Design and fabrication of superhydrophobic cellulose nanocrystal films by combination of self-assembly and organocatalysis (2023)

Cellulose nanocrystals, which have unique properties of high aspect ratio, high surface area, high mechanical strength, and a liquid crystalline nature, constitute a renewable nanomaterial with great potential for several uses (e.g., composites, films and barriers). However, their intrinsic hydrophilicity results in materials that are moisture sensitive and exhibit poor water stability. This limits their use and competitiveness as a sustainable alternative against fossil-based materials/plastics in packaging, food storage, construction and materials application, which cause contamination in our oceans and environment. To make cellulose nanocrystal films superhydrophobic, toxic chemicals such as fluorocarbons are typically attached to their surfaces. Hence, there is a pressing need for environmentally friendly alternatives for their modification and acquiring this important surface property. Herein, we describe the novel creation of superhydrophobic, fluorocarbon-free and transparent cellulose nanocrystal films with functional groups by a bioinspired combination of self-assembly and organocatalytic surface modification at the nanoscale using food approved organic acid catalysts. The resulting film-surface is superhydrophobic (water contact angle > 150°) and has self-cleaning properties (the lotus effect). In addition, the superhydrophobic cellulose nanocrystal films have excellent water stability and significantly decreased oxygen permeability at high relative humidity with oxygen transmission rates better than those of commonly used plastics.

Born in 1938, she died peacefully at her home on January 20, 2023. Sandra was a trailblazer. Her research focusing on auditory pattern perception in infancy and early childhood single-handedly started developmental research in music perception and cognition. Her experimental studies documented that infants have basic skills that form the building blocks for remembering and responding emotionally to music, including the capability to perceive and categorize auditory sequences on the basis of pitch, upward or downward changes in pitch, and rhythm. Her research also established that singing to infants is a universal behavior, which ultimately facilitates language acquisition and bonding with caregivers.

Acoustic broadband communications over deep drill strings using adaptive OFDM (2013)

In this paper, we report first acoustic communications experiments along deep drill strings enabling data rates up to 20 kbit/s. To reduce costs for geothermal energy, search for water-bearing fault zones in the rocks hundreds of meters below the ground will be assisted by seismic prediction while drilling (SPWD) enabling control of the drilling direction. The SPWD tool needs higher data rates to the ground. In contrast to common mud-pulse telemetry offering few bit/s, our approach is based on acoustic wave propagation along the steel wall of the drill string. Based on waveguide theory, we develop a tractable channel model for drill-string communication predicting the pass and stopbands created by regular screw joints between the pipes. For data transmission, we use closed-loop adaptive orthogonal frequency division multiplexing (OFDM) following the 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE). First results indicate that, in this way, much higher data rates can be realized in future deep drilling applications.
Microfabricated High-Speed Axial-Flux Multiwatt Permanent-Magnet Generators—Part I: Modeling (2006)

This paper presents the modeling of permanent-magnet (PM) generators for use in microscale power generation systems. The generators are three-phase, axial-flux, synchronous machines, each consisting of a multipole, surface-wound stator and PM rotor. The machines are modeled by analytically solving two-dimensional (2-D) magneto-quasi-static Maxwell's equations as a function of radius. The 2-D field solutions are then integrated over the radial span of the machine to determine circuit parameters such as open-circuit voltage and inductance as well as hysteresis loss in the stator core and eddy current losses in the stator core and windings. The model provides a computationally fast method to determine power and efficiency of an axial-flux PM machine as a function of geometry, speed, and material properties. The open-circuit voltage predictions are also shown to agree well with 3-D finite-element analysis simulation results. 1700
Perceived fatigue among aging drivers : an examination of the impact of age and duration of driving time on a simulator (2015)

Aging population is a worldwide phenomenon and in the next forty years, it will increase importantly. Older drivers are more at risk of injuries and deaths than other groups of drivers (e.g., Brorsson, 1989 ; Cotrell & Wild, 1999 ; Gresset & Meyer, 1994 ; Stutts, Wilkins & Vaughn, 2004). Fatigue has been identified as a leading cause of accidents among that group of drivers (Clarke, Ward, Bartle, & Truman, 2010). The aims of this study is to verify if perceived fatigue among two groups of older drivers varies according to their age group and if perceived fatigue increases in a 45 minutes driving experience in a driving simulator. Method: Participants were 25 drivers 55 years and older, who were asked to drive on a monotonous road in a simulator for about 40 to 50 minutes. Monotonous roads are well-known to cause fatigue (Thiffault & Bergeron, 2003). Participants were asked to rate their fatigue four times: before starting to drive, after 15, 30 minutes of driving (excluding the 10 minutes for habituation) and once the driving ended, on a scale varying from 0 (not at all) to 10 (very much fatigued). For further analysis, participants were divided in younger aging drivers (55-65 years old; N=13) and older aging drivers (66-75 years old; N=12). Results show that both groups of drivers perceive themselves as getting more tired with driving time and that there were no significant differences between groups. We will discuss these results in light of the importance of future research in the domain and we will conclude with the limits of the study and suggestions for further research.
Carbide‐Derived Carbons: Effect of Pore Size on Hydrogen Uptake and Heat of Adsorption (2006)

Abstract Cryoadsorption is a promising method of enhancing gravimetric and volumetric onboard H 2 storage capacity for future transportation needs. Inexpensive carbide‐derived carbons (CDCs), produced by chlorination of metal carbides, have up to 80 % open‐pore volume with tunable pore size and specific surface area (SSA). Tuning the carbon structure and pore size with high sensitivity by using different starting carbides and chlorination temperatures allows rational design of carbon materials with enhanced C–H 2 interaction and thus increased H 2 storage capacity. A systematic experimental investigation of a large number of CDCs with controlled pore size distributions and SSAs shows how smaller pores increase both the heat of adsorption and the total volume of adsorbed H 2 . It has been demonstrated that increasing the average heat of H 2 adsorption above 6.6 kJ mol –1 substantially enhances H 2 uptake at 1 atm (1 atm = 101 325 Pa) and –196 °C. The heats of adsorption up to 11 kJ mol –1 exceed values reported for metal–organic framework compounds and carbon nanotubes.
Alveolar Rhabdomyosarcoma Presenting as an Acute Orbital Mass in the Medial Rectus Muscle (2007)

Rhabdomyosarcoma is the most common pediatric primary neoplasm in the orbit, often presenting with rapid proptosis and orbital symptoms. We describe a 15-year-old girl who presented with an acute mass in her medial rectus muscle that was subsequently diagnosed as widely disseminated alveolar rhabdomyosarcoma. To our knowledge, this represents the first reported case in which an enlarged extraocular muscle was the initial manifestation of disseminated alveolar rhabdomyosarcoma.
Review on Process-Induced Strain Techniques for Advanced Logic Technologies (2007)

We have extensively studied stress enhancing techniques to increase channel mobility starting at the 130 nm technology node and continued this towards the 45 nm node. Stressed overlayers and spacer materials, strained SOI substrates, embedded SiGe and SiC layers and their proximity effects, the impact of different silicides, stress memorization and compatibility with laser and flash anneals have been investigated. The integration of abovementioned techniques into a CMOS flow resulted in an outstanding pMOS and nMOS performance improvement, no reliability issues and no impact on short channel behavior.
DDIS-15. SYNERGISTIC INHIBITION OF GLIOMA CELL PROLIFERATION BY WITHAFERIN A AND TUMOR TREATING FIELDS (2017)

Glioblastoma (GBM) is the most aggressive and lethal form of primary brain cancer. Standard therapies are non-specific and often of limited effectiveness; thus, efforts are underway to uncover novel, unorthodox therapies against GBM. In previous studies, we investigated Withaferin A, a steroidal lactone from Ayurvedic medicine that inhibits proliferation in cancers including GBM. Another novel approach, tumor treating fields (TTFields), is thought to disrupt mitotic spindle formation and stymie proliferation of actively dividing cells. We hypothesized that combining TTFields with Withaferin A would synergistically inhibit proliferation in glioblastoma. Human glioblastoma cells (GBM2, GBM39, U87-MG) and human breast adenocarcinoma cells (MDA-MB-231) were isolated from primary tumors. The glioma cell lines were genetically engineered to express firefly luciferase. Proliferative potential was assessed either by bioluminescence imaging or cell counting via hemocytometer. TTFields (4 V/cm) significantly inhibited growth of the four cancer cell lines tested (n=3 experiments per time point, 4 measurements per sample, p<0.02 at least; 2-way ANOVA, control vs. treatment). The combination of Withaferin A (10–100 nM) with TTFields significantly inhibited the growth of the glioma cells to a degree beyond that of Withaferin A or TTFields alone. The interaction of the Withaferin A and TTFields on glioma cells was found to be synergistic in nature (p<0.01, n=3 experiments). These findings were validated by both bioluminescence and hemocytometric measurements. The combination of Withaferin A with TTFields represents a novel approach to treat GBM in a manner that is likely better than either treatment alone and that is synergistic.
Quantifizierung von lokalem Materialabtrag/ Quantification of Localised Loss of Material (2000)

For a better understanding of the mechanism of erosion by arcing, an accurate method of quantifying the amount of material removed is required. To achieve this, a Scanning White Light Interference Microscope was used to measure the shape and volume of craters from their local depth profiles. The craters were produced using single arcs with defined physical characteristics. The investigations were carried out on the polished surfaces of various materials, and in particular alloys and intermetallic compounds. The vertical resolution of the interferometer used was of the order of 1 nm, while the lateral resolution using white light was limited to ca. 0.5 μm. This permits such craters to be measured quite accurately as their size generally varies between 20 and 500 nm in depth and 10 and 70 μm in diameter. A further advantage of this method is that in multi-phase structures the individual phases can be observed and the material loss can be distinguished between different phases.
Fundamental Limits to Extinction by Metallic Nanoparticles (2014)

We show that there are shape-independent upper bounds to the extinction cross section per unit volume of dilute, randomly arranged nanoparticles, given only material permittivity. Underlying the limits are restrictive sum rules that constrain the distribution of quasistatic eigenvalues. Surprisingly, optimally designed spheroids, with only a single quasistatic degree of freedom, reach the upper bounds for four permittivity values. Away from these permittivities, we demonstrate computationally optimized structures that surpass spheroids and approach the fundamental limits.
Nanoparticles with Raman Spectroscopic Fingerprints for DNA and RNA Detection* (2020)

Multiplexed detection of oligonucleotide targets has been performed with gold nanoparticle probes labeled with oligonucleotides and Raman-active dyes. The gold nanoparticles facilitate the formation of a silver coating that acts as a surface-enhanced Raman scattering promoter for the dye-labeled particles that have been captured by target molecules and an underlying chip in microarray format. The strategy provides the high-sensitivity and high-selectivity attributes 1468of grayscale scanometric detection but adds multiplexing and ratioing capabilities because a very large number of probes can be designed based on the concept of using a Raman tag as a narrow-band spectroscopic fingerprint. Six dissimilar DNA targets with six Raman-labeled nanoparticle probes were distinguished, as well as two RNA targets with single-nucleotide polymorphisms. The current unoptimized detection limit of this method is 20 femtomolar.
Lowest Electronic Excited States of Poly(para-cyclobutadienylenecyclopentadienylcobalt)butadiynylene (2000)

The copolymer poly(para-cyclobutadienylenecyclopentadienylcobalt)butadiynylene was studied with electronic absorption, Raman, and resonance Raman spectroscopies to determine the nature of the lowest visible absorbance in the optical spectrum. The electronic absorption suggests the presence of two major transitions within 5000 cm-1 of one another in the lowest energy absorption band. Vibrational assignments were made by comparing the 457.9 nm excited resonance Raman frequencies and depolarization ratios to ab initio calculations, and enhancement values were calculated. Depolarization ratios show that the Raman enhancement of several modes results from two or more electronic transitions. These data show that the C−C triple bonds experience significant excited-state distortion in at least one of these transitions. However, we also find that several other vibration modes exhibit significant enhancement upon electronic excitation. These changes are consistent with a charge-transfer assignment for one of the lowest energy singlet excited states between a nonbonding butadiene-centered orbital and an antibonding conjugated orbital. Because of metal involvement in the nonbonding orbital, this transition has significant MLCT character. A second transition is suggested that may be localized on the metal complex portion of the molecules.

3rd Continual Learning Workshop Challenge on Egocentric Category and Instance Level Object Understanding (2022)

Continual Learning, also known as Lifelong or Incremental Learning, has recently gained renewed interest among the Artificial Intelligence research community. Recent research efforts have quickly led to the design of novel algorithms able to reduce the impact of the catastrophic forgetting phenomenon in deep neural networks. Due to this surge of interest in the field, many competitions have been held in recent years, as they are an excellent opportunity to stimulate research in promising directions. This paper summarizes the ideas, design choices, rules, and results of the challenge held at the 3rd Continual Learning in Computer Vision (CLVision) Workshop at CVPR 2022. The focus of this competition is the complex continual object detection task, which is still underexplored in literature compared to classification tasks. The challenge is based on the challenge version of the novel EgoObjects dataset, a large-scale egocentric object dataset explicitly designed to benchmark continual learning algorithms for egocentric category-/instance-level object understanding, which covers more than 1k unique main objects and 250+ categories in around 100k video frames.
Tumor hypoxia induces nuclear paraspeckle formation through HIF-2α dependent transcriptional activation of NEAT1 leading to cancer cell survival (2014)

Activation of cellular transcriptional responses, mediated by hypoxia-inducible factor (HIF), is common in many types of cancer, and generally confers a poor prognosis. Known to induce many hundreds of protein-coding genes, HIF has also recently been shown to be a key regulator of the non-coding transcriptional response. Here, we show that NEAT1 long non-coding RNA (lncRNA) is a direct transcriptional target of HIF in many breast cancer cell lines and in solid tumors. Unlike previously described lncRNAs, NEAT1 is regulated principally by HIF-2 rather than by HIF-1. NEAT1 is a nuclear lncRNA that is an essential structural component of paraspeckles and the hypoxic induction of NEAT1 induces paraspeckle formation in a manner that is dependent upon both NEAT1 and on HIF-2. Paraspeckles are multifunction nuclear structures that sequester transcriptionally active proteins as well as RNA transcripts that have been subjected to adenosine-to-inosine (A-to-I) editing. We show that the nuclear retention of one such transcript, F11R (also known as junctional adhesion molecule 1, JAM1), in hypoxia is dependent upon the hypoxic increase in NEAT1, thereby conferring a novel mechanism of HIF-dependent gene regulation. Induction of NEAT1 in hypoxia also leads to accelerated cellular proliferation, improved clonogenic survival and reduced apoptosis, all of which are hallmarks of increased tumorigenesis. Furthermore, in patients with breast cancer, high tumor NEAT1 expression correlates with poor survival. Taken together, these results indicate a new role for HIF transcriptional pathways in the regulation of nuclear structure and that this contributes to the pro-tumorigenic hypoxia-phenotype in breast cancer.
Postoperative Management and Radiography (2015)

In the early postoperative period, good pain control is essential. Regimes of pain management appropriate for total knee arthroplasty may not be suited to the very rapid mobilisation that is possible after UKA through a minimally invasive approach. A multimodal approach is best with minimal opiate use. Different regimes are used successfully in different institutions.
Vejledning i længerevarende fællesfaglige forløb i naturfag: værktøjer og artefaktbasering (2017)

Nye lærere i folkeskolens naturfag skal kunne vejlede elever i fællesfagligt problembaseret arbejde. For at støtte dette har vi i læreruddannelsesregi udviklet et begreb om artefaktbaseret vejledning - og afprøvet en række værktøjer, som sætter fokus på forskellige kritiske aspekter (faglig integration, selvtillid ift fællesfagligt arbejde, gruppeproces). Divers empiri er indsamlet fra et hold lærerstuderende ifm et fællesfagligt specialiseringsmodul, bl.a. i tilknytning til vejledninger, praksisindslag i form af skoleovertagelse, hhv. casebaserede rollespil. Udover de konkrete værktøjer viser projektet, at artefaktbaserede tilgange sætter lærerstuderende i stand til at bruge værktøjerne til at identificere fællesfaglige vejledningsproblemer og som afsæt for at udvikle strategier for at tackle disse.
