Theoretical Study of Carrier Distribution and Small Signal Response in InGaAsP/InP Multiple Quantum Well Lasers (1993)

InGaAsP/InP multiple quantum well (MQW) lasers are one of the most important and promising active components for 1.3 or 1.55 μm optical communication systems. There have been a lot of work on the physical phenomena in the MQW lasers. In such an effort, especially in analyzing the small signal modulation dynamics as well as steady state characteristics in the MQW lasers, the carrier density or number in each well is usually assumed to be uniform among all the MQWs. However, it is not correct especially for the InGaAsP / InP MQWs, whose energy discontinuity of the valence band is larger than that of the conduction band, since the transport of holes is much slower. It is of great importance to know how uniformly carriers are distributed in order to investigate the high speed performance of the laser with many number of quantum wells. This theoretical work describes the distribution of both electrons and holes among the InGaAsP / InP MQW lasers by solving coupled rate equations with barrier states, three-dimensional like well states, and two-dimensional well states.

Analysis of Aggregated Interference at DTV Receivers in TV Bands (2008)

Several efforts are now underway to develop wireless technologies based on cognitive radios (CR) that can operate in the television (TV) band white space. One such example is the IEEE 802.22 Working Group (WG), which is formulating the first worldwide CR-based standard to operate in the TV bands. A mandatory requirement for any wireless technology operating in these bands is that it shall not cause harmful interfere with the passive TV receivers. In this paper we perform a comprehensive analysis of the effect of cumulative interference generated by the IEEE 802.22 system using circular cells and show how geometry plays an important role in the keep-out region. We then generalize our results and derive a generic formula to calculate the keep-out region for a typical deployment and for a variety of technologies.
Hierarchically Branched Siloxane Brushes for Efficient Harvesting of Atmospheric Water (2023)

Atmospheric water harvesting is considered a viable source of freshwater to alleviate water scarcity in an arid climate. Water condensation tends to be more efficient on superhydrophobic surfaces as the spontaneous coalescence-induced droplet jumping on superhydrophobic surfaces enables faster condensate removal. However, poor water nucleation on these surfaces leads to meager water harvest. A conventional approach to the problem is to fabricate micro- and nanoscale biphilic structures. Nonetheless, the process is complex, expensive, and difficult to scale. Here, the authors present an inexpensive and scalable method based on manipulating the water-repellent coatings of superhydrophobic surfaces. Flexible siloxane can facilitate water nucleation, while a branched structure promotes efficient droplet jumping. Moreover, ToF-SIMS analysis indicated that branched siloxane provides a better water-repellent coating coverage than linear siloxane and the siloxanes comprise hydrophilic and hydrophobic molecular segments. Thus, the as-prepared superhydrophobic surface, TiO<sub>2</sub> nanorods coated with branched siloxanes harvested eight times more water than a typical fluoroalkylsilane (FAS)-coated surface under a low 30% relative humidity and performed better than most reported biphasic materials.

Dual-Polarized Embroidered Textile Armband Antenna Array With Omnidirectional Radiation for On-/Off-Body Wearable Applications (2019)

In this article, a novel dual-polarized embroidered textile antenna array with an omnidirectional radiation pattern is proposed for both on- and off-body wearable applications. The flexible antenna is composed of a group of circularly oriented dual-polarized patch antennas excited with uniform amplitude and phase. The antenna array can be wrapped around a cylinder, such as an arm or a leg, for realizing a quasi-omnidirectional radiation pattern in the azimuthal plane, which is highly desirable in both on-body and off-body wearable applications. The operating principles and design consideration for how to achieve the omnidirectional radiation and how to avoid radiation nulls are investigated in detail. Moreover, these analytical studies are verified through the experimental results. In addition, a dual orthogonal polarization capability is employed to improve the link reliability. Due to the high front-to-back ratio (FBR) exhibited by each patch antenna element, the proposed omnidirectional antenna array also features a low specific absorption rate (SAR) and high efficiency, which are extremely important for wearable applications. As a proof-of-concept, an antenna array prototype operating at 5.8 GHz is designed, fabricated, and tested. The measured results agree reasonably well with the simulations in terms of S-parameters, polarization isolation, and radiation patterns, demonstrating that the proposed antenna array is ideally suited for potential wearable applications.

First Example of N-Heterocyclic Carbenes as Catalysts for Living Polymerization:  Organocatalytic Ring-Opening Polymerization of Cyclic Esters (2002)

A novel metal-free, organocatalytic approach to living polymerization is presented. N-heterocyclic carbenes were employed as nucleophilic catalysts for the ring-opening polymerization (ROP) of cyclic ester monomers. The catalysts is used in combination with an initiator, such as an alcohol, which generates an α-end group bearing the ester from the initiating alcohol upon ring-opening and a hydroxyl functional ω-chain end that propagates the chain. This class of catalyst proved to be more reactive than tertiary amine and phosphine nucleophiles, producing narrowly dispersed polymers of predictable molecular weights at room temperature in 1−2 h. Catalysis with respect to both initiating alcohol and monomer was observed. Control of the α and ω end-groups was demonstrated with a pyrene-labeled initiator, allowing the preparation of well-defined macromolecular architectures. Analogous to the ROP of cyclic esters using biocatalysts, the polymeriztion pathway using the N-heterocyclic carbenes is believed to ensue through a monomer-activated mechanism.
Biology of Cancer (2008)

“The science of today is the technology of tomorrow.” Edward Teller Interventional radiology (IR) techniques play an important role in cancer therapy by accessing and treating tumors via image-guided methods. These methods involve both local and regional therapies, with thermal ablative technology comprising the former and intra-arterial embolization with radioactive particles the latter. Combined with systemic chemotherapy, these techniques result in increased patient survival. A more recent approach for cancer therapy involves the use of drugs that specifically target molecular, biological or physiological processes. Examples of such targets include epithelial growth factor receptor (EGFR), vascular endothelial growth factor (VEGF), protein kinases, hypoxia inducible factor (HIF), cell cycle checkpoints, apoptosis, hypoxia and angiogenesis. Drugs specific to each of these targets are currently available or are in development; some of these agents may be applicable to interventional delivery. The purpose of this chapter is to review important aspects of tumor biology that may be targeted via an interventional approach. The clinical behavior of a tumor results from a complex set of interactions between neoplastic and non-neoplastic cells, blood vessels, blood and interstitial fluids using intercellular communication. These interactions define the tumor microenvironment, which continues to be extensively studied because there is evidence that it substantially influences tumor behavior and patient outcome (1, 2). This chapter begins with a review of the components and clinical/biological effects of hypoxia, pH, and glucose, discussed by Evans and Gatenby.
Mannose‐Functionalized Mesoporous Silica Nanoparticles for Efficient Two‐Photon Photodynamic Therapy of Solid Tumors (2011)

Influence of Fibers and Curing Conditions on the Pore Morphology in Plain and Fiber-Reinforced High-Performance Concrete through the Use of Computed Tomography Scan Technology (2020)

This paper analyzes the pore morphology of two different concrete mixtures (plain and fiber-reinforced) under two different curing conditions, through the use of a CT scanner and post-processing software. Twelve cylinders of 45.2 mm in diameter and 50 mm in height were cast. Half of the specimens were kept in a humidity-controlled room, at 20 °C and 60% humidity, and the rest in a curing room, at 20 °C and 100% humidity. All the specimens were scanned at the age of 28 days, using a micro CT scanner. The results reveal that the presence of fibers substantially modifies the pore morphology in the way of increasing the volume of voids and the pore-size, reducing the shape factor of the voids and reorienting the voids toward a direction more aligned to the one showed by the fibers. In general, the curing conditions do no exhibit a great impact on the results.

Towards Single Ultra-Low Dose CT Scan for Both Attenuation Map Creation and Localization in PET-CT Application (2005)

We have proposed the use of a single ultra-low dose CT scan for both attenuation map creation and localization purpose for PET applications. An adaptive filtering algorithm specifically for such imaging task has been developed to adequately reduce image noise and streaking artifacts and to provide clear delineation of major organs in low signal scanning conditions. Simulated ultra-low dose CT scans were used to evaluate the low-dose scan proposal and the associated adaptive filtering algorithm. The results demonstrated that with the use of a sophisticated pre-processing algorithm, we could utilize a single ultra-low dose CT scan to obtain accurate attenuation map and to provide excellent localization information for PET applications.
Panel-Sized TFT-LCD Column Driver (2006)

Panel-sized TFT-LCD column drivers have been fabricated on a glass substrate with TF CMOS and low-resistivity copper-plated interconnections. These operate with a 16.25MHz internal clock, have 6b DACs, 6b accuracy with either 3072 or 1536 outputs, and use an offset-controlled amplifier. The operation of 15 inch XGA LCDs is demonstrated using panel-sized column drivers.
Recapitulating the clinical scenario of BRCA‐associated pancreatic cancer in pre‐clinical models (2018)

Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal malignancies. BRCA-associated PDAC comprises a clinically relevant subtype. A portion of these patients are highly susceptible to DNA damaging therapeutics, however, responses are heterogeneous and clinical resistance evolves. We have developed unique patient-derived xenograft (PDX) models from metastatic lesions of germline BRCA-mutated patients obtained at distinct time points; before treatment and at progression. Thus, closely mimicking clinical scenarios, to further investigate treatment naïve and resistant patients. DNA was isolated from six BRCA-mutated PDXs and classified by whole-genome sequencing to stable-genome or homologous recombination deficient (HRD)-genome. The sensitivity to DNA-damaging agents was evaluated in vivo in three BRCA-associated PDAC PDXs models: (1) HRD-genome naïve to treatments; (2) stable-genome naïve to treatment; (3) HRD-genome resistant to treatment. Correlation between disease course at tissue acquisition and response to PARP inhibitor (PARPi)/platinum was demonstrated in PDXs in vivo. Only the HRD-genome PDX, naïve to treatment, was sensitive to PARP inhibitor/cisplatin treatments. Our results demonstrate heterogeneous responses to DNA damaging agents/PARPi in BRCA-associated PDX thus reflecting the wide clinical spectrum. An HRD-genome PDX generated from a naïve to treatment biopsy was sensitive to platinum/PARPi whereas no benefit was observed in treating a HRD-genome PDXs generated from a patient that had acquired resistance nor stable-genome PDXs.

Interpersonal entrainment of body sway in everyday face-to-face communication (2012)

This study investigates whether people entrain their body sway in everyday face-to-face communication. Interpersonal entrainment has been observed under experimental conditions, but not in daily life. We used wearable sensors to measure individual body vibration and face-to-face interactions in daily life. The observation included at least 100 participants from each of seen organization over a period of two to three months. We carried out measurements over a period of two to three months for each organization. It was found that the body vibration frequencies of two participants become more closer in face-to-face situations than in non-face-to-face situations. This result suggests that interpersonal entrainment of body sway occurs in everyday face-to-face communication.
Resource management in distributed SDN using reinforcement learning (2018)

Distributed software-defined networking (SDN), which consists of multiple inter-connected network domains and each managed by one SDN controller, is an emerging networking architecture that offers balanced centralized/distributed control. Under such networking paradigm, resource management among various domains (e.g., optimal resource allocation) can be extremely challenging. This is because many tasks posted to the network require resources (e.g., CPU, memory, bandwidth, etc.) from different domains, where cross-domain resources are correlated, e.g., their feasibility depends on the existence of a reliable communication channel connecting them. To address this issue, we employ the reinforcement learning framework, targeting to automate this resource management and allocation process by proactive learning and interactions. Specifically, we model this issue as an MDP (Markov Decision Process) problem with different types of reward functions, where our objective is to minimize the average task completion time. Regarding this problem, we investigate the scenario where the resource status among controllers is fully synchronized. Under such scenario, the SDN controller has complete knowledge of the resource status of all domains, i.e., resource changes upon any policies are directly observable by controllers, for which Q-learning-based strategy is proposed to approach the optimal solution.

Specific identification of tissue kallikrein in exocrine tissues and in cell-free translation products with monoclonal antibodies (1985)

A panel of six mouse monoclonal antibodies (IgG1) has been prepared against purified rat urinary kallikrein (EC 3.4.21.35) and characterized. In radioimmunoassay, the antibody titres of ascitic fluid giving 50% binding to 125I-kallikrein range from 1:2 X 10(3) to 1:1 X 10(6). Antibodies from four of the clones show no cross-reactivity with human urinary kallikrein, rat urinary esterase A or tonin. However, antibodies from a fifth clone cross-react with tonin and, from a sixth, with both urinary esterase A and tonin. Three of the kallikrein affinity-purified monoclonal antibodies inhibited, whereas one of the antibodies stimulated, kallikrein activity. Tissue kallikrein from rat submandibular-gland and pancreatic extracts and urine were labelled with [14C]di-isopropyl phosphofluoridate, immunoprecipitated with each of the six monoclonal antibodies and identified to be 38 kDa proteins, similar in size to purified rat urinary kallikrein. Western-blot analysis shows that 125I-labelled kallikrein monoclonal antibodies (V4D11) bind directly to a 38 kDa protein in submandibular-gland and pancreatic extracts and urine. Cell-free translation products of submandibular-gland polyadenylylated[poly(A)+]mRNA were immunoprecipitated with affinity-purified sheep anti-kallikrein antibodies and three monoclonal antibodies (V4D11, V4G6 and V1C3). Sodium dodecyl sulphate/polyacrylamide-gel electrophoresis of these immunoprecipitates revealed that two kallikrein precursors with Mr values of 37 000 and 35 000 are encoded by submandibular-gland mRNA. The third monoclonal antibody, V1C3, which binds to active kallikrein, did not recognize either precursor form. Collectively, the data show that these monoclonal antibodies comprise a set of powerful and specific reagents for studies of tissue kallikreins.
