Optimism is in the air as we turn to face a new calendar year. As far as residential real estate goes, there is plenty to feel positive about.

This document provides a summary of the 2010 PEST MANAGEMENT UPDATE Forages, Pastures, and Invasive Plants from the University of Wisconsin-Madison. It discusses new herbicide labels for use in pastures and forages, techniques for controlling winter annual weeds in alfalfa, establishing legumes after herbicide application, and managing herbicide persistence in manure to avoid impacting sensitive crops. The document also provides resources on identifying and managing invasive plant species according to Wisconsin's new invasive species rule.
Legume establishment after herbicides 2010weedscience
This document summarizes three studies from 2006-2009 on the impact of fall-applied herbicides on legume establishment the following spring in Wisconsin. Across the studies, herbicide applications of Milestone and Ally in the fall sometimes reduced legume establishment the next year, depending on application date and rate, planting date, soil temperature, and planting method. The conclusion is that if legumes are critical, it is better to spot treat rather than broadcast apply herbicides in the fall and wait until late summer or the following spring to plant.
This document discusses weed management in alfalfa. Weeds can reduce alfalfa establishment, yield, and forage quality. The critical period for weed removal is 3-5 weeks after planting. Herbicides like Pursuit and Raptor can be used during establishment with some potential yield loss. Roundup Ready alfalfa allows post-emergence glyphosate applications with more flexible timing but has higher seed and technology costs. Weed management is important to secure stand establishment and provide high quality forage, especially in the first cutting. Management options depend on weed species, density, and field conditions.

The document summarizes an experiment comparing the performance of GraphQL and REST APIs when querying data from MongoDB and ElasticSearch databases. The key findings are:
1) Optimizing queries between the client and application server had less impact than expected, with GraphQL responses being smaller but not significantly faster.
2) Optimizing queries between the application server and databases showed more significant performance gains, with projections in GraphQL and optimized database queries improving speeds.
3) GraphQL's ability to optimize queries from client to data storage is an advantage, but it should not be chosen primarily for performance reasons alone. Further testing is needed to evaluate performance for specific use cases.
This document discusses the importance of communicating design decisions to stakeholders. It notes that design can be subjective and intuitive, making it difficult to explain decisions to others. The key message is that communicating the rationale for design work will become more important than the design itself. It provides principles for design communication, including identifying problems, describing solutions, empathizing with users, appealing to business needs, and securing agreement. Overall it argues that explaining design choices is critical and one of the biggest failures is the illusion that communication has already occurred.

This document summarizes the development of a community seed bank in Arakan Valley, Philippines in 2007. It describes the objectives of establishing the seed bank, which were to monitor preferred rice varieties and ensure farmers have access to seeds. A total of 177 community seed bank farms were established across 15 barangays. The farms grew 12 upland rice varieties, with Dinorado and UPL Ri-5 being most common. Most farmers applied fertilizers and pesticides. Germination rates were mixed but tillering capacity was generally good. Farmers evaluated varieties positively and intended to replant selections.
Herbicide-resistant rice varieties were developed to help control weeds like weedy rice through the use of herbicides. While this can help in the short term, overuse may lead to herbicide resistance in weeds and reduce sustainability of rice production. Proper stewardship measures like crop rotations and preventing seed spread are needed to reduce risks. The document calls on government, research and private groups to work together on developing good stewardship guidelines for herbicide-resistant rice in Asia.

SDSS1335+0728: The awakening of a ∼ 106M⊙ black hole⋆Sérgio Sacani
Context. The early-type galaxy SDSS J133519.91+072807.4 (hereafter SDSS1335+0728), which had exhibited no prior optical variations during the preceding two decades, began showing significant nuclear variability in the Zwicky Transient Facility (ZTF) alert stream from December 2019 (as ZTF19acnskyy). This variability behaviour, coupled with the host-galaxy properties, suggests that SDSS1335+0728 hosts a ∼ 106M⊙ black hole (BH) that is currently in the process of ‘turning on’. Aims. We present a multi-wavelength photometric analysis and spectroscopic follow-up performed with the aim of better understanding the origin of the nuclear variations detected in SDSS1335+0728. Methods. We used archival photometry (from WISE, 2MASS, SDSS, GALEX, eROSITA) and spectroscopic data (from SDSS and LAMOST) to study the state of SDSS1335+0728 prior to December 2019, and new observations from Swift, SOAR/Goodman, VLT/X-shooter, and Keck/LRIS taken after its turn-on to characterise its current state. We analysed the variability of SDSS1335+0728 in the X-ray/UV/optical/mid-infrared range, modelled its spectral energy distribution prior to and after December 2019, and studied the evolution of its UV/optical spectra. Results. From our multi-wavelength photometric analysis, we find that: (a) since 2021, the UV flux (from Swift/UVOT observations) is four times brighter than the flux reported by GALEX in 2004; (b) since June 2022, the mid-infrared flux has risen more than two times, and the W1−W2 WISE colour has become redder; and (c) since February 2024, the source has begun showing X-ray emission. From our spectroscopic follow-up, we see that (i) the narrow emission line ratios are now consistent with a more energetic ionising continuum; (ii) broad emission lines are not detected; and (iii) the [OIII] line increased its flux ∼ 3.6 years after the first ZTF alert, which implies a relatively compact narrow-line-emitting region. Conclusions. We conclude that the variations observed in SDSS1335+0728 could be either explained by a ∼ 106M⊙ AGN that is just turning on or by an exotic tidal disruption event (TDE). If the former is true, SDSS1335+0728 is one of the strongest cases of an AGNobserved in the process of activating. If the latter were found to be the case, it would correspond to the longest and faintest TDE ever observed (or another class of still unknown nuclear transient). Future observations of SDSS1335+0728 are crucial to further understand its behaviour. Key words. galaxies: active– accretion, accretion discs– galaxies: individual: SDSS J133519.91+072807.4

Evidence of Jet Activity from the Secondary Black Hole in the OJ 287 Binary S...Sérgio Sacani
Wereport the study of a huge optical intraday flare on 2021 November 12 at 2 a.m. UT in the blazar OJ287. In the binary black hole model, it is associated with an impact of the secondary black hole on the accretion disk of the primary. Our multifrequency observing campaign was set up to search for such a signature of the impact based on a prediction made 8 yr earlier. The first I-band results of the flare have already been reported by Kishore et al. (2024). Here we combine these data with our monitoring in the R-band. There is a big change in the R–I spectral index by 1.0 ±0.1 between the normal background and the flare, suggesting a new component of radiation. The polarization variation during the rise of the flare suggests the same. The limits on the source size place it most reasonably in the jet of the secondary BH. We then ask why we have not seen this phenomenon before. We show that OJ287 was never before observed with sufficient sensitivity on the night when the flare should have happened according to the binary model. We also study the probability that this flare is just an oversized example of intraday variability using the Krakow data set of intense monitoring between 2015 and 2023. We find that the occurrence of a flare of this size and rapidity is unlikely. In machine-readable Tables 1 and 2, we give the full orbit-linked historical light curve of OJ287 as well as the dense monitoring sample of Krakow.
Microbial interaction
Microorganisms interacts with each other and can be physically associated with another organisms in a variety of ways.
One organism can be located on the surface of another organism as an ectobiont or located within another organism as endobiont.
Microbial interaction may be positive such as mutualism, proto-cooperation, commensalism or may be negative such as parasitism, predation or competition
Types of microbial interaction
Positive interaction: mutualism, proto-cooperation, commensalism
Negative interaction: Ammensalism (antagonism), parasitism, predation, competition
I. Mutualism:
It is defined as the relationship in which each organism in interaction gets benefits from association. It is an obligatory relationship in which mutualist and host are metabolically dependent on each other.
Mutualistic relationship is very specific where one member of association cannot be replaced by another species.
Mutualism require close physical contact between interacting organisms.
Relationship of mutualism allows organisms to exist in habitat that could not occupied by either species alone.
Mutualistic relationship between organisms allows them to act as a single organism.
Examples of mutualism:
i. Lichens:
Lichens are excellent example of mutualism.
They are the association of specific fungi and certain genus of algae. In lichen, fungal partner is called mycobiont and algal partner is called
II. Syntrophism:
It is an association in which the growth of one organism either depends on or improved by the substrate provided by another organism.
In syntrophism both organism in association gets benefits.
Compound A
Utilized by population 1
Compound B
Utilized by population 2
Compound C
utilized by both Population 1+2
Products
In this theoretical example of syntrophism, population 1 is able to utilize and metabolize compound A, forming compound B but cannot metabolize beyond compound B without co-operation of population 2. Population 2is unable to utilize compound A but it can metabolize compound B forming compound C. Then both population 1 and 2 are able to carry out metabolic reaction which leads to formation of end product that neither population could produce alone.
Examples of syntrophism:
i. Methanogenic ecosystem in sludge digester
Methane produced by methanogenic bacteria depends upon interspecies hydrogen transfer by other fermentative bacteria.
Anaerobic fermentative bacteria generate CO2 and H2 utilizing carbohydrates which is then utilized by methanogenic bacteria (Methanobacter) to produce methane.
ii. Lactobacillus arobinosus and Enterococcus faecalis:
In the minimal media, Lactobacillus arobinosus and Enterococcus faecalis are able to grow together but not alone.
The synergistic relationship between E. faecalis and L. arobinosus occurs in which E. faecalis require folic acid
JAMES WEBB STUDY THE MASSIVE BLACK HOLE SEEDSSérgio Sacani
The pathway(s) to seeding the massive black holes (MBHs) that exist at the heart of galaxies in the present and distant Universe remains an unsolved problem. Here we categorise, describe and quantitatively discuss the formation pathways of both light and heavy seeds. We emphasise that the most recent computational models suggest that rather than a bimodal-like mass spectrum between light and heavy seeds with light at one end and heavy at the other that instead a continuum exists. Light seeds being more ubiquitous and the heavier seeds becoming less and less abundant due the rarer environmental conditions required for their formation. We therefore examine the different mechanisms that give rise to different seed mass spectrums. We show how and why the mechanisms that produce the heaviest seeds are also among the rarest events in the Universe and are hence extremely unlikely to be the seeds for the vast majority of the MBH population. We quantify, within the limits of the current large uncertainties in the seeding processes, the expected number densities of the seed mass spectrum. We argue that light seeds must be at least 103 to 105 times more numerous than heavy seeds to explain the MBH population as a whole. Based on our current understanding of the seed population this makes heavy seeds (Mseed > 103 M⊙) a significantly more likely pathway given that heavy seeds have an abundance pattern than is close to and likely in excess of 10−4 compared to light seeds. Finally, we examine the current state-of-the-art in numerical calculations and recent observations and plot a path forward for near-future advances in both domains.
