EVALUATION OF MEXICAN NATIVE AND HYBRID MAIZE (ZEA MAYS) SILAGES FOR SUSTAINABLE MILK PRODUCTION

Background. Maize cultivation and dairy cattle represent two of the main economic activities in Mexico. Objective. Determine the forage yield (ton / ha) and forage quality of the maize silage produced in Mexico and estimate potential milk production. Methodology. For this purpose, 13 studies carried out in Mexico, were analyzed according to study area (north vs. center of Mexico) and variety (native vs. hybrid). For inclusion in the final database, the studies should have been including agronomic and chemical variables such as: dry matter yield (DMY) (ton / ha), plant density (number of plants / ha), dry matter content (DM), crude protein (CP), neutral detergent fiber (NDF), ash or organic matter (OM), dry matter digestibility (DMD), neutral detergent fiber digestibility (NDFD), starch and fat content. The data were analyzed using a completely randomized statistical design. Results. The forage DMY (dry matter yield) / ha, and the milk production (ton DM / ha) were higher (P <0.0001) for the central region with respect to the northern region. Regarding to the milk production (kg milk/ ha) the native silages produced more (P <0.05) than the hybrids. A positive correlation was observed for the content of NEL (net energy of lactation) (MJ / kg DM) and kg milk / ton DM. Implications. The native maize of Mexico thus has the potential to provide greater production of milk / ha and kg Milk/ per ton DM with respect to hybrid maize, due to the higher digestibility of the NDF that causes the higher NEl. Conclusions. The use of native maize in Mexico is a viable alternative for use as a silage in feed for dairy cows, with higher milk production per hectare and per ton of dry matter compared to hybrid maize.
Identification of a Partial and Selective TRPV1 Agonist CPIPC for Alleviation of Inflammatory Pain

Transient receptor potential vanilloid 1 (TRPV1) is a non-selective cation channel, predominantly expressed in a subset of peripheral sensory neurons for pain signaling. Topical application of agonist capsaicin for desensitizing TRPV1 currents has been approved for relief of chronic pain. However, the potent TRPV1 capsaicin is not ingestible and even topical capsaicin causes common side effects such as skin irritation, swelling, erythema and pruritus, suggesting that a mild TRPV1 agonist might be helpful for reducing side effects while reliving pain. In this study, we reported on a partial and selective TRPV1 agonist 4-(5-chloropyridin-2-yl)-N-(1H-indazol-6-yl)piperazine-1-carboxamide named CPIPC that was modified based on targeting the residue Arg557, important for conversion between the channel antagonism and agonism. Whole-cell patch clamp recordings indicated a concentration-dependent activation of TRPV1 currents by CPIPC with an EC50 of 1.56 ± 0.13 μM. The maximum efficacy of CPIPC (30 μM) was about 60% of saturated capsaicin (10 μM). Repetitive additions of CPIPC caused TRPV1 current desensitization in both TRPV1-expressing HEK293 cells and dorsal root ganglion (DRG) sensory neurons. Oral administration of CPIPC dose-dependently alleviated inflammatory pain in mice. Further site-directed mutagenesis combined with molecular docking revealed that residue Arg557 is critical for TRPV1 activation by CPIPC. Taken together, we identified a novel partial and selective TRPV1 agonist CPIPC that exhibits antinociceptive activity in mice.
Evidence of Interstellar Na I Structure at Scales Down to 15 AU in Low-Density Gas

We present high-resolution Hubble Space Telescope/Space Telescope Imaging Spectrograph and multiepoch KPNO coudé feed observations of multiple interstellar lines toward the binary system HD 32039/40. Comparisons of the Na I profiles observed over a period of 4.25 yr reveal significant temporal variation in the Na I column in at least one component, implying that there is structure at scales on the order of the proper motion (~15-21 AU). Large differences are also observed among multiple components in the profiles of the neutral species between the binary sight lines (5060 AU separation). In addition, significant differences in the S II profile are seen between the stars—the first optical/UV detection of small-scale variations in a dominant ion. Measurements of the C I fine-structure excitation in the variable components suggest that the densities in these components are ~20-200 cm-3, significantly lower than the densities inferred in past H I 21 cm and Na I studies.
Effect of Dietary Enrichment with Flaxseed, Vitamin E and Selenium, and of Market Class on the Broiler Breast Meat—Part 2: Technological and Sensorial Traits

The influence of diet enrichment with flaxseed, selenium and vitamin E, and market class on breast meat was investigated in terms of technological and sensorial quality of breast meat. A randomized complete block design with an experimental unit of n = 6000 broilers receiving a standard or enriched diet, and slaughtered at 37 (light class), 47 (medium class), or 57 (heavy class) days of life, was developed. Then, enriched and standard breast muscles from every market class were studied for their technological and sensorial traits—both at 24 h post-mortem and after one month of frozen storage—by a statistical multiple linear model. Redness and yellowness of muscles significantly (p < 0.05) increased and decreased with increasing market age. Moreover, the yellowness significantly (p < 0.05) raised after frozen storage. However, obtained data were always indicative of a normal meat color. The water holding capacity improved following fed enrichment and significantly (p < 0.05) worsened after frozen storage. For the sensory analysis, juiciness and chewing rest of meat resulted significantly (p < 0.05) improved with increasing slaughtering age and diet enrichment, as well as their mutual interaction, while they deteriorated after frozen storage. Overall, fresh and enriched muscles from heavy broilers had the best technological and sensorial traits, thus, confirming that market size and diet should be highly considered to obtain breast meat with greater consumer acceptance.
Hybrid LSTM-PCA-Powered Renewable Energy-Based Battery Life Prediction and Management for IoT Applications

To ensure self-sustainable and long-term requirement of Internet of Things (IoT) operation, energy harvesting (EH) is a promising technique. In this work, battery prediction problems and joint access control are studied in a IoT cell system with a base station (BS) and EH user equipment (UE) with limited uplink access channels. Every UE present holds a limited capacity rechargeable battery. In order to address this issue, we take into consideration the uplink wireless system with “N” EH user equipment (UE) along with the base station. To build the UE uplink access control, the first step involves the application of hybrid Q network (HQN) with long short-term memory (LSTM) to tackle the access control issue. This technique maximizes the uplink transmission sum rate. The LSTM DQN network designed has two layers with battery prediction and joint access control solution. The first layer is developed to predict battery levels, while the next layer generates the access control information based on channel information along with the predicted values. This network is trained to decrease the discounted prediction loss and increase long-term discounted sum rate, at the same time by training the two layers jointly. In recent years, IoT sensors have played a major role in collecting and monitoring data gathered from real-world applications such as environmental monitoring, transportation, urban security, smart energy management, agriculture, and health care. Several of these appliances function with batteries. Hence, the primary task would be to predict the batter’s lifespan and provide a timeframe to replace or recharge the battery. The battery life used in an IoT network is predicted with the help of a hybrid random forest-principal component analysis (PCA) regression algorithm with machine learning.

THE HYPER ORDER OF SOLUTIONS OF SECOND ORDER DIFFERENTIAL EQUATIONS AND SUBNORMAL SOLUTIONS OF PERIODIC EQUATIONS

In this paper, we obtain a precise estimation of the hyper order of solutions for a class of second order linear differential equations, and investigate the condition of the existence of nontrivial subnormal solution for a class of second order periodic equations. These results generalize the results of Gundersen, Steinbart [5] and Wittich [10]. Our methods of proofs are different from the methods applied in [5, 10].
Effect of Date Fruit Consumption on the Glycemic Control of Patients with Type 2 Diabetes: A Randomized Clinical Trial

Objective. Date fruit has been reported to have benefits in type 2 diabetes (T2D), though there is a concern, given the high sugar content, about its effects on glycemic control. Design and Setting. Prospective, interventional, randomized, parallel study. Participants. In total, 79 patients with T2D (39 male and 40 female). Intervention. Participants were randomly allocated to either 60 g date fruit or 60 g raisins daily of the equivalent glycemic index (amount split, given as midmorning and midafternoon snack) for 12 weeks. Main Outcome Measures. The primary outcome was to investigate the effect of date fruit on HbA1c and fasting blood glucose, and their variability, in patients with T2D in comparison to the same glycemic load of raisins. The secondary outcomes were to determine whether date fruit affected cardiovascular risk by measuring fasting lipids, C-reactive protein (CRP), blood pressure, and insulin resistance (IR) as measured by Homeostatic Model Assessment (HOMA-IR). Results. In total, 61 (27 female and 34 male) of 79 patients completed the study. There was no difference between or within groups for HbA1c or HbA1c variability, fasting glucose or glucose variability, insulin resistance (HOMA-IR), insulin sensitivity (HOMA-S), beta cell function (HOMA-B), the disposition index, lipids, systolic (SBP) or diastolic blood pressure (DBP), or C-reactive protein (CRP) (p > 0.05). Conclusion. No improvement in glycemic indices was seen following supplementation of 60 g daily date fruit or raisins, though neither had a deleterious effect on glycemic control over a 12-week period, indicating their safety when consumed in T2D. Additionally, no beneficial therapeutic effects of date fruit on other cardiovascular indices in T2D were seen.
EUVE Observations of U Geminorum in Outburst

We have observed U Gem during the peak and declining phases of a wide outburst in 1993 December with the {ital Extreme} {ital Ultraviolet} {ital Explorer} ({ital EUVE}) satellite. At peak, U Gem was one of the brightest EUV sources in the sky. The spectrum of the source is complex. Fitted to a blackbody spectrum, the apparent temperature at peak is {approximately}140,000 K, the luminosity is {approximately}4{times}10{sup 34}({ital D}/90 pc){sup 2} ergss{sup {minus}1}, and the minimum size of the emitting region is comparable to that of the white dwarf (WD). If the EUV emission arises primarily from the boundary layer, then the boundary layer luminosity in U Gem is comparable to the disk luminosity. The EUV source is partially eclipsed at orbital phases 0.6{endash}0.8. The eclipse spectrum, which we associate with a wind emerging from the vicinity of the white dwarf, is dominated by emission features. The identification of these emission features with transitions expected in a relatively cool ({ital T}{lt}160,000 K), photoionized plasma helps to resolve a controversy concerning the ionization state of winds of dwarf novae. The EUV lines arise from the dominant ionization states of the wind, and their strengths suggest that the wind mass-loss rate, atmore » least in U Gem, is a substantial fraction of the WD accretion rate. {copyright} {ital 1996 The American Astronomical Society. }« less
Phylogeography of mangrove pit vipers (Viperidae, Trimeresurus erythrurus‐purpureomaculatus complex)

We present the first multilocus molecular phylogeny focused on mangrove pit vipers of the Trimeresurus erythrurus‐purpureomaculatus complex based on novel topotypic material and expanded geographic sampling. Previously inferred paraphyly of T. purpureomaculatus was resolved and our results demonstrate distinct phylogeographic patterns that are latitudinally stratified and consistent with isolation‐by‐distance and isolation‐by‐environment. A clear genetic break is detected at the Isthmus of Kra biogeographic divide and niche overlap among major genetic clades is limited. The association between colour polymorphisms and phylogeographic structure suggests that contemporary or historical introgression between T. erythrurus and T. purpureomaculatus could have occurred. This study provides a clear roadmap to guide future genomic research to improve our understanding of this charismatic, yet poorly studied group of snakes.
The Relationship Between Knowledge of Dental and Oral Health and The Number of Functioning Teeth in Indonesian Elderly People

Tooth loss is a cause of decreased masticatory function that affects the oral cavity and general health in the elderly. The elderly was expected to have at least 20 working teeth, meaning that the masticatory, aesthetic and speech functions were considered normal, although less than 32 teeth. This study aims to determine the relationship between the dental and oral health of the elderly with the number of functioning teeth at the Hargo Dedali Nursing Home in Surabaya. This type of research is analytic with a cross sectional design. The total population is 38 elderly and the research sample is 35 elderly using random sampling technique with purposive sampling. Method analyzed technique uses the Pearson Correlation test. The result of this research is the elderly population is female. Their age range is between 60-92 years. Questions were answered correctly overall by 48.1%. The most questions answered incorrectly about tooth loss by 67.9%. There are 3 elderly who have 20 working teeth. The average working gear is 9.3 or 9 teeth per person. Data are normally distributed. There is a relationship between the two variables (0.000 < 0.05). Conclusion of this research is smaller the value of dental and oral health knowledge of the elderly, the less the number of teeth that work. The benefits of this research can provide awareness and motivation for families, nursing home managers, health workers in an effort to serve dental and oral health in the elderly.
MicroRNA-613 Enhances Nasopharyngeal Carcinoma Cell Radiosensitivity via the DNA Methyltransferase 3B/Tissue Inhibitor of Matrix Metalloproteinase-3/Signal Transducer and Activator of Transcription-1/Forkhead Box O-1 Axis

Nasopharyngeal carcinoma (NPC) is a common malignancy of the nasopharynx, and radioresistant represents the main obstacle in NPC treatment. Malignant transformation of normal cells is driven by genetic and epigenetic changes, which are primarily manifested as changes in miRNA levels and DNA methylation status. microRNA (miR)-613 plays an inhibitory role in several types of cancer. Herein, the current study sought to explore the roles of miR-613 in NPC cell radiosensitivity. miR-613 expression patterns in NPC tissues were detected, and its correlation with clinical indexes was analyzed. NP-69 and C666-1 cell lines were selected for cellular experimentation. Radioresistant cell line C666-1R was obtained by fractionated radiation. Cell viability, survival fraction, and apoptosis were detected by CCK-8, colony formation assay, and flow cytometry. The binding relation between miR-613 and DNMT3B was verified by dual-luciferase and RIP assays. miR-613 was lowly expressed in NPC tissues and cells, with lower expression levels in C666-1R than C666-1, and further correlated with lymph node metastasis, tumor size, and tumor metastasis. miR-613 overexpression reduced C666-1R cell viability and survival fraction and increased apoptosis, while C666-1 cells with silencing miR-613 presented the opposite trends. miR-613 targeted DNMT3B. miR-613 and DNMT3B overexpression led to enhanced C666-1R cell viability and survival fraction and decreased apoptosis. miR-613 reduced TIMP3 methylation and elevated TIMP3 protein level by inhibiting DNMT3B. miR-613 enhanced NPC radiosensitivity by inhibiting the DNMT3B/TIMP3/STAT1/FOXO1 pathway. Collectively, miR-613 inhibited DNMT3B, reduced TIMP3 methylation, and increased TIMP3 protein level, thus inhibiting the STAT1/FOXO1 pathway and enhancing the radiosensitivity of NPC cells.
Quantitative Inheritance of Ten Root Traits in Sweetpotatoes1

A parent-offspring study of 40 sweetpotato lines grown in 6 environments provided heritability (%) estimates for 10 root characters as follow: weight, 41; number edible roots, 32; veining, 30; growth cracks, 51; flesh oxidation, 64; shape, 62; flesh color, 66; cortex thickness, 45; skin color, 81; and skin purpling, 74. In most cases the realized changes due to selection fit the predictions very well. The additive component of genetic variance was relatively more important than the non-additive for all traits except veining and number of edible roots. The study illustrates the usefulness of quantitative genetic approaches to sweetpotato breeding.
Arbitrary settling time control with prescribed performance for high‐order nonlinear systems

This paper studies an arbitrary convergence time tracking controller design problem for high‐order nonlinear systems. Our aim is to enhance the existing free‐will arbitrary time control (FATC), which cannot track time‐varying reference signals. To do so, a new nonautonomous equation is firstly introduced to enable an arbitrary settling time stability for one‐order systems. Then, a prescribed performance control (PPC) technology is integrated for general high order systems. By a backstepping Lyapunov analysis with iteratively contructed nonautonomous equations, it is proved that the closed‐loop system satisfies the prescribed performance and all signals of the closed‐loop system are arbitrary settling time stable (ASTS). Compared with the existing results, the tracking control problem with arbitrary convergence time is addressed by a continuous control law, which shows a better transient performance also. Simulation results confirm the effectiveness of the proposed control method.
Improving the Power Quality of Island Microgrid With Voltage and Frequency Control Based on a Hybrid Genetic Algorithm and PSO

An efficient power control technique for inverter-based distributed generation (DG) in an islanded microgrid is investigated in this work. The objective is to raise the caliber of the electricity pumped from network-connected DGs. The characteristics that are taken into consideration include voltage and frequency control, dynamic response, and steady-state response, particularly when the microgrid is operating in island mode or when there is a load change. The control method consists of an internal current control loop and an external power control loop based on a synchronous reference frame and a conventional PI controller. The power controller is designed based on voltage-frequency (VF) control. In addition, an intelligent search technique that combines Particle Swarm Optimization (PSO) and Genetic Algorithm (GA) is utilized to automatically modify power controller parameters. The control technique in this research is that the DG modifies its control mode to modify the system voltage and frequency when the microgrid is islanded or load conditions change. The simulation results in MATLAB/SIMULINK software show that the proposed control system has been able to improve the power quality well.
Object-based evaluation of a numerical weather prediction model’s performance through forecast storm characteristic analysis

AbstractTraditional pixel-versus-pixel forecast evaluation scores such as the critical success index (CSI) provide a simple way to compare the performances of different forecasts; however, they offer little information on how to improve a particular forecast. This paper strives to demonstrate what additional information an object-based forecast evaluation tool such as the Method for Object-Based Diagnostic Evaluation (MODE) can provide in terms of assessing numerical weather prediction models’ convective storm forecasts. Forecast storm attributes evaluated by MODE in this paper include storm size, intensity, orientation, aspect ratio, complexity, and number of storms. Three weeks of the High Resolution Rapid Refresh (HRRR) model’s precipitation forecasts during the summer of 2010 over the eastern two-thirds of the contiguous United States were evaluated as an example to demonstrate the methodology. It is found that the HRRR model was able to forecast convective storm characteristics rather well either as .
The Pro-Fibrotic Response to Lens Injury Is Signaled in a PI3K Isoform-Specific Manner

The signaling inputs that function to integrate biochemical and mechanical cues from the extracellular environment to alter the wound-repair outcome to a fibrotic response remain poorly understood. Here, using a clinically relevant post-cataract surgery wound healing/fibrosis model, we investigated the role of Phosphoinositide-3-kinase (PI3K) class I isoforms as potential signaling integrators to promote the proliferation, emergence and persistence of collagen I-producing alpha smooth muscle actin (αSMA+) myofibroblasts that cause organ fibrosis. Using PI3K isoform specific small molecule inhibitors, our studies revealed a requisite role for PI3K p110α in signaling the CD44+ mesenchymal leader cell population that we previously identified as resident immune cells to produce and organize a fibronectin-EDA rich provisional matrix and transition to collagen I-producing αSMA+ myofibroblasts. While the PI3K effector Akt was alone insufficient to regulate myofibroblast differentiation, our studies revealed a role for Rac, another potential PI3K effector, in this process. Our studies further uncovered a critical role for PI3K p110α in signaling the proliferation of CD44+ leader cells, which is important to the emergence and expansion of myofibroblasts. Thus, these studies identify activation of PI3K p110α as a critical signaling input following wounding to the development and progression of fibrotic disease.
