description: H. Akbar-Zadeh has recently proposed (J Geom Phys 17 (1995) 342) a new geometric formulation of Einstein-Maxwell system with source in terms of what are called "Generalized Einstein manifolds". We show that, contrary to the claim, Maxwell equations have not been derived in this formulation and that, the assumed equations can be identified only as source-free Maxwell equations in the proposed geometric set up. A genuine derivation of source-free Maxwell equations is presented within the same framework. We draw a conclusion that the proposed unification scheme can pertain only to source-free situations.

This gives new types of integrable coupled derivative nonlinear Schrödinger equations. By virtue of a gauge transformation, a new multi-component extension of a derivative nonlinear Schrödinger equation proposed by Kaup-Newell is also obtained.

description: The conversion between microwave photons and optical photons with quantum coherence is important for quantum communication and computation. In this paper, we report a proposal using an ensemble of atoms coupled to microwave and optical resonators. Input photons to one resonator are converted into output photons in the other resonator without active operation. Usually the conversion is only optimized at certain frequency. In our proposal, we find that the efficiency is almost a constant and can be close to 100% in a large interval of frequency, i.e. a high-bandwidth conversion can be realized with our proposal.

description: The cullin-RING E3 ubiquitin ligases (CRLs) play crucial roles in modulating the stability of proteins in the cell and are, in turn, regulated by post-translational modification by the ubiquitin-like (Ubl) protein NEDD8. This process, termed neddylation, is reversible through the action of the COP9 signalosome (CSN); a multi-subunit metalloprotease conserved among eukaryotes that plays direct or indirect roles in DNA repair, cell signaling and cell cycle regulation in part through modulating the activity of the CRLs. Previously, inhibition of CRL neddylation by MLN4924, a small molecule inhibitor of the NEDD8-activating enzyme 1 (NAE1), was shown to induce interphase cell cycle arrest and cell death. Using fixed and living cell microscopy, we re-evaluated the cell cycle effects of inhibition of neddylation by MLN4924 in both asynchronous and mitotic cell populations. Consistent with previous studies, treatment of asynchronous cells with MLN4924 increased CDT1 expression levels, induced G2 arrest and increased nuclear size. However, in synchronized cells treated in mitosis, mitotic defects were observed including lagging chromosomes and binucleated daughter cells. Consistent with neddylation and deneddylation playing a role in cytokinesis, NEDD8, as well as subunits of the CSN, could be localized at the midbody and cleavage furrow. Finally, treatment of mitotic cells with MLN4924 induced the premature accumulation of MKLP1 at the cleavage furrow, a key regulator of cytokinesis, which was concomitant with increased abscission delay and failure. Thus, these studies uncover an uncharacterized mitotic effect of MLN4924 on MKLP1 accumulation at the midbody and support a role for neddylation during cytokinesis.

description: We report on the behavior of Ge-Ge, Ge-Sn, Sn-Sn like and disorder-activated vibrational modes in GeSn semiconductors investigated using Raman scattering spectroscopy. By using an excitation wavelength close to E1 gap, all modes are clearly resolved and their evolution as a function of strain and Sn content is established. In order to decouple the individual contribution of content and strain, the analysis was conducted on series of pseudomorphic and relaxed epitaxial layers with a Sn content in the 5-17at.% range. All vibrational modes were found to display the same qualitative behavior as a function of content and strain, viz. a linear downshift as the Sn content increases or the compressive strain relaxes. Simultaneously, Ge-Sn and Ge-Ge peaks broaden, and the latter becomes increasingly asymmetric. This asymmetry, coupled with the peak position, is exploited in an empirical method to accurately quantify the Sn composition and lattice strain from Raman spectra.

description: With over half a century of medical ultrasound support, proven efficacy, and increased popularity, why is it that over half our planet’s population does not have access to ultrasound imaging? In 2015 when I joined the doctoral program, I embarked to not only understand this problem but to provide a solution. This document will walk you through this journey, detailing the challenge of creating my very own ultrasound system with the purpose of it being highly accessible to people who need it the most. I had the vision to take this further; not only did I aim to create an open-source portable ultrasound- I also wanted to see this in the hands of users. This dissertation will show you how collaboration between students of varying disciplines can help propel research to the point of product development. A full ultrasound system including both hardware and software has been developed and tested using commercial ultrasound phantoms. This document will present progress chronologically, starting with the first attempts at using audible piezoelectric buzzers to generate a signal, where the first proof of concept is met. In this dissertation, you will follow the continuous development of a 1) ultrasound analog circuit, 2) mechanical transducer probe, 3) analog signal acquisition system, and 4) imaging software coupled with the user interface. The open-source portable ultrasound research has been successful in providing both hardware and software solutions, combined as a single package in an end-to-end integrated system. This has never been done before. During a time when “data is gold”, this project has also created an open platform where users can collect and share data, enabling collaborations and propulsion of open-access medical screening technologies. This research has developed the lowest-cost 3D scanning ultrasound transducer that we know of at this time. This is inherently novel and transcendental.

Ultrasound Data Communications for Ultra-low-power Wake-up in Sensor Nodes
Creators: Yadav, Kshitij
Publisher: name: Columbia University
Year: 2012
Subjects: Electrical engineering

description: In the power-starved wireless sensor node application, the main transceiver has to be duty-cycled to prolong the node battery lifetime. Wake-up is among the lowest power schemes to accomplish this; an always ON low-power receiver called the wake-up receiver is used to turn ON the main receiver when needed. In this thesis, we have demonstrated ultra-low-power wake-up by using through-air wireless ultrasound. We have achieved more than an order of magnitude reduction in wake-up receiver power consumption, compared to conventionally used radio frequencies. An ultra-low-power ultrasonic wake-up receiver IC was designed in a 65-nm CMOS process and has a power consumption of only 4.4 uW. For the proof-of-concept prototype demonstrated in this work, the digital back-end circuits were been implemented on a commercial FPGA. An ultrasound data network consisting of three receivers and one transmitter was set up in a lecture hall. For a transmit power of 27 uW, less than 10 % of the wake-up packets, at 1 pkt/s, were missed at each of the three receivers. All the system blocks: receiver IC, ultrasound communication channel and TX-RX transducer pair, were individually characterized in different environments to understand the interaction between the electrical and mechanical domains. Also presented are techniques for increasing the distance ranges of wireless ultrasound and communication schemes for extending the use of ultrasound to environments where line-of-sight communication is not possible.

description: • Microtendipes rydalensis (Edwards, 1929)
is a Chironomidae species which is widely distributed species in Europe with a characteristic mentum shape, but rarely recorded in Poland. It was reported in eastern Poland by Tarkowska-Kukuryk & Kornijów (2008) in Lake Kleszczów and Tarkowska-Kukuryk (2014) in Lake Skomielno. The record of M. rydalensis in Rawka River is the first such case in central Poland. The species prefers littoral and sublittoral sediments of still water, but sporadically inhabits sediments or submerged mosses in running water (Andersen et al. 2013).

description: The de-regulation of microRNAs (miRNAs) is associated with multiple human diseases, yet cellular mechanisms governing miRNA abundance remain largely elusive. Human miR-122 is required for Hepatitis C proliferation, and low miR-122 abundance is associated with hepatic cancer. The adenylyltransferase Gld2 catalyses the post-transcriptional addition of a single adenine residue (A + 1) to the 3ʹ-end of miR-122, enhancing its stability. Gld2 activity is inhibited by binding to the Hepatitis C virus core protein during HepC infection, but no other mechanisms of Gld2 regulation are known. We found that Gld2 activity is regulated by site-specific phosphorylation in its disordered N-terminal domain. We identified two phosphorylation sites (S62, S110) where phosphomimetic substitutions increased Gld2 activity and one site (S116) that markedly reduced activity. Using mass spectrometry, we confirmed that HEK 293 cells readily phosphorylate the N-terminus of Gld2. We identified protein kinase A (PKA) and protein kinase B (Akt1) as the kinases that site-specifically phosphorylate Gld2 at S116, abolishing Gld2-mediated nucleotide addition. The data demonstrate a novel phosphorylation-dependent mechanism to regulate Gld2 activity, revealing tumour suppressor miRNAs as a previously unknown target of Akt1-dependent signalling.

description: Boson stars are descendants of the so-called geons of Wheeler, except that they are built from scalar particles instead of electromagnetic fields. If scalar fields exist in nature, such localized configurations kept together by their self-generated gravitational field can form within Einstein's general relativity. In the case of complex scalar fields, an absolutely stable branch of such non-topological solitons with conserved particle number exists. Our present surge stems from the speculative possibility that these compact objects could provide a considerable fraction of the non-baryonic part of dark matter. In any case, they may serve as a convenient "laboratory" for studying numerically rapidly rotating bodies in general relativity and the generation of gravitational waves.

description: The key issue in Dynamic Ensemble Selection (DES) is defining a suitable criterion for calculating the classifiers' competence. There are several criteria available to measure the level of competence of base classifiers, such as local accuracy estimates and ranking. However, using only one criterion may lead to a poor estimation of the classifier's competence. In order to deal with this issue, we have proposed a novel dynamic ensemble selection framework using meta-learning, called META-DES. An important aspect of the META-DES framework is that multiple criteria can be embedded in the system encoded as different sets of meta-features. However, some DES criteria are not suitable for every classification problem. For instance, local accuracy estimates may produce poor results when there is a high degree of overlap between the classes. Moreover, a higher classification accuracy can be obtained if the performance of the meta-classifier is optimized for the corresponding data. In this paper, we propose a novel version of the META-DES framework based on the formal definition of the Oracle, called META-DES.Oracle. The Oracle is an abstract method that represents an ideal classifier selection scheme. A meta-feature selection scheme using an overfitting cautious Binary Particle Swarm Optimization (BPSO) is proposed for improving the performance of the meta-classifier. The difference between the outputs obtained by the meta-classifier and those presented by the Oracle is minimized. Thus, the meta-classifier is expected to obtain results that are similar to the Oracle. Experiments carried out using 30 classification problems demonstrate that the optimization procedure based on the Oracle definition leads to a significant improvement in classification accuracy when compared to previous versions of the META-DES framework and other state-of-the-art DES techniques.

description: We examine an evolutionary model in which the primary source of "noise" that moves the model between equilibria is not random, arbitrarily improbable mutations but mistakes in learning. We find conditions under which the risk-dominant equilibrium in a 2 x 2 game is selected by the model as well as conditions under which the payoff-dominant equilibrium is selected. We also find that waiting times until the limiting distribution is reached can be shorter than in a mutation-driven model. We present comparative static results as well as a "two-tiered" evolutionary model in which the rules by which agents learn to play the game are themselves subject to evolutionary pressure.

description: Manifestations of activity on the YZ CMi (M4.5Ve) flare star which has a rotation period of 2.77 days and belongs to a group of activity-saturated stars, are considered from long-term photometric data together with photographic measurements from 1926 to 2009. Long-term changes in yearly mean brightness of the star are found on a time scale of 27.5 years with an amplitude of $0.2 - 0.3^m$ that indicate variations in development of surface inhomogeneities and a large degree of surface spottedness in the maximum activity. Spots are distributed unevenly over the surface, their concentration is higher at certain longitudes spaced by intervals equal to 0.6 phases of the rotation period. The recovery of active longitude (a possible "flip-flop" effect) occurs over a period of about 6 years. We note differences in activity of this star from typical for the Sun and solar-like stars, which are associated with its dynamic characteristics $P_{cyc}$ and $P_{rot}$ and its inner structure.

description: The past decade has been witness to immense progress in the understanding of the early stages of cluster formation both from a theoretical and observational perspective. During this time, samples of forming clusters at higher redshift, termed “proto-clusters”, once comprised of heterogeneous mix of serendipitous detections or detections arising from dedicated searches around rare galaxy populations, have begun to compete with lower-redshift samples both in terms of numbers and in the homogeneity of the detection methods. Much of this progress has come from optical/near-infrared (NIR) imaging and spectroscopic campaigns designed to target large numbers of typical galaxies to exquisite depth. In this poster I will focus on observations from VIMOS on VLT and MOSFIRE/DEIMOS on Keck, which have uncovered a large number of “proto-structures" at 2 < z < 5 that appear to resemble clusters and groups forming in the early universe. I will demonstrate the methods for finding, confirming, and characterizing proto-clusters and proto-groups in our sample. Several case studies of spectroscopically-confirmed massive proto-clusters with a diverse set of properties will be presented. I will finally present constraints on the relationship between star formation rate, stellar mass, and galaxy density at these redshifts.

description: This dissertation analyzes local and regional histories written during the 10th to 13th centuries in areas that were historically a part of the Persian Empire.  These texts are written in Persian or Arabic or both.  Some sources were originally in Arabic and later translated into Persian.  The main Persian language local histories that I will address in this dissertation include the Tarikh-i Sistan, Tarikh-i Tabaristan, Tarikh-i Bukhara, Tarikh-i Bayhaq, and Tarikh-i Qum. This project attempts to answer how and why Persian local and regional histories assert a privileged connection with the Prophet Muhammad.  I examine the ways in which Persian local and regional histories assert legitimacy, authority, and privileged access to Muhammad, the prophetic experience, and a blessed role in the Islamic umma.

description: We have measured the reflectivity spectra of the barium iridate $9R$ BaIrO$_3$, the crystal structure of which consists of characteristic Ir$_3$O$_{12}$ trimers. In the high-temperature phase above the transition temperature $T_c\simeq180$ K, we find that the optical conductivity involves two temperature-dependent optical transitions with an ill-defined Drude response. These features are reminiscent of the optical spectra in the organic dimer Mott insulators, implying a possible emergence of an unusual electronic state named trimer Mott insulator in BaIrO$_3$, where the carrier is localized on the trimer owing to the strong Coulomb repulsion. Along with a pronounced splitting of the phonon peak observed below $T_c$, which is a hallmark of charge disproportionation, we discuss a possible phase transition from the trimer Mott insulator to a charge-ordered insulating phase in BaIrO$_3$.

description: Senegal’s leading role in the development of African modernism in the 1960s is well known. Lesser-known is that, a century earlier, photography first arrived and took root in Senegal before circulating across French West Africa. This dissertation focuses on the genre of photographic portraiture in a country that did not have sculptural or masquerade traditions. It studies the ways in which photography accommodated and fostered new social and artistic practices and identities in Senegal between 1860—when the first studio opened in Saint Louis, the historical capital—and the 1960s, when photography became a “social imperative,” to use Geoffrey Batchen’s description (2001). The first chapter discusses cartes-de-visite commissioned as early as the 1860s by the first Senegalese patrons. In the course of this discussion, I challenge unilateral conceptions of photography as an apparatus of ideological control monopolized by the colonial authority. Chapter Two argues that Islam—the predominant religion in Senegal since the late nineteenth century—facilitated the popularity of the genre of portraiture through the circulation of devotional images in the form of lithographs, glass painting and photographs between the 1890s and 1920s. Chapter Three focuses on two photo series by amateur photographers from Saint Louis in the interwar period. I argue that these snapshots delineate the birth of a new subjectivity that neither mimicked French culture, nor conformed to Wolof customs. The last chapter juxtaposes the work of Mama Casset and Oumar Ka, two studio photographers working in the 1960s and 70s, in the capital and the rural interior of the country, respectively. In doing so I revisit the association between photography’s modernity and urban living, and propose that modernity can also be linked with “rural” tastes and styles. Rather than interpret it as either a “foreign” or “local” technology, this dissertation traces the fluctuations of photography’s significance in a dialectic relation with European, Islamic, American, African and Indian sources, revealing the nature of the medium as a multiplier of visions. Given Senegal's privileged status within La Grande France, this analysis will contribute to our understanding of the relationship between photography and modernity in Africa and beyond.

(Fig. 32C, D)
DESCRIPTION
 A tooth from the mammal material of Angeac-Charente, ANG M-34 (Fig. 32C, D), preserves a high, main central cusp, one accessory cusp and one root. Given the strong development of the accessory cusp and the inclination of the main cusp apex, this side of the tooth, and thus the only preserved root, is considered to be distal. The section of the tooth breakage shows that a second, mesial root was present. A symmetrical and similar accessory cusp was maybe present on the mesial side. Such morphology is reminiscent to that of the posterior premolariforms of the Middle Jurassic eutriconodont Amphilestes and other “ Amphilestidae ” (Kielan-Jaworowska et al. 2004). However, without the second half of the tooth, it is difficult to reach a conclusion, as it could also correspond to other, more derived mammals. Without any more diagnostic characters, this specimen is thus cautiously identified as Mammalia indet.

description: Piles used for oil platform foundation in Bohai Gulf, China, are usually over 100m long and 2m in diameter.Such long piles have to be manufactured in segments before installation because of transformation and hoistingdifficulties. The segments of the pile are assembled during installation by welding one to another, whichoften takes one or more days for two pile segments. After pile segment assembling, it proves to be difficult torestart the successive penetration. In this paper the mechanism of pile refusal is discussed and the process ofdriving a segmented pile is simulated using a finite element program. The calculated results show that whenthe stick-up stability is satisfied, increasing the length of the last segment of the pile and assembling the pilesegments when the pile tip stays in a clay layer can greatly ease the difficulty of restarting pile driving.

description: We propose an integrable system of coupled nonlinear Schrodinger equations with cubic-quintic terms describing the effects of quintic nonlinearity on the ultra-short optical soliton pulse propagation in non-Kerr media. Lax pair, conserved quantities and exact soliton solutions for the proposed integrable model are given. Explicit form of two-solitons are used to study soliton interaction showing many intriguing features including inelastic (shape changing) scattering. Another novel system of coupled equations with fifth-degree nonlinearity is derived, which represents vector generalization of the known chiral-soliton bearing system.

Un-traded Interdependencies' as a Useful Theory of Regional Economic Development:  a comparative study of innovation in Dublin and Beijing

description: The dissertation is an international comparative project examining metropolitan regional economic development. Focused on the connection between economic geography and economic learning, the study examines the locus of regional innovation in the information and communications technology (ICT) sector in each region (Dublin and Beijing) through small sample survey methodologies. An applied theory project, this dissertation relies on transaction cost and evolutionary economic theory to examine the micro-foundations of how regions are being touted for their "collective learning systems" and how this is an important aspect of understanding how rapid economic change occurs. Among some of the most influential arguments in this area are those often made by regional planners, industrial geographers, and economic sociologists which perceive of such dynamic regions as constituting a "nexus of un-traded interdependencies." Based on a small sample of twenty indigenous firms ICT firms in each region, the project takes aim at the often unspecified ways firm-specific capability development is argued to result from the interplay between industrial knowledge and issues of spatial clustering. Goal-seeing behavior of firms is seen through the lens of evolutionary notions of search, while transaction cost principles are regarded as fundamental to structuring pool effects, especially in labor supply and local knowledge pool issues linked to agglomerated industrial forms. Three inter-related propositions guide the analysis of the survey work. The first is that an assessment of how knowledge-based assets are developed through territorialized concepts of learning must focus on evolutionary properties of firm search strategies and differentiate between more and less advanced firms since they are likely to draw upon regional assets in different ways. The second is to examine the process of innovation itself in its traded and un-traded aspects by analyzing patterns in R&D decision-making, strategic networking, and contracting behavior. The third is how some seemingly similar development outcomes in each region are based in differentiated processes and modes of social regulation, and stresses the underlying conventions in social, political, and historical motivations of strategy and political economy constraints linking firm and industry developments to their broader institutional systems. This latter is centered on science and technology policy, on one hand, and urban redevelopment and governance of the property markets, on the other, and underscores the international comparative scope of the project.
