Published: April 2024

Abstract
Sensory perceptions are a novel point of departure for lighting research, where human factors have long been approached through isolated variables and controlled environments. However, informed by philosophy and social sciences and supported by ethnographical methods, researchers and practitioners are gaining new ground in understanding human-environment relations by approaching user perspectives in empirical inquiries. Situating the lighting in spatial settings and sensory experiences is crucial when exploring the dynamics of the changing visual perception of aging and vision loss, and how these phenomena can affect everyday life. Although spatial and sensory perceptions have typically been approached from different positions represented by architects or anthropologists, the following question remains: How can we develop a methodological framework for exploring entwined sensory and spatial experiences? This paper presents the method development process for our upcoming sensory and spatial fieldwork in the project “The role of light when vision changes.” The process is described in autoethnographic narratives, analysis of the technological frames, approaches, and understandings of light represented in the project, and the knowledge gained from testing the developed tools and schemes hands-on in a home environment. The initial findings indicate that both spatial and sensory experiences are interactional, as experiences situated in a specific body interacting with the specific environment it is situated in. Furthermore, in addition to the changes in visual perception, the spatial and luminous characteristics of the indoor and outdoor environments are also dynamic and changing, making the aspects of transitions and thresholds relevant for our upcoming fieldwork. Our hypothesis is that the shared technological frame developed in the project includes the relevant qualitative and quantitative measures that will allow us to make the knowledge of visually impaired participants explicit in ways that will inform and improve future lighting design.
Optical momentum distributions in monochromatic, isotropic random vector fields
Authors: Gadeyne Titouan , Dennis Mark R 
Published: April 2024

Abstract
We investigate the decomposition of the electromagnetic Poynting momentum density in three-dimensional random monochromatic fields into orbital and spin parts, using analytical and numerical methods. In sharp contrast with the paraxial case, the orbital and spin momenta in isotropic random fields are found to be identically distributed in magnitude, increasing the discrepancy between the Poynting and orbital pictures of energy flow. Spatial correlation functions reveal differences in the generic organization of the optical momenta in complex natural light fields, with the orbital current typically forming broad channels of unidirectional flow, and the spin current manifesting larger vorticity and changing direction over subwavelength distances. These results are extended to random fields with pure helicity, in relation to the inclusion of electric-magnetic democracy in the definition of optical momenta.

Abstract
Transition metal dichalcogenides (TMDs) have emerged as attractive two-dimensional semiconductors for future electronic and optoelectronic applications. Their charge transport properties, such as conductivity and the type of charge carriers, can be effectively controlled by substitutional doping of the transition metal atoms. However, the effects of doping on the excitonic properties, particularly their dynamical properties, have been less studied. Using Nb-doped MoSe2 as a case study, we experimentally investigate the effect of doping on excitonic dynamics in TMDs. Transient absorption measurements are used to directly compare the dynamical properties of excitons in Nb-doped MoSe2 across monolayer, bilayer, and bulk flakes with their undoped counterparts. The exciton lifetimes in Nb-doped flakes are significantly shorter than those in their undoped counterparts. This effect is attributed to the trapping of excitons in defect states introduced by Nb impurities. These results reveal an important consequence of Nb doping on excitonic dynamics in TMDs.

Abstract
Hybrid structures consisting of two-dimensional (2D) magnets and semiconductors have exhibited extensive functionalities in spintronics and opto-spintronics. In this work, we have fabricated WSe2/Fe3GeTe2 van der Waals heterostructures and investigated proximity effects on 2D magnetism. Through reflective magnetic circular dichroism, we have observed a temperature-dependent modulation of magnetic order in the heterostructure. For temperatures above

40

K

, WSe2-covered Fe3GeTe2 exhibits a larger coercive field than that observed in bare Fe3GeTe2, accompanied by a noticeable enhancement of the Curie temperature by

21

K

. This strengthening suggests an increase in magnetic anisotropy in the interfacial Fe3GeTe2 layer, which can be attributed to the spin–orbit coupling (SOC) proximity effect induced by the adjacent WSe2 layers. However, at much lower temperatures (

T
<
20

K

), a non-monotonic modification of the coercive field is observed, showing both reduction and enhancement, which depends on the thickness of the WSe2 and Fe3GeTe2 layers. Moreover, an unconventional two-step magnetization process emerges in the heterostructure, indicating the short-range nature of SOC proximity effects. Our findings on proximity coupling may shed light on the design of future spintronic and memory devices based on 2D magnetic heterostructures.

Published: April 2024

Abstract
A facile sol–gel approach was utilized to synthesis BiFe1-xTixO3 multiferroic ferrites, denoted as BFO-xTi (with x from 0.00 to 0.10). XRD analysis revealed that the undoped BFO ferrite exhibited a rhombohedral structure, and a transition from the rhombohedral phase to the pseudo-cubic phase occurred as the Ti content increased. The optical band gap increased from 2.00 eV to 2.23 eV with a Ti substitution at 0.10 mol. The magnetic properties exhibited a transition from antiferromagnetic to ferromagnetic phase due to the structural phase transition and super-exchange interaction between the 3d orbitals of Ti4+ and Fe3+/Fe2+ at the B-sites through oxygen vacacies. The sample with a 0.10 mol Ti substitution demonstrated the highest M
s and M
r values of 3.68 emu g−1 and 7.21 × 10–3 emu g−1, respectively. Overall, the results suggest that the BiFe1-xTixO3 multiferroic ferrites with optimal composition hold promise for use in magneto-optical devices.

Abstract
Alumina/carbon composites are modern nanomaterials used as adsorbents, catalysts, catalyst supports, supercapacitors, and electrode materials for fuel cells. Among other methods, aluminum anodizing is fairly fast and inexpensive for producing anodic alumina/carbon composites with controllable properties. In the present study, the morphology and composition of carbon-enriched anodic alumina films were obtained during aluminum anodic oxidation in formic acid with ammonium heptamolybdate (C content is ca. 5.0 mass%) or oxalic acid (C content 3.4 mass%) additives. The anodic alumina films have a wide blue fluorescence (FL) in the 400–650 nm wavelength range with a maximum at ca. 490 nm. The FL decay is nonexponential and has an average lifetime of 1.54 and 1.59 ns for ammonium heptamolybdate and oxalic acid additives, respectively. As samples obtained in sulfuric acid (i.e. without carbon) do not possess detectable FL in the 400–650 nm wavelength range, it was concluded that carbon-containing inclusions are responsible for the FL properties of the films. The initial samples were dissolved in the hot aqueous HCl solution and then dialyzed to extract the carbon-containing component. It was shown that the solutions contain nanoparticles of amorphous carbon with a 20–25 nm diameter. Carbon nanoparticles also exhibit an excitation-dependent emission behavior at 280–450 nm excitation wavelengths with average lifetimes of 7.25–8.04 ns, depending on the composition of the initial film. Carbon nanoparticle FL is caused by the core of carbon nanoparticles (CNPs) and various emission centers on their surface, such as carbonyl, carboxyl, and hydroxyl groups. As CNPs could be exceptional candidates for detection technologies, the biocompatibility assays were performed with living COS-7 mammalian cells, showing a minimal negative impact on the living cells.

Published: April 2024

Abstract
Integrated photonics has been a promising platform for analog quantum simulation of condensed matter phenomena in strongly correlated systems. To that end, we explore the implementation of all-photonic quantum simulators in coupled cavity arrays with integrated ensembles of spectrally disordered emitters. Our model is reflective of color center ensembles integrated into photonic crystal cavity arrays. Using the Quantum Master equation and the Effective Hamiltonian approaches, we study energy band formation and wavefunction properties in the open quantum Tavis–Cummings–Hubbard framework. We find conditions for polariton creation and (de)localization under experimentally relevant values of disorder in emitter frequencies, cavity resonance frequencies, and emitter-cavity coupling rates. To quantify these properties, we introduce two metrics, the polaritonic and nodal participation ratios, that characterize the light-matter hybridization and the node delocalization of the wavefunction, respectively. These new metrics combined with the Effective Hamiltonian approach prove to be a powerful toolbox for cavity quantum electrodynamical engineering of solid-state systems.

Published: April 2024

Abstract
Mental health is a complex, multidimensional concept that goes beyond clinical diagnoses, including psychological distress, life stress, and well-being. In this study, we aimed to use unsupervised clustering approaches to identify multidimensional mental health profiles that exist in the population, and their associated service-use patterns. The data source was the 2012 Canadian Community Health Survey–Mental Health, linked to administrative health-care data; all Ontario, Canada, adult respondents were included. We used a partitioning around medoids clustering algorithm with Gower’s proximity to identify groups with distinct combinations of mental health indicators and described them according to their sociodemographic and service-use characteristics. We identified 4 groups with distinct mental health profiles, including 1 group that met the clinical threshold for a depressive diagnosis, with the remaining 3 groups expressing differences in positive mental health, life stress, and self-rated mental health. The 4 groups had different age, employment, and income profiles and exhibited differential access to mental health-care services. This study represents the first step in identifying complex profiles of mental health at the population level in Ontario. Further research is required to better understand the potential causes and consequences of belonging to each of the mental health profiles identified.

Abstract
Avanzando Caminos (Leading Pathways): The Hispanic/Latino Cancer Survivorship Cohort Study aims to examine the influence of sociocultural, medical, stress-related, psychosocial, lifestyle, behavioral, and biological factors on symptom burden, health-related quality of life, and clinical outcomes among Hispanics/Latinos who have been previously treated for cancer. Avanzando Caminos is a prospective, cohort-based study of 3000 Hispanics/Latinos who completed primary cancer treatment within the past 5 years that is representative of the general Hispanic/Latino population in the United States. Participants will complete self-report measures at baseline (time [T] 1), 6 months (T2), 1 year (T3), 2 years (T4), 3 years (T5), 4 years (T6), and 5 years (T7). Blood samples drawn for assessment of leukocyte gene expression, cardiometabolic markers, and genetic admixture will be collected at baseline (T1), 1 year (T3), 3 years (T5), and 5 years (T7). Medical and cancer characteristics and clinical outcomes will be extracted from the electronic medical record and/or state cancer registry at each time point. Data analysis will include general latent variable modeling and latent growth modeling. Avanzando Caminos will fill critical gaps in knowledge in order to guide future secondary and tertiary prevention efforts to mitigate cancer disparities and optimize health-related quality of life among Hispanic/Latino cancer survivors.
Impact of a calcium replacement protocol during massive transfusion in trauma patients at a level 2 trauma center
Authors: Shandaliy Yana , Busey Kirsten , Scaturo Nicholas 
Published: April 2024

Abstract

Purpose
Hypocalcemia is associated with increased mortality in trauma patients with hemorrhagic shock who require massive transfusion protocols (MTPs). Despite known risks of potentiating hypocalcemia with blood product administration, there is little research discussing appropriate calcium replacement. The purpose of this study was to evaluate the ability of a standardized calcium replacement protocol to reduce the incidence of hypocalcemia in trauma patients undergoing MTP.

Methods
This retrospective, single-center, pre-post study evaluated the use of a calcium replacement protocol during MTP. Adult trauma patients with MTP orders who received at least one “round” of product transfusion were included. Patients were excluded if their ionized calcium (iCa) levels were unavailable or they were transferred to a higher level of care within 4 hours of presentation. The primary outcome was incidence of hypocalcemia (iCa of &lt;1.1 mg/dL) within 24 hours of MTP initiation. Secondary endpoints included the incidence of severe hypocalcemia (iCa of &lt;0.9 mg/dL), time to first calcium dose, total calcium dose administered (mEq), resolution of hypocalcemia within 24 hours, hypercalcemia, adherence to the calcium replacement protocol, and mortality.

Results
The incidence of hypocalcemia within 24 hours was significantly lower in the postprotocol group (63% vs 95.2%; P = 0.006). There was not a significant difference in the incidence of severe hypocalcemia between the groups (39.1% vs 69.1%; P = 0.083). Time to first calcium dose was significantly shorter in postprotocol patients compared to preprotocol patients (median [interquartile range], 5.5 [0-21] minutes vs 43 [22.8-73] minutes; P &lt; 0.0001), and postprotocol patients were administered more calcium during MTP (40.8 [27.2-54.4] mEq vs 27.2 [14-32.2] mEq; P = 0.005). Adherence to the protocol was seen in only 37% of patients in the postprotocol group. There was no difference in the rate of adverse events or overall mortality.

Conclusion
Trauma patients who received massive transfusion of blood products had a significantly lower incidence of hypocalcemia after a calcium replacement protocol was implemented.
Does lower water availability limit stem CO2 efflux of oak and hornbeam coppices?
Authors: Darenova Eva , Knott Robert , Vichta Tomáš 
Published: April 2024

Abstract
Recent changes in water availability can be crucial for the development, growth and carbon budget of forests. Therefore, our aim was to determine the effect of reduced throughfall and severe summer drought on stem CO2 efflux as a function of temperature and stem increment. Stem CO2 efflux was measured using the chamber method on oak and hornbeam under four treatments: coppice, thinned coppice, and both coppice and thinned coppice with 30 %-reduced throughfall. The first year of the experiment had favourable soil water availability and the second year was characterized by a dry summer. While reduced throughfall had no effect on stem CO2 efflux, the summer drought decreased efflux by 43–81 % during July and August. The stem CO2 efflux was reduced less severely (by 13–40 %) in September when the drought persisted but the stem increment was already negligible. The stem increment was also strongly affected by the drought, which was reflected in its paired relationship with stem CO2 efflux over the two experimental years. The study showed that summer dry periods significantly and rapidly reduce stem CO2 efflux, whereas a constant 30 % rainfall reduction needs probably a longer time to affect stem properties, and indirectly stem CO2 efflux.

Abstract

Background
Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease with a considerable disease burden. Existing treatment options are limited and often suboptimal; a high unmet need exists for effective targeted therapies.

Objectives
To explore the effects of spesolimab treatment in patients with HS.

Methods
This randomized double-blind placebo-controlled proof-of-clinical-concept (PoCC) study was conducted at 25 centres across 12 countries from 3 May 2021 to 21 April 2022. Patients had moderate-to-severe HS for ≥ 1 year before enrolment. Patients were randomized (2 : 1) to receive a loading dose of 3600-mg intravenous spesolimab (1200 mg at weeks 0, 1 and 2) or matching placebo, followed by maintenance with either 1200-mg subcutaneous spesolimab every 2 weeks from weeks 4 to 10 or matching placebo. The primary endpoint was the percentage change from baseline in total abscess and inflammatory nodule (AN) count at week 12. Secondary endpoints were the absolute change from baseline in the International Hidradenitis Suppurativa Severity Score System (IHS4), percentage change from baseline in draining tunnel (dT) count, the proportion of patients achieving a dT count of 0, absolute change from baseline in the revised Hidradenitis Suppurativa Area and Severity Index (HASI-R), the proportion of patients achieving Hidradenitis Suppurativa Clinical Response (HiSCR50), the proportion of patients with ≥ 1 flare (all at week 12) and patient-reported outcomes.

Results
In this completed trial, randomized patients (n = 52) received spesolimab (n = 35) or placebo (n = 17). The difference vs. placebo in least squares mean is reported. At week 12, the percentage change in total AN count was similar between treatment arms: –4.1% [95% confidence interval (CI) –31.7 to 23.4]. There was greater numerical improvement in the spesolimab arm, as measured by IHS4 (13.9, 95% CI –25.6 to –2.3); percentage change from baseline in dT count (–96.6%, 95% CI –154.5 to –38.8); and the proportion of patients achieving a dT count of 0 (18.3%, 95% CI –7.9 to 37.5). Spesolimab treatment also improved HASI-R and HiSCR50 vs. placebo. Spesolimab demonstrated a favourable safety profile, similar to that observed in trials in other diseases.

Conclusions
This exploratory PoCC study supports the development of spesolimab as a new therapeutic option in HS.

Published: April 2024

Abstract

Objective
This study aimed to establish the first-ever MRI classification of uterosacral ligament (USL) involvement in deep infiltrating endometriosis (DIE), based on reliable preoperative MRI features correlated with positive predictive values (PPVs) determined through histopathological analysis.

Methods
Twenty-two women underwent surgery with histopathology due to symptoms highly suggestive of endometriosis. The 22 preoperative MRIs were analysed retrospectively, blinded to histopathology, and a classification of the preoperative aspect of USLs linked to PPVs was designed.

Results
According to their aspects, 6 radiological types of USL were identified. The “L-category” corresponded to linear types with regular or irregular margins, including types 1, 2, 3A, and 3B. The “N-category” corresponded to haemorrhagic or nodular types, including types 4, 5A, 5B, and 6. For the L-category, PPVs ranged from 75% to 88%, depending on the USL radiological type. For the N-category, PPVs were 100% for each type. In women with endometriosis symptoms, MRI underestimated USL involvement, especially for type 1. Among the 6 uteri with lateral deviation, only one false-positive result concerning the stretched USL was induced.

Conclusions
In women with endometriosis symptoms, our MRI classification identified 2 USL categories, corresponding to 2 kinds of PPV; in these symptomatic patients, a normal MRI does not rule out a DIE diagnosis.

Advances in knowledge
Our MRI classification of USL involvement in endometriosis may be used as a non-invasive staging of the disease, making it much clearer for clinicians and patients. Hence, we are able to propose a suitable diagnostic and therapeutic procedure for each radiological type.
