6TiSCH++ with Bluetooth 5 and Concurrent Transmissions (2020)

Targeting dependable communications for industrial Internet of Things applications, IETF 6TiSCH provides mechanisms for efficient scheduling, routing, and forwarding of IPv6 traffic across low-power mesh networks. Yet, despite an overwhelming body of literature covering both centralized and distributed scheduling schemes for 6TiSCH, an effective control solution for large-scale multi-hop mesh networks remains an open challenge. This paper addresses this with a novel approach that eliminates much of the routing and link-layer overhead incurred by centralized schedulers, and provides a robust mechanism for data dissemination synchronization within 6TiSCH. Specifically, we leverage the physical layer (PHY) switching capabilities of modern low-power wireless platforms to build on recent work demonstrating the viability of Concurrent Transmission (CT)-based flooding protocols across the Bluetooth 5 (BT 5) PHYs. By switching the PHY and MAC layer at runtime, we inject a BT 5-based CT flood within a standard IEEE 802.15.4 TSCH slotframe, thereby providing a reliable, low-latency scheme for 6TiSCH control messaging. We present an analytical model and experimental evaluation showing how our solution not only exploits the BT 5 high data-rate PHY layers for rapid data dissemination, but can also provide reliable 6TiSCH association and synchronization even under external radio interference. We further discuss how the proposed technique can be used to address other open challenges within the standard.
Application of structured light imaging for high resolution mapping of underwater archaeological sites (2010)

This paper presents results from recent work using structured light laser profile imaging to create high resolution bathymetric maps of underwater archaeological sites. Documenting the texture and structure of submerged sites is a difficult task and many applicable acoustic and photographic mapping techniques have recently emerged. This effort was completed to evaluate laser profile imaging in comparison to stereo imaging and high frequency multibeam mapping. A ROV mounted camera and inclined 532 nm sheet laser were used to create profiles of the bottom that were then merged into maps using platform navigation data. These initial results show very promising resolution in comparison to multibeam and stereo reconstructions, particularly in low contrast scenes. At the test sites shown here there were no significant complications related to scattering or attenuation of the laser sheet by the water. The resulting terrain was gridded at 0.25 cm and shows overall centimeter level definition. The largest source of error was related to the calibration of the laser and camera geometry. Results from three small areas show the highest resolution 3D models of a submerged archaeological site to date and demonstrate that laser imaging will be a viable method for accurate three dimensional site mapping and documentation.
The Lateral Inframammary Fold Incision for Nipple-Sparing Mastectomy: Outcomes from Over 50 Immediate Implant-Based Breast Reconstructions (2012)

Nipple-sparing mastectomy (NSM) as a therapeutic or prophylactic procedure for breast cancer is rapidly gaining popularity as the literature continues to support it safety. The lateral inframammary fold (IMF) approach provides adequate exposure and eliminates visible scars on the anterior surface of the breast, making this incision cosmetically superior to radial or periareolar approaches. We reviewed 55 consecutive NSMs performed through a lateral IMF incision with immediate implant-based reconstruction, with or without tissue expansion, between June 2008 and June 2011. Prior to incision, breasts were lightly infiltrated with dilute anesthetic solution with epinephrine. Sharp dissection, rather than electrocautery, was used as much as possible to minimize thermal injury to the mastectomy flap. When indicated, acellular dermal matrix was placed as an inferolateral sling. Subsequent fat grafting to correct contour deformities was performed in select patients. Three-dimensional (3D) photographs assessed changes in volume, antero-posterior projection, and ptosis. Mean patient age was 46 years, and mean follow-up time was 12 months. Twelve mastectomies (22%) were therapeutic, and the remaining 43 (78%) were prophylactic. Seven of the nine sentinel lymph node biopsies (including one axillary dissection) (78%) were performed through the lateral IMF incision without the need for a counter-incision. Acellular dermal matrix was used in 34 (62%) breasts. Average permanent implant volume was 416 cc (range 176-750 cc), and average fat grafting volume was 86 cc (range 10-177 cc). In one patient a positive intraoperative subareolar biopsy necessitated resection of the nipple-areola complex (NAC), and in two other patients NAC resection was performed at a subsequent procedure based on the final pathology report. Mastectomy flap necrosis, requiring operative debridement, occurred in two breasts (4%), both in the same patient. One of these breasts required a salvage latissimus dorsi myocutaneous flap to complete the reconstruction. Three nipples (6%) required office debridement for partial necrosis and operative reconstruction later. No patient had complete nipple necrosis. No statistically significant differences existed between therapeutic and prophylactic mastectomies for developing partial skin and/or nipple necrosis (p = 0.35). Three episodes (5%) of cellulitis occurred, which responded to antibiotics without the need for explantation. Morphological outcomes using 3D scan measurements showed reconstructed breasts were larger, more projected, and less ptotic than the preoperative breasts (196 versus 248 cc, 80 versus 90 mm, 146 versus 134 mm, p < 0.01 for each parameter). Excellent results can be achieved with immediate implant-based reconstruction of NSM through a lateral IMF incision. NAC survival is reliable, and complication rates are low.
Effects of body orientation and rotation axis on pitch visual-vestibular interaction (1999)

Spatial transformations of the vestibular-optokinetic system must account for changes in head position with respect to gravity in order to produce compensatory oculomotor responses. The purpose of this experiment was to study the influence of gravity on the vestibulo-ocular reflex (VOR) in darkness and on visual-vestibular interaction in the pitch plane in human subjects using two different comparisons: (1) Earth-horizontal axis (EHA) rotation about an upright versus a supine body orientation, and (2) Earth-horizontal versus Earth-vertical (EVA) rotation axes. Visual-vestibular responses (VVR) were evaluated by measuring the slow phase velocity of nystagmus induced during sinusoidal motion of the body in the pitch plane (at 0.2 Hz and 0.8 Hz) combined with a constant-velocity vertical optokinetic stimulation (at +/- 36 degrees/s). The results showed no significant effect on the gain or phase of the VOR in darkness or on the VVR responses at 0.8 Hz between EHA upright and EHA supine body orientations. However, there was a downward shift in the VOR bias in darkness in the supine orientation. There were systematic changes in VOR and VVR between EHA and EVA for 0.2 Hz, including a reduced modulation gain, increased phase lead, and decreased bias during EVA rotation. The same trend was also observed at 0.8 Hz, but at a lesser extent, presumably due to the effects of eccentric rotation in our EVA condition and/or to the different canal input across frequencies. The change in the bias at 0.2 Hz between rotation in darkness and rotation with an optokinetic stimulus was greater than the optokinetic responses without rotation. During EHA, changes in head position relative to gravity preserve graviceptor input to the VVR regardless of body orientation. However, the modifications in VVR gain and phase when the rotation axis is aligned with gravity indicate that this graviceptive information is important for providing compensatory eye movements during visual-vestibular interaction in the pitch plane.
Connectionist Viterbi training: a new hybrid method for continuous speech recognition (2002)

A hybrid method for continuous-speech recognition which combines hidden Markov models (HMMs) and a connectionist technique called connectionist Viterbi training (CVT) is presented. CVT can be run iteratively and can be applied to large-vocabulary recognition tasks. Successful completion of training the connectionist component of the system, despite the large network size and volume of training data, depends largely on several measures taken to reduce learning time. The system is trained and tested on the TI/NBS speaker-independent continuous-digits database. Performance on test data for unknown-length strings is 98.5% word accuracy and 95.0% string accuracy. Several improvements to the current system are expected to increase these accuracies significantly.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Using Conducting Wire at A-Sandwich Junctions to Improve the Transmission Performance of Radomes (2008)

We present design procedures for using conducting wires in A-sandwich junctions to achieve high transmission performance; benchtest results validate the procedures. The scattering characteristics of the junction are obtained by solving the electric field integral equation of volumetric equivalent currents. The transmission performance is evaluated by subtracting the scattered fields of the same-sized A-sandwich panel in order to offset the effect of edge diffraction. Optimum wire width is determined by examining transmission performance with different arrangements. The designed junction achieves high transmission performance. The measured scattering characteristics of a bench model demonstrate the validity of the presented method.
Commentary (1995)

In the author's view the striking changes which heterosexual relationships are currently undergoing in Western industrial societies are being brought about by a marked shift in gender relations and gender discourse. Two tendencies are particularly noticeable: (1) sexual morals are being replaced by interaction morals or morals of negotiating, hinging on the assumption that sexual behavior should be mutually agreed upon and ratified; and (2) heterosexual relationships are gradually becoming desexualised, in apparent contrast to the sexualisation of almost every aspect of the world around us.
Quantum limits of the hyper-Rayleigh scattering susceptibility (2001)

Sum rules have been used to show that there is an upper limit to molecular susceptibilities. Such calculations have been applied to the diagonal part of the second-order susceptibility tensor as measured with electric-field-induced second-harmonic generation, and to a variety of third-order measurements. The results show that the off-resonant susceptibilities of all molecules measured fall within the calculated limits. In this contribution, we show that the most susceptibilities measured with hyper Rayleigh scattering (HRS) fall below the two-dimensional theoretical limit, and discuss the issue of why some molecules appear to break this limit.
Investigation of Coaxial Rotor Performance for a Gun-launched Micro Air Vehicle (2023)

This paper presents an experimental parametric study to maximize the hover efficiency of a coaxial rotor system for a micro air vehicle (MAV) that could be launched from a 40 mm grenade launcher. Towards this, isolated rotor experiments were first conducted to optimize the performance of a single rotor at low Reynolds numbers (Re) through varying parameters including blade pitch angle, thickness-to-chord ratio (t/c), chord length, and Reynolds number. Results showed that t/c had minimal impact on the figure of merit FM) below 4%, while increasing blade chord length significantly improved hover efficiency until a chord length of 16.6 mm (solidity = 0.10). The optimal pitch angle for the isolated rotor was around 16 degrees, and the maximum FM was 0.59 at Re = 70,000. Coaxial rotor experiments were performed using the optimal isolated rotor as the baseline. The vertical separation between the upper and lower rotors had negligible impact on performance for a separation distance range from 0.5R to 3R. However, below a separation distance of 0.5R, the thrust and FM of the lower rotor increased and that of the upper rotor decreased. The highest FM obtained for the coaxial rotor was around 0.60 at Re = 30,000, which remained relatively constant across all vertical separations tested. The coaxial rotor system produced almost 1.66 times the thrust of an isolated single rotor. When compared at the same disk loading, the power loading (thrust/power) for the coaxial rotor was similar to that of an isolated single rotor. A comprehensive analysis (RCAS) was used to model the MAV-scale isolated rotor in hover and the analytical predictions agreed well with the experiments. In order to generate the airfoil lookup table for the RCAS model, water tunnel experiments were conducted at Re = 44,000 using a scaled-up wing with the exact same circular-cambered plate airfoil used in the coaxial rotor blades.

One-Pot Synthesis of High-Capacity Silicon-Lithium Anodes via On-Copper Growth of a Semi-Conducting, Porous Polymer (2021)

Silicon-based anodes with lithium ions as charge carriers have the highest predicted charge density of 3579 mA h g-1 (for Li15Si4) while being comparatively safe. Contemporary electrodes do not achieve these theoretical values largely because production paradigms remained unchanged since their inception and rely on the mixing of weakly coordinated, multiple components. In this paper, we present the one-pot synthesis of high-performance anodes that reach the theoretical capacity of the fully lithiated state of silicon. Here, a semi-conductive triazine-based graphdiyne polymer network is grown around silicon nanoparticles directly on the current collector, a copper sheet. The current collector (Cu) acts as the catalyst for the formation of a semi-conductive triazine-based graphdiyne polymer network that grows around the inorganic, active material (Si). In comparison to established electrode assemblies, this process (i) omits any steps related to curing, drying, and annealing, (ii) does away with binders and conductivity-enhancing additives that decrease volumetric and gravimetric capacity, and (iii) cancels out the detrimental effects on performance, chemical and physical stability of conventional, three-component anodes (Si, binder, carbon black). This is because, the porous, semi-conducting organic framework (i) adheres to the current collector on which it grows via cooperative van der Waals interactions, (ii) acts effectively as conductor for electrical charges and binder of silicon nanoparticles via conjugated, covalent bonds, and (iii) enables selective transport of mass and charge-carriers (electrolyte and Li-ions) through pores of defined size. As a result, the anode shows extraordinarily high capacity at the theoretical limit of fully lithiated silicon, excellent performances in terms of cycling (exceeding 70% capacity retention after 100 cycles), and high mechanical and thermal stability. These high-performance anodes pave the way for use in flexible, wearable electronics and in environmentally demanding applications.
[Effects of active and passive smoking during pregnancy on the blood flow in uterine artery in third trimester of pregnancy]. (2015)

The aim of the study was to evaluate the influence of active and passive maternal tobacco smoking on the parameters of blood flow in the uterine arteries in the third trimester. of pregnancy. The study was performed among 96 pregnant women in a single full-term pregnancy in the third trimester of pregnancy. A questionnaire assessing the status of the concentration of nicotine and nicotine metaboliteotinine in the serum of pregnant. The plasma was extracted technique of liquid-liquid, and then performed laboratory assays using high performance liquid chromatography with spectrophotometric detection using norepinephrine as an internal standard. Based on the concentration of cotinine and interview patients were assigned to three groups: Group 1--patients smoking cigarettes during the entire pregnancy (23), group 2--patients exposed to environmental tobacco smoking (30) and a control group 3--nonsmokers and patients unexposed to passive smoking (43). In the third trimester of pregnancy blood flow in the uterine arteries was performed using "B-mode" technique with function of spectral Doppler. We analized the pulsatility index and resistance index in both uterine arteries, the presence of the indent diastolic "notch" and the scale of the uterine arteries. There were no statistically significant differences with regards to pulsatility index and index of resistance in blood flow in the uterine arteries in different groups of patients. The presence of the indent diastolic "notch" was significantly more frequent among active smokers, compared to women passively exposed to tobacco smoke and non-smoking women (39.1% vs. 20% vs. 4.6%; p = 0.012). The values in the scale of uterine arteries showed no significant difference between groups. Both active and passive smoking had no significant effect on the blood flow in uterine artery in pregnant women in the third trimester of pregnancy.
Microphone array design for spatial audioobject early reflection parametrisation fromroom impulse responses (2017)

Room Impulse Responses (RIRs) measured with microphone arrays capture spatial and nonspatial
information, e.g. the early reflections’ directions and times of arrival, the size of the
room and its absorption properties. The Reverberant Spatial Audio Object (RSAO) was proposed
as a method to encode room acoustic parameters from measured array RIRs. As the RSAO is
object-based audio compatible, its parameters can be rendered to arbitrary reproduction systems
and edited to modify the reverberation characteristics, to improve the user experience. Various
microphone array designs have been proposed for sound field and room acoustic analysis, but a
comparative performance evaluation is not available. This study assesses the performance of five
regular microphone array geometries (linear, rectangular, circular, dual-circular and spherical) to
capture RSAO parameters for the direct sound and early reflections of RIRs. The image source
method is used to synthesise RIRs at the microphone positions as well as at the centre of the array.
From the array RIRs, the RSAO parameters are estimated and compared to the reference parameters
at the centre of the array. A performance comparison among the five arrays is established
as well as the effect of a rigid spherical baffle for the circular and spherical arrays. The effects
of measurement uncertainties, such as microphone misplacement and sensor noise errors, are also
studied. The results show that planar arrays achieve the most accurate horizontal localisation
whereas the spherical arrays perform best in elevation. Arrays with smaller apertures achieve a
higher number of detected reflections, which becomes more significant for the smaller room with
higher reflection density.

Predictors of effects and adverse effects of pirfenidone on idiopathic pulmonary fibrosis (2012)

Introduction: Idiopathic pulmonary fibrosis (IPF) is a poor prognostic fibrotic lung disease with unknown etiologies. Pirfenidone (PFD) was recently reported to decrease the rate of decline in vital capacity and it is anticipated that PFD improves prognosis of IPF patients. Aim: We prospectively examined clinical findings of IPF to predict the effects and adverse effects of PFD. Subjects: PFD was administered to 41 cases of IPF between January 2009 and December 2010. Severity stage (I/II/III/IV) of IPF defined by Japanese Respiratory Society (JRS) were 9/6/9/17, respectively. PFD was discontinued within 3 months because of adverse effects or death in 11 cases. Effects of PFD were evaluated by definition by JRS in 30 cases treated with PFD for more than 3 months. Adverse effects were evaluated in all cases. Method: Chi square test for univariate analysis and multivariate logistic regression analysis was performed using various clinical findings to clarify the predictor of short-term effects of PFD and its adverse effects, especially appetite loss and/or nausea. Results: Improvement after PFD therapy was observed in 6 cases (20%). Severity stage I/II and diagnosis of IPF based on surgical biopsy specimens were significant predictors of improvement by chi square test and multivariate analysis. Appetite loss and/or nausea occurred more in IPF patients with older age (>68 yrs) and without intake of proton-pomp inhibitor (PPI) by multivariate logistic regression analysis. Conclusions: Effects of PFD is better in IPF patients with severity stage I/II and/or diagnosed by histologically. Appetite loss and/or nausea significantly associated with older age and no PPI intake.
Crystal structures of complexes of vitamin D receptor ligand-binding domain with lithocholic acid derivatives (2013)

The secondary bile acid lithocholic acid (LCA) and its derivatives act as selective modulators of the vitamin D receptor (VDR), although their structures fundamentally differ from that of the natural hormone 1α,25-dihydroxyvitamin D3 [1,25(OH)2D3)]. Here, we have determined the crystal structures of the ligand-binding domain of rat VDR (VDR-LBD) in ternary complexes with a synthetic partial peptide of the coactivator MED1 (mediator of RNA polymerase II transcription subunit 1) and four ligands, LCA, 3-keto LCA, LCA acetate, and LCA propionate, with the goal of elucidating their agonistic mechanism. LCA and its derivatives bind to the same ligand-binding pocket (LBP) of VDR-LBD that 1,25(OH)2D3 binds to, but in the opposite orientation; their A-ring is positioned at the top of the LBP, whereas their acyclic tail is located at the bottom of the LBP. However, most of the hydrophobic and hydrophilic interactions observed in the complex with 1,25(OH)2D3 are reproduced in the complexes with LCA and its derivatives. Additional interactions between VDR-LBD and the C-3 substituents of the A-ring are also observed in the complexes with LCA and its derivatives. These may result in the observed difference in the potency among the LCA-type ligands.
