description: Eesmärk. Teha kindlaks uurimistulemuste esitamisel kasutatavate arvjooniste ja arvjooniseliikide sagedus ning kvaliteet epidemioloogiaajakirjades. Meetodid. Kolme epidemioloogiaajakirja (American Journal of Epidemiology, European Journal of Epidemiology, Paediatric and Perinatal Epidemiology) 2010. aasta numbritest valiti välja 187 algupäraste uuringute tulemusi kajastavat artiklit. Tehti kindlaks nendes esitatud arvjooniste ja arvjooniseliikide arv. Iga arvjoonise kvaliteeti – s.o visuaalset selgust, arvulist moonutatust, iseenesestmõistetavust, risustatust ja mõnda muud tunnust – hinnati R. J. Cooperi jt (2001, 2002, 2003) ning D. L. Schrigeri jt (2006) metoodika alusel. Tulemused. Valitud artiklitest sisaldas arvjooniseid 50%, kokku oli avaldatud 184 arvjoonist. Sagedamini kasutati joondiagrammi (38%), püst- ja rõhttulpdiagrammi (27%), punktdiagrammi (15%), elulemuskõverat ja hajuvusdiagrammi (kumbagi 5%). Üldse ei leidnud kasutamist karp- ega sektordiagramm. Veatuid arvjooniseid oli 10%. Põhilised eksimused olid iseenesestmõistetavuse (56%) ja visuaalse selguse (42%) puudumine, arvuline moonutus (39%) ja liigsete andmete esitamine (27%). Järeldused. Ehkki viimaste aastakümnete jooksul on tohutult paranenud andmetöötlusvoõmalused ja uurimustes kasutatavate arvjooniste koostamise põhimotteid käsitletud küllaldase selgusega, avaldatakse palju mannetuid jooniseid. Peame ülimalt soovitatavaks lisada arvjoonistele esitatavate üksikasjalike nõuete loetelu kõigisse juhendmaterjalidesse, mis puudutavad teadustöö tulemuste esitamist ajakirjades, raportites, magistri- ja doktoritöödes.

description: Coordination of distributed energy resources is critical for electricity grid management. Although nodal pricing schemes can mitigate congestion and voltage deviations, the resulting prices are not necessarily equitable. In this work, we leverage market mechanisms for DER coordination and propose a daily dynamic nodal pricing scheme that incorporates equity. We introduce a pricing "oracle," which we call the Power Distribution Authority, that sets equitable prices to manage the grid. We present two algorithms for executing this scheme and show that both methods are able to set prices that satisfy both voltage and equity constraints. Both proposed algorithms also outperform the common utility time-of-use pricing schemes by at least 45%. New market mechanisms are needed as the grid is transforming, and power system operators may leverage these methods for pricing electricity in a grid-aware, equitable fashion.

The effects of water level changes on the limnology of two British Columbia coastal lakes with particular reference to the bottom fauna
Creators: name: Sinclair, Donald Coll
Publisher: name: University of British Columbia
Year: 2011

description: In the summer of 1964 a study was carried out on the impounded Buttle and Lower Campbell Lakes located on Vancouver Island, British Columbia. An attempt was made to determine the effects of increased water level fluctuation on the limnology, particularly the bottom fauna, in areas with different substrate types. All data from two pre-impoundment studies were examined, and additional sampling carried out to provide a basis for comparison. In addition, several stations were chosen in each lake according to specific substrate types. These different bottom conditions were formed from the combined effects of erosion by water level fluctuation and wave action, over areas where different methods of pre-impoundment clearing of vegetation had been employed. The stations chosen were the shallow onshore areas which were exposed to the air during the winter months of minimum water level, the unexposed area immediately below the minimum drawdown level, and the pre-impoundment littoral zones in each study lake. A single pre-impoundment river channel station was located in Buttle Lake. In addition to bottom dredgings, funnel traps and nocturnal surface tows were used to sample the emerging insect fauna from each station. The total seasonal chironomid catch indicated significantly different total emergence between the several stations sampled. The pre-impoundment river station in Buttle Lake produced the highest total chironomid catch. Among the other stations the unexposed area immediately below the drawdown level was most productive. In Buttle Lake where the greatest seasonal fluctuation occurred and where the completely cleared littoral area was least protected from wave action, the total seasonal emergence over the exposed littoral area was very low. But in Lower Campbell Lake which received a much smaller seasonal water level fluctuation, total emergence was much higher over the exposed littoral. This area was cleared completely in this lake and the irregular shoreline afforded considerable protection from wind action. An inverted bathymetric distribution of the fauna was apparent with the greatest concentration occurring immediately below the drawdown limit in the unexposed littoral zone. The effects of water level changes were therefore considered the most important single factors influencing the bottom fauna distribution in each lake.

description: Though Multimodal Sentiment Analysis (MSA) proves effective by utilizing rich information from multiple sources (e.g., language, video, and audio), the potential sentiment-irrelevant and conflicting information across modalities may hinder the performance from being further improved. To alleviate this, we present Adaptive Language-guided Multimodal Transformer (ALMT), which incorporates an Adaptive Hyper-modality Learning (AHL) module to learn an irrelevance/conflict-suppressing representation from visual and audio features under the guidance of language features at different scales. With the obtained hyper-modality representation, the model can obtain a complementary and joint representation through multimodal fusion for effective MSA. In practice, ALMT achieves state-of-the-art performance on several popular datasets (e.g., MOSI, MOSEI and CH-SIMS) and an abundance of ablation demonstrates the validity and necessity of our irrelevance/conflict suppression mechanism.

description: The last decade has seen enormous progress in understanding the structure of the Milky Way and neighboring galaxies via the production of large-scale digital surveys of the sky like 2MASS and SDSS, as well as specialized, counterpart imaging surveys of other Local Group systems. Apart from providing snaphots of galaxy structure, these "cartographic" surveys lend insights into the formation and evolution of galaxies when supplemented with additional data (e.g., spectroscopy, astrometry) and when referenced to theoretical models and simulations of galaxy evolution. These increasingly sophisticated simulations are making ever more specific predictions about the detailed chemistry and dynamics of stellar populations in galaxies. To fully exploit, test and constrain these theoretical ventures demands similar commitments of observational effort as has been plied into the previous imaging surveys to fill out other dimensions of parameter space with statistically significant intensity. Fortunately the future of large-scale stellar population studies is bright with a number of grand projects on the horizon that collectively will contribute a breathtaking volume of information on individual stars in Local Group galaxies.

title: Economics of Land Use Planning: A Case Study of Annexation in Heber Valley, Utah
Creators: name: Summers, Lyle C.
Publisher: name: Utah State University
Year: 1975

description: Some theories and methodologies applicable to land use planning problems were reviewed along with the history of land use and land use legislation in the United States and Utah. This review served to point out that federal land use policy is moving away from the incentive approach to controlling land use and toward a more mandatory approach aimed at giving increased emphasis to environmental quality and less to economic efficiency.
A model for conceptualizing and analyzing annexation problems was developed and applied to a problem in Heber City, Wasatch County, Utah. The analysis demonstrated that annexation is feasible by showing net beneficial effects for the macro area. The model displays the analytical data in a way that enables planners and decision makers to see who gains, who loses, and the approximate amounts of the gains and losses. Thus the decision makers are able to determine who must be compensated and by how much in order to accomplish an improvement in welfare under the Pareto criteria.

IPF on peamiselt eakamatel isikutel (> 50 a) esinev keskmise levimusega haigus (20–50 juhtu 100 000 inimese kohta), mille levik organismis piirdub kopsudega ning mille radioloogiliseks ja patohistoloogiliseks leiuks on nn tavaline interstitsiaalne pneumoonia (UIP). Diagnoos kinnitatakse enamikul juhtudest iseloomuliku kliinilis-radioloogilise leiu alusel (UIP-leid) ja muude sarnast leidu andvate seisundite välistamisel. IPFi on viimase aastakümne vältel varasemaga võrreldes oluliselt paremini tundma õpitud. Varasem eksperdiarvamustel, mõnel väikesemahulisel uuringul ja üldisel ravimise soovil põhinenud soovitus ravida haigust prednisolooni, asatiopriini või tsüklofosfamiidi ja N-atsetüültsüsteiiniga (nn kolmikravi) on osutunud pigem kahjulikuks. Nende asemele on tulnud antifibrootilise toimega ravim pirfenidoon, kuid käimas on veel suur hulk uuringuid teiste võimalike IPFi ravimikandidaatidega, mille hulgas leidub monoklonaalseid antikehi tsütokiinide, integriinide ja kasvufaktorite vastu, samuti kasvufaktorite retseptoritega seotud türosiini kinaasi inhibiitoreid.

description: The elderly population is vulnerable to air pollution due to low mobility and high prevalence of chronic disorders. There is an urgent need to improve air quality of elderly care centres (ECCs), yet quantitative research on this topic is limited. This thesis aims to find appropriate solutions to mitigate exposure to air pollution in and around ECCs by: (1) synthesising potential air pollution mitigation options to improve air quality inside and outside ECCs; (2) examining the role of roadside green infrastructure in improving air quality in and around ECCs in heavily-trafficked cities; (3) evaluating effective ventilation design measures to improve air quality in ECC two-bed bedrooms; (4) assessing ventilation and air quality of densely occupied multi-purpose rooms; (5) exploring the cooperation of cooker hood and baffle designs to reduce pollutant build-up in elderly’s kitchens. This study used portable monitors to collect air quality data and proposed various models for computational fluid dynamics simulations. It quantitatively analysed airflow, air pollutant distribution, pollutant removal effectiveness, air change efficiency, mean age of air, predicted mean vote, capture efficiency, intake fraction, hazard ratio, and energy saving. The key findings are: (1) ECC should be located away from busy roads and near green areas to reduce exposure to vehicle emissions; (2) Implementing air outlets near pillows, inlets on the wall opposite beds, and installing curtains between beds enhances air quality in two-bed bedrooms while preserving resident’s privacy; (3) In densely occupied multi-purpose rooms, placing air outlets on both sides of walls at sitting breathing height and inlets evenly distributed on ceiling significantly enhances air quality without disrupting residents' activities or work of staff; (4) Installing at least 100 mm baffles on cooker hood both sides and front can greatly reduce elderly's air pollution exposure, without hindering cooking activities. This is the first study to examine ECC air quality improvement, considering characteristics of the elderly and their living environment. The thesis provided a comprehensive air pollution exposure assessment for elderly people living in ECCs across multiple environments (cooking, sleeping, event areas, and outdoors).

description: Classes with bounded expansion, which generalise classes that exclude a topological minor, have recently been introduced by Nešetřil and Ossona de Mendez. These classes are defined by the fact that the maximum average degree of a shallow minor of a graph in the class is bounded by a function of the depth of the shallow minor. Several linear-time algorithms are known for bounded expansion classes (such as subgraph isomorphism testing), and they allow restricted homomorphism dualities, amongst other desirable properties. In this paper we establish two new characterisations of bounded expansion classes, one in terms of so-called topological parameters, the other in terms of controlling dense parts. The latter characterisation is then used to show that the notion of bounded expansion is compatible with Erdös-Rényi model of random graphs with constant average degree. In particular, we prove that for every fixed $d>0$, there exists a class with bounded expansion, such that a random graph of order $n$ and edge probability $d/n$ asymptotically almost surely belongs to the class. We then present several new examples of classes with bounded expansion that do not exclude some topological minor, and appear naturally in the context of graph drawing or graph colouring. In particular, we prove that the following classes have bounded expansion: graphs that can be drawn in the plane with a bounded number of crossings per edge, graphs with bounded stack number, graphs with bounded queue number, and graphs with bounded non-repetitive chromatic number. We also prove that graphs with `linear' crossing number are contained in a topologically-closed class, while graphs with bounded crossing number are contained in a minor-closed class.

description: Internationally there is growing evidence that family structure, and changes in structure, have an impact on children’s health and wellbeing and the intergenerational transmission of inequity. The effects, however, vary by socio-economic context and ethnicity. Using longitudinal data from Growing Up in New Zealand (n = 1349), we examine family structure and change for tamariki Māori during early childhood, and the potential impacts on their development and wellbeing. We find that a stable two-parent family is the primary experience for tamariki Māori, and sole parenthood is transitory. Diverse family trajectories appear to be linked to poorer cognitive and socioemotional outcomes but are not the main driver. More important are maternal factors, notably age and education, and material hardship. Importantly, higher levels of cultural connectedness among tamariki Māori, which are associated with diverse family forms, seem to promote socio-emotional development. Our study provides further incentive for policy and programmes that centre equity and support access to the determinants of health for tamariki Māori.

Haigus on tavaliselt asümptomaatiline, mistõttu diagnoosimine on sageli keeruline ja aeganõudev. Tihti jõutakse õige diagnoosini alles pärast kirurgilisel teel eemaldatud lümfisõlmede patohistoloogilist uurimist. Artiklis kirjeldatud 67aastase naispatsiendi juhtum on tüüpiline Castlemani tõve ühekoldelisele vormile. Patsient esitas ebamääraseid kaebusi, vereanalüüsid olid muutusteta ning radioloogilised uuringud (sonograafia, KT, MRT) ei viidanud konkreetsele haigusele. Kuna lisamass alakõhus viitas siiski tumoroossele haigusele, teostati kolde resektsioon. Castlemani tõve diagnoos kinnitati histoloogilisel uurimisel. Ühekoldelise Castlemani  haiguse puhul, nagu kirjeldatud juhul, on kirurgiline ravi kuratiivne ja haige ei vaja edasist adjuvantravi.

description: We investigate the tetraquark bound states that are manifestly exotic using three distinct few-body methods: Gaussian Expansion Method (GEM), Resonating Group Method (RGM), and Diffusion Monte Carlo (DMC). We refer to manifestly exotic states that do not involve a mixture with the conventional mesons through the creation and annihilation of $n\bar{n}$, where $n=u, d$. Our calculations are conducted with two types of quark models: the pure constituent quark model featuring one-gluon-exchange interactions and confinement interactions, and the chiral constituent quark model, supplemented by extra one-boson-exchange interactions. This study represents a comprehensive benchmark test of various few-body methods and quark models. Our findings reveal the superiority of GEM over RGM and DMC methods based on present implements for the tetraquark bound states. Additionally, we observe a tendency for the chiral quark model to overestimate the binding energies. We systematically explore the fully, triply, doubly, and singly heavy tetraquark states with $J^P=0^+,1^+,2^+$, encompassing over 150 states in total. We successfully identify several bound states, including $[cc\bar{n}\bar{n}]_{J^{P}=1^{+}}^{I=0}$, $[bb\bar{n}\bar{n}]_{J^{P}=1^{+}}^{I=0}$, $[bc\bar{n}\bar{n}]_{J^{P}=0^{+},1^{+},2^{+}}^{I=0}$, $[bs\bar{n}\bar{n}]_{J^{P}=0^{+},1^{+}}^{I=0}$, $[cs\bar{n}\bar{n}]_{J^{P}=0^{+}}^{I=0}$, and $[bb\bar{n}\bar{s}]_{J^{P}=1^{+}}$, all found to be bound states below the dimeson thresholds.

description: Using as ingredients the non-perturbative solutions of various QCD Green's function obtained from Schwinger-Dyson equations (SDEs), we study two versions of the QCD effective charge. The first one obtained from the pinch technique gluon self-energy, and the second from the ghost-gluon vertex. Despite the distinct nature of their buildings blocks, the two effectives charges are almost identical in the entire range of momenta, due to a fundamental identity relating the ghost dressing function with the two form factors of Green's function, which is of central importance in the PT-BFM formalism. In this talk, we outline how to derive this crucial identity from the SDEs of the aforementioned Green's functions. The renormalization procedure that preserves the validity of this identity is discussed in detail. Most importantly, we show that due to the infrared finiteness of the gluon propagator, the QCD charge obtained with either definition freezes in the deep infrared, in agreement with theoretical and phenomenological expectations.

description: Detection of a gravitational-wave stochastic background via ground or space-based gravitational-wave detectors requires the cross-correlation of the response of two or more independent detectors. The cross-correlation involves a frequency-dependent factor -- the so-called overlap reduction function or Hellings-Downs curve -- that depends on the relative geometry of each detector pair: i.e., the detector separations and the relative orientation of their antenna patterns (beams). An incorrect formulation of this geometrical factor has appeared in the literature, leading to incorrect conclusions regarding the sensitivity of proposed detectors to a stochastic gravitational-wave background. To rectify these errors and as a reference for future work we provide here a complete, first-principles derivation of the overlap reduction function and assess the nature of the errors associated with the use of the incorrect expression that has appeared in the literature. We describe the behavior of the overlap reduction function in different limiting regimes, and show how the difference between the correct and incorrect expressions can be understood physically.

Ka Eesti Vabariigi teaduspoliitika üheks olulisemaks arenguks  viimastel aastatel on olnud  teaduse  tippkeskuste  süsteemi  loomine  ja  konkreetsete  tippkeskuste nimetamine. Selle tulemusena on Tartu Ülikooli arstiteaduskonna pinnalt võrsunud kaks  tippkeskust: erinevatel  institutsioonidel  tuginev Eesti  käitumis-  ja terviseteaduste  keskus ning ainult arstiteaduskonna struktuuriüksustest moodustunud molekulaarse  ja kliinilise meditsiini keskus.

title: Microbial Bioassay Techniques for Assessing Acid Mine Spoil Amendments for Revegetation
Creators: name: Anderson, Michael A.
Publisher: name: Utah State University
Year: 1976

description: The revegetation of sterile acid mine spoils is a costly and lengthy process due to the many factors (pH, toxic materials, low nutrients, poor soil structure, temperature, moisture, length of growing season, etc.) which impede the establishment of stable plant communities . A microbial bioassay technique applied to soil systems has been developed to allow a rapid (four weeks) and integrated (with respect to nutrients and toxicants) determination of the best amendments for stabilizing mine spoils by revegetation. Using mine spoil from the Blackbird Mine, Cobalt (near Salmon), Idaho, various comb illations of nitrogen, phosphorus, chelators, trace elements, potassium, manure and salt leaching were studied with the bioassay by observing microscopically and by measuring nitrogen fixation and accumulation, dehydrogenase activity, chlorophyll a accumulation, and other chemical parameters.
It was concluded that the limiting factors for microbial (algal) growth were, in order of importance, pH control, soil moisture, and phosphorus. Other treatments failed to show statistically significant better results over the control. The fate of phosphorus in the spoil and its effect on growth response kinetics is also speculatively discussed.

description: In recent years, depth sensors have become more and more affordable and have found their way into a growing amount of robotic systems. However, mono- or multi-modal sensor registration, often a necessary step for further processing, faces many challenges on raw depth images or point clouds. This paper presents a method of converting depth data into images capable of visualizing spatial details that are basically hidden in traditional depth images. After noise removal, a neighborhood of points forms two normal vectors whose difference is encoded into this new conversion. Compared to Bearing Angle images, our method yields brighter, higher-contrast images with more visible contours and more details. We tested feature-based pose estimation of both conversions in a visual odometry task and RGB-D SLAM. For all tested features, AKAZE, ORB, SIFT, and SURF, our new Flexion images yield better results than Bearing Angle images and show great potential to bridge the gap between depth data and classical computer vision.

description: We combine data from the MGC, SDSS and UKIDSS LAS surveys to produce ugrizYJHK luminosity functions and densities from within a common, low redshift volume (z<0.1, ~71,000 h_1^-3 Mpc^3 for L* systems) with 100 per cent spectroscopic completeness. In the optical the fitted Schechter functions are comparable in shape to those previously reported values but with higher normalisations (typically 0, 30, 20, 15, 5 per cent higher phi*-values in u, g, r, i, z respectively over those reported by the SDSS team). We attribute these to differences in the redshift ranges probed, incompleteness, and adopted normalisation methods. In the NIR we find significantly different Schechter function parameters (mainly in the M* values) to those previously reported and attribute this to the improvement in the quality of the imaging data over previous studies. This is the first homogeneous measurement of the extragalactic luminosity density which fully samples both the optical and near-IR regimes. Unlike previous compilations that have noted a discontinuity between the optical and near-IR regimes our homogeneous dataset shows a smooth cosmic spectral energy distribution (CSED). After correcting for dust attenuation we compare our CSED to the expected values based on recent constraints on the cosmic star-formation history and the initial mass function.

title: The Effects of Chemical and Cultural Treatments on Gibberellin Levels in Strawberry Leaves and on the Induction of Secondary Flowering
Creators: name: Arteca, Richard N.
Publisher: name: Utah State University
Year: 1976

description: Gibberellins 3, 4 and 7 were isolated from "Shasta" Strawberry (Fragaria X ananassa Duch.) leaves and identified by gas and thin layer chromatography. In young expanding leaves GA3 occurred at 5 times the concentration of either GA4 or GA7.
CCC (2-chloroethyl-trimethylammonium chloride), SADH (Succinamic acid-2,2-dimethyl hydrazide), ethephon (2-chloroethylphosphonic acid), and UBI-P293 (2,3-dihydro-5-6-diphenyl-1,4-oxathiin) were applied to established plantings of three June-bearing strawberry (Fragaria X ananassa Ouch.) cultivars: 11 Shasta, 11 "Fresno" and "Tioga." Treatments were applied on alternate days for three weeks following anthesis of the king blossom. Levels of GA3 and GA4 were reduced by all treatments, but GA7 occurred at such low concentrations that treatment effects could not be measured statistically. Three weeks' exposure to short-daylengths (8 hours of light and 16 hours of darkness) resulted in no change in GA3 or GA7, but GA4 concentrations were significantly reduced . Leaf tissue was analyzed t o e valuate treatment effects on chlorophyll content; no significant changes were observed. No secondary flowering as a result of photoperiod , post-harvest defoliation or growth retardant treatments was observed.

description: We study the propagation of a scalar, the trace of $h_{ij}$ in the deformed Hořava-Lifshitz gravity with coupling constant $λ$. It turns out that this scalar is not a propagating mode in the Minkowski spacetime background. In this work, we do not choose a gauge-fixing to identify the physical degrees of freedom and instead, make it possible by substituting the constraints into the quadratic Lagrangian.

title: Effects of Forced Exercise on Fertility, Parturition, Mammary Edema, Feed Consumption, and Milk Production in Two-Year-Old Holstein Dairy Heifers
Creators: name: Barker, Brent O.
Publisher: name: Utah State University
Year: 1976

description: Forty-two springer Holstein heifers were grouped in threes by sire, body weight, and due date. One of each group served as a control (no exercise). One of each group was exercised at 5.5 kilometers per hour for 1.6 kilometers per day, 5 days per week beginning 4 weeks before expected calving date . The third member of each group was exercised the same as the second member, but exercise was continued for 10 days after calving. Exercise was in a circular lane with a motor driven gate. Prepartum exercise increased ease of parturition and reduced the length of time from calving to release of the placenta. Exercise resulted in smaller uterine horn diameters at 42 days postpartum, but had no significant effect on measures of fertility such as days open or services per conception . Exercise did not appear to reduce severity of udder edema, but edema was first noticeable in control heifers. Milk production for the first 50 days after calving showed no affect from prepartum exercise, but continuing exercise after calving reduced milk production 2.4 kg per day (P< .05). Grain was fed according to production, hence grain consumption was also significantly lower for the postpartum exercise group. Hay consumption for the prepartum exercise group was significantly lower than for controls. Prepartum exercise significantly increased feed utilization efficiency as compared to postpartum exercise.
Static Hopfions in the extended Skyrme-Faddeev model

description: We construct static soliton solutions with non-zero Hopf topological charges to a theory which is an extension of the Skyrme-Faddeev model by the addition of a further quartic term in derivatives. We use an axially symmetric ansatz based on toroidal coordinates, and solve the resulting two coupled non-linear partial differential equations in two variables by a successive over-relaxation (SOR) method. We construct numerical solutions with Hopf charge up to four, and calculate their analytical behavior in some limiting cases. The solutions present an interesting behavior under the changes of a special combination of the coupling constants of the quartic terms. Their energies and sizes tend to zero as that combination approaches a particular special value. We calculate the equivalent of the Vakulenko and Kapitanskii energy bound for the theory and find that it vanishes at that same special value of the coupling constants. In addition, the model presents an integrable sector with an infinite number of local conserved currents which apparently are not related to symmetries of the action. In the intersection of those two special sectors the theory possesses exact vortex solutions (static and time dependent) which were constructed in a previous paper by one of the authors. It is believed that such model describes some aspects of the low energy limit of the pure SU(2) Yang-Mills theory, and our results may be important in identifying important structures in that strong coupling regime.

title: The Anti-Thyroid Effects of Halogenated Phenols and Pyridinols
Creators: name: Beck, Leland Steven
Publisher: name: Utah State University
Year: 1976

description: This research was initiated to determine the mechanism(s) of action that could explain increased weight gain and decreased milk production i n dairy cattle fed corn silage containing residues of certain organophosphate pesticides. It was proposed that the mode of action involved and alteration of thyroid physiology by the metabolites of the pesticides, namely halogenated phenols. Studies were carried out to determine the effect of tri-halogenated phenols and pyridinols upon T4-binding to bovine serum albumin (BSA) and to liver mitochondria isolated from male rats. Using the rat as a model, feeding trials were performed to determine the effect of halogenated phenols and pyridinols on rate of gain, relative thyroid weight, thyroid histology, and serum- T 4 levels.
In vitro results with BSA indicated that the mechanism could have involved competition between T4 and the phenol for the T4 -binding site(s) of serum proteins, thus possibly lowering the serum-T4 level. This was not well substantiated by in vivo measurements of serum-T4 levels from rats fed varying concentrations of halogenated phenols.
The methods employed to determine the effect of halophenols upon r4 binding to mitochondria indicated that these compounds are poor competitors for the T4 -binding site on mitochondria. At the dose levels employed, there appeared to be no uniform dose response relationship between the various halogenated phenols and pyridinols and thyroid histology, relative thyroid weight and feed efficiency.

description: Stablecoins and central bank digital currencies are on the horizon in Asia, and in some cases have already arrived. This paper provides new analysis and a critique of the use case for both forms of digital currency. It provides time-varying estimates of devaluation risk for the leading stablecoin, Tether, using data from the futures market. It describes the formidable obstacles to widespread use of central bank digital currencies in cross-border transactions, the context in which their utility is arguably greatest. The bottom line is that significant uncertainties continue to dog the region's digital currency initiatives.

description: Artiklis on vaatluse alla võetud Eesti tööturu üks riskirühm – tervisehäirega töötajad – ning püütud analüüsida, kas nende olukord ja tingimused tööturul, aga samuti hinnangud tööalasele tulevikule erinevad millegi poolest tervete töötajate omast. Uurimuse aluseks on 2002. aasta Eesti tööjõu-uuringu andmestik, mis  sisaldas muu hulgas ka küsimusteplokki „tervis“. 13 663st 15–64aastasest vastanust väitis 22,7% ehk 3105 inimest, et neil on mõni pikaajaline haigus, puue või vaevus. Empiirilise materjali analüüs lubab väita, et tervisehäirega ja terved töötajad ei ole Eesti tööturul võrdses seisus: esimesed jäävad pea igas vaadeldud aspektis teistele alla. Erinevused ei ole küll suured, kuid nad on olemas.

description: We confirm the planetary nature of TOI-5344 b as a transiting giant exoplanet around an M0 dwarf star. TOI-5344 b was discovered with the Transiting Exoplanet Survey Satellite photometry and confirmed with ground-based photometry (the Red Buttes Observatory 0.6m telescope), radial velocity (the Habitable-zone Planet Finder), and speckle imaging (the NN-Explore Exoplanet Stellar Speckle Imager). TOI-5344 b is a Saturn-like giant planet ($ρ= 0.80^{+0.17}_{-0.15}\ \text{g cm}^{-3}$) with a planetary radius of $9.7 \pm \ 0.5 \ \text{R}_{\oplus}$ ($0.87 \pm \ 0.04 \ \text{R}_{\text{Jup}}$) and a planetary mass of $135^{+17}_{-18} \text{M}_{\oplus}$ ($0.42^{+0.05}_{-0.06} \ \text{M}_{\text{Jup}}$). It has an orbital period of $3.792622 \pm 0.000010$ days and an orbital eccentricity of $0.06^{+0.07}_{-0.04}$. We measure a high metallicity for TOI-5344 of [Fe/H] = $0.48 \pm 0.12$, where the high metallicity is consistent with expectations from formation through core accretion. We compare the metallicity of the M-dwarf hosts of giant exoplanets to that of M-dwarf hosts of non-giants ($\lesssim 8\ \text{R}_{\oplus}$). While the two populations appear to show different metallicity distributions, quantitative tests are prohibited by various sample caveats.
