ALK positive anaplastic large cell lymphoma with a monomorphic small cell pattern masquerading as inflammatory gastric lesions.
Venue: The Malaysian journal of pathology
Year: 2019

Anaplastic lymphoma kinase positive (ALK+ anaplastic large cell lymphoma (ALCL) with a non common pattern can be diagnostic challenging. Pathologists can be unavoidably and unintentionally blind to non descript tumor cells in a lymphohistiocytic (LH) or small cell (SC) pattern. We report a case of primary systemic ALK+ ALCL with a SC pattern that presented as secondary gastric lesions with a mixed LH and SC pattern that was masqueraded as inflammatory lesions.  A 34 year old woman with intractable epigastric pain was referred to have repeated endoscopy with biopsy. She was found to multiple gastric erosions and nodules that were diagnosed as inflammatory lesions both endoscopically and histologically. Meanwhile, she developed an acute onset of severe back pain associated with a pathologic compression fracture in the T3 thoracic vertebral body. Imaging studies disclosed a disseminated systemic disease involving abdominopelvic lymph nodes and cervical and thoracic vertebral bodies. The needle biopsy of the pelvic lymph node disclosed diffuse proliferation of monomorphic small round cells that were diffusely positive for CD30 and ALK. A diagnosis of ALK+ ALCL with a monomorphic SC pattern was rendered.  A retrospective review of the gastric biopsies with the aid of immunohistochemistry enabled us to recognise the presence of lymphomatous infiltrates with a mixed LH and SC pattern in every piece of gastric biopsies that were repeatedly misdiagnosed as inflammatory lesions. This case illustrates a significant diagnostic pitfall of the LH and SC patterns in ALK+ ALCL, in which the tumour cells featuring lymphoid, plasmacytoid or histiocytoid appearance can be masqueraded as inflammatory cells.
The U.S. Health Care Crisis Continues: A Data Snapshot
Venue: International journal of health services planning, administration, evaluation
Year: 2018

Despite implementation of the Affordable Care Act in 2014, the U.S. health care crisis continues. While coverage has been expanded, 28 million people remain uninsured, and tens of millions who have coverage are unable to afford care because of high cost sharing requirements. Moreover, many with coverage have a sharply restricted choice of physicians and hospitals, and the corporate takeover of medical care in the United States is proceeding rapidly. This article provides a brief precis of recent data on U.S. health policy.
Moving Object Detection in Time Lapse or Motion Trigger Image Sequences Using Low Rank and Invariant Sparse Decomposition
Venue: 2017 IEEE International Conference on Computer Vision (ICCV)
Year: 2017

Low rank and sparse representation based methods have attracted wide attention in background subtraction and moving object detection, where moving objects in the scene are modeled as pixel wise sparse outliers. Since in real scenarios moving objects are also structurally sparse, recently researchers have attempted to extract moving objects using structured sparse outliers. Although existing methods with structured sparsity inducing norms produce promising results, they are still vulnerable to various illumination changes that frequently occur in real environments, specifically for time lapse image sequences where assumptions about sparsity between images such as group sparsity are not valid. In this paper, we first introduce a prior map obtained by illumination invariant representation of images. Next, we propose a low rank and invariant sparse decomposition using the prior map to detect moving objects under significant illumination changes. Experiments on challenging benchmark datasets demonstrate the superior performance of our proposed method under complex illumination changes.
Investigating Maternal Self Efficacy and Home Learning Environment of Families Enrolled in Head Start
Year: 2018

The aim of this study was to examine the relationships between mothers' self efficacy beliefs, their preschool children's home learning environments, and literacy skills. A sample of 112 mother child dyads was recruited from Head Start centers in rural and urban communities. The measures included maternal self efficacy and maternal perceptions of child's readiness to read as well as the Stipek Home Learning Activities (SHLA) scale, Home Learning Environment Profile (HLEP) and the Stony Brook Family Reading Survey (SBFRS) Modeling path analysis was performed. Model fit indices indicated that the resulting model was a good fit for the data. Concerning the direct effects of maternal self efficacy on home learning environment, positive significant effects for the SHLA measure as well as the HLEP were found. However, no direct effect was found with regard to maternal self efficacy on SBFRS indicating evidence for the domain specificity of efficacy beliefs. Implications of the study include findings that higher maternal self efficacy is related to creating a more positive home learning environment. Additionally, higher maternal perceptions of child readiness to read mediates the relationships between higher maternal self efficacy and a more positive home literacy environment. Moreover, these findings highlight the link between home learning environment and children's receptive vocabulary skills.
Opinion Mining from Online Reviews: Consumer Satisfaction Analysis with B&B Hotels
Venue: PACIS
Year: 2017

Given the enormous growth and significant impact of user generated content in online hotel reviews, this study aims to mining the determinants of consumer satisfaction with B&Bs and build a hierarchical structure of these determinants. Content analysis was conducted based on the consumer review data from two wellknown hotel booking websites. Ten determinants of customer satisfaction were identified. The interpretive structural modeling (ISM) technique was then used to develop a five level hierarchical structural model based on these determinants to illustrate the influencing paths. Finally, the cross impact matrix multiplication applied to classification (MICMAC) technique was used to analyze the driver and dependence power for each determinant. This study has the potential to make significant contributions from both the theoretical and practical perspectives in this research area.
Ethno knowledge and attitudes regarding snakebites in the Alto Jurua region, Western Brazilian Amazonia.
Venue: Toxicon official journal of the International Society on Toxinology
Year: 2019

The Alto Jurua region, located in the extreme western part of the Brazilian Amazonia, possesses an indigenous and riverine population which is involved in agricultural and forest extraction activities, and is a region that stands out for its high incidence of snakebites.  To assess the attitudes of the victims, the characteristics of the snakes and the circumstances of the snakebites which occurred in a region where human populations are highly exposed to snakes.  The study was conducted at the Regional Hospital of Jurua in the Municipality of Cruzeiro do Sul (Acre) which regularly attends victims of snakebites in the Alto Jurua region. The snakes that caused the envenomations were identified from clinical and epidemiological diagnosis of the symptoms and signs that patients presented during hospital, and by enzyme immunoassay for venom detection using serum samples of the patients, or by identification of the snake responsible for the envenomation when it was taken to the hospital or photographed. People who suffered or witnessed the snakebite were interviewed to assess the circumstances of the bite, the attitude adopted after the accident and whether they recognized the species of snake that caused the envenomation.  There were 133 cases of snakebite (76.24 100.000 inhabitants) mainly involving male individuals living in the rural area and who had a low level of education. The most affected groups were farmers (48% and children and teenagers (39% It was observed that 8.3% of them presented a history of recurrence for bites. The lower limbs were the most affected anatomical region (84% The Bothrops atrox snake, mainly small specimens (mostly juveniles) was the main species involved in the envenomations (83.4% Snakebites occurred mainly in forest areas, backyards of houses in rural areas and near to aquatic environments, during activities (walking, farming, extractivism, hunting) Most of the time, the snake was on the ground and the bite occurred because of the approximation of the individual, either by trampling or by approximation of a hand. Half of the victims performed some kind of inadequate first aid (not drinking water, use of tourniquet, incision at the site of the bite, use of black stone, drinking a compound " Snakebite is an important cause of morbidity in the Alto Jurua region. Bothrops bites are mostly caused by small sized specimens, probably due to the greater abundance of B. atrox juveniles, and also because small snakes are more difficult for people to see. People are more often bitten on the lower limbs probably due to the size of B. atrox (small and medium) and because the snakes are usually on the ground in most situations. Many victims resort to ineffective actions that can cause complications and also delay serotherapy. A low level of education is a factor that may contribute to worse outcomes in snakebites since it is associated with a lack of knowledge of preventive and first aid measures.
ANALISIS PENEMPATAN PENGATUR KECEPATAN MOTOR INDUKSI SATU FASA RUN KAPASITOR DENGAN MENGGUNAKAN TRIAC SEBAGAI PENGUBAH TEGANGAN
Year: 2015

Abstrak Motor induksi satu fasa run kapasitor merupakan motor yang sering diaplikasikan untuk keperluan industri maupun keperluan rumah tangga. Dalam penggunaanya seringkali memerlukan pengaturan kecepatan agar didapatkan kecepatan putar motor yang ideal dalam pengaplikasiannya. Untuk itu diperlukan pengaturan kecepatan motor yang tidak menyebabkan berbagai macam kerugian. Salah satu solusi pengaturan kecepatan tersebut adalah dengan Modul pengatur kecepatan menggunakan TRIAC sebagai pengatur tegangan, dan DIAC sebagai trigger.

Robust experimentation in the continuous time bandit problem
Year: 2020

We study the experimentation dynamics of a decision maker (DM) in a two armed bandit setup (Bolton and Harris in Econometrica 67(2):349 374, 1999) where the agent holds ambiguous beliefs regarding the distribution of the return process of one arm and is certain about the other one. The DM entertains Multiplier preferences a la Hansen and Sargent ( 2001) thus we frame the decision making environment as a two player differential game against nature in continuous time. We characterize the DM's value function and her optimal experimentation strategy that turns out to follow a cut off rule with respect to her belief process. The belief threshold for exploring the ambiguous arm is found in closed form and is shown to be increasing with respect to the ambiguity aversion index. We then study the effect of provision of an unambiguous information source about the ambiguous arm. Interestingly, we show that the exploration threshold rises unambiguously as a result of this new information source, thereby leading to more conservatism. This analysis also sheds light on the efficient time to reach for an expert opinion.
Dynamic Pooling and Unfolding Recursive Autoencoders for Paraphrase Detection
Venue: NIPS
Year: 2011

Paraphrase detection is the task of examining two sentences and determining whether they have the same meaning. In order to obtain high accuracy on this task, thorough syntactic and semantic analysis of the two statements is needed. We introduce a method for paraphrase detection based on recursive autoencoders (RAE) Our unsupervised RAEs are based on a novel unfolding objective and learn feature vectors for phrases in syntactic trees. These features are used to measure the word and phrase wise similarity between two sentences. Since sentences may be of arbitrary length, the resulting matrix of similarity measures is of variable size. We introduce a novel dynamic pooling layer which computes a fixed sized representation from the variable sized matrices. The pooled representation is then used as input to a classifier. Our method outperforms other state of the art approaches on the challenging MSRP paraphrase corpus.
Discovering and disambiguating named entities in text
Venue: SIGMOD'13 PhD Symposium
Year: 2013

Disambiguating named entities in natural language texts maps ambiguous names to canonical entities registered in a knowledge base such as DBpedia, Freebase, or YAGO. Knowing the specific entity is an important asset for several other tasks, e.g. entity based information retrieval or higher level information extraction. Our approach to named entity disambiguation makes use of several ingredients: the prior probability of an entity being mentioned, the similarity between the context of the mention in the text and an entity, as well as the coherence among the entities. Extending this method, we present a novel and highly efficient measure to compute the semantic coherence between entities. This measure is especially powerful for long tail entities or such entities that are not yet present in the knowledge base. Reliably identifying names in the input text that are not part of the knowledge base is the current focus of our work.
Abstract P4 15 11: Advanced HER2 positive breast cancer treated with trastuzumab: Is combination with chemotherapy always needed? Randomized phase III trial SAKK 22/99
Year: 2015

In advanced HER2+ breast cancer the impact of combining Trastuzumab (T) and chemotherapy (chemo) versus T alone followed by the addition of chemo at disease progression has not been properly studied.  The trial compared efficacy, toxicity and quality of life of sequential administration of T followed, at progression, by combination with chemo (T>TChemo) versus the upfront combination of T and chemo (TChemo) in patients with HER2+ advanced breast cancer.  ECOG performance status The estimated median TTP TChemo in the control arm (TChemo) was 5 6 months. A 3 months' increase in the experimental T>TChemo arm was considered meaningful. The chemo backbone was at investigator's choice (taxanes, vinorelbine, cisplatin) and could be stopped after 6 cycles in responding patients. T was continued until progression. Treatment after progression under TChemo was by investigators' decision. Patients' characteristics From Sept 1999 Jan 2013, 175 patients were enrolled. The trial was stopped prematurely due to insufficient accrual. Baseline characteristics were well balanced between arms: median age 55 years (32 79) ER and/or progesterone receptor positive 63% =2 disease sites 91% dominant bone 36% or dominant visceral disease 66% 1stline therapy 72%  At the cutoff date (May 2014) 173 patients were evaluable: median follow up 77.7 months, 29 patients (17% censored when receiving, at chemo stop, off protocol treatment before progression (maintenance metronomic chemotherapy or endocrine therapy) 11 patients (6% had no event at the end of follow up. TTP TChemo was longer than expected in both arms (12.7 months T>TChemo, 10.3 months TChemo) and not significantly different (HR=0.7; 95% CI, 0.5 1.0; p=0.08) In the T>TChemo arm, median TTP before introduction of chemo was 3.7 months (95% CI 2.3 5.1) Overall survival was not significantly different, 35.6 months versus 36.3 months (HR=0.9; 95% CI, 0.6 1.3; p=0.50) Toxicity was mainly chemo related, consistent with the chosen regimen. Cardiac toxicity was mild (no grade 4, 1 cardiac failure NYHA III in the T>TChemo arm) No treatment related death was reported.  The sequential administration of T and chemo showed a non significant trend to longer TTP TChemo compared to upfront combination therapy: it allows to delay chemo use and its toxicity and seems a reasonable approach. TTP TChemo was better than projected in both arms. The sequential strategy with double anti HER2 targeting (T/Pertuzumab) is now under evaluation in 1st line patients in the SAKK 22/10  Olivia Pagani, Dirk Klingbiel, Thomas Ruhstaller, Franco Nole, Serenella Eppenberger, Christian Oehlschlegel, Jurg Bernhard, Peter Brauchli, Dagmar Hess, Christoph Mamot, Elisabetta Munzone, Bernhard Pestalozzi, Manuela Rabaglio, Karin Ribi, Christoph Rochlitz, Karin Rothgiesser, Beat Thurlimann, Roger von Moos, Khalil Zaman, Aron Goldhirsch.

Design of silicon waveguides with all dielectric metamaterial cladding by employing numerical simulations
Venue: Photonics Europe
Year: 2020

Dense integration of photonic components in photonic integrated circuits presents an important challenge. To reduce the cross talk between the components and thus enable denser integration, sub wavelength all dielectric metamaterial claddings have been investigated. Such structures can be realized by patterning subwavelength ridges around the core of the integrated waveguide. In this contribution we present the results of analytical calculations and numerical simulations of optical systems with slab and strip waveguides with all dielectric metamaterial cladding and investigate the effects on evanescent field in the cladding. We show that a high refractive index contrast between the core and surrounding material is vital for the performance of all dielectric metamaterial claddings. In particular we include silicon, silicon oxide and silicon nitride materials in our investigation.
Few shot Relation Extraction via Bayesian Meta learning on Relation Graphs
Venue: ICML
Year: 2020

This paper studies few shot relation extraction, which aims at predicting the relation for a pair of entities in a sentence by training with a few labeled examples in each relation. To more effectively generalize to new relations, in this paper we study the relationships between different relations and propose to leverage a global relation graph. We propose a novel Bayesian meta learning approach to effectively learn the posterior distribution of the prototype vectors of relations, where the initial prior of the prototype vectors is parameterized with a graph neural network on the global relation graph. Moreover, to effectively optimize the posterior distribution of the prototype vectors, we propose to use the stochastic gradient Langevin dynamics, which is related to the MAML algorithm but is able to handle the uncertainty of the prototype vectors. The whole framework can be effectively and efficiently optimized in an end to end fashion. Experiments on two benchmark datasets prove the effectiveness of our proposed approach against competitive baselines in both the few shot and zero shot settings.
Acquisition du concept et des mots du temps chez l'enfant dyslexique
Year: 2014

Dans la pratique clinique orthophonique, il est souvent rapporte chez les enfants dyslexiques des troubles temporels. Ce domaine reste neanmoins peu explore. L'objectif de notre memoire est de confirmer l'existence de difficultes de comprehension du concept et des mots du temps chez l'enfant dyslexique. Nous avons donc soumis 20 enfants dyslexiques et 104 enfants tout venant scolarises du CP au CM2 a un protocole constitue du TKIC, outil d'evaluation de la connaissance du temps (Labrell et coll. 2014) et du QMT, questionnaire sur les mots du temps elabore par nos soins. Outre l'influence de la classe sur le developpement de la temporalite, les resultats montrent que les enfants dyslexiques presentent davantage de difficultes d'apprehension de la notion du temps ainsi qu'une comprehension verbo temporelle deficitaire, en particulier sur les mots du temps necessitant un raisonnement. Compte tenu du lien etroit entre le temps et le langage ecrit, le QMT une fois etalonne permettrait d'identifier precisement les aspects temporels a prendre en charge.
