description: We report direct visualization of gigahertz-frequency Lamb waves propagation in aluminum nitride phononic circuits by transmission-mode microwave impedance microscopy (TMIM). Consistent with the finite-element modeling, the acoustic eigenmodes in both a horn-shaped coupler and a sub-wavelength waveguide are revealed in the TMIM images. Using fast Fourier transform filtering, we quantitatively analyze the acoustic loss of individual Lamb modes along the waveguide and the power coupling coefficient between the waveguide and the parabolic couplers. Our work provides insightful information on the propagation, mode conversion, and attenuation of acoustic waves in piezoelectric nanostructures, which is highly desirable for designing and optimizing phononic devices for microwave signal processing and quantum information transduction.

description: This thesis entitled Ortus, for chamber ensemble, interactive electronics, and motion tracking, establishes a novel approach to spectral composition. It is scored for flute/alto flute, clarinet/bass clarinet, bassoon, piano, percussion, violin 1, violin 2, viola, cello, and real-time electronics. A conceptual narrative transforms the abstract spectral data into a story telling device through the inherent meaning and semantic implications of the chosen sound files. Ortus relies on the recording and analysis of a heartbeat as its foundation; the heartbeat is used as the musical material for the three tutti movements, with extracted pitch material used to create formal and conceptual cohesion between all of the movements. Additionally, two conceptually different sound file families are integrated, which form the basis for the small ensemble movements and are used for the creation of all pitch, structural, and formal materials.

description: We present a new harmonic-domain approach for extracting morphological information, in the form of Minkowski Functionals (MFs), from weak lensing (WL) convergence maps. Using a perturbative expansion of the MFs, which is expected to be valid for the range of angular scales probed by most current weak-lensing surveys, we show that the study of three generalized skewness parameters is equivalent to the study of the three MFs defined in two dimensions. We then extend these skewness parameters to three associated skew-spectra which carry more information about the convergence bispectrum than their one-point counterparts. We discuss various issues such as noise and incomplete sky coverage in the context of estimation of these skew-spectra from realistic data. Our technique provides an alternative to the pixel-space approaches typically used in the estimation of MFs, and it can be particularly useful in the presence of masks with non-trivial topology. Analytical modeling of weak lensing statistics relies on an accurate modeling of the statistics of underlying density distribution. We apply three different formalisms to model the underlying dark-matter bispectrum: the hierarchical ansatz, halo model and a fitting function based on numerical simulations; MFs resulting from each of these formalisms are computed and compared. We investigate the extent to witch late-time gravity-induced non-Gaussianity (to which weak lensing is primarily sensitive) can be separated from primordial non-Gaussianity and how this separation depends on source redshift and angular scale.

description: A new strain of coronavirus (CoV) has been identified as SARS-CoV-2, which is responsible for the recent COVID-19 pandemic. Currently, there is no approved vaccine or drug available to combat the pandemic. COVID-19 main protease (Mpro) is a key CoV enzyme, which plays an important role in triggering viral replication and transcription, turns it into an attractive target. Therefore, we aim to screen natural products library to find out potential COVID-19 Mpro inhibitors. Plant-based natural compounds from Sigma-Aldrich plant profiler chemical library have been screened through virtual molecular docking and molecular dynamics simulation to identify potential inhibitors of COVID Mpro. Our virtual molecular docking results have shown that there are twenty-eight natural compounds with a greater binding affinity toward the COVID-19 Mpro inhibition site as compared to the co-crystal native ligand Inhibitor N3 (-7.9 kcal/mol). Also, molecular dynamics simulation results have confirmed that Peonidin 3-O-glucoside, Kaempferol 3-O-β–rutinoside, 4-(3,4-Dihydroxyphenyl)-7-methoxy-5-[(6-O-β-D-xylopyranosyl-β-D-glucopyranosyl)oxy]-2H-1-benzopyran-2-one, Quercetin-3-D-xyloside, and Quercetin 3-O-α-L-arabinopyranoside (selected based on the docking score) possess a significant amount of dynamic properties such as stability, flexibility and binding energy. Our In silco results suggests that all the above mention natural compounds have the potential to be developed as a COVID-19 Mpro inhibitor. But before that, it must go through under the proper preclinical and clinical trials for further scientific validation. Communicated by Ramaswamy H. Sarma

description: Heutzutage vollzieht sich der börsliche Handel rein faktisch durch Buchungen zwischen (digitalen) Depots, ohne dass physische Wertpapierurkunden ausgetauscht werden. So nimmt es Wunder, dass elektronische Wertpapiere dem in Deutschland geltenden Recht lange fremd waren. Denn in Deutschland bildet das Sachenrecht, welches nur Rechte an körperlichen, jedoch nicht an unkörperlichen Gegenständen anerkennt, die rechtliche Basis zur Übertragung von Wertpapieren. Dies trägt dem Umstand Rechnung, dass Rechte nach wie vor in Papierurkunden verkörpert sind, um den sachenrechtlichen Übereignungsgrundsätzen zu unterfallen und damit den für den Rechtsverkehr wichtigen Gutglaubensschutz zu gewährleisten. Im Zuge der Einführung computergestützter Arbeitsabläufe und der fortschreitenden Digitalisierung führte der Gesetzgeber die Möglichkeit ein, statt der einzelnen Wertpapierurkunden lediglich eine über eine gesamte Emission ausgestellte Globalurkunde zentral zu verwahren. Andere Länder sind in diesem Bereich seit geraumer Zeit weiter. In Frankreich und in der Schweiz beispielsweise sind rein elektronische Wertpapiere — sogenannte Wertrechte — schon seit längerem gesetzlich geregelt. Deutschland hat erst kürzlich mit dem Gesetz zur Einführung von elektronischen Wertpapieren nachgezogen, welches am 10. Juni 2021 in Kraft getreten ist. Die Dissertation analysiert die bisherige Rechtslage hinsichtlich der Übertragungsmöglichkeiten klassischer sowie in Globalur-kunden verbriefter Wertpapiere.

description: The largest amplitude light curves for both RR Lyrae (RRL) variables and classical Cepheids with periods less than 10 days and greater than 20 days occur at the blue edge of the respective instability strips. It is shown that the equation for the decrease in amplitude with penetration into the strip from the blue edge, and hence the amplitude fine structure within the strip, is the same for RRL and the Cepheids despite their metallicity differences. However, the manifestation of this identity is different between the two classes of variables because the sampling of the RRL strip is restricted by the discrete strip positions of the horizontal branch, a restriction that is absent for the Cepheids in stellar aggregates with a variety of ages. To show the similarity of the strip amplitude fine structure for RRL and Cepheids we make a grid of lines of constant amplitude in the HR diagram of the strip using amplitude data for classical Cepheids in the Galaxy, LMC, and SMC. The model implicit in the grid, that also contains lines of constant period, is used to predict the correlations between period, amplitude, and color for the two Oosterhoff RRL groups in globular clusters. The good agreement of the predictions with the observations using the classical Cepheid amplitude fine structure also for the RRL shows one aspect of the unity of the pulsation processes between the two classes of variables.

description: Metal-insulator-semiconductor (MIS) structures are widely used in Si-based solar water- splitting photoelectrodes to protect the Si layer from corrosion. Typically, there is a tradeoff between efﬁciency and stability when optimizing insulator thickness. Moreover, lithographic patterning is often required for fabricating MIS photoelectrodes. In this study, we demon- strate improved Si-based MIS photoanodes with thick insulating layers fabricated using thin- ﬁlm reactions to create localized conduction paths through the insulator and electro- deposition to form metal catalyst islands. These fabrication approaches are low-cost and highly scalable, and yield MIS photoanodes with low onset potential, high saturation current density, and excellent stability. By combining this approach with a p +n-Si buried junction, further improved oxygen evolution reaction (OER) performance is achieved with an onset potential of 0.7 V versus reversible hydrogen electrode (RHE) and saturation current density of 32 mA/cm 2 under simulated AM1.5G illumination. Moreover, in stability testing in 1 M KOH aqueous solution, a constant photocurrent density of ~22 mA/cm 2 is maintained at 1.3 V versus RHE for 7 days.

description: To comprehend the molecular mechanism of zinc transportation by bacteria tends to be a very complicated and time-consuming method. To date, fragmented and scanty studies are available about the mechanism of zinc transportation at molecular level. So, the present study scrutinizes in silico pathways of zinc fractions transportation, specifically in Bacillus spp. stimulating dynamic performance of zinc. For this, the constructed model reveals Zur to be the prime regulatory transport protein maintaining bacterial survivability at fluctuation in zinc concentrations, thereby attaining zinc homeostasis. Topology for hub nodes displays appropriate evidence of the molecular basis of bacterial zinc imports and exports. Further, the molecular docking reveals interaction of Zur protein with the zinc ligands (ZnCO3 and ZnSO4). By validation of binding affinity, binding energy and docking score via Autodock Vina and X-Score, the ZnSO4 compound was found to possess excellent stability in the active pocket site of Zur, stating Zur-ZnSO4 complex to be the most potential. Owing to which, the Zur-ZnSO4 complex was selected and subjected to molecular dynamics simulation, revealing RMSD, RG, RMSF, SASA and interaction energy for 20 ns trajectory period. Henceforth,the study provides novel insight into revealing the unrecognized Zur protein pathway, assisting zinc transportation, besides retaining best interaction with ZnSO4 ligand. This is the first system biology where molecular docking and molecular dynamics simulation-based investigation decipher the role of Zur transport protein system and interaction of its amino acids with zinc ligands in a simpler and economical form via in silico techniques.

description: Previously developed analytic models for the evolution of cosmic string and monopole networks are applied to networks of monopoles attached to two or more strings; the former case is usually known as cosmic necklaces. These networks are a common consequence of models with extra dimensions such as brane inflation. Our quantitative analysis agrees with (and extends) previous simpler estimates, but we will also highlight some differences. A linear scaling solution is usually the attractor solution for both the radiation and matter-dominated epochs, but other scaling laws can also exist, depending on the universe's expansion rate and the network's energy loss mechanisms.

description: Using general arguments of an optimization taking place between the pair wave function and the repulsive part of the electron-electron interaction, we analyze the superconducting gap in materials with multiple Fermi-surface (FS) pockets, with exemplary application to two proto-type ferropnictide setups. On the basis of functional renormalization group (FRG) calculations for a wide parameter span of the bare interactions, we show that the symmetry of the gap and the nodal versus nodeless behavior is driven by this optimization requirement.

description: When a core collapse supernova occurs in a binary system, the surviving star as well as the compact remnant emerging from the SN, may reach a substantial space velocity. With binary population synthesis modelling at solar and one fifth of solar metallicity, we predict the velocities of such runaway stars or binaries. We compile predictions for runaway OB stars, red supergiants and Wolf-Rayet stars. For those stars or binaries which undergo a second stellar explosion we compute their further evolution and the distance travelled until a Type II or Type Ibc SN or a long or short gamma-ray burst occurs. We find our predicted population of OB runaway stars broadly matches the observed population of stars but, to match the fastest observed WR runaway stars, we require that black holes receive an asymmetric kick upon formation. We find that at solar metallicity Type Ic SN progenitors travel shorter distances than the progenitors of other SN types because they are typically more massive and thus have shorter lifetimes. Those of Type IIP SN can fly farthest about 48 pc on average at solar metallicity. In considering the consequences of assuming that the progenitors of long GRBs are spun-up secondary stars that experience quasi-homogeneous evolution, we find that such evolution has a dramatic effect on the population of runaway WR stars and that some 30 per cent of GRBs could occur a hundred parsecs or more from their initial positions. We also consider mergers of double compact object binaries consisting of neutron stars and/or black holes. We find the most common type of visible mergers are neutron star--black hole mergers that are roughly ten times more common than neutron star--neutron star mergers. We also find that there may be a population of low-velocity neutron stars that are ejected from a binary rather than by their own natal kick.

description: In November 1918, massive popular unrest broke out in the Hungarian countryside, followed by a short but intense borderland war against the Czechoslovakian and Romanian army. Meanwhile, from the spring of 1919, red and white paramilitary groups terrorized the countryside, killing hundreds of people. This violent post-war transformation lasted until 1921 and made a significant mark on the interwar political culture of the country. The so called “Szeged Idea,” the founding myth of the right-wing paramilitaries of 1919-1920, became the dominant ideology in interwar Hungary. Miklós Horthy’s regime defined itself as “counterrevolutionary,” the antithesis of the revolutionary democratic and communist governments. This, however, did not mean that all the right-wing paramilitary figures had a direct pathway to power in the interwar period and that all of Béla Kun’s military leaders were completely sidelined. These people had various careers and some – but not all – of them were involved in right-wing movements and actively participated in the mass murders of World War II.

description: The targeted compounds which are Schiff base derivatives were prepared by reaction of 6-(4-phenyl-piperazin-1-yl)pyridine-3-ylamine with 2-hydroxy and 2,6-dichloro benzaldehyde. These compounds were isolated, purified and then spectrally characterized via FT-IR, 1H and 13C NMR, LC MS TOF, and TGA analysis where strong proofs confirmed the formation of the targeted product. The biological activity, which is pancreatic porcine lipase inhibition, of the compounds was investigated and Orlistat was used as standard drug. The compound 3 was found to be as potent as orlistat against PL enzyme with an IC50 value of 0.50 μM. The molecular docking studies were performed for both obtained compounds and orlistat against active side of porcine pancreatic lipase. Also, MM/PBSA binding free energy and molecular dynamics (MD) simulation analyzes were performed for pancreatic porcine lipase with compound 3, which showed potent inhibition according to the results of in vitro studies. Furthermore, The ADME and toxicity analysis of the compounds were examined using web-based online platforms, SwissADME and pkCSM. In the light of biological activity and in silico studies, the compound 3 can be a potential drug candidate with further studies. Communicated by Ramaswamy H. Sarma

title: First order conservation law framework for large strain explicit contact dynamics
Creators: name: Runcie, Callum John
Publisher: name: University of Glasgow
Year: 2023

description: This thesis presents a novel vertex-centred finite volume algorithm for explicit large strain solid contact dynamic problems where potential contact loci are known a priori. This methodology exploits the use of a system of first order conservation equations written in terms of the linear momentum and a triplet of geometric deformation measures, consisting of the deformation gradient tensor, its co-factor and its determinant, in combination with their associated Rankine-Hugoniot jump conditions. These jump conditions are used to derive several dynamic contact models ensuring the preservation of hyperbolic characteristic structure across solution discontinuities at the contact interface, which is a significant advantage over standard quasi-static contact models where the influence of inertial effects at the contact interface is completely neglected. By taking advantage of this conservative formalism, both kinematic (velocity) and kinetic (traction) contact-impact conditions are explicitly enforced at the fluxes through the use of the appropriate jump conditions. Specifically, the kinetic contact condition was enforced, in the traditional manner, through the linear momentum equation, while the kinematic contact condition was easily enforced through the geometric conservation equations without requiring a computationally demanding iterative scheme. Additionally, a Total Variation Diminishing shock capturing technique can be suitably incorporated in order to improve dramatically the performance of the algorithm at the vicinity of shocks, importantly no ad-hoc regularisation procedure is required to accurately capture shock phenomena. Moreover, to guarantee stability from the spatial discretisation standpoint, global entropy production is demonstrated through the satisfaction of semi-discrete version of the classical Coleman-Noll procedure expressed in terms of the time rate of the Hamiltonian energy of the system. Finally, a series of numerical examples is presented in order to assess the performance and applicability of the proposed algorithm suitably implemented across MATLAB and a purpose built OpenFOAM solver.

description: Osmolytes are known to stabilize proteins against denaturing conditions. Ethylene glycol (EG), however, shows a distinctive effect on α-lactalbumin (α-LA) that it stabilizes the protein against cold-induced denaturation, whereas it destabilizes during heat denaturation. The replica exchange molecular dynamics (REMD) simulation of α-LA in the presence of EG shows that EG denatures the protein at higher temperatures whereas it retards the denaturation at sub-zero temperature. Representative structures of α-LA were selected from REMD trajectories at three different temperature conditions (240, 300 and 340 K) with and without EG, and classical molecular dynamics (MD) simulations were performed. The results suggest that the presence of water around α-LA is more at lower temperatures; however, water around the hydrophobic residues is reduced with the addition of EG at sub-zero temperature. The partition coefficient of EG showed that the binding of EG with hydrophobic residues was higher at lower temperatures. Preferential interaction parameters at different temperatures were calculated based on the mean distribution (Γ23) and Kirkwood–Buff integral (G23) methods. Γ23 shows a larger positive value at 240 K compared to higher temperatures. G23 shows positive values at lower temperatures, whereas it becomes negative at above 280 K. These results indicate that the preferential binding of EG with α-LA is more at sub-zero temperature compared to higher temperature conditions. Thus, the study suggests that the preferential binding of EG reduces the hydrophobic hydration of α-LA at lower temperatures, and stabilizes the protein against cold denaturation. However, the preferential binding of EG at higher temperature drives the folding equilibrium towards the denatured state. Communicated by Ramaswamy H. Sarma
Shaping video experiences with new interface affordances

description: Watching and creating videos have become predominant parts of our daily lives. Video is becoming the norm for a wide range of purposes from entertainment, to training and education, marketing, and communication. Users go beyond just watching videos. They want to experience and interact with content across the different types of videos. As they do so, significant digital traces accumulate on the viewed videos which provide an important source of information for designing and developing tools for video viewing interfaces. This dissertation proposes the next generation video management interface which creates video experiences that go beyond just pushing the play button. It uses how people view and interact with contemporary video to design strategies for future video interfaces. This has allowed the development of new tools for navigating and managing videos that can be easily integrated into existing systems. To help define some design guidelines for the video interface, a behavioural analysis of users’ video viewing actions (n = 19) was performed. The results demonstrate that participants actively watch videos and most participants tend to skip parts of videos and re-watch specific portions from a video multiple times. Based on the findings, new fast navigation and management strategies are developed and validated in search tasks using a single-video history (n = 12), a video viewing summary (n = 10) and multiple-videos history (n = 10). Evaluation of results of the proposed tools show significant performance improvements over the state-of-the-practice methods. This indicates the value of users’ video viewing actions. Navigating other forms of videos, such as interactive videos, introduces another issue with the selection of interactive objects within videos to direct users to different portions of the video. Due to the time-based nature of the videos, these interactive objects are only visible for a certain duration of the video, which makes their activation difficult. To alleviate this problem a novel acquisition technique (Hold) is created, which temporally pauses the objects while the user interacts with the target. This technique has been integrated into a rich media interface (MediaDiver) which made such interaction possible for users.

description: We present non-linear dynamical features of two-photon double-cavity optical bistability exhibited by a three level ladder system in the mean field limit. The system exhibits a hump like feature in the lower branch of the bistable response, wherein a new region of instability develops. The system displays a range of dynamical features varying from normal stable switching, periodic self-pulsing to a period-doubling route to chaos. The inclusion of two competing cooperative atom-field couplings leads to such rich nonlinear dynamical behavior. We provide a domain map that clearly delineates the various regions of stability that will aid the realization of any desired dynamics. We also present bifurcation diagram and the associated supporting evidence that clearly identifies the period-doubling route to chaos, which occurs at low input light levels.

description: The leading face of Saturn's moon Iapetus, Cassini Regio, has an albedo only one tenth that on its trailing side. The origin of this enigmatic dichotomy has been debated for over forty years, but with new data, a clearer picture is emerging. Motivated by Cassini radar and imaging observations, we investigate Soter's model of dark exogenous dust striking an originally brighter Iapetus by modeling the dynamics of the dark dust from the ring of the exterior retrograde satellite Phoebe under the relevant perturbations. In particular, we study the particles' probabilities of striking Iapetus, as well as their expected spatial distribution on the Iapetian surface. We find that, of the long-lived particles (greater than about 5 microns), most particle sizes (greater than about 10 microns) are virtually certain to strike Iapetus, and their calculated distribution on the surface matches up well with Cassini Regio's extent in its longitudinal span. The satellite's polar regions are observed to be bright, presumably because ice is deposited there. Thus, in the latitudinal direction we estimate polar dust deposition rates to help constrain models of thermal migration invoked to explain the bright poles (Spencer & Denk 2010). We also analyze dust originating from other irregular outer moons, determining that a significant fraction of that material will eventually coat Iapetus--perhaps explaining why the spectrum of Iapetus' dark material differs somewhat from that of Phoebe. Finally we track the dust particles that do not strike Iapetus, and find that most land on Titan, with a smaller fraction hitting Hyperion. As has been previously conjectured, such exogenous dust, coupled with Hyperion's chaotic rotation, could produce Hyperion's roughly isotropic, moderate-albedo surface.

description: We summarize the higher-loop perturbative computation of the ghost and gluon propagators in SU(3) Lattice Gauge Theory. Our final aim is to compare with results from lattice simulations in order to expose the genuinely non-perturbative content of the latter. By means of Numerical Stochastic Perturbation Theory we compute the ghost and gluon propagators in Landau gauge up to three and four loops. We present results in the infinite volume and $a \to 0$ limits, based on a general fitting strategy.

description: Ushbu maqolada ingliz va o‘zbek tillaridagi so‘z turkumlari tasnifining kategoriyaviy-grammatik asoslarini kognitiv va tipologik yondashuvlar nuqtai nazaridan o‘rganishga bag‘ishlangan. Tadqiqot davomida ikki tilning morfologik tuzilmalari, sintaktik imkoniyatlari va semantik-pragmatik xususiyatlari asosida so‘z turkumlarining shakllanishi, o‘zgaruvchanligi va kontekstual moslashuv darajasi qiyosiy tahlil qilinadi. Ingliz tilining analitik-flektiv tabiati va o‘zbek tilining aglutinativ xususiyatlari asosida har bir tilga xos bo‘lgan kategoriya modeli ochib beriladi. Ayniqsa, konversiya, funksional siljish, affiksal differensiyatsiya va paradigma barqarorligi kabi lingvistik hodisalar orqali so‘z turkumlari tizimidagi umumiylik va tafovutlar chuqur yoritiladi. Tadqiqot natijalari tilshunoslikdagi universal va tipologik kategoriya tushunchasini kengaytirishga xizmat qiladi. Natijalar ingliz va o‘zbek tillarini o‘rganishda, shuningdek, kontrastiv tilshunoslik tadqiqotlarida muhim ahamiyatga ega bo‘lishi mumkin.

description: We present the implementation of a three-dimensional, second order accurate Godunov-type algorithm for magneto-hydrodynamic (MHD), in the adaptive-mesh-refinement (AMR) cosmological code {\tt CHARM}. The algorithm is based on the full 12-solve spatially unsplit Corner-Transport-Upwind (CTU) scheme. The fluid quantities are cell-centered and are updated using the Piecewise-Parabolic-Method (PPM), while the magnetic field variables are face-centered and are evolved through application of the Stokes theorem on cell edges via a Constrained-Transport (CT) method. The multidimensional MHD source terms required in the predictor step for high-order accuracy are applied in a simplified form which reduces their complexity in three dimensions without loss of accuracy or robustness. The algorithm is implemented on an AMR framework which requires specific synchronization steps across refinement levels. These include face-centered restriction and prolongation operations and a {\it reflux-curl} operation, which maintains a solenoidal magnetic field across refinement boundaries. The code is tested against a large suite of test problems, including convergence tests in smooth flows, shock-tube tests, classical two- and three-dimensional MHD tests, a three-dimensional shock-cloud interaction problem and the formation of a cluster of galaxies in a fully cosmological context. The magnetic field divergence is shown to remain negligible throughout.

description: The outbreak of novel coronavirus disease (COVID-19) caused by SARS-CoV-2 poses a serious threat to human health and world economic activity. There is no specific drug for the treatment of COVID-19 patients at this moment. Traditionally, people have been using spices like ginger, fenugreek and onion, etc. for the remedy of a common cold. This work identifies the potential inhibitors of the main protease (Mpro) and spike (S) receptor of SARS-CoV-2 from 10 readily available spices. These two proteins, S and Mpro, play an important role during the virus entry into the host cell, and replication and transcription processes of the virus, respectively. To identify potential molecules an in-house databank containing 1040 compounds was built-up from the selected spices. Structure-based virtual screening of this databank was performed with two important SARS-CoV-2 proteins using Glide. Top hits resulted from virtual screening (VS) were subjected to molecular docking using AutoDock 4.2 and AutoDock Vina to eliminate false positives. The top six hits against Mpro and top five hits against spike receptor subjected to 130 ns molecular dynamic simulation using GROMACS. Finally, the compound 1-, 2-, 3- and 5-Mpro complexes, and compound 17-, 18-, 19-, 20- and 21- spike receptor complexes showed stability throughout the simulation time. The ADME values also supported the drug-like nature of the selected hits. These nine compounds are available in onion, garlic, ginger, peppermint, chili and fenugreek. All the spices are edible and might be used as home remedies against COVID-19 after proper biological evaluation. Communicated by Ramaswamy H. Sarma

description: Since the 1970's, when the Viking spacecrafts carried out experiments aimed to the detection of microbial metabolism on the surface of Mars, the search for nonspecific methods to detect life in situ has been one of the goals of astrobiology. It is usually required that the methodology can detect life independently from its composition or form, and that the chosen biological signature points to a feature common to all living systems, as the presence of metabolism. In this paper we evaluate the use of Microbial Fuel Cells (MFCs) for the detection of microbial life in situ. MFCs are electrochemical devices originally developed as power electrical sources, and can be described as fuel cells in which the anode is submerged in a medium that contains microorganisms. These microorganisms, as part of their metabolic process, oxidize organic material releasing electrons that contribute to the electric current, which is therefore proportional to metabolic and other redox processes. We show that power and current density values measured in MFCs using microorganism cultures or soil samples in the anode are much larger than those obtained using a medium free of microorganisms or sterilized soil samples, respectively. In particular, we found that this is true for extremophiles, usually proposed to live in extraterrestrial environments. Therefore, our results show that MFCs have the potential to be used to detect microbial life in situ.

The targum (1875:Feb.)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1875

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.
