Impacts of EPA's finalized power plant greenhouse gas standards.

Emissions reductions may be met with relatively small costs.

A database of hourly wind speed and modeled generation for US wind plants based on three meteorological models.

In 2022, wind generation accounted for ~10% of total electricity generation in the United States. As wind energy accounts for a greater portion of total energy, understanding geographic and temporal variation in wind generation is key to many planning, operational, and research questions. However, in-situ observations of wind speed are expensive to make and rarely shared publicly.

Emissions and energy impacts of the Inflation Reduction Act.

Economy-wide emissions drop 43 to 48% below 2005 levels by 2035 with accelerated clean energy deployment.

Levelized cost-based learning analysis of utility-scale wind and solar in the United States.

Learning curves play a central role in power sector planning. We improve upon past learning curves for utility-scale wind and solar through a combination of approaches. First, we generate plant-level estimates of the levelized cost of energy (LCOE) in the United States, and then use LCOE, rather than capital costs, as the dependent variable.

Income-targeted marketing as a supply-side barrier to low-income solar adoption.

Low- and moderate-income (LMI) households remain less likely to adopt rooftop solar photovoltaics (PV) than higher-income households. A transient period of inequitable adoption is common among emerging technologies but stakeholders are calling for an accelerated transition to equitable rooftop PV adoption. To date, researchers have focused on demand-side drivers of PV adoption inequity, but supply-side factors could also play a role.

A universal 3D imaging sensor on a silicon photonics platform.

Accurate three-dimensional (3D) imaging is essential for machines to map and interact with the physical world. Although numerous 3D imaging technologies exist, each addressing niche applications with varying degrees of success, none has achieved the breadth of applicability and impact that digital image sensors have in the two-dimensional imaging world. A large-scale two-dimensional array of coherent detector pixels operating as a light detection and ranging system could serve as a universal 3D imaging platform.

A pediatric high-flow nasal cannula protocol standardizes initial flow and expedites weaning.

Objective: Respiratory illnesses compose the most common diagnoses of patients admitted to pediatric intensive care units. In pediatrics, high-flow nasal cannula (HFNC) therapy is an intermediate level of respiratory support with variability in practice. We conducted a pre-post intervention study of patients placed on HFNC therapy before and after the implementation of an HFNC protocol.

Grand challenges in the science of wind energy.

Harvested by advanced technical systems honed over decades of research and development, wind energy has become a mainstream energy resource. However, continued innovation is needed to realize the potential of wind to serve the global demand for clean energy. Here, we outline three interdependent, cross-disciplinary grand challenges underpinning this research endeavor.

Integrating Palliative Care in Pediatric Oncology: Evidence for an Evolving Paradigm for Comprehensive Cancer Care.

Background: The demonstrated benefit of integrating palliative care (PC) into cancer treatment has triggered an increased need for PC services. The trajectory of integrating PC in comprehensive cancer centers, particularly pediatric centers, is unknown. We describe our 8-year experience of initiating and establishing PC with the Quality of Life Service (QoLS) at St.

Contact angle, protein adsorption and osteoblast precursor cell attachment to chitosan coatings bonded to titanium.

Chitosan, a derivative of the bio-polysaccharide chitin, has shown promise as a bioactive material for implant, tissue engineering and drug-delivery applications. The aim of this study was to evaluate the contact angle, protein adsorption and osteoblast precursor cell attachment to chitosan coatings bonded to titanium. Rough ground titanium (Ti) coupons were solution cast and bonded to 91.

Chitosan: potential use as a bioactive coating for orthopaedic and craniofacial/dental implants.

Chitosan is a biopolymer that exhibits osteoconductive, enhanced wound healing and antimicrobial properties which make it attractive for use as a bioactive coating to improve osseointegration of orthopaedic and craniofacial implant devices. Coatings made from 91.2% de-acetylated chitosan were chemically bonded to titanium coupons via silane-glutaraldehyde molecules.

Relation between intracranial pressure, computed tomographic lesion, and neuropsychological outcome.

Long-term neuropsychological recovery of 24 severe head-injured patients was examined and correlated with acute measurements of intracranial pressure (ICP) and diffuse computed tomographic (CT) lesions. Intracranial hypertension (ICP greater than or equal to 20 mm Hg) was present acutely in 12 patients and absent in 12 patients. CT diagnoses of diffuse swelling (DS) was present in 12 patients, and diffuse axonal injury (DAI) in 12 patients.

The shaken baby syndrome. A clinical, pathological, and biomechanical study.

Because a history of shaking is often lacking in the so-called "shaken baby syndrome," diagnosis is usually based on a constellation of clinical and radiographic findings. Forty-eight cases of infants and young children with this diagnosis seen between 1978 and 1985 at the Children's Hospital of Philadelphia were reviewed. All patients had a presenting history thought to be suspicious for child abuse, and either retinal hemorrhages with subdural or subarachnoid hemorrhages or a computerized tomography scan showing subdural or subarachnoid hemorrhages with interhemispheric blood.

Influence of lesions detected by computed tomography on outcome and neuropsychological recovery after severe head injury.

Outcome at 6 months after severe head injury was determined in 117 patients whose computed tomographic (CT) examinations demonstrated diffuse axonal injury (DAI), diffuse swelling (DS), or focal injuries. Neuropsychological sequelae were ascertained from two examinations in 30 of the conscious survivors within the 1st year after injury. Outcome differences varied with the type of CT lesion.

Relation of visual field defects to neuropsychological outcome after closed head injury.

Neuropsychological outcome within two years after injury was determined in 159 head injured patients who were classified into three groups according to the presence of either unilateral, bilateral, or no visual field defects (VFDs). The VFDs occurred irrespective of injury severity as determined by the Glasgow coma scale, or social outcome as determined by the Glasgow outcome scale. Differences among the three visual field groups were obtained for several neuropsychological functions: intelligence, memory, learning, acquired verbal skills, visuospatial skills, and visuomotor speed.
