Structural and functional changes in marine microbial communities associated with oxygen dynamics

The outer Western Crimean Shelf of the Black Sea is a natural laboratory to investigate effects of stable oxic vs. varying hypoxic conditions on seafloor biogeochemical processes and benthic community structure. Bottom water oxygen concentrations varied between normoxic (175 μmol O2L −1) and hypoxic (<63 μmol O2L −1) or even anoxic/sulfidic conditions within a few kilometres distance. Variations in oxygen concentrations between 160 and 10 μmol L−1 even occurred within hours close to the chemocline at 134 m water depth. Total oxygen uptake, including diffusive as well as fauna-mediated oxygen consumption, decreased from >15 mmol m−2 d−1 in the oxic zone to <9 mmol m d in the hypoxic zone, correlating with changes in macrobenthos composition. Benthic diffusive oxygen uptake rates, comprising microbial respiration plus reoxidation of inorganic products, were around 4.5 mmol m−2 d−1, but declined to 1.3 mmol m−2 d−1 at oxygen concentrations below 20 μmol L−1. Measurements and modelling of pore water profiles indicated that reoxidation of reduced compounds played only a minor role in the diffusive oxygen uptake, leaving the major fraction to aerobic degradation of organic carbon. Remineralization efficiency decreased from 100% in the oxic zone, to 50% in the oxic-hypoxic, to 10% in the hypoxic-anoxic zone. Overall the faunal remineralization rate was more important, but also more influenced by fluctuating oxygen concentrations than microbial and geochemical oxidation processes.
Dynamique de l'appariement tourbillonnaire en milieu stratifie et stratifie tournant

Une des caracteristiques les plus remarquables des fluides geophysiques est la presence de stratification, c'est-a dire d'un gradient vertical de densite, qui induit une structure en couches horizontales. Lindborg (1999) et Billant & Chomaz (2001) ont propose que la dynamique au sein de ces couches est tridimensionnelle et non bidimensionnelle comme cela etait suppose auparavant. Les derniers ont aussi propose un mecanisme de selection de l' epaisseur de ces couches : l'instabilite zigzag qu'ils ont observee dans le cas particulier d'une paire de tourbillons contra-rotatifs. Cependant, les paires de tourbillons contra-rotatifs sont rarement observees dans l'ocean et l'atmosphere contrairement aux couples de tourbillons co-rotatifs. De plus, l'appariement de tourbillons co-rotatifs est le processus dominant en turbulence bidimensionnelle responsable du transfert d'energie des petites vers les grandes echelles. Au cours de ma these, je me suis donc interessee a la dynamique de tourbillons co-rotatifs verticaux dans un fluide stratifie. Une instabilite associee au meme effet physique que l'instabilite zigzag a ete decouverte. Elle decorrele verticalement l'appariement de ces tourbillons, suggerant que l' instabilite zigzag est generique et affecte tout ecoulement stratifie constitue de plus d'un tourbillon. L'analyse numerique de stabilite lineaire a montre que cette instabilite consiste en un mode deplacement et selectionne une echelle verticale proportionnelle a l' echelle de flottabilite definie comme Fb, ou F est le nombre de Froude horizontal et b la distance entre les deux tourbillons. Son taux de croissance est proportionnel au champ d'etirement cree par un tourbillon sur son compagnon. L'origine physique de cette instabilite a ete identifiee grâce a une etude asymptotique : elle provient du couplage entre le mode de deplacement d'un tourbillon et le champ d'etirement genere par l'autre tourbillon. Observations experimentales et Simulations Numeriques Directes montrent que les non-linearites n'inhibent pas le developpement de l'instabilite zigzag qui entraine bien une decorrelation verticale de l'ecoulement selon une echelle proportionnelle a l'echelle de flottabilite. Enfin, l'effet de la rotation de la Terre a ete etudie et nous avons montre que l'instabilite Zigzag reste active en presence de la force de Coriolis. Son taux de croissance est independant du taux de rotation. En regime fortement tournant, on retrouve l'approximation quasi-geostrophique : l'instabilite zigzag est similaire a l'instabilite ''tall-column'' decouverte par Dritschel & de la Torre Juarez (1996) et la longueur d'onde la plus instable est proportionnelle a Fb/Ro, ou Ro est le nombre de Rossby. Cette instabilite affecte donc les ecoulements geophysiques sur une large gamme d' echelles aussi bien dans l'ocean que dans l'atmosphere.

Synergistic Optimization Design Method to Improve the Overload Capacity and Efficiency of Canned Permanent Magnet Synchronous Motor for Vacuum Pump

The efficiency and overload capacity are crucial performance factors during the design of the canned permanent magnet synchronous motors (CPMSMs) intended for driving vacuum pumps, due to their unique operational characteristics. The conventional multi-objective optimization design method is not suitable for the CPMSM due to the need to carefully consider additional influential factors, including the flat structure, eddy current losses in the cans, can thickness, and can material. To enhance the efficiency and overload capacity of the CPMSM, this paper introduces a synergistic optimization design approach that integrates the equivalent magnetic circuit method and the finite element method. A design example of a 1.5 kW CPMSM is presented, and experiments are performed to verify the effectiveness of the proposed method.
Effects of Pig Dietary n-6/n-3 Polyunsaturated Fatty Acids Ratio and Gender on Carcass Traits, Fatty Acid Profiles, Nutritional Indices of Lipid Depots and Oxidative Stability of Meat in Medium–Heavy Pigs

The effects of different dietary n-6/n-3 polyunsaturated fatty acids (PUFA) ratios and gender on key carcass traits, as well as the nutritional and technological quality of lipids in medium–heavy pig tissues have been poorly studied. To investigate the subject, 24 Large White, barrows and gilts, evenly divided into two groups of 12, were fed from 80 kg of live-weight (LW) until slaughter at 150 kg LW, either a high (9.7:1) (HPR) or low (1.4:1) (LPR) dietary n-6/n-3 PUFA ratio. On individual samples of longissimus thoracis muscle (LTM), subcutaneous (SF) and perirenal (PF) adipose tissues (ATs), the fatty acid (FA) composition was determined by gas chromatography, and lipid nutritional indices (LNIs) were calculated. The oxidative stability of meat was evaluated by determining the malondialdehyde content on raw and cooked (24 h postmortem) and refrigerated (8 days postmortem) LTM samples. The carcass traits did not vary between genders and diets. The LPR group showed a higher n-3 PUFA level and a lower n-6/n-3 PUFA ratio in all the tissues examined and better LNI, especially in the ATs. Diet did not affect the oxidative stability of meat. Gender did not influence the n-6/n-3 PUFA ratio, while barrows showed improvements in some LNI in ATs. Reducing the n-6/n-3 ratio in the diet of growing–finishing medium–heavy pigs improved the FA profile in all tissues and most LNI in ATs without impairing the oxidative stability of meat.

Distributed Online Mirror Descent With Delayed Subgradient and Event-Triggered Communications

This paper investigates the distributed online multi-agent convex-constrained optimization with limited network bandwidth and feedback delay. The distinctive feature is that each agent is associated with a loss function that changes over time. It is desirable to employ an event-triggered communication protocol during the information exchange process to conserve network resources. Then, by adopting the Bregman divergence, we propose a delayed-subgradient-based event-triggered online distributed mirror descent (DS-ET-ODMD) algorithm that operates under delayed-full-information feedback. Under the DS-ET-ODMD algorithmic framework, we establish upper bounds for both static and dynamic regret of each agent, ensuring that the growth of such regrets is sublinear with respect to the time horizon $T$ as the trigger threshold gradually approaches zero. Finally, we provide distributed online estimation and target tracking problems as the simulation examples to verify our proposed algorithm.
Coupling effects of P-waves and S-waves based on cyclic triaxial tests with cyclic confining pressure

In the earthquakes with high intensities,the effects of P-waves on the soil layers cannot be ignored.The coupling effects of S-waves and P-waves are simulated by the specific stress paths in the cyclic triaxial tests with cyclic confining pressure.The influences of the phase differences and ratios between cyclic shear stress and cyclic normal stress on the behavior of cyclic strain are studied.It is found that the specific stress paths which are composed of both cyclic shear stresses and cyclic normal stresses are appropriate to simulate the coupling effects of S-waves and P-waves.The phase difference strongly influences the cyclic strength of saturated clays,i.e.,when the phase angle is 180°,the cyclic strength is the lowest,and when the phase angle is 0°,the cyclic strength is the highest.With the increasing ratios,the development speeds of cyclic strain are becoming more different from the results of conventional cyclic triaxial tests.These findings indicate that the effects of P-waves are significant,and in some cases the conventional cyclic triaxial tests may overestimate the cyclic strength of saturated clays,which is adverse for aseismatic design.
The Application of Permanent Magnet Synchronous Motor with Small Electrical Time Constant in Fiber Positioner

With the development of cutting-edge multi-object spectrographs, fiber positioners located in the focal plane are being scaled down in size, and miniature hollow-cup Permanent Magnet motors are now being considered as a suitable replacement for Faulhaber Precistep stepper motors. However, the small electrical time constant of such coreless motors poses a challenge, as the problem of severe commutation torque ripple in a fiber positioner running a position loop has been tricky. To overcome this challenge, it is advised to increase the Pulse Width Modulation (PWM) frequency as much as possible to mitigate the effects of the current fluctuation. This must be done while ensuring adequate resolution of the PWM generator. By employing a voltage open-loop field-oriented control based on a modulation frequency of 1 MHz, the drive current only costs 25 mA under a 3.3 V power supply. The sine degree of phase current is immaculate, and the repeat positioning accuracy can reach 2 μm. Moreover, it is possible to further shrink the bill of devices and the layout area of the Printed Circuit Board, especially in size-sensitive applications. This device has been developed under the new generation of The Large Sky Area Multi-Object Fiber Spectroscopic Telescope.
Joint Optimization of Active and Reactively Loaded Passive Dipoles for Beam Steering for Future Wireless Applications

In this article, we develop a novel algorithm for jointly optimizing the excitation voltages and the load impedances of arbitrary arrays of multiple active and multiple reactively loaded passive dipoles. The proposed algorithm hinges on obtaining a closed-form expression for the optimal excitation voltages of the active elements as a function of the load reactances. Noting that the array gain is a nonconvex function of these reactances, we develop an upper bound on the array gain and we use this bound and the excitation voltages that achieve it to guide the search for the optimal load reactances. Our numerical results show that the proposed technique tends to achieve the upper bound within a relatively small gap.
Single Actuator Tendon Driven Two Finger Linkage Gripper with Strong Pinch and Adaptable Cylindrical Grasp

This paper presents the design and development of a single actuator tendon driven two-finger linkage gripper that can perform both strong pinch and adaptable cylindrical grasp. The gripper mechanism consists of an anthropomorphic linkage finger with an additional revolute joint driven by a single actuator and a fixed thumb. The gripper can achieve a maximum pinch force of 11.7 N and an adaptable grasping ranging from 30 mm to 145 mm diameter, making it suitable for various applications, such as pick-and-place tasks in robotics and automation. Moreover, complaint design makes it suitable for the safe physical human robot interaction. In addition, proposed linkage finger’s characteristics were evaluated through kinematic analysis, simulation and experimental tests of prototype. The proposed gripper design is simple, low-cost, and easy to implement, making it an attractive alternative to more complex and expensive gripper designs.
High-frequency variants in PKA signaling-related genes within a large pediatric cohort with obesity or metabolic abnormalities

Introduction Pediatric obesity has steadily increased in recent decades. Large-scale genome-wide association studies (GWAS) conducted primarily in Eurocentric adult populations have identified approximately 100 loci that predispose to obesity and type II diabetes. GWAS in children and individuals of non-European descent, both disproportionately affected by obesity, are fewer. Rare syndromic and monogenic obesities account for only a small portion of childhood obesity, so understanding the role of other genetic variants and their combinations in heritable obesities is key to developing targeted and personalized therapies. Tight and responsive regulation of the cAMP-dependent protein kinase (PKA) signaling pathway is crucial to maintaining healthy energy metabolism, and mutations in PKA-linked genes represent the most common cause of monogenic obesity. Methods For this study, we performed targeted exome sequencing of 53 PKA signaling-related genes to identify variants in genomic DNA from a large, ethnically diverse cohort of obese or metabolically challenged youth. Results We confirmed 49 high-frequency variants, including a novel variant in the PDE11A gene (c.152C>T). Several other variants were associated with metabolic characteristics within ethnic groups. Discussion We conclude that a PKA pathway-specific variant search led to the identification of several new genetic associations with obesity in an ethnically diverse population.
High sensitivity refractive index sensor based on double peanut-shaped and etched multimode fiber structures

A fiber optic refractive index (RI) sensor based on an etched multimode fiber (MMF) with a double peanut-shaped structure is proposed and experimentally demonstrated. The sensor consists of two peanut-shaped and a section of etched MMF tapered fiber structure. The excitation of the fundamental mode to higher-order modes is facilitated by using the beam splitting/coupling effect of the double peanut-shaped and etched taper structures, and the higher-order modes can be excited into an evanescent field. In the sensing medium, the stronger the evanescent field, the stronger the energy shock between the fiber and the sensing environment. Experimental results showed that the sensitivity was 326.52 nm/RUI and 823.91 nm/RUI when the etched waist taper diameter was 51.92 μm and the glycerol solution index ranged from 1.3395 to 1.3945 and 1.3945 to 1.4200, respectively. Compared to the MMF sensor structure without etching, the RI sensitivity is improved by about 2 times. In addition, the temperature characteristics of the sensor were investigated over a range of 30 °C–100 °C, and the results showed a maximum temperature sensitivity of only 30.24 pm °m−1. The sensor structure has a low-temperature sensitivity and the temperature effect on the RI measurement results is negligible within the allowable error range. The sensor has the advantages of simple fabrication, wide measurement range, good stability, low cost, and compact structure, which has potential application value in the field of RI detection.
Elasticity of plagioclase feldspars

Elastic properties are reported for eight plagioclase feldspars that span compositions from albite (NaSi3AlO8) to anorthite (CaSi2Al2O8). Surface acoustic wave velocities measured using Impulsive Stimulated Light Scattering and compliance sums from high‐pressure X‐ray compression studies accurately determine all 21 components of the elasticity tensor for these triclinic minerals. The overall pattern of elasticity and the changes in individual elastic components with composition can be rationalized on the basis of the evolution of crystal structures and chemistry across this solid‐solution join. All plagioclase feldspars have high elastic anisotropy; a* (the direction perpendicular to the b and c axes) is the softest direction by a factor of 3 in albite. From albite to anorthite the stiffness of this direction undergoes the greatest change, increasing twofold. Small discontinuities in the elastic components, inferred to occur between the three plagioclase phases with distinct symmetry ( C1¯ , I1¯ , and P1¯ ), appear consistent with the nature of the underlying conformation of the framework‐linked tetrahedra and the associated structural changes. Measured body wave velocities of plagioclase‐rich rocks, reported over the last five decades, are consistent with calculated Hill‐averaged velocities using the current moduli. This confirms long‐standing speculation that previously reported elastic moduli for plagioclase feldspars are systematically in error. The current results provide greater assurance that the seismic structure of the middle and lower crusts can be accurately estimated on the basis of specified mineral modes, chemistry, and fabric.
Analysis of residential lighting in Poland: results from a winter term survey

In 2020, an international project on residential lighting started and was implemented in four countries (Poland, Sweden, UK and Turkey). This article presents the results of a survey carried out in Poland, in the winter term between November 2020 and January 2021. A total of 125 Polish residents (59 women, 65 men, one person did not wish to specify gender) participated in the survey. A variety of data was collected on the respondents and their assessments as well as on their satisfaction with day-and artiﬁcial lighting in residential living spaces. The results from questionnaires were analyzed with STATISTICA 13.3. Descriptive statistics and Spearman rank order correlations were adopted to identify the light-related aspects, lighting patterns, and respondents’ perception of day-and artiﬁcial lighting conditions in living areas. The results revealed that satisfaction with daylighting in the living area, both in summer and winter, was signiﬁcantly correlated with daylighting level, daylighting uniformity, sunlight exposure and view-out. The results also revealed that satisfaction with artiﬁcial lighting was signiﬁcantly correlated with artiﬁcial lighting level, artiﬁcial lighting uniformity and color rendering. The results provide valuable information on lighting and factors that inﬂuence the luminous environment in residential living spaces.
3-D Line Segment Reconstruction With Depth Maps for Photogrammetric Mesh Refinement in Man-Made Environments

3-D line segments contain richer geometric and structural information than 3-D point clouds in man-made environments, which is beneficial for providing constraints to refine point-cloud-based mesh models or build accurate wireframes. However, the efficient reconstruction of 3-D line segments with high scene coverage from multiview images is still challenging. In this study, the depth maps obtained from the point cloud generation procedure are exploited to decrease the search range of 2-D line segment correspondences to improve the efficiency, precision, and recall rate of 2-D line segment matching, thereby improving the construction efficiency and scene coverage of 3-D line segments. For a line segment on the reference image (called reference line segment) of an image pair, a reliable virtual line segment is produced by projecting several sampled points of the reference line segment onto the search image based on the corresponding depth information. Then, a purely geometrical similarity measurement under the constraints of the virtual line segment is designed to obtain 2-D line segment matches. Using the 2-D line segment correspondences of all image pairs, a multiview clustering operation is performed to construct 3-D line segments from the redundant 2-D matches. Finally, a simple 3-D-line-segment-based mesh model refinement method is designed, and the reconstructed 3-D line segments are employed to improve the quality of the point-cloud-based mesh model. In our experiments, five open-source datasets are adopted to qualitatively and quantitatively evaluate the performance of the proposed 3-D line segment reconstruction method and the potential of 3-D line segments on mesh model refinement. The experimental results show that the proposed 3-D line segment reconstruction method performs better than the state-of-the-art methods. Specifically, on five open-source datasets, our method exhibits an average improvement of 47.28% in the number of reconstructed 3-D line segments over the best one among the compared methods. In addition, the experimental results of the mesh model refinement show that the addition of 3-D line segments is beneficial for improving the quality of the point-cloud-based mesh model.
Local Recurrent Melanoma Treated with BRAF and MEK Inhibitors Despite Adjuvant Anti-Programmed Cell Death Protein 1 Antibody Therapy

The current standard therapies for patients with advanced melanoma include immunotherapy with an anti-programmed cell death protein 1 (anti-PD-1) antibody 1 . Anti-PD-1 antibodies prolong recurrence-free survival in high-risk melanoma patients, but some patients experience recurrence within 1 year. One study reported that patients who experienced disease recurrence during adjuvant anti-PD-1 antibody therapy had a minimal response to anti-PD-1 monotherapy but BRAF and MEK (BRAF/MEK) inhibitors showed clinical utility. However, these patients were only followed up for a few months 2 . A
