description: Microcephaly and medulloblastoma may both result from mutations that compromise genomic stability. We report that ATR, which is mutated in the microcephalic disorder Seckel syndrome, sustains cerebellar growth by maintaining chromosomal integrity during postnatal neurogenesis. Atr deletion in cerebellar granule neuron progenitors (CGNPs) induced proliferation-associated DNA damage, p53 activation, apoptosis and cerebellar hypoplasia in mice. Co-deletions of either p53 or Bax and Bak prevented apoptosis in Atr-deleted CGNPs, but failed to fully rescue cerebellar growth. ATR-deficient CGNPs had impaired cell cycle checkpoint function and continued to proliferate, accumulating chromosomal abnormalities. RNA-Seq demonstrated that the transcriptional response to ATR-deficient proliferation was highly p53 dependent and markedly attenuated by p53 co-deletion. Acute ATR inhibition in vivo by nanoparticle-formulated VE-822 reproduced the developmental disruptions seen with Atr deletion. Genetic deletion of Atr blocked tumorigenesis in medulloblastoma-prone SmoM2 mice. Our data show that p53-driven apoptosis and cell cycle arrest – and, in the absence of p53, non-apoptotic cell death – redundantly limit growth in ATR-deficient progenitors. These mechanisms may be exploited for treatment of CGNP-derived medulloblastoma using ATR inhibition.

description: One of the key issues in studying transcriptional regulation during development is how to employ genome-wide assays that reveals sites of open chromatin and transcription factor binding to efficiently identify biologically relevant genes and enhancers. Analysis of Drosophila CNS midline cell development provides a useful system for studying transcriptional regulation at the genomic level due to a large, well-characterized set of midline-expressed genes and in vivo validated enhancers. In this study, FAIRE-seq on FACS-purified midline cells was performed and the midline FAIRE data were compared with whole-embryo FAIRE data. We find that regions of the genome with a strong midline FAIRE peak and weak whole-embryo FAIRE peak overlap with known midline enhancers and provide a useful predictive tool for enhancer identification. In a complementary analysis, we compared a large dataset of fragments that drive midline expression in vivo with the FAIRE data. Midline enhancer fragments with a midline FAIRE peak tend to be near midline-expressed genes, whereas midline enhancers without a midline FAIRE peak were often distant from midline-expressed genes and unlikely to drive midline transcription in vivo.

description: The Multicolor Simultaneous Camera for studying Atmospheres of Transiting exoplanets (MuSCAT) is an optical three-band (g'_2-, r'_2-, and z_{s,2}-band) imager that was recently developed for the 188cm telescope at Okayama Astrophysical Observatory with the aim of validating and characterizing transiting planets. In a pilot observation with MuSCAT we observed a primary transit of HAT-P-14b, a high-surface gravity (g_p=38 ms^{-2}) hot Jupiter around a bright (V=10) F-type star. From a 2.9 hr observation, we achieved the five-minute binned photometric precisions of 0.028%, 0.022%, and 0.024% in the g'_2, r'_2, and z_{s,2} bands, respectively, which provided the highest-quality photometric data for this planet. Combining these results with those of previous observations, we search for variations of transit timing and duration over five years as well as variations of planet-star radius ratio (R_p/R_s) with wavelengths, but can find no considerable variation in any parameters. On the other hand, using the transit-subtracted light curves we simulate achievable measurement error of R_p/R_s with MuSCAT for various planetary sizes, assuming three types of host stars: HAT-P-14, the nearby K dwarf HAT-P-11, and the nearby M dwarf GJ1214. Comparing our results with the expected atmospheric scale heights, we find that MuSCAT is capable of probing the atmospheres of planets as small as a sub-Jupiter (R_p ~6 R_Earth) around HAT-P-14 in all bands, a Neptune (~4R_Earth) around HAT-P-11 in all bands, and a super-Earth (~2.5R_Earth) around GJ1214 in r'_2 and z_{s,2} bands. These results promise that MuSCAT will produce fruitful scientific outcomes in the K2 and TESS era.

description: This report is a detailed account of the key discussion points and findings of four participatory evaluation workshops with the ETHNA System implementing partners, internal and external stakeholders held online in September and October 2022. The main aim of this report is to collect the difficulties found in the implementation processes while looking for common and divergent points which will feed into the last evaluative and analytical tasks of the ETHNA project.
 The overarching goal of this series of workshops was to involve the participants in shaping the evaluation questions within the themes of the Living Labs, the methodology of the ETHNA Lab process and the ethical governance system ETHNA System. The workshops were organised as semi-structured events centred on these main themes, leaving great flexibility to pursue questioning and dialogue among participants. Furthermore, the participatory approach generated collective reflections on the insights and lessons learned from the ETHNA System implementation, as well as ethical governance as a whole. The workshops employed a diversity of exchange formats to support mutual learning and feedback gathering as needed. Some desirable results are recommendations to improve the ETHNA System implementation.

description: The use of weak measurements for performing quantum tomography is enjoying increased attention due to several recent proposals. The advertised merits of using weak measurements in this context are varied, but are generally represented by novelty, increased efficacy, and foundational significance. We critically evaluate two proposals that make such claims and find that weak measurements are not an essential ingredient for most of their advertised features.

description: The electronic and magnetic properties of monoclinic double perovskite Sr$_2$CeIrO$_6$ were examined based on both experiments and first-principles density functional theory calculations. From the calculations we conclude that low-spin-state Ir$^{4+}$ (5$\textit{d}^5$, S=$\frac{1}{2}$) shows t$_{2g}$ band derived anti-ferro type orbital ordering implying alternating occupations of $\textit{d}_{yz}$ and $\textit{d}_{xz}$ orbitals at the two symmetrically independent Ir sites. The experimentally determined Jahn-Teller type distorted monoclinic structure is consistent with the proposed orbital ordering picture. Surprisingly, the Ir-5$\textit{d}$ orbital magnetic moment was found to be $\approx$ 1.3 times larger than the spin magnetic moment. The experimentally observed AFM-insulating states are consistent with the calculations. Both electron-electron correlation and spin-orbit coupling (SOC) are required to drive the experimentally observed AFM-insulating ground state. This single active site double perovskite provides a rare platform with a prototype geometrically frustrated fcc lattice where among the different degrees of freedom (i.e spin, orbital, and lattice), spin-orbit interaction and Coulomb correlation energy scales compete and interact with each other.

description: Controlled cell division is central to the growth and development of all multicellular organisms. Within the proliferating zone of the Arabidopsis root, regular symmetric divisions give rise to patterns of parallel files of cells, the genetic basis of which remains unclear. We found that genotypes impaired in the TONNEAU1a (TON1a) gene display misoriented symmetric divisions in the epidermis and have no division defects in the underlying cortical tissue. The TON1a gene encodes a microtubule-associated protein. We show that in the ton1a mutant, epidermal and cortical cells do not form narrow, ring-like preprophase bands (PPBs), which are plant-specific, cytoskeletal structures that predict the position of the division plane before mitosis. The results indicate that in the cortex but not in the epidermis, division plane positioning and patterning can proceed correctly in the absence of both a functional TON1a and PPB formation. Differences between tissues in how they respond to the signals that guide symmetric division orientation during patterning might provide the basis for organised organ growth in the absence of cell movements.

description: This paper presents an evaluation of the provision of Ecosystem Services (ES). The analysis is based on the design of a framework suitable to be translated into a multi-criteria evaluation process, followed by empirical testing. It focuses on the different categories of ES and applies a set of non-overlapping indicators available from existing statistical sources. The framework is applied in a traditional cultural landscape, the Province of Ferrara, situated in the Emilia-Romagna region of Italy. To develop an applicable framework, we have chosen a set of ES indicators from the Millennium Ecosystem Assessment. According to the results and based on the indicators used in each category, the provision of cultural and provisioning services is high in all of the municipalities, while there is greater diversity in the provision of regulating and supporting services. A key challenge in our analysis was related to the lack of information on the actual provision of ES at the municipality level, which led to a significant use of proxy indicators. Use of improved datasets, explicit consideration of policy scenarios and accounting for local priorities about ES provision have been identified as the most relevant avenues for future research in this area.

description: Hormonal interactions are crucial for plant development. In Arabidopsis, cytokinins inhibit root growth through effects on cell proliferation and cell elongation. Here, we define key mechanistic elements in a regulatory network by which cytokinin inhibits root cell elongation in concert with the hormones auxin and ethylene. The auxin importer AUX1 functions as a positive regulator of cytokinin responses in the root; mutation of AUX1 specifically affects the ability of cytokinin to inhibit cell elongation but not cell proliferation. AUX1 is required for cytokinin-dependent changes of auxin activity in the lateral root cap associated with the control of cell elongation. Cytokinin regulates root cell elongation through ethylene-dependent and -independent mechanisms, both hormonal signals converging on AUX1 as a regulatory hub. An autoregulatory circuit is identified involving the control of ARR10 and AUX1 expression by cytokinin and auxin, this circuit potentially functioning as an oscillator to integrate the effects of these two hormones. Taken together, our results uncover several regulatory circuits controlling interactions of cytokinin with auxin and ethylene, and support a model in which cytokinin regulates shootward auxin transport to control cell elongation and root growth.

description: The Common Agricultural Policy (CAP) reform of 2014-2020 is characterized by a strong mandate of Member States regarding the 1st Pillar. This paper’s objective is to elucidate the possible impacts of Italian choices on direct payments and their coherence with the specific objectives of the CAP, which was established by the Expert Group on Monitoring and Evaluating the CAP (EGMEC): food security and sustainable food production. Thus, an online survey was disseminated among Italian CAP experts in the spring of 2015. The results from a sample of 25 respondents show that Italian direct payments may positively contribute to viable food production by improving agricultural competitiveness. In addition, the combined effect of general direct payment schemes and Italian choices is to ensure sustainable food provision or, at least, to successfully allow the exploration of this new route in CAP history, which most likely represents future challenge for European agriculture.

Accounting for growth in global agriculture
Creators: name: Fuglie, Keith
Publisher: name: Bio-based and Applied Economics
Year: 2015

description: Rising prices of agricultural commodities have renewed concerns about constraints to agricultural productivity. To assess productivity trends, total factor productivity (TFP) is generally preferred to partial productivity indexes as an indicator of technical and efficiency changes because it is more closely related to the unit costs of production. But measuring TFP is demanding of data, and developing comprehensive and comparable indexes of international agricultural TFP has been challenging. This study proposes a growth accounting approach, using FAO data on quantity changes in inputs and outputs and aggregating input changes using cost shares derived from other sources, as a consistent way of constructing agricultural TFP indexes for world agriculture. This produces aggregate growth rates for agricultural output, input and TFP at the country, regional and global levels. Results suggest that the rate of agricultural TFP growth accelerated in recent decades, especially in developing countries. Most regions of the world now rely on productivity-based growth rather than resource-based growth to raise agricultural output.

description: Nanomechanical and other mesoscopic vibrational systems typically have several nonlinearly coupled modes with different frequencies and with long lifetime. We consider the power spectrum of one of these modes. Thermal fluctuations of the modes nonlinearly coupled to it lead to fluctuations of the mode frequency and thus to the broadening of its spectrum. However, the coupling-induced broadening is partly masked by the spectral broadening due to the mode decay. We show that the mode coupling can be identified and characterized using the change of the spectrum by weak resonant driving. We develop a path-integral method of averaging over the non-Gaussian frequency fluctuations from nonresonant (dispersive) mode coupling. The shape of the driving-induced power spectrum depends on the interrelation between the coupling strength and the decay rates of the modes involved. The characteristic features of the spectrum are analyzed in the limiting cases. We also find the power spectrum of a driven mode where the mode has internal nonlinearity. Unexpectedly, the power spectra induced by the intra- and inter-mode nonlinearities are qualitatively different. The analytical results are in excellent agreement with the numerical simulations.

Several interesting relations are derived between the real and imaginary parts of $_2F_1$ and the function $H_4$.

description: Oral epithelia protect against constant challenges by bacteria, viruses, toxins and injury while also contributing to the formation of ectodermal appendages such as teeth, salivary glands and lingual papillae. Despite increasing evidence that differentiation pathway genes are frequently mutated in oral cancers, comparatively little is known about the mechanisms that regulate normal oral epithelial development. Here, we characterize oral epithelial stratification and describe multiple distinct functions for the mitotic spindle orientation gene LGN (Gpsm2) in promoting differentiation and tissue patterning in the mouse oral cavity. Similar to its function in epidermis, apically localized LGN directs perpendicular divisions that promote stratification of the palatal, buccogingival and ventral tongue epithelia. Surprisingly, however, in dorsal tongue LGN is predominantly localized basally, circumferentially or bilaterally and promotes planar divisions. Loss of LGN disrupts the organization and morphogenesis of filiform papillae but appears to be dispensable for embryonic hair follicle development. Thus, LGN has crucial tissue-specific functions in patterning surface ectoderm and its appendages by controlling division orientation.

The previous reservation on the key rate and suitability of DV-MDI-QKD for metropolitan networks expressed by Pirandola et al. [Nature Photon. 9, 397 (2015)] was based on an unfair comparison with low-efficiency detectors and high quantum bit error rate, and is, in our opinion, unjustified.

description: The development of the vertebrate embryonic heart occurs by hyperplastic growth as well as the incorporation of cells from tissues outside of the initial heart field. Amongst these tissues is the epicardium, a cell structure that develops from the precursor proepicardial organ on the right side of the septum transversum caudal to the developing heart. During embryogenesis, cells of the proepicardial organ migrate, adhere and envelop the maturing heart, forming the epicardium. The cells of the epicardium then delaminate and incorporate into the heart giving rise to cardiac derivatives, including smooth muscle cells and cardiac fibroblasts. Here, we demonstrate that the LIM homeodomain protein Lhx9 is transiently expressed in Xenopus proepicardial cells and is essential for the position of the proepicardial organ on the septum transversum. Utilizing a small-molecule screen, we found that Lhx9 acts upstream of integrin-paxillin signaling and consistently demonstrate that either loss of Lhx9 or disruption of the integrin-paxillin pathway results in mis-positioning of the proepicardial organ and aberrant deposition of extracellular matrix proteins. This leads to a failure of proepicardial cell migration and adhesion to the heart, and eventual death of the embryo. Collectively, these studies establish a requirement for the Lhx9-integrin-paxillin pathway in proepicardial organ positioning and epicardial formation.

description: Blood vessel formation is essential for vertebrate development and is primarily achieved by angiogenesis – endothelial cell sprouting from pre-existing vessels. Vessel networks expand when sprouts form new connections, a process whose regulation is poorly understood. Here, we show that vessel anastomosis is spatially regulated by Flt1 (VEGFR1), a VEGFA receptor that acts as a decoy receptor. In vivo, expanding vessel networks favor interactions with Flt1 mutant mouse endothelial cells. Live imaging in human endothelial cells in vitro revealed that stable connections are preceded by transient contacts from extending sprouts, suggesting sampling of potential target sites, and lowered Flt1 levels reduced transient contacts and increased VEGFA signaling. Endothelial cells at target sites with reduced Flt1 and/or elevated protrusive activity were more likely to form stable connections with incoming sprouts. Target cells with reduced membrane-localized Flt1 (mFlt1), but not soluble Flt1, recapitulated the bias towards stable connections, suggesting that relative mFlt1 expression spatially influences the selection of stable connections. Thus, sprout anastomosis parameters are regulated by VEGFA signaling, and stable connections are spatially regulated by endothelial cell-intrinsic modulation of mFlt1, suggesting new ways to manipulate vessel network formation.

description: Quantum speed limit (QSL) time for open systems driven by classical fields is studied in the presence of thermal bosonic environments. The decoherence process is quantitatively described by the time-convolutionless master equation. The evolution speed of an open system is related not only to the strength of driving classical field but also to the environmental temperature. The energy-state population plays a key role in the thermal QSL. Comparing with the zero-temperature reservoir, we predict that the structural reservoir at low temperatures may contribute to the acceleration of quantum decoherence. The manifest oscillation of QSL time takes on under the circumstance of classical driving fields. We also investigate the scaling property of QSL time for multi-particle noninteracting entangled systems. It is demonstrated that entanglement of open systems can be considered as one resource for improving the potential capacity of thermal quantum speedup.

description: A current goal of molecular biology is to identify transcriptional networks that regulate cell differentiation. However, identifying functional gene regulatory elements has been challenging in the context of developing tissues where material is limited and cell types are mixed. To identify regulatory sites during sex determination, we subjected Sertoli cells from mouse fetal testes to DNaseI-seq and ChIP-seq for H3K27ac. DNaseI-seq identified putative regulatory sites around genes enriched in Sertoli and pregranulosa cells; however, active enhancers marked by H3K27ac were enriched proximal to only Sertoli-enriched genes. Sequence analysis identified putative binding sites of known and novel transcription factors likely controlling Sertoli cell differentiation. As a validation of this approach, we identified a novel Sertoli cell enhancer upstream of Wt1, and used it to drive expression of a transgenic reporter in Sertoli cells. This work furthers our understanding of the complex genetic network that underlies sex determination and identifies regions that potentially harbor non-coding mutations underlying disorders of sexual development.

Intergenerational continuity in high-conflict family environments

description: Abstract In the current study, we examined continuity in conflict across generations and explored potential mediators and moderators that could explain this continuity. We followed 246 targets from adolescence to adulthood and examined family conflict as reported by multiple reporters in targets' family of origin and current families. Results showed that conflict in the current family was strongly correlated with that of the family of origin in women but not in men. Continuity in family conflict across generations was mediated by patterns of elevated adolescent externalizing behavior in members of the second generation (G2). In addition, analyses revealed an interaction between both G2 partners' externalizing behavior such that if one partner in the G2 family demonstrated high levels of externalizing behavior, elevated levels of family conflict resulted. Potential explanations and implications of these findings are considered.
A study of principal instructional leadership behaviors manifested in successful and nonsuccessful urban elementary schools

description: The purpose of the study was to discover the principal instructional leadership behaviors differed in successful and nonsuccessful urban elementary schools. Six schools were selected and paired according to size, ethnicity, socioeconomic status, and attendance to discover the salient leadership behavior differences between and among them. A descriptive survey research design was utilized to collect data through the Hallinger-Murphy Principal Instructional Management Rating Scale (PIMRS) which assessed frequency of leadership behaviors. Six (100%) of the principals and 95 (49%) teachers responded. The research questions were tested statistically using Analysis of Variance to decipher leadership differences between the pairs of schools and differences of perceived principal behaviors based on teachers' grade levels and teaching experience. The instructional leadership behaviors manifested by the principals in the selected schools were identified through the PIMRS and tested using the .05 confidence level as the measure of significance. The current literature reported that higher frequency of leadership behaviors, such as those identified in the PIMRS, could lead to academically successful schools. The results of this study went against the grain of the current literature since high scores on the PIMRS did not ensure successful schools and provided confoundment rather than clarification. The principals in the paired schools showed few differences in job behavior patterns, yet one school in each pair was academically successful; the other was not. The research questions stated: 1) There are significant differences between the instructional leadership behaviors demonstrated by the principals of schools with high student achievement when compared with the principals of schools with low student achievement; 2) student demographic characteristics (ethnicity, attendance of students, socioeconomic status) influence student success; and 3) there is a difference in teachers' perceptions of principals' instructional leadership behaviors based on their years of teaching experience and grade level taught. The first and third questions were rejected since the data in this study did not support the questions. The second question was not statistically tested due to a lack of difference in the student populations in the schools. Further study and testing of the Ballinger-Murphy Model is required in order to draw final conclusions on the relationship between principal instructional leadership behaviors and student achievement

Stellar and Gaseous Disk Structures in Cosmological Galaxy Equilibrium Models

description: We present "radially-resolved-equilibrium-models" for the growth of stellar and gaseous disks in cosmologically accreting massive halos. Our focus is on objects that evolve to redshifts $z\sim 2$. We solve the time-dependent equations that govern the radially dependent star-formation rates, inflows and outflows from and to the inter- and circum-galactic medium, and inward radial gas flows within the disks. The stellar and gaseous disks reach equilibrium configurations on dynamical time scales much shorter than variations in the cosmological dark matter halo growth and baryonic accretions rates. We show analytically that mass and global angular momentum conservation naturally give rise to exponential gas and stellar disks over many radial length scales. As expected, the gaseous disks are more extended as set by the condition Toomre $Q<1$ for star-formation. The disks rapidly become baryon dominated. For massive, $5\times 10^{12}M_\odot$ halos at redshift $z=2$, we reproduced the typical observed star-formation rates of $\sim 100 \, M_\odot \, {\rm yr}^{-1}$, stellar masses $\sim 9\times 10^{10}\, M_\odot$, gas contents $\sim 10^{11}\, M_\odot$, half mass sizes of 4.5 and 5.8 kpc for the stars and gas, and characteristic surface densities of $500$ and $ 400\, M_\odot \, {\rm pc}^{-2}$ for the stars and gas.

description: Abstract Poor physiological self-regulation has been proposed as a potential biological vulnerability for adolescent suicidality. This study tested this hypothesis by examining the effect of parasympathetic stress responses on future suicide ideation. In addition, drawing from multilevel developmental psychopathology theories, the interplay between parasympathetic regulation and friendship support, conceptualized as an external source of regulation, was examined. At baseline, 132 adolescent females ( M age = 14.59, SD = 1.39) with a history of mental health concerns participated in an in vivo interpersonal stressor (a laboratory speech task) and completed self-report measures of depressive symptoms and perceived support within a close same-age female friendship. Respiratory sinus arrhythmia (RSA) was measured before and during the speech task. Suicide ideation was assessed at baseline and at 3, 6, and 9 months follow-up. The results revealed that females with greater relative RSA decreases to the laboratory stressor were at higher risk for reporting suicide ideation over the subsequent 9 months. Moreover, parasympathetic responses moderated the effect of friendship support on suicide ideation; among females with mild changes or higher relative increases in RSA, but not more pronounced RSA decreases, friendship support reduced risk for future suicide ideation. Findings highlight the crucial role of physiological and external regulation sources as protective factors for youth suicidality.
