We propose a color holographic projection using the space-division method, which can reconstruct two-dimensional image by one hologram and avoid superimposing of unwanted images on wanted image. calculated three holograms corresponding to red, green blue, then generated add holograms. The were optimized Gerchberg-Saxton algorithm for improvement reconstructed images. numerically evaluated quality in terms space YCbCr, compared method with that another method.
Objective While unexplained liver dysfunction is common, it sometimes difficult to identify its exact cause. One cause viral infections. The identification of viruses other than hepatitis B and C that because no methods simultaneously these have been established. aim this study was quickly multiple virus species. Methods A total 49 patients with undetermined inflammation were examined. majority had hematologic malignancies, some undergone bone marrow transplantation. Qualitative polymerase...
This paper proposes a particle volume reconstruction directly from an in-line hologram using deep neural network. Digital holographic conventionally uses multiple diffraction calculations to obtain sectional reconstructed images hologram, followed by detection of the lateral and axial positions, sizes particles focus metrics. However, resolution is limited numerical aperture optical system, processes are time-consuming. The method proposed here can simultaneously detect via network (DNN). We...
For this work, we introduced the use of binary amplitude for our proposed complex encoding a phase-only hologram. By principle, in hologram plane can be represented by and its phase. However, contains only phase information amplitude, which results degradation reconstruction quality from In method, approximating using finally record an original light We validated effectiveness method with two examples, generation Hermite-Gaussian beams.
• We saw three cases of optic nerve disturbance caused by frontal and frontoethmoidal mucopyoceles. A causative factor due to pyoceles might be not only related compression but also inflammatory invasion vascular disturbance. The importance axial coronal computed tomography scans is emphasized for evaluating the extension mucopyoceles relationship between lesion adjacent structures.

Cervical cancer is the second most common in women, and role of human papillomavirus (HPV) testing its etiology becoming increasingly important.We aimed to evaluate performance an artificial intelligence (AI)-assisted colposcopy system detecting high-risk (HR-HPV) subtypes cervical intraepithelial neoplasia (CIN) 2 patients.We conducted a post-hoc analysis previous observational study that developed AI algorithm for colposcopic images patients with CIN2.Out 78 HR-HPVs (HPV 16,18, 31, 33, 35,...
We assessed the prognostic impact of occult bone marrow involvement, determined by flow cytometry and/or polymerase chain reaction, in a population 117 consecutive patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL) treated rituximab plus cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP). Twenty-four (20.5%) had morphologically 16 (13.7%) 77 (65.8%) no involvement. Although pretreatment characteristics negative or involvement group were similar, severe...
Human papillomavirus subtypes are predictive indicators of cervical intraepithelial neoplasia (CIN) progression. While colposcopy is also an essential part cancer prevention, its accuracy and reproducibility limited because subjective evaluation. This study aimed to develop artificial intelligence (AI) algorithm that can accurately detect the optimal lesion associated with prognosis using colposcopic images CIN2 patients by utilizing objective AI diagnosis.We identified findings CIN2. We...
A 79-year-old man with a 2-month history of fever and weight loss was admitted to our hospital because an acute abdomen. Abdominal CT scans showed marked sectional thickening edema the small intestine. On laparotomy, 16-cm section intestine ischemic necrotic; therefore, segmentectomy performed. thrombus noted at stump mesenteric artery branch. Histopathological analysis resected revealed fibrin thrombi in both arteries veins. Furthermore, cluster large, abnormal lymphoid cells bordering...
Synchronous endometrial and ovarian cancer (SEOC) is a rare entity among gynecological cancers, which exhibits endometrioid histology in its early stages generally has good prognosis. However, diagnosis difficult recent reports have demonstrated that most clinically diagnosed cases of SEOC clonally related indicating metastatic cancer. The association with Lynch syndrome also not clearly understood. We herein present the case 41-year-old patient MSH2 mutation. was an adenocarcinoma mainly...
A 42-year-old woman with refractory ulcerative colitis (UC) developed ascites, pleural effusion, pretibial edema and severe anemia. Colonofiberscopic examination showed a bulky submucosal tumor in the sigmoid colon, which was histologically diagnosed as malignant lymphoma (diffuse large, B cell type). The resistant to chemotherapy. Autologous peripheral blood stem transplantation (PBSCT) effective; however, she died of infection after second PBSCT. Although association intestinal UC is rare,...
To investigate the association between providing leaflets to support pediatricians in explaining safety of human papillomavirus (HPV) vaccine and mother's decision vaccinate their daughters Japan.In this cross-sectional study, we conducted a survey mothers evaluate effect that were created profile HPV vaccine. Mothers who provided consent for vaccination before receiving an explanation excluded from study. The primary outcome was vaccinatetheir with after using our leaflets.Among 161...
In order to investigate penicillin resistance (Pcr) in Streptococcus pneumoniae from clinical sources Japan, a total 1, 127 strains of S. was collected at random 36 insititutions participating “Working group for Pcr pneumoniae” around the country 1993-1994. These were isolated more frequently sputum (38.2%), throat (31.4%), nasal discharge (16.4%), and otorrhea (5.7%). A small number isolates blood (19 strains; 1.8%), cerebrospinal fluid (11 1.0%), pleural (2 0.2%) included respectively....
A complex amplitude hologram can reconstruct perfect light waves. However, as there are no spatial modulators that able to display amplitudes, we need use amplitude, binary, or phase-only holograms. The images reconstructed from such holograms will deteriorate; address this problem, iterative optimization algorithms have been proposed. One of the utilizes a blank area help converge optimization; however, calculation time and memory usage involved increases. In study, propose reduce...
We encountered a rare case of cytotoxic molecule-positive and Epstein-Barr virus (EBV)-associated peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS), which was clinically preceded by polymyositis. A 50-year-old woman with 4-year history steroid-refractory polymyositis developed ulcerative skin swelling on her left arm. diagnosis molecule (TIA-1)-positive EBV-associated PTCL-NOS made the basis immunohistochemical molecular examinations biopsied brachial muscle. Combination...
We report a patient with aggressive systemic mastocytosis (SM), who exhibited eosinophilia and unusual destructive bone lesions. A 43-year-old female was referred to our hospital because of vertebral compression fracture, multiple lytic lesions, in February 2011. diagnosis SM made on the basis abnormal mast cells marrow, high serum tryptase levels, lesions including fractures. Polymerase chain reaction subsequent sequencing its products identify mutations c-kit yielded negative results...
Diffraction calculations, such as Fresnel diffraction and the angular spectrum method, are essential in optical simulations. These methods numerically calculated by discrete Fourier transform or fast (FFT). Although these calculations require FFT-based convolution, convolution becomes circular without using zero padding. Zero padding helps to avoid but increases calculation time memory usage. This paper proposes efficient implicit convolution. The proposed scheme accelerates time, reduces...
