20-Gb/s QPSK W-band (75-110GHz) wireless link in free space using radio-over-fiber technique (2011)

We demonstrate 20-Gb/s W-band wireless transmission in free space with a distance of 30mm using optical signal generation. Optically synthesized QPSK signal and direct optical upconversion technique ease generation of W-band RoF signals for dual purpose of wireline and wireless transmission link. A W-band radio receiver with W-band frequency downconversion and digital signal processing will be applicable for any W-band radio detection.
Combining Hand-crafted Rules and Unsupervised Learning in Constraint-based Morphological Disambiguation (1996)

This paper presents a constraint-based morphological disambiguation approach that is applicable languages with complex morphology--specifically agglutinative languages with productive inflectional and derivational morphological phenomena. In certain respects, our approach has been motivated by Brill's recent work, but with the observation that his transformational approach is not directly applicable to languages like Turkish. Our system combines corpus independent hand-crafted constraint rules, constraint rules that are learned via unsupervised learning from a training corpus, and additional statistical information from the corpus to be morphologically disambiguated. The hand-crafted rules are linguistically motivated and tuned to improve precision without sacrificing recall. The unsupervised learning process produces two sets of rules: (i) choose rules which choose morphological parses of a lexical item satisfying constraint effectively discarding other parses, and (ii) delete rules, which delete parses satisfying a constraint. Our approach also uses a novel approach to unknown word processing by employing a secondary morphological processor which recovers any relevant inflectional and derivational information from a lexical item whose root is unknown. With this approach, well below 1 percent of the tokens remains as unknown in the texts we have experimented with. Our results indicate that by combining these hand-crafted,statistical and learned information sources, we can attain a recall of 96 to 97 percent with a corresponding precision of 93 to 94 percent, and ambiguity of 1.02 to 1.03 parses per token.
Interstitial lymphangiography: initial clinical experience with a dimeric nonionic contrast agent. (1989)

Interstitial lymphangiography performed with intradermal injection of a new nonionic dimeric contrast agent was used to examine 34 normal lower extremities and 35 lower extremities with proved lymphedema. An infusion pump was used to inject 2 mL of the contrast agent into the intradermal interdigital space at a rate of 0.1 mL/min. In all normal extremities, the injection deposit appeared homogeneous, and one to five lymph vessels could be identified. Diffusion of contrast agent into perilymphatic tissue occurred 30-40 cm proximal to the injection site; inguinal lymph nodes were, therefore, not routinely visualized. The findings at interstitial lymphangiography were abnormal in all extremities with advanced lymphedema. The results indicate that interstitial lymphangiography with the use of a nonionic dimeric contrast agent allows morphologic assessment of lymphatic vessels and facilitates the diagnosis of lymphatic obstructive disease.
Virtual cathode oscillator under various cathode radii with intense relativistic electron beam (2002)

It has been reported that the virtual cathode is formed when the electron beam current in the drift region exceeds the space charge limiting current. In this study, the axially extracted virtual cathode oscillator (vircator), which is new conceptual device and the ultra-high power (/spl sim/GW) microwave generator, with "chundoong" intense relativistic electron beam pulser (max. 600 kV, 70 kA, 60 ns) has been constructed. The virtual cathode formation has been numerically simulated by 2-1/2 dimensional PIC code "MAGIC", from which the dominant frequency and the extracted power have been evaluated before the experiment. In experiments, the incident current density into drift tube was measured to be about 0.6 kA/cm/sup 2/ under the diode voltage and the A-K gap were kept to be 300 kV and 4 mm respectively. Maximum power of extracted microwave is about 520 MW and its conversion efficiency is about 9% under cathode radius of 2.5 cm. It has been also found that the propagating microwave mode is the combination of TM/sub 01/ and the other higher mode based on the electric field (Ez) profile versus cathode radius. The dominant microwave frequency is shown to be 5/spl square/7 GHz from this experiment.

Cross layer design for multimedia streaming over wireless 802.11e networks (2011)

WLAN (Wireless Local Area Networks) is becoming popular in all kinds of data communications. Providing Quality of Service (QoS) especially for bandwidth intense, delay sensitive realtime multimedia traffic over WLAN is a challenge. In most presented work about providing QoS in wireless, the QoS for realtime traffic is achieved at the cost of best effort traffic. This paper presents a cross-layer design to provide QoS to both realtime traffic and best effort traffic over 802.11e networks. The proposed mechanism considers co-design of the Application and MAC layers in 802.11e networks. An interface is designed to tune MAC layer parameters based on the information from application layer. Simulations and performance analysis show our proposed mechanism not only provides QoS to multimedia traffic but also lets non-realtime users receive the maximum possible throughput. Thus, a mixture of realtime and non-realtime users can be supported simultaneously.
CorpusVis: Visual Analysis of Digital Sheet Music Collections (2022)

Manually investigating sheet music collections is challenging for music analysts due to the magnitude and complexity of underlying features, structures, and contextual information. However, applying sophisticated algorithmic methods would require advanced technical expertise that analysts do not necessarily have. Bridging this gap, we contribute CorpusVis, an interactive visual workspace, enabling scalable and multi-faceted analysis. Our proposed visual analytics dashboard provides access to computational methods, generating varying perspectives on the same data. The proposed application uses metadata including composers, type, epoch, and low-level features, such as pitch, melody, and rhythm. To evaluate our approach, we conducted a pair analytics study with nine participants. The qualitative results show that CorpusVis supports users in performing exploratory and confirmatory analysis, leading them to new insights and findings. In addition, based on three exemplary workflows, we demonstrate how to apply our approach to different tasks, such as exploring musical features or comparing composers.

363-OR: Comprehensive Assessment of Glycemic Control after Pancreas Transplantation (2020)

Introduction: Limited data are available about comprehensive metabolic evaluation after Pancreas transplantation (PT) for type 1 diabetes (T1D). Methods: After IRB approval, we prospectively studied 15 PT recipients at least 1 year post transplant. After a screening visit, subjects underwent Dexcom G4 CGM for one week and Mixed Meal Test (MMT) according to standard procedure. Results: PT recipient were 53.1 ± 10.6 years old, F/M 12/3, BMI (Kg/m2) 30.8 ± 6 and mean duration of diabetes was 33 ± 12.3 years with 6 ± 5 (1-17) years mean interval from PT to the study. Twelve patients underwent pancreas transplant alone and three underwent simultaneous pancreas kidney transplantation. Baseline values were Hemoglobin 12.3 ± 1.4 (g/dl), HbA1c 5.4 ± 0.6 %, Albumin 4.0 ± 0.3 g/dl, Fructosamine 233 ± 27 (µmol/L), Fasting Glucose 94.3 ± 17.5 mg/dl, C-peptide 2.5 ± 0.9 (ng/ml), eGFR 56.3 ± 25.5 ml/min and AST 23.4 ± 8.5 U/L. MMT revealed Glucose concentration increased from 90.9 ± 9.6 mg/dl at baseline to 140.6 ± 41.5 mg/dl at 30min followed by 123.2 ± 48.0 mg/dl and 115.2 ± 34.6 mg/dl at 60mins and 120 mins respectively. C-peptide was 2.4 ± 0.7 ng/ml at baseline, peaked to 7.5 ± 5.4 ng/ml at 60 mins and was 6.0 ± 3.6 mins and 5.9 ± 2.4 at 30 and 120 mins respectively with insulin peaking from 13.5 ± 5.5 uIU/ml at baseline to 107 ± 81.6 uIU/ml at 30 mins and 85.8 ± 78 uIU/ml and 42.2 ± 23.2 uIU/ml at 60 mins and 120 mins respectively. CGM analysis revealed mean CGM glucose was 120.4 ± 14.8 with SD 26.2 ± 7.7. Glucose control was excellent with 94 ± 9.2% of readings within 70-180mg/dl and 79.8 ± 17.6% within 70-140 mg/dl. Percentage time &amp;lt; 70 mg/dl and &amp;lt; 54 mg/dl were 1.1 ± 1.1% and 0.1 ± 0.4% respectively. Percentage time &amp;gt; 180 and &amp;gt; 250 mg/dl were 4.8 ± 9.3% and 0.4 ± 0.7% respectively. HBGI, LBGI and ADRR were 1.3 ± 1.6, 0.7 ± 0.5 and 17.4 ± 8.9 respectively. Conclusion: PT recipients demonstrate excellent glucose control on comprehensive assessment one or more years after the procedure. CGM and MMT data are different from normal people. Disclosure R.

Notes on LINPACK NxN Benchmark on Hewlett-Packard Systems (2001)

Here is the original description of the NxN benchmark [2]: ”[...] The ground rules are as follows: Solve systems of linear equations by some method, allow the size of the problem to vary, and measure the execution time for each size problem. In computing the floating-point execution rate, use 2n/3 + 2n operations independent of the actual method used. (If you choose to do Gaussian Elimination, partial pivoting must be used.) Compute and report a residual for the accuracy of solution as ‖Ax− b‖/(‖A‖‖x‖). The columns in Table 3 are defined as follows: Rmax the performance in Gflop/s for the largest problem run on a machine. Nmax the size of the largest problem run on a machine. N1/2 the size where half the Rmax execution rate is achieved. Rpeak the theoretical peak performance Gflop/s for the machine. [...]”

A System-Identification-Error-Robust Method for equalization of multichannel acoustic systems (2010)

In hands-free communications, speech received by a microphone is distorted by room reverberation that can reduce the intelligibility of speech. An approach to dereverberation is firstly to estimate the impulse responses of the acoustic channels between the speaker and the microphones and secondly to design a multichannel equalization system based on the estimated impulse responses. Traditional equalization techniques are designed without the consideration of estimation errors that are commonly introduced by the system identification process. In this work, a System-Identification-Error-Robust Equalization Method (SIEREM) for the equalization of multichannel room acoustic systems is presented. Experimental results for dereverberation using SIEREM applied to estimates of single-input multiple-output acoustic systems with known level of estimation errors show that the proposed equalization design significantly outperforms existing methods in the presence of both synthetic and real system identification errors.
Longitudinal Vibration Modeling and Control of a Flexible Transporter System with Arbitrarily Varying Cable Lengths (2005)

We present a systematic procedure for deriving the model of a cable transporter system with arbitrarily varying cable lengths. The Hamilton principle is applied to derive the governing equations of motion. The derived governing equations are nonlinear partial differential equations. The results are verified using the Newton law. The assumed mode method is used to obtain an approximate numerical solution of the governing equations by transforming the infinite-dimensional partial differential equations into a finite-dimensional discretized system. We propose a Lyapunov controller, based directly on the governing partial differential equations, which can both dissipate the vibratory energy during the motion of the transporter and guarantee the attainment of the desired goal point. The validity of the proposed controller is verified by numerical simulation.
Transparent driving thin-film transistor circuits based on uniformly grown single-walled carbon nanotubes network (2009)

Optically transparent and mechanically flexible thin-film transistors have recently attracted attention for next generation transparent display technologies. Driving and switching transistors for transparent displays have challenging requirements such as high optical transparency, large-scale integration, suitable drive current (I <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">on</sub> ) in ¿A range, high on/off current ratio (I <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">on</sub> /I <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">off</sub> ), high field effect mobility, and uniform threshold voltage(Vt). In this study, we demonstrate fully-transparent high-performance and high-yield thin film transistors based on random growth of single-walled carbon nanotube (SWNT) network that are easy to fabricate., These SWNT-based transparent thin film transistors show excellent electrical and optical characteristics and unlike the devices previously reported they do not require electrical burning to achieve high on/off current ratios.
Inbred‐Progeny Selection Is Predicted to Be Inferior to Half‐Sib Selection for Three Maize Populations (2009)

Historically, inbred progeny selection has been promoted as an effective means of improving both inbred and outbred performance, and in some cases as being superior to other methods. Advances in theory and new estimates of genotypic covariance components have allowed us to make better predictions of gain from inbred progeny selection than previously available. We developed predicted gain equations using a full model, based on new theory and estimates, and a reduced model, which contained only the additive genetic variance in the numerator, for three maize ( Zea mays L.) populations, BS13(S)C0, BSCB1(R)C13, and 3L Comp (HS‐S 1 ) S1 Outbred progeny selection was superior to inbred progeny selection for plant height and grain yield when the response unit was the outbred population. Inbred progeny selection was superior for plant height in both populations and more effective for grain yield in BS13(S)C0 in inbred response units. Negative estimates of the covariance parameter D 1 reduced predicted gain for inbred progeny selection in the full model in comparison to the reduced model when D 1 was ignored.
SPDF: Sparse Pre-training and Dense Fine-tuning for Large Language Models (2023)

The pre-training and fine-tuning paradigm has contributed to a number of breakthroughs in Natural Language Processing (NLP). Instead of directly training on a downstream task, language models are first pre-trained on large datasets with cross-domain knowledge (e.g., Pile, MassiveText, etc.) and then fine-tuned on task-specific data (e.g., natural language generation, text summarization, etc.). Scaling the model and dataset size has helped improve the performance of LLMs, but unfortunately, this also lead to highly prohibitive computational costs. Pre-training LLMs often require orders of magnitude more FLOPs than fine-tuning and the model capacity often remains the same between the two phases. To achieve training efficiency w.r.t training FLOPs, we propose to decouple the model capacity between the two phases and introduce Sparse Pre-training and Dense Fine-tuning (SPDF). In this work, we show the benefits of using unstructured weight sparsity to train only a subset of weights during pre-training (Sparse Pre-training) and then recover the representational capacity by allowing the zeroed weights to learn (Dense Fine-tuning). We demonstrate that we can induce up to 75% sparsity into a 1.3B parameter GPT-3 XL model resulting in a 2.5x reduction in pre-training FLOPs, without a significant loss in accuracy on the downstream tasks relative to the dense baseline. By rigorously evaluating multiple downstream tasks, we also establish a relationship between sparsity, task complexity and dataset size. Our work presents a promising direction to train large GPT models at a fraction of the training FLOPs using weight sparsity, while retaining the benefits of pre-trained textual representations for downstream tasks.

Challenges and approaches to on-chip millimeter wave antenna pattern measurements (2011)

We present two methods to remove wafer probe interference radiation from measured on-chip antenna patterns performed in a probe station environment. On-chip antenna pattern and gain measurements are affected by parasitic probe tip radiation as well as scattered energy from the metal probe station environment. In this work, we use superposition and S-parameter techniques to de-embed the effects of probe tip radiation. On-chip Dipole, Yagi, and Rhombic antennas were fabricated using standard 180nm CMOS, and radiation patterns were measured at 60 GHz. This work shows methods that improve the ability to reliably design, predict, and measure on-chip antenna patterns.

High Efficiency Silver-Free Heterojunction Silicon Solar Cell (2012)

In this work, we present the results of the replacement of silver screen printing on heterojunction crystalline silicon (c-Si) solar cells with a copper metallization scheme that has the potential to reduce the manufacturing cost while improving their performance. We report for the first time silver-free heterojunction c-Si solar cells on 6-in. wafers. The conversion efficiency reached is a record 22.1% for c-Si technology for this wafer size (Voc = 729 mV, Jsc = 38.3 mA/cm2, FF= 79.1%). The total power generated is more than 5 W for 1-sun illumination, which is a world record. Heat-damp reliability tests show comparable performance for mini-modules fabricated with copper metalized as for conventional silver screen printed heterojunction c-Si solar cells.
