Form factor in K+ --> pi+ pi0 gamma: interference versus direct emission

We analyze the effect of a form factor in the magnetic contribution to K+ --> pi+ pi0 gamma. We emphasize how this can show up experimentally: in particular we try to explore the difference between a possible interference contribution and a form factor in the magnetic part. The form factor used for K+ --> pi+ pi0 gamma is analogous to the one for KL --> pi+ pi- gamma, experimentally well established.Comment: 9 pages revtex, 10 eps figures; improved presentation of theoretical and experimental status; refs. adde

Adnexal Torsion in Pediatric Age: Does Bolli's Score Work? Report of Two Cases

Adnexal torsion is a surgical emergency requiring early diagnosis in order to avoid demolitive surgery. Adnexal torsion's diagnosis could be very difficult in pediatric patients because children cannot explain symptoms accurately. Furthermore reproductive organs lie high in abdomen, causing unclear examinations findings. For reducing diagnostic mistakes or delay clinical and hematological criteria could be useful. No radiological criteria (CT or MRI) should be taken in count because of the costs and the required time. By combining clinical presentation in patients with OT three useful diagnostic variables have been identified: age, duration of pain, vomiting. Presence of vomiting, short duration of abdominal pain and high CRP levels have great predictive value for the diagnosis of adnexal torsion. In those patients an exploratory laparoscopy should be performed without any doubt and/or delay. These data may aid physicians in the evaluation of abdominal pain in premenarchal girls

The Vocal Score Profile in Verdi's Characters

OBJECTIVES: Selecting the appropriate repertoire for an opera singer may be crucial for both the prevention of voice disorders and the career progression. Here, we reviewed the score of 14 Verdi's operas to gain the data for the creation of the vocal score profile of each role. MATERIALS AND METHODS: Seven musicians were involved in the analysis process. Notes were counted and reported as absolute and relative frequency. Pitch measurements included pitch range, percentage of high-pitched notes, percentage of medium-pitched notes, percentage of low-pitched notes, high-pitched and low-pitched notes rate, percentage of the notes in the passaggio, identification of the prevalent octave, percentage of notes in the prevalent octave, and percentage of notes in a moderate range tessitura. The total phonation time was calculated for each character. RESULTS: A heterogeneity among pitch and duration measurement was found among roles within the same voice type, leading to highly different vocal efforts required by the performer. CONCLUSIONS: Data on 67 Verdi characters were gained, and the vocal demand of each role was discussed. Potentially, these results may support singers, singing teachers, and vocal coaches in the selection of the repertoire. The data may also assist clinicians in the conduction of counseling and during eventual voice therapy. Future studies must investigate the predictive value of the vocal score profile in appraising the risk of vocal injury

An evaluation of |Vus| and precise tests of the Standard Model from world data on leptonic and semileptonic kaon decays

We present a global analysis of leptonic and semileptonic kaon decay data, including all recent results published by the BNL-E865, KLOE, KTeV, ISTRA+ and NA48 experiments. This analysis, in conjunction with precise lattice calculations of the hadronic matrix elements now available, leads to a very precise determination of |Vus| and allows us to perform several stringent tests of the Standard Model.Comment: LaTeX, 25 pages, 12 figures, 16 tables.

Long-Term Remission of an Aggressive Sebaceous Carcinoma following Chemotherapy

Sebaceous carcinoma (SC) is an uncommon neoplasm manifesting itself either in the eyelid or extraocularly in the head and neck area. Surgery is the standard of care. Irradiation is rarely proposed as monotherapy but is frequently administered as an adjuvant regimen following surgical resection. There is no known strategy concerning chemotherapeutic treatment in highly aggressive recurrent - or metastatic - forms of the disease. Our patient presented with an aggressive SC of the scalp recurring after multiple excisions and local radiotherapy. Chemotherapy with 5-fluorouracil, cisplatin and docetaxel was then initiated; 4 cycles were administered, followed by capecitabine maintenance. Shortly after starting chemotherapy, dermal lesions had completely disappeared and radiological response could be seen. The patient experienced an extended period (>20 months) of complete remission. In this report, we show an excellent response of a highly aggressive SC after a combination of chemotherapy as for head and neck cancers

The Choking game: a deadly game. Analysis of two cases of \u201cself-strangulation\u201d in young boys and review of the literature

The choking game is defined as a self-strangulation or strangulation by another person with the hands or a noose to achieve a brief euphoric state caused by cerebral hypoxia. Death may occur, but forensic pathologists often classify them as suicides or accidental deaths, without focusing on the possibility that they may result from a deliberate self-temporary-asphyxiation, turned into a deadly game. Presenting two fatal cases of self-strangulation involving an 11-year-old boy and a teenager of 15 years, the authors identify victims' characteristics and death scene's evidence, which may help to distinguish if a death is from an asphyxial suicide or an asphyxial gam

High Performances Corrugated Feed Horns for Space Applications at Millimetre Wavelengths

We report on the design, fabrication and testing of a set of high performance corrugated feed horns at 30 GHz, 70 GHz and 100 GHz, built as advanced prototypes for the Low Frequency Instrument (LFI) of the ESA Planck mission. The electromagnetic designs include linear (100 GHz) and dual shaped (30 and 70 GHz) profiles. Fabrication has been achieved by direct machining at 30 GHz, and by electro-formation at higher frequencies. The measured performances on side lobes and return loss meet the stringent Planck requirements over the large (20%) instrument bandwidth. Moreover, the advantage in terms of main lobe shape and side lobes levels of the dual profiled designs has been demonstrated.Comment: 16 pages, 7 figures, accepted for publication in Experimental Astronom
