Next-to-Next-to-Leading Order Study of Three-Jet Production at the LHC.

Multijet rates at hadron colliders provide a unique possibility for probing quantum chromodynamics (QCD), the theory of strong interactions. By comparing theory predictions with collider data, one can directly test perturbative QCD, extract fundamental parameters like the strong coupling α_{s}, and search for physics beyond the standard model. In this work we calculate, for the first time, the next-to-next-to-leading order (NNLO) QCD corrections to typical three-jet observables and to differential three-to-two jet ratios.

Higher Order Corrections to Spin Correlations in Top Quark Pair Production at the LHC.

We calculate, for the first time, the next-to-next-to-leading order (NNLO) QCD corrections to spin correlations in top quark pair production at the LHC. The NNLO corrections play an important role in the description of the corresponding differential distributions. We observe that the standard model calculation describes the available Δϕ_{ℓℓ} data in the fiducial region but does not agree with the Δϕ_{ℓℓ} measurement extrapolated to full phase space.

Diabetes Care in Republic of Macedonia: Challenges and Opportunities.

Background: The Republic of Macedonia (RoM) has experienced a rapid rise in the prevalence of type 2 diabetes (T2D) over the past 2 decades, a period characterized by significant social, political, and economic change. RoM now has one of the highest rates of diabetes in Europe.

Objectives: To explore the modifiable conditions that may underlie and exacerbate the T2D epidemic; describe the state of diabetes care; and consider improved mechanisms for prevention and treatment, including research priorities, in RoM.

High-Precision Differential Predictions for Top-Quark Pairs at the LHC.

We present the first complete next-to-next-to-leading order (NNLO) QCD predictions for differential distributions in the top-quark pair production process at the LHC. Our results are derived from a fully differential partonic Monte Carlo calculation with stable top quarks which involves no approximations beyond the fixed-order truncation of the perturbation series. The NNLO corrections improve the agreement between existing LHC measurements [V.

Resolving the Tevatron Top Quark Forward-Backward Asymmetry Puzzle: Fully Differential Next-to-Next-to-Leading-Order Calculation.

We determine the dominant missing standard model (SM) contribution to the top quark pair forward-backward asymmetry at the Tevatron. Contrary to past expectations, we find a large, around 27%, shift relative to the well-known value of the inclusive asymmetry in next-to-leading order QCD. Combining all known standard model corrections, we find that A(FB)(SM)=0.

Removing gaps in the exclusion of top squark parameter space.

Light stops are a hallmark of the most natural realizations of weak-scale supersymmetry. While stops have been extensively searched for, there remain open gaps around and below the top mass, due to similarities of stop and top signals with current statistics. We propose a new fast-track avenue to improve light stop searches for R-parity-conserving supersymmetry by comparing top cross section measurements to the theoretical prediction.

Total top-quark pair-production cross section at hadron colliders through O(αS(4)).

We compute the next-to-next-to-leading order (NNLO) quantum chromodynamics (QCD) correction to the total cross section for the reaction gg → tt + X. Together with the partonic channels we computed previously, the result derived in this Letter completes the set of NNLO QCD corrections to the total top pair-production cross section at hadron colliders. Supplementing the fixed order results with soft-gluon resummation with next-to-next-to-leading logarithmic accuracy, we estimate that the theoretical uncertainty of this observable due to unknown higher order corrections is about 3% at the LHC and 2.

Percent-level-precision physics at the Tevatron: next-to-next-to-leading order QCD corrections to qq¯→tt¯+X.

We compute the next-to-next-to-leading order QCD corrections to the partonic reaction that dominates top-pair production at the Tevatron. This is the first ever next-to-next-to-leading order calculation of an observable with more than two colored partons and/or massive fermions at hadron colliders. Augmenting our fixed order calculation with soft-gluon resummation through next-to-next-to-leading logarithmic accuracy, we observe that the predicted total inclusive cross section exhibits a very small perturbative uncertainty, estimated at ±2.

Estimate of B(B(over) -->Xgamma) at O(alpha(s)2).

Combining our results for various O(alpha[s]) corrections to the weak radiative B-meson decay, we are able to present the first estimate of the branching ratio at the next-to-next-to-leading order in QCD. We find B(B[over ]-->X[s]gamma)=(3.15+/-0.

[The views and attitudes of the Clinic of Emergency Surgery of the Clinical Emergency Medical Center at the Queen Ioanna State University Hospital on the potentials of surgical endoscopy in upper digestive hemorrhages].

Transendoscopic sclerotherapy of esophageal varix in children and adults is introduced in the clinic of emergency surgery ever since 1973. In children aged 3 to 14 years presenting preportal block a 100 per cent survivorship is recorded 20 years after the manipulation. The outcome of endoscopy in adult patients is successful in 57.

[Anaerobic surgical infection and septic shock].

In the period 1990 through 1995, one-hundred patients operated for acute abdomen or admitted on a routine basis, presenting evidence of anaerobic infection, undergo treatment in the clinic of emergency surgery. Septic shock develops in 10/100 patients (10 per cent). In six of the latter the outcome is fatal--three with infection caused by spore-forming anaerobes (gas gangrene of the inguinal region--of Fournier, and anterior abdominal wall--anus praeternaturalis--two), and three with infection caused by non-spore-forming anaerobes (mixed anaerobic-aerobic infection).

[Transendoscopic drug denervation of the stomach in emergency surgical diseases of the gastrointestinal tract (a preliminary report)].

This is the first, preliminary report on the implementation of transendoscopic medicamentous denervation of the stomach as a therapeutic approach to acute surgical diseases of the gastrointestinal tract. Diminishing the vagus nerve influence after the method described contributes to a substantial improvement of the treatment results in acute pancreatitis patients by shortening the term of therapeutic fasting, avoiding nasogastric tube insertion, and making unnecessary H2-blockers application. TEMDS is indicated in all instances of acute pancreatitis, bleeding duodenal ulcer, bleeding ulcus pepticum jejuni following BII resection of the stomach.

[The current aspects of the diagnosis and procedure in gastroduodenal hemorrhages of ulcerous origin].

Basic problem in all discussions on bleeding gastroduodenal ulcers is the one pertaining to the surgical tactics and to the ascertainment of the indications for surgical intervention and the time for its performance. Adequate answer to this question comes from recognition of the following points: 1. Endoscopically established bleeding source and intensity; 2.

[The diagnostic and treatment problems in closed diaphragmatic trauma].

Twenty four patients with blunt trauma of the diaphragm comprise the study group. Four of them died of accompanying injuries in other anatomical regions. All patients had the left leaf of the diaphragm affected.

[The results and a discussion of the esophagogastroduodenoscopic studies performed successfully, early and postponed in patients with upper digestive tract hemorrhages in 1980-1990].

For a period of 10 years (1980-1990) a total of 2034 emergency, early and postponed endoscopies have been performed in patients with upper digestive tract bleeding at the Department of Emergency Surgery in Sofia. Duodenal ulcer has been the leading cause of bleeding--41.19 per cent of the cases, with gastric ulcer ranking second--14.

[Our experience with diathermy coagulation as a form of therapeutic endoscopy in acute upper digestive tract hemorrhages].

In addition to sclerosifying by use of fibroendoscope which acts upon the source of bleeding, to achieve hemostasis and prevent bleeding relapses nowadays other methods have also gained acceptance. Major importance among these is attached to diathermocoagulation. It may principally be assumed that diathermocoagulation is indicated for critically ill patients with serious accompanying diseases of primary or secondary importance, as well as in the event of persistent bleeding during the clinical examination and impending resumption of bleeding soon after the examination.

[Therapeutic esophagoscopy based on a portal and preportal block in hemorrhaging varices of the esophagus and portal hypertension].

Parallel with the hitherto known methods of treatment of bleeding esophageal varicosities in portal hypertension with Seinkstaken-Blackmore's probe and by surgical approaches for controlling the hemorrhage from ruptured esophageal varicosities, such as Cryle's and Linton's operations, azigoportal deconnection by Tanner's technique, splenectomy, omentohepatoplexy, Sugiura's operation, esophagus ligation by the method of Fosschulte and V. Mateev (1983), the authors apply the method of transendoscopic sclerosification of bleeding varicosities in adults and children with cirrhosis of the liver and prehepatic block. The indications and contraindications of the method and the etiologic factors underlying portal and preportal block in adults and children (in adults--cirrhosis of the liver, in children--mostly preportal block secondary to portal vein thrombosis dating back to early childhood after exchange transfusion through the umbilical vein) are discussed.

[Hemorrhage from acute erosive processes in the upper digestive tract in thermal trauma].

Forty-six patients with thermic trauma complicated by bleeding from the gastroduodenal tract have been observed during the period 1975-1985. The nosologic entities with bleeding symptom were as follows: hemorrhagic gastritis--2 patients, acute ulcer--5, inveterate callous ulcer--5. Transendoscopic operation (electrocoagulation + sclerosification) was performed in 5 patients with acute ulcers, and conventional surgery--in patients.

[The immediate results of transendoscopic sclerotherapy in hemorrhaging varices, tumors and polyps and in the Mallory-Weiss syndrome].

In 1982 four Japanese authors Okaba, Honda, Toshiba and Asami reported at the International Symposium in Tokyo on successful transendoscopic sclerosification of bleeding ulcer, around which a sclerosifying agent or absolute alcohol was injected with or without epinephrine. Alcohol suppresses bleeding, causing local dehydration, coagulation and sclerosis of the bleeding tissue, thus producing hemostasis. For the last two years the authors have gained some experience in the application of periulcer and peritumor sclerosification with the sclerosifying agent etoxysclerol (3 per cent solution) and pure 96 per cent ethanol + 1 ampoule epinephrine.

[Hemorrhage from the digestive tract in the Mallory-Weiss syndrome].

Thirty-three patients with Mallory-Weiss syndrome have been treated at the Clinic of Emergency Surgery in Sofia for a period of 11 years (1980-1990). According to treatment and outcome they were classified as follows: conservative treatment--7 patients, electrocoagulation--16, sclerosing procedure--10, successful endoscopic hemostasis--17, emergency surgical intervention--9, relapse of bleeding after endoscopic surgery--9, death from hemorrhage--4, total case fatality--12.1 per cent, operative case fatality rate--33.

[Changes in the water-electrolyte and protein balance of the body in acute gastrointestinal ulcerative hemorrhage].

The authors studied 127 patients, divided into 4 groups, relating to the haemorrhage stage in accordance with the classification of Lutsevich. It has been established that there exist changes in the hydroelectrolytic and protein balance of the patients having acute gastrointestinal ulcerative haemorrhage.

[The problems of severe combined chest and heart trauma].

On the basis of the experience and the analysis of 3818 cases of combined chest traumas the injuries in different anatomical areas have been observed. A special place was given for the diagnostics, the variety of the clinical conditions, the treatment and the prognosis of the reasons for lethality in cases with such traumas. With the increase of the affected anatomical areas the lethality increases proportionally too.

[Our experience in the diagnosis and treatment of traumatic pneumothorax].

The clinical material summarized is derived from the observation of 150 patients. The accent is put on the faults in the X-ray interpretation of the pneumothorax and on the mistaken tactics in the treatment of the pneumothorax, which led to four lethal cases. The attention is drawn to the importance of the prompt physical study of traumatic patients, which gives the opportunity for prompt diagnosis and urgent adequate treatment.
