Phenomena of electrical memory effects on the device level and their relations (2008)

Whereas the requirements of communication systems become more stringent, the impacts of memory effects on linearity and efficiency become more noticeable. Memory effects in a communication system arise from several sources. In power amplifier circuits, memory effects are caused by DC supply voltage circuits, matching networks and power devices (transistors). Memory effects of power devices are required to be described accurately by the device model, since these effects can have significant impacts on output power, efficiency and linearity of the circuit. In this paper, different phenomena of device-level memory effects and their relations will be discussed.
Musical neurofeedback for treating depression in elderly people (2015)

We introduce a new neurofeedback approach, which allows users to manipulate expressive parameters in music performances using their emotional state, and we present the results of a pilot clinical experiment applying the approach to alleviate depression in elderly people. Ten adults (9 female and 1 male, mean = 84, SD = 5.8) with normal hearing participated in the neurofeedback study consisting of 10 sessions (2 sessions per week) of 15 min each. EEG data was acquired using the Emotiv EPOC EEG device. In all sessions, subjects were asked to sit in a comfortable chair facing two loudspeakers, to close their eyes, and to avoid moving during the experiment. Participants listened to music pieces preselected according to their music preferences, and were encouraged to increase the loudness and tempo of the pieces, based on their arousal and valence levels. The neurofeedback system was tuned so that increased arousal, computed as beta to alpha activity ratio in the frontal cortex corresponded to increased loudness, and increased valence, computed as relative frontal alpha activity in the right lobe compared to the left lobe, corresponded to increased tempo. Pre and post evaluation of six participants was performed using the BDI depression test, showing an average improvement of 17.2% (1.3) in their BDI scores at the end of the study. In addition, an analysis of the collected EEG data of the participants showed a significant decrease of relative alpha activity in their left frontal lobe (p = 0.00008), which may be interpreted as an improvement of their depression condition.
Die Konstitution des Palladium(II)‐bromids (1966)

Abstract Palladium(II)‐bromid wurde mit Hilfe von chemischen Transportreaktionen in Form schwarzbrauner Einkristalle dargestellt. Röntgenographische Untersuchungen unter Verwendung von F OURIER ‐Methoden führten zu folgendem Strukturmodell: Die Palladiumatome sind verzerrt quadratisch von vier Bromatomen umgeben. Jedes Bromatom besitzt zwei Palladium‐Nachbarn (Pd I Br: 2,34; Pd II Br: 2,57 äR). Die Koordinationsquadrate sind zu gewellten Kette verknüpft. Entsprechend der Elektronenkonfiguration des Pd ++ mit 4 d 8 ist die Verbindung diamagnetisch.
Influence of Chloride-Ion Adsorption Agent on Chloride Ions in Concrete and Mortar (2014)

The influence of a chloride-ion adsorption agent (Cl agent in short), composed of zeolite, calcium aluminate hydrate and calcium nitrite, on the ingress of chloride ions into concrete and mortar has been experimentally studied. The permeability of concrete was measured, and the chloride ion content in mortar was tested. The experimental results reveal that the Cl agent could adsorb chloride ions effectively, which had penetrated into concrete and mortar. When the Cl agent was used at a dosage of 6% by mass of cementitious materials in mortar, the resistance to the penetration of chloride ions could be improved greatly, which was more pronounced when a combination of the Cl agent and fly ash or slag was employed. Such an effect is not the result of the low permeability of the mortar, but might be a result of the interaction between the Cl agent and the chloride ions penetrated into the mortar. There are two possible mechanisms for the interaction between the Cl agent and chloride ion ingress. One is the reaction between calcium aluminate hydrate in the Cl agent and chloride ions to form Friedel's salt, and the other one is that calcium aluminate hydrate reacts with calcium nitrite to form AFm during the early-age hydration of mortar and later the NO₂<sup>-</sup> in AFm is replaced by chloride ions, which then penetrate into the mortar, also forming Friedel's salt. More research is needed to confirm the mechanisms.
Outlier Detection Using Random Walks (2006)

The discovery of objects with exceptional behavior is an important challenge from a knowledge discovery standpoint and has attracted much attention recently. In this paper, we present a stochastic graph-based algorithm, called OutRank, for detecting outlying objects. In our method, a matrix is constructed using the similarity between objects and used as the adjacency matrix of the graph representation. The heart of this approach is the Markov model that is built upon this graph, which assigns an outlier score to each object. Using this framework, we show that our algorithm is more powerful than the existing outlier detection schemes and can effectively address the inherent problems of such schemes. Empirical studies conducted on both real and synthetic data sets show that significant improvements in detection rate and a lower false alarm rate are achieved using our proposed framework
Modelling the frontal lobes in health and disease (1999)

A simplified model of the architecture of the frontal lobes, the ACTION network, is applied to study the task of temporal sequence storage and generation. In particular we analyse the manner in which a hard-wired model of such storage is affected by damage corresponding to loss of dopamine. We find support for the DeLong model of 1990, in which the subthalamic nucleus in the indirect path plays an important role.

THE EFFECTIVENESS OF GROUP COUNSELING BASED ON A COGNITIVE-BEHAVIORAL APPROACH IN MODIFYING STUDENTS’ ATTACHMENT STYLES (2011)

he purpose of this study was to investigate the effectiveness of group counseling based on a cognitive-behavioral approach in modifying students' attachment styles. The sample consisted of 60 high school girls who were selected by multistage sampling. The participants completed the Revised Adult Attachment Scale (RAAS; Collins and Reed, 1996). The research design was pretest-post test control group with following-up phase. The experimental group received 10 sessions of cognitive-behavioral group counseling (90 minutes per session). Data were analyzed using covariance analysis, paired t-test, and Friedman test. The results indicated the effectiveness of group counseling based on cognitive-behavioral approach in modifying attachment styles of students. The follow-up results indicated that the effect of the intervention was effective after 45
Hardness of Learning Halfspaces with Noise (2009)

Learning an unknown halfspace (also called a perceptron) from labeled examples is one of the classic problems in machine learning. In the noise-free case, when a halfspace consistent with all the training examples exists, the problem can be solved in polynomial time using linear programming. However, under the promise that a halfspace consistent with a fraction $(1-\varepsilon)$ of the examples exists (for some small constant $\varepsilon>0$), it was not known how to efficiently find a halfspace that is correct on even 51% of the examples. Nor was a hardness result that ruled out getting agreement on more than 99.9% of the examples known. In this work, we close this gap in our understanding and prove that even a tiny amount of worst-case noise makes the problem of learning halfspaces intractable in a strong sense. Specifically, for arbitrary $\epsilon,\delta > 0$, we prove that given a set of examples-label pairs from the hypercube, a fraction $(1-\varepsilon)$ of which can be explained by a halfspace, it is NP-hard to find a halfspace that correctly labels a fraction $(1/2+\delta)$ of the examples. The hardness result is tight since it is trivial to get agreement on $1/2$ the examples. In learning theory parlance, we prove that weak proper agnostic learning of halfspaces is hard. This settles a question that was raised by Blum et al., in their work on learning halfspaces in the presence of random classification noise [Algorithmica, 22 (1998), pp. 35–52], and raised by authors of some more recent works as well. Along the way, we also obtain a strong hardness result for another basic computational problem: solving a linear system over the rationals.
High precision U-PB geochronology and implications for the tectonic evolution of the Superior Province (1986)

The underlying mechanisms of Archean tectonics and the degree to which modern plate tectonic models are applicable early in Earth's history continue to be a subject of considerable debate. A precise knowledge of the timing of geological events is of the utmost importance in studying this problem. The high precision U-Pb method has been applied in recent years to rock units in many areas of the Superior Province. Most of these data have precisions of about + or - 2-3 Ma. The resulting detailed chronologies of local igneous development and the regional age relationships furnish tight constraints on any Archean tectonic model. Superior province terrains can be classified into 3 types: (1) low grade areas dominated by meta-volcanic rocks (greenstone belts); (2) high grade, largely metaplutonic areas with abundant orthogneiss and foliated to massive I-type granitoid bodies; and (3) high grade areas with abundant metasediments, paragneiss and S-type plutons. Most of the U-Pb age determinations have been done on type 1 terrains with very few having been done in type 3 terrains. A compilation of over 120 ages indicates that the major part of igneous activity took place in the period 2760-2670 Ma, known as the Kenoran event. This event was ubiquitous throughout the Superior Province.
Electronic structure and bandgap engineering of CdTe nanotubes and designing the CdTe nanotube–fullerene hybrid nanostructures for photovoltaic applications (2014)

The electronic structure of CdTe nanotube–fullerene nanocomposites has been explored. Within this context, the structural and electronic properties of isolated 100 faceted CdTe nanotubes (NTs) with hexagonal cross-sections were first investigated using the self-consistent-charge density-functional tight-binding (SCC-DFTB) method. The possibility of band gap engineering of clean CdTe nanotubes is explored by varying either the size or wall thickness of the NTs. However, the efficient modification of the band gap can be attained by introducing the molecular states of fullerene into the band gap region of the CdTe NTs. The effects of the modulation of the band alignment through the variation in the wall thickness of the CdTe NTs on the electron injection rate from the NT to C60 in hybrid systems have been explored and we also found that the light harvesting efficiency of these nanohybrids can be maximized by increasing the concentration of the C60–thiol moieties. The position of the electronic energy levels offers information about the electronic structure of the hybrid systems such as whether it constructs type I or type II hetero-junctions, which bears key information for their application in photovoltaics. We also studied the electronic structure of CdTe–fullerene hybrid nanostructures with a series of fullerenes of different compositions.
Light Backscatter Sensor Applications in Milk Coagulation (2007)

Complete automation of cheese production requires an inline method for monitoring milk coagulation. Static light backscatter measurements have been demonstrated to be one of the most effective techniques for this purpose. This study reviewed the most significant implications of recent research findings on the use of light backscatter for monitoring milk coagulation.
Labdane Diterpenes of <i>Leonurus </i><i>s</i><i>ibiricus</i> (2004)

Seven new labdane diterpenes, sibiricinones A-E (1-4, 6) and 15-epi-sibiricinones D and E (5 and 7), and the flavone genkwanin were isolated from the aerial parts of Leonurus sibiricus. Sibiricinone D (4) and 15-epi-sibiricinone D (5), and sibiricinone E (6) and 15-epi-sibiricinone E (7), respectively, were isolated as C-15 epimeric pairs. These secondary metabolites were identified on the basis of 1D and 2D NMR including (1)H-(1)H COSY, HSQC, and HMBC spectroscopic techniques. The stereochemical configurations of compounds 4-7 were assigned through 2D T-ROESY and selective NOE experiments.
Temporal Sequence of Plaque Formation in the Cerebral Cortex of Non-Demented Individuals (1993)

One of the hallmarks of Alzheimer's disease is the presence of argyrophilic plaques (arg-P) accompanying dementia and other forms of cognitive alterations. In the present investigation 195 non-demented, cognitively normal patients were grouped according to the presence or absence of critical coronary artery disease (cCAD), defined as a 75% or greater stenosis of one of the epicardial arteries. None of the subjects had significant cerebral vascular disease. The parahippocampal gyrus (PHG) and frontal pole were analyzed for the presence of arg-P, A4 deposition, ALZ-50 immunoreactive (IR) neurons and neuropil threads (NT). Individuals with cCAD have a significantly greater incidence of plaques than non-heart disease (non-HD) subjects. Every cCAD subject had ALZ-50 IR neurons in the PHG and a greater incidence of NT as compared to the non-HD subjects. Every subject with plaques also had IR neurons and NT in the PHG. Based on the presumption that early neurodegeneration labeled by ALZ-50 antibody and amyloid deposition are in some way linked, then the sequence of plaque formation is initiated by the presence of ALZ-50 IR neurons followed in order by NT, A4 deposition and diffuse form arg-P.
Improving Annotation for 3D Pose Dataset of Fine-Grained Object Categories (2018)

Existing 3D pose datasets of object categories are limited to generic object types and lack of fine-grained information. In this work, we introduce a new large-scale dataset that consists of 409 fine-grained categories and 31,881 images with accurate 3D pose annotation. Specifically, we augment three existing fine-grained object recognition datasets (StanfordCars, CompCars and FGVC-Aircraft) by finding a specific 3D model for each sub-category from ShapeNet and manually annotating each 2D image by adjusting a full set of 7 continuous perspective parameters. Since the fine-grained shapes allow 3D models to better fit the images, we further improve the annotation quality by initializing from the human annotation and conducting local search of the pose parameters with the objective of maximizing the IoUs between the projected mask and the segmentation reference estimated from state-of-the-art deep Convolutional Neural Networks (CNNs). We provide full statistics of the annotations with qualitative and quantitative comparisons suggesting that our dataset can be a complementary source for studying 3D pose estimation. The dataset can be downloaded at http://users.umiacs.umd.edu/~wym/3dpose.html.
Experimental Therapeutic Strategies in Epilepsies Using Anti-Seizure Medications (2021)

Epilepsies are among the most common neurological problems. The disease burden in patients with epilepsy is significantly high, and epilepsy has a huge negative impact on patients' quality of life with epilepsy and their families. Anti-seizure medications are the mainstay treatment in patients with epilepsy, and around 70% of patients will ultimately control with a combination of at least two appropriately selected anti-seizure medications. However, in one-third of patients, seizures are resistant to drugs, and other measures will be needed. The primary goal in using experimental therapeutic medication strategies in patients with epilepsy is to prevent recurrent seizures and reduce the rate of traumatic events that may occur during seizures. So far, various treatments using medications have been offered for patients with epilepsies, which have been classified according to the type of epilepsy, the effectiveness of the medications, and the adverse effects. Medications such as Levetiracetam, valproic acid, and lamotrigine are at the forefront of these patients' treatment. Epilepsy surgery, neuro-stimulation, and the ketogenic diet are the main measures in patients with medication-resistant epilepsies. In this paper, we will review the therapeutic approach using anti-seizure medications in patients with epilepsy. However, it should be noted that some of these patients still do not respond to existing treatments; therefore, the limited ability of current therapies has fueled research efforts for the development of novel treatment strategies. Thus, it seems that in addition to surgical measures, we should look for more specific agents that have less adverse events and have a greater effect in stopping seizures.
Techniques for automatic on chip closed loop transfer function monitoring for embedded charge pump phase locked loops (2003)

Charge Pump Phase locked loops are used in a variety of applications, including on chip clock synthesis, symbol timing recovery for serial data streams, and generation of frequency agile high frequency carrier signals. In many applications PLLs are embedded into larger digital systems, in consequence, analogue test access is often limited. Test motivation is thus towards methods that can either aid digital only test of the PLL, or alternatively facilitate complete self testing of the PLL. One useful characterisation technique used by PLL designers is that of closed loop phase transfer function measurement. This test allows, an estimation of the PLL's natural frequency, damping, and 3 dB bandwidth to be made from the magnitude and phase response plots. These parameters relate directly to the time domain response of the PLL and will indicate errors in the PLL circuitry. This paper provides suggestions towards test methods that use a novel maximum frequency detection technique to aid automatic measurement of the closed loop phase transfer function. In addition, techniques presented have potential for full BIST applications.

Scaling of neuron number and volume of the pulvinar complex in new world primates: Comparisons with humans, other primates, and mammals (2007)

The lateral posterior nucleus and pulvinar (LP-pulvinar complex) are the principal thalamic nuclei associated with the elaborate development of the dorsal and ventral streams of the parietal cortex in primates. In humans, a novel site of origin for a subpopulation of pulvinar neurons has been observed, the ganglionic eminence of the telencephalon. This additional site of neuron origin has been proposed to contribute to the pulvinar's evolutionary expansion (Letinic and Rakic [2001] Nat Neurosci 4:930-936). Studies of neuron number in the LP-pulvinar complex in gibbon, chimpanzee, and gorilla compared to humans, however, did not show that the human LP-pulvinar was unexpectedly large (Armstrong [1981] Am J Phys Anthropol 55:369-383). Here we enlarge the allometric basis for comparison by determining neuron number in the LP-pulvinar complex of six New World primates (Cebus apella, Saimiri ustius, Saguinus midas niger, Alouatta caraya, Aotus azarae, and Callicebus moloch) as well as measuring LP-pulvinar volume in a further set of 24 species including additional primates, carnivores, and rodents. The volume of the LP-pulvinar complex scaled with positive allometry with respect to brain volume across all species examined. The scaling of the number of neurons in the LP-pulvinar complex was extremely similar in New World primates and anthropoid apes, with the human LP-pulvinar value close to the regression line. Comparison of the relative volumes of the LP-pulvinar in the larger sample confirmed this observation, and further demonstrated that both primates and carnivores showed a "grade shift" in its size compared to rodents, with the pulvinar comprising a greater proportion of total brain volume across the board. Diurnal, nocturnal, or crepuscular niche did not discriminate LP-pulvinar size across taxa.
Infectivity experiments with <i>Cyprinus carpio</i> iridovirus (CCIV), a virus unassociated with carp gill necrosis (1990)

Abstract. Experiments to determine Cyprinus carpio iridovirus (CC1V) virulence to fish of different ages and species were performed; viz. carp, Cyprinus carpio L., goldfish, Carassius auratus (L.), and rainbow trout, Oncorhynchus mykiss (Walbaum). Neither signs of disease nor mortality occurred in any of the fish species tested. Five passages of the virus in carp resulted in its loss and, not surprisingly, there was no enhancement of virulence. In carp inoculated intraperitoncally, the virus persisted for more than 6 weeks at 18‐20°C, more than 12 weeks at a water temperature increasing from 10 to 20°C and more than 27 weeks at 6 5‐8°C. The fish cleared itself of the virus after more than 6 weeks maintenance at 18‐20°C. The viral infectivity via water is very low. It was impossible to infect the fish with the cell culture grown virus either by water immersion or by prolonged cohabitation with experimentally infected fish. From infectivity data, the authors conclude that the investigated iridovirus is not the aetiological agent of carp gill necrosis.
