A Systematic Review and Meta-Analysis of Creep Feeding Effects on Piglet Pre- and Post-Weaning Performance

Simple Summary In pig production, nursing piglets are frequently offered a highly palatable and easily digestible diet (creep feed). Creep feeding is believed to increase the weaning weight of piglets and to facilitate a smooth transition from sow’s milk to the dry feed. However, the research results are conflicting, and this might be due to the fact that several factors can impact the positive aspects of creep feeding during lactation. Therefore, the aim of the present study was to evaluate the effects of creep feeding on piglet pre- and post-weaning performance. Our results demonstrated that providing piglets with creep feed in lactation increases piglet body weight at weaning and post-weaning growth performance. We also identified that a minimum of 14 days of creep feed provision is necessary to realize a higher body weight at weaning. Abstract In the present systematic review and meta-analysis, we evaluated the effects of providing piglets with creep feed during lactation on piglet pre- and post-weaning performance. A total of 20 articles met the inclusion criteria. Creep feeding in lactation improved pre-weaning piglet performance in 46% of the studies selected, while 58% of the included studies reported that creep feeding in lactation improved piglet performance during the nursery phase. Creep feeding increased the average piglet body weight (creep = 7.23 ± 0.30, no creep = 6.96 ± 0.31; p = 0.03) and litter weight (creep = 81.2 ± 4.18, no creep = 76.4 ± 4.22; p < 0.001) at weaning. The average piglet body weight and litter weight were positively associated (p < 0.001 and p < 0.001, respectively) with total creep feed intake. Creep feeding of piglets for more than 14 days increased (p = 0.003) the litter weight at weaning compared to litters not provided or provided for shorter periods with creep feed. The present work strengthened the notion that creep feeding during lactation presents opportunities for improving weaning weights and post-weaning piglet performance compared to litters not provided or provided for shorter periods with creep feed.
Corporate Governance Stability And its Impact on the Quality of Accounting Information of Companies Listed on the Iraq Stock Exchange

Purpose: This research attempts to examine the influence of corporate governance stability on the accounting information quality. Theoretical framework: Stability in different mechanisms of corporate governance can help companies develop coherent plans and strategies and achieve their goals. Multitudinous changes in factors such as ownership and management and monitoring institutions such as independent auditors and members of audit committee can make changes in the company's goals thus affecting the financial reporting quality as a means of accountability of corporate governance elements. Methodology: The stability of corporate governance was measured using four criteria, namely managerial stability, ownership stability, independent audit tenure stability, and audit committee tenure stability. The statistical population includes the companies admitted to the Iraq Stock Exchange, and the research sample has been selected by the application of the conditions of the study variables to 55 companies in 2011 and 2020. In order to analyze the data and test the hypotheses, the statistical technique of multiple regression with panel data has been used. Finding: This work shows that the first hypothesis is rejected and that the managerial stability is negatively correlated with the accounting information quality. Moreover, according to the results, the second hypothesis of the research is also rejected and ownership stability is negatively correlated with the quality of accounting information. The third hypothesis outcomes also indicate the rejection of the research hypothesis and the independent auditor tenure stability and the accounting information quality have a similar relationship. Accordingly, the audit committee tenure stability is not significantly correlated with the accounting information quality. Research, Practical & Social implications: The results of testing the hypotheses showed that the greater the stability in the governance and monitoring elements of companies, the lower the quality of accounting information. Originality/value: Prior studies have focused on one or more corporate governance criteria and measured their impact on the accounting information quality. It should be noted that none of the conducted studies have provided a model to identify the impact of corporate governance on the accounting information quality.
A Candidate for an Intrinsic Dusty Absorber with a Metal-rich Damped Lyα Absorption Line System in the Quasar J170542.91+354340.2

We present a detailed analysis of the unusual damped Lyα absorption line system (DLA) toward the quasar SDSS J170542.91+354340.2 at a redshift of 2, previously reported by Noterdaeme et al. as one of the very few CO absorbers known to date at high z. This DLA is exceptional in that: (1) its extinction curve is similar to peculiar Milky Way sightlines penetrating star formation regions; (2) its absorption components are redshifted at a speed of several hundred km s−1 compared to broad Balmer emission lines; (3) its gas-phase metallicity is super-solar as evaluated from more than 30 absorption lines; (4) detection of residual flux in the DLA trough and variability of absorption is possible. Based on these facts, we argue that this dusty DLA is a good candidate for an intrinsic quasar 2175 Å absorber, and can originate from star formation regions of the quasar’s host galaxy. We discuss in detail the gas and dust properties, and the dust depletion. Follow-up observations, such as spectropolarimetry and optical/infrared spectroscopy, will help to confirm the system’s intrinsic nature and to explore how dust grains behave in the extreme environments proximate to quasars.

Analysis of dynamics variation against thixotropic parameter’s preferential range

Variation in the dynamics of a steady-state blood ﬂow through a stenosed tapered artery has been investigated corresponding to changes in thixotropic parameter λ over the range [0,1]. To probe the role of parameter λ and diﬀerentiate the current model from other known non-Newtonian models, expressions of axial velocity, shear stress, wall shear stress and ﬂow rate have been calculated depending upon this parameter and pressure gradient. Also, pressure gradient has been deduced uniquely with the help of the continuity equation. Our choice of calculating pressure gradient has led to obtaining shear stress such that its dependence on the structural parameter of our model, unlike most available results, motivates for further investigation. The simul- taneous eﬀects of varying yield stress and parameter λ on axial velocity, ﬂow resistance and ﬂow rate have been studied such that the diﬀerences between the Herschel–Bulkley ﬂuid model and our current model can be pointed out. To validate the suitability of our model and some results in history, we have also obtained limiting results for particular values of λ .

Customized Real-Time Interior-Point Methods for Onboard Powered-Descent Guidance

This paper presents a new onboard-implementable, real-time convex optimization-based powered-descent guidance algorithm for planetary pinpoint landing. Earlier work provided the theoretical basis of convexification, the equivalent representation of the fuel-optimal pinpoint landing trajectory optimization problem with nonconvex control constraints as a convex optimization problem. Once the trajectory optimization problem is convexified, interior-point method algorithms can be used to solve the problem to global optimality. Though having this guarantee of convergence motivated earlier convexification results, there were no real-time interior point method algorithms available for the computation of optimal trajectories on flight computers. This paper presents the first such algorithm developed for onboard use and flight-tested on a terrestrial rocket with the NASA Jet Propulsion Laboratory and the NASA Flight Opportunities Program in 2013. First, earlier convexification results are summarized and the result.
Plant Growth Regulators and Activated Charcoal Selectively Affect Phenylethanoid and Flavone Glycoside Accumulation in Sideritis scardica Griseb. Tissue Culture

Sideritis scardica Griseb. is a Balkan endemic species traditionally used for the treatment of pulmonary emphysema and angina pectoris. Recent research has also shown its phytotherapeutic potential as an anticancer and neuroprotective agent. These findings, as well as the endangered status of the species in its wild habitats, have motivated the present research on application of plant cell tissue and organ culture for the purposes of both valuable germplasm conservation and secondary metabolites production. Shoot cultures of the plant were initiated from sterile germinated seeds and the effects of activated charcoal (AC), as well benzyl adenine and 1-naphthaleneacetic acid treatments, were experimented. The phenolic profile analysis was performed by HPLC/DAD/MSn. Comparison with samples collected from wild plants in their natural habitat was performed. It was established that in vitro multiplication induced by plant growth regulators (PGRs) was accompanied by a higher impairment of leaf morphology and trichome formation, as well as by the occurrence of plantlet hyperhydricity and callus formation, as compared with the AC treatments. Shoot culture-derived plant material was shown to produce two phenylethanoids and five flavone glycosides, not detected in the wild collected plant material. In addition, the two types of in vitro culture treatments led to the stimulation of either flavone glycosides or phenylethanoids in the in vitro cultivated plants. Thus, AC stimulated, to a higher extent, flavone glycosides’ accumulation, leading to an elevated flavone/phenylethanoid ratio, as compared with PGR treatments.
Chai Pride: Using LGBTQIA+ Jewish Identities to Understand Intersectionality in Public Administration

Research on intersectionality in public administration reveals the diversity of marginalized groups and provides greater understanding of the ways intersecting identities influence inter- and intra-communal relationships. This article highlights the nuances that exist at the intersection of LGBTQIA+ and Jewish identities and how intersectionality can inform public service and engagement with minoritized populations in public and nonprofit organizations. The authors use LGBTQIA+ Jewish communities to construct four tenets of intersectionality—multiple and mutually constitutive identities, dynamic processes in managing multiple identities, discrimination within identities, and intersectional organizations—and discuss their relevance to public administration.
Deformations of Harmonic Tori in S^3

In this thesis we investigate the topology of the moduli space of spectral data of harmonic maps from the torus into the 3-sphere. Harmonic tori in the 3sphere are in bijective correspondence with their spectral data, which consists of an algebraic curve (called a spectral curve), a pair of differentials, and a line bundle. Deformations of the spectral data correspond to deformations of the tori themselves. There are two classes of deformations; isospectral deformations vary only the line bundle, whereas non-isospectral deformations change the spectral curve itself. This thesis explores the latter. We use the theory of Whitham deformations to show that the moduli space of spectral data is a surface. For spectral curves of genus zero and one, the global topology of the moduli space is treated through explicit parametrisation. We enumerate the path connected components and show them to be simply connected, and prove that the moduli space of these adjacent spectral genera connect to one another in an appropriate limit.

Hyperspectral unmixing-based anomaly detection

Research supporting improved anomaly detection performance benefits a wide range of technical applications, and thus, the definition of what anomalies are and the subsequent means to detect them are wide ranging. In this treatment, an overview of the development of an anomaly detection approach based on spectral signatures obtained with hyperspectral unmixing is presented. The algorithm is designed to address some of the shortcomings of current techniques whose functionality is dependent upon normalized differences between discrete frequencies or spectral components, or those based on estimated distances between background spectra and pixels under test. Details about the extracted endmembers and their use for effective anomaly detection will be presented as well as, some thoughts on the expected requirements for future machine learning based implementations.
Frequency response of electrolyte-gated graphene electrodes and transistors

The interface between graphene and aqueous electrolytes is of high importance for applications of graphene in the field of biosensors and bioelectronics. The graphene/electrolyte interface is governed by the low density of states of graphene that limits the capacitance near the Dirac point in graphene and the sheet resistance. While several reports have focused on studying the capacitance of graphene as a function of the gate voltage, the frequency response of graphene electrodes and electrolyte-gated transistors has not been discussed so far. Here, we report on the impedance characterization of single layer graphene electrodes and transistors, showing that due to the relatively high sheet resistance of graphene, the frequency response is governed by the distribution of resistive and capacitive circuit elements along the graphene/electrolyte interface. Based on an analytical solution for the impedance of the distributed circuit elements, we model the graphene/electrolyte interface both for the electrode and the transistor configurations. Using this model, we can extract the relevant material and device parameters such as the voltage-dependent intrinsic sheet and series resistances as well as the interfacial capacitance. The model also provides information about the frequency threshold of electrolyte-gated graphene transistors, above which the device exhibits a non-resistive response, offering an important insight into the suitable frequency range of operation of electrolyte-gated graphene devices.
The Diagnostic Performance of Tumor Stage on MRI for Predicting Prostate Cancer-Positive Surgical Margins: A Systematic Review and Meta-Analysis

Purpose: Surgical margin status in radical prostatectomy (RP) specimens is an established predictive indicator for determining biochemical prostate cancer recurrence and disease progression. Predicting positive surgical margins (PSMs) is of utmost importance. We sought to perform a meta-analysis evaluating the diagnostic utility of a high clinical tumor stage (≥3) on magnetic resonance imaging (MRI) for predicting PSMs. Method: A systematic search of the PubMed, Embase databases, and Cochrane Library was performed, covering the interval from 1 January 2000 to 31 December 2022, to identify relevant studies. The Quality Assessment of Diagnostic Accuracy Studies 2 method was used to evaluate the studies’ quality. A hierarchical summary receiver operating characteristic plot was created depicting sensitivity and specificity data. Analyses of subgroups and meta-regression were used to investigate heterogeneity. Results: This meta-analysis comprised 13 studies with 3924 individuals in total. The pooled sensitivity and specificity values were 0.40 (95% CI, 0.32–0.49) and 0.75 (95% CI, 0.69–0.80), respectively, with an area under the receiver operating characteristic curve of 0.63 (95% CI, 0.59–0.67). The Higgins I2 statistics indicated moderate heterogeneity in sensitivity (I2 = 75.59%) and substantial heterogeneity in specificity (I2 = 86.77%). Area, prevalence of high Gleason scores (≥7), laparoscopic or robot-assisted techniques, field strength, functional technology, endorectal coil usage, and number of radiologists were significant factors responsible for heterogeneity (p ≤ 0.01). Conclusions: T stage on MRI has moderate diagnostic accuracy for predicting PSMs. When determining the treatment modality, clinicians should consider the factors contributing to heterogeneity for this purpose.
The Concentration of Atmospheric Carbon Dioxide on the Summit of Mt. Fuji (3776m), Japan

The concentration of atmospheric CO2 was measured on the summit of Mt. Fuji, Japan by using a flask sampling method in October 1980 and by operating a system for continuous measurement in July to October 1981. The diurnal CO2 variation was scarcely found, but irregular variations with periods of 3 to 5 days usually appeared especially in July and August, reflecting the difference of air masses arrived at the observation site in association with synoptic-scale weather systems. The CO2 concentrations at Mt. Fuji were found to be very close to those in the middle troposphere over Japan by comparing with the results of aircraft measurements. A trend of secular increase in the atmospheric CO2 concentration was suggested even from our present results for the limited observational period in two successive years.
Ritz Vector Approach for Evaluating the Dynamic Properties of Structural Systems and Incabinet Spectra

YANG, JIANFENG. Ritz Vector Approach for Evaluating the Dynamic Properties of Structural Systems and Incabinet Spectra. (Under the direction of Abhinav Gupta) The earthquake input needed in a shake table test for the seismic qualification of safety related electrical instruments, typically mounted on electrical cabinets or control panels, is defined in terms of incabinet response spectrum. This dissertation presents modifications to the originally proposed Ritz vector approach developed by Rustogi et al. (1998) for evaluating the dynamic properties of the cabinets and the incabinet spectra. Modifications are needed to overcome the limitations encountered in the application to actual cabinets. The accuracy of the modified formulations is evaluated by comparison of results for actual cabinets with the corresponding results obtained from detailed finite element analyses. The modified Ritz vector approach can account for actual rotational constraints imparted by supporting structural members such as stiffeners. It can also be applied to bench board type cabinets in which instruments are mounted on plates or frames that are inclined to the global axes as well as to frames in which parallel frame members can vibrate in different vibration shapes. In this dissertation, detailed finite element analyses are used to study the rocking behavior of cabinets and to show that accurate representation of the boundary conditions at the cabinet base is essential in the evaluation of cabinet rocking mode. Simple formulations are developed for evaluating the rocking stiffness in three different types of cabinet mounting arrangements. These formulations enable incorporation of a cabinet rocking mode in the Ritz vector approach. The Ritz vector approach is also used to develop new formulations for evaluating static and dynamic characteristics of rectangular slabs with edge beams. The effect of elastic edge restraints is considered by including appropriate integrals for edge beams in the expressions for total kinetic and potential energies in a Rayleigh-Ritz approach. The effect of various types of boundary conditions at the beam ends is accounted for by considering the corresponding Ritz vectors. The contribution of beam mass to the total kinetic energy is also considered in the proposed approach.
