One Picture is Worth a Thousand Words: A New Wallet Recovery Process (2022)

We introduce a new wallet recovery pro-cess. Our solution associates 1) visual passwords: a photograph ofa secretly picked object (Chabanne et aI., 2013) with 2) ImageNet classifiers transforming images into binary vectors and, 3) obfuscated fuzzy matching (Galbraith and Zobernig, 2019) for the storage of visual passwords/retrieval of wallet seeds. Our experiments show that the replacement of long seed phrases by a photograph is possible.
Chemical modulation of microtubule structure through the laulimalide/peloruside site (2022)

Taxanes are microtubule-stabilizing agents used in the treatment of many solid tumors, but they often involve side effects affecting the peripheral nervous system. It has been proposed that this could be related to structural modifications on the filament upon drug binding. Alternatively, laulimalide and peloruside bind to a different site also inducing stabilization, but they have not been exploited in clinics. Here, we use a combination of the parental natural compounds and derived analogs to unravel the stabilization mechanism through this site. These drugs settle lateral interactions without engaging the M loop, which is part of the key and lock involved in the inter-protofilament contacts. Importantly, these drugs can modulate the angle between protofilaments, producing microtubules of different diameters. Among the compounds studied, we have found some showing low cytotoxicity and able to induce stabilization without compromising microtubule native structure. This opens the window of new applications for microtubule-stabilizing agents beyond cancer treatment.
Allergens from birch pollen and pollen of the European chestnut share common epitopes (1993)

Summary Type I allergy to pollen of the European chestnut ( Castanea sativa ) represents a major cause of pollinosis in (sub) Mediterranean areas. Using sera from 14 patients with established allergy to pollen of the European chestnut, 13/14 sera (92%) showed IgE‐binding to a 22 kD protein, 2/14(14%) displayed additional binding to a 14 kD protein and 1/14 (7%) bound only to the 14 kD protein of European chestnut pollen extract. Two monoclonal mouse antibodies, BIP 1 and BIP 4, directed against different epitopes of Bet v I (the major birch pollen allergen), and a rabbit antibody to recombinant birch profilin (r Bet v II) were used to characterize the proteins of the European chestnut pollen. The recombinant birch pollen allergens, r Bet v I and r Bet v II (profilin) were employed to show common allergenic structures on proteins from both birch and European chestnut pollen by IgE‐inhibition experiments. Despite the fact that the 22 kD protein displayed a higher molecular weight in comparison to the 17 kD major birch pollen allergen, Bet v I, we could demonstrate reactivity of both monoclonal antibodies, BIP 1 and BIP 4, with this protein. A complete inhibiton of IgE‐binding to this 22 kD protein was shown by pre‐incubating sera with purified recombinant Set r I. In addition, the 14kD protein could be identified by IgE‐inhibition studies with recombinant Bet v II and by using a rabbit anti‐profilin antibody as the profilin from pollen of the European chestnut.
Comparative study of two-mode frequency and amplitude stabilized He-Ne lasers (1984)

Frequency and amplitude stablization of commercially available internal mirror He-Ne lasers is of interest for many interferometric measurements in scientific laboratories and industries. A number of schemes have been devised and reported in the literature. In particular, those lasers oscillating in two modes can be frequency stablized by balancing the output power of the two modes, the polarizations of which are mutually perpenducular. Typically a stability of a few parts in 108 over several hours can be readily achieved. Recently Sasaki has described a method in which the total back beam intensity of the laser was monitored and a feedback signal applied either to a fan or heater which controls the laser tube length. A relative amplitude stability of ≤ 0.16% and relative frequency stability of ± 9×10−9 are obtained for a period of 10 minutes or longer.
Investigating the Effects of Multiple Pilot Injections on Stability at Cold Idle for a Dl Diesel Engine (2009)

&lt;div class="htmlview paragraph"&gt;An experimental investigation of combustion cycle-by-cycle stability under cold idling conditions has been carried out on a Dl diesel to examine the influence of pilot fuel injection strategy. The engine is a single cylinder variant of a multi-cylinder design meeting Euro 4 emissions requirements. The engine build had a swept volume of 500cc and a compression ratio of 18.4:1. Work output and heat release characteristics have been investigated at test temperatures of 10, 0, −10 and −20°&lt;i&gt;C&lt;/i&gt; and speeds in the range from 600 to 1400rpm. At the lowest temperature, −20°&lt;i&gt;C&lt;/i&gt;, stability is sensitive to the timing of main injection and is prone to deteriorate with increasing engine speed. The influence of the number of pilot injections and pilot fuel quantity on stability has been explored. Best stability was achieved by increasing the number of pilot injections as temperature is lowered, from one at 10°&lt;i&gt;C&lt;/i&gt; to two at −10°&lt;i&gt;C&lt;/i&gt; and between two and four at −20°&lt;i&gt;C&lt;/i&gt;. At the lowest temperature, triple or quadruple pilot injections can broaden the region of stable operation across a range of injection timings and engine speeds. Heat release analysis shows that there is less cycle by cycle variation in phasing and cumulative heat release when multiple pilots are used.&lt;/div&gt;
Occurrence of Disinfection Byproducts in United States Wastewater Treatment Plant Effluents (2009)

Effluents from wastewater treatment plants (WWTPs) contain disinfection byproducts (DBPs) of health concern when the water is utilized downstream as a potable water supply. The pattern of DBP formation was strongly affected by whether or not the WWTP achieved good nitrification. Chlorine addition to poorly nitrified effluents formed low levels of halogenated DBPs, except for (in some cases) dihalogenated acetic acids, but often substantial amounts of N-nitrosodimethyamine (NDMA). Chlorination of well-nitrified effluent typically resulted in substantial formation of halogenated DBPs but much less NDMA. For example, on a median basis after chlorine addition, the well-nitrified effluents had 57 microg/L of trihalomethanes [THMs] and 3 ng/L of NDMA, while the poorly nitrified effluents had 2 microg/L of THMs and 11 ng/L of NDMA. DBPs with amino acid precursors (haloacetonitriles, haloacetaldehydes) formed at substantial levels after chlorination of well-nitrified effluent. The formation of halogenated DBPs but not that of NDMA correlated with the formation of THMs in WWTP effluents disinfected with free chlorine. However, THM formation did not correlate with the formation of other DBPs in effluents disinfected with chloramines. Because of the relatively high levels of bromide in treated wastewater, bromine incorporation was observed in various classes of DBPs.
Molecular Design Strategy of Thermally Activated Delayed Fluorescent Emitters Using CN‐Substituted Imidazopyrazine as a New Electron‐Accepting Unit (2019)

Thermally activated delayed fluorescence (TADF)-based organic light-emitting diodes (OLEDs) have attracted enormous attention recently due to their capability to replace conventional phosphorescent organic light-emitting diodes for practical applications. In this work, a newly designed CN-substituted imidazopyrazine moiety was utilized as an electron-accepting unit in a TADF emitter. Two TADF emitters, 8-(3-cyano-4-(9,9-dimethylacridin-10(9H)-yl)phenyl)-2-phenylimidazo[1,2-a]pyrazine-3-carbonitrile (Ac-CNImPyr) and 8-(3-cyano-4-(10H-phenoxazin-10-yl)phenyl)-2-phenylimidazo[1,2-a]pyrazine-3-carbonitrile (PXZ-CNImPyr), were developed based on the CN-substituted imidazopyrazine acceptor combined with acridine and phenoxazine donor, respectively. A CN-substituted phenyl spacer was introduced between the donor and acceptor for a sufficiently small singlet-triplet energy gap (ΔE<sub>ST</sub> ) and molecular orbital management. Small ΔE<sub>ST</sub> of 0.07 eV was achieved for the phenoxazine donor-based PXZ-CNImPyr emitter. As a result, an organic light-emitting diode based on the PXZ-CNImPyr emitter exhibited a high external quantum efficiency of up to 12.7 %, which surpassed the EQE limit of common fluorescent emitters. Hence, the CN-modified imidazopyrazine unit can be introduced as a new acceptor for further modifications to develop efficient TADF-based OLEDs.
A balloon-borne survey of the mm/sub-mm sky: OLIMPO (2005)

The main objective of the OLIMPO project, a large stratospheric telescope, is the measurement of the Sunyaev-Zeldovich effect in many clusters of galaxies during a long-duration balloon flight. We describe the OLIMPO experiment, and outline the scientific rationale of balloon-borne measurements of the effect.
Leucocyte Alkaline Phosphatase Elevation in Human Acute Leukaemia Derived Cell Lines Cultured in Diffusion Chambers (1977)

Leucocyte alkaline phosphatase (LAP) was histochemically detected in 7 to 18% of cells in tissue culture lines derived from the peripheral blood or bone marrow of each of 5 patients with untreated acute myelogenous or monomyelogenous leukaemia and in 30% of the cells in a clonal line of a rat promyelocytic leukaemia. Following transfer to diffusion chambers intraperitoneally implanted into total body irradiated rats, LAP levels were detected in up to 92% of human and 80% of rat leucocytes. There was no associated morphologic differentiation. In rat leukaemia cells peroxidase and myeloid specific esterase also increased from tissue culture levels. Return of cells to tissue culture decreased enzymes to pre-implant levels. Addition of plasma or peritoneal fluid from irradiated rats to cells in tissue culture again induced LAP. In contrast, LAP was not increased under these conditions with cell lines derived from patients with acute lymphatic leukaemia, or Sezary cell leukaemia. These studies indicate that a humoral factor in peritoneal fluid and plasma of irradiated rats increases LAP in human as well as rat leucocytes.
Constraints on Higgs boson production with large transverse momentum using $H\rightarrow b\bar{b}$ decays in the ATLAS detector (2021)

This paper reports constraints on Higgs boson production with transverse momentum above 1 TeV. The analyzed data from proton-proton collisions at a center-of-mass energy of 13 TeV were recorded with the ATLAS detector at the Large Hadron Collider from 2015 to 2018 and correspond to an integrated luminosity of 136 fb$^{-1}$. Higgs bosons decaying into $b\bar{b}$ are reconstructed as single large-radius jets recoiling against a hadronic system and identified by the experimental signature of two $b$-hadron decays. The experimental techniques are validated in the same kinematic regime using the $Z\rightarrow b\bar{b}$ process. The 95% confidence-level upper limit on the cross section for Higgs boson production with transverse momentum above 450 GeV is 115 fb, and above 1 TeV it is 9.6 fb. The Standard Model predictions in the same kinematic regions are 18.4 fb and 0.13 fb, respectively.

Zn(Cu): mp >400 °C; d ca. 7.14 g cm−3. Solubility: ClCH2I: sol organic solvents; insol H2O. Zn(Cu): insol organic solvents and H2O. Form Supplied in: ClCH2I: colorless to brown liquid. Zn(Cu): reddish-brown or dark gray powder; often prepared directly before use. Preparative Method: see Zinc/Copper Couple. Purification: chloroiodomethane can be purified by distillation. Handling, Storage, and Precautions: chloroiodomethane is light sensitive and should be stored in the dark. It can be stabilized with copper wire. Zinc–copper couple deteriorates in moist air and should be stored under nitrogen. Very active zinc–copper couple is oxygen sensitive. It evolves hydrogen on contact with strong aqueous acids.
Effect of Alkali and Alkaline Earth Metal Salts on Suppression of Lithium Dendrites (2014)

Lithium dendrites are needle-like structures that form during the electrodeposition of lithium metal. These whiskers complicate the use of lithium metal as an anode in lithium batteries because they can puncture the separator and short circuit the battery. In addition, the large surface area and poor adhesion of the deposit contributes to loss of coulombic efficiency. The effect of alkali and alkaline earth metal ions on the morphology of electrodeposited lithium metal has been studied. Varying concentrations of alkali and alkaline earth metal ions were added to a 1 M lithium bis(trifluoromethanesulfonyl)imide (Li-TFSI) trimethylbutylammonium bis(trifluoromethanesulfonyl)imide (N1114-TFSI) electrolyte. Lithium metal was electrodeposited from each electrolyte and examined ex-situ by scanning electron microscopy (SEM). Alkali metal ions, with the exception of sodium, had little or no effect on the deposited lithium morphology. However, alkaline earth metal ions at 0.05 M concentration significantly reduced the occurrence of dendrites. When the concentration of the alkaline earth metal ions was increased to 0.1 M, dendrites were completely eliminated and lithium was deposited in a sphere-like morphology. Energy dispersive X-ray spectroscopy (EDX) showed that no alkaline earth metals were found in the sphere-like deposits, suggesting that dendrite mitigation occurred through an adsorption mechanism.
Enhanced Proteolytic Activity of Covalently Bound Enzymes in Photopolymerized Sol Gel (2005)

Trypsin is covalently linked to a photopolymerized sol-gel monolith modified by incorporating poly(ethylene glycol) (PSG-PEG) for on-column digestion of N(alpha)-benzoyl-l-arginine ethyl ester (BAEE) and two peptides, neurotensin and insulin chain B. The coupling of the enzyme to the monolith is via room-temperature Schiff chemistry in which an alkoxysilane reagent (linker) with an aldehyde functional group links to an inactive amine on trypsin to form an imine bond. The proteolytic activity of the immobilized trypsin was measured by monitoring the formation of N alpha-benzoyl-L-arginine (BA), the digestion product of BAEE. The BA is separated from BAEE by capillary electrophoresis and detected downstream (18.5 cm from the microreactor) by absorption (254 nm). Using the Bradford assay, we determined that 97 ng of trypsin is bound to the 1-cm microreactor located at the entrance of capillary column. The bioactivity of the trypsin-PSG-PEG microreactor at 20 degrees C for the digestion of BAEE was found to be 2270 units/mg of immobilized trypsin. The bioactivity of trypsin bound to the capillary wall in the open segment upstream from the monolith was 332 units/mg of immobilized trypsin under the same conditions. In contrast, the activity of free trypsin could not be observed for the digestion of BAEE at 20 degrees C after 16 h of incubation time.
A 6-items Questionnaire (6-QMD) captures a Mediterranean like dietary pattern and is associated with memory performance and hippocampal volume in elderly and persons at risk for Alzheimer’s disease (2023)

BACKGROUND: There is evidence that adherence to Mediterranean-like diet reduces cognitive decline and brain atrophy in Alzheimer's disease (AD). However, lengthy dietary assessments, such as food frequency questionnaires (FFQs), discourage more frequent use. OBJECTIVE: Here we aimed to validate a 6-items short questionnaire for a Mediterranean-like diet (6-QMD) and explore its associations with memory performance and hippocampal atrophy in healthy elders and individuals at risk for AD. METHODS: We analyzed 938 participants (N = 234 healthy controls and N = 704 participants with an increased AD risk) from the DZNE-Longitudinal Cognitive Impairment and Dementia Study (DELCODE). The 6-QMD was validated against the Mediterranean Diet (MeDi) score and the Mediterranean-DASH Diet Intervention for Neurodegenerative Delay (MIND) score, both derived from a detailed FFQ. Furthermore, associations between the 6-QMD and memory function as well as hippocampal atrophy were evaluated using linear regressions. RESULTS: The 6-QMD was moderately associated with the FFQ-derived MeDi adherence score (ρ = 0.25, p &lt; 0.001) and the MIND score (ρ = 0.37, p= &lt; 0.001). Higher fish and olive oil consumption and lower meat and sausage consumption showed significant associations in a linear regression, adjusted for diagnosis, age, sex and education, with memory function (β = 0.1, p = 0.008) and bilateral hippocampal volumes (left: β = 0.15, p &lt; 0.001); (right: β = 0.18, p &lt; 0.001)). CONCLUSIONS: The 6-QMD is a useful and valid brief tool to assess the adherence to MeDi and MIND diets, capturing associations with memory function and brain atrophy in healthy elders and individuals at increased AD dementia risk, making it a valid alternative in settings with time constraints.
2D Correlation Spectroscopy (2DCoS) Analysis of Temperature-Dependent FTIR-ATR Spectra in Branched Polyethyleneimine/TEMPO-Oxidized Cellulose Nano-Fiber Xerogels (2021)

Fourier transform infrared spectroscopy in attenuated total reflectance geometry (FTIR-ATR), combined with a 2D correlation analysis, was here employed to investigate temperature-induced spectral changes occurring in a particular type of novel cellulosic-based nano-material prepared using 2,2,6,6-tetramethyl-piperidine-1-oxyl (TEMPO) oxidized and ultra-sonicated cellulose nano-fibers (TOUS-CNFs) as three-dimensional scaffolds, and branched polyethyleneimine (bPEI) as cross-linking agent. The aim was to highlight the complex sequential events involving the different functional groups of the polymeric network, as well as to gain insight into the interplay between the amount of bPEI and the resulting sponge-like material, upon increasing temperature. In this framework, synchronous and asynchronous 2D spectra were computed and analyzed in three wavenumber regions (900-1200 cm<sup>-1</sup>, 1500-1700 cm<sup>-1</sup> and 2680-3780 cm<sup>-1</sup>), where specific vibrational modes of the cellulosic structure fall, and over a T-range between 250 K and 340 K. A step-by-step evolution of the different arrangements of the polymer functional groups was proposed, with particular regard to how the cooperativity degree of inter- and intramolecular hydrogen bonds (HBs) changes upon heating. Information acquired can be useful, in principle, in order to develop a next-generation, T-sensitive novel material to be used for water remediation applications or for drug-delivery nano-vectors.
Incompatibility of standard III–V compound semiconductor processing techniques with terbium-doped InGaAs of high terbium concentration (2012)

Terbium-doped InGaAs with a high terbium concentration shows promise as a high-efficiency thermoelectric material, with the thermal conductivity dropping to 1.27 W/m K at a TbAs concentration of 1.55% by number of atoms. However, large discrepancies are noted in Hall effect measurements on terbium-doped InGaAs grown by molecular beam epitaxy on InP substrate following standard III–V wet chemical processing techniques, when compared to samples with no processing beyond deposition of indium contacts. These discrepancies preclude systematic exposition of temperature- and composition-dependent thermoelectric figures of merit. The discrepancy is seen to be correlated with the terbium concentration and the thickness of the active material. The steps in the process sequence are examined under controlled conditions. Although the exact cause for the discrepancy has not been found, some of the obvious reasons have been ruled out. It is therefore surmised that (1) chemical reaction with photoresist, (2) ultraviolet irradiation during photolithography, or (3) reaction with photoresist developing solutions and HF are the factors responsible for the changes in Hall voltage. Evidence is presented for the creation of surface states that corrupt Hall effect measurements on the bulk semiconductor.
Impact of intravenous fluid administration on cardiac output and oxygenation during cardiopulmonary resuscitation (2023)

Administration of IVF during CPR resulted in a significant increase in CO during CPR both during and after the IVF infusion. There was no statistically significant decrease in PaO<sub>2</sub> between the IVF and control groups.
Detecting the performance impact of upgrades in large operational networks (2010)

Networks continue to change to support new applications, improve reliability and performance and reduce the operational cost. The changes are made to the network in the form of upgrades such as software or hardware upgrades, new network or service features and network configuration changes. It is crucial to monitor the network when upgrades are made because they can have a significant impact on network performance and if not monitored may lead to unexpected consequences in operational networks. This can be achieved manually for a small number of devices, but does not scale to large networks with hundreds or thousands of routers and extremely large number of different upgrades made on a regular basis. In this paper, we design and implement a novel infrastructure MERCURY for detecting the impact of network upgrades (or triggers) on performance. MERCURY extracts interesting triggers from a large number of network maintenance activities. It then identifies behavior changes in network performance caused by the triggers. It uses statistical rule mining and network configuration to identify commonality across the behavior changes. We systematically evaluate MERCURY using data collected at a large tier-1 ISP network. By comparing to operational practice, we show that MERCURY is able to capture the interesting triggers and behavior changes induced by the triggers. In some cases, MERCURY also discovers previously unknown network behaviors demonstrating the effectiveness in identifying network conditions flying under the radar.
Flexible Sensors Based on (2013)

Flexible sensors can be envisioned as promising components for smart sensing applications, including consumer electronics, robotics, prosthetics, health care, safety equipment, environmental monitor- ing, homeland security and space flight. The current review presents a concise, although admittedly nonexhaustive, didactic review of some of the main concepts and approaches related to the use of nanoparticles (NPs) in flexible sensors. The review attempts to pull together different views and terminologies used in the NP-based sensors, mainly those established via electrical transduction approaches, including, but, not confined to: (i) strain-gauges, (ii) flexible multiparametric sensors, and (iii) sensors that are unaffected by mechanical deformation. For each category, the review presents and discusses the common fabrication approaches and state-of-the-art results. The advantages, weak points, and possible routes for future research, highlighting the challenges for NP-based flexible sensors, are presented and discussed as well.
