Measuring the dimensionality of compact extra dimensions with inspiral gravitational waves from black-hole binaries

Gravitational waves from coalescing black-hole binaries (BHBs) were recently observed by the advanced LIGO detectors. Based on the perturbation analysis, for general Kaluza-Klein theories with compact extra dimensions, we find a 1st-order post-Newtonian correction to the inspiral gravitational waveforms of black-hole binaries, that comes from the variations of the volume of the extra dimensions in near source zones. Such correction depends on a new parameter with n the dimensionality of the extra space and it is irrelevant to the particular choice of the topology of the extra space. For the ideal case of a black-hole binary system following nearly circular orbital motion with almost equal or intermediate mass ratio, such higher-dimensional corrections to the chirping amplitude are worked out. Giving the power of tracing inspiral waves from coalescing massive BHBs with high signal-to-noise ratios, the planned space-borne antennas such as the eLISA and DECIGO may give us a measurement of the parameter χ in the near future and may serve us as new probes in the searching for the evidence of the hidden compact dimensions.
Ultracompact on-chip photothermal power monitor based on silicon hybrid plasmonic waveguides

Abstract We propose and demonstrate an ultracompact on-chip photothermal power monitor based on a silicon hybrid plasmonic waveguide (HPWG), which consists of a metal strip, a silicon core, and a silicon oxide (SiO2) insulator layer between them. When light injected to an HPWG is absorbed by the metal strip, the temperature increases and the resistance of the metal strip changes accordingly due to the photothermal and thermal resistance effects of the metal. Therefore, the optical power variation can be monitored by measuring the resistance of the metal strip on the HPWG. To obtain the electrical signal for the resistance measurement conveniently, a Wheatstone bridge circuit is monolithically integrated with the HPWG on the same chip. As the HPWG has nanoscale light confinement, the present power monitor is as short as ~3 μm, which is the smallest photothermal power monitor reported until now. The compactness helps to improve the thermal efficiency and the response speed. For the present power monitor fabricated with simple fabrication processes, the measured responsivity is as high as about 17.7 mV/mW at a bias voltage of 2 V and the power dynamic range is as large as 35 dB.
Speech Enhancement Using Variational Autoencoders

This paper discusses the experimental details of speech enhancement using variational autoencoders (VAE). A joint VAE architecture is formulated, and a training protocol that strikes a balance between speech enhancement and VAE correctness is defined. Extended short-term objective intelligibility (ESTOI) is used to measure the intelligibility of enhanced speech. The proposed approach is implemented using MFCC and STFT features on a benchmark dataset and we report, on an average, 2 times improvement in ESTOI for enhanced speech using MFCC over STFT features across all noise levels. Further, the proposed approach using MFCC features shows significant improvement in denoising very noisy speech, as opposed to marginal improvement on relatively clean speech.
Influence of a Commercial Synbiotic Administered In Ovo and In-Water on Broiler Chicken Performance and Meat Quality

The present study aimed to test the synbiotic PoultryStar® solUS delivered in ovo to evaluate its effect on hatchability, productive performance and meat quality, compared to its post-hatch administration in water. On the twelfth day of embryonic incubation, 1200 fertile eggs were divided into synbiotic groups injected with 2 mg/embryo (T1) and 3 mg/embryo (T2), a saline group injected with physiological saline and an uninjected control group (C). After hatching, 120 male chicks/group were reared and chicks from the saline group were supplemented with the synbiotic via drinking water (T3). Hatchability was low in both T1 and T2 groups. Growth performance was not affected by the treatments. However, in the second rearing phase (15–36 days), birds from the C and T3 groups were heavier than T1 birds, due to a higher feed intake and daily weight gain. Neither route of synbiotic administration influenced final body weight (at 56 days), weight and yield of the carcass or commercial cuts. Physico-chemical properties, total lipid, cholesterol and fatty acid composition of breast muscle were not affected by the treatments. Considering its exploratory nature, this study has raised many questions that need further investigation, such as the bioactive combination and the effect on embryonic development.
Data Protection and Online Platforms

: Everyone needs data to succeed in today’ s world economy. The information extracted from it form the basis of competitiveness and growth for each player in the digital marketplace, and information built on the disclosures made by individuals when using online services has become an important asset in the digital economy. While digitization has contributed to the dynamic evolution of competition, the market position has also become a growing concern. This paper focuses on whether data can be considered a key factor in the creation of monopoly positions during the development of platforms, and suggests the introduction of the essential facilities principle to mitigate the data monopoly phenomenon, promote market competition, and facilitate industrial innovation and technological development.
Specification-Compliant Driving Corridors for Motion Planning of Automated Vehicles

It is crucial for automated vehicles to explicitly comply with specifications, including traffic rules, to ensure their safe and effective participation in road traffic. Such compliance is also essential for vehicle manufacturers to avoid liability claims in the event of accidents. We propose a novel approach addressing the problem of specification-compliant motion planning for automated vehicles. Our approach couples set-based reachability analysis with automata-based model checking and outputs specification-compliant driving corridors. These driving corridors serve as motion planning constraints and expedite the generation of trajectories complying with specifications expressed in metric temporal logic. In contrast to existing works, our approach efficiently and exhaustively verifies all driving corridors of an automated vehicle, leveraging mature model checking techniques. We demonstrate the applicability, effectiveness, and efficiency of our approach using various specifications on scenarios from the CommonRoad benchmark suite. Moreover, we benchmark the performance of our prototype against multiple scenarios, indicating that our approach is real-time capable.
Evolving Nutritional Needs in Cystic Fibrosis

The course of cystic fibrosis (CF) as a nutritional illness is diverging since the introduction of highly effective modulator therapy, leading to more heterogeneous phenotypes of the disease despite CF genetic mutations that portend worse prognosis. This may become more evident as we follow the pediatric CF population into adulthood as some highly effective modulator therapies (HEMT) are approved for those as young as 1 year old. This review will outline the current research and knowledge available in the evolving nutritional health of people with CF as it relates to the impact of HEMT on anthropometrics, body composition, and energy expenditure, exocrine and endocrine pancreatic insufficiencies (the latter resulting in CF-related diabetes), vitamin and mineral deficiencies, and nutritional health in CF as it relates to pregnancy and lung transplantation.
Mis‐Specification Testing in Retrospect

The primary objective of this paper is threefold. First, to undertake a retrospective view of Misâ€ Specification (Mâ€ S) testing, going back to the early 20th century, with a view to (i) place it in the broader context of modeling and inference and (ii) bring out some of its special features. Second, to call into question several widely used arguments undermining the importance of Mâ€ S testing in favor of relying on weak probabilistic assumptions in conjunction with generic robustness claims and asymptotic inference. Third, to bring out the crucial role of Mâ€ S testing in securing trustworthy inference results. This is achieved by extending/modifying Fisher's statistical framework with a view to draw a clear line between the modeling and the inference facets of statistical induction. The proposed framework untangles the statistical from the substantive (structural) model and focuses on how to secure the adequacy of the statistical model before probing for substantive adequacy. A case is made for using joint Mâ€ S tests based on customâ€ built auxiliary regressions with a view to enhance the effectiveness and reliability of probing for potential statistical misspecifications.
Improved algorithm for point cloud registration based on fast point feature histograms

Abstract. Point cloud registration is very important in three-dimensional (3-D) point cloud data processing as its results directly affect 3-D object reconstruction and other applications. Currently, there are many methods for point cloud registration, but these methods are not able to simultaneously solve the problem of both efficiency and precision. We propose a method of point cloud registration based on fast point feature histogram (FPFH), in which feature points are first extracted from the point cloud dataset according to FPFH and four point-to-point correspondences are found within some given constraints regarding their features, distances, and location relationships. Then, additional point pairs are added on the basis of the initial four point pairs until the number of point pairs satisfies the requirements for point cloud registration. Finally, a rigid transformation matrix is calculated from the correspondence of the point pairs. The results show that there is both a high efficiency and precision in most types of datasets when using this method for point cloud registration.

Nonsingular Brans-Dicke- Λ cosmology

We discuss a Brans-Dicke model with a cosmological constant, a negative value of the $w$ parameter, and an arbitrary (in general nonvanishing) scale factor at the big bang. The Friedmann equations for a flat universe are considered. The current observational values for Hubble constant ${H}_{0}$ and deceleration parameter ${q}_{0}$ play the role of initial conditions. We follow the approach of Uehara and Kim in order to solve field equations analytically. In K. Uehara and C. W. Kim [Phys. Rev. D 26, 2575 (1982)] only positive values of $w$ were considered; we extend the study to a complete set of possible $w$ values. Our main result is that the scale factor (during its evolution back in time direction) may not vanish, unlike in the standard $\ensuremath{\Lambda}\mathrm{CDM}$ case. In other words, the considered model demonstrates a cosmological bounce instead of the initial singularity. The famous formula (24), that leads to the bounce, is valid only for the dust-filled universe with $p=0$ and, therefore, is not adequate for the early universe hot stage when the bounce happens. So, our results are qualitative in nature and must be used to obtain initial values for the hot stage of the Universe.
Efficient Implementation of a Genetic Algorithm for the Capacitated Vehicle Routing Problem on a High-Performance FPGA

The Capacitated Vehicle Routing Problem (CVRP) is one of the most relevant optimization problems in operations research and logistics nowadays. While current state-of-the-art solutions to this problem implement evolutionary approaches such as Genetic Algorithms (GAs) on GPUs and multi-core CPUs, this work focuses on implementing a GA for CVRP on a high-performance FPGA to achieve an improved calculation efficiency: While maintaining a comparable solution quality and speed, the FPGA consumes only a fraction of the energy required by traditional computing platforms. This is achieved through leveraging algorithmic parallelism by a custom-fitted hardware architecture, combined with customized data representation for efficient processing.
Kink degeneracy and rogue potential flow for the (3+1)-dimensional generalized Kadomtsev-Petviashvili equation

The breather-type kink soliton, breather-type periodic soliton solutions and rogue potential flow for the (3+1)-dimensional generalized Kadomtsev-Petviashvili equation are obtained by using the extended homoclinic test technique and homoclinic breather limit method, respectively. Furthermore, some new non-linear phenomena, such as kink and periodic degeneracy, are investigated and the new rational breather solutions are found out. Meanwhile, we also obtained the rational potential solution and it is just a rogue wave. These results enrich the variety of the dynamics of higher-dimensional non-linear wave field.
Role of CO2 Laser on SBS between Dental Porcelain and Composite Resin Repair Process

Background. The surface modification of porcelain material can be conducted by mechanical, chemical, or laser means. This study investigated the CO2 laser effect on porcelain to enhance bonding with composite resin. Materials and methods. A total of 33 blocks of feldspathic porcelain were randomly divided into 3 groups of 10. Additionally, three specimens were used in scanning electronic microscopy and energy-dispersive spectroscopy tests. Group I was treated with 9.5% hydrofluoric acid (HF), Group II with a 5 W CO2 laser, and Group III with CO2 followed by etching with 9.5% HF. Then, a Bisco intraoral repair kit was used, followed by the application of repair composite resin (Tetric N Ceram) on the porcelain surface using a Teflon mold and light-curing source. Shear bond strength (SBS) was assessed by using a digital universal testing machine, and failure modes were evaluated. Data were analyzed by analysis of variance (ANOVA) and least significant difference test. Results. A high significant difference in roughness and SBS was found amongst the tested groups P < 0.001 . SBS and roughness for Group III were significant at P < 0.05 , and the lowest value was observed in Group II. The cohesive mode of failure was dominant in Groups I and III, whereas adhesive failure was dominant in Group II. Conclusion. The surface treatment of porcelain with CO2 laser followed by HF application can enhance roughness and SBS, and can be recommended when extra retention during repair indication.
The In-flight icing warning system ADWICE for European airspace - Current structure, recent improvements and verification results

The Advanced Diagnosis and Warning System for Aircraft Icing Environments (ADWICE) has been in development since 1998 in a collaboration between the German Aerospace Centre (DLR), Deutscher Wetterdienst (German Weather Service, DWD) and the Institute of Meteorology and Climatology of the Leibniz Universität Hannover (IMuK). ADWICE identifies atmospheric regions containing supercooled liquid water where aircraft icing can occur. Running operationally at DWD since 2002, ADWICE is used at the German Advisory Centres for Aviation (Luftfahrtberatungszentrale) to support pilots in route planning by warning of hazardous in-flight icing conditions. The model domain covers Europe and the Mediterranean coast of North Africa with a horizontal grid spacing of about 7 km and 30 vertical hybrid levels. The warning system consists of two algorithms. Based on output data of the operational numerical weather prediction model COSMO-EU (Consortium of Small-Scale Modelling – Europe), the Prognostic Icing Algorithm (PIA) allows the forecast of areas with an icing hazard. The Diagnostic Icing Algorithm (DIA) realises a fusion of forecast, observational and remote sensing data such as satellite data to describe the current icing hazard. Both algorithms create a three-dimensional icing product containing information about the likely icing scenario and its associated icing intensity. This paper describes the current structure of ADWICE, its output, as well as its diagnosis and forecast skill. For verification, the output of the two algorithms was compared with pilot observations over Europe. The results show satisfactory values for the probability of detection and the volume efficiency.

Efectos genéticos aditivos y no aditivos para características reproductivas en dialelo Holstein-Suizo Pardo en clima subtropical húmedo

El cruzamiento permite aprovechar las diferencias genéticas aditivas entre razas, también permiten hacer uso de la heterosis y de la complementariedad. Por lo tanto, se necesita generar información de la eficacia de las cruzas en comparación con las razas puras, bajo las condiciones de interés. El objetivo fue cuantificar el impacto de los efectos genéticos aditivos y no aditivo para días a primer estro (DPE), días a primer servicio (DPS), días abiertos (DA), servicios por concepción (SPC), intervalo entre partos (IP) y duración de la gestación (DG). Se utilizó la información productiva y genealógica de hembras provenientes de un dialelo entre Holstein (HO) y Suizo Pardo (SP), un total de 148 vacas de las razas HO (n=43), SP (n=64) y sus cruzas reciprocas HO-SP (n=20) y SP-HO (n=21). Se utilizaron contrastes para estimar la heterosis individual y las diferencias entre los efectos genéticos directos y entre los efectos genéticos maternos con base en los modelos de Dickerson. Los resultados mostraron que la heterosis y las diferencias entre los efectos maternos no fueron significativos (P>0.05) para ninguna de las características estudiadas. Las diferencias entre efectos genéticos directos solo fueron importantes (P<0.05) para SPC y DG. En conclusión, la heterosis generada por el cruzamiento entre HO y SP no influyó sobre la eficiencia reproductiva de las hembras. Los efectos maternos no fueron diferentes entre HO y SP. Los efectos genéticos directos para SPC y DG favorecieron a la raza SP.
Dimensionless collisionality scans for core particle transport in JET

Density peaking increases in the inner core (r/a=0.3) from 0.3 to 2.7 and in the outer core (r/a=0.8) from 1.6 to 3.5 when ν∗ decreases from 0.47 to 0.09 in JET H-mode plasmas while density peaking does not depend on ν∗ in JET L-mode plasma. For this particular scan, experimental evidence indicates that a dominant part of this peaking originates from NBI fuelling and inward pinch is a subdominant fraction. This is supported by the simple linear runs with GYRO although much more work is needed here to make a conclusion. More discharges are needed to quantify more precisely the fractions of these two contributions and also much more work is required on the modelling front to make exact comparisons.
Electronic and magnetic properties in Mn‐doped IIIA‐nitride monolayers

Based on first‐principles calculations plus Hubbard U, we have studied the electronic structure and magnetic properties of Mn‐doped IIIA‐nitride monolayers. The substitution of Mn for Al or Ga atom induces a total magnetic moment of 4.00 µB per dopant, independent of the choice of functional. The doped AlN system is half‐metallic at GGA + U (<5 eV) level, but is a magnetic semiconductor at the HSE06 and GGA + U (≥5 eV) levels. The doped GaN system is a magnetic semiconductor at these two levels. The Mn‐doped InN converts into metal without magnetism, due to the robust p–d hybridization between the Mn‐3d and N‐2p states and the delocalized sd states. The Mn atoms have a clear clustering tendency with the FM state in the AlN and GaN hosts. The long‐ranged ferromagnetic coupling is observed along the ⋯N‐Al/Ga⋯ zigzag edge directions, which can be attributed to p–d hybridization mechanism. These results suggest that the Mn‐doped AlN and GaN monolayers are promising candidates for preparing spintronic devices at the nanoscale.
