Mode Selection and Power Allocation in Multi-Level Cache-Enabled Networks (2020)

Moving contents proximity to the network edge and proactively caching popular contents at multiple infrastructures are promising directions for solving the backhaul congestion problem. This letter proposes and evaluates a multi-level cache-enabled network, where cache-hit users can fetch their data from the available cache at either small base-stations, unmanned aerial vehicles, or cache-enabled mobile device-to-device users. Cache-miss users, on the other hand, fetch their data from the central cloud via limited capacity backhaul links. This letter considers the problem of maximizing the network weighted-sum rate by jointly determining the users' mode of operation and their transmit powers, subject to backhaul capacity and transmit power constraints. After showing how the association problem can be formulated as a generalized assignment problem, the letter solves the transmit power problem using an iterative function evaluation apprach. The resulting mode-selection and power-allocation (MSPA) iterative algorithm is then tested through numerical simulations, which suggest that, while being easily implementable, the proposed multi-level caching can substantially relieve the backhaul congestion, especially in dense-networks, and at low-backhaul capacity regimes.
In-situ nonlinear calibration of a RF signal chain (2018)

A new approach to linearize the cascade combination of multiple RF/mixed signal ICs, correcting in-situ for PCB imperfections and mutual loading is proposed. This allows to substantially reduce system design/prototyping cycles and to maximize the signal chain performance at a negligible power consumption cost. Experimental results performed with RF signals up to 3GHz and using a 12b/10GSPS ADC are reported, validating the effectiveness of the approach.
Experimental Demonstration of Multi-Channel Coherent Detection for Spectral Phase-Encoded OCDMA Systems (2006)

Liquid crystal polymer (LCP) for MEMS: processes and applications (2003)

In this paper we discuss newly developed microfabrication methods for liquid crystal polymer (LCP). LCP is a thermoplastic polymer made of aligned molecule chains with crystal-like spatial regularity. It exhibits unique electrical, physical and chemical properties, making it suitable for certain MEMS applications. MEMS-compatible fabrication processes such as metallization, plasma bulk etching and thermal bonding have been developed in our work. We demonstrated two micro sensor applications involving the LCP material.
Development of an education-oriented E-mail application "Seemit" and its utilization in a information literacy course (2004)

We have developed a simple E-mail application named Seemit which is designed for being used in information literacy courses. It has necessary and sufficient functions for an E-mail application, and it has been developed for the purpose of learning basic operations and mechanisms of E-mail transfer easily. It has been developed in HSP scripting language, which can create compact Windows native binaries. The E-mail application is indented to help users to avoid common mistakes in typing E-mail addresses and to understand the mechanisms of E-mail transfer over the net. It is a small set of binaries usable in removable media such as a floppy disk without installation procedures and has been released on the Web as a free software. It is equipped with the function to set automatically the configuration of user's SMTIVPOP3 servers and E-mail address, etc. The process of transferring E-mail via SMTP and POP3 can be demonstrated step by step showing actual messages passed from the client to a server and vice versa. We have utilized Seemit in a information literacy course which holds all the freshmen of our university, about 1800 students. Investigation for students and teachers' impressions of how useful and effective in learning E-mail basic functions and mechanisms show good results.
Deep-plant: Plant identification with convolutional neural networks (2015)

This paper studies convolutional neural networks (CNN) to learn unsupervised feature representations for 44 different plant species, collected at the Royal Botanic Gardens, Kew, England. To gain intuition on the chosen features from the CNN model (opposed to a ‘black box’ solution), a visualisation technique based on the deconvolutional networks (DN) is utilized. It is found that venations of different order have been chosen to uniquely represent each of the plant species. Experimental results using these CNN features with different classifiers show consistency and superiority compared to the state-of-the art solutions which rely on hand-crafted features.
B-trees, shadowing, and clones (2008)

B-trees are used by many file systems to represent files and directories. They provide guaranteed logarithmic time key-search, insert, and remove. File systems like WAFL and ZFS use shadowing, or copy-on-write, to implement snapshots, crash recovery, write-batching, and RAID. Serious difficulties arise when trying to use b-trees and shadowing in a single system. This article is about a set of b-tree algorithms that respects shadowing, achieves good concurrency, and implements cloning (writeable snapshots). Our cloning algorithm is efficient and allows the creation of a large number of clones. We believe that using our b-trees would allow shadowing file systems to better scale their on-disk data structures.
The role of cardiac registries in evidence-based medicine (2010)

Cardiovascular disease remains the primary cause of mortality, and a major cause of disability in the developed world.1 This significant burden necessitates ongoing improvements in patient management, to minimize the impact of cardiovascular conditions on both patients and healthcare systems. These improvements in cardiovascular care are promoted by an evidence-based approach, shaped by comprehensive clinical guidelines.

The scientific basis of recommendations is an important feature of clinical guidelines, and influences the degree to which they are followed in clinical practice.2 Recent studies have assigned the highest evidence grading to randomized controlled trials (RCTs) that are clinically important, and representative of the clinical population covered by the guideline recommendation.3 For example, this highest grading was assigned to a recommendation based on a meta-analysis of RCTs showing low-dose diuretics to be the most effective first-line treatment for cardiovascular event prevention in hypertensive patients. This study reviewed data from 42 RCTs which were, crucially, representative of the population that the recommendation was made for (i.e. hypertensive patients).3,4

The importance of the applicability of evidence to recommendations highlights the need to consider evidence from clinically relevant situations, not all of which have been assessed by RCTs. This evidence can originate from expert consensus, as well as non-randomized prospective studies. Although generally providing a lower evidence-level than RCTs,3,5 observational studies can make an important contribution to the evidence base when the study outcomes are clinically important, and the populations involved are representative. Indeed, information from several registries was considered in the recent American Heart Association Acute Coronary Care in the Elderly Scientific Statement.6

Non-randomized prospective registries document the treatment and outcomes for consecutive patients in clinical practice. Therefore, data are gained from a ‘real-world’ selection of patients, many of whom would be excluded from RCTs, …
Resonance vibrational Raman optical activity: A time-dependent density functional theory approach (2007)

We present a method to calculate both on- and off-resonance vibrational Raman optical activities (VROAs) of molecules using time-dependent density functional theory. This is an extension of a method to calculate the normal VROA by including a finite lifetime of the electronic excited states in all calculated properties. The method is based on a short-time approximation to Raman scattering and is, in the off-resonance case, identical to the standard theory of Placzek. The normal and resonance VROA spectra are calculated from geometric derivatives of the different generalized polarizabilites obtained using linear response theory which includes a damping term to account for the finite lifetime. Gauge-origin independent results for normal VROA have been ensured using either the modified-velocity gauge or gauge-included atomic orbitals. For the resonance VROA only the modified-velocity gauge has been implemented. We present some initial results for H(2)O(2) and (S)-methyloxirane and compare with predictions from a simple two-state approximation.
Disparate Mesenchyme-Lineage Tendencies in Mesenchymal Stem Cells from Human Bone Marrow and Umbilical Cord Blood (2005)

Bone marrow and umbilical cord blood are reported to be the main sources of mesenchymal stem cells (MSCs), which have been proposed for many clinical applications. This study evaluated and quantitated the differentiation potential of bone marrow-derived MSCs (bmMSCs) and cord blood-derived MSCs (cbMSCs) by in vitro induction. Results indicated that cbMSCs had a significantly stronger osteogenic potential but lower capacity for adipogenic differentiation than bmMSCs. Leptin, an important regulator of mesenchymal differentiation, has a significantly stronger effect of promoting osteogenesis and inhibiting adipogenesis in bmMSCs than in cbMSCs. Moreover, Cbfa1 mRNA expression in bmMSCs and cbMSCs was affected to different degrees by leptin during osteogenesis. In contrast, leptin reduced PPARgamma2 mRNA expression to the same level during adipogenesis in both types of MSCs. These results demonstrate the disparate capacities of MSCs from bone marrow and cord blood and suggest that they be used differently in experimental and therapeutic studies. In addition, the disparate differentiation tendencies of MSCs from different sources should be considered in further applications.
THE SYNTHESIS OF ACIDIC CHROMOSOMAL PROTEINS DURING THE CELL CYCLE OF HELA S-3 CELLS (1972)

The kinetics of acidic residual chromosomal protein synthesis and transport were studied throughout the cell cycle in HeLa S-3 cells synchronized by 2 mM thymidine block and selective detachment of mitotic cells. Pulse labeling the cells with leucine-(3)H for 2 min and then "chasing" the radioactive proteins for up to 3 hr showed that the amount of protein synthesized, transported, and retained in the acidic residual chromosomal protein fraction is greater immediately after mitosis and later in G(1) than in the S or G(2) phases of the cell cycle. During S, only 20-25% of the proteins synthesized and transported to the acidic residual chromosomal protein fraction are chased during the first 2 hr after pulse labeling, whereas up to 40% of the material entering the residual nuclear fraction in mitosis, G(1), and G(2) leaves during a 2 hr chase. Polyacrylamide gel electrophoretic profiles of these proteins, at various times after pulse labeling, reveal that the turnover of individual polypeptides within this fraction has kinetics of synthesis and turnover which are markedly different from one another and undergo stage-specific changes.
A new method for the analysis of signals: the Square-Wave method (2008)

The “Square-Wave Method” (SWM) presented here is a new method for the systematic analysis of signals – either locally or globally – depending on only one variable (time). The SWM is based on a technique (previously described elsewhere) for the representation of this type of signals using a sum of trains of square waves.&#x0D; The SWM is applied here to several analytically characterized signals and to an audio signal.

In addition to providing further pathophysiological support for the role of a nocturnal arginine vasopressin deficiency behind nocturnal polyuria in a subset of patients with enuresis, the results emphasize the clinical value of estimating nocturnal urine production on wet nights before selecting a therapeutic modality.

Circular heat map transition diagram (2013)

Eye tracking experiments are the state-of-the-art technique to study questions of usability of graphical interfaces. Visualizations help to analyse eye tracking data by presenting it in a graphical way. In this paper we contribute a new visualization technique combining features of state-of-the-art visualizations for eye tracking data like heat maps, and transition matrices with a circular layout. The circular heat map transition diagram uses areas of interest (AOIs) and orders them alphabetically on a circular layout to show transitions between AOIs visually. The AOIs are colour coded segments on a circle where the colour is mapped with respect to the fixation count in each AOI. The segment size corresponds to the fixation duration within an AOI. Furthermore, the transitions between and within the AOIs of a participant are drawn as arrow lines. Key features of the circular heat map transition diagram are extraction of similar eye movement patterns of different participants, graphical representation of transitions between AOIs, finding an appropriate AOI sequence, and investigating inefficient search behaviour of participants. To be able to use the visualization technique in practice, we have implemented three variants, the AOI transition diagram, the AOI transition and completion time diagram, and the fixation transition diagram. We will show their application in an exemplary analysis of an eye tracking experiment.
Laser chemical etching of copper films (1995)

Copper surface interactions with chlorine and carbon tetrachloride and a UV excimer laser are studied, in the context of applications to interconnects in microelectronic circuits. With Cl<SUB>2</SUB>, a highly reactive gas, the etching process is governed by bulk diffusion. With CCl<SUB>4</SUB>, which is less reactive, the limiting step is the creation of reactive species at the surface. The diffusion of active species in the gas phase is evidenced by a degree of nonuniformity of mm-sized etched spots.
Cross-layer architectural framework for highly-mobile multihop airborne telemetry networks (2008)

Highly dynamic mobile wireless networks present unique challenges to end-to-end communication, particularly caused by the time varying connectivity of high-velocity nodes combined with the unreliability of the wireless communication channel. Addressing these challenges requires the design of new protocols and mechanisms specific to this environment. Our research explores the tradeoffs in the location of functionality such as error control and location management for high-velocity multihop airborne sensor networks and presents cross-layer optimizations between the MAC, link, network, and transport layers to enable a domain specific network architecture, which provides high reliability for telemetry applications. We have designed new transport, network, and routing protocols for this environment: TCP-friendly AeroTP, IP-compatible AeroNP, and AeroRP, and show significant performance improvement over the traditional TCP/IP/MANET protocol stack.
Performance of STBC transmissions with real data (2007)

This paper presents a comparative study of three Space-Time Block Coding (STBC) techniques in realistic indoor scenarios. In particular, we focus on the Alamouti orthogonal scheme considering two types of Channel State Information (CSI) estimation: a conventional pilot-aided technique and a new blind method based on Second Order Statistics (SOS). We also considered a Differential (non-coherent) Space-Time Block code (DSTBC) that can be optimally decoded without CSI estimation, although it incurs in a 3 dB loss in performance. Experimental evaluation is carried out with a flexible and easy-to-use 2 x 2 MIMO platform at 2.4 GHz. Results show the excellent performance of the blind channel estimation technique in either Line-Of-Sight (LOS) and Non-LOS (NLOS) indoor scenarios.
Control of tumor growth by TSLP during colorectal cancer (2016)

Abstract Thymic stromal lymphopoietin (TSLP) is a cytokine involved in promoting tumor growth during breast and pancreatic cancer by promoting Th2 cell-mediated inflammation. Despite being essential to maintain Treg cell homeostasis in the mouse and human intestine, a role for TSLP in colorectal cancer has never been shown. To determine if TSLP affects tumor growth during colorectal cancer, we utilized a murine model of colitis-associated colorectal cancer. TSLP deficient mice exhibited decreased tumor numbers when compared to the WT littermate controls. Moreover, we found that tumors in TSLP−/− mice were also significantly smaller in size than WT mouse tumors. TSLP was mainly localized in the tumor tissue, indicating that it might be produced by cancer or cancer-associated cells. Further, TSLP receptor (TSLPR) expression was significantly upregulated after development of cancer. To determine if TSLP signals directly on the tumor cells, we utilized Villincre TSLPRflox mice in which the TSLPR expression is absent only in intestinal epithelial cells (IECs). Consistent with the TSLP−/− mice, lack of TSLP signaling on IECs led to a decrease in tumor number as well as tumor size, suggesting that TSLP signals directly on the IECs to promote tumor growth. Overall, these data show a novel role for TSLP in controlling tumor progression during colorectal cancer and identify it as a potential target for immunotherapy intervention.
Clock mutant mice with Jcl/ICR background shows an impaired learning ability in water maze, but not in passive avoidance, at the beginning of dark phase (2006)

We observed the learning ability in Clock mutant mice with Jcl/ICR background (Clockj), a mice model of evening-type individuals, in the early part of dark phase. In order to estimate the learning ability, Morris water maze (WM) and passive avoidance (PA) test were performed. Release of acetylcholine, 5 hydroxytryptophan (5-HT) and dopamine (DA) in hippocampus was measured by in vivo microdialysis method. Clockj showed the impaired learning ability in the WM, but not in PA test. Hippocampal acetylcholine release was significantly attenuated in the Clockj in comparison to the wild-type mice. Neither 5-HT nor DA in the hippocampus was affected by the Clock mutation. Clock, an essential gene controlling circadian rhythm, may have an important role on the spatial learning and hippocampal cholinergic function, at least, at the beginning of the dark phase.
Improving the learning experience for the deaf through augment reality innovations (2012)

One challenge facing the deaf is the need to divide their attention between subject matter and sign language interpreters. Sign language interpreters provide a visual interpretation of speech. However, the observation of an interpreter distracts an individual from other visual stimuli such as a presentation, demonstration or video. This paper proposes an augmented reality, head-mounted display system designed to improve the learning experience for the deaf, specifically a child's experience in a planetarium. The system uses augmented reality to enable a sign language interpreter to remain within the wearer's vision. This improves on subtitle-based alternatives by removing literacy as a requirement. The project is part of a three-year development calibration between three Brigham Young University departments and Gallaudet University, with funding from the National Science Foundation. This paper focuses on the design, prototyping and proposed usability testing performed by a team of six IT students for a senior capstone project.
Association of prediabetes by fasting glucose and/or haemoglobin A1c levels with subclinical atherosclerosis and impaired renal function: Observations from the Dallas Heart Study (2013)

Prediabetes defined by HbA1c and/or FPG criteria is crudely associated with markers of diabetic macro- and micro-vascular disease, but not after statistical adjustment, suggesting the relationships are attributable to other characteristics of the prediabetes population.
Preliminary Study on Callus Inducement to the seeds of New Variety Wheat E-en NO.4 (2005)

Selecting the matured embryo and half granule seed with embryo as explants of new variety wheat E-en NO.4, using MS as basic culture medium and mixing with six types content of 2,4-D and two types content of 6-BA to compose twelve composite culture mediums with different contents, the paper studies the effect of pretreatment seeds, hromone content and explant's effect on callus inducement. The results shows that MS+2,4-D at 2mg•L~(-1)--8 mg•L~(-1) can effectively induce callus formation, 2,4-D at 10mg•L~(-1) has certain retarding effect on callus formation; the recovery rate of half granule seeds with embryo are lower than those of matured embryo; the callus inductivity of seeds treated by normal temperature are higher than those processed by low temperature and CaCl_(2).
