Catadioptric sensors that approximate wide-angle perspective projections

We present two families of reflective surfaces that are capable of providing a wide field of view, and yet still approximate a perspective projection to a high degree. These surfaces are derived by considering a plane perpendicular to the axis of a surface of revolution and finding the equations governing the distortion of the image of the plane in this surface. We then view this relation as a differential equation and prescribe the distortion term to be linear. By choosing appropriate initial conditions for the differential equation and solving it numerically, we derive the surface shape and obtain a precise estimate as to what degree the resulting sensor can approximate a perspective projection. Thus these surfaces act as computational sensors, allowing for a wide-angle perspective view of a scene without processing the image in software. The applications of such a sensor should be numerous, including surveillance, robotics and traditional photography.
Three-way cross designs for test lines vs. control line comparisons

The selection of appropriate parental lines and crossing plans are the most important keys for a successful breeding programme. Three-way crosses are intermediate between single and double cross hybrids and hence are economical with respect to uniformity, yield, stability and the relative simplicity of selecting and testing. When a number of test lines are to be compared to a control line, the main interest of the experimenter centres around comparing test vs. control lines with a high precision. For such situations, two series of designs have been developed using partially balanced incomplete block designs and their association schemes. In the designs obtained, three-way crosses are arranged in incomplete blocks and hence heterogeneity in the experimental field can be controlled in blocks of smaller sizes. It is found that the proposed designs make test vs. control lines comparisons with a higher precision.
Data-Driven Scheme for Joint Estimation of Direction-of-Arrival and Frequency With Uniform Linear Array

This article presents a two-step dynamic mode decomposition (TSDMD) approach to estimate the direction of arrival (DOA) and frequency for multiple narrow-band sources with single uniform linear array (ULA). The proposed algorithm first decomposes the receiving spatial-temporal data into temporal dynamic modes and corresponding spatial spectrum that yields the DOA information. Then the decomposed temporal dynamic modes are analyzed via the augmented DMD to retrieve the frequency information. The estimated DOAs and frequencies are automatically paired without the extra computational cost with such a temporal-spectral correlated decomposition scheme. Also, the obtained spatial spectrum distribution implies the actual number of the sources, which enables the proposed method to be used for the unknown number of sources case in wireless communication. Simulations demonstrate that the TSDMD accurately and effectively retrieves the sources' DOA and frequency information. It is found that the new approach can provide comparable performance but with less execution time compared with previous works. Our work provides a practical data-driven scheme for joint angle-frequency estimation.

Subdivision connectivity remeshing via Teichmüller extremal map

Curvilinear surfaces in 3D Euclidean spaces are commonly represented by triangular meshes. The structure of the triangulation is important, since it affects the accuracy and efficiency of the numerical computation on the mesh. Remeshing refers to the process of transforming an unstructured mesh to one with desirable structures, such as the subdivision connectivity. This is commonly achieved by parameterizing the surface onto a simple parameter domain, on which a structured mesh is built. The 2D structured mesh is then projected onto the surface via the parameterization. Two major tasks are involved. Firstly, an effective algorithm for parameterizing, usually conformally, surface meshes is necessary. However, for a highly irregular mesh with skinny triangles, computing a folding-free conformal parameterization is difficult. The second task is to build a structured mesh on the parameter domain that is adaptive to the area distortion of the parameterization while maintaining good shapes of triangles. This paper presents an algorithm to remesh a highly irregular mesh to a structured one with subdivision connectivity and good triangle quality. We propose an effective algorithm to obtain a conformal parameterization of a highly irregular mesh, using quasi-conformal Teichmuller theories. Conformality distortion of an initial parameterization is adjusted by a quasi-conformal map, resulting in a folding-free conformal parameterization. Next, we propose an algorithm to obtain a regular mesh with subdivision connectivity and good triangle quality on the conformal parameter domain, which is adaptive to the area distortion, through the landmark-matching Teichmuller map. A remeshed surface can then be obtained through the parameterization. Experiments have been carried out to remesh surface meshes representing real 3D geometric objects using the proposed algorithm. Results show the efficacy of the algorithm to optimize the regularity of an irregular triangulation.
Maternal and Neonatal Outcomes in Intrahepatic Cholestasis of Pregnancy

The aims of our study were to evaluate the maternal and fetal outcomes of intrahepatic cholestasis of pregnancy (ICP). In this observational, retrospective case–control study, we included all pregnant women who gave birth with a diagnosis of ICP between January 2010 and December 2020 at the Unit of Obstetrics and Gynecology, University Hospital of Messina. The data were compared with those from a control group of pregnant women who did not have ICP. One hundred twenty-nine and eighty-five patients were included, respectively, in the study and in the control group. There was a significant difference between the two groups in the incidence of hypothyroidism, thrombophilia, gestational diabetes, gestational hypertension, postpartum hemorrhage, and preterm delivery, which were more frequent in the ICP patients. No neonatal adverse events were recorded, although a significant difference in the meconium-stained amniotic fluid condition was noted. After a 24-month follow-up, 48/129 patients with ICP accepted to be reassessed by liver ultrasound, elastographic examination, and liver function blood tests. No patient showed signs of chronic liver disease. This study confirmed a higher probability of adverse short-term maternal outcomes in ICP pregnant patients, but a lower probability of adverse short-term fetal outcomes and the absence of a long-term maternal risk of chronic liver disease.

A Bacteriophage Microgel Effectively Treats the Multidrug-Resistant Acinetobacter baumannii Bacterial Infections in Burn Wounds

Multidrug-resistant (MDR) Acinetobacter baumannii (A. baumannii) is one of the major pathogens present in burn wound infections. Biofilm formation makes it further challenging to treat with clinically available antibiotics. In the current work, we isolated the A. baumannii-specific bacteriophages (BPABΦ1), loaded into the chitosan microparticles followed by dispersion in gel, and evaluated therapeutic efficacy against MDR A. baumannii clinical strains. Isolated BPABΦ1 were found to belong to the Corticoviridae family, with burst size 102.12 ± 2.65 PFUs per infected host cell. The BPABΦ1 loaded chitosan microparticles were evaluated for quality attributes viz. size, PDI, surface morphology, in vitro release, etc. The developed formulation exhibited excellent antibiofilm eradication potential in vitro and effective wound healing after topical application.
Comparisons of Two Bioelectrical Impedance Devices and Manual versus Sensor-Based Short Physical Performance Batteries for Assessment of Muscle Mass and Physical Performance

The assessment of muscle mass and physical performance is essential for the diagnosis of sarcopenia. This study examined the validity of bioimpedance analysis (BIA) and a sensor-based short physical performance battery (SPPB) device for analyzing appendicular skeletal muscle mass (ASM) and physical performance. Forty-one older adults were measured for ASM and physical performance with two BIA devices (InBody770 vs. T-SCAN PLUS III) and two SPPB devices (manual mSPPB vs. sensor-based sSPPB). Validity statistics included the intraclass correlation coefficient (ICC) and Bland–Altman plots to examine the agreement of data from the BIA (InBody770 vs. T-SCAN PLUS III) and the SPPBs (mSPPB vs. sSPPB). There was a significant ICC for skeletal muscle mass between the T-SCAN PLUS III and InBody770 devices (ICC = 0.8822; p < 0.0001). The mSPPB and sSPPB values showed agreement across all components: 0.8654 for the total scores, 0.8879 for the walking speed, 0.8889 for the chair stand, and 0.6863 for the standing balance. No systemic bias was observed between the two methods for the BIA and SPPB devices. Measurements using the T-SCAN PLUS III and sSPPB seem to be highly correlated with the InBody770 and mSPPB devices in older adults and may be valid for assessing muscle mass and physical performance.
Physical interactions in non-ideal fluids promote Turing patterns

Turing’s mechanism is often invoked to explain periodic patterns in nature, although direct experimental support is scarce. Turing patterns form in reaction–diffusion systems when the activating species diffuse much slower than the inhibiting species, and the involved reactions are highly nonlinear. Such reactions can originate from cooperativity, whose physical interactions should also affect diffusion. We here take direct interactions into account and show that they strongly affect Turing patterns. We find that weak repulsion between the activator and inhibitor can substantially lower the required differential diffusivity and reaction nonlinearity. By contrast, strong interactions can induce phase separation, but the resulting length scale is still typically governed by the fundamental reaction–diffusion length scale. Taken together, our theory connects traditional Turing patterns with chemically active phase separation, thus describing a wider range of systems. Moreover, we demonstrate that even weak interactions affect patterns substantially, so they should be incorporated when modelling realistic systems.
The Effect of Cryogenic Temperatures on the Lateral Heat Spreading in InGaAs/InP HEMTs

The recent developments in quantum computing architectures have caused an increasing interest in cryogenic low-noise amplifiers (LNAs) due to their role in the qubit readout chain. Advanced quantum computers with many qubits will require cryogenic integration of thousands of LNAs. Minimizing LNA power dissipation while maintaining low noise will be of key importance due to the limited available cooling power in cryostats. In addition, self-heating (SH) and heat dissipation of cryogenic LNAs represent limiting factors in the device’s performance and integration. While SH is predicted to increase in transistor channels at cryogenic temperatures, large-scale thermal spreading outside of active devices due to SH is not well understood. Here, the 2-D heat flow due to the SH of InGaAs/InP high electron mobility transistors (HEMTs) is experimentally studied. We realize a matrix of Schottky diode thermal sensors close to the active device, which allows us to obtain a full 2-D temperature mapping with respect to the power dissipated by the HEMT. Measurements are performed in the temperature range of 300–4.2 K. Results indicate that HEMT large-scale thermal spreading due to SH is suppressed at lower ambient temperatures. Below 77 K, the increase of surface temperature at a distance $< 12 \mu \text{m}$ from the active area is less than the measurement sensitivity (0.5 K). Therefore, we conclude that the increased SH in the channel at cryogenic conditions does not result in increased surface heating. These results build on our understanding of the opportunities for integrated cryogenic electronics in quantum computers.
Previous motor task performance impacts phase-based EEG resting-state connectivity states

The resting human brain cycles through distinct states that can be analyzed using microstate analysis and electroencephalography (EEG) data. This approach classifies, multichannel EEG data into spontaneously interchanging microstates based on topographic features. These microstates may be valuable biomarkers in neurodegenerative diseases since they reflect the resting brain’s state. However, microstates do not provide information about the active neural networks during the resting-state. This article presents an alternative and complementary method for analyzing resting-state EEG data and demonstrates its reproducibility and reliability. This method considers cerebral connectivity states defined by phase synchronization and measured using the corrected imaginary phase-locking value (ciPLV) based on source-reconstructed EEG recordings. We analyzed resting-state EEG data from young, healthy participants acquired on five consecutive days before and after a motor task. We show that our data reproduce microstates previously reported. Further, we reveal four stable topographic patterns over the multiple recording sessions in the source connectivity space. While the classical microstates were unaffected by a preceding motor task, the connectivity states were altered, reflecting the suppression of frontal activity in the post-movement resting-state.
Toward Verifying Cooperatively Scheduled Runtimes Using CSP

In this article, we present the novel verification of synchronous channel communication and channel alternation (choice) by considering the environment within which our primitives are executing. Our work is in exploring development of a multi-threaded scheduler for a cooperatively scheduled process-oriented language, ProcessJ. We use communicating sequential processes to produce formal specifications for the implementation of the various parts of the language runtime (scheduler, runtime components, and generated code). We use established communicating sequential process specifications that model channel communication and choice as well as the formal verification tool FDR to formally prove that the implementations are correct and behave as expected, when executed by our scheduler (the execution environment). Our approach is novel and not seen in similar research, as we consider the behavior of the systems we examine under the restrictions imposed by an execution environment (a runtime system, a scheduler, an operating system, etc.) and show that even with such restrictions the channel communication and alternation work. More specifically, we show correctness when a system is executed by the ProcessJ cooperative scheduler. The main contributions of this work are in the models defined and method undertaken to verify cooperatively channel communication and choice.
3D-PTV on large particles in the free-surface vortex

Wastewater pumping stations can experience problems due the presence of floating particles of solidified fat and grease. To transport this debris, the ability of free-surface vortices as transport mechanism is investigated. An experimental set-up is developed where the behaviour of large particles (0.02 - 0.04 m) in the vortex flow are analysed. An 3D-particle tracking method based of 6 iPhone® cameras was used to record the position of the particles in the vortex. Based on the measured particle acceleration, the hydrodynamic forces on the particle are derived. This novel 3D-PTV method was found to generate consistent information on the movement of the particles in the vortex flow field.
Optimal design of cyclically symmetric trusses with frequency constraints using cyclical parthenogenesis algorithm

Special kinds of structures exhibit repetitive patterns that can be used in the process of structural analysis in order to decrease the required computational time. This is especially helpful when a structure should be analyzed numerous times as in the structural optimization problems. In this article, weight optimization of cyclically symmetric spatial trusses subjected to frequency constraints is performed utilizing such repetitive patterns. Large initial eigenproblems are first decomposed into smaller and less time-consuming problems using an efficient block diagonalization technique. A recently developed meta-heuristic method, cyclical parthenogenesis algorithm, is then utilized to perform the optimization task. Three numerical examples are optimized to illustrate the viability and efficiency of the proposed method.
A formulation for optimal design problem of compliant displacement magnification mechanisms based on effective energy concept

A compliant mechanism is a structure designed to be flexible in order to achieve a specified motion as a mechanism. Such mechanisms can enable a variety of functions. In particular, the operation of highly sensitive sensors and actuators in industrial applications often requires reliable and flexible displacement magnification mechanisms. It is well known that topology optimization offers a useful and powerful method for compliant mechanism design, where displacement in a targeted direction at an output port is to be maximized based on the use of artificial spring components located at the boundaries of the input and output ports. However, such spring components are not always a fundamental requirement. This letter presents a formulation for a compliant displacement magnification mechanism design based on the concept of effective energy. Several numerical examples are provided to confirm the utility of the proposed formulation.
