Is haptic watermarking worth it? (2006)

Usage of 3D data and models is receiving a growing interest for several applications, like training, museum displays, multimodal interfaces, aid for impaired people. In such a framework the need will soon raise to protect 3D data from misuse. Among the technologies that can be used to this aim, digital watermarking has a prominent role, due to its versatility and non-obtrusiveness. A basic requirement of any watermarking scheme is that the embedded code is invisible, or non-perceivable, by the end user of the data. This requirement also holds for 3D objects, it is then necessary that the human ability of perceiving a signal hidden in a 3D object is studied. In this paper we present a preliminary analysis aiming at comparing the perceptibility of the hidden signal when the 3D model is sensed through different senses, namely vision (through common rendering techniques and subsequent display on a monitor) and touch (through a haptic interface). Specifically our investigation aimed at assessing whether ensuring watermark invisibility is sufficient to ensure that the watermark presence can not be felt haptically. The answer stemming from our preliminary analysis seems to be a clear no, even if further studies will be necessary before a definitive answer can be given.
A protocol conversion software toolkit (1989)

This paper describes a “toolkit” (a software function library) for synthesizing conversions between different transport interfaces. The method employed involves classifying these interfaces according to their “transport abstraction type.” Each actual interface is converted to or from a canonical form depending on its type, and the library also contains sufficient “abstraction converters” to convert between all of the canonical forms. The overall conversion is accomplished by combining some number of elementary conversions which execute in series. The paper describes the toolkit, contrasts it with other approaches, and shows how it can be used to solve various problems in protocol conversion and the “migration” of distributed services to new network contexts.
Improving pairwise learning to rank algorithms for document retrieval (2017)

Learning to rank has recently emerged as an attractive technique dedicated to the optimization of results rankings and based on machine learning techniques. Several search engine applications are using this technique to train their ranking model. Theoretically, the problem of ranking is to predict an ordering over a set of pairs query-document. However, the enormously large size of the Web documents makes it generally impossible for the users to find their desired information by surfing the Web. As a consequence, effective and efficient information retrieval (IR) has become more important and also IR system (IRS) has become indispensable tool that can allow the user to access only to the information he deems relevant. Currently, we have proposed two pairwise learning to rank algorithms which combine active and semi-supervised learning to reduce the labeling effort for DR. In this paper, we propose to improve these semi-supervised active algorithms by using a list of pairs in selecting unlabeled data. We showed through different ranking measures that the algorithms proposed yielded into competitive results compared to SAL2R and ASSL2R on collections from the standard benchmark Letor.
Fixed-Hamming-Weight Representation for Indistinguishable Addition Formulae (2006)

In the execution of signature on a smart card, side channel attacks such as simple power analysis (SPA) have become serious threat12). There are the fixed procedure method and the indistinguishable method for SPA resistant methods. The indistinguishable method conceals all branch instructions by using indistinguishable addition formulae but may reveal the hamming-weight when an addition chain with the un-fixed-hamming-weight is used. In the case of hyper-elliptic curve, the indistinguishable method has not been proposed yet. In this paper, we give an indistinguishable addition formulae of hyper-elliptic curve. We also give algorithms which output the fixed-hamming-weight representation for indistinguishable addition formulae and works with or without computation table, which can dissolve the above mentioned problem on the indistinguishable method and are also applied to an elliptic curve scalar multiplication.
Communication System Simulation and Analysis with SYSTID (1984)

The design of satellite and deep space communications systems frequently involves problems that cannot be solved through pure analysis. In these cases simulation is an invaluable system design tool. This paper describes a flexible communication system simulation package, SYSTID, which has been under continual development and use at Hughes Space and Communications Group for over 15 years. We discuss the history of SYSTID's development as well as its internal workings. Both the software structure and analytic techniques are described. The paper includes several examples, one of which demonstrates SYSTID's topological input language. Hardware comparisons which show the accuracy and limitations of the simulation approach are also presented.
Automatic detection and correction for glossy reflections in digital photograph (2010)

The popularization of digital technology has made shooting digital photos and using related applications a part of daily life. However, the use of flash, to compensate for low atmospheric lighting, often leads to overexposure or glossy reflections. This study proposes an auto-detection and inpainting technique to correct overexposed faces in digital photography. This algorithm segments the skin color in the photo as well as uses face detection and capturing to determine candidate bright spots on the face. Based on the statistical analysis of color brightness and filtering, the bright spots are identified. Finally, bright spots are corrected through inpainting technology. From the experimental results, this study demonstrates the high accuracy and efficiency of the method.
Clonidine and Naltrexone (1982)

Clonidine hydrochloride and naltrexone hydrochloride, given in combination, were found to provide a safe, effective, and extremely rapid treatment of abrupt withdrawal from methadone hydrochloride therapy. Under controlled inpatient conditions established to assess dosage guidelines and to examine specific signs and symptoms of withdrawal, ten (91%) of 11 patients were able to withdraw completely from methadone therapy by the end of a six-day period. Six days of clonidine hydrochloride treatment, with a peak mean dose of 2.9 mg/day on treatment day 2, attenuated the withdrawal-inducing effects of naltrexone. Naltrexone hydrochloride was gradually increased from an initial 1-mg dose on treatment day 2 to 50-mg maintenance dose on treatment day 5 without an associated increase in withdrawal symptoms. Clonidine significantly decreased BP without producing clinical problems. The withdrawal symptoms of anxiety, restlessness, and muscular aching were most resistant to treatment, but at discharge most patients were completely asymptomatic.
Fast Planning in Stochastic Games (2013)

Stochastic games generalize Markov decision processes (MDPs) to a multiagent setting by allowing the state transitions to depend jointly on all player actions, and having rewards determined by multiplayer matrix games at each state. We consider the problem of computing Nash equilibria in stochastic games, the analogue of planning in MDPs. We begin by providing a generalization of finite-horizon value iteration that computes a Nash strategy for each player in generalsum stochastic games. The algorithm takes an arbitrary Nash selection function as input, which allows the translation of local choices between multiple Nash equilibria into the selection of a single global Nash equilibrium. Our main technical result is an algorithm for computing near-Nash equilibria in large or infinite state spaces. This algorithm builds on our finite-horizon value iteration algorithm, and adapts the sparse sampling methods of Kearns, Mansour and Ng (1999) to stochastic games. We conclude by descrbing a counterexample showing that infinite-horizon discounted value iteration, which was shown by shaplely to converge in the zero-sum case (a result we give extend slightly here), does not converge in the general-sum case.
Identification of sporadic mutations in the helix initiation motif of keratin 6 in two pachyonychia congenita patients: further evidence for a mutational hot spot (1999)

Pachyonychia congenita (PC) is a rare, autosomal dominant, ectodermal dysplasia characterized most distinctly by the presence of symmetric nail hypertrophy. In the Jadassohn-Lewandowsky form, or PC-1, additional cutaneous manifestations may include palmoplantar hyperkeratosis, hyperhidrosis, follicular keratoses, and oral leukokeratosis. Mutations have previously been identified in the 1A helix initiation motif of either keratin 6 or keratin 16 in patients with PC-1. In the current study, we have identified 2 sporadic, heterozygous mutations in the 1A helix region of the K6 isoform (K6a). The first mutation identified was a 3 base pair deletion (K6adelta N171). The second mutation was a C-to-A transversion resulting in an amino acid substitution (K6a N171K). These data, in combination with previous reports, provide further evidence that this location is a mutational hot spot.
Corpus Analysis for TREC 5 Query Expansion. (1996)

Accessing online information remains an inexact science. While valuable information can be found, typically many irrelevant documents are also retrieved and many relevant ones are missed. Terminology mismatches between the user&apos;s query and document contents is a main cause of retrieval failures. Expanding a user&apos;s query with related words can improve search performance, but the problem of identifying related words remains. This research uses corpus linguistics techniques to automatically discover word similarities directly from the contents of the untagged TREC database and to incorporates that information in the SMART information retrieval system. The similarities are calculated based on the contexts in which a set of target words appear. Using these similarities, user queries are automatically expanded, resulting in conceptual retrieval rather than requiring exact word matches between queries and documents. 1. INTRODUCTION Expanding a user&apos;s query with related terms can improve sea...

Molecular Stress Relief through a Force-Induced Irreversible Extension in Polymer Contour Length (2010)

Single-molecule force spectroscopy is used to observe the irreversible extension of a gem-dibromocyclopropane (gDBC)-functionalized polybutadiene under tension, a process akin to polymer necking at a single-molecule level. The extension of close to 28% in the contour length of the polymer backbone occurs at roughly 1.2 nN (tip velocity of 3 μm/s) and is attributed to the force-induced isomerization of the gDBCs into 2,3-dibromoalkenes. The rearrangement represents a possible new mechanism for localized stress relief in polymers and polymer networks under load, and the quantification of the force dependency provides a benchmark value for further studies of mechanically triggered chemistry in bulk polymers.

Anaerobic fermentation: alcohol production (1980)

Abstract Anaerobic fermentation of carbohydrates by yeasts and bacteria leads to the production of a range of alcohols, acids and esters. Three alcohols, ethanol, isopropanol and butanol, are currently made industrially by fermentation, though, in most places, production from petroleum is cheaper than the biological conversion. The conversion of glucose to ethanol can be achieved at approaching the theoretical maximum efficiency of 51% (by mass) based on the biochemical route, retaining 93% of the energy content of the carbohydrate. However, the cost of carbohydrate feedstock and the processing cost are generally high compared with the value of the alcohol. The costs and energy balances for alcohol production from a range of feedstocks are discussed. Technological improvements, particularly in reduction of capital and energy requirements, could substantially reduce the processing costs. Developments can be expected in (i) the application of continuous fermentation and immobilized cells; (ii) the development of organisms with increased tolerance to alcohols, wider substrate ranges and higher temperature optima; and (iii) lower energy requirements for recovery of alcohols. Given reasonable technical progress, the wider adoption of bioconversion of carbohydrates to alcohols and similar bulk chemicals will depend on the relative costs of carbohydrate to fossil hydrocarbons. In some regions of high agricultural productivity, and without petroleum, bioconversion processes are already in use and it seems likely that this trend will become more widespread over the next few decades.
Colloidal shuttles for programmable cargo transport (2017)

The active transport of cargo molecules within cells is essential for life. Developing synthetic strategies for cargo control in living or inanimate thermal systems could lead to powerful tools to manipulate chemical gradients at the microscale and thus drive processes out of equilibrium to realize work. Here we demonstrate a colloidal analog of the complex biological shuttles responsible for molecular trafficking in cells. Our colloidal shuttles consist of magneto-dielectric particles that are loaded with cargo particles or living cells through size-selective dielectrophoretic trapping using electrical fields. The loaded colloidal shuttle can be transported with magnetic field gradients before cargo is released at the target location by switching off the electrical field. Such spatiotemporal control over the distribution of chemically active cargo in a reversible fashion can be potentially exploited for fundamental biological research or for the development of novel technologies for advanced cell culturing, drug discovery and medical diagnosis.
Re-Imagining Outdoor Playspaces: An Unexpected Consequence of the COVID-19 Lockdown (2022)

This paper presents a series of reflective observations on the use of outdoor spaces in Melbourne, Australia, during the 2020 COVID-19 pandemic lockdown. With the closure of playgrounds and organized sports, the authors observed three themes emerging: changes in users and uses of parks and reserves; markers of children's activities in public areas; and, children's creation of huts, dens or "cubbies" as evidence of constructive and imaginative play. Using a small-scale autoethnographic methodology through individual random observations, journaling and photography, the authors found clear indications of a new, deeper connection to public and natural spaces across generations and within each of their separate "lockdown" communities. A more visible presence of children and play activity in each authors' local natural spaces suggests that these places are a source of wellbeing and resilience in challenging times.
Alteration of Rumen Fermentation, Milk Fat Synthesis, and Nutrient Utilization with Mineral Salts in Dairy Cows (1982)

The ability of mineral salts to alter rumen fermentation, rumen fluid dilution rate, milk fat synthesis, and nutrient utilization was investigated in dairy cows fed a high-concentrate, milk-fat depressing diet. Four rumen-fistulated Holstein cows were in a 4 X 4 Latin square design. Treatments consisted of: 1) basal (25% corn silage: 75% concentrate on a dry matter basis), 2) basal + 2.0% sodium chloride, 3) basal + 2.0% sodium bicarbonate, and 4) basal + 2.4% limestone. Addition of limestone to the basal diet reduced dry matter intake but increased efficiency of dietary nutrient utilization for milk synthesis. Sodium bicarbonate increased synthesis of milk fat. Sodium chloride also tended to increase milk fat synthesis whereas limestone had no effect. Milk yields (kg/day) and milk fat (%) for the four treatments were 1) 29.5, 2.40; 2) 29.3, 2.66; 3) 28.9, 3.26; and 4) 29.2, 2.32. Rumen fluid pH, dilution rate (%/hour), and molar percentage of acetate and propionate were: 1) 5.98, 10.3, 49 and 39; 2) 6.02, 12.4, 55 and 32; 3) 6.16, 12.2, 58 and 25; and 4) 5.92, 10.7, 51 and 38. Limestone was totally ineffective in altering ruminal pH, fluid dilution rate, molar percentages of acetate and propionate, and synthesis of milk fat. Improved feed efficiency for milk production after addition of limestone was related to an increase in starch digestion compared to the basal ration (95 versus 88%).
OST alpha-OST beta: a key membrane transporter of bile acids and conjugated steroids (2009)

The organic solute and steroid transporter, Ost alpha-Ost beta, is an unusual heteromeric carrier that appears to play a central role in the transport of bile acids, conjugated steroids, and structurally-related molecules across the basolateral membrane of many epithelial cells. The transporter's substrate specificity, transport mechanism, tissue distribution, subcellular localization, transcriptional regulation, as well as the phenotype of the recently characterized Ost alpha-deficient mice all strongly support this model. In particular, the Ost alpha-deficient mice display a marked defect in intestinal bile acid and conjugated steroid absorption; a decrease in bile acid pool size and serum bile acid levels; altered intestinal, hepatic and renal disposition of known substrates of the transporter; and altered serum triglyceride, cholesterol, and glucose levels. Collectively, the data indicate that Ost alpha-Ost beta is essential for bile acid and sterol disposition, and suggest that the carrier may be involved in human conditions related to imbalances in bile acid or lipid homeostasis.
Quantitative abdominal fat estimation using MRI (2008)

This paper introduces a new method for automatic quantification of subcutaneous, visceral and non-visceral internal fat from MR-images acquired using the two point Dixon technique in the abdominal region. The method includes (1) a three dimensional phase unwrapping to provide water and fat images, (2) an image intensity inhomogeneity correction, and (3) a morphon based registration and segmentation of the tissue. This is followed by an integration of the corrected fat images within the different fat compartments that avoids the partial volume effects associated with traditional fat segmentation methods. The method was tested on 18 subjects before and after a period of fast-food hyper-alimentation showing high stability and performance in all analysis steps.
Apolipoprotein E, Amyloid, and Alzheimer Disease (2002)

Despite important inroads into the molecular pathology of Alzheimer disease, effective long-term treatment for the condition remains elusive. Among the many gene products that are recognized as factors in the disease is apolipoprotein ( (apoE). The risk that specific isoforms of apoE pose with regard to Alzheimer Disease clearly varies, and so the roles that apoE plays in the brain will be crucial to a full understanding of the disease and to efforts to develop effective therapies.
