Design and Calibration of a 3D-Printed Cup-Vane Wireless Sensor Node

There has been constant growth in the wind energy market. A study conducted in January 2018 by Global Market Insights Inc. predicted that the global wind energy market will surpass USD 170 billion by 2024. Before installation of a wind turbine, wind data must be collected from a prospective site for a minimum of one year. This has compelled the high demand for instruments used for collecting wind data. Various commercial cup anemometers and wind vanes have been manufactured for sale, some of which lack proper calibration or are not affordable for small-scale wind farmers, especially in developing countries. Wind data are a big data affair and call for instruments that handle them as such, unlike most commercial wind data collection instruments. This paper presents the design and calibration of a wireless 3D-printed cup-vane instrument for collecting wind data. This instrument represents a Wireless Sensor Node (WSN) in the Internet of Things (IoT). This study gave rise to an instrument system that was able to acquire wind data within a mean fitting deviation of ±0.063398 m/s, store them and present them wirelessly to an IEEE 802.15. 4 protocol sink node. This was verified in the lab using 1 m/s to 16 m/s wind speeds at the Armfield™ wind tunnel and outside in an open field with 1 m/s to 5 m/s wind speeds.
Gibbsianness and non-Gibbsianness in divide and color models

For parameters $p\in[0,1]$ and $q>0$ such that the Fortuin--Kasteleyn (FK) random-cluster measure $\Phi_{p,q}^{\mathbb{Z}^d}$ for $\mathbb{Z}^d$ with parameters $p$ and $q$ is unique, the $q$-divide and color [$\operatorname {DaC}(q)$] model on $\mathbb{Z}^d$ is defined as follows. First, we draw a bond configuration with distribution $\Phi_{p,q}^{\mathbb{Z}^d}$. Then, to each (FK) cluster (i.e., to every vertex in the FK cluster), independently for different FK clusters, we assign a spin value from the set $\{1,2,\. ,s\}$ in such a way that spin $i$ has probability $a_i$. In this paper, we prove that the resulting measure on spin configurations is a Gibbs measure for small values of $p$ and is not a Gibbs measure for large $p$, except in the special case of $q\in \{2,3,\. \}$, $a_1=a_2=\. =a_s=1/q$, when the $\operatorname {DaC}(q)$ model coincides with the $q$-state Potts model.
In vitro blood flow visualizations and cell-free layer (CFL) measurements in a microchannel network

Microvascular networks are not simple straight microchannels but rather complex geometries composed by successive asymmetric divergent and convergent bifurcations. Despite the extensive research work in this field, still lack of knowledge about the blood flow behavior in microvascular networks. The current study applies the most current advanced visualization and microfabrication techniques to provide further insights into to the blood flow in network geometries. Hence, by using a high-speed video microscopy system, blood flow measurements and visualizations of the cell-free layer (CFL) were performed along a microchannel network composed by several divergent and convergent bifurcations. The inlet flow rate was kept constant whereas the hematocrit (Hct) and the depth of the geometry was changed in order to evaluate their effects into the CFL thickness. The results, show clearly that the Hct has a significant impact on the CFL thickness whereas the effect of reducing the depth did not contribute to a noticeable change on the CFL. In addition, the in vitro blood flow results reported here provide for the first time that in microfluidic devices having several asymmetric confluences it is likely to have the formation of several CFLs not only around the walls but also in middle of the main channels just downstream of the last confluence apex. Although, to best of our knowledge there is no evidence that this kind of flow phenomenon also happens in vivo, we believe that for microvascular networks with similar geometries and under similar flow conditions tested in this work, this kind of phenomenon may also happen in vivo. Furthermore, the results from this study could be extremely helpful to validate current numerical microvascular network models and to develop more realistic multiphase numerical models of blood flow in micro-
Variable Spurious Noise Mitigation Techniques in Hysteretic Buck Converters

This work proposes a current-mode hysteretic buck converter with a spur-free constant-cycle frequency-hopping controller that fully eliminates spurs from the switching noise spectrum irrespective of variations in the switching frequency and operating conditions. As a result, the need for frequency regulation loops to ensure non-varying switching frequency (i.e. fixed spurs location) in hysteretic controllers is eliminated. Moreover, compared to frequency regulation loops, the proposed converter offers the advantage of eliminating mixing and interference altogether due to its spur-free operation, and thus, it can be used to power, or to be integrated within noise-sensitive systems while benefiting from the superior dynamic performance of its hysteretic operation. The proposed converter uses dualsided hysteretic band modulation to eliminate the inductor current imbalance that results from frequency hopping along with the output voltage transients and low-frequency noise floor peaking associated with it. Moreover, a feedforward adaptive hysteretic band controller is proposed to reduce variations in the switching frequency with the input voltage, and an alldigital soft-startup circuit is proposed to control the in-rush current without requiring any offchip components. The converter is implemented in a 0.35-μm standard CMOS technology and it achieves 92% peak efficiency.
Variational principle for the Wheeler–Feynman electrodynamics

We adapt the formally defined Fokker action into a variational principle for the electromagnetic-two-body problem. We introduce properly defined boundary conditions to construct a functional of a finite orbital segment into the reals. The boundary conditions for the variational principle are an end point along each trajectory plus the respective segment of trajectory for the other particle inside the light cone of each end point. We show that the conditions for an extremum of our functional are the mixed-type neutral equations with implicit state-dependent delay of the electromagnetic-two-body problem. We put the functional on a natural Banach space and show that the functional is Frechet differentiable. We develop a method to calculate the second variation for C2 orbital perturbations, in general, and, in particular, about circular orbits of large enough radii. We prove that our functional has a local minimum at circular orbits of large enough radii, at variance with the limiting Kepler action that has a.

Strongly coupled Skyrme–Faddeev–Niemi hopfions

The strongly coupled limit of the Skyrme–Faddeev–Niemi model (i.e. without quadratic kinetic term) with a potential is considered on the spacetime . For one-vacuum potentials two types of exact Hopf solitons are obtained. Depending on the value of the Hopf index, we find compact or non-compact hopfions. The compact hopfions saturate a Bogomolny bound and lead to a fractional energy–charge formula E ∼ |Q|1/2, whereas the non-compact solitons do not saturate the bound and give E ∼ |Q|. In the case of potentials with two vacua compact shell-like hopfions are derived. Some remarks on the influence of the potential on topological solutions in the full Skyrme–Faddeev–Niemi model or in the (3 + 1) Minkowski space are also made.

A BRANCH AND BOUND ALGORITHM FOR WORKFLOW SCHEDULING

Nowadays, people are connected to the Internet and use different Cloud solutions to store, process and deliver data. The Cloud consists of a collection of virtual servers that promise to provision on-demand computational and storage resources when needed. Workflow data is becoming an ubiquitous term in both science and technology and there is a strong need for new tools and techniques to process and analyze large-scale complex datasets that are growing exponentially. Scientific workflow is a sequence of connected tasks with large data transfer from parent task to children tasks. Workflow scheduling is the activity of assigning tasks to execution on servers and satisfying resource constraints and this is an NP-hard problem. In this paper, we propose a scheduling algorithm for workflow data that is derived from the Branch and Bound Algorithm.
A Distributed Control Scheme of Thermostatically Controlled Loads for the Building-Microgrid Community

In this paper, thermostatically controlled loads (TCLs), e.g., air conditioners, are utilized to mitigate the photovoltaic and load variations in a building-microgrid community, so that the whole community can provide ancillary services, e.g., fulfilling the power dispatch order from the main grid. First, a distributed control scheme with a two-layer hierarchical communication graph is proposed. The control gains are selected based on a linear quadratic regulator approach to achieve optimal control performance. Then, an initial value updating method is developed so that the dispatch order and local regulation signals are converted into the initial conditions for distributed control. With the proposed control scheme, the building-microgrid community can provide ancillary services while fairly sharing power and customers’ comfort requirement among all participated TCLs. The effectiveness of this control scheme is validated on a building-microgrid community with a variety of test cases.

The purpose of the study was to explore the combination of ICR with High Intensity Interval Training (HIIT) or continuous training over a 8-weeks on inflammatory and lipid profile indexes in overweight women. In the current quasi-experimental study, 36 overweight and obese women were randomly grouped in four groups (n = 9/group) for an additional 8 weeks as follows: 1) intermittent caloric restriction (N=9) (20% lower energy intake), 2) continuous training+ICR (N=11) (20% energy deficit created by 10% CR and 10% EE through CT), 3) High-Intensity Interval Training+ICR (N=9) (20% energy deficit created by 10% CR and 10% EE through HIIT) and 4) control (N=9) (remain on diet). Blood samples were collected to measure the inflammatory indexes (the number of environmental blood leukocytes and C-reactive protein) as well as lipid profile (total cholesterol, triglyceride, HDL and LDL). Data were analyzed using Shapiro–Wilk tests to investigate the natural distribution of the data; repetitive variance was also used to investigate the mean difference between phases and the interactive effect between phases and groups; Bonferroni post-hoc test was also used for comparing intergroup changes in the significance level of α < 0.05. Eight weeks of HIIT and continuous training with ICR led to significant changes in all indexes including lipid profile (HDL, LDL, total cholesterol, triglyceride), VO2max, CRP compared to the pre-test phase. Moreover, there was a significant intergroup difference in the indexes of lipid profile and CRP among control group and ICR, HIIT+ICR and ICR+ continuous groups, lastly, there was also an intergroup cholesterol index (ICR) and HIIT+ICR and ICR+continuous groups (p<0.05). Regarding VO2max, there was a significant intergroup difference between the control group and HIIT+ICR and ICR+ continuous groups (p<0.05). Due to the marked and noticeable effects of eight weeks of HIIT and continuous training along with ICR on inflammatory and lipid profile indexes in overweight women, it can be concluded that the combination of these interventions can be effective in controlling the weight and obesity.
Symplectic Manifolds with Vanishing Action-Maslov Homomorphism

The action--Maslov homomorphism $I\co\pi_1(\text{Ham}(X,\omega))\to\R$ is an important tool for understanding the topology of the Hamiltonian group of monotone symplectic manifolds. We explore conditions for the vanishing of this homomorphism, and show that it is identically zero when the Seidel element has finite order and the homology satisfies property $\mathcal{D}$ (a generalization of having homology generated by divisor classes). We use these results to show that $I=0$ for products of projective spaces and the Grassmannian of $2$ planes in $\C^4$.
Selective and Preferential Translocation of C 4-Labeled Sugars in White Ash and Lilac 1 ' 2

On the basis of sieve-tube-sap analyses of white ash, Zimmermann (15) has concluded that the sugars verbascose, stachyose, raffinose, sucrose and mannitol are translocation substances. Other evidelnce supporting this conclusion is Pristupa's (11) observation with pumpkin in which he found that trainslocated C14 occurred mainly as stachyose and to a lesser extent as raffinose and sucrose. Trip et al. (12) showed that leaves of white ash conitain, in addition to the above mentioned, the sugars mellibiose, maltose, galactose, glucose, fructose anld pentoses. Since there are maniy sugars in leaves, but only a few in the translocation stream it appears that there is a mechanism which selects the form in which carbohydrates are translocated. To further investigate this selective process a study was uindertakeni in whiclh C14 w%vas introduced either as C14O, or as Cl4-labeled sugars. This paper show s that only certain sugars are translocated and that they are translocated at different rates.
MICROLEAKAGE ALONG GLASSIX GLASS FIBRE POSTS CEMENTED WITH THREE DIFFERENT MATERIALS ASSESSED USING A FLUID TRANSPORT SYSTEM

Aim To evaluate microleakage along Glassix fibre posts cemented with three different materials. Methodology The root canals of central maxillary incisors were obturated and restored with Glassix posts (Harald Nordin sa, Chailly/Montreux, Switzerland) cemented with Harvard cement (Richter & Hoffmann, Harvard Dental GmbH, Berlin, Germany), Fuji PLUS cement (GC Corporation, Tokyo, Japan) and Variolink II cement (Vivadent, Schaan, Lichtenstein) in three groups of fifteen canals each. Twenty unrestored canals served as a control group, 10 obturated with gutta-percha and sealer, the remaining 10 with gutta-percha only. Coronal microleakage was evaluated using a fluid transport system. The movement of an air bubble in a capillary glass tube connected to the apex of the experimental root section was measured over 5-min. periods. Measuring was performed four times for each specimen and the mean values recorded. Analyses of variance and Duncan's test were performed. Results The highest values of microleakage occurred in the group cemented with Harvard cement, followed by Fuji PLUS and Variolink II cements. Fuji PLUS and Variolink II showed statistically significant (p < 0.00001) less microleakage compared with Harvard cement. Conclusion Canals with Glassix posts cemented with Variolink II cement had the least leakage as assessed using a fluid transport system.
Convergence of expansions in Schr\"odinger and Dirac eigenfunctions, with an application to the R-matrix theory

Expansion of a wave function in a basis of eigenfunctions of a differential eigenvalue problem lies at the heart of the R-matrix methods for both the Schr\"odinger and Dirac particles. A central issue that should be carefully analyzed when functional series are applied is their convergence. In the present paper, we study the properties of the eigenfunction expansions appearing in nonrelativistic and relativistic $R$-matrix theories. In particular, we confirm the findings of Rosenthal [J. Phys. G: Nucl. Phys. 13, 491 (1987)] and Szmytkowski and Hinze [J. Phys. B: At. Mol. Opt. Phys. 29, 761 (1996); J. Phys. A: Math. Gen. 29, 6125 (1996)] that in the most popular formulation of the R-matrix theory for Dirac particles, the functional series fails to converge to a claimed limit.
Efficacy of FOLFOX in Patients with Aggressive Pancreatic Neuroendocrine Tumors After Prior Capecitabine/Temozolomide

Background. 5-fluorouracil, leucovorin, and oxaliplatin (FOLFOX) has activity in pancreatic neuroendocrine tumors (pNETs), but its use is limited, partly because of toxicities. pNETs can often become aggressive over time. We evaluated the efficacy of FOLFOX in patients with aggressive pNETs who had progressed after capecitabine plus temozolomide (cap/tem) among other treatments. Materials and Methods. This was a retrospective study of all patients with well-differentiated metastatic pNETs, treated at an academic cancer center between January 2008 and June 2019, who received FOLFOX and had received cap/tem in the past. The primary endpoint was objective response rate. Results. Thirty-one patients met eligibility criteria. Twentyfive received FOLFOX, and six received FOLFOX with bevacizumab. Patients were heavily pretreated, having received a median of three prior lines of systemic therapy prior to FOLFOX (range, 1–8). Three (9.7%) patients had grade [G]1 tumors, 16 (51.6%) had G2, and 6 (19.4%) had G3, and grade was unspecified in 6 (19.4%) patients. Fourteen (45.2%) exhibited a best response of partial radiographic response per RECIST 1.1 criteria, 15 (48.4%) stable disease, and 2 (6.4%) progressive disease; overall response rate was 45.2% and disease control rate was 93.5%. Median progression-free survival was 6 months (95% confidence interval [CI], 5.0–7.0), and median overall survival was 16 months from onset of study treatment (95% CI, 11.3–20.7) and 67 months from date of diagnosis (95% CI, 49.8–84.2). Median duration of treatment was 3 months, and median duration of response was 2 months. Toxicity profile was consistent with known adverse events associated with this regimen. Conclusion. FOLFOX is active in aggressive, heavily pretreated pNETs that have progressed on prior cap/tem chemotherapy; response durations are relatively short. The Oncologist 2021;26:115–119 Implications for Practice: FOLFOX chemotherapy has robust activity in patients with rapidly progressive, heavily pretreated pancreatic neuroendocrine tumors (NETs), a setting in which few, if any, other options are likely to be effective. Durations of response, however, are relatively short, and new treatments are urgently needed for patients with aggressive transformation of pancreatic NETs.
Deep-learning based approach for forecast of water quality in intensive shrimp culture ponds

With the enormous development of aquaculture, reducing the impacts of effluent discharge and improving water quality had become a critical global environmental concern. It is important to assess and predict water quality in the environmental management process of shrimp mariculture. Meanwhile, the accurate forecast of water quality is still in the exploration stage at present. In this study, deep belief networks (DBN) model are used to forecast water quality in intensive shrimp culture. This method based on deep learning includes a five-layered structure to extract relationships between the quantitative characteristic of water bodies and water quality variables. The water quality can be forecasted by the Canadian Water Quality Index (WQI) obtained from the output layer of simulated model. The results show that the DBN model has a great potential to predict the water quality and the ability of generalization and accuracy of model are satisfied.
Neither p21 Nor 14-3-3 Prevents G2 Progression to Mitotic Catastrophe in Human Colon Carcinoma Cells after DNA Damage, But p21 Induces Stable G1 Arrest in Resulting Tetraploid Cells

p21 and 14-3-3 , which are both transcriptional products of p53, have been reported to play a role in the G2 DNA damage checkpoint in mammalian cells. Human colon carcinoma cells, isogenic except for the presence or absence of either p21 or 14-3-3 (T. A. Chan et al., Genes Dev., 14: 1584–1588, 2000), are useful models for analysis of the role of these proteins in checkpoint control. Here, we have examined mitotic behavior within a single cell cycle after DNA damage in these cell lines. Our results show that p21, but not 14-3-3 , imposes a significant G2 delay after DNA damage. After G2 delay, we found that all isogenic cells, including those competent for both p21 and 14-3-3 , adapt to the DNA damage checkpoint and progress into mitosis, where they undergo incomplete chromosome segregation and reenter G1 with a tetraploid DNA content. Strikingly, our results show that p21, but not 14-3-3 , activates a checkpoint in response to DNA damage that prevents continued cycling of the tetraploid cells that result from a mitotic catastrophe characterized by failure to complete cell division. These results demonstrate that a tetraploid DNA content is not a reliable criterion to establish that arrest occurs in G2. Also, the DNA damage checkpoint mediated by p53-dependent induction of p21 assures neither G2 arrest nor DNA repair sufficient to enable accurate chromosome segregation in human colon carcinoma cells. We conclude that p21, but not 14-3-3 , has a unique role in the induction of G1 arrest in tetraploid cells that results from mitotic catastrophe after DNA damage.
