All-optical packet-header-recognition techniques (2003)

As transmission speeds in the network core approach 40 Gb/s and beyond, the need to make faster routing decisions becomes increasingly evident. It may, therefore, be important to determine where it may be feasible to employ optical techniques to aid the electronics in making rapid routing decisions In conventional Internet routers, packets are switched to their destinations by interrogating their 24-bit destination IP addresses and matching them to entries in a large routing table using complicated longest prefix matching algorithms. Given that most core routers have only four to eight outgoing ports, it may be possible to determine a packet's outgoing port by looking at only a small subset of the 24 bits in the destination address. It may be feasible to build an optical bypass to vastly accelerate a conventional router.

Experimental Validation of Replaceable Shear Links for Eccentrically Braced Steel Frames (2011)

In the current design of steel eccentrically braced frames (EBFs), the yielding link is coupled with the floor beam. This often results in oversized link elements, which leads to overdesigned structures and foundations. In addition, the beams are expected to sustain significant damage through repeated inelastic deformations under design-level earthquakes, and thus the structure may require extensive repair or replacement. These drawbacks can be mitigated by designing EBFs with replaceable shear links. Two different replaceable link types with alternate section profiles, connection configurations, welding details, and intermediate stiffener spacings were tested. A total of 13 cyclic quasi-static full-scale cyclic tests were performed, including tests on EBFs with replaceable shear links, to study their inelastic seismic performance. The links exhibited a very good ductile behavior, developing stable and repeatable yielding. Additional inelastic rotation capacity can be achieved with bolted replaceable links when bolt bearing deformations are allowed to occur. The on-site replaceability of the link sections is confirmed even in the presence of residual deformations of 0.5% drift.
Open‐Structured V2O5·nH2O Nanoflakes as Highly Reversible Cathode Material for Monovalent and Multivalent Intercalation Batteries (2017)

The high‐capacity cathode material V 2 O 5 · n H 2 O has attracted considerable attention for metal ion batteries due to the multielectron redox reaction during electrochemical processes. It has an expanded layer structure, which can host large ions or multivalent ions. However, structural instability and poor electronic and ionic conductivities greatly handicap its application. Here, in cell tests, self‐assembly V 2 O 5 · n H 2 O nanoflakes shows excellent electrochemical performance with either monovalent or multivalent cation intercalation. They are directly grown on a 3D conductive stainless steel mesh substrate via a simple and green hydrothermal method. Well‐layered nanoflakes are obtained after heat treatment at 300 °C (V 2 O 5 ·0.3H 2 O). Nanoflakes with ultrathin flower petals deliver a stable capacity of 250 mA h g −1 in a Li‐ion cell, 110 mA h g −1 in a Na‐ion cell, and 80 mA h g −1 in an Al‐ion cell in their respective potential ranges (2.0–4.0 V for Li and Na‐ion batteries and 0.1–2.5 V for Al‐ion battery) after 100 cycles.

TNF‐α increases ubiquitin‐conjugating activity in skeletal muscle by up‐regulating UbcH2/E2 20k (2003)

In some inflammatory diseases, TNF-alpha is thought to stimulate muscle catabolism via an NF-kappaB-dependent process that increases ubiquitin conjugation to muscle proteins. The transcriptional mechanism of this response has not been determined. Here we studied the potential role of UbcH2, a ubiquitin carrier protein and homologue of murine E220k. We find that UbcH2 is constitutively expressed by human skeletal and cardiac muscles, murine limb muscle, and cultured myotubes. TNF-alpha stimulates UbcH2 expression in mouse limb muscles in vivo and in cultured myotubes. The UbcH2 promoter region contains a functional NF-kappaB binding site; NF-kappaB binding to this sequence is increased by TNF-alpha stimulation. A dominant negative inhibitor of NF-kappaB activation blocks both UbcH2 up-regulation and the increase in ubiquitin-conjugating activity stimulated by TNF-alpha. In extracts from TNF-alpha-treated myotubes, ubiquitin-conjugating activity is limited by UbcH2 availability; activity is inhibited by an antiserum to UbcH2 or a dominant negative mutant of UbcH2 and is enhanced by wild-type UbcH2. Thus, UbcH2 up-regulation is a novel response to TNF-alpha/NF-kappaB signaling in skeletal muscle that appears to be essential for the increased ubiquitin conjugation induced by this cytokine.
Superiority of Freehand Pointing (2013)

There is a possibility that computer mice may be replaced with eye-gaze or touchscreen technologies. Hence, it is imperative that we investigate the effect of the type of input device in conditions having lateral constraints. A set of tracks with different levels of difficulty were tested. The type of device had little influence on movement time for ballistic steering tasks, while movement time was affected by the type of device used in visually controlled steering tasks. It was also found that resting the forearm increased movement time. Subjective evaluations indicated that control is easier with freehand pointing. Considering both comfort and performance it appears that freehand pointing, when resting the forearm, is optimal for a touchscreen.
Energy Consumption of a LoRaWAN Network using Jarvis Algorithm (2020)

Energy consumption in LPWANs, such as LoRaWAN, plays an important role in determining the lifetime of wireless sensor networks motes. In this paper, the use of different battery technologies and the impact of the media access control layer (MAC) and physical layer (PHY) are studied. Among the metrics monitored in this scenario, it is energy efficiency and its impact on battery life for better performance. The Jarvis algorithm its run on the sensor network to examine the impact on the MAC and physical layer of LoRa. Its parameters such as spreading factor, channel activity detection, code rate and channel frequencies on the consumption of Energy; Executing the Jarvis algorithm showed that both technologies discharge in a similar way, but lithium batteries increase their resistance to discharge for a longer time and are more profitable when executing the Jarvis algorithm.
A versatile 2π‐tilting device for fluorescence microscopes (1994)

A tilting device for biological specimens (rotation angle up to 2π), especially fluorescence‐labelled cell nuclei, was developed. It consists of a quartz glass capillary and a mounting adapter for the microscope stage. The applicability of the device was tested for several epifluorescence and confocal scanning laser fluorescence microscopes. The axis of rotation is perpendicular to the optical axis of the microscope. The capillary can be tilted around its axis at any desired angle or in equiangular steps. This can be done manually or by remote control using a stepping motor. The three‐dimensional (3‐D) image‐forming properties of the capillary system were experimentally examined using an inverse confocal scanning laser microscope. The results were compared with measurements obtained from the same microscope with the standard stage for plane slides with cover glasses. The measured point spread function suggested that in spite of aberration effects, the optical arrangement used allows a gain in the 3‐D resolution by tilting the object. A low‐cost, fully automated 3‐D imaging system was built on the basis of a conventional epifluorescence microscope with a cooled black‐and‐white CCD camera. The system was operated by a personal computer. The online visualization (‘movie’) of rotating objects indicates the feasibility of the system.
Electro‐optical characteristics of ion‐beam‐aligned FFS‐LCDs on diamond‐like‐carbon thin film (2005)

Abstract— A fringe‐field‐switching (FFS) mode cell having LC alignment has been developed by using a non‐rubbing method, a ion‐beam‐alignment method on a‐C:H thin film, to analyze the electro‐optical characteristics of this cell. The suitable inorganic thin film for FFS‐LCDs and the alignment capabilities of nematic liquid crystal (NLC) have been studied. An excellent voltage‐transmittance ( V‐T ) and response‐time curve for the ion‐beam‐aligned FFS‐LCDs were observed using oblique ion‐beam exposure on DLC thin films.
Infrared Fingerprint Engineering: A Molecular‐Design Approach to Long‐Wave Infrared Transparency with Polymeric Materials (2019)

Abstract Optical technologies in the long‐wave infrared (LWIR) spectrum (7–14 μm) offer important advantages for high‐resolution thermal imaging in near or complete darkness. The use of polymeric transmissive materials for IR imaging offers numerous cost and processing advantages but suffers from inferior optical properties in the LWIR spectrum. A major challenge in the design of LWIR‐transparent organic materials is that nearly all organic molecules absorb in this spectral window which lies within the so‐called IR‐fingerprint region. We report on a new molecular‐design approach to prepare high refractive index polymers with enhanced LWIR transparency. Computational methods were used to accelerate the design of novel molecules and polymers. Using this approach, we have prepared chalcogenide hybrid inorganic/organic polymers (CHIPs) with enhanced LWIR transparency and thermomechanical properties via inverse vulcanization of elemental sulfur with new organic co‐monomers.
Measurements of Ambipolar Seebeck Coefficients in High‐Mobility Diketopyrrolopyrrole Donor–Acceptor Copolymers (2017)

Abstract The Seebeck coefficient of both electrons and holes in a family of ambipolar diketopyrrolopyrrole copolymers is investigated using field‐effect gated measurements. It is found that at high carrier concentrations the magnitude of the Seebeck coefficients is not strongly dependent on the molecular structure of the backbone within this family of polymers. Additionally, the Seebeck coefficients of electrons and holes have very similar magnitudes showing that electrons and holes experience a similar energetic landscape. Subtle differences in the carrier concentration dependence between the polymers are observed, which are interpreted in terms of different degrees of energetic disorder on the basis of molecular dynamics and electronic structure simulations.
Modified Studio Lab Classroom Used To Teach Electrical And Computer Engineering To Non Engineers (2020)

This paper addresses a solution to the challenge of teaching Electrical and Computer Engineering to non-engineering majors. All non-engineering students at the Naval Academy are enrolled in a two course Electrical Engineering sequence as a core requirement. There are many challenges in teaching this type of course. For example, the students have various mathematical abilities, most being humanities majors while others may major in Math or Physics. There is a diversity of learning styles in this mixed student population and, as a result, we have chosen to implement an interactive learning environment which we have found to be very suitable. The approach is a hands-on, learn by doing, integrated laboratory/classroom approach. To accomplish this, we constructed several studio classrooms, modified versions of those in use at Rensselaer Polytechnic Institute (RPI). One major difference is the number of students per section; ours are much smaller than RPI. Another difference is the need to teach a variety of subjects in the same classroom/lab. The two-course sequence covers everything from basic circuits and motors/generators to digital communications and networks. Our class sizes are small and there is a great deal of interaction between the students, working in teams and individually. In this paper we shall address the preparations required to offer this course including the equipment set-up, the room layout, the syllabus, lesson objectives and scheduling of the rooms. The assessment of the success of this model will be addressed, although it may be years before we gather enough data to have any statistical significance. We illustrate the importance of cooperative and collaborative learning in this environment and show how we have integrated these concepts into the courses. Finally, we present an overall assessment of this course from both the students' and instructors' points of view.
Validation of recorded transvaginal ultrasound strain analysis for uterine peristalsis in non-pregnant uteri (2014)

The appearance of a unilateral Horner's syndrome after an anesthetic in the lateral recumbent position is reported. It was caused by a damage to the sympathetic nerve at the level of Th 1 probably due to the extreme lateral flexion of the cervical vertebral spine. The importance of correct positioning of the head during anesthesia is stressed.
P1‐081: MRI validation of the NINDS‐CSN proposed neuropsychological assessment protocol for vascular cognitive impairment (2009)

In 2005, the NINDS-Canadian Stroke Network sponsored a workshop to develop epidemiological, pathological, experimental, neuropsychological and imaging standards for the assessment of vascular cognitive impairment (VCI). From this workshop, 60, 30 and 5-minute neuropsychological protocols were developed to assess cognitive function. The current study presents preliminary results on the validation of the 60-minute protocol using MRI measures of macro- and micro-structural integrity of white matter (WM) in patients with recent ischemic stroke. Patients 6 to 18 months post-ischemic stroke were tested on the cognitive assessment protocols and had MRIs of the brain. Macro-structural integrity of WM was assessed using a FLAIR pulse sequence with semi-automated assessment of WM hyperintensities using SABRE. Micro-structural integrity of WM was assessed using diffusion tensor imaging (DTI) determined fractional anisotropy (FA) of radiologically defined normal appearing white matter (NAWM). Relationship of imaging markers to neuropsychological performance measures was assessed in a series of regressions controlling for estimates of pre-morbid IQ. 21 ischemic stroke patients (mean age 69.7 + 11.9 year; mean Barthel score = 87.6+ 19.5; mean MMSE = 27.3 + 3.2) were tested and imaged. The average standardized performance on the 60 minute neuropsychological screening test for the patients was z = -1.5 (range -4.9 to 0.2). The sample's average volume of SABRE determined WM hyperintensities was 11.7 + 21.8 cm3 and NAWM FA was 0.32 + 0.04. Overall, pre-morbid IQ, WM hyperintensities and NAWM integrity significantly predicted performance on the 60-minute protocol (F[3,18] = 8.02, p = .002), accounting for approximately 62% of the shared variance. Higher volumes of WM hyperintensities and lower NAWM FA values were associated with poorer cognitive performance. NAWM integrity and WM hyperintensities independently improved the predictive model over the use of estimated pre-morbid IQ alone (R2 change 0.26 and 0.13 respectively, both p's < .05). These results provide preliminary support for the NINDS-CSN workshop proposed neuropsychological protocol for VCI. Both the volume of FLAIR determined WM hyperintensities and NAWM integrity significantly and independently predicted cognitive performance even while controlling for pre-morbid IQ. This ongoing project is supported by the NIH (NS057514).

Toward a mechanistic understanding of electrocatalytic nanocarbon (2021)

Electrocatalytic nanocarbon (EN) is a class of material receiving intense interest as a potential replacement for expensive, metal-based electrocatalysts for energy conversion and chemical production applications. The further development of EN will require an intricate knowledge of its catalytic behaviors, however, the true nature of their electrocatalytic activity remains elusive. This review highlights work that contributed valuable knowledge in the elucidation of EN catalytic mechanisms. Experimental evidence from spectroscopic studies and well-defined molecular models, along with the survey of computational studies, is summarized to document our current mechanistic understanding of EN-catalyzed oxygen, carbon dioxide and nitrogen electrochemistry. We hope this review will inspire future development of synthetic methods and in situ spectroscopic tools to make and study well-defined EN structures.
Doped-Tin Oxide Aerogels in Dye-Sensitized Solar Cells (2014)

Aerogels are attractive structures due to their high surface area, high porosity and particle interconnectivity, which are desirable properties for many device applications. They can be made by a facile sol-gel synthesis from low-cost metal salts to produce monolithic gels. These are dried supercritically to avoid the collapse of the structure that occurs with surface tension at the liquid-gas interface. SnO 2 is a n-type, wide bandgap semiconductor. Doped SnO 2 materials can exhibit transparency throughout the visible range of the solar spectrum and low electrical resistivity. They are commonly used as transparent conducting electrodes (TCEs) for a wide array of applications including solar cell fabrication. Here, doped-SnO 2 aerogels are synthesized as bulk and thin film monoliths, the latter serving as porous electron collectors in dye-sensitized solar cells (DSCs). This thesis is an in-depth study of the effects of dopants, namely fluorine and antimony, in the properties of SnO 2 aerogels. First, the use of fluorine and antimony is investigated to understand the effect of these dopants on the physical and optoelectronic properties of the SnO 2 materials. Doped aerogels are then used as thin films and coated with conformal layers of TiO 2 to fabricate DSCs. Solar cell characterization, including performance analysis and electron kinetics in the device, is conducted to understand the advantages of this system compared to the traditional TiO 2 DSCs.
Capturing Carbon Dioxide from Air with Charged Sorbents (2023)

There is an urgent need for improved sorbents for the capture of carbon dioxide from the atmosphere, a process known as direct air capture. In particular, low-cost materials that can be regenerated at low temperatures would overcome the limitations of current technologies. In this work, we introduce an electrochemical method for preparing designer “charged-sorbent” materials and synthesise a hydroxide-functionalised activated carbon that can rapidly capture carbon dioxide from ambient air via (bi)carbonate formation. Unlike traditional bulk carbonates, material regeneration can be achieved at low temperatures (100 ºC), and the sorbent's conductive nature permits direct Joule heating regeneration. Given their highly tailorable pore environments and low cost, we anticipate that charged-sorbents will find numerous potential applications in chemical separations, catalysis, and beyond.
Responsiveness Index versus the RASS-Based Method for Adjusting Sedation in Critically Ill Patients (2021)

The Gut Microbiome in Autism: Study-Site Effects and Longitudinal Analysis of Behavior Change (2021)

Research relating gut microbiome composition to autism spectrum disorders (ASD) has produced inconsistent results, indicative of the disorder's complexity and the need for more sophisticated experimental designs. We address this need by (i) comparing gut microbiome composition between individuals with ASD and neurotypical controls in Arizona and Colorado using standardized DNA extraction and sequencing methods at both locations and (ii) longitudinally evaluating the gut microbiome's relationship to autism behavioral severity, diet, and gastrointestinal symptoms. Gut microbiome composition differed between individuals in Arizona and individuals in Colorado, and gastrointestinal symptoms were significantly higher in ASD individuals than in neurotypical individuals in Arizona but not in Colorado. Gut microbiome composition was significantly associated with ASD while controlling for study-site location but not when controlling for gastrointestinal symptoms. This suggests that non-ASD-related study site differences in gut microbiome composition and different degrees of gastrointestinal symptoms involvement with ASD between sites may contribute to inconsistent results in the literature regarding the association between gut microbiome composition and ASD. In the longitudinal analysis, we found that difference in levels of lethargy/social withdrawal measured in individuals at different time points correlated with the degree of change in gut microbiome composition and that a worsening of inappropriate speech between time points was associated with decreased gut microbiome diversity. This relationship between changes in the gut microbiome composition within individuals and ASD behavioral severity metrics indicates that longitudinal study designs may be useful for exploring microbial drivers of ASD severity when substantial variability exists in baseline microbiome compositions across individuals and geographical regions.<b>IMPORTANCE</b> Autism spectrum disorder (ASD) is a brain developmental disorder with varying behavioral symptom severity both across individuals and within individuals over time. There have been promising but also inconsistent literature results regarding how the gut microbiota (microbiome) may be involved. We found that the gut microbiome in individuals with ASD is affected by study-site location as well as gastrointestinal symptom severity. When we sampled some individuals with ASD at several different time points, we found that some behaviors, such as lethargy/social withdrawal and inappropriate speech, changed along with changes in the gut microbiota composition. This is the first study to relate severity of behavior symptoms to gut microbiome composition within individuals over time and suggests a dynamic relationship between ASD-associated symptoms and gut microbes. Longitudinal study designs as well as collaborative efforts across multiple centers are needed to fully characterize the relationship between ASD and gut microbes.
