Adaptive focusing for wideband beamforming in multipath environments.

This paper addresses achieving the high time-bandwidth product necessary for low signal-to-noise ratio (SNR) target detection and localization in complex multipath environments. Time bandwidth product is often limited by dynamic environments and platform maneuvers. This paper introduces data-driven wideband focusing methods for passive sonar that optimize parameterized unitary matrices to align signal subspaces across the frequency band without relying on wave propagation models which are subject to mismatch in complex multipath environments.

Restoring cefepime activity against multidrug-resistant KPC-producing by combination with boronic acid inhibitors, MB076 and S02030.

Foremost in the design of new β-lactamase inhibitors (BLIs) are the boronic acid transition state inhibitors (BATSIs). Two highly potent BATSIs being developed are S02030 and MB076 strategically designed to be active against cephalosporinases and carbapenemases, especially KPC. When combined with cefepime, S02030 and MB076 demonstrated potent antimicrobial activity against laboratory and clinical strains of expressing a variety of class A and class C β-lactamases, including and .

Epigenetic mechanisms underlying endometrial cancer (EC) outcomes: race-specific patterns of DNA methylation associated with molecular subtypes and survival.

Endometrial cancer [EC] is the fourth most common cancer in women in the United States. Stark racial disparities are present in EC outcomes in which Black women have significantly higher EC-related mortality than White women. The social and biologic factors that contribute to these disparities are complex, and may include racial differences in epigenetic landscapes.

Combining Hyperpolarized Xe MR Imaging and Spectroscopy to Non-Invasively Estimate Pulmonary Vascular Resistance.

Hyperpolarized Xe MRI/MRS enables quantitative mapping of function in lung airspaces, membrane tissue, and red blood cells (RBCs) within the pulmonary capillaries. The RBC signal also exhibits cardiogenic oscillations that are reduced in pre-capillary pulmonary hypertension (PH). This effect is obscured in patients with concomitant defects in transfer from airspaces to RBCs, which increase RBC oscillation amplitudes.

Wildland Firefighters Suffer Increasing Risk of Job-Related Death.

Wildland firefighting is a niche specialization in the fire service - inherently dangerous with unique risks. Over the past decade, fatalities amongst all firefighters have decreased; however, wildland firefighter fatalities have increased. This subject has only been described in the grey literature, and a paucity of medical literature exists.

The talk and walk in Black families: Exploring racial socialization content and competency in the context of parental worries about racial profiling and adolescents' internalizing outcomes.

Although many parents worry that their child will be the target of racial profiling, there is a dearth of literature on how parental worries about children facing racism are linked to racial socialization (RS) practices and youth internalizing symptoms. Additionally, it is unclear how RS content relative to competency may uniquely influence whether and how parental worries influence youth internalizing outcomes. Using data from 203 Black parents (M = 44.

The results underscore the need for a more coordinated approach to GenAI governance, emphasizing collaboration among senior leaders, clinicians, information technology staff, and researchers.

Drought as an emergent driver of ecological transformation in the twenty-first century.

Under climate change, ecosystems are experiencing novel drought regimes, often in combination with stressors that reduce resilience and amplify drought's impacts. Consequently, drought appears increasingly likely to push systems beyond important physiological and ecological thresholds, resulting in substantial changes in ecosystem characteristics persisting long after drought ends (i.e.

Relationship between fluid intake, hydration status and cortisol dynamics in healthy, young adult males.

Background: Previous studies have identified links between fluid intake, hydration related hormones and cortisol measured at one timepoint but have not considered how hydration may influence cortisol dynamics throughout the day. This study assessed associations between hydration status (copeptin, urinary osmolality, urine volume) and habitual fluid intake with cortisol dynamics.

Methods: The day before (DB) a 6-h laboratory visit, 29 male participants (age, 23±4y; BMI, 25.

Identifying enablers and barriers to teleultrasound use for remote settings: A scoping review.

Introduction/purpose: Teleultrasound connects expert point-of-care ultrasound (POCUS) users with remote community and rural sites. Evolving technologies including handheld devices, upgraded image quality, and the ability to transmit over low bandwidth connections increase POCUS education, accessibility, and clinical integration. Potential teleultrasound venues include low-resource settings, prehospital care, and austere environments (high altitudes, microgravity, conflict zones, etc.

Integrating biophysical modeling, quantum computing, and AI to discover plastic-binding peptides that combat microplastic pollution.

Methods are needed to mitigate microplastic (MP) pollution to minimize their harm to the environment and human health. Given the ability of polypeptides to adsorb strongly to materials of micro- or nanometer size, plastic-binding peptides (PBPs) could help create bio-based tools for detecting, filtering, or degrading MNP pollution. However, the development of such tools is prevented by the lack of PBPs.

Striving for early effective glycaemic and weight management in type 2 diabetes: A narrative review.

Despite the recognition by key guidelines that achieving early glycaemic control has important benefits in individuals with type 2 diabetes (T2D) and that addressing excess adiposity is one of the central components of comprehensive person-centred T2D care, a substantial proportion of individuals with T2D do not meet their metabolic treatment goals. Prior treatment paradigms were limited by important treatment-associated risks such as hypoglycaemia and body weight gain. Therefore, a more conservative, sequential approach to treatment was typically utilized.

Inpp5e Is Critical for Photoreceptor Outer Segment Maintenance.

In humans, inositol polyphosphate-5-phosphatase e (INPP5E) mutations cause retinal degeneration as part of Joubert and MORM syndromes and can also cause non-syndromic blindness. In mice, mutations cause a spectrum of brain, kidney, and other anomalies and prevent the formation of photoreceptor outer segments. To further explore the function of Inpp5e in photoreceptors, we generated conditional and inducible knockouts of mouse Inpp5e where the gene was deleted either during outer segment formation or after outer segments were fully formed.

Parental Style, Grandchild Problematic Behaviors, and Parental Role Demands Among Grandparent Caregivers.

The present study evaluates the impact of grandchild distress on parental competence as mediated by Baumrind's parental styles in a sample of 238 custodial grandparents ( age = 58.06). AMOS structural equation findings yielded a model which indicated that both the Laissez-Faire and Authoritarian styles each predicted role stress and/or parental efficacy.

Objective: To assess how patient and caregiver factors influence caregiver readiness for hospital discharge in palliative care patients.

Study Setting And Design: This transitional care study uses cross-sectional data from a randomized controlled trial conducted from 2018 to 2023 testing an intervention for caregivers of hospitalized adult patients with a serious or life-limiting illness who received a palliative care consult prior to transitioning out of the hospital.

Data Sources And Analytical Sample: Caregiver readiness was measured with the Family Readiness for Hospital Discharge Scale (n = 231).

TRIM9 Controls Growth Cone Responses to Netrin Through DCC and UNC5C.

The guidance cue netrin-1 promotes both growth cone attraction and growth cone repulsion. How netrin-1 elicits diverse axonal responses, beyond engaging the netrin receptor DCC and UNC5 family members, remains elusive. Here, we demonstrate that murine netrin-1 induces biphasic axonal responses in cortical neurons: Attraction at lower concentrations and repulsion at higher concentrations using both a microfluidic-based netrin-1 gradient and bath application of netrin-1.

Effects of Interaural Latency and Frequency Mismatch on Speech Recognition for Bimodal Cochlear Implant Users.

Objectives: Bimodal cochlear implant (CI) users vary in speech recognition outcomes. This variability may be influenced partly by the CI and contralateral hearing aid (HA) programming procedures, which can result in mismatches in latency and frequency. We assessed the performance of bimodal listeners when latency mismatches were corrected and analyzed how frequency mismatches influenced outcomes.

Step Edge Defects Have Nanoscale Impact on the Electronic Structure in Semiconducting Transition Metal Dichalcogenide Electrocatalysts.

This work uses MoTe single crystals to address the challenge in heterogeneous catalysis of identifying active sites and determining the electronic factors responsible for catalytic activity. We find that for semiconducting MoTe, spots that fall along step edges show more catalytic activity than spots that fall solely on the basal plane. In contrast, for a semimetallic phase of MoTe, there is no measurable difference between the H evolution activity at the step edges and at the basal plane, indicating that the active sites for H evolution catalysis on transition metal dichalcogenides are phase dependent.

Changes in the critical nutrient content of packaged foods and beverages after the full implementation of the Chilean Food Labelling and Advertising Law: a repeated cross-sectional study.

Background: Chile's Food Labelling Law was implemented in three phases with increasingly stricter limits. After initial implementation, sugars and sodium decreased in packaged foods, with no significant changes for saturated fats. It is unclear whether full implementation is linked with further reformulation or if producers reversed changes due to consumers' preferences.

Rome Foundation Working Team Report on overlap in disorders of gut-brain interaction.

In patients with disorders of gut-brain interaction (DGBI), overlapping non-gastrointestinal conditions such as fibromyalgia, headaches, gynaecological and urological conditions, sleep disturbances and fatigue are common, as is overlap among DGBI in different regions of the gastrointestinal tract. These overlaps strongly influence patient management and outcome. Shared pathophysiology could explain this scenario, but details are not fully understood.
