description: Combating poverty remains a major hindrance to economic development across Africa, even though it is well known that the poor are generally concentrated in rural areas. Paradoxically, identifying and targeting development efforts to the (very) poor remains a major challenge, mainly due to data deficiency and the wide application of popular but poorly adapted absolute poverty assessment approaches. This paper succinctly revisits the comparative advantages of relative over absolute poverty measures, and their prospects for application in rural Africa. Claims in favour of the relative approach are then substantiated by its application to empirically elicit poverty distribution among households in rural Cameroon. Analytical results fundamentally based on principle component analysis strengthen our advocacy for a dominant application and better prospects for relative poverty assessments over absolute ones, especially in rural areas of developing countries such as Cameroon, where data unavailability persists. In addition, the holistic and multi-dimensional attributes embedded in the relative approach oblige an atonement of its overarching prospects for identifying and targeting the poor in order to fight poverty and enhance economic development, especially in rural areas in Africa, as demonstrated in the Cameroonian case study.

description: Digital scientific data created during the last few decades offer potential for analysis by future users and for integration with other data from different disciplines to support interdisciplinary analysis, discovery, decision-making, and education. However, significant barriers remain in managing and documenting such data sufficiently to meet the needs of future and interdisciplinary users. One possible approach to overcoming these barriers is to develop and implement digital repository systems within an appropriate institutional context. We report here on progress in implementing a digital repository using the Fedora open source software, working with the Columbia University Libraries. After discussing platform selection, feasibility testing, and collection development policy issues, we describe our experience with data migration and parallel ingest of data. We then discuss current system enhancements, challenges, and plans to improve capabilities for ingesting data and for enabling dissemination that supports future applications and use.
In operando active learning of interatomic interaction during large-scale simulations

description: A well-known drawback of state-of-the-art machine-learning interatomic potentials is their poor ability to extrapolate beyond the training domain. For small-scale problems with tens to hundreds of atoms this can be solved by using active learning which is able to select atomic configurations on which a potential attempts extrapolation and add them to the ab initio-computed training set. In this sense an active learning algorithm can be viewed as an on-the-fly interpolation of an ab initio model. For large-scale problems, possibly involving tens of thousands of atoms, this is not feasible because one cannot afford even a single density functional theory computation with such a large number of atoms. This work marks a new milestone toward fully automatic ab initio-accurate large-scale atomistic simulations. We develop an active learning algorithm that identifies local subregions of the simulation region where the potential extrapolates. Then the algorithm constructs periodic configurations out of these local, non-periodic subregions, sufficiently small to be computable with plane-wave density functional theory codes, in order to obtain accurate ab initio energies. We benchmark our algorithm on the problem of the screw dislocation motion in bcc tungsten and show that our algorithm reaches ab initio accuracy, down to typical magnitudes of numerical noise in DFT codes. We show that our algorithm reproduces material properties such as core structure, Peierls barrier, and Peierls stress. This unleashes new capabilities for computational materials science toward applications which have currently been out of scope if approached solely by ab initio methods.

Nuclear Spin Dynamics in Parabolic Quantum Wells

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: We present a detailed analytical and numerical analysis of the nuclear spin dynamics in parabolic quantum wells. The shallow potential of parabolic quantum wells permits substantial modification of the electronic wave function in small electric fields. The nuclear spin relaxation via the hyperfine interaction depends on the electronic local density of states, therefore the local nuclear relaxation time depends sensitively on the electric field. For an inhomogeneous nuclear magnetization, such as generated by dynamic nuclear polarization, the total nuclear magnetization dynamics can similarly be altered. We examine this effect quantitatively and the effect of temperature, field, well thickness, and nuclear spin diffusion.

description: Machine learning algorithms are effective in several applications, but they are not as much successful when applied to intrusion detection in cyber security. Due to the high sensitivity to their training data, cyber detectors based on machine learning are vulnerable to targeted adversarial attacks that involve the perturbation of initial samples. Existing defenses assume unrealistic scenarios; their results are underwhelming in non-adversarial settings; or they can be applied only to machine learning algorithms that perform poorly for cyber security. We present an original methodology for countering adversarial perturbations targeting intrusion detection systems based on random forests. As a practical application, we integrate the proposed defense method in a cyber detector analyzing network traffic. The experimental results on millions of labelled network flows show that the new detector has a twofold value: it outperforms state-of-the-art detectors that are subject to adversarial attacks; it exhibits robust results both in adversarial and non-adversarial scenarios.

description: The hydrazones of nonsteroidal anti-inflammatory drugs (NSAIDs) diclofenac and ibuprofen are synthesized with aldehydes of pyridine and imidazole and are characterized by 1H, 13C and mass spectroscopy. Cu(II) complexes of hydrazones constructed from these ligands possess square planar geometry for bidentate diclofenac-hydrazone and tridentate ibuprofen-hydrazone conjugates with [Cu(L)2] and [Cu(L)Cl] compositions, respectively. The observed irreversible Cu(II)/Cu(I) redox couple in the range of +0.20 to +0.61 V is due to the substantial distortion in the square-planar geometry. ESR studies indicate the appreciably covalent character within M–L bonding due to extensive delocalization of electron from dx2–-y2 orbital. The hydrazone–NSAID conjugates exhibit substantial cytotoxicity against A-549, HCT-116 and MDA-MB-231 cancer cell lines with ibuprofen-imidazole-hydrazone ligand possessing the lowest IC50 (2.26 µM) amongst the synthesized NSAID-conjugates. Interestingly, its Cu(II) complex also displays excellent anticancer activity against MDA-MB- 231 with IC50 value of 3.58 µM. Such a feature may be ascribed to the synergistic association of Cu(II)–NSAID–hydrazone linkage. Thus, conjugation of NSAID with hydrazone and its complexation with a bioactive metal ion may be regarded as a potential strategy for designing of non-platinum anticancer agents.

description: Accurate medical symptom coding from unstructured clinical text, such as vaccine safety reports, is a critical task with applications in pharmacovigilance and safety monitoring. Symptom coding, as tailored in this study, involves identifying and linking nuanced symptom mentions to standardized vocabularies like MedDRA, differentiating it from broader medical coding tasks. Traditional approaches to this task, which treat symptom extraction and linking as independent workflows, often fail to handle the variability and complexity of clinical narratives, especially for rare cases. Recent advancements in Large Language Models (LLMs) offer new opportunities but face challenges in achieving consistent performance. To address these issues, we propose Task as Context (TACO) Prompting, a novel framework that unifies extraction and linking tasks by embedding task-specific context into LLM prompts. Our study also introduces SYMPCODER, a human-annotated dataset derived from Vaccine Adverse Event Reporting System (VAERS) reports, and a two-stage evaluation framework to comprehensively assess both symptom linking and mention fidelity. Our comprehensive evaluation of multiple LLMs, including Llama2-chat, Jackalope-7b, GPT-3.5 Turbo, GPT-4 Turbo, and GPT-4o, demonstrates TACO's effectiveness in improving flexibility and accuracy for tailored tasks like symptom coding, paving the way for more specific coding tasks and advancing clinical text processing methodologies.

The search is done on LIGO O2 data using the Falcon analysis pipeline. The results presented here double the sensitivity over any other result on the same data. The search is capable of detecting low ellipticity sources up to 170 pc. We establish strict upper limits which hold for worst-case signal parameters. We list outliers uncovered by the search, including several which we cannot associate with any known instrumental cause.

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The upper bound on the value of the surface gravity, g_s, for neutron stars with equations of state respecting v_sound <= c, is derived. This bound is inversely proportional to the maximum allowable mass M_max, and it reads g_s <= 1.411 x 10^15 (M_sun/M_max) cm/s^2. It implies an absolute upper bound 7.4 x 10^14 cm/s^2 if one uses the 2sigma lower bound on the neutron mass measured recently in 4U1700-37, 1.9 M_sun. A correlation between g_s and the compactness parameter 2GM/Rc^2 for baryonic stars is analyzed. The properties of g_s of strange quark stars and its upper bounds are discussed using the scaling properties of the strange-star models.

description: We point out that the recent data from the Sudbury Neutrino Observatory, together with other relevant measurements from solar and reactor neutrino experiments, convincingly show that the flavor transitions of solar neutrinos are affected by Mikheyev-Smirnov-Wolfenstein (MSW) effects. More precisely, one can safely reject the null hypothesis of no MSW interaction energy in matter, despite the fact that the interaction amplitude (formally treated as a free parameter) is still weakly constrained by the current phenomenology. Such a constraint can be improved, however, by future data from the KamLAND experiment. In the standard MSW case, we also perform an updated analysis of two-family active oscillations of solar and reactor neutrinos.

Localized Streetscapes : A context based approach to managing stormwater on steep slopes
Creators: name: Fairburn, Bryce
Publisher: name: The University of British Columbia
Year: 2021

description: Localized streetscapes explores how water infrastructure affects the ways in which people relate to, and engage with, the spaces they inhibit. Following a historical exploration that reveals the sundry nature of water infrastructure, this thesis then seeks to explain the influence of high-modernism on 21st century infrastructural systems. This broad inquiry is followed by an examination of urbanization and climate change and the resulting impetus for a new approach to the design of cities. These concepts are applied to the local context, Vancouver, in an effort to aid the City in reaching its Rain City Strategy targets. This design explores the feasibility of managing and retaining stormwater on steep streetscapes. A pedestrian focused approach is taken that emphasizes accessibility and deprioritized vehicular convenience. The design project takes the form of an interconnected streetscape that is both scalable and reproducible.

description: Hilda asteroids orbit at the outer edge, or just outside of the Main Belt, occupying the 2:3 mean motion resonance with Jupiter. It is known that the group shows a mixed taxonomy that suggests the mixed origin of Hilda members, having migrated to the current orbit both from the outer Main Belt and from the Trojans swarms. But there are still few observations for comparative studies that help in understanding the Hilda group in deeper details. We identified 125 individual light curves of Hilda asteroids observed by the K2 mission. We found that despite of the mixed taxonomies, the Hilda group highly resembles to the Trojans in the distribution of rotation periods and amplitudes, and even the LR group (mostly C and X-type) Hildas follow this rule. Contrary to the Main Belt, Hilda group lacks the very fast rotators. The ratio of extremely slow rotators (P>100 h) is a surprising 18%, which is unique in the Solar System. The occurrence rate of asteroids with multiple periods (4%) and asteroids with three maxima in the light curves (5%) can be signs of high rate of binarity, which we can estimate as 25% within the Hilda group.

Year: 2008

description: This paper investigates the potential for archiving primary source documents and the datasets created from these documents in the institutional repository DSpace. Through an initiative at the University of Rochester (U.R.), the Friends of the U.R. Libraries awarded a dissertation grant in support of depositing a unique dataset into the University's digital archive. This grant funded the acquisition and digitization of WWII military documents currently located at the Bundesarchiv in Berlin, Germany. On condition of awarding these funds, the doctoral student agreed to deposit both the digitized primary documents and the unique dataset created from these documents into DSpace. This approach has the potential to increase the awareness and use of DSpace, while also capitalizing on the contribution that doctoral students might bring to data depositories. The paper also discusses the use of DSpace technology as a data depository and considers current and future enhancements to DSpace. Issues such as metadata, the availability of funds, interface functionality, and copyright are important considerations for expanding this initiative.
Non-integrability of the $Ω$-deformation

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We study integrability on the supergravity vacuum dual to the field theoretical $Ω$-deformation of $\mathcal{N}=4$ super Yang-Mills theory. The deformation manifests itself as turning on a Kalb-Ramond field on the (Euclidean) AdS$_5\times$S$^5$, while the associated $H_3$ flux ignores half of the geometric isometries. By constructing appropriate string embeddings that incorporate the essential $H_3$ flux contribution on this background, we study their fluctuations through the associated Hamiltonian systems. Each and every case demonstrates that the string exhibits non-integrable dynamics, which in turn suggests that the $Ω$-deformation does not preserve classical integrability.

description: Compared to replication-based storage systems, erasure-coded storage incurs significantly higher overhead during data updates. To address this issue, various parity logging methods have been pro- posed. Nevertheless, due to the long update path and substantial amount of random I/O involved in erasure code update processes, the resulting long latency and low throughput often fail to meet the requirements of high performance applications. To this end, we propose a two-stage data update method called TSUE. TSUE divides the update process into a synchronous stage that records updates in a data log, and an asynchronous stage that recycles the log in real-time. TSUE effectively reduces update latency by transforming random I/O into sequential I/O, and it significantly reduces recycle overhead by utilizing a three-layer log and the spatio-temporal locality of access patterns. In SSDs cluster, TSUE significantly im- proves update performance, achieving improvements of 7.6X under Ali-Cloud trace, 5X under Ten-Cloud trace, while it also extends the SSD's lifespan by up to 13X through reducing the frequencies of reads/writes and of erase operations.

description: This paper investigates the role of information and search cost in the price formation in thin farmland markets. Using a comprehensive data set with more than 10,000 transactions between 2014–2017 in one of the eastern German Federal States, we estimate a two-tier model to capture deviations from the efficient price due to search costs asymmetrically distributed between buyers and sellers. Relating these costs to the degree of professionalism, we find institutional sellers relying on public tenders to achieve the lowest losses from being information deficient. No differences can be related to farmer compared to non-farmer buyers.

description: While the exponential growth of web based data sources has expanded access to the research community, this same growth has presented a series of challenges to Data Libraries that attempt to promote a mixture of online data resources alongside library licensed resources. Even with advanced content management systems, many Data Libraries devote a great deal of effort describing similar sets of web based data resources for local patrons. The Metadata Share Project attempts to reduce the effort required to document the growing number of web based data sources by sharing DDI compliant data descriptions across research libraries. This paper describes a test initiative by Duke University's Data GIS Services and Emory University's Electronic Data Center to share library DDI resources in order to expand resources at both institutions while reducing the burden of documenting data resources in DDI. We hope to expand the discussion of sharing DDI resources across data libraries by discussing our experience.

description: The amount of sensitive data, which is transmitted wirelessly will increase with future technologies. This raises many questions about secure data transmission. Besides cryptography, information-theoretic security gained increasing attention over the recent years. Among others, it deals with the problem of secure data transmission on the physical layer to a legitimate receiver (Bob) in the presence of an eavesdropper (Eve). In this work, we investigate upper and lower bounds on the secrecy outage probability for slowly-fading wiretap channels with an arbitrary dependency structure between the fading channels to Bob and Eve. Both cases of absence of channel-state information at the transmitter (CSI-T) and availability of CSI-T of only the main channel to the legitimate receiver are considered. Furthermore, we derive explicit expressions for the upper and lower bounds for Rayleigh fading and compare them to the case of independent channels. The joint distribution of the legitimate and eavesdropper channels has a tremendous impact on the achievable secrecy outage probability. The bounds enable developing guaranteed secrecy schemes by only measuring the marginal channel distributions.

description: A jelenleg Magyarországon működő mintegy 500 pálinkabérfőző vállalkozás döntő többsége a hagyományos kisüsti lepárlási módot alkalmazza. Ezen üzemek sajátosságait figyelembe véve olyan modellt alakítottunk ki, amelyen szimulációs vizsgálatok elvégzésére nyílt lehetőség az @Risk programcsomag segítségével. Megállapítást nyert, hogy alacsonynak tekinthető, 550 Ft/liter bérfőzési díj mellett a vállalkozások számára a nyereség elérésére 61% esély mutatkozik. A bérfőzés átlagos önköltsége majdnem megegyezik ezzel az összeggel, így indokolttá vált az önköltség csökkentésének lehetőségeit megvizsgálni. Az önköltségre legnagyobb növelő hatást a fajlagos bérköltség jelenti, az energia és az általános költségek változásának hatása csupán hatoda-tizede a bérköltségnek. A kibocsátás növelésével csökkenthető lenne az önköltség, azonban a bérfőzés mint szolgáltatás esetén ez csak növekvő fogyasztói igény esetén valósulhat meg. Javasolható a pálinkakészítés nem főállásként, hanem kiegészítő jövedelemszerzési tevékenységként történő folytatása. Összességében a bérfőzés jövedelemtermelőnek tekinthető, de a vállalkozások erőforrás-ellátottsága, helye, kitettsége nagymértékben befolyásolja ezt a jövedelemtermelő képességet. ------------ The majority of the nearly 500 ”pálinka” distillery companies currently operating in Hungary use the traditional “kisüsti” distilling method. Considering the peculiarities of these plants, we developed a calculation model that could be used to simulate the @Risk program package. It was found that 61% have a chance of income because of a low service charge rate of 550 HUF/litre pálinka. The average cost per litre is almost equal to this amount, and it is therefore justified to examine the possibilities of reducing the cost of distilling. The most significant increase in cost is the specific wage cost, and the effect of changes in energy and overheads costs is only six-tenths of the wage cost. By increasing the output, it would be possible to reduce the unit cost, but this can only be achieved by increasing consumer demand. It is advisable to continue making pálinka as a part-time job. Generally, the pálinka making can be considered as a profit generator, but the resources, location, and demand have a great influence on this income-generating capacity.
Impurity Effects on the A_1-A_2 Splitting of Superfluid 3He in Aerogel

description: When liquid 3He is impregnated into silica aerogel a solid-like layer of 3He atoms coats the silica structure. The surface 3He is in fast exchange with the liquid on NMR timescales. The exchange coupling of liquid 3He quasiparticles with the localized 3He spins modifies the scattering of 3He quasiparticles by the aerogel structure. In a magnetic field the polarization of the solid spins gives rise to a splitting of the scattering cross-section of for `up' vs. `down' spin quasiparticles, relative to the polarization of the solid 3He. We discuss this effect, as well as the effects of non-magnetic scattering, in the context of a possible splitting of the superfluid transition for $\uparrow\uparrow$ vs. $\downarrow\downarrow$ Cooper pairs for superfluid 3He in aerogel, analogous to the A_1-A_2 splitting in bulk 3He. Comparison with the existing measurements of T_c for B< 5 kG, which show no evidence of an A_1-A_2 splitting, suggests a liquid-solid exchange coupling of order J = 0.1 mK. Measurements at higher fields, B > 20 kG, should saturate the polarization of the solid 3He and reveal the A_1-A_2 splitting.

description: Identifying and characterising reionised bubbles enables us to track both their size distribution, which depends on the primary ionising sources, and the relationship between reionisation and galaxy evolution. We demonstrate that spectrally resolved $z\gtrsim6$ Lyman-alpha (Ly$α$) emission can constrain properties of reionised regions. Specifically, the distant from a source to a neutral region sets the minimum observable Ly$α$ velocity offset from systemic. Detection of flux on the blue side of the Ly$α$ resonance implies the source resides in a large, sufficiently ionised region that photons can escape without significant resonant absorption, and thus constrains both the sizes of and the residual neutral fractions within ionised bubbles. We estimate the extent of the region around galaxies which is optically thin to blue Ly$α$ photons, analogous to quasar proximity zones, as a function of the source's ionising photon output and surrounding gas density. This optically thin region is typically $\lesssim 0.3$ pMpc in radius (allowing transmission of flux $\gtrsim -250$ km s$^{-1}$), $\lesssim 20$% of the distance to the neutral region. In a proof-of-concept, we demonstrate the $z\approx6.6$ galaxy COLA1 -- with a blue Ly$α$ peak -- likely resides in an ionised region $>0.7$ pMpc, with residual neutral fraction $<10^{-5.5}$. To ionise its own proximity zone we infer COLA1 has a high ionising photon escape fraction ($f_{\mathrm{esc}}>0.50$), relatively steep UV slope ($β< -1.79$), and low line-of-sight gas density ($\sim0.5\times$ the cosmic mean), suggesting it is a rare, underdense line-of-sight.

Tomorrow - Ensuring Sustainable Data and Metadata for the Future
Creators: name: Vardigan, Mary
Publisher: name: Zenodo
Year: 2008

description: How do we ensure that the digital assets we create, enhance, and disseminate are preserved for future generations and remain usable for research, despite rapid-paced technological change? How do we protect the investment we make in data resources over the full life course of a project and not lose information along the way? These are questions that the social science data archives and others concerned with the development of cyberinfrastructure need to answer as we look to tomorrow. This presentation will focus on the big picture in terms of recent developments in the field of digital preservation and then will narrow in scope to discuss the role of DDI in a sustainable digital preservation program; the use of DDI at ICPSR and in a new project that covers the data life cycle; and finally some challenges remaining that we collectively need to solve.
Yesterday, Today and Tomorrow - The Vision
Creators: name: Wanschneider, Bo
Publisher: name: Zenodo

description: If any of you have ever read the popular book by Nicholas Carr titled, "Does IT Matter", you know that he is being intentionally provocative in challenging us to redefine how we invest in Information Technology. In his book he talks about proprietary and infrastructural technology, and lumps most IT into latter. The premise is that the true value of IT is not fully realized until it is broadly shared, homogenized and standardized. In essence, we lose our ability, or need, to differentiate ourselves and we are at a point where innovation on an individual/institutional level will not lead to a meaningful advantage. That does not preclude this innovation, it simply states that the true value lies in sharing the innovation. Although his book is geared towards the private sector, there are many parallels to the world of Higher Education and certainly the financial realities are prominent. Faced with inevitable budget constraints, the maturation of DDI, and advances in other technologies the need to articulate a shared vision and act collectively becomes imperative. In this part of the panel we will talk about commoditization of IT and how we painted a vision for shared development, resources and access with the ODESI project.
Electronic states and magnetic excitations in LiV2O4: Exact diagonalization study

description: Motivated by recent inelastic neutron scattering experiment we examine magnetic properties of LiV2O4. We consider a model which describes the half-filled localized A1g spins interacting via frustrated antiferromagnetic Heisenberg exchange and coupled by local Hund's interaction with the 1/8-filled itinerant Eg band, and study it within an exact diagonalization scheme. In the present study we limited the analysis to the case of the cluster of two isolated tetrahedrons. We obtained that both the ground state structure and low-lying excitations depend strongly on the value of the Hund's coupling which favors the triplet states. With increasing temperature the triplet states become more and more populated which results in the formation of non-zero residual magnetic moment. We present the temperature dependence of calculated magnetic moment and of the spin-spin correlation functions at different values of Hund's coupling and compare them with the experimental results.

The roles of adhesion, internal heat generation and elevated temperatures in normally loaded, sliding rough surfaces

description: The thermal effects of plastic and frictional heat generation and elevated temperature were examined along with the role of adhesion in the context of galling wear, using a representative crystal plasticity, normally loaded, sliding surface model. Galling frequency behaviour was predicted for 316L steel. Deformation of the surfaces was dominated by the surface geometry, with no significant effect due to variations in frictional models. Plastic and frictional heating were found to have a minimal effect on the deformation of the surface, with the rapid conduction of heat preventing any highly localised heating. There was no corresponding effect on the predicted galling frequency response. Isothermal, elevated temperature conditions caused a decrease in galling resistance, driven by the temperature sensitivity of the critical resolved shear stress. The extent of deformation, as quantified by the area of plastically deformed material and plastic reach, increased with temperature. Comparisons were made with literature results for several surface amplitude and wavelength conditions. Model results compared favourably with those in the literature. However, the reduction in predicted galling resistance with elevated temperature for a fixed surface was not as severe as observations in the literature, suggesting other mechanisms (e.g. phase transformations, surface coatings and oxides) are likely important.

description: Thin polypropylene (CH$_2$) fibers have been used for internal experiments in storage rings as an option for hydrogen targets. The change of the hydrogen content due to the radiation dose applied by the circulating proton beam has been investigated in the range $1\cdot10^6$ to $2\cdot10^8$~Gy at beam momenta of 1.5 to 3 GeV/c by comparing the elastic pp-scattering yield to that from inelastic p-carbon reactions. It is found that the loss of hydrogen as a function of applied dose receives contributions from a fast and a slow component.

description: de Haas-van Alphen oscillation spectrum is studied for an idealized two-dimensional Fermi liquid with two parabolic bands in the case of canonical (fixed number of quasiparticles) and grand canonical (fixed chemical potential) ensembles. As already reported in the literature, oscillations of the chemical potential in magnetic field yield frequency combinations that are forbidden in the framework of the semiclassical theory. Exact analytical calculation of the Fourier components is derived at zero temperature and an asymptotic expansion is given for the high temperature and low magnetic field range. A good agreement is obtained between analytical formulae and numerical computations.
