Nacionalni obrazovni standard – instrument kontroliranja učinkovitosti obrazovnog sustava, unapređivanja kvalitete nastave ili standardiziranja razvoja osobnosti? (2007)

U radu se polazi od analize znacenja oksimorona “obrazovni standardi” kojim se želi skrenuti pozornost na novi tip standarda, koji se razlikuju od dosadasnjih pedagoskih standarda prema tome sto se odnose na izlaz (output) i u nacionalnom okviru preciziraju kako taj izlaz treba izgledati (modeli kompetencija, test-zadaci). Kriticko je razmatranje koncepta obrazovnih standarda poduzeto u namjeri da se pokrene strucno-pedagoska rasprava o tome vodi li ovaj nacin koncipiranja odgojno-obrazovnih ciljeva do nove kulture ucenja i poducavanja ili obrazovni sustav vodi prema racionalno planiranom poduzetnistvu, apsolutiziranju određenih formi tehnoloski osigurane nastave i duhovnog osiromasivanja ucenika. Namjera nije osporiti potrebu postavljanja (i provjeravanja) standarda u podrucju obrazovanja, nego problematizirati standarde ucenickih postignuca (output paradigmu) kao ekonomsko-funkcionalisticki instrument kontrole ucinkovitosti sustava i istaknuti (jos uvijek bezglasnu) pedagosku perspektivu u smislu standarda uvjeta skolskog ucenja, standarda pedagoskog djelovanja, standarda okvirnih skolskih, odnosno standarda sustavnih uvjeta. Osnovna misao tih standarda je da uvjete i oblike skolskog rada i ucenja treba smisleno, planski poboljsati, pri cemu ce se investirati u skolske materijalne uvjete, kvalitetu iskustava ucenja, kao i u samoobrazovanje i samoorganizirano ucenje, posebno ucitelja (nastavnika, profesora) kao osnovnog agensa svih reformi obrazovnog sustava i sukreatora nove nastavne kulture
Implementing Sparc in ECL (1990)

A joint development project that implemented Sun Microsystems' scalable processor architecture (Sparc) with Bipolar Integrated Technology's bipolar emitter-coupled logic (ECL) is described. The authors review both ECL technology and the features of BIT's ECL technique and discuss how board and cache considerations influenced the chip designs. Also discussed are the integer unit pipeline, system interface signals, and coprocessor interface. The chip set, now completed, performs at a level equal to large mainframe computers and approaches that of today's supercomputers.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

A rapid HPLC method for the determination of lactoferrin in milk of various species (2019)

This Research Communication describes the adaptation and testing of an RP-HPLC method, previously tested for the determination of lactoferrin (LF) in whey, for its applicability to determine milk lactoferrin content. Milk samples of various species, namely, ovine, caprine, bovine, donkey and human milk, were tested. The advantage of this RP-HPLC method includes speed and convenience, as it does not include extensive pretreatment or separation steps. A simple pre-treatment step was added in order to remove fat and proteins of the casein family and the samples were tested. The results varied in terms of elution of the LF peak both between the milk of the different species as well as from the initial application on whey. The peak resolution was satisfactory in the cases of ovine, bovine and donkey milk samples while for caprine and human milk an interference with other peaks was observed. Nevertheless, quantification of LF was found possible for all samples. This new application of the modified method will allow the determination of LF in milk samples of the tested species either for everyday analysis or as a useful qualitative screening for presence or absence of LF.
Design of a digital send-site synchronizing and deskewing circuit for multi-lane serial high-speed communication (2010)

As an approach to the prevailing synchronization deficiencies inherent in skew-sensitive multi-channel high-speed data transmission the design of a digital synchronizing and deskewing circuit on the part of the transmitter side is described. It is based on a concept of accurate skew determination on the physical outputs by a chained per-lane feedback.
Integrated Solar Array and Reflectarray Antenna for High Bandwidth Cubesats (2015)

The Integrated Solar Array and Reflectarray Antenna (ISARA) mission will demonstrate a reflectarray antenna that increases downlink data rates for Cube- Sats from the existing baseline rate of 9.6 kilobits per second (kbps) to more than 100 megabits per second (Mbps). The ISARA spacecraft is slated for launch no earlier than Dec. 1, 2015.
'ACTIVATED' ALUMINUM AS A STORED ENERGY SOURCE FOR PROPELLANTS (1997)

The process of electro-explosion of metal wires, which has been known for more than 200 years, has been adapted to the preparation of activated aluminum, called Alex. The process produces metallic particles of approximately 50−100 nanometers in size. X-ray diffraction studies both in Russia and the U.S.A. confirm the crystallites are aluminum, although one study shows a minor amount of an unknown phase, that is presumed to be oxide. The surface phase appears to be semiconductive in nature. The most unusual characteristic of this aluminum is the stored energy that is released upon reaching a threshold temperature. While this heat generation has been confirmed by other researchers, no one, including the authors has a proven theory for the source of this energy. Nevertheless, this material is suggested for use as a fuel in pyrotechnics, explosives and propellants.
In vitro ocular irritancy measure of four contact lens solutions: damage and recovery. (1995)

We measured the potential toxicity of four contact lens solutions using an in vitro approach in which the optical quality of the cultured bovine lens was measured as a function of exposure to each substance tested. This approach uses an automated scanning laser to measure the focal variability of lenses contained in special culture cells and maintained under long-term culture conditions. The products tested included three rigid gas permeable contact lens conditioning solutions (Boston Conditioning Solution, Boston Advance Conditioning Solution, and a new formulation of Boston Advance Conditioning Solution [Polymer Technology]) and one soft contact lens disinfecting system (OptimEyes; Core Technologies). The results indicate a wide range of toxicologic potential that corresponds, on a relative basis, with published in vivo evaluation of the same substances. Moreover, the results demonstrate that this in vitro system can be used to evaluate the potential for recovery from damage caused by the four solutions tested.
Micro-doppler signal estimation for vibrating and rotating targets (2006)

Vibrations or rotations of a target or structures on a target give rise to the micro-Doppler effect of the reflected waveforms. In this paper, we analyze micro- Doppler signals in the joint time-frequency plane using commonly applied distributions and time-frequency transforms. Performance is evaluated based on achieved resolution and reduced artifacts. The latter is significant in microDoppler analysis, as the signals have sinusoidal timefrequency (TF) signatures. This presents a challenge for the already established distributions, as they have to suppress the cross as well as the auto artifacts. We propose a new decomposition of basis functions, given the apriori knowledge of the time varying nature of the radar returns. This approach can be cast as an application of waveform diversity. The new decomposition is free from any artifacts and provides improved estimates of the target micro-Doppler signature.

People with Differences of Sexual Development: Can We Do Better? (2021)

This article discusses how careproviders of all types can help people with differences of sexual development (DSD): people with ambiguous genitalia, who used to be referred to as intersexed. Careproviders may be in a unique position to benefit these people by offering to discuss difficult issues that concern them, even when the discussions are brief. Specific interventions include learning about people with DSD, whether through the literature or in the clinic; treating them with optimal respect; raising difficult topics such as sex, fertility, and social stigma; encouraging them and helping them to meet others with DSD; and sharing the strengths that we can see that they have. We have come far, but have a long way to go.

Algorithm for X-ray Scatter, Beam-Hardening, and Beam Profile Correction in Diagnostic (Kilovoltage) and Treatment (Megavoltage) Cone Beam CT (2008)

Quantitative reconstruction of cone beam X-ray computed tomography (CT) datasets requires accurate modeling of scatter, beam-hardening, beam profile, and detector response. Typically, commercial imaging systems use fast empirical corrections that are designed to reduce visible artifacts due to incomplete modeling of the image formation process. In contrast, Monte Carlo (MC) methods are much more accurate but are relatively slow. Scatter kernel superposition (SKS) methods offer a balance between accuracy and computational practicality. We show how a single SKS algorithm can be employed to correct both kilovoltage (kV) energy (diagnostic) and megavoltage (MV) energy (treatment) X-ray images. Using MC models of kV and MV imaging systems, we map intensities recorded on an amorphous silicon flat panel detector to water-equivalent thicknesses (WETs). Scattergrams are derived from acquired projection images using scatter kernels indexed by the local WET values and are then iteratively refined using a scatter magnitude bounding scheme that allows the algorithm to accommodate the very high scatter-to-primary ratios encountered in kV imaging. The algorithm recovers radiological thicknesses to within 9% of the true value at both kV and megavolt energies. Nonuniformity in CT reconstructions of homogeneous phantoms is reduced by an average of 76% over a wide range of beam energies and phantom geometries.
Myosin VI: a multifunctional motor (2004)

Myosin VI moves towards the minus end of actin filaments unlike all the other myosins so far studied, suggesting that it has unique properties and functions. Myosin VI is present in clathrin-coated pits and vesicles, in membrane ruffles and in the Golgi complex, indicating that it has a wide variety of functions in the cell. To investigate the cellular roles of myosin VI, we have identified a variety of myosin VI-binding partners and characterized their interactions. As an alternative approach, we have studied the in vitro properties of intact myosin VI. Previous studies assumed that myosin VI existed as a dimer but our biochemical characterization and electron microscopy studies reveal that myosin VI is a monomer. Using an optical tweezers force transducer, we showed that monomeric myosin VI is a non-processive motor with a large working stroke of 18 nm. Potential roles for myosin VI in cells are discussed.
Motion of nano-objects on polymer brushes (2004)

In this paper we review a new method to move nano-objects on a polymer surface that is made from diblock-copolymer and mixed brushes. Such brush systems consist of polymer chains covalently attached to a surface with high grafting density. If the two polymeric components the brush consists of are incompatible with each other, it shows microphase separation into nanopatterns of well defined size. Such a system possesses the unique property of changing the surface topography in response to different external conditions. Motion of nano objects adsorbed on the brush is induced by having the external conditions and thus the brush topography vary over time. This is shown by studying the distribution of silica nanoparticles adsorbed on several types of brushes while changing the external conditions. We identify parameters required for motion of nano objects, and discuss potential applications of the proposed technique for nano engineering.
REPLACEMENT SENSOR MODEL (RSM) PERFORMANCE FOR TRIANGULATION AND GEOPOSITIONING (2008)

The Replacement Sensor Model (RSM) allows the functionality of many diverse sensor models to be captured in a single generic model. The RSM concept is for the replacement support data to be generated from the original sensor models and their image support data “up-stream” of the user community. Geopositioning performance studies of RSM compare the absolute and relative geolocations and error estimates (accuracy predictions) for objects or “targets” extracted from images using original sensor models with those extracted using RSM with the same image measurements. Triangulation performance studies of RSM compare the absolute and relative geolocations and error estimates of tie points that participate in triangulations. In these studies, two triangulations are performed – one based on the original sensor models and their image support data, and another based on the RSM sensor models and their image support data. The most recent RSM triangulation and geopositioning performance results are presented in this paper, incorporating the latest enhancements in RSM adjustability and error modeling. The results show that the RSM performance is virtually equivalent to the original sensor model performance.
Controlling Two-Dimensional Tethered Vesicle Motion Using an Electric Field:  Interplay of Electrophoresis and Electro-Osmosis (2006)

We recently introduced methods to tether phospholipid vesicles or proteoliposomes onto a fluid-supported lipid bilayer using DNA hybridization (Yoshina-Ishii, C.; Miller, G. P.; Kraft, M. L.; Kool, E. T.; Boxer, S. G. J. Am. Chem. Soc. 2005, 127, 1356-1357). These intact tethered vesicles diffuse in two dimensions parallel to the supporting membrane surface. In this article, we report the dynamic response of individual tethered vesicles to an electric field applied parallel to the bilayer surface. Vesicles respond to the field by moving in the direction of electro-osmotic flow, and this can be used to reversibly concentrate tethered vesicles against a barrier. By adding increasing amounts of negatively charged phosphatidylserine to the supporting bilayer to increase electro-osmosis, the electrophoretic mobility of the tethered vesicles can be increased. The electro-osmotic contribution can be modeled well by a sphere connected to a cylindrical anchor in a viscous membrane with charged headgroups. The electrophoretic force on the negatively charged tethered vesicles opposes the electro-osmotic force. By increasing the amount of negative charge on the tethered vesicle, drift in the direction of electro-osmotic flow can be slowed; at high negative charge on the tethered vesicle, motion can be forced in the direction of electrophoresis. The balance between these forces can be visualized on a patterned supporting bilayer containing negatively charged lipids that reorganize in an externally applied electric field to create a gradient of charge within a corralled region. The charge gradient at the surface creates a gradient of electro-osmotic flow, and vesicles carrying similar amounts of negative charge can be focused to a region perpendicular to the applied field where electrophoresis is balanced by electro-osmosis, away from the corral boundary. Electric fields are effective tools to direct tethered vesicles and concentrate them and to measure the tethered vesicle's electrostatic properties.
Current Sources For Impedance Imaging Systems (2005)

It can be seen from the calculations in (l) that impedance imaging systems that apply currents and measure voltages are less sensitive to errors than systems which apply voltages and measure currents. For some system designs (2), it is possible to use a single floating current source with an appropriate switching system to sequentially address all electrodes in pairs. Other system designs require an individual source for each electrode, with consequent increased costs (3). For in-vivo systems which operate above 10 kHz, high resolution images require a high internal impedance for the current sources in the presence of cables from the instrument to the electrodes. This paper explores some of the circuits available for such current sources, and indicates their disadvantages along with an approach to a circuit configuration that resolves most of the problems.

Here we report structure-activity relationship study of a novel hybrid series of compounds where structural alteration of aromatic hydrophobic moieties connected to the piperazine ring and bioisosteric replacement of the aromatic tetralin moieties were carried out. Binding assays were carried out with HEK-293 cells expressing either D2 or D3 receptors with tritiated spiperone to evaluate inhibition constants (K(i)). Functional activity of selected compounds in stimulating GTPgammaS binding was assessed with CHO cells expressing human D2 receptors and AtT-20 cells expressing human D3 receptors. SAR results identified compound (-)-24c (D-301) as one of the lead molecules with preferential agonist activity for D3 receptor (EC(50) (GTP gamma S); D3 = 0.52 nM; D2/D3 (EC(50)): 223). Compounds (-)-24b and (-)-24c exhibited potent radical scavenging activity. The two lead compounds, (-)-24b and (-)-24c, exhibited high in vivo activity in two Parkinson's disease (PD) animal models, reserpinized rat model and 6-OHDA induced unilaterally lesioned rat model. Future studies will explore potential use of these compounds in the neuroprotective therapy for PD.
Face Recognition Using Support Vector Machines (2003)

Support Vector Machines are a binary classification method and have demonstrated excellent results in pattern recognition. Face recognition is a multi-class problem, where the number of classes is of the known individuals. In this paper we use face data extracted from Eigenfeatures and develope a method to extend SVM to using in multi-class. The training set consists of 5 images of each of the 50 persons equally distributed among frontal, approximately 15°rotated respectively, and the test set consists of 10 images each of the 50 persons. In the ICT-YC face gallery, the proposed system obtains competitive results highly: a correct recognition rate of 94.8% for all the 50 persons, to the less number of the persons and to the famous ORL face gallery we also get good face recognition rate.
