Electroencephalographic Study of Essential Oils for Stress Relief (2013)

Nowadays, electroencephalogram (EEG) is widely used in medical applications. Besides the examination for brain diseases, EEG is used to observe how the surroundings affect peoples emotion. There are many essential oils, and most claim that they are effective in soothing soul and calming. Currently, there is no related EEG scientific experiment to verify this claim, This study attempted to understand whether common essential oils for stress relief have actual emotional relaxation effects on the human brain by EEG observation; the level of efficacy was also observed. From the results of this study, rose essential oil had the best effect of stress relief and relaxation in both genders ( P &lt;0.05). It suggested that peppermint essential oil had the best effect of relaxation in male ( P &lt;0.05) and rose essential oil had the best effect of relaxation in females ( P &lt;0.05) when it was analyzed by gender.
Fractional Quantum Hall Hierarchy and the Second Landau Level (2007)

We generalize the fractional quantum Hall hierarchy picture to apply to arbitrary, possibly non-Abelian, fractional quantum Hall states. Applying this to the nu = 5/2 Moore-Read state, we construct new explicit trial wavefunctions to describe the fractional quantum Hall effect in the second Landau level. The resulting hierarchy of states, which reproduces the filling fractions of all observed Hall conductance plateaus in the second Landau level, is characterized by electron pairing in the ground state and an excitation spectrum that includes non-Abelian anyons of the Ising type. We propose this as a unifying picture in which p-wave pairing characterizes the fractional quantum Hall effect in the second Landau level.
TRAPEZ SACLARIN TİTREŞİM DAVRANIŞLARININ SONLU ELEMANLAR VE DENEYSEL MODAL ANALİZLERİYLE İNCELENMESİ (2021)

Günümüzde çoğunlukla prefabrik yapılarda, çatılarda, konteynerlerde, baraka ve depo gibi yapıların imalatında kullanılan trapez saclar farklı ölçü ve kalınlıklar ile yapısal dayanım ihtiyaçlarını karşılayabilmektedir. İçerisine jeneratör gibi çalışan bir makine yerleştirildiğinde ise dinamik etkiler ortaya çıkmakta ve standart trapez profillerinin yetersiz kalmasına neden olmaktadır. Titreşim ve akustik özelliklerinin de ön plana çıktığı bu tip yapılarda dinamik açıdan da gereksinimlerin karşılanması gerekmektedir. Bu çalışmada, istenen dinamik davranışın elde edilebilmesi için farklı trapez sac kesit geometrileri ve kalınlıkları ile karşılaştırmalı çalışmalar yapılmıştır. Bu trapez geometrilerinin istenen kriterlere uygunluğu, bilgisayar ortamında sonlu elemanlar analizleri yapılarak; doğrulama çalışması ise üretilen numune üzerinden deneysel modal analiz testi yapılarak gerçekleştirilmiştir. Bu çalışmada farklı trapez sac geometrileri için sonlu elemanlar analizleri yapılmıştır. Sonlu elemanlar analizlerini desteklemek amacıyla deneysel modal analiz yapılarak sonuçların örtüştürülmesi amacıyla gerekli çalışmalar gerçekleştirilmiştir.
Reducing Web latency using reference point caching (2002)

To reduce Web access latencies, we propose a new paradigm for caching at the reference point of a document. If a document X is referred to from a document Y, information is cached at Y to reduce the latency of client accesses to X. We focus on two specific instances of this paradigm: caching IP addresses to avoid DNS lookups at clients, and caching information about documents to avoid setting up new connections. Avoiding DNS lookup saves over 4 seconds 10-12% of the time and avoiding connection setup saves 240 ms on the average. These ideas enable new services such as search engines that return IP addresses to speed up search sessions, and caching at regional information servers that goes beyond the capabilities of today's proxy caching.
Estrogen Abrogates Transcervical Tight Junctional Resistance by Acceleration of Occludin Modulation (2004)

The present study explored the effects of estrogen on transcervical tight-junctional resistance (R(TJ)) and the mechanisms involved. Treatment of cultured human cervical epithelial cells with 17beta-estradiol decreased in a time- and dose-related manner the R(TJ). Estrogen had no significant effect on the expression of E-Cadherin, zonula-occluden-1, or Claudin-4. In contrast, 17beta-estradiol modulated expression of the transmembrane tight-junctional protein occludin: at low concentrations (1 and 10 nm) estradiol increased the density of occludin 65-kDa form but at the higher concentration of 100 nm estradiol induced only a mild 2-fold increase in the density of this form. Estradiol also increased the expression of occludin 50-kDa form in a dose-related manner. The R(TJ) and occludin effects of estradiol were reversible and could be blocked by tamoxifen but not progesterone. The present results rule out estrogen modulation of occludin transcription. In contrast, the results suggest that the occludin effects of estrogen involve posttranslational up-regulation of occludin turnover, including synthesis and degradation. The effects of estrogen on occludin expression were compared with those of proteinase-K, plasmin, and matrix-metaloproteinase-2 (all added extracellularly). The three proteinases abrogated irreversibly the R(TJ) and induced expression de novo of occludin low-molecular-weight forms. The latter, however, differed from the effect of estrogen, which generated only a single 50-kDa form. Collectively, the present data suggest that the occludin 50-kDa form is an estrogen-specific-induced occludin isoform and that the mechanism of estrogen-abrogation of transcervical R(TJ) involves occludin modulation.
Physical characteristics of indigestible solids affect emptying from the fasting human stomach. (1989)

Gastric emptying of indigestible solids depends on their size. It is not clear whether physical characteristics other than particle size affect emptying of indigestible solids from the fasting human stomach. We studied gastric emptying of three differently shaped particles, (cubes, spheres, rods) of either hard or soft consistency during the fasting state in human volunteers. The shape of indigestible particles did not affect their emptying. The area under the gastric emptying curve (AUC: particles x hour) was for hard cubes 24.7 (2.2), for hard spheres 27.9 (1.6), for hard rods 26.9 (2.7). All soft particles emptied faster than their identically shaped hard counterparts, but there was no difference among the three shapes (AUC for soft cubes: 29.2 (3.0), for soft spheres 32.0 (1.8), for soft rods 34.1 (1.2). If gastric emptying of hard and soft particles was compared independently of their shape, soft particles emptied significantly faster than hard ones: AUC 31.8 (1.2) v 26.5 (1.3) (p less than 0.01). In conclusion, the consistency but not the shape significantly affects gastric emptying. Specific physical characteristics other than size and shape may affect gastric emptying of indigestible particles which may be of importance in the design of drugs.

Sound transmission in the lung as a function of lung volume (2002)

We were interested in how the transmission of sound through the lung was affected by varying air content in intact humans as a method of monitoring tissue properties noninvasively. To study this, we developed a method of measuring transthoracic sound transit time accurately. We introduced a "coded" sound at the mouth and measured the transit time at multiple microphones placed over the chest wall by using a 16-channel lung sound analyzer (Stethographics). We used a microphone placed over the neck near the trachea as our reference and utilized cross-correlation analysis to calculate the transit times. The use of the coded sound, composed of a mix of frequencies from 130 to 150 Hz, greatly reduced the ambiguity of the cross-correlation function. The measured transit time varied from 1 ms at the central locations to 5 ms at the lung bases. Our results also indicated that transit time at all locations decreased with increasing lung volume. We found that these results can be described in terms of a model in which sound transmission through the lung is treated as a combination of free-space propagation through the trachea and a propagation through a two-phase system in the parenchyma.

Reflectance Modeling for Real Snow Structures Using a Beam Tracing Model (2008)

It is important to understand reflective properties of snow, for example for remote sensing applications and for modeling of energy balances in snow packs. We present a method with which we can compare reflectance measurements and calculations for the same snow sample structures. Therefore, we first tomograph snow samples to acquire snow structure images (6 x 2 mm). Second, we calculated the sample reflectance by modeling the radiative transfer, using a beam tracing model. This model calculates the biconical reflectance (BR) derived from an arbitrary number of incident beams. The incident beams represent a diffuse light source. We applied our method to four different snow samples: Fresh snow, metamorphosed snow, depth hoar, and wet snow. The results show that (i) the calculated and measured reflectances agree well and (ii) the model produces different biconical reflectances for different snow types. The ratio of the structure to the wavelength is large. We estimated that the size parameter is larger than 50 in all cases we analyzed. Specific surface area of the snow samples explains most of the difference in radiance, but not the different biconical reflectance distributions. The presented method overcomes the limitations of common radiative transfer models which use idealized grain shapes such as spheres, plates, needles and hexagonal particles. With this method we could improve our understanding for changes in biconical reflectance distribution associated with changes in specific surface area.
A Variable (n/m)X Switched Capacitor DC–DC Converter (2016)

High gain bidirectional dc-dc converter with high efficiency and high power density is a much desired circuit in any converter/inverter system. It is well known that switched capacitor circuits that are variants of the Dickson converter are suitable candidates for such a system. Modular design, absence of external magnetic components, and high efficiency are some of the features that make them suitable candidates. But, the inability to provide fractional and variable voltage gains at high efficiency during normal operation severely limits their application. It also leads to higher voltage stress in the overall system. The aim of this paper is twofold. First, a generalized modular switched capacitor converter, the “(n/m)X converter,” which is a variant of the original Dickson converter is introduced. Using this generalized configuration, the converter can be designed for a required fractional gain. Next, two different methods to enable dynamic variation in gain with high efficiency using the (n/m)X converter are proposed. Detailed analysis, design steps, equivalent circuits, and experimental results for a 1 kW prototype of a variable (4/0.5)X boost converter validate the proposed theory. A peak measured efficiency of over 95% is achieved for the prototype. The design framework and analysis in this paper can be extended to a generic (n/m)X converter.
Evidence for lysine 80 as general base catalyst of leucine dehydrogenase. (1993)

To elucidate the functional role of the lysyl residue highly conserved in NAD(P)(+)-dependent amino acid dehydrogenases, Lys-80 of leucine dehydrogenase from Bacillus stearothermophilus has been mutated into Ala, Arg, or Gln. All of the mutant enzymes had markedly reduced activities in the oxidative deamination, whereas the Michaelis constants for substrate and coenzyme did not change significantly upon the mutation, except for a 10-30-fold increase in Km values for alpha-keto-iso-caproate in the Ala and Gln mutants. The pH profiles of kinetic parameters of the mutants considerably differed from those of the wild type, in which two ionizable groups with pKa values of 8.9 and 10.7 must be unprotonated for catalysis and protonated for substrate binding, respectively. Combined with the analyses of solvent isotope effect and inhibition by substrate analogs, these results unequivocally show that the epsilon-amino group of Lys-80 participates in catalysis as a general base, assisting the nucleophilic attack of a water molecule to the substrate alpha-carbon atom. Furthermore, the Ala mutant was markedly stimulated by primary amines depending on the pKa and molecular volume, suggesting that in the Ala mutant the added amines can partially replace the general base function of Lys-80 in the wild type enzyme.
Enhanced photo‐bioelectrochemical energy conversion by genetically engineered cyanobacteria (2015)

Photosynthetic energy conversion using natural systems is increasingly being investigated in the recent years. Photosynthetic microorganisms, such as cyanobacteria, exhibit light-dependent electrogenic characteristics in photo-bioelectrochemical cells (PBEC) that generate substantial photocurrents, yet the current densities are lower than their photovoltaic counterparts. Recently, we demonstrated that a cyanobacterium named Nostoc sp. employed in PBEC could generate up to 35 mW m(-2) even in a non-engineered PBEC. With the insights obtained from our previous research, a novel and successful attempt has been made in the current study to genetically engineer the cyanobacteria to further enhance its extracellular electron transfer. The cyanobacterium Synechococcus elongatus PCC 7942 was genetically engineered to express a non-native redox protein called outer membrane cytochrome S (OmcS). OmcS is predominantly responsible for metal reducing abilities of exoelectrogens such as Geobacter sp. The engineered S. elongatus exhibited higher extracellular electron transfer ability resulting in approximately ninefold higher photocurrent generation on the anode of a PBEC than the corresponding wild-type cyanobacterium. This work highlights the scope for enhancing photocurrent generation in cyanobacteria, thereby benefiting faster advancement of the photosynthetic microbial fuel cell technology.
Towards an Indoor Testbed for Mobile Networked Control Systems (2011)

In this paper, we consider the design of an indoor testbed composed of multiple aerial and ground unmanned vehicles for experimentation in Mobile Networked Control Systems. Taking several motivational aspects from both research and education into account, we propose an architecture to cope with the scale and mobility aspects of the overall system. Currently, the testbed is composed of several low-cost ARdrones quadrotors, small-scale heavy duty vehicles, wireless sensor nodes and a vision-based localization system. As an example, the automatic control of an ARdrone is shown.
Detection of foreign body using fast thermoacoustic tomography with a multielement linear transducer array (2007)

Current imaging modalities face challenges in clinical applications due to limitations in resolution or contrast. Microwave-induced thermoacoustic imaging may provide a complementary modality for medical imaging, particularly for detecting foreign objects due to their different absorption of electromagnetic radiation at specific frequencies. A thermoacoustic tomography system with a multielement linear transducer array was developed and used to detect foreign objects in tissue. Radiography and thermoacoustic images of objects with different electromagnetic properties, including glass, sand, and iron, were compared. The authors' results demonstrate that thermoacoustic imaging has the potential to become a fast method for surgical localization of occult foreign objects.
CuSO4/H2O2‐Induced Rapid Deposition of Polydopamine Coatings with High Uniformity and Enhanced Stability (2016)

Mussel-inspired polydopamine (PDA) deposition offers a promising route to fabricate multifunctional coatings for various materials. However, PDA deposition is generally a time-consuming process, and PDA coatings are unstable in acidic and alkaline media, as well as in polar organic solvents. We report a strategy to realize the rapid deposition of PDA by using CuSO4/H2O2 as a trigger. Compared to the conventional processes, our strategy shows the fastest deposition rate reported to date, and the PDA coatings exhibit high uniformity and enhanced stability. Furthermore, the PDA-coated porous membranes have excellent hydrophilicity, anti-oxidant properties, and antibacterial performance. This work demonstrates a useful method for the environmentally friendly, cost-effective, and time-saving fabrication of PDA coatings.
A new method for accurate platelet thrombi volume measurement using a confocal microscope (2019)

&lt;p class="Abstract"&gt;The accuracy of quantitative measurements represents an essential pre-requisite to the characterization and definition of the complex dynamic phenomena occurring in the field of cell biology. In research projects that involve the induction of blood coagulation under flow in microfluidic artificial channels, thrombus volume is an important quantity for estimation as a significant index related to the individual thrombotic risk profile. Concerning its importance in the early diagnosis of cardiovascular diseases, the estimated thrombus volume should reflect and represent reality. In 3D confocal microscopy, systematic errors can arise from distortions of the axial distance, whose accurate calibration remains a challenge. As a result, the 3D reconstructions show a noticeable axial elongation, and the volume measurements are thus overestimated. In this paper, a 400-600 % volume overestimation is demonstrated, and a new easy to use and automatic calibration procedure is outlined for this specific microfluidic and optical context. The adaptive algorithm proposed leads to the automatic compensation of the elongation error and to the accurate thrombus volume measurement. The method has been calibrated using fluorescent beads of known volume, validated with groups of several distinct platelets and finally applied on platelet thrombi.&lt;/p&gt;
Purification and thermodynamic characterization of glucose oxidase from a newly isolated strain ofAspergillus niger (2006)

An intracellular glucose oxidase (GOD) was isolated from the mycelium extract of a locally isolated strain of Aspergillus niger NFCCP. The enzyme was partially purified to a yield of 28.43% and specific activity of 135 U mg(-1) through ammonium sulfate precipitation, anion-exchange chromatography, and gel filtration. The enzyme showed high specificity for D-glucose, with a K(m) value of 25 mmol L(-1). The enzyme exhibited optimum catalytic activity at pH 5.5. Optimum temperature for GOD-catalyzed D-glucose oxidation was 40 degrees C. The enzyme displayed a high thermostability having a half-life (t(1/2)) of 30 min, enthalpy of denaturation (H*) of 99.66 kJ mol(-1), and free energy of denaturation (G*) of 103.63 kJ mol(-1). These characteristics suggest that GOD from A. niger NFCCP can be used as an analytical reagent and in the design of biosensors for clinical, biochemical, and diagnostic assays.

Data Theft Prevention and Endpoint Protection from PnP Devices (2012)

Podslurping is the intentional or unintentional use of a portable USB mass storage device, such as a USB flash drive (or “thumb drive”), to illicitly download and store confidential and proprietary data from network endpoint.[1] Many organizations are unaware of, or choosing to ignore, the threat presented by portable devices in their network environment until some event, ranging from unfortunate to catastrophic, happens. In hard economic times, cybercrime and data leakage increase, finding an easy target in endpoints. The key to managing portable devices in business environment is to give administrator direct control over what devices are in use on your network. In this paper we present the need and implementation of access and identity management for endpoint protection and data security from PnP USB devices to maintain information security in a corporate network. General Terms Endpoint protection; Data security; IT security; Data theft prevention; Access and identity management.
