Perceptions of natural disturbance in Tatra National Park, Poland
Authors: Švajda Juraj , Koróny Samuel , Zięba Antoni , Adamski Paweł 
Published: October 2016

Abstract
Since the last decades, natural disturbances in forests including protected areas have intensified. They have the potential to impact visual quality and safety of visitors as well as spread beyond protected area boundaries. While economic and ecological impacts are well studied, there is still a lack of work focused on human dimensions and social aspects. This study examines visitor perceptions towards bark beetle infestation in Tatra National Park, Poland. The findings, based on visitor surveys collected during the summer of 2014, indicate the significance of different factors influencing visitor attitudes towards the bark beetle. Age of visitors and importance of the bark beetle issue for them (based on subjective ratings of importance of bark beetle issue for respondents) are the most prominent variables. Also place of origin and environmental worldview were recognized as significantly important variables in accordance with similar studies. Results suggest management implications for park authorities including public relations and environmental education in order to increase knowledge and support for natural disturbance and ecological integrity policies in the national park.
On the profinite topology on solvable groups
Authors: Alibabaei Khadijeh 
Published: October 2016

Abstract
We show that the wreath product of a finitely generated abelian group with a polycyclic group is a LERF group. This theorem yields as a corollary
that finitely generated free metabelian groups are LERF, a result due to Coulbois.
We also show that a free solvable group of class 3 and rank at least 2 does not contain a strictly ascending HNN-extension of a finitely generated group. Since such groups are known not to be LERF, this settles, in the negative, a question of J. O. Button.
Order Quantity Distributions: Estimating an Adequate Aggregation Horizon
Authors: Eriksen Poul Svante , Nielsen Peter 
Published: October 2016

Abstract
In this paper an investigation into the demand, faced by a company in the form of customer orders, is performed both from an explorative numerical and analytical perspective. The aim of the research is to establish the behavior of customer orders in first-come-first-serve (FCFS) systems and the impact of order quantity variation on the planning environment. A discussion of assumptions regarding demand from various planning and control perspectives underlines that most planning methods are based on the assumption that demand in the form of customer orders are independently identically distributed and stem from symmetrical distributions. To investigate and illustrate the need to aggregate demand to live up to these assumptions, a simple methodological framework to investigate the validity of the assumptions and for analyzing the behavior of orders is developed. The paper also presents an analytical approach to identify the aggregation horizon needed to achieve a stable demand. Furthermore, a case study application of the presented framework is presented and concluded on.
Requirements as Operational Metrics? – Case: Finnish Defense Forces
Authors: Häyhtiö Markus 
Published: October 2016

Abstract
The purpose of this paper is to study how requirements management could be utilized in connection to a service performance measurement system. Public private partnership (PPP) in Finnish Defence Forces’ (FDF) catering operations is studied as a case example.
There are two research questions, which are studied: Firstly, do catering operations create KPI’s, which enable inter-functional co-operation and service development? Secondly, do these KPIs support both efficiency and effectiveness of PPP catering operations?
Evidence from the previous studies on the subject indicates that there should be a single “power-by-the-hour” metrics unit, which enables a transparent follow-up of the performance-based operations. This research highlights requirements value in creation of economic efficiency and effectiveness from the end-user point-of view and reciprocal value creation between inter-functional service systems. This research’s results show that focus on portion control can produce information, which enhances inter-functional co-operation between PPP stakeholders.

Published: October 2016

AbstractIn this article, under the investigation on the interactions among multiple solitons for an eighth-order nonlinear Schrödinger equation in an optical fibre, oscillations in the interaction zones are observed theoretically. With different coefficients of the operators in this equation, we find that (1) the oscillations in the solitonic interaction zones have different forms with different spectral parameters of this equation; (2) the oscillations in the interactions among the multiple solitons are affected by the choice of spectral parameters, the dispersive effects and nonlinearity of the eighth-order operator; (3) the second-, fifth-, sixth-, and seventh-order operators restrain oscillations in the solitonic interaction zones and the higher-order operators have stronger attenuated effects than the lower ones, while the third- and fourth-order operators stimulate and extend the scope of oscillations.
Bagan Warna Daun: Alat untuk Meningkatkan Efisiensi Pemupukan Nitrogen pada Tanaman Padi
Authors: Erythrina Erythrina 
Published: October 2016

Nitrogen (N) merupakan unsur hara utama pada tanaman padi, tetapi ketersediaannya terbatas pada hampir semua jenis tanah. Pemberian pupuk N secara berlebihan menyebabkan tanaman berwarna hijau gelap, mudah rebah, serta rentan terhadap hama dan penyakit. Di pihak lain, kekurangan N menyebabkan tanaman tumbuh kerdil, sistem perakaran tidak berkembang, daun menjadi kuning, dan gabah cenderung cepat rontok. Makalah ini mengulas perkembangan penggunaan bagan warna daun (BWD) pada tanaman padi sawah, mencakup cara dan manfaat penggunaannya dalam meningkatkan hasil gabah, menekan serangan hama dan penyakit tanaman, serta memperbaiki kondisi lingkungan. Pemberian pupuk N sesuai kebutuhan merupakan kunci dalam memperbaiki pertumbuhan tanaman untuk memperoleh hasil yang optimal. Waktu penggunaan BWD dapat dengan dua cara, yaitu: 1) berdasarkan kebutuhan tanaman, yaitu dengan membandingkan warna daun padi dengan skala warna pada BWD dan 2) berdasarkan waktu yang telah ditetapkan, yaitu pada saat pembentukan anakan aktif (21-28 HST) dan primordia (35-40 HST). Pemberian N yang berlebihan pada stadia awal pertumbuhan tanaman meningkatkan kerentanan terhadap hama wereng coklat dan penggerek batang serta penyakit blas, sehingga rekomendasi pupuk spesifik lokasi menjadi sangat penting. Gerakan penggunaan BWD secara masif ke depan dapat didukung melalui penggunaan kamera digital atau telepon seluler beresolusi tinggi.<div style="left: 85px; top: 661.6px; font-size: 13.4px; font-family: serif; transform: scaleX(1.0996);" data-canvas-width="377.6936350612496"> </div>

Published: October 2016

In this paper, we propose a novel FPGA-based high-speed DDoS countermeasure system that can flexibly adapt to DDoS attacks while still maintaining system performance. The system includes a packet decoder module and multiple DDoS countermeasure mechanisms. We apply dynamic partial reconfiguration technique in this system so that the countermeasure mechanisms can be flexibly changed or updated on-the-fly. The proposed system architecture separates DDoS protection modules (which implement DDoS countermeasure techniques) from the packet decoder module. By using this approach, one DDoS protection module can be reconfigured without interfering with other modules. The proposed system is implemented on a NetFPGA 10G board. The synthesis results show that the system can work at up to 116.782 MHz while utilizing up to 39.9% Registers and 49.85% BlockRAM of the Xilinx Virtex xcv5tx240t FPGA device on the NetFPGA 10G board. The system achieves the detection rate of 100% with the false negative rate at 0% and false positive rate closed to 0.16%. The prototype system achieves packet decoding throughput at 9.869 Gbps in half-duplex mode and 19.738 Gbps in full-duplex mode.

Changes in FGFR2 amino-acid residue Asn549 lead to Crouzon and Pfeiffer syndrome with hydrocephalus
Authors: Apra Caroline , Collet Corinne , Arnaud Eric , Rocco Federico Di 
Published: October 2016

AbstractMutations in Fibroblast Growth Factor Receptor II (FGFR2) have been identified in patients with Crouzon and Pfeiffer syndrome, among which rare mutations of the intracellular tyrosine kinase domain. Correlating subtle phenotypes with each rare mutation is still in progress. In Necker-Enfants Malades Hospital, we identified three patients harboring three different pathogenic variants of the same amino acid residue Asn-549 located in this domain: in addition to a very typical crouzonoid appearance, they all developed clinically relevant hydrocephalus, which is an inconstant feature of Crouzon and Pfeiffer syndrome. Overall, FGFR2 tyrosine kinase domain mutations account for 5/67 (7.4%) cases in our hospital. We describe a novel mutation, p.Asn549Ser, and new cases of p.Asn549His and p.Asn549Thr mutations, each reported once before. Our three cases of Asn-549 mutations, alongside with rare previously reported cases, show that these patients are at higher risk of hydrocephalus. Clinical and imaging follow-up, with possible early surgery, may help prevent secondary intellectual disability.

Abstract
To stimulate a productive T cell response, dendritic cells (DC) must undergo maturation characterized by heightened cell surface expression of MHC and costimulatory molecules as well as cytokine production. Conversely, the inhibition of DC maturation is a central mechanism of immune tolerance. The control of the DC maturation process relies on the integration of several cellular stimulatory or inhibitory signals. The soluble factors and their receptors controlling this central aspect of DC biology are incompletely characterized. We show that murine bone marrow–derived DC (BMDC) maturation induced by LPS, as opposed to polyinosinic:polycytidylic acid or cytosine-phosphate-guanine, is robustly inhibited by vascular endothelial growth factor (VEGF), a previously identified immunosuppressive cytokine. Using BMDC from wild type and conditional knockout mice, we show that neuropilin-1 (NRP-1), a known receptor of VEGF, is necessary to suppress LPS-dependent BMDC maturation. The absence of NRP-1 had no ostensible effects on the biology of BMDC in the absence of VEGF. However, NRP-1–deficient BMDC remained completely insensitive to the VEGF-dependent inhibition of BMDC maturation in culture. In the presence of VEGF, NRP-1 directly interacted with the LPS receptor TLR4 and suppressed downstream signaling through ERK and NF-κβ, resulting in a sharp inhibition of MHC class II and costimulatory molecules (CD40, CD86) expression as well as proinflammatory cytokine production. Consequently, we identify NRP-1 as a target to optimize DC maturation within environments that are rich in VEGF, such as tumors.
Propionibacterium acnes Susceptibility and Correlation with Hemolytic Phenotype

Published: October 2016

Background Many studies have noted an increase in the number of recognized cases of invasive infections due to Propionibacterium acnes, especially after shoulder replacement surgery. The increase in the number of recognized cases of P. acnes, a nonspore-forming, anaerobic, Gram-positive organism, appears due to both an increase in the number of shoulder operations being performed and more specimens being sent for anaerobic cultures. Nevertheless, the optimal surgical and antibiotic management of P. acnes remains controversial. Methods We tested the susceptibility of 106 P. acnes strains from sterile body sites collected at the Erie County Medical Center between 2012 and 2015, using Etest gradient antibiotic strips. Results P. acnes is very susceptible to the penicillins and the first-generation cephalosporins. We noted an association between hemolytic phenotype on Brucella Blood Agar and clindamycin resistance. Conclusions Antimicrobial susceptibility testing of P. acnes should no longer just be confined to the research laboratory but expanded and incorporated into routine microbiological evaluation of P. acnes. This would improve patient care as well as help clarify the relationship between hemolysis and clindamycin resistance.
Hungarian Refugees of 1956: From the Border to Austria, Camp Kilmer, and Elsewhere
Authors: Niessen James P. 
Published: October 2016

Camp Kilmer dominates the story of flight from Hungary in 1956-1957 for many Hungarian Americans who experienced the Revolution, and with good reason: roughly four-fifths of them came through the camp, and their subsequent integration into American life was largely successful. But it is less well known that many fifty-sixers did not share this experience: as many may have returned to Hungary as came to the US, and by far most of the refugees ended up in other countries. US restrictions on entry steered many refugees to other countries, but the US provided most of the funding for the international relief effort. This article seeks to relativize the myth of Camp Kilmer by examining the refugees’ motives for leaving Hungary, their experience in Austria, and why so many ended up in the US, in other countries, or back in their homeland.
Production of acrylic acid and propionic acid by constructing a portion of the 3-hydroxypropionate/4-hydroxybutyrate cycle from Metallosphaera sedula in Escherichia coli
Authors: Liu Zhijie , Liu Tiangang 
Published: October 2016

Abstract
Acrylic acid and propionic acid are important chemicals requiring affordable, renewable production solutions. Here, we metabolically engineered Escherichia coli with genes encoding components of the 3-hydroxypropionate/4-hydroxybutyrate cycle from Metallosphaera sedula for conversion of glucose to acrylic and propionic acids. To construct an acrylic acid-producing pathway in E. coli, heterologous expression of malonyl-CoA reductase (MCR), malonate semialdehyde reductase (MSR), 3-hydroxypropionyl-CoA synthetase (3HPCS), and 3-hydroxypropionyl-CoA dehydratase (3HPCD) from M. sedula was accompanied by overexpression of succinyl-CoA synthetase (SCS) from E. coli. The engineered strain produced 13.28 ± 0.12 mg/L of acrylic acid. To construct a propionic acid-producing pathway, the same five genes were expressed, with the addition of M. sedula acryloyl-CoA reductase (ACR). The engineered strain produced 1430 ± 30 mg/L of propionic acid. This approach can be expanded to synthesize many important organic chemicals, creating new opportunities for the production of chemicals by carbon dioxide fixation.
Our experience with adnexal masses in the pediatric age group and review of literature
Authors: Khedkar Kiran , Shah Hemanshi , Tiwari Charu , Makhija Deepa , Waghmare Mukta 
Published: October 2016

Background and objectives:
Adnexal masses are rare in the pediatric age group. We present our experience with 20 patients with adnexal masses.

Design and setting:
This retrospective observational analysis was performed on 20 children with adnexal masses who were treated at our institute between May 2011 and November 2015. Patients and methods: Fifteen pediatric patients who were admitted between May 2011 and November 2015 were reviewed and retrospectively analyzed based on their age at the time of admission, their presenting complaints, clinical and radiological findings, tumor markers, management and follow-up.

Results:
The patients’ age at the time of admission ranged between 3 days and 12 years. Abdominal pain and lump were the most common presenting complaints.
Four patients (20%) had antenatally diagnosed cystic ovarian lesions. On postnatal scan, two patients had a simple cyst measuring less than 6 cm, which resolved on follow-up ultrasound at 3 months. One neonate had a simple cyst, larger than 6 cm on postnatal scan, which was managed by marsupialization. One antenatally diagnosed patient had a dermoid cyst that required oophorectomy.
Ten patients (50%) had dermoid cyst and underwent complete surgical excision of the mass. Based on histopathologic results, two of these patients had immature teratoma and required adjuvant chemotherapy (Bleomycin, Etoposide, and Cisplatin). The serum AFP levels of these patients were carefully monitored.
One patient with bilateral ovarian cysts was diagnosed with Van Wyk—Grumbach syndrome, which resolved significantly after a 3-month regimen of thyroxin supplementation.
Five patients presented with torsion and required emergency surgery—three had mature teratoma, one had an immature teratoma and one had large simple cysts.

Conclusion:
The majority of ovarian tumors are benign. Accurate staging, complete resection and chemotherapy for the treatment of malignant tumors have contributed to excellent survival rates in these patients.

ABSTRACTIntroductionHypogonadism in men is often associated with poor libido, erectile dysfunction, irritability, fatigue, and psychological and relationship problems. Many of these symptoms can be best assessed through patient report. The 28-item Hypogonadism Impact of Symptoms Questionnaire (HIS-Q) was developed to evaluate hypogonadism symptoms in men with low testosterone in the context of clinical trials.AimTo develop a briefer version of the HIS-Q that could be practical for use in treatment settings.MethodsParticipants with low testosterone levels and symptoms consistent with hypogonadism were recruited through clinical sites. Focus groups and interviews were conducted to elicit symptom concepts and identify those that were most relevant to patients, including changes as a consequence of treatment.Main Outcome MeasuresSystematic analysis of the qualitative data and expert clinician input were used to develop the HIS-Q short form (HIS-Q-SF). One-on-one cognitive interviews were conducted to confirm the content validity of the HIS-Q-SF.ResultsThirty-five men participated in this qualitative research. Concept elicitation was conducted through focus group discussions (n = 18) and telephone interviews (n = 2); then, the draft HIS-Q-SF was evaluated through cognitive interviews (n = 15). The mean age of total sample was 53.2 ± 6.8 years, and the mean serum total testosterone level was 184.9 ± 55.2 ng/dL. Results suggest that the HIS-Q-SF has demonstrated content validity, including the content coverage, comprehensibility, and the appropriateness of the response options and recall period. The final version of the HIS-Q-SF includes 17 items and is aligned with the original longer version of the instrument.ConclusionThe HIS-Q-SF is a comprehensive measurement of hypogonadism symptom severity in men. Content coverage and content validity were confirmed. The instrument will be evaluated further to establish the psychometric characteristics and to assess the utility of the measurement in clinical treatment settings.
