Successive encryption and transmission with phase-shifting digital holography (2006)

We present a novel information or key encryption and transmission technique based on phase-shifting digital holography for a security system. Phase-shifting digital holography is used for recording phase and amplitude information on CCD device. 4-step phase-shifting is implemented by moving the PZT mirror with equidistant phase steps of &#960;/2. The information and the key are converted to random phase patterns. Digital hologram in this method is Fourier transform hologram and quantized with 256 gray-level. The basic idea is that we reuse a 256 gray-level digital hologram to encrypt the information or the key with 4-step phase-shifting digital holography. The encrypted binary data/image in the form of digital hologram can be transmitted through communication network, and is reconstructed and decrypted digitally. The simulation shows that the proposed method gives good results for a successive encryption/transmission.
The proportion of Th1 cells, which prevail in gut mucosa, is decreased in inflammatory bowel syndrome (2001)

T lymphocytes and their cytokines have an important role in the regulation of immune responses in the gut and in the pathogenesis of intestinal inflammation such as in Crohn's disease. The aim of this study was to analyse the Th1/Th2 cytokine profile (IFN-gamma, IL-2, IL-4 and IL-10) in intraepithelial lymphocytes (IEL) and lamina propria lymphocytes (LPL) in Crohn's disease (CD) and ulcerative colitis (UC) in relation to healthy controls (C). Colonic and ileal biopsy specimens were obtained from controls (n = 13) and patients with CD (n = 32). Colonic biopsies were obtained from patients with UC (n = 11). Intracytoplasmic IFN-gamma, IL-2, IL-4 and IL-10 were determined by flow cytometry after PMA-ionomycin stimulation in IEL and LPL. In colonic LPL, a significant proportional decrease of IFN-gamma and IL-2 producing CD3+ cells was observed in patients with CD and UC compared to controls. In ileal LPL, a similar tendency was found although differences were not significant. In IEL no differences in cytokine profiles could be observed. Flow cytometric analysis of intracytoplasmic cytokines at single cell level showed a proportional decrease of IFN-gamma and IL-2 producing T cells in colonic lamina propria in patients with inflammatory bowel disease.

Theoretical Energy Density of Li–Air Batteries (2008)

A model for predication of the gravimetric and volumetric energy densities of Li-air batteries using aqueous electrolytes is developed. The theoretical gravimetric/volumetric capacities and energy densities are calculated based on the minimum weight of the electrolyte and volume of air electrode needed for completion of the electrochemical reaction with Li metal as an anode electrode. It was determined that both theoretical gravimetric/volumetric capacities and energy densities are dependent on the porosity of the air electrode. For instance, at a porosity of 70%, the maximum theoretical cell capacities are and in basic electrolyte, and and in acidic electrolyte. The maximum theoretical cell energy densities are and in basic electrolyte, and and in acidic electrolyte. The significant deduction of cell capacity from specific capacity of Li metal is due to the bulky weight requirement from the electrolyte and air electrode materials. In contrast, the Li-air battery using a nonaqueous electrolyte does not consume electrolyte during the discharge process and has high cell energy density. For Li-air batteries using both aqueous and nonaqueous electrolytes, the weight increases by 8–13% and the volume decreases by 8–20% after the cell is fully discharged.
Comparative Analysis of Docking Motifs in MAP-Kinases and Nuclear Receptors (2003)

Nuclear receptor (NR) agonists induce activation of mitogen-activated protein kinases (MAPK) through an yet unknown rapid non-genomic mechanism. Vice versa, NR are targets for phosphorylation by MAPK. By multiple alignment of the amino acid sequences and comparative analysis of the secondary and tertiary structures we identified four peptides in MAPK with similarity to bona fide protein-protein-interaction motifs in NR. In both molecule species, these motifs mediate selective docking to dimerization partners, coregulators or phosphoacceptors. We therefore propose that similar motifs may direct the site-specific association of NR with MAPK. Based on mutual allosteric interactions within a kinase-receptor complex, we discuss a novel principle how NR-agonists may regulate kinase activity and thus expression of hormone-dependent genes.
Building virtual networks across multiple domains (2011)

This paper presents a platform for virtual network (VN) provisioning across multiple domains. The platform decomposes VN provisioning into multiple steps to address the implications of limited information disclosure on resource discovery and allocation. A new VN embedding algorithm with simultaneous node and link mapping allows to assign resources within each domain. For inter-domain virtual link setup, we design and realize a signaling protocol that also integrates resource reservations for providing virtual links with Quality-of-Service guarantees. Experimental results show that small VNs can be provisioned within a few seconds.
3-D image reconstruction of brain vessels from angiograms (2002)

This paper presents a reconstruction process to build the three-dimensional cerebral vessel tree from a pair of DSAs (digital subtraction angiograms). To segment the blood vessels from the background, the local thresholding and global thresholding was used to bilevel the input image. Thinning is applied to obtain the skeleton of the vessels. The B-spline curve is used to smooth the skeleton. The skeleton is then tracked to find the branch points of the skeleton and used as the feature points for matching. The radius of the vessel was detected by the matched filter concept. For each feature point in the first image, we use the epipolar constraint and the property of feature points to find its correspondence on the other image. From the DSA machine structure, the data provided by the machine and the correspondence information, the least squares estimate of the real 3D skeleton position is obtained. By using the Gouraud shading method and the radius information, we display the reconstructed 3D shading images for various viewing angles and light source directions.

The noninvasive pH sensor facilitated the detection of most strains of bacterial contaminants within 3 days with no potential for sampling error.
Fast Sparse Matrix-Vector Multiplication on GPUs: Implications for Graph Mining (2011)

Scaling up the sparse matrix-vector multiplication kernel on modern Graphics Processing Units (GPU) has been at the heart of numerous studies in both academia and industry. In this article we present a novel non-parametric, self-tunable, approach to data representation for computing this kernel, particularly targeting sparse matrices representing power-law graphs. Using real data, we show how our representation scheme, coupled with a novel tiling algorithm, can yield significant benefits over the current state of the art GPU efforts on a number of core data mining algorithms such as PageRank, HITS and Random Walk with Restart.

dHSS - distributed Peer-to-Peer implementation of the LTE HSS based on the bitcoin/namecoin architecture (2016)

The Home Subscriber Server (HSS) within the packet core of the Long Term Evolution (LTE) is a key node leveraged for essential operations, such as mutual authentication and access control. This centralized node is essential for the overall network operation as it is the cornerstone of the cryptographic functions executed in a mobile network. It stores several parameters for each subscriber, including a copy of the secret key ki that is securely stored in the Subscriber Identity Module (SIM). The advent of the Internet of Things (IoT) has sparked the concern in the industry on the potential risk of control plane signaling overloads. Due to the traffic characteristics of IoT devices and the potential risk of malfunctioning or compromised devices, there is a potential risk for floods of signaling traffic overwhelming the mobile core network and, in particular, the HSS. Moreover, recent security research has theorized potential attacks against this central core network node that could be launched from a botnet of compromised smartphones. In this paper we theoretically introduce a novel distributed and secure Peer-to-Peer (P2P) implementation of the HSS. Based on the Bitcoin/Namecoin framework, this new architecture drifts away from the symmetric key model of the standard HSS and proposes a robust public key infrastructure. Moreover, it does not rely in central points of failure, it is resilient to signaling overload threats and allows to re-authenticate and re-generate mobile session keys frequently with zero control plane signaling load at the mobile core.
Supporting workflow in a course management system (2005)

CMS is a secure and scalable web-based course management system developed by the Cornell University Computer Science Department. The system was designed to simplify, streamline, and automate many aspects of the workflow associated with running a large course, such as course creation, importing students, management of student workgroups, online submission of assignments, assignment of graders, grading, handling regrade requests, and preparation of final grades. In contrast, other course management systems of which we are aware provide only specialized solutions for specific components, such as grading. CMS is increasingly widely used for course management at Cornell University. In this paper we articulate the principles we followed in designing the system and describe the features that users found most useful.

Tele-presence information and remote-controlled task execution (2002)

We developed a remote-controlled system which enabled us to effectively control remote construction machinery such as a backhoe shovel, wheel dump and bulldozer using video images at a safe distance and in a comfortable environment. We used this system for one year at Mt. Fugen, an active volcano in Shimabara City of Nagasaki Prefecture, which is known for the disaster in which a large scale pyroclastic eruption killed many people.
Two-layer hierarchical coding for MPEG-2 video (2000)

A two-layer scheme for MPEG-2 video that uses adaptive data-partitioning (ADP) is presented. The slice structure of the upper layer and a new synchronisation procedure between the layers are defined. The experimental results prove the effectiveness of the two-layer model, particularly for increasing values of cell loss probability.
Galvanic Skin Reflex and Plasma Free Fatty Acids During Insulin Reactions (1964)

Hypoglycemic reactions, induced by insulin (0.2 U./kg. intravenously), were studied in sixteen diabetic and twelve nondiabetic control subjects. The course of the reaction was monitored by continuous recording of the galvanic skin reflex (GSR) and by determination of the levels of blood glucose and free fatty acids (FFA) at 10, 20, 30, 60 and 120 minutes. Symptoms of reaction appeared in all of the controls at 32 ± 12 minutes after the insulin at a mean blood glucose level of 22 ± 7 mg. per 100 ml., and in the eleven of the diabetics at 70 ± 30 minutes and at a mean glucose level of 280 ± 192 mg. per 100 ml. Onset of the insulin reaction was documented by a sudden drop in GSR which corresponded with the onset of symptoms. The GSR fell to a mean of 75 per cent of the baseline value and returned to the baseline thirty minutes later. All of the controls and nine of the diabetics showed the GSR response. The GSR correlates well with symptoms of insulin reactions. Evidence of insulin reaction occurring in nine diabetic patients at high blood glucose levels is documented by GSR response. Free fatty acids (FFA) in the plasma showed a more rapid return to baseline values in those subjects manifesting the quicker GSR response. The change in the GSR is a more sensitive though less specific measure of the homeostatic response to insulin than the change in the FFA.
Biological reactions of alveolar bone to orthodontic loading of oral implants (2001)

Enosseous oral implants have been suggested as anchorage for orthodontic appliances in cases where the existing dentition cannot provide sufficient stability. Long-term studies of oral implants have suggested that excessive loading may contribute as an etiologic factor in the pathogenesis of failing implants. The purpose of the present study was to perform a histomorphometric analysis of tissue reactions around implants subjected to a well-defined force system. The analysis was performed on undecalcified sections cut perpendicularly to the long axis of the implant. The degree of osseointegration, bone density at varying distances from the implant as well as the relative extent of resorption and formation of alveolar bone adjacent to the implant-bone interface were evaluated. The results were correlated with the local strain of the tissue estimated by the means of a finite element analysis. It was found that loading significantly influenced both the turnover and the density of the alveolar bone in the proximity of the implants. However, even unloaded implants tended to maintain the bone characteristics of the alveolar process. On the other hand, the degree of osseointegration appeared to be independent of the loading of the implant.
Parents’ Experiences and Responses to an Intervention for Psychological Preparation of Children and Families During the Child’s Radiotherapy (2017)

The aim of this study was to evaluate parents' experiences and responses to a systematic intervention for psychological preparation of children and families during the child's radiotherapy (RT) treatment. In this case-control study at 3 pediatric RT centers, an intervention with a preparatory kit, including age-adjusted information on tablets, gift of a stuffed toy or a pair of headphones, a parent booklet, and toy models of the computed tomography and RT machines was implemented. For evaluation, a mixed methods data collection was conducted. A total of 113 parents of children undergoing RT were included-n = 59 in the baseline group and n = 54 in the intervention group. Health-related quality of life was rated low, but parents in the intervention group expressed less anxiety after the RT compared with the baseline group. They found information suitable for their young children, siblings, and friends were involved and the toy models were used for play. Parents expressed positive feelings due to close interaction with staff and each other within the family. The solutions developed within a human-centered design approach and shaped as a systematic family-centered strategy contributed to parents understanding and coping with the child's RT.
Differential sensitivity of HELA cells to the type 2 ribosome-inactivating proteins ebulin l, nigrin b and nigrin f as compared with ricin. (1996)

The new type 2 RIPs ebulin l, nigrin b and nigrin f present in Sambucus display toxicity to HELA cells several orders of magnitude lower than that displayed by ricin. Despite N-terminal amino acid homology between the three RIPs in both the A and the B chains, these compounds display very different degrees of toxicity to HELA cells that does not seem to be paralleled by immunologic correlations. It is suggested that small changes in the protein structure are most probably responsible for the different degrees of toxicity.
Percutaneous Valve Insertion for the Treatment of Calcific Aortic Valve Stenosis (2005)

In acquired aortic valve stenosis, aortic valve replacement (AVR) is the treatment of choice, offering symptomatic relief and improving long-term survival of patients. Whereas the rate of operative mortality ranges from 3% to 8% in the majority of cases (1–3), the operative risk is much higher in patients with emergency operation, very old age, advanced NYHA functional classification, associated coronary bypass surgery, or severe left ventricular dysfunction (4–8). However, even in these complicated settings, surgery is known to improve survival over no intervention (9–12). Prolonged life expectancy has resulted in an aging population and, consequently, in an increased number of patients requiring AVR. Balloon aortic valvuloplasty (BAV), introduced in 1986 (13), has been shown to provide a temporary improvement of valvular function and relief of symptoms in patients in whom surgery is considered too high risk or contraindicated (14–19). As a palliative treatment, its use is currently limited to patients who are declined for AVR because of poor clinical condition or severe comorbidities, mainly elderly patients. Given the limited therapeutic options in this subset of patients, there has been interest in the development of a percutaneous delivered aortic valve.

Paraquat for Weed Control Prior to Establishing Legumes (1969)

Land was prepared conventionally in early spring for the planting of small seeded legumes. Planting was delayed to allow emergence of weeds. We applied 1,1'-dimethyl-4,4'-bipyridinium salts (paraquat) and planted legumes immediately afterwards. Stage of weed growth, time of herbicide application, rate of chemical applied, and the methods of seeding were variables imposed. Paraquat (plus surfactant) applied at 1.1 and 2.2 kg/ha to emerged weeds prior to the seeding of legumes controlled quackgrass [ Agropyron repens (L.) Beauv.] sufficiently to allow excellent establishment of alfalfa ( Medicago sativa L.) and birdsfoot trefoil ( Lotus corniculatus L.). A paraquat application delayed until yellow nutsedge ( Cyperus esculentus L.) was at least 10 cm in height, followed by a disking, controlled the sedge sufficiently to allow legume establishment. For annual weed control, 0.3% kg/ha of paraquat was sufficient. Drilling as a method of seeding gave better legume stands than did surface-seeding techniques.
POD-Based Recursive Temperature Estimation for MR-Guided RF Hyperthermia Cancer Treatment: A Pilot Study (2018)

In this paper, proper-orthogonal-decomposition (POD) reduced models of the body's heat response to radio-frequency hyperthermia cancer treatment are used for recursive temperature estimation. First, efficient low-dimensional models are obtained by projecting high-resolution finite-difference discretized models on low-dimensional subspaces spanned by empirical simulation modes. These models are then used in a Kalman filter to obtain recursive 3D temperature estimates from noise-susceptible magnetic resonance thermometry (MRT). The strategy is tested on an experimental setup containing an anthropomorphic phantom. It is found that recursive estimation reduces the mean absolute temperature error for the phantom experiment by 38% when compared to MRT and may be a valuable addition to MRT, most notably in the case where high quality thermometry is temporally interleaved with thermometry of degraded quality.
Stability of nitroglycerin injection determined by gas chromatography (1978)

The stability of nitroglycerin injection was studied over an eight-week period. Gas-liquid chromatographic assay and thin-layer chromatography were used to study the stability in relation to sorption by rubber and plastic (Viaflex), light and the effect of two diluents (5% dextrose in water and 0.9% sodium chloride for injection). More nitroglycerin was lost from vials with rubber closures, and the loss occurred at a faster rate when compared with nitroglycerin packaged in ampuls. There was no difference in the loss of nitroglycerin from injection packaged in ampuls when stored in the light or in the dark, or in the loss of nitroglycerin from two diluents, 5% dextrose in water and 0.9% sodium chloride for injection, packaged in glass bottles. A 70.4% greater loss of nitroglycerin occurred from Viaflex bags than from glass bottles. Loss of nitroglycerin in this study may have been characterized by reversible first-order kinetics.
Ion-irradiation control of photoluminescence from porous silicon (1991)

Ion irradiation was used to pattern a region of red-light emitting porous silicon by eliminating visible-light photoluminescence (PL). The PL peak wavelength is approximately 735 nm and shows little dependence on the excitation-light wavelength. The ratio of PL intensities for different excitation wavelengths was shown to be proportional to the ratio of the absorption coefficients. Below saturation, the integrated PL intensity increased linearly with excitation-light power density.
