Best of Both Worlds Guarantees for Smoothed Online Quadratic Optimization

We study the smoothed online quadratic optimization (SOQO) problem where, at each round $t$, a player plays an action $x_t$ in response to a quadratic hitting cost and an additional squared $\ell_2$-norm cost for switching actions. This problem class has strong connections to a wide range of application domains including smart grid management, adaptive control, and data center management, where switching-efficient algorithms are highly sought after. We study the SOQO problem in both adversarial and stochastic settings, and in this process, perform the first stochastic analysis of this class of problems. We provide the online optimal algorithm when the minimizers of the hitting cost function evolve as a general stochastic process, which, for the case of martingale process, takes the form of a distribution-agnostic dynamic interpolation algorithm (LAI). Next, we present the stochastic-adversarial trade-off by proving an $\Omega(T)$ expected regret for the adversarial optimal algorithm in the literature (ROBD) with respect to LAI and, a sub-optimal competitive ratio for LAI in the adversarial setting. Finally, we present a best-of-both-worlds algorithm that obtains a robust adversarial performance while simultaneously achieving a near-optimal stochastic performance.
Site Index Curve for Taiwania Plantations in the Liukuei Area

An effective characterization of site quality is very important in forest management. Dominant height growth is calculated as a function of tree age and site, and, therefore, the evaluation of site quality is a prerequisite to computing the stand dominant height growth. Both anamorphic curves and polymorphic curves approaches were used to develop the site index model for Taiwania plantations in the Liukuei area, and their accuracy and precision were compared. Pairs of heightage observations were obtained through a stem analysis. The results indicated that based on simultaneously considering the accuracy and precision, i.e., the mean square error (MSE), the base-agespecific site index model developed by Payandeh and Wang (1994) and modified by this study was the best at estimating the site index value for all tree ages observed. In relative terms, the mean bias was ＜3% for the chosen model in the validation dataset. While there is an advantage that the estimate and application of the base-age-invariant site index model was not affected by the baseage used, this study showed a great large loss of accuracy and precision caused by base-age-invariant models, especially for those trees younger than 11 yr. Moreover, the accuracy of the site index model varied considerably depending on the choice predictor age in estimating the site index value at the base age. This study showed the tendency that for a predictor age, the closer to the base age it was, the higher the accuracy that was obtained.
Circulating endothelial progenitor cells from septic patients are associated with different infectious organisms.

BACKGROUND In sepsis, endothelial progenitor cells (EPCs) play a central role in the repair of endothelial injury by enhancing the processes of re-endothelialization and angiogenesis. However, the surface markers of EPCs have yet to be standardized, and Changes of EPCs in quantities and functions with different infectious organisms are still unclear. This study explored the relationship between the percentages of EPCs and various infectious organisms in patients with sepsis. METHODS Thirty-nine septic patients and 20 healthy controls were enrolled in this study. The percentages of CD34+/KDR+, CD133+/KDR+, CD34+/CD133+/KDR+, CD34+, CD133+, and KDR+ cells in different groups of septic patients and the healthy controls were analyzed by flow cytometry. RESULTS The peripheral blood of septic patients had higher percentages of EPCs than that of the healthy controls. There were no significant differences in the percentages of EPCs between the sepsis and septic shock groups, nor between the survival group and the non-survival group. Additionally, the percentages of CD34+/CD133+/KDR+ cells in the gram-positive bacteremia group were significantly higher than those in the gram-negative bacteremia group and the negative blood culture group. The percentage of KDR+ cells in both the gram-positive bacteremia group and the gram-negative bacteremia group was significantly higher than that in the negative blood culture group. CONCLUSIONS The percentages of circulating EPCs in patients with sepsis are associated with different infectious organisms.

Fish diversity and community structure in a tributary stream of the Paraná River Diversidade e estrutura da comunidade de peixes em um arroio tributário do Rio Paraná

Aim: The purpose of this study was to analyze the spatial and temporal variation in the structure of the fish assemblage of the Garupa Stream, one of the tributaries of the Parana River, by considering composition, abundance and diversity. Methods: Eight samplings were carried out from April 2003 to December 2004 in the upper, middle and lower stretches of the stream, with six gill nets with mesh sizes ranging from 3 to 12 cm (between opposite knots). Results: Fifty seven species, grouped in 5 orders, 16 families and 41 genera, were identified. The Garupa stream presents a longitudinal zonation, the lower stretch presented a high diversity (4.73 bits) as compared to the middle (2 bits) and upper stretches (2.9 bits), and too the highest capture per unit of effort (4,234 g 24 h/130 m 2 ), Astyanax cf. fasciatus was the most abundant species in the upper and middle stretches and Hypostomus luteomaculatus, Schizodon nasutus and Hypostomus commersoni were the most abundant species in the lower stretch. By means of cluster analysis of species diversity of sites and season sampling, the upper and middle stretches were clustered together. The lower stretch, on the other hand, presented seasonal variations in diversity. Conclusions: the great predominance of Characiformes over Siluriformes was evident in the upper stretch of the Garupa stream, whereas it was not so evident in the mouth. This difference may be related to the different environments of the stream. Species richness in this study can be considered high. The greatest diversity was recorded in the potamon. Autumn and winter being the seasons of highest diversity, these variations could be associated with the use of the environment by the fishes of the Parana river.
Placenta Accreta Spectrum in Unscarred Uterus: A Case Report in a Tertiary Facility

Background: Placenta accreta spectrum (PAS) is a broad term that includes placenta accreta, placenta increta, and placenta percreta. The major risk factor is a scarred uterus commonly as a result of prior cesarean delivery, myomectomy, or uterine instrumentation. We report a case of placenta increta in the absence of identifiable risk factors. Case presentation: A 22-year-old, para 2 living 2, presented with postpartum hemorrhage due to retained placenta post vaginal delivery at a gestational age of 38 weeks and 4 days, manual removal of placenta was attempted general anesthesia without success; necessitating explorative laparotomy where the placenta was found deeply invading into the myometrium. Intractable bleeding necessitated supracervical hysterectomy. Histopathological results later revealed placenta increta. Conclusion: PAS in an unscarred uterus in the absence of other identifiable risk factors is quite uncommon; however, carries high maternal morbidity and mortality. This case serves as an eye opener on the need to evaluate for radiological features of PAS during antenatal visits even in low-risk group.
Terms of use : Click here Characters and growth of admissible representations of reductive p-adic groups

We use coefficient systems on the affine Bruhat–Tits building to study admissible representations of reductive p-adic groups in characteristic not equal to p. We show that the character function is locally constant and provide explicit neighbourhoods of constancy. We estimate the growth of the subspaces of invariants for compact open subgroups.
The effectiveness and cost-effectiveness of the Incredible Years® Teacher Classroom Management programme in primary school children: results of the STARS cluster randomised controlled trial

Background. We evaluated the effectiveness and cost-effectiveness of the Incredible Years® Teacher Classroom Management (TCM) programme as a universal intervention, given schools ’ important influence on child mental health. Methods. A two-arm, pragmatic, parallel group, superiority, cluster randomised controlled trial recruited three cohorts of schools (clusters) between 2012 and 2014, randomising them to TCM (intervention) or Teaching As Usual (TAU-control). TCM was delivered to teachers in six whole-day sessions, spread over 6 months. Schools and teachers were not masked to allocation. The primary outcome was teacher-reported Strengths and Difficulties Questionnaire (SDQ) Total Difficulties score. Random effects linear regression and marginal logistic regression models using Generalised Estimating Equations were used to analyse the outcomes. Trial registration: ISRCTN84130388. Results. Eighty schools (2075 children) were enrolled; 40 (1037 children) to TCM and 40 (1038 children) to TAU. Outcome data were collected at 9, 18, and 30-months for 96, 89, and 85% of children, respectively. The intervention reduced the SDQ-Total Difficulties score at 9 months (mean ( S . D .):5.5 (5.4) in TCM v. 6.2 (6.2) in TAU; adjusted mean difference = − 1.0; 95% CI − 1.9 to − 0.1; p = 0.03) but this did not persist at 18 or 30 months. Cost-effect-iveness analysis suggested that TCM may be cost-effective compared with TAU at 30-months, but this result was associated with uncertainty so no firm conclusions can be drawn. A priori subgroup analyses suggested TCM is more effective for children with poor mental health. Conclusions. TCM provided a small, short-term improvement to children ’ s mental health particularly for children who are already struggling. the study children during the study follow-up. Schools access to other training and support services not restricted.
East Antarctic Ice Sheet fluctuations during the Middle Miocene Climatic Transition inferred from faunal and biogeochemical data on planktonic foraminifera (ODP Hole 747A, Kerguelen Plateau)

This research focuses on a detailed study of faunal and biogeochemical changes that occurred at ODP Hole 747A in the Kerguelen Plateau region of the Southern Ocean during the middle Miocene (14.8-11.8 Ma). Abundance fluctuations of several planktonic foraminiferal taxa, stable oxygen isotope and Mg/Ca ratios have been integrated as a multi-proxy approach to reach a better understanding of the growth modality and fluctuations of the East Antarctic Ice Sheet (EAIS) during this period. A 7°C decrease in Sea Surface Temperature (SST), an abrupt turnover in the planktonic foraminiferal assemblage, a 1.5‰ shift towards heavier δO values (Mi3 event) and a related shift towards heavier seawater δO values between 13.9 and 13.7 Ma, are interpreted to reflect rapid surface water cooling and EAIS expansion. Hole 747A data suggest a major change in the variability of the climate system fostered by EAIS expansion between 13.9 and 13.7 Ma. Ice sheet fluctuations were greater during the interval 14.8-13.9 Ma compared with those from 13.7 to 11.8 Ma, whereas the latter interval was characterized by a more stable EAIS. In our opinion, the middle Miocene ice sheet expansion in Antarctica represents a first step towards the development of the modern permanent ice sheet. Citation: Verducci, M. , L. M. Foresi, G. H.

EPPO Datasheet: Drosophila suzukii

In June 1916, maggots were found to be infesting cherries (Prunus avium) in Yamacho, Higashi Yamanashi County, Yamanashi Prefecture, Japan (Kanzawa, 1935). Infested fruits were collected and the adult flies that emerged were confirmed as a species of Drosophila (Kanzawa, 1935). The species was later described in 1931 by Dr Shounen Matsumura as Drosophila suzukii Matsumura, and he gave it the common name of cherry drosophila (Kanzawa, 1935). Little is known about its geographical origin; it is considered native to Far-East Asia (China, Japan and Korean Peninsula) but it was described also in the Kashmir region of India as the D. suzukii subspecies indicus (Parshad and Paika, 1965). D. suzukii belongs to the subgenus Sophophora, which is divided into several species groups. One of them, the melanogaster species group, also contains the famous species, extensively used in experimental biology and genetics, Drosophila melanogaster Meigen (Powell, 1997). The melanogaster group is further divided into species subgroups, one of which (the suzukii subgroup) comprises, together with 6 other subgroups, the ‘Oriental lineage’ (Kopp and True, 2002; Schawaroch, 2002; van der Linde et al., 2010). However, relationships between and within these subgroups are still far from being resolved, and the suzukii subgroup itself is commonly regarded as polyphyletic (Kopp and True, 2002). Recent papers suggested that D. biarmipes is a sister taxon of D. suzukii (Yang et al., 2011; Chiu et al., 2013; Ometto et al., 2013; Rota Stabelli et al., 2013), in accordance with previous findings (Kopp and True, 2002; Barmina and Kopp, 2007). However, other studies by Prud’homme et al. (2006) and van der Linde and Houle (2008) supported that D. subpulchrella is a sister species of D. suzukii (with D. biarmipes being the sister species of D. subpulchrella + D. suzukii).

Seasonal and system wise variation in disease and insect pest incidence in plantation crops of Wayanad district

A study was undertaken in the plantation crop based cropping system plots of Wayanad district to assess disease and pest incidence during different seasons in major crops and the variations in incidence of disease and pests between various cropping systems. In coconut, grey blight was extremely high during all seasons. Eriophyid mite attack was highest during south west (SW) monsoon (80%). Arecanut palms were mainly infected by Colletotrichum leaf spot, grey blight, inflorescence blight& button shedding and leaf rot during all seasons. Spindle bug infestation was highest during north east (NE) monsoon season (46.6%). In pepper, foot rot, yellow mottle, fungal pollu and marginal thrips was noticed in all seasons. In coffee, severe incidence of Colletotrichum leaf spot was noticed during summer (65.1%). Cardamom plants were mainly affected by leaf rot, leaf blotch and shoot borer during all the three seasons. In tea, the incidence of grey blight and stem borer attack was highest during summer. Study of seasonal variation in disease/ insect pest incidence between cropping systems showed that in arecanut, spindle bug attack was relatively greater when intercropped with nutmeg and tea during summer, with banana and nutmeg during SW monsoon and with coconut during NE monsoon. Incidence of foot rot was more in pepper grown along with tea during all seasons. During the two monsoon seasons, blister blight of tea was more in tea with pepper as intercrop and sooty mould was higher in tea intercropped with arecanut.
A Revised Radiocarbon Chronology of the Aceramic Shell Midden of Ra’s Al-Hamra 6 (Muscat, Sultanate of Oman): Implication For Occupational Sequence, Marine Reservoir Age, and Human Mobility

Abstract Ra’s al-Hamra 6 (RH-6) is one of the earliest stratified archaeological sites along the eastern littoral of the Arabian Peninsula. This shell midden was radiocarbon dated to the 6th–5th millennium cal BC, but the majority of the dates were obtained before the advent of accelerator mass spectrometry (AMS) 14C dating and suffer from large uncertainties. In addition, most of these dates were obtained on marine and mangrove shells and required correction for local variations from the global average marine 14C reservoir age (MRA). This proved difficult because no consensus value exists for this period in the area. Recent excavations at RH-6 offered the opportunity to redate this important site in order to precisely determine its occupation history and later use as a graveyard, and establish the marine reservoir effect for this time period. Thirty-eight samples of charcoal, shells, and human bone apatite were selected for 14C dating. Bayesian modeling of the 14C dates suggests that the formation of the shell midden spanned ~1 millennium, between the mid-6th and the mid-5th millennium cal BC. Positive and consistent ΔR values were calculated throughout the entire sequence, ranging from 99±27 to 207±43 14C yr. At the beginning of the 4th millennium cal BC, RH-6 was used as a graveyard, as suggested by the 14C dating of a shell in strict association with an individual buried at the surface of the site. 14C dating of human bone apatite allowed us to calculate that 89% of this individual’s diet derived from marine resources. This finding confirms previous observations showing the overwhelming presence of marine and mangrove-dwelling species in the faunal and charcoal assemblage, and implies a low mobility, or mobility restricted to the coast for this population during the 4th millennium cal BC.
