There are two approaches to merging temporal and epistemic models. The first one consists in starting with a temporal model and enriching it with epistemic dimension (as temporal epistemic logic), while the second one is supposed to start with an epistemic model introducing temporal dimension (dynamic epistemic logic, ... |
This paper presents a throughput efficient cascaded FFT architecture suitable for OFDM telecommunication applications. The design exploits a technique parallelizing the radix-2 butterfly computations to increase the throughput by 2, while it keeps the complexity of the VLSI area equal to the single path delay feedback ... |
The computational background for analysing the passive, subthreshold properties of fine-scale ramifications such as "en-passant" and "terminal ladder" type chains of boutons and spiny dendrites is presented.

-quartic mappings is introduced. The structure of such mappings is studied, and in fact, it is shown that every multiquartic mapping can be described as an equation, namely, the (generalized) multiquartic functional equation. Moreover, by applying two fixed point techniques, some results corresponding to known stabili... |
Ethiopia is a federal country wherein all regional states making the federation are required to establish an independent regional environmental agency or designate an existing agency to carry out environmental protection and management duties. In line with this, the Ethiopian Somali Regional state (one among of the fed... |
SCENES OF TRIAL abound in Renaissance drama, and they have almost received the critical attention they deserve. Not so the curious phenomenon of the ‘false trial’. Dramatic plots presented as trials often call into question the ostensible certainty of the knowledge arrived at through legal means. In Shakespeare’s All’s... |
The strong and volatile rebound of capital inflows, mostly portfolio investments, into emerging economies in the recovery process of the 2008 global financial crisis has brought the issue of capital controls to the forefront once again. The presence of global imbalances and unconventional monetary easing in advanced co... |
For the validation of aerodynamic models, certain flight trajectories have to be chosen. In the current paper, the methodology of optimum experimental design is employed for the solution of this task. Aerodynamic models are highly nonlinear and so far no optimum experimental design approaches have been applied to them.... |
As the size of solder interconnects used in electronics packaging decreases, methods for characterizing the creep behavior of solder at ever smaller length scales need to be developed. Long duration micropillar compression experiments at constant loads and temperatures ranging from 60 to 160 °C were used to characteriz... |
This article concerns recent approaches in North American historical archaeology to studying issues of ethnicity. It begins with a consideration of fundamental concepts and definitions. Next, discussions regarding the nature of archaeological research on ethnicity are offered. Consideration is given to ethnic groups, e... |
The aim of this short communication is to present an extremely uncommon case of penile metastases from rectal adenocarcinoma treated with an external beam radiotherapy technique. A 76-year-old man affected by very painful priapism from penile metastases was treated with radiotherapy (30 Gy) for symptom relief. In the c... |
Stand-alone PV schemes have found a fairly wide application in remote isolated regions to meet small but essential electric load. The capacities of such stations are commonly specified in terms of the peak power available during maximum solar insolation. The actual insolation available at a site is, however, affected b... |
In his metafictional novel Never Any End to Paris, Enrique Vila-Matas invites an audience to help him understand Hemingway’s story “Cat in the Rain” so as to write his own story, “What They Said about the Cat.” The audience’s responses recapitulate the story’s critical history, which Vila-Matas augments by observing th... |
Metabonomic screening of human urine samples using 1H NMR spectroscopy has revealed the presence of signals resulting from the excretion of ethyl glucoside. Experiments in volunteers have demonstrated that this ethyl glucoside results from dietary exposure to the compound, which is present in beverages such as rice win... |
OBJECTIVE |
The purpose of this article is to retrospectively evaluate radiologically totally implanted central venous access ports (VAPs) of the upper arm in terms of safety, technical feasibility, and device-related complications. |
MATERIALS AND METHODS |
Five hundred seven consecutive patients (mean [± SD] age, 59.2 ± 11.4 years) who received a totally implanted central VAP between January 2005 and July 2010 were included. The insertion procedure was performed in an interventional radiology suite using the Seldinger technique. Neither antibiotic prophylaxis nor long-te... |
RESULTS |
In 507 patients, a total of 523 devices were implanted. Of these 523 procedures, 512 complete datasets were available during follow-up. The primary technical success rate was 99.04%. All procedures were completed without major complications. During follow-up and with a total number of 127,750 days of totally implanted ... |
CONCLUSION |
Radiologic placement of a totally implanted central VAP is a safe procedure with a low rate of both early and late device-related complications. The method is effective for delivery of chemotherapy, parenteral nutrition, and frequent IV medication.Electrooptical Light-Management Material: Low-Refractive-Index Adhesives |
ABSTRACT A prototype pressure-sensitive adhesive that has a low refractive index (<1.36) and is optically clear has been developed (Holguin and Chang, US Patent 6703463, 2002). The refractive index is a key feature in the application of optical polymers, and this pressure-sensitive adhesive is particularly useful for l... |

To present two case reports describing the treatment of immature teeth with necrotic pulps using concentrated platelet-rich plasma (cPRP) with 12-month clinical and radiographic follow-up. |
SUMMARY |
Root canal revascularization was performed on immature permanent teeth clinically and radiographically diagnosed as requiring root canal treatment. Following disinfection of the canal space with triple antibiotic paste (1 : 1 : 1: ciprofloxacin, metronidazole and cefaclor), a tissue scaffold was created with cPRP prepa... |
Audio segmentation is an essential problem in many audio signal processing tasks, which tries to segment an audio signal into homogeneous chunks. Rather than separately finding change points and computing similarities between segments, we focus on joint segmentation and clustering, using the framework of hidden Markov ... |
PII, an ancient and widespread signaling protein, transduces nitrogen/carbon/energy abundance signals through interactions with target proteins. We clarify structurally how PII regulates gene expression mediated by the transcription factor NtcA, the global nitrogen regulator of cyanobacteria, shedding light on NtcA str... |
Childhood cancer survivors at highest risk of developing a secondary malignancy are those with hereditary retinoblastoma. The majority of such secondary cancers will be sarcomas, most commonly of bone. One-third of these occur outside a typical radiation field, commonly in an extremity.
