Autologous fat grafting in breast cancer patients (2012)

In the frame of the debate on the oncological safety of autologous fat grafting in breast reconstruction, we comment on the Personal View article recently appeared on The Breast by Lohsiriwat and colleagues (Breast 2011; 20:351–357), which reports a literature analysis, questioning the safety of fat grafting in patients with breast cancer. When mentioning the work by Rigotti et al. (Aesth Plast Surg 2010; 34:475), Authors claim that the methodology “should be criticized, because the risk of LRR (Late Relapse Rate) decreases with time and cannot be considered as equivalent in the pre and post lipofilling period”. This bias exists and was discussed for the dependent-group analysis reported in that paper; conversely, Authors lack mentioning that comparable relapse-free survival probabilities were found (log-rank test = 1.69; p = 0.19) in the frame of an independent–group analysis, designed to compare LRR in the period from surgery to first fat grafting session (Period I) in a group of patients, with LRR in the period starting from first fat grafting session, in average 20 months after surgery, of a second independent patient cohort. This result was confirmed (log-rank test = 1.27; p = 0.26) also when taking out from Period I the first 20 months after surgery, in order to avoid any possible bias on LR risk equivalence. In addition, Authors criticize the exclusion from the study of 104 breast conservative treatment patients, proving to have overlooked the reported patient inclusion criteria, according to which only 13 breast conservative treatment patients could have been enrolled in the study and were excluded due to evident statistical unbalance. Authors declare no conflicts of interest.
Detection of Australia Antigen in Various Fractions of Frozen Blood (1971)

Viral hepatitis has not been reported following transfusion with frozen blood. Seven such samples from donors positive for Australia (Au/SH) antigen were studied. After thawing, Au/SH antigen was found in five of seven discarded wash solutions and in only one of the seven supernatant reconstituting saline solutions which form part of the transfused product. The positive sample came from a patient who had the highest titer of Au/SH antigen in his serum. The freeze-thaw processing appears to dilute out serum hepatitis and the associated Au/SH antigen, so that overt hepatitis does not follow administration of frozen blood.
GaN PNP light-emitting bipolar junction transistor (2021)

Abstract An light-emitting bipolar transistor (LEBJT) has been developed in response to aspirations for on-chip electronics with GaN-based light-emitting diode (LED) devices. The design utilizes the existing p-n junction of an LED structure to construct a PNP bipolar junction transistor comprising two back-to-back p-n junctions, saving the need for customized structures or epitaxial regrowth. Two designs of monolithic GaN LEBJTs have been demonstrated in this work—an LEBJT with a larger emitter area size for conversion of electronic to optical signal, as well as an LEBJT with reduced emitter area for boosting of current gain. Employing an emitter comprising an array of nanopillars patterned by nanosphere lithography, the LEBJT exhibits an average current gain of 20 and a bandwidth of 180 MHz.
Service water quality monitor including hue and coloration grade (1998)

The authors introduce an index of coloration grade for evaluation of service water colour. The principle of the coloration grade measurement has been derived from authors' modification of the Tristimulus Filter Method of AWWA 1992 and JWWA 1993 Standard Method, and it has the advantage of applicability to all colours in the visible range. The characteristics of the hue and coloration grade measurement has been tested in the laboratory using various coloured samples obtained from water service pipes or an aqueduct. Compared with the “colour” measured by the platinum-cobalt method, the coloration grade is more sensitive to various water coloration and close to human senses.

Applying the above stated device, a Service Water Quality Monitor was newly developed and successfully tested at several distinctive fields. It monitors three items, colour, turbidity and residual chlorine which are obligatory in Japan to be daily examined at appropriate house taps. For the field test of about six months without any manual calibration, the accuracy of the hue and the coloration grade has shown maximum deviation of only 2.5% FS compared with the measurement by means of the standard solutions once a month.
III-nitride integration on ferroelectric materials of lithium niobate by molecular beam epitaxy (2005)

Integration of III-nitride electrical devices on the ferroelectric material lithium niobate (LiNbO3) has been demonstrated. As a ferroelectric material, lithium niobate has a polarization which may provide excellent control of the polarity of III-nitrides. However, while high temperature, 1000°C, thermal treatments produce atomically smooth surfaces, improving adhesion of GaN epitaxial layers on lithium niobate, repolarization of the substrate in local domains occurs. These effects result in multi domains of mixed polarization in LiNbO3, producing inversion domains in subsequent GaN epilayers. However, it is found that AlN buffer layers suppress inversion domains of III-nitrides. Therefore, two-dimensional electron gases in AlGaN∕GaN heterojunction structures are obtained. Herein, the demonstration of the monolithic integration of high power devices with ferroelectric materials presents possibilities to control LiNbO3 modulators on compact optoelectronic/electronic chips.
Recent progress of AlInGaN laser diodes (2005)

Nine years has passed since the initial development of GaN-based violet laser diodes (LDs) in the 405 nm wavelength range in 1995. Starting with next-generation high-density optical discs, the commercial use of violet LDs has been adopted in many new fields, such as biomedical, reprographic, and exposure fields. Recently, lasing wavelength has broadened to cover from the ultraviolet (UV) to blue-green regions, which enabled other new applications. In this paper, the current status of GaN-based LDs from the UV to blue-green regions is reported.
Pressure-stabilized divalent ozonide CaO3 and its impact on Earth’s oxygen cycles (2020)

High pressure can drastically alter chemical bonding and produce exotic compounds that defy conventional wisdom. Especially significant are compounds pertaining to oxygen cycles inside Earth, which hold key to understanding major geological events that impact the environment essential to life on Earth. Here we report the discovery of pressure-stabilized divalent ozonide CaO<sub>3</sub> crystal that exhibits intriguing bonding and oxidation states with profound geological implications. Our computational study identifies a crystalline phase of CaO<sub>3</sub> by reaction of CaO and O<sub>2</sub> at high pressure and high temperature conditions; ensuing experiments synthesize this rare compound under compression in a diamond anvil cell with laser heating. High-pressure x-ray diffraction data show that CaO<sub>3</sub> crystal forms at 35 GPa and persists down to 20 GPa on decompression. Analysis of charge states reveals a formal oxidation state of -2 for ozone anions in CaO<sub>3</sub>. These findings unravel the ozonide chemistry at high pressure and offer insights for elucidating prominent seismic anomalies and oxygen cycles in Earth's interior. We further predict multiple reactions producing CaO<sub>3</sub> by geologically abundant mineral precursors at various depths in Earth's mantle.
Analyzing birefringence in the retinal nerve fiber layer of diabetic patients using polarization sensitive OCT (2020)

Diabetes is a chronic metabolic disease characterized by elevated levels of blood glucose. Over time, it can lead to serious damages in the body. In the eyes, diabetic retinopathy (DR), the most common microvascular complication of diabetes, is a major cause of blindness. OCT can be used to provide high resolution images of the damages in the retina and follow their evolution over time. It is however still unclear which of the vascular or neurologic changes happen first in the development of the disease. In this work, we investigate the birefringence of the retinal nerve fiber layer (RNFL) of diabetic patients (with different stage of DR or no DR) and compare these results to healthy subject’s data. We use a PS-OCT system with an integrated retinal tracker for imaging (center wavelength of 860 nm, A-scan rate of 70 kHz). For each eye imaged, a raster scan centered on the optic nerve head (ONH) and a circular scan around the ONH (radius: 1.5mm) are taken. Considering only areas with a RNFL thickness &gt;100 &mu;m, birefringence values are calculated from an averaged circular tomogram for each eye. We observe a statistically significant reduced birefringence of the RNFL in the diabetic patients compared to the healthy volunteers.

Characterization of an infective molecular clone of the B-tropic, ecotropic BL/Ka(B) murine retrovirus genome (1982)

Using molecular cloning techniques, we amplified the unintegrated, linear proviral DNA of the BL/Ka(B) virus, a non-leukemogenic retrovirus of mouse strain C57BL/Ka. Two independent clones in lambda phage vector 607 and one subclone in pBR322 were infective when transfected into mouse fibroblasts. Analysis of the progeny virus revealed biological properties and a restriction map identical to those of the parental viral shock. Comparison of the restriction map with the maps of other ecotropic murine viruses reveals many similarities. Particularly interesting is the comparison of the N-tropic Akv virus and the B-tropic BL/Ka(B) virus. The long terminal repeats of the two viruses are virtually identical, as are 22 of 23 restriction sites located outside of the region which spans from 1.8 to 3.8 kilobases from the left end of the genome. Within this region, however, only three of nine sites examined are shared. This suggests that the BL/Ka(B) virus was derived from an endogenous N-tropic virus closely related to Akv by recombinational events which altered the sequence in the last half of the gag gene and the first third of the pol gene. This change is probably responsible for the observed difference in the Fv-1 tropism of the two viruses.

IC for motion-compensated de-interlacing, noise reduction, and picture-rate conversion (1999)

An IC for consumer television applies motion estimation and compensation for high quality video format conversion. The chip achieves perfect motion portrayal for all sources including 24, 25, and 30 Hz film material, and many display formats. The true-motion vectors are estimated with a sub-pixel resolution and are used to optimally de-interlace video broadcast signals, perform a motion compensated picture rate conversion and improve temporal noise reduction.
Antenna design for smartphones using modal/Eigenmode analysis (2017)

Practical Antenna Design for handheld devices is demonstrated through the utilization of the modal/Eigenmode theory of antennas. Here, a review of the underlying design fundamentals is outlined. Next, a design example featuring the antenna design of a modern smartphone is presented. The design cycle is simplified through finding an antenna with appropriate complex resonance frequency to cover a required band. Locating the appropriate feed position is then a matter of extracting the corresponding impedance map for this antenna.
Editorial Commentary: Belt and Suspenders—Linked Single‐Row Rotator Cuff Repair (2017)

Rotator cuff repairs fail at the suture-soft tissue interface. The linked single-row repair technique may provide increased soft tissue pullout strength, but further study is needed.
Experimental Eye Infections Caused by Pseudomonas aeruginosa (1976)

Cells of Pseudomonas aeruginosa were titered (1.0× 104–1.0× 108 cells) to determine the minimum number required to initiate corneal infection in Swiss-Webster and BALB/c mice. No infection was produced in either strain of mouse by direct application of the organisms to unwounded corneas. However, wounding the cornea in either strain followed by application of the bacteria (1 × 107–1 × 108 cells) produced corneal infection within 18–24 h. In Swiss-Webster mice, corneal morphology appeared normal within 4–6 weeks. However, in BALB/c mice, changes occurred by 12–15 days post-infection resulting in micro-ophthalmia. The results suggest development of an experimental model to comparatively study the natural immune mechanism of the eye to bacterial challenge.
Athermal Microwave Photonic Sensor Based on Single Microring Resonance Assisted by Machine Learning (2022)

We propose a machine learning (ML) assisted athermal microwave photonic (MWP) sensing scheme with high resolution based on a single microring resonance. The immunity of temperature interference of the high-resolution sensing is achieved by employing MWP sideband processing based interrogation, and supervised machine learning based on support vector regression (SVR) and neural tangent kernel (NTK) that are effective on small datasets. The MWP sideband processing transforms the variation of the target measurand into the shift of an ultra-deep notch in the radio frequency (RF) spectrum relieving the fabrication requirements on the microresonators, while ML accurately predicts the measurand by using the modulator bias voltage or RF passband transmission together with the RF notch position. The proposed sensor is demonstrated for relative humidity (RH) measurements using a silicon-on-insulator microring coated with polymethyl methacrylate. About 50 dB high RF rejection ratio is achieved over the sensing process, indicating a high sensing resolution. Despite the small experimental datasets, the established SVR and NTK models consistently exhibit lower mean absolute errors (MAEs) than the linear regression model in the RH prediction in the presence of temperature drifts. The NTK models achieve the lowest MAEs of 1.01% RH and 1.03% RH when the RF passband transmission and modulator bias are selected as the model input, respectively. The equivalent performances of the RF passband transmission and modulator bias voltage further demonstrate the feasibility of athermal sensing based solely on the MWP interrogation results of a single microring resonance, which simplifies the design and reduces the complexity.

ACNet: Strengthening the Kernel Skeletons for Powerful CNN via Asymmetric Convolution Blocks (2019)

As designing appropriate Convolutional Neural Network (CNN) architecture in the context of a given application usually involves heavy human works or numerous GPU hours, the research community is soliciting the architecture-neutral CNN structures, which can be easily plugged into multiple mature architectures to improve the performance on our real-world applications. We propose Asymmetric Convolution Block (ACB), an architecture-neutral structure as a CNN building block, which uses 1D asymmetric convolutions to strengthen the square convolution kernels. For an off-the-shelf architecture, we replace the standard square-kernel convolutional layers with ACBs to construct an Asymmetric Convolutional Network (ACNet), which can be trained to reach a higher level of accuracy. After training, we equivalently convert the ACNet into the same original architecture, thus requiring no extra computations anymore. We have observed that ACNet can improve the performance of various models on CIFAR and ImageNet by a clear margin. Through further experiments, we attribute the effectiveness of ACB to its capability of enhancing the model's robustness to rotational distortions and strengthening the central skeleton parts of square convolution kernels.
TUMOR BED RADIOSURGERY AFTER RESECTION OF CEREBRAL METASTASES (2008)

Tumor bed radiosurgery provides effective local control of the tumor after resection in most patients. These preliminary data support radiosurgery after resection rather than traditional radiation therapy.
In vivo imaging of ocular blood flow using high-speed ultrasound (2016)

Clinical ophthalmic ultrasound is currently performed with mechanically scanned, single-element probes, but these are unable to provide useful information about blood flow with Doppler techniques. Linear arrays are well-suited for the detection of blood flow, but commercial systems generally exceed FDA ophthalmic safety limits. A high-speed plane-wave ultrasound approach with an 18-MHz linear array was utilized to characterize blood flow in the orbit and choroid. Acoustic intensity was measured and the plane-wave mode was within FDA limits. Data were acquired for up to 2 sec and up to 20,000 frames/s with sets of steered plane-wave transmissions that spanned 2*<i>θ</i> degrees where 0 degrees was normal to the array. Lateral resolution was characterized using compounding from 1 to 50 transmissions and -6-dB lateral beamwidths ranged from 320 to 180 <i>μ</i>m, respectively. Compounded high-frame-rate data were post-processed using a singular value decomposition spatiotemporal filter and then flow was estimated at each pixel using standard Doppler processing methods. A 1-cm diameter rotating scattering phantom and a 2-mm diameter tube with a flow of blood-mimicking fluid were utilized to validate the flow-estimation algorithms. <i>In vivo</i> data were obtained from the posterior pole of the human eye which revealed regions of flow in the choroid and major orbital vessels supplying the eye.
Spatial effects of an electrically generated plasma on the interior ballistics of electrothermal-chemical (ETC) guns (1995)

Electrothermal-chemical (ETC) guns offer the prospect of significantly increased muzzle kinetic energy over conventional solid propellant gun systems as evidenced by experimental data collected over the past several years. To support the various experimental programs, codes developed specifically for ETC interior ballistic processes have matured including 0D, 1D, and 2D/3D models. Although these models in general have been successfully applied to simulate experimental data, prediction of gun interior ballistic performance at high gun energies has been more difficult. In this paper we examine comparisons of 0D and 1D model results with experimental data in order to gain a clearer understanding of the way that electrothermal energy input modifies the interior ballistics in ETC guns. These comparisons suggest that both axial and radial effects must be considered, necessitating development of first-principles 2D/3D models. Results from one such model, CRAFT, are presented in the paper.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
