Optical anisotropy of non-common-atom quantum wells and dots: effects of interface symmetry reduction (2003)

We report on the investigations of in-plane optical anisotropy in non-common-atom heterostructures: ZnSe/BeTe perfect quantum wells (QWs) and CdSe/BeTe rough QWs and quantum dots. A noticeable linear polarization of photoluminescence (PL) with respect to the in-plane [1–10] and [110] crystal axes was observed in the ZnSe/BeTe QWs with equivalent ZnTe-type interfaces due to the reduction of QW symmetry, induced by unintentional formation of BeSe chemical bonds at a “BeTe-ZnSe” interface. The BeSe bond concentration and, hence, the polarization degree depend on the Te/Be flux ratio during molecular beam epitaxy growth of the samples. Strongly linearly polarized (up to 80%) PL was detected in the CdSe/BeTe structures, evidencing QW-like flat symmetry of the emitting sites of carrier localization.
A transmissible feline fibrosarcoma of viral origin. (1971)

Summary Histological examination of an invasive neoplasm from an 18-month-old female domestic shorthair cat revealed it to be a pleomorphic fibrosarcoma that ranged in microscopic appearance from well-differentiated collagenous connective tissue to anaplastic sarcomatous tissue that infiltrated surrounding musculature and skin. The fibrosarcoma was transmitted by whole cells or cell-free preparations to 8 to 10 neonatal kittens. The original neoplasm and the induced fibrosarcomas that were examined electron microscopically contained mature and budding C-type particles. Immunodiffusion studies with serum prepared in rabbits against purified ether-disrupted feline leukemia virus revealed identity between the feline leukemia virus group-specific antigen and extracts of the original fibrosarcoma.

Influence of Scene-Based Properties on Visual Search (1990)

The task of visual search is to determine as rapidly as possible whether a target item is present or absent in a display. Rapidly detected items are thought to contain features that correspond to primitive elements in the human visual system. In previous theories, it has been assumed that visual search is based on simple two-dimensional features in the image. However, visual search also has access to another level of representation, one that describes properties in the corresponding three-dimensional scene. Among these properties are three dimensionality and the direction of lighting, but not viewing direction. These findings imply that the parallel processes of early vision are much more sophisticated than previously assumed.

Preface (2012)

The radio spectrum is one of the most important resources for communications. Traditionally, spectrum governance throughout the world has tended towards exclusivity of its use in large geographic areas, allocating frequency bands for specific applications and assigning licenses to specific users or service providers. This policy has generated a shortage of frequencies available for emerging wireless products and services, as most frequencies are now assigned. Moreover, exclusivity creates underutilization of the spectrum, as very rarely can all licensees make full use of the frequencies assigned to them. These facts have motivated the search for technologies able to alleviate the artificial scarcity of spectrum by adapting to changing environmental and network-usage conditions.
Equation of motion theory for excited states in variational Monte Carlo and the Jastrow antisymmetric geminal power in Hilbert space (2016)

An equation of motion formalism for excited states in variational Monte Carlo is derived and a pilot implementation for the Jastrow-modified antisymmetric geminal power is tested. In single excitations across a range of small molecules, this combination is shown to be intermediate in accuracy between configuration interaction singles and equation of motion coupled cluster with singles and doubles. For double excitations, energy errors are found to be similar to those for coupled cluster.
Assignment of Absolute Configurations of the Enantiomeric Spiroiminodihydantoin Nucleobases by Experimental and Computational Optical Rotatory Dispersion Methods (2006)

The diastereomeric spiroiminodihydantoin (Sp) lesions are oxidation products of guanine and 8-oxo-7,8-dihydroguanine (8-oxoG) and have generated considerable interest because of their stereochemistry-dependent mutagenic properties in vivo (Henderson, P. T., et al. (2003) Biochemistry 42, 9257-9262). However, the absolute configurations of the two diastereomers have not yet been elucidated, and such information may prove valuable for understanding relationships between biological function and structure at the DNA level (Jia, L., Shafirovich, V., Shapiro, R., Geacintov, N. E., and Broyde, S. (2005) Biochemistry 44, 13342-13353). We have synthesized the two chiral Sp nucleobases by hydrolysis of the nucleosides denoted by dSp1 and dSp2 according to their elution order in HPLC experiments using a Hypercarb column, and determined their absolute configurations using a combination of experimentally measured optical rotatory dispersion (ORD) spectra in aqueous solutions and computed ORD specific rotations using density functional theory (DFT). Recent developments have shown that DFT methods are now sufficiently robust for predicting ORD values of chiral molecules (Polavarapu, P. L. (2002) Chirality 14, 768-781). The nucleobases Sp1 and Sp2 exhibit experimentally measured CD and ORD spectra that are very close to those of the respective precursor nucleosides dSp1 and dSp2 in shape and sign. The first nucleoside stereoisomer (dSp1) to elute from a typical Hypercarb HPLC column has (-)-S, while the second (dSp2) has (+)-R absolute configuration. The R and S assignments are applicable to the amino tautomeric forms in each case.

Effects of Reactive Power on Photovoltaic Inverter Reliability and Lifetime (2019)

For predicting the reliability and lifetime of Photovoltaic (PV) inverters, thermal cycling is considered the most important stressors in the inverter system. To realize this, a detailed electrothermal model of the PV inverter was developed along with the controllers. The model was verified by developing an in-house inverter, which was placed inside a thermal chamber to verify the losses and temperature rise within the system at various temperatures. After the verification of the model, a reduced order model of the inverter was implemented which can translate the mission profile of ambient temperature and solar irradiance into load profile of junction temperatures of the switches. The estimated junction temperature data was used to identify the reliability indices and predict the useful lifetime of the inverter system. After developing the models to predict useful lifetime of the system, the impact of reactive power on the overall reliability of the system was studied. Experiments show that lifetime and reliability of the inverter decreases as the operating power factor decreases from unity. The results are presented and discussed here.

The further construction of the two‐dimensional database of common human proteins (1995)

The master two-dimensional gel database (D. Burggraf et al., Electrophoresis 1992, 13, 729-732) [1] of common human proteins has been expanded to include detailed protein characteristics. Human cellular proteins from 5 cell lines and different cell organelles representing various tissues (muscle, nervous, connective, epithelial blood) and germ layers (ectoderm, endoderm and mesoderm), were separated by two-dimensional gel electrophoresis (2-DE). According to a recently developed algorithm, master gels of these different cells were established by computer-aided image processing. An expanded map with protein-chemical information of the polypeptides common to all human cells is shown. The synthetic, common human protein-map represents 856 spots resolved with an accuracy of 4 cm/pI unit. The protein spots were characterized either by their isoelectric point, molecular mass, integrated intensity, background-corrected optical density, spot area, or cellular distribution. About 80 proteins were further characterized and identified by protein name, amino acid composition analysis, N-terminal sequencing, enzymatic digest and subsequent peptide sequencing. Additionally the proteins of the common human protein map were identified by Western blotting. Specific information regarding glycosylation and quantitation of expression levels after chemical, biological and mechanical stimulation is included in the database.

Adaptive Transmitter Optimization in Multiuser Multiantenna Systems: Theoretical Limits, Effect of Delays, and Performance Enhancements (2005)

The advances in programmable and reconfigurable radios have rendered feasible transmitter optimization schemes that can greatly improve the performance of multiple-antenna multiuser systems. Reconfigurable radio platforms are particularly suitable for implementation of transmitter optimization at the base station. We consider the downlink of a wireless system with multiple transmit antennas at the base station and a number of mobile terminals (i.e., users) each with a single receive antenna. Under an average transmit power constraint, we consider the maximum achievable sum data rates in the case of (1) zero-forcing (ZF) spatial prefilter, (2) modified zero-forcing (MZF) spatial prefilter, and (3) triangularization spatial prefilter coupled with dirty-paper coding (DPC) transmission scheme. We show that the triangularization with DPC approaches the closed-loop MIMO rates (upper bound) for higher SNRs. Further, the MZF solution performs very well for lower SNRs, while for higher SNRs, the rates for the ZF solution converge to the MZF rates. An important impediment that degrades the performance of such transmitter optimization schemes is the delay in channel state information (CSI). We characterize the fundamental limits of performance in the presence of delayed CSI and then propose performance enhancements using a linear MMSE predictor of the CSI that can be used in conjunction with transmitter optimization in multiple-antenna multiuser systems.

IgG Antibodies against SARS-CoV-2 Correlate with Days from Symptom Onset, Viral Load and IL-10 (2020)

The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has resulted in a pandemic of the respiratory disease coronavirus disease 2019 (COVID-19). Antibody testing is essential to identify persons exposed to the virus and potentially in predicting disease immunity. 183 COVID-19 patients (68 of whom required mechanical ventilation) and 41 controls were tested for plasma IgG, IgA and IgM against the SARS-CoV-2 S1, S2, receptor binding domain (RBD) and N proteins using the MILLIPLEX<sup>®</sup> SARS-CoV-2 Antigen Panel. Plasma cytokines were concurrently measured using the MILLIPLEX<sup>®</sup> MAP Human Cytokine/Chemokine/Growth Factor Panel A. As expected the 183 COVID-19 positive patients had high levels of IgG, IgA and IgM anti-SARS-CoV-2 antibodies against each of the viral proteins. Sensitivity of anti-S1 IgG increased from 60% to 93% one week after symptom onset. S1-IgG and S1-IgA had specificities of 98% compared to the 41 COVID-19 negative patients. The 68 ventilated COVID-19 positive patients had higher antibody levels than the 115 COVID-19 positive patients who were not ventilated. IgG antibody levels against S1 protein had the strongest positive correlation to days from symptom onset. There were no statistically significant differences in IgG, IgA and IgM antibodies against S1 based on age. We found that patients with the highest levels of anti-SARS-CoV-2 antibodies had the lowest viral load in the nasopharynx. Finally there was a correlation of high plasma IL-10 with low anti-SARS-CoV-2 antibodies. Anti-SARS-CoV-2 antibody levels, as measured by a novel antigen panel, increased within days after symptom onset, achieving > 90% sensitivity and specificity within one week, and were highest in patients who required mechanical ventilation. Antibody levels were inversely associated with viral load but did not differ as a function of age. The correlation of high IL-10 with low antibody response suggests a potentially suppressive role of this cytokine in the humoral immune response in COVID-19.
CampylobacterDNA Is Present in Circulating Myelomonocytic Cells of Healthy Persons and in Persons with Guillain‐Barré Syndrome (2002)

Campylobacter jejuni is the prime cause of foodborne bacterial gastroenteritis. An important complication of C. jejuni enteritis is Guillain-Barré syndrome (GBS), an immune-mediated disorder of the peripheral nerve. The presence of C. jejuni DNA in peripheral blood mononuclear cells (PBMC) of patients with GBS, patients with C. jejuni enteritis, and healthy subjects was studied. Two target genes, the flagellin and the ceuE genes, were used for polymerase chain reaction (PCR) identification of Campylobacter species in DNA extracted from PBMC. Approximately 30% of the healthy subjects and 50% of the patients with GBS had PBMC containing C. jejuni DNA as verified by Southern blot analysis or sequencing of the PCR products. Cell sorting revealed that Campylobacter DNA was present in CD14(+) and CD33(+) populations, indicating that cells from the myelomonocytic lineage are the Campylobacter DNA-carrying cells. These findings show that Campylobacter DNA is present in blood cells of healthy humans, although viable bacteria could not be demonstrated.

Chicken pox after pediatric liver transplantation (2005)

Previous case series have reported serious complications of chicken pox (CP) after pediatric liver transplantation (PLT), mainly due to visceral dissemination. The goal of our study was to determine the incidence, risk factors, and outcomes of CP after PLT. A case-control study of all CP infections in pediatric transplant recipients followed at our center from September 1993 to April 2004 was performed. Data were collected before and after infection and at the same time points in age-, gender-, and transplant year-matched controls. Potential risk factors prior to CP and adverse outcomes after infection were compared between cases and controls. Twenty (6.2%) developed CP at a median of 1.8 yr (0.6-4.8) after PLT. All CP infections were cutaneous, with no evidence of organ involvement. Twelve were hospitalized: 9 only to receive intravenous acyclovir and 3 stayed > or =2 weeks for other complications. Risk factors were not statistically different among cases and controls. Of the outcomes analyzed, cases were significantly more likely to develop non-CP infections within one year of CP than controls (Hazard Ratio = 12.6, 95% confidence interval = 3.1-51.7; P < 0.001). These infections were often bacterial and occurred long after CP infection. In conclusion, CP is uncommon after PLT and has a low likelihood of organ dissemination. No risk factors were identified. Some cases required prolonged hospitalizations. Close monitoring for the development of late bacterial infections is warranted.

Data Augmentation in Time and Doppler Frequency Domain for Radar-based Gesture Recognition (2022)

This paper presents novel data augmentation techniques for gesture recognition based on multistatic Doppler spectrograms. Contrary to intricate approaches such as generative models or simulations, the presented methods generate additional samples by manipulating data in time and Doppler frequency domain. Thus, they resemble well-known techniques from computer vision tasks, but produce physically plausible data. Moreover, based on a comprehensive dataset a thorough investigation of the impact of training data extent on cross-subject validation accuracy is conducted. It is demonstrated that accuracy tends to saturate with growing training sets, and that the techniques presented in this work can help to reach the accuracy at saturation with only half the number of measurements.
