Investigation of Orientation Dependence of the Thermal Expansion Coefficient in Silicon MEMS Resonators (2018)

The aim of this study is to investigate the behavior of the thermal expansion coefficient (CTE) of silicon at different crystallographic orientations through studies of the quality factor, Q, over a wide range of temperatures. We investigate how the observed effects of CTE may deviate from the expected isotropic behavior due to irregularities of fabrication, or because of the influence of doping or other effects.
[A Case of Giant Abdominal Desmoid Tumor in a Young Man]. (2023)

Desmoid tumor is a rare tumor of the soft tissue. The frequency of occurrence is 2.4 to 4.3 cases per year per million people, which is a very rare disease. We experienced a huge intra-abdominal desmoid tumor which is thought to be the primary mesentery. The case was a male in his 20s. He visited a nearby doctor with a complaint of abdominal bloating and abdominal pain. Abdominal contrast CT revealed a huge abdominal mass with a clear boundary of 35×25 cm in size extending from the upper right abdomen to the pelvis. Surgery was performed with a diagnosis of an intra-abdominal mass. Open abdominal tumor resection. Due to infiltration into the duodenum, transverse colon, and pancreas, right hemicolectomy and duodenal combined resection were performed. The pathological diagnosis was a diagnosis of desmoid tumor.
Repurposing Templates for Zeolite Synthesis from Simulations and Data Mining (2022)

Zeolites span a large variety of microporous crystal structures, making them useful materials for catalysis and separations. However, controlling phase competition in their synthesis often requires organic structure-directing agents (OSDAs) to selectively crystallize the desired topologies. Whereas computational design of OSDAs can help in selecting adequate candidates for zeolite synthesis, machine-generated templates are often complex or expensive. In this work, we use shape and binding metrics to propose templates for over 100 zeolites and to rationalize dual-OSDA approaches. Starting from OSDAs from the literature, promising templates were selected for zeolites ranging from clathrasil frameworks to extra large-pore structures. Selectivity maps derived from phase competition metrics show that small- and medium-pore zeolites tend to be more shape-selective toward their templates than their large-pore counterparts. Finally, shape and volume descriptors allow identification of OSDAs that may act as synergistic pore-fillers for different cavities of zeolites. The application of this theory is demonstrated for the case of the KFI zeolite, which may be synthesized using tetraethylammonium and OSDAs repurposed from high-silica LTA synthesis as dual OSDAs. This work may help in the discovery of new synthesis routes for known zeolites using shape descriptors and repurposed OSDAs.
FSS inspired polarization insensitive chipless RFID tag (2017)

A polarization insensitive, compact, fully-passive bit encoding structure exhibiting 1 : 1 resonator-to-bit correspondence is presented. Inspired by frequency selective surface (FSS) based microwave absorbers, the structure readily operates as a chipless radio frequency identification (RFID) tag. The unit cell is composed of several concentric hexagonal loops. Finite repetitions of the unit cell constitute the proposed RFID tag in its entirety. The required bit sequence is encoded in the frequency domain by addition or omission of corresponding nested resonant elements. A functional prototype is fabricated on a commercial-grade grounded FR4 substrate, occupying a physical footprint of 23 × 10 mm2 while offering a capacity of 14 bits. The proposed tag boasts a minuscule profile, and demonstrates polarization insensitivity as well as stable oblique angular performance.
Ultra-High Frequency Sound Waves for Microparticle Separation (2015)

In this study, we have demonstrated a particle separation device taking advantage of the ultra-high frequency sound waves. The sound waves, in the form of surface acoustic waves, are produced by an acoustofluidic platform build on top of a piezoelectric substrate bonded to a microfluidic channel. The particles’ mixture, pumped through the microchannel, is focused using a sheath fluid. A travelling surface acoustic wave (TSAW), propagating normal to the flow, interacts with the particles and deflect them from their original path to induce size-based separation in a continuous flow. We initially started the experiment with 40 MHz TSAWs for deflecting 10 μm diameter polystyrene particles but failed. However, larger diameter particles (∼ 30 μm) were successfully deflected from their streamlines and separated from the smaller particles (∼ 10 μm) using TSAWs with 40 MHz frequency. The separation of smaller diameter particles (3, 5 and 7 μm) was also achieved using an order of magnitude higher-frequency (∼ 133 MHz) TSAWs.

FP330ASSOCIATION BETWEEN WEIGHT REDUCTION AND DEVELOPING CARDIOVASCULAR EVENT AMONG THE GENERAL POPULATION (2018)

and RBCs (r -0.042; p 0.722), but a positive correlation was observed between MP-TF and platelets (r 0.237; p 0.042). CONCLUSIONS: PNs were elevated in ESRD patients, indicating an increased release of nucleosomes, suggesting increased cell death. The observed correlation between PNs and WBCs suggests that the detected PNs are derived from WBCs. A lack of correlation between PNs and MP-TF suggests that the MP-TF increase is independent of the pathophysiologic processes responsible for abnormal PN generation in ESRD patients.

Efficient Rectangular Maximal-Volume Algorithm for Rating Elicitation in Collaborative Filtering (2016)

Cold start problem in Collaborative Filtering can be solved by asking new users to rate a small seed set of representative items or by asking representative users to rate a new item. The question is how to build a seed set that can give enough preference information for making good recommendations. One of the most successful approaches, called Representative Based Matrix Factorization, is based on Maxvol algorithm. Unfortunately, this approach has one important limitation — a seed set of a particular size requires a rating matrix factorization of fixed rank that should coincide with that size. This is not necessarily optimal in the general case. In the current paper, we introduce a fast algorithm for an analytical generalization of this approach that we call Rectangular Maxvol. It allows the rank of factorization to be lower than the required size of the seed set. Moreover, the paper includes the theoretical analysis of the method's error, the complexity analysis of the existing methods and the comparison to the state-of-the-art approaches.

Susceptor-Based Rapid Thermal Processing System and Its Silicide Application (1998)

The design concept and hardware configuration of a constant heat source, susceptor-based dual wafer rapid thermal processing (RTP) system are described. The temperature measurement/control techniques and thermal characteristics of the RTP system are described. Typical process results in CoSi and TiSi formation using the RTP system are reported. Change in sheet resistance uniformity before and after RTP steps and wafer-to-wafer temperature repeatability were kept below 0.5% and 1°C, respectively, in both processes. Due to the dual wafer process capability and steady state temperature control, a very high throughput at a minimal power consumption was realized. Many thermal processes used in furnaces can easily be converted to RTP processes without decreasing cost performance and/or deteriorating process results by using the RTP system.
Rapid Formation of Dibutylstannylene Acetals from Polyhydroxylated Compounds under Microwave Heating. Application to the Regioselective Protection of Polyols and to a Catalytic Tin-mediated Benzoylation (1994)

The formation of dibutylstannylene acetals from polyols and dibutyltin oxide is accelerated under microwave heating. The method is applied to the regioselective benzoylation of a variety of polyols. Some preliminary results on a catalytic tin-mediated benzoylation of polyols are also presented.
Leveraging walking inertial pattern for terrain classification (2020)

The goal of this work is to illustrate how measurements collected during walking by inertial sensors embedded in the shoes' sole can be used to reveal the underlying terrain type. The final aim is to enable the automatic, real time adaptation of the actuated bottom cushioning of the innovative Wahu shoe for the sake of safety and comfort. For this purpose, the gait patterns of the normal walk of different healthy subjects on four different surface types, with different hardness and friction, are collected offline and represented through the three accelerations' time history. These signals are pre-processed and segmented into two different “elementary” items, a “walk” object, made of a sequence of subsequent steps, and a “mean step” object. In both cases, time and frequency attributes are computed and the most explicative selected through a principal component analysis. A cubic SVM classifier is then trained with the experimental data from multiple walking trials and its performance investigated on different validation sets. Confusion matrices show that the complete “walk” segment performs much better in terms of prediction power and this is encouraging for further development of the methodology in real time.
Unsupervised Visual and Textual Information Fusion in CBMIR Using Graph-Based Methods (2015)

Multimedia collections are more than ever growing in size and diversity. Effective multimedia retrieval systems are thus critical to access these datasets from the end-user perspective and in a scalable way. We are interested in repositories of image/text multimedia objects and we study multimodal information fusion techniques in the context of content-based multimedia information retrieval. We focus on graph-based methods, which have proven to provide state-of-the-art performances. We particularly examine two such methods: cross-media similarities and random-walk-based scores. From a theoretical viewpoint, we propose a unifying graph-based framework, which encompasses the two aforementioned approaches. Our proposal allows us to highlight the core features one should consider when using a graph-based technique for the combination of visual and textual information. We compare cross-media and random-walk-based results using three different real-world datasets. From a practical standpoint, our extended empirical analyses allow us to provide insights and guidelines about the use of graph-based methods for multimodal information fusion in content-based multimedia information retrieval.
Measurements of focused, finite amplitude sound beams reflected from curved targets (1993)

The reflection of focused, finite amplitude sound beams from curved targets in water was investigated experimentally and theoretically. Measurements of small signal diffraction effects were used to characterize the effective radius (1.9 cm) and focal length (15 cm) of the source, the center frequency of which is 2.25 MHz. Detailed comparisons are made between measurements of harmonic generation in the incident focused beam and numerical results from a computer code that solves the KZK equation in the frequency domain [Naze Tjo/tta etal., J. Acoust. Soc. Am. 89, 1017–1027 (1991)]. Reflection from both convex and concave target surfaces is considered. The targets are made of nickel with different radii of curvature down to a minimum of 5 cm. Measurements of the reflected beam were obtained with a membrane hydrophone that was placed between the source and the target. Theoretical predictions for harmonic generation in the reflected field were obtained by modifying the computer code to account for the phase shifts introduced by interaction of the incident beam with the target. Theory and experiment are in good agreement for both the incident and reflected beams. [Work supported by the Packard Foundation and the Office of Naval Research.]
New Therapeutic Frontiers for Metabotropic Glutamate Receptors (2005)

Our understanding of glutamatergic transmission in the central nervous system has been greatly expanded with the discovery and investigation of the metabotropic glutamate receptor family. Complementing the ionotropic glutamate-gated ion channels, these G-protein coupled receptors play critical roles in neuronal and glial functions such as the modulation of neuronal excitability, synaptic transmission, and various metabolic functions. Because of the ubiquitous distribution of glutamatergic synapses, it has been deemed likely that mGlu receptors participate in most, if not all, major functions of the CNS. It is predicted that the wide diversity and heterogeneous distribution of mGlu receptor subtypes will provide avenues to develop clinically relevant pharmacological agents that target specific CNS systems. mGlu receptors are regulated by differences in expression, alternative splicing patterns, and interactions with other proteins in the cell and it is anticipated that an understanding of these modifiers of mGlu receptor function will open new opportunities for pharmacological tool development and new therapeutic strategies. Over the past decade, an increasing number of selective agonists, antagonists, and allosteric modulators have been developed which target distinct mGlu receptor subtypes; many of these agents have now been further validated in numerous electrophysiological and behavioral models. The combination of these pharmacological tools, in conjunction with genetic approaches, has led to major advances in our understanding of the roles of mGlu receptors in the regulation of CNS function and animal behavior. These studies suggest the exciting possibility that drugs active at mGlu receptors will be useful in treatment of a wide variety of neurological and psychiatric disorders such as Parkinson's disease, anxiety disorders, and schizophrenia.

Fully monolithically integrated X-band power amplifier without external matching (2010)

In this paper a fully monolithically integrated power amplifier for X-band is presented. The push-pull amplifier uses an on-chip transformer for input matching, an autotransformer with capacitive divider for interstage matching, and an LC-balun for output matching. It does not require any external matching circuits. The power amplifier is implemented in a 0.35 µm SiGe bipolar technology. At 10 GHz operating frequency and a supply voltage of 1.5 V the amplifier achieves maximum power added efficiency greater than 30%, gain 23 dB, and maximum output power greater than 23 dBm.
Photo recall (2014)

We describe a system for searching your personal photos using an extremely wide range of text queries, including dates and holidays ("Halloween"), named and categorical places ("Empire State Building" or "park"), events and occasions ("Radiohead concert" or "wedding"), activities ("skiing"), object categories ("whales"), attributes ("outdoors"), and object instances ("Mona Lisa"), and any combination of these -- all with no manual labeling required. We accomplish this by correlating information in your photos -- the timestamps, GPS locations, and image pixels -- to information mined from the Internet. This includes matching dates to holidays listed on Wikipedia, GPS coordinates to places listed on Wikimapia, places and dates to find named events using Google, visual categories using classifiers either pre-trained on ImageNet or trained on-the-fly using results from Google Image Search, and object instances using interest point-based matching, again using results from Google Images. We tie all of these disparate sources of information together in a unified way, allowing for fast and accurate searches using whatever information you remember about a photo.
Estimation of distortion sensitivity for visual quality prediction using a convolutional neural network (2018)

The PSNR and MSE are the computationally simplest and thus most widely used measures for image quality, although they correlate only poorly with perceived visual quality. More accurate quality models that rely on processing on both the reference and distorted image are potentially difficult to integrate in time-critical communication systems where computational complexity is disadvantageous. This paper derives the concept of distortion sensitivity as a property of the reference image that compensates for a given computational quality model a potential lack of perceptual relevance. This compensation method is applied to the PSNR and leads to a local weighting scheme for the MSE. Local weights are estimated by a deep convolutional neural network and used to improve the PSNR in a computationally graceful distribution of computationally complex processing to the reference image only. The performance of the proposed estimation approach is evaluated on LIVE, TID2013 and CSIQ databases and shows comparable or superior performance compared to benchmark image quality measures.
Structural Basis of Compound Recognition by Adenosine Deaminase (2005)

Structural snapshots corresponding to various states enable elucidation of the molecular recognition mechanism of enzymes. Adenosine deaminase has two distinct conformations, an open form and a closed form, although it has so far been unclear what factors influence adaptation of the alternative conformations. Herein, we have determined the first nonligated structure as an initial state, which was the open form, and have thereby rationally deduced the molecular recognition mechanism. Inspection of the active site in the nonligated and ligated states indicated that occupancy at one of the water-binding positions in the nonligated state was highly significant in determining alternate conformations. When this position is empty, subsequent movement of Phe65 toward the space induces the closed form. On the other hand, while occupied, the overall conformation remains in the open form. This structural understanding should greatly assist structure-oriented drug design and enable control of the enzymatic activity.
CoBayes (2011)

Our work aims at building probabilistic tools for constructing and maintaining large-scale knowledge bases containing entity-relationship-entity triples (statements) extracted from the Web. In order to mitigate the uncertainty inherent in information extraction and integration we propose leveraging the "wisdom of the crowds" by aggregating truth assessments that users provide about statements. The suggested method, CoBayes, operates on a collection of statements, a set of deduction rules (e.g. transitivity), a set of users, and a set of truth assessments of users about statements. We propose a joint probabilistic model of the truth values of statements and the expertise of users for assessing statements. The truth values of statements are interconnected through derivations based on the deduction rules. The correctness of a user's assessment for a given statement is modeled by linear mappings from user descriptions and statement descriptions into a common latent knowledge space where the inner product between user and statement vectors determines the probability that the user assessment for that statement will be correct. Bayesian inference in this complex graphical model is performed using mixed variational and expectation propagation message passing. We demonstrate the viability of CoBayes in comparison to other approaches, on realworld datasets and user feedback collected from Amazon Mechanical Turk.

In vitro Evidence of Human Immune Responsiveness Shows the Improved Potential of a Recombinant BCG Strain for Bladder Cancer Treatment (2019)

The live attenuated mycobacterial strain BCG, in use as vaccine against tuberculosis, is considered the gold standard for primary therapy of carcinoma <i>in situ</i> of the bladder. Despite its limitations, to date it has not been surpassed by any other treatment. Our group has developed a recombinant BCG strain expressing the detoxified S1 pertussis toxin (rBCG-S1PT) that proved more effective than wild type BCG (WT-BCG) in increasing survival time in an experimental mouse model of bladder cancer, due to the well-known adjuvant properties of pertussis toxin. Here, we investigated the capacity of rBCG-S1PT to stimulate human immune responses, in comparison to WT-BCG, using an <i>in vitro</i> stimulation assay based on human whole blood cells that allows for a comprehensive evaluation of leukocyte activation. Blood leukocytes stimulated with rBCG-S1PT produced increased levels of IL-6, IL-8, and IL-10 as compared to WT-BCG, but comparable levels of IL-1β, IL-2, IFN-γ, and TNF-α. Stimulation of blood cells with the recombinant BCG strain also enhanced the expression of CD25 and CD69 on human CD4<sup>+</sup> T cells. PBMC stimulated with rBCG-S1PT induced higher cytotoxicity to MB49 bladder cancer cells than WT-BCG-stimulated PBMC. These results suggest that the rBCG-S1PT strain is able to activate an immune response in human leukocytes that is higher than that induced by WT-BCG for parameters linked to better prognosis in bladder cancer (regulation of immune and early inflammatory responses), while fully comparable to WT-BCG for classical inflammatory parameters. This establishes rBCG-S1PT as a new highly effective candidate as immunotherapeutic agent against bladder cancer.
HiperLAN 5.4-GHz low-power CMOS synchronous oscillator (2001)

A 5.4-GHz 0.25-/spl mu/m very-large-scale-integration CMOS synchronous oscillator (SO) is proposed in this paper, which is designed to act as a local oscillator for HiperLAN systems. The advantage of using such an oscillator in a double-loop frequency synthesizer is demonstrated. The design strategy leading to an optimized SO with regards to its synchronization range is described. A test chip is presented, which provides a 150-MHz synchronization range and a -97-dBc/Hz phase noise at 10-kHz offset from the 5-GHz carrier, while consuming only 5 mA from a 2.5-V supply.
