New Model for Applied University Research and Professional Development:Tren Urbano Program (2007)

At the beginning of the 1990s, Puerto Rico started to develop its first modern urban rail transit system (the Tren Urbano program). Professional development and academic research was incorporated into the Tren Urbano program through technology transfer activities. The Tren Urbano program was driven by the unique Puerto Rican situation and turned out to be a model of technology transfer in public transportation for American and other nations. This program has been carried out for over 13 years through corporation among Puerto Rico universities, MIT, and railway agencies, and has experienced the whole process of planning, construction, fine-tuning, operation and policy analyzing. It is believed that this corporation played an important role in optimizing the planning of the system, improving the project quality and construction efficiency, promoting local development of rail transportation related industries, encouraging the application and research of new technologies, and in the training of a large amount of urban rail transportation planning and operation professionals. It is also believed that this program established a new model for construction of urban rail transportation facilities in Latin America. Puerto Rico's experience could be helpful for urban rail transportation development in China.

Reducing Static Energy in Supercomputer Interconnection Networks Using Topology-Aware Partitioning (2015)

The key to reducing static energy in supercomputers is switching off their unused components. Routers are the major components of a supercomputer. Whether routers can be effectively switched off or not has become the key to static energy management for supercomputers. For many typical applications, the routers in a supercomputer exhibit low utilization. However, there is no effective method to switch the routers off when they are idle. By analyzing the router occupancy in time and space, for the first time, we present a routing-policy guided topology partitioning methodology to solve this problem. We propose topology partitioning methods for three kinds of commonly used topologies (mesh, torus and fat-tree) equipped with the three most popular routing policies (deterministic routing, directionally adaptive routing and fully adaptive routing). Based on the above methods, we propose the key techniques required in this topology partitioning based static energy management in supercomputer interconnection networks to switch off unused routers in both time and space dimensions. Three topology-aware resource allocation algorithms have been developed to handle effectively different job-mixes running on a supercomputer. We validate the effectiveness of our methodology by using Tianhe-2 and a simulator for the aforementioned topologies and routing policies. The energy savings achieved on a subsystem of Tianhe-2 range from 3.8 to 79.7 percent. This translates into a yearly energy cost reduction of up to half a million US dollars for Tianhe-2.
TWGDAM Validation of the AmpFℓSTR Profiler Plus and AmpF∓STR COfiler STR Multiplex Systems Using Capillary Electrophoresis (2001)

Prior to forensic implementation, a profiling system requires validation following the recommendations presented by the Technical Working Group on DNA Analysis Methods (TWGDAM). In this work two such systems, AmpFlSTR Profiler Plus and AmpFfSTR COfiler have been validated according to the guidelines provided by TWGDAM. Profiler Plus and COfiler simultaneously amplify nine and six STR loci respectively; both also amplify a portion of the amelogenin gene. Performance of the two STR multiplex systems under conditions set forth by TWGDAM was robust and reproducible, indicating that these systems are suitable for use in forensic analysis. Additionally, specific sections of the TWGDAM validation guidelines are especially valuable in terms of familiarizing users with particular limitations of the systems prior to taking on casework.

A Comparison of Dementia in Alzheimer's Disease and Multiple Sclerosis (1989)

We compared results of comprehensive neuropsychological testing in 42 patients with clinically diagnosed Alzheimer's disease (AD) and in an equal number of patients with clinically definite chronic-progressive multiple sclerosis. Age, sex, and education were controlled using demographically corrected T scores based on a large normal sample. Both groups showed significant impairment on the test battery, but the degree of dementia was more severe in the patients with AD. A deviation score analysis, controlling for overall level of cognitive impairment, revealed significant differences between the groups. Alzheimer's disease was associated with relatively greater impairment of learning, memory, and verbal skills, whereas the MS group showed greater relative impairment of attention, incidental memory, and psychomotor functions. These data suggest that both the degree and pattern of mental impairement differ in patients with AD and patients with multiple sclerosis. Our results support a distinction between "gray matter" and "white matter" dementia, and may help clarify the issue of "cortical" vs "subcortical" dementia by demonstrating neuropsychological differences based on secure neuropathologic distinctions.
Development of a switched-capacitor DC/DC boost converter with continuous input current waveform (1999)

A new switched-capacitor (SC)-based dc/dc boost converter is presented. It features good regulation capability and continuous input current, giving lower conducted electromagnetic interference with the supply network than classical SC converters. The converter is realized by using two quasi-switched-capacitor boost converter cells. The dc voltage conversion ratio is controlled by the gate-source voltage of a quasi-switch in each cell, in order to adjust the charging trajectory of the capacitors. By renouncing inductive elements, the converter can be implemented in small size, light weight, high power density, and it is possible to fabricate it in an IC form. A prototype of a 20 W, 6 V/9 V dc/dc boost converter with overall efficiency of 74% and power density of 10 W/in/sup 3/ has been built. The state-space averaging technique is applied to study the static and dynamic behaviors of the converter.
Etanercept Treatment in Children With New-Onset Type 1 Diabetes (2009)

In this small pilot study, treatment of pediatric patients newly diagnosed with type 1 diabetes with etanercept resulted in lower A1C and increased endogenous insulin production, suggesting preservation of beta-cell function. A larger study is needed to further explore safety and efficacy.
The Significance of π Interactions in Group 11 Complexes with N-Heterocyclic Carbenes (2004)

The nature of the chemical bond in mixed carbene−halogen complexes (1)TMX (X = F−I) and bis(carbene) complexes (1)2TM+ of group 11 metals (TM = Cu, Ag, Au) with imidazol-1-ylidene (1) as ligand has been investigated at the BP86 level of theory using an energy decomposition analysis (EDA). The metal−carbene bonds are mainly held together by classical electrostatic attraction, which contributes >65% of the binding interactions. The metal−carbene bonds are very strong. In the bis(carbene) complexes, the N-heterocyclic carbene ligand 1 is bonded even more strongly than in the mixed carbene−halogen complexes. In the bis(carbene) complexes, orbital interactions are slightly more important than in the mixed carbene−halogen complexes but the covalent contribution is always <35% of the total attractive interaction. The orbital interaction part of the bonding has only ∼20% π back-bonding. The calculated data are not very different from previous EDA results for the Fischer carbene complex (CO)5W−C(OH)2. The EDA results suggest that R2C←MLn π back-donation in complexes with N-heterocyclic carbenes is not substantially smaller than in classical Fischer carbene complexes bearing two π donor groups R.
A systematic review of the use of hydrocolloids in the treatment of pressure ulcers (2008)

Based on the studies included in this review, hydrocolloids are frequently used in the treatment of grade 2 and 3 pressure ulcers and are more effective and less expensive than gauze dressings. Compared with alginates, polyurethane dressings, less-contact layers, topical enzymes and biosynthetic dressings, hydrocolloids are less effective.
Will tiny beans conquer the world again? [Java language] (1996)

The paper discusses the Java language and its component technology Java Beans. Java Beans allows middleware to work across all desktops. Thus, it has a slight chance against ActiveX. ActiveX compiles into Wintel binaries, while Java compiles into J-code. Microsoft is about to apply some pressure by flooding the Internet with compelling applications that require users to adopt ActiveX.

Numerical modeling of atmospheric scintillation (1986)

Computational techniques for modeling atmospheric propagation in conditions of saturated scintillation are discussed. Results are presented for the propagation and adaptive compensation of laser beams over such paths.
Providing policy control over object operations in a mach based system (1995)

In both secure and safety-critical systems it is desirable to have a very clear relationship between the system&apos;s mandatory security pol-icy and its proven operational semantics. This relationship is made clearer if the system ar-chitecture provides strong separation between the enforcement mechanisms and the policy decisions, and if the policy decision software is clearly identi®able in the system&apos;s architec-ture. This paper describes a prototype Unix sys-tem based on Mach which provides manda-tory control over all kernel-supported opera-tions. The prototype work modi®ed the Mach kernel by extending its limited control mech-anisms based on the Mach port right. The control extensions allow a mandatory control policy to specify control over not only access to an object via a port right, but over the indi-vidual services supported by the object. The mandatory security policy is implemented in an external Security Server which provides very strong separation between policy enforce-ment and policy decision software. This makes it possible to support a wide range of security policies with no change to the kernel or appli-cations. 1

Multimodal imaging and computer assisted diagnosis for functional tumour characterisation (2005)

Radiological modalities, especially CT, mainly provide morphological and structural information with high spatial resolution covering large volumes. Novel developments, which are predominantly MR-based, also deliver 'functional' information, which can be used for individual characterisation of tumour biology. Both aspects and modalities, additionally complemented by ultrasound, have to be combined in the radiological workflow of cancer patients including volumetric visualisation, information extraction from multimodal imaging, quantitative surrogates, intelligent interpretation assistance and image-guided procedures. Based on volumetric visualisation and the generation of 3D+t maps, CAD tools have to address registration of different image series from different modalities, and extraction of quantitative surrogates. The latter will then serve tumour characterisation, therapeutic decision-making, image-guided procedures and efficacy evaluation.
Analysis of Electromagnetic Compatibility Between Radar Stations and 4 GHz Fixed-Satellite Earth Stations (1994)

The susceptibility of 3700 to 4200 MHz fixed-satellite service earth stations to interference from radar signals, and the mechanisms by which such interference can occur, are examined. It is shown that interference can occur even if all currently applicable NTIA and FCC spectrum engineering requirements for radar emissions and earth station receiver systems are satisfied. It is further shown that while most interference problems can be resolved by installing appropriate radio frequency (RF) filtering on either the radar transmitter RF output or the earth station RF input, determination of the system that requires filtering depends critically upon the interference coupling mechanism. Methods for determining the interference coupling mechanism are presented.
Estimation of free thyroid hormone concentrations in the clinical laboratory. (1986)

A multiplicity of tests have come into routine use for the estimation of the concentrations of free thyroid hormones in serum and plasma since the introduction, almost three decades ago, of the hypothesis that only the free thyroid hormone is metabolically active. Most of these tests give estimates of considerable diagnostic value, although results may be unreliable in some clinical situations. This review outlines the methods currently available for estimating free thyroid hormones and highlights the extrathyroidal and physiological factors influencing the results of such tests, particularly for the analog-based techniques.
TFBScluster: a resource for the characterization of transcriptional regulatory networks (2005)

One major challenge of the post-sequencing era of the human genome project will be the functional annotation of the non-coding portion of the genome, in particular gene regulatory sequences. We have developed a new web-based tool, TFBScluster, which performs genome-wide identification of transcription factor binding site clusters that are conserved in multiple mammalian genomes. Clusters representing candidate gene regulatory elements can be filtered further, based on the presence or absence of additional user-defined DNA sequence motifs or by constraining the orientation or order of binding sites. Comprehensive results files, returned by email, are designed to facilitate experimental validation of computationally identified candidate gene regulatory sequences. TFBScluster, therefore, has the potential to contribute to deciphering transcriptional networks that regulate a wide range of mammalian developmental processes.
Surface cleaning of silicon wafer by laser sparking (2001)

The removal of small particles (∼1 μm diameter) on a silicon wafer surface has been carried out by laser sparking, i.e., an intense laser pulse is focused in air generating a gas breakdown. It has been found that the airborne plasma shock waves induced by laser sparking initiated above the surface can successfully remove the particles such as tungsten, copper, and gold from the silicon surface. This new cleaning technique provides superior characteristics as an efficient, fast, damage-free process compared with conventional laser cleaning employing direct interactions between laser pulse and particles. The basic idea behind this technique and how to apply it for cleaning of the surface are described in detail. The cleaning mechanism is also discussed by comparing the adhesion force of a particle on a surface with the pressure of the shock wave generated by laser sparking in air.
Handoff prioritisation with implicithannel reservation in distributed dynamic channelssignment algorithms (1999)

A new distributed dynamic channel assignment scheme with implicit channel reservation for handoff prioritisation is proposed. This scheme reduces the degree of computation and communications among base stations required for channel reservation and achieves a capacity similar to that of the maximum packing algorithm. For 40 total channels, the proposed algorithm achieves a 116% capacity increase relative to the non-prioritised fixed channel assignment (FCA) scheme and 93% relative to FCA with optimum channel reservation.
Replacement of Spectrum Sensing and Avoidance of Hidden Terminal for Cognitive Radio (2008)

Cognitive radio technique has been recently proposed as a novel approach for improving the utilization of the precious limited radio resources, by letting secondary users access primary users' spectrum if not used. There are two major challenges for cognitive radio: spectrum sensing and hidden terminal problem. In this paper, a novel network structure is proposed to separate the spectrum sensing task from the secondary users. The service providers for the secondary users need to place sensing devices within the primary users' networks. These sensing devices sense the primary users' activity. The sensing devices also decide whether to admit a secondary user's transmission. A low-temperature handshake technique is proposed for communications between the secondary users and the sensing devices. A new cognitive cycle is proposed, and the detailed protocol is constructed. The proposed protocol is analyzed using the theory of Lame curve. The problems of optimally locating a sensing device and minimizing the number of sensing devices under the constraint of the maximal collision probability are studied and solved. A performance upper bound is also derived for a special case. From simulation results, the effectiveness of the proposed scheme is demonstrated.
[Trichorhinophalangeal syndrome : analysis of craniofacial architecture in six cases (author's transl)]. (1981)

The trichorhinophalangeal syndrome, first described by Giedon in 1966, is a condition characterized not only by skeletal, nasal, and phanerian anomalies, but by typical changes in craniofacial architecture : the vertical height of the face and cranium is increased, and there is broadening of the sagittal maxillomandibular width compensatory bilateral retroalveoli. According to Delaire, who analyzed the craniofacial architecture, the primary etiological feature of the characteristic craniofacial modifications observed in this syndrome is a reduction in size of the craniofacial basal structure.
Initial Description of Pilotage and Tug Services in the Context of e-Navigation (2020)

The International Maritime Organization (IMO)’s Maritime Safety Committee (MSC), at its 101st session (5 to 14 June 2019), adopted Resolution MSC.467(101) on the guidance on the definition and harmonization of the format and structure of maritime services in the context of e-Navigation and agreed to consolidate the descriptions of maritime services and to consider them together with all involved international organizations and interested member states, in order to harmonize the provision and exchange of maritime information and data. In doing so, the MSC also approved the initial descriptions of maritime services in the context of e-Navigation (IMO MSC.1/Circ.1610), which had been prepared by the Sub-Committee on Navigation, Communications and Search and Rescue, at its sixth session (16 to 25 January 2019). The information contained in this paper constitutes the descriptions of two selected examples of maritime services, an initial contribution for the harmonization of the formats and structures of pilotage and tug services. The initial description of each of maritime services is expected to be next periodically updated, taking into account developments and related work on international harmonization.
Estimating customer defection in personal retail banking (2002)

Using Juster’s probability scale, this study examines a sample of 881 customers’ self‐reported estimates of probable defection from their main bank. One year later these customers’ statuses with their main bank were reviewed, allowing comparison of intended with actual defection. This methodology allows not only investigation of the Juster scale’s performance in a “subscription” type market but also identification of those customers with a predisposition to switch banks. Bank management can then decide if and how they might address their switch‐prone customers. Respondents were asked to allocate their probability of closing all accounts at their main bank in the next 12 months. The sample estimate was 10 percent while the actual defection result was 5 percent. While this may seem somewhat inaccurate, similar studies in the literature report the tendency of the Juster scale to over‐estimate switching behaviour, but its estimates have consistently proved superior previously to those derived from attitudinally based intention‐to‐buy scales and at least the equal of the Conversion Model.
