Application of the planar I/O terminal to dual mode dielectric waveguide filters (2002)

Planar I/O terminals have been applied to dual-mode dielectric waveguide filters. Two types of the filter, for Ku-band 13 GHz and K-band 22 GHz were designed and fabricated only by metal plating on the surfaces of a ceramic block. They are realized with very small volumes of less than 0.05 cc.
Application of SVD based spatial filtering to video sequences (2002)

Video capture devices, such as CCD cameras, are a significant source of noise in image sequences. Preprocessing of video sequences with spatial filtering techniques usually improves their compressibility. We present a block-based, non-linear filtering algorithm based on the theories of SVD and compression-based filtering. A novel noise estimation algorithm allows us to operate on the input data without any prior knowledge of either the noise or signal characteristics. Experiments with real video sequences and an MPEG codec have shown that SVD based filters preserve edge details and can significantly improve nearly-lossless compression ratios by 15%.
Understanding the impact of Tc and Hk variation on signal-to-noise ratio in heat-assisted magnetic recording (2014)

In this work, we present a micromagnetic study on the signal-to-noise ratio (SNR) impacts of Curie temperature, Tc, variation and anisotropy field, Hk, variation in FePt media for heat assisted magnetic recording. Results show that the SNR is much more sensitive to Tc variation than to Hk variation. The study shows the two causes yield different noise characteristics. The nature of the noise due to Tc variation is dominated by transition jitter whereas Hk variation increases erasure-after-write, resulting in both transition jitter and amplitude variation.
Design and Development of the Long-Jumping "Grillo" Mini Robot (2007)

This paper describes the design of a fast long-jumping robot conceived to move in unstructured environments through simple feed-forward control laws. Despite the apparent similarities with hopping, jumping dynamics is peculiar and involve non-trivial issues on actuation powering, energy saving and stability. The "Grillo" robot described here is a quadruped, 50-mm robot that weights about 15 grams and is suited for a long-jumping gait. Inspired by frog locomotion, a tiny motor load the springs connected to the hind limbs. At take-off, an escapement mechanism releases the loaded springs. This provides a peak power output that can exceed several times the maximum motor power. In this way, the actuation and energy systems can be significantly reduced in weight and size. On the other hand, passive dynamics is exploited by compliant forelegs, that let to partially recover the impact energy in their elastic recoil. Equipped with a 0.2W DC motor, the robot is dimensioned to achieve a forward speed of 1.5 m/s, which corresponds to about 30 body length per second.
Synthesis and Preliminary Biological Studies of Novel Retinamide Derivatives (2002)

We have described the synthesis and biological activity of novel retinamide . The retinamide derivatives were synthesized by introducing functional side chains into the 4-hydroxy group of 4-HPR. The activities could be dependent on the side chain length, functional group, and hetero atom. The antiprolife-rative potential of the derivatives was assessed by MTT assay in HCT116 cancer cell lines.
Adaptive hybrid clock discipline algorithm for the network time protocol (1998)

This paper describes the analysis, implementation, and performance of a new algorithm engineered to discipline a computer clock to a source of standard time, such as a GPS receiver or another computer synchronized to such a source. The algorithm is intended for the network time protocol (NTP), which is in widespread use to synchronize computer clocks in the global Internet, or with another functionally equivalent protocol such as DTSS or PCS. It controls the computer clock time and frequency using an adaptive-parameter hybrid phase/frequency lock feedback loop. Compared with the current NTP Version 3 algorithm, the new algorithm developed for NTP Version 4 provides improved accuracy and reduced network overhead, especially when per-packet or per-call charges are involved. The algorithm has been implemented in a special-purpose NTP simulator, which also includes the entire suite of NTP algorithms. The performance has been verified using this simulator and both synthetic data and real data from Internet time servers in Europe, Asia, and the Americas.
Response to Comment on “Modafinil Shifts Human Locus Coeruleus to Low-Tonic, High-Phasic Activity During Functional MRI” (2010)

Contrary to the arguments put forth by Astafiev et al ., our new analyses and high-resolution replication show that modulation of brain activity by the cognitive enhancing drug modafinil indeed localizes to the locus coeruleus. The authors’ critical stance regarding blood oxygen level–dependent imaging in the brainstem does not follow from their data.
Development of electromagnetic compatibility courses at the City University of Hong Kong (2012)

EMC compliance is a mandatory requirement for electronic and electrical devices export to European countries and the USA. Hong Kong is an export-oriented city with 23% of the total export in electronic and electrical products; knowledge in EMC design and standards are highly desirable to engineers in Hong Kong. To cater for these particular needs of the local industry, EMC was introduced as an undergraduate course in 1994, prior to the effective date of implementation of EMC Directive 89/336/EEC in 1996. After 15-years of development and modification, the EMC course has now become one of the most popular postgraduate courses in Hong Kong. The course includes lectures, EMC standard interpretation, case studies, together with an emphasis on the hands-on experience of EMC tests and facilities in the EMC test laboratory. In this paper, a summary of the development of the EMC course at the City University of Hong Kong in the last decade are presented, and some possible future EMC needs are discussed at the end.
Live Forensic Analysis of a Compromised Linux System Using LECT (Linux Evidence Collection Tool) (2008)

The Linux operating system has been used as a server system in plenty of business services worldwide. Nowadays, a lot of incident response approaches on such kind of platform have been established by many researchers active in the computer forensic discipline. Interestingly, many frameworks about how to deal with a live digital investigation on a Linux systems have been illustrated in the forensic literature. Conversely, as a matter of fact, there are not so many tools for approaching live forensic of a Linux system. Thus, we have developed and implemented a new framework to deal with a compromised Linux system in a digital forensic investigation. The resulting framework has been called LECT (Linux Evidence Collection Tool) ant aims to represent a significant contribution in the field of live forensic analysis of Linux based systems.
Fluidic self-assembly of silicon microstructures (2002)

Fluidic self-assembly is a new technique which makes possible the integration of devices fabricated using dissimilar materials and processes. The integration is accomplished by fluidically transporting trapezoidally shaped blocks made of one material into similarly shaped holes in a receptor substrate. In this paper, a systematic study of the FSA integration efficiency is presented. Blocks and holes were formed from silicon using anisotropic etching. Two different sizes were considered: large blocks of dimension 1.0 mm/spl times/1.2 mm, and small blocks of dimension 150 /spl mu/m/spl times/150 /spl mu/m. FSA was performed in either water or methanol using a bubble pump apparatus to recirculate blocks. FSA of large blocks resulted in 100% filling of a substrate containing 191 holes within 2.5 minutes. Similar experiments with small blocks and a substrate with a 64/spl times/64 array of holes yielded a fill ratio of 70%, due to undesirable adhesion of blocks to the substrate surface. Roughening the substrate resulted in a fill ratio of 90%. Also presented is a simple rate equation model of the FSA process, along with a discussion of which process parameters are important and how they can be optimized.
In Silico hERG Modeling: Challenges and Progress (2009)

The first generation of in silico hERG models have focused on key driving forces for hERG/ligand binding: basicity and lipophilicity. While reducing basicity and lipophilicity are typically the first line approaches to eliminating hERG blocking activity, in many programs these are not feasible approaches because basicity and lipophilicity are frequently necessary for achieving good pharmacokinetics or primary target binding. Thus for the second, generation of in silico hERG models, a focus on understanding the more subtle aspects of hERG binding is necessary. Thus, the focus of this review is on extracting ideas, either qualitative or quantitative, from the various modeling efforts as to how hERG activity might be eliminated or diminished beyond simply reducing basicity and lipophilicity. In addition, several areas where key questions around hERG binding have not been adequately addressed by in silico work are highlighted.
The paperless factory (2003)

Eliminating the paperwork not only saves trees, but also saves money. The accuracy of the shop floor data will increase, allowing you to make better business decisions. Quality will go up because the correct documentation will always be where it needs to be and extensive data analysis can be easily done to look for defect trends and trouble spots. Productivity will increase because the tools to perform an operation are delivered right to the operator. Whether it is assembly prints, test procedures, data sheets, or material flow, information is power.

De la mesure de laboratoire à la mesure en ligne et en continu des propriétés radiatives des tôles (1998)

Compte tenu de l’évolution des procédés de fabrication des différents produits sidérurgiques, les besoins de caractérisation de leurs propriétés radiatives n’ont cessé d’augmenter. Les propriétés radiatives des produits industriels sont des paramètres physiques qu’il est indispensable de bien connaître, que ce soit pour la mesure de température par pyrométrie optique ou pour la modélisation des transferts thermiques. Des efforts et moyens importants ont été consentis afin de disposer d’outils de caractérisation précis : un dispositif de mesure d’émissivité par émission infrarouge et une sphère intégrante qui permet de déterminer l’émissivité par réflexion infrarouge. Pour pouvoir suivre l’évolution des bandes sur les lignes industrielles, nous avons imaginé un prototype de mesure en ligne et en continu des propriétés radiatives basé sur le même principe physique que la mesure par réflexion infrarouge. Cette mesure permet ainsi de suivre l’absorptivité totale des bandes avant leur traitement thermique.
Example-Driven Manifold Priors for Image Deconvolution (2011)

Image restoration methods that exploit prior information about images to be estimated have been extensively studied, typically using the Bayesian framework. In this paper, we consider the role of prior knowledge of the object class in the form of a patch manifold to address the deconvolution problem. Specifically, we incorporate unlabeled image data of the object class, say natural images, in the form of a patch-manifold prior for the object class. The manifold prior is implicitly estimated from the given unlabeled data. We show how the patch-manifold prior effectively exploits the available sample class data for regularizing the deblurring problem. Furthermore, we derive a generalized cross-validation (GCV) function to automatically determine the regularization parameter at each iteration without explicitly knowing the noise variance. Extensive experiments show that this method performs better than many competitive image deconvolution methods.

CyclopsDistMedDB - a transparent gateway for distributed medical data access in DICOM format (2003)

The image diagnosis area is the biggest medical field in telemedicine, because it does not obligate a direct contact of the patient with the responsible radiologist during the building of the report. The persistent lack of specialists in places distant from urban centers makes telemedicine an important tool for the improvement of healthcare services. In this paper, we present a framework, called CyclopsDistMedDB (Cyclops Distributed Medical Database), for the integration of distributed DICOM medical record databases over wide areas. The system has a central module that is responsible for receiving the clients' requests about patient data (images, waveforms), performing the querying and retrieval of images, patient records, etc. from the specific DICOM databases containing the data requested, and delivering them to the clients. The data communication protocols adopted are DICOM, for retrieval of objects directly from the DICOM data servers, and CORBA (Common Object Request Broker Architecture), for the delivery of DICOM data to client applications.
Silicon Mach-Zehnder modulator of extinction ratio beyond 10 dB at 100-125 Gbps (2011)

Silicon Mach-Zehnder modulators with reduced series resistance in lateral PN junction rib-waveguide phase shifters for enhanced high-speed response are fabricated and characterized. Extinction ratio higher than 10 dB is obtained at 10.3-11.7 Gbps with mask margins of 27% (10.3-Gbps 10GBE), 16% (10.7-Gbps STM-64/OC-192) and 10% (11.3-Gbps STM-64/OC-192) in eye-diagram measurements incorporating mask tests using a RF cut-off filter. In unfiltered eye-diagram measurements without mask tests, extinction ratio higher than 13 dB is obtained at 10.0-12.5 Gbps. The silicon modulators reveal high-speed performance comparable with that of lithium-niobate modulators in high-speed optical fiber telecommunications.
A Deep-Learning-Based Multi-modal ECG and PCG Processing Framework for Cardiac Analysis (2022)

<sub>The need for telehealth and home-based monitoring surges during the COVID-19 pandemic. Based on the recent advancement of concurrent electrocardiograph (ECG) and phonocardiogram (PCG) wearable sensors, this paper proposes a novel framework for synchronized ECG and PCG signal analysis for cardiac function monitoring. Our system jointly performs R-peak detection on ECG, fundamental heart sounds segmentation of PCG, and cardiac condition classification. First, we propose the use of recurrent neural networks and developed a new type of labeling method for R-peak detection algorithm. The new labeling strategy utilizes a regression objective to resolve the previous imbalanced classification problem. Second, we propose a 1D U-Net structure for PCG segmentation within a single heartbeat length. We further utilize the multi-modality of signals and contrastive learning to enhance model performance. Finally, we extract 20 features from our signal labeling algorithms to apply to two real-world problems: snore detection during sleep and COVID-19 detection. The proposed method achieves state-of-the-art performance on multiple benchmarks using two public datasets: MIT-BIH and PhysioNet 2016. The proposed method provides a cost-effective alternative to labor-intensive manual segmentation, with more accurate segmentation than existing methods. On the dataset collected by Bayland Scientific which includes synchronized ECG and PCG signals, the proposed system achieves an end-to-end R-peak detection with F1 score of 99.84%, heart sound segmentation with F1 score of 91.25%, and snore and COVID-19 detection with accuracy of 96.30% and 95.06% respectively. </sub>
HIV‐1 Coreceptor Use in Triple‐Class Treatment–Experienced Patients: Baseline Prevalence, Correlates, and Relationship to Enfuvirtide Response (2006)

At baseline, D/M strains were associated with lower CD4(+) cell counts but similar viral loads, compared with R5 strains, and were common across CD4(+) cell count strata. The comparable virological and immunological responses and bias toward shifts from D/M to R5 strains in patients who received enfuvirtide support its use in triple-class treatment-experienced patients and its study as a therapeutic partner for coreceptor-binding inhibitors.
A Phase II Clinical and Pharmacodynamic Study of E7070 in Patients with Metastatic, Recurrent, or Refractory Squamous Cell Carcinoma of the Head and Neck (2004)

At this dose and schedule, E7070 is unlikely to be superior over single-agent chemotherapy in SCCHN. However, the data suggest that cdk activity can be inhibited in tumor cells, resulting in posttreatment modulation of Rb phosphorylation. In the absence of cytotoxicity, more frequent administration of E7070 may be required to sustain Rb hypophosphorylation and cytostatic growth arrest.

Selective laser suture lysis with a compact, low-cost, red diode laser (2008)

The argon (blue-green) laser is currently used for vaporization of sutures during ophthalmic surgery. However, previous studies have reported more effective laser suture lysis and a lower rate of complications using the krypton (red) laser. Red wavelengths are selectively absorbed by the nylon sutures, but are minimally absorbed by adjacent tissue, and not absorbed by hemoglobin, unlike the argon laser wavelengths. More compact and less expensive red diode lasers have recently become commercially available for surgical applications. This study explores the use of a compact, lowpower, red diode laser for selective laser suture lysis. A 225 mW, 660-nm diode laser was used to vaporize 10-0 nylon sutures in human cornea samples with a single laser pulse, pulse energy of 150 mJ, pulse duration of 100 ms, and spot diameter of 55 mum. The red diode laser may represent an inexpensive, compact, and safer alternative laser for use in laser suture lysis during ophthalmic surgery.
