Electrical control of spins and giant g-factors in ring-like coupled quantum dots (2019)

Emerging theoretical concepts for quantum technologies have driven a continuous search for structures where a quantum state, such as spin, can be manipulated efficiently. Central to many concepts is the ability to control a system by electric and magnetic fields, relying on strong spin-orbit interaction and a large g-factor. Here, we present a mechanism for spin and orbital manipulation using small electric and magnetic fields. By hybridizing specific quantum dot states at two points inside InAs nanowires, nearly perfect quantum rings form. Large and highly anisotropic effective g-factors are observed, explained by a strong orbital contribution. Importantly, we find that the orbital contributions can be efficiently quenched by simply detuning the individual quantum dot levels with an electric field. In this way, we demonstrate not only control of the effective g-factor from 80 to almost 0 for the same charge state, but also electrostatic change of the ground state spin.
Clinical Assessment of Hip Instability in the Newborn by an Orthopedic Surgeon and a Pediatrician (1986)

The aim of this study was to improve the rate of detection of hip instability in the neonate. Over a period of 3 years, a pediatric orthopedic surgeon and a neonatal pediatrician both examined 12,891 neonates. During the fourth year, 5,087 newborns were examined by a pediatrician only. Each examiner, working independently, found that 51 babies had neonatal hip instability. In an additional 25 babies, one examiner failed to detect this instability on initial examination. Finally, 36 babies judged to have stable hips at birth later gave cause for orthopedic treatment. These findings strongly suggest that screening should not be restricted to the neonate but should involve several sequential examinations.
DESIGN AND TIME-DOMAIN ANALYSIS OF A HIGH-VOLTAGE IMPULSED TEST-BED FOR NEAR-FIELD THERMOACOUSTIC TOMOGRAPHY (2013)

We present numerical time-domain modeling and validation framework for impulse-driven near-field thermoacoustics imaging. It has been recently demonstrated that this new imaging approach comprises a viable alternative for high performance and low-cost imaging using the thermoacoustic phenomenon. Placement of the imaged object in a close vicinity (near field) of an antenna elements along with generation of ultrashort (nanosecond) duration high-voltage excitation impulses further provide high imaging resolution and ensure that sufficient level of electromagnetic energy reaches the object under investigation. In order to analyze the measured results and also provide a design and optimization framework, this work presents a full-wave computational electromagnetic framework which couples the near-field electromagnetic field to the acoustic signal generation. The numerical method comprises a finite integral time domain method (FITD) based on the industry standard CST 2010 software package. The results can be further utilized for normalization and quantification of the generated images.
Nanocomposite Foams of Polypropylene and Carbon Nanotubes: Preparation, Characterization, and Evaluation of their Performance as EMI Absorbers (2015)

Highly expanded nanocomposite foams of polypropylene and carbon nanotubes (PP/CNT) are formed using supercritical carbon dioxide (scCO 2 ) technology. The foaming parameters (temperature, pressure) are investigated to establish their influence on the morphology of the resulting foams and their impact on the electrical conductivity. As promising electromagnetic‐interference (EMI) absorbers, the EMI shielding performance of the foams is determined, and a preliminary relationship is established between foam morphology and the EMI shielding performance. The best candidates are highly expanded foams with a volume expansion of &gt;25, containing 0.1 vol% CNTs; they are able to absorb more than 90% of the incident radiation between 25 and 40 GHz. image
Edge Dithering for Robust Adaptive Graph Convolutional Networks (2019)

Graph convolutional networks (GCNs) are vulnerable to perturbations of the graph structure that are either random, or, adversarially designed. The perturbed links modify the graph neighborhoods, which critically affects the performance of GCNs in semi-supervised learning (SSL) tasks. Aiming at robustifying GCNs conditioned on the perturbed graph, the present paper generates multiple auxiliary graphs, each having its binary 0-1 edge weights flip values with probabilities designed to enhance robustness. The resultant edge-dithered auxiliary graphs are leveraged by an adaptive (A)GCN that performs SSL. Robustness is enabled through learnable graph-combining weights along with suitable regularizers. Relative to GCN, the novel AGCN achieves markedly improved performance in tests with noisy inputs, graph perturbations, and state-of-the-art adversarial attacks. Further experiments with protein interaction networks showcase the competitive performance of AGCN for SSL over multiple graphs.

Sequencing the mosaic genome of Brahman cattle identifies historic and recent introgression including polled (2018)

Brahman cattle have a Bos indicus and Bos taurus mosaic genome, as a result of the process used to create the breed (repeat backcrossing of Bos taurus females to Bos indicus bulls). With the aim of identifying Bos taurus segments in the Brahman genome at sequence level resolution, we sequenced the genomes of 46 influential Brahman bulls. Using 36 million variants identified in the sequences, we searched for regions close to fixation for Bos indicus or Bos taurus segments that were longer than expected by chance (from simulation of the breed formation history of Brahman cattle). Regions close to fixation for Bos indicus content were enriched for protein synthesis genes, while regions of higher Bos taurus content included genes of the G-protein coupled receptor family (including genes implicated in puberty, such as THRS). The region with the most extreme Bos taurus enrichment was on chromosome 14 surrounding PLAG1. The introgressed Bos taurus allele at PLAG1 increases stature and the high frequency of the allele likely reflects strong selection for the trait. Finally, we provide evidence that the polled mutation in Brahmans, a desirable trait under very strong recent selection, is of Celtic origin and is introgressed from Bos taurus.

Quantitation of Alpha-Glucosidase Activity Using Fluorinated Carbohydrate Array and MALDI-TOF-MS (2016)

Quantitation of alpha-glucosidase (α-GD) activity is of significance to diagnosis of many diseases including Pompe disease and type II diabetes. We report here a new method to determine α-GD activity using matrix-assisted laser desorption/ionization (MALDI)-time-of-flight (TOF) mass spectrometry (MS) in combination with carbohydrate microarray and affinity surface chemistry. Carbohydrate probes are synthesized for capture of the enzymatic reaction products and the adducts are loaded onto a fluorinated gold surface to generate an array, which is followed by characterization by MALDI-TOF-MS. The ratio of intensities is used to determine the level of activity of several enzymes. In addition, half maximal inhibitory concentration (IC50) of acarbose and epigallocatechin gallate are also determined using this approach, and the results agree well with the reported values. This method is advantageous as compared to conventional colorimetric techniques that typically suffer matrix interference problems from samples. The use of the polyfluorinated surface has effectively suppressed the interference.
Four-legged three-phase PFC rectifier with fault tolerant capability (2002)

A four-legged three-phase PFC rectifier is proposed to handle unbalanced source voltage and to provide fault tolerant operation. The four-legged PFC rectifier is controlled by a three-dimensional space vector modulation (3D SVM) scheme, and runs in the overmodulation region when the source is unbalanced and/or a leg failure occurs. Modeling and control of the four-legged PFC rectifier are presented. Under unbalanced source, operation of the four-legged rectifier with three control strategies-equal current, equal resistance and constant power are analyzed. Two rectifier failure modes are studied: (1) entire leg fails; (2) active switches fail with the anti-parallel diodes still functional. It turns out that in both failure modes, the PFC rectifier can have an equal or higher than 2/3 of the rated output power level. The operation of the four-legged rectifier with 3D SVM is demonstrated by experimental results. The simulation results show that the proposed four-legged rectifier is advantageous over directly coupled three single-phase PFC rectifier and three-legged three-phase PFC rectifier.
CF-MAC and H-MAC Protocols for Energy Saving in Wireless Ad Hoc Networks (2005)

Wireless ad-hoc networks are widely adopted in contexts where a temporary network connectivity is required. The distributed and flexible architecture of these networks is a key strength but, due to the scarce energy resources available at each station, innovative energy efficient MAC algorithms are required in order to extend as much as possible network lifetime, while providing acceptable throughput and delays. Starting from the theory of balanced incomplete block design (BIBD), this paper proposes two power efficient MAC algorithms, which will be referred to as hybrid MAC (H-MAC) and collision free MAC (CF-MAC). The H-MAC algorithm combines standard IEEE 802.11 power saving features with a BIBD-based schedule. CF-MAC, instead, is a fully BIBD-based protocol, which allows a collision free transmission over a shared wireless medium. The performance of the proposed MAC schemes have been compared with the standard 802.11 power saving algorithm using computer simulations, showing that: (1) CF-MAC improves the overall network throughput and reduces the energy consumption with respect to the 802.11 power saving while guaranteeing acceptable delays; (2) H-MAC reduces the energy consumption with respect to 802.11 power saving while guaranteeing the same throughput, at the expense of higher delays.
Spastic paraplegia, optic atrophy, microcephaly with normal intelligence, and XY sex reversal: a new autosomal recessive syndrome? (1998)

Two female sibs of first cousin Iranian parents were found to have the syndrome of spastic paraplegia, optic atrophy with poor vision, microcephaly, and normal cognitive development. Karyotype analysis showed a normal female constitution in one and a male constitution (46,XY) in the other. The XY female showed normal female external genitalia, normal uterus and tubes, and streak gonads. SRY gene sequencing was normal. We conclude that the present family probably represents a new autosomal recessive trait of pleiotropic effects including XY sex reversal and adds further evidence for the heterogeneity of spastic paraplegia syndromes as well as sex reversal syndromes.
Axl receptor tyrosine kinase is a regulator of apolipoprotein E (2020)

Alzheimer's disease (AD), the leading cause of dementia, is a chronic neurodegenerative disease. Apolipoprotein E (apoE), which carries lipids in the brain in the form of lipoproteins, plays an undisputed role in AD pathophysiology. A high-throughput phenotypic screen was conducted using a CCF-STTG1 human astrocytoma cell line to identify small molecules that could upregulate apoE secretion. AZ7235, a previously discovered Axl kinase inhibitor, was identified to have robust apoE activity in brain microglia, astrocytes and pericytes. AZ7235 also increased expression of ATP-binding cassette protein A1 (ABCA1), which is involved in the lipidation and secretion of apoE. Moreover, AZ7235 did not exhibit Liver-X-Receptor (LXR) activity and stimulated apoE and ABCA1 expression in the absence of LXR. Target validation studies using AXL-/- CCF-STTG1 cells showed that Axl is required to mediate AZ7235 upregulation of apoE and ABCA1. Intriguingly, apoE expression and secretion was significantly attenuated in AXL-deficient CCF-STTG1 cells and reconstitution of Axl or kinase-dead Axl significantly restored apoE baseline levels, demonstrating that Axl also plays a role in maintaining apoE homeostasis in astrocytes independent of its kinase activity. Lastly, these effects may require human apoE regulatory sequences, as AZ7235 exhibited little stimulatory activity toward apoE and ABCA1 in primary murine glia derived from neonatal human APOE3 targeted-replacement mice. Collectively, we identified a small molecule that exhibits robust apoE and ABCA1 activity independent of the LXR pathway in human cells and elucidated a novel relationship between Axl and apoE homeostasis in human astrocytes.

Electronic states of intrinsic surface and bulk vacancies in FeS<sub>2</sub> (2012)

Understanding the stability and reactivity of iron sulfide phases is key to developing predictive capabilities for assessing their corrosion and catalytic activity. The differences between the free surface and the bulk interior of such phases are of particular importance in this context. Here, we employ density functional theory to investigate the formation energetics and electronic structure of intrinsic Fe and S vacancies in bulk pyrite (FeS(2)) and on the pyrite (100) surface. The formation energies of intrinsic bulk vacancies of all charge states are found to be high, ranging from 1.7 to 3.7 eV. While the formation energies of surface vacancies are lower, varying from 1.4 to 2.1 eV for S vacancies and from 0.3 to 1.7 eV for Fe vacancies, they are too large to result in significant sub-stoichiometry in bulk pyrite at moderate temperatures. On the basis of charged defect formation energies and defect equilibria calculations, intrinsic charge carriers are expected to outnumber point defects by several orders of magnitude, and therefore, pure pyrite is not expected to demonstrate p-type or n-type conductivity. The presence of surface states is observed to cause a reduction in the band gap at the (100) surface, which was captured computationally and experimentally using tunneling spectroscopy measurements in this work. The vacancy-induced defect states behave as acceptor-like or donor-like defect states within the bulk band gap. The findings on the stoichiometry and the electronic structure of active sites on the (100) surface have important implications for the reactivity of pyrite.
Unified Fourier-based Kernel and Nonlinearity Design for Equivariant Networks on Homogeneous Spaces (2022)

We introduce a unified framework for group equivariant networks on homogeneous spaces derived from a Fourier perspective. We consider tensor-valued feature fields, before and after a convolutional layer. We present a unified derivation of kernels via the Fourier domain by leveraging the sparsity of Fourier coefficients of the lifted feature fields. The sparsity emerges when the stabilizer subgroup of the homogeneous space is a compact Lie group. We further introduce a nonlinear activation, via an elementwise nonlinearity on the regular representation after lifting and projecting back to the field through an equivariant convolution. We show that other methods treating features as the Fourier coefficients in the stabilizer subgroup are special cases of our activation. Experiments on $SO(3)$ and $SE(3)$ show state-of-the-art performance in spherical vector field regression, point cloud classification, and molecular completion.
Patient Preferences for Attributes of Primary Surgical Debulking Versus Neoadjuvant Chemotherapy for Treatment of Newly Diagnosed Ovarian Cancer (2019)

(Abstracted from Cancer 2019;125:4399–4406) Retrospective analyses have found that optimal tumor debulking after a new diagnosis of ovarian cancer results in significantly greater progression-free survival (PFS) and overall survival (OS) compared with those who are suboptimally debulked. Primary debulking surgery (PDS) has become a common first line of therapy in patients with ovarian cancer.
Radioprotective Efficacy of Gamma-Tocotrienol in Nonhuman Primates (2016)

The search for treatments to counter potentially lethal radiation-induced injury over the past several decades has led to the development of multiple classes of radiation countermeasures. However, to date only granulocyte colony-stimulating factor (G-CSF; filgrastim, Neupogen)and pegylated G-CSF (pegfilgrastim, Neulasta) have been approved by the United States Food and Drug Administration (FDA) for the treatment of hematopoietic acute radiation syndrome (ARS). Gamma-tocotrienol (GT3) has demonstrated strong radioprotective efficacy in the mouse model, indicating the need for further evaluation in a large animal model. In this study, we evaluated GT3 pharmacokinetics (PK) and efficacy at different doses of cobalt-60 gamma radiation (0.6 Gy/min) using the nonhuman primate (NHP) model. The PK results demonstrated increased area under the curve with increasing drug dose and half-life of GT3. GT3 treatment resulted in reduced group mean neutropenia by 3-5 days and thrombocytopenia by 1-5 days. At 5.8 and 6.5 Gy total-body irradiation, GT3 treatment completely prevented thrombocytopenia. The capability of GT3 to reduce severity and duration of neutropenia and thrombocytopenia was dose dependent; 75 mg/kg treatment was more effective than 37.5 mg/kg treatment after a 5.8 Gy dose. However, the higher GT3 dose (75 mg/kg) was associated with higher frequency of adverse skin effects (small abscess) at the injection site. GT3 treatment of irradiated NHPs caused no significant difference in animal survival at 60 days postirradiation, however, low mortality was observed in irradiated, vehicle-treated groups as well. The data from this pilot study further elucidate the role and pharmacokinetics of GT3 in hematopoietic recovery after irradiation in a NHP model, and demonstrate the potential of GT3 as a promising radioprotector.
O-155. Expectancy of pregnancy and pregnancy outcome in couples undergoing homologous IUI in clomiphene citrate-stimulated cycles (1997)

unsuccessful, those who were undergoing IVF treatment at the time of completing the questionnaire and those who had been involved in fertility examinations and treatment for a longer period of time were less satisfied about the psychosocial guidance they received. The factors of age, sex and level of education, as well as the number of IVF attempts, appeared to influence contentment with only a few aspects of psychosocial guidance.
New pyrazolo[3,4-b]pyridones as selective A1 adenosine receptor antagonists: synthesis, biological evaluation and molecular modelling studies (2005)

A series of ethyl 4-amino-1-(2-chloro-2-phenylethyl)-6-oxo-6,7-dihydro-1H-pyrazolo[3,4-b]pyridine-5-carboxylates () has been synthesized as potential A(1) adenosine receptor (A(1) AR) ligands. Binding affinities of the new compounds were determined for adenosine A(1), A(2A) and A(3) receptors. Compounds and showed good affinity (K(i)= 299 nM and 517 nM, respectively) and selectivity towards A(1) AR, whereas showed good affinity for A(2A) AR (K(i)= 290 nM), higher than towards A(1) AR (K(i)= 1000 nM). The only arylamino derivative of the series displayed high affinity (K(i)= 4.6 nM) and selectivity for A(3) AR. Molecular modelling and 3D-QSAR (CoMFA) studies carried out on the most active compounds gave further support to the pharmacological results.
