Enabling Context-Aware Indoor Augmented Reality via Smartphone Sensing and Vision Tracking (2015)

Augmented reality (AR) aims to render the world that users see and overlay information that reflects the real physical dynamics. The digital view could be potentially projected near the Point-of-Interest (POI) in a way that makes the virtual view attached to the POI even when the camera moves. Achieving smooth support for movements is a subject of extensive studies. One of the key problems is where the augmented information should be added to the field of vision in real time. Existing solutions either leverage GPS location for rendering outdoor AR views (hundreds of kilometers away) or rely on image markers for small-scale presentation (only for the marker region). To realize AR applications under various scales and dynamics, we propose a suite of algorithms for fine-grained AR view tracking to improve the accuracy of attitude and displacement estimation, reduce the drift, eliminate the marker, and lower the computation cost. Instead of requiring extremely high, accurate, absolute locations, we propose multimodal solutions according to mobility levels without additional hardware requirement. Experimental results demonstrate significantly less error in projecting and tracking the AR view. These results are expected to make users excited to explore their surroundings with enriched content.
Introduction: The Place of Race in the 60s Phenomenon (2008)

Although historians and social commentators argue about the meaning of the '60s', none deny that dramatic and irreversible changes took place somewhere from the late 1950s through to the mid 1970s. 'The 1960s seem like another country,' wrote Dennis Altman in 1988. Perceptions changed, expectations were raised and demands made that ultimately reoriented society. In Australia, as in the United States and Europe, power bases shifted when those who demanded greater autonomy resisted traditional authority.⁴ Young men rejected the call of war, young women refused to accept a life of domesticity and black and indigenous people demanded equality.
Reduced graphene oxide with a highly restored π-conjugated structure for inkjet printing and its use in all-carbon transistors (2013)

An inkjet-printed graphene film is of great importance for next-generation flexible, low cost and high performance electronic devices. However, due to the limitation of the inkjet printing process, the electrical conductivity of inkjet-printed graphene films is limited to ∼10 S·cm−1, and achieving a high conductivity of the printed graphene films remains a big challenge. Here, we develop a “weak oxidation-vigorous exfoliation” strategy to tailor graphene oxide (GO) for meeting all the requirements of highly conductive inkjet-printed graphene films, including a more intact carbon plane and suitable size. The π-conjugated structure of the resulting graphene has been restored to a high degree, and its printed films show an ultrahigh conductivity of ∼420 S·cm−1, which is tens of times higher than previously reported results, suggesting that, aside from developing a highly efficient reduction method, tuning the GO structure could be an alternative way to produce high quality graphene sheets. Using inkjet-printed graphene patterns as source/drain/gate electrodes, and semiconducting single-walled carbon nanotubes (SWCNTs) as channels, we fabricated an all-carbon field effect transistor which shows excellent performance (an on/off ratio of ∼104 and a mobility of ∼8 cm2·V−1·s−1) compared to previously reported CNT-based transistors, promising the use of nanocarbon materials, graphene and SWCNTs in printed electronics, especially where high performance and flexibility are needed.
Preliminary Evaluation of a Skin Conductance Meter for Detecting Hypoglycemia in Diabetic Patients (1982)

A portable device (the Diabalert), which measures the electrical conductivity of the skin surface and sounds an alarm at a preset conductivity, was evaluated as a possible detector of hypoglycemia-induced sweating in diabetic subjects. Insulin was infused intravenously into seven insulin-dependent diabetic subjects, and the course of the plasma glucose decline, hypoglycemic symptoms, and state of consciousness of the patients frequently monitored. In five patients sweating occurred with hypoglycemia, and the Diabalert alarm was activated at plasma glucose concentrations between 1.6 and 3.7 mmol/L. Three of these five diabetic patients were by then unaware of the alarm and would have failed to take corrective action to restore normoglycemia. Two further patients had virtually no symptoms despite marked biochemical hypoglycemia and the alarm was not triggered. Studies are needed in larger numbers of diabetic patients at home to fully assess the clinical usefulness of this device.
Typography in Media Historical Perspective (2016)

At first glance, a special issue on the subject of typography might seem an unusual choice for an academic journal dedicated to media history. After all, wouldn’t the study of typography be better suited to a publication on the history of art and graphic design, or perhaps the study of books? A quick glance through previous general issues of the Journal for Media History (Tijdschrift voor Mediageschiedenis, or TMG) reveals that the majority of the articles deal with traditional media such as film, television, photography and print media. But TMG also publishes special issues on a wide variety of topics, ranging from the monarchy to scandals to representations of nature. These special issues challenge the journal to explore its boundaries, both in terms of research and scope. It will be interesting to see just which boundaries this special issue on typography will be crossed.
Correction of cAMP-Stimulated Fluid Secretion in Cystic Fibrosis Airway Epithelia: Efficiency of Adenovirus-Mediated Gene Transfer <i>In Vitro</i> (1994)

Adenovirus vectors are a promising vehicle to deliver cystic fibrosis transmembrane conductance regulator (CFTR) cDNA to airway epithelia. However, the value of adenovirus vectors will depend on the efficiency with which the vector can correct the defective fluid transport that is though to underlie the pathogenesis of the disease. To address the efficiency of gene transfer, we applied adenovirus vectors expressing CFTR (Ad2/CFTR-1) or beta-galactosidase to the mucosal surface of primary cultures of airway epithelial cells grown as polarized epithelial monolayers on permeable filter supports. These conditions provide a model that reproduces the physiology of the airways in vivo. We found that after adding 1 moi Ad2/CFTR-1 to the mucosal surface, cAMP agonists stimulated fluid secretion that was within the range observed in epithelia from normal subjects. When we measured electrolyte transport, we found that as little as 0.1 moi partially restored cAMP-stimulated Cl- secretion, and at 10 moi Cl- secretion was in the normal range. A related vector encoding beta-galactosidase generated activity in approximately 20% of cells at an moi of 1 and 90% of cells at an moi of 10. These data suggest that Ad2/CFTR-1 is very efficient at restoring normal fluid and electrolyte transport to CF airway epithelia. Thus, they suggest that relatively low input doses could be used for gene transfer to CF airway epithelia.
Enabling structure-based drug design of Tyk2 through co-crystallization with a stabilizing aminoindazole inhibitor (2012)

Practical criteria for construct performance and prioritization, the optimization of purification protocols to enhance protein yields and stability, and use of high-throughput construct exploration enable structure determination methods early in the drug discovery process. Additionally, specific ligands stabilize Tyk2 protein and may thereby enable crystallization.
Role of regulatory T cells during virus infection (2013)

The host response to viruses includes multiple cell types that have regulatory function. Most information focuses on CD4(+) regulatory T cells that express the transcription factor Foxp3(+) (Tregs), which are the topic of this review. We explain how viruses through specific and non-specific means can trigger the response of thymus-derived natural Tregs as well as induce Tregs. The latter derive under appropriate stimulation conditions either from uncommitted precursors or from differentiated cells that convert to become Tregs. We describe instances where Tregs appear to limit the efficacy of antiviral protective immunity and other, perhaps more common, immune-mediated inflammatory conditions, where the Tregs function to limit the extent of tissue damage that occurs during a virus infection. We discuss the controversial roles that Tregs may play in the pathogenesis of human immunodeficiency and hepatitis C virus infections. The issue of plasticity is discussed, as this may result in Tregs losing their protective function when present in inflammatory environments. Finally, we mention approaches used to manipulate Treg numbers and function and assess their current value and likely future success to manage the outcome of virus infection, especially those that are responsible for chronic tissue damage.
Do utilization management controls for phototherapy increase the prescription of biologics? (2006)

The use of phototherapy for psoriasis has declined because of inconvenience, managed care disincentives, and poor reimbursements. However, phototherapy is safer than other options, and the efficacy rates for different methods of phototherapy are among the highest of all available treatment options. Phototherapy is also one of the least costly treatments for moderate-to-severe psoriasis. We hypothesize that utilization management controls on phototherapy shift patients to more expensive and risky systemic treatments. Reducing disincentives on phototherapy will benefit both patients and payors, while increasing physicians' ability to manage this debilitating disease.
Fluorescent Isoindole Crosslink (FlICk) Chemistry: A Rapid, User‐friendly Stapling Reaction (2019)

Abstract The stabilization of peptide secondary structure via stapling is a ubiquitous goal for creating new probes, imaging agents, and drugs. Inspired by indole‐derived crosslinks found in natural peptide toxins, we employed ortho ‐phthalaldehydes to create isoindole staples, thus transforming inactive linear and monocyclic precursors into bioactive monocyclic and bicyclic products. Mild, metal‐free conditions give an array of macrocyclic α‐melanocyte‐stimulating hormone (α‐MSH) derivatives, of which several isoindole‐stapled α‐MSH analogues ( K i ≈1 n m ) are found to be as potent as α‐MSH. Analogously, late‐stage intra‐annular isoindole stapling furnished a bicyclic peptide mimic of α‐amanitin that is cytotoxic to CHO cells (IC 50 =70 μ m ). Given its user‐friendliness, we have termed this approach FlICk (fluorescent isoindole crosslink) chemistry.
Measurement of short and ultrashort <i>T</i><sub>2</sub> components using progressive binomial RF saturation (2006)

A new magnetic resonance (MR) method for measuring T2 relaxation times in tissues is proposed. The method is based on a T2 selective saturation period followed by sampling of the remaining longitudinal magnetization. Saturation of the longitudinal magnetization is accomplished by a single binomial RF pulse of zeroth order with a constant flip angle. The T2 selectivity is controlled by the RF pulse duration. A full T2 spectrum can be obtained by performing a series of measurements with varying RF pulse duration. On a conventional 1.5 T system this approach allows detection of T2 components as short as several hundred microseconds. A major limitation is the method's susceptibility to resonance offsets. At typical offsets of 0.1-0.2 ppm the sensitivity of the method is limited to a T2 range below 20 ms, which corresponds to an RF pulse duration shorter than 50 ms. The new method was used to acquire T2 spectra from the liver of pigs in vitro on a conventional 1.5 T system. We observed a short T2 component around 17 ms and an ultrashort T2 component in the range of 0.9-1.1 ms. Numerical simulations and in vitro measurements suggest that resonance offsets have effects that require further investigation.
Consistent detection of global predicates (1991)

A fundamental problem in debugging and monitoring is detecting whether the state of a system satisfies some predicate. If the system is distributed, then the resulting uncertainty in the state of the system makes such detection, in general, ill-defined. Three algorithms are presented for detecting global predicates in a well-defined way. These algorithms do so by interpreting predicates with respect to the communication that has occurred in the system.
Coordinated Steering and Braking Control for Roll Stability of Automated Driving Commercial Vehicles (2021)

This paper presents a coordinated steering and braking control for roll stability of automated driving commercial vehicles. A vehicle mass estimator has been developed using a recursive least square estimation. The estimated mass is utilized for the steering control in the path tracking system and the braking control in the roll-over prevention system. The proposed algorithm enhanced the path tracking performance by compensating the vehicle mass effect. In the braking control, roll-over prevention system has been designed based on the load transfer ratio which is affected by the mass. The algorithm performance has been investigated via computer simulations. The results show that the proposed algorithms reduce the lateral distance error on the split-mu road compared to the pure-pursuit method.
Dynamic response analysis of intake tower in hydroelectric power station with high surrounding rock (2017)

This paper presents results of numerical analysis for the seismic response of hydropower station intake tower in step-like ground based on artificial boundary theory. A L topography finite element model was established to verify the correctness of the proposed method of viscous elasticity boundary by consider inconsistent reflective surface. The method was applied to an intake tower, and the acceleration of bedrock was obtained by seismic inversion method, then the equivalent load of each node was calculated. Five different models were established as follow: massless foundation, consistent input viscous elasticity boundary, inconsistent input viscous elasticity boundary and whether set contact, then displacement and stress were compared, the results show that the proposed method with contact was minimal. The base plate of intake tower and the foundation were in close adhesion state in the whole process of earthquake, both sides and rear side of intake tower without through disengagement phenomena from rock, it can conclude that the intake tower in the overall stability state.
On the mechanism of renaturation of complementary DNA strands by the recA protein of Escherichia coli. (1985)

The renaturation of complementary DNA strands by the recA protein of Escherichia coli has been found to exhibit the following features. (i) Optimal renaturation occurs at recA protein levels below that required to saturate the DNA strands; saturating amounts of recA protein significantly reduce the rate of reaction. (ii) The reaction proceeds in the absence of a nucleotide cofactor but is markedly stimulated by ATP in the presence of 10 mM Mg2+. A similar stimulation occurs in the absence of ATP when the Mg2+ concentration is increased from 10 mM to 30-40 mM. (iii) Both the ATP-stimulated and the Mg2+-stimulated reactions follow apparent first-order kinetics. These results, taken together with the known effects of ATP and Mg2+ on the state of aggregation of recA protein, suggest that the association of recA monomers may play an important role in recA protein-promoted DNA renaturation.
Spectrophotometric determination of urinary oxalate with oxalate oxidase prepared from moss. (1980)

A novel spectrophotometric enzymic procedure for estimating oxalic acid in urine is described. Oxalate oxidase, prepared from moss species, converts oxalic acid to hydrogen peroxide and carbon dioxide. Hydrogen peroxide is determined enzymatically with horseradish peroxidase, by oxidative coupling of 3-methyl-2-benzothiazolinone hydrazone with N,N-dimethylaniline; the resulting indamine due is determined spectrophotometrically at 595 nm. Interfering substances are removed by adsorption to ion-exchange resins and oxidation with charcoal, thus avoiding oxalate recovery problems accompanying oxalate isolation. The procedure is rapid, sensitive, linear, and precise. Results agreed well with those obtained with a widely used chemical technique.

Cord Blood Mesenchymal Stem Cells: Potential Use in Neurological Disorders (2006)

Our previous studies demonstrate enhanced neural protective effects of cord blood (CB) cells in comparison to stem cells from adult marrow. To determine further whether mesenchymal stem cells (MSCs) derived from human umbilical cord blood (hUCB) possess optimal characteristics for neural therapy, we isolated populations of plastic-adherent CB MSCs. These cells generated CD34-, CD45-, CD11b-, CD3-, CD19- cells in culture and failed to produce CFU-M, CFU-GEMM, or CFU-GM hematopoietic colonies in methylcellulose. However, cultured CB MSCs possessed a remarkable ability to support proliferation as well as differentiation of hematopoietic cells in vitro. In addition, supernatants from cultured CB MSCs promoted survival of NT2 N neural cells and peripheral blood mononuclear cells (MNCs) cultured under conditions designed to induce cell stress and limit protein synthesis. After incubation in neural differentiation medium, CB MSCs expressed the neural cell-surface antigen A2B5, the neurofilament polypeptide NF200, the oligodendrocyte precursor marker 04, intermediate filament proteins characteristic of neural differentiation (nestin and vimentin), as well as the astrocyte marker glial fibrillary acidic protein (GFAP) and the neural progenitor marker TUJ-1. We examined the immunomodulatory effects of the CB MSCs after co-culture with murine splenocytes. Whereas spleen cells from normal C57Bl/6 mice exhibited a prominent immunoglobulin M (IgM) response after immunization with the T cell-dependent antigen sheep red blood cells, this response was significantly decreased after incubation with CB MSCs. These data indicate that CB MSCs possess multiple utilities that may contribute to their therapeutic potency in the treatment of neurological disorders.
Sobre la dinámica de la Pobreza en Colombia, 2002-2012 (2015)

In this work we are interested in investigating the dynamics of poverty in Colombia during the period 2002-2012. In particular we want to know the effect of the sectorial economic growth, the geographical composition, public social spending, the unemployment rate and the income distribution on poverty. The empirical strategy is based on a simple panel data specification, including fixed effects by department. This model relates different measures of poverty to economic growth, measured by GDP disaggregated by primary, secondary and tertiary sectors. Our results suggest that the pattern of growth and geographical differences are important for reducing poverty. In addition, we obtain evidence that implies on one hand that the unemployment rate and income inequality are responsible for persistent poverty rates, and on the other hand, social expenditures reduces poverty.
New mechanical device for effective removal of skin tags in routine health care (2009)

Skin tags (acrochordons) are exceedingly common benign skin lesions. A novel medical device in the form of a flat adhesive patch applies pressure to the base of a skin tag, leading to its removal within 3-6 days. The device was used in a clinical trial to treat and remove skin tags of the neck, upper torso, and axillae in volunteers. In this study, a total of 177 skin tags were treated in 32 individuals. One hundred seventy-two lesions fulfilled intention to treat (ITT) criteria. A majority of ITT lesions (90%) reached final assessment. Successful outcome was highest (90%) for lesions up to 1 mm in base. For lesions up to 2 mm, the rate of successful outcome was 76 percent. The desired outcome was seen in 65 percent of all ITT lesions. The cosmetic outcome after removal was excellent. Discomfort was assessed as minimal during all stages of the procedure. Analysis of data on blood flow in the skin tags during the treatment showed that the outcome was influenced by whether a decrease in blood flow was achieved immediately after application and at 2-3 days, but that the degree of occlusion was not critical. The results of this study illustrate that the device presents a new option for the management of unmet needs in the treatment of skin tags.
Epidemic routing for partially-connected ad hoc networks (2000)

Mobile ad hoc routing protocols allow nodes with wireless adaptors to communicate with one another without any pre-existing network infrastructure. Existing ad hoc routing protocols, while robust to rapidly changing network topology, assume the presence of a connected path from source to destination. Given power limitations, the advent of short-range wireless networks, and the wide physical conditions over which ad hoc networks must be deployed, in some scenarios it is likely that this assumption is invalid. In this work, we develop techniques to deliver messages in the case where there is never a connected path from source to destination or when a network partition exists at the time a message is originated. To this end, we introduce Epidemic Routing, where random pair-wise exchanges of messages among mobile hosts ensure eventual message delivery. The goals of Epidemic Routing are to: i) maximize message delivery rate, ii) minimize message latency, and iii) minimize the total resources consumed in message delivery. Through an implementation in the Monarch simulator, we show that Epidemic Routing achieves eventual delivery of 100 % of messages with reasonable aggregate resource consumption in a number of interesting scenarios. 1
Irreversible, direct bonding of nanoporous polymer membranes to PDMS or glass microdevices (2010)

A method for integrating porous polymer membranes such as polycarbonate, polyethersulfone and polyethylene terephthalate to microfluidic devices is described. The use of 3-aminopropyltriethoxysilane as a chemical crosslinking agent was extended to integrate membranes with PDMS and glass microfluidic channels. A strong, irreversible bond between the membranes and microfluidic structure was achieved. The bonding strength in the APTES treated devices was significantly greater than in devices fabricated using either a PDMS "glue" or two-part epoxy bonding method. Evaluation of a filtering microdevice and the pore structure via SEM indicates the APTES conjugation does not significantly alter the membrane transport function and pore morphology.
