A Software Defined Radio Application Utilizing Modern FPGAs and NoC Interconnects (2007)

Network on Chips are becoming a common onchip interconnect for both FPGA and mainstream processor designs. At the same time, software defined radios (SDR) are a new application field that is gaining much attention. As SDR tasks are mapped onto Network on Chip architectures, the typically streaming nature of samples will stress the NoC itself and possibly hurt the performance of other applications using that NoC. In this paper, we present the results of our partitioning and placement of a SDR transmitter onto a NoC architecture using an FPGA. We use a 802.11a transmitter example partitioned across a NoC and compare it to a handcrafted design. Additionally, various placement schemes, runtime architecture loads and NoC access methods are examined to determine the feasibility of this application and architecture combination.
The advanced glycation end product Nϵ‐carboxymethyllysine and its precursor glyoxal increase serotonin release from Caco‐2 cells (2017)

Advanced glycation end products (AGEs), comprising a highly diverse class of Maillard reaction compounds formed in vivo and during heating processes of foods, have been described in the progression of several degenerative conditions such as Alzheimer's disease and diabetes mellitus. N<sup>ϵ</sup> -Carboxymethyllysine (CML) represents a well-characterized AGE, which is frequently encountered in a Western diet and is known to mediate its cellular effects through binding to the receptor for AGEs (RAGE). As very little is known about the impact of exogenous CML and its precursor, glyoxal, on intestinal cells, a genome-wide screening using a customized microarray was conducted in fully differentiated Caco-2 cells. After verification of gene regulation by qPCR, functional assays on fatty acid uptake, glucose uptake, and serotonin release were performed. While only treatment with glyoxal showed a slight impact on fatty acid uptake (P < 0.05), both compounds reduced glucose uptake significantly, leading to values of 81.3% ± 22.8% (500 μM CML, control set to 100%) and 68.3% ± 20.9% (0.3 μM glyoxal). Treatment with 500 μM CML or 0.3 μM glyoxal increased serotonin release (P < 0.05) to 236% ± 111% and 264% ± 66%, respectively. Co-incubation with the RAGE antagonist FPS-ZM1 reduced CML-induced serotonin release by 34%, suggesting a RAGE-mediated mechanism. Similarly, co-incubation with the SGLT-1 inhibitor phloridzin attenuated serotonin release after CML treatment by 32%, hinting at a connection between CML-stimulated serotonin release and glucose uptake. Future studies need to elucidate whether the CML/glyoxal-induced serotonin release in enterocytes might stimulate serotonin-mediated intestinal motility.
48-Bit Integer Processing Beats 32-Bit Floating Point for Professional Audio: Applications (1999)

The emergence of new consumer formats for the delivery of digital audio into the home places ever more pressure on professional systems for maintaining the highest possible audio quality throughout the production process. For a while, it was thought that the 32-bit floating point processors provided a simple and adequate solution to the issues of dynamic range and scaling inherent in professional audio processing. It is clear now that even more precision is required to produce a finished product of 24-bit PCM at sampling rates of 96 KHz to 192 KHz. This paper discusses the differences between fixed point and floating point computation with respect to the audibility of computational error, and makes a case for the use of 48-bit integer processing as the standard by which professional systems should be measured. Floating-point has always been admired for its freedom from scaling and dynamic-range problems. It makes it possible to design digital filters without worrying about scaling problems in the state variables. Mixdown busses can be arbitrarily wide in terms of number of channels without fear of overflow. Since the 32-bit IEEE-752 floating point format allows 24 bits of mantissa (including the sign bit), it has been
Learning View-Disentangled Human Pose Representation by Contrastive Cross-View Mutual Information Maximization (2020)

We introduce a novel representation learning method to disentangle pose-dependent as well as view-dependent factors from 2D human poses. The method trains a network using cross-view mutual information maximization (CV-MIM) which maximizes mutual information of the same pose performed from different viewpoints in a contrastive learning manner. We further propose two regularization terms to ensure disentanglement and smoothness of the learned representations. The resulting pose representations can be used for cross-view action recognition. To evaluate the power of the learned representations, in addition to the conventional fully-supervised action recognition settings, we introduce a novel task called single-shot cross-view action recognition. This task trains models with actions from only one single viewpoint while models are evaluated on poses captured from all possible viewpoints. We evaluate the learned representations on standard benchmarks for action recognition, and show that (i) CV-MIM performs competitively compared with the state-of-the-art models in the fully-supervised scenarios; (ii) CV-MIM outperforms other competing methods by a large margin in the single-shot cross-view setting; (iii) and the learned representations can significantly boost the performance when reducing the amount of supervised training data.

Clinical Value of Routine Serum Squamous Cell Carcinoma Antigen in Follow-Up of Patients With Early-Stage Cervical Cancer (2001)

Serum SCC-ag analysis results in earlier recurrence detection in a small proportion (14%) of patients but did not contribute to better survival. As long as treatment possibilities for recurrent cervical cancer patients are not improved, serum SCC-ag analysis should not be carried out in routine follow-up.
Machine learning to guide clinical decision-making in abdominal surgery—a systematic literature review (2021)

A potential value of ML for surgical decision-making was demonstrated in several scientific articles. However, the low number of publications with only few collaborative studies between surgeons and computer scientists underpins the early phase of this highly promising field. Interdisciplinary research initiatives combining existing clinical datasets and emerging techniques of data processing may likely improve CDM in abdominal surgery in the future.
On the 2D Phase Retrieval Problem (2016)

The recovery of a signal from the magnitude of its Fourier transform, also known as phase retrieval, is of fundamental importance in many scientific fields. It is well known that due to the loss of Fourier phase the problem in one-dimensional (1D) is ill-posed. Without further constraints, there is no unique solution to the problem. In contrast, uniqueness up to trivial ambiguities very often exists in higher dimensions, with mild constraints on the input. In this paper, we focus on the 2D phase retrieval problem and provide insight into this uniqueness property by exploring the connection between the 2D and 1D formulations. In particular, we show that 2D phase retrieval can be cast as a 1D problem with additional constraints, which limit the solution space. We then prove that only one additional constraint is sufficient to reduce the many feasible solutions in the 1D setting to a unique solution for almost all signals. These results allow to obtain an analytical approach (with combinatorial complexity) to solve the 2D phase retrieval problem when it is unique.
<title>Performance of an experimental 8+-km wireless optical link in Tucson, Arizona</title> (2002)

Experiments were conducted during four days in January and February 2001 at Tucson AZ, to measure the performance of an optical wireless link between two telescopes 8.7 km apart. The transmission rate was OC-3 (155 Mbps) and the maximum total radiated power was 29 dBm. Extreme fluctuations in the received 1550-nm beam were observed, and these occasionally caused error bursts. The error bursts had frequencies (a maximum of 12 per hour) and durations (mostly &lt; 1 sec.) That were low enough to permit data transmission, e.g. via Ethernet TCP/IP. Fluctuations in the power of the 1550-nm received beam were positively correlated with variations in the elevation centroid. No correlations with meteorological measurements were found.
Extremum seeking methods for optimization of variable cam timing engine operation (2006)

Automotive engines have been increasingly equipped with devices that can vary engine parameters with operating conditions. Optimizing these parameters via standard engine mapping and calibration has become a very time consuming task. The specific problem under consideration in this paper is optimization of intake, exhaust, and spark timings to improve the brake specific fuel consumption of a dual-independent variable cam timing engine. We have explored extremum seeking (ES) as a method to find the optimal setting of the parameters. During ES, the engine is running at fixed speed and torque in a dynamometer test cell, while an optimization algorithm is iteratively adjusting the three parameters. For our purposes, we have modified several algorithms available in the literature. The details about the algorithms and the experimental results they produced are presented and discussed in the paper.
Development of High‐Acceleration Linear Motor to Realize Resource Saving and High Productivity (2017)

SUMMARY The use of linear motors has been rapidly increasing in recent years in response to the rising demand for drive mechanisms with higher speed and acceleration to improve the throughput of semiconductor production equipment, machine tools, and so on. In this study, we have developed a new type of linear motor with an opposed magnetic pole structure and twin movers. To achieve higher acceleration of a linear motor, it is necessary to satisfy both large thrust and low inertia. In our proposed new type linear motor, the thrust is improved by increasing the facing area between the permanent magnets and magnetic pole teeth by using multistage movers. Furthermore, the magnetic leakage flux is reduced by multiplexing the magnetic flux path. In a short stroke (approximately 210 mm) drive, the high acceleration of 1670 m/s 2 and maximum velocity of 14.2 m/s is demonstrated using a prototype linear motor (maximum thrust = 25 kN).
Induction and transient times in chemical reactions: Application to O2 dissociation (1976)

An analysis of relaxation phenomena in diatomic molecules, based on a harmonic oscillator master equation formalism, can accurately predict induction times for O2 dissociation in shock tubes, in the temperature range 2850° to 18 000°K, using measured vibrational relaxation times. In this case, the induction times are the direct result of relaxation of lower vibrational states prior to chemical reaction. Transient times for chemical reactions in temperature jump or shock tube experiments are shown to depend on the magnitude of the difference between initial and final temperatures. The phenomenological rate expression is valid for times greater than the transient times for large temperature jumps, and for practically all times for small temperature jumps.
Cellular Reprogramming Allows Generation of Autologous Hematopoietic Progenitors From AML Patients That Are Devoid of Patient-Specific Genomic Aberrations (2015)

Current treatments that use hematopoietic progenitor cell (HPC) transplantation in acute myeloid leukemia (AML) patients substantially reduce the risk of relapse, but are limited by the availability of immune compatible healthy HPCs. Although cellular reprogramming has the potential to provide a novel autologous source of HPCs for transplantation, the applicability of this technology toward the derivation of healthy autologous hematopoietic cells devoid of patient-specific leukemic aberrations from AML patients must first be evaluated. Here, we report the generation of human AML patient-specific hematopoietic progenitors that are capable of normal in vitro differentiation to myeloid lineages and are devoid of leukemia-associated aberration found in matched patient bone marrow. Skin fibroblasts were obtained from AML patients whose leukemic cells possessed a distinct, leukemia-associated aberration, and used to create AML patient-specific induced pluripotent stem cells (iPSCs). Through hematopoietic differentiation of AML patient iPSCs, coupled with cytogenetic interrogation, we reveal that AML patient-specific HPCs possess normal progenitor capacity and are devoid of leukemia-associated mutations. Importantly, in rare patient skin samples that give rise to mosaic fibroblast cultures that continue to carry leukemia-associated mutations; healthy hematopoietic progenitors can also be generated via reprogramming selection. Our findings provide the proof of principle that cellular reprogramming can be applied on a personalized basis to generate healthy HPCs from AML patients, and should further motivate advances toward creating transplantable hematopoietic stem cells for autologous AML therapy.
Cardiac Output Monitoring in Intensive Care Patients by Radial Artery Pressure Waveform Analysis (2005)

We have developed a novel technique for monitoring cardiac output (CO) changes by mathematically analyzing a single peripheral arterial blood pressure (ABP) waveform. In contrast to all previous techniques, our technique analyzes the ABP waveform over time scales greater than a cardiac cycle in which complex wave reflections are attenuated. We have previously validated the technique in swine instrumented with aortic flow probes. We present here an initial evaluation of the technique in 16 patient records of the MIMIC (Multi-parameter Intelligent Monitoring for Intensive Care) database, consisting of 122 simultaneous pairs of radial ABP waveforms and thermodilution CO. We report an overall error in the technique of 18.1% with respect to the error-prone clinical thermodilution measurements. This study promotes thorough future testing of the technique in humans.

Proposed refined diagnostic criteria and classification of eosinophil disorders and related syndromes (2022)

Eosinophilia and eosinophil activation are recurrent features in various reactive states and certain hematologic malignancies. In patients with hypereosinophilia (HE), HE-induced organ damage is often encountered and may lead to the diagnosis of a hypereosinophilic syndrome (HES). A number of known mechanisms and etiologies contribute to the development of HE and HES. Based on these etiologies and the origin of eosinophils, HE and HES are divided into primary forms where eosinophils are clonal cells, reactive forms where an underlying reactive or neoplastic condition is detected and eosinophils are considered to be "non-clonal" cells, and idiopathic HE and HES in which neither a clonal nor a reactive underlying pathology is detected. Since 2012, this classification and the related criteria have been widely accepted and regarded as standard. However, during the past few years, new developments in the field and an increasing number of markers and targets have created a need to update these criteria and the classification of HE and HES. To address this challenge, a Working Conference on eosinophil disorders was organized in 2021. In this conference, a panel of experts representing the relevant fields, including allergy, dermatology, hematology, immunology, laboratory medicine, and pathology, met and discussed new markers and concepts as well as refinements in definitions, criteria and classifications of HE and HES. The outcomes of this conference are presented in this article and should assist in the diagnosis and management of patients with HE and HES in daily practice and in the preparation and conduct of clinical trials.
Optical metrology terminal for satellite-to-satellite laser ranging (2019)

Interferometric laser ranging is an enabling technology for high-precision satellite-to-satellite tracking within the context of earth observation, gravitational wave detection, or formation flying. In orbit, the measurement system is affected by environmental influences, particularly satellite attitude jitter and temperature fluctuations, demanding an instrument design, which has a high level of thermal stability and is insensitive to rotations around the satellite's center of mass. Different design approaches for a heterodyne dynamic laser ranging instrument have been combined to a new improved design concept that involves the inherent beam tracking capabilities of a retroreflector into a mono-axial configuration with nanometer accuracy. In order to facilitate the accommodation onboard a future satellite mission, the design allows for a continuously adjustable flexible phase center position. To cover large inter-spacecraft distances, the instrument design comprises an active transponder system, featuring a two-dimensional beam steering mechanism to align a local, strong laser to the (weak) input beam without affecting the measurement path. To this end, a dynamic laser ranging instrument is presented, which has compact dimensions and is fully integrated on a single Zerodur baseplate. The instrument performance will be evaluated in a dedicated test setup providing a flat-top beam simulating the laser beam received from a distant spacecraft, including a beam steering subsystem, which allows for monitoring of pathlength variations when the angle of incidence at the optical instrument is changing.

High-performance bidirectional signalling in VLSI systems (1993)

Interchip I/O bandwidth is a critical bottleneck in VLSI systems. To make the best use of this resource the conventions and circuits used for inter-chip signaling must be optimized to achieve the maximum bit rate with minimumpower dissipation. This paper describes a set of I/O pads that we have developed at MIT. They operate with small signal levels to reduce power dissipation. To achieve high bandwidth, they operate simultaneously in both directions over a single wire and are isolated from supply noise. Bidirectional signalling is achieved by superimposing transmitted current waveforms and can be used with either transmission lines or lumped loads. This paper describes the theory behind our signaling method, the circuit design of the I/O transceivers, and the results of our experiments with prototype transceiver test chips. 1 Introduction As integrated circuit densities increase, the density and operating frequency of logic gates is growing at a much greater rate than that of chip I/...
