The Hierarchical Learning Algorithm for Deep Neural Netwprks
Authors: Płaczek Stanisław , Płaczek Aleksander
Published: August 2018

In the article, the emphasis is put on the modern articial neural network (ANN) structure, which in the literature is known as a deep neural network. A network includes more than one hidden layer and comprises many standard modules with ReLu nonlinear activation function. A learning algorithm includes two standard steps, forward and backward, and its effectiveness depends on the way the learning error is transported back through all he layers to the first layer. Taking into account all the dimensionalities of matrixes and the nonlinear characteristics of ReLu activation function, the problem is very challenging. In practice tasks, a neural networks internal layer matrixes with ReLu activations function, include a lot of null value of weight coeffcients. This phenomenon has a negative impact on the effectiveness of the learning algorithm's convergence. Analyzing and describing an ANN structure, one usually finds that the first parameter is the number of ANNs layers "L". By implementing the hierarchical structure to the learning algorithm, an ANN structure is divided into sub-networks. Every sub-network is responsible for finding the optimal value of its weight coeffcients using a local target function to minimize the learning error. The second coordination level of the learning algorithm is responsible for coordinating the local solutions and finding the minimum of the global target function. In each iteration the coordinator has to send coordination parameters into the first level of subnetworks. By using the input and the teaching vectors, the local procedures are working and finding their weight coeffcients. At the same step the feedback error is calculated and sent to the coordinator. The process is being repeated until the minimum of all the target functions is achieved.
A study on the coexistence analysis of intelligent transport systems in 60GHz bands
Authors: Choi Suna
Published: August 2018

As information provided by intelligent transport systems is expanded from simple traffic information to high-resolution maps for autonomous driving and various infotainment services, the need for additional frequency allocation is increasing. Therefore, in Europe, the 63-64GHz band is allocated in addition to the existing 5.9GHz. However, the 60GHz band is used for unlicensed services and the wireless multi-gigabit service is already utilized in the frequency band. For the safe utilization of the frequency band, coexistence analysis between the intelligent transport systems and the wireless multi-gigabit service is required. In this paper, the coexistence between the two services in the 60GHz band is analyzed assuming the case that the same millimeter wave frequency as Europe is allocated for intelligent transport systems in various countries. First, the international specifications and characteristics of the wireless multi-gigabit service and intelligent transport systems are investigated. Furthermore, protection distances between the two services in various application scenarios are analyzed based on the minimum coupling loss. The results show that a careful consideration of frequency allocation for ITS is required for the safe coexistence. The coexistence analysis presented in this paper is expected to be used as a guideline in millimeter wave frequency allocation for ITS.

Authors: Luu Khoi , Nguyen Duc Trung , Van Luu Xuan
Published: August 2018

Each firm in the oligopoly plays off of each other in order to receive the greatest utility, expressed in the largest profits, for their firm. When analyzing the market, decision makers develop sets of strategies to respond the possible actions of competitive firms. In international stage, firms are competitive and they have different business strategies, their interaction becomes essential because the number of competitors is increased. This paper will provide an examination in international trade balance and public policy under Cournot’s framework. The model shows how the oligopolistic firm can decide the business strategy to maximize its profit given others’ choice, and how the public maker can find out the optimal tariff policy to maximize its social welfare. The discussion in this paper can be significant for both producers in deciding their quantities needed to be sold in not only domestic market but also international stage in order to maximize their profits and governments in deciding the tariff rate on imported goods to maximize their social welfare.

Authors: Bonella Belen Maria , Warley Fernando
Published: August 2018

Cyclophosphamide-associated hyponatremia is an uncommon adverse effect. Published reports are inconclusive regarding patients under high-dose therapy. Objective: To determine the incidence of hyponatremia in patients under high-dose cyclophosphamide therapy. Methods: Retrospective cohort of adult patients who received high-dose cyclophosphamide therapy between 2010 and 2014 at the Hospital Italiano de Buenos Aires. The primary end-point was hyponatremia (defined as plasma sodium levels < 135 mEq/L), and secondary end-points were symptomatic hyponatremia, severe hyponatremia (plasma sodium levels < 120 mEq/L). Results: A total of 96 patients received high-dose cyclophosphamide therapy during the study period. 27 patients met exclusion criteria and accounted for 28.1% , so that 69 patients were included in the primary analysis. Study population mean age was 56.5 years (SD 12.8) and 37.6% were female. The cumulative incidence were as follows: 52% (CI 95% 39¬–64) for hiponatremia, 5.8% (CI 95% 0–12) for severe hyponatremia, and 8.7% (CI 95% 1.3–16) for symptomatic hyponatremia. The only independent variable associated with the development of hyponatremia was female gender (OR 3.89, CI 95% 1.02–8.55, p=0.04). Cumulative incidence found in this study appears higher than in previous reports, probably because only patients under high-dose cyclophosphamide therapy were included. Cumulative incidence of severe and symptomatic hyponatremia were lower

Polyphenols provide by diet may act as antioxidant in the Central Nervous System and exert a protective effect on metabolic diseases. The aim of this study was to establish tea extract effects on oxidative status and murine overweight in accordance with polyphenolic availability in different encephalic regions. Methods: Balb/c mice (female, n>3) with overweight received for 15 days 100 mg/Kg/d of extract from Lantana grisebachii, Aspidosperma quebracho-blanco, or Ilex paraguariensis extracts and control group (received water without extract). Body weight gain was recorded regularly. Polyphenols, hydroperoxides (HP), lipid peroxides (LP), and superoxide anion (SO) were measured in brain (telencephalon and diencephalon), midbrain, brainstem and cerebellum. Results were compared by ANOVA followed by the Tukey test (P<0.05). Results: A. quebracho-blanco-based treatment decreased weight gain and increased polyphenols in brainstem (p<0.02), although it concomitantly increased SO and LP in this region (p=0.0029 and p=0.0280, respectively). L. grisebachii-based treatment reduced oxidative markers differentially in each region (p<0.05). I. paraguariensis-based treatment oxidized midbrain and cerebellum, although it was antioxidant in the brainstem (p<0.05). All treatments were antioxidant in telencephalon (p=0.0029). Conclusions: The A. quebracho-blanco extract was active on overweight and increased polyphenols in brainstem, with safe functional derivatives being required to avoid oxidative stress. Other extracts affected oxidative status in a region-dependent manner.

Introduction: an exponential law has been found for chaotic dynamic cardiac systems, making it possible to quantify the differences between normal and pathological cardiac dynamics. Methodology: 120 electrocardiographic records were analyzed, 40 corresponded to subjects within the limits of normality and 80 with different pathologies. For each holter the attractors generated with the data during 18 hours and throughout the dynamics were analyzed. The fractal dimension of the attractor and its spatial occupation were calculated. To these measures was applied the diagnosis mathematical evaluation previously developed, comparing the evaluation for 18 hours and for the whole registry; sensitivity, specificity and Kappa coefficient were finally calculated. Results: For the normal dynamics, the occupancy spaces in the Kp grid were between 200 and 381 for the evaluation of the whole holter, and between 201 and 384 in the evaluation during 18 hours, showing the closeness in the measurements, which allows that the decrease in the time of the evaluation is consistent, this same proximity was observed for the diseased and acute dynamics. Conclusion: It was evidenced the clinical applicability in 18 hours of the exponential law in the chaotic cardiac dynamics associated with arrhythmias showing to be useful for the prediction of the evolution towards acute states of the dynamics
Vigilancia de la sensibilidad a penicilina en Streptococcus agalactiae recuperados de embarazadas entre las 35-37 semanas de gestación

Published: August 2018

Streptococcus agalactiae (GBS) cause severe infections in newborns under three months. Meningitis, pneumonia and sepsis are the main infectious diseases in these children. These infections are among the most serious that an individual can suffer in his first twelve hours of life. The child acquires the infection by vertical transmission of the colonized mother. To prevent neonatal disease, penicillin is recommended as the drug of choice for intrapartum prophylaxis (PIP) in pregnant women colonized. However, strains with decreased susceptibility to penicillin have been detected so it is important to monitor the susceptibility to penicillin to ensure its usefulness during prophylaxis. The aim of this study was to determine the sensitivity to penicillin in GBS strains recovered from pregnant women with 35-37 weeks of gestation. Ninety-six isolates were studied and sensitivity was determined by the epsilometric method Etest® (LIOFILCHEM, Italy), following the recommendations of the Clinical Laboratory Standards Institute (CLSI). Minimum Inhibitory Concentration (MIC) was obtained for each bacterial isolation. 100% (96) of the strains studied were sensitive to penicillin with MIC values between 0.012 and 0.094 ?g mL-1. These results indicate that penicillin remains the antimicrobial of choice during intrapartum prophylaxis, for the prevention of neonatal disease caused by GBS in our region. The importance of epidemiological surveillance of sensitivity to penicillin and other antimicrobials is highlighted in order to alert new resistance mechanisms and to adapt treatment strategies.

The patient is monitored and a venous peripheral access is placed. It is remarkable the variable blood pressure measures in the semi-stationary position, both in the upper left limb as in the contralateral limb. In the upper left limb we registrered 220/80 mmHg, followed by 100/50 mmHg and finally 170/95 mmHg. In the upper right limb, blood pressure was 180/40 mmHg and afterwards 120/70 mmHg. Proximal and distal pulses are present and no pulsatile epigastric mass can be found. Given the suspicion of an aortic syndrome, a CT scan with intravenous contrast is performed which shows a large hiatal hernia compromising partially the left atrium and inferior lobar veins (Fig 1-4). The patient is transferred to the observation area, where a nasogastric tube is placed, presenting partial symptomatic improvement, with persistent nausea and vomiting, as well as a tendency to hypertension. After being evaluated by general surgery, it was decided to make an hernia content reduction to the abdominal cavity and posterior fundoplication with residual fundus (Toupet type). There were no perioperative complications. After several days of hospitalization, the patient was referred to his home with no further incidences.

When push comes to shove in recreational ﬁshing compliance, think ‘nudge’
Authors: Mackay Mary , Jennings Sarah , van Putten E.I. , Sibly Hugh , Yamazaki Satoshi
Published: August 2018

Enforcing compliance with rules and regulations in recreational fisheries has proved difficult due to factors such as the high number of participants and costs of enforcement, the absence of regular monitoring of recreational fishing activity, and the inherent difficulties in accurately determining catch levels. The effectiveness of traditional punitive deterrence is limited, yet current management is heavily reliant on this compliance approach. In this paper, the potential of behavioural based management is considered through a narrative review of the relevant literature; specifically, exploring the use of nudges, which aim through subtle changes and indirect suggestion to make certain decisions more salient, thereby improving voluntary compliance. This concept is explored with specific reference to the compliance of fishers within Australian recreational fisheries. There are only a few examples of behavioural based approaches found. However, based on their theoretical foundations, nudges may represent an inexpensive, and potentially highly effective tool for recreational fisheries management. Nudges do not offer a ‘quick fix’ to cases where traditional policy instruments have failed. Rather, there is the potential for behavioural nudges (based on framing, changing the physical environment, presenting default options, and social norms) to augment and complement existing deterrence regimes. A number of potential nudges for compliance management in recreational fisheries are suggested, but caution is advised. As with any novel management approach, nudges must be rigorously tested to demonstrate their cost-effectiveness and to avoid unintended consequences.
Increases in Sex with Same-Sex Partners Across U.S. Cohorts Born 1920-1998: A Race-Gender Intersection
Authors: Mishel Emma , England Paula , Ford Jessie , Caudillo Monica
Published: August 2018

We examine change across U.S. cohorts born between 1920 and 1998 in their probability of having had sex with same-sex partners last year and since age 18. We explore how trends differ by gender, race and class background. We use data from the 1988-2016 General Social Surveys. We find steady increases across birth cohorts in the proportion of men and women who have had both male and female sexual partners since age 18. A key finding is a race-gender intersection: black men and women of all races had similar increases— increases which were much steeper than those observed for white men. We suggest that women’s increase is rooted in a long-term asymmetry in gender change, in which nonconformity to gender norms in many arenas is more acceptable for women than men. As the increase for men is largest among black men—and this is the population most affected by the rise of mass incarceration—we suggest the latter may be a contributing factor.

The software package HSC-5.1, based on the principle of Gibbs energy minimum uses in the study. The influence of temperature (from 500 to 2500 °C) and the amount of carbon (from 40 to 60 % of the basalt mass) in the basalt–Fe–nC system was determined. It has been established that iron silicides are formed at T ≥ 1300 °C, Si at T ≥ 1400 °C, CaSi and Al at T> 1700 °C and CaC2 – at T ≥ 1800 °C. An increase of the amount of carbon from 40 to 60 % allows rise the degree of distribution of Si in the alloy up to 94 %, calcium in CaCl2 – up to 62.3 %, aluminum – to alloy up to 93.9 %. An increase of the amount of carbon allows increase the silicon concentration in alloy up to 55 % (at 1800 °C), aluminum – up to 17 % (at 2000 °C) and calcium carbide capacity – up to 350 dm3/kg. The method of rototable planning of the second order allows find equations of regressions of the influence of temperature and amount of carbon on the equilibrium distribution of silicon, aluminum, and calcium between the ferroalloy and calcium carbide. On the basis of this equations were determined, that within the temperature range 1956-1996 °C from the Dubersay deposit basalt, the ferroalloy with a content of ΣSi and Al 60.8-65.4 % (including 12- 15 % Si) and calcium carbide with a capacity of 250-300 dm3/kg are formed. Wherein degree of recovery into the alloy for silicon is 91-91.4 % and for aluminum is 63-75.1 % and calcium – into CaC2 is 60-60.7 %. The resulting ferroalloy by the content of silicon and aluminum can be attributed to the complex ferroalloy – ferrosilicoaluminium, calcium carbide – to the industrial product of grade from 3 and up to the highest.

OBJECTIVE

The authors studied the clinical characteristics and postoperative outcomes of drug-resistant epilepsy associated with focal gliosis.

METHODS

From their epilepsy surgery database, the authors selected the patients with drug-resistant epilepsy and MRI-defined focal gliosis who underwent focal resective surgery. All patients underwent standard presurgical evaluation. Intracranial electroencephalography (EEG) was performed in patients with discordant presurgical data, ill-defined lesions, and lesions close to eloquent regions. Completeness of resection was defined on the basis of extraoperative and intraoperative electrocorticography studies. Favorable postoperative outcome was defined as Engel class I outcome during the last 2 years of follow-up.

RESULTS

Sixty-six patients fulfilled inclusion criteria. An initial precipitating injury was present in 38 (57.6%) patients, mainly in the form of perinatal injury (n = 10), trauma (n = 10), and meningoencephalitis (n = 8). Gliosis involved a single lobe in 38 (57.6%) patients and 2 adjacent lobes in 14 (21.2%) patients; the remaining 14 (21.2%) patients had multilobar gliosis. In patients with unilobar or bilobar gliosis, the posterior region of the head was involved in 34 (65%) patients and the frontal lobes in 12 (23%) patients. During a median follow-up of 4 years (range 2–9 years), 41 (62.1%) patients had favorable outcome. On multivariate analysis, the presence of a well-defined aura (p = 0.019), electrocorticographically defined completeness of resection (p = 0.024), and normal postoperative EEG findings at 1 year (p = 0.003) were predictive of favorable postoperative seizure outcome.

CONCLUSIONS

Focal gliosis is a common etiology for drug-resistant extratemporal epilepsy in developing countries and is most often located in the posterior region of the head. The majority of these patients have perinatal injuries or neurological infections as initial precipitating injuries. Patients with focal gliosis have good postoperative seizure outcomes after well-planned resective surgery.

OBJECTIVE

Adhesion formation is one of the most common complications following laminectomy. The efficiency of antiadhesive agents is required to prevent postsurgical adhesion. Therefore, the authors investigated the effects of silk solution against laminectomy-induced dural adhesion formation in a rat model.

METHODS

The authors prepared the silk solution from silkworms. Laminectomies were performed between L3 and L5 in all rats. MediShield was used as a control. The effects of silk solution against laminectomy-induced dural adhesion formation and inflammation were confirmed by histological examination and Western blot analysis.

RESULTS

Laminectomy-induced dural adhesion formation was drastically reduced in silk solution–treated rats (Grade 2) compared to vehicle-treated rats (Grade 3). Dural adhesion formation was significantly reduced in rats that received treatment with silk solution or MediShield, which is a known antiadhesion drug. In addition, combined treatment with silk solution and MediShield showed greater reductions in inflammation compared to the silk solution– or MediShield-treated rats (p > 0.05).

CONCLUSIONS

In this study, the authors demonstrated that silk solution effectively reduced postlaminectomy dural adhesion formation in rats. Although further studies on the long-term effects are necessary to validate these results, silk solution may potentially serve as an antiadhesion agent in neurological procedures.
Tailored suprainsular partial hemispherotomy: a new functional disconnection technique for stroke-induced refractory epilepsy

OBJECTIVE

Hemispherotomy is currently the most frequently performed surgical option for refractory epilepsy associated with large perinatal or childhood ischemic events. Such an approach may lead to good seizure control, but it has inherent functional consequences linked to the disconnection of functional cortices. The authors report on 6 consecutive patients who presented with severe epilepsy associated with hemiplegia due to stroke and who benefitted from a new, stereoelectroencephalography-guided partial disconnection technique.

METHODS

The authors developed a new disconnection technique termed “tailored suprainsular partial hemispherotomy” (TSIPH). Disconnection always included premotor and motor cortex with variable anterior and posterior extent.

RESULTS

At a mean follow-up of 28 months, there were no deaths and no patient had hydrocephalus. Motor degradation was observed in all patients in the 2 weeks after surgery, but all patients completely recovered. The 6 patients were seizure free (Engel class IA) at the last follow-up. No neuropsychological aggravation was observed.

CONCLUSIONS

TSIPH appears to be a conservative alternative to classic hemispherotomy, leading to favorable outcome in this series.

OBJECTIVE

Topical antimicrobial compounds are safe and can reduce cost and complications associated with surgical site infections (SSIs). Topical vancomycin has been an effective tool for reducing SSIs following routine neurosurgical procedures in the spine and following adult craniotomies. However, widespread adoption within the pediatric neurosurgical community has not yet occurred, and there are no studies to report on the safety and efficacy of this intervention. The authors present the first institution-wide study of topical vancomycin following open craniotomy in the pediatric population.

METHODS

In this retrospective study the authors reviewed all open craniotomies performed over a period from 05/2014 to 12/2016 for topical vancomycin use, SSIs, and clinical variables associated with SSI. Topical vancomycin was utilized as an infection prophylaxis and was applied as a liquid solution following replacement of a bone flap or after dural closure when no bone flap was reapplied.

RESULTS

Overall, 466 consecutive open craniotomies were completed between 05/2014 and 12/2016, of which 43% utilized topical vancomycin. There was a 1.5% SSI rate in the nontopical cohort versus 0% in the topical vancomycin cohort (p = 0.045). The number needed to treat was 66. There were no significant differences in risk factors for SSI between cohorts. There were no complications associated with topical vancomycin use.

CONCLUSIONS

Routine topical vancomycin administration during closure of open craniotomies can be a safe and effective tool for reducing SSIs in the pediatric neurosurgical population.

O presente trabalho tem como objetivo investigar o potencial da narrativa enquanto instrumento de intervenção psicológica em um CAPSI, a partir da apresentação de um estudo de caso individual. As elaborações teórico-reflexivas fundamentam-se na Teoria das Representações Sociais (DUVEEN; LLOYD, 2008), em diálogo com a Teoria Histórico-Cultural (AGUIAR; OZELLA, 2006; MOLON, 1999; PRESTES, 2010; VIGOTSKI, 2009; 2010a; 2010b). Além dos estudos sobre narrativas (BRUNER, 1997; 2001; 2002; JOVCHELOVITCH; BAUER, 2002). Os dados discutidos foram engendrados nas análises das intervenções realizadas em oficinas socioafetivas (ANDRADE, 2015), tematizadas diante da apresentação de uma narrativa, através da qual propôs-se a construção de uma narrativa coletiva a um grupo de adolescentes. As múltiplas faces da narrativa criada por uma adolescente foram identificadas no primeiro momento do processo, quando esteve em pauta a idealização do estado de bem-estar, saúde e felicidade, em contraposição à caracterização de sua condição de usuária, cujas narrativas são registradas em prontuário – narrativas defensivas. No segundo momento, observou-se a emergência de narrativas espontâneas, quando ela assume seu papel de protagonista na produção do enredo coletivo, liberta-se das preocupações relativas ao protocolo de tratamento e anuncia conteúdos e conflitos juntamente com metáforas que deixam ver seu processo de enfrentamento do desconhecido.
A PESQUISA BIOGRÁFICA OU A CONSTRUÇÃO COMPARTILHADA DE UM SABER DO SINGULAR
Authors: Delory-Momberger Christone
Published: August 2018

O artigo buscará revisitar os fundamentos epistemológicos e metodológicos da pesquisa biográfica em Educação a partir de duas questões: Qual o saber que a pesquisa biográfica busca ? Como a pesquisa biográfica constrói este saber? A primeira questão permitirá reafirmar a especificidade e a centralidade do fato biográfico nos processos de individuação e de socialização e interrogar o campo de conhecimento aberto à pesquisa biográfica, descrevendo operações e noções centrais  (atividade biográfica, biografização, biograficidade). A segunda questão levará à exploração dos modos de construção de um saber do biográfico que não pode ser, de uma parte, senão que um saber do singular  encontrando sua fonte em particular nas narrações individuais, e que não pode se construir, de outra parte, senão na base de uma pesquisa colaborativa na qual estão engajados pesquisadores e pessoas sobre/com as quais eles “pesquisam”. Os elementos de resposta trazidos para este duplo questionamento serão enfim mobilizados para tentar esclarecer a compreensão e uso dos termos pesquisa biográfica/pesquisa biográfica em educação para designar nossa corrente de pesquisa.
