The ecosphere of online service delivery and its growing presence in automobile sector: an extended study of connected technology in Indian outlook (2021)

The digitalisation, where everything rotates around the "e" ecosphere, digitalisation has spread its extensions over all the human life. The immense use of digital tools and technique, like online service delivery and its platforms that too in large numbers, one might add connected technology, that influences the Indian Automobile Industry, has seemed a genuine possibility. The data based on the responses of consumers of premium automobile companies i.e., Tata motors, BMW, Mercedes-Benz, and Ford shows that high-income group millennials from Delhi NCR are the primary users of connected technology-based automobiles. Further, SEM analysis results show that there is a significant role played by the online service delivery via connected technology on influencing the level of satisfaction.
Anisotropy in Thermal and Electronic Properties of Single Crystal GeSe2 Obtained by the Photoacoustic Method (1998)

Anisotropy in the thermal and electronic properties for two directions of a thermal wave propagation in GeSe 2 single crystal was investigated using the photoacoustic frequency transmission technique. First, the electric field of an incident polarized light beam was adjusted to be perpendicular to the “ c ” axis ( E l ⊥ c ), and then parallel to it ( E l // c ) . It is shown that there is an obvious difference in the PA amplitude and phase spectra of the same sample, for cases when E l // c and E l ⊥ c axis. The results for thermal diffusivity D T obtained by fitting procedure for these two orientations of the electric field with regard to the “ c ” axis, are calculated: D T// =1.1×10 -2 and D T⊥ =1.7×10 -3 cm 2 /s, e.g. their ratio is 6.6. The electronic transport parameters are also given: the carrier ambipolar diffusion coefficient D // =1.5 cm 2 /s and D ⊥ =2.5 cm 2 /s.
Ab‐initio‐Strukturbestimmung von Vaterit mit automatischer Beugungstomographie (2012)

„Das Mineral Vaterit ist Gegenstand umfangreicher Diskussionen“ ist eine typische Aussage, wie man sie in Lehrbüchern zur anorganischen Chemie findet. Das Polymorph des Calciumcarbonats hat eine Schlüsselrolle in Verwitterungs- und Biomineralisationsprozessen, liegt jedoch stets in für die Strukturaufklärung nicht geeigneten verwachsenen Nanokristallen vor. Nun gelang die Strukturaufklärung von Vaterit anhand eines nicht einmal 50 nm großen Kristalls mithilfe der Elektronenbeugungstomographie.

Short DNA Fragments Are a Hallmark of Heavy Charged-Particle Irradiation and May Underlie Their Greater Therapeutic Efficacy (2016)

Growing interest in proton and heavy ion therapy has reinvigorated research into the fundamental biological mechanisms underlying the therapeutic efficacy of charged-particle radiation. To improve our understanding of the greater biological effectiveness of high-LET radiations, we have investigated DNA double-strand breaks (DSBs) following exposure of plasmid DNA to low-LET Co-60 gamma photon and electron irradiation and to high-LET Beryllium and Argon ions with atomic force microscopy. The sizes of DNA fragments following radiation exposure were individually measured to construct fragment size distributions from which the DSB per DNA molecule and DSB spatial distributions were derived. We report that heavy charged particles induce a significantly larger proportion of short DNA fragments in irradiated DNA molecules, reflecting densely and clustered damage patterns of high-LET energy depositions. We attribute the enhanced short DNA fragmentation following high-LET radiations as an important determinant of the observed, enhanced biological effectiveness of high-LET irradiations.

Multiple RISs-Aided Networks: Performance Analysis and Optimization (2023)

This paper analyzes the performance of multiple reconfigurable intelligent surfaces (RISs)-aided networks with opportunistic RIS scheduling. The paper also provides some optimization results on the number of reflecting elements on RISs and the optimal placement of RISs. We first derive accurate closed-form approximations for RIS channels' distributions assuming independent non-identically distributed (i.ni.d.) Nakagami- <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">m</i> fading environment. Then, the approximate expressions for outage probability (OP) and average symbol error probability (ASEP) are derived in closed-form. Furthermore, to get more insights into the system performance, we derive the asymptotic OP at the high signal-to-noise ratio (SNR) regime and provide closed-form expressions for the system diversity order and coding gain. Finally, the accuracy of our theoretical analysis is validated through Monte-Carlo simulations. The obtained results show that the considered RIS scenario can provide a diversity order of <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$\frac{a}{2}K$</tex-math></inline-formula> , where <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$a$</tex-math></inline-formula> is a function of the Nakagami fading parameter <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$m$</tex-math></inline-formula> and the number of meta-surface elements <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$N$</tex-math></inline-formula> , and <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$K$</tex-math></inline-formula> is the number of RISs.
Effects of hydrological and climatic variables on cyanobacterial blooms in four large shallow lakes fed by the Yangtze River (2020)

Shallow lakes, one of the most widespread water bodies in the world, are easily shifted to a new trophic state due to external interferences. Shifting hydrologic conditions and climate change can cause cyanobacterial harmful algal blooms (CyanoHABs) in shallow lakes, which pose serious threats to ecological integrity and human health. This study analyzed the effects of hydrologic and meteorological variables on cyanobacterial blooms in Yangtze-connected lakes (Lake Dongting and Poyang) and isolated lakes (Lake Chao and Tai). The results show that (i) chlorophyll-a (Chl-a) concentration tends to decrease exponentially with increasing relative lake level fluctuations (RLLF) and precipitation, but to increase linearly with increasing wind speed and air temperature; (ii) Chl-a concentrations in lakes were significantly higher when RLLF < 100, precipitation < 2.6 mm, wind speed > 2.6 m s<sup>-1</sup>, or air temperature > 17.8 °C; (iii) the Chl-a concentration of Yangtze-isolated lakes was more significantly affected by water level amplitude, precipitation, wind speed and air temperature than the Yangtze-connected lakes; (iv) the RLLF and the ratio of wind speed to mean water depth could be innovative coupling factors to examine variation characteristics of Chl-a in shallow lakes with greater correlation than single factors.
MR elastography derived shear stiffness-a new imaging biomarker for the assessment of early tumor response to chemotherapy (2013)

These results demonstrate that magnetic resonance elastography-derived estimates of shear stiffness reflect an initial response to cytotoxic therapy and suggest that this metric could be an early and sensitive biomarker of tumor response to chemotherapy.

Optimum multiflow biorthogonal DMT with unequal subchannel assignment (2005)

We consider the design of biorthogonal, as opposed to orthonormal, discrete multitone (DMT) systems supporting multiple services in a single antennae setting. The services may have differing quality of service (QoS) requirements, quantified by bit rate and symbol error rate specifications. Different users on the system can be potentially assigned different number of subchannels. Our goal is to minimize the transmitted power given the QoS specifications for the different users, subject to the knowledge of the channel and colored interference at the receiver input of the DMT system. We find an optimum bit loading scheme that distributes the bit rate transmitted across the various subchannels, where the precise subchannels are assigned to each user, and an optimum transceiver. Key conclusions are i) relaxing the orthonormality constraint yields no performance improvement; ii) the optimum transceiver is unaffected by changing service characteristics, and depends only on the channel and interference conditions; iii) the QoS requirements, the number of users, and the number of subchannels assigned to the different users only affect bitloading and subchannel assignment.
Analysis of multi-infeed HVDC systems with inverter and rectifier connected to the same AC network (2010)

The sensitivity of the indices used in the analysis of the multi-infeed HVDC systems to the converter type has been analysed. Specifically, the impact on MIIF and CFII has been analyzed in more detail. The test system comprises the inverter of one HVDC system and the rectifier of another scheme connected to the same ac network. (5 pages)
Matching with Contracts (2005)

We develop a model of matching with contracts which incorporates, as special cases, the college admissions problem, the Kelso-Crawford labor market matching model, and ascending package auctions. We introduce a new “law of aggregate demand” for the case of discrete heterogeneous workers and show that, when workers are substitutes, this law is satisfied by profit-maximizing firms. When workers are substitutes and the law is satisfied, truthful reporting is a dominant strategy for workers in a worker-offering auction/matching algorithm. We also parameterize a large class of preferences satisfying the two conditions.
Absorption bleaching by stimulated emission in erbium-doped silicon-rich silicon nitride waveguides (2010)

Stimulated emission from sensitized erbium ions in silicon-rich silicon nitride is demonstrated by pump-probe measurements carried out in waveguides. A decrease in the photoinduced absorption of the probe at the wavelength of erbium emission is observed and is attributed to stimulated emission from erbium excited indirectly via localized states in the silicon nitride matrix.
MIMO Systems with Reconfigurable Antennas: Joint Channel Estimation and Mode Selection (2022)

Reconfigurable antennas (RAs) are a promising technology to enhance the capacity and coverage of wireless communication systems. However, RA systems have two major challenges: (i) High computational complexity of mode selection, and (ii) High overhead of channel estimation for all modes. In this paper, we develop a low-complexity iterative mode selection algorithm for data transmission in an RA-MIMO system. Furthermore, we study channel estimation of an RA multi-user MIMO system. However, given the coherence time, it is challenging to estimate channels of all modes. We propose a mode selection scheme to select a subset of modes, train channels for the selected subset, and predict channels for the remaining modes. In addition, we propose a prediction scheme based on pattern correlation between modes. Representative simulation results demonstrate the system's channel estimation error and achievable sum-rate for various selected modes and different signal-to-noise ratios (SNRs).
Resonant Beam SWIPT With Telescope and Second Harmonic (2022)

Simultaneous wireless information and power transfer (SWIPT) is a prospective technology that can handle the energy consumption and communication requirements in the Internet of Things. Resonant beam SWIPT (RB-SWIPT) scheme utilizes narrow optical beam as carrier and with spatially separated resonator structure, which can support high power and high rate SWIPT for mobile devices. However, the performance of original RB-SWIPT systems is limited by returning beam interference and transmission loss. In this paper, we propose a RB-SWIPT scheme for transmission-enhanced and anti-interference. The telescope internal modulator (TIM) and second harmonic generator (SHG) are adopted in the proposed system. The TIM can compress beams to reduce the transmission loss. The SHG can generate frequency-doubled beams to avoid interference. To evaluate the proposed system, we establish mathematical models to depict the beam transmission, energy conversion, electric power output and data receiving. Numerical results illustrate that the proposed system can achieve 18 bit/s/Hz spectral efficiency and deliver 8 W power over 100 m distance.
<title>Crack detection in lap-joints using acoustic emission</title> (1995)

Experiments have been conducted to assess the feasibility of autonomously detecting crack growth in an aircraft lap-joint using acoustic emission (AE) sensors. In a lap-joint the crack must be detected early and reliably so that a repair can be made at a reasonable cost, and unnecessary inspections can be eliminated. The location of the crack initiation is known to within a few fastener holes, making detection using AE possible. Representative waveforms from cracked lap-joint specimens, as well as results from a simpler specimen are presented. A method for distinguishing crack waveforms from fretting waveforms and noise sources is discussed. A self-organizing map is investigated as a means to identify crack signals. Lessons learned, and suggestions for future work are presented.
Thromboelastometry for guiding bleeding management of the critically ill patient: a systematic review of the literature. (2014)

A systematic review of the published literature clearly demonstrates the usefulness of thromboelastometry (ROTEM®) in detecting coagulation disorders in severe trauma, cardiac and aortic surgery, liver transplantation, and postpartum haemorrhage reliably and within a clinically acceptable turn-around time. In all of the above-mentioned scenarios, the transfusion of any allogeneic blood products could be reduced significantly using ROTEM®-guided bleeding management, thereby minimising or avoiding transfusion-related side effects. Based on the current body of evidence as assessed by the GRADE system, the use of ROTEM® may be recommended in particular for management of severe bleeding after trauma and during cardiac and aortic surgery. However, as laboratory testing contributes only one part of severe bleeding management, the implementation of safe and effective treatment algorithms must be ensured at the same time.
Residual Insulin Production and Pancreatic β-Cell Turnover After 50 Years of Diabetes: Joslin Medalist Study (2010)

Demonstration of persistence and function of insulin-producing pancreatic cells suggests the possibility of a steady state of turnover in which stimuli to enhance endogenous β cells could be a viable therapeutic approach in a significant number of patients with type 1 diabetes, even for those with chronic duration.
Integration of 5G Wireless into Hybrid Media Production Including SMPTE ST 2110 (2023)

Professional media production will in the future require more flexibility over where and how its operations are provided, including where there are multiple networks, which could include 5G, wired, cloud-based, and home networks. The broadcast industry’s adoption of live networked media systems is still relatively immature, especially in wireless and there is not yet a consistent and complete approach to describing architectures and the interfaces required for interoperability. This article describes a set of gateway functions for a professional media production using both 5G and wired (SMPTE ST 2110-based) media networks, in particular a scenario from the EU Horizon IC-41 Project 5G-RECORDS ( <uri xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">https://www.5g-records.eu/</uri> ) about a multicamera 5G-enabled broadcast studio. The Media Gateway (MG) converts media streams between the wireless and wired environments and the Media Orchestration and Control Gateway (MOCG) provides discovery, configuration, connection, and control of broadcast equipment deployed in various locations. In a ST 2110 environment, the latter is done in part through Advanced Media Workflow Association (AMWA) Networked Media Open Specifications (NMOS) APIs; however, this approach needs to be adapted for use in a 5G network, through the introduction of middleware components that decouple the wired and wireless. This article gives a detailed description of the wireless studio use-case and the approach taken by 5G-RECORDS in developing the MG and MOCG.
Topological Edge Transport in Twisted Double-Bilayer Graphene (2021)

Topological insulators realized in materials with strong spin-orbit interactions challenged the long-held view that electronic materials are classified as either conductors or insulators. The emergence of controlled, two-dimensional moire patterns has opened new vistas in the topological materials landscape. Here we report on evidence, obtained by combining thermodynamic measurements, local and non-local transport measurements, and theoretical calculations, that robust topologically non-trivial, valley Chern insulators occur at charge neutrality in twisted double-bilayer graphene (TDBG). These time reversal-conserving valley Chern insulators are enabled by valley-number conservation, a symmetry that emerges from the moire pattern. The thermodynamic gap extracted from chemical potential measurements proves that TDBG is a bulk insulator under transverse electric field, while transport measurements confirm the existence of conducting edge states. A Landauer-Buttiker analysis of measurements on multi-terminal samples allows us to quantitatively assess edge state scattering and demonstrate that it does not destroy the edge states, leaving the bulk-boundary correspondence largely intact.
Gonadal Function Recovery in Patients With Advanced Hodgkin Lymphoma Treated With a PET-Adapted Regimen: Prospective Analysis of a Randomized Phase III Trial (AHL2011) (2021)

PURPOSE The prospective, randomized AHL2011 trial demonstrated that the use of the doxorubicin, bleomycin, vinblastine, and dacarbazine regimen (ABVD) after two cycles of bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP escalated ) in early responders on the basis of a positron emission tomography (PET)–driven strategy was safe and minimized toxicity compared with standard 6 BEACOPP escalated cycles. This substudy investigated the benefit of this strategy in gonadal function and fertility in patients under 45 years old. METHODS Ovarian function was assessed by serum measurement of follicle-stimulating hormone (FSH), estradiol, and anti-müllerian hormone in women, and semen analysis, FSH, and testosterone levels were used to evaluate testicular function in men at baseline, end of treatment, and during 5 years of follow-up. RESULTS A total of 145 women and 424 men, enrolled between May 19, 2011, and April 29, 2014, were included. The risk of premature ovarian insufficiency (FSH &gt; 24 IU/L) and of having a low ovarian reserve (anti-müllerian hormone &lt; 0.5 ng/mL) was reduced after treatment in the PET-driven group (odds ratio [OR], 0.20; 95% CI, 0.08 to 0.50; P = .001 and OR, 0.15; 95% CI, 0.04 to 0.56, P = .005, respectively). Both parameters were correlated with age and dose of alkylating agents. However, no significant differences were observed in terms of pregnancy rates. Men in the PET-driven group had a higher recovery rate of sperm parameters after treatment compared with the standard BEACOPP escalated group, as well as a lower risk of severe testicular damage (OR, 0.26; 95% CI, 0.13 to 0.5; P &lt; .0001) and a higher likelihood of achieving pregnancy (OR, 3.7; 95% CI, 1.4 to 9.3; P = .004). CONCLUSION Although both treatments affected ovarian reserve and spermatogenesis, the PET-driven strategy decreased the risk of gonadal dysfunction and infertility in advanced Hodgkin lymphoma.
