Transmission and radar cross-section reduction by combining binary coding metasurface and frequency selective surface (2018)

A modified reflective metasurface, which is constructed by replacing the metal ground of the reflective coding metasurface with a bandpass frequency-selective surface, is proposed. The metasurface has transmission and reduction of radar cross-section characteristics. This allows the metasurface to overcome the drawbacks of conventional realizations, which use lossy materials. The modified metasurface provides high-efficiency transmission in the passband of a frequency-selective surface and broadband reduction of the radar cross section in the rejection band of the frequency-selective surface. Transmission of -0.24 dB was achieved at 4.6 GHz, as well as a -15 dB reduction of radar cross section from 8.5 to 13.5 GHz. This work provides advancements in metasurface applications.
DefGraspSim: Physics-Based Simulation of Grasp Outcomes for 3D Deformable Objects (2022)

Robotic grasping of 3D deformable objects (e.g., fruits/vegetables, internal organs, bottles/boxes) is critical for real-world applications such as food processing, robotic surgery, and household automation. However, developing grasp strategies for such objects is uniquely challenging. Unlike rigid objects, deformable objects have infinite degrees of freedom and require field quantities (e.g., deformation, stress) to fully define their state. As these quantities are not easily accessible in the real world, we propose studying interaction with deformable objects through physics-based simulation. As such, we simulate grasps on a wide range of 3D deformable objects using a GPU-based implementation of the corotational finite element method (FEM). To facilitate future research, we open-source our simulated dataset (34 objects, 1e5 Pa elasticity range, 6800 grasp evaluations, 1.1 M grasp measurements), as well as a code repository that allows researchers to run our full FEM-based grasp evaluation pipeline on arbitrary 3D object models of their choice. Finally, we demonstrate good correspondence between grasp outcomes on simulated objects and their real counterparts.

Quantized Hall resistance in large-scale monolayer graphene | NIST (2015)

Graphene is a one-atom-thick carbon lattice that can be exfoliated from solid graphite or grown using high temperature processing methods on a variety of substrates. Many practical applications of large-area graphene, however, are limited by the transport mobility and carrier concentration homogeneity over distances greater than hundreds of microns. This presentation reports on the characteristics of large area (5 mm 2 to 25 mm 2 ) monolayer devices that display precise quantum Hall effect (QHE) characteristics at reasonable cryogenic temperatures, surpassing the previously reported records for graphene.
How close are we to the temperature tipping point of the terrestrial biosphere? (2021)

The temperature dependence of global photosynthesis and respiration determine land carbon sink strength. While the land sink currently mitigates ~30% of anthropogenic carbon emissions, it is unclear whether this ecosystem service will persist and, more specifically, what hard temperature limits, if any, regulate carbon uptake. Here, we use the largest continuous carbon flux monitoring network to construct the first observationally derived temperature response curves for global land carbon uptake. We show that the mean temperature of the warmest quarter (3-month period) passed the thermal maximum for photosynthesis during the past decade. At higher temperatures, respiration rates continue to rise in contrast to sharply declining rates of photosynthesis. Under business-as-usual emissions, this divergence elicits a near halving of the land sink strength by as early as 2040.
Current Prospective of Aldose Reductase Inhibition in the Therapy of Allergic Airway Inflammation in Asthma (2011)

The prevalence of asthma and costs of its care have been continuously increasing, but novel therapeutic options to treat this inflammatory disease have not been brought to the US market. Current therapies such as inhaled steroids, long-acting beta-agonist bronchodilators, antihistamines and immunomodulators may control the symptoms of allergic asthma but fail to modify the underlying disease. Excessive use of steroids and other immunosuppresents alter the patient's quality of life, produce undesirable toxicities, and increase the risk of other pathologies such as diabetes. Hence novel therapeutic options to manage asthma are desirable. In the present review, we have discussed the role of the polyol pathway enzyme aldose reductase (AR) in the amplification of allergic airway inflammation. Recent studies have indicated that AR inhibition prevents the NF-κB-dependent generation of pro-inflammatory cytokines and chemokines in mouse models of allergic airway inflammation indicating the potential use of AR inhibition as a novel tool to control allergic responses. Since orally available AR inhibitors have already undergone phase III clinical trials for diabetic neuropathy and appear to have a manageable side effects profile, they could be readily developed as potential new drugs for the treatment of asthma and related complications.
A Comparative Study on Computational Two-Block Motif Detection: Algorithms and Applications (2007)

Since the completion of human genome sequencing, cataloging of all genomic functional elements has been one of the challenging problems in bioinformatics. Deciphering cis-regulatory elements in the human genome still remains elusive although much effort has been expended. This paper reviews a suite of methods for two-block motif discovery including mathematical modeling, de novo motif-finding based on multiple local alignment, and genomic sequence scanning method for putative sites. We formulate a general method to address this challenge and compare two major existing algorithms (i.e., greedy local search and Gibbs sampling) implemented to solve the popular two-block structured motif discovery issue. We demonstrate how to use this suite of methods and apply them to human nuclear receptor response elements (i.e., protein binding sites of several relevant nuclear receptors, HNF4alpha, CAR/RXR, and PXR/RXR).
Earthquake Damage to Industrial Facilities and Development of Seismic and Vibration Control Technology (2008)

This paper reviews the situations and features of earthquake damage to industrial facilities, manufacturing companies, energy supply facilities, and mechanical structures and installations in Japan, and traces trends of countermeasure technology developed focusing on earthquake resistance and vibration control. In Japan, with the 1964 Niigata earthquake as the turning point, earthquake damage to industrial facilities became a social problem. With power stations being constructed in the 1960s, it also became an important technological policy to establish seismic design method for nonbuilding structures such as equipment and piping systems related to nuclear power. The Kobe earthquake in 1995 damaged production companies including leading manufacturers so extensively that it brought a new focus to seismic considerations. We studied the damage to typical equipment and installations and, based on this experience, investigated the features of damage modes to industrial facilities and machinery and considered corresponding technical measures. We present some examples and discuss progressive trends in seismic and vibration control technology following the Kobe earthquake. In particular, we focus on the new seismic design code for high-pressure gas facilities and the development of seismic and vibration control dampers and their applications.
The effect of diets high in fat and/or fiber on colonic absorption of DMH in the rat (1986)

The possibility that long-term feeding of diets high in fat or fiber could alter the colonic mucosa and subsequent colonic absorption of 1,2-dimethylhydrazine (DMH) in situ was examined in the rat model. Male Sprague-Dawley rats were fed one of four experimental diets for six weeks prior to studies of DMH absorption and bile acid excretion; dietary treatments consisted of two levels of fat (12 and 47% of calories from corn oil) fed at each of two levels of fiber (plus or minus 15% wheat bran). Two sets of DMH absorption studies (Studies 1 and 2) were performed; the first used a 10- and the second a 20-minute test period. In Study 1, DMH absorption was greater in those animals that had been fed the high level of corn oil when additional fiber was not present in the diet. When a longer absorption period was used (Study 2), this effect of diet on DMH absorption was not apparent. The level of fiber, not the fat intake, altered bile acid excretion. Bile acid concentration (mg/g dry wt) decreased with added fiber, whereas total bile acid excretion (mg/day) increased. These results indicate that high levels of dietary fat may result in small increases in DMH absorption which are unrelated to changes in bile acid concentration.
The Missing Link - A Probabilistic Model of Document Content and Hypertext Connectivity (2000)

We describe a joint probabilistic model for modeling the contents and inter-connectivity of document collections such as sets of web pages or research paper archives. The model is based on a probabilistic factor decomposition and allows identifying principal topics of the collection as well as authoritative documents within those topics. Furthermore, the relationships between topics is mapped out in order to build a predictive model of link content. Among the many applications of this approach are information retrieval and search, topic identification, query disambigua-tion, focused web crawling, web authoring, and bibliometric analysis. 1

Multifocal pleomorphic dermal sarcoma and the role of inflammation and immunosuppression in a lung transplant patient: a case report (2019)

We hypothesize that chronic, multifocal inflammation in the skin in the setting of immunosuppression led to simultaneous, malignant transformation in numerous skin lesions. We discuss the challenges of diagnosing pleomorphic dermal sarcoma, therapeutic options, and stress the need for multidisciplinary management of these cases.
Effects Of Dual-tasking On Stability During Walking In Children With Cerebral Palsy (2015)

Background: Many children with Cerebral Palsy (CP) have impaired walking abilities associated with poor maintenance of balance. Such impairments unseen in typically developing children include reduced walking speed, reduced step length, and wider step width. Further, dual-tasking has been associated with reductions in walking speed, stride length, step width and toe clearance compared to normal walking in children with CP but not in typically developing children. However, little is known about the effects of dual-tasking on other balance characteristics during walking in this population. PURPOSE: To examine the effects of dual-tasking on stability (dynamic balance) during walking in children with CP. METHODS: Five assenting children with CP (four boys, one girl; 7.0 ± 0.9 yrs, 125.7 ± 6.5 cm, 26.0 ± 4.5 kg) participated in the experiment and walked four times across a 3.4 m GAITRite® instrumented walkway system (CIR Systems Inc., GAITRite, Sparta, NJ; 120 Hz) at their self-selected speed. Next, participants completed the same walking protocol while simultaneously carrying a tray, similar to what they might do in a school lunchroom. Foot pressure data were extracted and analyzed by footfall (minimum 12 strides per participant) to compare velocity, unilateral step width, stride width, and base of support width for each condition. Data were evaluated using a single-subject procedure (Model Statistic, α = 0.05). RESULTS: Walking velocity decreased significantly when dual tasking for two children (44.0 cm/sec and 40.7 cm/sec, respectively; p < 0.05) while two other children elicited a significant velocity increase (9.4 cm/sec and 12.5 cm/sec, respectively; p < 0.05). Three children reduced base of support when dual-tasking (2.9 ± 2.8 cm, 5.1 ± 4.2 cm, 7.6 ± 7.5 cm, respectively; p < 0.05). Stride width was reduced in two children as a result of the dual-tasking condition (3.7 ± 1.8 cm and 2.3 ± 3.2 cm, respectively; p < 0.05), and one of five children showed reduced step width (9.7 ± 5.1 cm; p < 0.05). CONCLUSION: This dual-tasking condition significantly altered dynamic balance characteristics in children with CP, most notably velocity, base of support, and stride width. Whether this was a function of the observed change in self-selected walking velocity or a characteristic of the population warrants further investigation.
SpaceWire Plug-and-Play: An Early Implementation and Lessons Learned (2007)

[Abstract] In the early days of SpaceWire, the authors built a demonstration SpaceWire network that could provide a level of fault-tolerance, through redundancy, unmatched by any other technology, yet with a performance some two orders of magnitude greater than previously offered. This was done with a Plug-and-Play system that could be assembled in an arbitrary fashion and continued to work by reconfiguring itself as faults were introduced and spare units brought on-line. The paper describes this demonstration network and the features we implemented to enable Plug-and-Play operation. We also evaluate the network’s features, some of which appear to work very well and others suggest further work is required. Most importantly, perhaps, is that we have learned what issues (or at least some of them) have to be considered in the design of such systems.
Temporal Trends of Cardiac Chambers Function with Trastuzumab in Human Epidermal Growth Factor Receptor II–Positive Breast Cancer Patients (2015)

The RV exhibited greater change in strain after trastuzumab treatment when compared to the LV. Atria function was reduced by trastuzumab as well. The repercussion of these findings and their potential implication will warrant further study.
Exceptionally-enhanced Q-factor sapphire-loaded-cavity TE/sub 01δ/ mode resonators (2003)

An innovative method of enhancing the quality factor of TE/sub 01/spl delta// cavity resonators with a dielectric tube made of monolithic sapphire is presented. Very high Q-factor is achieved by employing a Bragg reflection technique. A TE/sub 01/spl delta// mode in a copper cavity was measured to have a Q-factor of 1/spl times/10/sup 5/ at 8.78 GHz and 290 K. This is only 30% less than the limit due to the loss tangent of the dielectric material. The technique confines electromagnetic energy in the sapphire dielectric and in the vacuum well away from the cavity walls, thus reducing the surface losses in the copper shield. The technique offers some significant advantages over other methods. One advantage is the very low spurious mode density, which can improve filter and resonator design capabilities. Another is the small compact design, with a single sapphire piece, as compared to previously published Bragg reflection techniques. Finite element simulations and experimental data for this method were compared and found to be in very good agreement. The cavity dimensions were optimized to achieve maximum quality-factor.
Towards Protein Field‐Effect Transistors: Report and Model of a Prototype (2005)

A protein field-effect transistor (Pro-FET) based on the blue-copper protein azurins (see Figure) and operating at room temperature and ambient pressure is demonstrated. The transfer characteristics of the Pro-FET exhibit a pronounced resonance due to the switch from behaving as a n-metal oxide semiconductor FET (n-MOSFET) to a p-MOSFET. Carrier transport through the device is explained in terms of an equilibrium between the two possible oxidation states of the redox site (Cu1+ and Cu2+).
A Simple Single Step diffusion and Emitter Etching Process for High Efficiency Gallium Antimonide Thermophotovoltaic Devices (2003)

A single step diffusion followed by precise etching of the diffused layer has been developed to obtain a diffusion profile appropriate for high efficiency GaSb thermophotovoltaic cells. The junction depth was controlled through monitoring of light current-voltage (I-V) curves (photovoltaic response) during the post diffusion emitter etching process. The measured photoresponses (prior to device fabrication) have been correlated with the quantum efficiencies and the open circuit voltages in the fabricated devices. An optimum junction depth for obtaining highest quantum efficiency and open circuit voltage is presented based on diffusion lengths (or monitoring carrier lifetimes), carrier mobility and typical diffused impurity profile in GaSb.
A 100-MHz 51.2-Gb/s Packet Lookup Engine with Automatic Table Update Function (2017)

The development of an extremely efficient packet inspection algorithm for lookup engines is important in order to realize high throughput and to lower energy dissipation. In this paper, we propose a new lookup engine based on a combination of a mismatch detection circuit and a linked-list hash table. The engine has an automatic rule registration and deletion function; the results are that it is only necessary to input rules, and the various tables included in the circuits, such as the Mismatch Table, Index Table, and Rule Table, will be automatically configured using the embedded hardware. This function utilizes a match/mismatch assessment for normal packet inspection operations. An experimental chip was fabricated using 40-nm 8-metal CMOS process technology. The chip operates at a frequency of 100MHz under a power supply voltage of VDD =1.1V. A throughput of 100Mpacket/s (=51.2Gb/s) is obtained at an operating frequency of 100MHz, which is three times greater than the throughput of 33Mpacket/s obtained with a conventional lookup engine without a mismatch detection circuit. The measured energy dissipation was a 1.58pJ/b·Search.
Sensor Fusion for Augmented Reality (2006)

In augmented reality (AR), the position and orientation of the camera have to be estimated with high accuracy and low latency. This nonlinear estimation problem is studied in the present paper. The proposed solution makes use of measurements from inertial sensors and computer vision. These measurements are fused using a Kalman filtering framework, incorporating a rather detailed model for the dynamics of the camera. Experiments show that the resulting filter provides good estimates of the camera motion, even during fast movements
