description: The purpose of this note is to introduce a new approach to the study of one of the most basic and seemingly intractable problems in partition theory, namely the conjecture that the partition function $p(n)$ is equidistributed modulo 2. Our main result will relate the densities, say $δ_t$, of the odd values of the $t$-multipartition functions $p_t(n)$, for several integers $t$. In particular, we will show that if $δ_t>0$ for some $t\in \{5,7,11,13,17,19,23,25\}$, then (assuming it exists) $δ_1>0$; that is, $p(n)$ itself is odd with positive density. Notice that, currently, the best unconditional result does not even imply that $p(n)$ is odd for $\sqrt{x}$ values of $n\le x$. In general, we conjecture that $δ_t=1/2$ for all $t$ odd, i.e., that similarly to the case of $p(n)$, all multipartition functions are in fact equidistributed modulo 2. Our arguments will employ a number of algebraic and analytic methods, ranging from an investigation modulo 2 of some classical Ramanujan identities and several other eta product results, to a unified approach that studies the parity of the Fourier coefficients of a broad class of modular form identities recently introduced by Radu.

description: The Kepler Space Telescope is currently searching for planets transiting stars along the ecliptic plane as part of its extended K2 mission. We processed the publicly released data from the first year of K2 observations (Campaigns 0, 1, 2, and 3) and searched for periodic eclipse signals consistent with planetary transits. Out of 59,174 targets we searched, we detect 234 planetary candidates around 208 stars. These candidates range in size from gas giants to smaller than the Earth, and range in orbital periods from hours to over a month. We conducted initial reconnaissance spectroscopy of 68 of the brighter candidate host stars, and present high resolution optical spectra for these stars. We make all of our data products, including light curves, spectra, and vetting diagnostics available to users online.

description: Given a finite group $G$, we introduce the \textit{permutability degree} of $G$, as $$pd(G)=\frac{1}{|G| \ |\mathcal{L}(G)|} {\underset{X \in \mathcal{L}(G)}\sum}|P_G(X)|,$$ where $\mathcal{L}(G)$ is the subgroup lattice of $G$ and $P_G(X)$ the permutizer of the subgroup $X$ in $G$, that is, the subgroup generated by all cyclic subgroups of $G$ that permute with $X\in \mathcal{L}(G)$. The number $pd(G)$ allows us to find some structural restrictions on $G$. Successively, we investigate the relations between $pd(G)$, the probability of commuting subgroups $sd(G)$ of $G$ and the probability of commuting elements $d(G)$ of $G$. Proving some inequalities between $pd(G)$, $sd(G)$ and $d(G)$, we correlate these notions.

Decision Analysis of Incineration Costs in Superfund Site Remediation
Creators: name: Perdek, Joyce M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1993

description: This paper examines the decision making process of the Remedial Design (RD) phase of on-site incineration projects conducted at Superfund sites. Decisions made during RD affect the cost and schedule of the remedial action (RA). Decision analysis techniques are used to determine the extent of information on the waste characteristics that should be released to prospective bidders on a fixed-price RA contract for a specific site. The decision maker has two alternatives: to prepare the project specifications including only the description of the waste provided in the remedial investigation/feasibility study or obtain additional information on the waste characteristics during RD. The dilemma facing decision makers is that costs, in both time and money, are associated with acquiring additional information, while having more information may result in cost savings since bidders base their cost estimates on the description of the waste characteristics. In the analysis, the net benefits of providing bidders with additional information are determined for the subject site. The results show that the benefits of obtaining information outweigh the costs only when the cost of obtaining the information is not too great.

description: Although improvements in radiation therapy were made over the years, radioresistance is still a major challenge. Cancer cells are often deficient for DNA repair response, a feature that is currently exploited as a new anti-cancer strategy. In this context, combination of inhibitors targeting complementary pathways is of interest to sensitize cells to radiation. In this work, we used PARP (Olaparib) and RAD51 (B02) inhibitors to radiosensitize cancer cells to proton and X-ray radiation. More particularly, Olaparib and B02 were used at concentration leading to limited cytotoxic (alone or in combination) but increasing cell death when the cells were irradiated. We showed that, although at limited concentration, Olaparib and B02 were able to radiosensitize different cancer cell lines, i.e. lung and pancreatic cancer cells. Antagonistic, additive or synergistic effects were observed and correlated to cell proliferation rate. The inhibitors enhanced persistent DNA damage, delayed apoptosis, prolonged cell cycle arrest and senescence upon irradiation. These results demonstrated that radiation-induced synthetic lethality might widen the therapeutic window, hence extending the use of PARP inhibitors to patients without BRCAness.

Is there a computable upper bound on the heights of rational solutions of a Diophantine equation with a finite number of solutions?

Publisher: name: arXiv

Subjects: subject: Number Theory (math.NT)

subject: 11U05

description: The height of a rational number $p/q$ is denoted by $h(p/q)$ and equals $\text{max}(|p|,|q|)$ provided p/q is written in lowest terms. The height of a rational tuple $(x_1,...,x_n)$ is denoted by $h(x_1,...,x_n)$ and equals $\text{max}(h(x_1),...,h(x_n))$. Let $G_n={x_i+1=x_k: i,k \in {1,...,n}} \cup {x_i \cdot x_j=x_k: i,j,k \in {1,...,n}}$. Let $f(1)=1$, and let $f(n+1)=2^{(2^{(f(n))})}$ for every positive integer n. We conjecture: (1) if a system $S \subseteq G_n$ has only finitely many solutions in rationals $x_1,...,x_n$, then each such solution $(x_1,...,x_n)$ satisfies $h(x_1,...,x_n) \leq {1 (\text{if} n=1), 2^{(2^{(n-2)})} (\text{if} n>1)}$; (2) if a system $S \subseteq G_n$ has only finitely many solutions in non-negative rationals $x_1,...,x_n$, then each such solution $(x_1,...,x_n)$ satisfies $h(x_1,...,x_n) \leq f(2n)$. We prove: (1) both conjectures imply that there exists an algorithm which takes as input a Diophantine equation, returns an integer, and this integer is greater than the heights of rational solutions, if the solution set is finite; (2) both conjectures imply that the question whether or not a given Diophantine equation has only finitely many rational solutions is decidable by a single query to an oracle that decides whether or not a given Diophantine equation has a rational solution.

description: In 1990 Bender, Canfield and McKay gave an asymptotic formula for the number of connected graphs on $[n]=\{1,2,\ldots,n\}$ with $m$ edges, whenever $n\to\infty$ and $n-1\le m=m(n)\le \binom{n}{2}$. We give an asymptotic formula for the number $C_r(n,m)$ of connected $r$-uniform hypergraphs on $[n]$ with $m$ edges, whenever $r\ge 3$ is fixed and $m=m(n)$ with $m/n\to\infty$, i.e., the average degree tends to infinity. This complements recent results of Behrisch, Coja-Oghlan and Kang (the case $m=n/(r-1)+Θ(n)$) and the present authors (the case $m=n/(r-1)+o(n)$, i.e., `nullity' or `excess' $o(n)$). The proof is based on probabilistic methods, and in particular on a bivariate local limit theorem for the number of vertices and edges in the largest component of a certain random hypergraph. The arguments are much simpler than in the sparse case; in particular, we can use `smoothing' techniques to directly prove the local limit theorem, without needing to first prove a central limit theorem.

description: Efforts to search for better treatment options for cancer have been a priority, and due to these efforts, new alternative therapies have emerged. For instance, clinically relevant tumor-suppressive microRNAs that target key oncogenic drivers have been identified as potential anti-cancer therapeutics. MicroRNAs are small non-coding RNAs that negatively regulate gene expression at the posttranscriptional level. Aberrant microRNA expression, through misexpression of microRNA target genes, can have profound cellular effects leading to a variety of diseases, including cancer. While altered microRNA expression contributes to a cancerous state, restoration of microRNA expression has therapeutic benefits. For example, ectopic expression of microRNA-34a (miR-34a), a tumor suppressor gene that is a direct transcriptional target of p53 and thus is reduced in p53 mutant tumors, has clear effects on cell proliferation and survival in murine models of cancer. MicroRNA replacement therapies have recently been tested in combination with other agents, including other microRNAs, to simultaneously target multiple pathways to improve the therapeutic response. Thus, we reasoned that other microRNA combinations could collaborate to further improve treatment. To test this hypothesis miR-34a was used in an unbiased cell-based approach to identify combinatorial microRNA pairs with enhanced efficacy over miR-34a alone. This approach identified a subset of microRNAs that was able to enhance the miR-34a antiproliferative activity. These microRNA combinatorial therapeutics could offer superior tumor-suppressive abilities to suppress oncogenic properties compared to a monotherapeutic approach. Collectively these studies aim to address an unmet need of identifying, characterizing, and therapeutically targeting microRNAs for the treatment of cancer.

description: This project examines the role of grip strength on the risk of cardiovascular disease by first investigating the hypothesis relating to the cause and effect relationship between grip strength and cardiovascular disease, and then investigating whether grip strength is not rather a marker of frailty which modifies and / or mediates the existing associations between cardiovascular risk factors and cardiovascular disease. We investigate these hypotheses from a perspective of differences between men and women. This project therefore specifically aims to: (i) Examine grip strength as a prognostic risk factor for the cardiovascular condition of the elderly, taking into account the differences between men and women; (ii) Investigate the associations between grip strength and cardiovascular diseases, taking into account the differences between men and women; and (iii) Investigate the potential role of effect modifier and grip strength mediator in existing associations between vascular risk factors and cardiovascular disease.

Northeast Creek TMDL: The Health and Economic Impact of High Concentrations of Fecal Coliform
Creators: name: Sama, Preethi
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: Forty years after the passage of the Clean Water Act, 40% of the nation's waterways still do not meet water quality standards, In order to achieve the Clean Water Act's goals, the Environmental Protection Agency implemented the Total Maximum Daily Load (TMDL) program. A TMDL is a quantitative representation of pollution contribution from point and non point sources and is often used as part of watershed restoration plans. Watershed restoration plans involve implementing strategies and policies that can effectively achieve water quality standards; since TMDLs only provide information about the sources, they're use is limited. The addition of a health risk component identifies the costs from current contaminant levels, and the benefits from achieving compliance standards, thus allowing policy makers to choose the most efficient and cost effective restoration strategies. This research addresses the impact of high fecal coli from concentrations in Northeast Creek, identifying both an economic and health impact, associated with either the baseline (no policy) or establishment of a TMDL.

A Study of Particle Bounce in Internal Impaction-Based Samplers
Creators: name: Michaels, Linda D.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1984

description: Environmental and industrial hygiene samples of fine airborne particles are commonly collected in inertial impaction-based devices. In an ideal form these devices aerodynamically separate particles according to their size. It has been known for some time that solid particles with high Stokes numbers are capable of rebounding from impactor substrates and, consequently, distorting the particle size information obtainable from inertial impactors. However, the phenomenon of particle bounce is poorly understood, and little is known about how particle materials and substrates can affect the amount of particle bounce. In this experiment, a method was developed for the measurement of particle bounce from substrates of three different materials. The particle materials were also varied. The relative bounce of particles over a range of Stokes numbers was compared to literature reported results of similar experiments and to values predicted by a tentative theory of particle capture by surfaces. Experimental results showed good agreement with values expected on the basis of theory. Glass beads showed unexpectedly high collection efficiencies at small Stokes numbers when a dry substrate was used.

description: Why do wealthy democracies devote different amounts of resources to education, welfare, and punishment? Though each area has been addressed by large literatures on social policy, education and criminology, systematic interconnections among these domains emerge across advanced democracies. The different `elective affinities’ across contexts in patterns of spending do not just follow mechanically from crime rates and demographic structures, but a series of policy choices to simultaneously invest in – or withdraw from investing in – different areas. Understanding the link between these policy choices and voter demands is complex. In surveys, voters tend to support spending on all three areas – crime and punishment, education and welfare – giving little leverage at understanding tradeoffs. However, recent work on the demand for social policy suggests that survey instruments using traditional unconstrained choices among respondents fail to capture the types of tradeoffs that many voters are willing to make in the ballot box. With this project, we will conduct a survey in 2 countries – the UK and Sweden – to look at the micro-foundations of tradeoffs, specifically investigating preferences for devoting resources to investment in skills, protection of income security, and expanding resources for the police and prisons. A multi-country design will allow us to probe the question of whether emerging a) cleavage structure look similar across places and b) its politicization varies. The full Pre-Analysis Plan is also included as an attachment.

Total coliform and E.coli content of North Carolina new groundwater wells: an analysis of environmental variables and sampling practices among North Carolina counties for Spring 2009
Creators: name: Kelly, Mary Katherine
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: At the North Carolina state laboratory of public health (SLPH), approximately 34% of groundwater well samples were positive for total coliform bacteria. The main objective for this project is to explain these positive samples through the examination of the following potential variables. Data analysis with sample transport times and NC climatic regions found little or no effect of these variables on total coliforms and E. coli. Transport times were mostly observed in the 17-19 and 21-23 hours time ranges for the entire three-months with a little variation on a per month basis. Flushing times among survey participants fell mostly in the 0-5 minute time frame and most participants did not use coolants when transporting bacteriological samples. Data sources for this project included 2009 bacteriological well sample forms and a survey for all North Carolina county environmental health supervisors.

description: Harrow, Hassidim, and Lloyd showed that for a suitably specified $N \times N$ matrix $A$ and $N$-dimensional vector $\vec{b}$, there is a quantum algorithm that outputs a quantum state proportional to the solution of the linear system of equations $A\vec{x}=\vec{b}$. If $A$ is sparse and well-conditioned, their algorithm runs in time $\mathrm{poly}(\log N, 1/ε)$, where $ε$ is the desired precision in the output state. We improve this to an algorithm whose running time is polynomial in $\log(1/ε)$, exponentially improving the dependence on precision while keeping essentially the same dependence on other parameters. Our algorithm is based on a general technique for implementing any operator with a suitable Fourier or Chebyshev series representation. This allows us to bypass the quantum phase estimation algorithm, whose dependence on $ε$ is prohibitive.

description: We show that if $f$ is an annular homeomorphism admitting an attractor which is an irreducible annular continua with two different rotation numbers, then the entropy of $f$ is positive. Further, the entropy is shown to be associated to a $C^0$-robust rotational horseshoe. On the other hand, we construct examples of annular homeomorphisms with such attractors so that the rotation interval is uniformly large but the entropy approaches zero as much as desired. The developed techniques allow us to obtain similar results in the context of Birkhoff attractors.

description: There is increasing awareness of the need for pre- and post-doctoral professional development and career guidance, however many academic institutions are only beginning to build out these functional roles. As a graduate career educator, accessing vast silos and resources at a university and with industry-partners can be daunting, yet collaboration and network development are crucial to the success of any career and professional development office. To better inform and direct these efforts, forty-five stakeholders external and internal to academic institutions were identified and interviewed to gather perspectives on topics critical to career development offices. Using a stakeholder engagement visualization tool developed by the authors, strengths and weaknesses can be assessed. General themes from interviews with internal and external stakeholders are discussed to provide various stakeholder subgroup perspectives to help prepare for successful interactions. Benefits include increased engagement and opportunities to collaborate, and to build or expand graduate career development offices.
Emergence of the West Nile Virus in the United States: Veterinary and Human Public Health Implications
Creators: name: Montero, Julio C.

description: West Nile virus (WNV) (Flaviviridae), an arbovirus (arthropod-borne) isolated in the Western Hemisphere for the first time in New York in 1999, has become endemic in the United States, affecting wild birds, horses, humans and other mammals. Mortality rates associated with the North American variant of WNV among corvid birds (American crow), horses and humans in 2000 was 97%, 40%, and 10%, respectively. The current geographic distribution of WNV in North America includes 31 states, the District of Columbia, and the Canadian Province of Ontario. U.S. Public Health authorities estimate that WNV will continue to expand its range towards the west and eventually become a coast-to-coast arboviral pathogen. The goal of this study was to investigate vaccination as a means of controlling the spread of infection in equine hosts. In August 2001, the United States Department of Agriculture(USDA) conditionally approved a whole cell killed vaccine intended to protect horses from WNV infection. Thirty-five US Army-owned horses at Fort Bragg were inoculated with the WNV vaccine in the months of April and May 2002. Determination of antibody titers against WNV antigens was assessed using the Plaque Reduction Neutralization Test (PRNT). Results indicate that the WN virus vaccine is capable of stimulating the production of antibodies at 28 and 63 days after vaccination. Twenty five percent of the horses in the population sample (3 out of 12 animals) had detectable titers after the first immunization while 75% (9 of 12) had detectable antibody titers after the second administration of the vaccine.

description: The cytoskeleton protein α-fodrin plays a major role in maintaining structural stability of membranes. It was also identified as part of the brain γ-tubulin ring complex, the major microtubule nucleator. Here, we investigated the requirement of α-fodrin for microtubule spindle assembly during mitotic progression. We found that α-fodrin depletion results in abnormal mitosis with uncongressed chromosomes, leading to prolonged activation of the spindle assembly checkpoint and a severe mitotic delay. Further, α-fodrin repression led to the formation of shortened spindles with unstable kinetochore-microtubule attachments. We also found that the mitotic kinesin CENP-E had reduced levels at kinetochores to likely account for the chromosome misalignment defects in α-fodrin-depleted cells. Importantly, we showed these cells to exhibit reduced levels of detyrosinated α-tubulin, which primarily drives CENP-E localization. Since proper microtubule dynamics and chromosome alignment are required for completion of normal mitosis, this study reveals an unforeseen role of α-fodrin in regulating mitotic progression. Future studies on these lines of observations should reveal important mechanistic insight for fodrin’s involvement in cancer.
A modular description of $\mathscr{X}_0(n)$

description: As we explain, when a positive integer $n$ is not squarefree, even over $\mathbb{C}$ the moduli stack that parametrizes generalized elliptic curves equipped with an ample cyclic subgroup of order $n$ does not agree at the cusps with the $Γ_0(n)$-level modular stack $\mathscr{X}_0(n)$ defined by Deligne and Rapoport via normalization. Following a suggestion of Deligne, we present a refined moduli stack of ample cyclic subgroups of order $n$ that does recover $\mathscr{X}_0(n)$ over $\mathbb{Z}$ for all $n$. The resulting modular description enables us to extend the regularity theorem of Katz and Mazur: $\mathscr{X}_0(n)$ is also regular at the cusps. We also prove such regularity for $\mathscr{X}_1(n)$ and several other modular stacks, some of which have been treated by Conrad by a different method. For the proofs we introduce a tower of compactifications $\overline{Ell}_m$ of the stack $Ell$ that parametrizes elliptic curves---the ability to vary $m$ in the tower permits robust reductions of the analysis of Drinfeld level structures on generalized elliptic curves to elliptic curve cases via congruences.
