We study the design of efficient approximation algorithms for the ℓ-center clustering and minimum-diameter ℓ-clustering problems in high-dimensional Euclidean and Hamming spaces. Our main tool is randomized dimension reduction. First, we present a general method of reducing the dependency of the running time of a hypothetical algorithm for the ℓ-center problem in a high-dimensional Euclidean space
The Quercetum Chorus Workshop introduced students in the Cal Poly Pomona Interdisciplinary Paris Study Abroad Program (CPP IPSAP) to methods of deepening human-tree relations through sound, drawing and movement. Students applied a multi-sensory approach to knowing trees by attuning to their frequencies, textures, shapes, and movements. They were invited to reimagine trees as more-than-human bodies
Jeffrey Breau of Harvard University and Natalie Bloch, Research Fellow at Lund University, discuss how psychedelic experiences are interpreted within religious traditions, with particular attention to Judaism and the emergence of new psychedelic churches in the United States.Their conversation explores how these experiences are shaped by cultural frameworks and by ongoing debates between perennial
Traumatic brain injury (TBI) is commonly associated with white matter injury, leading to persistent symptoms and long-term disability. While advanced age is linked to worse outcome post-TBI, the influence of sex remains highly controversial. The present study aimed to identify age- and sex-dependent differences in white matter pathology during the chronic phase of TBI using the central (midline) f
A blood group may be defined as an inherited character of the red cell surface detected by a specific alloantibody. This definition would not receive universal acceptance, since cell surface antigens on platelets and leucocytes might also be considered blood groups (see Chapter 4), as might acquired characteristics on red cells defined by autoantibodies or polyagglutinins. The definition is suitab
Spin crossover (SCO) complexes are highly promising candidates for a myriad of potential applications in room-temperature electronics; however, as it stands, establishing a clear connection between their spin-state switching and transport properties has been far from trivial. In this perspective, an effort to unravel the underlying charge transport mechanism in these SCO complexes, via a general t
Traumatic brain injury and stroke often result in contralateral sensorimotor deficits, including asymmetric posture. While these lateralized effects are classically attributed to neural tract disruption, recent evidence supports the existence of a complementary humoral pathway. Our previous work demonstrated that the neurohormone Arg-vasopressin (AVP) mediates right hindlimb responses to left-side
Studying the full universe of nearly 390,000 French patents filed between 1791 and 1900, I show that the nineteenth-century gender patenting gap arose less at the patent office than through unequal access to practical knowledge, collaborators, and time across the life course. I identify 4,165 women inventors using gender-specific honorifics, classify patents with machine learning, reconstruct the
PurposeThis study aims to assess the diffusion and integration of Circular Economy (CE) knowledge across academic disciplines, by examining how CE concepts spread within mainstream academic and disciplinary discourses.Design/Methodology/ApproachCE is conceptualized as a knowledge object, distinguishing between mainstream academic discourse (MAD) and mainstream disciplinary discourse (MDD). The res
Background: Adolescents are increasingly using classical psychedelics, yet little is known about how psychedelics use is related to their mental health. Emerging evidence suggests that adolescents may be more vulnerable to adverse outcomes in relation to psychedelic use compared to adults. This descriptive and exploratory study examined differences between adolescents and adults in reported psyche
The demand for safe and durable modified-wood products is increasing in the construction sector. In this work, the in situ wet-chemistry synthesis of a glassy MgO/Na2O–SiO2 solid in Scots pine (Pinus sylvestris L.) sapwood via a two-stage impregnation process using an industrial timber-impregnation autoclave is reported. Magnesium sulphate heptahydrate (MgSO4·7H2O), a historic fire retardant, and
Abstract INTRODUCTION Countries have varying, limited healthcare budgets for emerging disease-modifying therapies. Cost-effectiveness analysis, combined with country-level cost-effectiveness thresholds, can be used to estimate value-based prices (VBPs) for lecanemab and donanemab across 174 countries. METHODS The cost-effectiveness of lecanemab and donanemab was estimated using incremental cost an
Background Severe exacerbations (SevEx), the typical endpoint when evaluating asthma therapies, may provide incomplete assessment, as it relies on patient perception of disease and physician action. CompEx, a composite outcome that includes SevEx and acute worsening events (AWEs) (evaluated from e-diary entries using deterioration in peak expiratory flow (PEF), reliever medication use and worsenin
BACKGROUND: Early HIV diagnosis allows timely interventions to control HIV transmission. We have determined the proportion of recent infections among people living with HIV (PLHIV) enrolling to care in Ethiopia and identified factors associated with recent infection. METHODS: Participants (aged ≥ 15 years) newly enrolled in HIV care were recruited from urban clinics in central Ethiopia (2022-2024)
The purpose was to study the prognostic and predictive roles of DNA protein kinase catalytic subunit (DNA-PKcs), Ku70/80 and p53 for the effect of radiotherapy in breast cancer patients. Protein expressions of Ku70/80, DNA-PKcs and p53 were examined using immunohistochemistry in tumours from 224 breast cancer patients, who were randomised to receive post-operative radiotherapy or adjuvant chemothe
Purpose. Continuous minor steps of improvement in the management of breast cancer have resulted in decreased mortality rates during the last decades. The aim of this study was to compare the clinical outcome of patients with stage I breast cancer diagnosed during two time periods that differed with respect to adjuvant systemic therapy. Material and methods. The studied population consisted of all
