The Macro- And Micro-Anatomy Of Primate Volar Surfaces, Amanda Kathryn Kingston

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

The soft tissues of the volar surfaces of primate hands and feet are the primary point of interaction between an individual animal and its environment and, as such, are likely to be under strong functional selection. These tissues serve three major functions: 1) force attenuation – the volar fat pads assist in attenuating reaction forces generated during grasping locomotion; 2) friction enhancement – the volar fat pads also act as viscoelastic surfaces that increase the coefficient of friction between the pads and substrate at low body weights; in addition, the ridged volar skin interlocks with and thus increases friction with …

Reduced Snow Cover Alters Root-Microbe Interactions And Decreases Nitrification Rates In A Northern Hardwood Forest, Patrick O. Sorensen, Pamela H. Templer, Lynn M. Christenson, Jorge Durán, Timothy J. Fahey, Melany C. Fisk, Peter M. Groffman, Jennifer L. Morse, Adrien C. Finzi

Environmental Science and Management Faculty Publications and Presentations

Snow cover is projected to decline during the next century in many ecosystems that currently experience a seasonal snowpack. Because snow insulates soils from frigid winter air temperatures, soils are expected to become colder and experience more winter soil freeze-thaw cycles as snow cover continues to decline. Tree roots are adversely affected by snowpack reduction, but whether loss of snow will affect root-microbe interactions remains largely unknown. The objective of this study was to distinguish and attribute direct (e.g., winter snow-and/ or soil frost-mediated) vs. indirect (e.g., root-mediated) effects of winter climate change on microbial biomass, the potential activity of …

The Irrelevance Of Nanotechnology Patents, Emily Michiko Morris

Faculty Scholarly Works

Although scientists have for decades now had the ability to manipulate matter at the atomic level, we have yet to see the nanotechnological revolution that these scientists predicted would follow. Despite the years of effort and billions of dollars that have been invested into research and development thus far, nanotechnology has yielded surprisingly few end-user applications. A number of commentators have blamed this lack of progress on the Bayh-Dole Act and other changes to patent law, arguing that, although these laws are supposed to stimulate technological development, they have in fact had the exact opposite effect when it comes to …

Regional Mapping Of Flow And Wall Characteristics Of Intracranial Aneurysms, Juan R. Cebral, Xinjie Duan, Piyusha S. Gade, Bong Jae Chung, Fernando Mut, Khaled Aziz, Anne M. Robertson

Department of Applied Mathematics and Statistics Faculty Scholarship and Creative Works

The evolution of intracranial aneurysms (IAs) is thought to be driven by progressive wall degradation in response to abnormal hemodynamics. Previous studies focused on the relationship between global hemodynamics and wall properties. However, hemodynamics, wall structure and mechanical properties of cerebral aneurysms can be non-uniform across the aneurysm wall. Therefore, the aim of this work is to introduce a methodology for mapping local hemodynamics to local wall structure in resected aneurysm specimens. This methodology combines image-based computational fluid dynamics, tissue resection, micro-CT imaging of resected specimens mounted on 3D-printed aneurysm models, alignment to 3D vascular models, multi-photon microscopy of the …

How Intermediate Capacity Modes Provide Accessibility And Resilience In Metropolitan Transit Networks: Insights From A Global Study Of 19 Cities, Jan Scheurer

Journal of Public Transportation

Drawing on the Spatial Network Analysis of Multimodal Urban Transport Systems (SNAMUTS) accessibility tool, this paper introduces comparative results of public transport network performance measures in 19 metropolitan regions in developed countries. These results are assessed typologically and functionally to highlight the contribution of each common public transport mode to maximize (or not) the integration of transport networks with the urban structure to optimize accessibility outcomes. It is shown that the capacity and performance spectrum embodied by each mode represents a gradual scale that allocates a specific niche to intermediate modes, particularly trams that are present in half the cities …

Biology Faculty Publications

During a 17-yr telemetry study, we examined the diet and ambush behavior of a population of Crotalus horridus in southeastern Virginia. Forty dietary items were identified from 37 fecal samples. We documented 722 instances of snakes in an ambush posture, 61% of which were in a vertical-tree posture, as if hunting arboreal prey at the base of a tree. The most common prey items were Eastern Gray Squirrels (Sciurus carolinensis), which accounted for 45% of all dietary items and represented an estimated 78% of total biomass consumed by C. horridus. Prey was not consumed in proportion to availability, based on …

Specific Emotions And Altruistic Decision Making - A Study In Relational Perspective, Srinwanti Hazra Chaudhury

Psychology Theses - Archive

The role of emotions in decision making processes has long been of interest to researchers due to its relevance in our daily consumption decisions. Recent experimental studies have suggested that specific emotions prime different implicit goals. However, despite their importance in applied settings, there has been a lack of clear understanding of how specific emotions might influence prosocial activities, such as donating money to charitable organizations, or engaging in volunteering behavior. To explore the effect of specific emotions on altruism, a between-subjects study was conducted to examine four emotion conditions (e.g., anxiety, sadness, pride, hope) along with a control neutral …

Dynamic Wireless Interrogation Of Antenna‐Sensor In Harsh Environment, Jun Yao

Electrical Engineering Dissertations - Archive

Microstrip antenna-sensor has received considerable interests in recent years due to its simple configuration, compact size, and multi-modality sensitivity. Due to its simple and conformal planar configuration, antenna-sensor can be easily attached on the structure surface for Structure Health Monitoring (SHM). As a promising sensor, the resonant frequency of the antenna-sensor is sensitive to different structure properties: such as planar stress, temperature, pressure and moisture. As a passive antenna, antenna-sensor’s resonant frequency can be wirelessly interrogated at a middle range distance without using an on-board battery. However, a major challenge of antenna-sensor’s wireless interrogation is to isolate the antenna backscattering …

Associations Between Weight Status And Post-Tonsillectomy Pain Experiences In Children: A Retrospective Study, Shirley Smith Martin

Nursing Dissertations - Archive

There has been little research on pain outcomes in obese and overweight (OB/OW) children undergoing surgery. Tonsillectomy or adenotonsillectomy (T&A) is one of the most common painful surgeries performed in children. The estimated number of OB/OW children undergoing T&A each year approaches 200,000. Post-tonsillectomy pain (PTP) management after surgery is complicated by potential for airway obstruction or altered drug metabolism in OB/OW children. The purpose of this study was to examine associations between weight status and PTP outcomes in the PACU. A retrospective correlational cohort design was used. Data were obtained from 180 electronic health records of children who had …

Uniform Micro-Patterning Of An Arbitrary Surface, Viraj Rajendra Kulkarni

All Theses

According to the literature, creating specific micro-level patterns on some surfaces can significantly reduce friction. To this effect, a method is presented to create a regular pattern of micro-level indentations on any irregular surface. Creating a uniform pattern on a regular surface is possible using commercial CAD software, where regular surface is the surface obtained by extrusion or revolution of a 2D sketch along any curve. But, it is complicated and often incorrect for irregular surfaces. The thesis presents the approach followed to create parameterized regular patterns on arbitrary surfaces. Three different algorithms are presented, each achieving a progressively increased …

Extending The Reach Of Directional Dark Matter Experiments Through Novel Detector Technologies, Nguyen S. Phan

Physics & Astronomy ETDs

Dark matter is believed to comprise over 80% of the matter in the Universe. Its composition could be in the form of weakly interacting massive particles (WIMPs), which are predicted by extensions of the Standard Model, namely supersymmetric theories. Even though hints of its existence were detected in astronomical observations over eighty years ago, its detection through means other than the gravitational influence on observable luminous matter still eludes us.

Currently, there are many ongoing direct detection experiments, that aim to measure the signals left by the elastic scattering of WIMPs with nuclei in the detector target material. The detection …
