Effect of case mix on feature selection in the computerized classification of mammographic lesions (2002)

One potential limitation of computer-aided diagnosis (CAD) studies is that a computerized method may be trained and tested on a database comprised of a limited number of cases. Thus, the performance of the CAD method may depend on the subtlety of the lesions (i.e., the case mix) in the database. The purpose of this study is to evaluate the effect of case-mix on feature selection and the performance of a computerized classification method trained on a limited database.
Measurement of bend-induced nonlinearities in large-mode-area fibers (2008)

We present the first direct measurements of enhanced nonlinearities in large-mode-area fibers due to bend induced reductions in effective area. Both Raman scattering and self-phase modulation are observed to increase in tightly coiled fibers. The measured increase in nonlinearity compares well with predictions from simulations of the modal effective area.
Far-infrared observations of NGC 7027 (1977)

Far-infrared observations of the planetary nebula NGC 7027 show that its total infrared flux is 2.4 by 10 to the -10th power W/sq m, approximately one-third of which is emitted in each of the intervals from 1 to 17, 17 to 30, and 30 to 300 microns. Sufficient energy to account for the corresponding infrared luminosity of 23,000 times the solar value at 1.77 kpc is available as diffuse nebular radiation or from moderate competition between dust and gas for Lyman continuum photons. Most of the infrared flux arises from a source comparable in size to the H II region. The flux at wavelengths greater than 17 microns can be attributed to grains with temperatures not exceeding 120 K and total mass such that the gas-to-dust ratio is close to the lower limit allowed by cosmic abundances.
Pomegranate peel extract lessens histopathologic changes and restores antioxidant homeostasis in the hippocampus of rats with aluminium chloride-induced Alzheimer’s disease (2020)

Objective: To investigate the neuroprotective efficacy of pomegranate and ellagic acid on the histopathological changes in the hippocampus of an aluminium chloride (AlCl3) induced rat model of Alzheimer’s disease.Methods: Sprague Dawley rats were divided into 4 groups (n=10 each): Group I : serving as negative control; Group II, Alzheimer model, induced by administration of 17 mg/kg bw AlCl3; Group III, administered the same dose of AlCl3 with 50 mg/kg of pomegranate peel extract and Group IV : administered ellagic acid (50 mg/kg) in addition to the same dose of AlCl3. The medication given to all groups continued for 28 days. All were given the compounds by gastric gavage. Radial arm maze test, hippocampus antioxidant markers, histopathology of the dentate gyrus, and CA3 of the hippocampus were evaluated.Results: Rats treated with pomegranate peel extract exposed to radial arm maze test showed less number of errors and reduced time needed to reach the criterion. There was an increase in the levels of glutathione, catalase, and total antioxidant capacity and decreased lipid peroxidation products. Histopathological features in dentate gyrus and CA3 as apoptosis and chromatolysis of pyramidal cells and granular layer, respectively, were decreased. Alzheimer characteristic neurofibrillary tangles and senile plaques were reduced. Treatment with ellagic acid ameliorated the pathological results but to a statistically lower level.Conclusions: Pomegranate peel extract alleviates memory deficit and restores antioxidant homeostasis following degenerative changes in the hippocampus induced by aluminium chloride in rats.
Repeatability of Standardized and Normalized Relative CBV in Patients with Newly Diagnosed Glioblastoma (2015)

The ΔR2* estimation methods that incorporate leakage correction offer the best repeatability for relative CBV, with standardized relative CBV being less variable and requiring fewer participants to detect a change compared with normalized relative CBV.
DISENTANGLING FRAILTY FROM DISABILITY AND DISEASE: AN EMPIRICAL ANALYSIS OF FRAILTY INSTRUMENTS (2017)

Frailty is conceptualized as an increased vulnerability of older adults to develop adverse health outcomes when encountering a stressor. However, operationalization has proven challenging, with numerous frailty instruments that include a wide range of age-related domains, such as physical capacity, disease, and disability. Inclusion of diseases and disability in frailty instruments obfuscates the frailty construct. Fried (2004) has argued that frailty, disability and comorbidity are interrelated but distinct entities. This distinction is critical for understanding the etiology and consequences of frailty, and for devising prevention and treatment strategies. Here we conduct a literature review to identify articles that examined: a) risk factors (such as inflammatory diseases) for frailty; and b) frailty as a risk factor for disability. We then categorize frailty instruments (n=67) used in the identified articles into 4 categories by their measures: 1) Physical Capacity plus other domains, sans disability or disease (n=26); 2) Disease plus other domains, sans disability (n=7); 3) Disability plus other domains, sans disease (n=17); and 4) Disease and Disability plus other domains (n=17). This review will provide empirical data on the use of different categories of frailty instruments in studies of upstream risk factors and of subsequent disability. Preliminary results show that 33% (10/30) of studies on risk factors for frailty used a frailty instrument containing measures of diseases and/or disability. We suggest that studies seeking to examine etiologic factors of frailty or consequences of frailty, such as disability, should not use operational definitions of frailty that include these overlapping but distinct domains.

Resolution recovery on list mode MLEM reconstruction for Dynamic Cardiac SPECT system (2022)

The Dynamic Cardiac SPECT (DC-SPECT) system is being developed at the Massachusetts General Hospital, featuring a static cardio focus asymmetrical geometry enabling simultaneous high resolution and high sensitivity imaging. Among 14 design iterations of the DC-SPECT with varying number of detector heads, system sensitivity and system resolution, the current version being fabricated features 10 mm FWHM geometrical resolution (without resolution recovery) and 0.07% sensitivity; this is 1.5x resolution gain and 7x sensitivity gain compared to a conventional dual head gamma camera. This work presents improvement in imaging resolution by implementing a spatially variant point spread function (SV-PSF) with list mode MLEM reconstruction. A resolution recovery method by PSF deconvolution is validated on list mode MLEM reconstruction for DC-SPECT. A spatial invariant PSF is included as an additional test to show the influence of the accuracy of PSF modelling on the reconstructed image quality. We compare the MLEM reconstruction with and without PSF deconvolution; an analytic model is used for the calculation of system response, and the results are compared to Monte Carlo (MC) based methods. Results show that with PSF modelling applied, the quality of the reconstructed image is improved, and the DC-SPECT system can achieve a 4.5 mm central spatial resolution with average 795 counts/(s*Mbq). The results show substantial improvement over the gold standard GE Discovery 570c performance (spatial resolution 7 mm with an average 460 counts/s*MBq, central resolution 5.8 mm). The impact of PSF deconvolution is significant, and the improvements of the reconstructed image quality is more evident compared to MC simulated system matrix with the same sampling size as in simulation.
A Stereoselective Catalytic Nitroaldol Reaction as the Key Step in a Strategy for the Synthesis of the Renin Inhibitor Aliskiren (2015)

Abstract Aliskiren is the first‐in‐class orally active direct renin inhibitor. It was approved in 2007 for the treatment of hypertension. We have designed a new strategy for the convergent synthesis of aliskiren that involves a catalytic stereoselective nitroaldol reaction as the key step. A new enantiopure nitroalkane (synthon A 1 ), prepared in only three steps from a commercially available enantiopure 2‐(arylmethyl)‐3‐methyl butanol derivative, was successfully used in a copper‐catalysed Henry reaction to give a nitrolactone intermediate in which the correct configuration for the final product was established at all four stereocentres. Nitro‐group reduction, Boc‐protection of the resulting amine, aminolysis of the lactone with 3‐amino‐2,2‐dimethylpropionamide, and finally Boc‐deprotection led to the enantiopure renin inhibitor aliskiren.
Remarkable Reaction Rate and Excellent Enantioselective Direct α‐Amination of Aldehydes with Azodicarboxylates Catalyzed by Pyrrolidinylcamphor‐Derived Organocatalysts (2009)

Abstract Remarkable reaction rate and excellent enantioselective direct α‐amination of unmodified aldehydes with various azodicarboxylates was catalyzed by pyrrolidinylcamphor organocatalyst 2a (5 mol‐%) to provide the desired aminated products with excellent chemical yields and high to excellent levels of enantioselectivity (up to &gt;99 % ee ) at 0 °C in CH 2 Cl 2 .
Use of an Autologous Blood Recovery System during Emergency Pericardiocentesis in the Electrophysiology Laboratory (2008)

Autologous blood recovery during pericardiocentesis is safe, convenient, and feasible. With early use it may decrease or eliminate the need for allogeneic blood transfusion and, in selected cases, may permit completion of the ablation procedure.
High n-type Doping for Ge Lasers (2011)

An MDA Framework Supporting OCL (2024)

We present a model-driven architecture (MDA) framework that integrates formal analysis techniques into an industrial software development process model. This comprises modeling using UML/OCL, processing models by model transformations, code generation (including runtime-test environments) and formal analysis using the theorem proving environment HOL-OCL. Moreover, our frameworks supports the verification of proof obligations that are generated during model transformations. We show the extensibility of our approach by providing a SecureUML extension of the framework, which allows for an integrated specification of security properties, their analysis and their conversion to code.
Stereoelectronic control of the regioselectivity of both electrophilic and nucleophilic substitution of η6-(1,1-dimethylindane)tricarbonyl-chromium(0) (1982)

η 6 -(1,1-Dimethylindane)tricarbonylchromium(0) reacts with the nucleophile LiC(Me)2CN at C-5, a position eclipsed by a metal carbonyl bond in the preferred conformation of the molecule, and at C-6 and C-4, positions not eclipsed by metal carbonyl bonds with the electrophile MeCO+, confirming that stereoelectronic effects can dominate the regioselectivity of substitution of arenetricarbonylchromium complexes where the tricarbonyl-chromium unit adopts a highly preferred conformation.

Supporting End-User Debugging: What Do Users Want to Know? (2006)

Although researchers have begun to explicitly support end-user programmers' debugging by providing information to help them find bugs, there is little research addressing the right content to communicate to these users. The specific semantic content of these debugging communications matters because, if the users are not actually seeking the information the system is providing, they are not likely to attend to it. This paper reports a formative empirical study that sheds light on what end users actually want to know in the course of debugging a spreadsheet, given the availability of a set of interactive visual testing and debugging features. Our results provide in sights into end-user debuggers' information gaps, and further suggest opportunities to improve end-user debugging systems' support for the things end-user debuggers actually want to know.
Cytostatin, a novel inhibitor of cell adhesion to components of extracellular matrix produced by Streptomyces sp. MJ654-NF4. II. Physico-chemical properties and structure determination. (1994)

The structure of cytostatin was determined to be 5,6-dihydro-5-methyl-6-(6-hydroxy,1,5-dimethyl-4-phosphonooxy-7,9, 11-tridecatrienyl)-2H-pyran-2-one sodium salt on the basis of physico-chemical properties and NMR studies.
Generic Derivation of Dynamic Model for Half-Cycle DCM Series Resonant Converters (2017)

The series resonant converter (SRC) operated in the half-cycle discontinuous-conduction-mode (HC-DCM) provides galvanic separation and a tight coupling of its input and output voltages in an open-loop operation, i. e., with minimum control complexity, which renders it suitable for a wide range of applications that require galvanic isolation. This letter first explains the “DC transformer” behavior of the converter and then provides a generic derivation of a passive equivalent circuit that accurately models the converter's terminal behavior. The proposed generic derivation yields the known analytic results for idealized cases, but additionally allows for a parametrization of the equivalent circuit based on simulated or measured waveforms, thereby facilitating high accuracy also in nonideal cases. Furthermore, it is shown that a noninfinite magnetizing inductance results in an additional load-independent difference between the input and the output voltage, and a corresponding extension of the equivalent circuit model is proposed. The considerations are verified by simulations and measurements of a 10 kW/350 V/350 V HC-DCM SRC system.
DONOR ANTIGEN IS NECESSARY FOR THE PREVENTION OF CHRONIC REJECTION IN CTLA4IG-TREATED MURINE CARDIAC ALLOGRAFT RECIPIENTS1,2 (1997)

Donor cells are required to synergize with CTLA4Ig and prevent late cardiac allograft loss in the murine system. The fact that pretreatment of the donor cells alone is not effective suggests a role for antigen presentation by recipient antigen-presenting cells in the initiation of rejection. As lethal irradiation of the donor cells does not affect their ability to promote long-term engraftment, our data suggest that long-term microchimerism is not required to prevent chronic rejection in this model.
Mechanisms for Junction Degradation of Advanced MOSFETs Induced by Plasma Processing (2007)

MOSFETs with high-k gate stack (HfAlO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">x</sub> /SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> ) and those with SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> showed characteristic degradation induced by Ar-based electron cyclotron resonance (ECR) plasma, i.e., the increase in off-state leakage current (I <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Off</sub> ). The measurements of all source-to-drain current paths in MOSFETs revealed that the leakage through S/D-body junction was dominant. For both cases of the high-k gate stack and SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> , n-MOSFETs receive more severe damage than p-MOSFETs. It was found that difference of the gate leakage between high-k gate stack and SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> impacts on the junction degradation. C-V measurement identified that a root cause of the leakage increase is attributed to plasma-induced defect generation in the junction region.

FRAC: Implementing Role-Based Access Control for Network File Systems (2007)

We present FRAC, a Framework for role-based access control in network file systems. FRAC is a reference monitor that controls the message flow between file system clients and servers. FRAC supports role hierarchies, user sessions, and static and dynamic separation of duty constraints. It also allows administrators to define dynamic policies based on access history and the environment, e.g., time of day. FRAC introduces a virtual control namespace (VCN) that provides an interface to query and update the state of the access control framework over the standard file system protocol. This namespace eliminates the need for executing specialized user agents either at the client or at the server. Therefore, FRAC does not require any modification to either the file system client or the file server. We have implemented FRAC for the widely deployed NFS protocol using FileWall, a file system proxy previously developed by us. Our experimental evaluation shows that FRAC imposes minimal overheads for the common file system operations.
Production of advanced solid dispersions for enhanced bioavailability of itraconazole using KinetiSol® Dispersing (2010)

These results showed that production of amorphous solid dispersions containing concentration-enhancing polymers through KinetiSol Dispersing can provide improved oral bioavailability; however, additional formulation techniques must be developed to minimize variability associated with natural variations in subject gastrointestinal physiology.
The kinase DYRK1A phosphorylates the transcription factor FKHR at Ser329 in vitro, a novel in vivo phosphorylation site (2001)

Forkhead in rhabdomyosarcoma (FKHR) is a transcription factor that has been implicated in the control of gene expression by insulin, as well as the regulation of apoptosis by survival factors. These signals trigger the protein kinase B (PKB)-catalysed phosphorylation of FKHR at three residues (Thr(24), Ser(256) and Ser(319)) by a phosphoinositide 3-kinase-dependent pathway that results in the nuclear exit and inactivation of this transcription factor. Here, we have identified a conserved residue (Ser(329)) as a novel in vivo phosphorylation site on FKHR. Ser(329) phosphorylation also decreases the ability of FKHR to stimulate gene transactivation and reduces the proportion of FKHR present in the nucleus. However, unlike the residues targetted by PKB, Ser(329) is phosphorylated in unstimulated HEK-293 cells, and phosphorylation is not increased by stimulation with insulin-like growth factor-1 or by transfection with 3-phosphoinositide-dependent protein kinase-1. We have also purified a protein kinase to near homogeneity from rabbit skeletal muscle that phosphorylates FKHR at Ser(329) specifically and identified it as DYRK1A (dual-specificity tyrosine-phosphorylated and regulated kinase 1A). We find that FKHR and DYRK1A co-localize in discrete regions of the nucleus and can be co-immunoprecipitated from cell extracts. These experiments suggest that DYRK1A may phosphorylate FKHR at Ser(329) in vivo.
Switchable multicoil array for MR micro-imaging of breast lesions (1999)

High-resolution breast imaging may improve differentiation between benign and malignant lesions and may be important for refining treatment strategy. This article presents a new, flexible design of a breast-imaging coil capable of providing breast images of a high level of spatial resolution. Referred to as a switchable coil array, the design uses small-diameter surface coils that provide high sensitivity of detection, which, combined with a relatively small field of view, affords a high degree of spatial resolution (up to 200 microm). Remote selection of the coil pair closest to the position of the lesion in the breast permits coverage of the whole breast without changing the position of the coils or the patient. High-resolution MR images of phantom and volunteer patients with benign and malignant breast lesions are presented.
