[Adult T cell lymphoma/leukemia with alopecia, huge tumors of scalp and wide destruction of cerebral bone]. (1991)

We reported rare manifestations of adult T cell lymphoma/leukemia. Patient was 41 year-old woman who has had progressive alopecia from childhood and developed multiple huge tumors (largest 10 x 15 cm) of scalp and wide destruction of cerebral bone at age of 39. A few abnormal lymphocytes (10%) appeared in the peripheral smear. Surface markers of peripheral lymphocytes showed two populations of CD4+/CD8- and CD4+/CD8+. HTLV-1 proviral DNA was demonstrated in the peripheral lymphocytes. Serum anti-ATLA antibodies was positive (X80). Biopsy of tumor revealed diffuse and large cell type of malignant lymphoma. Magnetic resonance imaging of head showed that tumors lysed the bone and invaded into cerebral regions. She was treated with CHOP regimen and irradiation, resulting of decreased tumor size and population of CD4+/CD8+.
Combing Laser Doping and Wet Chemical Etch Back for Industrial Selective Emitter Solar Cells (2012)

In this paper, we present results of the development of a selective emitter structure for crystalline silicon solar cells suitable for industrial mass production. The process sequence follows the approach first introduced by Volk et al [1]. Laser doping is performed directly after emitter diffusion. In a second step, the emitter is etched back homogenously without a mask to improve the emitter quality and remove the dead layer. While the resulting selective emitter yields a higher efficiency potential than with laser doping alone, the simplicity of the homogenous etch back step, results in a lower invest and COO than a “Mask and Etch Back” approach. On life time samples the processes of emitter diffusion, laser doping and emitter etch back were thoroughly studied. Development was performed on industrial production equipment in preparation for a transfer of this technology to mass production. The optimization of the selective emitter on 156 mm cz-solar cells yielded an average efficiency of 18,60 %, which corresponded to an efficiency gain of 0,3% compared to our baseline.
Promoter hypermethylation in circulating blood cells identifies prostate cancer progression (2007)

Promoter hypermethylation of circulating cell DNA has been advocated as a diagnostic marker for prostate cancer, but its prognostic use is currently unclear. To assess this role, we compared hypermethylation of circulating cell DNA from prostate cancer patients with (Group 1, n = 20) and without (Group 2, n = 22) disease progression and age-matched controls (benign prostatic hyperplasia, Group 3, n = 22). We measured hypermethylation of 10 gene promoters in 2 sequential venous samples, obtained at diagnosis and during disease progression (median time, 15 months later). Matched time samples were obtained in the nonprogressing patients. We found that more hypermethylation was detected in the diagnostic sample from the patients with cancer than in controls for GSTP1, RASSF1 alpha, APC and RAR beta (p < 0.0001). Patients undergoing disease progression had a significant increase in methylation levels of these 4 genes when compared to the other patients (p < 0.001). Patients at risk of disease progression have higher detectable concentrations of circulating cell hypermethylation, than those without progression. The extent of this hypermethylation increases during disease progression and can be used to identify the extent and duration of treatment response in prostate cancer.
Cardiac Biointerventions Whatever Happened to Stem Cell and Gene Therapy? (2012)

Angiogenic gene therapy and stem cell administration represent two "biologic" interventions for the treatment of cardiac disease that were first introduced more than 15 years ago but still have not achieved approval for clinical use for the treatment of myocardial ischemia and heart failure. Challenges that have been encountered in the clinical testing of these new treatment strategies have included a lack of placebo controls in phase I surgical trials and the incorporation of potentially ineffectual agent delivery via intracoronary routes. Although enthusiasm for these approaches may therefore have ebbed, new refinements in these technologies and insights into their appropriate clinical testing suggest that a resurgence of interest in these "biointerventions" may be expected in the near future.
Context-Aware Online Spatiotemporal Traffic Prediction (2014)

With the availability of traffic sensors data, various techniques have been proposed to make congestion prediction by utilizing those datasets. One key challenge in predicting traffic congestion is how much to rely on the historical data v.s. The real-time data. To better utilize both the historical and real-time data, in this paper we propose a novel online framework that could learn the current situation from the real-time data and predict the future using the most effective predictor in this situation from a set of predictors that are trained using historical data. In particular, the proposed framework uses a set of base predictors (e.g. A Support Vector Machine or a Bayes classifier) and learns in real-time the most effective one to use in different contexts (e.g. Time, location, weather condition). As real-time traffic data arrives, the context space is adaptively partitioned in order to efficiently estimate the effectiveness of each predictor in different contexts. We obtain and prove both short-term and long-term performance guarantees (bounds) for our online algorithm. Our experiments with real-world data in real-life conditions show that the proposed approach significantly outperforms existing solutions.
Baiting the Cross-Face Nerve Graft With Temporary Hypoglossal Hookup (2004)

Baiting the cross-face nerve graft via temporary hookup to the distal hypoglossal nerve and tongue musculature appears to improve nerve ingrowth through a nerve graft across the face, although a corresponding improvement in facial muscle function was not observed.
Solid state physics program. UHV Moessbauer emission spectra in thin iron films (1971)

Mossbauer spectra of thin iron films in the thickness range 1 Å to 42 Å at temperatures from 15°K to 350°K have been studied.
Demand-driven points-to analysis for Java (2005)

We present a points-to analysis technique suitable for environments with small time and memory budgets, such as just-in-time (JIT) compilers and interactive development environments (IDEs). Our technique is demand-driven, performing only the work necessary to answer each query (a request for a variable's points-to information) issued by a client. In cases where even the demand-driven approach exceeds the time budget for a query, we employ early termination, i.e., stopping the analysis prematurely and returning an over-approximated result to the client. Our technique improves on previous demand-driven points-to analysis algorithms [17, 33] by achieving much higher precision under small time budgets and early termination.We formulate Andersen's analysis [5] for Java as a CFL-reachability problem [33]. This formulation shows that Andersen's analysis for Java is a balanced-parentheses problem, an insight that enables our new techniques. We exploit the balanced parentheses structure to approximate Andersen's analysis by regularizing the CFL-reachability problem, yielding an asymptotically cheaper algorithm. We also show how to regain most of the precision lost in the regular approximation as needed through refinement. Our evaluation shows that our regularization and refinement approach achieves nearly the precision of field-sensitive Andersen's analysis in time budgets as small as 2ms per query. Our technique can yield speedups of up to 16x over computing an exhaustive Andersen's analysis for some clients, with little to no precision loss.
Microfluidic system incorporating layer-by-layer nanofabricated capsules (2003)

A microfluidic system was designed, fabricated and implemented to study the behavior of polyelectrolyte capsules flowing in microscale channels. The silicon component of the system contains microchannels that leads into constrictions, which were fabricated using lithography techniques. Polyelectrolyte microcapsules were also fabricated with well-known layer-by-layer assembly technique, on a spherical template. Once the template was removed, the resulting hollow capsules were introduced into the system. The behavior of the capsules at the constrictions was visualized and the properties of the capsules were investigated. Capsules recovered from the system appear to have a undergone a plastic deformation.

Prediction of the Clearing Temperatures of a Series of Liquid Crystals from Molecular Structure (1999)

A quantitative structure−property relationship (QSPR) investigation was performed to develop a mathematical link between molecular structure and the clearing temperature of a series of structurally related liquid crystals. Molecular structures were encoded by a series of numerical descriptors encoding information regarding size, shape, and the ability to participate in intermolecular interactions. A genetic algorithm feature selection routine was utilized to select high-quality subsets of these descriptors for use in computational neural network models. A successful 10-descriptor model was developed using 318 compounds with a root-mean-square error of 5.4 K for the clearing temperature for the compounds in an external prediction set not used in model development.
An open schema for XML data in Hive (2014)

Big data in XML format poses a challenge to distributed data systems. This paper proposes an open Hive schema approach to XML data placement in Hadoop. Placing XML data in Hive with this generic schema to build column-oriented and OLAP-focused XML data warehouse of heterogeneous content has benefits for data access, maintenance and scalability.
Detection of Metabolic Disorders (1968)

Abstract A scheme for detection of metabolic disorders utilizing commercial dip tests, spot plate tests, and paper chromatographic tests is presented. Specific details are given for preparation and development of chromatograms for routine screening of urine specimens for disorders of amino acid and carbohydrate metabolism. Specialized tests for confirming positive findings in the screening procedures are described. The results are interpreted with regard to the variations encountered in testing normal infants and children, children hospitalized with a variety of diseases, and mentally retarded children. Examples of specific and generalized aminoacidurias are given.
Malignant pheochromocytoma with features suggesting the brown-séquard syndrome.A case report (1977)

A case of malignant pheochromocytoma arising from the abdominal preaortic chromaffin tissue is presented. Of particular note is that right hemiplegia associated with sensory disturbances, compatible with the Brown-Séquard syndrome, was an outstanding early clinical manifestation. The patient finally developed signs of complete transection of the spinal cord which was caused by metastasis of the tumor to the cervical spines. The neurological abnormalities observed in the present case were so unusual in pheochromocytoma as to lead initially a diagnosis of cord tumor. Autopsy findings well supported the clinical diagnosis. Cases like this have not been reported so far. Cancer 40:402–405, 1977.
Neurogenic inf ammation in an animal model of neuropathic pain (1998)

Loose ligation of a rat sciatic nerve (chronic constriction injury (CCI) model) provokes signs and symptoms like those observed in reflex sympathetic dystrophy (RSD) patients. Primary afferent nociceptive C-fibers seem to be involved in an afferent orthodromic as well as in an efferent antidromic manner. In this study we hypothesize that consequent to development of antidromic impulses in C-nociceptive afferents, neuropeptides released from peripheral endings of these fibers, increase skin blood flow (SBF), vascular permeability, and tissue accumulation of polymorphonuclear leukocytes (PMNs). Collectively, these phenomena have been referred to as neurogenic inflammation. To investigate the presence of neurogenic inflammation in the CCI-model, we assessed skin blood flow (SBF) as well as the level of edema and accumulation of PMNs in muscle tissue obtained from the affected hindpaw. SBF was measured, by means of laser Doppler flowmetry, before ligation as well as at day 4 after ligation. At day 4, SBF measurements were performed before and after abolition of the capability of C-fibers to mediate a vasodilator response. To this end, capsaicin was applied perineurally. Increased vascular permeability was inferred from the level of edema of muscle tissue as determined by assessment of wet/dry weight ratios of muscle biopsies. PMN accumulation was investigated by enzymatic detection of myeloperoxidase (MPO) activity in muscle biopsies. Compared with preligation values, at day 4 SBF was increased more than twofold (p < 0.05). The latter response was annihilated by capsaicin application. Compared with sham operated controls, wet/dry ratios were higher in the ligated animals (1.104 vs. 1.068; p < 0.05). Likewise, when compared with sham operated controls, MPO activity was found to be increased in the ligated hindpaw (Optic Density 0.15 vs. 0.89; p < 0.001). In conclusion, the findings of this study indicate that loose ligation of a sciatic nerve induces an inflammatory response in the ipsilateral hindpaw, which most likely is mediated by release of neuropeptides from the peripheral endings of antidromically acting nociceptive C-fibres.
Amyloidosis complicating cystic fibrosis. (1993)

Two patients with cystic fibrosis developed acute onset nephrotic syndrome and died within three months of presentation. Examination of renal biopsy specimens indicated amyloid. The onset of proteinuria or a fall in baseline renal function should alert the physician to this rare complication.
Acoustic fatigue life prediction for nonlinear structures with multiple resonant modes (1992)

This report documents an effort to develop practical and accurate methods for estimating the fatigue lives of complex aerospace structures subjected to intense random excitations. The emphasis of the current program is to construct analytical schemes for performing fatigue life estimates for structures that exhibit nonlinear vibration behavior and that have numerous resonant modes contributing to the response.
REVIEW COPY NOT FOR DISTRIBUTION Onset of Motion and Dynamic Reordering of a Vortex Lattice (2005)

Time resolved transport measurements on a driven vortex lattice in an undoped 2H-NbSe2 crystal show that the response to a current pulse is governed by healing of defects as the lattice evolves from stationary to moving steady state, and that the response time reflects the degree of order in the initial vortex state. We find that stationary field cooled vortex lattices become more ordered with decreasing temperature and identify a temperature below which a qualitative change in the response from step-wise and slow to smooth and fast signals the disappearance of topological defects.
Gyrotropic response in the absence of a bias field (2012)

Electromagnetic materials lacking local time-reversal symmetry, such as gyrotropic materials, are of keen interest and importance both scientifically and technologically. Scientifically, topologically nontrivial phenomena, such as photonic chiral edge states, allow for reflection-free transport even in the presence of large disorder. Technologically, nonreciprocal photonic devices, such as optical isolators and circulators, play critical roles in optical communication and computing technologies because of their ability to eliminate cross-talk and feedback. Nevertheless, most known natural materials that lack local time-reversal symmetry require strong external fields and function only in a limited range of the electromagnetic spectrum. By taking advantage of metamaterials capable of translating the property of unidirectional active electronic circuits into effective dielectric response, we introduce a microwave gyrotropic metamaterial that does not require an external magnetic bias. Strong bulk Faraday-like effects, observed in both simulations and experiments, confirm nonreciprocity of the effective medium. This approach is scalable to many other wavelengths, and it also illustrates an opportunity to synthesize exotic electromagnetic materials.
Power conversion and control using a current sensing power MOSFET (2002)

Current-sensing power MOSFETs (SENSEFETs) provide signals proportional to the device current which can be used for overcurrent protection and current feedback. The authors describe an experimental DC-to-DC converter using a SENSEFET switch. The method of processing the sense signal and designing the current feedback is explained. The characteristics of the current sense signal are studied for a converter supplying both an R-L load and a motor load. The current-sensing power MOSFET is suitable for such applications as current regulated power converters and motor drives. >
Rethinking opportunistic routing using space syntax (2011)

Communication in mobile opportunistic networks is primarily achieved through a variety of store-carry-and-forward techniques, where node mobility is exploited for end-to-end data delivery. The main routing challenges these networks face is determining when to forward a message and which nodes to forward it to, ultimately resulting in varying delay and cost trade-offs. Routing solutions to date heavily rely on assumptions regarding the underlying environment and node capabilities, which may be unrealistic in many cases. In this paper, we propose building upon Space Syntax in order to make forwarding decisions with more realistic assumptions about the underlying environment. Space Syntax metrics have long been used in the field of architecture to model natural mobility patterns by analyzing spacial configurations. To adapt Space Syntax to opportunistic routing, we propose our popularity index metric, which is based on core Space Syntax metrics. This popularity index depends on factors in the environment that do not frequently change, and therefore, can be more realistically adopted and deployed when compared to other opportunistic routing algorithms. We introduce two simple forwarding algorithms based on the popularity index and compare their performance to other approaches. Our initial evaluation shows that Space Syntax based routing performs relatively well compared to state-of-the-art solutions with the added advantage of being more realistic and as a result easier to deploy.

Transmission of aggregate VoD streams using playback rate (2002)

In video-on-demand (VoD) systems, using the entire frame-size sequence for each video stream, the VoD service provider can derive a video transport schedule which will cause neither buffer overflow nor buffer starvation without requiring excessive amounts of network bandwidth and buffer space. Specifically, such a transport schedule uses temporal averaging to reduce the rate variability of a video stream. We propose a simple and efficient VBR VoD-stream transport mechanism called the play-back rate transport with minimum rate guaranteed (PBRT-MRG), which exploits statistical multiplexing as well as temporal averaging. The proposed scheme provides statistical loss guarantees (instead of absolute loss-freedom guarantees) to maximize network utilization. Temporal averaging is done through buffering both at the server and at receivers. To exploit the advantages of statistical multiplexing, a set of VoD streams are multiplexed onto a common transport channel. For the aggregated video streams which are averaged temporally and spatially, we present a simple transport mechanism and a call-admission scheme both of which together provide statistical loss guarantees. Our empirical study shows that one can provide a VoD service without requiring any complex control while achieving high bandwidth/buffer utilization at a reasonable build-up delay. In one case, the proposed scheme is shown to save buffer requirement by as much as three orders of magnitude for the same bandwidth usage.
Nest boxes for wildlife (2011)

Many people enjoy having wildlife on their property and will manage their property to make it more inviting for specific species. Successful wildlife habitat management begins with identifying the habitat components (food, cover, water and space) of the species of interest that are in shortest supply and then providing them.
