description: Early type galaxies have projected central density brightness profile logarithmic slopes, gamma^prime, ranging from about 0 to 1. We show that gamma^prime is strongly correlated, r= 0.83, with the coarse grain phase density of the galaxy core, Q_0 = rho/sigma^3. The gamma^prime-luminosity correlation is much weaker, r= -0.5. Q_0 also serves to separate the distribution of power-law profiles, gamma^prime>0.5 from nearly flat profiles, gamma^prime<0.3, although there are many galaxies of intermediate slope, at intermediate $Q_0$, in a volume limited sample. The transition phase density separating the two profile types is approximately 0.003, which is also where the relation between Q_0 and core mass shows a change in slope, the rotation rate of the central part of the galaxy increases, and the ratio of the black hole to core mass increases. These relations are considered relative to the globular cluster inspiral core buildup and binary black hole core scouring mechanisms for core creation and evolution. Globular cluster inspiral models have quantitative predictions that the data support, but no single model yet completely explains the correlations.

Chemical oceanography

description: The ocean is currently absorbing excess carbon from anthropogenic emissions, leading to reduced seawater-pH (termed ‘ocean acidification’). Instrumental records of ocean acidification are unavailable from well-ventilated areas of the deep ocean, necessitating proxy records to improve spatio-temporal understanding on the rate and magnitude of deep ocean acidification. Here we investigate boron, carbon, and oxygen isotopes on live-collected deep-sea bamboo corals (genus Keratoisis) from a pHtot range of 7.5–8.1. These analyses are used to explore the potential for using bamboo coral skeletons as archives of past deep-sea pH and to trace anthropogenic acidification in the subsurface North Atlantic Ocean (850–2000 m water depth). Boron isotope ratios of the most recently secreted calcite of bamboo coral skeletons are close to the calculated isotopic composition of borate anion in seawater (δ11Bborate) for North Atlantic corals, and 1–2‰ higher than δ11Bborate for Pacific corals. Within individual coral skeletons, carbon and oxygen isotopes correlate positively and linearly, a feature associated with vital effects during coral calcification. δ11B variability of 0.5–2‰ is observed within single specimens, which exceeds the expected anthropogenic trend in modern North Atlantic corals. δ11B values are generally elevated in Pacific corals relative to δ11Bborate, which may reflect pH-driven physiological processes aiding coral calcification in environments unfavorable for calcite precipitation. Elevated δ11B values are also observed proximal to the central axis in multiple Atlantic and Pacific specimens, relative to δ11Bborate, which might reflect ontogenetic variability in calcification rates. Although the observed boron isotope variability is too large to resolve the present anthropogenic ocean acidification signal at the studied depths in the North Atlantic (∼0.03–0.07 pH units), pH changes ⩾0.1 units might still be reconstructed using δ11B measurements in bamboo corals.

description: A gulf between constitutional and everyday perspectives is prevalent, and often overlain by gender divisions. To explore how this gulf can be bridged to allow for the inclusion of everyday concerns in constitutional discussion, we engaged with women in the Irish border area, a region where constitutional difference has striking effects in daily life. We held a series of small-scale deliberative cafés on cross-border health provision, which is linked to dysfunctions of regional governance and contentious constitutional issues. We asked if such open-ended deliberation allows everyday concerns to ‘scale out’ to wider territorial units and ‘scale up’ to the constitutional question. We found that the deliberative café, a radically inclusive method, facilitated a limited scaling up and out from everyday experience: participants collectively and credibly defined systemic dysfunctions on the regional level with policy implications for constitutional discussion. Although participants raised important political issues, they did not easily move from regional to constitutional discussion. We argue that this discursive disjuncture between regionalist policy and constitutional politics derives from a tension between wider regionalist state discourses (which determinedly avoid constitutional contention) and constitutional discourses (which lack a spatial dimension and assume one ‘ideal’ public rather than engage with many existing publics).

description: Resistive memories (RRAM) are promising candidates for replacing present nonvolatile memories and realizing storage class memories; hence resistance switching devices are of particular interest. These devices are typically memristive, with a large number of discrete resistance levels and in some configurations, they perform as analog memories. Noise studies have been used to enlighten further the resistance switching mechanism in these devices. Recently, a strong interest arose on the noise generated by RRAM/memristors because due to their inherent stochasticity can be used for cryptography and other security applications. In this work, two fully CMOS compatible memristive devices both with silicon nitride as switching material, were examined in terms of multi-level resistance operation. Using appropriate SET/RESET pulse sequences through a flexible analog tuning protocol, four stable resistance states were investigated through random telegraph noise measurements and analysis. A possible model enlightening the role of silicon nitride defects in the observed noise signals at different resistive states is presented.

description: We discuss the consequences of the approximate conservation of the vector and axial currents for the hadronic matrix elements appearing in beta decay if non-standard interactions are present. In particular the isovector (pseudo)scalar charge g_S(P) of the nucleon can be related to the difference (sum) of the nucleon masses in the absence of electromagnetic effects. Using recent determinations of these quantities from phenomenological and lattice QCD studies we obtain the accurate values g_S=1.02(11) and g_P=349(9) in the MS-bar scheme at mu=2 GeV. The consequences for searches of non-standard scalar interactions in nuclear beta decays are studied, finding epsilon_S=0.0012(24) at 90%CL, which is significantly more stringent than current LHC bounds and previous low-energy bounds using less precise g_S values. We argue that our results could be rapidly improved with updated computations and the direct calculation of certain ratios in lattice QCD. Finally we discuss the pion-pole enhancement of g_P, which makes beta decays much more sensitive to non-standard pseudoscalar interactions than previously thought.

description: Multimodal foundation models have significantly improved feature representation by integrating information from multiple modalities, making them highly suitable for a broader set of applications. However, the exploration of multimodal facial representation for understanding perception has been limited. Understanding and analyzing facial states, such as Action Units (AUs) and emotions, require a comprehensive and robust framework that bridges visual and linguistic modalities. In this paper, we present a comprehensive pipeline for multimodal facial state analysis. First, we compile a new Multimodal Face Dataset (MFA) by generating detailed multilevel language descriptions of face, incorporating Action Unit (AU) and emotion descriptions, by leveraging GPT-4o. Second, we introduce a novel Multilevel Multimodal Face Foundation model (MF^2) tailored for Action Unit (AU) and emotion recognition. Our model incorporates comprehensive visual feature modeling at both local and global levels of face image, enhancing its ability to represent detailed facial appearances. This design aligns visual representations with structured AU and emotion descriptions, ensuring effective cross-modal integration. Third, we develop a Decoupled Fine-Tuning Network (DFN) that efficiently adapts MF^2 across various tasks and datasets. This approach not only reduces computational overhead but also broadens the applicability of the foundation model to diverse scenarios. Experimentation show superior performance for AU and emotion detection tasks.

description: We study the transport properties, in particular, the thermoelectric figure of merit ZT of armchair graphene nanoribbons, AGNR-N (for N=4-12, with widths ranging from 3.7 to 13.6~Å) through strain engineering, where N is the number of carbon dimer lines across the AGNR width. We find that the tensile strain applied to AGNR-$N$ changes the transport properties by modifying the electronic structures and phonon dispersion relations. The tensile strain increases the ZT value of the AGNR-$N$ families with N=3p and N=3p+2, where $p$ is an integer. Our analysis based on accurate density-functional theory calculations suggests a possible route to increase the ZT values of AGNR-$N$ for potential thermoelectric applications.

description: The proposal we offer here (and in the more extensive 'white paper' proposal on which this article is based) tackles head-on the open access (OA) business models that have proven particularly problematic for implementation of OA in the humanities and social sciences (HSS). Our proposal suggests all tertiary institutions contribute to systemic support of the research process itself, including its entire scholarly output. A bold rethinking of the economics of OA by way of partnerships among scholarly societies and academic libraries funded by an institutional fee structure based on a student-and-faculty per-capita sliding scale, our plan is nevertheless intentionally incremental. Our proposal focuses first on HSS and primarily in the United States, but just as research and scholarship are increasingly global and collaborative, our plan is not bound by discipline or national borders, but can be adopted by all those looking for a more equitable and sustainable OA model.

Diarrhea in children

description: During the past three decades in Bangladesh, millions of tubewells have been installed to reduce the prevalence of diarrheal disease. This study evaluates the impacts of tubewell access and tubewell depth on childhood diarrhea in rural Bangladesh. A total of 59,796 cases of diarrhea in children under 5 were recorded in 142 villages of Matlab, Bangladesh during monthly community health surveys between 2000 and 2006. The location and depth of 12,018 tubewells were surveyed in 2002-04 and integrated with diarrhea and other data in a geographic information system. A proxy for tubewell access was developed by calculating the local density of tubewells around households. Logistic regression models were built to examine the relationship between childhood diarrhea, tubewell density and tubewell depth. Wealth, adult female education, flood control, population density and the child's age were considered as potential confounders. Baris (patrilineally-related clusters of households) with greater tubewell density were associated with significantly less diarrhea (OR (odds ratio) = 0.87, 95% confidence interval (CI): 0.85-0.89). Tubewell density had a greater influence on childhood diarrhea in areas that were not protected from flooding. Baris using intermediate depth tubewells (140-300 feet) were associated with more childhood diarrhea (OR = 1.24, 95% CI: 1.19-1.29) than those using shallow wells (10-140 feet). Baris using deep wells (300-990 feet) had less diarrheal disease than those using shallow wells, however, the difference was significant only when population density was low (< 1000 person/km2) or children were at the age of 13-24 months. Increased access to tubewells is associated with a lower risk of childhood diarrhea. Intermediate- depth wells are associated with more childhood diarrhea compared to shallower or deeper wells. These findings may have implications for on-going efforts to reduce exposure to elevated levels of arsenic contained in groundwater that is pumped in this study area primarily from shallow tubewells.

description: Navigation for blind persons represents a challenge for researchers in vision substitution. In this field, one of the used techniques to navigate is guidance. In this study, we develop a new approach for 3D trajectory following in which the requested task is to track a light path using computer input devices (keyboard and mouse) or a rigid body handled in front of a stereoscopic camera. The light path is visualized either on direct vision or by way of a electro-stimulation device, the Tongue Display Unit, a 12x12 matrix of electrodes. We improve our method by a series of experiments in which the effect of the modality of perception and that of the input device. Preliminary results indicated a close correlation between the stimulated and recorded trajectories.

description: We discuss to what extent the full set of Ward Identities constrain the four-point function of the stress-energy tensors or conserved currents in a conformal field theory. We calculate the number of kinematically unrestricted functional degrees of freedom governing the corresponding correlators and find that it matches the number of functional degrees of freedom governing scattering amplitudes of some "dual" massless particles in the auxiliary Minkowski space. We also formulate the conformal bootstrap constraints for the correlators in question in terms of only unrestricted degrees of freedom. As a by-product we find interesting parallels between solving Ward Identities in coordinate and momentum space.

description: In many areas of Bangladesh, it has been more than six years since a national campaign to test tubewells for arsenic (As) was conducted. Many households therefore draw their water for drinking and cooking from untested wells. A household drinking water survey of 6646 households was conducted in Singair upazilla of Bangladesh. A subset of 795 untested wells used by 1000 randomly selected households was tested in the field by trained village workers with the Hach EZ kit, using an extended reaction time of 40 min, and in the laboratory by high-resolution inductively-coupled plasma-mass spectrometry (HR ICP-MS). The household survey shows that more than 80% of the wells installed since the national testing campaign in this area were untested. Less than 13% of the households with untested wells knew where a low-As well was located near their home. Village workers using the Hach EZ kit underestimated the As content of only 4 out of 795 wells relative to the Bangladesh standard. However, the As content of 168 wells was overestimated relative to the same threshold. There is a growing need for testing tubewells in areas of Bangladesh where As concentrations in groundwater are elevated. This could be achieved by village workers trained to use a reliable field kit. Such an effort would result in a considerable drop in As exposure as it increases the opportunities for well switching by households.

description: The pulsar wind nebula CTB 87 (G74.9+1.2) is one of the sources emitting $γ$-rays with energies higher than 10 TeV, as measured by the Very Energetic Radiation Imaging Telescope Array System telescope (VERITAS). In this study, we undertake a reanalysis of the GeV emission from the CTB 87 region, utilising $\sim$16 years of high-energy $γ$-ray data collected with the Fermi Large Area Telescope. In the energy range of 0.03--1 TeV, the spectrum can be adequately described by a power-law model with an index of 1.34 $\pm$ 0.18, and the integral energy flux is calculated to be (7.25 $\pm$ 1.36) $\times$ 10$^{-13}$ erg cm$^{-2}$ s$^{-1}$. Based on the multiband data, we have employed a time-dependent model to investigate the non-thermal emission properties of CTB 87. In the model, it is assumed that particles with broken power-law energy distributions are continuously injected into the nebula. This results in multiband non-thermal emission being produced by relativistic leptons via synchrotron radiation and inverse Compton processes. Furthermore, the model suggests an energy of approximately 2.4 PeV for the most energetic particle in the nebula.

The result is a new complete and effective decision procedure for MITL. Although decision procedures for MITL already exist, the automata-based techniques they employ appear to be very difficult to realize in practice, and, to the best of our knowledge, no implementation currently exists for them. A prototype tool for MITL based on the encoding presented here has, instead, been implemented and is publicly available.

description: It is well known that the Sahel region of Africa is impacted by decadal scale variability in precipitation, driven by global sea surface temperatures. This work demonstrates that the National Center for Atmospheric Research’s Community Atmosphere Model, version 4 is capable of reproducing relationships between Sahelian precipitation variability and Indian and Atlantic Ocean sea surface temperature variations on such timescales. Further analysis then constructs a moisture budget breakdown using model output and shows that the change in precipitation minus evaporation in the region is dominated by column integrated moisture convergence due to the mean flow, with the convergence of mass in the atmospheric column mainly responsible. It is concluded that the oceanic forcing of atmospheric mass convergence and divergence to a first order explains the moisture balance patterns in the region. In particular, the anomalous circulation patterns, including net moisture divergence by the mean and transient flows combined with negative moisture advection, together explain the drying of the Sahel during the second half of the twentieth century. Diagnosis of moisture budget and circulation components within the main rainbelt and along the monsoon margins show that changes to the mass convergence are related to the magnitude of precipitation that falls in the region, while the advection of dry air is associated with the maximum latitudinal extent of precipitation.

description: In a recent paper (Beyer and Hennig, 2012 [9]), we have introduced a class of inhomogeneous cosmological models: the smooth Gowdy-symmetric generalized Taub-NUT solutions. Here we derive a three-parametric family of exact solutions within this class, which contains the two-parametric Taub solution as a special case. We also study properties of this solution. In particular, we show that for a special choice of the parameters, the spacetime contains a curvature singularity with directional behaviour that can be interpreted as a "true spike" in analogy to previously known Gowdy symmetric solutions with spatial T3-topology. For other parameter choices, the maximal globally hyperbolic region is singularity-free, but may contain "false spikes".

description: In September 2012, SERVIU, the regional arm of the Chilean Ministry of Hotusing and Urban Development (MINVU), tasked our program with evaluating and reassessing housing reconstruction efforts in Talca, the capital city of the Maule region, in the wake of the 2010 earthquake that affected the region. To carry out this task, we focused on a case study neighborhood in Talca’s historic center, Barrio Las Heras. This document provides the synthesis of fourteen weeks working on the project, including a presentation of the context, our assessment of the strengths and weaknesses of the reconstruction efforts to date, and recommendations for Talca’s future development.

description: The intertwining of magnetism with topology is known to give rise to exotic quantum phenomena. Here, we explore the magnetotransport properties of NdAlSi, a magnetic Weyl semimetal that spontaneously breaks inversion and time-reversal symmetries and hosts a large number of Weyl nodes. We observe a significant negative magnetoresistance, which we attribute to the chiral anomaly associated with multiple Weyl nodes. Remarkably, the extracted chiral coefficient reaches approximately $52~\mathrm{mΩ}^{-1}~\mathrm{m}^{-1}~\mathrm{T}^{-2}$, larger than many other topological materials. Additionally, we observe an exotic anomalous Hall effect with an out-of-sync behavior, where the anomalous Hall resistance does not exactly follow the field dependence of the magnetization, in contrast to that in conventional ferromagnets. These rich quantum transport phenomena, driven by the interplay between magnetism and Weyl nodes, establish NdAlSi as a prime platform for exploring the intricate topological behaviors of magnetic Weyl semimetals.

description: We report on optical photopolarimetric results of the radio-loud narrow line Seyfert 1 (RL-NLSy1) galaxy PMN J0948+0022 on 2012 December to 2013 February triggered by flux enhancements in near infrared and gamma-ray bands. Thanks to one-shot polarimetry of the HOWPol installed to the Kanata telescope, we have detected very rapid variability in the polarized-flux light curve on MJD 56281 (2012 December 20). The rise and decay times were about 140 sec and 180 sec, respectively. The polarization degree (PD) reached 36 +/- 3% at the peak of the short-duration pulse, while polarization angle (PA) remained almost constant. In addition, temporal profiles of the total flux and PD showed highly variable but well correlated behavior and discrete correlation function analysis revealed that no significant time lag of more than 10 min was present. The high PD and minute-scale variability in polarized flux provides a clear evidence of synchrotron radiation from a very compact emission region of 10^14 cm size with highly ordered magnetic field. Such micro variability of polarization are also observed in several blazar jets, but its complex relation between total flux and PD are explained by multi-zone model in several blazars. The implied single emission region in PMN J0948+0022 might be reflecting a difference of jets between RL-NLSy1s and blazars.

Subjects: Library science

description: Many thanks for a very fruitful trip to Columbia University’s Burke Library. Helpful staff enabled me to maximize my productivity during the short time I was there, and I came away thrilled with what I was able to accomplish. While in New York I went through a large amount of the materials in the National Christian Council of China papers, took photos of relevant items for future perusal, and obtained digital copies of much of the China Bulletin. The materials that I gathered and began looking through while at the Burke Library helped me get a feel for the origins of the “Christianize the Home” movement begun by the N.C.C. in the 1920s, which I plan to make central in my dissertation.

description: "Shelter in Paint: a portrait of an empty house" is an investigation into private space and private thought through the visual language of representational painting. Structured as though moving through the rooms of the house, this paper discusses different thematics of domestic space in response to a painting created throughout the course of this degree. It considers the entrance for the concept of interiority, the foundation as the history of interior art, vacant corners as spaces for daydreaming, domestic objects as portraits of the inhabitant, the neighbourhood in relation to public space, the kitchen as the domestic core, the bedroom for intimacy, and the attic for secrets and privacy. These parallels between psychological space and physical space attempt to answer research questions related to the emotional power of interior space, the rift between public and private life, and the ability of interior space to reveal to the inhabitant.
Towards an advanced water service level: Microbial drinking water quality management at government schools and healthcare facilities in resource-constrained rural settings, Kabarole Uganda

subject: Water resources engineering

description: Acquiring advanced water service levels as per the SDG6 remains a challenge, more so in Low- and Middle- Income settings; thus, this study seeks to improve drinking water quality management at schools and healthcare facilities through gaining knowledge on locally affordable solutions to keep drinking water safe in rural resource-constrained settings of Kabarole District in Uganda, Eastern Africa. A mixed methods approach helps to generate relevant data to answer research questions. Longitudinal monitoring water quality data for seventy-three institutions obtained between April 2022 – July 2023 from The Aquaya Institute with Conrad N. Hilton Foundation (CNHF) funding, and observations and Key Informant Interviews (KII) at 26 institutions formed the methods and data for this research. On analysis, 93.6% of the institutions used improved water points, but 8 in 10 tested positive for E. coli. Institutions rely mostly on piped water and rainwater collection. These sources experience seasonal water quality fluctuations. In both seasons, boreholes with handpumps had low-risk water. Water service levels fluctuated seasonally at schools, and 8 in 10 (n=26) water sources had a low sanitary risk. Cleaning and covering storage and drinking water containers emerged as the most prevalent drinking water quality practice. Water treatment topped the remedial actions suggested by the institutions. In conclusion, schools and healthcare facilities should maintain the hygiene of utensils and containers, invest in safe and reliable water sources like boreholes with hand pumps and pursue affordable treatment options to improve water quality.Please note that missing pages in the document are where signatures have been redacted.
Redactions from India in Modern Tibet

description: The library research award for my project, “Redactions from India in Modern Tibet,” allowed me to access the Tibetan collections at C.V. Starr library in July and August 2013 and further my research on Tibetan commentaries of Dignāga’s Ālambanaparīkṣā, a sixth-century Buddhist text composed in Sanskrit. One of the important commentaries I located on this text was a modern edition published in Lanzhou, P.R. of China, less than two years ago. I found this edition in the collected works of the author, Tendar Lharampa (1759-1831), which helped me to understand the text in a new light. Yet to my surprise, one of the most practical aspects of my research at C.V. Starr was when I was browsing the catalogues and the new Tibetan acquisitions that were not yet in the catalogue. At those times, I was able to locate several modern Tibetan publications that I had not heard about, thanks in no small part the instructive guidance of the Tibetan librarian, Dr. Lauren Hartley.

description: I used the Columbia University Libraries 2013 Research award to conduct research vital to my dissertation, which investigates the development of China’s first popular education programs during the late Qing and early Republican period (1898-1937), which a focus on how education reformers understood the relationship between literacy and citizenship. From July 28th through August 16th, I conducted archival research using materials at the Rare Book and Manuscript Library, the Burke Library at Union Theological Seminary, and using microfiche materials available through general circulation at Columbia. While at Columbia, my research focused primarily on the records of the International Institute of Rural Reconstruction (IIRR), and specifically the institutional records of the Chinese National Association of Mass Education Movements (MEM), co-founded by James Yen in 1923. These materials will form the evidentiary basis for my dissertation’s fifth chapter, entitled “Reevaluating Literacy: The Evolution of People’s Education and Local Experiments in the Rural Reconstruction Movement, 1926-1934.”
