Phase shifts with complementary temperature coefficients (TCs) are generated by using PPFs made from different resistor types (p-poly and silicided p-poly). The phase shift of each filter is determined by a zero-crossing (ZC) detector and then digitized by a digital phase-domain <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\Delta \Sigma $ </tex-math></inline-formula> modulator ( <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\Phi $ </tex-math></inline-formula> - <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\Delta \Sigma \text{M}$ </tex-math></inline-formula> ). The results are then combined in the digital domain via fixed polynomials to produce a temperature-independent phase shift.

Phonons, phasons, and dislocations in quasicrystals (1986)

In this paper we examine the detailed relationship between the density-wave and unit-cell descriptions of quasicrystals. We show that phonons, phasons, and dislocations correspond to translations, distortions, and rearrangements of unit cells. The associated density-wave images closely resemble experimental electron micrographs of the icosahedral phase of aluminum-manganese and related alloys. Partial dislocations are also discussed and a natural classification scheme for partials is proposed.

On MBR Approximation of Histories for Historical Queries: Expectations and Limitations (2007)

Traditional approaches for efficiently processing historical queries, where a history is a multidimensional time-series, employ a two step filter-and-refine scheme. In the filter step, an approximation of each history often as a set of minimum bounding hyper-rectangles (MBRs) is organized using a spatial index structure such as R-tree. The index is used to prune redundant disk accesses and to reduce the number of pairwise comparisons required in the refine step. To improve the efficiency of the filtering step, a heuristic is used to decrease the expected number of MBRs that overlap with a query, by reducing the volume of empty space indexed by the index. The heuristic selects, among all possible splitting schemes of a history, the one which results to a set of MBRs with minimum total volume. Although this heuristic is expected to improve the performance of spatial and history based queries with small temporal and spatial extents, in many real settings, the performance of historical queries depends on the extent of the query. Moreover, the optimal approximation of a history is not always the one with minimum total volume. In this paper, we present the limitations of using volume as a criteria for approximating histories, specially in high dimensional cases, where it is not feasible to index MBRs by traditional spatial index structures.
SpeckleSense (2011)

Motion sensing is of fundamental importance for user interfaces and input devices. In applications, where optical sensing is preferred, traditional camera-based approaches can be prohibitive due to limited resolution, low frame rates and the required computational power for image processing. We introduce a novel set of motion-sensing configurations based on laser speckle sensing that are particularly suitable for human-computer interaction. The underlying principles allow these configurations to be fast, precise, extremely compact and low cost. We provide an overview and design guidelines for laser speckle sensing for user interaction and introduce four general speckle projector/sensor configurations. We describe a set of prototypes and applications that demonstrate the versatility of our laser speckle sensing techniques.
Visualization for Relevance Assessments (2014)

Visual data exploration is a well-known technique in the data mining toolbox for analyzing and understanding large amounts of data. In information retrieval, visualization is still perceived as a front-end or user facing feature while, at the same time, it can be very effective in the back-end for data analysis. Currently, the research community does not sufficiently analyze the reasons underlying the assessments they use for evaluation, which may lead to bias or error when reporting system performance. In this paper we examine the integration of information visualization techniques for visually exploring and analyzing relevance assessments. We argue that visual tools should be integrated as a core component of the infrastructure for relevance assessment and evaluation.

Styling and Reflector Design - New Reflector Shapes for Low Beam, High Beam and Foglamps (1997)

&lt;div class="htmlview paragraph"&gt;For the automotive industry, the styling of a car is an important feature. Since the appearance of a car is strongly characterized by the headlamp, stylistic aspects have an increasing influence on the development of headlamps. At the same time, the trend goes toward reducing the constructional volume available to the headlamp and also integrating other functions such as foglamps. To fulfill all these requirements, new reflector shapes had to be created.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;In this paper, different reflector concepts for low beam, high beam and foglamps are presented. They will be discussed under consideration of stylistic aspects (e.g. space for the required bulb shield, semi-clear outer lens) and technical aspects (e.g. thermal stress of plastic lenses).&lt;/div&gt;
Cool Interconnect: A 1024-bit Wide Bus for Chip-to-Chip Communications in 3-D Integrated Circuits (2018)

In this paper, we present “Cool Interconnect,” a 1024-bit wide bus that we have developed to provide a standardized method of interconnecting chips in 3-D integrated circuits (3DICs). This wide bus chip-to-chip interconnect can be used to realize low-power high-performance multicore systems to meet the increasing demand for advanced electronics to enable autonomous vehicles and Internet of Things devices. The bus has been implemented using a <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$40\times 40$ </tex-math></inline-formula> fine-pitch array of through-silicon vias and bump joints. In addition, we have developed a testing methodology based on the boundary scan method to confirm the electrical performance of wide bus chip-to-chip interconnect in 3DICs. Cool Interconnect test chips were designed, fabricated, and flip-chip stacked. Joint Test Action Group (JTAG) and electrical connection tests were used to confirm the successful operation of the test chips, including the chip-to-chip interconnect.
The Certicom Challenges ECC2-X (2009)

Abstract. To encourage research on the hardness of the elliptic-curve discrete-logarithm problem (ECDLP) Certicom has published a series of challenge curves and DLPs. This paper analyzes the costs of breaking the Certicom challenges over the binary fields F 2 131 and F 2 163 on a variety of platforms. We describe details of the choice of step function and distinguished points for the Koblitz and non-Koblitz curves. In contrast to the implementations for the previous Certicom challenges we do not restrict ourselves to software and conventional PCs, but branch out to cover the majority of available platforms such as various ASICs, FPGAs, CPUs and the Cell Broadband Engine. For the field arithmetic we investigate polynomial and normal basis arithmetic for these specific fields; in particular for the challenges
Short interfering RNA‐induced gene silencing is transmitted between cells from the mammalian central nervous system (2006)

Although short interfering RNA (siRNA)-induced gene silencing can be transmitted between cells in plants and in Caenorhabditis elegans, this phenomenon has been barely studied in mammalian cells. Both immortalized oligodendrocytes and SNB19 glioblastoma cells were transfected with siRNA constructs for phosphatase and tensin homolog deleted on chromosome 10 (PTEN) or Akt/protein kinase B (Akt). Co-cultures were established between silenced cells and non-silenced cells which were hygromycin resistant and/or expressed green fluorescent protein. After fluorescence sorting or hygromycin selection to remove the silenced cells, the expression of PTEN or Akt genes in the originally unsilenced cells was in all cases significantly decreased. Importantly, silencing did not occur in transwell culture studies, suggesting that transmission of the silencing signal requires a close association between cells. These results provide the first direct demonstration that an siRNA-induced silencing signal can be transmitted between mammalian CNS cells.
Using a Debye polarization cell to predict double-layer capacitor performance (2003)

Double-layer capacitors (DLCs) are relatively complex devices. Different models have been proposed for DLCs. Presented in this paper is an evaluation of the Debye Polarization cell as a model for a double-layer capacitor. The elements in this circuit model can be related to the chemical reactions which occur inside the DLC. Circuit element values are found from AC impedance measurements for a DLC and a computer program which utilizes a nonlinear least squares fitting technique. Variations in circuit element values with DC bias level and manufacturing have been investigated. The performance of the Debye polarization cell in slow discharge and pulse load applications has been compared to actual circuit measurements and to simulated results using a classical equivalent circuit.

Minimally invasive approaches to aneurysms of the anterior circulation: selection criteria and clinical outcomes (2018)

Over the last few decades, cerebrovascular surgery has gravitated towards a minimally invasive philosophy without compromising the foundational principles of patient safety and surgical efficacy. Enhanced radiosurveillance modalities and increased average life expectancy have resulted in an increased reported incidence of intracranial aneurysms. Although endovascular therapies have gained popularity in the recent years, microsurgical clipping continues to be of value in the management of these aneurysms owing to its superior occlusion rates, applicability to complex aneurysms and reduced retreatment rates. The concept of keyhole transcranial procedures has advanced the field significantly leading to decreased postoperative neurological morbidity and quicker recovery. The main keyhole neurosurgical approaches include the supraorbital craniotomy (SOC), lateral supraorbital craniotomy (LSOC), mini-pterional craniotomy (MPTC), mini-orbitozygomatic craniotomy and the mini anterior interhemispheric approach (MAIA). As these minimally invasive approaches can have an inherent limitation of a narrow viewing angle and low regional illumination, the use of endoscopic assistance in such procedures is being popularized. Neuroendoscopy can aid in the visualization of hidden neurovascular structures and inspection of the parent arterial segment without undue retraction of the lesion. This review focuses on the historical progression of the surgical management of intracranial aneurysms, the technical details of various minimally invasive approaches, patient selection and clinical outcomes of the anterior circulation aneurysms and useful tenets to avoid complications during these procedures. Meticulous preoperative planning to understand the patient's vascular anatomy, the orientation and relationship of the aneurysm to adjacent structures, use of neuronavigation guidance and endoscopic assistance if needed can lead to an optimal surgical outcome while minimizing neurological morbidity and mortality.
Application of Optimal Interpolation to Spatially and Temporally Sparse Observations of Aerosol Optical Depth (2022)

Aerosol optical depth (AOD) is one of the basic characteristics of atmospheric aerosol. A global ground-based network of sun and sky photometers, the Aerosol Robotic Network (AERONET) provides AOD data with low uncertainty. However, AERONET observations are sparse in space and time. To improve data density, we merged AERONET observations with a GEOS-Chem chemical transport model prediction using an optimal interpolation (OI) method. According to OI, we estimated AOD as a linear combination of observational data and a model forecast, with weighting coefficients chosen to minimize a mean-square error in the calculation, assuming a negligible error of AERONET AOD observations. To obtain weight coefficients, we used correlations between model errors in different grid points. In contrast with classical OI, where only spatial correlations are considered, we developed the spatial-temporal optimal interpolation (STOI) technique for atmospheric applications with the use of spatial and temporal correlation functions. Using STOI, we obtained estimates of the daily mean AOD distribution over Europe. To validate the results, we compared daily mean AOD estimated by STOI with independent AERONET observations for two months and three sites. Compared with the GEOS-Chem model results, the averaged reduction of the root-mean-square error of the AOD estimate based on the STOI method is about 25%. The study shows that STOI provides a significant improvement in AOD estimates.
Measurement ofBc+Production in Proton-Proton Collisions ats=8  TeV (2015)

Production of Bc+ mesons in proton-proton collisions at a center-of-mass energy of 8 TeV is studied with data corresponding to an integrated luminosity of 2.0 fb-1 recorded by the LHCb experiment. The ratio of production cross sections times branching fractions between the Bc+→J/ψπ+ and B+→J/ψK+ decays is measured as a function of transverse momentum and rapidity in the regions 0<pT<20 GeV/c and 2.0<y<4.5. The ratio in this kinematic range is measured to be (0.683±0.018±0.009)%, where the first uncertainty is statistical and the second systematic.
Ex vivo target engagement of the Abeta oligomer disassembling compound RD2 in patient derived brain homogenates (2022)

Abstract Background Soluble Aβ oligomers are highly toxic and may be responsible for development and progression of Alzheimer’s disease (AD). Elimination of Aβ oligomers is therefore a promising therapeutic strategy. The compound RD2 was developed to stabilize Aβ monomers in their native conformation, which is very close to an intrinsically disordered protein (IDP). RD2 has demonstrated already to directly eliminate soluble Aβ oligomers in vitro and in vivo and to improve cognition or decelerate neurodegeneration in four different animal models in four different laboratories 1,2 . Here, we wanted to test if RD2 is able to disassemble Aβ oligomers obtained from AD patient derived brain tissue. Method Aβ oligomers in AD patient derived brain tissue homogenates were incubated with different concentrations of RD2 and control compounds. Aβ oligomer concentrations were determined longitudinally by the sFIDA assay, a single‐particle sensitive method for quantitating protein oligomers and aggregates. Result RD2 concentration and incubation time‐dependent reduction of Aβ oligomers in brain homogenates was observed. Control compounds did not reduce Aβ oligomer concentrations. Conclusion The incubation time and RD2 concentration dependent disassembly of Aβ oligomers from human brain homogenate suggest a very efficient ability of RD2 to fulfill its mode of action, namely the direct disassembly of Aβ oligomers into their Aβ monomer building blocks. Kinetic analysis and the mode of action resemble very much that of catalytic chaperones.
Architectural Complexity Measures of Recurrent Neural Networks (2016)

In this paper, we systematically analyze the connecting architectures of recurrent neural networks (RNNs). Our main contribution is twofold: first, we present a rigorous graph-theoretic framework describing the connecting architectures of RNNs in general. Second, we propose three architecture complexity measures of RNNs: (a) the recurrent depth, which captures the RNN's over-time nonlinear complexity, (b) the feedforward depth, which captures the local input-output nonlinearity (similar to the "depth" in feedforward neural networks (FNNs)), and (c) the recurrent skip coefficient which captures how rapidly the information propagates over time. We rigorously prove each measure's existence and computability. Our experimental results show that RNNs might benefit from larger recurrent depth and feedforward depth. We further demonstrate that increasing recurrent skip coefficient offers performance boosts on long term dependency problems.

Monolayer Graphene-Directed Growth and Neuronal Differentiation of Mesenchymal Stem Cells (2015)

The development of an efficient platform for the growth and neuronal differentiation of stem cells is crucial for autologous cell therapy and tissue engineering to treat various neuronal disorders and neurodegenerative diseases. In this study, we describe the use of highly uniform graphene platforms that provide unique environments where unusual three-dimensional spheroids of human mesenchymal stem cells (hMSCs) are formed, which is advantageous for the differentiation of hMSCs into neurons. We suppose that graphene regulates the interactions at cell-substrate or cell-cell interfaces, consequently promoting the neurogenesis of hMSCs as well as the outgrowth of neurites, which was evidenced by the graphene-induced upregulation of early neurogenesis-related genes. We also demonstrated that the differentiated neurons from hMSCs on graphene are notably sensitive to external ion stimulation, and their neuronal properties can be maintained even after detaching and re-seeding onto a normal cell culture substrate, suggesting the enhanced maturity of resulting neuronal cells. Thus, we conclude that monolayer graphene is capable of regulating the growth and neural differentiation of hMSCs, which would provide new insight and strategy not only for autologous stem cell therapy but for tissue engineering and regenerative medicine based on graphene scaffolds.
