra could be employed to study the amide A modes of proteins in water.
Vibrational and Structural Dynamics of Mn(CO)5Br and Re(CO)5Br Examined Using Nonlinear Infrared Spectroscopy
Authors: Feng Min-jun , Yang Fan , Wang Jian-ping
Published: March 2016

Vibrational and structural dynamics of two transition metal carbonyl complexes, Mn(CO)5Br and Re(CO)5Br were examined in DMSO, using ultrafast infrared pump-probe spectroscopy, steady-state linear infrared spectroscopy and quantum chemistry computations. Two carbonyl stretching vibrational modes (a low-frequency A1 mode and two high-frequency degenerate E modes) were used as vibrational probes. Central metal effect on the CO bond order and force constant was responsible for a larger E-A1 frequency separation and a generally more red-shifted E and A1 peaks in the Re complex than in the Mn complex. A generally broader spectral width for the A1 mode than the E mode is believed to be partially due to vibrational lifetime effect. Vibrational mode-dependent diagonal anharmonicity was observed in transient infrared spectra, with a generally smaller anharmonicity found for the E mode in both the Mn and Re complexes.

Published: March 2016

The purpose of this note is to prove a stationary phase estimate well adapted to parameter dependent phases. In particular, no discussion is made on the positions (and behavior) of critical points, no lower or upper bound on the gradient of the phase is assumed, and the dependence of the constants with respect to derivatives of the phase and symbols is explicit.

The SH3 domain of UNC-89 (obscurin) interacts with paramyosin, a coiled-coil protein, inCaenorhabditis elegansmuscle

UNC-89 is a giant polypeptide located at the sarcomeric M-line of Caenorhabditis elegans muscle. The human homologue is obscurin. To understand how UNC-89 is localized and functions, we have been identifying its binding partners. Screening a yeast two-hybrid library revealed that UNC-89 interacts with paramyosin. Paramyosin is an invertebrate-specific coiled-coil dimer protein that is homologous to the rod portion of myosin heavy chains and resides in thick filament cores. Minimally, this interaction requires UNC-89’s SH3 domain and residues 294–376 of paramyosin and has a KDof ∼1.1 μM. In unc-89 loss-of-function mutants that lack the SH3 domain, paramyosin is found in accumulations. When the SH3 domain is overexpressed, paramyosin is mislocalized. SH3 domains usually interact with a proline-rich consensus sequence, but the region of paramyosin that interacts with UNC-89’s SH3 is α-helical and lacks prolines. Homology modeling of UNC-89’s SH3 suggests structural features that might be responsible for this interaction. The SH3-binding region of paramyosin contains a “skip residue,” which is likely to locally unwind the coiled-coil and perhaps contributes to the binding specificity.
Prologue
Authors: Gross Kali Nicole
Published: March 2016

The prologue introduces the case and explains why such a case matters for history. Specifically, it argues that Hannah Mary Tabbs, the woman at the center of the case, is important because she defies customary historical figures in African American history and black women’s studies in the sense that she is dishonest, violent, and, because of it, profoundly human. Her flaws allow us to see black women in history in a multidimensional way, which enhances history itself and also how we understand race, gender, and violence in the past and its impact on otherwise everyday women and men.
Wavy Hair and Nearly White Skin
Authors: Gross Kali Nicole
Published: March 2016

Chapter 4 examines the personal history and police treatment of George Wilson, the young man that Tabbs implicates during her police interrogation. This chapter explores how Wilson’s ability to pass for white negatively impacts how he is perceived by investigating authorities, the press, and the greater public. It also examines his confinement in the House of Refuge, a home for poor and wayward children, and the cycle of institutionalization that existed in his family. This chapters also maps the arraignment and the impending coroner’s inquest.
Changing Philosophical Concerns about Emergence and Media as Emerging: The Long View
Authors: Katz James E. , Robinson Elizabeth A.
Published: March 2016

Views of the history of either philosophy or technology can provoke opposite reactions. Some find that the more one examines the past, the more it seems that there is practically nothing profoundly novel in terms of the deeper human experience. For others, the world has always been changing, and may even be changing ever faster. The chapter proposes a middle path, arguing that though many of today’s pressing concerns are old, they emerge in new ways that require modifying our modes of intellectual approach. Moreover, the newest ideas and technologies may benefit from consideration under hoary rubrics. Its primary thesis is that a genuine continuity of life, technology, and human nature exists that prevents anything new from being a radical departure from the old. However, new innovations raise new problems and demand new solutions in ways that affect human reflection on even very old issues.
