Canonical Quantum Statistics of an Isolated Schwarzschild Black Hole with a Spectrum E_n = sigma sqrt{n} E_P

description: Many authors - beginning with Bekenstein - have suggested that the energy levels E_n of a quantized isolated Schwarzschild black hole have the form E_n = sigma sqrt{n} E_P, n=1,2,..., sigma =O(1), with degeneracies g^n. In the present paper properties of a system with such a spectrum, considered as a quantum canonical ensemble, are discussed: Its canonical partition function Z(g,beta=1/kT), defined as a series for g<1, obeys the 1-dimensional heat equation. It may be extended to values g>1 by means of an integral representation which reveals a cut of Z(g,beta) in the complex g-plane from g=1 to infinity. Approaching the cut from above yields a real and an imaginary part of Z. Very surprisingly, it is the (explicitly known) imaginary part which gives the expected thermodynamical properties of Schwarzschild black holes: Identifying the internal energy U with the rest energy Mc^2 requires beta to have the value (in natural units) beta = 2M(lng/sigma^2)[1+O(1/M^2)], (4pi sigma^2=lng gives Hawking's beta_H), and yields the entropy S=[lng/(4pi sigma^2)] A/4 + O(lnA), where A is the area of the horizon.

The 'Maradona' of the Economy: The Rise and Fall of Cavallo's Integrated Argentine Economy
Creators: Servideo, Lucas
Publisher: name: Columbia University
Year: 2014
Subjects: Latin Americans

description: In early 1991, ten years before Argentina defaulted on its international debt and devalued its currency, an effort was made to address the economic crisis caused by runaway inflation. The subsequent decade, that is the years after 2000, saw the failure of the policies then put in place and marks one of the most tragic periods in the country’s economic history. During the 90s, the country underwent ‘neoliberal’ market reforms centered on open trade and access to capital markets, fiscal responsibility, and a stable currency.  According to Joseph Stiglitz, a Nobel Prize winner in the field of economics and author of Argentina, short-changed: Why the nation that followed the rules fell to pieces, the policies implemented during the 1990s were doomed to fail. The most influential piece of the policy reforms was the convertibility law, which equated the Argentine peso with the US Dollar.  Maintaining this exchange parity was of the utmost importance to the country at the time and depended on two measures: the sale of state assets and international borrowing.
In this thesis I will study the relationship between these two policies through an analysis of Domingo Cavallo’s account, Argentina’s economic minister from 1991 to 1995. By examining his speeches, articles and interviews, and by studying the process of selling state assets in it of itself, I argue that the minister believed that privatization made access to capital markets possible. The story I am telling and my analysis of it obviously have a deeper history that is essentially social and political, but this thesis does not try to place the policies or Cavallo himself in that history except by implication. Instead, I am focusing on the monetary and fiscal history itself: how privatization worked, how it made it possible for Argentina to borrow in international markets; to the extent possible from published data, I am also assessing the extent to which the combination of privatization and borrowing actually worked to restore fiscal health – and when it no longer did.

description: Suppose that a compound Poisson process is observed discretely in time and assume that its jump distribution is supported on the set of natural numbers. In this paper we propose a non-parametric Bayesian approach to estimate the intensity of the underlying Poisson process and the distribution of the jumps. We provide a MCMC scheme for obtaining samples from the posterior. We apply our method on both simulated and real data examples, and compare its performance with the frequentist plug-in estimator proposed by Buchmann and Grübel. On a theoretical side, we study the posterior from the frequentist point of view and prove that as the sample size $n\rightarrow\infty$, it contracts around the `true', data-generating parameters at rate $1/\sqrt{n}$, up to a $\log n$ factor.

description: Cyanobacteria are a promising biological chassis for the synthesis of renewable fuels and chemical bulk commodities. Significant efforts have been devoted to improve the yields of cyanobacterial products. However, while the introduction and heterologous expression of product-forming pathways is often feasible, the interactions and incompatibilities of product synthesis with the host metabolism are still insufficiently understood. In this work, we investigate the stoichiometric properties and trade-offs that underlie cyanobacterial product formation using a computational reconstruction of cyanobacterial metabolism. First, we evaluate the synthesis requirements of a selection of cyanobacterial products of potential biotechnological interest. Second, the large-scale metabolic reconstruction allows us to perform in silico experiments that mimic and predict the metabolic changes that must occur in the transition from a growth-only phenotype to a production-only phenotype. Applied to the synthesis of ethanol, ethylene, and propane, these in silico transition experiments point to bottlenecks and potential modification targets in cyanobacterial metabolism. Our analysis reveals incompatibilities between biotechnological product synthesis and native host metabolism, such as shifts in ATP/NADPH demand and the requirement to reintegrate metabolic by-products. Similar strategies can be employed for a large class of cyanobacterial products to identify potential stoichiometric bottlenecks.
The 'Ins' and 'Outs' of the Bushveld Complex Upper Zone

Year: 2011
Subjects: subject: Petrology
subject: Geochemistry
subject: FOS: Earth and related environmental sciences

description: This dissertation is an investigation into the geochemical and geodynamic evolution of the Upper Zone of the Bushveld Complex. The Bushveld Complex is one of the few large layered intrusions in which the entire cumulate stratigraphy is preserved and well-exposed from its base to its roof. Despite this unique feature, relatively little is known about the nature of magmatic differentiation in the uppermost portions of the Bushveld. As a first order, I quantify the chemical composition of the preserved stratigraphy (i.e. the bulk composition) from the geochemical base of the Upper Zone (the Pyroxenite Marker) to the contact with the roof. On the basis of major element modeling and trace element equilibria I show that the bulk composition is not representative of the original magma composition, and therefore some magma must be missing. I propose that the Rooiberg Group lavas and/or Rashoop granophyres, which make up the immediate roof of the intrusion, represent the missing magma. A further test of the magma-loss hypothesis comes from the trace element contents of apatites in the uppermost 625 m of the Upper Zone stratigraphy. Comparison of the equilibrium liquid compositions calculated from these apatites with the Rooiberg and/or Rashoop roof rocks shows that they are a geochemical match. My results also indicate a role for large-scale (>625 m) liquid immiscibility at the top of the Bushveld. This is the first documented evidence for liquid immiscibility based on the compositions of mineral phases, not melt inclusions; and it is the first quantitative evidence for large-scale immiscibility in the Bushveld Complex. Quantification of the parent magma composition at the Pyroxenite Marker allows me to not only estimate the `outputs' from the magma chamber, but also to constrain the `inputs'. A geochemical record of magma input and mixing is recorded in the cumulate stratigraphy for approximately 350 m below the Pyroxenite Marker. Using the evolution in mineral compositions I calculate the composition and proportion of incoming magma to the Upper Zone, as well as the style of input. The composition of the incoming magma is then compared to other known pulses of magma into the Bushveld Complex in order to put constraints on the source contributions and formation dynamics of the intrusion as a whole.

description: The existence of continuous not necessarily bounded solutions of nonlinear functional Volterra integral inclusions in infinite dimensional setting is shown with the aid of the measure of nonequicontinuity. New abstract topological fixed point results for admissible condensing operators are introduced. Weak compactness criterion in the space of locally integrable functions in the sense of Bochner is set forth. Some examples illustrating the usefulness of the presented approach are also included.

description: We study the differential decay rate for the rare decay $Λ_b\to Λ(1520)(\to NK)\ell^+\ell^-$ where $\ell$ is a light lepton, as this decay mode can provide new and complementary constraints on the Wilson coefficients in $b\to s\ell^+\ell^-$ transitions compared to other modes. We provide a determination of the complete angular distribution, assuming unpolarised $Λ_b$ baryons and neglecting the lepton mass. The resulting angular observables are expressed in terms of helicity amplitudes involving hadronic form factors within the Standard Model and New physics models with chirality-flipped operators. We study these observables at low and large $Λ$ recoils, using effective theories to determine relations among the hadronic form factors involved. As there is currently no determination of the form factors available from lattice simulations or light-cone sum rules, we perform a first illustration of the sensitivity of some observables to New Physics contributions using hadronic inputs from quark models.

description: The most abundant biological particles in the atmosphere are pollen grains and spores. Self protection of pollen allergy is possible through the information of future pollen contents in the air. In spite of the importance of airborne pol len concentration forecasting, it has not been possible to predict the pollen concentrations with great accuracy, and about 25% of the daily pollen forecasts have resulted in failures. Previous analysis of the dynamic characteristics of atmospheric pollen time series indicate that the system can be described by a low dimensional chaotic map. We apply the wavelet transform to study the multifractal characteristics of an a irborne pollen time series. We find the persistence behaviour associated to low pollen concentration values and to the most rare events of highest pollen co ncentration values. The information and the correlation dimensions correspond to a chaotic system showing loss of information with time evolution.

description: This dissertation focuses on the consequences of considering social networks in standard frameworks in political economy and political methodology. The first paper introduces a game theoretic model where an allocator may distribute benefits over a social network, but the units in the network may extract rents from the allocator. This amendment to a classic allocation game generates unique predictions. Units can use their social position to extract rents and corruption persists in equilibrium. This has major implications for the provision of local public goods. The second paper derives a general statistical framework for causal identification in randomized experiments in the presence of spillovers. The paper addresses a major question in the analysis of randomized experiments and develops a framework that can be readily applied by practitioners. The third paper analyzes the impact of kinship networks on political preference formation in rural India. It is shown that kinship networks help to pool information, generate political discussion and provide explicit coordination of political behavior. This provides an account of how social structure functions in democratic developing country contexts.

description: The theoretical evaluation of major nuclear structure effects on the asymmetry of allowed Gamow-Teller beta-decay rates in light mirror nuclei is presented. The calculations are performed within the shell model, using empirical isospin-nonconserving interaction and realistic Woods-Saxon radial wave functions. The revised treatment of p-shell nuclei is supplemented by systematic calculations for sd-shell nuclei and compared to experimental asymmetries when available. The results are important in connection with the possible existence of second-class currents in the weak interaction.

The "Total Campaign": How Ronald Reagan Overwhelmingly Won the California Gubernatorial Election of 1966
Creators: McKenna, Kevin
Publisher: name: Columbia University
Year: 2010
Subjects: History

description: While many historians have discussed Reagan's victory in the 1966 California gubernatorial election as a major turning point in American politics, they have nearly exclusively attributed Reagan's victory to a backlash against racial violence and leftist antagonism. While some have acknowledged the skillful management of his campaign, few have emphasized its centrality to Reagan's electoral success. I examined a variety of campaign materials at the Ronald Reagan Presidential Library and a few oral histories of campaign officials and politicians to explain how Reagan defeated Pat Brown, an effective two-term governor who embodied "responsible liberalism" in the age of the Great Society. Regan's campaign team, led by political consultants Stu Spencer and Bill Roberts, innovated many new campaign techniques that have shaped American electioneering in subsequent decades, first showing conservatives how to win popular support after the overwhelming defeat of Barry Goldwater in the presidential contest held just two years earlier. The Reagan campaign effectively organized a massive army of volunteers, who reached out to voters in every corner of the state on the candidate's behalf. They also hired behavioral scientists, advertisers, and film producers to engineer an image of Ronald Reagan as a "citizen politician" fighting big government in defense of the common man. The combination of an all-encompassing media strategy with an unprecedented recruitment and deployment of grassroots activists produced a "total campaign" that launched Reagan's political career and made modern conservatism a legitimate, mainstream political ideology.

description: Conducting a tailings dam breach assessment (TDBA) is an important step in emergency preparedness and response planning. Following the occurrences of high-profile failure incidents, a multi-institution research project, called CanBreach, was started in 2019 to improve the state-of-the-art in TDBA practice. The University of Waterloo, through a four-year doctoral program, led the detailed statistical and remote sensing (i.e., satellite-based GIS and InSAR) components of the CanBreach project, with the central goal of enhancing case history knowledge. There were three main objectives in this doctoral program: 1. Understand the background hazard-risk: estimate the number of tailings dams to quantify the historical failure rate, in comparison to water-retention dams for context. 2. Map the consequences: geospatial analysis of archived satellite imagery and compilation of case history data to develop new empirical relations for tailings dam failures. 3. Evaluate modern solutions: application of Sentinel-1 InSAR technology, including multiple processing algorithms, to a ground-truth test site for comparison to monitoring prism data, and to several forensic case study sites to check if failures could have been predicted in advance. The purpose of this paper is to summarize the main contributions resulting from this doctoral program. The outcomes included: 1) a representative estimate of the number of tailings dams worldwide; 2) new insights into magnitude-frequency and failure statistics; 3) new case history databases of tailings dam failures and tailings flows supplemented with satellite images; and 4) a better understanding of the capabilities and limitations of Sentinel-1 InSAR for monitoring tailings dams. These contributions have implications for the hazard and risk assessment of tailings dams.

description: This dissertation argues that the waters of the English Channel and North Sea constituted a coherent region of political, geographical, and human life in the late sixteenth and early seventeenth centuries. It examines a large corpus of manuscript and printed maps, sea-charts, portolan charts, navigation manuals, and other works of geography to determine what the Channel was named, when, and by whom, demonstrating how nomenclature and systems of toponyms were wielded as political tools by nationalist cartographers. It traces changes in how the region was known and represented over two centuries, and how cartographic practices and sailing technology shifted along with those changes, to the benefit of domestic and overseas trade and nascent empire-building for England, France, and the Netherlands. It posits the existence of at least two ‘maritime states’ on and next to Channel waters, as the Dutch Sea Beggars and the Brittany port town of Saint-Malo sought to carve out nationhood for themselves based almost solely on the deployment of marine power. Finally, it considers how events and experiences in the Channel can inform and support current developments in the field of the ‘blue humanities.’ Many aspects of the work seek to complicate, and in some places to undermine, the common truism that ‘knowledge is power,’ asking what representations of knowledge might have produced what sort(s) of power on early modern European maps.
Plasmon Resonances and Tachyon Ghost Modes in Highly Conducting Sheets

description: Plasmon-polariton modes in two-dimensional electron gases have a dual field-matter nature that endows them with unusual properties when electrical conductivity exceeds a certain threshold set by the speed of light. In this regime plasmons display an interesting relation with tachyons, the hypothetical faster-than-light particles. While not directly observable, tachyons directly impact properties of plasmon modes. Namely, in the ``tachyon'' regime, plasmon resonances remain sharp even when the carrier collision rate $γ$ exceeds plasmon resonance frequency. Resonances feature a recurrent behavior as $γ$ increases, first broadening and then narrowing and acquiring asymmetric non-Lorentzian lineshapes with power-law tails extending into the tachyon continuum $ω>ck$. This unusual behavior can be linked to the properties of tachyon poles located beneath $ω>ck$ branch cuts in the complex $ω$ plane: as $γ$ grows, tachyon poles approach the light cone and hybridize with plasmons. Narrow resonances persisting for $γ>ω$, along with the unusual density and temperature dependence of resonance frequencies, provide clear signatures of the tachyon regime.

Mit Hilfe einer Kombination von Modellen auf der Basis der Molekulardynamik und der zellulären Automaten erscheint es möglich, die Bildung innerer Strukturen während der Verformungsvorgänge, die das makroskopische Verhalten wesentlich beeinflussen, numerisch zu simulieren.
description: The macroscopic behaviour of cristalline materials under mechanical or thermal loadings is determined by processes in the micro-region of the material. The stochastical character of these mechanisms can be considered by modelling them as stochastic processes which result in Markovchains.
By a combination of models on the basis of molecular dynamics and cellular automata it seems possible to simulate numerically the formation of internal structures during the deformation processes which influence the macroscopical behaviour substantially.
Quantum tetrahedra and simplicial spin networks

description: A new link between tetrahedra and the group SU(2) is pointed out: by associating to each face of a tetrahedron an irreducible unitary SU(2) representation and by imposing that the faces close, the concept of quantum tetrahedron is seen to emerge. The Hilbert space of the quantum tetrahedron is introduced and it is shown that, due to an uncertainty relation, the ``geometry of the tetrahedron'' exists only in the sense of ``mean geometry''. A kinematical model of quantum gauge theory is also proposed, which shares the advantages of the Loop Representation approach in handling in a simple way gauge- and diff-invariances at a quantum level, but is completely combinatorial. The concept of quantum tetrahedron finds a natural application in this model, giving a possible intepretation of SU(2) spin networks in terms of geometrical objects.

description: We study the kinetics of phase transitions in a Rayleigh-Benard system after onset of convection using 2D Swift-Hohenberg equation. An initially uniform state evolves to one whose ground state is spatially periodic. We confirmed previous results which showed that dynamical scaling occurs at medium quench ($ε= 0.25$) with scaling exponents 1/5 and 1/4 under zero noise and finite noise respectively. We find logarithmic scaling behavior for a deep quench ($ε= 0.75$) at zero noise. A simple method is devised to measure the proxy of domain wall length. We find that the energy and domain wall length exhibit scaling behavior with the same exponent. For $ε= 0.25$, the scaling exponents are 1/4 and 0.3 at zero and finite noise respectively.

The (Re)Birth of Off-Broadway

description: Commercial Off-Broadway is dead…or so we!ve been told again and again.
Since the turn of the last century, there have been countless articles bemoaning
the state of commercial Off-Broadway, and the word among today!s industry
insiders is not a whole lot better. This bleak picture wasn!t always the case,
though. There was a time in the not so distant past when Off-Broadway not only
existed, but thrived – and not solely as a dumping ground for Broadway-branded
shows or event-based spectacles. Off-Broadway served as a home for
productions that were considered inappropriate for Broadway and showcased
provocative work and emerging talent. It provided a rigorous training ground for
young producers, artists and writers, hoping to break into the professional world.
Off-Broadway also offered a way to present these exciting works with less money
at risk than a Broadway production – and many of these productions even made
a profit. At some point in the very recent past, however, things for Off-Broadway
changed. The possibility of profit or even recoupment became a much larger
struggle and as a result commercial productions started to dwindle. This paper
will explore the history of Off-Broadway and what the terrain is like today. It will
look at the reasons commercial Off-Broadway lost its footing and what it can do
to regain its relevance to the New York City theatre scene. It will also consider if
commercial Off-Broadway is worth revitalizing and if not, what could replace it.

description: Chaos ist das Wort mit der weltweit größten Wertsteigerung, so schrieb DER SPIEGEL, Brügge (1993), am Beginn seiner dreiteiligen Serie "Kult um das Chaos" mit dem Untertitel "Aberglaube oder Welterklärung?". In dieser Serie finden sich viele harsche Worte für die unseriösen Protagonisten der Chaostheorie. Viele erliegen in der Tat der Faszination prächtig falscher "Chaosdarstellungen".
Viele reden und schreiben über die Chaostheorie: Mathematiker und Physiker, Ingenieure und Biochemiker, Ökologen und Mediziner und sogar Sozialwissenschaftler. Und wenn soviele darüber reden, dann ist es nicht erstaunlich, daß sogar Komponisten, Dichter, Tänzer, Psychologen und auch Manager davon angesteckt werden. Wenn soviele darüber reden, dann ist es klar, daß nicht alle, die es tun, auch etwas davon verstehen. Aber sie tun es trotzdem, und damit sind wir beim Problem. Chaostheorie beschreibt keine "wissenschaftliche Revolution". Der Begriff "Chaostheorie" erweckt genauso falsche Assoziationen wie der Begriff "Katastrophentheorie".
Mit dem Artikel "Chaos, Fraktale und das Bild der Mathematik in der Öffentlichkeit" stellt der Mathematiker Steffen (1994) sehr kritisch Beiträge zur Chaostheorie an den Pranger. Man muß seine Wertung nicht teilen, sie mag vielen gar provokativ überzogen vorkommen, aber er hat sicher manche besonders verwegene Deutungen, Spekulationen und Auswüchse zu Recht aufs Korn genommen.
Das Thema Chaos hat viele Facetten und so auch die dazu erschienenen Publikationen. Die Bandbreite an umfangreicher, lesenswerter Literatur deutscher Autoren aus dem Bereich der Ingenieurwissenschaften reicht von Argyris u. a. (1994) bis Straub (1990).
Ich will mich heute weder mit Steffens zum Teil beißender Kritik beschäftigen und auch nicht in den Kreis leidenschaftlicher Befürworter einreihen, sondern über meine nunmehr über fünfzehnjährige Erfahrung mit dem Thema "Chaostheorie" berichten.
Für den Tübinger Biochemiker Otto Rössler ist der altgriechische Philosoph Anaxagoras der Urvater der Chaostheorie. Das könnte ein Beleg dafür sein, daß Chaos die Menschheit schon lange beschäftigt. Auch Leonardo da Vinci war von diesem Phänomen offenbar fasziniert, wie einige seiner Zeichnungen erahnen lassen. Ich befinde mich also in guter Gesellschaft!

The 1994 International Conference on Population and Development: A Turning Point in the Evolution of Women’s Reproductive Rights

description: The definition for reproductive rights was laid out in the 1994 International Conference on Population and Development (ICPD) Program of Action, and remains the standard definition for these guarantees and freedoms. This definition of reproductive rights begins with those rights related to health. Indeed, health often serves as a point of access for the advancement of these rights at the international level, and several of the components of reproductive rights were first recognized through the right to health. This paper will begin its examination of reproductive rights through the selective rights of women enumerated in the right to the highest attainable standard of health. This paper will examine in detail the years immediately preceding and following the ICPD, as well as characteristics of the conference that set it apart from prior, or contemporary international activities. In the two decades following the conference, the international community has maintained its commitment to the Conference goals, which have added relevance to the Millennium Development Goals (MDGs). In the 21st century, the international community has also begun to explore sexual rights, a development that would not have been possible without the ICPD.

description: Global U(1) strings with cylindrical symmetry are studied in anti-de Sitter spacetime. According as the magnitude of negative cosmological constant, they form regular global cosmic strings, extremal black cosmic strings and charged black cosmic strings, but no curvature singularity is involved. The relationship between the topological charge of a neutral global string and the black hole charge is clarified by duality transformation. Physical relevance as straight string is briefly discussed.

The (Mis)application of the Western Concept of “Resilience” to Non-Western Crises: South Sudanese Women as Case Study

description: This thesis involves an analysis of how the term “resilience” is mobilized and operationalized by groups and organizations that tout human rights as a main concern; I look to the relaying of South Sudanese women’s experiences to social justice workers as a case study, aiming to gain perspective from the women’s narratives of resilience. The purpose of this research is largely to critically engage with and question the resilience framework often referenced and taken for granted within modern human rights discourse. Qualitative research was conducted via interviews with eight individuals who have experience working with the South Sudanese population. Findings included five major themes: (1) the emphasis on social support and religiosity in South Sudanese culture, (2) a glaring lack of psychosocial services for traumatized refugees, (3) a trend toward pushing education for impact, (4) a leaning toward self-identifying as “survivor” among South Sudanese women, and (5) the futility of the resilience framework in non-Western contexts such as within South Sudan and the diaspora. I conclude that the resilience framework not only misses the mark when applied to non-Western contexts, such as humanitarian and human rights efforts have erroneously applied it to South Sudanese women and their experiences of conflict-related gender-based violence, but that the application of this framework in this way may even be considered to be a dangerous application.

description: Network reliability measures the probability that a target node is reachable from a source node in an uncertain graph, i.e., a graph where every edge is associated with a probability of existence. In this paper, we investigate the novel and fundamental problem of adding a small number of edges in the uncertain network for maximizing the reliability between a given pair of nodes. We study the NP-hardness and the approximation hardness of our problem, and design effective, scalable solutions. Furthermore, we consider extended versions of our problem (e.g., multiple source and target nodes can be provided as input) to support and demonstrate a wider family of queries and applications, including sensor network reliability maximization and social influence maximization. Experimental results validate the effectiveness and efficiency of the proposed algorithms.

description: Following the release in August 2020 of the Global Industry Standard on Tailings Management (Tailings Standard), prepared jointly by the International Council on Mining and Metals (ICMM), United Nations Environment Programme (UNEP), and Principles for Responsible Investment (PRI), ICMM members and some other mining companies have committed to implement its principles. While the level of information that an owner develops for specific Tailings Standard requirements may vary depending on the lifecycle stage of a specific tailings storage facility (TSF), the overall conformance process is similar throughout. TSFs that are demonstrated to be in “safe closure”, as confirmed by an Independent Technical Review Board or Senior Independent Technical Reviewer, are not subject to the Tailings Standard. This paper outlines the process Freeport-McMoRan1 has taken to achieve safe closure status, as defined by the Tailings Standard, for a set of closed TSFs in Arizona. Freeport-McMoRan has robust internal reclamation and post-reclamation monitoring and surveillance programs. Over the past twenty years, Freeport-McMoRan has established a proactive assessment and review process that has been undertaken across its portfolio. This includes Tailings Stewardship Team (TST) inspections and action item follow-up, appointment of Engineers of Record, and active engagement of Independent Technical Review Boards (ITRBs). The work completed through this ongoing process provided the basis for the determination of safe closure status for the set of closed TSFs. This process and the lessons learned from demonstrating safe closure status are outlined in this paper.

description: Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disorder characterized by the dysfunction and death of motor neurons. Patients afflicted with this condition commonly experiences muscle weakness that progresses to generalized paralysis. Although most ALS cases are sporadic, mutations in several human genes of divergent molecular function have been linked to the development of ALS. Recently, two new ALS genes, TDP-43 and FUS, were identified that have structural similarities suggesting that they may function in a common process. TDP-43 and FUS have both been implicated in a number of cellular functions, including the regulation of splicing, transcription, and microRNA processing. The work in this thesis includes studies that identified roles for TDP-43 and FUS in the health and function of the nervous system of Drosophila melanogaster. Genetic and biochemical studies were used to define the molecular relationships between TDP-43 and FUS, placing TDP-43 upstream of FUS in a common pathway that is important for the function and health of the nervous system. The finding that TDP-43 and FUS interact suggests that they regulate a common disease pathway that is disrupted in ALS and that therapeutic intervention in this pathway may ameliorate many of the symptoms of the disease.

description: In a group $G$, a weak Sierpiński subset is a subset $E$ such that for some $g,h\in G$ and $a\neq b\in E$, we have $gE=E\smallsetminus \{a\}$ and $hE=E\smallsetminus \{b\}$. In this setting, we study the subgroup generated by $g$ and $h$, and show that it has a special presentation, namely of the form $G_k=\langle g,h\mid (h^{-1}g)^k\rangle$ unless it is free over $(g,h)$. In addition, in such groups $G_k$, we characterize all weak Sierpiński subsets.
