Extraction of semantic biomedical relations from text using conditional random fields (2008)

We extend the framework of Conditional Random Fields towards the annotation of semantic relations from text and apply it to the biomedical domain. Our approach is based on a rich set of textual features and achieves a performance that is competitive to leading approaches. The model is quite general and can be extended to handle arbitrary biological entities and relation types. The resulting gene-disease network shows that the GeneRIF database provides a rich knowledge source for text mining. Current work is focused on improving the accuracy of detection of entities as well as entity boundaries, which will also greatly improve the relation extraction performance.

A Study on the Characteristics of Korean Web Novel Readers (2021)

이 글에서는 웹소설 독자와 문화가 서로 영향을 주고 받으면서 내적 규칙과 이념을 이루어왔다고 보고, 로맨스 웹소설 문화현상을 중심으로 로맨스 웹소설이라는 매체 혹은 장르의 특성과 이념을 밝히는 연구를 수행하였다. 웹소설 독자의 이념과 행동양식을 밝히기 위해 잠재 디리클레 할당기법과 문화비평에 대한 사회학적 접근법 중 이용과 충족이론을 활용하였다. 먼저 피서술자의 특성을 분석하여 웹소설 독자가 사랑에 대한 환상을 지니고 있으며 연애의 최종 목표가 결혼이라는 낭만적 사랑의 이념으로서의 핵가족 이데올로기를 지녔음을 밝혔다. 로맨스 웹소설 독자는 연애지상주의적인 생각을 공유하고 연애의 목적이 결혼임을 확인하는 동시에, 이를 즐기는 문화적 집단으로 간주된다. 아울러 댓글 분석을 중심으로 독자들에 의해 형성된 팬덤이 웹소설의 변화를 가로막고 있음도 살펴보았다. 도출된 결과를 통해 역으로 추적하면 로맨스 웹소설은 장르소설적이며, 컬트적 속성이 강한 대상으로 분석된다. 웹소설은 웹툰에 이어 한국 콘텐츠의 보고로 간주되고 있다. 새로운 이야기는 장르와 플롯이 뒤섞이는 과정에서 창출된다. 웹소설이 장르소설로서의 형태를 고수하는 한, 변화는 쉽지 않을 것으로 예측된다. 독자의 변화가 웹소설의 변화를 선도할 것이다.
The study of knee tibiofemoral condyle cartilage relaxation characters based on quantitative MR T2 imaging (2013)

Osteoarthritis (OA) is a degenerative joint disease that leads to the articular cartilage (AC) degeneration and joint function loss. Early stage OA is primarily associated with proteoglycan (PG) loss and collagen structure changes. The MR T2 imaging is a promising non-invasive diagnostic tool that has shown the potential to reflect changes in the biochemical composition of cartilage with early OA. T2 relaxation times give a quantitative measure of the molecular interactions occurring within the imaged cartilage tissues. It can represent cartilage tissue biochemical character that can be quantified with the help of specific imaging strategies. The goal of this study was to apply Levenberg-Marquardt curve fitting algorithm for T2 mapping quantification and T2 relaxation time calculation to study T2 relaxation characters based on quantitative MR T2 imaging of the tibiofemoral condyle cartilage. The MR T2 images of a healthy male volunteer's right knee were generated by a 3T MRI scanner using a spin echo multislice multiecho (MSME) Carr-Purcell Meiboom-Gill (CPMG) sequence. The medial and lateral tibiofemoral condyle cartilage was further subdivided into the regions of interest (ROIs) for identifying variation in T2 values. T2 relaxation times mean and standard deviation of ROIs were calculated using Levenberg-Marquardt curve fitting algorithm with correction and without correction. The results show that the Levenberg-Marquardt curve fitting algorithm was feasible for T2 relaxation time calculation of tibiofemoral cartilage, the CPMG sequence was sensitive to cartilage tissue imaging, and T2 parameter can be used for the characterization of articular cartilage tissue.
RDF Analysis of Radiation-Amorphized SiC using a field Emission Scanning Electron Microscope (1998)

Abstract Abstract Fast electrons are a particularly useful chemical and structural probe for the small sample volumes associated with ion- or fast electron-irradiation-induced amorphization, because of their much stronger interaction with matter than for X-rays or neutrons, and also because they can be readily focused to small probes. Three derivative signals are particularly rich in information: the angular distribution of scattered electrons (which is utilized in both diffraction and imaging studies); the energy loss spectrum of scattered electrons (electron energy loss spectroscopy, or EELS); and the emission spectrum of characteristic X-rays resulting from ionization energy losses (energy dispersive X-ray spectroscopy, or EDXS). We have applied the first two to the study of three amorphized compounds (AIPO4, SiO2, SiC) using MIT's Vacuum Generators HB603 field-emission (FEG) scanning transmission electron microscope (STEM), operating at 250 kV and equipped with a Gatan digital parallel-detection electron energy-loss spectrometer (digiPEELS).
Photoluminescence quenching in gold - MoS2 hybrid nanoflakes (2014)

Achieving tunability of two dimensional (2D) transition metal dichalcogenides (TMDs) functions calls for the introduction of hybrid 2D materials by means of localized interactions with zero dimensional (0D) materials. A metal-semiconductor interface, as in gold (Au) - molybdenum disulfide (MoS2), is of great interest from the standpoint of fundamental science as it constitutes an outstanding platform to investigate plasmonic-exciton interactions and charge transfer. The applied aspects of such systems introduce new options for electronics, photovoltaics, detectors, gas sensing, catalysis, and biosensing. Here we consider pristine MoS2 and study its interaction with Au nanoislands, resulting in local variations of photoluminescence (PL) associated with various Au-MoS2 hybrid configurations. By controllably depositing monolayers of Au on MoS2 to form Au nanostructures of given size and thickness, we investigate the electronic structure of the resulting hybrid systems. We present strong evidence of PL quenching of MoS2 as a result of charge transfer from MoS2 to Au: p-doping of MoS2. The results suggest new avenues for 2D nanoelectronics, active control of transport or catalytic properties.
A Demand Truncation and Migration Poisson Model for Real Demand Inference in Free-Floating Bike-Sharing System (2023)

The free-floating bike-sharing system enables users to pick up bikes from everywhere. However, the spatial-temporal imbalance of bikes becomes severer in such systems. Consequently, bikes are sometimes not available at desired location and time, and the pick-up demand of users is truncated. On demand truncation, the bike user would either give up using the bike or migrate to the nearby to pick up the bike. Thus, the demand of bikes observed from smart locks does not equate with the real demand. However, capturing the real demand is crucial for system planning and operation. Therefore, a statistical model, namely the demand truncation and migration Poisson (DTMP) model, is proposed to analyze the real demand. It is able to jointly model the real demand of FFBS and the migration behavior of users. In particular, we analyzed the demand truncation and migration processes to establish the relationship between the expected value of observed demand and that of real demand. Then, the real demand of using bikes was assumed to be related to the influential factors and the demand function was formulated. Subsequently, the likelihood for each observation was established. The performance of the proposed model was evaluated through field-testing data. The results revealed that the proposed DTMP model is superior to the baseline Poisson model from both the fitness and accuracy perspectives. Finally, the spatial-temporal distribution of the real demand and unmet demand of bikes in typical hours are presented. The results can guide the efficient management of the bike-sharing system.
Multiple-landmark routing for large groups in ad hoc networks (2003)

A typical scenario in mobile ad hoc networks (MANET) consists of nodes having functional and motorial affinities (e.g., tanks in the some battalion). In order to achieve scalability for such a network having a large scale, we introduce, in this paper, a novel "multiple-landmark" ad hoc routing protocol (M-LANMAR). The protocol is an "implicit", flexible hierarchical routing scheme following the traditional hierarchical method for handling scalability in large, wired networks. M-LANMAR features dynamic distributed election of multiple landmarks (with scope constraints) and destination discovery within each group using landmark forwarding mesh or multicast fabric techniques plus route caching. The scalability is achieved through efficiently handling the group motion patterns, namely, the truncation of local routing tables and the "summarization" of routing information to remote groups of nodes. Different from the previous proposed landmark ad hoc routing (LANMAR), M-LANMAR allows separate maintenance/optimization of user group size and local routing scope, leading to unrestricted group size regardless of local routing scope. The simulation results not only show election stability of the multiple landmarks but also confirm the good scalability properties of M-LANMAR in general ad hoc network infrastructures (networks that are large in size and/or that contain large logical groups).

Armature for Critical Infrastructures (2006)

Critical infrastructures have elevated requirements on security and availability. However, where security and availability are issues, security assurance evaluation becomes crucial. Evaluating security assurance is a non-trivial problem. In this paper, we discuss several security assurance aspects and the role of modeling in this context. We then introduce a novel, non-intrusive approach to security assurance evaluation. This approach comprises a modeling technique for the targeted infrastructure, the additional, non-intrusive evaluation infrastructure, and the implied evaluation methodology. We discuss possible implementations in an existing network.
Surgical Cavity Constriction and Local Progression Between Resection and Adjuvant Radiosurgery for Brain Metastases (2016)

Stereotactic radiosurgery (SRS) to a surgical cavity after brain metastasis resection is a promising treatment for improving local control. The optimal timing of adjuvant SRS, however, has yet to be determined. Changes in resection cavity volume and local progression in the interval between surgery and SRS are likely important factors in deciding when to proceed with adjuvant SRS. We conducted a retrospective review of patients with a brain metastasis treated with surgical resection followed by SRS to the resection cavity. Post-operative and pre-radiosurgery magnetic resonance imaging (MRI) was reviewed for evidence of cavity volume changes, amount of edema, and local tumor progression. Resection cavity volume and edema volume were measured using volumetric analysis. We identified 21 consecutive patients with a brain metastasis treated with surgical resection and radiosurgery to the resection cavity. Mean age was 57 yrs. The most common site of metastasis was the frontal lobe (38%), and the most common primary neoplasms were lung adenocarcinoma and melanoma (24% each). The mean postoperative resection cavity volume was 7.8 cm(3) and shrank to a mean of 4.5 cm(3) at the time of repeat imaging for radiosurgical planning (median 41 days after initial post-operative MRI), resulting in a mean reduction in cavity volume of 43%. Patients who underwent pre-SRS imaging within 1 month of their initial post-operative MRI had a mean volume reduction of 13% compared to 61% in those whose pre-SRS imaging was ≥1 month (p=0.0003). Post-resection edema volume was not related to volume reduction (p=0.59). During the interval between MRIs, 52% of patients showed evidence of tumor progression within the resection cavity wall. There was no significant difference in local recurrence if the interval between resection and radiosurgery was <1 month (n=8) versus ≥1 month (n=13, p=0.46). These data suggest that the surgical cavity after brain metastasis resection constricts over time with greater constriction seen in patients whose pre-SRS imaging is ≥1 month after initial post-operative imaging. Given that there was no difference in local recurrence rate, the data suggest there is benefit in waiting in order to treat a smaller resection cavity.
Planting Transgenic Insecticidal Corn Based on Economic Thresholds: Consequences for Integrated Pest Management and Insect Resistance Management (2006)

A simulation model of the western corn rootworm, Diabrotica virgifera virgifera LeConte, was used to investigate whether sampling and economic thresholds can improve integrated pest management (IPM) and insect resistance management (IRM) when transgenic insecticidal crops are used for insect pest management. When transgenic corn killed at least 80% of susceptible larvae, the calculated economic threshold increased linearly as the proportion of susceptible beetles surviving the toxin increased. The use of economic thresholds slightly slowed the evolution of resistance to transgenic insecticidal crops. In areas with or without rotation-resistant western corn rootworm phenotypes, the use of sampling and economic thresholds generated similar returns compared with strategies of planting transgenic corn, Zea mays L., every season. Because transgenic crops are extremely effective, farmers may be inclined to plant transgenic crops every season rather than implementing costly and time-consuming sampling protocols.
Adenocarcinoma In Situ of the Cervix-Controversies in Diagnosis and Treatment (2001)

Adenocarcinoma in situ (AIS) of the uterine cervix is a rare condition. Pap smear screening is unsatisfactory, and the disease has no morphologic reliable colposcopic features. Diagnosis is often made by chance during the treatment of squamous pre-invasive disease, which commonly coexists with AIS. Although the entire endocervical canal can be the site of disease, most lesions lie within 1 cm of the squamocolumnar junction. Skip lesions are rare, making fertility-sparing surgery a possibility under certain conditions. Recurrent disease occurs in 14% of cases when cone margins are free of disease and rise to more than 50% if the margins are involved. The method of conization is immaterial provided a large enough specimen is taken and that the endocervical margins can be evaluated by the pathologist. Follow-up of conservatively managed women is not defined; however, we recommend that regular endocervical cytology be performed in addition to conventional cytology and colposcopy.
Hybrid MacCormack-type Schemes for Computational Aeroacoustics (2015)

A new hybrid MacCormack-type scheme is presented, using a modified Low Dissipation and Dispersion Runge-Kutta time marching scheme. This new hybrid scheme has two stages in every step which use biased differencing stencils of the standard MacCormack-type scheme and for the remaining stages using the central differencing stencils. The resulting scheme has the inherent artificial dissipation of a MacCormack-type scheme while retaining the relative ease of boundary condition specification of a two-stage MacCormack scheme.
The Wnt/β-Catenin Signaling Pathway Tips the Balance Between Apoptosis and Reprograming of Cell Fusion Hybrids (2010)

Cell-cell fusion contributes to cell differentiation and developmental processes. We have previously showed that activation of Wnt/β-catenin enhances somatic cell reprograming after polyethylene glycol (PEG)-mediated fusion. Here, we show that neural stem cells and ESCs can fuse spontaneously in cocultures, although with very low efficiency (about 2%), as the hybrids undergo apoptosis. In contrast, when Wnt/β-catenin signaling is activated in ESCs and leads to accumulation of low amounts of β-catenin in the nucleus, activated ESCs can reprogram somatic cells with very high efficiency after spontaneous fusion. Furthermore, we also show that different levels of β-catenin accumulation in the ESC nuclei can modulate cell proliferation, although in our experimental setting, cell proliferation does not modulate the reprograming efficiency per se. Overall, the present study provides evidence that spontaneous fusion occurs, while the survival of the reprogramed clones is strictly dependent on induction of a Wnt-mediated reprograming pathway.
3DVIEWNIX: an open, transportable software system for the visualization and analysis of multidimensional, multimodality, multiparametric images (1993)

3DVIEWNIX, is a data-, machine-, and application-independent software system, developed and maintained on an ongoing basis by the Medical Image Processing Group. It is aimed at serving the needs of biomedical visualization researchers as well as biomedical end users. 3DVIEWNIX is not designed around a fixed methodology or a set of methods packaged in a fixed fashion for a fixed application. Instead, we have identified and incorporated in 3DVIEWNIX a set of basic imaging transforms that are required in most visualization, manipulation, and analysis methods. The result is a powerful exploratory environment that provides not only the commonly used standard tools but also an immense variety of others. In addition to visualization, it incorporates a variety of multidimensional structure manipulation and analysis methods. We have tried to make its design as much as possible image- dimensionality-independent to make it just as convenient to process 2D and 3D data as it is to process 4D data. It is based on UNIX, C, X-Window and our own multidimensional generalization of the 2D ACR-NEMA standards for image data representation.
EXHANCE‐12: 1‐year study of the exhalation delivery system with fluticasone (EDS‐FLU) in chronic rhinosinusitis (2018)

Over 1 year of treatment in CRS with and without NP, EDS-FLU 372 μg twice daily was well tolerated and produced improvements across a broad range of objective and subjective measures. EDS-FLU may be a desirable new option for patients with this condition.
Crystal Structure of Clostridium botulinum Whole Hemagglutinin Reveals a Huge Triskelion-shaped Molecular Complex (2013)

Clostridium botulinum HA is a component of the large botulinum neurotoxin complex and is critical for its oral toxicity. HA plays multiple roles in toxin penetration in the gastrointestinal tract, including protection from the digestive environment, binding to the intestinal mucosal surface, and disruption of the epithelial barrier. At least two properties of HA contribute to these roles: the sugar-binding activity and the barrier-disrupting activity that depends on E-cadherin binding of HA. HA consists of three different proteins, HA1, HA2, and HA3, whose structures have been partially solved and are made up mainly of β-strands. Here, we demonstrate structural and functional reconstitution of whole HA and present the complete structure of HA of serotype B determined by x-ray crystallography at 3.5 Å resolution. This structure reveals whole HA to be a huge triskelion-shaped molecule. Our results suggest that whole HA is functionally and structurally separable into two parts: HA1, involved in recognition of cell-surface carbohydrates, and HA2-HA3, involved in paracellular barrier disruption by E-cadherin binding.
Upper Eyelid Coloboma Repair Using Accessory Preauricular Cartilage in a Patient With Goldenhar Syndrome: Technique Revisited (2014)

We present an unusual case of upper eyelid coloboma repair in a patient with Goldenhar syndrome. We describe the use of a modified Cutler-Beard flap with concurrent inlay graft using cartilage from a preauricular appendage. This technique provides the benefits of autologous tissue, while minimizing donor site morbidity and reducing the risk of upper eyelid retraction.

Biosynthesis, Natural Sources, Dietary Intake, Pharmacokinetic Properties, and Biological Activities of Hydroxycinnamic Acids (2012)

Hydroxycinnamic acids are the most widely distributed phenolic acids in plants. Broadly speaking, they can be defined as compounds derived from cinnamic acid. They are present at high concentrations in many food products, including fruits, vegetables, tea, cocoa, and wine. A diet rich in hydroxycinnamic acids is thought to be associated with beneficial health effects such as a reduced risk of cardiovascular disease. The impact of hydroxycinnamic acids on health depends on their intake and pharmacokinetic properties. This review discusses their chemistry, biosynthesis, natural sources, dietary intake, and pharmacokinetic properties.
