ANALYSING THE IMPACT OF PENALTY CONSTANT ON PENALTY FUNCTION THROUGH PARTICE SWARM OPTIMIZATION
Authors: Prajapati Raju , Dubey Om Prakash 
Published: July 2018

Non Linear Programming Problems (NLPP) are tedious to solve as compared to Linear Programming Problem (LPP). The present paper is an attempt to analyze the impact of penalty constant over the penalty function, which is used to solve the NLPP with inequality constraint(s). The improved version of famous meta heuristic Particle Swarm Optimization (PSO) is used for this purpose. The scilab programming language is used for computational purpose. The impact of penalty constant is studied by considering five test problems. Different values of penalty constant are taken to prepare the unconstraint NLPP from the given constraint NLPP with inequality constraint. These different unconstraint NLPP is then solved by improved PSO, and the superior one is noted. It has been shown that, In all the five cases, the superior one is due to the higher penalty constant. The computational results for performance are shown in the respective sections.
Rozwój małych miast powiatowych województwa wielkopolskiego w ujęciu koncepcji urban resilience
Authors: Konecka-Szydłowska Barbara 
Published: July 2018

Nowa koncepcja badawcza miast urban resilience (prężności miejskiej) pozwala na podstawie analizy trajektorii rozwoju miast określić poziom prężności i wrażli­wości gospodarki miast na zachodzące zakłócenia. Celem niniejszej pracy jest przedstawienie trajektorii rozwoju małych miast powiatowych województwa wielkopolskiego w ujęciu kon­cepcji urban resilience. Badanie prężności i wrażliwości ośrodków powiatowych w wymiarze ekonomicznym prowadzi się przy wykorzystaniu wartości indeksów dynamiki zmian o stałej podstawie. W analizie uwzględniono zróżnicowaną strukturę gospodarczą miast. Zakres czaso­wy opracowania obejmuje lata 2005–2015. Uzyskane wyniki pozwalają stwierdzić, że ośrodki powiatowe o usługowej i bardziej zdywersyfikowanej strukturze gospodarki charakteryzują się większą odpornością na zakłócenia zewnętrzne i wyższym poziomem prężności w wymiarze ekonomicznym. Miasta o strukturze mieszanej i mniejszej dywersyfikacji gospodarki posia­dają relatywnie bardziej zamkniętą gospodarkę, na którą nie oddziałują w znaczącym stopniu zakłócenia zewnętrzne i wykazują niższy poziom prężności.

Lumbar Intervertebral Disc Herniation Masquerading as an Epidural Hematoma
Authors: Jain Nikhil , Crouser Nisha , Yu Elizabeth 
Published: July 2018

Case:
A 50-year-old man developed acute back and bilateral leg pain after minor trauma. Laboratory tests and routine radiographs were unremarkable. Magnetic resonance imaging (MRI) showed a 5 × 15 × 42-mm longitudinally oriented mass behind the L2-L3 interspace that obliterated the subarachnoid space and displaced the nerve roots. The mass was isointense on T1-weighted imaging and showed mixed low and high signals on T2-weighted imaging. Based on the clinical history and the imaging findings, a provisional diagnosis of spinal epidural hematoma (SEH) was made. A laminectomy was performed at L2-L3; intraoperatively, a large disc herniation was found at L2-L3, with no evidence of hematoma.

Conclusion:
MRI findings of SEH and disc herniation have been well described in the literature. To our knowledge, this is the third report of intraoperatively confirmed disc herniation with MRI findings suggestive of SEH These discordant MRI and intraoperative findings illustrate that an SEH and a disc herniation may not always be distinguishable on MRI and may require surgical confirmation.
Bilateral Macrodactyly of the Halluces in an Adolescent Girl Corrected with Shortening Osteotomies of the First Metatarsal and the Phalangeal Bones
Authors: Kalb Juan Pedro , Suarez David Andrés , Herrera Ana Milena 
Published: July 2018

Case:
A 14-year-old girl presented with painful high-arched feet and unusual, asymptomatic, bilateral macrodactyly of the halluces. After a year of observation, a surgical reduction was performed because of the psychological effect that the abnormality had on the patient. Bilateral shortening osteotomies of the metatarsal and the proximal phalangeal bones were performed. At 2 months after surgery, complete bone healing and alignment had been achieved. At the 5-year follow-up, we noted fully functional big toes, plantigrade feet, bilateral proper toe formula, and extreme patient satisfaction with the cosmetic results.

Conclusion:
Dual osteotomies for toe shortening in a patient with bilateral nondysmorphic macrodactyly provided appropriate length reduction and satisfactory aesthetic and functional results.
The Practice of Overlapping Surgery Is Safe in Total Knee and Hip Arthroplasty
Authors: Suarez Juan C. , Al-Mansoori Ahmed A. , Borroto Wilfredo J. , Villa Jesus M. , Patel Preetesh D. 
Published: July 2018

Background:
Overlapping surgery occurs when a surgeon performs 2 procedures in an overlapping time frame. This practice is commonplace in the setting of total joint arthroplasty and is intended to increase patient access to experienced surgeons, improve efficiency, and advance the surgical competence of surgeons and trainees. The practice of overlapping surgery has been questioned because of safety and ethical concerns. As the literature is scarce on this issue, we evaluated the unplanned hospital readmission and reoperation rates associated with overlapping and non-overlapping total joint arthroplasty procedures.

Methods:
We reviewed 3,290 consecutive primary total knee and hip arthroplasty procedures that had been performed between November 2010 and July 2016 by 2 fellowship-trained senior surgeons at a single institution. Overlapping surgery was defined as the practice in which the attending surgeon performed a separate procedure in another room with an overlapping room time of at least 30 minutes. Patient baseline characteristics and 90-day rates of complications, readmissions, and reoperations were compared between overlapping and non-overlapping procedures. Subanalyses also were done on patients with a body mass index (BMI) of ≥30 kg/m2 and those with an American Society of Anesthesiologists (ASA) score of 3 or 4. The level of significance was set at 0.05.

Results:
Of the 2,833 procedures that met the inclusion criteria, 57% (1,610) were overlapping and 43% (1,223) were non-overlapping. Baseline demographics, BMI, and ASA scores were similar between the groups. No significant differences were found between the overlapping and non-overlapping procedures in terms of the 90-day rates of complications (5.2% vs. 6.6%, respectively; p = 0.104), unplanned readmissions (3.4% vs. 4.3%; p = 0.235), or reoperations (3.1 vs. 3.1; p = 1.0) in the analysis of the entire cohort or in subgroup analyses of obese patients and patients with an ASA score of 3 or 4. The total mean operating room time was 5.8 minutes higher for overlapping procedures.

Conclusions:
Overlapping procedures showed no increase in terms of the 90-day rates of complications, readmissions, or reoperations when compared with non-overlapping procedures. There was just over a 5-minute increase in mean operating room time for overlapping procedures. Our data suggest that overlapping surgery does not lead to detrimental outcomes following total knee arthroplasty or total hip arthroplasty. Future investigations evaluating patient-oriented outcomes and satisfaction are warranted.

Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Background and objectivesHDL particles obtained from patients on chronic hemodialysis exhibit lower cholesterol efflux capacity and are enriched in inflammatory proteins compared with those in healthy individuals. Observed alterations in HDL proteins could be due to effects of CKD, but also may be influenced by the hemodialysis procedure, which stimulates proinflammatory and prothrombotic pathways.Design, setting, participants, & measurementsWe compared HDL-associated proteins in 143 participants who initiated hemodialysis within the previous year with those of 110 participants with advanced CKD from the Hemodialysis Fistula Maturation Study. We quantified concentrations of 38 HDL-associated proteins relative to total HDL protein using targeted mass spectrometry assays that included a stable isotope–labeled internal standard. We used linear regression to compare the relative abundances of HDL-associated proteins after adjustment and required a false discovery rateqvalue ≤10% to control for multiple testing. We further assessed the association between hemodialysis initiation and cholesterol efflux capacity in a subset of 80 participants.ResultsAfter adjustment for demographics, comorbidities, and other clinical characteristics, eight HDL-associated proteins met the prespecified false discovery threshold for association. Recent hemodialysis initiation was associated with higher HDL-associated concentrations of serum amyloid A1, A2, and A4; hemoglobin-β; haptoglobin-related protein; cholesterylester transfer protein; phospholipid transfer protein; and apo E. The trend for participants recently initiating hemodialysis for lower cholesterol efflux capacity compared with individuals with advanced CKD did not reach statistical significance.ConclusionsCompared with advanced CKD, hemodialysis initiation within the previous year is associated with higher concentrations of eight HDL proteins related to inflammation and lipid metabolism. Identified associations differ from those recently observed for nondialysis-requiring CKD. Hemodialysis initiation may further impair cholesterol efflux capacity. Further work is needed to clarify the clinical significance of the identified proteins with respect to cardiovascular risk.PodcastThis article contains a podcast at https://www.asn-online.org/media/podcast/CJASN/2018_07_25_CJASNPodcast_18_8_W.mp3
Mecanosíntesis y efecto antimicrobiano de óxidos metálicos nanoestructurados
Authors: Vázquez Olmos América Rosalba , Vega Jiménez Alejandro Luis , Paz Díaz Blanca 
Published: July 2018

Actualmente existe un gran interés en Centro de Ciencias Aplicadas y Desarrollo Tecnológico (CCADET) de la UNAM, por el desarrollo de métodos innovadores que permitan obtener materiales nanoestructurados y en particular aquellos formados por óxidos metálicos, con actividad antimicrobiana. En este artículo se presenta lo que el grupo de investigación de la Dra. América Vázquez ha llevado a cabo sobre la mecanosíntesis de una serie de óxidos nanoestructurados formados por CuO, CuBi<sub>2</sub>O<sub>4, </sub>ZnO, Mn<sub>3</sub>O<sub>4</sub>, Fe<sub>2</sub>O<sub>3</sub>, CuFe<sub>2</sub>O<sub>4</sub>, ZnFe<sub>2</sub>O<sub>4</sub> y MgO, así como una revisión sobre las aplicaciones de dichos óxidos, como agentes antimicrobianos. <br /> La principal motivación de esta investigación radica en el hecho de que el desarrollo de nuevos antibióticos, a pesar de ser constante, resulta inútil cuando los microorganismos se vuelven multirresistentes. Por tal razón, se han buscado nuevas formas de combatir dichas infecciones y en este sentido, las nanopartículas (NPs) formadas por óxidos metálicos han resultado ser una nueva herramienta en la lucha contra las enfermedades causadas por microorganismos que cada vez se vuelven más resistentes a los tratamientos convencionales con diversos antibióticos.

The Economics of Managerial Taxes and Corporate Risk-Taking
Authors: Armstrong Christopher S. , Glaeser Stephen , Huang Sterling , Taylor Daniel J. 
Published: July 2018

ABSTRACT
We examine the relation between managers' personal income tax rates and their corporate investment decisions. Using plausibly exogenous variation in federal and state tax rates, we find a positive relation between managers' personal tax rates and their corporate risk-taking. Moreover—and consistent with our theoretical predictions—we find that this relation is stronger among firms with investment opportunities that have a relatively high rate of return per unit of risk, and stronger among CEOs who have a relatively low marginal disutility of risk. Importantly, our results are unique to senior managers' tax rates––we do not find similar relations for middle-income tax rates. Collectively, our findings provide evidence that managers' personal income taxes influence their corporate risk-taking decisions.

Tax Uncertainty and Incremental Tax Avoidance
Authors: Guenther David A. , Wilson Ryan J. , Wu Kaishu 
Published: July 2018

ABSTRACT
We investigate whether tax avoidance becomes more uncertain as the rate of tax avoidance increases. We estimate a system of equations to demonstrate that as firms' pretax income increases, each additional dollar of potential tax results, on average, in 32.8 cents of tax avoided, which we refer to as incremental tax avoidance. Of the incremental tax avoided, 1.4 cents represent additions to the reserve for uncertain tax benefits (UTB reserve), or 4.3 percent of the total incremental tax avoided. We then partition sample firms into groups that prior research suggests engage in higher rates of tax avoidance, and examine the amount of incremental tax avoidance that results in additions to the UTB reserve. Results demonstrate that the percentage of incremental tax avoidance reflecting additions to UTB reserve is not larger for groups engaging in higher rates of tax avoidance, suggesting higher rates of tax avoidance may not be more uncertain.

A NEW METHOD OF TREATMENT FOR APPENDICEAL STUMP
Authors: Charyshkin A. L. , Yartsev M. M. 
Published: July 2018

Background.In 30% of acute destructive appendicitis, the disease is accompanied by typhlitis, which makes it difficult to perform classical methods of appendiceal stump treatment.Aim of study.To improve the way of appendiceal stump treatment in the destructive form of acute appendicitis complicated by significant typhlitis.Material and methods.We studied 57 cases of acute destructive appendicitis complicated by typhlitis, which were divided into two groups depending on the method of treatment. The first group (comparison group) consisted of 30 patients who underwent a standard method for treating the appendiceal stump after appendectomy, such as ligation at the base and putting the stump into the cupula of the cecum and fixing it with interrupted serous-muscular sutures or with a purse and Z-shaped sutures. The second (main) group included 27 patients, who were treated by the method we proposed. The essence of the method is successive U-shaped stitching of the stump. After that, the stump curls in the form of a cochlea, peritonizes, reaching the necessary tightness without going into the cupula of the cecum. In this case, the abdominal cavity of patients in both groups was adequately sanitized and drained.Results.In the first group of patients there were technical difficulties associated with immersion of the appendiceal stump, which caused the serous damage, hematoma of the cupula of the cecum in 7 (23.3%) patients. In the second group of patients, due to the developed method of forming the appendiceal stump, technical difficulties did not arise, there were no complications. The duration of appendectomy in the first group of patients with standart treatment (interrupted serous-muscular sutures or purse and Z-shaped stiches) was 28.7±5.4 minutes, and in the second group of patients appendectomy with stump management with the suggested method lasted 20.3±6.1 minutes, p <0.05, which reduced the operation time by 8 minutes on the average. Purulent-inflammatory wound complications in the first group were detected in 7 patients (23.3%), and in 1 (3.7%) patient of the second group, which is significantly less by 19.6%.Conclusion.The proposed method is technically simple, as peritonization of the stump is performed without putting it into the cupula of the cecum. The use of this method is indicated in destructive forms of acute appendicitis complicated by severe typhlitis, which significantly reduces the operation trauma and contributes to reduction in the number of postoperative wound purulent-inflammatory complications by 19.6%. Findings The proposed method for treating the appendiceal stump during appendectomy for acute destructive appendicitis complicated by typhlitis is simple enough, reliable, characterized by low traumatism and shortens the duration of surgery by 8 minutes on the average (p <0.05).
