Cationic Triple‐Decker Complexes with a Bridging 4‐Borataborepine Ligand: Synthesis, Structure, and Bonding (2008)

Abstract Cationic 30 VE triple‐decker complexes [Cp*Ru(μ‐η 7 :η 7 ‐C 5 B 2 Me 6 H)ML] + [ML = Co(C 4 Me 4 ) ( 3a ), RuCp* ( 4a ), Rh(cod) ( 7a ), and Ir(cod) ( 8a )] with a bridging hexamethyl‐4‐borataborepine ligand were obtained by electrophilic stacking of the sandwich compound Cp*Ru(η 7 ‐C 5 B 2 Me 6 H) ( 2a ) with [ML] + complex fragments. The reaction of the phenyl‐substituted derivative Cp*Ru(η 7 ‐7‐PhC 5 B 2 Me 5 H) ( 2b ) with [(C 4 Me 4 )Co(MeCN) 3 ] + selectively affords the triple‐decker complex [Cp*Ru(μ‐η 7 :η 7 ‐7‐PhC 5 B 2 Me 5 H)Co(C 4 Me 4 )] + ( 3b ), whereas a similar reaction with [Cp*RuCl] 4 /TlBF 4 produces a 1:3 mixture of cations, the triple‐decker [Cp*Ru(μ‐η 7 :η 7 ‐7‐PhC 5 B 2 Me 5 H)RuCp*] + ( 4b ) and the arene‐coordinated [Cp*Ru(μ‐η 6 :η 7 ‐7‐PhC 5 B 2 Me 5 H)RuCp*] + ( 5 ). Stacking of Cp*Ru(η 7 ‐7‐PhCH 2 C 5 B 2 Me 5 H) ( 2c ) with [CpRu(MeCN) 3 ] + selectively gives the triple‐decker complex [Cp*Ru(μ‐η 7 :η 7 ‐7‐PhCH 2 C 5 B 2 Me 5 H)RuCp] + ( 6c ). The dinuclear cations 3 – 8 were isolated as deep‐colored air‐stable salts with [BF 4 ] – or [PF 6 ] – anions in moderate to high yields. Structures of 3b PF 6 , 4a BF 4 , 7a BF 4 , and 8a BF 4 were confirmed by X‐ray diffraction studies. Energy decomposition analysis of complexes CpRu(ring) and [CpRu(ring)RuCp] + (ring = Cp, C 5 BH 6 , C 5 B 2 H 7 ) revealed that the insertion of BH units makes the bonding between [ring] – and [RuCp] + more covalent. According to Mulliken population analysis, weakening of π‐donation and strengthening of δ‐back donation occur in the same order. The electrostatic character of the bond and the contribution of σ‐donation to the covalent bonding are higher in the case of bifacially bonded rings. The boron‐containing triple‐decker complexes are considerably more stable than the cyclopentadienyl analog. (© Wiley‐VCH Verlag GmbH &amp; Co. KGaA, 69451 Weinheim, Germany, 2008)
Theoretical investigation of Fe substitution for Mn in complex hydride YMn2H6 (2012)

Complex hydride YMn2H6 with a space group Fm3¯m has two sorts of Mn, in which one presents as a divalent cation Mn2+ on the 8c site and the other forms a complex anion [MnH6]5− on the 4a site. We investigate the stabilities of Fe substitutions for a part of Mn atoms on either the site using first-principles calculations. Our results reveal that an Fe atom prefers the 4a occupation, and the origin of this site preference can be understood by the balance of two competing energy gains brought by the 3d bands for either the 4a or 8c site substituted Fe.
An Overview of Elastography-An Emerging Branch of Medical Imaging (2011)

From times immemorial manual palpation served as a source of information on the state of soft tissues and allowed detection of various diseases accompanied by changes in tissue elasticity. During the last two decades, the ancient art of palpation gained new life due to numerous emerging elasticity imaging (EI) methods. Areas of applications of EI in medical diagnostics and treatment monitoring are steadily expanding. Elasticity imaging methods are emerging as commercial applications, a true testament to the progress and importance of the field.In this paper we present a brief history and theoretical basis of EI, describe various techniques of EI and, analyze their advantages and limitations, and overview main clinical applications. We present a classification of elasticity measurement and imaging techniques based on the methods used for generating a stress in the tissue (external mechanical force, internal ultrasound radiation force, or an internal endogenous force), and measurement of the tissue response. The measurement method can be performed using differing physical principles including magnetic resonance imaging (MRI), ultrasound imaging, X-ray imaging, optical and acoustic signals.Until recently, EI was largely a research method used by a few select institutions having the special equipment needed to perform the studies. Since 2005 however, increasing numbers of mainstream manufacturers have added EI to their ultrasound systems so that today the majority of manufacturers offer some sort of Elastography or tissue stiffness imaging on their clinical systems. Now it is safe to say that some sort of elasticity imaging may be performed on virtually all types of focal and diffuse disease. Most of the new applications are still in the early stages of research, but a few are becoming common applications in clinical practice.
Experimental Verification of Null-Space Expansion for Multiuser Massive MIMO via Channel State Information Measurement (2017)

This paper presents experimental results of our proposed null-space expansion scheme for multiuser massive multiple-input multiple-output (MIMO) in time varying channels. Multiuser MIMO transmission with the proposed scheme can suppress the inter-user interference (IUI) caused by outdated channel state information (CSI). The excess degrees of freedom (DoFs) of massive MIMO is exploited to perform additional null-steering using past estimated CSI. The signal-to-interference power ratio (SIR) and spectral efficiency performances achieved by the proposed scheme that uses measured CSI is experimentally evaluated. It is confirmed that the proposed scheme shows performance superior to the conventional channel prediction scheme. In addition, IUI can be stably suppressed even in high mobility environments by further increasing the null-space dimension.
The impact of reduction of doublet well spacing on the Net Present Value and the life time of fluvial Hot Sedimentary Aquifer doublets (2017)

This paper evaluates the impact of reduction of doublet well spacing, below the current West Netherlands Basin standard of 1000–1500 m, on the Net Present Value (NPV) and the life time of fluvial Hot Sedimentary Aquifer (HSA) doublets. First, a sensitivity analysis is used to show the possible advantage of such reduction on the NPV. The parameter value ranges are derived from West Netherlands Basin HSA doublet examples. The results indicate that a reduction of well spacing from 1400 to 1000 m could already improve NPV by up to 15%. This effect would be larger in more marginally economic HSA doublets compared to the West Netherlands Basin base case scenario. The possibility to reduce well spacing is supported by finite element production simulations, utilizing detailed facies architecture models. Furthermore, our results underline the necessity of detailed facies architecture models to assess the potential and risks of HSA doublets. This factor significantly affects doublet life time and net energy production of the doublet.
Silver nanoparticles in polymeric matrices for fresh food packaging (2016)

The growing demand for increased fresh food shelf life as well as the need of protection against foodborne diseases urged the development of antimicrobial food packaging. Among the most efficient methods, the combination of organic–inorganic, packaging, i.e. polymer embedded metal nanoparticles proved to be highly effective. Silver nanoparticles (AgNPs), in particular, have antimicrobial, anti-fungi, anti-yeasts and anti-viral activities and can be combined with both non-degradable and edible polymers for active food packaging. The actual application of AgNPs in food packaging is regulated by EU and USA food safety authorities in a prudent way, due to the inability to make conclusive statements on their toxicity. Therefore, their use is evaluated in terms of Ag+ migration into the packed food. In this mini review, the most recent studies are reported on protection of meat, fruit and dairy products against the most common food pathogens by AgNPs-doped non-degradable and edible polymers and oils are reported.
Improved Catalysts for the Iridium‐Catalyzed Asymmetric Isomerization of Primary Allylic Alcohols Based on Charton Analysis (2010)

An improved generation of chiral cationic iridium catalysts for the asymmetric isomerization of primary allylic alcohols is disclosed. The design of these air-stable complexes relied on the preliminary mechanistic information available, and on Charton analyses using two preceding generations of iridium catalysts developed for this highly challenging transformation. Sterically unbiased chiral aldehydes that were not accessible previously have been obtained with high levels of enantioselectivity, thus validating the initial hypothesis regarding the selected ligand-design elements. A rationale for the high enantioselectivities achieved in most cases is also presented.
Efficacy and safety of imipenem/cilastatin in the empirical treatment of septicemia. (1987)

The clinical efficacy and safety of imipenem/cilastatin in the empirical treatment of adult non-immunocompromised patients with severe bacterial septicemia was studied in a prospective and open trial. The dosage of imipenem/cilastatin was 500 mg q 6 h. Of 58 patients included, 41 were evaluable for efficacy. In those patients, 35 had chronic underlying diseases and the foci of bacteremia were identified in 37; the most common ones being cardiovascular, urologic or intraabdominal infections. All isolated organisms were sensitive to imipenem with an MIC for 90% of the strains of 1 mg/l. Imipenem/cilastatin treatment resulted in rapid control of the infections in 39 of the 41 evaluable patients (95.5%). In the remaining two patients treatment had to be prematurely discontinued due to adverse effects. The causative bacterial strains were eradicated from blood in all patients who received more than one day of imipenem/cilastatin treatment but persisted sensitive to imipenem in peripheral foci in five patients (17%). Clinical and laboratory adverse reactions were noted in seven patients. In conclusion, imipenem/cilastatin was a well tolerated and effective empirical drug for treatment of septicemia.

Low-level overexpression of wild type TDP-43 causes late-onset, progressive neurodegeneration and paralysis in mice (2021)

Abstract Modestly increased expression of transactive response DNA binding protein ( TDP-43 ) gene have been reported in amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and other neuromuscular diseases. However, whether this modest elevation triggers neurodegeneration is not known. Although high levels of TDP-43 overexpression have been modeled in mice and shown to cause early death, models with low-level overexpression that mimic the human condition have not been established. In this study, transgenic mice overexpressing wild type TDP-43 at less than 60% above the endogenous CNS levels were constructed, and their phenotypes analyzed by a variety of techniques, including biochemical, molecular, histological, behavioral techniques and electromyography. The TDP-43 transgene was expressed in neurons, astrocytes, and oligodendrocytes in the cortex and predominantly in astrocytes and oligodendrocytes in the spinal cord. The mice developed a reproducible progressive weakness ending in paralysis in mid-life. Detailed analysis showed ∼30% loss of large pyramidal neurons in the layer V motor cortex; in the spinal cord, severe demyelination was accompanied by oligodendrocyte injury, protein aggregation, astrogliosis and microgliosis, and elevation of neuroinflammation. Surprisingly, there was no loss of lower motor neurons in the lumbar spinal cord despite the complete paralysis of the hindlimbs. However, denervation was detected at the neuromuscular junction. These results demonstrate that low-level TDP-43 overexpression can cause diverse aspects of ALS, including late-onset and progressive motor dysfunction, neuroinflammation, and neurodegeneration. Our findings suggest that persistent modest elevations in TDP-43 expression can lead to ALS and other neurological disorders involving TDP-43 proteinopathy. Because of the predictable and progressive clinical paralytic phenotype, this transgenic mouse model will be useful in preclinical trial of therapeutics targeting neurological disorders associated with elevated levels of TDP-43.

CdS nanorod arrays with TiO2 nano-coating for improved photostability and photocatalytic activity (2014)

CdS nanorod arrays were grown on fluorine-doped tin oxide glass substrates via a hydrothermal process and subsequently coated with a TiO2 nanolayer via a vacuum dip-coating process to fabricate a one-dimensional array structured photocatalyst. The TiO2 nanolayer improved the photocatalytic efficiency of CdS nanorod arrays for the degradation of methylene blue due to the effective separation of the electron-hole pairs, and the photocorrosion of CdS nanorod arrays was successfully inhibited.
RISK FACTORS FOR SPONTANEOUS ABORTION AND ITS RECURRENCE (1988)

Pregnancy histories of women interviewed as normal population controls during 1974-1981 in four case-control studies in the US and Canada were examined to identify risk factors for the occurrence of miscarriage. In total, 2,068 ever-gravid women aged 20-79 years at interview (mean age, 50.3 years) described 6,282 pregnancies, including 805 miscarriages. The roles of previous pregnancy history, age at pregnancy, and other factors were evaluated using relative risk binomial regression methods (similar to logistic regression). Risk of miscarriage during a given pregnancy was found to increase directly with the number of previous miscarriages (the risk was closely approximated by (1 + number of prior miscarriages)1.01), but appeared to be unrelated to the order of miscarriages within all previous pregnancies. Maternal age was also highly related to risk after controlling for gravidity and previous miscarriages, with doubled risk (compared with age 20 years) seen for pregnancies in women older than age 40 years. Risk of miscarriage did not appear to be associated with years since previous pregnancy, height, weight or obesity, use of oral contraceptives within one year before pregnancy, or duration of oral contraceptive use. A slight increase in risk was seen for women who had ever regularly smoked cigarettes (relative risk = 1.14, 95 per cent confidence limits = 1.00, 1.30). Thus, the levels of risk of miscarriage found in this analysis are similar to those of previous studies, and the analytic methods suggest how age, obstetric history, and other factors can be simultaneously examined for associations with such risk.
<title>Determination of nematics material parameters by measurements of Fredericksz transitions in crossed electric and magnetic fields in wedge cell</title> (2004)

Wedge cells of the wedge angle of order of few milliradians were used to measure the threshold voltages for the Freedericksz transition in electric and magnetic fields crossed. A nematic liquid crystal, PCB, filling cells was of planar orientation enforced by the treatment of the flat boundary plates, covered with poly(amic acid) PM9. A system of interference fringes appeared in each cell placed in normally incident light between analyzer and polarizer crossed. In the vicinity of each fringe a cell could be considered as a flat-parallel one and hence it was equivalent to the system of flat cells of different precisely determined thickness. Threshold voltages, parameterized by magnetic field magnitudes were interpreted as the eigenvalues of the boundary eigenvalue problem for the operator of the second derivative; the interaction between the nematics and the substrates was assumed very strong with the anchoring direction parallel to the cell boundaries. The resulting formulae were used to determine the anisotropy of diamagnetic susceptibility and the splay elastic constant of PCB after the threshold magnitudes measured. The estimates of material parameters agreed well with those determined by the composite method.
Immune Response to Rotavirus and Gluten Sensitivity (2018)

<i>Rotavirus</i> is a double-stranded RNA virus belonging to the family of <i>Reoviridae</i>. The virus is transmitted by the faecal-oral route and infects intestinal cells causing gastroenteritis. Rotaviruses are the main cause of severe acute diarrhoea in children less than 5 years of age worldwide. In our previous work we have shown a link between rotavirus infection and celiac disease. Nonceliac gluten sensitivity (NCGS) is emerging as new clinical entity lacking specific diagnostic biomarkers which has been reported to occur in 6-10% of the population. Clinical manifestations include gastrointestinal and/or extraintestinal symptoms which recede with gluten withdrawal. The pathogenesis of the disease is still unknown. Aim of this work is to clarify some aspects of its pathogenesis using a gene array approach. Our results suggest that NCGS may have an autoimmune origin. This is based both on gene expression data (i.e., TH17-interferon signatures) and on the presence of TH17 cells and of serological markers of autoimmunity in NCGS. Our results also indicate a possible involvement of <i>rotavirus</i> infection in the pathogenesis of nonceliac gluten sensitivity similarly to what we have previously shown in celiac disease.
First-principles study on nonlocal ferromagnetism in (Cu, N)-codoped ZnO (2013)

First-principles calculations based on spin density functional theory are performed to study the spin-resolved electronic properties of ZnO codoped with Cu and N. (Cu, N)-codoped ZnO exhibits magnetism, and the total magnetic moment mainly originates from the p—d hybridization of Cu—N and Cu—O as well as p—p coupling interaction between N and O at the Fermi level. The Zn34Cu2O35N1 favors energetically a ferromagnetic ground state due to the existence of stable Cu—N—Cu complex. These results imply that the (Cu, N)-codoped ZnO is a promising dilute magnetic semiconductor free of magnetic precipitates, which could broaden the horizon of currently known magnetic systems.
Deciphering the laws of social network-transcendent COVID-19 misinformation dynamics and implications for combating misinformation phenomena (2021)

The global rise of COVID-19 health risk has triggered the related misinformation infodemic. We present the first analysis of COVID-19 misinformation networks and determine few of its implications. Firstly, we analyze the spread trends of COVID-19 misinformation and discover that the COVID-19 misinformation statistics are well fitted by a log-normal distribution. Secondly, we form misinformation networks by taking individual misinformation as a node and similarity between misinformation nodes as links, and we decipher the laws of COVID-19 misinformation network evolution: (1) We discover that misinformation evolves to optimize the network information transfer over time with the sacrifice of robustness. (2) We demonstrate the co-existence of fit get richer and rich get richer phenomena in misinformation networks. (3) We show that a misinformation network evolution with node deletion mechanism captures well the public attention shift on social media. Lastly, we present a network science inspired deep learning framework to accurately predict which Twitter posts are likely to become central nodes (i.e., high centrality) in a misinformation network from only one sentence without the need to know the whole network topology. With the network analysis and the central node prediction, we propose that if we correctly suppress certain central nodes in the misinformation network, the information transfer of network would be severely impacted.
Solfeggi and the Acquisition of Style (2020)

Abstract In the old conservatories the equivalent of “music 101” was the class in solfeggio. This was where beginning students learned to read music, to distinguish the sizes of intervals, and to learn scales and arpeggios. Today syllables like “Do, Re, Mi” are connected with scale degrees (steps 1, 2, 3 respectively). This was not the case originally. “Mi,” for example, meant a tone with a whole step below it in the scale and a half step above it. Thus both “E,” “B,” and “F♯” were all “Mi.” Similarly, “F,” “C,” and “B♭” were all “Fa.” The chapter details how this worked and gives examples of lessons in the old style of solfeggio.
Chiral Separation by Capillary Electrochromatography Using Cyclodextrin Phases (2004)

Cyclodextrin and its derivatives are well known chiral selectors in gas chromatography (GC), high-performance liquid chromatography (HPLC), capillary electrophoresis (CE), and also in capillary electrochromatography (CEC), a hybrid method of CE and liquid chromatography (LC). The separation of enantiomers by CEC on cyclodextrin stationary phases (1–4) can be achieved by three different methods: (i) open tubular capillary electrochromatography (o-CEC); (ii) packed capillary electrochromatography (p-CEC); and (iii) rod-CEC. In o-CEC, the internal capillary wall is coated with the chiral stationary phase (see Fig. 1), e.g., with Chirasil-Dex (see Fig. 2), which is a permethyl-β-cyclodextrin covalently linked via a spacer to dimethylpolysiloxane (4–6). For p-CEC, using capillaries filled with typical chiral HPLC packing materials, two different techniques for fixing cyclodextrins or its derivatives to the silica are described: (i) the cyclodextrin or its derivatives are covalently bound via a spacer to the silica particles (4,7) (e.g., Chira-Dex-silica [see Fig. 2]); or (ii) Chirasil-Dex is immobilized on the silica material (4,8). The packing bed is held in position by frits, and detection occurs in the empty part of the capillary (see Fig. 1). In rod-CEC, columns consisting of a porous solid prepared by an in situ sol-gel-process (9) or by sintering of silica (10) were used. For enantiomer separation, the resulting monolith is derivatized with Chirasil-Dex (9,10) (see Fig. 1).
Software Defined Channel Sounder for Power Line Communications (2016)

Most power line channel sounders are based on expensive lab instruments. This work presents an alternative based on software defined radio platforms. These can be later also employed as communication modems, decreasing costs and deployment times. We implemented and evaluated two channel sounding techniques: frequency hopping and sliding correlator. The results suggest that frequency hopping might be a better candidate for power line channels due to the expected low signal-to-noise ratio.
Effect of Fermentation on Proteins of Swedish Fermented Milk Products (1982)
