A Web-based Information System for Plant Disease Forecast Based on Weather Data at High Spatial Resolution (2010)

This paper describes a web-based information system for plant disease forecast that was developed for crop growers in Gyeonggi-do, Korea. The system generates hourly or daily warnings at the spatial resolution of <TEX>$240\;m{\times}240\;m$</TEX> based on weather data. The system consists of four components including weather data acquisition system, job process system, data storage system, and web service system. The spatial resolution of disease forecast is high enough to estimate daily or hourly infection risks of individual farms, so that farmers can use the forecast information practically in determining if and when fungicides are to be sprayed to control diseases. Currently, forecasting models for blast, sheath blight, and grain rot of rice, and scab and rust of pear are available for the system. As for the spatial interpolation of weather data, the interpolated temperature and relative humidity showed high accuracy as compared with the observed data at the same locations. However, the spatial interpolation of rainfall and leaf wetness events needs to be improved. For rice blast forecasting, 44.5% of infection warnings based on the observed weather data were correctly estimated when the disease forecast was made based on the interpolated weather data. The low accuracy in disease forecast based on the interpolated weather data was mainly due to the failure in estimating leaf wetness events.
A LCG-based Secure Protocol for Wireless Sensor Networks (2006)

In this paper, based on a Linear Congruential Generator (LCG), we propose a new block cipher that is suitable for constructing a lightweight secure protocol for resource-constrained wireless sensor networks. Based on the Plumstead's inference algorithm, we are motivated to embed the generated pseudo-random numbers with sensor data messages in order to provide security. Specifically, the security of our proposed cipher is achieved by adding random noise and random permutations to the original data messages. The analysis of our cipher indicates that it can satisfy the security requirements of wireless sensor networks. We demonstrate that secure protocols based on our proposed cipher satisfy the baseline security requirements: data confidentiality, authenticity, and integrity with low overhead. Performance analysis demonstrates that our proposed block cipher is more lightweight than RC5 in terms of the number of basic operations.
UCP1 in Brite/Beige Adipose Tissue Mitochondria Is Functionally Thermogenic (2013)

The phenomenon of white fat "browning," in which certain white adipose tissue depots significantly increase gene expression for the uncoupling protein UCP1 and thus supposedly acquire thermogenic, fat-burning properties, has attracted considerable attention. Because the mRNA increases are from very low initial levels, the metabolic relevance of the change is unclear: is the UCP1 protein thermogenically competent in these brite/beige-fat mitochondria? We found that, in mitochondria isolated from the inguinal "white" adipose depot of cold-acclimated mice, UCP1 protein levels almost reached those in brown-fat mitochondria. The UCP1 was thermogenically functional, in that these mitochondria exhibited UCP1-dependent thermogenesis with lipid or carbohydrate substrates with canonical guanosine diphosphate (GDP) sensitivity and loss of thermogenesis in UCP1 knockout (KO) mice. Obesogenic mouse strains had a lower thermogenic potential than obesity-resistant strains. The thermogenic density (UCP1-dependent oxygen consumption per g tissue) of inguinal white adipose tissue was maximally one-fifth of interscapular brown adipose tissue, and the total quantitative contribution of all inguinal mitochondria was maximally one-third of all interscapular brown-fat mitochondria, indicating that the classical brown adipose tissue depots would still predominate in thermogenesis.
Zeolitic imidazolate framework-8 as efficient pH-sensitive drug delivery vehicle (2012)

Zeolitic Imidazolate Framework-8 (ZIF-8), for the first time for ZIFs, exhibits a remarkable capacity for the anticancer drug 5-fluorouracil (5-FU), around 660 mg of 5-FU/g of ZIF-8, and presents a pH-triggered controlled drug release property. These prove ZIF-8 to be a valuable candidate for delivery of anticancer agents and reveal its potential applications in the treatment of cancer.
1 € filter (2012)

The 1 € filter ("one Euro filter") is a simple algorithm to filter noisy signals for high precision and responsiveness. It uses a first order low-pass filter with an adaptive cutoff frequency: at low speeds, a low cutoff stabilizes the signal by reducing jitter, but as speed increases, the cutoff is increased to reduce lag. The algorithm is easy to implement, uses very few resources, and with two easily understood parameters, it is easy to tune. In a comparison with other filters, the 1 € filter has less lag using a reference amount of jitter reduction.
Clinical use of sodium nitroprusside in chronic ischemic heart disease. Effects on peripheral vascular resistance and venous tone and on ventricular volume, pump and mechanical performance. (1975)

Although hemodynamic benefit has been shown with sodium nitroprusside (NP) in acute coronary pump failure, complete understanding of the mechanisms of action of the agent on the cardiocirculation and its value in chronic ventricular dysfunction are lacking. This investigation evaluates the effects of NP on the systemic and regional arterial and venous beds and on cardiac dynamics, ventricular volumes, contractile state and myocardial energetics in long-standing congestive heart failure. Twelve patients with chronic coronary pump dysfunction received NP infusion to lower systolic pressure to 95-105 mm Hg. Left ventricular (LV) function was assessed directly by angiographic volumes and high fidelity pressure, and peripheral circulatory dynamics were determined simultaneously by forearm arterial and venous plethysmography. NP reduced mean arterial pressure (MAP) from 88.2 to 73.4 mm Hg (P less than 0.05) and significantly (P less than 0.05) enhanced the variables of LV performance: LV end-diastolic pressure (EDP) diminished from 18.5 to 9.9 mm Hg; ejection fraction rose from 0.47 to 0.55; percent of LV segmental shortening increased; and isovolumic and ejection indices of contractility improved. Concomitantly, NP reduced the indices of myocardial oxygen demands of ventricular tension time index and LVED volume index. These salutary effects on LV performance and energetics occurred secondary to peripheral arterial and venous dilation (P less than 0.05) produced by NP: total systemic vascular resistance was lowered from 1590 to 1310 dynes sec cm--5; forearm vascular resistance diminished from 46 to 37 mm Hg/ml/100 gm/min; and forearm venous tone fell from 14.2 to 10.1 mm Hg/cc. Depressed stroke index (SI) and cardiac index (CI) increased (P less than 0.05) with NP: despite the fall in LVEDP, when ventricular filling pressures with the agent were at levels slightly above normal. Dextran infusion given with NP to restore LVEDP to moderately elevated values increased SI and CI (P less than 0.05) when NP alone produced no change in stroke output. Thus, the peripheral vasodilator properties of nitroprusside improve LV function by reducing impedance to ventricular ejection, while MVO2 is diminished by decreasing LV preload and afterload through relaxing actions
Representing and applying teaching strategies in computer-based learning-by-doing tutors (1996)

A problem with the current paradigm of developing educational software is that each application is developed independently and teaching decisions are often ad-hoc and hard-coded into individual applications. There is very little reuse of teaching code or teaching knowledge between applications because we lack (a) a standard language for representing the knowledge, (b) a standard interface to allow applications to access the knowledge, and (c) a set of tools to allow designers to manipulate the knowledge.
This dissertation describes solutions to all three of these problems as they are embodied in the Teaching Executive. The Teaching Executive is a software tool that serves as a repository of teaching strategies and provides a means for incorporating these teaching strategies into new educational applications. With the Teaching Executive, teaching strategies used in earlier applications can be reused when building new applications that require similar teaching interventions.
In addition, an analysis of the kinds of teaching needed in two different types of computer-based learning-by-doing tutors is presented. Fourteen teaching strategies useful for teaching procedural tasks, and seventeen teaching strategies useful for teaching diagnosis tasks are described in detail, along with examples of their use in actual applications.
Silver and Gold Glyconanoparticles for Colorimetric Bioassays (2006)

The color changes associated with the aggregation of metal nanoparticles has led to the development of colorimetric-based assays for a variety of target species. We have examined both silver- and gold-based nanoparticles in order to establish whether either metal exhibits optimal characteristics for bioassay development. These silver and gold nanoparticles have been stabilized with a self-assembled monolayer of a mannose derivative (2-mercaptoethyl alpha-d-mannopyranoside) with the aim of inducing aggregation by exploiting the well-known interaction between mannose and the lectin Concanavalin A (Con A). Both metal glyconanoparticles were determined to be ca. 16 nm in diameter (using TEM measurements). Aggregation was observed on addition of Con A to both silver and gold nanoparticles resulting in a shift in the surface plasmon absorption band and a consequent color change of the solution, which was monitored using UV-visible spectrophotometry. Mannose-stabilized silver nanoparticles at a concentration of 3 nM provide an assay for Con A with the largest linear range (between 0.08 and 0.26 microM). Additionally, the kinetic rate of aggregation of the silver-nanoparticle-based bioassay was significantly greater than that of the gold-nanoparticle system. However, in terms of sensitivity, the mannose-stabilized gold-nanoparticle-based assay was optimum with a limit of detection of 0.04 microM Con A, as compared with a value of 0.1 microM obtained for the mannose-stabilized silver nanoparticles. Additionally, a lactose derivative (11-mercapto-3,6,9-trioxaundecyl beta-D-lactoside) was used to stabilize gold nanoparticles to induce aggregation upon addition of the galactose specific lectin Ricinus communis agglutinin (RCA(120)). To examine the specificity of the bioassay, lactose-stabilized gold nanoparticles were mixed with a solution of mannose-stabilized silver nanoparticles to give an aggregation assay capable of detecting two different lectins. When either Con A or RCA(120) was added to the mixed glyconanoparticles, selective recognition of the respective natural ligand was shown by aggregation of a single metal nanoparticle. Centrifugation and removal of the aggregated species enabled further bioassay measurements using the second glyconanoparticle system.
Performance Analysis of AES candidates on the 6805 CPU core (1999)

The AES candidate block ciphers Crypton, Mars, RC6, Rijndael, and Serpent were implemented on the Motorola 6805 series 8-bit architecture. Their performance, including ROM and RAM sizes and time to encrypt a single block, was measured in simulation, and the results presented and compared with results for the other NIST cryptography algorithms SHA and DEA and previously published results for AES candidate Twofish. Rijndael was found to be the clear “winner”, but the ciphers Crypton, Serpent, and Twofish also performed acceptably. The NIST is currently evaluating block cipher algorithms as part of its Advanced Encryption Standard development effort. Among the requirements for the AES is that it should be efficient on small 8-bit processors as found in smart cards. Unfortunately, although most of the AES submissions presented performance estimates (sometimes even timings of actual implementations) for some kind of 8-bit processor, there were almost as many 8-bit processors used as there were submissions. In this paper, we hope to rectify this by implementing the most likely AES candidates for a single 8-bit platform, the Motorola 6805 series [3] and measuring their performance in simulation. The candidates chosen were Crypton, Mars, RC6, Rijndael, and Serpent. The authors of the Twofish AES submission [8] have already implemented Twofish on a 6805 CPU, so we simply quote their results below. These include the fastest five algorithms on the reference platform. There is some discussion below of the next two fastest candidates, CAST and E2. 1 The 6805 processors The processor family we chose is based around the Motorola HC05 core. There are a large number of variants, all of which use the same instruction set and tim-
Medications for Alcohol Use Disorder. (2016)

The U.S. Preventive Services Task Force recommends that clinicians screen adults for alcohol misuse and provide persons engaged in risky or hazardous drinking behaviors with brief behavioral counseling to reduce alcohol misuse. However, only a minority of American adults with high-risk alcohol use receive treatment. Three medications are approved by the U.S. Food and Drug Administration to treat alcohol use disorder: acamprosate, disulfiram, and naltrexone. Acamprosate and naltrexone reduce alcohol consumption and increase abstinence rates, although the effects appear to be modest. Disulfiram has been used for years, but evidence supporting its effectiveness is inconsistent. Other medications may be beneficial to reduce heavy alcohol use. The anticonvulsants topiramate and gabapentin may reduce alcohol ingestion, although long-term studies are lacking. Antidepressants do not decrease alcohol use in patients without mood disorders, but sertraline and fluoxetine may help depressed patients decrease alcohol ingestion. Ondansetron may reduce alcohol use, particularly in selected subpopulations. Further study is needed for genetically targeted or as-needed medications to reduce alcohol use.
Stilbazolium based zwitterionic chromophores for electro-optic polymers (1997)

Abstract A series of stilbazolium based zwitterionic chromophores was synthesized. They have very large dipole moment (up to μ = 13x10-29 Cm) and high molecular hyperpolarizability (up to β = 135x10-40 m4V-1). Guest-host polymer thin films of the best molecules were prepared and poled by corona discharge. Values of the nonlinear optical coefficient (d31 = 0.7 pm/V. at γ = 1.545 nm) at molecular concentrations of 5x1019 m-3, comparable to that of Disperse Red 1, were obtained. The good molecular characteristics and macroscopic performance of these chromophores combined with their good thermal stability make them promising candidates for side-chain electro-optic polymers.

Cloud-based Data Center Design as a Data Storage Infrastructure on Internet of Things (2019)

The widespread use of Internet of Things (IoT) has effect in a growing number of hardware devices that can be controlled and monitored using a variety of applications. It affects the amount of data that must be collected to be analyzed and processed according to user requirement. The greater the data collected results in requirement of storage media that has access management and scalability that are effective and efficient. The data collected in cloud-based infrastructure namely Openstack. Implementation in this research by involving two physical device of server as main infrastructure that located in network of Faculty of Computer Science, Brawijaya University Malang which used as controller node and compute node. Controller can adapt to the use of various dashboard and provide a good access management service for users to request and create instances in Openstack. The resulting data center shows good performance based on scalability, access, and performance of data transmission from IoT sensors. The test is done gradually by adding requirement of compute nodes up to 24 VCPU, 48 GB of RAM, and 235 GB of HD storage in registered instances. Access at the data center can be done either from faculty internal network (private) and faculty external network (public) with access time under 100 ms.
Heat Transfer and Friction Factor Measurements in Ducts With Staggered and In-Line Ribs (1993)

The combined effects of rib alignment and channel aspect ratio on the distributions of the local heat transfer coefficient and on the friction factors for developing and fully developed flow in short square and rectangular channels (L/DH = 13.5–18) with a pair of opposite rib-roughened walls were determined for Reynolds numbers ranging from 13,000 to 130,000. The channel aspect ratios are 1/2 and 1 and the rib alignment configurations are arranged as staggered and in-line types, respectively. The pitch to rib height ratio is 5.31 for all test channels. The local heat transfer distributions on the bottom rib-roughened wall from the channel entrance to the downstream region are presented and discussed. Semi-empirical heat transfer and friction correlations are developed, and the results are compared with those of previous investigations for similarly configured channels, which were roughened by regularly spaced transverse ribs.

Uniform Central Limit Theorems (1999)

This book shows how the central limit theorem for independent, identically distributed random variables with values in general, multidimensional spaces, holds uniformly over some large classes of functions. The author, an acknowledged expert, gives a thorough treatment of the subject, including several topics not found in any previous book, such as the Fernique-Talagrand majorizing measure theorem for Gaussian processes, an extended treatment of Vapnik-Chervonenkis combinatorics, the Ossiander L2 bracketing central limit theorem, the Giné-Zinn bootstrap central limit theorem in probability, the Bronstein theorem on approximation of convex sets, and the Shor theorem on rates of convergence over lower layers. Other results of Talagrand and others are surveyed without proofs in separate sections. Problems are included at the end of each chapter so the book can be used as an advanced text. The book will interest mathematicians working in probability, mathematical statisticians and computer scientists working in computer learning theory.
Alternatives to Animal Sera for Human Bone Marrow Cell Expansion: Human Serum and Serum-Free Media (1998)

The increasing use of cultured human cells in clinical trials is highlighting the need for alternatives to media containing animal sera that are typically used to support these cultures. Perfused cultures of BM mononuclear cells (MNC) were used to evaluate animal sera alternatives with respect to the output of primitive, progenitor, and stromal cells. A serum level of 20% was optimal, and this could be provided by FBS alone or by a mixture of horse serum (HoS) and FBS, but not by HoS alone. Allogeneic human plasma (20%) supported half the level of cell, CFU-GM, and LTC-IC output as compared with animal sera-containing control. Significant donor-to-donor variability in human plasma was observed, but this was mitigated by pooling of plasma samples. Autologous and allogeneic human plasma performed equivalently. The use of autologous or allogeneic human serum was found to be equivalent to the use of human plasma, but all were inferior to animal sera. Animal sera supported typical stroma and cobblestone formation, whereas stroma in human serum cultures was less dense. Eight commercial serum-free media were tested and found to support MNC expansion to varying degrees, but none approached the performance of the animal serum-containing control, particularly with respect to stromal (i.e., CFU-F) support. In fact, when MNC were cultured in parallel with CD34-enriched cells, output (from MNC) was higher only in control medium, apparently because serum-free media reduced accessory cell effects. Because of these results, a new serum-free medium was developed for MNC cultures. This formulation outperformed all commercial serum-free media, resulting in cell and LTC-IC output equivalent to that of control. However, CFU-GM and CFU-F output were 66% and 9% of control, respectively. Precoating the culture surface with collagen increased CFU-F (and Thy-1+ cell) output to control levels, although CFU-GM output was still lower than control. The addition of either fibronectin or PDGF had no measurable effect, nor did the use of 5-100-fold greater concentrations of growth factor supplementation. The serum-free medium also increased CD41+ and CD61+ cell output to 150%-220% of control levels. The development of this new serum-free medium has potential for use in the perfused BM MNC culture systems currently in clinical trials to test the efficacy of expanded cells after cytoablative chemotherapy.
