Scots Pine, Control of Spring Generation Crawlers of a Pine Needle Scale, Carroll Co., OH, 1983
Authors: Nielsen David G.
Published: March 2022

Pinus sylvestris (2.5 to 3 m high) growing in an abandoned block of Christmas trees were chosen for evaluating toxicity of candidate insecticides against spring crawlers. Trees heavily infested with newly hatched crawlers were sprayed 20 May, using a KWH backpack mistblower operating at maximum rph to deliver ca 700 ml of finished spray to three sides of four, single-tree replicates per treatment. Skies were sunny with 21°C temperature and winds gusting to 24 kph. The strong wind gusts precluded application to the downwind side of the trees. All crawlers had hatched and were settled first instars when treatments were applied. Treatment effectiveness was evaluated 26 to 27 May by collecting infested needle fascicles from the middle of the sprayed portion of each tree. Fascicles were placed in coin envelopes and transported under refrigeration to the laboratory where the viability of the first 100 nymphs observed under a dissecting scope was determined. Counts were always made from at least three fascicles.
Scots Pine, Efficacy of Insecticides Against European Pine Sawfly, Carroll Co., Oh, 1983
Authors: Nielsen D. G. , Dunlap M. J.
Published: March 2022

Pinus sylvestris (ca. 1 m high) growing in a Christmas tree plantation were used for evaluating toxicity of candidate insecticides against medium-sized larvae (ca. 6 to 7 mm long). Infested trees were sprayed 13 May, using a KWH backpack mistblower operaing at 0.5 throttle and setting 3, for 15 sec to deliver 300 ml of finished spray to each of four, single-tree replicates per treatment. Ambient temperature was 23°F, with sunny skies and only a slight breeze. Treatment effectiveness was evaluated by counting the number of colonies per tree and estimating the number of larvae in each of the first four colonies detected. Treatments were first evaluated 16 May, followed by further inspection of Dimilin-treated trees on 20 and 24 May.

Authors: Nielsen D. G. , Dunlap M. J.
Published: March 2022

A heavily infested block of 30 to 38 cm taxus growing in old Lake Erie soil were chosen for evaluating the potential of spring drenches to kill large larvae before pupation. A watering can was used to apply 1.9 liters of finished material to 61 by 305 cm plots containing infested plants on 4 May under sunny skies at 10 to 13°C with strong winds. Treatments were replicated 6 times in a completely random design. Even distribution was attempted by using a slow flow rate and covering the treatment area with several passes of the watering can. Larval head capsules varied from 0.96 to 1.72 mm on the date of application. Treatment effectiveness was evaluated on 2 and 8 Jun., by counting the number of living larvae and pupae in standard-size (20 by 20 cm) root balls on two plants per plot. The root ball was placed over a large plastic tray with shallow sides and shaken vigorously until all soil was dislodged.

Direct-Contact Toxicity of 17 Candidate Insecticides, 1981-82
Authors: Vardell Henry H. , McDonald L. L. , Zettler J. L.
Published: March 2022

The insects used in this test were T. confusum adults 7 to 14 days old and A. megatoma larvae 3 to 5 months old. The insects were reared and tested in rooms maintained at 27 ± 1°C and 60 ± 5% RH. The candidate compounds were prepared as acetone solutions at concentrations calculated so that 0.5 μ1 would result in dosages of 0.4, 0.8, or 1.6 micrograms per insect when applied topically. However, one compound (SD 12211) was tested at 0.35 and 0.7 ug per insect. The insects were anesthetized with CO2 in a Buchner funnel for periods not to exceed 5 min. The immobilized insects were then held individually with a small suction tube and the insecticde applied to the dorsal surface of the thorax with an automatic microapplicator. Forty insects of each species were treated at each dosage level. The same number was treated with acetone as controls. Malathion-treated insects, at the same dosages, were used as the standard for comparison. After treatment the insects were placed into clean containers for post-treatment observation. The percentages of insects knocked down (KD) or dead plus moribund (D+M) were determined for T. confusum after 24 and 120 h and for A. megatoma at 24 and 3 36 h postexposure.
Flushing Activity of Insecticides Against the German Cockroach, 1981
Authors: Bennett G. W. , Runstrom E. S.
Published: March 2022

The test sites consisted of low-income housing units located in Indianapolis, Ind. Treatments were randomly assigned to each apartment before inspection. Evaluation areas within the test site consisted of the kitchen in general, cabinetry, refrigerator, and utility area. Infestations of each area were estimated by researchers using the visual count method. The number of cockroaches seen generally around the room was counted, then each possible harborage area was closely examined. The count for each site was considered to be the sum number of cockroaches counted throughout the site at the time of pretreatment. Test materials were applied to areas where pretreatment counts were made. All applications were applied as a normal cockroach cleanout procedure would demand (i.e., cracks and crevices, baseboards, beneath and behind sinks, stoves and refrigerators, around plumbing intersections of shelves and walls). Quantitative information in flushing activity was collected by visual counts of cockroaches in the general kitchen vicinity 5 and 30 min after treatment. Each treatment was replicated 4 times.
Activity of Orthene Against the German Cockroach, 1981
Authors: Bennett G. W. , Runstrom E. S.
Published: March 2022

Two formulations of Orthene were investigated, CC-6109 (2.5E) and CC-4233 (85S). The 2.5E formulation was applied as a 1.0 and 0.75% spray whereas the 85S was applied only as a 1.0% spray. A Dursban 2E (0.25%) and Vaponite 2E (0.25%) standard was used for comparative purposes. Masonite panels cut to 1 ft2 (929 cm2) were treated and used as exposure surfaces. A spray apparatus (tower) equipped with a conveyor belt was used to apply the pesticide to insure uniform distribution on the panels. A stainless steel nozzle, Spraying Systems Tee-jet 8001, was used during application. The tower was calibrated such that the material was applied at the rate of 1 gal/1000 ft2 (3.78 ml/929 cm2). Freshly sprayed panels were placed in residual aging compartments until the time of their use. Bioassasys were conducted at 30 sec, 5 min, 30 min, 6 h, and 24 h. Test insects were exposed to panels aged 1 day, 1 week, and 1 month. After exposure, insects were removed from the treated surface and held in untreated containers for 48 h. Food and water were provided during the 48 h evaluation period. Mortality counts were made at 24 and 48 h. Abbott’s formula was used to determine the percent mortality for all replications. A total of five replications was used for each exposure period. Each replication consisted of 10 cockroaches, 5 males, and 5 females.
Efficacy of Several Formulations of Permethrin and Cypermethrin on the German Cockroach, 1981
Authors: Bennett G. W. , Runstrom E. S.
Published: March 2022

The contact toxicity of three formulations (WP, EC, and encapsulated) each of permethrin and cypermethrin was investigated to determine the most effective formulation and rate, the contact time required to produce mortality, and the residual activity up to 3 months against the German cockroach. Dilutions were prepared to produce rates of 0.25 and 0.125% for each of the formulations tested. Masonite panels cut to 1 ft2 (929 cm2) were treated. A spray tower apparatus with a mechanized conveyor belt was used to apply the treatments. A stainless steel nozzle, Spraying Systems Tee-jet 8001, was used during application. The tower was calibrated such that each treatment was applied at 1 gal/1,000 ft2 (3.78 ml/929 cm2). Treated panels were placed in storage compartments for aging. After treatment, German cockroaches were exposed to deposits aged 0 day, 2 weeks, and 1, 2, and 3 months. Three bioassays (lengths of exposures to treated surface) were conducted at each of the aging periods for each of the formulations tested. Bioassays ranged from 5 sec to 48 h and were determined prior to testing to delineate the critical time periods necessary to produce acceptable mortalities. After exposure, insects were removed from the treated surface and placed in untreated holding jars for 48 h. Food and water were provided. Mortality counts were made at 24 and 48 h. The average percent mortality for all replicates was determined using Abbott’s formula. Three replicates were used for each exposure period. Each replication consisted of 10 cockroaches, 5 males, and 5 females.
Screening of Acaricides for Control of One-Host Ticks, 1983
Authors: Drummond R. O.
Published: March 2022

Larvae of the cattle tick, Boophilusannulatus (Say), and the southern cattle tick, B. microplus (Canestrini), in colony at the Cattle Fever Tick Research Laboratory, Falcon Heights and Mission, Tex., and the tropical horse tick, Anocentor nitens (Neumann), and the winter tick, Dermacentor albipictus (Packard), in colony at Kerrville, Tex., are placed onto cattle. Engorged females that detach naturally are tested. Usually candidate compounds (technical materials) are formulated as emulsifiable concentrates containing 25% active ingredient (AI), 65% zylene, and 10% Triton X-100. Compounds not soluble in xylene are usually formulated (14.3% AI) in a 1:1 mixture of N-methyl-2-pyrrolidinone and the xylene, Triton X-100 combination. Commercial wettable powders or emulsifiable concentrates may be used. All formulations are mixed with water immediately before treatment. Acaricides are routinely tested at 1, 0.1, and 0.01% AI; the lesser concentrations are obtained by serial dilution of the 1% concentration. Prior to treatment, ticks are washed, dried, sorted into groups of 10, and weighed. For treatment, groups of ticks are placed into 20 to 25 ml of acaricide, which is stirred vigorously for 30 sec and then poured through a screen that retains the ticks. Drained ticks are placed on paper toweling to dry and held in 8-dram shell vials at 27±l°C and >80% RH for oviposition. After 2 to 3 weeks, the female ticks are discarded and the eggs are weighed and held for another 4 to 5 weeks when percentage hatch is estimated visually. Other groups of 10 ticks, which are dipped in an emulsion of 2.6% xylene and 0.4% Triton X-100 or the mixture of xylene, Triton X-100, and pyrrolidinone (equivalent to the 1% concentration of AI) and handled as treated ticks, are used as treated controls.

Authors: Herald P. , Knapp P.W.
Published: March 2022

Guardian (5% and 7.5%) and Ectrin (8%) ear tags were applied at the rate of 2/hd to cows and calves on 18 and 19 May for fly control evaluation. Two similar untreated herds served as controls. On 12 Rug. the Guardian treatments were terminated due to numerous lost tags. A new test was started 17 Aug. in which two of the previous Guardian treated herds were tagged with a new Guardian (7.5%) ear tag design; cows and calves were tagged as before. One previous Ectrin herd and 1 untreated herd were used to compare the efficacy of the new Guardian ear tag. Pace flies were counted on the face of each of 10 cows in each herd and the number of horn flies on 1 side of the same cows were estimated. The mean fly numbers for each treatment is reported.

Various insecticides and application methods were evaluated for face fly and horn fly control on beef cattle. May through Sep., 1983, in Montgomery Co., Va. Herds and treatments were as follows: (1) Ectiban ear tapes applied 24 May to 16 mixed breed heifers. Two tapes per animal were attached to existing identification tags. Monitored for 16 weeks. (2) Ectiban tail tapes applied 30 May to 2 separate herds (A and B) of 21 Angus cows with calves each. Each cow and calf received one tape each, attached above the tail switch. Herd A was monitored for 16 weeks, Herd B for 14 weeks. (3) Ectiban 5.7% EC and diesel fuel (1 pt/5 gal) applied to ca. 20 mixed breed cows with calves and one bull (Herd A), and 16 Limousin cows with calves (Herb B) by means of forced-use backrubbers and facerubbers. Treatments were established 25 May and 7 Jun. for Herds A and B, respectively. Two gal of the insecticide-fuel mixture were used to recharge the rubbers monthly. Both herds were monitored for 9 weeks. (4) Ectiban 0.25% dust applied to 56 mixed breed cows with calves and 2 bulls by means of a mineral feeder type applicator established 25 May. The applicator was recharged with dust as needed. Monitored for 12 weeks. (5) Permectrin 10% ear strips applied 24 May to 19 mixed breed heifers and 10 mixed breed steers; all animals received two strips each. Monitored for 8 weeks. (6) Standard Ectrin 8% ear tags applied 24 May to 70 Angus cows with calves and Hereford bulls. Each cow received two tags per animal, and calves received one. Monitored for 17 weeks. (7) Untreated control herd of 15 mixed breed cows with calves and 1 bull, monitored for 17 weeks. All herds were maintained in separate pastures, and all were situated within ca. 2 miles of each other. Weekly face fly and horn fly estimations were made by the same person on 10 adult animals per herd. Numbers of face flies were estimated on the face and head and horn flies on one side of each animal.

Authors: Drummond R.O.
Published: March 2022

White mice are infested ocularly with five newly hatched larvae of Cuterebra fontinella Clark. Two days later, female mice are weighed and treated orally with candidate insecticides usually formulated in Tween 20; male mice have a plastic collar placed around their necks to prevent grooming and their bodies are dipped into 80-200 ml of an emulsion of the candidate insecticide usually formulated as an EC in xylene (65 parts), Triton X-100 (10 parts) and AI (25 parts). Highest dosages are 100 mg/kg orally and 1% dermally. Four days later, mice are killed and bodies examined carefully for encapsulated larvae usually found in the inguinal region. Effectiveness is determined by comparing numbers of larvae in treated mice with numbers in untreated mice. Probit analysis is conducted with corrected percent-kill data.

Authors: Burts Everett
Published: March 2022

Twenty-yr-old Anjou pear trees were sprayed with handgund operating at 600 lb/in2 to evaluate candidate pesticides for control of pear psylla. Plots consisted of five single-tree replicates in randomized block design. Pear psylla densities were estaimated by counts of adults and nymphs at about 2-week intervals. Adults were counted on five beating-tray samples per rep. Nymphs were counted from 50-leaf samples per rep. Leaf samples consisted of proximal, distal and three evenly spaced leaves between from each of 10 terminal shoots. Leaves were brushed and resulting slides were examined under a dissecting microscope. Pear psylla honeydew russet was measured by examining 25-fruit samples at harvest. Damage was recorded according to US grade standards for winter pears. Firmness, soluble solid content and weight were also measured on the fruit.
Control of

Psoroptes

Mites on Rabbits, 1983
Authors: Wright F. C.
Published: March 2022

Rabbits infested with Psoroptescuniculi (Delafond), the ear canker mite, or P. ovis (Hering), the common scabies mite of sheep and cattle, were treated with various acaricides at different concentrations. All rabbits wore plastic collars to restrict grooming; both ears of each rabbit tested were at least half filled with canker and scabs. The acaricides were usually tested as technical materials formulated as emulsifiable concentrates (EC) in xylene:Triton X-100 (66:10) or as company formulations. Emulsions containing 0.5% (the highest concentration tested) were prepared in 25-ml volumes and administered as ear washes to the rabbits. Each ear was filled with test solution, held and massaged gently for 1 min. The outside of each ear and the area around the head and neck were swabbed with the test material. Control rabbits were treated with the appropriate solvent system in the same manner. At weekly intervals the ears of the treated rabbits were checked for live mites with an otoscope. If live mites could not be seen by 6 weeks (42 days), the ear canals were swabbed and the swabs examined for live mites with the aid of a dissecting microscope.

A 4-year-old orchard of Nectared, Ruby Grande, Harko nectarines and Early Redhaven and Elberta peaches was used in this test. Replicated four-tree blocks of each variety were used for both treatments and the check. Treatments were applied on 31 Mar. All plots were sprayed to the point of drip (400 to 500 gal/acre) with handguns at 400 to 500 lb/in2 . Evaluation was made by counting number of colonies for green peach aphid and the number of wilted terminals per tree for the peach twig borer.
Cranberry, Fruitworm Control, 1982
Authors: Brodel Charles F.
Published: March 2022

The test was conducted on a uniformly vined, 35-year-old section of State Bog in East Wareham, Mass. The experimental design was a randomized complete block with eight treatment plots replicated four times. Plots (15 by 7 ft) were separated within blocks by 5-ft pathways and between blocks by 10-ft pathways. Two postbloom applications were made on 21 and 29 July, with a 10-gal, powered ground sprayer delivering ca 0.6 gal/min at 50 lb/in2. All treatments were diluted to the rate of 400 gal/acre. A spray disc (4/64 inch orifice) and long distance nozzle tip allowed the applications to simulate those achieved commercially with overhead sprinkler systems. Difolatan was applied on 18 June, 8 and 27 July, to prevent infection by fruit rot organisms. Temperatures during July and Aug. were markedly below normal and precipitation was slightly below normal. During the 3rd week of Oct., berries from five randomly selected, square-foot areas within each plot were harvested by hand and frozen. These were later inspected for injury by A.vaccinii. Data transformed to arc sine of the square root of proportion were subjected to an analysis of variance.
Inorganic Bromide Residues in Olives After Quarantine Treatments with Methyl Bromide, 1981
Authors: Tebbets J. S. , Nelson H. D.
Published: March 2022

Four cultivars of olives were fumigated at 70°F with 99.5% methyl bromide (MB) gas at normal atmospheric pressure, and with different dosage and time combinations. The MB treatments were either approved for use or were pending approval for use as quarantine treatments against infestations of Mediterranean fruit fly in various fresh fruits and vegetables. Raw olives, without packaging materials, were placed inside 1-ft3 chambers. The load in each chamber was 16 ± 1 lb/ft3 by weight or 45 ± 5% by volume. Gas samples were taken throughout the fumigation period to determine MB gas concentrations in the chamber atmosphere. Concentration x time products (CT products) were then calculated. After fumigation, the olives were aerated in the chamber for 1 h. Samples of the raw olives were taken from control and treated lots and held for 24 h at 70°F. Following removal of the pits, the olives were analyzed for determination of inorganic bromide residues using a wet chemical method with accurate detection at 2 ppm or more. The remainder of each lot was commercially processed and canned as black ripe olives. The canned product was sampled at a later time and analyzed to determine the effect of the processing procedure on the original level of inorganic bromides. The juice from the canned olives was also analyzed. All control samples (both raw and processed) had less than 2 ppm inorganic bomides. Each treatment was able to be replicated only two times, and two samples per treatment were taken each time for residue analysis.

Published: March 2022

Tests were conducted in a commercial almond (3rd leaf) orchard in Livingston, Calif. Six treatments were replicated 10 times using a randomized complete block design. Each replicate consisted of an individual tree. Materials were applied to the trunk from the ground to the secondary branches with a Hudson hand-held sprayer on 29 June. All materials were applied at 9.4 gal of spray mixture per acre. Infestations were evaluated by counting the number of active feeding sites or frass piles per tree. Frass piles were removed after counting. On 19 July, 10 to 15 larvae were collected from trees outside the plot. All were identified as American plum borer.

Bayberry Whitefly Control on Lemons, 1982
Authors: Walker G. P. , Carman G. E. , Fappas J. L.
Published: March 2022

Plots were located in Irvine, Calif, and were three rows of trees; evaluations came from the middle row. Tree spacing was 14 by 22 ft. Experimental design was randomized block with three blocks. Trees were short (ca. 12 ft) and there was considerable overlap in the spray pattern from 2.5 to 5.5 ft above ground. Each treatment was evaluated by counting the number of adult whiteflies on eight terminals from each of five trees per plot. This test also evaluated the rates of Pounce as well as the inclusion of oil or Citrufilm (Helena Chemical Co., Memphis, Tenn.) and the transformed data (logx+1) were analysed by two-way analysis of variance (ANOVA) and Duncan’s multiple range test. Three unsprayed control plots were included in the experiment but not in the randomized complete block. They were located 10 rows away from the main experiment to prevent them from becoming a source of reinfestation to any of the insecticide treated plots and to avoid the effect of insecticide drift into the unsprayed plots. The precount, based on pooling samples from 826 terminals on 18 and 20 Oct. was 13.3 adults per terminal. At the time of the test, the whitefly adult population was in a period of natural decline so that by 7 weeks after insecticide application the unsprayed plots had the lowest populations. It is not certain if the cause of this decline was biological control, weather or some other factor(s). Significant interactions in ANOVA of the main effects confused the analysis on all but the 22 Nov. data so the data were evaluated by plotting the mean and standard error of each plot.

Density-dependent growth, which might influence the effects of fisheries on a population, is often ignored when management strategies are evaluated, mainly due to a lack of appropriate models readily available to be implemented. To improve on this, we investigated if somatic growth in Norwegian spring-spawning herring (Clupea harengus) depends on cohort density using a formulation of the von Bertalanffy growth function on cohorts from 1921 to 2014 and found a significant negative correlation between estimated asymptotic length and density. This clearly indicates density-dependent effects on growth, and we propose a model that can be used to predict the size-at-age of Norwegian spring-spawning herring as a function of herring density (the abundance of two successive cohorts) in short-term predictions of catch advice, and in Management strategy evaluations, including estimation of their reference points such as FMSY.

Climate change increases the need to control range-extending species, which adversely impact their recipient ecosystem. Increasing populations of resident predators may be effective to counter such range-extension, but only if they consume the novel invaders at sufficient rates. In South-East Australia, poleward range-extending Longspined Sea Urchins (Centrostephanus rodgersii) are causing catastrophic ecological habitat transition to extensive urchin barrens. Tasmanian native Southern Rock Lobster (Jasus edwardsii) is a potential predator that could control further urchin expansion. Experimental feeding trials showed that range-extending Longspined Sea Urchins are the least preferred prey choice for Southern Rock Lobsters (3.8% predation events), when compared to three local species: abalone, urchins, and snails (36.6, 32.6, and 27%). Interestingly, habitat origin and naivete of lobsters to urchins affected urchin consumption with 85% being consumed by lobsters originating from urchin barrens. Low predation rates on Longspined Sea Urchin suggest that resident lobsters are unlikely to control further barren expansion unless a behavioural shift occurs. Results imply that potential control of Longspined Sea Urchins by Southern Rock Lobsters has previously been overestimated. Additional control methods are needed to safeguard ecological communities and important commercial stocks from this climate change-induced, range-extending pest species.
A Characterization of a Finite-Dimensional Commuting Square Producing a Subfactor of Finite Depth
Authors: Kawahigashi Yasuyuki
Published: March 2022

We give a characterization of a finite-dimensional commuting square of $C^*$-algebras with a normalized trace that produces a hyperfinite type II$_1$ subfactor of finite index and finite depth in terms of Morita equivalent unitary fusion categories. This type of commuting squares was studied by N. Sato and we show that a slight generalization of his construction covers the fully general case of such commuting squares. We also give a characterization of such a commuting square that produces a given hyperfinite type II$_1$ subfactor of finite index and finite depth. These results also give a characterization of certain 4-tensors that appear in recent studies of matrix product operators in 2D topological order.

Flualprazolam is a novel psychoactive substance in the benzodiazepine class that is increasing in prevalence in the USA. This study describes 19 cases of drivers stopped for impaired driving where flualprazolam was detected. This represents ∼9% of the total cases submitted to the Sedgwick County Regional Forensic Science Center toxicology laboratory between July 2019 and May 2020. Blood concentrations of flualprazolam ranged from 4 to 69 ng/mL, with mean and median concentrations of 20.9 ng/mL and 15 ng/mL, respectively. The increased prevalence in which laboratories are detecting flualprazolam along with the low concentrations necessary for pharmacological effects illustrates the importance of laboratories to remain vigilant in testing for novel psychoactive substances.
The pleiotropic roles of cGAS–STING signaling in the tumor microenvironment
Authors: Li Jun , Bakhoum Samuel F
Published: March 2022

Cytosolic DNA is prevalent in cells constituting the tumor microenvironment (TME) and can activate the cyclic guanosine monophosphate–adenosine monophosphate synthase (cGAS)–stimulator of interferon genes (STING) innate immune pathway. The initiation, transmission, and execution of the cGAS–STING pathway can take place among different cell types within the TME and thus cGAS–STING may play opposing roles in driving tumor progression in addition to its tumor cell-intrinsic role. Herein, we review recent advances in the cGAS–STING field with a focus on its crosstalk with other signaling pathways in the TME. Future efforts to depict a more detailed picture of the roles of cGAS–STING signaling in the TME will help design a better cancer treatment regime by targeting the cGAS–STING pathway more precisely.

Dengue Hemorrhagic Fever (DHF) is a major mosquito-borne viral disease. Studies have reported a strong correlation between weather, the abundance of Aedes aegypti, the vector of DHF virus, and dengue incidence. However, this conclusion has been based on the general climate pattern of wide regions. In general, however, the human population, level of infrastructure, and land-use change in rural and urban areas often produce localized climate patterns that may influence the interaction between climate, vector abundance, and dengue incidence. Thoroughly understanding this correlation will allow the development of a customized and precise local early warning system. To achieve this purpose, we conducted a cohort study, during January-December 2017, in 16 districts in Bandung, West Java, Indonesia. In the selected areas, local weather stations and modified light mosquito traps were set up to obtain data regarding daily weather and the abundance of adult female Ae. aegypti. A generalized linear model was applied to analyze the effect of local weather and female adult Ae. aegypti on the number of dengue cases. The result showed a significant non-linear correlation among mosquito abundance, maximum temperature, and dengue cases. Using our model, the data showed that the addition of a single adult Ae. aegypti mosquito increased the risk of dengue infection by 1.8%, while increasing the maximum temperature by one degree decreased the risk by 17%. This finding suggests specific actionable insights needed to supplement existing mosquito eradication programs.
Patronage and ideology: A corpus-assisted investigation of Eileen Chang’s style of translating herself and the other
Authors: Chen Fengde , Li Defeng
Published: March 2022

Eileen Chang, a Chinese literary giant, was also a translator who translated both herself and other novelists. This study investigates Chang’s translator style by examining her Chinese translations of two successful English novels, The Rice-Sprout Song written by herself and The Yearling by Marjorie Kinnan Rawlings, adopting a corpus-assisted approach, supplemented with some qualitative analysis. Significant differences were found in Chang’s translations of these two novels. Chang’s self-translation was found to be close to her style of creative Chinese writing, though not without exception. It was further found that emotional particles and a Chinese conjunction ‘yinwei’ served as Chang’s approach to render her mannerism. The hallmarks of Chang’s translations could be traced to her own views on literature and translation alongside the ideological and socio-cultural motivations in her times.

Magnetic interactions between stars and close-in planets may lead to a detectable signal on the stellar disc. HD 189733 is one of the key exosystems thought to harbour magnetic interactions, which may have been detected in 2013 August. We present a set of 12 wind models at that period, covering the possible coronal states and coronal topologies of HD 189733 at that time. We assess the power available for the magnetic interaction and predict its temporal modulation. By comparing the predicted signal with the observed signal, we find that some models could be compatible with an interpretation based on star–planet magnetic interactions. We also find that the observed signal can be explained only with a stretch-and-break interaction mechanism, while that the Alfvén wings scenario cannot deliver enough power. We finally demonstrate that the past observational cadence of HD 189733 leads to a detection rate of only between 12 and 23 per cent, which could explain why star–planet interactions have been hard to detect in past campaigns. We conclude that the firm confirmation of their detection will require dedicated spectroscopic observations covering densely the orbital and rotation period, combined with scarcer spectropolarimetric observations to assess the concomitant large-scale magnetic topology of the star.
An extended and fragmented Alfvén zone in the Young Solar Wind

Published: March 2022

Motivated by theoretical, numerical, and observational evidence, we explore the possibility that the critical transition between sub-Alfvénic flow and super-Alfvénic flow in the solar atmosphere takes place in fragmented and disconnected subvolumes within a general Alfvén critical zone. The initial observations of sub-Alfvénic periods by Parker Solar Probe near 16 R⊙ do not yet provide sufficient evidence to distinguish this possibility from that of a folded surface that separates simply connected regions. Subsequent orbits may well enable such a distinction, but here we use a global magnetohydrodynamic model of the solar wind, coupled to a turbulence transport model, to generate possible realizations of such an Alfvén critical zone. Understanding this transition will inform theories of coronal heating, solar wind origin, solar angular momentum loss, and related physical processes in stellar winds beyond the Sun.

Background

The Undetectable = Untransmittable (U = U) campaign advances the goal of ending the HIV epidemic by promoting durable viral suppression and therefore reducing sexual transmission. We used geospatial analysis to assess the potential for sexual HIV transmission by ZIP code of residence in the District of Columbia (DC) using data from the DC Cohort Longitudinal HIV Study (DC Cohort), a city-wide cohort of persons with HIV (PWH).

Methods

DC Cohort participants aged ≥13 years were included in the study period between April 1, 2016, and March 31, 2018. Potential for sexual HIV transmission was defined as the proportion of participants with incident sexually transmitted infection (STI; gonorrhea, chlamydia, syphilis) and with HIV RNA ≥200 copies/mL from 9 months before to 3 months after STI diagnosis. We performed geographic information system (GIS) analysis to determine the ZIP codes with the highest potential for sexual HIV transmission.

Results

Of 3467 participants, 367 (10.6%) had at least 1 incident STI, with 89.4% residing in 11 of the 20 residential ZIP codes in DC. Of the 367 participants with an incident STI, at least 1 HIV RNA was available for 348 (94.8%). Ninety-seven (27.9%) individuals with an incident STI had HIV RNA ≥200 copies/mL in the defined time window. Of these 97, 66 (68.0%) resided in 5 of the 20 DC ZIP codes.

Conclusions

In DC, 5 ZIP codes of residence accounted for the majority of the estimated potential for HIV transmission among participants in the DC Cohort. These results support focused neighborhood-level interventions to help end the HIV epidemic.

Published: March 2022

There is growing evidence that patients with severe systemic illness from coronavirus disease 2019 (COVID-19) are at risk for developing a variety of cardiac arrhythmias. Less is known about patients with milder symptoms. Here, we report on the case of a 62-year-old male, admitted to the hospital following an episode of syncope, who experienced multiple episodes of cardiac arrest due to asystole lasting up to 30 seconds. History revealed a recent asymptomatic COVID-19 infection, and recurrent episodes of prolonged asystole necessitated permanent pacemaker placement. To our knowledge, this is the first report of an asymptomatic COVID-19 patient experiencing prolonged asystole. Cardiac arrhythmias in asymptomatic or oligosymptomatic COVID-19 patients may be underestimated.

Published: March 2022

Periodic paralysis is a rare muscle disease that manifests as episodes of painless muscle weakness, and the hypokalemic form is commonly associated with hyperthyroidism. Most tachyarrhythmias related with thyrotoxicosis include sinus tachycardia and atrial fibrillation, but an association between thyrotoxic hypokalemic periodic paralysis and typical atrial flutter has seldomly been documented. Here, we present the case of a young male who was diagnosed with thyrotoxic periodic paralysis causing cavotricuspid isthmus-dependent atrial flutter, successfully treated with diltiazem, propranolol, methimazole, potassium iodine (SSK) and rivaroxaban.
Health reforms and policy capacity: the Canadian experience
Authors: Denis Jean-Louis , Usher Susan , Préval Johanne
Published: March 2022

Recent work on health system strengthening suggests that a combination of leadership and policy capacity is essential to achieve transformation and improvement. Policy capacity and leadership are mutually constitutive but difficult to assemble in a coherent and consistent way. Our paper relies on the nested model of policy capacity to empirically explore how health reformers in seven Canadian provinces address the question of policy capacity. More specifically, we look at emerging representations of policy capacity within the context of health reforms between 1990 and 2020. Based on the exploration of the scientific and grey literature (legislation, annual reports of Ministries, agencies and organizations, meeting minutes, press, etc.) and interviews with key informants (n = 54), we identify how policy capacity is considered and framed within health reforms A series of core dilemmas emerge from attempts by each province to develop policy capacity for and through health reforms.
