Data from A Meta-analysis of Lung Cancer Gene Expression Identifies <i>PTK7</i> as a Survival Gene in Lung Adenocarcinoma (2023)

&lt;div&gt;Abstract&lt;p&gt;Lung cancer remains the most common cause of cancer-related death worldwide and it continues to lack effective treatment. The increasingly large and diverse public databases of lung cancer gene expression constitute a rich source of candidate oncogenic drivers and therapeutic targets. To define novel targets for lung adenocarcinoma, we conducted a large-scale meta-analysis of genes specifically overexpressed in adenocarcinoma. We identified an 11-gene signature that was overexpressed consistently in adenocarcinoma specimens relative to normal lung tissue. Six genes in this signature were specifically overexpressed in adenocarcinoma relative to other subtypes of non–small cell lung cancer (NSCLC). Among these genes was the little studied protein tyrosine kinase &lt;i&gt;PTK7&lt;/i&gt;. Immunohistochemical analysis confirmed that PTK7 is highly expressed in primary adenocarcinoma patient samples. RNA interference–mediated attenuation of PTK7 decreased cell viability and increased apoptosis in a subset of adenocarcinoma cell lines. Further, loss of PTK7 activated the MKK7–JNK stress response pathway and impaired tumor growth in xenotransplantation assays. Our work defines PTK7 as a highly and specifically expressed gene in adenocarcinoma and a potential therapeutic target in this subset of NSCLC. &lt;i&gt;Cancer Res; 74(10); 2892–902. ©2014 AACR&lt;/i&gt;.&lt;/p&gt;&lt;/div&gt;
First‐Principles Study of Twin Boundaries and Stacking Faults in β‐Ga2O3 (2023)

Abstract This study uses density functional theory calculations to explore the energetics and electronic structures of planar defects in monoclinic β ‐Ga 2 O 3 , including twin boundaries (TBs) and stacking faults (SFs). TBs on the (001)A, (001)B, (100)A, (100)B, and (−102) planes are examined; it is found that (100)A has a very low formation energy (0.01 Jm ‐ 2 ), consistent with its observation in a number of experiments. For SFs, SFs on the (100) plane have much lower energy (0.03 Jm ‐ 2 ) than SFs formed on the (010) and (001) planes. Growth on a (100) surface is thus expected to result in more planar‐defect formation, again consistent with experimental observations. In spite of their higher energies, TBs and SFs on planes other than (100) have been experimentally observed in epitaxial layers. Their origins are explained in terms of coalescence of different growth regions when the growth direction changes, or when low‐energy TBs on the growing surface lead to domains with different twinning orientation.
Whole-Genome Sequences of One Arthrobacter Strain and Three Pseudarthrobacter Strains Isolated from the Namib Desert (2019)

We report here the draft genome sequences of one <i>Arthrobacter</i> sp. strain (NamB2) and three <i>Pseudarthrobacter</i> sp. strains (NamE2, NamB4, and NamE5) isolated from topsoil in the Namib Desert, Namibia. The assemblies contain between 29 (NamB2) and 68 (NamE5) contigs >200 bp and range from 3.26 Mb (NamB2) to 4.03 Mb (NamE2). One plasmid was identified in <i>Pseudarthrobacter</i> sp. strain NamE5.

Determination of Zn-containing sites in β -Ga 2 O 3 film grown through mist chemical vapor deposition via X-ray absorption spectroscopy (2020)

Abstract The atomic structure of Zn for the Zn-doped β -Ga 2 O 3 film formed through mist chemical vapor deposition was investigated via X-ray absorption spectroscopy using a high-sensitivity detector and spectra simulations. The measured and simulated spectra agree, revealing that Zn atoms are located at substitutional Ga sites and at both tetrahedral and octahedral sites, not one of the two.
Solar PV array-inverter matching considering impact of environmental conditions (2011)

Sizing of photovoltaic (PV) generators is an important issue which might affect the PV system overall yield and performance ratio. The procedure is realized according to inverter specifications with the most important one being the operating voltage range. The parameter that is affected by this specification is the number of PV modules per string and a software tool was developed in order to study the effects of this parameter on the system performance. Moreover, the PV generator voltage is highly affected by the ambient temperature of a specific location. Thus, the optimum number of PV modules per string will differ in locations with different environmental conditions. The importance of PV string sizing is high, since improper string length can lead to significant deficiencies on the overall inverter performance. A study of the effects of PV string size on annual system energy production and yield has been conducted for several locations in Europe with significantly different weather as well as for locations with extreme climatic conditions such as high altitude and desert areas.
Pattern discovery from stock time series using self-organizing maps (2001)

† This work was supported by the RGC CERG project PolyU 5065/98E and the Departmental Grant H-ZJ84 ‡ Corresponding author ABSTRACT Pattern discovery from time series is of fundamental importance. Particularly when the domain expert derived patterns do not exist or are not complete, an algorithm to discover specific patterns or shapes automatically from the time series data is necessary. Such an algorithm is noteworthy in that it does not assume prior knowledge of the number of interesting structures, nor does it require an exhaustive explanation of the patterns being described. In this paper, a clustering approach is proposed for pattern discovery from time series. In view of its popularity and superior clustering performance, the self-organizing map (SOM) was adopted for pattern discovery in temporal data sequences. It is a special type of clustering algorithm that imposes a topological structure on the data. To prepare for the SOM algorithm, data sequences are segmented from the numerical time series using a continuous sliding window. Similar temporal patterns are then grouped together using SOM into clusters, which may subsequently be used to represent different structures of the data or temporal patterns. Attempts have been made to tackle the problem of representing patterns in a multi-resolution manner. With the increase in the number of data points in the patterns (the length of patterns), the time needed for the discovery process increases exponentially. To address this problem, we propose to compress the input patterns by a perceptually important point (PIP) identification algorithm. The idea is to replace the original data segment by its PIP’s so that the dimensionality of the input pattern can be reduced. Encouraging results are observed and reported for the application of the proposed methods to the time series collected from the Hong Kong stock market.
Atomic Layer Deposition of High-κ Dielectrics on Sulphur-Passivated Germanium (2011)

High mobility channels are currently being explored to replace the silicon channel in future CMOS technology nodes. However, until now the promising bulk properties are very difficult to translate into high transconductance due to a poor passivation of the interface between the gate dielectric and the channel. We have studied the S-passivation of the germanium surface combined with various high-permittivity dielectric gate stacks. (NH4)(2)S is used to achieve a S-terminated Ge surface. We found that the Ge/S/ Al2O3 interface is superior to both the Ge/S/ZrO2 and Ge/S/HfO2 interfaces. Bi-layer stacks consisting of Ge/S/Al2O3/HfO2 or Ge/ S/Al2O3/ZrO2 were built to achieve a gate stack with low EOT (Equivalent Oxide Thickness). In these bi-layer stacks, the Al2O3 thickness is reduced to a minimum without degradation of the interface properties. Rather thick Al2O3 interlayers (similar to 2 nm) are needed due to island growth on S-terminated Ge surface. A pMOSFET was built using a bi-layer gate stack (Ge/S/Al2O3/HfO2). The peak mobility of this device is &gt; 200 cm(2)/Vs at an EOT of 1.5 nm. (C) 2011 The Electrochemical Society. [DOI: 10.1149/1.3582524] All rights reserved.
Quantum transport in oxide nanostructures (2011)

We describe magnetotransport experiments performed on Hall crosses made from quantum wires at LaAlO3/SrTiO3 interfaces. Shubnikov-de Haas oscillations measured in a 14-nm wide structure exhibit modulations that are consistent with spin-orbit coupling or valley degeneracies. Hall measurements performed on the 6 nm-wide Hall cross reveal dissipative coupling to magnetic phases. Hall plateaus are observed that deviate significantly from two-dimensional quantum Hall counterparts. Non-monotonic dips in the Hall resistance are attributed to one-dimensional confinement and spin-orbit coupling.
Customized segment synthesis (1977)

Segment design is a process which must be exercised by every data-base designer. This paper presents an easily authomated method of designing segments taking into account system-usage factors. The segments resulting from this algorithm are a subset of all possible synthesis solutions; but they are those results which may be of more importance to the D.B. designer.

New current attenuator circuit in the current mode FFT LSI for OFDM (2003)

To achieve the high performance of current-mode fast-Fourier-transform (FFT) large-scaled integration (LSI) for orthogonal frequency division multiplexing (OFDM) system, a new current-attenuator circuit without a DC offset-current error is proposed. The attainable maximum scale accuracy to the input current is theoretically -80 dB in the proposed attenuator circuit. The circuit consists of N-current mirrors simply connected in parallel with one another. The output current of the circuit is reduced to 1/N of the input current. The proposed circuit exerts high accuracy on the current attenuation and enables us to design the current-mode 64-point FFT LSI for OFDM system.
Structural Assignment of Poecillastrins B and C, Macrolide Lactams from the Deep-Water Caribbean SpongePoecillastraSpecies (2006)

Two new chondropsin-type macrolide lactams, poecillastrins B (1) and C (2), were isolated from aqueous extracts of the marine sponge Poecillastra sp. These trace metabolites were isolated in low yield (400-600 microg), and their structures were determined primarily by analysis of NMR data acquired using a cyrogenically cooled probe. High-quality 1D and 2D NMR data sets allowed complete assignment of the spectroscopic data and defined the new structures as 35-membered ring analogues of poecillastrin A (3). Compounds 1 and 2 showed potent cytotoxic activity against a human melanoma tumor cell line (LOX) with an IC50 value of less than 1 microg/mL.
Flexible semiconductor devices: fingerprint sensor and electrophoretic display on plastic [TFT based] (2004)

We are on the brink of a new era in flexible semiconductor devices. Outstanding devices, such as a fingerprint sensor (FPS) and an active-matrix electrophoretic display (AM-EPD), are fabricated on a plastic sheet, using thin film transistor (TFT) technology. The devices are first fabricated on a glass substrate with high-performance low-temperature processed polycrystalline silicon (LTPS) TFTs, then later transferred onto a plastic sheet. The FPS and AM-EPD devices on plastic are presented in this paper as examples of flexible semiconductor devices.
Patient selection, education, and cannulation of percutaneous arteriovenous fistulae: An ASDIN White Paper (2019)

End-stage kidney disease patients who are candidates for surgical arteriovenous fistula creation commonly experience obstacles to a functional surgical arteriovenous fistula, including protracted wait time for creation, poor maturation, and surgical arteriovenous fistula dysfunction that can result in significant patient morbidity. The recent approval of two endovascular devices designed to create a percutaneous arteriovenous fistula enables arteriovenous fistula creation to be placed in the hands of interventionalists, thereby increasing the number of arteriovenous fistula providers, reducing wait times, and allowing the patient to avoid surgery. Moreover, current studies demonstrate that patients with percutaneous arteriovenous fistula experience improved time to arteriovenous fistula maturation. Yet, in order to realize the potential advantages of percutaneous arteriovenous fistula creation within our hemodialysis patient population, it is critical to select appropriate patients, ensure adequate patient and dialysis unit education, and provide sufficient instruction in percutaneous arteriovenous fistula cannulation and monitoring. In this White Paper by the American Society of Diagnostic and Interventional Nephrology, experts in interventional nephrology, surgery, and interventional radiology convened and provide recommendations on the aforementioned elements that are fundamental to a functional percutaneous arteriovenous fistula.
Calcium and Phosphorus Kinetics in Hemodialysis Therapy (2008)

The kinetics of interdialytic calcium (Ca) absorption and intradialytic flux are examined with particular emphasis on achievement of near zero Ca mass balance over complete dialysis cycles. It is concluded that a rational approach to management of mineral metabolism in hemodialysis consists of: (1) appropriate doses of vitamin D3 analogs to facilitate now normal Ca absorption and avoid both Ca overload and depletion; (2) adequate phosphorus (P) binder to normalize serum calcium and the Ca P product; (3) in most instances modest reduction of dialysate Ca to the level of 2.00-2.25 are appropriate to assure zero Ca balance, and (4) use of a calcimimetic to control secondary hyperparathyroidism.
Electron beam charging of a SiO2 layer on Si: a comparison between Monte Carlo-simulated and experimental results (2008)

Recently, a unique capability in highly sensitive detection of residue defects in photoresist patterns on a metal hard mask has been verified experimentally [T. Hayashi et al., Proc. SPIE, 6922 (2008) 6922-129]. In order to reveal the mechanism for the new defect inspection technique, the charging up induced by 300 eV - 2000 eV electron bombardment of thin insulating layers (SiO2, ~tens of nm) on Si is studied by using a self-consistent Monte-Carlo simulation of the transport of a primary electron and secondary electrons (SE) and the generation of an electric field due to the charges in the layer. The calculation is compared with the contrast changes in the SEM images of thermally oxidized layers (20~100 nm) on a Si wafer. Low-energy EB (or thick SiO2 layer) causes the positive charging of the layer, whereas the high-energy EB, which penetrates under thin SiO2 layer, relaxes the charging of the layer due to electron-hole recombination in Si. The thickness dependence of the SE yield for low- and high-energies is investigated, which explains the observed changes in the SEM images of the insulating layers on Si.
Study on hybrid method of ray-tracing and physical optics for outdoor-to-indoor propagation channel prediction (2014)

Recently, in order to evaluate the performance of heterogeneous networks, outdoor-to-indoor propagation characteristics have been actively investigated. In this paper, we evaluate the performance of a theoretical analysis method that is a hybrid of ray-tracing and physical optics with respect to the calculation accuracy. This is the first investigation to focus specifically on the calculation part of the physical optics. We show the impact on the accuracy and computational burden.
Estimation of Trap Density in AlGaN/GaN HEMTs from Subthreshold Slope Study (2007)

In this paper, we first demonstrate effects of thermal annealing on subthreshold slope in AlGaN/GaN HEMTs. Then, based on the temperature dependence of subthreshold slope, we introduce a new method to estimate interface trap density in these devices.The understanding of this interface trap is critical to optimize the gate modulation efficiency of these transistors and maximize their high frequency performance.
DSAC - Dynamic, Single Actuated Climber: Local stability and bifurcations (2010)

This paper investigates a novel mechanism, called DSAC for Dynamic, Single Actuated Climber, which propels itself upwards by oscillating its leg in a symmetric fashion using a single actuator. This mechanism achieves dynamic, vertical motion while retaining simplicity in design and control. We explore the local orbital stability of the DSAC mechanism. We use the Poincaré map method with a well chosen Poincaré section to simplify the problem by reducing the dimension of the Poincaré map to 3-dimensions. We find the stable regions while varying the controls input and some of the mechanism's parameters. Moreover, in response to a continuous change in a parameter of the mechanism, the symmetric and steady stable gait of the mechanism gradually evolves through a regime of period doubling bifurcations.
User-uncertainty : A human-centred uncertainty taxonomy for VGI through the visual analytics workflow (2018)

The emergence of Web 2.0 and ubiquitous mobile platforms makes it possible to collect a vast amount of information contributed by people (VGI). For example, crowdsourcing applications collect information from domains such as biodiversity, urban planning, and risk management, and other sources such as social media connect citizens that exchange voluntarily huge amount of posts on platforms like Twitter, Flickr, and Facebook. VGI differs from data coming from sensors, simulations, and mathematical models. It is highly dependent on the human wills to share the information, and the background and knowledge of the user, which introduces uncertainy. In this paper, we explore different dimensions of VGI uncertainty from the perspective of the human that contributes with the data, as well as the technology and systems used to collect the data. Our contributions include a new taxonomy that explicitly differentiates among the uncertainty introduced by the humans, we named User-Uncertainty and analyzed it at different steps of the Visual Analytics Workflow, and several use cases that illustrate our approach for the case of User-Uncertainty coming from the producers. We conclude our paper with a discussion about the potential uses and future work to be done to understand User-Uncertainty.
Thin PSG Process for 4H-SiC MOSFET (2014)

The use of phosphorous as a passivating agent for the SiO 2 /4H-SiC interface increases the field effect channel mobility of 4H-SiC MOSFET to twice the value, 30-40cm 2 /V-s, that is obtained with a high temperature anneal in nitric oxide (NO). A solid SiP 2 O 7 planar diffusion source is used to produce P 2 O 5 for the passivation of the interface. Incorporation of phosphorous into SiO 2 leads to formation of phosphosilicate glass (PSG) which is known to be a polar material causes device instability. With a new modified thin phosphorous (P) passivation process, as described in this abstract, we can improve the stability of MOSFETs significantly with mobility around 75cm 2 /V.s.
Practical and Theoretical Issues in Prefetching and Caching (CMU-CS-97-181) (2018)

This thesis has two parts, the first more practical, and the second more theoretical. The first part considers informed prefetching and caching in which an application provides information about its upcoming I/O accesses to the operating system, allowing the system to prefetch data and to make informed cache replacement decisions. I compare existing algorithms for this problem using trace-driven simulation, and use the results to develop a new algorithm that performs better than previous approaches, again under trace-driven simulation. The second part considers weighted caching, a theoretical problem from the domain of on-line algorithms. I present an algorithm with competitive ratio O(log2 k) on (k + 1)-point spaces, the first poly-logarithmic ratio for this problem. I also give an almost-tight lower bound of W(log k) for any weighted caching problem on at least k + 1 points. I then show a connection between this problem and a new on-line k-server model in which the servers may rearrange themselves without cost during "free-time" between requests, and describe a series of results in the free-time model.
