Multibeam, laser-imploded cylindrical plasmas (1986)

Four orthogonal line-focused 351-nm beams have been used to implode 2-mm-long, 100-\ensuremath{\mu}m-diam thin Al cylinders. The resulting linear, high-density, high-temperature plasma has characteristics suitable as an x-ray-laser medium.
Precision spectroscopy of pionic atoms and chiral symmetry in nuclei (2016)

We conduct an experimental project to make spectroscopy of deeply bound pionic atoms systematically over wide range of nuclei. We aim at studying the strong interaction in the low energy region, which has close connection to spontaneous chiral symmetry breaking and its partial restoration in nuclear matter. First experimental results show improved spectral resolution and much better statistical sensitivity than previous experiments. Present status of the experiment is reported.
Enhancement of Cancer Chemosensitization Potential of Cisplatin by Tea Polyphenols Poly(lactide-co-glycolide) Nanoparticles (2011)

Anti-cancer potential of polymer based nanoparticle of EGCG and TF alone and in combination with anti-cancer drug cisplatin have been studied in human cancer lines: A549 (lung carcinoma), HeLa (cervical carcinoma) and THP-1 (acute monocytic leukemia) using cell proliferation assay and cell cycle analysis. Encapsulated polyphenols retained biological effectiveness with over 20-fold dose advantage than EGCG/TF in exerting anti-cancer effects and also enhanced the potential of a widely used anti-cancer drug cisplatin. Subsequently, encapsulated polyphenols alone or in combination with cisplatin were more effective in inhibiting cell proliferation, metastasis, angiogenesis and apoptosis biomarkers. Collectively, our observations reveal that nanoparticle-mediated delivery of phytochemicals could serve as a basis for enhancing bioavailability and limiting the unwanted toxicity of chemotherapeutic agents.
Investigation of confinement effects in ZnO quantum dots (2009)

We report a simple method for the synthesis of Na(+) doped and stable zinc oxide quantum dots, using the quantum confinement atom method. An intense broad green photoluminescence (PL) was observed with a maximum located at approximately 535 nm when excited by UV radiation of 332 nm. The PL peak intensity is found to be highly dependent on the size of the quantum dots (QDs). Electron microscopy observation revealed that the radius of the QD was approximately 1 nm, which clearly indicated that the QDs are in the strong quantum confinement region (exciton Bohr radius, r(B), for bulk ZnO is 1.8 nm). Phase purity of ZnO and the presence of Na(+) was confirmed by x-ray diffraction (XRD) and atomic absorption spectroscopy (AAS), respectively. The results are well incremented by x-ray photoelectron spectroscopy (XPS) studies. Intentional ageing of QDs for several days under controlled experimental conditions such as temperature, relative humidity and pH etc, facilitated the formation of various nanostructures with a slight red shift in the PL peak position. Time resolved emission spectroscopy measurements indicated that PL decay time changes from 35 ns for QDs to 1660 micros for nanocrystals. The observed high-intensity and stable green PL emissions have been analyzed and thoroughly discussed.
Calcium Alginate Films: Thermal Properties and Permeability to Sorbate and Ascorbate (1996)

ABSTRACT Calcium alginate films were prepared by the pH‐controlled release of calcium ions into alginate solution or by the cooling of hot calcium alginate gels. Thermogravimetry and calorimetry showed that the controlled Ca release films contained a greater amount of high‐temperature component, and required extra energy to dissociate the tightly crosslinked calcium alginate. Structural differences were reflected by the permeability of the two films to potassium sorbate: 1.06 × 10 –7 (controlled Ca release) and 1.58 × 10 –7 cm 2 sec –1 (cooled). Apparent activation energy was estimated to be for the diffusion of potassium sorbate 24.1 KJ·mol –1 , sodium ascorbate 23.7, and ascorbic acid 36.2. Results suggested that the pH of the diffusant solution had an interactive effect on the alginate film.
Terahertz time-domain spectroscopy using a power detector (2013)

We here demonstrate the ability of a power detector implemented with a Michelson interferometer to perform spectral analysis in the THz range. Both analytical and experimental investigations are performed in the time domain. The polarization state of the impinging beam has been optimized and interfero-gram measurements are in a good agreement with the expected ones. Spectral response and spatial distribution (2D mapping) of the measurement bench have been characterized. Thanks to the wide bandwidth and a measurement dynamics of 40 dB, material spectroscopy and terahertz power detector analysis has been demonstrated.
Verifying the SET registration protocols (2003)

Secure electronic transaction (SET) is an immense e-commerce protocol designed to improve the security of credit card purchases. In this paper, we focus on the initial bootstrapping phases of SET, whose objective is the registration of cardholders and merchants with a SET certificate authority. The aim of registration is twofold: getting the approval of the cardholder's or merchant's bank and replacing traditional credit card numbers with electronic credentials that cardholders can present to the merchant so that their privacy is protected. These registration subprotocols present a number of challenges to current formal verification methods. First, they do not assume that each agent knows the public keys of the other agents. Key distribution is one of the protocols' tasks. Second, SET uses complex encryption primitives (digital envelopes) which introduce dependency chains: the loss of one secret key can lead to potentially unlimited losses. Building upon our previous work, we have been able to model and formally verify SETs registration with the inductive method in Isabelle/HOL (T. Nipkow et al., 2002). We have solved its challenges with very general techniques.
MultiAmdahl: How Should I Divide My Heterogenous Chip? (2012)

Future multiprocessor chips will integrate many different units, each tailored to a specific computation. When designing such a system, a chip architect must decide how to distribute the available limited system resources, such as area and power, among all the computational units.In this paper, we introduce MultiAmdahl, an analytical optimization technique for resource sharing among heterogeneous units. MultiAmdahl takes into account the workload, the performance of each computational unit, and the total available resource. The results obtained by MultiAmdahl allow us, for example, to provide a closed-form solution for an optimal asymmetric-offload chip, and to analyze the impact of different design constraints on an optimal chip architecture.
A new boundary element technique without domain integrals for elastoplastic solids (2005)

Abstract A simple idea is proposed to solve boundary value problems for elastoplastic solids via boundary elements, namely, to use the Green's functions corresponding to both the loading and unloading branches of the tangent constitutive operator to solve for plastic and elastic regions, respectively. In this way, domain integrals are completely avoided in the boundary integral equations. Though a discretization of the region where plastic flow occurs still remains necessary to account for the inhomogeneity of plastic deformation, the elastoplastic analysis reduces, in essence, to a straightforward adaptation of techniques valid for anisotropic linear elastic constitutive equations (the loading branch of the elastoplastic constitutive operator may be viewed formally as a type of anisotropic elastic law). Numerical examples, using J 2 ‐flow theory with linear hardening, demonstrate that the proposed method retains all the advantages related to boundary element formulations, is stable and performs well. The method presented is for simplicity developed for the associative flow rule; however, a full derivation of Green's function and boundary integral equations is also given for the general case of non‐associative flow rule. It is shown that in the non‐associative case, a domain integral unavoidably arises in the formulation. Copyright © 2005 John Wiley & Sons, Ltd.
Accurate 3D kinematic measurement of temporomandibular joint using X-ray fluoroscopic images (2014)

Accurate measurement and analysis of 3D kinematics of temporomandibular joint (TMJ) is very important for assisting clinical diagnosis and treatment of prosthodontics and orthodontics, and oral surgery. This study presents a new 3D kinematic measurement technique of the TMJ using X-ray fluoroscopic images, which can easily obtain the TMJ kinematic data in natural motion. In vivo kinematics of the TMJ (maxilla and mandibular bone) is determined using a feature-based 2D/3D registration, which uses beads silhouette on fluoroscopic images and 3D surface bone models with beads. The 3D surface models of maxilla and mandibular bone with beads were created from CT scans data of the subject using the mouthpiece with the seven strategically placed beads. In order to validate the accuracy of pose estimation for the maxilla and mandibular bone, computer simulation test was performed using five patterns of synthetic tantalum beads silhouette images. In the clinical applications, dynamic movement during jaw opening and closing was conducted, and the relative pose of the mandibular bone with respect to the maxilla bone was determined. The results of computer simulation test showed that the root mean square errors were sufficiently smaller than 1.0 mm and 1.0 degree. In the results of clinical application, during jaw opening from 0.0 to 36.8 degree of rotation, mandibular condyle exhibited 19.8 mm of anterior sliding relative to maxillary articular fossa, and these measurement values were clinically similar to the previous reports. Consequently, present technique was thought to be suitable for the 3D TMJ kinematic analysis.
Cellular consequences of transthyretin deposition (2003)

Mutant forms of transthyretin (TTR) deposit in tissues of patients presenting with familial amyloidotic polyneuropathy (FAP). The cellular consequences of tissue TTR deposition have only been addressed recently and are summarized here. Inflammatory and oxidative stress pathways are triggered by fibrillar and non-fibrillar TTR deposits, a fact to take into account in future forms of FAP treatment.

A simple minimum rate supporting scheduler for UTRA/TDD high speed downlink packet access (2004)

A minimum rate supporting scheduler (MRSS) is proposed in this paper. MRSS guides the user selection in order to provide, if any, a prespecified minimum rate for each user. The minimum rate, however, is not always guaranteed especially when the traffic offered in downlink is heavy or excessive. In this case, additional call admission control is necessary, which falls outside the scope of the present paper. MRSS is numerically evaluated to show to what extent of the offered traffic the scheduler could provide the minimum rate. A main advantage of MRSS is its simplicity. MRSS causes little attendant increase in complexity compared to proportional fairness rate scheduler (PFRS) that is currently implemented in cdma2000 1xEV. Thus, MRSS is also implementable. Numerical evaluation of the performance for MRSS is done under UTRA/TDD HSDPA environments. The results show that it support to keep the minimum rate up to fairly high traffic load where existing methods fail and achieves better throughput than PFRS. Therefore, MRSS is a simple, minimum rate supporting and performance-enhanced scheduler that is possibly used in practical 3G mobile system.
Applying the Occupational Safety and Health Administration (OSHA) ultrasonic noise ceiling values. (2008)

The Occupational Safety and Health Administration (OSHA) voted in 2003 to accept the American Conference of Governmental Industrial Hygienists (ACGIH) increased threshold level values (TLVs) for airborne ultrasound from the more stringent levels set previously as a result of ultrasonic sickness studies reported in the 1960s. The impedance mismatch between the air and the body, which prevents most ultrasonic energy absorption, was the rationale. The TLVs were increased by 30 dB, unless solid or liquid coupling is possible, allowing the unintended transfer of acoustic energy into the worker. The TLVs were set based on two lines of evidence: (1) detectability of directly coupled ultrasound and damage reported from ultrasonic exposure. The risk of ultrasonic exposure underwater is also addressed in direct coupling to an ultrasonic source. The measurements needed are airborne sound pressure level up to 100 kHz, waterborne sound pressure up to 100 kHz, and high frequency vibration. Only a 2–5 dB threshold shift for 13–17 kHz for over three years has been reported after airborne exposure. The eye was found to be a window into the skull for ultrasonic energy, reducing the impedance mismatch to 33 dB, weakening the argument that high skin impedance is an acceptable barrier.
Linear Lists (2016)

In our first steps as programmers, we often write short programs with a quite limited number of variables. Very soon, however, the programming tasks get more involved, and we need some advanced tools to manage efficiently the increasing number of elements dealt with by our programs. This is the role of what has become known as Data Structures, which are the subject of this book.
Effects of Age on Long Term Memory for Degraded Speech (2016)

Prior research suggests that acoustical degradation impacts encoding of items into memory, especially in elderly subjects. We here aimed to investigate whether acoustically degraded items that are initially encoded into memory are more prone to forgetting as a function of age. Young and old participants were tested with a vocoded and unvocoded serial list learning task involving immediate and delayed free recall. We found that degraded auditory input increased forgetting of previously encoded items, especially in older participants. We further found that working memory capacity predicted forgetting of degraded information in young participants. In old participants, verbal IQ was the most important predictor for forgetting acoustically degraded information. Our data provide evidence that acoustically degraded information, even if encoded, is especially vulnerable to forgetting in old age.

Dynamic Secretin-enhanced MR Cholangiopancreatography (2006)

Secretin causes temporary dilatation of pancreatic ducts, principally by increasing pancreatic exocrine secretions, and thus allows better visualization of the ducts at magnetic resonance (MR) cholangiopancreatography. Secretin-enhanced MR cholangiopancreatography is useful for detection and diagnosis of a variety of congenital, inflammatory, and neoplastic conditions of the pancreas. Although MR cholangiopancreatography without secretin is a reliable method for evaluating the pancreatobiliary ductal system, the authors believe that secretin-enhanced MR cholangiopancreatography gives additional valuable functional and anatomic information about the pancreatic duct and pancreatic excretory capacity.
Changes of lipid peroxidation in mouse brain crude synaptosomal preparations in relation to the development and disappearance of tolerance to ethanol. (1983)

A single dose of ethanol induced a bimodal increase of Fe++- and ascorbic acid-stimulated lipid peroxidation in mouse brain crude synaptosomal preparations. This effect of ethanol was lost in preparations from ethanol tolerant animals and reappeared when the animals recovered from tolerance after withdrawal from ethanol treatments. The parallel changes in lipid peroxidation of brain crude synaptosomal preparations with the development and disappearance of tolerance to ethanol imply that the effect of ethanol on brain lipid may be directly associated with its mechanism in the CNS.
Ultrafast switching in AlGaAs waveguide devices (1992)

Theoretical modeling of the nonresonant nonlinearity in semi- conductors has predicted an enhancement in n 2 in the spectral region of half the band gap. We have fabricated and tested a range of nonlinear switching devices in AlGaAs. The material contained 18% Al, sufficient to shift the fundamental band gap to λ g = 0.75 μm and, consequently, the half band gap to 1.5 μm. Thus, working in the 1.55 μm spectral region allowed purely refractive effects to be observed, without the detrimental effects of two-photon absorption. We have experimentally observed ultrafast switching in directional couplers and integrated asymmetric Mach–Zehnder interferometers. The switching speed was <100 fs, with peak powers in the 200 W range and the experimentally determined values for n 2 in the region of 1 × 10 -13 cm 2 W -1 . Because of the nonresonant nature of the nonlinearity, devices had a high throughput at 30%. We will present a range of experimental data on the materials and devices tested.

Design considerations and text selection for BREF, a large French read-speech corpus (1990)

BREF, a large read-speech corpus in French has been designed with several aims: to provide enough speech data to develop dictation machines, to provide data for evaluation of continuous speech recognition systems (both speaker-dependent and speaker-independent), and to provide a corpus of continuous speech to study phonological variations. This paper presents some of the design considerations of BREF, focusing on the text analysis and the selection of text materials. The texts to be read were selected from 4.6 million words of the French newspaper, Le Monde. In total, 11,000 texts were selected, with an emphasis on maximizing the number of distinct triphones. Separate text materials were selected for training and test corpora. The goal is to obtain about 10,000 words (approximately 60-70 min.) of speech from each of 100 speakers, from different French dialects.
Immunochemical Technology in Environmental Analysis (1989)

Immunochemical technology is at a critical stage in its development for use in environmental analysis. Primary problems and issues regarding assay development and applications such as outlining common misconceptions, choice of format and choice of monoclonal or polyclonal antibodies are discussed. More far reaching concerns for the acceptance of the technology such as the roles of government and industry in assay development and standardization are also discussed. A committee to coordinate the development of immunoassay in the environmental field is proposed and its functions outlined. How some of these problems are currently being addressed are illustrated by work presented at this symposium. Work from our laboratory illustrates our approach to dealing with real world samples, more difficult target compounds and complex matrices and applying immunoassays to samples other than environmental samples.
Fenobarbital Uygulamasında Intravenöz ve Intraosseöz Yolların Karşılaştırılması (1999)

SüleymanDemirel Üniversitesi TIP FAKÜLTESİ DERGİSİ: 1999 Aralık; 6(4) Fenobarbital Uygulamasında Intravenöz ve Intraosseöz Yolların Karşılaştırılması Ruşen Dündaröz, Turner Türkbay, Ali Sızlan, Tuncer Değim, Faysal Gök, Tahir Özışık ÖzetStatus epileptikus klasik olarak 30 dakikadan uzun süren jenaralize tonik-klonik nöbet olarak tarif edilir. Uzun süren nöbet aktivitesi irreversibl serebral hasar ile sonuçlanabilir. Üstelik, nöbet aktivitesinin uzun sürmesinin kontrol edilebilirliğini azalttığı yönünde kanıtlar vardır. Damar yolunun sağlanması nöbet esnasında sıklıkla zordur. Öte yandan intraosseöz yol (IO) kullanıma hazırdır. Bu ça¬lışmada, 20 mg/kg dozunda fenobarbital IV ve IO yoldan tavşanlara uygulandı. Fenobarbital kan düzey¬leri ölçüldü ve sonuçlar karşılaştırıldı. Fenobarbital plazma profilinin IO uygulamada terapötik seviyede olduğu görüldü. IO yolun fenobarbital verilmesinde IV yola alternatif olabileceği sonucuna varıldı. Anahtar Kelimeler: Fenobarbital, kemik iliği infüzyonu, intraosseöz infüzyon, intravasküler giriş, status epileptikus AbstractComparison of Intravenous and Intraosseous Routes for The Administration ofPhenobarbital Status epilepticus (SE) is classically defined as a generalized tonic-clonic seizure lasting longer than 30 min. Prolonged seizure activity can result in irreversible cerebral injury. In addition, evidence suggests that the longer the duration of the seizure, the less likely the activity is to be controlled. IV access, however, is frequently difficult to achieve during the seizure. On the other hand, intraosseous (IO) access is available. In this study, phenobarbital was administered to rabbits using both IV and IO lines at the dose of 20 mg/kg. The levels of phenobarbital in the blood were measured and the results were compared. The plasma profile of phenobarbital was found to be in the therapeutic level when it was administered by IO route. It was concluded that the IO line appeared to be an alternative route to IV access in the administration of phenobarbital. Key Words: Phenobarbital, bone marrow infusion, intraosseous infusion, intravascular access, status epilepticus
