description: We report the discovery of a low-mass companion to HR3549, an A0V star surrounded by a debris disk with a warm excess detected by WISE at 22 $μ$m ($10σ$ significance). We imaged HR3549 B in the L-band with NAOS-CONICA, the adaptive optics infrared camera of the Very Large Telescope, in January 2013 and confirmed its common proper motion in January 2015. The companion is at a projected separation of $\simeq 80$ AU and position angle of $\simeq 157^\circ$, so it is orbiting well beyond the warm disk inner edge of $r > 10$ AU. Our age estimate for this system corresponds to a companion mass in the range 15-80 $M_J$, spanning the brown dwarf regime, and so HR3549 B is another recent addition to the growing list of brown dwarf desert objects with extreme mass ratios. The simultaneous presence of a warm disk and a brown dwarf around HR3549 provides interesting empirical constraints on models of the formation of substellar companions.

description: The 1920s marked a decade in the history of modern China which is typically referred to as the period of warlords. This period was characterised by political chaos, internal division and internecine warfare between various cliques of military strongmen who controlled China's numerous provinces. These de facto military dictators of China, known as warlords in historical literature, were customarily construed to be avaricious and self-serving despots who ruled their large territories with little regard for the welfare of their subjects or that of the Chinese nation. My thesis aims to revise these previously held assumptions concerning the historical agency of Chinese warlords by investigating the unusual conduct of a particularly influential warlord: Wu Peifu. Wu's display of deeply seated nationalistic tendencies throughout his political career, I argue, complicates our understanding of the impact that Chinese warlords exerted on the rise of Chinese national consciousness during the early 20th century.

description: The Koch snowflake is one of the first fractals that were mathematically described. It is interesting because it has an infinite perimeter in the limit but its limit area is finite. In this paper, a recently proposed computational methodology allowing one to execute numerical computations with infinities and infinitesimals is applied to study the Koch snowflake at infinity. Numerical computations with actual infinite and infinitesimal numbers can be executed on the Infinity Computer being a new supercomputer patented in USA and EU. It is revealed in the paper that at infinity the snowflake is not unique, i.e., different snowflakes can be distinguished for different infinite numbers of steps executed during the process of their generation. It is then shown that for any given infinite number~$n$ of steps it becomes possible to calculate the exact infinite number, $N_n$, of sides of the snowflake, the exact infinitesimal length, $L_n$, of each side and the exact infinite perimeter, $P_n$, of the Koch snowflake as the result of multiplication of the infinite $N_n$ by the infinitesimal $L_n$. It is established that for different infinite $n$ and $k$ the infinite perimeters $P_n$ and $P_k$ are also different and the difference can be infinite. It is shown that the finite areas $A_n$ and $A_k$ of the snowflakes can be also calculated exactly (up to infinitesimals) for different infinite $n$ and $k$ and the difference $A_n - A_k$ results to be infinitesimal. Finally, snowflakes constructed starting from different initial conditions are also studied and their quantitative characteristics at infinity are computed.

description: Multiphoton excitation of exogenous dyes and endogenous biochemical species has been used extensively for tissue diagnosis by fluorescence spectroscopy. Unfortunately, the majority of endogenous biochemical chromophores have low quantum yields, less than 0.2, therefore determining two-photon cross sections of weakly luminescencing molecules is difficult using two-photon fluorescence spectroscopy. Accurate determination of two-photon cross sections of these biochemicals could provide insight into fluorescence signal reduction caused by the absorption of excitation energy by non-target intracellular species. Non-resonant multiphoton photoacoustic spectroscopy (NMPPAS) is a novel technique we have developed for condensed matter measurements that has the potential for accurately determining two-photon absorption cross-sections of chemicals with small or non-existant fluorescence quantum yields. In this technique, near infrared light is used to generate an ultrasonic signal following a non-resonant two-photon excitation process. This ultrasonic wave is directly related to the non-radative relaxation of the chromophore of interest and is measured using a contact piezoelectric ultrasonic transducer. The signal from the ultrasonic transducer can then be used to calculate two-photon absorption cross sections. This paper will describe the validation of this technique by measuring the two-photon absorption cross- sections of well characterized chromophores such as rhodamine B and coumarin 1 in solution as well as riboflavin in a gelatin tissue phantom.

description: Optics East, 9-12 SEPTEMBER 2007, Boston, MA, United States
description: Gold-based surface-enhanced Raman scattering (SERS) beacons have been developed, which represent a simple, biocompatible and rapid means of performing multiplexed DNA sequence detection in a non-arrayed format. These SERS beacons consist of a simple stem-loop oligonucleotide probe in its native form with one end attached to a SERS active dye molecule and the other to a gold nanoparticle, approximately 50 nm in diameter. The probe sequence is designed to achieve a stem-loop structure, with the loop portion complementary to the target sequence, similar to fluorescent molecular beacons. In the absence of the target DNA sequence, the SERS signal of the associated dye molecule is detected, representing the "ON" state of the probe. When the target sequence is hybridized to the probe, which results in an open conformation, its respective reporter dye is separated from the gold nanoparticle, producing diminished SERS signal. In this paper, the fabrication and characterization of these SERS beacons is described. We also demonstrate selective hybridization of a target sequence to one beacon in a mixture, revealing their potential for use in a multiplexed fashion.

description: A multilayer surface-enhanced Raman scattering (SERS) substrate geometry providing significantly greater SERS enhancements, longer active lifetimes, better reproducibility, and lower detection limits for trace chemical analysis than traditional SERS substrates has been developed. We have fabricated and characterized this novel class of multilayered metal film-based SERS substrates, which are capable of enhancing SERS signals over an order of magnitude relative to conventional metal film over nanostructure substrates. These multilayer enhanced metal film substrates are fabricated by repeated vapor deposition of metal films over nanometer sized structures. Different sizes of nanostructures were evaluated in order to obtain the optimal SERS enhancements. Meanwhile, different dielectric coatings were fabricated between silver layers, and SERS enhancements were evaluated for each type. Additionally, different metals, such as gold, were used to further optimize the stability and reproducibility of these novel substrates. Silver oxide layers produced at elevated temperatures were also investigated to accelerate the fabrication rate of these multilayer substrates. Finally, this paper also discusses the application of these novel multilayer substrates for trace detection of chemical agents and simulants.

We extend previous analysis by characterizing the phenomenologically relevant parameter space and by constraining it using observations. Furthermore, we characterize the shape of LQC-corrections to observable quantities across this parameter space. Our analysis provides a framework to contrast more accurately the theory with forthcoming polarization data, and it also paves the road for the computation of other observables beyond the power spectra, such as non-Gaussianity.

description: We have investigated the ($2+1$)-dimensional variable coefficient coupled nonlinear Schrödinger equation (vc-CNLSE) in a graded-index waveguide. Similarity transformations are used to convert the vc-CNLSE into constant coefficient CNLSE. Under certain functional constraints we could extract semirational, multi-parametric solution of the associated Manakov system. This family of solutions include known Peregrine soliton, mixture of either bright soliton and rogue wave or dark soliton and rogue wave or breather and rogue wave. Under a distinct set of self-phase modulation (SPM) and cross-phase modulation (XPM) coefficients we could establish symbiotic existence of different soliton pairs as solutions. These soliton pairs may constitute of one bright and a dark soliton, two bright solitons or two dark solitons. Finally, when two wave components are directly proportional, we find bright and dark similaritons, self-similar breathers and rogue waves as different solutions.

description: Kaposis's sarcoma-associated Herpesvirus (KSHV) and Human Epstein-Barr virus (EBV) are gamma herpesviruses that can cause serious complications in immunocompromised patients. Quantitative detection is critical not only as a diagnostic tool in patients, but also as a method for basic herpesvirology research. Here the development and validation of four real-time PCR assays to quantify viral load of KSHV and EBV in samples is described. The assays are: individual viral load assays for KSHV and EBV, and high-throughput viral load screens for KSHV and EBV. The assays were developed for validation of animal models, drug response studies, basic virology research and medical diagnostics. The data indicate that these are accurate, consistent, and cost-effective assays for the detection of KSHV and EBV infection in various kinds of samples.

Label-free detection of antigens using implantable SERS nanosensors

description: Monitoring the presence, production and transport of proteins inside individual living cells can provide vital information about cellular signaling pathways and the overall biological response of an organism. For example, cellular response to external stimuli, such as biological warfare (BW) agents, can be monitored by measuring interleukin-II (IL-2) expression inside T-cells as well as other chemical species associated with T-cell activation. By monitoring such species, pre-symptomatic detection of exposure to BW agents can be achieved, leading to significantly increased post-exposure survival rates. To accomplish such monitoring, we have developed and optimized implantable nanosphere-based nanosensors for the intracellular analysis of specific proteins in a label-free fashion. These sensors consist of 300-520 nm diameter silica spheres that have been coated with silver and antibodies to allow for trace protein detection via surface enhanced Raman spectroscopy (SERS). They have been optimized for SERS response by evaluating the size of the nanospheres best suited to 632.8 nm laser excitation, as well as the various nanosensor fabrication steps (i.e., silver deposition process, antibody binding, etc.). During usage, the presence of the specific protein of interest is monitored by either directly measuring SERS signals associated with the protein and/or changes in the SERS spectrum of the antibodies resulting from conformational changes after antigen binding. In this work, human insulin was used as a model compound for initial studies into the sensitivity of these optimized nanosensors.

description: The early detection of biological warfare (BW) agents before any symptoms are present is critical for saving lives and reducing cost of therapy. Protein expression in T-cells represents one of the earliest detectable cellular signaling events to occur in response to the exposure to various toxins or BW agents. In order to fully understand a cellular response to a particular BW agent, it is often necessary to monitor the expression of specific proteins. Therefore, we have developed a novel class of surface enhanced Raman scattering (SERS) immuno-nanosensors for the real-time monitoring of protein expression within individual living cells. In this work, we have developed and optimized novel nanosphere-based silver coated SERS nanosensors for the detection of proteins at cellular levels. SERS nanosensors were optimized in terms of nanosphere size, silver coating methods, number of silver layers, antibody binding and affinity. These nanosensors are capable of being inserted into individual cells and non-invasively positioned to the sub-cellular location of interest using optical tweezers. They were constructed from monodisperse silica nanospheres. These nanospheres were condensed from tetraalkoxysilanes in an alcoholic solution of water and ammonia. Accurate control of the silica nanospheres’ diameter was achieved by varying the reaction conditions. Nanosphere-based SERS immuno-nanosensors were then prepared by depositing multiple layers of silver on silica spheres, followed by binding of the antibody of interest to the silver. In binding the antibodies, different cross linker agents were characterized and compared. On one end, each of these cross linker agents contained sulfur or isothiocyanate groups which bound to the silver surface, while the other end contained a carboxylic or primary amine group which reacted readily with the antibodies. In order to improve sensitivity of these nanosensors, optimal silver surface coverage with crosslinkers was determined. Following binding of antibodies, evaluation of the nanosensors was performed by monitoring the SERS spectra of the nanosensors prior to and following exposure to the antigen of interest. These results showed reproducible differences in the SERS spectra upon exposure to the antigens confirming their ability to monitor trace amounts of antigen. In particular, these SERS-based nanosensors were shown successfully detect human insulin at trace levels.

description: Superhydrophobic polymer films are a material of interest for aircraft deicing fluids to achieve the selfcleaning lotus effect. Hydrophobic polymer films were obtained by a solvent selective method composed of hydrophilic polymethylmethacrylate (PMMA) and hydrophobic polystyrene (PS) and hydrophilic titania nanoparticles. The addition of titania nanoparticles changed the surface of the thin films from an anisotropic morphology to a spherical isotropic surface due to hydrophobic and hydrophilic repulsion. Irradiation of UV responsive titania nanoparticles retained the same surface morphology. Water contact angle measurements will be completed to determine the hydrophobic nature of the polymer films.

description: Recent studies on multinary oxides for applications as laser hosts and high dielectric capacitors have shown that processing at high temperature provides glassy or crystalline materials based on thermal treatments and cooling rates. Since hydroxyapatites are now subject of great interests due to their bioactivity, interest in producing soft and hard materials with glassy and crystalline nature by processing parameters has become very important. Crystalline materials by using Bridgman, Czochralski and flux growth methods are costly and require huge investment. We have observed that even low temperature solidification in organic flux produced oriented fibers. This organic treated material has different characteristics than in situ oxide materials prepared by sintering and grain growth. Examples of phosphate and silicate-based systems will be presented to demonstrate soft and hard materials. Effect of TiO2 and other hardening elements will be also reported.

description: A groupoid is alternative if it satisfies the alternative laws $x(xy)=(xx)y$ and $x(yy)=(xy)y$. These laws induce four partial maps on $\mathbb{N}^+\times \mathbb{N}^+$, $(r,\,s)\mapsto (2r,\,s-r)$, $(r-s,\,2s)$, $(r/2,\,s+r/2)$, $(r+s/2,\,s/2)$ that taken together form a dynamical system. We describe the orbits of this dynamical system, which allows us to show that $n$th powers in a free alternative groupoid on one generator are well-defined if and only if $n\le 5$. We then discuss some number theoretical properties of the orbits, and the existence of alternative loops without two-sided inverses.

description: The formation of SMSs is a potential pathway to seed SMBHs in the early universe. A critical issue for forming SMSs is stellar UV feedback, which may limit the stellar mass growth via accretion. In this paper we study the evolution of an accreting SMS and its UV emissivity under conditions of realistic variable accretion from a self-gravitating circumstellar disc. First we conduct a 2D hydrodynamical simulation to follow the long-term protostellar accretion until the stellar mass exceeds $10^4~M_\odot$. The disc fragments due to gravitational instability, creating a number of small clumps that rapidly migrate inward to fall onto the star. The resulting accretion history is thus highly time-dependent: short episodic accretion bursts are followed by longer, relative quiescent phases. We show that the circumstellar disc for the so-called direct collapse model is more unstable and generates greater variability over shorter timescales than normal Pop III cases. We conduct a post-process stellar evolution calculation using the obtained accretion history. Our results show that, regardless of the strong variability of the accretion rates, the stellar radius monotonically increases with almost constant effective temperature at $T_{\rm eff} \simeq 5000$ K as the stellar mass increases. The resulting UV feedback is too weak to hinder mass accretion due to the low flux of stellar UV photons, thus verifying our implicit assumption of no stellar feedback during the hydrodynamic simulations. The insensitivity of stellar evolution to variable accretion is attributed to the fact that typical timescales of variability, $\lesssim 10^3$ years, are too short to affect the stellar structure. We argue that this evolution will continue until the SMS eventually collapses to produce a massive black hole by the general relativistic instability after the stellar mass reaches $\gtrsim 10^5~M_\odot$.

description: The development of novel culture-independent techniques of microbial identification has allowed a rapid progress in the knowledge of the nasopharyngeal microbiota and its role in health and disease. Thus, it has been demonstrated that the nasopharyngeal microbiota defends the host from invading pathogens that enter the body through the upper airways by participating in the modulation of innate and adaptive immune responses. The current COVID-19 pandemic has created an urgent need for fast-track research, especially to identify and characterize biomarkers to predict the disease severity and outcome. Since the nasopharyngeal microbiota diversity and composition could potentially be used as a prognosis biomarker for COVID-19 patients, which would pave the way for strategies aiming to reduce the disease severity by modifying such microbiota, dozens of research articles have already explored the possible associations between changes in the nasopharyngeal microbiota and the severity or outcome of COVID-19 patients. Unfortunately, results are controversial, as many studies with apparently similar experimental designs have reported contradictory data. Herein we put together, compare, and discuss all the relevant results on this issue reported to date. Even more interesting, we discuss in detail which are the limitations of these studies, that probably are the main sources of the high variability observed. Therefore, this work is useful not only for people interested in current knowledge about the relationship between the nasopharyngeal microbiota and COVID-19, but also for researchers who want to go further in this field while avoiding the limitations and variability of previous works.

description: Recently there is a big thrust on bio-inspired sensors and there has been a large rise in the investment and expectations for nanotechnology to meet these goals. For in situ sensor development materials deposition on substrate is essential part of device development. Physical vapor deposition (PVD), chemical vapor deposition (CVD) and molecular organic vapor deposition methods have developed for growth of semiconductor bulk and thin film growth with some modifications have been used for these materials. Oxides and other elements of VI group such as sulfides and selenides are key components in skins of many species. Growth of ordered structures containing these elements have been achieved by using PVD method. This paper describes effect of growth parameters during PVD growth on the quality of materials. Growth kinetics and mechanism will be discussed for the vertical and horizontal growth reactors. Since most of the efficient materials systems are multinary and in many cases noncongruent, PVD provides pathway to grow materials below melting temperature.

description: The requirement for solid, rigid structures for the ability to precisely control and manipulate acoustic waves can be highly limiting in applications such as biomedical imaging where sound manipulation and control through such interfaces cannot easily be employed. In this work, we describe the ability to generate optically induced reflective sound barriers and waveguides. These barriers are generated by creating abrupt density barriers via photothermal depletion of the transport medium along the path of a laser beam, causing sharp differences in compressibility, resulting in significant acoustic reflection. Using this technique, acoustic reflection efficiencies of 30% have been demonstrated. Furthermore, employing multiple optically induced acoustic reflective barriers sequentially can result in complete suppression of incident acoustic sound wave transmission. In addition to optically induced acoustic suppression, optical waveguiding can also be achieved using cylindrical, ring shaped laser beams. By containing the acoustic waves inside the cylindrical channel, dramatic improvements in acoustic transmission can be achieved. Optical waveguding of acoustic signals offers a new paradigm in the manipulation of sound over extended distances in various media, providing potentially significant improvements to photoacoustic sensing and imaging in many applications

description: The process for the formation of kidney stone is very complex phenomena and has some similarity to the crystal growth from a solution. It is very much dependent on the acidity pH of the fluids. This pH variation affects the content and amount of filtering residue and its morphology. In this study we have performed experiments using carbonate, oxides and urea to simulate and understand the morphologies of the residue filtered and coarsened in different conditions. We observed that different of morphologies of kidney stones can be explained on the basis of acidity and hydration conditions. At lower pH fat prism crystals are observed and as pH increases, long fat needle crystals with large aspect ratio are observed. The coarsening experiments showed further growth of crystals. The remelting experiments showed that during dissolution of kidney stones the joining material breaks first leaving the large faceted crystals undissolved when attempts are made to dissolve into small crystallites.However, the morphology did not change. It was also observed that impurities such as magnesium oxide (MgO) affect the morphology significantly.
Replication: psychometric curves analysis of an online vigilance task

description: Fitting psychometric curves to vigilance data using hierarchical Bayesian modeling, McCarley and Yamani (in press) found that the vigilance decrement was driven by a sensitivity loss, conservative bias shift, and increase in attentional lapse rate. The present study is an attempt to replicate these results in an online sample. Pilot data gave evidence of a conservative bias shift and very large increase in lapse rate, but no evidence for or against a change in sensitivity. Differences between the pilot results and McCarley and Yamani's results could be due, in part, to participants not fully attending to the task when completing it in an uncontrolled setting. In an attempt to minimize effects of this, we will recruit paid participants from Prolific for the pre-registered replication, rather than relying on undergraduate participant pools.

description: Semiconductor nanowires exhibit very exciting optical and electrical properties including high transparency and a several order of magnitude better photocurrent than thin film and bulk materials. We present here the mechanism of nanowire growth from the melt-liquid-vapor medium. We describe preliminary results of binary and ternary selenide materials in light of recent theories. Experiments were performed with lead selenide and thallium arsenic selenide systems which are multifunctional material and have been used for detectors, acoustooptical, nonlinear and radiation detection applications. We observed that small units of nanocubes and elongated nanoparticles arrange and rearrange at moderate melt undercooling to form the building block of a nanowire. Since we avoided the catalyst, we observed self-nucleation and uncontrolled growth of wires from different places. Growth of lead selenide nanowires was performed by physical vapor transport method and thallium arsenic selenide nanowire by vapor-liquid-solid (VLS) method. In some cases very long wires (>mm) are formed. To achieve this goal experiments were performed to create situation where nanowires grew on the surface of solid thallium arsenic selenide itself.
